Review
BACKGROUND
Lewy body dementia (LBD) refers to both dementia with Lewy bodies (DLB) and Parkinson's disease with dementia (PDD). Sleep disturbances are common in LBD, and can include poor sleep quality, excessive daytime sleepiness (EDS), and rapid eye movement behaviour disorder (RBD). Despite the high clinical prevalence of sleep disturbances in LBD, they are under-studied relative to other dementias. The aim of the present systematic review was to examine the nature of sleep disturbances in LBD, summarise the effect of treatment studies upon sleep, and highlight specific and necessary directions for future research.
METHODS
Published studies in English were located by searching PubMED and PSYCArticles databases (until 10 June 2022). The search protocol was pre-registered in PROSPERO (CRD42021293490) and performed in accordance with PRISMA guidelines.
RESULTS
Following full-text review, a final total of 70 articles were included. These included 20 studies focussing on subjective sleep, 14 on RBD, 8 on EDS, 7 on objective sleep, and 1 on circadian rhythms. The majority of the 18 treatment studies used pharmacological interventions (n = 12), had an open-label design (n = 8), and were of low-to-moderate quality. Most studies (n = 55) included only patients with DLB. Due to the heterogeneity of the studies, we reported a narrative synthesis without meta-analysis.
CONCLUSIONS
At least one form of sleep disturbance may be present in as many as 90% of people with LBD. Subjectively poor sleep quality, excessive daytime sleepiness, and RBD are more common and severe in LBD relative to other dementias.

Meta-Analysis
Comparative Efficacy and Safety of Wakefulness-Promoting Agents for Excessive Daytime Sleepiness in Patients With Obstructive Sleep Apnea : A Systematic Review and Network Meta-analysis.
BACKGROUND
Excessive daytime sleepiness (EDS) is common among patients with obstructive sleep apnea (OSA). The comparative effectiveness of pharmacologic agents is unknown.
PURPOSE
To compare the effectiveness of drugs for EDS in OSA using network meta-analysis.
DATA SOURCES
MEDLINE, CENTRAL, EMBASE, and ClinicalTrials.gov to 7 November 2022.
STUDY SELECTION
Reviewers identified randomized trials that enrolled patients with EDS-associated OSA on or eligible for conventional therapy assigned to any pharmacologic intervention.
DATA EXTRACTION
Paired reviewers independently extracted data addressing effects of drugs on the Epworth Sleepiness Scale (ESS), Maintenance of Wakefulness Test (MWT), and adverse events at the longest reported follow-up. The certainty of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach.
DATA SYNTHESIS
Fourteen trials (3085 patients) were eligible. At 4 weeks, compared with placebo, solriamfetol improves ESS scores (mean difference [MD], -3.85 [95% CI, -5.24 to -2.50]; high certainty), and armodafinil-modafinil (MD, -2.25 [CI, -2.85 to -1.64]; moderate certainty) and pitolisant-H3-autoreceptor blockers (MD, -2.78 [CI, -4.03 to -1.51]; moderate certainty) probably improve ESS scores. At 4 weeks, compared with placebo, solriamfetol (standardized mean difference [SMD], 0.9 [CI, 0.64 to 1.17]) and armodafinil-modafinil (SMD, 0.41 [CI, 0.27 to 0.55]) improve MWT (both high certainty), whereas pitolisant-H3-autoreceptor blockers probably do not (moderate certainty). At 4 weeks, armodafinil-modafinil probably increases the risk for discontinuation due to adverse events (relative risk [RR], 2.01 [CI, 1.14 to 3.51]; moderate certainty); solriamfetol may increase the risk for discontinuation due to adverse events (RR, 2.07 [CI, 0.67 to 6.25]; low certainty). Low certainty evidence suggests these interventions may not increase the risk for serious adverse events.
LIMITATIONS
There is limited evidence on long term or effectiveness among patients nonadherent or with mixed adherence to conventional OSA therapies.
CONCLUSION
Solriamfetol, armodafinil-modafinil, and pitolisant reduce daytime sleepiness for patients with OSA already on conventional therapy, with solriamfetol likely superior. Adverse events probably increase the risk for discontinuation of armodafinil-modafinil and may increase the risk for discontinuation with solriamfetol.

Meta-Analysis
BACKGROUND
This review updates part of an earlier Cochrane Review titled "Pregabalin for acute and chronic pain in adults", and considers only neuropathic pain (pain from damage to nervous tissue). Antiepileptic drugs have long been used in pain management. Pregabalin is an antiepileptic drug used in management of chronic pain conditions.
OBJECTIVES
To assess the analgesic efficacy and adverse effects of pregabalin for chronic neuropathic pain in adults.
SEARCH METHODS
We searched CENTRAL, MEDLINE, and Embase for randomised controlled trials from January 2009 to April 2018, online clinical trials registries, and reference lists.
SELECTION CRITERIA
We included randomised, double-blind trials of two weeks' duration or longer, comparing pregabalin (any route of administration) with placebo or another active treatment for neuropathic pain, with participant-reported pain assessment.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted data and assessed trial quality and biases. Primary outcomes were: at least 30% pain intensity reduction over baseline; much or very much improved on the Patient Global Impression of Change (PGIC) Scale (moderate benefit); at least 50% pain intensity reduction; or very much improved on PGIC (substantial benefit). We calculated risk ratio (RR) and number needed to treat for an additional beneficial (NNTB) or harmful outcome (NNTH). We assessed the quality of the evidence using GRADE.
MAIN RESULTS
We included 45 studies lasting 2 to 16 weeks, with 11,906 participants - 68% from 31 new studies. Oral pregabalin doses of 150 mg, 300 mg, and 600 mg daily were compared with placebo. Postherpetic neuralgia, painful diabetic neuropathy, and mixed neuropathic pain predominated (85% of participants). High risk of bias was due mainly to small study size (nine studies), but many studies had unclear risk of bias, mainly due to incomplete outcome data, size, and allocation concealment.Postherpetic neuralgia: More participants had at least 30% pain intensity reduction with pregabalin 300 mg than with placebo (50% vs 25%; RR 2.1 (95% confidence interval (CI) 1.6 to 2.6); NNTB 3.9 (3.0 to 5.6); 3 studies, 589 participants, moderate-quality evidence), and more had at least 50% pain intensity reduction (32% vs 13%; RR 2.5 (95% CI 1.9 to 3.4); NNTB 5.3 (3.9 to 8.1); 4 studies, 713 participants, moderate-quality evidence). More participants had at least 30% pain intensity reduction with pregabalin 600 mg than with placebo (62% vs 24%; RR 2.5 (95% CI 2.0 to 3.2); NNTB 2.7 (2.2 to 3.7); 3 studies, 537 participants, moderate-quality evidence), and more had at least 50% pain intensity reduction (41% vs 15%; RR 2.7 (95% CI 2.0 to 3.5); NNTB 3.9 (3.1 to 5.5); 4 studies, 732 participants, moderate-quality evidence). Somnolence and dizziness were more common with pregabalin than with placebo (moderate-quality evidence): somnolence 300 mg 16% versus 5.5%, 600 mg 25% versus 5.8%; dizziness 300 mg 29% versus 8.1%, 600 mg 35% versus 8.8%.Painful diabetic neuropathy: More participants had at least 30% pain intensity reduction with pregabalin 300 mg than with placebo (47% vs 42%; RR 1.1 (95% CI 1.01 to 1.2); NNTB 22 (12 to 200); 8 studies, 2320 participants, moderate-quality evidence), more had at least 50% pain intensity reduction (31% vs 24%; RR 1.3 (95% CI 1.2 to 1.5); NNTB 22 (12 to 200); 11 studies, 2931 participants, moderate-quality evidence), and more had PGIC much or very much improved (51% vs 30%; RR 1.8 (95% CI 1.5 to 2.0); NNTB 4.9 (3.8 to 6.9); 5 studies, 1050 participants, moderate-quality evidence). More participants had at least 30% pain intensity reduction with pregabalin 600 mg than with placebo (63% vs 52%; RR 1.2 (95% CI 1.04 to 1.4); NNTB 9.6 (5.5 to 41); 2 studies, 611 participants, low-quality evidence), and more had at least 50% pain intensity reduction (41% vs 28%; RR 1.4 (95% CI 1.2 to 1.7); NNTB 7.8 (5.4 to 14); 5 studies, 1015 participants, low-quality evidence). Somnolence and dizziness were more common with pregabalin than with placebo (moderate-quality evidence): somnolence 300 mg 11% versus 3.1%, 600 mg 15% versus 4.5%; dizziness 300 mg 13% versus 3.8%, 600 mg 22% versus 4.4%.Mixed or unclassified post-traumatic neuropathic pain: More participants had at least 30% pain intensity reduction with pregabalin 600 mg than with placebo (48% vs 36%; RR 1.2 (1.1 to 1.4); NNTB 8.2 (5.7 to 15); 4 studies, 1367 participants, low-quality evidence), and more had at least 50% pain intensity reduction (34% vs 20%; RR 1.5 (1.2 to 1.9); NNTB 7.2 (5.4 to 11); 4 studies, 1367 participants, moderate-quality evidence). Somnolence (12% vs 3.9%) and dizziness (23% vs 6.2%) were more common with pregabalin.Central neuropathic pain: More participants had at least 30% pain intensity reduction with pregabalin 600 mg than with placebo (44% vs 28%; RR 1.6 (1.3 to 2.0); NNTB 5.9 (4.1 to 11); 3 studies, 562 participants, low-quality evidence) and at least 50% pain intensity reduction (26% vs 15%; RR 1.7 (1.2 to 2.3); NNTB 9.8 (6.0 to 28); 3 studies, 562 participants, low-quality evidence). Somnolence (32% vs 11%) and dizziness (23% vs 8.6%) were more common with pregabalin.Other neuropathic pain conditions: Studies show no evidence of benefit for 600 mg pregabalin in HIV neuropathy (2 studies, 674 participants, moderate-quality evidence) and limited evidence of benefit in neuropathic back pain or sciatica, neuropathic cancer pain, or polyneuropathy.Serious adverse events, all conditions: Serious adverse events were no more common with placebo than with pregabalin 300 mg (3.1% vs 2.6%; RR 1.2 (95% CI 0.8 to 1.7); 17 studies, 4112 participants, high-quality evidence) or pregabalin 600 mg (3.4% vs 3.4%; RR 1.1 (95% CI 0.8 to 1.5); 16 studies, 3995 participants, high-quality evidence).
AUTHORS' CONCLUSIONS
Evidence shows efficacy of pregabalin in postherpetic neuralgia, painful diabetic neuralgia, and mixed or unclassified post-traumatic neuropathic pain, and absence of efficacy in HIV neuropathy; evidence of efficacy in central neuropathic pain is inadequate. Some people will derive substantial benefit with pregabalin; more will have moderate benefit, but many will have no benefit or will discontinue treatment. There were no substantial changes since the 2009 review.

Meta-Analysis
BACKGROUND
Obstructive sleep apnoea (OSA) is a syndrome characterised by episodes of apnoea (complete cessation of breathing) or hypopnoea (insufficient breathing) during sleep. Classical symptoms of the disease - such as snoring, unsatisfactory rest and daytime sleepiness - are experienced mainly by men; women report more unspecific symptoms such as low energy or fatigue, tiredness, initial insomnia and morning headaches. OSA is associated with an increased risk of occupational injuries, metabolic diseases, cardiovascular diseases, mortality, and being involved in traffic accidents. Continuous positive airway pressure (CPAP) - delivered by a machine which uses a hose and mask or nosepiece to deliver constant and steady air pressure- is considered the first treatment option for most people with OSA. However, adherence to treatment is often suboptimal. Myofunctional therapy could be an alternative for many patients. Myofunctional therapy consists of combinations of oropharyngeal exercises - i.e. mouth and throat exercises. These combinations typically include both isotonic and isometric exercises involving several muscles and areas of the mouth, pharynx and upper respiratory tract, to work on functions such as speaking, breathing, blowing, sucking, chewing and swallowing.
OBJECTIVES
To evaluate the benefits and harms of myofunctional therapy (oropharyngeal exercises) for the treatment of obstructive sleep apnoea.
SEARCH METHODS
We identified randomised controlled trials (RCTs) from the Cochrane Airways Trials Register (date of last search 1 May 2020). We found other trials at web-based clinical trials registers.
SELECTION CRITERIA
We included RCTs that recruited adults and children with a diagnosis of OSA.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. We assessed our confidence in the evidence by using GRADE recommendations. Primary outcomes were daytime sleepiness, morbidity and mortality.
MAIN RESULTS
We found nine studies eligible for inclusion in this review and nine ongoing studies. The nine included RCTs analysed a total of 347 participants, 69 of them women and 13 children. The adults' mean ages ranged from 46 to 51, daytime sleepiness scores from eight to 14, and severity of the condition from mild to severe OSA. The studies' duration ranged from two to four months. None of the studies assessed accidents, cardiovascular diseases or mortality outcomes. We sought data about adverse events, but none of the included studies reported these. In adults, compared to sham therapy, myofunctional therapy: probably reduces daytime sleepiness (Epworth Sleepiness Scale (ESS), MD (mean difference) -4.52 points, 95% Confidence Interval (CI) -6.67 to -2.36; two studies, 82 participants; moderate-certainty evidence); may increase sleep quality (MD -3.90 points, 95% CI -6.31 to -1.49; one study, 31 participants; low-certainty evidence); may result in a large reduction in Apnoea-Hypopnoea Index (AHI, MD -13.20 points, 95% CI -18.48 to -7.93; two studies, 82 participants; low-certainty evidence); may have little to no effect in reduction of snoring frequency but the evidence is very uncertain (Standardised Mean Difference (SMD) -0.53 points, 95% CI -1.03 to -0.03; two studies, 67 participants; very low-certainty evidence); and probably reduces subjective snoring intensity slightly (MD -1.9 points, 95% CI -3.69 to -0.11 one study, 51 participants; moderate-certainty evidence). Compared to waiting list, myofunctional therapy may: reduce daytime sleepiness (ESS, change from baseline MD -3.00 points, 95% CI -5.47 to -0.53; one study, 25 participants; low-certainty evidence); result in little to no difference in sleep quality (MD -0.70 points, 95% CI -2.01 to 0.61; one study, 25 participants; low-certainty evidence); and reduce AHI (MD -6.20 points, 95% CI -11.94 to -0.46; one study, 25 participants; low-certainty evidence). Compared to CPAP, myofunctional therapy may result in little to no difference in daytime sleepiness (MD 0.30 points, 95% CI -1.65 to 2.25; one study, 54 participants; low-certainty evidence); and may increase AHI (MD 9.60 points, 95% CI 2.46 to 16.74; one study, 54 participants; low-certainty evidence). Compared to CPAP plus myofunctional therapy, myofunctional therapy alone may result in little to no difference in daytime sleepiness (MD 0.20 points, 95% CI -2.56 to 2.96; one study, 49 participants; low-certainty evidence) and may increase AHI (MD 10.50 points, 95% CI 3.43 to 17.57; one study, 49 participants; low-certainty evidence). Compared to respiratory exercises plus nasal dilator strip, myofunctional therapy may result in little to no difference in daytime sleepiness (MD 0.20 points, 95% CI -2.46 to 2.86; one study, 58 participants; low-certainty evidence); probably increases sleep quality slightly (-1.94 points, 95% CI -3.17 to -0.72; two studies, 97 participants; moderate-certainty evidence); and may result in little to no difference in AHI (MD -3.80 points, 95% CI -9.05 to 1.45; one study, 58 participants; low-certainty evidence). Compared to standard medical treatment, myofunctional therapy may reduce daytime sleepiness (MD -6.40 points, 95% CI -9.82 to -2.98; one study, 26 participants; low-certainty evidence) and may increase sleep quality (MD -3.10 points, 95% CI -5.12 to -1.08; one study, 26 participants; low-certainty evidence). In children, compared to nasal washing alone, myofunctional therapy and nasal washing may result in little to no difference in AHI (MD 3.00, 95% CI -0.26 to 6.26; one study, 13 participants; low-certainty evidence).
AUTHORS' CONCLUSIONS
Compared to sham therapy, myofunctional therapy probably reduces daytime sleepiness and may increase sleep quality in the short term. The certainty of the evidence for all comparisons ranges from moderate to very low, mainly due to lack of blinding of the assessors of subjective outcomes, incomplete outcome data and imprecision. More studies are needed. In future studies, outcome assessors should be blinded. New trials should recruit more participants, including more women and children, and have longer treatment and follow-up periods.

Review
BACKGROUND
Although combination formulas containing antihistamines, decongestants, and/or analgesics are sold over-the-counter in large quantities for the common cold, the evidence for their effectiveness is limited. This is an update of a review first published in 2012.
OBJECTIVES
To assess the effectiveness of antihistamine-decongestant-analgesic combinations compared with placebo or other active controls (excluding antibiotics) in reducing the duration of symptoms and alleviating symptoms (general feeling of illness, nasal congestion, rhinorrhoea, sneezing, and cough) in children and adults with the common cold.
SEARCH METHODS
We searched CENTRAL, MEDLINE via EBSCOhost, Embase, CINAHL via EBSCOhost, LILACS, and Web of Science to 10 June 2021. We searched the WHO ICTRP and ClinicalTrials.gov on 10 June 2021.
SELECTION CRITERIA
Randomised controlled trials investigating the effectiveness of antihistamine-decongestant-analgesic combinations compared with placebo, other active treatment (excluding antibiotics), or no treatment in children and adults with the common cold.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. We assessed the certainty of the evidence using the GRADE approach. We categorised the included trials according to the active ingredients.
MAIN RESULTS
We identified 30 studies (6304 participants) including 31 treatment comparisons. The control intervention was placebo in 26 trials and an active substance (paracetamol, chlorphenindione + phenylpropanolamine + belladonna, diphenhydramine) in six trials (two trials had placebo as well as active treatment arms). Reporting of methods was generally poor, and there were large differences in study design, participants, interventions, and outcomes. Most of the included trials involved adult participants. Children were included in nine trials. Three trials included very young children (from six months to five years), and five trials included children aged 2 to 16. One trial included adults and children aged 12 years or older. The trials took place in different settings: university clinics, paediatric departments, family medicine departments, and general practice surgeries. Antihistamine-decongestant: 14 trials (1298 participants). Eight trials reported on global effectiveness, of which six studies were pooled (281 participants on active treatment and 284 participants on placebo). The odds ratio (OR) of treatment failure was 0.31 (95% confidence interval (CI) 0.20 to 0.48; moderate certainty evidence); number needed to treat for an additional beneficial outcome (NNTB) 3.9 (95% CI 3.03 to 5.2). On the final evaluation day (follow-up: 3 to 10 days), 55% of participants in the placebo group had a favourable response compared to 70% on active treatment. Of the two trials not pooled, one showed some global effect, whilst the other showed no effect. Adverse effects: the antihistamine-decongestant group experienced more adverse effects than the control group: 128/419 (31%) versus 100/423 (13%) participants suffered one or more adverse effects (OR 1.58, 95%CI 0.78 to 3.21; moderate certainty of evidence). Antihistamine-analgesic: four trials (1608 participants). Two trials reported on global effectiveness; data from one trial were presented (290 participants on active treatment and 292 participants on ascorbic acid). The OR of treatment failure was 0.33 (95% CI 0.23 to 0.46; moderate certainty evidence); NNTB 6.67 (95% CI 4.76 to 12.5). Forty-three per cent of participants in the control group and 70% in the active treatment group were cured after six days of treatment. The second trial also showed an effect in favour of the active treatment. Adverse effects: there were not significantly more adverse effects in the active treatment group compared to placebo (drowsiness, hypersomnia, sleepiness 10/152 versus 4/120; OR 1.64 (95 % CI 0.48 to 5.59; low certainty evidence). Analgesic-decongestant: seven trials (2575 participants). One trial reported on global effectiveness: 73% of participants in the analgesic-decongestant group reported a benefit compared with 52% in the control group (paracetamol) (OR of treatment failure 0.28, 95% CI 0.15 to 0.52; moderate certainty evidence; NNTB 4.7). Adverse effects: the decongestant-analgesic group experienced significantly more adverse effects than the control group (199/1122 versus 75/675; OR 1.62 95% CI 1.18 to 2.23; high certainty evidence; number needed to treat for an additional harmful outcome (NNTH 17). Antihistamine-analgesic-decongestant: six trials (1014 participants). Five trials reported on global effectiveness, of which two studies in adults could be pooled: global effect reported with active treatment (52%) and placebo (34%) was equivalent to a difference of less than one point on a four- or five-point scale; the OR of treatment failure was 0.47 (95% CI 0.33 to 0.67; low certainty evidence); NNTB 5.6 (95% CI 3.8 to 10.2). One trial in children aged 2 to 12 years, and two trials in adults found no beneficial effect. Adverse effects: in one trial 5/224 (2%) suffered adverse effects with the active treatment versus 9/208 (4%) with placebo. Two other trials reported no differences between treatment groups.
AUTHORS' CONCLUSIONS
We found a lack of data on the effectiveness of antihistamine-analgesic-decongestant combinations for the common cold. Based on these scarce data, the effect on individual symptoms is probably too small to be clinically relevant. The current evidence suggests that antihistamine-analgesic-decongestant combinations have some general benefit in adults and older children. These benefits must be weighed against the risk of adverse effects. There is no evidence of effectiveness in young children. In 2005, the US Food and Drug Administration issued a warning about adverse effects associated with the use of over-the-counter nasal preparations containing phenylpropanolamine.

Review
Sleep disturbance is common in people with multiple sclerosis and may worsen fatigue; however, the assessment of sleep-fatigue relationships varies across studies. To better understand sleep-fatigue relationships in this population, we conducted a systematic review and random effects meta-analyses for the associations between fatigue and 10 sleep variables: Sleep-disordered breathing, daytime sleepiness, sleep quality, insomnia, restless legs, number of awakenings, sleep efficiency, sleep latency, sleep duration, and wake after sleep onset. Of the 1062 studies screened, 46 met inclusion criteria and provided sufficient data for calculating Hedges' g. Study quality was assessed using the Newcastle-Ottawa Scale. Sample characteristics did not differ between the 10 analyses. Results indicated that sleep quality and insomnia (assessed via self-report or diagnostic criteria) were strongly associated with fatigue (all s ≥ 0.80 and all < .001). In contrast, the number of awakenings and sleep duration (assessed objectively) were not significantly associated with fatigue. Remaining sleep variables yielded moderate, significant effects. Most effects did not vary based on study quality or sample demographics. Results highlight that insomnia and perceptions of poor sleep have a stronger link than objective sleep duration to fatigue in multiple sclerosis and may represent a more effective target for intervention.

Meta-Analysis
OBJECTIVE
The aim of the study was to summarize the findings of the studies documenting the efficacy and safety of perampanel when used in children/adolescents or adults, either as add-on therapy or as monotherapy.
MATERIALS AND METHODS
A systematic search was conducted using PubMed, EMBASE and Scopus. Only studies with a cohort-based approach (either prospective or retrospective) were included. We were interested in real-world studies and therefore, studies with a highly regulated environment, such as randomized controlled trials, were excluded. The primary outcomes of interest were retention rates, response rates and seizure-free rates. Random effects model was used for the analysis. Effect sizes were reported as pooled prevalence along with 95% confidence intervals.
RESULTS
A total of 34 studies were included. The retention rates, within 24 months from initiation of treatment as an add-on therapy, ranged between 65% to 77% among children and adolescents. For adults, the retention rate varied between 56 to 77% within 24 months from initiation of treatment. The response rate was around 70% in children/adolescents and 52% in adults at 24 months of follow-up. Around 25% of children and adolescents and 37% of adults were seizure-free at 24 months follow-up period. The proportion of children/adolescents and adults reporting any treatment-related adverse effects was 29% and 41%, respectively. The commonly reported adverse effects were dizziness/drowsiness, somnolence, behavioral problems (irritability, aggression, anxiety, mood changes), postural instability/gait problems, fatigue and weight gain.
CONCLUSIONS
Perampanel might be an effective anti-epileptic drug in both children/adolescents and adults when used as an adjunct therapy. More data is required to comment on its use as monotherapy. Careful monitoring for psychiatric problems and behavioral disturbances is required, both prior to initiating treatment as well as during the course of management. Studies with long-term follow-up may are needed to confirm the findings of this meta-analysis.

Meta-Analysis
Drowsiness and distraction are major factors of road crashes and responsible of>35% of road fatalities. Automated driving could solve or minimize their impact, yet it is also in itself a way to promote them. Previous literature reviews and meta-analysis regarding take-overs during automated driving primarily focused on distraction rather than drowsiness. We thus present a systematic and meta-analysis literature review focused on the effect of distraction and drowsiness on take-over performance. From an initial selection of 1896 articles from databases, we obtained by applying systematic review methodology a total of 58 articles with 42 articles dedicated to distraction and 17 articles related to drowsiness. According to our analysis, we demonstrated that distraction and drowsiness increased the take-over request reaction time (TOR-RT), which could also lead to a reduction of the quality of take-overs. In addition, this longer reaction time was even more important in the case of handheld non-driving related tasks, which is important to consider as phone use is among the most frequent tasks done during automated driving. On a more methodological aspect, we also demonstrated that take-over time budget had a significant effect on TOR-RT. However, it is difficult to estimate to what extend distraction and drowsiness could impact the take-over quality, even if several elements supported safety issues. We underpinned several limits of the current methodologies applied in the study of distraction and drowsiness such as (i) the lack of additional measures related to the take-over quality (e.g., accelerations, collision rate), (ii) the many different methodologies applied to the determination of the TOR-RT (e.g., deactivation by the steering wheel, pedals, button), (iii) the high frequency of take-over requests which can lead to habituation effects, (iv) the lack of control conditions, (v) the fact that the level of drowsiness was relatively low in most studies. We thus highlighted recommendations for a better estimation of the effect of distraction and drowsiness on take-over performance. Further studies should adopt more standardized measures of TOR-RT and additional take-over quality measures, try minimizing the number of take-over requests, and carefully consider the time budget available for the use case since it influences the TOR-RT. Regarding distraction, researchers should consider the impact of tasks requiring handholding items. Concerning drowsiness, further protocols should consider the non-linearity of drowsiness and presence of micro sleeps and favor take-over requests based on drowsiness level protocols rather than on fixed duration protocols.

BACKGROUND
Menstrual disturbances harm women's health, and general well-being. As growing evidence highlights the relationship between sleep and menstrual disturbances, it is imperative to comprehensively examine the association between sleep and menstrual disturbance considering the multiple dimensions of sleep. This systematic review aims to identify the association between sleep and menstrual disturbances by evaluating using Buysse's sleep health framework.
METHODS
A comprehensive search of the literature was conducted in PubMed, EMBASE, psychINFO, and CINAHL to identify publications describing any types of menstrual disturbances, and their associations with sleep published between January 1, 1988 to June 2, 2022. Quality assessment was conducted using the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies. The findings were iteratively evaluated menstrual disturbances and their association with sleep using Buysse's sleep health framework. This framework understands sleep as multidimensional concept and provides a holistic framing of sleep including Satisfaction, Alertness during waking hours, Timing of sleep, Efficiency, and Sleep duration. Menstrual disturbances were grouped into three categories: premenstrual syndrome, dysmenorrhea, and abnormal menstrual cycle/heavy bleeding during periods.
RESULTS
Thirty-five studies were reviewed to examine the association between sleep and menstrual disturbances. Premenstrual syndrome and dysmenorrhea were associated with sleep disturbances in sleep health domains of Satisfaction (e.g., poor sleep quality), Alertness during waking hours (e.g., daytime sleepiness), Efficiency (e.g., difficulty initiating/maintaining sleep), and Duration (e.g., short sleep duration). Abnormal menstrual cycle and heavy bleeding during the period were related to Satisfaction, Efficiency, and Duration. There were no studies which investigated the timing of sleep.
CONCLUSIONS/IMPLICATIONS
Sleep disturbances within most dimensions of the sleep health framework negatively impact on menstrual disturbances. Future research should longitudinally examine the effects of sleep disturbances in all dimensions of sleep health with the additional objective sleep measure on menstrual disturbances. This review gives insight in that it can be recommended to provide interventions for improving sleep disturbances in women with menstrual disturbance.

Review
Driving a vehicle is a complex, multidimensional, and potentially risky activity demanding full mobilization and utilization of physiological and cognitive abilities. Drowsiness, often caused by stress, fatigue, and illness declines cognitive capabilities that affect drivers' capability and cause many accidents. Drowsiness-related road accidents are associated with trauma, physical injuries, and fatalities, and often accompany economic loss. Drowsy-related crashes are most common in young people and night shift workers. Real-time and accurate driver drowsiness detection is necessary to bring down the drowsy driving accident rate. Many researchers endeavored for systems to detect drowsiness using different features related to vehicles, and drivers' behavior, as well as, physiological measures. Keeping in view the rising trend in the use of physiological measures, this study presents a comprehensive and systematic review of the recent techniques to detect driver drowsiness using physiological signals. Different sensors augmented with machine learning are utilized which subsequently yield better results. These techniques are analyzed with respect to several aspects such as data collection sensor, environment consideration like controlled or dynamic, experimental set up like real traffic or driving simulators, etc. Similarly, by investigating the type of sensors involved in experiments, this study discusses the advantages and disadvantages of existing studies and points out the research gaps. Perceptions and conceptions are made to provide future research directions for drowsiness detection techniques based on physiological signals.
