Observational Study
Heart rate variability based machine learning models for risk prediction of suspected sepsis patients in the emergency department.
Early identification of high-risk septic patients in the emergency department (ED) may guide appropriate management and disposition, thereby improving outcomes. We compared the performance of machine learning models against conventional risk stratification tools, namely the Quick Sequential Organ Failure Assessment (qSOFA), National Early Warning Score (NEWS), Modified Early Warning Score (MEWS), and our previously described Singapore ED Sepsis (SEDS) model, in the prediction of 30-day in-hospital mortality (IHM) among suspected sepsis patients in the ED. Adult patients who presented to Singapore General Hospital (SGH) ED between September 2014 and April 2016, and who met ≥2 of the 4 Systemic Inflammatory Response Syndrome (SIRS) criteria were included. ⋯ A total of 214 patients were included, of whom 40 (18.7%) met the outcome. Gradient boosting was the best model with a F1 score of 0.50 and AUPRC of 0.35, and performed better than all the baseline comparators (SEDS, F1 0.40, AUPRC 0.22; qSOFA, F1 0.32, AUPRC 0.21; NEWS, F1 0.38, AUPRC 0.28; MEWS, F1 0.30, AUPRC 0.25). A machine learning model can be used to improve prediction of 30-day IHM among suspected sepsis patients in the ED compared to traditional risk stratification tools.

Telomere length is closely related to the onset and prognosis of ischemic stroke. This study was to investigate the relationship between telomere length and the incidence of ischemic stroke in Han population of northern China. ⋯ Our results indicate that shorter telomere length has some connection with the risk of ischemic stroke in the northern Chinese Han population. Telomere length might serve as a potential candidate biomarker for ischemic stroke. This requires a large sample to be further verified.

Gout occurs mainly in joints, but rarely in the spine. In the spine, urate crystals can cause intervertebral space instability but rarely lead to retrolisthesis. Here, we present an extremely rare disease with gout invaded the intervertebral disc with lumbar retrolisthesis. ⋯ Gouty spondylodiscitis can cause intervertebral space instability. Sagittal imbalance and degeneration of disc with decreasing of segmental disc height are considered as the main factors of retrolisthesis. The appearance may lead to misdiagnose a patient with gout history with a destruction of the intervertebral space. Surgery is a compromise method for gouty spondylodiscitis patients with urgent neurological symptoms.

Prognostic value of serum albumin for patients with acute aortic dissection: A retrospective cohort study.
Serum albumin (SA) is associated with inflammation and thrombosis, which are involved in acute aortic dissection (AAD). Our aim was to investigate the effect of SA level on survival in patients with AAD. We analyzed 777 patients with AAD. ⋯ Kaplan-Meier analysis showed that survival was significantly lower in patients with hypoalbuminemia compared to those without, regardless of AAD type (type A: log-rank χ = 14.71; P <.001; Type B: log-rank χ = 10.42; P = .001). After adjusting for confounding factors, hypoalbuminemia was an independent predictor of in-hospital mortality in patients with either type A (HR, 2.492; 95% confidence interval [CI], 1.247-4.979; P = .010) or type B (HR, 8.729; 95% CI, 1.825-41.736; P = .007). SA is independently associated with increased in-hospital mortality in both type A and B AAD.

Prognostic significance of neutrophil-lymphocyte ratio and carbohydrate antigen 19-9 in patients with gallbladder carcinoma.
The neutrophil-lymphocyte ratio (NLR) is an immune response-related indicator and it is associated with poor prognosis of various cancers. The carbohydrate antigen19-9 (CA19-9) is a tumor-associated antigen and it has prognostic relevance in gallbladder carcinoma (GBC). We aimed to analyze whether preoperative NLR and serum CA19-9 were associated with outcomes of GBC patients after surgery with curative intent. ⋯ The median survival time in low NLR and CA19-9 group was better than high NLR and CA19-9 group (P < .05). The preoperative NLR and serum CA19-9 are associated with prognosis of patients with GBC. High NLR and high CA19-9 were predictors of poor long-term outcome among patients with GBC undergoing curative surgery.
