RESUMO
BACKGROUND: One hundred days after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported in Vietnam on 23 January, 270 cases were confirmed, with no deaths. We describe the control measures used by the government and their relationship with imported and domestically acquired case numbers, with the aim of identifying the measures associated with successful SARS-CoV-2 control. METHODS: Clinical and demographic data on the first 270 SARS-CoV-2 infected cases and the timing and nature of government control measures, including numbers of tests and quarantined individuals, were analyzed. Apple and Google mobility data provided proxies for population movement. Serial intervals were calculated from 33 infector-infectee pairs and used to estimate the proportion of presymptomatic transmission events and time-varying reproduction numbers. RESULTS: A national lockdown was implemented between 1 and 22 April. Around 200 000 people were quarantined and 266 122 reverse transcription polymerase chain reaction (RT-PCR) tests conducted. Population mobility decreased progressively before lockdown. In total, 60% (163/270) of cases were imported; 43% (89/208) of resolved infections remained asymptomatic for the duration of infection. The serial interval was 3.24 days, and 27.5% (95% confidence interval [CI], 15.7%-40.0%) of transmissions occurred presymptomatically. Limited transmission amounted to a maximum reproduction number of 1.15 (95% CI, .·37-2.·36). No community transmission has been detected since 15 April. CONCLUSIONS: Vietnam has controlled SARS-CoV-2 spread through the early introduction of mass communication, meticulous contact tracing with strict quarantine, and international travel restrictions. The value of these interventions is supported by the high proportion of asymptomatic and imported cases, and evidence for substantial presymptomatic transmission.

To assess the role of in-flight transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we investigated a cluster of cases among passengers on a 10-hour commercial flight. Affected persons were passengers, crew, and their close contacts. We traced 217 passengers and crew to their final destinations and interviewed, tested, and quarantined them. Among the 16 persons in whom SARS-CoV-2 infection was detected, 12 (75%) were passengers seated in business class along with the only symptomatic person (attack rate 62%). Seating proximity was strongly associated with increased infection risk (risk ratio 7.3, 95% CI 1.2-46.2). We found no strong evidence supporting alternative transmission scenarios. In-flight transmission that probably originated from 1 symptomatic passenger caused a large cluster of cases during a long flight. Guidelines for preventing SARS-CoV-2 infection among air passengers should consider individual passengers' risk for infection, the number of passengers traveling, and flight duration.

A hospital-based, case-control study was conducted to investigate the association between lifestyle patterns and risk of colorectal cancer (CRC) in the north of Vietnam. Demographic factors employed for the models were age, sex, marital status, occupation, education, income, smoking status, alcohol consumption, vegetable consumption, tea, coffee consumption, and physical activity (PA). Individuals of both groups (n = 154 for the control group and n = 136 for the CRC group) were interviewed using a questionnaire by trained interviewers. The findings showed that moderate PA was inversely associated with CRC risk: odds ratio (OR) = 0.19, 95% confidence interval (CI) = 0.10 to 0.36 with P < .01. The total PA showed that the highest tertile (>2.7 MET-h/d) was associated with the reduced risk of CRC compared with the lowest tertile one after controlling for confounding factors: adjusted OR = 0.25, 95% CI = 0.09 to 0.74, P < .01. Sedentary time was associated with an increased level of CRC risk by 57% as compared between the highest tertile and the lowest one after controlling for confounding factors. Daily consumption of vegetables and 1 to 3 cups of tea per day or more were also associated with decreased risk of CRC. Despite promising findings, a limitation of this research is that it did not establish a temporal relationship between risk factors and CRC due to its retrospective design. However, this is the first analytic study highlighting the role of the active lifestyle pattern associated with reduced CRC risk in Vietnamese adults.

BACKGROUND: Globally, fall-related injuries are a substantial problem, and 80% of fatal falls occur in low-income and middle-income countries. We aimed to measure time from injury to hip-fracture surgery in people aged 50 years or older living in low-income and middle-income regions, as well as to measure the proportion of patients with surgical stabilisation of their hip fracture within 72 h of admission to hospital and to identify risk factors associated with surgical delay. METHODS: For this secondary analysis, we analysed data collected from Africa, Latin America, China, India, and Asia (excluding China and India) for the International Orthopaedic Multicentre Study in Fracture Care (INORMUS) between March 29, 2014, and June 15, 2022. Patients from INORMUS were included in this analysis if they were aged 50 years or older and had an isolated, primary hip fracture sustained from a ground-level fall. Staff at participating hospitals identified patients with musculoskeletal injury and referred them for assessment of eligibility. We report time from injury to surgery as three distinct time periods: time from injury to hospital admission, time from admission to surgery, and a total time from injury to surgery. Date and time of injury were self-reported by patients at the time of study recruitment. If time to hospital admission after injury exceeded 24 h, patients reported the primary reason for delayed admission. Reasons for surgery, no surgery, and surgical delay were reported by the treating team. For patients undergoing surgery, multivariable regression analyses were used to identify risk factors for surgical delay. FINDINGS: 4486 adults aged 50 years or older with an isolated, primary hip fracture were enrolled in INORMUS from 55 hospitals in 24 countries. Countries were grouped into five regions: Africa (418 [9·3%] of 4486), Latin America (558 [12·4%]), China (1680 [37·4%]), India (1059 [23·6%]) and Asia (excluding China and India; 771 [17·2%]). Of 4486 patients, 3805 (84·8%) received surgery. The rate of surgery was similar in all regions except in Africa, where only 193 (46·3%) of 418 patients had surgery. Overall, 2791 (62·2%) of 4486 patients were admitted to hospital within 24 h of injury. However, 1019 (22·7%) of 4486 patients had delayed hospital admission of 72 h or more from injury. The two most common reasons for delayed admission of more than 24 h were transfer from another hospital (522 [36·2%] of 1441) and delayed care-seeking because patients thought the injury would heal on its own (480 [33·3%]). Once admitted to hospital, 1451 (38·1%) of 3805 patients who received surgery did so within 72 h (median 4·0 days [IQR 1·7-6·0]). Regional variation was seen in the proportion of patients receiving surgery within 72 h of hospital admission (92 [17·9%] of 514 in Latin America, 53 [27·5%] of 193 in Africa, 454 [30·9%] of 1471 in China, 318 [44·4%] of 716 in Asia [excluding China and India], and 534 [58·6%] of 911 in India). Of all 3805 patients who received operative treatment, 2353 (61·8%) waited 72 h or more from hospital admission. From time of injury, the proportion of patients who were surgically stabilised within 72 h was 889 (23·4%) of 3805 (50 [9·7%] of 517 in Latin America, 31 [16·1%] of 193 in Africa, 277 [18·8%] of 1471 in China, 189 [26·4%] of 716 in Asia [excluding China and India], and 342 [37·5%] of 911 in India). INTERPRETATION: Access to surgery within 72 h of hospital admission was poor, with factors that affected time to surgery varying by region. Data are necessary to understand existing pathways of hip-fracture care to inform the local development of quality-improvement initiatives.

Surgical antibiotic prophylaxis (SAP) is considered an important interventional tool for antimicrobial resistance. Guideline compliance was poor across different countries and this results in an inappropriate and overuse of antibiotics. The study was cross-sectional, combining qualitative and quantitative. The Research used the MOH's Antibiotic Preventive Medicine Guidelines as the standard to verify surgical preventive treatment compliance from patient medical records. Research performed on 373 medical records with surgical indications. The study was conducted from January to June 2019. Data were entered using Epidata software and processed by SPSS software version 19.0. Analysis: calculating OR for related factors. The compliance rate of using prophylactic antibiotics was 83.1%. There is a relationship between the type of incision, the length of time surgery, and compliance with surgical prophylactic use of antibiotics (P < .05). Barriers to adherence to prophylactic antimicrobial therapy include: overcrowding patients, health-care workers "broad-spectrum antibiotic use habits, and health-care workers" views on surgical and muscle environment, the material was not completely sterilized.
RESUMO
The disease caused by the SARS-Cov 2 virus has spread to most areas of the world with high rates of infection and deaths. Facing the complicated developments of the epidemic, clinical medical staff (CMS) are at risk of suffering psychological pressure. This study aimed to investigate the situation of anxiety, depression, and related factors affecting CMS during the COVID-19 pandemic at Dong Da General Hospital and Dong Anh General Hospital in Hanoi. A cross-sectional study was conducted from April to July 2020 using self-administered questionnaires amongst 341 CMS. The participants' anxiety levels were assessed using the standardized General Anxiety Disorder-7 (GAD-7) toolkit and levels of depression expression were assessed based on the standardized Patient Health Questionnaire-9 (PHQ-9) toolkit. Of the CMS who completed the questionnaire, 33.1% had an anxiety disorder and 23.2% exhibited mild to very severe depression. The factors associated with anxiety and depression were department of work, shortage of human resources, and discrimination from the community that directly affects the family of the CMS. The study results highlight the need for a training session to equip CMS with the skills required to cope with psychological stress in all circumstances in general and during the pandemic in particular. This training is especially important for those working in at-risk departments which are susceptible to infection.

OBJECTIVE: Viet Nam is experiencing a shift in its burden of disease profile with injuries becoming more prominent. A history of high alcohol involvement in road traffic crashes despite stringent laws led to increased enforcement by police, enhanced public education messaging and targeted social marketing campaigns in Ha Nam and Ninh Binh provinces in Viet Nam. This study aims to illustrate the changes in prevalence (November 2010 to December 2011) and knowledge, attitudes and practices (KAP) around alcohol use and drink-driving for the year 2011. METHODS: Breath Alcohol Concentration (BrAC) was collected through police enforcement checkpoints in the two provinces. The proportion of drivers with BrAC above the legal limit was plotted over time for both provinces. The trend in prevalence of drink-driving over time was further assessed using Poisson regression models. Prevailing KAPs were determined through surveying randomly selected road users over the age of 17 years at gas stations at quarterly intervals. Cross tabulations of key variables as well Chi-Square statistic were used to assess associations. RESULTS: A total of 8,404 drivers were tested for BrAC levels of which less than 0.25% were female. Of 1,639 drivers displaying BrAC levels in excess of the legal limit, 87.3% were car drivers, 7.9% motorcyclists and 86% were between the ages of 25 and 44 years. KAP surveys captured 1,661 drivers over the study period. The prevalence of self-reported drink-driving increased 6 percentage points among respondents aged 27-36. Between 44% (January 2011) and 49% (December 2011) of respondents indicated awareness of a drinking and driving Blood Alcohol Concentration (BAC) or BrAC limit and only 25% of all study participants recalled being penalized for a traffic violation - none of which were for drink-driving. CONCLUSION: While there has been some reduction in drink-driving prevalence, inadequate or incorrect knowledge on drink-driving legislation appears to be an impediment to greater gains. Increased attention needs to be paid to enforcement activities and social marketing campaigns need to be part of a multi-faceted programme that also works on improving existing legislation, takes into consideration gender issues, and enhances visible enforcement of the laws.

BACKGROUND: Vietnam is one of the most disaster-prone countries in the world. The country suffers from many kinds of natural disasters, of which the most common and serious one is flooding. Long and heavy rainfall during the last days of October and the first week of November 2008 resulted in a devastating flood unseen for over three decades in the capital city of Hanoi. It caused a substantial health impact on residents in and around the city and compromised the capacity of local health services. OBJECTIVE: The aim of this study is to ascertain the vulnerability and health impacts of the devastating flood in Hanoi by identifying the differences in mortality, injuries, and morbidity patterns (dengue, pink eye, dermatitis, psychological problems, and hypertension) between flood affected and non-affected households. DESIGN: A cross-sectional study was carried out involving 871 households in four selected communes (two heavily flood affected and two comparatively less affected) from two severely flooded districts of Hanoi. Participants were interviewed and information collected on the social, economic, and health impacts of the devastation within 1 month after the flood. RESULTS: The self-reported number of deaths and injuries reported in this study within 1 month after the heavy rainfall were a bit higher in severely affected communes as compared to that of the less affected communes of our study. The findings showed higher incidences of dengue fever, pink eye, dermatitis, and psychological problems in communes severely affected by flood as compared to that of the controlled communes. CONCLUSIONS: For people in flood prone areas (at risk for flooding), flood prevention and mitigation strategies need to be seriously thought through and acted upon, as these people are exposed to greater health problems such as psychological issues and communicable diseases such as pink eye or dermatitis.

Since 1997, the largest epidemic of highly pathogenic avian influenza (H5N1) ever recorded has caused 172 human and several billion bird deaths. Recently administered questionnaires determined that live poultry exposures have declined by approximately 63% in Hong Kong since 2004 and that, in Vietnam, domestic backyard exposures to poultry are likely more important than retail exposures.
