RESUMO

BACKGROUND: The American Heart Association recently introduced a new model for cardiovascular health (CVH) known as Life's Essential 8 (LE8). The impact of LE8 on hypertensive individuals is currently unclear. In our study, we investigated the correlation between comprehensive and individual CVH indicators as defined by LE8, and the mortality rates in hypertension patients. METHODS: We analyzed a total of 8,448 hypertensive individuals aged ≥ 20 years who participated in the National Health and Nutrition Examination Survey from 2007 to 2016. These participants were nonpregnant and noninstitutionalized. We identified their mortality by linking their data to the National Death Index until December 31, 2019. The overall cardiovascular health (CVH) was assessed using the LE8 score, which ranged from 0 to 100. Additionally, we evaluated the scores for each component of diet, physical activity, tobacco/nicotine exposure, sleep duration, body mass index, non-high-density lipoprotein cholesterol, blood glucose, and blood pressure. The CVH were categorized into low (0-49), moderate (50-79), and high (80-100) CVH. RESULTS: Over an average follow-up period of 7.41 years, 1,482 (17.54%) of the participants died, among which 472 deaths were attributed to CVD. When compared to adults with lower total CVH scores, those with elevated total CVH scores displayed a 37% reduced risk of mortality from all causes (adjusted hazard ratio [aHR] = 0.63, 95% confidence interval [CI] = 0.45-0.88). In relation to CVD-specific mortality, the corresponding aHRs for moderate and high total CVH scores were 0.76 (0.60-0.97) and 0.54 (0.31-0.94), respectively. Furthermore, after adjusting for potential confounders, it was observed that higher scores on the LE8 index were associated with a reduced risk of both all-cause mortality (aHR for every 10-score increase, 0.91; 95% CI = 0.86-0.96) and CVD-specific mortality (aHR for every 10-score increase, 0.82; 95% CI = 0.75-0.90). Notably, a linear dose-response relationship was observed in this association. Similar patterns were identified in the relationship between health behavior and both all-cause and CVD-specific mortality. CONCLUSIONS: Achieving a higher CVH score, as per the new LE8 guidelines, has been found to be associated with a reduced risk of mortality from all causes and specifically from CVD in patients with hypertension. Therefore, public health and healthcare initiatives that focus on promoting higher CVH scores could potentially yield significant benefits in terms of reducing mortality rates among individuals with hypertension.

RESUMO

R-loops are a common chromatin feature with essential functions in multiple cellular processes and diseases. However, little is known about the dynamic patterns of R-loops in a given organism. Here, using our recently developed genome-wide R-loop profiling method, we generated a comprehensive atlas quantifying the R-loop patterns of Arabidopsis (Arabidopsis thaliana) in 53 samples during development and during responses to environmental stimuli. The R-loop patterns were fairly stable in plants at the vegetative stage and in response to different light spectra and other environmental stimuli. Notably, the R-loops showed turnover during the plant life cycle, with patterns switching between generations. Importantly, R-loop dynamics was not strongly associated with RNA abundance, indicating that the mechanisms regulating R-loop formation and RNA accumulation are independent. We also observed enrichment of R-loops in transcription factor binding regions, suggesting that R-loops could function as potential cis-transcriptional regulators. This study provides an overview of R-loop dynamics in Arabidopsis during development and stress responses, highlights the unique dynamics of R-loops in the flowering plant Arabidopsis, and lays the groundwork for elucidating the functions of R-loops.

RESUMO

BACKGROUND: Proliferating cell nuclear antigen (PCNA) is one of the key factors for the DNA replication process and DNA damage repair. Most proteins interacting with PCNA have a common binding motif: PCNA interacting protein box (PIP box). However, some proteins with non-canonical PIP-box have also been reported to be the key factors that interacted with PCNA. RESULTS: Here we discovered the C terminal of a chromatin-remodeling factor CHR721 with non-canonical PIP-box was essential for interacting with OsPCNA in rice. Both OsPCNA and CHR721 were localized in the nuclei and function in response to DNA damages. CONCLUSIONS: Based on the results and previous work, we proposed a working model that CHR721 with non-canonical PIP-box interacted with OsPCNA and both of them probably participate in the DNA damage repair process.

RESUMO

Atrial fibrillation (AF) is highly prevalent in patients with mitral stenosis (MS), but the efficacy of left atrial appendage occlusion (LAAO) in these patients remains unclear.The aim of this study was to evaluate the efficacy and safety of LAAO in patients with MS complicated by AF at high risk of bleeding.We recruited patients from September 2015 to September 2018. We compared the 3-year outcomes of LAAO in 21 patients with AF complicated by MS and 42 sex- and age-matched patients with AF without MS.The MS group had more cases of peripheral arterial embolism (28.6% versus 2.4%, P = 0.004), more spontaneous echo contrast (47.6% versus 9.5%, P = 0.001), a larger LAA orifice diameter (P < 0.01), and a slower LAA flow (P < 0.05) than the Non-MS group. The mean size of the selected occluder device was bigger for patients with MS than for patients with Non-MS (29.2 ± 3.7 versus 26.9 ± 3.1 mm, P = 0.014). In the first 45 follow-up days, 2 (9.5%) patients with MS had device-related thrombi (DRT); one of them had transient ischemic attack 24 hours postoperatively. From 45 days to 6 months, one patient in each group had DRT. After 6 months, two patients in the Non-MS group still had residual leaks; one of them had a stroke, with a small DRT. The proportion of dual antiplatelet therapy was higher in the Non-MS group than in the MS group (33.3% versus 4.8%, P = 0.012), but this population had an increased bleeding risk.LAAO is relatively effective and safe for preventing embolic events in patients with MS complicated by AF, at high risk of bleeding.

RESUMO

OBJECTIVES: The risk of arrhythmia increases in diabetic patients. However, the effects of hyperglycemia and insulin therapy on the electrophysiological properties of human cardiomyocytes remain unclear. This study is to explore the effects of high glucose and insulin on the electrophysiological properties and arrhythmias of cardiomyocytes derived from human-induced pluripotent stem cells (hiPSC-CMs). METHODS: Immunofluorescent staining and flow cytometry were used to analyze the purity of hiPSC-CMs generated from human skin fibroblasts of a healthy donor. The hiPSC-CMs were divided into 3 group (treated with normal medium, high glucose and insulin for 4 days): a control group (NM group, containing 5 mmol/L glucose), a high glucose group (HG group, containing 15 mmol/L glucose), and a high glucose combined with insulin (HG+INS group, containing 15 mmol/L glucose+100 mg/L insulin). Electrophysiological changes of hiPSC-CMs were detected by microelectrode array (MEA) before or after treatment with glucose and insulin, including beating rate (BR), field potential duration (FPD) (similar to QT interval in ECG), FPDc (FPD corrected by BR), spike amplitude and conduction velocity (CV). Effects of sotalol on electrophysiological properties and arrhythmias of hiPSC-CMs were also evaluated. RESULTS: The expression of cardiac-specific marker of cardiac troponin T was high in the hiPSC-CMs. The purity of hiPSC-CMs was 99.06%. Compared with the NM group, BR was increased by (9.14±0.8)% in the HG group (P<0.01). After treatment with high glucose, FPD was prolonged from (460.4±9.0) ms to (587.6±23.7) ms in the HG group, while it was prolonged from (462.5±14.5) ms to (512.6±17.6) ms in the NM group. Compared with the NM group, FPD of hiPSC-CMs was prolonged by (16.8±1.4)% in the HG group (P<0.01). The FPDc of hiPSC-CMs was prolonged from (389.1±13.7) ms to (478.3±31.5) ms in the HG group, and that was prolonged from (387.7±21.6) ms to (422.6±32.9) ms in the NM group. Compared with the NM group, the FPDc of hiPSC-CMs was prolonged by (13.9±1.3)% in HG group (P<0.01). The spike amplitude and CV remained unchanged between the HG group and the NM group (P>0.05). Ten µmol/L of sotalol can induce significant arrhythmias from all wells in the HG group. After treatment with insulin and high glucose, compared with the HG group, BR was increased by (8.3±0.5)% in the HG+INS group (P<0.05). The FPD was prolonged from (463.4±9.7) ms to (532.6±12.8) ms in the HG+INS group, while it was prolonged from (460.4±9.0) ms to (587.6±23.7) ms in the HG group. Compared with the HG group, the FPD of hiPSC-CMs was shortened by (12.7±1.9)% in the HG+INS group (P<0.01). The FPDc of hiPSC-CMs was prolonged from (387.4±4.1) ms to (422.4±10.0) ms in the HG+INS group, and that was prolonged from (384.8±4.0) ms to (476.3±11.5) ms in HG group. Compared with the HG group, the FPDc of hiPSC-CMs was shortened by (14.7±1.1)% in HG group (P<0.01). After the insulin treatment, the spike amplitude of hiPSC-CMs was increased from (3.12±0.46) mV to (4.35±0.64) mV in the HG+INS group, while it was enhanced from (3.06±0.35) mV to (3.33±0.41) mV in the HG group. The spike amplitude of hiPSC-CMs was increased by (30.8±3.7)% in the HG+INS group compared with that in the HG group (P<0.05). The CV in the HG+INS group was increased from (0.23±0.08) mm/ms to (0.32±0.08) mm/ms after insulin treatment, which was increased from (0.21±0.04) mm/ms to (0.30±0.07) mm/ms in the HG group, but there was no significant difference in CV between the HG+INS group and the HG group (P>0.05). The induction experiment showed that 10 µmol/L of sotalol could prolong the FPDc of hiPSC-CMs by (78.9±11.6)% in the HG+INS group, but no arrhythmia was induced in each well. CONCLUSIONS: High glucose can induce FPD/FPDc of hiPSC-CMs prolongation and increase the risk of arrhythmia induced by drugs. Insulin can reduce the FPD/FPDc prolongation and the risk of induced arrhythmia by high glucose.These results are important to understand the electrophysiological changes of the myocardium in diabetic patients and the impact of insulin therapy on its electrophysiology. Further study on the mechanism may provide new ideas and methods for the treatment of acquired and even inherited long QT syndrome.

RESUMO

BACKGROUND: Postoperative pancreatic fistula (POPF) represents the most common complication following pancreaticoduodenectomy (PD). Predictive models are needed to select patients with a high risk of POPF. This study was aimed to establish an effective predictive nomogram for POPF following PD. METHODS: Consecutive patients who had undergone PD between January 2016 and May 2020 at a single institution were analysed retrospectively. A predictive nomogram was established based on a training cohort, and Lasso regression and multivariable logistic regression analysis were used to evaluate predictors. The predictive abilities of the predicting model were assessed for internal validation by the area under the receiver operating characteristic curve (AUC) and calibration plot using bootstrap resampling. The performance of the nomogram was compared with that of the currently used a-FRS model. RESULTS: A total of 459 patients were divided into a training cohort (n = 302) and a validation cohort (n = 157). No significant difference was observed between the two groups with respect to clinicopathological characteristics. The POPF rate was 16.56%. The risk factors of POPF POPF were albumin difference, drain amylase value on postoperative day 1, pancreas texture, and BMI, which were all selected into a nomogram. Nomogram application revealed good discrimination (AUC = 0.87, 95% CI: 0.81-0.94, P <  0.001) as well as calibration abilities in the validation cohort. The predictive value of the nomogram was better than that of the a-FRS model (AUC: 0.87 vs 0.62, P <  0.001). CONCLUSIONS: This predictive nomogram could be used to evaluate the individual risk of POPF in patients following PD, and albumin difference is a new, accessible predictor of POPF after PD. TRIAL REGISTRATION: This study was registered in the Chinese Clinical Trial Register ( ChiCTR2000034435 ).

RESUMO

A highly efficient and practical Pd(II)/Cu(OAc)2-catalyst system of Saegusa oxidation, which converts enol ethers to the corresponding enals with a number of diverse substrates at extremely low catalyst loadings (500 mol ppm) under ligand-free and aqueous conditions, is described. Its synthetic utility was demonstrated by large-scale applications of the catalyst system to important nature molecules. This work allows Saegusa oxidation to become a highly practical approach to preparing enals and also suggests new insight into the Pd(II)/Cu(II)-catalyst system for dehydrogenation of carbonyl compounds and decreasing Pd-catalyst loadings.

RESUMO

BACKGROUND: Postoperative complications after pancreatectomy are a challenging problem due to their high incidence and serious consequences. The majority of studies have focused on a specific complication, but data on predictors of overall postoperative complications (OPCs) are limited. METHODS: The data of patients who underwent pancreatectomy at a single institute between 2017 and 2019 were analyzed retrospectively. Univariate and multivariate logistic regression were used to investigate predictors of the outcomes of interest. The Clavien-Dindo classification and comprehensive complication index (CCI) were used to assess postoperative complications and the severity of postoperative complications. The relationship between predictors and the CCI was evaluated by linear regression. RESULTS: A total of 490 patients were divided into a training group (n = 339) and a validation group (n = 151). The rate of OPCs was 44.25%. Fluid transfusion and albumin difference (AD) were predictors of OPCs. AD showed a good discrimination (AUC = 0.70) and good calibration in the validation cohort. AD was associated with complications, including pancreatic fistula, intra-abdominal hemorrhage, intra-abdominal infection, delayed gastric emptying, and re-intervention, and was positively correlated with complication severity. Intraoperative blood loss and preoperative albumin were independent predictors of AD. CONCLUSIONS: AD, a variable that reflects dynamic physiological changes is a new and accessible predictor of OPCs following pancreatectomy.

RESUMO

In ophthalmologic or otolaryngologic studies, bilateral correlated data often arise when observations involving paired organs (e.g., eyes, ears) are measured from each subject. Based on Donner's model , in this paper, we focus on investigating the relationship between the disease probability and covariates (such as ages, weights, gender, and so on) via the logistic regression for the analysis of bilateral correlated data. We first propose a new minorization-maximization (MM) algorithm and a fast quadratic lower bound (QLB) algorithm to calculate the maximum likelihood estimates of the vector of regression coefficients, and then develop three large-sample tests (i.e., the likelihood ratio test, Wald test, and score test) to test if covariates have a significant impact on the disease probability. Simulation studies are conducted to evaluate the performance of the proposed fast QLB algorithm and three testing methods. A real ophthalmologic data set in Iran is used to illustrate the proposed methods.

RESUMO

KEY MESSAGE: CHR721 functions as a chromatin remodeler and interacts with a known single-stranded binding protein, OsRPA1a, to regulate both male and female reproductive development in rice. Reproductive development and fertility are important for seed production in rice. Here, we identified a sterile rice mutant, chr721, that exhibited defects in both male and female reproductive development. Approximately 5% of the observed defects in chr721, such as asynchronous dyad division, occurred during anaphase II of meiosis. During the mitotic stage, approximately 80% of uninucleate microspores failed to develop into tricellular pollen, leading to abnormal development. In addition, defects in megaspore development were detected after functional megaspore formation. CHR721, which encodes a nuclear protein belonging to the SNF2 subfamily SMARCAL1, was identified by map-based cloning. CHR721 was expressed in various tissues, especially in spikelets. CHR721 was found to interact with replication protein A (OsRPA1a), which is involved in DNA repair. The expressions of genes involved in DNA repair and cell-cycle checkpoints were consistently upregulated in chr721. Although numerous genes involved in male and female development have been identified, the mode of participation of chromatin-remodeling factors in reproductive development is still not well understood. Our results suggest that CHR721, a novel gene cloned from rice, plays a vital role in both male and female reproductive development.

RESUMO

It is well supported by the literature that the proliferation and migration of pulmonary arterial smooth muscle cells (PASMCs) are critical for the development of pulmonary arterial hypertension (PAH). Long intergenic noncoding RNA COX2 (lincRNA-COX2) is a regulator of inflammation and might be conducive to the progression of atherosclerosis, while its role in PAH is still unclear. This study was performed to explore the role and mechanism of lincRNA-COX2 in PASMCs proliferation and migration in an anaerobic environment. PASMCs were treated by hypoxia to construct PAH cell models. RT-PCR and western blot were recruited to evaluate the expression levels of lincRNA-COX2, miR-let-7a and STAT3. Their roles in proliferation and cell and migration of PASMCs were determined by the CCK-8 assay, wound-healing assay, and flow cytometry. In peripheral blood samples from PAH patients and hypoxic PASMCs, lincRNA-COX2 expression was enhanced. Silencing lincRNA-COX2 inhibited hypoxia-induced PASMCs proliferation by influencing the G2/M phase of the cell cycle. Meanwhile, lincRNA-COX2 regulated STAT3 through miR-let-7a and its effects on hypoxic PASMCs worked through miR-let-7a/STAT3 axis. To conclude, silencing lincRNA-COX2 attenuated the development of hypoxic PASMCs. LincRNA-COX2/miR-let-7a/STAT3 axis might be considered as a novel target to treat PAH.

RESUMO

PURPOSE: The level of albumin declines after surgery, and whether the difference between preoperative and postoperative albumin levels on postoperative day 1 has an effect on the development of postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP) is unclear. Our aim was to evaluate the effect of albumin difference on POPF. METHODS: A retrospective analysis of consecutive patients who had undergone DP between January 2016 and October 2018 at a single institution was conducted. Patient demographic data and perioperative data were analysed using univariate and multivariate models. Pancreatic fistula was defined by the 2016 International Study Group of Pancreatic Surgery criteria. All patients were followed for up to 90 days. RESULTS: A total of 211 consecutive patients were identified. The POPF rate was 15.64%, and no 90-day mortality was observed. Five predictors were independently associated with POPF: albumin difference (OR 6.60, 95% CI 2.36-18.45, P < 0.001), pancreatic texture (OR 4.15, 95% CI 1.62-10.63, P = 0.003), operative time (OR 3.13, 95% CI 1.19-8.24, P = 0.021), intraoperative fluid transfusion (OR 4.85, 95% CI 1.70-13.79, P = 0.003), and cardiovascular disease (OR 5.38, 95% CI 1.99-14.55, P = 0.001). CONCLUSIONS: Although DP can be performed with a low rate of mortality, POPF remains a common complication. Albumin difference is a new, accessible predictor for POPF following DP.

RESUMO

BACKGROUND: Multiple atrial septal defects (ASD) with an inferior sinus venosus defect (SVD) have always been considered to be contraindications for interventional therapy. On the basis of early experience using a patent ductus arteriosus (PDA) occluder for interventional treatment for inferior ASD, this study investigated the feasibility of transcatheter closure of multiple ASDs with an inferior SVD under the guidance of three-dimensional (3D) printed heart models. METHODS: Between August 2016 and February 2017, five patients who were diagnosed with multiple ASDs with an inferior SVD at the First Affiliated Hospital of Xi'an Jiaotong University underwent cardiac computed tomography (CT) scans and three-dimensional (3D) echocardiography to generate heart disease models by a 3D printing technique. The best occlusion program was determined through a simulated closure on the model. Percutaneous device closure of multiple ASDs with an inferior SVD was performed following the predetermined program, guided only by fluoroscopy. Follow-up included electrocardiography, transthoracic echocardiography, and transoesophageal echocardiography. RESULTS: Three-dimensional (3D) printed models for all five patients were produced successfully. Four (4) patients had a secundum ASD with an inferior sinus venosus ASD, and one patient had a patent foramen ovale (PFO) with an inferior sinus venosus ASD. All patients were successfully treated with interventional therapy. Inferior sinus venosus ASD was percutaneously closed using the PDA occluder, and the additional secundum ASD or PFO in each patient was percutaneously closed using an ASD or PFO occluder at the same time. There was no device embolisation, procedure-related death or pericardial tamponade. During the 1-year follow-up, a minor residual shunt was detected in one patient. CONCLUSION: The use of 3D printed ASD models provides a useful reference for transcatheter device closure of multiple ASD with an inferior SVD. This approach can provide a new treatment strategy for inferior sinus venosus ASD, which has been considered a contraindication for interventional therapy. However, long-term follow-up in a large number of patients is still warranted.

RESUMO

BACKGROUND: The latest 8th edition of the AJCC staging system emphasizes the importance of tumor size however, the clinical significance of the combination of tumor location with tumor size remains unknown. METHODS: We conducted this study to investigate the prognostic role of tumor location in T1 resectable pancreatic ductal adenocarcinoma (PDAC). Resectable PDAC patients from Surveillance, Epidemiology, and End Results (SEER) database (2004-2014) were selected for the propensity score matching analysis. We used matched cohort to analyze the relationship between clinicopathologic features and survival of patients. RESULT: Eight thousand, four hundred nine patients were included in the propensity score matching analysis and 4571 patients were selected for final analysis. In T1 patients, the patients with pancreatic head tumor had worse prognosis compared to the patients with body/tail tumors. Multivariate analysis result showed that pancreatic body/tail location was an independent indicator for better chances of survival in T1 PDAC patients (hazard ratio, 0.69; 95%CI, 0.52-0.93; P = 0.01). The modified staging system was more efficient than the AJCC 8th staging system. CONCLUSION: Modified staging system exhibited a good assessment of the survival rate. The tumor location is a good prognostic indicator for T1 resectable PDAC patients. Modification of T1 subgroup according to tumor location exhibited favorable survival prediction effects.

RESUMO

Numerous published studies have investigated the relationship between the CD14-260C>T (rs2569190) polymorphism and the risk of myocardial infarction (MI). However, the results are still conflicting and inconclusive. Potentially eligible published articles were searched in four databases including PubMed, Web of Science, EMBASE and Chinese Biomedical Database (CBM). The odds ratio (OR) with its 95% confidence interval (CI) was used to estimate the strength of the associations. Thirteen papers including 17 case-control studies were included, reporting a total of 6,443 MI patients and 6,315 controls. A significant increase in overall MI susceptibility was identified in the homozygote model. In the subgroup analysis, with respect to the type of MI, a significantly increasing acute MI susceptibility was found in the homozygote model. In the subgroup analysis for ethnicity, a significant increased susceptibility was found in Asian populations in allele, homozygote, recessive and dominant models. However, no significant association was found among Caucasian populations. In conclusion, there may be a moderate association between the CD14-260C>T polymorphism and acute MI susceptibility. This association may be different between ethnicities with the CD14-260C>T polymorphism being a risk factor for myocardial infarction in Asian populations.

RESUMO

Paradoxical peripheral embolism and submassive pulmonary embolism (PE), secondary to cancer-associated thrombosis, are yet to be reported in the literature. Here we describe a case presenting with an acute peripheral arterial embolism. Subsequent testing revealed a PE and an intrahepatic cholangiocarcinoma as the likely risk factors for thrombus, with arterial spread likely achieved through a patent foramen ovale. The patient's symptoms almost relieved upon catheter-directed thrombus fragmentation and aspiration, catheter-directed thrombolysis, and combined anticoagulation. Embolism and major bleeding did not occur during 6 months of follow-up under systemic anticoagulation with rivaroxaban. This case documents that catheter-directed thrombolysis and anticoagulation could be likely effective and safe in the treatment and prevention of recurrence of paradoxical embolism and PE secondary to cancer-associated thrombosis.

RESUMO

BACKGROUND: The role of progesterone receptor (PR) has been reported in a series of pancreatic cysts. However, the relationship between PR and prognosis of solid pseudopapillary neoplasm of the pancreas (SPNP) has not been elucidated so far. The aim of our study was to evaluate the prognostic value of PR in SPNP. METHODS: A total of 76 patients with SPNP treated in our institution from January 2012 to December 2017 were included. Demographic parameters, laboratory data, pathologic information and clinical outcomes were analyzed by the use of survival analysis. In addition, a pooled case series was performed to evaluate the results. RESULTS: The institutional data included 76 patients (17 male and 59 female) ranging from 8 to 90 years (median, 30 years) in age. Kaplan-Meier survival analysis confirmed negative PR result was significantly associated with poorer disease-free survival (DFS) and disease-specific survival (DSS) (both P < 0.001). In the pooled analysis, a total of 62 studies comprising 214 patients with SPNP were included. After multivariable cox analysis, negative PR result remained an independent prognostic factor for SPNP (DFS HR: 14.50, 95% CI: 1.98-106.05, P = 0.008; DSS HR: 9.15, 95% CI: 1.89-44.17, P = 0.006). CONCLUSION: Our results indicated the role of PR in predicting adverse outcome of patients with SPNP and negative PR result may serve as a potential prognostic factor.

RESUMO

BACKGROUND: To determine the relationship between maternal anxiety and cortisol values and birth weight at various stages of pregnancy. METHODS: Two hundred sixteen pregnant Chinese women were assessed for anxiety and depression and had measurement of morning fasting serum cortisol. Women were assessed either in the first (71), second (72) or third (73) trimester. Birth weights of all children were recorded. RESULTS: There were significant negative correlations between anxiety level and birth weight of - 0.507 (p < 0.01) and - 0.275 (p < 0.05) in trimesters 1and 2. In trimester 3 the negative relation between anxiety and birth weight of -.209 failed to reach significance (p = 0.070). There was no relation between depression and birth weight in any trimester (p > 0.5 for all). Maternal cortisol was significantly inversely related to birth weight in trimester 1 (r = - 0.322) and with borderline significance in trimester 2 (r = - 0.229). Anxiety score and maternal cortisol were significantly correlated in each trimester (r = 0.551, 0.650, 0.537). When both anxiety score and maternal cortisol were simultaneously included in multiple regression analyses only anxiety score remained significant. CONCLUSION: Whilst both maternal anxiety score and maternal cortisol are inversely related to birth weight the associations with anxiety score were more robust perhaps indicating the importance of mechanisms other than, or in addition to, maternal cortisol in mediating the effects of anxiety. The findings indicate the importance of measures to reduce maternal anxiety, particularly of a severe degree, at all stages of pregnancy. TRIAL REGISTRATION: The study was approved by the Ethics Committee of the 1st Affiliated Hospital of Xi'an Jiaotong University.

RESUMO

OBJECTIVES: To describe the multidisciplinary assessment of patent foramen ovale (PFO) with substantial right-to-left shunting (RLS) and medium-term follow-up after PFO closure for stroke or transient ischemic attack (TIA). BACKGROUND: PFO closure is a therapeutic option to prevent recurrent ischemic event in patients with cryptogenic stroke and TIA. The apparent lack of benefit seen in previous studies was in part due to the inclusion of patients with alternate mechanisms of stroke/TIA. However, the long-term follow-up results of RESPECT trial confirmed that PFO closure could reduce the recurrence rate of stroke compared to medical therapy. The obvious difference between RESPECT and the other studies is that RESPECT recruited more relevant patients with substantial RLS. METHODS: From May 2013 to October 2015, all subjects diagnosed as cryptogenic stroke or TIA with substantial RLS who underwent PFO closure at our institution were included. All patients underwent multidisciplinary assessment to exclude stroke/TIA with definite etiology. Baseline characteristics, clinical manifestations, procedural, and follow-up data were reviewed. RESULTS: A total of 219 consecutive patients with substantial RLS undergoing PFO closure were identified. There were no procedure-related deaths, strokes, or TIA. Mean follow-up was 2.0 ± 0.7 years. Early residual shunting was visible in 9 patients (4.1%); however, during follow-up, only 3 patients (1.4%) had residual RLS detected by contrast transthoracic echocardiography (cTTE). The annual risk of recurrent ischemic stroke or TIA was 0.457%. CONCLUSIONS: PFO closure can be performed safely and effectively in patients with cryptogenic stroke or TIA. In selected patients with substantial RLS, following appropriate multidisciplinary assessment, excellent results with low incidence of recurrent events may be achieved.
