An exploratory multi-omics study reveals distinct molecular signatures of ulcerative colitis and Crohn's disease and their correlation with disease activity.

Clinically heterogeneous spectrum and molecular phenotypes of inflammatory bowel disease (IBD) remain to be comprehensively elucidated. This exploratory multi-omics study investigated the serum molecular profiles of Crohn's disease (CD) and ulcerative colitis (UC), in association with elevated fecal calprotectin and disease activity states. The serum proteome, metabolome, and lipidome of 75 treated IBD patients were profiled.

DPAR: Decoupled Graph Neural Networks with Node-Level Differential Privacy.

Graph Neural Networks (GNNs) have achieved great success in learning with graph-structured data. Privacy concerns have also been raised for the trained models which could expose the sensitive information of graphs including both node features and the structure information. In this paper, we aim to achieve node-level differential privacy (DP) for training GNNs so that a node and its edges are protected.

Changes in the Epidemiology of Thoracic and Cardiovascular Diseases in Korea During the COVID-19 Pandemic: A Nationwide Analysis.

There is limited evidence regarding the impact of the coronavirus disease 2019 (COVID-19) pandemic on the epidemiology of thoracic and cardiovascular diseases. This study aimed to investigate changes in medical visits for these conditions during the COVID-19 pandemic. We analyzed the entire Korean population (~50 million) for monthly medical visits for 15 common thoracic and cardiovascular conditions, including pneumothorax, large bullae, lung cancer, esophageal cancer, thymoma, empyema, mediastinitis, esophageal rupture, multiple rib fractures, hemothorax, rib mass, varicose vein, pectus excavatum, aortic dissection, aortic aneurysm, and valve disease from January 2019 to December 2021.

Smart Packaging with Disposable NFC-enabled Wireless Gas Sensors for Monitoring Food Spoilage.

Gas sensors present an alternative to traditional off-package food quality assessment, due to their high sensitivity and fast response without the need of sample pretreatment. The safe integration of gas sensors into packaging without compromising sensitivity, response rate, and stability, however, remains a challenge. Such packaging integration of spoilage sensors is crucial for preventing food waste and transitioning toward more sustainable supply chains.

Anterior-to-Central Cartilage Defects of Arthritic Knee Showed Better Cartilage Regeneration Than Posterior Cartilage Defects Using Mesenchymal Stem Cell Implantation.

Purpose: To analyze cartilage regeneration and clinical outcomes after human umbilical cord blood-derived mesenchymal stem cell (hUCB-MSCs) implantation on the basis of the distribution and location of medial femoral condyle (MFC) cartilage defects.

Methods: Patients who underwent hUCB-MSC implantation for MFC cartilage defects involved in isolated medial compartment osteoarthritis were included. The patients were divided into 2 groups, those with MFC defects located within the anterior-central portion (group A) and those with MFC defects extending to the posterior portion (group P).

Integrative multi-omics analysis to gain new insights into COVID-19.

Multidimensional host and viral factors determine the clinical course of COVID-19. While the virology of the disease is well studied, investigating host-related factors, including genome, transcriptome, metabolome, and exposome, can provide valuable insights into the underlying pathophysiology. We conducted integrative omics analyses to explore their intricate interplay in COVID-19.

Polyhexamethylene Guanidine Phosphate Induces Restrictive Ventilation Defect and Alters Lung Resistance and Compliance in Mice.

Polyhexamethylene guanidine phosphate (PHMG-p), a major ingredient of humidifier disinfectants, is known to induce inflammation, interstitial pneumonitis, and fibrosis in the lungs. While its histopathologic toxicities have been studied in rodents, research on pulmonary function test (PFT) changes following PHMG-p exposure is limited. This study aimed to investigate the acute and chronic effects, as well as the dose and time response, of PHMG-p on the lungs in mice using PFT and histopathologic examinations.

Advancements and limitations in polygenic risk score methods for genomic prediction: a scoping review.

This scoping review aims to identify and evaluate the landscape of Polygenic Risk Score (PRS)-based methods for genomic prediction from 2013 to 2023, highlighting their advancements, key concepts, and existing gaps in knowledge, research, and technology. Over the past decade, various PRS-based methods have emerged, each employing different statistical frameworks aimed at enhancing prediction accuracy, processing speed and memory efficiency. Despite notable advancements, challenges persist, including unrealistic assumptions regarding sample sizes and the polygenicity of traits necessary for accurate predictions, as well as limitations in exploring hyper-parameter spaces and considering environmental interactions.

Circulating Phylloquinone and the Risk of Four Female-Specific Cancers: A Mendelian Randomization Study.

Background: Observational studies have linked vitamin K and cancer, but the causality of this association remains unknown. This Mendelian randomization (MR) study aims to investigate the association between circulating phylloquinone (vitamin K) levels and four female-specific cancers.

Methods: We used four single-nucleotide polymorphisms (SNPs) to instrument phylloquinone, with the reported F-statistic 16.

Molecular mechanism of skeletal muscle loss and its prevention by natural resources.

A skeletal muscle disorder has drawn attention due to the global aging issues. The loss of skeletal muscle mass has been suggested to be from the reduced muscle regeneration by dysfunction of muscle satellite cell/fibro-adipogenic progenitor cells and the muscle atrophy by dysfunction of mitochondria, ubiquitin-proteasome system, and autophagy. In this review, we highlighted the underlying mechanisms of skeletal muscle mass loss including Notch signaling, Wnt/β-catenin signaling, Hedgehog signaling, AMP-activated protein kinase (AMPK) signaling, and mammalian target of rapamycin (mTOR) signaling.

Dietary effects of protected fat, soybean meal, and heat-treated soybean meal on performance, physiological parameters, and behavioral measurements of early-fattening Hanwoo steers under heat stress conditions.

Objective: This study evaluated the effects of increased levels of dietary total digestible nutrient (TDN) and crude protein (CP) using protected fat (PF), soybean meal (SB), and heat-treated soybean meal (HSB) on performance, physiological parameters, and behavioral measurements of early-fattening Hanwoo steers under heat stress conditions.

Methods: Thirty-six steers (480.9±58.

The role of diagnostic monocular occlusion test in basic type intermittent exotropia.

To assess the response to monocular occlusion test in basic type intermittent exotropia (IXT) and to evaluate the surgical outcomes of titrated surgery based on the test's result. Medical records were retrospectively reviewed for patients who underwent bilateral lateral rectus recession for basic type IXT. Patients were categorized into two groups: those who underwent a preoperative diagnostic monocular occlusion test (occlusion group) and those who did not (no occlusion group).

Successful 24-hour discharge for total knee arthroplasty: importance of timing of surgery and physiotherapy in enhanced recovery after surgery protocol.

Introduction: The current literature is mixed on which patient factors, if any, predict the rate of successful discharge within 24 h of enhanced recovery after surgery (ERAS) total knee arthroplasty (TKA). This study aimed to investigate the influence of timing of surgery and physiotherapy on the rate of successful 24-h discharge.

Methods: All 342 patients who underwent ERAS day surgery TKA from August 2020 to July 2021 were followed up prospectively.

Feasibility of estimating tidal volume from electrocardiograph-derived respiration signal and respiration waveform.

Purpose: Estimating tidal volume (V) from electrocardiography (ECG) can be quite useful during deep sedation or spinal anesthesia since it eliminates the need for additional monitoring of ventilation. This study aims to validate and compare V estimation methodologies based on ECG-derived respiration (EDR) using real-world clinical data.
