Social capital and the decline in HIV transmission - A case study in three villages in the Kagera region of Tanzania.

We present data from an exploratory case study characterising the social capital in three case villages situated in areas of varying HIV prevalence in the Kagera region of Tanzania. Focus group discussions and key informant interviews revealed a range of experiences by community members, leaders of organisations and social groups. We found that the formation of social groups during the early 1990s was partly a result of poverty and the many deaths caused by AIDS. They built on a tradition to support those in need and provided social and economic support to members by providing loans. Their strict rules of conduct helped to create new norms, values and trust, important for HIV prevention. Members of different networks ultimately became role models for healthy protective behaviour. Formal organisations also worked together with social groups to facilitate networking and to provide avenues for exchange of information. We conclude that social capital contributed in changing HIV related risk behaviour that supported a decline of HIV infection in the high prevalence zone and maintained a low prevalence in the other zones

Maternal near-miss and death and their association with caesarean section complications: a cross-sectional study at a university hospital and a regional hospital in Tanzania

Background The maternal near-miss (MNM) concept has been developed to assess life-threatening conditions during pregnancy, childhood, and puerperium. In recent years, caesarean section (CS) rates have increased rapidly in many low- and middle-income countries, a trend which might have serious effects on maternal health. Our aim was to describe the occurrence and panorama of maternal near-miss and death in two low-resource settings, and explore their association with CS complications. Methods We performed a cross-sectional study, including all women who fulfilled the WHO criteria for MNM or death between February and June 2012 at a university hospital and a regional hospital in Dar es Salaam, Tanzania. Cases were assessed individually to determine their association with CS. Main outcome measures included MNM ratio; maternal mortality ratio; proportion of MNM and death associated with CS complications; and the risk for such outcomes per 1,000 operations. The risk ratio of life-threatening CS complications at the university hospital compared to the regional hospital was calculated. Results We identified 467 MNM events and 77 maternal deaths. The MNM ratio was 36 per 1,000 live births (95% CI 33–39) and the maternal mortality ratio was 587 per 100,000 live births (95% CI 460–730). Major causes were eclampsia and postpartum haemorrhage, but we also detected nine MNM events and five deaths from iatrogenic complications. CS complications accounted for 7.9% (95% CI 5.6–11) of the MNM events and 13% (95% CI 6.4–23) of the maternal deaths. The risk of experiencing a life-threatening CS complication was three times higher at the regional hospital (22/1,000 operations, 95% CI 12–37) compared to the university hospital (7.0/1,000 operations, 95% CI 3.8–12) (risk ratio 3.2, 95% CI 1.5–6.6). Conclusions The occurrence of MNM and death at the two hospitals was high, and many cases were associated with CS complications. The maternal risks of CS in low-resource settings must not be overlooked, and measures should be taken to avoid unnecessary CSs. More comprehensive training of staff, improved postoperative surveillance, and a more even distribution of resources within the health care system might reduce the risks of CS

Service screening with mammography of women aged 50–69 years in Sweden : effects on mortality from breast cancer

OBJECTIVES:To estimate the effect of the population based service screening programme in Sweden on mortality from breast cancer among women aged 50–69. SETTING:In 1986, population based service screening with mammography started in Sweden, and by 1997 screening had been introduced in all counties. Half of the counties invite women from 40 years of age whereas women 50 and older are invited in the other counties. The upper age limit was either 69 or 74. Women in the age group 50–69 years are thus invited to screening in all counties. METHODS:The counties which started with mammographic screening in 1986–87 constituted the study group and were compared with the counties which started in 1993 or later. In 1987 the mean number of women aged 50–69 was 161 986 and 98 608 in the study and control groups, respectively. Refined excess mortality (smoothed with the Lowess method) from breast cancer and refined cause specific mortality from breast cancer were used as effect measures. To adjust for geographical differences in mortality from breast cancer a reference period was used. Allowance was made for two potential biases: (a) inclusion bias implying the inclusion of cases diagnosed before invitation to screening in the first screening round, and (b) lead time bias. RESULTS:After a mean follow up time of 10.6 years since the start of screening and a mean individual follow up time of 8.4 years, a non-significant reduction in refined excess mortality for breast cancer was estimated as relative risk (RR) 0.84 (95% confidence interval (95% CI) 0.67 to 1.05). After adjustment for inclusion and lead time biases the RR was 0.80 (20% reduction). Only 27% of the deaths from breast cancer in the total mortality for women aged 50–79 at death consisted of women aged 50–69 at diagnosis who were diagnosed after the start of screening. This figure has important implications for judgement of the impact of screening on age specific national breast cancer mortalities. CONCLUSIONS:A non-significant reduction in mortality from breast cancer was found in counties performing service screening with mammography in Sweden. Adjustment for possible biases changed the result towards a larger effect of screening. The results do not contradict the effects found in the Swedish randomised mammography trials.digitalisering@um

Health coaching to promote healthier lifestyle among older people at moderate risk for cardiovascular diseases, diabetes and depression : a study protocol for a randomized controlled trial in Sweden

BACKGROUND: The challenge of an aging population in the society makes it important to find strategies to promote health for all. The aim of this study is to evaluate if repeated health coaching in terms of motivational interviewing, and an offer of wide range of activities, will contribute to positive lifestyle modifications and health among persons aged 60-75 years, with moderately elevated risk for cardiovascular disease (CVD), diabetes, or mild depression. METHODS/DESIGN: Men and women between 60 and 75 are recruited in four regions in Sweden if they fulfill one or more of the four inclusion criteria.•Current reading of blood pressure (140-159/90-99) without medication.•Current reading of blood sugar (Hba1c 42-52 mmol/mol) without medication.•A current waist-circumference of ≥94 cm for men and ≥80 for women.•A minor/mild depression (12-20 points) according to Montgomery-Åsberg Depression Rating Scale without medication.Individuals with a worse result than inclusion criteria are treated according to regular guidelines at the PHCs and therefore not included. Exclusion criteria for the study are dementia, mental illness or other condition deemed unsuitable for participation.All participants fill out a questionnaire at baseline, and at the 6-, 12- and 18-month follow-ups containing questions on demographic characteristics, social life, HRQoL, lifestyle habits, general health/medication, self-rated mental health, and sense of coherence. At the 12-month follow-up, the health coach will give each participant a second questionnaire to capture attitudes and perceptions related to health coaching and venues/activities offered.Qualitative data will be collected twice to obtain a deeper understanding of perceptions and attitudes related to health and lifestyle/lifestyle modifications. A health economic assessment will be performed. Individual costs for health care utilisation will be collected and QALY-scores will be estimated. DISCUSSION: Several drawbacks can be identified when conducting research in real life. However, many of the identified problems can diminish the positive results of the intervention and if the intervention shows positive effects they might be underestimated

Analysis of Perinatal Mortality at a Teaching Hospital in Dar es Salaam, Tanzania, 1999-2003

We conducted a retrospective analysis of perinatal mortality at Muhimbili National Hospital (MNH), Dar es Salaam, Tanzania 1999-2003 in order to categorise/classify perinatal deaths as well as to identify key factors in perinatal care that could be improved. Data were retrieved from the MNH obstetric database and causes of early neonatal deaths wereWe conducted a retrospective analysis of perinatal mortality at Muhimbili National Hospital (MNH), Dar es Salaam, Tanzania 1999-2003 in order to categorise/classify perinatal deaths as well as to identify key factors in perinatal care that could be improved. Data were retrieved from the MNH obstetric database and causes of early neonatal deaths were traced from the neonatal ward register. The study includes all foetuses weighing ≥500g. A modified Nordic-Baltic classification was used for classification of perinatal deaths. Over a 5-year period there were 77,815 babies born with a perinatal mortality rate of 124 per 1000 births, 78% of which was labour related stillbirth. The PMR was 913/1000 for singleton births and 723/1000 for multiple births for babies weighing less than 1500 grams and 65/1000 for singleton births and 116/1000 for multiple births for babies weighing 2500 grams or more. Babies weighing less than 1500 grams contributed 26% of PMR, whereas 41% occurred in babies weighing 2500 grams or more. The majority (79%) of neonatal deaths had Apgar score \u3c7 at 5 minutes and the most common causes of neonatal mortality were birth asphyxia (37%) and prematurity (29%). Labour related deaths were more common in multiple pregnancies. The majority of the perinatal deaths should be essentially avoidable through improved quality of intrapartum care. Establishment of perinatal audit at MNH can help identify key actions for improved care

Orphanhood and mistreatment drive children to leave home – A study from early AIDS-affected Kagera region, Tanzania

The aim of this mixed-method study was to explore the trajectories of leaving home, and views and experiences among children and youth in the Kagera region in Tanzania, who have lived on the streets or been domestic workers. The main results showed that orphanhood and mistreatment were the main reasons for leaving home: few children lived with their parents before they left, and leaving home was a complex process over several years where three trajectories were identified. The children who had left home showed strong agency and competency but lived in vulnerable conditions, especially young children living on the streets

Age-specific differences in tumour characteristics between screen-detected and non-screen-detected breast cancers in women aged 40–74 at diagnosis in Sweden from 2008 to 2017

Objective:  To analyze differences between screen-detected and non-screen-detected invasive breast cancers by tumour characteristics and age at diagnosis in the nationwide population-based mammography screening program in Sweden. Methods:  Data were retrieved from the National Quality Register for Breast Cancer for 2008-2017. Logistic regression analysis was used to estimate the likelihood for a tumour to be screen-detected by tumour characteristics and age group at diagnosis. Results:  In total there were 51,429 invasive breast cancers in the target age group for mammography screening of 40-74 years. Likelihood of screen detection decreased with larger tumour size, lymph node metastases, higher histological grade and distant metastasis. Odds ratios (ORs) for negative oestrogen (ER) and progesterone (PgR) were 0.41 and 0.57; for positive HER2, 0.62; for Ki-67 high versus low, 0.49. Molecular sub-types had OR of 0.56, 0.40 and 0.28, respectively, for luminal B-like, HER2-positive and triple negative versus luminal A-like. Adjusting for tumour size (T), lymph node status (N), age, year and county at diagnosis slightly elevated the ORs. Statistically significant interactions between tumour characteristics and age were found (p < 0.05) except for ER and PgR. The age group 40-49 deviated most from the other age groups. Conclusions:  Our study demonstrates that screen-detected invasive breast cancers had more favourable tumour characteristics than non-screen-detected after adjusting for age, year and county of diagnosis, and even after adjusting for T and N. The trend towards favourable tumour characteristics was less pronounced in the 40-49 age group compared to the other age groups, except for ER and PgR
