Objective: To determine the heart rate response to repetitive lifting of light weights employing two techniques, stoop and squat.
Design: Randomized cross-over trial.
Participants: Twenty healthy volunteers (11 women, 9 men), mean age of 25 years, recruited from the staff of a physical medicine and rehabilitation department.
Methods: Subjects lifted and lowered a box weighing 0, 1, or 3 kg, using the stoop (bent at waist with knees straight) and squat (knees bent) techniques, 20 times in 1 minute.
Main Outcome Measures: The heart rate was recorded every 5 seconds during the effort aid 30 seconds and 1 minute after the test.
Results: Significantly higher heart rates were found during both the test and recuperation phases of the squat technique with each of the three loads (p < .05). The heart rate increase was also higher with the 3 kg load than with the 1 kg or 0 kg load (p = .0001).
Conclusion: The heart rate is lower using the stoop technique for lifting. This may explain why individuals choose the more ergonomically risky stoop technique in everyday lifting tasks.

Background: Mobile health apps have shown promising results in improving self-management of several chronic diseases in patients. We have developed a mobile health app (Cardiomeds) dedicated to patients with heart failure (HF). This app includes an interactive medication list; daily self-monitoring of symptoms, weight, blood pressure, and heart rate; and educational information on HF delivered through various formats.

Little is known about the effects of sodium-glucose co-transporter 2 inhibitors (SGLT2i) on atherosclerosis. We aimed to determine if a 90-day intake of Dapagliflozin could improve atherosclerosis biomarkers (namely endothelial function assessed by flow-mediated dilatation [FMD] and carotid intima-media thickness [CIMT]) in diabetic and non-diabetic acute coronary syndrome (ACS) patients when initiated in the early in-hospital phase. ATH-SGLT2i was a prospective, single-center, observational trial that included 113 SGLT2i naive patients who were admitted for ACS and who were prescribed Dapagliflozin at a fixed dose of 10 mg during their hospital stay for either type 2 diabetes or for heart failure.

Importance: Surgeon stress can influence technical and nontechnical skills, but the consequences for patient outcomes remain unknown.
Objective: To investigate whether surgeon physiological stress, as assessed by sympathovagal balance, is associated with postoperative complications.
Design, Setting, And Participants: This multicenter prospective cohort study included 14 surgical departments involving 7 specialties within 4 university hospitals in Lyon, France.

Physiological responses derived from audiovisual perception during assisted driving are associated with the regulation of the autonomic nervous system (ANS), especially in emergencies. However, the interaction of event-related brain activity and the ANS regulating peripheral physiological indicators (i.e.

Cardiac computed tomography angiography (CTA) is a valuable tool in the assessment of congenital and acquired cardiac disease in children. The goal of cardiac CTA is to produce images that are free of motion and provide sufficient characterization of the anatomy in question. Given the complexity of pediatric patient characteristics, including patient size, heart rate, breath-holding capability, and variant anatomy, cardiac CTA technique must be individualized to the patient as well as the indication to answer the clinical question while also minimizing radiation exposure.
