First-Line Immune Combination Therapies for Nonclear Cell Versus Clear Cell Metastatic Renal Cell Carcinoma: Real-World Multicenter Data From Germany

IntroductionThe aim was to compare treatment outcomes of clear cell metastatic renal cell carcinoma (ccmRCC) versus non-ccmRCC (nccmRCC) patients who received first-line immune combination therapies. Materials and MethodsWithin our retrospective multi-institutional consecutive database of eight tertiary-care centers, we identified mRCC patients treated with first-line immune combination therapies between 11/2017 and 12/2022. Using log-rank analysis and multivariable Cox regression, we tested for differences in overall survival (OS) and progression-free survival (PFS) of nccmRCC versus ccmRCC patients. Covariables consisted of age at diagnosis, sex, International Metastatic Renal Cell Carcinoma Database Consortium risk groups, Eastern Cooperative Oncology Group status, and sarcomatoid feature. ResultsOf 289 study patients, 39 (13%) patients harbored nccmRCC. Median OS was 37 months versus not reached for ccmRCC versus nccmRCC patients (P = .6). Median PFS was 13 versus 15 months (P = .9). Multivariable Cox regression models did not identify nccmRCC as an independent predictor of higher overall mortality in mRCC patients (hazard ratio [HR]: 1.23; P = .6) or a higher progression rate (HR: 1.0; P = 1.0). ConclusionIn our real-world multi-institutional study, no differences in OS and PFS between ccmRCC and nccmRCC patients receiving first-line immune combination treatment were observed, even after adjustment for important patient and tumor characteristics. More prospective trials in nccmRCC patients are needed.

Electrocardiographic abnormalities are prognostic of the clinical outcomes and mortality of patients with subarachnoid hemorrhages

PurposeWe explored the relationships between electrocardiographic (ECG) abnormalities and the clinical outcomes and mortality of patients with non-traumatic aneurysmal subarachnoid hemorrhages (SAHs). MethodsThis retrospective cohort study enrolled consecutive adult patients who presented to emergency departments with non-traumatic aneurysmal SAHs. We recorded their demographics, clinical characteristics, and ECG findings, and explored the relationships between ECG abnormalities, on the one hand, and 28-day mortality and prognosis, on the other. ResultsWe enrolled 158 patients, 76 females (48.10%) and 82 males (51.90%) of average age 54.70 ± 7.07 years. A total of 107 patients (67.72%) exhibited at least one ECG abnormality, most commonly a T-wave change (n = 54, 34.18%). Such patients evidenced significantly higher Hunt-Hess and Fisher scale scores than those without abnormalities (both p < 0.001). Patients with abnormal ECG findings experienced more unfavorable outcomes and higher mortality than others (both p < 0.001). ECG abnormalities, including PR prolongation, pathological Q waves, QRS widening, left bundle branch blocks, premature ventricular contractions, ST segment changes, and T-wave changes, were more common in non-survivors and patients with Hunt-Hess scores of 4–5 compared to survivors and those with Hunt-Hess scores <4, respectively. Moreover, increased age and presence of abnormal ECG findings were independent predictors of mortality in aneurysmal SAHs. ConclusionsPatients with abnormal ECG findings exhibited unfavorable clinical outcomes and increased mortality rates. Abnormal ECG findings combined with higher Hunt-Hess or Fischer grade scores usefully predict adverse clinical outcomes in and mortality of SAH patients.

Detectable troponin below the 99th percentile predicts survival in patients undergoing coronary angiography

BackgroundCardiac troponin I (cTnI) above the 99th percentile is associated with an increased risk of major adverse events. Patients with detectable cTnI below the 99th percentile are a heterogeneous group with a less well-defined risk profile. The purpose of this study is to investigate the prognostic relevance of detectable cTnI below the 99th percentile in patients undergoing coronary angiography. MethodsThe study included 14,776 consecutive patients (mean age of 65.4 ± 12.7 years, 71.3 % male) from the Essen Coronary Artery Disease (ECAD) registry. Patients with cTnI levels above the 99th percentile and patients with ST-segment elevation acute myocardial infarction were excluded. All-cause mortality was defined as the primary endpoint. ResultsDetectable cTnI below the 99th percentile was present in 2811 (19.0 %) patients, while 11,965 (81.0 %) patients were below detection limit of the employed assay. The mean follow-up was 4.25 ± 3.76 years. All-cause mortality was 20.8 % for patients with detectable cTnI below the 99th percentile and 15.0 % for those without detectable cTnI. In a multivariable Cox regression analysis, detectable cTnI was independently associated with all-cause mortality with a hazard ratio of 1.60 (95 % CI 1.45–1.76; p < 0.001). There was a stepwise relationship with increasing all-cause mortality and tertiles of detectable cTnI levels with hazard ratios of 1.63 (95 % CI 1.39–1.90) for the first tertile to 2.02 (95 % CI 1.74–2.35) for the third tertile. ConclusionsDetectable cTnI below the 99th percentile is an independent predictor of mortality in patients undergoing coronary angiography with the risk of death growing progressively with increasing troponin levels.

Cardiac arrest and post-discharge mortality in patients with myocardial infarction: A large-scale nationwide registry analysis

BackgroundCardiac arrest is a serious complication of acute myocardial infarction. The implementation of contemporary approaches to acute myocardial infarction management, including urgent revascularization procedures, has led to significant improvements in short-term outcomes. However, the extent of post-discharge mortality in patients experiencing cardiac arrest during acute myocardial infarction remains uncertain. This study aimed to determine the post-discharge outcomes of patients with cardiac arrest. MethodsWe analysed data from the J-PCI OUTCOME registry, a Japanese prospectively planed, observational, multicentre, national registry of percutaneous coronary intervention involving consecutive patients from 172 institutions who underwent percutaneous coronary intervention and were discharged. Patients who underwent percutaneous coronary intervention for acute myocardial infarction between January 2017 and December 2018 and survived for 30 days were included. Mortality in patients with and without cardiac arrest from 30 days to 1 year after percutaneous coronary intervention for acute myocardial infarction was compared. ResultsOf the 26,909 patients who survived for 30 days after percutaneous coronary intervention for acute myocardial infarction, 1,567 (5.8%) had cardiac arrest at the onset of acute myocardial infarction. Patients with cardiac arrest were younger and more likely to be males than patients without cardiac arrest. The 1-year all-cause mortality was significantly higher in patients with cardiac arrest than in those without (11.9% vs. 2.8%, p < 0.001) for all age groups. Multivariable analysis showed that cardiac arrest was an independent predictor of all-cause long-term mortality (hazard ratio: 2.94; 95% confidence interval: 2.29–3.76). ConclusionsPatients with acute myocardial infarction and concomitant cardiac arrest have a worse prognosis for up to 1 year after percutaneous coronary intervention than patients without cardiac arrest.

Elevated neutrophil-to-hemoglobin ratio as an indicator of poor survival in hepatitis B virus-related decompensated cirrhosis.

Aim: Our goal was to explore the prognostic value of the neutrophil-to-hemoglobin ratio (NHR) in HBV-related decompensated cirrhosis (HBV-DC) patients. Methods: 172 HBV-DC patients were enrolled. Multivariate analyses were used to identify risk factors influencing 30-day mortality. Results: The 30-day mortality was 12.8% (22/172). nonsurvivors exhibited a higher NHR than survivors. On multivariate analysis, NHR and model for end-stage liver disease (MELD) score were the only independent predictors of mortality. Notably, the predictive capabilities of NHR were found to be comparable to those of the MELD score. Conclusion: High NHR was associated with poor prognosis in HBV-DC patients, and NHR can serve as an effective and readily available indicator for the prediction of mortality in these patients.

Rhabdomyolysis, acute kidney injury, and mortality in Ebola virus disease: retrospective analysis of cases from Eastern Democratic Republic of the Congo, 2019.

Skeletal muscle injury in Ebola virus disease (EVD) has been reported, but its association with morbidity and mortality remains poorly defined. Retrospective study of patients admitted to two EVD Treatment Units, over an eight-month period in 2019, during a large EVD epidemic in the Democratic Republic of the Congo. 333 patients (median age 30 years, 58% female) had at least one creatine kinase (CK) measurement (total 2,229 CK measurements, median 5 (IQR 1-11) per patient). 271 patients (81%) had an elevated CK (>380U/L), 202 (61%) had rhabdomyolysis (CK>1,000 IU/L), and 45 (14%) had severe rhabdomyolysis (≥5,000U/L). Among survivors, the maximum CK level was median 1,600 (IQR 550 to 3,400), peaking 3.4 days after admission (IQR 2.3 to 5.5) and decreasing thereafter. Among fatal cases, the CK rose monotonically until death, with maximum CK level of median 2,900 U/L (IQR 1,500 to 4,900). Rhabdomyolysis at admission was an independent predictor of AKI (aOR 2.2 [95%CI 1.2-3.8], p=0.0065) and mortality (aHR 1.7 [95%CI 1.03-2.9], p=0.037). Rhabdomyolysis is associated with AKI and mortality in EVD patients. These findings may inform clinical practice by identifying lab monitoring priorities and highlighting the importance of fluid management.

Point-of-Care Serum Proenkephalin as an Early Predictor of Mortality in Patients Presenting to the Emergency Department with Septic Shock.

The aim of the present study is to investigate the prognostic utility of point-of-care (POC)-measured proenkephalin (PENK), a novel biomarker, in terms of predicting in-hospital mortality in patients presenting to the emergency department (ED) with septic shock. Bedside PENK was measured in consecutive patients presenting to the ED with septic shock according to the Sepsis-3 clinical criteria. The association of PENK with inflammatory and routine biomarkers, and its role as a predictor of in-hospital mortality, was examined. Sixty-one patients with septic shock [53% females, median age 83 years (IQR 71-88)] were evaluated. Median (IQR) values of creatinine, plasma lactate, soluble urokinase plasminogen activator receptor (SuPAR), procalcitonin and PENK were 1.7 (1.0-2.9) mg/dL, 3.6 (2.1-6.8) mmol/L, 13.1 (10.0-21.4) ng/mL, 2.06 (0.84-3.49) ng/mL, and 205 (129-425) pmol/L, respectively. LogPENK significantly correlated with LogLactate (rho = 0.369, p = 0.004), LogCreatinine (rho = 0.537, p < 0.001), LogProcalcitonin (rho = 0.557, p < 0.001), and LogSuPAR (rho = 0.327, p = 0.011). During hospitalization, 39/61 (64%) patients died. In a multivariable logistic regression model, logPENK was an independent predictor of in-hospital mortality (OR 11.9, 95% CI: 1.7-84.6, p = 0.013). POC PENK levels measured upon presentation to the ED strongly correlated with metabolic, renal and inflammatory biomarkers, and may serve as a predictor of in-hospital mortality in patients with septic shock.

Time to maximum amplitude of thromboelastography can predict mortality in patients with severe COVID-19: a retrospective observational study.

To predict mortality in severe patients with COVID-19 at admission to the intensive care unit (ICU) using thromboelastography (TEG). This retrospective, two-center, observational study involved 87 patients with PCR-and chest CT-confirmed severe COVID-19 who were admitted to at Wuhan Huoshenshan Hospital and the 908th Hospital of Chinese PLA Logistic Support Force between February 2020 and February 2023. Clinic demographics, laboratory results, and outcomes were compared between those who survived and those who died during hospitalization. Thromboelastography showed that of the 87 patients, 14 were in a hypercoagulable state, 25 were in a hypocoagulable state, and 48 were normal, based on the time to maximum amplitude (TMA). Patients who died showed significantly lower α angle, but significantly longer R-time, K-time and TMA than patients who survived. Random forest selection showed that K-time, TMA, prothrombin time (PT), international normalized ratio (INR), D-dimer, C-reactive protein (CRP), aspartate aminotransferase (AST), and total bilirubin (Tbil) were significant predictors. Multivariate logistic regression identified that TMA and CRP were independently associated with mortality. TMA had a greater predictive power than CRP levels based on time-dependent AUCs. Patients with TMA ≥ 26.4 min were at significantly higher risk of mortality (hazard ratio 3.99, 95% Confidence Interval, 1.92-8.27, p < 0.01). TMA ≥26.4 min at admission to ICU may be an independent predictor of in-hospital mortality for patients with severe COVID-19.

Outcomes of Patients Presenting With Non-ST Elevation Myocardial Infarction Who Underwent Surgical Revascularization

Non-ST-segment elevation myocardial infarction (NSTEMI) is a leading cause of emergency hospitalisation across Europe. This study evaluates the in-hospital and mid-term outcomes of patients undergoing coronary artery bypass grafting (CABG) following NSTEMI. A retrospective analysis of all cases undergoing isolated CABG following NSTEMI from September/2017 to September/2022 at our Centre. Patients were stratified according to in-hospital survival. Patient characteristics, operative details, and procedural complications were compared between those who survived and those who did not. Predictors of in-hospital and mid-term mortality were evaluated using logistic and Cox regression modelling. Kaplan Meier analysis was used to generate a survival curve for all alive patients at the time of discharge. Among 1011 patients (median age 64 [56 - 72] years, 852 [84.3%] male), 735 (72.7%) underwent urgent, 239 (23.6%) elective, and 37 (3.7%) emergency CABG. The in-hospital mortality was 1.5% (15/1011 patients). Those who died were more likely to be NYHA class III/IV, have LVEF <21%, severe renal impairment, peripheral vascular disease (PVD), or poor mobility. Emergency procedures, pre-operative ventilation, inotropic support, and intra-aortic balloon pump (IABP) use were also more prevalent among those who died. Logistic regression modelling revealed new postoperative stroke (OR:22.0; 95% CI:3.6-135.5; p=0.001), pre-operative IABP use (11.4; 2.4-53.7; p=0.002), new haemodialysis (9.6; 2.7-34.7; p<0.001), PVD (5.6; 1.6-20.0; p=0.008), and poor mobility (OR: 4.8; 95% CI: 1.3-18.2; p=0.022) as independent predictors of in-hospital mortality. In conclusion, new postoperative stroke, pre-operative IABP use, new haemodialysis, PVD and poor mobility are independent predictors of mortality in NSTEMI patients undergoing isolated CABG.

Predicting the time of mortality among older adult trauma patients: Is frailty the answer?

IntroductionThis study aims to evaluate the temporal trends of mortality among frail versus non-frail older adult trauma patients during index hospitalization. MethodsWe performed a 3-year (2017–2019) analysis of ACS-TQIP. We included all older adult (age ≥65 years) trauma patients. Patients were stratified into two groups (Frail vs. Non-Frail). Outcomes were acute (<24 ​h), early (24–72 ​h), intermediate (72 hours-1 week), and late (>1 week) mortality. ResultsA total of 1,022,925 older adult trauma patients were identified, of which 19.7 ​% were frail. The mean(SD) age was 77(8) years and 57.4 ​% were female. Median[IQR] ISS was 9[4–10] and both groups had comparable injury severity (p ​= ​0.362). On multivariable analysis, frailty was not associated with acute (aOR 1.034; p ​= ​0.518) and early (aOR 1.190; p ​= ​0.392) mortality, while frail patients had independently higher odds of intermediate (aOR 1.269; p ​= ​0.042) and late (aOR 1.835; p ​< ​0.001) mortality. On sub-analysis, our results remained consistent in mild, moderate, and severely injured patients. ConclusionFrailty is an independent predictor of mortality in older adult trauma patients who survive the initial 3 days of admission, regardless of injury severity.

Abstract 1139: Recent Trends And Predictors Of Poor Outcomes In Patients With Chronic Thromboembolic Pulmonary Hypertension Undergoing Pulmonary Artery Thromboendarterectomy.

Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH) occurs due to pulmonary artery obstruction from persistent thromboembolic disease. Pulmonary artery thromboendarterectomy (PTE) is the definitive treatment. In this study, we examine the recent trends, predictors of mortality among patients with CTEPH undergoing PTE. Methods: Using the International Classification of Diseases, 10th edition, Clinical Modification (ICD-10-CM) diagnosis and procedure codes, we queried the National Inpatient Sample 2016 to 2020 for hospitalizations among patients ≥18 years old with a diagnosis of CTEPH who underwent PTE. We examined the recent trends in the uptake of PTE, the difference in mortality by year, race, sex, and US region. Logistic regression was used to identify independent predictors of mortality among this cohort of patients. Results: Our study included 18,195 hospitalizations with CTEPH of which 1,790 (9.8%) (mean [SD] age: 54.0 [14.9] years) underwent PTE. In this cohort, 51.7% were males and 47.3% were females. We observed an increasing trend in the uptake of PTE; 7.3%, 27.1%, and 37.4% for the years 2017, 2018, 2019 respectively. This trend reversed in 2020 (28.2%) ( p=0.9 ). Mortality was recorded among 5.9% of patients with CTEPH who had PTE. No difference in mortality was observed by sex/gender, year, race, or hospital region. ECMO was utilized among 8.4% of patients with CTEPH undergoing PTE. Mortality was higher among those who utilized ECMO compared to those who did not utilize ECMO (36.7% vs. 3.1%, p&lt;0.0001). ECMO utilization was identified as an independent predictor of mortality OR: 18.4, 6.96-48.74, P&lt;0.0001. Sex, HTN, and Obesity were not associated with mortality in this cohort. Conclusion: We observe increasing utilization of pulmonary artery thromboendarterectomy among patients hospitalized with CTEPH and increased mortality among those requiring ECMO. Further research is needed to identify predictors of poor outcomes among patients with CTEPH undergoing PTE.

Sex-Related Differences Between Patients Undergoing Surgery for Acute Type A Aortic Dissection.

Introduction This study aimed to evaluate the sex-specific characteristics and surgical outcomes in patients with acute type A aortic dissection (ATAAD). Materials and methods We reviewed the surgical records of patients who underwent ATAAD repair at our institution between 2004 and 2020 (n=213). Results Of the 213 patients, 100 (46.9%) were male, and 113 (53.1%) were female. Males were younger than females (62.5 vs. 72.9 years, p<0.0001). Females had more nonspecific symptoms (p=0.04), more frequently developed ATAAD before noon (45.0% vs. 53.1%, p=0.01), and had a significantly longer time from onset to surgery (425.1 vs. 595.8 min, p=0.03). The ascending aorta was replaced more frequently in females than in males (54.5% vs. 72.8%, p<0.01). No significant difference was observed in the in-hospital mortality rate between males and females (9.0% vs. 10.6%, p=0.69). The multivariable logistic analysis demonstrated that being male was not an independent predictor of operative mortality (OR, 0.96; 95% CI, 0.18-5.21; p=0.96). At 10 years, males had significantly better long-term survival rates in the unadjusted cohort than females (79.4% vs. 55.9%, p=0.02). Conclusions Male sex was not an independent predictor of early death in patients with ATAAD after surgery, although significant differences were noted in terms of age, onset time, chief complaint, imaging findings, and surgical procedures. A sex-based management strategy involving specific differences should be considered to improve outcomes.

Pronóstico de los pacientes con insuficiencia cardiaca seguidos en unidades acreditadas en el programa SEC-Excelente-IC con relación al tipo de unidad

Introduction and objectivesThe development of specific heart failure (HF) units has improved the management of patients with this disease due to improved organization and resource management. The Spanish Society of Cardiology (SEC) has defined 3 types of HF units (community, specialized, and advanced) based on their complexity and service portfolio. Our aim was to compare the characteristics, treatment, and outcomes of patients with HF according to the type of unit. MethodsWe analyzed data from the SEC-Excelente-IC quality accreditation program registry, with 1716 patients consecutively included in two 1-month cutoffs (March and October) from 2019 to 2021 by 45 SEC-accredited HF units. We compared the characteristics, treatment and 1-year outcomes between the 3 types of units. ResultsOf the 1716 patients, 13.2% were treated in community units, 65.9% in specialized units, and 20.9% in advanced units. The rates of mortality (27.5 vs 15.5/100 patients-year; P<.001), admissions for HF (39.7 vs 29.2/100 patients-year; P=.019), total decompensations (56.1 vs 40.5/100 patients-year; P=.003), and combined death/admission for HF (45.2 vs 31.4/100 patients-year; P=.005) were higher in community units than in specialized/advanced units. Follow-up in a community unit was an independent predictor of higher mortality and admissions at 1 year. ConclusionsCompared with follow-up by more specialized units, follow-up in a community unit was associated with a higher decompensation rate and increased 1-year mortality.Full English text available from:www.revespcardiol.org/en

BLOOD PRESSURE VARIABILITY AS PREDICTOR OF CANCER THERAPY-RELATED CARDIOVASCULAR TOXICITY IN PATIENTS WITH MULTIPLE MYELOMA

Objective: Blood pressure variability (BPV) is an independent predictor of cardiovascular (CV) events and overall mortality. The potential role of BPV in defining CV risk of patients undergoing anticancer therapy with a potential cancer therapy-related cardiovascular toxicity (CTR-CVT) is currently unknown. The aims of this study were: (i) to assess the predictive value of BPV indexes for CTR-CVT development and defining the corresponding cut-off values; (ii) to identify subgroups of subjects based on BPV, through clustering analysis. Design and method: Patients with Multiple Myeloma, who were eligible to anticancer therapy with Carfilzomib, were consecutively enrolled and underwent a baseline evaluation, including office blood pressure (BP) measurement, 24h-Ambulatory Blood pressure Monitoring (ABPM), PWV, and Echocardiography. Short-term BPV was assessed through standard deviation (SD), weighted standard deviation (wSD), coefficient of variation (CoV), average real variability (ARV), and variability independent of the mean (VIM), evaluated on ABPM measurements. Results: The study population included 124 patients (50% female). During follow-up, CTR-CVT occurred in 70 subjects (56.5% of the total population), including both BP and CV events. Night-time BPV was associated to CTR-CVT, independently by BP, age, smoking, and comorbidities as diabetes and renal dysfunction (night-time systolic CoV: adjusted OR 1.11 [1.01-1.22]; night-time systolic VIM adjusted OR 1.17 [1.03-1.35]; night-time diastolic VIM adjusted OR 1.18 [1.01-1.40]). Cut-off for these BPV parameters were identified as predictor of CTR-CVT occurrence: 10.5 for night-time systolic CoV (sensibility 73%, specificity 47%); 7.8 and 6.4 for systolic and diastolic night-time VIM (sensibility 85% for both; specificity 35% and 39%, respectively). Clustering analysis identified a subgroup of subjects characterized by the highest BPV, who had a greater prevalence of events during follow-up, but no differences in other conventional CV risk factors, as BP, dyslipidaemia, diabetes, renal function, and smoking habit, as well as left ventricular mass and global longitudinal strain. Conclusions: Short-term BPV is an independent predictor of CTR-CVT in patients with Multiple Myeloma undergoing therapy with Carfilzomib. The inclusion of these indexes improves CV risk prediction in these subjects and higher BPV is a distinctive feature predicting adverse events, on top of conventional CV risk factors.

Stereotactic radiosurgery in the management of non-small cell lung cancer brain metastases: a prospective study using the NeuroPoint Alliance Stereotactic Radiosurgery Registry.

The literature on non-small cell lung cancer (NSCLC) brain metastases (BMs) managed using stereotactic radiosurgery (SRS) relies mainly on single-institution studies or randomized controlled trials (RCTs). There is a literature gap on clinical and radiological outcomes of SRS for NSCLC metastases in real-world practice. The objective of this study was to benchmark mortality and progression outcomes in patients undergoing SRS for NSCLC BMs and identify risk factors for these outcomes using a national quality registry. The SRS Registry of the NeuroPoint Alliance was used for this study. This registry included patients from 16 enrolling sites who underwent SRS from 2017 to 2022. Data are prospectively collected without a prespecified research purpose. The main outcomes of this analysis were overall survival (OS), out-of-field recurrence, local progression, and intracranial progression. All time-to-event investigations included Kaplan-Meier analyses and multivariable Cox regressions. Two hundred sixty-four patients were identified, with a mean age of 66.7 years and a female proportion of 48.5%. Most patients (84.5%) had a Karnofsky Performance Status (KPS) score of 80-100, and the mean baseline EQ-5D score was 0.539 quality-adjusted life years. A single lesion was present in 53.4% of the patients, and 29.1% of patients had 3 or more lesions. The median OS was 28.1 months, and independent predictors of mortality included no control of primary tumor (hazard ratio [HR] 2.1), KPS of 80 (HR 2.4) or lower (HR 2.4), coronary artery disease (HR 2.8), and 5 or more lesions present at the time of SRS treatment (HR 2.3). The median out-of-field progression-free survival (PFS) was 24.8 months, and the median local PFS was unreached. Intralesional hemorrhage was an independent risk factor of local progression, with an HR of 6.0. The median intracranial PFS was 14.0 months and was predicted by the number of lesions at the time of SRS (3-4 lesions, HR 2.2; 5-14 lesions, HR 2.5). In this real-world prospective study, the authors used a national quality registry and found favorable OS in patients with NSCLC BMs undergoing SRS compared with results from previously published RCTs. The intracranial PFS was mainly driven by the emergence of new lesions rather than local progression. A greater number of lesions at baseline was associated with out-of-field progression, while intralesional hemorrhage at baseline was associated with local progression.

Pediatric Shock: The Magnitude, Its Determinants and Short-Term Outcome on Patients. A Cross-Sectional Hospital-Based Study.

Pediatric shock is a potentially fatal illness which develops after a systemic circulatory system failure in children. It appears to be a common emergency in children and produces substantial morbidity and mortality particularly if there is no early identification and therapy. The extent and causes of shock-induced death among children in Ethiopia have not been sufficiently studied. This study was conducted to evaluate the magnitude, determinants and short-term outcome of shock in pediatric patients who visited Ayder Comprehensive Specialized Hospital in Tigray, Northern Ethiopia. From October 1, 2020, to July 30, 2022, an observational cross-sectional study was carried out at Ayder Comprehensive Specialized Hospital. The study included 132 children from the age of 1 month to 18 years. According to pediatric advanced life support guidelines, shock was diagnosed among patients. To gather information, a pretested questionnaire was employed. To examine the relationship between the independent variables and shock outcome, bivariate logistic regression was performed, and statistical significance was defined as a P-value of 0.05 or lower. The prevalence of shock was 2.2%. This study revealed 70.5% decompensated stage of shock. Mortality rate of shock was 45.5% (95% CI: 37.1-53.8). A delayed presentation by more than one week with an adjusted odd ratio (AOR) of 16.9 (95% CI: 2.3-123), type of shock other than hypovolemic shock with AOR of 8.3 (95% CI: 1.4-48), stage of shock with AOR of 27.8 (95% CI: 2.8-157), requirement of mechanical ventilation with AOR of 11 (95% CI: 2.6-53) and length of hospital stay less than three days with AOR of 9 (95% CI: 1.7-48) were identified as a predictor of mortality by shock in children. According to this study, shock causes a high rate of child mortality. Independent predictors of mortality included delayed presentation, shock type, stage of shock, the need for mechanical ventilation, and brief hospital stay (less than three days).

Risk factors and outcomes of cytomegalovirus infection in the intensive care unit.

Cytomegalovirus (CMV) infection has long been recognized as an important viral syndrome in the immunocompromised host. The disease is less well described in critically-ill patients. We evaluated the risk factors for the development of CMV infection in patients admitted to the intensive care unit (ICU). We also compared the outcomes of CMV infection in ICU patients to those of patients with hematological malignancies. This is a retrospective study composed of three arms: patients admitted to the ICU with infection (ICU + / CMV + arm), patients admitted to the ICU who did not develop CMV infection (ICU + / CMV- arm, and patients with hematological malignancies on the hematology ward without CMV infection (ICU - / CMV + arm). Patients who were admitted to ICU for surgical causes had a decreased risk of CMV infection. On the other hand, receiving corticosteroids and vasoactive drugs was associated with an increased risk of CMV infection with adjusted odds ratios (aOR) of 2.4 and 25.3, respectively. Mortality was higher in ICU + / CMV + patients compared to ICU - / CMV + patients. In the ICU + /CMV + population, male sex and being on mechanical ventilation after CMV infection were independent predictors of mortality (aOR 4.6 and 5.0, respectively). CMV infection in ICU patients is a potentially serious disease requiring close attention. The findings from our study help in identifying patients in the ICU at risk for CMV infection, thereby warranting frequent screening. Patients at high risk of death (male, on mechanical ventilation) should receive prompt treatment and intensive follow-up.

Characteristics and outcomes of patients admitted to intensive care units in Uganda: a descriptive nationwide multicentre prospective study

Intensive care unit (ICU) mortality rates have decreased over time. However, in low-and lower-middle income countries (LMICs), there remains an excess ICU mortality with limited understanding of patient characteristics, treatments, and outcomes from small single centre studies. We aimed therefore, to describe the characteristics, therapies and outcomes of patients admitted to all intensive care units in Uganda. A nationwide prospective observational study including all patients admitted Uganda’s ICUs with available daily charts was conducted from 8th January 2018 to 1st April 2018. Socio-demographics and clinical characteristics including worst vital signs in the first 24 h of admission were recorded with calculation of the National Early Warning Score (NEWS-2) and quick Sequential Organ Function Assessment (qSOFA) score. ICU interventions were recorded during the ICU stay and patients were followed up to 28 days in ICU. The primary outcome was 28 day ICU mortality. Three-hundred fifty-one patients were analysed with mean age 39 (24.1) years, 205 (58.4%) males with 197 (56%) surgical admissions. The commonest indication for ICU admission was postoperative care (42.9%), 214 (61%) had at least one comorbidity, with hypertension 104 (48.6%) most prevalent and 35 (10%) HIV positive. The 28 day ICU mortality was 90/351 (25.6%) with a median ICU stay of 3 (1–7) days. The highest probability of death occurred during the first 10 days with more non-survivors receiving mechanical ventilation (80% vs 34%; p < 0.001), sedation/paralysis (70% vs 50%; p < 0.001), inotropic/vasopressor support (56.7% vs 22.2%; p < 0.001) and renal replacement therapy (14.4% vs 4.2%; p < 0.001). Independent predictors of ICU mortality included mechanical ventilation (HR 3.34, 95% CI 1.48–7.52), sedation/paralysis (HR 2.68, 95% CI 1.39–5.16), inotropes/vasopressor (HR 3.17,95% CI 1.89–5.29) and an HIV positive status (HR 2.28, 95% CI 1.14–4.56). This study provides a comprehensive description of ICU patient characteristics, treatment patterns, and outcomes in Uganda. It not only adds to the global body of knowledge on ICU care in resource-limited settings but also serves as a foundation for future research and policy initiatives aimed at optimizing ICU care in Sub-Saharan Africa.

RV in COPD - The complicated matters of the heart - Correlation of ECHO and biomarker with COPD severity and outcome.

Patients with chronic obstructive pulmonary disease (COPD) have an increased risk of cardiovascular involvement, which is among the leading causes of morbidity and mortality worldwide. Echocardiography (ECHO) could be a reliable, non-invasive tool for predicting the risk of cardiovascular modalities in patients with COPD. Combining the ECHO parameters with highly selective cardiac troponin could predict the severity and outcome of patients with COPD. This prospective observational study was conducted at a tertiary care hospital in South India. All patients who met the criteria were included. Patients with other concomitant chronic lung diseases were excluded. An echocardiographic examination was performed, and blood samples for hs-Tnt were taken on admission for patients admitted with COPD. Categorical variables were analyzed using Pearson's Chi-square test, and the T-test was used to compare the means. One-way analysis of variance (ANOVA) followed by the Bonferroni multiple comparison tests was done to compare different echo parameters concerning COPD severity. The mean tricuspid annulus plane systolic excursion (TAPSE) and right ventricle (RV) fraction area change (FAC) values were lower with the increase in the disease severity (P < 0.001). There was a significant increase in the mean systolic pressures in the right atrium and ventricle in patients with severe COPD (P < 0.001). The mean hs-TnT values were significantly higher in patients with severe COPD (18.86 ± 18.12) and correlated well with the increase in the severity of the disease (P < 0.001). Changes in the echo parameters, such as mean TAPSE and RV FAC values, negatively correlated with COPD severity. There was an increase in systolic pressure in both atria and ventricles with the progression of COPD. Troponin helped predict mortality during hospitalization. Comprehensive echocardiographic parameters, such as TAPSE and RV FAC, help assess the disease's severity, predict mortality, and evaluate whether the proper ventricular function is reliable. Troponin is a valuable adjunct that is an independent and strong predictor of overall mortality in patients with COPD.
