Determining the factors impacting the quality of life among the general population in coastal communities in central Vietnam.

People living in coastal areas are frequently affected by natural disasters, such as floods and storms. This study aimed to assess the quality of life (QoL) of people living in disadvantaged coastal communes (subdivision of Vietnam) and identify their associated factors by using the World Health Organization's quality of life instrument (WHOQOL-BREF). To achieve this, a cross-sectional descriptive study was conducted on 595 individuals aged 18 years and above living in the coastal communes in Thua Thien Hue province, Vietnam, from October 2022 to February 2023. The results showed that the mean overall QoL (mean ± SD) was 61.1 ± 10.8. Among the four domains of QoL, the physical health (57.2 ± 12.3) domain had a lower score than the psychological health (61.9 ± 13.0), social relations (63.4 ± 13.4), and environment (61.9 ± 13.3) domains. The QoL score of the domains for participants affected by flooding was significantly lower than that of those not affected, except for social relations. Multivariable logistic regression showed that subjects with not good QoL had the educational background with no formal education (Odds ratio (OR) = 2.63, 95% CI 1.19-5.83), fairly poor/poor households (OR = 2.75, 95% CI 1.48-5.12), suffered Musculoskeletal diseases (OR = 1.61, 95% CI 1.02-2.56), unsatisfaction with health status (OR = 5.27, 95% CI 2.44-11.37), family conflicts (OR = 4.51, 95%CI 2.10-9.69), and low levels of social support (OR = 2.62; 95% CI 1.14-6.02). The analysis also revealed that workers (OR = 0.17, 95% CI 0.04-0.66) had a better QoL than farmer-fisherman. QoL in disadvantaged coastal communes was low, with the lowest scores in the physical health domain. Based on the socioeconomic factors associated with not good QoL identified here, it is recommended that local authorities take more appropriate and practical measures to increase support, including measures for all aspects of physical health, psychological health, social relations, and the living environment, especially for people affected by floods.

Is Social Support Associated with Colorectal Cancer Care Utilization? A Multilevel Mixed-Effects Model of a Cross-Sectional Cohort Study in Vietnam.

OBJECTIVE: To investigate the relationship between the social support (SS) and colorectal cancer (CRC) care utilization of patients in the central region of Vietnam. METHODS: This was a cross-sectional cohort study in which the cohort was defined as all residential patients diagnosed with CRC in a tertiary hospital, Hue Central Hospital (HCH), in central Vietnam from 2013 to 2019. Social support was considered the main independent variable and was evaluated using the Medical Outcomes Study Social Support Survey (MOS-SSS), a self-administered 19-item SS survey. MOS-SSS is a widely used scale for assessing social support in CRC patients because it is brief, easy to use, reliable, and valid. In this study, we considered a data framework with a multilevel structure that included the patient level and duration of diagnosis as the second level. We estimated the magnitude of SS and CRC-specific treatment modalities using multilevel mixed-effects (MM) models under a hierarchical approach. RESULTS: The findings indicated that CRC care utilization rates were 89.9%, 48.5%, and 30.6% for surgical resection, chemotherapy, and radiation therapy, respectively. The overall trend of SS decreased significantly and affected the CRC care utilization. We found a positive effects of overall SS, as well as emotional and tangible support, on the number of hospitalization admissions and chemotherapy utilization. CONCLUSION: This study suggests that the use of the MOS-SSS should be continued in the long term for CRC patients to enhance medical accessibility and care utilization.

Quality of Life and Factors Affecting It: A Study Among People Living Near a Solid Waste Management Facility.

Background: The amount of waste generated has been increasing over the years. Meanwhile, the capacity of solid waste management facilities (SWMFs) for waste disposal does not meet the needs, resulting in adverse consequences on the natural environment and health of residents living near these plants, which can significantly degrade their quality of life (QoL). This study aims to evaluate the QoL of residents living near an SWMF and the potential impacts it has on the residents. Methods: A cross-sectional descriptive study was conducted involving 801 subjects, aged 18 and above, who live near the SWMF of Hue City, Vietnam. The QoL of the subjects was quantitatively assessed using the WHO QoL assessment scale (WHOQOL-BREF). The general, health, and environmental factors influencing QoL were identified using bivariate and multivariate logistic regression analyses. Results: About 22.6% of the subjects had a good QoL. In particular, the proportions for good psychological health (6.9%) and environment (13.6%) were low, indicating an influence of the SWMF. Significant factors that degraded the QoL of residents were less education defined by not graduating from high school (odds ratio, OR = 2.78; 95% CI = 1.09-7.06), poor health status (OR = 2.50; 95% CI: 1.56-4.01), dissatisfaction with water quality (OR = 2.41; 95% CI: 1.10-5.25), and unacceptance of the SWMF presence (OR = 1.70; 95% CI: 1.11-2.60). Moreover, subjects living within 2 km of the plant had dermatological diseases and digestive disorders more frequently than those who lived away from the plant. They also reported more complaints regarding water, air, and soil quality, which were likely due to the operation of the SWMF. Conclusions: Burying and disposing of solid waste at the SWMF might lead to the degradation of the surrounding water and soil environments, and its collection and transportation are considered to cause odor and dust. The efforts of responsible authorities to strictly supervise and inspect these activities at the SWMF are essential, not only to protect the surrounding environment but also to improve the QoL of those who live nearby these plants.

Weekly Variation of Rotavirus A Concentrations in Sewage and Oysters in Japan, 2014-2016.

Concentrations of rotavirus A, in sewage and oysters collected weekly from September 2014 to April 2016 in Japan, were investigated using RT-qPCR; results showed up to 6.5 log10 copies/mL and 4.3 log10 copies/g of digestive tissue (DT) in sewage and oysters, respectively. No correlation was found between rotavirus concentration in sewage and oysters and cases of rotavirus-associated gastroenteritis.

Hope for the Best, Prepare for the Worst-An Assessment of Flood Preparedness at Primary Health Care Facilities in Central Vietnam.

Background: Floods affect over 85 million people every year and are one of the deadliest types of natural disasters. The health effects of floods are partly due to a loss of access to health care. This loss can be limited with proper flood preparedness. Flood preparedness is especially needed at the primary health care (PHC) level. Flood preparedness assessments can be used to identify vulnerable facilities and help target efforts. The existing research on PHC flood preparedness is limited. We aimed to assess the flood preparedness of PHC facilities in a flood-prone province in central Vietnam. Methods: Based on flood experience, the PHC facilities in the province were grouped as "severe" (n = 23) or "non-severe" (n = 129). Assessments were conducted during monsoon season at five facilities from each group, using a pre-tested, semi-structured questionnaire. Data were checked against official records when possible. Results: Nine of the ten facilities had a flood plan and four received regular flood preparedness training. Six facilities reported insufficient preparedness support. Half of the facilities had additional funding available for flood preparedness, or in case of a flood. Flood preparedness training had been received by 21/28 (75%) of the staff at the facilities with severe flood experience, versus 15/25 (52%) of the staff at the non-severe experience facilities. Conclusions: Our results suggest that the assessed PHC facilities were not sufficiently prepared for the expected floods during monsoon season. PHC flood preparedness assessments could be used to identify vulnerable facilities and populations in flood-prone areas. More research is needed to further develop and test the validity and reliability of the questionnaire.

Oyster Contamination with Human Noroviruses Impacted by Urban Drainage and Seasonal Flooding in Vietnam.

This study investigated the level of norovirus contamination in oysters collected at a lagoon receiving urban drainage from Hue City for 17 months (August 2015-December 2016). We also investigated the genetic diversity of norovirus GI and GII in oyster and wastewater samples by using pyrosequencing to evaluate the effect of urban drainage on norovirus contamination of oysters. A total of 34 oyster samples were collected at two sampling sites (stations A and B) in a lagoon. Norovirus GI was more frequently detected than GII (positive rate 79 vs. 41%). Maximum concentrations of GI and GII were 2.4 × 105 and 2.3 × 104 copies/g, respectively. Co-contamination with GI and GII was observed in 35% of samples. Norovirus GII concentration was higher at station A in the flood season than in the dry season (P = 0.04, Wilcoxon signed-rank test). Six genotypes (GI.2, GI.3, GI.5, GII.2, GII.3, and GII.4) were identified in both wastewater and oyster samples, and genetically similar or identical sequences were obtained from the two types of samples. These observations suggest that urban drainage and seasonal flooding contribute to norovirus contamination of oysters in the study area.

A systematic review and meta-analysis of the prevalence of norovirus in cases of gastroenteritis in developing countries.

BACKGROUND: While norovirus (NoV) is well known as a leading causal pathogen for acute gastroenteritis in developed countries,structured data on prevalence in developing countries are not available thus far. This review aims to estimate the prevalence of NoV in cases of gastroenteritis in developing countries based on recently published reports. METHODS: Relevant studies were identified by searching PubMed and Web of Science for the period January 1, 1990 through March 31, 2016. We included studies performed in developing countries with a study period of at least 12 months and which provided information on polymerase chain reaction (PCR)-confirmed NoV prevalence in patients diagnosed with acute gastroenteritis. A metaanalysis was conducted on NoV prevalence, focused on viral genogroups GI and GII, in cases of acute gastroenteritis. RESULTS: Using evidence from 178 articles, the estimated NoV prevalence among 148,867 patients with acute gastroenteritis was 17% (95% confidence interval [CI]: 15-18%). The prevalence decreased from 18% (95% CI: 16-20%) for upper middle-income countries to 15% (13-18%) and 6% (3-10%) for lower middle- and low-income countries, respectively. There were no significant differences in NoV prevalence by age group (under 5 years, 5 years and over, and mixed ages) or severity of symptoms as defined by community, outpatient, or inpatient setting. The pooled prevalence of NoV GII (15%, 95% CI: 13-17%) was significantly higher than that of NoV GI (1%, 95% CI: 1-1%) in patients with acute gastroenteritis. CONCLUSION: From the evidence considered in this review, the estimated prevalence of NoV in patients with acute gastroenteritis in developing countries was 17%. This estimate can be used to evaluate the burden of NoV-associated acute gastroenteritis in developing countries, which is currently unclear due to poor diagnosis and surveillance systems, and the estimation may enhance the development of human NoV vaccines.
