TL;DR: The analysis showed that self-monitoring and self-management of oral coagulation is a safe option for suitable patients of all ages and patients should also be offered the option to self-manage their disease with suitable health-care support as back-up.

TL;DR: Through INR self-management, an improvement in the quality of ongoing oral anticoagulation could be shown and starting this form of therapeutic control early after mechanical heart valve replacement appears to effect a further reduction in antICOagulant-induced complications.

TL;DR: Survition in these selected young adult patients closely resembles that of the general population, possibly as a result of highly specialized anticoagulation self-management, better timing of surgery, and improved patient selection in recent years.
Abstract: Background—It is suggested that in young adults the Ross procedure results in better late patient survival compared with mechanical prosthesis implantation. We performed a propensity score–matched ...

TL;DR: Despite favourable effects of both diets on weight loss, the carbohydrate-reduced diet was more beneficial with respect to cardiovascular risk factors compared to the fat-reducing diet.
Abstract: We investigated whether macronutrient composition of energy-restricted diets influences the efficacy of a telemedically guided weight loss program. Two hundred overweight subjects were randomly assigned to a conventional low-fat diet and a low-carbohydrate diet group (target carbohydrate content: >55% energy and <40% energy, respectively). Both groups attended a weekly nutrition education program and dietary counselling by telephone, and had to transfer actual body weight data to our clinic weekly with added Bluetooth® technology by mobile phone. Various fatness and fat distribution parameters, energy and macronutrient intake, and various biochemical risk markers were measured at baseline and after 6, and 12 months. In both groups, energy intake decreased by 400 kcal/d compared to baseline values within the first 6 months and slightly increased again within the second 6 months. Macronutrient composition differed significantly between the groups from the beginning to month 12. At study termination, weight loss was 5.8 kg (SD: 6.1 kg) in the low-carbohydrate group and 4.3 kg (SD: 5.1 kg) in the low-fat group (p = 0.065). In the low-carbohydrate group, triglyceride and HDL-cholesterol levels were lower at month 6 and waist circumference and systolic blood pressure were lower at month 12 compared with the low-fat group (P = 0.005–0.037). Other risk markers improved to a similar extent in both groups. Despite favourable effects of both diets on weight loss, the carbohydrate-reduced diet was more beneficial with respect to cardiovascular risk factors compared to the fat-reduced diet. Nevertheless, compliance with a weight loss program appears to be even a more important factor for success in prevention and treatment of obesity than the composition of the diet.

TL;DR: From September 1987 to February 1994, 147 patients ranging between 11 and 82 years old with different mechanical circulatory support systems were treated, with the best survival rate achieved in group 2 with 72%, followed by group 1 with 44% and then group 3 with 28%.

TL;DR: This research presents a state-of-the-art online learning system that automates the very labor-intensive and therefore time-heavy and expensive and expensive process of manually cataloging and cataloging students' academic records.

TL;DR: The goal of therapy for bradycardia or tachycardia is to rapidly identify and treat patients who are hemodynamically unstable or symptomatic due to the arrhythmia.
Abstract: The goal of therapy for bradycardia or tachycardia is to rapidly identify and treat patients who are hemodynamically unstable or symptomatic due to the arrhythmia. Drugs or, when appropriate, pacing may be used to control unstable or symptomatic bradycardia. Cardioversion or drugs or both may be used to control unstable or symptomatic tachycardia. ACLS providers should closely monitor stable patients pending expert consultation and should be prepared to aggressively treat those with evidence of decompensation.
