Abstract
OBJECTIVES This study aimed to determine (1) the needsof Vietnamese people with epilepsy (PWE) and their caregivers for self-management mobile health applications and (2) the self-management features expected to be included in an application. METHODS The survey consisted of an anonymous self-administered questionnaire that was distributed to PWE and caregivers from the age of 18 in Vietnam through online platforms and onsite at Nguyen Tri Phuong Hospital and University Medical Center, Ho Chi Minh City, from February 2022 to May 2022. The questionnaire assessed the participants' attitudes toward epilepsy self-management mobile applications, their willingness to use applications, and their expectations of the contents of an application. RESULTS Responses from 103 participants were submitted. Eighty-one participants (78.6%) reported using a smartphone, but only 50.6% of those claimed to know about self-management applications. Most respondents (70.9%) thought the applications would be useful for disease self-management, and 68.9% were willing to use epilepsy self-management applications. In addition, the most expected features to be included in self-management applications were epilepsy information, seizure first aid, connecting with medical professionals, and a seizure diary. CONCLUSION Most Vietnamese PWE and caregivers had a willingness to use epilepsy self-management applications.The expected features are related to all aspects of self-management, including information, seizure, medication, and safety management.

Abstract
Introduction Circulating cell-free RNA (cfRNA) is a potential hallmark for early diagnosis of Alzheimer's Disease (AD) as it construes the genetic expression level, giving insights into the pathological progress from the outset. Profiles of cfRNA in Caucasian AD patients have been investigated thoroughly, yet there was no report exploring cfRNAs in the ASEAN groups. This study examined the gap, expecting to support the development of point-of-care AD diagnosis. Methods cfRNA profiles were characterized from 20 Vietnamese plasma samples (10 probable AD and 10 age-matched controls). RNA reads were subjected to differential expression (DE) analysis. Weighted gene correlation network analysis (WGCNA) was performed to identify gene modules that were significantly co-expressed. These modules' expression profiles were then correlated with AD status to identify relevant modules. Genes with the highest intramodular connectivity (module membership) were selected as hub genes. Transcript counts of differentially expressed genes were correlated with key AD measures-MMSE and MTA scores-to identify potential biomarkers. Results 136 genes were identified as significant AD hallmarks (p < 0.05), with 52 downregulated and 84 upregulated in the AD cohort. 45.6% of these genes are highly expressed in the hippocampus, cerebellum, and cerebral cortex. Notably, all markers related to chronic inflammation were upregulated, and there was a significant shift in all apoptotic markers. Three co-expressed modules were found to be significantly correlated with Alzheimer's status (p < 0.05; R2> 0.5). Functional enrichment analysis on these modules reveals an association with focal adhesion, nucleocytoplasmic transport, and metal ion response leading to apoptosis, suggesting the potential participation of these pathways in AD pathology. 47 significant hub genes were found to be differentially expressed genes with the highest connectivity. Six significant hub genes (CREB1, YTHDC1, IL1RL1, PHACTR2, ANKRD36B, RNF213) were found to be significantly correlated with MTA and MMSE scores. Other significant transcripts (XRN1, UBB, CHP1, THBS1, S100A9) were found to be involved in inflammation and neuronal death. Overall, we have identified candidate transcripts in plasma cf-RNA that are differentially expressed and are implicated in inflammation and apoptosis, which can jumpstart further investigations into applying cf-RNA as an AD biomarker in Vietnam and ASEAN countries.

Abstract
Production of affordable coronavirus disease 2019 (COVID-19) vaccines in low- and middle-income countries is needed. NDV-HXP-S is an inactivated egg-based Newcastle disease virus (NDV) vaccine expressing the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Wuhan-Hu-1. The spike protein was stabilized and incorporated into NDV virions by removing the polybasic furin cleavage site, introducing the transmembrane domain and cytoplasmic tail of the fusion protein of NDV, and introducing six prolines for stabilization in the prefusion state. Vaccine production and clinical development was initiated in Vietnam, Thailand, and Brazil. Here the interim results from the first stage of the randomized, dose-escalation, observer-blind, placebo-controlled, phase 1/2 trial conducted at the Hanoi Medical University (Vietnam) are presented. Healthy adults aged 18-59 years, non-pregnant, and with self-reported negative history for SARS-CoV-2 infection were eligible. Participants were randomized to receive one of five treatments by intramuscular injection twice, 28 days apart: 1 μg +/- CpG1018 (a toll-like receptor 9 agonist), 3 μg alone, 10 μg alone, or placebo. Participants and personnel assessing outcomes were masked to treatment. The primary outcomes were solicited adverse events (AEs) during 7 days and subject-reported AEs during 28 days after each vaccination. Investigators further reviewed subject-reported AEs. Secondary outcomes were immunogenicity measures (anti-spike immunoglobulin G [IgG] and pseudotyped virus neutralization). This interim analysis assessed safety 56 days after first vaccination (day 57) in treatment-exposed individuals and immunogenicity through 14 days after second vaccination (day 43) per protocol. Between March 15 and April 23, 2021, 224 individuals were screened and 120 were enrolled (25 per group for active vaccination and 20 for placebo). All subjects received two doses. The most common solicited AEs among those receiving active vaccine or placebo were all predominantly mild and included injection site pain or tenderness (<58%), fatigue or malaise (<22%), headache (<21%), and myalgia (<14%). No higher proportion of the solicited AEs were observed for any group of active vaccine. The proportion reporting vaccine-related AEs during the 28 days after either vaccination ranged from 4% to 8% among vaccine groups and was 5% in controls. No vaccine-related serious adverse event occurred. The immune response in the 10 μg formulation group was highest, followed by 1 μg + CpG1018, 3 μg, and 1 μg formulations. Fourteen days after the second vaccination, the geometric mean concentrations (GMC) of 50% neutralizing antibody against the homologous Wuhan-Hu-1 pseudovirus ranged from 56.07 IU/mL (1 μg, 95% CI 37.01, 84.94) to 246.19 IU/mL (10 μg, 95% CI 151.97, 398.82), with 84% to 96% of vaccine groups attaining a ≥ 4-fold increase over baseline. This was compared to a panel of human convalescent sera (N = 29, 72.93 95% CI 33.00-161.14). Live virus neutralization to the B.1.617.2 (Delta) variant of concern was reduced but in line with observations for vaccines currently in use. Since the adjuvant has shown modest benefit, GMC ratio of 2.56 (95% CI, 1.4-4.6) for 1 μg +/- CpG1018, a decision was made not to continue studying it with this vaccine. NDV-HXP-S had an acceptable safety profile and potent immunogenicity. The 3 μg dose was advanced to phase 2 along with a 6 μg dose. The 10 μg dose was not selected for evaluation in phase 2 due to potential impact on manufacturing capacity. ClinicalTrials.gov NCT04830800.

Abstract
INTRODUCTION In Vietnam, Alzheimer's disease (AD) and other dementias have become an increasingly important public health problem among the elderly. Achieving a diagnosis tool with high reliability and validity is essential. The Clinical Dementia Rating (CDR) is a global clinical scale with established diagnostic and severity-ranking utility that has been widely employed in epidemiological studies in an international context. OBJECTIVE The aims of this study were to establish the Vietnamese version of the CDR (V-CDR) and evaluate the feasibility, reliability, and validity of this version for diagnosing and classifying cognitive functions in the elderly. METHOD One hundred and fifty-three elderly outpatients at a clinic of Cho Ray Hospital, Vietnam, were screened with the Mini Mental State Examination (MMSE) for potential cognitive impairment. All those who scored ≤26 points were included in the study and were subsequently remitted to the V-CDR and clinical assessment for diagnosis. Reliability was assessed through internal consistency (Cronbach α), intra- and interrater reliability (weighted κ). Concurrent and discriminative validity of the V-CDR were assessed. RESULTS The V-CDR had an excellent internal consistency for each of the 2 raters (Cronbach α 0.90 and 0.96) and excellent agreement in both intra- and interrater reliability (weighted κ 0.84 [95% CI 0.74-0.94] and 0.82 [95% CI 0.72-0.93], respectively). The sensitivity and specificity for detecting dementia were 93.6 and 100%, respectively. The positive and negative predictive value were 100 and 96.4%, respectively. The agreement of V-CDR and clinical assessment was excellent (weighted κ 0.94 [95% CI 0.88-0.99]). V-CDR was substantially better than MMSE at distinguishing between mild cognitive impairment and normal cognitive function (AUC = 0.957, 95% CI 0.893-1.000 vs. AUC 0.594, 95% CI 0.441-0.746). CONCLUSIONS The V-CDR is a feasible, reliable, and valid instrument which should be used in clinical practice for diagnosing and classifying the different dementia stages in the elderly.

Abstract
Background In Vietnam, there has been, currently, no standardized tool for depression assessment for people with dementia (PWD). Cornell Scale for Depression in Dementia (CSDD) is a widely studied and used scale for PWD worldwide. Objectives The aim of this study was to standardize the Vietnamese version of the CSDD (V-CSDD) in depression assessment in PWD through reliability and validity examination. Methods V-CSDD was rated in terms of reliability and validity with gold standard regarding “major depressive episode” and “major depressive-like episode” of DSM-5. Cronbach's α, ICC, exploratory factor analysis (EFA), and receiver operating characteristic analysis were performed. Results V-CSDD was found to have a high internal consistency reliability (Cronbach's α = 0.80), inter-rater reliability at sound ranking (ICC = 0.89; 95% CI = 0.81–0.94), maximum cut-off mark of 13 (sensitivity = 70%, specificity = 92%), and EFA, which suggested that V-CSDD may comprise 5 factors. Conclusions Results indicate the V-CSDD to be a reliable and valid assessment and to be beneficial in classifying and diagnosing depression in dementia outpatients in clinical contexts.

Abstract
Purpose of the study: Alzheimer's disease (AD) is the most common type of dementia and its prevalence is rapidly increasing worldwide. Early-onset Alzheimer's disease (EOAD) constitutes of patients with age of onset earlier than 65 year-old and is known to be associated with genetic mutations. In this study, we reported the first genetic analysis of Vietnamese patients with EOAD.Materials and methods: We analyzed targeted sequencing data obtained from a cohort of 51 Vietnamese EOAD patients to identify pathogenic variants in twenty nine well-characterized neurodengerative genes.Results: We identified four missense mutations in APP/PSEN1 genes from six individuals, which accounts for 11.8% of all tested cases. Three of these mutations were previously reported as pathogenic and one mutation in the APP gene was newly identified and might be specific for Vietnamese patients. Our study also found eight individuals carrying homozygous APOE ε4 allele, the main risk factor gene for late-onset AD.Conclusions: Our findings showed that mutation rate in APP/PSEN genes in Vietnamese EOAD patients is consistent with that in other ethnic groups. Although further functional studies are required to validate the pathogenesis of the new mutations, our study demonstrated the necessity of genetic screening for EOAD patients as well as additional genetic data collection in Vietnamese population.

Abstract
Persistent trigeminal artery (PTA) originates from the posterior bend or lateral wall of the intra-cavernous carotid artery and is the most common occurring type of remnant primitive fetal arteries. In literature, there is limited number of reports on migraine-cephalgia (MC) associated with coexisting PTA. The primitive anastomose arteries that fully belong to the intracranial arterial vascular system are not supposed to perform any supportive functional activity; usually they are subjected to normal biological decay caused by the aging process and metabolic dysfunctions. The hypothesis suggests that these primitive fetal arteries such as PTA may not undergo a fast and structural deterioration but they might be active contributors to a series of mechanisms that can cause a variety of idiopathic complaints. Consequently this would bring a different therapeutic approach other than their surgical removal, which is the accepted option today as a solution for these problems. In this case report, a chronic unilateral MC due to coexisting PTA adjacent to trigeminal nerve is presented. The caliber and location of the PTA was confirmed by a CT-Angiography. The MC treatment was achieved by administration of bio-identical testosterone, human placenta extract (HPE), b-nicotinamide adenine dinucleotide (NADH) and low dose amlopidine.

Abstract
The rarely diagnosed persistent trigeminal artery (PTA) originates from the posterior bend or lateral wall of the intracavernous carotid artery and is the most common occurring type of remnant primitive fetal arteries. Even if PTA is uncommon, information and awareness about it could be of great help for clinicians dealing with cranial vascular imaging and operating this region. In addition, it could give a supporting response to the presence of a wide range of idiopathic and unresponsive disturbs that sometimes are erroneously interpreted and treated. There are very few published scientific reports of coexisting PTA and unilateral trigeminal neuralgia and migraine-cephalgia (MC). In this review we describe few reported and unreported cases regarding the manifestation of unresponsive trigeminal neuralgia and migraine due to the presence of PTA. Patients usually present with a clinical symptomatology with unstable blood hypertension, pain of typical trigeminal neuralgia and MC that cover unilaterally the occipital area over the second and third divisions of the nerve. The outbreaks may often become more severe during physical exertion, stress and hypertension. Angio-MRI may reveal the PTA with an occasional occurrence of parietal cavernoma. We also describe a case of chronic left MC case associated with an adjacent PTA close to the trigeminal nerve position. The size and location of the PTA was confirmed by a CT-Angiography. The MC was safely treated by bio-identical testosterone, human placenta extract (HPE), b-nicotinamide adenine dinucleotide (NADH) and low dose amlopidine. It is hypothesized that these types of primitive anastomose arteries that fully belong to the intracranial arterial vascular system do not perform any supportive functional activity. Nevertheless, they undergo the normal biological decay caused by the aging process and metabolic dysfunctions. Therefore, such primitive fetal arteries as PTA might be subjected not only to a faster structural deterioration but they would actively contribute to a series of mechanisms causing a variety of idiopathic intracranial vascular and structural symptoms. Consequently, this would change the primary therapeutic approach to solve this problem, today represented by surgical removal. Anatomic implications related to treatment procedure are also discussed.

Abstract
Osseo-degeneration is a disorder related to several factors, that may lead to the disruption of several skeletal regions providing support, such as the femur head, the vertebrae and the alveolar bone. The functional condition can be restored by means of grafting procedures, using different materials: calcium powder, xenografts, ceramics and metals. Such procedures aim at reforming an adequate bone volume and strength, that is necessary to support loading forces. Bone regeneration requires that the basic biological principles of osteogenesis, osteoinduction, osteoconduction and biocompatibility are followed. The success of regenerative procedures may depend on the inner structural, mechanical and metabolic condition of the host's bone on which implants should be inserted, on the surgical technique, and on the biomaterial used. Among these, the aging process of the patient appears to be relevant. It can be associated with metabolic disease leading to systemic functional decay, which involves a gradual steady decline of hormonal, immune function and osteo-metabolic activity. The latter can affect the positive outcomes of bone reconstruction and implant therapy. This review will analyze the biological and physiological factors involved in the bone tissue break-down, such as the influences from gut microbiome unbalance and the consequent metabolic, endocrine, immune dysfunctions, the surgery procedures and the quality of the grafting material used. The decline of bone architecture and strength should be corrected by using an appropriate clinical regenerative approach, based on a bio-endocrine, metabolic and immunologic know-how. The final characteristics of the regenerated bone must be able to support the loading forces transmitted by the implants, independent of the body location, and should be individualized according to the different condition of each patient.

Abstract
BACKGROUND Active surveillance (AS) is an appropriate management strategy for men with low-risk prostate cancer. Most protocols recommend repeated prostate biopsy every 12-24 months. The purpose of this paper is to describe histological inflammation patterns in men on AS who underwent serial prostate biopsy for disease monitoring. METHODS We reviewed records of men on AS from January 1999 through February 2011 who had a diagnostic plus ≥1 repeat transrectal ultrasound-guided biopsies performed at our institution. The type and degree of inflammatory infiltrate were grossly reviewed and scored for each patient's biopsy by a single pathologist. Relationship of inflammation severity and number of serial biopsies was assessed using a repeated measures mixed model. Unpaired t-test and χ(2)-square analysis assessed variance in degree of inflammation and location of inflammation relative to cancer grade progression defined as Gleason sum increase. RESULTS Fifty-six men met study inclusion criteria. Mean age was 62.1 (6.5) years, 71% were stage cT1c, 79% had a PSA level <10 ng ml(-1), and 98% had diagnostic Gleason sum ≤6. A small, statistically significant increase in maximum chronic inflammation (CI) scores with greater number of repeat biopsies was observed. CI scores were not associated with number of biopsies based on upgrade status. The main limitation to our study is our small sample size. Potential unmeasured confounders, such as unreported antibiotic use or symptomatic prostatitis, may have also affected our findings. CONCLUSIONS In this pilot study of 56 men on AS for localized prostate cancer, degree of chronic histological inflammation increased with greater number of prostate biopsies, but was not associated with subsequent risk of grade progression.

Abstract
BACKGROUND General surgeons commonly perform upper gastrointestinal endoscopy in practice, but few perform endoscopic retrograde cholangiopancreatography (ERCP), partly because of limited training opportunities. This report focuses on the value of an ERCP fellowship training program to a broad-based, mature residency in surgery and our observations on the experience required for surgeons to be trained in advanced interventional ERCP. METHODS Since the program was initiated in 1992, 13 ERCP fellows have been trained for individual periods of 6 to 14 months. This study investigated all procedures with fellow involvement (2,008 cases) from among a total experience of 3,641 ERCPs. Data collected included type of ERCP (diagnostic/therapeutic), fellow success in cannulating the duct of interest, and faculty success in cases of fellows who failed. Of the 13 fellows, 9 had previous endoscopy experience, but none had training in ERCP. RESULTS An 85% cannulation rate was accepted as successful, and cannulation rates for each fellow were calculated for each 3-month period. The 85% mark was reached by 4 (31%) of 13 fellows in the first period, 2 of 13 fellows (15%) in the second period, 5 of 11 fellows (45%) in the third period, 7 of 10 fellows (70%) in the fourth period, and 1 of 1 fellow (100%) in the fifth period of training. On the average, it took 7.1 months and 102 ERCPs for trainees to reach desired success levels. Success came more promptly with prior exposure to endoscopy. Fellows without prior endoscopic experience required 148 cases to reach 85% success. Resident surgical experience with major pancreatic resections increased threefold after establishment of the fellowship. CONCLUSIONS Training in ERCP is possible within the scope of a surgical fellowship in a reasonable length of time and experience. Complication rates remain low even with fellow involvement. Establishment of an ERCP program increases the focus and experience of pancreas surgery in a surgical residency for chief residents.

Abstract
We have been interested in the clinical use of capillary electrophoresis (CE) to monitor low-molecular-mass uremic toxins in body fluids. Creatinine, an important clinical marker for renal failure, is zwitterionic over a fairly wide pH range (pH 5-9) and can not be resolved from neutral components using free solution CE under these conditions. We report here a micellar electrokinetic capillary chromatography method using an sodium dodecyl sulfate-borate buffer system at pH 9.0 to determine creatinine levels in human serum. This method, performed on deproteinized sera, is also suitable for determining multiple ionic components. Moreover, this method compares favorably with an enzymatic method for creatinine performed in a clinical laboratory and thus appears to be a promising method in terms of potential clinical use.
