Performance of SARC-F and SARC-CalF scores to predict risk of mortality in hemodialysis patients: a cohort study.

This study aimed to evaluate the association between the questionnaires SARC-F and SARC-CalF with risk of mortality in patients undergoing hemodialysis (HD). A cohort study, with patients on HD age ≥ 18 years, both sex, between June 2019 and April 2023. Body composition (anthropometry and bioelectrical impedance), muscle functional (handgrip strength and gait speed), screening of sarcopenia using the SARC-F and SARC-CalF, nutritional status and laboratory data were assessed.

Respiratory sarcopenia screening in dialysis patients: cross-sectional and multicentre study protocol.

Background: Respiratory sarcopenia is characterized by the weakness of respiratory muscles associated with sarcopenia due to aging or systemic diseases such as chronic kidney disease (CKD). Patients with CKD undergoing dialysis are particularly susceptible to respiratory muscle weakness caused by factors such as fluid overload and electrolyte imbalance. This weakness not only affects ventilation but also impairs oxygen uptake and delivery to muscle tissue, potentially leading to severe sarcopenia.

Green photocatalytic remediation of Fenthion using composites with natural red clay and non-toxic metal oxides with visible light irradiation.

In the present work, composites with non-toxic metal oxides, such as TiO and ZnO, and a natural red clay () reach in hematite were used in the photocatalytic degradation of Fenthion. The composite TiO/Taua (0.5:1 wt.

Correlation between functional mobility and cognitive performance in older adults with cognitive impairment.

Association between cognitive impairment and gait performance occurs in mild cognitive impairment (MCI) and Alzheimer's disease (AD), particularly under "divided attention" conditions, leading to a greater risk of falls. We studied 36 controls, 42 MCI, and 26 mild AD patients, using the Timed Up-and-Go test (TUG) under four conditions: TUG single - TUG1; TUG cognitive - TUG2; TUG manual -TUG3; TUG cognitive and manual - TUG4. Cognition was assessed using the MMSE, SKT, Exit25, and TMT (A and B).

Functional mobility in a divided attention task in older adults with cognitive impairment.

Motor disorders may occur in mild cognitive impairment (MCI) and at early stages of Alzheimer's disease (AD), particularly under divided attention conditions. We examined functional mobility in 104 older adults (42 with MCI, 26 with mild AD, and 36 cognitively healthy) using the Timed Up and Go test (TUG) under 4 experimental conditions: TUG single task, TUG plus a cognitive task, TUG plus a manual task, and TUG plus a cognitive and a manual task. Statistically significant differences in mean time of execution were found in all four experimental conditions when comparing MCI and controls (p < .

Fear of falling and falls in older adults with mild cognitive impairment and Alzheimer's disease.

Cognitive impairment and fear of falling are risk factors for falls in older adults. Recurrent falls are more prevalent in older adults with cognitive impairment. We examined the number of previous falls, self-reported fear of falling, and the Falls Efficacy Scale-International (FES-I) in 104 older adults [26 with mild Alzheimer's disease (AD), 42 with mild cognitive impairment (MCI) and 36 cognitively healthy].

Itraconazole vs. trimethoprim-sulfamethoxazole: A comparative cohort study of 200 patients with paracoccidioidomycosis.

Paracoccidioidomycosis (PCM) is a systemic mycosis endemic to Latin America. Brazil accounts for approximately 80% of cases, where it represents a major public health issue due to its disabling impact and the number of premature deaths it causes. We present a retrospective cohort study that was conducted in order to better understand factors that relate to cure of the infection in the treatment of 200 patients with PCM.

Effects of a multidisciplinary cognitive rehabilitation program for patients with mild Alzheimer's disease.

Objective: To evaluate the effects of a multidisciplinary rehabilitation program on cognition, quality of life, and neuropsychiatry symptoms in patients with mild Alzheimer's disease.

Method: The present study was a single-blind, controlled study that was conducted at a university-based day-hospital memory facility. The study included 25 Alzheimer's patients and their caregivers and involved a 12-week stimulation and psychoeducational program.
