Coronary pulmonary artery fistula (CPAF) is a rare entity in the population. It may present with multiple clinical settings and in various age ranges. Invasive coronary angiography (ICA), coronary ...computed tomography angiography (CCTA), and transthoracic echocardiography (TTE) have been reported as diagnostic tools for CPAF. Among them, TTE is rarely capable of identifying CPAF. There is no current treatment guideline as some of the interventional therapies are effective yet controversial. The therapy therefore should be individualized. We report a case of CPAF accidentally detected by TTE in a 93-year-old female who presented with acute respiratory distress on the setting of community-acquired pneumonia, diastolic heart failure, ischemic heart disease, pulmonary hypertension, chronic kidney disease, and hypertension. The patient presented with orthopnea, fever, bilateral pleuritic chest pain, and productive cough with yellowish sputum for 7 days. She had no previous chest trauma or surgical intervention. TTE demonstrated the tortuous enlargement of left coronary artery which drains into the pulmonary arterial trunk right above the pulmonary valve. As the patient was in advanced age with multiple comorbidities; we offered a conservative management including diuretic, oxygen therapy, antibiotic, antiplatelet, and statin. She recovered following a 13-day hospitalization. To our knowledge, this is the oldest case report of suspected congenital CPAF which is particularly detected by TTE.
Health-related quality of life (HRQoL) is an important construct in clinical settings, and it is crucial that it should be properly measured. As the EuroQol-5-dimensions-5 levels (EQ-5D-5L) is more ...effective for such measurement than the 3-level model, data on economic models, clinical studies, and public health evaluations previously collected through the EQ-5D-3L need to be revaluated using the EQ-5D-5L. This study evaluated colorectal cancer (CRC) patients' HRQoL scores using the Vietnamese EQ-5D-5L value set.
The cross-sectional study included CRC patients treated at a tertiary public hospital. HRQoL was assessed using the EQ-5D-5L, and HRQoL utility scores were calculated using the Vietnamese value set. Tobit regression examined factors associated with HRQoL.
The analysis included 197 CRC patients. Ages ranged from 20 to 87 years (M = 57.64, SD = 13.5); 42.2% and 57.8% were diagnosed with cancer of the colon or rectum/anus, respectively. Mean EQ-5D-5L was 0.561 (range, -0.5115 to 1). Most participants experienced anxiety/depression (88%), followed by pain/discomfort (87%), mobility (71%), usual activity (69%), and self-care (67%). Advanced CRC stage (stage II: β -0.303, se 0.08; stage III: β -0.305, se 0.07; stage IV: β -0.456, se 0.07) and surgery (β -0.113, se 0.05) were negatively associated with EQ-5D-5L scores. Advanced education (high school: β 0.273, se 0.07); college/vocational: β 0.134se 0.05; university/higher: Coef 0.213, se 0.08;) and older age (age group 35-44: β 0.253, se 0.10; 45-54: β 0.327, se 0.09; 55-64: β 0.355 se 0.09; 65+ β 0.204, se 0.09) were positively associated with EQ-5D-5L scores.
Patients in advanced CRC stages or undergoing surgery experienced lower HRQoL and higher prevalence of anxiety/depression and pain/discomfort. Older age and high educational attainment predicted high HRQoL. This study provides information on CRC patients' health utility based on various patient characteristics, which can be used in future economic evaluations.
It is difficult to track the philosophy foundation and epistemology of systemic functional grammar (SFG) formulated by Halliday in the 1980s as this kind of grammar views language as a systemic ...resource for meaning. Besides, it has had global impacts on linguistics and flourished in contemporary linguistic theory. Anyone who is familiar with Halliday’s work realizes that his SFG is an approach designed to analyze English texts. Halliday (1994: xv) explicitly states that “to construct a grammar for purposes of text analysis: one that would make it possible to say sensible and useful things about any text, spoken or written, in modern English.” The aim of this study is not about the applicability of SFG to text analysis as many researchers and scholars do. Our efforts are made to clarify the philosophical foundation of Halliday’s SFG. The paper presents on triangle: (i) language, mind and world; (ii) and empiricism in Halliday’s SFG.
(
) remains a major cause of gastroduodenal diseases. We aimed to evaluate the burden of this infection, particularly peptic ulcer disease in Vietnamese children.
We enrolled consecutive children ...referred for esophagogastroduodenoscopy at two tertiary children's hospitals in Ho Chi Minh City, from October 2019 to May 2021. Children treated with proton pump inhibitors during the last two weeks or antibiotics for four weeks, and those having a previous or interventional endoscopy were excluded.
infection was diagnosed with either a positive culture or positive histopathology combined with a rapid urease test, or with a polymerase chain reaction of the urease gene. The study was approved by the Ethics Committee and written informed consent/assent was obtained.
Among 336 enrolled children aged 4-16 (mean: 9.1 ± 2.4 years; 55.4% girls),
infection was positive in 80%. Peptic ulcers were detected in 65 (19%), increasing with age, and 25% with anemia.
strains were detected at a higher rate in children with ulcers.
Prevalence of
and peptic ulcers is high among symptomatic Vietnamese children. It is crucial to have a program for early detection of
to reduce ulcer risk and gastric cancer later.
A series of 4-anilinoquinazoline–triazole–AZT hybrids were designed and synthesized as anticancer agents. Their cytotoxic potential has been evaluated by means of a micro-dilution assay against three ...human cancer cell lines (KB, epidermoid carcinoma; HepG2, hepatoma carcinoma; SK-Lu-1, non-small lung cancer). The biological results revealed that compounds 4b and 6d showed good anticancer activities against KB, HepG2, and Lu cell lines (IC50 values ranging from 9 μM to 100 μM). Especially, compounds 4b and 6d exhibited up to 3-fold more potent than reference drugs erlotinib hydrochloride and AZT in term of anti-lung cancer activity.
Organo-lead mixed halide perovskites have been showing remarkable performance for applications in solar cells and are very promising for numerous applications in optoelectronics and nonlinear optics. ...In this study, we report a room-temperature photoluminescence study of this material by using pulsed excitation laser sources at 1064 nm wavelength. Under our experimental conditions, strong photoluminescence was observed only for bromine-containing perovskites, CH

This direct observation of three-photon absorption-induced photoluminescence of organo-lead mixed halide perovskite materials thus opens up interesting applications in the field of optoelectronics and nonlinear optics.
Hemiasterlin is a potent antimitotic agent acting through inhibition of microtubule depolymerization. For this reason, the synthesis of new hemiasterlin derivatives has attracted a lot of interest in ...the organic chemistry community recently. In this paper, the synthesis and evaluation of the cytotoxicity of new simplified and racemic hemiasterlin derivatives were reported. All of the synthesized analogues were evaluated in vitro for cytotoxic activity against four human cell lines (KB, Hep-G2, LU and MCF7). Most of these analogues possess a strong cytotoxic activity on two human cancer cell lines (KB and Hep-G2) and very weak activity on LU and MCF7 cell lines.
The aim of this paper was to develop a leadership and managerial competency framework for public hospital managers in Vietnam.
This mixed-method study used a four-step approach. The first step was a ...position description content analysis to identify the tasks hospital managers are required to carry out. The resulting data were used to identify the leadership and managerial competency factors and items in the second step. In the third step, a workshop was organized to reach consensus about the validity of these competency factors and items. Finally, a quantitative survey was conducted across a sample of 891 hospital managers who are working in the selected hospitals in seven geographical regions in Vietnam to validate the competency scales using exploratory factor analysis (EFA) and Cronbach's alpha.
The study identified a number of tasks required for public hospital managers and confirmed the competencies for implementing these tasks effectively. Four dimensions with 14 components and 81 items of leadership and managerial competencies were identified. These components exhibited 83.8% of variance and Cronbach's alpha were at good level of 0.9.
These competencies are required for public hospital managers which provide guidance to the further development of the competency-based training for the current management taskforce and preparing future hospital managers.
There are a host of emergent technologies with the potential to improve hospital care in low- and middle-income countries such as Vietnam. Wearable monitors and artificial intelligence-based decision ...support systems could be integrated with hospital-based digital health systems such as electronic health records (EHRs) to provide higher level care at a relatively low cost. However, the appropriate and sustainable application of these innovations in low- and middle-income countries requires an understanding of the local government's requirements and regulations such as technology specifications, cybersecurity, data-sharing protocols, and interoperability.
This scoping review aims to explore the current state of digital health research and the policies that govern the adoption of digital health systems in Vietnamese hospitals.
We conducted a scoping review using a modification of the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines. PubMed and Web of Science were searched for academic publications, and Thư Viện Pháp Luật, a proprietary database of Vietnamese government documents, and the Vietnam Electronic Health Administration website were searched for government documents. Google Scholar and Google Search were used for snowballing searches. The sources were assessed against predefined eligibility criteria through title, abstract, and full-text screening. Relevant information from the included sources was charted and summarized. The review process was primarily undertaken by one researcher and reviewed by another researcher during each step.
In total, 11 academic publications and 20 government documents were included in this review. Among the academic studies, 5 reported engineering solutions for information systems in hospitals, 2 assessed readiness for EHR implementation, 1 tested physicians' performance before and after using clinical decision support software, 1 reported a national laboratory information management system, and 2 reviewed the health system's capability to implement eHealth and artificial intelligence. Of the 20 government documents, 19 were promulgated from 2013 to 2020. These regulations and guidance cover a wide range of digital health domains, including hospital information management systems, general and interoperability standards, cybersecurity in health organizations, conditions for the provision of health information technology (HIT), electronic health insurance claims, laboratory information systems, HIT maturity, digital health strategies, electronic medical records, EHRs, and eHealth architectural frameworks.
Research about hospital-based digital health systems in Vietnam is very limited, particularly implementation studies. Government regulations and guidance for HIT in health care organizations have been released with increasing frequency since 2013, targeting a variety of information systems such as electronic medical records, EHRs, and laboratory information systems. In general, these policies were focused on the basic specifications and standards that digital health systems need to meet. More research is needed in the future to guide the implementation of digital health care systems in the Vietnam hospital setting.
