Abstract
Introduction/Objective
Hyaline arteriolosclerosis is a common feature of diabetic microangiopathy. It results from hyperglycemia-induced endothelial cell dysfunction and can be found in many sites including the retina, kidney, and skin. This histologic finding is important because studies have shown that in the kidney it is an independent risk factor for cardiovascular complications. To our knowledge, an association between hyperglycemia and hyaline arteriolosclerosis in the liver has not be studied. We aimed to investigate whether chronic hyperglycemia is associated with this histologic finding in liver arterioles.
Methods/Case Report
The first 50 liver biopsies performed at our institution starting January 1, 2020 were scanned into a digital pathology system (Philips, Cambridge, MA). For each biopsy, the patient’s highest recorded hemoglobin A1c (HbA1c) up to one year from the date of biopsy was recorded. The biopsies were then grouped into two groups: those from patients with a HbA1c greater than 6.5%, and those with a HbA1c value less than 6.5 %. Next, the digested periodic acid Schiff (DPAS) intensity of the arteriolar vessels in each biopsy was graded 0 to 3 by a single pathology resident who was blinded to its corresponding HbA1c group. Grade 0 to 1 was considered negative staining. Grade 2 to 3 was considered positive staining and indicative of hyaline arteriolosclerosis. By the end of the data collection, each case had been given a staining category and a HbA1c group. A 2 x 2 contingency table was constructed.
Results (if a Case Study enter NA)
37 of 50 patients had a recorded HbA1c meeting the study criteria. Of these 37 patients, 11 had an HbA1c greater than 6.5 % while 26 had an HbA1c less than 6.5%. Seven of the 11 biopsies from patients with an elevated HbA1c showed positive staining. Six of the 26 biopsies from patients with an HbA1c less than 6.5% showed positive staining.
Conclusion
We hypothesized that patients living with hyperglycemia may be more likely to exhibit hepatic hyaline arteriolosclerosis. A chi-squared test of independence was performed to examine the association between a liver biopsy’s HbA1c group and staining category. The relation between these variables was significant at p = < .05, χ 2 (2, N= 36) = 5.57, p = .0182, indicating liver biopsies with a HbA1c greater than 6.5 % are more likely to have this histologic finding. Future studies are needed to characterize diabetic hepatopathy, and its relatedness to macrovascular complications.

Abstract
BACKGROUND Systemic infections and chronic graft rejection represent common causes of mortality and morbidity in heart transplant patients. In severe cases, cardiogenic shock (CS) may occur and require hemodynamic stabilization with temporary mechanical circulatory support (tempMCS). Under these devastating circumstances, treatment of sequelae of left ventricular dysfunction, such as secondary mitral regurgitation (MR) is challenging, especially when surgical repair is deemed futile. In nontransplant patients, interventional mitral valve repair strategies such as the MitraClip system (Abbott Cardiovascular) have been used to successfully treat secondary MR and allow for weaning from tempMCS. CASE SUMMARY We report about the first patient in whom profound CS after heart transplantation was stabilized with tempMCS followed by interventional elimination of secondary MR.

Abstract
PURPOSE This study aimed to investigate potential bidirectional relations between key sleep characteristics and somatic symptoms with past 30-day marijuana use in high school students. METHODS Participants from the NEXT Generation Health Study (n = 2,770) reported on 10th and 11th grade (W1 and W2) sleep characteristics and somatic symptoms and 12th grade (W3) past 30-day marijuana. Multivariate logistic regressions and path analyses were conducted. RESULTS Sleep duration was not associated with marijuana use. However, later W1 chronotype, greater W1 social jetlag, W1 trouble falling asleep, W1 trouble staying asleep, and W1 somatic symptoms were associated with increased odds of W3 past 30-day marijuana use. Path models indicated direct associations between W1 chronotype and W3 past 30-day marijuana use, and W1 social jetlag and W3 past 30-day marijuana use. CONCLUSIONS Later sleep timing was longitudinally associated with past 30-day marijuana use. Improved understanding of sleep health, specifically chronotype and social jetlag as risk factors for marijuana use is warranted, which may inform additional screening targets and interventions that address these associated domains.

Abstract
OBJECTIVES The HeartWare HVAD (HW) and the HeartMate3 (HM3) are presently the most commonly used continuous-flow left ventricular assist devices worldwide. We compared the outcomes of patients supported with either of these 2 devices based on data from the EUROMACS (European Registry for Patients with Mechanical Circulatory Support). METHODS A retrospective analysis of the survival and complications profile in propensity score-matched adult patients enrolled in the EUROMACS between 01 January 2016 and 01 September 2020 and supported with either an HW or HM3. Matching included demographic parameters, severity of cardiogenic shock and risk-modifying end-organ parameters that impact long-term survival. Survival on device and major postoperative adverse events were analysed. RESULTS Following 1:1 propensity score matching, each group consisted of 361 patients. Patients were well balanced (<0.1 standardized mean difference). The median follow-up was similar in both groups [396 (interquartile range (IQR) 112-771) days for HW and 376 (IQR 100-816) days for HM3]. The 2-year survival was similar in both groups [HW: 61% 95% confidence interval (CI) (56-67%) vs HM3: 68% 95% CI (63-73%) (stratified hazard ratio for mortality: 1.13 95% CI (0.83-1.54), P = 0.435].The cumulative incidence for combined major adverse events and unexpected readmissions was similar in both groups [subdistribution hazard ratio (SHR) 1.0 (0.84-1.21), P = 0.96]. Patients in the HW group demonstrated a higher risk of device malfunction [SHR 2.44 (1.45-3.71), P < 0.001], neurological dysfunction [SHR 1.29 (1.02-1.61), P = 0.032] and intracranial bleeding [SHR 1.76 (1.13-2.70), P = 0.012]. CONCLUSIONS Mid-term survival in both groups was similar in a propensity-matched analysis. The risk of device malfunction, neurological dysfunction and intracranial bleeding was significantly higher in HW patients.

Abstract
BACKGROUND The aim of this study was to evaluate the impact of the surgical approach on the postoperative outcome in patients who underwent left ventricular assist device (LVAD) implantation after having received veno-arterial extracorporeal life support (va-ECLS) using data from a European registry (ECLS-VAD). Five hundred and thirty-one patients were included. METHODS A propensity score-adjusted outcome analysis was performed, resulting in 324 patients in the full sternotomy (FS) group and 39 in the less invasive surgery (LIS) group. RESULTS The surgery lasted in median 236 min in the FS group versus 263 min in the LIS group (p = 0.289). The median chest tube output during the first 24 h was similar in both groups. Patients who underwent implantation with an FS required more blood products during the first 24 postoperative hours (median 16 vs. 12, p = 0.033). The incidence of revision due to bleeding was also higher (35.5 vs. 15.4%, p = 0.016). A temporary postoperative right ventricular assist device was necessary in 45.1 (FS) versus 23.1% (LIS) of patients, respectively (p = 0.067). No stroke occurred in the LIS group during the first 30 days after surgery (7.4% in the FS group). The incidence of stroke and of renal, hepatic, and respiratory failure during the follow-up was similar in both groups. The 30-day and one-year survival were similar in both groups. CONCLUSION LIS for implantation of a durable LVAD in patients on va-ECLS implanted for cardiogenic shock is associated with less revision due to bleeding, less administration of blood products and absence of perioperative stroke, with no impact on survival.

Abstract
Background Breast cancer survivors (BCSs) are a growing population with a higher prevalence of insomnia than women of the same age without a history of cancer. Cognitive behavioral therapy for insomnia (CBT-I) has been shown to be effective in this population, but it is not widely available to those who need it. Objective This study aimed to better understand BCSs’ experiences with insomnia and to explore the feasibility and acceptability of delivering CBT-I using a virtual assistant (Amazon Alexa). Methods We first conducted a formative phase with 2 focus groups and 3 in-depth interviews to understand BCSs’ perceptions of insomnia as well as their interest in and comfort with using a virtual assistant to learn about CBT-I. We then developed a prototype incorporating participant preferences and CBT-I components and demonstrated it in group and individual settings to BCSs to evaluate acceptability, interest, perceived feasibility, educational potential, and usability of the prototype. We also collected open-ended feedback on the content and used frequencies to describe the quantitative data. Results We recruited 11 BCSs with insomnia in the formative phase and 14 BCSs in the prototype demonstration. In formative work, anxiety, fear, and hot flashes were identified as causes of insomnia. After prototype demonstration, nearly 79% (11/14) of participants reported an interest in and perceived feasibility of using the virtual assistant to record sleep patterns. Approximately two-thirds of the participants thought lifestyle modification (9/14, 64%) and sleep restriction (9/14, 64%) would be feasible and were interested in this feature of the program (10/14, 71% and 9/14, 64%, respectively). Relaxation exercises were rated as interesting and feasible using the virtual assistant by 71% (10/14) of the participants. Usability was rated as better than average, and all women reported that they would recommend the program to friends and family. Conclusions This virtual assistant prototype delivering CBT-I components by using a smart speaker was rated as feasible and acceptable, suggesting that this prototype should be fully developed and tested for efficacy in the BCS population. If efficacy is shown in this population, the prototype should also be adapted for other high-risk populations.

Abstract
STUDY OBJECTIVES Sexual minority adolescents experience mental and physical health disparities attributable to increased discrimination and minority stress. These same factors may also impair sleep health, although available literature on this topic is limited. This study examined longitudinal associations between adolescent sexual minority status and seven sleep behaviors in young adulthood and tested depressive symptoms and overweight as mediators. METHOD Data were drawn from Waves 2 (11th grade) to 7 (4 years after high school) of the NEXT Generation Health Study, a national longitudinal cohort study of US adolescents (n = 1946; 6.3% sexual minorities). RESULTS There were no significant sexual orientation disparities in sleep duration, trouble falling asleep, trouble staying asleep, or trouble waking up during young adulthood. Relative to heterosexual females, sexual minority females had higher odds of snoring/stop breathing (36.6% versus 19.2%; adjusted odds ratio = 2.57; 95% confidence interval = 1.30, 5.09) and reported more frequent daytime sleepiness (b = 0.66, 95% confidence interval = 0.05, 1.27). Mediation analyses revealed that female sexual minority status was associated with increased risk of snoring/stop breathing though overweight status (mediated 43.6% of total effect) and was also associated with increased daytime sleepiness through higher depressive symptoms (mediated 70.8% of total effect). CONCLUSIONS Among US youth, no sexual orientation disparities were found except for snoring/stop breathing and daytime sleepiness among females. Sexual orientation disparities in these aspects of sleep are partially due to worse mental and physical health among sexual minority females, highlighting depressive symptoms and overweight problems as potential intervention targets.

Abstract
Inadequate sleep and problematic drinking are prevalent among high school students and are significant public health issues. Inadequate sleep may contribute to alcohol use through impairments in emotion regulation or cognitive functioning, whereas alcohol use may lead to inadequate sleep through the biological effects of alcohol or social influences. However, the directionality of the associations between sleep and drinking variables remains unclear as most prior studies were cross-sectional. This study utilizes longitudinal data from the NEXT Generation Health Study to examine bidirectional associations between alcohol use and sleep adequacy in a nationally representative sample across 3 years of high school. Students reported usual bedtimes and waketimes for scheduled- and free-days, alcohol use, and heavy episodic drinking. Estimates of sleep duration, chronotype, and social jetlag were calculated. Cross-lagged autoregressive models revealed evidence of alcohol use predicting subsequent sleep duration and timing, and sleep timing predicting subsequent alcohol use. Specifically, previous-wave alcohol use predicted shorter free-day sleep duration and later chronotype at 11th and 12th grade, and more social jetlag at 12th grade; similar results were obtained for heavy episodic drinking. Eleventh grade social jetlag predicted subsequent year current alcohol use; eleventh grade chronotype and social jetlag predicted subsequent year heavy episodic drinking. Bidirectional findings suggest that alcohol use and sleep may reflect mutually reinforcing life style choices. Understanding these bidirectional associations could inform risk prevention interventions. Given the implications of poor sleep for adolescents, further research on possible social influences on the alcohol-sleep relations is merited. Clinical Trial Registration: NCT01031160.

Abstract
Study Objectives The relationship between sleeping and smoking during adolescence remains unclear and is likely complex. We aim to evaluate the longitudinal reciprocal associations between sleep problems, sleep duration, and smoking among non-Hispanic white (NHW) and non-Hispanic black (NHB) youth. Design Prospective cohort study. Setting NEXT Generation Health Study. Participants A national sample (N = 1394) of NHB and NHW 10th graders were surveyed annually between 2009 (Wave 1) and 2012 (Wave 3). Interventions N/A. Measurements and Results Past 30-day smoking, chronic difficulty falling asleep, recent difficulty falling asleep, difficulty staying asleep, and weekday and weekend sleep duration were measured at each wave. Using structural equation models, we observed significant autocorrelations over time for sleep problems and sleep duration. We found significant reciprocal, prospective relationships between smoking and sleep problems. The strengths of the relationships differed by race, with a stronger association between sleep problems and subsequent smoking for NHB than NHW youth. Conversely, a stronger association between smoking and subsequent sleep problems for NHW than NHB youth was observed. These association were independent of demographics, snoring or sleep apnea, body mass index, depressive symptoms, alcohol use, and soda consumption. Conclusions Reciprocal and prospective relationships exist for youth smoking and sleep problems and duration in both NHW and NHB youth. Further research is needed to unravel the complex relationship between the direct effects of nicotine, lifestyle choices that may link smoking and sleep problems, and racial differences.

Abstract
Study Objectives To examine the association between self-reported sleep duration (SD) and peer/individual factors predictive of risky behaviors (risk behavior factors) in a large socioeconomically diverse school-based sample of early adolescents. Design, Setting, and Participants Survey data collected from 10718 and 11240 eighth-grade students in 2010 and 2012, respectively, were analyzed. Intervention N/A. Measurements and Results Self-reported school night SD was grouped as ≤4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, and ≥10 hours. Scores on 10 peer/individual risk behavior factor scales were dichotomized according to national eigth-grade cut points. The percentage of students reporting an "optimal" SD of 9 hours was 14.8% and 15.6% in 2010 and 2012, respectively; 45.6% and 46.1% reported <7 hours. Adjusted for covariates of gender, race, and SES, multilevel logistic regression results showed that odds ratios (ORs) for 9 of 10 risk factor scales increased with SD <7 hours, with a dose-response effect for each hour less sleep compared to an SD of 9 hours. For example, ORs for students sleeping <7 hours ranged from 1.3 (early initiation of antisocial behavior) to 1.8 (early initiation of drug use). The risk factor scale ORs for <5 hours SD ranged from 3.0 (sensation seeking) to 6.4 (gang involvement). Conclusions Middle school students are at high risk of insufficient sleep; in particular, an SD <7 hours is associated with increased risk behavior factors.

Abstract
OBJECTIVE To determine whether shorter school-night sleep duration, greater daytime sleepiness, and greater eveningness chronotype were associated with lower self-regulation among adolescents. METHODS An online survey of 7th- to 12th-grade students in 19 schools in Fairfax County, Virginia Public Schools was conducted in 2015. Self-regulation was measured with the Behavior Rating Inventory of Executive Function, 2nd edition, Screening Self-Report Form. Sleep measures included school night-sleep duration (hours between usual bedtime and wake time), daytime sleepiness (Sleepiness Scale in the Sleep Habits Survey, tertiles), and chronotype (Morningness-Eveningness Scale for Children, continuous score and tertiles). Sociodemographic factors and mental health conditions were analyzed as potential confounders. RESULTS Among 2017 students surveyed, the mean age was 15.0 years (range, 12.1-18.9 years), and 21.7% slept <7 hours on school nights. In regression models adjusted for confounders, there was a significant independent association between self-regulation and both chronotype (P < .001) and daytime sleepiness (P < .001) but not sleep duration (P = .80). Compared with those in the lowest tertile of daytime sleepiness, those in the highest tertile had lower (0.59 SD units; 95% confidence interval, 0.48-0.71) self-regulation, as did those in the eveningness tertile of chronotype compared with those in the morningness tertile (0.35 SD units lower; 95% confidence interval, 0.24-0.46). CONCLUSIONS Among adolescents, greater daytime sleepiness and greater eveningness chronotype were independently associated with lower self-regulation, but shorter sleep duration was not. Aspects of sleep other than school-night sleep duration appear to be more strongly associated with self-regulation.

Pediatr Blood Cancer 2016; 63:880-6.

Abstract
BACKGROUND Adolescents with cancer experience many troubling symptoms, including sleep disruptions that can affect mood and quality of life. Massage is a safe and popular intervention that has demonstrated efficacy in pediatric and adult patients with cancer. This study aimed to assess the feasibility of conducting a massage intervention to help with sleep in hospitalized adolescent oncology patients. PROCEDURE Adolescents ages 12-21 with cancer who were expected to be hospitalized for at least four consecutive nights were recruited from the inpatient unit at Children's National Health System and randomized to either massage intervention or a waitlist control. Patients in the intervention group received one massage per night, for two or three nights. Sleep was measured with actigraphy and patient and proxy reported instruments were used to measure fatigue, mood, and anxiety. RESULTS The majority (78%) of patients approached for the study consented, and almost all patients in the intervention group (94%) received at least one massage, 69% received two, and rates of completion of instruments among adolescents were high demonstrating feasibility. There were trends toward increased night time and overall sleep in the intervention group compared with standard of care, but no differences between groups in the patient reported outcome measures. Participant and parent feedback on the intervention was positive and was the impetus for starting a clinical massage service at the hospital. CONCLUSIONS Massage for hospitalized adolescents with cancer is feasible, well received, and can potentially improve patients' sleep. A randomized multicenter efficacy study is warranted.

Abstract
BACKGROUND Physical activity as measured by activity counts over short time intervals across a 24 h period are often used to assess circadian variation. We are interested in characterizing circadian patterns in activity among adolescents and examining how these patterns vary by obesity status. New statistical approaches are needed to examine how factors affect different features of the circadian pattern and to make appropriate covariate adjustments when the outcomes are longitudinal count data. METHODS We develop a statistical model for longitudinal or repeated activity count data that is used to examine differences in the overall activity level, amplitude (defined as the difference between the lowest and highest activity level over a 24 hour period), and phase shift. Using seven days of continuous activity monitoring, we characterize the circadian patterns and compare them between obese and non-obese adolescent girls. RESULTS We find a statistically significant phase delay in adolescent girls who were obese compared with their non-obese counterparts. After the appropriate adjustment for measured potential confounders, we did not find differences in mean activity level between the two groups. CONCLUSION New statistical methodology was developed to identify a phase delay in obese compared with non-obese adolescents. This new approach for analyzing longitudinal circadian rhythm count data provides a useful statistical technique to add to the repertoire for those analyzing circadian rhythm data.

L-Dopa improves Restless Legs Syndrome and periodic limb movements in sleep but not Attention-Deficit-Hyperactivity Disorder in a double-blind trial in children. Sleep Med 2011; 12:471-7. [PMID: 21463967 PMCID: PMC3094572 DOI: 10.1016/j.sleep.2011.01.008] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2010] [Revised: 01/19/2011] [Accepted: 01/26/2011] [Indexed: 10/18/2022]
Abstract
BACKGROUND In a previous open-label study, dopaminergic agents improved Restless Legs Syndrome (RLS) and Periodic Limb Movements in Sleep (PLMS), as well as Attention-Deficit-Hyperactivity Disorder (ADHD) in children with both disorders. We therefore conducted a double-blind placebo-controlled trial of L-DOPA in ADHD children with and without RLS/PLMS. METHODS Two groups of patients (total n = 29), those with ADHD only or those with ADHD and RLS/PLMS, were randomized to L-DOPA or placebo therapy. At baseline and after therapy patients were assessed with Conners' parent and teacher rating scales; polysomnography; RLS rating scale; and neuropsychometric measures of memory, learning, attention, and vigilance. RESULTS L-DOPA improved RLS/PLMS symptoms in all patients with those disorders compared with placebo (p = .007). When assessed by the Conners' Scales before therapy, ADHD was more severe in children without RLS/PLMS than in children with RLS/PLMS (p = 0.006). L-DOPA had no effect on Conners' scales, sleep, or neuropsychometric tests when all patients treated with the drug were compared to those on placebo or when patients with ADHD only were compared to those with ADHD and RLS/PLMS. CONCLUSIONS In this first double-blind study of a dopaminergic therapy in children with RLS/PLMS, L-Dopa significantly improved RLS/PLMS but not ADHD. These results, however, should be interpreted carefully since they may have been influenced by the relatively small sample size and the baseline differences in severity of ADHD symptoms. Further work needs to be done to elucidate the relationship between dopamine, ADHD and RLS/PLMS.

Abstract
OBJECTIVES Patients with SSADH deficiency, a disorder of chronically elevated endogenous GABA and GHB, were studied for sleep symptoms and polysomnography. We hypothesized that patients would have excessive daytime somnolence and decreased REM sleep. DESIGN Polysomnography and MSLT were performed on patients enrolled for comprehensive clinical studies of SSADH deficiency. SETTING Sleep studies were obtained in the sleep laboratories at CNMC and NIH. PATIENTS Sleep recordings were obtained in 10 patients with confirmed SSADH deficiency. INTERVENTIONS Thirteen overnight polysomnograms were obtained in 10 patients (7 male, 3 female, ages 11-27 y). Eleven MSLT studies were completed in 8 patients. MEASUREMENTS AND RESULTS Polysomnograms showed prolongation of REM stage latency (mean 272 +/- 89 min) and decreased percent stage REM (mean 8.9%, range 0.3% to 13.8%). Decreased mean sleep latency was present in 6 of 11 MSLTs. CONCLUSIONS SSADH deficiency is associated with prolonged latency to stage REM and decreased percent stage REM. This disorder represents a model of chronic GABA and GHB accumulation associated with suppression of REM sleep.
