100 patients over the age of 70 years underwent coronary angiography. The indications for this examination at this age were different from those in younger patients. After the age of 70 years, 58 per cent of coronary angiographies are performed as part of the haemodynamic survey of valvular disease. The risk of the examination appears to be higher, as two deaths occurred in this small series, while the mortality is estimated to be 2 per thousand in younger patients. Coronary angiography is very useful at this age in patients with valvular disease to determine the need for an associated coronary graft and also to determine contraindications for operation because of the severity of the lesions. A surgical indication was confirmed in 50 patients, but surgery was only performed in 36 of them. The follow-up of these patients demonstrates that patients operated for valvular disease had a longer survival that those considered to be inoperable or who refused operation. On the other hand, there was no difference in survival between grafted and non-operated patients over the age of 70 years.

Investigating Smartphone-Based Sensing Features for Depression Severity Prediction: Observation Study.

Background: Unobtrusively collected objective sensor data from everyday devices like smartphones provide a novel paradigm to infer mental health symptoms. This process, called smart sensing, allows a fine-grained assessment of various features (eg, time spent at home based on the GPS sensor). Based on its prevalence and impact, depression is a promising target for smart sensing.

Background: Nasal high flow (NHF) has been proposed to sustain high intensity exercise in people with COPD, but we have a poor understanding of its physiological effects in this clinical setting.
Research Question: What is the effect of NHF during exercise on dynamic respiratory muscle function and activation, cardiorespiratory parameters, endurance capacity, dyspnoea and leg fatigue as compared to control intervention.
Study Design And Methods: Randomized single-blind crossover trial including COPD patients.

Age-related lung function decline is associated with small airway closure and gas trapping. The mechanisms which cause these changes are not fully understood. It has been suggested that COPD is caused by accelerated ageing.

Introduction: Home care workers (HCWs) are paid caregivers who provide support to patients with chronic conditions and functional limitations. Additionally, they provide emotional support to patients and familial support. Although several qualitative studies have been conducted on HCWs, they focused more on studying prevalently the lived experiences about the workplace violence, the end of life, stressor and resilience, during the COVID-19 pandemic or focused more in dementia and heart failure, but not on feelings and working conditions.
