One hundred and sixty seven volunteer medical students were exposed to intradermal skin tests for schistosomiasis. 35(21%) were positive. On further screening using routine stool and urine examinations, only 11(6.6%) were found to have eggs of Schistosoma mansoni. We conclude that although a useful procedure, schistosomal skin test should not be used alone for the diagnosis of schistosoma infections but should be complimented with the routine stool and urine examinations.
Ouma GO. "Estimation of Areal Rainfall from Satellite Data.". 1988. AbstractUoN Digital Archive

For hydrological, agricultural and other raindependent activities, the estimates of the average rainfall over a catchment are very important.' Most of the methods formulated for estimating the areal average rainfall make use use of raingauges has several disadvantages which are, sometimes, not easily controlled. Due to these drawbacks, recent attempts ha~e been made to utilize remote sensing techniques in the estimation of areal rainfall. Areal estimation of rainfall from METEOSAT satellite data is the main objective of this study. 10-day and monthly total cold-cloud durations (CCD) for the months of January and February, 1987 covering the area within Latitudes 34°E to 400E and Longitudes 50S to 90S of S'butQ.ernTanzania, digitized corresponding to the raingauge statiction network,for three different temperature thresholds was used. These records of • -!Meteosat
data were'compiled at University of Reading, U.K. Daily raingauge records from 147 stations located within the study area were used. These records were used in generating 10-day and monthly total rainfall records which were employed in the study as "ground truth" records. The rainfall records were obtained from the Directorate of Meteorology df Tanzania, Dar es Salaam. The study was divided into three sections. The first section deals with the relationship between the point CCDs and the surface recorded rainfall. Si!.ipl

Abstractmagnitudes_of_climate_variability_and_changes_over_the_arid_and_semi-arid_lands_of_kenya_between_1961_and_2013_period.pdfAmerican Journal of Climate Change

The magnitude and trend of temperature and rainfall extremes as indicators of climate variability and change were investigated in the Arid and Semi-Arid Lands (ASALs) of Kenya using in-situ measurements and gridded climate proxy datasets, and analysed using the Gaussian-Kernel analysis and the Mann-Kendall statistics. The results show that the maximum and minimum temperatures have been increasing, with warmer temperatures being experienced mostly at night time. The average change in the mean maximum and minimum seasonal surface air temperature for the region were 0.74˚C and 0.60˚C, respectively between the 1961-1990 and 1991-2013 periods. Decreasing but statistically insignificant trends in the seasonal rainfall were noted in the area, but with mixed patterns in variability. The March-April-May rainfall season indicated the highest decrease in the seasonal rainfall amounts. The southern parts of the region had a decreasing trend in rainfall that was greater
than that of the northern areas. The results of this study are expected to support sustainable pastoralism system prevalent with the local communities in the ASALs.

Background

Maternal mortality remains high in developing countries and data to monitor indicators of progress in maternal care is needed. We examined the status of maternal care before and after health care worker (HCW) training in WHO recommended Focused Antenatal Care.

Methods

An initial cross-sectional survey was conducted in 2002 in Asembo and Gem in western Kenya among a representative sample of women with a recent birth. HCW training was performed in 2003 in Asembo, and a repeat survey was conducted in 2005 in both areas.

Results

Antenatal clinic (ANC) attendance was similar in both areas (86%) in 2005 and not significantly different from 2002 (90%). There was no difference in place of delivery between the areas or over time. However, in 2005, more women in Asembo were delivered by a skilled assistant compared to Gem (30% vs.23%, P = 0.04), and this proportion increased compared to 2002 (17.6% and 16.1%, respectively). Provision of iron (82.4%), folic acid (72.0%), sulfadoxine-pyrimethamine (61.7%), and anthelminths (12.7%) had increased in Asembo compared to 2002 (2002: 53.3%, 52.8%, 20.3%, and 4.6%, respectively), and was significantly higher than in Gem in 2005 (Gem 2005: 69.7%, 47.8%, 19.8%, and 4.1%, respectively) (P < 0.05 for all). Offering of tests for sexually transmitted diseases and providing information related to maternal health was overall low (<20%) and did not differ by area. In 2005, more women rated the quality of the antenatal service in Asembo as very satisfactory compared to Gem (17% vs. 6.5%, P < 0.05).

Conclusions

We observed improvements in some ANC services in the area where HCWs were trained. However, since our evaluation was carried out 2 years after three-day training, we consider any significant, sustained improvement to be remarkable.

Background.

Maternal mortality, the death of a woman while pregnant or within 42 days of termination of pregnancy, remains disturbingly high in sub-Saharan Africa. It is estimated that 270 000 maternal deaths occurred in the region in 2005 [1]. The UN millennium Development goal (MDG) on maternal health aims to reduce the number of women who die in pregnancy and childbirth by three-quarters between 1990 and 2015 [2]. To achieve this goal, it is estimated that an annual decline in maternal mortality of 5.5% is needed; however between 1990 and 2005 the annual decline was only 0.5% in the sub-Saharan region, compared to 4.2% for the middle income countries of Asia [1,3].

Maternal mortality occurs from risks attributable to pregnancy and child birth as well as from poor availability and quality of health services [4]. The most common causes of maternal mortality in sub-Saharan Africa include haemorrhage (34%), sepsis/infections (10%), hypertensive disorders (9%), HIV/AIDS (6%), and other direct causes (5%); other indirect causes contributed approximately 17% [5].

Experiences from different countries have shown that reducing maternal mortality may depend in part on the availability and use of a professional attendant at labour and delivery and a referral mechanism for obstetric care for managing complications, or the use of basic essential obstetric care facilities for all deliveries [6]. In many developing countries however, the majority of births occur at home, frequently without the help of a skilled assistant (midwife, nurse trained as midwife or a doctor) [7].

The effect of antenatal care on maternal mortality is unclear [8-10]. However, there is broad agreement that antenatal care interventions can lead to improved maternal and newborn health, which can also impact on the survival and health of the infant [11]. Additionally, the ANC visit, which many women in sub-Saharan Africa attend, is an opportunity to reach pregnant women with messages and interventions. A global evaluation of antenatal care has resulted in the recommendation to deliver antenatal services in 4 focused visits (Focussed antenatal care; FANC), one within the first trimester and 3 after quickening, and this schedule is now endorsed by WHO [12,13]. Proven effective antenatal interventions include serologic screening for syphilis, provision of malaria prevention, anti-tetanus immunization, and prevention of mother-to-child transmission of HIV [14,15]. To fully benefit from these interventions, it is important that women start visiting the antenatal clinic (ANC) early in pregnancy.

We evaluated maternal care in western Kenya in 2002 and showed that preventive interventions received at the ANC were inadequate in spite of high (90%) ANC attendance [16]. After this evaluation, the Kenyan Ministry of Health in conjunction with the Johns Hopkins Organization for International Education in Training and Reproductive Health (JHPIEGO) trained healthcare workers in FANC and malaria in pregnancy in part of the study area (Asembo). FANC emphasizes goal-oriented and women-centred care by skilled providers, whereby the quality instead of the quantity of visits is important [17]. The FANC training in 2003 emphasized identification of pre-existing health problems, early detection of danger signs arising from pregnancy, health promotion, provision of intermittent preventive treatment for malaria in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP), provision of iron and folate, birth preparedness, blood pressure measurement, growth monitoring, urine albuminuria and preparation for post-partum family planning. The training was short (3 days) and focused on need-to-know information. An interactive training approach with user-friendly materials was used. These materials enabled the providers to cascade the training to their colleagues in the place of work. Supportive supervision to reinforce skills was undertaken following the training in May-June 2003 in a random sample comprising of 25% of the health facilities in which health care workers had been trained (because of resource constraints not all health facilities received supportive supervision). The focus of the supportive supervision was to identify any gaps and to reinforce knowledge on focused antenatal care and malaria in pregnancy.

In April 2005, we conducted a repeat cross-sectional survey among a random sample of women with a recent birth living in the same areas as the previous survey to assess whether there were improvements in antenatal and delivery care and if there were differences between the area where service providers were trained in FANC and the area where training did not occur.

Methods.

The Centers for Disease Control and Prevention and the Kenya Medical Research Institute (CDC/KEMRI) conduct a demographic surveillance system (DSS) in western Kenya, since 2002. The DSS area is located in Asembo (Rarieda Division, Bondo district) and Gem (Yala and Wagai Divisions, Siaya District), of Nyanza province in western Kenya, and covers 217 villages (75 in Asembo and 142 in Gem) spread over approximately 500 km2 along the shores of Lake Victoria. The vast majority of the population are members of the Luo tribe who earn their living through subsistence farming and fishing [18]. Residents of the DSS are visited in their homes every 4 months to record births, deaths, pregnancies, pregnancy outcomes, immigration and out-migration [19]. Health indicators are poor in the area when compared to national figures, with infant mortality rate estimated at 125 per 1000 live births compared to the national figure of 77 per 1000 live births, under-five mortality rate of 227 per 1000 live births compared to 115 nationally, and overall life expectancy at birth at 38 years (36 for men and 39 for women) compared to 48 nationally [19]. The maternal mortality ratio was estimated at 753 per 100,000 live births in 2003 compared to 414 per 100,000 live births nationally [20]. This area traditionally experienced intense perennial malaria transmission with an estimated entomological inoculation rate of ≈ 60-300 infectious bites per person per year [21]. However, the widespread provision of insecticide-treated nets (ITNs) during a bed net efficacy trial reduced transmission in the study area by about 90% and continuous provision of ITNs has maintained malaria transmission at a low level [22,23]. The prevalence of malaria parasitemia and anaemia was 36% and 53% respectively among pregnant women in a community survey in 2003 [24]. In the 2003 Demographic and Health Survey, the seroprevalence of HIV/AIDS in Nyanza Province (15%) was about twice as high as the national average of 7% [25]. The age-adjusted prevalence rates of HIV in men and women 13-34 years old in the DSS area were 11% and 21%, respectively (P. Amornkul, personal communication). A survey among 13 antenatal clinics in Asembo in 2005 revealed that 7 ANCs did not charge for ANC visits, and 9 provided treatments such as iron and folic acid without charge (P. Ouma, personal communication). We do not have this information for ANCs in Gem.

The sample size estimate for this study was based on a comparison of IPTp use in Asembo and Gem, and aimed to detect at least 50 percentage point difference in IPTp use in Asembo compared to Gem after FANC training, with 80% power and 95% confidence interval. Allowing for 15% failure to recruit, a random sample of 830 women was selected using a list of women who had delivered between 30th of September 2004 and 30th of March 2005 in the DSS [26]. Interviews were conducted by experienced interviewers in the local language using a standardized questionnaire. Participants were asked questions on ANC clinic visits, services received at the clinic, where their last delivery occurred, who assisted with the delivery and satisfaction with antenatal and delivery services. Interviewers were instructed not to probe with options. Questions were similar to the 2002 survey, except for the quality assessment of the maternal services, which had not been included in the 2002 survey.

Data management and statistical methods

We first compared the two areas in the survey in 2005, and then compared the results of the survey in 2005 to the survey in 2002. We examined the use of antenatal and delivery care, and the type of ANC services received, and the satisfaction with the services (2005 only).

Differences in proportions were compared using the Chi-square or Fisher's exact tests as appropriate. For the comparisons of medians, we used the Wilcoxon two sample test (non-parametric). Education level was dichotomized as < 8 years or ≥ 8 years, the minimum number of years required to complete primary education in Kenya. We used Principal Components Analysis (PCA) method to generate weights for the following broad household characteristics: occupation of participant and spouse, source and quality of water, source of fuel for cooking, livestock and asset ownership, and dwelling/housing structure. The scores were used to rank the study participants in socio-economic status (SES) quintiles [27]. A medium/low SES was defined as a rank in the bottom three quintiles of the wealth index. The statistical program SAS was used for all analyses (SAS for windows version 8; SAS Institute, Cary, North Carolina, USA).

Ethical approval for this study was obtained from the institutional review boards of the Kenya Medical Research Institute (Nairobi, Kenya) and the Centers for Disease Control and Prevention (Atlanta, Georgia, USA).

Despite policies to discourage them, informal milk markets account for over 80% of milk sales in most sub-Saharan African (SSA) countries. Informal milk market agents include farmer dairy co-operatives, small traders using bicycles and public or private transport and small retail outlets, such as dairy kiosks, and shops. Studies conducted by the International Livestock Research Institute (ILRI) and national collaborators (e.g., in Kenya1) show that convenient delivery and lower prices (reflecting lower handling and processing costs) are the principal benefits for consumers. Current milk handling and safety regulations in most SSA countries are derived from models in industrialised countries. These may not be appropriate for local market conditions where such regulations may unnecessarily inhibit efficient milk marketing. An important step in developing targeted policies more supportive of market participation of the majority is to collect quantitative and qualitative information about milk-borne health risks under different production and marketing situations. This paper gives an over-view of on-going activities in central Kenya aimed at assessing public health risks from informally marketed milk and presents preliminary results of milk quality and handling practices of informal milk market agents and consumers

Climate and Development. 2017:1-10. Abstractinstitutional_challenges_in_scaling_up_climate_change_adaptation_actions_experiences_from_rural_communities_in_senegal_and_kenya.pdfTaylor &amp; Francis

Regional institutions in Africa have the potential to reinforce the adaptive capacity of rural communities in handling climate change impacts. The institutional arrangements provide the rationale for scaling-up adaptation actions by setting the roles of individual players involved in the planning process at local, national and regional levels. The scaling-up then seeks to extend and disseminate the lessons learnt across the levels to support refinement and inclusive implementation of long-term climate change adaptation strategies. This article discusses these considerations through studies of two rural communities faced with the implementation of climate change adaptation strategies in Senegal and Kenya. The cases illustrate different approaches of institutional arrangements and scaling-up of adaptation actions from community to national levels. The lessons from the
communities are typical of most vulnerable rural regions and were hence important for extended dissemination
considering that the impacts of climate change in Africa are felt largely at community levels. A reduction of this
vulnerability requires efficient and realistic adaptation strategies that seek to understand the rural communities while developing considerate policy-based alternatives at all levels of administration

Mini- and microsatellite sequences show high levels of variation and therefore provide excellent tools for both the genotyping and population genetic analysis of parasites. Herein we describe the identification of a panel of 11 polymorphic microsatellites and 49 polymorphic minisatellites of the protozoan haemoparasite Theileria parva. The PCR products were run on high resolution Spreadex gels on which the alleles were identified and sized. The sequences of the mini- and microsatellites were distributed across the four chromosomes with 16 on chromosome 1, 12 on chromosome 2, 14 on chromosome 3 and 18 on chromosome 4. The primers from the 60 sequences were tested against all the Theileria species that co-infect cattle in East and Southern Africa and were found to be specific for T. parva. In order to demonstrate the utility of these markers, we characterised eight tissue culture isolates of T. parva isolated from cattle in widely separated regions of Eastern and Southern Africa (one from Zambia, one from Uganda, two from Zimbabwe, four from Kenya) and one Kenyan tissue culture isolate from Cape buffalo (Syncerus caffer). The numbers of alleles per locus range from three to eight indicating a high level of diversity between these geographically distinct isolates. We also analysed five isolates from cattle on a single farm at Kakuzi in the central highlands of Kenya and identified a range of one to four alleles per locus. Four of the Kakuzi isolates represented distinct multilocus genotypes while two exhibited identical multilocus genotypes. This indicates a high level of diversity in a single population of T. parva. Cluster analysis of multilocus genotypes from the 14 isolates (using a neighbour joining algorithm) revealed that genetic similarity between isolates was not obviously related to their geographical origin.

HIV continues to challenge health systems, especially in low- and middle-income countries in Sub-Saharan Africa. A qualified workforce of transformational leaders is required to strengthen health systems and introduce policy reforms to address the barriers to HIV testing, treatment, and other HIV services. The 1-year Afya Bora Consortium Fellowship in Global Health capitalizes on academic partnerships between African and U.S. universities to provide interprofessional leadership training through classroom, online, and service-oriented learning in 5 countries in Africa. This fellowship program prepares health professionals to design, implement, scale-up, evaluate, and lead health programs that are population-based and focused on prevention and control of HIV and other public health issues of greatest importance to African communities and health service settings. Afya Bora nurse fellows acquire leadership attributes and competencies that are continuously and systematically tested during the entire program. This multinational training platform promotes interprofessional networks and career opportunities for nurses.

"Studies of human immunodeficiency virus type 1 mucosal viral shedding and transmission in Kenya.". 1999. Abstract

If human immunodeficiency virus type 1 (HIV-1) vaccines are to be highly effective, it is essential to understand the virologic factors that contribute to HIV-1 transmission. It is likely that transmission is determined, in part, by the genotype or phenotype (or both) of infectious virus present in the index case, which in turn will influence the quantity of virus that may be exchanged during sexual contact. Transmission may also depend on the fitness of the virus for replication in the exposed individual, which may be influenced by whether a virus encounters a target cell that is susceptible to infection by that specific variant. Of interest, our data suggest that the complexity of the virus that is transmitted may be different in female and male sexual exposures.

In recent years, the Kenyan government has worked to use Information and communication technologies (ICTs) to increase openness and transparency in their operations. These ICTs are seen as a cost-effective and convenient means to promote public participation in government in Kenya. While many of these efforts have had a government centered approach, the users perspective has been largely ignored. This research takes a user centered approach and looks at how user’s perspectives and attitudes affect adoption of e-government services. The iTax online service was selected as a case study for this research. The research framework is based on technology acceptance models focusing on the aspects of perceived usefulness and perceived ease of use by the users. This view is especially important in developing countries that are still grappling with issues of connectivity and basic infrastructure while developing e-governance initiatives. The data was collected using questionnaires (both paper and online), in depth interviews and a usability study focusing on the primary task of registering on the iTax government service. Findings indicate that the main pain point for both the government and the users is the speed of connectivity. While user/citizens generally think that provision of e-government services is a good idea, there is dissatisfaction with the complexity of the said egovernment service. Findings also show that issues of access in developing countries need to be viewed beyond infrastructure but also on service level. Service level access looks at the extent to which the service is usable to the targeted user. Service level access goes hand in hand with training since some users do have access to the infrastructure but lack the know how to effectively utilize the service. This research concludes that to increase the adoption of e-government services governments need to focus their strategies on the needs of users, their attitudes towards to the services and respond to these needs effectively.

Owino AO, Oyugi JO, Nasirwa OO, Bennun LA. "Patterns of variation in waterbird numbers on four Rift Valley lakes in Kenya, 1991–1999.". 2001. Abstract

Waterbird populations were censused each January from 1991 to 1999 at Lakes Naivasha, Elmenteita and Nakuru and from 1992 at Lake Bogoria. These shallow lakes in the Kenyan Rift Valley fluctuate greatly in water level and alkalinity. All but Naivasha are usually saline; Nakuru and Elmenteita at times support fish, while Bogoria is fishless. A standardized logarithmic index of relative abundance (value 1.0 for the mean) was calculated for each major waterbird group at each lake, and for Naivasha, Elmenteita and Nakuru combined (‘combined lakes’). Its variance was used to compare levels of variation within and across lakes. For the combined lakes, there was high variance in large piscivores (whether combined or separated into groups), grebes, rallids and flamingos. There was low variance in Palaearctic waders (combined or separated into groups), ibises and spoonbills and birds of prey. However, the lakes generally showed idiosyncratic patterns of variation across the different groups. Variance in the indices for birds of prey and kingfishers were consistently low (max. 0.036 and 0.042, respectively), but no group had consistently high variance across all sites. The variance for all birds (other than flamingos) combined was low (0.018 – 0.085) and similar across all lakes and for combined lakes (0.018). For the combined lakes, the variance for flamingos was five times higher than for all other birds (p<0.05), though the two variances were almost equal for Bogoria. Flamingos were the most variable at Naivasha (variance 0.281) followed by Elmenteita (0.177), Nakuru (0.101) and Bogoria (0.024, and significantly lower than all the rest, p<0.05). This was opposite in order to the mean numbers of flamingos recorded at each site. Large piscivores were relatively stable at Naivasha (variance 0.005) but much more variable at Elmenteita (0.199) and Nakuru (0.269). Patterns of variation within lakes were correlated for some groups, such as waders at Naivasha and large piscivores at Nakuru. These correlations could be related to local ecological conditions. However, there were few large correlations across sites, and these were mainly direct. There was, therefore, no evidence that a fixed population of waterbirds was distributing itself across sites according to conditions. Each lake thus seems to represent and independent entity, while the waterbirds they host evidently move much more widely afield than this portion of the Rift Valley.

OWINO MISSOKETCHEMMA. "Peace Initiatives in Africa.". In: Strathmore University Press, 2006. Kisipan, M.L.; 1999. Abstract
BACKGROUND: Peptic ulcer disease (PUD) occurs in up to one fourth of patients with chronic renal failure (CRF). Some of the factors implicated in its causation include hypergastrinaemia, secondary hyperparathyroidism, drugs and, recently, Helicobacter pylori infection. Studies on the latter have been few, with none having been carried out in Kenya. OBJECTIVE: To evaluate the upper gastrointestinal tract endoscopic findings and to determine the prevalence of H. pylori in CRF patients with dyspepsia. STUDY DESIGN AND POPULATION: A prospective study of seventy seven consecutive patients with CRF and dyspepsia compared with consecutive age, sex and socio-economically matched seventy seven controls (no CRF) with dyspepsia. SETTING: Kenyatta National Hospital (KNH), the major referral and teaching hospital, Nairobi, Kenya. METHODS: In both the study population and the controls, upper gastrointestinal endoscopy was carried out. H. pylori was tested for using the biopsy urease test and histology. Patients were considered to have H. pylori if they tested positive on both tests. OUTCOME MEASURES: Findings at endoscopy and presence of H. pylori. RESULTS: Inflammatory lesions (gastritis, duodenitis) (42%) and duodenal ulcers (18.4%) were the commonest findings in the two groups combined. The prevalence of H. pylori in the 154 subjects studied was 54.5%. There was no statistically significant difference between the prevalence of H. pylori in CRF patients (53.2%) and the controls (55.8%) (p = 0.746). Patients with endoscopically proven PUD had a very high prevalence of H. pylori (87.3%) regardless of their renal function status. CONCLUSION: Dyspepsia in patients with or without CRF was due to multiple causes and over 50% were attributable to H. pylori. The prevalence of H. pylon in dyspeptic CRF patients was similar to that in dyspeptic patients with normal renal function.

The global quest for a sustainable bio-economy has brought to the fore importance of engaging agricultural systems in the production and in practice change. There have been issues limiting farmers from improving the practice of manure management as smart climate technology. The objective of this paper was to highlight the constraints, type, and valuation of manure types and information sources that smallholder dairy farmers find it useful to change Practices regarding manure management. In this present study, 336 smallholder dairy farmers were surveyed on various constraints the farmers faced and, on the type, and value of different manure types and information on manure management received by the farmers. The study used descriptive statistics for the variables and compared them using frequency tables. The key findings from this study would support information to stakeholders in inducing climate-smart manure management practices as a climate adaptation practice. The study highlights the type of information systems that determine areas for further investigation as drivers of practice change for smallholder dairy farmers. The paper focuses on these constraints and synthesizes them into factors that determine practice change on manure management by smallholder dairy farmers in order to improve manure management.

Key words: Manure management, agricultural information, smallholder dairy farmers, practice change,
information value.

Some of the factors implicated in its causation include hypergastrinaemia, secondary hyperparathyroidism, drugs and, recently, Helicobacter pylori infection. Studies on the latter have been few, with none having been carried out in Kenya. OBJECTIVE: To evaluate the upper gastrointestinal tract endoscopic findings and to determine the prevalence of H. pylori in CRF patients with dyspepsia. STUDY DESIGN AND POPULATION: A prospective study of seventy seven consecutive patients with CRF and dyspepsia compared with consecutive age, sex and socio-economically matched seventy seven controls (no CRF) with dyspepsia. SETTING: Kenyatta National Hospital (KNH), the major referral and teaching hospital, Nairobi, Kenya. METHODS: In both the study population and the controls, upper gastrointestinal endoscopy was carried out. H. pylori was tested for using the biopsy urease test and histology. Patients were considered to have H. pylori if they tested positive on both tests. OUTCOME MEASURES: Findings at endoscopy and presence of H. pylori. RESULTS: Inflammatory lesions (gastritis, duodenitis) (42%) and duodenal ulcers (18.4%) were the commonest findings in the two groups combined. The prevalence of H. pylori in the 154 subjects studied was 54.5%. There was no statistically significant difference between the prevalence of H. pylori in CRF patients (53.2%) and the controls (55.8%) (p = 0.746). Patients with endoscopically proven PUD had a very high prevalence of H. pylori (87.3%) regardless of their renal function status. CONCLUSION: Dyspepsia in patients with or without CRF was due to multiple causes and over 50% were attributable to H. pylori. The prevalence of H. pylon in dyspeptic CRF patients was similar to that in dyspeptic patients with normal renal function.

To determine the socio-demographic profiles and some clinical aspects of patients with rheumatoid arthritis (RA). DESIGN: Prospective, cross-sectional study. SETTING: Ambulatory out- patient clinics of Kenyatta National Hospital (KNH), a public national and referral hospital. SUBJECTS: Out of 180 patients interviewed and examined, 60 met American College of Rheumatology (ACR) diagnostic criteria of RA. RESULTS: Of the 60 patients recruited 52 (87%) were females with male: female ratio of 1: 6.5. The mean age of patients was 41.38(+/- 16.8) years. There were two peaks of age of occurrence, 20-29 and 40-49 years. In 75% of the study patients, one or more of metacarpophalangeal joints of the hand were involved in the disease. Other frequently involved sites were--wrists, elbows, knees, ankles and glenohumeral joints of shoulders in a symmetrical manner. Serum rheumatoid factor was positive in 78.9% while rheumatoid nodules were present in 13.3% of the study patients. A large majority of patients (88%) had active disease with 18% having mild disease, 38% moderate activity and 32% having severe disease. Only 12% of patients had disease in remission. Forty six point seven per cent (46.7%) of the study patients were on at least one Disease Modifying anti Rheumatic Drugs (DMARD) from a selection of methotrexate, sulphasalazine, hydroxychloroquine and leflunamide. The most frequent drug combination was methotrexate plus prednisolone at 30% of the study population; while 66.7% were on oral prednisolone with 25% of the study patients taking only Non-Steroidal anti Inflammatory Drugs (NSAIDS). CONCLUSION: A large majority of ambulatory patients with RA had active disease. Most of them were sub-optimally treated, especially the use of DMARDS. About two thirds were on oral steroids. Sub-optimal therapy in relatively young patients, peak 20-29 and 40-49 years is likely to impact negatively on their disease control and quality of life.

Owino OJ. "FACTORS DETERMINING CUSTOMER COMMITMENT TO SERVICE PROVIDERS IN KENYAN MOBILE TELEPHONE INDUSTRY."; 2011. Abstractfactors_determining_customer_commitment_to_service_providers_in_kenyan_mobile_telephone_industry.pdf

The study was designed to determine factors which contribute to customer commitment in the mobile telephone service industry. The population of interest comprised of subscribers to mobile telephone companies in Nairobi and Mombasa cities. Two hundred respondents were sampled for purposes of data collection. Data was collected through interviewer administered questionnaires. Factor analysis was used to identify variables which determined customer commitment. It was established that calling habits varied across the two cities. The length of time customers stayed in business relationship had significant influence on their trust for service provider. Commitment to relationship was predominantly determined by level of trust customers had in service providers. Other factors which explained commitment include service quality, reliability and marketing activities by the service provider. Switching costs had significant and positive impact on commitment.
Based on results of analysis, it was concluded that customer commitment to relationship vary across industries and geographic market segments. Commitment in Kenya's mobile telephone industry was determined by customer’s psychological and emotional factors as well as firm related factors. It was also concluded that efforts towards building trust have significant contribution to commitment. In addition, high switching costs increased commitment only when customers had developed trust in the service provider. The study recommends that studies should be carried out to assess the relative contribution of various marketing mix elements to customer commitment.
Key words: commitment, trust, relationship

OBJECTIVE: To determine the accuracy and sensitivity of diagnostic peritoneal lavage in the assessment of intra-abdominal injury using the dipstick method. DESIGN: Prospective study, involving the performance of diagnostic peritoneal lavage in the out patient department and surgical wards prior to surgical intervention. SETTING: Kenyatta National Hospital-General Surgical and Orthopaedic wards and outpatient department. The study was conducted over a duration of six months, starting from January 1995 to July 1995. RESULTS: Ninety six patients with penetrating (68) and blunt (28) abdominal trauma underwent diagnostic peritoneal lavage as evaluation of the severity of abdominal trauma. Dipstick (combur 9 strips) was used to evaluate lavage effluent for red blood cells, white blood cells, protein and bilirubin. Forty three patients had positive diagnostic peritoneal lavage (DPL) results, of which 40 (93%) had positive findings at laparatomy and three (7%) had negative findings at laparatomy. The remaining 53 patients had negative DPL results and were managed conservatively. One patient with a negative DPL result became symptomatic and had a positive laparatomy. Conservatively managed patients were discharged after 24 hours observations without any complications. DPL had an accuracy and sensitivity of 93% and specificity of 98%. CONCLUSION: Diagnostic peritoneal lavage is a cheap, safe and reliable method for assessment of abdominal trauma. The method is easy to perform by trained junior doctors in the OPD, or as a bedside procedure. Use of this method reduced negative laparotomy rate from 50% to 6.9% and average duration of stay from 6.5 days to 1.9 days. This method is recommended as a basic tool in the assessment of abdominal trauma patients.

African Journal of Agricultural Research. 2020;16(7):1007-1014. AbstractA cluster analysis of variables essential for climate change adaptation of smallholder dairy farmers of Nandi County, Kenyadoi.org

Smallholder dairy farmers occupy high potential areas of Kenya and are a source of manure, crops and milk. There is need to use other means of characterising smallholder dairy farmers as they mostly practice mixed farming. The objective of this paper is to use cluster analysis method to characterize the smallholder dairy farmers with added farmer and activity data variables. Clusters of 336 farmers in this study were derived using 28 key variables. This paper demonstrates how to conduct farmer assessments for climate change adaptation activities, climate smart technologies implementation using knowledge of key farmer variables and their distribution in the smallholder dairy farmers of Nandi County, Kenya. This paper demonstrates the importance of integrating agricultural information for smallholder dairy farmers to machine models to characterize the groups and observe the natural groupings. This allows for policy managers to know the key characteristics and how to use them in policy implementation especially in designing climate change adaptation programs factoring education and training of farmers as demonstrated in this paper that they are practicing many activities on their farms.

Key words: Cluster analysis, smallholder dairy farmers, farm utilisation, climate change adaptation.

Studies were conducted on two tea fields, one with tea bushes planted in 1957 and another with tea bushes planted n LgTg in Kaaga, Kenya to determine the response of green tea leaf production to acidulated (Tripleiuper phosphate) and unacidulated (Minjingu phosphate rock) phosphorus fertilisers in the 1993194 af,d lg%lg1 Cropping seasons. The soils yere fairly acidic, low in exchangeable Ca and Mg and high in exchangeable ,ciaty and Al. Al saturation was high ( > 480 g kg-') in both soils. In both tgg3tg4 and 1994195 cropping seasons significantly (P 50.001) higher tea yields were obtained in the field with tea bushes planted in 19?9. The yield for 1994195 cropping season was significantly (P S0.m1) higher. than that for the 1993194 cropping season. There were no significant differences between the two P sources and also that of the control. The higher yields observed in the field with tea planted n lg/g was attributed to the high yielding varieties (clones) which had been planted. Higher yields observed in the 1994195 cropping season were due to improved management practices compared to that of the previous year. The lack of significant response of the crop to either of the P sources was attributed to the 'Al complexation' tolerance mechanism whereby the plant is still able to absorb Ca and P.

Sexual dysfunction can impact a person’s ability to form or sustain intimate relationships and co morbidity between sexual dysfunction and anxiety as well as depression has been reported. Yet epidemiological, etiological, and health association to sexual dysfunction has only begun to be explored in Kenya. To determine the prevalence, types of sexual dysfunction and their socio demographic correlate in diabetic patients. Descriptive cross- sectional study The study was conducted at the outpatient diabetic clinic of Kenyatta National Hospital. This is the main referral hospital in Kenya. A total of 350 participants were enrolled in the study. The Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF) questionnaires were used to evaluate sexual dysfunctions in female and male patients respectively. The participants were composed of 164 females aged between 18-74 years and 186 males aged between 19- 100 years. In males, prevalence of sexual dysfunctions were: erectile dysfunction (68.8%); orgasmic dysfunction (48.4%); sexual desire (81.7%); intercourse satisfaction (86.6%) and overall satisfaction (68.4%).The female sexual dysfunction was 36.6% and was categorized as mild (17.1%); moderate (18.3%) and severe (1.2%). Diabetic patients have a high prevalence of sexual dysfunction

The ultrastructure of the chorioallantoic placenta of the lesser bush baby (Galago senegalensis) has been studied. The placenta was shown to be of the diffuse, epitheliochorial and adeciduate type. The trophoblasts of the chorionic villi, other than those lining the chorionic vesicles, were characterized by the presence of many lipid droplets. In the later stage of gestation, the fetal capillaries indented the trophoblastic epithelium reducing the distance between fetal and maternal circulations. In addition chorionic vesicles were observed. The trophoblasts lining the chorionic vesicles have outward bulging apical surfaces. There are clefts between these cells and this region is occupied by microvilli of adjacent cells. Several layers of fusiform cells that did not extend up into the cores of the chorionic vesicle villi formed the outer component of the vesicular wall. Granulated cells were observed within the maternal connective tissue and their possible role is discussed

Description
A new flavone, named hildeflavone (1) along with 7 other known flavonoids were isolated from the aerial parts of Tephrosia hildebrandtii Vatke. Their characterisation was based on NMR and MS data analysis. The anti-inflammatory properties of the crude extract, isolated compounds and combination of the compounds were investigated in lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMCs). Treatment of the LPS-stimulated PBMCs with the isolated flavonoids at a concentration of 100 µM significantly reduced the production of interleukins (IL-1β, IL-2 and IL-6), interferon-gamma (IFN-γ), granulocyte macrophage-colony stimulating factor (GM-CSF) and tumour necrosis factor-alpha (TNF-α). It was also found that the combination of a flavone and flavanones exhibited remarkable synergistic anti-inflammatory effects on the production of the cytokines.

Description
Phytochemical investigation of Tephrosia vogelii seedpods led to the isolation of twelve compounds: vogelisoflavone A (1), vogelisoflavone B (2), isopongaflavone (3), onogenin, luteolin, 4′,7-dihydroxy-3′-methoxyflavanone, trans-p-hydroxycinnamic acid, tephrosin, 2-methoxygliricidol, dehydrorotenone, 6a,12a-dehydro-α-toxicarol and pinoresinol. Compounds 1 and 2 are reported as new natural products. Isopongaflavone (3) was structurally modified using hydrazine to pyrazoisopongaflavone (4). These compounds were characterized based on their NMR and HRESIMS data. Further, four compounds (1–4) were evaluated for their anti-inflammatory effects in lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMCs). Treatment of the LPS-stimulated PBMCs with the compounds at a concentration of 100 μM suppressed the secretion of interleukin IL-1β interferon-gamma (IFN-γ …

Description
Phytochemical analysis of a methanol–dichloromethane (1:1) extract of the aerial parts of Tephrosialinearis led to the isolation of 18 compounds. Seven of these, namely, lineaflavones A–D (1–4), 6-methoxygeraldone (5), 8″-acetylobovatin (6), and 5-hydroxy-7-methoxysaniculamin A (7) are new compounds. The compounds were characterized based on their NMR and HRMSn data. The anti-inflammatory effects of the crude extract and isolated compounds were evaluated by measuring the levels of interleukins (IL-1β, IL-2, and IL-6), granulocyte-macrophage colony-stimulating factor (GM-CSF), and tumor necrosis factor-α (TNF-α) in lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMCs). The crude extract inhibited the release of all cytokines except IL-1β, which slightly increased in comparison to the LPS control. All the tested compounds suppressed the production of IL-2, GM-CSF, and …
