Effect of probiotic administration in adult atopic dermatitis patients

Introduction: Atopic dermatitis (AD) is a chronic skin disease characterized by abnormal skin barrier function and heightened immunologic sensitization. Its incidence has surged recently, with approximately 60% of cases diagnosed within the first year of life. AD can persist or recur, significantly deteriorating the quality of life due to persistent itching and sleep disturbances. Individuals with AD are at increased risk of developing other atopic disorders like asthma and allergic rhinitis. Various dietary approaches, including low carbohydrate, calorie, and fat diets, have been associated with enhanced quality of life by regulating immune responses. Probiotics have been used as adjuvant therapy in allergic conditions, though their effectiveness varies due to the complex nature of allergies. Method: A literature search was conducted using PubMed, Cochrane Library, and Google Scholar. MeSH terms, advanced search strategies, and predefined eligibility criteria were employed to identify relevant studies. Duplicate studies were excluded, and critical assessment tools and levels of evidence were defined per Oxford Center for Evidence-based Medicine standards. Results: One systematic review and meta-analysis of randomized controlled trials (RCTs) met the PICO and eligibility criteria. The meta-analysis demonstrated that probiotics significantly decreased AD severity in adults, enhancing their overall quality of life. Other meta-analyses and systematic reviews supported that probiotics reduce clinical severity and improve life quality in adult AD patients. Conclusion: Probiotic supplementation is a viable option to improve the quality of life for adult AD patients, offering potential therapeutic benefits in managing this condition.

Axonal injury, sleep disturbances, and memory following traumatic brain injury.

Traumatic brain injury (TBI) is associated with sleep deficits, but it is not clear why some report sleep disturbances and others do not. The objective of this study was to assess the associations between axonal injury, sleep, and memory in chronic and acute TBI. Data were acquired from two independent datasets which included 156 older adult veterans (69.8 years) from the Alzheimer's Disease Neuroimaging Initiative (ADNI) with prior moderate-to-severe TBIs and 90 (69.2 years) controls and 374 (39.6 years) from Transforming Research and Clinical Knowledge in TBI (TRACK-TBI) with a recent mild TBI (mTBI) and 87 controls (39.6 years), all who completed an MRI, memory assessment, and sleep questionnaire. Older adults with a prior TBI had a significant association between axonal injury and sleep disturbances [β = 9.52, 95% CI (4.1, 14.9), p = 0.01]. Axonal injury predicted changes in memory over 1-year in TBI [β = -8.72, 95% CI (-18, -2.7), p = 0.03]. We externally validated those findings in TRACK-TBI where axonal injury within 2 weeks after mTBI was significantly associated with higher sleep disturbances in the TBI group at 2 weeks[β = -7.2, 95% CI (-14, -0.50), p = 0.04], 6 months [β = -16, 95% CI (-24, -7.6), p ≤ 0.01], and 12 months post-injury [β = -11, 95% CI (-19, -0.85), p = 0.03]. These associations were not significant in controls. Axonal injury, specifically to the left anterior internal capsule is robustly associated with sleep disturbances in multiple TBI populations. Early assessment of axonal injury following mTBI could identify those at risk for persistent sleep disturbances following injury.

Sleep Disturbance in Children with Fetal Alcohol Spectrum Disorder and the Relationship to the Neurodevelopmental Profile.

Sleep disturbance is an important feature of fetal alcohol spectrum disorder (FASD). We sought to describe sleep patterns in school-aged children with FASD, in comparison with a typically developing community group, and investigate the relationship between sleep and neurodevelopmental profiles. The FASD cohort (N = 36) was recruited from a tertiary Australian FASD diagnostic center, and the typically developing group (N = 36) was previously recruited as a control cohort for a separate study. Sleep disturbance was assessed with the caregiver-completed Sleep Disturbance Scale for Children (SDSC) questionnaire. Neurodevelopmental assessment results for the 10 domains impaired in FASD were used for correlations with sleep disturbance. In the FASD group, 80% of children scored above the SDSC cutoff, compared with 22% of the control group ( p < 0.001). Statistically significant group differences were seen for all 6 subscales of the SDSC ( p < 0.05). The most frequently affected domains in the FASD group related to difficulties with initiating and maintaining sleep (58%), sleep-wake transition disorders (44%), and disorders of arousal (42%). A statistically significant relationship was not found between sleep and the severity of neurodevelopmental impairment or impairment of a particular domain, acknowledging the limitations of our small sample size. Half of the FASD sample (52%) were taking a pharmaceutical agent to support sleep, which was not associated with lower SDSC scores. In this small study, sleep disturbances were frequently reported by carers of children with FASD, independent of the severity of their neurodevelopmental impairments. Persistent sleep disturbance despite the use of sleep medications highlights the need for prospective studies exploring sleep interventions in this population. Integration of behavioral sleep medicine into management is recommended for all children with FASD.

Management of Fibromyalgia: An Update.

Fibromyalgia, a chronic pain condition marked by abnormal pain processing, impacts a significant part of the population, leading to reduced quality of life and function. Hallmark symptoms include widespread persistent pain, sleep disturbances, fatigue, cognitive dysfunction, and mood changes. Through this updated review, we aim to contribute to the evolving understanding and management of fibromyalgia, offering insights into the diverse tools available to improve the lives of those affected by this challenging condition. Management begins with educating patients to ultimately relieve them of unnecessary testing and provide reassurance. Treatment emphasizes a comprehensive approach, combining nonpharmacological interventions such as aforementioned education, exercise, and psychotherapy, alongside pharmacologic management-namely duloxetine, milnacipran, pregabalin, and amitriptyline-which have consistent benefits for a range of symptoms across the spectrum of fibromyalgia. Notably, drugs like nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen are generally not recommended due to limited efficacy and associated risks. Lastly, a variety of other medications have shown promise, including NMDA-receptor antagonists, naltrexone, and cannabinoids; however, they should be used with caution due to a small amount of evidence and potential for adverse effects.

Prevalences and Interrelationships of Post COVID-19 Fatigue, Sleep Disturbances, and Depression in Healthy Young and Middle-Aged Adults.

Background: An evaluation of the persistence of symptoms following COVID-19 in economically active young and middle-aged adults is crucial due to its significant socioeconomic impact resulting from compromised work performance. Methods: A prospective, multicenter study at 12 South Korean hospitals from January to December 2022 involved telephone interviews along with validated questionnaires. Results: Among 696 participants with a median age of 32 and no prior diagnoses, 30% of participants experienced persistent fatigue, while 21.4% suffered from sleep disturbance at 6 months following infection. Additionally, approximately 25% of the participants exhibited depression that endured for up to 6 months. Symptomatic individuals at 3 months exhibited a significantly higher prevalence of persistent fatigue, sleep disturbances, and depression at 6 months compared to those who remained asymptomatic. Notably, sleep disturbance and persistent fatigue at 3 months emerged as significant independent predictors of the presence of depression at 6 months. Conclusions: Even among young and middle-aged healthy adults, prolonged fatigue, sleep disturbance, and depression exhibit a significant prevalence and persisted for up to 6 months. Therefore, implementing a workplace management protocol for these symptoms is essential to mitigate the socioeconomic burden caused by the impairment of work efficiency.

3 Intensive Clinical Treatment and Rehabilitation for Veterans with Traumatic Brain Injury and Psychological Health Problems

Objective:Some active-duty military service members and veterans experience combinations of persistent traumatic stress, depression, suicidal ideation, anger, aggressive behavior, substance misuse, sleep disturbance, complicated grief, moral injury, headaches and migraines, chronic bodily pain, and cognitive weakness or deficits. The purpose of this study is to describe the clinical outcomes of active-duty service members and veterans who have completed the traumatic brain injury (TBI) and brain health track of a two-week intensive clinical treatment and rehabilitation program.Participants and Methods:The sample included 141 participants, with a history of TBI, in the Intensive Clinical Program (ICP). The ICP is a multidisciplinary, two-week treatment and rehabilitation program for active duty service members and veterans with complex psychological, cognitive, and physical health concerns. The program is comprised of daily individual therapy, group psychotherapy, psychoeducation, skills-building groups, and complementary and alternative medicine treatments. Participants in the ICP completed the following measures prior to initiating treatment and immediately following completion of treatment: Neurobehavioral Symptom Inventory (NSI), Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), Patient Health Questionnaire-9 (PHQ-9), Self-Efficacy for Symptom Management Scale (SE-SMS), and Patient-Reported Outcomes Measurement Information System (PROMIS)-Satisfaction with Participation in Social Roles and Activities-Short Form 8a, version 1.0 (PROMIS-S). Wilcoxon signed ranks tests were used to examine differences in scores on self-report measures from pretreatment to posttreatment for the full sample and within three subgroups stratified by age (in years: 20-34; 35-45; and 46-66). For the NSI, changes in the proportion of participants endorsing moderate or worse levels of individual symptoms from pretreatment to posttreatment were assessed using McNemar’s tests. Alpha levels were set at p&lt;0.05 for all analyses.Results:Participants reported statistically significant improvements across all of the administered measures (NSI, PCL-5, PHQ-9, PROMIS-S, and SE-SMS) upon conclusion of treatment. Effect sizes ranged from medium to large (d=0.34-1.04) for the full sample. Effect sizes were largely consistent across age subgroups (20-34: d=0.32-1.05; 35-45: d=0.55-0.96; 46-66: d=0.28-1.05). The magnitude of change on the SE-SMS appeared to be less with increasing age (20-34: d=1.05; 35-45: d=0.69; 46-66: d=0.28). Individual item analyses for the NSI revealed statistically significant reductions in the proportion of participants endorsing moderate or greater severity from pretreatment to posttreatment for 18 of 22 symptoms.Conclusions:Active duty service members and veterans participating in the two-week TBI and brain health intensive clinical program reported considerable symptom reduction at the conclusion of the program. Further research is indicated to assess the durability of symptom reduction.

Changes in sleep disturbance among Chinese adolescents: A population-based online survey

ObjectiveSleep disturbance is prevalent among adolescents but little is known about the short-term changes among Chinese adolescents. The study aimed to explore the prevalence and change patterns of sleep disturbance and identify its risk and protective factors. MethodsData were collected online from April 21st to May 12th, 2021 (Time 1, T1) and December 17th to 26th, 2021 (Time 2, T2). The final sample comprised 34,260 adolescents. Self-administrated questionnaires were used to assess socio-demographic variables, sleep disturbance, depression, anxiety, life events, family function, and resilience. ResultsThe prevalence of sleep disturbance was 12.0% at T1 and 11.8% at T2, with higher rates in females than males. Four groups of sleep disturbance change patterns were identified: non-sleep disturbance group (80.4%), persistent group (4.2%), new-onset group (7.6%), and remission group (7.8%). Risk factors for new-onset sleep disturbance included being in junior high school (AOR = 1.26, 95%CI = 1.15–1.38), family history of mental disorders (AOR = 1.49, 95%CI = 1.03–2.15), and moderate (AOR = 1.24, 95%CI = 1.13–1.36) and severe (AOR = 1.48, 95%CI = 1.27–1.72) family dysfunction. Risk factors for persistent sleep disturbance included being in junior (AOR = 1.25, 95%CI = 1.08–1.45) and senior (AOR = 1.53, 95%CI = 1.15–2.03) high school, parental currently unmarried status (AOR = 1.34, 95%CI = 1.05–1.73), moderate (AOR = 1.19, 95%CI = 1.02–1.39) and severe (AOR = 1.28, 95%CI = 1.06–1.55) family dysfunction. Medium (AOR = 0.48, 95%CI = 0.43–0.53) and high (AOR = 0.34, 95%CI = 0.29–0.40) levels of resilience were protective factors against new-onset sleep disturbance, as well as against persistent sleep disturbance (medium level: AOR = 0.51, 95%CI = 0.43–0.60; high level: AOR = 0.32, 95%CI = 0.25–0.43). ConclusionsInterventions aimed at promoting family functions and enhancing resilience may improve sleep disturbance among adolescents.

Exercise, Spinal Microglia and Neuropathic Pain: Potential Molecular Mechanisms.

As one of the most common neuropathic disorders, neuropathic pain often has a negative impact on patients with persistent pain, mood disorders and sleep disturbances. Currently, neuropathic pain is not treated with any specific drug, instead, drugs for other diseases are used as replacements in clinics, but most have adverse effects. In recent years, the role of spinal cord microglia in the pathogenesis of neuropathic pain has been widely recognized, and they are being explored as potential therapeutic targets. Spinal microglia are known to be involved in the pathogenic mechanisms of neuropathic pain through purine signaling, fractalkine signaling, and p38 MAPK signaling. Exercise is a safe and effective treatment, and numerous studies have demonstrated its effectiveness in improving neurological symptoms. Nevertheless, it remains unclear what the exact molecular mechanism is. This review summarized the specific molecular mechanisms of exercise in alleviating neuropathic pain by mediating the activity of spinal microglia and maintaining the phenotypic homeostasis of spinal microglia through purine signaling, fractalkine signaling and p38 MAPK signaling. In addition, it has been proposed that different intensities and types of exercise affect the regulation of the above-mentioned signaling pathways differently, providing a theoretical basis for the improvement of neuropathic pain through exercise.

Resolution of Sleep Disturbance and Improved Functional Outcomes After Rotator Cuff Repair

Background: Most patients experience sleep disturbances before rotator cuff repair, with these symptoms largely improving postoperatively. However, the relationship between the resolution or persistence of sleep disturbance and patient-reported outcomes after rotator cuff repair remains unknown. Purpose: To compare outcomes after rotator cuff repair between patients who reported a preoperative sleep disturbance and those who did not. Outcomes at various time points after surgery were also assessed in relation to the persistence or resolution of sleep disturbance. Study Design: Case-control study; Level of evidence, 3. Methods: Patients undergoing primary arthroscopic rotator cuff repair at a tertiary academic center were prospectively enrolled in a registry database. Patient characteristics were obtained preoperatively and validated patient-reported outcome measures (PROMs) were obtained pre- and postoperatively, including the visual analog scale for pain, American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation, Simple Shoulder Test, and Veterans RAND 12-Item Health Survey Physical and Mental components. Sleep disturbance was evaluated via responses to Simple Shoulder Test question 2. Patients with and without sleep disturbance were compared before and after surgery. Results: In total, 293 patients were prospectively enrolled. A total of 262 (89.8%) patients reported a sleep disturbance preoperatively. Of these, 221 (84.4%) reported a resolution of sleep disturbance by 2 years postoperatively. After adjustment for age, workers’ compensation status, and Cofield tear size, patients with a preoperative sleep disturbance reported significantly worse baseline PROMs, apart from the Veterans RAND 12-Item Health Survey Mental component, before surgery. However, postoperatively, these patients had greater improvement in PROMs, and no significant remaining differences were seen at follow-up between patients with and without preoperative sleep disturbance. Among patients who reported a preoperative sleep disturbance, those whose symptoms resolved postoperatively had superior PROM scores as well as significantly greater improvements from preoperative baseline values compared with patients with persistent sleep disturbances after surgery. Conclusion: Patients with preoperative sleep disturbances reported worse baseline functional scores before rotator cuff repair compared with patients without sleep disturbance. These disturbances largely resolved after surgery, with postoperative outcomes comparable with those of patients who reported no preoperative sleep concerns. Patients whose sleep disturbances resolved postoperatively also reported superior PROM scores compared with patients whose sleep disturbances persisted postoperatively.

Workplace Psychosocial Resources and Risk of Sleep Disturbances Among Employees

Workplace psychosocial resources naturally tend to cluster in some work teams. To inform work-related sleep health promotion interventions, it is important to determine the associations between clustering of workplace resources and sleep disturbances when some resources are high while others are low and to mimic an actual intervention using observational data. To examine whether clustering of and changes in workplace psychosocial resources are associated with sleep disturbances among workers. This population-based cohort study used data from the Swedish Longitudinal Occupational Survey of Health (2012-2018), the Work Environment and Health in Denmark study (2012-2018), and the Finnish Public Sector Study (2008-2014), collected biennially. Statistical analysis was conducted from November 2020 to June 2022. Questionnaires were distributed measuring leadership quality and procedural justice (ie, vertical resources) as well as collaboration culture and coworker support (ie, horizontal resources). Resources were divided into clusters of general low, intermediate vertical and low horizontal, low vertical and high horizontal, intermediate vertical and high horizontal, and general high. Odds ratios (ORs) and 95% CIs were reported from logistic regression models for the associations between the clustering of resources and concurrent and long-term sleep disturbances. Sleep disturbances were measured by self-administered questionnaires. The study identified 114 971 participants with 219 982 participant-observations (151 021 [69%] women; mean [SD] age, 48 [10] years). Compared with participants with general low resources, other groups showed a lower prevalence of sleep disturbances, with the lowest observed in the general high group concurrently (OR, 0.38; 95% CI, 0.37-0.40) and longitudinally after 6 years (OR, 0.52; 95% CI, 0.48-0.57). Approximately half of the participants (27 167 participants [53%]) experienced changes in resource clusters within 2 years. Improvements in vertical or horizontal dimensions were associated with reduced odds of persistent sleep disturbances, and the lowest odds of sleep disturbances was found in the group with improvements in both vertical and horizontal dimensions (OR, 0.53; 95% CI, 0.46-0.62). A corresponding dose-response association with sleep disturbances was observed for decline in resources (eg, decline in both dimensions: OR, 1.74; 95% CI, 1.54-1.97). In this cohort study of workplace psychosocial resources and sleep disturbances, clustering of favorable resources was associated with a lower risk of sleep disturbances.

Cannabidiol as a candidate pharmacotherapy for sleep disturbance in alcohol use disorder.

Among individuals with alcohol use disorder (AUD), it is estimated that the majority suffer from persistent sleep disturbances for which few candidate medications are available. Our aim wass to critically review the potential for cannabidiol (CBD) as a treatment for AUD-induced sleep disturbance. As context, notable side effects and abuse liability for existing medications for AUD-induced sleep disturbance reduce their clinical utility. CBD modulation of the endocannabinoid system and favorable safety profile have generated substantial interest in its potential therapeutic use for various medical conditions. A number of preclinical and clinical studies suggest promise for CBD in restoring the normal sleep-wake cycle and in enhancing sleep quality in patients diagnosed with AUD. Based on its pharmacology and the existing literature, albeit primarily preclinical and indirect, CBD is a credible candidate to address alcohol-induced sleep disturbance. Well-designed RCTs will be necessary to test its potential in managing this challenging feature of AUD.

Trajectories of sleep disturbance in cancer survivors during the first 2 years post-treatment.

To examine the trajectories of sleep disturbance in cancer survivors during the first 2 years post-treatment and to investigate whether psychological, cognitive, and physical factors differentiate trajectories. A total of 623 Chinese cancer survivors of diverse cancer types participated in a 2-year-long prospective study after the completion of cancer treatment. Sleep disturbance was measured using Pittsburgh Sleep Quality Index at 3 (T2), 6 (T3), 12 (T4), 18 (T5), and 24 (T6) months after baseline (within 6-months post-treatment; T1). Latent growth mixture modeling identified distinctive sleep disturbance trajectories and tested if these longitudinal patterns were predicted by baseline psychological distress, attentional control, attentional bias and physical symptom distress and T2 cancer-related distress. Fully adjusted multinomial logistic regression then identified whether these factors differentiated trajectories. Two distinct sleep disturbance trajectories were identified, namely stable good sleepers (69.7%) and persistent high sleep disturbance (30.3%). Compared to those in the stable good sleep group, patients in the persistent high sleep disturbance group were less likely to report avoidant (OR=0.49, 95% CI = 0.26-0.90), while more likely to report intrusive thoughts (OR = 1.76, 95% CI = 1.06-2.92) and cancer-related hyperarousal (OR = 3.37, 95% CI = 1.78-6.38). Higher depression scores also predicted persistent high sleep disturbance group membership (OR = 1.13, 95% CI = 1.03-1.25). Attentional bias, attentional control, anxiety, and physical symptom distress did not predict sleep trajectory membership. One in three cancer survivors experienced persistent high sleep disturbance. Screening and managing depressive symptoms and cancer-related distress in early cancer rehabilitation may reduce risk of persistent sleep disturbance among cancer survivors.

Practical Strategies for Longitudinal in-Home Sleep Tracking in Diverse Populations

Longitudinal monitoring of sleep metrics, night-to-night sleep quality, and weekly sleep patterns is important for enabling healthy aging and, more importantly, understanding and mitigating cognitive decline with aging. Recent work has shown that longitudinal changes in selected sleep metrics, such as total sleep time, time in the rapid eye movement (REM) versus non-REM sleep phases, and non-REM slow wave activity, is closely correlated with decline in cognitive function in older populations. Further, evidence also suggests that sleep disturbance in middle-aged and older populations can contribute to cognitive decline and heighten the risk of Alzheimer's Disease (AD) by increasing beta-amyloid burden. In older, at-risk populations, persistent sleep disturbances and/or shifts in sleep patterns also precede an AD diagnosis and may even appear years before cognitive decline, indicating that clinically-accurate, longitudinal sleep tracking can allow for on-time therapeutics and interventions before onset of AD symptoms.However, clinical-grade wearable sleep monitoring is a challenging problem since it requires simultaneous monitoring of brain activity, eye movement, muscle activity, cardio-respiratory features, and gross body movements. This requires multiple sensors to be worn at different locations as well as uncomfortable adhesives and discrete electronic components to be placed on the head. As a result, existing wearables either compromise comfort or compromise accuracy in tracking sleep variables.I will describe our lab's recent work in developing a suite of fabric-based sensors and garment-integrated sensing systems for in-home sleep tracking, focusing particularly on our efforts at enabling clinically-accurate sleep phase recognition. Our best-performing solution is PhyMask, an all-textile sleep monitoring solution that is practical and comfortable for continuous use and that acquires all signals of interest to sleep solely using comfortable textile sensors placed on the head. We show that PhyMask can be used to accurately measure all the signals required for precise sleep stage tracking and to extract advanced sleep markers such as spindles and K-complexes robustly in the real-world setting. We validate PhyMask against polysomnography and show that it significantly outperforms other commercially-available sleep tracking wearables, including the Fitbit wristband, the Oura Ring, and the Muse, Phillips SmartSleep and Dreem headbands.

Anxiety sensitivity as a transdiagnostic risk factor for trajectories of adverse posttraumatic neuropsychiatric sequelae in the AURORA study

Anxiety sensitivity, or fear of anxious arousal, is cross-sectionally associated with a wide array of adverse posttraumatic neuropsychiatric sequelae, including symptoms of posttraumatic stress disorder, depression, anxiety, sleep disturbance, pain, and somatization. The current study utilizes a large-scale, multi-site, prospective study of trauma survivors presenting to emergency departments. Hypotheses tested whether elevated anxiety sensitivity in the immediate posttrauma period is associated with more severe and persistent trajectories of common adverse posttraumatic neuropsychiatric sequelae in the eight weeks posttrauma. Participants from the AURORA study (n = 2,269 recruited from 23 emergency departments) completed self-report assessments over eight weeks posttrauma. Associations between heightened anxiety sensitivity and more severe and/or persistent trajectories of trauma-related symptoms identified by growth mixture modeling were analyzed. Anxiety sensitivity assessed two weeks posttrauma was associated with severe and/or persistent posttraumatic stress, depression, anxiety, sleep disturbance, pain, and somatic symptoms in the eight weeks posttrauma. Effect sizes were in the small to medium range in multivariate models accounting for various demographic, trauma-related, pre-trauma mental health-related, and personality-related factors. Anxiety sensitivity may be a useful transdiagnostic risk factor in the immediate posttraumatic period identifying individuals at risk for the development of adverse posttraumatic neuropsychiatric sequelae. Further, considering anxiety sensitivity is malleable via brief intervention, it could be a useful secondary prevention target. Future research should continue to evaluate associations between anxiety sensitivity and trauma-related pathology.

Monocentric retrospective clinical outcome in a group of 13 patients with opsoclonus myoclonus syndrome, proposal of diagnostic algorithm and review of the literature.

Dancing eye syndrome or opsoclonus-myoclonus syndrome (OMS) is a very rare disease (incidence <1/5,000,000 per year), which is more prevalent in young children. Although it is not usually a cause of mortality, the aftermaths are not rare. We performed an observational retrospective review of children diagnosed with OMS in our neuropediatric department from 1996 to 2020, with the objective of assessing the prognostic value of initial clinical features. All medical data from diagnosis to last follow-up were reviewed. We defined unfavorable evolution of OMS as persistence or worsening of symptoms. Subsequently, based on a literature review, our results and experience, a diagnostic algorithm was developed. A total of 13 OMS patients were included: 61.5% were male (n=8), median age at diagnosis was 18 months (IR=76), median treatment delay was 14 days (IR=146) and OMS score at onset was 8 (IR=11). The most frequent etiologies were neuroblastoma-associated and idiopathic OMS (38.46%; n=5) of the patients, followed by post-infectious OMS (n=3). All the patients were treated with corticosteroids, five required a surgical intervention (neuroblastoma group), and three required adjunctive immune therapy (immunoglobulins, cyclophosphamide and/or rituximab). We detected neurodevelopmental disorders in 38.46% (n=5) of the patients, mainly attention deficit (n=4), and persistent sleep disturbances (n=4). The median OMS score at the end of follow-up was 1 (IR=3). An important diagnostic delay, OMS score of ≥10 and age >1 year at onset may correlate with a higher risk of aftermaths. We detected a better prognosis in the post-infectious OMS, with full recovery occurring in 2/3 of patients. Early clinical suspicion is key to guarantee maximum response of treatment.

Quetiapine Add-On Therapy May Improve Persistent Sleep Disturbances in Patients with PTSD on Stabile Combined SSRI and Benzodiazepine Combination: A One-Group Pretest-Posttest Study.

To assess potential benefits of quetiapine for persistent sleep disturbances in patients with posttraumatic stress disorder (PTSD) on stable combined SSRI and benzodiazepine therapy, who previously failed to respond to various benzodiazepine and non-benzodiazepine hypnotic adjuvant treatment as well as to first-generation antipsychotic add-on treatment. Fifty-two male PTSD outpatients on stable combination treatment with SSRI and benzodiazepines, with persistent sleep disturbances not responding to prescription of zolpidem, flurazepam, nitrazepam, promazine, and levopromazine, were assessed for sleep disturbances improvements after prescription of quetiapine in the evening. Each patient met both ICD-10 and DSM-IV criteria for PTSD. Psychiatric comorbidity and premorbidity were excluded using the Mini-International Neuropsychiatric Interview (MINI). Improvement on the CAPS recurrent distressing dream item, reduction in the amount of time needed to fall asleep, prolongation of sleep duration, and reduction in average number of arousals per night in the last 7 days before the assessment period were used as efficacy measures. All sleep-related parameters improved significantly at the end of a five-week follow-up: sleep duration increased by one hour (p<0.001), sleep latency decreased by 52.5 minutes (p<0.001), median number of arousals per night decreased from two to one (p<0.001), CAPS recurrent distressing dream item median decreased from five to four (p<0.001), and the number of patients dissatisfied with their sleep quality and quantity decreased from 45 to two (p<0.001). Quetiapine prescribed in the evening may be successful therapy for persistent sleep disturbances in patients with PTSD and generally good response to an SSRI and benzodiazepine combination, who previously failed to respond to some of the usual hypnotic medication or addition of first-generation antipsychotics: zolpidem, flurazepam, nitrazepam, promazine, and levopromazine.

Sleep disturbance after acute coronary syndrome: A longitudinal study over 12 months.

Sleep disturbance has been associated with poor prognosis in patients with acute coronary syndrome (ACS). This study examined the course of sleep disturbance and associated factors in patients with ACS who were followed for one year. Study participants were 180 patients (mean age 59.6 years, 81.7% men) with ACS admitted to a tertiary hospital to undergo acute coronary intervention. Sleep disturbance was interviewer-assessed at admission (n = 180), at 3 months (n = 146), and at 12 months (n = 101) using the Jenkins Sleep Scale (JSS)-4, with a total of 414 assessments over one year. Random linear mixed regression models were used to evaluate the relationship between sociodemographic factors, cardiac diseases severity, perceived distress during ACS, comorbidities, medication, health behaviors, and sleep disturbance over time. At admission, 3 months, and 12 months, 56.7%, 49.3%, and 49.5% of patients, respectively, scored above the mean value for sleep disturbance in the general population (JSS-4 score ≥5). There was a significant decrease in continuous JSS-4 scores over time [estimate (SE) = -0.211 (0.074), p = 0.005]. Female sex [0.526 (0.206), p = 0.012], greater fear of dying [0.074 (0.026), p = 0.004], helplessness during ACS [0.062 (0.029), p = 0.034], and a history of depression [0.422 (0.171), p = 0.015] were independently associated with higher JSS-4 scores over time. Despite a decrease from admission to 3 months, sleep disturbance is prevalent in the first year after ACS. Female sex, depression history, and distress during ACS identify patients at increased risk of developing persistent sleep disturbance and may inform interventions to prevent sleep disturbance.

Worsening sleep quality across the lifespan and persistent sleep disturbances in persons with opioid use disorder.

Individuals with opioid use disorder (OUD) may experience worsening sleep quality over time, and a subset of individuals may have sleep disturbances that precede opioid use and do not resolve following abstinence. The purpose of the present study was to (1) collect retrospective reports of sleep across the lifespan and (2) identify characteristics associated with persistent sleep disturbance and changes in sleep quality in persons with OUD. Adults with OUD (n = 154) completed a cross-sectional study assessing current and past sleep disturbance, opioid use history, and chronic pain. Repeated-measures analysis of variance was used to examine changes in retrospectively reported sleep quality, and whether changes varied by screening positive for insomnia and/or chronic pain. Multivariate linear regression analyses were used to identify additional correlates of persistent sleep disturbance. Participants reported that their sleep quality declined over their lifespan. Changes in reported sleep over time varied based on whether the individual screened positive for co-occurring insomnia and/or chronic pain. In regression analyses, female sex (β = 0.16, P = .042), a greater number of treatment episodes (β = 0.20, P = .024), and positive screens for chronic pain (β = 0.19, P = .018) and insomnia (β=0.22, P = .013) were associated with self-reported persistent sleep disturbance. Only a portion of participants who screened positive for sleep disorders had received a formal diagnosis. OUD treatment providers should routinely screen for co-occurring sleep disturbance and chronic pain. Interventions that treat co-occurring OUD, sleep disturbance, and chronic pain are needed.

The risk of insomnia after surgical operation: A longitudinal, population-based, case-crossover study.

The acute onset of insomnia following surgical operations has long been neglected, and long-term outcomes are not clear. Our aims were (1) to evaluate the risk of postoperative insomnia, (2) to identify which surgeries are related, and (3) to follow patients with postoperative insomnia for the development of major mental and physical disorders. We conducted a case-crossover study comprising 9898 participants with new-onset insomnia from the Taiwan National Health Insurance Research Database between 1997 and 2011. We determined the odds of having surgery in the case period (30 days) before the onset of insomnia by logistic regression analysis. Types of surgery that postoperative insomniacs had undergone were compared with age-/gender-/timing-matched controls. Longitudinal follow-up of postoperative and non-postoperative insomniacs was performed. The odds ratio of surgical exposure vs. nonexposure within 30 days was 12.05 (p < 0.001) before new-onset insomnia. Surgery of musculoskeletal and nervous systems predisposed to insomnia. The duration of hypnotic drug use (0.83 years) was shorter and with a nearly 2-fold faster remission rate in postoperative than in non-postoperative insomniacs (1.45 years). Approximately 25% of each insomnia group developed persistent sleep disturbance. Surgery is associated with subsequent insomnia, which has a shorter duration and a faster remission than non-postoperative insomnia. Our data provide a reference for postoperative care, and warrant future studies.
