Impact of COVID-19 on Healthcare Resource Utilisation Among Patients with Inflammatory Bowel Disease in the USA.

Background And Aims: The impact of the COVID-19 pandemic on patients with inflammatory bowel disease [IBD] is largely unknown. We characterised the impact of COVID-19 on IBD care by conducting an analysis of US health care claims data.

Methods: We obtained de-identified, open-source, health insurance claims data, from January 2019 to December 2020, from the Symphony Health Integrated Dataverse for US adults with IBD, and measured the rates per 1000 patients of five outcomes: colonoscopies; new biologic or small molecule treatment initiations or treatment switches; new biologic or small molecule treatment initiations or treatment switches in patients who had a colonoscopy within the previous 60 days; IBD-related surgeries; and telehealth consultations.

Cardiac fibroblasts support endothelial cell proliferation and sprout formation but not the development of multicellular sprouts in a fibrin gel co-culture model.

A primary impediment to cardiac tissue engineering lies in the inability to adequately vascularize the constructs to optimize survival upon implantation. During normal angiogenesis, endothelial cells (ECs) require a support cell to form mature patent lumens and it has been demonstrated that pericytes, vascular smooth muscle cells and mesenchymal stem cells (MSCs) are all able to support the formation of mature vessels. In the heart, cardiac fibroblasts (CFs) provide important electrical and mechanical functions, but to date have not been sufficiently studied for their role in angiogenesis.

[Effectiveness of heart tumor therapy in the cardiology department during 7 year follow-up].

Unlabelled: Neoplasms of the heart are rare. Usually asymptomatic on the early stage are diagnosed incidentally. Among primary heart neoplasms the most often benign tumors are diagnosed--mostly myxomas, whereas the majority of malignant heart tumors are sarcomas.

[Clinical significance of transesophageal and epiaortal echocardiography of ascending aorta in risk estimation of neurological complications in coronary artery by-pass patients].

Unlabelled: Advanced atherosclerotic changes in aortal wall are an important factor in taking decision to use minimal-invasive method of coronary artery by-pass grafting. There are some methods for diagnosing atherosclerotic changes in ascending aorta, i.e.

[Standard electrocardiography and Holter monitoring changes in acromegalic patients].

Unlabelled: Aberrations in circulation related to improper thyroid, parathyroid, adrenal and gonadal function were well researched and recognized. Our knowledge of relation between growth hormone and cardiovascular system is somewhat limited.

Aim Of The Study: Our attention was describe occurring in acromegaly complications of cardiovascular function detectable by standard 12-lead ECG and 24-hour Hotter monitoring.

Gene expression of kinin receptors B1 and B2 in PBMC from patients with cardiac syndrome X.

Introduction: Cardiac syndrome X (CSX) is defined by typical chest pain, ST segment depression on ECG and normal coronary angiography. Pathology of CSX may involve microvascular dysfunction related to inflammation and abnormal pain sensitivity. Kinins are labile peptides participating in vasodilation, inflammation and pain.

Left internal mammary artery improves 5-year survival in patients under 40 subjected to surgical revascularization.

Background: The population of young patients under 40 requiring coronary bypass surgery is characterized by an extremely and unusually rapid progression of coronary heart disease. The aim of the present study was to assess the clinical status and quality of life in these patients after surgery in relation to the type of conduit used to revascularize the left anterior descending artery (LAD).

Methods: One hundred seventeen patients under 40 (range, 30-40 years) underwent coronary artery bypass grafting (CABG) at our institution between 1991 and 1999.

[QT dispersion and characteristics of left ventricular hypertrophy in primary hypertension].

Unlabelled: The aim of the study was to evaluate the QT dispersion and the severity of arrhythmias in hypertensive patients according to the asymmetry of the left ventricular hypertrophy. The study group consisted of 47 hypertensive patients. In 24 of them the left ventricular hypertrophy was symmetrical (group I) and in 23--asymmetrical (group II).

[P-selectin and E-selectin in serum of patients with coronary artery disease].

Unlabelled: Evidence for the role of chronic inflammation in atherogenesis has been well documented. Selectins mediate the first step in leukocyte adhesion and may contribute to the pathogenesis of stable and unstable angina.

Methods: The study group consisted of 59 patients (pts) with coronary artery disease (CAD) documented coronarographically: 27 pts with stable exertional angina (group A), 32 pts with unstable angina (group B).

[Left and right ventricular function in acromegalic patients].

Recent studies have proved close relations between cardiovascular and endocrinic systems. This relation has been observed in acromegaly, the disease connected with unrestrained secretion of growth hormone. The aim of the study was to assess Holter monitoring and echocardiography of acromegalic patients.
