Article Abstract

Importance: Limited evidence exists to support cognitive intervention improving the daily function of adults with subjective cognitive decline (SCD).

Objective: To examine the preliminary efficacy of a group-based multicomponent cognitive intervention that integrates Lifestyle Redesign® (LR) techniques.

Design: Single-arm two-period crossover trial; 16-wk waiting period, 16-wk intervention, and 16-wk follow-up.

Setting: Memory clinic in a medical center, Taiwan.

Participants: Purposive sample of adults ages >55 yr with SCD.

Intervention: Sixteen 1.5-hr weekly multicomponent sessions of cognitive training, cognitive rehabilitation, psychological intervention, and lifestyle intervention.

Outcomes And Measures: Primary outcomes were (1) self-reported daily function, measured with the Activities of Daily Living Questionnaire (ADLQ) and Cognitive Failure Questionnaire; (2) performance-based daily function, measured with the Brief University of California San Diego Performance-Based Skills Assessment-Traditional Chinese Version; and (3) functional cognition, measured with the Contextual Memory Test (CMT) and Miami Prospective Memory Test. Secondary outcomes included cognitive functions, anxiety, and depression.

Results: Seventeen participants completed the intervention; 4 missed the follow-up. The generalized estimating equations model showed significant changes from baseline to pretest (control) and pretest to posttest (intervention) on the ADLQ (p = .014) and CMT-delayed (p = .003). Effects remained at the 16-wk follow-up. After adjusting for the effects of covariates, the self-reported daily function of participants ages ≤ 63 yr improved more than that of other participants (p = .003).

Conclusions And Relevance: Multicomponent cognitive interventions integrating LR techniques may improve self-reported daily function and context-dependent memory function of adults with SCD, with efficacy sustained at follow-up. What This Article Adds: A group-based multicomponent cognitive intervention consisting of cognitive training, cognitive rehabilitation, psychoeducation, and lifestyle intervention may provide benefits for the daily function and cognitive function of adults with SCD.

Background: Survivors of critical illness frequently face physical, cognitive and psychological impairments after intensive care. Sensorimotor impairments potentially have a negative impact on participation. However, comprehensive understanding of sensorimotor recovery and participation in survivors of critical illness is limited.

Background: Post-viral syndromes, including long- and post-COVID, often lead to persistent symptoms such as fatigue and dyspnoea, affecting patients' daily lives and ability to work. The COVI-Care M-V trial examines whether interprofessional, patient-centred teleconsultations, initiated by general practitioners in cooperation with specialists, can help reduce symptom burden and improve care for patients.

Methods: To evaluate the effectiveness of the intervention under routine care conditions, a cluster-randomised controlled trial is being conducted.

Background: Surgical resection is the cornerstone for early-stage non-small cell lung cancer (NSCLC), with lobectomy historically standard. Evolving techniques have spurred debate comparing lobectomy and segmentectomy. This study analyzed early postoperative patient-reported symptoms and functional status in patients with early NSCLC undergoing either procedure.

A ketogenic diet (KD) has shown promise as an adjunctive therapy for neurological and neuropsychiatric disorders, including bipolar disorder and major depressive disorder (MDD). We examined tolerance for a KD in young adults with MDD and assessed symptoms of depression and metabolic health. Students (n = 24) with a confirmed diagnosis of MDD at baseline receiving standard of care counseling and/or medication treatment were enrolled in a 10-12 week KD intervention that included partial provision of ketogenic-appropriate food items, frequent dietary counseling, and daily morning tracking of capillary R-beta-hydroxybutyrate (R-BHB).

ROSAH (retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis, and headache) syndrome is a rare genetic disease caused by variants in alpha-kinase 1 (ALPK1) resulting in downstream pro-inflammatory signaling mediated by the TIFA/TRAF6/NF-κB pathway. Here, we report the design of an ALPK1 inhibitor, DF-003, with pharmacokinetic properties suitable for daily oral dosing. In biochemical assays, DF-003 potently inhibits human ALPK1 (IC = 1.
