Association Between Visceral Fat and Lung Function Impairment in Overweight and Grade I Obese Women: A Cross-Sectional Study.

Adv Respir Med

December 2024

Laboratory of Pulmonary and Exercise Immunology (LABPEI), Evangelical University of Goiás (UniEvangélica), Avenida Universitária Km 3,5, Anápolis 75083-515, GO, Brazil.

Beyond the common comorbidities related to obesity, such as type 2 diabetes and cardiovascular diseases, impaired lung function is already known, but whether the fat distribution (sub-cutaneous, visceral) affects the lung function and pulmonary immune response are poorly known. Few evidence has shown that visceral fat is associated with insulin resistance, low-grade inflammation, and reduced lung function. In the present study, the body composition and fat distribution were evaluated by multi-frequency octopolar bioimpedance.

T cells are involved in protective immunity against numerous viral infections. Data regarding functional roles of human T cells in SARS-CoV-2 (SARS2) viral clearance in primary COVID-19 are limited. To address this knowledge gap, we assessed samples for associations between SARS2 upper respiratory tract viral RNA levels and early virus-specific adaptive immune responses for 95 unvaccinated clinical trial participants with acute primary COVID-19 aged 18-86 years old, approximately half of whom were considered at high risk for progression to severe COVID-19.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) are resistant to nearly all β-lactam antibiotics under standard testing conditions. However, a novel phenotype exists wherein certain MRSA strains exhibit β-lactam susceptibility in the presence of bicarbonate (termed 'NaHCO3-responsive'), an abundant ion in mammalian tissues and blood. This suggests that specific MRSA infections may be treatable by β-lactams.

Purpose Of Review: Inflammation has been commonly known for the past decade as a part of the pathophysiology of atherosclerosis, along with lipid accumulation. However, some patients with optimized lipid-lowering therapy still have elevated inflammatory biomarkers. Anti-inflammation therapies were developed to eradicate this residual risk.

Background: CD20-targeted therapies are widely used in the management of B-cell lymphomas. Re-treatment with CD20-directed agents is common; however, previous research has demonstrated loss of CD20 expression at relapse in a subset of patients.

Methods: In this single-center retrospective cohort of 243 patients, CD20 analysis was performed by immunohistochemistry (IHC) and/or flow cytometry at diagnosis and at relapse if a biopsy was performed.

May-Thurner syndrome, also known as external iliac compression syndrome, is a rare but commonly underdiagnosed cause of asymmetric lower extremity edema. Here we describe a case of May-Thurner syndrome owing to external compression of the right and left common iliac veins presenting as chronic worsening asymmetric right greater than left lower extremity edema. Initial etiology workup was unremarkable, and further diagnostics revealed compression of the right common iliac vein at the bifurcation of the right common iliac artery between the right external and internal iliac arteries with concomitant compression of the left common iliac vein.

Objective: To investigate hippocampal volume changes in moderate to severe traumatic brain injury (TBI) patients compared to healthy controls and assess their association with post-traumatic epilepsy (PTE), focusing on age-related effects.

Methods: Imaging and demographic data for TBI patients were obtained from the Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx) database; healthy controls matched by age and sex were sourced from Alzheimer's Disease Neuroimaging Initiative (ADNI), the National Institute of Mental Health (NIMH) Intramural Healthy Volunteer Dataset, the Parkinson's Progression Markers Initiative (PPMI), and the Autism Brain Imaging Data Exchange (ABIDE). MRI images for TBI subjects were obtained within 14-32 days post-injury.

Mucormycosis is an emerging, life-threatening human infection caused by fungi of the order Mucorales. Metabolic disorders uniquely predispose an ever-expanding group of patients to mucormycosis via poorly understood mechanisms. Therefore, it is highly likely that uncharacterized host metabolic effectors confer protective immunity against mucormycosis.

Background: Allostatic load index (ALI) is often utilized to quantify the physiological response to stress. This study assesses the relationship between ALI and its impact on all-cause, cardiovascular, and stroke mortality in individuals with a self-reported history of stroke and within the general National Health and Nutritional Examination Survey sampled population.

Methods: Using data from the National Health and Nutritional Examination Survey (III, 1988-1994) and the 2015 Linked Mortality File, we selected adults aged ≥25 years with self-reported stroke.

The Clinical Practice Standards Committee of the American Association for Thoracic Surgery assembled an expert panel and conducted a systematic review of the literature detailing studies directly comparing treatment options for high-risk patients with stage I non-small cell lung cancer (NSCLC). A systematic search was performed to identify publications comparing outcomes following image-guided thermal ablation (IGTA), stereotactic ablative radiotherapy (SABR), and sublobar resection-the main treatment options applicable to high-risk patients with stage I NSCLC. There were no publications detailing completed randomized controlled trials comparing these treatment options.

Department of Cardiothoracic Surgery, University of Pittsburgh School of Medicine, University of Pittsburgh Medical Center, and UPMC Hillman Cancer Center. Pittsburgh, PA. Electronic address:

Stereotactic ablative radiotherapy (SABR) has emerged as an alternative, non-surgical treatment for high-risk patients with stage I non-small cell lung cancer (NSCLC) with increased use over time. The American Association for Thoracic Surgery (AATS) Clinical Practice Standards Committee (CPSC) assembled an expert panel and conducted a systematic review of the literature evaluating the results of SABR, which is also referred to as stereotactic body radiation therapy (SBRT) or stereotactic radiosurgery (SRS), prior to developing treatment recommendations for high-risk patients with stage I NSCLC based on expert consensus. Publications detailing the findings of 16 prospective studies of SABR and 14 retrospective studies of SABR for the management of early-stage lung cancer in 54 697 patients were identified by systematic review of the literature with further review by members of our expert panel.

Sublobar resection offers a parenchymal-sparing surgical alternative to lobectomy and includes wedge resection and segmentectomy. Sublobar resection has been historically utilized in high-risk patients with compromised lung function; however, the technique is becoming more prevalent for normal-risk patients with peripheral lung tumors < 2 cm. In this article, we summarize the technique of sublobar resection, the importance of surgical margins and lymph node sampling, patient selection, perioperative complications, outcomes, and the impact of sublobar resection on the quality of life.

Article Synopsis
  • * An expert panel from the American Association for Thoracic Surgery reviewed existing literature and reached a consensus on treatment modalities, which include sublobar resection, image-guided thermal ablation (IGTA), and stereotactic ablative radiotherapy (SABR).
  • * The conclusions highlight that surgical approaches are often preferred when safe, but SABR and IGTA can be suitable alternatives; multidisciplinary evaluations and patient preferences play crucial roles in treatment decisions.
