Hypoglossal nerve stimulation increases airflow during sleep in obstructive sleep apnea
A new study found that hypoglossal nerve stimulation (HGNS) produces marked dose-related increases in airflow in OSA patients without arousing them from sleep. HGNS has been shown to eliminate inspiratory airflow limitation in the majority of patients, providing substantial relief of upper airway obstruction during sleep.

Genetic defect disturbs salt handling and pushes up blood pressure levels
Scientists from Max Planck Institute discover gene SLC4A5 responsible for sodium dysregulation and hypertension. The study found that a genetic defect in this gene can lead to excessive renal retention of sodium and water, resulting in abnormal blood pressure levels.
Patients with a wide range of autoimmune disorders have much greater risk of pulmonary embolism, and prophylaxis could be warranted
A study of over 500,000 patients in Sweden found that those with autoimmune disorders have a significantly increased risk of pulmonary embolism during the first year after admission, with some diseases carrying a higher risk than others. Prophylaxis may be warranted for these patients.
