RESUMEN

The NIMH-funded Multilevel Community-Based Mental Health Intervention to Address Structural Inequities and Adverse Disparate Consequences of COVID-19 Pandemic on Latinx Immigrants and African Refugees study aims to advance the science of multilevel interventions to reduce the disparate, adverse mental health, behavioral, and socioeconomic consequences of the COVID-19 pandemic that are a result of complex interactions between underlying structural inequities and barriers to health care. The study tests three nested levels of intervention: 1) an efficacious 4-month advocacy and mutual learning model (Refugee and Immigrant Well-being Project, RIWP); 2) engagement with community-based organizations (CBOs); and 3) structural policy changes enacted in response to the pandemic. This community-based participatory research (CBPR) study builds on long-standing collaboration with five CBOs. By including 240 Latinx immigrants and 60 African refugees recruited from CBO partners who are randomly assigned to treatment-as-usual CBO involvement or the RIWP intervention and a comparison group comprised of a random sample of 300 Latinx immigrants, this mixed methods longitudinal waitlist control group design study with seven time points over 36 months tests the effectiveness of the RIWP intervention and engagement with CBOs to reduce psychological distress, daily stressors, and economic precarity and increase protective factors (social support, access to resources, English proficiency, cultural connectedness). The study also tests the ability of the RIWP intervention and engagement with CBOs to increase access to the direct benefits of structural interventions. This paper reports on the theoretical basis, design, qualitative and quantitative analysis plan, and power for the study.

RESUMEN

Cerium oxide particles are a unique material that enables studying the intersection of metal oxides, f-elements, and nanomaterials. Distinct from diverse applications in catalysis, energy, and medicine, cerium possesses additional influence as a non-radioactive actinide surrogate. Herein, we present a synthesis for sub-micron cerium particles using hexamethylenetetramine and ammonium hydroxide as precipitating agents with a CeIV precursor. The combinatorial homogeneous precipitation approach yields monodisperse and moderately-stable CeO2 particle suspensions in ethanol, as determined by powder X-ray diffraction, scanning electron microscopy, dynamic light scattering, and zeta potential measurements. Various additives may be used to moderate and manipulate the surface charge of the particles. Proof-of-concept electrophoretic deposition of the particles produces a uniform layer of CeO2 on graphite. The synthesis and suspension properties are developed as a methodology towards future controlled actinide hydrolysis and film deposition.

RESUMEN

BACKGROUND: Early palliative/pre-emptive intervention improves clinical outcomes and quality of life for patients with metastatic cancer. A previous signal-seeking randomized controlled trial (RCT) demonstrated that early upfront radiotherapy to asymptomatic or minimally symptomatic high-risk osseous metastases led to reduction in skeletal-related events (SREs), a benefit driven primarily by subgroup of high-risk spine metastasis. The current RCT aims to determine whether early palliative/pre-emptive radiotherapy in patients with high-risk, asymptomatic or minimally symptomatic spine metastases will lead to fewer SREs within 1 year. METHODS: This is a single-center, parallel-arm, in-progress RCT in adults (≥ 18 years) with ECOG performance status 0-2 and asymptomatic or minimally symptomatic (not requiring opioids) high-risk spine metastases from histologically confirmed solid tumor malignancies with > 5 sites of metastatic disease on cross-sectional imaging. High-risk spine metastases are defined by the following: (a) bulkiest disease sites ≥ 2 cm; (b) junctional disease (occiput to C2, C7-T1, T12-L2, L5-S1); (c) posterior element involvement; or (d) vertebral body compression deformity > 50%. Patients are randomized 1:1 to receive either standard-of-care systemic therapy (arm 1) or upfront, early radiotherapy to ≤ 5 high-risk spine lesions plus standard-of-care systemic therapy (arm 2), in the form of 20-30 Gy of radiation in 2-10 fractions. The primary endpoint is SRE, a composite outcome including spinal fracture, spinal cord compression, need for palliative radiotherapy, interventional procedures, or spinal surgery. Secondary endpoints include (1) surrogates of health care cost, including the number and duration of SRE-related hospitalizations; (2) overall survival; (3) pain-free survival; and (4) quality of life. Study instruments will be captured pre-treatment, at baseline, during treatment, and at 1, 3, 6, 12, and 24 months post-treatment. The trial aims to accrue 74 patients over 2 years to achieve > 80% power in detecting difference using two-sample proportion test with alpha < 0.05. DISCUSSION: The results of this RCT will demonstrate the value, if any, of early radiotherapy for high-risk spine metastases. The trial has received IRB approval, funding, and prospective registration (NCT05534321) and has been open to accrual since August 19, 2022. If positive, the trial will expand the scope and utility of spine radiotherapy. TRIAL REGISTRATION: ClinicalTrials.Gov NCT05534321 . Registered September 9, 2022. TRIAL STATUS: Version 2.0 of the protocol (2021-KOT-002), revised last on September 2, 2022, was approved by the WCG institutional review board (Study Number 1337188, IRB tracking number 20223735). The trial was first posted on ClinicalTrials.Gov on September 9, 2022 (NCT05534321). Patient enrollment commenced on August 19, 2022, and is expected to be completed in 2 years, likely by August 2024.

RESUMEN

Two indium(III) complexes of formula mer-[InIIICl3(4-Me-pzH)3] and trans-[InIIICl2(4-Me-pzH)4]Cl·(4-Me-pzH)2·(H2O) were isolated from the same reaction mixture and crystallographically characterized. The two complexes exist in dynamic equilibrium and their dynamic behavior was probed by variable temperature 1H NMR spectroscopy in the 202 to 296 K range. Powder X-ray diffraction of the batch confirmed existence of both complexes in a 1:2 ratio. Antibacterial properties of both new complexes, in addition to seven other previously published indium(III) complexes, were investigated against three Gram-positive and four Gram-negative pathogenic bacterial strains. The results showed potential for the development of indium(III)-based antipseudomonal and antituberculosis drugs, with mer-[InCl3(4-Ph-pzH)3] being especially effective.

RESUMEN

BACKGROUND: Few studies have evaluated the long-term impact on health-related quality of life (HRQoL) in patients who have been hospitalized for COVID-19 pneumonia. Specific follow-up should be carried out to detect and treat possible pulmonary abnormalities, and the worsening of HRQoL should be estimated to target necessary resources for care of these patients after acute phase. The objective was to know the impact on HRQoL of patients who have been admitted for COVID-19 pneumonia, and to evaluate the clinical-radiological and functional changes of patients who have overcome COVID-19 pneumonia at 3 and 10 months of follow-up. METHODS: Prospective observational study of patients who required hospitalization for COVID-19 pneumonia between April and December 2020. All patients filled out the EuroQol five-dimension (EQ-5D) questionnaire with the EuroQol Visual Analogue Scale (E-VAS) for self-assessment of health status. Respiratory function tests and chest X-ray were carried out at 3 and 10 months of follow-up. RESULTS: 61 patients were included in the study. The need for ventilatory support was associated with anxiety/depression on the EQ-5D scale, as well as patients admitted to the intensive care unit (ICU). The mean EQ-5D and E-VAS index scores decreased with hospitalization time, the number of days spent in intermediate respiratory care unit (IRCU) and the level of dyspnoea at the beginning of the hospitalization period. Pulmonary sequelae were observed in 25 patients (41%) at 3 months and 17 (27.9%) at 10 months. Patients improve their forced vital capacity (FVC) by 196 ml (p = 0.001) at 10 months as well as 9% in diffusing capacity of lung for carbon monoxide (DLCO) (p = 0.001) at 10 months. DLCO was found to be correlated to lymphopenia and time spent in IRCU. Low FVC values were detected 10 months after discharge for subjects exhibiting high levels of dyspnoea at 3 months after discharge. CONCLUSIONS: Hospitalization for COVID-19 pneumonia affects the HRQoL of patients, with greater anxiety/depression in those who were more serious affected and are younger. A significant percentage of patients present fibrotic abnormalities and lung function impairment at the first and second follow-up after discharge.

RESUMEN

OBJECTIVE: Cancer survivors often incur significant out-of-pocket costs; this can result in financial toxicity, defined as the adverse financial impact of cancer due to direct or indirect costs related to the disease. There has been little research on whether spirituality is associated with the experience of financial toxicity. In this study, we tested the hypothesis that spirituality would be inversely associated with financial toxicity. METHODS: We evaluated these associations in a cross-sectional study of Hispanic breast cancer survivors (n = 102) identified through the New Jersey State Cancer Registry. Participants completed the FACIT-Sp-12, which has two spirituality subscales (meaning/peace; faith). Financial toxicity was assessed using the 11-item COST measure; lower scores suggest worse toxicity. In multivariable linear regression analyses, we examined the associations between spirituality scores and financial toxicity, adjusting for age, race, education, household income, and insurance status. RESULTS: The spirituality total score (ß = 0.49, 95% confidence interval (CI): 0.17, 0.8), meaning/peace subscale score (ß = 0.71, 95% CI: 0.12, 1.31), and faith (ß = 0.71, 95% CI: 0.2, 1.21) subscale score were all inversely associated with financial toxicity. CONCLUSIONS: Spirituality may be an important factor in ameliorating the detrimental effects of financial toxicity among Hispanic breast cancer survivors and should be considered in interventions for financial toxicity in this population.

RESUMEN

BACKGROUND: The coronavirus disease (COVID-19) pandemic has already affected more than 400 million people, with increasing numbers of survivors. These data indicate that a myriad of people may be affected by pulmonary sequelae of the infection. The aim of this study was to evaluate pulmonary sequelae in patients with bilateral COVID-19 pneumonia according to severity 1 year after hospital discharge. METHODS: COVID-FIBROTIC is a multicenter prospective observational cohort study for admitted patients with bilateral COVID-19 pneumonia. Pulmonary functional outcomes and chest computed tomography sequelae were analyzed 12 months after hospital discharge and we classified patients into three groups according to severity. A post hoc analysis model was designed to establish how functional test changed between groups and over time. A multivariable logistic regression model was created to study prognostic factors for lung diffusion impairment and radiological fibrotic-like changes at 12 months. RESULTS: Among 488 hospitalized patients with COVID-19 pneumonia, 284 patients had completed the entire evaluation at 12 months. Median age was 60.5 ± 11.9 and 55.3% were men. We found between-group differences in male sex, length of hospital stay, radiological involvement and inflammatory laboratory parameters. The functional evaluation of pulmonary sequelae showed that severe patients had statistically worse levels of lung diffusion at 2 months but no between group differences were found in subsequent controls. At 12-month follow up, however, we found impaired lung diffusion in 39.8% unrelated to severity. Radiological fibrotic-like changes at 12 months were reported in 22.7% of patients (102/448), only associated with radiological involvement at admission (OR: 1.55, 95% CI 1.06-2.38; p = 0.02) and LDH (OR: 0.99, 95% CI 0.98-0.99; p = 0.046). CONCLUSION: Our data suggest that a significant percentage of individuals would develop pulmonary sequelae after COVID 19 pneumonia, regardless of severity of the acute process. Trial registration clinicaltrials.gov NCT04409275 (June 1, 2020).

RESUMEN

A new family of six mononuclear indium(III) complexes of formula mer-[InIIICl3(pz*H)3]-pz*H = pyrazole (pzH), or substituted pyrazoles: 4-Cl-pzH, 4-Br-pzH, 4-I-pzH, 4-Ph-pzH and 3,5-Me2-pzH-were synthesized by addition reactions of InCl3 and pz*H and crystallographically characterized. The fluxional behaviour of the complexes, probed by variable temperature 1H NMR spectroscopy in the 328 K to 173 K range, was attributed to (at least) four simultaneous processes: pyrazole N-H proton dissociation/association, cis/trans-pyrazole exchange, and N1/N2 tautomerization of the cis- and of the trans-pyrazoles. Three novel trianionic hexanuclear complexes of general formula (pipH)3[In6Cl6(µ3-OH0.5)2(µ-OH)6(µ-pz*)6]-pz* = pz, 4-Cl-pz and 4-Ph-pz-showing µ-hydroxo and µ-oxo bridges were synthesized from the corresponding mer-[InIIICl3(pz*H)3] and characterized by single crystal X-ray diffraction and 1H NMR. Under different solvent conditions, multicolour emitting polymeric complexes of general formula [In(µ-pz*)3]n-pz* = pz, 4-Cl-pz, 4-I-pz and 4-Ph-pz-were obtained also from mer-[InIIICl3(pz*H)3] after addition of a base. Luminescence and lifetime calculations were performed for all polymers formed.

RESUMEN

The aim of this article is to evaluate the effectiveness of the implementation of a psycho-educational intervention programme. The objective of this programme was to achieve optimisation of self-concept and basic socio-emotional skills for comprehensive development in the adolescent stage. The sample consisted of 402 students from 19 groups from public secondary schools in the province of Badajoz. A quasi-experimental pretest-posttest design was applied with a control group using the Trait Meta-Mood Scale, Self-Concept Form 5, and the State-Trait Anxiety Inventory. The analysis showed that the programme was effective in the family and social dimensions of self-concept, while in the other dimensions, the changes were not statistically significant. The results for emotion perception, understanding and regulation show that there were no statistically significant differences in the experimental group, although there were significant differences in the control group.

RESUMEN

Physical exercise and physical activity are inherent and essential agents in the evolution of active life and are associated with promoting health and well-being. This study aimed to examine the types of regulation of motivations and intentionality needed to be physically active in the future in university students from the Health Sciences branch of knowledge. Method: 351 university students with six university degrees in Health Sciences participated, 21.4% of whom were male and 78.6% women (M = 19.32; SD = 4.01). They answered the following questionnaires: "International Physical Activity Questionnaire (IPAQ)", "Behavioural Regulation of Exercise Questionnaire (BREQ-3)", and "Intention to be physically active (MIFAU)". Results: intrinsic motivation and integrated regulation were positively associated (rho = 0.759; p < 0.01), as were integrated and identified codes (rho = 0.645; p < 0.01). When relating the types of motivation regulation and the intention to be physically active, men show a significant difference compared to women. It stands out that physically active people who walk are the most unmotivated (p < 0.01). Conclusions: more self-determined regulations and intentionality to be physically active are related to different physical activity levels and the number of METs.

RESUMEN

INTRODUCTION: Impairment in pulmonary function tests and radiological abnormalities are a major concern in COVID-19 survivors. Our aim is to evaluate functional respiratory parameters, changes in chest CT, and correlation with peripheral blood biomarkers involved in lung fibrosis at two and six months after SARS-CoV-2 pneumonia. METHODS: COVID-FIBROTIC (clinicaltrials.gov NCT04409275) is a multicenter prospective observational cohort study aimed to evaluate discharged patients. Pulmonary function tests, circulating serum biomarkers, chest radiography and chest CT were performed at outpatient visits. RESULTS: In total, 313, aged 61.12 ± 12.26 years, out of 481 included patients were available. The proportion of patients with DLCO < 80% was 54.6% and 47% at 60 and 180 days. Associated factors with diffusion impairment at 6 months were female sex (OR: 2.97, 95%CI 1.74-5.06, p = 0.001), age (OR: 1.03, 95% CI: 1.01-1.05, p = 0.005), and peak RALE score (OR: 1.22, 95% CI 1.06-1.40, p = 0.005). Patients with altered lung diffusion showed higher levels of MMP-7 (11.54 ± 8.96 vs 6.71 ± 4.25, p = 0.001), and periostin (1.11 ± 0.07 vs 0.84 ± 0.40, p = 0.001). 226 patients underwent CT scan, of whom 149 (66%) had radiological sequelae of COVID-19. In severe patients, 68.35% had ground glass opacities and 38.46% had parenchymal bands. Early fibrotic changes were associated with higher levels of MMP7 (13.20 ± 9.20 vs 7.92 ± 6.32, p = 0.001), MMP1 (10.40 ± 8.21 vs 6.97 ± 8.89, p = 0.023), and periostin (1.36 ± 0.93 vs 0.87 ± 0.39, p = 0.001). CONCLUSION: Almost half of patients with moderate or severe COVID-19 pneumonia had impaired pulmonary diffusion six months after discharge. Severe patients showed fibrotic lesions in CT scan and elevated serum biomarkers involved in pulmonary fibrosis.


INTRODUCCIÓN: El deterioro de la función pulmonar en las pruebas correspondientes y las alteraciones radiológicas son las preocupaciones principales en los supervivientes de la COVID-19. Nuestro objetivo fue evaluar los parámetros de la función respiratoria, los cambios en la TC de tórax y la correlación con los biomarcadores en sangre periférica involucrados en la fibrosis pulmonar a los 2 y a los 6 meses tras la neumonía por SARS-CoV-2. MÉTODOS: El ensayo COVID-FIBROTIC (clinicaltrials.gov NCT04409275) es un estudio de cohortes multicéntrico, prospectivo y observacional cuyo objetivo fue evaluar los pacientes dados de alta. Se realizaron pruebas de función pulmonar, detección de biomarcadores en plasma circulante y radiografía y TC de tórax durante las visitas ambulatorias. RESULTADOS: En total 313 pacientes, de 61,12 ± 12,26 años, de los 481 incluidos estuvieron disponibles.La proporción de pacientes con DLCO < 80% fue del 54,6 y del 47% a los 60 y 180 días.Los factores que se asociaron a la alteración de la difusión a los 6 meses fueron el sexo femenino (OR: 2,97; IC del 95%: 1,74-5,06; p = 0,001), la edad (OR: 1,03; IC del 95%: 1,01-1,05; p = 0,005) y la puntuación RALE más alta (OR: 1,22; IC del 95%: 1,06-1,40; p = 0,005). Los pacientes con alteración de la difusión pulmonar mostraron niveles más altos de MMP-7 (11,54 ± 8,96 frente a 6,71 ± 4,25; p = 0,001) y periostina (1,11 ± 0.07 frente a 0,84 ± 0,40; p = 0,001). Se le realizó una TC a 226 pacientes de los cuales 149 (66%) presentaban secuelas radiológicas de la COVID-19. En los pacientes graves, el 68,35% mostraban opacidades en vidrio esmerilado y el 38,46%, bandas parenquimatosas. Los cambios fibróticos tempranos se asociaron a niveles más altos de MMP7 (13,20 ± 9,20 frente a 7,92 ± 6,32; p = 0,001), MMP1 (10,40 ± 8,21 frente a 6,97 ± 8,89; p = 0,023), y periostina (1,36 ± 0,93 frente a 0,87 ± 0,39; p = 0,001). CONCLUSIÓN: Casi la mitad de los pacientes con neumonía moderada o grave por COVID-19 presentaba alteración de la difusión pulmonar 6 meses después del alta. Los pacientes graves mostraban lesiones fibróticas en laTC y un aumento de los biomarcadores séricos relacionados con la fibrosis pulmonar.

RESUMEN

Introduction: Physical activity plays an important role in all stages of development, especially in adolescence, as it is a period in which different lifestyles are shaped. Therefore, regular practice of physical activity contributes to an improvement in quality of life. This study analyzed university students' motivational processes and intention to be physically active when engaging in physical activity (PA) according to gender and fields of study. Methods: A total of 1.524 subjects participated in the study, 61.9% (n = 944) of whom were female and 38.1% (n = 580) were male, with an average age of 19.61 years. The fields of study consisted of Arts and Humanities (n = 118), Science (n = 132), Health Sciences (n = 351), Engineering and Architecture (n = 196) and Social and Legal Sciences (n = 727). The instruments used were the Behavioral Regulation in Exercise Questionnaire (BREQ-3) and the Intention to be Physically Active in the University Context (MIFAU) measurement scale. Results: The results showed statistically significant differences in favour of men (p <0.01) in terms of intrinsic, integrated, identified, and introjected regulation of PA. Similarly, men were more likely to be physically active in the future than women (p <0.001). In terms of the study variables relating to the fields of study, statistically significant differences were obtained in the case of both more self-determined behavior (intrinsic, integrated and identified regulation) and amotivation (p <0.001). Conclusion: It was concluded that there is a need for the promotion of intervention strategies to encourage young adults to take up sporting activities as a means of preventing noncommunicable diseases, thereby avoiding the negative consequences of a sedentary lifestyle, physical inactivity, or abandonment of such activities.

RESUMEN

This study examines personal and emotional metaphors of prospective economics teachers about the roles they themselves as teachers and their pupils would play by analysing their drawings and responses to open questions. This is a longitudinal study that analyses the evolution of future instructors using two periods: before and after their teaching practicum. Metaphors are categorised into four classes: behaviourist/transmissive, cognitivist/constructivist, situative/socio-historical, and self-referential. The categories for emotions are primary or social and positive, negative, or neutral. The results show that the highest percentage of metaphors for the teacher's role in both questionnaires were cognitivist/constructivist. Comparison of the findings before and after the teaching practicum revealed no changes in most of the participants' metaphors and associated models. The analysis also reveals that among those who change, the tendency is to evolve towards more pupil-centred metaphors and associated models. The most common pupil metaphors are behaviourist and cognitivist, increasing after the practicum. Finally, most of the emotions expressed are positive and social, also increasing after the practicum.

RESUMEN

The aim of this study was to determine the relationship between the motives for engaging in sports activities and the self-determination index (SDI) and how this in turn predicts the intentionality of future elementary school teachers to be physically active. METHOD: A total of 331 first-year students of the teacher training degree participated, 34.4% men and 65.6% women (M = 20.02; SD = 2.55). They answered the following questionnaires: "Behavioral Regulation in Exercise Questionnaire-3", "Motives for Physical Activity Measure-Revised" and "Intention to be Physically Active". RESULTS: Fitness, fun and care of one's appearance are the motives most valued by university students. A regression analysis (structural equation modeling) revealed that appearance and social motives were negatively related to SDI, although the model clearly predicted the intention to be physically active (R2 = 0.74). A second model, which positively related the appearance and competence motives with the intention to be active, improved the coefficient of determination (R2 = 90) and fit index. CONCLUSIONS: The motives for engaging in physical activity influence university students in different ways in relation to the SDI and strongly predict the intention to be physically active.

RESUMEN

En este estudio se analizan las dimensiones del autoconcepto, la inteligencia emocional y la ansiedad y su relación con variables sociodemográficas y académicas en 402 adolescentes de entre 12 y 19 años. Se aplicó la "Escala rasgo de metaconocimiento de los estados emocionales" (TMMS-24), el "Autoconcepto forma 5" (AF5) y el "Inventario de ansiedad estado-rasgo" (STAI y STAIC). Los resultados muestran que existen correlaciones negativas entre todas las dimensiones del autoconcepto y la ansiedad. La inteligencia emocional se relaciona con el autoconcepto físico y social. El sexo no influye en el autoconcepto global, pero sí en la ansiedad. Además, el sexo, la edad, el curso y las repeticiones predicen el autoconcepto emocional y la claridad emocional. Sin embargo, el tipo de programa educativo no predice ninguno de los constructos analizados. Sería deseable implementar programas de intervención dirigidos a la mejora del autoconcepto a través del entrenamiento en competencias emocionales y sociales y en control del estrés y la ansiedad


In this study we analyze the dimensions of self-concept, emotional intelligence and anxiety, as well as to analyse their relationship to sociodemographic and academic variables in a sample of 402 adolescents between 12 and 19 years of age. The instruments applied were the Trait Meta-Mood Scale (TMMS-24), the Self-concept Form "5" (AF5) and the State Trait Anxiety Inventory (STAI and STAIC). The outcomes show that negative correlations between all the dimensions of self-concept and anxiety. The emotional intelligence is related to the physical and social self-concept. Gender has no influence on the global self-concept, but on anxiety it does. The gender, age, course and repetitions predict the emotional self-concept and the emotional understanding. Repeating a year at school predicts the academic self-concept and gender predicts the physical self-concept, anxiety and emotional understanding. The type of educational programme does not predict any of the constructs analysed. It would be desirable to implement intervention programmes aimed at improving self-concept through training in emotional and social competences, as well as in controlling stress and anxiety

RESUMEN

Introducción: La difusión de los conocimientos biosanitarios y la rapidez con la que se difunden en Internet puede generar aprendizajes erróneos por falta de una formación científica adecuada, de ahí la necesidad de realizar intervenciones formativas sobre alfabetización en salud. Sujetos y métodos: Se ha realizado un estudio descriptivo cuasiexperimental para comprobar la eficacia de una estrategia educativa en torno a la alfabetización en salud. La muestra objeto de estudio procede de un posgrado oficial destinado a la formación de futuros profesores. Los estudiantes trabajaron un contenido mediante técnicas de aprendizaje tutorizado cooperativo. El instrumento de medida ha sido la evaluación de los conocimientos científicos adquiridos y las emociones experimentadas por los estudiantes. Resultados y conclusiones: El análisis estadístico realizado permite comprobar que la metodología empleada facilita la alfabetización en salud. Se discute su proyección desde el medio universitario a la sociedad, haciendo hincapié en los paralelismos existentes entre la alfabetización en salud y el empoderamiento de los pacientes


Introduction: The dissemination of biosanitary knowledge and the speed with which they spread on the Internet, can generate erroneous learning due to lack of adequate scientific training. Hence the need to carry out training interventions on health literacy. Subjects and methods: A descriptive, quasi-experimental study was carried out to verify the effectiveness of an educational strategy around health literacy. The sample under study comes from an official postgraduate course for the training of future professors. Students worked on content using cooperative tutoring learning techniques. The instrument of measurement has been the evaluation of the acquired scientific knowledge and the emotions experienced by the students. Results and conclusions: The statistical analysis performed shows that the methodology used facilitates health literacy. It discusses its projection from the university to society, emphasizing the parallels between the health literacy and the empowerment of patients

RESUMEN

Objetivo. Investigar el riesgo de padecer trastornos de la conducta alimentaria y del peso en estudiantes de medicina, un colectivo que debería ser modelo de actitudes y hábitos saludables. Sujetos y métodos. Participaron 116 estudiantes de medicina de la Universidad de Extremadura, que cumplimentaron el inventario de trastornos de la conducta alimentaria-3, cuestionario de remisión (EDI-3 RF). Resultados. Los varones destacaron en rasgos bulímicos, y las mujeres, en obsesión por estar delgadas y en insatisfacción con la propia imagen. Conclusiones. Un gran porcentaje de los estudiantes analizados estarían dentro de la población de riesgo de padecer trastornos de la conducta alimentaria. Por ello, esta investigación supone una herramienta docente activa para el fomento de conductas de alimentación saludable (AU)


Aim. To study the risk of suffering eating disorders among students of medicine, a group that should be an example for healthy habits. Subjects and methods.116 students of medicine from de University of Extremadura fill out the Eating Disorders Inventory-3, Referral Form (EDI-3 RF). Results. Male students suffer more bulimic characteristics and female students more thinness obsession and body dissatisfaction. Conclusions. A large extent of students would be among the risk group of suffering eating disorders. Therefore, this research is a practical tool to promote healthy eating habits (AU)

RESUMEN

UNLABELLED: Abstract Objective: No information is available on the effect of cigarette smoke on bronchoconstrictor-induced air trapping in asthma. The aim of this study was to evaluate the additional influence of smoking on methacholine- and adenosine 5'-monophosphate (AMP)-induced air trapping in subjects with asthma. METHODS: Airway responsiveness to methacholine and AMP, bronchial (J'awNO) and alveolar (CANO) nitric oxide (NO) and exhaled breath condensate pH were measured in 68 adults (23 current smokers with asthma, 23 non-smokers with asthma and 22 current or former smokers with chronic obstructive pulmonary disease; COPD). The degree of air trapping induced by each bronchoconstrictor agent was expressed by the percent fall in forced vital capacity (FVC) at a 20% fall in forced expiratory volume in 1 s relative to FVC after saline inhalation (ΔFVC%). RESULTS: The ΔFVC% for AMP was higher in both smokers with asthma and patients with COPD than in non-smokers with asthma (p<0.001). By contrast, ΔFVC% for methacholine was similar in the three groups of subjects (p=0.69). In smokers with asthma, but not in the other two groups, there was a correlation between the residual volume/total lung capacity at baseline and the ΔFVC% induced by each bronchoconstrictor agent. Mean values for J'awNO were higher in non-smokers with asthma than in the other two groups (p<0.05). CONCLUSIONS: The results of this study suggest that factors underlying bronchoconstriction induced by indirect agonists are different in smokers and non-smokers with asthma. These observations might be clinically relevant, because triggers that frequently induce bronchial obstruction in the real world act by an indirect mechanism.

RESUMEN

Entre julio de 1987 y mayo de 1989 se entrevistaron desde el punto de vista psicológico 200 pacientes quirúrgicos. La observación de 32 pacientes con cáncer primario o secundario en el pulmón motivó el presente trabajo. Se investigó la actitud psicológica del paciente frente a la operación y su evolución médica postoperatoria. La evaluación se realizó mediante entrevistas y los resultados se trasladaron a 3 formularios diferentes. El 91% de los pacientes deseaba ser escuchado y aceptó la atención psicológica. La evolución médica postoperatoria resultó ser un correlato significativo de la disposición psicológica observada en el preoperatorio; los 9 pacientes con una disposición psicológica normal no sufrieron complicaciones; de los 23 con una actitud prequirúrgica patológica, 12 tuvieron complicaciones médicas postoperatorias tales como, empiema, atelectasia, inexpansión pulmonar, hemorragia digestiva, trombosis venosa profunda, insuficiencia cardíaca, hemotórax postoperatorio, infección de pared y neumonitis.
