Background: The associations between thyroid cancer and skeletal outcomes have not been thoroughly investigated. We aimed to investigate the risk of osteoporotic fractures in patients with thyroid cancer compared to that in a matched control group.
Methods: This retrospective cohort study included 2,514 patients with thyroid cancer and 75,420 matched controls from the Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC, 2006-2019).
Background: Continent catheterizable channels (CCC) are a mainstay for reconstruction in patients with neurogenic bladders. Common complications include false passage, channel stenosis/difficult catheterization, channel incontinence, and stomal stenosis. This may result in the need for surgical revision or replacement.

XRD measurements show clear evidence of structural phase transition (SPT) of the LCO thin films from the perovskite (PV) LaCoO to the brownmillerite (BM) LaCoO phases through the intermediate LaCoO phase at a temperature of 350 °C under high-vacuum conditions, ∼10 mbar. The reverse SPT from BM to PV phases is also found under ambient pressure (>100 mbar) of air near 100 °C.

This study describes parent/guardian (caregiver) openness to using AOMs for adolescents with obesity and evaluates factors that may contribute to openness. Caregivers of adolescents aged 12-17 years were surveyed.

Cardiovascular diseases, such as stroke and hypertension, play significant roles in morbidity and mortality rates among the elderly population. In this study, the Reactive Hyperemia Index (RHI) was measured to assess vascular endothelial function and aging-induced pathogenesis of vascular diseases in Korean subjects.

While LNPs are known for their high mRNA delivery efficiency, they can induce excessive immune responses and cause off-target effects, potentially leading to side effects. In this study, we aimed to explore polymer-based mRNA delivery systems as a viable alternative to LNPs, focusing on their mRNA delivery efficiency and potential application in mRNA vaccines.

The adsorption properties of CO on the SrTiO(001) surface were investigated using ambient pressure X-ray photoelectron spectroscopy under elevated pressure and temperature conditions. On the Nb-doped TiO-enriched (1 × 1) SrTiO surface, CO adsorption, i.e.

In this study, we performed expression quantitative trait loci (eQTL) analysis and differential gene expression analysis to detect candidate genes influencing the weight characteristics of 32 castrated Hanwoo cattle across 22 tissues and, we identified variants that affect gene expression levels. In total, we identified a total of 3,298 differentially expressed genes, among which we discovered key genes such as , , , and that have functions related to adipogenesis, body weight, obesity, and lipid metabolism.

While embryonic developmental processes have been extensively researched, many molecular mechanisms regulating the different life stages after birth, such as aging, remain unresolved. We investigated the conserved and global molecular transitions in transcriptional remodeling with age in dogs of 15 breeds, which revealed that genes underlying hormone level regulation and developmental programs were differentially regulated during aging.

We examined the relationship of microparticles and EMPs with adiposity and subclinical CVD risk measures in a pediatric population to determine their potential as biomarkers of CVD risk. Methods and Results A cross-sectional study of youth (n=280; ages 8-20 years) with a range of body mass index categories was used.

Some defects require early and complex surgical intervention and post-operative thromboprophylaxis primarily for valve, conduit, and shunt patency. Antiplatelet and anticoagulant management strategies vary considerably and may or may not align with recognized consensus practice guidelines.

The present study examined functional implications of this process, asking if degeneration impacted the amount of visual recovery attainable from visual restoration training in chronic patients, and if restoration training impacted optic tract (OT) shrinkage.
Methods: Magnetic resonance imaging was used to measure OT volumes bilaterally in 36 patients with unilateral occipital stroke.
1p36 deletion is the most common terminal deletion syndrome in humans. Herein, we report two cases, a 5-month-old female and a 14.5-year-old female, both with 1p36 deletion and left ventricular non-compaction cardiomyopathy.

Left atrial (LA) decompression is not satisfactory even with good function and position of the left ventricular cannula. We describe an alternate approach with LA cannulation via the left atrial appendage (LAA) as a rescue strategy in a patient who had restrictive physiology, in our case was secondary to viral myocarditis acute systolic heart failure with subsequent insidious diffuse endomyocardial fibrosis and superimposed massive calcification, causing inadequate emptying of the left ventricle despite optimal VAD apical cannula position.

The patient underwent planned staged left pneumonectomy for recurrent pneumonias secondary to bronchomalacia followed by orthotopic heart transplantation. This aggressive approach improved the patient candidacy for heart transplantation by removing the source of recurrent infection and respiratory failure (left lung).

Disaster-induced displacement is associated with an increased risk of physical and mental health disorders. We aim to understand (1) the magnitude and pattern of natural disasters, affected-population, and deaths by analyzing the surveillance data by the Emergency Events Database and (2) health outcomes by a systematic review of previous studies (1975-2017), which reported physical or mental health outcomes and epidemiological measure of association among population displaced by natural disasters in Southeast Asia. A total of 674 disasters, mainly floods, storms, and earthquakes, occurred between 2004 and 2017.

Advancements in surgical strategies and techniques along with intensive care management have substantially improved the outcomes of neonatal palliation for SV physiology, particularly for hypoplastic left heart syndrome (HLHS). This is associated with a steady increase in the number of SV patients who are susceptible to develop heart failure (HF) and would potentially require MCS at a certain stage in their palliation.

Also, it has been demonstrated that celastrol has obesity-controlling effects in diet-induced obesity mice. However, direct evidence that celastrol contributes to the development of adipocyte differentiation and lipolysis has not been fully elucidated.
