Objective: Machine learning (ML) is increasingly employed to diagnose medical conditions, with algorithms trained to assign a single label using a black-box approach. We created an ML approach using deep learning that generates outcomes that are transparent and in line with clinical, diagnostic rules. We demonstrate our approach for autism spectrum disorders (ASD), a neurodevelopmental condition with increasing prevalence.

Article Synopsis
  • - The study investigated multidrug-resistant (MDR) Agona infections from food-producing animals in South Korea, specifically focusing on 209 isolates predominantly found in chickens, pigs, cattle, and ducks from 25 slaughterhouses between 2010 and 2020.
  • - Findings revealed that chicken Agona isolates had a high resistance rate (69-83%) to several antibiotics and exhibited significantly greater levels of MDR compared to isolates from cattle and pigs.
  • - Molecular analysis identified 23 types of Agona isolates, with two major types (P1-III-2-13 and P1-IV-2-13) being most prevalent, and a dominant sequence type (ST13) found primarily in chickens, indicating a potential public health

Background: The enhanced recovery after surgery (ERAS) protocols have been consistently associated with improved patient experience and surgical outcomes. Despite the release of ERAS Society guidelines specific to gynecologic oncology, the adoption of ERAS in gynecology on global level has been disappointingly low and some centers have shown minimal improvement in clinical outcomes after adopting ERAS. The aim of this study is to describe the development and early experience of ERAS protocols in gynecologic surgery at an urban academic tertiary medical center.

The production of β-lactamase by nontyphoidal has become a public health issue throughout the world. In this study, we aimed to investigate the antimicrobial resistance profiles and molecular characteristics of β-lactamase-producing serovar Albany isolates. A total of 434 Albany were obtained from feces and carcasses of healthy and diseased food-producing animals [cattle ( = 2), pigs ( = 3), chickens ( = 391), and ducks ( = 38)] during 2013-2020.

Article Synopsis
  • A total of 836 microbial isolates were collected from dogs (695) and cats (141) suffering from various infections between 2018 and 2019, highlighting an increased prevalence of drug-resistant pathogens.
  • Resistance rates to cefovecin and enrofloxacin were notably higher in dogs (18.1% and 22.9%) compared to cats (12.1% and 12.8%), with 10.8% of the isolates exhibiting resistance to both antimicrobials.
  • The study identified specific genetic markers and mutations associated with resistance, indicating a public health concern due to the detection of the pandemic ST131 strain in these companion animals.

Extended-spectrum β-lactamase (ESBL)-producing serovar Enteritidis has emerged as a public health concern. The main objectives of this study were therefore to determine the antimicrobial susceptibility profiles of Enteritidis and to investigate the molecular characteristics of identified ESBL-producing isolates. In the study, 237 Enteritidis isolates (232 isolates from chickens, 4 from cattle, and 1 from a pig) were recovered from carcasses and fecal samples of healthy and diseased food animals between 2010 and 2017.

The emergence of bacterial infections in companion animals is a growing concern as humans can also be infected through the transmission of pathogenic bacteria. Because there have been few studies conducted on companion animals, the extent and significance of prevalence in veterinary practices remain unknown. This is the first nationwide surveillance report aimed at elucidating the prevalence pattern and associated infections of isolated bacteria from dogs in Korea.

Contamination of meat with antimicrobial-resistant bacteria represents a major public health threat worldwide. In this study, we determined the antimicrobial resistance profiles and resistance trends of isolated from major food animal carcasses (408 cattle, 1196 pig, and 1312 chicken carcass isolates) in Korea from 2010 to 2018. Approximately 75%, 92%, and 77% of cattle, pig, and chicken carcass isolates, respectively, were resistant to at least one antimicrobial agent.

Colistin is considered the last resort for the treatment of multi-drug resistant Gram-negative bacterial infections. We studied colistin resistance and the gene carriage in isolates recovered from food animals in South Korea between 2010 and 2018. Colistin resistance was found in 277 isolates, predominantly in Enteritidis (57.

Article Synopsis
  • The study assessed the effectiveness of universal SARS-CoV-2 screening in intensive care units (ICUs) to prevent the transmission of the virus and reduce anxiety among healthcare personnel (HCP).* -
  • Conducted over 7 weeks in two ICUs, the study found no positive cases of SARS-CoV-2 among 142 patients, and only 2 out of 86 HCP sought consultation for possible infection.* -
  • The findings suggest that the screening program, in conjunction with other safety measures, effectively reduced the risk of in-hospital transmission and helped maintain stability in clinical practices for HCP during the pandemic.*

Purpose: Cancer survivors frequently experience cancer or treatment-related symptoms and functional morbidities that can be addressed through rehabilitation services, but these symptoms often go unnoticed and seldom managed. This study seeks to investigate the undetected patient symptoms and functional loss related to the activities of daily living (ADLs) in ovarian cancer patients during chemotherapy and to identify the influence of chemotherapy on such loss.

Methods: Ovarian cancer patients undergoing chemotherapy were identified from June to August 2016, who were treated at the department of Gynecology and Obstetrics of two tertiary hospitals.
