Many of the nongenetic causal risk factors of intellectual disability (ID) can be prevented if they are identified early.
There is paucity on information regarding potential risk factors associated with this condition in Kenya.This study aimed to establish
risk factors associated with severity of nongenetic intellectual disability (ID) among children presenting with this condition at
Kenyatta National Hospital (KNH). Methods. A hospital-based cross-sectional study was conducted over the period between March
and June 2017 in pediatric and child/youth mental health departments of Kenyatta National Hospital (KNH), Kenya. It included
children aged 2–18 years diagnosed with ID without underlying known genetic cause. Results. Of 97 patients with nongenetic
ID, 24% had mild ID, 40% moderate, 23% severe-profound, and 10% unspecified ID. The mean age of children was 5.6 (±3.6)
years. Male children were predominant (62%). Three independent factors including “labor complications” [AOR = 9.45, 95% CI =

The global increase in vector borne diseases has been linked to climate change. Seasonal vegetation changes are known to influence disease vector population. However, the relationship is more theoretical than quantitatively defined. There is a growing demand for understanding and prediction of climate sensitive vector borne disease risks especially in regions where meteorological data are lacking. This study aimed at analyzing and quantitatively assessing the seasonal and year-to-year association between climatic factors (rainfall and temperature) and vegetation cover, and its implications for malaria risks in Baringo County, Kenya. Remotely sensed temperature, rainfall, and vegetation data for the period 2004–2015 were used. Poisson regression was used to model the association between malaria cases and climatic and environmental factors for the period 2009–2012, this being the period for which all datasets overlapped. A strong positive relationship was observed between the Normalized Difference Vegetation Index (NDVI) and monthly total precipitation. There was a strong negative relationship between NDVI and minimum temperature. The total monthly rainfall (between 94 -181mm), average monthly minimum temperatures (between 16–21°C) and mean monthly NDVI values lower than 0.35 were significantly associated with malaria incidence rates. Results suggests that a combination of climatic and vegetation greenness thresholds need to be met for malaria incidence to be significantly increased in the county. Planning for malaria control can therefore be enhanced by incorporating these factors in malaria risk mapping.

Knowledge of sex differences in the histomorphology of the carotid body is important in understanding observed differences in respiratory function and disorders. There are few studies on sex differences in the carotid body. This study therefore aimed at describing these differences in the histomorphology features of the human carotid body.
Thirty six random carotid bodies from cardiovascular disease free individuals (20 male, 16 female) obtained during autopsy at the Department of Human Anatomy, University of Nairobi were studied. Specimens obtained within 48 hours of death were fixed in 10% formaldehyde solution and processed routinely for paraffin embedding. Seven micron thick serial sections were stained with H&E, Mason’s trichrome and examined with light microscope. Stereology was done to determine area occupied by parenchyma, stroma and vasculature. Data were analyzed using SPSS version 13.0. The student’s t test was used to compare sex differences. The data are represented using tables and macrographs.
The human carotid body is highly cellular with two varieties of cells namely; chief and sustentacular. It is heavily vascularised and densely innervated. Females showed higher concentration of chief cells, more profuse vascularization and denser innervation when compared with their aged matched male counterparts. The aging changes characterized by fibrosis, cellular degeneration vascular and neural attenuation are less severe in females.
Sex histomorphological differences in the human carotid body characterized by higher population of chief cells, density of vascularity, innervation and blunted age related morphological attenuation underpin differences in its function and disease.
Keywords: gender differences, carotid body, cells, vascularization

Kaoga J, Ouma G, Olago D, Ouma G. "The shrinking grazing fields of the Maasai land under the changing climate system in Kajiado County, Kenya. International Journal of Economics and Sustainable Development.". 2018. Abstract137075-327682-1-pb.pdfWebsite

The Maasai pastoralists have in the last decade experienced disruptions in their economies and livelihoods following climate shifts. For instance, they have been losing up to 30 % of their herd annually to drought related disasters, yet information on the various land uses is still fragmented. This has been worsened by the shortening famine cycles which has impacted pastoral livelihood system as they highly depend on natural resource. Yet, these key resources have been dwindling over the past 30 years compromising their ability to meet basic need such as food. To address this gap, the study focused on long term evaluation of land use. The study’s objective was to determine land use transformations and their impacts particularly on the pastoral livelihood system.

Social media for business is the new frontier for deaf Kenyans, due to the information gap they often experience as they navigate a largely speaking and hearing world. This case studyon the use of social media platforms for business by the deaf in Nairobi includes a special emphasis on the convergence of their natural visual language, sign language with video technology. The research is important to boost socio economic livelihoods of deaf Kenyans for equality in development as well as integrate the Kenyan business industry with the innovation and creativity introduced by the signing „genre‟ of business communication. The results of the study indicate that the dialectical gap between the deaf and hearing is significantly reduced as sign language users can informally interact and exchange ideas, information and updates on business. In addition, the general boost in vocabulary originating from deaf people‟ interest in on-line communication in Kenya is highlighted. It is recommended that the recent immersion of the Kenyan deaf community in the use of smartphones and dissemination of instant messaging needs to be enhanced, as it may yield answers to societal inclusion, while also highlighting deaf cultural pride proponents of the deaf business people‟ creativity.

P Gottesfeld, Were FH, Adogame L, Gharbid S, D. San, Nota MM, Kuepouo G. "Soil Contamination from Lead Battery Manufacturing and Recycling in Seven African Countries." Environmental Research. 2018;161:609-614. Abstract

Lead battery recycling is a growing hazardous industry throughout Africa. We investigated potential
soil con-
tamination inside and outside formal sector recycling plants in seven countries. We collected 118
soil samples at 15 recycling plants and one battery manufacturing site and analyzed them for total
lead. Lead levels in soils ranged from < 40–140,000 mg/kg. Overall mean lead concentrations were
~23,200 mg/kg but, average lead levels were 22-fold greater for soil samples from inside plant
sites than from those collected outside these facilities. Arithmetic mean lead concentrations in
soil samples from communities surrounding these plants were
~2600 mg/kg. As the lead battery industry in Africa continues to expand, it is expected that the
number and size of lead battery recycling plants will grow to meet the forecasted demand. There is
an immediate need to address ongoing exposures in surrounding communities, emissions from this
industry and to regulate site closure financing procedures to ensure that we do not leave behind a
legacy of lead contamination that will impact
millions in communities throughout Africa.

Hadullo K, Oboko R, Omwenga E. "Status of e-learning Quality in Kenya: Case of Jomo Kenyatta University of Agriculture and Technology Postgraduate Students." The International Review of Research in Open and Distributed Learning. 2018;19(1). AbstractFull text Link

There is a substantial increase in the use of learning management systems (LMSs) to support e-learning in higher education institutions, particularly in developing countries. This has been done with some measures of success and failure as well. There is evidence from literature that the provision of e-learning faces several quality issues relating to course design, content support, social support, administrative support, course assessment, learner characteristics, instructor characteristics, and institutional factors. It is clear that developing countries still remain behind in the great revolution of e-learning in Higher Education. Accordingly, further investigation into e-learning use in Kenya is required in order to fill in this gap of research, and extend the body of existing literature by highlighting major quality determinants in the application of e-learning for teaching and learning in developing countries. By using a case study of Jomo Kenyatta University of Agriculture and Technology (JKUAT), the study establishes the status of e-learning system quality in Kenya based on these determinants and then concludes with a discussion and recommendation of the constructs and indicators that are required to support qualify teaching and learning practices

In order to map suitable areas for weather modification in East Africa Community (EAC), investigations were performed to determine spatio-temporal variability and relationship of aerosol, clouds and precipitation during March- April-May (MAM) and October-November-December (OND). Principal Component Analysis (PCA), Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) and Multivariate Regression Analysis (MRA) were used. Identification of near homogeneous zones of Aerosol Optical Depth (AOD), Fine Mode Fraction (FMF), Cloud Top and 3B42 Tropical Rainfall Measuring Mission (TRMM) yielded 13 (14), 20 (18), 11 (10) and 16 (17) significant Principal Components (PCs) for MAM (OND) with explained variance greater than 57%. Aerosols and clouds had positive relationship with precipitation in areas with strong factor loadings. MRA indicated independence of variables used and normality in the model residuals. Backward trajectory analysis indicated differences in origins of transported particles in the atmosphere with strong vertical mixing inlands with mixed aerosols resulting due to mountain blocking systems accounted for enhanced rainfall. Enhanced rainfall was attributed to highly varied AOD and unaffected FMF in the atmosphere. Locations east and west EAC with mean temperatures greater than -10°C were unsuitable for cloud seeding while central EAC region along the great rift-valley and coastal Tanzania exhibited optimal temperatures suitable for cloud seeding. Successful precipitation enhancement will increase available fresh water sources and thus alleviate existing and projected water stress.

Many African countries whose economies are largely based on weather/climate sensitive sectors are vulnerable to long‐term changes in weather and climate. This study is aimed at assessing whether the recent decades have observed any significant trend in the intraseasonal descriptors (ISDs) of wet and dry spells at local and sub‐regional levels at seasonal and monthly timescales over equatorial eastern Africa (EEA). Daily rainfall observations over 36 stations and spanning a period of 51 years (1962–2012) were used.

The study has expanded on previous results that showed contrasting trends on seasonal totals between the two rainfall seasons by demonstrating that this also affects the ISDs. At the local level, it was observed that during the long rainfall season, a given ISD would have a significant trend over several neighbouring locations, which was not the case during the short rainfall season. Secondly, for the short rainfall season, a given location would have significant trend in several ISDs. Finally, when a given ISD had a significant trend at seasonal timescale during the long rainfall season, the same ISD would have significant trends in the second and third months of the season and rarely in the first month. Such a feature was not observed for the short rainfall season. Binomial probability distribution assessment confirmed that the significant trends in the various ISDs during the long rainfall season did not occur by mere chance.

In the Tana River Basin in Kenya, six Regional Circulation Models (RCMs) simulating two Representative Concentration Pathways (RCPs) (i.e., 4.5 and 8.5) were used as input to the Soil and Water Assessment Tool (SWAT) model to determine the possible implications for the hydrology and water resources of the basin. Four hydrological characteristics – water yield, groundwater recharge, base flow and flow regulation – were determined and mapped throughout the basin for three 30-year time periods: 2020–2049, 2040–2069 and 2070–2099. Results were compared with a baseline period, 1983–2011. All four hydrological characteristics show steady increases under both RCPs for the entire basin but with considerable spatial heterogeneity and greater increases under RCP 8.5 than RCP 4.5. The results have important implications for the way water resources in the basin are managed. It is imperative that water managers and policy makers take into account the additional challenges imposed by climate change in operating built infrastructure.

This article examines the consequences that this shift has had for East African firms that are part of global value chains (GVCs). Prior work yielded contradictory expectations: firms might benefit from connectivity through increased efficiencies and improved access to markets, although they might also be further marginalized through increasing control of lead firms. Drawing on extensive qualitative research in Kenya and Rwanda,including 264 interviews, we examine 3 sectors (tea, tourism, and business process outsourcing) exploring overarching, cross-cutting themes. The findings support more pessimistic expectations: small African producers are only thinly digitally integrated in GVCs. Moreover, shifting modes of value chain governance, supported by lead firms and facilitated by digital information platforms and data standards are leading to new challenges for firms looking to digitally integrate. Nevertheless, we also find examples in these sectors of opportunities where small firms are able to cater to emerging niche customers, and local or regional markets. Overall, the study shows that improving connectivity does not inherently benefit African firms in GVCs without support for complementary capacity and competitive advantages.

Background

The decline in global malaria cases is attributed to intensified utilization of primary vector control interventions and artemisinin-based combination therapies (ACTs). These strategies are inadequate in many rural areas, thus adopting locally appropriate integrated malaria control strategies is imperative in these heterogeneous settings. This study aimed at investigating trends and local knowledge on malaria and to develop a framework for malaria control for communities in Baringo, Kenya.

Methods

Clinical malaria cases obtained from four health facilities in the riverine and lowland zones were used to analyse malaria trends for the 2005–2014 period. A mixed method approach integrating eight focus group discussions, 12 key informant interviews, 300 survey questionnaires and two stakeholders’ consultative forums were used to assess local knowledge on malaria risk and develop a framework for malaria reduction.

Results

Malaria cases increased significantly during the 2005–2014 period (tau = 0.352; p < 0.001) in the riverine zone. March, April, May, June and October showed significant increases compared to other months. Misconceptions about the cause and mode of malaria transmission existed. Gender-segregated outdoor occupation such as social drinking, farm activities, herding, and circumcision events increased the risk of mosquito bites. A positive relationship occurred between education level and opinion on exposure to malaria risk after dusk (χ2 = 2.70, p < 0.05). There was over-reliance on bed nets, yet only 68% (204/300) of respondents owned at least one net. Complementary malaria control measures were under-utilized, with 90% of respondents denying having used either sprays, repellents or burnt cow dung or plant leaves over the last one year before the study was conducted. Baraza, radios, and mobile phone messages were identified as effective media for malaria information exchange. Supplementary strategies identified included unblocking canals, clearing Prosopis bushes, and use of community volunteers and school clubs to promote social behaviour change.

Conclusions

The knowledge gap on malaria transmission should be addressed to minimize the impacts and enhance uptake of appropriate malaria management mechanisms. Implementing community-based framework can support significant reductions in malaria prevalence by minimizing both indoor and outdoor malaria transmissions.

This study genetically characterized five populations of the African catfish (Clarius gariepinus) in Kenya. Samples were obtained from five sites in the country–Athi River hatchery, Kisii Fingerling Production Centre (FPC), Jewlett hatchery, Sagana Hatchery Station and Lake Baringo. DNA was extracted from tissue samples, followed by amplification and sequencing of the dloop region. Haplotype diversities, phylogenetic structure and variation at the dloop region of mitochondrial DNA were assessed. Mitochondrial DNA analyses indicated that the sampled species showed genetic diversity between its populations. The genetic results were congruent indicating the differences in diversities and haplotype similarities of catfish samples from different sites. The Sagana, Kisii FPC, Jewlett and Baringo population cluster overlapped indicating possibly shared source of brood stock. The Athi river population was in a different cluster and its distinctiveness is attributed to imported brood stock. Both Athi River hatchery and Lake Baringo populations were highly variable and has great potential for production.

Sediments on the bottom of Lake Challa, a 92-meter deep crater lake on the border of Kenya and Tanzania near Mt. Kilimanjaro, contain a uniquely long and continuous record of past climate and environmental change. The near-equatorial location and exceptional quality of this natural archive provide great opportunities to study tropical climate variability at both short (inter-annual to decadal) and long (glacial-interglacial) time scales; and the influence of this climate variability on the region's freshwater resources, the functioning of terrestrial ecosystems, and the history of the East African landscape in which modern humans (our species, Homo sapiens) evolved and have lived ever since. Supported in part by the International Continental Scientific Drilling Programme (ICDP), the DeepCHALLA project has now recovered the sediment record of Lake Challa down to 214.8 meter below the lake floor, with almost certain 100% cover of the uppermost 121.3 meter (ca.150,000 year BP to present) and estimated 85% cover over the lower part of the sequence, down to the lowermost distinct reflector in the available seismic stratigraphy. This reflector represents a 2 meter thick layer of volcanic sand and silt deposited ca.250,000 years ago, and overlies still older silty lacustrine clays deposited during early lake development. Down-hole logging produced continuous profiles of in-situ sediment composition that confer an absolute depth scale to both the recovered cores and their three-dimensional representation in seismic stratigraphy. As readily observed through the transparent core liners, Lake Challa sediments are finely laminated throughout most of the recovered sequence. Combined with the great time span, the exquisite temporal resolution of these sediments promises to greatly increase our understanding of tropical climate and ecosystem dynamics, and create a long-awaited equatorial counterpart to the high-latitude climate records extracted from the ice sheets of Greenland and Antarctica.

The United Nations and the African Union considers a person aged 65
years and above as a geriatric person. The graying population over the past decades
is showing an exponential growth rate compared to the declining fertility rate. This
population in the developing countries is not boastful of active ageing (successful,
independent ageing) as they are challenged by various health issues and
psychosomatic conditions. They require constant care and in some cases, specialized
care in familiar environments (their homes with relatives) or nursing homes (called
Nyumba za Wazee in Kenya). The researchers with support from literature believe
that technology can offer this specialized care (E-monitoring). This would be offered
in the comfort of their homes through continuous assessment of the geriatric person
relaying information to both the formal and informal caregivers. The objective of this
paper is to explore, summarize and analyse the various technologies in gerontology,
acceptance and adoption models, with the aim of identifying a suitable deployment
model that could be adopted in the context of a developing country.

Researchers have used many instruments to gather data on the use of Information and
Communication Technology to disseminate information on agricultural inputs towards farmers.
These instruments are in English and based on some theories. The Technology Acceptance Model
(TAM), the Diffusion of Innovation Theory (DOI) and the Unified Theory of Acceptance and Use of
Technology (UTAUT) are the three most popular contemporary technology acceptance models. For
other speaking languages especially French and Bambara, there is a need to translate. The increasing
need for non-English data collection instruments and other survey materials has clearly given recent
figures. Despite the availability of tools for translation, the DOI’s instrument has been barely
translated into French and Bambara. In this paper, we used an adaptation method to translate the
DOI’s instrument into French and Bambara. We produced a method for translating English survey
questionnaire into French and Bambara. The method specifies and describes five steps, which are
prepare, translate, pretest, revise and document.

We assessed the association between recent bacterial vaginosis (BV) and incident Mycoplasma genitalium, a sexually transmitted bacterium associated with adverse female reproductive health outcomes. Female sex workers in Mombasa, Kenya completed a monthly sexual behavior interview and clinical examination. During February 2005-February 2006, vaginal fluid specimens collected from women every other month were tested for M. genitalium by nucleic acid amplification testing. Vaginal microbiota was assessed monthly and categorized by Nugent score (0-3 normal, 4-6 intermediate microbiota, 7-10 BV). A discrete time failure analysis for multiple events using logistic regression was used to estimate the odds of incident M. genitalium infection at follow-up visits in women with BV versus normal microbiota at the preceding visit. Among the 280 women, 54.3% were HIV positive. At baseline, 16.1% had prevalent M. genitalium infections and 40.4% had prevalent BV. There were 59 incident M. genitalium infections among 50 women for an incidence rate of 34.6 per 100 person-years. Following adjustment for age, HIV status, and time, prior BV was associated with a 3.5-fold increase in odds of incident M. genitalium (adjusted odds ratio = 3.49; 95% confidence interval: 1.86, 6.56). This strong association suggests that BV may enhance susceptibility to M. genitalium infection.

We report on application of conductive silver paste smeared glass slides as Raman spectroscopy sample substrates for label-free detection of HIV-1 p24 antigen in blood plasma. We also show that the same substrates can be applied in Raman spectroscopic screening of blood plasma for presence of HIV. The characteristic Raman spectrum of HIV-1 p24 antigen displayed prominent bands that were assigned to ribonucleic acids (RNA) and proteins that constitute the antigen. This spectrum can be used as reference during Raman spectroscopic screening for HIV in plasma within the first few days after exposure (<7 days). The Raman spectra obtained from HIV+ plasma displayed unique peaks centered at wavenumbers 928, 990, 1270, 1397, and 1446 cm(-1) attributed to the Raman active vibrations in the virion carbohydrates, lipids, and proteins. Other bands similar to those reported in literature were also seen and assignments made. The attachment of the HIV virions to silver nanoparticles via gp120 glycoprotein knobs was thought to be responsible for the enhanced Raman signals of proteins associated with the virus. The principal component analysis (PCA) applied on the combined spectral data showed that HIV- and HIV+ spectra had differing spectral patterns. This indicated the great power of Raman spectroscopy in HIV detection when plasma samples are deposited onto silver paste smeared glass substrates. The Raman peaks responsible for the segregation of the spectral data in PCA were mainly those assigned to the viral proteins (645, 725, 813, 1270, and 1658 cm(-1)). Excellent results were obtained from Artificial Neural Network (ANN) applied on the HIV+ Raman spectral data around the prominent peak centered at 1270 cm(-1) with R (coefficient of correlation) and R (2) (coefficient of determination) values of 0.9958 and 0.9895, respectively. The method has the potential of being used as quick blood screening for HIV before blood transfusion with the Raman peaks assigned to the virion proteins acting as reference. Graphical Abstract The HIV type 1 virus particle gets attached to the silver nanoparticle contained in the conductive silver paste smear onto a glass slide. This results in strong Raman signals associated with the components of the virion. The signals are collected, dispersed in a spectrometer and displayed on a computer screen. Method can be used as a label-free and rapid HIV screening in blood plasma.
