Working Conditions in Complementary and Integrative Healthcare Professions.
J Occup Environ Med
January 2025
From the Behavioral and Policy Sciences, RAND, Santa Monica, California (M.D.W.); Research Department, National University of Health Sciences, Lombard, Illinois (J.F., D.M.); School of Public Health, Environmental and Occupational Health Sciences, University of Illinois Chicago, Chicago, Illinois (D.M.); Whole Health, Central Texas Veterans Health Care System, Austin, Texas (J.S,F.); and Research Institute, Bastyr University, Kenmore, Washington State (J.S.F.).
Objective: The study aimed to describe working conditions among complementary and integrative healthcare (CIH) providers, specifically acupuncturists, chiropractors, massage therapists, midwives, and naturopathic doctors.
Methods: We used cross-sectional Occupational Information Network data (2013-2021) for five CIH occupations. We examined means and 95% confidence intervals (CIs) for 10 variables that represented positive conditions, ergonomic demands, psychosocial demands, and schedule demands.

Article Synopsis
- Polyacrylamide (PAM) is a durable polymer that doesn’t break down easily, leading to environmental issues due to its accumulation.
- A study identified two key enzymes (amidohydrolases) in Klebsiella sp. PCX that effectively degrade PAM, outperforming many smaller compounds.
- The researchers also determined the structures of these enzymes and pinpointed specific active sites that facilitate their function, which can aid in future PAM bioremediation efforts.
Protein Biomarkers of Ultra-Processed Food Consumption and Risk of Coronary Heart Disease, Chronic Kidney Disease, and All-Cause Mortality.

Background: There is a need to understand the underlying biological mechanisms through which ultra-processed foods negatively affect health. Proteomics offers a valuable tool with which to examine different aspects of ultra-processed foods and their impact on health.
Objectives: The aim of this study was to identify protein biomarkers of usual ultra-processed food consumption and assess their relation to the incidence of coronary heart disease (CHD), chronic kidney disease (CKD), and all-cause mortality risk.
Clinical Implications of Left Ventricular Apex Mechanics in Patients With Apical Hypertrophic Cardiomyopathy.
J Am Soc Echocardiogr
December 2024
Department of Medical Ultrasound, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China. Electronic address:
Background: Apical hypertrophic cardiomyopathy (ApHCM) is a unique disease with pathologic hypertrophy mainly at the left ventricular (LV) apex. Although previous studies have indicated apical dysfunction in ApHCM, how apical mechanics change during disease progression has not been thoroughly examined. The aims of this study were to characterize the mechanics of the LV apex in patients with ApHCM at different disease stages and to explore the clinical significance of these alterations.

Department of Mechanical Engineering, City University of Hong Kong, Hong Kong, China.
Microactuators, capable of executing tasks typically repetitive, hazardous, or impossible for humans, hold great promise across fields such as precision medicine, environmental remediation, and swarm intelligence. However, intricate motions of microactuators normally require high complexity in design, making it increasingly challenging to realize at small scales using existing fabrication techniques. Taking inspiration from the hierarchical-anisotropy principle found in nature, we program liquid crystalline elastomer (LCE) microactuators with multimodal actuation tailored to their molecular, shape, and architectural anisotropies at (sub)nanometer, micrometer, and (sub)millimeter scales, respectively.
