It is unclear whether cancer-related epidemiology after kidney transplantation is translatable between countries. In this population-cohort study, we compared cancer incidence and all-cause mortality after extracting data for every kidney-alone transplant procedure performed in England and New York State (NYS) between 2003 and 2013. Data were analyzed for 18,493 and 11,602 adult recipients from England and NYS respectively, with median follow up 6.

Article Synopsis
  • Many herbal medicines in alternative medicine are not well-researched for safety, potentially putting users at risk.
  • This study tested the genotoxic (mutagenicity) and cytotoxic (cell toxicity) effects of various fruit extracts traditionally used in folk medicine using specific bacteria and cell lines.
  • Results indicated that both aqueous and ethanolic extracts showed significant mutagenicity and cytotoxicity, suggesting that these fruit extracts may not be safe for use, highlighting the need for more thorough safety evaluations.

Viral hepatitis, an inflammatory liver disease, is caused by various genotypes of hepatitis C viruses (HCV). Hepatitis C slowly sprouts into fibrosis, which progresses to cirrhosis. Over a prolonged period of time compensated cirrhosis can advance to decompensated cirrhosis culminating in hepatic failure and death.

Purpose: To investigate the association of ABCB1-C3435T transition with breast cancer risk which was followed by a meta-analysis.

Methods: In a case-control study we collected blood samples from 290 women (including 150 breast cancer patients and 140 healthy controls). ABCB1-C3435T genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.

Cell populations with differing proliferative, stem-like and tumorigenic states co-exist in most tumors and especially malignant gliomas. Whether metabolic variations can drive this heterogeneity by controlling dynamic changes in cell states is unknown. Metabolite profiling of human adult glioblastoma stem-like cells upon loss of their tumorigenicity revealed a switch in the catabolism of the GABA neurotransmitter toward enhanced production and secretion of its by-product GHB (4-hydroxybutyrate).

In the past decades liver transplantation (LT) has become the treatment of choice for patients with end stage liver disease (ESLD). The chronic shortage of cadaveric organs for transplantation led to the utilization of a greater number of marginal donors such as older donors or donors after circulatory death (DCD). The improved survival of transplanted patients has increased the frequency of long-term complications, in particular chronic kidney disease (CKD).

Objectives: This study was designed to determine the comparative efficacy of different scoring system in assessing the prognosis of critically ill patients.

Methods: This was a retrospective study conducted in medical intensive care unit (MICU) and high dependency unit (HDU) Medical Unit III, Civil Hospital, from April 2012 to August 2012. All patients over age 16 years old who have fulfilled the criteria for MICU admission were included.

Ductal spread (DS) of acinar adenocarcinoma of the prostate can lead to an incomplete replacement of the benign epithelium by cancer cells, resulting in a lesion that can be indistinguishable from high-grade prostatic intraepithelial neoplasia (HGPIN). Kovi and colleagues demonstrated 30 years ago that there is a significant association between the presence of DS and local extent of invasive adenocarcinoma, making the distinction between DS and HGPIN clinically relevant. However, despite the existence of certain morphologic features that are suggestive of DS, a definitive differentiation between the aforementioned lesions cannot always be attained.

The present study was designed to evaluate the anti-inflammatory, analgesic and antipyretic activities of the aqueous and ethanolic extracts of seeds of Buchanania lanzan Spreng. Albino mice were used as experimental animals to evaluate these activities. The study was performed in three phases; Phase-I for evaluation of anti-inflammatory activity, Phase-II for antipyretic and Phase-HI for analgesic activities were evaluated.

Previous publications have described unethical organ procurement procedures in the People's Republic of China. International awareness and condemnation contributed to the announcement abolishing the procurement of organs from executed prisoners starting from January 2015. Eighteen months after the announcement, and aligned with the upcoming International Congress of the Transplantation Society in Hong Kong, this paper revisits the topic and discusses whether the declared reform has indeed been implemented.

Background: Outcomes for weekend hospital admissions or emergency procedures have become a topical and controversial issue for the UK National Health Service. Deceased-donor kidney transplantation is frequently performed at weekends and evidence for its relative safety are lacking.

Methods: We undertook a population-based cohort analysis, obtaining data from every deceased-donor kidney-alone transplant procedure performed in England between January 2003 and December 2014.

Background: Causes of "true" late kidney allograft failure remain unclear as study selection bias and limited follow-up risk incomplete representation of the spectrum.

Methods: We evaluated all unselected graft failures from 2008-2014 (n = 171; 0-36 years post-transplantation) by contemporary classification of indication biopsies "proximate" to failure, DSA assessment, clinical and biochemical data.

Results: The spectrum of graft failure changed markedly depending on the timing of allograft failure.

Article Synopsis
  • The study aimed to investigate the rates and reasons for surgical cancellations and no-shows at Ibri Regional Hospital in Oman, an important aspect of operating theatre (OT) utilization.
  • A total of 4,814 elective surgeries were scheduled in 2014, with 1,235 (26%) being cancelled; the main reason for cancellations was patient no-shows, accounting for 63%.
  • The findings suggest that improved management practices, such as regular audits and hiring a procedure booking coordinator, could help reduce cancellation rates and better utilize hospital resources.

Background: Lifestyle modification is widely recommended to kidney allograft recipients post transplantation due to the cardiometabolic risks associated with immunosuppression including new-onset diabetes, weight gain and cardiovascular events. However, we have no actual evidence that undertaking lifestyle modification protects from any adverse outcomes post transplantation. The aim of this study is to compare whether a more proactive versus passive interventional approach to modify lifestyle is associated with superior outcomes post kidney transplantation.

Sex differences in stress-related diseases such as stroke and stomach cancer are well established, but the mechanisms underlying this phenomenon remain unknown. Despite the fact that sexual hormones play an important role in the high resistance of females to harmful effects of stress compared with males, the regulation of oxygenation status can be a potential factor, which might explain sex differences in stress-induced cerebrovascular catastrophes in newborn rats and in mutagens activation in adult rats with stomach cancer.

Oncogenic Ras signalling occurs frequently in many human cancers. However, no effective targeted therapies are currently available to treat patients suffering from Ras-driven tumours. Therefore, it is imperative to identify downstream effectors of Ras signalling that potentially represent promising new therapeutic options.
