Background: For the prevention of carbapenem-resistant Enterobacterales (CRE) acquisition in the intensive care unit (ICU), the effectiveness of universal contact precautions (UCP) and chlorhexidine gluconate (CHG) bathing is controversial.
Methods: With the aim of evaluating the effectiveness of UCP and CHG on CRE acquisition, this study was conducted in an ICU at a university-affiliated hospital in Seoul. Beginning in April 2017, all patients admitted to the ICU underwent weekly CRE screening and surveillance tests, and beginning in January 2018, UCP and CHG bathing were implemented for all patients.

The objective of this study was to propose a novel strategy for detecting upper-limb motion intentions from mechanical sensor signals using deep and heterogeneous transfer learning techniques. Three sensor types, surface electromyography (sEMG), force-sensitive resistors (FSRs), and inertial measurement units (IMUs), were combined to capture biometric signals during arm-up, hold, and arm-down movements. To distinguish motion intentions, deep learning models were constructed using the CIFAR-ResNet18 and CIFAR-MobileNetV2 architectures.

Although there are clear guidelines for injection practices to prevent infections, their application in clinical settings is insufficient. Therefore, the objective of this study was to identify factors affecting injection practices associated with reduced infections by conducting surveys targeting practicing healthcare providers involved in administering injections at each healthcare organization and performing data analysis.

In this study, we aimed to investigate the clinical characteristics of and prognostic factors in patients with DFO undergoing amputation.
Methods: This retrospective study involved 101 patients with DFO who underwent amputation.
The emergence of invasive infections attributed to group A (GAS) infections, has resurged since the 1980s. The recent surge in reports of toxic shock syndrome due to GAS in Japan in 2024, while sensationalized in the media, does not represent a novel infectious disease per se, as its diagnosis, treatment, and prevention are already well-established. However, due to signs of increasing incidence since 2011, further research is needed.

A total of 93 feet of 83 consecutive patients with DFI who underwent WBC SPECT/CT for treatment planning were retrospectively analysed. The clinical and SPECT/CT parameters were collected along with the measurements of the maximum standardized uptake value (SUVmax) at DFI.

Due to an increase in interest towards functional and health-related foods, sprout has been in the spotlight since it contains a significant amount of saponins which have anti-cancer, -stress, and -diabetic effects. To increase the amount of production as well as decrease the cultivation period, sprouted ginseng is being studied to ascertain its optimal cultivation environment in hydroponics. Although there are studies on functional components, there is a lack of research on early disease prediction along with productivity improvement.

Granulomatous pneumonia (GPCP) can occur in immunocompromised patients, but has rarely been reported in SOT recipients. The diagnosis of GPCP is difficult since the sensitivity of sputum and bronchoalveolar lavage is low and atypical patterns are shown.

Objective: We investigated gender differences in psychosocial determinants that affect hand hygiene (HH) performance among physicians.
Design: The survey included a structured questionnaire with 7 parts: self-assessment of HH execution rate; knowledge, attitude, and behavior regarding HH; internal and emotional motivation for better HH; barriers to HH; need for external reminders; preference for alcohol gel; and embarrassment due to supervision.
Setting: The study was conducted across 4 academic referral hospitals in Korea.

Background: Hand hygiene (HH) is a fundamental component of infection prevention and control in healthcare settings. This study aimed to identify knowledge, attitude, and barriers to HH according to occupational groups and strategies to increase the rate of HH compliance among healthcare workers (HCWs).
Methods: This cross-sectional survey was conducted in July 2018 at four university-affiliated hospitals.
Background: This study aimed to investigate ventilation strategies to prevent nosocomial transmission of coronavirus disease 2019 (COVID-19).
Methods: We conducted a retrospective epidemiological investigation of a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak in a teaching hospital (February-March 2021). The largest outbreak ward was studied, and measurements were taken to determine the pressure difference and air change per hour (ACH) of the rooms.
Background: Institutional hand hygiene (HH) behavior is difficult to monitor and improve consistently, especially over long periods. This study aimed to investigate the long-term effects of HH promotion activities.
Method: We launched the HH promotion team in 2010 and conducted interventions including goal setting, observation and feedback, education, reward incentives, and accountability.
Background: Infectious disease (ID) specialists are skilled facilitators of medical consultation who promote better outcomes in patient survival, antibiotic stewardship as well as healthcare safety in pandemic response. This study aimed to assess the working status of ID specialists and identify problems faced by ID professionals in Korea.
Methods: This was a nationwide cross-sectional study in Korea.
Human immunodeficiency virus (HIV) continues to be a major public health issue, and the effectiveness of HIV prevention, diagnosis, treatment, and care varies, particularly in the Asia-Pacific region. The rapid initiation of antiretroviral therapy (ART) is important to control the HIV epidemic and to optimize the health of people living with HIV; many guidelines now recommend ART initiation within 7 days of HIV diagnosis, with same-day initiation for people diagnosed with HIV who feel ready. Many countries in the Asia-Pacific region have already implemented or are moving towards implementation of rapid or same-day ART initiation.

In this study, we proposed a deep learning-based Haugh unit (HU) prediction model which is a universal parameter to determine egg freshness using a non-destructively measured weight loss by transfer learning technique. The temperature and weight loss of eggs from a laboratory and real-time cold chain environment conditions are collected from ten different types of room temperature conditions.

Proactively detecting falls and preventing injuries are among the primary keys to a healthy life for the elderly. Near-fall remote monitoring in daily life could provide key information to prevent future falls and obtain quantitative rehabilitation status for patients with weak balance ability. In this study, we developed a deep learning-based novel classification algorithm to precisely categorize three classes (falls, near-falls, and activities of daily living (ADLs)) using a single inertial measurement unit (IMU) device attached to the waist.

Materials And Methods: We aimed to identify cardiovascular risk factors in PLHIV using carotid intima-media thickness (IMT) through a cross-sectional, retrospective cohort study that enrolled 217 PLHIV who underwent carotid IMT measurement at a teaching hospital in Korea. We compared clinical characteristics between PLHIV with subclinical atherosclerosis and PLHIV with IMT within the normal range, and used a receiver operating characteristic curve to determine the cut-off age for predicting subclinical atherosclerosis.
Adequate postural control is maintained by integrating signals from the visual, somatosensory, and vestibular systems. The purpose of this study is to propose a novel convolutional neural network (CNN)-based protocol that can evaluate the contributions of each sensory input for postural stability (calculated a sensory analysis index) using center of pressure (COP) signals in a quiet standing posture. Raw COP signals in the anterior/posterior and medial/lateral directions were extracted from 330 patients in a quiet standing with their eyes open for 20 seconds.
