RESUMO

Background: Approximately 15 million children are born each year prematurely, representing more than 10 percent of all childbirths worldwide. Prematurity is an acute event and the leading cause of death among newborns and children under five. Sixty percent of these premature deaths occur in Sub-Saharan Africa and Southeast Asia. Objective: The current study aimed to explore and understand women's experiences and perceptions regarding giving birth prematurely at the National Hospital of Muhimbili in Dar es Salaam, Tanzania. Method: A qualitative method, using Interpretive Phenomenological Analysis approach was chosen to understand and describe the women's experiences. A semi-structured guide was used during the interviews. All interviews were audio-recorded and transcribed verbatim. Findings: Eight in-depth interviews were conducted. The analysis revealed three superordinate themes: (a) Emotional turmoil: unmet expectations shattering maternal identity, emotional distress, and loss of hope; (b) Adapting to preterm birth and challenges: the unexpected situation, lack of proper care, strenuous breastfeeding routines, and socioeconomic challenges; (c) Significance of proper care and emotional support: good maternal care, mother-to-mother and family support. Conclusion: This study provided a deeper understanding of women's experiences and perceptions of premature childbirth. The current study indicated the importance of caregivers' awareness of the women's emotional distress, their need to adapt to a sudden unexpected situation, and the necessity of emotional support.

RESUMO

BACKGROUND: The World Health Organization (WHO) reported an estimated 249 million malaria cases globally in 2023, of which 94% were reported from Africa. Tanzania, a Sub-Saharan African country, has an exceptionally high malaria prevalence (3.6 million in 2023). The aim of the present study was to assess malaria prevalence rates in the Arusha Region, northern Tanzania. This region is famous for its national parks and wildlife reserves, and it is visited by thousands of tourists from all over the world each year. The assessment of malaria prevalence in the region is important in the context of the necessity to administer antimalarial chemoprophylaxis to international travellers. MATERIAL AND METHODS: The study group consisted of 101 people, residents of the Karatu District in the Arusha Region, aged between 1 and 73 years, who volunteered to participate in the screening. Phase I of the study was conducted in July 2022 in the Karatu Lutheran Hospital in Karatu Town (located close to the Ngorongoro Conservation Area and the Serengeti National Park). During this phase a venous blood sample was collected from each patient. The samples were tested for malaria using a rapid diagnostic test (mRDT); the same samples were also used to measure haemoglobin concentration and next they were applied onto the Whatman FTA micro cards for further molecular diagnostics in Poland (phase II). RESULTS: mRDT detected two (2.0%) infections caused by Plasmodium (the etiological factor of malaria), the molecular tests (RT-PCR) confirmed the two positive results by mRDT but also detected infections in six other samples (7.9% in total). The study found that six patients were infected with the Plasmodium falciparum species, while two other subjects had co-infections (P. falciparum + P. ovale, P. falciparum + P. vivax + P. malariae). CONCLUSIONS: The study findings confirm the prevalence of malaria in areas located close to national parks in northern Tanzania and support the use of antimalarial chemoprophylaxis in international travellers visiting the area. The present study found co-infections caused by four different species of Plasmodium species which supports the prevalence of different parasitic species in Sub-Saharan Africa and is in line with CDC reports but contrary to WHO reports which estimate that 100% of malaria cases in Sub-Saharan Africa are caused by P. falciparum.

RESUMO

Objectives: Chronic conditions and multimorbidity affect care needs and prevention opportunities. Methods: We studied 2,246 men and women aged ≥40 years within the Dar es Salaam Urban Cohort Study from June 2017 to July 2018. Seventeen chronic conditions were assessed based on self-report, body and blood pressure measurement, blood tests, and screening instruments. Results: Hypertension (51.3%), anemia (34.1%), obesity (32.2%), diabetes (31.6%), depressive symptoms (31.5%), low grip strength (21.2%), and ischemic heart disease (11.9%) were widespread. Multimorbidity was common (73.7%). Women had higher odds of obesity, ischemic heart disease, and high cholesterol (adjusted OR: 2.08-4.16) and lower odds of underweight, low grip strength, alcohol problems, and smoking (adjusted OR: 0.04-0.45). Ten years of age were associated with higher odds of low grip strength, cognitive problems, hypertension, kidney disease, chronic cough, diabetes, high cholesterol, ischemic heart disease, and multimorbidity (adjusted OR: 1.21-1.81) and lower odds of HIV infection (adjusted OR: 0.51). Conclusion: We found a higher prevalence of multimorbidity than previously estimated for middle-aged and elderly people in sub-Saharan Africa. The chronic conditions underlying multimorbidity differed by sex.

RESUMO

Background: The burden and risk of developing chronic kidney disease (CKD) among patients with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) is higher than in the general population. This study aimed to determine prevalence of and associated factors with CKD among adults infected with human immunodeficiency virus at tertiary hospitals in Dodoma, Tanzania. Method: ology: A cross-sectional study was carried out between November 2022 to April 2023. Patients' demographic data, and clinical measurements were obtained on the day of the visit. Laboratory investigations were performed as standard of care. Descriptive and inferential analyses were performed, and variables associated with CKD were identified by multivariable logistic regression. Results: A total of 223 patients were enrolled, with a median age of 47 (IQR 38-56) years, and 72.2 % were female. The CKD prevalence was 23.3 % whereby 18.4 % had CKD stage 3a, 4.5 % had CKD stage 3 b, and 0.4 % had CKD stage 4. CKD was observed largely among patients with obesity (34.15 %), anemia (29.41 %), hypertension (45.00 %), and diabetes mellitus (50.00 %). Variables with higher odds for CKD after adjusted analysis were hypertension (OR 3.03, 95 %% CI 1.29-7.11, P = 0.0109), diabetes mellitus (OR 4.50, 95 % CI 1.35-15.03, P = 0.0144), obesity (OR 3.07, 95 % CI 1.11-8.47, P = 0.0301), anaemia (OR 2.42, 95 % CI 1.12-5.26, P = 0.0252) and for each one-unit increase in age (years), there was statistically significant increase in the odds of having CKD by 1.084 folds (OR = 1.084, 95 % CI 1.039-1.131, p = 0.0002). Conclusion: The prevalence of CKD among patients with HIV/AIDS is high. Age, obesity, anaemia, hypertension, and diabetes mellitus were strongly associated with CKD suggesting a need for integrating initiatives for non-communicable disease control in this population.

RESUMO

AIMS: Methadone maintenance therapy (MMT) exhibits significant variability in pharmacokinetics and clinical response, partly due to genetic variations. However, data from sub-Saharan African populations are lacking. We examined plasma methadone variability and pharmacogenetic influences among opioid-addicted Tanzanian patients. METHODS: Patients attending MMT clinics (n = 119) in Tanzania were genotyped for common functional variants of the CYP3A4, CYP3A5, CYP2A6, CYP2B6, CYP2C19, CYP2D6, ABCB1, UGT2B7 and SLCO1B1 genotypes. Trough plasma concentrations of total methadone, S-methadone (S-MTD) and R-methadone (R-MTD), with their respective metabolites, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), were quantified using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The methadone-to-EDDP metabolic ratio (MMR) was used to categorize the phenotype. RESULTS: The proportions of MMR-predicted ultrarapid, extensive, intermediate and slow methadone metabolizer phenotypes were 2.5%, 58.2%, 23.7% and 15.6%, respectively. CYP2B6 genotype significantly correlated with S-methadone (P = .006), total methadone (P = .03), and dose-normalized methadone plasma concentrations (P = .001). Metabolic ratios of R-methadone (R-MTD/R-EDDP), S-methadone (S-MTD/S-EDDP), and total methadone (MMR) were significantly higher among patients homozygous for defective variants (*6 or *18) than heterozygous or CYP2B6*1/*1 genotypes (P < .001). The metabolic ratio for S-MTD and total methadone was significantly higher among ABCB1c.3435T/T than in the C/C genotype. No significant effect of CYP2D6, CYP2C19, CYP3A4, CYP3A5, CYP2A6, UGT2B7 and SLCO1B1 genotypes on S-methadone, R-methadone, or total methadone was observed. CONCLUSIONS: Approximately one in six opioid-addicted Tanzanian patients are methadone slow metabolizers, influenced by genetic factors. Both the CYP2B6 and ABCB1 genotypes are strong predictors of methadone metabolic capacity and plasma exposure. Further investigation is needed to determine their predictive value for methadone treatment outcomes and to develop genotype-based dosing algorithms for safe and effective therapy.

RESUMO

OBJECTIVE: Understanding microbiota colonizing ocular surfaces is key to expedite antibiotic prophylactic options for ocular surgeries, and therefore, prevent subsequent surgical site infections (SSIs). To fill this critical gap, we aimed at determining the prevalence and antibiotic susceptibility patterns of bacteria colonizing the external ocular surfaces of 224 patients undergoing ocular surgeries at Bugando Medical Centre (BMC) in Mwanza, Tanzania between May and August 2023. RESULTS: The study participants had a median age of 62.5 (interquartile range: 39.5-75.0) years. A total of 78.1% (175/224) ocular swabs were culture positive yielding 196 bacterial isolates. Staphylococcus epidermidis [43.4% (n = 85)], Staphylococcus aureus [21.9% (n = 43)] and Pseudomonas aeruginosa [14.3% (n = 28)] were the most common bacteria. There were low proportions of resistance among predominant Gram-positive and Gram-negative bacteria to gentamicin (≤ 25.0%), and similarly, low resistance among Gram negative bacteria was observed against 3rd generation cephalosporins (≤ 25.0%) and piperacillin-tazobactam (0.0%). Variable resistance profiles were notable to the most commonly used antibiotics (ciprofloxacin and tetracycline: 0.0-66.7%). Our findings underscore an urgent need to revisit antibiotic prophylactic guidelines for ocular surgeries in this tertiary hospital, and calls for prospective evaluation of incident SSIs post-ocular surgeries to guide specific management.

RESUMO

INTRODUCTION: Respirable crystalline silica (RCS) exposures in tanzanite gem mining have been linked to tuberculosis and silicosis among miners. We conducted a plot study to assess RCS exposures and to introduce safer mining practices in one small-scale underground tanzanite mine. MATERIALS AND METHODS: Personal and area air samples for RCS were collected during tanzanite mining operations before and after improved work practices employed to reduce exposures and analyzed using X-ray diffraction. Area samples were collected at the rest area, located approximately 300 m underground and 100 m from other work activities. Improved practices included the use of wet drilling methods and drilling with new bits. RESULTS: A total of 33 personal and 4 area air samples were collected. Pre-intervention, mean exposures for all operations, drilling operations, non-drilling activities, and area samples were 122 mg/m3, 247 mg/m3, 34.3 mg/m3, and 1.95 mg/m3, respectively which exceeded the U.S. OSHA Permissible Exposure Limit (PEL) by 2,440 times for all operations, by 4,946 times for drilling operations, by 686 times for non-drilling activities and 39 times for area samples collected at an underground rest area. The post-intervention results showed a 99% reduction of RCS exposures for wet drilling operations, 98.5% reduction for non-drilling activities, and 36% reduction for area samples. Despite improvements, post-intervention RCS exposures during drilling had a mean of 2.08 mg/m3 or more than 41 times the OSHA PEL. CONCLUSIONS: We successfully piloted a program to work with small-scale tanzanite miners to reduce RCS exposures and raise awareness about the occupational health risks of RCS, though additional measures are recommended to further reduce RCS exposures. Similar programs should be taken to scale throughout underground mining sites in Tanzania and other countries.

RESUMO

Bacterial zoonoses are established causes of severe febrile illness in East Africa. Within a fever etiology study, we applied a high-throughput 16S rRNA metagenomic assay validated for detecting bacterial zoonotic pathogens. We enrolled febrile patients admitted to 2 referral hospitals in Moshi, Tanzania, during September 2007-April 2009. Among 788 participants, median age was 20 (interquartile range 2-38) years. We performed PCR amplification of V1-V2 variable region 16S rRNA on cell pellet DNA, then metagenomic deep-sequencing and pathogenic taxonomic identification. We detected bacterial zoonotic pathogens in 10 (1.3%) samples: 3 with Rickettsia typhi, 1 R. conorii, 2 Bartonella quintana, 2 pathogenic Leptospira spp., and 1 Coxiella burnetii. One other sample had reads matching a Neoerhlichia spp. previously identified in a patient from South Africa. Our findings indicate that targeted 16S metagenomics can identify bacterial zoonotic pathogens causing severe febrile illness in humans, including potential novel agents.

RESUMO

Beyond Bias was an intervention introduced in Burkina Faso, Pakistan and Tanzania, with the aim of reducing health worker bias toward young, unmarried and nulliparous women seeking family planning services. This study used qualitative methods - based on interviews with health workers who participated in the intervention, managers at health facilities that participated in the intervention, and policy and program stakeholders at the national level - to understand implementation experiences with the intervention. The results offer insights for organizations or countries seeking to implement Beyond Bias or similar programs, and point to some other key implementation challenges for multi-component interventions in lower-resource settings. The intervention, developed using a human-centered design approach, was seen as key for successful implementation but there were logistical challenges. The digital intervention was disruptive and distracting to many. In addition, the non-financial rewards intervention was perceived as complex, and some participants expressed feeling discouraged when they did not receive a reward. Beyond Bias did not sufficiently attend to the "outer setting," and this was perceived as a major implementation barrier as it limited individuals' capacity to fully achieve the desired behavior change; for example, space constraints meant that some health facilities could not ensure private services for all clients. There were scalability concerns related to cost, and there is uncertainty whether diversity of contexts (within and across countries) might constrain implementation of Beyond Bias at scale.

RESUMO

BACKGROUND: Ebola Virus Disease (EVD) is a rare but contagious disease caused by Ebola Virus (EBOV). The first Ebola outbreaks were reported in the Democratic Republic of Congo (DRC) before subsequent reported cases in Western and East African countries, including Uganda, which borders Tanzania. Proximity to EVD-infected countries raises the prospect of cross-border transmission, raising alarm in Tanzania. This study aimed to explore the cultural practices likely to prevent or escalate EVD transmission in the event of its outbreak in the country. METHODS: This rapid ethnographic assessment employed observation, interviews, and focus group discussions to collect data from people with diverse characteristics in five regions of Tanzania Mainland namely, Kagera, Kigoma, Mwanza and Songwe regions and Zanzibar Island. The qualitative data was then subjected to thematic analysis. FINDINGS: Cultural practices may escalate the transmission of EVD and hinder its prevention and control. These cultural practices include caring sick people at home, confirmation of death, mourning, and body preparation for burial. Communal life, ceremonies, and social gatherings were other aspects observed to have the potential for compounding EVD transmission and hindering its containment in case of an outbreak. CONCLUSION: Cultural practices may escalate EVD transmission as identified in the study settings. As such, Risk Communication and Community Engagement (RCCE) activities should be interventionist in transforming cultural practices that may escalate the spread of EVD as part of preparedness, prevention, and control efforts in the event of an outbreak.

RESUMO

Powerful pharmaceuticals are readily available for purchase throughout Tanzania and global health policy makers decry this situation as dangerous and disordered, as if no rules govern the use of drugs in Africa. In the prevailing global health understanding, 'truth' lies in the laboratory science that goes into the making and proper prescription of drugs, and such deviations as 'overuse' and 'misuse' result from the fact that locals supposedly misunderstand what these drugs are and how they should be used. However, my ethnographic research in Tanzania reveals that embodied epistemologies frequently enable medical practitioners and patients to evaluate the quality of various drugs and to identify chakachua (substandard or adulterated) pharmaceuticals through their material and sensory qualities-a practice I conceptualize as a form of 'fugitive science' (Rusert 2017). In light of this, I analyze the WHO's National Action Plan for Antimicrobial Resistance in Tanzania, demonstrating how such global health policies disregard this knowledge, employing neocolonial rhetoric that presents 'ignorance' and 'lack of hygiene' as the sources of growing antimicrobial resistance while simultaneously obscuring structural inequalities. I argue that such forms of global health surveillance operate through the logics and epistemologies of war (Chow 2006; Terry 2017) in ways that render populations in the Global South into threats and targets. I conclude by suggesting that fugitive science can work as counter-evidence to health security frameworks and, as such, represents a furtive form of resistance to these militarized logics.

RESUMO

BACKGROUND: Hypertensive disorders of pregnancy (HDP) are a significant cause of maternal mortality worldwide. The classification and treatment of hypertension in pregnancy remain debated. We aim to compare the effectiveness of the revised 2017 ACC/AHA blood pressure threshold in predicting adverse pregnancy outcomes. METHODS: We conducted a secondary data analysis of the Alliance for Maternal and Newborn Health Improvement (AMANHI) biorepository study, including 10,001 pregnant women from Bangladesh, Pakistan, and Tanzania. Blood pressure was measured using validated devices at different antenatal care visits. The blood pressure readings were categorized as: normal blood pressure (systolic blood pressure (sBP) < 120 mm Hg and diastolic blood pressure (dBP) < 80 mm Hg), elevated blood pressure (sBP 120-129 and dBP < 80), stage 1 hypertension (sBP 130-139 or dBP 80-89, or both), and stage 2 hypertension (sBP ≥ 140 or dBP ≥ 90, or both). We estimated risk ratios for stillbirths and preterm births, as well as diagnostic test properties of both the pre-existing JNC7 (≥ 140/90) and revised ACC/AHA (≥ 130/80) thresholds using normal blood pressure as reference group. RESULTS: From May 2014 to June 2018, blood pressure readings were available for 9,448 women (2,894 in Bangladesh, 2,303 in Pakistan, and 4,251 in Tanzania). We observed normal blood pressure in 70%, elevated blood pressure in 12.4%, stage 1 hypertension in 15.2%, and stage 2 hypertension in 2.5% of the pregnant women respectively. Out of these, 310 stillbirths and 9,109 live births were recorded, with 887 preterm births. Using the ACC/AHA criteria, the stage 1 hypertension cut-off revealed 15.3% additional hypertension diagnoses as compared to JNC7 criteria. ACC/AHA defined hypertension was significantly associated with stillbirths (RR 1.8, 95% CI 1.4, 2.3). The JNC 7 hypertension cut-off of ≥ 140/90 was significantly associated with a higher risk of preterm births (RR 1.6, 95% CI 1.2, 2.2) and stillbirths (RR 3.6, 95% CI 2.5, 5.3). Both criteria demonstrated low sensitivities (8.4 for JNC-7 and 28.1 for ACC/AHA) and positive predictive values (11.0 for JNC7 and 5.2 for ACC/AHA) in predicting adverse outcomes. CONCLUSION: The ACC/AHA criteria (≥ 130/80) identified additional cases of hypertension but had limited predictive accuracy for stillbirths and preterm births, highlighting the ongoing need for improved criteria in managing pregnancy-related hypertension.

RESUMO

Capability wellbeing can potentially provide a holistic outcome for health economic evaluation and the capability approach seems promising for African countries. As yet there is no work that has explored the evaluative space needed for health and care decision making at the whole population level and procedures that merely translate existing measures developed in the global north to contexts in the global south risk embedding structural inequalities. This work seeks to elicit the concepts within the capability wellbeing evaluative space for general adult populations in Tanzania and Malawi. Semi-structured interviews with 68 participants across Tanzania and Malawi were conducted between October 2021 and July 2022. Analysis used thematic coding frames and the writing of analytic accounts. Interview schedules were common across the two country settings, however data collection and analysis were conducted independently by two separate teams and only brought together once it was clear that the data from the two countries was sufficiently aligned for a single analysis. Eight common attributes of capability wellbeing were found across the two countries: financial security; basic needs; achievement and personal development; attachment, love and friendship; participation in community activities; faith and spirituality; health; making decisions without unwanted interference. These attributes can be used to generate outcome measures for use in economic evaluations comparing alternative health interventions. By centring the voices of Tanzanians and Malawians in the construction of attributes that describe a good life, the research can facilitate greater equity within economic evaluations across different global settings.

RESUMO

BACKGROUND: Pharmacogenomics of hydroxyurea is an important aspect in the management of sickle cell disease (SCD), especially in the era of genomic medicine. Genetic variations in loci associated with HbF induction and drug metabolism are prime targets for hydroxyurea (HU) pharmacogenomics, as these can significantly impact the therapeutic efficacy and safety of HU in SCD patients. METHODS: This study involved designing of a custom panel targeting BCL11A, ARG2, HBB, HBG1, WAC, HBG2, HAO2, MYB, SAR1A, KLF10, CYP2C9, CYP2E1 and NOS1 as potential HU pharmacogenomics targets. These genes were selected based on their known roles in HbF induction and HU metabolism. The panel was designed using the Illumina Design Studio (Illumina, San Diego, CA, USA) and achieved a total coverage of 96% of all genomic targets over a span of 51.6 kilobases (kb). This custom panel was then sequenced using the Illumina MiSeq platform to ensure high coverage and accuracy. RESULTS: We are reporting a successfully designed Illumina (MiSeq) HU pharmacogenomics custom panel encompassing 51.6 kilobases. The designed panel achieved greater than 1000x amplicon coverage which is sufficient for genomic analysis. CONCLUSIONS: This study provides a valuable tool for research in HU pharmacogenomics, especially in Africa where SCD is highly prevalent, and personalized medicine approaches are crucial for improving patient outcomes. The custom-designed Illumina (MiSeq) panel, with its extensive coverage and high sequencing depth, provides a robust platform for studying genetic variations associated with HU response. This panel can contribute to the development of tailored therapeutic strategies, ultimately enhancing the management of SCD through more effective and safer use of hydroxyurea.

RESUMO

OBJECTIVE: To describe rates of retention in care and control of hypertension, diabetes and HIV among participants receiving integrated care services for a period of up to 24 months in East Africa. METHODS: Between 5 October 2018 and 23 June 2019 participants enrolled into a prospective cohort study evaluating the feasibility of integrated care delivery for HIV, diabetes and hypertension from a single point of care in Tanzania and Uganda (MOCCA study). Integrated care clinics were established in 10 primary healthcare facilities and care was provided routinely according to national guidelines. Initial follow-up was 12 months. Outcomes were rates of retention in care, proportions of participants with controlled hypertension (blood pressure <140/90 mmHg), diabetes (fasting blood glucose <7.0 mmol/L) and HIV (plasma viral load <1000 copies/ml). The study coincided with the COVID-19 pandemic response. Afterwards, all participants were approached for extended follow-up by a further 12 months in the same clinics. We evaluated outcomes of the cohort at the end of long-term follow-up. RESULTS: The MOCCA study enrolled 2273 participants of whom 1911 (84.5%) were retained in care after a median follow-up of 8 months (Interquartile range: 6.8-10.7). Among these, 1283/1911 (67.1%) enrolled for a further year of follow-up, 458 (24.0%) were unreachable, 71 (3.7%) reverted to vertical clinics (clinics providing services dedicated to study conditions), 31 (1.6%) died and 68 (3.6%) refused participation. Among participants who enrolled for longer follow-up, mean age was 51.4 ± 11.7 years, 930 (72.5%) were female and 509 (39.7%) had multiple chronic conditions. Overall, 1236 (96.3%) [95% confidence interval 95.2%-97.3%] participants were retained in care, representing 1236/2273 (54.3%) [52.3%-56.4%] of participants ever enrolled in the study. Controlled hypertension, diabetes and HIV at the end of follow-up was, 331/618 (53.6%) [49.5%-57.5%], 112/354 (31.6%) [26.8%-36.8%] and 332/343 (96.7%) [94.3%-98.4%] respectively. CONCLUSION: Integrated care can achieve high rates of retention in care long term, but control of blood pressure and blood sugar remains low.

RESUMO

Protected area management often depends heavily on law enforcement to secure compliance with rules. However, this can contribute to conflict between protected area authorities and local people, negatively affecting both human well-being and conservation outcomes. Compliance is affected by many factors, including whether those who enforce rules are perceived to do so fairly, as well as the perceived rule-related behavior of others. We used factorial survey experiments to explore how fair respondents living around protected areas in Indonesia and Tanzania perceive sanctions distributed by law enforcers to be. We presented scenarios to respondents to assess how crime type, offender characteristics, and corruption influenced their judgments regarding the fairness of administered sanctions. We also assessed how descriptive norms and corruption influenced individuals' willingness to obey protected area rules. Data were collected from 229 people in Indonesia and 217 in Tanzania. Results showed that in both locations, lawful sanctions, such as arrests or warnings, were perceived as fairer, and sanctions that involved corruption were perceived as least fair. Attitudes toward protected area rules, corruption, and descriptive norms all influenced people's willingness to comply, whereas multidimensional poverty did not. Our results highlight the need for conservation policy and practice to move beyond narratives that focus on the need for more law enforcement. To improve protected area compliance and secure better outcomes for people and nature, conservation must focus on ensuring the fair administration of rules and enhancing the legitimacy of rules themselves.


Mejoras en el cumplimiento alrededor de las áreas protegidas mediante la administración imparcial de reglas Resumen El manejo de áreas protegidas casi siempre depende de la aplicación de la ley para asegurar el cumplimiento de las reglas. Sin embargo, esto puede contribuir al conflicto entro las autoridades de las áreas protegidas y los locales, lo que afecta negativamente al bienestar humano y a los resultados de conservación. El cumplimiento se ve afectado por muchos factores, incluido si se percibe que quienes aplican las reglas lo hacen de manera imparcial, así como el comportamiento relacionado a las reglas de las demás. Aplicamos experimentos de censo factorial para explorar cómo los respondientes imparciales que viven en torno a las áreas protegidas en Indonesia y Tanzania perciben las sanciones distribuidas por los agentes de la ley. Les presentamos escenarios para analizar cómo el tipo de crimen, características del ofensor y la corrupción influyen sobre sus juicios con respecto a la imparcialidad de las sanciones administradas. También analizamos cómo las normas descriptivas y la corrupción influyen sobre la voluntad individual de obedecer las reglas del área protegida. Recolectamos los datos de 299 personas en Indonesia y 217 en Tanzania. Los resultados mostraron que, en ambas localidades, las sanciones legales, como arrestos o advertencias, eran percibidas como más justas, y las sanciones que involucraban corrupción eran percibidas como las menos justas. Todas las actitudes hacia las reglas de las áreas protegidas, la corrupción y las normas descriptivas influyeron sobre la voluntad de las personas para obedecer, mientras que la pobreza multidimensional no influyó. Nuestros resultados enfatizan la necesidad de que las políticas y prácticas de conservación vayan más allá de las narrativas que se enfocan en la necesidad de una mayor aplicación de la ley. Para incrementar el cumplimiento en las áreas protegidas y asegurar mejores resultados para las personas y la naturaleza, la conservación debe enfocarse en garantizar la administración imparcial de las reglas e incrementar su legitimidad.

RESUMO

Women's economic empowerment is recognized as a fundamental component of gender equality and global development. Despite a significant body of evidence highlighting the positive effects of women's labor force participation in low- and middle-income countries, relatively few studies have explored how caregivers of young children perceive women's economic empowerment in relation to childcare and family responsibilities. The objective of this study was to examine how mothers and fathers viewed the links between maternal employment and family caregiving dynamics specifically in terms of couples' relationships and parenting. We conducted in-depth interviews with 23 mothers and 29 fathers of young children under aged 2 years and 9 focus group discussions with mothers and fathers across 4 communities in Mwanza, Tanzania. Data were analyzed through both deductive and inductive approaches. Results revealed distinct gender differences in maternal versus paternal perceptions regarding women's engagement in income-generating activities. Mothers held favorable views towards employment and largely perceived positive effects on parenting, child, and family outcomes. On the other hand, most fathers were unsupportive of women's employment and held restrictive gender attitudes. Men feared a loss of power and perceived various negative consequences in terms of increased marital conflict, poorer maternal parenting, and worse child outcomes. Overall, this study revealed differences in maternal versus paternal perceptions about women's economic empowerment and its links with couples' relationships and parenting that were strongly shaped by gender attitudes. Women's economic empowerment programs that engage men to transform gender norms while incorporating program components to strengthen couples' relationships and promote positive parenting have potential for achieving family-wide benefits among mothers, fathers, and young children.

RESUMO

Objectives: This study aimed to understand the care needs, care arrangements and burden of care for people with dementia in Northern Tanzania. Methods: This was a cross-sectional, observational study. People with dementia and their carers (n = 53) were recruited from an outpatient clinic, and data on carer burden and independence in activities of daily living were collected. Associations with carer burden and characteristics were explored through non-parametric tests and regression analyses. Results: Thirty-six carers were female (68%). Levels of impairment in instrumental activities of daily living were high, with a median score of 38 out of 44 on the Identification and Intervention for Dementia in Elderly Africans - Instrumental Activities of Daily Living (IDEA-IADL). Carer burden was moderate with a median Zarit Burden Interview (ZBI) score of 46 out of 88. Being a female carer was associated with higher carer burden (odds ratio 3.68, 95% CI 1.04-12.99). Discussion: Carer burden was found to be higher than in previous studies based in low-and-middle income countries. Further research is needed to explore this difference, and to identify interventions to support care needs and reduce carer burden.

RESUMO

BACKGROUND: Staphylococcus pseudintermedius and S. aureus are important pathogens in dogs. This study established carrier rates, strain diversity and antimicrobial resistance of these bacteria among healthy dogs in Tanzania. RESULTS: Based on cultures of mouth and perineal swabs, 11.3% and 50.3% of 151 healthy dogs were carriers of S. aureus and S. pseudintermedius, respectively. Only four dogs (3%) carried meticillin-resistant S. aureus (MRSA), while none of the S. pseudintermedius strains were meticillin-resistant. 12 of 19 S. aureus strains tested were resistant to penicillin G, and resistance to enrofloxacin and tetracycline was also commonly detected. The most common resistances in 103 S. pseudintermedius strains tested were to penicillin G (28.2%) and tetracycline (22.3%). S. pseudintermedius strains showed 65 different random amplified polymorphic DNA (RAPD) fingerprints, and S. aureus strains belonged to eight different spa types, including two novel types (t18988 and t18989). MRSA strains carried SCCmec type V. CONCLUSIONS AND CLINICAL RELEVANCE: Healthy dogs in Tanzania were carriers of MRSA at low frequency, and half of the dogs carried S. pseudintermedius with high strain diversity.
