Objective: Acute anorexia nervosa (AN) leads to reduced gray (GM) and white matter (WM) volume in the brain, which however improves again upon restoration of weight. Yet little is known about the extent and clinical correlates of these brain changes, nor do we know much about the time-course and completeness of their recovery. Methods: We conducted a meta-analysis and a qualitative review of all magnetic resonance imaging studies involving volume analyses of the brain in both acute and recovered AN. Results: We identified structural neuroimaging studies with a total of 214 acute AN patients and 177 weight-recovered AN patients. In acute AN, GM was reduced by 5.6% and WM by 3.8% compared to healthy controls (HC). Short-term weight recovery 2–5 months after admission resulted in restitution of about half of the GM aberrations and almost full WM recovery. After 2–8 years of remission GM and WM were nearly normalized, and differences to HC (GM: –1.0%, WM: –0.7%) were no longer significant, although small residual changes could not be ruled out. In the qualitative review some studies found GM volume loss to be associated with cognitive deficits and clinical prognosis. Conclusions: GM and WM were strongly reduced in acute AN. The completeness of brain volume rehabilitation remained equivocal.

The auditory brainstem implant (ABI) is a surgically implanted device to electrically stimulate auditory neurons in the cochlear nucleus complex of the brainstem in humans to restore hearing sensations. The ABI is similar in function to a cochlear implant, but overall outcomes are poorer. However, recent applications of the ABI to new patient populations and improvements in surgical technique have led to significant improvements in outcomes. While the ABI provides hearing benefits to patients, the outcomes challenge our understanding of how the brain processes neural patterns of auditory information. The neural pattern of activation produced by an ABI is highly unnatural, yet some patients achieve high levels of speech understanding. Based on a meta-analysis of ABI surgeries and outcomes, a theory is proposed of a specialized sub-system of the cochlear nucleus that is critical for speech understanding.

<b><i>Introduction:</i></b> Stroke is defined as the lack of blood supply to the brain, leading to rapid loss of brain function presenting with impairments such as muscle weakness, spasticity, lack of coordination, and proprioception loss. Both hydrotherapy and land-based therapy aim to target these aspects in the process of rehabilitation. The study aims to determine the effectiveness of water-based therapy on balance and gait of patients with stroke compared to land-based therapy. <b><i>Methods:</i></b> Data for this review were extracted from databases such as CINAHL, OTseeker, Ovid, PEDro, and PubMed (MEDLINE) and other sources such as Google Scholar. PRISMA guidelines were followed to exclude irrelevant studies. Only randomized controlled trials (RCTs) were included, and methodological quality was assessed using the PEDro scale. A meta-analysis of extracted data was conducted. <b><i>Results:</i></b> A total of 16 relevant RCTs were included for the review (<i>n</i> = 412 participants). All RCTs investigated the effect of water-based therapy compared to land-based therapy on balance and gait of patients with stroke. Meta-analysis of studies that used the Berg Balance Scale (BBS) as a primary outcome measure favored land-based therapy. Studies that used the Good Balance System (GBS) and the Biodex Balance System (BioBS) to measure the changes in anteroposterior sway and mediolateral sway favored water-based therapy. The overall pooled effect favored land-based therapy in improving gait parameters. <b><i>Conclusion:</i></b> Findings from meta-analysis support the effectiveness of land-based therapy in the improvement of balance and gait parameters of patients with stroke. However, the evidence for water-based therapy continues to be limited, and higher quality studies are required to determine the effectiveness of water-based therapy on patients with stroke, particularly on balance and gait.

This multilevel meta-analysis examines whether emotional intelligence (EI) can be enhanced through training and identifies training effects’ determinants. We identified 24 studies containing 28 samples aiming at increasing individual-level EI among healthy adults. The results revealed a significant moderate standardized mean change between pre- and post-measurement for the main effect of EI training, and a stable pre- to follow-up effect. Additionally, the type of EI model, dimensions of the four branch model, length, and type of publication turned out to be significant moderators. The results suggest that EI trainings should be considered effective interventions.
