Risk Factors of Preterm Delivery in the Lao PDR: Hospital-Based Matched Case-Control Study.

OBJECTIVE: To describe the risk factors among mothers in four central hospitals and two provincial hospitals in the Lao PDR, a lower-middle-income country in Southeast Asia. METHOD: The study used a hospital-based matched case-control design study. Purposive sampling was used to select 320 mothers (80 cases and 240 controls) from the six hospitals. Cases were mothers who had delivered a live newborn between 28 and 36 weeks and 6 days, while controls were mothers who had delivered a live newborn within 37 and 40 weeks. Data were collected through a review of medical records and face-to-face interviews using a structured questionnaire. Data were entered into EPI info (Version 3.1) then exported to the STATA programme (Version 14) for univariate and conditional multiple logistic regressions to identify risk factors for PTD at p ≤ 0.05. RESULTS: The mean maternal age of cases and controls was 25.2 (SD = 5.33) and 25.8 (SD = 4.37), respectively. In the multivariate analysis, factors with statistically significant relationships with PTD were the mother's religion (AOR: 3.01; 95% CI 1.24-7.26), the number of antenatal care visits (AOR: 3.39; 95% CI 1.6-7.18), having a pre-pregnancy maternal weight of less than 45 kg (AOR: 3.05; 95% CI 1.66-10.5), having had a premature preterm rupture of the membrane (AOR: 7.13; 95% CI 2.44-20.8) and vaginal bleeding during pregnancy (AOR: 6.89; 95% CI 3.02-15.73). CONCLUSIONS FOR PRACTICE: Improving capacity of the Laotian health system to provide quality ANC and increasing the number of ANC contacts is critical. This requires context specific strategies that also address the socio-economic factors, such as access to a nutritious diet, that contribute to PTD.

Job satisfaction of health workers at a Vietnamese University Hospital and its predicted factors: A cross-sectional study.

Background and Aims: Job satisfaction of healthcare workers from conventional and university hospitals (or teaching hospitals) might be different due to several factors, for example medical staff required to carry out multiple clinical and teaching tasks simultaneously. Our study aimed to determine how the job satisfaction among healthcare workers in university hospitals is different from those in conventional hospitals. Methods: A cross-sectional study was conducted by using the validated and contextualized job satisfaction tool for the Vietnamese context to survey 216 healthcare workers at a university hospital in Vietnam from January to March 2020 with online Google forms. Results: The results indicated low overall job satisfaction (43.1%) in our study university hospital with the score cutoff of 80%. However, healthcare workers still reported high job satisfaction rates in certain aspects, such as personal empathy (70.8%), discipline, and reward (67.6%), co-worker collaboration (65.3%), training and promotion (63%), workplace environment (57.4%), and salary and allowance (44.9%). Subgroup analysis revealed statistically significant differences in job satisfaction (p < 0.01) related to age (31 to 40-year-old), and job position with ORs 3.9, and 8.6 respectively. Conclusion: University hospitals need to improve the healthcare workers' job satisfaction. It is recommended that special human resource strategies should be developed focusing on keeping satisfying older healthcare staff by recognizing their contributions and providing appropriate benefits based on their positions in the hospital.

Investigation of ortho-positronium annihilation for porous materials with different geometries and topologies.

In this work, we present the results of the ortho-positronium (o-Ps) annihilation lifetimes and nitrogen adsorption measurements for different porous materials and an approach for describing the annihilation of o-Ps in a pore, which results in a surface-volume formula (SVF) for calculating the pore-related o-Ps lifetime. This proposed formula gives the relationship between the o-Ps annihilation rate and the effective pore radius, bulk composition, and pore structure, including pore geometry and topology. The pore-related o-Ps lifetimes of different materials calculated by the SVF are consistent with experimental results for both micro- and mesopores (and macropores) with different geometries and topologies. The SVF is convenient for calculations of pore dimensions for many cases of metal organic frameworks and zeolites. This approach enables us to fully explain the temperature dependence of the o-Ps annihilation lifetime over a wide temperature range, 20-700 K.

Health staff's job motivation post COVID-19 pandemic: A case study in Vietnam.

Objectives: Vietnam has witnessed a severe shortage of qualified staff in the public health sector after the COVID-19 pandemic. Our cross-sectional study aimed to identify job motivation and associated factors among experienced frontline health staff working in public health in order to have preventive measures in the event of future pandemics. Methods: A cross-sectional study, from March 2022 to November 2022 at a Vietnamese public hospital, on the job motivation and the predicted factors of 381 healthcare workers who participated in the frontlines of the COVID-19 pandemic from 2020 to 2021. The survey tool, developed by Mbindyo Patrick (2009), includes three components: (i) job satisfaction, (ii) organizational commitment, and (iii) conscientiousness. The survey tool was revalidated in our study with structural equation model for the construction of job motivation model and confirmatory factor analysis for certifying the elementary three components (factors) of the tool. And the tool's reliability was evaluated by Cronbach's Alpha. Bivariate analysis and multiple logistic regression were used to identify the predicted factors with the job motivation cutoff of 4.0. Results: The tool for job motivation constructs showed all specifications were good fit indices and the Cronbach's Alpha was 0.85. The job motivation of health staff decreased dramatically in all dimensions post COVID-19 pandemic, with a mean score of 3.26. Job satisfaction and organizational commitment were the most negatively impacted areas, with scores of 3.02 and 3.00, respectively. The predicted factors of low job motivation were young age (less than 30 years old), low monthly income (less than $400), high qualification, and non-managerial positions with odds ratio of 2.27, 2.5, 2.09, and 3.61, respectively. Conclusion: Following the COVID-19 outbreak in Vietnam, healthcare workers who had been in the frontlines of the COVID-19 pandemic, had experienced a significant decline in their job motivation, despite their continued employment at public hospitals.

Effects of Heatwaves on Hospital Admissions for Cardiovascular and Respiratory Diseases, in Southern Vietnam, 2010-2018: Time Series Analysis.

This study investigated the associations between heatwaves and daily hospital admissions for cardiovascular and respiratory diseases in two provinces in Viet Nam known to be vulnerable to droughts during 2010-2018. This study applied a time series analysis with data extracted from the electronic database of provincial hospitals and meteorological stations from the corresponding province. To eliminate over-dispersion, this time series analysis used Quasi-Poisson regression. The models were controlled for the day of the week, holiday, time trend, and relative humidity. Heatwaves were defined as the maximum temperature exceeding P90th over the period from 2010 to 2018 during at least three consecutive days. Data from 31,191 hospital admissions for respiratory diseases and 29,056 hospitalizations for cardiovascular diseases were investigated in the two provinces. Associations between hospital admissions for respiratory diseases and heatwaves in Ninh Thuan were observed at lag 2, with excess risk (ER = 8.31%, 95% confidence interval: 0.64-16.55%). However, heatwaves were negatively associated with cardiovascular diseases in Ca Mau, which was determined amongst the elderly (age above 60), ER = -7.28%, 95%CI: -13.97--0.08%. Heatwaves can be a risk factor for hospital admission due to respiratory diseases in Vietnam. Further studies need to be conducted to assert the link between heat waves and cardiovascular diseases.

Review of antibiotic prescriptions as part of antimicrobial stewardship programmes: results from a pilot implementation at two provincial-level hospitals in Viet Nam.

Objectives: To investigate the feasibility of retrospective prescription-based review and to describe the antibiotic prescribing patterns to provide information for an antimicrobial stewardship programme in Viet Nam. Methods: This study was conducted in two provincial-level hospitals between February and April 2020. Reviews were done by a clinical team consisting of leaders/senior doctors of each ward to assess the optimal level (optimal/adequate/suboptimal/inadequate/not assessable) of antibiotic prescriptions. Mixed-effect logistic regression at prescription level was used to explore factors associated with optimal antibiotic use. Results: The retrospective prescription-based review was accepted by study clinical wards with varied levels of participants. One hundred and eighty-three patients (326 prescriptions) in Hospital 1 and 200 patients (344 prescriptions) in Hospital 2 were included. One hundred and nineteen of the 326 (36.5%) antibiotic prescriptions in Hospital 1 and 51/344 (14.8%) antibiotic prescriptions in Hospital 2 were determined to be optimal by the review teams. The number of adequate antibiotic prescriptions were 179/326 (54.9%) and 178 (51.7%) in Hospital 1 and Hospital 2, respectively. The optimal level was lower for surgical prophylaxis antibiotics than for empirical therapy (OR = 0.06; 95% CI 0.01-0.45), higher in prescriptions in the ICU (OR = 12.00; 95% CI 3.52-40.92), higher in definitive antibiotic therapy (OR = 48.12; 95% CI 7.17-322.57) and higher in those with an indication recorded in medical records (OR = 3.46; 95% CI 1.13-10.62). Conclusions: This study provides evidence on the feasibility of retrospective prescription-based review, with adaption to the local situation. High and varying levels of optimal antibiotic prescriptions in clinical wards in hospitals were observed in Viet Nam.

Self-reported non-communicable diseases and associated socio-demographic status among ethnic minority populations in Vietnam, 2019.

The aim of this study was to report the prevalence of self-reported non-communicable diseases among ethnic minority populations in Vietnam and related factors. A total of 5033 individuals aged 15 years and older who belonged to ethnic minority populations from 12 provinces in Vietnam completed a household survey. The overall prevalence of self-reported non-communicable diseases was 12.4% (95% CI: 11.5%-13.4%). Cardiovascular diseases were the most prevalent, followed by diabetes. Ethnicity was shown to have an independently significant correlation to having any non-communicable diseases. Older people, near-poor and non-poor people had significantly higher odds of having non-communicable diseases as compared to younger and poor people.

Out-of-Pocket Health Expenditures Among Insured and Uninsured Patients in Vietnam.

Out-of-pocket expenditure/payment (OOP) is one of the indicators measuring the achievement of Universal Health Coverage. This article aimed to compare OOP among the insured and uninsured for their outpatient and inpatient health care services. The data of 6710 individuals using outpatient care and 924 individuals using inpatient care at 78 district hospitals and 246 commune health centers in 6 provinces from the World Bank survey, "The 2015 Vietnam District and Commune Health Facility," were used for analysis. In the ordinary least square model, the estimated coefficient of the insurance status variable suggested that insurance reduced OOP by 31.1% for outpatient care and 31.5% for inpatient care of the insured as compared with the uninsured (P <0.001). For outpatient care, insurance reduced OOP more for those enrollees using commune health centers than those using district health facilities, 42.3% and 20.2%, respectively. For inpatient care at district health facilities, insurance reduced OOP by 34.9% as compared with the uninsured (P <0.001). The study suggested that more active solutions should be created to promote the universal health insurance in Vietnam.

Validation of a Brief CES-D Scale for Measuring Depression and Its Associated Predictors among Adolescents in Chi Linh, Hai Duong, Vietnam.

OBJECTIVES: The aims of this paper were to confirm the validity and reliability of a brief CES-D measure for depression and identify the associated factors with the depression among adolescents and youth in Chi Linh, Hai Duong province, Vietnam. METHODS: We used data from a prospective-longitudinal study of adolescents and youth (aged 13-17 at baseline) and their parent (N = 1402 mother/father-child dyads). Adolescents' depression was assessed in 2009 and 2013. Parents' connectedness was measured in 2013. Confirmatory factor Analysis (CFA) was used to certify the elementary factors produced by PCA using Comparative Fit Index (CFI), Tucker Lewis Index (TLI) and RMSEA. Multivariate linear regression was used to predict the factors associated with depression. RESULTS: The results demonstrate that the depression items correspond as CFI (0.89), TLI (0.87) and RMSEA (0.084) are acceptable fit indices. The mean score of depression among adolescents and youth was 30.9 (Min = 16 and Max = 70; SD = 8.3). Age (ß = -0.01; CI 95% = -0.1; -0.03), parent and youth can talk freely (ß = -0.042; CI 95% = -0.08; -0.001) and good health status (ß = -0.07; CI 95% = -0.1; -0.03) were found to be significantly associated with depression. CONCLUSIONS: Depression scale should be widely applied for screening the depression symptoms of adolescents and youth population. The necessary strategies should be implemented to improve the adolescent and young population's depression status.

Evaluation of a gamma technique for the assay of radioactive waste drums using two measurements from opposing directions.

A technique using two measurements from opposing directions for the assay of the activity of radioactive waste drums, mainly consisting of organic materials, has been studied. A model for the calculation of systematic errors is given by simulating the measurement system. The calculated values are in good agreement with the experimental values. This confirms the validity of the model and proofs the good performance of this technique in practice. These results may provide guidelines for setting up a measuring system for the assay the radwaste drums.
