Moral Distress in Clinicians Caring for Critically Ill Patients Who Require Mechanical Circulatory Support

Although use of mechanical circulatory support is increasing, it is unclear how providing such care affects clinicians' moral distress. To measure moral distress among intensive care unit clinicians who commonly care for patients receiving mechanical circulatory support. In this prospective study, the Moral Distress Scale-Revised was administered to physicians, nurses, and advanced practice providers from 2 intensive care units in an academic medical center. Linear regression was used to assess whether moral distress was associated with clinician type, burnout, or desire to leave one's job. Clinicians' likelihood of reporting frequent moral distress when caring for patients receiving mechanical circulatory support vs other critically ill patients also was assessed. The sample comprised 102 clinicians who had a mean (SD) score of 100.5 (51.6) on the Moral Distress Scale- Revised. After adjustment for clinician characteristics, moral distress was significantly higher in registered nurses than physicians/advanced practice providers (115.9 vs 71.0, P < .001), clinicians reporting burnout vs those who did not (114.7 vs 83.1, P = .003), and those considering leaving vs those who were not (121.1 vs 89.2, P = .001). Clinicians were more likely to report experiencing frequent moral distress when caring for patients receiving mechanical circulatory support (26.5%) than when caring for patients needing routine care (10.8%; P = .004), but less likely than when caring for patients with either chronic critical illness (57.8%) or multisystem organ failure (56.9%; both P < .001). Moral distress was high among clinicians who commonly care for patients receiving mechanical circulatory support, suggesting that use of this therapy may affect well-being among intensive care unit clinicians.

Days out of Institution after Tracheostomy and Gastrostomy Placement in Critically Ill Older Adults.

Rationale: Tracheostomy and gastrostomy tubes are frequently placed during critical illness for long-term life support, with most placed in older adults. Large knowledge gaps exist regarding outcomes expressed as most important to patients. Objectives: To determine the number of days alive and out of institution (DAOIs) and mortality after tracheostomy and gastrostomy placement during critical illness and to evaluate associations between health states before critical illness and outcomes. Methods: In this retrospective cohort study of Medicare beneficiaries admitted to an intensive care unit (ICU) who received a tracheostomy, gastrostomy, or both, we determined the number of DAOIs after procedure date; 90-day, 6-month, and 1-year mortality; hospital discharge destination; and hospital length of stay. We used claims from the year before admission to define eight mutually exclusive pre-ICU health states (permutations of one or more of cancer, chronic organ failure, frail, and robust) and assessed their association with DAOIs in 90 days and 1-year mortality. Results: Among 3,365 patients who received a tracheostomy, 6,709 patients who received a gastrostomy tube, and 3,540 patients who received both procedures, the median number of DAOIs in the first 90 days after placement was 3 (interquartile range, 0-46), 12 (0-61), and 0 (0-37), respectively. Over half died within 180 days. One-year mortality was 62%, 60%, and 64%, respectively. When compared with the robust state, all other pre-ICU health states were associated with loss of DAOIs and increased 1-year mortality; however, between the seven non-robust pre-ICU health states, there were no differences in outcomes. Conclusions: Medicare beneficiaries with prior comorbidity who received tracheostomy, gastrostomy tube, or both during critical illness spent few DAOIs and had high short- and long-term mortality.

Nutritional status and determinants of malnutrition in institutionalized elderly people, provisional data

Nutrition is an important factor for health, physical and cognitive function, vitality, quality of life and longevity. Elderly people oft en have low food intake, induced by multifactorial causes, as a result, malnutrition is an independent risk factor for increased morbidity and mortality, regardless of the underlying pathologies (chronic organ failure, cognitive impairment, cancer, cardiovascular disease, type 2 diabetes etc.) including overweight or obese subjects.The prevalence of malnutrition varies from 4% to 10% in the elderly population from the community, from 15% to 38% for institutionalized elderly people and from 30% to 70% for hospitalized ones. The purpose of this study was to assess the nutritional status of institutionalized elderly people and establish correlations between the determinants of malnutrition and fragility syndrome.Th e epidemiological study is part of the project 20.80009.8007.25 “Fragility: diagnosis and prophylaxis in relation to medicopsychosocial problems of the vulnerable elderly”, included 50 patients institutionalized in the Republican Asylum for the Disabled and Retired in Chisinau.All persons were examined by the complex geriatric evaluation, approved by the order of the Ministry of Health no. 619 of 07.09.2010. According to the results, both malnutrition and the risk of malnutrition were high in institutionalized elderly people.Among the determinants of malnutrition, the highest association had the number of concomitant diseases, decreased functionality of the elderly, the presence of depression syndrome and cognitive disorders. At the same time, the malnutrition syndrome correlated with the fragility criteria but also with the degree of severity of frailty of the institutionalized elderly people.

Resveratrol prevented spatial deficits and rescued disarrayed hippocampus asymmetric dimethylarginine and brain-derived neurotrophic factor levels in young rats with increased circulating asymmetric dimethylarginine.

Increased plasma levels of asymmetric dimethylarginine can be encountered in chronic inflammatory disease, liver damage, renal failure, and multiple organ failure. In addition, an association between circulating asymmetric dimethylarginine levels and all-cause mortality has been reported. Male Sprague-Dawley rats, postnatal day 17 ± 1, received continuous asymmetric dimethylarginine infusion via an intraperitoneal pump. Spatial performance and dorsal hippocampal asymmetric dimethylarginine and brain-derived neurotrophic factor (BDNF) levels were examined, and the effect of resveratrol was tested. A 4-week continuous asymmetric dimethylarginine infusion in young male rats caused spatial deficits, increased asymmetric dimethylarginine levels, and decreased BDNF expression in the dorsal hippocampus. Increased oxidative stress and altered molecules in the dorsal hippocampus linked to asymmetric dimethylarginine and BDNF functions were detected. Resveratrol protected against these effects, reversing spatial deficits, and reducing the changes in the dorsal hippocampal asymmetric dimethylarginine and BDNF levels.

Safety and Feasibility of a Novel Percutaneous Locoregional Injection Technique of Renal Cellular Therapy for Chronic Kidney Disease of Diabetes

Early cell and gene therapies show promise to achieve positive treatment outcomes, primarily for cancer and hereditary conditions; however, there is a lack of therapeutic options for chronic organ failure, such as chronic kidney disease (CKD).1,2 CKD represents a growing global health crisis, predicted to affect more than 250 million people with type 2 diabetes as the leading cause in greater than 40% of selected populations and the dominant cause for end-stage kidney disease.3,4

Dysregulation of the Lysophosphatidylcholine/Autotaxin/Lysophosphatidic Acid Axis in Acute-on-Chronic Liver Failure Is Associated With Mortality and Systemic Inflammation by Lysophosphatidic Acid-Dependent Monocyte Activation.

Acute-on-chronic liver failure (ACLF) is characterized by systemic inflammation, monocyte dysfunction, and susceptibility to infection. Lysophosphatidylcholines (LPCs) are immune-active lipids whose metabolic regulation and effect on monocyte function in ACLF is open for study. Three hundred forty-two subjects were recruited and characterized for blood lipid, cytokines, phospholipase (PLA), and autotaxin (ATX) concentration. Peripheral blood mononuclear cells and CD14+ monocytes were cultured with LPC, or its autotaxin (ATX)-derived product, lysophosphatidic acid (LPA), with or without lipopolysaccharide stimulation and assessed for surface marker phenotype, cytokines production, ATX and LPA-receptor expression, and phagocytosis. Hepatic ATX expression was determined by immunohistochemistry. Healthy volunteers and patients with sepsis or acute liver failure served as controls. ACLF serum was depleted in LPCs with up-regulated LPA levels. Patients who died had lower LPC levels than survivors (area under the receiver operating characteristic curve, 0.94; P<0.001). Patients with high-grade ACLF had the lowest LPC concentrations and these rose over the first 3days of admission. ATX concentrations were higher in patients with AD and ACLF and correlated with Model for End-Stage Liver Disease, Consortium on Chronic Liver Failure-Sequential Organ Failure Assessment, and LPC/LPA concentrations. Reduction in LPC correlated with higher monocyte Mer-tyrosine-kinase (MerTK) and CD163 expression. Plasma ATX concentrations rose dynamically during ACLF evolution, correlating with IL-6 and TNF-α, and were associated with increased hepatocyte ATX expression. ACLF patients had lower human leukocyte antigen-DR isotype and higher CD163/MerTK monocyte expression than controls; both CD163/MerTK expression levels were reduced in ACLF ex vivo following LPA, but not LPC, treatment. LPA induced up-regulation of proinflammatory cytokines by CD14+ cells without increasing phagocytic capacity. ATX up-regulation in ACLF promotes LPA production from LPC. LPA suppresses MerTK/CD163 expression and increases monocyte proinflammatory cytokine production. This metabolic pathway could be investigated to therapeutically reprogram monocytes in ACLF.

Effectiveness of sepsis bundle application and outcomes predictors to cirrhotic patients with septic shock

IntroductionCirrhotic patients with septic shock have a poorer prognosis compared with the general population. Our study aimed to investigate the survival benefit of the implementation of hour-1 bundle proposed by Surviving Sepsis Campaign, and to analyze the predictors associated with short-term mortality of these patients.MethodsA single-center, retrospective case-control study was conducted among adult patients who visited the emergency department between January 1, 2018 and December 31, 2019. All patients with a diagnosis of liver cirrhosis and septic shock were enrolled. Their baseline characteristics, laboratory results, source of sepsis, and sepsis bundle management were recorded. We further divided the patients into survivor and non-survivor groups to identify independent prognostic factors.ResultsA total of 88 patients were eligible for this study. The overall 30-day mortality rate was 53.4% (47/88). The proportion of hour-1 bundle achievement was 30.7% (27/88). There were no significant mortality differences between the hour-1 bundle achievement and non-achievement groups (44.4% vs. 57.4%, p = 0.35). Compared with the patients in the survivor group, patients in the non-survivor group had significantly more advanced stage of cirrhosis and a lower proportion of receiving source control (4.3% vs. 22.0%, p = 0.02). The chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score (adjusted hazard ratio [AHR] =1.52, p < 0.01), serum lactate (AHR =1.03, p < 0.01), and source control (AHR =0.54, p = 0.02) were identified as independent prognostic factors in the multivariate regression model. Furthermore, the CLIF-SOFA score (area under curve [AUC]: 0.81) and lactate levels (AUC: 0.77) revealed good mortality discrimination ability in cirrhotic patients with septic shock.ConclusionsThe application of the hour-1 bundle did not reveal a significant survival benefit to cirrhotic patients with septic shock. Clinicians could utilize CLIF-SOFA scores and lactate levels for mortality risk stratification and put more emphasis on the feasibility of source control to improve their prognosis.

Predictors and outcome of emergent Liver transplantation for patients with acute-on-chronic liver failure

Background and aimsControversy exists over whether emergent liver transplantation (LT) should be performed for patients with acute-on-chronic liver failure (ACLF), especially for patients with multiple organ failure. MethodsA total of 110 ACLF patients, defined by the European Association for the Study of the Liver (EASL) Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) criteria were analyzed. The primary outcome was overall survival after ACLF diagnosis. ResultsDuring follow-up, 76 patients received LT (59 received deceased-donor LT and 17 patients received living-donor LT). The overall survival was better for patients who received LT than patients who did not (82.9% vs. 17.6%, P < 0.001). Among the 76 patients who received LT, the overall survival was not different according to ACLF grade at diagnosis (70.0%, 85.3%, and 84.4% at one-year for ACLF grades 1, 2, and 3, respectively, P = 0.45). The baseline model for end-stage liver disease (MELD) score and progression of the ACLF grade during the pre-transplant period were independent factors for survival after LT. The one-year survival rate was 92.3% for patients with baseline MELD scores of ≤ 32 without ACLF grade progression, whereas it was 33.3% for those with baseline MELD scores of > 32 and ACLF grade progression. ConclusionsEmergent LT provided a significant survival benefit to ACLF patients, regardless of the baseline ACLF grade. Post-LT outcomes were associated with baseline MELD scores and ACLF progression during the pre-transplant period, which might be used in the emergent LT plan for patients presenting with ACLF.

A nomogram to predict survival in patients with acute-on-chronic hepatitis B liver failure after liver transplantation.

Individualized prediction of survival after liver transplantation (LT) for patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) has not been well investigated. This study aimed to develop a prognostic nomogram for patients with HBV-ACLF undergoing LT. The nomogram was derived from a retrospective study of 290 patients who underwent LT for HBV-ACLF at the Third Affiliated Hospital of Sun Yat-sen University between January 2012 and December 2017. Concordance index and determiner calibration curve was used to ascertain the predictive accuracy and discriminative ability of the nomogram. The predictive performance of the nomogram was compared with that of Child-Pugh score, model for end-stage liver disease (MELD), MELD-Na, chronic liver failure Consortium Organ Failure score (CLIF-C OFs), and CLIF-C ACLF. The 1-year mortality rate was 23.1% (67/290). The Cox multivariate analysis showed that risk factors for 1-year survival rate included white blood cell count, alanine aminotransferase/aspartate aminotransferase ratio, and the organ failure numbers. The determiner calibration curve showed good agreement between prediction of the nomogram and actual observation. The concordance index of the nomogram for predicting 1-year survival was 0.707, which was significantly higher than that of other prognostic models: Child-Pugh score (0.626), MELD (0.627), MELD-Na (0.583), CLIF-C OF (0.674), and comparable to that of CLIF-C ACLF (0.684). Our study developed a novel nomogram that could accurately predict individualized post-transplantation survival in patients with HBV-ACLF. The nomogram might be a useful tool for identifying HBV-ACLF patients who would benefit from LT.

Advanced Practice Provider-inclusive Staffing Models and Patient Outcomes in Pediatric Critical Care.

Pediatric intensive care units (PICUs) are increasingly staffed with advanced practice providers (APPs), supplementing traditional physician staffing models. We evaluate the effect of APP-inclusive staffing models on clinical outcomes and resource utilization in US PICUs. Retrospective cohort study of children admitted to PICUs in 9 states in 2016 using the Healthcare Cost and Utilization Project's State Inpatient Databases. PICU staffing models were assessed using a contemporaneous staffing survey. We used multivariate regression to examine associations between staffing models with and without APPs and outcomes. The primary outcome was in-hospital mortality. Secondary outcomes included odds of hospital acquired conditions and ICU and hospital lengths of stay. The sample included 38,788 children in 40 PICUs. Patients admitted to PICUs with APP-inclusive staffing were younger (6.1±5.9 vs. 7.1±6.2 y) and more likely to have complex chronic conditions (64% vs. 43%) and organ failure on admission (25% vs. 22%), compared with patients in PICUs with physician-only staffing. There was no difference in mortality between PICU types [adjusted odds ratio (AOR): 1.23, 95% confidence interval (CI): 0.83-1.81, P=0.30]. Patients in PICUs with APP-inclusive staffing had lower odds of central line-associated blood stream infections (AOR: 0.76, 95% CI: 0.59-0.98, P=0.03) and catheter-associated urinary tract infections (AOR: 0.73, 95% CI: 0.61-0.86, P<0.001). There were no differences in lengths of stay. Despite being younger and sicker, children admitted to PICUs with APP-inclusive staffing had no increased odds of mortality and lower odds of some hospital acquired conditions compared with those in PICUs with physician-only staffing. Further research can inform APP integration strategies which optimize outcomes.

Comparison of Palliative Care Delivery in the Last Year of Life Between Adults With Terminal Noncancer Illness or Cancer

Palliative care improves health outcomes, but studies of the differences in the delivery of palliative care to patients with different types of serious illness are lacking. To examine the delivery of palliative care among adults in their last year of life who died of terminal noncancer illness compared with those who died of cancer. This population-based cohort study used linked health administrative data of adults who received palliative care in their last year of life and died between January 1, 2010, and December 31, 2017, in Ontario, Canada. Cause of death (chronic organ failure, dementia, or cancer). Components of palliative care delivery, including timing and location of initiation, model of care, physician mix, care settings, and location of death. A total of 145 709 adults received palliative care (median age, 78 years; interquartile range, 67-86 years; 50.7% female); 21 054 died of chronic organ failure (4704 of heart failure, 5715 of chronic obstructive pulmonary disease, 3785 of end-stage kidney disease, 579 of cirrhosis, and 6271 of stroke), 14 033 died of dementia, and 110 622 died of cancer. Palliative care was initiated earlier (>90 days before death) in patients with cancer (32 010 [28.9%]) than in those with organ failure (3349 [15.9%]; absolute difference, 13.0%) or dementia (2148 [15.3%]; absolute difference, 13.6%). A lower proportion of patients with cancer had palliative care initiated in the home (16 088 [14.5%]) compared with patients with chronic organ failure (6904 [32.8%]; absolute difference, -18.3%) or dementia (3922 [27.9%]; absolute difference, -13.4%). Patients with cancer received palliative care across multiple care settings (92 107 [83.3%]) more often than patients with chronic organ failure (12 061 [57.3%]; absolute difference, 26.0%) or dementia (7553 [53.8%]; absolute difference, 29.5%). Palliative care was more often delivered to patients with cancer (80 615 [72.9%]) using a consultative or specialist instead of a generalist model compared with patients with chronic organ failure (9114 [43.3%]; absolute difference, 29.6%) or dementia (5634 [40.1%]; absolute difference, 32.8%). Patients with cancer (42 718 [38.6%]) received shared palliative care more often from general practitioners and physicians with subspecialty training, compared with patients with chronic organ failure (3599 [17.1%]; absolute difference, 21.5%) or dementia (1989 [14.2%]; absolute difference, 24.4%). In this cohort study, there were substantial patient- and practitioner-level differences in the delivery of palliative care across distinct types of serious illness. These patient- and practitioner-level differences have important implications for the organization and scaled implementation of palliative care programs, including enhancement of practitioner education and training and improvements in equitable access to care across all settings.

Acute-on-Chronic Liver Failure in Children: A Single-Center Experience.

Acute-on-chronic liver failure and its outcomes have not yet been evaluated in detail in children. We aimed to evaluate the etiology, acute events, and prognostic factors of acute-on-chronic liver failure in children. Pediatric patients (age 2-18 years) diagnosed with acute-on-chronic liver failure between April 2014 and April 2020 were evaluated retrospectively. Acute-on-chronic liver failure was defined as the presence of acute hepatic insult in previously diagnosed or undiagnosed chronic liver disease causing jaundice (total serum bilirubin ≥5 mg/dL) and coagulopathy (international normalized ratio of ≥2.0) and clinical and/or radiological ascites and/or hepatic encephalopathy within 4 weeks. Acute-on-Chronic Liver Failure Research Consortium and Chronic Liver Failure-Sequential Organ Failure Assessment scores were calculated for patients at first admission and at end of day 5 or before liver transplant. Our study included 29 patients. Underlying chronic liver diseases were mostly autoimmune hepatitis (51.72%) and Wilson disease (27.58%), with flare-ups of these diseases also the most common acute events (48.28% and 27.58%, respectively). Seven patients (24.14%) received liver transplants. At first admission, Acute-on-Chronic Liver Failure Research Consortium and Chronic Liver Failure-Sequential Organ Failure Assessment cut-off scores to predict liver transplant were 7.5 and 6.5; at end of day 5 or before transplant, cut-off scores were 8.5 and 7.5, respectively. The 8.5 cut-off score on day 5 was the most specific and sensitive to predict liver transplant. International normalized ratio cut-off of 3.04 predicted transplant requirement with maximum sensitivity and specificity. Wilson disease and autoimmune hepatitis were the most common underlying chronic and acute events of acute-on-chronic liver failure in children. Although an Acute-on-Chronic Liver Failure Research Consortium score ≥ 8.5 best predicted liver transplant, for patients with scores ≥ 7.5 and being followed in a nontransplant center, patient referral to a transplant center is appropriate.

To contrast and reverse skeletal muscle weakness by Full-Body In-Bed Gym in chronic COVID-19 pandemic syndrome

Mobility-impaired persons, either very old or younger but suffering with systemic neuromuscular disorders or chronic organ failures, spend small amounts of time for daily physical activity, contributing to aggravate their poor mobility by resting muscle atrophy. Sooner or later the limitations to their mobility enforce them to bed and to more frequent hospitalizations. We include among these patients at risk those who are negative for the SARS-COV-2 infection, but suffering with COVID-19 pandemic syndrome. Beside managements of psychological symptoms, it is mandatory to offer to the last group physical rehabilitation approaches easy to learn and self-managed at home. Inspired by the proven capability to recover skeletal muscle contractility and strength by home-based volitional exercises and functional electrical stimulation, we suggest also for chronic COVID-19 pandemic syndrome a 10-20 min long daily routine of easy and safe physical exercises that can activate, and recover from weakness, the main 400 skeletal muscles used for every-day mobility activities. Persons can do many of them in bed (Full-Body in-Bed Gym), and hospitalized patients can learn this light training before leaving the hospital. It is, indeed, an extension of well-established cardiovascular-respiratory rehabilitation training performed after heavy surgical interventions. Blood pressure readings, monitored before and after daily routine, demonstrate a transient decrease in peripheral resistance due to increased blood flow of many muscles. Continued regularly, Full-Body in-Bed Gym may help maintaining independence of frail people, including those suffering with the COVID-19 pandemic syndrome.

Initial experience with high-volume plasma exchange in patients with acute liver failure.

High-volume plasma exchange (HVPE), defined as an exchange of 8 to 12 L per day per procedure or 15% of the ideal body weight with fresh frozen plasma, has shown promising results in improving the survival of patients with acute liver failure (ALF). However, clinical evidence is limited. The aim of this study was to report our initial experience using HVPE as a bridge treatment in patients with ALF. We retrospectively reviewed 32 consecutive patients awaiting liver transplantation (LT) due to ALF between 2013 and 2020 at Samsung Medical Center in Korea. HVPE has been used for patients with ALF since May 2016 at our institution. During the study period, 16 patients received HVPE. After HVPE, coagulopathies (INR, 4.46 [2.32-6.02] vs 1.48 [1.33-1.76], P < .05), total bilirubin (22.6 [9.1-26.4] vs 8.9 [5.6-11.3], P < .05), alanine aminotransferase (506 [341-1963] vs 120 [88-315], P < .05), and ammonia levels (130.6 [123.7-143.8] vs 98.2 [84.2-116.5], P < .05) were improved. Improvement in the hepatic encephalopathy grade was observed in four patients. Among 16 patients who received HVPE, 12 patients were bridged to LT, and three patients recovered spontaneously. The overall survival was 94% and 69%, respectively at 30 days in patients who received and did not receive HVPE (P =.068). Among 18 patients with high chronic liver failure-sequential organ failure assessment scores (≥13), the overall survival was significantly better for those who received HVPE than for those who did not (91% vs 29%, respectively, at 30 days, P < .05). Our initial clinical experience with HVPE suggests that HVPE can be a viable option in improving the outcomes of patients presenting with ALF.

Who needs, receives and misses out on palliative and end-of-life care? A population-based study to identify needs and gaps in a regional health service.

Objective The aim of this study was to assess the unmet need for palliative and other end-of-life care, as well as the sociodemographic and diagnostic factors associated with suboptimal access, among residents in an Australian region. Methods A cross-sectional descriptive and analytical study was performed using non-identifiable linked data from four administrative and two clinical datasets. The study population comprised 3175 patients aged ≥15 years who died in hospital in 2016 and 2017. The main outcome measures were the proportion of decedents potentially benefitting from end-of-life care and receiving end-of-life care. Results An estimated 74.8% of decedents needed palliative or other end-of-life care in the year before death. Approximately 13.3% did not receive any end-of-life care despite its potential benefit. The highest proportions with 'unmet need' were decedents with chronic obstructive pulmonary disease (31.0%) and heart failure (26.3%). Adjusting for sociodemographic and diagnostic factors, access was lowest among those aged <65 years (adjusted odds ratio (aOR) 0.44; 95% confidence interval (CI) 0.31-0.64) and those with heart failure (aOR 0.58; 95% CI 0.47-0.72). Conclusions Estimates of need and access provide a sound basis for planning local palliative and end-of-life care services. These methods can be used on an ongoing basis to monitor service delivery. What is known about this topic? There is a small but expanding literature on estimating the need for palliative care at a population level. There is a lack of data regarding access to palliative and other end-of-life care across multiple settings (e.g. home, specialist palliative care unit, hospital) and patient groups (e.g. defined by sociodemographics and diagnostics). What does this paper add? The study builds on previously used methods for estimating the need for palliative care, with some refinements, including the addition of 'other clinical indications' and the use of weights to derive more realistic estimates. The estimates of need are consistent with recent estimates from Australia and overseas, whereas the estimates of access are similar to a recent Australian estimate, but higher than estimates from overseas. The gaps in access are highest among those with the major types of chronic organ failure, particularly heart and respiratory. What are the implications for practitioners? The study demonstrates how routinely collected data at a regional level can be used to estimate need and access to palliative and end-of-life care, in the hospital and in the community. These methods of estimating need and unmet need can be used to inform the planning and development of services, as well as to monitor progress with implementation of changes in service provision.

Organ transplantation and chronic disturbances in the health condition of the population – challenges and perspectives

End-stage organ failure cases are increasing around the World. Especially chronic kidney failure has been becoming a worldwide epidemic. Although available medical technology and human health resources capacity is enough to transplant organs and tissues to patients diagnosed with end-stage organ fail-ure, many people cannot access the transplantation services because of eco-nomic reasons and organ shortage. Thus, health care professionals should fo-cus on preventing chronic organ failures besides increasing the organ donor pool.

Study on the application value of MELD-Na, CLIF-C OFs, COSSH-ACLFs and NLR scoring systems in patients with hepatitis B virus related acute-on-chronic liver failure

To verify the accuracy of the model for end-stage liver disease-sodium (MELD-Na), chronic liver failure consortium organ failure score (CLIF-C OFs), Chinese Group on the Study of Severe Hepatitis B-Acute-on-chronic Liver Failure score (COSSH-ACLFs) and neutrophil-to-lymphocyte ratio (NLR) scoring systems in patients with hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF) and to explore its value in clinical application. The clinical data (gender, age, disease stage) and laboratory indicators [alanine transferase (ALT), glutamate transaminase (AST), total bilirubin (TBil), albumin (ALB), blood urea nitrogen (BUN), creatinine (Cr), serum sodium (Na), prothrombin activity (PTA), international standardized ratio (INR), neutrophils count (NEU) and lymphocytes count (LYM)] of 163 patients with HBV-ACLF from July 2010 to July 2018 in Tianjin Second People's Hospital were retrospectively analyzed. After 8 weeks of admission, the patients were divided into death group (90 cases) and survival group (73 cases) according to survival status. The MELD-Na, CLIF-C OFs, COSSH-ACLFs scores and NLR of death group and survival group were compared, and a multivariate Logistic regression analysis was used to analyze the independent risk factors for HBV-ACLF. Propensity score analysis was used to demonstrate the accuracy of the method and receiver operating characteristic curve (ROC) was used to analyze the diagnostic value of the independent risk factors. There were no significant differences in gender, disease stage, ALB, BUN, Cr, Na, NEU on admission between the two groups (all P > 0.05). The age [years old: 43.00 (34.00, 53.00) vs. 50.00 (42.50, 55.00)] and serum levels of ALT [U/L: 252.90 (61.43, 613.33) vs. 359.10 (115.15, 784.70)], AST [U/L: 146.15 (90.88, 449.30) vs. 237.80 (109.00, 635.05)], TBil [μmol/L: 265.10 (183.10, 347.60) vs. 307.50 (229.90, 405.55)] and INR [2.13 (1.91, 2.46) vs. 2.29 (2.02, 2.94)] in survival group were lower than those in death group and the PTA [%: 34.00 (28.00, 38.00) vs. 31.00 (24.00, 36.00)] and LYM [×109/L: 1.37 (0.72, 1.79) vs. 0.85 (0.51, 1.39)] levels were significantly higher than those in death group (both P < 0.05). The MELD-Na [17.99 (16.60, 19.63) vs. 19.16 (17.43, 20.80)], CLIF-C OFs [9.00 (8.00, 9.00) vs. 9.00 (9.00, 10.00)], COSSH-ACLFs [4.87 (4.63, 5.48) vs. 5.47 (5.07, 5.80)] and NLR [2.86 (2.21, 5.19) vs. 4.38 (2.54, 8.46)] were lower in survival group than those of the death group (all P < 0.05). Logistic regression analysis showed that CLIF-C OFs [odds ratio (OR) = 0.532, 95% confidence interval (95%CI) was 0.380-0.744, P < 0.05] and NLR (OR = 0.901, 95%CI was 0.835-0.972, P < 0.05) were the independent risk factors for the prognosis of HBV-ACLF. After propensity score matching, the data of 59 cases in each group were successfully matched, there were no significant differences in age, gender, disease stage, ALT, AST, TBil, ALB, BUN, Cr, Na, PTA, INR and NEU between the two groups (all P > 0.05), and statistically significant difference in the baseline LYM [×109/L: 1.35 (0.74, 1.73) vs. 0.81 (0.51, 1.30)] were found between the survival group and the death group. The CLIF-C OFs, COSSH-ACLFs scores and NLR were lower in survival group compared with those of the death group [CLIF-C OFs: 9.00 (8.00, 9.00) vs. 9.00 (8.00, 10.00), COSSH-ACLFs: 4.99 (4.69, 5.64) vs. 5.34 (5.03, 5.81), NLR: 2.85 (2.21, 5.72) vs. 4.38 (2.47, 10.20), all P < 0.05] and CLIF-C OFs (OR = 0.593, 95%CI was 0.401-0.878, P < 0.05) and NLR (OR = 0.593, 95%CI was 0.401-0.878, P < 0.05) were still as the independent risk factors for the prognosis of HBV-ACLF. The sensitivity of CLIF-C OFs ≥ 9 and NLR ≥ 3.14 to forecast the 8-week clinical outcome of HBV-ACLF patients were 76.7% and 67.1%, the specificity were 48.9% and 56.7%, and AUC were 0.662 and 0.623. CLIF-C OFs was combined with NLR to increase the specificity of forecasting the 8-week clinical outcome of HBV-ACLF patients to 77.8%. CLIF-C OFs and NLR scores are independent risk factors affecting the clinical outcome of HBV-ACLF, and have better clinical value in predicting the prognosis of HBV-ACLF. Combined application of the two scores will be more beneficial to the prognosis of HBV-ACLF.

MORPHOLOGICAL ORGAN REMODELLING CAUSED BY OPIOID ANALGESICS

Nowadays, there is an increasing tendency towards the number of patients addicted to opioid-related drugs, which are relatively freely available in pharmacies due to due to violations of the prescription regulations. Few analgesics have a competitive advantage compared to opioid analgesics, but their prolong taking can result in marked metabolic changes leading to the disability and mortality among opioid-addicted patients. This situation requires in-depth study of pathogenetic mechanisms underlying the development of multiple organ comorbidities. Our study presents the analysis of data in special literature on structural remodelling of body tissues over the period of psychoactive substance intake, and in particular opioid analgesics. It has been found out that that there is a direct correlation between the changes in organs and tissues and the duration of exposure and the dosage of opioid analgesics. According to the literature, the first changes occurred in the initial stages of experimental research. Prolonged exposure to opioid analgesics led to serious dystrophic changes, which then turned into destructive ones and manifested by cell destruction. Therefore, the problem of the impact produced by opioid substances on the morphological remodelling of organs and systems is of great medical and social irrelevance. Prolonged use of opioids contributes to the development of a chronic endogenous intoxication that results in chronic multiple organ failure. This severe condition results from morphological alterations, which play an important role in the pathogenesis of a number of diseases. A lot of issues concerning to organ remodelling due to long-term use of narcotic analgesics remain are still unclear. Therefore, studying the structure of organs under the impact of opioids is essential for medical researchers and clinicians in terms of the elaboration of the preventive measure and effective approaches in treating prolonged opioid addiction.

PCLIF-SOFA is a reliable outcome prognostication score of critically ill children with cirrhosis: an ESPNIC multicentre study

Background and aimsData on outcome of critically ill children with cirrhosis are scarce. We aimed to evaluate the prognostic accuracy of sequential organs scoring systems in children with cirrhosis admitted to Paediatric Intensive Care Units (PICU).MethodsWe performed a multicentre retrospective analysis of children with cirrhosis admitted into four European PICUs between 2011 and 2016. Investigators were members of the ESPNIC liver failure and support working group. Paediatric End-Stage Liver Disease (PELD) and paediatric chronic liver failure sequential organ failure assessment score (pCLIF-SOFA) diagnostic accuracy for 28- and 60-day liver transplantation, 28-day mortality and 60-day composite outcome (ie. death or liver transplantation) were tested.ResultsOne-hundred-and-thirty children were included. The main causes for PICU admission were acute-on-chronic liver failure (ACLF), gastrointestinal bleeding and sepsis. Twenty-nine percent died and 22.3% were transplanted by day-60 after PICU admission. On multivariable analysis, pCLIF-SOFA was the only predictor of mortality at day-28 and of composite outcome. Both pCLIF-SOFA and ACLF were independently associated with emergent liver transplantation. The pCLIF-SOFA score higher than 9 well predicted a 28-day mortality with a sensitivity of 87.8% and a specificity of 77.3%. A pCLIF-SOFA score higher than 7 was independently associated with liver transplantation on day-60. Stage 3 AKI assessed with KDIGO classification was significantly associated with 28-day mortality.ConclusionsHalf of critically ill cirrhotic children admitted to PICU either died or were transplanted within the initial 28-day period. On admission pCLIF-SOFA score accurately identify patients transplanted at day-28 and day-60 to those alive without LT and is associated with 28-day mortality and composite outcome at day-60.
