Challenges inherent to community engagement work emerged early in the process are discussed.
 
  HCS will show how community engagement can support the implementation of evidence-based practices for addressing the opioid crisis in highly impacted communities. Findings from this study have the potential to provide communities across the country with an evidence-based approach to address their local opioid crisis; advance community engaged research; and contribute to the implementation, sustainability, and adoption of evidence-based practices.

Decidual immune cells (DICs)-mediated cytokine microenvironment is involved in pregnancy and regulated by many microRNAs, but whether microRNA-146a-5p (miR-146a) regulate the decidual cytokine microenvironment and the potential mechanisms in unexplained SA pathogenesis have rarely been reported. In this study, the levels of cytokines and miR-146a in healthy and unexplained SA deciduae were first investigated, and the correlation between them was analyzed. Then, the effect of miR-146a inhibitor on cytokines was assessed in healthy deciduae-derived DICs. Third, the downstream targets and related molecular mechanisms of miR-146a were analyzed by bioinformatics, and the levels of the predicted targets in deciduae were assessed, followed by the correlation analysis between the levels of miR-146a and the targets. Finally, the effect of miR-146a on the predicted targets and inflammatory cytokines was validated in unexplained SA deciduae-derived DICs. As a result, decreased miR-146a correlated with the cytokine disorder in unexplained SA deciduae, and inhibition of miR-146a promoted pro-inflammatory response in healthy deciduae-derived DICs. One hundred four target genes and related molecular mechanisms of miR-146a were predicted, among which the toll-like receptor (TLR) pathway might be associated with the decidual cytokine regulation. Upregulation of miR-146a inhibited the expression of the predicted molecules enriched in the TLR pathway and improved the cytokine disorder in unexplained SA deciduae-derived DICs. Collectively, miR-146a improves the decidual cytokine microenvironment by regulating the TLR pathway in unexplained SA, providing novel potential targets for further therapeutic research.Chimeric antigen receptor T (CAR-T) cell therapy is a breakthrough in cancer treatment. With the widespread use of this therapy, increasing evidence is available that CAR-T cell therapy is associated with acute kidney injury (AKI). Nephrologists need to understand the potential nephrotoxicity arising from CAR-T cell therapy. Determining the cause of AKI is a key factor of clinical management. This review focuses on the clinical use of CAR-T cell therapy and the cause and outcomes of nephrotoxicity with its use.  https://www.selleckchem.com/products/tideglusib.html  We also provide clinical suggestions for clinicians towards both better diagnosis and management of AKI in those receiving CAR-T cell therapy.A classical experiment of auditory stream segregation is revisited, reconceptualising perceptual ambiguity in terms of affordances and musical engagement. Specifically, three experiments are reported that investigate how listeners' perception of auditory sequences change dynamically depending on emotional context. The experiments show that listeners adapt their attention to higher or lower pitched streams (Experiments 1 and 2) and the degree of auditory stream integration or segregation (Experiment 3) in accordance with the presented emotional context. Participants with and without formal musical training show this influence, although to differing degrees (Experiment 2). Contributing evidence to the literature on interactions between emotion and cognition, these experiments demonstrate how emotion is an intrinsic part of music perception and not merely a product of the listening experience.
  Current predictive biomarkers for PD-1 (programmed cell death protein 1)/PD-L1 (programmed death-ligand 1)-directed immunotherapy in non-small cell lung cancer (NSCLC) mostly focus on features of tumour cells. However, the tumour microenvironment and immune context are expected to play major roles in governing therapy response. Against this background, we set out to apply context-sensitive feature selection and machine learning approaches on expression profiles of immune-related genes in diagnostic biopsies of patients with stage IV NSCLC.
 
  RNA expression levels were determined using the NanoString nCounter platform in formalin-fixed paraffin-embedded tumour biopsies obtained during the diagnostic workup of stage IV NSCLC from two thoracic oncology centres. A 770-gene panel covering immune-related genes and control genes was used. We applied supervised machine learning methods for feature selection and generation of predictive models.
 
  Feature selection and model creation were based on a training cohort o-L1-directed immunotherapy in NSCLC.
  Pneumocystis jirovecii pneumonia (PJP) is a life-threatening opportunistic infection. Prophylaxis is recommended for patients with malignancies and trimethoprim-sulfamethoxazole (TMP-SMX) is the recommended first-line agent. Many paediatric patients receive second-line agents due to perceived adverse reactions from TMP-SMX.
 
  The objective of the study is to determine the risk of PJP in patients receiving TMP-SMX vs. second-line medications for prophylaxis.
 
  We conducted a retrospective, single centre, case-control study of paediatric oncology patients. Cases included children diagnosed with PJP by microscopy between 2000 and 2018 while being treated for a malignancy. Controls were matched by age, oncologic diagnosis, treatment protocol, phase of treatment and oncologic diagnosis date. For each case, up to 5 controls were randomly selected. The index date was the date of the PJP diagnosis for cases and the equivalent dummy date for controls.
 
  Eleven cases with PJP were identified and matched with 50 controls. Six (55%) cases and 42 (84%) controls were on prophylaxis with TMP-SMX. The remaining patients received inhaled pentamidine (3 cases, 4 controls), dapsone (2 cases, 3 controls), or atovaquone (1 control). Myelosuppression was the most common reason to stop TMP-SMX. Cases with PJP were less likely to have been taking TMP-SMX in the 3 months before diagnosis when compared with controls (odds ratio 0.15, 95% confidence interval 0.01-0.97, p=0.02).
 
  TMP-SMX prophylaxis was associated with a lower risk of developing PJP compared with second-line treatments. Although alternate agents may be required in certain situations, efforts should be made to rechallenge with TMP-SMX when possible.
