RESUMO

Cervical cancer is the most common female cancer in Eastern Africa, and the World Health Organization (WHO) recommends human papillomavirus (HPV)-based screening as a key element to eliminate the disease. In this cross-sectional study from Tanzania, we compared nine HPV-based cervical cancer screening strategies, including HPV testing at standard cut-off; HPV testing at increased viral load cut-offs; HPV testing with partial/extended genotyping, and HPV testing with visual inspection with acetic acid (VIA). We pooled data collected during 2008 to 2009 and 2015 to 2017 from 6851 women aged 25 to 65. Cervical cytology samples were HPV tested with Hybrid Capture 2, and HPV positive samples were genotyped with INNO-LiPA Extra II. Human immunodeficiency virus (HIV) testing and VIA were done according to local standards. We calculated sensitivity, specificity, positive and negative predictive value of screening strategies, with high-grade cytological lesions as reference, separately for women with and without HIV. HPV testing at standard cut-off (1.0 relative light units [RLU]) had highest sensitivity (HIV+: 97.8%; HIV-: 91.5%), but moderate specificity (HIV+: 68.1%; HIV-: 85.7%). Increasing the cut-off for HPV positivity to higher viral loads (5.0/10.0 RLU) increased specificity (HIV+: 74.2%-76.5%; HIV-: 89.5%-91.2%), with modest sensitivity reductions (HIV+: 91.3%-95.7%; HIV-: 83.5%-87.8%). Limiting test positivity to HPV types 16/18/31/33/35/45/52/58 improved specificity while maintaining high sensitivity (HIV+: 90.2%; HIV-: 81.1%). Triage with VIA and/or partial genotyping for HPV16/18 or HPV16/18/45 had low sensitivities (≤65%). In conclusion, HPV testing alone, or HPV testing with extended genotyping or increased viral load cut-offs, may improve cervical cancer screening in Sub-Saharan Africa.

RESUMO

BACKGROUND: Raising awareness of antimicrobial resistance is a cornerstone of action plans to tackle this global One Health challenge. Tools that can reliably assess levels of awareness of antibiotic resistance (ABR) among human or animal healthcare professionals (HCPs) are required to guide and evaluate interventions. METHODS: We designed and tested an ABR awareness scale, a self-administered questionnaire completed by human and animal HCPs trained to prescribe and dispense antibiotics in six countries-Ghana, Nigeria, Tanzania, Vietnam, Thailand and Peru. Questionnaires also elicited demographic, practice, and contextual information. Psychometric analysis for the scale followed Rasch Measurement Theory. Bivariate analysis was carried out to identify factors associated with awareness scores. RESULTS: Overall, 941 HCPs (625 human and 316 animal) from Ghana, Nigeria, Tanzania, Vietnam, Thailand and Peru were included in the study. The 23-item ABR awareness scale had high-reliability coefficients (0.88 for human and 0.90 for animal HCPs) but performed better within countries than across countries. Median ABR awareness scores were 54.6-63.5 for human HCPs and 55.2-63.8 for animal HCPs (scale of 0-100). Physicians and veterinarians scored higher than other HCPs in every country tested. HCPs in this study reported working in contexts with limited laboratory infrastructures. More than 95% of HCPs were interested in receiving information or training on ABR and antimicrobial stewardship. CONCLUSION: HCPs' awareness of ABR can be reliably assessed with this validated 23-item scale within the countries tested. Using the scale alongside context questions and objective measurement of practices is recommended to inform interventions to improve antibiotic use.

RESUMO

BACKGROUND: Human papilloma virus (HPV) is a sexually transmitted infection causing more than 80% of cervical cancers. WHO recommends using of sensitive screening methods like HPV-testing to timely prevent future morbidity and mortality from cervical cancer. Pilot studies have shown that HPV-testing is feasible and can be scaled in developing country like Tanzania. However, there is limited information on women understanding, reactions and psychological challenges following diagnosis of high risk HPV (HR-HPV). This study explored the knowledge of women on HPV and their experience after HPV positive results in Kilimanjaro, Tanzania. METHODS: The study was part of a larger study that assessed incidence and persistence of HR-HPV among women aged 18 years and above in Kilimanjaro. This was a cross sectional study conducted in Moshi municipal council among women who had HR-HPV positive results at enrollment. In-depth interviews were conducted with 13 randomly selected women who were attending for follow-up after enrollment. Interviews were conducted at the health facility and Atlas.ti.8 was used to analyze the data using thematic framework analysis. RESULTS: Women had knowledge on HPV infection but they had different reactions following receiving positive HPV results. Reaction toward the positive HPV results had two extremes; some women had psychological effect (hopeless, death sentence, having cancer, being shocked, failure to disclose and psychosexual effects) while others women explained positive results is good as they are identified earlier, will be followed up and it has made them plan to continue with cervical cancer screening in future. CONCLUSION: Women had knowledge on HPV, but positive results lead to negative and positive experiences by women. Clinicians and programs need to develop interventions and good strategies to minimize the psychological and social burden of testing positive for HPV.

RESUMO

OBJECTIVE: The objective of the present study was to assess the prevalence and type-specific distribution of cervical high-risk (HR) human papillomavirus (HPV) among women with normal and abnormal cytology, and to describe risk factors for HR HPV among HIV-positive and HIV-negative women in Tanzania. METHODOLOGY: A cross-sectional study was conducted in existing cervical cancer screening clinics in Kilimanjaro and Dar es Salaam. Cervical specimens were obtained from women aged 25-60 years. Samples were shipped to Denmark for cytological examination, and to Germany for HR HPV testing (using Hybrid Capture 2) and genotyping (using LiPaExtra). Risk factors associated with HPV were assessed by multivariable logistic regression analysis. RESULT: Altogether, 4080 women were recruited with 3416 women contributing data for the present paper, including 609 HIV-positive women and 2807 HIV-negative women. The overall HR HPV prevalence was 18.9%, whereas the HR HPV prevalence in women with high-grade squamous intraepithelial lesions (HSILs) was 92.7%. Among HPV-positive women with HSIL, HPV16 (32.5%) and HPV58 (19.3%) were the the most common types followed by HPV18 (16.7%) and HPV52 (16.7%). Factors associated with HR HPV included younger age, increasing number of partners and early age at first intercourse. Similar risk factors were found among HIV-positive and HIV-negative women. In addition, among HIV-positive women, those with CD4 counts <200 cells/mm3 had an increased risk of HR HPV (OR 2.2; 95% CI 1.2 to 4.8) compared with individuals with CD4 count ≥500 cells/mm3. CONCLUSION: Given the HPV distribution among Tanzanian women, the current HPV vaccination in Tanzania using quadrivalent vaccine may be considered replaced by the nonavalent vaccine in the future. In addition, appropriate antiretroviral treatment management including monitoring of viremia may decrease the burden of HR HPV in HIV-positive women.

RESUMO

INTRODUCTION: Exposure to intimate partner violence (IPV) has been found to be associated with a multitude of poor health and quality of life outcomes. Among the risks exacerbated by IPV is prenatal depression. Resilience is hypothesized to protect against psychopathology after exposure to a traumatic influence. The present study aims to investigate resilience as a moderator of the effect of exposure to IPV on prenatal depression among pregnant women in Moshi, Tanzania. MATERIAL AND METHODS: In this cross-sectional study, nested within a larger longitudinal study, pregnant women receiving antenatal care were interviewed about exposure to IPV, signs of depression using the Edinburgh Postpartum Depression Scale, and resilience using the abbreviated Connor-Davidson Resilience Scale. Logistic regression was used to test the effect of the interaction term of resilience and exposure to IPV during pregnancy on the risk of high level of signs of depression. RESULTS: In total, 1013 women completed all interviews, 300 women reported exposure to IPV, and 113 had high levels of signs of depression. Mean resilience score was 14.26 (SD 9.45). Exposure to IPV was correlated with signs of depression (adjusted odds ratio 6.49, 95% CI 3.75-11.24). Resilience was not correlated with signs of depression, nor was the interaction term of resilience and exposure to IPV. CONCLUSIONS: The study did not find that resilience acted as a moderator of the effect of exposure to IPV during pregnancy on the risk of prenatal depression. The cross-sectional design of the study may not be well suited to investigate resilience, which could take time to manifest. The abbreviated Connor-Davidson Resilience Scale has not been validated in a Tanzanian setting, or in the Swahili version. Practitioners should take note that all women and families affected by IPV should be afforded relevant assistance from social services, law enforcement, healthcare practitioners, and other relevant services, regardless of their apparent level of resilience.

RESUMO

INTRODUCTION: Visual inspection of the cervix with acetic acid is used to control the burden of cervical cancer in low- and middle-income countries. This method has some limitations and HPV DNA testing may be an alternative, but it is expensive and requires a laboratory setup. Cheaper and faster HPV tests have been developed. This study describe the agreement between a fast HPV test (careHPV) and hybrid capture 2 (HC2) in detection of high-risk HPV among Tanzanian women. MATERIAL AND METHODS: The study involved women attending routine cervical cancer screening at the Ocean Road Cancer Institute and Kilimanjaro Christian Medical Centre in Tanzania. The women were offered HIV testing. Two cervical samples were subsequently obtained; the first sample was processed at the clinics using careHPV and the second sample was transported to Denmark and Germany for cytology and HC2 analysis. Kappa statistic was calculated to assess the agreement between careHPV and HC2. The sensitivity, specificity and predictive values of careHPV were calculated using HC2 as reference. The analyses were done for the overall study population and stratified by testing site and HIV status. RESULTS: A total of 4080 women were enrolled, with 437 being excluded due to invalid information, lack of careHPV or HC2 results. Overall agreement between the tests was substantial with a kappa value of 0.69 (95% confidence interval [CI] 0.66-0.72). The sensitivity and specificity of careHPV was 90.7% (95% CI 89.6-91.8) and 84.2% (95% CI 81.2-86.8), respectively. The agreement was similar in the stratified analyses where the kappa values were 0.75 (95% CI 0.70-0.79) in women aged 25-34, 0.66 (95% CI 0.62-0.70) in women aged 35-60, 0.73 (95% CI 0.70-0.77) at the Ocean Road Cancer Institute, 0.64 (95% CI 0.60-0.69) at the Kilimanjaro Christian Medical Center, 0.73 (95% CI 0.68-0.79) in HIV-positive and 0.66 (95% CI 0.63-0.70) in HIV-negative women. The kappa value of 0.64 (95% CI 0.39-0.88) for cervical high-grade lesions indicates a substantial agreement between careHPV and HC2 in detecting HPV among women with cervical high-grade lesions. CONCLUSIONS: A substantial agreement was found between careHPV and HC2 in detecting HPV overall as well as detecting HPV among women with cervical high-grade lesions. However, given the limited resources available in low and middle-income countries, the HPV testing assay should be weighed against the cost-effectiveness of the test.

RESUMO

INTRODUCTION: Human papillomavirus (HPV) is the causative agent of precancerous lesions and cervical cancer, cervical cancer being the leading cause of deaths in Tanzanian women. Early detection and treatment of precancerous lesions are important in the prevention of cervical cancer cases. MATERIAL AND METHODS: We conducted a cross-sectional study among 3390 Tanzanian women aged 25-60 years. Information on lifestyle habits was collected, and women underwent gynecological examination with collection of cervical cells for conventional cytological and HPV testing. Blood samples were tested for HIV. The association between cervical high-grade cytology (HGC) and potential risk factors was examined using multivariable logistic regression adjusting for age and high-risk HPV (HR-HPV). RESULTS: The prevalence of HGC was 3.6% and of low-grade cytology was 8.3%. In women who were both HR-HPV-positive and HIV-positive, the prevalence of HGC was 28.3%. It increased by age and was 47% among women aged 50-60 years. Women, who had their sexual debut at age 9-15 years and 16-18 years, respectively, had 2.5 and 2.4 times increased odds of HGC compared with women whose sexual debut was at age 21 years and older. HIV-positive women had increased odds of HGC in comparison with HIV-negative women after adjustment for age (odds ratio [OR] 2.95, 95% CI 1.92-4.54). HR-HPV-positive women had nearly 100-fold increased odds of HGC compared with HR-HPV-negative women (OR 96.6, 95% CI 48.0-194), and this estimate was higher among HIV-positive women (OR 152.2, 95% CI 36.1-642.0). CONCLUSIONS: Increasing age, early age at first intercourse, HR-HPV, and HIV infections were associated with a substantially increased risk of HGC.

RESUMO

BACKGROUND: Rapid human papillomavirus (HPV) DNA testing is an emerging cervical cancer screening strategy in resource-limited countries, yet it requires follow-up of women who test HPV positive. OBJECTIVE: This study aimed to determine if one-way text messages improved attendance to a 14-month follow-up cervical cancer screening among HPV-positive women. METHODS: This multicenter, parallel-group randomized controlled trial was conducted at 3 hospitals in Tanzania. Eligible participants were aged between 25 and 60 years, had tested positive to a rapid HPV test during a patient-initiated screening, had been informed of their HPV result, and had a private mobile phone with a valid number. Participants were randomly assigned in a 1:1 ratio to the intervention or control group through an incorporated algorithm in the text message system. The intervention group received one-way text messages, and the control group received no text messages. The primary outcome was attendance at a 14-month health provider-initiated follow-up screening. Participants were not blinded, but outcome assessors were. The analysis was based on intention to treat. RESULTS: Between August 2015 and July 2017, 4080 women were screened for cervical cancer, of which 705 were included in this trial-358 women were allocated to the intervention group, and 347 women were allocated to the control group. Moreover, 16 women were excluded before the analysis because they developed cervical cancer or died (8 from each group). In the intervention group, 24.0% (84/350) women attended their follow-up screening, and in the control group, 23.8% (80/335) women attended their follow-up screening (risk ratio 1.02, 95% CI 0.79-1.33). CONCLUSIONS: Attendance to a health provider-initiated follow-up cervical cancer screening among HPV-positive women was strikingly low, and one-way text messages did not improve the attendance rate. Implementation of rapid HPV testing as a primary screening method at the clinic level entails the challenge of ensuring a proper follow-up of women.

RESUMO

BACKGROUND: Hypertension and Diabetes mellitus are risk factors for cardiovascular diseases that cause 17 million deaths globally. Many of these deaths could have been prevented if hypertensive and diabetic patients had their blood pressure and glucose controlled. Less than 30% of hypertensive and diabetic patients on management have controlled their blood pressure and glucose respectively. This study aimed to determine the preparedness of health facilities in managing hypertensive and diabetic patients in terms of personnel; laboratory services provision, and local use of routinely collected data, and shows differences in preparedness between the levels of facilities. METHODS: We conducted a cross-sectional study in Government, faith-based and private health facilities in two districts in Kilimanjaro region in Tanzania from March to July 2017. We collected data through interviews and observations on the preparedness of the facilities for managing hypertension and DM. RESULTS: Forty-three (43) health facilities and 62 healthcare workers (HCW) participated in the survey. Services for hypertension and DM were available in 37 (86%) and 34 (79%) health facilities respectively. Eighteen (53%) and five (15%) facilities had HCW trained on hypertension and DM management respectively within two years preceding the survey. Regular adherence to treatment guideline was reported in 18 (53%) of the health facilities. More than third of health facilities were without basic equipment for managing hypertension and DM. All the recommended laboratory tests were only available in four (15%) hospitals and one health center. Valid first line medicines for both hypertension and DM were available in six (50%) health centers, four (24%) dispensaries and in four (80.0%) hospitals. Health data collection, analysis and local use for planning were reported in all hospitals, nine (75%) health centers and four (24%) dispensaries. CONCLUSIONS: Health facilities are not fully prepared to manage hypertension and DM. Health centers and dispensaries are mostly affected levels of health facilities. Government interventions to improve facility factors and collaborative approaches to build capacity to HCW are needed to enable health facilities be responsive to these diseases.

RESUMO

Zanzibar is part of the United Republic of Tanzania with high levels of maternal mortality due to obstetric complications. Women's awareness on obstetric danger signs and early seeking of medical care is the first intervention in reduction of maternal deaths. This study explored awareness of danger signs among women of reproductive age in Unguja Island, Zanzibar. A community-based qualitative study using focus group discussions among women of reproductive age was conducted to explore awareness of danger signs between March and April 2016. Data was analyzed using thematic analysis. The study found that women were aware of danger signs during pregnancy but not during the post-delivery period. The mentioned danger signs during pregnancy included vaginal bleeding, fits, swelling of the legs and leaking of vagina fluid. Some women still believed that danger signs during pregnancy and post-delivery period were due to witchcraft leading to consultations with traditional healers and hence delays in seeking skilled medical care. In this context of misconceptions and cultural beliefs there should be investment in health education on danger signs to the community in general with involvement of traditional birth attendants and traditional healers who might play a role in advising and referring women with danger signs to the health facilities for care.

RESUMO

BACKGROUND: Intimate Partner Violence (IPV) is a significant public health problem with negative health consequences for women and their pregnancies. While social support has a protective effect against IPV and reduces health consequences of violence, its association with experiencing IPV during pregnancy remain less explored. In our study we aimed to determine the effect of social support on IPV during pregnancy among women attending antenatal care in Moshi, Tanzania METHODS: The study was part of a prospective cohort study that assessed the impact of violence on reproductive health of 1,116 participants. Pregnant women were enrolled below 24 weeks of gestation and followed until delivery. The experiences of social support and IPV during pregnancy were assessed at the 34th week of gestation. Logistic regression analysis was performed to assess the relationship between social support and IPV, with adjustment for potential confounders. RESULTS: The prevalence of IPV during pregnancy was 30.3% where the majority (29.0%) experienced repeated episodes of abuse. Regarding practical social support, having no one to help financially was associated with increased odds of IPV and repeated episodes of abuse during pregnancy, AOR 3.57, (95% CI 1.85 - 6.90) and AOR 3.21, (95% CI 1.69 - 6.11) respectively. For social support in terms of communication, talking to a member of the family of origin at least monthly was associated with decreased odds of IPV and repeated episodes of IPV during pregnancy, AOR 0.46 (95% CI 0.26 - 0.82) and AOR 0.41 (95% CI 0.23 - 0.73) respectively. Perceiving that family of origin will not offer support was associated with a increased odds of IPV and repeated episodes of IPV, AOR 2.29, (95% CI 1.31 - 3.99) and AOR 2.14, (95% CI 1.23 - 3.74) respectively. CONCLUSIONS: Nearly one third of women experienced IPV during pregnancy. Social support to women is associated with decreased odds of experiencing IPV during pregnancy. The family of origin plays an important role in providing social support to women who experience abuse during pregnancy; however, their true involvement in mitigating the impact of violence in the African setting needs further research.

RESUMO

BACKGROUND: Intimate Partner Violence (IPV) has serious negative health effects to millions of women around the globe. While disclosing IPV could open doors for support and eventually prevent partner abuse, the factors associated with IPV disclosure during pregnancy are not well known. The aim of this study was to examine factors influencing IPV disclosure to any person of interest or organization supporting women during pregnancy in Moshi Municipality, Tanzania. METHODS: Data were from a prospective cohort study of 1123 pregnant women followed-up by the project aiming to assess the impact of violence in the reproductive health conducted in Moshi Municipality, Tanzania from March 2014 to May 2015. Inclusion criteria to the current analysis were all 339 pregnant women who reported to have experienced physical, sexual and/or emotional violence during the index pregnancy. Data analysis used SPSS Version 20. Odds ratio with 95 % Confidence Interval (CI) for factors associated with IPV disclosure was estimated using multivariate logistic regression models while controlling for age, education and parity. A p-value of less than 0.05 was considered for a statistically significant difference. RESULTS: IPV disclosure was found to be 23.3 % (n = 79). Disclosure of IPV was less likely among unemployed (OR = 0.5, 95 % CI 0.30-0.90) and women whose index pregnancy was unplanned (OR = 0.53, 95 % CI 0.29-0.98). Women who regularly participated in women's or community groups, religious groups or political associations at least once a month had 2 times higher odds of IPV disclosure compared to those who did not attend regularly (OR = 2.12, 95 % CI 1.13-3.95). Most of the abused women during pregnancy who disclosed their experience of IPV (69 %) disclosed to a member of the family of birth followed by friends (14 %) and a member of family of the partner (11 %). CONCLUSIONS: Most of the women who experienced IPV during pregnancy kept suffering in silence while less than a quarter of all the abused (23.3 %) disclosed their experience to someone. Identification of the women experiencing IPV during pregnancy should be done as a starting point for supporting victim of IPV. Women empowerment in economical and reproductive health will reduce their vulnerability and facilitate disclosure of IPV for support. Key individuals who informally support victims of IPV should be targeted in interventions.

RESUMO

BACKGROUND: Preexposure prophylaxis with antiretroviral drugs has been effective in the prevention of human immunodeficiency virus (HIV) infection in some trials but not in others. METHODS: In this randomized, double-blind, placebo-controlled trial, we assigned 2120 HIV-negative women in Kenya, South Africa, and Tanzania to receive either a combination of tenofovir disoproxil fumarate and emtricitabine (TDF-FTC) or placebo once daily. The primary objective was to assess the effectiveness of TDF-FTC in preventing HIV acquisition and to evaluate safety. RESULTS: HIV infections occurred in 33 women in the TDF-FTC group (incidence rate, 4.7 per 100 person-years) and in 35 in the placebo group (incidence rate, 5.0 per 100 person-years), for an estimated hazard ratio in the TDF-FTC group of 0.94 (95% confidence interval, 0.59 to 1.52; P=0.81). The proportions of women with nausea, vomiting, or elevated alanine aminotransferase levels were significantly higher in the TDF-FTC group (P=0.04, P<0.001, and P=0.03, respectively). Rates of drug discontinuation because of hepatic or renal abnormalities were higher in the TDF-FTC group (4.7%) than in the placebo group (3.0%, P=0.051). Less than 40% of the HIV-uninfected women in the TDF-FTC group had evidence of recent pill use at visits that were matched to the HIV-infection window for women with seroconversion. The study was stopped early, on April 18, 2011, because of lack of efficacy. CONCLUSIONS: Prophylaxis with TDF-FTC did not significantly reduce the rate of HIV infection and was associated with increased rates of side effects, as compared with placebo. Despite substantial counseling efforts, drug adherence appeared to be low. (Supported by the U.S. Agency for International Development and others; FEM-PrEP ClinicalTrials.gov number, NCT00625404.).

RESUMO

Low- and middle-income countries have a high number of orphans, many of whom have unmet mental health needs. Effective mental health interventions are needed; however, it is necessary to understand how mental health symptoms and needs are perceived locally to tailor interventions and refine measurement of intervention effects. We used an existing rapid ethnographic assessment approach to identify mental health problems from the perspective of orphans and guardians to inform a subsequent randomized controlled trial of a Western-developed, evidence-based psychosocial intervention, Trauma-focused Cognitive Behavioral Therapy. Local Kiswahili-speaking interviewers conducted 73 free list interviews and 34 key informant interviews. Results identified both common cross-cultural experiences and symptoms as well as uniquely described symptoms (e.g., lacking peace, being discriminated against) not typically targeted by the intervention or included on standardized measures of intervention effects. We discuss implications for adapting mental health interventions in low- and middle-income countries and assessing effectiveness.

RESUMO

OBJECTIVE: To investigate the association, if any, between child mortality and distance to the nearest hospital. METHODS: The study was based on data from a 1-year study of the cause of illness in febrile paediatric admissions to a district hospital in north-east Tanzania. All villages in the catchment population were geolocated, and travel times were estimated from availability of local transport. Using bands of travel time to hospital, we compared admission rates, inpatient case fatality rates and child mortality rates in the catchment population using inpatient deaths as the numerator. RESULTS: Three thousand hundred and eleven children under the age of 5 years were included of whom 4.6% died; 2307 were admitted from <3 h away of whom 3.4% died and 804 were admitted from ≥ 3 h away of whom 8.0% died. The admission rate declined from 125/1000 catchment population at <3 h away to 25/1000 at ≥ 3 h away, and the corresponding hospital deaths/catchment population were 4.3/1000 and 2.0/1000, respectively. Children admitted from more than 3 h away were more likely to be male, had a longer pre-admission duration of illness and a shorter time between admission and death. Assuming uniform mortality in the catchment population, the predicted number of deaths not benefiting from hospital admission prior to death increased by 21.4% per hour of travel time to hospital. If the same admission and death rates that were found at <3 h from the hospital applied to the whole catchment population and if hospital care conferred a 30% survival benefit compared to home care, then 10.3% of childhood deaths due to febrile illness in the catchment population would have been averted. CONCLUSIONS: The mortality impact of poor access to hospital care in areas of high paediatric mortality is likely to be substantial although uncertainty over the mortality benefit of inpatient care is the largest constraint in making an accurate estimate.

RESUMO

BACKGROUND: Community perception in biomedical research remains critical in Africa with many participants being driven by different motives. The objective of this study was to explore the perceived motives for women or females guardians to volunteer for their children to participate in biomedical research and to explore experiences and challenges faced by Community Owned Resource Persons (CORPs) when mobilizing community members to participate in biomedical research. METHODS: This cross sectional study was conducted in Korogwe district, in north-eastern Tanzania. Qualitative methods combining random and purposive sampling techniques were used for data collection. A randomly selected sample using random table method from the existing list of households in the ward office was used to select participants for Focus Group Discussions (FGDs). A purposive sampling technique was used for In-Depth Interviews (IDIs) with CORPs. Thematic framework analysis was used to analyze the data. RESULTS: Need for better health services, availability of qualified clinicians, and better access to services provided at the research points were reported as main motives for community members to participate in biomedical research. With regard to experience and challenges faced by CORPs, the main reasons for mothers and guardians not participating in biomedical research were linked to misconception of the malariometric surveys, negative perception of the validity and sensitivity of rapid diagnostic tests, fear of knowing Human Immunodeficiency Virus Infection (HIV)/Acquired Immune Deficiency Syndrome (HIV/AIDS) sero status, and lack of trust for the medical information provided by the CORPs. Challenges reported by CORPs included lack ofawareness of malariometric surveys among participants, time consumption in mobilization of the community, difficulties in identifying individual results, and family responsibilities. CONCLUSION: This study has shown that majority of community members had positive perceptions of the about malariometric surveys services provided. The availability of free health services was the major determining factor for community members' participation in malariometric surveys. CORPs are instrumental in mobilizing community members participation during malariometric surveys, despite their experiences and the challenges they face.

RESUMO

This study was designed to test the feasibility and child clinical outcomes for group-based trauma-focused cognitive behavior therapy (TF-CBT) for orphaned children in Tanzania. There were 64 children with at least mild symptoms of grief and/or traumatic stress and their guardians who participated in this open trial. The TF-CBT for Child Traumatic Grief protocol was adapted for use with a group, resulting in 12 weekly sessions for children and guardians separately with conjoint activities and 3 individual visits with child and guardian. Using a task-sharing approach, the intervention was delivered by lay counselors with no prior mental health experience. Primary child outcomes assessed were symptoms of grief and posttraumatic stress (PTS); secondary outcomes included symptoms of depression and overall behavioral adjustment. All assessments were conducted pretreatment, posttreatment, and 3 and 12 months after the end of treatment. Results showed improved scores on all outcomes posttreatment, sustained at 3 and 12 months. Effect sizes (Cohen's d) for baseline to posttreatment were 1.36 for child reported grief symptoms, 1.87 for child-reported PTS, and 1.15 for guardian report of child PTS.

RESUMO

BACKGROUND: In recent years, Performance Based Financing (PBF); a form of result based financing, has attracted a global attention in health systems in developing countries. PBF promotes autonomous health facilities, motivates and introduces financial incentives to motivate health facilities and health workers to attain pre-determined targets. To achieve this, the Tanzanian government through the Christian Social Services Commission initiated a PBF pilot project in Rungwe district, Mbeya region. Kilimanjaro Christian Medical Center was given the role of training health workers on PBF principles in Rungwe. The aim of this study was to explore health care providers' perception on a three years training on PBF principles in a PBF pilot project at Rungwe District in Mbeya, Tanzania. METHODS: This was an explorative qualitative study, which took place at Rungwe PBF pilot area in October 2012. Twenty six (26) participants were purposively selected. Six took part in- depth interviews (IDIs) and twenty (20) in the group discussions. Both the IDIs and the GDs explored the perceived benefit and challenges of implementing PBF in their workplace. Data were manually analyzed using content analysis approach. RESULTS: Overall informants had positive perspectives on PBF training. Most of the health facilities were able to implement some of the PBF concepts in their work places after the training, such as developing job descriptions for their staff, creating quarterly business plans for their facilities, costing for their services and entering service agreement with the government, improved record keeping, customer care and involving community as partners in running their facilities. The most common principle of paying individual performance bonuses was mentioned as a major challenge due to inadequate funding and poor design of Rungwe PBF pilot project. CONCLUSION: Despite poor design and inadequate funding, our findings have shown some promising results after PBF training in the study area. The findings have highlighted the potential of PBF to act as leverage for initiating innovative and proactive actions, which may motivate health personnel performance and quality of care in the study setting with minimal support. However, key policy issues at the national level should be addressed in order to exploit this opportunity.

RESUMO

OBJECTIVES: To estimate the recurrence risk of preterm delivery and estimate the perinatal mortality in repeated preterm deliveries. METHODS: Prospective study in Tanzania of 18 176 women who delivered a singleton between 2000 and 2008 at KCMC hospital. The women were followed up to 2010 for consecutive births. A total of 3359 women were identified with a total of 3867 subsequent deliveries in the follow-up period. Recurrence risk of preterm birth and perinatal mortality was estimated using log-binomial regression and adjusted for potential confounders. RESULTS: For women with a previous preterm birth, the risk of preterm birth in a subsequent pregnancy was 17%. This recurrence risk was estimated to be 2.7-fold (95% CI: 2.1-3.4) of the risk of women with a previous term birth. The perinatal mortality of babies in a second preterm birth of the same woman was 15%. Babies born at term who had an older sibling that was born preterm had a perinatal mortality of 10%. Babies born at term who had an older sibling who was also born at term had a perinatal mortality of 1.7%. CONCLUSION: Previous delivery of a preterm infant is a strong predictor of future preterm births in Tanzania. Previous or repeated preterm births increase the risk of perinatal death substantially in the subsequent pregnancy.

RESUMO

BACKGROUND: Studies conducted thus far have demonstrated that the malaria vaccine (RTS,S) has a promising safety profile. Within the context of planning for future vaccine trials and for the purpose of building on previous research that has been undertaken in sub-Saharan Africa with regard to community perceptions about clinical studies, this research aimed to explore the community perceptions on the secondary health benefits established by the malaria vaccine trials (RTS,S Phase 2 and Phase 3) at the Korogwe site in Tanzania. METHODS: An exploratory qualitative study design was used. Participants were recruited from the Korogwe site. Sampling techniques were purposive and random. A total of five focus group discussions and six in-depth interviews were conducted. Interview guides with open-ended questions were employed to collect data. Male and female parents whose infants participated and those whose infants did not participate in the trials, health workers and community leaders were interviewed. Thematic analysis framework was used to analyse the data. RESULTS: The activities of a malaria vaccine project appeared to be well known to the community. Respondents had largely positive views towards the secondary health benefits which have been established by malaria vaccine trials. The project has led to a massive investment in health care infrastructure and an improvement in health care services across the study areas. The project was perceived by the community to have established major secondary health benefits. Misconceptions amongst respondents, especially with regard to blood samples, were also observed in this study. CONCLUSION: Despite some misconceptions with regard to the conduct of malaria vaccine trials, especially on blood sampling, generally this study observed that most participants were positive about the secondary health benefits brought about by the malaria vaccine trials in Korogwe.
