Article Synopsis
  • The introduction highlights the importance of the operating room (OR) in hospitals for patient treatment, noting that the COVID-19 pandemic led to significant operational restrictions that could have long-term negative effects on OR performance.
  • The methods involved a detailed analysis of perioperative processing times at the University Hospital Ulm, comparing data from the second quarters of 2019 to 2022, and included statistical testing to validate the findings.
  • Results showed a 31% decrease in surgeries in 2020 and persistent delays in key OR processes beyond 2020, indicating lingering impacts of the pandemic on surgical efficiency, with average operation times and anaesthesia durations remaining elevated.

Personalized health care can be optimized by including patient-reported outcomes. Standardized and disease-specific questionnaires have been developed and are routinely used. These patient-reported outcome questionnaires can be simple paper forms given to the patient to fill out with a pen or embedded in digital devices.

Due to several peculiarities the clinical treatment after terror-related mass casualty incidents (TerrorMASCAL) differs from handling a conventional MCI. For this reason, TerrorMASCAL situations should get attention as an own entity in hospitals emergency preparedness and response. Among other challenges hospitals surrounding the emergency area will have to deal with a large amount of non-triaged, non-treated and seriously harmed patients, some of them with unfamiliar and disfiguring injuries.

In its most trending interpretation, empowerment in health care is implemented as a patient-centered approach. In the same sense, many mobile health (mHealth) apps are being developed with a primary focus on the individual user. The integration of mHealth apps into the health care system has the potential to counteract existing challenges, including incomplete or nonstandardized medical data and lack of communication, especially in the intersectional context (eg, patients, medical forces).

Background: Overcoming the COVID-19 crisis requires new ideas and strategies for online communication of personal medical information and patient empowerment. Rapid testing of a large number of subjects is essential for monitoring and delaying the spread of SARS-CoV-2 in order to mitigate the pandemic's consequences. People who do not know that they are infected may not stay in quarantine and, thus, risk infecting others.

The COVID-19 pandemic has caused strains on health systems worldwide disrupting routine hospital services for all non-COVID patients. Within this retrospective study, we analyzed inpatient hospital admissions across 18 German university hospitals during the 2020 lockdown period compared to 2018. Patients admitted to hospital between January 1 and May 31, 2020 and the corresponding periods in 2018 and 2019 were included in this study.

Background: From July 2010-April 2013, Leipzig University Hospital experienced the largest outbreak of a Klebsiella pneumoniae carbapenemase 2 (KPC-2)-producing Klebsiella pneumoniae (KPC-2-Kp) strain observed in Germany to date. After termination of the outbreak, we aimed to reconstruct transmission pathways by phylogenetics based on whole-genome sequencing (WGS).

Methods: One hundred seventeen KPC-2-Kp isolates from 89 outbreak patients, 5 environmental KPC-2-Kp isolates, and 24 K pneumoniae strains not linked to the outbreak underwent WGS.

Article Synopsis
  • A study called MEDUSA looked at whether giving antibiotics quickly to sepsis patients helps them survive better.
  • They tested two groups: one group got special training to give care faster, while the other group received regular education.
  • The study found that even though giving care faster seemed helpful, it didn't actually improve survival rates, and waiting longer for antibiotics was linked to a higher chance of death.

Pulmonary arterial hypertension is a life-threatening disease with a poor prognosis. Oral treatment with vasodilators is often limited by systemic hypotension. Inhalation of vasodilators offers the opportunity for selective pulmonary vasodilation.

Background: The laryngeal tube suction II (LTS II) is a supraglottic airway device (SAD) with a gastric drainage tube and enhanced seal properties as compared with other SADs. Therefore, its use has been proposed in situations with an elevated risk of aspiration.

Objectives: To compare the safety and efficacy of airway management and controlled mechanical ventilation when using either an LTS II or an endotracheal tube for laparoscopic radical prostatectomy.

Importance: High-dose intravenous administration of sodium selenite has been proposed to improve outcome in sepsis by attenuating oxidative stress. Procalcitonin-guided antimicrobial therapy may hasten the diagnosis of sepsis, but effect on outcome is unclear.

Objective: To determine whether high-dose intravenous sodium selenite treatment and procalcitonin-guided anti-infectious therapy in patients with severe sepsis affect mortality.

Aim: To analyze differences in patients' clinical course, we compared two regimes of either preemptive therapy or prophylaxis after liver transplantation.

Methods: This retrospective study was reviewed and approved by the institutional review board of the University of Leipzig. Cytomegalovirus (CMV) prophylaxis with valganciclovir hydrochloride for liver transplant recipients was replaced by a preemptive strategy in October 2009.

Background: Inhaled carbon monoxide (CO) appears to have beneficial effects on endotoxemia-induced impairment of hypoxic pulmonary vasoconstriction (HPV). This study aims to specify correct timing of CO application, it's biochemical mechanisms and effects on inflammatory reactions.

Methods: Mice (C57BL/6; n = 86) received lipopolysaccharide (LPS, 30 mg/kg) intraperitoneally and subsequently breathed 50 ppm CO continuously during defined intervals of 3, 6, 12 or 18 h.

The use of mechanically circulatory support devices (MCS) will become increasingly important as a therapy option in patients with end-stage heart failure, and emergency physicians will more frequently encounter MCS patients in the next few years. However, emergency management in MCS patients has not yet been standardized. In the following article, common MCS devices are presented and typical emergencies associated with MCS devices are discussed.

Background: Scoring models are widely established in the intensive care unit (ICU). However, the importance in patients with ruptured abdominal aortic aneurysm (RAAA) remains unclear. Our aim was to analyze scoring systems as predictors of survival in patients undergoing open surgical repair (OSR) for RAAA.

Recommendations concerning the management of hemoglobin levels and hematocrit in patients on extracorporeal membrane oxygenation (ECMO) still advise maintenance of a normal hematocrit. In contrast, current transfusion guidelines for critically ill patients support restrictive transfusion practice. We report on a series of patients receiving venovenous ECMO (vvECMO) for acute respiratory distress syndrome (ARDS) treated according to the restrictive transfusion regimen recommended for critically ill patients.

The aim of the present study was to characterize a murine model of acute respiratory distress syndrome (ARDS) abiding by the Berlin definition of human ARDS and guidelines for animal models of ARDS. To this end, C57BL/6NCrl mice were challenged with lipopolysaccharide (LPS; 15 mg/kg, i.p.

Importance: Enteral administration of immune-modulating nutrients (eg, glutamine, omega-3 fatty acids, selenium, and antioxidants) has been suggested to reduce infections and improve recovery from critical illness. However, controversy exists on the use of immune-modulating enteral nutrition, reflected by lack of consensus in guidelines.

Objective: To determine whether high-protein enteral nutrition enriched with immune-modulating nutrients (IMHP) reduces the incidence of infections compared with standard high-protein enteral nutrition (HP) in mechanically ventilated critically ill patients.

Context: Sleep deprivation is a common problem on intensive care units (ICUs) influencing not only cognition, but also cellular functions. An appropriate sleep-wake cycle should therefore be maintained to improve patients' outcome. Multiple disruptive factors on ICUs necessitate the administration of sedating and sleep-promoting drugs for patients who are not analgo-sedated.
