Abstract Introduction There are several conditions that may cause chronic venous disease (CVD). It is not known whether the aetiology of CVD can predict disease severity and quality of life (QoL). ...Our objective is that the severity and QoL of patients with CVD secondary to DVT is different from those without prior DVT. Material and methods We compare patients with CVD caused by DVT (n = 125) and patients with non-DVT CVD (n = 1435) with respect to disease severity (CEAP and Venous Clinical Severity Score-VCSS) and quality of life (Health Survey Short-Form-SF12 y Chronic Lower Limb Venous Insufficiency Questionnaire-CIVIQ20). Results Regarding to non-thrombotic CVD, patients with CVD due to DVT showed more severe disease C6 grade (14.4% vs 3.6%) (p < 0.05); score VCSS (1,33 ± 0,65 vs 0,84 ± 0,49) (p < 0.05) and poorer QoL global score CIVIQ-20 (57,84 ± 15,57 vs 65,75 ± 14,07) (p < 0.05); global score SF-12 (45,98 ± 18,79 vs 57,79 ± 19,64) (p < 0.05).. These differences remained statistical significant in all parameters – attributed measured at each severity score and QoL questionnaires. Conclusion A history of DVT leads to worse clinical severity and quality of life in CVD patients. These data support even more the need to implement programs to prevent DVT and/or its evolutionary consequences.
Roura, Á., González, Á. F., Pascual, S., and Guerra, Á. 2010. A molecular approach to identifying the prey of cephalopod paralarvae. – ICES Journal of Marine Science, 67: 1408–1412. A molecular ...method was developed to detect Artemia franciscana within Octopus vulgaris paralarvae, as a first step towards understanding the diet of octopus during this life stage. Wild eggs were collected from a spawning female in the Ría de Vigo (northwestern Spain) in late summer, and brought to the laboratory. After hatching, paralarvae were reared in 30 l rectangular tanks with an open seawater filtered system. Paralarvae were fed Artemia, then immediately fixed in 80% ethanol and preserved at −20°C. Primers specific to A. franciscana were designed for the gene cytochrome c oxidase subunit I. A nested polymerase chain reaction was necessary to detect A. franciscana within octopus paralarvae. This molecular method provides a new framework for resolving the diet of cephalopod paralarvae in the wild, essential for ecological understanding and increasing survival rates in aquaculture.
The processes involved in the assembly of zinc acetate dihydrate {Zn(CH3COO)2·2H2O} and ethanolamine (H2NCH2CH2OH), with or without 2-methoxyethanol as solvent, have been analysed by infrared ...spectra, mass spectrometry, nuclear magnetic resonance, powder X-ray diffraction and computational studies. Thermal evolution of the mixtures was characterized by thermoanalytical and structural techniques (thermogravimetry, differential thermal analysis, differential scanning calorimetry, X-ray diffraction and X-Ray photoelectron spectroscopy). Computational studies together with experiments served to thoroughly describe the precursor and its decomposition. The thermal decomposition of the mixture and its transformation into crystalline ZnO take place in a temperature range between 50 and 450 °C through different processes. With solvent, the processes need temperatures 90 oC higher with respect to the mixture without solvent, and ZnO arises at 250 ºC.

Human papillomavirus (HPV) is a sexually transmitted infection that may lead to development of precancerous and cancerous lesions of the cervix. The aim of the current study was to investigate ...socio-demographic, lifestyle, and medical factors for potential associations with cervical HPV infection in women undergoing cervical cancer screening in Spain.
The CLEOPATRE Spain study enrolled 3 261 women aged 18-65 years attending cervical cancer screening across the 17 Autonomous Communities. Liquid-based cervical samples underwent cytological examination and HPV testing. HPV positivity was determined using the Hybrid Capture II assay, and HPV genotyping was conducted using the INNO-LiPA HPV Genotyping Extra assay. Multivariate logistic regression was used to identify putative risk factors for HPV infection.
A lifetime number of two or more sexual partners, young age (18-25 years), a history of genital warts, and unmarried status were the strongest independent risk factors for HPV infection of any type. Living in an urban community, country of birth other than Spain, low level of education, and current smoking status were also independent risk factors for HPV infection. A weak inverse association between condom use and HPV infection was observed. Unlike monogamous women, women with two or more lifetime sexual partners showed a lower risk of infection if their current partner was circumcised (P for interaction, 0.005) and a higher risk of infection if they were current smokers (P for interaction, 0.01).
This is the first large-scale, country-wide study exploring risk factors for cervical HPV infection in Spain. The data strongly indicate that variables related to sexual behavior are the main risk factors for HPV infection. In addition, in non-monogamous women, circumcision of the partner is associated with a reduced risk and smoking with an increased risk of HPV infection.

Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome. The characteristics and in-hospital clinical course of patients with SCAD in Spain remain unknown.
We ...present data from consecutive patients included in the national prospective SCAD registry. Angiographic analysis was performed in a centralized core laboratory.
Between June 2015 and April 2019, we included 318 patients with SCAD (358 lesions) from 31 centers. Median age was 53 years, and 88% were women. The most frequent presentation was non–ST-segment elevation acute myocardial infarction (53%). The most frequently involved artery was the left anterior descending coronary artery (44%), predominantly affecting the distal segments (39%) and secondary branches (54%). Most lesions (62%) appeared on angiography as intramural hematoma, without double lumen. Conservative management was selected as the initial approach in most patients (78%). During the index admission, 6% of patients had a major adverse event and 4 patients (1.3%) died. Independent predictors of adverse events were initial management with percutaneous coronary intervention (OR, 5.97; P=.004) and angiographic presentation as intramural hematoma (OR, 4.96; P=.028).
In Spain, SCAD affects mainly middle-aged women. In most patients, the initial management strategy was conservative with excellent in-hospital survival. Initial management with percutaneous coronary intervention and angiographic presentation as intramural hematoma were related to the presence of in-hospital adverse events.

La disección coronaria espontánea (DCE) es una causa infrecuente de síndrome coronario agudo. Las características y la evolución hospitalaria de los pacientes con DCE en nuestro país no son conocidas.
Se desarrolló un registro nacional prospectivo de pacientes con DCE. Se llevó a cabo un análisis centralizado de los estudios de coronariografía.
Entre junio de 2015 y abril de 2019, se incluyó a 318 pacientes con DCE (358 lesiones) procedentes de 31 centros. La mediana de edad fue de 53 años (el 88% mujeres). La presentación más frecuente fue como infarto sin elevación del segmento ST (53%). La arteria más frecuentemente implicada fue la descendente anterior (44%), con afección predominante de los segmentos distales (39%) y las ramas secundarias (54%). La mayor parte de las lesiones (62%) se presentaron en angiografía como hematoma intramural sin doble luz. En una mayoría de casos (78%) se optó por el tratamiento conservador. Durante el ingreso, un 6% de los pacientes sufrió algún evento adverso y 4 pacientes (1,3%) fallecieron. El tratamiento inicial con intervención coronaria percutánea (OR=5,97; p=0,004) y la presentación angiográfica como hematoma intramural (OR=4,96; p=0,028) fueron predictores independientes de eventos adversos durante el ingreso.
La DCE en nuestro país afecta principalmente a mujeres de mediana edad. La estrategia inicial fue en su mayoría conservadora, con una excelente supervivencia hospitalaria. La presentación angiográfica como hematoma intramural y el tratamiento inicial con intervención coronaria percutánea se relacionaron con que se produjeran eventos adversos hospitalarios.
