Treatment of metastatic rectal squamous cell carcinoma in a pregnant patient.

Rectal squamous cell carcinoma is an exceedingly rare form of rectal cancer, with limited data available regarding its presentation and effective treatment. Rectal cancer occurring during pregnancy is uncommon as well. This is a case of metastatic rectal squamous cell carcinoma presenting in a 22-week pregnant, female patient in her early 30s.

Exploring the effects of racial and socioeconomic factors on timeliness of lung cancer diagnosis and treatment in Baltimore Veterans.

Objectives: To characterize the effect of racial and socioeconomic factors on the timeliness of lung cancer diagnosis and treatment in a single-center Veterans Affair Medical Center (VAMC) pulmonary nodule clinic.

Methods: We conducted a single-center retrospective review of all patients seen at the Baltimore VAMC pulmonary nodule clinic between 2013 and 2019 to identify key demographic factors, measures of neighborhood socioeconomic disadvantage, cancer staging and histopathologic information, and time elapsed between diagnosis and treatment. We excluded patients with pulmonary nodules undergoing active surveillance, prior history of lung cancer, metastases of a different primary origin, insufficient followup, or who had received care outside the VHA system.

Sepsis and septic shock after craniotomy: Predicting a significant patient safety and quality outcome measure.

Objectives: Sepsis and septic shock are important quality and patient safety metrics. This study examines incidence of Sepsis and/or septic shock (S/SS) after craniotomy for tumor resection, one of the most common neurosurgical operations.

Methods: Multicenter, prospectively collected data from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database was used to identify patients undergoing craniotomy for tumor (CPT 61510, 61521, 61520, 61518, 61526, 61545, 61546, 61512, 61519, 61575) from 2012-2015.

FGF23 is endogenously phosphorylated in bone cells.

Levels of serum phosphate are controlled by the peptide hormone FGF23, secreted from bone osteocytes. Elevated levels of circulating FGF23 are a key factor in several hypophosphatemic disorders and play a role in chronic kidney disease. Posttranslational processing of FGF23 includes multi-site O-glycosylation, which reduces intracellular cleavage by proprotein convertases.
