Association between electroencephalogram alpha-band oscillations and executive and processing functions in patients with cerebral small vessel diseases.

Electroencephalogram (EEG) alpha-band oscillations may reflect executive and processing function in patients with cerebral small vessel disease (CSVD). We aimed to assess such association and its relationship with CSVD severity, and to identify specific alpha-band parameters and the cut-off values for cognitive screening. We analysed the dispersion of amplitude-frequency characteristics of EEG alpha-band and different alpha-band parameters (PFα , ΔPFα , PPα , NCL) in different brain locations. We also assessed patients' executive and processing functions using verbal fluency test (VFT) and color trails test (CTT), and CSVD severity using total burden and Fazekas scores. 129 patients were recruited in the study. After adjusting for age, gender and education, PFα(F3), PFα(F4) and NCL were significantly associated with VFT-composite performance (p < 0.05). CTT-1 time and error were associated with PFα(F3), PFα(F4), ΔPFα(O1;F3) and CSVD severity (p < 0.05), whereas CTT-2 time was only associated with CSVD severity. Moreover, the correlations between alpha-band oscillations and cognitive function were higher in low than in high disease-severity group (ρ: -0.58 vs. -0.38, p < 0.05). The AUC of selected alpha-band parameters were higher than 0.8 for VFT and CTT. Specific alpha-band parameters in the frontal lobe were identified to correspond to executive and processing function. Assessing EEG alpha-band oscillations may assist in screening cognitive impairment.

Humanistic burden of pediatric type 1 diabetes on children and informal caregivers: systematic literature reviews.

BACKGROUND: Diagnosis of children with type 1 diabetes (T1D) imposes an unprecedented burden on children and their caregivers. OBJECTIVE: To assess the burden of T1D on children and their informal caregivers, both after a recent diagnosis or after a longer duration of disease. METHODS: A series of systematic literature reviews were performed to explore the burden of T1D on children with the disease and their primary informal caregivers, based on the time of diagnosis. After the extraction of the qualitative and quantitative data from the included studies, two literature-based conceptual frameworks were developed: on the burden of pediatric T1D on children, and on informal caregivers. A third conceptual framework on the shared burden of pediatric T1D on both children and informal caregivers as part of the same family unit was also developed. RESULTS: The review of literature has identified a series of factors that affect the quality of life of children with T1D and their informal caregivers, with a direct impact on physical, emotional, and social outcomes. Generally, female patients and older adolescents experience more worry and stress that affects their quality of life. Other categories of factors affecting the child's and caregiver's burden include social, emotional, and physical factors, treatment-related and disease-related factors, as well as their coping abilities. Anxiety, depression, stress, and worry were commonly found among children and caregivers, starting with the diagnosis of T1D and continuing over time in relation to new challenges pertaining to aging or the disease duration. CONCLUSION: T1D causes a significant burden to affected children and their caregivers, both independently and through transactional interaction within the family unit. Disease burden can be reduced by strengthening individuals for the benefit of the whole family.

Complex interactive multimodal intervention to improve personalized stress management among healthcare workers in China: A knowledge translation protocol.

Objectives: Numerous stress management interventions have been implemented in the workplace, but few are adapted to the healthcare setting. Due to the nature of their jobs, healthcare workers (HCWs) may find it difficult to adopt recommended stress management strategies. We present the protocol for a 12-week personalized stress management intervention among HCWs to change their behavior as well as improve physiological/psychological outcomes. Methods: It is a pragmatic quasi-experimental study involving stressed HCWs from two general hospitals in Wuhan, China. The intervention group will receive a complex interactive multimodal intervention, including advanced education via mobile connection, participation in a web-based social network, tailored feedback, and the support of a nurse coach, while the control group will engage in self-guided stress management. Results: The primary outcome is centered on behavioral measures, namely improvements in stress management practice frequency after a 12-week intervention. The secondary outcomes are the changes in stress-related physiological indices (i.e. high frequency variability and normalized unit assessed by Holter) and psychological indicators (scores on the Perceived Stress Scale and Depression, Anxiety, Stress Scale) following 12 weeks of treatment. Conclusion: The knowledge translation intervention builds on a body of work defining the role of individualized instruction and feedback intervention, as well as group intervention through WeChat social network and personalized coaching. We believe this novel intervention will help HCWs promote their stress management awareness and skills, and ultimately benefit their long-term health.

Associations between Autonomic Function and Cognitive Performance among Patients with Cerebral Small Vessel Disease.

Data linking heart rate variability (HRV) and cognitive status remains controversial and scarce, particularly in cerebral small vessel disease (CSVD) patients. Whether the association between HRV and cognitive performance exists in CSVD patients is unclear. Hence, we aimed to investigate the association between HRV and cognitive performance in patients with CSVD. This cross-sectional study was conducted among 117 CSVD patients. All patients underwent HRV assessment and global cognitive evaluation by the Mini-Mental-State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). Multivariable analyses were performed to evaluate the association between HRV and cognitive status. The mean age of study population was 59.5 ± 11.8 years and 39.3% were female. After adjusting for confounding factors, a higher high frequency (HF) norm was independently associated with better MMSE scores (ß = 0.051; 95% confidence interval (CI): 0.012~0.090; p = 0.011) and MoCA scores (ß = 0.061; 95% CI: 0.017~0.105; p = 0.007), while a higher low frequency (LF)/HF ratio was independently associated with worse MMSE scores (ß = -0.492; 95% CI: -0.893~-0.092; p = 0.017) and MoCA scores (ß = -0.691; 95% CI: -1.134~-0.248; p = 0.003). The HF norm was positively associated with global cognitive performance, whereas the LF/HF ratio was negatively associated with global cognitive performance among CSVD patients. Further study of the relationship between autonomic function and cognitive performance is warranted.

Understanding the Implications of Peer Support for Families of Children With Neurodevelopmental and Intellectual Disabilities: A Scoping Review.

Background: Families are integrally involved in day-to-day caregiving of children with neurodevelopmental and intellectual disabilities (NDID). Given the widespread and increasing prevalence of children with NDID and the impact of family caregiving on psychological, social, and economic implications for both the child and family, understanding and supporting these families is an important public health concern. Objective: We conducted a scoping review on peer support networks to understand their implications on families. Considering increasing prevalence of NDID's, understanding the implications of existing networks is critical to improve and nurture future support networks that can complement and reduce the burden on existing formal support systems. Design: A comprehensive search of multiple databases was conducted. Articles were screened by two reviewers and any disagreements were resolved by a third reviewer. We explored existing research on parent-to-parent peer support networks, which included networks that developed informally as well as those that involved a formal facilitator for the group interpersonal processes. There were no limits on the study design, date and setting of the articles. We included all research studies in English that included an identifier for (i) "peer support networks," (ii) "children with neurodevelopmental and intellectual disabilities" and (iii) "family caregiver outcomes." Results: We identified 36 articles. Majority of the studies were conducted in North America, and were face to face networks. They included families of children with a wide range of NDIDs. Relevant information extracted from different studies highlighted peer support network characteristics and development process, needs of family caregivers attending these networks, factors affecting caregiver participation and the impact of peer support networks on family caregivers. These networks represent a way to strengthen family caregivers, developing resilience and social interactions. Family caregivers sharing similar experiences support one another and provide critical information to each other. Although results are encouraging, future studies incorporating improved study designs are needed to better evaluate the effectiveness of peer support networks. Furthermore, studies where peer support networks develop organically while the child is supported are warranted. Conclusion: Although results obtained are encouraging, our findings support the need for further research studies of peer support networks with better designs and more detailed description of the factors involved in the development.

Characteristics of mobile phone access and usage among caregivers in Pakistan - A mHealth survey of urban and rural population.

INTRODUCTION: Globally mobile ownership and access is becoming very common, and breakthroughs in mobile technology have shaped digital communication, with 7 billion mobile phone users globally. Developing countries account for 80% of newly purchased mobile phone devices with majority of such countries having low Routine Immunization coverage and a high risk of vaccine preventable diseases. The use of mobile phones provides a tremendous potential for public health involvement. OBJECTIVE: The aim of this study is to assess the acceptability and usability of mobile phones among infant caregivers in a LMIC setup and to explore the role of mHealth to improve immunization uptake and coverage. METHODS: This is a cross-sectional survey exploring the regional differences in mobile phone ownership, usability and preferences, along with level of trust with others while sharing a mobile phone. The study was conducted with caregivers of infants in an urban and rural sites of Pakistan. RESULTS: A total of 4472 households were approached, of which 3337 participants were eligible for the study (74.61 %). The reasons for not participating in the study (n = 1135) included (i) household locked or refusal to participate for 594 families (52%), (ii) child older than 14 days of life in 409 cases (36%), (iii) 80 (7%) families did not have access to a functional mobile phone, (iv) 36 (3%)families did not provide a mobile phone number, and (v) 14 (1%) could not stay within the HDSS for 6 months. Access to mobile phone with SMS features was considerably high at both sites: 99.1% in Matiari (rural site) and 96.7% in Karachi (urban). In Matiari 96.6% of the respondents reported having daily access to the phone, contrasting with only 51.4% in Karachi. In Karachi, the predominant spoken language was Urdu, whereas majority of the respondents in Matiari spoke Sindhi (34.6% vs. 70.9%). CONCLUSION: Our study indicates high access to mobile phone in both urban and rural setup, However access to smart phone is still limited, urban and rural setup. Further, the acceptance of overall health- and barrier-based child immunization messages through mobile phone were quite high in both settings. Lastly automated calls were preferred over SMS due to literacy and local settings. This bears important implications for improving child immunization uptake through mobile phones in developing regions such as Pakistan.

Impacts of Participation in Community-Based Physical Activity Programs on Cognitive Functions of Children and Youth with Neurodevelopmental Disabilities: A Scoping Review.

This review paper aimed to undertake an extensive exploration of the extent, range, and nature of research activities regarding the effect and emerging evidence in the field of physical activity interventions on cognitive development among children and youth (0-17.99 years) with neurodevelopmental disorders (NDD), and to help identify key gaps in research and determine precise research questions for future investigations. To carry out this scoping review, five electronic databases were searched. A total of 12,097 articles were retrieved via search efforts with an additional 93 articles identified from the identified review papers. Sixty articles were eligible for inclusion. The results of this scoping review revealed many positive key cognitive outcomes related to physical activity including, but not limited to: focus, attention, self-control, cognitive process, and alertness. No studies reported a negative association between physical activity and cognitive outcomes. Based on the findings from this scoping review, physical activity appears to have a favorable impact on the cognitive outcomes of children and youth with NDD.

Effects of Social Isolation and Loneliness in Children with Neurodevelopmental Disabilities: A Scoping Review.

Loneliness and social isolation have negative consequences on physical and mental health in both adult and pediatric populations. Children with neurodevelopmental disabilities (NDD) are often excluded and experience more loneliness than their typically developing peers. This scoping review aims to identify the type of studies conducted in children with NDD to determine the effects of loneliness and/or social isolation. Three electronic databases (Ovid MEDLINE, EMBASE, PsychINFO) were searched from inception until 5 February 2019. Two independent reviewers screened the citations for inclusion and extracted data from the included articles. Quantitative (i.e., frequency analysis) and qualitative analyses (i.e., content analysis) were completed. From our search, 5768 citations were screened, 29 were read in full, and 12 were included. Ten were case-control comparisons with cross-sectional assessment of various outcomes, which limited inference. Autism spectrum disorder, attention-deficit/hyperactivity disorder, and learning disorder were the most commonly studied NDD. This review showed that loneliness among children with NDD was associated with negative consequences on mental health, behaviour, and psychosocial/emotional development, with a likely long-term impact in adulthood. Lack of research in this area suggests that loneliness is not yet considered a problem in children with NDD. More studies are warranted using prospective designs and a larger sample size with a focus on the dynamic aspect of loneliness development.

The Effect of Massage on the Cardiac Autonomic Nervous System and Markers of Inflammation in Night Shift Workers: a Pilot Randomized Crossover Trial.

BACKGROUND: Shift work is a necessary part of many industries; however, it can have detrimental effects on health over time. PURPOSE: This study investigated the effect of a massage intervention on the cardiac autonomic activity and blood inflammatory markers of healthy medical residents working night shifts. SETTING: This trial was conducted at British Columbia Children's and Women's Hospital between February 2014 and June 2016. PARTICIPANTS: Included participants were generally healthy medical residents and were working rotating night shifts on a regular basis. RESEARCH DESIGN: This was a randomized, controlled, crossover, open-label trial (NCT02247089). INTERVENTIONS: Participants received either a 30-min massage intervention or reading control after consecutive periods of night shift. MAIN OUTCOME MEASURES: The primary outcome was high frequency, a proxy for the cardiac parasympathetic activity, measured via heart rate variability. Secondary outcomes included other heart rate variability measures, blood markers of inflammation, and blood pressure. RESULTS: Twelve participants were recruited (nine female) with median age of 28 years. There was no significant difference between the massage intervention and the reading control for the primary outcome, (median relative change between pre- and postmassage [interquartile range]: 62% [-1 to 150], pre- and postreading: 14% [-10 to 51], p = .16). Similarly, there was no difference with respect to blood inflammatory markers and blood pressure. Median high frequency significantly increased between pre- and postmassage (185 vs. 358 ms2, p = .04). CONCLUSION: This pilot study found no statistically significant difference between the massage intervention and the reading control; however, we did observe a significant increase in median high frequency from before massage to after massage, indicative of increased parasympathetic activity. This study may help inform planning of larger trials evaluating massage interventions on the activity of the autonomic nervous system and managing shift work stress.

Relationship between ischemic stroke locations, etiology subtypes, neurological outcomes, and autonomic cardiac function.

BACKGROUND: Post-stroke autonomic nervous dysfunction measured with heart rate variability (HRV) is correlated with the traditional risk factors and poor outcome. This study aimed to investigate the association between HRV and infarct locations, etiology subtypes, and neurological functional outcomes in patients with acute ischemic stroke (AIS). METHODS: In this prospective observational study, 186 consecutive patients were assigned to four major stroke severity categories based on the National Institutes of Health Stroke Scale score (NIHSS) and the modified Rankin Scale score (mRS): mild (NIHSS 0-4) stroke, moderate (NIHSS 5-14) stroke, 'favorable' (mRS 0-2) group, and 'unfavorable' (mRS 3-5) group. HRV time domain parameters were applied to evaluate the autonomic function of patients within 1 week after admission. All patients were classified into different etiology subtypes based on the TOAST (modified Trial of ORG 10172 in Acute Stroke Treatment) classification. The association of HRV with stroke location, etiology subtypes, neurological outcome was explored for all participants. Univariate and multivariate analyses were applied to explore the prediction value of HRV. RESULTS: 160 participants had large artery atherosclerotic infarction (LAA), 61 had right internal carotid artery system infarction (R-ICA), and 61 had vertebrobasilar artery system infarction (VB). Root-mean-square of differences (RMSSD) of adjacent RR intervals and the proportion calculated by dividing the interbeat interval differences >50 ms (pNN50) in patients of VB group was significantly lower than those of patients in R-ICA group (P < 0.01).  HRV parameters in the LAA group was significantly lower than non-LAA group (P < 0.01). At discharge, significant lower HRV presented in the unfavorable group and moderate group (P < 0.05). After logistic univariate and multivariate analysis, lower SDNN (OR = 1.019; 95% CI = 1.003-1.035; p= 0.021) was independently associated with unfavorable mRS and higher NIHSS at discharge (OR = 1.013; 95%CI = 1.003-1.024; p= 0.015). Only SDNN showed predictive value for mRS≥3 (OR = 1.012; 95%CI = 1.002-1.022; p= 0.016) at 1 year. CONCLUSIONS: HRV measured after admission is related to the AIS infarction basin, TOAST subtypes, and neurological outcomes at discharge suggesting a possible role for HRV in evaluating AIS and identifying high-risk patients.

The effects of antimuscarinic agents on the activity of the cardiac autonomic nervous system in children with functional overactive bladder.

BACKGROUND: Functional overactive bladder disorder is one of the most prevalent presentations of bladder and bowel dysfunction in children, and it is associated with lower overall cardiac autonomic and parasympathetic activity. Antimuscarinics are the most frequently used pharmacological agents for treatment of children with functional overactive bladder disorder; however, there is a gap in the literature in describing the effect of antimuscarinics on the autonomic profile of this population. OBJECTIVE: The aim of the study was to assess the cardiac parasympathetic activity before and after 12 weeks of oxybutynin treatment in children with overactive bladder. METHODS: This was a single-institution prospective cohort study. Cardiac autonomic activity was assessed during storage and voiding phases of the bladder function via spectral analysis of heart rate variability and impedance cardiography. The primary outcome measure was high frequency, a proxy for parasympathetic nervous system activity. Parameters of uroflow study, severity of symptoms, and quality of life outcomes were also assessed. RESULTS: Ten children (7 females) diagnosed with overactive bladder with a median age of 10 years (range = 6-14) were followed up for a median treatment duration of 11.8 weeks (range = 6-19.4). After treatment, there was a significant reduction in high frequency during the storage phase (median change = -24.17%, p = 0.047). No change was observed in the other outcome measures except for the overall Symptom Score for Dysfunctional Elimination Syndrome after treatment (5-point decrease, p = 0.034) (Summary Table). DISCUSSION: The findings of the present follow-up study suggest that the use of oxybutynin in children with overactive bladder is associated with a significant reduction in the activity of the parasympathetic nervous system. The clinical implications of this finding are important because similar autonomic profiles (as markers of chronic stress) have been shown to be associated with increased inflammation and are found in major chronic diseases. The authors caution making a clinical connection between the heart rate variability profile of the patients in this study and patients with chronic diseases because oxybutynin is usually not administered as long-term treatment for overactive bladder. CONCLUSION: Use of oxybutynin was associated with reduction in cardiac parasympathetic activity of children with functional overactive bladder. Further investigation into the role of the autonomic nervous system as a treatment target in the management of these children is warranted.

BRIGHT Coaching: A Randomized Controlled Trial on the Effectiveness of a Developmental Coach System to Empower Families of Children With Emerging Developmental Delay.

Background: In preschool-aged children with, or at elevated risk for, developmental disabilities, challenges and needs arise from vulnerabilities linked to critical and newly emerging cognitive, speech, motor, behavioral, and social skills. For families, this can be a stressful period as they witness the gradual unfolding of their child's differences and await to receive care. Nationally and internationally, service delivery models during this critical period are not standardized nor are they nimble or sufficient enough, leading to long wait times, service gaps and duplications. Given these struggles, there is a need to examine whether "health coaching", a structured educational program that is deliverable by different and more accessible means, can be effective in empowering families, by delivering information, providing social supports, and decreasing the demands on the overwhelmed health and developmental services. The primary objective is to evaluate the feasibility and the effectiveness of a coaching intervention (in comparison to usual and locally available care), for parents of children with emerging developmental delays. Method/Design: A multi-centered pragmatic randomized controlled trial design will be used. Families will be recruited from a representative sample of those awaiting publicly-funded regional child health services for children with developmental delays in four Canadian provinces. The target sample size is 392 families with children aged 1.5 to 4.5 years at recruitment date. Families will be randomly assigned to receive either the BRIGHT Coaching intervention (coach supported, hardcopy and online self-managed educational resources: 14 sessions, 2 sessions every 4 weeks for 6-9 months) or usual care that is locally available. In addition to the feasibility and acceptability measures, outcomes related to family empowerment, parental satisfaction and efficacy with caregiver competency will be evaluated at baseline, post-treatment (8 months), and follow-up (12 months). Discussion: This manuscript presents the background information, design, description of the interventions and of the protocol for the randomized controlled trial on the effectiveness of BRIGHT Coaching intervention for families of children with emerging developmental delays.

Personalized Text Messages and Automated Calls for Improving Vaccine Coverage Among Children in Pakistan: Protocol for a Community-Based Cluster Randomized Clinical Trial.

BACKGROUND: A major reason for poor childhood vaccine coverage in developing countries is the lack of awareness among parents and caregivers regarding the need for immunization and the importance of completing the entire series of vaccines. Short message service (SMS)-based interventions have been quite effective in different programs such as smoking cessation, treatment adherence, health care scheduled appointment attendance, antenatal care attendance, and compliance to immunization. However, there are limited data from low- and middle-income countries on the role of SMS and automated call-based messages and interventions to improve routine immunization (RI) coverage. OBJECTIVE: The primary objective of this study is to evaluate whether automated mobile phone-based personalized messages (SMS or automated call) can improve RI uptake at 6, 10, and 14 weeks of age per the expanded program immunization schedule, compared with a usual care control group. Secondary objectives include assessing the effects of different types of automated SMS text or calls on RI coverage at 20 weeks of age. METHODS: This is a mixed methods study using a clustered randomized controlled trial with 4 intervention arms and 1 control arm, augmented by qualitative interviews for personalizing the message. The study is being conducted in Pakistan (an urban site in Karachi and a rural site Matiari). In Karachi, 250 administrative structures are taken as 1 cluster, whereas in Matiari, a catchment area of 4 Lady Health Workers is considered as 1 cluster. The intervention targets families to receive weekly 1-way or 2-way (interactive) personalized automated SMS or automated phone call messages regarding vaccination. Possible barriers to vaccination are assessed in each family at the time of inclusion to determine the type of personalized messages that should be sent to the family to increase the chance of a positive response. Finally, in-depth interviews using purposive sampling are conducted before and after the trial to determine the family's vaccination experience and related factors. RESULTS: All study participants for the cluster randomized trial were enrolled by January 14, 2019. Study exit interviews at 20-weeks follow-up visits will be completed by June 2019. CONCLUSIONS: The results of this study will be useful to understand the respective effects of SMS text messages versus automated phone-based communication to improve RI coverage and timelines. Moreover, information regarding families' perceptions of vaccination and the daily life challenges for timely visits to the vaccine clinic will be used for developing more complex interventions that use mobile phone messages and possibly other approaches to overcome barriers in the uptake of correct and timely immunization practices.

Autonomic Parameter and Stress Profile Predict Secondary Ischemic Events After Transient Ischemic Attack or Minor Stroke.

Background and Purpose- Traditional risk factors for ischemic stroke are body stressors that are related to autonomic autonomic system (ANS) dysfunction. The value of ABCD2 score (age, blood pressure, clinical features, duration of symptoms, diabetes) to predict ischemic stroke after transient ischemic attack is compromised by the inclusion of a limited number of stressors. We aimed to assess whether markers of ANS function and stress could predict the occurrence of secondary ischemic events after transient ischemic attack or minor stroke. Methods- This is a prospective cohort study in which 201 patients were recruited within 48 hours after initial transient ischemic attack or minor stroke and followed for 90 days to assess the development of secondary ischemic events. ABCD2 score, heart rate variability (HRV) parameters as markers of ANS function, and psychological stress were assessed. Logistic regression and area under the curve (AUC) were used to assess the models' predictive ability. Results- Morning high frequency (HF) HRV power and changes in HF HRV from morning to afternoon (daytime HF changes) were the most useful HRV predictors for both ischemic events (AUC=0.61 and 0.70) and ischemic stroke (AUC=0.62 and 0.72). Compared with ABCD2 score, 2 HRV-based stress models showed higher predictive ability for ischemic events (AUC=0.82 versus 0.63, 0.76 versus 0.63; P<0.05) and ischemic stroke (AUC=0.87 versus 0.64, 0.82 versus 0.64; P<0.05). Conclusions- Assessing the effects of stress on the ANS may be an innovative way to stratify the risk of ischemic events after transient ischemic attack or minor stroke. New risk stratification by assessing the dynamic features of ANS dysfunction and stress may help identify high-risk sub-populations that may benefit from added management.

Gymnastic-Based Movement Therapy for Children With Neurodevelopmental Disabilities: Results From a Pilot Feasibility Study.

Background: Developmental and behavioral issues often limit the participation of children with neurodevelopmental disabilities (NDD) in community-based activities with their peers, which decreases opportunities for their social learning and development. Parents of children with NDD seek out programs that address physical and psychosocial development. Several studies already support the positive effects for the child to attend physical activity programs (PAPs). However, these studies are highly prone to biases and Hawthorne effect. In the planning stage of a large prospective study to assess the effectiveness of PAPs we reviewed the records of children who participated in a gymnastic-based program, the Empowering Steps Movement Therapy (ESMT). Besides generating useful data for developing the prospective study we thought these data reflect the rate of changes in context of normal practice in a naturalistic environment; therefore protected from Hawthorne effect and other biases. Design: This is a historical cohort: the files of 67 children with NDD were examined across a 2-year period (Jan 2011 to Jan 2013). As part of standard practice, the ESMT therapists document changes in motor function every 6 months, using the ESMT's proprietary motor scale. Parents also completed a parental questionnaire in June 2011 regarding their perceptions of changes in their child's physical and psychosocial function, as well as family functioning since their child started the program. Results: Linear Mixed Effects Model clearly identified three groups according to changes in motor function: the ones with rapid changes (mostly functional children with autism spectrum disorder: n = 13), the ones with moderate changes (different types of NDD diagnoses: n = 41) and the ones that did not change or even decreased motor skills over the follow-up (children with complex diseases or uncontrolled epilepsy despite treatment: n = 13). Parental questionnaires (n = 39) reported improvement in most of the children's physical and psychosocial abilities; they also indicated improvement in some of the family parameters. There was no association between the changes in children's motor functions and parents' responses to the questionnaire. Conclusion: Despite limitations due to the retrospective nature of the study, the absence of a control group and the absence of validated measurement tools, the observed positive effects of attending movement therapy center on motor performance and psychosocial development confirm in a naturalistic environment what has been shown in context of clinical trials or quasi-experimental studies. These results are not conclusive. They warrant further, rigorous investigation using validated instruments, independent assessors, and control groups.

Scholarly training objectives and requirements for paediatric residents in Canada.

In the absence of national standards for scholarly requirements, paediatric resident training varies significantly across Canadian programs. This variability may contribute to significant differences in trainee experiences and productivity. A panel of coordinators of paediatric resident research programs from across Canada met in 2014, to share experiences and identify barriers to successful resident scholarly activity. A survey of all programs was completed in 2015. A scoping review and series of meetings led to the development of a proposed list of expectations, timelines for successful completion and consequences for not completing a scholarly project. We propose a harmonized list of scholarly competencies and activities for paediatric residents in Canada to accomplish before completing their training. We also propose that programs implement standardized timelines and consequences in the event that a resident does not meet their program's scholarly expectations.

Pilot Testing a Robot for Reducing Pain in Hospitalized Preterm Infants.

Optimizing neurodevelopment is a key goal of neonatal occupational therapy. In preterm infants, repeated procedural pain is associated with adverse effects on neurodevelopment long term. Calmer is a robot designed to reduce infant pain. The objective of this study was to examine the effects of Calmer on heart rate variability (HRV) during routine blood collection in preterm infants. In a randomized controlled pilot trial, 10 infants were assigned to either standard care ( n = 5, facilitated tucking [FT]) or Calmer treatment ( n = 5). HRV was recorded continuously and quantified using the area (power) of the spectrum in high and low frequency (HF: 0.15-0.40Hz/ms2; LF: 0.04-0.15 Hz/ms2) regions. Changes in HRV during three, 2-min phases (Baseline, Heel Poke, and Recovery) were compared between groups. Calmer infants had 90% greater parasympathetic activation ([PS] reduced stress) during Baseline, 82% greater PS activation during Poke, and 24% greater PS activation during Recovery than FT infants. Calmer reduced physiological preterm infant pain reactivity during blood collection.

Nutritional management of phenylalanine hydroxylase (PAH) deficiency in pediatric patients in Canada: a survey of dietitians' current practices.

BACKGROUND: Phenylalanine hydroxylase (PAH) deficiency is one of 31 targeted inherited metabolic diseases (IMD) for the Canadian Inherited Metabolic Diseases Research Network (CIMDRN). Early diagnosis and initiation of treatment through newborn screening has gradually shifted treatment goals from the prevention of disabling complications to the optimization of long term outcomes. However, clinical evidence demonstrates that subtle suboptimal neurocognitive outcomes are present in the early and continuously diet-treated population with PAH deficiency. This may be attributed to variation in blood phenylalanine levels to outside treatment range and this, in turn, is possibly due to a combination of factors; disease severity, dietary noncompliance and differences in practice related to the management of PAH deficiency. One of CIMDRN's goals is to understand current practices in the diagnosis and management of PAH deficiency in the pediatric population, from the perspective of both health care providers and patients/families. OBJECTIVES: We investigated Canadian metabolic dietitians' perspectives on the nutritional management of children with PAH deficiency, awareness of recently published North American treatment and nutritional guidelines in relation to PAH deficiency, and nutritional care practices within and outside these guidelines. METHODS: We invited 33 dietitians to participate in a survey, to ascertain their use of recently published guidelines and their practices in relation to the nutritional care of pediatric patients with PAH deficiency. RESULTS: We received 19 responses (59% response rate). All participants reported awareness of published guidelines for managing PAH deficiency. To classify disease severity, 89% of dietitians reported using pre-treatment blood phenylalanine (Phe) levels, alone or in combination with other factors. 74% of dietitians reported using blood Phe levels ≥360 µmol/L (6 mg/dL) as the criterion for initiating a Phe-restricted diet. All respondents considered 120-360 µmol/L (2-6 mg/dL) as the optimal treatment range for blood Phe in children 0-9 years old, but there was less agreement on blood Phe targets for older children. Most dietitians reported similar approaches to diet assessment and counseling: monitoring growth trends, use of 3 day diet records for intake analysis, individualization of diet goals, counseling patients to count grams of dietary natural protein or milligrams of dietary Phe, and monitoring blood Phe, tyrosine and ferritin. CONCLUSION: While Canadian dietitians' practices in managing pediatric PAH deficiency are generally aligned with those of the American College of Medical Genetics and Genomics (ACMG), and with the associated treatment and nutritional guidelines from Genetic Metabolic Dietitians International (GMDI), variation in many aspects of care reflects ongoing uncertainty and a need for robust evidence.

Glucose control and autonomic response during acute stress in youth with type 1 diabetes: A pilot study.

BACKGROUND: Type 1 diabetes (T1D) is a chronic source of metabolic and neuropsychological stress, which may eventually lead to autonomic neuropathy and other complications related to micro- and macro-vasculopathies. We aimed to investigate the relationship between T1D chronic stress and autonomic response to acute stress testing that was expected being affected by chronic stress. METHODS: Twenty youths with confirmed diagnosis of T1D were assessed. Chronic stress assessment included hemoglobin A1c (HbA1c) ≥7.5%, psychological stress assessed by perceived stress scale (PSS), hypoglycemic events, and proinflammatory cytokines. The acute stress testing used standardized stress video games. Autonomic response to acute stress was assessed by the amplitude and direction of changes in heart rate variability. Analyses determined correlations between changes in parasympathetic nervous system during stress testing and chronic diabetes stressors. RESULTS: A strong correlation was found between the amplitude of high frequency (HF) changes and HbA1c values (ρ = 0.74, P < .001). Youths with HbA1c ≥7.5% showed a larger amplitude of HF changes during acute stress (49% vs 16%, P < .001) and a higher PSS score (22.5 vs 19.0, P = .003), compared to those with HbA1c <7.5%. Additionally, among youths with HbA1c ≥7.5%, those with positive changes in HF had a lower level of IL-8 than those with negative changes (5.40 vs 7.85 pg/mL, P = .009). CONCLUSIONS: Study findings support the need for better understanding the health effects of stress-related autonomic dysfunction in youth with T1D.

Effect of Mobile Phone Text Message Reminders on Routine Immunization Uptake in Pakistan: Randomized Controlled Trial.

BACKGROUND: Improved routine immunization (RI) coverage is recommended as the priority public health strategy to decrease vaccine-preventable diseases and eradicate polio in Pakistan and worldwide. OBJECTIVE: The objective of this study was to ascertain whether customized, automated, one-way text messaging (short message service, SMS) reminders delivered to caregivers via mobile phones when a child is due for an RI visit can improve vaccination uptake and timelines in Pakistan. METHODS: This was a randomized controlled trial, conducted in an urban squatter settlement area of Karachi, Pakistan. Infants less than 2 weeks of age with at least one family member who had a valid mobile phone connection and was comfortable receiving and reading SMS text messages were included. Participants were randomized to the intervention (standard care + one-way SMS reminder) or control (standard care) groups. The primary outcome was to compare the proportion of children immunized up to date at 18 weeks of age. Vaccine given at 6, 10, and 14 weeks schedule includes DPT-Hep-B-Hib vaccine (ie, diphtheria, pertussis, and tetanus; hepatitis B; and Haemophilus influenza type b) and oral poliovirus vaccine (OPV). Data were analyzed using chi-square tests of independence and tested for both per protocol (PP) and intention-to-treat (ITT) analyses. RESULTS: Out of those approached, 84.3% (300/356) of the participants were eligible for enrollment and 94.1% (318/338) of the participants had a working mobile phone. Only children in the PP analyses, who received an SMS reminder for vaccine uptake at 6 weeks visit, showed a statistically significant difference (96.0%, 86/90 vs 86.4%, 102/118; P=.03).The immunization coverage was consistently higher in the intervention group according to ITT analyses at the 6 weeks scheduled visit (76.0% vs 71.3%, P=.36). The 10 weeks scheduled visit (58.7% vs 52.7%, P=.30) and the 14 weeks scheduled visit (31.3% vs 26.0%, P=.31), however, were not statistically significant. CONCLUSIONS: Automated simple one-way SMS reminders in local languages might be feasible for improving routine vaccination coverage. Whether one-way SMS reminders alone can have a strong impact on parental attitudes and behavior for improvement of RI coverage and timeliness needs to be further evaluated by better-powered studies and by comparing different types and content of text messages in low-and middle-income countries (LMICs).
