Sarcoidosis Treatment Patterns in the United States: 2016-2022.

Background: There are limited US Federal Drug Administration-approved medications and real-world data on sarcoidosis treatment in the United States. Concordance of practice patterns with guideline recommendations have not been well characterized.

Research Question: What are the practice patterns and factors associated with treatment for patients with sarcoidosis in the year following diagnosis?

Study Design And Methods: A retrospective analysis was conducted of patients with sarcoidosis from 2016 to 2022 using a multicenter, all-payer claims database (TriNetX).

Integrative epidemiology and immunotranscriptomics uncover a risk and potential mechanism for cutaneous lymphoma unmasking or progression with dupilumab therapy.

Background: There have been multiple reports of the anti-IL-4Rα agent, dupilumab, being associated with the onset and/or progression of cutaneous T-cell lymphoma (CTCL).

Objective: We sought to evaluate safety signals associated with dupilumab, with a focus on CTCL, and to evaluate the possible underlying mechanism or mechanisms for the potential association.

Methods: First, we used the Food and Drug Administration's pharmacovigilance database, FAERS (FDA Adverse Event Reporting System), to evaluate whether dupilumab was associated with CTCL, including both positive outcome controls (conjunctivitis, eosinophilia, and arthralgia) and exposure controls (other medications with similar indications, including JAK inhibitors and the anti-IL-13 agent, tralokinumab) to evaluate confounding bias.

Impaired insulin signaling and diet-induced type 3 diabetes pathophysiology increase amyloid β expression in the Drosophila model of Alzheimer's disease.

Compelling evidence has strongly linked unregulated sugar levels to developing Alzheimer's disease, suggesting Alzheimer's to be 'diabetes of the brain or 'type 3 diabetes. Insulin resistance contributes to the pathogenesis of Alzheimer's disease due to uncontrolled and unchecked blood glucose, though the interrelatedness between Alzheimer's disease and type 2 diabetes is debatable. Here we describe the consequences of inducing type 3 diabetes by feeding Drosophila on a high sucrose diet, which effectively mimics the pathophysiology of diabetes.

Investigating the differential structural organization and gene expression regulatory networks of lamin A Ig fold domain mutants of muscular dystrophy.

Lamins form a proteinaceous meshwork as a major structural component of the nucleus. Lamins, along with their interactors, act as determinants for chromatin organization throughout the nucleus. The major dominant missense mutations responsible for autosomal dominant forms of muscular dystrophies reside in the Ig fold domain of lamin A.

A thorough literature review was conducted on the MEDLINE database to synthesize current knowledge and propose future research directions.

A case of rapidly progressive unilateral non-nephrogenic hemorrhagic bullous calciphylaxis responding to systemic sodium thiosulfate therapy.

Background: Calciphylaxis is a rare and life-threatening condition characterized by cutaneous necrosis resulting from vessel calcification and thrombosis. Commonly associated with end-stage renal disease and hyperparathyroidism, calciphylaxis presents as retiform purpura evolving into necrotic eschars.

Case Report: This report details an atypical case of non-nephrogenic unilateral bullous calciphylaxis in a 71-year-old female, emphasizing the importance of considering calciphylaxis in the differential diagnosis of bullous disorders.

Rheumatoid arthritis associated recurrent pleural effusion.

Pleural effusions and pulmonary nodules are known complications of rheumatoid arthritis (RA) though pleural extra-articular manifestations without clinical arthritis are rare. We present a 66-year-old male with dyspnea and weight loss, whose imaging revealed pleural effusions and lung nodules, multiple exudative pleural effusions, and a thoracoscopic biopsy showing chronic pleuritis and granulomatous inflammation. Subsequent joint stiffness and positive rheumatoid markers led to a RA diagnosis.

A mixed-methods survey and focus group study to understand researcher and clinician preferences for a Journal transparency Tool.

Transparency within biomedical research is essential for research integrity, credibility, and reproducibility. To increase adherence to optimal scientific practices and enhance transparency, we propose the creation of a journal transparency tool (JTT) that will allow users to obtain information about a given scholarly journal's operations and transparency policies. This study is part of a program of research to obtain user preferences to inform the proposed JTT.

Food Insecurity Among LGBQ+ Veterans.

Importance: Food insecurity is associated with numerous adverse health outcomes. Little is known about the prevalence of and risks for food insecurity among veterans identifying as lesbian, gay, bisexual, queer, and similar (LGBQ+), a population facing unique social barriers and medical comorbidities.

Objective: To examine food insecurity and potential risk factors among LGBQ+ veterans.

Caspases promote cell proliferation after necrosis.

An enzyme known as caspase, which initiates apoptosis, has a central role in the regeneration of cells and repair of tissue that can occur after necrosis.

Integrating Big Data, Artificial Intelligence, and motion analysis for emerging precision medicine applications in Parkinson's Disease.

One of the key challenges in Big Data for clinical research and healthcare is how to integrate new sources of data, whose relation to disease processes are often not well understood, with multiple classical clinical measurements that have been used by clinicians for years to describe disease processes and interpret therapeutic outcomes. Without such integration, even the most promising data from emerging technologies may have limited, if any, clinical utility. This paper presents an approach to address this challenge, illustrated through an example in Parkinson's Disease (PD) management.

ACR Appropriateness Criteria® Nonvariceal Upper Gastrointestinal Bleeding: 2024 Update.

This document summarizes the relevant literature for the selection of the initial imaging in five clinical scenarios in patients with suspected or known nonvariceal upper gastrointestinal bleeding (UGIB). These clinical scenarios include suspected nonvariceal UGIB without endoscopy performed; endoscopically confirmed nonvariceal UGIB with clear source but treatment not possible or continued bleeding after endoscopic treatment; endoscopically confirmed nonvariceal UGIB without a confirmed source; suspected nonvariceal UGIB with negative endoscopy; and postsurgical or post-traumatic nonvariceal UGIB when endoscopy is contraindicated. The appropriateness of imaging modalities as they apply to each clinical scenario is rated as usually appropriate, may be appropriate, and usually not appropriate to assist the selection of the most appropriate imaging modality in the corresponding clinical scenarios of nonvariceal UGIB.

Alternate MHC I Antigen Presentation Pathways Allow CD8+ T-cell Recognition and Killing of Cancer Cells in the Absence of β2M or TAP.

MHC I antigen presentation allows CD8+ T cells to detect and eliminate cancerous or virally infected cells. The MHC I pathway is not essential for cell growth and viability, so cancers and viruses can evade control by CD8+ T cells by inactivating antigen presentation. In cancers, two common ways for this evasion are the loss of either the MHC I light chain [β2 microglobulin (β2M)] or the transporter-associated with antigen processing (TAP).

User preferences for an mHealth app to support HIV testing and pre-exposure prophylaxis uptake among men who have sex with men in Malaysia.

Recent estimates report a high incidence and prevalence of HIV among men who have sex with men (MSM) in Malaysia. Mobile apps are a promising and cost-effective intervention modality to reach stigmatized and hard-to-reach populations to link them to HIV prevention services (e.g.

Implementation Science and Pediatric Diabetes: A Scoping Review of the State of the Literature and Recommendations for Future Research.

Recent Findings: Of 23 papers identified, 19 were published since 2017 and 21 focused on type 1 diabetes. Most involved medical evidence-based practices (EBPs; n = 15), whereas fewer focused on psychosocial (n = 7) and diabetes education (n = 2).

A burden of rare copy number variants in obsessive-compulsive disorder.

Current genetic research on obsessive-compulsive disorder (OCD) supports contributions to risk specifically from common single nucleotide variants (SNVs), along with rare coding SNVs and small insertion-deletions (indels). The contribution to OCD risk from rare copy number variants (CNVs), however, has not been formally assessed at a similar scale. Here we describe an analysis of rare CNVs called from genotype array data in 2248 deeply phenotyped OCD cases and 3608 unaffected controls from Sweden and Norway.

Quantifying and mitigating motor phenotypes induced by antisense oligonucleotides in the central nervous system.

Antisense oligonucleotides (ASOs) are emerging as a promising class of therapeutics for neurological diseases. When injected directly into cerebrospinal fluid, ASOs distribute broadly across brain regions and exert long-lasting therapeutic effects. However, many phosphorothioate (PS)-modified gapmer ASOs show transient motor phenotypes when injected into the cerebrospinal fluid, ranging from reduced motor activity to ataxia or acute seizure-like phenotypes.

Repetitive transcranial magnetic stimulation alleviates motor impairment in Parkinson's disease: association with peripheral inflammatory regulatory T-cells and SYT6.

Background: Repetitive transcranial magnetic stimulation (rTMS) has been used to treat various neurological disorders. However, the molecular mechanism underlying the therapeutic effect of rTMS on Parkinson's disease (PD) has not been fully elucidated. Neuroinflammation like regulatory T-cells (Tregs) appears to be a key modulator of disease progression in PD.
