Nomophobia in university students during COVID-19 outbreak: a cross-sectional study.

Introduction: Currently, access to the Internet through smartphones has led to their functions going beyond purely communicative ones, allowing the management of massive, instantaneous, and easily accessible information. This research analyzed the differences in smartphone use and the prevalence of nomophobia, mainly according to gender and university degree of Health Sciences students at the University of Zaragoza during the COVID-19 confinement in Spain.

Methods: A descriptive cross-sectional study was carried out on a sample of 318 first and second-grade students, who completed an online questionnaire sent to their institutional email, which included sociodemographic questions, other questions about smartphone use, and the Nomophobia Questionnaire (NMP-Q) scale.

Impact of the -1438G>a polymorphism in the serotonin 2A receptor gene on anthropometric profile and obesity risk: a case-control study in a Spanish Mediterranean population.

Research into the genetic factors that regulate food intake is arousing great interest. The polymorphism -1438G>A in the serotonin 2A receptor or 5-hydroxytriptamine (5-HT) type 2A receptor (5-HTR2A) gene has been associated with alterations in food intake such as anorexia and bulimia. However, its association with obesity has not been studied to the same extent.

[SLC7A9 gene variation: impact of 13 frequent mutations in the etiology of cystinuria in a Spanish Mediterranean population].

Background And Objective: The aim of this study was to investigate the presence of the most prevalent mutation in the SLC7A9 gene in families of the Mediterranean Spanish population and their association with clinical phenotypes.

Patients And Method: Twenty cystinuria families were studied (6 type I, 12 non type I, and 2 unknown type), including 48 cystinuria patients and 44 relatives. DNA was isolated and molecular analysis of 13 variations (P52L, N58_G79del22, G63R, G105R, T123M, V170M, A182T, V188M, c.

[Factor V Leiden (G1691A) and prothrombin-G20210A alleles among patients with deep venous thrombosis and in the general population from Spain].

Background: Factor V leiden and the -G20210A variant of prothrombin gene are associated to a higher risk of deep venous thrombosis.

Aim: To assess the frequency of factor V Leiden (G1691A) and prothrombin -G20210A alleles in patients with deep venous thrombosis (DVT) and in the general population from Spain.

Material And Methods: Factor V Leiden (g1691a) and prothrombin-g20210a alleles were genotyped in 493 individuals from the Spanish general populations and in 131 patients with DVT.

Associations of LPL and APOC3 gene polymorphisms on plasma lipids in a Mediterranean population: interaction with tobacco smoking and the APOE locus.

We conducted a cross-sectional study in a Spanish population (n = 1,029) to investigate associations between the LPL and APOC3 gene loci (LPL-HindIII, LPL-S447X, and APOC3-SstI) and plasma lipid levels and their interaction with APOE polymorphisms and smoking. Carriers of the H(-) or the X447 allele had higher levels of HDL cholesterol (HDL-C), and lower levels of TG, after adjustment for age, body mass index, alcohol, smoking, exercise, and education (P < 0.01).
