Abstract
Due to the exponential growth of the number of subjects affected by coronavirus disease 2019 (COVID-19), the entire Italian health care system had to respond promptly and in a very short time with the need of semi-intensive and intensive care units. Moreover, trained dedicated COVID-19 teams consisting of physicians were coming from different specialties (intensivists or pneumologists and infectiologists), while respiratory therapists and nurses have been recruited to work on and on without rest. However, due to still limited and evolving knowledge of COVID-19, there are few recommendations concerning the need in respiratory rehabilitation and physiotherapy interventions. The presentation of this paper is the result of a consensus promoted by the Italian societies of respiratory health care professionals who contacted pulmonologists directly involved in the treatment and rehabilitation of COVID-19. The aim was to formulate the more proper and common suggestions to be applied in different hospital settings in offering rehabilitative programs and physiotherapy workforce planning for COVID-19 patients. Two main areas of intervention were identified: organization and treatment, which are described in this paper to face the emergency.

Abstract
Intensive care unit (ICU) patient, and family member engagement is evolving in both critical care medicine practice and research. The results of two qualitative critical care research projects led by ICU survivors and family members show how patient-partner research training can inform the critical care community of meaningful priorities in the traumatic ICU context. The resulting creation of a prioritized list of critical care research topics builds further on the construct of patient-centered care.

Abstract
PURPOSE There have been no large-scale studies on whether metformin therapy might have a potential benefit for lowering mortality. Thus, this study aimed to investigate the association between prior metformin therapy and the development of sepsis as well as the association between prior metformin therapy and 30-day mortality in sepsis patients. METHODS We evaluated adult diabetes patients registered in the 2010 sample cohort database of the National Health Insurance Service in South Korea. Diabetes was identified according to the International Classification of Disease-10 diagnostic system (E10-E14). The cohorts were divided into the metformin user group (i.e., those who had been prescribed continuous oral metformin over a period of ≥ 90 days) and the control group (i.e., all other individuals). The primary endpoint was the development of sepsis between 2011 and 2015, and the secondary endpoint was 30-day mortality among diabetes patients diagnosed with sepsis. RESULTS In total, 77,337 patients (34,041 in the metformin user group and 43,296 in the control group) were included in the analysis, among whom 2512 patients (3.2%) were diagnosed with sepsis between 2011 and 2015. After propensity score adjustment, metformin use was not significantly associated with both the risk of sepsis (OR: 0.92, 95%CI 0.82-1.03; P = 0.143) and the risk of 30-day mortality after diagnosis of sepsis (OR: 0.94, 95%CI 0.75-1.17; P = 0.571). CONCLUSIONS Prior metformin therapy was not significantly associated with the risk of sepsis and 30-day mortality after diagnosis of sepsis among diabetes patients.

Abstract
Aim and objective The aim and objective of this study is to test the effect of an optimized caloric supply in the first week of intensive care unit (ICU) stay in mechanically ventilated patients on the ability to perform their activities of daily living (ADL) in the long-term. Materials and methods A prospective observational study comparing patients who achieved an adequate caloric target (≥80%) vs those whose target was inadequate (<80%). The primary outcome under study is the instrumental ADL (IADL) scale after 6 months of discharge. Results Ninety-two patients were evaluated in the ICU and 50 were alive at 6 months. Follow-up was lost for 3 patients and 47 patients were evaluated at ICU and after 6 months. Thirty-four patients reached the energetic target and 13 did not reach it. There was no significant variation in IADL. Conclusion The energy adequacy in the first week of hospitalization was achieved by most survivors; however, this conduct does not seem to have influenced the ability to perform ADL after 6 months of discharge.

Abstract
BACKGROUND Acute kidney injury (AKI) commonly occurs in intensive care units (ICUs), leading to adverse clinical outcomes and increasing costs. However, there are limited epidemiological data of AKI in the critically ill in Beijing, China. METHODS In this prospective cohort study in 30 ICUs, we screened the patients up to 10 days after ICU admission. Characteristics and outcomes were compared between AKI and non-AKI, renal replacement therapy (RRT) and non-RRT patients. Nomograms of logistic regression and Cox regression were performed to examine potential risk factors for AKI and mortality. RESULTS A total of 3107 patients were included in the final analysis. The incidence of AKI was 51.0%; stages 1 to 3 accounted for 23.1, 11.8, and 15.7%, respectively. The majority (87.6%) of patients with AKI developed AKI on the first 4 days after admission to the ICU. A total of 281 patients were treated with RRT. Continuous RRT with predilution, citrate for anticoagulation and femoral vein for vascular access was the most common RRT pattern (29.9%, 84 of 281). Patients with AKI were associated with longer ICU-LOS and higher mortality and costs (P<0.001). In patients treated with RRT, 78.6 and 28.5% of RRTs were dependent on the 7th and 28th days, respectively. The 28 day mortalities of non-AKI, AKI stages 1-3, and septic shock patients were 6.83, 15.04, 27.99, 45.18 and 36.5%, respectively. CONCLUSIONS Approximately half of our ICU patients experienced AKI. The majority of patients with AKI developed AKI during the first 4 days after admission to the ICU. Continuous RRT with predilution, citrate for anticoagulation and femoral vein for vascular access was the most common RRT pattern in our ICUs. AKI was associated with a higher mortality and costs, incomplete kidney recovery and s series of adverse outcomes.

Abstract
Transesophageal echocardiography(TEE) is valuable in intensive care unit (ICU) because its application meets the requirements of diagnosis and treatment of critically ill patients.However, the current application has not fully adapted to the specialty of critical care. TEE could be more valuablein ICU when used with a new way that under the guidance of the theory of critical care and embedded into the treatment workflow. We have expanded and improved the application of traditional TEE and integrated the concept of critical care, established the concept of transesophageal echocardiography for critical care (TEECC). Chinese Critical Ultrasound Study Group (CCUSG) organized experts in the area to form the consensus based the previous studiesand the long term practice of critical care ultrasound and TEE, aiming at clarifying the nature and characteristics of TEECC, promoting the rational and standardized clinical application and the coming researches.The consensus of Chinese experts on clinical application of TEECC (2019) were 33 in total, of whichthe main items were as follows: (1) TEECC is a significant means, which is expanded and improved from the traditional transesophageal echocardiography according to characteristics of critically ill patients and is applied in ICU based on critically clinical scenarios and requirements by the critical care physician, to promote visualized, refined and precisely management of critically ill patients.(2) TEE possesses distinctive superiority in implementation in ICU. It has characteristics of images with good quality, operations with good stability and low-dependent of operators, monitoring with continuity, and visualization with all-dimensional and detail of heart and blood vessels.(3)As a means of refined monitoring that could resulted in precise diagnosis and treatment, TEECC expands the dimension of intensive monitoring and improves the performance of critical care. (4) Indications of TEECC application include clinical etiological searching and invasive procedures guiding when it acted as a traditional role; and also refined hemodynamic monitoring based on critical care rationale and over-all management under specific critical clinical scenarios. (5) TEE and TTE assessments are complementary; they are not alternative. Integrated assessment of TTE and TEE is required under many critical clinical scenarios.(6) TEE should be a necessary configuration in ICU. (7) All-round and significant information regarding to the mechanism of acute circulatory disorders can be provided by TEECC; it is a non-substitutable means of identifying the causes of shock under some special clinical scenarios. (8) Focal extracardiac hematoma can be accurately and rapidly detected by TEE in patients with open-thoracic cardiac surgery or severe chest trauma when highly suspected pericardial tamponade.(9) The priority of pathophysiologic mechanism of septic shock can be rapidly and accurately identified by TEE; even if its pathophysiological changes are complex, including hypovolemia and/or vasospasm and/or left and right heart dysfunction. (10) Causes of hemodynamic disorders can be rapidly and qualitatively evaluated so that the orientation of treatment can be clarified by TEECC. (11) A full range of quantitative indicators for refined hemodynamic management in critically ill patients can be provided by TEECC. (12) TEECC helps to accurately assess volume status and predict fluid responsiveness.(13) TEECC is specially suitable for accurate quantitative assessment of cardiac function.(14) Mini TEE provides long-term continuous hemodynamic monitoring. (15) Standard views are easy to be acquired by TEECC, which is a premise for accurate and repeatable measurements, and a guarantee for assessment of effect and risk of therapy. (16) Compared with invasive hemodynamic monitoring, TEECC is minimally invasive, with low infection risk and high safety.(17) In patients with acute cor pulmonale (ACP) under condition of right ventricular dysfunction and low cardiac output, TEECC is a key tool for assessment. (18) TEECC should be implemented actively when suspicious of left to right shunt in critically ill patients who occurred hypotension that hard to explain the cause. (19) TEECC should be implemented actively when suspicious of right to left shunt in critically ill patients who occurred hypoxemia that hard to explain the cause. (20) TEECC is preferred in hemodynamics monitoring under prone position of ventilated patients.(21) TEECC is an imperative means to achieve over-all management of extracorporeal membrane oxygenation (ECMO) therapy, especially for all-round hemodynamic monitoring. (22) Three basic views is recommended to be used to simplify TEE assessment during cardiac arrest so that reversible causes could be identified, and resuscitation could be guided. (23) The flow related echodynamic evaluation (TEECC-FREE) workflow is preferred in refined hemodynamics monitoring and therapy. (24) Simple workflow of TEECC could be implemented in special critical clinical scenarios. (25) Application of TEECC is highly secure; however, impairments of procedure should also be alert by operators. (26) Pitfalls in application of TEE should be paid attention to by the critical care physician. (27) Timely and rationally application of TEECC is in favor of diagnosis and treatment of critically ill patients and may improve the prognosis.

Abstract
PURPOSE Evidence summary resources are popular with clinicians but it is unknown whether they can influence clinical decision making. We evaluated whether an extremely condensed and explicit evidence summary tool could influence clinical decision making. MATERIALS AND METHODS An evidence summary tool was developed using a formal mapping exercise and graphic design principles. An invitation to participate was sent to subscribers of a critical care e-mail discussion list. Participants received a study package (evidence summary tool précising prone positioning in severe ARDS; case-based scenario describing a patient with severe ARDS plus evaluation questionnaire). Influence on clinical decisions was captured regarding six competing interventions, with Belief in benefit measured before and after reading the summary tool. RESULTS Among 93 participants, 87% were male with a mean age of 49.6(SD9.3) years. Mean ICU experience was 20.0(SD9.9) years. The evidence summary tool significantly influenced clinical decision making: belief in benefit of prone positioning increased (P < .001), belief in benefit of higher PEEP decreased (P = .002) and belief in benefit in ECMO decreased (P = .07). CONCLUSIONS Using a before-after evaluation, we demonstrated an extremely condensed and explicit information format can influence clinical decision making. Evidence summary tools may be a useful adjunct to support closing evidence-practice gaps.

Abstract
Emergency and critical care medicine are fraught with ethically challenging decision making for clinicians, patients, and families. Time and resource constraints, decisional-impaired patients, and emotionally overwhelmed family members make obtaining informed consent, discussing withholding or withdrawing of life-sustaining treatments, and respecting patient values and preferences difficult. When illness or trauma is secondary to disaster, ethical considerations increase and change based on number of casualties, type of disaster, and anticipated life cycle of the crisis. This article considers the ethical issues that arise when health providers are confronted with the challenges of caring for victims of disaster.

Abstract
In the absence of evidence, therapies are often based on intuition, belief, common sense or gut feeling. Over the years, some treatment strategies may become dogmas that are eventually considered as state-of-the-art and not questioned any longer. This might be a reason why there are many examples of "strange" treatments in medical history that have been applied in the absence of evidence and later abandoned for good reasons.In this article, five dogmas relevant to critical care medicine are discussed and reviewed in the light of the available evidence. Dogma #1 relates to the treatment of oliguria with fluids, diuretics, and vasopressors. In this context, it should be considered that oliguria is a symptom rather than a disease. Thus, once hypovolaemia can be excluded as the underlying reason, there is no justification for giving fluids, which may do more harm than good in euvolaemic or hypervolaemic patients. Similarly, there is no solid evidence for forcing diuresis by administering vasopressors and loop diuretics. Dogma #2 addresses the treatment of crush syndrome patients with aggressive fluid therapy using NaCl 0.9%. In fact, this treatment may aggravate renal injury by iatrogenic metabolic acidosis and subsequent renal hypoperfusion. Dogma #3 concerns the administration of NaCl 0.9% to patients undergoing kidney transplantation. Since these patients are usually characterised by hyperkalaemia, the potassium-free solution NaCl 0.9%, containing exclusively 154 mmol/l of sodium and chloride ions each, is often considered as the fluid of choice. However, large volumes of chloride-rich solutions cause hyperchloraemic acidosis in a dose-dependent manner and induce a potassium shift to the extracellular space, thereby increasing serum potassium levels. Thus, balanced electrolyte solutions are to be preferred in this setting. Dogma #4 relates to the fact that enteral nutrition is often withheld for patients with high residual gastric volume due to the theoretical risk of gastro-oesophageal reflux, potentially resulting in aspiration pneumonitis. Despite controversial discussions, there is no clinical data supporting that residual gastric volume should be generally measured, especially not in patients without a gastro-intestinal surgery and/or motility disorders. Clinical evidence rather suggests that abandoning residual gastric volume monitoring does not increase the incidence of pneumonia, but may benefit patients by facilitating adequate enteral feeding. Finally, dogma #5 is about sedating all mechanically ventilated patients because "fighting" against the respirator may cause insufficient ventilation. This concern needs to be balanced against the unwanted consequences of sedation, such as prolonged mechanical ventilation and intensive care unit length of stay as well as increased risk of delirium. Modern concepts based on adequate analgesia and moderate to no sedation appear to be more suitable.In conclusion, dogmas are still common in clinical practice. Since science rather than fiction should govern our actions in intensive care medicine, it is important to remain critical and challenge long established concepts, especially when the underlying evidence is weak or non-existing.

Abstract
IMPORTANCE Measuring and improving performance is an essential component of any high-risk industry, including intensive care medicine. We undertook this systematic review to describe the current state of quality improvement efforts in pediatric intensive care medicine. OBJECTIVE To evaluate the quality and rigor of all published literature on quality improvement efforts in the pediatric intensive care unit in the current era. METHODS We conducted a literature search on MEDLINE, Embase, and Cochrane for studies that met two broad inclusion criteria: 1) the terms "pediatric critical care" and "quality improvement" and 2) they were completed in the past ten years. In the initial search, we also included academic and professional societies or organizations devoted to providing resources on quality improvement in intensive care medicine. We excluded studies that examined quality improvement processes exclusively for neonatal or adult patients receiving intensive care. RESULTS Forty-nine of 332 identified articles were selected for final review by two reviewers who independently rated the quality of the methodology and rigor of the evidence reported for each study. Of these, 23 studies targeted structural issues, 14 studies targeted process issues, and 12 targeted an outcome as the focus of the intensive care quality improvement effort. INTERPRETATION Our review of the published literature on quality improvement efforts in the pediatric intensive care unit in the current era found that 85% of studies were limited in methodology or analysis. Fifteen high-quality studies are reported here and serve as helpful examples of rigorous research methodology in this domain going forward.

Abstract
Perioperative management of the liver transplant recipient is a team effort that requires close collaboration between intensivist, surgeon, anesthesiologist, hepatologist, nephrologist, other specialists, and hospital staff before and after surgery. Transplant viability must be reassessed regularly and particularly with each donor organ. Regular discussions with patient and family facilitate realistic determinations of goals based on patient aspirations and clinical realities. Early attention to hemodynamics with optimal resuscitation and judicious vasopressor support, respiratory care designed to minimize iatrogenic injury, and early renal support is key. Preoperative and postoperative nutritional support and physical rehabilitation should remain a focus.

Abstract
Most medical practitioners are not specifically trained to diagnose or manage in-flight medical incidents, yet there may occur a moral obligation to do so when least expected. We felt that knowledge of the frequency of emergency versus non-serious medical incidents, in addition to the clinical spectrum of incidents most often encountered, would be of interest to medical practitioners and, in particular, critical care physicians, who happen to find themselves asked to assist with such events. To this end we collaborated with the Department of Medical Services of a major Australian airline to define the incidence, severity, and type of all in-flight medical events encountered over the course of a year's flights. We audited in-flight medical data collected over a continuous 12-month period, which covered 131,890 international and domestic flight sectors transporting more than 27 million passengers. There was an average of 296 medical events per month (3555 in total) making the per-flight incidence of a medical event approximately 1:40 (2.7%). Of these in-flight incidents, 915 (26%) were graded as emergencies, with the commonest descriptors of such incidents being either loss of consciousness (37%) or a suspected cardiovascular event (12%). Six of these 915 emergencies proved fatal. Twenty-one flights were diverted due to medical incidents (<0.016% of all flights), with 52% of these attributed to suspected cardiac events. In this series, medical in-flight events were recorded in approximately one in 40 flights, whereas medical emergencies occurred in approximately one in 150 flights.

Abstract
PURPOSE Postoperative pain after cardiac surgery, exacerbated by cough and sternal mobilization, limits clearance of bronchopulmonary secretions and may predispose to postoperative pneumonia. In this study, we tested the ability of local anesthetic continuous wound infusion to prevent pneumonia after cardiac surgery with sternotomy and cardiopulmonary bypass (CPB) owing to better analgesia and bronchopulmonary drainage. METHODS In this randomized, double-blind, placebo-controlled trial conducted in five academic centers, patients undergoing cardiac surgery with sternotomy and CPB were enrolled from February 2012 until November 2014, and were followed over 30 days. Patients were assigned to a 48-h infusion (10 ml h-1) of L-bupivacaine (12.5 mg h-1) or placebo (saline) via a pre-sternal multiperforated catheter. Anesthesia and analgesia protocols were standardized. The primary end point was the incidence of pneumonia during the study period, i.e., until hospital discharge or 30 days. We hypothesized a 30% reduction in the incidence of pneumonia. RESULTS Among 1493 randomized patients, 1439 completed the trial. Pneumonia occurred in 36/746 patients (4.9%) in the L-bupivacaine group and in 42/739 patients (5.7%) in the placebo group (absolute risk difference taking into account center and baseline risk of postoperative pneumonia, - 1.3% [95% CI - 3.4; 0.8] P = 0.22). In the predefined subgroup of patients at high risk, L-bupivacaine decreased the incidence of pneumonia (absolute risk difference, - 5.6% [95% CI - 10.0; - 1.1], P = 0.01). CONCLUSIONS After cardiac surgery with sternotomy, continuous wound infusion of L-bupivacaine failed to decrease the incidence of pneumonia. These findings do not support the use of local anesthetic continuous wound infusion in this indication. Further study should investigate its effect in high-risk patients. TRIAL REGISTRATION EudraCT Number: 2011-003292-10; Clinicaltrials.gov Identifier: NCT01648777.

Abstract
Health care workers often talk about 'karma' regarding how busy a clinical service will be when a certain physician is on service. While often lighthearted, this construction of karma might have some undesirable implications by shifting our focus from our patients to ourselves.

Abstract
Analgesia and sedation play important roles in the overall treatment of critically burned adult patients. According to clinical actual situation of critically burned adult patients, a set of analgesic and sedative practices, including analgesia-based sedation, scientifically reasonable sedation status monitoring, early goal-directed sedation strategy, standardized and individualized strategy for analgesia and sedation, and early comfort using analgesia, minimal sedative, maximal human care strategy are recommended and widely implemented nowadays. However, guideline or consensus about how to provide analgesia and sedation treatment for critically burned adult patients is lacking. In this article, we discuss strategy for analgesic and sedative management in critically burned adult patients, with preexisting ideas in critical care medicine, pathophysiological characteristics of critically burned patients, and our clinical practice for reference.

Abstract
Critical care physicians may hear a surrogate decision-maker ask, "What would you do if she was your mother?" or "What if your father was this sick?" These kinds of questions ask more of the critical care physician than the surrogate might realize. There are deep-seated ethical, professional, and personal complexities that can challenge critical care physicians to answer these questions with honesty. This essay offers practical guidance for critical care physicians who aim to respond to such queries with honesty and beneficence. We discuss a variety of motivations that can accompany this unique kind of question from a surrogate. The surrogate may be seeking moral guidance-the true question being, "What should I do?" We offer a number of questions that the critical care physician might ask of the surrogate in order to attend to both the surrogate's moral dilemma and the patient's values and preferences for medical interventions. We also offer a number of questions to promote contemplation of these issues by the critical care physician herself. We argue that until the critical care physician: discovers the surrogate's motivation, connects this motivation to patient preferences, and asks herself important questions regarding death and dying, the physician's responses will not adequately attend to the issues prompted by such questions.

Abstract
Ascorbic acid (vitamin C) elicits pleiotropic effects in the body. Among its functions, it serves as a potent anti-oxidant, a co-factor in collagen and catecholamine synthesis, and a modulator of immune cell biology. Furthermore, an increasing body of evidence suggests that high-dose vitamin C administration improves hemodynamics, end-organ function, and may improve survival in critically ill patients. This article reviews studies that evaluate vitamin C in pre-clinical models and clinical trials with respect to its therapeutic potential.

Abstract
Acute liver failure (ALF) is a rare condition with fatal outcome. Characteristic is rapid onset of liver damage without preexisting liver diseases, including hepatic encephalopathy and coagulopathy. Early and correct diagnosis is essential for further management of patients, since diagnosis impacts therapy choice. Survival of patients with ALF has improved dramatically due to advances in critical care medicine and the use of liver transplantation.

Abstract
This systematic review is aimed at answering two questions: (i) Is erythrocyte aggregation a useful biomarker in assessing systemic inflammation? (ii) Does quantitative ultrasound imaging provide the non-invasive option to measure erythrocyte aggregation in real time? The search was executed through bibliographic electronic databases CINAHL, EMB Review, EMBASE, MEDLINE, PubMed and the grey literature. The majority of studies correlated elevated erythrocyte aggregation with inflammatory blood markers for several pathologic states. Some studies used "erythrocyte aggregation" as an established marker of systemic inflammation. There were limited but promising articles regarding the use of quantitative ultrasound spectroscopy to monitor erythrocyte aggregation. Similarly, there were limited studies that used other ultrasound techniques to measure systemic inflammation. The quantitative measurement of erythrocyte aggregation has the potential to be a routine clinical marker of inflammation as it can reflect the cumulative inflammatory dynamics in vivo, is relatively simple to measure, is cost-effective and has a rapid turnaround time. Technologies like quantitative ultrasound spectroscopy that can measure erythrocyte aggregation non-invasively and in real time may offer the advantage of continuous monitoring of the inflammation state and, thus, may help in rapid decision making in a critical care setup.

Abstract
The treatment of critically burned patients has benefited from the development of knowledge and technologies that we got in critical care medicine of our country in the past ten years. The close-ended management model of general intensive care unit (ICU) and the idea of general ICU doctors who treat the monitoring of organ function and alternative therapy of organs as their primary tasks would affect the treatments for special critical patients hospitalized in general ICU, especially for those patients who were severely burned. If the burn wounds of patients are not treated timely, properly or in effective manner, the final treatment outcome would be affected. Therefore, the establishment of burn ICU is necessary. The development and close-ended management of burn specialty ICU has significantly improved the success rates, reduced complications, shortened hospitalization time, and increased the quality of wound healing of severe burn patients in the past more than 10 years in our unit. With the reducing of burn, especially severe burn accidents, the construction of regional burn center and burn specialty ICU locating in burn center is necessary. It can not only reduce the waste of medical resource, but also ensure timely and professional treatments for the patients in sudden fire accidents. At present, there is no consensus on the establishment and management model of burn specialty ICU, and further discussion is needed in practice.

Abstract
With the improvement of diagnosis and treatment, tumor has become a chronic disease, and an increasing number of older patients will live with tumors. This change has led to an increase in demand for intensive care unit (ICU) and a challenge to the traditional ICU treatment concept. The option of ICU consists of two parts. The first is the option for admission. Since classic predictors of mortality are no longer relevant, we suggest broadening the criteria for ICU admission. Patients during the first course of cancer therapies should be treated with a full-code status similar to that of other patients without malignancy. Patients whose clinical response to therapy was not available or undetermined should be allowed an ICU trial that consists of unlimited invasive support, including anti-cancer therapies such as ambulatory chemotherapy. Do everything that can be done to save the patients who might benefit from ICU treatment. The second is the option of therapeutic end point. An interdisciplinary meeting, including an ethics consultation, should be held after 3-6 days'ICU trial to make end-of-life decisions with relatives of patients if the SOFA score shows clinical deterioration with no available therapeutic options. The treatment goals should shift from curative or supportive therapies to end-of-life care. we could integrate hospice and palliative care with intensive care more effectively and efficiently. That would be the future of oncological ICUs.

Epidemiology, causes, evolution and outcome in a single-center cohort of 1116 critically ill patients with hypoxic hepatitis. Ann Intensive Care 2018; 8:15. [PMID: 29383510 PMCID: PMC5790763 DOI: 10.1186/s13613-018-0356-z] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2017] [Accepted: 01/01/2018] [Indexed: 12/26/2022] Open
Abstract
Background Hypoxic hepatitis (HH) is a type of acute hepatic injury that is histologically characterized by centrilobular liver cell necrosis and that is caused by insufficient oxygen delivery to the hepatocytes. Typical for HH is the sudden and significant increase of aspartate aminotransferase (AST) in response to cardiac, circulatory or respiratory failure. The aim of this study is to investigate its epidemiology, causes, evolution and outcome. Methods The screened population consisted of all adults admitted to the intensive care unit (ICU) at the Ghent University Hospital between January 1, 2007 and September 21, 2015. HH was defined as peak AST > 5 times the upper limit of normal (ULN) after exclusion of other causes of liver injury. Thirty-five variables were retrospectively collected and used in descriptive analysis, time series plots and Kaplan–Meier survival curves with multi-group log-rank tests. Results HH was observed in 4.0% of the ICU admissions at our center. The study cohort comprised 1116 patients. Causes of HH were cardiac failure (49.1%), septic shock (29.8%), hypovolemic shock (9.4%), acute respiratory failure (6.4%), acute on chronic respiratory failure (3.3%), pulmonary embolism (1.4%) and hyperthermia (0.5%). The 28-day mortality associated with HH was 45.0%. Mortality rates differed significantly (P = 0.007) among the causes, ranging from 33.3% in the hyperthermia subgroup to 52.9 and 56.2% in the septic shock and pulmonary embolism subgroups, respectively. The magnitude of AST increase was also significantly correlated (P < 0.001) with mortality: 33.2, 44.4 and 55.4% for peak AST 5–10× ULN, 10–20× ULN and > 20× ULN, respectively. Conclusion This study surpasses by far the largest cohort of critically ill patients with HH. HH is more common than previously thought with an ICU incidence of 4.0%, and it is associated with a high all-cause mortality of 45.0% at 28 days. The main causes of HH are cardiac failure and septic shock, which include more than 3/4 of all episodes. Clinicians should search actively for any underlying hemodynamic or respiratory instability even in patients with moderately increased AST levels.

Abstract
STUDY OBJECTIVES Point-of-care ultrasound (POCUS) has been a rapidly growing and broadly used modality in recent decades. The purpose of this study was to determine how POCUS is incorporated into clinical medicine by analyzing trends of use in the published literature. METHODS POCUS-related publications were retrieved from the Web of Science (WoS) database. The search results were ranked according to the number of times an article was cited during three time frames and average annual number of citations. Of the top 100 most cited publications in the four rankings, information regarding the publication journal, publication year, first author's nationality, field of POCUS application, and number of times the article was cited was recorded for trend analysis. RESULTS A total of 7860 POCUS-related publications were retrieved, and publications related to POCUS increased from 8 in 1990 to 754 in 2016. The top 148 cited publications from the four ranking groups were included in this study. Trauma was the leading application field in which POCUS was studied prior to 2001. After 2004, thorax, cardiovascular, and procedure-guidance were the leading fields in POCUS research. >79% (118/148) of the top-cited publications were conducted by authors in the United States, Italy, and France. The majority of publications were published in critical care medicine and emergency medicine journals. CONCLUSIONS In recent years, publications relating to POCUS have increased. POCUS-related research has mainly been performed in thorax, cardiovascular, and procedure-guidance ultrasonography fields, replacing trauma as the major field in which POCUS was previously studied.
