Sex-related differences in ventricular remodeling after myocardial infarction.

Int J Cardiol 2021 Jul 24. Epub 2021 Jul 24.

Istituto di Scienze della Vita, Scuola Superiore Sant'Anna, Pisa, Italy; Fondazione Toscana Gabriele Monasterio, Pisa, Italy.

The epidemiology, clinical features and outcome of myocardial infarction (MI) display significant differences between men and women. Prominent sex differences have also been suggested in left ventricular (LV) remodeling after MI. Ventricular remodeling refers to a deterioration of LV geometry and function often leading to heart failure (HF) development and an increased risk of adverse cardiovascular events. Read More

Drusen and pigment abnormality predict the development of neovascular age-related macular degeneration in Japanese patients.

PLoS One 2021 27;16(7):e0255213. Epub 2021 Jul 27.

Department of Ophthalmology, Faculty of Medical Sciences, Kyushu University, Fukuoka, Japan.

Drusen are known to be the important hallmark to predict the development of age-related macular degeneration (AMD). The prevalence of drusen is lower in Asians compared with Caucasians so that the role of signs constituting early AMD is not well established in Asian populations as in Western countries. In this study, we retrospectively investigated clinical characteristics and 5-year incidence of neovascular AMD (nAMD) in the fellow eye of unilateral nAMD patients. Read More

Environ Sci Technol 2021 Jul 27. Epub 2021 Jul 27.

Epidemiology and Environmental Health Joint Research Unit, FISABIO-University Jaume I-University of Valencia, 46019 Valencia, Spain.

Results of studies on perfluoroalkyl substances (PFASs) and thyroid hormones (THs) are heterogeneous, and the mechanisms underlying the action of PFASs to target THs have not been fully characterized. We examined the relation between first-trimester maternal PFAS and TH levels and the role played by polymorphisms in the iodothyronine deiodinase 1 (1) and 2 (2) genes in this association. Our sample comprised 919 pregnant Spanish women (recruitment = 2003-2008) with measurements of perfluorohexanesulfonic acid (PFHxS), perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), perfluorononanoic acid (PFNA), thyroid-stimulating hormone (TSH), total triiodothyronine (TT3), and free thyroxine (FT4), and we genotyped for single-nucleotide polymorphisms in the 1 (rs2235544) and 2 (rs12885300) genes.

Acta Neurol Scand 2021 Jul 27. Epub 2021 Jul 27.

Epilepsy Unit, Department of Human Neurosciences, Policlinico Umberto I, Sapienza University of Rome, Italy.

Objective: Selective sodium channel blockers (SSCBs) have a limited use in genetic generalized epilepsy (GGE), due to their well-known risk of seizure worsening. Although their therapeutic potential in GGE has been suggested by recent evidence, electro-clinical data supporting their prescription are lacking. We aimed to investigate SSCB safety and effectiveness in a GGE cohort. Read More

LINC00667 Promotes Progression of Esophageal Cancer Cells by Regulating miR-200b-3p/SLC2A3 Axis.

Dig Dis Sci 2021 Jul 27. Epub 2021 Jul 27.

Department of Gastroenterology, Taishan Hospital, Taian, Shandong Province, China.

Background: Recently, more and more evidence indicated that the long non-coding RNA was strictly related to the occurrence and progression of human cancers, including esophageal cancer (EC). We observed that LINC00667 was increased in EC, but the function of LINC00667 was unclear. Therefore, the function and potential molecular mechanism of LINC00667 in the progression of EC need to be further studied. Read More

Feasibility of capturing real-world data from health information technology systems at multiple centers to assess cardiac ablation device outcomes: A fit-for-purpose informatics analysis report.

J Am Med Inform Assoc 2021 Jul 27. Epub 2021 Jul 27.

Mercy Research, Mercy, Chesterfield, Missouri, USA.

Objective: The study sought to conduct an informatics analysis on the National Evaluation System for Health Technology Coordinating Center test case of cardiac ablation catheters and to demonstrate the role of informatics approaches in the feasibility assessment of capturing real-world data using unique device identifiers (UDIs) that are fit for purpose for label extensions for 2 cardiac ablation catheters from the electronic health records and other health information technology systems in a multicenter evaluation.

Materials And Methods: We focused on data capture and transformation and data quality maturity model specified in the National Evaluation System for Health Technology Coordinating Center data quality framework. The informatics analysis included 4 elements: the use of UDIs for identifying device exposure data, the use of standardized codes for defining computable phenotypes, the use of natural language processing for capturing unstructured data elements from clinical data systems, and the use of common data models for standardizing data collection and analyses.

Pain Appraisals in Patients with Physical Injury: Assessing the Role of Distress Tolerance in the Relationship between Depression and Pain Catastrophizing.

Health Soc Work 2021 Jul 27. Epub 2021 Jul 27.

Internal Medicine, Epidemiology, University of Utah, Salt Lake City.

Pain is a complex construct contributing to significant impairment, particularly among physically injured patients seeking treatment in trauma and orthopedic surgery settings in which social workers are an integral component of care. The biopsychosocial theory, fear-avoidance, and cognitive mediation models of pain suggest that psychological factors (for example, depression) affect one's ability to tolerate distress, leading to negative pain appraisals, such as catastrophizing. This study examined whether distress tolerance serves as a mechanism by which depression is associated with pain catastrophizing. Read More

Human Papillomavirus-Associated Head and Neck Cancer.

J Am Board Fam Med 2021 Jul-Aug;34(4):832-837

From Division of Otolaryngology-Head and Neck Surgery, George Washington University, Washington, DC (JCN, SF, CM, PEZ).

Oropharyngeal squamous cell carcinoma (OPSCC) has historically been attributable to tobacco and alcohol exposure and saw a decline in incidence after societal norms shifted away from smoking. In recent decades, this disease has had a re-emergence due to human papillomavirus (HPV) infection, now surpassing cervical cancer as the number 1 cause of HPV-related cancer in the United States. HPV-positive OPSCC differs from HPV-negative disease in epidemiology, prognosis, treatment, and prevention. Read More

Monitoring autophagy-dependent ferroptosis.

Methods Cell Biol 2021 18;165:163-176. Epub 2020 Nov 18.

Department of Surgery, University of Texas Southwestern Medical Center, Dallas, TX, United States. Electronic address:

Ferroptosis is an iron-dependent form of regulated cell death, driven by the accumulation of lipid peroxidation. Autophagy is a lysosome-dependent degradation process that can be used to remove and recover intracellular components, such as dysfunctional proteins and damaged organelles. By regulating iron storage and oxidative stress, excessive autophagy is involved in the induction and execution of ferroptosis. Read More

Aryl hydrocarbon receptor activation by Lactobacillus reuteri tryptophan metabolism alleviates Escherichia coli-induced mastitis in mice.

PLoS Pathog 2021 Jul 23;17(7):e1009774. Epub 2021 Jul 23.

Department of Clinical Veterinary Medicine, College of Veterinary Medicine, Jilin University, Changchun, China.

The intestinal microbiota has been associated with the occurrence and development of mastitis, which is one of the most serious diseases of lactating women and female animals, but the underlying mechanism has not yet been elucidated. Aryl hydrocarbon receptor (AhR) activation by microbiota tryptophan metabolism-derived ligands is involved in maintaining host homeostasis and resisting diseases. We investigated whether AhR activation by microbiota-metabolic ligands could influence mastitis development in mice. Read More
