RESUMO

This dataset expresses the experimental data on the batch adsorption of ciprofloxacin and lamivudine from synthetic solution using jamun seed (JS) (Syzygium cumini) biochar. Independent variables including concentration of pollutants (10-500 ppm), contact time (30-300 min), adsorbent dosage (1-1000 mg), pH (1-14) and adsorbent calcination temperature (250,300, 600 and 750 °C) were studied and optimized using Response Surface Methodology (RSM). Empirical models were developed to predict the maximum removal efficiency of ciprofloxacin and lamivudine, and the results were compared with the experimental data. The removal of polutants was more influenced by concentration, followed by adsorbent dosagage, pH, and contact time and the maximum removal reached 90%.

RESUMO

Illicit drug abuse and addiction are universal issues requiring international cooperation and interdisciplinary and multisectoral solutions. These addictive substances are utilized for recreational purposes worldwide, including in sub-Saharan Africa. On the other hand, conventional wastewater treatment facilities such as waste stabilization ponds lack the design to remove the most recent classes of pollutants such as illicit drug abuse. As a result, effluents from these treatment schemes contaminate the entire ecosystem. Public health officials are concerned about detecting these pollutants at alarming levels in some countries, with potential undesirable effects on aquatic species and increased health hazards through exposure to contaminated waters or recycling treated or untreated effluents in agriculture. Contaminants including illicit substances enter the environment by human excreta following illegal intake, spills, or through direct dumping, such as from clandestine laboratories, when their manufacturer does not follow accepted production processes. These substances, like other pharmaceuticals, have biological activity and range from pseudopersistent to highly persistent compounds; hence, they persist in the environment while causing harm to the ecosystem. The presence of powerful pharmacological agents such as cocaine, morphine, and amphetamine in water as complex combinations can impair aquatic organisms and human health. These compounds can harm human beings and ecosystem health apart from their low environmental levels. Therefore, this article examines the presence and levels of illicit substances in ecological compartments such as wastewater, surface and ground waters in sub-Saharan Africa, and their latent impact on the ecosystem. The information on the occurrences of illicit drugs and their metabolic products in the sub-Saharan Africa environment and their contribution to pharmaceutical load is missing. In this case, it is important to research further the presence, levels, distribution, and environmental risks of exposure to human beings and the entire ecosystem.

RESUMO

Menstrual hygiene management is an important determinant for girls' educational outcomes. We develop a method of cross-sectional analysis that quantifies the relative importance of four distinct mechanisms: material, biological, social and informational constraints and consider four main schooling outcomes: absenteeism, early departure, concentration and participation. We use survey data from 524 female students enrolled in four co-educational secondary schools in Northern Tanzania. Average age at first period is 14.2 years (standard deviation = 1.1, range 9-19). Information is the least binding constraint: 90-95% of girls report they received information about menstruation and how to manage it. In contrast, biological constraints are hindering: (i) the distribution of menstrual cramps and pain is bifurcated: most girls report very light or very strong pain (rather than moderate) with considerable educational impacts for girls in the latter group, (ii) irregular cycles (62%) and difficulty predicting the cycle (60%) lead to stress and uncertainty. Socio-cultural constraints are binding as 84% would feel shame if male peers knew their menstrual status, and 58% fear being teased over periods. Material constraints include prohibitive costs: girls spending between 12-70% of the daily national poverty line (6,247 TSH per day) on pads during their period. However, we discern no statistically significant relationship between access to pads and absenteeism. In contrast, biological and socio-cultural constraints as well as lack of sanitary infrastructure have significant effects on absenteeism. The results have several implications. First, sanitary pad interventions should consider participation and concentration as main outcomes, in addition to absenteeism. Second, biological (menstrual cramps and pain) and socio-cultural (fear, stigma) constraints are drivers of menstruation-related absenteeism and participation in the classroom and need to be evaluated in trials. We suggest exploring analgesic use, alternative pain-management techniques, menstrual cycle tracking technologies, and social programming in future trials.

RESUMO

Emerging evidence suggests that menstruation-related teasing is a common experience among adolescent girls with ramifications on their school participation, yet empirical evidence on the prevalence and determinants of period teasing in schools remain scarce. Menstrual hygiene research and policies almost exclusively focus on girls and women, leading to a dearth of knowledge of male attitudes. We conducted the first quantitative survey of period teasing in schools in sub-Saharan Africa, focusing on 432 male and 524 female students in four co-educational secondary schools in northern Tanzania. Period teasing is prevalent; 13% of girls have experienced period teasing, and more than 80% fear being teased, especially by male classmates. Girls' fears are associated with insufficient menstrual hygiene management resources and practices. Girls cope by reducing school attendance, participation, and concentration in the classroom during periods. Boys engage in period teasing because they perceive periods as embarrassing, especially visible markers of periods (odor or stains). Social norms, such as peer behavior and home restrictions on menstruating women, are associated with more teasing. Boys believe it is strongly inappropriate for girls to reveal period status or to discuss periods with males, including male teachers. In contrast, boys are well informed about basic biological facts of menstruation (scoring 60% on a knowledge quiz, not statistically different from the girls) and have received information from school curricula and health workers. Lack of suitable menstrual hygiene practices and restrictive social norms is correlated with period teasing, which hinders gender equality in educational opportunities. Providing narrowly bio-medical focused education about menstruation may not be enough to reduce period teasing in contexts with period stigma.

RESUMO

Bottom-up public health interventions are needed which are built on an understanding of community perspectives. Project SHINE is a community-based participatory action research intervention focused on developing sustainable water, sanitation, and hygiene strategies with Maasai pastoralists in Tanzania. The aim of the study is to understand perceptions related to water quality and scarcity as well as to assess the potential of the Biosand Filter as a low-cost, low-tech water treatment option. To avoid unintended harms, the community was engaged in identifying potential harms and mitigation strategies prior to the implementation of the filter.Two in-depth interviews and two group discussions were analyzed using thematic content analysis, while three think tanks were analyzed using directed content analysis. The findings highlight a range of concerns regarding water scarcity and quality. The think tank approach was an effective means of engaging the community in identifying potential unintended harms across four dimensions: the physical, psychosocial, economic, and cultural contexts. In addition, two external themes emerged as salient: political harm and harm by omission.

RESUMO

Background: Inadequate training of health care workers responsible for the sterilization of surgical instruments in low- and middle-income countries compromises the safety of workers and patients alike. Methods: A mixed methods research study was initiated in the Lake Zone areas of Northwestern Tanzania in the summer of 2018. The goal was to identify the impact of education and training on sterile processing practices at ten hospitals. Quantitative data analyzed included hospital assessments of sterile processing practices prior to and 4 months after training, as well as participant test scores collected at the beginning of training, after 5 days of classes, and 4 months after mentorship was completed. Thematic analysis of interviews with participants 4 months post-training was completed to identify associated impact of training. Results: Improvement in test scores were found to be directly related to sterile processing training. The greatest sterile processing practice changes identified through hospital assessments involved how instruments were cleaned, both at point of use and during the cleaning process, resulting in rusted and discoloured instruments appearing as new again. Themes identified in participant interviews included: changes in practice, challenges in implementing practice changes, resource constraints, personal and professional growth, and increased motivation, confidence and responsibility. Conclusions: Providing education and follow up support for workers in sterile processing resulted in increased knowledge of best practices, application of knowledge in practice settings, and awareness of issues that need to be overcome to decrease risks for patients and health care workers alike. Further research is needed to identify the impact of mentorship on hospital sterile processing practices in order to provide clear direction for future spending on training courses.

RESUMO

OBJECTIVE: To identify factors predictive of pregnancy-related anxiety (PRA) among women in Mwanza, Tanzania. DESIGN: A cross-sectional study was used to explore the relationship between psychosocial health and preterm birth. SETTING: Antenatal clinics in the Ilemela and Nyamagana districts of Mwanza, Tanzania. PARTICIPANTS: Pregnant women less than or equal to 32 weeks' gestational age (n=212) attending the two antenatal clinics. MEASURES: PRA was measured using a revised version of the 10-item PRA Questionnaire (PRA-Q). Predictive factors included social support (Multidimensional Scale of Perceived Social Support), stress (Perceived Stress Scale), depression (Edinburg Postpartum Depression Scale) and sociodemographic data. Bivariate analysis permitted variable selection while multiple linear regression analysis enabled identification of predictive factors of PRA. RESULTS: Twenty-five per cent of women in our sample scored 13 or higher (out of a possible 30) on the PRA-Q. Perceived stress, active depression and number of people living in the home were the only statistically significant predictors of PRA in our sample. CONCLUSIONS: Our findings were contrary to most current literature which notes socioeconomic status and social support as significant factors in PRA. A greater understanding of the experience of PRA and its predictive factors is needed within the social cultural context of low/middle-income countries to support the development of PRA prevention strategies specific to low/middle income countries.

RESUMO

OBJECTIVES: To explore and understand the experiences and priorities of pregnant women living with fears and worries related to fetal/infant and maternal health, the birthing process and ability to parent the infant (ie, pregnancy-related anxiety (PRA)) in Mwanza, Tanzania. DESIGN: Descriptive phenomenological approach. SETTING: Two clinics in the Ilemela and Nyamagana districts of Mwanza. PARTICIPANTS: Pregnant and postpartum women who obtained high scores on a PRA scale during pregnancy in a larger quantitative study were contacted to participate in an interview (10 women, aged 18-34 years; 3 HIV positive). MEASURES: Semi-structured interviews were undertaken, with guiding questions related to the women's experience during pregnancy. The Colaizzi method was used with transcripts that had been translated and back translated from Swahili to English and then hand-coded by the interviewer, with independent review by another researcher to verify the analysis. RESULTS: PRA, as experienced by women in Mwanza, was a state of worry and concern, often causing physical symptoms, and disrupting personal sense of peace. While some themes in the women's experiences reflected the domains examined in the PRA scale used to identify potential participants, others such as lack of knowledge, partner relationship, interactions with the healthcare system, spirituality and fear of HIV/AIDS were otherwise missing. Their prominence in the participants' stories broadens our understanding of PRA. CONCLUSIONS: The realities and viewpoints of women in low-income and middle-income countries (LMIC) experiencing PRA are still relatively unknown. The findings from this study provided much-needed insight into the perspectives and priorities of women in Mwanza who have experienced PRA and further support the need to explore this phenomenon in other LMIC. The additional domains identified reinforce the need for a PRA tool that accurately and adequately capture the complexities of PRA for women in this region.

RESUMO

BACKGROUND: Psychosocial health problems, specifically depression during pregnancy, can have negative impact on birth outcomes, postnatal mental health of the mother, and infant health. Antenatal depression is more prevalent among women in low- and middle-income countries than among women in high-income countries. Risk factors for antenatal depression reported in the literature relate to pregnant women in South Asia. Consequently, this study assessed depression in pregnancy and related psychosocial risk factors among select pregnant women residing in Mwanza region, Northern Tanzania. METHODS: We analysed data from 397 pregnant women recruited from three antenatal clinics for the period June-August 2013 for this cross-sectional study. Women provided data at one time point during their pregnancy by completing the Edinburgh Postnatal Depression Scale and a structured questionnaire assessing psychosocial, demographic, and behavioural risk factors related to antenatal depression. Multiple logistic regression analysis was performed to determine the relationship between risk factors examined and antenatal depression. RESULTS: Overall, 33.8 % (n = 134) of pregnant women had antenatal depression. Pregnancy-related anxiety was associated with antenatal depression (odds ratio (OR) 1.36, 95 % confidence interval (CI) 1.23 to 1.5). Pregnant women with poor relationship with partner and low/moderate socio-economic status had the highest OR for antenatal depression (82.34, 95 % CI 4.47, 1516.60) after adjusting for other covariates. Pregnant women with poor relationship with partner and high socio-economic status had an OR of 13.48 (95 % CI 1.71, 106.31) for antenatal depression. "Reference" pregnant women were those with very good relationship with partner and high socio-economic status. CONCLUSIONS: High proportion of self-reported depression among select pregnant women attending antenatal clinics in Mwanza, Tanzania merit integrating depression assessment into existing antenatal care services. Health care providers need to assess pregnancy-related risk factors (pregnancy-related anxiety), socio-demographic factors (socio-economic status), and interpersonal risk factors (relationship with partner). Future research should appraise effectiveness of interventions that enhance partner relationships in reducing antenatal depression across all wealth distributions.
