DNA multigene characterization of Fasciola hepatica and Lymnaea neotropica and its fascioliasis transmission capacity in Uruguay, with historical cor…

2017

Background Fascioliasis is a pathogenic disease transmitted by lymnaeid snails and recently emerging in humans, in part due to effects of climate changes, anthropogenic environment modifications, import/export and movements of livestock. South America is the continent presenting more human fascioliasis hyperendemic areas and the highest prevalences and intensities known. These scenarios appear mainly linked to altitude areas in Andean countries, whereas lowland areas of non-Andean countries, such as Uruguay, only show sporadic human cases or outbreaks. A study including DNA marker sequencing of fasciolids and lymnaeids, an experimental study of the life cycle in Uruguay, and a review of hum…

SARS-CoV-2 infection risk assessment in the endometrium: viral infection-related gene expression across the menstrual cycle

2020

Objective To determine the susceptibility of the endometrium to infection by—and thereby potential damage from—SARS-CoV-2. Design Analysis of SARS-Cov-2 infection-related gene expression from endometrial transcriptomic data sets. Setting Infertility research department affiliated with a public hospital. Patient(s) Gene expression data from five studies in 112 patients with normal endometrium collected throughout the menstrual cycle. Intervention(s) None. Main Outcome Measure(s) Gene expression and correlation between viral infectivity genes and age throughout the menstrual cycle. Result(s) Gene expression was high for TMPRSS4, CTSL, CTSB, FURIN, MX1, and BSG; medium for TMPRSS2; and low for…

Increased survival of honeybees in the laboratory after simultaneous exposure to low doses of pesticides and bacteria

2018

Recent studies of honeybees and bumblebees have examined combinatory effects of different stressors, as insect pollinators are naturally exposed to multiple stressors. At the same time the potential influences of simultaneously occurring agricultural agents on insect pollinator health remain largely unknown. Due to different farming methods, and the drift of applied agents and manure, pollinators are most probably exposed to insecticides but also bacteria from organic fertilizers at the same time. We orally exposed honeybee workers to sub-lethal doses of the insecticide thiacloprid and two strains of the bacterium Enterococcus faecalis, which can occur in manure from farming animals. Our re…

Changing the education paradigm in oncology: ESO masterclass, 17 years of continuous success

2020

In this review, we summarize the history of the 41 Masterclasses in Clinical Oncology (MCO) organized by ESO or ESO-ESMO during the last 17 years. MCOs have been held in five different geographical regions including: a) Central Europe, b) Eastern Europe and Balkans, c) Baltic and Euroasia, d) Arab World and Southern European Countries and e) Latin America. More than 2.000 young oncologists have attended and more than 250 distinguished faculty members have actively participated. The program exposes students to sessions covering all major tumors ("big killers") and to spotlights updating information on various important cancers and related topics. Participants are able to present their own cl…

The membrane-bound O-acyltransferase domain-containing 7 variant rs641738 increases inflammation and fibrosis in chronic hepatitis B.

2017

Chronic hepatitis B (CHB) is characterized by hepatic inflammation that promotes progression to cirrhosis and predisposes to the development of hepatocellular carcinoma (HCC). Subtle interindividual genetic variation as well as viral and environmental factors interact to determine disease progression between individuals. Recently, the rs641738 membrane-bound O-acyltransferase domain-containing 7 (MBOAT7) polymorphism was demonstrated to influence histological liver damage in alcoholic liver disease, nonalcoholic fatty liver disease, and hepatitis C, but no data are available for CHB. We evaluated rs641738 influence on disease severity in a cohort of 1,101 patients with CHB. Forty-two patien…

Impact of parental over- and underweight on the health of offspring.

2019

Parental excess weight and especially pregestational maternal obesity and excessive weight gain during pregnancy have been related to an increased risk of metabolic (obesity, type 2 diabetes, cardiovascular disease, metabolic syndrome) and nonmetabolic (cancer, osteoporosis, asthma, neurologic alterations) diseases in the offspring, probably mediated by epigenetic mechanisms of fetal programming. Maternal underweight is less common in developed societies, but the discrepancy between a poor nutritional environment in utero and a normal or excessive postnatal food supply with rapid growth catch-up appears to be the main candidate mechanism of the development of chronic diseases during the off…

Heterozygous deletion of the LRFN2 gene is associated with working memory deficits

2016

International audience; Learning disabilities (LDs) are a clinically and genetically heterogeneous group of diseases. Array-CGH and high-throughput sequencing have dramatically expanded the number of genes implicated in isolated intellectual disabilities and LDs, highlighting the implication of neuron-specific post-mitotic transcription factors and synaptic proteins as candidate genes. We report a unique family diagnosed with autosomal dominant learning disability and a 6p21 microdeletion segregating in three patients. The 870 kb microdeletion encompassed the brain-expressed gene LRFN2, which encodes for a synaptic cell adhesion molecule. Neuropsychological assessment identified selective w…

Genetic Variation in HSD17B13 Reduces the Risk of Developing Cirrhosis and Hepatocellular Carcinoma in Alcohol Misusers.

2020

Background and aims Carriage of rs738409:G in patatin-like phospholipase domain containing 3 (PNPLA3) is associated with an increased risk for developing alcohol-related cirrhosis and hepatocellular carcinoma (HCC). Recently, rs72613567:TA in hydroxysteroid 17-beta dehydrogenase 13 (HSD17B13) was shown to be associated with a reduced risk for developing alcohol-related liver disease and to attenuate the risk associated with carriage of PNPLA3 rs738409:G. This study explores the risk associations between these two genetic variants and the development of alcohol-related cirrhosis and HCC. Approach and results Variants in HSD17B13 and PNPLA3 were genotyped in 6,171 participants, including 1,03…

Characteristic of chronic plaque psoriasis patients treated with biologics in Italy during the COVID-19 pandemic. risk analysis from the PSO-BIO-COVI…

2021

Background The susceptibility of patients with chronic plaque psoriasis and the risks or benefits related to the use of biological therapies for COVID-19 are unknown. Few data about prevalence, clinical course and outcomes of COVID-19 among psoriatic patients were reported. The aims of this study were 1) to assess the prevalence and severity of COVID-19 in psoriatic patients treated with biologic agents during the first phase of the emergency (22 February to 22 April 2020) in Italy, and 2) to report the clinical outcomes of patients who have been exposed to individuals with confirmed SARS-CoV-2 infection. Methods Patients with moderate-to-severe chronic plaque psoriasis, aged ≥18 years and …
