[The Rezūm system in the treatment of male lower urinary tract symptoms (LUTSs) due to benign prostatic obstruction (BPO)].

Aktuelle Urol 2018 Dec 6;49(6):519-524. Epub 2018 Dec 6.

Spital Thurgau AG, Urologie, Frauenfeld.

The classical algorithm of the management of male lower urinary tract symptoms (LUTSs) due to benign prostatic hyperplasia (BPH) includes a surgical approach in case pharmacological therapy has failed. Emerging minimally-invasive treatments (MITs) offer potential for rapid symptomatic relief, reducing the morbidity of invasive BPH surgery. Convective interstitial radiofrequency water vapour thermal ablation of the prostate with the Rezūm system is a novel MIT for the treatment of bothersome moderate-to-severe lower urinary tract symptoms associated with BPH.

Headache in Pregnancy, the Puerperium, and menopause.

Semin Neurol 2018 Dec 6;38(6):627-633. Epub 2018 Dec 6.

Department of Neurology, University at Buffalo School of Medicine and Biomedical Sciences, The State University of New York, Buffalo, New York.

Headache is a neurologic disorder that displays gender dichotomy. It is well established that there is a strong link between migraine headache and sex hormones, specifically estrogen, which influences the severity of migraines during the menstrual cycle, pregnancy, and menopause. Furthermore, the epidemiology of headaches during pregnancy and the postpartum period is very distinct from that in males or nonpregnant females, in part due to the hemodynamic and hematologic changes that occur during pregnancy.

Tracking Arteriovenous Fistula Maturation: A Novel Approach.

Blood Purif 2018 Dec 6:1-6. Epub 2018 Dec 6.

Renal Research Institute, New York, New York, USA.

Background: The time between the creation of an arteriovenous fistula (AVF) and its successful use is significantly longer in hemodialysis (HD) patients in the United States compared to those in other countries, and there is an urgent need to reduce the residence time of central-venous catheters (CVC).

Methods: Successful AVF creation and maturation results in typical hemodynamic changes, such as an increase in cardiac output and upper body blood flow (UBBF). In patients with CVC as vascular access, we measured once per minute intradialytic central-venous oxygen saturation (ScvO2) and hemoglobin levels simultaneously using the Crit-Line Monitor.

Hot spots for GPCR signaling: lessons from single-molecule microscopy.

Curr Opin Cell Biol 2018 Dec 3;57:57-63. Epub 2018 Dec 3.

Institute of Pharmacology and Bio-Imaging Center, University of Würzburg, Germany.

G protein-coupled receptors (GPCRs) are among the best-studied membrane receptors, mainly due to their central role in human physiology, involvement in disease and relevance as drug targets. Although biochemical and pharmacological studies have characterized the main steps in GPCR signaling, how GPCRs produce highly specific responses in our cells remains insufficiently understood. New developments in single-molecule microscopy have made it possible to study the protein-protein interactions at the basis of GPCR signaling in previously inconceivable detail. Read More

Longer schooling but not better off? A quasi-experimental study of the effect of compulsory schooling on biomarkers in France.

Soc Sci Med 2018 Nov 23;220:379-386. Epub 2018 Nov 23.

Department of Social and Behavioral Sciences, Harvard T H Chan School of Public Health, 677 Huntington Ave, Boston, MA, 02115, USA; CUNY Graduate School of Public Health and Health Policy, 205 East 42nd Street, New York, NY, 10017, USA.

Less schooling is associated with increased biological risks for chronic disease, but whether increasing years of schooling through policy interventions reduces these risks remains unclear. We examine the effect of a major education reform introduced in 1959 that raised the minimum school leaving age from 14 to 16 years in France, offering a unique natural experiment. We assess the causal impact of increased schooling duration on 16 biomarkers of cardiovascular, metabolic, organ and immune function in a large cohort of men and women born around 1953. Read More
