RESUMEN

There is limited district level data on drug or alcohol use as well as sex and reproductive history among secondary school students in Tanzania to inform prevention efforts. To address this, we conducted a survey of 2523 secondary school students in 2 districts (Bahi and Mpwapwa) and the Dodoma municipal area in Tanzania. Overall, fifty three percent were female and 67% were between the ages of 15 and 17 years old. Students in the Dodoma Municipality district self-reported the highest prevalence of forced sex, sex for gifts or money, and drug use. Students in the Bahi district reported the highest prevalence of alcohol use. Males reported a higher prevalence of consensual sex, contraception use, and alcohol and drug use compared to females, the latter of whom reported a higher prevalence of forced sex. Most students' indicated that their primary source of sex and reproductive health information was their teachers. These results suggest the need for tailored interventions among secondary school students in the Dodoma region in Tanzania.

RESUMEN

BACKGROUND: Unacceptably high levels of maternal deaths still occur in many sub-Saharan countries and the health systems may not favour effective use of lessons from maternal death reviews to improve maternal survival. We report results from the analysis of data from maternal death reviews at Bugando Medical Centre north-western Tanzania in the period 2008-2012 and highlight the process, challenges and how the analysis provided a better understanding of maternal deaths. METHODOLOGY: Retrospective analysis using maternal death review data and extraction of missing information from patients' files. Analysis was done in STATA statistical package into frequencies and means ± SD and median with 95% CI for categorical and numerical data respectively. RESULTS: There were 80 deaths; mean age of the deceased 27.1 ± 6.2 years and a median hospital stay of 11.0 days [95% CI 11.0-15.3]. Most deaths were from direct obstetric causes (90); 60% from eclampsia, severe pre-eclampsia, sepsis, abortion and anaesthetic complications. Information on ANC attendance was recorded in 36.2% of the forms and gestation age of the pregnancy resulting into the death in 23.8%. Sixty one deaths (76.3%) occurred after delivery. The mode of delivery, place of delivery and delivery assistant were recorded in 44 (72.1), 38 (62.3) and 23 (37.7%) respectively. CONCLUSION: Routine maternal death reviews in this setting do not involve comprehensive documentation of all relevant information, including actions taken to address some identified systemic weaknesses. Periodic analysis of available data may allow better understanding of vital information to improve the quality of maternity care.

RESUMEN

BACKGROUND: Sero-positivity rates of the rubella virus among pregnant women vary widely throughout the world. In Tanzania, rubella vaccination is not included in the national immunization schedule and there is therefore no antenatal screening for this viral disease. So far, there are no reports on the sero-prevalence of rubella among pregnant women in Tanzania. As a result, this study was undertaken to establish the sero-positivity rate of rubella and rubella risk factors among pregnant women attending antenatal care clinics in Mwanza, Tanzania. METHODS: From November 2012 to May 2013 a total of 350 pregnant women were enrolled and their serum samples collected and analyzed using the AXSYM anti-rubella virus IgG/IgM-MEIA test. Demographic and clinical data were collected using a standardized data collection tool. Data analysis was done using STATA version 12. RESULTS: Of 342 pregnant women tested for rubella antibodies, 317 (92.6%) were positive for anti-rubella IgG while only 1 (0.3%) was positive for IgM. Higher sero-positivity rates were found in the age group of 25-44 years. Furthermore, it was observed that with each year increase in age, the risk of contracting rubella increases by 12% (OR = 1.12, 95% CI: 1.02-1.22, P = 0.019). Women involved in farming and business women were at a higher risk of contracting rubella infection compared to formally employed women (OR: 4.9, P = 0.011; OR 7.1, p = 0.003 respectively). In univariate analysis, the risk of contracting rubella virus infection was found to increase with gestational age with a statistical significance. CONCLUSIONS: Sero-positivity rates of rubella are high in Mwanza and are significantly associated with an increase in age and being a farmer or a business woman. Screening of rubella and immunization of women at risk are highly recommended in this area with a high non-immune rate against rubella virus.

RESUMEN

Background: The burden of infertility is serious for women in high-fertility countries. Objectives: We sought to identify demographic, behavioral/environmental, and reproductive risk factors for various infertility factors (i.e., ovarian, tubal, uterine/cervical, male/other) among women seeking infertility treatment in central Tanzania; to determine the association between pelvic inflammatory disease (PID) and tubal factor infertility (TFI); and to identify barriers to infertility treatment by women's home regional zone. Methods: We conducted a cross-sectional survey of women seeking infertility treatment in Dodoma, Tanzania from January-March 2020. We surveyed 168 participants aged 18-49 years and reviewed their medical records to confirm infertility status and potential risk factors. We estimated prevalence ratios for factors associated with infertility using logistic regression. Treatment barriers were compared by women's regional zone to see if barriers varied geographically. Results: The median age of participants was 32 years (range: 18-48). Infertility factors did not vary greatly by patient demographics, behavioral/environmental, or reproductive risk factors. Approximately 31.48% of women had PID diagnoses. Those with PID had 1.94 (95% CI: 1.30, 2.90) times the prevalence of TFI diagnosis as those with other infertility factors, after adjusting for age, pesticide use, alcohol use, age at sexual debut, prior obstetric events, and family history of infertility. Logistical barriers to treatment, such as time and cost, were more frequently reported than emotional, stigma, or other barriers, regardless of regional zone. Conclusions: PID was strongly associated with TFI after adjustment for confounders. Infertility treatment access due to cost remains a challenge in Tanzania.

RESUMEN

We surveyed 169 women seeking infertility treatment in Central Tanzania using an abbreviated version of the Fertility Problem Inventory (FPI) to measure infertility-related stress. We compared our FPI results to similar studies in another high fertility country (Ghana) and in three low fertility countries (the US, Canada, and Italy). Tanzanian women reported higher infertility-related stress than women in low-fertility countries but lower stress than Ghanaian women. Infertility-related stress is a serious concern for women in high-fertility countries, who experience greater pressure to have children. These findings underscore the need for increased access to infertility treatment and addressing community infertility norms.

RESUMEN

OBJECTIVES: To report the results of a pilot study for a service for cervical cancer screening and diagnosis in north-western Tanzania. METHODS: The pilot study was launched in 2012 after a community-level information campaign. Women aged 15-64 years were encouraged to attend the district health centres. Attendees were offered a conventional Pap smear and a visual inspection of the cervix with acetic acid (VIA). RESULTS: The first 2500 women were evaluated. A total of 164 women (detection rate 70.0/1000) were diagnosed with high-grade cervical intraepithelial neoplasia and invasive cervical cancer. The performance of VIA was comparable to that of Pap smear. The district of residence, a history of untreated sexually transmitted disease, an HIV-negative status (inverse association), and parity were independently associated with the detected prevalence of disease. The probability of invasive versus preinvasive disease was lower in HIV-positive women and in women practicing breast self-examination. CONCLUSIONS: The diagnostic procedure had an acceptable level of quality. Factors associated with the detected prevalence of disease will allow for a more targeted promotion of the service. Cervical screening should be coordinated with sexually transmitted disease and HIV infection control activities.

RESUMEN

As US residency programs are increasingly offering global health electives for their trainees, there is a growing call for these opportunities to include bidirectional exchanges-where residents from both the US and international partner institutions rotate at the other's site. Curricular, logistical, and funding challenges of hosting residents from an international site may be barriers to developing these programs. In this report, the authors describe an 8-year experience of a US institution hosting residents from a resource-limited international partner and provide a framework for others institutions to develop bidirectional exchanges. They also report the visiting international residents' perceptions of the impact of the exchange on their clinical practice, teaching, career paths, and their home institution.

RESUMEN

BACKGROUND: HIV-disease progression correlates with immune activation. Here we investigated whether corticosteroid treatment can attenuate HIV disease progression in antiretroviral-untreated patients. METHODS: Double-blind, placebo-controlled randomized clinical trial including 326 HIV-patients in a resource-limited setting in Tanzania (clinicaltrials.gov NCT01299948). Inclusion criteria were a CD4 count above 300 cells/µl, the absence of AIDS-defining symptoms and an ART-naïve therapy status. Study participants received 5 mg prednisolone per day or placebo for 2 years. Primary endpoint was time to progression to an AIDS-defining condition or to a CD4-count below 200 cells/µl. RESULTS: No significant change in progression towards the primary endpoint was observed in the intent-to-treat (ITT) analysis (19 cases with prednisolone versus 28 cases with placebo, p = 0.1407). In a per-protocol (PP)-analysis, 13 versus 24 study participants progressed to the primary study endpoint (p = 0.0741). Secondary endpoints: Prednisolone-treatment decreased immune activation (sCD14, suPAR, CD38/HLA-DR/CD8+) and increased CD4-counts (+77.42 ± 5.70 cells/µl compared to -37.42 ± 10.77 cells/µl under placebo, p < 0.0001). Treatment with prednisolone was associated with a 3.2-fold increase in HIV viral load (p < 0.0001). In a post-hoc analysis stratifying for sex, females treated with prednisolone progressed significantly slower to the primary study endpoint than females treated with placebo (ITT-analysis: 11 versus 21 cases, p = 0.0567; PP-analysis: 5 versus 18 cases, p = 0.0051): No changes in disease progression were observed in men. CONCLUSIONS: This study could not detect any significant effects of prednisolone on disease progression in antiretroviral-untreated HIV infection within the intent-to-treat population. However, significant effects were observed on CD4 counts, immune activation and HIV viral load. This study contributes to a better understanding of the role of immune activation in the pathogenesis of HIV infection. TRIAL REGISTRATION: ClinicalTrials.gov NCT01299948.

RESUMEN

OBJECTIVE: Hypertension is believed to be an increasingly common driver of the epidemic of noncommunicable diseases (NCDs) in sub-Saharan Africa, but prospective data are scarce. The objective of this prospective study was to determine the contribution of hypertension to deaths, admissions, and hospital days at a Tanzanian zonal hospital. METHODS: Between 2009 and 2011, diagnoses were recorded for all medical admissions together with age, sex, length of hospitalization and in-hospital mortality. RESULTS: Among 11045 consecutive admissions, NCDs accounted for nearly half of all deaths, admissions, and hospital days. Among NCDs, hypertension-related diseases were the most common and accounted for 314 (33.9%) of the total NCD deaths, 1611 (29.9%) of the NCD admissions, and 12837 (27.8%) NCD hospital days. Stroke (167 deaths) was the leading cause of hypertension-related death. Hypertension was the leading cause of death in patients over the age of 50 years and 57% of hypertension-related deaths occurred in patients less than 65 years old. CONCLUSION: NCDs account for half of all deaths, admissions and hospital days at our Tanzanian hospital and hypertension-related diseases were the most common NCD. Hypertension accounted for 34% of NCD deaths and 15% of all deaths. Hypertension was the second most common cause of death overall and the leading cause of death in patients more than 50 years old. More than half of hypertension-related deaths occurred before retirement age. These findings have important implications for public health and medical education in sub-Saharan Africa, wherein hypertension and related diseases have not traditionally been given a high priority.

RESUMEN

BACKGROUND: Serological screening of pregnant women for Toxoplasma gondii-specific antibodies is not practiced as an antenatal care in Tanzania; and there is a limited data about sero-prevalence of T. gondii infection in developing countries. We therefore conducted this study to determine the sero-prevalence and factors associated with T. gondii infection among pregnant women attending antenatal care clinics in Mwanza, Tanzania. METHODS: Between 1st November 2012 and 31st May 2013 a total of 350 pregnant women attending antenatal care clinics in Mwanza were enrolled and screened for IgG and IgM antibodies against T. gondii using the ELISA technique. RESULTS: Of 350 pregnant women, 108 (30.9%) were sero-positive for T. gondii-specific antibodies. The risk of contracting T. gondii infection increases by 7% with each yearly increase in a woman's age (OR=1.07, 95% CI: 1.02 - 1.11, p=0.002). The sero-positivity rate of T. gondii-specific antibodies was higher among pregnant women from the urban than those from rural communities (41.5% versus 22.0%); [OR=2.2, 95% CI; 1.4 - 3.7, p=0.001]. Likewise employed/business women were more likely to get T. gondii infection than peasants (40.0% versus 25.9%) [OR=1.9, 95% CI: 1.2 - 3.0, p=0.006]. CONCLUSIONS: Sero-prevalence of T. gondii-specific antibodies is high among pregnant women in Mwanza with a significant proportion of women at risk of contracting primary T. gondii infections. Screening of T. gondii infections during antenatal care should be considered in Tanzania as the main strategy to minimize congenital toxoplasmosis.

RESUMEN

BACKGROUND: The World Health Organization (WHO) has recommended guidelines for a HIV drug resistance (HIVDR) survey for resource-limited countries. Eligibility criteria for patients include age below 25 years in order to focus on the prevalence of transmitted HIVDR (tHIVDR) in newly-infected individuals. Most of the participating sites across Africa have so far reported tHIVDR prevalences of below 5%. In this study we investigated whether the rate of HIVDR in patients <25 years is representative for HIVDR in the rest of the therapy-naïve population. METHODS AND FINDINGS: HIVDR was determined in 88 sequentially enrolled ART-naïve patients from Mwanza, Tanzania (mean age 35.4 years). Twenty patients were aged <25 years and 68 patients were aged 25-63 years. The frequency of HIVDR in the study population was 14.8% (95%; CI 0.072-0.223) and independent of NVP-resistance induced by prevention of mother-to-child transmission programs. Patients >25 years had a significantly higher HIVDR frequency than younger patients (19.1%; 95% CI 0.095-0.28) versus 0%, P = 0.0344). In 2 out of the 16 patients with HIVDR we found traces of antiretrovirals (ARVs) in plasma. CONCLUSIONS: ART-naïve patients aged over 25 years exhibited significantly higher HIVDR than younger patients. Detection of traces of ARVs in individuals with HIVDR suggests that besides transmission, undisclosed misuse of ARVs may constitute a significant factor in the generation of the observed high HIVDR rate. The current WHO tHIVDR survey that is solely focused on the transmission of HIVDR and that excludes patients over 25 years of age may therefore result in substantial underestimation of the prevalence of HIVDR in the therapy-naïve population. Similar studies should be performed also in other areas to test whether the so far reported optimistic picture of low HIVDR prevalence in young individuals is really representative for the rest of the ART-naïve HIV-infected population.
