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.

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.

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.

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.

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.

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 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.

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.

Article Synopsis
  • Around 5-10% of pancreatic cancer patients don't express CA 19-9, and it's unclear how this affects their cancer severity and prognosis.
  • A study analyzed data from 88,749 pancreatic cancer patients, finding that non-expressors had a higher chance of distant metastasis and a shorter median overall survival compared to those with normal CA 19-9 levels.
  • The findings suggest that patients who are non-expressors of CA 19-9 might need different diagnostic approaches and more aggressive treatment strategies.
