Therefore, in this study, the authors aimed at clarifying actual situations of sleep and stress of middle age males living in shelters for a long period in each of emergency temporary houses and post-earthquake public houses. For 5 males who moved from emergency temporary houses to post-earthquake public houses, their objective and subjective sleep states were measured with Actigraph and PSQI, respectively. Furthermore, their objective and subjective stresses were measured with saliva stress biomarkers and GHQ28, respectively. Their data were analyzed by paired t-test. As result, in comparison between the life in the emergency temporary houses and post-earthquake public houses, significant variation was not recognized in their objective sleep states and saliva stress biomarkers though their subjective sleep and subjective stress were significantly worsened after moving to the post-earthquake public houses.展开更多

Methods: The study included patients admitted to the Department of Neurology at our hospital between September 2020 and August 2021. An Actigraph device was fitted to patients’ wrist and their beds to measure the amount of light received and sleep quality. Patients were divided into three groups: bed with a window, aisle bed with a false window, and aisle bed without a window. Mean sleep efficiency (%), mean steps (per day), and the amount of light (lux) received by the patients and beds were measured. Results: Valid data were obtained for 48 participants (median age, 66.5 years). There were 23 patients in beds with a window, 13 patients in aisle beds without a false window, and 12 in aisle beds with a false window. No statistically significant differences were found in terms of mean sleep efficiency, number of steps taken, and the amount of light received by the patients (P > 0.05);however, difference in the mean amount of light received by the beds at the location of the bed was statistically significant (P Conclusion: The amount of light that the patient receives is not necessarily affected by the location of the bed or the presence of a false window.展开更多

Twenty-six healthy adult persons (HPs) in their 20 s - 40 s met the inclusion criteria, and 16 persons (27.6 ± 8.2 years old) completed the research procedure. Of 70 persons with dementia (PDs) residing at the one geriatric health services facilities, only 24 persons met the inclusion criteria, and only nine (N = 9, 83.44 ± 9.45 years old) completed the procedure. Actigraph and ambulatory electrocardiographic instruments measuring autonomic nervous activity were attached to the subjects for 24 hours. Activities and behaviors of PDs and HPs were observed by clinically experienced staff nurses and care workers. High frequency (HF) power indicating parasympathetic activity and LF/HF ratio indicating sympathetic activity were calculated. When awake, PDs’ LF/HF ratio was significantly lower than HP’s (Z = -2.60, p < 0.01), showing significant differences in the LF/HF ratios between waking and sleeping, more than those of the PDs (p < 0.001). Similarly, when awake, significant positive correlations were observed in the LF/HF ratio and actigraph activity count (AC) in 11 HPs and 3 PDs (range r = 0.17 to 0.49, p < 0.05);however, significant negative correlation was found in HF and AC of 12 HPs and 3 PDs (range r = -0.55 to -0.18, p < 0.05). While sleeping, significant positive correlations were observed in LF/HF and AC of 3 HPs and 1 PD (range r = 0.35 to 0.42, p < 0.05) and significant negative correlation was found in the HF and AC of 1 HP (r= -0.32, p < 0.001) and 1 PD (r = -0.32, p < 0.05). The mean value of LF/HF in a wakeful state was significantly lower for PDs than HPs. Combined results of behavioral observation, actigrapy and heart rate variability (HRV) analyses suggested that PDs showed positive correlations between LF/HF and AC in a wakeful state. Compared to those who showed no positive correlation, they did not require much nursing care.展开更多

Sleep measu...The aim of the study is to examine nocturnal sleep measures of healthy and well developed pre-term infants by birth weight when they were averaged 15 corrected months and became elementary school children. Sleep measures were collected by actigraphs (Micro-mini RC, Ambulatory Monitoring Inc., New York, USA). Nocturnal sleep quality of children born as extremely low birth weight (ELBW) was significantly inferior with that of children born as very low birth weight (VLBW) at 15 corrected months [number of night waking: 6.0 (4.5 - 8.0), ELBW 8.5 (7.0 - 10.3) (Z = 2.47, p < 0.01), wake after sleep onset: VLBW 99.0 (73.0 - 115.0) min, ELBW 146.5 (94.8 - 171.3) min (Z = 2.89, p < 0.01)]. However, these measures did not show any significant differences by birth weight at second data collection period [number of night waking: VLBW 0.0 (0.0-1.0), ELBW 1.0 (0.0 - 2.5) (Z = —0.62, n.s.), wake after sleep onset: VLBW 16.0 (8.0 - 27.0) min, ELBW 15.0 (6.0 - 32.5) min (Z = 0.00, n.s.)]. It was assumed that nocturnal measures were affected by the birth weight at the age of 15 corrected months in ELBW infants, but could not predict the future sleep problems at this point.展开更多
文摘目的调查维持性血液透析(maintenance hemodialysis,MHD)患者日常体力活动水平及其影响因素,以期为MHD患者体力活动干预性研究和临床实践提供参考。方法采用便利抽样的方法,选取2024年2月─6月上海交通大学医学院附属仁济医院、上海市浦东新区浦南医院、上海交通大学医学院附属同仁医院血液净化中心进行MHD患者作为研究对象。采用一般资料调查表、疲乏、阻力、耐力、疾病、体质量减轻(fatigue、resistance、ambulation、illnesses、loss of weight,FRAIL)量表及社会支持评定量表对其进行调查,以ActiGraph GT3X加速度计客观评估患者体力活动状况。采用配对t检验分析MHD患者透析日及非透析日活动差异,以Logistic回归分析探索影响患者体力活动的因素。结果参与本研究的184例MHD患者中,仅52例(28.3%)体力活动量达到指南推荐水平;非透析日患者低、中等、高强度体力活动水平及步数均高于透析日(χ^(2)=33.686、19.230、4.390、34.567,P<0.001、<0.001、0.037、<0.001)。年龄越大(β=-1.650,95%CI:0.087~0.424,P<0.001)、衰弱程度越严重(β=-1.165,95%CI:0.048~0.763,P=0.019)的患者体力活动水平越低;社会支持水平越高(β=2.385,95%CI:0.997~118.345,P=0.050)的患者体力活动水平越高。结论MHD患者日常体力活动达标率较低,且透析日体力活动量更低。在未来针对该人群的体力活动干预与实践中,应重点关注年龄较大的患者群体,主动防治衰弱、发挥社会支持的正向影响作用,以期优化躯体功能、改善生活质量。
