RESUMO
This retrospective study assessed the effectiveness and impact of implementing a Modified Early Warning System (MEWS) and Rapid Response Team (RRT) for inpatients admitted to the general ward (GW) of a medical center. This study included all inpatients who stayed in GWs from Jan. 2017 to Feb. 2022. We divided inpatients into GWnon-MEWS and GWMEWS groups according to MEWS and RRT implementation in Aug. 2019. The primary outcome, unexpected deterioration, was defined by unplanned admission to intensive care units. We defined the detection performance and effectiveness of MEWS according to if a warning occurred within 24 h before the unplanned ICU admission. There were 129,039 inpatients included in this study, comprising 58,106 GWnon-MEWS and 71,023 GWMEWS. The numbers of inpatients who underwent an unplanned ICU admission in GWnon-MEWS and GWMEWS were 488 (.84%) and 468 (.66%), respectively, indicating that the implementation significantly reduced unexpected deterioration (p < .0001). Besides, 1,551,525 times MEWS assessments were executed for the GWMEWS. The sensitivity, specificity, positive predicted value, and negative predicted value of the MEWS were 29.9%, 98.7%, 7.09%, and 99.76%, respectively. A total of 1,568 warning signs accurately occurred within the 24 h before an unplanned ICU admission. Among them, 428 (27.3%) met the criteria for automatically calling RRT, and 1,140 signs necessitated the nursing staff to decide if they needed to call RRT. Implementing MEWS and RRT increases nursing staff's monitoring and interventions and reduces unplanned ICU admissions.

BACKGROUND: Hip hemiarthroplasty (HHA) is a common treatment for hip fractures in the elderly population. Because of the fatal effects of bone cement implantation syndrome, the safety of cement utilization to enhance implant firmness in the femur is controversial. The aim of this study was to investigate the postoperative survival of elderly patients receiving HHA with and without cement fixation. METHODS: Claim data from the National Health Insurance Database and the National Register of Deaths Database were used for analysis in this retrospective cohort study. From 2008 to 2014, 25,862 patients aged 80 years or older treated with hip hemiarthroplasty were included in the analysis. A Cox proportional risk model was used to analyse the effects of cement utilization on postoperative mortality. RESULTS: The cemented group had a significantly higher mortality risk than the non-cemented group within 7, 30, 180 days and 1 year after the operation. The effect of bone cement on postoperative mortality was significantly stronger within 7 days than within 30, 180 days and 1 year. In addition, the male gender, age > 85 years and higher score on the Charlson Comorbidity Index were also risk factors for mortality (p < 0.05). Patients who received HHA in lower-volume hospitals had higher mortality rates within 180 days and 1 year than those in higher-volume hospitals. Compared with patients who were operated on by high-volume surgeons, those who received surgery performed by lower-volume surgeons were more likely to die within 30 days (aHR = 1.22), 180 days (aHR = 1.16) and 1 year (aHR = 1.19), respectively. CONCLUSIONS: The postoperative mortality rate of elderly patients undergoing HHA was significantly higher in the cemented group than in the non-cemented group.

BACKGROUND: Several medical conditions that mimic ST-elevation myocardial infarction (STEMI) have been reported previously, but acute abdominal disease mimicking STEMI is rare. CASE REPORT: We report on a 72-year-old man who presented to the emergency department (ED) with epigastric pain. Meanwhile, STEMI with shock developed. Anticoagulation medication and emergent percutaneous coronary intervention (PCI) were arranged in a timely manner. However, hepatocellular carcinoma (HCC) rupture was the true cause of the ST-segment elevation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report highlights the fact that acute myocardial infarction is not the only cause of ST-segment elevation. HCC rupture should be one of the differential diagnoses.

Chronic kidney disease (CKD) is a multifactorial, complex condition that requires proper management to slow its progression. In Thailand, 11.6 million people (17.5%) have CKD, with 5.7 million (8.6%) in the advanced stages and >100,000 requiring hemodialysis (2020 report). This study aimed to develop a risk prediction model for CKD in Thailand. Data from 17,100 patients were collected to screen for 14 independent variables selected as risk factors, using the IBK, Random Tree, Decision Table, J48, and Random Forest models to train the predictive models. In addition, we address the unbalanced category issue using the synthetic minority oversampling technique (SMOTE). The indicators of performance include classification accuracy, sensitivity, specificity, and precision. This study achieved an accuracy rate of 92.1% with the top-performing Random Forest model. Moreover, our empirical findings substantiate previous research through highlighting the significance of serum albumin, blood urea nitrogen, age, direct bilirubin, and glucose. Furthermore, this study used the SHapley Additive exPlanations approach to analyze the attributes of the top six critical factors and then extended the comparison to include dual-attribute factors. Finally, our proposed machine learning technique can be used to evaluate the effectiveness of these risk factors and assist in the development of future personalized treatment.
RESUMO
BACKGROUND/PURPOSE: An intubating laryngeal mask airway (ILMA) is an alternative device for airway control, capable of providing effective ventilation in various situations. The purpose of this study is to compare the effects of the ILMA and bag-valve-mask (BVM) ventilation devices on out-of-hospital cardiac arrest (OHCA) patients. METHODS: An ILMA training course was conducted by emergency medical technicians (EMTs). Before training, OHCA patients had received BVM ventilation; these patients were defined as the BVM group. After training, all EMTs in the area being served were instructed to immediately use an ILMA on OHCA patients when possible; these patients were defined as the ILMA group. Demographics, transport time, first arterial blood gas data, and the short-term outcomes of these two groups were analyzed. RESULTS: A total of 398 OHCA patients (89 in the BVM group and 309 in the ILMA group) were analyzed. All of the EMTs passed the training course, and ILMAs were used in the emergency settings. The ILMA was applied to each OHCA patient for a longer-than-average field time than the BVM (9.5 vs. 7.8 minutes, p = 0.006). The 24-hour survival rate of the ILMA-treated patients was significantly higher than BVM-treated patients (36.2% vs. 24.7%, p = 0.033). CONCLUSION: Well-trained EMTs were able to insert the ILMA and ventilate OHCA patients properly in prehospital settings, and ILMA-treated OHCA patients had better short-term outcomes than BVM-treated patients.

With a collectivist cultural perspective, we examined the positive effects of employees' perceptions of a familial climate on loyalty to supervisors, the mediation of loyalty between perception of a familial climate and job performance, and the moderation of employees' filial behaviour on the relationship between perception of a familial climate and loyalty. The participants consisted of 247 supervisor-and-subordinate dyads in Taiwan. The results supported our hypotheses. Through the mechanisms of family behaviour transference, social identification and supervisor-subordinate exchange, perception of an organizational familial climate enhanced loyalty to supervisors. Furthermore, loyalty to supervisors mediated the relationship between perception of a familial climate and job performance. Filial behaviour moderated the relationship between perception of a familial climate and loyalty; thus, the relationship of perception of a familial climate and loyalty was stronger for employees with low levels of filial behaviour and weaker for employees with high levels of filial behaviour. These findings are discussed in terms of their theoretical and practical implications for future research and management practices.

Background/purpose: Life expectancy (LE) is a hypothetical measure to predict life longevity and the indicator of society's overall health. Tooth loss is a worldwide enigma; however, the LE for tooth (LET) are obscure. LET and the burden of tooth loss in Taiwan were estimated using the scheme of National Health Insurance (NHI). Materials and methods: Using NHI data, mortality rate, age-specific mortality rate, tooth-extraction rate, and age-specific tooth-extraction rate (ASTER) of Taiwanese in 2004 and 2013 were estimated. ASTER for the individual tooth (ASTER-T) was analyzed for each of 28 permanent teeth according to ID code and tooth location. LET and years lived with disability for tooth loss (YLDs-T) of each permanent tooth were estimated following Global Burden Disease study. Results: In 2004, 1,741,228 teeth extracted from 1,078,254 patients among 22,646,835 Taiwanese, whereas 2,012,907 teeth extracted from 1,254,746 patients among 23,344,670 in 2013. In both years, the ASTERs presented an increasing trend as age increased. However, the ASTER-Ts presented varied according to tooth types. The LET and YLDs-T were also varied. The maximum values of YLDs-T were noticed for the first molars. Conclusion: Our findings of this national survey highlight the need for public health policy, particular the early loss of first molars, aiming to increase awareness regarding oral health.
RESUMO
The induction of oxidative stress and inflammation has been closely linked in traumatic brain injury (TBI). Transcriptional factors of signal transducers and activators of transcription (STAT) proteins are redox sensitive and participate in the regulation of cytokine signaling. Previous studies demonstrated that melatonin protects neurons through its antioxidative and anti-inflammatory effects in various neuropathological conditions. However, the effect of melatonin on STAT activity after TBI has not yet been explored. In this study, we used a controlled weight-drop TBI model and found that brain contusion induced oxidative stress (a decreased level of total glutathione and an increased ratio of oxidized glutathione to total glutathione), a reduction in STAT1 DNA-binding activity, and consequently neuronal loss in a contusion depth-dependent manner. A significant increased mRNA expression of suppressor of cytokine signaling (SOCS3), inducible nitric oxide synthetase (iNOS), and interleukine-6 (IL-6), but a decreased protein expression of protein inhibitor of activated STAT (PIAS1), was found 24 hr after brain contusion. SOCS3 and PIAS1 are endogenous negative regulators of STAT1. Moreover, the combination of intraperitoneal and local (presoaked in gelfoam and placed on the traumatic cortex) administration of melatonin had the most pronounced influence in inhibiting all effects except the PIAS1 downregulation induced by brain contusion. The results suggest that SOCS-3 upregulation and oxidative stress may contribute to the STAT1 inactivation after TBI. Melatonin protects neurons from TBI by reducing oxidative stress, STAT1 inactivation, and upregulation of SOCS-3 and pro-inflammatory cytokines.

Methamphetamine abuse is getting worse amongst the younger population. While there is methadone or buprenorphine harm-reduction treatment for heroin addicts, there is no drug treatment for addicts with methamphetamine use disorder (MUD). Recently, non-medication treatment, such as the cue-elicited craving method integrated with biofeedback, has been widely used. Further, virtual reality (VR) is proposed to simulate an immersive virtual environment for cue-elicited craving in therapy. In this study, we developed a VR system equipped with flavor simulation for the purpose of inducing cravings for MUD patients in therapy. The VR system was integrated with multi-model sensors, such as an electrocardiogram (ECG), galvanic skin response (GSR) and eye tracking to measure various physiological responses from MUD patients in the virtual environment. The goal of the study was to validate the effectiveness of the proposed VR system in inducing the craving of MUD patients via the physiological data. Clinical trials were performed with 20 MUD patients and 11 healthy subjects. VR stimulation was applied to each subject and the physiological data was measured at the time of pre-VR stimulation and post-VR stimulation. A variety of features were extracted from the raw data of heart rate variability (HRV), GSR and eye tracking. The results of statistical analysis found that quite a few features of HRV, GSR and eye tracking had significant differences between pre-VR stimulation and post-VR stimulation in MUD patients but not in healthy subjects. Also, the data of post-VR stimulation showed a significant difference between MUD patients and healthy subjects. Correlation analysis was made and several features between HRV and GSR were found to be correlated. Further, several machine learning methods were applied and showed that the classification accuracy between MUD and healthy subjects at post-VR stimulation attained to 89.8%. In conclusion, the proposed VR system was validated to effectively induce the drug craving in MUD patients.

BACKGROUND: Little is known about the characteristics of patients needing palliative care consultation in the emergency department (ED). This study aimed to investigate the impacts of initiating screening in acute critically ill patients needing palliative care on mortality, health care resources, and end-of-life (EOL) care in the intensive care unit in ED (EICU). METHODS: We conducted an analysis study in Taipei Veterans General Hospital. From February 1 to July 31, 2018, acute critically ill patients in EICU were recruited. The primary outcomes were inhospital mortality and EOL care. The secondary outcomes included clinical characteristics and health care utilization. RESULTS: A total of 796 patients were screened, with 396 eligible and 400 noneligible patients needing palliative care consultations. The mean age was 74.8 ± 17.1 years, and 62.6% of the patients were male. According to logistic regression analysis, clinical predictors, including age (adjusted odds ratio [AOR], 1.028; 95% CI, 1.015-1.042), respiratory distress and/or respiratory failure (AOR, 2.670; 95% CI, 1.829-3.897), the Acute Physiology and Chronic Health Evaluation II score (AOR, 1.036; 95% CI, 1.009-1.064), Charlson Comorbidity Index score (AOR, 1.212; 95% CI, 1.125-1.306), and Glasgow Coma Scale (AOR, 0.843; 95% CI, 0.802-0.885), were statistically more significant in eligible patients than in noneligible patients. The inhospital mortality rate was significantly higher in eligible patients than that in noneligible patients (40.7% vs 11.5%, p < 0.01). Eligible patients have a higher ratio in both vasopressor and narcotic use and withdrawal of endotracheal tube than noneligible patients (p < 0.05). CONCLUSION: Our study results demonstrated that initiating palliative consultation for acute critically ill patients in ED had an impact on the utilization of health care resources and quality of EOL care. Further assessments of the viewpoints of ED patients and their family on palliative care consultations and hospice care are required.

RATIONALE: Anxiety is a mediator for emotional reactivity and acute blood pressure elevations, which are associated with an increased risk of cardiovascular death. Alprazolam is a common medication for anxiolysis. We hypothesized that alprazolam usage can reduce the risk of major adverse cardiovascular events (MACEs) in patients with hypertension. METHODS: A retrospective cohort study was performed using datasets from Taiwanese Health and Welfare Data. Patients with hypertension were divided into exposed (Alprazolam-exposed) and control groups (non-Alprazolam-exposed) with 1:1 propensity score matching. The study endpoint was the occurrence of MACE. Adjusted hazard ratio (aHR) of MACE risk was estimated using the multiple Cox proportional hazard model. Age-stratified analysis was performed to evaluate the interaction of age and alprazolam use with MACEs. RESULTS: The study cohort consisted of 335 517 alprazolam-exposed patients and 1:1 PSM controls. The mean age was 63.62 ± 12.71 years in the Alprazolam-exposed population. Alprazolam exposure was significantly associated with reduced risk of MACEs (aHR = 0.965, 95% CI = 0.954-0.977), including ischemic stroke (aHR = 0.958, 95% CI = 0.940-0.976), hemorrhagic stroke (aHR = 0.856, 95% CI = 0.821-0.892), myocardial infarction (aHR = 0.933, 95% CI = 0.900-0.968), sudden cardiac death (aHR = 0.955, 95% CI = 0.916-0.996), and all-cause mortality (aHR = 0.921, 95% CI = 0.909-0.932). In the age-subgroup analysis, alprazolam showed the greatest risk reduction effect in hemorrhagic stroke for patients aged <65 years (aHR = 0.779, 95% CI = 0.727-0.835). CONCLUSION: Alprazolam usage in patients with hypertension was associated with a slightly reduced risk of MACEs and all-cause mortality, and up to 22% reduced risk of hemorrhagic stroke was observed in alprazolam users aged <65 years.

The synthesis, characterization, and transformation of the anionic {Fe(NO)(2)}(9) dinitrosyl iron complexes (DNICs) [(NO)(2)Fe(ONO)(2)](-) (1), [(NO)(2)Fe(OPh)(2)](-) (2), [(NO)(2)Fe(OPh)(C(3)H(3)N(2))](-) (3) (C(3)H(3)N(2) = imidazolate), [(NO)(2)Fe(OPh)(-SC(4)H(3)S)](-) (4), [(NO)(2)Fe(p-OPhF)(2)](-) (5), and [(NO)(2)Fe(SPh)(ONO)](-) (6) were investigated. The binding affinity of ligands ([SPh](-), [-SC(4)H(3)S](-), [C(3)H(3)N(2)](-), [OPh](-), and [NO(2)](-)) toward the {Fe(NO)(2)}(9) motif follows the ligand-displacement series [SPh](-) approximately [-SC(4)H(3)S](-) > [C(3)H(3)N(2)](-) > [OPh](-) > [NO(2)](-). The findings, the pre-edge energy derived from the 1s --> 3d transition in a distorted T(d) environment of the Fe center falling within the range of 7113.4-7113.8 eV for the anionic {Fe(NO)(2)}(9) DNICs, implicate that the iron metal center of DNICs is tailored to minimize the electronic changes accompanying changes in coordinated ligands. Our results bridging the ligand-substitution reaction study and X-ray absorption spectroscopy study of the electronic richness of the {Fe(NO)(2)}(9) core may point the way to understanding the reasons for nature's choice of combinations of cysteine, histidine, and tyrosine in protein-bound DNICs and rationalize that most DNICs characterized/proposed nowadays are bound to the proteins almost through the thiolate groups of cysteinate/glutathione side chains in biological systems.

Patients with chronic mental illness are highly vulnerable to chronic respiratory problems. We examined the influence of mental disability on respiratory infection-related utilization risk in individuals with and without mental disabilities. A population-based, retrospective cohort design and two-part model were used to analyze respiratory infection-related utilization in individuals with MDs (MD group) and a matched reference group. The respiratory infection-related utilization rate in one year was lower in the MD group (53.8%) than in the reference group (56.6%). The odds ratios (ORs) were significantly higher among individuals with profound MDs (aOR = 1.10; 95% CI 1.07-1.14) and those with a history of dental cavities (aOR = 1.16; 95% CI: 1.13-1.19) or periodontal disease (aOR = 1.22; 95% CI: 1.19-1.26) after controlling for covariables. The average number of visits was higher in the MD group (5.3) than in the reference group (4.0). The respiratory infection-related utilization rate and average number of visits were significantly higher in the mild, moderate and severe disabled groups with a history of periodontal disease, respectively, than that of the reference group. In conclusion, healthcare authorities must develop an incentive program to prevent respiratory infections among individuals with MDs.

Emergency department crowding has been one of the main issues in the health system in Taiwan. Previous studies have usually targeted the process improvement of patient treatment flow due to the difficulty of collecting Emergency Department (ED) staff data. In this study, we have proposed a hybrid model with Discrete Event Simulation, radio frequency identification applications, and activity-relationship diagrams to simulate the nurse movement flows and identify the relationship between different treatment sections. We used the results to formulate four facility layouts. Through comparing four scenarios, the simulation results indicated that 2.2 km of traveling distance or 140 min of traveling time reduction per nurse could be achieved from the best scenario.

Necrotizing fasciitis (NF), a rare but severe infection, usually occurs in individuals with underlying chronic illness, but its clinical presentation among cirrhotic patients is infrequently discussed. Forty-two cirrhotic patients with 47 episodes of NF between 1995 and 2006 were analyzed. Their mean age was 55.6 years, with male preponderance (34 patients, 81%). Lower extremities were mainly involved (70%). Of 42 episodes with identified pathogens, 41 (97%) were monomicrobial infections and were caused mainly by Gram-negative rods (GNBs) (32, 76%), including Vibrio (15, 36%), Klebsiella (9, 21%), and Aeromonas spp. (6, 14%). As compared with NF caused by Gram-positive cocci (GPCs), NF caused by GNBs tended to have concurrent bacteremia (81% versus 50%, P=0.09) and initially presented with septic shock (75% versus 30%, P=0.02). However, the in-hospital mortality rate was similar for NF caused by GNBs and GPCs (34% versus 30%, P=1.00). In multivariate analyses, higher sepsis-related organ failure assessment scores (>8) and Child-Pugh class C at initial presentation were independently associated with poor prognoses.

Hypercalcemia is an uncommon cause of abdominal pain and may be overlooked in the Emergency Department. In this case report, we describe the case of a 48-year-old woman with a prior history of urolithiasis who presented to the Emergency Department with diffuse abdominal pain. She had taken Trichlormethiazide 1 mg daily for her urolithiasis. She was diagnosed with thiazide-related hypercalcemia; hyperparathyroidism and thyroid papillary carcinoma were unveiled during her hospitalization. A thorough history and complete physical examination, paired with appropriate but judicious diagnostic testing, are essential to detecting these unusual causes of abdominal pain.

Fluid resuscitation is vital for treating traumatic hemorrhagic shock (HS), but reperfusion is believed to have the adverse consequences of generating reactive oxygen species and inflammatory cytokines, both of which cause multiple organ dysfunctions. We investigated the effects of various resuscitation fluids on the changes of redox-sensitive molecules after HS and fluid resuscitation (HS/R). We induced HS by bleeding male Sprague-Dawley rats to a blood pressure of 30 to 40 mmHg for 60 minutes. Thirty minutes later, the rats were killed (HS group) or immediately resuscitated with shed blood (HS + BL group), L-isomer lactated Ringer's solution (HS + LR group), or hydroxyethyl starch (HS + HES group). After HS, we found a significant increase in nuclear factor kappaB DNA binding activity, which was effectively inhibited using HES solution or blood resuscitation. Moreover, resuscitation with blood or LR solution, but not HES solution, induced significant oxidative stress, manifested by a high ratio of oxidized glutathione to reduced glutathione in the lungs, liver, and spleen. HS alone, however, did not increase the ratio of the oxidized glutathione to reduced glutathione in all organs. Although the protein expression of anti-apoptotic Bcl-2 and pro-apoptotic Bax varied in different organs, we found that resuscitation using HES solution prevented the HS-induced reduction of the Bcl-2/Bax ratio in the heart. HES solution was an appropriate resuscitation fluid in reversing nuclear factor kappaB activation, maintaining the Bcl-2/Bax ratio, and preventing oxidative stress after acute HS.

BACKGROUND: Slips, trips (STs), and falls are frequent events in childhood. As a child is likely to impact head-first in these events, craniofacial injuries are the most common trauma. We retrospectively surveyed our experience with pediatric craniofacial injuries and investigated the distributions of wound type and injury site, severity, and mechanism. METHODS: A total of 750 children sustaining craniofacial injuries resulting from STs and falls were enrolled in this study. Facial and cranial areas were delimited by an imaginary line extending between the ears and across the eyebrows. Soft-tissue injuries were classified into laceration, contusion, and abrasion. The Glasgow Coma Scale was used to assess the severity of brain injury. RESULTS: Peak incidence of ST-type childhood craniofacial injury occurred at toddler age, whereas falls tended to occur when the children were younger than 1 year old; most of the patients were preschool. The home was the scene for 73% of the STs and 86% of the falls. Lacerations occurred more often in STs (67% vs. 25%), whereas contusions more often resulted from falls (64% vs. 27%). Most of the injuries were to the anterior head with a T-shaped distribution; however, over one third (37%) of the contusions were to the posterior area. Brain injury was absent or only mild in 98% of craniofacial injuries. Falls resulted in a significantly higher incidence of moderate-severe brain injury relative to STs. CONCLUSIONS: Childhood craniofacial injuries resulting from STs are more prevalent than are those that were sustained in falls; however, the latter is associated with greater trauma morbidity. The incidence of childhood craniofacial injury appears to be associated with the level of development irrespective of event type. The home is a potentially dangerous environment for children, especially during the preschool years. Padding the hard, acutely angled surfaces of housing structures and furniture around children's activity zones is an effective method of reducing the risk of childhood craniofacial trauma. Serious or fatal head injuries will rarely occur as the result of a fall from furniture or stairs at home.
