Long-term effects of transcranial direct current stimulation in the treatment of autism spectrum disorder: A randomized controlled trial.

AIM: To compare the efficacy of 0, 5, and 20 sessions of transcranial direct current stimulation (tDCS) for reducing symptoms of autism spectrum disorder (ASD). METHOD: Thirty-six male children with ASD (mean age 2 years 3 months, SD 4 months, age range 1 years 6 months-2 years 11 months) were balanced and stratified by age, sex, and baseline severity of ASD, to: (1) a control group that received 20 sessions of sham tDCS; (2) a 5-session tDCS group (5-tDCS) that received 5 sessions of active tDCS followed by 15 sessions of sham tDCS; and (3) a 20-session tDCS group (20-tDCS) that received 20 sessions of active tDCS. All groups participated in the special school activity of Khon Kaen Special Education Center, Thailand. The primary outcome was autism severity as measured by the Childhood Autism Severity Scale. RESULTS: The 5-tDCS and 20-tDCS groups evidenced greater reductions in autism severity than the control group at days 5 and 14, and months 6 and 12. There were no significant differences in the outcome between the 5- and 20-tDCS groups at any time point. Within-group analysis showed clinically meaningful improvements starting at month 6 for the participants in the control group, and clinically meaningful improvements starting on day 5 in both active tDCS groups, all of which were maintained to month 12. INTERPRETATION: The 5- and 20-session tDCS seems to reduce autism severity faster than sham tDCS. These effects maintained at least for 1 year. WHAT THIS PAPER ADDS: Twenty sessions of transcranial direct current stimulation (tDCS) were not superior to five sessions. Sham tDCS with a special school activity can reduce autism severity starting at 6 months after treatment. The benefits observed for 5 and 20 sessions of tDCS last for at least 12 months.

Frequency of Operative Anesthesia Care After Traumatic Injury.

BACKGROUND: Virtually all anesthesiologists care for patients who sustain traumatic injuries; however, the frequency with which operative anesthesia care is provided to this specific patient population is unclear. We sought to better understand the degree to which anesthesia providers participate in operative trauma care and how this differs by trauma center designation (levels I-V), using data from a comprehensive, regional database-the Washington State Trauma Registry (WSTR). We also sought to specifically assess operative anesthesia care frequency vis a vis the American College of Surgeons guidelines for continuous anesthesiology coverage for Level II trauma center accreditation. METHODS: We conducted a retrospective analysis measuring the frequency of operative anesthesia care among patients enrolled in the WSTR. Univariate comparisons were made between trauma patients who had surgery during their admission and those who did not (medical management only). In addition, clinical factors associated with surgical intervention were measured. We also measured the average times from hospital admission to surgery and compared these times across trauma centers, grouped level I, II, and III-V. RESULTS: From 2004 to 2014, there were approximately 176,000 encounters meeting WSTR inclusion criteria. Approximately 60% of these trauma encounters included exposure to operative anesthesia during the admission. Among all surgical procedures during the trauma admission, approximately 33% occurred within a level I trauma center, 23% occurred within a level II trauma center, and 44% occurred in a trauma center with a III, IV, or V designation. The predominant procedure category during a trauma admission was orthopedic. The presence of hypotension on admission (P < .01), increasing injury severity score (P < .01) and higher emergency department Glasgow Coma Score (P < .01) were all associated with surgical intervention during the trauma hospitalization, after adjustment for potential confounders. In level I trauma centers, for general surgical procedures, the median time to surgery was 2.5 hours; in level II trauma centers, the median time was 1.7 hours. CONCLUSIONS: This study highlights the frequent role anesthesiologists play in caring for patients who sustain traumatic injuries, in trauma centers levels I-V. In level II trauma centers, in-house anesthesiology coverage might have benefit for those patients requiring surgery within 1 hour, whereas the former American College of Surgeons requirement of 30-minute response time for out-of-hospital anesthesiology coverage is likely sufficient to provide satisfactory care to patients requiring surgery within 3 hours. Whether the increased cost of such in-house anesthesiology coverage at level II trauma centers is justified by its clinical benefit remains an unanswered question.

Associations between baseline cognitive status and motor outcomes after treadmill training in people with Parkinson's disease: a pilot study.

PURPOSE: To determine the effect of baseline cognition on gait outcomes after a treadmill training program for people with Parkinson's disease (PD). METHODS: This pilot clinical trial involved people with PD who were classified as having no cognitive impairment (PD-NCI) or mild cognitive impairment (PD-MCI). Baseline executive function and memory were assessed. The intervention was a 10-week gait training program (twice-weekly treadmill sessions), with structured speed and distance progression and verbal cues for gait quality. Response to intervention was assessed by gait speed measured after week 2 (short-term) and week 10 (long-term). RESULTS: Participants (n = 19; 12 PD-NCI, 7 PD-MCI) had a mean (standard deviation) age of 66.5 (6.3) years, disease duration of 8.8 (6.3) years, and MDS-UPDRS III score of 21.3 (10.7). Gait speed increased at short-term and long-term assessments. The response did not differ between PD-NCI and PD-MCI groups; however, better baseline memory performance and milder PD motor severity were independently associated with greater improvements in gait speed in unadjusted and adjusted models. CONCLUSIONS: These findings suggest that memory impairments and more severe motor involvement can influence the response to gait rehabilitation in PD and highlight the need for treatments optimized for people with greater cognitive and motor impairment.IMPLICATIONS FOR REHABILITATIONCognitive deficits in Parkinson's disease (PD) could impact motor learning and gait rehabilitation, yet little is known about the effects of cognitive impairments on the response to rehabilitation in people with PD.This study demonstrates that the response to gait rehabilitation did not differ between people with PD who had no cognitive impairment and those with mild cognitive impairment.Across all participants, better baseline memory was associated with greater improvements in gait speed.Rehabilitation professionals should be mindful of PD severity, as those with more substantial memory and motor impairments may require additional dosing or support to maximize gait training benefits.

Associations Between Physical Activity Vital Sign in Patients and Health Care Utilization in a Health Care System, 2018-2020.

BACKGROUND: Physical inactivity is a risk factor for many chronic conditions. This retrospective cohort study examined associations between physical activity (PA) with health care utilization (HU). METHODS: A PA vital sign was recorded in clinics from January 2018 to December 2020. Patients were categorized as inactive, insufficiently active, or sufficiently active by US PA aerobic guidelines. Associations between PA vital sign and visits (inpatient admissions, emergency department, urgent care, and primary care) were estimated using population average regression by visit type. RESULTS: 23,721 patients had at least one PA vital sign recorded, with a mean age of 47.3 years and mean body mass index (BMI) of 28; 52% were female and 63% were White. Sufficiently active patients were younger, male, White, and had lower BMI than insufficiently active patients. Achieving 150 minutes per week of moderate to vigorous PA per 1000 patient years was associated with 34 fewer emergency department visits (P < .001), 19 fewer inpatient admissions (P < .001), and 38 fewer primary care visits (P < .001) compared with inactive patients. Stronger associations between lower PA and higher HU were present among those who were older or had a higher comorbidity. BMI, sex, ethnicity, and race did not modify the association between PA and HU. CONCLUSIONS: Meeting aerobic guidelines was associated with reduced HU for inpatient, primary care, and emergency department visits.

Analyzing the value of IONM as a complex intervention: The gap between published evidence and clinical practice.

OBJECTIVE: Intraoperative neurophysiological monitoring (IONM) was investigated as a complex intervention (CI) as defined by the United Kingdom Medical Research Council (MRC) in published studies to identify challenges and solutions in estimating IONM's effects on postoperative outcomes. METHODS: A scoping review to April 2022 of the influence of setting on what was implemented as IONM and how it influenced postoperative outcomes was performed for studies that compared IONM to no IONM cohorts. IONM complexity was assessed with the iCAT_SR tool. Causal graphs were used to represent this complexity. RESULTS: IONM implementation depended on the surgical procedure, institution and/or surgeon. "How" IONM influenced neurologic outcomes was attributed to surgeon or institutional experience with the surgical procedure, surgeon or institutional experience with IONM, co-interventions in addition to IONM, models of IONM service delivery and individual characteristics of the IONM provider. Indirect effects of IONM mediated by extent of tumor resection, surgical approach, changes in operative procedure, shorter operative time, and duration of aneurysm clipping were also described. There were no quantitative estimates of the relative contribution of these indirect effects to total IONM effects on outcomes. CONCLUSIONS: IONM is a complex intervention whose evaluation is more challenging than that of a simple intervention. Its implementation and largely indirect effects depend on specific settings that are usefully represented in causal graphs. SIGNIFICANCE: IONM evaluation as a complex intervention aided by causal graphs and multivariable analysis could provide a valuable framework for future study design and assessments of IONM effectiveness in different settings.

Effects of prosthetic feet on metabolic energy expenditure in people with transtibial amputation: A systematic review and meta-analysis.

OBJECTIVE: To assess the effects of different prosthetic feet on energy costs associated with walking and running in people with transtibial amputation. LITERATURE SURVEY: The Pubmed, CINAHL, and Web-of-Science bibliographic databases were searched for original research published through June 30, 2018. References from identified articles were also reviewed. METHODOLOGY: Two reviewers screened titles, abstracts, and articles for pertinent studies. Details were extracted with a standardized template. Risk of bias was assessed using domain-based methods. Prosthetic feet were grouped into categories and compared according to energy costs associated with walking or running over various terrain conditions. Meta-analyses were conducted when data quantity and homogeneity permitted. Evidence statements were formed when results were consistent or undisputed. SYNTHESIS: Fifteen studies were included. Participants (n = 141) were predominantly male (87.9%), had unilateral amputation (95.7%) from non-dysvascular causes (87.9%), and were classified as unlimited community ambulators or active adults (56.0%). Participants were often young but varied in age (mean age 24.8-66.6 years). Available evidence indicates that feet with powered dorsiflexion reduce energy costs relative to dynamic response feet in unlimited community ambulators or active adults when walking on level or declined surfaces. Dynamic response feet do not significantly reduce energy costs compared to energy storing, flexible keel, or solid ankle feet when walking on level terrain. Running feet do not reduce energy costs relative to dynamic response in active adults when running. Select feet may reduce energy costs under specific conditions, but additional research is needed to confirm preliminary results. CONCLUSIONS: The overall body of evidence is based on small samples, comprised mostly of participants who may not well represent the population of prosthesis users and test conditions that may not well reflect how prostheses are used in daily life. However, evidence suggests energy costs are affected by prosthetic foot type only under select conditions.

Oral adverse outcomes associated with the buccal mucosa graft for urethroplasty.

OBJECTIVE: The buccal mucosa graft (BMG) is the standard graft for reconstructive urology, but management of the donor site remains under debate. The authors compared postoperative oral adverse outcomes between management methods (closure, nonclosure, or xenograft-assisted closure). STUDY DESIGN: A retrospective cohort study was conducted, enrolling patients treated at Harborview Medical Center, Seattle, Washington. The patients had a history of urethroplasty using a unilateral BMG, and the primary outcome variables were postoperative oral adverse outcomes, defined as subjective changes in mouth opening, smile, chewing, speech, intraoral bleeding, paresthesia, trismus, and infection. Multivariate and regression analyses were performed. RESULTS: The sample was composed of 137 patients (95% male; mean age, 48 years). The mean surface areas of the BMG for closure, nonclosure, and xenograft were 1059, 1178, and 1228 mm2, respectively. Thirty-four patients completed the survey (7 closure, 17 nonclosure, and 10 xenograft). Multiple linear regression showed a significant difference between the 3 groups with respect to patient-reported chewing ability and trismus favoring xenograft at larger graft sizes (P < .01). CONCLUSIONS: Xenograft-assisted closure may reduce long-term oral adverse outcomes associated with trismus and subjective changes in chewing, mouth opening, speaking, and smiling with larger grafts. In addition, limited postoperative patient education for oral rehabilitation exercises was noted.

COVID-19 vaccine hesitancy in adults with multiple sclerosis in the United States: A follow up survey during the initial vaccine rollout in 2021.

BACKGROUND: Multiple sclerosis (MS) organizations have recommended that adults with MS obtain the COVID-19 vaccination. Vaccine hesitancy is a barrier to full COVID-19 inoculation in the general population. Whether vaccine hesitancy is also a barrier towards optimizing vaccination rates in the MS community is unknown. To investigate vaccine hesitancy and inform efforts to increase vaccine uptake in the MS population, we conducted a follow up survey of a national sample of adults with MS living in the United States who completed an initial survey early in the COVID-19 pandemic. The current study aimed to answer questions vital to understanding vaccine hesitancy, specifically: (1) What is the prevalence of COVID-19 vaccine hesitancy in early 2021? (2) What are the reasons for and factors associated with current hesitancy? (3) How has vaccine willingness and hesitancy changed from April/May 2020 to January/February 2021? and (4) Who has changed in their vaccine willingness? METHODS: Adults with MS living in the United States (N = 359) completed two online surveys (the first between 10 April 2020 and 06 May 2020; the second between 11 January 2021 and 08 February 2021) about their willingness and intent to obtain a COVID-19 vaccine. Participants also completed measures to assess factors potentially related to vaccine hesitancy, including demographics, MS variables, influenza vaccine history, vaccine concerns, and contextual factors, including perceived risk for SARS-CoV-2 infection, trust in COVID-19 information source, anxiety, and loneliness. RESULTS: Of the participants who completed the second survey in early 2021, 20.3% were vaccine hesitant, that is, either reporting that they were undecided (13.9%) or not intending to get vaccinated (6.4%). Vaccine hesitancy decreased between the two surveys, with nearly three-fourths (73.8%) of the second sample reporting that they planned to obtain the COVID-19 vaccine. Vaccine hesitancy was associated with having a lower level of education, being non-White, not having a recent flu vaccination, holding a lower perception of one's risk of getting COVID-19, and having lower trust in the Centers for Disease Control and Prevention. Participants who were vaccine hesitant reported concerns about the long-term effects of the vaccine, the vaccine approval process, and the potential impact of the vaccine given their own health conditions/history. Notably, 90% of the undecided group wanted additional information about the vaccine before deciding. Vaccine willingness changed over time, with many of those who were somewhat willing more willing to get the COVID-19 vaccine at survey 2. Individuals who were unwilling at survey 1 were highly likely to remain unwilling at survey 2. CONCLUSION: Overall, COVID-19 vaccine hesitancy decreased during the pandemic, although one in five adults with MS were hesitant in early 2021. Of those who were undecided, most indicated that they wanted additional information about the vaccine before deciding whether to be vaccinated, suggesting additional educational efforts on the vaccine's safety, long-term effects, and potential health implications are still needed. Findings indicate that public health efforts may be best focused on those who are undecided, whose vaccine hesitancy may change over time and, possibly, with appropriate information or intervention.
