Progression of liver fibrosis and associated factors among chronic hepatitis B patients at a general hospital in Northern Vietnam.

Evaluation of liver fibrosis is necessary to make the therapeutic decision and assess the prognosis of CHB patients. The current study aimed to describe the progression and identify some influencing factors in patients with chronic hepatitis B at a General Hospital in Northern Vietnam. The longitudinal study included 55 eligible subjects diagnosed Hepatitis-B-virus. Dependent variable was the aspartate aminotransferase/platelet ratio index and we collected some demographic variables and disease related and behaviour variables. Bayesian Model Averaging was used to select variables into model. Mixed-effect linear models were used to evaluate the change of the aspartate aminotransferase/platelet ratio index over time and identify related factors. the aspartate aminotransferase/platelet ratio index differences between examinations, age of participants, working status were statistically significant. This pattern indicated that the average the aspartate aminotransferase/platelet ratio index of the population decreased by 0.005 (95% CI=-0.009; -0.001) after each patient's visit, and increased by 0.013 if the patient's age increased by 1 year (95% CI=0.005; 0.0219). For non-working patients, the aspartate aminotransferase/platelet ratio index was lower, coefficient was -0.054 (95% CI=-0.108; 0.001). Other variables such as gender, education level, time for disease detection, drinking tea, alcohol consumption, forgetting to take medicine and the aspartate aminotransferase/platelet ratio index were not significantly different. The study showed that the majority of study subjects had average the aspartate aminotransferase/platelet ratio index, and were relatively well controlled and treated during the study. Age and working status are factors that influence the the aspartate aminotransferase/platelet ratio index.

Exercise and Quality of Life in Women with Menopausal Symptoms: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Menopausal symptoms are associated with deterioration in physical, mental, and sexual health, lowering women's quality of life (QoL). Our study objective is to examine the effect of exercise on QoL in women with menopausal symptoms. After initially identifying 1306 studies published on PubMed, Web of Science, Scopus, and Cochrane Library before June 2020, two researchers independently selected nine randomized controlled trials (RCTs) in which any type of exercise was compared with no active treatment. We assessed the risk of bias in the included studies using the Cochrane risk-of-bias 2.0 tool for RCTs and computed the converged standardized mean difference with a 95% confidence interval. We found evidences for the positive effects of exercise on physical and psychological QoL scores in women with menopausal symptoms. However, there was no evidence for the effects of exercise on general, social, and menopause-specific QoL scores. The most common interventions for women with menopausal and urinary symptoms were yoga and pelvic floor muscle training (PFMT), respectively. In our meta-analyses, while yoga significantly improved physical QoL, its effects on general, psychological, sexual, and vasomotor symptoms QoL scores as well as the effect of PFMT on general QoL were not significant. Our findings suggest that well-designed studies are needed to confirm the effect of exercise on QoL in women with menopausal symptoms.

Climatic-driven seasonality of emerging dengue fever in Hanoi, Vietnam.

BACKGROUND: Dengue fever (DF) has been emerging in Hanoi over the last decade. Both DF epidemiology and climate in Hanoi are strongly seasonal. This study aims at characterizing the seasonality of DF in Hanoi and its links to climatic variables as DF incidence increases from year to year. METHODS: Clinical suspected cases of DF from the 14 central districts of Hanoi were obtained from the Ministry of Health over a 8-year period (2002-2009). Wavelet decompositions were used to characterize the main periodic cycles of DF and climatic variables as well as the mean phase angles of these cycles. Cross-wavelet spectra between DF and each climatic variables were also computed. DF reproductive ratio was calculated from Soper's formula and smoothed to highlight both its long-term trend and seasonality. RESULTS: Temperature, rainfall, and vapor pressure show strong seasonality. DF and relative humidity show both strong seasonality and a sub-annual periodicity. DF reproductive ratio is increasing through time and displays two clear peaks per year, reflecting the sub-annual periodicity of DF incidence. Temperature, rainfall and vapor pressure lead DF incidence by a lag of 8-10 weeks, constant through time. Relative humidity leads DF by a constant lag of 18 weeks for the annual cycle and a lag decreasing from 14 to 5 weeks for the sub-annual cycle. CONCLUSION: Results are interpreted in terms of mosquito population dynamics and immunological interactions between the different dengue serotypes in the human compartment. Given its important population size, its strong seasonality and its dengue emergence, Hanoi offers an ideal natural experiment to test hypotheses on dengue serotypes interactions, knowledge of prime importance for vaccine development.

Counselling-A necessary task for the obstetrician when a fetus suffers from a congenital malformation

Counselling for women during pregnancy is an important part of the obstetrician's tasks. When the patient is a pregnant woman whose fetus is found through ultrasound scanning to suffer from a congenital malformation, counselling becomes even more important. Objective: The objectives of this article are to explore women's perceptions of the ultrasound scanning and their satisfaction with the doctor's advice and investigate the factors affectted to the quality of counseling. Method: The research was conducted in Hanoi Obstetric Hosital, using participant observation and in-depth interviews with women pregnant with an anomalous fetus. Result: The research documents that women are not always satisfied with the counselling provided. Several factors affect the quality of counseling, notably the lack of trained health staff and the overload of work at the hospital. Conclusion: The article concludes that the counselling provided does not live up to women's expectations and that this has to do with the qualifications of health staff and the organization of hospital services. On the basis of the research, some recommendations are proposed in order to improve the quality of counselling, diagnosis and decision-making when a fetal malformation occurs
