Patient factors related to patient engagement technology (PET) usage in thoracic surgery.

Background: We evaluated using Patient Engagement Technology (PET) to capture Patient Reported Outcomes (PROs) in thoracic surgery patients. METHODSY: atients using a PET received surveys including the Patient-Reported Outcomes Measurement Information System Global-10 (PROMIS-10) and a health literacy (HL) screen. The relationship of patient-level factors with survey completion was assessed through univariate and logistic regression analyses.

Myeloid Heterogeneity Mediates Acute Exacerbations of Pulmonary Fibrosis.

Epidemiological evidence indicates that exposure to particulate matter is linked to the development of idiopathic pulmonary fibrosis (IPF) and increases the incidence of acute exacerbations of IPF. In addition to accelerating the rate of lung function decline, exposure to fine particulate matter (particulate matter smaller than 2.5 μm [PM2.

Sublobar Resections: Indications and Approaches.

Sublobar resections are commonly performed operations that have seen an increase in applicability. The sublobar approach, comprising segmentectomy and wedge resections, can provide lung preservation and thus is better tolerated in select patients in comparison to lobectomy. These operations are offered for a variety of benign and malignant lesions.

Impaired PPARγ activation by cadmium exacerbates infection-induced lung injury.

Emerging data indicate an association between environmental heavy metal exposure and lung disease, including lower respiratory tract infections (LRTIs). Here, we show by single-cell RNA sequencing an increase in Pparg gene expression in lung macrophages from mice exposed to cadmium and/or infected with Streptococcus pneumoniae. However, the heavy metal cadmium or infection mediated an inhibitory posttranslational modification of peroxisome proliferator-activated receptor γ (PPARγ) to exacerbate LRTIs.

Mitochondrial fission and bioenergetics mediate human lung fibroblast durotaxis.

Pulmonary fibrosis is characterized by stiffening of the extracellular matrix. Fibroblasts migrate in the direction of greater stiffness, a phenomenon termed durotaxis. The mechanically guided fibroblast migration could be a crucial step in the progression of lung fibrosis.

Role of hair follicles in the pathogenesis of arsenical-induced cutaneous damage.

Arsenical vesicants cause skin inflammation, blistering, and pain. The lack of appropriate animal models causes difficulty in defining their molecular pathogenesis. Here, Ptch1 /C57BL/6 mice were employed to investigate the pathobiology of the arsenicals lewisite and phenylarsine oxide (PAO).

Assessment of Testamentary Capacity in Older Adults: Description and Initial Validation of a Standardized Interview Instrument.

Objective: Testamentary capacity (TC) is a legal construct, which concerns a person's mental capacity to make or amend a will. Although expert clinicians are frequently asked to assess TC in forensic settings, there are few instruments and little empirical research to inform and guide their assessments. The present study describes the development and psychometric properties of a standardized assessment measure of TC (Testamentary Capacity Instrument-TCI), and investigates its reliability and validity.

Bacterial Sexually Transmitted Infection Incidence Among Southern Men Who Have Sex With Men With Human Immunodeficiency Virus in the Treatment as Prevention Era, 2014-2019.

In this retrospective analysis of men who have sex with men with human immunodeficiency virus (HIV) in the South from 2014 through 2019, incident bacterial sexually transmitted infections (STIs) increased regardless of virologic control. Clinicians should prioritize STI screening and management in primary HIV care.

Dynamic Regulation of the Nexus Between Stress Granules, Roquin, and Regnase-1 Underlies the Molecular Pathogenesis of Warfare Vesicants.

The use of chemical warfare agents is prohibited but they have been used in recent Middle Eastern conflicts. Their accidental exposure (e.g.

Expanded renal lymphatics improve recovery following kidney injury.

Acute kidney injury (AKI) is a major cause of patient mortality and a major risk multiplier for the progression to chronic kidney disease (CKD). The mechanism of the AKI to CKD transition is complex but is likely mediated by the extent and length of the inflammatory response following the initial injury. Lymphatic vessels help to maintain tissue homeostasis through fluid, macromolecule, and immune modulation.

VEGFR3 tyrosine kinase inhibition aggravates cisplatin nephrotoxicity.

Expansion of renal lymphatic networks, or lymphangiogenesis (LA), is well recognized during development and is now being implicated in kidney diseases. Although LA is associated with multiple pathological conditions, very little is known about its role in acute kidney injury. The purpose of this study was to evaluate the role of LA in a model of cisplatin-induced nephrotoxicity.

The molecular evolution of function in the CFTR chloride channel.

The ATP-binding cassette (ABC) transporter superfamily includes many proteins of clinical relevance, with genes expressed in all domains of life. Although most members use the energy of ATP binding and hydrolysis to accomplish the active import or export of various substrates across membranes, the cystic fibrosis transmembrane conductance regulator (CFTR) is the only known animal ABC transporter that functions primarily as an ion channel. Defects in CFTR, which is closely related to ABCC subfamily members that bear function as bona fide transporters, underlie the lethal genetic disease cystic fibrosis.

ReHouSED: A novel measurement of Veteran housing stability using natural language processing.

Housing stability is an important determinant of health. The US Department of Veterans Affairs (VA) administers several programs to assist Veterans experiencing unstable housing. Measuring long-term housing stability of Veterans who receive assistance from VA is difficult due to a lack of standardized structured documentation in the Electronic Health Record (EHR).

The BET Inhibitor JQ1 Augments the Antitumor Efficacy of Gemcitabine in Preclinical Models of Pancreatic Cancer.

Gemcitabine is used to treat pancreatic cancer (PC), but is not curative. We sought to determine whether gemcitabine + a BET bromodomain inhibitor was superior to gemcitabine, and identify proteins that may contribute to the efficacy of this combination. This study was based on observations that cell cycle dysregulation and DNA damage augment the efficacy of gemcitabine.

HIV and COVID-19: Lessons From HIV and STI Harm Reduction Strategies.

Purpose Of Review: This review highlights the intersection of the COVID-19, HIV, and STI pandemics and examines how harm reduction strategies can be applied broadly to controlling a pandemic.

Recent Findings: Since the onset of the COVID-19 pandemic, remarkable advances in the understanding of COVID-19 prevention, diagnosis, and treatment have been made at a much faster pace than prior pandemics, yet much more still remains to be discovered. Many of the strategies to control the COVID-19 pandemic mirror those employed to stem the HIV pandemic.

Post-translational regulation of PGC-1α modulates fibrotic repair.

Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease associated with mitochondrial oxidative stress. Mitochondrial reactive oxygen species (mtROS) are important for cell homeostasis by regulating mitochondrial dynamics. Here, we show that IPF BAL cells exhibited increased mitochondrial biogenesis that is, in part, due to increased nuclear expression of peroxisome proliferator-activated receptor-ɣ (PPARɣ) coactivator (PGC)-1α.

NOX4 regulates macrophage apoptosis resistance to induce fibrotic progression.

Pulmonary fibrosis is a progressive lung disease often occurring secondary to environmental exposure. Asbestos exposure is an important environmental mediator of lung fibrosis and remains a significant cause of disease despite strict regulations to limit exposure. Lung macrophages play an integral role in the pathogenesis of fibrosis induced by asbestos (asbestosis), in part by generating reactive oxygen species (ROS) and promoting resistance to apoptosis.

Expression of lactate dehydrogenase A and B isoforms in the mouse kidney.

Cellular metabolic rates in the kidney are critical for maintaining normal renal function. In a hypoxic milieu, cells rely on glycolysis to meet energy needs, resulting in the generation of pyruvate and NADH. In the absence of oxidative phosphorylation, the continuation of glycolysis is dependent on the regeneration of NAD from NADH accompanied by the fermentation of pyruvate to lactate.

New insights into the role of heme oxygenase-1 in acute kidney injury.

Acute kidney injury (AKI) is attended by injury-related biomarkers appearing in the urine and serum, decreased urine output, and impaired glomerular filtration rate. AKI causes increased morbidity and mortality and can progress to chronic kidney disease and end-stage kidney failure. AKI is without specific therapies and is managed by supported care.

Current State and Future of Research in Nephrology.

The focus of this article is to review the available funding opportunities for the nephrology workforce at all career levels and review the current challenges involved in the career of a physician-scientist. While the scarcity of nephrology fellows for training programs is a continuing challenge, increased funding for the National Institutes of Health is encouraging particularly for early career investigators. In addition to National Institutes of Health funding, other funding sources are also discussed as they provide much needed bridge funding during key transition periods for young careers.
