The link between elevated heart rate and cardiovascular events is established in healthy individuals and in patients with cardiovascular disease. The new agent, ivabradine, specifically and selectively inhibits the I(f) current, with the sole action of heart rate reduction, with no impact on any other cardiac parameters. The benefits of "pure" heart rate reduction with ivabradine have been the focus of one of the largest clinical development programs ever performed, involving >20,000 individuals. Ivabradine has anti-ischemic and antianginal efficacy in monotherapy, as well as in combination with other antianginals, such as beta-blockers, and is safe and well tolerated. Two major morbidity-mortality trials, BEAUTIFUL and SHIFT, showed that heart rate reduction with ivabradine dramatically improves prognosis in patients with coronary artery disease and left ventricular dysfunction, symptomatic angina, or chronic heart failure. The development of ivabradine represents a clear innovation in the management of cardiovascular disease.

Association of systemic immune-inflammation index (SII) with risk of psoriasis: a cross-sectional analysis of National Health and Nutrition Examination Survey 2011-2014.
Eur J Med Res

The Department of Pediatrics, The Third Xiangya Hospital of Central South University, Changsha, 410013, Hunan, China.
Background: The systemic immune-inflammation index (SII) is an emerging marker of inflammation, and the onset of psoriasis is associated with inflammation. The aim of our study was to investigate the potential impact of SII on the incidence rate of adult psoriasis.
Methods: We conducted a cross-sectional study based on the National Health and Nutrition Examination Survey (NHANES) 2011-2014 data sets.

Unobtrusive pulse rate monitoring by continuous video recording, based on remote photoplethysmography (rPPG), might enable early detection of perioperative arrhythmias in general ward patients. However, the accuracy of an rPPG-based machine learning model to monitor the pulse rate during sinus rhythm and arrhythmias is unknown. We conducted a prospective, observational diagnostic study in a cohort with a high prevalence of arrhythmias (patients undergoing elective electrical cardioversion).

Background: Unicortical plate fixation offers several theoretical advantages in the treatment of metacarpal shaft fractures compared to bicortical fixation. This approach avoids the potential hazard of excessive drilling into the volar cortex, thus minimizing damage to surrounding soft tissues and helping prevent complications related to improperly sized screws. These benefits prompted our team to conduct a preliminary clinical study to investigate the effectiveness and safety of this approach.
