The Role of Leather Microbes in Human Health

Leather tanned from raw hides and skins have been used to cover and protect the human body since early man. The skin of an animal carries thousands of microbes. Some are beneficial and protect the animal while others are pathogenic and cause diseases. Some microbes have no defined roles in animals. These microbes end up in the human body through contact with the animal skin. In recent years, the human body has been studied as an ecosystem where trillions of microorganisms live as a community called microbiome. Humans need beneficial microbes like Bacillus subtilis on the skin surface to stay healthy. Many microbes need the human body to survive. Not many studies have looked into the close link between animal leather and the human microbiome. The assumption is that conventional leather processes inhibit the pathogens on skins from carrying any risk of microbial hazard to the human body. This chapter identifies endemic microbes of “animal skin microbiome” that withstand extreme acidity and alkalinity of leather manufacture and their transmission to humans. Some cause allergic reactions, skin lesion, infections or death to tannery employees with weakened immune systems. This promotes the need to look at leather product microbiome impact on human health

Men and infertility in The Gambia : limited biomedical knowledge and awareness discourage male involvement and exacerbate gender-based impacts of infertility

Introduction Infertility in Sub-Saharan Africa constitutes an important social and public health problem. Yet, there is a paucity of research on the experiences of men living with infertility, especially in West Africa. This study explored men’s aetiological knowledge, views and experiences of infertility in the West Coast region of The Gambia, West Africa. Methodology An explorative qualitative study was conducted among men living in the rural and urban communities of the West Coast region of The Gambia using in-depth interviews. Data collection and analysis were performed concurrently, and thematic data analysis was an iterative process carried out using NVivo 11 Analysis Software. Results Gambian men had generally poor knowledge of infertility, allocating it to God, spiritual powers and bodily (biomedical) factors. While societal norms meant that infertility was generally attributed to women, some men allocated male-factor infertility to poor sperm quality and impotence. Infertility threatened participants’ sense of masculinity and resulted in psychosocial distress, including stigma, feelings of isolation, and low self-esteem. Conclusion Normative gendered frameworks of infertility result in high levels of female responsibilisation in the Gambian context. Yet men diagnosed with infertility experience significant, often unrecognized, psychological and social distress. We therefore call for increased attention to male-factor infertility, and the promotion of male engagement with infertility-care and services, both of which are essential for successfully addressing infertility and it’s psychosocial consequences in The Gambia

Socio-anthropological methods to study the feasibility and acceptability of the minimally invasive autopsy from the perspective of local communities: lessons learnt from a large multi-centre study

The minimally invasive autopsy (MIA), an innovative approach for obtaining post-mortem samples of key organs, is increasingly being recognized as a robust methodology for cause of death (CoD) investigation, albeit so far limited to pilot studies and research projects. A better understanding of the real causes of death in middle- and low-income countries, where underlying causes of death are seldom determined, would allow improved health planning, more targeted prioritization of available resources and the implementation of coherent public health policies. This paper discusses lessons learnt from the implementation of a Feasibility and Acceptability (F&A) study evaluating the MIA approach in five countries: Gabon, Kenya, Mali, Mozambique and Pakistan. This article reports the methodological choices made to document sociocultural and religious norms around death, to examine community and relatives’ attitudes and perceptions towards MIA, and to identify factors motivating the MIA’s acceptance and refusal. We used ethnography, grounded theory and framework method approaches. In-depth and semi-structured interviews and focus group discussions with key informants, including next of kin of deceased individuals and healthcare providers, were conducted. Participant observation and direct observation of procedures and ceremonies around death were organized in all study sites. In Mozambique, MIA procedures were observed and case studies conducted. The implementation of this F&A protocol has provided critical lessons that could facilitate the future implementation of post-mortem procedures for CoD investigation. These include the need for early community engagement, staff training and preparedness, flexibility to adapt the protocol, gathering qualitative data from diverse sources, and triangulation of the data. We have applied a rigorous, effective and culturally sensitive methodological approach to assess the F&A of MIA in resource-constrained settings. We strongly recommend that such an approach is applied in settings where MIAs or similar post-mortem sensitive procedures are to be introduce

Prevalence of reproductive tract infections and the predictive value of girls’ symptom-based reporting: findings from a cross-sectional survey in rural western Kenya

Objectives Reproductive tract infections (RTIs), including sexually acquired, among adolescent girls is a public health concern, but few studies have measured prevalence in low-middle-income countries. The objective of this study was to examine prevalence in rural schoolgirls in Kenya against their reported symptoms. Methods In 2013, a survey was conducted in 542 adolescent schoolgirls aged 14–17 years who were enrolled in a menstrual feasibility study. Vaginal self-swabbing was conducted after girls were interviewed face-to-face by trained nurses on symptoms. The prevalence of girls with symptoms and laboratory-confirmed infections, and the sensitivity, specificity, positive and negative predictive values of symptoms compared with laboratory results, were calculated. Results Of 515 girls agreeing to self-swab, 510 answered symptom questions. A quarter (24%) reported one or more symptoms; most commonly vaginal discharge (11%), pain (9%) or itching (4%). Laboratory tests confirmed 28% of girls had one or more RTI. Prevalence rose with age; among girls aged 16–17 years, 33% had infections. Bacterial vaginosis was the most common (18%), followed by Candida albicans (9%), Chlamydia trachomatis (3%), Trichomonas vaginalis (3%) and Neisseria gonorrhoeae (1%). Reported symptoms had a low sensitivity and positive predictive value. Three-quarters of girls with bacterial vaginosis and C. albicans, and 50% with T. vaginalis were asymptomatic. Conclusions There is a high prevalence of adolescent schoolgirls with RTI in rural Kenya. Public efforts are required to identify and treat infections among girls to reduce longer-term sequelae but poor reliability of symptom reporting minimises utility of symptom-based diagnosis in this population.

Examining the safety of menstrual cups among rural primary school girls in western Kenya: observational studies nested in a randomised controlled feasibility study.

Examine the safety of menstrual cups against sanitary pads and usual practice in Kenyan schoolgirls. Observational studies nested in a cluster randomised controlled feasibility study. 30 primary schools in a health and demographic surveillance system in rural western Kenya. Menstruating primary schoolgirls aged 14-16 years participating in a menstrual feasibility study. Insertable menstrual cup, monthly sanitary pads or 'usual practice' (controls). Staphylococcus aureus vaginal colonization, Escherichia coli growth on sampled used cups, toxic shock syndrome or other adverse health outcomes. Among 604 eligible girls tested, no adverse event or TSS was detected over a median 10.9 months follow-up. S. aureusprevalence was 10.8%, with no significant difference over intervention time or between groups. Of 65 S.aureus positives at first test, 49 girls were retested and 10 (20.4%) remained positive. Of these, two (20%) sample isolates tested positive for toxic shock syndrome toxin-1; both girls were provided pads and were clinically healthy. Seven per cent of cups required replacements for loss, damage, dropping in a latrine or a poor fit. Of 30 used cups processed for E. coli growth, 13 (37.1%, 95% CI 21.1% to 53.1%) had growth. E. coli growth was greatest in newer compared with established users (53%vs22.2%, p=0.12). Among this feasibility sample, no evidence emerged to indicate menstrual cups are hazardous or cause health harms among rural Kenyan schoolgirls, but large-scale trials and post-marketing surveillance should continue to evaluate cup safety

Building menstrual health and hygiene-supportive environments: exploring teachers’ experience in rural Western Kenya

Introduction: Existing school environments and staff play a critical role in Menstrual Health and Hygiene (MHH) for school aged girls in middle and low-income countries. This paper leverages teachers’ perspectives on menstruation and the impact of the Menstrual Solutions (MS) study, an open cluster randomized controlled feasibility study to determine the impact of puberty education, nurses support, and menstrual product provision on girls’ academic performance and emotional well-being. Methods: Seventeen focus group discussions were conducted from October 2012 through November 2013 with teachers at six participating schools, held at three different time points during the study period. Results: Key themes that emerged were emotions and blood, absenteeism, the role of teachers in MHH, and the impact of sensitization. Teachers noted that poor MHH had an impact on school attendance, transparency and openness with teachers, and student behavior in class. It was reported that adolescent girls would absent themselves for 3–5 days during their menstrual cycle depending on what materials they could use, and they would often shy away from teachers, when possible, only speaking to them about their menses if it was urgent or they needed to go home. Emotions such as fear and embarrassment were commonly associated with bleeding. At the midpoint and end of the study, teachers noted that the puberty education and menstrual product provision (where applicable) had a positive impact on girls’ attendance, attention, and comfort in the classroom. Girls became more open with both male and female teachers about their menses, and more comfortable and confident in the classroom among all classmates. Discussion: This research highlights the importance of building an MHH-supportive environment with multiple school personnel within schools to develop a gender-equitable environment for girls to learn confidently without undue interference. Teachers are key adults in adolescent girls’ lives, having the potential to foster an environment that empowers girls with greater autonomy to manage their menses. This highlights a need to consider their perspectives in intervention development. Sensitization of teachers and puberty education across both genders are key components to developing the MHH-supportive environment in schools

Plant Breeding in Sub?Saharan Africa in an Era of Donor Dependence

Since the Asian Green Revolution, plant breeding has been seen as a core capacity in most agricultural research institutes around the world, including those in Africa. Outside some private sector breeding for hybrid maize in East and Southern Africa, plant breeding is essentially a public sector activity and over the last four decades has relied significantly on international development assistance, and so has been susceptible to shifts in donor funding for agricultural research. The performance of programmes has been affected by these trends, with the balance between the scale economies in plant breeding and the local adaptation needed to satisfy farmer demand influenced by a complex and sometimes problematic division of labour between the international agricultural research centres (IARCs) of the Consultative Group on International Agricultural Research (CGIAR) and the breeding programmes of National Agricultural Research Institutes (NARIs)

Costing analysis of an SMS-based intervention to promote HIV self-testing amongst truckers and sex workers in Kenya

Objective HIV testing rates in many sub-Saharan African countries have remained suboptimal, and there is an urgent need to explore strategic yet cost-effective approaches to increase the uptake of HIV testing, especially among high-risk populations. Methods A costing analysis was conducted for a randomized controlled trial (RCT) with male truckers and female sex workers (FSWs) registered in the electronic health record system (EHRS) of the North Star Alliance, which offers healthcare services at major transit hubs in Southern and East Africa. The RCT selected a sample of truckers and FSWs who were irregular HIV testers, according to the EHRS, and evaluated the effect of SMSs promoting the availability of HIV self-testing (HIVST) kits in Kenyan clinics (intervention program) versus a general SMS reminding clients to test for HIV (enhanced and standard program) on HIV testing rates. In this paper, we calculated costs from a provider perspective using a mixed-methods approach to identify, measure, and value the resources utilized within the intervention and standard programs. The results of the analysis reflect the cost per client tested. Results The cost of offering HIVST was calculated to be double that of routine facility-based testing (USD 10.13 versus USD 5.01 per client tested), primarily due to the high price of the self-test kit. In the two study arms that only offered provider-administered HIV testing in the clinic, only 1% of truckers and 6% of FSWs tested during the study period, while in the intervention arm, which also offered HST, approximately 4% of truckers and 11% of FSWs tested. These lower than expected outcomes resulted in relatively high cost per client estimates for all three study arms. Within the intervention arm, 65% of truckers and 72% of FSWs who tested chose the HIVST option. However, within the intervention arm, the cost per additional client tested was lower for FSWs than for truckers, at USD 0.15 per additional client tested versus USD 0.58 per additional client tested, driven primarily by the higher response rates. Conclusion Whilst the availability of HIVST increased HIV testing among both truckers and FSWs, the cost of providing HIVST is higher than that of a routine health facility-based test, driven primarily by the price of the HIV self-test kit. Future research needs to identify strategies which increase demand for HIVST, and determine whether these strategies and the subsequent increased demand for HIVST are cost-effective in relation to the conventional facility based testing currently available

Conceptual frameworks for understanding the acceptability and feasibility of the minimally invasive autopsy to determine cause of death: Findings from the CADMIA Study in western Kenya

Establishing the cause of death (CoD) is critical to better understanding health and prioritizing health investments, however the use of full post-mortem examination is rare in most low and middle-income counties for multiple reasons. The use of minimally invasive autopsy (MIA) approaches, such as needle biopsies, presents an alternate means to assess CoD. In order to understand the feasibility and acceptability of MIA among communities in western Kenya, we conducted focus groups and in-depth interviews with next-of-kin of recently deceased persons, community leaders and health care workers in Siaya and Kisumu counties. Results suggest two conceptual framework can be drawn, one with facilitating factors for acceptance of MIA due to the ability to satisfy immediate needs related to interest in learning CoD or protecting social status and honoring the deceased), and one framework covering barriers to acceptance of MIA, for reasons relating to the failure to serve an existing need, and/or the exacerbation of an already difficult time
