Influence of prosthesis-patient mismatch on left ventricular remodelling in severe aortic insufficiency.

Objective: The present study evaluates the impact of prosthesis-patient mismatch (PPM) on left ventricular remodelling following aortic valve replacement (AVR) for severe aortic insufficiency. Methods: In this study, 230 patients undergoing aortic valve surgery were divided into two groups depending on whether or not they exhibited PPM. Postoperative left ventricular (LV) dimensions and function w

Phagocytosis of apoptotic cells by macrophages in anti-neutrophil cytoplasmic antibody-associated systemic vasculitis.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of autoimmune diseases, including granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). It is not known why ANCA develop, but it has been shown that they participate in pathogenesis by activating polymorphonuclear neutrophils (PMNs). In this study we hypothesize that dysregulation of phagocytosi

Alternative food systems and the citizen-consumer

Ethically informed and committed consumers are crucial to the functioning of many alternative food systems. These consumers are poorly understood, though, and their common description as informed and democratically minded finds little resemblance to the real world. Few individuals fit the ideal of the concept of the so-called citizen-consumer. This commentary therefore argues that both researchers

Anisakis simplex-sensitized patients: should fish be excluded from their diet?

BACKGROUND: Anisakis simplex (A.s.) allergy is an emerging disease. The third-stage larvae of this nematode are a source of hidden allergens in fish. There are no clear guidelines concerning dietary restrictions for patients with serum-specific IgE to this parasite. OBJECTIVE: To follow up the clinical data and immunological parameters of patients sensitized to A.s. during 6 to 23 months. METHODS:

Reducing Unnecessary Biopsy During Prostate Cancer Screening Using a Four-Kallikrein Panel: An Independent Replication.

PURPOSE: We previously reported that a panel of four kallikrein forms in blood-total, free, and intact prostate-specific antigen (PSA) and kallikrein-related peptidase 2 (hK2)-can reduce unnecessary biopsy in previously unscreened men with elevated total PSA. We aimed to replicate our findings in a large, independent, representative, population-based cohort. PATIENTS AND METHODS: The study cohort

Lipomatous hypertrophy of the interatrial septum in a patient with carcinoma: a case report of the importanceof multi-modality imaging.

Introduction: Lipomatous hypertrophy of the interatrial cardiac septum is a benign disorder. In rare cases, the disorder can cause obstruction of atrial inflow, causing symptoms of heart failure, or cardiac arrhythmias resulting from the involvement of the atrial wall and atrioventricular conduction pathways. Case presentation: We present a case of a Caucasian 66-year-old man with urothelial carci

Serotonergic and dopaminergic mechanisms in graft-induced dyskinesia in a rat model of Parkinson's disease.

Dyskinesia seen in the off-state, referred as graft-induced dyskinesia (GID), has emerged as a serious complication induced by dopamine (DA) cell transplantation in parkinsonian patients. Although the mechanism underlying the appearance of GID is unknown, in a recent clinical study the partial 5-HT(1A) agonist buspirone was found to markedly reduce GID in three grafted patients, who showed signifi

Health-promoting and health-damaging neighbourhood resources and coronary heart disease: a follow-up study of 2 165 000 people.

Background It has been hypothesised that the presence of health-damaging factors and lack of health-promoting factors lie in the causal pathway between neighbourhood deprivation and coronary heart disease (CHD). This study is the first to examine the associations between individual-level CHD risk and neighbourhood availability of fast-food restaurants, bars/pubs, physical activity facilities and h

Expression of somatostatin receptor subtypes 2 and 4 in human benign prostatic hyperplasia and prostatic cancer.

BACKGROUND: The presence of receptor subtypes for the inhibitory peptide somatostatin in prostatic tissue has been a controversial issue with conflicting reports. To elucidate whether prostatic epithelial cells express mRNA for somatostatin receptor (SSTR) subtype 2 and 4, we have investigated the localization of SSTR2 and SSTR4 transcripts in prostatic tissues by in situ hybridization. METHODS: N

On force control for assembly and deburring of castings

Traditional industrial robots have problems interacting with an uncalibrated, ill-defined environment where part geometry and position may vary. Active force control technology has therefore been suggested as a solution to add the extra sensory dimension needed to handle manufacturing tasks like assembly and deburring. The technology is proposed to give increased flexibility compared to other solu

The MBOAT7-TMC4 Variant rs641738 Increases Risk of Nonalcoholic Fatty Liver Disease in Individuals of European Descent.

Nonalcoholic fatty liver disease (NAFLD) is a leading cause of liver damage and is characterized by steatosis. Genetic factors increase risk for progressive NAFLD. A genome-wide association study showed that the rs641738 C>T variant in the locus that contains the membrane bound O-acyltransferase domain-containing 7 gene (MBOAT7, also called LPIAT1) and transmembrane channel-like 4 gene (TMC4) incr

Enrollment experiences in a pediatric longitudinal observational study: The Environmental Determinants of Diabetes in the Young (TEDDY) study.

OBJECTIVE: Our objective was to identify characteristics of infants and their families who were enrolled, refused to enroll, or were excluded from The Environmental Determinants of Diabetes in the Young (TEDDY) study. METHOD: 16,435 infants screened at birth and identified as at increased genetic risk for type 1 diabetes (T1DM) were placed into one of three categories: enrolled, excluded, or refus

Zoom-in array comparative genomic hybridization (aCGH) to detect germline rearrangements in cancer susceptibility genes.

Disease predisposing germline mutations in cancer susceptibility genes may consist of large genomic rearrangements, including deletions or duplications that are challenging, to detect and characterize using standard PCR-based mutation screening methods. Such rearrangements range from single exons up to hundreds of kilobases of sequence in size. Array-based comparative genomic hybridization (aCGH)

Transition from Acenocoumarol to Warfarin in a 12-year-old Child.

The types of coumadin anticoagulants registered and available for use differ between countries. Most frequently used coumadin anticoagulants are warfarin and acenocoumarol. Under several specific conditions, transition from one coumarin to another is required. Because of different pharmacokinetic and pharmacodynamic characteristics, the transition from one type of coumarol to another type can be c

Fathers' sense of security during the first postnatal week-A qualitative interview study in Sweden.

BACKGROUND: father's sense of security in the early postnatal period is important for the whole family. An instrument, which measures Parents' Postnatal Sense of Security (the PPSS instrument), is under development. OBJECTIVE: to explore and describe factors, which influence fathers' sense of security during the first postnatal week. METHODS: an explorative design with a qualitative approach was u

Markers of proteolysis, fibrinolysis, and coagulation in relation to size and growth rate of abdominal aortic aneurysms.

We evaluated whether matrix metalloproteinases (MMPs) 2 and 9, their inhibitors, markers for fibrinolysis, and thrombin activation are associated with diameter and growth of abdominal aortic aneurysms (AAAs). Material and Methods: Matrix metalloproteinases 2 and 9, tissue inhibitor of MMPs (TIMP-1), serpine-1, tPa-serpine-1, and activated protein C- protein C inhibitor (APC-PCI) complex were analy

Cause of death in patients with dementia disorders.

Background: Investigations on cause of death may provide valuable information about life expectancy and on conditions of terminal dementia care, which perhaps can be ameliorated. Methods: The autopsy reports were studied on all patients (n = 524; 55.3% females; median age 80 years) with a clinically and neuropathologically diagnosed dementia disorder who underwent a complete autopsy at the Univers
