Introduction: This study aimed to identify cognitive tests that optimally relate to tau positron emission tomography (PET) signal in the inferior temporal cortex (ITC), a neocortical region associated with early tau accumulation in Alzheimer's disease (AD).
Methods: We analyzed cross-sectional data from the harvard aging brain study (HABS) (= 128) and the Anti-Amyloid Treatment in Asymptomatic Alzheimer's (A4) study (= 393). We used elastic net regression to identify the most robust cognitive correlates of tau PET signal in the ITC.

Constipation is correlated with diminished cognitive function, revealing a possible rectum-brain connection. In this counter-balanced crossover trial, 13 elite triathletes underwent a Stroop test to assess cognitive function and executive control. The Stroop test was conducted both with and without magnesium oxide intake, with a 1-week washout period between sessions.

A 52-year-old female patient with a history of atrial septal defect repair presented with progressive dyspnea and echocardiographic findings suggestive of pulmonary hypertension (PH). Incidentally, a lung mass was discovered on computed tomography (CT). Initial evaluation revealed World Health Organization functional class III symptoms and significant weight loss.

The principle of independence is a fundamental yet often disregarded assumption in statistical inference. It is observed that the implications of correlations, if not considered, can lead to a conservative estimation of Type I error in the presence of positive linear correlations when utilizing the Kolmogorov-Smirnov (KS) test. Conversely, negative linear correlations may engender a liberal estimation of Type I error.

Introduction: The aim of this study was to describe the clinical features and treatment responses of Rosai-Dorfman disease (RDD) and Erdheim-Chester disease (ECD) with kidney involvement.
Methods: We retrospectively analyzed patients with RDD and ECD with kidney involvement from 2005 to 2023, evaluating kidney function changes, as well as computed tomography (CT), and metabolic responses.
Results: The study included 4 patients with RDD and 44 with ECD, with median ages of 58 and 51 years, respectively.
