Conclusions Although there was moderate-to-strong agreement between child/parent reports of concussion symptoms, discrepancies in individual cognitive symptom reports exist, in both children and adolescents. Therefore, collection of parent scales may provide useful information when tracking cognitive symptoms in adolescent patients, who may under-report or under-recognize cognitive deficits.

There is a need to identify and quantify mesenchymal stromal cells (MSCs) in human bone marrow aspirate concentrate (BMAC) source tissues, but current methods to do so were established in cultured cell populations. Given that surface marker and gene expression change in cultured cells, it is doubtful that these strategies are valid to quantify MSCs in fresh BMAC.

To establish the presence, quantity, and heterogeneity of BMAC-derived MSCs in minimally manipulated BMAC using currently available strategies.

Descriptive laboratory study.

Five published strategies to identify MSCs were compared for suitability and efficiency to quantify clinical-grade BMAC-MSCs and cultured MSCs at the single cell transcriptome level on BMAC samples being used clinically from 15 orthopaedic patients and on 1 cultured MSC sample. Strategies included (1) the guidelines by the International Society for Cellular Therapy (ISCT), (2) CD271 expression, (3) the Ghazanfari et al transcriptional profile, (4) the Jia et al transcriptded. Until then, injected minimally manipulated MSC doses should be reported as rough estimates or as unknown.

This study demonstrated that improved strategies to quantify MSC concentrations in BMAC for clinical applications are urgently needed. Until then, injected minimally manipulated MSC doses should be reported as rough estimates or as unknown.Duloxetine, a selective serotonin-norepinephrine reuptake inhibitor, is currently recommended to use in the treatment of chronic painful disorders such as fibromyalgia, chronic musculoskeletal pain and diabetic peripheral neuropathy. We previously demonstrated that bone morphogenetic protein-4 (BMP-4) stimulates osteoprotegerin (OPG) production in osteoblast-like MC3T3-E1 cells, and that p70 S6 kinase positively regulates the OPG synthesis. The present study is aimed to investigate the effect of duloxetine on BMP-4-stimulated OPG synthesis in these cells. Duloxetine dose-dependently suppressed the OPG release stimulated by BMP-4. Fluvoxamine, a selective serotonin reuptake inhibitor (SSRI), reduced the BMP-4-stimulated OPG release, whereas a selective and specific norepinephrine reuptake inhibitor, reboxetine failed to affect the OPG release. In addition, another SSRI sertraline also inhibited the BMP-4-stimulated OPG release. On the other hand, siRNA of SMAD1 reduced the OPG release stimulated by BMP-4, indicating the involvement of SMAD1/5/8 pathway in the OPG release. Rapamycin, an inhibitor of mTOR, reduced the BMP-4-stimulated p70 S6 kinase phosphorylation, and compound C, an inhibitor of BMP type I receptor, suppressed the SMAD1/5/8 phosphorylation stimulated by BMP-4. I-BRD9 order Duloxetine did not affect the BMP-4-induced phosphorylation of p70 S6 kinase but suppressed the SMAD1/5/8 phosphorylation. Both fluvoxamine and sertraline also inhibited the BMP-4-elicited phosphorylation of SMAD1/5/8. These results strongly suggest that duloxetine suppresses the BMP-4-stimulated OPG release via inhibition of the Smad1/5/8 signaling pathway from osteoblasts.

The practice of evidence-based medicine relies on objective data to guide clinical decision-making with specific statistical thresholds conveying study significance.

To determine the utility of applying the fragility index (FI) and the fragility quotient (FQ) analysis to randomized controlled trials (RCTs) evaluating the utilization of platelet-rich plasma (PRP) in rotator cuff repairs (RCRs).

Systematic review and meta-analysis.

RCTs pertaining to the utilization of PRP in surgical RCRs published in 13 peer-reviewed journals from 2000 to 2020 were evaluated. The FI was determined by manipulating each reported outcome event until a reversal of significance was appreciated. The associated FQ was determined by dividing the FI by the sample size.

Of the 9746 studies screened, 19 RCTs were ultimately included for analysis. The overall FI incorporating all 19 RCTs was only 4, suggesting that the reversal of only 4 events is required to change study significance. The associated FQ was determined as 0.092. Of the 43 outcome events reporting lost to follow-up data, 13 (30.2%) represented lost to follow-up >4.

Our analysis suggests that RCTs evaluating PRP for surgical RCRs may lack statistical stability with only a few outcome events required to alter trial significance. Therefore, we recommend the reporting of an FI and an FQ in conjunction with

value analysis to carefully interpret the integrity of statistical stability in future comparative trials.

Clinical decisions are often informed by statistically significant results. Thus, a true understanding of the robustness of the statistical findings informing clinical decision-making is of critical importance.

For most medical students, clerkship represents a transitional phase into the 'real world' of medicine. This transition is often accompanied by significant mental stressors, burnout, and empathy decline. Educator led resilience curricula designed to support students during this critical period often focus on teaching generalized strategies to promote wellness and lack the student input and perspective in their development. Thus, they may be of minimal value when learners are faced with acute moments of challenge and distress in their day-to-day work. The following project seeks to provide an insider view on the experience, interpretation, and response to these moments of challenge and distress from the frontline perspective of clinical clerks.

Using collaborative autoethnography, two medical students documented 85 reflections on their emerging professional identity over the course of a core clerkship year. A narrative analysis was conducted iteratively in partnership with a staff internist and a medical education researcher experienced in autoethnography, allowing for robust multi-perspective input.
