RESUMEN

BACKGROUND: Genetic susceptibility to the development of coronary artery disease (CAD) and myocardial infarction (MI) is well established. However, lack of replication, and difficulty in the identification of specific genes that underlie impressive linkage peaks remain challenges at the molecular level due to the heterogeneity of phenotype and their associated genotypes. We present two cases of first-degree family members of acute myocardial infarction (AMI) having similar clinical and angiographic features of obstructive coronary lesions at same anatomic locations. CASE PRESENTATION: The father presented with significant chest discomfort and loss of consciousness. The electrocardiogram (ECG) showed an acute anterior ST-segment-elevation myocardial infarction (STEMI). Coronary angiogram demonstrated a subtotal occlusion in the mid-left anterior descending (LAD) coronary artery. One week later, the son presented after an in-hospital cardiac arrest with pulseless electric activity preceded by significant chest pain and loss of consciousness. His ECG also showed an acute anterior STEMI. Catheterization revealed strikingly similar angiographic characteristics with his father: subtotal occlusion in the proximal to mid-LAD coronary artery. CONCLUSIONS: More considerations should be given to patients with similar phenotypic characterization in genetic studies of CAD/MI in the future.

RESUMEN

OBJECTIVE: To investigate the long-term clinical value of prostate 125I brachytherapy (BT) combined with maximal androgen blockade (MAB) in the treatment of metastatic prostate cancer (mPCa). METHODS: We retrospectively analyzed the clinical data on 173 cases of mPCa treated by MAB (n = 126) or BT+MAB (n = 47) from December 2011 to December 2016 and followed up for 6-76 (44.17 ± 19.73) months. We compared the PSA level, prostate volume, IPSS, progression-free survival, and the rates of 3- and 5-year overall survival between the two groups. RESULTS: After treatment, the minimum PSA level was significantly lower in the BT+MAB than in the MAB group ï¼»3.77 ± 4.14ï¼½ vs ï¼»5.96 ± 7.01ï¼½ ng/ml, P = 0.046) and the time to reach the minimum level was shorter in the former than in the latter (ï¼»5.19 ± 2.83ï¼½ vs ï¼»6.52 ± 3.34ï¼½ mo, P = 0.016). The prostate volume was markedly reduced in both of the groups at 1, 3 and 5 years after treatment as compared with the baseline, even more significantly in the BT+MAB than in the MAB group (P < 0.01), though with no statistically significant difference between the two groups before treatment (P = 0.307). The IPSS was remarkably decreased in both of the groups at 1 and 3 years (P < 0.01) but showed no significant difference at 5 years after treatment as compared with the baseline (P > 0.05) or between the two groups before and after treatment (P > 0.05). The progression-free survival was obviously longer in the BT+MAB than in the MAB group (ï¼»37.29 ± 15.73ï¼½ vs ï¼»29.41 ± 14.37ï¼½ mo, P = 0.011), and the rates of 3- and 5-year overall survival were higher in the former than in the latter (74.60% and 60.70% vs 62.60% and 51.50%, P = 0.227 and P = 0.356). Kaplan-Meier survival curves showed no statistically significant difference in the overall survival between the two groups (P = 0.105). CONCLUSIONS: Both MAB and BT+MAB are effective therapies for mPCa, but the latter can achieve a longer progression-free survival.

RESUMEN

OBJECTIVE: To study the clinical effect of psychological and behavioral intervention combined with biofeedback in the treatment of preschool children with attention deficit hyperactivity disorder (ADHD). METHODS: Sixty children each with inattentive, hyperactive/impulsive or combined type ADHD were enrolled. According to the intervention measure, they were randomly divided into 4 groups: control, psychological and behavioral intervention, biofeedback treatment and comprehensive treatment (psychological and behavioral intervention + biofeedback). Attention concentration time and impulse/hyperactivity and hyperactivity index scores of the Conners Parent Symptom Questionnaire (PSQ) were evaluated after 4 months of treatment. RESULTS: The attention concentration time increased in all types children with ADHD after psychological and behavioral intervention, biofeedback treatment or comprehensive treatment (P<0.05). In children with inattentive ADHD, hyperactive/impulsive ADHD or combined-type ADHD, biofeedback or comprehensive treatment reduced the impulse/hyperactivity index score (P<0.05). In children with inattentive or combined-type ADHD, psychological and behavioral intervention or comprehensive treatment reduced the hyperactivity index score (P<0.05). In children with hyperactive/impulsive ADHD, biofeedback treatment, psychological and behavioral intervention or comprehensive treatment reduced the hyperactivity index score (P<0.05). CONCLUSIONS: In children with ADHD, psychological and behavioral intervention combined with biofeedback treatment can improve the attention concentration and impulsive/hyperactive and hyperactive symptoms. The treatment strategies are slightly different for children with different types of ADHD.

RESUMEN

OBJECTIVE: To investigate the difference in the efficacy between clonidine transdermal patch and haloperidol tablets in the treatment of moderate to severe tic disorders in children. METHODS: A total of 134 children with moderate to severe tic disorders were randomly divided into clonidine group (n=70) and haloperidol group (n=64). The clonidine and haloperidol groups were treated with clonidine transdermal patch and haloperidol tablets respectively, and the treatment lasted for 8 weeks in both groups. The Yale Global Tic Severity Scale (YGTSS) was used to evaluate the conditions of the children before and after treatment, and the adverse events during the treatment were recorded. RESULTS: The haloperidol group had a significantly better treatment outcome than the clonidine group after one week of treatment (P<0.05); the treatment outcome showed no significant difference between the two groups after 3, 5, and 8 weeks of treatment (P>0.05). The clonidine group had significantly less reductions in the motor tics, vocal tics, and function impairment scores and total score of YGTSS than the haloperidol group after one week of treatment (P<0.05); there were no significant differences in YGTSS score reductions between the two groups after 3, 5, and 8 weeks of treatment (P>0.05). The clonidine group had a significantly lower overall incidence of adverse events than the haloperidol group (8% vs 37%; P<0.01). CONCLUSIONS: Clonidine transdermal patch and haloperidol are both effective in the treatment of moderate to severe tic disorders in children. The clonidine transdermal patch, despite slow action, has comparable efficacy and fewer adverse effects compared with haloperidol.

RESUMEN

PURPOSE: The purpose of this study was to evaluate the feasibility and safety of continuous glucose monitoring systems (CGMS) in ST segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary interventions (p-PCI) in coronary care units (CCU). METHODS: CGMS was performed for 3 days during CCU hospitalization for each of the subjects. The correlation between glucose values, recorded with CGMS, and finger-stick capillary glucose values was examined. The parameters and safety of CGMS were also investigated. RESULTS: Data from 219 subjects were included in the statistical analysis. Correlation analysis showed a strong positive correlation between interstitial glucose values recorded by CGMS and the corresponding capillary glucose values (P<0.001). The daytime mean blood glucose (MBG), the nighttime MBG and PT7.8 were the highest in the first day of CGMS compared with the second and third day. Furthermore, there were no indications of major hemorrhage or hematoma at the site of sensor insertion. Any adverse events were mild. CONCLUSIONS: CGMS glucose values are relatively accurate and reliable. CGMS were safe and can be used as a tool to detect trends in glucose levels and to predict upcoming glucose excursions in STEMI patients undergoing p-PCI.

RESUMEN

Left-sided congenital heart disease (CHD) encompasses a spectrum of malformations that range from bicuspid aortic valve to hypoplastic left heart syndrome. It contributes significantly to infant mortality and has serious implications in adult cardiology. Although left-sided CHD is known to be highly heritable, the underlying genetic determinants are largely unidentified. In this study, we sought to determine the impact of structural genomic variation on left-sided CHD and compared multiplex families (464 individuals with 174 affecteds (37.5%) in 59 multiplex families and 8 trios) to 1,582 well-phenotyped controls. 73 unique inherited or de novo CNVs in 54 individuals were identified in the left-sided CHD cohort. After stringent filtering, our gene inventory reveals 25 new candidates for LS-CHD pathogenesis, such as SMC1A, MFAP4, and CTHRC1, and overlaps with several known syndromic loci. Conservative estimation examining the overlap of the prioritized gene content with CNVs present only in affected individuals in our cohort implies a strong effect for unique CNVs in at least 10% of left-sided CHD cases. Enrichment testing of gene content in all identified CNVs showed a significant association with angiogenesis. In this first family-based CNV study of left-sided CHD, we found that both co-segregating and de novo events associate with disease in a complex fashion at structural genomic level. Often viewed as an anatomically circumscript disease, a subset of left-sided CHD may in fact reflect more general genetic perturbations of angiogenesis and/or vascular biology.

RESUMEN

It has been shown that impact damage to composite materials can be revealed by embedded Fiber Bragg Gratings (FBG) as a broadening and splitting of the latter's characteristic narrow peak reflected spectrum. The current work further subjected the impact damaged composite to cyclic loading and found that the FBG spectrum gradually submerged into a rise of background intensity as internal damages progressed. By skipping the impact, directing the impact to positions away from the FBG and examining the extracted fibers, we concluded that the above change is not a result of deterioration/damage of the sensor. It is caused solely by the damages initiated in the composite by the impact and aggravated by fatigue loading. Evolution of the grating spectrum may therefore be used to monitor qualitatively the development of the incurred damages.

RESUMEN

Purpose: Whether the diagnosis of non-alcoholic fatty liver disease or metabolic dysfunction-associated fatty disease has a different impact on liver transplant recipients with hepatocellular carcinoma is not yet clear. Methods: Data from a two-center retrospective cohort study were collected to compare and investigate the differences between non-alcoholic fatty liver disease and metabolic dysfunction-associated fatty liver disease in clinicopathologic parameters and prognosis among liver transplant recipients with hepatocellular carcinoma. Results: A total of 268 liver transplant recipients with hepatocellular carcinoma were included. The prevalence among pre- and post-transplant metabolic dysfunction-associated fatty liver disease was 10.82% and 30.22%, while for non-alcoholic fatty liver disease, it was 7.09% and 26.87%, respectively. The clinicopathological parameters were similar between the two pre-transplant groups. In contrast, the post-transplant group with metabolic dysfunction-associated fatty liver disease exhibited a higher prevalence of diabetes mellitus and a greater body mass index. However, the other parameters were similar between the two post-transplant groups (p > 0.05). Factors such as the largest tumor size > 4 cm, microvascular invasion, lack of tumor capsule, post-transplant metabolic dysfunction-associated fatty liver disease, and decreased post-transplant lymphocyte percentage were related to an increased risk of recurrence. Conclusion: In patients undergone liver transplantation for hepatocellular carcinoma, the diagnosis of metabolic dysfunction-associated fatty disease is more strongly associated with metabolic abnormalities than the diagnosis of non-alcoholic fatty liver disease and is an independent predictor of hepatocellular carcinoma recurrence.

RESUMEN

BACKGROUND: Metabolic dysfunction-associated fatty liver disease was proposed by international consensus to redefine the metabolic abnormal condition. However, its impact on liver transplant recipients with hepatitis B virus-related hepatocellular carcinoma has not been explored. METHODS: A two-center retrospective cohort study on liver transplant recipients with hepatitis B virus-related hepatocellular carcinoma was performed to analyze the impact of metabolic dysfunction-associated fatty liver disease on the clinicopathologic parameters and prognosis. RESULTS: There were 201 liver transplant recipients enrolled from two hospitals in our study. The pre- and post-transplant prevalences of metabolic dysfunction-associated fatty liver disease were 9.95% and 28.86%, respectively. The clinicopathological parameters revealed a similarity between patients with and without pre-transplant metabolic dysfunction-associated fatty liver disease. In contrast, the group with post-transplant metabolic dysfunction-associated fatty liver disease was linked with older age, a higher hepatitis recurrence rate and incidence of cardiovascular disease, usage of calcineurin inhibitors, a greater body mass index and waist circumference, lower albumin and high-density lipoprotein cholesterol levels, and poorer tumor-free survival and overall survival. The multivariate analysis showed the largest tumor size >4 cm (95% confidence intervals: 0.06~0.63, p = 0.006), microvascular invasion (95% confidence intervals: 1.61~14.92, p = 0.005), post-transplant metabolic dysfunction-associated fatty liver disease (95% confidence intervals: 1.40~10.60, p = 0.009), and calcineurin inhibitors-based regimen (95% confidence intervals: 0.33~0.96, p = 0.036) were the independent risk factors for recurrent hepatocellular carcinoma. CONCLUSIONS: Our study suggests that post-transplant metabolic dysfunction-associated fatty liver disease is more closely to metabolic abnormalities and that it can help identify liver transplant recipients at high risk of recurrent hepatocellular carcinoma.

RESUMEN

This study aimed to evaluate the efficacy and safety of remimazolam for intraoperative sedation during regional anesthesia. It was a phase II-multicenter, randomized, single-blind, parallel-group, active-controlled clinical trial (No. ChiCTR2100054956). From May 6, 2021 to July 4, 2021, patients were randomly enrolled from 17 hospitals in China. A total of 105 patients aged 18-65 years who underwent selective surgery under regional anesthesia were included. Patients received different sedatives with different dosages: 0.1 mg/kg remimazolam (HR), 0.05 mg/kg remimazolam (LR), or 1.0 mg/kg propofol (P) group, followed by a maintenance infusion. Main outcome measures included the efficacy of sedation measured by Modified Observer's Assessment of Alertness/Sedation Scale (MOAA/S) levels (1-4, 1-3, 2-3, 3, and 2-4) during the sedation procedure (the duration percentage) and incidence of adverse reactions. It showed that the duration percentage of MOAA/S levels 1-4 was 100.0 [8.1]% (median [interquartile range]), 89.9 [20.2]%, 100.0 [7.7]% in the HR, LR, and P groups, respectively. The percentage of patients in the HR, LR, and P groups who achieved MOAA/S levels 1-4 within 3 min after administration was 85.7%, 58.8%, and 82.9%, respectively. However, the time to recovery from anesthesia after withdrawal of sedatives (7.9 ± 5.7 min), incidence of anterograde amnesia (75%), and adverse effects were not statistically significant among the three groups. These findings suggest that a loading dose of remimazolam 0.1 mg/kg followed by a maintenance infusion of 0-3 mg/kg/h provides adequate sedation for patients under regional anesthesia without increasing adverse reactions.

RESUMEN

OBJECTIVE: Restrictive cardiomyopathy (RCM) is rare in children, and little is known about the molecular basis of RCM. The aim of this study was to investigate the clinical and myopathological characteristics and to detect mutations on cardiac sarcomere protein genes in three idiopathic pediatric RCMs. METHODS: Detailed clinical characteristics and familiar history were obtained in three idiopathic pediatric RCMs. One hundred healthy pediatric individuals were recruited as controls. Histological evaluation was performed with heart tissue retrieved at catheterization in case-1 and case-2. The entire coding sequences of four cardiac sarcomere protein genes, including cardiac troponin T (TNNT2), cardiac troponin I(TNNI3), ß-myosin heavy chain (MYH7), and α-actin (ACTC)were screened for mutations. Sequence variants were then tested in the family as well as in 100 healthy control DNAs. RESULTS: All three index cases were diagnosed as primary RCMs without family history, and their clinical conditions deteriorated rapidly. Case-1 was in combination with ventricular septal defect. Case-2 was in combination with mid- and inferoseptal hypertrophy. In case-1, myocardial biopsies displayed extensive an isomorphism and disarray of cardiomyocytes; electron microscopy showed large stacks of severely dysmorphic megamitochondria and focal Z-disc streaming. In case-2, endomyocardial biopsy revealed moderate myocyte hypertrophy with mild interstitial fibrosis; transmission electron microscopy showed misalignment of Z-bands and unequal Z-Z band distances. Genetic analysis identified two heterozygous missense mutations in TNNI3, with R204H in case-1 and R192H in case-3 respectively. A de novo heterozygous deletion in TNNT2 (p. Asn100_Glu101del) was identified in case-2. Sequence analysis shows that all three mutations are located in a position highly conserved across many species. The three mutations were negative for their parents and controls. CONCLUSION: The clinical conditions in all three index cases are deteriorated rapidly after diagnosed as primary RCM. Three heterozygous mutations including two in TNNI3 and one in TNNT2 gene are identified in the three RCMs respectively, which are considered as causative mutations. These findings provide new insights into the molecular etiology responsible for pediatric RCM.

RESUMEN

OBJECTIVE: To access the efficacy and safety of the double-ProGlide technique for the femoral vein access-site closure in cryoballoon ablation with uninterrupted oral anticoagulants (OAC), and its impact on the electrophysiology laboratory time as well as hospital stay after the procedure in this observational study. METHODS: Patients with atrial fibrillation undergoing cryoballoon ablation with uninterrupted OAC at Department of Cardiology, Beijing Anzhen Hospital, Capital Medical University, Beijing, China from May 2019 to May 2021 were enrolled in this study. From October 2020, double-ProGlide technique was consistently used for hemostasis (ProGlide group), and before that conventional manual compression was utilized (manual compression group). The occurrence of vascular and groin complications was accessed during the hospital stay and until the three-month follow-up. RESULTS: A total of 140 participants (69.30% of male, mean age: 59.21 ± 10.29 years) were evaluated, 70 participants being in each group. Immediate hemostasis was achieved in all the patients with ProGlide closure. No major vascular complications were found in the ProGlide group while two major vascular complications were occurred in the manual compression group. The incidence of any groin complication was obviously higher in subjects with manual compression than patients with ProGlide devices (15.71% vs. 2.86%, P = 0.009). In addition, compared with the manual compression group, the ProGlide group was associated with significantly shorter total time in the electrophysiology laboratory [112.0 (93.3-128.8) min vs. 123.5 (107.3-158.3) min, P = 0.006], time from sheath removal until venous site hemostasis [3.8 (3.4-4.2) min vs. 8.0 (7.6-8.5) min, P < 0.001], bed rest time [8.0 (7.6-8.0) h vs. 14.1 (12.0-17.6) h, P < 0.001] and hospital stay after the procedure [13.8 (12.5-17.8) h vs. 38.0 (21.5-41.0) h, P < 0.001]. CONCLUSIONS: Utilization of the double-ProGlide technique for hemostasis after cryoballoon ablation with uninterrupted OAC is feasible and safe, which has the clinical benefit in reducing the total electrophysiology laboratory time and the hospital stay length after the procedure.

RESUMEN

A novel double deletion in cardiac troponin T (cTnT) of two highly conserved amino acids (Asn-100 and Glu-101) was found in a restrictive cardiomyopathic (RCM) pediatric patient. Clinical evaluation revealed the presence of left atrial enlargement and marked left ventricle diastolic dysfunction. The explanted heart examined by electron microscopy revealed myofibrillar disarray and mild fibrosis. Pedigree analysis established that this mutation arose de novo. The patient tested negative for six other sarcomeric genes. The single and double recombinant cTnT mutants were generated, and their functional consequences were analyzed in porcine skinned cardiac muscle. In the adult Tn environment (cTnT3 + cardiac troponin I), the single cTnT3-ΔN100 and cTnT3-ΔE101 mutations had opposing effects on the Ca(2+) sensitivity of force development compared with WT, whereas the double deletion cTnT3-ΔN100/ΔE101 increased the Ca(2+) sensitivity + 0.19 pCa units. In addition, cTnT3-ΔN100/ΔE101 decreased the cooperativity of force development, suggesting alterations in intrafilament protein-protein interactions. In the fetal Tn environment, (cTnT1 + slow skeletal troponin I), the single (cTnT1-ΔN110) and double (cTnT1-ΔN110/ΔE111) deletions did not change the Ca(2+) sensitivity compared with control. To recreate the patient's heterozygous genotype, we performed a reconstituted ATPase activity assay. Thin filaments containing 50:50 cTnT3-ΔN100/ΔE101:cTnT3-WT also increased the myofilament Ca(2+) sensitivity compared with WT. Co-sedimentation of thin filament proteins indicated that no significant changes occurred in the binding of Tn containing the RCM cTnT mutation to actin-Tm. This report reveals the protective role of Tn fetal isoforms as they rescue the increased Ca(2+) sensitivity produced by a cTnT-RCM mutation and may account for the lack of lethality during gestation.

RESUMEN

AIMS: Although ventricular septal defects (VSD) are the most common congenital heart lesion, familial clustering has been described only in rare instances. The aim of this study was to identify genetic factors and chromosomal regions contributing to VSD. METHODS AND RESULTS: A unique, large kindred segregating various forms of septal pathologies-including VSD, ventricular septal aneurysms, and atrial septal defects (ASD)-was ascertained and characterized clinically and genetically. Eighteen family members in three generations could be studied, out of whom 10 are affected (2 ASD, 3 septal aneurysm, 4 VSD, and 1 tetralogy of Fallot). Parametric multipoint LOD scores reach significance on chromosome 10p15.3-10p15.2 (max. 3.29). The LOD score support interval is in a gene-poor region where deletions have been reported to associate with septal defects, but that is distinct from the DiGeorge syndrome 2 region on 10p. Multiple linkage analysis scenarios suggest that tetralogy of Fallot is a phenocopy and genetically distinct from the autosomal dominant form of septal pathologies observed in this family. CONCLUSION: This study maps a rare familial form of VSD/septal aneurysms to chromosome 10p15 and extends the spectrum of the genetic heterogeneity of septal pathologies. Fine mapping, haplotype construction, and resequencing will provide a unique opportunity to study the pathogenesis of septal defects and shed light on molecular mechanisms of septal development.

RESUMEN

OBJECTIVE: To explore the relationship between gene polymorphism of GABAA receptors and childhood autism by detecting rs140682, rs2081648 and rs140679 site of single nucleotide polymorphism (SNP) in GABAA receptors gene. METHODS: A total of 94 children with autism and 124 normal children were enrolled in a hospital from November 2010 to May 2011. Childhood autism rating scale (CARS) and autism behavior checklist (ABC) were used to evaluate or investigate the case group. After collecting venous blood and extracting the genome DNA, the allele and genotype of SNP rs140682, rs2081648 and rs140679 site in GABAA receptors gene were detected by PCR-RFLP. The allele and genotype of case group and control group were analyzed by χ(2) test, while the score of scales was analyzed by Spearman rank correlation analysis. RESULTS: The age of the case group was 5.12 ± 0.32, and it was 5.25 ± 0.27 in the control group (P < 0.05). In case group, the frequency of genotype CC, CT and TT of rs140682 site was 44, 41 and 9, while it was 48, 65, and 11 in control group (P > 0.05), respectively. The frequency of genotype AA, AG and GG of rs2081648 site was 8, 58 and 28 in case group, while it was 12, 49 and 63 in control group (P < 0.05), respectively. In case group, the frequency of genotype CC, CT and TT of rs140679 site was 15, 36 and 43, while it was 18, 59 and 47 in control group (P > 0.05), respectively. It was revealed by Spearman rank correlation analysis that of rs2081648 site, there was a positive correlation between genotype AG and sensation factor (S), social intercourse factor (R), and language factor (L) of autism behavior checklist (ABC) (r values were 0.149, 0.165 and 0.155, all P values < 0.05). A negative correlation between genotype GG and S, R, L and self-help factor (V) was proved (r values were -0.140, -0.173, -0.158 and -0.135, all P values < 0.05). There was a positive correlation between allele A and R and L factors (r values were 0.153 and 0.137, all P values < 0.05), while a negative correlation between allele G and R and L factors (r values were -0.153 and -0.137, all P values < 0.05). In case group, 42 children were diagnosed with mild-to-moderate autism, while 52 children were severe autism. There was no statistically significant correlation between allele or genotype of SNP rs140682 and rs140679 site and the degree of autism (P > 0.05). There was a positive correlation between allele A and genotype AG and the degree of autism (r values were 0.147 and 0.616, all P values < 0.05), while a negative correlation between allele G and genotype GG and the degree of autism (r values were -0.159 and -0.616, all P values < 0.05). CONCLUSION: The SNP rs2081648 site which located in GABAA receptors gene may be related to autism. No evidence for significant association between rs140682 and rs140679 site and autism was found.

RESUMEN

BACKGROUND: Patent foramen ovale (PFO) is the most common congenital heart disease and is associated with several diseases, including stroke and migraine. PFO diagnosis involves transoesophageal echocardiography, transthoracic echocardiography, and transcranial Doppler. Recent studies have shown that intracardiac echocardiography (ICE) can be used to diagnose and guide percutaneous transcatheter closure. CASE SUMMARY: A 70-year-old male presented with paroxysmal dizziness and limb weakness for the past 3 mo. Magnetic resonance imaging revealed a history of stroke, and a bubble test revealed the presence of PFO. The patient was then transferred to our hospital for PFO closure. Under ICE guidance, the separation of the septum primum and septum secundum was unclear; we then used a Swartz catheter to confirm PFO by applying physical pressure on the right part of the atrial septum without using any contrast. The ICE continuously and clearly guided the procedure. CONCLUSION: ICE can guide PFO closure in patients with a history of stroke. When PFO is not evident under ICE, a Swartz catheter can be used.

RESUMEN

BACKGROUND: The relationship between preprocedural C-reactive protein (CRP) levels and the incidence of contrast-induced acute kidney injury (CI-AKI) is unknown. METHODS: Documents of 7,310 consecutive patients undergoing percutaneous coronary intervention (PCI) were screened. Patients with acute myocardial infarction, cardiogenic shock, concomitant inflammatory conditions or undergoing CABG within 48 h were excluded due to potential confounding effects. RESULTS: A total of 4,522 patients were valid for analysis. The median follow-up was 26 months (interquartile range 20-33 months). According to preprocedural CRP values, patients were divided into 3 groups: group 1: CRP <1.0 mg/l (n = 1,523); group 2: 1.0 mg/l ≤ CRP ≤ 3.0 mg/l (n = 1,626); group 3: CRP >3.0 mg/l (n = 1,373). Patients with higher preprocedural CRP levels were associated with a significantly increased rate of CI-AKI (10.6 vs. 14.9 vs. 23.5%, p < 0.0001). After adjustment for baseline covariates, CRP level was still an independent predictor for the incidence of CI-AKI, either as a continuous variable or a categorical variable. Patients with higher CRP values had a significantly higher rate of all-cause mortality and myocardial infarction during follow-up. CONCLUSION: Elevated preprocedural CRP is associated with an increased risk for CI-AKI in patients undergoing PCI. Preprocedural risk stratification with CRP as an adjunct to established clinical risk factors might be useful.

RESUMEN

The imbalance between the anabolism and catabolism of the extracellular matrix (ECM) is of great importance to osteoarthritis (OA) development. Aberrant inflammatory responses and hypertrophic changes of chondrocytes are the main contributors to these metabolic disorders. In the present study, we found that Oroxylin A (ORA), a flavonoid compound derived from Oroxylum indicum, maintained ECM hemostasis of chondrocytes by Interleukin-1ß (IL-1ß) stimulation. Besides, it was demonstrated that IL-1ß induced over-production of inflammatory mediators was attenuated by ORA treatment. Moreover, ORA could rescue IL-1ß mediated hypertrophic alterations of chondrocytes. Mechanistically, ORA's protective effects were found to be associated with both NF-κB and Wnt/ß-catenin signaling inhibition. Meanwhile, molecular docking analysis revealed that ORA could strongly bind to the inhibitor kappa B kinaseß (IKKß) and dishevelled, Dsh Homolog 2 (Dvl2), the upstream molecules of the NF-κB axis and ß-catenin axis, respectively. In addition, ORA driven chondroprotective effects were also affirmed in a surgically induced OA mouse model. Taken together, the current study suggested that ORA might be a promising therapeutic option for the treatment of OA.

RESUMEN

PURPOSE: Ductal carcinoma in situ with microinvasion (DCISM) can be challenging to balance the risks of overtreatment versus undertreatment. We aim to identify prognostic factors in patients with DCISM and construct a nomogram to predict breast cancer-specific survival (BCSS). MATERIALS AND METHODS: A retrospective cohort study of women diagnosed with DCISM from 1988 to 2015 who were identified in the Surveillance, Epidemiology and End Results database. Clinical variables and tumor characteristics were evaluated, and Cox proportional-hazards regression was performed. A nomogram was constructed from the multivariate logistic regression to combine all the prognostic factors to predict the prognosis of DCISM patients at 5 years, 10 years, and 15 years. RESULTS: We identified 5438 total eligible breast cancer patients with a median and max survival time of 78 and 227 months, respectively. Here, patients with poorer survival outcomes were those diagnosed between 1988 and 2001, African-American race, under 40 years of age, higher tumor N stage, progesterone receptor-negative tumor, and received no surgery. The nomogram was constructed by the seven variables and passed the calibration and validation steps. The area under the receiver operating characteristic (ROC) curve (AUC) of both the training set and the validating set (5-year AUC: 0.77 and 0.88, 10-year AUC: 0.75 and 0.73, 15-year AUC: 0.72 and 0.65). Receiving chemotherapy was associated with a better BCSS (hazard ratio, HR=0.45, 95% confidence interval, 95% CI = 0.23-0.89), especially in patients with estrogen receptor (ER) negative, progesterone receptor (PR) negative (HR = 0.35, 95% CI = 0.13-0.97) and ER+PR-/ER-PR+ DCISM (HR = 0.07, 95% CI = 0.01-0.59). CONCLUSION: Our current study is the first to construct nomograms of patients with DCISM which could help physicians identify breast cancer patients that more likely to benefit from more intensive treatment and follow-up. Chemotherapy might benefit patients with ER-PR- and ER+PR-/ER-PR+ DCISM.

RESUMEN

BACKGROUND: The Trial to Assess Chelation Therapy study found that edetate disodium (disodium ethylenediaminetetraacetic acid) chelation therapy significantly reduced the incidence of cardiac events in stable post-myocardial infarction patients, and a body of epidemiological data has shown that accumulation of biologically active metals, such as lead and cadmium, is an important risk factor for cardiovascular disease. However, limited studies have focused on the relationship between angiographically diagnosed coronary artery disease (CAD) and lead exposure. This study compared blood lead level (BLL) in Chinese patients with and without CAD. METHODS: In this prospective, observational study, 450 consecutive patients admitted to Beijing Anzhen Hospital with suspected CAD from November 1, 2018, to January 30, 2019, were enrolled. All patients underwent coronary angiography, and an experienced heart team calculated the SYNTAX scores (SXscore) for all available coronary angiograms. BLLs were determined with atomic absorption spectrophotometry and compared between patients with angiographically diagnosed CAD and those without CAD. RESULTS: In total, 343 (76%) patients had CAD, of whom 42% had low (0-22), 22% had intermediate (23-32), and 36% had high (≥ 33) SXscore. BLLs were 36.8 ± 16.95 µg/L in patients with CAD and 31.2 ± 15.75 µg/L in those without CAD (P = 0.003). When BLLs were categorized into three groups (low, middle, high), CAD prevalence increased with increasing BLLs (P < 0.05). In the multivariate regression model, BLLs were associated with CAD (odds ratio (OR): 1.023, 95% confidence interval (CI): 1.008-1.039; P = 0.0017). OR in the high versus low BLL group was 2.36 (95% CI: 1.29-4.42,P = 0.003). Furthermore, BLLs were independently associated with intermediate and high SXscore (adjusted OR: 1.050, 95% CI: 1.036-1.066; P < 0.0001). CONCLUSION: BLLs were significantly associated with angiographically diagnosed CAD. Furthermore, BLLs showed excellent predictive value for SXscore, especially for complex coronary artery lesions.
