Review
Narcolepsy is a chronic and disabling neurological disorder characterized by excessive daytime sleepiness (EDS) and cataplexy. Historically, some medications have demonstrated efficacy in managing EDS and cataplexy symptoms. However, some patients cannot tolerate them, become refractory, or may use concomitant medications that preclude the use due to drug-drug interaction. Therefore, there is a necessity to explore the efficacy of new treatments, such as solriamfetol (JZP-110), a 2019 FDA-approved drug indicated to improve wakefulness in adults with EDS associated with narcolepsy. We conducted this systematic review to investigate the effectiveness of solriamfetol in EDS and cataplexy, and the drug's overall safety. For this study, we used the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and MOOSE protocol. After an initial search of 119 papers, we included four clinical trials to investigate and analyze the use of solriamfetol for the treatment of narcolepsy. Solriamfetol was proven to improve objective measures of EDS in all clinical trials. We conducted this systematic review using objective measures such as the Epworth Sleepiness Scale and the Maintenance of Wakefulness Test. Overall, cataplexy was not formally evaluated in the four clinical trials; however, it demonstrated that EDS improved in patients with and without cataplexy. More clinical trials are needed to analyze the efficacy of solriamfetol on cataplexy. The effect of solriamfetol in EDS seems to be conclusive.

Chronic inflammatory skin disorders are known to affect sleep quality; however, the relationship between hidradenitis suppurativa (HS) and sleep is not well understood. We performed a systematic review of HS and sleep disorders and sleep quality in HS patients. We identified seven studies comprising 343,870 subjects. We found that HS patients have a higher likelihood of having a sleep disorder such as obstructive sleep apnea, as well as other non-sleep apnea. Several studies showed that patients reported worse sleep quality due to symptoms of HS such as pruritus and pain. HS patients may be at risk for additional cardiovascular comorbidities and poorer quality of life secondary to these sleep disorders and poor sleep quality. Further high-quality research evaluating these associations is warranted.

PURPOSE
Humans show near-24-h physiological and behavioral rhythms, which encompass the daily cycle of sleep and wakefulness. Exercise stimulates circadian rhythms, including those of cortisol, melatonin, and core body temperature, and affects sleep quality. We systematically reviewed studies that examined the effects of exercise intensity and timing on physiological circadian rhythms and sleep quality.
METHODS
In this systematic review, we used the online databases PubMed, Science Direct, Web of Science, and Embase. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Two independent and experienced systematic reviewers performed the search and selected relevant studies. The participant, intervention, comparison, and outcome characteristics were: (1) adults; (2) exercise treatment; (3) no exercise treatment or different types of exercise (pre-exercise baseline); (4) cortisol, melatonin, or core body temperature measurement, and subjective or objective sleep quality assessments.
RESULTS
We identified 9 relevant articles involving 201 participants (77.1% of whom were male). Our review revealed that short-term evening exercise delayed melatonin rhythm and increased nocturnal core body temperature; however, no negative effects on non-rapid eye movement sleep and sleep efficiency were observed. Moreover, no differences in sleep quality were observed between acute high-intensity and moderate-intensity exercises. With long exercise durations, the core body temperature tended to increase and return to baseline levels at 30-120 min.
CONCLUSION
Our review showed that short-term evening exercise and high-intensity exercise did not have a significant negative effect on sleep quality but physiological circadian rhythm tended to alter. Longterm morning exercise tended to decrease cortisol concentrations after awakening and improve sleep quality. Future studies should examine the effects of long-term exercise timing and intensity on circadian rhythm and sleep.

Meta-Analysis
BACKGROUND
Chronic cluster headache (CCH) is a severe and debilitating sub-type of trigeminal autonomic cephalalgia that can be resistant to medical management and associated with significant impairment in quality of life. Studies of deep brain stimulation (DBS) for CCH have provided promising results but have not been assessed in a comprehensive systematic review/meta-analysis.
OBJECTIVE
The objective was to perform a systematic literature review and meta-analysis of patients with CCH treated with DBS to provide insight on safety and efficacy.
METHODS
A systematic review and meta-analysis were performed according to PRISMA 2020 guidelines. 16 studies were included in final analysis. A random-effects model was used to meta-analyze data.
RESULTS
Sixteen studies reported 108 cases for data extraction and analysis. DBS was feasible in >99% of cases and was performed either awake or asleep. Meta-analysis revealed that the mean difference in headache attack frequency and headache intensity after DBS were statistically significant (p < 0.0001). Utilization of microelectrode recording was associated with statistically significant improvement in headache intensity postoperatively (p = 0.006). The average overall follow-up period was 45.4 months and ranged from 1 to 144 months. Death occurred in <1%. The rate of major complications was 16.67%.
CONCLUSIONS
DBS for CCHs is a feasible surgical technique with a reasonable safety profile that can be successfully performed either awake or asleep. In carefully selected patients, approximately 70% of patients achieve excellent control of their headaches.

Journal of Consulting and Clinical... May 2023This systematic review and meta-analysis summarize current knowledge on emotional change processes and mechanisms and their relationship with outcomes in psychotherapy.
OBJECTIVE
This systematic review and meta-analysis summarize current knowledge on emotional change processes and mechanisms and their relationship with outcomes in psychotherapy.
METHOD
We reviewed the main change processes and mechanisms in the literature and conducted meta-analyses of process/mechanism-outcome associations whenever methodologically feasible.
RESULTS
A total of 121 studies, based on 92 unique samples, met criteria for inclusion. Of these, 85 studies could be subjected to meta-analysis. The emotional change processes and mechanisms most robustly related to improvement were fear habituation across sessions in exposure-based treatment of anxiety disorders ( = .38), experiencing in psychotherapy for depression ( = .44), and emotion regulation in psychotherapies for patients with various anxiety disorders ( = .37). Common methodological problems were that studies often did not ascertain representative estimates of the processes under investigation, determine if changes in processes and mechanisms temporally preceded outcomes, disentangle effects at the within- and between-client levels, or assess contributions of therapists and clients to a given process.
CONCLUSIONS
The present study has identified a number of emotional processes and mechanisms associated with outcome in psychotherapy, most notably fear habituation, emotion regulation, and experiencing. A common denominator between these appears to be the habitual reorganization of maladaptive emotional perception. We view this as a central pan-theoretical change mechanism, the essence of which appears to be increased differentiation between external triggers and one's own affective responses, which facilitates tolerance for affective arousals and leads to improved capacity for adaptive meaning-making in emotion-eliciting situations.

Review
Social cognitive abilities are affected by preterm birth, but pathways to, and risk factors for this outcome are not well mapped. We examined direct assessment tasks including objective coding of parent-child play to chart social development in infancy and pre-school years. A systematic search and data-extraction procedure yielded seventy-nine studies (4930 preterm and 2109 term children, aged birth - five years), for inclusion. We detected a pattern of reduced social attention in the first 12 months of life with evidence of reduced performance in social cognitive tasks later in the preschool years. However, we did not identify a consistent, distinctive preterm social phenotype in early life. Instead, the interactive behaviour of preterm infants reflects factors from outside the social cognitive domain, such as attention, language, and socioeconomic status. By combining data across samples and measures we revealed the role of domain-general skills, which may in future prove fruitful intervention targets.

Review
PURPOSE
Adverse effects of selective serotonin reuptake inhibitors (SSRIs) on sexual function have been an important area of research for many years. However, the duration of SSRI-associated sexual adverse effects, and their possible persistence after treatment discontinuation, is still uncertain. The aims of the current systematic review were first to identify existing evidence of sexual dysfunction following SSRI discontinuation, and to provide an account of reported symptoms and proposed treatment options; and second, to establish whether current literature allows accurate estimates of the prevalence of such sexual dysfunction.
METHODS
A systematic review was conducted on PubMed, Embase, and Google Scholar; papers with clinical data regarding patients with persistent sexual dysfunction after SSRI treatment suspension were included.
RESULTS
Overall, two retrospective interventional studies, six observational studies and 11 case reports were judged eligible for inclusion. It was not possible to determine reliable estimates of prevalence. Similarly, a cause-effect relationship between SSRI exposure and persistent sexual impairment could not be ascertained. Nonetheless, the potential for continued sexual disturbances despite discontinuation could not be entirely ruled out.
CONCLUSIONS
There is a need to investigate a possible dose-response relationship between SSRI exposure and persistent sexual adverse effects. Treatment options for persistent dysfunctions remain limited, but novel therapeutic approaches may be required in order to address an otherwise neglected need for sexual well-being.

Meta-Analysis
In a largely sleep-deprived society, quantifying the effects of sleep loss on emotion is critical for promoting psychological health. This preregistered systematic review and meta-analysis quantified the effects of various forms of sleep loss on multiple aspects of emotional experiences. Eligible studies used experimental reductions of sleep via total sleep deprivation, partial sleep restriction, or sleep fragmentation in healthy populations to examine effects on positive affect, negative affect, general mood disturbances, emotional reactivity, anxiety symptoms, and/or depressive symptoms. In total, 1,338 effect sizes across 154 studies were included ( = 5,717; participant age range = 7-79 years). Random effects models were conducted, and all forms of sleep loss resulted in reduced positive affect (standardized mean difference [SMD] = -0.27 to -1.14), increased anxiety symptoms (SMD = 0.57-0.63), and blunted arousal in response to emotional stimuli (SMD = -0.20 to -0.53). Findings for negative affect, reports of emotional valence in response to emotional stimuli, and depressive symptoms were mixed and depended on the type of sleep loss. Nonlinear effects for the amount of sleep loss as well as differences based on the stage of sleep restricted (i.e., rapid eye movement sleep or slow-wave sleep) were also detected. This study represents the most comprehensive quantitative synthesis of experimental sleep and emotion research to date and provides strong evidence that periods of extended wakefulness, shortened sleep duration, and/or nighttime awakenings adversely influence human emotional functioning. Findings provide an integrative foundation for future research on sleep and emotion and elucidate the precise ways that inadequate sleep may impact our daytime emotional lives.

Meta-Analysis Review
Attentional bias to food stimuli may contribute to the etiology and/or maintenance of overweight and obesity. We conducted a literature review and meta-analysis per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify the effect size associated with attentional bias to palatable food in persons with overweight/obesity across the age spectrum. Included studies measured attentional bias to food stimuli using two reaction-time tasks (dot-probe, emotional Stroop), eye-tracking methodology, and/or event-related potentials. Meta-analysis showed that persons with overweight/obesity did not differ from persons with a healthy weight on any of the following: automatic and maintained attention to food stimuli measured by the dot-probe task (Hedge's g = -0.355, 95% CI = -0.383, 0.486; and Hedge's g = 0.006, 95% CI = -0.187, 0.199); attentional bias to food stimuli measured by the emotional Stroop task (Hedge's g = 0.184, 95% CI = -0.283, 0.651); and attentional bias to food images on gaze-direction and gaze-duration bias eye-tracking metrics (Hedge's g = 0.317, 95% CI = -0.096, 0.729; and Hedge's g = 0.056, 95% CI = -0.296, 0.407). Systematic review of preliminary event-related potentials research suggested automatic, but not maintained, attention to food images in persons with overweight/obesity. Limitations of past attentional bias research in overweight/obesity, such as poor reliability of measures and lack of consideration of moderators, such as binge eating and degree of overweight/obesity, preclude the ability to draw firm conclusions. We recommend implementation of empirically based methods for improving psychometric properties of attentional bias measures and examination of potential moderators so that the field can understand whether attentional bias to food is truly greater in overweight/obesity.

Meta-Analysis Review
The efficacy of bariatric surgery on pulmonary function and sleep architecture of patients with obstructive sleep apnea and co-morbid obesity: a systematic review and meta-analysis.
Obstructive sleep apnea (OSA) is highly prevalent in patients with morbid obesity. There is a growing interest in the role of bariatric surgery in OSA management. This study aims to evaluate the therapeutic efficacy of bariatric surgery on changes in pulmonary function and sleep architecture. Studies of patients with OSA that underwent bariatric surgery were searched in 4 different databases (PubMed, Cochrane, Web of Science, and Embase) until October 31, 2022. We identified studies evaluating the efficacy of surgical intervention on primary outcomes (body mass index [BMI] and apnea-hypopnea index [AHI]) and secondary outcomes such as forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), FEV1/FVC, oxygen desaturation index (ODI), T90, mean oxygen saturation (SpO), nadirSpO, sleep efficiency (SE), N1%, N2%, N3%, rapid eye movement (REM%), arousal index, Epworth sleepiness scale (ESS), neck circumference, waist circumference, and weight. A total of 24 eligible studies were finally chosen. Risk of bias assessed through funnel plots was collected and analyzed via random effects meta-analyses. There were significant reductions in BMI and AHI after bariatric surgery induced weight loss. Accordingly, improvement in FVC, meanSpO, nadirSpO, SE, N3%, REM%, and ESS were observed compared with baseline. Patients with OSA also exhibit lower ODI, T90, arousal index, neck circumference, waist circumference, and weight after treatment. Bariatric surgery has beneficial effects on patients with OSA and obesity, particularly with morbid obesity. Surgical weight loss significantly eliminates apnea-hypopnea events, reduces weight, increases oxygen saturation, N3 and REM sleep stage, reduces sleep fragmentation, and improves pulmonary functions with augmented FVC.
