Social factors related to the clinical severity of influenza cases in Spain during the A (H1N1) 2009 virus pandemic
2013
Abstract Background During the 2009 influenza pandemic, a change in the type of patients most often affected by influenza was observed. The objective of this study was to assess the role of individual and social determinants in hospitalizations due to influenza A (H1N1) 2009 infection. Methods We studied hospitalized patients (cases) and outpatients (controls) with confirmed influenza A (H1N1) 2009 infection. A standardized questionnaire was used to collect data. Variables that might be related to the hospitalization of influenza cases were compared by estimation of the odds ratio (OR) and 95% confidence intervals (CI) and the variables entered into binomial logistic regression models. Resu…
Prevalence of alexithymia in eating disorders in a clinical sample of 800 Mexican patients.
2019
The inability to identify, express feelings, and not distinguish between emotions and bodily sensations, is known as alexithymia. In 1988, it developed The Toronto Alexithymia Scale (TAS-20), consists of 20 items and three factors: a) difficulty of identifying feelings and differences between feelings and bodily sensations; b) difficulty of describing feelings; and c) externally oriented thinking. It's considered that people with eating disorders have specific deficits in identify and communicate their feelings.The present study has as purpose to the instrument validation.It was a cross-sectional study and psychometric character design of a single sample, formed of 435 persons suffering eat…
Health Behavior in Hypochondriasis
2015
The relationship between health behavior and hypochondriasis has not yet been sufficiently examined, as previous studies investigated only individual dimensions of health behavior. In the present study, we extend current literature by examining multiple dimensions of health behavior. One hundred twenty-six participants, consisting of 40 participants with a primary diagnosis of hypochondriasis, 41 participants with a primary diagnosis of anxiety disorder, and 45 healthy controls, completed a multidimensional questionnaire for the assessment of health behavior and other measures for the evaluation of general psychopathology, illness anxiety, depression, and general anxiety. Patients with hypo…
Effect of age in the ciliary muscle during accommodation: Sectorial analysis
2017
Abstract Purpose To compare changes in the ciliary muscle area at different sectors between pre-presbyopic and presbyopic eyes during accommodation by means of an anterior segment optical coherence tomographer (OCT). Methods The anterior ciliary muscle area was measured in 20 healthy and phakic pre-presbyopic eyes, whose mean age was 23.3 ± 4.4 years, and in 20 healthy and phakic presbyopic eyes, whose mean age was 46.5 ± 5.2 years. The relative change in the cross-sectional area of the ciliary muscle was measured at the nasal, inferior, and temporal sectors between 0 and −3 D of vergence, in −1 D step. A linear model was used to assess the correlation of each eye parameter with the accommo…
Age-specific neuromuscular interaction during elderly habitual running
2015
Aim It has been reported that advancing age causes tendons to become more compliant and fascicles length shorter. This could then lead to enhancement of movement efficiency provided that the elderly adults can activate their muscles in the same way as the younger adults (YOUNG) during dynamic movements. This study was designed to examine the age-specific behaviour of the medial gastrocnemius (MG) fascicles and tendinous tissues together with lower-leg muscle activities when the well-trained elderly runners ran on the treadmill at preferred speeds. Methods The well-trained 11 elderly subjects (ELD) who have running experiences and 11 YOUNG were recruited as subjects. While ELD were running o…
Age-related muscle activation profiles and joint stiffness regulation in repetitive hopping
2011
Abstract It is well documented that increasing effort during exercise is characterized by an increase in electromyographic activity of the relevant muscles. How aging influences this relationship is a matter of great interest. In the present study, nine young and 24 elderly subjects did repetitive hopping with maximal effort as well as with 50%, 65%, 75% and 90% intensities. During hopping joint kinematics were measured together with electromyographic activity (EMG) from the soleus, gastrocnemius medialis, gastrocnemius lateralis and tibialis anterior muscles. The results showed that agonist activation increased in both age groups with increasing intensity. The highest jumping efficiency (E…
No evidence for a correlation of glutathione S-tranferase polymorphisms and chronic rhinosinusitis.
2011
OBJECTIVE: Cellular detoxification mechanisms are mandatory for cellular protection against oxidative stress and reactive oxygen species. One major group of antioxidative active enzymes involved in cellular detoxification are the Glutathione S-Transferases (GST). Multiple subtypes like GSTM1, GSTP1, and GSTT1 and variants of them are known, arising from allelic variations of the GST loci. Moreover, functional variants occur in high percentages and have been associated with diseases like bronchial asthma and bronchial hyperresponsiveness. The interplay of oxidative stress, detoxifying genes like GSTs and the genesis of respiratory tract illness is under contradictory debate. In this study, w…
Risk of surgical site infections following hip and knee arthroplasty: Results of the ischia-gisio study
2017
Surgical Site Infection (SSI) is one of the major complications following insertion of hip or knee prosthesis. The aim of the present study was to describe rates of SSIs and associated risk factors during hip and knee prosthesis procedures in Italian hospitals. METHODS: Italian hospitals were invited to join the ISChIA (Surgical Site Infections in Arthroplasty Surgery) project and participated in the study on a voluntary basis. SSI surveillance was performed according to the Hospitals in Europe Link for Infection Control through Surveillance (HELICS) -SSI protocol. The study population consisted of all patients who had a prosthetic knee or hip joint replacement between March 2010 and Februa…
Etiologic Heterogeneity Among Non-Hodgkin Lymphoma Subtypes: The InterLymph Non-Hodgkin Lymphoma Subtypes Project
2014
Non-Hodgkin lymphoma (NHL) is the most common hematologic malignancy and the fifth most common type of cancer in more developed regions of the world (1). Numerous NHL subtypes with distinct combinations of morphologic, immunophenotypic, genetic, and clinical features are currently recognized (2,3). The incidence of NHL subtypes varies substantially by age, sex, and race/ethnicity (4–7). However, the etiological implications of this biological, clinical, and epidemiological diversity are incompletely understood. The importance of investigating etiology by NHL subtype is clearly supported by research on immunosuppression, infections, and autoimmune diseases, which are the strongest and most e…
MicroRNA hsa-miR-4717-5p regulates RGS2 and may be a risk factor for anxiety-related traits
2015
Regulator of G-protein Signaling 2 (RGS2) is a key regulator of G-protein-coupled signaling pathways involved in fear and anxiety. Data from rodent models and genetic analysis of anxiety-related traits and disorders in humans suggest down-regulation of RGS2 expression to be a risk factor for anxiety. Here we investigated, whether genetic variation in microRNAs mediating posttranscriptional down-regulation of RGS2 may be a risk factor for anxiety as well. 75 microRNAs predicted to regulate RGS2 were identified by four bioinformatic algorithms and validated experimentally by luciferase reporter gene assays. Specificity was confirmed for six microRNAs (hsa-miR-1271-5p, hsa-miR-22-3p, hsa-miR-3…
