Left atrial appendage (LAA), a blind pouch, accounts for more than 90% of the source of cardiac thrombus formation. Contrast retention (CR) in the LAA has been frequently observed during left atrial appendage occlusion (LAAO) procedures, especially in patients with stroke history. This study was designed to assess the relations between LAA contrast retention and thrombogenesis risk of the LAA in patients with non-valvular atrial fibrillation. A total of 132 consecutive patients who underwent LAAO were enrolled. The data collected from computed tomography (CT), transthoracic echocardiography (TTE), transesophageal echocardiography (TEE) and blood samples were analyzed. Univariate and multivariate logistic regression models were constructed to assess the association between CR, left atrial appendage thrombus (LAAT) and other factors. Contrast retention was observed in 33 patients, accounting for 25% of the population. Compared to the non-CR group, patients in the CR group had a larger left atrium anteroposterior diameter (49.64 ± 11.57 vs. 42.42 ± 7.04, P = 0.002), higher CHADS2 (3.88 ± 0.99 vs. 2.97 ± 1.35, P = 0.001) and CHA2DS2-VASc scores (5.79 ± 1.14 vs. 4.89 ± 1.56, P = 0.003), a higher rate of prior stroke (90.9% vs. 66.7%, P = 0.007), more LAA lobes (3.13 ± 1.18 vs. 2.64 ± 1.12, P = 0.038), and a higher prevalence of LAAT (63.6% vs. 13.1%, P  less then  0.001). After having adjusted the logistic model, only contrast retention, LAA cauliflower morphology and left ventricular ejection fraction (LVEF) were independently associated with LAAT. Patients with LAA contrast retention have a higher risk of left atrial appendage thrombosis. Contrast retention may be a cardiac factor strongly associated with cardiogenic stroke.

Gastric cancer is the third leading cause of cancer death and the fifth most common cancer worldwide. Screening is one of the most important ways to increase survival. The aim of this systematic review was to determinate barriers and facilitators for accessing gastric cancer screening.

In this systematic review, for identifying barriers and facilitators of gastric cancer screening, a comprehensive search was conducted in electronic databases such as PubMed, Web of Science, and Scopus in 2021. Combination keywords such as gastric cancer, screening, endoscopy, barriers, and facilitators were used for searching. Full text original studies in English language that are dealing with barriers and facilitators for accessing gastric cancer screening were included in this review.

A total 13 articles included in this review. Ten barriers and ten facilitators were evaluated. The most common reported barriers were lack of signs, fear of screening procedure, fear of screening outcome, cost of screening, and embarrassment. The most frequent facilitator was socio demographic factors such as age, education, and employment.

For promoting success in gastric cancer, screening programs, knowing barriers, and facilitators is necessary. No signs and symptoms of disease have been shown as the major barriers toward gastric cancer screening in most studies.

During development, physical forces deform the main rings into axially directed, antero-posterior tubes, while the sectors roll up to form cylinders that are perpendicular to the antero-posterior axis. As a consequence, the basic structure of the chicken embryo is a series of encased antero-posterior tubes (gut, neural tube, body envelope, amnion, chorion) decorated with smaller orifices (ear duct, eye stalk, nasal duct, gills, mouth) forming at right angles to the main body axis. We argue that the second-order divisions reflect the early pattern of cell cleavage, and that the transformation of radial and orthoradial lines into a body with sensory organs is a generic biophysical mechanism more general than the chicken embryo.

African Americans (AAs) and other racial/ethnic minority groups continue to be underrepresented in medical research and clinical trials. Failure to create more racially diverse research cohorts can exacerbate existing health disparities among these groups.

To investigate best practices and strategies for enhancing participation of AAs in medical research among attendees of a preconference Institute at a faith-based public health conference.

Qualitative study using semi-structured interviews.

A total of 21 out of 29 attendees (90% AA) of the Institute (72% response rate).

A culturally tailored preconference Institute was held at the 2017 Healthy Churches 2020 National Conference. The Institute was led by AA researchers focused on underrepresentation of AAs in medical research. Semi-structured interviews were conducted 1-year post-Institute (n=21) and were audio-recorded, transcribed verbatim, and reviewed using thematic analysis.

The majority of attendees reported that they were more likely to part in medical research were largely positive following their attendance at a conference-based Institute aimed to address the underrepresentation of AAs in medical research. Our culturally tailored approach to disseminating knowledge of the research process could extend to other national conferences prioritizing AAs and other racial/ethnic minority populations to improve research participation.

Frontline workers have been a bulwark in the fight against COVID-19, while being subject to major unexpected stressors. MLN2480 price These include conflicting news, evolving guidelines, perceived inadequate personal protective equipment, overflow of patients with rising death counts, absence of disaster training, and limitations in the implementation of social distancing. This study investigates the incidence and associated factors of depression, suicidal thoughts, and burnout among physicians during the COVID-19 pandemic.

In a cross-sectional survey-based study of resident, fellow, and attending physicians from a tertiary university hospital during the height of the COVID-19 pandemic in New York from April 24 to May 15, 2020, demographics and practice specialty, attending vs. resident/fellow status, call frequency, emotional exhaustion, depersonalization, and depression severity were examined.

Two hundred twenty-five subjects completed the survey (response rate of 16.3%), with rates of 6.2% depression, 6.6% suicidal ideation, and 19.
