Long-term fasting induces a remodelling of fatty acid composition in erythrocyte membranes.

Introduction: Long-term fasting (LF) activates an adaptative response to switch metabolic fuels from food glucose to lipids stored in adipose tissues. The increase in free fatty acid (FFA) oxidation during fasting triggers health benefits. We questioned if the changes in lipid metabolism during LF could affect lipids in cell membranes in humans.

Physiological basis of non-invasive ventilation in the newborn.

Non-invasive ventilation (NIV) is a form of respiratory support provided primarily to preterm born infants in an effort to avoid any endotracheal intubation or as a weaning step following invasive ventilation. In the context of the respiratory distress syndrome of the newborn, NIV could target and partially reverse specific pathophysiological phenomena, by improving alveolar recruitment and establishing adequate functional residual capacity. It can also assist in minimizing lung injury by avoiding excessive pressure delivery, which can be harmful for the developing lung.

Performance of Noninvasive Tests for Metabolic Dysfunction-Associated Steatohepatitis and Liver Fibrosis Resolution after Bariatric Surgery.

Background: Noninvasive tests (NITs) to monitor metabolic dysfunction-associated steatohepatitis (MASH) progression and response to interventions are needed because of the risks of liver biopsy. A monocytes-based diagnostic test using perilipin-2 (PLIN2) and Ras-related protein-14 (RAB14) predict the severity of MASH and fibrosis. Here we compared the performances of PLIN2 and RAB14 with cytokeratin-18 (CK18) assessed by Ella™ or M65 ELISA in predicting MASH and fibrosis resolution following bariatric surgery in a longitudinal and histologically characterized cohort of individuals with obesity.

Comparative assessment of chondral defect repair using human bone marrow- and adipose tissue-derived mesenchymal stem cells, adult and foetal articular cartilage-derived chondrocytes, and chondroprogenitors: an ex-vivo model.

Purpose: Cartilage repair necessitates adjunct therapies such as cell-based approaches, which commonly use MSCs and chondrocytes but is limited by the formation of fibro-hyaline cartilage. Articular cartilage-derived chondroprogenitors(CPs) offer promise in overcoming this, as they exhibit higher chondrogenic and lower hypertrophic phenotypes. The study aimed to compare the efficacy of various cell types derived from adult and foetal cartilage suspended in platelet-rich plasma(PRP) in repairing chondral defects in an Ex-vivo Osteochondral Unit(OCU) model.

Advantages to interspace-level analyses over person-level analyses when studying relationships between lumbar spinal degeneration findings : a cross-sectional study.

Purpose: To examine associations between lumbar intervertebral disc degeneration (LDD) and type II Modic changes (MC) when retaining information at each interspace ("interspace-level analysis"), as compared to aggregating information across interspaces as is typically done in spine research ("person-level analysis") . The study compared results from (1) interspace-level analyses assuming a common relationship across interspaces (the "interspace-level, common-relationship" approach), (2) interspace-level analyses allowing for interspace-specific associations (an "interspace-level, interspace-specific" approach), and (3) a conventional person-level analytic approach.

Methods: Adults in primary care (n=147) received lumbar spine magnetic resonance imaging (MRI) and neuroradiologist-evaluated assessments of prevalent disc height narrowing (DHN), type II MC, and other LDD parameters.

Long-term efficacy of Mirabegron-anticholinergic combination in paediatric neurogenic bladder.

Introduction: The Mirabegron-anticholinergic (MAC) combination has proven effective as a step-up strategy in managing paediatric neurogenic bladder following anticholinergic medication and botulinum toxin (BTX) therapy. This study assesses the long-term efficacy of MAC in children with neurogenic bladder.

Patients And Methods: A retrospective chart review was conducted from 2015 to 2023, including consecutive paediatric patients receiving Mirabegron (25/50 mg) with an anticholinergic agent (solifenacin 16, tolterodine 7, oxybutynin 7, trospium 1).

Efficacy and safety of low-dose tolvaptan (7.5mg) in the treatment of inpatient hyponatraemia: a retrospective study.

Objectives: The recommended dose of tolvaptan for hyponatraemia secondary to SIADH is 15mg. We evaluated the efficacy of an initial 7.5mg dose and determined the frequency where sodium (Na+) correction exceeded safe limits, defined as an increment of ≥10 mmol/L, within the initial 8 or 24 hours of administration.

Relationship Between Hepatic Iron Concentration and Glycemic Metabolism, Prediabetes, and Type 2 Diabetes: A Systematic Review.

Context: Emerging research has suggested a potential link between high iron levels, indicated by serum ferritin levels, and the development of type 2 diabetes (T2D). However, the role of hepatic iron concentration (HIC) on T2D development and progression is not well understood.

Objectives: This study aims to systematically review the literature on HIC and/or the degree of hepatic iron overload (HIO) in individuals with prediabetes and/or diagnosed T2D, and to analyze associations between HIC and markers of glucose metabolism.

Cardiovascular-Liver-Metabolic Health: Recommendations in Screening, Diagnosis, and Management of Metabolic Dysfunction-Associated Steatotic Liver Disease in Cardiovascular Disease via Modified Delphi Approach.

There is a new awareness of the widespread nature of metabolic dysfunction-associated steatotic liver disease (MASLD) and its connection to cardiovascular disease (CVD). This has catalyzed collaboration between cardiologists, hepatologists, endocrinologists, and the wider multidisciplinary team to address the need for earlier identification of those with MASLD who are at increased risk for CVD. The overlap in the pathophysiologic processes and parallel prevalence of CVD, metabolic syndrome, and MASLD highlight the multisystem consequences of poor cardiovascular-liver-metabolic health.

Novel Diagnostics in Food Allergy.

Food allergy is increasing in prevalence, and poses significant challenges for individuals and their families, adversely impacting their quality of life. Misdiagnosis can lead to unnecessary dietary and social limitations, and increased food allergy risk, while failure to diagnose may result in life-threatening anaphylaxis. Therefore, a precise diagnosis is of the utmost importance; however, barriers exist at every stage of the diagnostic process.

Treatment of food allergy: Immunotherapy, omalizumab, or both.

Food allergy is a common disease which has substantial impacts on the quality of life of patients and their families, and all reactions have the potential for causing life-threatening anaphylaxis. Food allergic individuals currently have 2 FDA approved therapeutic options available to them aside from life-long allergen avoidance: oral immunotherapy (OIT), and omalizumab. OIT for food allergy has been extensively studied in clinical trials and currently provides the greatest level of protection, however it also has a high burden of treatment.

Introduction: The Kidney BEAM randomized controlled trial reported clinically meaningful and statistically significant improvements in mental health-related quality of life (HRQoL), physical function (sit-to-stand-60, but not the physical component of HRQoL) and patient activation after a 12-week physical activity digital health intervention (DHI). This study explores factors that contributed to the effectiveness of Kidney BEAM through mixed methods analyses.

Methods: Quantitative data analysis was obtained from the recently published primary manuscript.

Labor Status at Delivery and Lung Function in Extremely Prematurely Born Young Adults.

Background: There has been conflicting evidence regarding the impact of mode of delivery on respiratory outcomes in later childhood and adulthood. It is possible labor status, rather than mode of delivery, influences later respiratory morbidity. We hypothesized that extremely premature infants born to mothers in labor would have better lung function at follow-up than those born to mothers not in labor.

Relationship between pre-pregnancy body-mass-index and gestational age-specific risk of stillbirth and perinatal death in women with chronic hypertension.
