Addressing multiple modifiable risks through structured community-based Learning Clubs to improve maternal and infant health and infant development in rural Vietnam: protocol for a parallel group cluster randomised controlled trial

Introduction: Optimal early childhood development is an international priority. Risks during pregnancy and early childhood have lasting effects because growth is rapid. We will test whether a complex intervention addressing multiple modifiable risks: maternal nutrition, mental health, parenting capabilities, infant health and development and gender-based violence, is effective in reducing deficient cognitive development among children aged two in rural Vietnam. Methods and analysis: The Learning Clubs intervention is a structured programme combining perinatal stage-specific information, learning activities and social support. It comprises 20 modules, in 19 accessible, facilitated groups for women at a community centre and one home visit. Evidence-informed content is from interventions to address each risk tested in randomised controlled trials in other resource-constrained settings. Content has been translated and culturally adapted for Vietnam and acceptability and feasibility established in pilot testing. We will conduct a two-arm parallel-group cluster-randomised controlled trial, with the commune as clustering unit. An independent statistician will select 84/112 communes in Ha Nam Province and randomly assign 42 to the control arm providing usual care and 42 to the intervention arm. In total, 1008 pregnant women (12 per commune) from 84 clusters are needed to detect a difference in the primary outcome (Bayley Scales of Infant and Toddler Development Cognitive Score \u3c1 SD below standardised norm for 2 years of age) of 15% in the control and 8% in the intervention arms, with 80% power, significance 0.05 and intracluster correlation coefficient 0.03. Ethics and dissemination: Monash University Human Research Ethics Committee (Certificate Number 20160683), Melbourne, Victoria, Australia and the Institutional Review Board of the Hanoi School of Public Health (Certificate Number 017-377IDD- YTCC), Hanoi, Vietnam have approved the trial. Results will be disseminated through a comprehensive multistranded dissemination strategy including peer-reviewed publications, national and international conference presentations, seminars and technical and lay language reports

Biological dosimetry after radiosynoviorthesis with rhenium-186 sulphide and erbium-169 citrate

Zur Abschätzung der radiobiologischen Sicherheit des Verfahrens wird in dieser Arbeit die Radiosynoviorthese (RSO) mit Re-186 und Er-169 hinsichtlich biologischer Strahleneffekte untersucht. Bei 23 Patienten wurde eine RSO mit Rhenium-186-Sulfid- (10 Patienten) oder Erbium-169-Zitratkolloid (13 Patienten) durchgeführt. Das behandelte Gelenk wurde anschließend ruhig gestellt. Bei allen Patienten erfolgte vor und 17–19 Tage (Re-186) bzw. 45–50 Tage (Er-169) nach der RSO eine venöse Blutentnahme. Zur Analyse der Strahlenexposition wurde die Häufigkeit von dizentrischen Chromosomen in Lymphozyten der ersten Zellteilung in vitro bestimmt. Pro Patient wurden mindestens 1000 Zellen vor und nach der RSO untersucht, was nach längerer Einwirkung niederenergetischer Strahlung ausreichend ist, um im bestrahlten Kollektiv die im Rahmen der RSO erwarteten Strahlendosen nachzuweisen. Ergänzend wurde bei den mit Re-186 behandelten Patienten der Aktivitätsabtransport aus dem Gelenk mittels Ganzkörperszintigraphie bestimmt. In der Untersuchung von insgesamt 47017 Zellen fanden sich vor RSO mit Re-186 bzw. Er-169 40 bzw. 88, danach 59 bzw. 105 dizentrische Chromosomen in Lymphozyten des peripheren Blutes. Eine signifikante Zunahme der dizentrischen Chromosomen nach der RSO zeigte sich nicht. Der Aktivitätsabtransport nach RSO mit Re-186 lag durchschnittlich unter 5 % (unter 3 MBq) und ist damit als gering einzustufen. Die Ergebnisse der Untersuchung von Chromosomenaberrationen und des Aktivitätsabtransports nach Radiosynoviorthese mit Rhenium-186 und Erbium-169 sprechen für eine geringe Strahlenexposition der Patienten und damit für die Sicherheit des Verfahrens.The aim of the present studies was to investigate the biological radiation effect of radiosynoviorthesis (RSO) with Re-186 and Er-169 in order to evaluate the safety of this procedure. RSO with rhenium-186 sulfide colloid (10 patients) or erbium-169 citrate colloid (13 patients) was carried out in a total of 23 patients. Afterwards, the treated joint was immobilised for three days using splints. From all patients, blood was drawn immediately before and 17 to 19 days (Re-186) or 45 to 50 days (Er-169) after RSO. To evaluate the radiation dose, the yield of dicentric chromosomes in lymphocytes was determined exclusively in metaphases of the first cell cycle in vitro. At least 1000 cells per patient have been analysed before and after RSO which is sufficient to find potential radiation effects after long-term exposure to low energy radiation such as to expect after RSO. In addition, for Re-186 the activity leakage from the treated joint was measured by whole-body scintigraphy. In a total of 47017 cells analysed from 46 blood samples, 40 and 88 before and 59 and 105 dicentrics after RSO with Re-186 and Er-169 were found. This showed no statistically significant increase in the number of dicentric chromosomes. The measured average activity leakage of less than 5 % (less than 3 MBq) was considered to be low. The results of chromosome analysis and activity measurement after RSO prove that this procedure is associated with a low effective dose in treated patients and thus can be considered a safe treatment

Beyond the homestay: women’s participation in rural tourism development in Mekong Delta, Vietnam

This study examines the impact of the homestay tourism program in Mekong Delta, Vietnam, on women’s participation and empowerment in rural tourism development. As part of this study, 22 interviews were conducted with homestay owners to explore the benefits and challenges of women’s involvement in this type of tourism. The findings show that homestay tourism program has helped women to generate extra income, strengthen family ties, and increase their social influence while reducing domestic violence. However, cultural expectations and gender roles continue to pose challenges. This study underscores the importance of women’s participation in homestay tourism program and provides suggestions for promoting gender equality and women’s empowerment in tourism development. The study highlights the potential of women’s involvement in creating a sustainable and inclusive tourism industry and calls for further research and action to promote gender equality and women’s rights in tourism. The findings have practical implications for policymakers and practitioners in the tourism sector

Reduced bone loss is associated with reduced mortality risk in subjects exposed to nitrogen bisphosphonates: A mediation analysis

Bisphosphonates, potent anti-resorptive agents, have been found to be associated with mortality reduction. Accelerated bone loss is, in itself, an independent predictor of mortality risk, but the relationship between bisphosphonates, bone loss, and mortality is unknown. This study aimed to determine whether the association between bisphosphonates and mortality is mediated by a reduction in the rate of bone loss. Participants from the population‐based Canadian Multicentre Osteoporosis Study were followed prospectively between1996 and 2011. Comorbidities and lifestyle factors were collected at baseline and bone mineral density (BMD) at baseline and at years 3 (for those aged 40 to 60 years), 5, and 10. Rate of bone loss was calculated using linear regression. Information on medication use was obtained yearly. Bisphosphonate users grouped into nitrogen bisphosphonates (nBP; alendronate or risedronate) and etidronate and non‐users (NoRx) were matched by propensity score, including all baseline factors as well as time of treatment. Cox’s proportional hazards models, unadjusted and adjusted for annual rate of bone loss, were used to determine the association between nBP and etidronate versus NoRx. For the treatment groups with significant mortality risk reduction, the percent of mortality reduction mediated by a reduction in the rate of bone loss was estimated using a causal mediation analysis. There were 271 pairs of nBP and matched NoRx and 327 pairs of etidronate and matched NoRx. nBP but not etidronate use was associated with significant mortality risk reduction (hazard ratios [HR]=0.61 [95% confidenceinterval0.39–0.96]and1.35[95%CI0.86–2.11] for nBP and etidronate, respectively). Rapid bone loss was associated with more than2‐fold increased mortality risk compared with no loss. Mediation analysis indicated that39% (95%CI7%–84%) of the nBP association with mortality was related to a reduction in the rate of bone loss. This finding provides an insight into the mechanism of the relationship between nBP and survival benefit in osteoporotic patients

A Risk Assessment Tool for Predicting Fragility Fractures and Mortality in the Elderly

Existing fracture risk assessment tools are not designed to predict fracture-associated consequences, possibly contributing to the current undermanagement of fragility fractures worldwide. We aimed to develop a risk assessment tool for predicting the conceptual risk of fragility fractures and its consequences. The study involved 8965 people aged >= 60 years from the Dubbo Osteoporosis Epidemiology Study and the Canadian Multicentre Osteoporosis Study. Incident fracture was identified from X-ray reports and questionnaires, and death was ascertained though contact with a family member or obituary review. We used a multistate model to quantify the effects of the predictors on the transition risks to an initial and subsequent incident fracture and mortality, accounting for their complex interrelationships, confounding effects, and death as a competing risk. There were 2364 initial fractures, 755 subsequent fractures, and 3300 deaths during a median follow-up of 13 years (interquartile range [IQR] 7-15). The prediction model included sex, age, bone mineral density, history of falls within 12 previous months, prior fracture after the age of 50 years, cardiovascular diseases, diabetes mellitus, chronic pulmonary diseases, hypertension, and cancer. The model accurately predicted fragility fractures up to 11 years of follow-up and post-fracture mortality up to 9 years, ranging from 7 years after hip fractures to 15 years after non-hip fractures. For example, a 70-year-old woman with aT-score of -1.5 and without other risk factors would have 10% chance of sustaining a fracture and an 8% risk of dying in 5 years. However, after an initial fracture, her risk of sustaining another fracture or dying doubles to 33%, ranging from 26% after a distal to 42% post hip fracture. A robust statistical technique was used to develop a prediction model for individualization of progression to fracture and its consequences, facilitating informed decision making about risk and thus treatment for individuals with different risk profiles.

Lessons learned from implementation of a demonstration program to reduce the burden of anemia and hookworm in women in Yen Bai Province, Viet Nam

Background Iron deficiency, anemia and hookworm disease are important public health problems for women of reproductive age living in developing countries and affect the health of newborns and infants. Iron supplementation and deworming treatment are effective in addressing these problems in both pregnant and non-pregnant women. Daily iron supplementation and deworming after the first trimester is recommended for pregnant women although these programs usually do not operate efficiently or effectively. Weekly iron-folic acid supplementation and regular deworming for non-pregnant women may be a viable approach for improving iron status and preventing anemia during the reproductive years. Addressing these diseases at a population level before women become pregnant could significantly improve women's health before and during pregnancy, as well as their infants' growth and development. Methods and Results This paper describes the major processes undertaken in a demonstration intervention of preventive weekly iron-folic acid supplementation with regular deworming for all 52,000 women aged 15–45 years in two districts of Yen Bai province, in northern Viet Nam. The intervention strategy included extensive consultation with community leaders and village, commune, district and provincial health staff, and training for village health workers. Distribution of the drugs was integrated with the existing health service infrastructure and the village health workers were the direct point of contact with women. Iron-folic acid tablets and deworming treatment were provided free of charge from May 2006. An independent Vietnamese NGO was commissioned to evaluate compliance and identify potential problems. The program resulted in effective distribution of iron-folic acid tablets and deworming treatment to all villages in the target districts, with full or partial compliance of 85%. Conclusion Training for health staff, the strong commitment of all partners and the use of appropriate educational materials led to broad support for weekly iron-folic acid supplementation and high participation in the regular deworming days. In March 2008 the program was expanded to all districts in the province, a target population of approximately 250,000 WRA, and management was handed over to provincial authorities

Translation, Validity, and Reliability of Mental Health Literacy and Help-Seeking Behavior Questionnaires in Indonesia

Background and Aim: Mental health is an integral part of adolescent wellbeing. However, only few adolescents understand the importance of mental health and are aware of the right time to seek help. Lack of knowledge and stigma may impede help-seeking behavior. To assess these aspects, three questionnaires have been developed in the English language. This study aims to assess the validity and reliability of an Indonesian version of the Mental Health Literacy and Help-Seeking Behavior set of questionnaires among adolescents in Indonesia.Methods: This is a cross-sectional study that used The Mental Health Literacy and Help-Seeking Behavior set of questionnaires developed by Kutcher and Wei. The set consists of three questionnaires: the Mental Health Knowledge, Attitude Toward Mental Health, and Help-Seeking Behavior questionnaire. The study was conducted between October 2020 and January 2021 with 68 first-year medical students at the University of Indonesia, who represented adolescents in a transitional phase. The questionnaires were translated into the Indonesian language by a bilingual psychiatrist and reviewed by 10 expert psychiatrists to determine content validity [Item-Level Content Validity Index (I-CVI) and Scale-Level Content Validity Index (S-CVI)]. Cronbach's alpha values were used to assess internal consistency (reliability).Results: The content validity test produced positive results with an I-CVI scores of 0.7–1.0 and S-CVI scores of 0.87, 0.90, and 0.99 for the knowledge, attitude, and help-seeking behavior questionnaires, respectively. For the reliability test, Cronbach's alpha values were 0.780 for the attitude questionnaire and 0.852 for the help-seeking behavior questionnaire, while the value for the knowledge questionnaire was 0.521.Conclusion: The ability to properly measure mental health through the availability of accessible, valid, and understandable tools plays an important role in addressing mental health issues among adolescents. In the current study, the Indonesian translations of all three questionnaires examining knowledge, attitude, and help-seeking behavior were considered to be valid and reliable.</p

A free weekly iron-folic acid supplementation and regular deworming program is associated with improved hemoglobin and iron status indicators in Vietnamese women

Background Anemia due to iron deficiency is recognized as one of the major nutritional deficiencies in women and children in developing countries. Daily iron supplementation for pregnant women is recommended in many countries although there are few reports of these programs working efficiently or effectively. Weekly iron-folic acid supplementation (WIFS) and regular deworming treatment is recommended for non-pregnant women living in areas with high rates of anemia. Following a baseline survey to assess the prevalence of anemia, iron deficiency and soil transmitted helminth infections, we implemented a program to make WIFS and regular deworming treatment freely and universally available for all women of reproductive age in two districts of a province in northern Vietnam over a 12 month period. The impact of the program at the population level was assessed in terms of: i) change in mean hemoglobin and iron status indicators, and ii) change in the prevalence of anemia, iron deficiency and hookworm infections. Method Distribution of WIFS and deworming were integrated with routine health services and made available to 52,000 women. Demographic data and blood and stool samples were collected in baseline, and three and 12-month post-implementation surveys using a population-based, stratified multi-stage cluster sampling design. Results The mean Hb increased by 9.6 g/L (95% CI, 5.7, 13.5, p < 0.001) during the study period. Anemia (Hb<120 g/L) was present in 131/349 (37.5%, 95% CI 31.3, 44.8) subjects at baseline, and in 70/363 (19.3%, 95% CI 14.0, 24.6) after twelve months. Iron deficiency reduced from 75/329 (22.8%, 95% CI 16.9, 28.6) to 33/353 (9.3%, 95% CI 5.7, 13.0) by the 12-mnth survey, and hookworm infection from 279/366 (76.2%,, 95% CI 68.6, 83.8) to 66/287 (23.0%, 95% CI 17.5, 28.5) over the same period. Conclusion A free, universal WIFS program with regular deworming was associated with reduced prevalence and severity of anemia, iron deficiency and h

Mental Health Problems Among Indonesian Adolescents: Findings of a Cross-Sectional Study Utilising Validated Scales and Innovative Sampling Methods

Purpose This study aimed to estimate the prevalence of mental health problems and identify potential risk and protective exposures for adolescents in Indonesia. Methods An innovative sampling approach was applied to simultaneously recruit school- and community-based adolescents aged 16–18 years old from Jakarta (urban megacity) and South Sulawesi (remote province). We used multistage cluster sampling for in-school (N = 1,337) and respondent driven sampling for out-of-school (N = 824) adolescents. Mental health was measured using two validated scales: Kessler-10 and Center for Epidemiologic Studies Depression Scale-Revised . Psychiatric interviews were conducted in a subsample (N = 196) of students from Jakarta to validate the self-report scales. Results The estimated population prevalence of psychological distress and depression were 24.3% (95% CI = 21.5–27.2) and 12.6% (10.5–14.4) for in-school and 23.7% (20.7–26.7) and 23.5% (20.4–26.5) for out-of-school adolescents, respectively. In participants who completed a psychiatric interview, common psychiatric morbidities were social anxiety, depression, and suicidality. Compared to in-school females, male in-school adolescents reported a lower prevalence of psychological distress (16.9% (13.1–20.7) vs. 30.4% (26.4–34.4)) and depression (10.1% (7.2–13.1) vs. 14.6 (11.4–17.8)). By contrast, for out-of-school adolescents, males reported a higher prevalence of psychological distress (25.2% (21.6–28.9) vs. 20.2% (15.1–25.3)) and depression (26.3% (22.5–30.1) vs. 16.9% (11.8–21.9)). In-school adolescents who did not seek healthcare despite a perceived need were more likely to report psychological distress and depression. Discussion Adolescent mental health problems are highly prevalent in Indonesia, with substantial variation by gender, geography, and school enrolment. This study and its approach to sampling and measurement may serve as a model to improving mental health surveillance across other settings

Foregone health care in adolescents from school and community settings in Indonesia: a cross-sectional study

Background Adolescence is a development period marked by the onset of a new set of health needs. The present study sought to quantify the prevalence of foregone care (not seeking medical care when needed) and identify which adolescents are at greater risk of having unmet healthcare needs. Methods A multi-stage random sampling strategy was used to recruit school participants (grade 10–12) in two provinces in Indonesia. Respondent driven sampling was used to recruit out-of-school adolescents in the community. All participants completed a self-reported questionnaire which measured healthcare seeking behaviours, psychosocial wellbeing, use of healthcare services, and perceived barriers to accessing healthcare. Multivariable regression analysis was performed to examine factors associated with foregone care. Findings A total of 2161 adolescents participated in the present study and nearly one in four adolescents reported foregone care in the past year. Experiences of poly-victimisation and seeking care for mental health needs increased the risk of foregone care. In-school adolescents who reported psychological distress [adjusted risk ratio (aRR) = 1.88, 95%CI = 1.48–2.38] or had high body mass index (aRR = 1.25, 95%CI = 1.00–1.57) were at greater risk of foregone care. The leading reason for foregone care was lack of knowledge of available services. In-school adolescents predominantly reported non-access barriers to care (e.g., perception of the health concern or anxiety about accessing care) whereas most out-of-school adolescents reported access barriers (e.g., did not know where to get care or could not pay). Interpretation Foregone care is common among Indonesian adolescents, especially in adolescents with mental and physical health risks. Differences between in-school and out-of-school adolescents suggest that interventions to promote appropriate healthcare use will need tailoring. Further research is needed to determine causal relationships around barriers in access to healthcare
