Expression of ABCB1, ABCC1, and LRP in Mesenchymal Stem Cells from Human Amniotic Fluid and Bone Marrow in Culture-Effects of In Vitro Osteogenic and Adipogenic Differentiation.

Int J Mol Sci

Lipids, Oxidation, and Cell Biology Group, Laboratory of Immunology (LIM19), Heart Institute (InCor), Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo (HCFMUSP), São Paulo 05403-900, Brazil.

Mesenchymal stem cells (MSCs) are multipotent cells with the potential to differentiate into various lineages. They have also the potential to protect themselves against harmful stimuli to maintain their functional integrity. Drug resistance-related transporters such as ABCB1 (P-glycoprotein; P-gp), ABCC1 (MRP1; multidrug resistance-related Protein 1), and LRP (lung resistance protein) may protect MSCs against toxic substances such as chemotherapeutic agents.

Eur Heart J

January 2025

Department of Primary Care and Public Health, Imperial Centre for Cardiovascular Disease Prevention, School of Public Health, Imperial College London, White City Campus, 90 Wood Lane, London W12 0BZ, UK.

Background And Aims: Overweight and obesity are modifiable risk factors for atherosclerotic cardiovascular disease (ASCVD) in the general population, but their prevalence in individuals with heterozygous familial hypercholesterolaemia (HeFH) and whether they confer additional risk of ASCVD independent of LDL cholesterol (LDL-C) remains unclear.

Methods: Cross-sectional analysis was conducted in 35 540 patients with HeFH across 50 countries, in the EAS FH Studies Collaboration registry. Prevalence of World Health Organization-defined body mass index categories was investigated in adults (n = 29 265) and children/adolescents (n = 6275); and their association with prevalent ASCVD.

Cachexia is a multifactorial metabolic syndrome characterized by weight and skeletal muscle loss caused by underlying illnesses such as cancer, heart failure, and renal failure. Inflammation, insulin resistance, increased muscle protein degradation, decreased food intake, and anorexia are the primary pathophysiological drivers of cachexia. Cachexia causes physical deterioration and functional impairment, loss of quality of life, lower response to active treatment, and ultimately morbidity and mortality, while the difficulties in tackling cachexia in its advanced phases and the heterogeneity of the syndrome among patients require an individualized and multidisciplinary approach from an early stage.

Advanced heart failure primarily manifests during and after hospitalization for decompensation. Identifying prognostic factors is crucial for distinguishing patients who may benefit from drug therapy from those with end-stage disease. This study aimed to evaluate the prognostic significance of systemic vasoconstriction in patients with decompensated heart failure with a reduced ejection fraction.

The COVID-19 pandemic has prompted a quest to understand why certain individuals remain uninfected or asymptomatic despite repetitive exposure to SARS-CoV-2. Here, we focused on six exposed females residing with their symptomatic and reinfected SARS-CoV-2 PCR-positive COVID-19 partners. Peripheral blood mononuclear cell samples from couples were analysed for poly (I:C)-induced mRNA expression of type I/III interferons and interferon-stimulated genes (ISGs).

Acute decompensated pulmonary hypertension outcomes in pulmonary arterial hypertension patients: systematic review and meta-analysis of proportions.

Heart Lung

November 2024

Intensive Care Unit, AC Camargo Cancer Center, São Paulo, Brazil; Pulmonary Department, Heart Institute (InCor), Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo, São Paulo, Brazil.

Article Synopsis
  • Acute decompensated pulmonary arterial hypertension (ADPH) leads to right heart failure, posing a high risk of mortality, making the assessment of mortality rates and life-sustaining therapies essential for patient management.
  • A systematic review of 25 studies showed ICU mortality at 29% and hospital mortality at 38%, with higher mortality (45%) among patients needing extracorporeal membrane oxygenation (ECMO). Additional treatments like inotropes and vasopressors also indicated increased mortality rates.
  • The study highlights the variability in ADPH mortality related to different clinical settings and therapies, emphasizing the importance of these findings for clinical practice and discussions with patients and their families.

D-PRISM: a global survey-based study to assess diagnostic and treatment approaches in pneumonia managed in intensive care.

Crit Care

November 2024

Division of Perioperative, Acute, Critical Care and Emergency Medicine, Department of Medicine, University of Cambridge, Level 4, Addenbrooke's Hospital, Hills Road, Cambridge, UK.

Article Synopsis
  • The D-PRISM study investigated global practices for diagnosing and treating pneumonia in ICU settings, focusing on community-acquired, hospital-acquired, and ventilator-associated pneumonia across different countries.
  • A survey gathered responses from 1,296 ICU clinicians across 72 countries, revealing varied diagnostic processes and a lack of standardized microbiological testing, particularly in lower-income regions.
  • Findings indicated that the typical antibiotic treatment duration was 5-7 days, with shorter durations linked to effective antimicrobial stewardship programs in higher-income countries.

Drugs for dyslipidaemia: the legacy effect of the Scandinavian Simvastatin Survival Study (4S).

Lancet

December 2024

School of Medicine, University of Western Australia, Perth, WA, Australia; Cardiometabolic Service, Department of Cardiology and Internal Medicine, Royal Perth Hospital, Perth, WA, Australia.

Since the discovery of statins and the Scandinavian Simvastatin Survival Study (4S) results three decades ago, remarkable advances have been made in the treatment of dyslipidaemia, a major risk factor for atherosclerotic cardiovascular disease. Safe and effective statins remain the cornerstone of therapeutic approach for this indication, including for children with genetic dyslipidaemia, and are one of the most widely prescribed drugs in the world. However, despite the affordability of generic statins, they remain underutilised worldwide.

Senescent cell depletion alleviates obesity-related metabolic and cardiac disorders.

Mol Metab

January 2025

Department of Anatomy, Institute of Biomedical Sciences, University of Sao Paulo, Sao Paulo, SP, Brazil; Center for Regenerative Medicine, USF Health Heart Institute, University of South Florida, Tampa, FL, USA. Electronic address:

Unlabelled: Obesity is a major contributor to metabolic and cardiovascular disease. Although senescent cells have been shown to accumulate in adipose tissue, the role of senescence in obesity-induced metabolic disorders and in cardiac dysfunction is not yet clear; therefore, the therapeutic potential of managing senescence in obesity-related metabolic and cardiac disorders remains to be fully defined.

Objective: We investigated the beneficial effects of a senolytic cocktail (dasatinib and quercetin) on senescence and its influence on obesity-related parameters.

Objective: To evaluate the possible reversibility of PAH to a normopressoric state in SLE after induction immunosuppressive (IS) and predictors of response.

Methods: We retrospectively evaluated all SLE-PAH patients who underwent IS therapy at our center. PAH reversion was defined as the normalization of pulmonary arterial pressure (PAP), either by the presence of systolic PAP <40 mmHg on echocardiogram or mean PAP <20 mmHg on right heart catheterization (RHC).
