Pharmacokinetics, Efficacy, and Safety of a SARS-CoV-2 Antibody Treatment in Pediatric Participants: An Open-Label Addendum of a Placebo-Controlled, Randomized Phase 2/3 Trial.

Introduction: Bamlanivimab and etesevimab (BAM + ETE) are monoclonal antibodies (mAbs) effective in reducing COVID-19-related hospitalizations and all-cause mortality in adult participants at increased risk for severe disease. We present pharmacokinetic (PK), efficacy, and safety results from pediatric participants (< 18 years of age) with COVID-19 who were treated with BAM + ETE.

Methods: In an addendum to the phase 2/3 BLAZE-1 clinical trial (NCT04427501), pediatric participants received open-label weight-based dosing (WBD, n = 94) based on exposure-matching to the authorized dose of BAM + ETE in adult participants.

Molecular Profiling of Syringocystadenocarcinoma Papilliferum Reveals RAS-Activating Mutations.

Context.—: Syringocystadenocarcinoma papilliferum (SCACP) is a rare adnexal carcinoma and the malignant counterpart of syringocystadenoma papilliferum (SCAP), which is commonly located on the head and neck and may arise in association with a nevus sebaceus. RAS mutations have been identified in both SCAP and nevus sebaceus.

General Anesthetics in CAncer REsection Surgery (GA-CARES) randomized multicenter trial of propofol vs volatile inhalational anesthesia: protocol description.

Background: Studies indicate that patients can be "seeded" with their own cancer cells during oncologic surgery and that the immune response to these circulating cancer cells might influence the risk of cancer recurrence. Preliminary data from animal studies and some retrospective analyses suggest that anesthetic technique might affect the immune response during surgery and hence the risk of cancer recurrence. In 2015, experts called for prospective scientific inquiry into whether anesthetic technique used in cancer resection surgeries affects cancer-related outcomes such as recurrence and mortality.

Localised chronic fibrosing vasculitis versus erythema elevatum diutinum.

A woman in her 70s was referred for a painless plaque on the shin, present for 2 years and progressing in thickness. Examination revealed a large erythematous to violaceous indurated plaque with cobblestone appearance. Biopsy revealed an inflammatory infiltrate of neutrophils with scattered histiocytes, lymphocytes, eosinophils and plasma cells interspersed with areas of lamellar fibrosis and focal areas of vascular damage, suggestive of a localised chronic fibrosing vasculitis of the skin.

Cost of Intralesional Collagenase Clostridium Histiolyticum Therapy Versus Surgery for the Management of Peyronie's Disease: A Claims-Based Analysis (2009-2019).

Background: Collagenase Clostridium histolyticum (CCH), which was approved by the FDA for the treatment of Peyronie's disease (PD) in 2013, may obviate the need for surgery but its historically high cost must be considered when offering CCH vs surgical intervention to affected patients.

Aim: To compare trends of intralesional injections vs surgical treatment for PD and assess the contemporary cost of treatment with CCH vs surgical intervention.

Methods: We reviewed 2009-2019 MarketScan Commercial Claims data to identify all men 18 years and older with PD.

Management of diffuse alveolar hemorrhage in the hematopoietic stem cell transplantation population: A systematic review.

Pulmonary complications post-hematopoietic stem cell transplantation (HSCT) such as diffuse alveolar hemorrhage (DAH) can occur in 2% to 14% of HSCT patients and have a mortality greater than 80%. Diffuse alveolar hemorrhage is considered to be an inflammatory response; therefore, HSCT patients are primarily treated with different types of systemic corticosteroids with varying dosages. Other treatments currently reported in the literature in conjunction with corticosteroids include aminocaproic acid, recombinant factor VIIa (rFVIIa), and etanercept.

Disparities in magnetic resonance imaging of the prostate for traditionally underserved patients with prostate cancer.

Background: Prebiopsy magnetic resonance imaging (MRI) of the prostate improves detection of significant tumors, while decreasing detection of less-aggressive tumors. Therefore, its use has been increasing over time. In this study, the use of prebiopsy MRI among Medicare beneficiaries with prostate cancer was examined.

Confirmed Hypoglycemia Without Whipple Triad: A Rare Case of Hyper-Warburgism.

Spontaneous hypoglycemia in nondiabetic patients poses a diagnostic challenge. Hypoglycemia in malignancy has several etiologies; an extremely rare mechanism is the Warburg effect causing excess lactate production and avid glucose consumption. We describe the clinical course of a 52-year-old man admitted for chest wall mass and severe but asymptomatic hypoglycemia.

Influence of excess weight on lower-extremity vertical stiffness and metabolic cost of walking.

The purpose was to test whether lower-extremity vertical stiffness and gait mechanics explain differences in energy cost of walking (Cw) between individuals with normal weight (NW) and obesity (OB). Ten OB (33.1 ± 2.

Hot isostatic pressing (HIP) to achieve isotropic microstructure and retain as-built strength in an additive manufacturing titanium alloy (Ti-6Al-4V).

Hot isostatic pressing (HIP) treatments are traditionally used to seal internal porosity, because defects exist in as-built Ti-6Al-4V parts produced by electron-beam melting powder-bed fusion. Standard HIP treatment of Ti-6Al-4V parts results in decreased strength due to coarsening of the microstructure. We present a new HIP strategy with the following steps: hold above the β-transus, rapid quenching, and tempering.

Creating a Pathway for Multidisciplinary Shared Decision-Making to Improve Communication During Preoperative Assessment.

Shared decision-making (SDM) is essential for high-quality surgical care. Barriers to SDM exist in clinical practice but there is evidence these obstacles can be overcome. SDM requires clinician and patient engagement.

A novel anesthesiologist-led multidisciplinary model for evaluating high-risk surgical patients at a comprehensive cancer center.

The objective of this retrospective analysis was to describe the development and implementation of an anesthesiologist-led multidisciplinary committee to evaluate high-risk surgical patients in order to improve surgical appropriateness. The study was conducted in an anesthesia preoperative evaluation clinic at an academic comprehensive cancer center. One hundred sixty-seven high-risk surgical patients with cancer-related diagnoses were evaluated and discussed at a High-Risk Committee (HRC) meeting to determine surgical appropriateness and optimize perioperative care.

Factors associated with an increased risk of perioperative cardiac arrest in emergent and elective craniotomy and spine surgery.

Objective: Cardiac arrest following neurosurgery is a devastating complication associated with significant postoperative morbidity and mortality. There are no published studies that have used a large and robust multicenter database to specifically examine demographic and surgical risk factors associated with cardiac arrests following craniotomy and spine surgeries, respectively.

Patients And Methods: We retrospectively analyzed data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database for the period between January 1, 2007 and December 31, 2013, focusing on cardiac arrest associated with craniotomy and spine surgery from the intraoperative period to 30days after surgery.

Analysis of Variability in Intraoperative Fluid Administration for Colorectal Surgery: An Argument for Goal-Directed Fluid Therapy.

Background: Fluid therapy in the perioperative period varies greatly between anesthesia providers and may have a negative impact on surgical outcomes.

Methods: We conducted a retrospective analysis of 705 elective colorectal cases consisting of colectomies, ileocolic resections, and low anterior resections at an academic institution from January 1, 2010 to May 29, 2015, collected by our electronic medical record before implementation of Enhanced Recovery After Surgery (ERAS) pathways.

Results: The mean for total crystalloid administration was 2578 mL with a standard deviation (SD) that was approximately 50% of the mean value.

Identifying Patient Characteristics Associated With Deficits in Surgical Decision Making.

Background: Patient involvement in surgical decisions is formalized in the informed consent process, which should reflect that the patient understands their diagnosis, planned procedure, and the associated risks and benefits before consenting to treatment. If high-quality shared decision making has occurred, the treatment chosen should best match the goals and preferences of the patient. Little information currently exists that analyzes factors associated with decisional quality in surgery.

Nondestructive evaluation of a new hydrolytically degradable and photo-clickable PEG hydrogel for cartilage tissue engineering.

Unlabelled: Photopolymerizable and hydrolytically labile poly(ethylene glycol) (PEG) hydrogels formed from photo-clickable reactions were investigated as cell delivery platforms for cartilage tissue engineering (TE). PEG hydrogels were formed from thiol-norbornene PEG macromers whereby the crosslinks contained caprolactone segments with hydrolytically labile ester linkages. Juvenile bovine chondrocytes encapsulated in the hydrogels were cultured for up to four weeks and assessed biochemically and histologically, using standard destructive assays, and for mechanical and ultrasound properties, as nondestructive assays.

Analysis of Unplanned Postoperative Admissions to the Intensive Care Unit.

Purpose: To investigate factors associated with unplanned postoperative admissions to the intensive care unit (ICU).

Methods: Data from the National Anesthesia Clinical Outcomes Registry (NACOR) were analyzed. We performed univariate and multivariate logistic regression to identify patient- and surgery-specific characteristics associated with unplanned postoperative ICU admission.

UVEAL MELANOMA EXTENSION TO THE OPTIC CHIASM.

Purpose: Case report describing a patient who developed intracranial extension of a uveal melanoma through the optic nerve.

Methods: We reviewed the patient's medical history and images. A 41-year-old woman who was blind in one eye had a uveal melanoma that extended through the optic nerve into the optic chiasm and involved the hypophysis.
