Rest-Activity Rhythm Fragmentation and Weaker Circadian Strength Are Associated With Cognitive Impairment in Survivors of Acute Respiratory Failure.

Biol Res Nurs 2022 Jun 27:10998004221109925. Epub 2022 Jun 27.

Division of Pulmonary, Critical Care and Sleep Medicine, 205280University of Washington, Seattle, WA, USA.

: Survivors of acute respiratory failure (ARF) experience long-term cognitive impairment and circadian rhythm disturbance after hospital discharge. Although prior studies in aging and neurodegenerative diseases indicate actigraphy-estimated rest-activity circadian rhythm disturbances are risk factors for cognitive impairment, it is unclear if this applies to ARF survivors. This study explored the relationships of actigraphy-estimated rest-activity circadian rhythms with cognitive functioning in ARF survivors at 3 months after discharge. Read More

Transpl Int 2022 9;35:10546. Epub 2022 Jun 9.

Department of Medical Sciences, University of Turin, Turin, Italy.

Despite advances in immunosuppression therapy, acute rejection remains the leading cause of graft dysfunction in lung transplant recipients. Donor-derived cell-free DNA is increasingly being considered as a valuable biomarker of acute rejection in several solid organ transplants. We present a technically improved molecular method based on digital PCR that targets the mismatch between the recipient and donor at the locus. Read More

Quantitative Computed Tomography: What Clinical Questions Can it Answer in Chronic Lung Disease?

Lung 2022 Jun 25. Epub 2022 Jun 25.

Department of Radiology, University of Florida, Gainesville, FL, USA.

Quantitative computed tomography (QCT) has recently gained an important role in the functional assessment of chronic lung disease. Its capacity in diagnostic, staging, and prognostic evaluation in this setting is similar to that of traditional pulmonary function testing. Furthermore, it can demonstrate lung injury before the alteration of pulmonary function test parameters, and it enables the classification of disease phenotypes, contributing to the customization of therapy and performance of comparative studies without the intra- and inter-observer variation that occurs with qualitative analysis.

Mannose-Binding Lectin (MBL) and Gap Junction Protein Alpha 4 (GJA4) Gene Heterogeneity in Relation to Severity of Clinical Disease in Cystic Fibrosis.

Front Biosci (Landmark Ed) 2022 May;27(6):168

University Children's Hospital Bonn, 53127 Bonn, Germany.

Background: Recently, we provided evidence that a single nucleotide polymorphism (SNP), rs41266431, on the gap junction protein alpha 4 (GJA4) gene, acts as a modifier for clinical disease severity in patients with cystic fibrosis (CF). These features are very similar to those of variants of the mannose-binding lectin (MBL). This study aimed to clarify whether the clinical disease phenotype associated with GJA4 variants is independent of MBL variants. Read More

Value of the Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio in Predicting CPET Performance in Patients with Stable CAD and Recent Elective PCI.

Medicina (Kaunas) 2022 Jun 16;58(6). Epub 2022 Jun 16.

Medical I Department, Faculty of Medicine, "Grigore T. Popa" University of Medicine and Pharmacy, 700115 Iasi, Romania.

: Functional capacity (FC) assessed via cardiopulmonary exercise testing (CPET) is a novel, independent prognostic marker for patients with coronary artery disease (CAD). Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are two readily available predictors of systemic inflammation and cardiovascular event risk, which could be used as cost-effective predictors of poor FC. The purpose of this study was to evaluate the utility of NLR and PLR in predicting poor FC in patients with CAD and recent elective percutaneous coronary intervention (PCI). Read More

Int J Environ Res Public Health 2022 Jun 19;19(12). Epub 2022 Jun 19.

Center for Liberal Arts, Fukuoka Institute of Technology, Fukuoka 811-0295, Japan.

This study aimed to compare the degree of exhaustion and trophic effects between continuous exercise (CE) and intermittent exercise (IE) at lactate threshold (LT) intensity. Seven healthy men (age: 43-69 years) performed the following three experimental tests in a randomized crossover order: (1) control; (2) CE, performed as a 20-min of cycling at LT intensity; and (3) IE, performed as 20 sets of a one-min bout of cycling at LT intensity with a 30-s rest between every two sets. Heart rate (HR), blood lactate concentration (LA), rating of perceived exertion (RPE), catecholamines, cortisol, growth hormone, insulin-like growth factor (IGF)-1, and brain-derived neurotrophic factor (BDNF) were measured.

Switching to a Standard Chow Diet at Weaning Improves the Effects of Maternal and Postnatal High-Fat and High-Sucrose Diet on Cardiometabolic Health in Adult Male Mouse Offspring.

Metabolites 2022 Jun 18;12(6). Epub 2022 Jun 18.

Department of Kinesiology, University of Texas at San Antonio, San Antonio, TX 78249, USA.

Cardiac mitochondrial dysfunction contributes to obesity-associated heart disease. Maternal and postnatal diet plays an important role in cardiac function, yet the impacts of a mismatch between prenatal and postweaning diet on cardiometabolic function are not well understood. We tested the hypothesis that switching to a standard chow diet after weaning would attenuate systemic metabolic disorders and cardiac and mitochondrial dysfunction associated with maternal and postnatal high-fat/high-sucrose (HFHS) diet in mice.
