Occupational exposure in a metal industry and ventilatory lung function

U cilju odgovora na pitanje u kojoj su meri profesionalne nokse registrovane u metaloprerađivačkoj industriji (MIN) mogle uticati na stanje ventilacije pluća eksponiranih radnika sprovedena su ispitivanja u radnoj sredini 1 na radnicima. U radnoj sredini je izvršena analiza tehnološkog procesa rada, rezultata mikroklimatskih merenja, hemijskih štetnosti i zaprašenosti. Ispitivanje ventilacije pluća sprovedeno je na radnicima eksponirane grupe (129) i radnika kontrolne grupe (129). Rezultati analize radne sredine ukazuju na prisustvo sledečih respiratornih noksi iznad MDK: mineralne prašina (SiO2 do 10%) aerosoli i boje, toluol i vajšpirit, Osim ovih noksi nađene su i druge kao što su: aceton, CO, C02, nafta, S02, FeO i ZnO, ali su njihove vrednosti ispod dozvoljenih koncentracija. Ispitivanja ventilacije pluća eksponiranih radnika su pokazala statistički značajno sniženje vrednosti ispitivanih testova kod ove grupe u odnosu na kontrolnu grupu, što objašnjavamo delovanjem navedenih noksi na radnom mestu.A study was carried in a metal processing industry with the aim to analyse the relationship between occupational exposure and lung functions. Measurements in the working environment showed the presence of the following respiratory noxae exceeding MAC values: mineral dust (Si02 up to 10%), aerosols, dyes, toluol and white-spirit. The concentrations of acetone, CO, CO2, oil, SO2, FeO and ZnO, which were also determined, did not exceed permissibile concentrations. Lung function tests were performed in two groups of workers- 129 exposed and 129 control ones. The test values were significantly lower in the exposed group of workers than in controls. This is explained by the effect of the occupational noxae present

A participatory physical and psychosocial intervention for balancing the demands and resources among industrial workers (PIPPI): study protocol of a cluster-randomized controlled trial

Background: Need for recovery and work ability are strongly associated with high employee turnover, well-being and sickness absence. However, scientific knowledge on effective interventions to improve work ability and decrease need for recovery is scarce. Thus, the present study aims to describe the background, design and protocol of a cluster randomized controlled trial evaluating the effectiveness of an intervention to reduce need for recovery and improve work ability among industrial workers. Methods/Design: A two-year cluster randomized controlled design will be utilized, in which controls will also receive the intervention in year two. More than 400 workers from three companies in Denmark will be aimed to be cluster randomized into intervention and control groups with at least 200 workers (at least 9 work teams) in each group. An organizational resources audit and subsequent action planning workshop will be carried out to map the existing resources and act upon initiatives not functioning as intended. Workshops will be conducted to train leaders and health and safety representatives in supporting and facilitating the intervention activities. Group and individual level participatory visual mapping sessions will be carried out allowing team members to discuss current physical and psychosocial work demands and resources, and develop action plans to minimize strain and if possible, optimize the resources. At all levels, the intervention will be integrated into the existing organization of work schedules. An extensive process and effect evaluation on need for recovery and work ability will be carried out via questionnaires, observations, interviews and organizational data assessed at several time points throughout the intervention period. Discussion: This study primarily aims to develop, implement and evaluate an intervention based on the abovementioned features which may improve the work environment, available resources and health of industrial workers, and hence their need for recovery and work ability

Chronic Physiological Effects of Swim Training Interventions in Non-Elite Swimmers: A Systematic Review and Meta-Analysis

Background Swimming is a popular and potentially health-enhancing exercise, but has received less scientific attention compared with other exercise modes. Objective The objective of the study was to determine the chronic (long-term) effect of pool swim training on physiological outcomes in non-elite or non-competitive swimming participants
