Background: Interventricular septal (IVS) flattening is a key echocardiographic feature of pulmonary hypertension (PH) that is associated with worse outcomes. The accuracy and interobserver reliability of visual and quantitative measures of IVS in PH patients are poorly described.

Methods: This single-center, retrospective analysis included 173 PH patients.

Background: Pulmonary hypertension (PH) is a leading cause of death in patients with systemic sclerosis (SSc). An important component of SSc patient management is early detection and treatment of PH. Recently the threshold for the diagnosis of PH has been lowered to a mean pulmonary artery pressure (mPAP) threshold of > 20 mmHg on right heart catheterization (RHC).

Cartilage defects and osteoarthritis are health problems which are major burdens on health care systems globally, especially in aging populations. Cartilage is a vulnerable tissue, which generally faces a progressive degenerative process when injured. This makes it the 11th most common cause of global disability.

Introduction: Data on real-world clinical practice and outcomes of patients with pulmonary arterial hypertension associated with connective tissue disease (CTD-PAH) are scarce. The OPUS/OrPHeUS studies enrolled patients newly initiating macitentan, including those with CTD-PAH. This analysis describes patient characteristics, treatment patterns, outcomes, and safety profiles of patients with CTD-PAH newly initiating macitentan in the US using the OPUS/OrPHeUS combined dataset.

Background: Female sex is a significant risk factor for pulmonary arterial hypertension (PAH), yet males with PAH have worse survival - a phenomenon referred to as the "sex paradox" in PAH.

Methods: All adult PAH patients in the Pulmonary Hypertension Association Registry (PHAR) with congruent sex and gender were included. Baseline differences in demographics, hemodynamics, functional parameters, and quality of life were assessed by sex.

Article Synopsis
  • - The study used single-cell and spatial transcriptomics to analyze knee cartilage from 8 osteoarthritis (OA) donors and 3 non-OA controls, revealing a detailed transcriptome and identifying key cell populations involved in OA.
  • - Researchers discovered 11 distinct chondrocyte populations, including 2 novel ones: the pre-inflammatory chondrocyte population (preInfC) and the inflammatory chondrocyte population (InfC), which are crucial for understanding the disease.
  • - The findings suggest that specific chondrocyte populations, like InfC and preHTC, could be targeted for new OA therapies, and profiling these cells may help categorize patients for future clinical trials and personalized treatments.

T-2 toxin and deoxynivalenol (DON) are two prevalent mycotoxins that cause cartilage damage in Kashin-Beck disease (KBD). Cartilage extracellular matrix (ECM) degradation in chondrocytes is a significant pathological feature of KBD. It has been shown that the Hippo pathway is involved in cartilage ECM degradation.

Rationale: Pulmonary hypertension (PH) in COPD confers increased risk of exacerbations (ECOPD). Electrocardiogram (ECG) indicators of PH are prognostic both in PH and COPD. In the Beta-Blockers for the Prevention of Acute Exacerbations of COPD (BLOCK-COPD) trial, metoprolol increased risk of severe ECOPD through unclear mechanisms.

Pulmonary arterial hypertension (PAH) is a heterogeneous disease within a complex diagnostic and treatment environment. Other complex heart and lung diseases have substantial regional variation in characteristics and outcomes; however, this has not been previously described in PAH. To identify baseline differences between U.

Objectives: To investigate discordance in oxy-hemoglobin saturation measured both by pulse oximetry (SpO) and arterial blood gas (ABG, SaO) among critically ill coronavirus disease 2019 (COVID-19(+)) patients compared to COVID-19(-) patients.

Methods: Paired SpO and SaO readings were collected retrospectively from consecutive adult admissions to four critical care units in the United States between March and May 2020. The primary outcome was the rate of discordance (|SaO-SpO|>4%) in COVID-19(+) versus COVID-19(-) patients.

Objective: Despite efforts at early detection, patients with systemic sclerosis (SSc) pulmonary hypertension (PH) present with advanced disease. We sought to determine whether endothelial biomarkers (asymmetric dimethylarginine [ADMA], soluble endoglin [sEng], and pentraxin-3 [PTX-3]) can determine SSc-PH risk or differentiate between SSc-PH subgroups.

Methods: ADMA, sEng, and PTX-3 were measured by enzyme-linked immunosorbent assay in four groups: 1) 18 healthy controls, 2) 74 patients with SSc-PH, 3) 44 patients at high risk for PH features, and 4) 10 patients with low risk for PH features.

This study aimed to investigate the roles of accessible chromatin in understanding the different pathogeneses between Kashin-Beck disease (KBD) and primary osteoarthritis (OA). Articular cartilages of KBD and OA patients were collected, and after tissue digestion, primary chondrocytes were cultured . Assay for transposase-accessible chromatin with high-throughput sequencing (ATAC-seq) was performed to compare the accessible chromatin differences of chondrocytes between KBD and OA groups.

Objective: Pulmonary artery compliance (PAC), estimated as stroke volume (SV) divided by pulmonary artery pulse pressure (PP), may be a predictor of survival in pulmonary arterial hypertension (PAH). Resistance-compliance (RC) time, the product of PAC and pulmonary vascular resistance, is reported to be a physiological constant. We investigated if differences in PAC and RC time exist between pulmonary hypertension (PH) subgroups and examined whether PAC is an independent predictor of transplant-free survival in PAH.

The World Health Organization (WHO) introduced the International Classification of Functioning, Disability, and Health (ICF) as a scientific method of disability data collection comprised of >1,200 categories describing the spectrum of impairment types (functional, symptoms-based and anatomical) under the bio-psycho-social model with consideration of and (pf). ICF Core Sets and ICF Checklists are streamlined disease-specific resources for clinical use, service provision, and for use in health economics and health policy. ICF can disclose strengths and weaknesses across multiple patient-reported outcome measures (PROMs) and help consolidate best-fitting question-items from multiple PROMs.

Nephrogenic systemic fibrosis typically occurs in patients with renal failure and is strongly associated with gadolinium exposure through stimulation of macrophage-activated fibrosis. Patients present with prominent fibrosis of the skin and internal organs. Quality of life is significantly diminished due to impairment from restrictive mobility of large and small joint contractures, pain, and ensuing psychological stress.

Glycoproteins are involved in the development of many diseases, while the type and content of N-glycoproteins in the cartilage of osteoarthritis (OA) and Kashin-Beck disease (KBD) are still unclear. This research aims to identify N-glycoproteins in knee cartilage patients with OA and KBD compared with normal control (N) adults. The cartilage samples were collected from gender- and age-matched OA ( = 9), KBD ( = 9) patients, and N ( = 9) adults.

Objectives: Structured medical records improve readability and ensure the inclusion of information necessary for correct diagnosis and treatment. This is the first study to assess the quality of computer-generated structured medical records by comparing them to conventional medical records on patients with acute abdominal pain.

Materials And Methods: A prospective double-blinded study was conducted in a tertiary referral center emergency department between January 2018 and June 2018.
