ROHHAD syndrome without rapid-onset obesity: A diagnosis challenge.

Background: ROHHAD syndrome (Rapid-onset Obesity with Hypothalamic dysfunction, Hypoventilation and Autonomic Dysregulation) is rare. Rapid-onset morbid obesity is usually the first recognizable sign of this syndrome, however a subset of patients develop ROHHAD syndrome without obesity. The prevalence of this entity is currently unknown. Alteration of respiratory control as well as dysautonomic disorders often have a fatal outcome, thus early recognition of this syndrome is essential. Material and methods: A retrospective, observational, multicenter study including all cases of ROHHAD without rapid-onset obesity diagnosed in France from 2000 to 2020. Results: Four patients were identified. Median age at diagnosis was 8 years 10 months. Median body mass index was 17.4 kg/m2. Signs of autonomic dysfunction presented first, followed by hypothalamic disorders. All four patients had sleep apnea syndrome. Hypoventilation led to the diagnosis. Three of the four children received ventilatory support, all four received hormone replacement therapy, and two received psychotropic treatment. One child in our cohort died at 2 years 10 months old. For the three surviving patients, median duration of follow-up was 7.4 years. Conclusion: ROHHAD syndrome without rapid-onset obesity is a particular entity, appearing later than ROHHAD with obesity. This entity should be considered in the presence of dysautonomia disorders without brain damage. Likewise, the occurrence of a hypothalamic syndrome with no identified etiology requires a sleep study to search for apnea and hypoventilation. The identification of ROHHAD syndrome without rapid-onset obesity is a clinical challenge, with major implications for patient prognosis.

The EEF1AKMT3/MAP2K7/TP53 axis suppresses tumor invasiveness and metastasis in gastric cancer.

The importance of methylation in the tumorigenic responses of nonhistone proteins, such as TP53, PTEN, RB1, AKT, and STAT3, has been emphasized in numerous studies. In parallel, the corresponding nonhistone protein methyltransferases have been acknowledged in the pathophysiology of cancer. Thus, this study aimed to explore the pathological role of a nonhistone methyltransferase in gastric cancer (GC), identify nonhistone substrate protein, and understand the underlying mechanism. Interestingly, among the 24 methyltransferases and methyltransferase family 16 (MTF16) proteins, EEF1AKMT3 (METTL21B) expression was prominently lower in GC tissues than in normal adjacent tissues and was associated with a worse prognosis. In addition, EEF1AKMT3-knockdown induced gastric tumor invasiveness and migration. Through gain and loss-of-function studies, mass spectrometry analysis, RNA-seq, and phospho-antibody array, we identified EEF1AKMT3 as a novel tumor-suppressive methyltransferase that catalyzes the monomethylation of MAP2K7 (MKK7) at K296, thereby decreasing the phosphorylation, ubiquitination, and degradation of TP53. Furthermore, EEF1AKMT3, p-MAP2K7, and TP53 protein levels were positively correlated in GC tissues. Collectively, our results delineate the tumor-suppressive function of the EEF1AKMT3/MAP2K7/TP53 signaling axis and suggest the dysregulation of the signaling axis as potential targeted therapy in GC.

Tobacco smoking and nicotine dependence among patients with respiratory diseases in Vietnam: Status and correlated factors.

INTRODUCTION: Understanding nicotine dependence can support clinicians in enhancing the effectiveness of treatments for respiratory patients. Our research aimed to assess the severity of nicotine dependence among patients with respiratory diseases in Vietnam and accordingly suggest potential interventions for tobacco cessation. METHODS: A cross-sectional study was conducted at the Respiratory center of Bach Mai Hospital, Hanoi, for two months of 2016 (October and November). A total of 508 respondents participated in the study Data on socio-economic characteristics and smoking patterns were collected. The Euroqol-5 dimensions-5 levels (EQ-5D-5L) and Fagerström test for nicotine dependence (FTND) were used to evaluate patient's quality of life and the nicotine dependence level, respectively. Kruskal-Wallis and Chi-square tests were used to assess the differences between variables. We applied the multivariate logistic regression and Tobit regression to categorize the association between nicotine dependence level and other factors. RESULTS: A total of 508 patients enrolled in our study. Former smokers and current smokers accounted for 8.1% and 38.6% of the sample, respectively. Current smokers were more likely to be male, work as free lancers, and report anxiety/depression. Higher level of nicotine dependence among current smokers was associated with the employment status of the patient. The mean number of cigarettes per day was 15.7 (SD = 11.1). The mean score of the FTND was 5.1 (SD = 2.0). Freelancers were more likely to be a current smoker (OR = 2.65, 95% CI = 2.21; 5.79). People who experienced anxiety/depression had a higher likelihood of smoking (OR = 2.21, 95% CI = 1.04; 4.72). CONCLUSIONS: Current smokers demonstrated a moderate level of nicotine dependence, which predict a difficult quitting and suggest the development of specialized programs to support smoking cessation counseling. Furthermore, the capabilities of physicians in supporting and counseling patients in quitting smoking should be strengthened.

Alkaloids from Phaeanthus vietnamensis with inhibitory effect on nitric oxide production lipopolysaccharide-stimulated in RAW264.7 macrophages.

The chemical study of the acidic extract of Phaeanthus vietnamensis leaves led to the isolation of one new alkaloid, vietnamine A (1) and eight known alkaloids (R,S)-2N-norberbamunine (2), grisabine (3), 1S,1'R,O,O'-dimethylgrisabine (4), dauricine (5), neothalibrine (6), vietnamine (7), xylopine (8), and argentinine (9) by NMR and MS and comparing with the data reported in the literature. Compounds 1-9 were evaluated for inhibitory NO production in RAW 264.7 macrophages, LPS-stimulated. Compounds 1-3 significantly inhibited on NO production with the IC50 values of 6.8 ± 0.9, 9.8 ± 1.0, and 7.1 ± 0.4 µg/ml, respectively.

Income Inequalities in Hepatitis B Vaccination and Willingness to Pay Among Women of Reproductive Age in Hanoi, Vietnam.

BACKGROUND: Hepatitis B virus (HBV) infection is endemic in Vietnam and can be transmitted from mother to child. Vaccination of women of reproductive age (WRA) can reduce this transmission. Because adult HBV vaccination in Vietnam follows a fee-for-service model, research is needed to determine the effect of household income on willingness to pay (WTP) to ensure equitable access to the vaccine. METHODS: A cross-sectional study was performed in Hanoi, Vietnam, in April 2018, among WRA. Questionnaires were administered to assess household income, HBV history, vaccination status, vaccine awareness, and WTP for the vaccine. Multivariable logistic and interval regression were performed to assess the impact of household income on WTP for HBV vaccine. RESULTS: This study found that 62.3% of all participants were willing to pay for the HBV vaccine with no differences in WTP across income quintiles. There were significant differences among household income levels in awareness of HBV vaccination and WTP amount beyond US$4.50 with the lowest awareness and WTP amount among women from the lowest income quintiles. CONCLUSIONS: Our data suggest the need to subsidize HBV vaccination for low-income women to ensure more equitable access to HBV vaccination. We propose that a sliding-scale payment method may be an effective strategy in light of limited funding to support vaccination expansion. An education campaign focusing on lower-income households should also be implemented in conjunction with this program. Further research would be required to evaluate consumer acceptance of this payment scheme and to develop an appropriate sliding scale to maximize vaccine uptake.

Impacts of COVID-19 on the Life and Work of Healthcare Workers During the Nationwide Partial Lockdown in Vietnam.

Background: Healthcare workers are frontline responders facing a disproportionate increase in occupational responsibilities during the COVID-19 pandemic. Added work-related stress among healthcare personnel may lead to personal and work-related repercussions, such as burnout or decreased quality of care for patients; however, little is known about how the COVID-19 pandemic affects the daily work and life of these workers. This study aimed to evaluate the personal and occupational impacts of the COVID-19 induced partial lockdown in Vietnam among hospital staff. Methods: A cross-sectional web-based study was carried out to collect demographic data and the personal and job impacts of respondents during the second week of national lockdown in April 2020. Snowball sampling technique was applied to recruit 742 hospital staff. The exploratory factor analysis (EFA) was used to examine the validity of the instrument. Results: Of the 742 respondents, 21.2% agreed that "working attitude well-maintained," followed by 16.1% of respondents who reported that there were "enough employees at work." Only 3.2% of respondents agreed that "their work was appreciated by society." Furthermore, healthcare workers in the central region were less likely to have experienced "Avoidance of disclosure and discrimination related to COVID-19" than other areas (Coef. = - 0.25, CI: -0.42 to -0.07). Being women also had a negative association with scores in "Avoidance of disclosure and discrimination related to COVID 19" domain (Coef. = -0.27, CI: -0.43 to -0.12) while having a positive association with "negative attitude towards working conditions" domain (Coef. = 0.19, CI: 0.09 to 0.3). In addition, working in administrative offices (Coef. = 0.20; 95% CI = 0.05 to 0.36) and infectious departments (Coef. = 0.36; 95% CI = 0.09 to 0.63) had a positive association with "Increased work pressure due to COVID 19" domain. Conclusion: These findings revealed marginal impacts of the COVID-19 pandemic on the work and life of hospital staff in Vietnam. Furthermore, this study highlighted the importance of implementing preventive strategies during the nationwide partial lockdown to manage hospital admissions and the burden on healthcare workers. Finally, this study characterizes targeted demographics that may benefit from appreciation by employers and society during a national pandemic.

Psychosocial Impacts of COVID-19 on Healthcare Workers During the Nationwide Partial Lockdown in Vietnam in April 2020.

Background: The psychosocial impact of COVID-19 is greater among healthcare workers (HCWs) than the general population. This study aims to identify psychosocial problems faced by HCWs in Vietnam during the national partial lockdown between 1 and 22 April 2020 and to identify risk factors associated with psychosocial issues among this population. Methods: A cross-sectional study was conducted in the second week of April 2020 during the national lockdown in Vietnam. Snowball sampling technique was used to recruit participants through web-based surveys. The Impact of Events Scale-Revised (IES-R) was used to assess the impact of COVID-19 on HCWs through online surveys. Results: Of the 349 HCWs, we found 22.6% reported psychosocial problems. Most of participants reported having exposure to COVID-19 daily (48.7%). The majority of them also felt that their job put them at risk of SARS-CoV-2 infections (90.3%) and expressed fear of potential infection (85.7%). Despite COVID-19 risks, 95.4% of participants, however, expressed their willingness to continue working at their current health facility. In addition, 94.8% of participants believed if they or their family members had been infected, their agency leaders would have provided them with appropriate medical care. Lastly, HCWs who worked in the internal medicine department who did not take care of COVID-19 patients or expressed fear of becoming infected were more likely to have higher total IES-R scores. Conclusion: Our findings suggest that the support of healthcare leaders and assurance of care might be helpful in mitigating the psychological effects of COVID-19 among HCWs in Vietnam. These resources should be tailored to HCWs who are working in different areas of health services, including staff who are not working directly with COVID-19 patients. In addition, psychosocial health resources should be provided for not only physicians but also nursing staff.

Assessing Knowledge and Attitudes Regarding Pain Management Among Nurses Working in a Geriatric Hospital in Vietnam.

BACKGROUND: Nurses play a pivotal role in pain management. Knowing more about nurses' knowledge and attitudes regarding pain is important as we develop multidisciplinary pain services. Therefore, this study aimed to assess knowledge and attitudes regarding pain management among nurses in a geriatric hospital and its associated factors. SUBJECTS AND METHODS: A survey was conducted of nurses worked at the National Geriatric Hospital over a 3-month period. The Knowledge and Attitudes Survey Regarding Pain (KASRP) was utilized to assess nurses' knowledge and attitudes toward pain management. Four domains were defined based on KASRP, included cancer-related pain, pain assessment, pharmacology and substance abuse and physical dependence. Knowledge and attitudes regarding pain were classified as poor, fair, or good (≤50%, 50% - 75%, or ≥75% of the KASRP score). Multivariate Tobit regression models were applied to identify factors associated with the knowledge and attitudes regarding pain management. RESULTS: Of 154 participants completed the survey, 72.2% (111 participants) had poor knowledge and attitudes regarding pain management. The participants had a correct mean score of 45.2% (SD = 2.2). Nurses' knowledge of pain assessment was poor, with the proportion of correct answers to nine questions ranging from 2.6% to 50%. 44.8% of nurses reported never or rarely using pain assessment tools. Nurses who had previous training regarding pain at medical universities had significantly higher scores of knowledge and attitudes compared to those without training. Nurses who often use pain assessment tools had a significantly higher level of knowledge and attitudes than those who never or rarely use them. CONCLUSION: This study highlights significant deficits of knowledge and negative attitudes regarding pain management among nurses. The subject of pain management should be applied and enhanced in the nursing undergraduate curriculum. Nurses' active participation in pain management should be encouraged by healthcare providers for older patients.

Anaplastic lymphoma kinase inhibitor NVP­TAE684 suppresses the proliferation of human pancreatic adenocarcinoma cells.

Anaplastic lymphoma kinase (ALK) is known to be an important therapeutic target in various types of cancer. NVP­TAE684, a well­known inhibitor of ALK, was revealed to exert antitumor effects in several different malignancies. However, the molecular mechanisms responsible for these antitumor effects in cancer cells, including pancreatic adenocarcinoma cells, remain unknown. In the present study, NVP­TAE684 was investigated for its antitumor effects towards pancreatic adenocarcinoma cells. MTT assay, western blot analysis, flow cytometry, caspase­3/7 activity assay and Trypan blue exclusion assay were used and it was revealed that NVP­TAE684 suppressed the proliferation of seven human pancreatic adenocarcinoma cell lines (AsPC­1, Panc­1, MIA PaCa­2, Capan­1, CFPAC­1, Colo­357 and BxPC­3), and significantly increased G2/M arrest and apoptotic cell death. Furthermore, NVP­TAE684 inhibited the phosphorylation of ALK at Y1604, as well as that of downstream mediators such as AKT (S473) and ERK1/2 (Y202/T204). Notably, knocking down ALK with siRNAs also decreased proliferation and promoted G2/M arrest and apoptosis. Furthermore, inhibition of ALK with NVP­TAE684 or siRNA synergistically enhanced gemcitabine­induced cell death by inducing apoptosis. In conclusion, the findings of the present study indicated that NVP­TAE684 exerted its antitumor effects by inducing G2/M arrest and apoptosis via the inhibition of the ALK signaling pathway, and suggests its potential use as an antitumor agent against pancreatic adenocarcinoma.

Gaps in awareness of climate variability and its impacts on society among health professionals and community workers in Vietnam: Implications for COVID-19 and other epidemic response systems.

The study presents a cross-sectional analysis via a web-based survey to assess the awareness and experiences of Vietnamese health professionals and community workers on climate and epidemic changes and their impacts on society. Health professionals, medical students, and community workers were included in the survey. Factor analysis was used to explore the construct validity of measures, and Multivariable Tobit regression models were used to examine associated factors with awareness about climate and epidemic changes and impacts on society. Results showed that the awareness of participants about climate and epidemic changes was moderately-low, while the awareness about the impacts on society were moderately high. Community workers show higher awareness of climate and epidemic changes compared to health professionals. People working in provincial levels had a lower score (Coef. = -0.64, 95%CI = -1.19 to -0.09) than those working in central level. Compared to Northern participants, those living in Central and Southern regions have lower awareness scores regarding "Changes in weather and epidemics" and "Changes in the environment" compared to Northern people. The higher awareness about climate and epidemic changes were found to be correlated with the higher awareness of "Impacts on health, society and economy" and "Impact on individuals and families". Community workers scored lower in "Impact on individuals and families" compared to health professionals (Coef.-0.75; 95%CI = -1.34 to -0.16). This study emphasized the vulnerabilities of Vietnamese communities to epidemics and climate change. It suggests the involvements of intersectoral taskforces in the preparedness and responses to climate change and epidemics.

Survival Outcomes of Vietnamese People with HIV after Initiating Antiretroviral Treatment: Role of Clinic-Related Factors.

Given the rapid development of HIV clinics in Vietnam, this study evaluates the infrastructure surrounding this expansion, identifying clinic-related factors that impact survival outcomes. A retrospective longitudinal study was conducted among people living with HIV (PLWH) who initiated antiretroviral therapy (ART) between 2011 and 2015 among 62 ART clinics in 15 provinces. The mortality rate during the 717674.1 person-years of observation (PYO) was 0.29/100 PYO. Location in rural areas (versus urban) and in Central Vietnam (versus Northern Vietnam) were associated with higher risk of mortality. The risk was lower among clinics that had peer-educators. As Vietnam's HIV/AIDS program continues to expand, this data supports increasing resource allocation for rural clinics, incorporation of ART with the community's existing healthcare infrastructure in its efforts to decentralize, and integration of services to reflect patients' anticipated needs.

Anxiety and Depression Among People Under the Nationwide Partial Lockdown in Vietnam.

This study aimed to evaluate the psychological effects of the partial lockdown on the people in Vietnam during the COVID-19 pandemic. An online questionnaire regarding attitudes toward COVID-19 along with psychological parameters, including the Impact of Event Scale-Revised (IES-R) Depression, Anxiety, Stress Scale-21 (DASS-21) was conducted. From a total of 1,382 questionnaires, the respondents reported low prevalence of depression (4.9%), anxiety (7.0%), and stress (3.4%). The mean DASS-21 scores recorded were also markedly lower compared to similar studies conducted in China, Italy, and Iran. Respondents who reported severe PTSD had significantly higher depression, anxiety, and stress levels. Factors that were associated with an increased level of depression, stress, and anxiety were being single, separated, or widowed, a higher education level, a larger family size, loss of jobs and being in contact with potential COVID-19 patients. Contrary to expectations, the level of depression, stress, and anxiety observed has been low. Our findings can aid in future research on the impact of a partial lockdown and guide mental health professionals in Vietnam and other countries in the preparation of better care for populations under such circumstances.

Neurocognition in Congenital Central Hypoventilation Syndrome: influence of genotype and ventilation method.

BACKGROUND: Congenital Central Hypoventilation Syndrome (CCHS) is characterized by central hypoventilation due to abnormal autonomic control of breathing and global dysautonomia. Patients harbour heterozygous PHOX-2B gene mutations which are polyalanine repeats of various lengths in most of the cases. A few previous studies have reported learning difficulties and neuropsychological disorders in patients with CCHS. The aims of the present study were (1) to explore the intellectual abilities of a group of children with CCHS followed up in the centre of reference for CCHS in France using the Wechsler batteries of tests, (2) and to assess whether there was any association between CCHS characteristics and various domains of the intellectual functioning. RESULTS: There were 34 consecutive patients (15 males, 19 females) of mean (SD) age of 7.8 (3.8) years, ranging from 4 to 16 years and 6 months. Mean score of full-scale intelligence quotient was 82 (20), being in the low average range. Indexes of working memory and processing speed were significantly lower as compared to the other Wechsler indexes. There were two important findings: (1) full-scale intelligence quotient as well as indexes of verbal comprehension and processing speed were significantly greater in patients with mask ventilation than in those with tracheostomy ventilation (p = 0.012, 0.032 and 0.042 respectively); (2) most interestingly, in the patients with polyalanine repeats mutations, all intellectual indexes negatively correlated with the number of polyalanine expansion, with statistical significance reached for indexes of fluid reasoning and working memory (R = - 0.449, p = 0.032 and R = - 0.562, p = 0.012 respectively). CONCLUSIONS: CCHS increased the risk to develop neurocognitive deficiencies, affecting particularly speed of processing and working memory. Our results suggested that both genetics and ventilation method could be also involved in the physiopathology of neurocognitive impairment. Further investigations were required to untangle the complex underlying processes. Neurocognitive assessments should be performed regularly in children with CCHS in order to plan re-education programs, adapt school integration and improve quality of life.

Evidence of COVID-19 Impacts on Occupations During the First Vietnamese National Lockdown.

Background: Although "social isolation" protects the life and health of Vietnamese citizens from the adverse effects of the COVID-19 pandemic, it also triggers massive reductions in the economic activities of the country. Objective: our study aimed to identify negative impacts of COVID-19 on occupations of Vietnamese people during the first national lockdown, including the quality and quantity of jobs as well as adverse problems at work due to COVID-19. Methods: A cross-sectional study using web-based platforms was conducted during the first time of social isolation in Vietnam at the beginning of April 2020. We utilized a respondent-driven sampling technique to select 1423 respondents from 63 cities and provinces over Vietnam. Exploratory factor analysis (EFA) was used to define sub-domains of perceived impacts of COVID-19 on occupations. Findings: Approximately two-thirds of respondents reported decreases in their income (61.6%), and 28.2% reported that their income deficit was 40% and above. The percentage of female individuals having decreased revenue due to COVID-19 was higher than that of male respondents (65.2% and 54.7%, respectively). "Worry that colleagues exposed to COVID-19 patients" and "Being alienated because employment-related to COVID-19" accounted for the highest score in each factor. Compared to healthcare workers, being self-employed/unemployed/retired were less likely to suffer from "Increased workload and conflicts due to COVID-19" and "Disclosure and discrimination related to COVID-19 work exposure." Conclusion: Our study revealed a drastic reduction in both the quality and quantity of working, as well as the increased fear and stigmatization of exposure to COVID-19 at workplaces. Health protection and economic support are immediate targets that should be focused on when implementing policies and regulations.

Guidelines for diagnosis and management of congenital central hypoventilation syndrome.

BACKGROUND: Congenital Central Hypoventilation Syndrome (CCHS) is a rare condition characterized by an alveolar hypoventilation due to a deficient autonomic central control of ventilation and a global autonomic dysfunction. Paired-like homeobox 2B (PHOX2B) mutations are found in most of the patients with CCHS. In recent years, the condition has evolved from a life-threatening neonatal onset disorder to include broader and milder clinical presentations, affecting children, adults and families. Genes other than PHOX2B have been found responsible for CCHS in rare cases and there are as yet other unknown genes that may account for the disease. At present, management relies on lifelong ventilatory support and close follow up of dysautonomic progression. BODY: This paper provides a state-of-the-art comprehensive description of CCHS and of the components of diagnostic evaluation and multi-disciplinary management, as well as considerations for future research. CONCLUSION: Awareness and knowledge of the diagnosis and management of this rare disease should be brought to a large health community including adult physicians and health carers.
