Healthcare Workers' Experiences and Challenges in Managing Gender-Based Violence Among HIV-Positive Women Living in Southern, Tanzania: A Qualitative Study.

Introduction: Healthcare workers (HCW) play an important role in managing women living with HIV (WLHIV) with gender-based violence (GBV) experience, but little is known about their experience in screening and managing GBV among WLHIV. This study explored the perceptions and experience of the HCWs on screening and managing GBV cases among WLHIV. Patients and Methods: We performed a descriptive phenomenological qualitative study to elicit the views and experience of HCW on GBV screening and management for WLHIV. The study was conducted in the semi-urban setting in Morogoro Region, Tanzania. Ten in-depth interviews (IDIs) were administered to HCW selected purposefully based on their roles at an HIV care and treatment center. Data were transcribed using patterns matching study aim and then merged into relevant themes for analysis and interpretation. NVIVO software version 12 was used for data coding and analysis. Results: We found that HCW experienced multiple challenges in GBV screening and management, including limited capacity for GBV screening and management; inadequate training on assessment and handling GBV cases, limited resources (time, GBV guidelines and screening tools), inadequate GBV referral and monitoring systems; referral forms for GBV survivors to social support centers and follow-up mechanisms to trace survivors, mental aspects; HCWs' fear of being stressed by listening to women's' GBV traumatic experiences, HCWs' fear of causing problems to the women's families and HCW biased notions on women disclosure of GBV; the believes that women will not report their GBV experiences. Conclusion: We identified context-specific challenges preventing HCW to deliver optimal services of GBV to WLHIV, stressing the necessity to strengthen HCW capacity and resources for GBV services and to integrate psychosocial services into HIV care. Policy and programs should be developed to support GBV screening and management for WLHIV.

Community perception of the autodissemination of pyriproxyfen for controlling malaria vectors in south-eastern Tanzania.

BACKGROUND: The efficacy of the autodissemination of pyriproxyfen to control malaria vectors has been demonstrated under semi field environment in Tanzania. However, the information on how best communities should be engaged for its routine and large-scale adoption are lacking. This study assessed the community's level of knowledge, perceptions, acceptability of the autodissemination of pyriproxyfen, and the perceived risks on the safety of pyriproxyfen on the environment. METHODS: This was a concurrent mixed methods study, comprised of a community-based survey of 400 household representatives and eight focus group discussions (FGDs). The study was conducted in two villages in Mlimba district in south-eastern Tanzania between June and August 2022. For the quantitative data analysis, descriptive statistics were applied using R software, while inductive approach was used for qualitative data analysis, using NVivo software. RESULTS: Knowledge on autodissemination of pyriproxyfen approach was found to be relatively low among both the FGD respondents and surveyed community members (36%, n = 144). Nevertheless, when it was explained to them, the envisioned community support for the autodissemination approach was relatively high (97%, n = 388). One of the major perceived benefits of the autodissemination of pyriproxyfen was the reduction of malaria-transmitting mosquitoes and associated malaria transmission. Environmental impact of pyriproxyfen on non-target organisms and health risk to children were among the major concerns. When provided with information on the safety and its utilization particularly through autodissemination approach, 93.5% (n = 374) of the survey respondents said that they would allow the PPF-contaminated pots to be placed around their homes. Similarly, FGD respondents were receptive towards the autodissemination of pyriproxyfen, but emphasized on the need for raising awareness among community members before related field trials. CONCLUSION: This study indicates a low knowledge but high support for scaling up of the autodissemination of pyriproxyfen as a complementary tool for malaria control in rural Tanzania. The Findings of this study suggest that community sensitization activities are required to improve the community's acceptability and trust of the approach before respective field trials.

Sterilized Anopheles funestus can autodisseminate sufficient pyriproxyfen to the breeding habitat under semi-field settings.

BACKGROUND: Anopheles funestus, the main malaria vector, prefer to oviposit in permanent and/or semi-permanent breeding habitats located far from human dwellings. Difficulties in identifying and accessing these habitats jeopardize the feasibility of conventional larviciding. In this way, a semi-field study was conducted to assess the potential of autodissemination of pyriproxyfen (PPF) by An. funestus for its control. METHODS: The study was conducted inside a semi-field system (SFS). Therein, two identical separate chambers, the treatment chamber with a PPF-treated clay pot (0.25 g AI), and the control chamber with an untreated clay pot. In both chambers, one artificial breeding habitat made of a plastic basin with one litre of water was provided. Three hundred blood-fed female An. funestus aged 5-9 days were held inside untreated and treated clay pots for 30 min and 48 h before being released for oviposition. The impact of PPF on adult emergence, fecundity, and fertility through autodissemination and sterilization effects were assessed by comparing the treatment with its appropriate control group. RESULTS: Mean (95% CI) percentage of adult emergence was 15.5% (14.9-16.1%) and 70.3% (69-71%) in the PPF and control chamber for females exposed for 30 min (p < 0.001); and 19% (12-28%) and 95% (88-98%) in the PPF and control chamber for females exposed for 48 h (p < 0.001) respectively. Eggs laid by exposed mosquitoes and their hatch rate were significantly reduced compared to unexposed mosquitoes (p < 0.001). Approximately, 90% of females exposed for 48 h retained abnormal ovarian follicles and only 42% in females exposed for 30 min. CONCLUSION: The study demonstrated sterilization and adult emergence inhibition via autodissemination of PPF by An. funestus. Also, it offers proof that sterilized An. funestus can transfer PPF to prevent adult emergence at breeding habitats. These findings warrant further assessment of the autodissemination of PPF in controlling wild population of An. funestus, and highlights its potential for complementing long-lasting insecticidal nets.
