AIMS: Heart failure with preserved (HFpEF) and mid-range ejection fraction (HFmrEF) are becoming the most prevalent forms of heart failure. Patients with HFpEF/HFmrEF in atrial fibrillation (AF) have poorer survival and quality of life, but the mechanism underpinning this is unknown. We sought to investigate the influence of AF on the haemodynamic profile of HFpEF/HFmrEF patients at rest and during exercise. METHODS AND RESULTS: We invasively measured central haemodynamics at rest and during symptom-limited supine bicycle exercise in HFpEF/HFmrEF patients, 35 in sinus rhythm and 20 in AF with matched left ventricular ejection fraction...

Aims: Concomitant surgical ablation of atrial fibrillation (AF) in patients undergoing mitral valve surgery (MVS) has almost become routine despite lack of convincing information about improved quality-of-life (QOL) and clinical benefit. Quality-of-life was therefore assessed after MVS with or without epicardial left atrial cryoablation. Methods and results: Sixty-five patients with permanent AF randomized to MVS with or without left atrial cryoablation, in the double-blinded multicentre SWEDMAF trial, replied to the Short Form 36 QOL survey at 6 and 12 months follow-up...

Maxillary sinus is more than any other paranasal sinuses amenable to various pathological conditions that may require the surgical treatment. The objective of the present work was to study the age-related and the individual specific anatomical features of the walls of the maxillary sinus and to develop the principles of sinus surgery based on the results of the anthropometric studies. We analyzed the cone-beam CT scans obtained from 586 patients at the age varying from 5 to 60 years who were allocated to six different groups...

The skull of the grey heron (Ardea cinerea) was examined with an emphasis on describing the orbital region. In the young (circa sixteen to seventeen days old) heron, the frontal bone (os frontale) and nasal bone (os nasale) comprised separate paired bones, connected by sutures (sutura interfrontalis, sutura internasalis and sutura frontonasalis plana). In adult animals, the relationship between these bones was different: the left and right frontal bone and the left and right nasal bone had grown together, and the frontal bone and nasal bone had fused into a common frontonasal bone (os frontonasale)...

Infection by Cryptosporidium baileyi was first confirmed in red grouse in northern England in 2010 and within three years spread to 48 per cent of moors. These form the last English stronghold for the rarer black grouse, and given the rapid spread of respiratory cryptosporidiosis among red grouse, concern has been expressed about possible infection. In 2010, the authors started screening black grouse for cryptosporidiosis in (1) dead birds taken for postmortem examination, (2) sample birds caught at night and (3) an observational study of birds attending leks...

Gallbladder (GB) adenomyomatosis (ADM) is a benign, acquired anomaly, characterized by hypertrophy of the mucosal epithelium that invaginates into the interstices of a thickened muscularis forming so-called Rokitansky-Aschoff sinuses. There are three forms of ADM: segmental, fundal and more rarely, diffuse. Etiology and pathogenesis are not well understood but chronic inflammation of the GB is a necessary precursor. Prevalence of ADM in cholecystectomy specimens is estimated between 1% and 9% with a balanced sex ratio; the incidence increases after the age of 50...

INTRODUCTION: Presence of chronic low grade inflammation has often been implicated in the etiology of atrial fibrillation (AF). Whether pre-existing inflammatory state promotes AF or initiation of AF activates inflammation is a dilemma among clinicians. This study investigates the role of high sensitive C reactive protein (hs-CRP) and interleukin 6 (IL-6) in AF with rheumatic mitral stenosis (Rh-MS) as markers of chronic inflammation. METHODS: This case control cohort included sixty five (n=65) Rh-MS patients having other valve lesions as trivial to mild...

This study analyzed the impact of sex, hemodynamic profile, and valve fusion pattern on aortopathy associated with bicuspid aortic valve (BAV). The National Heart Lung and Blood Institute-sponsored National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC) provided comprehensive information on a large population of well-characterized patients with BAV. Of 969 enrolled patients with BAV, 551 (57%, 77% male) had already undergone valvular and/or aortic surgery...

Impaired olfaction is associated with a volume decrease in the olfactory bulb as well as in the gray matter of cortical olfactory areas. On the other hand, restitution of an impaired olfaction results in a regain of volume in these regions. Studies investigating similar changes in the cerebral white matter are virtually not existent. The aim of this prospective study therefore was to investigate cerebral white matter using magnetic resonance diffusion tensor imaging (DTI). 31 patients (54±13years) with olfactory impairment (chronic rhinosinusitis) and planned functional endoscopic sinus surgery (FESS) were included...

BACKGROUND: Several grafting materials have been used in sinus augmentation procedures including autogenous bone, demineralized freeze-dried bone, hydroxyapatite, β-tricalcium phosphate, anorganic deproteinized bovine bone, and combination of these and others. Yet, the issue of the optimal graft material for sinus floor augmentation is controversial. PURPOSE: This prospective, randomized split-mouth study was undertaken to histomorphometrically compare a biphasic calcium phosphate (BCP) alloplastic bone substitute and a human bone mineral allograft (freeze-dried bone allograft, FDBA) in patients undergoing bilateral maxillary lateral sinus floor augmentation...

OBJECTIVES: Little is known about late detected anastomotic leakage after low anterior resection for rectal cancer, and the proportion of leakages that develops into a chronic presacral sinus. METHODS: In this collaborative snapshot research project, data from registered rectal cancer resections in the Dutch Surgical Colorectal Audit in 2011 were extended with additional treatment and long-term outcome data. Independent predictors for anastomotic leakage were determined using a binary logistic model...

Bacterial resistance is a growing phenomenon which led the scientific community to search for new therapeutic targets, such as biofilm. A bacterial biofilm is a surface-associated agglomerate of microorganisms embedded in a self-produced extracellular polymeric matrix made of polysaccharides, nucleic acids, and proteins. Scientific literature offers several reports on a biofilm's role in infections regarding various body districts. The presence of a bacterial biofilm is responsible for poor efficacy of antibiotic therapies along with bacterial infections in ear, nose, and throat (ENT) districts such as the oral cavity, ear, nasal cavities, and nasal sinuses...

A 36-year-old female was admitted to hospital exhibiting chest pain, dyspnea, and a heart murmur on the right upper sternal border, radiating to both carotid arteries. The blood pressure of the patient's right arm exceeded the pressure in the left by 25 mm Hg (Coanda effect). In spite of laboratory results that did not fall outside the expected range, the left ventricle was revealed to be hypertrophic following electrocardiography. Transthoracic echocardiography revealed a severe supravalvular aortic stenosis (SVAS) with a peak Doppler velocity of 6...
