The article presents the general construction of an underwater vehicle manipulator along with a discussion of the materials used in their construction. The types of drive systems used by the manipulator have been characterised, distinguishing their advantages and disadvantages. The functions of the manipulator are specified in relation to the activities performed by it. Moreover, the paper discusses the manipulator's degrees of freedom with the specification of the formula for their calculation. The basic types of end effectors are presented as well as an outline of the classification of manipulators in relation to the tasks carried out.

This work is a preliminary pilot research aiming at defining the role of the Piechcin Diving Centre in the development of specialised tourism. Particular attention was paid to the various elements defining the quality of the services offered. The key aspects and reasons for which respondents visit the centre were also determined. Both the customer’s expectations of the organiser of this form of recreation were analysed, and research was made to help understand whether the time the customers spends at the centre facilitates a positive decision regarding the participation in diving trips in larger bodies of water, with particular consideration of the Baltic Sea. Different forms of cooperation between the centre and regional authorities in terms of promoting the region were also reviewed.

Hyperbaric oxygen toxicity studies were conducted on rabbits using the opsonic index determination.The study was conducted on 15 animals that had opsonin index examined prior to hyperbaric oxygen exposure. They were then subjected to an hourly exposure to hyperbaric oxygen with overpressure values of 1.8, 2.4 and 3.1 atm in groups of 5 animals. After the exposure, the opsonium index was re-examined upon the lapse of 1, 2 and 10 days. Parallelly, the morphological image of the blood was examined.There was a statistically significant increase in the index in the first two days after exposure, independent of the value of oxygen overpressure. On the 10th day, the index value approached the initial one.

This paper presents a case report of a patient with a diagnosed complication of a sternum wound which was treated using hyperbaric oxygen, emphasizing the truism of the benefits of combined surgical therapy, antibiotic therapy and oxybarotherapy.

The most hazardous adverse reactions following hyaluronic acid injections in aesthetic medicine involve vascular complications, known as the Nicolau Syndrome. This article presents a vascular complication in the area of the upper part of the nasolabial fold following subcutaneous administration of 0.5 ml of hyaluronic acid. At the time of the injection, paling occurred, which was followed by livedo racemosa appearing an hour later. Upon the lapse of a week, an ulceration appeared. It was not until the tenth day after the hyaluronic acid injection that hyaluronidase was administered. After 15 hyperbaric oxygen exposures, the ulcer was completely healed
This article presents a description of the water cooling system in the pool of the "Kobuz" decompression chamber constituting a part of the DGKN-120 hyperbaric simulator used at the Department of Underwater Works Technologies of the Naval Academy in Gdynia.

To help general practitioners (GPs) in early identification of patients with palliative care (PC) needs, this pilot study aimed to determine the potential of the combined original surprise question (SQ1) (‘Would I be surprised if this patient died within the next 12 months?’) and the second surprise question (SQ2) (‘Would I be surprised if this patient was still alive after 12 months?’). We hypothesized that answering these SQs would trigger them to make a multidimensional care plan.
26 Slovenian GPs, randomized into 4 groups, were invited to write a care plan for each of the four patients described in case vignettes (2 oncologic, 1 organ failure and 1 frailty case). GPs in group 1 were only asked to write a care plan for each patient. GPs in group 2 answered SQ1 and GPs in groups 3 and 4 answered SQ1 and SQ2 before writing the care plan. The type and number of PC aspects mentioned in the respective care plans were quantified into a numeric RADboud ANTicipatory (RADIANT) score.
Mean RADIANT scores in groups 1-4 were 2.2, 3.6, 2.5 and 3.1, respectively. When comparing the different vignettes, vignette B (terminal oncologic patient) scored best (3.6). Mean RADIANT scores in groups 3 and 4 were slightly higher for GPs who would be surprised compared to GPs who would not be surprised if the patient was still alive in 12 months.
The combined SQs were considered helpful in the early identification of patients in need of PC in Slovenian general practice.

To examine the effects of various maternal and neonatal perinatal factors on the child’s body mass index (BMI) and physical fitness at school-age.
Data from two registries, the SLOfit database (a national surveillance system of children’s motor and physical development) and Slovenian National Perinatal Information System (NPIS) were analysed. Perinatal data for 2,929 children born in 2008 were linked to results of SLOfit testing of these children in 2016. Linear regression analysis was used to assess the potential relationship between several perinatal factors (very preterm birth, birth mass, maternal age, hypertensive disorders of pregnancy, gestational diabetes, parity, plurality, maternal pre-pregnancy BMI, mode of delivery, presentation, Apgar score at 5 minutes, and admission to a neonatal intensive care unit (NICU)) and child’s BMI or child’s physical fitness index (PFI) at the age of eight years. We also included child’s school grade and maternal educational level in the analysis. A p value <0.05 was considered statistically significant.
Children born to mothers with lower pre-pregnancy BMI and higher education had lower BMI and higher PFI (p<0.001) at school-age. Physical fitness was also inversely associated with nulliparity (p<0.001) and NICU admission (p=0.020).
Among all perinatal factors studied, higher maternal education and lower pre-pregnancy BMI seem to be the most significant determinants of child’s BMI and physical fitness at school-age.
To deliver quality management of a frail individual, a clinician should understand the concept of frailty, be aware of its epidemiology and be able to screen for frailty and assess it when it is present, and, finally, to recommend successful interventions.
A systematic literature search was conducted in the following databases: PubMed, Cochrane, Embase, Cinahl and UpToDate. The criterion in selecting the literature was that articles were published in the period from 2002 to 2017. From 67432 initial hits, 27 publications were selected.
Useful interventions to address frailty are supplementation of vitamin D, proper nutrition, multicomponent training, home-based physiotherapy and comprehensive geriatric assessment, particularly when performed in geriatric wards.
Comprehensive geriatric assessment is an effective way to decrease frailty status especially when performed in geriatric wards. Multicomponent physical training and multidimensional interventions (physical training, nutrition, vitamin D supplementation and cognitive training) are effective measures to reduce frailty.

There is currently a strong scientific evidence about the negative health consequences of physical inactivity. One of the potential tools for promoting physical activity at the institutional level of the Ecological model is to create conditions and settings that would enable pupils, students and employees engage in some form of physical activity. However, physical activities as a subject are being eliminated from the study programs at Slovak universities. The purpose of the study was to find current evidence about the level of structured physical activity and health-related variables in university students in Košice.
Material and methods
The sample consisted of 1,993 or, more precisely, 1,398 students who attended two universities in Košice. To collect data, students completed a questionnaire and were tested for body height, body weight, circumferential measures and percentage body fat.
The university students did not sufficiently engage in a structured physical activity. A large number of students had either low or high values of percentage body fat and BMI and high WHR values.
Our findings have shown that the research into physical activity of university students should receive more attention.
