4%), and combination of coronary artery bypass grafting and valve surgery in 103 (26.7%). Postoperative neurologic event rate was 2.6% (n = 10) which includes 5 (1.3%) transient ischemic attacks and 5 (1.3%) strokes (major n = 3, minor n = 2). The 30-day mortality rate was 3.9% (n = 15). Predictors of 30-day mortality included preoperative left heart insufficiency (odds ratio [OR] 5.44, 95% confidence interval [CI] 1.63-18.17, p = .006), and postoperative stroke (OR 197.11, 95%CI 18.28-2124.93, p < .001). No predictor for postoperative stroke and for composite endpoint was identified.
Considering that postoperative stroke rate and mortality was acceptably low, single-stage approach is an effective option in such selected high-risk patients.

This study aimed to report the real-world atrial fibrillation (AF) diagnostic yield of the implantable cardiac monitor (ICM) in patients with stroke or transient ischemic attack (TIA), and compare it to patients with an ICM for unexplained syncope.
We used patient data from device clinics across the United States of Americawith ICM remote monitoring via PaceMate™, implanted for stroke or TIA, and unexplained syncope. Patients with known AF or atrial flutter were excluded. The outcome was AF lasting ≥2 min, adjudicated by International Board of Heart Rhythm Examiners certifiedcardiac device specialists.
We included a total of 2469 patients, 51.1% with stroke or TIA (mean age 69.7 [SD 12.2] years, 41.1% female) and 48.9% with syncope (mean age 67.0 [SD 17.1] years, 59.4% female). The cumulative AF detection rate in patients with stroke or TIA was 5.5%, 8.9%, and 14.0% at 12, 24, and 36 months, respectively. The median episode duration was 73 (interquartile range 10-456) min, ranging from 2 min to 40.9 days, with 52.3%, 28.6%, and 4.4% of episodes lasting at least 1, 6, and 24 h, respectively. AF detection was increased by age (adjusted hazard ratio [for every 1-year increase] 1.024, 95% confidence interval 1.008-1.040; p = .003), but was not influenced by sex (p = .089). For comparison, the cumulative detection rate at 12, 24, and 36 months were, respectively, 2.4%, 5.2%, and 7.4% in patients with syncope.
Patients with stroke or TIA have a higher rate of AF detection. However, this real-world study shows significantly lower AF detection rates than what has been previously reported.

A variant of the psychological refractory period procedure was used with the first task, a speeded choice reaction to a tone and the second task, the unspeeded recall of letter triplets. Prior research had shown that recall accuracy dropped as the stimulus-onset asynchrony (SOA) decreased and task overlap increased. This could be due to interference with extracting perceptual information or to loss of the information while awaiting central resources. All four experiments showed evidence of interference, with the accuracy of recall for the first letter recalled relatively unaffected by SOA but with accuracy for later letters dropping as SOA decreased. Two of the experiments showed evidence for loss of second task information, with accuracy lower on trials with longer first task reaction times. The two other experiments showed loss of information when either the response complexity of Task 1 or the perceptual encoding difficulty was increased, increasing the processing time. The observed interference was attributed to slowed extraction of perceptual information. The observed loss was consistent with the encoded information being held in a fragile temporary store, susceptible to loss until consolidated into short-term memory. The evidence showed that the interference and the loss were independent processes.
Depressive symptoms, functional impairment, and decreased quality of life (QOL) are three important domains of major depressive disorder (MDD). However, the possible causal relationship between these factors has yet to be elucidated. Moreover, it is not known whether certain symptoms of MDD are more impairing than others. The network approach is a promising solution to these shortfalls.
The baseline data of a multicenter prospective project conducted in 11 governances of China were analyzed. In total, 1385 patients with MDD were included. Depressive symptoms, functioning disability, and QOL were evaluated by the 17-item Hamilton Depression Rating Scale (HAMD-17), the Sheehan Disability Scale (SDS), and the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF). The network was estimated through the graphical Least Absolute Shrinkage and Selection Operator (LASSO) technique in combination with the directed acyclic graph.
Three centrality metrics of the graphical LASSO showed tha.
This study aimed to elucidate the relationship between premature ventricular complexes (PVCs) and right ventricular (RV) dysfunction, and the effects of radiofrequency catheter ablation (RFCA) on RV function.
A total of 110 patients (age, 50.8 ± 14.4 years; 30 men) without structural heart disease who had undergone RFCA for RV outflow tract (RVOT) PVCs were retrospectively included. RV function was assessed using fractional area change (FAC) and global longitudinal strain (GLS) before and after RFCA. Clinical data were compared between the RV dysfunction (n = 63) and preserved RV function (n = 47) groups. The relationship between PVC burden and RV function was analyzed. Change in RV function before and after RFCA was compared between patients with successful and failed RFCA.
PVC burden was significantly higher in the RV dysfunction group than in the preserved RV function group (p < .001). L-α-Phosphatidylcholine price FAC and GLS were significantly worse in proportion to PVC burden (p < .001 and p < .001, respectively). The risk factor associated with RV dysfunction was PVC burden [odds ratio (95% confidence interval), 1.092 (1.052-1.134); p < .001]. Improvement in FAC (13.0 ± 8.7% and -2.5 ± 5.6%, respectively; p < .001) and GLS (-6.8 ± 5.7% and 2.1 ± 4.2%, respectively; p < .001) was significant in the patients with successful RFCA, compared to the patients in whom RFCA failed.
Frequent RVOT PVCs are associated with RV dysfunction. RV dysfunction is reversible by successful RFCA.

To review and evaluate the literature on the factors related to developing supportive relationships between women and midwives, including facilitators and barriers.
An integrative review.
The search used CINAHL, MEDLINE, Embase, EMcare, Maternity and Infant Care, PsycINFO, and Google Scholar from January 2009-June 2020. Two reviewers screened the eligible studies, and 2,399 records were identified. Quality was assessed with the mixed methods appraisal tool, and 14 articles were included.
The findings highlight that successful relationships require therapeutic communication, trust, respect, partnership, and shared decision-making. Supportive relationships improve women's satisfaction and birth outcomes, and continuity of care model is an enabling factor. Further research is required to understand supportive relationships in non-continuity of care models and when different cultural backgrounds exist.

To measure the frequency and spatial distribution of de novo mutations we divided three testes into 192 pieces each and used error-corrected deep-sequencing on each piece. We focused on PTPN11 (HGNC9644) Exon 3 that contains 30 different PTPN11 Noonan syndrome (NS) mutation sites. We found 14 of these variants formed clusters among the testes; one testis had 11 different variant clusters. The mutation frequencies of these different clusters were not correlated with their case-recurrence rates nor were case recurrence rates of PTPN11 variants correlated with their tyrosine phosphatase levels thereby confusing PTPN11's role in germline clonal expansion. Six of the PTPN11 exon 3 de novo variants associated with somatic mutation-induced sporadic cancers (but not NS) also formed testis clusters. Further, three of these six variants were observed among fetuses that underwent prenatal ultrasound screening for NS-like features. Mathematical modeling showed that germline selection can explain both the mutation clusters and the high incidence of NS (1/1000-1/2500).
The main aim of this study was to compare older patients with Alzheimer's disease (AD) to those with dementia with Lewy bodies (DLB) according to their dependency in daily living activities and comprehensive geriatric assessment parameters.
A total of 227 AD and 123 DLB patients underwent a geriatric assessment that included comorbidities, number of drugs used, falls, urinary incontinence, hand grip strength, Mini-Nutritional Assessment (MNA), Tinetti Performance Oriented Mobility Assessment Scale, Insomnia Severity Index (ISI), and Epworth Sleepiness Scale. Basic and instrumental activities of daily living were assessed by the Barthel Index and the Lawton scale, respectively.
The mean age of the participants was 83.4 years, and 73% were female. There were no statistically significant differences between AD and DLB patients in age, gender, cognitive function, or comorbidities except for coronary artery disease (P < 0.05). The number of falls, drugs used, and ISI and Epworth scores were higher in pati with DLB may be more difficult than older patients with AD.
Hybrid coronary revascularization (HCR) is a technique that merges coronary artery bypass grafting surgery and percutaneous coronary intervention (PCI) approaches for the treatment of multivessel coronary artery disease. The surgical component of the procedure is minimally invasive and can be done using robotic technology that avoids the need for sternotomy. Our objective is to study all patients who underwent robotic-assisted HCR (RHCR) to evaluate the feasibility and safety of the procedure during the establishment phase.
This study is a retrospective chart review conducted at King Faisal Specialist Hospital and Research Centre in Jeddah (KFSRC-J). The study focuses on patients who underwent RHCR between July 2018 to December 2020. The study was approved by the institutional review board #2020-103.
Robotic-assisted HCR was performed on 78 patients (mean age, 56 years (range, 43-72 years); 89.75% males) during the study phase. Left internal mammary artery grafting was used in all patients. There was no hospital mortality, and the mean hospital and intensive care unit(ICU) stay were 5.
