Potential health-care associated respiratory syncytial virus in three referral Hospitals in Kenya, 2009-2011

Background: Respiratory syncytial virus (RSV) is a major cause of community acquired severe respiratory illness in infants, immunocompromised individuals and the elderly. Limited information exists on the contribution of RSV in respiratory Hospital Associated Infection (rHAI) in developing countries.Objective: To characterize Respiratory Syncytial Virus in the three Kenyan referral setting as a potential contributor to respiratory hospital acquired infection.Methods: The study targeted all patients whose samples tested positive for RSV from the ongoing surveillance on healthcare associated respiratory infections. The study collected nasal and oropharyngeal samples from patients who developed new-onset axilla fever and influenza like illness, in patients who had been afebrile for at least three (3) days in the wards and tested them for different respiratory pathogens (Influenza A and B, Parainfluenza, Human metapneumovirus and adenovirus) alongside RSV. During this period A total of 37 samples tested RSV positive. These were characterized as RSV-A and -B using RT-PCR. Those that typed successfully were then sequenced in the attachment G protein and phylogenetically analyzed.Results: Of the 37 samples, 13(35%) were RSV A, 6 (16%) RSV B, 1 (3%) was AB and 17 (46%) did not type. Twenty out of the 37 attained the sequencing criteria and only seventeen gave successful sequences. Three RSV- A and 2 RSV-B sequenced samples from KNH were 100% identical in the G ectodomain sequences. One RSV-A specimen from MDH and one RSV-A positive from NNPGH had 100% identity. Three sequences from KNH clustered with high nucleotide sequence identity. Children below 2years were significantly more at risk of RSV than those aged 5years and above (aOR=0.21,p=0.012).Conclusions: The study inferred possibility of spread of RSV within the hospitals especially the paediatric ward. Any interventions to curb the spread should specifically target all children ≤ 2 years.Afr J Health Sci. 2016; 29(1):1-1

Determination of vectorial potential of Mansonia species in the transmission of Wuchereria bancrofti in Tana-Delta District, Coast-Kenya

Background: Wuchereria bancrofti are parasites causing bancroftian filariasis which is transmitted by different species of mosquitoes. Mosquitoes of Anopheles, Culex and Aedes species are known to transmit W. bancrofti parasites.Objective: To determining the potential of Mansonia species; Ma. africanus and Ma. uniformis in the transmission of W. bancrofti.Design: Cross sectional study.Setting: Villages in Tana Delta district, Kenya.Subjects: In-door collected mosquitoes.Results: A total of one thousand, six hundred and sixty two (1632) female mosquitoes were collected by gravid traps, CDC light traps and Pyrethrum spray methods. Of these, 236 representing 14.5% were identified as Mansonia species. Two filarial larvae of stage two (L2) were obtained from the dissected mosquitoes. Polymerase chain reaction assays did not show any amplified W. bancrofti DNA from the obtained larvae or the mosquitoes.Conclusion: There was no evidence that Mansonia species play a role in the transmission of W. bancrofti

Formulation and evaluation of ibuprofen gel using a natural polymer

Prolonged oral use of ibuprofen for chronic conditions such as arthritis may cause peptic ulcer disease. Topical gel formulations have been developed to overcome this shortcoming. An immediate release formulation of ibuprofen would find application as a transdermal patch for management of chronic inflammatory conditions. In our study, a topical ibuprofen gel was found to have a better release profile for the active pharmaceutical ingredient than the marketed brand.Keywords: Ibuprofen, gel, immediate release, peptic ulcer diseas

Spatial distribution and co-infection with urogenital and intestinal schistosomiasis among primary school children in Migori County, Kenya

Background: Schistosomiasis is the most prevalent helminthic infection in sub-Saharan Africa. School age children have the highest burden. Chronic schistosome infections in children can have irreversible effects lasting throughout adulthood.Objective: To determine the prevalence, intensity and distribution of urogenital and intestinal schistosomiasis among primary school children in Migori County, Kenya.Design: Descriptive cross-sectional study.Setting: Primary schools in Migori County, Kenya.Subjects: Children aged seven to fourteen years.Results: We enrolled 1,784 children with the ratio of female to males being 1:1. Their mean age was 11.4 years (standard deviation ± 1.6). The overall prevalence of infection was 26%, with urogenital and intestinal schistosomiasis being found in 9% and 20% of children, respectively. A trend of increasing prevalence with increasing age of children was observed. Boys had a 50% higher risk of being infected with schistosomiasis when compared to girls (adjusted odds ratio 1.5, 95% confidence interval 1.2-1.9). Intensities of schistosome infections did not vary significantly across gender and age. Nyatike Constituency had the highest prevalence of schistosomiasis (54%).Prevalence in schools ranged from 1.7 to 89%. Seven schools (23%) had a schistosomiasis prevalence of at least 50% while 12 (39%) schools had schistosomiasis prevalence of between 10 and 50%.Conclusion: Our study showed that schistosomiasis is endemic in the study area and represents a significant public health problem among school children. The area should be prioritised for interventions including mass deworming, public health education and sanitation improvement

Prevalence and factors associated with unmet need for menstrual hygiene management in six countries in Sub-Saharan Africa: a multilevel analysis

Background Menstruation is a normal biological process experienced by more than 300 million women globally every day. Women require clean menstrual absorbents that can be changed as often as needed in a private and safe place with proper hygiene and disposal facilities. These needs must be met consistently throughout the duration of the menstrual cycle. Access to menstrual needs is crucial for women’s health, wellbeing, and dignity. This study assessed the prevalence and factors associated with unmet need for menstrual hygiene management (MHM) in Ethiopia, Kenya, Uganda, Burkina Faso, Ghana, and Niger. Methods We used data from the Performance Monitoring for Action (PMA) 2020 surveys. We defined the unmet need for MHM as the “lackof resources, facilities and supplies for MHM.” Sample characteristics were summarised using frequencies and percentages, while prevalence was summarised using proportions and their respective confidence intervals (CI). Factors associated with unmet need for MHM were assessed using multilevel logistic regression models. Results The study included 18,048 women of reproductive age from the six countries. The prevalence of unmet need for MHM was highest in Burkina Faso (74.8%), followed by Ethiopia (69.9%), Uganda (65.2%), Niger (57.8%), Kenya (53.5%), and lowest in Ghana (34.2%). Unmet need for MHM was consistently higher among uneducated and multiparous women, those who reused MHM materials, practiced open defecation, and lived in rural areas across all six countries. The odds of unmet need for MHM were higher among younger women under 35 years, unmarried women, those with lower education levels, and those from poorer households. Similarly, the reuse of MHM materials, use of shared or non-improved toilet facilities, and open defecation increased the odds of unmet need for MHM. In contrast, the presence of handwashing facilities reduced the odds of unmet need for MHM. Conclusion More than half of the women in five of the six countries have an unmet need for MHM, with significantly higher odds among younger women, those with low wealth status, the unmarried, and those with inadequate access to sanitary facilities. This study highlights the state of period poverty in Sub-Saharan Africa. Efforts to end period poverty should consider MHM needs as an integrated whole, as addressing each need in isolation is insufficient

Info Note: Strengthening Food Systems Transformation in East and Southern Africa: Leveraging Science Driven Business Acceleration to Catalyse Private Sector Finance

• Agriculture in Africa has untapped potential to meet regional and global food demands, but it faces challenges like fragmentation, inefficient value chains, and climate shocks. Transforming food systems will come at a cost. • There is an opportunity to harness business acceleration as a catalyst for private sector financing food systems transformation, and a powerful scaling mechanism for climate-smart agriculture (CSA). • Science and research have a role to play in business acceleration to support the adoption and strengthening of CSA practices, benefiting both agribusiness performance and smallholder farmers. • Combining tailored CSA technical assistance with investment readiness in an integrated approach holds significant potential for driving regional food systems transformation because it ensures that agribusinesses not only have access to the necessary knowledge and expertise but are also well-prepared to secure the financial resources required for implementing sustainable and climate-smart solutions. • Selecting appropriate funding partners and mechanisms, acquiring investment knowledge, nurturing relationships with capital providers, and showcasing social and environmental impact are vital for successful financing in the agriculture sector

Understanding the potential impact of different drug properties on SARS-CoV-2 transmission and disease burden : a modelling analysis

Q1Q1Background The unprecedented public health impact of the COVID-19 pandemic has motivated a rapid search for potential therapeutics, with some key successes. However, the potential impact of different treatments, and consequently research and procurement priorities, have not been clear. Methods and Findings develop a mathematical model of SARS-CoV-2 transmission, COVID-19 disease and clinical care to explore the potential public-health impact of a range of different potential therapeutics, under a range of different scenarios varying: i) healthcare capacity, ii) epidemic trajectories; and iii) drug efficacy in the absence of supportive care. In each case, the outcome of interest was the number of COVID-19 deaths averted in scenarios with the therapeutic compared to scenarios without. We find the impact of drugs like dexamethasone (which are delivered to the most critically-ill in hospital and whose therapeutic benefit is expected to depend on the availability of supportive care such as oxygen and mechanical ventilation) is likely to be limited in settings where healthcare capacity is lowest or where uncontrolled epidemics result in hospitals being overwhelmed. As such, it may avert 22% of deaths in highincome countries but only 8% in low-income countries (assuming R=1.35). Therapeutics for different patient populations (those not in hospital, early in the course of infection) and types of benefit (reducing disease severity or infectiousness, preventing hospitalisation) could have much greater benefits, particularly in resource-poor settings facing large epidemics. Conclusions There is a global asymmetry in who is likely to benefit from advances in the treatment of COVID-19 to date, which have been focussed on hospitalised-patients and predicated on an assumption of adequate access to supportive care. Therapeutics that can feasibly be delivered to those earlier in the course of infection that reduce the need for healthcare or reduce infectiousness could have significant impact, and research into their efficacy and means of delivery should be a priorityRevista Internacional - Indexad

Research agenda for preventing mosquito-transmitted diseases through improving the built environment in sub-Saharan Africa

Mosquito-transmitted diseases are a major threat to health in sub-Saharan Africa, but could be reduced through modifications to the built environment. Here we report findings from a major workshop held to identify the research gaps in this area, namely: (1) evidence of the health benefits to changes to the built environment, (2) understanding how mosquitoes enter buildings, (3) novel methods for reducing mosquito-house entry, (4) sustainable approaches for reducing mosquito habitats, (5) case studies of micro-financing for healthy homes and (6) methods for increasing scale-up. Multidisciplinary research is essential to build out mosquito-transmitted diseases, and not build them in
