"We can't change that while they're in the hospital": Unveiling the manifestations of infrastructural violence and wound care for people who inject drugs.

Healthcare avoidance or delays for wounds and related skin- and soft-tissue infections are often attributed to negative interactions with medical providers. An infrastructural violence framework posits that healthcare infrastructure serves as a material channel for structural violence, maintaining inequities in healthcare experiences and outcomes. Infrastructural violence ensues when infrastructure is designed for some members or groups within a society while perpetuating violence among others.

Suture Anchor Fixation of the Pediatric Posteromedial and Posterolateral Menisco-Tibial Ligament Complex Matches or Exceeds Native Tissue Strength: A Cadaveric Study.

Objectives: To compare the biomechanical strength and stiffness of the native posteromedial and posterolateral meniscotibial ligament complex (MTLC) to suture anchor repair of the MTLC.

Methods: Biomechanical testing was performed on 24 fresh-frozen pediatric human knees. Four conditions were tested: native posteromedial MTLC (n=14), native posterolateral MTLC (n=14), posteromedial MTLC repair (n=5), and posterolateral MTLC repair (n=5).

Differential effects of statins on the anti-dyskinetic activity of sub-anesthetic ketamine.

Sub-anesthetic ketamine has been demonstrated to reduce abnormal involuntary movements (AIMs) in preclinical models of L-DOPA-induced dyskinesia (LID) and retrospective Parkinson's disease (PD) case reports. In this study, we examined the effects on LID of two different statins alone and in combination with ketamine in unilateral 6-hydroxydopamine-lesioned male rats, the standard model for preclinical LID studies. Ketamine attenuated the development of AIMs, while the non-polar lovastatin only showed anti-dyskinetic activity early in the priming period but did not prevent the development of LID, and the polar pravastatin showed no anti-dyskinetic activity.

Systematic Review of Randomized Controlled Trials Evaluating the Use of Platelet-Rich Plasma for Knee Osteoarthritis: Adherence to Minimum Information for Studies Evaluating Biologics in Orthopaedics.

Background: The Minimum Information for Studies Evaluating Biologics in Orthopedics (MIBO) guidelines were developed in May 2017 to encourage improved reporting standards, promote increased transparency and reproducibility, and enhance clinical evaluation capabilities. The MIBO guidelines consist of 23 checklist items considered necessary to critically appraise clinical studies evaluating platelet-rich plasma (PRP).

Purpose: To assess randomized controlled trials that evaluated PRP for the treatment of knee osteoarthritis in order to systematically review their adherence to the MIBO guidelines.

Mental Health Treatment among U.S. Military Veterans: Insights from the National Health Interview Survey.

Background: In the United States (U.S.), the prevalence of anxiety and depression is increasing, yet significant barriers to mental health treatment remain.

Patellofemoral Cartilage Injury and Treatment.

Osteochondral and chondral injuries of the patellofemoral joint are common in active patients, and effective management requires a thorough physical and imaging evaluation, a detailed understanding of the unique anatomic and biomechanical joint properties contributing to these injuries, and an appropriate selection of treatment modality. Diagnosis of patellofemoral chondral injuries can be challenging, and differentiating between various causes of anterior knee pain is crucial to successful outcomes. Once identified, nonsurgical treatments including physical therapy, bracing, and injections are a mainstay of initial management.

T Clusters Are More Sensitive Than Mean T Change to Detect Early and Longitudinal Changes in Anterior Cruciate Ligament Reconstructed and Healthy Knees.

Background: Post-traumatic osteoarthritis (PTOA) often follows anterior cruciate ligament reconstruction (ACLR), leading to early cartilage degradation. Change in mean T fails to capture subject-specific spatial-temporal variations, highlighting the need for robust quantitative methods for early PTOA detection and monitoring.

Purpose/hypothesis: Develop and apply 3D T cluster analysis to ACLR and healthy knees over 2.

Cardiovascular hemodynamic response to peak exercise in individuals with multiple sclerosis.

Multiple sclerosis (MS) is a chronic neurological condition resulting in decreased aerobic capacity (peak VO). The hemodynamic responses to peak exercise in MS are unknown. Further, it is unknown if the hemodynamic responses are due to disease or fitness.

Open label pilot of personalized, neuroimaging-guided theta burst stimulation in early-stage Alzheimer's disease.

Background: Alzheimer's disease (AD) is characterized by cerebral amyloid plaques and neurofibrillary tangles and disruption of large-scale brain networks (LSBNs). Transcranial magnetic stimulation (TMS) has emerged as a potential non-invasive AD treatment that may serve as an adjunct therapy with FDA approved medications.

Methods: We conducted a 10-subject open label, single site study evaluating the effect of functional connectivity-resting state functional MRI guided-approach to TMS targeting with dysfunctional LSBNs in subjects with biomarker-confirmed early-stage AD (https://clinicaltrials.

Effect of Anatomic Variations in the Anterior Tibial Artery on Risk of Injury During Orthopaedic Knee Surgeries.

Background: Injury to the posterior vasculature is a potential complication in orthopaedic knee surgery that may be associated with variations in its anatomy, such as the type II-A2 variant, which places the anterior tibial artery (ATA) in closer proximity to the tibia. However, how close surgical instrumentation comes to injuring the ATA is not well described.

Purpose: To determine how the type II-A2 variant of the popliteal vasculature affects proximity of the ATA to instrumentation for orthopaedic knee procedures.

E-cigarette (EC) and heated tobacco product (HTP) use in the United Arab Emirates, an emerging EC and HTP market: A cross-sectional analysis of the International Tobacco Control (ITC) UAE Survey.

Introduction: E-cigarettes (ECs) and heated tobacco products (HTPs) are recent arrivals to the nicotine product market in the Middle East, which are rapidly growing in popularity in the region. There is a lack of surveillance data at the country-level on use of these products and factors associated with their use.

Methods: This study analyzed a subset of data from the UAE Healthy Future Study, a population-based cohort study of the Emirati population, to determine the factors associated with EC and HTP use among a sample of Emirati adults (≥ 18 years).

Multiple material need insecurities and severity of psychological distress during the COVID-19 pandemic among women who use drugs.

Background: The COVID-19 pandemic highlighted the salience of material needs and financial precarity on mental health and distress. Women who use drugs (WWUD) experienced significant mental distress and multiple material need insecurities before the pandemic. However, research is limited on the nature of these insecurities during the pandemic despite both material scarcity and mental distress placing WWUD at greater risk of drug-related harms such as overdose.

Intrinsically Slow Cooling of Hot Electrons in CdSe Nanocrystals Compared to CdS.

The utilization of excited charge carriers in semiconductor nanocrystals (NCs) for optoelectronic technologies has been a long-standing goal in the field of nanoscience. Experimental efforts to extend the lifetime of excited carriers have therefore been a principal focus. To understand the limits of these lifetimes, in this work, we theoretically study the time scales of pure electron relaxation in negatively charged NCs composed of two prototypical materials: CdSe and CdS.

Harm Reduction: The Neglected Pillar of US Drug Policy.

Harm reduction programs provide tools that enable people who use drugs to do so more safely in a nonstigmatizing environment without the goal of them necessarily seeking treatment or abstinence. Most harm reduction programs in the United States distribute sterile syringes and naloxone and safely dispose of used syringes and other drug use supplies. Many also provide drug checking services, and other safer use supplies.

"It always needs a higher level of care than what I can provide": Practical, ethical, and administrative tensions arising from the integration of wound care services into syringe service programs in Maryland.

Introduction: The emergence of xylazine into the U.S. drug supply has increased demand for wound care services among people who inject drugs (PWID).

Definitive Radiotherapy for Oligometastatic and Oligoprogressive Thyroid Cancer: A Potential Strategy for Systemic Therapy Deferral.

Background: Definitive radiotherapy (dRT) has been shown to be an effective option for patients with oligometastatic and oligoprogressive cancers; however, this approach has not been well-studied in metastatic thyroid cancer.

Methods: This retrospective cohort included 119 patients with oligometastatic (34%) and oligoprogressive (66%) metastatic thyroid cancer treated from 2005 to 2024 with 207 dRT courses for 344 sites (50% thoracic, 37% bone, 7.5% brain, 4% abdominopelvic, and 1.

Differential effects of statins on the anti-dyskinetic activity of sub-anesthetic ketamine.

Sub-anesthetic ketamine has been demonstrated to reduce abnormal involuntary movements (AIMs) in preclinical models of L-DOPA-induced dyskinesia (LID) and retrospective Parkinson's disease case reports. In this study, we examined the effects on L-DOPA-induced dyskinesia of two statins alone and in combination with ketamine in unilateral 6-hydroxydopamine-lesioned male rats, the standard preclinical LID model. Sub-anesthetic ketamine attenuated the development of AIMs, while lovastatin only showed anti-dyskinetic activity at the beginning of the priming but did not prevent the development of LID.

Increasing incidence of concussion and head injury due to electric biking: a 10-year sex- and age-specific analysis of national injury data.

Objectives: Electric biking (e-biking) is a rapidly growing recreation, sport, and mode of transportation that often presents to emergency departments (EDs) with high-impact head injuries. This study aimed to evaluate the epidemiology of e-bike-related concussions and closed-head injuries (CHI) to inform more effective injury prevention strategies.

Methods: The National Electronic Injury Surveillance (NEISS) was queried for e-bike related concussions and CHIs presented to national EDs from 1 January 2013-31 December 2022.

Wound-associated agents in the unregulated drug supply: Evidence from a statewide drug checking program.

Background: While the unregulated drug market has seen dramatic increases in fentanyl adulteration in the past decade, other adulterants have impacted the recent volatility of the drug supply. There has been recent documentation related to the presence of wound-associated substances; however, there is a lack of data showing the prevalence of these substances across unregulated drug market samples over time. The aim of this paper is to examine known and potential wound-associated agents' (xylazine, levamisole, medetomidine) prevalence in Maryland's unregulated drug supply.

Efficacy and Safety of Selective RET Inhibitors in Patients with Advanced Hereditary Medullary Thyroid Carcinoma.

Two selective RET inhibitors (RETis) are effective in treating ()-altered medullary thyroid carcinoma (MTC), but clinical trials did not distinguish responses between hereditary MTC (hMTC) and sporadic MTC (sMTC) cases. We reviewed our single-center experience using a RETi to treat advanced hMTC. We conducted a retrospective cohort study of patients with hMTC treated with a selective RETi at a tertiary cancer center.

Blunted Exercise Pressor Response to Isometric Knee Extension and Post Exercise Ischemia in Individuals with Down Syndrome.

Introduction: Individuals with Down syndrome (DS) exhibit autonomic dysfunction, which contributes to reduced work capacity. The metaboreflex produces exercise-induced sympathoexcitation and can be assessed via post-exercise muscle ischemia (PEMI). Blunted sympathoexcitation is common in individuals with DS and contributes to the physiological basis for reduced work capacity observed this population, but the influence of the metaboreflex is unknown.

Polygenic Score for Clinicopathologic Features and Survival Outcomes in Papillary Thyroid Carcinoma.

Importance: Genome-wide association studies have identified germline variants associated with the development of papillary thyroid carcinoma (PTC) that can be used to construct a polygenic score (PGS). It is important to determine whether patients with higher germline genetic risk, as summarized using PGS, present with more aggressive disease and/or develop worse clinical outcomes.

Objective: To assess whether germline risk defined by PGS is associated with clinicopathologic features and survival outcomes for patients with PTC.
