Introduction: Maternal obesity (MO) increases the risk of gestational and neonatal complications. Bariatric surgery (BS) is currently the most effective long-term treatment of MO. The sustained weight loss after BS reduces the risk of maternal comorbidities during pregnancy. Nevertheless, BS is associated with an important risk of nutrients deficiency, and some data indicate that might increase the risk of prematurity and low birth weight. The objective of the present study is...

Background: Hyperparathyroidism jaw-tumor syndrome (HPT-JT) is a rare and underdiagnosed cause of familial primary hyperparathyroidism (incidence <1/1000000). It is caused by a pathogenic variant in the CDC73 (or HRPT2) gene that encodes parafibromin. Patients with HPT-JT have a 15–20% risk of developing parathyroid carcinoma. Other related conditions are jaw tumors in 30% of cases, kidney abnormalities in 15% of cases, and uterine tumors in 50% of c...
