Cumulative oxygen deficit is a novel predictor for the timing of invasive mechanical ventilation in COVID-19 patients with respiratory distress.

Background And Objectives: The timing of invasive mechanical ventilation (IMV) is controversial in COVID-19 patients with acute respiratory hypoxemia. The study aimed to develop a novel predictor called cumulative oxygen deficit (COD) for the risk stratification.

Methods: The study was conducted in four designated hospitals for treating COVID-19 patients in Jingmen, Wuhan, from January to March 2020.

Shp2 positively regulates cigarette smoke-induced epithelial mesenchymal transition by mediating MMP-9 production.

Cigarette smoke (CS) is a major risk factor for the development of lung cancer and chronic obstructive pulmonary disease (COPD). Epithelial-mesenchymal transition (EMT) commonly coexists in lung cancer and COPD. CS triggers many factors including matrix metalloproteinases (MMPs) production, contributing to EMT progression in the lungs.

A rapid response team is associated with reduced overall hospital mortality in a Chinese tertiary hospital: a 9-year cohort study.

Background: Although the evidence for its effectiveness remains uncertainty, rapid response systems are implemented across many hospitals across the world. Increasingly, hospitals in China have recently started to adopt a medical emergency or rapid response team (RRT). Hence, we aimed to determine whether the implementation of an RRT in Chinese hospitals also improved outcomes.

Utilization of echocardiography during septic shock was associated with a decreased 28-day mortality: a propensity score-matched analysis of the MIMIC-III database.

Background: Hemodynamic management is of paramount importance in patients with septic shock. Echocardiography has been increasingly used in assessing volume status and cardiac function. However, whether the utilization of echocardiography has an impact on prognosis is unknown.

Factors associated with outcomes of septic shock patients receiving high dose noradrenaline according to three primary infection sites.

Objective: To identify factors associated with outcome of septic shock patients receiving high dose noradrenaline according to three primary infection sites.

Methods: This retrospective study was based on data from a publicly available ICU database (Medical Information Mart for Intensive Care [MIMIC] III. Septic shock patients receiving high dose (≥1 μg/kg per min) noradrenaline and ≥18 years were identified and their characteristics and outcomes were compared according to three primary infection sites (abdominal, respiratory and urinary tract).

High 28-day mortality in critically ill patients with sepsis and concomitant active cancer.

Objective: This study was performed to explore the characteristics and outcomes of patients with sepsis accompanied by active cancer who were admitted to the intensive care unit (ICU).

Methods: The baseline characteristics, infection profiles, and outcomes of patients with sepsis were retrospectively analyzed according to the presence of concomitant active cancer. The association between concomitant active cancer and 28-day mortality was explored.

High Serum Iron level is Associated with Increased Mortality in Patients with Sepsis.

Iron is an essential nutrient for bacterial survival and thus higher iron levels may precipitate bacterial infections. We investigated the association between the serum iron level and prognosis in patients with sepsis by using the single-centre Medical Information Mart for Intensive Care III (MIMIC-III) database. Sepsis patients with iron parameters measured on ICU admission were included and stratified according to quartiles of serum iron levels.

Comparison of the predictive value of scoring systems on the prognosis of cirrhotic patients with suspected infection.

Cirrhotic patients with infection are prone to develop sepsis or even septic shock rendering poorer prognosis. However, few methods are available to predict the prognosis of cirrhotic patients with infection although there are some scoring systems can be used to predict general patients with cirrhosis. Therefore, we aimed to explore the predictive value of scoring systems in determining the outcome of critically ill cirrhotic patients with suspected infection.

Two-tube method for treatment of spontaneous esophageal rupture and concomitant mediastinal infection.

Objective Spontaneous esophageal rupture (SER) is a rare but life-threatening condition with high mortality. The prognosis of patients with SER treated with surgical intervention or the traditional "three-tube" method is controversial. Thus, the aim of this study was to evaluate the clinical efficacy, feasibility, and safety of a new "two-tube" method involving a trans-fistula drainage tube and a three-lumen jejunal feeding tube for the treatment of SER without concomitant pleural rupture.

Intensive blood pressure control in patients with acute type B aortic dissection (RAID): study protocol for randomized controlled trial.

Background: Blood pressure control is an essential therapy for patients with acute type B aortic dissection (ABAD) and should be maintained throughout the entire treatment. Thus, vast majority current guidelines recommend control the blood pressure to lower than 140/90 mmHg. Theoretically, a much lower target may further decrease the risk of propagation of dissection.

Attitudes toward the American nutrition guidelines for the critically ill patients of Chinese intensive care physicians.

Nutrition therapy is essential for the management of critically ill patients. Some guidelines have been published to standardize and optimize the nutrition therapy. However, there are still many controversies in nutrition practice and there is a gap between guidelines and clinical nutrition therapy for patients in intensive care units (ICUs).

Clinical and microbiological characteristics of Klebsiella pneumoniae liver abscess in East China.

Background: Klebsiella pneumoniae has been the dominant pathogen for liver abscesses in several Asian countries. Although the prevalence of K. pneumoniae liver abscess (KLA) in mainland China is increasing recently, the clinical and microbiological characteristics of KLA in China have not been elucidated.

Good neurological recovery after rescue thrombolysis of presumed pulmonary embolism despite prior 100 minutes CPR.

We reported the case of a 70-year-old man who was admitted to neurologic wards for recurrent syncope for 3 years. Unfortunately, just 2 hours after his admission, he suddenly collapsed and failed to return of spontaneous circulation (ROSC) after a 100-minute standard cardiopulmonary resuscitation (CPR). Fortunately, he was timely suspected to have pulmonary embolism (PE) based on his sedentary lifestyle, elevated D-dimer and markedly enlarged right ventricle chamber on bedside echocardiography.

Antihypertensive therapy with nicardipine for patients with aortic disease is associated with more esmolol usage than urapidil.

Background: Acute aortic disease is a common but challenging entity in clinical practice. Titration the blood pressure and heart rate to a target level is of paramount importance in the acute phase regardless of whether the patient will undergo a surgery or not eventually. In addition to the initially intravenous β-blockers, parenteral infusion of nicardipine and urapidil are the most common used antihypertensive therapy currently in mainland China.

Delayed admission to ICU does not increase the mortality of patients post neurosurgery.

Increasing shortage of intensive care resources is a worldwide problem. While routine postoperative admission to the intensive care unit (ICU) of patients undergoing neurosurgery is a long established practice for many hospitals. Therefore, some neurosurgical patients have to be cared in post anesthesia care unit (PACU) before ICU admission during high ICU occupancy.

The carina is approximately 1-2 cm above the pericardial reflection among Chinese patients.

Background: Central venous catheters (CVCs) and central venous pressure (CVP) monitor is essential in fluid resuscitation and management for critically ill patients. Accuracy of the CVP is mainly dependent on the proper position of the catheter tip. Although the X-ray visible carina was generally recommended as the alternative of pericardial reflection (PR) to guide the placement of CVCs, few data was available with respect to the distance between the carina and PR among Chinese patients.

Awareness and use of the Canadian computed tomography head rule for mild head injury patients among Chinese emergency physicians.

Objective: Computed tomography (CT) scan has been an increasingly essential diagnostic tool for emergency physicians (EPs) to triage emergency patients. Canadian computed tomography Head Rule (CCHR) had been established and widely used to spare patients with mild head injury from unnecessary radiation. However, the awareness of CCHR and its actual utilization among Chinese EPs were unknown.

Trends in computed tomography utilization and association with hospital outcomes in a Chinese emergency department.

Background: Excessive use of computed tomography (CT) in emergency departments (EDs) has become a concern due to its expense and the potential risks associated with radiation exposure. Although studies have shown a steady increase in the number of CT scans requested by ED physicians in developed countries like the United States and Australia, few empirical data are available regarding China.

Methods And Findings: We retrospectively analyzed a database of ED visits to a tertiary Chinese hospital to examine trends in CT utilization and their association with ED outcomes between 2005 and 2008.

High hospital occupancy is associated with increased risk for patients boarding in the emergency department.

Background: Boarding admitted patients in the emergency department due to high hospital occupancy is a worldwide problem. However, whether or not emergency department-boarded patients managed by emergency department providers subjects them to increased serious complications needs further clarification.

Methods: A multivariate logistic regression analysis was used to examine the relationship of patient's age, sex, arrival hours, diagnostic category, triage category, daily emergency department visits, and daily hospital occupancy to the occurrence of serious complications within 24 hours for 20,276 emergency admissions in a 4-year period.

Current recognition and management of intra-abdominal hypertension and abdominal compartment syndrome among tertiary Chinese intensive care physicians.

This survey was designed to clarify the current understanding and clinical management of intra-abdominal hypertension (IAH)/abdominal compartment syndrome (ACS) among intensive care physicians in tertiary Chinese hospitals. A postal twenty-question questionnaire was sent to 141 physicians in different intensive care units (ICUs). A total of 108 (76.

Effect of increased intra-abdominal pressure and decompressive laparotomy on aerated lung volume distribution.

Increased intra-abdominal pressure (IAP) is common in intensive care patients, affecting aerated lung volume distribution. The current study deals with the effect of increased IAP and decompressive laparotomy on aerated lung volume distribution. The serial whole-lung computed tomography scans of 16 patients with increased IAP were retrospectively analyzed between July 2006 and July 2008 and compared to controls.
