Evaluation of selected factors influencing sleep disorders in paramedics during the COVID-19 pandemic.

Introduction: Sleep disorders can develop as a result of exposure to stressors. The outbreak of the COVID-19 pandemic was an additional source of stress for paramedics, due to the fear of the unknown nature of the new pathogen. The main aim of this study was to identify factors influencing the development of sleep disorders among paramedics working during the COVID-19 pandemic.

Evaluation of Parameters Affecting the Occurrence of Systemic Inflammatory Response Syndrome in Patients Operated on Due to Kidney Tumors.

The application and prognostic nature of systemic inflammatory reaction syndrome (SIRS) is still being researched, as using SIRS parameters to predict patient status is cheap, efficient, fast, and easy. The study aimed to determine SIRS markers and postoperative complications occurrence in patients undergoing kidney tumor surgery, and to verify if SIRS occurrence depends on age, sex, BMI (body mass index), comorbidities, patients' general condition before the surgery, type of surgery, intraoperative blood loss, or intraoperative ischemia time. Body temperature, heart rate, respiratory rate, and leukocyte count were measured in patients ( = 285) operated on due to a kidney tumor on the first (T0) and third (T3) postoperative day.

Pathomechanisms of SARS-CoV-2 infection and development of atherosclerosis in patients with COVID-19: A review.

The pandemic of coronavirus disease 2019 (COVID-19) has posed a major health challenge for over 2 years. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes it belongs to single-stranded ribonucleic acid viruses and causes acute respiratory distress syndrome. The initial outbreak was discovered in December 2019 in Wuhan province, where SARS-CoV-2 quickly spread to other countries.

HOMOCYSTEINE AND CARDIOVASCULAR DISEASE - A CURRENT REVIEW.

Cardiovascular diseases remain the leading cause of death worldwide for the past 20 years. Of these, ischemic heart disease has the highest mortality rate. In over 98% of cases it is caused by atherosclerosis of the coronary arteries.

APELIN IN HEART FAILURE.

Apelin is a biologically active protein encoded by the APLN gene. It was first isolated in 1998 as a ligand for the APJ receptor. It exists in several isoforms differing in polypeptide chain length and biological activity.

Impact of Selected Sociodemographic and Clinical Parameters on Anxiety and Depression Symptoms in Paramedics in the Era of the COVID-19 Pandemic.

Introduction: The emergence of the SARS-CoV-2 virus, which caused the outbreak of the pandemic declared by the World Health Organization (WHO, World Health Organization) on 11 March 2020, has resulted in the introduction of many restrictions worldwide to contain the rapidly spreading pathogen. A particularly vulnerable professional group are paramedics working in Emergency Medical Teams.

Aim: The main aim of this study was to investigate the influence of selected sociodemographic and clinical parameters on anxiety and depression symptoms in paramedics during the COVID-19 pandemic.

EMOTIONAL PROBLEMS AND SLEEP DISTURBANCES IN PARAMEDICS IN THE ERA OF THE COVID-19 PANDEMIC.

Infectious diseases have accompanied mankind for centuries, and the effects of their dramatic course are felt on many levels of everyday life. The COVID-19 pandemic caused by SARS-CoV-2 virus infection carries a tremendous psychological burden for both those infected and health care workers. Particularly vulnerable to psychological strain are paramedics who have direct contact with and caring for patients infected with coronavirus.

Silica-protected micron and sub-micron capsules and particles for self-healing at the microscale.

A generalized silica coating scheme is used to functionalize and protect sub-micron and micron size dicyclopentadiene monomer-filled capsules and polymer-protected Grubbs' catalyst particles. These capsules and particles are used for self-healing of microscale damage in an epoxy-based polymer. The silica layer both protects the capsules and particles, and limits their aggregation when added to an epoxy matrix, enabling the capsules and particles to be dispersed at high concentrations with little loss of reactivity.

Plasma amino acid coatings for a conformal growth of titania nanoparticles.

We report on the conformal synthesis of ultrathin films from the amino acid histidine on flat silicon substrates and 3D periodic polymer structures via plasma enhanced chemical vapor deposition. We demonstrate the efficient utilization of this functional amino acid nanocoating for the formation of individual titania nanoparticles with dimensions from 2 to 15 nm depending upon reduction conditions. The titania nanoparticles were grown directly on histidine-functionalized planar and 3D polymer substrates by a wet-chemistry method that showed uniform surface coverage that reached approximately 75%.
