Dynamic and prognostic proteomic associations with FEV decline in chronic obstructive pulmonary disease.

Rationale: Identification and validation of circulating biomarkers for lung function decline in COPD remains an unmet need.

Objective: Identify prognostic and dynamic plasma protein biomarkers of COPD progression.

Methods: We measured plasma proteins using SomaScan from two COPD-enriched cohorts, the Subpopulations and Intermediate Outcomes Measures in COPD Study (SPIROMICS) and Genetic Epidemiology of COPD (COPDGene), and one population-based cohort, Multi-Ethnic Study of Atherosclerosis (MESA) Lung.

The PI3Kδ inhibitor zandelisib on intermittent dosing in relapsed/refractory follicular lymphoma: Results from a global phase 2 study.

In this global phase 2 study in patients with relapsed/refractory follicular lymphoma (FL), zandelisib was administered on intermittent dosing to mitigate immune-related adverse events and infections that have been reported with oral PI3Kδ inhibitors administered daily continuously. Eligible patients with measurable disease and progression after at least two prior therapies were administered zandelisib until disease progression or intolerability. The primary efficacy endpoint was objective response rate (ORR) and the key secondary efficacy endpoint was duration of response (DOR).

Contemporary view on the care of the rheumatoid wrist.

Rheumatoid arthritis (RA) is a common inflammatory condition that can lead to debilitating hand and wrist deformity. Since the introduction of disease-modifying antirheumatic drugs in the 1990s, the rate of surgery for rheumatoid arthritis has dramatically decreased 1. Nonetheless, surgical intervention remains an important tool in the management of patients with RA, and young surgeons must seek out expertise in this domain due to diminished exposure during their training.

The Association of Preoperative Bone Mineral Density and Outcomes after Anterior Cervical Discectomy and Fusion: A Systematic Review.

Study Design: This is a systematic review.

Objective: To evaluate anterior cervical discectomy and fusion (ACDF) outcomes and complications as a function of preoperative bone mineral density (BMD).

Summary Of Background Data: Preoperative BMD optimization is commonly initiated before lumbar spinal fusion, but the effects of BMD on ACDF are less known.

Breast Cancer Screening With Automated Breast US and Mammography vs Handheld US and Mammography in Women With Dense Breasts in a Real-World Clinical Setting.

Objective: We compared the performance of 2 breast cancer screening approaches, automated breast US (ABUS) with same-day mammography (ABUS/MG) and handheld US (HHUS) with same-day mammography (HHUS/MG), in women with dense breasts to better understand the relative usefulness of ABUS and HHUS in a real-world clinical setting.

Methods: In this institutional review board-approved, retrospective observational study, we evaluated all ABUS/MG and HHUS/MG screening examinations performed at our institution from May 2013 to September 2021. BI-RADS categories, biopsy pathology results, and diagnostic test characteristics (eg, sensitivity, specificity) were compared between the 2 screening approaches using Fisher's exact test.

PI3Kγ promotes neutrophil extracellular trap formation by noncanonical pyroptosis in abdominal aortic aneurysm.

Abdominal aortic aneurysm (AAA) is one of the most life-threatening cardiovascular diseases; however, effective drug treatments are still lacking. The formation of neutrophil extracellular traps (NETs) has been shown to be a crucial trigger of AAA, and identifying upstream regulatory targets is thus key to discovering therapeutic agents for AAA. We revealed that phosphoinositide-3-kinase γ (PI3Kγ) acted as an upstream regulatory molecule and that PI3Kγ inhibition reduced NET formation and aortic wall inflammation, thereby markedly ameliorating AAA.

Photoacoustic lifetime oxygen imaging of radiotherapy-induced tumor reoxygenation .

Purpose: Early detection and diagnosis of cancer is critical for achieving positive therapeutic outcomes. Biomarkers that can provide clinicians with clues to the outcome of a given therapeutic course are highly desired. Oxygen is a small molecule that is nearly universally present in biological tissues and plays a critical role in the effectiveness of radiotherapies by reacting with DNA radicals and subsequently impairing cellular repair of double strand breaks.

A novel animal model of symptomatic neuroma for assessing neuropathic pain.

Introduction: Following amputation, peripheral nerves lack distal targets for regeneration, often resulting in symptomatic neuromas and debilitating neuropathic pain. Animal models can establish a practical method for symptomatic neuroma formation for better understanding of neuropathic pain pathophysiology through behavioral and histological assessments. We created a clinically translatable animal model of symptomatic neuroma to mimic neuropathic pain in patients and assess sexual differences in pain behaviors.

Efficacy and safety of LAU-7b in a Phase 2 trial in adults with cystic fibrosis.

Background: Lung inflammation is associated with tissue damage in cystic fibrosis (CF). LAU-7b, a novel oral drug candidate, was shown to control inflammation and stabilize CFTR protein in the epithelial membrane during inflammatory stress in preclinical models of CF.

Methods: A double-blind, randomized, placebo-controlled Phase 2 study was conducted to evaluate efficacy and safety of LAU-7b in adults with CF.

Barriers and facilitators to effective electronic health record-based sepsis screening in the pediatric intensive care unit.

Introduction: The Pediatric Surviving Sepsis Campaign supports the implementation of automated tools for early sepsis recognition. In 2019 the C.S.

Detecting Early-Stage Pressure Injury in Patients With Dark Skin Tones Using an Enhanced Physical Assessment Technique and Halogen Lighting.

Purpose: The purpose of this quality improvement project was to identify stage 1 pressure injuries (PIs) in patients with darker skin tones using an enhanced skin assessment (Skin Assessment for Dark Skin, SADS) and halogen lighting.

Participants And Setting: This quality improvement project was conducted on 3 units at a large university teaching hospital in Southeast Michigan. The project was originally designed so that participating patients were identified by bedside nurses as having sufficient melanin to obscure blanching on the hand/forearm using regular lighting, but this goal was not met.

Does tamoxifen use increase the risk of endometrial cancer in premenopausal patients?

In a large, nationwide retrospective longitudinal cohort study that examined the occurrence of endometrial cancer and other uterine pathology in patients using tamoxifen for treatment of invasive breast cancer compared with breast cancer patients not receiving tamoxifen, the authors found with multiple previously published randomized controlled trials that demonstrated an increased risk of endometrial cancer in the postmenopausal population (but not in premenopausal patients). The experts suggest that

INFLAMMATORY RESPONSES TO POLYMICROBIAL INTRA-ABDOMINAL SEPSIS ARE HIGHLY VARIABLE BUT STRONGLY CORRELATED TO ENTEROBACTERIACEAE OUTGROWTH.

Sepsis is a common, heterogeneous, and frequently lethal condition of organ dysfunction and immune dysregulation due to infection. The causes of its heterogeneity, including the contribution of the pathogen, remain unknown. Using cecal slurry, a widely used murine model of intraperitoneal polymicrobial sepsis, as well as 16S ribosomal RNA sequencing and measurement of immune markers, we performed a series of translational analyses to determine whether microbial variation in cecal slurry composition (representing intra-abdominal pathogens) mediated variation in septic response.

Shared Decision-Making, Sphincter Preservation, and Rectal Cancer Treatment: Identifying and Executing What Matters Most to Patients.

Rectal cancer treatment often encompasses multiple steps and options, with benefits and risks that vary based on the individual. Additionally, patients facing rectal cancer often have preferences regarding overall quality of life, which includes bowel function, sphincter preservation, and ostomies. This article reviews these data in the context of shared decision-making approaches in an effort to better inform patients deliberating treatment options for rectal cancer.

Medically Tailored Meals for Patients With Cirrhosis and Hepatic Encephalopathy: The BRAINFOOD Proof-of-concept Trial.

Background And Aims: Guidelines recommend that patients with hepatic encephalopathy (HE) receive a high-protein diet (roughly 1 g/kg actual body weight). Concommitant sodium restriction, low health literacy, and food insecurity limit patients' ability to meet this goal. We aimed to determine the feasibility of home-delivered high-protein medically tailored meals (MTMs) for patients with a recent episode of overt HE.
