Racial Differences in Systemic Immune Parameters in Individuals With Lung Cancer.

Introduction: Racial and ethnic disparities in the presentation and outcomes of lung cancer are widely known. To evaluate potential factors contributing to these observations, we measured systemic immune parameters in Black and White patients with lung cancer.

Methods: Patients scheduled to receive cancer immunotherapy were enrolled in a multi-institutional prospective biospecimen collection registry.

The Impact of a Resident, Fellow, or Physician Assistant on Operative Time and Complication Rate in Closed Reduction and Percutaneous Pin Fixation of Pediatric Distal Humerus Supracondylar Fractures.

Objective: We sought to compare operative times and complications for attending surgeons operating alone or with an assistant including an orthopedic resident, fellow, or physician assistant (PA) for closed reduction and percutaneous pinning (CRPP) of pediatric supracondylar humerus fractures (SCH), an archetypal procedure integral to the education of orthopedic trainees.

Design: Using a retrospective database collected following institutional review board approval, a 1-way ANOVA (non-parametric) was used to assess the effect of assistant absence or presence by type of assistant on mean operative time. We analyzed the association between the attending surgeon assistant categories and the complication rate using Fisher's Exact Test.

Tumor seeding across specialties: a systematic review.

Background: Understanding shared characteristics underlying reported tumor seeding episodes can reveal when tumor seeding is most likely to occur and guide clinical decision making. Our goal was to systematically review tumor seeding across specialties and determine what types of instrumentation and primary tumor histology are associated with tumor seeding.

Methods: A systematic review was conducted using PubMed and Web of Science, per PRISMA guidelines.

Comparison of a Novel Head-mounted Perimeter vs. the Humphrey Field Analyzer.

Purpose: Perimetry is a critical tool for the diagnosis and monitoring of glaucomatous visual field defects. The Humphrey Field Analyzer (HFA) is a large, relatively expensive device that does not normally allow for examination outside of the clinic, and it can be ergonomically difficult to tolerate for some patients. The present study compared the novel Smart System Virtual Reality (SSVR) perimetric headset test to that of the HFA in a group of patients with glaucoma.

The association between female sex and depression following traumatic brain injury: A systematic review and meta-analysis.

While women tend to experience more severe psychiatric and neurobehavioral symptoms following traumatic brain injury (TBI), the connection between sex and post-TBI depression remains poorly understood. To explore the potential association between sex and post-TBI depression, we conducted a systematic review and meta-analysis, including studies with participants who had no prior diagnosis of depression. Thirteen studies met the criteria for inclusion, collectively investigating a cohort of 449,471 individuals with TBI.

Critical Insights on Truthfully Reporting "Success Rates" in Modern Stroke Research: A Cautionary Tale.

In 2015, several trials confirmed the safety and efficacy of mechanical thrombectomy for acute ischemic stroke. These findings revolutionized acute ischemic stroke treatment and established mechanical thrombectomy as a standard of care. Subsequent studies have further validated that optimal clinical outcomes are closely associated with achieving higher grades of complete reperfusion and minimizing the number of retrieval attempts.

Readmission Rate, Predictors, Outcomes, and Burden of Readmission of Hepatorenal Syndrome in the United States: A Nationwide Analysis.

Background: Nationwide US data on readmission rates for patients with cirrhosis admitted with hepatorenal syndrome (HRS) is lacking. We reviewed 30-day readmission rates after HRS-related hospitalizations, the associated predictors of readmissions, and their impact on resource utilization and mortality in the United States.

Methods: We identified all adults admitted with HRS between 2016 and 2019 using the Nationwide Readmission database of the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project.

Transcultural Validation of the Five-Item Dry Eye Questionnaire for Indonesian Populations.

Purpose Indonesian dry eye (DE) disease (DED) prevalence data remain scarce, and Indonesian validations of the five-item Dry Eye Questionnaire (DEQ-5) are unavailable. We aimed to translate and validate an Indonesian language adaptation of the DEQ-5 (INDO-DEQ-5) for local populations. Methods Our observational study involved linguistic validation of the translation, reliability testing, dataset screening, and data collection through ophthalmic examinations and interviews.

Phenotypes and Trajectories of Tobacco-exposed Persons with Preserved Spirometry: Insights from Lung Volumes.

Among tobacco-exposed persons with preserved spirometry (TEPS), we previously demonstrated that different lung volume indices, specifically elevated total lung capacity (TLC) versus elevated ratio of functional residual capacity-to-TLC (FRC/TLC), identify different lung disease characteristics in the COPDGene cohort. Determine differential disease characteristics and trajectories associated with the lung volume indices among TEPS in the SPIROMICS cohort. We categorized TEPS (n=814) by tertiles (low, intermediate, high) of TLC or residual volume-to-TLC (RV/TLC) derived from baseline CT images, and then examined clinical and spirometric disease trajectories in mutually exclusive categories of participants with high TLC without high RV/TLC ([TLC]) versus high RV/TLC without high TLC ([RV/TLC]).

Functional evidence that S-nitroso-L-cysteine may be a candidate carotid body neurotransmitter.

The primary objective of the present study is to provide further evidence that the endogenous S-nitrosothiol, S-nitroso-L-cysteine (L-CSNO), plays an essential role in signaling the hypoxic ventilatory response (HVR) in rodents. Key findings were that (1) injection of L-CSNO (50 nmol/kg, IV) caused a pronounced increase in frequency of breathing (Freq), tidal volume (TV) and minute ventilation (MV) in naïve C57BL/6 mice, whereas injection of D-CSNO (50 nmol/kg, IV) elicited minimal responses; (2) L-CSNO elicited minor responses in (a) C57BL/6 mice with bilateral carotid sinus nerve transection (CSNX), (b) C57BL/6 mice treated neonatally with capsaicin (CAP) to eliminate small-diameter C-fibers, and (c) C57BL/6 mice receiving continuous infusion of L-CSNO receptor antagonists, S-methyl-L-cysteine and S-ethyl-L-cysteine (L-SMC + L-SEC, both at 5 μmol/kg/min, IV); and (3) injection of S-nitroso-L-glutathione (L-GSNO, 50 nmol/kg, IV) elicited pronounced ventilatory responses that were not inhibited by L-SMC + L-SEC. Subsequent exposure of naïve C57BL/6 mice to a hypoxic gas challenge (HXC; 10% O, 90% N) elicited pronounced increases in Freq, TV and MV that were subject to roll-off.

Outcomes of Adjunct Emergent Stenting Versus Mechanical Thrombectomy Alone: The RESCUE-ICAS Registry.

Background: Underlying intracranial stenosis is the most common cause of failed mechanical thrombectomy in patients with acute ischemic stroke with large vessel occlusion. Adjunct emergent stenting is sometimes performed to improve or maintain reperfusion, despite limited data regarding its safety or efficacy.

Methods: We conducted a prospective multicenter observational international cohort study.

Esophagitis in a Post-Liver Transplant Patient: A Case of Cytomegalovirus and Herpes Simplex Virus-1 Coinfection.

In post-liver transplant patients, esophagitis presents a diagnostic and management challenge due to the potential for opportunistic infections. This case describes a 59-year-old female with primary sclerosing cholangitis who underwent orthotopic liver transplantation six years prior. She presented with dysphagia, and her medical history included immunosuppression with prednisone, tacrolimus, and mycophenolate and a history of achalasia treated with esophageal peroral endoscopic myotomy.

Adjunctive Middle Meningeal Artery Embolization for Subdural Hematoma.

Background: Subacute and chronic subdural hematomas are common and frequently recur after surgical evacuation. The effect of adjunctive middle meningeal artery embolization on the risk of reoperation remains unclear.

Methods: In a prospective, multicenter, interventional, adaptive-design trial, we randomly assigned patients with symptomatic subacute or chronic subdural hematoma with an indication for surgical evacuation to undergo middle meningeal artery embolization plus surgery (treatment group) or surgery alone (control group).

Phase I study of allogeneic monocyte-derived inflammatory dendritic cells in combination with pembrolizumab.

PD-1 checkpoint inhibition has revolutionized the care of cancer. A small portion of patients with stage IV cancer achieve durable control. But, early progression is common and dramatic control is achieved for only a minority.
