RESUMEN

The development of alternative techniques to efficiently inactivate bacterial suspensions is crucial to prevent transmission of waterborne illness, particularly when commonly used techniques such as heating, filtration, chlorination, or ultraviolet treatment are not practical or feasible. We examine the effect of MHz-order acoustic wave irradiation in the form of surface acoustic waves (SAWs) on Gram-positive (Escherichia coli) and Gram-negative (Brevibacillus borstelensis and Staphylococcus aureus) bacteria suspended in water droplets. A significant increase in the relative bacterial load reduction of colony-forming units (up to 74%) can be achieved by either increasing (1) the excitation power, or, (2) the acoustic treatment duration, which we attributed to the effect of the acoustic radiation force exerted on the bacteria. Consequently, by increasing the maximum pressure amplitude via a hybrid modulation scheme involving a combination of amplitude and pulse-width modulation, we observe that the bacterial inactivation efficiency can be further increased by approximately 14%. By combining this scalable acoustic-based bacterial inactivation platform with plasma-activated water, a 100% reduction in E. coli is observed in less than 10 mins, therefore demonstrating the potential of the synergistic effects of MHz-order acoustic irradiation and plasma-activated water as an efficient strategy for water decontamination.

RESUMEN

Plasma treatment constitutes an efficient method for chemical-free disinfection. A spray-based system for dispensing plasma-activated aerosols onto surfaces would facilitate disinfection of complex and/or hidden surfaces inaccessible to direct line-of-sight (for example, UV) methods. The complexity and size of current plasma generators (for example, plasma jet and cometary plasma systems)-which prohibit portable operation, together with the short plasma lifetimes, necessitate a miniaturized in situ technique in which a source can be simultaneously activated and administered on-demand onto surfaces. Here, we demonstrate this possibility by combining two nanoscale technologies for plasma and aerosol generation into an integrated device that is sufficiently small and lightweight. Plasma is generated on a carpet of zinc oxide nanorods comprising a nanoneedle ensemble, which when raised to a high electric potential, constitutes a massive point charge array with near-singular electric fields to effect atmospheric breakdown. The plasma is then used to activate water transported through an underlying capillary wick, that is subsequently aerosolized under MHz-order surface acoustic waves. We show that the system, besides being amenable to miniaturization and hence integration into a chipscale device, leads to a considerable improvement in plasma-activation over its macroscale cometary discharge predecessor, with up to 20% and 127% higher hydrogen peroxide and nitrite ion concentrations that are respectively generated in the plasma-activated aerosols. This, in turn, leads to a 67% reduction in the disinfection time to achieve 95% bacterial load reduction, therefore demonstrating the potential of the technology as an efficient portable platform for on-demand field-use surface disinfection.

RESUMEN

Environmental contamination with Clostridioides difficile plays an important role in the transmission of C. difficile infection (CDI) in healthcare and long-term care facilities, which results in prolonged length of stay, higher risk of mortality and increased healthcare costs. Environmental cleaning bundles are introduced to improve environmental cleanliness. This study aimed to evaluate whether environmental cleaning bundles applied in hospital, community and long-term care settings reduce the incidence of healthcare-associated CDI compared with conventional cleaning practices. Relevant databases, websites and trial registration platforms were searched. Two reviewers conducted study screening and selection, data collection, risk of bias assessment and evidence quality assessment independently. Meta-analyses were conducted using Review Manager 5.3. Ten eligible studies [one randomized controlled trial (RCT) and nine non-RCTs] were included. No significant effect of environmental cleaning bundles on the CDI incidence rate was found [risk ratio (RR)=0.96, 95% confidence interval (CI) 0.71-1.29; studies=2; I2=49%; very low quality]. However, the removal of surface markers was improved significantly (RR=1.55, 95% CI 1.30-1.84; studies=3; I2=98%; very low quality), and the percentage of CDI rooms with positive cultures of C. difficile (RR=0.16, 95% CI 0.08-0.31; studies=4; I2=7%; moderate quality) was reduced significantly after the implementation of environmental cleaning bundles. Environmental cleaning bundles may consequently be helpful in improving the thoroughness of cleaning of environmental surfaces in hospital and long-term care settings. More well-conducted RCTs are expected to provide stronger evidence.

RESUMEN

The presence of reactive species in plasma-activated water is known to induce oxidative stresses in bacterial species, which can result in their inactivation. By integrating a microfludic chipscale nebulizer driven by surface acoustic waves (SAWs) with a low-temperature atmospheric plasma source, we demonstrate an efficient technique for in situ production and application of plasma-activated aerosols for surface disinfection. Unlike bulk conventional systems wherein the water is separately batch-treated within a container, we show in this work the first demonstration of continuous plasma-treatment of water as it is transported through a paper strip from a reservoir onto the chipscale SAW device. The significantly larger surface area to volume ratio of the water within the paper strip leads to a significant reduction in the duration of the plasma-treatment, while maintaining the concentration of the reactive species. The subsequent nebulization of the plasma-activated water by the SAW then allows the generation of plasma-activated aerosols, which can be directly sprayed onto the contaminated surface, therefore eliminating the storage of the plasma-activated water and hence circumventing the typical limitation in conventional systems wherein the concentration of the reactive species diminishes over time during storage, resulting in a reduction in the efficacy of bacterial inactivation. In particular, we show up to 96% reduction in Escherichia coli colonies through direct spraying with the plasma-activated aerosols. This novel, low-cost, portable and energy-efficient hybrid system necessitates only minimal maintenance as it only requires the supply of tap water and battery power for operation, and is thus suitable for decontamination in home environments.

RESUMEN

The aim of this study is to evaluate the clinical and economic burden of wound care in the Tropics via a 5-year institutional population health review. Within our data analysis, wounds are broadly classified into neuro-ischaemic ulcers (NIUs), venous leg ulcers (VLUs), pressure injuries (PIs), and surgical site infections (SSIs). Between 2013 and 2017, there were a total of 56 583 wound-related inpatient admissions for 41 461 patients, with a 95.1% increase in wound episodes per 1000 inpatient admissions over this period (142 and 277 wound episodes per 1000 inpatient admissions in 2013 and 2017, respectively). In 2017, the average length of stay for each wound episode was 17.7 days, which was 2.4 times that of an average acute admission at our institution. The average gross charge per wound episode was USD $12 967. Among the 12 218 patients with 16 674 wound episodes in 2017, 71.5% were more than 65 years of age with an average Charlson Comorbidity Index (CCI) of 7.2. Half (51.9%) were moderately or severely frail, while 41.3% had two or more wound-related admission episodes. In 2017, within our healthcare cluster, the gross healthcare costs for all inpatient wound episodes stand at USD $216 million within hospital care and USD $596 000 within primary care. Most NIU patients (97.2%) had diabetes and they had the most comorbidities (average CCI 8.4) and were the frailest group of patients (44.9% severely frail). The majority of the VLU disease burden was at the specialist outpatient setting, with the average 1-year VLU recurrence rate at 52.5% and median time between healing and recurrence at 9.5 months. PI patients were the oldest (86.5% more than 65 years-old), constituted the largest cohort of patients with 3874 patients at an incidence of 64.6 per 1000 admissions in 2017, and have a 1-year all-cause mortality rate of 14.3%. For SSI patients, there was a 125% increase of 14.2 SSI wound episodes per 1000 inpatient admissions in 2013 to 32.0 in 2017, and a 413% increase in wound-related 30-day re-admissions, from 40 in 2013 (4.1% of all surgeries) to 205 (8.3% of all surgeries) in 2017. The estimated gross healthcare cost per patient ranges from USD $15789-17 761 across the wound categories. Similar to global data, there is a significant and rising trend in the clinical and economic burden of wound care in Tropics.

RESUMEN

Background: The ICD-11 classifies posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as two distinct diagnoses. Few studies have tested the validity of ICD-11 CPTSD in non-Western settings, particularly in Asia. Objective: This study assessed the factorial, concurrent, and discriminant validity of CPTSD symptoms with four samples of young adults from mainland China, Hong Kong, Japan, and Taiwan. Method: Young adults aged 18-24 years were recruited by convenience sampling and provided their data anonymously online. Study measures included the International Trauma Questionnaire (ITQ) to measure PTSD and CPTSD, and measures of childhood adversity, depression, anxiety, age, and sex. Confirmatory factor analysis (CFA) was performed for each sample to evaluate the validity of two CPTSD measurement models. Structural equation modelling (SEM) was used to determine the multivariate associations between study variables for the full sample. Results: A total of 1,346 young adults completed the survey. CFA showed both models of CPTSD examined fit the data well across all four samples. SEM findings showed that number of childhood adversities significantly associated with both PTSD and CPTSD factors; depression significantly associated with CPTSD factors but not PTSD, whereas anxiety significantly associated with both. Conclusions: Study findings provide evidence for PTSD and CPTSD as separate and valid diagnoses in Asia. More cross-cultural comparisons are needed to understand whether risks for either condition differ by geographical or sociocultural norms.


Antecedentes: La CIE-11 clasifica el trastorno de estrés postraumático (TEPT) y el trastorno de estrés postraumático complejo (TEPT-C) como dos diagnósticos distintos. Pocos estudios han probado la validez del TEPT-C de la CIE-11 en escenarios no occidentales, particularmente en Asia.Objetivo: Este estudio evaluó la validez factorial, concurrente y discriminante de los síntomas de TEPT-C de 4 muestras de adultos jóvenes de China continental, Hong Kong, Japón y Taiwán.Método: Fueron reclutados adultos jóvenes entre 18 y 24 años de edad a través de una muestra por conveniencia y proveyeron sus datos en forma anónima en línea. Las mediciones del estudio incluyeron el Cuestionario Internacional de Trauma (ITQ por sus siglas en inglés) para medir TEPT y TEPT-C y mediciones de adversidad en la infancia, depresión, ansiedad, edad y sexo. Se realizó el análisis factorial confirmatorio (CFA por sus siglas en inglés) para cada muestra para evaluar la validez de los dos modelos de medición de TEPT-C. Se usó el modelado de ecuaciones estructurales (SEM por sus siglas en inglés) para determinar las asociaciones multivariadas entre las variables del estudio para la muestra completa.Resultados: un total de 1.346 adultos jóvenes completaron la encuesta. La CFA mostró que ambos modelos de TEPT-C examinados se ajustan bien los datos en las cuatro muestras. Los hallazgos del SEM mostraron que el número de adversidades en la infancia se asociaba significativamente tanto con los factores de TEPT y TEPT-C; la depresión se asociaba significativamente para TEPT-C pero no para TEPT; mientras que la ansiedad se asociaba significativamente con ambos.Conclusiones: los hallazgos del estudio proveen evidencia para TEPT y TEPT-C como dos diagnósticos separados y válidos en Asia. Se necesitan más comparaciones transculturales para comprender si los riesgos de cualquiera de estas condiciones difieren geográficamente o por normas socioculturales.

RESUMEN

INTRODUCTION: Adverse childhood experiences (ACEs) constitute a significant global mental health burden. Prior studies typically investigated the impact of ACEs on mental health using a cumulative risk approach; most ACEs studies were also conducted in Western settings. PURPOSE: This study aimed to examine ACEs using a pattern-based approach and assess their associations with mental health outcomes by early adulthood in East Asia. METHODS: The present study included measures of exposure to 13 categories of ACEs, depression, anxiety, maladjustment, and posttraumatic stress in a sample of 1346 university students from Hong Kong, China, Taiwan, and Japan. RESULTS: Latent class analysis indicated three distinct patterns of ACE exposure: Class 1: Low ACEs (76.0%); Class 2: Household Violence (20.6%); and Class 3: Household Dysfunction (3.4%). Those representing Class 3 had significantly more ACEs compared with those in Classes 1 or 2. Controlling for age and sex, those in Class 2 reported significantly higher depression and maladjustment symptoms compared with those in Class 1; both Classes 2 and 3 had significantly higher anxiety symptoms and odds for meeting diagnostic criteria for posttraumatic stress disorders compared with those in Class 1. CONCLUSIONS: Study findings suggest that young adults' mental health, at least under certain contexts, is more closely linked with the nature and pattern of ACE co-occurrence, rather than the number of ACEs.

RESUMEN

KHC-4 is a 2-phenyl-4-quinolone analogue that exhibits anticancer activity. Aberrant activation of ß-catenin signaling contributes to prostate cancer development and progression. Therefore, targeting ß-catenin expression could be a useful approach to treating prostate cancer. We found that KHC-4 can inhibit ß-catenin expression and its signaling pathway in DU145 prostate cancer cells. Treatment with KHC-4 decreased total ß-catenin expression and concomitantly decreased ß-catenin levels in both the cytoplasm and nucleus of cells. KHC-4 treatment also inhibited ß-catenin expression and that of its target proteins, PI3K, AKT, GSK3ß and TBX3. We monitored the stability of ß-catenin with the proteasomal inhibitor, MG132, in DU145 cells and found that MG132 reversed KHC-4-induced proteasomal ß-catenin degradation. We verified CDK1/ß-catenin expression in KHC-4 treated DU145 cells. We found that roscovitine treatment reversed cell proliferation by arresting the cell cycle at the G2/M phase and ß-catenin expression caused by KHC-4 treatment. We suggest that KHC-4 inhibits ß-catenin signaling in DU145 prostate cancer cells.

RESUMEN

BACKGROUND: Valproic acid (VPA) has shown potent anti-inflammatory effect and attenuates acute lung injury. AIM: To determine whether the use of VPA is associated with a decreased risk of acute respiratory failure (ARF) in patients with subarachnoid hemorrhage (SAH). DESIGN: The Taiwan National Health Insurance Research Database was used to analyse all patients newly diagnosed with SAH from 2000 to 2010. The VPA users were matched for age, gender and index date in 1:2 ratios with randomly selected non-VPA users as a comparison group. METHODS: Multivariate Cox regression was used to identify the predictors of ARF and to compare the incidence rates of ARF among SAH patients using and not using VPA. RESULTS: The study cohort included 16 228 newly diagnosed SAH patients, from which 521 VPA users and 1042 matched non-VPA-exposed individuals were selected. In the VPA-treated cohort and the non-VPA-treated cohort, 117 and 289 patients developed ARF, respectively. Any use of VPA was associated with a 16% decreased risk of ARF requiring mechanical ventilation in 30-day tracking of the SAH patients (adjusted hazard ratio [HR], 0.840, 95% confidence interval [CI], 0.676-0.945). Age, sepsis and pneumonia were identified as independent predictors of ARF in patients with SAH. After stratification, VPA users showed a lower risk of ARF among SAH patients complicated with pneumonia compared with non-users of VPA (adjusted HR, 0.816, 95% CI, 0.652-0.921). CONCLUSIONS: Any use of VPA was associated with a reduced risk of ARF in patients with SAH. VPA may be beneficial for decreasing the risk of pneumonia-induced ARF in patients with SAH.

RESUMEN

Although substantial progress has been made in the treatment of B-cell acute lymphoblastic leukemia (B-ALL), the prognosis of patients with either refractory or relapsed B-ALL remains dismal. Novel therapeutic strategies are needed to improve the outcome of these patients. KPT-9274 is a novel dual inhibitor of p21-activated kinase 4 (PAK4) and nicotinamide phosphoribosyltransferase (NAMPT). PAK4 is a serine/threonine kinase that regulates a variety of fundamental cellular processes. NAMPT is a rate-limiting enzyme in the salvage biosynthesis pathway of nicotinamide adenine dinucleotide (NAD) that plays a vital role in energy metabolism. Here, we show that KPT-9274 strongly inhibits B-ALL cell growth regardless of cytogenetic abnormalities. We also demonstrate the potent in vivo efficacy and tolerability of KPT-9274 in a patient-derived xenograft murine model of B-ALL. Interestingly, although KPT-9274 is a dual PAK4/NAMPT inhibitor, B-ALL cell growth inhibition by KPT-9274 was largely abolished with nicotinic acid supplementation, indicating that the inhibitory effects on B-ALL cells are mainly exerted by NAD+ depletion through NAMPT inhibition. Moreover, we have found that the extreme susceptibility of B-ALL cells to NAMPT inhibition is related to the reduced cellular NAD+ reserve. NAD+ depletion may be a promising alternative approach to treating patients with B-ALL.

RESUMEN

Metal-phenolic networks (MPNs) are a versatile class of self-assembled materials that are able to form functional thin films on various substrates with potential applications in areas including drug delivery and catalysis. Different metal ions (e.g., FeIII, CuII) and phenols (e.g., tannic acid, gallic acid) have been investigated for MPN film assembly; however, a mechanistic understanding of the thermodynamics governing MPN formation remains largely unexplored. To date, MPNs have been deposited at low ionic strengths (<5 mM), resulting in films with typical thicknesses of ∼10 nm, and it is still unclear how a bulk complexation reaction results in homogeneous thin films when a substrate is present. Herein we explore the influence of ionic strength (0-2 M NaCl) on the conformation of MPN precursors in solution and how this determines the final thickness and morphology of MPN films. Specifically, the film thickness increases from 10 nm in 0 M NaCl to 12 nm in 0.5 M NaCl and 15 nm in 1 M NaCl, after which the films grow rougher rather than thicker. For example, the root-mean-square roughness values of the films are constant below 1 M NaCl at 1.5 nm; in contrast, the roughness is 3 nm at 1 M NaCl and increases to 5 nm at 2 M NaCl. Small-angle X-ray scattering and molecular dynamics simulations allow for comparisons to be made with chelated metals and polyelectrolyte thin films. For example, at a higher ionic strength (2 M NaCl), sodium ions shield the galloyl groups of tannic acid, allowing them to extend away from the FeIII center and interact with other MPN complexes in solution to form thicker and rougher films. As the properties of films determine their final performance and application, the ability to tune both thickness and roughness using salts may allow for new applications of MPNs.

RESUMEN

BACKGROUND: Sleep-related movement disorders (SRMD) have been shown to increase the risk of cardiovascular diseases. However, the relationship between SRMD and stroke remains unclear. AIM: To explore the relationship between SRMD and stroke in the general population. DESIGN: Two cohorts of patients with SRMD and without SRMD were followed up for the occurrence of hemorrhagic and ischemic stroke. METHODS: The study cohort enrolled 604 patients who were initially diagnosed as SRMD between 2000 and 2005. 2,416 age- and sex-matched patients without prior stroke were selected as the comparison cohort. A Cox-proportional hazard regression analysis was performed for multivariate adjustment. RESULTS: Patients with SRMD had a higher risk for developing all-cause stroke [adjusted hazard ratio (HR) = 2.29, 95% confidence interval (CI) = 1.42-3.80]. Patients of below 45 years old had the greatest stroke risk (HR = 4.03, 95% CI = 3.11-5.62), followed by patients aged ≥65 years (HR = 2.64, 95% CI = 1.12-3.44) and 45-64 years (HR = 1.07, 95% CI = 1.02-1.71). The age-stratified analysis suggested that the increased risk of hemorrhagic stroke was more significant than ischemic stroke among all age groups. Furthermore, males with SRMD were at greater risk to develop all-cause stroke (HR = 2.98, 95% CI = 1.74-4.50) than that of females (HR = 1.94, 95% CI = 1.01-3.77). CONCLUSIONS: Patients with SRMD were found to have an increased risk of all-cause stroke along with a higher possibility of hemorrhagic stroke over ischemic stroke.

RESUMEN

BACKGROUND: We aimed to test a mindfulness-based psychoeducation group (MBPEG), v. a conventional psychoeducation group (CPEG) v. treatment as usual (TAU), in patients with schizophrenia-spectrum disorders over a 24-month follow-up. METHOD: This single-blind, multi-site, pragmatic randomized controlled trial was conducted in six community treatment facilities across three countries (Hong Kong, mainland China and Taiwan). Patients were randomly allocated to one of the treatment conditions, and underwent 6 months of treatment. The primary outcomes were changes in duration of re-hospitalizations and mental state (Positive and Negative Syndrome Scale; PANSS) between baseline and 1 week, and 6, 12 and 18 months post-treatment. RESULTS: A total of 300 patients in each country were assessed for eligibility between October 2013 and 30 April 2014, 38 patients per country (n = 342) were assigned to each treatment group and included in the intention-to-treat analysis. There was a significant difference in the length of re-hospitalizations between the three groups over 24 months (F 2,330 = 5.23, p = 0.005), with MBPEG participants having a shorter mean duration of re-hospitalizations than those in the other groups. The MBPEG and CPEG participants had significant differential changes in proportional odds ratios of complete remission (all individual PANSS items <3) over the 24-month follow-up (37 and 26%, respectively), as opposed to only 7.2% of the TAU group (χ2 = 8.9 and 8.0, p = 0.001 and 0.003, relative risk = 3.5 and 3.1, 95% confidence interval 2.0-7.2 and 1.6-6.3). CONCLUSIONS: Compared with TAU and CPEG, MBPEG improves remission and hospitalization rates of people with schizophrenia spectrum disorders over 24 months.

RESUMEN

BACKGROUND: Recent literature has suggested that relaxation activities can reduce the challenging behaviours of people with intellectual disabilities, particularly in severe and profound grades, due to the counteractive effect of muscle relaxation on emotional frustration or psychological distress. Despite having inconclusive evidence, multisensory environment (MSE) and massage therapy (MT) are the commonly used approaches to relaxation among these people. However, these two approaches have not yet practised or tested in combination for reducing these people's challenging behaviours. METHODS: A preliminary clinical efficacy trial was conducted to evaluate the effects of MT, MSE and their combined use for residents with intellectual disabilities in a long-term care facility on reducing their challenging behaviours. Eligible residents were recruited and randomly assigned to one of the four study groups (n = 11-12 per group), that is, MT in MSE, MSE alone, MT alone or usual care, for a 10-week intervention after a 1-month washout period. Outcome measures, including the Behaviour Problem Inventory, pulse and respiration rates, Behaviour Checklist and Alertness Observation Checklist, were assessed at recruitment and immediately following the interventions. RESULTS: A total of 42 participants (17 men and 25 women) completed the study. There were no significant differences in frequency and severity of challenging behaviours and most of the outcome measures between the four groups at post-test. Nevertheless, there were statistical significant differences on the active and inactive state (Alertness Observation Checklist) between the three treatment and control groups. Many participants in the three treatment groups changed from an active to inactive state (i.e. reduced activity levels) throughout the interventions, especially the MT in MSE. Such inactivity might suggest the participants' brief exhaustion followed by a period of alertness during the treatment activities. But their attention span and social contact to the immediate environment could still be maintained. CONCLUSIONS: Participants of MT in multisensory environment acquired more inactive state than the other study groups. This inactive state indicates a state of 'passive alertness', which is more likely in a relaxing manner.

BACKGROUND: Electroconvulsive therapy (ECT) remains irreplaceable in the treatment of several psychiatric conditions. However, evidence derived using data from a national database to support its safety is limited. The aim of this study was to investigate in-hospital mortality among patients with psychiatric conditions treated with and without ECT. METHODS: Using data from the Taiwan National Health Insurance Research Database from 1997 to 2013, we identified 828,899 inpatients with psychiatric conditions, among whom 0.19% (n=1571) were treated with ECT. RESULTS: We found that ECT recipients were more frequently women, were younger and physically healthier, lived in more urbanized areas, were treated in medical centers, and had longer hospital stays. ECT recipients had lower odds of in-hospital mortality than did those who did not receive ECT. Moreover, no factor was identified as being able to predict mortality in patients who underwent ECT. Among all patients, ECT was not associated with in-hospital mortality after controlling for potential confounders. CONCLUSION: ECT was indicated to be safe and did not increase the odds of in-hospital mortality. However, ECT appeared to be administered only on physically healthy but psychiatrically compromised patients, a pattern that is in opposition with the scientific evidence supporting its safety. Moreover, our data suggest that ECT is still used as a treatment of last resort in the era of modern psychiatry.

RESUMEN

BACKGROUND: Sepsis will induce stroke, new-onset atrial fibrillation (AF) increase ischemic stroke (IS) in in-hospitalization and long-term period after sepsis. Physicians must alert this condition and given suitable treatment. AIM: The associated of IS and new-onset AF in septicemia survivors after discharge have to be evaluated. DESIGN: The inpatient data was used of the Taiwan National Health Insurance Database (NHIRD) in 2010. We identified patients suffered their first occurrence of septicemia (International Classification of Disease, Ninth Revision, Clinical Modification [ICD-9-CM] is 038, 003.1, 036.1) and excluded less than 18 years old. Patients had AF (ICD-9-CM to 427.3×) during the same admission or after septicemia hospitalization discharged were defined as new-onset AF. The outcome was IS happened after septicemia discharge (ICD-9-CM as 433-437). METHODS: The factors related to IS after septicemia survival were established using multivariate logistic regression with forward stepwise selection. RESULTS: There were 1286 new-onset AF and 1026 IS happened after septicemia discharge. The crude odds ratio (OR) were 3.88 (95% confidence interval [C.I.]: 1.69-8.89) and 1.62 (95% C.I.: 1.14-2.3) in middle-aged and elderly septicemia survivors with new-onset AF induced IS. The risk of IS after septicemia survivors was noticed adjusted OR 1.74 (95% C.I.: 1.26-2.41) for new-onset AF. CONCLUSION: The middle-aged and elderly septicemia survivors suffered from new-onset AF had increased incidence of IS within three months. New-onset AF was a mediator factor of IS in septicemia survivors of Asian population.
