Quantitative assessment of the vascularity of the skeletally immature patella: a cadaveric study using MRI.

Purpose: While predominant blood supply to the adult patella enters inferomedially, little is known about skeletally immature patellar perfusion. Improved knowledge of immature patella vascularity can further understanding of osteochondritis dissecans, dorsal defects of the patella and bipartite patella, and help ensure safe surgical approaches. We hypothesized that the immature patella would exhibit more uniform blood flow.

Percutaneous and Open Tracheostomy in Patients With COVID-19: The Weill Cornell Experience in New York City.

Objective: Report long-term tracheostomy outcomes in patients with COVID-19.

Study Design: Review of prospectively collected data.

Methods: Prospectively collected data were extracted for adults with COVID-19 undergoing percutaneous or open tracheostomy between April 4, 2020 and June 2, 2020 at a major medical center in New York City.

A cost analysis of two- versus three-instrument robotic-assisted inguinal hernia repair with mesh: time is money.

Equipment expenses and operating times can lead to higher costs with robotic surgery. We compared the cost-effectiveness of 2- vs. 3-instrument (2i vs.

Balloon occlusion as an adjunctive technique during sclerotherapy of Puig's classified advanced venous malformations.

Objective: Puig types 2 through 4 venous malformations (VMs) are challenging to treat with sclerotherapy given their robust systemic outflow. Endovenous balloon occlusion offers a means of temporarily occluding systemic venous outflow to allow for more complete sclerotherapy. This study reviews our experience of implementing this technique in patients with Puig advanced (types 2 through 4) VMs.

Effect of Antimicrobial Therapy on Respiratory Hospitalization or Death in Adults With Idiopathic Pulmonary Fibrosis: The CleanUP-IPF Randomized Clinical Trial.

Importance: Alteration in lung microbes is associated with disease progression in idiopathic pulmonary fibrosis.

Objective: To assess the effect of antimicrobial therapy on clinical outcomes.

Design, Setting, And Participants: Pragmatic, randomized, unblinded clinical trial conducted across 35 US sites.

Laparoscopic management of a primary posterior cul-de-sac abdominal ectopic pregnancy.

Objective: To report a case of laparoscopic management of a primary posterior cul-de-sac abdominal ectopic pregnancy (AEP).

Design: Video article.

Setting: Academic medical center.

Early introductions and transmission of SARS-CoV-2 variant B.1.1.7 in the United States.

The emergence and spread of SARS-CoV-2 lineage B.1.1.

Deep sequencing of DNA from urine of kidney allograft recipients to estimate donor/recipient-specific DNA fractions.

Kidney transplantation is the treatment of choice for patients with end-stage kidney failure, but transplanted allograft could be affected by viral and bacterial infections and by immune rejection. The standard test for the diagnosis of acute pathologies in kidney transplants is kidney biopsy. However, noninvasive tests would be desirable.

Public perception on opioids & pain management after major surgery.

Background: In the US, opioids are overprescribed after surgery contributing to the opioid epidemic. Patients' expectations regarding postoperative opioids remains unclear.

Methods: A representative survey using random-digit dial telephone sampling of English-speaking adults in US was conducted from August 28 to December 11, 2019.

Treatment of knee osteoarthritic pain with platelet-rich plasma: a systematic review of clinical studies.

Knee osteoarthritis is a degenerative joint disease that is secondary to degradation of articular cartilage, reformation of subchondral bone through degradation and proliferation as well as presence of synovitis. This systematic review was conducted and reported as per Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A total of 30 of the 48 comparators showed statistically significant superiority with platelet-rich plasma (PRP) compared with a control, while the other 16 comparators showed no significant difference between PRP and the comparator.

Exclusion of SARS-COV-2 From Two Maine Overnight Camps July-August 2020.

Objectives: Summer camp can positively affect self-esteem and social skills. Most United States summer camps did not open during 2020 because of concerns about severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). Our objective is to describe exclusion strategies successfully used by 2 summer camps in Maine.

Post-operative complications following masculinizing genitoplasty in moderate to severe genital atypia: results from a multicenter, observational prospective cohort study.

Introduction: Differences of sex development (DSD) are congenital conditions in which there is atypical chromosomal, gonadal and/or phenotypic sex. A phenotype of severe genital atypia in patients raised as male is a relatively rare occurrence and standards for management are lacking. Decision making for early surgical planning in these rare cases includes, but is not limited to, degree of atypia, location of testes, and presence of Mϋllerian remnants.

Bleeding in Critically Ill Children-Review of Literature, Knowledge Gaps, and Suggestions for Future Investigation.

Clinically significant bleeding complicates up to 20% of admissions to the intensive care unit in adults and is associated with severe physiologic derangements, requirement for significant interventions and worse outcome. There is a paucity of published data on bleeding in critically ill children. In this manuscript, we will provide an overview of the epidemiology and characteristics of bleeding in critically ill children, address the association between bleeding and clinical outcomes, describe the current definitions of bleeding and their respective limitations, and finally provide an overview of current knowledge gaps and suggested areas for future research.

Association Between Caregiver Strain and Self-Care Among Caregivers With Diabetes.

Importance: Caregiver strain has been shown to be associated with adverse effects on caregivers' health, particularly among those with cardiovascular disease. Less is known about the association of caregiver strain with health behaviors among caregivers with diabetes, a disease that requires a high degree of self-care.

Objective: To examine the association between caregiver strain and diabetes self-care among caregivers with diabetes.

Age-Dependent Heterogeneity in the Efficacy of Prophylaxis With Enoxaparin Against Catheter-Associated Thrombosis in Critically Ill Children: A Post Hoc Analysis of a Bayesian Phase 2b Randomized Clinical Trial.

Objectives: We explored the age-dependent heterogeneity in the efficacy of prophylaxis with enoxaparin against central venous catheter-associated deep venous thrombosis in critically ill children.

Design: Post hoc analysis of a Bayesian phase 2b randomized clinical trial.

Setting: Seven PICUs.

Kidney recipients with allograft failure, transition of kidney care (KRAFT): A survey of contemporary practices of transplant providers.

Kidney allograft failure and return to dialysis carry a high risk of morbidity. A practice survey was developed by the AST Kidney Pancreas Community of Practice workgroup and distributed electronically to the AST members. There were 104 respondents who represented 92 kidney transplant centers.
