Alterations in the tear proteome of dry eye patients--a matter of the clinical phenotype.

2013

PURPOSE. Previous studies demonstrated alterations in the tear proteome of dry eye patients. The aim of the present study was to analyze tear protein patterns of dry eye patients considering different clinical phenotypes in order to examine their influence on tear film protein composition. METHODS. We applied a surface-enhanced laser desorption/ ionization-time-of-flight (SELDI-TOF)/matrix-assisted laser desorption/ionization-time-of-flight (MALDI-TOF)/TOF mass spectrometry (MS)‐based strategy to detect/identify candidate biomarkers. Tear samples of 169 patients, enrolled in two independent studies, were analyzed. Patients were subdivided into healthy controls (CTRL: N ¼ 39), aqueous-defici…

Low incidence but poor prognosis of complicated coeliac disease: A retrospective multicentre study.

2013

Abstract Background Coeliac disease is a chronic enteropathy characterized by an increased mortality caused by its complications, mainly refractory coeliac disease, small bowel carcinoma and abdominal lymphoma. Aim of the study was to study the epidemiology of complications in patients with coeliac disease. Methods Retrospective multicenter case–control study based on collection of clinical and laboratory data. The incidence of complicated coeliac disease was studied among coeliac patients directly diagnosed in four Italian centres. Patients referred to these centres after a diagnosis of coeliac disease and/or complicated coeliac disease in other hospitals were therefore excluded. Results B…

Accuracy of two plasma antibody tests and faecal antigen test for non-invasive detection of H. pylori in middle-aged Caucasian general population sam…

2018

The aim of the study was to assess the accuracy of two plasma Helicobacter pylori (H. pylori) antibody test-systems and a stool antigen test (SAT) system in a general population sample in Latvia.Blood and faecal samples were analysed in healthy individuals (40-64 years), referred for upper gastrointestinal endoscopy according to pilot study protocol within a population-based study investigating gastric cancer prevention strategies (GISTAR pilot study). Antibodies to H. pylori were assessed in plasma by latex-agglutination test and enzyme-linked immunosorbent assay (ELISA). H. pylori antigen in faecal samples was detected by a monoclonal enzyme immunoassay-based SAT. Histological assessment …

Early improvement as a predictor of remission and response in schizophrenia: Results from a naturalistic study

2009

AbstractObjectiveTo examine the predictive validity of early improvement in a naturalistic sample of inpatients and to identify the criterion that best defines early improvement.MethodsTwo hundred and forty-seven inpatients who fulfilled ICD-10 criteria for schizophrenia were assessed with the Positive And Negative Syndrome Scale (PANSS) at admission and at biweekly intervals until discharge from hospital. Remission was defined according to the recently proposed consensus criteria, response as a reduction of at least 40% in the PANNS total score from admission to discharge.ResultsReceiver operating characteristic (ROC) analyses showed that early improvement (reduction of the PANSS total sco…

Clinical and prognostic value of 18F-FDG-PET/CT in restaging of pancreatic cancer

2018

Aim The aim of this retrospective multicentre study was to evaluate the clinical and prognostic effect of fluorine-18-fluorodeoxyglucose (18F-FDG)-PET/computed tomography (CT) in the restaging process of pancreatic cancer (PC). Materials and methods Data from patients treated for primary PC, who underwent18F-FDG-PET/CT for suspicious of disease progression, were collected. Accuracy was assessed employing conventional diagnostic procedures, multidisciplinary team case notes, further18F-FDG-PET/CT scans and/or follow-up. Receiver operating characteristic curve and likelihood ratio (LR+/-) analyses were used for completion of accuracy definition. Progression-free survival (PFS) and overall sur…

Neurocognitive diagnosis and cut-off scores of the Screen for Cognitive Impairment in Psychiatry (SCIP-S)

2009

To demonstrate the ability of the Screen for Cognitive Impairment in Psychiatry (SCIP-S) to discriminate between cognitively-impaired individuals and those with adequate functioning in a sample of schizophrenic and bipolar patients, as well as in a control group.The SCIP-S, together with a full neuropsychological battery, was administered to three groups: patients with schizophrenia, patients diagnosed with bipolar disorder I, and controls. The battery scores were used to perform a standardization with respect to the control group and this served to determine the comparison groups (cognitively impaired versus unimpaired) for each of the subtests of the SCIP-S. A full analysis of decision va…

Detection of Depression in Acute Schizophrenia: Sensitivity and Specificity of 2 Standard Observer Rating Scales

2006

Objective: To compare the psychometric properties of the Calgary Depression Rating Scale (CDRS) and the Hamilton Depression Rating Scale (HDRS) for severity assessment of depression in acute schizophrenia. Method: During clinical routine treatment, we investigated 119 inpatients with acute schizophrenia, using the CDRS, the HDRS, and a global 4-point Depression Severity Scale (DEP-SEV). We compared CDRS and HDRS sum scores regarding their diagnostic accuracy, with global severity of depression as the criterion. We estimated sensitivity and specificity on the basis of receiver operating characteristic curves. Results: According to global clinical ratings (DEP-SEV), 31% of patients had no dep…

Exhaled Nitric Oxide Measurement Is Not Useful for Predicting the Response to Inhaled Corticosteroids in Subjects With Chronic Cough

2009

Background Increased concentrations of exhaled nitric oxide (ENO) are identified predominantly in subjects with chronic cough due to conditions that habitually respond well to therapy with inhaled corticosteroids (ICSs). The aim of this study was to assess the usefulness of ENO in predicting the response to ICS therapy in subjects with chronic cough and to determine the relationship between either methacholine or adenosine 5′-monophosphate (AMP) responsiveness and the response to ICS therapy. Methods A total of 43 patients with chronic cough were studied. During the baseline period, ENO measurement, spirometry, and concentration-response studies with both methacholine and AMP were performed…

Parenting in the face of serious illness: Childhood cancer survivors remember different rearing behavior than the general population

2019

Objective A child's cancer diagnosis and treatment affect the whole family. While it has been recognized that parents are an important resource for their children, little is known about the specifics of parenting in the face of serious illness. Methods We used the Recalled Parental Rearing Behavior Questionnaire in a register-based cohort of adult childhood cancer survivors (CCS) (N = 951) and a representative population sample of the same age range (N = 2042). The questionnaire assesses behavior of mothers and fathers with three scales (emotional warmth, rejection/punishment, and control/overprotection) by querying the (former) child. We compared the two groups using general linear models.…

2007

Purpose. The aim of this study was to assess the value of computed tomography (CT) perfusion parameters in differentiating tissue viability in acute stoke patients. Materials and methods. Thirteen patients (mean age 63.3 years) with nonhaemorrhagic stroke underwent multidetector perfusion CT within 3 h of symptom onset. Images were continuously acquired at the basal ganglia over 40 s during injection of 90 ml of iodinated contrast medium injected at a rate of 9 ml/s with a 9-s delay. Z-axis coverage was 20 mm. All patients underwent diffusion-weighted magnetic resonance imaging (DWI) within 12 h of perfusion CT to define the extent of the infarct. Perfusion CT data were analysed in regions …
