Adverse childhood experiences and intimate partner violence during pregnancy and their association to postpartum depression.
Get PDFBACKGROUND: Adverse childhood experiences (ACEs) and intimate partner violence (IPV) are recognized global health problems. Both ACEs and IPV have been linked to adverse physical and mental health problems for both mothers and infants. The aim of this study was to determine the prevalence of physical and/or sexual ACEs and IPV and their association to symptoms of postpartum depression among postpartum women in sub-Saharan Africa. METHODS: A cross-sectional survey was conducted in three health centers in the three districts of Dar es Salaam, comprising Ilala, Kinondoni and Temeke. A total of 500 women were interviewed by two trained midwife nurses during their routine postnatal care. The women were asked about their experiences of adverse childhood experiences, intimate partner violence and symptoms of postpartum depression. RESULTS: Of the 500 women who were interviewed, 39.4% (n = 197) reported to have experienced physical and/or sexual ACE and 18.8% (n = 94) experienced physical and/or sexual IPV during their index pregnancy. Physical ACE (AOR 2.6, 95% CI: 1.50-4.57), sexual ACE (AOR 2.7, 95% CI: 1.35-5.41), physical IPV (AOR 5.8, 95% CI: 2.98-11.43) and Sexual IPV (AOR 5.5, 95%CI: 2.51, 12.09) were significantly associated with symptoms of postpartum depression. CONCLUSION: Four out of ten women reported to have experienced ACEs and two out of ten women reported IPV in the index pregnancy which was significantly associated with symptoms of postpartum depression. These results are alarming and call upon the attention of health workers and the community at large in prevention, screening and early intervention of ACEs, IPV and symptoms of postpartum depression

We use Cox proportional hazard models to assess the time-varying association of multivitamin supplementation with mortality and clinical outcomes.Results:The study cohort contributed 41,540 and 129,315 person-years of follow-up time to the ART-na\uefve and ART-experienced analyses, respectively. Among 48,207 ART-na\uefve adults, provision of multivitamins reduced the risk of mortality (adjusted hazard ratio (aHR): 0.69; 95% CI: 0.59\u20130.81), incident tuberculosis (TB) (aHR: 0.83; 0.76\u20130.91), and meeting ART eligibility criteria (aHR: 0.78; 95% CI: 0.73\u20130.83) after adjustment for time-varying confounding. Among 46,977 ART-experienced patients, multivitamins reduced mortality (HR: 0.86; 95% CI: 0.80\u20130.92), incident TB (aHR: 0.78; 95% CI: 0.73\u20130.84), and immunologic failure (aHR: 0.70; 95% CI: 0.67\u20130.73). The survival benefits associated with provision multivitamins appeared to be greatest during the first year of ART and declined over time (p-value <0.001).Conclusion:Multivitamin supplementation appears to be a simple, effective, safe, and scalable program to improve survival, reduce incidence of TB, and improve treatment outcomes for adult HIV patients in Tanzania.20192020-01-27T00:00:00ZD43 TW009775/TW/FIC NIH HHS/United StatesU2G PS001966/PS/NCHHSTP CDC HHS/United StatesPEPFAR/PEPFAR/United States30289815PMC6599688712
Health services we can trust: how same-sex attracted men in Dar Es Salaam, Tanzania would like their HIV healthcare to be organised
No full textDrawing on qualitative research in Dar es Salaam, Tanzania, this article explores how men who engage in sex with other men perceive their interactions with healthcare providers, and how they would prefer healthcare services to be organised and delivered. The paper describes the strengths and weaknesses men associate with private and public healthcare; the advantages and disadvantages they associate with dedicated clinics for sexual minority persons; what they conceive of as good healthcare services; and how they would characterise a good healthcare worker. The paper also presents recommendations made by study participants. These include the view that health services for same-sex attracted men should be developed and delivered in collaboration with such men themselves; that health workers should receive training on the medical needs as well as the overall circumstances of same-sex attracted men; and that there should be mechanisms that make healthcare available to poorer community members. We analyse men’s views and recommendations in the light of theoretical work on trust and discuss the ways in which same sex attracted men look for signs that healthcare workers and healthcare services are trustworthy
Immunoglobulin G responses against falciparum malaria specific antigens are higher in children with homozygous sickle cell trait than those with normal hemoglobin
No full textAbstract Background High Immunoglobulin G (IgG) response to Plasmodium falciparum antigens is associated with partial malaria protection in sickle hemoglobin (HbS) children. However, this response has been more studied in children with heterozygous sickle cell trait (HbAS) but little explored in those with homozygous sickle cell trait (HbSS). The current study was conducted to determine the IgG responses against specific Plasmodium falciparum antigens in children with homozygous sickle cell trait (HbSS) by comparing to those with normal hemoglobin (HbAA). Methods A cross sectional study was conducted between April and July 2018 in Dar es Salaam tertiary hospitals. Parents were consented for their child to give about 5 ml of venous blood. IgG concentration from the blood plasma of 220 children (110 HbAA vs. 110 HbSS) were determined using indirect Enzyme Linked Immunosorbent Assay (ELISA). Then IgG medians were compared between the groups with prism 5 software (GraphPad) using Mann Whitney U test. Where the differences in age, hemoglobin levels and body weight between the groups was analyzed using independent sample t test. Multiple linear regressions were used to control cofounding variables such as body weight, age and hemoglobin level using statistical package for social sciences software (SPSS version 23). P value <0.05 was considered statistically significant. Results The median IgG concentration to PfEBA-175, Pfg27, yPfs28C antigens were HbSS; 20.7 ng/ml (IQR; 18.1–25.6) vs. HbAA; 2.3 ng/ml (IQR; 1.21–3.04), HbSS; 2.76 ng/ml (IQR: 2.08–5.69) vs. HbAA; 1.36 ng/ml (IQR: 1.28–1.76), and HbSS; 26,592 ng/ml (IQR: 10817–41,462) vs. HbAA; 14,164 ng/ml (IQR; 3069–24,302) respectively (p < 0.0001 for all IgG). In both groups; age, body weight and hemoglobin level had no impact on the levels of IgG responses to Plasmodium falciparum antigens except for HbAA group which showed a significant increase in IgG against Pfg27 by 0.004 ng/ml with 1 g/dl increase in Hb level (p = 0.028). Conclusions This study found significant higher levels of specific Plasmodium falciparum IgG responses in children with homozygous sickle cell trait than those with normal hemoglobin
HIV/HCV co-infection and associated risk factors among injecting drug users in Dar es Salaam, Tanzania: potential for HCV elimination
No full textBackground
Chronic HCV infection causes substantial morbidity and mortality and, in co-infection with HIV, may result in immunological and virological failure following antiretroviral treatment. Estimates of HCV infection, co-infection with HIV and associated risk practices among PWID are scarce in Africa. This study therefore aimed at estimating the prevalence of HCV and associated risk factors among PWID in the largest metropolitan city in Tanzania to inform WHO elimination recommendations.
Methods
An integrated bio-behavioral survey using respondent-driven sampling was used to recruit PWID residing in Dar es Salaam, Tanzania. Following face-to-face interviews, blood samples were collected for HIV and HCV testing. Weighted modified Poisson regression modeling with robust standard errors was used in the analysis.
Results
A total of 611 PWID with a median age of 34 years (IQR, 29–38) were recruited through 4 to 8 waves. The majority of participants (94.3%) were males, and the median age at first injection was 24 years (IQR, 19–30). Only 6.55% (40/611) of participants reported to have been enrolled in opioid treatment programs. The weighted HCV antibody prevalence was 16.2% (95%CI, 13.0–20.1). The corresponding prevalence of HIV infection was 8.7% (95%CI, 6.4–11.8). Of the 51 PWID who were infected with HIV, 22 (43.1%) were HCV seropositive. Lack of access to clean needles (adjusted prevalence ratio (APR), 1.76; 95%CI, 1.44; 12.74), sharing a needle the past month (APR, 1.72; 95%CI, 1.02; 3.00), not cleaning the needle the last time shared (APR, 2.29; 95%CI, 1.00; 6.37), and having unprotected not using a transactional sex (APR, 1.87; 95%CI, 1.00; 3.61) were associated with increased risk of HCV infection. On the other hand, not being on opioid substitution therapy was associated with 60% lower likelihood of infection.
Conclusions
The HCV antibody prevalence among PWID is lower than global estimates indicating potential for elimination. Improving access to safe injecting paraphernalia, promoting safer injecting practices is the focus of prevention programing. Screening for HIV/HCV co-infection should be intensified in HIV care, opioid substitution programs, and other point of care for PWID. Use of direct-acting antiretroviral treatment would accelerate the achievement of hepatitis infection elimination goal by 2030

HIV prevalence among men who have sex with men following the implementation of the HIV preventive guideline in Tanzania:respondent-driven sampling survey
No full textObjectives To estimate HIV prevalence and associated risk factors among men who have sex with men (MSM) in Dar es Salaam, Tanzania following the implementation of the national comprehensive package of HIV interventions for key population (CHIP). Design A cross-sectional survey using respondent-driven sampling. Setting Dar es Salaam, Tanzania's largest city. Participants Men who occasionally or regularly have sex with another man, aged 18 years and above and living in Dar es Salaam city at least 6 months preceding the study. Primary outcome measure HIV prevalence was the primary outcome. Independent risk factors for HIV infection were examined using weighted logistics regression modelling. Results A total of 777 MSM with a mean age of 26 years took part in the study. The weighted HIV prevalence was 8.3% (95% CI: 6.3%-10.9%) as compared with 22.3% (95% CI: 18.7%-26.4%) observed in a similar survey in 2014. Half of the participants had had sex with more than two partners in the month preceding the survey. Among those who had engaged in transactional sex, 80% had used a condom during last anal sex with a paying partner. Participants aged 25 and above had four times higher odds of being infected than those aged 15-19 years. HIV infection was associated with multiple sexual partnerships (adjusted OR/AOR, 3.0; 95% CI: 1.8-12.0), not having used condom during last sex with non-paying partner (AOR, 4.1; 95% CI: 1.4-7.8) and ever having engaged in group sex (AOR, 3.4; 95% CI: 1.7-3.6). Conclusion HIV prevalence among MSM in Dar es Salaam has decreased by more than a half over the past 5 years, coinciding with implementation of the CHIP. It is nonetheless two times as high as that of men in the general population. To achieve the 2030 goal, behavioural change interventions and roll out of new intervention measures such as pre-exposure prophylaxis are urgently needed.</p
A Retrospective Study of Patients with Castrate Resistant Prostate Cancer at Muhimbili National Hospital, Tanzania
No full textBackground: Prostate cancer (PC) is a common health problem among men globally with high incidence and mortality. The mortality following PC is associated with advanced disease progressing to castrate resistance following androgen ablation therapies. While advances to addresscastrate resistant prostatic cancer (CRPC) have shown good results, the burden of castrate resistant cancer in Tanzania has remained unknown hence our patients cannot benefit from such advances. This study therefore aimed to determine the magnitude and clinical presentation among patients with a diagnosis of castrate resistant cancer at Muhimbili National Hospital in 2018-2019.
Methods: This was a retrospective descriptive hospital based study carried out at Muhimbili National Hospital. Patients who were treated with androgen blockade, had evidence of attainment of castrate levels of testosterone with a diagnosis of castrate resistant prostate cancer were identified. Information regarding primary prostatic cancer treatment, clinical disease progression symptoms, and age of the patients were collected. Descriptive statistics were prepared and summarized as tables and figures.
Results: We recruited 293 patients with prostate cancer treated by androgen deprivation therapy. Bilateral orchiectomy was the most common treatment modality offered for advanced PC. Castrate levels of testosterone were achieved in 189 (95.5%) of the patients who had testosterone levels checked. Ninety-Six (50.8%) had met the criteria for diagnosis of castrate resistant prostate cancer with mean age of 71.23±4.2 years. Patients presented with lower urinary tract symptoms and metastatic features. Most of the patients had a poorly differentiated histology with prostate specific antigen (PSA) over 100ng/l. Only 13.5% of the patients had spine magnetic resonance imaging (MRI) for their work up.
Conclusion and recommendation: Half of patients treated for advanced PC at MNH will progress to castrate resistance following androgen deprivation therapy. More studies are needed to understand the predictors of CRPC and related treatment strategies.
