A Simple Risk Score for Predicting Neurologic Outcome in Out-of-Hospital Cardiac Arrest Patients After Targeted Temperature Management.

OBJECTIVES: Although several risk factors for outcomes of out-of-hospital cardiac arrest patients have been identified, the cumulative risk of their combinations is not thoroughly clear, especially after targeted temperature management. Therefore, we aimed to develop a risk score to evaluate individual out-of-hospital cardiac arrest patient risk at early admission after targeted temperature management regarding poor neurologic status at discharge. DESIGN: Retrospective observational cohort study. SETTING: Two large academic medical networks in the United States. PATIENTS: Out-of-hospital cardiac arrest survivors treated with targeted temperature management with age of 18 years old or older. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Based on the odds ratios, five identified variables (initial nonShockable rhythm, Leucocyte count < 4 or > 12 K/µL after targeted temperature management, total Adrenalin [epinephrine] ≥ 5 mg, lack of oNlooker cardiopulmonary resuscitation, and Time duration of resuscitation ≥ 20 min) were assigned weighted points. The sum of the points was the total risk score known as the SLANT score (range 0-21 points) for each patient. Based on our risk prediction scores, patients were divided into three risk categories as moderate-risk group (0-7), high-risk group (8-14), and very high-risk group (15-21). Both the ability of our risk score to predict the rates of poor neurologic outcomes at discharge and in-hospital mortality were significant under the Cochran-Armitage trend test (p < 0.001 and p < 0.001, respectively). CONCLUSIONS: The risk of poor neurologic outcomes and in-hospital mortality of out-of-hospital cardiac arrest survivors after targeted temperature management is easily assessed using a risk score model derived using the readily available information. Its clinical utility needed further investigation.

Neutrophil-to-lymphocyte ratio as a predictor for outcomes in patients with short-term emergency department revisits.

BACKGROUND: Analysis of short-term emergency department (ED) revisits is a common emergency care quality assurance practice. Previous studies have explored various risk factors of ED revisits; however, laboratory data were usually omitted. This study aimed to evaluate the prognostic significance of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte (PLR), and systemic immune-inflammation index (SII) in predicting outcomes of patients revisiting the ED. METHODS: This retrospective observational cohort study investigated short-term ED revisit patients. The primary outcome measure was high-risk ED revisit, a composite of in-hospital mortality or intensive care unit (ICU) admission after 72-h ED revisit. The NLR, PLR, and SII were investigated as potential prognostic predictors of ED revisit outcomes. RESULTS: A total of 1916 encounters with short-term ED revisit patients were included in the study; among these, 132 (6.9%) encounters, comprising 57 in-hospital mortalities and 95 ICU admissions, were high-risk revisits. High-risk revisit patients had significantly higher NLR, PLR, and SII (11.6 vs. 6.6, p<0.001; 26.2 vs. 18.9, p=0.004; 2209 vs. 1486, p=0.002, respectively). Multiple regression analysis revealed revisit-NLR as an independent factor for predicting poor outcomes post-ED revisits (Odds Ratio: 1.031, 95% Confidence Interval: 1.017-1.045, p<0.001); an optimal cut-off value of 7.9 was proven for predicting high-risk ED revisit. CONCLUSION: The intensity of the inflammatory response expressed by NLR was an independent predictor for poor outcomes of ED revisits and should be considered when ED revisits occur. Future prediction models for ED revisit outcomes can include revisit-NLR as a potential predictor to reflect the progressive conditions in ED patients.

Percutaneous catheter drainage versus percutaneous needle aspiration for liver abscess: a systematic review, meta-analysis and trial sequential analysis.

OBJECTIVE: To compare the effectiveness and safety of percutaneous catheter drainage (PCD) against percutaneous needle aspiration (PNA) for liver abscess. DESIGN: Systematic review, meta-analysis and trial sequential analysis. DATA SOURCES: PubMed, Web of Science, Cochrane Library, Embase, Airiti Library and ClinicalTrials.gov were searched from their inception up to 16 March 2022. ELIGIBILITY CRITERIA: Randomised controlled trials that compared PCD to PNA for liver abscess were considered eligible, without restriction on language. DATA EXTRACTION AND SYNTHESIS: Primary outcome was treatment success rate. Depending on heterogeneity, either a fixed-effects model or a random-effects model was used to derive overall estimates. Review Manager V.5.3 software was used for meta-analysis. Trial sequential analysis was performed using the Trial Sequential Analysis software. Certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation system. RESULTS: Ten trials totalling 1287 individuals were included. Pooled analysis revealed that PCD, when compared with PNA, enhanced treatment success rate (risk ratio 1.16, 95% CI 1.07 to 1.25). Trial sequential analysis demonstrated this robust finding with required information size attained. For large abscesses, subgroup analysis favoured PCD (test of subgroup difference, p<0.001). In comparison to PNA, pooled analysis indicated a significant benefit of PCD on time to achieve clinical improvement or complete clinical relief (mean differences (MD) -2.53 days; 95% CI -3.54 to -1.52) in six studies with 1000 patients; time to achieve a 50% reduction in abscess size (MD -2.49 days; 95% CI -3.59 to -1.38) in five studies with 772 patients; and duration of intravenous antibiotic use (MD -4.04 days, 95% CI -5.99 to -2.10) in four studies with 763 patients. In-hospital mortality and complications were not different. CONCLUSION: In patients with liver abscess, ultrasound-guided PCD raises the treatment success rate by 136 in 1000 patients, improves clinical outcomes by 3 days and reduces the need for intravenous antibiotics by 4 days.

Hospital outcomes and cumulative burden from complications in type 2 diabetic sepsis patients: a cohort study using administrative and hospital-based databases.

BACKGROUND: The association between type 2 diabetes and hospital outcomes of sepsis remains controversial when severity of diabetes is not taken into consideration. We examined this association using nationwide and hospital-based databases. METHODS: The first part of this study was mainly conducted using a nationwide database, which included 1.6 million type 2 diabetic patients. The diabetic complication burden was evaluated using the adapted Diabetes Complications Severity Index score (aDCSI score). In the second part, we used laboratory data from a distinct hospital-based database to make comparisons using regression analyses. RESULTS: The nationwide study included 19,719 type 2 diabetic sepsis patients and an equal number of nondiabetic sepsis patients. The diabetic sepsis patients had an increased odds ratio (OR) of 1.14 (95% confidence interval 1.1-1.19) for hospital mortality. The OR for mortality increased as the complication burden increased [aDCSI scores of 0, 1, 2, 3, 4, and ⩾5 with ORs of 0.91, 0.87, 1.14, 1.25, 1.56, and 1.77 for mortality, respectively (all p < 0.001)].The hospital-based database included 1054 diabetic sepsis patients. Initial blood glucose levels did not differ significantly between the surviving and deceased diabetic sepsis patients: 273.9 ± 180.3 versus 266.1 ± 200.2 mg/dl (p = 0.095). Moreover, the surviving diabetic sepsis patients did not have lower glycated hemoglobin (HbA1c; %) values than the deceased patients: 8.4 ± 2.6 versus 8.0 ± 2.5 (p = 0.078). CONCLUSIONS: For type 2 diabetic sepsis patients, the diabetes-related complication burden was the major determinant of hospital mortality rather than diabetes per se, HbA1c level, or initial blood glucose level.

[Study on determining the composition of ternary complex (AI-CAS-CTMAB) with the ratio of double peak values at double wavelengths by UV spectrophotometry].

In the present paper, the composition of complex Al-CAS-CTMAB was studied with the ratio of double peak values at dual-wavelengths by UV spectrophotometry. First, the composition of complex of Al-CAS was determined in this method, Al:CAS = 1:2. The absorption of ternary complex(Al-CAS-CTMAB) was determined with reference reagent of the complex Al-CAS. The epsilon values of Al-CAS and Al-CAS-CTMAB were determined with water reference. The composition of complex Al (CAS)n1 (CTMAB)n2 was calculated with the formula: [formula: see text] CAS:CTMAB = 1:1; Al:CAS:CTMAB = 1:2:2. The calculated value and that obtained by traditional method are agreeable. The method is reliable for determining composition of ternary complexes.
