Article ; Online: Accelerating anaerobic digestion process with novel single chamber microbial electrochemical systems with baffle

Abstract	A newly designed microbial electrochemical system (MES) with the addition of a baffle between the electrodes was integrated with the anaerobic digestion (AD) process for biogas upgradation. Novel MES configuration attained an increased methane production rate of 292.6 mL/L∙d and methane yield of 0.36 ± 0.006 LCH4/gCOD, which were higher than the values (185.3 mL/L∙d and 0.33 ± 0.009 LCH4/gCOD) from the MES operation without baffle, respectively. Moreover, the MES with baffle operation resulted in increased substrate removal (88.4 ± 0.5%) and less volatile fatty acids accumulation with a high energy efficiency of 99.6 %. Microbial community analysis revealed that acids metabolizing bacteria, Firmicutes, and Methanothrix were highly enriched in the cathode biofilm of MES with baffle. This study suggests that the baffle addition into the single chamber MES is beneficial to further improve the methanogenesis process for practical applications in the scaled-up MES-AD process.

Abstract	Introduction: Thyroid nodules are common diseases of the endocrine system, with a 5% prevalence rate in the general population. This study aimed to identify prevalence, clinical, cytological and ultrasonographic features of incidental thyroid cancer and its associated factors in Vietnam. Methods: This cross-sectional descriptive study consisted of 208 patients with incidental thyroid nodules detected by ultrasound at the Endocrinology Department, Bach Mai Hospital, Hanoi, Vietnam between November 2019 and August 2020. Clinical information, sonography characteristics of thyroid nodules, results of fine-needle aspiration biopsy (FNAB), postoperative pathology and lymph node metastasis were collected. A multiple logistic regression model was used to estimate factors associated with thyroid cancer. Results: A total of 272 thyroid nodules (from 208 participants) were included in this study. The mean age was 47.2 ± 12.0 (years). The rate of incidental thyroid cancer patients detected was 17.3%. Nodules <1 cm in size were significantly more prevalent for malignant nodules. The size of more than half of thyroid cancer nodules was 0.50-0.99 cm. Postoperative pathology of all nodules with Bethesda V and VI was papillary thyroid cancer which was consistent with cytological results. 33.3% of thyroid cancer patients have lymph node metastasis. The regression model showed that thyroid cancer was more likely to occur at a younger age (≤ 45 years vs. >45 years, OR 2.8; 95% CI: 1.3-6.1), taller-than-wide nodules (OR 6.8; 95% CI: 2.3-20.2) and hypo-echoic nodules (OR 5.2; 95% CI: 1.7-15.9). Conclusion: The study showed that the prevalence of incidental thyroid cancers was 17.3%, of which 100% was papillary carcinoma. People under the age of 45 and the presence of ultrasound characteristics, such as taller-than-wide and hypoechoic nodules increased risk for malignancy.

Abstract	Better understanding of the quality of life among nursing home residents with dementia is important for developing interventions. The objectives of this cross-sectional study were to examine factors associated with poor health-related quality of life in older people with dementia living in nursing homes in Hanoi, Vietnam. In-person interviews were conducted with 140 adults who were 60 years and older with dementia, and information about their quality of life was obtained using the Quality of Life in Alzheimer's Disease (QOL-AD) scale. The sociodemographic and clinical factors associated with poor health-related quality of life (lowest quartile) were assessed through the results of physical tests, interviews with nursing home staff, and review of medical records. The average age of the study sample was 78.3 years, 65% were women, and their average QOL-AD total score was 27.3 (SD = 4.4). Malnutrition, total dependence in activities of daily living, and urinary incontinence were associated with poor quality of life after controlling for multiple potentially confounding factors. Our findings show that Vietnamese nursing home residents with dementia have a moderate total quality of life score, and interventions based on comprehensive geriatric assessment remain needed to modify risk factors related to poor health-related quality of life.

Abstract	Background: A high prevalence of venom-induced consumption coagulopathy has been reported in individuals with viper snakebites. Rotational thromboelastometry (ROTEM) is a rapid technique that could be advantageous in assessing and monitoring coagulation disorders. Purpose: To explore correlations between ROTEM and standard coagulation tests. Patients and methods: This prospective observational study was performed among 41 patients with viper envenomation admitted to the Vietnam Poison Control Center from April 2016 to October 2017. Standard coagulation measurements [platelet count, prothrombin time (PT), activated partial thromboplastin time (aPTT), and fibrinogen level] and ROTEM indicators [clotting time (CT), amplitude (at set time: 5 and 10 minutes), clot information time (CFT) and maximum clot firmness (MCF) for extrinsic (EXTEM), intrinsic (INTEM), and fibrin based (FIBTEM) ROTEM] were obtained. Results: For INTEM, EXTEM, the FIBTEM, proportions of patients with prolonged CT were 34.1%, 63.4%, and 61.0% respectively and the proportions of patients with decreased MCF were 62.2%, 62.2%, and 35.5%, respectively. Moderate correlations were observed between PT and EXTEM CT (r = 0.627), aPTT and INTEM CT (r = 0.626), fibrinogen and FIBTEM MCF (r = 0.723), and platelet count and EXTEM MCF (0.60). Conclusion: ROTEM indicated a hypocoagulation state in patients with viper snakebite and was moderately correlated with standard coagulation parameters.

Abstract	In total, 130 tissue-pooled samples collected from ducks in some provinces/cities in north Vietnam were examined for waterfowl parvovirus genome identification. Twenty-six (20%) samples were positive for the parvovirus infection, based on polymerase chain reaction analysis. Of the 38 farms tested, 14 (36.84%) were positive for the waterfowl parvovirus genome. The rate of the parvovirus genome detection in ducks aged 2−4 weeks (37.04%) was significantly (p < 0.05) higher than that at ages <2 weeks (9.09%) and >4 weeks (16.30%). The positive rate on medium-scale farms (9.36%) was significantly (p < 0.05) lower than for small-scale (31.03%) and large-scale (29.73%) farms. The lengths of the four Vietnamese waterfowl parvovirus genomes identified were 4750 nucleotides. Among the four Vietnamese parvovirus genomes, nucleotide identities were from 99.29% to 99.87%. Phylogenetic analysis of the near-complete genomes indicated that the waterfowl circulating in northern Vietnam belonged to the novel goose parvovirus (NGPV) group. The Vietnamese NGPV group was closely related to the Chinese group. Recombination analysis suggested that the Vietnam/VNUA-26/2021 strain was generated by a recombination event. One positive selection site of the capsid protein was detected.

Abstract	Purpose: The aim of this study was to explore the impact of frailty on in-hospital adverse outcomes and net adverse clinical events (NACE) in older patients with acute coronary syndrome. Patients and methods: This observational study included elderly patients (≥60 years old), diagnosed with acute coronary syndrome (ACS) at admission from February 2021 to August 2021. The primary outcome was net adverse clinical events (NACE) defined as a composite of all-cause mortality, stroke, and major bleeding. Secondary outcome was in-hospital adverse outcomes including arrhythmia, acquired pneumonia, stroke, major bleeding, and all-cause mortality. Frailty was assessed using the Frail scale (FS). Data about socio-demographics, comorbidities, body mass index, ACS type, coronary angiography, left ventricular ejection fraction, and length of hospital stay were also collected. Univariate and multivariate logistic regressions were employed to identify the potential association between frailty and outcomes. Results: Of the 116 ACS patients, 38 patients were frail (32.76%). Frail subjects were more often female (50%) and older (p < 0.01) and had higher rates of in-hospital adverse outcomes (OR = 2.37, p = 0.05) and NACE (OR = 7.12; p < 0.01). In univariate analysis, the increased frail score was significantly associated with increased odds of NACE (unadjusted OR = 1.98, 95% CI 1.17-3.35 for each score increase in Frail Score). In multivariable logistic regression, models controlling for age, gender, PCI, LVEF, and coronary angiography (adjusted OR 2.19, 95% CI 1.12-4.29 for each score increase in Frail Score). Conclusion: This study revealed the reference data of frailty assessment in older patients with ACS in Vietnam. Our result indicated that over 30% of ACS older patients presented with frailty which was associated with an increased risk of in-hospital adverse outcomes and NACE. This study also provided promising information about the simple FRAIL scale's potential role in the risk stratification of older patients with ACS.

Abstract	Objectives: This study aimed to investigate the relationship between sarcopenia and frailty and examine factors associated with frailty among older patients with and without sarcopenia. Methods: This cross-sectional study was conducted on older inpatients and outpatients in Vietnam. Participants aged 60 years or older were consecutively enrolled in the study. Sarcopenia was defined using the Asian Working Group for Sarcopenia (AWGS) 2019 criteria. Fried's frailty phenotype was applied to define frailty. Logistic regression models with frailty as the dependent variable were applied. Results: A total of 835 patients (mean age: 71.3 years, SD 8.4) were recruited. The overall prevalence of frailty was 17%. Among participants with and without frailty, 92% and 47% had sarcopenia, respectively. In unadjusted analysis, sarcopenia was significantly associated with increased frailty (OR 12.3, 95% CI 6.7-22.6) and remained significant after adjustment for sociodemographic factors (OR 6.3, 95% CI: 3.0-12.6) and for both sociodemographic and clinical factors (OR 5.4, 95% CI: 2.4-12.2). Among participants with sarcopenia, older age, inpatient status, having a high risk for falls, malnutrition and a history of hospitalisation in the last year were significantly associated with frailty. Among participants without sarcopenia, the factors associated with frailty were older age, inpatient status, low educational level, high risk of falls and malnutrition. Conclusions: Our study results highlighted that sarcopenia and frailty are two related but distinct geriatric syndromes.

Abstract	Background: Methadone Maintenance Treatment (MMT) program's success depends on the likelihood of reducing drop-out rate and keeping patients remaining in the program. There have been neither comprehensive studies about variation among patients who have been experiencing MMT for long period nor prediction of MMT period in which the risk of drop-out would be the highest in Thai Nguyen, a northern mountainous province where the MMT was established in 2011. Objectives: To analyze variation of the MMT population through indicators of drop-out and death, re-enrolment, and retention rate in the six Thai Nguyen MMT clinics. Methods: A retrospective study by reviewing daily treatment notebooks of the six MMT clinics in Thai Nguyen to identify events of drop-out, death, reenrolment among 2,567 patients registered from 12 May 2011 to 6 September 2015. Results: Cumulative hazard of drop-out over period from the first to the fourth year of MMT treatment has an increasing trend at 0.15; 0.31; 0.46; and 0.61, respectively. The cumulative probability of re-enrolment among 740 patients who have already quit the MMT program and then returned slightly increased from 0.07 to 0.16 between the first years and the fourth year in which the highest returning rate occurred within the first 2 years after drop-out. The cumulative retention rate decreased annually and stayed at 71.7% after 4 years of running the MMT. Conclusions: MMT patients and their families should be informed and consulted about the highest risk period of drop-out and also about period when drop-out patients are most likely to reenter the MMT. Counseling adherence for patients should be conducted not only at the beginning but also during the ongoing MMT and play an extremely important role in reducing drop-out of the program while special counseling should also be reenforced for the re-enrolment patients of MMT.
