Colorectal cancer (CRC) is one of the most prevalent causes of cancer-related fatalities globally, and its development is closely associated with dietary and microbial factors. The aim of this study was to investigate the potential of ganjang, a traditional fermented soy sauce, in alleviating colitis-associated colorectal cancer (CAC) in a mouse model induced by azoxymethane/dextran sulfate sodium (AOM/DSS). The bacterial composition of ganjang samples from different regions primarily included spp.

Aims: Osteoarthritis (OA) is a chronic joint disorder marked by cartilage breakdown, bone alterations, and inflammation, leading to significant pain and disability. Current therapeutic strategies, ranging from lifestyle interventions to pharmacological and surgical treatments, offer limited efficacy and are often accompanied by side effects. This study investigates the potential of Polydioxanone (PDO), a biocompatible synthetic polymer, as a novel intra-articular (IA) viscosupplement in OA.

Article Synopsis
  • IL-32γ plays a crucial role in inhibiting growth and migration of liver cancer cells (HepG2 and Hep3B) while inducing autophagy, as shown by increased LC3 and related markers.
  • Through big data analysis, the study revealed that IL-32γ overexpression reduces the expression of MET and mTOR, which are important for tumor growth regulation.
  • In vivo experiments confirmed that IL-32γ overexpression leads to suppressed liver tumor growth and correlates with autophagy induction in human liver tumor samples.

  • Chronic fatigue syndrome (CFS) significantly impacts the quality of life for working-age individuals, but there has been limited research on effective treatments for this group.
  • This study assessed the effects of a herbal supplement mixture (CAA) on muscle fatigue and endurance in a double-blind, placebo-controlled trial with 80 participants over 8 weeks.
  • Results showed that those taking CAA experienced significant improvements in fatigue levels and physical endurance compared to the placebo group, indicating a potential benefit of herbal supplements for managing chronic fatigue.

Background: Walking is widely recognized as a prevalent form of daily exercise worldwide. However, fewer studies have explored the health outcomes of different intensities of walking exercise for older adults. Thus, the study aimed to investigate the effects of walking at different exercise intensities on body composition, emotions, cognition, and physical function among older adults.

The prognosis of early gastric cancer (EGC) patients is associated with lymph node metastasis (LNM). Considering the relatively high rate of LNM in T1b EGC patients, it is crucial to determine the factors associated with LNM. In this study, we constructed and validated predictive models based on machine learning (ML) algorithms for LNM in patients with T1b EGC.

The calculation of the electrical charge transport properties of alkanes with ( = 4-11) was performed to understand the odd-even effect on its current-voltage response. The extended molecule and broadband limit models were used to describe the molecular junction and covalent coupling with the electrodes. It was shown that among the participating molecular orbitals, HOMO and HOMO-1 are the ones with the most charge transport contribution.

Background: As a relatively novel approach to enhancing skeletal muscle health, mixed protein supplementation has shown similar responses to whey protein. However, no previous studies have examined its impact on golf swing performance. This study aimed to examine the effect of mixed protein supplementation on the swing performance and muscle strength of casual golfers.

This study compared the surgical outcomes and long-term prognosis of intracorporeal and extracorporeal esophagojejunostomy after laparoscopic total gastrectomy (LTG) for gastric cancer patients. In total 228 clinical stage I gastric cancer patients undergoing LTG were enrolled from January 2012 and December 2022. Each case in the totally laparoscopic total gastrectomy (TLTG) group was 1:1 propensity score-matched to control cases in the laparoscopy-assisted total gastrectomy (LATG) group.

Background: Sarcopenia is a muscle-wasting condition that affects older individuals. It can lead to changes in movement patterns, which can increase the risk of falls and other injuries.

Methods: Older women participants aged ≥65 years who could walk independently were recruited and classified into two groups based on knee extension strength (KES).

Purpose: This study was performed to assess the lifestyle-related behaviors of patients with gastric cancer (GC) and to investigate the associations between the time since GC diagnosis and these behaviors.

Materials And Methods: This study included 29,478 adults (including 338 patients with GC) aged ≥ 40 years who participated in the Korea National Health and Nutrition Examination Survey 2014-2021. Multiple logistic regression analysis explored the associations between the time since GC diagnosis (patients diagnosed with GC less than 5 years ago [<5 years group] and those diagnosed with GC 5 or more than years ago [≥5 years group]) and lifestyle factors.

Inflammatory bowel disease (IBD), characterized by chronic inflammation of the gut, is caused by several factors. Among these factors, microbial factors are correlated with the gut microbiota, which produces short-chain fatty acids (SCFAs) via anaerobic fermentation. Fermented foods are known to regulate the gut microbiota composition.

Background: Researchers have investigated the physical and psychosocial advantages of Taekwondo for older adults. However, prior studies of Taekwondo's impact on physical function and psychological well-being in this demographic have produced inconsistent findings. Thus, this systematic review aimed to assess how Taekwondo practice affects the physical function and psychological well-being of older adults.

Sarcopenic obesity (SO) is characterized by concomitant sarcopenia and obesity and presents a high risk of disability, morbidity, and mortality among older adults. However, predictions based on sequential neural network SO studies and the relationship between physical fitness factors and SO are lacking. This study aimed to develop a predictive model for SO in older adults by focusing on physical fitness factors.

Article Synopsis
  • The study explored how face masks impact physiological responses while exercising, focusing on differences between physically active and sedentary college students.
  • Results showed that while physically active individuals initially had better peak oxygen uptake (VO2peak), this advantage diminished when face masks were worn during exercise.
  • The use of face masks significantly decreased exercise tolerance and breathing efficiency more in active participants compared to sedentary ones, highlighting the need to consider individual fitness levels when using face masks.

Background: Echocardiography is widely used to evaluate left ventricular (LV) diastolic function in patients suspected of heart failure. For patients in sinus rhythm, a combination of several echocardiographic parameters can differentiate between normal and elevated LV filling pressure with good accuracy. However, there is no established echocardiographic approach for the evaluation of LV filling pressure in patients with atrial fibrillation.

Background: The association between common neuroradiological markers of multiple sclerosis (MS) and clinical disability is weak. Given that the disability in patients with MS may depend on the underlying structural connectivity of the brain, our study aimed to examine the association between white matter tracts affected by MS and the patients' disability using a new tract density index (TDI).

Method: This study included 53 patients diagnosed with MS, examined between 2019 and 2020.

Article Synopsis
  • Percutaneous mitral valvuloplasty (PMV) is an effective treatment for patients with severe rheumatic mitral stenosis (RMS), but the impact of changes in mitral valve area (∆MVA) during the procedure is not well understood.
  • A study analyzed 308 patients from the MASTER registry, focusing on those undergoing their first PMV, and found that a ∆MVA greater than 0.5 cm² correlated with better long-term health outcomes.
  • The research indicates that not only achieving optimal post-procedure results but also aiming for a significant increase in ∆MVA could improve patient prognosis in PMV surgeries.

Background And Objectives: Leptomeningeal metastases (LMs) are neoplasms that proliferate to membranes lining the brain and spinal cord. Intra-CSF methotrexate (MTX) chemotherapy is a prevalent treatment option. However, resultant long-term neurotoxicity can lead to irreversible disseminated necrotizing leukoencephalopathy (DNL).
