Objective: To better characterize associations between physical risk factors and upper-extremity musculoskeletal symptoms and disorders, a prospective epidemiologic study of 386 manufacturing workers was performed.
Background: Methodological limitations of previous studies have resulted in inconsistent associations.
Method: An individual, task-based exposure assessment strategy was used to assess upper-extremity exertion intensity, repetition, and time-in-posture categories. Participants recorded time spent performing daily work tasks on a preprinted log, which was then used to calculate time-weighted-average exposures across each week of follow-up. In addition, a weekly Strain Index (SI) risk category was assigned to each participant. Incident musculoskeletal symptoms and disorders were assessed weekly. Proportional hazards analyses were used to examine associations between exposure measures and incident hand/arm and neck/shoulder symptoms and disorders.
Results: Incident symptoms and disorders were common (incident hand/arm symptoms = 58/100 person-years (PY), incident hand/arm disorders = 19/100 PY, incident neck/shoulder symptoms = 54/100 PY, incident neck/shoulder disorders = 14/100 PY). Few associations between separate estimates of physical exposure and hand/arm and neck/shoulder outcomes were observed. However, associations were observed between dichotomized SI risk category and incident hand/arm symptoms (hazard ratio [HR] = 1.73, 95% confidence interval [CI] = [0.99, 3.04]) and disorders (HR = 1.93,95% CI = [0.85,4.40]).
Conclusion: Evidence of associations between physical risk factors and musculoskeletal outcome was strongest when exposure was estimated with the SI, in comparison to other metrics of exposure.
Application: The results of this study provide evidence that physical exposures in the workplace contribute to musculoskeletal disorder incidence. Musculoskeletal disorder prevention efforts should include mitigation of these occupational risk factors.

The value of non-punctate echogenic foci in the ultrasonic diagnosis of thyroid nodules.
Endocrine
January 2025
Department of General Surgery, Tianjin Medical University General Hospital, Tianjin, China.
Purpose: To evaluate the diagnostic value of different subtypes of non-punctate echogenic foci in thyroid malignancy.
Methods: Retrospective research of 342 thyroid nodules with calcification was performed. The echogenic foci were divided into punctate echogenic foci (type I) and non-punctate echogenic foci (type II), and type II were further divided into four subtypes: macrocalcification (type IIa), continuous peripheral calcification (type IIb), discontinuous peripheral calcification (type IIc) and isolated calcification (type IId).
Incidence and Risk Factors for Amiodarone-Induced Thyroid Dysfunction: A Nationwide Retrospective Cohort Study.
Am J Cardiovasc Drugs
January 2025
Division of Cardiology, Department of Internal Medicine, Ilsan Paik Hospital, Inje University College of Medicine, Goyang, Republic of Korea.
Background: Amiodarone is an effective anti-arrhythmic drug; however, it is frequently associated with thyroid dysfunction. The aim of this study was to investigate the incidence and risk factor of amiodarone-induced dysfunction in an iodine-sufficient area.
Methods: This retrospective cohort study included 27,023 consecutive patients treated with amiodarone for arrhythmia, using the Korean National Health Insurance database.
Physical Activity Amid a Pandemic: How Socioeconomic and Demographic Factors Shaped Behaviors During COVID-19.

Fay W. Boozman College of Public Health, University of Arkansas for Medical Sciences, Little Rock, AR, 72205, USA.
The COVID-19 pandemic led to significant shifts in societal norms and individual behaviors, including changes in physical activity levels. This study examines the relationship between socioeconomic and sociodemographic factors and changes in physical activity levels during the pandemic compared to pre-pandemic levels among adult Arkansans. Survey data were collected from 1,205 adult Arkansans in July and August 2020, capturing socioeconomic and sociodemographic characteristics and information on physical activity changes since the onset of the pandemic.

Introduction: Total joint arthroplasties generally achieve good outcomes, but chronic pain and disability are a significant burden after these interventions. Acknowledging relevant risk factors can inform preventive strategies. This study aimed to identify chronic pain profiles 6 months after arthroplasty using the ICD-11 (International Classification of Diseases) classification and to find pre and postsurgical predictors of these profiles.
