    <p>Abstract</p> <p>Introduction</p> <p>Autopsy series have shown that metastasis to the thyroid gland has occurred in up to 24% of patients who have died of cancer. Neuroendocrine tumors may metastasize to thyroid gland.</p> <p>Case presentations</p> <p>Case 1 was a 17-year-old Turkish woman who was referred from our Endocrinology Department for a thyroidectomy for treatment of neuroendocrine tumor metastasis. She was treated with a bilateral total thyroidectomy. Histopathological examination results were consistent with a neuroendocrine tumor; neoplastic cells showed strong immunoreactivity to chromogranin A and synaptophysin, but the immunohistochemical profile was inconsistent with medullary thyroid carcinoma in that the tumor was negative for calcitonin, carcinoembryonic antigen, and thyroid transcription factor-1.</p> <p>Case 2 was a 54-year-old Turkish woman who presented with a 3-cm nodule on her right thyroid lobe. She had undergone surgery for a right lung mass four years previously. After a right pneumonectomy, thymectomy and lymph node dissection, a typical carcinoid tumor was diagnosed. Under ultrasonographic guidance, fine needle aspiration biopsy of her right thyroid pole nodule was performed and the biopsy was compatible with a neuroendocrine tumor metastasis. She was treated with a bilateral total thyroidectomy. Histopathological examination indicated three nodular lesions, 5 cm and 0.4 cm in diameter in her right lobe and 0.1 cm in diameter in her left lobe. The tumors were consistent with a neuroendocrine phenotype, showing strong immunoreactivity to chromogranin A and synaptophysin.</p> <p>Conclusion</p> <p>Thyroid nodules detected during follow-up of neuroendocrine tumor patients should be thoroughly investigated. A fine needle aspiration biopsy of the thyroid confirms the diagnosis in most cases and leads to appropriate management of those patients and may prevent unnecessary treatment approaches.</p

    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

    How managers perceive green marketing in tourism is one of the most important factors for enterprises in becoming green establishments. The aim of the study is also to determine managers' perceptions of green marketing. In this regard, the study investigated the hotel managers' perceptions of green marketing in Antalya. The data on the hotel managers' views were collected through surveys and it was determined that the measurement tool developed through the study had an internal consistency reliability between 0.83 and 0.91. Therefore, it can be stated that the scale has a high level of reliability. It was determined that the hotel managers' perceptions of green marketing varied, depending on the locations, types of the hotels, and the managers' years of experience in management in the tourism sector

    Barriers to environmental management systems(EMS): Case of 4 and 5 star hotels in Istanbul.

    In the late 1990s with studies that focused on the driving forces, costs and benefits and nature of such systems began about EMS. However, in tourism, very little research has been conducted on EMS, except for a few studies on environmental management, such as the environmental protection practices and environmental performance of hotels. In this study, we tried to determine the barriers to EMS of 4 and 5 stars’ hotels operating in Istanbul. In this regard, the aim of this study is to encourage the hotels how they implement EMS through eliminating the barriers. The data were collected from the top and mid-level managers of hotels between October and December in 2016 by face to face survey. Data gained from 114 hotels was analyzed via factor analyses, independent samples t-test and ANOVA. It was found that EMS barriers can be examined under three dimensions as; (1) lack of knowledge, skills and professional advice, (2) uncertainty of outcomes, (3) lack of resources and costs. On the other hand, hotels characteristics play an important role on these dimensions

    Purpose: The purpose was to evaluate choroidal thickness via spectral domain optical coherence tomography (SD-OCT) and to compare the data with those of 24-h blood pressure monitoring, elastic features of the aorta, and left ventricle systolic functions, in patients with systemic hypertension. Materials and Methods: This was a case-control, cross-sectional prospective study. A total of 116 patients with systemic hypertension, and 116 healthy controls over 45 years of age, were included. Subfoveal choroidal thickness (SFCT) was measured using a Heidelberg SD-OCT platform operating in the enhanced depth imaging mode. Patients were also subjected to 24-h ambulatory blood pressure monitoring (ABPM) and standard transthoracic echocardiography (STTE). Patients were divided into dippers and nondippers using ABPM data and those with or without left ventricular hypertrophy (LVH+ and LVH-) based on STTE data. The elastic parameters of the aorta, thus aortic strain (AoS), the beta index (BI), aortic distensibility (AoD), and the left ventricular mass index (LVMI), were calculated from STTE data. Results: No significant difference in SFCT was evident between patients and controls (P ≤ 0.611). However, a significant negative correlation was evident between age and SFCT in both groups (r = −0.66/−0.56, P ≤ 0.00). No significant SFCT difference was evident between the dipper and nondipper groups (P ≤ 0.67), or the LVH (+) and LVH (-) groups (P ≤ 0.84). No significant correlation was evident between SFCT and any of AoS, BI, AoD, or LVMI. Discussion : The choroid is affected by atrophic changes associated with aging. Even in the presence of comorbid risk factors including LVH and arterial stiffness, systemic hypertension did not affect SFCT

    . Purpose. To compare the effects of different anesthesia techniques on tourniquet-related ischemia-reperfusion by measuring the levels of malondialdehyde (MDA), ischemia-modified albumin (IMA) and neuromuscular side effects. Methods. Sixty ASAI-II patients undergoing arthroscopic knee surgery were randomised to three groups. In Group S, intrathecal anesthesia was administered using levobupivacaine. Anesthesia was induced and maintained with sevoflurane in Group I and TIVA with propofol in Group T. Blood samples were obtained before the induction of anesthesia ( 1 ), 30 min after tourniquet inflation ( 2 ), immediately before ( 3 ), and 5 min ( 4 ), 15 min ( 5 ), 30 min ( 6 ), 1 h ( 7 ), 2 h ( 8 ), and 6 h ( 9 ) after tourniquet release. Results. MDA and IMA levels increased significantly compared with baseline values in Group S at 2 -9 and 2 -7 . MDA levels in Group T and Group I were significantly lower than those in Group S at 2 -8 and 2 -9 . IMA levels in Group T were significantly lower than those in Group S at 2 -7 . Postoperatively, a temporary 1/5 loss of strength in dorsiflexion of the ankle was observed in 3 patients in Group S and 1 in Group I. Conclusions. TIVA with propofol can make a positive contribution in tourniquet-related ischemia-reperfusion
