AI Article Synopsis

  • * The study involved 289 US adults, through telephone surveys, examining the perceived suitability of environments compared to objective measures.
  • * Results showed that while physical environment questions had moderate to high reliability, social environment questions were less reliable, with variations in reliability based on urban or rural settings.

Article Abstract

Objectives: We tested the reliability of 3 instruments that assessed social and physical environments.

Methods: We conducted a test-retest study among US adults (n = 289). We used telephone survey methods to measure suitableness of the perceived (vs objective) environment for recreational physical activity and nonmotorized transportation.

Results: Most questions in our surveys that attempted to measure specific characteristics of the built environment showed moderate to high reliability. Questions about the social environment showed lower reliability than those that assessed the physical environment. Certain blocks of questions appeared to be selectively more reliable for urban or rural respondents.

Conclusions: Despite differences in content and in response formats, all 3 surveys showed evidence of reliability, and most items are now ready for use in research and in public health surveillance.

Purpose: To investigate the effects of compression therapy combined with exercise for cancer patients (EXCAP) in patients with peripheral neuropathy caused by breast cancer chemotherapy.

Methods: Overall, 108 patients with peripheral neuropathy after chemotherapy for breast cancer were randomly divided into the control group (routine nursing), experimental group 1 (compression therapy), and experimental group 2 (compression therapy and EXCAP). The National Institute of Cancer Drug Toxicity Rating Scale and the Chemotherapy-Induced Peripheral Neuropathy Assessment Tool were assessed and compared between groups.

School built environment and children's health: a scientometric analysis.

Rev Environ Health

January 2025

School of Architecture and Design, Harbin Institute of Technology, Harbin, China.

The school built environment is closely related to children's health, and research on this topic is increasing. However, bibliometric analyses seeking to provide a comprehensive understanding of the research landscape and key themes in the field are lacking. This study comprehensively explored the global trends and research hotspots on the associations between school built environment and children's health.

Background: A number of efforts have been made to tailor behavioral healthcare treatments to the variable needs of patients with low back pain (LBP). The most common approach involves the STarT Back Screening Tool (SBST) to triage the need for psychologically informed care, which explores concerns about pain and addresses unhelpful beliefs, attitudes, and behaviors. Such beliefs that pain always signifies injury or tissue damage and that exercise should be avoided have been implied as psychosocial mediators of chronic pain and can impede recovery.

Background: Nonweightbearing preoperative assessments avoid quadriceps contraction that tends to affect patellar motion and appear to be inaccurate in quantifying anatomic factors, which can lead to incorrect corrections and postoperative complications.

Questions/purposes: (1) Does the relationship of patellar axial malalignment and other anatomic factors change during weightbearing? (2) What anatomic factor was most strongly correlated with recurrent patellar dislocation during weightbearing?

Methods: This prospective, comparative, observational study recruited participants at our institution between January 2023 and September 2023. During this time, all patients with recurrent patellar dislocations received both weightbearing and nonweightbearing CT scans; control patients who received unilateral CT scans because of injuries or benign tumors received both weightbearing and nonweightbearing CT scans.
