We find that it is optimal to vaccinate younger individuals to minimize new infections, whereas it is optimal to vaccinate older individuals to minimize deaths, life years lost, or QALYs lost due to death. Numerical simulations show that the allocations resulting from our conditions match those found using much more computationally expensive algorithms such as exhaustive search. Sensitivity analysis on key parameters indicates that the optimal allocation is robust to changes in parameter values. The simple conditions we develop provide a useful means of informing vaccine allocation decisions for communicable diseases.The history of ketamine begins in 1962, when Calvin Stevens of the pharmaceutical laboratory Parke-Davis synthesizes it from phencyclidine, a molecule with psychodysleptic, hallucinogenic and dissociative properties. Following the first administration of ketamine to humans in 1964 in Jackson prison (Michigan, USA), its dissociative effects associated with short anaesthesia were reported, and a patent for its human use was filed in 1966. In the 1990s, the discovery of opioid-induced hyperalgesia sparked interest in ketamine as an analgesic. In recent years, the human use of ketamine, and in particular its esketamine enantiomer, has shifted towards the treatment of depression. The first cases of ketamine abuse were reported in 1992 in France, leading to special surveillance by the health authorities, and its inclusion in the list of narcotic drugs in 1997. Today, ketamine has become an attractive substance for recreational use, gradually emerging from alternative techno circles to spread to more commercial party scenes. These elements represent a public health concern, associated with the risk of developing new chemically synthesized analogues, the harmful effects of which are still little known.

The Sterilization Unit of the Narbonne Hospital Center (France) has decided to embark on a process of NF EN ISO 9001 2015 certification. The objective is to describe how the working group has appropriated the provisions relating to staff training in order to build a skills development plan for its Sterilization agents.

A multi-professional working group has been set up. After a preliminary inventory, an inventory of skills needs, expectations of the agents, available means, and a bibliographical research, the group drew up a training plan with the support of a quality engineer from the Hospital Centre. The training plan was validated by a review of the management of the establishment.

Several teaching aids were chosen a serious game developed by the working group, the planning of instrumentation sessions, quality meetings and feedback committees. The principle of transdisciplinarity and recourse to multi-professional exchanges is the common thread in the elaboration of the training plan.

The use of the selected materials is formalised in the form of a skills development plan indexed in the institution's quality management system. The application of the requirements of the ISO 9001 standard in terms of training in our Sterilization quality management system enables risk control and continuous improvement of the training plan to comply with technical and regulatory changes in the profession.

Since ferroptosis discovery, it has become a new target for antitumor therapy actively explored by researchers. In this review, we provide an overview of the known mechanisms that regulate the sensitivity of cancer cells to ferroptosis and the research progress of ferroptosis-related drugs (western medicine, traditional Chinese medicine, and nanomedicine), as well as the relationship between ferroptosis and cancer treatment, tumor drug resistance, and antitumor immunotherapy.Somatic gain-of-function mutations within estrogen receptor alpha (ERα) are highly associated with hormone therapy resistance in breast cancer. However, current understanding of abnormal activity of ERα mutants and their relevant targeted intervention is still very limited. iCRT3 antagonist Herein, we developed a new, real-time, and reliably Gaussia luciferase-based protein-fragment complementation assay (GLPCA) for evaluating ERα mutants activities. We found that, compared with ER WT, ERα mutants (Y537S/N and D538G) exhibit high ligand-independent activity, suggesting the gain-of-function phenotype of these ERα mutants. Notably, Y537S, the most common ERα mutant type, has the highest intrinsic activation. We then collected and screened a natural product library for potential ERα antagonists via GLPCA and identified celastrol and gambogic acid as new antagonists of the ERα Y537S mutant. Moreover, interactions between these two compounds and the ERα Y537S mutant were confirmed by molecular docking and cellular thermal shift assay. Importantly, we further demonstrated that celastrol and gambogic acid exhibit synergistic antiproliferative and pro-apoptotic effects when combined with an approved CDK4/6 inhibitor abemaciclib in breast cancer cells expressing ERα Y537S. In summary, GLPCA provides a powerful platform for exploring innovative functional biology and drug discovery of antagonists targeting ERα mutants.The coronavirus disease 2019 (COVID-19) pandemic has caused the most devasting social and economic impact of this century. The current pandemic will end only after a safe, effective vaccine becomes available and protective herd immunity has been achieved through vaccination. The key parameter to gauge protective immunity is neutralizing antibody levels. Thus, reliable serology testing is essential to diagnose whether an individual has been previously infected, as a large proportion of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections is asymptomatic. For both naturally infected and vaccinated individuals, it is critical to monitor their neutralizing antibody titers over time. This is because, when neutralizing antibody levels wane below a threshold which remains to be determined, they become vulnerable to reinfection. Due to the importance of serology testing, academia and industry have developed different platforms for serological diagnosis, many of which have achieved the Food and Drug Administration (FDA) Emergency Use Authorizations (EUA). Here we summarize the status of COVID-19 serology testing, discuss challenges, and provide future directions for improvement.

To examine the impact of a new approach, Get SET Early, on the rates of early autism spectrum disorder (ASD) detection and factors that influence the screen-evaluate-treat chain.

After attending Get SET Early training, 203 pediatricians administered 57 603 total screens using the Communication and Symbolic Behavior Scales Infant-Toddler Checklist at 12-, 18-, and 24-month well-baby examinations, and parents designated presence or absence of concern. For screen-positive toddlers, pediatricians specified if the child was being referred for evaluation, and if not, why not.

Collapsed across ages, toddlers were evaluated and referred for treatment at a median age of 19months, and those screened at 12months (59.4% of sample) by 15months. Pediatricians referred one-third of screen-positive toddlers for evaluation, citing lack of confidence in the accuracy of screen-positive results as the primary reason for nonreferral. If a parent expressed concerns, referral probability doubled, and the rate of an ASD diagnosis increased by 37%. Of 897 toddlers evaluated, almost one-half were diagnosed as ASD, translating into an ASD prevalence of 1%.

The Get SET Early model was effective at detecting ASD and initiating very early treatment. Results also underscored the need for change in early identification approaches to formally operationalize and incorporate pediatrician judgment and level of parent concern into the process.

To characterize the clinical, laboratory, histologic, molecular features, and outcome of gene-confirmed progressive familial intrahepatic cholestasis (PFIC) 1-3 among Arabs and to evaluate for "genotype-phenotype" correlations.

We retrospectively reviewed charts of 65 children (ATP8B1 defect=5, ABCB11=35, ABCB4=25) who presented between 2008 and 2019 with cholestasis. The clinical phenotype of a disease was categorized based on response of cholestasis and itching to ursodeoxycholic acid and ultimate outcome, into mild (complete response), intermediate (partial response, nonprogressive), and severe (progression to end-stage liver disease).

Overall, 27 different mutations were identified (ATP8B1, n=5; ABCB11, n=11; ABCB4, n=11), comprising 10 novel ones. Six patients with heterozygous missense mutations (ATP8B1, n=2; ABCB11, n=4) had transient cholestasis. Of the remaining 3 patients with PFIC1, 2 developed severe phenotype (splicing and frameshift mutations). Of the remaining 31 patients with PFIC2, 25 dherapy.

The efficacy of dendritic cell vaccine to treat glioblastoma remained elusive and therefore we conducted a meta-analysis to explore the influence of dendritic cell vaccine on treatment efficacy of glioblastoma.

PubMed, EMbase, Web of science, EBSCO and Cochrane library databases have been searched through October 2020, and we included randomized controlled trials (RCTs) assessing the efficacy of dendritic cell vaccine for glioblastoma.

Four RCTs and 267 patients were included in the meta-analysis. Compared to control group for glioblastoma, dendritic cell vaccine demonstrated no obvious impact on overall survival (HR=0.59; 95% CI=0.34 to 1.04; P=0.07), progression-free survival (PFS, HR=0.72; 95% CI=0.52 to 1.00; P=0.05), nervous system disorders (OR=0.61; 95% CI=0.29 to 1.29; P=0.20), or adverse events (OR=1.44; 95% CI=0.82 to 2.50; P=0.20).

Dendritic cell vaccine may be not effective to treat glioblastoma.

To assess the incidence and analyze the risk factors of postoperative spinal epidural hematoma (SEH) after transforaminal lumbar interbody fusion (TLIF) surgery, in order to provide a solution for reducing the occurrence of postoperative SEH after TLIF.

A total of 3717 patients who were performed TLIF surgery in the Orthopedics department of our hospital from January 2010 to March 2020 were included. Patients who had reoperations due to postoperative SEH were selected as the SEH group. The control group was randomly selected from patients without reoperations with the ratio of 31 compared to the SEH group. The basic information, preoperative examination and surgical information of the patients were collected through the hospital medical record system, and the statistics were processed through SPSS 22.0 software.

(1) Among the 3717 patients who underwent TLIF surgery in our hospital in the past 10 years, 46 had secondary surgeries, with a total incidence of 1.24%. 12 cases had secondary surgeries due to postoperative SEH, with an incidence of 0.
