Certain indigenous foods commonly consumed by Kenyan vulnerable groups (the malnourished; children under 5 years of age; pregnant and lactating women; malnourished adults in cases of vitamin or mineral deficiencies, TB, diabetes, cancer, AIDS; refugees; orphans the elderly and the disabled) are not yet evaluated for phenolic content and health relevant functionality. The present study was therefore designed to analyze the phenolic content, antioxidant and antidiabetic properties of methanolic extract of raw and traditionally processed food ingredients. The total phenolic contents of the cereals, legumes, oil seeds and vegetables were ranged from 0.41 to 3.00 g/100 g DM. Amaranth grain (Amaranthus cruentus) and drumstick leaves (Moringa oleifera) exhibited significantly higher phenolic content than the other samples. The methanolic extract of the investigated samples showed promising levels of DPPH radical scavenging activity (81–89%); ferric reducing/antioxidant power (FRAP, 44–744 mmolL−1 Fe[II]/g extract DM); α-amylase (10–45%) and α-glucosidase (13–80%) inhibition activities. The food ingredients with high phenolic content exhibited relatively higher antioxidant and antidiabetic activities. The results indicate that soaking + cooking is the mild processing method to preserve the phenolic compounds and their health relevant functionality in the presently investigated cereal, legume and oil grains, while cooking is suitable treatment for vegetables.

Indalo DM. Factors Affecting Patients Retention And Defaulter Rates In An Anti-retroviral Therapy Program.; Submitted. Abstract

The purpose of this research was to determine patients' retention and associated factors in the Antiretroviral Therapy (ART) program. Specifically, it establishes factors that contribute to patients' retention and recommends the appropriate strategies that enhance sustainable retention of patients in the ART program. The case studies were carried out at Kibera Community Based Health Care project/clinic - AMREF intervention area in Kibera slum
A descriptive cross-sectional method was employed aimed at collecting information from the patients in the program through random sampling, while stratified sampling was used to pick on defaulters, who were traced by Community Health Workers as well as key informants. A representative sample constituted 357 patients in the ART program, 27 defaulters and 8 Health Care Providers of the total population of patients in the program. Quantitative data was collected using a standardized questionnaire administered to the study participants in the program and defaulters. Qualitative data
was obtained through; focus Group Discussion and Key informants interviews. Ethical consideration and risk to human subjects was put into consideration, through provision of willing consent and confidentiality upheld at all times.
The study reveals that AMREF in Kenya, Kibera project continues to playa leading role in the fight against HIV/AIDS. A majority of the respondents (69%) confirmed to have disclosed their HIV status to someone while 31% were categorical that they have not disclosed their status to anyone. It is imperative to point out that disclosure levels were high (88%) amongst respondents in the 51-55 years age group and closely followed by those in the 41-45 years age group (77%). The study also found out that 49.5% of the respondents were on the affirmative that indeed they find it easy discussing their challenges with their clinicians, while 50.5% noted that they do not find it easy. It is
interesting to observe that the challenges of side effects related to ARV are more pronounced amongst those who skip appointments at the clinic compared to stigma and lack of food. A considerable number (15%) of the respondents noted that they like the clinic as it provides free ARVs while 4% lauded the good counseling services offered at the clinic. Some 3% liked the facility as it was near to their areas of residence. Asked to state the reasons why they would prefer other ART clinics, most of the respondents (63%) pointed to the distance from their areas of residence, 14% made reference to the quality of services while 8% explained that they would prefer other clinics if they offer food supplements as part of the program.
In conclusion psycho-social counseling appeared the most preferred service in the facility, it enforces adherence to medication and also reduces stigma related condition among the patients and those around them. MSF Belgium clinics were most preferred clinic in Kibera slum; AMREF Kibera project management should consider exchange visits to their sites and learn from each other. The study detects that there is a cross cutting call from the study approach that an ideal ART programme should provide comprehensive care and support (37%) and offer free medical care (15%) to enhance
accessibility besides integrating PTC (7%) among others as captured from the interviews with defaulters. Service delivery it was suggested should also be done professionally without unethical and coercive practices such sexual harassment among other malpractices that accentuate default.
AMREF Kibera project should consider to networking and collaborating with other organizations that are working in informal settlement to learn and share best practice to enhance adherence to ART care. Address the attitude of health care providers in the facility through trainings, supervision and assessment of care. The project should also review its approach to ART care and through operation research to boost ART care in marginalized communities in the informal settlements.

Ikiara GK. "Political economy of cash transfers In Kenya.". Submitted. AbstractWebsite

As a result of socio-economic and political challenges facing Kenya: 46% of the country‟s 38 million people are living below the poverty line; there are a rapidly growing number of orphans and vulnerable children - half of which have resulted from a HIV/AIDs pandemic which has hit the country in the last two decades; frequent droughts, and the recently unprecedented post-election violence following the disputed 2007 general elections, social protection programmes for the country‟s poor and vulnerable population have become increasingly important both economically and politically.
This study, using data and information obtained from government and donor representatives closely involved with Kenya‟s CT programmes and secondary data, examines Kenya‟s Social Protection Programmes with special focus on CT programmes.
Starting with a brief review of the prevailing poverty and economic conditions and challenges facing the country, the paper examines government attitude and attention towards Cash Transfer (CT) and non-cash social protection programmes; the evolution, coverage and other features of the existing CT programmes in the country; the roles of the government and development partners in the programmes; domestic and external influences in the establishment of the various social protection programmes; estimated costs of the required CT programmes and the affordability and sustainability of the programme in view of the prevailing economic conditions and capacities; and the political economy and the overall ownership of the implementation of CT programme in the country.
While Kenya has had a long history of implementation of non-cash transfer programmes, such as: food relief in the drought stricken areas; emergency and special programmes; school bursaries for needy children, and a wide range of other interventions, CTs are new, mainly in their pilot or early stages and have been in existence only in the last 5 years.
The existing CT programmes have a limited coverage of the targeted members in three programmes, viz the Orphans and Vulnerable Children (OVC), the Elderly and the Hunger Safety Net programme. With the on-going discussions to finalise the country‟s Policy on Social Protection and the Social Protection Strategy (2009-2012) and a large increase in government‟s financing of the CT programmes through national budget, the national coverage of these programmes is expected to rise substantially by 2012.
There are high prospects of enhancing and institutionalising CT and non-CT social protection programmes in the country‟s budgetary system in view of the broad political support the programmes have received from a wide spectrum of political actors in the country. The liberalisation of the country‟s political system in 1992 which ushered in a highly vibrant and competitive multi-party political environment, has favoured introduction and expansion of social protection initiatives, both cash and non-cash.
A number of donors, notably UNICEF, DFID, World Bank and SIDA played key technical and financial roles in the establishment of CT programmes in the country creating the perception that the programmes were donor driven and that the government was more in favour of non-cash interventions. With increasing government and public appreciation of CT programmes as an appropriate tool for reaching more effectively a special group of the population the extremely poor or hard-core poor, who cannot participate in productive economic activities, the government participation in financing the programmes has risen dramatically, in the last two years. The government is expected to shoulder the bulk of the required resources for these programmes in the coming years but with supplementary resources from willing development partners.
There is considerable consensus among the stakeholders that the CT programmes are affordable and sustainable even without external donors, so long as the programmes are expanded gradually, taking into account the capacity of the national economy to support the programmes at various levels. The successful implementation of much larger non-cash social protection programmes such as the Free Primary Education for 8 million pupils and Free Day Secondary Education and the Constituency Development Fund are generally taken as good indicators of the ability of the country to sustain CT programmes as long as political will is there.
Most of the stakeholders were of the view the CT programmes are too socially and politically sensitive to be heavily dependent on external support which was often determined by exogenous factors beyond the government‟s control.
Kenya‟s draft National Social Protection Strategy, estimates that the country could escalate the Cash Transfer Programme nationally to cover all the extremely poor consisting of the People with Disabilities (PWD), Orphans and Vulnerable Children (OVC), and Households with Older Persons above 65 years, at a total cost of approximately Ksh 12 billion annually (about 3.3% of the national budget), at a monthly cash “transfer” of Ksh 1,000 per household.

To determine the magnitude and pattern of significant refractive errors in primary school children in Kilungu division of Makueni District, Kenya. Design: A cross – sectional primary school based study. Setting: Eight (8) Primary school in Kilungu division of Makueni District, Kenya. Target population: 1439 Primary school pupils aged between 12 and 15 years. Results: The prevalence of significant refractive error was 5.2%, 75/1439, (95% CI) being responsible for 92.6 % of all causes of poor eyesight. Hypermetropia accounted for 3.2% (95% CI), myopia 1.7% (95% CI) and astigmatism 0.3% (95% CI) of refractive errors. Myopia was more likely to be present in the pupils aged 14 to 15 years than those aged 12 to 13 years with OR 2.9 (0.1 – 9.2) which was statistically significant (p = 0.022). Conclusion: The overall prevalence of significant refractive errors in pupils aged 12 to 15 years in Makueni's Kilungu division at 5.2% (95% CI) was high enough to justify a regular school eye screening in primary schools in Kenya.

Missiame A, Irungu P, Nyikal RA, Appiah-Kubi GD. ""Adoption of rural bank credit programs among smallholder farmers in Ghana: an average treatment effect estimation of rates of exposure and adoption and their determinants"." gricultural Finance Review. 2021. AbstractWebsite

Purpose
The study aims to estimate the rates of exposure to, and adoption of, rural bank credit programs by smallholder farmers in rural Ghana and the factors responsible for those rates.

Design/methodology/approach
The study used a random sample of 300 smallholder farmers in the Fanteakwa District of Ghana, obtained through the multistage sampling technique. The study also employed the average treatment effects approach to estimate the average treatment effect of farmers’ exposure to rural bank credit programs, on their adoption of such programs.

Findings
The actual adoption rate is approximately 41%, and the potential, conditional on the whole population being aware of rural bank credit programs, is approximately 61%. Accordingly, there is a gap of about 20% in the adoption of rural bank credit programs, and is due to the incomplete exposure of smallholder farmers to the rural bank credit programs. Age of the household head, access to extension services, membership in farmer-based organizations and active savings accounts with a rural bank are the major contributors to smallholder farmer exposure to and the adoption of rural bank credit programs.

Originality/value
The current study is the first of its kind to be conducted in Ghana on rural bank credit programs. It takes into account the extent to which smallholder farmers are exposed to such credit programs and how it influences their decisions to access or adopt.

"Antimicrobial resistance profiling and phylogenetic analysis of Neisseria gonorrhoeae clinical isolates from Kenya in resource limited setting." Frontiers in Microbiology. 2021. AbstractWebsite

Background: Africa has one of the highest incidences of gonorrhea. Neisseria gonorrhoeae is gaining resistance to most of the available antibiotics, compromising treatment across the world. Whole-genome sequencing (WGS) is an efficient way of predicting AMR determinants and their spread in the population. Recent advances in next-generation sequencing technologies like Oxford Nanopore Technology (ONT) have helped in the generation of longer reads of DNA in a shorter duration with lower cost. Increasing accuracy of base-calling algorithms, high throughput, error-correction strategies, and ease of using the mobile sequencer MinION in remote areas lead to its adoption for routine microbial genome sequencing. To investigate whether MinION-only sequencing is sufficient for WGS and downstream analysis in resource-limited settings, we sequenced the genomes of 14 suspected N. gonorrhoeae isolates from Nairobi, Kenya.

Methods: Using WGS, the isolates were confirmed to be cases of N. gonorrhoeae (n = 9), and there were three co-occurrences of N. gonorrhoeae with Moraxella osloensis and N. meningitidis (n = 2). N. meningitidis has been implicated in sexually transmitted infections in recent years. The near-complete N. gonorrhoeae genomes (n = 10) were analyzed further for mutations/factors causing AMR using an in-house database of mutations curated from the literature.

Results: We observe that ciprofloxacin resistance is associated with multiple mutations in both gyrA and parC. Mutations conferring tetracycline (rpsJ) and sulfonamide (folP) resistance and plasmids encoding beta-lactamase were seen in all the strains, and tet(M)-containing plasmids were identified in nine strains. Phylogenetic analysis clustered the 10 isolates into clades containing previously sequenced genomes from Kenya and countries across the world. Based on homology modeling of AMR targets, we see that the mutations in GyrA and ParC disrupt the hydrogen bonding with quinolone drugs and mutations in FolP may affect interaction with the antibiotic.

Conclusion: Here, we demonstrate the utility of mobile DNA sequencing technology in producing a consensus genome for sequence typing and detection of genetic determinants of AMR. The workflow followed in the study, including AMR mutation dataset creation and the genome identification, assembly, and analysis, can be used for any clinical isolate. Further studies are required to determine the utility of real-time sequencing in outbreak investigations, diagnosis, and management of infections, especially in resource-limited settings.

Ikua MD, Wambua BN, Omoke KJ. "Constraints and Opportunities for Greenhouse Farming Technology as an Adaptation Strategy to Climate Variability by Smallholder Farmers of Nyandarua County of Kenya." East Africa Journal of Science,Technology & Innovation. 2021;2(Special ). Abstract

Nyandarua County of Kenya has been for a long time, manifested itself as one of the major food baskets in the country. This is because of its high and sustainable output in crop farming i.e., maize, Irish potatoes, wheat, and other horticultural crops like vegetables and fruits. However, this scenario has recently changed because the usual high crop output has not been forthcoming due to recent changes in climatic patterns where rainfall has become very unreliable and temperatures very extreme. In an attempt to adapt to this climate variability and its associated negative impacts on crop farming, smallholder farmers have tried to apply the greenhouse farming technology for them to be able to maintain and or improve the various crop output amid the climatic changes. The study aims to examine and assess the socio-economic determinants and constraints associated with this attempt of adaptation strategy. Using the primary data of 300 respondents (Smallholder farmers) in the County, the study adopted a logistic regression analysis model to associate the demographic, socio-economic, and constraints encountered by the smallholder farmers with the adoption of the greenhouse farming technology. The study results indicate that this adaptation strategy was reported by 25 out the 300 smallholder farmers (5.83%). The study results further suggest that financial constraints (27%) and lack of information (22.3%) are the major constraints preventing smallholder farmers from effectively adopting this adaptation strategy. However, the probability results of logistic regression analysis (68%) indicate that if properly adopted, the method can provide a solution to the currently reduced food shortages and increase food security among the smallholder farmers of Nyandarua County of Kenya.

Ipara BO, Nyikal R, Otieno DJ, Makokha NS. "The contribution of extensive chicken production systems and practices to Newcastle disease outbreaks in Kenya.". 2021. AbstractWebsite

Newcastle disease (ND) poses a challenge especially for farmers rearing indigenous chicken under the extensive system. This is due to the lack of uniformity in practices, favoring the introduction and spread of the disease. This is worsened by the lack of information on how management practices contribute to the spread of ND. The current study assessed the role of extensive chicken production systems and management practices on the frequency of ND outbreaks in Kenya using a Poisson regression model (PRM) on primary survey data from 332 farmers in Kakamega and Machakos counties. Descriptive results showed a low access to institutional support services like extension, training, credit, and vaccination services for both male and female farmers. Results from the PRM analysis show that flock size, isolated and confined housing, multi-aged flock mixture, screening of birds, access to ND vaccination, ND awareness, distance to agro-veterinary service providers, and access to animal health training and extension services had significant effects on the frequency of ND outbreaks. The findings underscore the need for innovative extension approaches that facilitate the use of information communication technologies to create more awareness on disease detection and mitigation measures. Use of farmer groups as innovation platforms for enhanced skill sharing and as key peer monitoring channels would also improve compliance with prescribed disease control methods. Further, there is a need for partnerships between local-level county governments, vaccine producers, and agro-veterinary service providers to ensure the development of low-cost vaccines and requisite storage facilities, and their timely delivery to the male and female resource-poor smallholder extensive chicken farmers.

This paper investigates the effect of FDI on performance of manufacturing firms in
Kenya. Little is documented about the link between FDI variables of capital flow,
advanced production technology, marketing expertise and management know-how
and performance of firms. The study’s sought to establish the effect of each
individual FDI variables on firm’s performance. It also sought to established the
overall effect of the performance manufacturing firms in Kenya. The population of
study comprised 100 companies registered with Kenya Association Manufacturing
as at the time of data collection in 2019 and that had over 10 percent foreign
ownership. The respondents were the CEOs of organization. The study used a
structured questionnaire to collect primary data. Descriptive and inferential
statistics were both used to analyze the data. Data was pretested for normality,
linearity, multicollinearity, autocorrelation and homoscedasticity and the data found
to meet most of these preconditions. The Pearson correlation analysis was employed
to discern not only the strength but also the direction of the interrelationships
involving the variables. The researcher tested the effect of the components of FDI
on performance of manufacturing firms. The study developed one hypothesis and
four sub hypothesis. The results revealed that there was a statistically significant
relationship between FDI and firm performance. This imply that to achieve better
firm performance, the government need to come up with policies geared to
attracting more FDI into the key sectors of the economy.

Abstract
Background: There are still concerns over the safety of laparoscopic surgery in coronavirus disease 2019 (COVID-19) patients due to the potential risk of viral transmission through surgical smoke/laparoscopic pneumoperitoneum.

Methods: We performed a systematic review of currently available literature to determine the presence of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) in abdominal tissues or fluids and in surgical smoke.

Results: A total of 19 studies (15 case reports and 4 case series) comprising 29 COVID-19 patients were included. The viral RNA was positively identified in 11 patients (37.9%). The samples that tested positive include the peritoneal fluid, bile, ascitic fluid, peritoneal dialysate, duodenal wall, and appendix. Similar samples, together with the omentum and abdominal subcutaneous fat, tested negative in the other patients. Only one study investigated SARS-COV-2 RNA in surgical smoke generated during laparoscopy, reporting negative findings.

Conclusions: There are conflicting results regarding the presence of SARS-COV-2 in abdominal tissues and fluids. No currently available evidence supports the hypothesis that SARS-COV-2 can be aerosolized and transmitted through surgical smoke. Larger studies are urgently needed to corroborate these findings.

Abstractmediating_role_of_absorptive_capacity_on_the_relationship_between_foreign_direct_investment_and_local_firms_performance.pdf

There is little documentation on the role of absorptive capacity on the relationship between FDI and performance of firms. This paper investigates the mediating role of absorptive capacity on the relationship between FDI and performance of manufacturing firms in Kenya. The population of study comprised 100 companies registered with Kenya Association of Manufacturers that had over 10 percent foreign ownership as at the time of data collection in 2019. The respondents were the CEOs of organization or their designated officers. The study used a structured questionnaire to collect primary data. The respondent were required to indicate how the introduction of FDI impacted on organizations capital flow, advanced production technology, marketing expertise and management knowhow. They were also to indicate the extent their Organisation had invested in absorptive capacity and the effect absorptive capacity had on the relationship between FDI and local firm performance. Descriptive and inferential statistics were both used to analyze the data. The results revealed that absorptive capacity has statistically significant mediating effect on the relationship between FDI and firm performance. This imply that an incremental change in the absorptive capacity would generate growth in company’s performance. As such Kenyan and other sub-Sahara African countries government need to come up with polices geared to supporting improvement of firms absorptive capacities so as to spur the growth of their key sectors of the economy.

Abstract

Aim: Certain edible plant sources contain vegetable oils that have been under-exploited both commercially and in research. This study aimed to determine the physicochemical properties, fatty acids composition, and antioxidant potential of the oil from the seed kernels of Telfairiapedata, which are used as food by the local population of Tharaka-Nithi County in Kenya.

Materials and Methods: Telfairia pedata seeds were collected from farmers in the county of Tharaka-Nithi, Kenya. n-Hexane was used to extract the oil via soxhlet extraction. Standard laboratory protocols were used to characterize the oil’s physicochemical properties, while fatty acids composition and antioxidant potential were characterized using gas chromatography mass spectrometry and 2, 2-diphenyl-1-picrylhydrazyl assay, respectively.

Results: The seed kernels of Telfairia pedata yielded more than 66% of oil. The oil’s physicochemical properties were found to be within the Food and Agriculture Organization set limits and were as follows; moisture content (0.0592±0.0140%), peroxide value (0.9641±0.2021 meq O2/Kg), iodine value (23.0058±2.2473 gI2/100g) and acid value (0.6352±0.0330 mg KOH/g). Fatty acids such as myristic acid (14:0; 0.11%), palmitoleic acid (16:1n7; 0.13%), palmitic acid (16:0; 34.97%), margaric acid (17:0; 0.10%), linoleic acid (18:2n6; 48.46%), stearic acid (18:0; 15.33%), 10,13-octadecadienoic acid (18:2n5; 0.09%), 18-methylnonadecanoic acid (20:0; 0.68%), and behenic acid (22:0; 0.14%) were found in the oil. The antioxidant potential of the oil expressed in IC50 was found to be 18.05 mg/mL, in relation to that of ascorbic acid 2.406 mg/mL.

Conclusions: Telfairia pedata seed kernel oil can be economical to exploit commercially due to its relatively high yield. The determined properties of Telfairiapedata seed kernel oil present high nutritive value making the oil fit for edible applications.

Abstract
This paper assesses the impact of access to credit from rural and community banks (RCBs) on the technical efficiency of smallholder cassava farmers in Ghana. The study employed the stochastic frontier, and endogenous switching regression models to estimate the technical efficiency, and the impact of RCB credit access, respectively, on a randomly selected sample of 300 smallholder cassava farmers in the Fanteakwa District of Ghana. Results suggest that cassava farmers in the District are 70.5 percent technically efficient implying that cassava yield levels could be increased further by 29.5 percent without changing the current levels of inputs. The results further reveal that the gender of the household head, access to extension services, membership in farmer organizations, and proximity to the bank are the major factors that positively influence farmers to access credit from RCBs. On average, farmers who accessed credit from RCBs have significantly higher technical efficiencies than farmers who did not access, suggesting that access to credit from RCBs positively impacts the technical efficiency of smallholder cassava farmers.

Keywords: Credit access; Endogenous switching regression; Rural and community banks; Stochastic frontier model; Technical efficiency.

Abstract
The African Great Lakes (AGL) have rich fisheries and are renowned “biodiversity hotspots”. Consequently the AGLand the ecosystem services they provide, underpin the welfare and livelihoods of over 50 million people across 10 countries. Despite the recognized importance of the AGL, these vital ecosystems and their livelihood support systems are threatened by numerous anthropogenic stressors at local, regional, and global scales. Past and continued efforts to address critical challenges on these lakes are often short-term, parochial, disparate, and uncoordinated resulting in a lack of comprehensive and comparable scientific data and inadequate resources to influence evidence-based policy. Over the past two decades, several international workshops, conferences and scientific publications have identified the need for collaboration, knowledge sharing, and harmonization of research and management as key elements to enhance conservation efforts in the AGL. In this commentary, we introduce the African Center for Aquatic Research and Education (ACARE), which aims to strengthen research and provide the scientific evidence needed to make informed decisions related to sustainable fisheries and aquatic resource management in the AGL. To do this, ACARE will administer a highly collaborative network of experts with three long-term goals: (1) strengthen global and regional research partnerships; (2) establish transboundary and inter-jurisdictional lake advisory groups; and (3) build capacity of freshwater scientists through experiential education and public engagement.

This paper analyzes the socio-economic characteristics of households that affect husbands and wives' contributions to decisions regarding the use of income from crop and livestock sales in Kenya. Using a sample of 276 households, we apply a multinomial logit model to assess factors affecting decision-making. Results show that husbands make most decisions concerning agriculture, while wives mainly decide on daily household expenditure. Higher education levels were found to increase women's involvement in decision-making on income use. Group membership had a positive effect on joint decision-making on income use. The study recommends improving women's access to education, which will improve their access to productive resources, hence their decision-making power. Providing incentives for members of agricultural groups can provide avenues for learning. Gender-transformative approaches that empower women and sensitize men to allow space for women to engage in decision-making, can have an impact in improving the decision-making capacity of women in households.

In this paper analysis of contribution of macroeconomic variables gross domestic product (GDP), external debt (ED), foreign direct investment (FDI), private investment (PI), youth population (POP), and youth literacy rate (LR) to youth unemployment(YUN) in Kenya over time is done. The analysis is done under framework of cointegration of time series data. First, logarithmic transformation of the series is carried out followed by stationarity test to determine the order of stationarity. The Philip-Ouliaris cointegration test is carried out to determine whether the series are individually cointegrated in a pair-wise manner. Then the Johansen cointegration test is conducted to determine the rank of cointegration. The paper does not proceed to identify cointegration relations as that is superfluous as far as estimation of linear cointegration model is concerned. Finally the linear cointegration equation of the macroeconomic variables is estimated and interpreted. Philip-Ouliaris test reveals that six pairs are I(0) while 15 pairs are I(1). The Augmented Dickey-Fuller test finds that GDP, FDI, and ED are stationary at level, i.e. without differencing whereas PI, LR, YUN, and POP are stationary of first difference. According to Johansen cointegration test, the rank of cointegration is 3, revealing three cointegration relations among the variables used. The results indicate that 1% increase in GDP, ED, FDI, and LR increases YUN by 0.356204%, 0.269%, 0.002441%, and 0.154216 respectively.

Description
Introduction:
Reports of emergence of Artemisinin Combination Therapies (ACTs) resistant malaria parasites in Greater Mekong region and Equatorial Guinea, is a strong reason necessitating increased efforts to discover new antimalarial compounds with novel mechanisms of action. Plants have potential to yield new antiplasmodial compounds. This study investigated the safety and efficacy of three plants; Bersama abyssinica Fresen, Rubus keniensis Standl and Hypoestes verticillaris (Lf) Sol. ex Roem. and Schult that are used by the Ogiek community of Kenya for treatment of malaria.
Methodology:
The crude extracts were tested for in vitro antimalarial activity using Plasmodium falciparum strains W2 (chloroquine resistant) and D6 (chloroquine sensitive). Safety evaluation was done using monkey kidney Vero cells and the brine shrimp lethality test.
Results:
Dichloromethane: methanol (1: 1) and 5% aqueous methanol extracts of the three plants exhibited in vitro antiplasmodial activity against the W2 and D6 Plasmodium falciparum strains with IC50= 12.11–19.18 µg/mL, 5.46-7.04 µg/mL and 9.82–34.52 µg/mL, respectively. H. verticillaris extracts were the most active against the two Plasmodium falciparum strains. The dichloromethane: methanol extracts of the three plants exhibited lower toxicity on monkey kidney Vero cells relative to antiplasmodial activity as compared to the 5% aqueous methanol extracts. The mean Vero cells: parasite selectivity index of the dichloromethane: methanol extracts was (4.8), B. abyssinica (3.75) and R. keniensis (1.9), while for the 5% aqueous methanol extracts they were H. verticillaris (1.0), B. abyssinica (1.95 …

Abstract:

This study reports the biosynthesis of narrow range diameter silver nanoparticles at optimum conditions using Eucalyptus corymbia as a reducing and stabilizing agent. Optimal conditions for biosynthesis of silver nanoparticles (AgNPs) were found to be; an extraction temperature of 90°C, pH of 5.7 a Silver Nitrate concentration of 1mM and AgNO3 to plant extract ratio of 4:1. UV-Visible spectroscopy monitored the formation of colloidal AgNPs. The UV-Visible spectrum showed a peak around 425 nm corresponding to the Plasmon absorbance of the AgNPs. The size and shape characterization of the AgNPs was done using Transmission Electron Microscopy (TEM) techniques which revealed narrow range diameter (18-20 nm), almost monodispersed AgNPs, spherical in nature and with minimal agglomeration. Energy Dispersive X-ray (EDX) results showed the presence of two peaks at 3.0 and 3.15 keV in the silver region. The Fourier Transform Infrared-Spectra (FTIR) of the plant extract and the AgNPs gave rise to vibrational peaks at 3260 and 1634 wavenumbers which are due to the presence of OH and –C=C-functional groups respectively.

Kamau F, Strijdom H, Mwangi P, Blackhurst D, Imperial E, Salie R. "Antiretroviral drug-induced endothelial dysfunction is improved by dual PPARα/γ stimulation in obesity.". 2019;121:106577. AbstractWebsite

Obesity rates are rising in HIV-infected populations; however, the putative role of highly active antiretroviral therapy (HAART) in the development of endothelial and cardiovascular derangements in the presence of pre-existing overweight/obesity is unclear. Although dual peroxisome proliferator-activated receptors-alpha/gamma (PPARα/γ) stimulation mitigates HAART-induced metabolic dysfunction, vascular effects are unresolved. To investigate whether HAART induces vascular dysfunction in obesity and to explore the underlying mechanisms of PPARα/γ stimulation, male Wistar rats were placed on a high-calorie diet for 16 weeks. After 10 weeks, HAART (lopinavir/ritonavir, azidothymidine/lamivudine) with/without PPARα/γ agonist, Saroglitazar, was administered daily for six weeks. Excised thoracic aorta rings were subjected to isometric tension studies and Western blot measurements. HAART+Saroglitazar-treated obese animals recorded lower adiposity indices (4.3 ± 0.5%) vs. HAART only-treated obese rats (5.6 ± 0.3%; p < .01). Maximum acetylcholine-induced vasorelaxation (Rmax), was lower in obese+HAART group (76.10 ± 3.58%) vs. obese control (101.40 ± 4.75%; p < .01). However, Rmax was improved in obese+ HAART+Saroglitazar (101.00 ± 3.12%) vs. obese+HAART rats (p < .001). The mean LogEC50 was improved in obese+HAART+Saroglitazar vs. obese+HAART group; p = .003. Improved endothelial function in obese+ HAART+Saroglitazar group was associated with upregulation of eNOS, PKB/Akt and downregulated p22-phox expression vs. obese+HAART group. Therefore, PPARα/γ stimulation attenuated HAART-induced endothelial dysfunction by upregulating vasoprotective eNOS, PKB/Akt signaling and downregulating pro-oxidative p22-phox expression.

In developing countries, chicken trade is characterized by complex chains comprising of many actors with limited biosecurity. This increases the spread of chicken diseases like Newcastle disease (ND). In Kenya, there is lack of uniformity in practices used in live bird markets, leading to increased disease outbreaks. This study aimed at assessing the effects of the chicken marketing practices on the frequency of ND outbreaks. A Poisson regression (PRM) was used on data collected from 336 traders selected using multi-stage sampling in Kakamega, Machakos, and Nairobi. Results highlight the low access of trainings and credit by traders. From the PRM results, breed composition, market channel, transportation, origin of birds, mixing of birds, slaughter of birds, disposal of waste, and housing as well as trader attributes like ND awareness, licensing, gender, and age had significant effects on the frequency of ND outbreaks. The study recommends that County governments collaborate with development partners to develop innovative ways of disseminating information on ND. The County governments should invest in market infrastructure such as slaughter facilities, special shelters and waste disposal equipment. There is also need for enforcement of biosecurity and hygiene measures through regular market inspections.

Ismail LW, ZP Q, SB O. "The acceptability of HIV testing among women receiving post abortion care." South Sudan Medical Journal. 2019;12(3):101-105. AbstractWebsite

Introduction: In South Sudan few women have heard about the HIV. The prevalence of HIV infection in the country is 2.6%. Post abortion care (PAC) accounts for over 50% of all gynaecological admissions at the Juba Teaching Hospital (JTH). HIV testing is not routinely offered as part of PAC services.

Objective: To determine factors associated with acceptability of HIV testing among women receiving PAC at JTH.

Methods: This was a cross-sectional study, conducted at the Gynaecological Unit of JTH. Three hundred and forty patients were interviewed using a structured questionnaire.

Results: The mean age of the participants was 24.7 years with 50.5% aged <25years, 31.5% were employed, and 31.8% had no formal education. Acceptability of HIV testing was 70.9% and the prevalence of HIV was 2.7%. The most common reason for not accepting, was the belief, based on previous results, that they were HIV negative. Patients aged ≥25 years and those with primary and secondary education were twice as likely to accept HIV testing than those <25 years and those with no formal education, respectively. Employment status, religion and marital status were not statistically associated with acceptability of HIV testing. Patients previously tested for HIV were more likely to accept testing.

Conclusion: Routine HIV testing should be integrated into PAC services with efforts to increase awareness of HIV and importance of testing

Introduction Knowledge of anatomical variations in the origin and in the course of the dorsal metatarsal arteries (DMTAs) is valuable for many procedures, including reconstructive surgeries and flap selection. However, there is a paucity of data on these arteries among black Africans. Materials and Methods The present study studied the origin and the location of DMTAs in 30 formalin-fixed cadaveric feet of adult black Kenyans at the Department of Human Anatomy of the University of Nairobi, Nairobi, Kenya. Results Dorsal metatarsal arteries were present in all of the cases. Of the right dorsalis pedis artery (DPA), in the majority of the cases, the 1st DMTA arose as the continuation of the DPA, while the 2nd to 4th DMTAs were given off as branches from the arcuate artery (AA). On the left feet, in the majority of the cases, the 1st DMTA arose as the continuation of the DPA, while the rest were given off as branches from the AA. In relation to the dorsal interossei muscles, all of the the arteries were either within the muscle fibers (53%) or beneath them (47%), on the right side. On the left side, the 1st DMTA was above the muscles in 40% of the cases; within the muscles in 53%; and beneath the muscles in 7%. The 2nd and 3rd DMTAs were above the muscles in 57% and in 53% of the cases, respectively. Conclusion These results reveal that the DMTAs show variation in their origin and position relative to the dorsal interossei muscles. These variations display bilateral asymmetry.

In this paper we consider cointegration analysis in an autoregressive distributed lag (ARDL) structure. First, logarithmic transformation is performed on the series to reduce outlier effects and have elasticity interpreted in terms of percentage. Second, the variables are tested for stationarity using Augmented Dickey-Fuller test. Third, the Johansen Cointegration test is carried out to examine cointegration of the series. Fourth, cointegrated dynamic ARDL model is estimated using ordinary least squares (OLS) and effects of variables and their lags interpreted. The results indicate that Gross Domestic Product (GDP) and its two-year lag are the only ones having negative effect on youth unemployment, that is, one unit increase in GDP and GDP two-year lag reduce youth unemployment by 0.207922% and 0.2052705% respectively. Also, one unit increase in External Debt (ED) and ED two-year lag reduce youth unemployment by 0.07303% and 0.009116% respectively. Furthermore, unit increase in one-year lag of youth literacy rate is the only one which reduces youth unemployment by 0.0892691%; one-year and three-year lag of population (POP) reduce youth unemployment by 0.2590455% and 4.3093119% respectively. The Foreign Direct Investment (FDI) and Private Investment (PI) do not have significant effects on youth unemployment. In the long run, increase in GDP causes increase in youth unemployment by 0.09148447%. The long run result explains that GDP growth in the country is “jobless growth” mainly in less labour intensive sectors.

Generalized hyperbolic distribution and some of its subclasses like normal, hyperbolic and variance gamma distributions are used to fit daily log returns of eight listed companies in Nairobi Securities Exchange and Montréal Exchange. EM-based maximum likelihood estimation procedure is used to estimate parameters of the model. Kernel densities and empirical distribution of data are compared. The goodness of fit statistics of proposed distributions are used to measure how well model fits the data. Empirical results show that Generalized hyperbolic Distribution seems to improve partially, the geometric Brownian assumption on modeling returns of the underlying process, both in a developed and emerging market. Both markets seem to have different stochastic time

BJOG: An International Journal of Obstetrics & Gynaecology.. 2019;127(5):628-634. AbstractWebsite

Objective: To assess the maternal characteristics and causes associated with refractory postpartum haemorrhage (PPH).

Design: Secondary analysis of the WHO CHAMPION trial data.

Setting: Twenty-three hospitals in ten countries.

Population: Women from the CHAMPION trial who received uterotonics as first-line treatment of PPH.

Methods: We assessed the association between sociodemographic, pregnancy and childbirth factors and refractory PPH, and compared the causes of PPH between women with refractory PPH and women responsive to first-line PPH treatment.

Main outcome measures: Maternal characteristics; causes of PPH.

Results: Women with labour induced or augmented with uterotonics (adjusted odds ratio [aOR] 1.35; 95% CI 1.07-1.72), with episiotomy or tears requiring suturing (aOR 1.82; 95% CI 1.34-2.48) and who had babies with birthweights ≥3500 g (aOR 1.33; 95% CI 1.04-1.69) showed significantly higher odds of refractory PPH compared with the reference categories in the multivariate analysis adjusted by centre and trial arm. While atony was the sole PPH cause in 53.2% (116/218) of the women in the responsive PPH group, it accounted for only 31.5% (45/143) of the causes in the refractory PPH group. Conversely, tears were the sole cause in 12.8% (28/218) and 28% (40/143) of the responsive PPH and refractory PPH groups, respectively. Placental problems were the sole cause in 11 and 5.6% in the responsive and refractory PPH groups, respectively.

Conclusion: Women with refractory PPH showed a different pattern of maternal characteristics and PPH causes compared with those with first-line treatment responsive PPH.

Popular models of finance, fall short of accounting for most empirically found stylized features of financial time series data, such as volatility clustering, skewness and leptokurtic nature of log returns. In this study, we propose a general framework for modeling asset returns which account for serial dependencies in higher moments and leptokurtic nature of scaled GARCH filtered residuals. Such residuals are calibrated to normal inverse Gaussian and hyperbolic distribution. Dynamics of risky assets assumed in Black Scholes model, Duans GARCH model and other benchmark models for contract valuation, are shown to be nested in the the proposed framework

INTRODUCTION
Human enterovirus (HEVs) infection is common, with an extensive array of clinical
displays ranging from asymptomatic to life-threatening. Presentation include nonspecific febrile
illness often accompanied by muscle pain, sore throat, abdominal discomfort, rash, headache,
encephalitis, aseptic meningitis and acute flaccid paralysis [2].
OBJECTIVES
The study objective was to investigate the natural selection and genetic variability of HEVs
and to identify HEV serotypes in circulation among children below 5 years old with diarrhea in
an informal settlement(Kibera) in Kenya.
METHODOLOGY
Specimens (n=628) from a prospective cohort study assessing the incidence and etiology of
diarrhea from 2009-2015 were analyzed. Enteric Taqman array cards (TAC) were used for initial
screening where two hundred and nine (78%) tested positive for HEVs.
Of these specimens, 72 (42%) had a cycle threshold (Ct) ≤30 and were tested by conventional
PCR targeting the 3’ regions of the viral protein 1 (VP1) gene. A total of 48 (67%) underwent
sequencing; 11 (23%) of which yielded nucleotide sequences. Phylogenetic analyses clustered
the Kenyan serotypes to HEVs groups C, B and A. Evaluation of the VP1 amino acid sequences
revealed numerous amino acid substitutions in relation to reference strains, which were confirmed
to be due to natural selection by negative or positive selection.
CONCLUSION
The Heterogeneous nature of stool samples is known to influence disparities in viral nucleic
acid yields. TAC detected 209 of which 171 (82%) were confirmed positive for HEVs by realtime
reverse transcription polymerase chain reaction (RRT-PCR), targeting the 5’ NTR regions.
Therefore, the results may not be a representative of all circulating HEVs in the study area. Since
this was a retrospective study of previously collected samples, it is possible that some HEVs strains
may have failed to amplify.

A search for a distribution which adequately describes the dynamics of log returns has been a subject of study for many years. Empirical evidence has resulted in stylized facts of returns. Arguably, in this study, the three components of returns, mean equation part, the changing variance. part and the resulting residuals are determined and their corresponding parameters estimated within the proposed framework. Spectral density analysis is used to trace the seasonality component.

Abstract
How much to spend on an option contract is the main problem at the task of pricing options. This
become more complex when it comes to projecting the future possible price of the option. This is attainable if one
knows the probabilities of prices either increasing, decreasing or remaining the same. Every investor wishes to make
profit on whatever amount they put in the stock exchange and thus the need for a good formula that give a very good
approximations to the market prices. This paper aims at introducing the concept of pricing options by using
numerical methods. In particular, we focus on the pricing of a European put option which lead us to having
American put option curve using Trinomial lattice model. In Trinomial method, the concept of a random walk is
used in the simulation of the path followed by the underlying stock price. The explicit price of the European put
option is known. Therefore at the end of the paper, the numerical prices obtained by the Black Scholes equation will
be compared to the numerical prices obtained using Trinomial and Binomial methods

Abstract
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.

Abstract
The CH2Cl2/MeOH (1:1) extract of the aerial parts of Tephrosia subtriflora afforded a new flavanonol, named subtriflavanonol (1), along with the known flavanone spinoflavanone B, and the known flavanonols MS-II (2) and mundulinol. The structures were elucidated by the use of NMR spectroscopy and mass spectrometry. The absolute configuration of the flavanonols was determined based on quantum chemical ECD calculations. In the antiplasmodial assay, compound 2 showed the highest activity against chloroquine-sensitive Plasmodium falciparum reference clones (D6 and 3D7), artemisinin-sensitive isolate (F32-TEM) as well as field isolate (KSM 009) with IC50 values 1.4–4.6 μM without significant cytotoxicity against Vero and HEp2 cell lines (IC50 > 100 μM). The new compound (1) showed weak antiplasmodial activity, IC50 12.5–24.2 μM, but also showed selective anticancer activity against HEp2 cell line (CC50 16.9 μM).

Description
β-Sitosterol (β-Sit) is a dietary phytosterol with demonstrated anticancer activity against a panel of cancers, but its poor solubility in water limits its bioavailability and therapeutic efficacy. In this study, poly (lactide-co-glycolic acid)(PLGA) and block copolymers of poly (ethylene glycol)-block-poly (lactic acid)(PEG-PLA) were used to encapsulate β-Sit into nanoparticles with the aim of enhancing its in vitro anticancer activity. β-Sitosterol-loaded PLGA and PEG-PLA nanoparticles (β-Sit-PLGA and β-Sit-PEG-PLA) were prepared by using a simple emulsion-solvent evaporation technique. The nanoparticles were characterized for size, particle size distribution, surface charge, and encapsulation efficiency. Their cellular uptake and antiproliferative activity was evaluated against MCF-7 and MDA-MB-231 human breast cancer cells using flow cytometry and MTT assays, respectively. β-Sit-PLGA and β-Sit-PEG-PLA nanoparticles were spherical in shape with average particle sizes of 215.0±29.7 and 240.6±23.3 nm, a zeta potential of− 13.8±1.61 and− 23.5±0.27 mV, respectively, and with narrow size distribution. The encapsulation efficiency of β-Sit was 62.89±4.66 and 51.83±19.72% in PLGA and PEG-PLA nanoparticles, respectively. In vitro release in phosphate-buffered saline (PBS) and PBS/with 0.2% Tween 20 showed an initial burst release, followed by a sustained release for 408 h. β-Sit-PLGA nanoparticles were generally stable in a protein-rich medium, whereas β-Sit-PEG-PLA nanoparticles showed a tendency to aggregate. Flow cytometry analysis (FACS) indicated that β-Sit-PLGA nanoparticles were efficiently taken up by the cells in contrast to β …

Forecasting future volumes of customer calls in call centers has proved to be a tedious and challenging task. This study, using time series analysis proposes two adequate ARIMA (p, d, q) models that are suitable to forecast two volumes of customer calls, IVR Hits Volumes and Offered Call volumes. 1472 times series data points from date 01/01/2014 to 11/01/2018 were obtained from a call center based in Kenya on the two variables of interest (IVR Hits Volumes and Offered Call volumes). The appropriate orders of the two models are picked based on the examination of the results of the ACF and PACF plots. The AIC criterion is used to select the best model for the data. The best ARIMA model for log IVR Hits volumes is ARIMA (5, 1, 3) with and the best ARIMA model for log Offered Call Volumes is ARIMA (6, 1, 3) with. The two models are recommended to model and forecast the daily arrival volumes of customer call data. The obtained forecast will be used in providing insights for appropriate workforce management

Mathematics is a very crucial subject in the school curriculum especially being a compulsory subject since the adoption of 8-4-4 system in Kenya. Mathematics is rated a very important subject because it makes a man methodical or systematic which depends on teacher’s qualification. The study sought to identify the effect of teacher qualification on students’ performance in Mathematics in the Uasin Gishu County. The study used descriptive survey design. The target population for this study consists of teachers of mathematics of two hundred and sixteen secondary schools in Uasin Gishu County. A sample of forty two secondary schools was purposively selected from the two hundred and sixteen schools. Simple random sampling technique was used to select 126 teachers. Primary data collected using questionnaires. Data collected was analyzed using inferential statistics using the Statistical Package for Social Sciences (SPSS). There was a positive significant relationship between teacher’s qualification and mathematics performance. From the linear regression model, (R2 = .092) showing that teachers qualification account for 9.2% variation in mathematics performance. The teacher’s qualification positively influenced the mathematics performance in secondary school. The Ministry of Education should offer an opportunity for further teacher professional training through workshops, seminars and short courses.

Kimanzi E, Ikua, MBUYA TO. "Key Performance Indicators for Manufacturing Safety in Paint Manufacturing: A Case of the Kenyan Industry." International Journal of Engineering Research and Technology. 2018;7(3):43-47 . Abstracthttp://dx.doi.org/10.17577/IJERTV7IS030043

Manufacturing safety is a key priority in the success of any business, as it can affect both the present and future competitive position of an organization. Organizations must measure safety in order to find areas of weakness, and then implement actions aimed at raising safety levels. Industrial accidents in the chemical industry indicate a need for both leading and lagging indicators of safety in the workplace.

The purpose of this study was to formulate and validate a set of key performance indicators that can be used in the measurement and reporting of manufacturing safety, and ensure a safe working environment for the workers on a continuous basis. The final results consisted of 21 Key Performance Indicators (KPIs), with fire safety being the most relevant KPI. The information gathered during a manufacturing safety performance measurement exercise can be used to implement activities directed towards reducing the level of worker exposure to health and safety risks within the factory, and thereby recommend application of these KPIs in managing of manufacturing safety in paint manufacturing and allied products industries.

Anopheles gambiae s.l. (Diptera: Culicidae) is responsible for the transmission of the devastating Plasmodium falciparum (Haemosporida: Plasmodiidae) strain of malaria in Africa. This study investigated the relationship between climate and environmental conditions and An. gambiae s.l. larvae abundance and modelled the larval distribution of this species in Baringo County, Kenya. Mosquito larvae were collected using a 350-mL dipper and a pipette once per month from December 2015 to December 2016. A random forest algorithm was used to generate vegetation cover classes. A negative binomial regression was used to model the association between remotely sensed climate (rainfall and temperature) and environmental (vegetation cover, vegetation health, topographic wetness and slope) factors and An. gambiae s.l. for December 2015. Anopheles gambiae s.l. was significantly more frequent in the riverine zone (P < 0.05, r = 0.59) compared with the lowland zone. Rainfall (b = 6.22, P < 0.001), slope (b = - 4.81, P = 0.012) and vegetation health (b = - 5.60, P = 0.038) significantly influenced the distribution of An. gambiae s.l. larvae. High An. gambiae s.l. abundance was associated with cropland and wetland environments. Effective malaria control will require zone-specific interventions such as a focused dry season vector control strategy in the riverine zone.
