Consequently, various studies regarding the impact of biotic factors on the macrophytes have been advanced but related studies on environmental parameters have lagged behind. In an attempt to address this gap, sampling on floating species and submergents was carried out in eight sampling sites in 2003 to investigate how they were influenced by a set of environmental factors. Soil texture (sandy sediments; P < 0.05, regression coefficient = - 0.749) and wind were the most important environmental parameters influencing the distribution and abundance of floating macrophytes. Combination of soil texture and lake-bed slope explained the most (86.3%) variation encountered in the submergents. Continuous translocation of the floating dominant water hyacinth to the western parts by wind has led to displacement of the submergents from those areas. In view of these findings, the maintenance and preservation of the steep Crescent Lake basin whose substratum is dominated by sand thus hosting most submergents remain important, if the whole functional purpose of the macrophytes is to be sustained.

Catechol O-methyltransferase (COMT) inactivates neurotransmitters, hormones and drugs such as levodopa. COMT activity is inherited in an autosomal recessive manner and individuals with low activity have thermolabile COMT protein. A low activity allele has been demonstrated at codon 108/158 of the soluble and membrane bound COMT protein, respectively, whereby a G to A transition results in a valine to methionine substitution, rendering the protein more thermolabile. As ethnic differences in erythrocyte COMT activity have been previously demonstrated, the frequency of low activity alleles were investigated in 265 British Caucasian, 99 British South-west Asian and 102 Kenyan individuals. Genotyping of COMT codon 108/158 was performed using a minisequencing method. Erythrocyte COMT activity was measured in 60 British Caucasian individuals by radiochemical assay. The frequency of low activity alleles was 0.54 in Caucasians, 0.49 in South-west Asians, and 0.32 in Kenyans. There was a much lower frequency of individuals with homozygous low activity allele in the Kenyan population (9%) than in Caucasians (31%) or South-west Asians (27%). Erythrocyte COMT activity was lower and less thermostable in individuals with homozygous low activity alleles. The data provide molecular evidence that low COMT is less common in African individuals than the Caucasian population. PMID: 9682265 [PubMed - indexed for MEDLINE]

Forty-five days after emergence, 10 plants each from guard rows and inner rows were  randomly selected and serologically assayed for Potato Virus Y (PVY) and Potato Leaf Roll Virus (PLRV) using DAS ELISA test. Results showd that three aphid species Aphis gossypii (Glover), Macrosiphum euphorbiae (Thomas) and Myzus persicae (Sulzer) colonized on the variety with A. gossypii being the most dominant while M. persicae was least.  Higher aphid population coincided with the short rains experienced in one of the seasons. Synthetic insecticides (Bifethrin  and dimethoate) were the most effective among the treatments in reducing aphid infestation while the neem extract and mineral oil (DC- Tron) had no significant (P<0.05) difference. However, mineral-oil treated plots recorded the lowest PVY  incidence while bifenthrin-Ireated plots had the lowest PLRV incidence.

Kenya is a country of marked environmental and ethnic diversity. A study of osteogenic sarcoma occurring in Kenya from 1968 to 1978 revealed 251 cases, representing between 89% and 100% of the predicted number. Variations in age, sex and anatomical location were within classical limits. However, the incidence of osteogenic sarcoma amongst the Central Bantu was significantly higher than predicted (P less than 0.0001), whilst the incidence among the Western Bantu was significantly lower (P less than 0.002), despite their similar ethnic origins. Two geographically dissimilar areas likewise exhibited significant differences in incidence. The Eastern province showed a higher incidence (P less than 0.02), whereas the Nyanza Province (P less than 0.001) and the adjacent Western Province (P less than 0.005) showed a lower than predicted incidence. These observations suggest that in Kenya a geomedical variable affects the incidence of osteogenic sarcoma and that genetic variation has no effect on incidence.

O. PROFADUOLFRANCISW. "A model for the establishment of an integrated regional geodetic datum.". In: Survey Review, Vol. 32, No 250,. F.N. kamau, G. N Thothi and I.O Kibwage; Submitted. Abstract
A model for the establishment of an integrated geodetic datum covering a region is treated. The integrated geodetic datum is understood here to comprise the geoid, the reference ellipsoid, and the positional coordinates. A comprehensive unified solution model including the three parameters comprising the datum is considered. The estimation model adopted rigorously incorporates determined prior information in the estimation of the datum parameters. Mathematical models together with the pertinent observation equations are presented, followed by a description of the procedure for the aetual setting up of the datum. The observational scheme is based on a system of modular traverses anchored on a trilateration of GPS baselines.

Aminoglutethimide (AG) 500 mg was administered orally to four normal volunteers and eight patients undergoing treatment for metastatic breast cancer. In each subject the acetylator phenotype was established from the monoacetyldapsone (MADDS)/dapsone (DDS) ratio. Acetylaminoglutethimide (acetylAG) rapidly appeared in the plasma and its disposition paralleled that of AG. A close relationship (P less than 0.01) was observed between the acetyl AG/AG and MADDS/DDS ratio suggesting that AG may undergo polymorphic acetylation like DDS. AG half-life was 19.5 +/- 7.7 h in seven fast acetylators of DDS and 12.6 +/- 2.3 h in five slow acetylators and its apparent metabolic clearance was significantly (P less than 0.01) related to the acetylAG/AG ratio. Over 48 h the fast acetylators excreted 7.7 +/- 4.4% of the administered AG dose in the urine as unchanged AG as compared to 12.4 +/- 2.8% in slow acetylators. A much smaller fraction of the dose was excreted as acetylAG: 3.6 +/- 1.5% by fast and 1.9 +/- 1.0% by slow acetylators respectively. After 7 days treatment with AG at an accepted clinical dose regimen to the eight patients there were significant reductions in the half-lives of AG (P less than 0.01) and acetylAG (P less than 0.01) and a trend (0.1 greater than P greater than 0.05) towards reduction of the acetylAG/AG ratio which became significant (P less than 0.05) if the one patient on a known enzyme inducer was omitted. The mean apparent volume of distribution was not significantly (P greater than 0.1) altered but the mean apparent systemic clearance of AG was increased (P less than 0.05). These changes are attributed to auto-induction of oxidative enzymes involved in AG metabolism.

WARUE MRSKARIUKICATHERINE. "Mr. Nicky Nzioki,Mrs.Catherine Kariuki: An Investigation into the process of Compulsory Acquisition and suggestions on the choice of valuation methodology in making claims for compensation for land for various infrastructure.". In: African Journal of Ecology 46(1):22-29. uon press; Submitted. Abstract
Over the last six years there has been a tremendous development of infrastructure projects in virtually all corners of Kenya. This has taken the form of Road Improvement Project, Water and sewerage improvement project and the Electricity Transmission Improvement Project as envisioned in the Kenya Vision 2030. The purpose of this paper is to investigate the principles of compulsory land acquisition and way leaves in the three sectors in Kenya by looking at the current legislative framework governing the entire process of acquisition. In considering the process, the paper explores the various provisions of the relevant act which governs the particular utility envisaged for improvement project component in the Kenya Vision 2030. A critical evaluation of the procedures adopted is outlined in each case and the general public apprehensions towards such acquisitions. The second part of the paper focuses on suggestions on the choice of valuation methodology in making claims for compensation for land for various infrastructure projects in Kenya. This is borne out of the fact that there appear to be very little standardization in the methods adopted by the various bodies. The paper cites several cases under the Electricity Transmission Improvement Project where a large proportion of way leaves are dealt with at local level, with little consistency. Coupled to this is the public concern that electricity lines have potentially serious health effects that continue to attract research and media interest. The paper concludes with a description of the various cases on how to improve compensation paid to those affected by compulsory acquisition in cases of land and way leaves.

Mentorship programs are offered to support students in program completion, confidence building and transitioning to further education or the work force. However mentoring relationships have been faced by challenges such as inadequate knowledge and negative attitude. This study aimed at evaluating knowledge, attitude and perceived benefits on mentorship among the nursing students in Kenyan universities. The study was conducted in September, 2009.  A descriptive cross sectional survey  used both qualitative and quantitative methods to gather information. The study participants were students from University of Nairobi (U.O.N) and Kenya Methodist University (K.E.M.U). A sample of 188 students was selected from a total population of 403 in both universities. The data were coded, entered and analyzed using statistical package for social sciences (SPSS). Presentation of data was done in form of descriptive statistics, frequency distribution and graphs. Pearsons chi square tests were used to compare the two groups. The tests level of significance was set at 5%. Results showed that there was a significance difference between mentorship programmes in the two institutions ( χ 2= 17.02,  d.f=1 , p < 0.001)           . Fourty four (72%) of the students at K.E.M.U felt that the program had positive impact on students

This study was done to determine the nature of utilization of dental auxiliaries and medical emergencies in private dental surgeries in Kenya. A self administering questionnaire with pre-paid postage was mailed to 138 dentists. 27.5% responded. 81.6% used dental auxiliaries and the main reason was to improve efficiency in managing patients. 93.5% of the auxiliaries were on job trained secondary school graduates. 63.2% of the respondents delegated duties which were mainly non-clinical. 26.3% did not delegate any duties. In a descending order, the reasons for non delegation were: that it would be risky to patients, not allowed by law, they did not find it necessary and that auxiliaries were not held responsible if something went wrong. The main duties delegated to the auxiliaries were cleaning of instruments and sterilization, mixing of restorative materials and preparing amalgam. Delegation was done primarily based on auxiliaries capability to perform the procedure and meet the set standards. 57.9% indicated that they rarely encountered medical emergencies. Syncope was the commonest emergency encountered. 72.7% indicated that auxiliaries could not handle medical emergencies because they were not trained. It is concluded that most dentists did not delegate clinical duties to dental auxiliaries and medical emergencies were rare.

OBJECTIVES: The aim was to study dimensional time-dependence of resin/ionomer formulations from 5 min age to one month and to separate out the intrinsic setting shrinkage and hygroscopic expansion effects, by using non-aqueous and aqueous storage media, respectively. METHODS: Materials studied included: A: resin-, B: metal- and C: polyphosphonate-modified glass-ionomer cements [GICs]; and controls of D: poly-acid modified composite [compomer]; and E: resin-composite. Separate specimen groups (n = 5) were stored in different storage-media: (i) silicone fluid; (ii) de-ionized water. Experiments were repeated at 23 and 37 degrees C. Volumetric changes of specimens (4 mm diameter x 6 mm height) were obtained via accurate mass measurements (to 10(-4) g), using Archimedes principle, with silicone or water also used as the Archimedean fluid. These measurements were made periodically over a 30 day period, post fabrication. RESULTS: In silicone at 23 degrees C, all materials underwent further gradual intrinsic shrinkage (after 5 min from mix). This was highly significant (p < 0.05) for the RM-GIC (A). At 37 degrees C, however the RM-GIC expanded, indicating that its cure is temperature-sensitive. In water, at 23 and 37 degrees C, the shrinkage was either partially offset (materials C, D, E), or replaced by appreciable expansions (materials A and B). Differences between RM-GIC (A) and MM-GIC (B) were significant (p < 0.05). SIGNIFICANCE: The deployment of dual storage media made an important contribution to the separate analysis of the volumetric changes due to the on-going setting chemistry in these systems and the time-dependent effects of an aqueous environment.

A study of malaria on the Kano Plain, Kisumu District, Western Kenya, was carried out between April and August, 1985. The study included a knowledge, attitudes and practices (K.A.P.) survey on malaria illness and the mosquito vector. Overall knowledge about malaria illness was found to be good. However, treatment and prevention practices of malaria were found to be poor. Knowledge of the mosquito and its relationship to malaria was found to be high. Knowledge of methods of prevention of mosquito bites was also found to be high but actual use of the methods was low. Knowledge of traditional methods of prevention of mosquito bites was also found to be high. Actual use was again found to be low.

PIP: This research report studies several biochemical and histochemical aspects of cervical carcinoma and explores their use in follow-up of patients undergoing radiotherapy. Material came from 19 patients with invasive cervical carcinoma admitted to Kenyatta National Hospital. A control group consisted of 20 women matched for age who attended clinics at the hospital but were not suffering from any malignant disease; control tissue for histological examination was obtained from 3 women who had undergone hysterectomy for uterine fibroids. Biochemical assays for alkaline and acid phosphatases in patients with cervical carcinoma show an increase in alkaline phosphatase in carcinomatous tissue (35.7 umoles/hr/mg) as opposed to normal tissue (7.2). Acid phosphatase values were only moderately raised. Assays of the same enzymes in blood showed a less marked difference between patients and controls (ranges of 7.5-20.8 and 3-14, respectively). When examined histochemically, increased alkaline phosphatase activity was observed in connective tissue, epithelium of the glands and blood capillaries of tumor tissue. 1 section containing normal tissue bordering carcinomatous tissue demonstrated normal alkaline phosphatase activity in the normal tissue and increased activity in the tumor tissue. In summary, there is increased enzyme activity around the tumor areas, but values for serum levels show an overlap of normal and abnormal cases and are therefore not predictive. Results demonstrate a clear difference in activities of these enzymes in carcinomatous tissue and normal tissue, which may be of value in follow-up care.

 The  research evaluated clinical training provided by the academic institutions that offer Bachelor of Science in Nursing (BScN) program. The purpose of the study was to describe the adequacy of clinical training and the graduates preparedness for nursing practice. The study was conducted from Sept. 2008 to March 2010. Design was cross sectional using questionnaires and focus group interviews (FGI) methods to collect data. The sample comprised of 232 subjects including pre-service BScN graduates and nursing supervisors at four teaching and referral hospitals in Kenya. Results revealed that clinical training provided by academic institutions was adequate but quality of training varied widely among the training institutions. The conclusion was that clinical training provided by BScN programs in Kenya was of high quality. The study recommends that urgent attention was required by nurse educators to address identified gaps in clinical training especially clinical instruction and supervision.

The toxins of C beta-Yoichi, C-468, CD6F, and C-CB19 reacted with anti-C-ST heavy chain and anti-C-ST light chain in immunodiffusion tests and enzyme-linked immunosorbent assay, whereas D-CB16 toxin reacted with anti-D-1873 heavy chain and anti-D-1873 light chain. However, C-6813 toxin reacted with anti-D-1873 heavy chain and anti-C-ST light chain but not with anti-C-ST heavy chain or anti-D-1873 light chain immunoglobulin G. These results indicate common antigens in the heavy chains of C-6813 and D-1873 toxins and in the light chains of C-6813 and C-ST toxins. Further, they provide evidence for heterogeneity within type C1 toxin subunits.

A model for the establishment of an integrated geodetic datum covering a region is treated. The integrated geodetic datum is understood here to comprise the geoid, the reference ellipsoid, and the positional coordinates. A comprehensive unified solution model including the three parameters comprising the datum is considered. The estimation model adopted rigorously incorporates determined prior information in the estimation of the datum parameters. Mathematical models together with the pertinent observation equations are presented, followed by a description of the procedure for the aetual setting up of the datum. The observational scheme is based on a system of modular traverses anchored on a trilateration of GPS baselines.

BackgroundOsgood-Schlatter disease is a common cause of anterior knee pain inthe adolescent. Treatment is usually conservative with surgery reservedfor those who do not respond to this treatment. There is little publishedwork regarding the experience with the disease in our local set up. This series documents the experience with 35 adolescents treated for the disease.DesignCase seriesSubjectsThirty five adolescents with clinical and radiological diagnoses ofOsgood-Schlatter disease at Nairobi and Kenyatta National Hospitals,between 2001and 2007.MethodPatients were evaluated for demographics, knee involvement, activitiesassociated with pain and treatment outcomeResultsThere were 28 males and 7 females, aged 10 to 16 years (mean 12.8years). Thirteen had bilateral knee involvement. Twenty two were involved in active sports while the rest had constant pain and unable to sit or kneel. A family history of the disease was documented in one case.Thirty adolescents responded well to the conservative treatment. Inthe five adolescents who underwent surgery, the patella tendon wasedematous with thickening of the tendon sheath and neovascularisation.All the operated adolescents returned to active sports with 6 weeks after the surgery.ConclusionOsgood-Schlatter disease is a self-limiting condition in majority ofadolescents. Surgery when indicated has an excellent outcome.

This paper describes the methodology and presents preliminary results of an economic appraisal of a community based health care project in Kenya. Community health workers, trained for 12 weeks and deployed in two locations in Kenya's Western Province, act as first contact providers of basic health care and promoters of selected health, sanitation and nutrition practices. A Cost Benefit Analysis has been undertaken using the Willingness to Pay approach to compare the costs of the project and its benefits. The benefits are in the form of more easily accessible basic health care and are measured as consumer surplus accruing to the community. Gain in consumer surplus is consequent on the fall of average user costs and rise in utilisation of the project established points of first contact with primary health care. The argument for the economic viability of the project is validated by the large Net Present Value and Benefit Cost Ratio obtained for the whole of the project area and for the two locations separately. Although the evaluation technique used faces the problem of valuation of community time, aggregation of health care services at all points of first contact and the partial nature of cost benefit analysis evaluations, the results are strongly in favour of decentralisation of primary health care on similar lines in the rest of the country.

Asiatic acid (AA) is a pentacyclic triterpene found in Centella asiatica. In the present study, the mechanism of anticancer effect of AA on skin cancer was investigated. AA decreased viability and induced apoptosis in human melanoma SK-MEL-2 cells in a time- and dose-dependent manner. AA also markedly increased intracellular reactive oxygen species (ROS) level and enhanced the expression of Bax but not Bcl-2 protein in the cells. In addition, AA-induced activation of caspase-3 activity in a dose-dependent manner. Pretreatment with Trolox, an antioxidant, significantly blocked the induction of Bax and activation of caspase-3 in AA-treated cells. Furthermore, Ac-DEVD-CHO, a specific caspase-3 inhibitor, and Trolox prevented the AA-induced apoptosis. AA did not elevate p53 nuclear protein levels that are present in a mutant form in SK-MEL-2 cells. These results suggest that AA-induced apoptosis may be mediated through generation of ROS, alteration of Bax/Bcl-2 ratio and activation of caspase-3, but p53-independent. These results further suggest that AA may be a good candidate for the therapeutic intervention of human skin cancer.

This paper reports the detailed results of a study of the impact of the Health Workers for Change (HWFC) workshop series on clients' perceptions of health services, relationships within the health centre and relations between the health facility and the district health system. The study was carried out in three stages: baseline, intervention and evaluation over a period of 20 months. Data, both qualitative and quantitative, were collected at three levels: client, facility and system. Results indicate that relations between health workers and clients improved a great deal after the intervention while those between the facility and the system remained to a large extent unchanged. The paper concludes that, with external support and help, especially from the health system level, health workers can work towards improving health services and their job satisfaction, which can lead to better health worker-client relations.

The New Constitution of Kenya, Chapter five states that land in Kenya will be held, used and managed in a manner that is equitable, efficient, productive and sustainable. The construction also sets out a number of principles, which will be implemented through a national land policy that developed and reviewed regularly by the government and through legislation. The National Land Policy for Kenya is Sessional Paper No. 3 of 2009, it presents the issues and policy recommendations that were identified, analyzed and agreed by stakeholders. The sessional paper forms the foundation upon which administrative and legislative framework will be built. This is the framework that will drive the critically required land reforms for Kenya. This paper gives a detailed outline of the training and capacity building and research requirements in land management and administration. Its main emphasis being the setting up of a Land Policy research Centre in the light of the new institutional framework suggested in chapter 5 of the Constitution of Kenya and the Sessional paper No.3 of 2009. A suitable land policy centre will undertake research and training for the National Land Commission, in the light of the suggested functions. The paper concludes by suggesting the training and research programmes fro governments and individuals in Kenya and within the continent on land.

Most economically developing countries, after having implemented the democratization of primary education, are now setting their sights on the goal of achieving full enrolment in countries a gradual approach of increasing enrolment annually into secondary schools is perhaps the only realistic option available. This study attempts to project, given this gradual approach, in how many years full enrolment will be achieved not only in each of the 6 provinces in Kenya but also in Kenya as a whole. The results obtained show two distinct categories of provinces: the educationally advantaged provinces which are likely to achieve full enrolment about twenty years before the group of educationally disadvantaged provinces do so.

OBJECTIVE: To determine the prevalence of Xerophthalmia among Kenyan children aged four to seven years in high risk using Conjuctival Impression Cytology and transfer. DESIGN: A cross sectional community based study. SETTING: Mathare slum in Nairobi and Tiva/Ithiani area of Kitui. SUBJECTS: Children aged four to seven years residing in the above areas were assessed for both clinical and cytological features of vitamin A deficiency. RESULTS: Of the 342 children included in this study, 316 (92.0%) were normal, five (1.5%) had XN, 19 (5.9% had XIA and two (0.6%) had XIB. No signs of corneal Xerophthalmia were seen in this study. Conjuctival impression cytology and transfer (CICT) was used to asses for squamous metaplastic changes associated with Vitamin A deficiency (VAD). Seventy five (23.1%) of the children were normal by CICT while 249 (76.9%) were abnormal. In comparing the two areas of study, only 13.2% of the children in Mathare had normal CICT compared to 50% in Kitui. For each of the age groups studied there was significant difference between the two areas with children from Mathare being more deficient than those from Kitui. CONCLUSION: VAD is a significant health problem in the high risk areas assessed by CICT in this study.

A model for the establishment of a four-dimensional regional geodetic reference datum is presented. Starting from the three-dimensional integrated geodetic network model, formulations for the establishment of a four-dimensional regional datum are developed. Astronomic latitudes, astronomic longitudes, gravity values, gravity potential differences, gravity differences, and GPS-vectors are considered as observables. The estimated parameters defining the datura are point coordinates, deflections of the vertical and geoidai undulations, and velocities and accelerations on the positional coordinates. The network datum is considered observed over several epochs with parameters estimated from previous epochs being introduced into later epochs as stochastic prior information parameters.

Aminoglutethimide (AG) 500 mg was administered orally to four normal volunteers and eight patients undergoing treatment for metastatic breast cancer. In each subject the acetylator phenotype was established from the monoacetyldapsone (MADDS)/dapsone (DDS) ratio. Acetylaminoglutethimide (acetylAG) rapidly appeared in the plasma and its disposition paralleled that of AG. A close relationship (P less than 0.01) was observed between the acetyl AG/AG and MADDS/DDS ratio suggesting that AG may undergo polymorphic acetylation like DDS. AG half-life was 19.5 +/- 7.7 h in seven fast acetylators of DDS and 12.6 +/- 2.3 h in five slow acetylators and its apparent metabolic clearance was significantly (P less than 0.01) related to the acetylAG/AG ratio. Over 48 h the fast acetylators excreted 7.7 +/- 4.4% of the administered AG dose in the urine as unchanged AG as compared to 12.4 +/- 2.8% in slow acetylators. A much smaller fraction of the dose was excreted as acetylAG: 3.6 +/- 1.5% by fast and 1.9 +/- 1.0% by slow acetylators respectively. After 7 days treatment with AG at an accepted clinical dose regimen to the eight patients there were significant reductions in the half-lives of AG (P less than 0.01) and acetylAG (P less than 0.01) and a trend (0.1 greater than P greater than 0.05) towards reduction of the acetylAG/AG ratio which became significant (P less than 0.05) if the one patient on a known enzyme inducer was omitted. The mean apparent volume of distribution was not significantly (P greater than 0.1) altered but the mean apparent systemic clearance of AG was increased (P less than 0.05).

OSAAJI DRMUMIAGEOFREY. "Subversion of Patriarchal Ideology: A Case Study of Magdalene, a Woman Oral Narrative Performer from the Samburu of Kenya.". In: Research In African Literatures, Vol. 40, No. 1 (Spring 2009). Indiana University Press; Submitted. Abstract

This paper is based on narrative performances collected in research by students of the University of Nairobi under the guidance of their lecturers. The fieldwork was conducted in February 2005 among nomadic communities in northern Kenya. The main thrust of the paper is to explore how Magdalene, a woman narrator, subverts the dominant masculine ideology inherent in the structure and orientation of oral narratives. The paper identifies the discrete and subtle ways in which the narrator seeks to undermine the manifest inclination of oral narratives towards male dominance. Considering that oral literature is a crucial tool in shaping the world view of a community (especially children), and bearing in mind that women artists perform many of the oral narratives, the imperceptible but subversive potential of such narration becomes even clearer.

Quality of health education during STD case management in Nairobi was assessed in 142 healthcare facilities, through interviews of 165 providers, observation of 441 STD patients managed by these providers, and 165 visits of simulated patients. For observations, scores were high for education on contact treatment (74-80%) and compliance (83%), but unsatisfactory for counselling (52%) and condom promotion (20-41%). The World Health Organization (WHO) indicator for STD case management Prevention Indicator 7 (PI7) (condom promotion plus contact treatment) was poor (38%). Public clinics strengthened for STD care generally performed best, whereas pharmacies and mission clinics performed worst. Compared with observations, scores were higher during interviews and lower during simulated patient visits, indicating that knowledge was not fully translated into practice. Interventions to improve the presently unsatisfactory service quality would be wide distribution of health education materials, ongoing training and supervision of providers, implementation of STD management checklists, and the introduction of pre-packaged kits for STD management.

This paper reports the detailed results of a study of the impact of the Health Workers for Change (HWFC) workshop series on clients' perceptions of health services, relationships within the health centre and relations between the health facility and the district health system. The study was carried out in three stages: baseline, intervention and evaluation over a period of 20 months. Data, both qualitative and quantitative, were collected at three levels: client, facility and system. Results indicate that relations between health workers and clients improved a great deal after the intervention while those between the facility and the system remained to a large extent unchanged. The paper concludes that, with external support and help, especially from the health system level, health workers can work towards improving health services and their job satisfaction, which can lead to better health worker-client relations.

This study was done to determine the nature of utilization of dental auxiliaries and medical emergencies in private dental surgeries in Kenya. A self administering questionnaire with pre-paid postage was mailed to 138 dentists. 27.5% responded. 81.6% used dental auxiliaries and the main reason was to improve efficiency in managing patients. 93.5% of the auxiliaries were on job trained secondary school graduates. 63.2% of the respondents delegated duties which were mainly non-clinical. 26.3% did not delegate any duties. In a descending order, the reasons for non delegation were: that it would be risky to patients, not allowed by law, they did not find it necessary and that auxiliaries were not held responsible if something went wrong. The main duties delegated to the auxiliaries were cleaning of instruments and sterilization, mixing of restorative materials and preparing amalgam. Delegation was done primarily based on auxiliaries capability to perform the procedure and meet the set standards. 57.9% indicated that they rarely encountered medical emergencies. Syncope was the commonest emergency encountered. 72.7% indicated that auxiliaries could not handle medical emergencies because they were not trained. It is concluded that most dentists did not delegate clinical duties to dental auxiliaries and medical emergencies were rare.

OBJECTIVES: The aim was to study dimensional time-dependence of resin/ionomer formulations from 5 min age to one month and to separate out the intrinsic setting shrinkage and hygroscopic expansion effects, by using non-aqueous and aqueous storage media, respectively. METHODS: Materials studied included: A: resin-, B: metal- and C: polyphosphonate-modified glass-ionomer cements [GICs]; and controls of D: poly-acid modified composite [compomer]; and E: resin-composite. Separate specimen groups (n = 5) were stored in different storage-media: (i) silicone fluid; (ii) de-ionized water. Experiments were repeated at 23 and 37 degrees C. Volumetric changes of specimens (4 mm diameter x 6 mm height) were obtained via accurate mass measurements (to 10(-4) g), using Archimedes principle, with silicone or water also used as the Archimedean fluid. These measurements were made periodically over a 30 day period, post fabrication. RESULTS: In silicone at 23 degrees C, all materials underwent further gradual intrinsic shrinkage (after 5 min from mix). This was highly significant (p < 0.05) for the RM-GIC (A). At 37 degrees C, however the RM-GIC expanded, indicating that its cure is temperature-sensitive. In water, at 23 and 37 degrees C, the shrinkage was either partially offset (materials C, D, E), or replaced by appreciable expansions (materials A and B). Differences between RM-GIC (A) and MM-GIC (B) were significant (p < 0.05). SIGNIFICANCE: The deployment of dual storage media made an important contribution to the separate analysis of the volumetric changes due to the on-going setting chemistry in these systems and the time-dependent effects of an aqueous environment.

Description
Adsorption of crystal violet (CV) dye from aqueous solution using dried bark powder of mangrove species Rhizophora mucronata was studied. Characterization of adsorbent was done using FTIR and SEM. Batch experiment was carried out to examine the viability of using mangrove bark for adsorption of CV dye from aqueous solutions under different process conditions. The result revealed that removal of CV increased with contact time, adsorbent dose, initial dye concentration and decreased with increased particle size and ionic strength. pH 7 was the optimum pH for CV dye removal. The adsorption equilibrium for CV dye by Rhizophora mucronata stem-bark was attained within 60 min with removal efficacy of up to 99.8%. Pseudo-second-order kinetic model was best used to describe sorption kinetics while Freundlich isotherm model was appropriate for describing adsorption isotherm. The results demonstrated …

This paper builds a case for a reconsideration of Kenya’s legislation that relates to cultural and societal heritage resources management by briefly revisiting the circumstances that informed the enactment of the related laws. We present the view that existing legislation has tended to serve corporate, multinational and foreign interests at the expense of local and national interests, and that although these Acts may have somewhat served the country in the past, the legislations have turned the cultural heritage management in Kenya into a lame duck framework of abstractions of policy matters, that are irrelevant and unresponsive to changing local and international circumstances. We highlight contradictions between and within varied Acts, and offer suggestions for remedy that are geared toward the development of a cultural management policy with local ownership and universal compatibility.

Background: Alot of research work has been carried out to determine the effectiveness of using atraumatic restorative treatment (ART) in the management of dental caries, but there are still unresolved issues surrounding the use of the technique particularly in very large carious lesions.
Objective: To determine the current survival rates of multi-surface ARTrestorations placed in the primary dentition and any consequences to the restored tooth after premature loss of the restoration.
Study selection: Using a set of specific key words, a Pubmed/Medline search was carried out to retrieve all publications on ARTrestorations placed in primary teeth in the period January 2000 to December 2011. Only publications whose studies had multi-surface ARTrestorations as an item of study were retrieved and relevant data extracted.
Data synthesis: Twelve studies contained in 12 publications fulfilled the selection criteria and were included in the study. The selected publications were analysed by the author to establish the study follow-up period and the survival rate of the multi-surface ARTrestorations for the different follow-up periods. Further information was adduced on any other effects of restoration on the tooth after premature loss of the restoration.
Results: The search findings indicated that the survival rate for most of the multi-surface restorations were generally very low. Further, there were indications that even after the premature loss of the ARTrestorations, most of the affected teeth survived for the period of the study with a number of them having shown no signs of secondary caries or associated dental abscessees.
Conclusion: While the survival rates of multi-surface ARTrestorations in the studies documenetd in the review were low, the ART restorations appeared to provide some beneficial effects to the retention-longevity of the restored tooth even after their premature loss.

"Application Of Molasses In Improving Water Purification Efficiency Of Diatomaceous Earth-Waste Ceramic Membranes.". In: EAI International Conference on Innovations and Interdisciplinary Solutions for Underserved Areas (INTERSOL 2022) . Nile University Of Nigeria Abuja ; 2022. Abstract

The World Health Organization predicts that 90.0% of the 2.3 million people who die annually due to water-borne diseases come from developing countries. At the same time fluorosis occurrence in the world’s geological fluoride belts has left many people maimed due to drinking highly fluoridated water. This work reports on the use of molasses in making carbon-activated diatomaceous earth waste (DE-waste) ceramic membranes with improved mechanical strength and water purification efficiency. The fabricated diatomaceous membranes were soaked in molasses for 24.0 hours and fired at 600.0 for 3.0 hours. The carbon-activated membranes were used to filter water contaminated with Escherichia coli, Rotavirus, and sodium fluoride. The activated carbon obtained in this work had a bulk density of 450.0 kg/m3 and it reduced the porosity of the DE-waste membranes by 18.0%. The activated carbon improved the modulus of rupture (MOR) of the DE-waste membrane by 47.8% and the average pore size of the active DE-waste membrane was 18.4 nm. The filtration process was found to be dependent on the contaminant’s size, concentration, and the external pressure applied to the water during the filtration process. The filtration efficiency of >99.9 in E. coli was concentration and pressure. Membranes reported efficiency of 97.1% and 98.9% in deflouridation and Rotavirus filtration. Thus, molasses is potential material in fabrication of water membranes

Few interventions exist to address the high burden of stillbirths in apparently healthy pregnant women in low- and middle-income countries (LMICs). To establish whether a trial on the impact of routine Doppler screening in a low-risk obstetric population is warranted, we determined the prevalence of abnormal fetal umbilical artery resistance indices among low-risk pregnant women using a low-cost Doppler device in five LMICs.

"An international survey on nasal nitric oxide measurement practices for the diagnosis of primary ciliary dyskinesia." ERJ Open Res. 2022;8(2). Abstract

Nasal nitric oxide (nNO) measurements are used in the assessment of patients suspected of having primary ciliary dyskinesia (PCD), but recommendations for performing such measurements have not focused on children and do not include all current practices. To guide the development of a European Respiratory Society-supported technical standard for nNO measurement in children, an international online survey was conducted to better understand current measurement practices among providers involved in PCD diagnostics. 78 professionals responded, representing 65 centres across 18 countries, mainly in Europe and North America. Nearly all centres measured nNO in children and more than half performed measurements before 5 years of age. The test was often postponed in children with signs of acute airway infection. In Europe, the electrochemical technique was more frequently used than chemiluminescence. A similar proportion of centres performed measurements during exhalation against a resistance (49 out of 65) or during tidal breathing (50 out of 65); 15 centres used only exhalation against a resistance and 15 used only tidal breathing. The cut-off values used to discriminate PCD were consistent across centres using chemiluminescence analysers; these centres reported results as an output (nL·min). Cut-off values were highly variable across centres using electrochemical devices, and nNO concentrations were typically reported as ppb. This survey is the first to determine real-world use of nNO measurements globally and revealed remarkable variability in methodology, equipment and interpretation. These findings will help standardise methods and training.

The global sediment cycle is a fundamental feature of the Earth system, balancing competing factors such as orogeny, physical–chemical erosion and human action. In this Review, values of the magnitudes of several sources and sinks within the cycle are suggested, although the record remains fragmented with uncertainties. Between 1950 and 2010, humans have transformed the mobilization, transport and sequestration of sediment, to the point where human action now dominates these fluxes at the global scale. Human activities have increased fluvial sediment delivery by 215% while simultaneously decreasing the amount of fluvial sediment that reaches the ocean by 49%, and societal consumption of sediment over the same period has increased by more than 2,500%. Global warming is also substantially affecting the global sediment cycle through temperature impacts (sediment production and transport, sea ice cover, glacial ice ablation and loss of permafrost), precipitation changes, desertification and wind intensities, forest fire extent and intensity, and acceleration of sea-level rise. With progressive improvements in global digital datasets and modelling, we should be able to obtain a comprehensive picture of the impacts of human activities and climate warming.

"Need for harmonized long-term multi-lake monitoring of African Great Lakes.". 2022. AbstractWebsite

To ensure the long-term sustainable use of African Great Lakes (AGL), and to better understand the functioning of these ecosystems, authorities, managers and scientists need regularly collected scientific data and information of key environmental indicators over multi-years to make informed decisions. Monitoring is regularly conducted at some sites across AGL; while at others sites, it is rare or conducted irregularly in response to sporadic funding or short-term projects/studies. Managers and scientists working on the AGL thus often lack critical long-term data to evaluate and gauge ongoing changes. Hence, we propose a multi-lake approach to harmonize data collection modalities for better understanding of regional and global environmental impacts on AGL. Climate variability has had strong impacts on all AGL in the recent past. Although these lakes have specific characteristics, their limnological cycles show many similarities. Because different anthropogenic pressures take place at the different AGL, harmonized multi-lake monitoring will provide comparable data to address the main drivers of concern (climate versus regional anthropogenic impact). To realize harmonized long-term multi-lake monitoring, the approach will need: (1) support of a wide community of researchers and managers; (2) political goodwill towards a common goal for such monitoring; and (3) sufficient capacity (e.g., institutional, financial, human and logistic resources) for its implementation. This paper presents an assessment of the state of monitoring the AGL and possible approaches to realize a long-term, multi-lake harmonized monitoring strategy. Key parameters are proposed. The support of national and regional authorities is necessary as each AGL crosses international boundaries.

"Reconstructing the Environmental Context of Human Origins in Eastern Africa Through Scientific Drilling." Annual Review of Earth and Planetary SciencesAnnual Review of Earth and Planetary Sciences. 2022. AbstractWebsite

Paleoanthropologists have long speculated about the role of environmental change in shaping human evolution in Africa. In recent years, drill cores of late Neogene lacustrine sedimentary rocks have yielded valuable high-resolution records of climatic and ecosystem change. Eastern African Rift sediments (primarily lake beds) provide an extraordinary range of data in close proximity to important fossil hominin and archaeological sites, allowing critical study of hypotheses that connect environmental history and hominin evolution. We review recent drill-core studies spanning the Plio?Pleistocene boundary (an interval of hominin diversification, including the earliest members of our genus Homo and the oldest stone tools), and the Mid?Upper Pleistocene (spanning the origin of Homo sapiens in Africa and our early technological and dispersal history). Proposed drilling of Africa's oldest lakes promises to extend such records back to the late Miocene. ?High-resolution paleoenvironmental records are critical for understanding external drivers of human evolution. ?African lake basin drill cores play a critical role in enhancing hominin paleoenvironmental records given their continuity and proximity to key paleoanthropological sites. ?The oldest African lakes have the potential to reveal a comprehensive paleoenvironmental context for the entire late Neogene history of hominin evolution. Expected final online publication date for the Annual Review of Earth and Planetary Sciences, Volume 50 is May 2022.

bstract
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.

This study reports concentrations of Mn, Fe, Cu and Zn analysed from Kenyan bean grains and leaves using Total Reflection X-ray Fluorescence (TXRF) and Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES) methods. Samples of fresh bean leaves and 7 species of dry grains were collected from small scale farmers in Machakos and Kiambu counties. They were delivered to the laboratory where bean grain samples for TXRF analysis were prepared and leaves for both TXRF and ICP-OES. Standard methods of sample preparation successfully tested and used by other authors were used, Average elemental concentrations of the samples were then compared with established sufficiency values mainly given in ranges. Bean leaves from Muguga had sufficient Mn, Ni and Cu concentrations while 6% of the samples had Zn concentrations higher than the sufficiency range. Fe concentrations were consistently high with 97% of the samples having concentrations that were higher than the sufficiency range. No deficiencies were observed from bean leaves from Kyevaluki. For dry bean grains, deficiencies were observed in which four species were found to be deficient in Mn while Zn deficiency was observed in all the species. Fe concentrations were above the sufficiency ranges for all the species but not to toxic levels and 29% of the samples had Cu concentrations that were within the sufficiency range. The obtained data will be essential information for both farmers and policy makers on the nutritional quality of beans in the sampled areas. However, further studies are recommended including soil analysis and elemental bioavailability for full nutritional assessment.

PN R, GO O, O AE, L A, J K. "Assessment of Guideline Concordant Antibiotic Prescribing for Patients with Community Acquired Pneumonia at The Kenyatta National Hospital Medical Wards." Journal of Kenya Association of Physicians. 2022;5(1):34-42. Abstractassessment_of_guideline_concordant_antibiotic_prescribing.pdf

Background: Pneumonia is a major cause of morbidity
and mortality globally. Despite the proven benefits of
guideline concordant antibiotic prescribing, research
has shown that adherence to clinical guideline
recommendations is dismal.
Objectives: The study aims to determine utilization of
Kenyatta National Hospital antibiotic guideline titled
‘The KNH guide to empiric antimicrobial therapy
2018’ in the management of community acquired
pneumonia in the Kenyatta National Hospital medical
wards and the perceived barriers towards the utilization
of this guideline.
Materials and methods: A check list derived from the
Kenyatta National Hospital (KNH) guide to empiric
antimicrobial therapy 2018 was used to assess guideline
concordance based on seven quality indicators:
empiric antibiotic, dose and route of administration,
switch to oral antibiotics, duration of antibiotics (at
least 5 days), collection of microbiological samples
before initiating antibiotics, review of antibiotics at 48
hours and once the culture results are out. Online selfadministered questionnaires were used to determine
attitude and perceived barriers towards utilization
of the KNH guideline among the Internal Medicine
registrars and medical officers.
Analysis: Descriptive statistics were applied in
the representation of each of the seven quality
indicators. These were then compared with the
guideline recommendations and adherence to the
guideline for each parameter was expressed as a
percentage of the total number of patients admitted
with community acquired pneumonia. These were
then graded into the following categories based on the
level of concordance: Good >90%, Intermediate 60-
90%, poor <60%. Questions on the attitude and the
perceived barriers towards KNH guideline utilization
were answered using a 5 point Likert scale. Perceived
barrier statements that were positively formulated
were then recorded so that a lower score meant a
lower level of the perceived barriers and vice versa.
Percentages were then calculated for the total number
of doctors that agreed or strongly agreed that the
barrier was applicable. An open ended question on the
top three barriers to the KNH guideline utilization was
also included in the questionnaire.
Results: For each of the other quality indicators,
adherence to the KNH guideline for patients with
community acquired pneumonia was as follows:
empiric antibiotic choice 48%, collection of samples
for culture prior to antibiotic administration 0%, review
of antibiotics at 48 hours 26.4%, review of antibiotics
with culture results 45.8%, total duration of antibiotics
28.8% and time to switch to oral antibiotics 3.6%. The
top three barriers towards guideline utilization among
the doctors were: unavailability of drugs (52.7%),
inaccessibility of the KNH guideline (45.1%) and lack
of or delay of investigations (34.1%).
Conclusion: This study has demonstrated that the level
of adherence to the seven quality indicators from the
KNH guide is poor with the overall adherence being
35.5%. The recommendation least adhered to was
collection of microbiological samples before initiation
of empiric antibiotics. The most commonly identified
barriers to utilization of the guideline were external
and guideline related barriers.
Key words: Guide to empiric antimicrobial therapy
2018, Guideline Concordance antibiotic prescribing,

The data revolution has increased data demands for leveraging on Big Data in the production of statistics. The paper assesses the adoption of Big Data in research institutes in Kenya. Data were collected from 64 data practitioners based in the 24 research institutes that have a mandate to produce and analyse official statistics. The paper establishes the risks and challenges of using Big Data in statistics, identifies the determinants of adoption of Big Data in statistics and validates the relevance of a Technology Adoption Model (TAM) for predicting the adoption. It is the conclusion that there are immense opportunities for Big Data in statistics if the associated risks and challenges are addressed and the identified key determinants prioritized to promote the adoption.
