Abstract
BACKGROUND The COVID-19 pandemic has underscored the significance of adopting healthy lifestyles to mitigate the risk of severe outcomes and long-term consequences. OBJECTIVE This study focuses on assessing the prevalence and clustering of 5 unhealthy lifestyle behaviors among Vietnamese adults after recovering from COVID-19, with a specific emphasis on sex differences. METHODS The cross-sectional data of 5890 survivors of COVID-19 in Vietnam were analyzed from December 2021 to October 2022. To examine the sex differences in 5 unhealthy lifestyle behaviors (smoking, drinking, unhealthy diet, physical inactivity, and sedentary behavior), the percentages were plotted along with their corresponding 95% CI for each behavior. Latent class analysis was used to identify 2 distinct classes of individuals based on the clustering of these behaviors: the "less unhealthy" group and the "more unhealthy" group. We examined the sociodemographic characteristics associated with each identified class and used logistic regression to investigate the factors related to the "more unhealthy" group. RESULTS The majority of individuals (male participants: 2432/2447, 99.4% and female participants: 3411/3443, 99.1%) exhibited at least 1 unhealthy behavior, with male participants being more susceptible to multiple unhealthy behaviors. The male-to-female ratio for having a single behavior was 1.003, but it escalated to 25 for individuals displaying all 5 behaviors. Male participants demonstrated a higher prevalence of combining alcohol intake with sedentary behavior (949/2447, 38.8%) or an unhealthy diet (861/2447, 35.2%), whereas female participants tended to exhibit physical inactivity combined with sedentary behavior (1305/3443, 37.9%) or an unhealthy diet (1260/3443, 36.6%). Married male participants had increased odds of falling into the "more unhealthy" group compared to their single counterparts (odds ratio [OR] 1.45, 95% CI 1.14-1.85), while female participants exhibited lower odds (OR 0.65, 95% CI 0.51-0.83). Female participants who are underweight showed a higher likelihood of belonging to the "more unhealthy" group (OR 1.11, 95% CI 0.89-1.39), but this was not observed among male participants (OR 0.6, 95% CI 0.41-0.89). In both sexes, older age, dependent employment, high education, and obesity were associated with higher odds of being in the "more unhealthy" group. CONCLUSIONS The study identified notable sex differences in unhealthy lifestyle behaviors among survivors of COVID-19. Male survivors are more likely to engage in unhealthy behaviors compared to female survivors. These findings emphasize the importance of tailored public health interventions targeting sex-specific unhealthy behaviors. Specifically, addressing unhealthy habits is crucial for promoting post-COVID-19 health and well-being.

Abstract
From May to September 2013, monthly samples were collected from swine in a Vietnamese slaughterhouse for influenza virus isolation and serological testing. A(H1N1)pdm09 viruses and a novel H3N2 originating from reassortment between A(H1N1)pdm09 and novel viruses of the North American triple reassortant lineage were isolated. Serological results showed low seroprevalence for the novel H3N2 virus and higher seroprevalence for A(H1N1)pdm09 viruses. In addition, serology suggested that other swine influenza viruses are also circulating in Vietnamese swine.

Abstract
Decoration of noble metal nanoparticles (NPs) on the surface of semiconducting metal oxide nanowires (NWs) to enhance material characteristics, functionalization, and sensing abilities has attracted increasing interests from researchers worldwide. In this study, we introduce an effective method for the decoration of Pd NPs on the surface of SnO2 NWs to enhance CO gas-sensing performance. Single-crystal SnO2 NWs were fabricated by chemical vapor deposition, whereas Pd NPs were decorated on the surface of SnO2 NWs by in situ reduction of the Pd complex at room temperature without using any linker or reduction agent excepting the copolymer P123. The materials were characterized by advanced techniques, such as high-resolution transmission electron microscopy, scanning transmission electron microscopy, and energy-dispersive X-ray spectroscopy. The Pd NPs were effectively decorated on the surface of SnO2 NWs. As an example, the CO sensing characteristics of SnO2 NWs decorated with Pd NPs were investigated at different temperatures. Results revealed that the gas sensor exhibited excellent sensing performance to CO at low concentration (1-25ppm) with ultrafast response-recovery time (in seconds), high responsivity, good stability, and reproducibility.

Abstract
In this paper, a new method for permeability measurement of hydrophobic membranes used in Vacuum Membrane Distillation, instead of common measurement methods, was proposed. As VMD is a pressure and temperature driven process, the idea of this work is to propose a new water vapour permeability measurement method based on variation of feed temperature at a fixed vacuum pressure. This new method showed a greater stability and simplicity than the existing pressure variation method by not only allowing a wide range of feed temperature (25 °C ÷ 60 °C) to be scanned continuously, but also avoiding fluctuations of the system as observed in the pressure variation test. Permeabilities of two different kinds of hydrophobic membranes were measured by this new method and also by the existing pressure variation test. A comparison between these two methods was also presented to assess the feasibility and applicability of this new method.

Abstract
A model for cost-benefit analysis and cost-effectiveness analysis (CBA-CEA) of pharmaceutical intervention is presented, and CBA-CEA research methods reported in the literature are reviewed. The cost versus benefit and the cost effectiveness of drug therapy can be analyzed in societal as well as private terms. Since CBA measures costs and outcomes in monetary terms, it can be used to compare net benefits of all types of interventions. CEA, however, can be used only in comparing alternative interventions that can produce a similar health outcome. Research activities needed for identification of treatment protocols, alternative therapies and their respective outcomes, and resource use are described. Quantification of benefits and costs is discussed and inherent strengths and weaknesses of CBA-CEA are summarized. For the wide variety of research activities involved in CBA-CEA, the expertise of economists, physicians, clinical pharmacists and pharmacologists, epidemiologists, sociologists, and psychologists is needed. Inherent in CBA-CEA for drug therapy are judgments, either by analysts or by policy decision makers, about how to value life, pain, anxiety, and happiness and how to distribute health-care resources. When results of CBA-CEA are presented and interpreted with care, this analysis can be an important tool for policy decision makers.
