Bioactive Adrenomedullin in Dogs with Sepsis and Septic Shock: A Prospective, Case-Control Study

Sepsis and septic shock are leading causes of morbidity and mortality in both humans and dogs, and early diagnosis is crucial for improving outcomes. This study aimed to evaluate bioactive adrenomedullin (bio-ADM) concentrations in dogs with septic shock (n = 25), dogs with sepsis without evidence of shock (n = 25), and healthy control dogs (n = 25). Plasma bio-ADM concentrations were measured using a human sandwich enzyme-linked immunosorbent assay and reported as median (interquartile range). Plasma bio-ADM concentrations were significantly higher in both septic groups compared to the healthy controls (all <22.4 pg/mL), but not significantly different between the septic shock (75.0 [28.7–115.0] pg/mL) and sepsis (30.7 [22.4–79.7] pg/mL) groups. Dogs with higher illness severity scores had significantly higher bio-ADM concentrations (93.1 [32.2–122.0] pg/mL) than those with lower scores (29.8 [22.4–71.2] pg/mL). However, bio-ADM concentrations did not differ between survivors (33.0 [22.7–76.7] pg/mL) and non-survivors (74.7 [26.1–123.2] pg/mL). Measurement of bio-ADM is a potential marker for canine sepsis, but not for the identification of septic shock, and may provide information on disease severity. Further studies, including those on non-infectious inflammatory conditions, are necessary to better understand the diagnostic utility of bio-ADM measurement and its potential role as a marker of treatment response in dogs with sepsis.

The impact of language barriers & interpreters on critical care patient outcomes

BackgroundIn a multicultural society, the impact of language proficiency and interpreter use on critical care patient outcomes is unknown. ObjectiveTo investigate the relationship between English language preference, requirement for an interpreter and in-hospital mortality amongst non-elective intensive care unit (ICU) patients. MethodAdult patients admitted to all 23 public ICUs within the state of Victoria, Australia from July 2007 to June 2018, were extracted from The Australian New Zealand Intensive Care Society Adult Patient Database. De-identified patient data was matched using probabilistic methods and statistical linkage keys to the Victorian Admitted Episodes Database. Patients were classified into one of three groups: ‘English preferred’, ‘English not preferred’ and ‘Interpreter required’. Results126,891 ICU admissions were analysed, of whom 3394 (3%) were in the ‘English not preferred’ group and 6355 (5%) in the ‘Interpreter required’ group. Compared to the ‘English preferred’, both the ‘English not preferred’ and ‘Interpreter required’ groups were older, had more co-morbidities and higher severity of illness scores. In-hospital mortality was 13.1% in the ‘English preferred’ group, 19.6% in the ‘English not preferred’ group and 16.7% in the ‘Interpreter required’ group. However, after adjusting for sex, severity of illness and socio-economic status, the ‘English not preferred’ group remained with a higher risk adjusted mortality (OR 1.21, 95%CI 1.07–1.36, P = 0.002), whereas the ‘Interpreter required’ group had a lower adjusted risk of mortality (OR 0.81, 95%CI 0.74–0.89, P < 0.001). ConclusionBeing identified as having a requirement for an interpreter was associated with improved outcomes for adults admitted to public hospital ICUs in Victoria. Interpreter services should be more readily available in the hospital setting. It is recommended that patients, family members and clinicians actively use interpreter services when English is not the preferred language of an ICU patient.

Clinical profile of schizophrenia comorbid with obsessive-compulsive symptoms: A comparative study

ObjectiveDescribe and compare the clinical profile of schizophrenic patients with and without obsessive-compulsive symptoms and obsessive-compulsive disorder (OCD) patients. MethodsA descriptive and analytical cross-sectional study was carried out at the psychiatry department of Hassan II University Hospital in Fez over 12 months to compare three groups of patients: “schizo-obsessive” (n=32), “schizophrenia” (n=34), and “OCD” (n=46). All participants (n=112) were assessed using the mini-international neuropsychiatric interview (MINI), the Yale-Brown obsessive-compulsive scale (Y-BOCS), the Brown assessment of beliefs scale (BABS), the Hamilton anxiety rating scale (HAM-A), the Beck's depression inventory (BDI-II), the positive and negative syndrome scale (PANSS), and the clinical global impressions–severity scale (CGI-S). ResultsThe “schizo-obsessive” group differed from the “schizophrenia” group in: more severe psychotic symptoms (mean=64.16±17.049, P<0.001), higher anxiety (mean=8.87±5,655, P<0.001) and depression (mean=7.50±5.989, P<0.001) scores, more prevalent suicide attempts (46.9%), higher illness severity score (mean=5.13±1.157, P=0.02), and more professional disinsertion (78.1%). The “schizo-obsessive” group (mean= 14.47±3.388) had significantly poor insight (P<0.001) compared to the “OCD” group (mean= 8.35±4.542). There were similarities in the obsessive and compulsive themes between the “schizo-obsessive” and the “OCD” groups, with no significant difference of severity (P=0.26). ConclusionA careful assessment of obsessive symptomatology is essential in schizophrenia for better patient management and prognosis.

Right ventricular strain measurements in critically ill patients: an observational SICS sub-study

BackgroundRight ventricular (RV) dysfunction is common in critically ill patients and is associated with poor outcomes. RV function is usually evaluated by Tricuspid Annular Plane Systolic Excursion (TAPSE) which can be obtained using critical care echocardiography (CCE). Myocardial deformation imaging, measuring strain, is suitable for advanced RV function assessment and has widely been studied in cardiology. However, it is relatively new for the Intensive Care Unit (ICU) and little is known about RV strain in critically ill patients. Therefore, the objectives of this study were to evaluate the feasibility of RV strain in critically ill patients using tissue-Doppler imaging (TDI) and explore the association between RV strain and conventional CCE measurements representing RV function.MethodsThis is a single-center sub-study of two prospective observational cohorts (Simple Intensive Care Studies (SICS)-I and SICS-II). All acutely admitted adults with an expected ICU stay over 24 h were included. CCE was performed within 24 h of ICU admission. In patients in which CCE was performed, TAPSE, peak systolic velocity at the tricuspid annulus (RV s’) and TDI images were obtained. RV free wall longitudinal strain (RVFWSL) and RV global four-chamber longitudinal strain (RV4CSL) were measured during offline analysis.ResultsA total of 171 patients were included. Feasibility of RVFWSL and RV4CSL was, respectively, 62% and 56% in our population; however, when measurements were performed, intra- and inter-rater reliability based on the intraclass correlation coefficient were good to excellent. RV dysfunction based on TAPSE or RV s’ was found in 56 patients (33%) and 24 patients (14%) had RV dysfunction based on RVFWSL or RV4CSL. In 14 patients (8%), RVFWSL, RV4CSL, or both were reduced, despite conventional RV function measurements being preserved. These patients had significantly higher severity of illness scores. Sensitivity analysis with fractional area change showed similar results.ConclusionsTDI RV strain imaging in critically ill patients is challenging; however, good-to-excellent reproducibility was shown when measurements were adequately obtained. Future studies are needed to elucidate the diagnostic and prognostic value of RV strain in critically ill patients, especially to outweigh the difficulty and effort of imaging against the clinical value.

DEVELOPMENT AND VALIDATION OF A CLINICAL DECISION-SUPPORT TOOL FOR PREDICTION OF WEANING OUTCOME ON ADMISSION TO THE ICU

DEVELOPMENT AND VALIDATION OF A CLINICAL DECISION-SUPPORT TOOL FOR PREDICTION OF WEANING OUTCOME ON ADMISSION TO THE ICU

Older adults with severe coronavirus disease 2019 admitted to intensive care unit: prevalence, characteristics and risk factors for mortality.

Although older adults are at high risk for severe coronavirus disease 2019 (COVID-19) requiring intensive care unit (ICU) admission, age is often used as a selection criterion in case of ICU beds scarcity. We sought to compare the proportion, clinical features and mortality between patients ≥70 years old and younger ICU patients with COVID-19. All patients, consecutively admitted to our COVID ICU, where age was not used as an admission criterion, from March 2020 through April 2021, were included. Demographics, clinical and laboratory characteristics were recorded. Illness severity and Charlson comorbidity Index (CCI) were calculated. Patients≥70 years old were compared to youngers. Of 458 patients (68 [59-76] years, 70% males), 206 (45%) were ≥70 years old. Compared to younger, older patients had higher illness severity scores (APACHE II 18 [14-23] versus 12 [9-16], P<0.001, SOFA 8 [6-10] versus 6 [2-8], P<0.001, CCI 5 [4-6] versus 2 [1-3], P<0.001), increased need for mechanical ventilation (92% vs. 72%, P<0.001) and ICU mortality (74% versus. 29%, P<0.001). Age (HR: 1.045, CI: 1.02-1.07, P=0.001), CCI (HR: 1.135, CI: 1.037-1.243, P=0.006) and APACHE II (HR: 1.070, CI: 1.013-1.130, P=0.015) were independently associated with mortality. Among comorbidities, obesity, chronic pulmonary disease and chronic kidney disease were independent risk factors for death. When age is not used as criterion for admission to COVID ICU, patients ≥70 years old represent a considerable proportion and, compared to younger ones, they have higher mortality. Age, severity of illness and CCI, and certain comorbidities are independent risk factors for mortality.

Specific characteristics and current diagnostic and treatment modalities performance of super refractory status epilepticus in children: A comparative study

Super-refractory status epilepticus (SRSE) is associated with significant morbidity and mortality in children. We explored the clinical spectrum, specific characteristics, and outcome in SRSE patients admitted in a pediatric intensive care unit (PICU) and investigated how well current diagnostic or treatment modalities perform compared to Status Epilepticus (SE) and Refractory SE (RSE) patients. Retrospective analysis of PICU patients admitted with convulsive SE during 2009-2019. Eighty-six patients were classified as SE, RSE, and SRSE. New-onset RSE (NORSE) and febrile infection-related epilepsy syndrome (FIRES) were also identified. Functional outcome was evaluated by the modified Rankin scale. Patients with SRSE (n=20) had longer weaning off anesthetics (p=0.014), length of stay, mechanical ventilation duration, higher illness severity scores, and poorer outcome compared to SE (n=13) or RSE (n=53) patients (all p<0.001). Diagnosis, mainly expressed by high prevalence of NORSE (n=13) and FIRES (n=9), was independently associated with SRSE (p=0.024). Abnormal MRI findings (p=0.005), and epilepsy-related pathogenic variants identified by whole-exome sequencing (WES) were mostly found in SRSE patients. Compared to intravenous immunoglobulins and steroid pulses, plasmapheresis and ketogenic diet, more often used in SRSE (p<0.01), contributed better to seizure control. Only SRSE (AUROC > 0.80, 95% CI=0.68-0.94, p<0.001) and diagnosis (AUROC > 0.70, 95% CI=0.55-0.83, p=0.02) could predict a poor outcome. The majority of SRSE patients are characterized by considerable functional decline and morbidity. WES analysis may reveal epilepsy-related pathogenic variants while early aggressive immunotherapy and/or ketogenic diet might prove beneficial. Multicenter studies for prediction models of outcome are needed.

Determinants of maternal mortality in a critical care unit: A prospective analysis.

Introduction:An admission of a pregnant woman to an intensive care unit (ICU) is considered as an objective marker of maternal near miss. Only a few studies from the Indian subcontinent have reported on the ability of ICU scoring systems in predicting the mortality in obstetric patients.Methods:A prospective analysis of all critically ill obstetric patients admitted to the critical care department was done.Results:In the period between April 2013 and September 2017, there were 101 obstetric admissions to the critical care ICU. Of these, 82 patients (81.2%) were discharged from the hospital, 18 patients (17.8%) died, and one left against medical advice. The common diagnoses seen in these patients were cardiac failure (n = 39; 38.6%); pregnancy-induced hypertension (n = 26; 25.7%); acute respiratory distress syndrome (n = 20; 19.8%); intra-abdominal sepsis (n = 19; 18.8%); tropical diseases (n = 19; 18.8%); and tuberculosis (n = 13; 12.9%). When we compared the survivors with the nonsurvivors, a higher severity of illness score and a low PaO2/FiO2 were found to increase the odds of death. The area of distribution under the receiver operator characteristic curve was 0.726 (95% confidence interval [CI] = 0.575–0.877), 0.890 (95% CI = 0.773–1.006), 0.867 (95% CI = 0.755–0.979), and 0.850 (95% CI = 0.720–0.980) for the PaO2/FiO2, Simplified Acute Physiology Score (SAPS) II, Sequential Organ Failure Assessment and Acute Physiology and Chronic Health Evaluation (APACHE) II score, respectively, for predicting mortality. The standardized mortality ratio was better with SAPSII than with APACHE II.Conclusions:Cardiac dysfunction is a leading cause of ICU admission. Obstetric patients frequently require ventilatory support, intensive hemodynamic monitoring, and blood transfusion. The APACHE II score is a good index for assessing ICU outcomes.

193. Evaluation of Severity Scores in Patients with Methicillin-Susceptible Staphylococcus aureus Bloodstream Infections

Abstract Background Staphylococcus aureus bloodstream infections (BSIs) are associated with increased morbidity, mortality, and healthcare costs. Severity of illness scores help stratify critically ill patients and assist providers in making decisions. The quick Pitt (qPitt) score is a reliable predictor of mortality in patients with Gram-negative BSIs (AUROC 0.85); however, limited data exist for using the qPitt in methicillin-susceptible S. aureus (MSSA) BSIs. Methods This retrospective cohort evaluated patients with MSSA BSIs. The primary outcome was the discrimination of the qPitt in predicting hospital mortality compared to the Pitt bacteremia score (PBS). Secondary outcomes were clinical failure and the predictive discrimination of the qPitt score in comparison to other severity scoring modalities. Categorical data were analyzed using chi-square test or Fisher’s exact test. Continuous data were analyzed using Student’s t-test or Mann-Whitney U. Predictive discrimination was determined by the area under receiver operating characteristic curve. Results One hundred patients were included with the mean age of 52 years (p=0.84) and a BMI of 30 kg/m2. Males were predominant (70%). Mortality occurred in 13 patients who had more ICU admissions (92% vs. 37%; p&amp;lt; 0.01) and longer ICU LOS (10 vs. 5 days; p=0.03) despite similar baseline comorbidities. Time to definitive therapy was longer in the mortality group than non-mortality group (28 vs. 23 hours; p=0.79) though antimicrobial use did not differ. As outlined in Figure 1, the mortality group had higher severity of illness scores. The qPitt had a ROC of 0.83, indicating high discrimination. Overall, qPitt was found to be similarly predictive than PBS, equally as predictive as qSOFA, and more predictive than SIRS and APACHE II (Figure 1). Clinical failure occurred in 23% of patients; 54% of the mortality group experienced persistent BSI vs. 11% in the non-mortality group (p&amp;lt; 0.01), and 3% of the non-mortality group had recurrent infection (p=1.00). Conclusion Compared to previous studies on Gram-negative BSIs, the qPitt performed similarly in MSSA BSIs. The qPitt can be considered for use in predicting mortality for patients with MSSA BSIs; however, further studies are needed to confirm these results.

Risk Factors Associated with Mechanical Ventilation in Critical Bronchiolitis.

The American Academy of Pediatrics (AAP) recommends supportive care for the management of bronchiolitis. However, patients admitted to the intensive care unit with severe (critical) bronchiolitis define a unique group with varying needs for both non-invasive and invasive respiratory support. Currently, no guidance exists to help clinicians discern who will progress to invasive mechanical support. Here, we sought to identify key clinical features that distinguish pediatric patients with critical bronchiolitis requiring invasive mechanical ventilation from those that did not. We conducted a retrospective cohort study at a tertiary pediatric medical center. Children ≤2 years old admitted to the pediatric intensive care unit (PICU) from January 2015 to December 2019 with acute bronchiolitis were studied. Patients were divided into non-invasive respiratory support (NRS) and invasive mechanical ventilation (IMV) groups; the IMV group was further subdivided depending on timing of intubation relative to PICU admission. Of the 573 qualifying patients, 133 (23%) required invasive mechanical ventilation. Median age and weight were lower in the IMV group, while incidence of prematurity and pre-existing neurologic or genetic conditions were higher compared to the NRS group. Multi-microbial pneumonias were diagnosed more commonly in the IMV group, in turn associated with higher severity of illness scores, longer PICU lengths of stay, and more antibiotic usage. Within the IMV group, those intubated earlier had a shorter duration of mechanical ventilation and PICU length of stay, associated with lower pathogen load and, in turn, shorter antibiotic duration. Taken together, our data reveal that critically ill patients with bronchiolitis who require mechanical ventilation possess high risk features, including younger age, history of prematurity, neurologic or genetic co-morbidities, and a propensity for multi-microbial infections.

The effect of dobutamine in sepsis: a propensity score matched analysis

BackgroundThe use of dobutamine in patients with sepsis is questionable currently. As the benefit of dobutamine in septic patients is unclear, we aimed to evaluate whether the use of dobutamine was associated with decreased hospital mortality in sepsis patients.MethodsBased on the analysis of MIMIC III public database, we performed a big-data, real world study. According to the use of dobutamine or not, patients were categorized as the dobutamine group or non dobutamine group.We used propensity score matched (PSM) analysis to adjust for confoundings. The primary outcome was hospital mortality.ResultsIn the present study, after screening 38,605 patients, 2826 patients with sepsis were included. 121 patients were in dobutamine group and 2165 patients were in non dobutamine group. Compared with patients in non-dobutamine group, patients in dobutamine group had a lower MAP, higher HR, higher RR, higher severity of illness scores. 72 of 121 patients (59.5%) in the dobutamine group and 754 of 2165 patients (34.8%) in the non-dobutamine group died in the hospital, which resulted in a significant between-group difference (OR 1.56, 95% CI 1.01–2.40; P = 0.000). For the secondary outcomes, patients in dobutamine group received more MV use, more renal replacement therapy use, had longer ICU stay durations and more cardiac arrhythmias than those in non-dobutamine group. After adjusting for confoundings between groups by PSM analysis, hospital mortality was consistently higher in dobutamine group than that in non-dobutamine group (60.2% vs. 49.4%, OR 1.55, 95% CI 1.01–2.37; P = 0.044).ConclusionsAmong patients with sepsis, our study showed that the use of dobutamine was not associated with decreased hospital mortality. Further large scale, randomized controlled studies are warrented to confirm our findings.

Clinical features, outcome, and illness severity scoring in 32 dogs with urosepsis (2017-2018).

To describe the clinical features, outcome, and utility of illness severity scoring in dogs diagnosed with urosepsis. Retrospective study (2017-2018). University teaching hospital. Thirty-two dogs diagnosed with urosepsis secondary to pyometra, prostatitis, or pyelonephritis. None. Urosepsis was identified in 32 dogs, consisting of 9 of 32 (28.1%) with pyometra, 7 of 32 (21.8%) with prostatitis, and 16 of 32 (50%) with pyelonephritis. In total, 28 (87.5%) dogs survived to discharge, with the following group-specific survival rates: pyometra, 9 of 9 (100%); prostatitis, 5 of 7 (71.4%); and pyelonephritis, 14 of 16 (87.5%). Positive bacterial cultures were obtained in 27 of 32 (84.1%) dogs. The most commonly implicated pathogens were Escherichia coli (14/37 [37.8%]), Klebsiella pneumoniae (8/37 [21.6%]), and Staphylococcus pseudintermedius (6/37 [16.2%]). Multiple organ dysfunction syndrome (MODS) was identified in 21 of 32 dogs (65.6%). Although the presence of MODS was not different between survivors and nonsurvivors (P=0.6), nonsurvivors had more dysfunctional organs (P=0.04). Nonsurvivors also had higher Acute Patient Physiology and Laboratory Evaluation (APPLEFAST ) scores compared to survivors (P=0.01). Survival of dogs with urosepsis was good and may be higher than for other sources of sepsis. Compared to survivors, nonsurvivors had more dysfunctional organs and higher illness severity scores, which may be helpful in the assessment and management of dogs with urosepsis.

Association between the modified Nutrition Risk in Critically Ill (mNUTRIC) score and clinical outcomes in the intensive care unit: a secondary analysis of a large prospective observational study

BackgroundMalnutrition in intensive care unit (ICU) patients is associated with adverse clinical outcomes. The modified nutrition risk in the critically ill score (mNUTRIC) was proposed as an appropriate nutritional assessment tool in critically ill patients, but it has not been fully demonstrated and widely used. Our study was conducted to identify the nutritional risk in ICU patients using the mNUTRIC score and explore the relationship between 28-day mortality and high mNUTRIC scores.MethodsThis study is a secondary analysis, the data were extracted from The Beijing Acute Kidney Injury Trial (BAKIT). In total, 9049 patients were admitted consecutively, and 3107 patients with complete clinical data were included in this study. We divided the study population into high nutritional risk (mNUTRIC score ≥ 5 points) and low nutritional risk (mNUTRIC score < 5 points) groups. The predictive capacity of the mNUTRIC score was studied by receiver operating characteristic (ROC) curve analysis, appropriate cut-off was identified by highest combined sensitivity and specificity using Youden’s index. The significance level was set at 5%.ResultsAmong the 3107 patients, the 28-day mortality rate was 17.4% (540 patients died). Nearly 28.2% of patients admitted to the ICU were at risk of malnutrition, high nutritional risk patients were older (P < 0.001), with higher illness severity scores than low nutritional risk patients. Multivariate analysis revealed that the mNUTRIC score was an independent risk factor for 28-day mortality and mortality increased with increasing scores (p = 0.000). The calculated area under curve (AUC) for the mNUTRIC score was 0.763 (CI 0.740–0.786). According to Youden’s index, we found a suitable cut-off > 4 for the mNUTRIC score to predict the 28-day mortality.ConclusionsPatients admitted to the ICU were at high risk of malnutrition, and a high mNUTRIC score was associated with increased ICU length of stay and higher mortality. More large prospective studies are needed to demonstrate the validity of this score.Trial registrationThis study was registered at www.chictr.org.cn (registration number Chi CTR-ONC-11001875). Registered on 14 December 2011.

Short-term and intermediate-term readmission after esophagectomy.

BackgroundThe objective of this study was to characterize short- and intermediate-term readmissions following esophagectomy and to identify predictors of readmission in these two groups.MethodsPatients who underwent esophagectomy in the National Readmissions Database (2013–2014) were grouped according to whether first readmission was “short-term” (readmitted <30 days) or “intermediate-term” (readmitted 31–90 days) following index admission for esophagectomy. Predictors of readmission were evaluated using multivariable logistic regression modeling.ResultsOf the 3,005 patients who underwent esophagectomy, 544 (18.1%) had a short-term readmission and 305 (10.1%) had an intermediate-term readmission. The most frequent reasons for short-term readmission were post-operative infection (7.5%), dysphagia (6.3%) and pneumonia (5.1%). The most common intermediate-term complications were pneumonia (7.2%), gastrointestinal stricture/stenosis (6.9%) and dysphagia (5.9%). In multivariable analysis, being located in a micropolitan area, increasing number of comorbidities and higher severity of illness score were associated with an increased likelihood of having a short-term readmission while being discharged to a facility (as opposed to directly home) was associated with increased likelihood of both short- and intermediate-term readmission (all P<0.05).ConclusionsIn this analysis, postoperative infection was the most common reason for short-term readmission. Dysphagia and pneumonia were common reasons for both short- and intermediate-term readmission of patients following esophagectomy. Interventions focused on reducing the risk of postoperative infection and pneumonia may reduce hospital readmissions. Gastrointestinal stricture and dysphagia were associated with increased risk of intermediate readmission and should be examined in the context of morbidity associated with pyloric procedures (e.g., pyloromyotomy) at the time of esophagectomy.

Incidence, Clinical Characteristics and Outcomes of Early Hyperbilirubinemia in Critically Ill Patients: Insights From the MARS Study.

ABSTRACTObjective:To investigate the incidence, clinical characteristics and outcomes of early hyperbilirubinemia in critically ill patients.Design and Setting:This is a post hoc analysis of a prospective multicenter cohort study.Patients:Patients with measured bilirubin levels within the first 2 days after ICU admission were eligible. Patients with liver cirrhosis were excluded.Endpoints:The primary endpoint was the incidence of early hyperbilirubinemia, defined as bilirubin ≥33 μmol/L within 2 days after ICU admission. Secondary endpoints included clinical characteristics of patients with versus patients without early hyperbilirubinemia, and outcomes up to day 30.Results:Of 4,836 patients, 559 (11.6%) patients had early hyperbilirubinemia. Compared to patients without early hyperbilirubinemia, patients with early hyperbilirubinemia presented with higher severity of illness scores, and higher incidences of sepsis and organ failure. After adjustment for confounding variables, early hyperbilirubinemia remained associated with mortality at day 30 (odds ratio, 1.31 [95%–confidence interval 1.06–1.60]; P = 0.018). Patients with early hyperbilirubinemia and thrombocytopenia (interaction P-value = 0.005) had a higher likelihood of death within 30 days (odds ratio, 2.61 [95%–confidence interval 2.08–3.27]; P < 0.001) than patients with early hyperbilirubinemia and a normal platelet count (odds ratio, 1.09 [95%–confidence interval 0.75–1.55]; P = 0.655).Conclusions:Early hyperbilirubinemia occurs frequently in the critically ill, and these patients present with higher disease severity and more often with sepsis and organ failures. Early hyperbilirubinemia has an association with mortality, albeit this association was only found in patients with concomitant thrombocytopenia.

Outcome of very preterm infants delivered outside tertiary perinatal centers in China: a multi-center cohort study.

BackgroundTo describe the incidence of outborns among very preterm infants (VPIs, <32 weeks of gestation) in Chinese perinatal centers and to examine the association of outborn status with adverse outcomes.MethodsA cohort study enrolling all VPIs admitted to 18 perinatal centers in China from May 1st, 2015 to April 30th, 2018. Neonatal outcomes including rates of discharge against medical advice (DAMA), in-hospital mortality, overall mortality, severe intraventricular hemorrhage (IVH) or periventricular leukomalacia (PVL), sepsis, bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC) and severe retinopathy of prematurity (ROP) were compared between outborn and inborn infants. A multivariate logistic regression model was used to estimate the independent association of outborn status with neonatal outcomes.ResultsAmong 12,014 VPIs, 1,991 (16.6%) infants were outborn. Outborn infants had lower Apgar scores and higher illness severity score on admission. Mothers of outborn infants were less likely to receive antenatal steroids, prenatal care and caesarean section. The incidence of DAMA (18.0% vs. 12.5%, P<0.001), overall mortality (19.9% vs. 15.8%, P<0.001) and severe brain injury (10.8% vs. 9.1%, P=0.024) of outborn infants were significantly higher than inborn infants. Outborn status was independently associated with increased risks of DAMA (aOR, 1.6; 95% CI: 1.4–1.8), overall-hospital mortality (aOR, 1.3; 95% CI: 1.1–1.5) and severe IVH/PVL (aOR, 1.2; 95% CI: 1.0–1.5).ConclusionsThe incidence of outborn VPIs was high in China. Outborn infants were more likely to be delivered in an uncontrolled situation and were at significantly higher risk of neonatal mortality and severe brain injury compared with inborn infants. Quality improvement efforts are needed to facilitate in-utero transfer of high-risk pregnancies to tertiary centers.

Trends in Abusive and Nonabusive Injury Hospitalizations in Young Children in Texas, 2004-2018.

Hospitalization data provide context to understanding abusive and non-abusive injuries and how these hospitalizations change over time. The purpose of this study was to utilize Texas inpatient hospitalization data to assess age-related differences among infants (<12 months of age) and toddlers (12-59 months of age) in injury trends and patterns of injury among abusive and non-abusive hospitalization encounters over a 15-year time period. For both age groups, pediatric hospitalizations for non-abusive injuries decreased significantly over time; however, hospitalizations for abusive injuries did not. Compared to non-abusive injury hospitalizations, abusive injury hospitalizations were statistically more likely to involve more body regions and were associated with fractures, internal organ injuries, and superficial wounds. Abusive injury hospitalizations had longer lengths of stay and resulted in higher illness severity scores. Toddler injury hospitalizations were associated with most of the body regions, with the exception of traumatic brain injury for which the odds of hospitalization were higher for infants. This study confirms the persistence of abusive injury hospitalizations and the age-related susceptibility to certain injuries comparing infants and toddlers. The findings reflect the clinical documentation and decision making of pediatric practitioners in a large state over 15 years and inform the trends in identification of injuries which are most common and consistent by age and intent.

Early Treatment with Human Albumin Solution in Continuous Renal Replacement Patients

Aims: To study the impact of early human albumin solution (HAS) in continuous renal replacement therapy (RRT) patients. Methods: Analysis of Randomized Evaluation of Normal versus Augmented Level (RENAL) RRT trial data. Results: Of 1,464 patients, 500 (34%) received early albumin. These patients had higher illness severity scores, greater use of mechanical ventilation, and 90-day mortality (51 vs. 41%; p < 0.001). However, early albumin carried similar RRT dependence risk among survivors at day 90 (4.9 vs. 5.8%; p = 0.62). On Cox proportional hazards regression, with standardized inverse probability of treatment weighting, early albumin was not associated with increased mortality (hazard ratio [HR]: 1.23, 95% CI: 0.97–1.55; p = 0.09) or recovery to RRT independence (HR: 0.92, 95% CI: 0.78–1.10; p = 0.38). Conclusions: Early albumin was administered to one-third of RENAL trial patients and in those with greater illness severity. Early albumin was not independently associated with mortality risk or rate of recovery to RRT independence.

Inhibitory Immune Checkpoint Molecule Expression in Clinical Sepsis Studies: A Systematic Review.

Checkpoint inhibitors have been proposed for sepsis following reports of increased checkpoint molecule expression in septic patients. To determine whether clinical studies investigating checkpoint molecule expression provide strong evidence supporting trials of checkpoint inhibitors for sepsis. PubMed, EMBASE, Scopus, Web of Science, inception through October 2019. Studies comparing checkpoint molecule expression in septic patients versus healthy controls or critically ill nonseptic patients or in sepsis nonsurvivors versus survivors. Two investigators extracted data and evaluated study quality. Thirty-six studies were retrieved. Across 26 studies, compared with healthy controls, septic patients had significantly (p ≤ 0.05) increased CD4+ lymphocyte programmed death-1 and monocyte programmed death-ligand-1 expression in most studies. Other checkpoint molecule expressions were variable and studied less frequently. Across 11 studies, compared with critically ill nonseptic, septic patients had significantly increased checkpoint molecule expression in three or fewer studies. Septic patients had higher severity of illness scores, comorbidities, and mortality in three studies providing analysis. Across 12 studies, compared with septic survivors, nonsurvivors had significantly increased expression of any checkpoint molecule on any cell type in five or fewer studies. Of all 36 studies, none adjusted for nonseptic covariates reported to increase checkpoint molecule expression. Although sepsis may increase some checkpoint molecule expression compared with healthy controls, the data are limited and inconsistent. Further, data from the more informative patient comparisons are potentially confounded by severity of illness. These clinical checkpoint molecule expression studies do not yet provide a strong rationale for trials of checkpoint inhibitor therapy for sepsis.
