[Functional recovery in older inpatients with hypertension and ischemic heart disease post-COVID-19.].

Understanding the recovery process of functional abilities post-COVID-19 in older inpatients with arterial hypertension and ischemic heart disease is important for optimising healthcare delivery and resources. Participants in this study were individuals undergoing hospital-based rehabilitation following COVID-19 (average age 66, n=183). They were categorised into groups with arterial hypertension (n=92), ischemic heart disease (n=18), both conditions (n=38), and a control group without these diseases (n=35).

Haemostatic chitosan coated gauze: in vitro interaction with human blood and in-vivo effectiveness.

Background: Chitosan and its derivates are widely used for biomedical application due to antioxidative, anti-inflammatory, antimicrobial and tissue repair induced properties. Chitosan-based materials also used as a haemostatic agent but influence of different molecular weight and concentration of chitosan on biological response of blood cells is still not clear. The aim of this research was to evaluate interaction between human blood cells and various forms of chitosan-based materials with different molecular weight and chitosan concentration and prove their effectiveness on in-vivo model.

[Psychophysiological aspects of duodenal ulcer in young patients].

SMALL and Spilberg-Khanin questionnaires were used to examine psychological state while statistical and spectral analysis of heart rate at rest and orthostasis to evaluate vegetative status in 86 patients aged 15-24 years with duodenal ulcer (DU). Patients with mild DU had the least psychological and vegetative alterations primarily of the neurotic trend with a relative enhancement of the nervous sympathetic component. A severe disease was characterized by the greatest psychovegetative changes--high SMALL scales, anxiety, stress of the vegetative nervous systems at rest and orthostasis.
