The goal of this study was to systematically examine alterations underlying the graphical copying performance of Alzheimer's patients at different stages of cognitive decline, in light of a theoretical framework of visuoconstructional processing (Guérin, Ska, & Belleville, 1999). Eight patients with a diagnosis of probable Alzheimer's disease were studied. A group of 24 elderly subjects, of similar age to the patient group and slightly higher education, served as controls. The severity of the cognitive decline of each patient was measured with a standard neuropsychological battery. All subjects were administered a copying task and tasks measuring visual exploration, judgment of spatial relations and graphical planning. Group and individual results were analyzed. The group results suggested that visuoconstructional apraxia in patients with Alzheimer's type dementia is characterized by impaired visual exploration and judgment of spatial relations. Individual results revealed between-patient variability related to the severity of cognitive decline. Given the small number of patients, these observations need to be replicated with a larger-scaled study.

Urogynecology (Phila)
December 2024
From the Urogynecology and Reconstructive Pelvic Surgery, MedStar Washington Hospital Center/Georgetown University, Washington, DC.
Importance: Strong evidence demonstrates long-term cognitive decline associated with anticholinergics. While prevalent among older populations, medical management of overactive bladder (OAB) is dictated by insurance coverage rather than medical provider and patient preferences.
Objective: The aim of this study was to assess Medicare insurance plan coverage for select OAB medications and evaluate coverage of preferred medications to medications with a greater risk of cognitive dysfunction.
Wounds resulting from intradermal injection of sodium hypochlorite: a case report.
Wounds
December 2024
Dermatology Unit, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy; Department of Medical and Surgical Sciences, Alma Mater Studiorum University of Bologna, Bologna, Italy.
Background: Caustic substances can inflict severe damage on tissues upon contact. Knowledge about skin damage caused by sodium hypochlorite is quite limited, with only a few reports available in the literature.
Case Report: A 79-year-old female with severe cognitive decline presented with multiple skin ulcerations that were covered by a blackish-greyish eschar and surrounded by a purple erythematous halo.
Covert Vascular Brain Injury and Cognitive Dysfunction Among Chinese Adults Living in Canada and China: The CAHHM and PURE-MIND Studies.
Neurology
February 2025
Department of Medicine, University of Toronto, Canada.
Background And Objective: It is unclear whether variation in covert cerebrovascular disease prevalence is attributable to ethnic differences or to other factors. We aimed to examine the associations of country of residence with covert vascular brain injury (VBI) and cognitive dysfunction among Chinese adults residing in Canada and China.
Methods: This was a multisite cross-sectional study of Chinese adults aged 40-80 years in the Canadian Alliance for Healthy Hearts and Healthy Minds (CAHHM; January 1, 2014, to December 31, 2018) and Prospective Urban Rural Epidemiological-Mind (PURE-MIND; November 1, 2010, to July 31, 2015) cohorts living in Canada and China.
High Prevalence of Malnutrition in Geriatric Patients With Solid Organ Cancer-An Institutional Study.
JCO Glob Oncol
January 2025
Department of Geriatric Medicine, All India Institute of Medical Sciences, Rishikesh, India.
Purpose: The demographic transition toward aging heralds an increase in the number of geriatric patients with cancer in India. Comprehensive geriatric assessment (CGA) is a sine qua non for treatment planning and shared decision making in these patients. We aimed to study the prevalence of malnutrition and the associated risk factors in geriatric patients with solid organ cancer.
