This paper presents a novel risk stratification method using extreme learning machine (ELM). ELM was integrated into a scoring system to identify the risk of cardiac arrest in emergency department (ED) patients. The experiments were conducted on a cohort of 1025 critically ill patients presented to the ED of a tertiary hospital. ELM and voting based ELM (V-ELM) were evaluated. To enhance the prediction performance, we proposed a selective V-ELM (SV-ELM) algorithm. The results showed that ELM based scoring methods outperformed support vector machine (SVM) based scoring method in the receiver operation characteristic analysis.

This article is based on the use of GE combined with longitudinal lag time to quantify cardiac MRI screening for amyloidosis autologous thousand-cell transplantation, combined with clinical routine risk stratification, method for risk assessment of patients with amyloidosis and monitor the patient’s evaluation of the efficacy after treatment. Cardiac involvement with systemic amyloidosis is of great significance for both treatment and prognosis assessment, and is essential for quantitative and qualitative diagnosis or objectively providing prognostic value. In summary, myocardial amyloidosis needs to be studied before heart failure. It is recommended that patients undergo routine cardiac MRI examination to comprehensively evaluate cardiac morphology, function, risk stratification, prognosis, and treatment guidance. Diagnosis based on a single modality has been replaced by a comprehensive multi-modality method, and there is sufficient evidence to show the potential value of cardiac. However, with the continuous improvement of quality and value in the medical field, the field of cardiac will inevitably develop. The predicted and baseline indexes of myocardial strain predicted cardiac remission were 0.96 and 0.79, respectively. When the predictive value of clinical routine indicators and cardiac indicators is analyzed using blood response as the evaluation standard, the reduction in end-diastolic volume/body surface area (P = 0.031) can predict complete haematological remission. Folded cross-validation test shows that the end-diastolic volume/body surface area reduction and the baseline index IgG combined with myocardial strain predict AUC of complete blood remission of 0.78 and 0.76, respectively. This study will also continue to follow up and increase the sample size to verify the current conclusions.

Background: Postoperative pulmonary complications (PPC) are one of the commonest complications following gastrointestinal surgery. They lead to increase in morbidity and mortality. Lactate dehydrogenase (LDH) is an enzyme present in essentially all major organ systems. Studies have shown measurement of its activity levels and its isoenzyme pattern may provide additional information about lung and pulmonary endothelial cell injury. The objectives of the present study were to study the levels of serum LDH in patients with and without post-operative pulmonary complications following emergency abdominal surgery.Methods: The study was designed as an observational study. All patients ≥18 years of age undergoing gastrointestinal surgery, excluding those with prior lung pathology were included in the study. The demographic parameters, clinical parameters and laboratory parameters along with details of pulmonary complications were recorded. Serum LDH level were assessed on admission. Levels of serum LDH were compared between patients with and without post-operative pulmonary infections and were assessed for significance.Results: Incidence of PPC was 28% in our study. There was significant difference in the mean age in the group with and without PPC (p=<0.001). Smoking habit, serum albumin total protein and upper abdomen incision surgery were associated with increased incidence of PPC. Pleural effusion was the commonest PPC seen in patients. Serum LDH was not significantly associated with the incidence of PPC.Conclusions: Pre-operative serum LDH level is not a predictive factor for occurrence of postoperative pulmonary complication. Age, smoking, total protein, serum albumin, upper abdomen incision were found to associated with increased risk of PPCs.
