Association between statin therapy and long-term clinical outcomes in patients with stable coronary disease undergoing percutaneous coronary intervention.

This longitudinal cohort study examined the long-term effect of statin therapy on clinical outcomes in patients undergoing percutaneous coronary intervention (PCI). A total of 1760 patients with stable coronary artery disease (CAD) were divided by receipt of statin therapy or not after index PCI. Baseline clinical characteristics, risk factors, angiographic findings, and medications after interventional procedure were assessed to compare long-term clinical outcomes between groups. Predictors for all-cause death and major adverse cardiovascular events (MACE), including myocardial infarction (MI), cardiovascular death, and repeated PCI procedures, were also analyzed. The statin therapy group had higher average serum cholesterol and more elevated low-density lipoprotein cholesterol (LDL-C) than the non-statin therapy group (189.0 ± 47.9 vs 169.3 ± 37.00 mg/dl, 117.2 ± 42.6 vs 98.7 ± 31.8 mg/dl, respectively, both P < 0.001). The non-statin group had higher rates of all-cause death and cardiovascular death compared to statin group (both P < 0.001). After adjustment for age, diabetes, and chronic kidney disease, Cox proportion hazard analysis revealed statin use significantly reduced all-cause death and repeated PCI procedure (hazard ratio: 0.53 and 0.69, respectively). Statin use seemed not reduce the hazard of cardiovascular death or MI in patients with stable CAD after PCI; however, statin therapy still was associated with reduced rates of all-cause death and repeat PCI procedure.

Treatment of Undifferentiated Embryonal Sarcoma of the Liver in Children.

Undifferentiated embryonal sarcoma of the liver is a rare mesenchymal tumor with a highly malignant potential. It occurs almost exclusively in the pediatric population and typically has a poor outcome. Although previous studies have reported dismal prognoses, recent advances in combined treatment modalities, e.g., surgery and chemotherapy, have given cause for optimism. Even in those diseases not amenable to complete surgical resection or refractory diseases, other treatment modalities, such as liver transplant, have yielded promising results. This paper provides a review of the current treatment modalities for hepatic undifferentiated embryonal sarcoma in children.

Risk Factors for Urinary Tract Infections in Children with Hematuria in the Emergency Department.

INTRODUCTION: Hematuria is a worrisome symptom in children and is sometimes associated with urinary tract infections (UTIs). This study aimed to identify useful clinical factors that can predict UTIs in hematuria patients without pyuria in the pediatric emergency department (ED). METHODS: We retrospectively recruited patients with hematuria from the pediatric ED. Clinical symptoms, urine biochemistry and microscopic examination results, and blood laboratory tests were analyzed to identify the predictors of UTIs. Patients were divided into the verbal group (age ≥ 2 years) and non-verbal group (age < 2 years) for identifying predictors of UTIs. Causes of hematuria were also investigated. RESULTS: A total of 161 patients with hematuria without pyuria were evaluated. Among symptoms, dysuria was significantly correlated with UTIs. Regarding urine biochemistry data, urine esterase and urine protein > 30 mg/dl were found to be significant parameters for predicting UTIs, while urine esterase and urine nitrite showed significant differences in children with age < 2 years. In the urine microscopic examinations, urine red blood cells (RBC) > 373/µL in children aged ≥ 2 years and urine RBC > 8/µL in children aged < 2 years were associated with UTIs. In addition, UTIs and urinary tract stones were found to be the top two causes of hematuria. CONCLUSIONS: Dysuria, urine esterase, urine nitrite, and urine protein may be useful parameters for predicting UTIs in pediatric patients with hematuria but no pyuria in the ED. In addition, a UTI was the most commonly identified etiology of hematuria without pyuria, followed by urinary tract stones.

Advancements in Allergen Immunotherapy for the Treatment of Atopic Dermatitis.

Atopic dermatitis (AD) is a chronic inflammatory skin condition that affects individuals of all age groups, manifesting as a spectrum of symptoms varying from mild to severe. Allergen immunotherapy (AIT) involves the administration of allergen extracts and has emerged as a potential treatment strategy for modifying immune responses. Its pathogenesis involves epidermal barrier dysfunction, microbiome imbalance, immune dysregulation, and environmental factors. Existing treatment strategies encompass topical steroids to systemic agents, while AIT is under investigation as a potential immune-modifying alternative. Several studies have shown reductions in the severity scoring of atopic dermatitis (SCORAD) scores, daily rescue medication use, and visual analog scale (VAS) scores following AIT. Biomarker changes include increased IgG4 levels and decreased eosinophil counts. This review provides valuable insights for future research and clinical practice, exploring AIT as a viable option for the management of AD.

Psychological disorders and suicide attempts in youths during the pre-COVID and post-COVID era in a Taiwan pediatric emergency department.

Background: The COVID-19 pandemic has had a significant impact on pediatric patients, increasing their vulnerability to psychological fragility. The aim of this study was to investigate the epidemiology and clinical spectrum of pediatric psychological fragility and suicide attempts in the emergency department (ED) before and after the onset of the COVID-19 outbreak. Methods: A total of 340 pediatric patients admitted to the ED for psychological fragility between 2019 and 2022 were retrospectively collated and categorized according to three periods: pre pandemic, pandemic, and post pandemic. Epidemiological and clinical information were analyzed and compared among the three groups. Moreover, patients with suicidal ideation or suicidal attempts and types of substance use disorders in children with suicidal attempts sent to the ED were analyzed. Results: The proportion of psychological fragility increased during the pandemic period (0.4%) and the post-pandemic period (0.8%) compared to that in the pre-pandemic period (0.28%). Suicide ideation was the highest before the pandemic period (0.04%), while suicidal attempts were the highest in the post pandemic period (0.42%). Significantly elevated trends in suicide attempts involving overdose and injury were observed among the three groups (p < 0.05). Intensive care unit (ICU) admission rates increased significantly after the COVID-19 outbreak (p < 0.05), and major depressive disorder was the most common psychological fragility in the ED in all three groups. Conclusion: An increase in the proportion of pediatric psychological fragility in the ED was noted in the post pandemic period than before or during the pandemic. With higher rates of ICU admissions and an increase in suicide attempts among children and adolescents during the pandemic compared to before or after the pandemic, it is of utmost importance to provide mental health support to this vulnerable population in order to prevent suicide attempts in the event of a new global outbreak of infectious diseases.

Stem Cell Therapy in Children with Traumatic Brain Injury.

Pediatric traumatic brain injury is a cause of major mortality, and resultant neurological sequelae areassociated with long-term morbidity. Increasing studies have revealed stem cell therapy to be a potential new treatment. However, much work is still required to clarify the mechanism of action of effective stem cell therapy, type of stem cell therapy, optimal timing of therapy initiation, combination of cocurrent medical treatment and patient selection criteria. This paper will focus on stem cell therapy in children with traumatic brain injury.

Mesenchymal Stem Cells in the Treatment of COVID-19.

Since the emergence of the coronavirus disease 2019 (COVID-19) pandemic, many lives have been tragically lost to severe infections. The COVID-19 impact extends beyond the respiratory system, affecting various organs and functions. In severe cases, it can progress to acute respiratory distress syndrome (ARDS) and multi-organ failure, often fueled by an excessive immune response known as a cytokine storm. Mesenchymal stem cells (MSCs) have considerable potential because they can mitigate inflammation, modulate immune responses, and promote tissue regeneration. Accumulating evidence underscores the efficacy and safety of MSCs in treating severe COVID-19 and ARDS. Nonetheless, critical aspects, such as optimal routes of MSC administration, appropriate dosage, treatment intervals, management of extrapulmonary complications, and potential pediatric applications, warrant further exploration. These research avenues hold promise for enriching our understanding and refining the application of MSCs in confronting the multifaceted challenges posed by COVID-19.

Personalized Medicine in Severe Asthma: From Biomarkers to Biologics.

Severe asthma is a complex and heterogeneous clinical condition presented as chronic inflammation of the airways. Conventional treatments are mainly focused on symptom control; however, there has been a shift towards personalized medicine. Identification of different phenotypes driven by complex pathobiological mechanisms (endotypes), especially those driven by type-2 (T2) inflammation, has led to improved treatment outcomes. Combining biomarkers with T2-targeting monoclonal antibodies is crucial for developing personalized treatment strategies. Several biological agents, including anti-immunoglobulin E, anti-interleukin-5, and anti-thymic stromal lymphopoietin/interleukin-4, have been approved for the treatment of severe asthma. These biological therapies have demonstrated efficacy in reducing asthma exacerbations, lowering eosinophil count, improving lung function, diminishing oral corticosteroid use, and improving the quality of life in selected patients. Severe asthma management is undergoing a profound transformation with the introduction of ongoing and future biological therapies. The availability of novel treatment options has facilitated the adoption of phenotype/endotype-specific approaches and disappearance of generic interventions. The transition towards precision medicine plays a crucial role in meticulously addressing the individual traits of asthma pathobiology. An era of tailored strategies has emerged, allowing for the successful targeting of immune-inflammatory responses that underlie uncontrolled T2-high asthma. These personalized approaches hold great promise for improving the overall efficacy and outcomes in the management of severe asthma. This article comprehensively reviews currently available biological agents and biomarkers for treating severe asthma. With the expanding repertoire of therapeutic options, it is becoming increasingly crucial to comprehend the influencing factors, understand the pathogenesis, and track treatment progress in severe asthma.

Impact of Coronavirus Disease 2019 Pandemic on Pediatric Out-of-Hospital Cardiac Arrest in the Emergency Department.

Background: Out-of-hospital cardiac arrest (OHCA) in children is a critical condition with a poor prognosis. After the coronavirus disease 2019 (COVID-19) pandemic developed, the epidemiology and clinical characteristics of the pediatric emergency department (PED) visits have changed. This study aimed to analyze the impact of the COVID-19 pandemic on pediatric OHCA in the PED. Methods: From January 2018 to September 2021, we retrospectively collected data of children (18 years or younger) with a definite diagnosis of OHCA admitted to the PED. Patient data studied included demographics, pre-/in-hospital information, treatment modalities; and outcomes of interest included sustained return of spontaneous circulation (SROSC) and survival to hospital-discharge (STHD). These were analyzed and compared between the periods before and after the COVID-19 pandemic. Results: A total of 97 patients with OHCA (68 boys and 29 girls) sent to the PED were enrolled in our study. Sixty cases (61.9%) occurred in the pre-pandemic period and 37 during the pandemic. The most common age group was infants (40.2%) (p = 0.018). Asystole was the most predominant cardiac rhythm (72.2%, P = 0.048). Eighty patients (82.5%) were transferred by the emergency medical services, 62 (63.9%) gained SROSC, and 25 (25.8%) were STHD. During the COVID-19 pandemic, children with non-trauma OHCA had significantly shorter survival duration and prolonged EMS scene intervals (both p < 0.05). Conclusion: During the COVID-19 pandemic, children with OHCA had a significantly lower rate of SROSC and STHD than that in the pre-pandemic period. The COVID-19 pandemic has changed the nature of PED visits and has affected factors related to ROSC and STHD in pediatric OHCA.

Time-serial expression of toll-like receptor 4 signaling during polymicrobial sepsis in rats.

Sepsis caused by aggressive infection is a severe clinical problem with an increasing incidence worldwide. Toll-like receptors and their common adapter myeloid differentiation factor 88 (MyD88) can activate immune responses by recognizing a foreign microbe's product. This study aimed to identify the different time expression of TLR four signaling pathway in an experimental rodent model of polymicrobial sepsis. A randomized animal study was investigated in rats with septic peritonitis induced by cecal ligation and puncture (CLP). The expressions of MyD88-dependent pathway biomarkers, including MyD88, nuclear factor-κB (NF-κB), and serum tumor necrosis factor-α (TNF-α), were analyzed and compared to the sham controls at the different time points after CLP surgery. CLP-induced sepsis increased liver MyD88 mRNA expression and protein expression compared to the control groups at 2 h after surgery. The MyD88 mRNA and protein expressions in rats with CLP-induced sepsis marked increased at 4 and 6 h, and their NF-κB activities and serum TNF-α levels also increased at 4 h after CLP surgery (both p < .05). The different serial expression of MyD88-ependent pathway during sepsis may be used as biomarkers during sepsis. These results may provide further helpful information for using pro-inflammatory biomarkers of innate immunity such as MyD88 and TNF-α in clinical sepsis or related abdominal surgical emergency in the future.

Correlation Between Smoking Paradox and Heart Rhythm Outcomes in Patients With Coronary Artery Disease Receiving Percutaneous Coronary Intervention.

BACKGROUND: The effect of smoking on short-term outcomes among patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) is controversial. However, little is known about the impact of smoking on long-term outcomes in patients with stable coronary artery disease (CAD) who receive PCI. METHODS: A total of 2,044 patients with stable CAD undergoing PCI were evaluated. They were divided into two groups according to smoking status (current smokers vs. non-smokers). Baseline characteristics, exposed risk factors, angiographic findings, and interventional strategies were assessed to compare the long-term clinical outcomes between groups. Predictors for myocardial infarction (MI), all-cause death, cardiovascular (CV) death, and repeated PCI procedures were also analyzed. RESULTS: Compared with non-smokers, current smokers were younger and mostly male (both P < 0.01). They also had a lower prevalence of chronic kidney disease (CKD) and diabetes (both P < 0.01). Drugs including a P2Y12 receptor inhibitor of platelets (P2Y12 inhibitor), beta-blockers (BB), and statins were used more frequently in current smokers (P < 0.01, P < 0.01, P = 0.04, respectively). Freedom from all-cause death and CV death was lower in the non-smoker group (P < 0.001, P = 0.003, respectively). After adjustment, logistic regression revealed smoking was a major predictor for all-cause death and repeated PCI procedure [hazard ratio(HR): 1.71 and 1.46, respectively]. CONCLUSIONS: Smoker's paradox extends to long-term outcome in patients with stable CAD undergoing PCI, which is partially explained by differences in baseline characteristics. However, smoking strongly predicted all-cause mortality and repeated PCI procedures in patients with stable CAD undergoing PCI.

Central aortic pressure and long-term outcome in hypertensive patients undergoing percutaneous coronary intervention.

Elevated central pulse pressure (CPP) had a negative influence on long-term outcome in patients with hypertension (HT). However, little is known about the impact of central pulse pressure on long-term outcomes in hypertensive patients undergoing PCI. A total number of 1184 hypertensive patients who received PCI procedure were prospectively collected. They were divided into two groups according to the median of central pulse pressure. Baseline characteristics, risk factors, hemodynamic data including central systolic pressure (CSP), central diastolic pressure (CDP) and CPP were measured. Invasive strategies were also analyzed to compare the long term outcome between patients with reference CPP and patients with high CPP. We further analyzed the predictors for myocardial infarction (MI), mortality, repeated PCI procedure in hypertensive patients undergoing PCI. We found patients in the reference CPP group had a lower CSP and higher CDP compared with high CPP group (Both P < 0.001) and male preponderance (P < 0.001). Patients with diabetes and chronic kidney disease (CKD) tend to have a high CPP (both P < 0.001). Drugs including Angiotensin Converting Enzyme inhibitors (ACEI) and statin were used more frequently in patients with reference CPP group (P = 0.035 and P = 0.001, respectively). Freedom from all-cause mortality and cardiovascular(CV) mortality was lower in the patients with high CPP group (P = 0.001, P = 0.01, respectively).Logistic regression revealed that CPP is a major predictor for all-cause mortality and repeated PCI procedure [hazard ratio (HR): 2.46 and 1.41, respectively]. In hypertensive patients receiving PCI, elevated CPP had a negative impact on long-term mortality; CPP also strongly predicts all-cause mortality and repeated PCI procedures in hypertensive patients undergoing PCI.

Clinical spectrum of intra-abdominal abscesses in children admitted to the pediatric emergency department.

BACKGROUND: To analyze clinical spectrum of intra-abdominal abscesses in children and find helpful clinical parameters could aid physicians in earlier detection and differential diagnosis. METHODS: From 2004 to 2011, we retrospectively analyzed 66 pediatric patients, aged 18 years or younger with intra-abdominal abscesses. The data were obtained and studied: demographics, clinical presentations, etiologies, laboratory tests, microbiology, imaging studies, treatment modalities, complications and long-term outcomes. RESULTS: There were 66 patients (mean age, 9.27 ± 4.16 years) diagnosed as intra-abdominal abscesses. The two most common presented symptoms were fever and abdominal pain (90.9%; 78.8%, respectively). Most patients presented with leukocytosis (81.8%) and elevated C-reactive protein (CRP) levels (95.5%). In patients with abscesses in solid organs, urine white blood cell counts, nitrate and leukocyte esterase were all significant parameters (all P < 0.05), and urine pH and specific gravity were both lower than those in non-solid organs (P = 0.026; P = 0.043, respectively). Escherichia coli (E. coli) was the most common organism cultured from renal abscess. Streptococcus viridans was the most common organism cultured from liver abscess. Moreover, the two most predominant bacteria in periappendical and intraperitoneal abscesses were E. coli and Bacteroides fragilis. CONCLUSIONS: We suggest that primary physicians should keep this disease in mind when children present with predisposing risk factors, fever, abdominal pain, leukocytosis and elevated CRP level. Besides, we recommend the urinary analysis or ultrasonography (US) is valuable in patients with fever and abdominal pain.

Initial radiographic tracheal ratio in predicting clinical outcomes in croup in children.

Croup is the leading infectious disease resulting in pediatric upper airway obstruction. Our purpose is to analyze diverse features of neck radiographs could be seen as an objective tool to predict outcomes in patients with croup. One hundred and ninety-two patients were prospectively recruited in pediatric emergency department with diagnosis of croup. The initial Westley score (WS), presence of steeple sign, extent of narrowing, and narrowing ratio on soft tissue neck radiographs were determined before and after treatments. The extent of frontal narrowing, extent of lateral narrowing, frontal ratio (FR), and lateral ratio (LR) were investigated to predict clinical outcomes in patients with croup. The extent of frontal/lateral narrowing and LR had significant correlation with outpatient status. Almost 71% of patients with FR values below 0.23 stayed in the hospital longer, whereas nearly 98% of patients with FR vales above 0.65 could be discharged. About 85% of patients with LR below 0.45 hospitalized longer. The LR and FR were significantly correlated with the severity and admission rate in croup. The LR > 0.6 and FR > 0.65 may indicate low risk in patients with croup, whereas the FR < 0.23 or LR < 0.45 may indicate the need of stay in hospital for further treatment and monitor.

Influence of hypercholesterolemia and diabetes on long-term outcome in patients with stable coronary artery disease receiving percutaneous coronary intervention.

Coronary artery disease (CAD) is a life-threatening medical emergency which needs urgent medical attention. Percutaneous coronary intervention (PCI) is common and necessary for patients with CAD. The effect of hypercholesterolemia and diabetes on long-term outcomes in patients with stable CAD receiving PCI is unclear.In this study, patients with stable CAD who underwent PCI were prospectively divided into 4 groups according to the presence or absence of diabetes or hypercholesterolemia. Clinical characteristics, risk factors, medications, angiographic findings, and outcome predictors were analyzed and long-term outcomes compared between groups.Of the 1676 patients studied, those with hypercholesterolemia and diabetes had the highest all-cause mortality rate after PCI (P < .01); those with diabetes only had the highest cardiovascular (CV) mortality (P < .01). However, the 4 groups did not differ in rates of myocardial infarction (MI) or repeated PCI. In Kaplan-Meier survival analysis, patients with diabetes only had the highest rates of all-cause mortality and CV mortality (both P < .001). In the Cox proportional hazard model, patients with both hypercholesterolemia and diabetes had the highest risk of all-cause mortality (hazard ratio: 1.70), but groups did not differ in rates of MI, CV mortality, and repeated PCI.With or without hypercholesterolemia, diabetes adversely impacts long-term outcomes in patients receiving PCI. Diabetes mellitus seemed to be a more hazardous outcome predictor than hypercholesterolemia. Hypercholesterolemia and diabetes seemed to have an additive effect on all-cause mortality in patients after receiving PCI.

Clinical Survey and Predictors of Outcomes of Pediatric Out-of-Hospital Cardiac Arrest Admitted to the Emergency Department.

Pediatric out-of-hospital cardiac arrest (OHCA) is a rare event with severe sequelae. Although the survival to hospital-discharge (STHD) rate has improved from 2-6% to 17.6-40.2%, only 1-4% of OHCA survivors have a good neurological outcome. This study investigated the characteristics of case management before and after admittance to the emergency department (ED) associated with outcomes of pediatric OHCA in an ED. This was a retrospective study of data collected from our ED resuscitation room logbooks dating from 2005 to 2016. All records of children under 18 years old with OHCA were reviewed. Outcomes of interest included sustained return of spontaneous circulation (SROSC), STHD, and neurological outcomes. From the 12-year study period, 152 patients were included. Pediatric OHCA commonly affects males (55.3%, n = 84) and infants younger than 1 year of age (47.4%, n = 72) at home (76.3%, n = 116). Most triggers of pediatric OHCA were respiratory in nature (53.2%, n = 81). Sudden infant death syndrome (SIDS) (29.6%, n = 45), unknown medical causes (25%, n = 38), and trauma (10.5%, n = 16) were the main causes of pediatric OHCA. Sixty-two initial cardiac rhythms at the scene were obtained, most of which were asystole and pulseless electrical activity (PEA) (93.5%, n/all: 58/62). Upon ED arrival, cardiopulmonary resuscitation (CPR) was continued for 32.66 ± 20.71 min in the ED and 34.9% (n = 53) gained SROSC. Among them, 13.8% (n = 21) achieved STHD and 4.6% (n = 7) had a favorable neurological outcome. In multivariate analyses, fewer ED epinephrine doses (p < 0.05), witness of OHCA (p = 0.001), and shorter ED CPR duration (p = 0.007) were factors that increased the rate of SROSC at the ED. A longer emergency medical service (EMS) scene interval (p = 0.047) and shorter ED CPR interval (p = 0.047) improved STHD.

Hypertension and chronic kidney disease affect long-term outcomes in patients with stable coronary artery disease receiving percutaneous coronary intervention.

Percutaneous coronary intervention (PCI) is commonly used for patients with coronary artery disease (CAD). However, the effects of chronic kidney disease (CKD) and hypertension (HT) on long-term outcomes in patients with stable CAD receiving PCI are still unclear. A total of 1,676 patients treated with PCI were prospectively enrolled and divided into 4 groups according to the presence or absence of HT or CKD. General characteristics, clinical medications, risk factors, angiographic findings, and long-term outcomes were analyzed. Patients with CKD had the highest rate of all-cause and cardiovascular (CV) mortality (both P < 0.01). Patients with CKD alone had the lowest event-free rate of all-cause and CV deaths (both P < 0.001). Based on Cox proportional hazard model, patients with CKD alone had the highest risk of all-cause death (HR:2.86, 95% CI:1.73-4.75) and CV death (HR: 3.57,95% CI:2.01-6.33); while patients with both CKD and HT had the highest risk of repeat PCI (HR: 1.42, 95% CI:1.09-1.85).We found that in stable CAD patients after undergoing PCI, those with CKD alone had the highest long-term mortality. Comorbid CKD appears to increase risk in patient with HT, whereas comorbid HT doesn't seem to increase risk in patients with CKD.

Real-World Experience with Idarucizumab to Reverse Anticoagulant Effect in Dabigatran-Treated Patients: Report of 11 Cases from Taiwan.

BACKGROUND: This study aims to observe the effectiveness and safety of idarucizumab in dabigatran-treated patients with severe bleeding or requiring surgery in Taiwan. METHODS AND RESULTS: In Taiwan, 11 dabigatran-treated patients developed severe bleeding, fracture that needed surgery, and acute ischemic stroke requiring thrombolysis. These patients were treated with idarucizumab and obtained adequate hemostasis. Our experiences reconfirmed the efficacy and safety of idarucizumab in Asian patients. CONCLUSIONS: Idarucizumab improves safety in dabigatran-treated patients. Continued education about the availability and appropriate use of idarucizumab is necessary in Asia.

Chronic kidney disease and diabetes associated with long-term outcomes in patients receiving percutaneous coronary intervention.

BACKGROUND: The effect of diabetes mellitus (DM) and chronic kidney disease (CKD) on long-term outcomes in patients receiving percutaneous coronary intervention (PCI) is unclear. METHODS: A total of 1394 patients who underwent PCI were prospectively enrolled and divided into 4 groups according to the presence or absence of DM or CKD. Baseline characteristics, risk factors, medications, and angiographic findings were compared. Determinants of long-term outcomes in patients undergoing PCI were analyzed. RESULTS: Patients with DM and CKD had the highest all-cause mortality and cardiovascular mortality (both P < 0.01) but there were no differences existed in myocardial infarction (MI) or repeated PCI among the 4 groups (P = 0.19, P = 0.87, respectively). Patients with DM and CKD had the lowest even-free rate of all-cause mortality, cardiovascular mortality, MI, and repeated PCI (P < 0.001, P < 0.001, P < 0.001, and P = 0.002, respectively). In the Cox proportional hazard model, patients with both DM and CKD had the highest risk of all-cause mortality (HR: 3.25, 95% CI: 1.85-5.59), cardiovascular mortality (HR: 3.58, 95% CI: 1.97-6.49), MI (HR: 2.43, 95% CI: 1.23-4.08), and repeated PCI (HR: 1.79, 95% CI: 1.33-2.41). Patients with CKD alone had the second highest risk of all-cause mortality (HR: 2.04, 95% CI: 1.15-3.63), cardiovascular mortality (HR: 2.13, 95% CI: 1.13-4.01), and repeated PCI (HR: 1.47, 95% CI: 1.09-1.97). CONCLUSIONS: DM and CKD had additive effect on adverse long-term outcomes in patients receiving PCI; CKD was a more significant adverse predictor than DM.

Predictors of Extracorporeal Membrane Oxygenation Support for Children with Acute Myocarditis.

The clinical presentation of acute myocarditis in children may range from asymptomatic to sudden cardiac arrest. This study analyzed the clinical spectrum of acute myocarditis in children to identify factors that could aid primary care physicians to predict the need for extracorporeal membrane oxygenation (ECMO) earlier and consult the pediatric cardiologist promptly. Between October 2011 and September 2016, we retrospectively analyzed 60 patients aged 18 years or younger who were admitted to our pediatric emergency department with a definite diagnosis of acute myocarditis. Data on demographics, presentation, laboratory tests, electrocardiogram and echocardiography findings, treatment modalities, complications, and long-term outcomes were obtained. During the study period, 60 patients (32 male, 28 female; mean age, 8.8 ± 6.32 years) were diagnosed with acute myocarditis. Fever, cough, and chest pain were the most common symptoms (68.3%, 56.7%, and 53.3%, resp.). Arrhythmia and left ventricular ejection fraction (LVEF) < 60%, vomiting, weakness, and seizure were more common in the ECMO group than in the non-ECMO group, with statistical significance (P < 0.05). Female sex, vomiting, weakness, seizure, arrhythmia, and echocardiography showing LVEF < 60% may predict the need for ECMO. Initial serum troponin-I cutoff values greater than 14.21 ng/mL may also indicate the need for ECMO support for children with acute myocarditis.
