This paper examined the interaction between narrative performance, language exposure, and standardized measures of morphosyntax and semantics, in bilingual children tested two times, 1 year apart. We aimed to 1) identify the factor structure of oral narrative measures, and 2) examine the direction and strength of the effects of (i) language exposure and (ii) the relationship between language domains and narrative production. A total of 143 Spanish (L1)-English (L2) bilingual children completed a battery of oral narrative and oral language proficiency assessments in Spanish and English at two time points (kindergarten and Grade 1). Factor analyses yielded an identical two-factor structure of bilingual oral narrative measurements, namely productivity (word production) and complexity (sentence structure), in both Spanish and English across the two time points. Cross-lagged analysis showed that narrative production predicted semantics and morphosyntax performance in Spanish and English one year later. Cross-language transfer from L1 to L2 on the complexity of narrative was noted. Language exposure predicted only Spanish narrative production, but not English. These results suggest within- and cross-language transfer, highlighting the importance of L1 language development. In addition, current findings highlight the importance of language exposure for L1 in early school-age children.
Estimating the risk of developing bipolar disorder (BD) in children and adolescents (C&A) with depressive disorders is important to optimize prevention and early intervention efforts. We aimed to quantitatively examine the risk of developing BD from depressive disorders and identify factors which moderate this development.
Methods
In this systematic review and meta-analysis (PROSPERO:CRD42023431301), PubMed and Web-of-Science databases were searched for longitudinal studies reporting the percentage of C&A with ICD/DSM-defined depressive disorders who developed BD during follow-up. Data extraction, random-effects meta-analysis, between-study heterogeneity analysis, quality assessment, sub-group analyses, and meta-regressions were conducted.
Results
Thirty-nine studies were included, including 72,371 individuals (mean age=13.9 years, 57.1% females); 14.7% of C&A with a depressive disorder developed BD after 20.4–288 months: 9.5% developed BD-I (95% CI=4.7 to 18.1); 7.7% developed BD-II (95% CI=3.2% to 17.3%); 19.8% (95% CI=9.9% to 35.6%) of C&A admitted into the hospital with a depressive disorder developed BD. Studies using the DSM (21.6%, 95% CI=20.2% to 23.1%) and studies evaluating C&A with a major depressive disorder only (19.8%, 95% CI=16.8% to 23.1%) found higher rates of development of BD. Younger age at baseline, a history of hospitalization and recruitment from specialized clinics were associated with an increased risk of developing BD at follow-up. Quality of included studies was good in 76.9% of studies.
Conclusions
There is a substantial risk of developing BD in C&A with depressive disorders. This is particularly the case for C&A with MDD, DSM-diagnosed depressive disorders, and C&A admitted into the hospital. Research exploring additional predictors and preventive interventions is crucial.
Environmental impact has been poorly addressed in health technology assessment (HTA) processes despite its potential role in promoting more sustainable health systems. Initiatives to incorporate this dimension into economic evaluations (EE) that support HTA are few and far between. We aim to identify the state of the art and challenges for incorporating environmental impact into the EE of HTA.
Methods
We conducted a scoping review to identify publications on the assessment of the environmental dimension of health technologies from different approaches: establishment of theoretical frameworks and methods; data search strategies; identification of parameters, designs, and indicators; as well as descriptions of practical applications in HTA (literature review, EE, or budget impact analysis). The literature search was conducted through PubMed. Selected studies should provide insights to incorporate environmental impact into the EE of HTA regardless of the technology or environmental aspect considered (carbon footprint, use of resources, waste generation, etc.).
Results
From a total of 219 references initially identified, 22 publications meeting the selection criteria were found. The holistic approach is recognized as the most appropriate for incorporating the environmental dimension, through the evaluation of the entire life cycle of the technology, as well as the management of the disease and the use of resources throughout the care process. A large amount of information and accurate estimates about the impact of the technology are needed. Therefore, the first reported approaches have focused on particular aspects of the environmental impact of a health technology (mainly the carbon footprint).
Conclusions
The practical incorporation of the environmental dimension into the HTA is still very incipient. Foundations have begun to be established for its incorporation into economic evaluation. A consensus is required on the most appropriate methodologies and tools to collect the necessary data. It would also require a multidisciplinary approach and a framework for cooperation between all the stakeholders.
Suicide poses a severe public health challenge worldwide, impacting individuals, families, work, and society. The multifaceted nature of suicide demands a complex approach involving psychological, biological, social, cultural, and environmental factors. Recognizing suicide’s status as the leading external cause of death in Spain, prevention increasingly incorporates technology, specifically mobile and software applications.
Methods
A systematic review of the effectiveness and safety of mobile and software applications was conducted (MEDLINE, Embase, CINAHL, and PsycINFO databases). Outcome variables included: suicide; suicidal behavior; suicidal intent; suicidal ideation/thinking; self-perceived suicide risk; using/seeking mental health services; associated mental symptoms; mental health-related quality of life; satisfaction of the user and the health professional; adverse events related to the app, as defined in the included studies. Studies that do not include suicidal behavior, intention, or ideation were excluded. Where available data allowed, a meta-analysis was conducted for each outcome variable.
Results
One systematic review and 13 randomized controlled trials (n=2,952) were analyzed. No significant differences were found in deaths by suicide or suicide attempts. At post-intervention, small but significant reductions were observed in suicidal ideation, hopelessness, depression, and worry, with anxiety reduction slightly above statistical significance. At follow-up (8 to 52 weeks), these variables also obtained significant results, except depression and suicidal ideation. Regarding safety, there was no significant difference in safety phone calls for participants with suicidal ideation.
Conclusions
The evidence on suicide prevention app effectiveness is of low quality, precluding conclusive findings. Attempt reduction is suggested at 21 percent, but the confidence interval includes a potential 60 percent increase. Evidence on suicide-related psychological variables (suicide ideation, depression, hopelessness, and anxiety) is of higher quality (low–moderate), but effects are small and clinically uncertain. Safety findings are uncertain, impacting risk/benefit balance.
Cardiac rehabilitation (CR) with physical exercise is crucial for the secondary prevention of myocardial infarction and heart failure. However, according to published studies there are differences in access to hospital-based CR depending on sex, age, ethnicity, and geographical region. An alternative is CR in non-hospital settings such as primary care, the patient’s home, or another place by means of telerehabilitation.
Methods
We conducted a systematic review of full economic evaluations where non-hospital CR was compared with hospital CR in patients with ischemic heart disease or heart failure. Other eligibility criteria were model-based or clinical trial-based evaluations; studies reporting quality-adjusted life-years, years gained, or other clinical outcomes relevant to CR; and studies published in English or Spanish. Searches were conducted in June 2023 in various literature databases, including MEDLINE, Embase, CINAHL, Web of Science, INAHTA, PEDro, the Cost-Effectiveness Analysis Registry, and others. Study selection, data extraction, quality assessment, and evidence synthesis were conducted by one economist and checked by a second reviewer.
Results
Nine studies were selected from the 673 references identified. Another study was identified through previous systematic reviews. Ten randomized clinical trials were included in the review. None of the studies found differences in effectiveness between hospital CR and non-hospital CR. Two studies found that non-hospital CR was less costly than hospital CR, whereas the remainder did not find any differences in costs between the two groups or were unable to demonstrate the statistical significance of any differences observed. The best conducted studies concluded that non-hospital CR was as effective as and less costly than hospital CR.
Conclusions
Non-hospital CR was as cost effective as hospital CR for low- to-moderate risk patients. Based on the evidence, CR can be recommended in non-hospital settings. However, any form of CR should be evaluated after implementation because its complexity limits the generalizability of results across regions.
A consortium of five Spanish health technology assessment (HTA) agencies conducted the European Reference Networks Guidelines Programme for the development, appraisal, and implementation of clinical practice guidelines aiming to support clinical decision-making in the field of rare diseases (RDs). In response to this objective, methodologists and information specialists conducted systematic reviews (SRs). This study aims to explore the barriers/facilitators they encountered.
Methods
A survey was designed to elicit HTA agencies’ experience in developing SRs on RDs. Information was collected on the number of SRs conducted and the types of RDs and clinical questions addressed. In addition, they were asked to identify barriers and facilitators for each stage of the review (from the definition of PICO [population, intervention, comparator, outcome] components of the question to the issuing of recommendations). Finally, they were asked for process improvement suggestions. The survey was distributed by email and completed online. A thematic analysis was conducted to identify the issues identified at each stage of SR.
Results
A total of 111 SRs were conducted on 35 RDs. Most clinical questions were about diagnosis and treatment. The main barriers identified were lack of MesH (Medical Subject Headings) terms associated with the conditions, non-representative abstracts and keywords, lack of relevant information in the body of the articles, and reported data not allowing for quantitative syntheses or recommendations to be made. Facilitating aspects included Orphanet’s specific source of RD documents and having expert clinicians in the working groups who were also involved in all steps of the SR.
Conclusions
Conducting SRs in the field of RDs is challenging. Authors of primary studies are encouraged to be more exhaustive in reporting the results. More research focused on the SR methodology in RDs is necessary to address their particular characteristics and obtain robust results. It is crucial to collaborate with reference networks to address RDs, where the evidence is scarce.
Hand hygiene (HH) is the paramount measure used to prevent healthcare-associated infections. A repeated cross-sectional study was undertaken with direct observation of the degree of compliance on HH of healthcare personnel during the SARS-CoV-2 pandemic. Between, 2018–2019, 9,083 HH opportunities were considered, and 5,821 in 2020–2022. Chi squared tests were used to identify associations. The crude and adjusted odds ratios were used along with a logistic regression model for statistical analyses. Compliance on HH increased significantly (p < 0.001) from 54.5% (95% CI: 53.5, 55.5) to 70.1% (95% CI: 68.9, 71.2) during the COVID-19 pandemic. This increase was observed in four of the five key moments of HH established by the World Health Organization (WHO) (p < 0.05), except at moment 4. The factors that were significantly and independently associated with compliance were the time period considered, type of healthcare-personnel, attendance at training sessions, knowledge of HH and WHO guidelines, and availability of hand disinfectant alcoholic solution in pocket format. Highest HH compliance occurred during the COVID-19 pandemic, reflecting a positive change in healthcare-personnel’s behaviour regarding HH recommendations.
To investigate the occurrence of traumatic stress symptoms (TSS) among healthcare workers active during the COVID-19 pandemic and to obtain insight as to which pandemic-related stressful experiences are associated with onset and persistence of traumatic stress.
Methods
This is a multicenter prospective cohort study. Spanish healthcare workers (N = 4,809) participated at an initial assessment (i.e., just after the first wave of the Spain COVID-19 pandemic) and at a 4-month follow-up assessment using web-based surveys. Logistic regression investigated associations of 19 pandemic-related stressful experiences across four domains (infection-related, work-related, health-related and financial) with TSS prevalence, incidence and persistence, including simulations of population attributable risk proportions (PARP).
Results
Thirty-day TSS prevalence at T1 was 22.1%. Four-month incidence and persistence were 11.6% and 54.2%, respectively. Auxiliary nurses had highest rates of TSS prevalence (35.1%) and incidence (16.1%). All 19 pandemic-related stressful experiences under study were associated with TSS prevalence or incidence, especially experiences from the domains of health-related (PARP range 88.4–95.6%) and work-related stressful experiences (PARP range 76.8–86.5%). Nine stressful experiences were also associated with TSS persistence, of which having patient(s) in care who died from COVID-19 had the strongest association. This association remained significant after adjusting for co-occurring depression and anxiety.
Conclusions
TSSs among Spanish healthcare workers active during the COVID-19 pandemic are common and associated with various pandemic-related stressful experiences. Future research should investigate if these stressful experiences represent truly traumatic experiences and carry risk for the development of post-traumatic stress disorder.
Multilingualism in education consists in the teaching and learning of local majority languages, together with languages with an international status and new minority languages. Its long-standing history worldwide is rooted in colonialism, as well as the revitalization of indigenous languages. More recently, multilingual education worldwide has had to encompass English as ‘capital’ for the young generations, resulting in the use of English as a Lingua Franca (ELF) and English-Medium Instruction (EMI) for internationalization, in the era of computer-mediated communication. The changing nature of multingual education is the result of three driving forces: language per se, languages in society, and educational policies, as respectively reflected in the L3/Ln acquisition model encompassing transfer, the translanguaging model advocating heteroglossic practices against monoglossic, and the Continua of Language Education model. Research on primary, secondary, and tertiary education–level showcases the efficacy of well-planned multilingual education and the challenges of technology and informal multimodal learning.
Vitamin D is an essential nutrient to be consumed in the habitual dietary intake, whose deficiency is associated with various disturbances. This study represents a validation of vitamin D status estimation using a semi-quantitative FFQ, together with data from additional physical activity and lifestyle questionnaires. This information was combined to forecast the serum vitamin D status. Different statistical methods were applied to estimate the vitamin D status using predictors based on diet and lifestyle. Serum vitamin D was predicted using linear regression (with leave-one-out cross-validation) and random forest models. Intraclass correlation coefficients, Lin’s agreement coefficients, Bland–Altman plots and other methods were used to assess the accuracy of the predicted v. observed serum values. Data were collected in Spain. A total of 220 healthy volunteers aged between 18 and 78 years were included in this study. They completed validated questionnaires and agreed to provide blood samples to measure serum 25-hydroxyvitamin D (25(OH)D) levels. The common final predictors in both models were age, sex, sunlight exposure, vitamin D dietary intake (as assessed by the FFQ), BMI, time spent walking, physical activity and skin reaction after sun exposure. The intraclass correlation coefficient for the prediction was 0·60 (95 % CI: 0·52, 0·67; P < 0·001) using the random forest model. The magnitude of the correlation was moderate, which means that our estimation could be useful in future epidemiological studies to establish a link between the predicted 25(OH)D values and the occurrence of several clinical outcomes in larger cohorts.
While consonant acquisition clearly requires mastery of different articulatory configurations (segments), sub-segmental features and suprasegmental contexts influence both order of acquisition and mismatch (error) patterns (Bérubé, Bernhardt, Stemberger & Ciocca, 2020). Constraints-based nonlinear phonology provides a comprehensive framework for investigating the impact of sub- and suprasegmental impacts on acquisition (Bernhardt & Stemberger, 1998). The current study adopted such a framework in order to investigate these questions for Granada Spanish. Single-word samples of monolingual preschoolers in Granada (29 typically developing; 30 with protracted phonological development) were transcribed by native Spanish speakers in consultation with an international team. Beta regression analyses showed significant effects of age, developmental group, and word structure variables (word length, stress, position of consonants and syllables within the word); salience, markedness and/or frequency across the phonological hierarchy accounted for many patterns. The study further demonstrates the impacts of sub- and suprasegmental constraints of the phonological system on consonant acquisition.
La necesidad de mayor transparencia en las organizaciones no gubernamentales (ONG) ha llevado al propio sector a elaborar mecanismos de rendición de cuentas denominados mecanismos de autorregulación. Esta información debe estar al alcance público siendo Internet uno de los medios de comunicación más relevantes. En este contexto, el presente trabajo pretende, en primer lugar, ofrecer una comparación de las características de los mecanismos de autorregulación desarrollados por las ONG autorreguladoras de Latinoamérica con las de Estados Unidos y Europa; en segundo lugar, realizar un análisis comparativo del nivel de exigencia informativa en los mecanismos de autorregulación de tales ámbitos geográficos; y, en tercer lugar, el análisis empírico de factores que influyen en la demanda de transparencia informativa. Los principales resultados muestran que existen divergencias entre las ONG autorreguladoras estudiadas en cuanto al nivel de control de los mecanismos de autorregulación y ala exigencia informativa sobre el buen gobierno de la organización. El factor experiencia en la autorregulación es el aspecto que más influye en la demanda de transparencia.
Despite numerous reports on the beneficial effects of olive oil in the cardiovascular context, very little is known about the olive tree’s wild counterpart (Olea europaea, L. var. sylvestris), commonly known as acebuche (ACE) in Spain. The aim of this study was to analyse the possible beneficial effects of an extra virgin ACE oil on vascular function in a rodent model of arterial hypertension (AH) induced by NG-nitro-l-arginine methyl ester (L-NAME). Four experimental groups of male Wistar rats were studied: (1) normotensive rats (Control group); (2) normotensive rats fed a commercial diet supplemented with 15 % (w/w) ACE oil (Acebuche group); (3) rats made hypertensive following administration of L-NAME (L-NAME group); and (4) rats treated with L-NAME and simultaneously supplemented with 15 % ACE oil (LN + ACE group). All treatments were maintained for 12 weeks. Besides a significant blood pressure (BP)-lowering effect, the ACE oil-enriched diet counteracted the alterations found in aortas from hypertensive rats in terms of morphology and responsiveness to vasoactive mediators. In addition, a decrease in hypertension-related fibrotic and oxidative stress processes was observed in L-NAME-treated rats subjected to ACE oil supplement. Therefore, using a model of AH via nitric oxide depletion, here we demonstrate the beneficial effects of a wild olive oil based upon its vasodilator, antihypertensive, antioxidant, antihypertrophic and antifibrotic properties. We postulate that regular inclusion of ACE oil in the diet can alleviate the vascular remodelling and endothelial dysfunction processes typically found in AH, thus resulting in a significant reduction of BP.
Hepatitis A (HA) is a liver disease with a low mortality rate, but it can cause debilitating symptoms and fulminant hepatitis in some cases. Its incidence is greater in geographical areas with poor sanitation and hygiene. Spain is considered a low-endemicity country, so universal childhood immunization against HA is currently not financed by the National Health System. The aim of this study was to synthesize the scientific evidence on the cost effectiveness of universal childhood vaccination against HA.
Methods
Full economic evaluations, published in the English or Spanish languages, were included if they reported outcome measures related to the prevention of HA, adverse effects, or incremental cost-effectiveness ratios (ICERs). The Medline, Embase and Cochrane Library databases were searched for articles published from the beginning of the databases to April 2018.
Results
A total of 23 economic evaluations were included: one in a country of high endemicity, nine in countries of intermediate endemicity, and 13 in countries with low endemicity. Only one Spanish study, published in 1997, was found. Studies conducted in high- and intermediate- endemicity countries concluded that a universal childhood vaccination program against HA was a cost-effective option. However, in the case of countries with low endemicity the results were heterogeneous, although most agreed that a systematic vaccination strategy would not be a cost-effective option and that the adoption of such a strategy would not be justified given the limited benefits it would offer. The results of the economic evaluations depended on parameters such as the price and duration of the vaccine effect and the program coverage.
Conclusions
In countries with low endemicity the results were heterogeneous, although most studies concluded that the implementation of a universal vaccination strategy is not justified from the point of view of cost effectiveness.
The burden of depression is increasing worldwide, specifically in older adults. Unhealthy dietary patterns may partly explain this phenomenon. In the Spanish PREDIMED-Plus study, we explored (1) the cross-sectional association between the adherence to the Prime Diet Quality Score (PDQS), an a priori-defined high-quality food pattern, and the prevalence of depressive symptoms at baseline (cross-sectional analysis) and (2) the prospective association of baseline PDQS with changes in depressive symptomatology after 2 years of follow-up. After exclusions, we assessed 6612 participants in the cross-sectional analysis and 5523 participants in the prospective analysis. An energy-adjusted high-quality dietary score (PDQS) was assessed using a validated FFQ. The cross-sectional association between PDQS and the prevalence of depression or presence of depressive symptoms and the prospective changes in depressive symptoms were evaluated through multivariable regression models (logistic and linear models and mixed linear-effects models). PDQS was inversely associated with depressive status in the cross-sectional analysis. Participants in the highest quintile of PDQS (Q5) showed a significantly reduced odds of depression prevalence as compared to participants in the lowest quartile of PDQS (Q1) (OR (95 %) CI = 0·82 (0·68, 0·98))). The baseline prevalence of depression decreased across PDQS quintiles (Pfor trend = 0·015). A statistically significant association between PDQS and changes in depressive symptoms after 2-years follow-up was found (β (95 %) CI = −0·67 z-score (–1·17, −0·18). A higher PDQS was cross-sectionally related to a lower depressive status. Nevertheless, the null finding in our prospective analysis raises the possibility of reverse causality. Further prospective investigation is required to ascertain the association between PDQS and changes in depressive symptoms along time.
