Organ transplantation is an innovative field that was pioneered in the middle of the last century with the development of surgical techniques, advances in the understanding of immunological processes that cause rejection, introduction of drugs to prevent rejection and improved methods for organ preservation. In Israel, the first heart transplantation and kidney transplantation were performed in the mid-1960's followed by pancreas, lung and liver transplantation that were conducted for the first time in the late 1980's and early 1990's. The significant change that has led to an increase in the number of transplants in Israel and rising success rates after transplant has occurred with the introduction of the new generation of anti-rejection drugs, Cyclosporine and subsequently Tacrolimus (Prograf ®). Another milestone was the founding of The National Transplant Center in 1994. This led to the formation of national transplant candidate lists for each organ, the establishment of professional committees that determine organ allocation policy and the creation of a governmental ethics committee to oversee the performance of live-donor transplantation. In 2008, about a month before the signing of the Istanbul Declaration, the Transplantation Law was enacted to regulate organ transplantation in Israel, which included clauses restricting organ trade in the spirit of the Istanbul Declaration. These measures increased the number of transplants performed in Israel and significantly reduced the number of transplants of Israelis abroad. The establishment of Matanat Chaim Organization in 2012 is another milestone that has led to a significant increase in the number of kidney transplants, most of which are currently performed from altruistic donations. However, today there is still a shortage of organs for transplantation from deceased donors and there is a long way to go to close the gap between organ need and supply. This review will indicate the introduction of the first transplants performed in Israel and the measures undertaken to increase the number of transplants. In addition, the review will note the laws and regulations of organ allocation.

Background Aims: Patients with hepatocellular carcinoma (HCC) meeting UNOS-downstaging (DS) criteria have excellent post-liver transplantation (LT) outcomes. Studies on HCC beyond UNOS-DS criteria ("All-comers" (AC)) have been limited by small sample size and short follow-up time, prompting this analysis.
Approach Results: 326 patients meeting UNOS-DS and 190 meeting AC criteria from 9 LT centers across 5 UNOS regions were enrolled from 2015 to 2023 and prospectively followed.

Background: During orthotopic liver transplantation, allograft reperfusion is a dynamic point in the operation and often requires vasoactive medications and blood transfusions. Normothermic machine perfusion (NMP) of liver allografts has emerged to increase the number of transplantable organs and may have utility during donation after circulatory death (DCD) liver transplantation in reducing transfusion burden and vasoactive medication requirements.
Methods: This is a single-center retrospective study involving 226 DCD liver transplant recipients who received an allograft transported with NMP (DCD-NMP group) or with static cold storage (DCD-SCS group).

As a commonly employed method for analyzing time-to-event data involving functional predictors, the functional Cox model assumes a linear relationship between the functional principal component (FPC) scores of the functional predictors and the hazard rates. However, in practical scenarios, such as our study on the survival time of kidney transplant recipients, this assumption often fails to hold. To address this limitation, we introduce a class of high-dimensional partially linear functional Cox models, which accommodates the non-linear effects of functional predictors on the response and allows for diverging numbers of scalar predictors and FPCs as the sample size increases.

Purpose: Bone expansion is one of the quickest, simplest, and most reliable methods of alveolar ridge augmentation for implant placement. This systematic review is designed to investigate the outcomes of the bone expansion technique for horizontal ridge augmentation.
Methods: The protocol of study has been prospectively registered into PROSPERO (CRD42023414686).

Background: The management of pediatric acute myeloid leukemia (AML) is based on the prognostic risk classification of initial leukemia. Targeted next-generation sequencing (NGS) is a reliable method used to identify recurrently mutated genes of pediatric AML and associated prognosis.
Methods: In this study, we retrospectively evaluated the prognostic, and therapeutic utility of a targeted NGS panel covering twenty-five genes, in 21 children with de novo and 8 with relapsed or secondary AML.
