The potential risks to PPIs include hypomagnesemia and chronic kidney disease (CKD). Unlike a real-world electronic medical record (RW-EMR) with active-comparator design, claim databases and special population cohort with non-user design, using in previous studies, resulted in a wide range of strength of association with indication bias. This study aimed to measure the total effect of association between PPIs use and CKD incidence using Thai RW-EMR.Patients and Methods: A retrospective hospital-based cohort was applied into this study. Electronic medical records and administrative data of out- and inpatient were retrieved from October 1st, 2010 to September 30th, 2017. On-treatment with grace period as well as propensity score matching was used in data analysis. Cox proportional hazard models were applied to evaluate the PPIs-CKD association.Results: Of all 63,595 participants, a total of 59,477 new PPIs and 4118 Histamine 2-receptor antagonist (H2RA) users were eligible for follow-up. As compared with H2RA, the PPI users were non-elderly and more likely being female. The association of PPIs with CKD was statistically significant (adjusted hazard ratio [HR] = 3.753, 95% CI = 2.385– 5.905). The HR were not statistically different by concomitant use PPIs with NSAIDs and by medication possession ratio levels.Conclusion: The association between PPIs and CKD incidence was statistically significant in this hospital-based cohort. However, self-treatment with over-the-counter PPIs, as well as, smoking, drinking alcohol and body mass index could not be fully retrieved, affecting the estimation of treatment effect.Keywords: proton-pump inhibitors, chronic kidney disease, retrospective cohort, hospital-based medical database

The use of new psychoactive substances (NPSs) has markedly increased worldwide; thus, it is important to monitor NPS-related effects. The Taiwan Emergency Department Drug Abuse Surveillance (TEDAS) project aims to assess the patterns of recreational drug use in patients presenting to emergency departments (EDs) across the country. Here, we report the preliminary results of this project.This observational study included the collection and analysis of urine samples and assessment of the clinical presentation of patients from 79 EDs across Taiwan. Clinical features were recorded through a questionnaire filled by attending doctors or nurses who collected urine samples for clinical diagnosis. Urine samples were analyzed for 110 drugs and metabolites using electrospray ionization liquid chromatography-tandem mass spectrometry (LC-MS/MS).Between February and November 2019, a total of 2649 patients were enrolled for urine drug analysis. A total of 675 cases older than 12 years (males,The TEDAS project provides a nationwide epidemiological profile of recreational drug use in Taiwan. More than half of the recreational drugs were NPSs, which were comprehensively detected using LC-MS/MS.

Objectives: Chronic kidney disease (CKD) has emerged as a global health concern. Many studies have identified an association between hyperuricemia and CKD, and some studies have revealed that urate-lowering therapy (ULT) can attenuate CKD progression. However, only a few studies have explored the role of ULT in the prevention of new onset CKD. Methods: To compare the risk of incident CKD between users and nonusers of ULT in patients with gout, we conducted a 13-year population-based retrospective cohort study. Overall incidence of CKD was compared between 7126 ULT users and 7126 matched ULT nonusers. Results: The CKD incidence rate for both the users and nonusers of ULT was 1.7 per 100 person-years, after adjusting for sex, age, region of residence, comorbidities, and medications used. No significant difference in CKD risk (adjusted hazard ratio [aHR]: 0.97; 95% confidence interval [CI]: 0.88-1.07) was noted between the ULT users and nonusers. In the subgroup of patients with diabetes mellitus (DM) and without hypertension (HT), ULT tended to be associated with lower risk of incident CKD (aHR: 0.52; 0.95% CI: 0.28-0.97). Compared with the risk of new onset CKD in patients receiving xanthine oxidase inhibitors, those receiving uricosuric agents seemed to have a lower risk of developing CKD (aHR: 0.81, 95% CI: 0.67-0.99). Conclusion: This population-based cohort study indicated that ULT is not associated with lower risk of CKD development. However, in the subgroup of patients with DM and without HT, ULT is associated with significantly lower risk of incident CKD.

Pregnant and lactating women are vulnerable to iodine deficiency. This study was conducted to evaluate the iodine nutritional status of lactating women in northern Taiwan.Women recruited from Taipei Veterans General Hospital (TVGH) in 2019 provided a spot urine sample and completed a Food Frequency Questionnaire. The urinary iodine concentration (UIC) was measured by inductively coupled plasma mass spectrometry.The overall median UIC in 198 women was 120.4 μg/L, indicating a sufficient iodine status. Univariate analysis revealed a lower median UIC in women of younger age (p = 0.004), who were not taking multivitamins (p = 0.004), not on a postpartum nourishment diet (p = 0.04), and whose infant received more breast milk (p = 0.004). The median UIC was100 μg/L in the group aged 20 to 29 years (UIC: 74.4 μg/L) and in women whose infants' diet was composed of50% breast milk (UIC: 86.1 μg/L). A postpartum nourishment diet was followed by 73.7% (n = 146) of the women. Nevertheless, a significant decrease in the intake frequency of iodine-containing foods, including seaweeds (p0.001), seafood (p0.001), dairy products (p = 0.009), and multivitamins (p0.001) was observed compared with the intake noted in a previous survey of pregnant women in TVGH. Following multivariate analysis, only younger age (20-29 vs ≥30 years; odds ratio [OR]: 3.38; 95% confidence interval [CI]: 1.49-7.65), no use of multivitamin (OR: 1.89; 95% CI: 1.03-3.48), and infant diet composition (50% breast milk vs50% breast milk; OR: 2.93; 95% CI: 1.37-6.25) were independently associated with UIC100 μg/L.The results suggest that the iodine status in lactating women in northern Taiwan is adequate. However, iodine deficiency may continue to be present in certain subgroups, such as women of younger age and those who do not take multivitamins.

BACKGROUND Cancer is one of the leading causes of death worldwide. Despite the rapid evolution of cancer treatment, chemotherapy remains the mainstay in the management of cancer. Chemotherapy can result in various adverse drug reactions (ADRs), which may lead to hospitalization and even life-threatening side-effects. Hematologic ADRs are among the most severe forms of ADR following chemotherapy, as they generally lead to hospitalization. It is important to realize the predictors and outcome of hematologic ADRs in cancer patients. METHODS We conducted a hospital-based case-control study to include all the cancer patients who were hospitalized to receive chemotherapy in Taipei Veterans General Hospital during 2013. Among them the patients rehospitalized after chemotherapy due to neutropenia, leucopenia, or pancytopenia were identified as the study group. Control subjects consisted of hospitalized cancer patients who did not display the aforementioned ADRs. The study and control groups were numbered in the ratio of 1:4 and were age- and gender-matched. Their demographic and clinical characteristics were collected through chart review. Determinants of hematologic ADRs were then analyzed. RESULTS During the study period, we collected a total of 64 patients into the study group and 256 as control subjects. The mean length of hospitalization was 11 days in the study group of patients, which was 5 days longer than that in the control group (p < 0.001). Predictors of hematologic ADR-related hospitalization included history of hematologic ADRs, hypertension, cisplatin treatment, and a Charlson comorbidity score of 2 to 3. CONCLUSION Severe outcomes of hematologic ADRs may increase healthcare costs and decrease patient productivity. Therefore, the determinants of ADR-related hospitalization identified in this study may help improve the quality of healthcare for cancer patients.

BACKGROUND This population-based study was to investigate the potential risk factors of cardiotoxicity among colorectal cancer (CRC) patients treated with anticancer drugs. METHODS This was a retrospective cohort study using the National Health Insurance Research Database to identify the CRC patients receiving chemotherapy (CT) alone or CT combined with targeted therapies between 2000 and 2013. The patients enrolled were those who had the first diagnosis of CRC established ≥20 years and had no cancer history three years before the incident diagnosis of CRC. The outcomes of cardiotoxicity were defined by the diagnosis of acute myocarditis, cardiomyopathy, heart failure, hypertensive heart disease, and so on. RESULTS A total of 11 819 CRC patients were identified and 3781 were eligible; 556 (14.7%) patients developed cardiotoxicity after receiving anticancer treatment. Patients showed a similar risk of having primary outcome (hazard ratio [HR], 0.7; p = 0.3662) between CT and CT combined with targeted therapy groups, whereas the risk of developing secondary outcome was significantly different between the two groups (HR, 0.7; p = 0.0339). The hazard was found to be increased with age (60-69, HR 2.1, p = 0.0236; 70-79, HR 3.3, p = 0.0003; and ≥80, HR 3.7, p

The oxidative stress biomarker of urinary 8-hydroxy-2&prime, deoxyguanosine (8-OHdG) was reported to be changed in patients with allergic diseases. Measurement of urinary oxidative products is noninvasive. However, correlations between the severity levels of atopic diseases and oxidative stress remain unclear. This study aimed to investigate the association among urinary 8-OHdG, atopic dermatitis (AD), and the phenotypes of atopic diseases in children. In a nested case-control study, participants of kindergarten children were enrolled from the Childhood Environment and Allergic Diseases Study (CEAS). Urinary analyses and urinary 8-OHdG were performed on samples from 200 children with AD as cases and 200 age- and sex-matched controls. Our study presents the following main findings: (1) The urinary 8-OHdG levels were significantly higher in cases than controls. Higher urinary 8-OHdG levels were associated with the risk of AD in a dose-response-manner, (2) Children&rsquo, s AD history was associated with higher risks of asthma, allergic rhinitis, and night pruritus, (3) For children with AD, urinary 8-OHdG levels of &gt, 75th percentile were associated with higher risk of asthma, compared with the reference group of 0&ndash, 25th percentiles. In summary, this study provides better understanding of the underlying mechanisms of AD and urinary 8-OHdG by analyzing a large-scale sample survey in Taiwan.

A total of 186 patients withNo differences were observed between definite and suspected cases in terms of symptomatology and management. Of the 186 patients, 7 (3.8%) were asymptomatic, 179 (96.2%) experienced tissue swelling and pain, and 107 (57.5%) had local ecchymosis. Coagulopathy, thrombocytopenia, and renal impairment were found in 13 (7%), 19 (10.2%), and 7 (3.8%) patients, respectively. None of the patients required transfusion therapy or hemodialysis. Furthermore, no systemic bleeding or death occurred. Antivenom was administered to all 179 envenomed patients at a median of 1.5 h post-bite. The median total dose of the specific antivenom was 5.5 vials. In multivariate logistic regression analysis, finger as the bite site, bullae and blister formation, and wound infection were significantly associated with wound necrosis; whereas finger as the bite site and bullae and blister formation were related to debridement or finger/toe amputation.

Background: Carbon monoxide (CO) poisoning has recently become a serious health problem in some Asian countries, including Taiwan. The aims of this study are to evaluate the changing trend of CO poisoning and to demonstrate the association between myocardial injury and neurological sequelae of CO poisoning in Taiwan between 1990 and 2011. Methods: This retrospective cohort study included all eligible patients with acute CO poisoning reported to the Taiwan National Poison Control Center during the study period. The changing trend of CO poisoning and its impacts on the primary outcomes, i.e., persistent neurological sequelae (PNS) and delayed neurological sequelae (DNS), were then assessed. Results: 786 CO poisoned cases were reported. Among them, 467 cases were intentional. Intentional CO exposure started to become the major cause of CO poisoning in Taiwan in 2002. Increase in the number of intentional CO poisoning significantly correlated with the increase in the overall number of CO poisoning (r = 0.972, p

Background Increasing prevalence of allergic diseases has been matched by parallel trends in attention-deficit/hyperactivity disorder (ADHD). However, previous studies concerning the association between ADHD and allergic diseases have been inconsistent. Moreover, it is not clear whether this association is modified by allergic sensitization status. Therefore, we evaluated the association between allergic diseases, allergic sensitization, and ADHD in children. Methods We conducted a large-scale cross-sectional, population-based survey to investigate the relationship between allergic diseases, allergic sensitization, and ADHD. Children aged between 3 and 6 years were selected from kindergartens, and received skin prick tests (SPTs) for mite, cockroach, dog, milk, egg, and crab allergens. Information about allergic diseases, environmental exposures, and physician-diagnosed ADHD were collected. Multiple logistic regressions were performed to estimate the association between allergic diseases and ADHD, with adjustments made for potential confounders. Result A total of 2772 children were found to be eligible for analysis; of these 411 (14.8%) had atopic dermatitis (AD), 954 (34.4%) had allergic rhinitis (AR), 451 (16.3%) had asthma, and 28 (1.01%) had ADHD. Children who had AD and asthma with allergic sensitization were found to be at increased risk for ADHD, with adjusted ORs (95% CI) of 4.50 (1.28–15.86) and 3.65 (1.07–12.49). Children who had AR, allergic conjunctivitis, or food allergies were also related to ADHD, though failed to reach statistical significance. Conclusion Our results suggest that AD and asthma with allergic sensitization are associated with ADHD in children. As allergic sensitization is an increased factor of developing allergic diseases, early control of environmental and allergens exposure could help to modify the burden of ADHD.

Although specific antivenom is available in Taiwan, respiratory failure and general pain frequently accompany Bungarus multicinctus envenomation and there have been few reports on the management of B. multicinctus envenomation. We retrospectively analyzed 44 cases of B. multicinctus bite admitted to Taichung Veterans General Hospital (VGH) or to Taipei VGH. Demographic data, treatment, and outcome of patients with and without respiratory failure were compared. In this study, 20.5% patients had bites without noticeable signs or symptoms of significant envenoming, 27.3% developed respiratory failure, and 27.3% experienced general pain. Bivalent specific antivenom for B. multicinctus and N. atra was administered in all envenomed cases. Respiratory failure occurred 1.5-6.5 hours post-bite and general pain occurred 1-12 hours post-bite. Specific antivenom for B. multicinctus and N. atra at the recommended dose (i.e., 2-4 vials) might not effectively prevent respiratory failure and pain. Respiratory failure, general pain, and autonomic effects after B. multicinctus bite were probably caused, at least partly, by β-bungarotoxin. Although general weakness, ptosis, dysarthria, and dilated pupils were significantly associated with respiratory failure, their predictive value could not be accurately determined in such a retrospective study. Due to the rapid onset of respiratory failure, every suspected envenomed case thus should be closely monitored in the first few hours. We recommend the initial administration of four vials of antivenom in all envenomation cases, and a subsequent four vials be considered if the patient's condition is deteriorating. Prospective evaluation of the antivenom dosing regimen is urgently needed to improve B. multicinctus envenomation treatment.

Polycyclic aromatic hydrocarbons (PAHs) are known for their carcinogenic and teratogenic properties. However, little is known about the effect of PAH on our immune and respiratory systems. Hence, we investigated associations (1) between PAH exposure and IgE levels and asthma in children and (2) between PAH exposure and the oxidative stress marker 8OHdG potentially involved in disease pathogenesis stratifying by (3) sex-based differences. A total of 453 kindergarten children were recruited and provided samples. Urine biomarker of PAH exposure (1-OHP levels) was measured by UPLC-MS/MS and a marker of oxidative stress (8OHdG) was measured by ELISA. Serum IgE were assessed and information on asthma was collected. Associations between 1-OHP levels, 8OHdG, IgE and asthma were analyzed by multivariate linear and logistic regression. A mediation analysis was conducted to evaluate whether the risk of increased IgE and asthma related to PAH exposure is explained by 8OHdG changes. Urine 1-OHP levels were positively related to 8OHdG levels (per ln-unit: β = 0.30kU/l, p = 0.002). Similar results were also found for 1-OHP levels with IgE levels (per ln-unit: β = 0.27 kU/l, p = 0.027). 1-OHP levels (per ln-unit) were significantly associated with asthma, with an OR (95% CI) of 1.42 (1.18–1.70). In addition, 1-OHP levels were associated with asthma. It is estimated that 35% of the effect of PAH exposure on asthma is mediated by 8OHdG levels. Exposure to PAH may enhance oxidative stress and may induce asthma. The effect of PAH exposure on asthma may be mediated by oxidative stress.

Many studies have demonstrated that hyperuricemia is associated with hypertension (HTN) development, but few studies have explored whether urate-lowering therapy (ULT), which reverses hyperuricemia, decreases the risk of incident HTN. In this retrospective cohort study, we compared the risk of incident HTN of gout patients between those undergoing and not undergoing ULT. Risks of new-onset diabetes mellitus (DM) and chronic kidney disease (CKD) were also examined. In total, 2712 gout patients from 2000 to 2012 were enrolled. Overall incidence rates of HTN, DM, and CKD were compared between 1356 patients undergoing ULT recipients and 1356 matched control patients. After adjustment for sex, age, area, comorbidities, and drugs used, the incidence rates of HTN were 4.8 and 3.0 per 100 person years for non-ULT and ULT patients, respectively. ULT patients had a lower adjusted hazard ratio (aHR) of HTN (aHR: 0.64, 95% confidence interval [CI]: 0.54–0.75, p

Epidemiological studies have reported the relationship between bisphenol A (BPA) exposure and increased prevalence of asthma, but the mechanisms remain unclear. Here, we investigated whether BPA exposure and DNA methylation related to asthma in children. We collected urinary and blood samples from 228 children (Childhood Environment and Allergic Diseases Study cohort) aged 3 years. Thirty-three candidate genes potentially interacting with BPA exposure were selected from a toxicogenomics database. DNA methylation was measured in 22 blood samples with top-high and bottom-low exposures of BPA. Candidate genes with differential methylation levels were validated by qPCR and promoter associated CpG islands have been investigated. Correlations between the methylation percentage and BPA exposure and asthma were analyzed. According to our findings, MAPK1 showed differential methylation and was further investigated in 228 children. Adjusting for confounders, urinary BPA glucuronide (BPAG) level inversely correlated with MAPK1 promoter methylation (&beta, = &minus, 0.539, p = 0.010). For the logistic regression analysis, MAPK1 methylation status was dichotomized into higher methylated and lower methylated groups with cut off continuous variable of median of promoter methylation percentage (50%) while performing the analysis. MAPK1 methylation was lower in children with asthma than in children without asthma (mean &plusmn, SD, 69.82 &plusmn, 5.88% vs. 79.82 &plusmn, 5.56%) (p = 0.001). Mediation analysis suggested that MAPK1 methylation acts as a mediation variable between BPA exposure and asthma. The mechanism of BPA exposure on childhood asthma might, therefore, be through the alteration of MAPK1 methylation. The mechanism of BPA exposure on childhood asthma might, therefore, be through the alteration of MAPK1 methylation.

Background Venomous snakebites are common during hot seasons in Taiwan. However, rarely is venom spat directly into the subject's eyes, causing eye injury. Despite being uncommon, analytical data regarding venom-spit ophthalmia in Taiwan have been lacking. This study thus aimed to conduct an epidemiological survey on Naja atra venom-spit ophthalmia in Taiwan during the past decades to improve future care of such patients. Methods Registered records of cases with snake venom injuries at the Taiwan National Poison Control Center from 1990 to 2016 were retrospectively reviewed, enrolling those with records of cobra venom-spit eye injuries and excluding exotic species. Demographic data, clinical symptoms, snake species, ocular conditions, management, and outcomes were recorded and analyzed. Results A total of 39 cases suffering from Naja atra venom-spit ophthalmia were enrolled. The overall incidence rate was 1.6 cases per million people from 1990 to 2016. Among the included cases, most were unilaterally injured (82%), male (95%), aged 18 to 59 years (90%), injured during catching (51%), and injured in spring and summer (92%). Ocular symptoms occurred in 90% of the cases, majority of which included ocular pain (90%) and redness (85%). Conjunctivitis (67%) and corneal injury (59%) of involved eyes were common. Immediate water irrigations were done in all cases, most of whom received further topical eye drops, including antibiotics, corticosteroids, and vasoconstrictors. Although topical or intravenous antivenoms were administered in 11 cases, no obviously superior outcome was observed. Most cases (77%) were symptom free after the acute stage. Conclusion Although Naja atra venom-spit ophthalmia in Taiwan is uncommon, the risk for transient ocular symptoms and corneal/conjunctival injury does exists. Prompt ocular irrigation and professional ophthalmic care after envenomation help prevent serious ocular sequelae. Moreover, superior outcomes were not achieved with the use of antivenom. Nonetheless, further studies are required to clarify the role antivenoms play in venom-spit ophthalmia.

Pregnant women has long been considered one of the most vulnerable group for iodine deficiency. Previous nutritional survey revealed that the medium urinary iodine concentration (UIC) for women at child-bearing age of 15-44 years in Taiwan was 125 μg/L (1), which is insufficient for pregnant women. However, the actual iodine nutritional status in pregnancy is unknown. The primary objective of this study was to report for the first time the iodine nutritional status of pregnant women in Taiwan. In addition, dietary sources of iodine nutrition were investigated. A hospital-based cross-sectional survey of pregnant women was conducted in Taipei Veterans General Hospital in 2018. UIC of spot urine samples was determined by inductively coupled plasma mass-spectrometry. A food frequency questionnaire was delivered. The median UIC was 242 μg/L, while 20.4% and 7.3% of the population had median UIC below 100 μg/L and 50 μg/L, respectively. Consumption of seaweeds and agar were rare and the most frequently consumed iodine-containing foods were dairy products. The use of iodine-containing dietary supplements was common (51.5% of the women consume multivitamins especially designed for pregnancy every day). The questionnaire also revealed that 42.3% of the women were unaware of the salt product (iodized or not) in their households. The results indicate that the iodine status in pregnant women in Northern Taiwan is adequate. The difference in median UIC in pregnant women and women at child-bearing age generally may be related to the common use of iodine-supplement during pregnancy.

Objectives This study aimed to investigate the effects of a modified Hospital Elder Life Program (mHELP) on post-discharge cognition and physical function among older adults undergoing total knee arthroplasty (TKA), and to evaluate the incidence of postoperative delirium. Design Non-randomized intervention trial. Setting and participants A total of 140 patients aged 60 years and older scheduled for elective orthopedic surgery at our institution between August 2017 and December 2018 were included. Methods Ward-level stratification was used with one surgical ward receiving mHELP (intervention group), including orientation communication, early mobilization, vision/hearing impairment equipment, and dehydration prevention, and another ward providing usual care (control group). All participants were assigned to two surgical wards. Outcome measures were collected using MMSE telephone version (tMMSE), activities of daily living (ADL) and instrumental activities of daily living (IADL) instruments at 1, 6, and 12 months after discharge. Multiple linear regression analysis was used to measure effects of mHELP intervention on mean differences in tMMSE, ADL and IADL scores from baseline to 1-, 6- and 12-months. Results Effects of mHELP intervention significantly preserved cognitive function at 1 and 12 months, but not at 6 months, compared with controls, regardless of adjustments for confounders. However, no intervention effects were noted in ADL and IADL scores. Postoperative delirium in the whole cohort was 3.6 % (2.5 % in intervention group, 5.1 % in control group, P = 0.41). Conclusions mHELP intervention preserves post-discharge cognitive function, but has no notable effect on ADL and IADL function in older adults undergoing elective TKA surgery.

Chinese herbal medicines (CHMs) containing aristolochic acid (AA) are associated with chronic kidney disease (CKD), but some prescribed CHMs have been shown to possess renoprotective effects. We conducted a nationwide retrospective cohort study to delineate the role of prescribed CHMs on the CKD progression. Renoprotective CHM (RPCHM) was defined if a CHM contained dong chong xia cao (Cordyceps sinensis (Berk.) Sacc.), da huang (Rheum palmatum L), huang qi (Astragalus membranaceus), dan shen (Salvia miltiorrhiza Bge.), and dong quai (Angelica sinensis (Oliv.) Diels) or belonged to specific mixture herbal formulations (Yishen capsule, Saireito, or Wen Pi Tang). Subjects who had ever used AA-containing CHMs, had cancer or HIV prior to CKD diagnosis, or died within the first month of CKD diagnosis were excluded. A total of 11,625 patients were eligible subjects. The adjusted hazard ratio (aHR) for all-cause mortality was 0.6 (p < 0.001) and 0.6 (p = 0.013) among subjects receiving RPCHMs containing Angelica sinensis and those receiving other RPCHMs, respectively. For CKD-related mortality, the aHR among subjects receiving RPCHMs containing Angelica sinensis was 0.6 (p = 0.025). The use of specific RPCHMs, especially those that contained Angelica sinensis, was associated with a lower risk of mortality among CKD patients.

A total of 112 cases of Naja atra envenomation were examined at two referring hospitals: Taichung Veterans General Hospital in central Taiwan and Taipei Veterans General Hospital (VGH-TP) in northern Taiwan. Overall, 77% (86/112) of cases developed clinically suspected wound infections and 54% (61/112) required surgery secondary to tissue necrosis, finger or toe gangrene, and/or necrotizing fasciitis. Morganella morganii was the most abundant gram-negative bacterial strain isolated from bite wounds, followed by Proteus spp., Aeromonas hydrophila, Pseudomonas aeruginosa, and Providencia spp. in descending order; Enterococcus spp. were the most common gram-positive bacteria and Bacteroides spp. were the only anaerobic bacteria. A few episodes of bacteremia were caused by Bacteroides and Shewanella spp. There were no significant variations in the distribution of bacterial species between these two hospitals except for a higher incidence of M. morganii, Enterococcus spp., and polymicrobial infection observed at VGH-TP, which may have been related to variations in the fecal flora of prey and oral flora of individual snakes in different geographic areas in Taiwan. According to the susceptibility test involving various pathogens, first-line drug options for the management of N. atra snakebite wound infections may include monotherapy with ureidopenicillin or combination therapy with aminopenicillin and a third-generation cephalosporin or fluoroquinolone. A prospective evaluation of empiric antibiotic therapy for the management of N. atra snakebite should be considered.

Introduction Insomnia is a risk factor for hypertension and cardiovascular events, and this association is strongest for sleep-onset insomnia. However, little is known about insomnia on cardiovascular modulation, especially soon after morning awakening, the peak period of time for cardiovascular incidents. This study explored morning cardiovascular function in individuals with sleep-onset insomnia by analysing heart rate variability, blood pressure variability, and baroreflex sensitivity. Methods Sleep structure of the participants (15 good sleepers and 13 individuals with sleep-onset insomnia) was measured by laboratory polysomnography, followed by continuous recordings of the participant’s blood pressure and heart rate for 10 min in the morning. Results When compared to the good sleepers, the insomnia group showed significant reductions in total sleep time, a longer sleep-onset latency, and reduced sleep efficiency. The sleep structure, including durations of sleep stages, numbers of awakenings and arousal index did not differ between the groups. After morning awakening (averaged time: 12.33 ± 10.48 min), the shorter R-R intervals, lower total power, and lower high-frequency power of heart rate variability were observed among individuals with sleep-onset insomnia, compared with good sleepers. Elevated slopes of systolic and diastolic blood pressure, as well as lower baroreflex sensitivity, were also shown in the insomnia group. Indices of sympathetic activity, including low-frequency percentage of heart rate variability or low-frequency power of blood pressure variability, did not differ between the groups. Conclusion Weak vagal activity and blunted baroreflex sensitivity were evident among sleep-onset insomnia. These findings indicate difficulty in initiating sleep, without significant sleep fragmentation, can independently affect morning cardiovascular function. This study provides a possible link between sleep-onset insomnia and risk of cardiovascular events. Support N/A

Introduction:Datura and Brugmansia plants, especially Datura species, have been used for their hallucinogenic effects in the United States and Europe; whereas Datura plants have been used as a traditional medicine in many Asian countries. This study was conducted to better understand the pattern and outcome of Datura/Brugmansia plant related poisoning in Taiwan. Methods: This is a retrospective case series study of all cases with Datura/Brugmansia exposure reported to the Taiwan Poison Control Center between 1986 and 2015. Data for patients with relevant poisoning were reviewed and abstracted. Logistic regression analysis was used to identify potential predictors of the severity of poisoning; bivariate analysis was employed to assess the effectiveness of physostigmine in the treatment of Datura/Brugmansia poisoning. Results: A total of 203 cases involving 114 Datura exposures and 89 Brugmansia suaveolens exposures were eligible for analysis. Using Datura/Brugmansia for a medicinal purpose by the patients without consulting Chinese medicine practitioners was the most common reason of poisoning (81.2%); whereas only 2% of the patients were poisoned after medicinal use associated with the prescription from Chinese medicine practitioners. None of the 203 patients had used Datura/Brugmansia plant for recreational purpose. Most frequently observed clinical effect was mydriasis (53.2%), followed by confusion (40%), tachycardia (35.5%), dry mouth (35.5%), dizziness (34%), dry skin (32.5%), and delirium (31%). Seventy-three cases (36%) had severe effects; none of them died. Misidentification of the plants and ingestion of plant parts other than flowers were positively associated with the severity of poisoning. Forty patients (19.7%) received physostigmine therapy and patients receiving physostigmine had an earlier resolution of central nervous system toxicity than those who did not. Conclusions: Medicinal use without consulting Chinese medicine practitioners is the main reason for Datura/Brugmansia poisoning in Taiwan. Consumption of parts other than flowers and misidentification of the plants predicted the severity of poisoning in this study. Patients who received physostigmine appear to have earlier improvement in the central nervous system effects. No adverse events were reported from physostigmine administration.

Delayed neuropsychiatric sequelae (DNS) are serious complications of carbon monoxide poisoning; neuropsychiatric disorders can occur within a few days of recovery from acute poisoning. Hyperbaric oxygen therapy (HBOT) has been the main treatment of carbon monoxide (CO) poisoning and was recommended as the treatment choice for CO poisoning by the American Undersea and Hyperbaric Medical Society and the Tenth European Consensus Conference on Hyperbaric Medicine of the European Underwater and Baromedical Society. However, the optimal timing for commencing HBOT in patients with CO poisoning remains unknown. We therefore conducted a retrospective study in an attempt to target the optimal time of HBOT for DNS prevention.A retrospective review of patient files/medical records was conducted on all patients with CO poisoning admitted to the Emergency Department of Linkou Chang-Gung Memorial Hospital, Taiwan between January 1, 2009 and December 31, 2015. A total of 279 patients who received HBOT were eligible for further DNS detection. DNS was defined as the presence of one of the following neurological, cognitive, or psychological sequelae that were documented in the medical record during hospital stay or outpatient clinic follow-up for at least 6 months. A multivariable logistic regression analysis was employed to identify potential determinants of DNS after receiving HBOT for CO poisoning. A receiver operating characteristic (ROC) curve was used to analyse the influence of duration from CO exposure to HBOT on DNS development.A Glasgow coma score of9 (odds ratio [OR], 3.20; 95% confidence interval [CI], 1.19-8.60) and a longer duration from CO exposure to HBOT (OR, 1.06; 95% CI, 1.03-1.09) were associated with a higher risk of DNS. By contrast, the presence of multiple victims from the same incident was associated with a lower risk of DNS. The ROC curve for the duration between CO exposure and HBOT in predicting DNS development demonstrated an area under the curve of 0.638 (95% CI, 0.575-0.698). The optimal cut-off point according to the Youden index was 22.5 h, with a sensitivity of 41.7% and a specificity of 85.9%. We also stratified the duration from CO exposure to HBOT into 5 intervals (6 h, 6-11 h, 12-23 h, 24-47 h and ≥ 48 h) and revealed a trend of increasing DNS risk with time.We identified several potential predictors of DNS in patients with CO poisoning who received HBOT. Multivariable logistic regressions further revealed that longer duration from CO exposure to HBOT, loss of consciousness, and the presence of multiple victims were independent predictors of DNS development. HBOT should be performed as early as possible and preferably within 22.5 h after CO poisoning.

We analyze the time trends of hypoglycemia-related emergency department visits in Taiwan between 2000 and 2010, focusing on type 2 diabetic patients receiving antidiabetic agents.From a national dataset containing longitudinal medical claims of one million persons, we ascertained 4479 hypoglycemia-related emergency department visits from 3184 type 2 diabetic patients for analysis. We used negative binomial regression to calculate the incidence rate ratios (IRRs) for comparing event rates of hypoglycemia-related emergency department visits in different study periods.Rates of hypoglycemia-related emergency department visits increased 4.8 folds from year 2000 to 2010 (adjusted IRR 4.88, 95% CI 3.94-6.05, P0.001). Severe hypoglycemia requiring emergency department visits prevailed among women, older patients (≥ 65 years), and those not lived in the urban areas.Within a 10-year period, there was a substantial increase in the rates of hypoglycemia-related emergency department visits from type 2 diabetic patients in Taiwan. Appropriate risk management plans should be developed to prevent the occurrence of severe hypoglycemia in patients with type 2 diabetes in Taiwan.

1-Bromopropane (1-BP) is an alternative to ozone-depleting solvent that is used in degreasing, dry cleaning, spray adhesives, and aerosol solvents. Occupational exposure to 1-BP is associated with adverse peripheral sensory, motor, and central nervous system (CNS) effects. We report our Health Hazard and Medical Evaluation of 6 patients with neurotoxicity associated with occupational exposure to 1-BP. Case series and environmental evaluation. Six workers, 1 male and 5 female, were exposed to high ambient 1-BP concentrations while employed in a golf club cleaning factory. 1-BP was identified in the bulk solvent sample used by the workers and confirmed the workers' daily occupational exposure to 1-BP for 3-10 months. The major presenting symptoms were tingling pain, soreness in lower extremities, and paresthesia. N-acetyl-S-(n-propyl)-L-cysteine (AcPrCys), a 1-BP metabolite, was identified by LC/MS/MS in the urine (0.171-1.74 mg/g-Cr) of these workers 5-26 days following 1-BP exposure.An occupational outbreak of 1-BP poisoning occurred as a result of recurrent power outages, condenser, and exhaust fans malfunction, and inadequate personal protection. Occupational exposure to 1-BP may result in peripheral neuropathy as well as adverse CNS effects. Urine AcPrCys may be a specific biomarker for 1-BP exposure.
