Comparison of immune responses to respiratory syncytial virus in infancy, childhood, and adulthood using an in vitro model of human respiratory infection.

Respiratory syncytial virus (RSV) is a major contributor to morbidity and mortality in infants. We developed an in vitro model of human respiratory infection to study cellular immune responses to RSV in infants, children, and adults. The model includes human lung epithelial A549 cells or human fetal lung fibroblasts infected with a clinical strain of RSV at a multiplicity of infection of 0.

Electrochemical Aptamer-Based Biosensor for Detecting Pap31, a Biomarker for Carrion's Disease.

Carrion's disease, caused by infection with the bacterium (), is effectively treated with antibiotics, but reaches fatality rates of ~90% if untreated. Current diagnostic methods are limited, insufficiently sensitive, or require laboratory technology unavailable in endemic areas. Electrochemical aptamer-based (E-AB) biosensors provide a potential solution for this unmet need, as these biosensors are portable, sensitive, and can rapidly report the detection of small molecule targets.

Risk of Thromboembolism in Patients Receiving Immunotherapy-Based Combinations as Front-Line Therapy for Metastatic Renal Cell Carcinoma.

Background: Most patients with treatment-naïve metastatic renal cell carcinoma (mRCC) receive combination-based immunotherapy with either 2 immune-oncology checkpoint inhibitors (IO/IO) or an IO agent in combination with a vascular endothelial growth factor receptor (VEGF-R) tyrosine kinase inhibitor (IO/TKI). The rates of thromboembolism (TE) in these cohorts are not clearly described and can potentially impact decision-making between IO/IO and IO/TKI.

Methods: We conducted a retrospective investigation of patients with treatment-naïve mRCC treated with IO-based combinations between January 2015 and April 2021 at the Cleveland Clinic.

Inflammation, lipid dysregulation, and transient receptor potential cation channel subfamily V member 4 signaling perpetuate chronic vulvar pain.

Localized provoked vulvodynia is characterized by chronic vulvar pain that disrupts every aspect of the patient's life. Pain is localized to the vulvar vestibule, a specialized ring of tissue immediately surrounding the vaginal opening involved in immune defense. In this article, we show inflammation is the critical first step necessary for the generation of pain signals in the vulva.

Association of program-specific variation in bariatric surgery volume for Medicaid patients and access to care: a tale of inequality?

Background: Although patients with lower socioeconomic status are at higher risk of obesity, bariatric surgery utilization among patients with Medicaid is low and may be due to program-specific variation in access. Our goal was to compare bariatric surgery programs by percentage of Medicaid cases and to determine if variation in distribution of patients with Medicaid could be linked to adverse outcomes.

Methods: Using a state-wide bariatric-specific data registry that included 43 programs performing 97,207 cases between 2006 and 2020, we identified all patients with Medicaid insurance (n = 4780, 4.

Evaluating outcomes among surgeons who changed their technique for gastric bypass: a state-wide analysis from 2011 to 2021.

Differentiating Human Pluripotent Stem Cells to Cardiomyocytes Using Purified Extracellular Matrix Proteins.

Human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) can be differentiated into cardiomyocytes (hESC-CMs and iPSC-CMs, respectively), which hold great promise for cardiac regenerative medicine and disease modeling efforts. However, the most widely employed differentiation protocols require undefined substrates that are derived from xenogeneic (animal) products, contaminating resultant hESC- and iPSC-CM cultures with xenogeneic proteins and limiting their clinical applicability. Additionally, typical hESC- and iPSC-CM protocols produce CMs that are significantly contaminated by non-CMs and that are immature, requiring lengthy maturation procedures.
