Abstract Introduction Acupuncture is an alternative treatment for improving sleep quality and the effectiveness is thought to be optimized with an individualized approach resembling real practice. However, existing evidence is limited by methodological shortcomings due to blinding issues, standardized measures, and diagnostic procedures. It was of the present study’s interest to examine the efficacy and safety of semi-individualized acupuncture treatment on insomnia. Methods Adults with DSM-5 insomnia disorder (n = 140) were randomized with 1:1 allocation to a 4-week intervention traditional acupuncture (TA) or validated non-invasive sham acupuncture (SA). The selection of acupoints was semi-individualized by the acupuncturist. As the primary outcome, the sleep efficiency (SE) by sleep diary was assessed at baseline, 1-week posttreatment, and 5-week posttreatment. Other sleep parameters derived from sleep diary, the wrist-actigraphy-derived sleep parameters, insomnia symptom severity, anxiety, and depressive symptoms, as well as the health-related quality of life, were also evaluated. Results Although linear mixed-effect model revealed both groups did not attain significant difference in sleep-diary-derived SE and other outcome measures (all P > 0.05), TA promising effect on improving insomnia symptom (within-group effect size, d = 1.13 & 1.30 at 1-week & 5-week posttreatment respectively) and also a higher proportion of subjects achieved SE ≥ 85% compared with SA (55.6% versus 36.4% at week 9, P = 0.03). Besides, subjects in TA group reported significantly greater improvement in both the total sleep time (TST) derived from sleep diary and actigraph than those in the SA group at 1-week posttreatment (difference in mean changes from baseline: sleep diary = 22.0 min, p = 0.01; actigraphy =18.8 min, P = 0.02) but not 5-week posttreatment. Conclusion This study is the first to evaluate the effect of the TCM-theory-based individualized acupuncture on sleep using a sham-control design. A 4-week semi-individualized acupuncture is able to significantly increase total sleep time with few adverse events.

The Relationship

Abstract Study Objectives There is mixed evidence for the relationship between poor sleep and daytime fatigue, and some have suggested that fatigue is simply caused by lack of sleep. Although retrospective measures of insomnia and fatigue tend to correlate, other studies fail to demonstrate a link between objectively disturbed sleep and fatigue. The current study prospectively explored the relationship between sleep and fatigue among those with and without insomnia disorder. Methods Participants meeting Research Diagnostic Criteria for insomnia disorder (n = 33) or normal sleepers (n = 32) completed the Consensus Sleep Diary (CSD) and daily fatigue ratings for 2 weeks. Baseline questionnaires evaluated cognitive factors including unhelpful beliefs about sleep and rumination about fatigue. Hierarchical linear modeling tested the within- and between-participant relationships between sleep quality, total sleep time, and daily fatigue ratings. Mediation analyses tested if cognitive factors mediated the relationship between insomnia and fatigue. Results Self-reported nightly sleep quality significantly predicted subsequent daily fatigue ratings. Total sleep time was a significant predictor of fatigue within, but not between, participants. Unhelpful sleep beliefs and rumination about fatigue mediated the relationship between insomnia and fatigue reporting. Conclusions The results suggest that perception of sleep plays an important role in predicting reports of daytime fatigue. These findings could be used in treatment to help shift the focus away from total sleep times, and instead, focus on challenging maladaptive sleep-related cognitions to change fatigue perception.

Measuring sleep and sleep quality is an important diagnostic and monitoring tool, and a number of different methods for measurement have been developed over the last half-century. Two prevalent methods include wrist actigraphy and sleep diaries. Both methods can be applied in different circumstances, but both have strengths and weaknesses. This study aimed to identify the extent to which there is congruence in the scores achieved by each method of sleep measurement. Sixty-eight respondents were asked to wear a wrist actigraphy and complete a sleep diary over the course of five days. There was a significant difference between the mean scores achieved using each measurement method, with actigraphy scores indicating lower total sleep time (TST) than diaries. However, this difference was not consistently present when the scores were compared on a day by day basis. Participant adherence is likely to fluctuate over the course of a sleep study and may undermine the accuracy of sleep diaries.

Abstract Introduction This analysis assessed whether manually setting rest (i.e., time in bed) intervals prior to using a proprietary software package (Actiware, version 6.09) to analyze wrist actigraphy data improved estimates of total sleep time (TST) compared to polysomnography (PSG). Methods The Phillips Actiwatch 2 and PSG (reference method) were used to calculate TST on two separate nights in twelve men (age=28.3 ± 5.7). Participants had an 8-hour sleep opportunity on night one and a 5-hour sleep opportunity and on night two. Estimates of TST from actigraphy data were calculated using two scoring methods. For scoring method 1, we allowed the software to automatically choose rest intervals and then applied a proprietary algorithm to calculate TST. For scoring method 2, we manually entered rest intervals using a published decision tree that incorporates activity, light, event marker, and sleep diary data. After the rest intervals were set in method 2, the proprietary algorithm was applied to calculate TST. Mean bias and limits of agreement (LOA) from Bland-Altman plots compared TST derived from both actigraphy scoring methods to PSG estimates. Results On night 1 (n=8) TST measured by PSG was 398.4 ± 40.6 minutes, compared to 395.5 ± 70.9 minutes using actigraphy scoring method 1 and 396 ± 44.5 minutes using scoring method 2. Mean bias was similar when comparing both scoring methods to PSG, but the LOA were wider in method 1 compared to method 2 (method 1 vs. PSG: -2.9 [-110.4, 104.7]; method 2 vs. PSG: -2.4 [-66.5, 61.7]; minutes). On night 2 (n=12) TST determined by PSG was 283.3 ± 11.2 minutes, compared to 302.1 ± 84.4 minutes using actigraphy scoring method 1 and 273.1 ± 14.5 minutes using scoring method 2. Again, LOA for TST estimated by actigraphy scoring method 1 were wider compared to scoring method number 2 (method 1 vs. PSG: 18.8 [-136.9, 174.6]; method 2 vs. PSG: -10.2 [-35.1, 14.8]). Conclusion These data demonstrate that applying a decision tree to manually set time in bed intervals prior to running analyses in the software results in better agreement when estimating TST from wrist actigraphy compared to PSG.

Abstract Introduction Positive airway pressure (PAP) adherence definitions are independent of total sleep time (TST). When PAP efficacy is examined by biophysiologic outcomes in adults with obstructive sleep apnea (OSA), sensitivity and specificity of the measurement of PAP adherence/non-adherence is important. Methods A post-hoc analysis of experimental data: 1) investigated agreement among concurrently-measured objective PAP use, objective and subjective TST; 2) assessed untreated TST among adherers and non-adherers defined by CMS PAP adherence criterion and separately by proportion of TST on PAP criteria (≥65%, ≥75%, ≥85%). Objective TST was measured with wrist actigraphy and concurrent sleep diary on the first five days of PAP use. Objective five day PAP use (hours/night) was abstracted from full record. Analyses included descriptive and exploratory correlations. Results PAP-naïve adults (n=36; 76% male, 84% white) were middle-aged (51±10 years), with severe OSA (median AHI 31.1 events/hr), mean PAP use (371.5±85.4 min), mean objective and subjective TST (417.5±50.6 min, 439.6±58.1 min, respectively) from a single sleep center. Objective TST was correlated with concurrent objective PAP use (r=0.46) and with subjective TST (r=0.78). Eight percent (39mins) of objective TST was untreated among CMS-defined adherers, and 54.1% (216.8mins) of TST was untreated among CMS-defined non-adherers. When TST-on-treatment criteria were imposed (≥65%, ≥75%, and ≥85%, respectively), the percentage of untreated TST decreased among adherers, 5.2% (23 min), 4.3% (19 min), 0% (0 min) and among non-adherers, 42.8% (168 min), 41.2% (162 min), and 28.7% (118 min). From CMS to ≥85% of TST-on-treatment criteria, categorization as an adherer decreased from 89% (n=34) to 58% (n=22); non-adherer categorization increased from 5% (n=2) to 37% (n=14). Conclusion In the context of understanding biophysiological responses to PAP treatment, more sensitive and specific criteria for adherence and non-adherence is necessary. PAP use based on untreated TST is an opportunity to address this gap. Support The parent clinical trial was supported by NIH/NINR (R00NR011173; Sawyer PI)

Abstract Actigraphy is used as a validated measure of rest and sleep, however, there are reported differences in WASO in healthy individuals (Chinoy, 2021). Methods This study compares the sleep parameters from PSG with simultaneous overnight actigraphy on patients the night prior to MSLT. We also compare the actigraphy data collected on the week prior to the PSG with the patient’s sleep diary. 22 subjects, age 38.7 ± 3.1 years, BMI 23.5 ± 1.4 kg/m2, 40.1% male, 4 participants were treated with CPAP. Results WASO was found to be under estimated by actigraphy versus PSG (y=-0.957x+18.014, R2=0.51), there is an increase in underestimation beyond 18minutes. Our data also show on overestimation of sleep onset latency by actigraphy versus PSG when sleep latency is longer than 12 minutes (y=0.27x-12.04, R2=0.08). Total sleep time was perceived to be longer on the PSG night than the PSG data shows (y=0.68x-4.65, R2=0.21). Data demonstrated participants to overestimate their sleep period in their sleep diary compared to the actigraphy data (y=-0.87x+6.58, R2=0.21). T-tests showed a significant difference between WASO (minutes) detected by PSG and the actigraphy data (67.4 ± 8.9 vs 33.3 ± 3.9 p=0.0007). There were no other significant differences in the datasets. Conclusion Actigraphy uses activity data and light detection to estimate rest and sleep periods in wearers. Our data reflects expected differences reported in the literature of actigraphy data versus PSG due to the limitation of actigraphy being able to differentiate between sleep and motionless wakefulness.

Abstract Study Objectives We examined the night-to-night associations of evening use of alcohol, caffeine, and nicotine with actigraphically estimated sleep duration, sleep efficiency, and wake after sleep onset (WASO) among a large cohort of African American adults. Methods Participants in the Jackson Heart Sleep Study underwent wrist actigraphy for an average of 6.7 nights and completed concurrent daily sleep diary assessments to record any consumption of alcohol, caffeine, and nicotine within 4 hours of bedtime. Linear mixed-effect models were fit and adjusted for age, sex, educational attainment, body mass index, depression, anxiety, stress, and having work/school the next day. Results Eligible participants (n = 785) were an average of 63.7 years (SD: 10.6), and were predominantly female (67.9%). There were 5164 days of concurrent actigraphy and sleep diary data. Evening alcohol use was associated with that night’s lower sleep efficiency (−0.98% [95% CI: −1.67% to −0.29%], p = 0.005), but not with WASO or sleep duration. Evening nicotine use was associated with that night’s lower sleep efficiency [1.74% (95% CI: −2.79 to −0.68), p = 0.001] and 6.09 minutes higher WASO ([95% CI: 0.82 to 11.35], p = 0.02), but was not associated with sleep duration. Evening caffeine use was not associated with any of the sleep parameters. Conclusion Nicotine and alcohol use within 4 hours of bedtime were associated with increased sleep fragmentation in the associated night, even after controlling for multiple potential confounders. These findings support the importance of sleep health recommendations that promote the restriction of evening alcohol and nicotine use to improve sleep continuity.

Healthcare workers’ cognitive performances and alertness are highly vulnerable to sleep loss and circadian rhythms. The purpose of this study was to investigate the changes in sleep characteristics of intensive care unit (ICU) and non-ICU physicians. Actigraphic sleep parameters, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale and Hamilton Depression Rating Scale were evaluated for ICU and non-ICU physicians on the day before shift-work and on three consecutive days after shift-work. Total sleep time, sleep latency, wakefulness after sleep onset, total activity score, movement fragmentation index, sleep efficiency, daytime naps and total nap duration were also calculated by actigraph. In the ICU physicians, the mean Pittsburgh Sleep Quality Index score was significantly higher than the non-ICU physicians (P=0.001), however mean Epworth Sleepiness Scale scores were not found significantly different between the two groups. None of the scores for objective sleep parameters were statistically different between the groups when evaluated before and after shift-work (P >0.05). However in both ICU and non-ICU physicians, sleep latency was observed to be decreased within the three consecutive-day period after shift-work with respect to basal values (P <0.001). Total sleep time, total activity score and sleep efficiency scores prior to shift-work were significantly different from shift-work and the three consecutive-days after shift-work, in both groups. Working in the ICU does not have an impact on objective sleep characteristics of physicians in this study. Large cohort studies are required to determine long-term health concerns of shift-working physicians.

AbstractSleep studies in small-scale subsistence societies have broadened our understanding of cross-cultural sleep patterns, revealing the flexibility of human sleep. We examined sleep biology among BaYaka foragers from the Republic of Congo who move between environmentally similar but socio-ecologically distinct locations to access seasonal resources. We analyzed the sleep–wake patterns of 51 individuals as they resided in a village location (n = 39) and a forest camp (n = 23) (362 nights total). Overall, BaYaka exhibited high sleep fragmentation (50.5) and short total sleep time (5.94 h), suggestive of segmented sleep patterns. Sleep duration did not differ between locations, although poorer sleep quality was exhibited in the village. Linear mixed effect models demonstrated that women’s sleep differed significantly from men’s in the forest, with longer total sleep time (β ± SE =  − 0.22 ± 0.09, confidence interval (CI) = [− 0.4, − 0.03]), and higher sleep quality (efficiency; β ± SE =  − 0.24 ± 0.09, CI = [− 0.42, − 0.05]). These findings may be due to gender-specific social and economic activities. Circadian rhythms were consistent between locations, with women exhibiting stronger circadian stability. We highlight the importance of considering intra-cultural variation in sleep–wake patterns when taking sleep research into the field.

Objective To quantify the degree of change in cervical length (CL) over a 3-minute transvaginal ultrasound. Study Design We conducted a prospective observational study of nulliparous patients who underwent routine transvaginal CL screening at the time of their second-trimester ultrasound. We recorded CL at four time points (0, 1, 2, 3 minutes) and compared these values to determine the minute-to-minute change within a single patient. Results A total of 771 patients were included. The mean gestational age was 20.8 weeks (±0.84). We used a linear mixed effect model to assess if each minute during the ultrasound is associated with a change in CL. The intraclass correlation coefficient between minute 0 to minute 3 was 0.82 (95% confidence interval: 0.80, 0.84). This indicates that there is a relatively high within-patient correlation in CL during their ultrasound. Additionally, we stratified patients based on their starting CL; the intraclass correlation coefficient remained high for all groups. We additionally compared CL at each minute. Although there is a statistically significant difference between several time points, the actual difference is small and not clinically meaningful. Conclusion The variation in CL over a 3-minute transvaginal ultrasound examination is not clinically significant. It may be reasonable to conduct this examination over a shorter period.

The purpose of this study was to compare the effect of ear protectors on the sleep of preterm newborns during the “quiet” times in intermediate care nursery. This was a clinical, randomized, controlled crossover study conducted in two neonatal units in São Paulo, Brazil. The sample consisted of preterm infants who met the inclusion and exclusion criteria for the study. Polysomnography and unstructured observation were used for data collection. Twenty-four preterm infants with a mean gestational age of 33.2 weeks and current weight of 1.747 g were analyzed. There was no significant difference in the total sleep time of preterm infants with and without the use of ear protectors. Newborns with lower gestational age showed a significant reduction in total sleep time with the use of ear protectors ( p < .05). The use of ear protection did not increase the total sleep time for preterm infants.
