The relevance of cognitive performance during adolescence requires further studies that analyze potential associated factors. This study aimed to analyze inductive reasoning, reading comprehension, and mathematical thinking (problem-solving and number and calculation) in relation to sleep and depression in 244 students aged 12–17 years (47.6% boys and 52.4% girls). Daytime sleepiness, sleep quality, dysthymia, and euthymia (state and trait) were assessed by self-reported questionnaires. Moreover, correlations between these variables and cognitive performance, and differences depending on sociodemographic variables (sex, age, or academic year) were analyzed using non-parametric tests. Robust regression models were also conducted to evaluate the predictive role of significant variables on cognitive performance. The results showed significant bidirectional relationships between sleep- and depression-related variables, and between the latter ones and cognitive performance. Depression-trait was more related to cognitive performance than depression-state, and euthymia more than dysthymia, but neither daytime sleepiness nor sleep quality significantly correlated with it. As for sociodemographic variables, girls reported worse sleep and more depressive symptoms than boys did, and younger students reported better sleep but performed worse than the older ones. Although these findings should be further explored in forthcoming studies adding other promising variables, they highlight the importance of promoting euthymia to improve cognitive performance in adolescents.

BackgroundSleep problems are common and impairing in individuals with autism spectrum disorders (ASD). Evidence synthesis including both subjective (ie, measured with questionnaires) and objective (ie, quantified with neurophysiological tools) sleep alterations in youth with ASD is currently lacking.ObjectiveWe conducted a systematic review and meta-analysis of subjective and objective studies sleep studies in youth with ASD.MethodsWe searched the following electronic databases with no language, date or type of document restriction up to 23 May 2018: PubMed, PsycInfo, Embase+Embase Classic, Ovid Medline and Web of Knowledge. Random-effects models were used. Heterogeneity was assessed with Cochran’s Q and I2 statistics. Publication (small studies) bias was assessed with final plots and the Egger’s test. Study quality was evaluated with the Newcastle Ottawa Scale. Analyses were conducted using Review Manager and Comprehensive Meta-Analysis.FindingsFrom a pool of 3359 non-duplicate potentially relevant references, 47 datasets were included in the meta-analyses. Subjective and objective sleep outcome measures were extracted from 37 and 15 studies, respectively. Only five studies were based on comorbidity free, medication-naïve participants. Compared with typically developing controls, youth with ASD significantly differed in 10/14 subjective parameters and in 7/14 objective sleep parameters. The average quality score in the Newcastle-Ottawa Scale was 5.9/9.Discussion and clinical implicationsA number of subjective and, to a less extent, objective sleep alterations might characterise youth with ASD, but future studies should assess the impact of pharmacological treatment and psychiatric comorbidities.

BackgroundThe efficacy of meditation-based therapies for attention deficit/hyperactivity disorder (ADHD) across the lifespan remains uncertain.ObjectiveTo conduct a systematic review and meta-analysis of randomised controlled trials (RCTs) assessing the efficacy of meditation-based therapies for ADHD core symptoms and associated neuropsychological dysfunctions in children/adolescents or adults with ADHD.MethodsWe searched Pubmed, PsycInfo, Embase+Embase Classic, Ovid Medline and Web of Knowledge with no language, date or type of document restriction, up to 5 May 2018. Random-effects model was used. Heterogeneity was assessed with Cochran’s Q and I2 statistics. Publication (small studies) bias was assessed with funnel plots and the Egger’s test. Studies were evaluated with the Cochrane risk of bias (RoB) tool. Analyses were conducted using Comprehensive Meta-Analysis.Findings13 RCTs (seven in children/adolescents, n=270 and six in adults, n=339) were retained. Only one RCT was double-blind.Meditation-based therapies were significantly more efficacious than the control conditions in decreasing the severity of ADHD core symptoms (inattention+hyperactivity/impulsivity: children/adolescents: Hedge’s g=-0.44, 95% CI −0.69 to −0.19, I20%; adults: Hedge’s g=−0.66, 95% CI –1.21 to −0.11, I281.81%). No significant effects were found on neuropsychological measures of inattention and inhibition in children/adolescents. In adults, significant effects were detected on working memory and inhibition, although these results were based on a small number of studies (n=3). 57% and 43% of the studies in children/adolescents were rated at overall unclear and high risk of bias, respectively. In adults, 33% and 67% of the studies were deemed at overall unclear and high risk of bias, respectively. No evidence of publication bias was found.ConclusionsDespite statistically significant effects on ADHD combined core symptoms, due to paucity of RCTs, heterogeneity across studies and lack of studies at low risk of bias, there is insufficient methodologically sound evidence to support meditation-based therapies for ADHD.Trial registration numberPROSPERO 2018 [CRD42018096156].

This study aimed to determine the extent to which caregivers of patients with chronic illnesses experience death anxiety, and which variables from caregivers and patients might potentially be related to their death anxiety. It also aimed to compare the levels of death anxiety between patients and caregivers. Web of Science, Scopus, PubMed, Psychology Database, Cochrane, and Google Scholar were searched for original studies available until December 2022 that quantitatively addressed death anxiety in family and informal caregivers of individuals with chronic illnesses. The methodological quality of the included studies was assessed, and a meta-analysis was conducted using Hedges’ g as the effect size index and the DerSimonian–Laird method to analyze differences between patients and caregivers in death anxiety. The results of the 11 included studies showed moderate levels of death anxiety in caregivers, and the meta-analysis (k = 7; 614 patients and 586 caregivers) revealed non-significant differences between the death anxiety experienced by patients and caregivers (pooled Hedges’ g = −0.03, 95% CI = −0.29 to 0.25, p = 0.802). Some sociodemographic and psychological factors (e.g., gender, depression, and anxiety) might be related to the death anxiety experienced, but additional research is necessary to validate these findings.

To examine subjective and objective sleep patterns in children with different Attention-Deficit/Hyperactivity Disorder (ADHD) presentations. Method: We assessed 92 children diagnosed with ADHD (29 ADHD-Inattentive [ADHD-I], 31 ADHD-Hyperactive/Impulsive [ADHD-H/I], and 32 ADHD-Combined [ADHD-C)]) aged 7–11 years. The Pediatric Sleep Questionnaire (PSQ), Pediatric Daytime Sleepiness Scale (PDSS), and a sleep diary were used as subjective sleep measures, and polysomnography was used to objectively assess sleep quantity, quality, and fragmentation. Results: Subjective data showed impaired sleep in 12.7% of the sample. No significant differences were found between ADHD presentations in any objective and subjective sleep variable. Nevertheless, data on sleep fragmentation suggested a worse sleep continuity for the ADHD-H/I group, and correlation analyses confirmed that sleep is affected by age. Conclusions: Children with ADHD may suffer from sleep breathing problems and daytime sleepiness, as reported by their parents, even when their total sleep time and sleep efficiency are not affected. It seems that sleep in this population does not largely vary as a function of the ADHD presentation. Sleep in children with ADHD evolves with age. Examinar los patrones de sueño subjetivos y objetivos de niños con diferentes presentaciones del Trastorno por déficit de atención e hiperactividad (TDAH). Método: Se evaluaron 92 niños (29 TDAH-inatento [TDAH-I)], 31 TDAH-hiperactivo/impulsivo [TDAH-H/I] y 32 TDAH-combinado [TDAH-C]) de entre 7–11 años. El Pediatric Sleep Questionnaire (PSQ), la Pediatric Daytime Sleepiness Scale (PDSS) y un diario de sueño se utilizaron como medidas subjetivas de sueño. Para evaluar objetivamente la cantidad, calidad y fragmentación del sueño se utilizó la polisomnografía. Resultados: Los datos subjetivos mostraron alteraciones del sueño en el 12,7% de la muestra. No se observaron diferencias significativas en ninguna variable objetiva y subjetiva de sueño entre las diferentes presentaciones de TDAH. No obstante, los datos de fragmentación de sueño sugirieron una peor continuidad en el grupo con TDAH-H/I, y los análisis correlacionales confirmaron que el sueño se ve afectado por la edad. Conclusiones: Los niños con TDAH pueden experimentar problemas respiratorios durante el sueño y somnolencia diurna, según lo informado por sus padres, incluso cuando su tiempo total y eficiencia de sueño no se vean afectados. Parece que el sueño en el TDAH no varía en función de la presentación. El sueño en los niños con TDAH evoluciona con la edad.

Obesity is a major risk factor for obstructive sleep apnoea (OSA), the most common sleep-disordered breathing related to neurocognitive and metabolic syndromes, type II diabetes, and cardiovascular diseases. Although strongly recommended for this condition, there are no studies on the effectiveness of an interdisciplinary weight loss and lifestyle intervention including nutrition, exercise, sleep hygiene, and smoking and alcohol cessation. INTERAPNEA is a randomised controlled trial with a two-arm parallel design aimed at determining the effects of an interdisciplinary tailored weight loss and lifestyle intervention on OSA outcomes. The study will include 84 males aged 18–65 with a body mass index of ≥25 kg/m2 and severe to moderate OSA randomly assigned to usual care (i.e., continuous positive airway pressure), or interdisciplinary weight loss and lifestyle intervention combined with usual care. Outcomes will be measured at baseline, intervention end-point, and six-month post-intervention, including apnoea-hypopnoea index (primary outcome), other neurophysical and cardiorespiratory polysomnographic outcomes, sleep quality, daily functioning and mood, body weight and composition, physical fitness, blood biomarkers, health-related quality of life, and cost-effectiveness. INTERAPNEA may serve to establish a cost-effective treatment not only for the improvement of OSA and its vast and severe comorbidities, but also for a potential remission of this condition.

Purpose of Review The aim of this systematic rewiew (SR) was to evaluate the effects of strength exercises (SE) on pain and quality of life (QoL) in subjects with systemic peripheral neuropathies (PN) in comparison with other exercise modalities and other conventional/control treatments. Sixteen studies ( n  = 1150) were included in the SR and fourteen were analyzed in the meta-analysis. Recent Findings SE produced a significant improvement in pain intensity in 81.25% of the studies included (weighted Hedges’g =  − 0.57, 95% IC =  − 0.89 to − 0.24, p  < 0.001) but showing large heterogeneity values (I2 = 87.09%). Four of ten studies that measured QoL also reported significant improvements. Summary These findings suggest that SE could be an effective treatment on pain in subjects with systemic PN, especially in the long term. Programs lasting at least 8-12 weeks and taking values between 30%-65% of 1RM are suggested as appropriate options. Improvements in QoL due to SE remain unclear.

Research Ranking of Spanish Public Universities (2019). The changes produced in the Spanish university system due to the Bologna process require periodically updated evaluation reports of research activity. The objective of this study is to update the last available ranking of Spanish public universities, based on data from 2013-2018. The production and productivity of each university were assessed based on seven specific indicators and a global score: articles in journals indexed in the JCR (Journal Citation Reports), research periods, R+D projects, doctoral theses, FPU (training of university professors) grants, FPI (training of personal researchers) grants, and patents. Globally, the universities Complutense of Madrid, Barcelona, and Granada hold the first positions in terms of production, while the first positions in terms of productivity are held by the universities Pompeu Fabra, Autonomous of Madrid, and Autonomous of Barcelona. The universities that hold the top positions in this ranking remain relatively steady over time and are also the Spanish universities that stand out in international classifications.

La incidencia y gravedad de los filicidios, junto a la alta conmoción social y repercusión mediática que producen, demandan investigaciones que faciliten la prevención de estos delitos. El objetivo de esta revisión sistemática ha sido analizar la existencia o no de características comunes entre los varones filicidas de menores de 18 años, atendiendo a diversos factores personales y contextuales, como el grado de parentesco, trastornos mentales o comisión de suicidio a posteriori. A través de una búsqueda exhaustiva en Web of Science, Pubmed, Scopus y ProQuest se obtuvieron 8,698 resultados, siendo incluidos 23 estudios tras la aplicación de los criterios de inclusión y calidad. Los resultados sugieren que los filicidas comparten ciertas características conductuales y contextuales, aunque algunas de ellas dependen del grado de parentesco con la víctima. Sin embargo, se requieren más estudios que analicen indicadores comunes o diferenciales de los varones filicidas para poder diseñar estrategias de prevención específicas.

Background: To mitigate the spread of the coronavirus disease (COVID-19) pandemic, governments around the world adopted exceptional lockdown measures. This led to the disruption of normal life routines, including sleep. The aim of this study was to analyze differences in sleep patterns and subjective variables of sleep quality before and during lockdown. Methods: A sample of 1673 Spanish adults (30% men; 82% of the total were between 21 and 50 years of age) was evaluated. The following sleep variables were evaluated: Sleep latency, sleep time, number and duration of awakenings, sleep satisfaction, daytime sleepiness, and the manifestation of symptoms related to sleep problems. Results: Although 45% of people changed their sleep schedules (resulting in 42% sleeping longer during lockdown), sleep quality (37.6% worse), daytime sleepiness (28% worse), number of awakenings (36.9% more), and duration of awakenings (45% longer) were markedly worse. Statistical analyses indicated significant differences in all the evaluated sleep variables before and during lockdown in both men and women. Women reported less sleep satisfaction, and more symptoms related to sleep problems than men. Conclusions: A deterioration in the sleep patterns of the Spanish population, especially women, because of the lockdown declared due to the COVID-19 pandemic.
