" 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.

Odada E, Zalasiewicz J, Williams M, Waters CN, Barnosky AD, et al. " Scale and diversity of the physical technosphere: A geological perspective." The Anthropocene Review. 2017;4(1):9-22. AbstractFull Text

We assess the scale and extent of the physical technosphere, defined here as the summed material output of the contemporary human enterprise. It includes active urban, agricultural and marine components, used to sustain energy and material flow for current human life, and a growing residue layer, currently only in small part recycled back into the active component. Preliminary estimates suggest a technosphere mass of approximately 30 trillion tonnes (Tt), which helps support a human biomass that, despite recent growth, is ~5 orders of magnitude smaller. The physical technosphere includes a large, rapidly growing diversity of complex objects that are potential trace fossils or ‘technofossils’. If assessed on palaeontological criteria, technofossil diversity already exceeds known estimates of biological diversity as measured by richness, far exceeds recognized fossil diversity, and may exceed total biological diversity through Earth’s history. The rapid transformation of much of Earth’s surface mass into the technosphere and its myriad components underscores the novelty of the current planetary transformation.

Isolated mouse interstitial cells were incubated with different concentrations of khat (Catha edulis) extract (0.06 mg/ml, 0.6 mg/ml. 6 mg/ml. 30 mg/ml and 60 mg/ml) and cell viability as well as testosterone concentration measured at 30 min intervals over a 3 h incubation period. High concentrations of khat extract (30 mg/ml and 60 mg/ml) significantly inhibited testosterone production while low concentrations (0.06 mg/ml. 0.6 mg/ml and 6 mg/ml) significantly stimulated (P < 0.05) testosterone production by mouse interstitial cells. Similarly, at concentrations of 30 mg/ml and 60 mg/ml, there was a significant decrease in interstitial cell viability, whereas at 0.06 mg/ml, 0.6 mg/ml and 6 mg/ml there was no significant decrease. There was only a weak correlation (r= 0.39) between testosterone production and viable interstitial cells. We postulate that khat extract at high concentrations may cause reproductive function impairment in the user but at low concentrations. may enhance testosterone production with accompanying effects on reproductive functions in male mice. @2006 Publishedby Elsevier Ireland Ltd.

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.

Department of Orthopaedic Surgery, College of Health Sciences, University of Nairobi, Kenya. A case report is presented of a 53 year old man who presented with posterior dislocation of the hip after a road traffic accident. Initial management by closed reduction failed due to presence of an occult free intra-articular fragment. This fragment was not visualised on plain A-P and lateral X-ray views. The cause of the failed closed reduction was eventually detected by CT scan. Open reduction and removal of the bone fragment was done and the hip remained stable thereafter. It is concluded that plain X-rays are not adequate in the diagnosis of free intra-articular bone fragments within the hip joint and CT scanning is advised for accurate detection of such occult bine fragments.

The purpose of this study was to investigate how school characteristics affect the usage of the PM and the consequent impact on learner achievement in physics (LAP). Data was collected using Students Achievement Tests (SAT) and questionnaire for physics teachers. Stratified Sampling was applied to select 84 schools comprising boys, girls and mixed schools from seven provinces of Kenya. Statistical Package for Social Sciences (SPSS) was used to analyze the data. ANOVA, chi-square and multiple-regression were used to test the hypothesis. The key findings of the study were that PM enhances the learning of physics; Single sex schools performed better than mixed schools; the type of schools in terms of gender, whether day or boarding were not factors in the usage of project method. In view of these research findings, the researchers recommend that the government come up with a policy that enhances the establishment of more single sex schools, enhance resource mobilization for the teaching of physics, review the teacher training component so as to encompass the PM as an alternative teaching strategy, and in-service physics teachers on the role of school characteristics in the study of physics.

Background: The diversity of benign jaw tumours may cause difficulty in a correct diagnosis and insti-tution of an appropriate treatment. Data on the prevalence of these tumours is scarce from the Afri-can continent. We present a 19-year audit of benign jaw tumours and tumour-like lesions at a University teaching hospital in Nairobi, Kenya. Methods: Histo-pathological records were retrieved and re-examined from the Department of Oral and Maxillofacial pa-thology, University of Nairobi from 1992 to 2011. The jaw tumours were classified according to the latest WHO classification. Results: During the 19-year audit, 4257 biopsies were processed of which 597 (14.02%) were jaw tumours within an age range of between 4 to 86 years. There was greater number of odontogenic tumours 417 (69.85%) than the bone related lesions 180 (30.15%). Of the odontogenic tumours, the epithet- lial and in the bone related types, the fibro-osseous lesions were frequent. Conclusion: Ameloblastoma and ossifying fibroma were the most frequent tumours reported in this audit. The information regarding the prevalence of these tumours is scarce from the conti-nent and can be useful in early detection and man-agement before they cause facial deformity.

WANJIRU. DRGITARIPATRICIA. "2, 2.". In: Acta Crystallographica C. International Union of Crystallography; 2004. Abstract
Presented here is a 16-year-old girl who was referred on 30th January 1996 with diagnosis of cord compression with spastic paraplegia with sensory level at T7/T8. CT scan myelogam confirmed soft tissue density mass displacing cord to the left with no dye being seen beyond T3. Thoracic spine decompressive laminectomy was performed on 1st January 1996 at Nairobi West Hospital extending from T3 to T6 level, which revealed a fibrous haemorrhagic tumour. Histology showed meningioma (mixed fibrous type and meningoepitheliomatous type) with many psammoma bodies. She had a stormy post-operative period, with infection and wound dehiscence. This was treated with appropriate antibiotics and wound care. She was eventually rehabilitated and was able to walk with the aid of a walking frame because of persistent spasticity of right leg. She was seen once as an outpatient by author on 6th July 1996, she was able to use the walking frame, but the right leg was still held in flexion deformity at the knee. She was thus referred to an orthopaedic surgeon for possible tenotomy. She was able to resume her studies at the University ambulating using a wheel chair and walking frame. She presented with worsening of symptoms in 2001 (five years after her first surgery). MRI scan thoracic spine revealed a left anterolateral intradural lesion extending from T3 to T5 vertebral body level compressing and displacing the spinal cord. She had a repeat surgery on 6th March 2001 at Kenyatta National Hospital; spastic paraparesis and urinary incontinenece persisted. She also developed bed sores and recurrent urinary tract infections. She was followed up by the author and other medical personnel in Mwea Mission Hospital where she eventually succumbed in 2005, nine years after her first surgery. This case is presented as a case of incompletely excised spinal meningioma to highlight some of the problems of managing spinal meningiomas when operating microscope and embolisation of tumours are not readily available. Also the family experienced financial constraint in bringing the patient for regular follow-up, and getting access to appropriate antibiotics, catheters and urine bags.

In a case of poisoning involving 70 cattle analysis of specimens obtained during post mortem examination showed that the toxic substances were arsenic and toxaphene. This was consistent with both the clinical and post mortem findings. Arsenic was detected in water from an abandoned cattle dip in the farm. Soil samples collected in the vicinity of the dip contained both arsenic and toxaphene.

In a case of poisoning involving 70 cattle analysis of specimens obtained during post mortem examination showed that the toxic substances were arsenic and toxaphene. This was consistent with both the clinical and post mortem findings. Arsenic was detected in water from an abandoned cattle dip in the farm. Soil samples collected in the vicinity of the dip contained both arsenic and toxaphene.

Persons with congenital or acquired immunosuppression have long been known to have an increased incidence of lymphoproliferative disorders. Unsurprisingly, therefore, the acquired immunodeficiency syndrome (AIDS), caused by the human immunodeficiency virus (HIV), is associated with an increased incidence of lymphoma. Three cases with HIV-associated lymphoma aged 30, 32 and 35 years respectively are presented. Two had cutaneous non-Hodgkin's lymphoma while one had Hodgkin's lymphoma. Standard chemotherapy for lymphoma was given with good tumour regression. Two of the patients died within six months of lymphoma diagnosis due to other complications of HIV.

Background: Dental and cranio-maxillofacial diagnostic imaging constitutes an invaluable tool in the accurate diagnosis and management of a diverse range of conditions and diseases that afflict the oral and cranio-maxillofacial region. In order to improve on any existing facility, periodic audit evaluation is paramount. In this way proper and relevant service delivery can be achieved. Objective: To evaluate the range and volume of dental and cranio-maxillofacial diagnostic radiographic services offered at the University of Nairobi Dental Hospital (UNDH) in Kenya over a 5-year period (2006-2010). Methods: Retrospective survey involving manual examination of patient records at the Division of Dental and cranio-maxillo- facial Radiology registry of the UNDH. Results: Over the study period, the range of diagnostic radiographic services offered comprised of both intra- and extra- oral examinations. The total volume of radiographs taken was 48,874 among which 41,980 (86%) were intraoral and 6894 (14%) extraoral views. Among the intraoral views, 74% were bitewing, 25% periapical and only 1% were occlusal diagnostic views. The majority (95%) of the extraoral projections consisted of panoramic views and only 5% constituted other techniques. The volume of radiographs was high from January to September while November and December had the lowest number of examination requests. Conclusion: Intraoral radiography was the commonest examination with bitewings having been the majority while the panoramic tomography was the com- monest extraoral examination performed.

Here we outline the basis on which a formal proposal should be made for potential inclusion of the Anthropocene in the Geological Time Scale, examining the scale and rate of human change to the Earth System to help recognise the point at which anthropogenic impacts became of sufficient scale to allow discrimination of the Anthropocene as a geological unit. This examination covers such factors as impacts from early hominin species, the first human artefacts, early ecosystem modification through agriculture, deforestation, the domestication of animals, urbanisation, metal mining and smelting and early globalisation. The Industrial Revolution, starting in the UK in the 18th century, and the global Great Acceleration of the mid-20th century, are investigated, as both provide popular narratives that explain the Earth System changes indicative of the Anthropocene, with the latter producing the near-synchronous stratigraphic signals most consistent with an effective geological time boundary. We assess which hierarchical level–age, epoch, period, era or eon–seems most suitable for the Anthropocene, and suggest that epoch (= series) level is conservative and appropriate. The Anthropocene might be defined via a Global Standard Stratigraphic Age or a Global boundary Stratotype Section and Point, with the latter being most appropriate. Finally, we assess the kinds of geological environments, including anoxic marine basins, annually banded coral and bivalve skeletons, estuaries and deltas, lake floors, peat mires, anthropogenic deposits, polar ice, speleothems and tree rings, in which such a physical reference level might be placed.

In: Kenya Journal of Sciences, Series C., Social Sciences, of the Kenya National Academy of Sciences Vol. 1. Elsevier; 1988. Abstract

Settlement pattern studies are concerned with relics of human occupation in the past. In an archaeological record, these relics either appear in clusters or individually in the form of pestholes, house floors, house foundations or as middens. On aerial photographs and topographic maps relics of past human occupation can be identified by the presence of circular or rectangular depressional features and stunted vegetation cover in the midst of a flourishing vegetation community. Past human settlements can also be identified in actual field observation as ruins: building structures, walled fortresses, moats, monuments and mounds.

Irrespective of their nature and conditions of preservation, past settlements are a reflection of human behaviour through time and space. The archaeological evidence that is found preserved in them can shed much light on our knowledge of past culture. The essential archaeological problem in the analysis and interpretation of settlement, however, is that architectural remains and other settlement data cannot be understood simply by their description, distribution, cultural attribution and chronology - as they have been from the early anthropological work of Morgan (1881) and Mindeleff (1890) through the first large-scale regional archaeological syntheses, such as Childe's (e.g. 1934) in Europe and Willey (1953) in South America up to the common archaeological survey work of today.

With the influence of modern cultural ecology, geography and sociobiology, settle­ment analysis has been transformed into a concern with environmental and ecological processes. Settlements are part of a complex integration of culture and ecology within a regional environment. As a result, settlement analysis in archaeology must attend not only to the physical layout of the environment, but also to the social and historical aspects of environmental interaction.

Participatory rural appraisal techniques and a survey of 100 households were used to evaluate livestock production, and pastoral development of the Maasai in Mara. It was observed that patterns of land-use have principally changed from nomadic pastoralism to sedentary pastoralism, agropastoralism, and, in some cases, pure cultivation. These trends have adversely affected livestock production and the productive capacity of the Mara ecosystem. Diminishing grazing area occasioned by expanding cropping patterns has negatively impacted on vegetation resources and the biodiversity of the ecosystem. It has also increased the intensity of conflict over diminishing land resources. Because the production system is largely subsistence with a strong livestock base, it is further undermined by, among other factors, animal diseases, water scarcity, land individualisation, poor marketing infrastructure, and livestock/wildlife conflicts. Based on the findings of the present study, development approaches need to emphasize integrated livestock and wildlife utilization, land tenure reforms that embody livestock mobility as a key strategy of optimising the use of transient forage resources, disease control, and development of livestock marketing.

Genetic diversity of 50 Phaeoisariopsis griseola isolates collected from different agro ecological zones in Kenya were studied using group specific primers and amplified fragment length polymorphism (AFLP) markers. Group-specific primers differentiated the isolates into Andean and Mesoamerican groups, corresponding to the two common-bean gene pools. Significant polymorphisms were observed with all the AFLP primer combinations used, reflecting a wide genetic diversity in the P. griseola population. A total of 207 finger prints was generated, of which 178 were polymorphic. Cluster analysis of the polymorphic bands also separated the isolates into the two groups defined by group specific primers. All the isolates examined were grouped into three virulence populations; Andean, Afro-Andean and Mesoamerican, and their genetic diversity measured. On average, greater diversity (91%) was detected within populations than between populations (9%). The genetic distance between Andean and Mesoamerican populations was higher (D = 0.0269) than between Andean and Afro-Andean (D = 0.0095). The wide genetic diversity reported here has significant implications in breeding for resistance -to angular leaf spot and should be taken into consideration when screening and deploying resistant bean genotypes.

Fusarium wilt caused by Fusarium udum Butler, is an economically important disease of pigeonpea (Cajanus cajan (L.) Mill). Information on the mechanisms of resistance to this disease in pigeonpea is limited. To study the role of vascular occlusion in wilt resistance, isolates of F.udum were inoculated onto resistant and susceptible varieties of pigeonpea and observed under light and transmission electron microscopes. The presence of F. udum in wilt susceptible plants was characterized by mycelia and conidia in the xylem vessels, plugging in some vessels, disintegration of xylem parenchyma cells in the infected areas, and the formation of cavities due to heavy colonization in the pith cortex vascular bundle. Resistance to F. udum in the roots and stems of wilt resistant plants was associated with low fungal colonization and high occlusion due to tyloses and gels in the xylem vessels. There were significant differences (P = 0:05) in the number of xylem vessels occluded by tyloses in resistant and susceptible plants with a maximum of 22.5% and 8.0% occlusion, respectively. It is probable that tyloses and gels formed as a result of F. udum interaction in wilt resistant plants are part of a resistance mechanism.

Department of Infectious Disease Epidemiology, Imperial College School of Medicine, London, UK. Previous attempts to determine the interactions between filariasis transmission intensity, infection and chronic disease have been limited by a lack of a theoretical framework that allows the explicit examination of mechanisms that may link these variables at the community level. Here, we show how deterministic mathematical models, in conjunction with analyses of standardized field data from communities with varying parasite transmission intensities, can provide a particularly powerful framework for investigating this topic. These models were based on adult worm population dynamics, worm initiated chronic disease and two major forms of acquired immunity (larval- versus adult-worm generated) explicitly linked to community transmission intensity as measured by the Annual Transmission Potential (ATP). They were then fitted to data from low, moderate and moderately high transmission communities from East Africa to determine the mechanistic relationships between transmission, infection and observed filarial morbidity. The results indicate a profound effect of transmission intensity on patent infection and chronic disease, and on the generation and impact of immunity on these variables. For infection, the analysis indicates that in areas of higher parasite transmission, community-specific microfilarial rates may increase proportionately with transmission intensity until moderated by the generation of herd immunity. This supports recent suggestions that acquired immunity in filariasis is transmission driven and may be significant only in areas of high transmission. In East Africa, this transmission threshold is likely to be higher than an ATP of at least 100. A new finding from the analysis of the disease data is that per capita worm pathogenicity could increase with transmission intensity such that the prevalences of both hydrocele and lymphoedema, even without immunopathological involvement, may increase disproportionately with transmission intensity. For lymphoedema, this rise may be further accelerated with the onset of immunopathology. An intriguing finding is that there may be at least two types of immunity operating in filariasis: one implicated in anti-infection immunity and generated by past experience of adult worms, the other involved in immune-mediated pathology and based on cumulative experience of infective larvae. If confirmed, these findings have important implications for the new global initiative to achieve control of this disease.

Objective: To determine the pattern of breast disease at Kenyatta National Hospital (KNH) Study design:    Retrospective descriptive study Study setting:    Kenyatta National Hospital, a University teaching and National Referral Hospital Patients: Records of 1172 patients were reviewed. Results: An average 469 new patients per year or 11 new patients per clinic visit were seen at the clinic over a two and a half year period. Females predominated (98.9%) in this series. The mean age was 34.71 years (range 1 to 96 years). The average age at menarche was 14.49 years and the mean duration of symptoms was 6.86 months. Only 2.6% of 843 patients had a positive family history of breast disease. Fibroadenoma was the commonest diagnosis made (33.2%) followed by ductal carcinoma (19.7%). Gynaecomastia was the most common lesion seen in males. Two thirds of patients presenting with tumors had masses measuring more than 5cm.  Overall five conditions (fibroadenoma, ductal carcinoma, breast abscesses, fibrocystic disease and mastalgia) accounted for over 85% of all breast ailments. Surgery formed the main stay of care in over 80% of patients. Conclusions: The pattern of breast diseases at KNH closely mirrors those reported in other studies in the region and beyond. This study indicates that a large proportion of patients presenting with breast disease are treated initially by surgery. It may be wise to consider other alternative forms of therapy where appropriate. The Annals of African Surgery: 2008 June; Vol 2, pg 97-101.

In Kenya the reported high rates of unwanted pregnancies (more than 90%), among adolescents have subsequently resulted in unsafely induced abortions with the associated high morbidity and mortality rates.
To evaluate the adolescents' behaviour regarding induced abortion.
A cross-sectional, prospective study done from July 1995 to June 1996.
Schools and health facilities in Kiambu and Nairobi districts in Kenya.
Interviews were conducted among adolescents aged 10-19 years in schools at the two districts and selected using a multi-stage random sampling procedure, as well as adolescent girls at two hospitals and two clinics in the immediate post-abortion period.
The number of adolescents health programmes, aimed at reducing the dangers of unsafely induced abortion, which are designed and subsequently implemented.
Demographic and health data, as well as data on behaviour regarding induced abortion were collected using a self-administered questionnaire.
The study sample comprised 1820 adolescents. These were 1048 school girls (SG), 580 school boys (SB) and 192 post-abortion (PA). Many adolescents were aware of abortion dangers, with the awareness being significantly lower among the SB whose girlfriends (GF) had aborted than those whose GF had not (p < 0.01). The practice of abortion was reported among 3.4% SG, 9.3% SBs' GF and 100% PA. Direct and indirect costs of abortion were heavy on the girls. Knowledge of the abortion dangers had no influence on the choice of the abortionist. Abortion encounter positively influenced approval by the adolescents, of abortion for pregnant school girls (p < 0.01).
Despite the costs and awareness of abortion dangers by adolescents, they will take risks

Pregnancy among adolescents is unplanned in many instances. Although some pregnant adolescents carry the pregnancy to term, abortion, in many instances unsafely induced, is a commonly sought solution in Kenya.
OBJECTIVE:
To determine adolescents' perceptions of induced abortion.
DESIGN:
A cross-sectional descriptive study carried out between July 1995 and June 1996.
SETTING:
An urban and a rural district in Kenya.
PARTICIPANTS:
Adolescents aged 10-19 years in schools in Nairobi and Kiambu districts, and a group of immediate post-abortion adolescent girls in some health facilities in Nairobi.
MAIN OUTCOME MEASURES:
The number of health programmes formulated and put into use, which are adolescent-friendly and providing information, education and communication on abortion issues.
DATA COLLECTION:
One thousand eight hundred and twenty adolescents were subjected to a self-administered questionnaire that collected demographic and health data as well as perceptions of induced abortion. Focus group discussions on perceptions of abortion were held with 12 groups of adolescents in schools and the information obtained recorded on paper and in a tape-recorder.
RESULTS:
One thousand nine hundred and fifty two adolescents, comprising of 1048 school girls (SG), 580 boys (SB), 192 post-abortion girls (PA) and 132 adolescents in the focus group discussions, formed the study sample. More than 90% were aware of induced abortion (IA). Knowledge of IA correlated positively with level of education (P < 0.01). Seventy one per cent of SG, 84% of PA and 40% of SB were aware of abortion-related complications, the most common being infections, death and infertility. Eighty three per cent of PA felt that complications were preventable by seeking care from a qualified doctor compared to one quarter each for the SB and SG. 56% PA, 69% SB and 72% SG felt that abortions were preventable. However, less than 40% proposed abstinence as a primary strategy. The most important source of information on abortion was the media followed by friends and teachers.
CONCLUSION:
Adolescents are aware of abortion and the related complications, but there is more variability in their knowledge and preventive measures.

Waweru SE, Meme JS, Kinuthia DM, Kitonyi GW. "Absence of HIV seropositivity in children with sickle cell anaemia at Kenyatta National Hospital, Nairobi, Kenya.". 1987. AbstractWebsite

OBJECTIVE: To find out whether frequent blood transfusions increase the risk of transfusion-related HIV infection in children with Sickle cell anaemia. METHODS: One hundred and ninety-eight children with Sickle cell anaemia were transfused 1-13 times (mean 2,4) between 1982 and 1987. In Kenya routine screening of blood banks for HIV infection began in 1987. The HIV status of these children was compared with 231 non-transfused children: 106 with Sickle cell anaemia and 125 children with haemoglobin AA. In both transfused and non-transfused children age ranges were similar and were 1-12 years. All children were tested with Wellcozyme Elisa test in duplicate. All tests were performed at least 6 months after the last transfusion. Sixty five transfused sicklers were rechecked one year later. RESULTS: All 429 children were HIV negative. CONCLUSIONS: Out findings suggest that HIV seropositivity is low in Kenyan children. Furthermore, even though blood was unscreened in 1982 - 1987 transfusion did not increase the risk of HIV infection in our study children

In addition the research went ahead to establish the avenues available to mobile phone manufacturers and users in order to enhance safe mobile disposal through a survey.  The research revealed that there was the need for the mobile manufacturers to manufacture handsets from recyclable materials. The manufacturers should also avail information on handset disposal at the point of sale and do a follow-up using the available media. The mobile services providers can also play an important role on mobile phone disposal by availing the information on the face of the scratch cards. In addition they can notify the subscribers on the available disposal channels through text messages. The government through the designated agencies such as the Communications Commission of Kenya (CCK) and National Environmental Management Authority (NEMA) needs to be more assertive in mobile phone disposal measures.

A new impetus is emerging with regard to the potential role that agricultural producer associations might play in improving rural economies. For this study, the use of cereal banking to improve accessibility to premium markets was assessed and the factors influencing farmers' decisions to join them were evaluated. The methodology involved a baseline survey of 213 smallholder maize producers in Bungoma district, western Kenya, plus a logit model analysis to predict the probabilities of farmers joining a cereal bank. Membership of other local community-based organizations and the actual harvests achieved strongly influence farmers' decisions to join a cereal bank.

The increasing land scarcity and the worsening trend of poverty in Kenya in recent years have raised concerns about the focus on land-based agriculture as the basis of growth in the rural areas. This paper combines two complementary data sets obtained from two locations in Kenya, drawn against distinctively different land availability patterns, to examine the diverse rural asset base and key sources of livelihood in the rural areas. The analysis reveals that while access to productive land is still an important determinant of livelihoods in the rural areas, even where land holdings are very small, growth in farm productivity alone may not guarantee households sufficient incomes to escape poverty. We find evidence to suggest that growth of non-farm sector is necessary and may be much more important in reducing risks and vulnerability to poverty and should be equally emphasized if households in such regions are to escape poverty. Off-farm earnings accounted for at least 50 percent of total household incomes in the two research locations. The study further revealed existence of significant barriers to entry to remunerative livelihoods both at farm and off-farm level. The study advocates for expansion of educational services, infrastructure and strengthening of rural institutions to spur broad-based development in the rural areas.

Gituma A, Masika M, Muchangi E, Nyagah L, Otieno V, Irimu G, Wasunna A, Ndiritu M, English M
OBJECTIVE: To evaluate final year medical students' access to new medical information.
METHOD: Cross-sectional survey of final year medical students at the University of Nairobi using anonymous, self-administered questionnaires.
RESULTS: Questionnaires were distributed to 85% of a possible 343 students and returned by 44% (152). Half reported having accessed some form of new medical information within the previous 12 months, most commonly from books and the internet. Few students reported regular access; and specific, new journal articles were rarely accessed. Absence of internet facilities, slow internet speed and cost impeded access to literature; and current training seems rarely to encourage students to seek new information.
CONCLUSION: Almost half the students had not accessed any new medical information in their final year in medical school. This means they are ill prepared for a career that may increasingly demand life-long, self-learning.

Wahome RG, Gitau PK. "An account of a recent outbreak of Marek's Disease in Kenya.". 2001. AbstractWebsite

Data was collected from a number of flocks following an outbreak of Marek's disease in Thika, Kiambu and Nairobi, in 1997. Clinically, the disease presented as a rapid emaciation and depression followed by death. Weekly point and cumulative mortalities were calculated in two of the flocks. Postmortem examination revealed, initially, an atrophy of the bursa of Fabricious. Later, there were turmours in a proportion of the birds. The tumours were observed in the heart muscle, the liver, intestines, and bursa of fabricious. Later, there were tumours in a proportion of birds. The tumours were observed in heart muscles, the liver, intestines, bursa of Fabricious and the skin. There was swelling, oedema and frequently ulceration of the proventriculus. The spleen was usually spotted and enlarged. Microscopically, lesions consisted of a mixture of both proliferative and necrotic lesions the suspected contributory causative factors were high field infections pressure, failure to vaccinate, vaccination failure and lack of quarantine and other disease control measures. Failure to institute effective control measures against the disease is likely to seriously affect the poultry industry in the country.

McNamara J, Worthley LI. "Acid-base balance: part {II}. {Pathophysiology}." Critical Care and Resuscitation: Journal of the Australasian Academy of Critical Care Medicine. 2001;3:188-201. Abstract

OBJECTIVE: To review the normal human acid-base physiology and the pathophysiology and management of acid-base disturbances in a two-part presentation. DATA SOURCES: Articles and published peer-review abstracts and a review of studies reported from 1990 to 2000 and identified through a MEDLINE search of the English language literature on acid-base balance. SUMMARY OF REVIEW: Acid-base disorders are usually classified as metabolic (non-respiratory) or respiratory, depending on whether the primary change occurs in the plasma bicarbonate or the carbonic acid (i.e. carbon dioxide) concentrations, respectively. Respiratory or renal compensatory changes usually occur to minimise the effect of the primary disturbance. A metabolic acidosis arises from an abnormal process that generates non-carbonic acid or an abnormal loss of HCO3- and may be identified by an increase or normal anion gap, respectively. The arterial blood gas usually reveals a pH {\textless} 7.36, PCO2 {\textless} 35 mmHg and 'calculated' HCO3- {\textless} 18 mmol/L. In general, a high anion gap acidosis is managed by treating the disorder generating the acid (thereby ceasing the acid production) and enhancing the clearance of the acid anion (e.g. by metabolism or excretion) thereby regenerating the HCO3- reduced by buffering. A metabolic alkalosis arises from an abnormal process generating excess HCO3-. The arterial blood gas usually reveals a pH {\textgreater} 7.44, PCO2 {\textgreater} 45 mmHg and 'calculated' HCO3- {\textgreater} 32 mmol/L. As the kidney has a large capacity to excrete HCO3-, management usually requires treatment of the processes that are generating as well maintaining the alkalosis. Respiratory acidosis and alkalosis are usually caused by a primary disorder of carbon-dioxide excretion, and correction of the pH disorder only occurs with correction of the primary disease process. CONCLUSIONS: In man, acid-base disturbances are usually classified as either metabolic or respiratory. Correction of the underlying disorder is often all that is required to allow the body to metabolise or excrete the acid or alkali and return the buffer pair (HCO3- and PCO2) to normal.

Department of Periodontology/ Community and Preventive Dentistry, School of Dental Sciences, University of Nairobi, P.O. Box 19676 - 00202, Nairobi, Kenya. OBJECTIVE: To determine the influence of oral hygiene habits and practices on the risk of developing oral leukoplakia. DESIGN: Case control study. SETTING: Githongo sublocation in Meru District. SUBJECTS: Eighty five cases and 141 controls identified in a house-to-house screening. RESULTS: The relative risk (RR) of oral leukoplakia increased gradually across the various brushing frequencies from the reference RR of 1.0 in those who brushed three times a day, to 7.6 in the "don't brush" group. The trend of increase was statistically significant (X2 for Trend : p = 0.001). The use of chewing stick as compared to conventional tooth brush had no significant influence on RR of oral leukoplakia. Non-users of toothpastes had a significantly higher risk of oral leukoplakia than users (RR = 1.8; 95% confidence levels (CI) = 1.4-2.5). Among tobacco smokers, the RR increased from 4.6 in those who brushed to 7.3 in those who did not brush. Among non-smokers, the RR of oral leukoplakia in those who did not brush (1.8) compared to those who brushed was also statistically significant (95% CL = 1.6-3.8). CONCLUSION: Failure to brush teeth and none use of toothpastes are significantly associated with the development of oral leukoplakia, while the choice of brushing tools between conventional toothbrush and chewing stick is not. In addition, failure to brush teeth appeared to potentiate the effect of smoking tobacco in the development of oral leukoplakia. Recommendations: Oral health education, instruction and motivation for the improvement of oral hygiene habits and practices; and therefore oral hygiene status, should be among the strategies used in oral leukoplakia preventive and control programmes.

One of the most remarkable features of the developing brain is its ability to undergo structural change in response to experience. Among the cellular elements that show this kind of plasticity are dendrites, which are the components that receive and process synaptic information. Recent observations indicate that calcium signalling in neurons can regulate dendritic growth and remodelling by several mechanisms, and these mechanisms are likely to be key mediators of structural plasticity in the developing brain.

Hypophosphatemia in diabetic ketoacidosis is well recognized, but is believed to be usually of moderate severity. We describe 2 patients in whom acute hemolytic anemia secondary to severe (0.19-0.35 mmol/l) hypophosphatemia has developed 1-2 days following treatment for diabetic ketoacidosis. Our experience indicates that severe hypophosphatemia requiring phosphate supplementation does occur in diabetic patients, and calls for increased awareness for the clinical and laboratory manifestations of this complication of diabetic ketoacidosis.

Department of Infectious Disease Epidemiology, Imperial College School of Medicine, London, UK. Previous attempts to determine the interactions between filariasis transmission intensity, infection and chronic disease have been limited by a lack of a theoretical framework that allows the explicit examination of mechanisms that may link these variables at the community level. Here, we show how deterministic mathematical models, in conjunction with analyses of standardized field data from communities with varying parasite transmission intensities, can provide a particularly powerful framework for investigating this topic. These models were based on adult worm population dynamics, worm initiated chronic disease and two major forms of acquired immunity (larval- versus adult-worm generated) explicitly linked to community transmission intensity as measured by the Annual Transmission Potential (ATP). They were then fitted to data from low, moderate and moderately high transmission communities from East Africa to determine the mechanistic relationships between transmission, infection and observed filarial morbidity. The results indicate a profound effect of transmission intensity on patent infection and chronic disease, and on the generation and impact of immunity on these variables. For infection, the analysis indicates that in areas of higher parasite transmission, community-specific microfilarial rates may increase proportionately with transmission intensity until moderated by the generation of herd immunity. This supports recent suggestions that acquired immunity in filariasis is transmission driven and may be significant only in areas of high transmission. In East Africa, this transmission threshold is likely to be higher than an ATP of at least 100. A new finding from the analysis of the disease data is that per capita worm pathogenicity could increase with transmission intensity such that the prevalences of both hydrocele and lymphoedema, even without immunopathological involvement, may increase disproportionately with transmission intensity. For lymphoedema, this rise may be further accelerated with the onset of immunopathology. An intriguing finding is that there may be at least two types of immunity operating in filariasis: one implicated in anti-infection immunity and generated by past experience of adult worms, the other involved in immune-mediated pathology and based on cumulative experience of infective larvae. If confirmed, these findings have important implications for the new global initiative to achieve control of this disease.

Clinical Practice Guidelines for childhood illnesses including pneumonia in Kenya are contained in the Ministry of Health Basic Paediatric Protocols. In the presence of a cough and/ or difficulty in breathing and increased respiratory rate for age, pneumonia is diagnosed. In addition to these the presence of lower chest wall indrawing denotes severe pneumonia; The presence of cyanosis, inability to drink/ breastfeed, grunting, level of consciousness using the AVPU scale less than A in addition to the aforementioned is classified as very severe pneumonia. Recommended management is intravascular Crystalline penicillin, gentamycin and oxygen for severe pneumonia, intravascular crystalline penicillin for severe pneumonia and oral amoxyl or cotrimaxole for pneumonia. These guidelines have been disseminated through the Emergency Triage And Treatment Plus (ETAT +) coursesheld since 2007.

Department of Infectious Disease Epidemiology, Imperial College School of Medicine, London, UK. Previous attempts to determine the interactions between filariasis transmission intensity, infection and chronic disease have been limited by a lack of a theoretical framework that allows the explicit examination of mechanisms that may link these variables at the community level. Here, we show how deterministic mathematical models, in conjunction with analyses of standardized field data from communities with varying parasite transmission intensities, can provide a particularly powerful framework for investigating this topic. These models were based on adult worm population dynamics, worm initiated chronic disease and two major forms of acquired immunity (larval- versus adult-worm generated) explicitly linked to community transmission intensity as measured by the Annual Transmission Potential (ATP). They were then fitted to data from low, moderate and moderately high transmission communities from East Africa to determine the mechanistic relationships between transmission, infection and observed filarial morbidity. The results indicate a profound effect of transmission intensity on patent infection and chronic disease, and on the generation and impact of immunity on these variables. For infection, the analysis indicates that in areas of higher parasite transmission, community-specific microfilarial rates may increase proportionately with transmission intensity until moderated by the generation of herd immunity. This supports recent suggestions that acquired immunity in filariasis is transmission driven and may be significant only in areas of high transmission. In East Africa, this transmission threshold is likely to be higher than an ATP of at least 100. A new finding from the analysis of the disease data is that per capita worm pathogenicity could increase with transmission intensity such that the prevalences of both hydrocele and lymphoedema, even without immunopathological involvement, may increase disproportionately with transmission intensity. For lymphoedema, this rise may be further accelerated with the onset of immunopathology. An intriguing finding is that there may be at least two types of immunity operating in filariasis: one implicated in anti-infection immunity and generated by past experience of adult worms, the other involved in immune-mediated pathology and based on cumulative experience of infective larvae. If confirmed, these findings have important implications for the new global initiative to achieve control of this disease.

Objective In global health considerable attention is focused on the search for innovations; however, reports tracking their adoption in routine hospital settings from low-income countries are absent. Design and setting We used data collected on a consistent panel of indicators during four separate cross sectional, hospital surveys in Kenya to track changes over a period of 11 years (2002–2012). Main outcome measures Basic resource availability,use of diagnostics and uptake of recommended practices. Results There appeared little change in availability of a panel of 28 basic resources (median 71% in 2002 to 82% in 2012) although availability of specific feeds for severe malnutrition and vitamin K improved. Use of blood glucose and HIV testing increased but remained inappropriately low throughout. Commonly (malaria) and uncommonly (lumbar puncture) performed diagnostic tests frequently failed to inform practice while pulse oximetry, a simple and cheap technology, was rarely available even in 2012. However, increasing adherence to prescribing guidance occurred during a period from 2006 to 2012 in which efforts were made to disseminate guidelines. Conclusions Findings suggest changes in clinical practices possibly linked to dissemination of guidelines at reasonable scale. However, full availability of basic resources was not attained and major gaps likely exist between the potential and actual impacts of simple diagnostics and technologies representing problems with availability, adoption and successful utilisation. These findings are relevant to debates on scaling up in low income settings and to those developing novel therapeutic or diagnostic interventions.

A study was done to evaluate the removal of a cationic dye from simulated waste water onto rice husks (RH). Spectroscopic methods such as FTIR and SEM/EDX were used for adsorbent characterization. Experimental dependency on solution pH, initial dye concentration, agitation speed, adsorbentparticle size, temperature of the solution and contact time was evaluated. The adsorption data was tested using both Langmuir and Freundlich isotherms. The data fitted well into Langmuir isotherm model with a monolayer adsorption capacity of 6.5 mg/g. Further, the separation factor (RL) value was less than unity indicating a favorable adsorption process. Adsorption kinetics was determined using pseudo-first-order, pseudo-second-order and intra-particle diffusion models. The results showed that the adsorption of malachite green onto rice husks followed pseudo-second-order model with a determination coefficient of 0.986. This work has revealed that rice husks have a great potential to sequester cationic dyes from aqueous solutions and therefore it can be utilized to clean contaminated effluents.

At what point does language structure become advanced? This is a legitimate question since language necessarily is a very advanced concept of human beings. Moreover, having taken years learning language as a student is an indictment to this advanced concept. However, the mention of an advanced course sends wrong signals to students to mean that a course is complicated. The notion of 'advanced courses' being deemed complicated needs to be disabused by the simple understanding that the finer details that may have been overlooked previously take center stage at the advanced stage. The thrust of this book is to look at the finer details of the English language within certain theoretical bearings.

A total of 120 sets of blood cultures were performed aerobically from 60 children with clinically diagnosed septicaemia at Kenyatta National Hospital, Nairobi. Out of these, 36 (30%) sets from 19 (31.7%) patients yielded bacterial growth while 84 (70%) sets from 41 (68.3%) were negative. Salmonella typhimurium was the most frequently isolated bacteria (63%), followed by SlIlphylococcus aureus (15.8%). Salmonella typhimurium isolates were mostly multi-antibiotic resistant, most of them only sensitive to amlkacln and cefotaxime, while all were resistant to ampicillin and co-trimoxazole, the most frequently used antibiotic in this hospital.

Two major etiological agents, hepatitis B virus and aflatoxin B1, are considered to be involved in the induction of liver cancer in Africa. In order to elucidate any synergistic effect of these two agents we conducted a study in various parts of Kenya with different liver cancer incidence in order to establish the rate of exposure to aflatoxin and the prevalence of hepatitis infections. Of all tested individuals 12.6% were positive for aflatoxin exposure as indicated by the urinary excretion of aflatoxin B1-guanine. Assuming no annual and seasonal variation, a regional variation in the exposure was observed. The highest rate of aflatoxin exposure was found in the Western Highlands and Central Province. The incidence of hepatitis infection nationwide as measured by the presence of the surface antigens was 10.6%, but a wide regional variation was observed. A multiplicative and additive regression analysis to investigate if hepatitis and aflatoxin exposure had a synergetic effect in the induction of liver cancer was negative. However, a moderate degree of correlation between the exposure to aflatoxin and liver cancer was observed when the study was limited to certain ethnic groups. The study gives additional support to the hypothesis that aflatoxin is a human liver carcinogen.

Sub-Saharan African (SSA) region continues to experience perennial hunger, poverty and poor health of its people. Agricultural production has remained low over decades and is declining to extremely low staple maize yields below 0.5 t ha–1 season–1 at the smallholder farm scale, against the potential of 4–5 t ha–1 season–1 given modest levels of inputs and good crop husbandry. Constraints contributing to low productivity are numerous, but the planting of poor-quality seed, declining soil fertility, poor markets and value addition to products significantly contribute to poor productivity. Partnerships for development are weak even though there are numerous technologies to improve and sustain agricultural production arising from extensive research and extension in SSA. But, technology adoption rates have been extremely slow, and in some cases we find no adoption. In this chapter we highlight constraints which are bottlenecks for achievement of a green revolution in Africa. Success efforts are reported, but we moot a focus on efficient utilization of abundant and affordable African natural resources, such as phosphate rocks to replenish depleted phosphorus in soils. We argue that to achieve an African green revolution, partnerships with concerned global communities and national institutions, including universities, NGOs, CBOs and farming communities, need to be strengthened. Specifically, human capacity at all levels should be built through training. Without private sector’s strong participation on acquisition of inputs and marketing proven products, it will be difficult to achieve a green revolution

A study that devised a modified method of reporting antibiotic sensitivity results was undertaken. Enterobacteriaceae and Gram positive cocci were tested for drug sensitivity by a disc diffusion method. Zones of bacterial growth inhibition were measured, dividing the isolates into four groups: the highly sensitive, the moderately sensitive, the slightly sensitive and the resistant ones. The slightly sensitive isolates were taken as indicators of antibiotic resistance acquisition. By that system, when more than 50% of the isolates fell into the slightly and resistant groups, that meant that the antibiotic concerned would be discontinued for some time until the bacteria reverted to being moderately sensitive. The study also provided a method of making antibiotic discs from local blotting papers, and a sample of a form on which antibiotic sensitivity results could be recorded was presented. The method is considered to be easy and very appropriate for developing countries in detecting gradual and abrupt acquisition of antibiotic resistance by bacteria.

The genetic model previously proposed for tsavorite- (and tanzanite-) bearing mineralization hosted in the Neoproterozoic Metamorphic Mozambique Belt (stretching from Kenya through Tanzania to Madagascar) is refined on the basis of new Sm-Nd age determinations and detailed Sr-O-S isotope and fluid-inclusion studies. The deposits are hosted within meta-sedimentary series composed of quartzites, graphitic gneisses, calc-silicate rocks intercalated with meta-evaporites, and marbles. Tsavorite occurs either in nodules (also called “boudins”) oriented parallel to the metamorphic foliation in all of the deposits in the metamorphic belt or in quartz veins and lenses located at the hinges of anticlinal folds (Lelatema fold belt and Ruangwa deposits, Tanzania). Gem tanzanite occurs in pockets and lenses in the Lelatema fold belt of northern Tanzania.

The Sm-Nd isotopic data for tsavorites and tanzanites hosted in quartz veins and lenses from Merelani demonstrate that they formed at 600 Ma, during the retrograde metamorphic episode associated with the East African Orogeny. The tsavorites hosted in nodules do not provide reliable ages: their sedimentary protoliths had heterogeneous compositions and their Sm-Nd system was not completely rehomogenized, even at the local scale, by the fluid-absent metamorphic recrystallization.

The initial 87Sr/86Sr isotopic ratios of calcite from marble and tanzanites from Merelani fit with the strontium isotopic composition of Neoproterozoic marine carbonates. Seawater sediment deposition in the Mozambique Ocean took place around 720 Ma.

The quartz-zoisite O-isotopic thermometer indicates a temperature of formation for zoisite between 385 and 448 °C.

The sulfur isotopic composition of pyrite (between –7.8 and –1.3‰ V-CDT) associated with tsavorite in the Lelatema fold belt deposits suggests the contribution of reduced marine sulfate. The sulfur in pyrite in the marbles was likely derived from bacterial sulfate reduction which produced H2S. Fluid inclusion data from tsavorite and tanzanite samples from the Merelani mine indicate the presence of a dominant H2S-S8±(CH4)±(N2)±(H2O)-bearing fluid. In the deposits in Kenya and Madagascar, the replacement of sulfate by tsavorite in the nodules and the boron isotopic composition of tourmaline associated with tsavorite are strong arguments in favor of the participation of evaporites in garnet formation.

AIMS:

Peak left ventricular (LV) relaxation normally precedes peak filling (E), which supports the hypothesis that LV suction contributes to early-diastolic filling. The significance of similar temporal discordance in late diastole has previously not been studied. We describe the time relationships between mitral annular motion and LV filling in early and late diastole and examine the effect of normal ageing on these time intervals.

METHODS AND RESULTS:

A total of 128 healthy subjects aged 25-88 years were studied. Transmitral and pulmonary venous flow reversals (Ar) were recorded by Doppler echocardiography. Mitral annular diastolic displacement-early (E(m)) and late (A(m))-were recorded by Doppler tissue imaging. With reference to electrocardiographic R and P-waves, the following measurements were made: R to peak E-wave (R-E) and E(m) (R-E(m)); onset P to peak A-wave (P-pA), A(m) (P-pA(m)), and Ar (P-pAr). The differences between [(R-E) and (R-E(m))] for early-diastolic temporal discordance (EDTD) and [(P-A) and (P-A(m))] for late-diastolic temporal discordance (LDTD) were calculated. Isovolumic relaxation time (IVRT) was also measured. Early-diastolic temporal discordance was approximately 26 ms in all age groups. Late-diastolic temporal discordance, however, was inversely related to age (r = -0.35, P < 0.001) and IVRT (r = -0.34, P < 0.001) and therefore decreased in the elderly vs. young (13 +/- 10 vs. 23 +/- 10 ms; P < 0.001). In multivariate analysis, age failed to predict LDTD in the presence of IVRT. A, A(m), and Ar were simultaneous at onset, and peak A(m) coincided with peak Ar in all age groups (r = 0.97, P < 0.001). No significant differences were noted in the RR intervals.

CONCLUSIONS:

Sequential prolongation of IVRT with ageing reduces LDTD, thus converging the peaks of A(m), A, and Ar (atrial mechanical alignment)-a potential novel method to identify subjects at increased dependency on atrial contraction for late-diastolic filling

While most governments, including the government of Kenya, have improved their performance through allowing more information exchange using web support, there is increased spread of information crimes targeting government web applications. Structured Query Language (SQL) injection and Cross Site Scripting attack (XSS) are ranked as the two top most vulnerability attacks by the Open Web Application Security Project (OWASP) top 10, 2013 vulnerability list. Recently there have been massive attacks on a number of websites including the government of Kenya. Agent orientation is emerging as a dominant research area and as a new paradigm in provision of solutions to problems. Agents provide developers and designers with a way of structuring applications around autonomous and communicative elements. In this paper, we present a solution that uses multi-agents to detect both SQL injection and XSS attacks vulnerabilities on web applications. The system has been developed using Java programming language and Prometheus methodology as an Agent Oriented Software. It will specifically target websites in development environment
for testing the vulnerabilities before being hosted in the production environment. We have also incorporated the testing of already hosted websites for the two vulnerabilities. The proposed system will help web developers and owners of websites to fix the vulnerabilities and enhance the entire security.
