Assessment of the cardiac output at rest and during exercise stress using real-time cardiovascular magnetic resonance imaging in HFpEF-patients.

This methodological study aimed to validate the cardiac output (CO) measured by exercise-stress real-time phase-contrast cardiovascular magnetic resonance imaging (CMR) in patients with heart failure and preserved ejection fraction (HFpEF). 68 patients with dyspnea on exertion (NYHA ≥ II) and echocardiographic signs of diastolic dysfunction underwent rest and exercise stress right heart catheterization (RHC) and CMR within 24 h. Patients were diagnosed as overt HFpEF (pulmonary capillary wedge pressure (PCWP) ≥ 15mmHg at rest), masked HFpEF (PCWP ≥ 25mmHg during exercise stress but < 15mmHg at rest) and non-cardiac dyspnea.

Damages with High Consequences: Analysis of Perforations in Surgical Latex Operation Gloves from Orthopedic Surgeries.

Introduction: To prevent surgical site infections (SSIs) during operation, the use of sterile surgical latex gloves is common. The aim of this study was to examine the damage of the gloves in surgeries with different mechanical stress and the influence on the kind of damages. Gloves were collected during primary arthroplasty, revision arthroplasty (hip and knee), and arthroscopy (shoulder, hip, and knee).

Angiotensin II type 1 receptor expression in human coronary arteries with variable degrees of atherosclerosis.

Autopsy specimens of human coronary arteries were collected from 65 men and women ranging in age from 40-76 years of age. We made 209 coronary artery sections, which were graded in terms of severity of atherosclerosis by means of the Stary classification. Sections were stained using an antibody directed against the angiotensin II type 1 (AT1) receptor.

Pulmonary aspergilloma - clinical findings and surgical treatment.

The management of pulmonary aspergilloma is still a topic of discussion. Demonstrating several cases of pulmonary aspergilloma, their clinical course and their follow-up, we try to contribute some arguments for the preference of an early operation. Between 1992 and 1998, 18 patients underwent thoracotomy for treatment of pulmonary aspergilloma.

[An ultrasound hip screening program--middle term results of flexion-abduction orthosis therapy].

Introduction: Today the hip sonography is an established method to detect congenital hip maturation disturbances in the first days of life. Short-term follow-ups have showed that mature hip joints can be performed with an flexion-abduction bandage within a few months.

Methods: This prospective study reviews in a middle-term follow up 57 dysplastic hips at birth of 42 children after an average period of 7.
