Sight is the basic sense for drivers. Condition of the eye determines correct, comfortable and safe performance of the work as drivers. This article presents various factors influencing the sight condition. There are two groups of factors, external (environment, the kind and time of work, stress caused by work) and internal (systemic and local disorders). All these factors can reduce significantly visual functions, such as visual acuity, field of vision, color vision, strereoscopic vision, twilight vision and glare sensitivity. There are also presented actual requirements for drivers and causes of the car accidents in various age groups. Impairments in vision functions can be dangerous for both the driver and other road users. Med Pr 2013;64(3):419–425

Narząd wzroku jest dla kierowcy podstawowym narządem zmysłu. Jego stan warunkuje prawidłowe, komfortowe i bezpieczne wykonywanie tego rodzaju pracy. W artykule przedstawiono czynniki mogące wpływać na funkcje układu wzrokowego. Omówione zostały zarówno uwarunkowania zewnętrzne (środowisko, charakter i czas pracy, stres związany z jej wykonywaniem), jak i wewnętrzne (zaburzenia systemowe i miejscowe). Wszystkie wymienione czynniki mogą znacznie obniżać funkcje wzrokowe ważne dla kierowców, takie jak ostrość wzroku, pole widzenia, widzenie barwne, widzenie stereoskopowe i widzenie zmierzchowe oraz wrażliwość na olśnienie. Ponadto przedstawiono aktualne wymagania stawiane kierowcom różnych kategorii oraz przyczyny wypadków w różnych grupach wiekowych. Obniżenie funkcji wzrokowych może okazać się niebezpieczne zarówno dla kierowcy, jak i innych użytkowników dróg. Med. Pr. 2013;64(3):419–425

Monitoring of cardiovascular hemodynamic changes requires a very expensive and highly specialized equipment and skilled medical personnel. Up to the present time, an inexpensive, non-invasive and easy-to-use method which, like Doppler echocardiography, magnetic resonance angiography or radionuclide imaging, would assess hemodynamics of the cardiovascular system was not available. A method known as impedance cardiography (ICG) or thoracic electrical bioimpedance cardiography (TEBC) meets those criteria. It is non-invasive, which is of a particular advantage over the conventional methods that require catheterization. As a result, the patient is not at risk of possible complications and the procedure is less expensive and easier. Impedance cardiography, despite its non-invasive character, has not been so far extensively used for monitoring of hemodynamic parameters in hospitalized patients. Various authors report that attempts have been continued to compare the results from ICG and those obtained by other diagnostic methods. This paper presents the use of impedance cardiography in diagnosis of hypertension, cardiac insufficiency, differentiating the causes of acute dyspnea, as well as in assessing the effects of cardiac rehabilitation in patients with heart failure.

Impedance cardiography seems to be a very good, although underappreciated diagnostic method. What may distinguish it from among the many research methods is the fact that it enables non-invasive monitoring of cardiac output, stroke volume and systemic vascular resistance. Holter recording of the hemodynamic parameters makes it possible to study them not only in stationary (hospital, outpatient clinic) conditions, but also during household or professional activities, e.g., during road vehicle driving. Assessment of the trends of changes in the circulatory system of the employee at work makes it possible to judge whether the type of work performed by the worker is well tolerated – whether it is not too hard or too stressful. This is important, therefore, impedance cardiography can be extensively used in occupational medicine. Provision of preventive care to workers according to current standards requires, on the one hand, the use of the latest diagnostic methods while, on the other hand, the methods must be inexpensive, because otherwise the employer would not be able or willing to pay the associated costs. Impedance cardiography meets those criteria; however, few data is available in literature worldwide on the use of this method in the research on the impact of occupational work on cardiovascular responses of the employees. This work reports the use of impedance cardiography in studies on the various aspects of work environment.

The impact of physical activity on mental health is widely described in literature. Less attention is given to factors which may modify this correlation, except for gender. The aim of this study was to conduct a qualitative assessment of such papers relating to children and young people. Selected papers were evaluated with regard to additional factors related to family, school and neighborhood. Attention was drawn to the definitions of these variables, the methods of analysis, and the content of the discussion. The starting point for this study included 7 systematic reviews published in 2006–2018. A total of 161 full articles described in detail in those reviews, and representing different research patterns, were selected for qualitative analysis. They met the criteria for the type of publication, mental health outcome, the direction of association, and the age group. A supplementary section of this paper contains a review of Polish literature from the Polish Medical Bibliography, and an analysis of national studies and some more recent papers not included in the analyzed reviews. It was demonstrated that 33 papers analyzed environmental variables to a greater degree than the characteristics of the sample. Twenty-three papers containing the results of statistical analyses were considered to be of particular interest. Almost 50% of these included both the socio-economic position of the family and the characteristics of the neighborhood. However, only 1 featured stratification of the sample with regard to contextual environmental variables. The obtained results are of great practical importance. Firstly, development of the research into environmental moderators should be advocated. Secondly, the social context in which adolescents grow up should be taken into account when designing intervention programs. Int J Occup Med Environ Health. 2019;32(4):423–39

Road accidents are among the main fatalities worldwide and drowsy driving is a significant cause of road deaths where drivers are at fault. There are well known diseases which impair sensory and cognitive functions and can cause sleepiness during driving. Such diseases can be an important contraindication to driving because they may have an adverse effect on its safety. Thus, medical examinations for drivers should also be directed at identifying any possible conditions posing risks for driving safety. Occupational medicine specialists should look for symptoms of locomotor and sleep-related breathing disorders as these are medical conditions which could preclude a person from driving. In this case report, the authors describe a professional driver with chest deformity and present a pioneering attempt at assessing his medical fitness to drive. It is also explained why scoliosis can impair driving ability and how it should be diagnosed and treated. Finally, the authors describe how they used driving simulator tests as part of their diagnosis and suggest a relevant treatment regimen. Int J Occup Med Environ Health. 2019;32(5):735–45

Objectives Only a few studies have been undertaken to analyze the dietary habits of people with cardiovascular diseases. The aim of this study was to evaluate the dietary behaviors of working people who were hospitalized due to experiencing the first acute cardiovascular incident. Material and Methods In the study, the Functional Activity Questionnaire was used. The study was conducted in 2 groups. The first group included all the men hospitalized during 1 year (January–December 2009) in 2 clinics of cardiology, who were professionally active until the first myocardial infarction (MI). It comprised 243 men aged 26–70 years. The reference group consisted of 403 men, blue- and white-collar workers, aged 35–65 years. Results The body mass index of the MI patients was significantly higher (p = 0.006). The frequency of consumption of particular products in the MI group and in the reference group differed significantly for 11 of 21 products. The MI patients significantly less frequently reported the daily consumption of fruit, raw vegetables, cheese, vegetable oils and fish. In this group, the consumption of salty (p = 0.0226) or fatty (p < 0.0001) foods was significantly higher. It was shown that, after adjusting for age, education and the type of work, the daily consumption of fish, salads and cooked vegetables, as well as fruit and vegetable oils, significantly reduced the risk of myocardial infarction. An increased MI risk was, in turn, associated with obesity and preference for fatty foods. Conclusions The authors found that diet significantly modified the MI risk in the examined workers. This indicates that an important aspect of prevention activities among working people should involve education about proper dietary habits. Int J Occup Med Environ Health. 2019;32(6):853–63

Objectives The aim of the study was to establish whether the driver’s visual strategy may influence a driver’s behavior to avoid a crash in a high-risk situation. Any published papers on drivers’ visual strategies just before a crash were not found. Material and Methods Tests were performed using a high-tech driving bus simulator. Participants comprised 45 men drivers, aged 43.5±7.9 years old, seniority as a bus driver of 13.3±8.6 years. The tests were preceded by medical examinations: general, neurological and ophthalmological. Each participant drove the same city route for approximately 40 min (entire route – ER). In the final phase, a collision situation was simulated (a phantom car blocked the participant’s right of way). Driver’s visual strategy was analyzed using the FaceLab device with 2 cameras during ER and just before collision. The field-of-view covered by camera 1 was divided into 8 regions, by camera 2 into 10 regions. The distribution of gazes in regions was a criterion of visual strategy. Results Thirty-five drivers completed the simulated driving test, 14 escaped the collision, 21 crashed. These groups differed only in resting systolic blood pressure before the test. The analysis of covariance, after adjusting to this factor, indicated that during the ER visual strategy recorded by camera 1 did not differ between groups, in camera 2 the drivers in the crash group fixed their gaze more frequently (p = 0.049) in region 3 (close part of the road in front of the windshield). Just before the collision drivers who escaped the collision fixed their gaze significantly more often in region 6 (left side of the road) in camera 1 and in region 6 (in front of the windshield,) and region 10 (right side) in camera 2. Conclusions The visual strategy has an impact on the road safety. The analysis of visual strategies may be a useful tool for the training of drivers. Int J Occup Med Environ Health. 2019;32(2):161–74
