RESUMEN
BACKGROUND: An unscheduled return visit (URV) to the emergency department (ED) within 72-h is an indicator of ED performance. An unscheduled return revisit (URV) within 72-h was used to monitor adverse events and medical errors in a hospital quality improvement program. The study explores the potential factors that contribute to URV to the ED within 72-h and the unscheduled return revisit admission (URVA) in adults below 50 years old. METHODS: The case-control study enrolled 9483 URV patients during 2015-2020 in National Cheng-Kung University Hospital. URVA and URV non-admission (URVNA) patients were analyzed. The Gini impurity index was calculated by decision tree (DT) to split the variables capable of partitioning the groups into URVA and URVNA. Logistic regression is applied to calculate the odds ratio (OR) of candidate variables. The α level was set at 0.05. RESULTS: Among patients under the age of 50, the percentage of females in URVNA was 55.05%, while in URVA it was 53.25%. Furthermore, the average age of URVA patients was 38.20 ± 8.10, which is higher than the average age of 35.19 ± 8.65 observed in URVNA. The Charlson Comorbidity Index (CCI) of the URVA patients (1.59 ± 1.00) was significantly higher than that of the URVNA patients (1.22 ± 0.64). The diastolic blood pressure (DBP) of the URVA patients was 85.29 ± 16.22, which was lower than that of the URVNA (82.89 ± 17.29). Severe triage of URVA patients is 21.1%, which is higher than the 9.7% of URVNA patients. The decision tree suggests that the factors associated with URVA are "severe triage," "CCI higher than 2," "DBP less than 86.5 mmHg," and "age older than 34 years". These risk factors were verified by logistic regression and the OR of CCI was 2.42 (1.50-3.90), the OR of age was 1.84 (1.50-2.27), the OR of DBP less than 86.5 was 0.71 (0.58-0.86), and the OR of severe triage was 2.35 (1.83-3.03). CONCLUSIONS: The results provide physicians with a reference for discharging patients and could help ED physicians reduce the cognitive burden associated with the diagnostic errors and stress.

Advanced digital technologies have overcome the limitation of on-site teaching, especially after the COVID-19 epidemic. Various newly-developed digital technologies, such as e-learning, virtual reality, serious games, and podcasts, have gained renewed interest and come into the spotlight. Podcasts are becoming increasingly popular in nursing education as they provide a convenient and cost-effective way for students to access educational content. This mini-review article provides an overview of the development of podcasts in nursing education in Eastern and Western countries. It explores potential future trends in the use of this technology. The literature review demonstrates that nursing education in Western countries has already integrated podcasts into curriculum design, using the podcast to convey nursing education knowledge and skills and to improve students' learning outcomes. However, few articles address nursing education in Eastern countries. The benefits of integrating podcasts into nursing education appear far greater than the limitations. In the future, the application of podcasts can serve not only as a supplement to instructional methodologies but also as a tool for clinical practicing students in nursing education. In addition, with the aging population increasing in both Eastern and Western countries, podcasts have the potential to serve as an effective delivery modality for health education in the future, particularly for the older adult, whose eyesight declines with age, and those populations with visual impairments.

Background: Remote teaching and online learning have significantly changed the responsiveness and accessibility after the COVID-19 pandemic. Disaster medicine (DM) has recently gained prominence as a critical issue due to the high frequency of worldwide disasters, especially in 2021. The new artificial intelligence (AI)-enhanced technologies and concepts have recently progressed in DM education. Objectives: The aim of this article is to familiarize the reader with the remote technologies that have been developed and used in DM education over the past 20 years. Literature scoping reviews: Mobile edge computing (MEC), unmanned aerial vehicles (UAVs)/drones, deep learning (DL), and visual reality stimulation, e.g., head-mounted display (HMD), are selected as promising and inspiring designs in DM education. Methods: We performed a comprehensive review of the literature on the remote technologies applied in DM pedagogy for medical, nursing, and social work, as well as other health discipline students, e.g., paramedics. Databases including PubMed (MEDLINE), ISI Web of Science (WOS), EBSCO (EBSCO Essentials), Embase (EMB), and Scopus were used. The sourced results were recorded in a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flowchart and followed in accordance with the PRISMA extension Scoping Review checklist. We included peer-reviewed articles, Epubs (electronic publications such as databases), and proceedings written in English. VOSviewer for related keywords extracted from review articles presented as a tabular summary to demonstrate their occurrence and connections among these DM education articles from 2000 to 2022. Results: A total of 1,080 research articles on remote technologies in DM were initially reviewed. After exclusion, 64 articles were included in our review. Emergency remote teaching/learning education, remote learning, online learning/teaching, and blended learning are the most frequently used keywords. As new remote technologies used in emergencies become more advanced, DM pedagogy is facing more complex problems. Discussions: Artificial intelligence-enhanced remote technologies promote learning incentives for medical undergraduate students or graduate professionals, but the efficacy of learning quality remains uncertain. More blended AI-modulating pedagogies in DM education could be increasingly important in the future. More sophisticated evaluation and assessment are needed to implement carefully considered designs for effective DM education.

BACKGROUND: Glucocorticoids (GCs) have been extensively used as essential modulators in clinical infectious and inflammatory diseases. The GC receptor (GR) is a transcription factor belonging to the nuclear receptor family that regulates anti-inflammatory processes and releases pro-inflammatory cytokines, such as interleukin (IL)-6. RESULTS: Five putative GR binding sites and other transcriptional factor binding sites were identified on theIL-6 promoter, and dexamethasone (DEX) was noted to reduce the lipopolysaccharide (LPS)-induced IL-6 production. Among mutant transcriptional factor binding sites, nuclear factor-kappa B (NF-κB), activator protein (AP)-1, and specificity protein (Sp)1-2 sites reduced basal and LPS-induced IL-6 promoter activities through various responses. The second GR binding site (GR2) was noted to play a crucial role in both basal and inducible promoter activities in LPS-induced inflammation. CONCLUSIONS: We concluded that selective GR2 modulator might exert agonistic and antagonistic effects and could activate crucial signaling pathways during the LPS-stimulated inflammatory process.

BACKGROUND: An effective treatment strategy for peritoneal metastasis (PM) of hepatocellular carcinoma (HCC-PM) has yet to be established. Although cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have shown favorable outcomes in certain malignancies, their role in peritoneal metastatic HCC is unclear. Herein, we present a series of patients with HCC-PM treated with CRS/HIPEC and evaluate their outcomes. METHODS: Records of patients with HCC-PM who had undergone CRS/HIPEC at the Hyperthermia Center of Yuan's General Hospital, Kaohsiung, Taiwan, between September 2015 and December 2016 were reviewed retrospectively. Patients were followed up until September 2019. We assessed the clinical courses and outcomes of these patients to clarify the benefits of CRS/HIPEC. RESULTS: Six patients were included in our study. HCC-PM occurred synchronously in one patient and occurred metachronously in five patients after therapeutic minimally invasive procedures, including radiofrequency ablation, laparoscopic hepatectomy, robotic hepatectomy or spontaneously. The median peritoneal cancer index was 18.5. All patients experienced complete peritoneal cytoreduction without perioperative mortality. One patient had two CTCAE grade 3 complications. The median follow-up was 16âmonths. The median overall survival was 15.7âmonths. Four patients died of lung metastasis or liver failure owing to intrahepatic recurrence. The survival rates observed at 1, 2, and 4âyears were 66.7%, 33.3%, and 33.3%, respectively. CONCLUSIONS: CRS followed by HIPEC is feasible in patients with HCC-PM and might provide selected patients a chance for local disease control and longer survival. CRS/HIPEC might be considered as a treatment option in highly selected patients, as part of multimodal therapy approaches.
RESUMEN
BACKGROUND: Taiwan is geographically located in a zone that is vulnerable to earthquakes, typhoons, floods, and landslide hazards and has experienced various disasters. Six Regional Emergency Medical Operation Centers (REMOCs) are integrated and administered by the Ministry of Health and Welfare (MOHW) to be responsible for emergency situations during disastrous events, such as the emission of chemical toxicants, traffic accidents, industrial materials containment, and typhoons. OBJECTIVE: To analyze events reported by the six REMOCs during the 2014 to 2018 for the government policy reference. METHODS: Data were collected from injured and death toll reports provided by local designated hospitals in the emergency medical reporting system. Disaster events were categorized into three categories: natural disaster (NDs), disasters associated with technology (DTs), and disasters associated with security/violence/others (DSVOs). The three categories were further subdivided into sub-categories. Variables considered for trend analyses included the number of wounded and deaths, event characteristics, date/time, and triage. The frequency of disaster events among the six REMOCs was compared using the chi-square test. We used the global information system (GIS) to describe the distribution of events in Taiwan metropolitan cities. The α-level was set at 0.05. RESULTS: Of 580 events during the study period, the distribution of disaster characteristics in the jurisdictions of the six REMOCs were different. The majority of disaster events were DTs (64.5%), followed by NDs (24.5%) and DSVOs (11.0%). Events for the three disaster categories in the six REMOCs were different (χ2-test, p < 0.001). Furthermore, for the Taipei branch (Northern Taiwan), other NDs, especially heatwaves and cold spells, were most reported in New Taipei City (92.2%) and showed an increasing annual trend; for the Kaohsiung branch (Southern Taiwan), DT events were the most reported, especially in Kaohsiung City; and for the Taichung branch (Central Taiwan), DSVOs were the most reported, especially in Taichung City. CONCLUSION: Our data revealed that extreme weather precautions reported in the Taipei branch were increasing. Disaster characteristics were different in each metropolitan city. Upgrading the ability to respond to natural disasters is ineluctable.

BACKGROUND: Severe dengue virus (DENV) infection involves plasma leakage and vascular collapse, and leads to significant morbidity and death. Serum soluble ST2 (sST2 [interleukin (IL)-1 receptor like-1 protein: IL-1-RL-1]) levels are high in pediatric cases of DENV infection, and the disease progresses. However, the correlation between serum sST2 levels and the outcomes of DENV infection in the elderly (≥65 years) is unclear. We thus explored the mechanisms of serial sST2 level changes involved in the coagulopathy and bloodstream infections of elderly patients in Taiwan's 2015 DENV outbreak. METHODS: This retrospective study was done in a tertiary medical center in southern Taiwan during the outbreak. All DENV-infected patients who, between July 1, 2015, and December 31, 2015, provided a written informed consent for at least two blood sample analyses were enrolled and reviewed. The serum levels of sST2 were quantified. ΔsST2 is defined as the "changes of sST2 levels in serially paired samples". Receiver operating characteristic (ROC) curve and area under the ROC curve (AUC) analyses were used to evaluate the prognostic ability of ΔsST2. RESULTS: Forty-three patients with DENV infection were enrolled. Mean patient age was 75.0 ± 12.2 years and the case fatality rate was 44.2% (19/43). Significantly more non-survivors than survivors had increased ST2 level (78.9% vs. 12.5%, p < 0.001). The AUC value for serum ΔsST2 level was 0.857 for predicting DENV fatality. Moreover, patients given frozen fresh plasma (FFP) transfusions were significantly (p = 0.025) more likely to have higher serum ST2 level changes than were those who had not. DENV-infected patients with early bloodstream infections (BSIs) seemed to have higher ST2 levels than those who did not have BSIs. CONCLUSIONS: Serum ST2 levels increased in the elderly (≥ 65 years of age) with DENV infection. The changes in serum sST2 levels might be a critical indicator of DENV infection severity for the elderly; sST2 is an important modulator of coagulopathy in severe DENV infections.

OBJECTIVE: In Taiwan, light motorcycles (LMCs) with cylinder capacities between 50 and 250 cc are widely used for daily commute. These vehicles are operated in a mixed traffic environment and prohibited on highways. In light of increasing motorcycle casualties, we conducted a multicentre study to analyse rider factors affecting injury severity. METHODS: Riders hospitalised upon LMC crashes were contacted. Information on demographics, comorbidities, and riding behaviours was collected through questionnaires and linked to hospital data. The injury severity score (ISS) and length of hospitalisation (LOH) were used as injury severity measures. RESULTS: In total, 725 patients (mean age: 37.7 years; 64% men) completed their questionnaires. Multivariate analysis results showed that age ≥ 65 years, half-face helmets, protective clothing, collisions with a bus/truck or car, and fatigue riding were risk factors for having an ISS of ≥9. Age ≥ 65 years; motorcycle crashes ≥2 times in the previous year; anaemia; rural crashes; half-face helmets; protective boots; collisions with a bus/truck, car, or a stationary object; alcohol/stimulating refreshment consumption; and fatigue riding were risk factors for increased LOH. A protective factor was individuals working in commerce. Collisions with opening car doors caused low risks of having an ISS of ≥9 and a short LOH. CONCLUSION: Certain factors were significantly associated with riders' injury severity and related medical resource consumption. Because of differences in the power output, use, and riding environment, risk factors for severe injuries in LMC crashes are dissimilar from those for heavy motorcycles (cylinder capacities > 250 cc) in developed countries and deserve more attention for injury prevention. Further in-depth evaluation of significant factors based on this study's results can yield valuable information to reduce severe injuries after LMC crashes in countries and areas with a high dependency on motorcycles, even considering the popularity of electric motorcycles.

INTRODUCTION: Right-sided native endocarditis is a difficult case with fewer cardiac symptoms and fewer classic signs of cutaneous vascular lesions compared with left-sided endocarditis. PATIENT CONCERNS: A 68-year-old Taiwanese man with a history of gouty arthritis, hyperlipidemia, and adrenal insufficiency presented to our ED and complained dyspnea and low back pain for 1 month. DIAGNOSIS ASSESSMENT: The PE showed bilateral crackles on chest auscultation and a palpable fluctuant mass over the anterior chest wall. The chest and abdominal CT scan showed multiple abscess formations involving pulmonary, sternal, and paraspinal areas. The TEE being performed and an oscillating mass over the anterior and septal leaflets of the tricuspid valve and moderate tricuspid regurgitation. INTERVENTIONS: Only pharmacologic treatment without surgical interventions. OUTCOMES: Deceased, patient expired on day 4 after ED visit. CONCLUSION: This case arose as a sequela of staphylococcal endocarditis associated with persistent bacteremia and immunological dysregulation. The diagnosis of right-sided endocarditis is easily missing, multidisciplinary approach should be triggered as soon as possible, which might lead to a better outcome. Right-sided IE is still an important public health issue in southern Taiwan.

Objective: Strong earthquakes often cause massive structural and nonstructural damage, timely assessment of the catastrophe related massive casualty incidents (MCIs) for deploying rescue resource are critical in order to minimize ongoing fatalities. A magnitude 6.6 earthquake struck southern Taiwan on February 6, 2016 (the so-called 02/06 Meinong earthquake). It led to 117 deaths and 522 injuries. Advanced technologies including aerial devices and innovation concept were adopted for more effective rescue efforts. We would like to share our innovative concept in MCIs experienced in 02/06 Meinong earthquake in 2016. Methods: A collapsed building, Weiguan residential apartment complex, was the most devastating building collapsed in Tainan, resulting in 115 people killed. Regional Emergency Medical Operational Centers (REMOCs), supervised by Taiwan Ministry of Health and Welfare, were activated immediately and collaborated with Tainan City government command center to initiate emergency rescue reliefs. Results: We, for the first time, attempted to use cyber devices including an internet-protocol camera and a multi-rotor unmanned aerial vehicle (UAV) equipped with a high-resolution digital camera used to acquire imagery during the rescue operation. Moreover, a photo-realistic 3-D model reconstructed by the acquired UAV imagery could provide real-time information from UAV to rescue team leaders in remote location for effectively deploying medical posts and emergency resources at scene. Conclusion: We proposed the concept of real-time UAV imagery for reconstructing photo-realistic 3-D model, which might greatly improve prehospital emergency management after disaster.

Road traffic injuries (RTIs) are among the leading causes of injury and fatality worldwide. RTI casualties are continually increasing in Taiwan; however, because of a lack of an advanced method for classifying RTI severity data, as well as the fragmentation of data sources, road traffic safety and health agencies encounter difficulties in analyzing RTIs and their burden on the healthcare system and national resources. These difficulties lead to blind spots during policy-making for RTI prevention and control. After compiling classifications applied in various countries, we summarized data sources for RTI severity in Taiwan, through which we identified data fragmentation. Accordingly, we proposed a practical classification for RTI severity, as well as a feasible model for collecting and integrating these data nationwide. This model can provide timely relevant data recorded by medical professionals and is valuable to healthcare providers. The proposed model's pros and cons are also compared to those of other current models.

BACKGROUND: In Taiwan, the current status of family-witnessed resuscitation (FWR) and the factors associated with behavioural intentions to implement FWR have not been systematically examined using representative medical staff. AIM: We explored predictive factors for behavioural intentions to implement FWR among medical staff using constructs from the theory of planned behaviour. METHODS: A survey of 1605 medical staff from five hospitals in southern Taiwan was conducted. Data were collected using a researcher-made questionnaire containing theory of planned behaviour constructs and demographic items. The dependent variable was intention to implement FWR, and the independent variables were three theory of planned behaviour constructs (attitudes, subjective norms, and perceived behavioural control) and the demographic characteristics. A generalized estimating equation was used to identify factors associated with the behavioural intentions. RESULTS: In total, 1122 valid questionnaires revealed that only 3.7% of participants advocated FWR policies. The construct scores for intention to implement FWR were 2.96 (on a five-point Likert scale), and the theory of planned behaviour constructs that significantly predicted intention to implement FWR were positive attitudes and subjective norms ( p<0.001). Classification of hospitals ( p=0.018) and restrictive provisions for FWR ( p=0.004) were additional significant predictors of intention to implement FWR. Moreover, medical staff employed at regional hospitals demonstrated higher intentions, positive attitudes and subjective norms than did those employed at the medical centre. CONCLUSION: According to the findings of this study, it may be desirable for administrators to prioritize the implementation of the FWR policy in regional hospitals. We recommend affording the factors of positive attitudes and subjective norms high priority to improve the medical staff's behavioural intentions of FWR practice.

OBJECTIVES: To investigate the diagnostic value of first-pass myocardial perfusion defects visualised in non-gated high-pitch computed tomography angiography (CTA) in patients admitted to the emergency department (ED) for suspected aortic dissection. METHODS: We recruited 174 ED patients who underwent high-pitch CTA of the aorta because of suspected aortic dissection. We divided these patients into two groups (diseased and control groups) based on whether their clinical data fulfilled the third universal definition of acute myocardial infarction (AMI), specifically an increase in cardiac troponin (cTn) with at least one of the following: (a) symptoms of ischemia; (b) new ST-segment-T wave (ST-T) changes or new left bundle branch block (LBBB); (c) development of pathological Q wave; (d) new loss of viable myocardium or new regional wall motion abnormality; or (e) identification of an intracoronary thrombus by angiography or autopsy. Twenty-two patients with a clinical diagnosis of AMI were placed in the diseased group. Myocardial perfusion defects were evaluated qualitatively and quantitatively on the late arterial phase obtained 50 s post-threshold. RESULTS: Of the 22 patients with a final diagnosis of AMI, visually identifiable perfusion defects were observed in 12 patients. The sensitivity, specificity, negative predictive value, and positive predictive value of any perfusion defect for predicting AMI were 54.6%, 94.7%, 93.5%, and 60.0%, respectively. Quantitative analysis indicated that CT attenuation was significantly lower within perfusion defects than within the normal myocardium (67.6 ± 29.5 HU vs. 92.2 ± 19.7 HU; p < 0.001). CONCLUSIONS: In patients with acute chest pain, the presence of myocardial perfusion defect observed on nongated high-pitch CTA of the aorta can be used to identify individuals with AMI with high specificity, but low sensitivity.

Current anti-fibrotic effect of antioxidants in vivo is disappointing due probably to the fact that once liver fibrogenesis is established it is too advanced to be reversed by anti-oxidation mechanism. We consider antioxidant may only act on the early phase of fibrogenesis. Thus, we had previously established an early liver fibrosis animal model using an inducible expression vector (pPK9a), which contains TGF-ß gene and was hydro-dynamically transferred into mice to induce a transient liver fibrosis. TGF-ß1 has been well documented to up-regulate the expression of α2(1) collagen (Col 1A2) gene in the liver via the reactive oxygen species (ROS); the process triggers inflammation, leading to hepatic stellate cells (HSC) activation and liver fibrogenesis. Using our animal model and ROS, cyclooxygenase-2 (Cox-2) and Col 1A2 promoter assays as screening targets, we report here that a maleic acid derivative isolated from the Antrodia camphorata mycelium strongly decreases ROS production, promoter activity of Cox-2 and Col 1A2, intracellular calcium, expression of alpha-smooth muscle actin (α-SMA), Smad4-p-Smad2/3 co-localization in cell nucleus and the DNA binding activity of Sp1. Our results suggest that the maleic acid derivative prevents liver fibrosis at an early phase both in vitro and in vivo through the inhibition of ROS, inflammation and the activation of HSC.

BACKGROUND: Family presence during resuscitation is an emerging trend, yet it remains controversial, even in countries with relatively high acceptance of family presence during resuscitation among medical professionals. Family presence during resuscitation is not common in many countries, and medical professionals in these regions are unfamiliar with family presence during resuscitation. Therefore, this study predicted the medical professionals' intention to allow family presence during resuscitation by applying the theory of planned behaviour. DESIGN: A cross-sectional survey. SETTINGS: A single medical centre in southern Taiwan. PARTICIPANTS: Medical staffs including physicians and nurses in a single medical centre (n=714). METHODS: A questionnaire was constructed to measure the theory of planned behaviour constructs of attitudes, subjective norms, perceived behavioural control, and behavioural intentions as well as the awareness of family presence during resuscitation and demographics. In total, 950 questionnaires were distributed to doctors and nurses in a medical centre. RESULTS: Among the 714 valid questionnaires, only 11 participants were aware of any association in Taiwan that promotes family presence during resuscitation; 94.7% replied that they were unsure (30.4%) or that their unit did not have a family presence during resuscitation policy (74.8%). Regression analysis was performed to predict medical professionals' intention to allow family presence during resuscitation. The results indicated that only positive attitudes and subjective norms regarding family presence during resuscitation and clinical tenure could predict the intention to allow family presence during resuscitation. CONCLUSIONS: Because Family presence during resuscitation practice is not common in Taiwan and only 26.19% of the participants agreed to both items measuring the intention to allow family presence during resuscitation, we recommend the implementation of a family presence during resuscitation education program that will enhance the positive beliefs regarding family presence during resuscitation as they are a significant predictor of the intention to allow family presence during resuscitation. In addition, written policies and protocols for family presence during resuscitation are also needed to increase support from subjective norms regarding family presence during resuscitation practice.

OBJECTIVES: The purpose of this study was to determine whether the implementation of a standardized rapid sequence intubation (RSI) protocol easily accessed on the resuscitation cart increased the success rate of intubation and reduced intubation-related complications in the emergency department (ED). METHODS: This work was a retrospective study of patients who were intubated in the ED between February 2006 and June 2007. The RSI protocol and a dosage cross-table were attached to the resuscitation cart beginning in January 2007. Intubated patients before and after application of the protocol were sorted into two groups: pre-intervention and post-intervention. RESULTS: A total of 147 patients were enrolled in the study, including 72 patients in the pre-intervention group and 75 patients in the post-intervention group. After application of the standardized protocol prompted on the resuscitation cart. The adherence rates to pre-treatment agents (69% vs. 90%; p < 0.01) and neuromuscular blocking agents (NMBA) (72% vs. 90%; p < 0.01) significantly improved. The first-attempt success rate was 57 of 72 (79%) in the pre-intervention group versus 70 of 75 (93%) in the post-intervention group (p = 0.016). The time to intubation did not differ signifi cantly, but the preintervention group had a higher percentage of prolonged time to intubation (13% vs. 3%; p = 0.029). The implementation of a standardized RSI protocol did not induce signifi cant adverse effects. CONCLUSIONS: Our study demonstrated implementation of a standardized RSI protocol, improved clinician adherence to the RSI, increased success of first-attempt ED intubation and led to a decline in the rate of prolonged time to intubation.
RESUMEN
BACKGROUND: Sickness among field relief workers prompted us to develop strategies for preventing manpower loss. Most studies have focused on the preparedness and safety of medical responders in the prepared phase, but those parameters are lacking in the response phase. This study attempted to identify effective ways to prevent medical team members from acquiring acute diarrhea and upper respiratory tract infection (URI) based on our field reports. This was a retrospective cohort study. The 56 team members were from eight missions in total, including medial disaster relief and international humanitarian assistance, deployed between June 2007 and February 2010. The demographics of the participating members and their actions were examined for association with acute diarrhea and upper respiratory tract infection episodes using a mixed-effect logistic regression model. One member (7.0%) with acute diarrhea and 11 (26.1%) members without acute diarrhea took doxycycline. The relationship between doxycycline and acute diarrhea episodes was not statistically signifi cant. However, while 6 of 14 team members (42.9%) with acute diarrhea used hand sanitizer, 35 of 42 team members (83.3%) without diarrhea used hand sanitizer. Only hand sanitizer use was statistically related to the prevention of acute diarrhea and URI (p value = 0.021, 0.032). Hand sanitizer is suggested to protect medical teams from acute diarrhea and URI in such challenging environments. Chemoprophylaxis for malaria remains dependent on the area of deployment.

This study attempted to identify effective ways to prevent medical team members from acquiring acute diarrhea and upper respiratory tract infection (URI) based on our field reports. This was a retrospective cohort study. The 56 team members were from eight missions in total, including medial disaster relief and international humanitarian assistance, deployed between June 2007 and February 2010. The demographics of the participating members and their actions were examined for association with acute diarrhea and upper respiratory tract infection episodes using a mixed-effect logistic regression model. One member (7.0%) with acute diarrhea and 11 (26.1%) members without acute diarrhea took doxycycline. The relationship between doxycycline and acute diarrhea episodes was not statistically signifi cant. However, while 6 of 14 team members (42.9%) with acute diarrhea used hand sanitizer, 35 of 42 team members (83.3%) without diarrhea used hand sanitizer. Only hand sanitizer use was statistically related to the prevention of acute diarrhea and URI (p value = 0.021, 0.032). Hand sanitizer is suggested to protect medical teams from acute diarrhea and URI in such challenging environments. Chemoprophylaxis for malaria remains dependent on the area of deployment.

RESUMEN
The macrophage migration inhibitory factor (MIF), a pro-inflammatory cytokine, is deregulated in acute kidney injury (AKI) through an unknown mechanism. In the present study, we used a previously described mouse model of ascending urinary tract infection in which uropathogenic Escherichia coli (UPEC) were transurethrally inoculated to induce kidney infections. Here, we show that urinary MIF was upregulated during AKI while MIF was abundantly expressed in the renal cortical tubules and that UPEC infection caused a decrease in tubular MIF. Infections with UPEC in vitro caused MIF release in a cell type-dependent manner, which was independent of receptor-mediated internalization, signal transduction, and transcription. Indeed, UPEC infection-induced necrotic cell death in vitro and in vivo correlated with extracellular acidification and processed MIF secretion. These data suggest that MIF is released by necrotic renal cortical tubular cells during UPEC infection.

Conventional markers of kidney function that are familiar to clinicians, including the serum creatinine and blood urea nitrogen levels, are unable to reveal genuine injury to the kidney, and their use may delay treatment. Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine, and the predictive role and pathogenic mechanism of MIF deregulation during kidney infections involving acute kidney injury (AKI) are not currently known. In this study, we showed that elevated urinary MIF levels accompanied the development of AKI during kidney infection in patients with acute pyelonephritis (APN). In addition to the MIF level, the urinary levels of interleukin (IL)-1ß and kidney injury molecule (KIM)-1 were also upregulated and were positively correlated with the levels of urinary MIF. An elevated urinary MIF level, along with elevated IL-1ß and KIM-1 levels, is speculated to be a potential biomarker for the presence of AKI in APN patients.
