Glucocorticoid receptor activation stimulates the sodium-chloride cotransporter and influences the diurnal rhythm of its phosphorylation.

The sodium-chloride cotransporter (NCC) in the distal convoluted tubule contributes importantly to sodium balance and blood pressure (BP) regulation. NCC phosphorylation determines transport activity and has a diurnal rhythm influenced by glucocorticoids. Disturbing this rhythm induces "nondipping" BP, an abnormality that increases cardiovascular risk.

Patient satisfaction and outcomes of partial wrist denervation in inflammatory arthritis.

Introduction: Inflammatory arthritis frequently affects the wrist, resulting in pain and disability. This study aims to investigate the long-term outcome of patients who underwent posterior interosseous nerve (PIN) denervation for inflammatory arthritis of the wrist.

Method: xForty consecutive wrists (36 patients) treated with PIN denervation were identified (mean follow-up 47 months; mean age 62.

Glucocorticoids Induce Nondipping Blood Pressure by Activating the Thiazide-Sensitive Cotransporter.

Blood pressure (BP) normally dips during sleep, and nondipping increases cardiovascular risk. Hydrochlorothiazide restores the dipping BP profile in nondipping patients, suggesting that the NaCl cotransporter, NCC, is an important determinant of daily BP variation. NCC activity in cells is regulated by the circadian transcription factor per1.
