Aerobic bacterial group as an early-stage biomarker from faecal samples of patients with colorectal cancer without distant metastasis.

The current approaches for detecting most colorectal polyps and early neoplasms lack sufficient sensitivity and specificity, potentially hindering treatment and ultimately reducing survival rates. Here, we performed a metagenomic analysis to identify microbiome markers in stool samples from patients with early-stage colorectal cancer (CRC). We compared the composition of gut microbiota between patients with CRC and healthy individuals, specifically focusing on patients with early-stage CRC, defined as those without core mutations (KRAS, BRAF) for CRC diagnosis, stable microsatellite instability, and distant metastasis.

Sex differences in the impact of ventricular-arterial coupling on left ventricular function in patients with hypertension.

Increased arterial stiffness elevates aortic load, which can have adverse impacts on left ventricular (LV) function and contribute to the onset of heart failure. This impact is known to be more pronounced in women. Optimal coordination between ventricular contraction and the arterial system is required to maintain efficient cardiac function.

Effects of dietary fatty acid on all-cause mortality according to the kidney function based on the nationwide population study.

Background: Although the relationship between fatty acids (FAs) and the risk of all-cause mortality has been long discussed, there is little evidence about the impact of each FA component on all-cause mortality by kidney function status.

Methods: We used data from the U.S.

Post-hoc analysis of the CARES trial suggests delayed progression of chronic kidney disease in patients with gout during urate-lowering therapy.

Based on the hypothesis that hyperuricemia is a modifiable risk factor for chronic kidney disease (CKD) progression, there is an expectation that urate-lowering therapy (ULT) could delay the progression of CKD. Here, we investigated changes in kidney function and the association of the serum uric acid (sUA) level and kidney function during ULT in patients with gout. To do this we conducted post-hoc analysis on patients who received ULT with either febuxostat or allopurinol for more than six months in the CARES trial.

Associations of Retinal Vessel Geometry and Optical Coherence Tomography Angiography Metrics With Choroidal Metrics in Diabetic Retinopathy.

Purpose: To elucidate the mechanism underlying changes in choroidal metrics (choroidal thickness [CT], choroidal vascularity index [CVI], and choriocapillaris [CC] flow deficit [FD]) observed in diabetic retinopathy (DR) and examine the association of choroidal metrics with both retinal vessel geometry and optical coherence tomography angiography (OCTA) metrics.

Methods: Overall, 133 eyes of 133 patients were analyzed retrospectively. Retinal vessel geometry parameters were assessed using semiautomated software.

Discrepancies between home blood pressure and ambulatory blood pressure monitoring in apparent treatment-resistant hypertension: analysis from the Korean resistant hypertension cohort.

This study aimed to investigate the characteristics of out-of-office blood pressure (BP) measurements in patients with apparent treatment-resistant hypertension (aRH) enrolled from 15 tertiary care centers in South Korea. aRH was defined as having uncontrolled office BP ≥ 130/80 mmHg despite receiving three classes of antihypertensive medication or any level of BP despite receiving ≥4 classes of antihypertensive medication. Patients with complete data for office BP, 24-h ambulatory BP monitoring (ABPM), and home BP measurements at baseline were included.

Micronutrient Deficiency and Muscular Status in Inflammatory Bowel Disease.

Micronutrient deficiencies are common in inflammatory bowel disease (IBD). The aim of this study was to evaluate micronutrient deficiencies and identify muscular status of patients with IBD. From June 2019 to October 2021, a total of 105 patients with IBD were enrolled prospectively.

Identification of Novel Genetic Loci Affecting Age at Onset of Parkinson's Disease: A Genome-wide Association Study.

Background: The age at onset (AAO) of Parkinson's disease (PD) varies widely among individuals and significantly influences disease progression and prognosis. However, few genome-wide association studies (GWASs) have investigated genetic variants determining AAO, particularly in East Asian populations.

Objectives: To identify single-nucleotide polymorphisms (SNPs) affecting AAO of PD in Korean patients.

Understanding Standard Procedure in Auditory Brainstem Response: Importance of Normative Data.

The auditory brainstem response (ABR) is a noninvasive test that measures neural activity in response to auditory stimuli. Racial differences in head shape have provided strong evidence for specific normative data and accurate device calibration. International standards emphasize the need for standardized procedures and references.

TGFβ2-Driven Ferritin Degradation and Subsequent Ferroptosis Underlie Salivary Gland Dysfunction in Postmenopausal Conditions.

Despite the high incidence of dry mouth in postmenopausal women, its underlying mechanisms and therapeutic interventions remain underexplored. Using ovariectomized (OVX) mouse models, here this study identifies ferroptosis, an iron-dependent regulated cell death, as a central mechanism driving postmenopausal salivary gland (SG) dysfunction. In the OVX-SGs, TGFβ signaling pathway is enhanced with the aberrant TGFβ2 expression in SG mesenchymal cells.

Safety and efficacy of Mg-Dy membrane with poly-L-lactic acid coating for guided bone regeneration.

The aim of this study was to evaluate safety and efficacy of a poly-L-lactic acid (PLLA)-coated magnesium (Mg)-Dysprosium (Dy) membrane in guided bone regeneration (GBR) using a rabbit calvarium model. The microstructure of the Mg-Dy membrane surface and thickness of the PLLA coating were examined. In vitro degradation and cytotoxicity test was conducted.

Will Mobile-Bearing Total Knee Arthroplasty Be Lost to History? A Comparative Study of Long-Term Follow-Up.

Mobile-bearing (MB) total knee arthroplasty (TKA) implants were introduced as an alternative to fixed-bearing (FB) implants because of their theoretical advantages related to femorotibial rotational mismatch. The purpose of this study is to compare the clinical and radiologic outcomes of MB and FB TKA after approximately 13 years of follow-up. We compared the results of 88 patients with a mean age of 66 years who had received a rotating platform MB implant or a FB implant.

The Significance of an Initial Controlling Nutritional Status Score in Predicting the Functional Outcome, Complications, and Mortality in a First-Ever Ischemic Stroke.

Background And Purpose: Nutritional status can influence the outcomes and mortality of various diseases. The association between initial nutritional status and ischemic stroke outcomes, however, remains poorly understood. This study investigated whether the Controlling Nutritional Status (CONUT) score at admission could predict functional recovery, complications, and survival following an ischemic stroke.

Advantages of single high-dose radiation therapy compared with conventional fractionated radiation therapy in overcoming radioresistance.

Background: Radioresistance is a major clinical challenge in cancer treatment, as it reduces the effectiveness of radiation therapy (RT). While advances in radiation delivery have enabled the clinical use of high-dose hypofractionated RT, its impact on radioresistant tumors remains unclear. This study aimed to compare the effects of single high-dose RT with conventional fractionated RT on radioresistant breast cancer cells and explore the underlying mechanisms.

Methods: This is a cross-sectional study using baseline data from the 10-year ongoing cohort study named KNOW-PedCKD (Korean Cohort Study for Outcome in Patients with Pediatric Chronic Kidney Disease).

Curve-centered plaques raise the risk of peri-operative neurological and cardiovascular complications during angioplasty and stenting for severe carotid stenosis.

Introduction: Carotid artery stenting is an alternative interventional treatment to carotid endarterectomy. However, preprocedural considerations and anatomical risk factor analyses for carotid artery stenting are currently insufficient. Therefore, we investigated the high-risk anatomical appearance of carotid artery stenting from the neurointerventionist perspective to predict periprocedural complications.
