    Sleep disorder is a symptom of many neurological diseases that may significantly affect the quality of daily life. Traditional methods are time-consuming and involve the manual scoring of polysomnogram (PSG) signals obtained in a laboratory environment. However, the automated monitoring of sleep stages can help detect neurological disorders accurately as well. In this study, a flexible deep learning model is proposed using raw PSG signals. A one-dimensional convolutional neural network (1D-CNN) is developed using electroencephalogram (EEG) and electrooculogram (EOG) signals for the classification of sleep stages. The performance of the system is evaluated using two public databases (sleep-edf and sleep-edfx). The developed model yielded the highest accuracies of 98.06%, 94.64%, 92.36%, 91.22%, and 91.00% for two to six sleep classes, respectively, using the sleep-edf database. Further, the proposed model obtained the highest accuracies of 97.62%, 94.34%, 92.33%, 90.98%, and 89.54%, respectively for the same two to six sleep classes using the sleep-edfx dataset. The developed deep learning model is ready for clinical usage, and can be tested with big PSG data.

    INTRODUCTION: Community pharmacists are in a suitable position to give advice and provide appropriate services related to sleep disorders to individuals who are unable to easily access sleep clinics. An intervention with proper objective measure can be used by the pharmacist to assist in consultation.
    OBJECTIVES: The study objectives are to evaluate: (1) The effectiveness of a community pharmacy-based intervention in managing sleep disorders and (2) the role of actigraph as an objective measure to monitor and follow-up individuals with sleeping disorders.
    METHODS AND INSTRUMENTS: The intervention care group (ICG) completed questionnaires to assess sleep scale scores (Epworth Sleepiness Scale [ESS] and Insomnia Severity Index [ISI]), wore a wrist actigraph, and completed a sleep diary. Sleep parameters (sleep efficiency in percentage [SE%], total sleep time, sleep onset latency, and number of nocturnal awakenings) from actigraphy sleep report were used for consultation and to validate sleep diary. The usual care group (UCG) completed similar questionnaires but received standard care.
    RESULTS: Pre- and post-mean scores for sleep scales and sleep parameters were compared between and within groups. A significant difference was observed when comparing pre- and post-mean scores for ISI in the ICG, but not for ESS. For SE%, an increase was found in the number of subjects rated as "good sleepers" at post-assessment in the ICG.
    CONCLUSIONS: ISI scores offer insights into the development of a community pharmacy-based intervention for sleeping disorders, particularly in those with symptoms of insomnia. It also demonstrates that actigraph could provide objective sleep/wake data to assist community pharmacists during the consultation.

    BACKGROUND: Pruritus adds to the complications of chronic kidney disease (CKD) patient and a well-recognized complication among the CKD patients. Majority of the patients on hemodialysis experience a generalized pruritus and patients reported being moderately to extremely disturbed by at least one of the sleep-related condition. This study aim to investigate the effectiveness of zolpidem 10 mg and acupressure therapy on foot acupoints to improve the sleep quality and overall quality of life among hemodialysis patients suffering from CKD-associated pruritus.

    METHODS: A multicentered, open-label, parallel group, prospective randomized controlled trial among patients suffering from CKD-associated pruritus with sleep disturbance, after randomization into control, and intervention group to be held at North West General Hospital and Research Center Peshawar, Pakistan and Institute of Kidney Diseases Peshawar, Pakistan.

    RESULTS: The primary outcome is to investigate the effectiveness of zolpidem 10 mg and acupressure therapy on foot acupoints to improve the sleep quality and overall quality of life among hemodialysis patients suffering from CKD-associated pruritus. After baseline assessment by Urdu version of 5D itch scale and Urdu version of Pittsburgh Sleep Quality Index (PSQI) and Urdu EQ-5D 3L, the intervention group will be given zolpidem 10 mg oral tablets and control group with acupressure on both foots on KI-1 acupoints for total of 6 minutes. Assessment will be done at weeks 4 and 8 from baseline by using Urdu version of 5D itch scale and Urdu version of PSQI and Urdu EQ-5D 3L, whereas safety profiling of zolpidem 10 mg tablet at week 6 from baseline and acupressure acceptability at week 6 from baseline. Analysis of covariance will be used to examine the differences in treatment effects between the intervention and control groups.

    CONCLUSION: Improvement of sleep quality and quality of life among patients with CKD-associated pruritus requires great importance. This study aims to improve the quality of sleep and quality of life among patients with hemodialysis suffering from CKD-associated pruritus.

    Sleep is an essential biological phase of our daily life cycle and is necessary for maintaining homeostasis, alertness, metabolism, cognition, and other key functions across the animal kingdom. Dysfunctional sleep leads to deleterious effects on health, mood, and cognition, including memory deficits and an increased risk of diabetes, stroke, and neurological disorders. Sleep is regulated by several brain neuronal circuits, neuromodulators, and neurotransmitters, where cannabinoids have been increasingly found to play a part in its modulation. Cannabinoids, a group of lipid metabolites, are regulatory molecules that bind mainly to cannabinoid receptors (CB1 and CB2). Much evidence supports the role of cannabinoid receptors in the modulation of sleep, where their alteration exhibits sleep-promoting effects, including an increase in non-rapid-eye movement sleep and a reduction in sleep latency. However, the pharmacological alteration of CB1 receptors is associated with adverse psychotropic effects, which are not exhibited in CB2 receptor alteration. Hence, selective alteration of CB2 receptors is also of clinical importance, where it could potentially be used in treating sleep disorders. Thus, it is crucial to understand the neurobiological basis of cannabinoids in sleep physiology. In this review article, the alteration of the endocannabinoid system by various cannabinoids and their respective effects on the sleep-wake cycle are discussed based on recent findings. The mechanisms of the cannabinoid receptors on sleep and wakefulness are also explored for their clinical implications and potential therapeutic use on sleep disorders.

    OBJECTIVE: To assess the effectiveness and feasibility of behavioral sleep intervention for medicated children with ADHD.

    METHOD: Six medicated children (five boys, one girl; aged 6-12 years) with ADHD participated in a 4-week sleep intervention program. The main behavioral strategies used were Faded Bedtime With Response Cost (FBRC) and positive reinforcement. Within a case-series design, objective measure (Sleep Disturbance Scale for Children [SDSC]) and subjective measure (sleep diaries) were used to record changes in children's sleep.

    RESULTS: For all six children, significant decrease was found in the severity of children's sleep problems (based on SDSC data). Bedtime resistance and mean sleep onset latency were reduced following the 4-week intervention program according to sleep diaries data. Gains were generally maintained at the follow-up. Parents perceived the intervention as being helpful.

    CONCLUSION: Based on the initial data, this intervention shows promise as an effective and feasible treatment.

    INTRODUCTION: Allergic rhinitis (AR) is a prevalent disease worldwide but is still underdiagnosed in many parts of Asia. We studied the clinical profiles of AR patients in our community based on the new ARIA classification and investigated the aetiological allergens using a skin prick test.

    MATERIALS AND METHODS: In 2008, 142 newly diagnosed patients with AR were seen and underwent skin prick testing with 90 patients completing the study.

    RESULTS: Intermittent mild and moderate/severe AR were evident in 10% and 21.1% of the patients, while persistent mild and moderate/severe were seen in 20% and 48.9%, respectively. Rhinitis and asthma co-morbidity occurred in 28.8% with asthma incidence significantly higher in persistent AR (P = 0.002). There was no significant association between AR severity, city living and asthma co-morbidity. Nasal itchiness and sneezing were the main presenting complaints and were more common in intermittent AR (P <0.05). Sleep disturbance was associated with moderate-severe AR (P <0.05). Polypoidal mucosa was associated with asthma co-morbidity (P <0.05). Monosensitivity reaction occurred in 12.2% of patients and was associated with fungi sensitivity (P <0.05). Majority of patients were oligosensitive (52.8%) and polysensitive (34.4%) and were significantly associated with moderate-severe persistent AR (P <0.01). The highest positive skin prick reaction and the largest average wheal diameter were for the house dust mites and cat allergen (P <0.05).

    CONCLUSION: Our results reflected the AR profiles in our country, which was comparable with typical profiles of the neighbouring country and other Mediterranean countries with a similar temperate climate.

    BACKGROUND:
    To characterize cross-cultural sleep patterns and sleep problems in a large sample of children ages birth to 36 months in multiple predominantly-Asian (P-A) and predominantly-Caucasian (P-C) countries.

    METHODS:
    Parents of 29,287 infants and toddlers (predominantly-Asian countries/regions: China, Hong Kong, India, Indonesia, Korea, Japan, Malaysia, Philippines, Singapore, Taiwan, Thailand, Vietnam; predominantly-Caucasian countries: Australia, Canada, New Zealand, United Kingdom, United States) completed an internet-based expanded version of the Brief Infant Sleep Questionnaire.

    RESULTS:
    Overall, children from P-A countries had significantly later bedtimes, shorter total sleep times, increased parental perception of sleep problems, and were more likely to both bed-share and room-share than children from P-C countries, psleep time from 11.6 (Japan) to 13.3 (New Zealand) hours, psleep. Bed-sharing with parents ranged from 5.8% in New Zealand to 83.2% in Vietnam. There was also a wide range in the percentage of parents who perceived that their child had a sleep problem (11% in Thailand to 76% in China).

    CONCLUSIONS:
    Overall, children from predominantly-Asian countries had significantly later bedtimes, shorter total sleep times, increased parental perception of sleep problems, and were more likely to room-share than children from predominantly-Caucasian countries/regions. These results indicate substantial differences in sleep patterns in young children across culturally diverse countries/regions. Further studies are needed to understand the basis for and impact of these interesting differences.

    Poor sleep quality and daytime somnolence is reported to be associated with cardiovascular events, road traffic accident, poor academic performance and psychological distress. Some studies documented that it is prevalent in most populations but its frequency among medical students has not been documented in Malaysia. This is a self-administered questionnaire survey of medical students from International Medical University, Malaysia. Daytime sleepiness of medical students was assessed using Epworth Sleepiness Scale (ESS). Student scoring ESS > 11 was regarded as having excessive daytime sleepiness. Psychological distress was measured using 12-item General Health Questionnaire (GHQ-12). A total of 799 medical students participated in this survey (response rate 69.5%). Daytime sleepiness occurred in 35.5%, psychological distress was present in 41.8% and 16.1% reported bad sleep quality. Daytime sleepiness was significantly more common among the clinical students, those with self-reported bad sleep quality and psychological distress; but unrelated to the number of hours sleep at night. We have documented high prevalence of daytime sleepiness, poor sleep quality and psychological distress. Higher frequency among clinical students and the significant relationship with psychological distress suggest possible link to the stressful clinical training.

    Sleep disorder including insomnia is one of the complications of general anaesthesia. It is not uncommon and it is temporary but majority remains unnoticed and untreated. The effect of insomnia ranges from mild to severe, influencing both physical and mental health. Surgeon and anaesthetist need to identify this complication so that an appropriate treatment can be delivered. In complicated case, psychiatrist involvement is crucial. The treatment is symptomatic and temporary. We reported a case of distressful sleep disorder as a sequelae of general anaesthesia for mastoidectomy surgery. Subsequently after symptomatic treatment, he recovered completely and regained his normal sleep pattern.

    The development of overweight and obesity among women in Malaysia has shown an increasing trend between the year 2003 and 2014 base on the Malaysian Adult Nutrition Survey report in 2015. The prevalence of obesity was significantly higher in women by 22.9% compared to men 14.5%. There are many factors contributing to the upsurge of obesity among women and among most, sleep disorders has been the emerging issue which has longed been discussed. Certain important factors affecting women related to sleep quality such as stress, insomnia, depression and some biological conditions like menopause, menstrual cycle and pregnancy can affect sleep quality. This paper serves to review how lack of sleep quality is associated to the development of obesity and why healthy sleep behaviour could aid to weight loss. Public health approaches to reducing the burden of obesity must consider equipping the women in managing their sleep related issues and how they are able to control the food consumption and lifestyle of the family. Thus, promoting healthy sleep behaviour among women emphasized on the importance of deriving sleep quality through three important factors that is early bed time, sleep in the dark and sleep duration would be a contributing factor in managing obesity through healthy lifestyle changes.

    : Chronic kidney disease (CKD)-associated pruritus is a common and disturbing condition which has a negative impact on sleep quality, as well as overall health-related quality of life of patients receiving hemodialysis. To date, no systematic review has been undertaken, and there is a lack of concise evidence that statistically quantifies the impact of pruritus based on published data. A systematic search was done for original articles published in peer-reviewed English journals from database inception on 20 December, 2018, in the following databases: PubMed, MEDLINE, EMBASE, Ovid, CINHAL, ProQuest, and Scopus. A total of 9217 research articles were identified. After removal of duplicates and screening for titles and abstracts, 28 articles were selected. The prevalence of disturbed sleep was 4-94%, while the pooled proportion on random effect in the study was 40% (95% CI = 0.30 to 0.49); I2 = 99.8%. However, the prevalence of disturbed sleep quality and quantity due to pruritus was 9-76%, and the pooled proportion on random effect in the study was 50% (95% CI = 0.37 to 0.64); I2 = 99.8%. Patients undergoing hemodialysis who are affected by CKD-associated pruritus have a higher chance of experiencing sleep disturbances. The prevalence of disturbed sleep due to CKD-associated pruritus was found to be 9-76% in the included studies for patients receiving hemodialysis therapy.

    This study aimed to determine the effects of diabetes mellitus (DM), hypertension (HT), heart disease, social isolation, and sociodemographic factors on sleep in the elderly patients with dementia. Samples included 1210 noninstitutionalized, Malaysian elderly patients with dementia. The multiple logistic regression analysis was applied to estimate the risk of sleep disturbances among respondents. Approximately 41% of the patients experienced sleep problems. The results showed that age (odds ratio [OR] = 1.02), social isolation (OR = 1.33), and HT (OR = 1.53) significantly increased sleep disruption in respondents (P sleep problems (P sleep disturbances (P >.05). It was concluded that age, social isolation, and HT increased sleep disruption but education and ethnic non-Malay reduced the risk of sleep problems. Moreover, HT was the most important variable to increase sleep disturbances in the elderly patients with dementia.

    Objective: The objective of this study is to determine the frequency and correlates of insomnia among elderly patients presenting to family medicine clinics at an academic center in Karachi, Pakistan.

    Study design: This is a cross-sectional study.

    Place and duration of study: The study was conducted at the Outpatient Family Medicine Clinics at Aga Khan University Hospital between February 2013 and June 2013.

    Methodology: Patients 60 years old and above were recruited (n=152) through non- probability consecutive sampling. Information was collected on a pretested structured questionnaire on demographics, insomnia symptoms, medical co-morbidities, lifestyle factors and sleep disorders. Data was analyzed on SPSS 19. Proportions and the Chi-Square test were used in the analyses, along with binary logistic regression.

    Results: The mean age of the participants was 65.68 years, and 38.80% of the participants were male and 61.20% were female. The prevalence of insomnia was 42.1%. It was more common in women than in men (64.10% vs. 35.9%). Increasing age [ORadj: 4.54; 95%CI: 1.85-11.17], being divorced/widowed [ORadj: 10.26; 95%CI: 2.79-37.73] and having an average household income of over Rs.50, 000, were significantly related to insomnia. The other factors associated with insomnia were Gastro Esophageal Reflux Disease [ORadj: 4.30; 95% CI: 1.67-11.04], depression [ORadj: 2.88, 95% CI: 1.13-7.33], caffeine consumption [ORadj: 6.50; 95% CI: 2.27-18.57], and cigarette smoking close to bed time [ORadj: 4.78; 95% CI: 0.88-25.90].

    Conclusion: The study showed that older adults with multiple diseases were at high risk of insomnia. Certain life style practices enhanced the risk; hence, physicians should incorporate sleep history and tailor treatment to target both insomnia and related factors to optimize quality of life.

    Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by sleep, behavioral, memory, and cognitive deteriorations. Sleep disturbance (SD) is a major disease burden in AD, which has a reciprocal relationship with AD pathophysiology. It aggravates memory, behavioral, and cognitive complications in AD. Different studies have found that melatonin hormone levels reduce even in the pre-clinical stages of AD. Melatonin is the primary sleep-regulating hormone and a potent antioxidant with neuroprotective roles. The decrease in melatonin levels can thus promote SD and AD neuropathology. Exogenous melatonin has the potential to alleviate neuropathology and SD in AD by different mechanisms. Various studies have been conducted to assess the efficacy of exogenous melatonin to treat SD in AD. Though most of the studies suggest that melatonin is useful to ameliorate SD in AD, the remaining studies show opposite results. The timing, dosage, and duration of melatonin administration along with disease condition, genetic, environmental, and some other factors can be responsible for the discrepancies between the studies. More extensive trials with longer durations and higher dosage forms and studies including bright light therapy and melatonin agonists (ramelteon, agomelatine, and tasimelteon) should be performed to determine the efficacy of melatonin to treat SD in AD.

    Background: Listening to music is often used as a self-help intervention to improve sleep quality, but its efficacy among individuals without sleep disorder remains unclear.Methods: A search was performed on five databases to identify for studies that examined the use of music-based intervention to improve sleep quality among individuals without sleep disorder. Random-effects meta-analysis was performed, and the certainty of evidence was evaluated using GRADE (Grading of Recommendations Assessment, Development and Evaluation).Results: Twenty-two articles which recruited 1,514 participants were included for review. Meta-analysis of six studies including 424 participants did not find an improvement in sleep quality among recipients of music-based intervention compared to those with standard care (mean difference: -0.80; 95% CI: -2.15 to 0.54, low-quality evidence). Subgroup analysis showed a clear improvement in sleep quality when interventions were administered for at least 3 weeks (-2.09; -3.84 to -0.34, n = 3). No difference in terms of sleep onset latency (standardized mean difference (SMD) -0.32; 95% CI -0.88 to 0.25, n = 4, very-low quality evidence) and sleep efficiency (SMD: -0.59; 95% CI -3.15 to 1.97, n = 2, very-low quality evidence) were observed. The effect of music-based intervention on anxiety, depression and quality of life were mixed with suggestions of possible benefits.Conclusion: Music-based intervention in addition to standard care appears to be a promising strategy to improve sleep quality when delivered for 3 week or longer. However, effects are inconsistent across studies and larger randomized controlled studies reporting long-term outcomes are needed before it can be recommended for routine use.PROSPERO registration: CRD42018081193.

    Parkinson's disease (PD) is a neurodegenerative disease of the central nervous system caused due to the loss of dopaminergic neurons. It is classified under movement disorder as patients with PD present with tremor, rigidity, postural changes, and a decrease in spontaneous movements. Comorbidities including anxiety, depression, fatigue, and sleep disorders are observed prior to the diagnosis of PD. Gene mutations, exposure to toxic substances, and aging are considered as the causative factors of PD even though its genesis is unknown. This paper reviews PD etiologies, progression, and in particular measurable indicators of PD such as neuroimaging and electrophysiology modalities. In addition to gene therapy, neuroprotective, pharmacological, and neural transplantation treatments, researchers are actively aiming at identifying biological markers of PD with the goal of early diagnosis. Neuroimaging modalities used together with advanced machine learning techniques offer a promising path for the early detection and intervention in PD patients.

    Profound disturbances in sleep architecture occur in major depressive disorders (MDD) and in bipolar affective disorders. Reduction in slow wave sleep, decreased latency of rapid eye movement (REM) sleep and abnormalities in the timing of REM/non-REM sleep cycles have all been documented in patients with MDD. It is thus evident that an understanding of the basic mechanisms of sleep regulation is essential for an analysis of the pathophysiology of depressive disorders. The suprachiasmatic nucleus (SCN), which functions as the body's master circadian clock, plays a major role in the regulation of the sleep/wakefulness rhythm and interacts actively with the homeostatic processes that regulate sleep. The control of melatonin secretion by the SCN, the occurrence of high concentrations of melatonin receptors in the SCN, and the suppression of electrical activity in the SCN by melatonin all underscore the major influence which this neurohormone has in regulating the sleep/wake cycle. The transition from wakefulness to high sleep propensity is associated with the nocturnal rise of endogenous melatonin secretion. Various lines of evidence show that depressed patients exhibit disturbances in both the amplitude and shape of the melatonin secretion rhythm and that melatonin can improve the quality of sleep in these patients. The choice of a suitable antidepressant that improves sleep quality is thus important while treating a depressive disorder. The novel antidepressant agomelatine, which combines the properties of a 5-HT(2C) antagonist and a melatonergic MT(1)/MT(2) receptor agonist, has been found very effective for resetting the disturbed sleep/wake cycle and in improving the clinical status of MDD. Agomelatine has also been found useful in treating sleep problems and improving the clinical status of patients suffering from seasonal affective disorder.

    Aim: The aim of this study was to examine patients' and physicians' satisfaction, and concordance of patient-physician satisfaction with patients' pain control status.

    Methods: This cross-sectional observational study involved 465 adults prescribed analgesics for cancer-related pain from 22 sites across Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. Pain intensity, pain control satisfaction, and adequacy of analgesics for pain control were documented using questionnaires.

    Results: Most patients (84.4%) had stage III or IV cancer. On a scale of 0 (no pain) to 10 (worse pain), patients' mean worst pain intensity over 24 hours was 4.76 (SD 2.47). More physicians (19.0%) than patients (8.0%) reported dissatisfaction with patient's pain control. Concordance of patient-physician satisfaction was low (weighted kappa 0.36; 95% CI 0.03-0.24). Most physicians (71.2%) found analgesics to be adequate for pain control. Patients' and physicians' satisfaction with pain control and physician-assessed analgesic adequacy were significantly different across countries (P < 0.001 for all).

    Conclusions: Despite pain-related problems with sleep and quality of life, patients were generally satisfied with their pain control status. Interestingly, physicians were more likely to be dissatisfied with patients' pain control.
