"Live Attenuated Zoster Vaccine Boosts Varicella Zoster Virus (VZV)-Specific Humoral Responses Systemically and at the Cervicovaginal Mucosa of Kenyan VZV-Seropositive Women." J. Infect. Dis.. 2018;218(8):1210-1218. Abstract

Attenuated varicella zoster virus (VZV) is a promising vector for recombinant vaccines. Because human immunodeficiencyvirus (HIV) vaccines are believed to require mucosal immunogenicity, we characterized mucosal VZV-specific humoral immunity following VZVOka vaccination.

"Prevalence and causes of blindness and vision impairment: magnitude, temporal trends and projections in South and Central Asia." Br J Ophthalmol. 2018. AbstractWebsite

BACKGROUND:To assess prevalence and causes of vision loss in Central and South Asia.

METHODS: A systematic review of medical literature assessed the prevalence of blindness (presenting visual acuity<3/60 in the better eye), moderate and severe vision impairment (MSVI; presenting visual acuity <6/18 but ≥3/60) and mild vision impairment (MVI; presenting visual acuity <6/12 and ≥6/18) in Central and South Asia for 1990, 2010, 2015 and 2020.

RESULTS: In Central and South Asia combined, age-standardised prevalences of blindness, MSVI and MVI in 2015 were for men and women aged 50+years, 3.72% (80% uncertainty interval (UI): 1.39-6.75) and 4.00% (80% UI: 1.41-7.39), 16.33% (80% UI: 8.55-25.47) and 17.65% (80% UI: 9.00-27.62), 11.70% (80% UI: 4.70-20.32) and 12.25% (80% UI:4.86-21.30), respectively, with a significant decrease in the study period for both gender. In South Asia in 2015, 11.76 million individuals (32.65% of the global blindness figure) were blind and 61.19 million individuals (28.3% of the global total) had MSVI. From 1990 to 2015, cataract (accounting for 36.58% of all cases with blindness in 2015) was the most common cause of blindness, followed by undercorrected refractive error (36.43%), glaucoma (5.81%), age-related macular degeneration (2.44%), corneal diseases (2.43%), diabetic retinopathy (0.16%) and trachoma (0.04%). For MSVI in South Asia 2015, most common causes were undercorrected refractive error (accounting for 66.39% of all cases with MSVI), followed by cataract (23.62%), age-related macular degeneration (1.31%) and glaucoma (1.09%).

CONCLUSIONS: One-third of the global blind resided in South Asia in 2015, although the age-standardised prevalence of blindness and MSVI decreased significantly between 1990 and 2015.

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

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

"Effectiveness of peer support to increase uptake of retinal examination for diabetic retinopathy: study protocol for the DURE pragmatic cluster randomized clinical trial in Kirinyaga, Kenya." BMC Public Health. 2018;18(1):871. Abstract

All patients with diabetes are at risk of developing diabetic retinopathy (DR), a progressive and potentially blinding condition. Early treatment of DR prevents visual impairment and blindness. The natural history of DR is that it is asymptomatic until the advanced stages, thus annual retinal examination is recommended for early detection. Previous studies show that the uptake of regular retinal examination among people living with diabetes (PLWD) is low. In the Uptake of Retinal Examination in Diabetes (DURE) study, we will investigate the effectiveness of a complex intervention delivered within diabetes support groups to increase uptake of retinal examination.

"A Prospective Cohort Study of Fertility Desire, Unprotected Sex, and Detectable Viral Load in HIV-Positive Female Sex Workers in Mombasa, Kenya." J. Acquir. Immune Defic. Syndr.. 2018;78(3):276-282. Abstract

Little is known about fertility desire in HIV-positive female sex workers. Fertility desire could increase HIV transmission risk if it was associated with condomless sex or lower adherence to antiretroviral therapy.

"Decay of HIV DNA in the Reservoir and the Impact of Short Treatment Interruption in Kenyan Infants." Open Forum Infect Dis. 2018;5(1):ofx268. Abstract

We compared change in HIV reservoir DNA following continued antiretroviral therapy (ART) vs short treatment interruption (TI) in early ART-treated Kenyan infants. While HIV DNA in the reservoir decayed with continued ART, HIV DNA levels were similar to pre-TI HIV DNA reservoir levels in most children after short TI.

Nomadic lifestyle has been shown to be a significant factor in low immunization coverage. However, other factors which might aggravate vaccination uptake in nomadic pastoralists are poorly understood. Our study aimed at establishing the relative influence of social demographics, missed opportunities, and geographical mobility on severe under vaccination in children aged less than two years living in a nomadic pastoralist community of Kenya.

Davis SM, Pals S, Yang C, Odoyo-June E, Chang J, Walters MS, Jaoko W, Bock N, Westerman L, Toledo C, Bailey RC. "Circumcision status at HIV infection is not associated with plasma viral load in men: analysis of specimens from a randomized controlled trial." BMC Infect. Dis.. 2018;18(1):350. Abstract

Male circumcision provides men with approximately 60% protection from acquiring HIV infection via heterosexual sex, and has become a key component of HIV prevention efforts in sub-Saharan Africa. Possible mechanisms for this protection include removal of the inflammatory anaerobic sub-preputial environment and the high concentration of Langerhans cells on the inside of the foreskin, both believed to promote local vulnerability to HIV infection. In people who do acquire HIV, viral load is partially determined by infecting partner viral load, potentially mediated by size of infecting inoculum. By removing a portal for virion entry, prior male circumcision could decrease infecting inoculum and thus viral load in men who become HIV-infected, conferring the known associated benefits of slower progression to disease and decreased infectiousness.

Do DV, Gichuhi S, Vedula SS, Hawkins BS. "Surgery for postvitrectomy cataract." Cochrane Database Syst Rev. 2018;1:CD006366. AbstractWebsite

BACKGROUND:
Cataract formation or acceleration can occur after intraocular surgery, especially following vitrectomy, a surgical technique for removing the vitreous that is used in the treatment of many disorders that affect the posterior segment of the eye. The underlying problem that led to vitrectomy may limit the benefit from removal of the cataractous lens.

OBJECTIVES:
To evaluate the effectiveness and safety of surgery versus no surgery for postvitrectomy cataract with respect to visual acuity, quality of life, and other outcomes.

SEARCH METHODS:
We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 5), MEDLINE Ovid (1946 to 17 May 2017), Embase.com (1947 to 17 May 2017), PubMed (1946 to 17 May 2017), Latin American and Caribbean Health Sciences Literature database (LILACS) (January 1982 to 17 May 2017), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com); last searched May 2013, ClinicalTrials.gov (www.clinicaltrials.gov); searched 17 May 2017, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en); searched 17 May 2017. We did not use any date or language restrictions in the electronic searches for trials.

SELECTION CRITERIA:
We planned to include randomized controlled trials (RCTs) and quasi-RCTs that had compared surgery versus no surgery to remove the lens from eyes of adults in which cataracts had developed following vitrectomy.

DATA COLLECTION AND ANALYSIS:
Two review authors independently screened the search results according to the standard methodological procedures expected by Cochrane.

MAIN RESULTS:
We found no RCTs or quasi-RCTs that had compared surgery versus no surgery to remove the lens from eyes of adults in which cataracts had developed following vitrectomy.

AUTHORS' CONCLUSIONS:
There is no evidence from RCTs or quasi-RCTs on which to base clinical recommendations for surgery for postvitrectomy cataract. There is a clear need for RCTs to address this evidence gap. Such trials should stratify participants by their age, the retinal disorder leading to vitrectomy, and the status of the underlying disease process in the contralateral eye. Outcomes assessed in such trials may include changes (both gains and losses) of visual acuity, quality of life, and adverse events such as posterior capsular rupture and retinal detachment. Both short-term (six-month) and long-term (one- or two-year) outcomes should be examined.

Cell surface expression of α4β7, α4β1 and αEβ7 integrins play a key role in T cell distribution. Understanding the contribution of integrins to the density and ratios of CD4+: CD4negT cell at the portals of entry for HIV is of fundamental importance for the advance of more effective HIV prevention strategies. We therefore set out to characterize and compare the expression of α4β7, α4β1 and αEβ7 integrins on systemic, cervical and rectal CD4+ and CD4negT cells isolated from a cohort of healthy Kenyan women at low risk for sexually transmitted infections (STI) (n = 45). Here we show that blood and cervix were enriched in α4+β1+CD4+T cells and α4+β7hiCD4+T cells, whereas the rectum had an equal frequency of α4+β7hiCD4+T cells and αE+β7hiCD4+T cells. Most cervical and rectal αE+β7hiCD4+T cells expressed CCR5 as well as CD69. Interestingly, αEβ7 was the predominant integrin expressed by CD4negT cells in both mucosal sites, outnumbering αE+β7hiCD4+T cells approximately 2-fold in the cervix and 7-fold in the rectum. The majority of αE+β7hiCD4negT cells expressed CD69 at the mucosa. Taken together, our results show unique tissue-specific patterns of integrin expression. These results can help in guiding vaccine design and also the use of therapeutically targeting integrin adhesion as a means to preventing HIV.

et.al. JMI. "Adapting Agriculture to Climate Change: Suitability of Banana Crop Production to Future Climate Change Over Uganda.". In: Limits to Climate Change Adaptation. Springer, Cham; 2018. Abstract

The aim of this study was to determine suitability zones of future banana growth under a changing climate to guide the design of future adaptation options in the banana sub-sector of Uganda. The study used high resolution (~1 km) data on combined bioclimatic variables (rainfall and temperature) to map suitability zones of the banana crop while the Providing Regional Climate for Impacts Studies (PRECIS) regional climate model temperature simulations were used to estimate the effect of rising temperature on banana growth assuming other factors constant. The downscaled future climate projections were based on the Intergovernmental Panel on Climate Change (IPCC) Representative Concentration Pathways (RCPs, 2.6, 4.5, 6.0 and 8.5) and Special Report on Emission Scenarios (SRES, A1B and A2) across the period 2011–2090. The methodology involved identification of banana-climate growth thresholds and developing suitability indices for banana production under the high mitigation (RCP 2.6, less adaptation), medium mitigation (RCP 4.5 and RCP 6.0, medium adaptation), no mitigation (RCP 8.5, very high adaptation) scenarios, SRES A1B and A2 scenarios. The FAO ECO-Crop tool was used to determine and map future suitability of banana growth. Banana production indices were determined using a suitability model in the Geographical Information System (GIS) spatial analyst tool. The non-linear banana-temperature regression model was used to assess the impact of future changes in temperature on banana growth. The results revealed unique and distinct banana production suitability and growth patterns for each climate scenario in the sub-periods. RCPs 2.6 and 6.5 are likely to be associated with higher levels of banana production than RCPs 4.5 and 8.5. The results further showed that projected temperature increase under SRES A1B will promote banana growth. In contrast, expected increases in temperatures under SRES A2 are likely to retard banana growth due to high moisture deficits. There is need to develop adaptation option for farming communities to maximize their agricultural production and incomes. The effectiveness of adaptation options needed to combat the impacts will be influenced by the magnitude of the expected climatic changes associated with each scenario, the timing of expected climate change extremes and sensitivity of the crop to climate. This study has provided critical information that will be useful for planning integrated adaptation practices in the banana farming subsector to promote productivity.

Phytochemical investigation of the CH2Cl2/MeOH (1:1) extract of the roots of Lannea rivae (Chiov) Sacleux (Anacardiaceae) led to the isolation of a new alkenyl cyclohexenone derivative: (4R,6S)-4,6-dihydroxy-6-((Z)-nonadec-14′-en-1-yl)cyclohex-2-en-1-one (1), and a new alkenyl cyclohexanol derivative: (2S*,4R*,5S*)-2,4,5-trihydroxy-2-((Z)-nonadec-14′-en-1-yl)cyclohexanone (2) along with four known compounds, namely epicatechin gallate, taraxerol, taraxerone and β-sitosterol; while the stem bark afforded two known compounds, daucosterol and lupeol. Similar investigation of the roots of Lannea schweinfurthii (Engl.) Engl. led to the isolation of four known compounds: 3-((E)-nonadec-16′-enyl)phenol, 1-((E)-heptadec-14′-enyl)cyclohex-4-ene-1,3-diol, catechin, and 1-((E)-pentadec-12′-enyl)cyclohex-4-ene-1,3-diol. The structures of the isolated compounds were determined by NMR spectroscopy and mass spectrometry. The absolute configuration of compound 1 was established by quantum chemical ECD calculations. In an antibacterial activity assay using the microbroth kinetic method, compound 1 showed moderate activity against Escherichia coli while compound 2 exhibited moderate activity against Staphylococcus aureus. Compound 1 also showed moderate activity against E. coli using the disc diffusion method. The roots extract of L. rivae was notably cytotoxic against both the DU-145 prostate cancer cell line and the Vero mammalian cell line (CC50 = 5.24 and 5.20 μg/mL, respectively). Compound 1 was also strongly cytotoxic against the DU-145 cell line (CC50 = 0.55 μg/mL) but showed no observable cytotoxicity (CC50 > 100 μg/mL) against the Vero cell line. The roots extract of L. rivae and L. schweinfurthii, epicatechin gallate as well as compound 1 exhibited inhibition of carageenan-induced inflammation.

Wambui MB, Opere A, Githaiga MJ, Karanja FK. 2017. Assessing the impacts of climate variability and climate change on biodiversity in Lake Nakuru, Kenya. Bonorowo Wetlands 1: 13-24. This study evaluates the impacts of the raised water levels and the flooding of Lake Nakuru and its surrounding areas on biodiversity, specifically, the phytoplankton and lesser flamingo communities, due to climate change and climate variability. The study was to review and analyze noticed climatic records from 2000 to 2014. Several methods were used to ascertain the past and current trends of climatic parameters (temperature, rainfall and evaporation), and also the physicochemical characteristics of Lake Nakuru (conductivity, phytoplankton, lesser flamingos and the lake depth). These included time series analysis, and trend analysis, so the Pearson’s correlation analysis was used to show a relationship between the alterations in lake conductivity to alterations in population estimates of the lesser flamingos and the phytoplankton. Data set extracted from the Coupled Model Intercomparison Project Phase 5 (CMIP5) (IPCC Fifth Assessment Report (AR5) Atlas subset) models were subjected to time series analysis method where the future climate scenarios of near surface temperature, rainfall and evaporation were plotted for the period 2017 to 2100 (projection) for RCP2.6 and RCP8.5 relative to the baseline period 1971 to 2000 in Lake Nakuru were analysed. The results were used to evaluate the impact of climate change on the lesser flamingos and phytoplankton abundance. It was noticed that there was a raise in the mean annual rainfall during the study period (2009 to 2014) which brought the increment in the lake’s surface area from a low area of 31.8 km² in January 2010 to a high of 54.7 km² in Sept 2013, indicating an increment of 22.9 km² (71.92% surface area increment). Mean conductivity of the lake also lessened leading to the loss of phytoplankton on which flamingos feed making them to migrate. A strong positive correlation between conductivity and the lesser flamingo population was noticed signifying that low conductivity affects the growth of phytoplankton and since the lesser flamingos depend on the phytoplankton for their feed, this subsequently revealed that the phytoplankton density could be a notable predictor of the lesser flamingo occurrence in Lake Nakuru. There was also a strong positive correlation noticed between phytoplankton and the lesser flamingo population which confirms that feed availability is a key determining factor of the lesser flamingo distribution in the lake. It is projected that there would be an increment in temperatures, rainfall and evaporation for the period 2017 to 2100 under RCP2.6 and RCP8.5 relative to the baseline period 1971 to 2000 obtained from the Coupled Model Intercomparison Project phase 5 (CMIP5) multi-model ensemble. As a result, it is expected that the lake will further increment in surface area and depth by the year 2100 due to increased rainfall thereby affecting the populations of the lesser flamingos and phytoplankton, as the physicochemical factors of the lake will alter as well during the projected period.

ABSTRACT
The main goal of this research was to examine how bank size moderates the relationship between
bank restructuring and financial performance of commercial banks in Kenya. This study
employed descriptive research design. The study was a census of all the 44 commercial banks in
Kenya which were in operation as at 31st December 2014. This research collected secondary
data gotten from banks annual report for the period of ranging from 2002 to 2014. The regression
analysis model was used to estimate the moderating effect of size on the relationship between
bank restructuring and profitability. The study established that moderation of the relationship
between bank restructuring and financial performance using bank size was not significantly
influenced by financial restructuring, operational restructuring and asset restructuring on
financial performance of commercial banks. However, when bank restructuring variables were
interacted with bank size the findings are that only capital restructuring had a significant
interaction. It was therefore, concluded that bank size therefore moderates the relationship
between bank restructuring and financial performance. The study recommends that there is need
to institute policy reforms geared towards increasing the size of banks either internally by
increasing their asset size or through mergers to expand their size. The regulator can also embark
on setting a minimum size threshold with a view to significantly reducing the number of banks
which would translate into the remaining ones becoming larger. Furthermore, there is need for
commercial banks to strike a balance between enhancing their operations through operational
restructuring or improving profits by focusing on aspects that have a direct positive effect on
profits.

The El Niño event in 2015/2016 was one of the strongest since at least 1950. Through surveys and interviews with key informants, we found businesses in the capital cities of Zambia, Botswana and Kenya experienced major disruption to their activities from El Niño related hydroelectric load shedding, water supply disruption and flooding, respectively. Yet, during the 2015/2016 El Niño, fluctuations in precipitation were not extreme considering the strength of the El Niño event. Results therefore highlight that even fairly moderate precipitation anomalies can contribute to major disruption to economic activity. Addressing the risk of disruption – and supporting the private sector to adapt – is a development priority.

Diarrhoea is a major cause of child mortality. Although oral rehydration solution (ORS) is an efficacious intervention for correcting dehydration, inadequate monitoring may limit its effectiveness in routine settings. We evaluated the effect of using a caregiver-administered chart to monitor oral fluid therapy on hydration status among children with some dehydration.

Potato (Solanum tuberosum L.) synthesizes a variety of bioactive metabolites including phenolic compounds and glycoalkaloids that protects against insects and diseases, and may influence its nutritional quality. Phenolics provide valuable health promoting antioxidants, whereas glycoalkaloid concentrations exceeding the upper safety limit of 20 mg/100 g fresh weight (Fwt) are potential neurotoxins. Therefore, efficient selection for tuber nutritional quality is dependent upon safe and reliable analytical methods. The aim of this study was to determine the changes in the concentration of glycoalkaloids and phenolic compounds during different growth stages in tubers of five selected potato varieties grown in Kenya. α-chaconine and α-solanine were separated and identified by HPLC. Total glycoalkaloids (TGA) and phenolics were determined by UV spectrophotometry. Recovery efficiencies for validation of analytical methods ranged from 85.9-93.5%. Significant differences in TGA and phenolic contents were detected among potato varieties. Tuber TGA content ranged from 6.80 to 10.56 mg/100g Fwt in vars. Dutch Robijn and Tigoni, respectively, and were within the upper safety limit. The corresponding values for chlorogenic acid contents in the examined varieties ranged from 46.39 to 58.04 mg/100 g Fwt. Total phenolic concentration in the examined tuber extracts varied ranged from 129.24 to 192.52 mg CGA/g Fwt. Glycoalkaloid and phenolic production were significantly reduced from time of initiation to maturity at 55 and 125 days, respectively, after planting (DAP). These results demonstrate that tuber phytochemicals were strongly influenced by variety and level of maturity. For nutritional safety and quality purposes, harvesting of mature potato tubers after 125 DAP is recommended

Tropical montane forests are amongst the most threatened ecosystems by climate change. However, little is known about climatic changes already observed in these montane areas in Africa, or the adaptation strategies used by pastoralist communities. This article, focused on three mountains in northern Kenya, aims to fill these knowledge gaps. Focus-group discussions with village elders were organized in 10 villages on each mountain (n = 30). Villages covered different pastoralist ethnic groups. Historical data on rainfall, temperature and fog were gathered from Marsabit Meteorological station. All participants reported changes in the amount and distribution of rainfall, fog, temperature and wind for the past 20–30 years; regardless of the mountain or ethnicity. They particularly highlighted the reduction in fog. Meteorological evidence on rainfall, temperature and fog agreed with local perceptions; particularly important was a 60% reduction in hours of fog per year since 1981. Starting farming and shifting to camel herding were the adaptive strategies most commonly mentioned. Some adaptive strategies were only mentioned in one mountain or by one ethnic group (e.g. starting the cultivation of khat). We highlight the potential use of local communities’ perceptions to complement climatic records in data-deficient areas, such as many tropical mountains, and emphasize the need for more research focused on the adaptation strategies used by pastoralists.

Somalia has faced severe challenges linked to climate variability, which has been exacerbated by conflict and limited governance that persisted for decades. Today climate extremes such as floods, drought, and coastal marine severe systems among others are always associated with the destruction of property and livelihoods; losses of lives lost, migrations, and resource based conflicts among many other miseries. Intergovernmental Panel on Climate Change (IPCC) has shown that climate change is real and requires sound knowledge of local future climate change scenarios. The study attempted to provide projected rainfall and temperature change scenarios over Lower Jubba, Somalia. This was done using the downscaled Coordinated Regional Downscaling Experiment (CORDEX) RCMs data. The simulated temperature and rainfall data derived from the CORDEX RCMs ensemble were compared with the observed data. The study focused on the IPCC projected periods of
2030, 2050 and 2070 benchmarks. Analysis of the projected rainfall indicated a decreasing trend in rainfall leading up to 2030 followed by an increase in rainfall with the 2050 and 2070 scenarios. In the case of temperature, the projections from all the models showed increase in minimum and maximum temperatures in all seasons and sub periods, like being observed by temperature projection over other parts of the world. The 2030, 2050 and 2070 projected rainfall and temperature change scenarios show that Somalia future development and livelihoods will in future face increased threats of climate extremes unless effective climate smart adaptation systems form integral components of national development strategies.

The co-evolution and co-movement of financial time series are of utmost importance in contemporary finance, especially when considering the joint behaviour of asset price realizations. The ability to model interdependencies and volatility spill-over effects introduces interesting dimensions in finance. This paper explores co-integrating relationships between crude oil and distillate fuel prices. Existence of multivariate co-integrating relations and bidirectional Granger-Causality is established among the series. It is also established that even after fitting a full VECM, the residuals are not necessarily multivariate normal suggesting the noise could as well be multivariate GARCH.

A phytochemical investigation of the roots of Aspilia pluriseta led to the isolation of ent-kaurane-type diterpenoids and additional phytochemicals (1–23). The structures of the isolated compounds were elucidated based on Nuclear Magnetic Resonance (NMR) spectroscopic and mass spectrometric analyses. The absolute configurations of seven of the ent-kaurane-type diterpenoids (3–6, 6b, 7 and 8) were determined by single crystal X-ray diffraction studies. Eleven of the compounds were also isolated from the roots and the aerial parts of Aspilia mossambicensis. The literature NMR assignments for compounds 1 and 5 were revised. In a cytotoxicity assay, 12α-methoxy-ent-kaur-9 (11), 16-dien-19-oic acid (1)(IC 50= 27.3±1.9 µM) and 9β-hydroxy-15α-angeloyloxy-ent-kaur-16-en-19-oic acid (3)(IC 50= 24.7±2.8 µM) were the most cytotoxic against the hepatocellular carcinoma (Hep-G2) cell line, while 15α-angeloyloxy-16β, 17-epoxy-ent-kauran-19-oic acid (5)(IC 50= 30.7±1.7 µM) was the most cytotoxic against adenocarcinomic human alveolar basal epithelial (A549) cells.

Chromatographic separation of the extract of the roots of Dorstenia kameruniana (family Moraceae) led to the isolation of three new benzylbenzofuran derivatives, 2-(p-hydroxybenzyl)benzofuran-6-ol (1), 2-(p-hydroxybenzyl)-7-methoxybenzofuran-6-ol (2) and 2-(p-hydroxy)-3-(3-methylbut-2-en-1-yl)benzyl)benzofuran-6-ol(3) (named dorsmerunin A, B and C, respectively), along with the known furanocoumarin, bergapten (4). The twigs of Dorstenia kameruniana also produced compounds 1–4 as well as the known chalcone licoagrochalcone A (5). The structures were elucidated by NMR spectroscopy and mass spectrometry. The isolated compounds displayed cytotoxicity against the sensitive CCRF-CEM and multidrug-resistant CEM/ADR5000 leukemia cells, where compounds 4 and 5 had the highest activities (IC50 values of 7.17 μM and 5.16 μM, respectively) against CCRF-CEM leukemia cells.

Beverage fraud involving counterfeiting of brand spirits is an increasing problem not only due to deception of the consumer but also because it poses health risks e.g. from possible methanol admixture. Suspicious spirit samples from Russia and Kenya were analysed using 1H nuclear magnetic resonance (NMR) spectroscopy in comparison to authentic products. Using linear regression analysis of spectral integral values, 4 counterfeited samples from Russia and 2 from Kenya were easily identifiable with R2 < 0.7. Sensory analysis using triangle test methodology confirmed significant taste differences between counterfeited and authentic samples but the assessors were unable to correctly identify the counterfeited product in the majority of cases. An important conclusion is that consumers cannot assumed to be self-responsible when consuming counterfeit alcohol because there is no general ability to organoleptically detect counterfeit alcohol.

A.T.Aluda, Amugune BK, Abuga KO, Kamau FN. "Development and Validation of a Gas Chromatographic Method for Determination of Menthol in Cold-Cough Syrups." PJK. 2018;23(3):90-93. Abstract

Background
Common cold is the most common infection of the upper respiratory tract and cold-cough syrups are often prescribed. Although menthol is one of the common constituents of these syrups, quality checks on cold-cough syrups normally target the major active pharmaceutical ingredients without regard to menthol content.

Objective
To develop and validate a gas chromatography method for determination of menthol in cold-cough syrups.

Methods
A simple, rapid, robust, accurate and reliable Gas Chromatography method was developed and validated for the determination of menthol in cold-cough syrups that may also contain ambroxol, chlorpheniramine, guaifenesin, bromhexine and salbutamol.

Results
Optimized chromatographic conditions were: A ZB-WAXplus 60m ×0.25mm; 0.25μm fused silica capillary column. Oven temperature program of 110 0C (2 min), ramp 10 0C/min to 190 0C (2 min). Injector port temperature maintained at 240 0C. Injection volume of 1.0 μl split in the ratio of 50:1. Carrier gas as nitrogen at 1.0mL/min which also serves as make up gas (30 mL/min) in the flame ionization detector (260 0C). Other detector gases were hydrogen (30 mL/ min) and industrial air (300 mL/ min) and the diluent for samples and standards was grade chloroform.
From recovery studies, 97.56 to 102.97 % recovery was reported. Repeatability studies had a coefficient of variation of 0.55 while intermediate precision was 0.32. The method was linear over a range of 0.042 to 0.169 mg/mL with a coefficient of determination (R2) 0.9986.
Of the 21 samples analyzed, only 10 samples (47.6 %) complied with assay specifications of 90.0 to 110.0 % label claim for finished products according to the United States Pharmacopeia 2016.

Conclusion and recommendation
A gas chromatographic method was developed and validated for the determination of menthol in cold-cough syrups in Kenya. This method can be used together with a validated high-performance liquid chromatography method to assay cold-cough syrups that may also contain ambroxol, bromhexine, chlorpheniramine maleate, guaifenesin and salbutamol.
This method can be useful in routine analysis such as pre-registration studies as well as post market surveillance to curb substandard and counterfeit cold-cough syrups.

The objective of the study was to determine the influence of ingratiation on employees’ career mobility. The study used a descriptive survey and a population study of 169 employees with a response rate of 122(72.2%). This is considered sufficient as recommended by experts (Mugenda and Mugenda, 2009). Primary data was collected using self-administered structured questionnaires. Descriptive statistics was used to analyse the data and the hypothesis formulated was analysed using linear regression analysis. The results confirmed the hypothesis thatingratiation influences career mobility (R2=.944, F=2011.237, P≤0.05). The correlation coefficient for the model was 0.971 which also confirms that there is a strong relationship between ingratiation and career mobility. The study recommends that objective means of performance appraisals be established and followed by superiors to ensure fair and credible ways of career mobility to its employees. The paper suggests if the same study can be replicated in other organizations using a longitudinal research design.

East African landscapes today are the result of the cumulative effects of climate and land-use change over millennial timescales. In this review, we compile archaeological and palaeoenvironmental data from East Africa to document land-cover change, and environmental, subsistence and land-use transitions, over the past 6000 years. Throughout East Africa there have been a series of relatively rapid and high-magnitude environmental shifts characterised by changing hydrological budgets during the mid- to late Holocene. For example, pronounced environmental shifts that manifested as a marked change in the rainfall amount or seasonality and subsequent hydrological budget throughout East Africa occurred around 4000, 800 and 300 radiocarbon years before present (yr BP). The past 6000 years have also seen numerous shifts in human interactions with East African ecologies. From the mid-Holocene, land use has both diversified and increased exponentially, this has been associated with the arrival of new subsistence systems, crops, migrants and technologies, all giving rise to a sequence of significant phases of land-cover change. The first large-scale human influences began to occur around 4000 yr BP, associated with the introduction of domesticated livestock and the expansion of pastoral communities. The first widespread and intensive forest clearances were associated with the arrival of iron-using early farming communities around 2500 yr BP, particularly in productive and easily-cleared mid-altitudinal areas. Extensive and pervasive land-cover change has been associated with population growth, immigration and movement of people. The expansion of trading routes between the interior and the coast, starting around 1300 years ago and intensifying in the eighteenth and nineteenth centuries CE, was one such process. These caravan routes possibly acted as conduits for spreading New World crops such as maize (Zea mays), tobacco (Nicotiana spp.) and tomatoes (Solanum lycopersicum), although the processes and timings of their introductions remains poorly documented. The introduction of southeast Asian domesticates, especially banana (Musa spp.), rice (Oryza spp.), taro (Colocasia esculenta), and chicken (Gallus gallus), via transoceanic biological transfers around and across the Indian Ocean, from at least around 1300 yr BP, and potentially significantly earlier, also had profound social and ecological consequences across parts of the region.

Through an interdisciplinary synthesis of information and metadatasets, we explore the different drivers and directions of changes in land-cover, and the associated environmental histories and interactions with various cultures, technologies, and subsistence strategies through time and across space in East Africa. This review suggests topics for targeted future research that focus on areas and/or time periods where our understanding of the interactions between people, the environment and land-cover change are most contentious and/or poorly resolved. The review also offers a perspective on how knowledge of regional land-use change can be used to inform and provide perspectives on contemporary issues such as climate and ecosystem change models, conservation strategies, and the achievement of nature-based solutions for development purposes.

In this study, Electrophoretic Deposition (EPD) technique was used to fabricate TiO2/Nb2O5 composite
thin films on FTO coated glass for application as photoelectrodes in Dye Sensitized Solar Cells (DSSC). A
TiO2/Nb2O5 ratio of 1:1 was used in a 2-propanol suspension solution with a solid loading of 0.25g/L. Optical
investigations showed that the film with thickness of 5.5 µm deposited at 35.0 V for 90.0 s had the highest
transmittance of 55.0 % at a wavelength (λ) of 1,300 nm. The optical band gap energy (Eg) was 3.884 eV and was
found to be dependent on the annealing time. The solar cell fabricated from this film had an open circuit voltage
(VOC) of 0.66 V, fill factor (FF) of 57.0%, short current density (JSC) of 5.25 mA/cm2 and photo conversion
efficiency (PCE) of 2.0%. Electrochemical Impedance Spectroscopy (EIS) analysis indicate that the DSSC device
with thinner photoelectrodes have more efficient electron transport in the photoanode compared to thicker
photoelectrodes to achieve higher conversion efficiencies.

The objective of the study is to determine the effect of job tenure on employees’ career mobility. The study used a descriptive survey and a population study of 169 employees with a response rate of 122(72.2%). Primary data was collected using self-administered structured questionnaires. Descriptive statistics was used to analyze the data and the hypothesis formulated was analyzed using linear regression analysis. The results confirmed the hypothesis that job tenure influences employee career mobility (R2=.141, F=19.77, P≤0.05). The correlation coefficient for the model was 0.376 which also confirms that there is a positive but weak relationship between length of service and career mobility. The study recommends that employees who have served and organization for long should be considered for promotion this brings about employees loyalty and commitment to the organization. The paper suggests that other variables can be added in terms of moderating and mediating variables to strengthen the model.

The Maasai pastoralists have in the past decade experienced disruptions as precipitation season shifts. These shifts have adversely affected their economies and livelihoods. Moreover, they have been losing up to 30 % of their herd annually to drought related disasters, yet the locals’ capacity on climate pattern shifts is inadequate. To address this gap, a study focused on Kajiado County due to its harboring large of livestock. The study aimed at determining the historical precipitation characteristics. To achieve this, the study utilized Climate Hazards group Infra-Red Precipitation with Stations data set (CHIRPS) for the period 1983-2014 for each of the five sub-counties within Kajiado County. The key findings, encompassed: declining trend in the average annual precipitation; shifting from the usual bi-modal rainfall seasons with March to May (MAM) experiencing worst failure compared to October to December (OND) and the shortening of the famine cycles.

Despite the potential of Learning Management System (LMS) supported asynchronous e-
learning to improve asynchronous e-learning system quality by enhancing learning
effectiveness and academic achievement of HEIs, several challenges are faced in the
process of providing the e-learning mode of study particularly in developing countries. The
study will explore five factors that influence quality of asynchronous e-learning: instructional
design, learner support, contextual factors, student characteristics and instructor
characteristics. The quality factors can be used to evaluate quality so as to monitor and
improve the inputs, processes and outputs of asynchronous e-learning systems. The study
examines existing e-learning literature and then proposes five factors that determine the
quality of e-learning systems.

International Journal of Education and Development using Information and Communication Technology. 2018;14(1): 152-163. Abstract

The purpose of the present study was to identify the influencing factors of asynchronous
elearning system quality particular in developing countries via a review of current literature
and a qualitative pre-study conducted at Jomo Kenyatta University of Agriculture and
Technology (JKUAT). Despite the perceived benefits of these systems to overcome
challenges facing education sector in the region, studies show that the majority of them have
not been successful. After a thorough review of existing literature on developing countries
and a qualitative pre-study conducted at JKUAT University, the study identified the factors
that influence quality of e-learning systems as: Course Design, Content support, social
support, and Student Characteristics, Instructor Characteristics, Technician Characteristics,
Course Assessment and Institutional factors.

Background: The annual global burden of stillbirths is approximately 2.6 million, 98% of which occur in Sub Saharan Africa, (WHO, 2015). In 2016, approximately 24 still births per month occurred in Mbagathi County Hospital (MCH) representing a 33.3% increase from 2015. A third of these were Fresh Still Births (FSBs) - (Mbagathi reproductive health report 2015/2016).
Objectives: To establish factors influencing increase in FSB among women delivering at MCH.
Methodology: The study was conducted at MCH postnatal ward. A descriptive cross sectional study design was employed. Forty three respondents with FSBs were consecutively sampled. Clearance to conduct the study was sought from Ethics Review Committee, MCH and respondents. Researcher administered questionnaires were used for data collection over two months. Descriptive data involved calculation of measures of central tendency. Findings were presented in tables, graphs and narrative.
Results: Majority of the respondents were less than 20 years old, had low education level and were unemployed. Majority had preterm deliveries; prolonged premature rupture of membranes had medical conditions and attended ANC less than four times. Majority of the FSBs had complications and were delivered preterm. The facility had inadequate staffing, lacked prompt triaging equipment, and rarely used partograph to monitor labor.
Conclusion: Maternal, fetal and hospital related factors influenced high prevalence of FSB.
Recommendations: Improving uptake of focused antenatal care among women. Girl child empowerment in line with Sustainable Development Goal 5. Improve staffing ratios, develop protocol regarding triaging and labor monitoring. Availing hospital equipment for proper maternity care.

Key words: Fresh still births, developing countries, risk factors, perinatal mortality.

Factors influencing male involvement on Antenatal Care among clients attending Antenatal clinic: A case of Kenyatta National Hospital, Kenya

Background: Male participation is a crucial component in the optimization of antenatal care services. Level of male participation has been found to be low. This study aimed to identify determinants of male partners’ involvement in antenatal care services.
Methods: A descriptive cross-sectional study was used. The study population included expectant women and available male partners at the antenatal clinic at Kenyatta National Hospital. A sample of 79 respondents was recruited into the study. Consecutive sampling was used to select the study participants. Data was collected using a semi structured questionnaire, analyzed using SPSS computer package version 20 and thereafter presented using descriptive methods.
Findings: Majority of participants (90%) were aged above 25 years, were more educated and had non-formal sources of employment. They knew at least 50% of the services offered and had a positive attitude towards ANC. Majority of participants (54%) stated that ANC is traditionally for women. Majority (77%) stated that the members of staff at ANC clinic are friendly and approachable.
Conclusions: Cultural beliefs and practices still hinder men’s participation as communities continue to uphold patriarchal tendencies that disregard women. Men’s attitude also determined their participation.

Study region

the Turkwel river basin, Kenya experiences a high level of water scarcity due to its arid climate, high rainfall variability and rapidly growing water demand.
Study focus

Climate change, variability and rapid growth in water demand pose significant challenges to current and future water resources planning and allocation worldwide. In this paper a novel decision-scaling approach was applied to model the response of the Turkwel river basin’s water resources system to growing demand and climate stressors. A climate response surface was constructed by combining a water resource system model, climate data, and a range of water demand scenarios.
New hydrological insights

The results show that climate variability and increased water demand are each important drivers of water scarcity in the basin. Increases in water demand due to expanded irrigation strongly influences on the resilience of the basin’s water resource system to droughts caused by the global climate variability. The climate response surface offers a visual and flexible tool for decision-makers to understand the ways in which the system responds to climate variability and development scenarios. Policy decisions to accelerate water-dependent development and poverty reduction in arid and semi-arid lands that are characterised by rapid demographic, political and economic change in the short- to medium term have to promote low-regrets approaches that incorporate longer-term climate uncertainty.
