Objective: To explore the potential predictors of people with Parkinson disease (PD) who would benefit the most from treadmill training.

Design: A cohort study.

Setting: Medical university rehabilitation settings.

Participants: Seventy participants diagnosed of idiopathic PD.

Interventions: Twelve sessions of treadmill training.

Main Outcome Measures: Hierarchical logistic regression models were used to explore significant predictors of the treadmill training effect with respect to 3 health domains: Unified Parkinson's Disease Rating Scales part III (UPDRS III); gait speed; Parkinson's Disease Questionnaire-39 (PDQ-39). A receiver operating characteristic (ROC) curve analysis was conducted to identify proper cut-off points for clinical use.

Results: Male sex (adjusted odds ratio [OR]: 3.73, P=.036) significantly predicted the improvement of UPDRS III. Individuals with a slower baseline gait speed (cut-off: 0.92 m/s, adjusted OR: 14.06, P<.001) and higher baseline balance confidence measured by the Activity-specific Balance Confidence scale (cut-off: 84.5 points, adjusted OR: 4.66, P=.022) have greater potential to achieve clinically relevant improvements in gait speed. A poorer baseline PDQ-39 score (cut-off: 23.1, adjusted OR: 7.47, P<.001) predicted a greater quality of life improvement after treadmill training.

Conclusions: These findings provide a guideline for clinicians to easily identify suitable candidates for treadmill training. Generalization to more advanced patients with PD warrants further investigation.

Objective: This study investigates the relationship between the albumin-to-creatinine ratio and diabetic retinopathy (DR) in US adults using NHANES data from 2009 to 2016. This study assesses the predictive efficacy of the urinary serum albumin-to-creatinine ratio (UACR/SACR Ratio) against traditional biomarkers such as the serum albumin-to-creatinine ratio (SACR) and urinary albumin-to-creatinine ratio (UACR) for evaluating DR risk. Additionally, the study explores the potential of these biomarkers, both individually and in combination with HbA1c, for early detection and risk stratification of DR.

Criminal victimization is associated with an increased risk of violent offending, which can be motivated by revenge. Experiencing revenge desire could also be harmful for crime victims' mental health. To limit revenge's harmful effects, researchers have examined the predictors of revenge desire and attitudes.

Low Utility of Routine Thyroid Function Testing for Bowel Symptoms: A Population-Based Assessment.

Dig Dis Sci

January 2025

Division of Gastroenterology, Hepatology and Endoscopy, Brigham and Women's Hospital, 75 Francis Street, Boston, MA, 02115, USA.

Background: Chronic constipation, diarrhea, and fecal incontinence (FI) are prevalent with significant impact on quality of life and healthcare utilization. Thyroid dysfunction was recognized as a potential contributor to bowel disturbances in selected populations, but the strength/consistency of this association remain unclear.

Aims: To investigate the relationship between thyroid function and bowel health measures (constipation, diarrhea, and FI) in a nationally representative sample of the U.

UV-A exposure is a major risk factor for melanoma, nonmelanoma skin cancer, photoaging, and exacerbation of photodermatoses. Since people spend considerable time in cars daily, inadequate UV-A attenuation by car windows can significantly contribute to the onset or exacerbation of these skin diseases. Given recent market trends in the automobile industry and known impact of car windows on cumulative lifelong UV damage to the skin, there is a need to comparatively evaluate UV transmission across windows in electric vehicles (EV), hybrid vehicles (HV), and gas vehicles (GV) as well as variability based on year of manufacture and mileage to inform car manufacturers and consumers of the potential for UV exposure to the skin based on vehicle.

Introduction: Cancer patients often face challenges in managing their disease, particularly with regard to contraindications related to medications, foods, and physical activity, which can negatively affect treatment outcomes. This study aimed to evaluate cancer patients' awareness of these contraindications and to explore the influence of sociodemographic factors, support systems, comorbidities, and medication use on their knowledge.

Methods: A cross-sectional prospective study was conducted with 125 cancer patients in Saudi Arabia between December 2022 and February 2023.
