Effects of Isometric Handgrip Training on Ambulatory Blood Pressure in Individuals Over 18 Years Old: A Systematic Review and Meta-Analysis.

Purpose: The aim of this study was to analyze the effects of isometric handgrip training (IHT) on ambulatory blood pressure (BP) in individuals aged 18 yr and older.

Review Methods: A systematic review and meta-analysis was performed in Medline and Web of Science, encompassing studies published until July 2023, as well as the gray literature. We calculated the mean difference (MD) and 95% CI using an inverse variance method with a random effects model.

S100A9 Drives the Chronification of Psoriasiform Inflammation by Inducing IL-23/Type 3 Immunity.

Psoriasis is a chronic inflammatory skin disorder driven by the IL-23/type 3 immune response. However, molecular mechanisms sustaining the chronicity of inflammation and psoriatic lesions remain elusive. Combining systematic analyses of several transcriptomic datasets, we delineated gene signatures across human psoriatic skin, identifying S100A9 as one of the most up-regulated genes, which was confirmed in lesioned skin from patients with psoriasis and preclinical psoriasiform skin inflammation models.

Sepsis expands a CD39 plasmablast population that promotes immunosuppression via adenosine-mediated inhibition of macrophage antimicrobial activity.

Sepsis results in elevated adenosine in circulation. Extracellular adenosine triggers immunosuppressive signaling via the A2a receptor (A2aR). Sepsis survivors develop persistent immunosuppression with increased risk of recurrent infections.

Linking assessment instruments for brachial plexus injury to the international classification of functioning, disability and health.

Background: Brachial plexus injuries (BPI) affect not only body structure and function, but also several aspects of individual's well-being. Considering the crescent need for assessing such patients through a biopsychosocial perspective, linking meaningful concepts of BPI instruments to the International Classification of Functioning, Disability and Health (ICF) provides a useful overview of how the ICF components are contemplated on the current measurements available.

Purpose: To identify patient-reported outcome measures (PROMs) specifically designed for BPI assessment and link the content with the ICF.

Barriers to physical activity during the COVID-19 pandemic in adults: a cross-sectional study.

Social isolation due to the coronavirus disease 2019 (COVID-19) pandemic has reduced physical activity levels in both men and women. The identification of barriers to physical activity may assist in developing strategies to increase levels of physical activity during this pandemic. The study aim was identify the barriers to regular participation in physical during the COVID-19 pandemic in Brazilian adults.

NLRP12 controls arthritis severity by acting as a checkpoint inhibitor of Th17 cell differentiation.

Nucleotide oligomerization domain (NOD)-like receptor-12 (NLRP12) has emerged as a negative regulator of inflammation. It is well described that the Th17 cell population increases in patients with early Rheumatoid Arthritis (RA), which correlates with the disease activity. Here, we investigated the role of NLRP12 in the differentiation of Th17 cells and the development of experimental arthritis, using the antigen-induced arthritis (AIA) murine model.

Galectin-3 aggravates experimental polymicrobial sepsis by impairing neutrophil recruitment to the infectious focus.

Sepsis is an overwhelming systemic inflammation resulting from an uncontrolled infection that causes extensive tissue damage, organ dysfunction and eventually death. A growing body of evidence indicates that impaired neutrophil migration to the site of infection is associated with poor outcome in sepsis. Here we show that galectin-3 (Gal-3), an endogenous glycan-binding protein, plays a critical role in sepsis outcome.

The Atypical Chemokine Receptor ACKR2 is Protective Against Sepsis.

Sepsis is a systemic inflammatory response as a result of uncontrolled infections. Neutrophils are the first cells to reach the primary sites of infection, and chemokines play a key role in recruiting neutrophils. However, in sepsis chemokines could also contribute to neutrophil infiltration to vital organs leading to multiple organ failure.

IL-33 contributes to sepsis-induced long-term immunosuppression by expanding the regulatory T cell population.

Patients who survive sepsis can develop long-term immune dysfunction, with expansion of the regulatory T (Treg) cell population. However, how Treg cells proliferate in these patients is not clear. Here we show that IL-33 has a major function in the induction of this immunosuppression.

Neutrophil Extracellular Traps Induce Organ Damage during Experimental and Clinical Sepsis.

Organ dysfunction is a major concern in sepsis pathophysiology and contributes to its high mortality rate. Neutrophil extracellular traps (NETs) have been implicated in endothelial damage and take part in the pathogenesis of organ dysfunction in several conditions. NETs also have an important role in counteracting invading microorganisms during infection.

Post-Sepsis State Induces Tumor-Associated Macrophage Accumulation through CXCR4/CXCL12 and Favors Tumor Progression in Mice.

Survivors from sepsis are in an immunosuppressed state that is associated with higher long-term mortality and risk of opportunistic infections. Whether these factors contribute to neoplastic proliferation, however, remains unclear. Tumor-associated macrophages (TAM) can support malignant cell proliferation, survival, and angiogenesis.

Target Inhibition of IL-1 Receptor Prevents Ifosfamide Induced Hemorrhagic Cystitis in Mice.

Purpose: Hemorrhagic cystitis is an important dose limiting side effect of ifosfamide based cancer chemotherapy. Despite chemoprophylaxis inflammation can still be found in cystoscopy guided biopsies. Previous studies confirmed the role of TNF-α and IL-1β.
