    Aim: To determine the frequency of chronic respiratory symptoms and ventilatory function in a group of vineyard workers. Results: Most of the vineyard workers believe that they are sufficiently informed about the health risks related to their work activities and the necessary measures needed for health protection. Also, most of them use the mandatory personal protective equipment, while almost all workers during their work, to a greater or lesser extent, were exposed to occupational respiratory hazards: dust, smoke, fumes, gases and pesticides. About 45% of subjects had one or more respiratory symptoms, and the most common symptoms were cough (40%), cough with phlegm (31.1%), as well as dyspnea and wheezing (22.2%). The frequency of chronic respiratory symptoms was higher in workers with more than 15 years of exposure, with a statistically significant difference in frequency of cough, cough with phlegm, and dyspnea. The risk of respiratory symptoms was about 3 times higher in active smokers and about 2 times higher in vineyard workers with exposure duration longer than 15 years. The mean values of all spirometric parameters were within the reference values, while lung function impairment of obstructive, restrictive and combined pattern was registered in about 20% of them. The mean values of spirometric parameters in vineyard workers with exposure duration longer than 15 years were lower than those with less than 15 years of experience, with a significant difference for small airways flow indices. Conclusion: The obtained results indicate the need to improve preventive measures.</jats:p>

    Introduction:Age and exposure to noxious particles and gases are considered as important risk factors for the development of COPD. Aim of the study:To assess the prevalence of COPD in a sample of retired persons from the Skopje region.Material and methods:We performed a cross-sectional study (prevalence study) in a sample of 392 randomly selected retired persons, 207 males and 185 females, aged 56 to 84 years. Study protocol included completion of a questionnaire and pre-and post-bronchodilator spirometry.Results:The prevalence of COPD in the whole sample was 8.7% (34/392),being non-significantly higher in men (9.1%) than in women (8.1%). The difference in COPD prevalence between smoking and non-smoking retired persons was within the borders of statistical significance (10.7% vs.7.5; P=0.084). The difference in COPD prevalence between retired persons exposed to vapors, gases, dusts, and fumes (VGDF) at their workplace during their active period and retired persons with no such exposure just missed statistical significance (9.5% vs.7.4%; P=0.073). COPD prevalence in the smoking retired persons occupationally exposed to VGDF during their active period was significantly higher than its prevalence in the smoking retired persons occupationally unexposed to VGDF during their active period (12.6% vs.8.2%; P=0.036). Conclusion: Our results confirm the role of age and exposure to noxious particles and gases in the COPD development.

    Introduction: Evidence of impact of COVID-19 infection on course of chronic obstructive pulmonary disease (COPD) is still limited. Aim: To assess clinical outcomes of moderate COVID-19 infection in patients with moderate COPD by comparison of disease control, i.e., the frequency and severity of symptoms, level of health status impairment, values of spirometrc parameters and exacerbation risk, registered at two points in time: 2020 and 2025. Material and methods: We performed a cross-sectional study including 74 patients with moderate COPD divided in two groups. The first group (COVID-19 group) included 37 COPD patients who had COVID-19 infection of moderate severity in 2020. The second group (non-COVID-19 group) included patients with COPD who did not have coronavirus disease in the period 2020-2025. The frequency and severity of symptoms and level of health impairment were assessed by COPD Assessment Test (CAT): lung function was assessed by spirometric measurements, and exacerbation risk was predicted by exacerbation rate registered in the previous year. Conclusion: Our findings indicated significant impact of the COVID-19 infection on symptoms, patient’s health and daily life, as well as on the lung function and exacerbation risk emphasizing a need of careful monitoring of these patients upon recovery from COVID-19 infection in order to minimize the impact of infection on COPD progression.

    PREVALENCE AND RISK FACTORS OF WORK-RELATED MUSCULOSKELETAL DISORDERS AMONG WORKERS IN HIGH-VOLTAGE TRANSMISSION LINE NETWORK AND SUBSTATIONS

    Introduction: There is a high risk of developing work-related musculoskeletal disorders (WMSDs) among workers in high-voltage transmission line network and substations. Most WMSDs are cumulative disorders resulting from repeated exposure to one or more harmful factors over a long period of time. Aim of the Study: The aim of this study is to determine the occurrence and frequency of symptoms of WMSDs among workers in high-voltage transmission line network and substations. Material and Methods: This cross-sectional study involves 100 workers from a high-voltage transmission line network and substations, all males aged 20 to 63, classified as electricians – group F06, electricians – group F07 and substation workers. The research methodology includes a standardized questionnaire “Symptoms Survey for Work-Related Musculoskeletal Disorders (WMSDs)”. The results obtained are statistically processed by descriptive and analytical methods. Results: The frequency of symptoms of WMSDs among workers from a high-voltage transmission line network and substations that lasted two or more days in the last year, and was caused by their work is 32% and it refers to pain or discomfort in any region. The most common localizations are determined on the lower back (14%), knee (11%) and shoulder (9%). No upper back pain was registered in any of the subjects. A significantly higher number of electricians reported that their working body position was combined compared to substation workers, and that they often had to reach further from their body compared to substation workers. On the other hand, a significantly higher number of substation workers declared that they do not reach beyond their body compared to electricians. There is no significant difference between substation workers and electricians in terms of performing repetitive movements. Conclusion: WMSDs are often regularly occurring among workers in high-voltage transmission line network and substations; therefore, it underlines the need for their early detection through preventive medical examinations and application of appropriate measures for protection of workers.
