Background

Turkey is one of the countries facing a serious organ shortage problem, with thousands of patients with end-stage organ failure. The Social Security Institution started to increase the reimbursement for transplantation operations in 2007 to solve this problem, and this policy has continued since then. Although the number of transplantation centers and operations in Turkey increased in this term, according to organ donation and transplantation statistics from the Ministry of Health, the rate of organ retrieval from deceased organ donors has decreased.

Methods

This study was performed with the purpose of retrospectively analyzing (between the years 2005 and 2015) the number of brain deaths and donors after brain death in hospitals that are affiliated with the Istanbul Regional Coordination Office and have transplantation units. Data were collected via the website of the Ministry of Health. Hospitals were categorized as those directly affiliated with the Ministry of Health, university hospitals, and private hospitals.

Results

This study found that the number of transplantation centers has increased >3 times since 2005, and the number of private transplantation centers has increased 9 times for the same period. We also found that the number of brain deaths, donors after brain death in hospitals, and number of brain deaths and donors after brain death per hospital had varied throughout the study years.

Conclusions

Although the number of transplantation centers has increased since 2005, the number of brain deaths and donors after brain death has not increased to the same extent for this period in these hospitals that have transplantation units.  相似文献

ObjectivesAlthough endoscopic management is considered as the first-line treatment for biliary strictures, it may be challenging in living donor liver transplant recipients due to the complex nature of duct-to-duct reconstruction. In this study we present the use of a pigtail drainage catheter as a biliary stent to treat biliary strictures after a living donor liver transplant.MethodsTwenty-seven patients with biliary strictures were treated with our novel technique. In this technique, a pigtail catheter was trimmed into 3 parts (proximal, middle, and distal portions). A suture string was passed through the distal hole of the middle portion, which was then reversed and used as a stent while the proximal portion was used as a pusher. Following balloon dilation of the stenotic segment, the distal, reversed middle, and proximal portions were loaded over the guidewire. After proper placement of the stent, the retractor suture string, pusher, and guidewire were removed. The stent was removed during the third or fourth month of placement through endoscopic retrograde cholangiopancreatography (ERCP) in all patients.ResultsNo significant complications developed during the procedure or follow-up period. Ten patients required re-stenting by ERCP during the same session. The mean follow-up period was 2 years. Cholestase enzymes and bilirubin levels were within normal limits in all patients during follow-up.ConclusionStents derived from drainage catheter facilitate treatment of biliary strictures in patients not eligible for the retrograde approach. This stent is cheap, easy to implement, can be easily removed by ERCP, and re-stenting can be applicable in retrograde if needed.  相似文献

BACKGROUND: Members of a scheme awarding injury pensions may allege that the onset of diabetes was precipitated or caused by depression induced by work in order to claim an injury award. AIMS: To quantify the association between depression and subsequent development of type 2 diabetes in order to determine whether an individual in a pension scheme that awards injury pensions, who develops type 2 diabetes, should be awarded an injury pension, if the development of the diabetes followed a work-related depressive episode. METHODS: Electronic and hand literature searches up to December 2006. Relative risk estimates from cohort studies of adults were pooled using fixed and random effects models. Attributable risk fraction was calculated using the Levin formula. RESULTS: The presence of depression or depressive symptoms was associated with increased risk of subsequently developing type 2 diabetes. The pooled fully adjusted relative risk estimate from the three highest quality studies was 1.25 (95% CI: 1.02-1.48) and was homogenous. However, depression was no more frequent among those with and without prevalent, but previously undiagnosed, type 2 diabetes. CONCLUSION: Depression is associated with subsequent development of type 2 diabetes. However, the relative risk estimate is small and only 20% of cases of diabetes can be attributed to depression in people with both conditions. Further research is needed to determine possible causal mechanisms for the association and to ascertain whether depression and diabetes may have a common aetiology.  相似文献

AimsThese multidisciplinary guidelines aim to provide clinically helpful, evidence-based recommendations on the surgical management of the axilla in patients who have received neo-adjuvant chemotherapy for early breast cancer.Materials & methodsFollowing a review of published evidence, a writing group representing all disciplines quorate within a breast cancer multidisciplinary meeting prepared the guidelines.Key recommendationsIn patients presenting with clinically node negative axillae, sentinel node biopsy (SNB) may be performed prior to or on completion of neo-adjuvant chemotherapy (NACT). In patients presenting with clinically node positive axillae, SNB may be safely considered following completion of NACT. Four nodes should be removed with dual mapping. If evidence of complete pathological response of previous metastases is seen, axillary radiotherapy may be offered. If residual cancer (isolated tumour cells, micro- or macrometastes) is seen within the SNB, offer axillary node dissection.  相似文献

This paper investigates the comprehensive compassionate care reform programme within the National Health Service (NHS) in England. Through a synoptic reading of policy documents, we show how ‘compassion’ is introduced as an overarching meta‐virtue designed to govern relationships and formal positions in health care. Invoking an ‘ethics of office’ perspective, mainly drawing on the thinking of Max Weber, we evaluate the promotion of compassion as a managerial technology and argue how seemingly humanistic and value‐based approaches to healthcare management might have unintended consequences for the quality of care and the conduct of health professionals that in some ways resemble and in some ways exceed those of the more traditional New Public Management measures, which the new compassion paradigm is expected to outdo. In the paper's final sections, we turn to the original work of the nursing icon Florence Nightingale to argue that compassion and other virtues should continuously be formulated and re‐formulated in relation to the role‐specific skills and duties of particular offices in the healthcare sector.  相似文献
