The oleochemical industry is currently still dominatedby conventional chemistry, with biotechnology onlystarting to play a more prominent role, primarily withrespect to the biosurfactants or lipases, e.g. as detergents,or for biofuel production. A major bottleneckfor all further biotechnological applications is theproblem of the initial mobilization of cheap and vastlyavailable lipid and oil substrates, which are thento be transformed into high-value biotechnological,nutritional or pharmacological products. Under theEU-sponsored LipoYeasts project we are developingthe oleaginous yeast Yarrowia lipolytica into a versatileand high-throughput microbial factory that, byuse of specific enzymatic pathways from hydrocarbonoclasticbacteria, efficiently mobilizes lipidsby directing its versatile lipid metabolism towardsthe production of industrially valuable lipid-derivedcompounds like wax esters (WE), isoprenoid-derivedcompounds (carotenoids, polyenic carotenoid ester),polyhydroxyalkanoates (PHAs) and free hydroxylatedfatty acids (HFAs). Different lipid stocks (petroleum,alkane, vegetable oil, fatty acid) and combinationsthereof are being assessed as substrates in combinationwith different mutant and recombinant strains ofY. lipolytica, in order to modulate the composition andyields of the produced added-value products.

" Conversion of lignocellulose from palm (Elaeis guineensis) fruit fibre and physic (Jatropha curcas) nut shell into bio-oil Conversion of lignocellulose from palm (Elaeis guineensis) fruit fibre and physic (Jatropha curcas) nut shell into bio-oil."

Harmful gases are released into the atmosphere through burning of residues which is commonly practiced in Nigeria and can be attributed to climate change issues. Agricultural residues have the potentials to be used as energy and chemical source and meet its deficit in the country. This paper focuses on utilization of lignocellulosic materials obtained from two agricultural residues through renewable technology to produce bio-energy and chemical feedstock. The lignocellulosic materials were extracted from palm fruit (Elaeis guineensis) fibre and physic nut (Jatropha curcas) shell, and pyrolyzed under low temperature and pressure at various particle sizes. The main properties of solid (lignocellulosic) materials were tested and the bio-oil produced was analyzed using GC-MS. Results show proximate analyses (volatile, ash and fixed carbon contents) and ultimate analysis (carbon, oxygen, nitrogen, magnesium, phosphorus and zinc). The pH value of the bio-oil from both residues increased with increase in temperatures. The density, viscosity and calorific value of the palm and physic residue oil are 831.99 and 947.5 kg/m3, 0.695 and 1.58 cPa at room temperature, 22.33 and 14.169 kJ/g, respectively. Aromatics and other compounds are major dominant compounds in the palm fruit fibre oil which is characterized for bio-fuel production. Physic nut shell oil contains aromatic ethers, cyclic ethers, secondary amides and organic halogen compound which are important chemical feedstock. Conversion of these residues to useful products will alleviate the energy supply deficit, improve social and economic development, promote clean and healthy atmosphere of the nation and significantly contribute to global climate change mitigation.

Abstract: Femoral artery intima - media thickness is a reliable surrogate marker of atherosclerosis and is important for prediction of coronary and peripheral vascular disease, but is seldom reported among black Sub Saharan African populations. This study, therefore, aimed at describing the intima - media thickness of the femoral artery in relation with age, gender and some of its geometric factors. Materials for this study were obtained during autopsy from 208 adult black Kenyans (154 males, 54 females, mean age 36.4 years) who had died of non cardiovascular causes. Those with history of cardiovascular risk factors were excluded. Femoral artery was exposed by dissection. Terminal branching pattern was recorded, and length and bifurcation angle measured. Materials for determination of intima - media thickness were processed routinely for paraffin embedding and sectioning. Five micron sections were stained with Mason’s trichrome, examined with light microscope and pictures taken. The images were digitized and intimal and medial thickness determined according to the protocol by Nakashima et al. [1]. The mean intima - media thickness was 0.76 ± 0.016 mm. It increased with age and was higher in males than females; for trifurcations (0.95 ± 0.032 mm) and also short arteries and those with wide bifurcation angles. Age and gender differences and those between arterial trifurcation and bifurcation attained statistical significance. In conclusion, the mean femoral intima-media thickness of the black Kenyan population studied is higher than those reported for Caucasian populations, increases with age and is higher in males and cases of trifurcation. This suggests that the study population is susceptible to atherosclerosis and that variant terminal branching pattern constitutes a geometric risk factor for atherosclerosis. We recommend ultrasound screening for those at risk.

" Long-term Virologic Response and Genotypic Resistance Mutations in HIV-1 Infected Kenyan Children on Combination Antiretroviral Therapy." J Acquir Immune Defic Syndr. 2012 Nov 28. [Epub ahead of print]. 2012. Abstract

Abstract
BACKGROUND:
HIV-infected children may require the use of combination antiretroviral treatment (cART) into adulthood. However, regimens are limited to first- and second-line in many African settings. Therefore, understanding the long-term rate of virologic failure and drug resistance during prolonged antiretroviral treatment is important for establishing treatment strategies in African pediatric cohorts.
METHODS:
Children ages 18 months to 12 years initiated first-line cART and were followed every 1-3 months, for up to 5.5 years. Treatment was switched to second-line based on clinical and immunologic criteria according to national guidelines. Virologic failure was determined retrospectively as defined by ≥2 viral loads >5000 copies/mL. Drug resistance was assessed during viral failure by population-based sequencing.
RESULTS:
Among 100 children on first-line cART followed for a median 49 months, 34% experienced virologic failure. Twenty-three (68%) of the 34 children with viral failure had detectable resistance mutations, of whom 14 (61%) had multi-class resistance. Fourteen (14%) children were switched to second-line regimens and followed for a median of 28 months. Retrospective analysis revealed that virologic failure had occurred a median of 12 months prior to the switch to second-line. During prolonged first-line treatment in the presence of viral failure, additional resistance mutations accumulated, however, only 1 (7%) of 14 children had persistent viremia during second-line treatment.
DISCUSSION:
Virologic suppression was maintained on first-line cART in two-thirds of HIV-infected children for up to 5 years. Switch to second-line based on clinical/immunologic criteria occurred ∼1 year after viral failure, but the delay did not consistently compromise second-line treatment.

Abstractstructure_and_process_factors_that_influence_patients_perception_of_inpatient_psychiatric_nursing_care_at_mathari_hospital__nairobi.pdf

To explore structure and process factors which influence patients' perception of quality inpatient psychiatric nursing care at Mathari hospital. This was a cross-sectional study of 236 inpatients selected by stratified random sampling. Competence to give consent was determined by a minimum score of 24 on Mini Mental State Examination. Patients were interviewed using a semi-structured questionnaire. Differences in proportions of variables were determined by calculating confidence interval and summary chi-squared statistics. P-values of < or =0.05 were considered significant. Majority of patients (87%) were aged 20-49 years with 43% having stayed in the ward for over a month. Structure factors related to patients' perception of care included physical environment, being happy with the way the ward looked was significantly related to satisfaction with care (chi(2) = 5.506, P = 0002). Process factors significantly related to patients' satisfaction with care included nurses providing patients with information on prescribed medicines (chi(2) = 10.50, P = 00012). Satisfaction with care was positively related to ability to recommend someone for admission in the same ward (chi(2) = 20.2, P = 00001). Structure and process factors identified as influencing patients' perception of care were physical environment and nurses' qualities that fit within the characteristics of Peplau's Interpersonal Relations Theory.

JONYO DRFREDOPIYO. "- Ethnicity in the electoral Process in Kenya.". In: East and Central African Journal of Pharmaceutical Sciences. F.N. kamau, G. N Thothi and I.O Kibwage; 2002. Abstract

Ampicillin products, 20 capsules, 2 tablets and 23 dry suspensions were evaluated for quality by liquid chromatography at theDrug Analysis Unit University of Nairobi. Four capsule formulations failed limits on content. The Ampicillin content in 5 suspensions dropped below 80% on storage, but had no correlation to decrease in chemical content

Ampicillin is semi-synthetic penicillin used in the management of infections caused by sensitive microorganisms. Microbial resistance against ampicillin is well documented and cross-resistance is a common problem among the penicillins. Development of resistance is always associated with exposure of microorganisms to sub-lethal levels of drugs. The quality administered and especially low content of ampicillin in dosage form could therefore contribute to the development of resistance.

Work on the quality of drugs in the period 1982 to 1992 has shown presence of poor quality penicillin products in the market [1-4]. This observation was recently reinforced by the findings on quality of phenoxymethylpenicillin syrups [5]. The extensive use of ampicillin in kenya as one of the drugs on the essential drugs list of Ministry of Health [6] led to observed increase in resistance. It was recently replaced by amoxicillin.

The communication presents findings on the quality of ampicillian capsules and tablets and dry syrups found on the Kenyan market using liquid chromatography (LC). The preparations were from private and public sources including those submitted to the ministry of Health drug regulatory authority. The latter are intended for marketing in Kenya after registration, and for the purpose of this paper are treated as being on the market.

{ The Blantyre coma scale (BCS) is used to assess children with severe falciparum malaria, particularly as a criterion for cerebral malaria, but it has not been formally validated. We compared the BCS to the Adelaide coma scale (ACS), for Kenyan children with severe malaria. We examined the inter-observer agreement between 3 observers in the assessment of coma scales on 17 children by measuring the proportion of agreement (PA), disagreement rate (DR) and fixed sample size kappa (kappa n). We assessed the sensitivity and specificity of the scales in detecting events (seizures and hypoglycaemia) in 240 children during admission and the usefulness of the scales in predicting outcome. There was considerable disagreement between observers in the assessment of both scales (BCS: PA = 0.55

ABSTRACT: OBJECTIVES: To identify the main barriers to utilisation of eye care services among the slum population of Kibera in Nairobi, Kenya. DESIGN: Community based survey. SETTING: Kibera slums, Nairobi City, Kenya. SUBJECTS: Randomly selected 1,438 Kibera slum dwellers aged over two years. RESULTS: Majority of subjects (83.3%) do not utilise the nearby well-established eye clinics. Twenty one percent of those with poor vision do not seek treatment at all. The main barriers to seeking eye care services were lack of money, ignorance and the problem not causing much discomfort to warrant medical attention. There was significant, association between the level of education and health seeking behaviour (P = 0.008). CONCLUSION: Majority of Kibera slum dwellers have no access to eye care. RECOMMENDATION: There is need to establish a comprehensive primary eye care project to provide low cost but quality services affordable to Kibera slum dwellers.

Land use and land cover changes are important processes that influence the dynamics of human-wildlife conflicts. Effective management of human-wildlife conflicts requires the participation of local communities and other stakeholders. However, local communities need to identify and understand resource use change and their role in the process, so as to facilitate uptake of appropriate land resource management strategies aimed at counteracting human-wildlife conflicts. Approaches aimed at changing local community behavior towards natural resource use require appropriate technologies that bridge the technology and knowledge gaps between policy makers and local communities. PGIS was used to assess and educate local communities on land use and land cover changes as well as visualize the problems associated with resource changes. Local communities were found to be significantly knowledgeable about resource changes and their causes. PGIS compared well to conventional GIS analysis and therefore an appropriate technology for analysing and monitoring landuse and land cover changes.

"8.Evaluation of a single round polymerase chain reaction assay using dried blood spots for diagnosis of HIV-1 infection in infants in an African setting." BMC Pediatr. 2011 Feb 18;11:18. doi: 10.1186/1471-2431-11-18.. 2011. Abstract

Abstract
BACKGROUND:
The aim of this study was to develop an economical 'in-house' single round polymerase chain reaction (PCR) assay using filter paper-dried blood spots (FP-DBS) for early infant HIV-1 diagnosis and to evaluate its performance in an African setting.
METHODS:
An 'in-house' single round PCR assay that targets conserved regions in the HIV-1 polymerase (pol) gene was validated for use with FP-DBS; first we validated this assay using FP-DBS spiked with cell standards of known HIV-1 copy numbers. Next, we validated the assay by testing the archived FP-DBS (N=115) from infants of known HIV-1 infection status. Subsequently this 'in-house' HIV-1 pol PCR FP-DBS assay was then established in Nairobi, Kenya for further evaluation on freshly collected FP-DBS (N=186) from infants, and compared with findings from a reference laboratory using the Roche Amplicor® HIV-1 DNA Test, version 1.5 assay.
RESULTS:
The HIV-1 pol PCR FP-DBS assay could detect one HIV-1 proviral copy in 38.7% of tests, 2 copies in 46.9% of tests, 5 copies in 72.5% of tests and 10 copies in 98.1% of tests performed with spiked samples. Using the archived FP-DBS samples from infants of known infection status, this assay was 92.8% sensitive and 98.3% specific for HIV-1 infant diagnosis. Using 186 FP-DBS collected from infants recently defined as HIV-1 positive using the commercially available Roche Amplicor v1.5 assay, 178 FP-DBS tested positive by this 'in-house' single-round HIV-1 pol PCR FP-DBS PCR assay. Upon subsequent retesting, the 8 infant FP-DBS samples that were discordant were confirmed as HIV-1 negative by both assays using a second blood sample.
CONCLUSIONS:
HIV-1 was detected with high sensitivity and specificity using both archived and more recently collected samples. This suggests that this 'in-house' HIV-1 pol FP-DBS PCR assay can provide an alternative cost-effective, reliable and rapid method for early detection of HIV-1 infection in infants.

This paper reports on a prospective study conducted between June 1990 and June 1992 to determine method acceptability, user satisfaction and continuation rates for three highly effective and reversible contraceptive methods currently available in Kenya: the CuT 380A (IUCD), the injectable, Depo-Provera and the low-dose oral contraceptive pill, Microgynon. A non-randomised sample of volunteer participants was used. One thousand and seventy-six users were followed up for a period of one year or up to the time of discontinuation of the method, whichever came earlier. Analysis revealed method specific differences in users' characteristics. The OC users were younger and had fewer children than the IUCD or Depo-Provera users. The Depo-Provera users were older, and had the largest family sizes. Many OC users (almost 40%) were single, while almost three-quarters of IUCD and Depo-Provera users were married. IUCD users were also more educated compared to OC and Depo-Provera users. Survival analysis was used to calculate cumulative life table discontinuation rates by method for the 12 month period. Discontinuation rates were highest for OC users (80%) and lowest for IUCD users (20%) and intermediate for Depo-Provera users (39%). Ninety percent of OC and Depo-Provera users and 86% of IUCD users said they were satisfied with their respective methods. While OCs are among the most popular family planning methods in Kenya, they are also one of the most problematic, while IUCD has the fewest compliance problems. Service providers need to address the issue of high discontinuation rates among the young OC users.

This paper reports on a prospective study conducted between June 1990 and June 1992 to determine method acceptability, user satisfaction, and continuation rates for three highly effective and reversible contraceptive methods currently available in Kenya: the CuT 380A IUD; the injectable Depo-Provera; and the low-dose oral contraceptive Microgynon. A nonrandomized sample of volunteer participants was used. 1076 users were followed up for a period of 1 year or up to the time of discontinuation of the method, whichever came earlier. Analysis revealed method-specific differences in users' characteristics. The OC users were younger and had fewer children than the IUD or Depo-Provera users. The Depo-Provera users were older and had the largest family sizes. Many OC users (almost 40%) were single, while almost three-quarters of the IUD and Depo-Provera users were married. IUD users were also more educated compared to OC and Depo-Provera users. Survival analysis was used to calculate cumulative life table discontinuation rates by method for the 12-month period. Discontinuation rates were highest for OC users (80%), lowest for IUD users (20%), and intermediate for Depo-Provera users (39%). 90% of OC and Depo-Provera users and 86% of IUD users said they were satisfied with their respective methods. While OCs are among the most popular family planning methods in Kenya, they are also one of the most problematic, while IUDs have shown the fewest compliance problems. Service providers need to address the issue of high discontinuation rates among young OC users

Asian Economic and Social Society; 1995. Abstract
The factors responsible for the explosive spread of human immunodeficiency virus type 1 (HIV-1) in sub-Saharan Africa continue to be identified and debated. One of the most controversial factors has been male circumcision. This cross-sectional study was conducted to measure the association between circumcision status and infection with HIV-1 among men with genital ulcer disease. Eight hundred and ten men participated in the study, of whom 190 (23%) were HIV-1-positive. A logistic regression model adjusted for behavioral and historical showed that HIV-1 positivity was independently associated with being uncircumcised (adjusted odds ratio [OR], 4.8; 95% confidence interval [CI], 3.3-7.2) and with a history of urethral discharge (adjusted OR, 2.0; 95% CI, 1.4-2.8). This association could not be explained by measures of sexual exposure to HIV-1 among this population. Male circumcision should be considered as an intervention strategy for AIDS control.

In: Environmental Technology (U.K.) 23, 1285-1292. Association of Africa Universities; 2002. Abstract

Accumulation, distribution and metabolism of ring labelled, "C-1,1,1, - trichloro-2,2-bis(p-chlorophenyl)ethane (p,p'-DDT) in a model marine aquatic ecosystem consisting of sea water, sediment, oysters (Isognomonon alatus) and Humbug fish (Dascillus aruanus) were studied in the laboratory. "C-p,p'-DDT distributes rapidly in the ecosystem immediately after application on the water surface with reduction of its concentration in the water phase from 1.18 ng g"1 to 0.71 ng g'after 2 hours and an increase in its content in the sediment and oysters. The bioconcentration factor reached a maximum of 19x 10* in oysters, and 1657 in Humbug fish after 24 hours. The sediment concentration reached 117 ng g"1 after 168 hours from start of application. A peak bioconcentration factor of 111 x 103 was calculated after 120 hours when 0.24 mg kg"1 of '^>p,p'-DDT was maintained through dosing every 24 hours with 0.002 mg kg' of a mixture of labelled and non-labelled pesticide. The rate of depuration of accumulated "C-p,p'-DDT sediment residues was up to 78.3% after 24 hours while oysters lost only 14.0% during the same period. The loss in Humbug fish was only 22.2% in three days. Volatilisation and sorption losses from seawater alone (without sediment/biota) were found to be very high in the range of 73.8 - 91.5% over 24 h for p,p'-DDT in aerated and non-aerated ecosystem. Gas chromatograph and TLC analysis of water, sediment and oyster samples revealed presence of p,p'-DDT and substantial amounts of p,p'-DDE and p,p'-DDD three days after pesticide dosage.

Data available on the role of the opioid systems of the naked mole-rat in nociception is scanty and unique compared to that of other rodents. In the current study, the effect of DAMGO, DPDPE and U-50488 and U-69593 on formalin-induced (20 μl,10%) nociception were investigated. Nociceptive-like behaviors were quantified by scoring in blocks of 5 min the total amount of time (s) the animal spent scratching/biting the injected pawin the early (0–5 min) and in the late (25–60 min) phase of the test. In both the early and late phases, administration of 1 or 5 mg/kg of DAMGO or DPDPE caused a naloxone-attenuated decrease in the mean scratching/biting time. U-50488 and U-69593 at all the doses tested did not significantly change the mean scratching/biting time in the early phase. However, in the late phase U-50488 or U-69593 at the highest doses tested (1 or 5 mg/kg or 0.025 or 0.05 mg/kg, respectively) caused a statistically significant and naloxone-attenuated decrease in the mean scratching/biting time. The data showed that mu, delta or kappa-selective opioids causes antinociception in the formalin test in this rodent, adding novel information on the role of opioid systems of the animal on pain regulation.

BACKGROUND:

Active management of the third stage of labour reduces the risk of post-partum haemorrhage. We aimed to assess whether controlled cord traction can be omitted from active management of this stage without increasing the risk of severe haemorrhage.

METHODS:

We did a multicentre, non-inferiority, randomised controlled trial in 16 hospitals and two primary health-care centres in Argentina, Egypt, India, Kenya, the Philippines, South Africa, Thailand, and Uganda. Women expecting to deliver singleton babies vaginally (ie, not planned caesarean section) were randomly assigned (in a 1:1 ratio) with a centrally generated allocation sequence, stratified by country, to placental delivery with gravity and maternal effort (simplified package) or controlled cord traction applied immediately after uterine contraction and cord clamping (full package). After randomisation, allocation could not be concealed from investigators, participants, or assessors. Oxytocin 10 IU was administered immediately after birth with cord clamping after 1-3 min. Uterine massage was done after placental delivery according to local policy. The primary (non-inferiority) outcome was blood loss of 1000 mL or more (severe haemorrhage). The non-inferiority margin for the risk ratio was 1·3. Analysis was by modified intention-to-treat, excluding women who had emergency caesarean sections. This trial is registered with the Australian and New Zealand Clinical Trials Registry, ACTRN 12608000434392.

FINDINGS:

Between June 1, 2009, and Oct 30, 2010, 12,227 women were randomly assigned to the simplified package group and 12,163 to the full package group. After exclusion of women who had emergency caesarean sections, 11,861 were in the simplified package group and 11,820 were in the full package group. The primary outcome of blood loss of 1000 mL or more had a risk ratio of 1·09 (95% CI 0·91-1·31) and the upper 95% CI limit crossed the pre-stated non-inferiority margin. One case of uterine inversion occurred in the full package group. Other adverse events were haemorrhage-related.

INTERPRETATION:

Although the hypothesis of non-inferiority was not met, omission of controlled cord traction has very little effect on the risk of severe haemorrhage. Scaling up of haemorrhage prevention programmes for non-hospital settings can safely focus on use of oxytocin.

OBJECTIVE: To determine the prevalence of acute coronary syndromes among type 2 diabetic patients presenting to Accident and Emergency department. DESIGN: Prospective cross-sectional study. SETTING: Kenyatta National Hospital, a tertiary teaching and referral hospital. SUBJECTS: Type 2 diabetic patients with ischaemic electrocardiograms (ECG). MAIN OUTCOME MEASURES: Demographics, clinical symptoms, cardiovascular status and risk factors--central obesity, hypertension, dyslipidaemia, smoking. RESULTS: From 12,307 accident and emergency attendees, 400 (33%) diabetics aged > OR =30 years were screened with a resting ECG and 95 (24%) with ischaemic ECG were recruited; age range 41-87 years, 60% were male; diabetes duration ranged 0-30 years with 8.4% being newly diagnosed. The commonest enrolling ECG feature was nonspecific ST-T changes. The commonest presenting complaint were fatigue and dyspnoea. Majority had three coronary artery disease (CAD) risk factors: obesity 86%, elevated LDL 73% and hypertension 60%. Therapy in use was OHA 43%, insulin 42%, insulin and OHA 1%; prophylactic aspirin 14.7% and statins 8.4%. Thirty four (35.8%) were classified as acute coronary syndrome (ACS); 29 (30.5%) acute myocardial infarction (ACS-AMI) and five (5.2%) unstable angina (ACS-UA). Majority (79.4%) of the ACS presented more than six hours after symptom onset and majority had features of acute left ventricular failure. CONCLUSIONS: Acute coronary syndrome accounted for 35% of the morbidity in type 2 diabetics with ischaemic ECG's presenting to KNH accident and emergency department; patients presented late and 80% were not on CAD prophylactic therapy.

Objective: Cytomegalovirus (CMV) coinfection may influence HIV-1 disease progression
during infancy. Our aim was to describe the incidence of CMV infection
and the kinetics of viral replication in Kenyan HIV-infected and HIV-exposed uninfected
infants.
Methods: HIV-1 and CMV plasma viral loads were serially measured in 20 HIVexposed
uninfected and 44 HIV-infected infants born to HIV-infected mothers.
HIV-infected children were studied for the first 2 years of life, and HIV-exposed
uninfected infants were studied for 1 year.
Results: CMVDNAwas detected frequently during the firstmonths of life; by 3months of
age,CMVDNAwasdetectedin90%ofHIV-exposeduninfectedinfantsand93%of infants
the first detection of virus and declined rapidly thereafter. CMV peak viral loads were
significantlyhigher in theHIV-infectedinfantscomparedwith theHIV-exposeduninfected
infants (mean3.2versus2.7 log10CMVDNAcopies/ml, respectively,P¼0.03).Thedetection
of CMV DNA persisted to 7–9 months post-CMV infection in both the HIV-exposed
uninfected (8/17, 47%) and HIV-infected (13/18, 72%, P¼0.2) children. Among HIVinfected
children, CMV DNA was detected in three of the seven (43%) surviving infants
tested between 19 and 21 months post-CMV infection. Finally, a strong correlation was
found between peak CMV and HIV-1 viral loads (r¼0.40, P¼0.008).
Conclusion: Acute CMV coinfection is common in HIV-infected Kenyan infants. HIV-1
infection was associated with impaired containment of CMV replication.

"Acute cytomegalovirus infection is associated with increased frequencies of activated and apoptosis-vulnerable T cells in HIV-1-infected infants.". 2012. AbstractWebsite

Cytomegalovirus (CMV) coinfection is associated with infant HIV-1 disease progression and mortality. In a cohort of Kenyan HIV-infected infants, the frequencies of activated (CD38(+) HLA-DR(+)) and apoptosis-vulnerable (CD95(+) Bcl-2(-)) CD4(+) and CD8(+) T cells increased substantially during acute CMV infection. The frequency of activated CD4(+) T cells was strongly associated with both concurrent CMV coinfection (P = 0.001) and HIV-1 viral load (P = 0.05). The frequency of apoptosis-vulnerable cells was also associated with CMV coinfection in the CD4 (P = 0.02) and CD8 (P < 0.001) T cell subsets. Similar observations were made in HIV-exposed uninfected infants. CMV-induced increases in T cell activation and apoptosis may contribute to the rapid disease progression in coinfected infants.

BACKGROUND:
Clinical signs and symptoms of acute human immunodeficiency virus (HIV) infection in infants are not well characterized.
METHODS:
Serial clinical assessments and HIV PCR assays were conducted in a cohort of children born to HIV-seropositive mothers from birth to 2 years of age. Acute HIV infection visits were defined as those up to 3 months prior to and including the visit at which HIV DNA was first detected. Noninfection visits included all visits at which the child had test results negative for HIV, including the last visit at which a test result negative for HIV DNA was obtained in children who later acquired HIV infection. Differences in the prevalence of symptoms at acute infection versus noninfection visits were determined overall and were stratified by age at infection (<2 months vs. >or=2 months). HIV RNA was measured serially in infected infants and was compared between infants with and infants without symptoms of acute HIV infection.
RESULTS:
There were 125 acute infection visits (among 56 infants) and 3491 noninfection visits (among 306 infants). Acute HIV infection was associated with rash (odds ratio [OR], 1.8; 95% confidence interval [CI], 1.1-2.8), failure to thrive (OR, 1.9; 95% CI, 1.0-3.5), and lymphadenopathy (OR, 2.5; 95% CI, 1.4-4.8). Acute HIV infection was associated with lymphadenopathy (OR, 2.6; 95% CI, 1.3-5.0) in infants <2 months of age and with pneumonia (OR, 3.2; 95% CI, 1.1-9.3) and dehydration (OR, 6.0; 95% CI, 1.9-18.5) in infants >or=2 months of age. Infant peak viral load and mortality were not associated with symptoms of acute HIV infection. However, infants with symptoms had higher viral levels later in the course of infection than did those without symptoms (P=.05).
CONCLUSIONS:
Infants may manifest symptoms early during the course of HIV infection, and symptoms of acute HIV infection may correlate with poor viral control. Rash, failure to thrive, lymphadenopathy, pneumonia, and dehydration may signify acute HIV infection in infants.

Ngure RM, Eckersall PD, Jennings FW, Mburu J, Burke J, Mungatana N, MURRAY M. "Acute phase response in mice experimentally infected with Trypanosoma congolense: a molecular gauge of parasite-host interaction.". 2007. AbstractWebsite

Mice infected with Trypanosoma congolense developed a severe anaemia 1 week after infection, which persisted till treatment with diminazine aceturate when the packed cell volume (PCV) recovered to pre-infection levels. This was accompanied by a marked increase in the plasma levels of the acute phase proteins (APP), serum amyloid P-component (SAP) and haptoglobin (Hp). The initial peak levels of Hp and SAP were attained 7 and 12 days post-infection (DPI), respectively. Thereafter SAP levels decreased significantly to near pre-infection levels, but later increased even after treatment to give a second peak 34 DPI after which there was a decline till the study was terminated. The Hp levels on the other hand decreased to an intermediate level after the initial peak increasing to a second peak 22 DPI. Thereafter Hp decreased significantly following diminazine aceturate treatment to reach pre-infection levels within 5 days post-treatment. This indicates that T. congolense-infected mice develop severe anaemia accompanied by an acute phase response leading to an increase in SAP and Hp but that following treatment divergent responses occurred indicating differences in the pathways for stimulation of the APP. Haptoglobin was shown to be an earlier indicator of infection and a better marker in monitoring the response to treatment.

Abstract: A case of acute respiratory distress syndrome due to babesiosis is reported in a 5 years old male Japanese sptiz. The patient was noticed to have developed sudden dyspnoea. The main presenting clinical signs included laboured breathing, broad-base stance but preferred recumbency, pallour and seizures. Blood smears from the ear tips revealed presence of multiple Babesia parasites in the erythrocytes. Hematology results showed slight leucocytosis, severe anemia and thrombocytopenia. Additionally, urinalysis revealed renal pathology and presence of leucocytes in urine. Despite aggressive measures to stabilize the patient, it died within an hour. Autopsy results also confirmed Babesiosis with generalized icterus.

Background. The host immune response against mucosally-acquired pathogens may be influenced by the mucosal immune milieu during acquisition. Since Neisseria gonorrhoeae can impair dendritic cell and T cell immune function, we hypothesized that co-infection during HIV acquisition would impair subsequent systemic T-cell responses.   Methods. Monthly screening for sexually transmitted infections (STIs) was performed in high risk, HIV seronegative Kenyan female sex workers as part of an HIV prevention trial. Early HIV-specific CD8+ T cell responses and subsequent HIV viral load set point were assayed in participants acquiring HIV, and were correlated with the presence of prior genital infections during HIV acquisition.   Results. Thirty-five participants acquired HIV during follow up, and 16/35 (46%) had a classical STI at the time of acquisition. N. gonorrhoeae co-infection was present during HIV acquisition in 6/35 (17%), and was associated with an increased breadth and magnitude of systemic HIV-specific CD8+ T-cell responses, using both interferon- (IFNg) and MIP-1 beta (MIP1b) as an output. No other genital infections were associated with differences in HIV-specific CD8+ T cell response, and neither N. gonorrhoeae nor other genital infections were associated with differences in HIV plasma viral load at set point.   Conclusion. Unexpectedly, genital N. gonorrhoeae infection during heterosexual HIV acquisition was associated with substantially enhanced HIV-specific CD8+ T-cell responses, although not with differences in HIV viral load set point. This may have implications for the development of mucosal HIV vaccines and adjuvants.

OBJECTIVE: To determine the prevalence of HCV infection and HCV/HIV co-infection among voluntary blood donors at the National Blood Transfusion Centre and clients at the Kenyatta National Hospital HIV-Voluntary Counseling and Testing (VCT) Centre. DESIGN: A prospective cross-sectional descriptive study. SETTING: Kenyatta National Hospital, a tertiary referral and teaching hospital and the National Blood Transfusion Services Centre, Nairobi. SUBJECTS: Volunteer blood donors and VCT attendants. RESULTS: The prevalence of HCV/HIV co-infection among 6154 blood donors in the NBTSC was very low, at 0.02. The HIV prevalence among the 353 KNH HIV-VCT clients was 9.3%, none of the clients tested positive for HCV. The incidence of risk factors in the persons with HCV and/or HIV infection(s) was low. CONCLUSION: The prevalence of HCV infection among pre-screened volunteer blood donors was low. However the current practice of screening all donated blood for HCV remains indispensable to prevent its transmission to blood recipients.

Ethnopharmacological relevance: Traditional medicines play an important role in the management of chronically painful and debilitating joint conditions, particularly in the rural Africa. However, their potential use as sources of medicines has not been fully exploited. The present study was carried to find the medicinal plants traditionally used to manage chronic joint pains in Machakos and Makueni counties in Kenya. Materials and methods: To obtain this ethnobotanical information, 30 consenting traditional herbal med-ical practitioners were interviewed exclusively on medicinal plant use in the management of chronic joint pains, in a pre-planned workshop. Results and discussion: In this survey, a total of 37 plants belonging to 32 genera and 23 families were cited as being important for treatment of chronic joint pains.

"Adapting clinical practice guidelines for diabetic retinopathy in Kenya: process and outputs." Implement Sci. 2018;13(1):81. Abstract

The use of clinical practice guidelines envisages augmenting quality and best practice in clinical outcomes. Generic guidelines that are not adapted for local use often fail to produce these outcomes. Adaptation is a systematic and rigorous process that should maintain the quality and validity of the guideline, while making it more usable by the targeted users. Diverse skills are required for the task of adaptation. Although adapting a guideline is not a guarantee that it will be implemented, adaptation may improve acceptance and adherence to its recommendations.

Abstract

Rising demand for energy is one of the major challenges facing the world today and charcoal is a principal fuel in Kenya. Faced with energy poverty many poor households turn to briquette making. This study assessed the additional cooking fuel obtained from recycling charcoal dust into charcoal briquettes. It applied Life Cycle Assessment (LCA) to assess the global warming potential (GWP) from use of charcoal and production of briquettes from charcoal dust and cooking a traditional meal for a standard household of five people. Native vegetation of Acacia drepanolobium and a low efficiency kiln were considered the common practice, while an Acacia mearnsii plantation and a high efficiency kiln was used as an alternative scenario. Charcoal and kerosene were considered as reference fuels. Recovering charcoal dust for charcoal briquettes supplied an additional 16% cooking fuel. Wood carbonization and cooking caused the highest GWP, so there is a need for technologies to improve the efficiency at these two stages of charcoal briquettes and charcoal supply chain. Supplying energy and cooking a traditional meal in a combined system using charcoal and recovering charcoal dust for charcoal briquettes and charcoal alone accounted for 5.3–4.12 and 6.4–4.94 kg CO2 eq. per meal, respectively, assuming trees were not replanted. These amounts declined three times when the carbon dioxide from the carbonization and cooking stages was assumed to be taken up by growing biomass. This requires replanting of trees cut down for charcoal if the neutral impact of biomass energy on GWP is to be maintained.

BACKGROUND: The khat habit is a widespread phenomenon which has in the past two decades spread to parts of Western Europe and North America from Eastern Africa and the Arabian Peninsula. Although khat has been identified as one of the most commonly abused substances in Kenya, restrictions on cultivation, trade and usage have been non-existent since its legalisation in 1977. OBJECTIVE: To describe the socio-economic effects of khat chewing in Ijara District in the North Eastern Province of Kenya. DESIGN: Cross sectional study. SETTING: Ijara District, North Eastern Kenya. SUBJECTS: Fifty respondents were interviewed. RESULTS: Eighty eight percent of the respondents were khat chewers, and the majority (80%) had family members who engaged in the khat habit. There was a general lack of education on the negative effects of khat chewing. Due to reported mood changes and withdrawal symptoms when not chewing khat, many respondents used more than half of their domestic budgets on khat, but few (28%) perceived this as a waste of resources. Fifty four percent of khat chewers typically started the habit during the day, implying a waste of time for productive work. However, only 40% of the persons interviewed admitted that the drug affected work performance negatively. The khat habit was associated with strain on family relationships, anti-social behaviour and health effects such as insomnia. CONCLUSION: In spite of the negative socio-economic impact of khat in Ijara District, khat consumption remains a widespread habit.

The decision to pay out earnings or retain dividends has been a subject of debate for many scholars. The effect of dividend on the firm value and cost of capital have been covered in attempt to resolve the dividend puzzle. This research paper tests the applicability of constant dividend model by companies listed at the Nairobi stock exchange. Data was collected from annual reports and share price schedules obtained from Nairobi stock exchange and Capital market Authority for a population of 20 companies that paid dividends consistently from 2002 to 2008. The data was then analyzed by re-computing the dividends that should have been paid if the dividend constant model was applied. This recomputed figure was later compared to the dividend as paid out by the companies thought the years of study. Paired sample t-test statistic was also performed to determine whether there is a significant difference between the two dividend figures. The findings of the research established that the dividend model was not employed by the companies listed at the Nairobi stock exchange. Most firms instead adopted stable and predictable policy where a specific amount of dividend per share each year was paid periodically. In some years there was a slight adjustment of the dividend paid after an increase in earnings, but only by a sustainable amount. The study shows that the relationship between the stock market prices and the dividend paid from the constant dividend model is uneven from one year to another and where there was a relationship it was insignificant. Though a share would be highly priced, a high dividend per share was not always declared.

Ethnopharmacological relevance: Traditional medicines play an important role in the management of chronically painful and debilitating joint conditions, particularly in the rural Africa. However, their potential use as sources of medicines has not been fully exploited. The present study was carried to find the medicinal plants traditionally used to manage chronic joint pains in Machakos and Makueni counties in Kenya. Materials and methods: To obtain this ethnobotanical information, 30 consenting traditional herbal med-ical practitioners were interviewed exclusively on medicinal plant use in the management of chronic joint pains, in a pre-planned workshop. Results and discussion: In this survey, a total of 37 plants belonging to 32 genera and 23 families were cited as being important for treatment of chronic joint pains. The most commonly cited plant species were Pavetta crassipes K. Schum, Strychnos henningsii Gilg., Carissa spinarum L., Fagaropsis hildebrandtii (Engl.) Milve-Redh. and Zanthoxylum chalybeum Engl.

Background: Hypertension, a major risk factor for cardiovascular disease is rapidly attaining epidemic portions in Africa and is strongly associated with urbanisation. We studied a population of Kenyans of Somali ethnicity; traditionally a semi nomadic pastoralist community but who have settled in local urban centres and thereby subject to lifestyle influences of urbanisation. This represents a unique position in the epidemiological transition.

Methods: A cross-sectional community survey carried out in Garissa town, the administrative centre for North Eastern Province, with a population of 196,062. Utilising cluster sampling 2200 adults were recruited. WHO STEPS questionnaire was followed by measurement of BP; height and weight for BMI; waist and hip circumference. Non fasting blood specimens were taken for random blood sugar and total cholesterol.

Results: Data for 1823 subjects, 702 males, 1121 females were complete and analysed. Mean age was 38.5 (range 18-96 years), 82% less than 50 years. Hypertension prevalence was 12.6% (95% CI 11.1-14.2%) and increased with age reaching 38.5 % in over 65years; with a 61% detection rate. Concurrent risk factors were: diabetes 3.7% (2.9-4.7); Overweight 23.9% (21.9-25.9%), Obesity 12.6% (11.2-14.3%), Abdominal obesity (WHR)20.4% (18.5-22.3%), Smoking 5.2% (4.4-6.5%) and hypercholesterolemia 16.9%(11.0-24.3%). Male sex, increasing age, diabetes and over weight were independently associated with hypertension.

Discussion: Despite the young age, this unique and previously unstudied urban & semi-urban population has a high prevalence of hypertension and cardiovascular risk factors showing evidence of epidemiological transition to NCDs. There is opportunity for primary prevention.

JEFITHA DRKARIMURIO. "African Programme: Kenya Community Eye Health. 2000; 13 (36) : 53.". In: Community Eye Health. Korean Society of Crop Science and Springer; 2000. Abstract
Kenya is one of the East African countries with a coastline bordering the Indian Ocean and astride the equator. The country has an area of 225,000 square miles and a population of about 30 million people. The prevalence of blindness is estimated as 0.7%, with cataract contributing 43%, trachoma 19% and glaucoma 9%. The Kenya Ophthalmic Programme (KOP) is a Ministry of Health (MOH) programme receiving administrative support from the Kenya Society for the Blind (KSB). It started as a small project in 1956 but has grown into a major National Programme rendering comprehensive eye care (CEC) through a network of about 70 Government and NGO static and outreach service delivery points scattered all over the country. About half a million patients are treated annually.

Age changes in the aortic tunica intima may explain the higher prevalence of atherosclerosis among the elderly. Goat is a suitable model for the study of cardiovascular disease but the age changes in its aortic tunica intima are unreported. This study therefore examined structural changes that occur in the tunica intima of its aorta. Six healthy goats three aged over 60 months, and three aged less than 12 months, were used in this study. The animals were euthanized with sodium pentabarbitone and specimens taken from the various segment of the aorta studied by light microscopy and transmission electron microscopy. Materials for light microscopy were fixed 10% formaldehyde solution, processed for paraffin embedding and 7 micron sections stained with Mason’s Trichrome and Weigert’s Resorcin Fuchsin/Van Gieson stains. Those for transmission electron microscopy were fixed in 3% phosphate buffered glutaraldehyde solution, post fixed in osmium tetroxide and prepared for durcupan embedding. Ultrathin sections were stained with uranyl acetate, counterstained with lead citrate and examined by EM 201 phillips© electron microscope. Observations reveal that aging is characterized by endothelial discontinuities, presence of lymphocytes and dendritic cells in the tunica intima, subendothelial thickening, vacuolation and disintegration of internal elastic lamina. It is concluded that the intimal breaches observed in intimal aging may promote ingression of macromolecules into the vessel wall, and underpin the higher prevalence of atherosclerosis among the elderly. Control of serum atherogenic molecules should be enhanced in this age group.

Observations of the Magadi tilapia Alcolapia grahami in hot, highly alkaline Lake Magadi revealed that they air breathe not only during hypoxia, as described previously, but also during normoxia and hyperoxia. Air breathing under these latter conditions occurred within distinct groupings of fish (pods) and involved only a small proportion of the population. Air breathing properties (duration and frequency) were quantified from video footage. Air breathing within the population followed a diel pattern with the maximum extent of pod formation occurring in early afternoon. High levels of reactive oxygen species (ROS) in the water may be an irritant that encourages the air-breathing behaviour. The diel pattern of air breathing in the field and in experiments followed the diel pattern of ROS concentrations in the water which are amongst the highest reported in the literature (maximum daytime values of 2·53–8·10 μM H2O2). Interlamellar cell masses (ILCM) occurred between the gill lamellae of fish from the lagoon with highest ROS and highest oxygen levels, while fish from a normoxic lagoon with one third the ROS had little or no ILCM. This is the first record of air breathing in a facultative air-breathing fish in hyperoxic conditions and the first record of an ILCM in a cichlid species.
Key words: diel patterns; gill remodelling; interlamellar cell mass.

The report revisits the role of alcohol in the treatment of paroxysmal trigeminal neuralgia (PTN). The study included 6 patients, 3 male and 3 female, average age 50 years. In 3 cases PTN involved both the infraorbital and mental nerves; in 2 cases the infraorbital alone while one case had buccal branch involvement. In each case 2mls standard Lignocaine was infiltrated at each site followed by 2mls 60% sterile alcohol. All patients reported swelling postoperatively. One case with mental and infraorbital nerve involvement complained of oral dysaesthesia. Another patient with similar involvement failed to respond and developed trismus. Responders remained pain-free for 9 months on average. While paroxysmal trigeminal neuralgia (PTN) has been recognised for centuries, the aetiology and definitive treatment remain obscure. Since this is a debilitating condition, management should aim at improving the quality of life. Alcohol is available, affordable and offers useful results where medical resources provide limited PTN treatment modalities.

OBJECTIVE: To determine the pattern of occurrence of dental injuries in the 0-15 year-olds. DESIGN: A retrospective study. SETTING: Kenyatta National Hospital, Nairobi. SUBJECTS: Five hundred and five patient records with dental injuries were retrieved and analysed. RESULTS: A total of 505 patient records with dental injuries were retrieved and analysed. Most of the injuries were recorded in the year 1999 (22.2%). Boys were more affected (63.0%) than girls (37.0%). The main presenting complaint recorded was pain (75.8%).The majority of the patients (69.5%) presented for treatment during the same day or the day after trauma. Falls were the leading cause of injuries (73.5%). Most injuries involved two teeth (47.1%) and the maxillary central incisors were the most affected teeth both in the primary (67.5%) and permanent (64.0%) dentitions. Luxation injuries were the most common type of dental trauma with 47.5% occurring in the permanent teeth and 77.3% in the primary teeth. The main radiographic investigation performed was intraoral periapical views (52.9%) following which dental extraction (34.4%) was the main treatment modality offered. CONCLUSION: Prospective cross-sectional studies to determine the prevalence of dental injuries are needed. Furthermore improving the knowledge of dental practitioners through continuing dental education programmes would help in updating them on current trends in managing these injuries.

Measurements have been made of the leg muscles of mammals ranging from shrews Sorex to an elephant Loxodonta. Allometric equations based on body mass have been calculated for muscle masses, fibre lengths and moment arms and the thickness of a tendon, in several groups of mammals. Departures from geometric similarity in mammals in general (excluding bipedal hoppers) are noted and discussed. Differences between primates; fissipedes, bovids and bipedal hoppers are also demonstrated.

The principal bones, muscles and tendons of the legs have been measured in a selection of running birds, ranging in size from 0–1 kg quail to 40 kg ostrich. Maximum stride frequencies of the same species have been determined from films. Allometric equations have been derived. Most of the exponents agree well with McMahon's (1973, 1975a) theory of elastic similarity, which is discussed.

Although military conflicts are common on the African continent, there is a paucity of data regarding bomb-blast injuries in this region and in Kenya in particular. This paper describes the pattern of maxillofacial injuries sustained after the August 1998 bomb blast that occurred in Nairobi, Kenya. A retrospective cross-sectional study was carried out using hospital-based records of 290 bomb-blast survivors admitted at the Kenyatta National Referral and Teaching Hospital in Nairobi. Using a self-designed form to record information about variables such as the sex and age of the survivors and type of location of soft- and hard-tissue injuries, it was found that of the 290 bomb-blast survivors, 78% had sustained one or more maxillofacial injuries. Soft-tissue injuries (cuts, lacerations or bruises) were the most common, constituting 61.3% of all injuries in the maxillofacial region; 27.6% had severe eye injuries, while 1.4% had fractures in the cranio-facial region. This paper concludes that the effective management of bomb-blast injuries as well as those caused by other types of disaster requires a multidisciplinary approach. The high percentage of maxillofacial injuries confirm that maxillofacial surgeons should form an integral part of this multidisciplinary team.

Although the important role of the nonstructural (NS) gene of influenza A virus in virulence and replication is well-established, the knowledge about the extent of variation in the NS gene of 2009 influenza A (H1N1) viruses in Kenya and Africa is scanty. This study analysed the NS gene of 31 isolates from Kenya in order to obtain a more detailed knowledge about the genetic variation of NS gene of 2009 influenza A (H1N1) isolates from Kenya. A comparison with the vaccine strain and viruses isolated elsewhere in Africa was also made. The amino acid sequences of the non-structural protein, NS1 of the viruses from this study and the vaccine strain revealed 18 differences. Conversely, the nuclear export protein (NEP) of the isolates in this study had 11 differences from the vaccine strain. Analysis of the NS1 protein showed only one fixed amino acid change I123V which is one of the characteristics of clade 7 viruses. In the NEP, the amino acid at position 77 was the most mutable with 9 (39%) of all mutations seen in this protein. A mutation A115T which is a characteristic of clade 5 viruses was noted in the isolates from Lagos, Nigeria. The study shows a substantial number of mutations in the NS gene that has not been reported elsewhere and gives a glimpse of the evolution of this gene in the region.

J. A N-M, P.M M. "Anaesthesia in urinary tract disease.". 1990. Abstract

Surgical management of renal patients is a fascinating challenge requiring a detailed knowledge of anaesthetic techniques and a careful selection of the technique most compatible with each patient's condition. A knowledge of many facets of physiology, biochemistry and med icine that are influenced by urinary tract obstruction and renal dysfunction is paramount (Deutsch 1973). The function of the basic systems involved in homeostasis is generally impaired by anaesthesia. Therefore the degree of depression of renal haemodynarnics is inevitably of concem, especially so in anaesthesia of patients with urinary tract obstruction, or renal dysfunction (Bastron and Deutsch 1976; Deutsch 1973; Mazze and Cousins 1981). This paper deals with physiological, biochemical and medical factors that influence the action of anaesthetics in urinary tract disease, and thus affect the patient negatively. An insight is given on how to overcome some of these factors.

The level of inbreeding of the Kenya Alpine dairy goat was investigated by use of Brian Kinghorn’s Pedigree viewer© software. From 1,067 doe records, data on parentage was extracted and this resulted to 3,516 individual records that were used for calculating individual inbreeding coefficients for the period 1999 to 2009. The rate of inbreeding (ΔF) was estimated as the difference between the individual inbreeding (Ft) and the inbreeding of the parents (Ft-1) divided by (1-Ft-1). The proportion of animals that was inbred increased from 0.00 (average F = 0) in 1990 to 0.38 in 2009 (average F = 0.012). Inbreeding depression on body weight was significant (P<0.05). In general the level of inbreeding in this population was very low. Further investigation on the birth weight and weaning weight was carried out. Regression analysis indicated that birth weight (p<0.05) and weaning weight (p<0.01) had improved in inbreds. The decrease in weight at first service and at first kidding was statistically insignificant. Kidding interval increased (p<0.01) due to inbreeding. Rate of decline in weight at first service and at first kidding, was different from zero (p<0.01). Effect of inbreeding on growth and reproductive traits in Kenya Alpine goats was not very pronounced in the flock.

Ethnopharmacological relevance: Traditional medicines play an important role in the management of chronically painful and debilitating joint conditions, particularly in the rural Africa. However, their potential use as sources of medicines has not been fully exploited. The present study was carried to find the medicinal plants traditionally used to manage chronic joint pains in Machakos and Makueni counties in Kenya. Materials and methods: To obtain this ethnobotanical information, 30 consenting traditional herbal med-ical practitioners were interviewed exclusively on medicinal plant use in the management of chronic joint pains, in a pre-planned workshop. Results and discussion: In this survey, a total of 37 plants belonging to 32 genera and 23 families were cited as being important for treatment of chronic joint pains. The most commonly cited plant species were Pavetta crassipes K. Schum, Strychnos henningsii Gilg., Carissa spinarum L., Fagaropsis hildebrandtii (Engl.) Milve-Redh. and Zanthoxylum chalybeum Engl. Acacia mellifera (Vahl) Benth., Amaranthus albus L., Balanites glabra Mildbr. & Schltr., Grewia fallax K. Schum., Lactuca capensis, Launaea cornuta (Oliv. & Hiern) O. Jeffrey, Lippia kituiensis Vatke, Pappea capensis Eckl. & Zeyh. and Pennisetum glaucum (L.) R. Br. are documented for the first time as being important in the management of chronic joint pains. Conclusions: The findings of this study show that a variety of medicinal plants are used in the management of chronic joint pains and the main mode of administration is oral.

This paper analyzes the socio-economic characteristics of households that affect husbands and wives' contributions to decisions regarding the use of income from crop and livestock sales in Kenya. Using a sample of 276 households, we apply a multinomial logit model to assess factors affecting decision-making. Results show that husbands make most decisions concerning agriculture, while wives mainly decide on daily household expenditure. Higher education levels were found to increase women's involvement in decision-making on income use. Group membership had a positive effect on joint decision-making on income use. The study recommends improving women's access to education, which will improve their access to productive resources, hence their decision-making power. Providing incentives for members of agricultural groups can provide avenues for learning. Gender-transformative approaches that empower women and sensitize men to allow space for women to engage in decision-making, can have an impact in improving the decision-making capacity of women in households.

The decision to pay out earnings or retain dividends has been a subject of debate for many scholars. The effect of dividend on the firm value and cost of capital have been covered in attempt to resolve the dividend puzzle. This research paper tests the applicability of constant dividend model by companies listed at the Nairobi stock exchange. Data was collected from annual reports and share price schedules obtained from Nairobi stock exchange and Capital market Authority for a population of 20 companies that paid dividends consistently from 2002 to 2008. The data was then analyzed by re-computing the dividends that should have been paid if the dividend constant model was applied. This recomputed figure was later compared to the dividend as paid out by the companies thought the years of study. Paired sample t-test statistic was also performed to determine whether there is a significant difference between the two dividend figures. The findings of the research established that the dividend model was not employed by the companies listed at the Nairobi stock exchange. Most firms instead adopted stable and predictable policy where a specific amount of dividend per share each year was paid periodically. In some years there was a slight adjustment of the dividend paid after an increase in earnings, but only by a sustainable amount. The study shows that the relationship between the stock market prices and the dividend paid from the constant dividend model is uneven from one year to another and where there was a relationship it was insignificant. Though a share would be highly priced, a high dividend per share was not always declared.

Introduction Knowledge of anatomical variations in the origin and in the course of the dorsal metatarsal arteries (DMTAs) is valuable for many procedures, including reconstructive surgeries and flap selection. However, there is a paucity of data on these arteries among black Africans. Materials and Methods The present study studied the origin and the location of DMTAs in 30 formalin-fixed cadaveric feet of adult black Kenyans at the Department of Human Anatomy of the University of Nairobi, Nairobi, Kenya. Results Dorsal metatarsal arteries were present in all of the cases. Of the right dorsalis pedis artery (DPA), in the majority of the cases, the 1st DMTA arose as the continuation of the DPA, while the 2nd to 4th DMTAs were given off as branches from the arcuate artery (AA). On the left feet, in the majority of the cases, the 1st DMTA arose as the continuation of the DPA, while the rest were given off as branches from the AA. In relation to the dorsal interossei muscles, all of the the arteries were either within the muscle fibers (53%) or beneath them (47%), on the right side. On the left side, the 1st DMTA was above the muscles in 40% of the cases; within the muscles in 53%; and beneath the muscles in 7%. The 2nd and 3rd DMTAs were above the muscles in 57% and in 53% of the cases, respectively. Conclusion These results reveal that the DMTAs show variation in their origin and position relative to the dorsal interossei muscles. These variations display bilateral asymmetry.

Background: Prolapsed intervertebral disk (PID) disease can be managed conservatively or surgically with different reported outcomes.Objective: The present study aimed at assessing the management and outcomes of slipped intervertebral disk disease at the Kenyatta National hospital.Study Design: A retrospective cross-sectional study.Setting: Kenyatta National Hospital (KNH) a referral and teaching Hospital in Kenya.Patients and Methods: Consecutive files of all cases of slipped intervertebral disk disease from January1997 to December 2007 were retrieved from the Medical records at the Kenyatta National Hospital. The biodata, management methods and the outcomes of the procedures were recorded. The collecteddata was analyzed using the SPSS 17.0 for Windows.Results: Six hundred and three cases were reviewed. All patients received analgesics and bed rest.Five percent of the patients were put on bilateral traction for two weeks while 4% of the patients had corsets. Thirty five per cent of the patients were surgically managed. Over a third of the surgically managed patients had laminectomies. Microdiscectomy was increasingly popular in the latter half ofthe study period. Of the managed patients 95% reported improvement while 92% were complication free. The rate of reherniation and reoperation was 1.5% and 1.2% respectively.Conclusion: The management of PID at Kenyatta National Hospital is largely successful with few cases of complications. In selected patients both conservative and surgical care are used in tandem. Microdiscectomy is an increasingly popular surgical procedure at the KNH.

Background: Anatomical variations of lumbar arteries predispose them to iatrogenic injury during endovascular intervention or surgery. Due to limited morphological data on lumbar arteries in our setting, we aimed to determine their variant anatomy among Kenyans.

Methods: We performed the study on 90 cadaveric specimens and 120 computed tomography (CT) scans. Cadavers were dissected to expose the aorta and the lumbar arteries emerging from them. The number, origins, location relative to the vertebral bodies, and relations to aortic bifurcation were determined in cadavers and CT scans. Data were analyzed using SPSS (version 21.0).

Results: On average, 3 (3/90 [3.3%]), 4 (63/90 [70%]) or 5 (24/90 [26.7%]) pairs of lumbar arteries were observed among the cadaveric specimens, whereas 4 (100/120 [83.3%]) or 5 (20/120 [16.7%]) pairs were observed in CTs. Differences in the number of pairs observed in the cadaveric versus CT study were not statistically significant (P = .542). There were no sex differences in the number of lumbar artery pairs observed in CT scans (P = .178). The first 3 lumbar artery pairs had a single-origin, whereas the fourth lumbar artery had a common-stem origin. The first, second, and third lumbar arteries mostly originated at the upper third of their respective vertebral bodies. The fourth lumbar artery predominantly originated at the lower third.

Conclusion: Our study's findings show unique variation in the lumbar arteries' relation to the vertebral bodies and the distances between artery pairs.

Level of evidence: IV (cross-sectional study).

Clinical relevance: Variations in the anatomy of the lumbar arteries should be taken into consideration, especially in surgical or interventional procedures to avoid inadvertent injury of the vessels.

We present an online anatomy atlas based on the Visible Human Project (VHP) of the US National Library of Medicine. The objective is to provide original unlabeled as well as labeled sections of the human body of high quality and resolution on the Internet, for use in basic and continuing medical education. For a representative overview of the body, 370 axial sections were selected from the male and female data base of the VHP with special regard to regions of clinical interest. Each section is accompanied by its corresponding computer tomography (CT) image and, if available, magnetic resonance images (MRI) for quick and easy comparison of morphologic and radiologic structures. The sections can be studied unlabeled or labeled according to the current Terminologia Anatomica. A linked vocabulary with more than 850 terms explains the labeling. Animations of the sections as well as of CT and MR images allow for further visualization of the topographic relationships of anatomical structures. The responses to the project indicate that students and physicians regard the Internet Atlas of Human Gross Anatomy as a most useful aid for learning and reviewing anatomical details. The atlas is accessible on: http://www.uni-mainz.de/FB/Medizin/Anatomie/workshop/vishuman/Eready.html.

"Anchored vs. relative best-worst scaling and latent class vs. hierarchical Bayesian analysis of best-worst choice data: Investigating the importance of food quality attributes in a developing country.". In: Food Quality and Preference. The Kenya Medical Association; 2012. Abstract
The effect of acqueous extract of the tuber of Adenia globosa on the isolated preparation of the rat uterus was determined. The crude drug caused a dose-dependent contraction of the tissue preparation. This action was enhanced by a small dose of oxytocin. The results are discussed in relation to the traditional uses of this plant.

Applying best–worst (BW) scaling to a multifaceted feature, e.g. food quality, is challenging as attribute non-attendance or lack of attribute discrimination risks invalidating the transformation of choice data to unidimensional scale. The relativism of BW scaling also typically prevents distinction of respondents or groups of respondents based on similarities to the study object. A dual-response BW scaling method employed here to obtain an anchored scale allowed comparisons of importance ratings across individuals. Attribute importance ratings and rankings obtained were compared with those from relative BW scaling. Latent class (LC) and hierarchical Bayesian (HB) analyses of individual specific BW choice data were also compared for ability to consider within- and between-respondent choice heterogeneity. Personal interviews with 449 consumers provided data on the importance of 16 food quality attributes of kale produced in peri-urban farming in Kenya. Major findings were that the anchoring model improved individual choice predictions compared with conventional relativistic BW scaling, i.e. was more reliable in measuring consumer preferences, and that HB analysis fitted the data better than LC analysis. HB analysis also successfully obtained individual parameter estimates from sparse data and is thus a promising tool for analysis of BW choices in sensory and consumer-orientated research.

One-dimensional atomic chains can be synthesized on stepped surfaces and the electronic
structure of the high vicinal surface plays an essential role in determining the physical
properties of atomic chains grown on top of it. We have applied surface analysis techniques
to study the surface of a Pt (997) single crystal. The STM image of the surface showed that
the surface was uniform with a well defined distance between the terraces. Angle resolved
photoemission spectroscopy (ARPES) was used to characterize the electronic states of …

Abstract. A study was conducted in which samples ol soil. forage, as well as serum, bone, kidney, and liver of waterbuck were collected from Lake Nakuru National Park. The objective was to determine the ecosystem health status in older to establish the causes of animal health problems previously re¬corded in some sections of the Paik. Trace element analysis in serum indicated occurrence ol copper (Cu) deficiency in the north and eastern sections of the Park where mean values were marginal (range: 0.36-0.81. mean: 0.62 mg/1) compared to concentrations recorded in the western part of the Park (range: 0.69 1.48. mean: 1.22 mg/l). Bone analysis on dry matter basis (DM) indicated higher (p < 0.01) levels of cadmium (Cd. 0.437 nig/kg), fhioride (F, 3178 mg/kg). and lead (Pb. 20.62 mg/kg) in animals from the east compared to those from the west (0.002. 1492, 4.87 mg/kg. respectively), suggesting heavy exposure. In addition, samples from the east had much lower than normal calcium (Ca)-to-phosphorus (P) ratios (mean: 1.9:1) compared to those recorded in the west (2.2:1). suggesting poor bone minerali/ation There was a higher concentration of Cd in the kidney (16.24 mg/kg. p < 0.05) and Pb in the liver (58.3 mg/kg. /; < 0.01) in animals from the east compared to those in the west (12.92 and 36.2 mg/kg, respectively), but the converse was true of Cu The liver Cu status was better in animals from the west with, concentrations (mean: 21.7 mg/kg) being about twice those recorded in the east (11.9 mg/kg DM). Forage analysis revealed prospects of Ca, P, and Cu deficiencies in the entire Park. However, in the northeastern section of the Park (measuring 50 ha) where waterbuck residence times are high, forage concentrations of Cd (0.31 mg/kg DM), molybdenum (Mo. 7.20 mg/kg DM). Pb (2.88 mg/kg DM), and /inc (7.n. 126 mg/kg DM) were an order of magnitude greater (p < 0.01) than the levels recorded in the rest of the Park (ranges: 0.133 0.165, 3.69 5.61. 0.485 0.621. 11.6 17.4 mg/kg DM, respectively). These disparities were attributed to a higher soil concentration of CM (2.77 mu/ku DM). Pb (85.1 msi/k DM) and 7,n (1414mg/kg DM i n this section compared lo the rest of the Park (ranges; 0 Id o 15. 5.02 6.26. 1,49 5.44 mg/kg DM. respec¬tively), and su»ngly suggest heavy metal contamination as the source ol annual health problems in the Park.

"Antenatal corticosteroids for women at risk of imminent preterm birth in low-resource countries: the case for equipoise and the need for efficacy trials." British Medical Journal Global Health. 2017;2(3). AbstractWebsite

The scientific basis for antenatal corticosteroids (ACS) for women at risk of preterm birth has rapidly changed in recent years. Two landmark trials-the Antenatal Corticosteroid Trial and the Antenatal Late Preterm Steroids Trial-have challenged the long-held assumptions on the comparative health benefits and harms regarding the use of ACS for preterm birth across all levels of care and contexts, including resource-limited settings. Researchers, clinicians, programme managers, policymakers and donors working in low-income and middle-income countries now face challenging questions of whether, where and how ACS can be used to optimise outcomes for both women and preterm newborns. In this article, we briefly present an appraisal of the current evidence around ACS, how these findings informed WHO's current recommendations on ACS use, and the knowledge gaps that have emerged in the light of new trial evidence. Critical considerations in the generalisability of the available evidence demonstrate that a true state of clinical equipoise exists for this treatment option in low-resource settings. An expert group convened by WHO concluded that there is a clear need for more efficacy trials of ACS in these settings to inform clinical practice.

To determine effect of partner involvement and couple counseling on uptake of interventions to prevent HIV-1 transmission, women attending a Nairobi antenatal clinic were encouraged to return with partners for voluntary HIV-1 counseling and testing (VCT) and offered individual or couple posttest counseling. Nevirapine was provided to HIV-1-seropositive women and condoms distributed to all participants. Among 2104 women accepting testing, 308 (15%) had partners participate in VCT, of whom 116 (38%) were couple counseled. Thirty-two (10%) of 314 HIV-1-seropositive women came with partners for VCT; these women were 3-fold more likely to return for nevirapine (P = 0.02) and to report administering nevirapine at delivery (P = 0.009). Nevirapine use was reported by 88% of HIV-infected women who were couple counseled, 67% whose partners came but were not couple counseled, and 45%whose partners did not present for VCT (P for trend = 0.006). HIV-1-seropositive women receiving couple counseling were 5-fold more likely to avoid breast-feeding (P = 0.03) compared with those counseled individually. Partner notification of HIV-1-positive results was reported by 138 women (64%) and was associated with 4-fold greater likelihood of condom use (P = 0.004). Partner participation in VCT and couple counseling increased uptake of nevirapine and formula feeding. Antenatal couple counseling may be a useful strategy to promote HIV-1 prevention interventions.

The removal of deciduous canine tooth buds in early childhood is a practice that has been documented in Kenya and in neighboring countries. This paper describes the occurrence, rationale and method of this practice amongst rural Kenyan Maasai. In a group of 95 children aged between six months and two years, who were examined in 1991/92, 87% were found to have undergone the removal of one or more deciduous canine tooth buds. In an older age group (3-7 years of age), 72% of the 111 children examined exhibited missing mandibular or maxillary deciduous canines. It was found that the actual removal of a deciduous tooth bud is often performed by middle-aged Maasai women who enucleate the developing tooth using a pointed pen-knife. There exists a strong belief among the Maasai that diarrhoea, vomiting and other febrile illnesses of early childhood are caused by the gingival swelling over the canine region, and which is thought to contain 'worms' or 'nylon' teeth. The immediate and long-term hazards of this practice include profuse bleeding, infection and damage to the developing permanent canines. A multi-disciplinary approach involving social anthropologists in addition to dental and medical personnel, is recommend in order to discourage this harmful operation that appears to be on the increase.
