The purpose of the current study is to compare the outcomes of open subpectoral biceps tenodesis (BT) to arthroscopic repair (AR) for SLAP tears in patients under the age of 30 years.

A retrospective review of patients under the age of 30 years who underwent either isolated BT or AR for a diagnosis of a SLAP tear between 2011 and 2019 was performed. Patients were included if they were >16 years old at the time of surgery, had an isolated SLAP tear involving instability of the biceps-labral anchor (types II-IV), were skeletally mature, and had a minimum follow-up of 12 months. The American Shoulder & Elbow Surgeons score, visual analog scale, Subjective Shoulder Value, patient satisfaction, willingness to undergo surgery again, revisions, and return to play (RTP) were evaluated. A P value of <.05 was considered statistically significant.

Our study included 103 patients in total; 29 patients were treated with BT, and 74 were treated with AR. The mean age was 24.8 years, and the mean follow-up duration was 60 months. P505-15 At final follow-up, there was no difference between treatment groups in any of the functional outcome measures assessed (P>.05). Overall, there was no significant difference in the total rate of RTP (BT 76.3%, AR 85%; P= .53), timing of RTP (BT 8.8 months, AR 9.4 months; P= .61), and total rate of RTP among overhead athletes (BT 84.2%, AR 83.3%; P>.99). Among those undergoing AR, 9 required a revision procedure (11.5%) compared to none treated with BT (P=.11).

In patients under the age of 30 years with a symptomatic isolated SLAP tear, BT may be a reliable alternative to AR.

To examine acute postoperative opioid consumption in patients undergoing hip arthroscopy and randomized to either receive a preoperative lateral quadratus lumborum block or sham injection.

This trial randomized 46 subjects undergoing hip arthroscopy with a single surgeon to receive a preoperative lateral quadratus lumborum block (40 mL, ropivacaine 0.25%) or sham injection. The primary outcome was postoperative opioid consumption in patients with and without a block. All opioid medications were converted to morphine milligram equivalents for comparisons. Categorical data were compared with χ
tests and Fisher exact tests where appropriate. Continuous data were compared with 2-sided t-test and Wilcoxon rank-sum tests.

Forty-six subjects scheduled for elective hip arthroscopy were successfully consented and randomized. Demographic and clinical characteristics did not differ. Postoperative opioid consumption decreased 28.3% in patients who received a preoperative lateral quadratus lumborum block (P= .04). Level I, randomized controlled trial.

Approximately 73% of children with severe neurological impairment (SNI) can experience episodes of pain and irritability often of unknown origin (PIUO). Limited research exists on how these experiences of PIUO may affect parental caregivers and families. The primary objective of this study was to understand the parental caregiver experience of caring for a child with SNI who experiences persistent PIUO.

We conducted a qualitative study using semi-structured interviews to explore the experience of parental caregivers of children with SNI. Interview guide questions focused on exploring pain behaviours, the diagnostic process, pharmacological and non-pharmacological management, healthcare-team support, discussion surrounding irritability, and family impact. Interviews were conducted until thematic saturation was reached. Interviews were audio-recorded, transcribed verbatim, and coded and analyzed by 2 independent reviewers using thematic analysis.

15 parental caregivers were interviewed, with 93% being motd supportive resources for education and coping for parents.
Patients with advanced cancer often involve family caregivers in health-related decision-making from diagnosis to end-of-life; however, few interventions have been developed to enhance caregiver decision support skills.

Assess the feasibility, acceptability, and potential efficacy of individual intervention components of CASCADE (CAre Supporters Coached to be Adept DEcision Partners), an early telehealth, palliative care coach-led decision support training intervention for caregivers.

Pilot factorial trial using the multiphase optimization strategy (October 2019-October 2020). Family caregivers and their care recipients with newly-diagnosed advanced cancer (n=46 dyads) were randomized to1 of 8 experimental conditions that included a combination of one of the following three CASCADE components 1) effective decision support psychoeducation; 2) decision support communication training; and 3) Ottawa Decision Guide training. Feasibility was assessed by completion of sessions and questionnaires (predefined aswith advanced cancer. CASCADE components were acceptable and the trial design feasible, providing promising future directions for palliative care intervention development and testing. Pilot results will inform a fully-powered trial.

It is important to address fatigue and co-occurring symptoms during chemotherapy to preserve quality of life in patients with gastrointestinal (GI) cancer.

To conduct a randomized controlled pilot study of a Yoga Skills Training (YST) intervention compared to an attention control (AC) among adults diagnosed with GI cancer.

YST consisted of four 30-minute sessions delivered individually during chemotherapy plus home practice. AC provided empathic attention plus home diaries. Patient-reported (PROMIS T-score) assessments of fatigue, depressive symptoms, sleep disturbances, and psychological stress (Perceived Stress Scale) were collected at chemotherapy visits baseline, Week 8, Week 10 and Week 14, and analyzed using a mixed effects model. Inflammatory cytokines were assessed at baseline and Week 10.

Forty-four of 77 adults approached agreed to participate (57%; YST n=23; AC n=21). Participants' mean age was 58 years and 48% were men. Participants randomized to YST reported a larger decline in fatigue (-2.4 difference, d=0.30) and depressive symptoms (-2.5 difference, d=0.30) than AC participants from baseline to Week 10 and sleep disturbances at Week 8 (-3.9 difference, d=0.50). Differences in magnitude of change in symptoms were consistent with or exceeded a minimally important difference. Psychological stress decreased more in the AC at Week 10 (d=0.30). Reductions in inflammatory cytokines (IL-6, sTNF R1) were larger in the YST group than AC.

YST showed promise for improving fatigue, depressive symptoms, sleep disturbances, and inflammation. YST is also feasible and reaches patients underrepresented in yoga research (i.e., GI cancer, men), thus warranting further examination.

However, the mechanism by which a prenatal, short-lived increase of cytokines results in adverse neurodevelopmental outcomes remains largely unknown. Microglia-the brain's resident immune-cells-stand as fundamental cellular mediators, being highly sensitive and responsive to immune signals, which also play key roles during normal development. The fractalkine signaling axis is a neuron-microglia communication mechanism used to regulate neurogenesis and network formation. Previously, we showed hippocampal reduction of fractalkine receptor (Cx3cr1) mRNA at postnatal day (P) 15 in male offspring exposed to maternal immune activation induced with lipopolysaccharide (LPS) during late gestation, which was concomitant to an increased dendritic spine density in the dentate gyrus, a neurogenic niche. The current study sought to evaluate the origin and impact of this redfractalkine signaling has been recently associated with an increased risk for neurodevelopmental disorders. We show that an acute immune insult during late gestation can alter fractalkine signaling by reducing the microglial CX3CR1 protein expression, highlighting neuron-microglial fractalkine signaling as a relevant target underlying the outcomes of environmental risk factors on neurodevelopmental disorders.While the immune system is essential for survival, an excessive or prolonged inflammatory response, such as that resulting from sustained heavy alcohol use, can damage the host and contribute to psychiatric disorders. A growing body of literature indicates that the immune system plays a critical role in the development and maintenance of alcohol use disorder (AUD). As such, there is enthusiasm for treatments that can restore healthy levels of inflammation as a mechanism to reduce drinking and promote recovery. In this qualitative literature review, we provide a conceptual rationale for immune therapies and discuss progress in medications development for AUD focused on the immune system as a treatment target. This review is organized into sections based on primary signaling pathways targeted by the candidate therapies, namely (a) toll-like receptors, (b) phosphodiesterase inhibitors, (c) peroxisome proliferator-activated receptors, (d) microglia and astrocytes, (e) other immune pharmacotherapies, and (f) behavioral therapies. As relevant within each section, we examine the basic biological mechanisms of each class of therapy and evaluate preclinical research testing the role of the therapy on mitigating alcohol-related behaviors in animal models. To the extent available, translational findings are reviewed with discussion of completed and ongoing randomized clinical trials and their findings to date. An applied and clinically focused approach is taken to identify the potential clinical applications of the various treatments reviewed. We conclude by delineating the most promising candidate treatments and discussing future directions by considering opportunities for immune treatment development and personalized medicine for AUD.Alzheimer's disease (AD) pathology is characterized by amyloid-β (Aβ) deposition and tau hyper-phosphorylation, accompanied by a progressive cognitive decline. Monocytes have been recently shown to play a major role in modulating Aβ pathology, and thereby have been pointed as potential therapeutic targets. However, the main challenge remains in identifying clinically relevant interventions that could modulate monocyte immune functions in absence of undesired off-target effects. Erythropoietin (EPO), a key regulator of erythrocyte production, has been shown to possess immunomodulatory potential and to provide beneficial effects in preclinical models of AD. However, the transition to use recombinant human EPO in clinical trials was hindered by unwanted erythropoietic effects that could lead to thrombosis. Here, we used a recently identified non-erythropoietic analogue of EPO, ARA 290, to evaluate its therapeutic potential in AD therapy. We first evaluated the effects of early systemic ARA 290 administration on AD-like pathology in an early-onset model, represented by young APP/PS1 mice.
