Global prevalence of poor sleep quality in cancer patients: A systematic review and meta-analysis. Gen Hosp Psychiatry 2024; 87:92-102. [PMID: 38382421 DOI: 10.1016/j.genhosppsych.2023.12.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 11/27/2023] [Accepted: 12/06/2023] [Indexed: 02/23/2024]
Abstract
OBJECTIVE Poor sleep quality is common in patients with cancer, but the prevalence rates varied widely across studies. This systematic review and meta-analysis examined the pooled prevalence of poor sleep quality among patients with cancer. METHODS Systematic literature searches were independently conducted in the major databases (Web of Science, PubMed, EMBASE and PsycINFO). Studies that reported the prevalence of poor sleep quality in patients with cancer were analyzed using a random effects model. Funnel plots and Egger's tests were used to assess publication bias. Statistical analyses were performed using R software. RESULTS A total of 59 epidemiological studies involving 16,223 patients were included. The pooled prevalence of poor sleep quality in patients with cancer was 57.4% [95% confidence interval (CI): 53.3% - 61.6%]. Additionally, three comparative studies with 372 patients and 412 healthy controls were included. Compared to healthy controls, patients with cancer had a significantly higher risk for poor sleep quality [odd ratio (OR) = 3.0; 95%CI: 1.2-7.2; P < 0.05]. Subgroup analyses of the studies revealed that studies from Middle East & North Africa region and low income countries, and on gynecological cancer as well as those with a lower cut-off value of sleep quality (all P < 0.01) reported a higher prevalence of poor sleep quality. Meta-regression analyses showed that higher prevalence of poor sleep quality was associated with higher prevalence of comorbid depression (P < 0.05) and anxiety (P < 0.01), but was associated with a lower education level (P < 0.05) and alcohol use ratio (P < 0.05). CONCLUSION Poor sleep quality is common among patients with cancer. Considering the overall high prevalence rate and negative impact of poor sleep quality, appropriate measures to identify and improve poor sleep quality are needed to enhance the clinical outcomes in this group.

Abstract
OBJECTIVE Poor sleep quality is common in patients with schizophrenia but estimated prevalence rates in this population have been mixed. This systematic review and meta-analysis examined the prevalence of poor sleep quality in schizophrenia samples and moderators of prevalence from epidemiological studies as well as the risk of poor sleep quality in schizophrenia patients based on case-control studies. METHODS Both international (PubMed, Web of Science, PsycINFO, EMBASE) and Chinese databases [Chinese Nation knowledge Infrastructure (CNKI) and WANFANG] were systematically searched. Studies that estimated the prevalence of poor sleep quality in schizophrenia were analyzed using a random effects model. Funnel plots and Egger's tests were used to assess publication bias. Statistical analyses were performed using R software. RESULTS In total, 23 epidemiological studies and nine case-control studies were included. Based on the epidemiological studies, the pooled overall prevalence of poor sleep quality was 63.4 % [95 % confidence interval (CI): 57.0 %-69.9 %]. Additionally, based on the nine case-control studies, schizophrenia patients had a significantly higher risk for poor sleep quality compared to healthy controls [odd ratio (OR) = 4.5; 95%CI: 2.4-8.3; P < 0.0001]. CONCLUSION Poor sleep quality is common among schizophrenia patients. Considering negative outcomes caused by poor sleep quality, regular screening on poor sleep quality should be conducted and effective interventions should be provided to those in need.

Abstract
The COVID-19 pandemic and the ensuing widespread lockdown measures have had a negative impact on the mental health of children and adolescents. We thus conducted a meta-analysis of the worldwide prevalence of sleep disturbances in children and adolescents during the COVID-19 pandemic. We performed a systematic literature search of the major international (PubMed, PsycINFO, Web of Science) and Chinese (Chinese Nation Knowledge Infrastructure (CNKI) and WANFANG) databases from their commencement dates to 27 December 2022. Altogether, 57 articles covering 206,601 participants were included in the meta-analysis. The overall prevalence of sleep disturbances was 34.0% (95% confidence interval (CI): 28-41%). The prevalence of parent-reported sleep disturbances during the COVID-19 pandemic was significantly higher than that of self-reported (p = 0.005) sleep disturbances. Epidemiological studies jointly conducted across Asia and Europe had a higher prevalence of sleep disturbances compared to those conducted in Asia, Europe, America, Oceania, or South America alone (p < 0.001). Children had a significantly higher prevalence of sleep disturbances compared to adolescents alone or a mixed cohort of children and adolescents (p = 0.022). Meta-regression analyses revealed that mean age (p < 0.001), quality evaluation score (p < 0.001), and percentage of men (p < 0.001) showed negative associations, while time of survey (B = 1.82, z = 34.02, p < 0.001) showed a positive association with the prevalence of sleep disturbances. Sleep disturbances were common in children and adolescents during the COVID-19 pandemic.

Prevalence and factors associated with restless legs syndrome among pregnant women in middle-income countries: a systematic review and meta-analysis. Front Med (Lausanne) 2023; 10:1326337. [PMID: 38188334 PMCID: PMC10771314 DOI: 10.3389/fmed.2023.1326337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 11/28/2023] [Indexed: 01/09/2024] Open
Abstract
Introduction Restless legs syndrome (RLS) is a debilitating condition characterized by uncomfortable sensations in the legs, typically occurring during periods of rest or sleep. It is more prevalent during pregnancy and is linked to sleep disturbances, diminished quality of life, and pregnancy complications. However, previous studies yielded inconsistent findings among pregnant women in middle-income countries. Consequently, this systematic review and meta-analysis sought to determine the pooled prevalence of restless legs syndrome and its associated factors in these populations. Method A systematic review and meta-analysis was conducted on published studies from middle-income countries until May 2023. The review strictly adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant search terms were used to search for studies in PubMed, MEDLINE, EMBASE, and Google Scholar. Data extraction was performed using the Joanna Briggs Institute tool for prevalence studies. The meta-analysis was conducted using STATA 17 software, and heterogeneity was assessed using the I2 test, while publication bias was evaluated using Egger's test. Forest plots were also used to present the pooled prevalence and odds ratio (OR) with a 95% confidence interval (CI) using the random-effects model. Result This review included 22 studies from nine countries with a total of 17, 580 study participants. The overall pooled prevalence of RLS among pregnant women in middle-income countries was 13.82% (95% CI: 13.31, 14.32), and having low hemoglobin level (AOR: 1.68, 95% CI: 1.29, 2.18), history of RLS (AOR: 7.54, 95% CI: 3.02, 18.79), muscle cramps (AOR: 3.58, 95% CI: 1.21, 10.61), excessive day time sleepiness (AOR: 4.02, 95% CI: 1.34, 12.04), preeclampsia (AOR: 2.06, 95% CI: 1.28, 3.30), and taking prophylactic iron supplementation (AOR: 0.59, 95% CI: 0.50, 0.69) were the identified factors associated with it. Conclusion Generally, nearly one in every eight pregnant women in middle-income countries develop restless legs syndrome during pregnancy. Having low hemoglobin level, a history of RLS, muscle cramps, excessive daytime sleepiness, preeclampsia, and taking prophylactic iron supplementation were the identified factors associated with it. These findings underscore the importance of addressing the identified factors associated with RLS in order to effectively mitigate its occurrence among pregnant women.

Abstract
OBJECTIVE Restless legs syndrome (RLS) has serious effects on patients' sleep quality, physical and mental health. However, the pathophysiological mechanisms of RLS remain unclear. This study utilized both static and dynamic functional activity and connectivity analyses approaches as well as effective connectivity analysis to reveal the neurophysiological basis of RLS. METHODS The resting-state functional MRI (rs-fMRI) data from 32 patients with RLS and 33 age-, and gender-matched healthy control (HC) were collected. Dynamic and static amplitude of low frequency fluctuation (ALFF), functional connectivity (FC), and Granger causality analysis (GCA) were employed to reveal the abnormal functional activities and couplings in patients with RLS. RESULTS RLS patients showed over-activities in left parahippocampus and right cerebellum, hyper-connectivities of right cerebellum with left basal ganglia, left postcentral gyrus and right precentral gyrus, and enhanced effective connectivity from right cerebellum to left postcentral gyrus compared to HC. CONCLUSIONS Abnormal cerebellum-basal ganglia-sensorimotor cortex circuit may be the underlying neuropathological basis of RLS. Our findings highlight the important role of right cerebellum in the onset of RLS and suggest right cerebellum may be a potential target for precision therapy.

Abstract
OBJECTIVES The current study aimed to search the prevalence and severity of restless legs syndrome (RLS) in pregnancy according to the three trimesters and predictive factors of RLS in pregnancy based on validated diagnostic tools and a thorough literature review. METHODS The cross-sectional descriptive study included 500 pregnant women without comorbidities who were interviewed face-to-face. Age, height, weight, week of pregnancy, smoking, alcohol, caffeine use, regular exercise, and lab test results from the last visit were all included in the data. Only women satisfying the RLS diagnostic criteria were given the Restless Legs Syndrome Rating Scale. RESULTS The prevalence of RLS was found to be 29.2% with the highest rate in the third trimester (64.4%). In all trimesters, low ferritin (first trimester: p = 0.004; second trimester: p < 0.001; third trimester: p < 0.001), folic acid (first trimester: p = 0.001; second trimester: p < 0.001; third trimester: p < 0.001), vitamin B12 (first trimester: p = 0.003; second trimester: p < 0.001; third trimester: p < 0.001), and hemoglobin (first trimester: p < 0.001; second trimester: p < 0.001; third trimester: p < 0.001) levels were associated with RLS. In the second and third trimesters, low magnesium (p < 0.001 and p < 0.001, respectively) and high creatinine (p = 0.027 and p < 0.001, respectively) levels were associated with RLS. Higher thyroid-stimulating hormone and free T4 levels were associated with RLS in the third trimester but not in the first and second trimesters (median: 2.4 vs. 2.1, p < 0.001; median: 1.5 vs. 1.2, p < 0.001). In the multivariate regression analysis, age (p = 0.034, OR: 1.060, 95% CI: 1.005-1.119), present BMI (p < 0.001, OR: 1.8884, 95% CI: 1.597-2.222), BMI before conception (p < 0.001, OR: 0.607, 95% CI: 0.513-0.718), gravida (p < 0.001, OR: 2.172, 95% CI: 1.547-3.049), low ferritin level (p < 0.001, OR: 6.396, 95% CI: 0.00744-0.010405), low vitamin B12 (p < 0.001, OR: 10.347, 95% CI: 0.00120-0.00176), low folate (p < 0.001, OR: 5.841, 95% CI: 0.00616-0.01240), RLS history before conception (p = 0.013, OR: 4.963, 95% CI: 1.402-17.57), and RLS family history (p < 0.001, OR: 7.914, 95% CI: 0.18760-0.31151) were found to be predictive factors for RLS in pregnancy. CONCLUSION More attention is needed to RLS during pregnancy to prevent or treat this syndrome.

Abstract
In this review, we provide a comprehensive overview of common sleep disorders during pregnancy, including their characterization, prevalence, risk factors, and possible contribution to maternal and fetal outcomes. We conducted a quasi-systematic literature search of the MEDLINE database and identified 744 studies from 1991 through 2021, inclusive, that met our inclusion criteria. We synthesized the existing literature on sleep disorders during pregnancy and highlighted controversies, research gaps, and needed clinical developments. Our review covers a range of sleep disorders, including insomnia, obstructive sleep apnea, restless legs syndrome, and circadian rhythm disorders. We discuss the prevalence of these disorders in pregnancy and their potential impact on maternal and fetal health outcomes. We also explore the relationship between sleep disorders, pre-pregnancy comorbidities such as obesity, and pregnancy-related conditions such as gestational diabetes mellitus and preeclampsia. In addition to summarizing the existing literature on sleep disorders during pregnancy, we also highlight opportunities for further research in this area. We suggest that future studies should strive to employ validated and objective measurement tools for sleep disorders and prioritize utilization of longitudinal methods with participant follow-up through postpartum, mid-life, menopause, and beyond. We also put forward investigation into the impact of circadian rhythm disruption on reproductive physiology and early pregnancy outcomes as an area of important work. Overall, our review provides valuable insights on sleep and reproduction and into common sleep disorders during pregnancy and their potential impact on maternal and fetal health outcomes.

Abstract
OBJECTIVE This study, accordingly, was conducted with the purpose of investigating the effect of progressive muscle relaxation exercise on the intensity of restless leg syndrome (RLS) and RLS-related quality of life and sleep in pregnant women with RLS. METHODS This one-centered, parallel randomized controlled study was conducted with 52 pregnant women. 27-28th of pregnancy, progressive muscle relaxation exercises training was shown and they were asked to practice them 3 times a week for 8 weeks. RESULTS It was found that the RLS Intensity Scale and PSQI posttest mean scores of the women in experiment group are lower on a statically significant level than the mean scores of the women in control group (p = 0.000 and p = 0.001). It was detected that the RLS-Qol posttest mean scores of the women in the experiment group are higher than the mean scores in the control group on a statistically significant level (p = 0.000). CONCLUSIONS It was seen that progressive muscle relaxation exercises alleviate RLS intensity and symptoms and improve RLS-related quality of life and sleep in pregnant women. PRACTICE IMPLICATION Progressive muscle relaxation exercises are beneficial for pregnant women and can be easily integrated into practice.

Abstract
Restless legs syndrome (RLS) is a multifactorial disease that patients describe as restlessness in their legs, which creates a desire to move their legs, especially in the evening and at rest. This study aims to investigate serum selenium levels in RLS and document the quality of sleep and life in pregnant women with RLS according to International Restless Legs Syndrome Study Group (IRLSSG) diagnostic criteria. Thirty-eight moderate to severe RLS patients with pregnancy at 38-41 weeks of gestation were determined as the case group, and 38 women with healthy gestational age-matched pregnancies were determined as the control group. Maternal serum selenium levels were compared between the RLS case group and the group of healthy pregnant women at the time of hospitalization for delivery. The Pittsburgh Sleep Quality Index (PSQI) and The Quality of Life Scale (SF-36) were applied to the patients. The mean selenium level (µg/L) was statistically significantly lower in the RLS group (53.24 ± 10.28), compared to the healthy pregnant population (58.95 ± 11.29) (P = 0.024). The PSQI score was significantly higher in the RLS case group (P = 0.033). Especially sleep efficiency (P = 0.018) and daytime dysfunction (P = 0.032) sub-parameters were affected. The SF-36 questionnaire was examined and a significant difference was detected between the two groups in role emotional (P = 0.026), social functioning (P = 0.023), and body pain (P = 0.044) sub-parameters. Serum selenium level was significantly lower, the sleep quality of the RLS group was impaired and their quality of life was affected in pregnant women with RLS. Further studies are needed to determine whether selenium replacement in pregnant women with RLS is feasible or not.

[PMID: 36831900 PMCID: PMC9954207 DOI: 10.3390/brainsci13020357] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 02/16/2023] [Accepted: 02/17/2023] [Indexed: 02/22/2023] Open
Abstract
OBJECTIVES Pregnancy is often associated with reduced sleep quality and an increase in sleep disorders, such as restless leg syndrome, obstructive sleep apnea, and insomnia. There are few studies investigating the prevalence of parasomnias in pregnancy, although they may be expected to be a significant problem, as disturbed sleep in this time period in addition to these sleep disorders may trigger parasomnia episodes. METHODS We conducted a survey using an online questionnaire focusing on a comparison of the prevalence of parasomnias in three time periods: 3 months before pregnancy, during pregnancy, and 3 months after delivery. We also inquired about psychiatric and neurological comorbidities, current anxiety and depression symptoms, and pregnancy complications. RESULTS A total of 325 women (mean age 30.3 ± 5.3 years) participated in the online survey. The overall number of reported parasomnias increased during pregnancy compared to the 3 months before pregnancy (p < 0.001) and decreased after childbirth (p < 0.001). Specifically, we found a significant increase in sleepwalking (p = 0.02) and night terrors (p < 0.001), as well as in vivid dreams (p < 0.001) and nightmares (p < 0.001) during pregnancy. A similar significant increase during pregnancy was reported for head explosion (p < 0.011). In contrast, the number of episodes of sleep paralysis increased after delivery (p = 0.008). At the individual level, an increase in the severity/frequency of individual parasomnia episodes was also observed during pregnancy. Participants whose vivid dreams/nightmares persisted after delivery had higher BDI-II and STAI-T scores. Our data also suggest a significant impact of migraines and other chronic pain, as well as complications during pregnancy, on the presence of parasomnia episodes in our cohort. CONCLUSIONS We have shown that the prevalence of parasomnias increases during pregnancy and needs to be targeted, especially by non-pharmacological approaches. At the same time, it is necessary to inquire about psychiatric and neurological comorbidities and keep in mind that more sleep disorders may be experienced by mothers who have medical complications during pregnancy.

Abstract
The two-process model of sleep regulation posits two main processes regulating sleep: the circadian process controlled by the circadian clock and the homeostatic process that depends on the history of sleep and wakefulness. The model has provided a dominant conceptual framework for sleep research since its publication ~ 40 years ago. The time of day and prior wake time are the primary factors affecting the circadian and homeostatic processes, respectively. However, it is critical to consider other factors influencing sleep. Since sleep is incompatible with other behaviors, it is affected by the need for essential behaviors such as eating, foraging, mating, caring for offspring, and avoiding predators. Sleep is also affected by sensory inputs, sickness, increased need for memory consolidation after learning, and other factors. Here, we review multiple factors influencing sleep and discuss recent insights into the mechanisms balancing competing needs.

Abstract
STUDY OBJECTIVES Vitamin D deficiency is associated with restless legs syndrome (RLS). However, a cutoff value for serum 25-hydroxyvitamin D (25[OH]D) level associated with RLS has yet to be clearly determined. We evaluated the association between 25(OH)D and RLS in pregnant women. METHODS Data from 203 pregnant women were evaluated using blood samples taken in the third trimester. Liquid chromatography-tandem mass spectrometry and ligand binding assays were used to measure 25(OH)D. RLS was diagnosed based on International Classification of Sleep Disorders, third edition, criteria. The cutoff value for serum 25(OH)D associated with RLS was explored using receiver operating characteristic (ROC) curve and classification and regression tree (CART) analyses. RESULTS The results of liquid chromatography-tandem mass spectrometry (x) and ligand binding assays (y) for serum 25(OH)D in the RLS (n = 35, 17.2%) and non-RLS (n = 168) groups showed a relationship of y = -2.65 + 0.08x . The RLS group showed lower serum 25(OH)D and folate levels. ROC curve and CART analyses revealed cutoff values of 10-12.7 ng/mL and 6.6-7.2 ng/mL for 25(OH)D and folate, respectively. Of the 5 women with RLS symptoms persisting at a moderate-to-severe level after delivery, 4 had 25(OH)D levels < 10 ng/mL and all had folate levels < 6 ng/mL. CONCLUSIONS Vitamin D and folate deficiency were associated with RLS in pregnant women and may be associated with persistent moderate-to-severe postpartum RLS symptomatology; it is essential to examine associations with RLS while accounting for measurement methods and assay systems.

Abstract
Restless legs syndrome (RLS) is a sensorimotor disorder that severely affects sleep. It is characterized by an urge to move the legs, which is often accompanied by periodic limb movements during sleep. RLS has a high prevalence in the population and is usually a life-long condition. While its origins remain unclear, RLS is initially highly responsive to treatment with dopaminergic agonists that target D2-like receptors, in particular D2 and D3, but the long-term response is often unsatisfactory. Over the years, several putative animal models for RLS have been developed, mainly based on the epidemiological and neurochemical link with iron deficiency, treatment efficacy of D2-like dopaminergic agonists, or genome-wide association studies that identified risk factors in the patient population. Here, we present the first systematic review of putative animal models of RLS, provide information about their face and construct validity, and report their role in deciphering the underlying pathophysiological mechanisms that may cause or contribute to RLS. We propose that identifying the causal links between genetic risk factors, altered organ functions, and changes to molecular pathways in neural circuitry will eventually lead to more effective new treatment options that bypass the side effects of the currently used therapeutics in RLS, especially for long-term therapy.

Abstract
This review provides a summary for obstetricians, midwives, other health professionals and women contemplating pregnancy about the interactions between pregnancy and breathing during sleep. This review will first examine the normal physiological changes of pregnancy and their relationship to sleep-disordered breathing (SDB), and it will then summarise the current knowledge of SDB in pregnancy. Many changes in the respiratory system during pregnancy, particularly during the third trimester, can alter respiratory function during sleep, increasing the incidence and severity of SDB. These changes include increased ventilatory drive and metabolic rate, reduced functional residual capacity and residual volume, increased alveolar-arterial oxygen gradients and changes in the upper airway. The clinical importance of these changes during pregnancy is demonstrated by the increased incidence of snoring and obstructive sleep apnoea hypopnoea syndrome. As SDB is associated with obesity, the increasing incidence of obesity pre-pregnancy will likely increase SDB during pregnancy over the next decade. If a physician is asked to review a pregnant patient, they should always consider the possibility of SDB.

Abstract
BACKGROUND: Restless legs syndrome (RLS) is a common sensorimotor disorder during pregnancy. The purpose of this study was to assess the prevalence of RLS and explore the associated risk factors and outcomes in Omani women in the first and third trimester and at 2-week postpartum. MATERIALS AND METHODS: This cross-sectional study included 305 pregnant women visiting four health centers in Muscat between May 2018 and October 2020. A structured questionnaire was used and data were collected through review of electronic records and face-to-face interviews. The International RLS Study Group criteria were used to diagnose RLS. Participants were interviewed during their first trimester, their third trimester, and at their 2-week postpartum visit. Results were presented as means and standard deviations or percentages, as appropriate. To assess the association between RLS and various variables, unpaired t-test or McNemar's test were used, as appropriate. RESULTS: The mean age at baseline was 29.8 ± 5.28 years. The prevalence of RLS was significantly higher in the third trimester (41.0%) than in the first trimester (15.7%) and postpartum period (15.1%) (P < 0.001), although there was no significant difference in severity. Family history and personal history of RLS were the only independent correlates of RLS (P < 0.001 and 0.002, respectively). No associations were noted with pregnancy and neonatal outcomes or other comorbidities, including anemia. However, there was a significant relationship between the development of RLS and weight gain during pregnancy (P = 0.023). CONCLUSION: One in six pregnant Omani women may be at risk of RLS during the first trimester, while one in 2–3 may be at risk in the third trimester, particularly those with a personal or family history of RLS and those who gain >12 kg during pregnancy.

Abstract
There is a dearth of literature studying restless leg syndrome (RLS) among pregnant patients in Pakistan. The objective of this study was to determine the prevalence and associated factors of RLS among pregnant Pakistani patients. It was conducted in 2018 among 478 women attending ante-natal check-up in the outpatient department of five hospitals in Karachi, Pakistan. Individuals were interviewed for socio-demographic information, the key criteria for RLS and its associated factors. RLS was reported in 54 (11%) individuals based on International Restless Legs Syndrome Study Group (IRLSSG) criteria. The mean age was 33.44 ± 4.42 years. Association between pregnant women with RLS and those without reveals statistically significant differences with increasing age (p=.01), gravida (p<.01) and para (p<.001). RLS was significant among working women (p=.001), during third trimester (p=.001), with insomnia (p<.001), use of tobacco (p<.001) and among women with gestational diabetes (p<.001), hypertension (p<.001). The study showed a low prevalence of RLS among women during pregnancy. It further reported gestational diabetes, hypertension, insomnia and tobacco use to be independently linked to RLS. Impact StatementWhat is already known on this subject? Pregnancy has been demonstrated to be strongly associated with development of secondary restless leg syndrome (RLS). RLS in pregnancy has also been shown to portend poor maternal and neonatal outcomes such as postpartum depression and preterm birth. Various conditions and lifestyle factors in pregnancy have been shown to be associated with the development of RLS, but there are variations in these across different populations.What do the results of this study add? The prevalence of RLS was only reported twice in pregnant patients in Pakistan and our research helps to address this data shortage. In addition, the results of our study document a strong association of RLS with gestational hypertension and gestational diabetes and also show that smoking and exercise were correlated with RLS during pregnancy, both of which were previously unstudied in the pregnant Pakistani population.What are the implications of these findings for clinical practice and/or further research? Demonstrating the prevalence of RLS in pregnant Pakistani patients highlights the need to screen these patients, particularly those with associated conditions identified in our findings, for RLS during antenatal visits and to treat their condition to improve maternal and neonatal outcomes.

Abstract
Sleep is vital to life, even when women enter into pregnancy state. Good sleep is important for a healthy pregnancy. Sleep disturbances are common during pregnancy and can be due to the change of pregnancy itself or the results of sleep disorders. There is growing evidence linking sleep disturbances with adverse maternal and fetal outcomes. Differentiation of sleep disorders in order to provide appropriate treatment as well as promoting good sleep for pregnant women is important. A multidisciplinary team to provide sleep care during antenatal period may be needed.

Abstract
Study Objectives The study had three primary goals. First, we estimated survey-assessed DSM-5 insomnia disorder rates in pregnancy, and described associated sociodemographics, and sleep-wake and mental health symptoms. Second, we derived cutoffs for detecting DSM-5 insomnia disorder using common self-report measures of sleep symptoms. Third, we identified clinically relevant cut-points on measures of nocturnal cognitive and somatic arousal. Methods Ninety-nine women (85.9% in the 2nd trimester) completed online surveys including DSM-5 insomnia disorder criteria, the Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Presleep Arousal Scale's Cognitive (PSASC) and Somatic (PSASS) factors, and Edinburgh Postnatal Depression Scale. Results DSM-5 insomnia disorder rate was 19.2%. Insomnia was associated with depression, suicidality, nocturnal cognitive and somatic arousal, and daytime sleepiness. An ISI scoring method that aligns with DSM-5 criteria yielded excellent metrics for detecting insomnia disorder and good sleep. Regarding quantitative cutoffs, ISI ≥ 10 and ISI ≥ 11 (but not ISI ≥ 15) were supported for detecting DSM-5 insomnia, whereas ISI ≤ 7 and ISI ≤ 9 performed well for detecting good sleep. PSQI cutoff of 5 was supported for detecting insomnia and good sleep. The optimal cutoff for nocturnal cognitive arousal was PSASC ≥ 18, whereas the optimal cutoff for somatic arousal was PSASS ≥ 13. Conclusions Insomnia disorder affects a large segment of pregnant women. Empirically derived cutoffs for insomnia, good sleep, cognitive arousal, and somatic arousal may inform case identification and future perinatal sleep research methodology.

Incidence of Catastrophic Health Expenditure and Its Determinants in Cancer Patients: A Systematic Review and Meta-analysis. APPLIED HEALTH ECONOMICS AND HEALTH POLICY 2021; 19:839-855. [PMID: 34318445 DOI: 10.1007/s40258-021-00672-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 06/21/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND Cancer is the third leading cause of mortality in the world, and cancer patients are more exposed to financial hardship than other diseases. This paper aimed to review studies of catastrophic healthcare expenditure (CHE) in cancer patients, measure their level of exposure to CHE, and identify factors associated with incidence of CHE. METHODS This study is a systematic review and meta-analysis. Several databases were searched until February 2020, including MEDLINE, Web of Science, Scopus, ProQuest, ScienceDirect and EMBASE. The results of selected studies were extracted and analyzed using a random effects model. In addition, determinants of CHE were identified. RESULTS Among the 19 studies included, an average of 43.3% (95% CI 36.7-50.1) of cancer patients incurred CHE. CHE varied substantially depending on the Human Development Index (HDI) of the country in which a study was conducted. In countries with the highest HDI, 23.4% of cancer patients incurred CHE compared with 67.9% in countries with the lowest HDI. Key factors associated with incidence of CHE at the household level included household income, gender of the household head, and at the patient level included the type of health insurance, education level of the patient, type of cancer and treatment, quality of life, age and sex. CONCLUSION The proportion of cancer patients that incur CHE is very high, especially in countries with lower HDI. The results from this review can help inform policy makers to develop fairer and more sustainable health financing mechanisms, addressing the factors associated with CHE in cancer patients.

Abstract
BACKGROUND Suicidal ideation (SI) and suicide planning (SP) are associated with an increased risk of future suicide. We performed a meta-analysis of observational studies to estimate the prevalence of SI and SP in patients with major depressive disorder (MDD) and its associated factors. METHODS A systematic literature search was conducted in PubMed, EMBASE, PsycINFO and Web of Science from their commencement date until 7 October 2020. Original studies containing data on the prevalence of SI and SP in individuals with MDD were analyzed. RESULTS Forty-six articles covering 53,598 patients were included in the meta-analysis. The overall prevalence of SI was 37.7% (95% confidence interval (CI): 32.3-43.4%) and the pooled prevalence of SP was 15.1% (95% CI: 8.0--26.8%). Subgroup analyses revealed that the timeframe over which SI was assessed, source of patients, study design, and diagnostic criteria were significantly associated with the pooled prevalence of SI. Meta-regression analyses revealed that the Hamilton Depression Rating Scale (HAMD) score and percentage of male participants were positively associated with the pooled prevalence of SI. Study quality and mean age were negatively associated with the pooled prevalence of SI. In contrast, survey year and study quality were negatively associated with pooled prevalence of SP LIMITATION: SI and SP were self-reported and subject to recall bias and impression management. CONCLUSIONS SI and SP are common in patients with MDD, especially among inpatients. Preventive measures and treatments focusing on factors associated with SI and SP may reduce the risk of suicide in patients with MDD.

Abstract
INTRODUCTION Data on seizure course during pregnancy in women with epilepsy are limited. In particular, little is known about the causes underlying possible seizure worsening in this population. We therefore set out to explore worsening, in pregnancy, of sleep-related hypermotor epilepsy (SHE), a syndrome in which seizures are known to be triggered by sleep fragmentation, a condition common in pregnancy. METHODS From a cohort of consecutive patients with epilepsy who had one or more deliveries between January 2008 and March 2018, we retrospectively compared the rates of seizure worsening during pregnancy in SHE versus other epilepsies (NSHE). Worsening was defined as an increase in seizure frequency compared with the rate for the year prior to conception, including seizure recurrence after a year of seizure freedom, and/or new occurrence of tonic-clonic seizures. RESULTS We considered data on 11 pregnancies in women with SHE and 104 pregnancies in women with NSHE. Seizures worsened in six SHE pregnancies (54.5%) versus 18 NSHE ones (17.3%) (OR adjusted for preconception seizure frequency and polytherapy = 5.7, 95% CI = 1.6-20.8, p = 0.019). CONCLUSIONS Women with SHE have a higher risk of seizure worsening in pregnancy. This finding should be considered from the perspective of patient counseling.

Abstract
Restless leg syndrome (RLS) is a multifactorial movement disorder, and pregnancy is seen as a risk factor. This study aims to determine the clinical and psychiatric causes of RLS with a case-control study. The hemogram, biochemistry data, thyroid function tests, and serum element levels of healthy pregnant women (n = 134) and pregnant women diagnosed with RLS (n = 119) were compared. Total Ca, Mg, K, and Na concentrations were measured with an inductively coupled plasma optical emission spectrometry (ICP-OES), and an atomic absorption spectrophotometer was used to measure total concentrations of Zn in all samples. The Beck Anxiety Inventory (BAI), the Beck Depression Inventory (BDI), and the Pittsburg Sleep Quality Index (PSQI) scores were also compared in both groups. Sonographic measurements showed that the fetal biparietal diameter and femur lengths were higher in the RLS group (p = 0.001, p = 0.048, respectively), and abortion history was higher in the RLS group (p = 0.016). Magnesium and zinc levels were lower (p < 0.001 for both) and BAI and PSQI scores were higher (p < 0.001 for both) in the RLS group, and there was no difference between the BDI (p = 0.269) scores. A statistically significant relationship was detected between the BAI and RLS scores in the control and RLS groups (p < 0.001 for both). This is the first study to show that magnesium and zinc deficiency may play a role in the etiology of RLS during pregnancy; the results also showed adverse perinatal outcomes such as high miscarriage.

Abstract
Restless legs syndrome (RLS) is one of the most common neurologic conditions, with an estimated prevalence in European and North American heritage populations of about 2% to 5%. Because RLS diagnosis is essentially clinical, a careful evaluation of the symptoms is mandatory. It is important to exclude RLS mimics and evaluate factors that could exacerbate RLS symptoms. It is mandatory to evaluate systemic iron parameters, because the initial treatment depends on this result. Other complementary tests could help support the diagnosis or exclude mimics. The decision about when and how to treat should be carefully tailored to each patient.

Abstract
This systematic review and meta-analysis evaluated the diagnostic accuracy of screening instruments for restless legs syndrome (RLS) and reports sensitivity, specificity, positive (PPV) and negative predictive values (NPV). Searches for primary studies were conducted in electronic databases. Of the 1541 citations identified, 52 were included in the meta-analysis. The methodological quality of each study was evaluated using QUADAS-2. Only 14 studies assessed the reference standard in all participants or in all screen-positives and a selection of screen-negatives. Bivariate meta-analysis of these 14 studies estimated median sensitivity to be 0.88 (0.72-0.96) and specificity 0.90 (0.84-0.93); based on a population prevalence of 5%, the calculated PPV was 0.31 (0.27-0.34). For all 52 studies, with either full or partial verification of RLS status, we constructed best-case scenario sensitivities and specificities at pre-defined levels of prevalence: across all samples, when prevalence is 5%, the median best-case scenario PPV is 0.48 with significant between-study heterogeneity. No RLS screening instruments can currently be recommended for use without an expert clinical interview in epidemiological studies. For conditions with statistically low prevalence such as RLS, the specificity, not the sensitivity, of a screening instrument determines true prevalence. Therefore, future instruments should maximize specificity. We provide guidelines on RLS ascertainment in epidemiological studies that requires a two-step process with clinical interview following a screening test, and given the poor reporting quality of many RLS epidemiological studies, we include an RLS reporting checklist.

Abstract
PURPOSE Restless leg syndrome (RLS) is a movement disorder which constitutes the most common and major risk group during pregnancy. The purpose of this study was to determine prevalence and severity of RLS during pregnancy and to investigate the effect of RLS on quality of life in pregnant women. METHODS This cross-sectional study was conducted in antenatal clinics of four different public hospitals. Data collected were pregnancy assessment form, RLS diagnostic criteria form, RLS severity scale, and SF-12 quality of life scale. RESULTS Among 718 pregnant women, mean age was 28.3±5.9 years (range 19 to 45). According to the diagnostic criteria of RLS, RLS prevalence was 22% (n=159). Of the 159 women with RLS, 41% had moderate severity and 40% had severe RLS. Prevalence of RLS in pregnant women increased with gestational week, working time during pregnancy, weight before pregnancy, total weight gain during pregnancy, and pre-pregnancy body mass index. Physical health scores, physical functioning scores, pain scores, emotional role difficulty scores, and social function scores were significantly lower in the pregnant women with RLS than without RLS (p <0.05). CONCLUSIONS Approximately one-fifth of the pregnant women had RLS, mostly in the third trimester, and the severity of RLS was predominantly moderate and severe. Pregnant women with RLS had poorer quality of life than pregnant women without RLS.

Abstract
IMPORTANCE Restless legs syndrome is a common neurologic disorder that is more prevalent in women than in men, and it has been suggested that female hormones may be involved in the disorder's pathophysiology. OBJECTIVE To determine whether women who underwent premenopausal bilateral oophorectomy were at increased risk of restless legs syndrome. DESIGN, SETTING, AND PARTICIPANTS This cohort study was performed using data from the Mayo Clinic Cohort Study of Oophorectomy and Aging-2 for a population in Olmsted County, Minnesota. There were 1653 women who underwent premenopausal bilateral oophorectomy before the age of 50 years for a benign indication between 1988 and 2007 and 1653 age-matched women (of same age plus or minus 1 year) in a reference group. Follow-up was conducted until the end of the study period (ie, December 31, 2014). Data were analyzed from January to July 2020. EXPOSURES Undergoing bilateral oophorectomy, as shown in medical record documentation. MAIN OUTCOMES AND MEASURES Diagnosis of restless legs syndrome, as defined using Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) criteria, was recorded. RESULTS Among 3306 women, the median (interquartile range) age at baseline was 44.0 (40.0-47.0) years. Women who underwent bilateral oophorectomy, compared with women who did not undergo this procedure, had a greater number of chronic conditions at the index date (eg, 300 women [18.1%] vs 171 women [10.3%] with ≥3 chronic conditions; overall P < .001), were more likely to have obesity (576 women [34.8%] vs 442 women [27.1%]; overall P < .001), and were more likely to have a history of anemia of any type (573 women [34.7%] vs 225 women [13.6%]; P < .001), iron deficiency anemia (347 women [21.0%] vs 135 women [8.2%]; P < .001), and restless legs syndrome before the index date (32 women [1.9%] vs 14 women [0.8%]; P = .008). Women who underwent bilateral oophorectomy prior to natural menopause had a higher risk of restless legs syndrome after the index date compared with women in the reference group (120 diagnoses vs 74 diagnoses), with an adjusted hazard ratio (HR) of 1.44 (95% CI, 1.08-1.92; P = .01). After stratification by indication for the bilateral oophorectomy, there was an increased risk of restless legs syndrome among women without a benign ovarian condition (HR, 1.52; 95% CI, 1.03-2.25; P = .04) but not among women with a benign condition (HR, 1.25; 95% CI, 0.80-1.96; P = .34). Treatment with estrogen therapy through the age of 46 years in women who underwent bilateral oophorectomy at younger ages was not associated with a difference in risk. CONCLUSIONS AND RELEVANCE This cohort study found that risk of restless legs syndrome was increased among women who underwent bilateral oophorectomy prior to menopause, especially those without a benign ovarian indication.

Sleep disturbances during pregnancy and adverse maternal and fetal outcomes: A systematic review and meta-analysis. Sleep Med Rev 2021; 58:101436.

Abstract
Sleep disturbances are highly prevalent in pregnancy and are frequently overlooked as a potential cause of significant morbidity. The association between sleep disturbances and pregnancy outcomes remains largely controversial and needs to be clarified to guide management. To evaluate the association between sleep disturbances and maternal complications and adverse fetal outcomes, we performed a systematic search of PubMed, Embase and Web of Science for English-language articles published from inception to March 6, 2020, including observational studies of pregnant women with and without sleep disturbances assessing the risk of obstetric complications in the antenatal, intrapartum or postnatal period, and neonatal complications. Data extraction was completed independently by two reviewers. We utilized the Newcastle-Ottawa Scales to assess the methodological quality of included studies and random-effect models to pool the associations. A total of 120 studies with 58,123,250 pregnant women were included. Sleep disturbances were assessed, including poor sleep quality, extreme sleep duration, insomnia symptoms, restless legs syndrome, subjective sleep-disordered breathing and diagnosed obstructive sleep apnea. Significant associations were found between sleep disturbances in pregnancy and a variety of maternal complications and adverse fetal outcomes. Overall sleep disturbances were significantly associated with pre-eclampsia (odds ratio = 2.80, 95% confidence interval: 2.38-3.30), gestational hypertension (1.74, 1.54-1.97), gestational diabetes mellitus (1.59, 1.45-1.76), cesarean section (1.47, 1.31-1.64), preterm birth (1.38, 1.26-1.51), large for gestational age (1.40, 1.11-1.77), and stillbirth (1.25, 1.08-1.45), but not small for gestational age (1.03, 0.92-1.16), or low birth weight (1.27, 0.98-1.64). Sleep disturbances were related to higher morbidities in pregnant women who are 30 y or older and overweight before pregnancy. The findings indicate that sleep disturbances, which are easily ignored and treatable for both pregnant women and clinical services, deserve more attention from health care providers during prenatal counseling and health care services.

Abstract
Restless legs syndrome (RLS) is characterized by an uncomfortable urge to move the legs while at rest, relief upon movement or getting up to walk, and worsened symptom severity at night. RLS may be primary (idiopathic) or secondary to pregnancy or a variety of systemic disorders, especially iron deficiency, and chronic renal insufficiency. Genetic predisposition with a family history is common. The pathogenesis of RLS remains unclear but is likely to involve central nervous system dopaminergic dysfunction, as well as other, undefined contributing mechanisms. Evaluation begins with a thorough history and examination, and iron measures, including ferritin and transferrin saturation, should be checked at presentation and with worsened symptoms, especially when augmentation develops. Augmentation is characterized by more intense symptom severity, earlier symptom occurrence, and often, symptom spread from the legs to the arms or other body regions. Some people with RLS have adequate symptom control with non-pharmacological measures such as massage or temperate baths. First-line management options include iron-replacement therapy in those with evidence for reduced body-iron stores or, alternatively, with prescribed gabapentin or pregabalin, and dopamine agonists such as pramipexole, ropinirole, and rotigotine. Second-line therapies include intravenous iron infusion in those who are intolerant of oral iron and/or those having augmentation with intense, severe RLS symptoms, and opioids including tramadol, oxycodone, and methadone. RLS significantly impacts patients' quality of life and remains a therapeutic area sorely in need of innovation and a further pipeline of new, biologically informed therapies.

Premenopausal Women With a Diagnosis of Endometriosis Have a Significantly Higher Prevalence of a Diagnosis or Symptoms Suggestive of Restless Leg Syndrome: A Prospective Cross-Sectional Questionnaire Study. Front Endocrinol (Lausanne) 2021; 12:599306. [PMID: 33854478 PMCID: PMC8040104 DOI: 10.3389/fendo.2021.599306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Accepted: 03/05/2021] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Endometriosis and restless leg syndrome (RLS) are both chronic conditions that can negatively affect a woman's quality of life. A higher prevalence of RLS is seen in women and particularly in those who are pregnant, suggesting a possible ovarian hormonal influence. Endometriosis is a common (affecting 1 in 10 women) estrogen driven gynecological condition, and the prevalence of RLS in women with symptoms or a diagnosis of endometriosis is unknown. METHODS A prospective, cross-sectional, observational self-completed questionnaire study was distributed to 650 pre-menopausal women attending the gynecological department at Liverpool Women`s Hospital over a period of 4 months. 584 questionnaires were returned and 465 completed questionnaires were included in the final dataset. Data on RLS-associated (The International Restless Leg Syndrome Study Group rating scale) and endometriosis-associated (modified-British Society of Gynaecological Endoscopists pelvic pain questionnaire) symptoms were collected. RESULTS Women who reported a prior surgical diagnosis of endometriosis had a greater risk of having a prior formal diagnosis of RLS (OR 4.82, 95% CI 1.66,14.02) and suffering RLS symptoms (OR 2.13, 95% CI 1.34-3.39) compared with those without a diagnosis. When women with either a formal surgical diagnosis or symptoms associated with endometriosis were grouped together, they also have a significantly increased risk of having either a formal diagnosis or symptoms suggestive of RLS (OR 2.49, 95% CI 1.30, 3.64). In women suffering with endometriosis-associated symptoms, the cumulative endometriosis-associated symptom scores demonstrated a modest positive correlation with RLS severity scores (r=0.42 95% CI 0.25 to 0.57). CONCLUSIONS This is the first study highlighting an association between the symptoms relevant to the two chronic conditions RLS and endometriosis, showing that women with a reported prior surgical diagnosis or symptoms suggestive of endometriosis have a significantly higher prevalence of a prior formal diagnosis or symptoms suggestive of RLS. This data will help in facilitating the discovery of novel therapeutic targets relevant to both conditions. The simultaneous treatment of these conditions could potentially lead to improvement in the overall quality of life for these women.

Abstract
OBJECTIVE To determine whether the incidence and risk factors of restless legs syndrome (RLS) in pregnancy differ by race/ethnicity, we estimated relative risks of demographic, socioeconomic, and nutritional factors in association with risk of any incident RLS in pregnancy in a cohort of 2,704 healthy pregnant women without prior RLS. METHODS Using data from the multicenter, multiracial National Institute of Child Health and Human Development (NICHD) Fetal Growth Studies-Singletons, we examined the incidence of RLS from early pregnancy to near delivery through up to 6 assessments. Multivariable Poisson models with robust variance were applied to estimate relative risks (RRs). RESULTS The cumulative incidence of RLS in pregnancy was 18.1% for all women, 20.3% for White women, 15.4% for Black women, 17.1% for Hispanic women, and 21.1% for Asian women. Among Hispanic women, older age (RR [reference ≤25 years]: 25-35 years, 1.51; 95% confidence interval [CI] 1.05-2.16; ≥35 years, 1.58; 95% CI 0.93-2.68), anemia (RR [reference no]: yes, 2.47; 95% CI 1.31-4.64), and greater total skinfolds of the subscapular and triceps sites, independent of body mass index (RR [reference quartile 1]: quartile 5, 2.54; 95% CI 1.30-4.97; p trend = 0.01) were associated with higher risk of RLS, while multiparity was associated with a lower risk (RR [reference nulliparity]: 0.69; 95% CI 0.50-0.96). In Black women, greater skinfolds and waist circumference were associated with higher risk of pregnancy RLS, although the trends were less clear. CONCLUSIONS The incidence of RLS in pregnancy was high and differed by race/ethnicity, which is likely accounted for by differences in other risk factors, such as age, parity, and nutritional factors.

Abstract
Restless leg syndrome (RLS) or Willis-Ekbom disease (WED) is an under-diagnosed, chronic, and progressive primary sensory-motor disorder. It is characterized by an uncontrollable urge to move the legs due to uncomfortable and sometimes painful sensations, with a diurnal variation. RLS can lead to severe sleep disturbances, a usual cause of consultation. The pathophysiology is known partially, and it is believed that there is an association between the different variants of genetic mutations combined with dopaminergic and brain iron dysregulation, which plays an important role. The data used for this study were extracted from the articles found in the PubMed database that discuss different gene variants, pathophysiology, and various methods of treatment. They also highlight the role of iron in the pathogenesis of RLS as it is required for the synthesis of tyrosine hydroxylase, which is the rate-limiting step for dopamine synthesis. This review article provides a clinically useful overview of RLS in terms of pathophysiological findings, its genetic associations, and therapeutic options by using the currently available literature. Because RLS presents with vague symptoms and shares similarities with many other diseases, it might be overlooked by many physicians resulting in underdiagnosis and under-treatment. While these discoveries provide a breakthrough in understanding the details of RLS, further studies are recommended as these studies are limited to animal models and provide a limited representation of the general population.

Abstract
PURPOSE OF REVIEW In this article, the different sleep-related movement disorders are discussed with special attention given to restless legs syndrome (RLS). RECENT FINDINGS The differential diagnosis of sleep-related movement disorders can often be challenging; therefore, it is essential to have accurate information to make a correct diagnosis. This article focuses on RLS, highlighting the change in the paradigm of initial treatment, the role played by iron (pathophysiologic and therapeutic), and how to approach possible complications occurring with long-term treatment. SUMMARY RLS is one of the most common neurologic conditions, and it is common in clinical practice to find patients experiencing symptoms suggestive of RLS. Neurologists must be careful and thorough in the diagnosis, excluding RLS mimics. The decisions regarding which specific sleep-related movement disorder is present and how it should be treated are important because in certain cases, especially in RLS, adverse effects and long-term complications are frequently reported with the use of certain drugs.

Abstract
PURPOSE OF THE REVIEW To review the data supporting the associations between sleep disorders and hypertensive disorders of pregnancy, their diagnosis, consequences, treatment, and potential mechanisms. RECENT FINDINGS The prevalence of sleep-disordered breathing, insomnia, and restless legs syndrome increases as pregnancy progresses secondary to physiologic changes associated with pregnancy. Sleep-disordered breathing is strongly associated with the development of gestational hypertension and preeclampsia, both of which are associated with increased risk of perinatal complications. Diagnosing sleep disorders in pregnant presents added challenges, but polysomnography remains the gold standard for diagnosing sleep-disordered breathing in this group. Sleep disorders, and especially sleep-disordered breathing, are highly prevalent among pregnant women and associated with hypertensive disorders of pregnancy. Clinicians should be mindful of this association and endeavor to identify at-risk women for further evaluation.

Abstract
Restless legs syndrome (RLS) affects one in five pregnant women. This review aims to synthesise evidence regarding gestational RLS and its consequences on pregnant women and neonates. Search of Embase, MEDLINE, PsycINFO, Maternity and Infant Care and Scopus was conducted in July 2018 using MeSH headings and keywords for 'restless legs syndrome' and 'pregnancy' or 'birth'. Our search identified 16 eligible studies from 12 countries published between 2004 and 2018 concerning gestational RLS and one or more maternal, delivery or neonatal outcomes. The most consistent associations were observed between gestational RLS and increased risks of gestational hypertension, pre-eclampsia, and peripartum depression. There were mixed findings for caesarean delivery, preterm birth and low birth weight, with the majority reporting no association with gestational RLS. Gestational RLS was not associated with postpartum haemorrhage, gestational diabetes, fetal distress, or low Apgar scores. Future research is needed to investigate whether effective treatment of RLS can mitigate these potential harms. Validated methods for diagnosing RLS in pregnancy would support research in this growing field.

Abstract
OBJECTIVES We sought to investigate the feasibility of a behavioral sleep intervention for insomnia, delivered through group prenatal care and the relationship of this intervention to improvements in insomnia symptoms and sleep quality. PARTICIPANTS Women receiving prenatal care and reporting a pre-pregnancy BMI of ≥25 kg/m2 and sleep duration of <6.5 h per night. METHODS Participants were randomized to group prenatal care or group prenatal care with a behavioral sleep intervention, adapted from cognitive behavioral therapy for insomnia (CBT-I) online program Go! to Sleep®. In the second trimester (T1), late third trimester (T2) and 6-8 weeks postpartum (T3) study assessments were completed including the Insomnia Severity Index, Pittsburgh Sleep Quality Index, fasting glucose and insulin and weight and height. Data were analyzed using independent samples t-tests, chi-square tests, correlations, and two-way repeated measures ANOVA where appropriate. P < .05 was set as the level of significance. RESULTS From May 2014 to April 2015, 311 women were evaluated for inclusion and 53 women were randomized to participate (27 intervention; 26 control), 15% were lost to follow up. The intervention group had lower third trimester and postpartum levels of moderate to severe insomnia (T2 50.0% vs 85.0% (p = .018) and T3 13.6% vs 52.4% (p-.008)) and mean insomnia severity scores (T2 (14.7 (±6.6) vs 19.3 (± 6.0) p = .02) and T3 (9.7 (±5.4) vs 15.1(±7.2) p = .01)) when compared to the control group. CONCLUSION A randomized controlled trial of a behavioral sleep intervention for insomnia delivered through group prenatal care led to improvements in insomnia symptoms.

Abstract
OBJECTIVE This study sought to determine whether there is an association between restless legs syndrome (RLS) and severe preeclampsia using a case-control study design. METHODS A total of 147 patients with severe preeclampsia and 147 patients with normal pregnancies were evaluated for symptoms of RLS. In the first phase, before or immediately after delivery, participants were given a questionnaire on common complaints experienced during pregnancy. Mixed with these complaints were the symptoms that comprised the diagnostic criteria for RLS. If a participant indicated she met the diagnositic criteria, she was informed about RLS. In the second phase, a severity evaluation was performed in this population using the International Restless Legs Syndrome Study Group Rating Scale. RESULTS Among the participants, independent of the presence of preeclampsia, 13.61% met the criteria for a diagnosis of RLS. There was no statistical difference between groups (severe preeclampsia: 12.93% vs. controls: 14.29%; odds ratio [OR] 0.89; 95% CI 0.46-1.74, P = 0.37). After analysis, 65% of patients with RLS had a score on the International Restless Legs Syndrome Study Group Rating Scale compatible with "very severe" or "severe" RLS. There was again no statistical difference between groups for the combination of "severe" and "very severe" scoring criteria (severe preeclampsia: 68.42% vs. controls: 61.90%; OR 1.33; 95% CI 0.36-4.93, P = 0.66) and "very severe" alone (severe preeclampsia: 21.05% vs. controls: 4.76%; OR 5.33; 95% CI 0.54-52.73, P = 0.11). CONCLUSION The prevalence of RLS among pregnant women in our study was in accordance with the medical literature and avoided the probable bias caused by the high number of other symptoms experienced during pregnancy. There were no significant differences between normotensive participants and those with severe preeclampsia. In general, symptom severity was high, with a tendency toward greater severity in patients with severe preeclampsia, but this difference did not reach statistical significance.

Abstract
The diurnal nature of restless legs syndrome (RLS) and its response to dopamine hint that hormones are central in RLS pathophysiology. Hypothyroidism has been linked to RLS, but studies are limited. This study's objective is to determine whether RLS is more prevalent in persons with hypothyroidism and whether hypothyroidism is more prevalent in RLS sufferers. Persons with hypothyroidism and controls were recruited through an on-line registry of potential research participants. RLS was assessed using the Cambridge-Hopkins questionnaire. RLS persons and controls were recruited through RLS Foundation and on-line registry advertisements and assessed for hypothyroidism by self-report. The International RLS Study Group Severity Scale assessed RLS severity; 266 hypothyroid subjects and 321 controls were comparable in age (52.3 ± 13.4 versus 53.9 ± 11.7 years; p = .14) and gender (91.7% versus 91.3% women; p = .85), as were 354 RLS and 313 controls (59.1 ± 13.2 versus 58.2 ± 13.6 years; p = .41; 80.8% versus 78.3% women; p = .42). Hypothyroid participants versus controls had a significantly higher prevalence of RLS (14.3% versus 8.1%; p = .02). RLS participants versus controls had a significantly higher prevalence of hypothyroidism (22.3% versus. 13.8%; p = .005). RLS severity was similar in persons with and without hypothyroidism. Among 73 persons with RLS and hypothyroidism, 14 previously were hyperthyroid versus 0 of 37 persons with hypothyroidism alone (p = .004). RLS prevalence is increased in individuals with hypothyroidism; hypothyroidism prevalence is increased in individuals with RLS. Persons with hypothyroidism and RLS are significantly more likely than those with hypothyroidism alone to have had hyperthyroidism prior to hypothyroidism. Associations between RLS and thyroid disease may shed light on complex biological mechanisms underlying RLS.

[PMID: 32217339 DOI: 10.1016/j.jad.2020.03.014] [Citation(s) in RCA: 40] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 02/26/2020] [Accepted: 03/03/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND Maternal use of benzodiazepines during pregnancy is common and has increased over the last decades. In this systematic review and meta-analysis, we studied the literature to estimate the worldwide use of benzodiazepines before, during and after pregnancy, which could help to estimate benzodiazepine exposure and to prioritize and guide future investigations. METHODS We systematically searched Embase, Medline Ovid, Web of Science and Cochrane Central up until July 2019 for studies reporting on benzodiazepine use before (12 months), during and after pregnancy (12 months). Random effects meta-analysis was conducted to calculate pooled prevalence estimates, as well as stratified according to substantive variables. RESULTS We identified 32 studies reporting on 28 countries, together reporting on 7,343,571 pregnancies. The worldwide prevalence of benzodiazepine use/prescriptions during pregnancy was 1.9% (95%CI 1.6%-2.2%; I2 97.48%). Highest prevalence was found in the third trimester (3.1%; 95%CI 1.8%-4.5%; I2 99.83%). Lorazepam was the most frequently used/prescribed benzodiazepine (1.5%; 95%CI 0.5%-2.5%; I2 99.87%). Highest prevalence was found in Eastern Europe (14.0%; 95%CI 12.1%-15.9%; I2 0.00%). LIMITATIONS All analyses revealed considerable heterogeneity. CONCLUSIONS Our meta-analysis confirmed that benzodiazepine use before, during and after pregnancy is prevalent. The relatively common use of benzodiazepines with possible risks for both mother and (unborn) child is worrying and calls for prescription guidelines for women, starting in the preconception period. Given the substantial proportion of children exposed to benzodiazepines in utero, future research should continue to study the short- and long-term safety of maternal benzodiazepine use during pregnancy and to explore non-pharmacological alternative treatments.

Abstract
Restless legs syndrome (RLS), also known as Willis-Ekbom disease (WED), is a common neurological disorder affecting up to 5% to 10% of the population, but it remains an underdiagnosed condition. RLS/WED is characterized by uncomfortable sensations, mainly in the legs, which appear during inactivity and worsen in the evening or at night. The prevalence of RLS/WED and periodic leg movements (PLMs) is increased in patients with sleep-disordered breathing, particularly in those with OSA, the most common sleep disorder encountered in sleep centers. New advances in the pathophysiology of RLS/WED have shown important implications for various genetic markers, neurotransmitter dysfunction, and iron deficiency. A practical approach to RLS/WED management includes an accurate diagnosis, the identification of reversible contributing factors, and the use of nonpharmacological therapies, including iron substitution (oral or IV) therapy. Many pharmacological agents are effective for the treatment of RLS/WED. Until recently, the first-line treatment of RLS/WED consisted of low-dose dopamine agonists (DA). However, given the fact that DAs cause high rates of augmentation of symptoms, international guidelines recommend that whenever possible the initial treatment of choice should be an α2δ ligand, and avoidance of dopaminergic agents unless absolutely necessary. If necessary, the lowest effective dose should be used for only the shortest possible time. The symptoms of RLS/WED can disrupt the quality of sleep as well as the quality of life. IV iron therapy may be considered in patients with refractory RLS. A better understanding of RLS/WED pathophysiology will allow patients to receive tailored therapy, resulting in an improved quality of life.

Abstract
Background Frequently observed sleep/wake problems among pregnant women need comprehensive evaluation. This study was conducted to clarify the sleep/wake problems among pregnant women without gestational complications during the second and third trimester and the effects of sleep/wake problems on delivery outcomes. Methods A total of 88 Japanese pregnant women participated in this study. In their second and third trimester, subjective sleep quality, insomnia severity, excessive daytime sleepiness (EDS), and restless legs syndrome/Willis-Ekbom disease (RLS/WED) were assessed using questionnaires; also, sleep disordered breathing (SDB) was screened using a pulse oximeter. Results From the second to the third trimester, an increasing tendency of sleep/wake problems was observed. During the third trimester, the percentages of women experiencing decreased subjective sleep quality, difficulty maintaining sleep (DMS), EDS, RLS/WED, and 3% oxygen desaturation index (ODI) values ≥5/h were 62.5, 45.5, 48.9, 9.1, and 29.5%, respectively. In a logistic regression analysis for EDS in the third trimester, the adjusted odds ratio (95% confidence interval) of total sleep duration < 6 h, moderate to severe DMS, and 3% ODI values ≥5/h were 3.25 (1.16–9.10), 4.74 (1.60–14.00), and 0.90 (0.28–2.89), respectively. Although short sleep durations, decreased subjective sleep quality, EDS, and SDB did not affect delivery outcomes or the infant’s condition, the percentage of women undergoing cesarean sections in the severe insomnia group was significantly higher (p = 0.008). Conclusions Sleep/wake problems were frequent during pregnancy, especially during the third trimester. EDS among pregnant women was associated with shorter sleep durations and DMS rather than SDB. The effect of factors related to insomnia on delivery outcomes should thus be considered a crucial problem among pregnant Japanese women without gestational complications in clinical practice.

Why Are Women Prone to Restless Legs Syndrome? INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17010368. [PMID: 31935805 PMCID: PMC6981604 DOI: 10.3390/ijerph17010368] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/03/2019] [Revised: 12/29/2019] [Accepted: 12/31/2019] [Indexed: 12/17/2022]
Abstract
Restless legs syndrome is a relatively common neurologic disorder considerably more prevalent in women than in men. It is characterized by an inactivity-induced, mostly nocturnal, uncomfortable sensation in the legs and an urge to move them to make the disagreeable sensation disappear. Some known genes contribute to this disorder and the same genes contribute to an overlapping condition—periodic leg movements that occur during sleep and result in insomnia. Dopamine and glutamate transmission in the central nervous system are involved in the pathophysiology, and an iron deficiency has been shown in region-specific areas of the brain. A review of the literature shows that pregnant women are at particular risk and that increased parity is a predisposing factor. Paradoxically, menopause increases the prevalence and severity of symptoms. This implies a complex role for reproductive hormones. It suggests that changes rather than absolute levels of estrogen may be responsible for the initiation of symptoms. Both iron (at relatively low levels in women) and estrogen (at relatively high oscillating levels in women) influence dopamine and glutamate transmission, which may help to explain women’s vulnerability to this condition. The syndrome is comorbid with several disorders (such as migraine, depression, and anxiety) to which women are particularly prone. This implies that the comorbid condition or its treatment, or both, contribute to the much higher prevalence in women than in men of restless legs syndrome.

Ann Thorac Med 2020; 15:9-14. [PMID: 32002041 PMCID: PMC6967142 DOI: 10.4103/atm.atm_206_19] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Accepted: 09/07/2019] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND: This cross-sectional case–control study aimed to assess the prevalence of restless legs syndrome (RLS) and its correlates and severity among Arab (Saudi) pregnant women attending antenatal care clinics. METHODS: We interviewed 742 consecutive pregnant women attending antenatal clinics face-to-face using the International RLS Study Group (IRLSSG) criteria. We assessed the severity of RLS using the IRLSSG severity scale for RLS (IRLS). A similar number of age-matched nonpregnant women were enrolled in a control group. RESULTS: Among the cases, 104 (14%) were in the first trimester, 232 (31.3%) in the second trimester, and 406 (54.7%) in the third trimester. The RLS prevalence in cases and controls was 30% and 26.5%, respectively, (P = 0.134). Among cases, severe/very severe RLS was diagnosed in 25% and mild/moderate in 75%, compared with 15% of controls having severe/very severe RLS and 85% having mild/moderate RLS (P < 0.001). Multivariate binary logistic regression analysis identified the following parameters as independent predictors of RLS: parity (odds ratio [OR] 1.113 [confidence intervals [CI] 1.012–1.223], P = 0.027), anemia (OR 1.452 [1.033–2.042], P = 0.03), diabetes mellitus (OR 1.734 [CI 1.084–2.774], P = 0.022), Vitamin D deficiency (OR 2.376 [CI 1.488–3.794],P < 0.001), and smoking (OR 3.839 [CI 1.463–10.074], P = 0.006). None of the cases had been diagnosed or treated for RLS in the antenatal clinics. CONCLUSION: RLS is common, but underdiagnosed, among Saudi pregnant women and nonpregnant women of childbearing age. The study revealed that RLS during pregnancy is linked to parity, anemia, diabetes mellitus, Vitamin D deficiency, and smoking.
