In the Turkish health care system and hospitals it is very common to witness role conflict and ambiguity among health care personnel. Often this is due to a lack of clarity as to what is expected and required of them. The unfortunate and unavoidable result is a high level of burnout caused by uncertain working conditions in Turkish hospitals. The objectives of this study were to determine the level of role conflict, role ambiguity, and burnout of physicians and nurses working in hospitals, to see the relationship between role conflict, ambiguity and burnout level, to reveal the effects of organisational and indvidual characteristics on the burnout level of physicians and nurses. The study was conducted in three hospitals attached to the Ministry of Health (MoH) of Turkey. 149 nurses and 83 physicians were included in the sample of this study although several efforts of reminders and additional visits to the hospitals to increase the response rate. Structural Equational Modelling (SEM) was chosen to estimate the effects of certain selected individual and organisational variables that were determined by a set of correlation and biovariate analyses on role conflict and ambiguity as well as the burnout level. The SEM results showed that working in surgical units, having less working experience and choosing the profession unwillingly had significant and negative direct effects on the burnout level of the physicians and nurses in the sample of this study. Decreasing the level of role conflict and ambiguity would serve to decrease the level of burnout. In order to decrease the level of role conflict, ambiguity, and burn out level for nurses and physicans, serious efforts must be made to clarify role definitions, increase resources, and employ conflict management methods. 相似文献

With the growing understanding of the role of inflammation in patients with atherosclerotic disease, studies have focused on high-sensitivity C-reactive protein (hs-CRP) and other inflammatory markers in their association with outcomes in ST-segment elevation myocardial infarction. The goal of this study was to investigate the association of the neutrophil/lymphocyte (N/L) ratio and in-hospital major adverse cardiac events (MACEs) in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention (PCI). The association of hs-CRP and N/L ratio on admission with Thrombolysis In Myocardial Infarction (TIMI) flow grade after PCI was assessed in 418 consecutive primary patients with PCI. The N/L ratio was significantly higher in the no-reflow group (TIMI grade 0/1/2 flow, n = 158) compared to that of the normal-flow group (TIMI grade 3 flow, n = 260, 4.6 ± 1.7 vs 3.1 ± 1.9, p <0.001). In-hospital MACEs were significantly higher in patients with no reflow (23% vs 7%, p <0.001). There was a significant and positive correlation between hs-CRP and N/L ratio (r = 0.657, p <0.001). In receiver operating characteristic analysis, N/L ratio >3.3 predicted no reflow with 74% sensitivity and 83% specificity. In a multivariate regression model, N/L ratio remained an independent correlate of no reflow (odds ratio [OR] 1.54, 95% confidence interval [CI] 1.34 to 1.76, p <0.001) and in-hospital MACEs (OR 1.14, 95% CI 0.98 to 1.32, p = 0.043). The N/L ratio, an inexpensive and easily measurable laboratory variable, is independently associated with the development of no reflow and in-hospital MACEs in patients with ST-segment elevation myocardial infarction undergoing primary PCI. 相似文献

Aim: This study examined and classified patients who were treated at the Faculty of Dentistry at Ankara University Dentistry to determine the incidence of different types of stylohyoid ligament calcification (SLC) using panoramic radiographs. In addition, it also assessed the possible causative symptoms and Eagle’s syndrome in cases of styloid process elongation. Methods: The study consisted of 2000 patients (1161 females and 839 males), aged 3–88 years, who were treated at our clinic. The panoramic radiographs were evaluated as part of this study. Results: Panoramic radiography examination revealed SLC in 1350 patients. Both‐sided (right and left), type 1 SLC was observed in 345 patients, while types 2–4 were found in 203, 418, and 384 patients, respectively. Conclusion: The incidence of SLC was found to be higher in female patients when compared to male patients. In addition, calcifications were seen more often at age 50–59 years, and the incidence of calcification was found to increase with age. Two Eagle’s syndrome cases were diagnosed among a total of 2000 patients. Finally, it was determined that the incidence of calcified stylohyoid ligament is higher in patients with systemic diseases. 相似文献

The main purpose of this study was to investigate the relation between carotid intima-media thickness (CIMT) and coronary artery disease (CAD) complexity. Consecutive patients (n = 360) with CAD confirmed by coronary angiography were enrolled. Mean CIMT and the overall SYNTAX score (SXscore) were 0.87 ± 0.12 mm and 15 ± 9, respectively. In univariate analysis, there was a significant correlation between the overall SXscore and CIMT (r = .42, P < .001), age (r = .23, P < .001), hypertension (r = .27, P = 0.001), diabetes (r = 0.11, P = 0.02), smoking (r = .24, P = .01), dyslipidemia (r = .2, P = 0.03), and β-blocker use (r = .19, P < .001). In multivariate analysis, CIMT (β = .34, P < .001) and age (β = .11, P < .019) were independently associated with SXscore. We have demonstrated a significant relation between CIMT and SXscore. Although this study is correlative and no causative conclusions can be drawn, our findings suggest that increased CIMT could reflect complex coronary artery lesions. 相似文献

Lymphomatoid granulomatosis is a rare, diffuse, large B-cell lymphoma that is positive for Epstein-Barr virus. A multiorgan process, it manifests itself chiefly in the lungs but can also affect the skin, nervous system, and kidneys. Cardiac involvement and pericardial effusion are very unusual. We report the case of a 62-year-old man with lymphomatoid granulomatosis involving the heart and lungs. Diagnosis was confirmed with wedge biopsy at pericardiotomy, and the patient was treated with cyclophosphamide, prednisolone, and vincristine. Although the patient was still symptomatic at 6-month follow-up, he was in partial remission with improved functional capacity. 相似文献

Background
The aim of this study was to examine whether treatment with montelukast, a selective leukotriene antagonist, would affect anastomotic healing in a reperfused colon rat model with remote ischemia/reperfusion injury.Methods
Rats (n = 12 per group) were intraperitoneally administered normal saline or 10 mg/kg montelukast sodium 60 minutes before and for 5 days after surgery. Ischemia was induced for 45 minutes through superior mesenteric artery occlusion. A left colon anastomosis was made. Blood and perianastomotic tissue samples were obtained on postoperative day 5.Results
Mean anastomotic bursting pressures of the control and montelukast groups were 159.17 ± 29.99 and 216.67 ± 26.40, respectively (P < .001). Compared with saline, montelukast treatment increased the mean tissue hydroxyproline level (2.46 ± .30 vs 3.61 ± .33 μmol/L) and decreased tissue caspase-3 activity (36.06 ± 5.72 vs 21.78 ± 3.87) and malondialdehyde levels (3.43 ± .34 vs 2.29 ± .34 nmol/g) (P < .001 for all). Other plasma markers of injury also showed differences.Conclusions
Montelukast prevented ischemia/reperfusion-induced damage in a rat model of colonic anastomotic wound healing. 相似文献80.

Fever of unknown origin (FUO) is a diagnostic challenge for the practising physician. Detailed medical history, physical examination, non-invasive laboratory tests, and radiologic examinations compose the first level in the diagnostic approach to the FUO. When a diagnosis cannot be established with these procedures, some invasive diagnostic techniques and finally exploratory laparotomy are performed. Although advanced diagnostic measures and imag-ing-guided less invasive procedures have decreased the need, laparotomy remains as a final diagnostic method for FUO cases. In this study we evaluate the role and importance of laparotomy in the diagnosis of our FUO cases. In 17 out of 126 patients (8 male, 9 female, the median age 35.8 years) hospitalized in our clinic between 1982 and 2002 with the diagnosis of FUO, the diagnosis was established by laparotomy. The diagnosis was made directly in 13 patients, and indirectly (by excluding other diseases) in 2 patients. In several FUO series, the contribution of laparotomy to the diagnosis of FUO was reported as 27-100%. This rate was found to be 88% in the present study. During laparotomy on 17 cases, tissue samples were taken from spleen, liver, intra-abdominal and mesenteric lymph nodes. Pathologic examination of these tissue samples revealed miliary tuberculosis in 4; non-Hodgkin’s lymphoma in 3; Hodgkin’s lymphoma in 3; liver tumour in 1; hairy cell leukemia in 1; peritonitis carcinomatosis in 1. In the patients with miliary tuberculosis, the liver (3) and/or spleen (2), and/or lymph node (3) revealed caseating granulomas. Laparotomy diagnosed 3 of 5 cases whose abdominal ultrasonography and computerized tomography were normal. In conclusion, although advanced diagnostic methods decreased the need for laparotomy in FUO, if non-invasive and invasive diagnostic measures fail, laparotomy may contribute to the diagnosis. The selection of the patient and the timing are important for laparotomy. 相似文献
