Hematopoietic Peripheral Circulating Blood Stem Cells As an Independent Marker of Good Transfusion Management in Patients with Beta-Thalassemia
2015
Abstract Aim Aim of the current study was to prospectively evaluate the potential role of peripheral circulating CD34+ stem cells as new independent marker of appropriate hemopoietic balance in patients with thalassemia major and intermedia. Materials and methods Peripheral blood samples from patients with thalassemia major (TM) and intermedia (TI) were drawn. Peripheral circulating CD34+ stem cells, CF-GEMM, CFU-GM and BFU-GM were assayed with monoclonal antibodies for CD34 and clonogenic tests, according to standard procedures and ISHAGE method (BD stem cell enumeration kit, Becton Dickinson; H4434, Stem Cell Technology). Demographic and clinical data were recorded from each enrolled subj…
Nachweis von SLA/LP-Autoantikörpern bei Patienten mit primär biliärer Zirrhose als Marker für eine sekundäre autoimmune Hepatitis (Overlapsyndrom)
2001
BACKGROUND AND OBJECTIVE The aim of this study was to evaluate whether the presence of SLA/LP-autoantibodies in PBC-patients gives evidence for a secondary AIH, also called AIH/PBC-overlap-syndrome. PATIENTS AND METHODS Out of 233 consecutive patients with PBC who had been followed between October 1980 and April 2000, we evaluated the data of anti-SLA/LP-positive patients and compared them to patients with an anti-SLA/LP-negative AIH/PBC overlap syndrome as well as to patients with a classical course of AIH and PBC. RESULTS In total we could identify nine PBC patients with anti-SLA/LP antibodies (six women/three men) or 3.9% of the study population, Anti-SLA/LP-positive PBC patients were sl…
Tobacco use in lung cancer (LC) patients (p) in Spain
2019
Abstract Background Tobacco use, mainly as cigarette smoking, is the leading cause of lung cancer. Eighty-five percent of LC occur in smokers. Understanding the Spanish smoking habits allows the government to design health care policies against this consumption. To do so, the Grupo Espanol de Cancer de Pulmon (Spanish Lung Cancer Group) made this analysis within the context of the Thoracic Tumor Registry (TTR). Methods The TTR is an observational cohort multicenter study in Spain. The study is conducted according to the Declaration of Helsinki and approved by the institutional review board of each participating site. The registry was approved by the Spanish Drug Agency, as a non-post-author…
Preparando el escenario para dejar de fumar en el paciente con Trastorno Bipolar: intervención breve en la práctica clínica
2018
Tobacco consumption is the main preventable factor of mortality in smokers with bipolar disorder (BD), and any possible solutions are often blocked by prejudices over desire, and the possibilities and risks for these patients in giving up tobacco consumption. Adults with BD were recruited at 8 Mental Health Centres. Smokers were evaluated before and after a brief intervention based on the 3 A’s and classified into a ‘Stage of Change’ (SOC) and their ‘Readiness to Change’ (RTC). A multiple linear regression was used to analyze the progression in their RTC and the independent effect of different variables (pharmacological treatment, history of psychotic symptoms, current anxiety symptoms, wil…
Smoking Cessation in Individuals with Depression
1999
Current, historical and subclinical depression have been linked to a high incidence of cigarette smoking and smoking cessation relapse. This review discusses the efficacy, suitability and other treatment issues involved in using nicotine replacement therapy, antidepressant treatment and cognitive-behavioural interventions to help depressed smokers quit smoking. It is recommended that prior to choosing a smoking cessation treatment regimen, assessment should be made of: (i) current and past history of depression; (ii) nicotine dependency; and (iii) other risk factors (e.g. family history of depression, past difficulty in quitting) for relapse. For those individuals who are highly nicotine de…
Performance and Specificity of 6 Immunoassays for TSH Receptor Antibodies: A Multicenter Study
2017
Background: The measurement of TSH receptor (TSHR) antibodies is warranted for diagnosis of Graves’ disease (GD). Objective: The performance, detection sensitivity, and specificity of 6 TSHR immunoassays were compared. Methods: Two bioassays and 4 binding assays (Kronus, Immulite, Kryptor, Dynex) were compared in a dilution study performed in patients with autoimmune thyroid disease. Both bioassays were compared to 2 binding assays using stimulatory (M22) and blocking (K1–70) monoclonal antibody (MAb) mixtures. Results: Thirty samples from stimulatory (TSAb)-positive/blocking (TBAb)-negative patients with GD were diluted serially and measured in all assays. Samples were positive until dilut…
Thyrotropin Receptor Blocking Antibodies.
2018
AbstractAutoantibodies (Ab) against the thyroid-stimulating hormone receptor (TSHR) are frequently found in autoimmune thyroid disease (AITD). Autoantibodies to the TSHR (anti-TSHR-Ab) may mimic or block the action of TSH or be functionally neutral. Measurement of anti-TSHR-Ab can be done either via competitive-binding immunoassays or with functional cell-based bioassays. Antibody-binding assays do not assess anti-TSHR-Ab functionality, but rather measure the concentration of total anti-TSHR binding activity. In contrast, functional cell-based bioassays indicate whether anti-TSHR-Ab have stimulatory or blocking activity. Historically bioassays for anti-TSHR-Ab were research tools and were u…
Combined effects of aging and a pro-diabetic diet on retinal function in a murine model of aging of the human eye
2009
; Purpose: Improvement of life expectancy and changes in the dietary behaviour of developed populations are accompanied with the prevalence of diabetes and age-related ocular pathologies. Aging of the retina is characterized by accumulation of lipids at the basement of the retinal pigment epithelium - Bruch’s membrane complex.Meanwhile increased oxidative stress is one of the features of aging and diabetes. A fructose-rich diet induces insulin resistance and hypertriglyceridemia, mimicking diabetes. The goal of our study was to evaluate the effects of a pro-diabetic fructose-enriched diet on the retinal function of the ApoB100,LDLR-/- mice, a murine model of aging of the human eye. Methods…
The Relationship between the Transforming Growth Factor β1 T29C Gene Polymorphism and Left Ventricular Geometry and Function in Hypertensive Subjects
2009
The distribution of the T29C TGFβ1 gene polymorphism was analyzed in 198 hypertensives with left ventricular hypertrophy (LVH) and in 235 hypertensives without LVH. Circulating TGFβ1 levels, procollagen type III levels, microalbuminuria, and left ventricular geometry and function were evaluated in all the hypertensives with LVH subgrouped according to T29C TGFβ1 gene polymorphism. Circulating TGFβ1 was evaluated by ELISA technique, procollagen type III by a specific radioimmunoassay, microalbuminuria by radioimmunoassay, and left ventricular geometry and function by echocardiography. All groups were comparable for gender, age, and sex. Regarding T29C TGFβ1 gene polymorphism, prevalence of T…
Five Interpersonal Factors Are Predictive of the Response to Treatment of Major Depression With Antidepressants in Primary Care
2018
Introduction: Factors relating to the interpersonal relationship between the patient and their physician and social environment are important components, which contribute to their response to treatment for major depressive disorder. This study aimed to assess the influence of optimism, perfectionism, therapeutic alliance, empathy, social support, and adherence to medication regimen in the response to antidepressant treatments in the context of normal primary care clinical practice.Method: We conducted a prospective study in which 24 primary care physicians administered sertraline or escitalopram to 89 patients diagnosed with major depressive disorder. The response to treatment and remission…
