Unlabelled: The newly proposed revised criteria for diagnosis and staging of Alzheimer's disease (AD) by the Alzheimer's Association (AA) Workgroup represent a significant milestone in the field. These criteria offer objective measures for diagnosing and staging biological AD, bridging the gap between research and clinical care. Although implementation feasibility may vary across regions and settings, improving the availability and accuracy of biomarkers, especially plasma biomarkers, is expected to enhance the applicability of these criteria in clinical practice.

Objective: To report the development and performance of 2 distinct deep learning models trained exclusively on retinal color fundus photographs to classify Alzheimer disease (AD).

Patients And Methods: Two independent datasets (UK Biobank and our tertiary academic institution) of good-quality retinal photographs derived from patients with AD and controls were used to build 2 deep learning models, between April 1, 2021, and January 30, 2024. ADVAS is a U-Net-based architecture that uses retinal vessel segmentation.

Biomarkers in the diagnosis of mast cell activation.

Curr Opin Allergy Clin Immunol

February 2025

Division of Allergic Diseases, Mayo Clinic Rochester, Rochester, Minnesota, USA.

Purpose Of Review: Mast cell activation is defined by activation of mast cells by varying stimuli with release of chemical mediators either through degranulation or release of de novo synthesized proteins or lipid mediators. Currently, tryptase measurement increase during symptomatic episodes is the most accepted biomarker measurement for mast cell activation. However, newer diagnostic tools including clinically available urinary mast cell mediators are noninvasive and can be more readily obtained compared to serum tryptase levels.

Purpose Of Review: Peyronie's disease characterizes a condition in which there is angular curvature of the penis. We know that the most patients with Peyronie's disease will not have spontaneous resolution of their penile curvature. As such, patients who desire treatment can elect for either surgical or nonsurgical therapy.

Archived FFPE cardiac tissue specimens are valuable for molecular studies aimed at identifying biomarkers linked to mortality in cardiovascular disease. Establishing a reliable and reproducible RNA extraction method is critical for generating high-quality transcriptome sequences for molecular assays. Here, the efficiency of four RNA extraction methods: Qiagen AllPrep DNA/RNA method (Method QP); Qiagen AllPrep DNA/RNA method with protocol modification on the ethanol wash step after deparaffinization (Method QE); CELLDATA RNA extraction (Method BP) and CELLDATA RNA extraction with protocol modifications on the lysis step (Method BL) was compared on 23 matching FFPE cardiac tissue specimens (n = 92).

Portopulmonary hypertension (POPH), a form of pulmonary artery hypertension, occurs because of portal hypertension. Pulmonary hemodynamics and right heart function are key entities that are considered when diagnosing and treating POPH. Medical management, combined with liver transplantation, offers a unique opportunity of POPH "cure," however transplant risk can be significant as it relates to the severity of POPH.

Background: This study aims to characterize right ventricular dysfunction (RVD) in heart failure (HF) with preserved ejection fraction and understand the cumulative prognostic value of abnormal RV echocardiographic parameters in HF with preserved ejection fraction.

Methods And Results: Data from 809 patients in the PARAGON-HF (Prospective Comparison of Angiotensin Receptor-Neprilysin Inhibitor With Angiotensin-Receptor Blocker Global Outcomes in HF With Preserved Ejection Fraction) echocardiographic substudy (55% women, mean age 74±8 years) were analyzed. Correlates of RVD (defined as tricuspid annular plane systolic excursion <1.

Background: Patients with palliated pulmonary valve stenosis (PVS) have less cardiac remodeling and symptoms as compared to patients with repaired tetralogy of Fallot (TOF) presenting with similar severity of right ventricular outflow tract (RVOT) disease. What is not known is whether patients with PVS versus TOF presenting with similar severity of RVOT disease at baseline, would have similar (or different) pace of cardiac remodeling and disease progression over time. The study objective was to compare temporal changes in clinical and cardiac function indices between adults with palliated PVS and repaired TOF presenting with moderate/severe RVOT disease.

Background: Right atrial (RA) dysfunction and atrial arrhythmias are relatively common in adults with repaired tetralogy of Fallot. The purpose of this study was to determine whether RA function improved after surgical pulmonary valve replacement (PVR), and the association between postoperative RA reverse remodeling and late postoperative atrial arrhythmias.

Method: RA reverse remodeling (ΔRA reservoir strain based speckle tracking echocardiography) was calculated as: ([postoperative RA reservoir strain - preoperative RA reservoir strain]/preoperative RA reservoir strain)x100.

Background: The limitations of conventional measures of socioeconomic status (SES) limit our ability to elucidate the role of SES as a key element of social determinants of health in kidney transplantation. This study's objective was to use an innovative SES measure, the HOUsing-based SES measure (HOUSES) index, to examine the effects of social determinants of health on access to and outcomes of kidney transplantation.

Methods: Our study included residents of Minnesota (age older than 18 y) who underwent kidney transplantation at a single center between 2010 and 2020.

Purpose: Meningiomas are the most common primary intracranial tumor. Somatostatin receptor 2 is almost universally expressed in meningioma tissue. For patients who require adjuvant radiation, somatostatin receptor based (68)Ga-DOTATATE positron emission tomography (PET) imaging can detect additional or residual disease not discernible on magnetic resonance imaging.

Background: The prevalence and impact of right ventricular dysfunction (RVD) in degenerative mitral regurgitation (DMR) is unknown. We aimed to determine whether RVD assessed by echocardiography in routine clinical practice is independently associated with mortality in patients with DMR.

Methods And Results: We used data from the MIDA-Q (Mitral Regurgitation International DAtabase-Quantitative) registry, which included patients with isolated DMR due to mitral valve prolapse from January 2003 to January 2020 from 5 tertiary centers across North America, Europe, and the Middle East.

Irritable bowel syndrome (IBS) is a chronic disorder of gut-brain interaction that impacts a significant portion of the population and is associated with substantial morbidity, reduced quality of life, and economic impact globally. The pathophysiology of IBS is complex and incompletely understood, and the heterogeneity of IBS is reflected in the variety of pharmaceutical and non-pharmaceutical therapies utilized for the management of IBS. Given limitations with pharmaceutical treatments, many patients with IBS seek non-pharmaceutical options.

Objective: We aim to explore the role of mechanistic target of rapamycin complex (mTORC) 2 in systemic lupus erythematosus (SLE) development, the in vivo regulation of mTORC2 by type I interferon (IFN) signaling in autoimmunity, and to use mTORC2 targeting therapy to ameliorate lupus-like symptoms in an in vivo lupus mouse model and an in vitro coculture model using human PBMCs.

Method: We first induced lupus-like disease in T cell specific Rictor, a key component of mTORC2, deficient mice by topical application of imiquimod (IMQ) and monitored disease development. Next, we investigated the changes of mTORC2 signaling and immunological phenotypes in type I IFNAR deficient Lpr mice.
