Editorial: Best Practice Approaches for Mixed Methods Research in Psychological Science

The aim of this Research Topic is to present a selection of studies whose methodological approaches include, as a central element, aspects related to the Gordian knot of mixed methods, that also incorporate secondary -but no less important- elements such as dataset transformation, analytical techniques and data integration, as well as studies in which systematic observation is used as a mixed method in itself. The Research Topic has promoted a transparent presentation of the mixed approach used to develop the conceptual, methodological or application-related contribution of each article. This transparency will enable other researchers to critically appraise and replicate the methods used. The 32 articles that make up the Research Topic Best Practice Approaches for Mixed Methods Research in Psychological Science, with contribution from 121 authors, are organized from a substantive point of view in different criteria, although each of the published articles could have been 'classified' from several points of view. It is important to highlight the contributions made in the articles published in this Research Topic from the methodological criteria, given the conceptual amplitude of the mixed methods topic and its repercussions in applied studies

Structure versus function: correlation between outer retinal and choroidal thicknesses measured by swept-source OCT with multifocal electroretinography and visual acuity

Background: To correlate retina-choroidal anatomy as assessed via swept-source OCT (SS-OCT) with retinal function as determined by best-corrected visual acuity (BCVA) and multifocal electroretinogram (mfERG). Methods: Thirty-three eyes from 33 patients including 16 with neovascular AMD (nvAMD) and 17 controls were included. Patients were included in the present study after a complete ophthalmologic examination, including BCVA, slit-lamp study, intraocular pressure measurement, dilated fundus examination after tropicamide instillation, SD-OCT, SS-OCT, fundus photographs and mfERG. Age, sex, BCVA, number of anti-VEGF intravitreal injections in the nvAMD group, were recollected. Outer retinal and choroidal thickness were determined at the fovea and 500 μm temporal, superior, nasal and inferior. First-order response from mfERG was collected. P1 amplitude was recorded in R1, R2 and the average of R1 + R2. The measurements recollected from the SS-OCT, mfERG and BCVA were compared. Results: Better BCVA was found with thicker outer retina foveal thickness (r = 0.349; P = 0.047), with thicker subfoveal choroidal thickness (r = 0.443; P = 0.010), and with higher amplitude in P1 at R1 (r = 0.346; P = 0.037). Outer retina foveal thickness did not correlate with P1 amplitude at R1 (r = 0.072; P = 0.692), R2 (r = 0.265; P = 0.137) either with the average P1 amplitude at R1 + R2 (r = 0.253; P = 0.156). A thicker subfoveal choroidal thickness was related with higher amplitude in P1 at R1 (r = 0.383; P = 0.028), R2 (r = 0.409; P = 0.018) and the average of R1 + R2 (r = 0.419; P = 0.015). Conclusions: Choroidal thickness demonstrated a positive correlation with retinal function in the sample studied, so a thicker choroid is related to a better retinal function measured with mfERG and BCVA

Vaccine-induced modulation of gene expression in turbot peritoneal cells. A microarray approach

This is the accepted manuscript of the following article: Fontenla, F., Blanco-Abad, V., Pardo, B.G., Folgueira, I., Noia, M., Gómez-Tato, A., Martínez, P., Leiro, J.M. & Lamas J. (2016). Vaccine-induced modulation of gene expression in turbot peritoneal cells. A microarray approach. Molecular Immunology, 75, 188-99. doi: 0.1016/j.molimm.2016.06.001We used a microarray approach to examine changes in gene expression in turbot peritoneal cells after injection of the fish with vaccines containing the ciliate parasite Philasterides dicentrarchi as antigen and one of the following adjuvants: chitosan- PVMMA microspheres, Freund´s complete adjuvant, aluminium hydroxide gel or Matrix-Q (Isconova, Sweden). We identified 374 genes that were differentially expressed in all groups of fish. Forty-two genes related to tight junctions and focal adhesions and/or actin cytoskeleton were differentially expressed in free peritoneal cells. The profound changes in gene expression related to cell adherence and cytoskeleton may be associated with cell migration and also with the formation of cellvaccine masses and their attachment to the peritoneal wall. Thirty-five genes related to apoptosis were differentially expressed. Although most of the proteins coded by these genes have a proapoptotic effect, others are antiapoptotic, indicating that both types of signals occur in peritoneal leukocytes of vaccinated fish. Interestingly, many of the genes related to lymphocytes and lymphocyte activity were downregulated in the groups injected with vaccine. We also observed decreased expression of genes related to antigen presentation, suggesting that macrophages (which were abundant in the peritoneal cavity after vaccination) did not express these during the early inflammatory response in the peritoneal cavity. Finally, several genes that participate in the inflammatory response were differentially expressed, and most participated in resolution of inflammation, indicating that an M2 macrophage response is generated in the peritoneal cavity of fish one day post vaccinationThis work was financially supported by the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 634429 (PARAFISHCONTROL), by the Ministerio de Economía y Competitividad (Spain) under grant agreement AGL2014-57125-R and by grant GPC2014/069 from the Xunta de Galicia (Spain)S

Carbon integral honeycomb monoliths as support of copper catalysts in the Kharasch–Sosnovsky oxidation of cyclohexene

Carbon integral honeycomb monoliths prepared from a natural coal were employed as support of copper catalysts for organic synthetic purposes. In particular good to excellent yields (60–100% as function of the carboxylic acid employed) were obtained in the preparation of allylic esters by the Kharasch–Sosnovsky oxidation of cyclohexene. Different characterization techniques such as chemical analysis by Inductively Coupled Plasma Spectroscopy, nitrogen physisorption, X-ray Diffraction with Rietveld analysis, X-ray Photoelectron and Raman Spectroscopies, Temperature-Programmed Reduction and Scanning Electron Microscopy allowed finding that key parameters such as textural properties, degree of copper precursor decomposition and active phase homogeneity and dispersion can be modulated as function of a simple synthetic variable: the method used to dry the monoliths after impregnation with the metal precursor, either conventional or using microwaves. The results obtained allow understanding the key role of the nature and chemical surrounding (O2 anions or OH groups) of Cu2+ ions in the catalytic activity in the reaction investigated as well as the operating deactivation mechanisms. The use of the structured catalysts here proposed also opens up an interesting alternative to homogeneous catalysis in the field of organic synthesis

Liquid biopsy: a non-invasive approach for Hodgkin lymphoma genotyping

The Hodgkin lymphoma (HL) genomic landscape is hardly known due to the scarcity of tumour cells in the tissue. Liquid biopsy employing circulating tumour DNA (ctDNA) can emerge as an alternative tool for non-invasive genotyping. By using a custom next generation sequencing (NGS) panel in combination with unique molecule identifiers, we aimed to identify somatic variants in the ctDNA of 60 HL at diagnosis. A total of 277 variants were detected in 36 of the 49 samples (73·5%) with a good quality ctDNA sample. The median number of variants detected per patient was five (range 1–23) with a median variant allele frequency of 4·2% (0·84–28%). Genotyping revealed somatic variants in the following genes: SOCS1 (28%), IGLL5 (26%), TNFAIP3 (23%), GNA13 (23%), STAT6 (21%) and B2M (19%). Moreover, several poor prognosis features (high LDH, low serum albumin, B-symptoms, IPI ≥ 3 or at an advanced stage) were related to significantly higher amounts of ctDNA. Variant detection in ctDNA by NGS is a feasible approach to depict the genetic features of HL patients at diagnosis. Our data favour the implementation of liquid biopsy genotyping for the routine evaluation of HL patients.This work was partially supported by the Instituto de Salud Carlos III (ISCIII), Spanish Ministry of Economy and Competitiveness CIBERONC-CB16/12/00233, and “Una manera de hacer Europa” (Innocampus; CEI-2010-1-0010)”, the Health Council of the Junta de Castilla y León (GRS2037/A/19) (GRS1845/A/18) and private Gilead (GLD/18/00063).
