The significance of glycocalyx in surgery.

Introduction: Surgical treatment is associated with an unwanted response of the organism to the so-called surgical trauma. This response is called surgical stress. Ischaemia-reperfusion injury is one of essential causes of tissue damage.

Peripheral vascular trauma - basic management, diagnosis and treatment.

Introduction: Peripheral vascular injuries occur in 1-3% of all traumas in civilian settings. The management of these injuries is often based on experience derived from war medicine where these injuries are more common. The goal of this article is to summarize basic guidelines for the diagnosis and treatment of vascular injuries.

Blast syndrome - pathophysiology, diagnosis and treatment of blast injuries.

The incidence of explosions in large agglomerations is high even during peacetime and continues rising. Blast syndrome injuries are complex, with shock wave causing severe injuries of multiple organ systems. In situations with large numbers of injured persons, effective triage allows an early diagnosis and treatment of the highest number of victims.

Primary Outcomes for Adults Receiving the Unified Protocol after Hurricane Harvey in an Integrated Healthcare Setting.

The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) has demonstrated efficacy for treating anxiety and depression. However, there are limited effectiveness data when conducted in real-world settings with diverse populations, including those with trauma. We evaluated treatment outcomes in a naturalistic, community setting among 279 adults who received UP following Hurricane Harvey.

Anticipating PTSD in severe COVID survivors: the case for screen-and-treat.

Based on research from previous pandemics, studies of critical care survivors, and emerging COVID-19 data, we estimate that up to 30% of survivors of severe COVID will develop PTSD. PTSD is frequently undetected across primary and secondary care settings and the psychological needs of survivors may be overshadowed by a focus on physical recovery. Delayed PTSD diagnosis is associated with poor outcomes.

Acute appendicitis during the spring COVID-19 pandemic in 2020 - a comparative retrospective study.

Introduction: Acute appendicitis (AA) is the most common abdominal emergency. This article aims to document the impact of the ongoing COVID-19 pandemic on timely diagnosis of AA, duration of symptoms before examination in a medical institution, levels of laboratory inflammatory markers, and the length of hospital stay. Collected data were compared with current world literature.

Serious negative consequences associated with exposure and response prevention for obsessive-compulsive disorder: A survey of therapist attitudes and experiences.

Objective: Many therapists are reluctant to conduct exposure and response prevention (ERP) for obsessive-compulsive disorder (OCD). Negative beliefs about the safety and tolerability of ERP are common, especially for harm-related OCD symptoms. The study examined the nature and frequency of ERP-related serious negative consequences (SNC) and therapist attitudes and experiences providing ERP for harm-related OCD.

Acute abdomen in drug abusers.

Introduction: Acute abdomen is one of the most important issues in abdominal surgery. Our study aims to describe the differences in clinical presentation of patients, in the course of their hospitalization, and in morbidity and mortality of patients with drug abuse; another aim is to describe our own experience with drug abusers with acute abdomen. Method: Patients with the history of drug abuse and with non-traumatic acute abdomen were included retrospectively to our set.

[Laparoscopic versus open left pancreatectomy: surgical stress response comparison in the porcine model].

Introduction: Although several techniques of laparoscopic left pancreatectomy have already been developed through experiments on animals and human patients, there is still insufficient information about their pathophysiological mechanisms, especially the impact on surgical stress.

Method: In a group of 10 pigs, open left pancreatectomy was performed, and the other group of 10 pigs underwent laparoscopic left pancreatectomy. Postoperative stress was compared by determining serum levels of leukocytes, interleukin 1, 6 and CRP from peripheral venous blood collection.

[Treatment of acute appendicitis: Retrospective analysis].

Introduction: Acute appendicitis is the most common cause of intra-abdominal emergency surgery worldwide. The approach to its treatment keeps changing. The number of acute appendectomies has been decreasing.

[Urgent surgical treatment of gastric volvulus related to upside-down stomach syndrome].

Upside-down stomach syndrome is a rare type of a large paraoesophageal hiatal hernia, which requires an immediate surgical treatment in case of incarceration. The authors present a case report of a 53-year-old male patient with gastric volvulus related to the upside-down stomach syndrome. Surgical treatment was complicated by an injury to distal oesophagus, which was successfully treated using a self-expandable metallic stent among other methods.

Clinical relevance and surgical anatomy of non-recurrent laryngeal nerve: 7 year experience.

Purpose: We report our clinical experience with non-recurrent inferior laryngeal nerve (NRLN).

Methods: We collected our data retrospectively during 7 years. Total thyroidectomies (TTEs; N = 626) and hemithyroidectomies (HTEs; N = 187) were performed in 766 patients (80.

An embolus in the right atrium caught in the Chiari network and resistant to thrombolysis.

This case report describes a patient with thromboemboli trapped in the Chiari network within the right side of the heart and resistant to thrombolysis. The right atrial masses were completely removed under cardiopulmonary bypass. Histological evaluation confirmed a mixed thromboemboli, with thrombus structures showing signs of organisation and surrounded by a fibrous capsule.

Zonal density gradient electrophoresis of influenza A virus.

Enzymatic activities associated with influenza A virus purified by sedimentation in sucrose density gradient were removed from the virions by sucrose density gradient electrophoresis. A rapidly migrating electrophoretic fraction contained both structural viral polypeptides and chick embryo allantoic fluid polypeptides.

Role of calcium dependent regulator protein (CDR) in inhibition of 3',5'-c AMP-phosphodiesterase by influenza virus. I. Isolation and purification of CDR and CDR-dependent 3',5'-c' AMP-phosphodiesterase from chick embryos.

Calcium-dependent regulator protein (CDR) and CDR-dependent 3',5'-c AMP-phosphodiesterase were isolated and partially purified from 12-day chick embryos. Some basic properties of the preparations obtained were described. Native (infectious) but not noninfectious (heat-inactivated) influenza virus in the presence of CDR and ATP reduced the activity of CDR-dependent phosphodiesterase.

Reactions of immune sera against the nucleocapsid, envelope and whole herpes simplex virus type 1.

Antibodies against (a) naked particles, (b) virus envelope, and (c) whole herpes simplex virus (HSV) type 1 were investigated. Immune rabbit serum against naked particles (and formalized naked particles) contained virus neutralizing (VN) antibody in a low titre as compared to the titre of complement-fixing (CF) antibody. Immune rabbit serum against the viral envelope had similar titres of VN and CF antibodies.

[Preparation of porcine IgA and its detection using the fluorescent antibody technic].

The preparation of immunoglobulin A (IgA) from porcine colostrum, intestinal content and serum is described. The best results were achieved with colostrum, from which an antigen of satisfactory purity was prepared by purification on Sephadex G-200, on DEAE cellulose and subsequent filtration on Sephadex G-200. The serum to this antigen raised in rabbits was adsorbed to an immunoadsorbent from porcine serum (PS) or porcine IgG.

Drying and irradiation of calf and horse serum. II. Influence on mycoplasma content of the calf sera.

Drying of calf sera produced only a negligible change in their content of Acholeplasma laidlawii organisms and reduced the content of Mycoplasma arginini organisms by 2 to 4 logs. Gamma-irradiation of liquid and dried calf sera killed M. arginini and A.

Drying and irradiation of calf and horse serum. I. Influence on the growth of cell cultures and mycoplasmas.

Gamma-irradiation of liquid and dried calf sera with 2.5 Mrads did not affect their capacity to promote the growth of chick embryo, L cell and human embryonic lung cell cultures. Drying and gamma-irradiation of horsesera did not affect their capacity to support the growth of 3 mycoplasma of the species Acholeplasma laidawii and Mycoplasma bovigenitalium.
