Effects of 3 months of detraining following cardiac rehabilitation in patients with atrial fibrillation.

Background: Atrial fibrillation negatively impacts physical fitness and health-related quality of life. We recently showed that 3 months of physiotherapist-led exercise-based cardiac rehabilitation improves physical fitness and muscle function in elderly patients with permanent atrial fibrillation and concomitant diseases. Little is, however, known about the consequences for physical fitness, physical activity level, and health-related quality of life after ending the rehabilitation period.

Preclinical Antitumor Activity and Biodistribution of a Novel Anti-GCC Antibody-Drug Conjugate in Patient-derived Xenografts.

Guanylyl cyclase C (GCC) is a unique therapeutic target with expression restricted to the apical side of epithelial cell tight junctions thought to be only accessible by intravenously administered agents on malignant tissues where GCC expression is aberrant. In this study, we sought to evaluate the therapeutic potential of a second-generation investigational antibody-dug conjugate (ADC), TAK-164, comprised of a human anti-GCC mAb conjugated via a peptide linker to the highly cytotoxic DNA alkylator, DGN549. The binding, payload release, and activity of TAK-164 was characterized motivating evaluation.

[Training in chronic heart failure to improve the quality of life].

Persons with chronic heart failure should be recommended aerobic and resistance exercise to be able to increase maximal oxygen uptake (VO2 max), walking distance, and health related quality of life (moderately strong scientific evidence - quality of evidence +++), and to reduce mortality and hospital admissions and increase muscle strength and endurance (low scientific evidence - quality of evidence ++). Prescription of exercise in chronic heart failure should always be preceded of assessments of aerobic and muscular fitness. The aerobic exercise could be conducted as continuous or interval exercise.

A group-based exercise program did not improve physical activity in patients with chronic heart failure and comorbidity: a randomized controlled trial.

Objective: To investigate how group-based exercise affects the levels of physical activity, physical fitness and health- related quality of life (HRQoL) in patients with chronic heart failure and comorbidities.

Design: Randomized controlled trial.

Patients: A total of 48 patients (10 women, 38 men), mean age 71 years (standard deviation 8 years), ejection fraction 27% (standard deviation 10%), and New York Heart Association functional class II-III.

4-(Pyrazol-4-yl)-pyrimidines as selective inhibitors of cyclin-dependent kinase 4/6.

Identification and structure-guided optimization of a series of 4-(pyrazol-4-yl)-pyrimidines as selective CDK4/6 inhibitors is reported herein. Several potency and selectivity determinants were established based on the X-ray crystallographic analysis of representative compounds bound to monomeric CDK6. Significant selectivity for CDK4/6 over CDK1 and CDK2 was demonstrated with several compounds in both enzymatic and cellular assays.
