Summary: Southeast Asia is facing a significant increase in energy consumption and environmental issues, with a largely untapped potential lying in residual biomass. Research in Vietnam reveals high production quantities and energy yields of agricultural byproducts, particularly rice straw and husks, sugarcane bagasse, and trash. The Mekong River Delta region stands out as a primary source of rice biomass, while central regions of Vietnam are key areas for sugarcane byproducts. Furthermore, detailed laboratory analysis of fuel-energy properties of these materials has been conducted to explore the possibilities of biofuel production and energy utilization.

Summary: This study aimed to provide a comprehensive overview of fear of falling (FOF) among older adults in Southeast Asia, including its prevalence, measurement scales, related factors, and interventions. A total of 15 observational studies and three experimental studies conducted in Malaysia, Singapore, Thailand, and Vietnam were included. The FOF prevalence ranged from 21.6% to 88.2%, and common related factors included female sex, advanced age, balance impairment, and fall history. The interventions mainly focused on exercise, but limited attention was given to environmental factors.

Summary: Over the 10-year study period, there were no significant differences in the bacterial etiology of community-acquired pneumonia (CAP), but there was a decline in septic complications such as septic shock, bacteremia, and complicated pleural effusion. Influenza vaccination played an important role in reducing mortality.

Summary: Testing is crucial in containing the SARS-CoV-2 pandemic. Nasopharyngeal samples are most effective for sensitivity detection, and current swab processing involves diluting patient samples. Future testing optimization should focus on using smaller volumes of viral transport media and improving swab designs for increased comfort and viral adhesion.

Summary: The clinical utility of the BioFire FilmArray Pneumonia Panel Plus (BFPP) in diagnosing hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) was evaluated. The BFPP showed excellent diagnostic sensitivity, but limitations were observed in detecting antimicrobial resistance (AMR) genes and certain bacteria.

Summary: This study identified the etiology of community acquired pneumonia (CAP) in adult patients, with Streptococcus pneumoniae, gram-negative bacilli, and Legionella pneumophila being common pathogens. Combining blood and sputum cultures with urinary antigen tests significantly improved diagnostic performance. Patient demographics and clinical features such as age, smoking status, and pre-existing respiratory diseases were found to influence the likelihood of specific CAP causative agents.

Summary: This prospective study in China evaluated the use of multiple pathogen detection methods in patients with severe community acquired pneumonia (SCAP) and assessed their impact on clinical outcomes. The results showed that early combined detection improved the identification rate of pathogens and may have benefited survival. Influenza virus, S pneumoniae, and Enterobacteriaceae were identified as the leading causes of SCAP in China.

Summary: This study evaluated the clinical application of nested multiplex polymerase chain reaction (PCR) in children with severe community-acquired pneumonia (CAP) and found that it could accurately diagnose the pathogens. The combination of nested multiplex PCR and standard-of-care tests could detect at least one pathogen in 98% of severe CAP cases. This study is of great importance for early diagnosis and treatment of severe CAP in pediatric patients.

Summary: There was a prolonged lockdown and reduction in human activities during the Covid-19 pandemic period, which led to a significant reduction in land surface temperatures in Ho Chi Minh City, Vietnam. This reduction was in agreement with the decrease in greenhouse gases observed during the same period. However, the land surface temperatures have increased since the lifting of the lockdown measures in November 2021.

Summary: This study aimed to determine and characterize the aetiology of Community-acquired pneumonia (CAP) in hospitalized adults through the analysis of respiratory and blood samples using Multiplex Real-Time PCR/RT-PCR and ID/AMR enrichment panel (RPIP). The most prevalent viral pathogens detected were influenza A, SARS-CoV-2, and human rhinovirus, while the most common bacterial pathogens detected were Streptococcus pneumoniae, Staphylococcus aureus, and Haemophilus influenzae. Antimicrobial resistance genes were identified in 23 patients, with S. aureus being the most common AMR correlated strain.

Summary: This retrospective study aimed to assess the characteristics and outcomes of community-acquired pneumonia (CAP) in kidney transplant recipients in France. The findings showed that more than one-third of CAP episodes in these patients were caused by identified microorganisms, including drug-resistant and opportunistic pathogens. Some patients required intensive care and mechanical ventilation.

Summary: Nonpharmaceutical interventions (NPIs) for COVID-19 have a significant impact on the activity of respiratory syncytial virus infections (RSV), leading to a decline in RSV transmission. However, prolonged NPIs may increase the susceptible population and enhance the risk of large-scale RSV outbreaks.

Summary: In the COVE phase 3 clinical trial, neutralizing and binding antibodies were measured in vaccine recipients to determine their correlation with COVID-19 risk and vaccine efficacy. The results showed that these immune markers were inversely associated with COVID-19 risk and directly associated with vaccine efficacy. Postvaccination neutralization titers of 10, 100, and 1000 correlated with estimated vaccine efficacies of 78%, 91%, and 96% respectively.

Summary: This study found that multiple serotypes of pneumococci are common among adults with pneumonia. The risk of multiple-serotype pneumococcal pneumonia is lower in patients vaccinated with PPSV23. Certain specific serotypes are associated with multiple-serotype pneumonia, and more invasive serotypes are more prevalent in multiple-serotype pneumonia.

Summary: This study aimed to determine the epidemiological aspects, drug resistance patterns, and genetic elements of V. cholerae O1 strains isolated from two cholera epidemics in Kenya. The majority of isolates were resistant to trimethoprim-sulfamethoxazole, streptomycin, and nalidixic acid, and the integrating conjugative (SXT) element was found in most isolates. The 2015-2016 epidemic strains were found susceptible to most antibiotics except nalidixic acid.

Summary: The study developed a method called RT-LAMP-BART to detect the mutations N501Y and Q493R/Q498R in the SARS-CoV-2 spike protein. Compared to conventional real-time RT-PCR, the RT-LAMP-BART assay was more specific and sensitive, able to detect lower copies of the target genes in a shorter time. This new assay has the potential to aid in the identification of concerning SARS-CoV-2 variants.

Summary: A study conducted in Nha Trang, Vietnam, found that Streptococcus pneumoniae is the main cause of high pneumonia morbidity and mortality in children. The study showed that children attending school and older children were more likely to be infected with S. pneumoniae. The study also identified common serotypes and high resistance to certain antibiotics, as well as a high genetic diversity among the isolates.

Summary: In 2019, a community-based investigation was conducted in rural Vietnam to study the mechanism of diphtheria outbreaks. The study found a carriage prevalence of 1.4% and identified 27 asymptomatic carriers, some of whom carried toxigenic strains. Child malnutrition was associated with low levels of diphtheria toxoid IgG, which might have increased child carriage prevalence. The study recommended a school-entry booster dose and improved infant vaccination coverage to control transmissions.

Summary: Antibiotic use and misuse remain a worldwide concern, with concerns about antimicrobial resistance, lack of new antibiotics, and rising healthcare costs. This study compared two theoretical models (health belief and patient-centered communication) to determine which best represented pathways associated with antibiotic use, finding that a patient-provider communication model fit the data better. Participants had mixed knowledge about antibiotics, with many knowing correct general facts but a significant portion believing antibiotics cure colds and flu or are good for treating viral infections.
