Both the history of obesity and weight loss may change how menopause affects metabolic health. The purpose was to determine whether obesity and/or weight loss status alters energy balance (EB) and subsequent weight gain after the loss of ovarian function. Female lean and obese Wistar rats were randomized to 15% weight loss (WL) or ad libitum fed controls (CON). After the weight loss period, WL rats were kept in EB at the reduced weight for 8 weeks prior to ovariectomy (OVX). After OVX, all rats were allowed to eat ad libitum until weight plateaued...

Total daily energy expenditure (TEE) and physical activity level (PAL) are important for adequate nutritional management in athletes. The PAL of table tennis has been estimated to about 2.0: it is categorized as a moderate-activity sport (4.0 metabolic equivalents [METs]) in the Compendium of Physical Activities. However, modern table tennis makes high physiological demands. The aims of the present study were to examine (1) TEE and PAL of competitive table tennis players and (2) the physiological demands of various types of table tennis practice...

Systolic anterior motion (SAM) is defined as displacement of the distal portion of the anterior leaflet of the mitral valve toward the left ventricular outflow tract obstruction. SAM can occur in patients without hypertrophic cardiomyopathy (HOCM) and is a well-recognized cause for unexplained sudden hypotension in perioperative settings. We present a case of persistent orthostatic hypotension caused by SAM following left intrapericardial pneumonectomy and mediastinal lymph node dissection for squamous cell carcinoma of the lung invading intrapericardial portion of the inferior pulmonary vein...

We report a clinical case of a 40-year-old male with surgically corrected congenital heart disease (CHD) 10 years earlier: closure of ostium primum, mitral annuloplasty, and aortic valve and root surgery. The patient was admitted with acute heart failure. Transesophageal echocardiography (TEE) revealed a dysmorphic and severely incompetent aortic valve, a partial tear of the mitral valve cleft repair and annuloplasty ring dehiscence. A true left ventricular-to-right atrial shunt confirmed a direct Gerbode defect...

INTRODUCTION: Epiaortic ultrasound scanning (EAS) extended the use of ultrasound to the intraoperative diagnosis of aortic pathology. Surgical palpation of the ascending aorta underestimates the presence and severity of atherosclerotic plaques. Epiaortic ultrasound scanning has been used as an adjunct to transesophageal echocardiography (TEE) or as a primary direct diagnostic tool for imaging the ascending aorta as well as the aortic arch, which gained prominence as part of a multipronged intraoperative strategy to reduce atherosclerotic emboli...

AIMS: Mitral valve aneurysms (MVA) are most frequently associated with endocarditis. Echocardiography is the method of choice for diagnosis, and color flow imaging is an important, easy method to detect MVA ruptures. We aimed to study the clinical and echocardiographic findings and their relation to the mechanism of aneurysm formation. METHODS AND RESULTS: We reviewed clinical and echocardiographic records of 18 patients during a 17-year period, corresponding to 0...

This paper examines how people living in two socially contrasting areas of Stockton on Tees, North East England experience, explain, and understand the stark health inequalities in their town. Participants displayed opinions that fluctuated between a variety of converging and contrasting explanations. Three years of ethnographic observation in both areas (2014-2017) generated explanations which initially focused closely on behavioural and individualised factors, whilst 118 qualitative interviews subsequently revealed more nuanced justifications, which prioritised more structural, material and psychosocial influences...

INTRODUCTION: Tracheal intubation leading to injury of the airway is a rare complication of transesophageal echocardiography (TEE). Tracheal trauma is not a described complication of TEE, and safety literature for this procedure remains silent on the matter. We describe the case of a patient on systemic anticoagulation and antiplatelet therapy who underwent TEE and suffered massive hemoptysis requiring bronchial artery embolization (BAE). CASE PRESENTATION: An elderly patient was admitted to the hospital with recently diagnosed atrial fibrillation and shortness of breath...

AIMS: Trans-esophageal echocardiography (TEE) and MDCT currently serve as imaging modalities for left atrial appendage (LAA) occlusion pre-procedural planning. We assessed the feasibility of multi-detector CT (MDCT) based models to predict the correct size of device for LAA occlusion procedures. METHODS AND RESULTS: Patients planned for LAA occlusion underwent MDCT before implantation, which was used for creating and printing 3D LAA models. Three cardiologists evaluated the 3D models and predicted the correct size of the device by manual manipulation, these predictions were compared with the actual device implanted during the procedure...

Iatrogenic injury to the circumflex artery (Cx) due to its close proximity to the mitral annulus is a rare but dreadful complication that can occur during mitral valve repair. The aim of our study was to compare multiple measurements of the Cx datasets, obtained by real time three-dimensional transesophageal echocardiography (RT3D TEE) and corresponding measurements assessed in multi-planar three-dimensional images acquired by multidetector computed tomography (MDCT). Preoperative RT3D TEE and MDCT datasets of 25 patients who had previously undergone minimally invasive mitral valve surgery were retrospectively analyzed...

In the past decade, many studies have highlighted the role of metabotropic glutamate receptor subtype 5 (mGlu5) modulators in attenuating alcohol-related biological effects such as alcohol consumption, alcohol-seeking and relapse-like behaviors. Taken together, these findings suggest that pharmacological agents acting at mGlu5 could be promising tools in curbing inebriation. mGlu5s are present abundantly in brain regions known to be involved in emotion regulation, motivation and drug administration. On a cellular level, they are primarily located at the postsynaptic part of the neuron where the receptor is functionally linked to various downstream proteins that are involved in cell signaling and gene transcription that mediate the alcohol-induced neuroplasticity...

Newest 3D software allows measurements directly in the en-face-3D TEE mode. Aim of the study was to ascertain whether measurements performed in the en-face-3D TEE mode are comparable with conventional measurement methods based on 2D TEE and 3D using the multiple plane reconstruction mode with the Qlab(®) software. En-face-3D TEE is used more frequently in daily clinical routine during cardiac operations. So far measurements could only be done based on 2D images or with the use of multi planar reconstruction mode with additional software...
