Aim. To investigate the state of systemic hemodynamics (SHD) in young people to assess the potential impact of its disorders in the formation of arterial hypertension (AH) and to carry out preventive measures.Methods. A random sample of 91 young people from 17 to 25 years old was examined; 27 of them were men (average age 23.7±1.6 years) and 64 women (average age 20.4±1.1 years). The study involved clinical residents and students who, according to preliminary and periodic medical examinations, excluded the presence of cardiovascular diseases. The indicators of SHD were investigated by the method of volumetric compression oscillometry using a portable automated software and hardware complex for non-invasive research of central hemodynamics (Device “CAP TsG osm-“Globus”).Results. AH was detected in 4.4%; “white coat” AH in 8.79%; arterial hypotension – in 5.49%. In individuals with normal blood pressure (BP) (75 people), an increase in specific peripheral vascular resistance was most often revealed in 30.6%. An unchanged hemodynamic profile in the group with a normal BP level was recorded only in 28.0% of the examinees.Conclusion. The obtained results indicate that even among “healthy” young people aged 18- 25 years with a normal BP level, the proportion of people with impaired SHD values is 72%. People with hypertension and with altered SHD indicators should be included in the regular medical check-up observation group.

The Impact

Introduction. In the modern world, the introduction of digital technologies in healthcare is one of the priorities of development, which opens up a wide range of opportunities from screening and monitoring to various health disorders. In 2020 we completed the work to evaluate the applied capabilities of contactless videoplethysmography based on the telemetric control system developed by us and patented using the DISITA software and hardware complex during pre-trip post-trip medical examinations in 19 drivers of passenger vehicles. The study aims to explore the possibilities of the data of variational heart rate monitoring using reflected video plethysmography in assessing drivers' performance in their work. We have identified the most sensitive and significant heart rate variability indicators that reflect the professional load's impact. Materials and methods. We carried out during the usual pre-trip examination, video plethysmography of the skin of the face of the subjects in parallel in conditions of both natural daylight and typical artificial lighting of medical and diagnostic rooms, at a distance of the recording WEB camera of the DISITA software and hardware complex from the face of the subject within 40-70 cm. Researchers examined the methodological recommendations developed by the Izmerov Research Institute of Occupational Health team and RT-Medicine JSC. Results. We use videoplethysmography to evaluate variational heart rate monitoring as a method for assessing functional states during mass pre-trip (pre-shift) and post-trip (post-shift) medical examinations. In this case, the heart rate estimated by palpation was identical to the heart rate obtained by videoplethysmography. The most sensitive parameters characterizing the impact of professional load on drivers were changes in the indicators of variational heart rate monitoring: SDNN, RMSSD, CV, TR, HF, LF, and the waves of vasomotion regulation. Conclusions. Videoplethysmography with an assessment of the data of variational heart rate monitoring can be used to predict the functional state (stability of the body) of drivers in the course of their professional activities.

Abstract Background Most psychiatric disorders have their onset in childhood or adolescence, and if not fully treated have the potential for causing life-long psycho-social and physical sequelae. Effective psychotherapeutic and medication treatments exist, but a significant proportion of children and young people do not make a full recovery. Thus, novel, safe, brain-based alternatives or adjuncts to conventional treatments are needed. Repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) are non-invasive brain stimulation (NIBS) techniques which have shown clinical benefits in adult psychiatric conditions. However, in children and young people their efficacy is not well established. The objective of this study will be to systematically evaluate the evidence on clinical effects of NIBS in children and young people with psychiatric disorders, assessing disorder-specific symptoms, mood and neurocognitive functions. Methods We designed and registered a study protocol for a systematic review. We will include randomised and non-randomised controlled trials and observational studies (e.g. cohort, case-control, case series) assessing the effects of NIBS in children and young people (aged ≤ 24 years old) for psychiatric disorders. The primary outcome will be reduction of disorder-specific symptoms. Secondary outcomes will include effects on mood and cognition. A comprehensive search from database inception onwards will be conducted in MEDLINE, EMBASE and PsycINFO. Grey literature will be identified through searching multiple clinical trial registries. Two reviewers will independently screen all citations, full-text articles and abstract data. The methodological quality of the studies will be appraised using appropriate tools. We will provide a narrative synthesis of the evidence and according to heterogeneity will conduct an appropriate meta-analysis. Additional analyses will be conducted to explore the potential sources of heterogeneity. Discussion This systematic review will provide a broad and comprehensive evaluation of the evidence on clinical effects of NIBS in children and young people with psychiatric disorders. Our findings will be reported according to the PRISMA guidelines and will be of interest to multiple audiences (including patients, researchers, healthcare professionals and policy-makers). Results will be published in a peer-reviewed journal. Systematic review registration PROSPERO CRD42019158957

We have studied the effects of normal aging on visual attention. Have participated a group of 38 healthy elderly people with an average age of 67.8 years and a group of 39 healthy young people with average age of 19.2 years. In a first experiment of visual detection, response times were recorded, with and without covert attention, to the presentation of stimuli (0.5º in diameter grey circles) appearing in three eccentricities (2.15, 3.83 and 5.53° of visual field) and with three levels of contrast (6, 16 and 78%). In a second experiment of visual form discrimination circles and squares with the same features as in the previous experiment were presented, but in this case subjects only should respond to the emergence of the circles. In both age groups, the covert attention reduced response times. Compared to young people, the older group achieved better results in some aspects of attention tests and response times were reduced more in the stimuli of greater eccentricity. The data suggest that there is a mechanism of adaptation in aging, in which visual attention especially favors the perception of those stimuli more difficult to detec

Abstract Background The retinal microvasculature offers unique non-invasive evaluation of systemic microvascular abnormalities. Previous studies reported associations between retinal microvascular parameters (RMPs) and diabetes. The aim of this study was to assess associations between RMPs and diabetes in a cross-sectional analysis of older persons from the Northern Ireland Cohort for the Longitudinal Study of Ageing (NICOLA). Methods RMPs (central retinal arteriolar/venular equivalents, arteriolar to venular ratio, fractal dimension, and tortuosity) were measured from optic disc-centred fundus images using semi-automated software. Associations were assessed between RMPs and diabetes status with adjustment for potential confounders. Results Data were included for 1762 participants with 209 classified as having diabetes. Participants had a mean age of 62.1 ± 8.5 years, and 54% were female. As expected, participants with diabetes had significantly higher mean glycated haemoglobin A1c compared to participants without diabetes (57.4 ± 17.6 mmol/mol versus 37.0 ± 4.2 mmol/mol, respectively). In unadjusted and minimally adjusted regression, arteriolar to venular ratio, arteriolar tortuosity and venular tortuosity were significantly associated with diabetes (minimally adjusted odds ratio [OR] = 0.85; 95% confidence intervals [CIs] 0.73, 0.99; P = 0.04, OR = 1.18; 95% CI 1.02, 1.37; P = 0.03 and OR = 1.20; 95% CI 1.04, 1.38; P = 0.01, respectively), although all failed to remain significant following adjustment for potential confounders. No additional associations between other RMPs and diabetes were detected. Conclusion Despite previously reported associations between diabetes and RMPs, our study failed to corroborate these associations in an older community-based cohort.

Based on the experience gained with a single clinical observation, the author concludes that the sudden death of healthy young people during swimming is in some cases due to shock caused by the absorption of toxic amounts of H-substants (histamine), which are released in the overly sensitive skin due to cooling.
