Risk factors associated with pre-term birth in Dar es Salaam, Tanzania: a case-control study

Background: Preterm birth remains one of the most serious problems in obstetrics care. Its aetiology is complex and multifactorial. This study was carried out to determine risk factors for preterm birth in Dar es Salaam City in Tanzania.Methods: This case-control study was conducted in three municipal hospitals namely, Amani, Mwananyamala and Temeke in Dar es Salaam. It involved 377 pairs of women with preterm birth (cases) and term birth (controls). Eligible women who agreed to participate and who signed the consent form completed a short interview regarding demographic and lifestyle factors, had their baby examined for maturity, and had their medical records abstracted. All cases and controls were interviewed face-to-face using a specially designed questionnaire. Multivariate logistic regression after controlling for potential confounders was used to measure the strength of associations between preterm birth and related factors.Results: Several significant risk factors associations with pre-term birth were multiple pregnancies (AOR = 8.6; 95%CI 4.5-16.5; p-value <0.001), untreated vaginal discharge (AOR = 5.2; 95%CI 1.1-24.4; p-value 0.034), public prenatal care (AOR = 2.1; 95%CI 1.1-4.1; p-value 0.017), untreated urinary tract infection (AOR = 2.7; 95%CI 1.2-6.1; p-value 0.016), complication during pregnancy (AOR = 2.7; 95%CI 1.3-5.3; p-value 0.004), cervical incompetence (AOR = 11.6; 95%CI 1.1-121.5; p-value 0.04), polyhydramnios (AOR = 8.3; 95%CI 1.7-40.2; p-value 0.008), and lack of antenatal visits  (AOR = 5.1; 95%CI 1.4-17.8; p-value 0.042).Conclusion: This study has identified several risk factors for preterm birth in the city of Dar es Salaam. It is important that planners design community-based interventions to address complications from preterm birth

Predictors of linkage to care following community-based HIV counseling and testing in rural Kenya

Despite innovations in HIV counseling and testing (HCT), important gaps remain in understanding linkage to care. We followed a cohort diagnosed with HIV through a community-based HCT campaign that trained persons living with HIV/AIDS (PLHA) as navigators. Individual, interpersonal, and institutional predictors of linkage were assessed using survival analysis of self-reported time to enrollment. Of 483 persons consenting to follow-up, 305 (63.2%) enrolled in HIV care within 3 months. Proportions linking to care were similar across sexes, barring a sub-sample of men aged 18–25 years who were highly unlikely to enroll. Men were more likely to enroll if they had disclosed to their spouse, and women if they had disclosed to family. Women who anticipated violence or relationship breakup were less likely to link to care. Enrolment rates were significantly higher among participants receiving a PLHA visit, suggesting that a navigator approach may improve linkage from community-based HCT campaigns.Vestergaard Frandse

PEG1/MEST and IGF2 DNA methylation in CIN and in cervical cancer

IntroductionAlthough most invasive cervical cancer (ICC) harbor 30years further strengthened these associations.ConclusionsWhile the small sample size limits inference, these findings show that altered DNA methylation at imprinted domains including IGF2/H19 and PEG1/MEST may mediate the association between HPV and ICC risk

PEG1/MEST and IGF2 DNA methylation in CIN and in cervical cancer

INTRODUCTION: Although most invasive cervical cancer (ICC) harbor <20 human papillomavirus (HPV) genotypes, use of HPV screening to predict ICC from HPV has low specificity, resulting in multiple and costly follow-up visits and overtreatment. We examined DNA methylation at regulatory regions of imprinted genes in relation to ICC and its precursor lesions to determine if methylation profiles are associated with progression of HPV-positive lesions to ICC. MATERIALS AND METHODS: We enrolled 148 controls, 38 CIN and 48 ICC cases at Kilimanjaro Christian Medical Centre from 2008 to 2009. HPV was genotyped by linear array and HIV-1 serostatus was tested by two rapid HIV tests. DNA methylation was measured by bisulfite pyrosequencing at regions regulating eight imprinted domains. Logistic regression models were used to estimate odd ratios. RESULTS: After adjusting for age, HPV infection, parity, hormonal contraceptive use, and HIV-1 serostatus, a 10 % decrease in methylation levels at an intragenic region of IGF2 was associated with higher risk of ICC (OR 2.00, 95 % CI 1.14–3.44) and cervical intraepithelial neoplasia (CIN) (OR 1.51, 95 % CI 1.00–2.50). Methylation levels at the H19 DMR and PEG1/MEST were also associated with ICC risk (OR 1.51, 95 % CI 0.90–2.53, and OR 1.44, 95 % CI 0.90–2.35, respectively). Restricting analyses to women >30 years further strengthened these associations. CONCLUSIONS: While the small sample size limits inference, these findings show that altered DNA methylation at imprinted domains including IGF2/H19 and PEG1/MEST may mediate the association between HPV and ICC risk

Occupational therapy synergy between Comprehensive Community Based Rehabilitation Tanzania and Heifer International to reduce poverty

Background: This article describes a partnership between a community-based rehabilitation organisation and a non-governmental organisation (NGO) in Tanzania. The partnership focused on income-generating (IG) activities to tackle the problems of poverty faced by families with a child with a disability (CWD). Objectives: The aim of this case study was to describe the partnership between Comprehensive Community Based Rehabilitation Tanzania in Moshi (CCBRT-Moshi), a non-governmental organisation, and families to create an income-generating business, namely raising goats. Method: This was a team approach between CCBRT-Moshi and Heifer International, an organisation that focuses on IG activities to create a synergy or partnership between community-based rehabilitation and IG activities. Results: This partnership between occupational therapy rehabilitation services at CCBRT-Moshi and the NGO resulted in strengthening the effectiveness of occupational therapy services and leaving a more lasting impact on the people they served within the community by helping to reduce poverty in addition to providing rehabilitation and prevention interventions. Conclusion: This collaboration was successful as it provided a means for families to generate income from raising goats. Although the results have not been empirically verified, observational and anecdotal evidence suggests that families with CWDs have better quality of life and ultimately improved health through this synergistic partnership

Prevalence and severity of cervical squamous intraepithelial lesion in a tertiary hospital in northern Tanzania

Cervical cancer is the second most common cancer in women worldwide and the leading cause of cancer deaths in Tanzanian women. Prevention of cervical cancer relies on the detection and treatment of Squamous Intraepithelial Lesion (SIL), a premalignant disease stage. Worldwide there are overwhelming reports associating SIL and HIV infection, however in Tanzania such reports are limited. A cross-sectional hospital-based descriptive study was conducted to determine the prevalence and severity of SIL in 234 HIV seropositive and seronegative women aged 18-68 years old at Kilimanjaro Christian Medical Centre in northern Tanzania. A structured questionnaire was used to collect sociodemographic data. In addition, blood was collected for rapid HIV antibody testing and CD4+ T-lymphocyte counts to associate with prevalence and severity of SIL from the cervical smear collections. A total of 214 subjects had smear results regarded as valid for interpretation, of which 46.3% were HIV seropositive. Overall rate of SIL was 17%. Proportion of SIL among HIV seropositive subjects was 32% versus 4% in seronegative subjects (OR=13.3, 95% CI=4.2-46.4). Low CD4+ Tlymphocyte cell count was associated with higher prevalence of SIL (P=0.001). The relationship between CD4+ T-lymphocyte cell counts and the severity of cervical SIL was significant (P=0.007). Marital status and number of lifetime sex partners were risk factors significantly associated with SIL (P=0.004 and 0.005, respectively). SIL was not associated with age, education level, parity or age at sex debut. The prevalence and severity of cervical SIL was significantly associated with HIV infection and immunologic disease progression. These findings underscore the need for HIV screening among women with SIL, and the need for cervical cancer screening in HIV-infected women. Marital status and number of lifetime sex partners were significant risk factors associated with SIL
