Polyurethane-Based Porous Carbons Suitable for Medical Application.

The main aim of the study was to synthesize and analyze spectral data to determine the structure and stereometry of the carbon-based porous material internal structure. Samples of a porous biomaterial were synthesized through anionic polymerization following our own patent and then carbonized. The samples were investigated using MALDI ToF MS, FTIR ATR spectroscopy, optic microscopy, SEM, confocal laser scanning microscopy and CMT imaging.

Impact of sound levels and patient-related factors on sleep of patients in the intensive care unit: a cross-sectional cohort study.

Sleep disruption is common in patients in the intensive care unit (ICU). The aim of the study was to measure sound levels during sleep-protected time in the ICU, determine sources of sound, assess the impact of sound levels and patient-related factors on duration and quality of patients' sleep. The study was performed between 2018 and 2019.

Impact of Light Intensity on Sleep of Patients in the Intensive Care Unit: A Prospective Observational Study.

Aims And Objectives: Sleep deprivation in the intensive care unit (ICU) has been linked to numerous complications. Light levels might impact the sleep of patients in the ICU. The aim of the study was to measure light levels during sleep-protected time in the ICU and to assess the impact of light intensity on sleep quantity/quality.

Comparison of spirometric results obtained from the sitting and standing position in children participating in an epidemiological study.

Introduction: It is recommended that spirometric testing in children be completed while sitting. Our experience indicates that children prefer standing during spirometry.

Aim: We sought to compare spirometric results obtained from the sitting (SIP) and standing (STP) positions.

E-smoking among students of medicine - frequency, pattern and motivations.

Introduction: E-smoking has become a public health problem. The objectives of this study were to assess the prevalence of e-cigarette and tobacco cigarette use; to compare the patterns of smoking; to assess the attitudes and motivations for e-cigarette use.

Material And Methods: All 1,700 students from Faculty of Medicine (Medical University of Silesia) were invited to questionnaire based cross-sectional study about the frequency and attitudes towards the use of traditional and electronic cigarettes.

[Assessment of the response of peripheral blood mononuclear leukocytes on Helicobacter pylori infection in children].

In the study the proliferative response of peripheral blood mononuclear leukocytes (PBML) from children with chronic dyspepsia (chr. d) to H.p.

Helicobacter pylori lipopolysaccharide in the IL-2 milieu activates lymphocytes from dyspeptic children.

In this study, we assessed the proliferative response of peripheral blood mononuclear leukocytes (PBML) from 33 children/young adolescents with chronic dyspepsia, to H. pylori LPS in the presence and absence of IL-2 as a T cell growth factor. A rapid urease test (RUT) and a presence of Helicobacter-like organisms (HLO) in the biopsy specimens allowed us to distinguish RUT/HLO-positive (17/33) and -negative (16/33) patients.
