Epidemiological knowledge of mucormycosis obtained from national population-based databases is scarce.This study aimed to depict the disease burden and demographics of mucormycosis in Taiwan by using the Taiwan National Health Insurance Research Database (NHIRD) and those of aspergillosis as a comparator.Data from patients with either mucormycosis or aspergillosis from 2006 to 2017 identified with the International Classification of Diseases (ICD) codes were extracted from the NHIRD. The incidence, demographics and clinical data of both diseases were analysed.A total of 204 patients with mucormycosis and 2270 patients with aspergillosis who were hospitalised and treated with mould-active antifungals between 2006 and 2017 were identified. The average annual incidence of aspergillosis (0.81 cases per 100,000 population [0.81/100,000]) was 11-fold higher than that of mucormycosis (0.07/100,000). A significant increase in incidence was observed for aspergillosis (from 0.48/100,000 in 2006 to 1.19/100,000 in 2017, p .0001) but not for mucormycosis (from 0.04/100,000 in 2006 to 0.11/100,000 in 2017, p = .07). The major underlying disease identified was diabetes mellitus (60.8%) for mucormycosis and malignant neoplasms (45.9%) for aspergillosis. The all-cause 90-day mortality rate was similar between mucormycosis and aspergillosis patients (39% vs. 37%, p = .60). For mucormycosis patients, multivariate analysis revealed that posaconazole use was associated with lower in-hospital mortality (aOR 0.38; 95% CI 0.15-0.97; p = .04).Mucormycosis is an uncommon fungal disease in Taiwan, occurring mostly in diabetic patients. However, the incidence might be underestimated due to limited diagnostics. Continuous surveillance might aid in delineating the evolving features of mucormycosis.

Natural disasters have negative health impacts on patients who need dialysis in affected areas. Severely affected areas are usually rural, with limited basic infrastructure and a population without optimal dialysis-specific care after a disaster. A population-based longitudinal case–cohort study enrolled 715,244 adults from the National Health Insurance Registry who lived in areas affected by a major natural disaster, Typhoon Morakot, in 2009. The observation period was from 2008 to 2011. A total of 13,268 patients (1.85%) had a history of end-stage renal disease (ESRD). Of the ESRD patients, 1264 patients (9.5%) received regular dialysis. Only eight patients missed dialysis sessions in the first month after the disaster. Compared to the moderately affected areas, the incidences of acute cerebrovascular and cardiovascular diseases were higher in patients in severely affected areas. Male dialysis patients aged 45–75 years had a higher mortality rate than that of the general population. Among the affected adults receiving regular dialysis, patients with diabetes (adjusted hazard ratio (aHR): 1.58, 95% confidence interval (CI): 1.20–2.08) or a history of cerebrovascular disease (aHR: 1.58, 95% CI: 1.12–2.21), chronic obstructive pulmonary disease (COPD) or asthma (aHR: 1.99, 95% CI: 1.24–3.17) in moderately affected areas had significantly elevated mortality rates. Additionally, among dialysis patients living in severely affected areas, those with a history of cerebrovascular disease (aHR: 4.52 95% CI: 2.28–8.79) had an elevated mortality rate. Early evacuation plans and high-quality, accessible care for cardiovascular and cerebrovascular diseases are essential to support affected populations before and after disasters to improve dialysis patients’ health outcomes.

Background: The neonatal changes of corpus callosum or cerebellar volume in preterm infants have been shown to link with abnormal mentality and motor disability in early childhood. This study aims to predict the long-term neurological outcomes by measuring these changes on neonatal brain ultrasound in preterm infants. Methods: Our cohort consisted of infants aged below 32 weeks' gestation with very low birth body weights who completed neuro-assessments at 5 years of age. Corpus callosum or cerebellar vermis were measured at 28–30 weeks and at 37–40 weeks gestational age in premature infants with cerebral palsy (CP), mental retardation (MR) and normal control premature infants. Results: There are 12 patients in MR group, 12 in CP group and 27 patients as controls for final analysis. There was no significant difference in other factors between study groups except lower gestational age (P = 0.043) in CP group. Respiratory distress syndrome was more common in MR group (P = 0.037) and cystic periventricular leukomalacia was more common in CP group (P

Dengue patients have an increased risk of acute gastrointestinal (GI) bleeding. However, whether dengue virus (DENV) infection can cause an increased long-term risk of GI bleeding remains unknown, especially among elderly individuals who commonly take antithrombotic drugs. A retrospective population-based cohort study was conducted by analyzing the National Health Insurance Research Databases. Laboratory-confirmed dengue patients from 2002 to 2012 and four matched nondengue controls were identified. Multivariate Cox proportional hazard regression was used to evaluate the acute (365 days) risks of nonvariceal upper GI bleeding after DENV infection. Stratified analyses by age group (≤50, 51–64, ≥65 years old) were also performed. In total, 13267 confirmed dengue patients and 53068 nondengue matched controls were included. After adjusting for sex, age, area of residence, comorbidities, and medications, dengue patients had a significantly increased risk of nonvariceal upper GI bleeding within 30 days of disease onset (adjusted HR 55.40; 95% CI: 32.17–95.42). However, DENV infection was not associated with increased medium-term and long-term risks of upper GI bleeding overall or in each age group. Even dengue patients who developed acute GI bleeding did not have increased medium-term (adjusted HR; 0.55, 95% CI 0.05–6.18) and long-term risks of upper GI bleeding (adjusted HR; 1.78, 95% CI 0.89–3.55). DENV infection was associated with a significantly increased risk of nonvariceal upper GI bleeding within 30 days but not thereafter. Recovered dengue patients with acute GI bleeding can resume antithrombotic treatments to minimize the risk of thrombosis., Author summary Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Dengue patients can have low platelet counts and might have acute gastrointestinal bleeding (tarry stool, bloody stool or bloody vomiting). Most dengue patients will fully recover and return to their previous health levels. Previous studies have indicated that some dengue patients have persistent low platelet counts and high inflammatory responses. The medium-term and long-term upper gastrointestinal bleeding risks remain unknown. Our study suggested that dengue was significantly associated with an increased risk of nonvariceal upper GI bleeding within 30 days after infection but was not associated with increased medium-term (31–365 days) and long-term risks (>365 days) of upper GI bleeding. Therefore, the risk of acute gastroenterology bleeding returned to baseline levels after 30 days. Recovered dengue patients with acute GI bleeding can resume antiplatelet, antithrombotic, and oral anticoagulation (OAC) treatments.

The coronavirus disease 2019 (COVID-19) pandemic caused by a novel coronavirus, SARS-CoV-2, has infected more than 22 million individuals and resulted in over 780,000 deaths globally. The rapid spread of the virus and the precipitously increasing numbers of cases necessitate the urgent development of accurate diagnostic methods, effective treatments, and vaccines. Here, we review the progress of developing diagnostic methods, therapies, and vaccines for SARS-CoV-2 with a focus on current clinical trials and their challenges. For diagnosis, nucleic acid amplification tests remain the mainstay diagnostics for laboratory confirmation of SARS-CoV-2 infection, while serological antibody tests are used to aid contact tracing, epidemiological, and vaccine evaluation studies. Viral isolation is not recommended for routine diagnostic procedures due to safety concerns. Currently, no single effective drug or specific vaccine is available against SARS-CoV-2. Some candidate drugs targeting different levels and stages of human responses against COVID-19 such as cell membrane fusion, RNA-dependent RNA polymerase, viral protease inhibitor, interleukin 6 blocker, and convalescent plasma may improve the clinical outcomes of critical COVID-19 patients. Other supportive care measures for critical patients are still necessary. Advances in genetic sequencing and other technological developments have sped up the establishment of a variety of vaccine platforms. Accordingly, numerous vaccines are under development. Vaccine candidates against SARS-CoV-2 are mainly based upon the viral spike protein due to its vital role in viral infectivity, and most of these candidates have recently moved into clinical trials. Before the efficacy of such vaccines in humans is demonstrated, strong international coordination and collaboration among studies, pharmaceutical companies, regulators, and governments are needed to limit further damage due the emerging SARS-CoV-2 virus.

Neonatal hypoxic–ischemic encephalopathy is the most common cause of neurological disability in infancy. Superimposed inflammation may further worsen neurological outcomes. Reliable biomarkers which are both sensitive to hypoxic-ischemia and inflammation are critically needed. We tested plasma osteopontin (OPN) and glial fibrillary astrocytic protein (GFAP) within the reported therapeutic window (90 min after hypoxic-ischemic (HI) injury) in neonatal rats with different HI severity and inflammation. Two different HI severity groups (mild-HI with 75 min hypoxia and severe-HI with 150 min hypoxia) were established. Inflammation-sensitized HI brain injury induced by lipopolysaccharide (LPS) further increased apoptotic neurons and infarct volumes. In HI alone groups, OPN was significantly decreased (p

Aim Radiation‐related injury in the general population due to accidents or incidents is a rare but significant event that merits serious study and planning in the health‐care system. Therefore, we developed different levels of training courses targeting medical emergency response and treatment for radiation‐related injury in patients, for different health‐care professionals and medical students. Methods The curriculum, teaching instructions, and objectives were based on the working group consensus of first responders of radiation‐related injury. The working group included different specialists from hospitals, medical schools, and government radiation emergency response agencies. Results Several different course levels, including lectures, group discussions, case and scenario discussions, hands‐on practice, tabletop drills, and drills were included. The curriculums have shown that developing different levels of courses for medical students and health‐care professionals was feasible. Conclusion Through the cooperation of different specialties and different interactive courses, the training programs were able to meet the initial education goals for medical emergency and radiation‐related injury for medical students and health‐care professionals., Different levels of education and training programs for radiation related injury patients with the cooperation from local healthcare facilities, fire department, regional response center, national authorities is feasible. Medical students, healthcare professionals, medical physicists and first responders were able to acquire the knowledge and have practice experiences on the management of radiation related injury.

Background/Purpose Typhoon Morakot in August 2009 caused significant damages and health and socio-economic impacts in Taiwan. Therefore, we evaluated the mental health status of adult and patients who lived in the affected area after the disaster. Methods An observational, prospective population-based study was conducted. Adults living in the affected area were selected as the affected population in the National Health Insurance Database from January 2008 to December 2011. Prevalence and incidence of stress-associated illnesses, such as insomnia, anxiety, depressive, adjustment and mood disorders, post-traumatic stress disorder (PTSD) in the psychiatry department were analysed after the disaster. Results A total of 897,689 adult patients were studied. Of the affected population without pre-existing chronic mental health illness, the monthly visits for stress-associated illnesses, such as insomnia, anxiety, depressive disorders and PTSD increased about twice after the disaster in elderly and non-elderly groups. Comparing to the non-elderly group, the elderly group has more increased in the incidence of insomnia (356% vs. 318% increase) and depressive disorders (308% vs. 245%) but was affected to a lesser extent increase in the anxiety (269% vs. 307%), PTSD, episodic mood disorders (82% vs. 158%), and adjustment reaction (160% vs. 202%). Conclusion The mental health statuses of patients who experienced a major natural disaster deteriorated in the elderly population after the disaster. However, we still need pay more attentions on the elderly of the affected population to decrease the risk for insomnia and depressive disorders after the disaster.

A serosurvey of 600 workers newly arrived in Taiwan from 4 Southeast Asia countries showed that 18 (3%) were positive for Zika virus IgM; 6 (1%) fulfilled the World Health Organization criteria for laboratory-confirmed recent Zika virus infection. The incidence of Zika virus infection in Southeast Asia might be underestimated.

Background: Neonatal hypoxic-ischemic encephalopathy (HIE) is the most common cause of mortality and neurological disability in infancy after perinatal asphyxia. Reliable biomarkers to predict neurological outcomes of neonates after perinatal asphyxia are still not accessible in clinical practice. Methods: A prospective cohort study enrolled neonates with perinatal asphyxia. Biochemical blood tests and cerebral Doppler ultrasound were measured within 6 h of age and at the 4th day old. Neurological outcomes were assessed at 1 year old. Results: Sixty-four neonates with perinatal asphyxia were enrolled. Fifty-eight (90%) had hypoxic-ischemic encephalopathy (HIE) including 20 (34%) Stage I, 21 (36%) Stage II, and 17 (29%) Stage III. In the asphyxiated infants without therapeutic hypothermia, HIE stage, PH, and base excess levels within 6 h of age were the predictors of adverse outcomes. In the asphyxiated infants receiving therapeutic hypothermia, HIE stage failed to predict outcomes. Instead, blood lactate levels and pulsatility index (PI) of medial cerebral arteries (MCA) either in 6 h of age or at the 4th day old independently predicted adverse outcomes. Conclusions: Blood lactate, which is a common accessible test at the hospital and MCA PI on cerebral ultrasound could predict adverse outcomes in asphyxiated infants receiving therapeutic hypothermia.

Background : Methicillin-resistant Staphylococcus aureus (MRSA) is a major public health concern worldwide. Healthcare workers (HCWs) are an important source of transmission of MRSA. We conducted a prospective study to define the frequency of S. aureus nasal colonization and emphasize on the carriage of MRSA in HCWs in relation to the intensity of patient contact. Methods: To evaluate the prevalence of S. aureus carriage and the relevance of transmission from community to the hospital, MRSA and methicillin-susceptible S. aureus (MSSA) nasal colonization in selected HCWs was compared. These included an emergency department, intensive care unit, out-of-hospital care emergency medical technicians and students, and a long-term care facility (LTCF). The MRSA isolates were further identified by their microbiological and molecular characteristics. Results: S. aureus was isolated from 63 of 248 HCWs (25.4%). The overall MRSA nasal carriage rate was 15/248, 6%. Most MRSA carriers were female (14/15, 93.3%), and HCWs who had worked for ≥5 years (11/15, 73.3%). LTCFs had the highest prevalence (3/25, 12%). In contrast, the overall carriage of MSSA was 48/248, 19.4%, and most carriers worked for ≥5 years (25/48, 52.1%). Hospital nurses had the highest rate of MSSA carriage (22/103, 21.4%). Most of the MRSA isolates were SCC mec IV/ST59 or ST45 (60%), and were resistant to erythromycin and clindamycin (53%). Only one MRSA was chlorhexidine resistant. All produced low level of biofilms. Conclusions: This study demonstrates hospital nurses have highest S. aureus nasal carriage, whereas HCWs worked in the LTCFs have the highest prevalence of nasal MRSA colonization. The differences in the characteristics of MRSA and MSSA nasal carriage among HCWs highlights the importance on inclusion of all strains of S. aureus in surveillance and infection control programs.

The 2015 dengue outbreak in southern Taiwan turned into a public health emergency, resulting in a large-scale mobilization of personnel from the emergency department (ED) services operating in and near full capacity to assist with the outbreak. This study aimed to assess a rapid independent clinic-based service (RCS), which was set up and designed to relieve the overcrowding of the regular ambulatory and emergency services during an epidemic of dengue. This is a retrospective cross-sectional study. National Cheng Kung University Hospital, Tainan, Taiwan. Patients with positive test results were enrolled and reviewed to evaluate the efficacy of RCS implementation between August and October 2015. The case-treatment rates stratified by length of stay (LOS) were used to examine the performance of the RCS that was set up outside the ED and designed to relieve the overcrowding of the regular ambulatory and emergency services. Patients with dengue-like illnesses may arrive at the hospital and require optimal ED triage and management thereafter. Although the outbreak resulted in a shortage of spare space in the ED, a proper response from the hospital administration would ameliorate the work overload of the staff and would not decrease the quality of care for critical patients. An early and restrictive intensive intervention was beneficial to health care facilities during a dengue outbreak. Further planning and training of the RCS could be crucial for hospital preparedness for infectious disease outbreaks.

Natural disasters have negative health impacts on chronic diseases in affected populations. Severely affected areas are usually rural areas with limited basic infrastructure and a population have that has limited access to optimal healthcare after a disaster. Patients with cardiovascular diseases are required to maintain quality care, especially after disasters. A population-based case-control study enrolled adults from the National Health Insurance Registry who had ischemic heart disease and cerebrovascular disease histories and lived in the area affected by Typhoon Morakot in 2009. Monthly medical visits for acute cerebrovascular and ischemic heart diseases markedly increased at approximately 1&ndash, 2 months after the typhoon. Survival analysis during the two years following the typhoon indicated a significant increase in mortality in adults with an acute ischemic heart disease history who lived in the severely affected area. Mortality hazard analysis showed that among affected adults with previous cerebrovascular diseases and acute ischemic heart diseases, patients with diabetes (adjusted hazard ratio [HR]: 1.3&ndash, 1.7), Chronic Kidney Disease (CKD) (adjusted HR: 2.0&ndash, 2.7), chronic obstructive pulmonary diseases (COPD) and asthma (adjusted HR: 1.7&ndash, 2.1), liver cirrhosis (adjusted HR: 2.3&ndash, 3.3) and neoplasms (adjusted HR: 1.1&ndash, 2.1) had significantly increased mortality rates. Consequently, high-quality and accessible primary healthcare plans should be made available to maintain and support affected populations after disasters.

Objectives. We develop an epidemiological approach to determine the emergency patients at high risk of severe dengue (SD), known as hemorrhagic fever (DHF) or dengue shock syndrome (DSS), and to fa...

Objective Acute transverse myelitis (ATM) is a focal inflammatory disorder of the spinal cord, resulting in motor, sensory, and autonomic dysfunction. In this study, we delineate the clinical manifestations, neuroimaging characteristics, and outcome-associated risk factors in children with idiopathic ATM. Methods We retrospectively reviewed the medical charts and neuroimages in nine children aged younger than 18 years diagnosed with ATM between January 2006 and August 2014. Results The mean onset age was 5 years and 9 months. Infectious prodromes were observed in six patients. Leg weakness was observed in all patients, autonomic sphincter dysfunction was observed in seven patients, and sensory deficits on admission were observed only in four patients. The diagnosis was delayed in patients younger than 5.5 years compared with older children. The adverse outcomes cannot be predicted by the course of the disease, the laboratory findings, nor the extent of magnetic resonance imaging–detected spinal lesions; however, these outcomes can be predicted by poor early response to corticosteroids and the requirement of additional treatments ( p Conclusion The diagnosis of ATM is challenging in young children. Children with ATM who responded early to corticosteroids had more favorable outcomes than those who required additional therapies.

Background:Previous studies have found that social cohesion and trust (SCT) were associated with psychological well-being and physical health. In this study, we investigated the associations between SCT and mental and physical health among community-dwelling elderly in a town in southern Taiwan.Methods:The study population consisted of 149 community-dwelling elderly aged 65 years and older (68 men, 81 women; mean age, 75.4 ± 6.1 years) residing in the town of Dashe in southern Taiwan. Activities of daily living (ADL), SCT, depression, subjective quality of life (QOL), current medical status, past medical history, and health behaviors were assessed in face-to-face interviews. Objective neurobehavioral functions were assessed using the timed up & go (TUG) test, functional reach test, and handgrip test.Results:Scores for ADL and Geriatric Depression Scale (GDS) were significantly correlated with SCT, and SCT was significantly correlated with all subjective QOL items. In addition, a strong correlation was observed between SCT and relationship with friends. Values for SCT (median ≥ 20) were significantly associated with both subjective sense of health (median ≥ 68) and subjective happiness (median ≥ 73) after adjusting for age, sex, and ADL.Conclusion:SCT is an important variable that influences self-rated health and happiness, independently of ADL, age, and sex. When assessing geriatric psychological function, SCT should be examined more carefully, given its association with subjective sense of health and happiness, depression, and physical function.

Summary Emerging azole resistance in Aspergillus fumigatus poses a serious threat to human health. This nationwide surveillance study investigated the prevalence and molecular characteristics of azole-resistant A. fumigatus environmental isolates in Taiwan, an island country with increasing use of azole fungicides. Of the 2,760 air and soil samples screened from 2014-2016, 451 A. fumigatus isolates were recovered from 266 samples, and 34 isolates from 29 samples displayed resistance to medical azoles (itraconazole, voriconazole, or posaconazole). The resistance prevalence was 10.9% and 7.5% in A. fumigatus-positive samples and isolates, respectively. Most (29, 85.3%) azole-resistant isolates harbored TR34/L98H mutations, which were widely distributed, clustered genetically with clinical isolates, and had growth rates that were similar to those of the wild-type isolates. Microsatellite genotyping revealed both the global spread of the TR34/L98H isolates and the occurrence of TR34/L98H/S297T/F495I isolates belonging to local microsatellite genotypes. AfuMDR3 and atrF, two efflux transporter genes, were constitutively upregulated in two individual resistant isolates without cyp51A mutations, highlighting their potential roles in azole resistance. These results emphasize the need for periodic environmental surveillance at the molecular level in regions in which azole fungicides are applied, and agricultural fungicide management strategies that generate less selective pressure should be investigated.

The aim of the investigation was to describe the incidence of Aeromonas bacteremia in a city with a population of about 1.87 million inhabitants, located in southern Taiwan, between 2008 and 2010. Such data were compared with the incidences of Vibrio and Salmonella bacteremia in the same period and the incidence of Aeromonas bacteremia in other countries in the literature. The data revealed the average annual incidences of bacteremia due to Aeromonas, Vibrio, and Salmonella species were 76, 38, and 103 cases/million inhabitants, respectively. The incidence of Aeromonas bacteremia was higher than those in Western countries.

Outcome prediction for out-of-hospital cardiac arrest (OHCA) is of medical, ethical, and socioeconomic importance. We hypothesized that blood ammonia may reflect tissue hypoxia in OHCA patients and conducted this study to evaluate the prognostic value of ammonia for the return of spontaneous circulation (ROSC).This prospective, observational study was conducted in a tertiary university hospital between January 2008 and December 2008. The subjects consisted of OHCA patients who were sent to the emergency department (ED). The primary outcome was ROSC. The prognostic values were calculated for ammonia levels and the partial pressure of ammonia (pNH(3)), and the results were depicted as a receiver operating characteristics curve with an area under the curve.Among 119 patients enrolled in this study, 28 patients (23.5%) achieved ROSC. Ammonia levels and pNH(3) in the non-ROSC group were significantly higher than those in the ROSC group (167.0 μmol/L vs 80.0 μmol/L, P.05; 2.61 × 10(-5) vs 1.67 × 10(-5) mm Hg, P.05, respectively). The predictive capacity of area under the curve for ammonia and pNH(3) for non-ROSC was 0.85 (95% confidence interval, 0.75-0.95) and 0.73 (95% confidence interval, 0.61-0.84), respectively. The multivariate analysis confirmed that ammonia and pNH(3) are independent predictors of non-ROSC. The prognostic value of ammonia was better than that of pNH(3). The cutoff level for ammonia of 84 μmol/L was 94.5% sensitive and 75.0% specific for predicting non-ROSC with a diagnostic accuracy of 89.9%.Hyperammonemia on ED arrival is independently predictive of non-ROSC for OHCA patients. The findings may offer useful information for clinical management.

Objective Although geriatric syndromes have been studied extensively, their interactions with one another and their accumulated effects on life expectancy are less frequently discussed. This study examined whether geriatric syndromes and their cumulative effects are associated with risks of mortality in community-dwelling older adults. Methods Data were collected from the Taiwan Longitudinal Study in Aging in 2003, and the participant survival status was followed until December 31, 2007. A total of 2744 participants aged ≥65 years were included in this retrospective cohort study; 634 died during follow-up. Demographic factors, comorbidities, health behaviors, and geriatric syndromes, including underweight, falls, functional impairment, depressive condition, and cognitive impairment, were assessed. Cox proportional hazard regression analysis was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) for the probability of survival according to the cumulative number of geriatric syndromes. Results The prevalence of geriatric syndromes increased with age. Mortality was significantly associated with age ≥75 years; male sex; ≤6 years of education; history of stroke, malignancy; smoking; not drinking alcohol; and not exercising regularly. Geriatric syndromes, such as underweight, functional disability, and depressive condition, contributed to the risk of mortality. The accumulative model of geriatric syndromes also predicted higher risks of mortality (N = 1, HR 1.50, 95% CI 1.19–1.89; N = 2, HR 1.69, 95% CI 1.25–2.29; N ≥ 3, HR 2.43, 95% CI 1.62–3.66). Conclusions Community-dwelling older adults who were male, illiterate, receiving institutional care, underweight, experiencing a depressive condition, functionally impaired, and engaging in poor health behavior were more likely to have a higher risk of mortality. The identification of geriatric syndromes might help to improve comprehensive care for community-dwelling older adults.

To determine the impact of delayed admission to the intensive care unit (ICU) on the clinical outcomes of patients with acute respiratory failure (ARF) in the emergency department (ED).This retrospective cohort study included non-traumatic adult patients with ARF and mechanical ventilation support in the ED of a tertiary university hospital in Taiwan from January 1, 2013, to August 31, 2013. Clinical data were extracted from chart records. The primary and secondary outcome measures were a prolonged hospital stay (30 days) and the in-hospital crude mortality within 90 days, respectively.For 267 eligible patients (age range 21.0-98.0 years, mean 70.5±15.1 years; male 184, 68.9%), multivariate analysis was used to determine the significant adverse effects of an ED stay1.0 hour on in-hospital crude mortality (odds ratio 2.19, P.05), which was thus defined as delayed ICU admission. In-hospital mortality significantly differed between patients with delayed ICU admission and those without delayed admission, as revealed by the Kaplan-Meier survival curves (P.05). Moreover, a linear-by-linear correlation was observed between the length of ICU waiting time in the ED and the lengths of total hospital stay (r=0.152, P.05), ICU stay (r=0.148, P.05), and ventilator support (r=0.222, P.05).For patients with ARF who required mechanical ventilation support and intensive care, a delayed ICU admission more than 1.0 hour is a strong determinant of mortality and is associated with a longer ICU stay and a longer need for ventilation.

Dengue infection is a major health problem in tropical and subtropical countries. A prospective observational study in a university-affiliated hospital was conducted between August 2015 and September 2015. Patients who visited the emergency department (ED) with a presentation of any symptoms of dengue were eligible for the dengue non-structural protein 1 (NS1), IgM/IgG rapid immunochromatographic tests and real-time polymerase chain reaction (RT-PCR) to evaluate the performance of the rapid tests. Considering the RT-PCR as the gold standard for the dengue diagnosis, the ideal primary results of sensitivity (80–100%), specificity (60–84%), positive predicted value(75%-95%), and negative predicted value (70–100%) suggested that the NS1-based test with or without a combination of IgM and IgG tests have good diagnostic performances in detecting dengue infections, even in the afebrile or elderly populations.

Background. Nontyphoid Salmonella (NTS) can cause fatal vascular infections. This study aims to establish a predictive scoring algorithm to identify adults aged ≥50 years with NTS bacteremia who are at risk for vascular infections. Methods. There were 358 adults aged ≥50 years with NTS bacteremia at 2 medical centers in southern Taiwan included in this study. Multiple logistic regression was used to identify risk factors for imaging-documented vascular infections. The prediction capability of the proposed scoring algorithm was indicated by a receiver operating characteristic curve and measures of sensitivity and specificity. Results. Sixty patients (16.8%) with vascular infections were noted. The 4 risk factors significantly associated with vascular infections—male sex, hypertension, coronary arterial disease, and serogroup C1 infections—were each assigned +1 point to form the NTS vascular infection (NTSVI) score. In contrast, malignancy and immunosuppressive therapy were each assigned −1 point, owing to their negative associations with vascular infections. Based on the proposed NTSVI scoring, the prevalence of vascular infections in patients with ≤0, 1, 2, 3, or 4 points was 2.2% (3 of 138 patients), 10.6% (13 of 123 patients), 39.4% (26 of 66 patients), 55.2% (16 of 29 patients), and 100% (2 of 2 patients), respectively (P< .0001). The scoring algorithm shows an area under the curve of 0.83 (95% confidence interval, .78–.89; P< .0001). A cutoff value of +1 represents a high sensitivity (95.0%) and an acceptable specificity (45.3%). Conclusions. This simple scoring algorithm can be used to identify patients with NTS bacteremia with a high risk of vascular infections. The cost-effectiveness of this algorithm should be further studied.

In Taiwan, the tuberculin skin test (TST) is not recommended as a screening test for Mycobacterium tuberculosis (TB) infections. The aim of this study is to determine the prevalence and predictors of positive tuberculin reactivity and its association with TB infections among nursing home residents in Taiwan. A cross-sectional study and review of medical records were conducted at four nursing homes in Tainan City. A one-stage TST was performed by study nurses using two tuberculin units of purified protein derivative (PPD) of the RT23 strain. An induration ≥10 mm at 72 h was considered to be a positive reaction. Chest radiographs, acid-fast stains and mycobacterial cultures of three sputum samples were performed for those with a positive TST result. Of 115 residents (66.5% participation, mean age 73.1 years) who underwent a TST, 26 (22.6%) had a positive reaction. One woman was microbiologically diagnosed to have pulmonary TB. On multivariate analysis, a Bacille Calmette-Guerin (BCG) scar and a history of myocardial infarction were significantly associated with a positive TST. In conclusions, this study shows a considerable rate of positive TST among nursing home residents in southern Taiwan. A BCG scar and a history of myocardial infarction were associated with a positive TST.

Background/Purpose: Aeromonas infections, rarely reported in Western countries, are not uncommon infectious diseases in Taiwan. The clinical manifestations and prognostic factors of Aeromonas spontaneous bacterial peritonitis (SBP) in patients with liver cirrhosis were investigated. Methods: We reviewed the medical charts and microbiological records of liver cirrhosis patients with Aeromonas SBP between January 1990 and December 2005, in a medical center in southern Taiwan. Results: Thirty-one liver cirrhosis patients developed Aeromonas SBP within a 16-year period. The majority (26, 84%) had concurrent Aeromonas bacteremia. A. sobria (55%) and A. hydrophila (45%) were the causative species. The predominant clinical manifestations included fever (84%), abdominal pain (74%), hypotension on admission (48%), altered mental status (45%), and acute renal failure (42%). Gram-negative bacilli were found in Gram staining of ascitic fluids in 27% of 26 patients, while aeromonads were isolated from ascitic fluids in 55% of 31 patients. The yield rate of ascitic fluid cultures decreased greatly, if paracentesis was performed at＞3 hours after the administration of antimicrobial therapy. All but one patient received in-vitro-active antimicrobial agents within 48 hours, but the all-cause mortality rate was 56%. Initial high Pitt's bacteremia score was independently associated with a fatal outcome in multivariate analysis. Conclusion: Aeromonas SBP is a fatal disease, and must be included in the differential diagnosis of SBP in patients with advanced liver cirrhosis in endemic areas.
