ABSTRACT
OBJECTIVES: Employees of uniformed services (EoUS) were screened for cardiovascular risk factors. MATERIAL AND METHODS: A total of 1138 EoUS (age M±SD 49.9±6.0 years) and 263 controls (age M±SD 54.4±9.7 years) under the care of the cardiology clinic in Gdansk, Poland, were included in the study. Medical history and blood samples were collected, and a physical examination was performed. Ten-year cardiovascular risk of death was calculated using the systematic coronary risk evaluation (SCORE) risk algorithm for high-risk countries. RESULTS: Significantly higher values of mean systolic and mean diastolic blood pressure, mean total cholesterol level and mean BMI were recorded among the EoUS compared to controls (M±SD 141.7±11.6 mm Hg vs. 135.5±11.0 mm Hg, p < 0.001; 90.1±5.9 mm Hg vs. 84.5±6.8 mm Hg, p < 0.001; 6.01±0.76 mmol vs. 5.44±0.87 mmol, p < 0.001; 29.3±4.7 vs. 29.0±4.1, p < 0.001, respectively). Smoking cigarettes was most frequently reported by the youngest group (20-39 years old) - 47.7% and it was significantly higher in the entire EoUS group compared to control group (35.5% vs. 16.7%, p = 0.001). The occurrence of observed risk factors (blood pressure ≥140/90 mm Hg, total cholesterol concentration >5 mmol, smoking,) was significantly higher among EoUS compared to controls (92.1% vs. 57.8%, p < 0.001; 89.0% vs. 66.9%, p < 0.001; 35.5% vs. 16.7%, p < 0.001, respectively). In the male group, the mean calculated ten-year risk of fatal cardiovascular events, the percentage of high calculated risk, and very high risk were higher in the EoUS group compared to controls (M±SD 4.44±3.49 vs. 4.23±3.86, p = 0.001; 23.7% vs. 20.2%, p = 0.007; 7.4% vs. 6.5%, p = 0.03, respectively). CONCLUSIONS: The prevalence of all identified risk factors was found to be higher among employees of uniformed services when compared to the control group. The presence of these risk factors within the population of uniformed service employees results in a greater risk of mortality from cardiovascular diseases.

The aim of this study was to evaluate the effects of various supplemental greenhouse lighting systems, i.e., high-pressure sodium lamps and mixtures of red and blue light-emitting diodes, on the photochemical efficiency, anatomical leaf structure, and growth of the two pepper cultivars. The intensity levels of the photosynthetically active radiation were the same for both light treatments. In this study, the relative chlorophyll content was measured. Additionally, certain parameters of chlorophyll a fluorescence were measured under ambient light or after dark adaptation. The obtained results showed that the application of light-emitting diodes (LEDs) as supplemental lighting positively affected the anatomical leaf characteristics and plant growth. The leaves of both pepper cultivars were thicker and had larger palisade parenchyma cells under LED supplemental lighting compared to leaves grown under high-pressure sodium (HPS) lamps. Moreover, the mesophyll cells of seedlings grown under LEDs contained more chloroplasts than those growing under HPS lighting. The chlorophyll a fluorescence measurements of pepper seedlings grown under LEDs showed significant increases in photosynthetic apparatus performance index (PI) values compared to plants grown under HPS lamps; however, the values for this index were higher in cv. 'Aifos' as compared to cv. 'Palermo'. We recommend that supplemental lighting systems are applied with caution, as their performance appears to depend not only on the light spectrum but also on the cultivar.
ABSTRACT
A case of hypertensive patient with obstructive sleep apnea syndrome is presented. The third degree atrio-ventricular block was detected during diagnostic procedure and treatment of blood pressure in patient with obstructive sleep apnea. A heart pacemaker has been implanted. After this procedure the sleep apnea signs have not been detected.
