[Visiting friends and relatives (VFRs) role on imported malaria: a literature review]
2015
In the last decades, increased numbers of travel to tropical destinations in combination with the enormous influx of immigrants have led to an increased number of imported malaria cases in developed countries. There is a group of immigrants regularly resident in malaria free areas, which travel to malaria endemic countries to visit their friends and relatives (VFRs). VFRs represent a high-risk group of contracting malaria. Publications presenting original data on malaria in VFRs were selected for a literature review.We considered all data regarding prevalence of malaria in VFRs compared to the other groups of travelers, length of trip, group characteristics such as age, sex, country visited…
Avaliação da resposta de acomodação após tarefas visuais próximas usando diferentes dispositivos eletrônicos portáteis
2015
ABSTRACT Purpose: To assess the accommodation response after short reading periods using a tablet and a smartphone as well as determine potential differences in the accommodation response at various stimulus vergences using a Hartmann- Shack aberrometer. Methods: Eighteen healthy subjects with astigmatism of less than 1 D, corrected visual acuity of 20/20 or better, and normal findings in an ophthalmic examination were enrolled. Accommodation responses were obtained under three different conditions: accommodation system of the eye relaxed and visually stressed with a tablet and an smartphone for 10 min, at a distance of 0.25 m from the subject's eyes. Three measurements of accommodation res…
Pain Mechanisms in Peritoneal Diseases Might Be Partially Regulated by Estrogen
2017
To identify factors influencing the differential pain pathogenesis in peritoneal endometriosis (pEM) and peritoneal carcinomatosis in ovarian cancer (pOC), we undertook an experimental study. Tissue samples of 18 patients with pEM, 15 patients with pOC, and 15 unaffected peritoneums as controls were collected during laparoscopy or laparotomy. Immunohistochemical stainings were conducted to identify nerve fibers and neurotrophins in the tissue samples. Additionally, 23 pEM fluids, 25 pOC ascites fluids, and 20 peritoneal fluids of patients with myoma uteri as controls were collected. In these fluids, the expression of neurotrophins was evaluated. The effects of peritoneal fluids and ascites …
Pleural Mesothelial Cells Express Both BLT2 and PPARα and Mount an Integrated Response to Pleural Leukotriene B4
2008
Abstract Leukotriene B4 (LTB4) plays a crucial role in the recruitment of neutrophils into the pleural space. We identified for the first time the mechanisms by which LTB4 interacts with mesothelial cells and recruits neutrophils in the pleural compartment. Primary pleural mesothelial cells express both the proinflammatory receptor for LTB4 BLT2, and the anti-inflammatory receptor for LTB4, PPARα. Parapneumonic pleural effusions highly increase BLT2 expression and, via BLT2 activation, increase the adhesion between mesothelial cells and neutrophils and the expression of ICAM-1 on mesothelial cells. The block of PPARα further increases both cell adhesion and ICAM-1 expression. BLT2 activatio…
Hereditary angioedema in children and adolescents - A consensus update on therapeutic strategies for German-speaking countries.
2020
Background/methods At a consensus meeting in August 2018, pediatricians and dermatologists from German-speaking countries discussed the therapeutic strategy for the treatment of pediatric patients with type I and II hereditary angioedema due to C1 inhibitor deficiency (HAE-C1-INH) for Germany, Austria, and Switzerland, taking into account the current marketing approval status. HAE-C1-INH is a rare disease that usually presents during childhood or adolescence with intermittent episodes of potentially life-threatening angioedema. Diagnosis as early as possible and an optimal management of the disease are important to avoid ineffective therapies and to properly treat swelling attacks. This art…
Physical activity and breast cancer risk by pathological subtype
2017
Abstract Objective To examine the influence of physical activity on breast cancer risk and evaluate whether adherence to international recommendations is associated with a decreased risk. Methods This is a multicenter matched case-control study where 698 pairs completed a physical activity questionnaire. Recreational physical activity during the last year was quantified in metabolic equivalent hours per week (MET-h/week) and categorized in activities of moderate (3.0–5.9 MET) and vigorous (>6 MET) intensity. The adherence to World Cancer Research Fund and the American Institute for Cancer Research recommendation was also assessed. The association with breast cancer risk, overall and by path…
Soluble intercellular adhesion molecule-1 levels in patients with psoriasis.
1993
A newly developed ELISA was used to detect and quantify the presence of a soluble form of intercellular adhesion molecule-1 (sICAM-1) in the circulation of healthy individuals compared with patients with psoriasis vulgaris. Seventeen psoriatic patients were studied. The extent of skin lesions was rated by the psoriasis area and severity index (PASI). Seventeen age- and sex-matched healthy individuals served as controls. Serum levels were measured by an ELISA technique utilizing an anti-ICAM-1 murine monoclonal antibody bound to the solid phase, and a second, peroxidase-conjugated monoclonal antibody reacting with sICAM-1. Serum levels in controls were 358.8 +/- 87.9 ng/ml sICAM-1, and 480.5…
Involvement of leucocyte/endothelial cell interactions in anorexia nervosa.
2015
Background Anorexia nervosa is a common psychiatric disorder in adolescence and is related to cardiovascular complications. Our aim was to study the effect of anorexia nervosa on metabolic parameters, leucocyte–endothelium interactions, adhesion molecules and proinflammatory cytokines. Materials and Methods This multicentre, cross-sectional, case–control study employed a population of 24 anorexic female patients and 36 controls. We evaluated anthropometric and metabolic parameters, interactions between leucocytes polymorphonuclear neutrophils (PMN) and human umbilical vein endothelial cells (HUVEC), proinflammatory cytokines such as tumour necrosis factor alpha (TNF-α) and interleukin-6 (IL…
Endometrial receptivity is affected in women with high circulating progesterone levels at the end of the follicular phase: a functional genomics anal…
2011
Elevated serum progesterone levels at the end of the follicular phase in controlled ovarian stimulation (COS) leads to a poorer ongoing pregnancy rate in IVF cycles due to reduced endometrial receptivity. The objective of this study was to use microarray technology to compare endometrial gene expression profiles at the window of implantation according to the levels of circulating progesterone.For this prospective cohort study, microarray data were obtained from endometrial biopsies from 12 young healthy oocyte donors undergoing COS with pituitary suppression by either gonadotrophin-releasing hormone (GnRH) agonists or antagonists, and recombinant FSH. On the day of recombinant chorionic gon…
Alterations in the expression of PSA-NCAM and synaptic proteins in the dorsolateral prefrontal cortex of psychiatric disorder patients.
2012
Alterations in the structure and physiology of the prefrontal cortex (PFC) have been found in different psychiatric disorders and some of them involve inhibitory networks, especially in schizophrenia and major depression. Changes in the structure of these networks may be mediated by the polysialylated neural cell adhesion molecule (PSA-NCAM), a molecule related to neuronal structural plasticity, expressed in the PFC exclusively by interneurons. Different studies have found that PSA-NCAM expression in the hippocampus and the amygdala is altered in schizophrenia, major depression and animal models of these disorders, in parallel to changes in the expression of molecules related to inhibitory …
