RESUMO

BACKGROUND: Although prostate cancer (Pca) screening plays important role in early diagnosis and reduction of mortality, Tanzanian men are relatively unscreened. We aimed to investigate Pca knowledge level and barriers to screening among at-risk men in northern Tanzania. METHODS: This community-based survey was conducted in northern Tanzania from May to September 2022, involving men age ≥40 years. Participants were invited by announcing in local churches, mosques, brochures, and social media groups. Participants attended a nearby health facility where survey questionnaires were administered. Knowledge level was measured on the Likert scale and scored as poor (<50 %) or good (≥50 %). RESULTS: A total of 6205 men with a mean age of 60.23 ± 10.98 years were enrolled in the study. Of these, 586 (9.5 %) had ever been screened for Pca. Overall, 1263 men (20.4 %) had good knowledge of Pca. Having health insurance, knowing at least 1 risk factor or symptoms of Pca, and hospital as the source of Pca information were significantly associated with ever being screened. The most common reasons for not being screened were a belief that they are healthy (n = 2983; 53.1 %), that Pca is not a serious disease (n = 3908; 69.6 %), and that digital rectal examination (DRE) as an embarrassing (n = 3634; 64.7 %) or harmful (n = 3047; 54.3 %) procedure. CONCLUSION: Having Pca knowledge, health insurance and hospital source of information were correlated with increased screening. False beliefs about DRE and the seriousness of Pca had negative effects on screening. Increasing community knowledge and universal health coverage would improve uptake of Pca screening.

RESUMO

BACKGROUND: HIV partner counselling and testing in antenatal care (ANC) is a crucial strategy to raise the number of males who know their HIV status. However, in many settings like Tanzania, male involvement in antenatal care remains low, and there is a definite need for innovative strategies to increase male partner involvement. This study was designed to evaluate the efficacy of mobile phone intervention increase male partner ANC attendance for HIV testing in Moshi municipal, Tanzania. METHODS: Between April and July 2022, we enrolled pregnant women presenting to a first ANC visit at Majengo and St. Joseph reproductive health facilities without their male partners. Eligible pregnant women were randomly assigned to invitation of their male partners either via phone calls, text messages from clinic staff and verbal invites from pregnant partners (intervention arm) or verbal invites only from the pregnant partners (control arm). Neither healthcare provider nor participant were blinded. The primary outcome was the proportion of male partners who attended ANC with their pregnant partners during a follow-up period of two consecutive visits. The secondary outcome measure was HIV testing among male partners following the invitation. Participants were analyzed as originally assigned (intention to treat). RESULTS: A total of 350 pregnant women presenting to ANC for the first time were enrolled, with 175 women enrolled in each arm. The efficacy of male attendance with their pregnant women following the invitations was 83.4% (147/175) in the intervention arm and 46.3% (81/175) in the control arm. Overall, the results suggest a positive and statistically significant average treatment effect among men who received mobile phone intervention on ANC attendance. For the secondary outcome, the percent of male partners who accepted HIV counselling and testing was 99.3% (146/147) in the intervention arm and 93.8% (76/81) in the control arm. Married men were having higher odds of ANC attendance compared with single men (aOR:6.40(3.26-12.56), Males with multigravida women were having lower odds of ANC attendance compared with primigravida women (aOR:0.17(0.09-0.33). CONCLUSION: The study demonstrates that supplementing verbal invitations with mobile phone calls and text messages from clinic staff can significantly increase male partner ANC attendance and HIV testing. This combined approach is recommended in improving ANC attendance and HIV testing of male partners who do not accompany their pregnant partners to antenatal clinics in the first visits.

RESUMO

INTRODUCTION: The SARS-CoV-2 (COVID-19) pandemic has strained healthcare systems and presented unique challenges for children requiring cancer care, particularly in low- and middle-income countries. This study aimed to assess the impact of the COVID-19 pandemic on access to cancer care for children and adolescents in Northern Tanzania. METHODS: In this cross-sectional study, we assessed the demographic and clinical characteristics of 547 pediatric and adolescent cancer patients (ages 0-19 years old) between 2016 and 2022 using the population-based Kilimanjaro Cancer Registry (KCR). We categorized data into pre-COVID-19 (2016-2019) and COVID-19 (2020-2022) eras, and performed descriptive analyses of diagnostic, treatment, and demographic information. A secondary analysis was conducted on a subset of 167 patients with stage of diagnosis at presentation. RESULTS: Overall admissions nearly doubled during the pandemic (n = 190 versus 357). The variety of diagnoses attended at KCMC increased during the pandemic, with only five groups of diseases reported in 2016 to twelve groups of diseases in 2021. Most patients were diagnosed at a late stage (stage III or IV) across eras, with the proportion of under-five years old patients increasing late-diagnoses from 29.4% (before the pandemic), 52.8% (during the pandemic), when compared to the overall cohort. Around 95% of children in this age category reported late-stage diagnosis during the pandemic. Six out of the twelve cancer site groups also reported an increase in late-stage diagnosis. During the pandemic, the proportion of children receiving surgery increased from 15.8 to 30.8% (p < 0.001). CONCLUSION: Childhood and adolescent cancer care changed in Northern Tanzania during the COVID-19 pandemic, with increased late-stage diagnoses presentations among younger patients and the increased use of surgical therapies in the context of a growing practice. Understanding the impact of the COVID-19 pandemic on pediatric and adolescent cancer care can help us better adapt healthcare systems and interventions to the emerging needs of children and adolescents with cancer in the midst of a health crisis.

RESUMO

Introduction: musculoskeletal (MSK) disorders account for approximately 20% of all years lived with disability worldwide however studies of MSK disorders in Africa are scarce. This pilot study aimed to estimate the community-based prevalence of MSK disorders, identify predictors, and assess the associated disability in a Tanzanian population. Methods: a cross-sectional study was conducted in one village in the Kilimanjaro region from March to June 2019. The Gait, Arms, Legs, Spine (GALS) or paediatric GALS (pGALS) examinations were used during household and school visits. Individuals positive in GALS/pGALS screening were assessed by the regional examination of the musculoskeletal system (REMS) and Modified Health Assessment Questionnaire (MHAQ). Results: among the 1,172 individuals enrolled in households, 95 (8.1%, 95% CI: 6.6 - 9.8) showed signs of MSK disorders using the GALS/pGALS examination and 37 (3.2%, 95% CI: 2.2 - 4.3) using the REMS. Among 682 schools enrolled children, seven showed signs of MSK disorders using the GALS/pGALS examination (1.0%, 95% CI: 0.4 - 2.1) and three using the REMS (0.4%, 95% CI: 0.0 - 1.3). In the household-enrolled adult population, female gender and increasing age were associated with GALS and REMS-positive findings. Among GALS-positive adults, increasing age was associated with REMS-positive status and increasing MHAQ score. Conclusion: this Tanzanian study demonstrates a prevalence of MSK disorders and identifies predictors of MSK disorders comparable to those seen globally. These findings can inform the development of rheumatology services and interventions in Tanzania and the design of future investigations of the determinants of MSK disorders, and their impacts on health, livelihoods, and well-being.

RESUMO

OBJECTIVES: The immune system of milk (ISOM) creates a mother-infant immune axis that plays an important role in protecting infants against infectious disease (ID). Tradeoffs in the immune system suggest the potential for both protection and harm, so we conceive of two dimensions via which the ISOM impacts infants: promotion of protective activity and control of activity directed at benign targets. High variability in ISOM activity across mother-infant dyads suggests investment the ISOM may have evolved to be sensitive to maternal and/or infant characteristics. We assessed predictors of appropriate and misdirected proinflammatory ISOM activity in an environment of high ID risk, testing predictions drawn from life history theory and other evolutionary perspectives. METHODS: We characterized milk in vitro interleukin-6 (IL-6) responses to Salmonella enterica (a target of protective immune activity; N = 96) and Escherichia coli (a benign target; N = 85) among mother-infant dyads in rural Kilimanjaro, Tanzania. We used ordered logistic regression and mixture models to evaluate maternal and infant characteristics as predictors of IL-6 responses. RESULTS: In all models, IL-6 responses to S. enterica increased with maternal age and decreased with gravidity. In mixture models, IL-6 responses to E. coli declined with maternal age and increased with gravidity. No other considered variables were consistently associated with IL-6 responses. CONCLUSIONS: The ISOM's capacities for appropriate proinflammatory activity and control of misdirected proinflammatory activity increases with maternal age and decreases with gravidity. These findings are consistent with the hypothesis that the mother-infant immune axis has evolved to respond to maternal life history characteristics.

RESUMO

BACKGROUND: IMPAACT 1077BF/FF compared the safety/efficacy of two HIV antiretroviral therapy (ART) regimens to zidovudine (ZDV) alone during pregnancy for HIV prevention. PROMISE found an increased risk of preterm delivery (<37 weeks) with antepartum triple ART (TDF/FTC/LPV+r or ZDV/3TC/LPV+r) compared to ZDV alone. We assessed the impact of preterm birth, breastfeeding and antepartum ART regimen on 24-month infant survival. METHODS: We compared HIV-free and overall survival at 24-months for liveborn infants by gestational age, time-varying breastfeeding status, and antepartum ART arm at 14 sites in Africa and India. Kaplan-Meier survival probabilities and Cox proportional hazards ratios (HR) were estimated. RESULTS: 3,482 live-born infants (568 [16 3%] preterm and 2,914 [83 7%] term) were included. Preterm birth was significantly associated with lower HIV-free survival (0·85; 95% CI: 0·82-0·88) and lower overall survival (0·89; 95% CI: 0·86-0·91) versus term birth (0·96; 95% CI: 0·95-0·96). Very preterm birth (<34 weeks) was associated with low HIV-free survival (0·65; 95% CI: 0·54-0·73) and low overall survival (0·66; 95% CI: 0·56-0·74). Risk of HIV infection or death at 24-months was higher with TDF-ART than ZDV-ART (adjusted HR 2·37; 95% CI: 1·21-4·64). Breastfeeding initiated near birth decreased risk of infection or death at 24 months (adjusted HR 0·05; 95% CI: 0·03-0·08) compared to not breastfeeding. CONCLUSION: Preterm birth and antepartum TDF-ART were associated with lower 24-month HIV-free survival compared to term birth and ZDV-ART. Any breastfeeding strongly promoted HIV-free survival, especially if initiated close to birth. Reducing preterm birth and promoting infant feeding with breastmilk among HIV/ARV-exposed infants remain global health priorities.

RESUMO

More young people are living in the world than ever before, 90% of whom reside in low and middle income countries (LMICs). To address their needs, it is critical to have sustainable youth engagement when determining policy and to advance effective implementation of youth-focused interventions. Youth Community Advisory Boards (CABs) are a sustainable mechanism to achieve this goal. This paper describes engagement with youth CAB members across four locations in Tanzania. To set youth CAB meeting agendas and priorities, we asked youth CAB members to write (using free text) the top five challenges faced by young people in their communities (highest to lower priority). The Google Forms survey link was presented at the May 2023 youth CAB meeting and disseminated through WhatsApp. The survey was completed by smartphone, tablet, or paper provided to the youth liaison for data entry. Results were translated from Swahili to English and coded using excel. Findings were then presented back to the youth CABs at the September 2023 meeting. At that meeting, youth CAB members were then asked to write (free text) potential solutions to the most commonly described challenges. The surveys had response rates of 90% (84/93) for challenges and 78% (71/93) for solutions. The number one reported challenge was unemployment and financial instability (45%). Gender based violence (13%), sexual reproductive health issues (8%), and alcohol and drug use (8%) were in the top four both by priority and frequency of report. Other important challenges included physical and mental health, malnutrition, relationships, education, and societal and environmental norms, among others. Solutions included job creation, improved education, expanded legal systems, youth-friendly health care services, and increased social support through peer networks and community support. The National Accelerated Action and Investment Agenda for Adolescent Health and Wellbeing (NAIA-AHW) 2021/22-2024/25 includes most, but not all, of these top challenges and solutions. Ensuring young people have a seat at the policy table is critical to effective youth-empowerment in health and other related programs. Including a youth CAB member to represent this collective in youth-related government activities is a sustainable model to achieve this goal.

RESUMO

Respectful maternity care (RMC) for women living with HIV (WLHIV) improves birth outcomes and may influence women's long-term commitment to HIV care. In this study, we evaluated the MAMA training, a team-based simulation training for labor and delivery (L&D) providers to improve RMC and reduce stigma in caring for WLHIV. The study was conducted in six clinical sites in the Kilimanjaro Region of Tanzania. 60 L&D providers participated in the MAMA training, which included a two-and-a-half-day workshop followed by a half-day on-site refresher. We assessed the impact of the MAMA training using a pre-post quasi-experimental design. To assess provider impacts, participants completed assessments at baseline and post-intervention periods, measuring RMC practices, HIV stigma, and self-efficacy to provide care. To evaluate patient impacts, we enrolled birthing women at the study facilities in the pre- (n = 229) and post- (n = 214) intervention periods and assessed self-reported RMC and perceptions of provider HIV stigma. We also collected facility-level data on the proportion of patients who gave birth by cesarean section, disaggregated by HIV status. The intervention had a positive impact on all provider outcomes; providers reported using more RMC practices, lower levels of HIV stigma, and greater self-efficacy to provide care for WLHIV. We did not observe differences in self-reported patient outcomes. In facility-level data, we observed a trend in reduction in cesarean section rates for WLHIV (33.0% vs. 24.1%, p = 0.14). The findings suggest that the MAMA training may improve providers' attitudes and practices in caring for WLHIV giving birth and should be considered for scale-up.

RESUMO

BACKGROUND: In northern Tanzania, Q fever, spotted fever group (SFG) rickettsioses, and typhus group (TG) rickettsioses are common causes of febrile illness. We sought to describe the prevalence and risk factors for these zoonoses in a pastoralist community. METHODS: Febrile patients ≥2 years old presenting to Endulen Hospital in the Ngorongoro Conservation Area were enrolled from August 2016 through October 2017. Acute and convalescent blood samples were collected, and a questionnaire was administered. Sera were tested by immunofluorescent antibody (IFA) IgG assays using Coxiella burnetii (Phase II), Rickettsia africae, and Rickettsia typhi antigens. Serologic evidence of exposure was defined by an IFA titre ≥1:64; probable cases by an acute IFA titre ≥1:128; and confirmed cases by a ≥4-fold rise in titre between samples. Risk factors for exposure and acute case status were evaluated. RESULTS: Of 228 participants, 99 (43.4%) were male and the median (interquartile range) age was 27 (16-41) years. Among these, 117 (51.3%) had C. burnetii exposure, 74 (32.5%) had probable Q fever, 176 (77.2%) had SFG Rickettsia exposure, 134 (58.8%) had probable SFG rickettsioses, 11 (4.8%) had TG Rickettsia exposure, and 4 (1.8%) had probable TG rickettsioses. Of 146 participants with paired sera, 1 (0.5%) had confirmed Q fever, 8 (5.5%) had confirmed SFG rickettsioses, and none had confirmed TG rickettsioses. Livestock slaughter was associated with acute Q fever (adjusted odds ratio [OR] 2.54, 95% confidence interval [CI] 1.38-4.76) and sheep slaughter with SFG rickettsioses case (OR 4.63, 95% CI 1.08-23.50). DISCUSSION: Acute Q fever and SFG rickettsioses were detected in participants with febrile illness. Exposures to C. burnetii and to SFG Rickettsia were highly prevalent, and interactions with livestock were associated with increased odds of illness with both pathogens. Further characterisation of the burden and risks for these diseases is warranted.

RESUMO

Women living with HIV (WLHIV) commonly experience HIV-related shame which can interfere with HIV care-seeking behavior and lead to poor clinical outcomes. HIV-related shame may be particularly heightened during the pregnancy and postpartum periods. This study aimed to describe HIV-related shame among WLHIV giving birth, identify associated factors, and qualitatively examine the impacts of HIV-related shame on the childbirth experience. Postpartum WLHIV (n = 103) were enrolled in the study between March and July 2022 at six clinics in the Kilimanjaro Region, Tanzania. Participants completed a survey within 48 h after birth, prior to being discharged. The survey included a 13-item measure of HIV-related shame, which assessed levels of HIV-related shame (Range: 0-52). Univariable and multivariable regression models examined factors associated with HIV-related shame. Qualitative in-depth interviews were conducted with pregnant WLHIV (n = 12) and postpartum WLHIV (n = 12). Thematic analysis, including memo writing, coding, and synthesis, was employed to analyze the qualitative data. The survey sample had a mean age of 29.1 (SD = 5.7), and 52% were diagnosed with HIV during the current pregnancy. Nearly all participants (98%) endorsed at least one item reflecting HIV-related shame, with an average endorsement of 9 items (IQR = 6). In the final multivariable model, HIV-related shame was significantly associated with being Muslim vs. Christian (ß = 6.80; 95%CI: 1.51, 12.09), attending less than four antenatal care appointments (ß = 5.30; 95%CI: 0.04, 10.55), and reporting experiences of HIV stigma in the health system (ß = 0.69; 95%CI: 0.27, 1.12). Qualitative discussions revealed three key themes regarding the impact of HIV-related shame on the childbirth experience: reluctance to disclose HIV status, suboptimal adherence to care, and the influence on social support networks. WLHIV giving birth experience high rates of HIV-related shame, and social determinants may contribute to feelings of shame. HIV-related shame impacts the childbirth experience for WLHIV, making the labor and delivery setting an important site for intervention and support.The study is funded by the National Institutes of Health (R21 TW012001) and is registered on clinicaltrials.gov (NCT05271903).

RESUMO

OBJECTIVE: Male engagement in pregnancy care can be beneficial for maternal and child health outcomes. In Tanzania, pregnant women are strongly encouraged to present to their first antenatal care (ANC) appointment with a male partner, where they jointly test for HIV. For some, this presents a barrier to ANC attendance. The objectives of this study were to identify factors associated with presenting to ANC with a male partner using a cross-sectional design and to assess whether women presenting without partners had significantly delayed presentation. METHODS: Pregnant women (n = 1007) attending a first ANC appointment in Moshi, Tanzania were surveyed. Questions captured sociodemographic characteristics and measures of psychosocial constructs. RESULTS: Just over half (54%) of women presented to care with a male partner. Women were more likely to present with a male partner if they were younger than 25 years old, married, Muslim, attending ANC for their first pregnancy, and testing for HIV for the first time. Women presenting to ANC with a male partner were significantly more likely to attend ANC earlier in their pregnancy than those presenting without male partners. CONCLUSION: Policy change allowing women to present to care with other supportive family members could promote earlier presentation to first ANC. Unmarried women may be at a disadvantage in presenting to ANC when policies mandate attendance with a male partner. Male partners of multiparous women should be encouraged to provide pregnancy support even after first pregnancies, and a wholistic emphasis (beyond HIV testing) on first ANC could encourage male engagement beyond the initial appointment.

RESUMO

We conducted a cross-sectional study of Crimean-Congo hemorrhagic fever virus (CCHFV) in northern Tanzania. CCHFV seroprevalence in humans and ruminant livestock was high, as were spatial heterogeneity levels. CCHFV could represent an unrecognized human health risk in this region and should be included as a differential diagnosis for febrile illness.

RESUMO

BACKGROUND: Antimicrobial resistance (AMR) of Neisseria gonorrhoeae is a threat to public health as strains have developed resistance to antimicrobials available for the treatment of gonorrhea. Whole genome sequencing (WGS) can detect and predict antimicrobial resistance to enhance the control and prevention of gonorrhea. Data on the molecular epidemiology of N. gonorrhoeae is sparse in Zambia. This study aimed to determine the genetic diversity of N. gonorrhoeae isolated from patients attending sexually transmitted infection (STI) clinics in Lusaka, Zambia. METHODS: A cross-sectional study that sequenced 38 N. gonorrhoeae isolated from 122 patients with gonorrhea from 2019 to 2020 was conducted. The AMR profiles were determined by the E-test, and the DNA was extracted using the NucliSens easyMaG magnetic device. Whole genome sequencing was performed on the Illumina NextSeq550 platform. The Bacterial analysis pipeline (BAP) that is readily available at: https://cge.cbs.dtu.dk/services/CGEpipeline-1.1 was used for the identification of the species, assembling the genome, multi-locus sequence typing (MLST), detection of plasmids and AMR genes. Phylogeny by single nucleotide polymorphisms (SNPs) was determined with the CCphylo dataset. RESULTS: The most frequent STs with 18.4% of isolates each were ST7363, ST1921 and ST1582, followed by ST1583 (13%), novel ST17026 (7.9%), ST1588 (7.9%), ST1596 (5.3%), ST11181 (5.3%), ST11750 (2.6/%) and ST11241 (2.6%) among the 38 genotyped isolates. The blaTeM-1B and tetM (55%) was the most prevalent combination of AMR genes, followed by blaTeM-1B (18.4%), tetM (15.8%), and the combination of blaTeM-1B, ermT, and tetL was 2.6% of the isolates. The AMR phenotypes were predicted in ciprofloxacin, penicillin, tetracycline, azithromycin, and cefixime. The combination of mutations 23.7% was gryA (S91F), parC (E91G), ponA (L421) and rpsJ (V57M), followed by 18.4% in gyrA (S91F), ponA (L421P), rpsJ (V57M), and 18.4% in gyrA (D95G, S91F), ponA (L421P), and rpsJ (V57M). The combinations in gyrA (D95G, S91F) and rpsJ (V57M), and gyrA (D95G, S91F), parC (E91F), ponA (L421P) and rpsJ (V57M) were 13.2% each of the isolates. Plasmid TEM-1 (84.2%), tetM (15.8%), and gonococcal genetic island (GGI) was detected in all isolates. CONCLUSION: This study revealed remarkable heterogeneity of N. gonorrhoeae with blaTEM-1, tetM, ponA, gyrA, and parC genes associated with high resistance to penicillin, tetracycline, and ciprofloxacin demanding revision of the standard treatment guidelines and improved antimicrobial stewardship in Zambia.

RESUMO

Alcohol's ever-increasing global use poses a distinct threat to human well-being, with intake and associated burdens rising especially quickly in low- and middle-income countries like Tanzania. Prior research has shown alcohol use and related consequences differ by gender in Moshi, Tanzania, with important implications for both clinical care and future alcohol-reduction interventions. This study builds upon this knowledge by providing a deeper understanding of how gender differences affect alcohol-related stigma and sexual assault among Emergency Department (ED) and Reproductive Health Center (RHC) patients at Kilimanjaro Christian Medical Center (KCMC) in Moshi. In-depth interviews were conducted among ED and RHC KCMC patients (n = 19) selected for participation via purposive sampling. A mix of inductive and deductive coding schemes was used to identify themes and subthemes. All data were analyzed through a grounded theory approach. Gender roles that linked men with financial responsibilities and women with child caretaking led to different expectations on alcohol intake, with alcohol use encouraged for men but vilified for women. Women who drank, for example, were deemed poor mothers and undesirable spouses. Patients likewise emphasized that both alcohol-related stigma and sexual violence disproportionately impacted women, the latter fueled through alcohol use, with serious and lasting acts of discrimination and isolation from community members seen among women alcohol users but not for men. Women alcohol users in Moshi are subject to severe social consequences, facing disproportionate stigma and sexual violence as compared to men. Alcohol-related treatment for women should be mindful of the disproportionate burdens present in this context while treatment for men should be cognizant of the social pressures to drink. Strategies to address and/or mitigate these factors should be incorporated in subsequent care and interventions.

RESUMO

Large-scale biorepositories and databases are essential to generate equitable, effective, and sustainable advances in cancer prevention, early detection, cancer therapy, cancer care, and surveillance. The Mutographs project has created a large genomic dataset and biorepository of over 7,800 cancer cases from 30 countries across five continents with extensive demographic, lifestyle, environmental, and clinical information. Whole-genome sequencing is being finalized for over 4,000 cases, with the primary goal of understanding the causes of cancer at eight anatomic sites. Genomic, exposure, and clinical data will be publicly available through the International Cancer Genome Consortium Accelerating Research in Genomic Oncology platform. The Mutographs sample and metadata biorepository constitutes a legacy resource for new projects and collaborations aiming to increase our current research efforts in cancer genomic epidemiology globally.

RESUMO

BACKGROUND: In Ethiopia, both incidence and mortality of cervical cancer are relatively high. Screening services, which were implemented during the past few years, are currently being expanded. The World Health Organization recommends patients with a positive VIA (visual inspection with acetic acid) result should immediately receive treatment followed by rescreening after 1 year as precancerous lesions can reoccur or become residential despite treatment. MATERIALS AND METHODS: Screening logbooks dating between 2017 and 2020 were retrospectively reviewed in 14 health facilities of Addis Ababa and Oromia region. Data for 741 women with a VIA-positive result were extracted and those women were asked to participate in a questionnaire-based phone interview to gain insights about adherence to treatment and follow-up. Data were analyzed using descriptive methods and then fitted into 2 generalized linear models to test variables for an influence on adherence to follow up. RESULTS: Around 13 800 women had received a VIA screening, of which approximately 820 (5.9%) were VIA positive. While over 90% of women with a positive screen received treatment, only about half of the treated patients returned for a follow-up examination. After treatment, 31 women had a VIA-positive re-screen. We found that educational status, age over 40, no/incorrect follow-up appointment, health facility-related barriers, and use of reminders are important drivers of adherence to follow up. CONCLUSION: Our results revealed that adherence to treatment after VIA positive screening is relatively high whereas adherence to follow up recommendations still needs improvement. Reminders like appointment cards and phone calls can effectively reduce the loss of follow-up.

RESUMO

People living with HIV (PLWH) experience unique stressors that contribute to emotional distress, and PLWH are more than twice as likely to die by suicide when compared to the general population. In countries like Tanzania, there is a relatively high burden of HIV but few resources to support mental health needs. To gain a better understanding of mental health challenges experienced by PLWH in northern Tanzania and identify opportunities for intervention, we interviewed 12 mental health professionals working in the Kilimanjaro region. Thematic analysis was used to explore drivers and impacts of emotional distress, community influences on mental health, and gaps and barriers to existing mental health care. Perspectives from mental health workers highlight the compounding effects of stress related to HIV status, family conflict, finances, and other social challenges, which can lead to poor HIV treatment outcomes and suicidal ideation. Cultural beliefs and stigma surrounding both mental health and HIV limit care-seeking behavior for mental health issues. Those who do seek care often encounter barriers related to poor mental health infrastructure, including a lack of providers, limited financial resources, and little integration into other health services. There is a clear need for investment in the mental health care system, as well as interventions to improve knowledge and perceptions of mental health and comprehensively address stressors. We describe feedback on a proposed telehealth counseling intervention integrated into routine HIV services, which shows strong potential to mitigate barriers to mental health treatment, reduce suicidal ideation, and support the wellbeing of PLWH.

RESUMO

Antibacterial resistance (ABR) is a major public health threat. An important accelerating factor is treatment-seeking behaviour, including inappropriate antibiotic (AB) use. In many low- and middle-income countries (LMICs) this includes taking ABs with and without prescription sourced from various providers, including health facilities and community drug sellers. However, investigations of complex treatment-seeking, AB use and drug resistance in LMICs are scarce. The Holistic Approach to Unravel Antibacterial Resistance in East Africa (HATUA) Consortium collected questionnaire and microbiological data from adult outpatients with urinary tract infection (UTI)-like symptoms presenting at healthcare facilities in Kenya, Tanzania and Uganda. Using data from 6,388 patients, we analysed patterns of self-reported treatment seeking behaviours ('patient pathways') using process mining and single-channel sequence analysis. Among those with microbiologically confirmed UTI (n = 1,946), we used logistic regression to assess the relationship between treatment seeking behaviour, AB use, and the likelihood of having a multi-drug resistant (MDR) UTI. The most common treatment pathway for UTI-like symptoms in this sample involved attending health facilities, rather than other providers like drug sellers. Patients from sites in Tanzania and Uganda, where over 50% of patients had an MDR UTI, were more likely to report treatment failures, and have repeat visits to providers than those from Kenyan sites, where MDR UTI proportions were lower (33%). There was no strong or consistent relationship between individual AB use and likelihood of MDR UTI, after accounting for country context. The results highlight the hurdles East African patients face in accessing effective UTI care. These challenges are exacerbated by high rates of MDR UTI, suggesting a vicious cycle of failed treatment attempts and sustained selection for drug resistance. Whilst individual AB use may contribute to the risk of MDR UTI, our data show that factors related to context are stronger drivers of variations in ABR.

RESUMO

Climate change is not just jeopardizing the health of our planet but is also increasingly affecting our immune health. There is an expanding body of evidence that climate-related exposures such as air pollution, heat, wildfires, extreme weather events, and biodiversity loss significantly disrupt the functioning of the human immune system. These exposures manifest in a broad range of stimuli, including antigens, allergens, heat stress, pollutants, microbiota changes, and other toxic substances. Such exposures pose a direct and indirect threat to our body's primary line of defense, the epithelial barrier, affecting its physical integrity and functional efficacy. Furthermore, these climate-related environmental stressors can hyperstimulate the innate immune system and influence adaptive immunity-notably, in terms of developing and preserving immune tolerance. The loss or failure of immune tolerance can instigate a wide spectrum of noncommunicable diseases such as autoimmune conditions, allergy, respiratory illnesses, metabolic diseases, obesity, and others. As new evidence unfolds, there is a need for additional research in climate change and immunology that covers diverse environments in different global settings and uses modern biologic and epidemiologic tools.

RESUMO

INTRODUCTION: Musculoskeletal disorders, experienced as joint pain, are a significant global health problem, but little is known about how joint pain is categorised and understood in Tanzania. Understanding existing conceptualisations of and responses to joint pain is important to ensure both research and interventions are equitable and avoid biomedical imposition. METHODS: Rapid ethnographic appraisal was conducted in a periurban and rural community in Kilimanjaro, documenting language used to describe joint pain, ideas about causes, understandings of who experiences such pain, the impacts pain has and how people respond to it. We conducted 66 interviews with community leaders, traditional healers, community members and pharmacists.Photographs were taken and included in fieldnotes to supplement the interview data and develop thick descriptions. Data were analysed by constant comparison using QDA Miner software. RESULTS: Across the sample, dominant concepts of joint pain were named ugonjwa wa baridi, cold disease; ugonjwa wa uzee, old age disease; rimatizim, disease of the joints; and gauti, gout. Causes mentioned included exposure to the cold, old age, alcohol and red meat consumption, witchcraft, demons and injuries/falls. Age, gender and occupation were seen as important factors for developing joint pain. Perceived impacts of joint pain included loss of mobility, economic and family problems, developing new health conditions, death, reduction in sexual functioning and negative self-perceptions. Responses to joint pain blended biomedical treatments, herbal remedies, consultations with traditional healers and religious rituals. CONCLUSIONS: Conceptualisations of and responses to joint pain in the two communities were syncretic, mixing folk and biomedical practices. Narratives about who is affected by joint pain mirror emerging epidemiological findings, suggesting a strong 'lay epidemiology' in these communities. Anthropological methods can support the decolonisation of global health by decentring the imposition of English language biomedicine and pursuing synthetic, dignified languages of care.
