Triage body temperature and its influence on patients with acute myocardial infarction.

BACKGROUND: Fever can occur after acute myocardial infarction (MI). The influence of body temperature (BT) after hospital arrival on patients with acute MI has rarely been investigated. METHODS: Patients who were diagnosed with acute MI in the emergency department (ED) of a tertiary teaching hospital between 1 January 2020 and 31 December 2020 were enrolled. Based on the tympanic temperature obtained at the ED triage, patients were categorized into normothermic (35.5°C-37.5°C), hypothermic (< 35.5°C), or hyperthermic (> 37.5°C) groups. The primary outcome was in-hospital cardiac arrest (IHCA), while the secondary outcomes were adverse events. Statistical significance was set at p < 0.05. RESULTS: There were 440 enrollees; significant differences were found among the normothermic (n = 369, 83.9%), hypothermic (n = 27, 6.1%), and hyperthermic (n = 44, 10.0%) groups in the triage respiratory rate (median [IQR]) (20.0 [4.0] cycles/min versus 20.0 [4.0] versus 20.0 [7.5], p = 0.009), triage heart rate (88.0 [29.0] beats/min versus 82.0 [28.0] versus 102.5 [30.5], p < 0.001), presence of ST-elevation MI (42.0% versus 66.7% versus 31.8%, p = 0.014), need for cardiac catheterization (87.3% versus 85.2% versus 72.7%, p = 0.034), initial troponin T level (165.9 [565.2] ng/L versus 49.1 [202.0] versus 318.8 [2002.0], p = 0.002), peak troponin T level (343.8 [1405.9] ng/L versus 218.7 [2318.2] versus 832.0 [2640.8], p = 0.003), length of ICU stay (2.0 [3.0] days versus 3.0 [8.0] versus 3.0 [9.5], p = 0.006), length of hospital stay (4.0 [4.5] days versus 6.0 [15.0] versus 10.5 [10.8], p < 0.001), and infection during hospitalization (19.8% versus 29.6% versus 63.6%, p < 0.001) but not in IHCA (7.6% versus 14.8% versus 11.4%, p = 0.323) or any adverse events (50.9% versus 48.1% versus 63.6%, p = 0.258). Multivariable analysis showed no significant association of triage BT with IHCA or any major complication. CONCLUSION: Triage BT did not show a significant association with IHCA or adverse events in patients with acute MI. However, triage BT could be associated with different clinical presentations and should warrant further investigation.

A full-face mask for protection against respiratory infections.

BACKGROUND: Aerosols and droplets are the transmission routes of many respiratory infectious diseases. The COVID-19 management guidance recommends against the use of nebulized inhalation therapy directly in the emergency room or in an ambulance to prevent possible viral transmission. The three-dimensional printing method was used to develop an aerosol inhalation treatment mask that can potentially prevent aerosol dispersion. We conducted this utility validation study to understand the practicability of this new nebulizer mask system. RESULTS: The fit test confirmed that the filter can efficiently remove small particles. The different locations of the mask had an excellent fit with a high pressure making a proper face seal usability. The full-face mask appeared to optimize filtration with pressure and is an example of materials that perform well for improvised respiratory protection using this design. The filtering effect test confirmed that the contamination of designated locations could be protected when using the mask with filters. As in the clinical safety test, a total of 18 participants (10 [55.6%] females; aged 33.1 ± 0.6 years) were included in the final analysis. There were no significant changes in SPO2, EtCO2, HR, SBP, DBP, and RR at the beginning, 20th, 40th, or 60th minutes of the test (all p >.05). The discomfort of wearing a mask increased slightly after time but remained within the tolerable range. The vision clarity score did not significantly change during the test. The mask also passed the breathability test. CONCLUSION: The results of our study showed that this mask performed adequately in the fit test, the filtering test, and the clinical safety test. The application of a full-face mask with antiviral properties, together with the newly designed shape of a respirator that respects the natural curves of a human face, will facilitate the production of personal protective equipment with a highly efficient filtration system. METHODS: We conducted three independent tests in this validation study: (1) a fit test to calculate the particle number concentration and its association with potential leakage; (2) a filtering effect test to verify the mask's ability to contain aerosol spread; and (3) a clinical safety test to examine the clinical safety, comfortableness, and visual clarity of the mask.

Adequacy of care during interfacility transfer in Taiwan: A pilot study.

BACKGROUND/PURPOSE: Interfacility transfer (IFT) in Asian communities is seldom discussed. We aimed to describe the characteristics of IFT in Taiwan and to explore the adequacy of care during transfer. METHODS: A retrospective, cross-sectional, descriptive study was conducted using standardized, paper-based interfacility ambulance transfer records between 1 January 2018 and 31 January 2018 from Tainan City, Taiwan. The mode of patient care needed was classified as advanced life support (ALS) or basic life support (BLS) cares based on clinical conditions. ALS providers were defined as physicians and EMT-Paramedics, while BLS providers were defined as nurse practitioners, nurses, EMT-1s and EMT-2s. RESULTS: Of the 377 (227 [60.2%] were >65 years old; 219 [58.1%] were male) IFTs enrolled in the final analysis, 210 (55.7%) patients met the ALS transfer criteria, with poor consciousness (n = 158), tachypnea (n = 17), tachycardia (n = 5), bradycardia (n = 7), hypertension (n = 12), hypotension (n = 13), hypoxia (n = 4), endotracheal intubation (n = 18), a tracheostomy (n = 25), a precipitous labor (n = 1), and after resuscitation for out-of-hospital cardiac arrest (n = 10) or in-hospital cardiac arrest (n = 3). None of the patients who required ALS care had adequate ambulance staffing. Of the 167 BLS IFTs, 9 (5.4%) patients deteriorated and required ALS care during transportation, which included worsened consciousness (n = 2), tachycardia (n = 1), hypertension (n = 2), hypotension (n = 1), and hypoxia (n = 3). The rates of deterioration during BLS-transferals from the emergency departments, general wards, nursing facilities, and unknown areas were 4.8%, 4.7%, 7.7%, and 7.1%, respectively (p = 0.93). CONCLUSION: The patient care during IFT in Taiwan is inadequate currently and should warrant attention.

Predictive performances of ALS and BLS termination of resuscitation rules in out-of-hospital cardiac arrest for different resuscitation protocols.

BACKGROUND: Resuscitation guidance has advanced; however, the predictive performance of the termination of resuscitation (TOR) rule has not been validated for different resuscitation protocols published by the American Heart Association (AHA). METHODS: A retrospective study validating the basic life support (BLS) and advanced life support (ALS) TOR rules was conducted using an Utstein-style database in Tainan city, Taiwan. Adult patients with nontraumatic out-of-hospital cardiac arrests from January 1, 2015, to December 31, 2015, (using the AHA 2010 resuscitation protocol) and from January 1, 2020, to December 31, 2020, (using the AHA 2015 resuscitation protocol) were included. The characteristics of rule performance were calculated, including sensitivity, specificity, positive predictive value (PPV) and negative predictive value. RESULTS: Among 1260 eligible OHCA patients in 2015, 757 met the BLS TOR rule and 124 met the ALS TOR rule. The specificity and PPV for predicting unfavorable neurological outcomes were 61.1% and 99.0%, respectively, for the BLS TOR rule and 93.8% and 99.2%, respectively, for the ALS TOR rule. A total of 970 OHCA patients were enrolled in 2020, of whom 438 met the BLS TOR rule and 104 met the ALS TOR rule. The specificity and PPV for predicting unfavorable neurological outcomes were 85.7% and 100%, respectively, for the BLS TOR rule and 99.5% and 100%, respectively, for the ALS TOR rule. CONCLUSIONS: Both the BLS and ALS TOR rules performed better when using the 2015 AHA resuscitation protocols compared to the 2010 protocols, with increased PPVs and decreased false-positive rates in predicting survival to discharge and good neurological outcomes at discharge. The BLS and ALS TOR rules can perform differently while the resuscitation protocols are updated. As the concepts and practices of resuscitation progress, the BLS and ALS TOR rules should be evaluated and validated accordingly.

The tridimensional personality of male heroin users treated with methadone in Taiwan.

It was our assumption that male heroin users have the personality traits of high impulsivity and low social interaction. Compliance regarding methadone maintenance therapy (MMT) is hypothesized to be related to personality features. We recruited 43 patients that had been receiving MMT and 43 healthy volunteers. All participants completed a Tridimensional Personality Questionnaire (TPQ). Information related to the Opiate Treatment Index (OTI) was gathered from the heroin group. The personality dimensions in the heroin user group and the control group were compared. We further investigated the association between TPQ and OTI. The heroin group presented with lower reward dependence than the control group. Regarding sub-dimensions, heroin users showed higher impulsivity and fatigability, and lower exploratory excitability and social dependence. The explosive (borderline) pattern was more common among the heroin users. The odds ratio of explosive pattern developing to heroin dependence was 4.19. Q scores of heroin use and the maximal methadone dose were associated with persistence.

Psychopathology, rehospitalization and quality of life among patients with schizophrenia under home care case management in Taiwan.

BACKGROUND/PURPOSE: To study the outcome of a group of patients with schizophrenia receiving community home care case management programs by delineating the relationship among their psychopathology, rehospitalization rates and health-related quality of life (HRQoL). METHODS: This is a cross-sectional study on HRQoL, functioning and associating factors and a retrospectivehistorical control study by comparing the frequency and duration of rehospitalization in a sample of 60 patients with schizophrenia under nonintensive case management (non-ICM) in Taiwan. All participants were assessed on the Positive and Negative Syndrome Scale for Schizophrenia (PANSS) for psychopathology, on EuroQoL-5D (EQ-5D) and EQ visual analogue (EQ-VAS) for HRQoL, andGlobal Assessment of Functioning (GAF) for socio-occupational dysfunction. Other clinical characteristics are also gathered. RESULTS: Patients with schizophrenia treated with non-ICM had a significant reduction in admission frequency (-0.10 ± 0.36 times per year, p = 0.042) and length of inpatient stay (-27.8 ± 78.0 days per year, p = 0.008). Better EQ-5D and EQ-VAS are significantly associated with lower general psychopathology score, while better EQ-VAS is significantly associated with older age and higher negative symptoms subscale score. GAF is negatively associated with higher positive symptoms and negative symptoms subscale scores, while positively correlated with a greater reduction in number and frequency of admission. CONCLUSION: Non-ICM can help to decrease rehospitalization of home care patients. HRQoL and functioning can be assessed by the three perspectives we used, and each measure was correlated to different dimensions of patient psychopathology. It will be better if we include baseline and post-intervention PANSS scores, HRQoL and functioning as outcome indicators.

Challenges of Using Instant Communication Technology in the Emergency Department during the COVID-19 Pandemic: A Focus Group Study.

A record outbreak of community-spread COVID-19 started on 10 May 2021, in Taiwan. In response to the COVID-19 pandemic, care facilities have adopted various protocols using instant communication technology (ICT) to provide remote yet timely healthcare while ensuring staff safety. The challenges of patient evaluation in the emergency department (ED) using ICT are seldom discussed in the literature. The objective of this study was to investigate the factors influencing the utility of ICT for patient assessment in emergency settings during the pandemic. The patient flow protocol and the ED layout were modified and regionalized into different areas according to the patient's risk of COVID-19 infection. Nine iPads were stationed in different zones to aid in virtual patient assessment and communication between medical personnel. A focus group study was performed to assess and analyze the utility of the ICT module in the ED. Eight emergency physicians participated in the study. Of them, four (50%) had been directly involved in the development of the ICT module in the study hospital. Three main themes that influenced the application of the ICT module were identified: setting, hardware, and software. The setting theme included six factors: patient evaluation, subspecialty consultation, patient privacy and comfortableness, sanitation, cost, and patient acceptability. The hardware theme included six factors: internet connection, power, quality of image and voice, public or personal mode, portable or fixed mode, and maintenance. The software theme included six factors: platform choices, security, ICT accounts, interview modes, video/voice recording, and time limitation. Future studies should focus on quantifying module feasibility, user satisfaction, and protocol adjustment for different settings.

The role of policies and networks in development of cord blood usage in China.

Research regarding the use of cord blood (CB) has focused on antigen match and the number of stem cells, with policies and networks related to its use being under researched. This article is based on fieldwork in China from 2013 to 2015 and examines ways that the studied CB bank enhances CB usage in China. This article identifies that in addition to finding a match, CB use is linked to the policies and networks, release fee and public awareness that enable CB usage development.

Comparing national home-keeping and the regulation of translational stem cell applications: An international perspective.

A very large grey area exists between translational stem cell research and applications that comply with the ideals of randomised control trials and good laboratory and clinical practice and what is often referred to as snake-oil trade. We identify a discrepancy between international research and ethics regulation and the ways in which regulatory instruments in the stem cell field are developed in practice. We examine this discrepancy using the notion of 'national home-keeping', referring to the way governments articulate international standards and regulation with conflicting demands on local players at home. Identifying particular dimensions of regulatory tools - authority, permissions, space and acceleration - as crucial to national home-keeping in Asia, Europe and the USA, we show how local regulation works to enable development of the field, notwithstanding international (i.e. principally 'western') regulation. Triangulating regulation with empirical data and archival research between 2012 and 2015 has helped us to shed light on how countries and organisations adapt and resist internationally dominant regulation through the manipulation of regulatory tools (contingent upon country size, the state's ability to accumulate resources, healthcare demands, established traditions of scientific governance, and economic and scientific ambitions).

Self-reported psychopathology and health-related quality of life in heroin users treated with methadone.

BACKGROUND: Health-related quality of life (HRQoL) remains poor among heroin users, even after being treated with methadone. Evidence regarding self-reported psychopathology and HRQoL in heroin users is also limited. The present study aimed to investigate the association between self-reported psychopathology and HRQoL in Asian heroin users treated with methadone. METHODS: Thirty-nine heroin users treated with methadone and 39 healthy controls were recruited. Both groups self-reported on demographic data, the Brief Symptom Rating Scale, EuroQoL-5D, and World Health Organization Questionnaire on Quality of Life: Short Form. We compared clinical characteristics, psychopathology, and HRQoL between the two study groups. Correlation and regression analyses were conducted to explore the association between psychopathology and HRQoL in the heroin user group. RESULTS: Heroin users had more psychopathology and worse HRQoL than healthy controls. The HRQoL of heroin users had significant correlations with Brief Symptom Rating Scale scores. HRQoL could be predicted by depression, anxiety, paranoia, and additional symptoms (ie, poor appetite and sleep difficulties) independently. CONCLUSION: Self-reported psychopathology, depression, anxiety, paranoia, poor appetite, and sleep difficulties had a negative impact on each domain of HRQoL among heroin users treated with methadone. The importance of the environmental domain of HRQoL is discussed. Clinicians should recognize comorbid psychiatric symptoms early on to improve HRQoL in heroin users.

Cardiac autonomic modulation during methadone therapy among heroin users: a pilot study.

BACKGROUND: Methadone therapy benefits heroin users in both the medical and psychosocial dimensions. However, both heroin and methadone have cardiac toxicity. Only limited information is available describing the changes in cardiac autonomic function of heroin users and effects of methadone therapy. We conduct the current study to explore the cardiac vagal function in heroin users as well as the impact of lapse and methadone therapy. METHODS: 80 heroin users from a methadone therapy clinic were distributed into 31 compliant and 49 incompliant patients according to whether they lapsed into heroin use within 10 days. 40 healthy control subjects were recruited from the community. Participants underwent electrocardiographic recordings and the heroin users were further investigated before and after methadone therapy. Spectral analysis of heart rate variability (HRV) was computed for cardiac parasympathetic modulation (high-frequency power, HF) and cardiac sympathetic modulation (normalized low-frequency power, LF%). RESULTS: The baseline HRV parameters found lower HF values for heroin users and lower RR interval values for patients with a recent lapse compared with the healthy control subjects. After 1h of methadone administration, heroin users who had lapsed showed a significant increase in HF but the heroin users who had not lapsed did not. CONCLUSION: Our findings suggest that heroin users show decreased cardiac vagal activity and that methadone therapy immediately facilitates vagal regulation in patients with a recent lapse. The differential patterns of autonomic alteration under methadone between those with and without lapse might offer an objective measure of lapse.

Autonomic modulation and health-related quality of life among schizophrenic patients treated with non-intensive case management.

BACKGROUND: Schizophrenia is associated with autonomic dysfunction and this may increase cardiovascular mortality. Past studies on autonomic modulation of schizophrenic patients focused on inpatients rather than individuals in a community setting, especially those receiving non-intensive case management (non-ICM). Besides, autonomic modulation and its association with health-related quality of life (HRQoL) in this population remain unexplored. METHODS: A total of 25 schizophrenic patients treated by non-ICM and 40 healthy volunteers were matched by age, gender and body mass index; smokers were excluded. Between the two groups, we compared the individuals' 5 min resting assessments of heart rate variability and their HRQoL, which was measured using EuroQoL-5D (EQ-5D). Patients with schizophrenia were assessed for psychopathology using the Positive and Negative Syndrome Scale for Schizophrenia (PANSS). We examined the relationship between heart rate variability measurements, HRQoL scores, PANSS scores, and other clinical variables among the schizophrenic patients treated by non-ICM. RESULTS: Compared to the controls, patients with schizophrenia showed a significant impairment of autonomic modulation and a worse HRQoL. Cardiovagal dysfunction among the schizophrenic patients could be predicted independently based on lower educational level and more negative symptoms. Sympathetic predominance was directly associated with anticholinergics use and EQ-5D using a visual analogue scale (EQ-VAS). CONCLUSION: Patients with schizophrenia treated by non-ICM show a significant impairment of their autonomic function and HRQoL compared to the controls. Since the sympathovagal dysfunction is associated with more negative symptoms or higher VAS score, the treatment of the negative symptoms as well as the monitoring of HRQoL might help to manage cardiovascular risk among these individuals. In addition, EQ-VAS scores must be interpreted more cautiously in such a population.
