Changes in plasma endocan level are related to circulatory but not respiratory failure in critically ill patients with COVID-19.

The aim of this prospective, observational study was to assess whether changes in the level of endocan, a marker of endothelial damage, may be an indicator of clinical deterioration and mortality in critically ill COVID-19 patients. Endocan and clinical parameters were evaluated in 40 patients with acute respiratory failure on days 1-5 after admission to the intensive care unit. Endocan levels were not related to the degree of respiratory failure, but to the presence of cardiovascular failure.

Alterations in Serum Concentration of Soluble CD163 within Five Study Days from ICU Admission Are Associated with In-Hospital Mortality of Septic Patients-A Preliminary Study.

Background: CD163, a cell membrane surface molecule specifically expressed by macrophages with an anti-inflammatory phenotype, participates in innate immunity. The purpose of the study was to evaluate the clinical utility of sCD163 in septic patients in comparison to other parameters associated with infections, mainly PCT, CRP and IL-18.

Methods: Serum samples were obtained from 40 septic patients on the ICU admission day, 3rd and 5th study days.

Intestinal Fatty Acid Binding Protein (I-FABP) as a Prognostic Marker in Critically Ill COVID-19 Patients.

Gastrointestinal symptoms are common in critically ill COVID-19 patients. There is currently no generally recognized method of assessing gastrointestinal injury in unconscious or sedated intensive care unit (ICU) patients. I-FABP (intestinal fatty acid binding protein) and citrulline have previously been studied as potential biomarkers of enterocyte damage in various gastrointestinal tract diseases, and changes in the levels of these markers may reflect intestinal wall damage in COVID-19.

An analysis of urine and serum amino acids in critically ill patients upon admission by means of targeted LC-MS/MS: a preliminary study.

Sepsis, defined as a dysregulated host response to infection, causes the interruption of homeostasis resulting in metabolic changes. An examination of patient metabolites, such as amino acids, during the early stage of sepsis may facilitate diagnosing and assessing the severity of the sepsis. The aim of this study was to compare patterns of urine and serum amino acids relative to sepsis, septic shock and survival.

Influenza in patients with respiratory failure admitted to intensive care units in Poland and the use of extracorporeal respiratory support: a survey-based multicenter study.

Background: In Poland, little is known about the most serious cases of influenza that need admittance to the intensive care unit (ICU), as well as the use of extracorporeal respiratory support.

Methods: This was an electronic survey comprising ICUs in two administrative regions of Poland. The aim of the study was to determine the number of influenza patients with respiratory failure admitted to the ICU in the autumn-winter season of 2018/2019.

Altered profiles of serum amino acids in patients with sepsis and septic shock - Preliminary findings.

Background: The clinical and diagnostic significance of systemic amino acids in sepsis and septic shock is unclear. Hence, the purpose of our study was to assess amino acids relationship with sepsis-related clinical data and to analyze whether they might have prognostic and discriminative value in sepsis and septic shock.

Materials And Methods: Prospective and observational study with 5-day follow-up.

Sepsis diagnosis and monitoring - procalcitonin as standard, but what next?

Sepsis is a life-threatening organ dysfunction caused by a systemic altered host response to infection. According to the newest guidelines the sepsis treatment should be personalized and based on an approach specified by use of biomarkers to tailor therapy to each patient's needs. The main features of such biomarkers should be high specificity, sensitivity and ability to monitor the progress of sepsis.

Interleukin-18 serum levels in sepsis: Correlation with disease severity and inflammatory markers.

Purpose: Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection and a syndrome shaped by pathogen and host factors with characteristic that evolve over time. The study was conducted to evaluate the prognostic and discriminative value of IL-18 assessment in comparison to PCT, CRP, WBC in early stage of sepsis and septic shock.

Methods: An observational and prospective study was conducted in the group of 40 ICU patients with diagnosis of sepsis or septic shock, serum PCT, IL-18, CRP and WBC measurements were performed on admission, and on the 2nd, 3rd and 5th therapy day.

Neutrophils, NETs, NETosis - old or new factors in sepsis and septic shock?

Neutrophils are an key part of the innate immune system in the host's defences against pathogens. Circulating neutrophils are recruited at the sites of infection or sterile inflammation in response to pathogen and host-derived inflammatory mediators. In addition to phagocytosis and degranulation, neutrophils display the release of NETs in order to restrain infection.

Platelets in sepsis - are there any new aspects?

Platelets display a number of properties besides the crucial function of repairing a damaged vascular endothelium and stopping bleeding. Platelets constitutively express molecules that are classically acknowledged to function in primary haemostasis. Platelets specialize in pro-inflammatory activities, and can secrete a large number of molecules, many of which display biological response modifier functions.

Coagulopathy in sepsis - a new look at an old problem.

Sepsis is a life-threatening condition characterized by a systemic response to microbial infection. Despite considerable progress in intensive care medicine, the incidence of sepsis and the number of sepsis-related deaths are increasing world-wide. There is a complex relationship between the coagulation, immune and inflammatory systems in sepsis.

Sepsis and septic shock-is a microcirculation a main player?

Shock, defined at a cellular level, is a condition in which oxygen delivery to the cells is not sufficient to sustain cellular activity and support organ function. The central role of microcirculation in providing oxygen to the cells makes it of prime importance in determining organ function. In sepsis and septic shock, macrocirculatory alterations and microcirculatory dysfunction participate concurrently in the pathophysiology of organ failure.

Procalcitonin kinetics - prognostic and diagnostic significance in septic patients.

Introduction: Severe sepsis and septic shock are advanced clinical conditions representing the patient's response to infection and having a variable but high mortality rate. Early evaluation of sepsis stage and choice of adequate treatment are key factors for survival. Some study results suggest the necessity of daily procalcitonin (PCT) monitoring because of its prognostic and discriminative value.

[Haemorrhagic shock complicating acute pancreatitis].

Background: Acute pancreatitis may be accompanied by a number of complications. They include diffuse peritonitis, intra-abdominal and retroperitoneal abscesses, and severe haemorrhage. These complications are the cause of approximately 50% of all deaths in acute pancreatitis.

End-of-life attitudes of intensive care physicians in Poland: results of a national survey.

Purpose: This study was designed to assess the ethical attitudes and practices of intensive care physicians regarding life-sustaining treatment in intensive care units (ICUs) in Poland.

Methods: A questionnaire was distributed to intensive care physicians taking part in a national medical congress. Participation in the study was voluntary and anonymous.

[Newborn-child of substance dependent mother--always actual problem].

The adverse effects on fetal development of alcohol and other drugs such as tobacco, psychostimulants and opioids are well known. Women who are pregnant or who may become pregnant are therefore a high priority for interventions to reduce drug use. Substances discussed in this article include the licit substances (alcohol and tobacco), illicit substances (opioids and other drugs), and prescription medication known for its misuse (benzodiazepines and barbiturates).

[A giant left atrial myxoma as a cause of a low cardiac output syndrome: a case report].

A case of a 75-year-old female with a giant left atrial myxoma (54 x 42 mm in transthoracic echocardiography) is presented. She remained in a stable condition, however, developed a low cardiac output syndrome shortly after echocardiographic examination. This was caused by tumour displacement from the atrial wall into the left ventricle.
