Office Massage Effects on HRV and Stress

This study is a randomized controlled trial designed to investigate which of three short office massage types (head, neck/shoulder area, or hand) is most effective for reducing chronic stress in women who perform sedentary office work. Many sedentary female office employees experience long-term tension and work-related strain, which can affect the body's ability to recover. The investigators are testing whether a 15-minute massage, performed twice a week for four weeks, can help restore balance within the body. The investigators will evaluate the impact of these massages using Heart Rate Variability (HRV)-an objective measure that shows how well the body manages stress (autonomic nervous system balance)-as well as analyzing participants' self-reported levels of perceived stress, sleep quality, and overall well-being. Participants receiving massage will be compared to a control group engaging in quiet rest.

Non-Invasive System to Deliver Therapeutic Hypothermia for Protection Against Noise-Induced Hearing Loss

The goal of this interventional clinical study is to investigate the use of mild therapeutic hypothermia devices for preservation of sensory structures in the cochlea after noise exposure. The main aims of the study are: 1. To test the safety and best duration for use for a new hypothermia device. 2. To determine if the hypothermia device helps decrease noise-induced hearing loss in a group of firefighters. Participants will wear the mild therapeutic hypothermia therapy devices immediately after a fire service shift serially over a year. Researchers will compare results from those receiving the therapy to those from a control group (individuals receiving no therapy and a sham therapy).

Feasibility and Preliminary Effects of a Tele-Education-Based Ergonomic and Hand Exercise Program in Office Workers

Many office workers spend long hours at desks, which can lead to hand and upper limb problems. These issues may reduce hand strength and affect daily activities and work performance. This study will evaluate whether an online ergonomic training and hand exercise program is practical and helpful for desk-based workers over four weeks. Researchers will measure hand grip strength and fine motor skills before and after the program to assess its potential benefits.

Implementation of the ASCEND Training for Supervisors in Dutch Small and Medium-sized Enterprises (SMEs)

This cluster randomized controlled trial (cRCT) aims to evaluate the effectiveness of the Dutch adaptation of an in-person group intervention for workplace supervisors - Advancing Supervisors' Capacity for Mental Health at Work (ASCEND) - in Dutch Small and Medium-sized Enterprises (SMEs). The ASCEND intervention is designed to equip supervisors with the skills to: i) know when to support their workers; ii) how to direct workers to support, and iii) advocate for action on mental health at work. The primary objectives of this project are to: * Assess to what extent the Dutch adaptation of the WHO-developed ASCEND intervention is effective in enhancing supervisors' confidence, responsiveness, mental health literacy, and self-care practices, and in reducing supervisor stigma towards mental health conditions within Dutch SMEs. * Evaluate the impact of the ASCEND intervention on employee outcomes, including mental health and work-related outcomes among supervisees (i.e., subordinates), as well as overall organizational absenteeism rates. * Identify barriers, facilitators, and key implementation and adoption indicators to support future opportunities for scaling up the ASCEND intervention. Researchers will compare two groups to evaluate the effectiveness of the ASCEND intervention. One group will receive the training (the intervention group), while the other group will receive the training after the final follow-up period (the control group). Data will be collected from both supervisors and their supervisees (i.e., subordinates) via online questionnaires at various time points. In addition, general organizational information, including absenteeism rates, will be gathered through a representative from each participating organization. To further explore the feasibility of scaling up the ASCEND intervention within the Netherlands, qualitative data will be collected through interviews and/or focus group discussions.

Reducing Pain-Related Sickness Absence Through Workplace Health Literacy: A Hybrid II Study

The primary aim of this study is investigate whether a workplace intervention targeting employees' and managers' understanding of pain and communication (called occupational health literacy) can reduce pain-related sick leave and help employees and managers to better understand and manage work-related health matters. The study also aims to learn how the program works, who it works best for (or not), and how it can be successfully used long-term in real workplaces, especially in production environments. The study will e.g. examine whether the program: * reduces the number of sick days caused by pain, * lowers how much pain employees feel, and * improves employees' and managers' understanding of health and how to improve it. Expectation: Employees who participate in the program will: * take fewer sick days because of pain, * experience less pain, and have better health knowledge and skills than employees who continue with normal workplace practices. The study will identify: * what makes the program difficult or easy to introduce at workplaces, * which strategies help it succeed, and * what factors make the program continue working over time. Goal: Help workplaces adopt and maintain the program successfully.

Work-Related Health Factors in General and Special Education Teachers

This cross-sectional study aims to compare work-related health outcomes between general education teachers and special education teachers. The study will assess burnout, occupational balance, perceived stress, musculoskeletal symptoms, pain characteristics, and general job satisfaction. Participants will complete an online questionnaire including sociodemographic and occupational characteristics, such as age, sex, teaching experience, working hours, and type of teaching assignment. Standardized self-report measures will be used to evaluate burnout, occupational balance, perceived stress, musculoskeletal symptoms, and pain-related characteristics. The study will examine whether teachers working in special education differ from general education teachers in terms of burnout, stress, occupational balance, musculoskeletal problems, and pain. The findings may help identify occupational health needs among teachers and support the development of preventive strategies for improving their well-being and working conditions.

Workplace Violence and Safety Perception Among ENT Physicians in Turkey

This multicenter, cross-sectional survey study aims to evaluate the perceived level of safety and security against workplace violence among otolaryngology-head and neck surgery (ENT-HNS) physicians in Turkey. The study investigates the association between exposure to workplace violence and perceived safety, as well as the adequacy of institutional support mechanisms. Data will be collected through an anonymous online questionnaire distributed nationwide. The findings are expected to contribute to awareness and the development of preventive strategies and institutional safety policies for healthcare professionals.
