The effect of learning to drum on behavior and brain function in autistic adolescents

This current study aimed to investigate the impact of drum training on behavior and brain function in autistic adolescents with no prior drumming experience. Thirty-six autistic adolescents were recruited and randomly assigned to one of two groups. The drum group received individual drum tuition (two lessons per week over an 8-wk period), while the control group did not. All participants attended a testing session before and after the 8-wk period. Each session included a drumming assessment, an MRI scan, and a parent completing questionnaires relating to the participants’ behavioral difficulties. Results showed that improvements in drumming performance were associated with a significant reduction in hyperactivity and inattention difficulties in drummers compared to controls. The fMRI results demonstrated increased functional connectivity in brain areas responsible for inhibitory control, action outcomes monitoring, and self-regulation. In particular, seed-to-voxel analyses revealed an increased functional connectivity in the right inferior frontal gyrus and the right dorsolateral prefrontal cortex. A multivariate pattern analysis demonstrated significant changes in the medial frontal cortex, the left and right paracingulate cortex, the subcallosal cortex, the left frontal pole, the caudate, and the left nucleus accumbens. In conclusion, this study investigates the impact of a drum-based intervention on neural and behavioral outcomes in autistic adolescents. We hope that these findings will inform further research and trials into the potential use of drum-based interventions in benefitting clinical populations with inhibition-related disorders and emotional and behavioral difficulties.

Autism spectrum disorder (ASD) is a lifelong neurodevelopmental disorder characterized by deficits in social communication and social interactions as well as a range of restricted, repetitive interests, activities, and behaviors (1). Over recent decades, incidence estimates for ASD have increased (2), with a prevalence of 1 in 59 children in the United States (3) and over 600,000 people in the United Kingdom, which is equivalent to a population prevalence of ∼1% (4, 5). In this context of increased autism prevalence, there is an existing need to develop interventions that offer new insights and perspectives and help address the specifically high demand for services for autistic adolescents and young adults (6). [The term “autistic” is used throughout this paper because of a large percentage of the UK autism community’s preference for the identity-first construction (e.g., “autistic person”) over the person-first phrase (e.g., “person with autism”) (7).] Indeed, autistic young people often face discontinuity in care provision in the transitionary period from child and adolescent services to adult services, just when their care needs are most pressing, making their transition into adulthood particularly difficult (8). In particular, mismatches across services, such as differences in eligibility criteria or age cutoffs, mean that many autistic young adults fall through the care gap after exiting high school (8). Autistic individuals are particularly vulnerable during this period because they often face high unemployment rates, increased levels of comorbid psychiatric diagnoses such as anxiety and depression, and, more broadly, greater reliance on assistance from others when it comes to carrying out adulthood-related daily activities (9–11).A growing body of research suggests that key social domains of the ASD symptomatology may be related to atypical executive functioning (12, 13). Inhibitory control, one of the core executive functions (EFs), corresponds to the ability to delay the onset of behavioral responses, or withhold behaviors that are prepotent but contextually inappropriate (14, 15). It works in concert with other EFs, such as cognitive flexibility and working memory, to exert top-down control on behavioral responses, enable self-regulation, and help navigate social relationships, therefore supporting transition into adulthood and independent living (16, 17). More specifically, it is thought that atypical inhibitory control in autism may underlie significant strengths but may also exacerbate key features of the ASD symptomatology, such as struggling with change and uncertainty, or having difficulty interpreting social cues (18–21). Impaired performance on inhibitory control tasks is frequent in autistic individuals (12, 13, 22, 23). In particular, it has been associated with severe restricted and repetitive behaviors (19, 24, 25), as well as a deficit in proactive response slowing [the ability to slow the initiation of a behavioral response in preparation for stopping during conditions of uncertainty (19)]. At the neuroimaging level, prior studies have revealed atypical recruitment of frontal regions in autistic adolescents (20), and impaired functional connectivity (FC) of the inferior frontal junction, key regions for inhibitory control, in autistic children (26).Autistic individuals often report being preoccupied with certain topics (27) and struggling with anxiety and anger management (28, 29). In a study by Van Hees et al. (30), higher-education autistic students described feeling overwhelmed by the demands placed on them while facing significant difficulties with planning, information processing, time management, organizational skills, and sensory overload. These difficulties may reflect impaired attention and inhibition abilities, complementary processes that allow individuals to pursue the achievement of a particular goal while remaining flexibly responsive to environmental demands (21, 31). A research study on a population-based twin sample of 17,000 children (9 y to 12 y old) concluded that the vast majority of children with ASD traits also exhibit cooccurring attention deficit and hyperactivity disorder (ADHD) traits (32). More specifically, the authors demonstrated that 82% of the boys and 95% of the girls with high ASD traits on all three ASD domains (social impairments, communication impairments, and restricted repetitive behaviors and interests) exhibited difficulties on at least one of the three ADHD domains (attentional difficulties, hyperactivity, and impulsivity). Additionally, they reported that repetitive and restricted behaviors in ASD correlated with ADHD domains, particularly with impulsivity and attentional difficulties. This is in line with a previous twin study in adults, which reported the highest phenotypic and genetic overlap between ADHD traits and “nonsocial” autistic-like traits such as attention switching difficulties (33).Music has long been known to promote cognitive and emotional wellbeing in both clinical and healthy populations (34, 35). Rhythm-based musical training, in particular, has been shown to enhance higher-order cognition and motor control (31). There is growing evidence that activities designed to improve beat synchronization skills may provide an effective approach to developing neurological processes that underpin self-regulation and EF skills (36). Indeed, EF deficits have been linked with poor rhythm perception in children (37) and poor sensorimotor synchronization in young adults (38). Using the Integrated Visual and Auditory Plus Continuous Performance Test (39), Slater et al. (31) highlighted that drumming practice is associated with better scores in inhibitory control and selective attention in adult percussionists compared to nonmusicians.More specifically, learning to drum requires error monitoring and temporal accuracy and therefore both attentional and inhibitory control (31, 40). In a recent study, Lowry et al. (40) used a mixed-methods analysis to investigate behavioral changes in children with emotional and behavioral difficulties, after learning to drum. Following drum training, the participants displayed enhanced attentional focus and reduced hyperactivity and peer problems (40). These results concur with Draper et al.’s (41) recent findings showing that drumming improves motor control and attentional focus and reduces emotional and peer problems in autistic children. It is important to note that motor control is particularly relevant in the context of ASD. Indeed, recent studies have consistently demonstrated motor impairments across the autism spectrum (42, 43), including gross and fine motor difficulties (44, 45) and delays with motor planning (46). Sokhadze et al. (47) showed that ∼80% of autistic individuals also present with clumsiness or motor dyspraxia, which can manifest as having difficulty with motor coordination as well as concentration, planning, and organization. These difficulties may impact the individual’s ability to carry out daily activities, which, in turn, can lead to rejection from peers and social isolation (48). Similarly, motor impairments in balance, motor accuracy, and object manipulation scores have been reported to be predictive of social dysfunction in young autistic boys (49). In this context, learning to drum could be regarded as particularly beneficial because it involves not only musicality but also the development of multimodal skills such as body coordination, sensorimotor integration, and cardiovascular exercise processes (50). Additionally, it is appealing and accessible to everyone regardless of age, gender, ethnicity, or musical background (51, 52).In our proof-of-concept study, Amad et al. (53) showed that the brain is capable of neuroplastic modifications through drum-based practice in neurotypical adolescents. In particular, changes in FC were observed post drum training in brain regions known to exhibit atypical functioning in autism, such as areas associated with motor skills and the mirror neuron system.In the present study, we investigated the impact of drum training on brain function in 36 autistic adolescents who were split into two age- and gender-matched groups: a drum group (n = 19), who were evaluated before and after learning to drum, and a control group (n = 17), who were also evaluated longitudinally but with no intervention. We explored behavioral outcomes related to drum practice in this clinical population and examined their association with changes in FC between the two groups (i.e., drum group vs. control group) over time (i.e., before vs. after drum training).We hypothesized that drumming performance would improve in the drum group over time, while no improvement would be observed in the control group. Furthermore, we hypothesized that changes in hyperactivity, attentional difficulties, problem behaviors, and repetitive and restricted behaviors would be observed in the drum group. We also hypothesized that cooccurring changes in FC in brain areas responsible for attentional focus and inhibitory control would be identified following drum training.     

Very Low Alcohol Consumption Is Associated with Lower Prevalence of Cirrhosis and Hepatocellular Carcinoma in Patients with Non-Alcoholic Fatty Liver Disease

The role of moderate alcohol consumption in the evolution of NAFLD is still debated. The aim of this study is to evaluate the impact of current and lifelong alcohol consumption in patients with NAFLD. From 2015 to 2020, we enrolled 276 consecutive patients fulfilling criteria of NAFLD (alcohol consumption up to 140 g/week for women and 210 g/week for men). According to their current alcohol intake per week, patients were divided in: abstainers, very low consumers (C1: <70 g/week) and moderate consumers (C2). We created a new tool, called LACU (Lifetime Alcohol Consuming Unit) to estimate the alcohol exposure across lifetime: 1 LACU was defined as 7 alcohol units per week for 1 drinking year. Patients were divided into lifelong abstainers and consumers and the latter furtherly divided into quartiles: Q1-Q4. Stratification according to alcohol intake, both current and cumulative as estimated by LACU, showed that very low consumers (C1 and Q1-Q3) displayed lower frequency of cirrhosis and hepatocellular carcinoma compared to abstainers and moderate consumers (C2 and Q4). We can speculate that up to one glass of wine daily in the context of a Mediterranean diet may be a long-term useful approach in selected NAFLD patients.

Complete Pathologic Response after Combined Modality Treatment for Rectal Cancer and Long-Term Survival: A Meta-Analysis

Background

Complete pathologic response (CPR) after neoadjuvant chemoradiotherapy (combined modality treatment, CMT) for rectal cancer seems associated with improved survival compared to partial or no response (NPR). However, previous reports have been limited by small sample size and single-institution design.

Methods

A systematic literature review was conducted to detect studies comparing long-term results of patients with CPR and NPR after CMT for rectal cancer. Variables were pooled only if evaluated by 3 or more studies. Study end points included rates of CPR, local recurrence (LR), distant recurrence (DR), 5-year overall survival (OS), and disease-free survival (DFS).

Results

Twelve studies (1,913 patients) with rectal cancer treated with CMT were included. CPR was observed in 300 patients (15.6%). CPR and NPR patient groups were similar with respect to age, sex, tumor size, distance of tumor from the anus, and stage of disease before treatment. Median follow-up ranged from 23 to 46?months. CPR patients had lower rates of LR [0.7% vs. 2.6%; odds ratio (OR) 0.45, 95% confidence interval (CI) 0.22?C0.90, P?=?0.03], DR (5.3% vs. 24.1%; OR 0.15, 95% CI 0.07?C0.31, P?=?0.0001), and simultaneous LR?+?DR (0.7% vs. 4.8%; OR 0.32, 95% CI 0.13?C0.79, P?=?0.01). OS was 92.9% for CPR versus 73.4% for NPR (OR 3.6, 95% CI 1.84?C7.22, P?=?0.002), and DFS was 86.9% versus 63.9% (OR 3.53, 95% CI 1.62?C7.72, P?=?0.002).

Conclusions

CPR after CMT for rectal cancer is associated with improved local and distal control as well as better OS and DFS.     

Analysis of survival after pancreatic resection for oncological pathologies

Surgical treatment of pancreatic cancer is to date the only modality that offers a chance of long-term survival. Potentially curative surgery is an option for only about 15% of patients with pancreatic adenocarcinoma. The aim of this study was to determine the survival and to assess the association of clinical, pathological, and treatment features with survival of patients who underwent resection of pancreatic cancer at the Department of Surgery of Udine University Hospital. From November 1989 to December 2005, 137 consecutive patients, who underwent surgical procedures for pancreatic cancer, were followed in our department. We performed 76 pancreatico-duodenectomy, 26 distal pancreatectomies and 35 total pancreatectomies. The surgical reconstruction after pancreatico-duodenectomy was as follows: 11 closures of the main duct with manual nonabsorbable stitches, 24 closures of the main duct with a linear stapler, 17 occlusions of the main duct with neoprene glue and 24 duct-to-mucosa anastomoses. Mean survival time was 27.7 +/- 26.93 months (mean +/- SD) and mean disease-free survival time was 25.4 +/- 23.06 months (mean +/- SD). 1, 3, 5, 7 and 9-year survival rates were 63.9, 33.7, 21.17, 12.7 and 10.2%, respectively. Significant differences in survival were recorded by the Log-rank test for age > 70 (p = 0.001), surgical procedures (p = 0.00046) and presence of metastases (p = 0.0055) The treatment of pancreatic cancer is undertaken with two different aims. The first is radical surgery for patients with early-stage disease, mainly stage I and partly stage II. In all other cases, the aim of treatment is the palliation of the several distressing symptoms related to this cancer. The standard treatment option for resectable tumours is radical pancreatic resection according to the Whipple procedure or total pancreatectomy.     

Association between trauma and cancer of the testis: the importance of self-palpation of the testis for the early detection: two case reports

introduction: Cancer of the testis is not always early detected and recognised, both by the physician and by the patient: sometimes physicians do not make an accurate genitals exam while patients often underestimate this problem. Case reports: Case I: 42-year-old man accepted from another hospital's Emergency, because of pain and edema of the right testis after a recent trauma on the gonad. At US, evidence of increased volume of the right testis with a large intraparenchymal hematoma. The markers were higher than normal. We performed a right orchiecthomy. The pathologist noted the presence of a mixed cancer of the testis (95% embryonal, 5% seminoma). Case II: 49-year-old man with hematuria, accepted from Emergency. The abdominal US revealed the presence of a voluminous neoformation (diameter of 12 cm) of the right kidney with neoplastic thrombosis of the right kidney vein. At the general physical exam, we detected the presence of an increased right testis, that at the US appared to be suspicious for cancer. Tumor markers were normal with the exception of αFP. We performed right nephro-adrenalectomy, right orchiectomy and removal of local nodes. The definitive histological examination demonstrated the presence of a seminoma of the testis and papillary carcinoma of the kidney with node metastasis. Discussion: Current studies showed an association between trauma and cancer of the testis, even if some authors did not find this association because they consider that patients with trauma undergo US and in that occasion cancer is incidentally detected. Conclusions: The association between trauma and cancer of the testis is controversial in current studies. Furthermore screening for the cancer of the testis does not seem to be useful, even if the self- and the physician's palpation of the testis seem to be very important because in these two cases they should allow the early detection of the condition, with a resulting better prognosis.     

Is proliferative colonic disease presentation changing?

AIM: To compare the site, age and gender of cases of colorectal cancer (CRC) and polyps in a single referral center in Rome, Italy, during two periods.METHODS: CRC data were collected from surgery/pathology registers, and polyp data from colonoscopy reports. Patients who met the criteria for familial adenomatous polyposis, hereditary non-polyposis colorectal cancer syndrome or inflammatory bowel disease were excluded from the study. Overlap of patients between the two groups (cancers and polyps) was carefully avoided. The χ² statistical test and a regression analysis were performed.RESULTS: Data from a total of 768 patients (352 and 416 patients, respectively, in periods A and B) who underwent surgery for cancer were collected. During the same time periods, a total of 1693 polyps were analyzed from 978 patients with complete colonoscopies (428 polyps from 273 patients during period A and 1265 polyps from 705 patients during period B). A proximal shift in cancer occurred during the latter years for both sexes, but particularly in males. Proximal cancer increased > 3-fold in period B compared to period A in males [odds ratio (OR) 3.31, 95%CI: 2.00-5.47; P < 0.0001). A similar proximal shift was observed for polyps, particularly in males (OR 1.87, 95%CI: 1.23-2.87; P < 0.0038), but also in females (OR 1.62, 95%CI: 0.96-2.73; P < 0.07).CONCLUSION: The prevalence of proximal proliferative colonic lesions seems to have increased over the last decade, particularly in males.
