Background:  Occupational factors, working conditions, age, gender, exercise, acquired habits, and stress affect a person's sleep quality. The aim of this study was to investigate sleep quality, work stress, and related factors among office workers in a hospital., Methods:  This cross-sectional study was conducted with office workers actively working in a hospital. A questionnaire consisting of a sociodemographic data form, the Pittsburgh Sleep Quality Index (PSQI), and Swedish Workload-Control-Support Scale were used to assess the participants.    Results: The mean of PSQI score was 4.32±2.40 and 27.2% of the participants had poor sleep quality. In the multivariate backward stepwise logistic regression analysis, it was found that shift workers were 1.73 times (95% CI: 1.02-2.91) more likely to have poor sleep quality, and a one-unit increase in work stress score increased the risk of having poor sleep quality by 2.59 times (95% CI: 1.37-4.87). An increase in age was found to decrease the risk of poor sleep quality in workers (OR =0.95; 95% CI: 0.93-0.98)., Conclusion:  This study suggests that reducing workload and increasing work control as well as enhancing social support will be effective in preventing sleep disturbances. It is important, however, in terms of providing guidance for hospital employees in planning future measures to improve working conditions.

Objectives. We aimed to determine the prevalence of self-reported symptoms of carpal tunnel syndrome ( CTS) and associated risk factors among hospital office workers. Methods . This cross-sectional study was carried out between May and August 2021 with office workers actively working in a hospital in Izmir, Turkey. The Boston carpal tunnel syndrome questionnaire was used to evaluate the severity of self-reported CTS symptoms and their effect on the functional status of the participants. Results . The study included 151 people, 68.2% of whom were women. CTS symptoms were reported by 74.1% of the participants, the majority of whom (73.2%) were women. These reported symptoms were mild in 43%, moderate in 24.5%, severe in 5.3% and very severe in 1.3%. Significant differences were found between those with and without CTS symptoms regarding age, body mass index, previous diagnosis of CTS, daily work hours, using a wrist-supported mousepad and perceived workload ( p  < 0.05). Conclusion . CTS symptoms of office workers in the hospital were associated with occupational characteristics as well as individual factors. These risk factors should be taken into account while planning for future preventive and interventional measures in workplaces.

Blood cells are used as the most sensitive marker to determine the effects and intensity of ionizing radiation. This descriptive study aimed to evaluate the effect of radiation exposure on hematological parameters in healthcare workers who were exposed to radiation in a university hospital between May and June 2021. A total of 339 participants were included, of which 169 (49.9%) were radiation workers and 170 (50.1%) were in the control group. A decrease was observed in white blood cell and neutrophil counts in those exposed to ionizing radiation for less than 10 years; however, white blood cell, neutrophil, hemoglobin levels decreased, and red cell distribution width (RDW) levels increased in those exposed to ionizing radiation for 10 years or more ( p  < 0.005). A statistically significant increase was observed in the RDW and lymphocyte levels as the years of work experience in the profession increase in the group exposed to IR. The findings indicate that the effect of low-dose ionizing radiation on the hematopoietic system is related to the frequency and duration of the dose. Hematological parameters can be sensitive biomarkers of low-dose ionizing radiation; possible disturbances in the hematopoietic system can be recognized before the onset of symptoms, and necessary precautions can be taken promptly.

Background: Dysbaric osteonecrosis (DON) is defined as avascular bone necrosis, usually involving specific parts of the long bones, which is seen in divers or compressed-air workers due to exposure to pressure. We describe a case of DON in an artisanal diving fisherman working underwater for many years. Methods: A 48-year-old male case was admitted to the occupational disease outpatient with left shoulder and arm pain for 1-2 years. Since the age of 20, he has been artisanal diving fishing with a hookah at a depth of 20-25 meters in the sea. In 2011, he received hyperbaric oxygen therapy for widespread pain in the whole body due to decompression sickness (DCS). In the case's left shoulder joint x-ray and magnetic resonance imaging, degenerative changes in the acromioclavicular joint and signal changes consistent with osteonecrosis starting from the subcortical area of the humeral head and extending to the proximal shaft of the humerus were observed. Conclusions: DON is among the most common long-term pathologies in professional divers. In Turkey, as in our case, not applying safe decompression procedures and unsafe diving practices are common among diving fishers. In studies, the frequency of exposure to pressure, duration and depth of dive, insufficient decompression, formation of DCS and increasing age were associated with DON. Today, DON remains an occupational hazard with significant medical and social consequences. Diving fishers should be informed about the sequelae of DCS and trained on the safety measures to be taken.

Background: Taxi drivers have an increased risk of low back pain due to both physical and occupational conditions. This study aims to determine the prevalence of low back pain and occupational risk factors among taxi drivers working in İzmir, Turkey., Methods: This study was conducted with 447 taxi drivers at randomly selected taxi stands between April and September 2021. The questionnaire included demographic, individual, and work-related questions; the Nordic Musculoskeletal Questionnaire; and the Back Pain Functional Scale (BPFS)., Results: The prevalence of low back pain in the last year was 49.7%. In multivariate logistic regression analyses, the risk factors for low back pain included having a body mass index of 25-29.9 kg/m2 (OR= 1.67, 95% CI 1.01-2.76) or ≥30 kg/m2 (OR= 2.15, %95 CI 1.19-3.87), no physical activity (OR= 1.66, 95% CI 1.06-2.62), years of work >10 (OR= 3.23, 95% CI 1.89-5.53), no weekly rest period (OR= 3.11, 95% CI 1.42-6.81), having no lumbar support on the driver's seat (OR:1.67, 95% CI:1.05-2.66), or undecisive job satisfaction (OR= 2.07, 95% CI 1.17-3.66). Being undecided about job satisfaction (OR= 2.34, 95% CI 1.15-4.92) and not having physical activity (OR= 2.10 CI 1.08-4.08) were found to be risk factors for reduced BPFS scores., Conclusion: A strong correlation was found between the frequency of low back pain and the BPFS score and occupational factors. Early detection and management of low back pain are critical to avoid increased low back pain and related injuries among taxi drivers.

Background: Hypertension is a serious disease with increasing worldwide prevalence, leading to life-threatening complications., Methods: This cross-sectional study was carried out in a university hospital. The Occupational Health and Safety Unit data concerning the health examinations of employees were used to determine the prevalence of hypertension in a university hospital and to define the relationship between hypertension and sociodemographic and occupational parameters. Logistic regression analyses were performed for the variables having a significant association with high blood pressure., Results: The data generated during the periodic examination of 3,480 (92%) of all employees (3,780) were analyzed. The prevalence of hypertension was 14.8%. The prevalence of hypertension was found to be 13.5%, 13.9%, and 23.7% among physicians, non-physician healthcare personnel and officers respectively. The logistic regression model revealed a statistically significant correlation between hypertension and male gender, age and BMI., Conclusion: The prevalence of hypertension was highest among staff members. Special programs would facilitate the diagnosis, control, and prevention of high blood pressure among the high-risk groups, especially men, the elderly and the obese hospital employees., (© 2020 Kurtul S et al.)

In this study we aimed to investigate whether there is an association between the neutrophil to lymphocyte ratio (NLR) and severity of coronary artery disease (CAD) in patients with non-ST segment elevation myocardial infarction (NSTEMI) using the SYNTAX score (SXscore). A total of 414 patients with NSTEMI who underwent coronary angiography were enrolled in the study. NLR was measured for all patients at presentation. The study population was then divided into 3 tertiles based on the SYNTAX trial results.(1)) The low syntax group (n = 329) was defined as those with an SXscore ≤ 22, the intermediate syntax group (n = 58) was defined as an SXscore ≥ 23 and < 33, and the high syntax group (n = 27) as those with an SXscore ≥ 33. NLR was significantly lower in patients with a low SXscore compared to patients with an intermediate SXscore or high SXscore (3.7 ± 4 to 4.6 ± 2 and 7.9 ± 4, P < 0.001). Linear regression analysis revealed that NLR (coefficientβ = 0.380, 95%CI: 1.165-1.917, P < 0.001) was significantly associated with the SXscore in patients with NSTEMI. Our results indicate that NLR is independently associated with the severity of CAD in patients with NSTEMI.

Introduction: Sufficient coronary collateral circulation (CCC) protects myocardial tissue against ischemia in patients with coronary chronic total occlusion (CTO). Vitamin D is a steroid hormone which has been related to increased prevalence of hypertension, left ventricular hypertrophy, heart failure, peripheral artery disease, coronary artery disease, myocardial infarction and cardiovascular mortality., Aim: To investigate whether there is an association between serum 25-hydroxy-vitamin D levels and development of CCC in patients with coronary CTO., Material and Methods: A total of 188 patients with CTO at coronary angiography were included in this study. Vitamin D and parathyroid hormone (PTH) levels were measured on the day of coronary angiography. Development of collateral circulation was graded according to the Rentrop classification after coronary angiography. Then, patients were divided into two groups on the basis of CCC grades: group 1 included 68 (36%) patients with poorly developed CCC, and group 2 included 120 (64%) patients with well-developed CCC., Results: Patients with poorly developed CCC had significantly lower serum 25-hydroxy-vitamin D levels compared to those with well-developed CCC (20 ±3 vs. 30 ±6 ng/ml, p<0.0001). Multivariate logistic regression analysis indicated serum 25-hydroxyvitamin D (25(OH)D) (OR = 1.794, 95% confidence interval (CI): 1.453-2.216; p<0.001) as an independent predictor of poor collateral flow in patients with CTO., Conclusions: Low vitamin D level is an independent predictor of poor CCC in patients with CTO.

We investigated the predictors of endothelial dysfunction in patients with rheumatoid arthritis (RA) by brachial artery flow-mediated vasodilatation (FMD). The study population included 50 patients with RA and 30 controls. Disease activity score (DAS28) was calculated for patients with RA. An FMD response <7% was accepted as impaired FMD. Brachial artery Doppler study revealed that in patients with RA, FMD% was significantly lower as compared with controls (6.6% ± 3.5% vs 9.7% ± 41%, P = .002). After multivariate logistic regression analysis, erythrocyte sedimentation rate (ESR; OR: 1.086, 95% confidence interval [CI]: 1.012-1.167, P = .023), duration of RA (OR: 1.392, 95% CI: 1.044-1.856, P = .024), and DAS28 (OR: 3.335, 95% CI: 1.067-10.42, P = .038) were independent predictors of impaired FMD in patients with RA. Endothelial function is impaired in patients with RA. Disease duration, DAS28, and ESR indicating active inflammation are independent predictors of impaired FMD in patients with RA., (© The Author(s) 2013.)

The relationship between extent, severity, and complexity of coronary artery disease (CAD) in patients with ST-segment elevation myocardial infarction (STEMI) and serum γ-glutamyl transferase (GGT) activity has not been adequately studied. We evaluated the relationship between GGT activity and the burden of CAD as assessed by SYNTAX score (SXscore) in patients with STEMI. A total of 243 patients (age 67.1 ± 8.6, 77.4% male) with STEMI were divided into 2 groups. Low- and high-SXscore groups were defined as SXscore <22 and ≥22, respectively. Admission GGT activities were similar between low- and high-SXscore groups (32 ± 17 vs 33 ± 18; P = .625), and there was no significant correlation between GGT activity and SXscore. Although there was an association between high SXscore and major adverse cardiovascular events, as expected, our results did not demonstrate any relationship between admission GGT activities and complexity and extent of the coronary lesions in patients with STEMI., (© The Author(s) 2013.)

Objective: To investigate early markers of atherosclerosis in patients with nasal polyposis (NP) through measurements of carotid artery intima-media thickness (CIMT), flow-mediated vasodilatation (FMD) of the brachial artery and serum paraoxonase-1 (PON-1) activity., Methods: Forty-five patients with NP were included in the study group and 45 healthy individuals in the control group. The diagnosis of patients with NP was predicated on anterior rhinoscopy, endoscopic nasal examination and coronal paranasal sinus computed tomography (CT). Measurements of CIMT and FMD of the brachial artery were performed by high-resolution ultrasonography. Serum PON-1 activity was evaluated by measuring the rate of paraoxon hydrolysis., Results: Mean CIMT values were found to be increased in the NP group compared to the control group. However, mean FMD % values and serum PON-1 activity were significantly lower in the NP group compared to the control group. Moreover; the endoscopic polyps' scores and paranasal sinus CT scores were positively correlated with CIMT and negatively correlated with FMD % values and PON-1 activity. Disease duration also was positively correlated with CIMT and negatively correlated with FMD % values., Conclusion: Impaired FMD, increased CIMT and decreased serum PON-1 activity may be considered to be risk factors for accelerated atherosclerosis in patients with NP who may have subclinical atherosclerosis and be at risk for cardiovascular events in the future., (Copyright © 2013 Elsevier Ireland Ltd.

We investigated the association between coronary artery ectasia (CAE) and Neutrophil-to-lymphocyte ratio (NLR), an indicator of the inflammatory state. The study population included 434 patients (247 males, mean age 62 ± 10 years) including 230 patients with isolated CAE and 104 patients with coronary artery disease and 100 patientss with normal coronary arteries. The NLR was measured at admission and 30 days after coronary angiography in all the patients. The NLR was significantly higher in patients with CAE than those with normal coronary arteries (2.2 ± 0.6-1.3 ± 0.6, P < .001). Linear regression analyses revealed that NLR (coefficient β = -.61, P < .001) was significantly associated with severity of CAE. The NLR is significantly higher in patients with CAE compared to controls with normal coronary arteries, and NLR is associated with severity of CAE.

Purpose: Cardiovascular diseases are the leading cause of death in patients with non-alcoholic steatohepatitis (NASH). We aimed to investigate the presence of endothelial dysfunction and whether serum concentrations of liver enzymes may reflect the severity of such an endothelial dysfunction in patients with NASH., Methods: Fifty patients with NASH diagnosed by liver biopsies and 30 healthy controls were included. Blood samples after fasting were harvested for measurements of glucose, insulin, cholesterol, triglyceride, and liver enzymes. All patients underwent transthoracic echocardiography and brachial and carotid artery Doppler ultrasonography to evaluate flow-mediated dilatation (FMD) and carotid artery intima-media thickness (CIMT)., Results: Patients with NASH had impaired FMD (4.9 ± 2.8% to 9.3 ± 4.4%, P < 0.001) and higher CIMT (0.79 ± 0.16 mm to 0.64 ± 0.11 mm, P < 0.001) when compared with healthy controls. Linear regression analyses revealed that serum concentrations of gamma glutamyl transferase (GGT) and alanine transaminase (ALT) were associated with FMD and CIMT., Conclusions: Patients with NASH have impaired FMD and increased CIMT when compared with healthy controls. In patients with NASH, serum concentrations of GGT and ALT might have a predictive value for FMD and CIMT.

Objectives: In this study, we aimed to investigate whether there is an association between mean platelet volume (MPV), gamma-glutamyltransferase (GGT) and uric acid and coronary artery ectasia (CAE) in a large patient population., Study Design: A total of 406 patients (245 male, 161 female; mean age: 55±9 years) were selected retrospectively as the study population from among 3265 individuals who underwent coronary angiography between August 2011 and December 2012. Information regarding blood tests of the patients obtained during hospitalization was extracted from the institute electronic database., Results: MPV, GGT and uric acid levels were significantly higher in subjects with stenotic coronary artery disease (CAD) and in subjects with both CAD and CAE compared with subjects with isolated CAE and subjects with normal coronary arteries (NCA). There were no significant differences between the isolated CAE and NCA groups in terms of MPV (8.6±1.2 fL vs. 8.6±1.1, respectively, p=0.993), serum GGT (33±15 U/L vs. 30±15 U/L, respectively, p=0.723) and uric acid levels (5.4±1.6 mg/dl vs. 5.2±1.7 mg/dl, respectively, p=0.845)., Conclusion: Unlike previous studies, our study failed to demonstrate any association between CAE and MPV, uric acid and GGT levels.

Objectives: Sufficient coronary collateral circulation (CCC) protects myocardial tissue against ischemia in patients with coronary chronic total occlusion (CTO). In this study, we aimed to investigate whether there is an association between serum γ-glutamyl transferase (GGT) levels and development of CCC in patients with coronary CTO., Materials and Methods: A total of 203 patients with CTO at coronary angiography were included in this study. On the day of admission to the hospital, blood samples were taken and GGT levels were analyzed for all patients. Development of collateral circulation was graded according to the Rentrop classification after coronary angiography. Then, patients were divided into two groups on the basis of CCC grades: group 1 included 99 patients (49%) with poorly developed CCC, and group 2 included 104 patients (51%) with well-developed CCC., Results: Patients with poorly developed CCC had significantly higher serum GGT levels compared with those with well-developed CCC, (66.5±16 vs. 51.8±10 U/l, P<0.0001). Correlation analysis showed an inverse correlation between GGT levels and the Rentrope score (r=-0.579, P<0.001). Logistic regression analysis showed that GGT level was an independent predictor of poorly developed CCC (odds ratio 0.92, 95% confidence interval 0.90-0.94; P<0.001)., Conclusion: Increased serum GGT levels independently predict poorly developed CCC in patients with coronary CTO. Our results show that GGT is a simple and readily available marker for sufficiency of CCC in patients with CTO.

Objective: In a significant proportion of patients with ST-elevation myocardial infarction (STEMI), microvascular and myocardial reperfusion cannot be regained despite successfully restored thrombolysis in myocardial infarction (TIMI) grade 3 epicardial blood flow. Myocardial blush grade (MBG) is a reliable marker for microvascular patency and predicts short-term and long-term mortality after primary percutaneous coronary intervention (PCI) in patients with acute STEMI, independent of other variables. Mean platelet volume (MPV), a unique measure of platelet size, is an indicator of platelet reactivity. In this study, we aimed to investigate the relation of admission MPV with postinterventional MBG in patients with STEMI and TIMI grade 3 flow at infarct artery after primary PCI., Materials and Methods: Three hundred and ten patients were selected as a study group among patients with STEMI and TIMI grade 3 epicardial blood flow after primary PCI. Blood samples for analysis were obtained during the initial evaluation of patients at the emergency department. MBGs of patients were classified at the end of angioplasty. Patients with MBG 0 and 1 were defined as having poor myocardial blush and patients with MBG 2 and 3 were defined as having normal myocardial blush., Results: Patients with poor myocardial blush had higher admission MPV (10.5±1.3 to 9.1±1 fl, P<0.001), higher peak creatine kinase myocardial band isoenzyme levels (260±53 to 190±38 U/l, P<0.001), higher white blood cell count (11.3±4 to 10.3±3×10/μl, P=0.012), and lower left ventricular ejection fraction (42±7 to 51±8%, P<0.001) compared with patients with normal myocardial blush. Linear regression analysis showed that admission MPV was significantly associated with postinterventional MBG (coefficient=0.598, P<0.001). Cardiovascular mortality (13-5%, P=0.013) and acute-subacute stent thrombosis at 3 months (12-8%, P=0.028) were significantly higher in patients with poor postinterventional myocardial blush compared with those with normal myocardial blush., Conclusion: The MPV measured at admission is significantly associated with poor postinterventional MBG in patients with STEMI and TIMI grade 3 flow at infarct artery after primary PCI.

Objective: The aim of this study was to investigate the relationship between psoriasis and heart rate recovery (HRR) index., Patients and Methods: A total of 50 patients with a diagnosis of psoriasis and 32 healthy volunteers were included in the study. In all patients, a stress test was performed to calculate the HRR index in a manner which aimed to reach the age-specific maximum heart rate. HRR indices were calculated in all patients and controls., Results: HRR (beats/minute) indices after the 1st (HRR1, 26 ± 10 vs. 33 ± 8, p = 0.002), 2nd (44 ± 11 vs. 50 ± 6, p = 0.002), 3rd (51 ± 7 vs. 63 ± 8, p < 0.001), 4th (54 ± 7 vs. 65 ± 8, p < 0.001) and 5th (57 ± 8 vs. 70 ± 10, p < 0.001) minutes of the recovery period were significantly lower in the psoriasis group compared to healthy controls. In addition, HRR1 was significantly correlated with duration of psoriasis (r = 0.541, p < 0.001) and psoriasis area and severity index score (r = 0.511, p < 0.001)., Conclusion: HRR was lower in patients with psoriasis. Given the prognostic value of this test, patients with psoriasis might be at risk for future cardiovascular events and cardiovascular mortality., (Copyright © 2013 S. Karger AG, Basel.)
