Chronic non-communicable diseases(NCDs)represent a significant impediment to improve life expectancy and remain a focal point in global public health and disease prevention efforts.24-hour movement behaviors,which include sleep,sedentary behavior(SED),and physical activity,underscore the inherent connections between different daily activities and the comprehensive impact of overall movement patterns on health.Evidence suggested that modifying patterns of 24-hour movement behaviors can aid in preventing and attenuating the progression of NCDs.This study systematically delineated the concept,evolution,analytical methods,and intrinsic associations of 24-hour movement behaviors,emphasizing their pivotal role in the prevention and management of NCDs such as obesity,mental disorders,cardiovascular diseases,diabetes,and renal diseases.Future research endeavors should focus on refining methodologies,broadening study populations,developing research tools,and exploring precise intervention strategies and interdisciplinary approaches to comprehensively enhance the effectiveness of NCDs prevention and management from a temporal perspective.Such efforts are poised to provide substantive guidance and support for public health practices. 展开更多

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. 展开更多

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. 展开更多

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. 展开更多

Facing competition from Web-based information service development, academic librarians need to find ways to attract more users to the physical library buildings. This study investigated user needs and library management concerns for a 24/7 service through two surveys: 1) User feedback survey at Seton Hall University Library, and 2) Survey of Academic Library Deans and Directors in the USA. Based on these two surveys, the paper not only discussed the current status of libraries open 24/7 in the USA and showed the demographics of users of the 24/7 service at Seton Hall University, it also stated reasons to use the 24/7 service. In addition, the paper revealed library management concerns of the24/7 service. Three implications, which have been guided by Scott Bennett's theory of learning commons for planning library space, were drawn from the findings in this paper. 展开更多

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. 展开更多

目的:探讨夜间血压下降与开角型青光眼和正常眼压性青光眼患者视神经损伤进展的关系。方法:对我院眼科门诊确诊的开角型青光眼和正常眼压性青光眼患者51例51眼分别进行视野、OCT检查,进行平均视神经纤维层厚度、24h动态血压监测、24h眼... 目的:探讨夜间血压下降与开角型青光眼和正常眼压性青光眼患者视神经损伤进展的关系。方法:对我院眼科门诊确诊的开角型青光眼和正常眼压性青光眼患者51例51眼分别进行视野、OCT检查,进行平均视神经纤维层厚度、24h动态血压监测、24h眼压监测等检查,分析夜间血压过度下降与视野进展率的关系。结果:根据夜间血压下降值(dip)进行分组,三组间有显著性差异的数值为平均缺损(MD)差值(P=0.032)、眼压峰值(P=0.003)、视野缺损计分差值(P=0.041)。在视野缺损进展组、视野缺损改善组、视野缺损不变组间,dip有显著性差异(P=0.028)。视野缺损进展组夜间血压下降值明显高于其他两组。夜间血压过度降低组视野缺损进展率明显高于不过度降低组(视野缺损进展率分别为50%,7%)。影响视神经纤维层(RNFL)厚度的相关因素为夜间最低平均动脉压和dip(P=0.011,P=0.032,R2=0.081);影响MD值的相关因素为眼压波动(P=0.026,R2=0.115);影响模式标准差(PSD)值的相关因素为眼压波动和dip(P=0.020,P=0.044,R2=0.141)。结论:与开角型青光眼相比,正常眼压性青光眼患者中夜间血压过度下降的发生率较高。夜间血压过度降低组中视野损伤进展明显。视野缺损进展组夜间血压降低更明显。眼压波动与dip是正常眼压性青光眼和高眼压开角型青光眼的患者视神经损伤与视野缺损高危因素。 展开更多
