Chemical and thermal properties of VIP latrine sludge

This study investigated the chemical and thermal properties of faecal sludge from 10 dry VIP latrines in Bester’s Camp in the eThekwini Municipality, Durban, South Africa. Faecal sludge samples were selected at different depths and from the front and back sections of 10 VIP latrines during a manual emptying process. The samples were analysed for: moisture content; volatile solids; chemical oxygen demand; ammonia; total Kjeldahl nitrogen; pH; orthophosphate; thermal conductivity; calorific value and heat capacity. These properties will facilitate the design of faecal sludge emptying and treatment equipment. A manual sorting of the pit contents was carried out to determine the categories and amounts of household waste present. There was a significant difference in the moisture, volatile solids, chemical oxygen demand, ammonia, total Kjeldahl nitrogen and orthophosphate content of the faecal sludge between the front and back sections of the pit. There was minimal change in the thermal properties within the pit. The median values through the pit of each property analysed were: moisture content – 0.81 g water/g wet mass; volatile solids – 1.5 g VS/g ash; COD – 1.7 g COD/g ash; ammonia nitrogen – 10 mg NH3-N/g dry mass; TKN – 39 mg N/g dry mass; pH – 8.03; orthophosphate – 0.06 mg PO4/g dry mass; thermal conductivity – 0.55 W/m K; calorific value – 14 kJ/g dry mass; heat capacity – 2.4x103 kJ/kg K. On average, 87% of pit content is faecal sludge; the remainder consists of wastes such as paper, plastics and textiles.Keywords: faecal sludge, VIP latrines, chemical properties, thermal propertie

Family Planning Among Hiv Positive And Negative Clients In A Resource Poor Setting In South Africa

Objective: To investigate family planning needs, knowledge of HIV transmission and HIV disclosure in a cohort sample that had undergone PMTCT in a resource poor setting. Design. Cross-sectional survey. Setting: Five clinics implementing PMTCT from Qaukeni Local Service Area, O.R. Tambo District in the Eastern Cape. Subjects: The sample at postnatal care consisted of one postnatal interview (n= 1310) when the infants were aged three months or less (n= 141, 10.8%), 4-6 months (n=200, 15.3%), 7-12 months (n=785, 59.9%), or 13-18 months (n=183, 14.0%). Results: One hundred and sixteen women were found HIV positive, 642 HIV negative and 552 with unknown HlV status. Considering those with HIV test results, 15.3% were HIV positive. Almost four out of five women got counselling on safe sex during pregnancy but only two out of three women practiced safe sex during pregnancy. Postnatally, almost all women received counselling on family planning, yet use of contraceptives and condoms were low. HIV positive women used condoms more often than HIV negative women. HIV positive women were significantly more likely than HIV negative women to say that they did not intend to have more children. For HIV positive women PMTCT knowledge was a positive predictor for the intention to have a child, while age, having a partner, HIV disclosure to partner and number of children were not significant. Pregnancy desire did not differ between HIV positive and HIV negative women regarding marital status, having two or more live births and HIV disclosure. Conclusion: High pregnancy desires, low contraceptive and condom use were found among HIV positive women. The incorporation of HIV prevention into promotion of contraceptives by family planning programmes and service providers needs to be improved. East African Medical Journal Vol. 85 (3) 2008: pp. 20-2

HIV risk perception and behavior among medically and traditionally circumcised males in South Africa

Abstract Background In South Africa, voluntary medical male circumcision (VMMC) has recently been implemented as a strategy for reducing the risk of heterosexual HIV acquisition among men. However, there is some concern that VMMC may lead to low risk perception and more risky sexual behavior. This study investigated HIV risk perception and risk behaviors among men who have undergone either VMMC or traditional male circumcision (TMC) compared to those that had not been circumcised. Methods Data collected from the 2012 South African national population-based household survey for males aged 15 years and older were analyzed using bivariate and multivariate multinomial logistic regression, and relative risk ratios (RRRs) with 95 % confidence interval (CI) were used to assess factors associated with each type of circumcision relative no circumcision. Results Of the 11,086 males that indicated that they were circumcised or not, 19.5 % (95 % CI: 17.9–21.4) were medically circumcised, 27.2 % (95 % CI: 24.7–29.8) were traditionally circumcised and 53.3 % (95 % CI: 50.9–55.6) were not circumcised. In the final multivariate models, relative to uncircumcised males, males who reported VMMC were significantly more likely to have had more than two sexual partners (RRR = 1.67, p = 0.009), and males who reported TMC were significantly less likely to be low risk alcohol users (RRR = 0.72, p < 0.001). Conclusion There is a need to strengthen and improve the quality of the counselling component of VMMC with the focus on education about the real and present risk for HIV infection associated with multiple sexual partners and alcohol abuse following circumcision

Factors impacting the selection of psychiatric hospitals for community service placement of nurses

Background. As a strategy to promote access to quality health services, including psychiatric nursing, compulsory community service for nurses wasintroduced in January 2008.Objective. To determine the factors impacting the KwaZulu-Natal College of Nursing (KZNCN) student nurses’ selection of psychiatric hospitals as theirplacement areas for community service.Methods. A quantitative, exploratory, descriptive research design was adopted. Convenience sampling was used to select 125 respondents from sixcampuses of KZNCN. An electronic 5-point Likert scale-based self-administered questionnaire was used to collect data. SPSS version 26 (IBM Corp.,USA) was used for data analysis.Results. The study found that the following factors impacted the selection of psychiatric hospitals for community service: insufficient time allocated forthe practice of psychiatry during training; fear of exposure to threat; poor infrastructure and scarce facilities; and insufficient danger allowance.Conclusion. A positive practice environment should be created in psychiatric hospitals to attract student nurses and retain them in the psychiatricenvironment after community service

The clinical profile and outcome of children with West syndrome in KwaZulu-Natal Province, South Africa: A 10-year retrospective review

Background. West syndrome (WS) is a rare epileptic encephalopathy of infancy. There is currently no research on the incidence or prevalence of WS in Africa. Methods. We aimed to describe the outcome of children with WS at a quaternary-level hospital in KwaZulu-Natal, South Africa (SA). This was a retrospective chart review conducted on patients diagnosed with WS over a 10-year period. Eight children (males, n=7; African, n=6; Asian, n=2) identified with WS out of 2 206 admitted with epilepsy. The median age (range) at diagnosis was 7.5 (1 - 9) months. The average time between onset of epileptic spasms and diagnosis was 3.1 months. Results. Six patients had abnormal neuroimaging (atrophy (n=2); corpus callosum agenesis (n=2); tuberous sclerosis (n=1); focal dysplasia (n=1)). Drug management included sodium valproate (n=8), topiramate (n=7) and levetiracetam (n=3). Subsequent definitive treatment was intramuscular adrenocorticotrophic hormone (n=3), vigabatrin (n=2) and oral prednisone (n=4). Four (50%) patients had complete seizure remission (neuromigratory disorder (n=2); tuberous sclerosis (n=1); and idiopathic (n=1)) and 4 had partial remission (neonatal complications (n=3); idiopathic (n=1)). Discussion. Most of our patients had symptomatic WS, with 50% remission on treatment. Outcomes were poorer in our study when compared with those in published data. Conclusion. Further collaborative studies are still needed to evaluate the true impact and prevalence of WS in SA

Young people's experiences of sexual and reproductive health interventions in rural KwaZulu-Natal, South Africa

Despite efforts to address HIV-infection, adolescents and young peoples’ (AYP) engagement in interventions remain suboptimal. Guided by a risk protection framework we describe factors that support positive and negative experiences of HIV and SRH interventions among AYP in rural KwaZulu-Natal, South Africa, using data from: community mapping; repeat semi-structured individual interviews (n = 58 in 2017, n = 50 in 2018, n = 37 in 2019–2020); and group discussions (n = 13). AYP who had appropriate and accurate HIV-and SRH-related information were reported to use health-care services. Responsive health-care workers, good family and peer relationships were seen to be protective through building close connections and improving self-efficacy to access care. In contrast to cross-generational relationships with men, alcohol and drug use and early pregnancy were seen to put AYP at risk. Policies and interventions are needed that promote stable and supportive relationships with caregivers and peers, positive social norms and non-judgemental behaviour within clinical services

Implementing an engineering field testing platform for sustainable non-sewered sanitation prototypes

Researchers globally are developing sanitation solutions that make faecal waste safe, are affordable, do not require external power, water or sewer connections and that recover and reuse water, energy and nutrients. The Engineering Field Testing platform is a collaboration between the Pollution Research Group at the University of KwaZulu-Natal, eThekwini Water and Sanitation and a private company, Khanyisa Projects, which provides a supportive space to test early engineering concepts in a real world environment, while still under the control of technology developers. Local teams of engineers, scientists and social scientists support technology developers through site selection, community engagement, ethical approval, site preparation, installation and commissioning, sampling, testing and feedback and decommissioning. This ensures that locally relevant risks can be identified and mitigated. The concentration of prototypes being tested in a single location allows support resources and expertise to be pooled and increases collaboration to overcome common challenges
