Associations between meeting 24-hour movement guidelines and quality of life among children and adolescents with autism spectrum disorder

Background:The Canadian 24-hour movement behavior(24-HMB)guidelines suggest that a limited amount of screen time use,an adequate level of physical activity(PA),and sufficient sleep duration are beneficial for ensuring and optimizing the health and quality of life(QoL)of children and adolescents.However,this topic has yet to be examined for children and adolescents with autism spectrum disorder(ASD)specifically.The aim of this cross-sectional observational study was to examine the associations between meeting 24-HMB guidelines and several QoLrelated indicators among a national sample of American children and adolescents with ASD.Methods:Data were taken from the 2020 U.S.National Survey of Children’s Health dataset.Participants(n=956)aged 617 years and currently diagnosed with ASD were included.The exposure of interest was adherence to the 24-HMB guidelines.Outcomes were QoL indicators,including learning interest/curiosity,repeating grades,adaptive ability,victimization by bullying,and behavioral problems.Categorical variables were described with unweighted sample counts and weighted percentages.Age,sex,race,preterm birth status,medication,behavioral treatment,household poverty level,and the educational level of the primary caregivers were included as covariates.Odds ratio(OR)and 95%confidence interval(95%CI)were used to present the strength of association between adherence to 24-HMB guidelines and QoL-related indicators.Results:Overall,452 participants(45.34%)met 1 of the 3 recommendations,216(22.65%)met 2 recommendations,whereas only 39 participants(5.04%)met all 3 recommendations.Compared with meeting none of the recommendations,meeting both sleep duration and PA recommendations(OR=3.92,95%CI:1.639.48,p<0.001)or all 3 recommendations(OR=2.11,95%CI:1.034.35,p=0.04)was associated with higher odds of showing learning interest/curiosity.Meeting both screen time and PA recommendations(OR=0.15,95%CI:0.040.61,p<0.05)or both sleep duration and PA recommendations(OR=0.24,95%CI:0.070.87,p<0.05)was associated with lower odds of repeating any grades.With respect to adaptive ability,participants who met only the PA recommendation of the 24-HMB were less likely to have difficulties dressing or bathing(OR=0.11,95%CI:0.020.66,p<0.05)than those who did not.For participants who met all 3 recommendations(OR=0.38,95%CI:0.150.99,p=0.05),the odds of being victimized by bullying was lower.Participants who adhered to both sleep duration and PA recommendations were less likely to present with severe behavioral problems(OR=0.17,95%CI:0.040.71,p<0.05)than those who did not meet those guidelines.Conclusion:Significant associations were found between adhering to 24-HMB guidelines and selected QoL indicators.These findings highlight the importance of maintaining a healthy lifestyle as a key factor in promoting and preserving the QoL of children with ASD.

Interdialytic 24-Hours Ambulatory Blood Pressure versus Dialysis Unit Blood Pressure for the Diagnosis of Electrocardiographic-Left Ventricular Hypertrophy in Chronic Hemodialysis Black Patients

Background and Aim: In hemodialysis patients, 24-hours interdialytic ABPM better detects TOD than dialysis unit blood pressure. Therefore, the present study was aimed to assess the diagnostic performance of 24-hours ABPM vs. dialysis unit BPs for the diagnosis of ECG-LVH in steady state chronic hemodialysis black patients. Methods: From March 31 to September 30, 2018, interdialytic ABPM was performed after a mid-week hemodialysis session for 24 hours using a Spacelab 90207 ABPM monitor in the non-access arm in 45 stable chronic hemodialysis black patients (age ≥ 20 years, hemodialysis for at least 3 months and informed consent) attending 3 hemodialysis centers in Kinshasa. Ambulatory BP was recorded every 20 minutes during the day (6 AM to 10 PM) and every 30 minutes during the night (10 PM to 6 AM). ECG-LVH was defined using Cornell product criteria. ROC curve method was used to assess the performance of dialysis unit BPs vs. interdialytic 24-hours ABPM in diagnosing ECG-LVH. P 0.05 defined the level of statistical significance. Results: Whatever the method of BP measurement, all the SBP values were related to ECG-LVH with similar AUC and overlapping 95% CI;however, they were not significantly different from each other. 24-hours interdialytic ambulatory SBP (AUC 0.748;95% CI 0.58 - 0.94) had the highest area under the curve. Conclusion: The present study showed that although all the two BP measurement methods equally detected ECG-LVH, 24-hours ABPM tended to have the highest diagnostic performance.

The nurses’ voice of working in a newly established community based 24-hour support center for people with psychiatric disabilities

This study explores the perceptions of a small group of nurses working at a newly established 24-hour community-based service enter (SC) for users with psychiatric disability using a qualitative approach. Since the mental health reform in Sweden in 1995 where the communities (in Sweden called municipalities) were given the responsibility to establish service and support to people with severe psychiatric disabilities, they have struggled in finding suitable forms of these kinds of areas. In 2010, this led to the creation and development of a new center aiming to provide services and support based on the expressed needs of people with physchiatric disability in a community located in southern Sweden. During 2011, a total of three group interviews were performed to capture the employed nurses’ perceptions of this newly established SC. The interview texts were analyzed by way of qualitative content analysis. A first reading of the interview texts revealed that the nurses’ perceptions of the service center were unwaveringly positive but that their beliefs about who the specific target group were differed. The main finding was summarized by the theme: Making a difference—on an individual, professional, and organizational level. The sub themes were: 24-hour availability, unclear assignment, and preventing mental illness. The findings indicate a need for a community round-the-clock service center in this Swedish community and a more clear definition of the target group.

The lived experience of a 24-hour support center for persons with psychiatric disabilities: Making me feel almost like an ordinary person

This study illuminates nine psychiatric disabled persons’ lived experience of a newly established community-based service center open around the clock. This new 24-hour support center (SC) was established in 2011 in a Swedish community to better match and facilitate the disabled persons’ needs. In order to illuminate the disabled person’s experiences individual interview was performed. A phenomenological-hermeneutical method inspired by Paul Ricoeur was used to interpret the texts. After a naive reading, a structural analysis revealed two themes: 1), becoming aware of myself as a person, and 2) having a lifeline and belongingness. The comprehensive understanding was interpreted as meaning “Making me feel almost like an ordinary person”, which incorporated the person’s past with their present together with a direction for the future and hope for a more fulfilling life.

Association between endogenous cortisol level and the risk of central serous chorioretinopathy:a Meta-analysis

AIM： To assess the association between endogenous cortisol level and the risk of central serous chorioretinopathy（CSC）.METHODS： Case-control studies were systematically searched on PubM ed, Embase, Cochrane, China National Knowledge Infrastructure（CNKI） for publishes between January 1990 and July 2017 to assess the association between endogenous cortisol level and CSC. The main endpoints were serum cortisol level at 8 a.m. and 24-hour urine 17-hydroxysteroids level. We assessed pooled data using a random-effects model.RESULTS： Of 86 identified studies, 5 were eligible included in our analysis. The 5 studies included a total of 315 participants, of whom 187 had CSC. Statistically significant association was observed between serum cortisol level（summary SMD=0.77, 95%CI=0.55-0.99）, 24-hour urine 17-hydroxysteroids level（summary SMD=0.95, 95%CI=0.61-1.30）, and the risk of CSC.CONCLUSION： Endogenous cortisol level is associated with an increased risk of CSC. Combined treatment targeting the serum cortisol level at 8 a.m. and 24-hour urine 17-hydroxysteroids level can be a potential preventive strategy for individuals who are at risk of CSC and therapeutic strategy for patients with CSC.

Computed tomography perfusion and computed tomography angiography for prediction of clinical outcomes in ischemic stroke patients after thrombolysis

Cerebral blood perfusion and cerebrovascular lesions are important factors that can affect the therapeutic efficacy of thrombolysis.At present,the majority of studies focus on assessing the accuracy of lesion location using imaging methods before treatment,with less attention to predictions of outcomes after thrombolysis.Thus,in the present study,we assessed the efficacy of combined computed tomography（CT） perfusion and CT angiography in predicting clinical outcomes after thrombolysis in ischemic stroke patients.The study included 52 patients who received both CT perfusion and CT angiography.Patients were grouped based on the following criteria to compare clinical outcomes：（1） thrombolytic and non-thrombolytic patients,（2） thrombolytic patients with CT angiography showing the presence or absence of a vascular stenosis,（3） thrombolytic patients with CT perfusion showing the presence or absence of hemodynamic mismatch,and（4） different CT angiography and CT perfusion results.Short-term outcome was assessed by the 24-hour National Institution of Health Stroke Scale score change.Long-term outcome was assessed by the 3-month modified Rankin Scale score.Of 52 ischemic stroke patients,29 were treated with thrombolysis and exhibited improved short-term outcomes compared with those without thrombolysis treatment（23 patients）.Patients with both vascular stenosis and blood flow mismatch（13 patients） exhibited the best short-term outcome,while there was no correlation of long-term outcome with CT angiography or CT perfusion findings.These data suggest that combined CT perfusion and CT angiography are useful for predicting short-term outcome,but not long-term outcome,after thrombolysis.

Reproductive Behaviors and Pairing Modes of Odontotermes fomosanus(Shiraki)Alates

[ Objectives ] To study the reproductive behaviors and the effect of different pairing modes on the developmental status of incipient colonies＇of Odontote- rmes fomosanus （Shiraki）. [ Methods ] We observed the reproductive behaviors of male alates, female Mates and mated alates respectively. Male and female Mates had 9 pairing modes and founded 170 incipient colonies under laboratory conditions. The effect of pairing mode on incipient colonies＇ developmental status was ana- lyzed. [ Results ] Two peaking hours of mating activity within the daily circadian rhythm of Mate activity appeared from 09：00 to 10：00, and from 21：00 to 22：00, respectively. Courtship behavior before mating consisted of touching with antennae, connecting into a ring （head-to-end）, and licking. The reproductive behavior （ calling, pairing, tandem, mating and oviposition） of nestmate pairs was different to that of non-nestmate pairs. The pairing time of non-nestmate pairs was signifi- candy longer than that of alates paired with siblings （P 〈 0.05 ）. The non-swarming alates could mate with swarming or non-swarming Mates and lay fertile eggs which hatched successfully. However, the survival rate of colonies founded by non-swarming alates was very low. The death rate of incipient colonies was in the range of 0.61% -0. 99% after three months, while the death rate of the colonies founded by swarming alates was in the range of 0.22% -0.58%. Females that had been experimentally prevented from mating could lay eggs, but the eggs did not hatch. [ Conclusion] There are two distinct hourly peaks of mating activity within each 24 hour period. Incipient colonies founded by outbreeding have the highest probability of survival.

Nutritional Biomarker Analyses for Hypertension-Related Risk Assessment and Control

A simple method to collect 24-hour urine (24U) by sampling 2.5% of the voided urine each time was developed for analyzing the biomarkers of the intakes of salt (NaCl), vegetables and grains (K, Mg), soys (isoflavones), sea-foods (taurine), protein (urea nitrogen) etc. This method was applied to WHO-coordinated CARDIAC (Cardiovascular Diseases and Alimentary Comparison) study covering 61 populations in 25 countries, and revealed significant positive associations of Na or Na/K with blood pressure (BP) and stroke mortality and significant inverse associations of isoflavones or taurine with coronary heart disease (CHD) mortality, indicating the adverse effect of salt intake on BP and stroke and beneficial effect of soy or sea food intakes on CHD. Furthermore, higher urinary taurine and/or Mg excretions were associated with significantly lower risks of metabolic syndromes such as obesity, hypertension and hypercholestelomia. 24U collections were useful to prove nutritional improvement by intervention studies for observing soy intake effect on BP and atherogenic index in Japanese immigrants living in Brazil, and in Australian Aboriginals, for observing taurine effect on BP in Tibetans and for confirming soy and fish effects on the risks of metabolic syndromes in Japanese businessmen. 24U collection was utilized for population strategy to reduce salt and to increase soy intake in 5.6 million people of Hyogo Prefecture. A simple method for 24U collection has enabled us to utilize nutritional biomarkers for hypertension-related disease risk analyses, and to apply objective nutritional intake estimation to intervention studies as well as to population strategy for nutritional improvement, and therefore, the methodology will contribute to hypertension-related disease prevention and global health promotion.

Can spot urine measurement be a substitute for 24-hour urine measurement to estimate sodium intake in adolescents?

Importance:Several methods have been established in recent decades that allow use of spot urine to estimate dietary sodium intake.However,their accuracies have been controversial in children.Objective:To validate the performance of three commonly used methods-the Kawasaki,Tanaka,and International Cooperative Study on Salt,Other Factors,and Blood Pressure(INTERSALT)methods.Additionally,this study explored the accuracies of the Tanaka and INTERSALT methods by using spot urine samples taken at four separate times.Method:Forty-one adolescents aged 14 to 16 years completed two non-consecutive 24-hour urine collections and their mean values were used as reference data.The second-morning urine was used for assessment with the Kawasaki method;a casual spot urine and spot urine samples taken at four separate times(morning,afternoon,evening,and overnight)were used for assessment with the Tanaka and INTERSALT methods.Results:The mean differences were 1801 mg,542 mg,47 mg,and-31 mg for the Kawasaki,Tanaka,INTERSALT 1(with potassium),and INTERSALT2(without potassium)methods with their required spot urine,respectively.The proportions of relative difference levels within±10%were 4.9%for the Kawasaki method,19.5%for the Tanaka method,36.6%for the INTERSALT 1 method,and 36.6%for the INTERSALT2 method.Interpretation:The INTERSALT method seemed to provide minimally biased estimations of mean population sodium intake with casual spot urine.However,there is a need to be cautious regarding inconsistencies in estimation among different levels of sodium intake.The methods assessed in this study were unable to accurately estimate sodium intake at the individual level.

Can pH Monitoring Predict Gastric Emptying Measured by ¹³C-Acetate Breath Test in Gastroesophageal Reflux with Neurological Impairment?

Introduction: Delayed gastric emptying (DGE) often occurs in patients with gastroesophageal reflux (GER) due to neurological impairment (NI). 13C has been used as an alternative tool for measuring the gastric emptying rates. The aim of this study was to predict gastric emptying in children with GER using 13C-acetate breath test (ABT) by 24-hour pH monitoring. Methods: Nineteen patients were divided into 2 groups: a DGE group with NI (14 patients), and normal-emptying group without NI (5 patients). The liquid test meal consisted of RacolTM (5 ml/kg) mixed with 13C-acetate (50 mg for infants, 100 mg for children, and 150 mg for adolescents). 13CO2 was measured using a gas chromatograph-isotope ratio mass spectrometer. The results are expressed as the % of 13C expired per hour and cumulative 13C excretion over a 3-hour periods including the parameters of half excretion and lag time. Results: The mean half excretion time was 1.762 hour in the DGE group and 1.095 hour in the normal-emptying group (P = 0.0196). The mean lag time was 0.971 hour in the DGE group and 0.666 hour in the normal-emptying group (P = 0.0196). Therefore, DGE was significantly more prevalent in the DGE compared to the normal-emptying group. The percentage of the time when the pH was less than 4 on 24-hour esophageal pH monitoring was 21.6% ± 9.2% in the DGE group and 28.5% ± 11.6% in the normal-emptying group (P = 0.4634). Conclusion: The percentage of time when the pH is less than 4 on 24-hour pH monitoring cannot predict DGE measured by the 13C-ABT in GER.

Blood Pressure Variability and Its Relationship with Cognitive Function in Elderly Patients with Essential Hypertension and Type 2 Diabetes

Objective: To investigate blood pressure variability of Elder hypertensives with type 2 diabetes and its relationship with cognition. Methods: A total of 143 elderly hypertensives were enrolled and divided into diabetic group (59 cases) and non-diabetic group (84 cases). The difference of general clinical characteristics, biochemical parameters, carotid ultrasound, a neuropsychological Scales and 24-hour ambulatory blood pressure (24hABPM) parameters between the two groups of subjects were compared. Then, the two groups (diabetic group and non-diabetic group) were further divided into (Mild cognitive dysfunction) subgroup (MMSE>26) and normal cognition subgroup (MMSE≤26), respectively. On the basis of MMSE scores, the difference of the parameters of ABPM between the two subgroups was analyzed. Results: Compared with the control group, 24hSBP, 24hPP, dSBP, dPP, nSBP, nPP, 24hSSD, dSSD, nSSD, 24hSCV, dSCV and nSCV were significantly higher in the diabetic group (p<0.05). However, cognition was lower in the diabetic group. No significant difference was found in the circadian pattern of blood pressure between the two groups. 24hSSD, dSSD, nSSD, 24hSCV, dSCV, nSCV were significantly higher in the MCI subgroup than normal cognition subgroup in both diabetic and non-diabetic groups(p<0.05), and they were negatively associated with scores of MMSE, the correlation coefficient were -0.235,-0.246,-0.341,-0.158,-0.222,-0.238 (0.001≤P<0.05). Conclusion: The study showed that in the elderly with hypertension, the mean systolic blood pressure and blood pressure variability were both higher in the diabetic group, and the cognition was lower instead. Whether or not with diabetes, blood pressure variability was always higher in the MCI subgroup. Blood pressure variability increased in patients with diabetes, and was associated with cognitive decline.

Traffic load predictions for cellular networks:A comparative study based on deep learning

Prediction of the traffic load of cellular networks is important for network planning, load balancing, and operational optimization. In this paper, a comparative study of cellular traffic load prediction models based on deep learning is performed and a prediction method built on a multi-channel Gated Recurrent Unit(GRU) model is proposed. The proposed method uses multiple channels to extract the daily and weekly variation feature as well as the variation feature of the peak period of the BS load and can be used to provide 24-hour ahead predictions.Experimental results obtained from real dataset show that the proposed multi-channel model can effectively capture the temporal-variations of BS load and reduce the prediction error.Compared with conventional prediction algorithms such as Convolutional Neural Network(CNN), Long Short-Term Memory network, GRU and combination of CNN and GRU(CNN-GRU),the proposed model can achieve better prediction accuracies.
