Background and objectives
There is a shortage of kidneys for transplant, and many patients on the deceased donor kidney transplant waiting list would likely benefit from kidneys that are currently being discarded. In the United States, the most common reason given for discarding kidneys retrieved for transplant is procurement biopsy results. This study aimed to compare biopsy results from discarded kidneys with discard attributed to biopsy findings, with biopsy results from comparable kidneys that were successfully transplanted.Design, setting, participants, & measurements
In this retrospective, observational, case-control study, biopsy reports were examined from 83 kidneys discarded in 2010 due to biopsy findings (cases), 83 contralateral transplanted kidneys from the same donor (contralateral controls), and 83 deceased donors randomly matched to cases by donor risk profile (randomly matched controls). A second procurement biopsy was obtained in 64 of 332 kidneys (19.3%).Results
The quality of biopsy reports was low, with amounts of tubular atrophy, interstitial inflammation, arteriolar hyalinosis, and acute tubular necrosis often not indicated; 69% were wedge biopsies and 94% used frozen tissue. The correlation between first and second procurement biopsies was poor; only 25% of the variability (R2) in glomerulosclerosis was explained by biopsies being from the same kidney. The percentages of glomerulosclerosis overlapped substantially between cases, contralateral controls, and randomly matched controls: 17.1%±15.3%, 9.0%±6.6%, and 5.0%±5.9%, respectively. Of all biopsy findings, only glomerulosclerosis>20% was independently correlated with discard (cases versus contralateral controls; odds ratio, 15.09; 95% confidence interval, 2.47 to 92.41; P=0.003), suggesting that only this biopsy result was used in acceptance decisions. One-year graft survival was 79.5% and 90.7% in contralateral and randomly matched controls, respectively, versus 91.6% among all deceased donor transplants in the Scientific Registry of Transplant Recipients.Conclusions
Routine use of biopsies could lead to unnecessary kidney discards. 相似文献107.

Epilepsy surgery is safe and effective treatment in children who fail to respond to antiepileptic medications. After failure of two appropriate antiepileptic medications, chances that the child will become seizure free with more or different medications is <5 %, and she should be diagnosed with “refractory epilepsy”. A consideration for surgical candidacy should be given to all children who fulfill the definition of refractory epilepsy. In appropriately selected children, epilepsy surgery offers a high chance of seizure freedom without incurring any new post-operative neurological deficits. No age is bar to epilepsy surgery. Even infants can safely have epilepsy surgery if they are surgical candidates. For most children, who are surgical candidates, a good history and physical examination, video EEG evaluation, and a high quality brain MRI are sufficient to make surgical decision. These tools are increasingly available all over the world. Better education of families, Pediatricians, Pediatric Neurologists and community care-givers is necessary to salvage children early from mortality and morbidity of untreated, sometimes life long, epilepsy. 相似文献

Candidate gene and genome-wide association studies (GWAS) represent two complementary approaches to uncovering genetic contributions to common diseases. We systematically reviewed the contributions of these approaches to our knowledge of genetic associations with cancer risk by analyzing the data in the Cancer Genome-wide Association and Meta Analyses database (Cancer GAMAdb). The database catalogs studies published since January 1, 2000, by study and cancer type. In all, we found that meta-analyses and pooled analyses of candidate genes reported 349 statistically significant associations and GWAS reported 269, for a total of 577 unique associations. Only 41 (7.1%) associations were reported in both candidate gene meta-analyses and GWAS, usually with similar effect sizes. When considering only noteworthy associations (defined as those with false-positive report probabilities ≤0.2) and accounting for indirect overlap, we found 202 associations, with 27 of those appearing in both meta-analyses and GWAS. Our findings suggest that meta-analyses of well-conducted candidate gene studies may continue to add to our understanding of the genetic associations in the post-GWAS era. 相似文献

Paneth cells are long-lived secretory cells that reside in the base of the crypts of Lieberkühn of the small intestine. They produce an arsenal of molecules that are involved in numerous biological processes, ranging from the control of gut microbial populations to supporting the intestinal stem cell niche. Because of these important functions, Paneth cell abnormalities are becoming implicated in a variety of disease processes. As such, it is necessary to establish parameters that will allow for the comprehensive study of Paneth cells in health and disease. In this addendum, we highlight critical design aspects involved in the study of Paneth cells and their downstream effects on the intestinal microbiota. The importance of this approach is demonstrated by our recent findings that Nod2 does not regulate mouse Paneth cell antimicrobial function, in contrast to previous reports. This work defines key issues to consider when studying Paneth cells in mouse systems. 相似文献
