The impact of COVID-19 epidemic on emergency department visits of older patients in Taiwan.

BACKGROUND: The number of emergency department (ED) visits has significantly declined since the COVID-19 pandemic. In Taiwan, an aged society, it is unknown whether older adults are accessing emergency care during the COVID-19 epidemic. Therefore, this study aimed to investigate the impact of COVID-19 on the ED visits and triage, admission, and intensive care unit (ICU) hospitalization of the geriatric population in a COVID-19-dedicated medical center throughout various periods of the epidemic. METHODS: A retrospective chart review of ED medical records from April 9 to August 31, 2021 were conducted, and demographic information was obtained from the hospital's computer database. The period was divided into pre-, early-, peak-, late-, and post-epidemic stages. For statistical analysis, one-way analysis of variance followed by multiple comparison tests (Bonferroni correction) were used. RESULTS: A statistically significant decrease in the total number of patients attending the ED was noted during the peak-, late-, and post-epidemic stages. In the post-epidemic stage, the number of older patients visiting ED was nearly to that of the pre-epidemic stage, indicating that older adults tend to seek care at the ED earlier than the general population. Throughout the entire epidemic period, there was no statistically significant reduction in the number of the triage 1& 2 patients seeking medical attention at the emergency department. In the entire duration of the epidemic, there was no observed reduction in the admission of elderly patients to our hospital or ICU through the ED. However, a statistically significant decrease was observed in the admission of the general population during the peak epidemic stage. CONCLUSIONS: During the peak of COVID-19 outbreak, the number of ED visits was significantly affected. However, it is noteworthy that as the epidemic was gradually controlled, the older patients resumed their ED visits earlier that the general population as indicated by the surge in their number. Additionally, in the patient group of triage 1& 2, which represents a true emergency, the number did not show a drastic change.

Cognitive Screening via Comprehensive Geriatric Assessment of Older Patients for the Risk Factors of Hospital Revisit/Readmission after Emergency Department Visit at 3-Month Follow-Up.

INTRODUCTION: Cognitive impairment (COIM) is a major challenge for healthcare systems and is associated with an increased risk of adverse outcomes in older people visiting emergency departments (EDs). Owing to global aging, both cognitive screening and comprehensive geriatric assessment (CGA) application in ED settings are developing areas of geriatric emergency medicine. Meanwhile, the association between clinical outcomes of COIM; cognitive impairment, no dementia (CIND); and dementia in the ED could be better investigated. Our study aims to identify individuals with COIM from older patients in the ED via CGA and to describe the association of CIND and dementia with prognosis in ED visits. METHODS: A prospective cross-sectional study was conducted in the ED of the Taipei Veterans General Hospital, a medical center located in Taipei, Taiwan, from August 2018 to November 2020. Patients aged ≥75 years with and without COIM were compared using data obtained from the CGAs conducted by trained nurses. RESULTS: A total of 823 older patients were enrolled in the study and underwent CGA. Of these, 463 (56.3%) were diagnosed with COIM, of which 292 (35.5%) were diagnosed with dementia; and 171 (20.8%), CIND. Between the no-COIM and COIM groups, the COIM group had a higher rate of hospital admission (p = 0.002) and mortality at 3 months (p < 0.05). Among the no-COIM, CIND, and dementia groups, ED disposition (p = 0.001) and the rate of revisit/readmission (p < 0.05) showed significant differences. In particular, the dementia group had a significantly higher rate of revisit/readmission as compared to the CIND group among the three groups. DISCUSSION/CONCLUSION: Older patients with COIM had a higher rate of hospital admission and mortality at the 3-month follow-up than older patients without COIM. Among the no-COIM, CIND, and dementia groups, patients with dementia had significantly increased risks of hospital admission and revisit/readmission. The early detection of COIM, and even dementia, could help ED physicians formulate strategies with geriatric specialists to improve mortality outcomes and revisit/readmission.

Impact of Metabolic Surgery on Gut Microbiota and Sera Metabolomic Patterns among Patients with Diabetes.

Metabolic surgery is a promising treatment for obese individuals with type 2 diabetes mellitus (T2DM), but the mechanism is not completely understood. Current understanding of the underlying ameliorative mechanisms relies on alterations in parameters related to the gastrointestinal hormones, biochemistry, energy absorption, the relative composition of the gut microbiota, and sera metabolites. A total of 13 patients with obesity and T2DM undergoing metabolic surgery treatments were recruited. Systematic changes of critical parameters and the effects and markers after metabolic surgery, in a longitudinal manner (before surgery and three, twelve, and twenty-four months after surgery) were measured. The metabolomics pattern, gut microbiota composition, together with the hormonal and biochemical characterizations, were analyzed. Body weight, body mass index, total cholesterol, triglyceride, fasting glucose level, C-peptide, HbA1c, HOMA-IR, gamma-glutamyltransferase, and des-acyl ghrelin were significantly reduced two years after metabolic surgery. These were closely associated with the changes of sera metabolomics and gut microbiota. Significant negative associations were found between the Eubacterium eligens group and lacosamide glucuronide, UDP-L-arabinose, lanceotoxin A, pipercyclobutanamide B, and hordatine B. Negative associations were identified between Ruminococcaceae UCG-003 and orotidine, and glucose. A positive correlation was found between Enterococcus and glutamic acid, and vindoline. Metabolic surgery showed positive effects on the amelioration of diabetes and metabolic syndromes, which were closely associated with the change of sera metabolomics, the gut microbiota, and other disease-related parameters.

Prognostic significance of emergency department modified early warning score trend in critical ill elderly patients.

OBJECTIVE: To explore the relationship between trends in emergency department modified early warning score (EDMEWS) and the prognosis of elderly patients admitted to the intensive care unit (ICU). METHODS: Consecutive non-traumatic elderly ED patients (≥65 years old) admitted to the ICU between July 2018 and June 2019 were enrolled in this retrospective cohort study. The selected patients had at least 2 separate MEWS during their ED stay. Detailed patient information was retrieved initially from the ICU database of our hospital and then crosschecked with electronic medical recording system to confirm the completeness and correctness of the data. Patients who had do-not-resuscitate order and those with incomplete data of EDMEWS, acute physiology and chronic health evaluation (APACHE) II score, or survival information (7-day and 30-day mortality) were excluded. The trends in EDMEWS were determined using the regression line of multiple MEWS measured during ED stay, in which EDMEWS trend progression was defined as the slope of the regression line > zero. The relationship between EDMEWS trend and prognosis was assessed using univariate and multivariate analyses (multiple logistic regression analysis). RESULTS: Of the 1423 selected patients, 499 (35.1%) had worsening 24-h APACHE II score, 110 (7.7%) died within 7 days, and 233 (16.4%) died within 30 days. Factors that were significantly associated with worsening 24-h APACHE II score, 7-day mortality, and 30-day mortality in univariate analysis were selected for inclusion into multiple logistic regression analyses. After adjusting for other covariates, EDMEWS trend progression was significantly associated with 24-h APACHE II score progression, 7-day mortality, and 30-day mortality. CONCLUSIONS: EDMEWS trend progression was significantly associated with 24-h APACHE II score progression, 7-day mortality, and 30-day mortality in elderly ED patients admitted to the ICU. EDMEWS is a simple and useful tool for precisely monitoring patients' ongoing condition and predicting prognosis.

Baicalein Rescues Delayed Cooling via Preservation of Akt Activation and Akt-Mediated Phospholamban Phosphorylation.

Cooling reduces the ischemia/reperfusion (I/R) injury seen in sudden cardiac arrest (SCA) by decreasing the burst of reactive oxygen species (ROS). Its cardioprotection is diminished when delay in reaching the target temperature occurs. Baicalein, a flavonoid derived from the root of ScutellariabaicalensisGeorgi, possesses antioxidant properties. Therefore, we hypothesized that baicalein can rescue cooling cardioprotection when cooling is delayed. Two murine cardiomyocyte models, an I/R model (90 min ischemia/3 h reperfusion) and stunning model (30 min ischemia/90 min reperfusion), were used to assess cell survival and contractility, respectively. Cooling (32 °C) was initiated either during ischemia or during reperfusion. Cell viability and ROS generation were measured. Cell contractility was evaluated by real-time phase-contrast imaging. Our results showed that cooling reduced cell death and ROS generation, and this effect was diminished when cooling was delayed. Baicalein (25 µM), given either at the start of reperfusion or start of cooling, resulted in a comparable reduction of cell death and ROS production. Baicalein improved phospholamban phosphorylation, contractility recovery, and cell survival. These effects were Akt-dependent. In addition, no synergistic effect was observed with the combined treatments of cooling and baicalein. Our data suggest that baicalein may serve as a novel adjunct therapeutic strategy for SCA resuscitation.

Emergency department DNR order in patients with spontaneous intracerebral hemorrhage.

OBJECTIVES: To explore the determinant factors and prognostic significance of emergency department do-not-resuscitate (ED-DNR) orders for patients with spontaneous intracerebral hemorrhage (SICH). METHODS: Consecutive adult SICH patients treated in our ED from January 1, 2012 to December 31, 2016 were selected as the eligible cases from our hospital's stroke database. Patients' information was comprehensively reviewed from the database and medical and nursing charts. ED-DNR orders were defined as DNR orders written during ED stay. Multiple logistic regression analysis was used to identify significant determinants of ED-DNR orders. Thirty- and 90-day neurological outcomes were analyzed to test the prognosis impact of ED-DNR orders. RESULTS: Among 835 enrolled patients, 112 (12.1%) had ED-DNR orders. Significant determinant factors of ED-DNR orders were age, ambulatory status before the event, brain computed tomography findings of midline shift, intraventricular extension, larger hematoma size, and ED arrival GCS ≤8. Patients with and without ED-DNR orders had a similar 30-day death rate if they had the same initial ICH score point. During 30 to 90days, patients with ED-DNR orders had a significantly increased mortality rate. However, the rate of improvement in neurological status between the two groups was not significantly different. CONCLUSIONS: Older and sicker SICH patients had higher rate of ED-DNR orders. The mortality rates between patients with and without ED-DNR orders for each ICH score point were not significantly different. During the 30-to-90-day follow-up, the rates of neurological improvement in both groups were similar.

Interhospital transfer neurological deterioration in patients with spontaneous intracerebral haemorrhage: incidence and risk factors.

OBJECTIVE: To explore the incidence and risk factors for interhospital transfer neurological deterioration (IHTND) in patients with spontaneous intracerebral haemorrhage (SICH). METHODS: Consecutive adult patients with first-ever SICH referred to our emergency department (ED) and transported by ambulance from July 2011 through June 2015 were eligible for this prospective observational study. Enrolled patients had SICH with elapsed time <12 hours and a nearly normal Glasgow Coma Scale (GCS) score (≥13) at presentation. IHTND was defined as GCS score drop ≥2 points during the time from last GCS measure in first ED (shortly before transport) and first measure in second ED (shortly after arrival), which was confirmed by the accompanying nurse practitioner. The potential risk factors for IHTND were screened by χ2 test, unpaired t test (parametric data) or Mann-Whitney U test (non-parametric data) in univariate analysis. Multiple logistic regression analysis was used to adjust for other covariates. RESULTS: Among 217 enrolled patients, 36 (16.6%) had IHTND. After adjustment for other covariates in multiple logistic regression analysis, the significant predictors of IHTND were arrival systolic blood pressure ≥180 mm Hg (p=0.026, OR=2.741, 95% CI 1.126 to 6.674), infratentorial ICH (p=0.015, OR=3.182, 95% CI 1.248 to 8.113), presence of intraventricular haemorrhage (p=0.023, OR=2.533, 95% CI 1.137 to 5.645) and larger ICH (by 1 mL increment of haematoma, p=0.013, OR=1.027, 95% CI 1.006 to 1.048). CONCLUSIONS: About one-sixth of referred not comatose patients with SICH developed IHTND. Some risk factors were identified for the first time. Modifying procedures for proper transfer of patients at high-risk for IHTND might help in safely transferring patients with SICH.

Brief left ventricular pressure overload reduces myocardial apoptosis.

BACKGROUND: Both apoptosis and necrosis contribute to cell death after myocardial ischemia and reperfusion. We previously reported that brief left ventricular pressure overload (LVPO) decreased myocardial infarct (MI) size. In this study, we investigated whether brief pressure overload reduces apoptosis and the mechanisms involved. MATERIALS AND METHODS: MI was induced by a 40-min occlusion of the left anterior descending coronary artery and 3-h reperfusion in male anesthetized Sprague-Dawley rats. Brief LVPO was achieved by two 10-min partial snarings of the ascending aorta, raising the systolic left ventricular pressure 50% above the baseline value. Ischemic preconditioning was elicited by two 10-min coronary artery occlusions and 10-min reperfusions. RESULTS: Brief LVPO and ischemic preconditioning significantly decreased MI size (P < 0.001). Brief pressure overload significantly reduced myocardial apoptosis, as evidenced by the decrease in the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling-positive nuclei (P < 0.001), little or no DNA laddering, and reduced caspase-3 activation (P < 0.01). Moreover, brief pressure overload significantly increased Bcl-2 (P < 0.001) and decreased Bax (P < 0.001) and p53 (P < 0.01). Akt phosphorylation was significantly increased by brief pressure overload (P < 0.001), whereas c-Jun N-terminal kinase phosphorylation was significantly decreased (P < 0.001). Hemodynamics, area at risk, and mortality did not differ significantly among groups. CONCLUSIONS: Brief left LVPO significantly reduces myocardial apoptosis. The underlying mechanisms might be related to modulation of Bcl-2 and Bax, inhibition of p53, increased Akt phosphorylation, and suppressed c-Jun N-terminal kinase phosphorylation.

The association between on-scene blood pressure and early neurological deterioration in patients with spontaneous intracerebral haemorrhage.

OBJECTIVE: To determine whether on-scene BP is associated with early neurological deterioration (END) in patients with spontaneous intracerebral haemorrhage (SICH). METHODS: This retrospective cohort study enrolled consecutive ambulance-transported adult SICH patients treated at our emergency department (ED) from January 2007 through December 2012. END was defined as a ≥2-point decrease in GCS within 24 h of ED arrival. The exact relationship between on-scene BP and END was assessed using multiple logistic regression analyses for adjusting age, gender, Charlson Index, aspirin use, smoking, elapsed time, consciousness level on ED arrival, haematoma size, intraventricular extension, midline shift and infratentorial ICH. We further calculated the -2 log-likelihood decrease for each regression model incorporated with the BP values measured at different times to compare model fitness. RESULTS: After adjusting for the covariates, on-scene systolic BP (by 10 mm Hg incremental: OR = 1.126, 95% CI 1.015 to 1.265), diastolic BP (by 10 mm Hg incremental: OR=1.146, 95% CI 1.019 to 1.303) and mean arterial pressure (MAP) (by 10 mm Hg incremental: OR=1.225, 95% CI 1.057 to 1.443) were significantly associated with END; adding on-scene MAP into the regression model yielded the highest model fitness increase. Adding on-scene BPs into the regression model yielded higher model fitness increase than adding ED and admission BPs. CONCLUSIONS: Few on-scene BP indices were associated with neuroworsening within 24 h after ED arrival in non-comatose SICH patients. Compared with BP measured on ED arrival or admission, on-scene BP had a stronger correlation with END.

Sarcopenia-related changes in serum GLP-1 level affect myogenic differentiation.

BACKGROUND: Sarcopenia, a group of muscle-related disorders, leads to the gradual decline and weakening of skeletal muscle over time. Recognizing the pivotal role of gastrointestinal conditions in maintaining metabolic homeostasis within skeletal muscle, we hypothesize that the effectiveness of the myogenic programme is influenced by the levels of gastrointestinal hormones in the bloodstream, and this connection is associated with the onset of sarcopenia. METHODS: We first categorized 145 individuals from the Emergency Room of Taipei Veterans General Hospital into sarcopenia and non-sarcopenia groups, following the criteria established by the Asian Working Group for Sarcopenia. A thorough examination of specific gastrointestinal hormone levels in plasma was conducted to identify the one most closely associated with sarcopenia. Techniques, including immunofluorescence, western blotting, glucose uptake assays, seahorse real-time cell metabolic analysis, flow cytometry analysis, kinesin-1 activity assays and qPCR analysis, were applied to investigate its impacts and mechanisms on myogenic differentiation. RESULTS: Individuals in the sarcopenia group exhibited elevated plasma levels of glucagon-like peptide 1 (GLP-1) at 1021.5 ± 313.5 pg/mL, in contrast to non-sarcopenic individuals with levels at 351.1 ± 39.0 pg/mL (P < 0.05). Although it is typical for GLP-1 levels to rise post-meal and subsequently drop naturally, detecting higher GLP-1 levels in starving individuals with sarcopenia raised the possibility of GLP-1 influencing myogenic differentiation in skeletal muscle. Further investigation using a cell model revealed that GLP-1 (1, 10 and 100 ng/mL) dose-dependently suppressed the expression of the myogenic marker, impeding myocyte fusion and the formation of polarized myotubes during differentiation. GLP-1 significantly inhibited the activity of the microtubule motor kinesin-1, interfering with the translocation of glucose transporter 4 (GLUT4) to the cell membrane and the dispersion of mitochondria. These impairments subsequently led to a reduction in glucose uptake to 0.81 ± 0.04 fold (P < 0.01) and mitochondrial adenosine triphosphate (ATP) production from 25.24 ± 1.57 pmol/min to 18.83 ± 1.11 pmol/min (P < 0.05). Continuous exposure to GLP-1, even under insulin induction, attenuated the elevated glucose uptake. CONCLUSIONS: The elevated GLP-1 levels observed in individuals with sarcopenia are associated with a reduction in myogenic differentiation. The impact of GLP-1 on both the membrane translocation of GLUT4 and the dispersion of mitochondria significantly hinders glucose uptake and the production of mitochondrial ATP necessary for the myogenic programme. These findings point us towards strategies to establish the muscle-gut axis, particularly in the context of sarcopenia. Additionally, these results present the potential of identifying relevant diagnostic biomarkers.

How to differentiate spontaneous intramural intestinal hemorrhage from acute mesenteric ischemia.

OBJECTS: The purpose of our study was to assess the diagnostic values of laboratory tests to differentiate spontaneous intramural intestinal hemorrhage (SIIH) from acute mesenteric ischemia (AMI) after abdominal computed tomography (CT) survey in the emergency department (ED). METHOD: We retrospectively included 76 patients diagnosed SIIH or AMI after abdominal CT. RESULTS: The mean ages of 28 SIIH patients and 48 AMI patients were 75.9 ± 13.7 years and 75.8 ± 11.6 years, respectively. Patients with SIIH had significantly higher rate of Coumadin use (P < .001) and localized tenderness (P < .05). In laboratory findings, SIIH patients had prolonged prothrombin time (PT) (83.6 ± 30.0 vs. 13.4 ± 3.2, P < .001), lower blood urea nitrogen (P < .05), lower creatinine (P < .05), and lower creatine kinase (P < .05). Prolonged PT showed good discriminative value to differentiate acute abdomen patients with SIIH from AMI after abdominal CT, with an area under the receiver operating characteristic curve of 0.980 (95% confidence interval, 0.918-0.998; P < .0001). Prolonged PT cut-off value of ≧22.5 seconds had a sensitivity of 92.9% and a specificity of 100%. Logistic regression analysis identified prolonged PT as an independent predictor of SIIH (odds ratio, OR, 22.2; P = .007). CONCLUSION: Abdominal pain patients with either SIIH or AMI are rare in the ED, but abdominal CT sometimes cannot help to differentiate them due to similar CT findings. Prolonged PT might help emergency physicians and surgeons differentiate SIIH from AMI in such cases.

Comprehensive Geriatric Assessment in the Emergency Department for Identifying Elderly Individuals at Risk of Hip Fracture.

Background: Hip fracture (HF) is a major challenge for healthcare systems in terms of increased costs and lengths of stay, and it has been estimated that by 2050, half of the projected 6.26 million global HFs will occur in Asia. Owing to the high morbidity and mortality associated with HF in elderly individuals, it is crucial to recognize at-risk elderly patients in the ED so that special precautions and preventive measures can be taken. While comprehensive geriatric assessment (CGA) has been shown to improve outcomes and prevent secondary fractures in elderly individuals with HF in outpatient settings, there is a lack of data to identify elderly Asian patients who are at risk of HF via using CGA in the emergency department (ED). The aim of this study is to identify the characteristics of elderly Asian patients in the ED who have an increased risk of HF via CGA. Methods: A case-control study was conducted in the ED at Taipei Veterans General Hospital, a medical center located in Taipei, Taiwan, from October 2018 to December 2019. Patients > 75 years old with and without HF were compared using data obtained from CGAs conducted by trained nurses. Results: A total of 85 HF patients (cases) and 680 non-HF patients were enrolled, among whom 340 non-HF control individuals (controls) were selected by simple random sampling. HF occurred more frequently in women and in patients with depressive symptoms. An association between decreased handgrip strength and HF risk, especially in men, was also identified ( p = 0.011). The variables independently associated with the presence of HF in the multivariate analysis were female sex (odds ratio [OR]: 2.229; 95% confidence interval [CI]: 1.332-3.728) and decreased handgrip strength (OR: 2.462; 95% CI: 1.155-5.247). Conclusions: By performing CGAs in the ED, we found that female sex and decreased handgrip strength were associated with HF risk. Therefore, we propose that targeted assessment of handgrip strength in female patients aged > 75 years in the ED may identify those at greatest risk of HF, resulting in improved emergency care for geriatric patients.

Geriatric syndromes predict mortality of people aged 75+ years in the observation room of emergency department: Towards function-centric emergency medicine.

BACKGROUND: Aging is a complex process involving functional decline, reduced physiological reserve, increased multimorbidity, and impaired homeostasis, all of which collectively generate various health risks for older adults. To predict short-term mortality of non-critical older patients in the observation room of the emergency department (ED) based on function-centric approach instead of disease-centric one. METHODS: We conducted a prospective study enrolling 831 patients aged 75 years and older between 2018 and 2020. Comprehensive geriatric assessment was performed on all patients, and the results were integrated into the care planning process. RESULTS: In total 831 patients (mean age: 84.8 ± 5.8 years) were enrolled and the post-discharge mortality rate was 3.3% (28 deaths) after 3 months, and 5.4% (45 deaths) after 6 months. The independent predictors of 3-month mortality were malnutrition (adjusted odds ratio [OR], 4.77; p < 0.05), incontinence (adjusted OR, 2.58; p < 0.05) and multimorbidity (adjusted OR, 1.51; p < 0.001). For 6-month mortality, malnutrition (adjusted OR, 4.20; p < 0.01), multimorbidity (adjusted OR, 1.40; p < 0.001) and activities of daily living (adjusted OR, 0.99; p < 0.05) were all independent predictors. CONCLUSION: Although ED aims to treat acute and life-threatening conditions, older persons with geriatric syndromes are also at a substantially high risk of adverse outcomes, even mortality. Transitioning of the ED from disease-centric to function-centric services is important for responding to the changing health care needs of super-aged societies.

Gastric Mobility and Gastrointestinal Hormones in Older Patients with Sarcopenia.

Sarcopenia has serious clinical consequences and poses a major threat to older people. Gastrointestinal environmental factors are believed to be the main cause. The aim of this study was to describe the relationship between sarcopenia and gastric mobility and to investigate the relationship between sarcopenia and the concentration of gastrointestinal hormones in older patients. Patients aged ≥ 75 years were recruited for this prospective study from August 2018 to February 2019 at the emergency department. The enrolled patients were tested for sarcopenia. Gastric emptying scintigraphy was conducted, and laboratory tests for cholecystokinin(CCK), glucagon-like peptide-1 (GLP-1), peptide YY (PYY), nesfatin, and ghrelin were performed during the fasting period. We enrolled 52 patients with mean age of 86.9 years, including 17 (32.7%) patients in the non-sarcopenia group, 17 (32.7%) patients in the pre-sarcopenia group, and 18 (34.6%) in the sarcopenia group. The mean gastric emptying half-time had no significant difference among three groups. The sarcopenia group had significantly higher fasting plasma concentrations of CCK, GLP-1, and PYY. We concluded that the older people with sarcopenia had significantly higher plasma concentrations of CCK, GLP-1, and PYY. In the elderly population, anorexigenic gastrointestinal hormones might have more important relationships with sarcopenia than orexigenic gastrointestinal hormones.

Change of plasma amylin after bariatric surgery challenged by oral glucose is associated with remission of type 2 diabetes mellitus.

BACKGROUND: Gastric bypass (GB) and sleeve gastrectomy (SG) were found to achieve different remission rates in the treatment of type 2 diabetes (T2DM). The alteration in several gut hormones after bariatric surgery has been demonstrated to play a key role for T2DM remission. Nevertheless, amylin, one of the diabetes-associated peptides, so far has an undetermined position on T2DM remission after bariatric surgery. METHODS: Sixty eligible patients with T2DM (GB, 30; SG, 30) were initially enrolled in the hospital-based randomized trial. Twenty patients (GB, 10; SG, 10) who met the inclusion criteria and agreed to undergo 75-g oral glucose tolerance test (OGTT) were recruited. The recruited subjects underwent anthropometric measurements, routine laboratory tests, and 75-g OGTT before and 1 year after bariatric surgery. Enzyme immunoassays for plasma amylin were analyzed. RESULTS: All subjects that underwent GB and half of those who underwent SG achieved T2DM remission. Plasma amylin levels significantly decreased 60-90 min after OGTT in the GB group (p < 0.05) and 30-60 minutes after OGTT in the SG group (p < 0.05). Significantly decreased plasma amylin levels were observed at 30-90 minutes after OGTT in the noncomplete remitters of the GB group (p < 0.05). Plasma amylin levels initially increased (p < 0.05) within 30 minutes after OGTT and then decreased (p < 0.05) in the next 30-minute interval in the nonremitters of the SG group. CONCLUSION: Postoral glucose challenge amylin levels could be as one of the parameters to evaluate T2DM remission after bariatric surgery, especially in those after SG.

Differences in Characteristics, Hospital Care, and Outcomes between Acute Critically Ill Emergency Department Patients Receiving Palliative Care and Usual Care.

BACKGROUND: The early integration of palliative care in the emergency department (ED-PC) provides several benefits, including improved quality of life with optimal comfort measures, and symptom control. Whether palliative care could affect the intensive care unit admissions, hospital care and resource utilization requires further investigation. AIM: To determine the differences in inpatient characteristics, hospital care, survival, and resource utilization between patients receiving palliative care (ED-PC) and usual care (UC). DESIGN: Retrospective observational study. SETTING/PARTICIPANTS: We enrolled consecutive, acute, critically ill patients admitted to the emergency intensive care unit at Taipei Veterans General Hospital from 1 February 2018 to 31 January 2020. RESULTS: A total of 1273 patients were evaluated for unmet palliative care needs; 685 patients received ED-PC and 588 received UC. The palliative care patients were more severely frail (AOR 2.217 (1.295-3.797), p = 0.004), had functional deterioration with three ADLs (AOR 1.348 (1.040-1.748), p = 0.024), biopsychosocial discomfort (AOR 1.696 (1.315-2.187), p < 0.001), higher Taiwan Triage and Acuity Scale 1 (p = 0.024), higher in-hospital mortality (AOR 1.983 (1.540-2.555), p < 0.001), were four times more likely to sign an DNR (AOR 4.536 (2.522-8.158), p < 0.001), and were twice as likely to sign an DNR at admission (AOR 2.1331.619-2.811), p < 0.001). Palliative care patients received less epinephrine (AOR 0.424 (0.265-0.678), p < 0.001), more frequent withdrawal of an endotracheal tube (AOR 8.780 (1.122-68.720), p = 0.038), and more narcotics (AOR1.675 (1.132-2.477), p = 0.010). Palliative care patients exhibited lower 7-day, 30-day, and 90-day survival rates (p < 0.001). There was no significant difference in the hospital length of stay (LOS) (21.2 ± 26.6 vs. 21.7 ± 20.6, p = 0.709) nor total hospital expenses (293,169 ± 350,043 vs. 294,161 ± 315,275, p = 0.958). CONCLUSION: Acute critically ill patients receiving palliative care were more frail, more critical, and had higher in-hospital mortality. Palliative care patients received less epinephrine, more endotracheal extubation, and more narcotics. There was no difference in the hospital LOS or hospital costs between the palliative and usual care groups. The synthesis of ED-PC is new but achievable with potential benefits to align care with patient goals.

Differences in Characteristics, Hospital Care and Outcomes between Acute Critically Ill Emergency Department Patients with Early and Late Do-Not-Resuscitate Orders.

Background: A do-not-resuscitate (DNR) order is associated with an increased risk of death among emergency department (ED) patients. Little is known about patient characteristics, hospital care, and outcomes associated with the timing of the DNR order. Aim: Determine patient characteristics, hospital care, survival, and resource utilization between patients with early DNR (EDNR: signed within 24 h of ED presentation) and late DNR orders. Design: Retrospective observational study. Setting/Participants: We enrolled consecutive, acute, critically ill patients admitted to the emergency intensive care unit (EICU) at Taipei Veterans General Hospital from 1 February 2018, to 31 January 2020. Results: Of the 1064 patients admitted to the EICU, 619 (58.2%) had EDNR and 445 (41.8%) LDNR. EDNR predictors were age >85 years (adjusted odd ratios (AOR) 1.700, 1.027-2.814), living in long-term care facilities (AOR 1.880, 1.066-3.319), having advanced cardiovascular diseases (AOR 2.128, 1.039-4.358), "medical staff would not be surprised if the patient died within 12 months" (AOR 1.725, 1.193-2.496), and patients' family requesting palliative care (AOR 2.420, 1.187-4.935). EDNR patients underwent lesser endotracheal tube (ET) intubation (15.6% vs. 39.9%, p < 0.001) and had reduced epinephrine injection (19.9% vs. 30.3%, p = 0.009), ventilator support (16.7% vs. 37.9%, p < 0.001), and narcotic use (51.1% vs. 62.6%, p = 0.012). EDNR patients had significantly lower 7-day (p < 0.001), 30-day (p < 0.001), and 90-day (p = 0.023) survival. Conclusions: EDNR patients underwent decreased ET intubation and had reduced epinephrine injection, ventilator support, and narcotic use during EOL as well as decreased length of hospital stay, hospital expenditure, and survival compared to LDNR patients.

Differences in end-of-life care and outcomes in palliative consultation-eligible patients with and without do-not-resuscitate orders: A propensity score-matched study.

BACKGROUND: The primary objective of palliative care, not synonymous with end-of-life (EOL) care, is to align care plans with patient goals, regardless of whether these goals include the pursuit of invasive, life-sustaining procedures, or not. This study determines the differences in EOL care, resource utilization, and outcome in palliative care consultation-eligible emergency department patients with and without do-not-resuscitate (DNR) orders. METHODS: This is a retrospective observational study. We consecutively enrolled all the acutely and critically ill emergency department patients eligible for palliative care consultation at the Taipei Veterans General Hospital, a 3000-bed tertiary hospital, from February 1 to July 31, 2018. The outcome measures included in-hospital mortality and EOL care of patients with and without DNR. RESULTS: A total of 396 patients were included: 159 with and 237 without DNR. Propensity score matching revealed that patients with DNR had significantly shorter duration of hospital stay (404.4 ± 344.4 hours vs 505.2 ± 498.1 hours; p = 0.037), higher in-hospital mortality (54.1% vs 34.6%; p < 0.001), and lower total hospital expenditure (191 239 ± 177 962 NTD vs 249 194 ± 305 629 NTD; p = 0.04). Among patients with DNR, there were fewer deaths in the intensive care unit (30.2% vs 37.0%), more deaths in the hospice ward (16.3% vs 7.4%), more critical discharge to home (9.3% vs 7.4%), more endotracheal removals (3.1% vs 0%; p = 0.024), and more narcotics use (32.7% vs 22.1%; p = 0.018). CONCLUSION: The palliative care consultation-eligible emergency department patients with DNR compared with those without DNR experienced worse outcomes, greater pain control, more endotracheal extubations, shorter duration of hospital stay, more critical discharge to home, more hospice referrals, and 23.3% reduction in total expenditure. There were fewer deaths in the ICU among them as well.

Emergency Department Referral for Hospice and Palliative Care Differs among Patients with Different End-of-Life Trajectories: A Retrospective Cohort Study.

Emergency units have been gradually recognized as important settings for palliative care initiation, but require precise palliative care assessments. Patients with different illness trajectories are found to differ in palliative care referrals outside emergency unit settings. Understanding how illness trajectories associate with patient traits in the emergency department may aid assessment of palliative care needs. This study aims to investigate the timing and acceptance of palliative referral in the emergency department among patients with different end-of-life trajectories. Participants were classified into three end-of-life trajectories (terminal, frailty, organ failure). Timing of referral was determined by the interval between the date of referral and the date of death, and acceptance of palliative care was recorded among participants eligible for palliative care. Terminal patients had the highest acceptance of palliative care (61.4%), followed by those with organ failure (53.4%) and patients with frailty (50.1%) (p = 0.003). Terminal patients were more susceptible to late and very late referrals (47.4% and 27.1%, respectively) than those with frailty (34.0%, 21.2%) and with organ failure (30.1%, 18.8%) (p < 0.001, p = 0.022). In summary, patients with different end-of-life trajectories display different palliative care referral and acceptance patterns. Acknowledgement of these characteristics may improve palliative care practice in the emergency department.
