Are dormancy management and physiological age the achilles' heel of aeroponic minituber production in seed potato value chains in SSA?

Scarcity of good quality seed is major obstacle to expanded potato (Solanum tuberosum L.) production in sub-saharan Africa (SSA). Constraints in availability and supply of seed potato are partly attributable to challenges in production of pre-basic which is an intermediary step necessary in production of seed tubers in the seed potato value chain. Aeroponic minutuber production is a relatively recent technology that has the potential to break the seed potato bottleneck in many SSA countries due to several advantages that it holds especially those related to high multiplication rates; typically (1:50-100) that arise from sequential harvesting. There are, however, a number of potential challenges which, if not addressed, can contribute to non attainment of the projected increases in seed availability and not only mess up the 3 generation (3G) revolution strategy of boosting seed tuber production in SSA but also jeopardize the adoption of the technology. Besides problems associated with failure of electricity supply and management of nutrition, the Achilles‘ heel of aeroponic minituber production is probably the large variation in physiological age of resulting tubers due to sequential harvesting that takes place over several months during the production cycle. In the absence of cold storage facilities which are few and beyond the reach of many pre-basic seed potato growers in many SSA countries, harvested minitubers can either be at dormant, apical dominance, multiple sprouting or senile stage when they are required for planting with significant impacts on subsequent yields. This paper discusses the problems associated with physiological age in seed tuber systems based on aeroponic minitubers and proposes some approaches that may overcome these challenges to ensure that the promise of aeroponic minituber production is realized. The proposed approaches include the strategic application of dormancy inhibiting and dormancy promoting substances at various stages of aeroponic minituber production combined with the use of low cost storage systems such as the diffused light storage technology depending on the dormancy period of the variety (ies) being grown

Assessment of Patient Satisfaction with Nursing Care at a Large Public Referral Hospital in Kenya

Patient satisfaction with nursing care is known to predict patient outcomes. Nursing care offered by the largest single technical group in any hospital, is known to often determine the overall quality of care offered. This study hence examined the extent to which patients at a Referral hospital in Western Kenya are satisfied with the nursing care they receive. A cross sectional exit survey of discharged patients using a self-administered patient questionnaire was used. 274 patients participated, of which 65.6% were female. 94.1% had formal education with 59.1% reporting that this was their maiden visit to the hospital. Overall, 87% of patients felt satisfied with nursing care received. Most (81.8%) of the patients interviewed felt they had been promptly attended to, with a further 71.6% rating the nurses as competent and knowledgeable in their clinical care. The ward in which the patient had been admitted and the number of days a patient had spent in hospital were found to be significantly associated with reporting of overall satisfaction with nursing care (p=0.037 & 0.03 respectively). Since nursing care is determinant of patient outcomes during hospitalization, clinical care administrators should often emphasize on the Nurses’ technical competence and interpersonal relationships throughout patient care. Prompt quality nursing care should be prioritized to match with patient expectations in each hospital units and ensure patient satisfaction through reduction of length of stay in hospital. Key words: Assessment, patient satisfaction, nursing car

Psychosocial and mental health challenges faced by emerging adults living with HIV and support systems aiding their positive coping: a qualitative study from the Kenyan coast

Background: In sub-Saharan Africa, there is little data on the challenges faced by young people living with HIV tran- sitioning into adult life. Adapting the socio-ecological framework, this qualitative study investigated the challenges faced by emerging adults living with HIV from a rural Kenyan setting. Additionally, the study explored support systems that aid positive coping among these young adults. Methods: In April 2018, in-depth interviews were conducted with a convenience sample of 22 young adults living with HIV (12 females), 18–24 years old, from rural Kilifi, coast of Kenya. Data were analyzed thematically using NVIVO 11 software. Results: Young adults living with HIV from this setting face various challenges at different levels of the social eco- system. At the individual level, key challenges they reported included acceptance of HIV positive status, antiretroviral adherence, economic burden associated with access to healthcare, building an intimate relationship, mental health problems, and HIV status disclosure. At the family level, death of parents, poverty, and being unaccepted were the commonly mentioned challenges. At the community level, socialization difficulties and long waiting time at the HIV clinic were highlighted. HIV stigma and discrimination were frequently reported across the different levels. Economic independence, social support (from families, friends, organizations, healthcare providers and peer meetings), and reli- ance on spirituality aided positive coping among these young adults amidst the challenges of living with HIV. Conclusions: In this rural setting, emerging adults living with HIV face various challenges at the individual, family, and community level, some of which are cross-cutting. Our findings underscore the need for designing multi-level youth-friendly interventions that can address modifiable challenges encountered by emerging adults living with HIV in this and similar settings. Such interventions should incorporate appropriate context-specific support structures that may help these young people smoothly transit into adult life

HIV virological non-suppression is highly prevalent among 18- to 24-year-old youths on antiretroviral therapy at the Kenyan coast

Background: In sub-Saharan Africa, data on virologic outcomes of young people living with HIV (YLWH) enrolled on antiretroviral therapy (ART) remains scarce. In this study, we describe the prevalence of HIV virological non-suppression (VNS) and its associated factors among YLWH aged 18–24 years from the Kenyan coast. Methods: Data were analyzed for 384 YLWH who participated in a larger cross-sectional study conducted between November 2018 and September 2019 in two counties at the Kenyan coast (Kilif and Mombasa). Descriptive statistics were used to summarize sample characteristics and logistic regression was used for statistical modeling of factors associated with VNS. In this study, VNS was defned as plasma viral load≥1000 copies/mL. Results: Among these YLWH with a mean age of 20.7 years (SD=2.2); 55.5% females, the overall prevalence of VNS was 32.0% (95% Confdence interval (95% CI): 27.5, 36.9%). In the multivariable logistic regression analysis, being from a largely rural setting (adjusted Odds Ratio (aOR) 1.73, 95% CI 1.10, 2.71; p=0.02), underweight (aOR 1.87, 95% CI 1.16, 3.01; p=0.01) and low self-reported ART adherence (aOR 2.83, 95% CI 1.34, 6.00; p=0.01) were signifcantly associated with higher odds of VNS in YLWH. Conclusions: In this study, high levels of VNS were observed among YLWH and this was signifcantly associated with rural residency, nutritional and ART adherence problems. ART adherence counselling and nutritional support and education should be intensifed in this setting targeting YLWH residing mostly in rural areas. Given the high frequency of VNS, there is need to closely monitor viral load and profle HIV drug resistance patterns in youths from the Kenyan coast with confrmed virologic failure. The latter will help understand whether drug resistance also contributes to poor viral suppression in addition to, or exclusive of suboptimal ART adherenc

Malnutrition and cachexia among cancer out-patients in Nairobi, Kenya

Cancer is the third leading cause of death in Kenya. However, there is scarce information on the nutritional status of cancer patients to guide in decision making. The present study sought to assess the risk of malnutrition, and factors associated with malnutrition and cachexia, among cancer out-patients, with the aim of informing nutrition programmes for cancer management in Kenya and beyond. This was a facility-based cross-sectional study performed at Kenyatta National Hospital and Texas Cancer Centre in Nairobi, Kenya. The risk of malnutrition was assessed using the Malnutrition Universal Screening Tool (MUST). Diagnoses of malnutrition and cachexia were done using the European Society of Clinical Nutrition and Metabolism (ESPEN) and Fearon criteria, respectively. A total of 512 participants were assessed. Those at risk of malnutrition were 33·1 % (12·5 % at medium risk, 20·6 % at high risk). Prevalence of malnutrition was 13·4 %. The overall weight loss >5 % over 3 months was 18·2 % and low fat-free mass index was 43·1 %. Prevalence of cachexia was 14·1 % compared with 8·5 % obtained using the local criteria. Only 18·6 % participants had received any form of nutrition services. Age was a predictor of malnutrition and cachexia in addition to site of cancer for malnutrition and cigarette smoking for cachexia. The use of the MUST as a screening tool at the first point of care should be explored. The predictive value of current nutrition assessment tools, and the local diagnostic criteria for malnutrition and cachexia should be reassessed to inform the development of appropriate clinical guidelines and future capacity-building initiatives that will ensure the correct identification of patients at risk for timely care

Alcohol and illicit drug use among young people living with HIV compared to their uninfected peers from the Kenyan coast: prevalence and risk indicators

Background: In sub-Saharan Africa, there is paucity of research on substance use patterns among young people living with HIV (YLWH). To address the gap, we sought to: i) determine the prevalence of substance use, specifically alcohol and illicit drug use, among YLWH compared to their HIV-uninfected peers; ii) investigate the independent association between young people’s HIV infection status and substance use; iii) investigate the risk indicators for substance use among these young people. Methods: Between November 2018 and September 2019, a cross-sectional study was conducted at the Kenyan coast recruiting 819 young people aged 18–24 years (407 HIV-positive). Alcohol and drug use disorders identification tests (AUDIT and DUDIT) were administered via audio computer-assisted self-interview alongside other measures. Logistic regression was used to determine substance use risk indicators. Results: The point prevalence of current substance use was significantly lower among YLWH than HIV-uninfected youths: current alcohol use, 13% vs. 24%, p \u3c 0.01; current illicit drug use, 7% vs. 15%, p \u3c 0.01; current alcohol and illicit drug use comorbidity, 4 vs. 11%, p \u3c 0.01. Past-year prevalence estimates for hazardous substance use were generally low among young people in this setting (\u3c 10%) with no significant group differences observed. Being HIV-positive independently predicted lower odds of current substance use, but not hazardous substance use. There was overlap of some risk indicators for current substance use between young people with and without HIV including male sex, khat use and an experience of multiple negative life events, but risk indicators unique to either group were also identified. Among YLWH, none of the HIV-related factors was significantly associated with current substance use. Conclusions: At the Kenyan coast, substance use is a reality among young people. The frequency of use generally appears to be low among YLWH compared to the HIV-uninfected peers. Substance use prevention initiatives targeting young people, regardless of HIV infection status, are warranted in this setting to avert their potential risk for developing substance use disorders, including dependence. The multifaceted intrapersonal and interpersonal factors that place young people at risk of substance use need to be addressed as part of the substance use awareness and prevention initiatives

Molecular epidemiology of Klebsiella pneumoniae invasive infections over a decade at Kilifi County Hospital in Kenya.

Multidrug resistant (MDR) Klebsiella pneumoniae is a common cause of nosocomial infections worldwide. Recent years have seen an explosion of resistance to extended-spectrum ?-lactamases (ESBLs) and emergence of carbapenem resistance. Here, we examine 198 invasive K. pneumoniae isolates collected from over a decade in Kilifi County Hospital (KCH) in Kenya. We observe a significant increase in MDR K. pneumoniae isolates, particularly to third generation cephalosporins conferred by ESBLs. Using whole-genome sequences, we describe the population structure and the distribution of antimicrobial resistance genes within it. More than half of the isolates examined in this study were ESBL-positive, encoding CTX-M-15, SHV-2, SHV-12 and SHV-27, and 79% were MDR conferring resistance to at least three antimicrobial classes. Although no isolates in our dataset were found to be resistant to carbapenems we did find a plasmid with the genetic architecture of a known New Delhi metallo-?-lactamase-1 (NDM)-carrying plasmid in 25 isolates. In the absence of carbapenem use in KCH and because of the instability of the NDM-1 gene in the plasmid, the NDM-1 gene has been lost in these isolates. Our data suggests that isolates that encode NDM-1 could be present in the population; should carbapenems be introduced as treatment in public hospitals in Kenya, resistance is likely to ensue rapidly

Prevalence and determinants of human papillomavirus infection and cervical lesions in HIV-positive women in Kenya

Background: We assessed the association of human papillomavirus (HPV) infection and cervical intraepithelial neoplasia (CIN) with various characteristics, CD4 count and use of combination antiretroviral therapy (cART) among HIV-positive women. Methods: Cross-sectional study of 498 HIV-positive women who underwent HPV PCR-based testing, cytology, and systematic cervical biopsy. Results: In all, 68.7% of women were HPV-positive, 52.6% had high-risk (hr) HPV, and 40.2% multiple type infections. High-risk human papillomavirus-positivity did not vary significantly by age but it was negatively associated with education level. The most frequent types in 113 CIN2/3 were HPV16 (26.5%), HPV35 (19.5%), and HPV58 (12.4%). CD4 count was negatively associated with prevalence of hrHPV (Po0.001) and CIN2/3 among non-users of cART (P¼0.013). Combination antiretroviral therapies users (X2 year) had lower hrHPV prevalence (prevalence ratio (PR) vs non-users¼0.77, 95% confidence interval (CI): 0.61–0.96) and multiple infections (PR¼0.68, 95% CI: 0.53–0.88), but not fewer CIN2/3. The positive predictive value of hrHPV-positivity for CIN2/3 increased from 28.9% at age o35 years to 53.3% in X45 years. Conclusion: The burden of hrHPV and CIN2/3 was high and it was related to immunosuppression level. Combination antiretroviral therapies (X2 year) use had a favourable effect on hrHPV prevalence but cART in our population may have been started too late to prevent CIN2/3
