Purpose: To analyze the influence of abutment height (AH) on marginal bone loss (MBL). Materials and Methods: A literature search was performed for human studies (RCTs, prospective and retrospective cohorts) reporting on AH and MBL. The data obtained--including clinical outcomes, treatment covariates, and patient characteristics--were analyzed. Meta-regression was performed on the effect size of the differences between the shorter and larger AHs on the MBL of each study. The estimation was done using the restricted maximum likelihood method. Results: The initial screening and full-text analysis resulted in 7,936 and 46 articles, respectively. Finally, 14 articles were included in the systematic review, reporting a total of 1,606 implants. An overall high-to-moderate risk of bias was determined among the included investigations. Meta-regression analysis revealed that AH had a significant effect on MBL (b = --1.630, P < .003), demonstrating that longer abutments were correlated with less MBL. No effects were observed for the study type (P = .607), the number of stages (P = .510), or the elapsed time (P = .491). Conclusions: The height of the abutment has a significant impact on MBL. As such, increased AH is related to less MBL. Nevertheless, the role of confounding variables remains to be studied and determined. [ABSTRACT FROM AUTHOR]

Background: People with acquired brain injury (ABI) often have Social Cognition (SC) deficits. Impairment of SC causes the individual to have difficulties in daily functioning and can lead to social isolation. Research aimed at rehabilitation of SC in individuals with ABI is scarce and almost always addresses only one component of this ability. Objective: This pilot study aimed to assess the effectiveness of the new "SocialMind" program in improving all core components of SC in people with ABI. Method: The study included 31 participants with ABI, divided into experimental and control groups. The study spanned 44 weeks, involving an initial meeting, evaluation, training, and final assessment phases. The SocialMind program, structured into four modules, each with a duration of 30 h, targeted each SC component through tailored exercises. The program addressed emotion recognition, social awareness, ToM, and empathy. Results: The SocialMind group demonstrated significant improvements in emotion recognition (p = 0.017), social knowledge (p < 0.001), and empathy (p = 0.001) compared to the control group. ToM also showed a notable improvement that approached significance (p = 0.057). Conclusion: This pilot study suggests that the SocialMind program effectively enhances three of the four core components of SC in individuals with ABI. [ABSTRACT FROM AUTHOR]

We conducted an ambispective cohort study to assess the association between symptomatic radioulnar impingement syndrome (SRUIS) and distal radioulnar joint (DRUJ) salvage surgery to examine the influence of confounders on the final effect. The outcome variable was the incidence of SRUIS and the exposure variable was the surgical procedure. Seventy-two patients with median age of 48 years (IQR 25–78) were examined using bivariate and logistic regression multivariate analyses, and confounders were analysed in 15 multivariate models. Overall, SRUIS occurred in 21 patients (29%). Bivariate analysis showed a significant association between SRUIS and type of surgical procedure, observed in 71% after Sauvé–Kapandji, 50% after Bowers and 15% after Darrach procedure. When adjusted for age, aetiology and previous surgery, the significant association disappeared. Confounding is an important factor when accounting for SRUIS after DRUJ salvage surgery. The risk of SRUIS did not depend on the procedure, but rather on patient's age, aetiology and previous surgery. Level of evidence: II [ABSTRACT FROM AUTHOR]

Objective: To investigate whether a 20‐week aerobic and resistance exercise program induces changes in brain current density underlying working memory and inhibitory control in children with overweight/obesity. Methods: A total of 67 children (10.00 ± 1.10 years) were randomized into an exercise or control group. Electroencephalography (EEG)‐based current density (μA/mm2) was estimated using standardized low‐resolution brain electromagnetic tomography (sLORETA) during a working memory task (Delayed non‐matched‐to‐sample task, DNMS) and inhibitory control task (Modified flanker task, MFT). In DNMS, participants had to memorize four stimuli (Pokemons) and then select between two of them, one of which had not been previously shown. In MFT, participants had to indicate whether the centered cow (i.e., target) of five faced the right or left. Results: The exercise group had significantly greater increases in brain activation in comparison with the control group during the encoding phase of DNMS, particularly during retention of second stimuli in temporal and frontal areas (peak t = from 3.4 to 3.8, cluster size [k] = from 11 to 39), during the retention of the third stimuli in frontal areas (peak t = from 3.7 to 3.9, k = from 15 to 26), and during the retention of the fourth stimuli in temporal and occipital areas (peak t = from 2.7 to 4.3, k = from 13 to 101). In MFT, the exercise group presented a lower current density change in the middle frontal gyrus (peak t = −4.1, k = 5). No significant change was observed between groups for behavioral performance (p ≥ 0.05). Conclusion: A 20‐week exercise program modulates brain activity which might provide a positive influence on working memory and inhibitory control in children with overweight/obesity.

Anticipatory brain activity makes it possible to predict the occurrence of expected situations. However, events such as traffic accidents are statistically unpredictable and can generate catastrophic consequences. This study investigates the brain activity and effective connectivity associated with anticipating and processing such unexpected, unavoidable accidents. We asked 161 participants to ride a motorcycle simulator while recording their electroencephalographic activity. Of these, 90 participants experienced at least one accident while driving. We conducted both within‐subjects and between‐subjects comparisons. During the pre‐accident period, the right inferior parietal lobe (IPL), left anterior cingulate cortex (ACC), and right insula showed higher activity in the accident condition. In the post‐accident period, the bilateral orbitofrontal cortex, right IPL, bilateral ACC, and middle and superior frontal gyrus also showed increased activity in the accident condition. We observed greater effective connectivity within the nodes of the limbic network (LN) and between the nodes of the attentional networks in the pre‐accident period. In the post‐accident period, we also observed greater effective connectivity between networks, from the ventral attention network (VAN) to the somatomotor network and from nodes in the visual network, VAN, and default mode network to nodes in the frontoparietal network, LN, and attentional networks. This suggests that activating salience‐related processes and emotional processing allows the anticipation of accidents. Once an accident has occurred, integration and valuation of the new information takes place, and control processes are initiated to adapt behavior to the new demands of the environment.

Autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) are the most prevalent neurodevelopmental disorders. There is a growing body of literature investigating factors affecting quality of life in families (FQoL) with a child with these disorders. However, there are no studies that trace their knowledge anatomy. Thus, we conducted a scientometric analysis to describe this literature, detect certain variables that could be related to FQoL, and identify tendencies and open questions for future research. A literature search in the Web of Science, PubMed, and Scopus was run and identified 3281 publications published between 1975 and 2022. The results suggest an increase in the quantity of publications on FQoL in ASD and ADHD over the last few years (14% and 12%, respectively). For both research fields, the USA published the highest number of documents, showing that the production related to ADHD and FQoL is concentrated in just a few countries. Thematic analysis revealed several clusters, considering quality of life and children as core themes that are still setting trend lines. Moreover, it would be worthwhile to describe and analyze FQoL not only during the childhood of children with ASD and ADHD but also during their adolescence. IMPACT: Although the relationship between family quality of life and neurodevelopmental disorders could be considered novel, there is a growing interest from an interdisciplinary perspective. Family quality of life should be monitored not only during the childhood of children with ASD and ADHD, but also during their adolescence and adulthood. The analysis of the family quality of life in first-degree relatives and its relationship with protective factors (e.g., resilience and social support) should be explored in future studies., (© 2024.
