Eye movements desensitization and reprocessing with finger movements and Elite mobile health software on guilt feeling of parents of children with autism: A randomized trial.

WHAT IS KNOWN ON THE SUBJECT?: Taking care of an autistic child at home can be tough for parents. They struggle to balance caring for their child and other tasks. This can affect their emotional well-being and cause guilt and other psychological problems. WHAT DOES THE PAPER ADD TO EXISTING KNOWLEDGE?: Eye movement desensitization and reprocessing with finger movements can reduce guilt in parents of autistic children. Eye movement desensitization and reprocessing with Elite mobile health software movements can reduce guilt in parents of autistic children. The bilateral eye stimulation method using finger movements has a more sustained impact than the Elite app's bilateral stimulation method. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Healthcare providers are encouraged to learn Eye Movements Desensitization and Reprocessing. Healthcare providers are encouraged to use these methods to help with psychological issues in children with autism. Psychiatric nurses are encouraged to utilize this treatment approach for parents of children with autism, as well as to help alleviate feelings of guilt more broadly. ABSTRACT: INTRODUCTION: Caring for an autistic child at home can be challenging for parents, as it can make it difficult to balance their responsibilities. This imbalance can negatively affect the emotional well-being of the caregiver and lead to feelings of guilt. While this is a known issue, there may be gaps in knowledge specific to Iran. In this study, a new method was introduced to address this issue. AIM: This study aimed to examine the impact of desensitization with eye movements and reprocessing (EMDR) on reducing parental guilt among autistic children's families. We aim to examine the effectiveness of two different treatment methods. METHODS: This study involved 90 parents (60 mothers, 30 fathers) of autistic children randomly assigned to either an experimental or control group. The two experimental groups received a 45-min intervention session once a week for 3 weeks, while the control group did not receive any intervention. Data on feelings of guilt was collected using a questionnaire. After 30 days, both groups took a follow-up test. The data were analysed using statistical software. RESULTS: This study found that there were significant differences in guilt feelings among different groups of EMDR therapy and a control group. Specifically, no significant differences were observed in the mean guilt scores between the experimental and control groups at the pre-intervention stage (p > .05). However, the experimental groups exhibited significantly lower mean guilt scores immediately after the intervention and 1 month later than the control group (p < .05). Immediately after the intervention and 1 month later, no significant differences were observed between the two experimental groups (p > .05). CONCLUSIONS: The findings of this study demonstrate the efficacy of desensitization treatment using eye movements and reprocessing in reducing feelings of guilt among autistic children's parents. In the follow-up phase, it seems that the two-way stimulation method with finger movements is more effective than Elite software in terms of the continuity of the effect. Healthcare providers are encouraged to learn and use these methods to help prevent and treat psychological issues in autistic children.

Aberrant bowel movement frequencies coincide with increased microbe-derived blood metabolites associated with reduced organ function.

Bowel movement frequency (BMF) directly impacts the gut microbiota and is linked to diseases like chronic kidney disease or dementia. In particular, prior work has shown that constipation is associated with an ecosystem-wide switch from fiber fermentation and short-chain fatty acid production to more detrimental protein fermentation and toxin production. Here, we analyze multi-omic data from generally healthy adults to see how BMF affects their molecular phenotypes, in a pre-disease context. Results show differential abundances of gut microbial genera, blood metabolites, and variation in lifestyle factors across BMF categories. These differences relate to inflammation, heart health, liver function, and kidney function. Causal mediation analysis indicates that the association between lower BMF and reduced kidney function is partially mediated by the microbially derived toxin 3-indoxyl sulfate (3-IS). This result, in a generally healthy context, suggests that the accumulation of microbiota-derived toxins associated with abnormal BMF precede organ damage and may be drivers of chronic, aging-related diseases.

Does pre-speech auditory modulation reflect processes related to feedback monitoring or speech movement planning?

Previous studies have revealed that auditory processing is modulated during the planning phase immediately prior to speech onset. To date, the functional relevance of this pre-speech auditory modulation (PSAM) remains unknown. Here, we investigated whether PSAM reflects neuronal processes that are associated with preparing auditory cortex for optimized feedback monitoring as reflected in online speech corrections. Combining electroencephalographic PSAM data from a previous data set with new acoustic measures of the same participants' speech, we asked whether individual speakers' extent of PSAM is correlated with the implementation of within-vowel articulatory adjustments during /b/-vowel-/d/ word productions. Online articulatory adjustments were quantified as the extent of change in inter-trial formant variability from vowel onset to vowel midpoint (a phenomenon known as centering). This approach allowed us to also consider inter-trial variability in formant production and its possible relation to PSAM at vowel onset and midpoint separately. Results showed that inter-trial formant variability was significantly smaller at vowel midpoint than at vowel onset. PSAM was not significantly correlated with this amount of change in variability as an index of within-vowel adjustments. Surprisingly, PSAM was negatively correlated with inter-trial formant variability not only in the middle but also at the very onset of the vowels. Thus, speakers with more PSAM produced formants that were already less variable at vowel onset. Findings suggest that PSAM may reflect processes that influence speech acoustics as early as vowel onset and, thus, that are directly involved in motor command preparation (feedforward control) rather than output monitoring (feedback control).

Patterns, outcomes, and preventability of clinically manifest drug-drug interactions in older outpatients: a subgroup analysis from a 6-year-long observational study in North India.

Older adults are vulnerable to adverse drug reactions (ADRs) and drug-drug interactions (DDIs). Evidence on clinically manifest DDIs in older outpatients is scanty. The present study aims to report clinically manifest DDIs, their risk factors, and preventive measures. A subgroup analysis of a 6-year (2015-2021) long prospective study was conducted in a tertiary hospital in North India. Older outpatients with ADRs constituted the study participants. Among 933 ADRs reported in 10,400 patient registrations, clinically manifest DDIs were involved in 199 (21.3%). DDIs accounted for 29.9%, 26.5%, and 21.3% of drug-related metabolic, vascular, and nervous system disorders, respectively. Movement disorders (n = 18), hypotension (n = 16), and hypoglycemia (n = 15) were the most common manifestations. Eighty-six percent of DDIs were of the pharmacodynamic type, and 13.1% were immune-mediated. Around 35% of DDIs resulted in hospitalization, with hyponatremia, movement disorder, and renal impairment as the common reasons. Older adults with Parkinsonism, infection, coronary artery disease, neuropsychiatric disease, and diabetes mellitus, respectively, had 3.28, 2.85, 1.97, 1.76, and 1.80 times higher odds of DDIs. Those receiving ≥ 10 drugs had 5.31 times higher odds of DDIs compared to individuals receiving 1-4 drugs. "Avoiding the causative drug," "optimal monitoring of the patient," and "start-low and go-slow" policy together could prevent 85% of DDIs. In conclusion, every fifth case of ADRs and nearly one third of ADR-related hospitalizations in older adults are related to DDIs. Movement disorder, hypotension, and hypoglycemia are the common manifestations. A holistic approach with drug omission, optimal patient monitoring, and slow titration of therapy can prevent significant DDIs in older adults.

Frequency of and risk factors associated with local recurrence after spinal stereotactic body radiation therapy without surgery.

PURPOSE: This study aimed to identify factors associated with local recurrence after spinal stereotactic body radiation therapy (SBRT), focusing on patient movement during treatment and tumor characteristics. METHODS: A total of 48 patients who underwent spinal SBRT alone without surgery from August 2017 to October 2022 were evaluated. Logistic regression analysis was conducted to identify factors associated with local recurrence, including patient movement and tumor characteristics such as soft tissue involvement and tumor volume. Patient movement during treatment was measured using cone beam computed tomography before and after irradiation. RESULTS: Among the included cases, 68.7% and 42.6% had soft tissue involvement and movement exceeding 1 mm, respectively. The median follow-up duration for local recurrence was 11.6 (range: 0.7-44.9) months, whereas the median duration to local recurrence was 6.3 months. Within 12 months, 29.3% of the patients experienced local recurrence, among whom 43.9% moved ≥ 1 mm during treatment, whereas 15.8% did not move. Univariable analysis found that both soft tissue involvement (OR = 10.3, 1.21-87.9; p = 0.033) and patient movement ≥ 1 mm (OR = 5.75, 1.45-22.8; p = 0.013) were associated with local recurrence. Multivariable analysis identified patient movement as an independent prognostic factor for local recurrence (OR = 5.15, 1.06-25.0; p = 0.042). CONCLUSION: Our results suggest that patient movement during spinal SBRT was associated with local recurrence, emphasizing the need for better immobilization techniques and shorter delivery times to improve tumor control.

Tablet-based Rey-Osterrieth Complex Figure copy task: a novel application to assess spatial, procedural, and kinematic aspects of drawing in children.

The paper-and-pencil Rey-Osterrieth Complex Figure (ROCF) copy task has been extensively used to assess visuo-constructional skills in children and adults. The scoring systems utilized in clinical practice provide an integrated evaluation of the drawing process, without differentiating between its visuo-constructional, organizational, and motor components. Here, a tablet-based ROCF copy task capable of providing a quantitative assessment of the drawing process, differentiating between visuo-constructional, organizational, and motor skills, is trialed in 94 healthy children, between 7 and 11 years of age. Through previously validated algorithms, 12 indices of performance in the ROCF copy task were obtained for each child. Principal component analysis of the 12 indices identified spatial, procedural, and kinematic components as distinct dimensions of the drawing process. A composite score for each dimension was determined, and correlation analysis between composite scores and conventional paper-and-pencil measures of visuo-constructional, procedural, and motor skills performed. The results obtained confirmed that the constructional, organizational, and motor dimensions underlie complex figure drawing in children; and that each dimension can be measured by a unique composite score. In addition, the composite scores here obtained from children were compared with previsions results from adults, offering a novel insight into how the interplay between the three dimensions of drawing evolves with age.

Efferent pathways from the suprachiasmatic nucleus to the horizontal limbs of diagonal band promote NREM sleep during the dark phase in mice.

The regulation of circadian rhythms and the sleep-wake states involves in multiple neural circuits. The suprachiasmatic nucleus (SCN) is a circadian pacemaker that controls the rhythmic oscillation of mammalian behaviors. The basal forebrain (BF) is a critical brain region of sleep-wake regulation, which is the downstream of the SCN. Retrograde tracing of cholera toxin subunit B showed a direct projection from the SCN to the horizontal limbs of diagonal band (HDB), a subregion of the BF. However, the underlying function of the SCN-HDB pathway remains poorly understood. Herein, activation of this pathway significantly increased non-rapid eye movement (NREM) sleep during the dark phase by using optogenetic recordings. Moreover, activation of this pathway significantly induced NREM sleep during the dark phase for first 4 h by using chemogenetic methods. Taken together, these findings reveal that the SCN-HDB pathway participates in NREM sleep regulation and provides direct evidence of a novel SCN-related pathway involved in sleep-wake states regulation.

Dynamic gait stability in people with mild to moderate Parkinson's disease.

BACKGROUND: Falls are a serious health threat for people with Parkinson's disease. Dynamic gait stability has been associated with fall risk. Developing effective fall prevention interventions requires a sound understanding of how Parkinson's disease affects dynamic gait stability. This study compared dynamic gait stability within the Feasible Stability Region framework between people with and without Parkinson's disease during level walking at a self-selected speed. METHODS: Twenty adults with Parkinson's disease and twenty age- and gender-matched healthy individuals were recruited. Dynamic gait stability at two gait instants: touchdown and liftoff, was assessed as the primary outcome measurement. Spatiotemporal gait parameters, including stance phase duration, step length, gait speed, and cadence were determined as explanatory variables. FINDINGS: People with Parkinson's disease walked more slowly (p < 0.001) with a shorter step (p = 0.05), and prolonged stance phase (p = 0.04) than their healthy peers with moderate to large effect sizes. Dynamic gait stability did not show any group-associated differences (p > 0.36). INTERPRETATION: Despite the different gait parameters between groups, people with Parkinson's disease exhibited similar dynamic gait stability to their healthy counterparts. To compensate for the potential dynamic gait stability deficit resulting from slow gait speed, individuals with Parkinson's disease adopted a short step length to shift the center of mass motion state closer to the Feasible Stability Region. Our findings could provide insight into the impact of Parkinson's disease on the control of dynamic gait stability.

Evaluating the Long-term Stability of a Predefined Palatal Region for Tooth Movement Analysis.

OBJECTIVES: We conducted a three-dimensional (3D) analysis of orthodontic tooth movement (TM) using digital dental models (DMs), focusing on the palatal region of interest (PROI), aiming to evaluate the long-term stability of the PROI, validate the 3D TM analysis with PROI registration, and compare it with conventional lateral cephalometric analyses. METHODS: Twenty adult patients treated with a multibracket appliance were evaluated at their first visit (T0) and at least 5 years later (T1) using DMs and lateral cephalograms (LCs). The long-term stability of PROI was assessed by calculating the point cloud distances between DM-T0 and DM-T1. TM analysis using DM with PROI registration for the maxillary central incisors was assessed through linear and angular measurements in the sagittal view and subsequently compared with the LCs. RESULTS: The average point cloud distance of the PROI between DM-T0 and DM-T1 was 0.21 mm (standard deviation, 0.13 mm). TM analysis using DMs demonstrated excellent reproducibility for both linear and angular measurements (intra-rater correlation coefficient, > 0.99). The 95% limits of agreement between the DM and LC measurements were < 5.14° for angular change, 3.53 mm for vertical displacement, and 0.98 mm for horizontal displacement. No significant differences were observed in the angular and linear measurements when the TM was compared using the DMs and LCs. CONCLUSIONS: The PROI remained stable for over 5 years, supporting the reproducibility and accuracy of TM assessment using PROI registration in orthodontic clinical practice. CLINICAL SIGNIFICANCE: DM analysis lacks the risks associated with X-ray exposure and can be easily performed in daily clinical practice, indicating its potential for future clinical applications. These findings further support the use of DM with PROI registration for TM analysis in orthodontic clinical practice, emphasizing its long-term stability and reproducibility.

Expanding the genetics and phenotypes of ocular congenital cranial dysinnervation disorders.

PURPOSE: To identify genetic etiologies and genotype/phenotype associations for unsolved ocular congenital cranial dysinnervation disorders (oCCDDs). METHODS: We coupled phenotyping with exome or genome sequencing of 467 probands (550 affected and 1108 total individuals) with genetically unsolved oCCDDs, integrating analyses of pedigrees, human and animal model phenotypes, and de novo variants to identify rare candidate single nucleotide variants, insertion/deletions, and structural variants disrupting protein-coding regions. Prioritized variants were classified for pathogenicity and evaluated for genotype/phenotype correlations. RESULTS: Analyses elucidated phenotypic subgroups, identified pathogenic/likely pathogenic variant(s) in 43/467 probands (9.2%), and prioritized variants of uncertain significance in 70/467 additional probands (15.0%). These included known and novel variants in established oCCDD genes, genes associated with syndromes that sometimes include oCCDDs (e.g., MYH10, KIF21B, TGFBR2, TUBB6), genes that fit the syndromic component of the phenotype but had no prior oCCDD association (e.g., CDK13, TGFB2), genes with no reported association with oCCDDs or the syndromic phenotypes (e.g., TUBA4A, KIF5C, CTNNA1, KLB, FGF21), and genes associated with oCCDD phenocopies that had resulted in misdiagnoses. CONCLUSION: This study suggests that unsolved oCCDDs are clinically and genetically heterogeneous disorders often overlapping other Mendelian conditions and nominates many candidates for future replication and functional studies.

Applications of nanotechnology in orthodontics: a comprehensive review of tooth movement, antibacterial properties, friction reduction, and corrosion resistance.

Nanotechnology has contributed important innovations to medicine and dentistry, and has also offered various applications to the field of orthodontics. Intraoral appliances must function in a complex environment that includes digestive enzymes, a diverse microbiome, mechanical stress, and fluctuations of pH and temperature. Nanotechnology can improve the performance of orthodontic brackets and archwires by reducing friction, inhibiting bacterial growth and biofilm formation, optimizing tooth remineralization, improving corrosion resistance and biocompatibility of metal substrates, and accelerating or decelerating orthodontic tooth movement through the application of novel nanocoatings, nanoelectromechanical systems, and nanorobots. This comprehensive review systematically explores the orthodontic applications of nanotechnology, particularly its impacts on tooth movement, antibacterial activity, friction reduction, and corrosion resistance. A search across PubMed, the Web of Science Core Collection, and Google Scholar yielded 261 papers, of which 28 met our inclusion criteria. These selected studies highlight the significant benefits of nanotechnology in orthodontic devices. Recent clinical trials demonstrate that advancements brought by nanotechnology may facilitate the future delivery of more effective and comfortable orthodontic care.

Cholinergic input to mouse visual cortex signals a movement state and acutely enhances layer 5 responsiveness.

Acetylcholine is released in visual cortex by axonal projections from the basal forebrain. The signals conveyed by these projections and their computational significance are still unclear. Using two-photon calcium imaging in behaving mice, we show that basal forebrain cholinergic axons in the mouse visual cortex provide a binary locomotion state signal. In these axons, we found no evidence of responses to visual stimuli or visuomotor prediction errors. While optogenetic activation of cholinergic axons in visual cortex in isolation did not drive local neuronal activity, when paired with visuomotor stimuli, it resulted in layer-specific increases of neuronal activity. Responses in layer 5 neurons to both top-down and bottom-up inputs were increased in amplitude and decreased in latency, whereas those in layer 2/3 neurons remained unchanged. Using opto- and chemogenetic manipulations of cholinergic activity, we found acetylcholine to underlie the locomotion-associated decorrelation of activity between neurons in both layer 2/3 and layer 5. Our results suggest that acetylcholine augments the responsiveness of layer 5 neurons to inputs from outside of the local network, possibly enabling faster switching between internal representations during locomotion.

Microscopic and submicroscopic exploration of diplolepideae peristome structures in hygroscopic movement.

BACKGROUND: The Diplolepideae are the larger group within the Arthrodontae mosses, characterized by peristomes formed from residual cell walls. It is now understood that these peristomes exhibit diverse hygroscopic movements, playing a crucial role in spore release. However, the exact mechanism behind this movement remains unclear, lacking direct evidence. This study investigated the microscopic and submicroscopic structures of the peristomes in three Diplolepideae species: Hypopterygium fauriei (Besch.), Pylaisia levieri (Müll. Hal.) Arikawa and Regmatodon declinatus (Hook.) Brid. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to reveal the differences in their hygroscopic movement mechanisms. RESULTS: The three species exhibited distinct responses upon wetting: H. fauriei's exostome closed inwards, P. levieri' opened outwards, and R. declinatus' elongated significantly. These differences are attributed to the varying microfibril deposition in the exostome layers. Uniform deposition in the inner layer and minimal deposition in the outer layer enabled exostome opening upon wetting and closing when dry. Our findings suggest that the diastole and contraction of fine microfibrils in the exostome plates and ridges are the key drivers of hygroscopic movement. CONCLUSIONS: This study provides further evidence at both the structural and submicroscopic levels, contributing to the unraveling of the hygroscopic movement mechanism in Diplolepideae peristomes. This enhanced understanding sheds light on the relationship between peristome structure and function.

The Persistent Paradox of Rapid Eye Movement Sleep (REMS): Brain Waves and Dreaming.

The original conceptualization of REM sleep as paradoxical sleep was based on its EEG resembling wakefulness and its association with dreaming. Over time, the concept of paradox was expanded to include various associations with REM sleep, such as dream exclusivity, high recall, and pathophysiology. However, none of these associations are unique to REM sleep; they can also occur in other sleep states. Today, after more than fifty years of focused research, two aspects of REMS clearly retain paradoxical exclusivity. Despite the persistent contention that the EEG of human REMS consists of wake-like, low-voltage, non-synchronous electrical discharges, REMS is based on and defined by the intracranial electrical presence of 5-8 Hz. theta, which has always been the marker of REMS in other animals. The wake-like EEG used to define REMS on human polysomnography is secondary to a generalized absence of electrophysiological waveforms because the strong waves of intracranial theta do not propagate to scalp electrodes placed outside the skull. It is a persistent paradox that the theta frequency is restricted to a cyclical intracranial dynamic that does not extend beyond the lining of the brain. REMS has a persistent association with narratively long and salient dream reports. However, the extension of this finding to equate REMS with dreaming led to a foundational error in neuroscientific logic. Major theories and clinical approaches were built upon this belief despite clear evidence that dreaming is reported throughout sleep in definingly different physiologic and phenomenological forms. Few studies have addressed the differences between the dreams reported from the different stages of sleep so that today, the most paradoxical aspect of REMS dreaming may be how little the state has actually been studied. An assessment of the differences in dreaming between sleep stages could provide valuable insights into how dreaming relates to the underlying brain activity and physiological processes occurring during each stage. The brain waves and dreams of REMS persist as being paradoxically unique and different from waking and the other states of sleep consciousness.

Increased Semantic Memorization in Children with ADHD during a Paradigm of Motor Priming: Exploratory Findings.

AIM: The aim was to evaluate the effect of body actions on learning process, particularly semantic memory capabilities in drug-naïve children with attention deficit hyperactivity disorder (ADHD). METHOD: Thirty children had to listen to a story which was repeated three times in a row and then a fourth time five minutes later. After each listen, the child was asked what she/he remembered from the story. The whole sample was split randomly into three subgroups of equal IQ (mean 102.2 ± 12.7), age (mean age 8 ± 0.6 years), sex (ratio female to male 1:5) and severity of ADHD symptoms (34.2 ± 7.4); a G1 "Freeze" subgroup, which implied listening to the story while sitting on a chair without moving; a G2 "Minimal" subgroup, which implied listening to the story while sitting on a chair but free movement was allowed; a G3 "Prescribed movement" subgroup, which implied listening to the story standing up, while copying the experimenter movements that mimicked the actions told in the story. RESULTS: Although our sample was limited in size, interestingly, children in the G3 subgroup showed the highest short-term semantic memory retention compared to G1. In all subgroups, repetition allowed an increase in performance. CONCLUSIONS: Our exploratory findings stress the positive role of movement in children with ADHD to increase semantic memorization. Hyperactivity may counteract the deficit of memorization related to attention impairment in children with ADHD. Our results may encourage parents or teachers to allow children with ADHD to move around during short-term memory-retention tasks.

Construct Validity of the Athlete Introductory Movement Screen in Grassroots Footballers Aged 11-13 Years.

BACKGROUND: This study examined the construct validity of the Athlete Introductory Movement Screen (AIMS) in children. METHODS: Following ethics approval, parental consent, and child assent, 87 children (50 boys, 37 girls) aged 11-13 years (Mean ± SD = 12.4 ± 0.6 years) performed the AIMS and Test of Gross Motor Development (TGMD-3) in a counterbalanced order. AIMS tertiles were subsequently created, classifying children with 'high', 'medium', or 'low' movement skills. RESULTS: A 2 (Gender) X 3 (AIMS tertile) ways analysis of covariance (ANCOVA), controlling for age and age at peak height velocity, with TGMD-3 scores as the dependant variable, indicated that TGMD-3 scores were significantly higher for girls categorised as having a medium movement skill compared to girls categorised as low, and those categorised having high movement skill compared to medium and low movement skill groups (all, p = 0.001). There was no difference in TGMD-3 scores for boys classed as having low and medium movement skills. Boys categorised as high for movement skills had significantly greater TGMD-3 scores than their peers categorised as having both low and medium movement skills (p = 0.001). CONCLUSIONS: As the AIMS differentiates the theoretically related construct of motor competence, this study demonstrates that the AIMS has construct validity as a measure of movement skill in children aged 11-13 years.

The Correlation between Motor Skill Proficiency and Academic Performance in High School Students.

The intricate relationship between physical health and cognitive development has been a focal point of multidisciplinary research, suggesting that motor skill proficiency could influence academic outcomes. This study aimed to investigate the correlation between motor control, mobility, stability-measured by the Functional Movement Screen (FMS)-and academic performance among high school students. Conducted with 201 participants from a public high school in Spain, this descriptive non-experimental research divided students into high and low academic performance groups based on their average grade scores, with the median used as the criterion for distinction. The FMS was utilized to assess fundamental motor skills, and academic performance was verified across mathematics, language, science, and physical education subjects. The findings revealed a significant positive relationship between the FMS scores and academic achievement (r = 0.691; p < 0.001), indicating that students with higher motor skill proficiency had higher academic achievement. This correlation persisted across the various subjects, highlighting the potential benefits of integrating physical education and motor skill development into educational strategies. The study's results suggest that educational policies should advocate for comprehensive physical education programs to foster both physical well-being and academic improvement, thereby promoting a holistic educational model that enhances student performance across disciplines.
