Cryosurgery Versus Primary Androgen Deprivation Therapy for Locally Recurrent Prostate Cancer After Primary Radiotherapy: A Propensity-Matched Survival Analysis.
Background Optimal management of isolated local recurrence of prostate cancer after primary radiotherapy remains to be defined. Up-front androgen deprivation therapy (ADT) is widely used but may adversely affect the quality of life and is essentially a palliative treatment. Local salvage carries a different side-effect profile and is potentially curative, but it has not been compared to ADT. Materials and methods We conducted a propensity-matched analysis of cohorts of men treated with either whole gland cryotherapy (CRYO) or primary ADT following the diagnosis of locally recurrent prostate cancer. Our specific objectives were to compare overall survival (OS) and prostate cancer-specific mortality (PCSM) between CRYO vs. ADT. Results After a one-to-one matching, 169 patients from each cohort were included in comparisons. Median follow-up time was 6.7 years (ADT) vs. 18 years (CRYO). The 10-year PCSM was 18.5% (ADT) vs. 16.2% (CRYO), which was not statistically different [hazard ratioo (HR): 0.69, 95% CI: 0.36-1.34, p=0.27]. The median OS was 12.3 years (CRYO) versus 10.2 years (ADT) (HR: 0.63, 95% CI: 0.42-0.95, p=0.03). Conclusions While PCSM was similar between the two strategies, CRYO was associated with a longer OS compared to primary ADT. Given the retrospective nature of the trial, these results should be considered hypothesis-generating, and phase III trials comparing these two options are required to further explore these findings
Atypical functional connectivity during unfamiliar music listening in children with autism
Background: Atypical processing of unfamiliar, but less so familiar, stimuli has been
described in Autism Spectrum Disorder (ASD), in particular in relation to face processing.
We examined the construct of familiarity in ASD using familiar and unfamiliar songs,
to investigate the link between familiarity and autism symptoms, such as repetitive
behavior.
Methods: Forty-eight children, 24 with ASD (21 males, mean age = 9.96 years ± 1.54)
and 24 typically developing (TD) controls (21 males, mean age = 10.17 ± 1.90)
completed a music familiarity task using individually identified familiar compared to
unfamiliar songs, while magnetoencephalography (MEG) was recorded. Each song
was presented for 30 s. We used both amplitude envelope correlation (AEC) and the
weighted phase lag index (wPLI) to assess functional connectivity between specific
regions of interest (ROI) and non-ROI parcels, as well as at the whole brain level,
to understand what is preserved and what is impaired in familiar music listening in
this population.
Results: Increased wPLI synchronization for familiar vs. unfamiliar music was found
for typically developing children in the gamma frequency. There were no significant
differences within the ASD group for this comparison. During the processing of unfamiliar
music, we demonstrated left lateralized increased theta and beta band connectivity in
children with ASD compared to controls. An interaction effect found greater alpha band
connectivity in the TD group compared to ASD to unfamiliar music only, anchored in
the left insula.Conclusion: Our results revealed atypical processing of unfamiliar songs in children
with ASD, consistent with previous studies in other modalities reporting that processing
novelty is a challenge for ASD. Relatively typical processing of familiar stimuli may
represent a strength and may be of interest to strength-based intervention planning.info:eu-repo/semantics/publishedVersio
Can Motivation Normalize Working Memory and Task Persistence in Children with Attention-Deficit/Hyperactivity Disorder? The Effects of Money and Computer-Gaming
Visual-spatial Working Memory (WM) is the most impaired executive function in children with Attention-Deficit/Hyperactivity Disorder (ADHD). Some suggest that deficits in executive functioning are caused by motivational deficits. However, there are no studies that investigate the effects of motivation on the visual-spatial WM of children with- and without ADHD. Studies examining this in executive functions other than WM, show inconsistent results. These inconsistencies may be related to differences in the reinforcement used. The effects of different reinforcers on WM performance were investigated in 30 children with ADHD and 31 non-ADHD controls. A visual-spatial WM task was administered in four reinforcement conditions: Feedback-only, 1 euro, 10 euros, and a computer-game version of the task. In the Feedback-only condition, children with ADHD performed worse on the WM measure than controls. Although incentives significantly improved the WM performance of children with ADHD, even the strongest incentives (10 euros and Gaming) were unable to normalize their performance. Feedback-only provided sufficient reinforcement for controls to reach optimal performance, while children with ADHD required extra reinforcement. Only children with ADHD showed a decrease in performance over time. Importantly, the strongest incentives (10 euros and Gaming) normalized persistence of performance in these children, whereas 1 euro had no such effect. Both executive and motivational deficits give rise to visual-spatial WM deficits in ADHD. Problems with task-persistence in ADHD result from motivational deficits. In ADHD-reinforcement studies and clinical practice (e.g., assessment), reinforcement intensity can be a confounding factor and should be taken into account. Gaming can be a cost-effective way to maximize performance in ADHD
Brain Serotonin Synthesis in Adult Males Characterized by Physical Aggression during Childhood: A 21-Year Longitudinal Study
Adults exhibiting severe impulsive and aggressive behaviors have multiple indices of low serotonin (5-HT) neurotransmission. It remains unclear though whether low 5-HT mediates the behavior or instead reflects a pre-existing vulnerability trait.C-AMT bilaterally in the orbitofrontal cortex and self-reported more impulsiveness. Despite this, in adulthood there were no group differences in plasma tryptophan levels, genotyping, aggression, emotional intelligence, working memory, computerized measures of impulsivity, psychosocial functioning/adjustment, and personal and family history of mood and substance abuse disorders.These results force a re-examination of the low 5-HT hypothesis as central in the biology of violence. They suggest that low 5-HT does not mediate current behavior and should be considered a vulnerability factor for impulsive-aggressive behavior that may or may not be expressed depending on other biological factors, experience, and environmental support during development
