RESUMEN
BACKGROUND: Amplitude-integrated electroencephalography (aEEG) has been used as a tool to recognize brain activity in children with hypoxic encephalopathy. OBJECTIVES: To assess the prognostic value of aEEG during the post-resuscitation period of adult cardiogenic cardiac arrest, comatose survivors were monitored within 24 h of a return of spontaneous circulation using aEEG. METHODS: Forty-two consecutive patients experiencing cardiac arrest were retrospectively enrolled, and a return of spontaneous circulation was achieved in all cases. These patients were admitted to the Coronary Intensive Care Unit due to cardiogenic cardiac arrest. The primary outcome was the best neurologic outcome within 6 months after resuscitation, and the registered patients were divided into two groups based on the Cerebral Performance Category (CPC) scale (CPC 1-2, good neurologic function group; CPC 3-5, poor neurologic function group). All patients received an aEEG examination within 24 h after a return of spontaneous circulation, and the parameters and patterns of aEEG recordings were compared. RESULTS: Nineteen patients were in the good neurologic function group, and 23 were in the poor group. The four voltage parameters (minimum, maximum, span, average) of the aEEG recordings in the good neurologic function groups were significantly higher than in the poor group. Moreover, the continuous pattern, but not the status epilepticus or burst suppression patterns, could predict mid-term good neurologic function. CONCLUSIONS: aEEG can be used to predict neurologic outcomes based on the recordings' parameters and patterns in unconscious adults who have experienced a cardiac collapse, resuscitation, and return of spontaneous circulation.
RESUMEN
BACKGROUND: Out-of-hospital cardiac arrest (OHCA) has low survival rates, and few patients achieve a desirable neurological outcome. Anemia is common among OHCA patients and has been linked to worse outcomes, but its impact following the return of spontaneous circulation (ROSC) is unclear. This study examines the relationship between anemia burden and clinical outcomes in OHCA patients. HYPOTHESIS: Higher anemia burden after ROSC may be related to higher mortality and worse neurologic outcomes. METHODS: Patients who experienced OHCA and had ROSC were enrolled retrospectively. Anemia burden was defined as the area under curve from the target hemoglobin level over a 72-h period after OHCA. Hemoglobin level was measured at 12-h intervals. The clinical outcomes of the study included mortality and neurological outcomes at Day 30. RESULTS: The study enrolled 258 nontraumatic OHCA patients who achieved ROSC between January 2017 and December 2021. Among the 162 patients who survived more than 72 h, a higher anemia burden, specifically target hemoglobin levels below 7 (hazard ratio [HR]: 1.129, 95% confidence interval [CI]: 1.013-1.259, p = .029), 8 (HR: 1.099, 95% CI: 1.014-1.191, p = .021), and 9 g/dL (HR: 1.066, 95% CI: 1.001-1.134, p = .046) was associated with higher 30-day mortality. Additionally, anemia burden with target hemoglobin levels below 7 (HR: 1.129, 95% CI: 1.016-1.248; p = .024) and 8 g/dL (HR: 1.088; 95% CI: 1.008-1.174, p = .031) was linked to worse neurological outcomes. CONCLUSIONS: Anemia burden predicts 30-day mortality and neurological outcomes in OHCA patients who survive more than 72 h. Maintaining higher hemoglobin levels within the first 72 h after ROSC may improve short-term outcomes.

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.

The predictive value of non-invasive electrocardiographic examination findings for the risk of sudden cardiac death (SCD) in populations with structurally normal hearts remains unclear. This study aimed to investigate the characteristics of the QRS vectorcardiography of surface electrocardiography in patients with structurally normal hearts who experienced SCD. We consecutively enrolled patients who underwent vectorcardiography between March 2017 and December 2018 in a tertiary referral medical center. These patients didn't have structural heart diseases, histories of congestive heart failure, or reduced ejection fraction, and they were classified into SCD (with aborted SCD history and cerebral performance category score of 1) and control groups (with an intervention for atrioventricular node reentrant tachycardia and without SCD history). A total of 162 patients (mean age, 54.3±18.1 years; men, 75.9%), including 59 in the SCD group and 103 in the control group, underwent propensity analysis. The baseline demographic variables, underlying diseases, QRS loop descriptors (the percentage of the loop area, loop dispersion, and inter-lead QRS dispersion), and other electrocardiographic parameters were compared between the two groups. In the univariate and multivariate analyses, a smaller percentage of the loop area (odds ratio, 0.0003; 95% confidence interval, 0.00-0.02; p<0.001), more significant V4-5 dispersion (odds ratio, 1.04; 95% confidence interval, 1.02-1.07; p = 0.002), and longer QRS duration (odds ratio, 1.05; 95% confidence interval, 1.00-1.10; p = 0.04) were associated with SCD. In conclusion, the QRS loop descriptors of surface electrocardiography could be used as non-invasive markers to identify patients experiencing aborted SCD from a healthy population. A decreased percentage of loop area and elevated V4-5 QRS dispersion values assessed using vectorcardiography were associated with an increased risk of SCD in patients with structurally normal hearts.

In the present study, solid-state fermentation of black bean with various GRAS filamentous fungi including Aspergillus awamori, Aspergillus oryzae, Aspergillus sojae, Rhizopus azygosporus and Rhizopus sp. No. 2 was preformed to prepared koji. Mycelial propagation of starter organisms and antioxidative activity, including alpha-alpha-diphenyl-2-picyl-hydoxyl (DPPH) radicals, Fe2+-chelating ability, and reducing activity, were examined. Depending upon the starter organism, various amounts of mycelial propagation (23.5-67.3 mg/k koji) were found in the prepared black bean kojis. The methanol extracts of all the black bean kojis, except that prepared with Rhizopus sp. No. 2, exhibited higher levels of DPPH free radical-scavenging activity, Fe2+-chelating activity, and reducing power than did the non-fermented black bean. Taking into account methanol extract content, all the prepared kojis showed greater antioxidative activity than non-fermented black bean. Among the various koji extracts examined, extract of A. awamori-koji exhibited the highest antioxidative activity as did the A. awamori-koji when comparing its antioxidative activity with that of other kojis and non-fermented black bean. In general, the total extractable phenolic compounds and anthocyanins content in black beans increased after fermentation. This might lead to the increased antioxidant activities of black bean kojis observed.

BACKGROUND: To describe the patterns of non-trauma emergency department (ED) resource utilization, cost of visit, acuity level, and admission rate in older adult patients in Taiwan. METHODS: This is a retrospective observational cohort study conducted at the Taipei Veterans General Hospital with an annual ED population of 80,000 patients. Patients aged ≥20 years with non-trauma ED visits from 2005 to 2012 were included in the study. RESULTS: We analyzed 441,665 ED visits. Older adult patients had higher ED usage, with the ratio of their ED visit and population being 3.56, 8.34, and 7.64 in the age groups 70-79, 80-89, and ≥90 years, respectively. ED cost, acuity level, and risks of intensive care unit (ICU) admission increased with increasing age. Compared with patients aged 20-29 years, patients aged ≥90 years required almost twice as much ED resources per visit [adjusted risk ratio (aRR), 1.98]. aRRs for high acuity in the age groups 70-79, 80-89, and ≥90 years were 1.96, 1.87, and 1.91, respectively. The risk of ICU admission in the age groups 40-49, 50-59, 70-79, and ≥90 years also increased by 3-fold (aRR, 2.99), 4-fold (aRR, 4.09), >6-fold (aRR, 6.66), and almost 10-fold (aRR, 9.84), respectively, compared with that in the age group 20-29 years. Among patients aged ≥90 years, 2.9% with low acuity still required ICU admission, whereas 25.1% with high acuity required ICU admission. CONCLUSION: Our study shows that older adult patients are associated with more ED visits and higher acuity, higher ED costs, and higher risks of admission to both the ordinary ward and ICU than younger adult patients.

BACKGROUND: This study applied a new strategy, termed high-turnover utility bed intervention, to offer early admission chances for emergency department (ED) patients and alleviate ED crowding. METHODS: This before-and-after observational cohort study was conducted at the ED of an urban tertiary hospital. On January 1, 2012, 14 utility beds were prepared exclusively for ED patient use. A strict 48-hour course limit for each patient was formulated to govern these high-turnover beds. The primary outcome measure for this study was ED length of stay. Secondary outcome measures were the number of ED admissions, patients who left without being seen, and revisits within 72 hours of discharge, as well as the outcomes of cardiac arrest management and ambulance diversion hours. RESULTS: There were 70,515 adult ED visits enrolled during the preintervention period (January-December 2011), and 69,706 during the postintervention period (July 2012-June 2013). In the postintervention period, this new strategy offered 1401 early admission opportunities. The ambulance diversion hours decreased prominently from 5.4 hours to 1.6 hours per day. A shortening in ED length of stay from 9.7 hours to 8.0 hours was achieved, mainly in cases of nontrauma. More patients (31.2% vs. 29.7%) were admitted to the wards with a lower discharge rate in the postintervention period. Additionally, there was no difference in ED revisit within 72 hours and cardiac arrest management. CONCLUSION: The high-turnover ED utility bed intervention offered improved admission chance and alleviated ED crowding output. ED efficiency improved, with shortened ED length of stay and fewer ambulance diversion hours.

This study was conducted to compare the transformation of both isoflavone derivatives (aglycones, beta-glucosides, and acetyl and malonyl gluclucosides) and beta-glucosidase activity in kojis fermented with various generally recognized as safe filamentous fungi including Aspergillus awamori, Aspergillus oryzae, Aspergillus sojae, Rhizopus azygosporus, and Rhizopus sp. no. 2. Solid fermentation was performed to prepare the kojis by inoculating the steamed black beans with starter organism and culturing at 30 degrees C for 3 days. Results revealed that fermentation caused a marked increase in the content of aglycone (daidzein, glycitein, and genistein), the bioactive isoflavone, and a significant reduction in the content of beta-glucoside isoflavone (daidzin, glycitin, and genistin), compared with the unfermented steamed black bean. The extent of increased aglycone and reduced beta-glucoside isoflavone content varied with the starter organism used. Among the various black bean kojis prepared, the Rhizopus sp. no. 2 koji showed the highest level of enhancement in aglycone content. In the Rhizopus sp. no. 2 koji, the percentage of aglycone to total isoflavone increased from an initial approximately 2.9 to approximately 58.9% after fermentation. In comparison, the percentages found in kojis prepared with other starter organisms ranged from 18.9 to 38.9% after fermentation. Further preparations of black bean kojis with A. awamori at different cultivation temperatures (25, 30, and 35 degrees C) and various fermentation periods (1-5 days) revealed that koji prepared at 30 degrees C for 4 days showed the highest content of aglycones, with 7.7-, 5.7-, and 4.8-fold increases in the content of daidzein, genistein, and glycitein, respectively. In addition, the increase of aglycone content and the increase of beta-glucosidase activity during the fermentation of this koji showed a similar trend.

The carbapenem breakpoints set by different organizations for Acinetobacter are discordant, but supporting clinical data are lacking. This study aimed to provide the first clinical outcome data to support the carbapenem breakpoints for Acinetobacter baumannii (Ab) group in patients with bacteremia. This study included 117 adults who received carbapenems for treatment of Ab group bacteremia in Taipei Veterans General Hospital over an 8-year period. We analyzed 30-day mortality rates among patient groups acquiring isolates with different carbapenem minimal inhibitory concentrations (MICs). The carbapenem MIC breakpoint derived from classification and regression tree (CART) analysis to delineate the risk of 30-day mortality was between MICs of ≤ 4 mg/L and ≥ 8 mg/L. Mortality rate was higher in patients acquiring isolates with carbapenem MIC ≥ 8 mg/L than ≤ 4 mg/L, by bivariate (54.9% [28/51] vs 25.8% [17/66]; P = 0.003) and survival analysis (P = 0.001 by log-rank test). Multivariate analysis using logistic regression and Cox regression models including severity of illness indices demonstrated that treating patients with Ab group bacteremia caused by isolates with a carbapenem MIC ≥ 8 mg/L with carbapenem was an independent predictor of 30-day mortality (odds ratio, 5.125; 95% confidence interval [CI], 1.946-13.498; P = 0.001, and hazard ratio, 2.630; 95% CI, 1.431-4.834; P = 0.002, respectively). The clinical outcome data confirmed that isolates with MIC ≤ 4 mg/L were susceptible to carbapenem, and those with MIC ≥ 8 mg/L were resistant in patients with Ab group bacteremia.

BACKGROUND: Fewer pauses and better chest compression quality are thought to improve overall survival following cardiac arrest. This study aimed to measure the outcomes of adult nontraumatic out-of-hospital cardiac arrests (OHCAs) treated with 5:1 compressions-to-ventilations (Thumper 1007) or continuous chest compressions with ventilation (Thumper 1008 CCV) mechanical cardiopulmonary resuscitation (CPR) within a specified period of time. METHODS: A retrospective observational cohort study of 515 adults with OHCA was conducted at the emergency department of an urban tertiary hospital. There were 307 patients in the Thumper 1007 phase (January 2008 to December 2009) and 208 patients in the Thumper 1008 CCV phase (January 2010 to May 2011). Return of spontaneous circulation (ROSC) and survival to hospital discharge were the primary outcome measures. RESULTS: Patients in the Thumper 1007 and Thumper 1008 CCV phases had comparable results with the following exceptions: less hypertension (42.4% vs. 62.0%), cerebrovascular accidents (11.4% vs. 25.0%), and faster emergency medical service response time intervals (mean, 3.7 vs. 4.5 minutes) with the Thumper 1007. The average ambulance transport time was 6.1 minutes in both phases. The rates of ROSC [35.1% vs. 23.5%; adjusted odds ratio (OR), 1.616; 95% confidence interval (CI), 1.073-2.432] and survival to hospital discharge (10.1% vs. 4.2%; adjusted OR 2.431; 95% CI, 1.154-5.120) were significantly higher with the Thumper 1008 CCV than with the Thumper 1007. Favorable neurologic outcome upon discharge, defined as cerebral performance category scores of 1 (good performance) or 2 (moderate disability), was not significantly different between the two phases [1.6% (5/307) vs. 1.9% (4/208); p = 0.802]. The Thumper 1008 CCV provided significantly faster average chest compression rates and shorter no-chest compression intervals than the Thumper 1007 after activation. CONCLUSION: In an emergency department with short ambulance transport times, continuous chest compressions with ventilation through mechanical CPR showed improved outcomes, including ROSC and survival to hospital discharge, in an adult with OHCA. However, there are a variety of confounding influences that may affect the validity of conclusions that have been drawn.

Dizziness is a common problem in patients seeking medical help and is often associated with imbalance and handicap. This study aimed to reveal whether the perception of unsteadiness could be an indication of greater imbalance and handicap in these patients. Patients with dizziness were categorized into two groups, steady patients (n = 15) and unsteady patients (n = 23), based on the presence or absence of self-perceived unsteadiness. The level of self-perceived handicap was evaluated by the Dizziness Handicap Inventory. Static balance ability was evaluated using a force platform and the center of pressure motion was calculated during various quiet standing conditions. Dynamic balance ability was evaluated by the functional forward reach test and Dynamic Gait Index. All the patients also went through isometric strength tests of the lower extremities. It was found that all patients reported themselves to be handicapped by dizziness. Patients who perceived themselves to be unsteady had greater handicap and poorer static standing, but did not differ from the steady patients in regard to muscle strength or functional balance tests. Thus, self- perceived unsteadiness was associated with greater handicap and poorer static balance in dizzy patients. In clinical management of these patients, special attention should be paid to balance and handicap.
