(American Psychological Association, 2023) Del Cacho Tena, Ana María; Merced, Kritzia; Perrin, Paul B.; Arango Lasprilla, Juan Carlos; Olabarrieta Landa, Laiene; Rivera, Diego; Ciencias de la Salud; Osasun Zientziak
Objective: Naming is commonly impaired in people with neurodegenerative diseases and brain injury, and as a result, its accurate assessment is essential. The aim of this study was to provide normative data for the 15-item Spanish version of the Boston Naming Test (BNT) for an adult population from eight Latin American countries/regions. Method: The total sample consisted of 2,828 participants from Argentina, Chile, Cuba, El Salvador, Mexico, Honduras, Paraguay, and Puerto Rico. Multiple regressions were used to generate normative data following a four-step process. Results: Regression models showed a linear effect of age on the 15-item BNT total score for Argentina, Chile, Mexico, and Puerto Rico. In contrast, Paraguay showed a quadratic age effect. Almost all countries showed a positive linear effect of education, except Cuba which had a quadratic effect. Sex was a significant predictor in Argentina, Chile, Cuba, and Mexico, where in women scored lower than men. Conclusions: This study generates normative data for the 15-item Spanish version of the BNT and offers a free open-source calculator that will assist in the efficacious use of this neuropsychological test in clinical practice and research.

20-Year trajectories of six psychopathological dimensions in patients with first-episode psychosis: could they be predicted?
(Elsevier, 2024) Cuesta, Manuel J.; Gil Berrozpe, Gustavo José; Sánchez Torres, Ana María; Moreno-Izco, Lucía; García de Jalón, Elena; Peralta Martín, Víctor; SEGPEPs Group; Ciencias de la Salud; Osasun Zientziak
Patients with first-episode psychoses (FEP) exhibit heterogeneity in clinical manifestations and outcomes. This study investigated the long-term trajectories of six key psychopathological dimensions (reality-distortion, negative, disorganization, catatonia, mania and depression) in patients diagnosed with FEP. A total of 243 patients were followed up for 20 years and the trajectories of the dimensions were analysed using growth mixture modelling. These dimensions showed varied course patterns, ranging from two to five trajectories. Additionally, the study examined the predictive value of different factors in differentiating between the long-term trajectories. The exposome risk score showed that familial load, distal and intermediate risk factors, acute psychosocial stressors and acute onset were significant predictors for differentiating between long-term psychopathological trajectories. In contrast, polygenic risk score, duration of untreated psychosis and duration of untreated illness demonstrated little or no predictive value. The findings highlight the importance of conducting a multidimensional assessment not only at FEP but also during follow-up to customize the effectiveness of interventions. Furthermore, the results emphasize the relevance of assessing premorbid predictors from the onset of illness. This may enable the identification of FEP patients at high-risk of poor long-term outcomes who would benefit from targeted prevention programs on specific psychopathological dimensions.

Abordando las necesidades de los largos supervivientes de cáncer y sus familias: una reflexión comunitaria
(SEAPA, 2024-12-01) García Vivar, Cristina; Ciencias de la Salud; Osasun Zientziak
En Europa, más de 23 millones de personas han tenido un diagnóstico de cáncer. Según el estudio EUROCARE 6, que analiza la prevalencia del cáncer en Europa, se ha identificado que los largos supervivientes de cáncer, aquellos que han superado los cinco años tras su diagnóstico, constituyen una proporción creciente y predominante de la población de supervivientes. Esta tendencia se espera que continúe en aumento, generando preocupación sobre la capacidad de los sistemas de salud para satisfacer las necesidades específicas de este grupo poblacional.

Absence of nuclear p16 is a diagnostic and independent prognostic biomarker in squamous cell carcinoma of the cervix
(MDPI, 2020) Mendaza Lainez, Saioa; Fernández Irigoyen, Joaquín; Santamaría Martínez, Enrique; Zudaire, Tamara; Guarch, Rosa; Guerrero Setas, David; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
The tumor-suppressor protein p16 is paradoxically overexpressed in cervical cancer (CC). Despite its potential as a biomarker, its clinical value and the reasons for its failure in tumor suppression remain unclear. Our purpose was to determine p16 clinical and biological significance in CC. p16 expression pattern was examined by immunohistochemistry in 78 CC cases (high-grade squamous intraepithelial lesions (HSILs) and squamous cell carcinomas of the cervix –SCCCs). CC cell proliferation and invasion were monitored by real-time cell analysis and Transwell® invasion assay, respectively. Cytoplasmic p16 interactors were identified from immunoprecipitated extracts by liquid chromatography-tandem mass spectrometry, and colocalization was confirmed by double-immunofluorescence. We observed that SCCCs showed significantly more cytoplasmic than nuclear p16 expression than HSILs. Importantly, nuclear p16 absence significantly predicted poor outcome in SCCC patients irrespective of other clinical parameters. Moreover, we demonstrated that cytoplasmic p16 interacted with CDK4 and other unreported proteins, such as BANF1, AKAP8 and AGTRAP, which could sequester p16 to avoid nuclear translocation, and then, impair its anti-tumor function. Our results suggest that the absence of nuclear p16 could be a diagnostic biomarker between HSIL and SCCC, and an independent prognostic biomarker in SCCC; and explain why p16 overexpression fails to stop CC growth.

Accelerated bacterial identification with MALDI-TOF MS leads to fewer diagnostic tests and cost savings
(MDPI, 2024-12-02) Uzuriaga, Miriam; Guillén Grima, Francisco; Rua, Marta; Leiva, José; Yuste, José R.; Ciencias de la Salud; Osasun Zientziak
Introduction: Rapid microbiology reporting can enhance both clinical and economic outcomes. Material and Methods: This three-year, quasi-experimental study, single-group pretest¿posttest study, conducted at a university medical center, aimed to evaluate the clinical and economic impact of rapid microbiological identification reporting using MALDI-TOF MS. A total of 363 consecutive hospitalized patients with bacterial infections were evaluated, comparing a historical control group (CG, n = 183) with an intervention group (IG, n = 180). In the CG, microbiological information (bacterial identification and antibiotic susceptibility) was provided between 18:00 and 22:00 h, while in the IG, bacterial identification was reported between 12:00 and 14:00 h, and antibiotic susceptibility was reported between 18:00 and 22:00 h. Results: The IG demonstrated a significant reduction in the number of patients undergoing Microbiology (p = 0.01), Biochemistry (p = 0.05), C-Reactive Protein (p = 0.02), Radiological Tests (p = 0.05), Computed Tomography Tests (p = 0.04), and Pathology (p = 0.01). However, no statistically significant reduction was observed in economic costs related to microbiological testing (p = 0.76) or antibiotic consumption (p = 0.59). The timely reporting of microbiological identification to clinicians resulted in fewer patients undergoing additional diagnostic tests, ultimately contributing to reduced healthcare resource utilization without adversely affecting clinical outcomes.

Accelerated forgetting in temporal lobe epilepsy: When does it occur?
(Elsevier, 2021) Contador Castillo, Israel; Sánchez, Abraham; Kopelman, Michael D.; González de la Aleja, Jesús; Ruisoto Palomera, Pablo; Ciencias de la Salud; Osasun Zientziak
Objective: the main goal of the study was to analyse differences in the forgetting rates of Temporal Lobe Epilepsy (TLE) patients at different intervals (30 sec, 10 min, 1 day and 1 week) compared with those of healthy controls. A secondary aim of this research was to provide an assessment of the relationship between clinical epilepsy-related variables and forgetting rates in TLE patients. Method: the sample was composed of 14 TLE patients and 14 healthy matched controls. All participants underwent a full standardised neuropsychological assessment including general intelligence, executive functioning, memory, language and other variables, such as depression, anxiety or everyday memory failures. Two specific memory tasks, consisting of cued recall of 4 short stories and 4 routes, were carried out at four different intervals. Results: there was a significant difference between groups at 10-min interval on the stories task, with the TLE group displaying greater forgetting than healthy controls. None of the other intervals on either task showed significant group differences. No differences were found when controlling for clinical epilepsy-related variables. Conclusion: forgetting of verbal information at 10 min was greater in patients with TLE compared with controls, but accelerated longer term forgetting was not found. This study suggests that a late consolidation process is not necessarily impaired in TLE patients.

Accuracy of smartwatch electrocardiographic recording in the acute coronary syndrome setting: rationale and design of the ACS WATCH II Study
(MDPI, 2024) Buelga Suárez, Mauro; Pascual Izco, Marina; García Montalvo, Jesús; Alonso Salinas, Gonzalo Luis; Ciencias de la Salud; Osasun Zientziak
Background: Acute Coronary Syndrome (ACS), with or without ST-segment elevation, is a major contributor to global mortality and morbidity. Swift diagnosis and treatment are vital for mitigating cardiac damage and improving long-term outcomes. The 12-lead electrocardiogram (ECG) currently serves as the gold standard for diagnosis in ACS with ST-segment elevation and may support the diagnosis in ACS without ST-segment elevation. However, the growing prevalence of smartwatches enables the acquisition of electrocardiographic data without traditional ECG equipment. While smaller studies support smartwatch ECG use, larger-scale validation within ACS remains lacking. The ACS WATCH II study aims to validate smartwatch ECG recordings for ACS. Methods: The primary objective is to validate smartwatch-obtained electrocardiographic data in patients presenting with ACS. Two cohorts of 120 patients each, presenting ACS with and without ST-segment elevation, will be assessed. Smartwatches will capture recordings of leads I, III, and V2 alongside standard ECGs. These leads, chosen due to a 97% ACS diagnosis sensitivity in previous studies, will undergo blind evaluation by two experienced external assessors against conventional ECG. Additionally, a control sample of 60 healthy individuals will be included. Conclusions: ACS WATCH II pioneers large-scale prospective validation of smartwatch ECG recordings in ACS patients. Additionally, it indirectly validates a swift diagnostic approach using three leads (I, III, and V2). This could expedite time-critical ACS diagnoses and simplify access through smartwatch-based diagnosis.

Acidification asymmetrically affects voltage-dependent anion channel implicating the involvement of salt bridges
(Elsevier, 2014-06-24) Teijido Hermida, Óscar; Rappaport, Shay M.; Chamberlin, Adam; Noskov, Sergei Y.; Aguilella, Vicente M.; Rostovtseva, Tatiana K.; Bezrukov, Sergey M.; Ciencias de la Salud; Osasun Zientziak
The voltage-dependent anion channel (VDAC) is the major pathway for ATP, ADP, and other respiratory substrates through the mitochondrial outer membrane, constituting a crucial point of mitochondrial metabolism regulation. VDAC is characterized by its ability to 'gate' between an open and several 'closed' states under applied voltage. In the early stages of tumorigenesis or during ischemia, partial or total absence of oxygen supply to cells results in cytosolic acidification. Motivated by these facts, we investigated the effects of pH variations on VDAC gating properties. We reconstituted VDAC into planar lipid membranes and found that acidification reversibly increases its voltage-dependent gating. Furthermore, both VDAC anion selectivity and single channel conductance increased with acidification, in agreement with the titration of the negatively charged VDAC residues at low pH values. Analysis of the pH dependences of the gating and open channel parameters yielded similar pKa values close to 4.0. We also found that the response of VDAC gating to acidification was highly asymmetric. The presumably cytosolic (cis) side of the channel was the most sensitive to acidification, whereas the mitochondrial intermembrane space (trans) side barely responded to pH changes. Molecular dynamic simulations suggested that stable salt bridges at the cis side, which are susceptible to disruption upon acidification, contribute to this asymmetry. The pronounced sensitivity of the cis side to pH variations found here in vitro might provide helpful insights into the regulatory role of VDAC in the protective effect of cytosolic acidification during ischemia in vivo.

Actionable driver events in small cell lung cancer
(MDPI, 2024) Gutiérrez Núñez, Mirian; Zamora Álvarez, Irene; Freeman, Michael R.; Encío Martínez, Ignacio; Rotinen Díaz, Mirja Sofia; Ciencias de la Salud; Osasun Zientziak
Small cell lung cancer (SCLC) stands out as the most aggressive form of lung cancer, characterized by an extremely high proliferation rate and a very poor prognosis, with a 5-year survival rate that falls below 7%. Approximately two-thirds of patients receive their diagnosis when the disease has already reached a metastatic or extensive stage, leaving chemotherapy as the remaining first-line treatment option. Other than the recent advances in immunotherapy, which have shown moderate results, SCLC patients cannot yet benefit from any approved targeted therapy, meaning that this cancer remains treated as a uniform entity, disregarding intra- or inter-tumoral heterogeneity. Continuous efforts and technological improvements have enabled the identification of new potential targets that could be used to implement novel therapeutic strategies. In this review, we provide an overview of the most recent approaches for SCLC treatment, providing an extensive compilation of the targeted therapies that are currently under clinical evaluation and inhibitor molecules with promising results in vitro and in vivo.

(BioMed Central, 2018) García Hermoso, Antonio; Quintero, Andrea P.; Hernández, Enrique; Izquierdo Redín, Mikel; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak
Background: There is limited evidence concerning how active commuting (AC) is associated with health benefits in young. The aim of the study was to analyze the relationship between AC to and from campus (walking) and obesity and metabolic syndrome (MetS) in a sample of Colombian university students. Methods: A total of 784 university students (78.6% women, mean age = 20.1 ± 2.6 years old) participated in the study. The exposure variable was categorized into AC (active walker to campus) and non-AC (non/infrequent active walker to campus: car, motorcycle, or bus) to and from the university on a typical day. MetS was defined in accordance with the updated harmonized criteria of the International Diabetes Federation criteria. Results: The overall prevalence of MetS was 8.7%, and it was higher in non-AC than AC to campus. The percentage of AC was 65.3%. The commuting distances in this AC from/to university were 83.1%, 13.4% and 3.5% for < 2 km, 2-5 km and > 5 km, respectively. Multiple logistic regressions for predicting unhealthy profile showed that male walking commuters had a lower probability of having obesity [OR = 0.45 (CI 95% 0.25–0.93)], high blood pressure [OR = 0.26 (CI 95% 0.13–0.55)] and low HDL cholesterol [OR = 0.29 (CI 95% 0.14–0.59)] than did passive commuters. Conclusions: Our results suggest that in young adulthood, a key life-stage for the development of obesity and MetS, AC could be associated with and increasing of daily physical activity levels, thereby promoting better cardiometabolic health.

Actores colectivos y modelos de conflicto en el estado de bienestar
(Centro de Investigaciones Sociológicas, 1993) Colom González, Francisco; Ciencias de la Salud; Osasun Zientziak
La dinámica histórica del "Estado de bienestar", su tan anunciada crisis y su no menos incierto futuro, puede ser mejor comprendida si se la concibe como el fruto de una determinada constelación histórica de estrategias organizativas, frentes de conflicto y actores colectivos. Esa constelación permite configurarlo teóricamente como un espacio político en el que confluyen tres modelos distintos de confrontación de intereses: los del capital y del trabajo, los de la politica institucionalizada y los expresados en formas extrainstitucionales de protesta. De su capacidad institucional para resolver esos tipos de conflicto, así como del recíproco ajuste de equilibrio entre sus escenarios, depende en buena medida el futuro político de los Estados de bienestar.

Acute and time-course changes in hemodynamic and physical performance parameters following single and multiple resistance training sets in cognitively impaired individuals: a randomized crossover study
(Elsevier, 2025-01-23) Fonseca, Nuno; Esteves, Dulce; Marques, Diogo Luís ; Faíl, Luís Brandão; Sousa, Tiago ; Pamplona Pinto, Mafalda ; Neiva, Henrique P.; Izquierdo Redín, Mikel; Marqués, Mário C.; Ciencias de la Salud; Osasun Zientziak
This study analyzed the acute and time-course changes following one resistance training (RT) set (1SET) and three sets (3SET) on hemodynamic and physical performance parameters in individuals with different cognitive impairment levels. Thirty-nine individuals (22 women and 17 men aged 80 ± 9 years) grouped by cognitive impairment (mild [MILD], moderate [MOD], and severe [SEV]) randomly performed two protocols, each separated by one week, of 1SET or 3SET of 10 repetitions. Before (PRE), immediately (POST), and 72 h after (POST72) protocols, the participants performed the following measurements: systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), 1-kg medicine ball throw (MBT) distance, five-repetition sit-to-stand (STS) time, and handgrip strength (HGS). A three-way ANOVA with repeated measures revealed no significant differences between 1SET and 3SET on SBP, DBP, HR, STS, MBT, and HGS in any group at any time (all p ¿ 0.05). SEV increased SBP and HR from PRE to POST and decreased STS time after 3SET. From POST to POST72, all groups decreased SBP after both protocols, and SEV improved STS time after 3SET and HGS following both protocols. Furthermore, from PRE to POST72, MILD decreased SBP, while SEV improved HGS following 1SET and STS time following 3SET. These findings demonstrate that single and multiple sets cause acute hemodynamic changes, with a tendency to reduce SBP within 72 h. Additionally, individuals with worse cognitive function showed greater adaptive responses over time in physical performance, with 1SET improving HGS and 3SET enhancing STS performance.

(Frontiers Media, 2018) Domínguez Sánchez, María Andrea; Bustos Cruz, Rosa H.; Velasco Orjuela, Gina P.; Quintero, Andrea P.; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak
The purpose of this study was to compare the neurotrophic factor response following one session of high-intensity exercise, resistance training or both in a cohort of physically inactive overweight adults aged 18–30 years old. A randomized, parallel-group clinical trial of 51 men (23.6 ± 3.5 years; 83.5 ± 7.8 kg; 28.0 ± 1.9 kg/m2) who are physically inactive (i.e., < 150 min of moderate-intensity exercise per week or IPAQ score of <600 MET min/week for >6 months) and are either abdominally obese (waist circumference ≥90 cm) or have a body mass index, BMI ≥25 and ≤ 30 kg/m2 were randomized to the following four exercise protocols: high-intensity exercise (4 × 4 min intervals at 85–95% maximum heart rate [HRmax] interspersed with 4 min of recovery at 75–85% HRmax) (n = 14), resistance training (12–15 repetitions per set, at 50–70% of one repetition maximum with 60 s of recovery) (n = 12), combined high-intensity and resistance exercise (n = 13), or non-exercising control (n = 12). The plasma levels of neurotrophin-3 (NT-3), neurotrophin-4 (also known as neurotrophin 4/5; NT-4 or NT-4/5), and brain-derived neurotrophic factor (BDNF) were determined before (pre-exercise) and 1-min post-exercise for each protocol session. Resistance training induced significant increases in NT-3 (+39.6 ng/mL [95% CI, 2.5–76.6; p = 0.004], and NT-4/5 (+1.3 ng/mL [95% CI, 0.3–2.3; p = 0.014]), respectively. Additionally, combined training results in favorable effects on BDNF (+22.0, 95% CI, 2.6–41.5; p = 0.029) and NT-3 (+32.9 ng/mL [95% CI, 12.3–53.4; p = 0.004]), respectively. The regression analysis revealed a significant positive relationship between changes in BDNF levels and changes in NT-4/5 levels from baseline to immediate post-exercise in the combined training group (R2 = 0.345, p = 0.034) but not the other intervention groups. The findings indicate that acute resistance training and combined exercise increase neurotrophic factors in physically inactive overweight adults. Further studies are required to determine the biological importance of changes in neurotrophic responses in overweight men and chronic effects of these exercise protocols.

Acute effects of high-intensity interval training session and endurance exercise on pulmonary function and cardiorespiratory coupling
(Wiley, 2020) Andrade, David C.; Arce Álvarez, Alexis; Parada, Felipe; Vásquez Muñoz, Manuel; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak
The aim of this study was to determine the acute effects of high-intensity interval training (HIIT) exercise and endurance exercise (EE) on pulmonary function, sympathetic/parasympathetic balance, and cardiorespiratory coupling (CRC) in healthy participants. Using a crossover repeated-measurements design, four females and four males were exposed to EE (20 min at 80% maximal heart rate [HR]), HIIT (1 min of exercise at 90% maximal HR per 1 min of rest, 10 times), or control condition (resting). Pulmonary function, HR, CRC, and heart rate variability (HRV) were assessed before and after the interventions. Results revealed no significant effects of EE or HIIT on pulmonary function. The EE, but not HIIT, significantly increased CRC. In contrast, HRV was markedly changed by HIIT, not by EE. Indeed, both the low-frequency (LFHRV) and high-frequency (HFHRV) components of HRV were increased and decreased, respectively, after HIIT. The increase in LFHRV was greater after HIIT than after EE. Therefore, a single bout of HIIT or EE has no effects on pulmonary function. Moreover, CRC and cardiac autonomic regulation are targeted differently by the two exercise modalities.

Acute endocrine and force responses and long-term adaptations to same-session combined strength and endurance training in women
(National Strength and Conditioning Association, 2016) Eklund, Daniela; Schumann, Moritz; Kraemer, William J.; Izquierdo Redín, Mikel; Taipale, Ritva S.; Ciencias de la Salud; Osasun Zientziak
This study examined acute hormone and force responses and strength and endurance performance and muscle hypertrophy before and after 24 weeks of same-session combined strength and endurance training in previously untrained women. Subjects were assigned 1 of 2 training orders: endurance preceding strength (E + S, n = 15) or vice versa (S + E, n = 14). Acute force and hormone responses to a combined loading (continuous cycling and a leg press protocol in the assigned order) were measured. Additionally, leg press 1 repetition maximum (1RM), maximal workload during cycling (Wmax), and muscle cross-sectional area (CSA) were assessed. Loading-induced decreases in force were significant (p < 0.01–0.001) before (E + S = 20 ± 11%, S + E = 18 ± 5%) and after (E + S = 24 ± 6%, S + E = 22 ± 8%) training. Recovery was completed within 24 hours in both groups. The acute growth hormone (GH) response was significantly (p < 0.001) higher after S + E than E + S at both weeks 0 and 24. Testosterone was significantly (p < 0.001) elevated only after the S + E loading at week 24 but was not significantly different from E + S. Both groups significantly (p < 0.001) improved 1RM (E + S = 13 ± 12%, S + E = 16 ± 10%), Wmax (E + S = 21 ± 10%, S + E = 16 ± 12%), and CSA (E + S = 15 ± 10%, S + E = 11 ± 8%). This study showed that the acute GH response to combined endurance and strength loadings was significantly larger in S + E compared with E + S both before and after 24 weeks of same-session combined training. Strength and endurance performance and CSA increased to similar extents in both groups during 24 weeks despite differences in the kinetics of GH. Previously untrained women can improve performance and increase muscle CSA using either exercise order.

ADAM12 is a potential therapeutic target regulated by hypomethylation in triple-negative breast cancer
(MDPI, 2020) Mendaza Lainez, Saioa; Ulazia Garmendia, Ane; Monreal Santesteban, Iñaki; Córdoba Iturriagagoitia, Alicia; Ruiz de Azúa, Yerani; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype and currently lacks any effective targeted therapy. Since epigenetic alterations are a common event in TNBC, DNA methylation profiling can be useful for identifying potential biomarkers and therapeutic targets. Here, genome-wide DNA methylation from eight TNBC and six non-neoplastic tissues was analysed using Illumina Human Methylation 450K BeadChip. Results were validated by pyrosequencing in an independent cohort of 50 TNBC and 24 non-neoplastic samples, where protein expression was also assessed by immunohistochemistry. The functional role of disintegrin and metalloproteinase domain-containing protein 12(ADAM12) in TNBC cell proliferation, migration and drug response was analysed by gene expression silencing with short hairpin RNA. Three genes (Von Willenbrand factor C and Epidermal Growth Factor domain-containing protein (VWCE), tetraspanin-9 (TSPAN9) and ADAM12) were found to be exclusively hypomethylated in TNBC. Furthermore, ADAM12 hypomethylation was associated with a worse outcome in TNBC tissues and was also found in adjacent-to-tumour tissue and, preliminarily, in plasma from TNBC patients. In addition, ADAM12 silencing decreased TNBC cell proliferation and migration and improved doxorubicin sensitivity in TNBC cells. Our results indicate that ADAM12 is a potential therapeutic target and its hypomethylation could be a poor outcome biomarker in TNBC.

Additive effects of a family history of schizophrenia spectrum disorders and an environmental risk score for the outcome of patients with non-affective first-episode psychosis
(Cambridge University Press, 2024) Cuesta Zorita, Manuel Jesús; García de Jalón, Elena; Sánchez Torres, Ana María; Gil Berrozpe, Gustavo José; Aranguren Conde, Lidia; Gutiérrez, Gerardo; Corrales, Asier; Zarzuela, Amalia; Ibáñez Beroiz, Berta; Peralta Martín, Víctor; PEPsNa Group; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua
Background: First-episode psychotic disorders comprise a heterogeneous phenotype with a complex etiology involving numerous common small-effect genetic variations and a wide range of environmental exposures. We examined whether a family of schizophrenia spectrum disorder (FH-Sz) interacts with an environmental risk score (ERS-Sz) regarding the outcome of patients with non-affective first episode psychosis (NAFEP). Methods: We included 288 patients with NAFEP who were evaluated after discharge from an intensive 2-year program. We evaluated three outcome measures: symptomatic remission, psychosocial functioning, and personal recovery. We analyzed the main and joint associations of a FH-Sz and the ERS-Sz on the outcomes by using the relative excess risk due to interaction (RERI) approach. Results: A FH-Sz showed a significant association with poor symptomatic remission and psychosocial functioning outcomes, although there was no significant interaction between a FH-Sz and the ERS-Sz on these outcomes. The ERS-Sz did not show a significant association with poor symptomatic remission and psychosocial functioning outcomes, even though the magnitude of the interaction between ERS-Sz and FH-Sz with the later outcome was moderate (RERI = 6.89, 95% confidence interval -16.03 to 29.81). There was no association between a FH-Sz and the ERS-Sz and personal recovery. Conclusions: Our results provide further empirical support regarding the contribution of FH-Sz to poor symptomatic remission and poor psychosocial functioning outcomes in patients with NAFEP.

Adherence of long-term breast cancer survivors to follow-up care guidelines: a study based on real-world data from the SURBCAN cohort
(Springer, 2022) Santiá, Paula; Jansana, Anna; Cura, Isabel del; Padilla-Ruiz, María; Domingo, Laia; Louro, Javier; Comas, Mercé; Sanz, Teresa; Duarte-Salles, Talita; Redondo, Maximino; Ibáñez Beroiz, Berta; Prados-Torres, Alexandra; Castells, Xavier; Sala, María; Ciencias de la Salud; Osasun Zientziak
Purpose: to identify adherence to follow-up recommendations in long-term breast cancer survivors (LTBCS) of the SURBCAN cohort and to identify its determinants, using real-world data. Methods: we conducted a retrospective study using electronic health records from 2012 to 2016 of women diagnosed with incident breast cancer in Spain between 2000 and 2006 and surviving at least 5 years. Adherence to basic follow-up recommendations, adherence according to risk of recurrence, and overall adherence were calculated based on attendance at medical appointments and imaging surveillance, by year of survivorship. Logistic regression models were fitted to depict the association between adherence and its determinants. Results: a total of 2079 LTBCS were followed up for a median of 4.97 years. Of them, 23.6% had survived >= 10 years at baseline. We estimated that 79.5% of LTBCS were overall adherent to at least one visit and one imaging test. Adherence to recommendations decreased over time and no differences were found according to recurrence risk. Determinants of better overall adherence were diagnosis in middle age (50-69 years old), living in a more-deprived area, having fewer years of survival, receiving primary treatment, and being alive at the end of follow-up. Conclusion: we identified women apparently not complying with surveillance visits and tests. Special attention should be paid to the youngest and eldest women at diagnosis and to those with longer survival.

Adherence to the Mediterranean diet in college students: evaluation of psychometric properties of the KIDMED questionnaire
(MDPI, 2020) Atencio Osorio, Miguel Alejandro; Carrillo Arango, Hugo Alejandro; Correa Rodríguez, María; Ochoa Muñoz, Andrés Felipe; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, ID 420/2019
No prior studies have examined the reliability properties of the 16-item Mediterranean Diet Quality Index (KIDMED) questionnaire among young adults from a non-Mediterranean country. The objective of this study was to determine the psychometric properties in terms of the reliability and validity of the KIDMED questionnaire in young adults from Colombia. A cross-sectional validation study was conducted among 604 Colombian college students (47.51% men and 52.48% women; mean age of 21.60 ± 2.02 years). Kappa statistics were used to assess the reliability of the KIDMED questionnaire. A categorical principal components analysis was used to determine validity. Based on the KIDMED score, 58.4% of students had a good adherence to the Mediterranean diet (MedDiet). Good agreement in the general score of the questionnaire was observed (κ = 0.727, 95% confidence interval = 0.676 to 0.778, p < 0.001). A five-factor model was identified which explained almost 51.38% of the variability, showing the multidimensionality of the questionnaire. In conclusion, this study provides reasonable evidence for the reliability and validity of the KIDMED questionnaire for assessing adherence to MedDiet in college students within a Latin American country. The evaluation of the psychometric properties of this tool in early adulthood and in a non-Mediterranean country will be useful in clinical practice and epidemiological research, since practitioners and health researchers now have a valid and reliable short scale.

Adherencia a la dieta mediterránea en una población escolar colombiana: evaluación de las propiedades psicométricas del cuestionario KIDMED
(Arán, 2020) Carrillo Arango, Hugo Alejandro; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak
Objetivo: como la infancia y la adolescencia son periodos críticos para la adquisición de hábitos alimentarios y estilos de vida que serán perdurables en la edad adulta, contar con un cuestionario que estime la adherencia a la dieta mediterránea de la población escolar es necesario. El objetivo de este estudio fue evaluar las propiedades psicométricas, en términos de fiabilidad, reproducibilidad y validez, del cuestionario KIDMED en un grupo de niños y adolescentes de Cali, Colombia. Métodos: estudio transversal de 167 escolares (53,8 % niñas, edad media de 13,3 ± 3,2 años). El alfa de Cronbach y el kappa de Cohen (κ) se calcularon como indicadores de fiabilidad y reproducibilidad. Un análisis factorial exploratorio, con un método de extracción de componentes principales y rotación ortogonal (varimax), se aplicó como medida de validez. Resultados: en la población general, 1 de cada 3 escolares acusaron un patrón de alimentación mediterránea óptima. El cuestionario KIDMED mostró valores de fiabilidad y reproducibilidad moderados (alfa de Cronbach = 0,79; IC 95 %: 0,71-0,77, y κ = 0,66; IC 95 %: 0,45-0,77). La composición factorial exploratoria arrojó seis factores que explicaron el 60,6 % de la varianza total y adecuados valores de bondad del ajuste (Kaiser-Meyer-Olkin = 0,730) y del test de esfericidad de Bartlett (χ2 = 414,8, p < 0.001, g/l = 120). Conclusión: el cuestionario KIDMED cuenta con propiedades psicométricas adecuadas como instrumento de valoración de la adherencia a la dieta mediterránea en escolares de Colombia. Futuros estudios deberán centrarse en investigar la estructura confirmatoria y/o la validez convergente del cuestionario en diferentes grupos de edad para generar datos comparables.
