SOX2 expression diminishes with ageing in several tissues in mice and humans.
2017
SOX2 (Sex-determining region Y box 2) is a transcription factor expressed in several foetal and adult tissues and its deregulated activity has been linked to chronic diseases associated with ageing. Nevertheless, the level of SOX2 expression in aged individuals at the tissue level has not previously been examined. In this work, we show that SOX2 expression decreases significantly in the brain with ageing, in both humans and rodents. The administration of resveratrol for 6 months in mice partly attenuated this reduction. We also identified an age-related decline in SOX2 mRNA and protein expression in several other organs, namely, the lung, heart, kidney, spleen and liver. Moreover, periphera…
Effect of gene-gene and gene-environment interactions associated with antituberculosis drug-induced hepatotoxicity.
2017
This study evaluated the association between environmental factors and genetic variations in enzymes that metabolize antituberculosis (anti-TB) drugs [arylamine N-acetyltransferase 2, cytochrome P450 2E1 (CYP2E1), glutathione S-transferase theta 1 (GSTT1), and glutathione S-transferase mu 1] with antituberculosis drug-induced hepatotoxicity (ATDH). We also investigated the potential gene-gene and gene-environment interactions as well as their association with ATDH development in a population of hospitalized TB patients from Buenos Aires.We investigated 364 TB patients who received anti-TB drugs. Physicians collected demographic and clinical data to identify environmental risk factors for AT…
Could university training and a proactive attitude of coworkers be associated with influenza vaccination compliance? A multicentre survey among Itali…
2016
Background Although influenza vaccination has been demonstrated to be safe and effective, vaccination coverage rates among health care workers and among medical residents appear generally low. Several investigations have been performed worldwide to analyze the healthcare workers’ educational deficiencies. This multicentre survey aimed to investigate at a nationwide level training quality and work environment associated with seasonal influenza vaccination uptake among Italian medical residents. Methods A retrospective cohort study was carried out from April 2012 to June 2012 on medical residents regularly attending the post-graduate medical schools of 18 Italian Universities via an anonymous…
When do myopia genes have their effect? Comparison of genetic risks between children and adults
2016
Item does not contain fulltext Previous studies have identified many genetic loci for refractive error and myopia. We aimed to investigate the effect of these loci on ocular biometry as a function of age in children, adolescents, and adults. The study population consisted of three age groups identified from the international CREAM consortium: 5,490 individuals aged 25 years. All participants had undergone standard ophthalmic examination including measurements of axial length (AL) and corneal radius (CR). We examined the lead SNP at all 39 currently known genetic loci for refractive error identified from genome-wide association studies (GWAS), as well as a combined genetic risk score (GRS). …
Neuropeptide Y (NPY) in cerebrospinal fluid from patients with Huntington's Disease: increased NPY levels and differential degradation of the NPY1-30…
2016
Huntington's disease (HD) is an inherited and fatal polyglutamine neurodegenerative disorder caused by an expansion of the CAG triplet repeat coding region within the HD gene. Progressive dysfunction and loss of striatal GABAergic medium spiny neurons (MSNs) may account for some of the characteristic symptoms in HD patients. Interestingly, in HD, MSNs expressing neuropeptide Y (NPY) are spared and their numbers is even up-regulated in HD patients. Consistent with this, we report here on increased immuno-linked NPY (IL-NPY) levels in human cerebrospinal fluid (hCSF) from HD patients (Control n = 10; early HD n = 9; mid HD n = 11). As this antibody-based detection of NPY may provide false pos…
Long-term outcomes and predictive ability of non-invasive scoring systems in patients with non-alcoholic fatty liver disease.
2021
[Background & Aims] Non-invasive scoring systems (NSS) are used to identify patients with non-alcoholic fatty liver disease (NAFLD) who are at risk of advanced fibrosis, but their reliability in predicting long-term outcomes for hepatic/extrahepatic complications or death and their concordance in cross-sectional and longitudinal risk stratification remain uncertain.
Smoking may increase the risk of hospitalization due to influenza.
2016
Background: Smoking may facilitate influenza virus infections and their severity. The objective was to investigate the risk of hospitalization due to influenza in Spanish smokers and ex-smokers. Methods: We carried out a multicentre, case-control study in 2011. Cases [patients a parts per thousand yen 18 years hospitalized > 24 h with real time polymerase chain reaction (RT-PCR)-confirmed influenza] were selected from 29 Spanish hospitals. For each case, we selected an outpatient aged a parts per thousand yen 18 years with RT-PCR-confirmed influenza matched by age (+/- 5 years), date of hospitalization of the case (+/- 10 days) and province of residence. We collected epidemiological variabl…
Secukinumab efficacy in the treatment of nail psoriasis: a case series
2018
Nail involvement is frequent in patients with psoriasis, especially those with psoriatic arthritis (PsA), and can significantly impair quality of life (QoL). It is typically difficult to treat compared with skin lesions, although several conventional treatment options are available. The aim of this article is to describe our experience in the treatment of nail psoriasis with secukinumab in a case series. Fifteen patients (11 males and 4 females), with moderate-severe plaque psoriasis and nail psoriasis, eligible for systemic therapy, and received secukinumab. The Psoriasis Area and Severity Index (PASI) and body surface area (BSA) assessed cutaneous severity. Nail Psoriasis Severity Index (…
Antiepileptic drug reduction and increased risk of stimulation-evoked focal to bilateral tonic-clonic seizure during cortical stimulation in patients…
2017
Introduction: Stimulation-evoked focal to bilateral tonic-clonic seizure (FBTCS) can be a stressful and possibly harmful adverse event for patients during cortical stimulation (CS). We evaluated if drug load reduction of anti epileptic drugs (AEDs) during CS increases the risk of stimulation-evoked FBTCS. Material and methods: In this retrospective cohort study, we searched our local database for patients with drug resistant epilepsy who underwent invasive video-EEG monitoring and CS in the University Hospital la Fe Valencia from January 2006 to November 2016. The AED drug load was calculated with the defined daily dose. We applied a uni- and multivariate logistic regression model to estima…
Resting Energy Expenditure and Substrate Oxidation in Malnourished Patients With Type 1 Glycogenosis.
2019
Abstract Context Type 1a and 1b glycogenosis [glycogen storage disorder (GSD)1a, GSD1b] are rare diseases generally associated with malnutrition. Although abnormal substrate oxidation rates and elevated energy expenditures might contribute to malnutrition, this issue has not been investigated. Objective To investigate whether abnormal resting energy expenditure (REE) and substrate oxidation rate characterize patients with GSD1. Design Cross-sectional study Setting Outpatient referral center for rare diseases and laboratory of clinical nutrition at the University Hospital of Palermo Patients Five consecutive patients with GSD1 (4 type a, 1 type b; 3 men, 2 women; age range, 19 to 49 years) M…
