It has been shown that patients admitted to high-volume hospitals for resection of sellar and parasellar lesions experience reduced mortality and morbidity. It remains unknown what preoperative factors influence admission to high-volume centers. We report a nationwide analysis of patients <18 years of age undergoing neurosurgical intervention for these lesions. A retrospective analysis of the Nationwide Inpatient Sample was performed with additional factors from the Area Resource File. International Classification of Diseases, 9th Revision diagnosis/procedural codes were used to identify patients undergoing resection of tumors from the pituitary gland or related structures. Patients >or=18 years old were excluded. Covariates included age, gender, race, and insurance status. Multivariate analysis was performed using multiple logistic regression models. A p value <0.05 was considered statistically significant. In total, 1,063 patients were identified. Most (69.8%) were seen at low-volume centers. Mean (median) patient age was 13.7 (15) years. The majority of patients were female (54.8%), white (61.9%), and insured (90.3%). Hispanics were 44% less likely (odds ratio (OR) 0.56, 95% confidence interval (CI) 0.34-0.92, p < 0.05) to b...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.
