    Altogether, our study suggests that, in the patient-derived α-synuclein aggregates-injected mouse model and within the selected time frame, the disease is not „transmitted“ through the bloodstream.Fragile X syndrome (FXS) is the most common form of intellectual disability that arises from the dysfunction of a single gene-Fmr1. The main neuroanatomical correlate of FXS is elevated dendritic spine density on cortical pyramidal neurons, which has been modeled in Fmr1-/Y mice. However, the cell-autonomous contribution of Fmr1 on cortical dendritic spine density has not been assessed. Even less is known about the role of Fmr1 in heterozygous female mosaic mice, which are a putative model for human Fmr1 full mutation carriers (i.e., are heterozygous for the full Fmr1-silencing mutation). In this neuroanatomical study, spine density in cortical pyramidal neurons of Fmr1+/- and Fmr1-/Y mice was studied at multiple subcellular compartments, layers, and brain regions. Spine density in Fmr1+/- mice is higher than WT but lower than Fmr1-/Y. Not all subcellular compartments in layer V Fmr1+/- and Fmr1-/Y cortical pyramidal neurons are equally affected the apical dendrite, a key subcellular compartment, is principally affected over basal dendrites. link= Epigenetic signaling inhibitor Within apical dendrites, spine density is differentially affected across branch orders. Finally, identification of FMRP-positive and FMRP-negative neurons within Fmr1+/- permitted the study of the cell-autonomous effect of Fmr1 on spine density. Surprisingly, layer V cortical pyramidal spine density between FMRP-positive and FMRP-negative neurons does not differ, suggesting that the regulation of the primary neuroanatomical defect of FXS-elevated spine density-is non-cell-autonomous.The mechanical environment of the joint during dynamic activity plays a significant role in osteoarthritis processes. Understanding how the magnitude, pattern and duration of joint-specific loading features contribute to osteoarthritis progression and response to treatment is a topic of on-going relevance. This narrative review synthesizes evidence from recent papers that have contributed to knowledge related to three identified emerging subthemes 1) the role of the joint mechanical environment in osteoarthritis pathogenesis, 2) joint biomechanics as an outcome to arthroplasty treatment of osteoarthritis, and 3) methodological trends for advancing our knowledge of the role of biomechanics in osteoarthritis. Rather than provide an exhaustive review of a broad area of research, we have focused on evidence this year related to these subthemes. link2 New research this year has indicated significant interest in using biomechanics investigations to understand structural vs clinical progression of osteoarthritis, the role and interaction in the three-dimensional loading environment of the joint, and the contribution of muscle activation and forces to osteoarthritis progression. There is ongoing interest in understanding how patient variability with respect to gait biomechanics influences arthroplasty surgery outcomes, and subgroup analyses have provided evidence for the potential utility in tailored treatment approaches. Finally, we are seeing a growing trend in the application of translational biomechanics tools such as wearable inertial measurement units for improved integration of biomechanics into clinical decision-making and outcomes assessment for osteoarthritis.

    Although the achievement of adequate analgesia is critical to patient comfort and recovery following orthopedic procedures, no standard protocol exists to dictate the appropriate duration and quantity of narcotic prescription in the postoperative period. Epigenetic signaling inhibitor Therefore, the purpose of this survey was to determine patterns of opioid prescribing among orthopedic shoulder and elbow providers.

    In March 2020, a survey was distributed through a LISTSERV to 989 members of the American Shoulder and Elbow Surgeons orthopedic society. Survey recipients were asked to describe their personal and practice characteristics. Additionally, they were asked to list their 3 most commonly performed procedures and, for each operation, to list which narcotic pain medication they most commonly prescribe postoperatively, along with the corresponding number of tablets typically given. Similarly, respondents were asked to record frequently recommended alternative strategies for postoperative pain control, factors influencing the respondevidence-based opioid prescription guidelines for surgical procedures on the shoulder and elbow. In addition to recommending safe, procedure-specific opioid dosages and standardizing pain management strategies, these guidelines should include effective methods of educating both providers and patients regarding the use of opioid medication.

    Cutibacterium acnes is one of the major pathogens responsible for infection after shoulder surgery. Surgical dissection of the dermis may expose C acnes from sebum-producing hair follicles. link2 Because of contact with the surgeon’s gloves and instruments, further spread occurs throughout the surgical field. The purpose of this study was to determine whether subcutaneous tissue disinfection could reduce the C acnes culture rate in primary open shoulder surgery.

    All patients eligible for primary open shoulder surgery by a deltopectoral approach were prospectively enrolled in our 2-arm, randomized, single-blinded clinical trial. In all patients, a skin swab of the operative field was taken prior to standard surgical skin preparation. After exposure of the deltoid fascia, the disinfection group received an additional preparation of the subcutaneous layer with povidone-iodine solution. Once the proximal humerus was completely exposed, 5 swabs from different sites were taken for microbiological examination accordin owing to this practice.

    Disinfection of the subcutaneous tissue significantly reduced the C acnes culture rate during primary open shoulder surgery. We highly recommend this simple step as an adjunct to the current surgical practice to limit iatrogenic contamination of the surgical field. Future studies may observe a reduction in postoperative shoulder infection owing to this practice.

    Hematoma formation and the need for blood transfusions are commonly reported complications after shoulder arthroplasty. Tranexamic acid (TXA) has been widely used in hip and knee arthroplasty to decrease perioperative blood loss. The role of TXA is still being established in shoulder arthroplasty.

    We conducted a double-blind randomized controlled trial comparing intravenous TXA vs. placebo in 60 patients undergoing primary anatomic or reverse shoulder arthroplasty. Of these patients, 29 received a placebo whereas 31 received a single dose of 2 g of intravenous TXA. Epigenetic signaling inhibitor Patient demographic characteristics, as well as drain tube output, blood loss, hematoma formation, transfusion requirement, length of hospital stay, and pain score, were recorded. Patients were followed up for 12 weeks to assess for complications.

    Patients who received TXA had a lower drain tube output at all time points 41 mL vs. 133 mL at 6 hours, 75 mL vs. link3 179 mL at 12 hours, and 94 mL vs. 226 mL at 24 hours (P < .001 for all). They alsin primary anatomic and reverse arthroplasty of the shoulder. No differences were detected in the occurrence of complications, need for transfusion, pain score, or length of hospital stay. With the mounting evidence now available, patients undergoing elective primary shoulder arthroplasty should be given intravenous TXA to decrease perioperative blood loss.

    Immune checkpoint programmed death-ligand 1 (PDL-1) inhibitor therapy has shown response in metastatic muscle invasive bladder cancer (MIBC). We evaluated the safety and tolerability of atezolizumab (anti-PDL-1) in combination with trimodal therapy (TMT) in patients with localized MIBC.

    A prospective non-randomized phase I study using a 3+3 design was conducted in patients with localized MIBC (T2-T4a N0M0) treated on a bladder preservation program. Following trans-urethral resection of bladder tumor, patients received concurrent radiotherapy at a fixed dose of 50 Gy/20 fractions, gemcitabine (100 mg/m

    , IV once weekly x 4) and atezolizumab (1200 mg IV every 3 weeks x 16 cycles). Primary endpoint was safety/toxicity profile.

    Between May 2018 and March 2019, 8 patients (6 males and 2 females) were enrolled. The first 5 patients received atezolizumab at 1200 mg, three of whom developed grade 3 side effects (2 of them dose limiting toxicity). link3 Atezolizumab dose was reduced to 840 mg for 3 additional patients. The study was terminated due to the presence of three grade 3 adverse events (2 of them dose limiting toxicity) despite the reduced atezolizumab dose. Gastro-intestinal (GI) events were the main toxicity. No grade 4-5 adverse effects were observed.

    Concurrent administration of atezolizumab with concomitant hypofractionated radiotherapy and gemcitabine appears to be associated with unacceptable GI toxicity. While numbers studied are small, our results suggest considerable caution with its concurrent use with trimodal therapy for MIBC.

    Radiation-induced optic neuropathy (RION) is a rare, yet severe complication following radiation therapy for brain, head and neck, or skull-base tumors. Although several risk factors, such as age, metabolic syndrome, and delivered dose, have been identified, we aimed at expanding the understanding of the mechanisms of interplay regarding dosimetry and patient variables leading to the onset of RION with a focus on proton therapy.

    In this retrospective study, we have investigated proton-specific risk factors by comparing common phenomenological normal tissue complication probability models with a multivariate analysis that includes clinical features on a cohort of patients with skull-base and head and neck cancer treated with pencil beam scanning.

    Although predictive power of the Lyman-Kutcher-Burman and Poisson models was limited for this data set, the addition of clinical variables such as age, tumor involvement, hypertension, or sex remarkably increased model performance.

    Based on our assessment, the maximum dose in the optical apparatus is confirmed the most intuitive risk factor. However, above a certain dose threshold, clinical patient characteristics are the deciding factors for the onset of RION. We observed a tendency toward a volume effect that, if confirmed, would imply a benefit for high precision radiation therapy techniques such as proton therapy for the treatment of patients with high clinical risk for RION.
