The THYCA-QoL 24 is a specific instrument designed to measure health-related quality of life (HRQoL) in patients with thyroid cancer (TC). This study aimed to evaluate the Vietnamese version of the THYCA-QoL (acceptability, validity, and reliability) and use this validated version to systematically assess longitudinal changes in HRQoL in this patient population before and after thyroidectomy, including adjuvant radioactive iodine (RAI) therapy to understand the impact of surgical intervention over time. The study was conducted in three steps: translation, validation, and evaluation of the THYCA-QoL questionnaire for the Vietnamese population.

Introduction: This study examines the genetic and clinical profiles of Vietnamese patients with non-small cell lung cancer (NSCLC), focusing on mutations in seven driver genes: , , , , , , and . The goal is to identify mutation patterns and their correlations with clinical factors, thereby informing personalized treatment strategies.

Materials And Methods: A cross-sectional study of 299 NSCLC patients at the University Medical Center, Ho Chi Minh City (2019-2022) recorded demographics, smoking history, and tumor stage.

Vaginitis is a prevalent gynecological condition that impacts women's quality of life, with most women likely to experience it at least once. Traditional diagnosis involves manually observing vaginal discharge samples under a microscope. This process relies heavily on the technician's expertise and is vulnerable to subjective biases.

Background: The possible association between diabetes mellitus and dementia has raised concerns, given the observed coincidental occurrences.

Objective: This study aimed to develop a personalized predictive model, using artificial intelligence, to assess the 5-year and 10-year dementia risk among patients with type 2 diabetes mellitus (T2DM) who are prescribed antidiabetic medications.

Methods: This retrospective multicenter study used data from the Taipei Medical University Clinical Research Database, which comprises electronic medical records from 3 hospitals in Taiwan.

Purpose: In recent years, laparoscopic near-total gastrectomy (LnTG) has emerged as a surgical option for gastric cancer in the middle-third of the stomach. However, its application in locally advanced stages presents technical challenges. This study aims to provide a detailed analysis of the operative outcomes and long-term functional and oncological results of totally LnTG in combination with D2 lymphadenectomy for middle-third gastric cancer.

Article Synopsis
  • Lymph node metastasis can occur in early gastric cancer, even in nodes not near the primary tumor, necessitating careful selection between total gastrectomy (TG) and subtotal gastrectomy (sTG) based on cancer spread.
  • A study of 98 patients revealed that 65.3% had metastatic lymph nodes, with higher rates of metastasis increasing with tumor invasion depth, especially in adjacent lymph node stations.
  • Results showed that while TG had higher total lymph nodes and positive lymph node rates, the ratio of metastatic lymph nodes was similar between TG and sTG, suggesting that sTG with proper lymphadenectomy is a viable treatment option for certain early-stage gastric cancers.

Background: This study investigated post-traumatic stress disorder (PTSD), anxiety, depression and their related factors among coronavirus disease 2019 (COVID-19) patients during the fourth wave of the pandemic in Vietnam.

Methods: Vietnamese-fluent confirmed COVID-19 patients for at least 3 d were recruited in this online cross-sectional study to answer a three-part questionnaire including participants' sociodemographic characteristics, PTSD (Impact of Event Scale-Revised) and anxiety and depression (Hospital Anxiety and Depression Scale). Associated factors were determined using multivariable binary logistic regression models.

Diagnosis of hepatocellular carcinoma (HCC) in early-stage, to give an effective treatment option and improve quality of life for cancer patients, is an important medical mission globally. Combination of AFP with some biomarkers may be more supportive in both diagnosis and screening of HCC, but the range value of these markers can be applied as daily markers were unclearly. In some studies, human telomerase reverse transcriptase (hTERT mRNA) was reported as an advantage marker to diagnose cancer.

Identification of tumor-derived mutation (TDM) in liquid biopsies (LB), especially in early-stage patients, faces several challenges, including low variant-allele frequencies, interference by white blood cell (WBC)-derived mutations (WDM), benign somatic mutations and tumor heterogeneity. Here, we addressed the above-mentioned challenges in a cohort of 50 nonmetastatic colorectal cancer patients, via a workflow involving parallel sequencing of paired WBC- and tumor-gDNA. After excluding potential false positive mutations, we detected at least one TDM in LB of 56% (28/50) of patients, with the majority showing low-patient coverage, except for one TDM mapped to that recurred in 30% (15/30) of patients.

Aim: This study measured the level of knowledge, attitudes and practices towards COVID-19 prevention and examined associated factors among patients at a national tertiary general hospital in Vietnam.

Methods: Adult patients admitted to University Medical Center during research period were recruited in a cross-sectional study, which employed a convenience sampling method with a 4-component questionnaire in order to examine the patients' consciousness towards COVID-19 spreading prevention based on four aspects: demographic characteristics (10 items), knowledge (14 items), attitudes (6 items), and practices (7 items).

Results: The study involved 2769 respondents (18-90 years) with the mean age of 38.

Background: The dynamic obstruction of the left ventricular outflow tract (LVOT) is a well-known complication in mitral annuloplasty but rarely seen in nonmitral cardiovascular surgery. The dynamic LVOT obstruction can lead to hemodynamic instability, even shock and the treatment is significantly different from the standard approach. .
