Background: Patient-reported outcome measures (PROMs) are validated and standardized tools that complement physician evaluations and guide treatment decisions. They are crucial for monitoring atopic dermatitis (AD) and chronic urticaria (CU) in clinical practice, but there are unmet needs and knowledge gaps regarding their use in clinical practice., Objecctive: We investigated the global real-world use of AD and CU PROMs in allergology and dermatology clinics as well as their associated local and regional networks., Methods: Across 72 specialized allergy and dermatology centers and their local and regional networks, 2,534 physicians in 73 countries completed a 53-item questionnaire on the use of PROMs for AD and CU., Results: Of 2,534 physicians, 1,308 were aware of PROMs. Of these, 14% and 15% used PROMs for AD and CU, respectively. Half of physicians who use PROMs do so only rarely or sometimes. Use of AD and CU PROM is associated with being female, younger, and a dermatologist. The Patient-Oriented Scoring Atopic Dermatitis Index and Urticaria Activity Score were the most common PROMs for AD and CU, respectively. Monitoring disease control and activity are the main drivers of the use of PROMs. Time constraints were the primary obstacle to using PROMs, followed by the impression that patients dislike PROMs. Users of AD and CU PROM would like training in selecting the proper PROM., Conclusions: Although PROMs offer several benefits, their use in routine practice is suboptimal, and physicians perceive barriers to their use. It is essential to attain higher levels of PROM implementation in accordance with national and international standards., (Copyright © 2024 The Authors. Published by Elsevier Inc.

Background: IgE-mediated food allergy (FA) is a global health concern with substantial individual and societal implications. While diverse intervention strategies have been researched, inconsistencies in reported outcomes limit evaluations of FA treatments. To streamline evaluations and promote consistent reporting, the Core Outcome Measures for Food Allergy (COMFA) initiative aimed to establish a Core Outcome Set (COS) for FA clinical trials and observational studies of interventions., Methods: The project involved a review of published clinical trials, trial protocols and qualitative literature. Outcomes found as a result of review were categorized and classified, informing a two-round online-modified Delphi process followed by hybrid consensus meeting to finalize the COS., Results: The literature review, taxonomy mapping and iterative discussions with diverse COMFA group yielded an initial list of 39 outcomes. The iterative online and in-person meetings reduced the list to 13 outcomes for voting in the formal Delphi process. One more outcome was added based on participant suggestions after the first Delphi round. A total of 778 participants from 52 countries participated, with 442 participating in both Delphi rounds. No outcome met a priori criteria for inclusion, and one was excluded as a result of the Delphi. Thirteen outcomes were brought to the hybrid consensus meeting as a result of Delphi and two outcomes, 'allergic symptoms' and 'quality of life' achieved consensus for inclusion as 'core' outcomes., Conclusion: In addition to the mandatory reporting of adverse events for FA clinical trials or observational studies of interventions, allergic symptoms and quality of life should be measured as core outcomes. Future work by COMFA will define how best to measure these core outcomes., (© 2024 The Authors. Allergy published by European Academy of Allergy and Clinical Immunology and John Wiley & Sons Ltd.)

Objectives: This study aims to present an overview of the formal recognition of COVID-19 as occupational disease (OD) or injury (OI) across Europe., Methods: A COVID-19 questionnaire was designed by a task group within COST-funded OMEGA-NET and sent to occupational health experts of 37 countries in WHO European region, with a last update in April 2022., Results: The questionnaire was filled out by experts from 35 countries. There are large differences between national systems regarding the recognition of OD and OI: 40% of countries have a list system, 57% a mixed system and one country an open system. In most countries, COVID-19 can be recognised as an OD (57%). In four countries, COVID-19 can be recognised as OI (11%) and in seven countries as either OD or OI (20%). In two countries, there is no recognition possible to date. Thirty-two countries (91%) recognise COVID-19 as OD/OI among healthcare workers. Working in certain jobs is considered proof of occupational exposure in 25 countries, contact with a colleague with confirmed infection in 19 countries, and contact with clients with confirmed infection in 21 countries. In most countries (57%), a positive PCR test is considered proof of disease. The three most common compensation benefits for COVID-19 as OI/OD are disability pension, treatment and rehabilitation. Long COVID is included in 26 countries., Conclusions: COVID-19 can be recognised as OD or OI in 94% of the European countries completing this survey, across different social security and embedded occupational health systems., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Introduction: Despite several studies assessing job demands and burnout in countries from the Southeast European (SEE) region, there is still a lack of data about the psychological impact of the pandemic on health workers (HWs)., Aims: The present study aimed to demonstrate and compare levels of burnout dimensions in HWs from SEE countries and to reveal the burnout-job demands/resources relationships in these workers during the pandemic., Materials and Methods: During the autumn of 2020, this online multicentric cross-sectional survey studied a large group ( N  = 4.621) of HWs working in SEE countries. The Maslach Burnout Inventory was used for the measurement of burnout dimensions. We analyzed the job demands by using the Hospital Experience Scale. Remuneration and relationships with superiors were measured using the Questionnaire sur les Ressources et Contraintes Professionnelles (English version)., Results: A series of ANOVA comparisons of means revealed the countries in which respondents showed higher mean values of emotional exhaustion (Bosnia and Herzegovina, Bulgaria, Croatia, Moldova, Montenegro, and North Macedonia) and the countries in which respondents showed lower mean values of this burnout dimension (Israel and Romania) (Welch F  = 17.98, p  < 0.001). We also found differences among HWs from different countries in job demands and job resources. The testing of hierarchical regression models, which have been controlled for certain confounding factors, clearly revealed that emotional exhaustion was predicted by job demands ( R 2  = 0.37) and job resources ( R 2  = 0.16)., Conclusion: Preventive measures for the improvement of mental health in HWs during the pandemic and beyond have to take into account the differences between countries regarding the country context and current scientific knowledge. A modified stress test should be implemented in hospitals regarding future shocks that might include new pandemics, terrorism, catastrophes, or border conflicts., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The author(s) declared that they were an editorial board member of Frontiers, at the time of submission. This had no impact on the peer review process and the final decision., (Copyright © 2023 Mijakoski, Atanasovska, Bislimovska, Brborović, Brborović, Cvjeanov Kezunović, Milošević, Minov, Önal, Pranjić, Rapas, Stoleski, Vangelova, Žaja, Bulat, Milovanović and Karadžinska-Bislimovska.)

Background: Food anaphylaxis is commonly elicited by unintentional ingestion of foods containing the allergen above the tolerance threshold level of the individual. While labeling the 14 main allergens used as ingredients in food products is mandatory in the EU, there is no legal definition of declaring potential contaminants. Precautionary allergen labeling such as "may contain traces of" is often used. However, this is unsatisfactory for consumers as they get no information if the contamination is below their personal threshold. In discussions with the food industry and technologists, it was suggested to use a voluntary declaration indicating that all declared contaminants are below a threshold of 0.5 mg protein per 100 g of food. This concentration is known to be below the threshold of most patients, and it can be technically guaranteed in most food production. However, it was also important to assess that in case of accidental ingestion of contaminants below this threshold by highly allergic patients, no fatal anaphylactic reaction could occur. Therefore, we performed a systematic review to assess whether a fatal reaction to 5mg of protein or less has been reported, assuming that a maximum portion size of 1kg of a processed food exceeds any meal and thus gives a sufficient safety margin., Methods: MEDLINE and EMBASE were searched until 24 January 2021 for provocation studies and case reports in which one of the 14 major food allergens was reported to elicit fatal or life-threatening anaphylactic reactions and assessed if these occurred below the ingestion of 5mg of protein. A Delphi process was performed to obtain an expert consensus on the results., Results: In the 210 studies included, in our search, no reports of fatal anaphylactic reactions reported below 5 mg protein ingested were identified. However, in provocation studies and case reports, severe reactions below 5 mg were reported for the following allergens: eggs, fish, lupin, milk, nuts, peanuts, soy, and sesame seeds., Conclusion: Based on the literature studied for this review, it can be stated that cross-contamination of the 14 major food allergens below 0.5 mg/100 g is likely not to endanger most food allergic patients when a standard portion of food is consumed. We propose to use the statement "this product contains the named allergens in the list of ingredients, it may contain traces of other contaminations (to be named, e.g. nut) at concentrations less than 0.5 mg per 100 g of this product" for a voluntary declaration on processed food packages. This level of avoidance of cross-contaminations can be achieved technically for most processed foods, and the statement would be a clear and helpful message to the consumers. However, it is clearly acknowledged that a voluntary declaration is only a first step to a legally binding solution. For this, further research on threshold levels is encouraged., (© 2021 The Authors. Allergy published by European Academy of Allergy and Clinical Immunology and John Wiley & Sons Ltd.)

We aimed to review the determinants of burnout onset in teachers. The study was conducted according to the PROSPERO protocol CRD42018105901, with a focus on teachers. We performed a literature search from 1990 to 2021 in three databases: MEDLINE, PsycINFO, and Embase. We included longitudinal studies assessing burnout as a dependent variable, with a sample of at least 50 teachers. We summarized studies by the types of determinant and used the MEVORECH tool for a risk of bias assessment (RBA). The quantitative synthesis focused on emotional exhaustion. We standardized the reported regression coefficients and their standard errors and plotted them using R software to distinguish between detrimental and protective determinants. A qualitative analysis of the included studies ( n = 33) identified 61 burnout determinants. The RBA showed that most studies had external and internal validity issues. Most studies implemented two waves (W) of data collection with 6-12 months between W1 and W2. Four types of determinants were summarized quantitatively, namely support, conflict, organizational context, and individual characteristics, based on six studies. This systematic review identified detrimental determinants of teacher exhaustion, including job satisfaction, work climate or pressure, teacher self-efficacy, neuroticism, perceived collective exhaustion, and classroom disruption. We recommend that authors consider using harmonized methods and protocols such as those developed in OMEGA-NET and other research consortia.

The management of occupational asthma (OA) may be influenced by several factors and removal from exposure is the main tertiary prevention approach, but it is not always feasible without personal and socioeconomic consequences. Reducing the delay between the onset of suggestive symptoms of OA and the diagnosis of OA is associated with a better prognosis. Workers' education to increase awareness to trigger agents and a medical surveillance program directed especially at at-risk workers could be helpful in reducing this latency time. An early identification of workers who develop rhinitis and conjunctivitis which often precede the onset of asthma symptoms could be important for an early identification of OA. This is particularly important for cases of asthma caused by high-molecular-weight sensitizers and in the early years of employment. The availability of financial support and compensation measures for workers with OA may influence the latency time before diagnosis and, consequently, may influence the OA outcomes. In conclusion, there is a need for high-quality cohort studies that will increase knowledge about risk factor that may influence the timing of diagnosis of OA. This knowledge will be useful for implementation of future surveillance and screening programs in workplaces., (© The Author(s) 2021.

We aimed to review occupational burnout predictors, considering their type, effect size and role (protective versus harmful), and the overall evidence of their importance. MEDLINE, PsycINFO, and Embase were searched from January 1990 to August 2018 for longitudinal studies examining any predictor of occupational burnout among workers. We arranged predictors in four families and 13 subfamilies of homogenous constructs. The plots of z-scores per predictor type enabled graphical discrimination of the effects. The vote-counting and binomial test enabled discrimination of the effect direction. The size of the effect was estimated using Cohen's formula. The risk of bias and the overall evidence were assessed using the MEVORECH and GRADE methods, respectively. Eighty-five studies examining 261 predictors were included. We found a moderate quality of evidence for the harmful effects of the job demands subfamily (six predictors), and negative job attitudes, with effect sizes from small to medium. We also found a moderate quality of evidence for the protective effect of adaptive coping (small effect sizes) and leisure (small to medium effect sizes). Preventive interventions for occupational burnout might benefit from intervening on the established predictors regarding reducing job demands and negative job attitudes and promoting adaptive coping and leisure.

Objective A consensual definition of occupational burnout is currently lacking. We aimed to harmonize the definition of occupational burnout as a health outcome in medical research and reach a consensus on this definition within the Network on the Coordination and Harmonisation of European Occupational Cohorts (OMEGA-NET). Methods First, we performed a systematic review in MEDLINE, PsycINFO and Embase (January 1990 to August 2018) and a semantic analysis of the available definitions. We used the definitions of burnout and burnout-related concepts from the Systematized Nomenclature of Medicine Clinical Terms (SNOMED-CT) to formulate a consistent harmonized definition of the concept. Second, we sought to obtain the Delphi consensus on the proposed definition. Results We identified 88 unique definitions of burnout and assigned each of them to 1 of the 11 original definitions. The semantic analysis yielded a first proposal, further reformulated according to SNOMED-CT and the panelists` comments as follows: "In a worker, occupational burnout or occupational physical AND emotional exhaustion state is an exhaustion due to prolonged exposure to work-related problems". A panel of 50 experts (researchers and healthcare professionals with an interest for occupational burnout) reached consensus on this proposal at the second round of the Delphi, with 82% of experts agreeing on it. Conclusion This study resulted in a harmonized definition of occupational burnout approved by experts from 29 countries within OMEGA-NET. Future research should address the reproducibility of the Delphi consensus in a larger panel of experts, representing more countries, and examine the practicability of the definition.

IgE-mediated food allergies are caused by adverse immunologic responses to food proteins. Allergic reactions may present locally in different tissues such as skin, gastrointestinal and respiratory tract and may result is systemic life-threatening reactions. During the last decades, the prevalence of food allergies has significantly increased throughout the world, and considerable efforts have been made to develop curative therapies. Food allergen immunotherapy is a promising therapeutic approach for food allergies that is based on the administration of increasing doses of culprit food extracts, or purified, and sometime modified food allergens. Different routes of administration for food allergen immunotherapy including oral, sublingual, epicutaneous and subcutaneous regimens are being evaluated. Although a wealth of data from clinical food allergen immunotherapy trials has been obtained, a lack of consistency in assessed clinical and immunological outcome measures presents a major hurdle for evaluating these new treatments. Coordinated efforts are needed to establish standardized outcome measures to be applied in food allergy immunotherapy studies, allowing for better harmonization of data and setting the standards for the future research. Several immunological parameters have been measured in food allergen immunotherapy, including allergen-specific immunoglobulin levels, basophil activation, cytokines, and other soluble biomarkers, T cell and B cell responses and skin prick tests. In this review we discuss different immunological parameters and assess their applicability as potential outcome measures for food allergen immunotherapy that may be included in such a standardized set of outcome measures., (Copyright © 2020 Schoos, Bullens, Chawes, Costa, De Vlieger, DunnGalvin, Epstein, Garssen, Hilger, Knipping, Kuehn, Mijakoski, Munblit, Nekliudov, Ozdemir, Patient, Peroni, Stoleski, Stylianou, Tukalj, Verhoeckx, Zidarn and van de Veen.)

Objective: Food allergy is a common condition that can have a significant impact on the quality of life of affected individuals and their caregivers. Recent years have witnessed an increased effort to identify new treatments for food allergy. Here, we review the need to identify core outcomes for measurement in clinical trials of food allergy treatments., Data Sources: We reviewed the literature regarding core outcome set development, the important role that these play in prioritizing patient-relevant outcomes, and the potential for core outcomes to accelerate the path to product marketing by allowing prompt and reliable evidence synthesis after trial publication., Study Selections: We reviewed recent clinical trials of food allergy treatments to understand which outcomes have previously been measured, and also reviewed available core outcome set initiatives for other allergic conditions to understand which other outcomes might be explored in future trials., Results: Clinical trials of food allergy treatments have largely focused on outcomes that are relevant to investigators and commercial investors, especially the threshold of reactivity and immunologic changes. Future trials should consider addressing patient-important outcomes and should report the experiences of both adult and child participants and their caregivers., Conclusion: There is a pressing need for core outcome set development for food allergy treatment trials., (Copyright © 2020.

Background: The failure of mucus clearance in bronchiectasis can be improved by chest physiotherapy or/and mucoactive agents., Aim: To assess the effects of long-term use of carbocysteine on frequency and duration of exacerbations in patients with bronchiectasis., Methods: We performed an observational, non-randomized, open study (a real-life study) including 64 patients with bronchiectasis divided into two groups, examined group (EG) and control group (CG). All participants were treated with appropriate treatment for the stable disease, but in the study, subjects of EG two capsules 375 mg carbocysteine three times a day was added over three months. Daily diary cards realised collection of data regarding the occurrence and duration of exacerbation in all study subjects., Results: Over the study period 43 exacerbations were documented, 17 in the EG and 26 in the CG, 10 (23.4%) of which required hospital treatment (four in the EG [23.5%] and six in the CG [23.1%]). A mean number of exacerbations over the study period was significantly lower in the EG (0.5 ± 0.1) as compared to their mean number in the CG (0.8 ± 0.2) (P = 0.0000). Mean duration of exacerbations expressed in days needed for complete resolution of symptoms or return of the symptoms to their baseline severity in the EG was significantly shorter than the mean duration of exacerbations in the CG (10.1 ± 2.6 vs 12.8 ± 2.1; P = 0.0000). The frequency of adverse effects, i.e. mild gastrointestinal manifestations and headache which did not require discontinuation of the treatment, in the EG during the study period was 15.6%., Conclusion: Our findings indicated positive effects of carbocysteine regarding the frequency and duration of exacerbations, as well as its good tolerability in the patients with bronchiectasis., (Copyright: © 2019 Jordan Minov, Sasho Stoleski, Tatjana Petrova, Kristin Vasilevska, Dragan Mijakoski, Jovanka Karadzinska-Bislimovska.)

Aim: To evaluate the prevalence of chronic respiratory symptoms, lung function impairment, and chronic obstructive respiratory diseases in dairy farmers. Our objective is to then examine their relation to exposure duration and to explore the usefulness of job exposure matrices as tools for exposure assessment, and predictors for respiratory health impairment., Methods: A cross-sectional study was performed, including 83 dairy farmers (mean age: 52.6 ± 8.7 years; mean exposure duration: 23.7 ± 7.6 years) and 80 office workers as a control group (mean age: 52.7 ± 8.2 years) matched for age, smoking habits, and socioeconomic status. Methods of evaluating examined subjects included a questionnaire on respiratory symptoms in the last 12 months, spirometry and histamine challenge, as well as the use of job exposure matrices (JEM)., Results: Dairy farmers had a significantly higher prevalence of cough (38.5), phlegm (27.7%), and wheezing (21.7%), than controls (p < 0.05). All mean baseline spirometric parameters were lower in dairy farmers compared to the controls, but statistical significance was confirmed only for MEF25, MEF50, and MEF75% (p = 0.010, p = 0.001, and p = 0.004, respectively). The prevalence of bronchial hyperresponsiveness, asthma, and chronic obstructive pulmonary disease was higher in dairy farmers but without statistical significance. JEM were useful tools for exposure assessment and predictors of factors for asthma and COPD development., Conclusion: The results suggest that occupational exposure among crop farmers is associated with a higher prevalence of respiratory symptoms, lung function impairment, and a higher prevalence of chronic respiratory diseases. JEM showed good potential for farming exposure evaluation and promoted their applicability within the diagnostic algorithm focused on respiratory health assessment., (Copyright: © 2019 Saso Stoleski, Jordan Minov, Jovanka Karadzinska-Bislimovska, Dragan Mijakoski, Aneta Atanasovska, Dragana Bislimovska.)

Background: Bacterial infections are involved in more than a half of the exacerbations of chronic obstructive pulmonary disease (COPD)., Aim: To evaluate the efficacy and safety of moxifloxacin in the outpatient treatment of moderate exacerbations of bacterial origin in the COPD patients., Methods: We performed a prospective, observational study including 64 COPD patients with moderate exacerbation of bacterial origin empirically treated with moxifloxacin. In 31 of them, moxifloxacin was used as an initial antibiotic (Group 1), whereas in 33 of them moxifloxacin was used after treatment failure with another antibiotic (Group 2). All patients have treated 7 days with moxifloxacin 400 mg once daily per os, and they were followed up for 20 days, with an intermediate visit at 3, 5 and 7 days at which the duration of symptoms and the side effects of the drug were evaluated., Results: We registered high clinical success rate, i.e. the complete resolution of the symptoms or their return to the baseline severity, similar in both groups (84.3% in all study subjects, 83.9% in the Group 1 and 84.8% in the Group 2). The mean time to complete resolution of the cardinal symptoms or their return to the baseline severity was 5.2 ± 1.1 days. Also, the mean time to complete resolution of the certain cardinal symptoms (increased dyspnea, increased sputum volume and increased sputum purulence) or their return to the baseline severity is given 4.9, 4.7 and 4.2 days, respectively. The incidence of adverse effects during the treatment with moxifloxacin in all study subjects was 10.9%, 9.6% in Group 1 and 12.1% in Group 2. There was no serious adverse effect that required discontinuation of the treatment. Relapse during a 20 days follow-up period was registered in 7.4% of the all study subjects with complete resolution of the cardinal symptoms or their return to the baseline severity, i.e. in two patients from both Group 1 and Group 2 (7.6% and 7.1%, respectively). 4., Conclusion: Our findings suggest high efficacy and good tolerability of moxifloxacin in the treatment of moderate COPD exacerbations of bacterial origin.

Aim: The purpose of the paper was to assess job demands, burnout, and teamwork in healthcare professionals (HPs) working in a general hospital that was analysed at two points in time with a time lag of three years., Methods: Time 1 respondents (N = 325) were HPs who participated during the first wave of data collection (2011). Time 2 respondents (N = 197) were HPs from the same hospital who responded at Time 2 (2014). Job demands, burnout, and teamwork were measured with Hospital Experience Scale, Maslach Burnout Inventory, and Hospital Survey on Patient Safety Culture, respectively., Results: Significantly higher scores of emotional exhaustion (21.03 vs. 15.37, t = 5.1, p < 0.001), depersonalization (4.48 vs. 2.75, t = 3.8, p < 0.001), as well as organizational (2.51 vs. 2.34, t = 2.38, p = 0.017), emotional (2.46 vs. 2.25, t = 3.68, p < 0.001), and cognitive (2.82 vs. 2.64, t = 2.68, p = 0.008) job demands were found at Time 2. Teamwork levels were similar at both points in time (Time 1 = 3.84 vs. Time 2 = 3.84, t = 0.043, p = 0.97)., Conclusion: Actual longitudinal study revealed significantly higher mean values of emotional exhaustion and depersonalization in 2014 that could be explained by significantly increased job demands between analysed points in time.

Objective: To assess the mean serum eosinophil cationic protein (s-ECP) concentrations among crop and dairy farmers and office controls, and further examine its relation to exposure duration, smoking habit, as well as presence or absence of asthma., Methods: A cross-sectional survey was performed including examined group (EG), composed by agricultural workers (87 crop - EG1 and 83 dairy farmers - EG2), and control group (CG) composed by 80 office workers within the same enterprise. We have used a questionnaire to record the chronic respiratory symptoms, detailed work history, specific farming activities and tasks performed and smoking history. Evaluation of examined subjects also included lung function tests, diagnosis of asthma, and measurement of s-ECP as a marker of inflammation., Results: The main finding of the present study is that s-ECP concentrations were raised in subjects with asthma independent of the smoking habit. The mean s-ECP concentrations were higher in subjects of EG1 and EG2 compared with those in CG, but without reaching statistical significance. Mean s-ECP concentrations were significantly higher among subjects in EG1 exposed more than 20 years, while mean s-ECP concentrations were non-significantly higher in subjects of EG2 exposed more than 20 years, compared to those exposed less than 20 years. Mean s-ECP concentrations were higher among smokers within all three groups, but without reaching statistical significance between smokers and non-smokers. Mean s-ECP concentrations were significantly higher in subjects with asthma within EG1 (P = 0.049) and EG2 (P = 0.040), but also within those in CG (P = 0.046)., Conclusion: Data obtained suggest that airway inflammation is present in farmers with asthma, and s-ECP is an important biomarker in means of reflecting disease severity and prognosis among exposed workers.

Background: 1,3/1,6-β-glucans are recognised as immunomodulators in human and veterinary medicine for over 50 years., Aim: To assess the effects of pleuran (1,3/1,6-β-glucan from Pleurotus ostreatus ) on incidence and duration of bacterial exacerbations in patients with COPD., Methods: We performed an observational, non-randomized, open-label study including 32 COPD patients (Group D) in whom besides the recommended chronic treatment for the stable disease were administered supplement combination containing pleuran 100 mg, vitamin C 60 mg and zinc 5 mg once daily over a three month-period (Group 1). Also, an equal number of Group D COPD patients who besides the recommended treatment for stable disease received the supplement combination containing vitamin C 60 mg and zinc 5 mg once daily, matched to the study subjects of the Group 1 by sex and age served as control (Group 2)., Results: Over the study period 57 exacerbations (24 in the Group 1 and 33 in the Group 2) were documented. A mean number of exacerbations over the study period was significantly lower in the Group1 (0.7 ± 0.4) as compared to their mean number in the Group 2 (1.0 ± 0.6) (P = 0.0218). Furthermore, a mean duration of exacerbations expressed in days needed for cure or clinical improvement (i.e. complete resolution of symptoms or return of the symptoms to their baseline severity) in the Group 1 (6.7 ± 0.8 days) was significantly shorter than the mean duration of exacerbations in the Group 2 (7.4 ± 1.3 days) (P = 0.0118). There was not reported any adverse effect during the study period by study subjects from both examined groups., Conclusion: Our findings indicated that pleuran might impact the incidence and duration of bacterial exacerbations in patients with COPD. There is a need for further studies for more precise determination of the influence of pleuran on the course of COPD.

Aim: To assess the mean serum C-reactive protein concentrations among farmers and office controls, and further examined its relation to exposure duration, smoking habit, as well as presence or absence of COPD., Methods: A cross-sectional survey was performed including examined group (EG), composed of agricultural workers (87 crop - EG1 and 83 dairy farmers - EG2), and control group (CG) composed by 80 office workers. Evaluation of subjects included a questionnaire on chronic respiratory symptoms, lung function tests, COPD diagnostics, and measurement of CRP serum concentrations., Results: Serum CRP concentrations were raised in stable COPD patients independent of smoking habit or exposure duration. The mean CRP serum concentrations were higher in the subjects of EG1 and EG2 compared with those in CG, but without statistical significance. This count for mean CRP serum concentrations in subjects of EG1 and EG2 exposed more than 20 years and for those in smokers in all three groups as well. The mean CRP serum concentrations were significantly higher in subjects with COPD within EG1 (P=0.049) and EG2 (P=0.040), while those in CG were not., Conclusion: Data obtained suggest that systemic inflammation is present in farmers with COPD and CRP is an important biomarker in COPD in means of reflecting disease severity and prognosis of exposed farmers.

There is evidence that coexisting bronchiectasis (BE) in patients with chronic obstructive pulmonary disease (COPD) aggravates the course of the disease. In this study, we aimed to evaluate the frequency and severity of bacterial exacerbations in COPD patients with BE. The frequency and duration of bacterial exacerbations treated in a 12-month period, as well as the duration of the exacerbation-free interval, were evaluated in 54 patients with COPD (Group D) who were diagnosed and assessed according to official recommendations. In 27 patients, BE was diagnosed by high-resolution computed tomography (HRCT), whereas an equal number of COPD patients who were confirmed negative for BE by HRCT, served as controls. We found a significantly higher mean number of exacerbations in a 12-month period in COPD patients with BE (2.9 ± 0.5), as compared to their mean number in controls (2.5 ± 0.3) (p = 0.0008). The mean duration of exacerbation, i.e. the mean number of days elapsed before complete resolution of the symptoms or their return to the baseline severity, was significantly longer in COPD patients with BE as compared to their mean duration in controls (6.9 ± 1.8 vs. 5.7 ± 1.4; p = 0.0085). In addition, the mean exacerbation-free interval expressed in days, in patients with COPD with BE, was significantly shorter than in COPD patients in whom BE were excluded (56.4 ± 17.1 vs. 67.2 ± 14.3; p = 0.0149). Overall, our findings indicate that coexisting BE in COPD patients may lead to more frequent exacerbations with a longer duration.

Objectives: Within an underlying health-impairing process, work stressors exhaust employees' mental and physical resources and lead to exhaustion/burnout and to health problems, with health-impairing behaviors being one of the potential mechanisms, linking burnout to ill health. The study aims to explore the associations between burnout and fast food consumption, exercise, alcohol consumption and painkiller use in a multinational sample of 2623 doctors, nurses and residents from Greece, Portugal, Bulgaria, Romania, Turkey, Croatia and Macedonia, adopting a cross-national approach., Methods: Data are part of the international cross-sectional quantitative ORCAB survey. The measures included the Maslach Burnout Inventory and the Health Behaviors Questionnaire., Results: Burnout was significantly positively associated with higher fast food consumption, infrequent exercise, higher alcohol consumption and more frequent painkiller use in the full sample, and these associations remained significant after the inclusion of individual differences factors and country of residence. Cross-national comparisons showed significant differences in burnout and health behaviors, and some differences in the statistical significance and magnitude (but not the direction) of the associations between them. Health professionals from Turkey, Greece and Bulgaria reported the most unfavorable experiences., Conclusions: Burnout and risk health behaviors among health professionals are important both in the context of health professionals' health and well-being and as factors contributing to medical errors and inadequate patient safety. Organizational interventions should incorporate early identification of such behaviors together with programs promoting health and aimed at the reduction of burnout and work-related stress.

Aim: The purpose of the actual study was to evaluate the relationship between the formation of anti-inflammatory cytokine IL10 and several indicators of moderate and severe preeclampsia in the third trimester of pregnancy., Material and Methods: Examination of the indicators of preeclampsia and maternal IL10 levels was conducted in 50 women with pregnancies complicated by varying degrees of preeclampsia in the third trimester of gestation as well as in 50 normotensive patients, hospitalized at the University Clinic of Gynecology and Obstetrics, Skopje, Republic of Macedonia. The levels of IL10 were determined with a commercial test developed by Orgenium Laboratories (Finland), using reagents from AviBion ELISA research kits. Patients with preeclampsia were categorized into moderate and severe preeclampsia group according to the degree of preeclampsia. Logistic regression analysis was used to determine the predictive value of different parameters for the occurrence of severe preeclampsia. Odds ratios and 95% Confidence Intervals were calculated in order to quantify independent associations., Results: The regression analysis detected systolic blood pressure (160 mmHg or higher), diastolic blood pressure (100 mmHg or higher), persistent proteinuria in pregnancy, serum LDH concentration (450 U/L or higher) and reduced serum concentrations of IL10 as significant predictors of severe preeclampsia in pregnant women after adjusting for age., Conclusion: The findings of significantly lower serum IL10 concentrations in patients with severe preeclampsia in comparison with respective concentrations in patients with moderate preeclampsia can be considered as major pathognomonic laboratory sign of severe preeclampsia.

Background: Teaching is considered a highly stressful occupation, with work-related stress levels among teachers being among the highest compared to other professions. Unfortunately there are very few studies regarding the levels of work-related stress among teachers in the Republic of Macedonia., Aim: To identify the level of self-perceived work-related stress among teachers in elementary schools and its relationship to gender, age, position in the workplace, the level of education and working experience., Material and Methods: We performed a descriptive-analytical model of a cross-sectional study that involved 300 teachers employed in nine elementary schools. Evaluation of examined subjects included completion of a specially designed questionnaire., Results: We found that the majority of interviewed teachers perceive their work-related stress as moderate. The level of work-related stress was significantly high related to the gender, age, position in workplace, as well as working experience (p < 0.01), while it was significant related to level of education (p < 0.05). Significantly greater number of lower-grade teachers perceives the workplace as extremely stressful as compared to the upper-grade teachers (18.5% vs. 5.45%), while the same is true for female respondents as compared to the male ones (15.38% vs. 3.8%). In addition, our results show that teachers with university education significantly more often associate their workplace with stronger stress than their colleagues with high education (13.48% vs. 9.4%). We also found that there is no significant difference of stress levels between new and more experienced teachers., Conclusion: Our findings confirm that the majority of interviewed teachers perceived their work-related stress as high or very high. In terms of the relationship between the level of teachers' stress and certain demographic and job characteristics, according to our results, the level of work-related stress has shown significantly high relation to gender, age, levels of grades taught as well as working experience, and significant relation to the level of education.

Background: Burnout results from a prolonged response to chronic emotional and interpersonal workplace stressors. The focus of research has been widened to job engagement., Aim: Purpose of the study was to examine associations between burnout, job engagement, work demands, and organisational culture (OC) and to demonstrate differences between physicians and nurses working in general hospital in Skopje, Republic of Macedonia., Material and Methods: Maslach Burnout Inventory and Utrecht Work Engagement Scale were used for assessment of burnout and job engagement. Work demands and OC were measured with Hospital Experience Scale and Competing Values Framework, respectively., Results: Higher scores of dedication, hierarchy OC, and organizational work demands were found in physicians. Nurses demonstrated higher scores of clan OC. Burnout negatively correlated with clan and market OC in physicians and nurses. Job engagement positively correlated with clan and market OC in nurses. Different work demands were related to different dimensions of burnout and/or job engagement. Our findings support job demands-resources (JD-R) model (Demerouti and Bakker)., Conclusions: Data obtained can be used in implementation of specific organizational interventions in the hospital setting. Providing adequate JD-R interaction can lead to prevention of burnout in health professionals (HPs) and contribute positively to better job engagement in HPs and higher quality of patient care.

Introduction: COPD Assessment Test (CAT) is an 8-items questionnaire for assessment of health status in patients with chronic obstructive pulmonary disease (COPD)., Objective: To evaluate the course of CAT scores during bacterial exacerbations of COPD treated in outpatient setting., Methods: We performed an observational, prospective study including 81 outpatients (57 males and 24 females, aged 43 to 74 years) with bacterial exacerbation of COPD. All participants completed CAT at initial visit (i.e. at the time of diagnosis of exacerbation and beginning of its treatment), 10 and 30 days after initial visit. Mean scores of each item, as well as the overall mean score, at these time points were compared., Results: The mean scores for each CAT question at initial visit varied from 2.6 to 3.5, whereas the mean scores for each CAT question 10 days after initial visit varied from 1.7 to 2.6. We registered significant reduction of the mean overall CAT score 10 days after initial visit as compared to its value at initial visit of 6.9 ± 2.7 points (16.8 vs 23.7; P < 0.001). The mean scores for each CAT question 30 days after initial visit varied from 1.3 to 2.4. We registered reduction of mean overall CAT score 30 days after initial visit as compared to its score 10 days after initial visit of 2.9 ± 1.2 points (13.9 vs 16.8; P < 0.005). The mean overall CAT score 30 days after initial visit was reduced for 9.8 ± 4.5 points as compared to its value at initial visit (13.9 vs 23.7; P < 0.001)., Conclusion: We found significant improvement in the patient's health status during recovery from exacerbation as compared to their health status at the time of exacerbation confirming the CAT as an effective tool to measure health status in patients with COPD.

Introduction: Work-related chronic obstructive pulmonary disease (COPD) represents a considerable part of the disease burden globally., Objective: To assess the COPD prevalence and characteristics in never-smoking dairy farmers., Materials and Methodology: We have conducted a cross-sectional study with 75 male dairy farmers aged 26 to 59 years, and compared them with equivalent number of male office workers similar by age, and duration of employment. Data on chronic respiratory symptoms, job history and daily activities were obtained by questionnaire. Lung functional testing of the examined subjects included baseline spirometry, and bronchodilator reversibility measurement., Results: Dairy farmers showed higher prevalence of overall respiratory symptoms, but significant difference was noticed for cough, phlegm, and dyspnea. Dairy farmers had more prevalent work-related respiratory symptoms, being significant for overall symptoms, cough, and phlegm. The mean baseline values of spirometric parameters were lower in dairy farmers, but significance was reported for FEV1/FVC%, MEF50, MEF75, and MEF25-75. Dairy farmers had significantly higher COPD prevalence than office controls (10.7% vs 2.7%, P = 0,049). Dairy farmers and office controls showed significant association between COPD and age over 45 years. Dairy farmers had a significant association between COPD and employment duration of over 20 years (P = 0.023), but also between COPD and work-related chronic respiratory symptoms (P = 0.041)., Conclusion: The study findings favor the cause-effect association between job exposure to respiratory hazards, and development of persistent airway obstruction among dairy farmers.

Background: Burnout syndrome develops in health professionals (HPs) as a result of exposure to chronic emotional and interpersonal workplace stressors. Research demonstrates the links between burnout, work demands, and job satisfaction in hospital HPs., Aims: To examine the associations between burnout, work demands and job satisfaction, and to demonstrate the mediation effect of emotional exhaustion on the relationship between work demands and job satisfaction in surgery clinic HPs., Methods: Maslach Burnout Inventory was used for assessment of burnout. Work demands and job satisfaction were measured with Hospital Experience Scale and Job Satisfaction Survey, respectively. In order to examine the role of emotional exhaustion, depersonalization, and work demands, controlling for age, hospital tenure, and unit tenure, a hierarchical multiple regression models were tested for each job satisfaction factor., Results: Job satisfaction was negatively predicted by emotional exhaustion. Certain types of work demands negatively predicted different factors of job satisfaction. Emotional exhaustion was a significant partial mediator of the relationship between work demands and job satisfaction., Conclusions: Adequate management of work demands, particularly excessive workload, time pressure, and lack of staff can lead to prevention of burnout and reduced job satisfaction in surgery clinic HPs, and contribute to better quality of patient care.

Introduction: Job exposure in agricultural workers often leads to respiratory impairment., Aim: To assess the influence of exposure duration and smoking on chronic respiratory symptoms and ventilatory capacity in agricultural workers., Methods: A cross-sectional study covered 75 agricultural workers, compared with an equal number of office workers matched by age, exposure duration and smoking status. Standardized questionnaire was used to obtain data on chronic respiratory symptoms, job and smoking history. Lung functional testing was performed by spirometry., Results: The prevalence of respiratory symptoms was higher in agricultural workers, with significant difference for cough (P = 0.034), and dyspnea (P = 0.028). Chronic respiratory symptoms among agricultural workers were significantly associated with duration of exposure (P < 0.05) and daily smoking (P < 0.01), as well as with daily smoking in controls (P < 0.01). The average values of spirometric parameters in exposed workers were significantly different for MEF50 (P = 0.002), MEF75 (P = 0.000), and MEF25-75 (P = 0.049). Obstructive changes in small airways in exposed workers were strongly related to exposure duration (P < 0.05) and smoking (P < 0.01). Agricultural workers with job exposure more than 15 years had more expressed adverse respiratory symptoms and lung function decline., Conclusion: The results confirmed the influence of agricultural exposure and daily smoking on chronic respiratory symptoms and airflow limitation, primarily targeting the small airways.

Background: Few studies have examined teamwork as mediator and moderator of work demands-burnout and job engagement-job satisfaction relationships in healthcare workers (HCWs) in South-East Europe., Aim: To assess mediation and moderation effect of teamwork on the relationship between independent (work demands or job engagement) and dependent (burnout or job satisfaction) variables., Methods: Work demands, burnout, job engagement, and job satisfaction were measured with Hospital Experience Scale, Maslach Burnout Inventory, Utrecht Work Engagement Scale, and Job Satisfaction Survey, respectively. Hospital Survey on Patient Safety Culture was used for assessment of teamwork. In order to examine role of teamwork as a mediating variable we fit series of regression models for burnout and job satisfaction. We also fit regression models predicting outcome (burnout or job satisfaction) from predictor (work demands or job engagement) and moderator (teamwork) variable., Results: Teamwork was partial mediator of work demands-burnout relationship and full mediator of job engagement-job satisfaction relationship. We found that only job engagement-job satisfaction relationship was moderated by teamwork., Conclusions: Occupational health services should target detection of burnout in HCWs and implementation of organizational interventions in hospitals, taking into account findings that teamwork predicted reduced burnout and higher job satisfaction.
