The article presents case study of a 50-year-old man who underwent endoscopic salvage of a duodenal stump leak and surgical transection of the ampulla. It mentions information on observation of extensive progression of the tumor upon computed tomography (CT) scan. It states that internal biliary drainage was achieved by endoscopic ultrasonography (EUS)-guided choledochoduodenostomy using a lumen-apposing stent.

Adolescence and young adulthood are transitional periods associated with significant changes and challenges, leading to a heightened vulnerability to sleep disturbances and mental health difficulties. This stage is often associated with an increased preference for eveningness, manifested as a later chronotype. The current study aimed to investigate the directionality of the association between chronotype, based on an individual's sleep-wake behaviour, and insomnia in young people using a two-wave panel design with a 12-month interval. A total of 370 participants aged 15-24 (mean age: 21.0 ± 2.0, 72.7% female) were recruited from local secondary schools and universities. Insomnia symptoms were assessed using the Insomnia Severity Index, while chronotype was measured using the Munich Chronotype Questionnaire. Temporal associations were analysed using a series of cross-lagged panel models. The best fitting and most parsimonious model indicated that a later chronotype at baseline predicts more severe insomnia symptoms at the 12-month follow-up after accounting for autoregressive effects. However, the opposite causal model, where baseline insomnia symptoms predicted the chronotype at the 12-month follow-up, was not supported. These findings suggest that a late chronotype may be a potential risk factor for the development of insomnia in young people, emphasising the importance of considering circadian factors in the prevention and treatment of sleep disturbances among this population.

Study Objectives: This study aimed to explore the relationship between post-illumination pupillary response (PIPR) with sleep and circadian measures in a community sample of healthy older adults., Methods: Eligible participants were invited to complete a one-week sleep diary, actigraphy and provide an overnight urine sample to measure urinary 6-sulfatoxymelatonin (aMT6s). PIPR was defined as the as the pupil constriction at 6s post-stimulus (PIPR-6s), and ii) for 30s beginning 10s after stimulus (PIPR-30s) normalized as a percentage to the baseline pupil diameter, after 1s of blue and 1s of red-light stimulus, respectively. The Net-PIPRs were reported by subtracting the PIPR to red stimulus from the PIPR to blue stimulus. The relationship between PIPR metrics to aMT6s and actigraphic rest-activity rhythm parameters was examined by generalized linear models., Results: A total of 48 participants were recruited (Mean age: 62.6 ± 7.1 years, Male: 44%). Both Net PIPR-6s and Net PIPR-30s were significantly associated with actigraphic rest-activity amplitude (B=0.03, p=0.001 and B=0.03, p=0.01, respectively), and actigraphic rest-activity mesor (B=0.02, p=0.001 and B=0.03, p=0.004, respectively). Additionally, the Net PIPR-30s were positively associated with overnight aMT6s level (B=0.04, p=0.03), and negatively associated with actigraphic rest-activity acrophase (B=-0.01, p=0.004) in the fully adjusted models., Conclusion: Attenuated PIPR is associated with a reduced actigraphic amplitude and mesor. The reduced retinal light responsivity may be a potential pathway contributing to impaired photic input to the circadian clock and resulted in the age-related circadian changes in older adults., (© The Author(s) 2024.

Study Objectives: This study assessed the current state of sleep medicine accreditation and training in Asia by conducting a comprehensive survey across 29 Asian countries and regions facilitated by the Asian Society of Sleep Medicine to identify existing gaps and provide recommendations for future enhancements., Methods: The Asian Society of Sleep Medicine Education Task Force Committee designed a survey to gather data on accreditation, education, and training standards in sleep medicine, including information on challenges in enhancing education in the field., Results: With an 86% (25 countries/regions) response rate, the survey showed that sleep medicine is recognized as an independent specialty in just 9 countries/regions (36% of the countries/regions surveyed). Ten countries/regions have established sleep medicine training programs, with Japan and Saudi Arabia offering it as a distinct specialty. Significant disparities in training and accreditation standards were identified, with many countries/regions lacking formalized training and practice guidelines. The survey also revealed that most local sleep societies across Asia support the development of an Asian Sleep Medicine Training Curriculum led by the Asian Society of Sleep Medicine. However, several barriers significantly impede the establishment and development of sleep medicine training programs, including the scarcity of trained specialists and technologists and the absence of national accreditation for sleep medicine., Conclusions: The survey highlights the need for standardized sleep medicine training and accreditation across Asia. Developing an Asian Sleep Medicine Training Curriculum and promoting Asian Society of Sleep Medicine accreditation guidelines are key recommendations. Implementing these strategies is essential for advancing sleep medicine as a widely recognized discipline throughout Asia., Citation: BaHammam AS, Al-Abri MA, Abd Rashid R, et al.

Objective: To explore markers that reflect sleep-disordered breathing (SDB) severity and investigate their associations with cardiometabolic risk factors in adolescents and young adults., Methods: Participants were recruited from our SDB epidemiological cohort. They underwent overnight polysomnography and ambulatory blood pressure (BP) monitoring. Complete blood count, ferritin, high-sensitivity C-reactive protein (hs-CRP), fasting blood glucose, and lipid profile were measured. Multiple linear regression was used to examine the association between red cell indices (RCIs), ferritin, and obstructive apnea-hypopnea index (OAHI). Subgroup analyses on participants with SDB were performed for the association of RCIs and ferritin with lipid profile, hs-CRP, and BP., Results: There were 88 participants with SDB and 155 healthy controls aged 16-25 years. Hemoglobin (Hb; p  < .001), hematocrit (HCT; p  < .001), and ferritin ( p  < .001) were elevated with increasing SDB severity and were independently associated with OAHI (β=1.06, p  < .001; β =40.2, p  < .001; β =4.89 × 10 -3 , p  = .024, respectively). In participants with SDB, after adjusting for age, sex, and BMI, significant associations were found between ferritin with low-density lipoprotein (LDL; β =0.936 × 10 -3 , p  = .008) and triglyceride (TG; β =1.08 × 10 -3 , p  < .001), as well as between Hb ( β =1.40, p  = .007), HCT ( β =51.5, p  = .010) and mean arterial pressure (MAP). Ferritin ( β =0.091, p  = .002), Hb ( β =0.975, p  = .005), and HCT ( β =38.8, p  = .004) were associated with hs-CRP independent of age, sex, BMI, plasma LDL, and MAP. OAHI was not associated with LDL and TG in the multivariable models., Conclusions: Serum ferritin, but not OAHI, was associated with LDL and TG in participants with SDB, suggesting it is a potential marker of cardiometabolic risk in patients with SDB., (© The Author(s) 2024.

Objective: While isolated rapid eye movement sleep behaviour disorder (iRBD) is known as a prodrome of α-synucleinopathies, the prediction for its future phenoconversion to parkinsonism-first or dementia-first subtype remains a challenge. This study aimed to investigate whether visuospatial dysfunction predicts dementia-first phenoconversion in iRBD., Methods: Patients with iRBD and control subjects were enrolled in this prospective cohort study. Baseline neuropsychological assessment included the Unified Parkinson's Disease Rating Scale part III, Montreal Cognitive Assessment (MoCA), Rey-Osterrieth complex figure (ROCF), Colour Trails test (CTT), Farnsworth-Munsell 100-hue test and Digit Span test. The anterior and posterior subscores of MoCA as well as their modified versions were explored. A composite score derived from ROCF and CTT was also explored. Regular follow-up was conducted to determine the phenoconversion status of iRBD patients., Results: The study included 175 iRBD patients and 98 controls. During a mean follow-up of 5.1 years, 25.7% of patients experienced phenoconversion. Most of the neuropsychological tests could differentiate dementia-first but not parkinsonism-first convertors from non-convertors. The modified posterior subscore of MoCA, by integrating the Alternating Trail Making and Clock Drawing components into original the posterior subscore, which mainly reflects visuospatial function, was the strongest predictor for dementia-first phenoconversion (adjusted HR 5.48, 95% CI 1.67 to 17.98)., Conclusion: Visuospatial dysfunction, as reflected mainly by the modified posterior subscore of MoCA, is a predictive factor for dementia-first phenoconversion in iRBD, suggesting its potential for being a biomarker for clinical prognostic prediction and potential neuroprotective trials aiming to delay or prevent dementia., Competing Interests: Competing interests: JW supported by the Faculty Postdoctoral Fellowship Scheme of the Chinese University of Hong Kong and the International Postdoctoral Exchange Fellowship Program (YJ20220085).

Purpose: The purpose of the study was to compare the efficacy of group-based therapy (GT) and email-delivered self-help (ESH) cognitive behavioral therapy for insomnia (CBT-I) with the wait-list (WL) control group in youths., Methods: The study involved an assessor-blind, parallel group randomized controlled trial in youths meeting the diagnostic criteria for insomnia disorder. Participants were randomized to one of the three groups (8-week GT, 8-week ESH, or WL). Participants in all three groups were assessed at baseline and after treatment (week 9 for the WL group). The two treatment groups were additionally assessed at one month and six months after the intervention. Treatment effects were examined using linear mixed models., Results: A total of 135 youths (mean age: 20.0 ± 2.5 years, female: 67.4%) were recruited. After treatment, both active treatment groups showed significant improvements in insomnia symptoms (GT vs. WL: Cohen's d = -1.03, ESH vs. WL: d = -.63), less presleep arousal (d = -.52 to -1.47), less sleep-related dysfunctional belief (d = -.88 to -1.78), better sleep hygiene practice (d = -.79 to -.84), and improved daytime functioning (d = -.56 to -.96) compared with the WL group. In addition, GT outperformed ESH in improving maladaptive sleep-related beliefs and mood symptoms at post-treatment and 6-month follow-up. A reduction of suicidality with moderate effect size favoring GT emerged at 6-month follow-up., Discussion: Our findings suggested that both group-based and email-delivered CBT-I were effective in treating youth insomnia, but group-based CBT-I showed superior effects on reducing maladaptive beliefs and mood symptoms., (Copyright © 2021 Society for Adolescent Health and Medicine.

Chronotype, referred to as an individual's diurnal preference of timing for rest and activity, can be subjectively measured using the Munich Chronotype Questionnaire (MCTQ). However, the validity of MCTQ has yet to be tested in the youth population. In addition, it remains uncertain if MCTQ is a good measure of chronotype in individuals with insomnia. The current study aimed to validate the Chinese version of MCTQ (MCTQ HK ) in the youth population and to explore the utility of MCTQ HK in individuals with insomnia. The original MCTQ was translated into Chinese language using the translation-back-translation method. Part one of this study included 988 youths who completed a battery of self-report questionnaires online consisting of the MCTQ HK and the morningness-eveningness questionnaire (MEQ) for the measures of circadian preference, Insomnia Severity Index (ISI) to assess insomnia symptoms, and Patient Health Questionnaire (PHQ-9) to measure depressive symptoms. Test-retest reliability was examined in 442 participants at one-month follow-up. Of the overall sample, 69 participants were randomly drawn to complete the second part of the study, which included prospective 7-day actigraphy monitoring and a further subset (n = 40) additionally completed a laboratory-based assessment of dim-light melatonin onset (DLMO) as a circadian phase marker. A total of 659 participants with valid responses were finally included in the analyses of the data collected from part one of the study (female = 67.7%; mean age: 20.7 ± 2.02). Results showed that MCTQ parameters, namely the midpoint of sleep on free days (MSF), midpoint of sleep on workdays (MSW), and midpoint of sleep adjusted for sleep debt (MSFsc), were significantly correlated with MEQ score (r = -.514 to -.650, p < .01). Test-retest reliability for MCTQ HK was good (intraclass correlation = 0.75 to 0.84). Later MSFsc was significantly associated with greater insomnia and depressive symptoms after controlling for age and sex. All MCTQ parameters showed significant correlations with actigraphy-based midpoint of sleep and circadian rhythm parameters, i.e., acrophase and L5 onset (r = .362 to .619, p < .01), as well as DLMO (r = .393 to .517, p < .05). The associations remained significant after controlling for age. MSFsc derived from MCTQ was significantly correlated with MEQ score in both the healthy sleepers and participants with insomnia (as defined by ISI > 14), r = -.600, p < .001 and r = -.543, p < .001, respectively. The present study demonstrated that MCTQ HK is suitable for assessing chronotype with good reliability and validity in Chinese youths and supported the utility of MCTQ HK in individuals with insomnia.

Background: Although dysfunction of large-scale brain networks has been frequently demonstrated in patients with α-Synucleinopathy (α-Syn, i.e., Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy), a consistent pattern of dysfunction remains unclear. We aim to investigate network dysfunction in patients with α-Syn through a meta-analysis., Methods: Whole-brain seed-based resting-state functional connectivity studies (published before September 1st, 2020 in English) comparing α-Syn patients with healthy controls (HC) were retrieved from electronic databases (PubMed, Web of Science, and EMBASE). Seeds from each study were categorized into networks by their location within a priori functional networks. Seed-based effect size mapping with Permutation of Subject Images analysis of between-group effects identified the network systems in which α-Syn was associated with hyperconnectivity (increased connectivity in α-Syn vs. HC) or hypoconnectivity (decreased connectivity in α-Syn vs. HC) within and between each seed-network. This study was registered on PROSPERO (CRD42020210133)., Findings: In total, 136 seed-based voxel-wise resting-state functional connectivity datasets from 72 publications (3093 α-Syn patients and 3331 HC) were included in the meta-analysis. We found that α-Syn patients demonstrated imbalanced connectivity among subcortical network, cerebellum, and frontal parietal networks that involved in motor functioning and executive control. The patient group was associated with hypoconnectivity in default mode network and ventral attention network that involved in cognition and attention. Additionally, the patient group exhibited hyperconnectivity between neural systems involved in top-down emotion regulation and hypoconnectivity between networks involved in bottom-up emotion processing., Interpretation: These findings supported neurocognitive models in which network dysfunction is tightly linked to motor, cognitive and psychiatric symptoms observed in α-Syn patients., Funding: This study was partially supported by the Research Grants Council of Hong Kong (Grant No. RGC14116121)., Competing Interests: Declaration of interests J.C. received personal fees from Eisai Co.,Ltd for joining an insomnia expert forum, which is outside the submitted work.

Insomnia is a prevalent sleep problem associated with a constellation of negative health-related outcomes and significant socioeconomic burden. It commonly co-occurs with psychiatric and medical conditions, which may further exacerbate these comorbid conditions and hinder treatment response. There is much empirical evidence to support the clinical efficacy of non-pharmacological treatment for insomnia, especially cognitive behavioral therapy for insomnia (CBT-I), in managing insomnia in a wide range of populations. This article reviews the research on the efficacy of CBT-I for primary insomnia and insomnia comorbid with other psychiatric and medical conditions, the empirical evidence regarding different CBT-I treatment modalities, the implementation of CBT-I across different age groups, and some initial evidence on the sequential combination of insomnia treatments. A brief overview of other non-pharmacological treatment with regard to complementary alternative medicine is also provided.

Objectives: To investigate the association of insomnia and chronotype preference with daytime impairment and psychopathology in a community sample of adolescents in Hong Kong., Methods: This was a cross-sectional study that included seven local secondary schools in Hong Kong. A total of 1667 adolescents (mean age: 14.8 ± 1.6 years old; boys: 56.5%) returned a battery of self-report questionnaires including Insomnia Severity Index (ISI) and reduced Horne and Östberg Morningness and Eveningness Questionnaire (rMEQ) for assessing insomnia symptoms and chronotype preference, respectively. A subset of adolescent samples (n = 768) were additionally assessed for suicidal ideation. Potential confounders including age, gender and sleep duration were controlled for in the analyses., Results: The prevalence of insomnia symptoms and eveningness chronotype was 37% and 25.6%, respectively. Regression models indicated that insomnia and eveningness were independently associated with excessive daytime sleepiness (insomnia: adjusted OR [AdjOR] = 3.8; 95% confidence interval [C.I.] = 2.9-5.0; eveningness: AdjOR = 2.6; 95% C.I. = 1.9-3.7), and an increased risk of depression (insomnia: AdjOR = 3.5, 95% C.I. = 2.5-5.0; eveningness: AdjOR = 2.0, 95% C.I. = 1.3-3.2). The odds ratio increased to 8.7 (95% C.I. = 6.1-12.3, p < 0.001) for excessive daytime sleepiness and 4.8 (95% C.I. = 3.2-7.2, p < 0.001) for depression among adolescents with both insomnia and eveningness. Insomnia symptoms, but not eveningness, were associated with anxiety symptoms (AdjOR = 5.8; 95% C.I. = 3.6-9.4) and suicidal ideation (AdjOR = 2.1, 95% C.I. = 1.4-3.2)., Conclusions: The present study provided further evidence that insomnia and eveningness uniquely contributed to poor daytime functioning and mood related outcomes, while the co-existence of these two conditions could confer a greater risk in adolescents. However, insomnia, but not eveningness, was significantly linked to suicidality after controlling for mood symptoms. Our findings highlighted the necessity of timely management of sleep and circadian issues in adolescents., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Background: Aging is characterized by cognitive changes in specific domains, such as declines in memory and executive functions. Given the world's aging population, it is important to identify and evaluate strategies that promote healthy cognitive aging. Besides exercise, computerized cognitive training (CCT) is a promising approach to promote cognitive function. Moreover, a single bout of exercise immediately prior to CCT may provide additional cognitive benefits., Methods: An 8-week proof-of-concept randomized controlled trial to investigate the effect of a commercial CCT intervention, alone and when preceded by exercise, on cognitive function. Participants (124; aged 65-85 years) performed 8 weeks of: (i) Group-based CCT (Fit Brains) 3×/week for 1 hour plus 3×/week home-based training; (ii) Group-based CCT preceded by exercise (Ex-CCT) 3×/week for 1 hour plus 3×/week home-based training (exercise+CCT); or (iii) Group-based balanced and toned (BAT) classes 3×/week for 1 hour (control). Memory was assessed by the Rey Auditory Verbal Learning Test. Executive functions were assessed using the: (i) Stroop Test, (ii) Trail Making Tests (TMT), (iii) Flanker Test, and (iv) Dimensional Change Card Sort Test (DCCS)., Results: At trial completion, there were no significant between-group differences in memory (p > .05). However, compared with BAT, CCT, and Ex-CCT significantly improved Stroop performance (-10.72, 95% confidence interval [CI]: -16.53, -4.91; -7.95, 95% CI: -13.77, -2.13, respectively). Moreover, Ex-CCT significantly improved the performance on TMT (-13.65, 95% CI: -26.09, -1.22), the Flanker Test (6.72, 95% CI: 2.55, 10.88), and the DCCS Test (6.75, 95% CI: 0.99, 12.50)., Conclusion: An 8-week CCT program may promote executive functions in older adults and combining it with a bout of exercise may provide broader benefits., (© The Author(s) 2019.

Introduction: There are contradictory findings regarding the associations of parental depression on the hypothalamic-pituitary-adrenal axis activity of their offspring. We aimed to explore the associations of parental depression on the diurnal salivary cortisol profile in their child and adolescent offspring., Methods: A total of 189 unaffected child and adolescent offspring as determined by structured clinical interview were divided into 3 groups according to their parental history of depression, namely current parental depression (CPD, n = 27), past parental depression (PPD, n = 57), and no parental depression (NPD, n = 105). Diurnal saliva samples were collected to measure the cortisol awakening response and diurnal cortisol profile., Results: CPD group had significantly higher basal cortisol level (mean ± SE = 11.9 ± 0.80 nmol/dl) than PPD group (mean ± SE = 9.7 ± 0.73 nmol/dl, post hoc p = .024) and NPD group (mean ± SE = 10.2 ± 0.52 nmol/dl, post hoc p = .031) and lower cortisol level at noon, but comparable cortisol levels in other time points. The cortisol awakening response reference to increase (AUCi) were significantly blunted in CPD group when compared with PPD and NPD (post hoc p < .01). Adjustment for potential confounding factors did not change major findings. Further analyses revealed that main influences were derived from current maternal depression., Limitations: A single day of saliva sample., Conclusion: Current but not past (lifetime) parental depression is associated with higher basal salivary cortisol and blunted cortisol awakening response in their children and adolescents., (Copyright © 2018 Elsevier B.V.

Background and Aims: Mucosal healing is the goal for ulcerative colitis (UC) therapy, but it needs to be confirmed via colonoscopy. Colon capsule endoscopy (CCE) is a noninvasive technique for colon investigation. Our study investigated the accuracy of second-generation CCE (CCE-2) in assessing mucosal lesions and disease activity in UC., Methods: In this prospective study, CCE-2 and conventional colonoscopy were performed on the same day. CCE-2 reviewers and colonoscopists used the Mayo endoscopic subscore (MES) and the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) to assess disease activity, and they were blinded to each other's findings. Diagnostic parameters of CCE-2 for identifying mucosal lesions were evaluated by using colonoscopy as the reference., Results: A total of 150 patients were enrolled. Of the 150 patients, 108 were included for per-patient analysis. CCE-2 and colonoscopy showed substantial agreement in measuring MES (intraclass correlation coefficient [ICC] 0.69; 95% confidence interval [CI], 0.46-0.81; P < .001) and UCEIS (ICC 0.64; 95% CI, 0.38-0.78; P < .001). CCE-2 had a sensitivity of 97% and 94% to detect mucosal inflammation (MES >0) and moderate to severe inflammation (MES >1), respectively. In per-segment analysis, the negative predictive values of CCE-2 to detect mucosal inflammation, including vascular pattern loss, bleeding, and erosions reached 94% to 95%. Interobserver agreement between 2 independent CCE-2 readers for both scoring systems was good (ICC > .80). The sensitivity and specificity of CCE-2 in detecting postinflammatory polyps were 100% and 91%, respectively. CCE-2 was better tolerated and preferred by patients than was colonoscopy., Conclusions: CCE-2 yields high accuracy in detecting mucosal lesions and determining disease severity in UC. It represents a well-tolerated and reliable tool for disease monitoring in UC. (Clinical trial registration number: NCT02469103.)., (Copyright © 2017 American Society for Gastrointestinal Endoscopy.

Objectives: To determine the prevalence and correlates of help-seeking behaviors for insomnia in Hong Kong Chinese middle-aged adults and their offspring., Methods: A total of 2231 middle-aged adults (54.2% females, mean age 45.8 years) and 2186 children and adolescents (51.9% females, mean age 13.4 years) completed a questionnaire on insomnia symptoms, daytime functioning, health condition and treatments sought for insomnia., Results: A total of 40% of adults and 10% of children and adolescents with insomnia reported having sought treatment for insomnia. Conventional Western medicine was the commonly preferred treatment in 33.3% of adults and 13.3% of children and adolescents who sought help for insomnia, while a higher proportion of individuals with insomnia (34.5% of adults and 26.7% of children and adolescents) sought help from complementary and alternative medicine (CAM) therapies. Female gender (odds ratio [OR] [95% confidence interval, CI] = 2.14 [1.01-4.53]), higher family income (≥15,000 HKD/month) (OR [95% CI] = 3.15 [1.27-6.34]), severity of insomnia (Insomnia Severity Index ≥14) (OR [95% CI] = 2.12 [1.10-4.12]), chronic medications (OR [95% CI] = 4.71 [2.27-9.79]), and psychiatric disorders (OR [95% CI] = 2.83 [1.01-7.96]) were associated with help-seeking behaviors in adults. Presence of morning headache was associated with help-seeking behaviors in children and adolescents (OR [95% CI] = 8.66 [1.72-43.70])., Conclusions: It is uncommon for Hong Kong Chinese to seek help for insomnia, despite the high prevalence of insomnia. The significant unmet need argues for timely intervention to promote sleep-health literacy and to enhance the awareness and accessibility of evidence-based treatment for insomnia., (Copyright © 2016 Elsevier B.V.

Background: Rapid eye movement sleep behavior disorder (RBD) is characterized by prominent dream-enacting behaviors, often resulting in sleep-related injuries., Objectives: This study aimed to prospectively examine the treatment response of people with RBD treated with clonazepam, by quantitatively delineating the characteristic changes in the clinical and polysomnographic features, and to explore the factors associated with this response., Methods: Patients diagnosed with idiopathic RBD (iRBD) were consecutively recruited and invited to complete clinical and polysomnographic (PSG) assessments and self-administered questionnaires (including the modified REM Sleep Behavior Questionnaire, RBDQ-3M) before and after the initiation of treatment with clonazepam., Results: Thirty-nine iRBD patients (male: 74.4%, mean age at diagnosis: 68.3 ± 7.8 years) were recruited with a follow-up duration of 28.8 ± 13.3 months. Clonazepam was offered as the first-line treatment (starting dose: 0.43 ± 0.16 mg, range: 0.125-1.00; dose at follow-up: 0.98 ± 0.63 mg, range: 0.125-3). Treatment response, as defined by a complete elimination of sleep-related injuries and potentially injurious behaviors to self and/or to bed partner, at follow-up was reported in 66.7% of the overall study subjects. Frequency of disturbing dreams with violent and frightening content and vigorous behavioral RBD symptoms was significantly reduced, while residual nocturnal symptoms and an increase in REM-related EMG activities were observed at follow-up. Less optimal treatment outcomes were found to be associated with the presence of comorbid obstructive sleep apnea and earlier onset of RBD., Conclusions: Clonazepam differentially changes dream affect and content, as well as reduces vigorous verbal and motor behaviors. Residual RBD symptoms are common, despite treatment. Other more effective alternative or adjunctive interventions are needed for better clinical management of RBD., (Copyright © 2016 Elsevier B.V.

Background: The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) recommend the use of alcohol handrubs to prevent health care-associated infections. However, the efficacy and time effectiveness of different alcohol handrubbing protocols have yet to be evaluated., Methods: We conducted a randomized controlled trial in the general wards of a 1,300-bed, acute, tertiary care hospital to compare the effectiveness of 3 hand hygiene protocols during routine inpatient care: (1) handrubbing with alcohol covering all hand surfaces, (2) handrubbing with alcohol using the standard 7-step technique, and (3) handwashing with chlorhexidine using the standard 7-step technique. Hand samples were obtained from 60 medical and 60 nursing staff, before and after hand hygiene. Quantitative and qualitative bacterial evaluations were carried out by microbiologists blinded to the protocol., Results: All 3 protocols were effective in reducing hand bacterial load (P < .01). During routine patient care, alcohol handrubbing covering all hand surfaces required less time (median, 26.0 seconds) than alcohol handrubbing using the 7-step technique (median 38.5 seconds; P = .04) and chlorhexidine handwashing (median, 75.5 seconds; P < .001)., Conclusion: Alcohol handrubbing protocols are as efficacious as chlorhexidine handwashing. Alcohol handrubbing covering all hand surfaces is the most time-effective protocol for routine patient care activities in busy general wards., (Copyright © 2012 Association for Professionals in Infection Control and Epidemiology, Inc.
