ObjectiveThe aim of this research was to assess the effect of social jetlag (SJL) and its interaction with partial sleep deprivation on resting-state brain activity using the fractional amplitude of low-frequency fluctuation (fALFF) during free-living conditions.MethodsA total of 28 normal weight healthy subjects were enrolled in four study groups (with SJL [with sleep deprivation and without sleep deprivation] and without SJL [with sleep deprivation and without sleep deprivation]), matched 1:1:1:1 for age, gender, and body mass index (BMI). Resting-state functional magnetic resonance imaging (fMRI) scans were collected with SIEMENS 3T scanner while subjects were in a fasting state.ResultsParticipants with SJL had significantly higher fALFF values in right lingual gyrus and right putamen and significantly lower fALFF values in left and right inferior parietal lobe in comparison with participants without SJL and without sleep deprivation. Subjects with sleep deprivation had significantly higher fALFF in the thalamus and left superior frontal gyrus. In those with both SJL and sleep deprivation, we observed higher fALFF values in right Brodmann Area (BA)18 and lower values in left and right parietal inferior lobe. Subjects with SJL alone had significantly lower fALFF values in left frontal mid gyrus (BA6) than those with sleep deprivation alone.ConclusionsSJL was associated with altered resting-state brain activity in regions that have been shown to be involved in hedonic feeding. The effect of SJL was independent of effects induced by short sleep duration. These alterations might represent the substrate for the increased risk of obesity observed in those with SJL. 相似文献

Context: Bracing is one of the most important treatment approaches that have been utilized in patients with scoliosis. Boston brace used to manage a scoliotic curve especially in lumbar and thoracolumbar areas.Objective: The aim of this review was to evaluate the efficiency of Boston brace to control the progression of the curve based on the available literature.Methods: A search was carried out using the following databases including Scopus, ISI Web of knowledge, PubMed, Ebsco, and Embasco. The key words used for the search were Boston brace, Boston orthosis which were used in combination with scoliosis. Articles identified were screened based on titles and abstracts. The quality of the studies was evaluated using Black and Down tool. Data were summarized based on PICO style.Results: Based on the aforementioned key words, 18 papers were selected, in which 7 studies focused on efficiency of Boston brace, 3 papers focused on quality of life, 5 papers on finite element analysis and 3 papers on comparison of efficiency of Boston with other available braces. The quality of the selected studies varied between 14 and 21.Conclusion: The results of most of the studies support the efficiency of this brace to control the progression of scoliotic curve, especially for the curve between T6 and L2. The efficiency of this brace may be due to its rigid structure and also location and direction of the straps. 相似文献

目的:分析经右外侧小切口剖胸矫治合并需行心底部操作的室间隔缺损(VSD)手术方法及临床疗效。方法:比较经右外侧小切口剖胸矫治需行心底部复杂操作(干下型VSD或右心室流出道狭窄或主动脉瓣下狭窄)的VSD 84例(A组),和经右外侧小切口剖胸矫治不合并心底部畸形的VSD450例(B组),A组在矫治心内畸形的同时需切开主动脉、肺动脉或者右心室流出道。通过对比体外循环时间、主动脉阻断时间、术后机械通气时间、术后引流量、监护室时间以及术后住院时间,观察在心底部进行复杂操作对手术的影响和治疗效果。结果:尽管A组比B组需要更长的体外循环时间[(60.68±16.12)vs.(47.07±16.55)分,P<0.05]和主动脉阻断时间[(37.68±12.84)vs.(25.16±12.60)分,P<0.05],但在术后评价指标,机械通气时间9.18vs.8.51小时、术后引流量(96.98 vs.92.30m L)、监护室停留时间(1.44 vs.1.40)天、术后住院时间[(7.00±1.76)vs.(7.06±2.23)天,P<0.05]。两组均无死亡及严重并发症。A组有3例血痰、肺部感染1例,室上性心动过速1例。B组有9例患儿术后血痰,2例肺部感染,临时起搏器4例。结论:经右外侧小切口剖胸矫治VSD的同时行心底部复杂操作安全可行。 相似文献
