Mortality in multiple sclerosis: a review
2008
This work was undertaken to evaluate studies on mortality caused by multiple sclerosis (MS), to evaluate if useful inferences can be drawn from survival studies that can be applied to clinical practice. A literature search was carried out to find epidemiological studies on MS prognosis, survival, mortality and causes of death relevant to our aim. The World Health Organization (WHO) reports on worldwide cause-specific mortality were also considered. Studies were evaluated according to the duration of the follow-up study, the year of publication and the methodology used. We evaluated MS survival from a methodological point of view and considered if time trends could be drawn from study result…
Sleep disordered breathing in patients with cardiovascular comorbidities hospitalized for pulmonary disease
2015
Sleep disordered breathing (SDB) is often overlooked in hospitalized patients. We screened consecutive patients with cardiovascular (CV) comorbidities hospitalized for respiratory problems to study SDB prevalence and type. Patients did not refer typical clinical signs of SDB. Patients (n=34, 21 M, mean age±SD 71±12 yr, BMI: 31.9±5.8 kg/m2) were studied by polygraphy (SomnoLab, Weinmann, Germany) 4.5±3.2 days after admission for COPD exacerbation (COPD-E, n=20), pleural effusion (n=2), asthma exacerbation (n=2) or other causes (n=10). On admission, 18 patients showed respiratory failure (RF, hypoxemic: n=9, hypercapnic: n=9). CV comorbidities (1.7±0.8/patient) were: hypertension (n= 27), hea…
AB0929 Balance in fibromyalgia is not related with lower limb strength
2017
Background Postural control, that depends on many sensory contributors and motor skills, is altered in people with fibromyalgia (FM) 1–3. Knowing those contributors that could be impaired in this population is important to design an appropriate balance therapy. Objectives Due to the fact that people with FM use to present a strength loss 7, our main goal was to explore the relation between postural control and lower limb strength in this population. Further, the sensory inputs contributors to the postural control were assessed. Methods A cross-sectional study was conducted in a sample of 40 FM patients. A force platform was used to assess postural control under five bipedal conditions: i) e…
Sustained Responses and Resistance to Imatinib Mesylate in the First 173 Chronic Myeloid Leukemia Patients Accrued by the SCREEN Multicenter Study: F…
2009
Abstract Abstract 4276 Introduction Imatinib mesylate (IM) has shown unprecedented effectiveness in the treatment of Chronic Myeloid Leukemia (CML) patients (pts) in the chronic phase of the disease. As most of the data concerning the efficacy of the drug derive either from a single sponsored trial or from single institution reports, we decided to accrue all CML pts diagnosed in the Italian region of Sicily to the observational SCREEN (Siciliy CML Regional Enterprise) study, to evaluate the hematological, cytogenetic and molecular responses of this unselected population to IM. Patients and Methods Although the study is still ongoing, 173 consecutive CML pts have been enrolled between Januar…
Anthropometric measurements and nutritional assessment in autism spectrum disorders: A systematic review
2015
Abstract Adequate nutrient intake is essential for health. Due to food selectivity and restrictive diets, people with autism spectrum disorder (ASD) may have impaired nutritional status, which could affect their growth. We present a systematic review of publications (1970–2013) on anthropometric measurements and nutritional assessment in this population. The limited research published on growth and nutritional status has found contradictory results. Nutritional assessment has indicated limited food variety in the ASD population but has not confirmed significant differences with respect to recommended intakes or controls. In addition to the lack of control groups, studies in this area have s…
Survival with Cardiac-Resynchronization Therapy in Mild Heart Failure
2014
BACKGROUND The Multicenter Automatic Defibrillator Implantation Trial with Cardiac Resynchronization Therapy (MADIT-CRT) showed that early intervention with cardiac-resynchronization therapy with a defibrillator (CRT-D) in patients with an electrocardiographic pattern showing left bundle-branch block was associated with a significant reduction in heart-failure events over a median follow-up of 2.4 years, as compared with defibrillator therapy alone. METHODS We evaluated the effect of CRT-D on long-term survival in the MADIT-CRT population. Post-trial follow-up over a median period of 5.6 years was assessed among all 1691 surviving patients (phase 1) and subsequently among 854 patients who w…
Mechanism of reperfusion damage after thrombolysis and ‘direct PTCA’
1997
Summary There is general agreement between cardiologists, that reperfusion of the infarct related coronary artery (PTCA) is the method of choice for the treatment of an acute myocardial infarction. However, the method utilized for inducing a rapid and complete reperfusion is still discussed. Even if thrombolysis will remain the method of choice for the major part of the population, part of the patient cohort with acute infarction will be treated by direct PTCA. Rapid reperfusion of ischemic myocardium reduces infarct size by limiting infarct extension into the entire area at risk, although a reperfusion damage is induced in the core ischemic area. This reperfusion damage has been convincing…
Glutathione, GlutathioneS-Transferase α and π, and Aldehyde Dehydrogenase Content in Relationship to Drug Resistance in Ovarian Cancer
1997
Glutathione, glutathione S-transferases alpha and pi, and aldehyde dehydrogenase are associated with resistance to carboplatin and/or cyclophosphamide in cell lines. Therefore, we examined whether the expression of these factors in ovarian cancer tissue specimens is associated with resistance of the patients to combination chemotherapy with cyclophosphamide/carboplatin. Ovarian cancer tissue specimens were taken intraoperatively from 139 patients and frozen in liquid nitrogen, and the contents of glutathione S-transferases alpha and pi, total glutathione, and aldehyde dehydrogenase activity were determined. No association between the levels of glutathione S-transferases alpha and pi or alde…
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.…
Specific mutations of the RET proto-oncogene are related to disease phenotype in MEN 2A and FMTC.
1994
We have analysed 118 families with inherited medullary thyroid carcinoma (MTC) for mutations of the RET proto-oncogene. These included cases of multiple endocrine neoplasia types 2A (MEN 2A) and 2B (MEN 2B) and familial MTC (FMTC). Mutations at one of 5 cysteines in the extracellular domain were found in 97% of patients with MEN 2A and 86% with FMTC but not in MEN 2B patients or normal controls. 84% of the MEN2A mutations affected codon 634. MEN 2A patients with a Cys634 to Arg substitution had a greater risk of developing parathyroid disease than those with other codon 634 mutations. Our data show a strong correlation between disease phenotype and the nature and position of the RET mutatio…
