The construction of a subset of ICNP® for patients with dementia: a Delphi consensus and a group interview study

2015

Background The International Classification for Nursing Practice (ICNP®) 2013 includes over 4000 concepts for global nursing diagnoses, outcomes and interventions and is a large and complex set of standardised nursing concepts and expressions. Nurses may use subsets from the ICNP as concepts and expressions for research, education and clinical practice. The objective of this study was to identify and validate concepts for an ICNP subset to guide observations and documentation of nursing care for patients with dementia. Method The process model for developing ICNP subsets was followed, according to the guidelines adopted by the International Council of Nursing (ICN). To identify relevant and…

Abstract Background Clinical management ranges from surveillance or curettage to wide resection for atypical to higher-grade cartilaginous tumours, respectively. Our aim was to investigate the performance of computed tomography (CT) radiomics-based machine learning for classification of atypical cartilaginous tumours and higher-grade chondrosarcomas of long bones. Methods One-hundred-twenty patients with histology-proven lesions were retrospectively included. The training cohort consisted of 84 CT scans from centre 1 (n=55 G1 or atypical cartilaginous tumours; n=29 G2-G4 chondrosarcomas). The external test cohort consisted of the CT component of 36 positron emission tomography-CT scans from…

Should We Screen for <i>Helicobacter pylori</i> to Prevent Gastric Cancer?

2007

Although the strategy for <i>Helicobacter pylori</i> infection management is well defined and quite well followed in a number of situations, including peptic ulcer disease, the issue of <i>H. pylori</i> screening and eradication in the general population still remains. The following debate attempts to find the answer of whether or not <i>H. pylori</i> screening should be performed in the asymptomatic population for preventing gastric cancer. As yet, there is no final evidence-based consensus about the need to screen for <i>H. pylori</i> in order to decrease the incidence of gastric cancer.

Mitochondrial complex I impairment in leukocytes from polycystic ovary syndrome patients with insulin resistance.

2009

Insulin resistance is a feature of polycystic ovary syndrome (PCOS) and is related to mitochondrial function.Our objective was to assess mitochondrial function by evaluating mitochondrial oxygen (O(2)) consumption, reactive oxygen species (ROS) production, levels of glutathione (GSH), the oxidized glutathione/GSH ratio, TNFalpha levels, and membrane potential. Additionally, we have evaluated mitochondrial complex I as a target of the oxidative stress responsible for PCOS in polymorphonuclear cells.This was a prospective controlled study conducted in an academic medical center.The study population consisted of 20 lean reproductive-age women with PCOS and 20 body composition-matched controls.…

Influence of various preseason training in elite youth soccer players

2013

Aim Endurance capacity of each individual soccer player can notably influence a team’s success. The opinion about the necessity of generic endurance specific training in soccer, especially in adolescent athletes, still varies widely.

Viridans streptococcal infective endocarditis associated with fixed orthodontic appliance managed surgically by mitral valve plasty

2018

Abstract Rationale: Streptococcus viridans, a heterogeneous group of alpha-hemolytic streptococci, is part of the normal flora of the mouth, usually responsible for dental caries (Streptococcus mutans, Streptococcus sanguinis), and pericoronitis, as well as for subacute infective endocarditis. They are responsible for 40-60% of the endocarditis cases occurring on the normal valves, especially in male patients and over 45 years of age. A change in the bacterial flora of the oral cavity is taking part after orthodontic fixed appliances are introduced into the oral cavity, change that is associated with an increased concentration of the acidogenic bacteria. Bacteraemia is the consequence of or…

Identification of the yolk receptor protein in oocytes of Nereis virens (Annelida, Polychaeta) and comparison with the locust vitellogenin receptor

1992

In oviparous animals large amounts of yolk proteins of extraovarian origin are accumulated by developing oocytes during vitellogenesis. The yolk protein precursors, the vitellogenins (VTG), are transported into the oocytes by receptor-mediated endocytosis. In oocytes of the polychaetous annelid, Nereis virens, the receptor protein for VTG was visualized by ligand blotting studies as a protein with an apparent molecular mass of 190 kDa under non-reducing conditions. Anti-Locusta VTG receptor antibodies recognize the Nereis VTG receptor protein. The Nereis VTG receptor protein binds Locusta and Schistocerca VTG; the VTG receptor proteins of both locust species bind the Nereis vitellin. These …

The effects of experimentally manipulated yolk androgens on growth and immune function of male and female nestling collared flycatchers Ficedula albi…

2009

Hormone-mediated maternal effects may be an important mechanism for adjusting offspring phenotype to particular requirements of the environment. We manipulated the levels of testosterone and androstenedione in the yolk of collared flycatcher Ficedula albicollis eggs to investigate the effects of pre-natal exposure to androgens on growth and immune function. Androgen treatment tended to reduce the growth of males, and enhance the growth of females, as indicated by significant interaction between sex and androgen treatment. Cellular immune function was not affected by androgen treatment or sex. Survival of nestlings until fledging was not related to androgen treatment. Our results indicate th…

Eye fluke-induced cataract formation in fish: quantitative analysis using an ophthalmological microscope

2004

We examined the parasite-induced cataract formation in rainbow trout (Oncorhynchus mykiss) using slit-lamp microscopy to determine the relationship between cataract intensity and number of Diplostomum spathaceum parasites that were established in the lens. Cataract intensity increased significantly with parasite burden, but was also affected by the pattern of exposure to the parasite cercariae. The slit-lamp methodology proved useful in scoring the cataracts since it provides a 3-dimensional view into the lens and gives an actual picture of the location and intensity of the cataracts, which allows detailed investigations of mechanisms underlying cataract formation in various fish species. P…

Electronystagmography in the diagnosis of central vertigo.

2011

Objective: Determine the efficacy and applicability of electronystagmography (ENG) testing in the differential diagnosis between peripheral and central vertigo, through the visual-vestibular interaction test, in patients with vertigo.Method: Patients were submitted to ENG recording. Patients sat on a rotatory chair, which was placed in the middle of a rotary rotatory cylindrical chamber. The rotatory chamber was driven by a direct current engine, which turned it clockwise and counterclockwise, and its internal area was covered with 32 black vertical contrast.Results: All patients underwent rotatory vestibular stimulation by Stop test (VOR), optokinetic stimulation (OKN), and contemporary ro…
