Background: COVID-19, caused by the SARS-CoV-2 virus, presents with varying severity among individuals. Both viral and host factors can influence the severity of acute and chronic COVID-19, with chronic COVID-19 commonly referred to as long COVID. SARS-CoV-2 infection can be properly diagnosed by performing real-time reverse transcription PCR analysis of nasal swab samples.

Article Synopsis
  • This study investigated the links between childhood exposure to bisphenol A (BPA) and parabens (PBs) and their impact on oxidative stress and cochlear function in children with hearing loss (HL) by measuring various urinary biomarkers and distortion product otoacoustic emissions (DPOAEs).
  • A total of 641 children participated, and results indicated that about 14.2% had HL, showing significant negative correlations between BPA/PB exposure and outer hair cell (OHC) activity, particularly at certain frequencies.
  • The findings suggest that exposure to these chemicals particularly affects OHC function at middle frequencies, potentially contributing to hearing loss in children.

Background: In primary health care, the dissemination of retracted publications through literature reviews, guidelines, and recommendations can have a significant and lasting impact. Despite this potential threat, the retraction consequences and patterns in this domain have not been extensively explored. Therefore, this study investigates the characteristics and ripple effects of retracted papers in primary health care literature.

  • Genetic variations in individuals may affect how long vaccine-induced immunity against COVID-19 lasts, which is crucial for vaccination policies.
  • A study involving 1,119 participants from Taiwan analyzed genetic samples and found several significant gene variants linked to breakthrough COVID-19 infections after mRNA vaccination.
  • The results indicated that people with higher polygenic risk scores were more likely to experience breakthrough infections, suggesting a need for personalized vaccination strategies based on genetic profiles.

Progesterone (P) plays a pivotal role in regulating the cancer progression of various types, including breast cancer, primarily through its interaction with the P receptor (PR). In PR-negative breast cancer cells, P appears to function in mediating cancer progression, such as cell growth. However, the mechanisms underlying the roles of P in PR-negative breast cancer cells remain incompletely understood.

The BOOST (Booster promotion for older outpatients using SMS text reminders) program at Taipei Veterans General Hospital assessed the effectiveness of text message reminders in enhancing COVID-19 booster vaccination rates among the elderly, guided by the Health Belief Model (HBM). Targeting patients aged 65 and above, eligible yet unvaccinated for a COVID-19 booster, this cohort study sent personalized reminders a week prior to their scheduled appointments between April 18, 2022, and May 12, 2022, acting as cues to action to enhance vaccination uptake by overcoming perceived barriers and raising awareness of benefits. Over 5 weeks, the study observed a 38% increase in vaccination rate among 3,500 eligible patients, markedly surpassing the concurrent national rate increase of 4% for the same demographic.

Introduction: The clinical presentations of dry eye disease (DED) and depression (DEP) often comanifest. However, the robustness and the mechanisms underlying this association were undetermined.

Objectives: To this end, we set up a three-segment study that employed multimodality results (meta-analysis, genome-wide association study [GWAS] and Mendelian randomization [MR]) to elucidate the association, common pathways and causality between DED and DEP.

Respect for patient autonomy is paramount in resolving ethical tensions in end-of-life care. The concept of relational autonomy has contributed to this debate; however, scholars often use this concept in a fragmented manner. This leads to partial answers on ascertaining patients' true wishes, meaningfully engaging patients' significant others, balancing interests among patients and significant others, and determining clinicians' obligations to change patients' unconventional convictions to enhance patient autonomy.

  • Researchers looked into how well ChatGPT, a type of smart computer program, helps nursing students study for their exams.
  • * The study checked how accurately ChatGPT answered questions from Taiwan's nursing licensing exam and what made some questions harder for it.
  • * ChatGPT got about 80.75% of the answers right overall, but it did better on General Medicine questions than on others like Basic Nursing.

This study evaluates the incidence and characteristics of adverse events (AEs) following the second COVID-19 booster dose, leveraging Taiwan's distinctive approach of extending booster vaccinations to all citizens, unlike the targeted high-risk group strategies in other countries. Utilizing data from Taipei Veterans General Hospital's Vaccine Adverse Event Reporting System (VAERS) from 27 October 2022 to 19 January 2023, this research examines AEs in 441 out of 1711 booster recipients, considering factors like age, vaccine brands, and booster combinations. The findings revealed incidence rates (IRs) of 25.

We explored the effect of 3 mg/kg of caffeine supplementation on the cognitive ability and shooting performance of elite e-sports players. Nine e-sports players who had received professional training in e-sports and had won at least eighth place in national-level e-sports shooting competitions. After performing three to five familiarization tests, we employed a single blind, randomized crossover design to divide participants into caffeine trial (CAF) and placebo trial (PL).

We incorporate nuclear quantum effects (NQE) in condensed matter simulations by introducing short-range neural network (NN) corrections to the ab initio fitted molecular force field ARROW. Force field NN corrections are fitted to average interaction energies and forces of molecular dimers, which are simulated using the Path Integral Molecular Dynamics (PIMD) technique with restrained centroid positions. The NN-corrected force field allows reproduction of the NQE for computed liquid water and methane properties such as density, radial distribution function (RDF), heat of evaporation (HVAP), and solvation free energy.

We present a formalism of a neural network encoding bonded interactions in molecules. This intramolecular encoding is consistent with the models of intermolecular interactions previously designed by this group. Variants of the encoding fed into a corresponding neural network may be used to economically improve the representation of torsional degrees of freedom in any force field.

A novel application of conventional Ag nanoparticles (NPs) for metal-enhanced fluorescence (MEF) in cellular imaging is proposed. Different molecular weights of polyethylene glycol (PEG) were tested to determine a suitable spacer on Ag NPs for MEF, and NPs comprising Ag with PEG with a molecular weight of 6000 g (Ag-PEG6k), when present in fluorescein solution, were discovered to cause a 2-fold quantum yield enhancement. For fluorescence imaging of mesenchymal stem cells stained by Alexa Fluor 488, the enhancement factor increased with the Ag-PEG6k NP concentration but decreased with the Alexa Fluor 488 concentration.

  • Surgery is the main treatment for basal cell carcinoma (BCC), but alternatives like radiation or immunotherapy with PD-1 inhibitors like tislelizumab can be effective in some cases.
  • A 74-year-old man was diagnosed with BCC after a mass removal and later found to have squamous lung cancer; his treatment involved chemotherapy and tislelizumab.
  • The treatment led to significant reductions in both the BCC and lung cancer, with the mass disappearing and the wound healing after just two cycles of immunotherapy.
