Objectives: The objective of this study was to characterize mental health issues among Vietnamese healthcare workers (HCWs) and to identify related factors., Methods: A cross-sectional study was conducted with 990 HCWs in 2021. Their mental health status was measured using the Depression, Anxiety, and Stress Scale., Results: In total, 49.9%, 52.3%, and 29.8% of respondents were found to have depression, anxiety, and stress, respectively. The multivariable linear regression model revealed that factors associated with increased anxiety scores included depression scores (β, 0.45; 95% confidence interval [CI], 0.39 to 0.51) and stress scores (β, 0.46; 95% CI, 0.41 to 0.52). Factors associated with increased depression scores included being frontline HCWs (β, 0.57; 95% CI, 0.10 to 1.10), stress scores (β, 0.50; 95% CI, 0.45 to 0.56), and anxiety scores (β, 0.41; 95% CI, 0.36 to 0.47), while working experience was associated with reduced depression scores (β, -0.08; 95% CI, -0.16 to -0.01). Factors associated with increased stress scores included working experience (β, 0.08; 95% CI, 0.00 to 0.16), personal protective equipment interference with daily activities (β, 0.55; 95% CI, 0.07 to 1.00), depression scores (β, 0.54; 95% CI, 0.48 to 0.59), and anxiety scores (β, 0.45; 95% CI, 0.39 to 0.50), while age was associated with reduced stress scores (β, -0.12; 95% CI, -0.20 to -0.05)., Conclusions: Specific interventions are necessary to enhance and promote the mental health of HCWs so they can successfully cope with the circumstances of the pandemic.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has increased the workload of healthcare workers (HCWs), impacting their health. This study aimed to assess sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and identify factors associated with poor sleep among HCWs in Vietnam during the COVID-19 pandemic., Methods: In this cross-sectional study, 1000 frontline HCWs were recruited from various healthcare facilities in Vietnam between October 2021 and November 2021. Data were collected using a 3-part self-administered questionnaire, which covered demographics, sleep quality, and factors related to poor sleep. Poor sleep quality was defined as a total PSQI score of 5 or higher., Results: Participants' mean age was 33.20±6.81 years (range, 20.0-61.0), and 63.0% were women. The median work experience was 8.54±6.30 years. Approximately 6.3% had chronic comorbidities, such as hypertension and diabetes mellitus. About 59.5% were directly responsible for patient care and treatment, while 7.1% worked in tracing and sampling. A total of 73.8% reported poor sleep quality. Multivariate logistic regression revealed significant associations between poor sleep quality and the presence of chronic comorbidities (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.17 to 5.24), being a frontline HCW directly involved in patient care and treatment (OR, 1.59; 95% CI, 1.16 to 2.16), increased working hours (OR, 1.84; 95% CI,1.37 to 2.48), and a higher frequency of encountering critically ill and dying patients (OR, 1.42; 95% CI, 1.03 to 1.95)., Conclusions: The high prevalence of poor sleep among HCWs in Vietnam during the COVID-19 pandemic was similar to that in other countries. Working conditions should be adjusted to improve sleep quality among this population.

Animal studies support RCT findings of improved liver function and short-term benefits using repurposed Granulocyte Colonic Stimulating Factor GCSF in adults with decompensated cirrhosis. We describe the protocol for phase 2 RCT of sequential Kasai-GCSF under an FDA-approved IND to test that GCSF improves early bile flow and post-Kasai biliary atresia BA clinical outcome. Immediate post-Kasai neonates, age 15-180 days, with biopsy-confirmed type 3 BA, without access to early liver transplantation, will be randomized 1:1 to standard of care SOC + GCSF at 10 ug/kg in 3 daily doses within 4 days of Kasai vs SOC + NO-GCSF (ClinicalTrials.gov NCT0437391). They will be recruited from children's hospitals in Vietnam, Pakistan and one US center. The primary objective is to demonstrate that GCSF decreases the proportion of subjects with a 3-month post-Kasai serum Total Bilirubin ≥ 34 umol/L by 20%, (for a = 0.05, b = 0.80, i.e., calculated sample size of 218 subjects). The secondary objectives are to demonstrate that the frequency of post-Kasai cholangitis at 6-month and 24-month transplant-free survival are improved. The benefits are that GCSF is an affordable BA adjunct therapy, especially in developing countries, to improve biliary complications, enhance quality of liver and survival while diminishing costly liver transplantation.Clinical trial registration: A phase 1 for GCSF dose and safety determination under ClinicalTrials.gov identifier NCT03395028 was completed in 2019. The current Phase 2 trial was registered under NCT04373941., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Objective: To investigate the cause of a botulism outbreak in several provinces in Viet Nam in 2020., Methods: An initial investigation was conducted to confirm the outbreak and to form hypotheses about the potential causes, followed by a case-control assessment of the plausible causative food item. Collected food samples were tested to identify the pathogen, and mouse bioassays were performed. Control measures were introduced to stop the outbreak and to prevent similar events in the future., Results: Twelve people in six southern provinces of Viet Nam were identified as having symptoms of botulism, of whom 11 were in critical condition requiring breathing support. A history of foods eaten in the 4 days before illness onset indicated that all the cases had eaten a tinned vegetarian pâté, and a case-control assessment showed that this was significantly associated with the outbreak, with an odds ratio of 35.2 (95% confidence interval: 3.4-¥). Clostridium botulinum type B was detected in three of eight pâté samples collected from the houses of cases. In the mouse bioassay for the toxicity of the pâté samples, all the mice died with clinical symptoms of botulism., Discussion: A tinned vegetarian pâté was the plausible cause of a botulism outbreak in Viet Nam in 2020. Revision of food safety regulations to improve quality control of tinned foods to prevent future outbreaks is recommended., ((c) 2022 The authors; licensee World Health Organization.)

Aims: In RCT of adults with decompensated cirrhosis, GCSF mobilizes hematopoietic stem cells HSC and improves short-term outcome. An FDA-IND for sequential Kasai-GCSF treatment in biliary atresia BA was approved. This phase 1 study examines GCSF safety in Kasai subjects. Preliminary short-term outcome was evaluated., Methods: GCSF (Neupogen) at 5 or 10 μg/kg (n = 3/group) was given in 3 daily doses starting on day 3 of Kasai surgery (NCT03395028). Serum CD34+ HSC cell counts, and 1-month of GCSF-related adverse events were monitored. The 6-months Phase 1 clinical outcome was compared against 10 subsequent post Phase 1 Kasai patients who did not receive GCSF., Results: With GCSF, WBC and platelet count transiently increased, LFT and serum creatinine remained stable. Reversible splenic enlargement (by 8.5-20%) occurred in 5/6 subjects. HSC count increased 12-fold and 17.5-fold for the 5 μg/kg and10 ug/kg dose respectively; with respective median total bilirubin levels for GCSF vs no-GCSF groups of 55 vs 91 μM at 1 month, p = 0.05; 15 vs 37 μM at 3 months, p = 0.24); and the 6-months cholangitis frequency of 40% vs 90%, p = 0.077., Conclusions: GCSF safely mobilizes HSC in Kasai infants and may improve short-term biliary drainage and cholangitis. Phase 2 efficacy outcome of GCSF adjunct therapy for sequential Kasai and GCSF is pending., (Published by Elsevier Inc.)
