Psychometric properties of the Depression Anxiety Stress Scales (DASS-21) in women with breast cancer.

Breast cancer impacts the psychological well-being of women, leaving them at risk of developing depression, anxiety, and other stress-related disorders. The Depression Anxiety Stress Scales (DASS-21) is a widely used measure, although empirical evidence regarding its psychometric properties in the breast cancer population is limited. The purpose of this study was to conduct an exhaustive analysis of the psychometric properties of the DASS-21 in a sample of Spanish women diagnosed with breast cancer.

Measurement invariance of the Facebook intrusion questionnaire across 25 countries.

Facebook is one of the most popular social networking sites. However, Facebook intrusion or addiction is a growing concern as it involves an excessive attachment to Facebook, which disrupts daily functioning. To date, few studies have examined whether cross-cultural differences in the measurement of Facebook addiction exist.

Ibuprofen and Other Arylpropionics: The Relevance in Immediate Hypersensitivity Drug Reactions.

Background: Ibuprofen, a non-steroidal anti-inflammatory drug (NSAID), is the most frequent medication to be involved in hypersensitivity drug reactions (HDRs). Other analgesic/anti-inflammatory drugs in the arylpropionic group are also relevant, albeit to a lesser extent. Ibuprofen is widely consumed by people of all ages, both on medical prescription and over the counter; moreover, it is an organic contaminant of surface waters and foods.

The Flourishing Scale: Psychometric Properties in Breast Cancer Patients.

Background/objective: Promoting well-being is a key goal of cancer care, and it needs to be assessed using appropriate instruments. Flourishing is considered part of psychological well-being and it is commonly assessed with the Flourishing Scale (FS). To our knowledge, no studies have analyzed the psychometric properties of the FS in breast cancer patients.

Ethanolysis of nitrogen mustards: A novel strategy for nitrogen mustard identification in environmental matrices by liquid chromatography-electrospray ionization-tandem mass spectrometry.

Rationale: Nitrogen mustards (NMs) are blistering chemical warfare agents. The ability to detect NMs in environmental samples is very important for obtaining forensic evidence. The most common analytical techniques for NM detection are gas chromatography-mass spectrometry, which detects NMs in their intact form but is disadvantaged by high limits of detection (LODs), and liquid chromatography-electrospray ionization-tandem mass spectrometry (LC/ESI-MS/MS) of their hydrolysis products, which do not provide robust evidence to support NM use.

Modulation of miR-29a and miR-29b Expression and Their Target Genes Related to Inflammation and Renal Fibrosis by an Oral Nutritional Supplement with Probiotics in Malnourished Hemodialysis Patients.

Malnutrition is prevalent in patients with chronic kidney disease (CKD), especially those on hemodialysis. Recently, our group described that a new oral nutritional supplement (ONS), specifically designed for malnourished (or at risk) hemodialysis patients with a "similar to the Mediterranean diet" pattern, improved caloric-protein intake, nutritional status and biomarkers of inflammation and oxidation. Our aim in this study was to evaluate whether the new ONS, associated with probiotics or not, may produce changes in miRNA's expression and its target genes in malnourished hemodialysis patients, compared to individualized diet recommendations.

Rapid and simple identification of trace amounts of sodium azide in beverages and bodily fluids followed by derivatization and liquid chromatography-electrospray ionization tandem mass spectrometry.

Rationale: Sodium azide (NaN ) is a toxic chemical agent to humans by ingestion and inhalation with a growing number of intentional exposures and accidental cases over the last few decades. Due to its low molecular weight and lack of any chromophore, its retention and detection by reverse-phase liquid chromatography-ultraviolet-mass spectrometry methods are a challenging task.

Methods: To be able to confirm azide exposure, we have developed a method to identify azide in both beverages and bodily fluids.

Life Satisfaction and Character Strengths in Women With Breast Cancer: Zest and Hope as Predictors.

Background: Empirical evidence shows that life satisfaction is positively related to character strengths, and although this association has been observed in different populations, it is scarce in breast cancer patients. This study analyzes the relationship between character strengths and life satisfaction in Spanish women diagnosed with breast cancer.

Methods: A sample of 117 women completed the Satisfaction with Life Scale (SWLS) and the Spanish version of the VIA Inventory of Strengths (VIA-IS).

Repeated measures ANOVA and adjusted -tests when sphericity is violated: which procedure is best?

Introduction: One-way repeated measures ANOVA requires sphericity. Research indicates that violation of this assumption has an important impact on Type I error. Although more advanced alternative procedures exist, most classical texts recommend the use of adjusted -tests, which are frequently employed because they are intuitive, easy to apply, and available in most statistical software.

Immunomodulatory Effects in Healthy Individuals Following a 4-Week Taoist Qigong Intervention: A Comparative Study.

BACKGROUND Qigong, an ancient health preservation technique forming part of Traditional Chinese Medicine, combines slow body movements, breathing, and meditation. While this meditative movement system has been reported to offer various physical and psychological benefits, studies on the Taoist school of qigong are sparse. This study, therefore, aimed to investigate the effects of Taoist qigong on white blood cells and other immune parameters in healthy individuals.

Validity Evidence for the Brief Self-Control Scale in the Spanish Adult Population: A Systematic Study.

The Brief Self-Control Scale (BSCS) has been widely studied across languages and populations. However, research examining the Spanish version is scant and limited to the adolescent population. Our aim here was to provide validity evidence for use of the BSCS with Spanish adults by analyzing and comparing the psychometric properties of different versions of the scale (13-item, 10-item, 9-item, 8-item, and 7-item).

Development and psychometric properties of the Stressors in Breast Cancer Scale.

Background: A diagnosis of breast cancer generates psychological stress, due not only to treatment and its side effects but also to the impact on different areas of the patient's daily life. Although there are instruments for measuring psychological stress in the cancer context, there is currently no tool for assessing stressors specific to breast cancer.

Aims: The aim of this study was to develop the Stressors in Breast Cancer Scale (SBCS).

Clavulanic Acid Is a Leading Culprit Beta-Lactam in Immediate Allergic Reactions to Penicillins.

Purpose: Clavulanate, a beta-lactam associated with amoxicillin, is frequently prescribed in patients at all ages. Recent data implicate amoxicillin-clavulanate in up to 80% of beta-lactam allergy cases. We assessed clavulanate's role in inducing allergic reactions to this combination treatment, with a focus on selective immediate reactions.

Effect on nutritional status and biomarkers of inflammation and oxidation of an oral nutritional supplement (with or without probiotics) in malnourished hemodialysis patients. A multicenter randomized clinical trial "Renacare Trial".

Background: Malnutrition in patients undergoing hemodialysis is frequent and associated with a reduction in muscular mass and strength, with an increment in biomarkers of inflammation and oxidation.

Materials And Methods: Randomized, multicenter, parallel-group trial in malnourished hemodialysis patients with three groups [(1) control (C) individualized diet, (2) oral nutritional supplement-ONS- + placebo-SU- PL-, and (3) ONS + probiotics-SU-PR]; the trial was open regarding the intake of ONS or individualized diet recommendations, but double-blind for the intake of probiotics. We obtained, at baseline and after 3 and 6 months, anthropometric measurements, handgrip strength, bioelectrical impedance analysis (BIA), dietary records, and routine biochemical parameters.

Non-normal Data in Repeated Measures ANOVA: Impact on Type I Error and Power.

Background: Repeated measures designs are commonly used in health and social sciences research. Although there are other, more advanced, statistical analyses, the F-statistic of repeated measures analysis of variance (RM-ANOVA) remains the most widely used procedure for analyzing differences in means. The impact of the violation of normality has been extensively studied for between-subjects ANOVA, but this is not the case for RM-ANOVA.

Prevalence of Child Contact Sexual Abuse in the Spanish Region of Andalusia.

The aim of this study was to analyze the prevalence and characteristics of child sexual abuse (CSA) in Andalusia, Spain's most populated region. A sample of 817 adults (281 male; age = 34.7;  = 13.

Sensitisation to Pollen Allergens in Children and Adolescents of Different Ancestry Born and Living in the Same Area.

Background: Allergy can start at early ages, with genetic and environmental factors contributing to its development.

Aim: The study aimed to describe the pattern of sensitisation and allergy in children and adolescents of Spanish versus Moroccan ancestry but born in the same rural area of Spain.

Methods: Participants were children and adolescents (3-19 years) of Spanish or Moroccan descent, born in Blanca, Murcia (Spain).

Psychometric properties of the perceived stress scale (pss-10) with breast cancer patients.

Breast cancer diagnosis is one of the most difficult events that a woman can experience during her life and it usually produces high levels of stress. Global measures of perceived stress are useful for screening and for comparing stress levels between cancer patients and other clinical and nonclinical populations. One such instrument that is widely used is the Perceived Stress Scale (pss-10), but its psychometric properties have scarcely been analysed with breast cancer patients.

Assessing Satisfaction With Online Courses: Spanish Version of the Learner Satisfaction Survey.

The aim of this study was to develop a Spanish version of the Learner Satisfaction Survey (LSS-S) and to analyze its psychometric properties. The questionnaire was administered to a sample of 1,194 university students. Validity evidence based on the instrument's internal structure and on relationships with other variables (personality and motivation) were analyzed.

Enhancing students' well-being with a unified approach based on contextual behavioural science: A randomised experimental school-based intervention.

A new generation of interventions has begun to move towards principles of acceptance that deal with the context and function of psychological events. The aim of this paper is to analyse the effectiveness of a brief contextual behavioural intervention to improve the psychological well-being of secondary school students. This intervention represents a unified model with key processes based on contextual behavioural science, including Acceptance and Commitment Therapy (ACT) and Functional Analytic Psychotherapy (FAP).
