Combination product of dermal matrix, preconditioned human mesenchymal stem cells and timolol promotes wound healing in the porcine wound model.

A combination product of human mesenchymal stem/stromal cells (MSCs) embedded in an extracellular matrix scaffold and preconditioned with hypoxia and the beta-adrenergic receptor antagonist, timolol, combined with sustained timolol application post implantation, has shown promising results for improving wound healing in a diabetic mouse model. In the present study, we extend those findings to the more translatable large animal porcine wound model and show that the combined treatment promotes wound reepithelialization in these excisional wounds by 40.2% and increases the CD31 immunostaining marker of angiogenesis compared with the matrix control, while maintaining an accumulated timolol plasma concentration below the clinically safe level of 0.

Postoperative Radiation Therapy in Oral Cavity Verrucous Carcinoma.

Objectives/hypothesis: We investigate the clinicopathologic and treatment factors associated with the use of postoperative radiation therapy (PORT) and its effect on overall survival (OS) for patients with oral cavity verrucous carcinoma (VC).

Study Design: Retrospective cohort study.

Methods: A retrospective cohort study of the National Cancer Database (NCDB) from 2006 to 2015 was performed.

Severe altered mentation due to cervicothoracic intrathecal pump after correction of cervical stenosis: a case report.

Background: Cerebral spinal fluid (CSF) dynamics are complex and changes in spinal anatomy may influence the rostrocaudal movement of intrathecal medications. We present the first reported case demonstrating that acute cervical spinal stenosis may impede the distribution of adjacent intrathecal medications, and that correction of such stenosis and the resulting changes in CSF flow may necessitate significant adjustments in the intrathecal infusates.

Case Presentation: We present a case of a 60-year-old male patient with a cervicothoracic intrathecal pump (ITP) infusing morphine, bupivacaine, and baclofen for chronic neck pain.

Transcarotid artery revascularization (TCAR): a technical video.

Carotid revascularization is an important method of stroke prevention and includes carotid endarterectomy and transfemoral carotid angioplasty and stenting. More recently, a hybrid open-endovascular approach, termed transcarotid artery revascularization (TCAR), is garnering increased attention. Although fundamentally a 'stenting procedure', unlike transfemoral carotid angioplasty and stenting, TCAR allows for a proximal neuroprotection strategy based on flow reversal.

Phase 2a randomized clinical trial of dupilumab (anti-IL-4Rα) for alopecia areata patients.

Background: Treatments for alopecia areata (AA) patients with extensive scalp hair loss are limited, and recent evidence supports a role for type 2 T-cell (Th2)-immune response in AA. Dupilumab, a monoclonal antibody inhibiting Th2 signaling, approved for type 2 diseases including atopic dermatitis, was evaluated in AA patients.

Methods: Alopecia areata patients with and without concomitant atopic dermatitis were randomized 2:1 to receive weekly subcutaneous dupilumab (300 mg) or placebo for 24 weeks, followed by another 24-week dupilumab open-label phase.

A Combined Prospective and Retrospective Comparison of Long-Term Functional Outcomes Suggests Delayed Loss of Ambulation and Pulmonary Decline with Long-Term Eteplirsen Treatment.

Background: Studies 4658-201/202 (201/202) evaluated treatment effects of eteplirsen over 4 years in patients with Duchenne muscular dystrophy and confirmed exon-51 amenable genetic mutations. Chart review Study 4658-405 (405) further followed these patients while receiving eteplirsen during usual clinical care.

Objective: To compare long-term clinical outcomes of eteplirsen-treated patients from Studies 201/202/405 with those of external controls.

Passive Recovery Strategies after Exercise: A Narrative Literature Review of the Current Evidence.

Passive recovery techniques are popular and offer a diverse spectrum of options for athletes and the clinicians providing care for them. These techniques are intended to minimize the negative effects of training or competition, thus enabling the athlete a quicker return to peak performance. Current evidence demonstrates improved athlete recovery with compression garments, cold water immersion, partial body cryotherapy, hyperbaric oxygen, and vibratory therapies.

Augmented Spring Ligament Repair in Pes Planovalgus Reconstruction.

Patients with pes planovalgus deformity often have coexisting spring ligament pathology. A primary repair of the ligament may fail during weightbearing due to chronic degeneration of the ligamentous tissue. Augmentation with a suture tape has been suggested to strengthen the repair.

Open-Label Evaluation of Eteplirsen in Patients with Duchenne Muscular Dystrophy Amenable to Exon 51 Skipping: PROMOVI Trial.

BackgroundEteplirsen received accelerated FDA approval for treatment of Duchenne muscular dystrophy (DMD) with mutations amenable to exon 51 skipping, based on demonstrated dystrophin production.ObjectiveTo report results from PROMOVI, a phase 3, multicenter, open-label study evaluating efficacy and safety of eteplirsen in a larger cohort.MethodsAmbulatory patients aged 7-16 years, with confirmed mutations amenable to exon 51 skipping, received eteplirsen 30 mg/kg/week intravenously for 96 weeks.

A 70-Year-Old Man With Conspicuous Thigh Pain and ST-Segment Elevations.

A 70-year-old man presented to the ED with sudden onset of left thigh pain followed by transient chest discomfort. His history included cerebrovascular disease, hypertension, and cocaine and methamphetamine use. Physical examination revealed an uncomfortable male subject with a temperature of 37 °C, heart rate of 129 beats/min, BP of 130/65 mm Hg, and 98% oxygen saturation on room air.

Potential Benefits of Limited Clinical and Radiographic Follow-up After Surgical Treatment of Ankle Fractures.

Introduction: Ankle fractures are one of the most prevalent musculoskeletal injuries, with a significant number requiring surgical treatment. Postoperative complications requiring additional interventions frequently occur during the early postoperative period. We hypothesize that there is a limited need for routine clinical and radiographic follow-up once the fracture is deemed healed.

Chemical Composition of JUUL Pods Collected From Students in California High Schools.

Purpose: To examine the chemical composition of JUUL pods collected from a convenience sample of 16 high schools in California to identify possible consumer modification or counterfeit use.

Methods: Using Gas Chromatography-Mass Spectrometry, we quantitatively analyzed the nicotine, propylene glycol (PG), and vegetable glycerin (VG) in JUUL pods (n = 26) collected from California high schools and compared results to commercial 3% (n = 15) and 5% (n = 24) JUUL pods purchased online.

Results: Most of the collected JUUL pods (24/26 pods) had a nicotine concentration (43.

Size Criteria Is Not Sufficient in Selecting Patients for Local Excision Versus Radical Excision for Rectal Neuroendocrine Tumors >2 cm: A National Cancer Database Analysis.

Background: Patients with rectal neuroendocrine tumors >2 cm often undergo radical surgery, despite limited data supporting this practice. Five- and 10-year survival rates for these patients have been reported previously as 74.8% and 58.

"Cool Knees" as a Measure of Systemic Vascular Resistance in Cardiac Patients.

Introduction: Clinical assessment of cardiac output (CO) and systemic vascular resistance (SVR) in cardiac patients is often inaccurate. Since the genicular arteries form a watershed zone accessible to physical examination, we hypothesized that "cool knees" would reflect abnormalities in central hemodynamics.

Methods: Nineteen patients with cardiac diagnoses, but without distributive shock, had a measurement of skin temperature over the thigh, knee, and foot in parallel with central hemodynamics derived from invasive monitoring.

Trends in Social Media Topics During COVID-19 Among Women Undergoing Assisted Reproductive Technology Treatments.

Patients undergoing fertility treatments, such as in-vitro fertilization (IVF), face unique challenges both physically and mentally. With the emergence of the COVID-19 global pandemic, IVF patients began to face additional obstacles as hospitals and clinics shut down in compliance with recommendations for limiting exposure risk. In order to assess the impact of COVID-19 on IVF patients, we conducted a qualitative analysis using 563 public Instagram posts collected from three randomly selected days in March 2020.

Factor Structure of the Children's Sleep Habits Questionnaire in Young Children with and Without Autism.

The Children's Sleep Habits Questionnaire (CSHQ) is often used to assess sleep in children with autism spectrum disorder (ASD), but little is known about its factor structure in younger children with ASD. We evaluated alternative factor structures and measurement invariance for CSHQ items in 2- to 4-year-olds with ASD or typical development (TD). Bifactor models indicated subscales' variance was subsumed by a general factor predominantly reflecting sleep initiation and nighttime awakening items.

Galectin-3 as a Therapeutic Target for NSAID-Induced Intestinal Ulcers.

Unlabelled: Non-steroidal anti-inflammatory drugs (NSAIDs) induce ulcers in the gastrointestinal tract, including the stomach and small intestine. NSAID-induced gastric ulcers can be prevented by taking acid-neutralizing/inhibitory drugs and cytoprotective agents. In contrast, there are no medicines to control NSAID-induced small intestinal ulcers, which are accompanied by a mucosal invasion of bacteria and subsequent activation of immune cells.

Repurposing Clinical Decision Support System Data to Measure Dosing Errors and Clinician-Level Quality of Care.

We aimed to develop and validate an instrument to detect hospital medication prescribing errors using repurposed clinical decision support system data. Despite significant efforts to eliminate medication prescribing errors, these events remain common in hospitals. Data from clinical decision support systems have not been used to identify prescribing errors as an instrument for physician-level performance.
