nts, the reason was typically a change in patient condition. Products cryopreserved for patient reasons were significantly associated with inferior OS in multivariate analysis (HR, 0.65; 95% CI, 0.44 to 0.96; P = .029). We conclude that cryopreservation is associated with slower engraftment of PBSC grafts, which may be associated with inferior transplantation outcomes in some patient populations. However, the small numbers in the cryopreserved BM cohort and the lack of information on the reason for cryopreservation in all patients suggests that these data should be interpreted with caution, particularly in the context of the risks associated with unexpected loss of a graft during the pandemic. Future analyses addressing outcomes when cryopreservation is universally applied are urgently required.The objective of this scoping review was to identify and characterize studies examining the effect of nutrition management interventions and effectiveness of medical nutrition therapy to improve nutrition-related outcomes in children and adolescents with type 1 diabetes. An in-depth electronic search was conducted by a medical librarian in six databases Medline, Embase, Cochrane Central Register of Controlled Trials, PsycINFO, The Cumulative Index to Nursing and Allied Health Literature, and Web of Science Core Collection. The literature search resulted in 5,122 records, and five records were identified through hand search. Of these 5,127 records, 22 articles and eight systematic reviews met our inclusion criteria. An equal number of the studies were experimental (ie, randomized or nonrandomized controlled trials, or noncontrolled trials) (n = 11) and observational (cohort, case-control, and cross-sectional) (n = 11) with the remaining studies being systematic reviews/meta-analyses (n = 8). Most of these studies were conducted in United States or Europe. Based on this scoping review, the majority of studies focus on either carbohydrate counting or evaluation of dietary intake patterns with little emphasis on tailored patient education/counseling services specifically designed to meet a young child's or his/her family's individual needs. Indeed, only four studies in this scoping review used dietary counseling and/or medical nutrition therapy. As such, there remains a significant gap in the literature as it relates to the efficacy and long-term management implications of tailored nutrition interventions in young children with type 1 diabetes.Biguanides are a class of antidiabetic drugs that includes phenformin and metformin; however, the former was withdrawn from approval in many countries due to its toxicity. Findings from retrospective epidemiological studies in diabetic populations and preclinical laboratory models have demonstrated that biguanides possess antitumor activities that suggest their repurposing for cancer prevention and treatment. However, a better understanding of how these biguanides behave as antitumor agents is needed to guide their improved applications in cancer therapy, spurring increased interest in their pharmacology. Here, we present evidence for proposed mechanisms of action related to their antitumor activity, including their effects on central carbon metabolism in cancer cells and immune-modulating activity, and then review progress on biguanide repurposing in cancer therapeutics and the possible re-evaluation of phenformin as a cancer therapeutic agent. Pelvic lymph node dissection (PLND) is the most reliable procedure for lymph node staging. However, the therapeutic benefit remains unproven; although most radical prostatectomies at academic centers are accompanied by PLND, there is no consensus regarding the optimal anatomical extent of PLND. To evaluate whether extended PLND results in a lower biochemical recurrence rate. We conducted a single-center randomized trial. Patients, enrolled between October 2011 and March 2017, were scheduled to undergo radical prostatectomy and PLND. Patients were assigned to limited or extended PLND by cluster randomization. Specifically, surgeons were randomized to perform limited or extended PLND for 3-mo periods. Randomization to limited (external iliac nodes) or extended (external iliac, obturator fossa and hypogastric nodes) PLND. The primary endpoint was the rate of biochemical recurrence. Of 1440 patients included in the final analysis, 700 were randomized to limited PLND and 740 to extended PLND. The mediated and extended dissection of lymph nodes in the pelvis. This study is registered on ClinicalTrials.gov as NCT01407263. In this clinical trial we did not find a difference in the rate of biochemical recurrence of prostate cancer between limited and extended dissection of lymph nodes in the pelvis. This study is registered on ClinicalTrials.gov as NCT01407263. The Coronavirus 2019 (COVID-19) pandemic caused a considerable mortality in long-term care facilities (LTCFs), including residential care setting and nursing homes. This study aimed to estimate COVID-19 incidence and mortality in residential care facilities and to compare them with those recorded in nursing homes. Nationwide observational study conducted by French health authorities. Since March 1, 2020, all LTCFs in France reported all COVID-19 cases and COVID-19-related deaths among their residents. Possible cases were those with COVID-19-related symptoms without laboratory confirmation and confirmed cases those with a reverse transcriptase polymerase chain reaction test or serology positive for SARS-CoV-2. We included facilities with at least 1 confirmed case of COVID-19 and estimated the cumulative incidence of COVID-19 cases and mortality due to COVID-19 reported until June 30, 2020, using the maximum bed capacity as a denominator. Of the 2288 residential care facilities, 310 (14%) and, of the 7688 nursing homes, 3110 (40%) reported COVID-19 cases among residents (P<.001). The cumulative incidence of COVID-19 was significantly lower in residential care facilities as compared with nursing homes (1.10 vs 9.97 per 100 beds, P<.001). Mortality due to COVID-19 was also lower in residential care facilities compared with nursing homes (0.07 vs 1.29 per 100 beds, P<.001). https://www.selleckchem.com/products/Cisplatin.html Case fatality was lower in residential care facilities (6.49% vs 12.93%, P<.001). French residential care facilities experienced a much lower burden from COVID-19 than nursing homes. Our findings may inform the implementation of better infection control practices in these settings.
