Sex-comparative study of gambling disorder regarding alexithymia and symptoms of depression, anxiety and hostility
Alexithymia and psychological symptomatology have been closely associated with gambling disorder (GD). However, sex differences remain underexplored. This study aims, firstly, to explore the differences between groups (GD and no-GD) and sexes (women vs. men) in alexithymia and psychological symptomatology (depression, anxiety and hostility). Secondly, the relationship between alexithymia and psychological symptomatology was analysed by gambling and sex groups. Thirdly, it examines the moderation role of sex and gambling in the relationship between alexithymia and each psychological symptom. The sample was composed of 80 people with GD diagnosis and 80 without GD (40 women and 40 men in each group). The results showed that alexithymia is positively related to depression, anxiety and hostility, with significantly higher scores in people with GD. Moderation analyses showed a threefold interaction, in which higher alexithymia was related to higher depression for men with GD but not for GD-women. However, in women with GD, depression levels are higher than in people without GD and tend to be more stable over time, despite the lack of effect of alexithymia. These results provide evidence indicating that dysfunctional psychological symptomatology affects people with GD to a greater extent than people without GD, but also that the aetiology and effect of underlying vulnerability factors on gambling is different according to sex. The need of prevention and treatment programmes that consider different psychological aspects depending on sex is reinforced. •People with GD obtained higher scores in alexithymia, depressión, anxiety and hostility.•The most significant differences between the GD and non-GD group were in symptoms of depression.•Women (with and without GD) presented lower standard deviation in all psychological symptomatology, but men had higher scores.•The strongest relationship between alexithymia and depression was found in men with GD.•Alexithymia did not affect depression levels in women with GD.
Analysis of operational parameters in acid and base production using an electrodialysis with bipolar membranes pilot plant
In agreement with the Water Framework Directive, Circular Economy and European Union (EU) Green Deal packages, the EU-funded WATER-MINING project aims to validate next-generation water resource solutions at the pre-commercial demonstration scale in order to provide water management and recovery of valuable materials from alternative sources. In the framework of the WATER-MINING project, desalination brines from the Lampedusa (Italy) seawater reverse osmosis (SWRO) plant will be used to produce freshwater and recover valuable salts by integrating different technologies. In particular, electrodialysis with bipolar membranes (EDBM) will be used to produce chemicals (NaOH and HCl). A novel EDBM pilot plant (6.4 m2, FuMa-Tech) has been installed and operated. The performance of EDBM for single pass under different flowrates (2–8 L·min−1) for acid, base and saline channels, and two current densities (200 and 400 A·m−2), has been analyzed in terms of specific energy consumption (SEC) and current efficiency (CE). Results showed that by increasing the flowrates, generation of HCl and NaOH slightly increased. For example, ΔOH− shifted from 0.76 to 0.79 mol·min−1 when the flowrate increased from 2 to 7.5 L·min−1 at 200 A·m−2. Moreover, SEC decreased (1.18–1.05 kWh·kg−1) while CE increased (87.0–93.4%), achieving minimum (1.02 kWh·kg−1) and maximum (99.4%) values, respectively, at 6 L·min−1.
Plasma concentrations of IL-6, MIP-1β, IP-10, and PTX-3 as predictors of the immunological response to antiretroviral treatment in people with HIV
Despite effective antiretroviral therapy (ART), 15-30% of people with HIV experience poor CD4 + T-cell recovery, termed immunologic non-responders (INR). This study aims to evaluate whether pre-ART plasma levels of interleukin-6 (IL-6), interferon gamma-induced protein-10 (IP-10), macrophage inflammatory protein-1-β (MIP-1β), and/or pentraxin-3 (PTX-3) could predict subsequent immunologic recovery. Seventy-four participants were enrolled and classified as INR and immunologic responders (IR) based on CD4 + /CD8 + ratio increase over 24 months after starting ART. The results showed no significant differences in cytokine levels between INR and IR. Therefore, IL-6, IP-10, MIP-1β, and PTX-3 were unsuitable as predictive markers of poor immune recovery.
Differential Impact of Parental Practices and Parental Emotional Clarity on Child Symptoms in Single-Child vs. Multiple-Child Divorced Families
Objective: The main objective of this study was to analyze the differences in parental emotional clarity and parental practices among families with a single child and families with more than one child, and their relationship with the children’s internalizing and externalizing symptomatology, specifically, anxiety–depression and aggressive behavior in a conflictive divorce context. Methods: The participants were 247 Spanish divorced parents. In total, 62% of the participants reported being the parents of one child and 38% of two children. All participants answered questionnaires that measured the variables investigated in this study. Results: The results supported the working hypothesis that families with more than one child present with less emotional clarity, which, concatenated with critical and rigid parental guidelines, is associated with children’s greater presence of anxious–depressive and aggressive symptoms. Conclusions: Families with more than one child have less positive parental guidelines and so their children express more symptoms.
Long-term effects on immunological, inflammatory markers, and HIV-1 reservoir after switching to a two-drug versus maintaining a three-drug regimen based on integrase inhibitors
To compare the long-term effects on immune parameters, inflammation, and HIV-1 reservoir after switching to a two-drug (2DR) versus maintaining an integrase inhibitor (InSTI)-based three-drug regimen (3DR). Cross-sectional study in which HIV-1 treatment-naïve people started and maintained an InSTI-based 3DR or, at different times, switched to 2DR (dolutegravir or darunavir/cobicistat + lamivudine). CD4 and CD8 T-cell activation and exhaustion, plasma concentrations of hs-CRP, D-dimer, P-selectin, IL-1β, IL-6, TNF-α, IFN-γ, IP-10, sTNFR-I/II, MIP-1α/β, I-FABP, LBP, sCD14, sCD163, MCP-1, and cellular-associated HIV-1-DNA and -RNA were quantified by flow cytometry, different immunoassays, and droplet digital PCR, respectively. The U de Mann-Whitney test evaluated differences between 3DR and 2DR. Immune recovery was evaluated using a general linear model for repeated measures adjusted for different co-variables. Fifty participants per group were included. The median time on 3DR was 82 months for the 3DR group and 30 months for the 2DR group, after which it switched to 2DR for a median of 57 months. We did not find differences between both groups in any of the parameters analyzed. Specifically, some values in 3DR and 2DR were hs-CRP, 0.92 mg/L (0.45-2.23) vs. 1.23 (0.61-2.38); D-dimer, 190.0 µg/L (150.0-370.0) vs. 190.0 (150.0-397.5); IL-6, 2.8 pg/mL (1.3-5.3) vs. 3.2 (2.1-4.7); sCD14, 4.5 ng/mL (3.3-6.2) vs. 5.0 (3.6-6.1), respectively, all p ≥ 0.399. In the long term, switching to 2DR does not negatively affect immunologic parameters, inflammatory markers, or HIV-1 reservoir. identifier NCT04076423.
The Impact of Insecure Attachment on Emotional Dependence on a Partner: The Mediating Role of Negative Emotional Rejection
Previous evidence has demonstrated a relationship between insecure attachment and the development of emotional dependence towards an individual’s partner. However, the possibility that this relationship may be indirect and mediated by individual factors such as difficulties in emotional regulation has not previously been explored. Consequently, the objectives of the present study were to analyze the (i) differences in emotional dependence on an individual’s partner and difficulties in emotional regulation capacity according to secure, preoccupied or dismissing attachment style and (ii) mediating role of difficulties in emotional regulation in the relationship between both insecure attachment styles and emotional dependence on an individual’s partner. The sample comprised 741 participants ranging in age from 18 to 30 years (M = 21.32, SD = 2.93). The mediations were tested with linear regressions with the macro PROCESS v4.0. The results showed that emotional dependence on a partner and difficulties in emotional regulation were greater among individuals who had developed a dismissing attachment compared those with secure or preoccupied attachment. Likewise, the mediation model confirmed the mediating role of difficulties in the capacity for emotional regulation in the relationship between dismissing attachment and emotional dependence, with rejection of negative or discomfort-generating emotions predominating. The findings provide preliminary evidence that rejection of negative emotional experiences may play an important role in the relationship between insecure dismissing attachment style and emotional dependence on an individual’s partner. Consequently, it is recommended that emotional dependence intervention programs include of the management of intolerance to negative emotions.
La implantación del culto imperial de la provincia en Hispania
The aim of this study is to show how the Imperial Cult was introduced and organised in provincial Hispania, and examines the collaboration with the Romanised native elites who came from Lusitania, Baetica and Hispania Citerior. This book draws upon literary, numismatic, archaeological and epigraphic sources. The epigraphy found in Lusitania is especially important because it is the only one of the Hispanic provinces where there is evidence of flamines provinciae officiating before the Flavian period, even as early as under Tiberius.
The Off-Label Use of Antineoplastics in Oncology Is Limited But Has Notable Scientific Support in a University Hospital Setting
The off-label (OL) use of antineoplastic drugs for the treatment of various types of tumors in patients of different disease stages is becoming a common occurrence. The objective of this study was to analyze these patterns by quantification and characterization of the OL use of antineoplastic drugs and their level of scientific evidence in a medium/high-complexity Spanish general university hospital. All oncology patients who underwent OL treatment with one or several antineoplastics during the 10 years from 2002 to 2012 were retrospectively selected. The use of these drugs was considered OL if they were used for indications, stages, lines of treatment, or chemotherapy schemes not reflected in the summary of product characteristics published by the European Medicines Agency at the time of prescription. To calculate the prevalence of patients who received one or more OL treatments during the study period, all patients whose primary or secondary diagnosis had been coded with the diagnoses included in the study were selected through the minimum basic data set (MBDS). This database was cross-referenced with that of the Farmatools program (Dominion ), which collects information on all patients receiving chemotherapy to obtain the total number of patients who received chemotherapy in the hospital during this period. In total, 684 patients and 866 OL treatments were included. The prevalence of patients undergoing OL treatment with antineoplastics was 6%. OL treatments were used mainly for breast, gynecological, lung, and gastric tumors. The most often-used antineoplastic was paclitaxel, followed by gemcitabine, carboplatin, vinorelbine, and capecitabine, which were used mainly in monotherapy and with palliative intent. A total of 56.1% of the OL schemes used had a level of evidence of 2A according to the National Comprehensive Cancer Network, and 55.3% had a level of evidence of 2B according to Micromedex . The OL use of antineoplastics in oncology patients is limited; their use is mainly focused in a small group of tumors and at advanced stages of disease. OL use of antineoplastics occurs under palliative therapeutic strategies with a limited number of drugs, preferably off-patent drugs. In addition, these OL treatments have high levels of clinical evidence.
Early-Life Exposure to Formaldehyde through Clothing
Clothes contain a wide range of chemicals, some of them potentially hazardous. Recently, there has been a growing interest in eco-friendly clothing, including the use of organic cotton. However, the process of eco-friendly fabric production does not exclude the use of toxic substances, such as formaldehyde, a known human carcinogen. The present investigation was aimed at determining the presence of formaldehyde in eco-friendly and conventional clothing of pregnant women, babies, and toddlers from the Catalan (Spain) market. The potential effects of washing were also investigated by comparing the reduction of formaldehyde in unwashed and washed clothing. Formaldehyde was detected in 20% of samples, with a mean level of 8.96 mg/kg. Formaldehyde levels were surprisingly higher in eco-friendly than in regular garments (10.4 vs. 8.23 mg/kg). However, these differences were only significant (p < 0.05) for bras (11.6 vs. 7.46 mg/kg) and panties (27.1 vs. 6.38 mg/kg) of pregnant women. Dermal exposure and health risks were assessed for three vulnerable population groups: pregnant women, babies, and toddlers. In general, exposure was higher in babies (up to 1.11 × 10−3 mg/kg/day) than in other groups (2.58 × 10−4 and 4.50 × 10−3 mg/kg/day in pregnant women and toddlers, respectively). However, both non-carcinogenic and carcinogenic risks were below the safety limits (<1 and <10−5, respectively) according to national regulations. Notwithstanding, although formaldehyde levels were below the legal limits (<75 mg/kg) and health risks were within acceptable ranges, clothing may contain other toxic substances in addition to formaldehyde, thus increasing the risks. Finally, since no formaldehyde was detected in washed textile samples, a safe and simple practice for the consumers is to wash clothing before the first use.
