Abstract
This study investigates the prognostic impact of left ventricular ejection fraction (LVEF) and tricuspid annular plane systolic excursion (TAPSE) in patients with sepsis and septic shock. Consecutive patients with sepsis and septic shock were included from 2019 to 2021. LVEF and TAPSE were assessed during the first 24 hours of intensive care unit (ICU) treatment. Patients were stratified by LVEF of less than 45% and greater than or equal to 45%. The primary endpoint was 30 day all-cause mortality. Two hundred ninety-two consecutive patients were included, of which 26% presented with LVEF of less than 45%. Within the entire study cohort (60% vs. 48%; hazard ratio [HR] = 1.414; 95% confidence interval [CI] = 0.999-2.001; p = 0.050) and specifically in patients with sepsis (58% vs. 36%; HR = 1.919; 95% CI = 1.148-3.208; p = 0.013), LVEF of less than 45% was associated with an increased risk of 30 day all-cause mortality, whereas TAPSE of less than 17 mm was not (56% vs. 52%; log rank p = 0.798). Even after multivariable adjustment, LVEF of less than 45% was accompanied by a worse prognosis in septic patients (HR = 1.944; 95% CI = 1.084-3.485; p = 0.026). Contrarily, LVEF < 45% was not accompanied with increased mortality in septic shock patients (63% vs. 67%; log rank p = 0.847; HR = 0.956; 95% CI 0.596-1.533; p = 0.853). In conclusion, impaired LVEF was associated with increased mortality in septic patients without shock, but not in patients with septic shock. In contrast, impaired right ventricular function was not associated with adverse prognosis in both conditions.

Abstract
Purpose: The objective of this study was to explore the relationship between elevated B-type natriuretic peptide (BNP) levels and the prognosis of patients with infective endocarditis (IE) undergoing cardiac surgery. Methods: In total, 162 IE patients with recorded BNP levels upon admission were included in the present study. The primary end point was all-cause mortality. Results: Multivariate Cox analysis revealed a significant association between log BNP and all-cause mortality. Kaplan-Meier analysis revealed a poorer prognosis for patients with BNP levels ≥ the 75th percentile. Furthermore, the linear trend test indicated a significant link between BNP quartiles and the primary end point within the models. Conclusion: Elevated BNP levels upon admission could predict all-cause mortality in IE patients undergoing cardiac surgery.

Abstract
Millions of people were infected by the coronavirus disease (COVID-19) epidemic, which left a huge burden on the care of post COVID-19 survivors around the globe. The self-reported COVID-19 symptoms were experienced by an estimated 1.3 million people in the United Kingdom (2% of the population), and these symptoms persisted for about 4 weeks from the beginning of the infection. The symptoms most frequently reported were exhaustion, shortness of breath, muscular discomfort, joint pain, headache, cough, chest pain, cognitive impairment, memory loss, anxiety, sleep difficulties, diarrhea, and a decreased sense of smell and taste in post-COVID-19 affected people. The post COVID-19 complications were frequently related to the respiratory, cardiac, nervous, psychological and musculoskeletal systems. The lungs, liver, kidneys, heart, brain and other organs had been impaired by hypoxia and inflammation in post COVID-19 individuals. The upregulation of substance "P" (SP) and various cytokines such as tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL-6), interleukin 10 (IL-10), interleukin 1 beta (IL-1β), angiotensin-converting enzyme 2 (ACE2) and chemokine C-C motif ligand 3 (CCL3) has muddled respiratory, cardiac, neuropsychiatric, dermatological, endocrine, musculoskeletal, gastrointestinal, renal and genitourinary complications in post COVID-19 people. To prevent these complications from worsening, it was therefore important to study how these biomarkers were upregulated and block their receptors.

Abstract
CONTEXT.— Disease courses in COVID-19 patients vary widely. Prediction of disease severity on initial diagnosis would aid appropriate therapy, but few studies include data from initial diagnosis. OBJECTIVE.— To develop predictive models of COVID-19 severity based on demographic, clinical, and laboratory data collected at initial patient contact after diagnosis of COVID-19. DESIGN.— We studied demographic data and clinical laboratory biomarkers at time of diagnosis, using backward logistic regression modeling to determine severe and mild outcomes. We used deidentified data from 14 147 patients who were diagnosed with COVID-19 by polymerase chain reaction SARS-CoV-2 testing at Montefiore Health System, from March 2020 to September 2021. We generated models predicting severe disease (death or more than 90 hospital days) versus mild disease (alive and fewer than 2 hospital days), starting with 58 variables, by backward stepwise logistic regression. RESULTS.— Of the 14 147 patients, including Whites, Blacks, and Hispanics, 2546 (18%) patients had severe outcomes and 3395 (24%) had mild outcomes. The final number of patients per model varied from 445 to 755 because not all patients had all available variables. Four models (inclusive, receiver operating characteristic, specific, and sensitive) were identified as proficient in predicting patient outcomes. The parameters that remained in all models were age, albumin, diastolic blood pressure, ferritin, lactic dehydrogenase, socioeconomic status, procalcitonin, B-type natriuretic peptide, and platelet count. CONCLUSIONS.— These findings suggest that the biomarkers found within the specific and sensitive models would be most useful to health care providers on their initial severity evaluation of COVID-19.

Abstract
This study investigates the prognostic value of cardiac troponin I (cTNI) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in patients with cardiogenic shock (CS). Data regarding the prognostic value of cardiac biomarkers in CS is scarce, furthermore, most studies were restricted to CS patients with acute myocardial infarction (AMI). Therefore, consecutive patients with CS from 2019 to 2021 were included. Blood samples were retrieved from day of disease onset (day 1) and on days 2, 3 and 4 thereafter. The prognostic value of cTNI and NT-proBNP levels was tested for 30-day all-cause mortality. Statistical analyses included univariable t-tests, Spearman's correlations, Kaplan-Meier analyses and multivariable Cox proportional regression analyses. A total of 217 CS patients were included with an overall rate of all-cause mortality of 56% at 30 days. CTNI was able to discriminate 30-day non-survivors (area under the curve (AUC) = 0.669; p = 0.001), whereas NT-proBNP (AUC = 0.585; p = 0.152) was not. The risk of 30-day all-cause mortality was higher in patients with cTNI levels above the median (70% vs. 43%; log rank p = 0.001; HR = 2.175; 95% CI 1.510-3.132; p = 0.001), which was observed both in patients with (71% vs. 49%; log rank p = 0.012) and without AMI-related CS (69% vs. 40%; log rank p = 0.005). The prognostic impact of cTNI was confirmed after multivariable adjustment (HR = 1.915; 95% CI 1.298-2.824; p = 0.001). In conclusion, cTNI-but not NT-proBNP-levels discriminated 30-day all-cause mortality in CS patients.

Abstract
BACKGROUND C-type natriuretic peptide (CNP) is an endothelium-derived paracrine molecule with an important role in vascular homeostasis. In septic patients, the serum level of the amino-terminal propeptide of CNP (NT-proCNP) shows a strong positive correlation with inflammatory biomarkers and, if elevated, correlates with disease severity and indicates a poor outcome. It is not yet known whether NT-proCNP also correlates with the clinical outcome of patients suffering from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. In the current study, we aimed to determine possible changes in the NT-proCNP levels of patients with coronavirus disease 2019 (COVID-19), with special regard to disease severity and outcome. METHODS In this retrospective analysis, we determined the serum level of NT-proCNP in hospitalized patients with symptoms of upper respiratory tract infection, using their blood samples taken on admission, stored in a biobank. The NT-proCNP levels of 32 SARS-CoV-2 positive and 35 SARS-CoV-2 negative patients were measured to investigate possible correlation with disease outcome. SARS-CoV-2 positive patients were then divided into two groups based on their need for intensive care unit treatment (severe and mild COVID-19). RESULTS The NT-proCNP was significantly different in the study groups (e.g. severe and mild COVID-19 and non-COVID-19 patients), but showed inverse changes compared to previous observations in septic patients: lowest levels were detected in critically ill COVID-19 patients, while highest levels in the non-COVID-19 group. A low level of NT-proCNP on admission was significantly associated with severe disease outcome. CONCLUSIONS Low-level NT-proCNP on hospital admission is associated with a severe COVID-19 disease course. The pathomechanism underlying this observation remains to be elucidated, while future studies in larger patient cohorts are necessary to confirm these observations and reveal therapeutic importance.

Abstract
Sepsis is a systemic inflammatory response syndrome of suspected or documented infectious origin, whose outcome is multiorgan failure. Sepsis-induced myocardial dysfunction (SIMD), present in more than 50% of septic patients, is characterized by (i) left ventricular (LV) dilatation with normal or low filling pressure, (ii) right and/or LV (systolic and/or diastolic) dysfunction and (iii) reversibility. Since the first definition proposed by Parker et al. in 1984, attempts have been made to define SIMD. Many parameters are used to assess cardiac function in septic patients, sometimes making it more difficult to measure due to the intrinsic hemodynamical changes in this condition. Nevertheless, with advanced echocardiographic techniques, such as speckle tracking analysis, it is possible to diagnose and assess systolic and diastolic dysfunction, even in the earliest stages of sepsis. Cardiac magnetic resonance imaging brings new insights into the reversibility of this condition. Many uncertainties still remain regarding the mechanisms, characteristics, treatment and even prognosis of this condition. There are also inconsistent conclusions from studies, therefore this review attempts to summarize our current knowledge of SIMD.

Abstract
Data regarding the prognostic value of cardiac biomarkers in patients suffering from sepsis or septic shock is scarce. Studies investigating the prognostic role of cardiac biomarkers in patients with sepsis and septic shock were commonly published prior to the sepsis-3 criteria and were often not restricted to septic patients only, too. This study investigated the diagnostic and prognostic value of the aminoterminal pro-B-type Natriuretic Peptide (NT-pro BNP) and cardiac troponin I (cTNI) in patients with sepsis and septic shock. Consecutive patients with sepsis and septic shock were included from 2019 to 2021. Blood samples were retrieved from the day of disease onset (i.e., day 1), day 2 and 3. Firstly, the diagnostic value of the NT-pro BNP and cTNI to diagnose sepsis or septic shock was tested. Secondly, the prognostic value of the NT-pro BNP and cTNI was examined with regard to the 30-day all-cause mortality. The statistical analyses included univariable t-tests, Spearman’s correlations, C-statistics, Kaplan–Meier analyses and Cox proportional regression analyses. A total of 162 patients were included prospectively, of which 57% had a sepsis and 43% a septic shock. The overall rate of all-cause mortality at 30 days was 53%. With an area under the curve (AUC) of 0.658 on day 1 and 0.885 on day 3, cTNI expressed a better diagnostic value than NT-pro BNP, especially on day 3 (ΔAUCd3 = 0.404; p = 0.022). Furthermore, cTNI displayed a moderate but slightly better prognostic value than NT-pro BNP on all examined days (AUC for cTNI, d1 = 0.635; 95% CI 0.541–0.729; p = 0.007 vs. AUC for NT-pro BNP, d1 = 0.582; 95% CI 0.477–0.687; p = 0.132). In conclusion, cTNI was a reliable diagnostic parameter for the diagnosis of sepsis and septic shock, as well as a reliable prognostic tool with regard to 30-day all-cause mortality in patients suffering from sepsis and septic shock.

Abstract
"Background: NT-proB-type Natriuretic Peptide (BNP) (NT-pro BNP) is one of the biomarkers that has been studied in recent decades in connection with pediatric heart failure (HF) and congenital heart disease (CHD). Recently, infants hypothesized that serum. NT-pro BNP levels might be a good predictor of septicemia severity and response to treatment and prognosis in these patients. This study investigated the relationship between serum natriuretic type B peptide level and neonatal sepsis. Materials and Method: In this case-control study, all full-term and pre-term neonates admitted to children’s Hospital, TabrizIran(2021), with sepsis and a septicemia diagnosis were confirmed after obtaining consent. The study was deliberately entered by the patient's parents or legal guardian. Complete Blood Count with Differential (CBC/Diff ), C - reactive protein (CRP) , Bacterial Culture (B/C) , Urine Analyze(U/A),Urine Culture (U/C) ,NT-pro BNP were checked and finally compared with laboratory results of the same number of infants who did not have clinical and laboratory symptoms of sepsis. After collecting samples, laboratory results, including serum levels of NT-pro BNP, were compared in case and control groups. Results: One hundred patients were studied in two groups. Thirty-eight patients (38%) were boys, and 62 patients (62%) were girls. The mean age of the patients was 7.58±7.46 days. The mean weight of the studied patients was 2811.80±620.33 grams, with a median of 2855 grams. The most common clinical symptom observed in patients in the case group was fever (100%) followed by Poor feeding (84%). In the control group, all patients had jaundice. Neonates with sepsis had significantly higher initial pro-BNP values than the control group (10023.80 vs. 2247.20; p=0.001). The NT-pro BNP level cut-off point in predicting the final treatment status and mortality of neonates with sepsis was 9583 pg/ml with 97.7% sensitivity and 93.6% specificity. Conclusion: Measurement of serum level of NT-Pro BNP in neonates with sepsis at the time of clinical signs with 97.7% sensitivity and 93.6% specificity with a cut-off point of 9583 is an important prognostic factor in the therapeutic management of patients."

Abstract
BACKGROUND: Sepsis-induced myocardial dysfunction (SIMD) is an increasingly recognized form of transient cardiac dysfunction in sepsis patients.
AIM: The aim of the study was to evaluation of N-terminal pro brain natriuretic peptide (NT-pro BNP) as a predictor of SIMD and poor outcome in patients with sepsis or septic shock.
METHODS: Forty patients were enrolled and divided into: Group 1 with sepsis; Group 2 with septic shock. Each group was subdivided according to the presence or absence of cardiomyopathy. Echocardiography, NT-pro BNP - assay on the 1st and 2nd days of admission - were performed.
RESULTS: NT-pro BNP level was significant predictor for cardiomyopathy in all case group with 75% sensitivity, 70% specificity (cutoff level >334 pg/ml) on 1st day of admission and 65% sensitivity, and 80% specificity (cutoff level >325 pg/ml) on 2nd day. On subgroup analysis, pro-BNP had 70% sensitivity, 90% specificity; cutoff level >334 pg/ml for prediction of cardiomyopathy in sepsis group and 70% sensitivity and 80% specificity; cutoff level >357pg/ml in septic shock group. Pro-BNP on 2nd day was excellent predictor of mortality in septic shock group with 100% sensitivity and specificity; cutoff level >350 pg/ml.
CONCLUSION: N terminal pro-BNP is a good diagnostic and prognostic indicator for cardiomyopathy and mortality in septic patients.

Renin-Angiotensin-System Inhibitors Are Associated With Lower In-hospital Mortality in COVID-19 Patients Aged 80 and Older. Front Cardiovasc Med 2022; 9:916509. [PMID: 35783862 PMCID: PMC9247386 DOI: 10.3389/fcvm.2022.916509] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Accepted: 05/04/2022] [Indexed: 11/30/2022] Open
Abstract
Background Older adults are at higher risk of morbidity and mortality for coronavirus disease 2019 (COVID-19). Renin-angiotensin-system inhibitors (RASi) were found to have a neutral or protective effect against mortality in COVID-19 adult patients. Aims We investigated whether this association was confirmed also in COVID-19 older patients. Methods This is a prospective observational study on 337 hospitalized older adults (aged 80 years and older). We classified the study population according to usage of RASi before and during hospitalization. A propensity score analysis was also performed to confirm the findings. Results The mean age was 87.4 ± 6.1 years. Patients taking RASi at home were 147 (43.6%). During hospitalization, 38 patients (11.3% of the entire study population) discontinued RASi, while 57 patients (16.9% of the entire study population) started RASi. In-hospital mortality was 43.9%. Patients taking RASi during hospitalization (patients who maintained their home RASi therapy + patients who started RASi during hospitalization) had a significantly lower in-hospital mortality than untreated patients [HR 0.48 (95% CI: 0.34–0.67)], even after adjustment for required respiratory support, functional status, albumin, inflammation, and cardiac biomarkers. The analysis of the groups derived from the “propensity score matching” (58 patients in each group) confirmed these results [HR 0.46 (95% CI: 0.23–0.91)]. Discussion Despite the high risk of death in older COVID-19 patients, RASi therapy during hospitalization was associated with a clinically relevant lower in-hospital mortality, likely due to the benefit of RAS modulation on the cardiopulmonary system during the acute phase of the disease. Conclusion Our findings confirm the protective role of RASi even in COVID-19 patients aged 80 years and older.

Abstract
Introduction Severe COVID-19 constitutes a form of viral sepsis. Part of the specific pathophysiological pattern of this condition is the occurrence of cardiovascular events. These include pulmonary embolism, arrhythmias and cardiomyopathy as manifestations of extra-pulmonary organ dysfunction. Hitherto, the prognostic impact of these cardiovascular events and their predisposing risk factors remains unclear. This study aims to explore this question in two cohorts of viral sepsis–COVID-19 and influenza–in order to identify new theragnostic strategies to improve the short- and long-term outcome of these two diseases. Methods and analysis In this prospective multi-centre cohort study, clinical assessment will take place during the acute and post-acute phase of sepsis and be complemented by molecular laboratory analyses. Specifically, echocardiography and cardiovascular risk factor documentation will be performed during the first two weeks after sepsis onset. Aside from routine haematological and biochemical laboratory tests, molecular phenotyping will comprise analyses of the metabolome, lipidome and immune status. The primary endpoint of this study is the difference in 3-month mortality of patients with and without septic cardiomyopathy in COVID-19 sepsis. Patients will be followed up until 6 months after onset of sepsis via telephone interviews and questionnaires. The results will be compared with a cohort of patients with influenza sepsis as well as previous cohorts of patients with bacterial sepsis and healthy controls. Ethics and dissemination Approval was obtained from the Ethics Committee of the Friedrich Schiller University Jena (2020-2052-BO). The results will be published in peer-reviewed journals and presented at appropriate conferences. Trial registration DRKS00024162.

Abstract
Sepsis remains a worldwide challenge for physicians with many patients admitted to ICUs with septic shock. Septic shock management involves targeted treatment to control infections, reduce end-organ damage, and reverse the injury. Sepsis-induced myocardial dysfunction or septic cardiomyopathy remains an avenue to be explored with regard to underlying pathophysiology and definite treatment guidelines. This article has compiled various studies to explain the possible mechanisms involved in the development of septic cardiomyopathy and the existing diagnostic criteria including radiological and laboratory tests to assess septic cardiomyopathy. Furthermore, the article highlights management options currently available for physicians dealing with myocardial dysfunction secondary to sepsis.

Abstract
Determination of specific cardiac biomarkers (CBs) during the diagnosis and management of adverse cardiovascular events such as acute myocardial infarction (AMI) has become commonplace in emergency department (ED), cardiology and many other ward settings. Cardiac troponins (cTnT and cTnI) and natriuretic peptides (BNP and NT-pro-BNP) are the preferred biomarkers in clinical practice for the diagnostic workup of AMI, acute coronary syndrome (ACS) and other types of myocardial ischaemia and heart failure (HF), while the roles and possible clinical applications of several other potential biomarkers continue to be evaluated and are the subject of several comprehensive reviews. The requirement for rapid, repeated testing of a small number of CBs in ED and cardiology patients has led to the development of point-of-care (PoC) technology to circumvent the need for remote and lengthy testing procedures in the hospital pathology laboratories. Electroanalytical sensing platforms have the potential to meet these requirements. This review aims firstly to reflect on the potential benefits of rapid CB testing in critically ill patients, a very distinct cohort of patients with deranged baseline levels of CBs. We summarise their source and clinical relevance and are the first to report the required analytical ranges for such technology to be of value in this patient cohort. Secondly, we review the current electrochemical approaches, including its sub-variants such as photoelectrochemical and electrochemiluminescence, for the determination of important CBs highlighting the various strategies used, namely the use of micro- and nanomaterials, to maximise the sensitivities and selectivities of such approaches. Finally, we consider the challenges that must be overcome to allow for the commercialisation of this technology and transition into intensive care medicine.

Abstract
It is not uncommon for the forensic pathologist to question whether a deceased person had experienced sepsis that could have either been the cause of or contributed to the person's death. Often, the missing typical pathologic factors or lack of clinical and circumstantial information on the death render the autopsy of a sepsis-related death a difficult task for the forensic pathologist. Several authors emphasize on how an immunohistochemical analysis could help in diagnosing death related to sepsis. The research we carried out analyzes the main scientific studies in the literature, primarily the tracing of 21 immunohistochemical antigens evaluated to help diagnose death related to sepsis. The purpose of this review was to analyze and summarize the markers studied until now and to consider the limitations of immunohistochemistry that currently exist with regard to this particular field of forensic pathology. Immunohistochemistry provided interesting and promising results, but further studies are needed in order for them to be confirmed, so that they may be applied in standard forensic practice.

Abstract
Background Serum lactate, troponin, and N-terminal pro-B-type natriuretic peptide (NT-proBNP) have been proposed to be useful prognostic indicators in patients with sepsis and septic shock. This study aimed to evaluate the predictive ability of these biomarkers and assess how their prognostic utility may be improved by using them in combination. Material/Methods A retrospective review of the medical records of 1242 patients with sepsis and septic shock who were admitted to the Richmond University Medical Center between June 1, 2018, and June 1, 2019, was carried out; 427 patients met the study criteria and were included in the study. The primary outcome measures included 30-day mortality, APACHE II scores, length of hospital stay, and admission to the Medical Intensive Care Unit (MICU). Results High levels of lactate (>4 mmol/L), troponin (>0.45 ng/mL), and NT-proBNP (>8000 pg/mL) were independent predictors of 30-day mortality, with an adjusted odds ratio of mortality being 3.19 times, 2.13 times, and 2.5 times higher, respectively, compared with corresponding reference groups, at 95% confidence intervals. Elevated levels of lactate, troponin, and NT-proBNP were associated with 9.12 points, 7.70 points, and 8.88 points in higher APACHE II scores, respectively. Only elevated troponin levels were predictive of a longer length of hospital stay. In contrast, elevated lactate and troponin were associated with an increased chance of admission to the MICU. Conclusions Elevated levels of serum lactate, troponin, and NT-proBNP are independent predictors of mortality and higher APACHE II scores in patients with sepsis and septic shock.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) has been reported to cause worse outcomes in patients with underlying cardiovascular disease, especially in patients with acute cardiac injury, which is determined by elevated levels of high-sensitivity troponin. There is a paucity of data on the impact of congestive heart failure (CHF) on outcomes in COVID-19 patients. METHODS We conducted a literature search of PubMed/Medline, EMBASE, and Google Scholar databases from 11/1/2019 till 06/07/2020, and identified all relevant studies reporting cardiovascular comorbidities, cardiac biomarkers, disease severity, and survival. Pooled data from the selected studies was used for metanalysis to identify the impact of risk factors and cardiac biomarker elevation on disease severity and/or mortality. RESULTS We collected pooled data on 5967 COVID-19 patients from 20 individual studies. We found that both non-survivors and those with severe disease had an increased risk of acute cardiac injury and cardiac arrhythmias, our pooled relative risk (RR) was - 8.52 (95% CI 3.63-19.98) (p < 0.001); and 3.61 (95% CI 2.03-6.43) (p = 0.001), respectively. Mean difference in the levels of Troponin-I, CK-MB, and NT-proBNP was higher in deceased and severely infected patients. The RR of in-hospital mortality was 2.35 (95% CI 1.18-4.70) (p = 0.022) and 1.52 (95% CI 1.12-2.05) (p = 0.008) among patients who had pre-existing CHF and hypertension, respectively. CONCLUSION Cardiac involvement in COVID-19 infection appears to significantly adversely impact patient prognosis and survival. Pre-existence of CHF, and high cardiac biomarkers like NT-pro BNP and CK-MB levels in COVID-19 patients correlates with worse outcomes.

Abstract
BACKGROUND Risk stratification is important for the management of community-acquired pneumonia (CAP). The present study aimed to investigate the clinical impact of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) on prognosis and to identify clinical characteristics associated with NT-proBNP elevation in CAP patients. METHODS This retrospective study included patients hospitalized for CAP at a tertiary referral center and who underwent measurement plasma NT-proBNP levels. Based on 30-day mortality, patients (n = 1,821) were divided into 2 groups, survivors (n = 150) and nonsurvivors (n = 1,671), and clinical and laboratory findings were compared. RESULTS In multivariate analysis, blood levels of NT-proBNP (>942.5 pg/mL), albumin (<3.3 g/dL), and troponin I (>0.018 ng/mL) independently predicted 30-day mortality. Of these blood biomarkers, NT-proBNP exhibited the highest C-statistic, followed by albumin. NT-proBNP level/CURB-65 score and NT-proBNP level/pneumonia severity index (PSI) class exhibited significantly higher C-statistics than CURB-65 score and PSI class alone, respectively. The 3-test combinations of CURB-65 score/NT-proBNP level/albumin level and PSI class/NT-proBNP level/albumin level exhibited significantly higher C-statistics than the 2-test combinations. NT-proBNP elevation was associated with increased age, heart disease and chronic kidney disease and NT-proBNP levels only weakly or moderately correlated with other blood biomarkers. CONCLUSIONS NT-proBNP level was a useful marker for the prediction of 30-day mortality in patients hospitalized with CAP, and provided additional prognostic value to PSI or CURB-65 alone.

Abstract
OBJECTIVES This systematic review and meta-analysis aimed to assess the association between N-terminal pro-brain natriuretic peptide (NT-proBNP) and mortality in patients with COVID-19. METHODS Systematic literature search from several electronic databases were performed. The outcome was mortality (non-survivor) in patients with COVID-19 pneumonia. NT-proBNP data were in continuous variable (pg/mL), dichotomous data (elevated/non-elevated) and effect estimate adjusted to cardiac injury/elevated biomarkers of cardiac injury. RESULTS A total of 967 patients from six studies were included in this analysis. NT-proBNP was higher in non-survivor group (standardised mean difference 0.75 (0.44, 1.07), p<0.001; I2: 61%). Elevated NT-proBNP was associated with increased mortality (RR 3.63 (92.21, 5.95), p<0.001; I2: 60%). Sensitivity analysis by removing a study reduces heterogeneity (risk ratio 3.47 (2.36, 5.11), p<0.001; I2: 49%). Pooled adjusted HR (adjusted to cardiac injury/elevated biomarkers of cardiac injury) showed that elevated NT-proBNP was independently associated with mortality (HR 1.37 (1.19, 1.57), p<0.001; I2: 0%, p=0.77). Pooled analysis of multiple cut-off point resulted in a sensitivity of 76% (46%-92%) and specificity of 88% (71%-96%). Summary receiver operating characteristic curve analysis demonstrates an area under curve of 0.90 (0.87-0.93). Elevated NT-proBNP has a likelihood ratio (LR) +6.4 and LR -0.3. CONCLUSION Elevated NT-proBNP level was associated with increased mortality in COVID-19 pneumonia.

Abstract
INTRODUCTION Sepsis is one of the most prevalent life-threatening conditions in the intensive care unit. Patients suffer from impaired organ function, reduced physical functional capacity and decreased quality of life even after surviving sepsis. The identification of prognostic factors for the medium-term and long-term outcomes of this condition is necessary to develop personalised theragnostic approaches. Sepsis can cause cardiac impairment. The impact of this septic cardiomyopathy on patient's long-term outcome remains unclear. This study aims to evaluate cardiovascular risk factors, particularly the occurrence of septic cardiomyopathy, regarding their suitability as prognostic factors for the short-term and long-term outcomes of septic patients. Additionally, the study seeks to validate preclinical pathophysiological findings of septic cardiomyopathy in the clinical setting. METHODS AND ANALYSIS In this prospective monocentric cohort study, patients will be clinically assessed during the acute and postacute phase of sepsis and two follow-ups after 6 and 12 months. To determine the effect of septic cardiomyopathy and concomitant cellular and molecular changes on patient mortality and morbidity, a comprehensive cardiovascular and molecular deep phenotyping of patients will be performed. This includes an echocardiographic and electrocardiographic assessment, and the evaluation of heart rate variability, body composition, mitochondrial oxygen metabolism, macrocirculation and microcirculation, and endothelial barrier function. These analyses are complemented by routine immunological, haematological and biochemical laboratory tests and analyses of the serum metabolome and lipidome, microbiome and epigenetic modifications of immune cells. The reversibility of patients' organ dysfunction, their quality of life and physical functional capacity will be investigated in the follow-ups. Patients with cardiomyopathy without infection and healthy subjects will serve as control groups. ETHICS AND DISSEMINATION Approval was obtained from the Ethics Committee of the Friedrich Schiller University Jena (5276-09/17). The results will be published in peer-reviewed journals and presented at appropriate conferences. TRIAL REGISTRATION NUMBERS DRKS00013347; NCT03620409.

Natriuretic Peptides to Predict Short-Term Mortality in Patients With Sepsis: A Systematic Review and Meta-analysis. Mayo Clin Proc Innov Qual Outcomes 2020; 4:50-64. [PMID: 32055771 PMCID: PMC7011015 DOI: 10.1016/j.mayocpiqo.2019.10.008] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Revised: 10/07/2019] [Accepted: 10/15/2019] [Indexed: 04/17/2023] Open
Abstract
Data are conflicting regarding the optimal cutoffs of B-type natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) to predict short-term mortality in patients with sepsis. We conducted a comprehensive search of several databases (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus) for English-language reports of studies evaluating adult patients with sepsis, severe sepsis, and septic shock with BNP/NT-proBNP levels and short-term mortality (intensive care unit, in-hospital, 28-day, or 30-day) published from January 1, 2000, to September 5, 2017. The average values in survivors and nonsurvivors were used to estimate the receiver operating characteristic curve (ROC) using a parametric regression model. Thirty-five observational studies (3508 patients) were included (median age, 51-75 years; 12%-74% males; cumulative mortality, 34.2%). A BNP of 622 pg/mL had the greatest discrimination for mortality (sensitivity, 0.695 [95% CI, 0.659-0.729]; specificity, 0.907 [95% CI, 0.810-1.003]; area under the ROC, 0.766 [95% CI, 0.734-0.797]). An NT-proBNP of 4000 pg/mL had the greatest discrimination for mortality (sensitivity, 0.728 [95% CI, 0.703-0.753]; specificity, 0.789 [95% CI, 0.710-0.867]; area under the ROC, 0.787 [95% CI, 0.766-0.809]). In prespecified subgroup analyses, identified BNP/NT-proBNP cutoffs had higher discrimination if specimens were obtained 24 hours or less after admission, in patients with severe sepsis/septic shock, in patients enrolled after 2010, and in studies performed in the United States and Europe. There was inconsistent adjustment for renal function. In this hypothesis-generating analysis, BNP and NT-proBNP cutoffs of 622 pg/mL and 4000 pg/mL optimally predicted short-term mortality in patients with sepsis. The applicability of these results is limited by the heterogeneity of included patient populations.

Abstract
Background: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a useful cardiac biomarker that is associated with acute kidney injury (AKI) and mortality after cardiac surgery. However, its prognostic value in cardiac surgical patients receiving renal replacement therapy (RRT) remains unclear. Objectives: Our study aimed to assess the prognostic value of NT-proBNP in patients with established AKI receiving RRT after cardiac surgery. Methods: A total of 163 cardiac surgical patients with AKI requiring RRT were enrolled in this study. Baseline characteristics, hemodynamic variables at RRT initiation, and NT-proBNP level before surgery, at RRT initiation, and on the first day after RRT were collected. The primary outcome was 28-day mortality after RRT initiation. Results: Serum NT-proBNP levels in non-survivors was markedly higher than survivors before surgery (median: 4,096 [IQR, 962.0-9583.8] vs. 1,339 [IQR, 446-5,173] pg/mL; P < 0.01), at RRT initiation (median: 10,366 [IQR, 5,668-20,646] vs. 3,779 [IQR, 1,799-11,256] pg/mL; P < 0.001), and on the first day after RRT (median: 9,055.0 [IQR, 4,392-24,348] vs. 5,255 [IQR, 2,134-9,175] pg/mL; P < 0.001). The area under the receiver operating characteristic curve of NT-proBNP before surgery, at RRT initiation, and on the first day after RRT for predicting 28-day mortality was 0.64 (95% CI, 0.55-0.73), 0.71 (95% CI, 0.63-0.79), and 0.68 (95% CI, 0.60-0.76), respectively. Consistently, Cox regression revealed that NT-proBNP levels before surgery (HR: 1.27, 95% CI, 1.06-1.52), at RRT initiation (HR: 1.11, 95% CI, 1.06-1.17), and on the first day after RRT (HR: 1.17, 95% CI, 1.11-1.23) were independently associated with 28-day mortality. Conclusions: Serum NT-proBNP was an independent predictor of 28-day mortality in cardiac surgical patients with AKI requiring RRT. The prognostic role of NT-proBNP needs to be confirmed in the future.

Abstract
Sepsis continues to be a leading public health burden in the United States and worldwide. With the increasing use of advanced laboratory technology, there is a renewed interest in the use of biomarkers in sepsis to aid in more precise and targeted decision-making. Natriuretic peptides have been increasingly recognized to play a role outside of heart failure. They are commonly elevated among critically ill patients in the setting of cardiopulmonary dysfunction and may play a role in identifying patients with sepsis and septic shock. There are limited data on the role of these biomarkers in the diagnosis, management, outcomes and prognosis of septic patients. This review seeks to describe the role of natriuretic peptides in fluid resuscitation, diagnosis of ventricular dysfunction and outcomes and the prognosis of patients with sepsis. B-type natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP) have been noted to be associated with left ventricular systolic and diastolic and right ventricular dysfunction in patients with septic cardiomyopathy. BNP/NT-proBNP may predict fluid responsiveness, and trends of these peptides may play a role in fluid resuscitation. Despite suggestions of a correlation with mortality, the role of BNP in mortality outcomes and prognosis during sepsis needs further evaluation.

Abstract
INTRODUCTION We hypothesized that aromatic microbial metabolites (AMM), such as phenyllactic (PhLA), p-hydroxyphenylacetic (p-HPhAA), and p-hydroxyphenyllactic (p-HPhLA) acids, contribute to the pathogenesis of septic shock. METHODS Clinical and laboratory data of patients with community-acquired pneumonia were obtained on intensive care unit admission and the next day. Patients were divided into two groups based on septic shock presence or absence. The levels of AMM (PhLA, p-HPhAA, p-HPhLA, and their sum, ∑3AMM), catecholamine metabolites (3,4-dihydroxymandelic [DHMA], 3,4-dihydroxyphenylacetic [DOPAC], and homovanillic [HVA] acids), lactate, N-terminal pro-brain natriuretic peptide (NT-proBNP), inducible nitric oxide synthase (iNOS), and procalcitonin (PCT) were compared. Correlations between AMM and clinical and laboratory data were calculated. RESULTS There were 20 patients in the septic shock group and 21 in the nonseptic shock group. On admission, the septic shock patients demonstrated significantly higher levels of PhLA (2.3 vs. 0.8 μmol/L), p-HPhAA (4.6 vs. 1.4 μmol/L), p-HPhLA (7.4 vs. 2.6 μmol/L), HVA, lactate, and significantly lower levels of iNOS. The next day, the two groups also showed significant differences in the levels of PCT and NT-proBNP. The correlation between ∑3AMM and presence of shock, levels of lactate, HVA, and NT-proBNP on admission was 0.44, 0.67, 0.57, and 0.38, respectively, and the correlation on the next day was 0.59, 0.73, 0.76, and 0.6, respectively (P < 0.01). These findings can be explained by the ability of AMM to reduce tyrosine hydroxylase activity, thus limiting the synthesis of catecholamines. CONCLUSIONS AMM are involved in the pathogenesis of septic shock.

Prognostic value of NT-proBNP levels in the acute phase of sepsis on lower long-term physical function and muscle strength in sepsis survivors. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2019; 23:230.

Abstract
Background Sepsis survivors often develop chronic critical illness (CCI) and demonstrate the persistent inflammation, immunosuppression, and catabolism syndrome predisposing them to long-term functional limitations and higher mortality. There is a need to identify biomarkers that can predict long-term worsening of physical function to be able to act early and prevent mobility loss. N-terminal pro-brain natriuretic peptide (NT-proBNP) is a well-accepted biomarker of cardiac overload, but it has also been shown to be associated with long-term physical function decline. We explored whether NT-proBNP blood levels in the acute phase of sepsis are associated with physical function and muscle strength impairment at 6 and 12 months after sepsis onset. Methods This is a retrospective analysis conducted in 196 sepsis patients (aged 18–86 years old) as part of the University of Florida (UF) Sepsis and Critical Illness Research Center (SCIRC) who consented to participate in the 12-month follow-up study. NT-proBNP was measured at 24 h after sepsis onset. Patients were followed to determine physical function by short physical performance battery (SPPB) test score (scale 0 to12—higher score corresponds with better physical function) and upper limb muscle strength by hand grip strength test (kilograms) at 6 and 12 months. We used a multivariate linear regression model to test an association between NT-proBNP levels, SPPB, and hand grip strength scores. Missing follow-up data or absence due to death was accounted for by using inverse probability weighting based on concurrent health performance status scores. Statistical significance was set at p ≤ 0.05. Results After adjusting for covariates (age, gender, race, Charlson comorbidity index, APACHE II score, and presence of CCI condition), higher levels of NT-proBNP at 24 h after sepsis onset were associated with lower SPPB scores at 12 months (p < 0.05) and lower hand grip strength at 6-month (p < 0.001) and 12-month follow-up (p < 0.05). Conclusions NT-proBNP levels during the acute phase of sepsis may be a useful indicator of higher risk of long-term impairments in physical function and muscle strength in sepsis survivors.

Abstract
BACKGROUND Diagnosing non-acute heart failure (HF) remains challenging, notably in the early stages of the syndrome. The diagnostic value of mid-regional pro-atrial natriuretic peptide (MR-proANP) has been proven in acute onset HF, but its role in early non-acute HF is unknown. We aimed to determine the diagnostic value of MR-proANP in suspected non-acute HF. METHODS AND RESULTS In total, 721 people suspected of non-acute HF in primary care underwent standardised diagnostic work-up including chest X-ray, electrocardiogram, N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurement and echocardiography. Of these, 245 people underwent additional MR-proANP measurements. The outcome of HF was assessed by an expert panel comprised of two cardiologists and one expert physician, who used all available diagnostic information including echocardiography, but were blinded to biomarker results. Of the 245 people (mean age 71.0 years, 62.9% female), 72 (29.4%) were diagnosed with HF. The c-statistics of MR-proANP and NT-proBNP as single diagnostic test were 0.77 [95% confidence interval (CI) 0.70-0.84] and 0.79 (95% CI 0.73-0.86), respectively. The cut-point with the highest accuracy for MR-proANP was 120 pmol/L [sensitivity/specificity/positive predictive value (PPV)/negative predictive value (NPV) 0.72, 0.69, 0.46, and 0.86, respectively], and the best exclusionary cut-point was 40 pmol/L (sensitivity/specificity/PPV/NPV 0.99, 0.06, 0.30, and 0.92, respectively). After addition of MR-proANP on top of a previously validated clinical model, the c-statistic rose from 0.82 (95% CI 0.76-0.88) to 0.86 (95% CI 0.80-0.92), and with the addition of NT-proBNP to 0.87 (95% CI 0.81-0.92). No sex interactions between the biomarkers and HF were found in the multivariable models. CONCLUSION MR-proANP provides added diagnostic value in suspected non-acute HF, similar to NT-proBNP.

Abstract
Pneumonia is the leading infectious cause of mortality worldwide and one of the most common lower respiratory tract infections that is contributing significantly to the burden of antibiotic consumption. Due to the complexity of its pathophysiology, it is widely accepted that clinical diagnosis and prognosis are inadequate for the accurate assessment of the severity of the disease. The most challenging task for a physician is the risk stratification of patients with community-acquired pneumonia. Herein, early diagnosis is essential in order to reduce hospitalization and mortality. Procalcitonin and C-reactive protein remain the most widely used biomarkers, while interleukin 6 has been of particular interest in the literature. However, none of them appear to be ideal, and the search for novel biomarkers that will most sufficiently predict the severity and treatment response in pneumonia has lately intensified. Although our insight has significantly increased over the last years, a translational approach with the application of genomics, metabolomics, microbiomics, and proteomics is required to better understand the disease. In this review, we discuss this rapidly evolving area and summarize the application of novel biomarkers that appear to be promising for the accurate diagnosis and risk stratification of pneumonia.

Abstract
Echocardiography and cardiac biomarkers, such as cardiac troponin I (cTnI) and N-terminal pro-B-type natriuretic peptide (NT-pro BNP) are useful tools to evaluate cardiac dysfunction. Left ventricular systolic dysfunction (LVSD) is common in pediatric severe sepsis. The aim of this study is to evaluate the prognostic value of LVSD, cTnI, and NT-pro BNP for pediatric severe sepsis.A prospective, single center, observational study was conducted. Severe sepsis children were enrolled in the study from December 2015 to December 2016 in pediatric intensive care unit of Shanghai Children's Medical Center. Recorded general information, transthoracic echocardiography were performed at day 1, 2, 3, 7, and 10, using Simpson to measure left ventricular end-diastolic dimension and left ventricular end-systolic dimension, obtained echocardiography parameters: left ventricular ejection fraction (LVEF), left ventricular fractional shortening, left ventricular end-diastolic volume, left ventricular end- systolic volume, stroke volume, cardiac output. At the same time collecting the blood sample to measure cTnI, NT-pro BNP. The definition of LVSD was LVEF <50%. According to the prognosis of 28 days, children with severe sepsis were divided into survived group and nonsurvived group.Total of 50 pediatric patients who were diagnosed with severe sepsis (including septic shock) were enrolled, the incidence of LVSD was 52%. The 28-day mortality rate of severe sepsis was 34%. Multivariate logistic regression analyses for predictors of death in pediatric severe sepsis revealed that the 28-day mortality of severe sepsis was associated with mechanical ventilation (MV) within the first 6 hours of admission (odds ratio [OR], 0.01; 95% confidence interval [CI], 0.00-0.07) and total MV time (OR, 0.81; 95% CI, 0.68-0.97). The receiver operating characteristic curves LVEF (area under curve = 0.526), cTnI (area under curve = 0.480), and NT-pro BNP (area under curve = 0.624) were used to predict the 28-day mortality in pediatric severe sepsis. Follow-up echocardiography parameters for survived group and nonsurvived group showed no significant changes in LVEF, LVFS, stroke volume index, cardiac index (CI), left ventricular end-diastolic volume index and left ventricular end-systolic volume index at day 1, 2, 3, 7, and 10, except for CI at day 1 and 2. Kaplan-Meier plot of 28-day mortality and LVSD in pediatric severe sepsis showed there were no statistical differences (χ = 0.042, P = .837).LVSD occurs frequently in pediatric with severe sepsis. The 28-day mortality rate of severe sepsis was also high. In this study, none of LVSD, cTnI, and NT-proBNP was associated with the prognosis of pediatric severe sepsis.

Abstract
Background The prognostic value of amino terminal pro-brain natriuretic peptide levels in patients with acute exacerbation of chronic obstructive pulmonary disease has not been fully established. Aims To investigate the predictive value of amino terminal pro-brain natriuretic peptide levels in terms of mortality, need for noninvasive mechanical ventilation, invasive mechanical ventilation, and weaning success. Study Design Cohort study. Methods Patients who were admitted to intensive care unit between December 2015 and December 2016 due to acute exacerbation of chronic obstructive pulmonary disease were included in the study. Demographic data, noninvasive mechanical ventilation application, need for invasive mechanical ventilation, amino terminal pro-brain natriuretic peptide level, duration of mechanical ventilation, intensive care unit and hospital stay, weaning success, and mortality rates were recorded. Results A total of 110 patients (75 males) were included in the study. The mean age of the participants was 69 (61-76) years, and the mean Acute Physiology and Chronic Health Evaluation II score was 19 (15-23). The mean amino terminal pro-brain natriuretic peptide level was found to be lower in cases with noninvasive mechanical ventilation success than those with noninvasive mechanical ventilation failure (p=0.053). In addition, the mean amino terminal pro-brain natriuretic peptide level was significantly higher (4740 pg/mL vs. 3004 pg/mL, p=0.001) in patients who needed invasive mechanical ventilation support than in patients who did not. The mortality rate was significantly higher in patients who had an increasing trend of amino terminal pro-brain natriuretic peptide levels during hospitalization than in patients who had decreasing levels (59% vs. 23%, p=0.015). Based on the receiver operating characteristic analysis, the increasing trend of amino terminal pro-brain natriuretic peptide levels during intensive care unit stay predicted mortality with area under curve of 0.84 (p<0.0001, 95% CI: 0.75-0.93) and predicted invasive mechanical ventilation need with area under curve of 0.68. Conclusion In cases of acute exacerbation of chronic obstructive pulmonary disease requiring mechanical ventilation, amino terminal pro-brain natriuretic peptide measurement and monitoring of its trend may be a valuable asset in predicting mortality, noninvasive mechanical ventilation, weaning success, and need for invasive mechanical ventilation.

Expanded A-DROP Score: A New Scoring System for the Prediction of Mortality in Hospitalized Patients with Community-acquired Pneumonia. Sci Rep 2018; 8:14588.

Abstract
There are several established prognostic scoring systems for community-acquired pneumonia (CAP). The Pneumonia Severity Index (PSI) is a prediction rule consisting of 20 variables to identify low-risk patients with CAP. Although PSI had high discrimination ability, it is complex to calculate and difficult to use in busy hospital settings. The CURB-65 score is much simpler to use than is PSI, but it has lower sensitivity for predicting mortality compared with PSI. The A-DROP score is a modified version of the CURB-65 score and provides similar predictive power to that of CURB-65. This study was performed to determine whether a simpler score (CURB-65, A-DROP), expanded with a small number of additional variables, can predict mortality more accurately than PSI. We conducted a retrospective observational study of 1,031 patients with CAP who were hospitalized at a tertiary teaching hospital. We used age, sex, comorbidities, vital signs, and laboratory findings as prognostic variables. We compared the PSI, CURB-65, and A-DROP scores using receiver operating characteristic curve analysis. The areas under the curves (AUCs) of PSI, CURB-65, and A-DROP were 0.735, 0.701, and 0.730, respectively.Multivariable analysis identified malignancy [odds ratio (OR): 2.17, 95% confidence interval (CI): 1.13–4.17], respiration rate ≥ 24/min [OR: 2.18, 95% CI: 1.24–3.82], heart rate ≥ 100/min [OR: 2.92, 95% CI: 1.68–5.08], albumin ≤ 3.09 g/dL [OR: 3.85, 95% CI: 2.09–7.07], lactate > 1.7 mmol/L [OR: 2.59, 95% CI: 1.53–4.38], and N-terminal prohormone brain natriuretic peptide > 500 pg/mL [OR: 2.23, 95% CI: 1.26–3.95] as prognostic factors. Using the prognostic variables identified in the multivariable analysis, we assembled a new scoring system, the expanded A-DROP score. The AUC of this score for the prediction of 28-day mortality was 0.834 (95% CI: 0.794–0.874). Bootstrap validation yielded an estimated AUC of 0.833, indicating negligible overfitting of the model.The expanded A-DROP score is a relatively simple and effective scoring system, and its predictive value was superior to those of other scoring systems.

Abstract
BackgroundTo validate the findings of a single-center pilot study showing elevated urinary N-terminal B-type natriuretic peptide (NTproBNP) concentrations in preterm infants subsequently developing severe retinopathy of prematurity (ROP) in a multicenter setting across eight European and Middle East countries.MethodsProspective observational study in 967 preterm infants <30 weeks' gestational age assessing the capacity of urinary NTproBNP on days of life (DOLs) 14 and 28 to predict ROP requiring treatment.ResultsUrinary NTproBNP concentrations were markedly elevated in infants who developed ROP requiring treatment (n=94) compared with survivors without ROP treatment (n=837), at both time points (median (interquartile range) DOL14: 8,950 (1,925-23,783) vs. 3,083 (1,193-17,393) vs. 816 (290-3,078) pg/ml, P<0.001) and DOL28 (2,203 (611-4,063) vs. 1,671 (254-11,340) vs. 408 (162-1,126) pg/ml, P<0.001). C-statistic of NTproBNP for treated ROP or death was 0.731 (95% confidence interval 0.654-0.774) for DOL14 and 0.683 (0.622-0.745) for DOL28 (P<0.001). Threshold scores were calculated, potentially enabling around 20% of infants with low NTproBNP scores never to be screened with ophthalmoscopy.ConclusionThere is a strong association between early urinary NTproBNP and subsequent ROP development, which can be used to further refine subgroups of patients with high or low risk of severe ROP.

Abstract
INTRODUCTION The aim of this study is to compare the prognostic value of N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in septic and non-septic intensive care patients. MATERIAL AND METHODS Fifty consecutive patients admitted to the intensive care unit (ICU) were enrolled in either the septic or non-septic group according to the criteria in the International Sepsis Definitions Conference in 2001. Demographic and clinical data, procalcitonin and lactate levels at admission, and death within 28 days were registered. Five blood samples were collected from all patients for NT-proBNP measurements. RESULTS Septic patients had higher APACHE II (19 (16.00-24.25) vs. 16 (13.00-18.25)), and SOFA (8 (5-10) vs. 6 (4-7)) scores (p <0.05). Procalcitonin levels were also higher in septic patients (3.33 (1.06-10.96) vs. 0.46 (0.26-1.01) ng/ml) and more patients required vasopressors in this group (9 (36%) vs. 2 (8%)) (p < 0.05). In the septic group, the correlation between mortality and the level of NT-proBNP was significant for each measurement, starting from the admission. In the non-septic group the correlation between mortality and the level of NT-proBNP was significant only at the 120th h. CONCLUSIONS We concluded that the level of NT-proBNP at admission is well correlated with 28-day mortality in septic ICU patients. However, single measurement of NT-proBNP levels in non-septic patients does not correlate with the 28-day mortality. Repeated measurements and an increasing trend of the NT-proBNP levels may show a correlation with mortality in non-septic intensive care patients.

Abstract
BACKGROUND Cardiac troponin I levels are often obtained to help rule out acute coronary syndrome. OBJECTIVE To determine if elevation of troponin level within 24 hours for patients without acute coronary syndrome admitted to the intensive care unit provides important prognostic information. METHODS Patients without acute coronary syndrome admitted to the intensive care unit were prospectively divided into 2 groups according to highest serum level of cardiac troponin I within 24 hours of admission (elevated > 0.049 ng/mL; control ≤ 0.049 ng/mL). Hospital mortality, incidence of intubation, and other parameters were compared between the 2 groups. RESULTS Patients with elevated troponin level (n = 40) had higher mortality than did control patients (n = 50) (35% vs 12%; P= .01). Compared with control patients, patients with elevated levels were more likely to be intubated (41% vs 17%; P= .02). CONCLUSION Critically ill patients without acute coronary syndrome with elevated levels of cardiac troponin I at admission had higher mortality and more intubations than did control patients.

Abstract
B-type natriuretic peptide (BNP) has diagnostic, therapeutic, and prognostic utility in critically ill patients. For severe sepsis and septic shock patients in particular, similar clinical utility from the most proximal aspects of hospital presentation to the intensive care unit has not been examined. BNP levels were measured at 0, 3, 6, 12, 24, 36, 48, 60, and 72 hours in 252 patients presenting to the emergency department with severe sepsis and septic shock. The clinicians were blinded to the BNP levels. Elevated BNP levels (>100 pg/mL) were seen in 42% and 69% of patients on presentation and at 24 hours, respectively. Elevated BNP ranges (>230 pg/mL) were significantly associated with myocardial dysfunction and severity of global tissue hypoxia. When adjusted for age, gender, history of heart failure, renal function, organ dysfunction, and mean arterial pressure, a BNP greater than 210 pg/mL at 24 hours was the most significant independent indicator of increased mortality: odds ratio 1.061 (1.026-1.097), P < .001, 95% confidence interval. Patients with severe sepsis and septic shock often have elevated BNP levels, which are significantly associated with organ and myocardial dysfunction, global tissue hypoxia, and mortality. Serial BNP levels may be a useful adjunct in the early detection, stratification, treatment, and prognostication of high-risk patients.

Abstract
BACKGROUND Timely decision making in Intensive Care Unit (ICU) is very essential to improve the outcome of critically sick patients. Conventional scores like Acute Physiology and Chronic Health Evaluation (APACHE IV) are quite cumbersome with calculations and take minimum 24 hours. Procalcitonin has shown to have prognostic value in ICU/Emergency department (ED) in disease states like pneumonia, sepsis etc. NTproBNP has demonstrated excellent diagnostic and prognostic importance in cardiac diseases. It has also been found elevated in non-cardiac diseases. We chose to study the prognostic utility of these markers on ICU admission. SETTINGS AND DESIGN Retrospective observational study. MATERIALS AND METHODS A Retrospective analysis of 100 eligible patients was done who had undergone PCT and NTproBNP measurements on ICU admission. Their correlations with all cause mortality, length of hospital stay, need for ventilator support, need for vasopressors were performed. RESULTS Among 100 randomly selected ICU patients, 28 were non-survivors. NTproBNP values on admission significantly correlated with all cause mortality (P = 0.036, AUC = 0.643) and morbidity (P = 0.000, AUC = 0.763), comparable to that of APACHE-IV score. PCT values on admission did not show significant association with mortality, but correlated well with morbidity and prolonged hospital length of stay (AUC = 0.616, P = 0.045). CONCLUSION The current study demonstrated a good predictive value of NTproBNP, in terms of mortality and morbidity comparable to that of APACHE-IV score. Procalcitonin, however, was found to have doubtful prognostic importance. These findings need to be confirmed in a prospective larger study.

Abstract
In the present study, the levels of NT-proBNP, troponin T, and troponin I were measured in postmortem serum from femoral blood in a series of sepsis-related fatalities that had undergone forensic autopsies. We aimed to assess whether a possible increase in the concentrations of these biomarkers was correlated to macroscopic or microscopic observations that suggest myocardial damage or cardiac dysfunction. Two study groups were retrospectively formed, a sepsis-related fatalities group and a control group. Both groups consisted of 16 forensic autopsy cases. Unenhanced computed tomography scan, autopsy, histological, toxicological, microbiological, and biochemical analyses were performed for all cases in both groups. Levels of procalcitonin, C-reactive protein, NT-proBNP, troponin T, and troponin I were systematically measured in postmortem serum from femoral blood. The preliminary results suggest that the postmortem serum troponin I, troponin T, and NT-proBNP levels are increased in sepsis-related deaths in the absence of any relevant coronary artery disease, myocardial ischemia, or signs of heart failure. These findings corroborate clinical data from previous studies pertaining to the usefulness of troponins and natriuretic peptides as indicators of toxic and inflammatory damage to the heart in cases of severe sepsis and septic shock without concomitant underlying coronary syndromes.

Abstract
Cardiovascular disease continues to be the leading cause of global morbidity and mortality. Traditional risk factors account for only part of the attributable risk. The origins of atherosclerosis are in early life, a potential albeit largely unrecognized window of opportunity for early detection and treatment of subclinical cardiovascular disease. There are robust epidemiological data indicating that poor intrauterine growth and/or prematurity, and perinatal factors such as maternal hypercholesterolaemia, smoking, diabetes and obesity, are associated with adverse cardiovascular intermediate phenotypes in childhood and adulthood. Many of these early-life risk factors result in a heightened inflammatory state. Inflammation is a central mechanism in the development of atherosclerosis and cardiovascular disease, but few studies have investigated the role of overt perinatal infection and inflammation (chorioamnionitis) as a potential contributor to cardiovascular risk. Limited evidence from human and experimental models suggests an association between chorioamnionitis and cardiac and vascular dysfunction. Early life inflammatory events may be an important mechanism in the early development of cardiovascular risk and may provide insights into the associations between perinatal factors and adult cardiovascular disease. This review aims to summarise current data on the early life origins of atherosclerosis and cardiovascular disease, with particular focus on perinatal inflammation.

Abstract
Timely diagnosis of bacterial infective endocarditis (IE) is crucial, as mortality remains high in this severe bacterial infection, currently without any distinct biological markers. Our goal was to evaluate potential diagnostic biomarkers by reviewing current literature. The MEDLINE, Embase and Scopus databases were searched for articles published from 1980 through June 2015 restricted to English, Norwegian, Danish and Swedish. Eighteen studies qualified, providing a review of the most promising candidates for future studies. Several studies are inconclusive, since they are characterized by using improper control groups. Patients with IE have bacteremia, and control groups should therefore be patients with bacteremia without IE. Based on current research, N-terminal-pro-B-type natriuretic peptide (NT-proBNP) alone or in combination with Cystatin C (Cys C), lipopolysaccharide-binding protein (LBP), troponins, aquaporin-9 (AQP9), S100 calcium binding protein A11 (S100A11), E-selectin (CD62E) and VCAM-1 (CD54) and interleukin-6 (IL-6) are potential biomarkers for future studies.

Abstract
Critically ill patients who display a systemic inflammatory response syndrome (SIRS) are prone to develop nosocomial infections. The challenge remains to distinguish as early as possible among SIRS patients those who are developing sepsis. Following a sterile insult, damage-associated molecular patterns (DAMPs) released by damaged tissues and necrotic cells initiate an inflammatory response close to that observed during sepsis. During sepsis, pathogen-associated molecular patterns (PAMPs) trigger the release of host mediators involved in innate immunity and inflammation through identical receptors as DAMPs. In both clinical settings, a compensatory anti-inflammatory response syndrome (CARS) is concomitantly initiated. The exacerbated production of pro- or anti-inflammatory mediators allows their detection in biological fluids and particularly within the bloodstream. Some of these mediators can be used as biomarkers to decipher among the patients those who developed sepsis, and eventually they can be used as prognosis markers. In addition to plasma biomarkers, the analysis of some surface markers on circulating leukocytes or the study of mRNA and miRNA can be helpful. While there is no magic marker, a combination of few biomarkers might offer a high accuracy for diagnosis.

Abstract
BACKGROUND Although pneumonia severity index (PSI) is widely used to evaluate the severity of community-acquired pneumonia (CAP), the calculation of PSI is very complicated. The present study aimed to evaluate the role of B-type natriuretic peptide (BNP) in predicting the severity of CAP. METHODS For 202 patients with CAP admitted to the emergency department, BNP levels, cardiac load indexes, inflammatory indexes including C-reactive protein (CRP), white blood cell count (WBC), and PSI were detected. The correlation between the indexes and PSI was investigated. BNP levels for survivor and non-survivor groups were compared, and a receiver operating characteristic (ROC) curve analysis was performed on the BNP levels versus PSI. RESULTS The BNP levels increased with CAP severity (r=0.782, P<0.001). The BNP levels of the high-risk group (PSI classes IV and V) were significantly higher than those of the low-risk group (PSI classes I-III) (P<0.001). The BNP levels were significantly higher in the non-survivor group than in the survivor group (P<0.001). In addition, there were positive correlations between BNP levels and PSI scores (r=0.782, P<0.001). The BNP level was highly accurate in predicting the severity of CAP (AUC=0.952). The optimal cut-off point of BNP level for distinguishing high-risk patients from low-risk ones was 125.0 pg/mL, with a sensitivity of 0.891 and a specificity of 0.946. Moreover, BNP level was accurate in predicting mortality (AUC=0.823). Its optimal cut-off point for predicting death was 299.0 pg/mL, with a sensitivity of 0.675 and a specificity of 0.816. Its negative predictive cut-off value was 0.926, and the positive predictive cut-off value was 0.426. CONCLUSION BNP level is positively correlated with the severity of CAP, and may be used as a biomarker for evaluating the severity of CAP.

Abstract
The prognostic value of the N-amino terminal fragment of the prohormone brain natriuretic peptide (NT-proBNP) in acute ischemic stroke (AIS) is uncertain. We sought to determine whether NT-proBNP levels were associated with functional outcomes after AIS. From August 2012 to October 2013, consecutive first-ever AIS patients admitted to the Department of Emergency of the First Affiliated Hospital of Xinxiang Medical University, China, were included in this study. Plasma NT-proBNP levels were measured from admission. Outcomes were measured as 90-day modified Rankin Scale score ('good outcome'=0-2 vs. 'poor'). Multivariate logistic regression was used to assess associations between NT-proBNP levels and outcomes. Predictive performance of NT-proBNP as compared with the clinical model was assessed by comparing receiver-operating characteristic curves. During this study period, 217 consecutive patients with AIS were included and completed 90 days of follow-up. There was a strong positive correlation between the plasma level of NT-proBNP and the National Institutes of Health Stroke Scale score (r=0.415, P=0.000). Plasma levels of NT-proBNP in patients with an unfavorable outcome were significantly higher than those in patients with a favorable outcome [3432 (interquartile range, 1100-54991) vs. 978 (interquartile range, 123-1705) pg/ml; P=0.000]. In multivariate analyses, after adjusting for all other significant outcome predictors, the NT-proBNP level that remained can be seen as an independent unfavorable outcome predictor, with an adjusted odds ratios of 4.14 (95% confidence interval, 2.72-7.99; P=0.000). Our results show that plasma NT-proBNP levels were significantly elevated in patients with an unfavorable outcome and might be of clinical importance as a supplementary tool for the assessment of functional outcomes in patients with AIS.

Abstract
INTRODUCTION The prognosis of myocardial dysfunction in critically ill patients with sepsis and its association with mortality is controversial. We aim to determine the significance of left ventricular systolic dysfunction in septic shock patients and their associated outcome. MATERIALS AND METHODS A prospective, single center, observational study was carried out at an intensive care unit of a tertiary care hospital. A total of 66 patients diagnosed with septic shock were enrolled in the study from September 2010 to June 2012. The 2D echocardiography was performed for all the patients. Ejection fraction <50% was the diagnosing parameter for the patients with systolic dysfunction in septic shock. Acute Physiology and Chronic Health Evaluation III (APACHE III) score was calculated. RESULTS The mean age of patients were found to be 53.71 ± 16.76 years. The mortality rate was found to be 48.48% and among them 43.75% patients had ejection fraction <50%. Non-survivors exhibited significantly lower mean blood pressure (74.19 ± 10.28 versus 80.59 ± 11.31; p = 0.008), lower ejection fraction (52.59 ± 16.37 versus 62.56 ± 8.31; p = 0.029) and higher APACHE III score (89.34 ± 15.41 versus 70.65 ± 13.27; p <0.001). The receiver operating characteristic curves APACHE III score (area under curve = 0.830) and ejection fraction (area under curve = 0.656) were used to predict the mortality in septic patients. CONCLUSION Low ejection fraction, a marker to measure left ventricular systolic dysfunction is a predictor of mortality in septic shock patients. However, more research is needed to confirm the findings.

Abstract
Objective This study was conducted to research the prognostic utility of N-terminal pro-B-type natriuretic peptide (NT-proBNP), compare the utility of the Seattle Heart Failure Score (SHFS) with NT-proBNP, develop a risk-evaluation model based on NT-proBNP, assess the associations of NT-proBNP with patient characteristics, and screen for decisive factors of NT-proBNP in Chinese elderly with chronic heart failure (CHF). Patients and methods There were 306 patients (≥60 years) with CHF chosen as study subjects. Each one received an assessment of NT-proBNP on serum. The end point was all-cause mortality during a mean follow-up period of 471 days. Results Subjects had a median age of 85 (60–100) years, a median NT-proBNP of 1,743.4 pg/mL, and a median SHFS of 1.87. During the follow-up period, 104 deaths occurred. NT-proBNP was significantly related to mortality (odds ratio 1.603, 95% confidence interval 1.407–1.826; P<0.001) and the significance persisted after full adjustment (odds ratio 1.282, 95% confidence interval 1.103–1.489; P=0.001). Age, New York Heart Association class IV CHF, plasma albumin, and neutrophils/lymphocytes were also independent predictors for mortality (P<0.05 for all). NT-proBNP and the SHFS showed similar predictive capacities (0.736 versus 0.796, P=0.105). The addition of NT-proBNP to the SHFS (0.818 versus 0.796, P=0.168) generated marginal growth in the c-statistic. The model based on NT-proBNP consisting of all selected predictors in this study, including age, New York Heart Association class IV CHF, plasma albumin, neutrophils/lymphocytes, and NT-proBNP, had a moderately higher c-statistic compared with the SHFS (0.846 versus 0.796, P=0.066). NT-proBNP was bound with the SHFS (r=0.500, P<0.001). Characteristics regarding general condition, inflammation, and cardiac and renal function were the decisive factors of NT-proBNP (P<0.05 for all). Conclusion As a comprehensive representation of the patient characteristics described earlier, NT-proBNP values provided significant prognostic power similar to the SHFS in Chinese elderly with CHF. A novel model based on NT-proBNP could offer help for risk stratification.

Abstract
OBJECTIVE To review the current literature in reference to the pathophysiology, diagnosis, and treatment of pyothorax in dogs and cats. ETIOLOGY Pyothorax, also known as thoracic empyema, is characterized by the accumulation of septic purulent fluid within the pleural space. While the actual route of pleural infection often remains unknown, the oral cavity and upper respiratory tract appear to be the most common source of microorganisms causing pyothorax in dogs and cats. In human medicine, pyothorax is a common clinical entity associated with bacterial pneumonia and progressive parapneumonic effusion. DIAGNOSIS Thoracic imaging can be used to support a diagnosis of pleural effusion, but cytologic examination or bacterial culture of pleural fluid are necessary for a definitive diagnosis of pyothorax. THERAPY The approach to treatment for pyothorax varies greatly in both human and veterinary medicine and remains controversial. Treatment of pyothorax has classically been divided into medical or surgical therapy and may include administration of antimicrobials, intermittent or continuous thoracic drainage, thoracic lavage, intrapleural fibrinolytic therapy, video-assisted thoracic surgery, and traditional thoracostomy. Despite all of the available options, the optimal treatment to ensure successful short- and long-term outcome, including the avoidance of recurrence, remains unknown. PROGNOSIS The prognosis for canine and feline pyothorax is variable but can be good with appropriate treatment. A review of the current veterinary literature revealed an overall reported survival rate of 83% in dogs and 62% in cats. As the clinical presentation of pyothorax in small animals is often delayed and nonspecific, rapid diagnosis and treatment are required to ensure successful outcome.

Abstract
BACKGROUNDS Using biomarkers to predict mortality in patient with severe sepsis or septic shock is of importance, as these patients frequently have high mortality and unsatisfied outcome. N-terminal pro-brain natriuretic peptide (NT-proBNP) and cardiac troponin I (cTnI) play extremely important roles in prognostic value in the mortality of severe sepsis and septic shock. AIMS The present study was retrospectively designed to evaluate the predicting mortality of NT-proBNP and cTnI in elderly patients with severe sepsis or septic shock administered in the intensive care unit (ICU) and also to evaluate whether the predicting ability of Acute Physiology and Chronic Health Evaluation II (APACHE-II) score or C-reactive protein (CRP) was increased in combination with the biomarkers. PATIENTS AND METHODS A cohort of 430 patients (aged ≥65 years) with severe sepsis or septic shock admitted to our ICU between October 2011 and December 2013 was included in the study. Patient data including clinical, laboratory, and survival and mortality were collected. All patients were examined with NT-proBNP, cTnI, CRP, and APACHE-II score and were categorized as the survived and deceased groups according to the outcome 30 days after ICU treatment. RESULTS The levels of NT-proBNP and cTnI (P < .01) or CRP (P < .05) were significantly higher in the deceased group than those in the survived group. The predicting mortality of APACHE-II score alone was low but largely improved, when it was combined with both NT-proBNP and cTnI (P < .05). CONCLUSION The alteration of NT-proBNP and cTnI levels strongly predicated the ICU prognosis in elderly patients with severe sepsis or septic shock. N-terminal pro-brain natriuretic peptide and cTnI were superior to CRP in predicting mortality. The predicting ability of APACHE-II score was improved only when combined with NT-proBNP and cTnI.

Abstract
BACKGROUND Early and accurate risk prediction is an unmet clinical need in patients with infective endocarditis (IE). The aim of this study was to determine the value of B-type natriuretic peptide (BNP) levels obtained on admission for the prediction of in-hospital death in IE patients. METHODS Between 2009 and 2011, consecutive patients with IE diagnosed using the revised Duke criteria and admitted to the emergency department were evaluated prospectively. BNP levels were measured on admission. Death during hospitalization was the primary endpoint. RESULTS Among 104 consecutive patients with IE and with available BNP levels, 34 (32.7%) died in hospital. BNP levels were significantly higher in patients who died as compared to survivors (709.0 pg/ml vs. 177.5 pg/ml, p<0.001). The accuracy of BNP to predict death as quantified by the area under the receiver operating characteristics curve was 0.826 (95% confidence interval (CI) 0.747-0.905). The value of BNP was additive to that provided by clinical, microbiological, and echocardiography assessment. On multivariate analysis, new heart failure (hazard ratio (HR) 2.02, 95% CI 1.15-3.57, p=0.015), sepsis (HR 2.10, 95% CI 1.25-3.55, p=0.005), Staphylococcus aureus endocarditis (HR 2.67, 95% CI 1.60-4.45, p<0.001), left ventricular ejection fraction ≤55% (HR 1.63, 95% CI 1.00-2.65, p=0.047), and BNP (HR 1.04, 95% CI 1.02-1.06, p<0.001) were independent predictors of in-hospital mortality. CONCLUSION Among patients with IE, BNP levels obtained on admission provide incremental value for early and accurate risk prediction.
