Abstract
Cannabinoids are lipophilic substances derived from Cannabis sativa that can exert a variety of effects in the human body. They have been studied in cellular and animal models as well as in human clinical trials for their therapeutic benefits in several human diseases. Some of these include central nervous system (CNS) diseases and dysfunctions such as forms of epilepsy, multiple sclerosis, Parkinson's disease, pain and neuropsychiatric disorders. In addition, the endogenously produced cannabinoid lipids, endocannabinoids, are critical for normal CNS function, and if controlled or modified, may represent an additional therapeutic avenue for CNS diseases. This review discusses in vitro cellular, ex vivo tissue and in vivo animal model studies on cannabinoids and their utility as therapeutics in multiple CNS pathologies. In addition, the review provides an overview on the use of cannabinoids in human clinical trials for a variety of CNS diseases. Cannabinoids and endocannabinoids hold promise for use as disease modifiers and therapeutic agents for the prevention or treatment of neurodegenerative diseases and neurological disorders.

Abstract
Context: Retrospective study of 36 individuals with sickle cell disease (SCD) certified for medical cannabis. Objective: We sought to examine whether medical cannabis certification was associated with a change in utilization of acute care medical services for patients with SCD. Methods: We identified patients with SCD certified for medical cannabis use between July 2014 and December 2021 using the New York State Prescription Monitoring Program (NYS PMP) and cross-matching to our electronic medical record. We estimated the mean incidences of Emergency Department (ED) visits, hospital admissions, inpatient days, and total acute encounters for SCD-related pain per month pre- and post-medical cannabis certification and used paired t-tests to assess the statistical significance of changes in hospital use. We stratified incidence based on whether patients had received a bone marrow transplant (BMT) at any point before or during the research period, since BMT is potentially an important covariate. Recertification rates and patients' reasons for choosing to recertify were qualitatively investigated through retrospective chart review. Results: The incidence of ED visits, hospital admissions, and total acute encounters per month for SCD-related pain decreased pre- to post-certification (p=0.02; p=0.02; p=0.01). These decreases lost statistical significance after stratifying patients based on BMT history. There was no statistically significant change in the number of days per month patients spent hospitalized in either the primary analysis or after stratification by BMT status. Forty-four percent of patients chose to be recertified. Thirty-six percent of patients cited concerns regarding the cost of medical cannabis. Conclusion: Our study did not show a statistically significant relationship between certification for medical cannabis and hospital use after addressing BMT history as a potentially important covariate. However, we were likely underpowered to detect any existing difference after patient data were stratified due to our small sample size. Regardless, 44% of patients chose to be recertified, indicating a perceived benefit and utility in further investigation of medical cannabis for this population with a larger analytic sample. Patient-reported benefits were improvement of pain and other symptoms, decreased opiate requirements, and decreased side effects compared to opiates.

Abstract
Pain is a common complication of sickle cell disease. Sickle cell pain can often be effectively managed by pediatricians in outpatient and hospital settings. Acute pain management should be initiated quickly. Patients need to be evaluated for sickle cell complications and other causes of pain. Nonsteroidal anti-inflammatory drugs and opioids are the mainstay of pain treatment, but additional therapies include hydration, local pain control, muscle relaxants, and nonpharmacologic approaches. Healthy lifestyle habits and good behavioral and mental health are important for preventing and coping with sickle cell disease pain. Disease-modifying therapies, such as hydroxyurea, can help prevent sickle hemoglobin polymerization and acute pain episodes. Because sickle cell disease largely affects people who are racialized minorities in the United States, health-care providers need to be aware of how their own personal biases may affect care of these patients.

Abstract
Sickle cell disease is a major public health concern due to its prevalence and associated morbidities. In high-income countries, diagnosis and treatment advancements have extended patient's lives and enabled women to embrace motherhood. Although the provision of care in specialist centres has reduced maternal-fetal complication rates, the mortality rate among pregnant women with sickle cell disease remains disproportionately high. Complications arise from vaso-occlusive events, worsening organ damage, thrombotic risks, infections, and pregnancy-related issues, such as pre-eclampsia, premature birth, small-for-gestational-age, and pregnancy loss. Effective management during pregnancy includes preconception planning, genetic counselling, education, and collaborative care. There is no consensus on the overall approach to managing pregnant women with sickle cell disease; however, fostering a collaborative relationship between health-care professionals and researchers is crucial for advancing the understanding and management of this illness. The disparities in health-care outcomes associated with ethnicity and economic insecurity affect patients with sickle cell disease but have not been examined extensively. Hence, health-care personnel need sufficient training to address these issues alongside broader societal efforts to confront racism and discrimination. Comprehensive national and global action plans are required to address the multifaceted challenges of sickle cell disease.

Abstract
Although descriptions of quality of life and patient reports of mood in sickle cell disease (SCD) have become more common in the literature, less is known about psychiatric illness prevalence, presentation, and treatment, particularly for adults. We provide a narrative review of what is known about common and debilitating psychiatric conditions such as depression, anxiety, and cognitive impairment, specifically for adults with SCD. We discuss the limitations of the current evidence, make provisional recommendations, and identify opportunities for research and improved care.

Abstract
Existing treatment for chronic pain in sickle cell disease (SCD) is opioid-dependent, which is ineffective and carries risks. We conducted a scoping literature review to assess the size and scope of available literature about controlled trials of therapies for SCD chronic pain and identify research gaps. The search strategy in PubMed and EMBASE utilized keywords for chronic pain and sickle cell and identified seven original articles that met inclusion criteria. Six of the studies recruited from clinics while one recruited from community sources. Cannabis and behavioral modification were associated with improvements in pain scores. However, existing evidence does not represent best practices for assessing chronic pain, and this along with small sample sizes prevents translation to clinical care. The limited evidence concerning treatment for SCD chronic pain highlights the need for larger trials of opioid alternatives and the utilization of chronic pain measures that capture nociplastic pain in SCD.

Abstract
There has been an increased interest of the scientific community in cannabis and its constituents for therapeutic purposes. Although it is believed that cannabinoids can be effective for a few different conditions and syndromes, there are little objective data that clearly support the use of cannabis, cannabis extracts or even cannabidiol (CBD) oil. This review aims to explore the therapeutic potential of phytocannabinoids and synthetic cannabinoids for the treatment of several diseases. A broad search covering the past five years, was performed in PubMed and ClinicalTrial.gov databases, to identify papers focusing on the use of medical phytocannabinoids in terms of tolerability, efficacy and safety. Accordingly, there are preclinical data supporting the use of phytocannabinoids and synthetic cannabinoids for the management of neurological pathologies, acute and chronical pain, cancer, psychiatric disorders and chemotherapy-induced emetic symptoms. However, regarding the clinical trials, most of the collected data do not fully support the use of cannabinoids in the treatment of such conditions. Consequently, more studies are still needed to clarify ascertain if the use of these compounds is useful in the management of different pathologies.

Abstract
Sickle cell disease (SCD) is an inherited disorder that impairs red blood cells (RBCs) and disrupts the delivery of oxygen to tissues. There is currently no cure. Symptoms can appear as early as six months of age and include anemia, acute episodes of pain, swelling, infections, delayed growth, and vision problems. A growing number of therapies are being investigated for reducing these episodes of pain, also known as vaso-occlusive crises (VOCs). The research literature evidence, however, currently includes far more approaches that have not shown superiority versus placebo than ones that have been proven effective. The purpose of this systematic review is to evaluate the body of randomized controlled trials (RCTs) to determine the quality of support for and against the use of a variety of current and emerging therapies for treading SCD VOCs. Several important new papers have emerged since previous systematic reviews with similar objectives were published. This review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and focused on PubMed exclusively. Only RCTs were sought, and no other filters, except for a five-year historical timeline cut-off, were used. Of the 46 publications that were returned in response to the query, 18 were ultimately accepted as meeting the pre-established inclusion criteria. The Cochrane risk-of-bias tool was utilized as a quality assessment measure, and the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) framework was used to assess the certainty of the evidence. Among the included publications, five out of 18 featured positive results with superiority and statistical significance versus placebo for either reduction in pain score or number/duration of VOCs. The approaches featured therapies ranging from de novo molecules to currently available drugs approved for other indications to naturally occurring metabolites such as amino acids and vitamins. A single therapy, arginine, was supported for both clinical endpoints: pain score reduction and shortened VOC duration. Currently, two therapies are approved by the United States Food and Drug Administration (FDA) and are commercially available (crizanlizumab, ADAKVEO and L-glutamine, Endari). All other therapies are investigational only in nature. Several studies included measurement of biomarker endpoints as well as clinical outcomes. Generally, beneficial outcomes related to improving biomarker levels did not also translate into statistically significant reduction of pain scores or number/duration of VOCs. While measuring biomarkers may contribute to the understanding of pathophysiology, it does not appear to directly offer predictive value toward treatment success clinically. It can be concluded that there exists a specific opportunity to design, fund, and execute investigations that both compare emerging and existing therapies versus one another and compare combinational therapies versus placebo.

Abstract
OBJECTIVES To assess the benefits and harms of cannabinoids in participants with pain. DESIGN Systematic review of randomised clinical trials with meta-analysis, Trial Sequential Analysis, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. DATA SOURCES The Cochrane Library, MEDLINE, Embase, Science Citation Index, and BIOSIS. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Published and unpublished randomised clinical trials comparing cannabinoids versus placebo in participants with any type of pain. MAIN OUTCOME MEASURES All-cause mortality, pain, adverse events, quality of life, cannabinoid dependence, psychosis, and quality of sleep. RESULTS We included 65 randomised placebo-controlled clinical trials enrolling 7017 participants. Fifty-nine of the trials and all outcome results were at high risk of bias. Meta-analysis and Trial Sequential Analysis showed no evidence of a difference between cannabinoids versus placebo on all-cause mortality (RR 1.20; 98% CI 0.85 to 1.67; P = 0.22). Meta-analyses and Trial Sequential Analysis showed that cannabinoids neither reduced acute pain (mean difference numerical rating scale (NRS) 0.52; 98% CI -0.40 to 1.43; P = 0.19) or cancer pain (mean difference NRS -0.13; 98% CI -0.33 to 0.06; P = 0.1) nor improved quality of life (mean difference -1.38; 98% CI -11.81 to 9.04; P = 0.33). Meta-analyses and Trial Sequential Analysis showed that cannabinoids reduced chronic pain (mean difference NRS -0.43; 98% CI -0.72 to -0.15; P = 0.0004) and improved quality of sleep (mean difference -0.42; 95% CI -0.65 to -0.20; P = 0.0003). However, both effect sizes were below our predefined minimal important differences. Meta-analysis and Trial Sequential Analysis indicated that cannabinoids increased the risk of non-serious adverse events (RR 1.20; 95% CI 1.15 to 1.25; P < 0.001) but not serious adverse events (RR 1.18; 98% CI 0.95 to 1.45; P = 0.07). None of the included trials reported on cannabinoid dependence or psychosis. CONCLUSIONS Cannabinoids reduced chronic pain and improved quality of sleep, but the effect sizes are of questionable importance. Cannabinoids had no effects on acute pain or cancer pain and increased the risks of non-serious adverse events. The harmful effects of cannabinoids for pain seem to outweigh the potential benefits.

Abstract
Dysmenorrhoea effects up to 90% of women of reproductive age, with medical management options including over-the-counter analgesia or hormonal contraception. There has been a recent surge in medicinal cannabis research and its analgesic properties. This paper aims to critically investigate the current research of medicinal cannabis for pain relief and to discuss its potential application to treat dysmenorrhoea. Relevant keywords, including medicinal cannabis, pain, cannabinoids, tetrahydrocannabinol, dysmenorrhoea, and clinical trial, have been searched in the PubMed, EMBASE, MEDLINE, Google Scholar, Cochrane Library (Wiley) databases and a clinical trial website (clinicaltrials.gov). To identify the relevant studies for this paper, 84 papers were reviewed and 20 were discarded as irrelevant. This review critically evaluated cannabis-based medicines and their mechanism and properties in relation to pain relief. It also tabulated all clinical trials carried out investigating medicinal cannabis for pain relief and highlighted the side effects. In addition, the safety and toxicology of medicinal cannabis and barriers to use are highlighted. Two-thirds of the clinical trials summarised confirmed positive analgesic outcomes, with major side effects reported as nausea, drowsiness, and dry mouth. In conclusion, medicinal cannabis has promising applications in the management of dysmenorrhoea. The global medical cannabis market size was valued at USD 11.0 billion in 2021 and is expected to expand at a compound annual growth rate (CAGR) of 21.06% from 2022 to 2030. This will encourage academic as well as the pharmaceutical and medical device industries to study the application of medical cannabis in unmet clinical disorders.

Abstract
Forty-one US jurisdictions (37 states) have legalized comprehensive medical cannabis programs since 1996. The number of qualifying conditions per jurisdiction varies from 5 to 29. Five (12%) of 42 qualifying conditions have conclusive or substantial evidence of efficacy and are listed in more than half of all jurisdictions. Half (50%) of qualifying conditions have no or insufficient scientific evidence of benefit from medical cannabis; 9% of qualifying conditions have limited evidence of harm from medical cannabis. The mean number of qualifying conditions per jurisdiction and the proportion of conditions with and without evidence of benefit have not changed since 1996.

Abstract
IMPORTANCE Sickle cell disease (SCD) is an inherited disorder of hemoglobin, characterized by formation of long chains of hemoglobin when deoxygenated within capillary beds, resulting in sickle-shaped red blood cells, progressive multiorgan damage, and increased mortality. An estimated 300 000 infants are born annually worldwide with SCD. Most individuals with SCD live in sub-Saharan Africa, India, the Mediterranean, and Middle East; approximately 100 000 individuals with SCD live in the US. OBSERVATIONS SCD is diagnosed through newborn screening programs, where available, or when patients present with unexplained severe atraumatic pain or normocytic anemia. In SCD, sickling and hemolysis of red blood cells result in vaso-occlusion with associated ischemia. SCD is characterized by repeated episodes of severe acute pain and acute chest syndrome, and by other complications including stroke, chronic pain, nephropathy, retinopathy, avascular necrosis, priapism, and leg ulcers. In the US, nearly all children with SCD survive to adulthood, but average life expectancy remains 20 years less than the general population, with higher mortality as individuals transition from pediatric to adult-focused health care systems. Until 2017, hydroxyurea, which increases fetal hemoglobin and reduces red blood cell sickling, was the only disease-modifying therapy available for SCD and remains first-line therapy for most individuals with SCD. Three additional therapies, L-glutamine, crizanlizumab, and voxelotor, have been approved as adjunctive or second-line agents. In clinical trials, L-glutamine reduced hospitalization rates by 33% and mean length of stay from 11 to 7 days compared with placebo. Crizanlizumab reduced pain crises from 2.98 to 1.63 per year compared with placebo. Voxelotor increased hemoglobin by at least 1 g/dL, significantly more than placebo (51% vs 7%). Hematopoietic stem cell transplant is the only curative therapy, but it is limited by donor availability, with best results seen in children with a matched sibling donor. While SCD is characterized by acute and chronic pain, patients are not more likely to develop addiction to pain medications than the general population. CONCLUSIONS AND RELEVANCE In the US, approximately 100 000 people have SCD, which is characterized by hemolytic anemia, acute and chronic pain, acute chest syndrome; increased incidence of stroke, nephropathy, and retinopathy; and a life span that is 20 years shorter than the general population. While hydroxyurea is first-line therapy for SCD, L-glutamine, crizanlizumab, and voxelotor have been approved in the US since 2017 as adjunctive or second-line treatments, and hematopoietic stem cell transplant with a matched sibling donor is now standard care for severe disease.

Abstract
Adults living with sickle cell disease are at risk for experiencing severe illness from coronavirus disease 2019 (COVID-19) due to the complexity of their disease. Additionally, self-management and navigating the healthcare system may be challenging during the COVID-19 pandemic. Therefore, we conducted telephone interviews with 25 participants to explore the experiences of Black adults living with sickle cell disease during the early months of the pandemic in the United States. Three overarching themes characterize their experiences: management of sickle cell disease was further complicated by the pandemic, fear of the virus contributed to physical and social isolation, and employment and financial challenges affected well-being. The pandemic contributed to changes in health care maintenance and had a disproportionate impact on this population. Addressing social and structural determinants of health and disruptions in health care accessibility is critical to advancing health and health care equity for individuals living with sickle cell disease.

Opioid-sparing effect of cannabinoids for analgesia: an updated systematic review and meta-analysis of preclinical and clinical studies. Neuropsychopharmacology 2022; 47:1315-1330. [PMID: 35459926 PMCID: PMC9117273 DOI: 10.1038/s41386-022-01322-4] [Citation(s) in RCA: 24] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 02/10/2022] [Accepted: 03/31/2022] [Indexed: 12/19/2022]
Abstract
Cannabinoid co-administration may enable reduced opioid doses for analgesia. This updated systematic review on the opioid-sparing effects of cannabinoids considered preclinical and clinical studies where the outcome was analgesia or opioid dose requirements. We searched Scopus, Cochrane Central Registry of Controlled Trials, Medline, and Embase (2016 onwards). Ninety-two studies met the search criteria including 15 ongoing trials. Meta-analysis of seven preclinical studies found the median effective dose (ED50) of morphine administered with delta-9-tetrahydrocannabinol was 3.5 times lower (95% CI 2.04, 6.03) than the ED50 of morphine alone. Six preclinical studies found no evidence of increased opioid abuse liability with cannabinoid administration. Of five healthy-volunteer experimental pain studies, two found increased pain, two found decreased pain and one found reduced pain bothersomeness with cannabinoid administration; three demonstrated that cannabinoid co-administration may increase opioid abuse liability. Three randomized controlled trials (RCTs) found no evidence of opioid-sparing effects of cannabinoids in acute pain. Meta-analysis of four RCTs in patients with cancer pain found no effect of cannabinoid administration on opioid dose (mean difference -3.8 mg, 95% CI -10.97, 3.37) or percentage change in pain scores (mean difference 1.84, 95% CI -2.05, 5.72); five studies found more adverse events with cannabinoids compared with placebo (risk ratio 1.13, 95% CI 1.03, 1.24). Of five controlled chronic non-cancer pain trials; one low-quality study with no control arm, and one single-dose study reported reduced pain scores with cannabinoids. Three RCTs found no treatment effect of dronabinol. Meta-analyses of observational studies found 39% reported opioid cessation (95% CI 0.15, 0.64, I2 95.5%, eight studies), and 85% reported reduction (95% CI 0.64, 0.99, I2 92.8%, seven studies). In summary, preclinical and observational studies demonstrate the potential opioid-sparing effects of cannabinoids in the context of analgesia, in contrast to higher-quality RCTs that did not provide evidence of opioid-sparing effects.

Abstract
Cannabis has long been regarded as a recreational substance in the Western world. The recent marketing authorization of some medicinal products of industrial origin and the introduction onto the market of inflorescences for medical use mean that medical doctors can now prescribe Cannabis-based medicines in those countries which allow it. Nevertheless, there is still considerable controversy on this topic in the scientific community. In particular, this controversy concerns: the plant species to be used; the pathologies that can be treated and consequently the efficacy and safety of use; the routes of administration; the methods of preparation; the type and dosage of cannabinoids to be used; and, the active molecules of interest. As such, although medical Cannabis has been historically used, the results of currently completed and internationally published studies are inconclusive and often discordant. In light of these considerations, the aim of this work is to analyse the current legislation in countries that allow the use of medical Cannabis, in relation to the impact that this legislation has had on clinical trials. First of all, a literature search has been performed (PubMed and SciFinder) on clinical trials which involved the administration of Cannabis for medical use over the last 3 years. Of the numerous studies extrapolated from the literature, only about 43 reported data on clinical trials on medical Cannabis, with these mainly being performed in Australia, Brazil, Canada, Denmark, Germany, Israel, Netherlands, Switzerland, the United Kingdom and the United States of America. Once the reference countries were identified, an evaluation of the legislation in relation to Cannabis for medical use in each was carried out via the consultation of the pertinent scientific literature, but also of official government documentation and that of local regulatory authorities. This analysis provided us with an overview of the different legislation in these countries and, consequently, allowed us to analyse, with greater awareness, the results of the clinical trials published in the last 3 years in order to obtain general interest indications in the prosecution of scientific research in this area.

Abstract
Sickle Cell Disease (SCD) is a disease that affects many around the world and often accounts for frequent hospital admissions every year, secondary to uncontrolled pain. Marijuana is increasingly being used for its medicinal ability to treat pain in chronic medical conditions. Therefore, it is imperative to determine how effective it would be in providing pain relief to patients with SCD. We systematically screened five databases for relevant data: PubMed, Medline, PubMed Central (PMC), Cochrane Library, and Google Scholar. The inclusion and exclusion criteria were implemented. A quality appraisal was then done using the Cochrane Bias assessment for randomized controlled trials (RCTs), Newcastle-Ottawa tool for observational studies, and Scale for the Assessment of Narrative Review Articles (SANRA) checklist for traditional review articles. From seven articles, information was gathered; one systematic review, one RCT, two surveys, one cross-sectional study, one retrospective study, and one questionnaire-based study. Our review concluded that based on the literature assessed, marijuana use in SCD patients either worsened their painful crises or offered little to no help compared to opioids or hydroxyurea usage. There were limited RCTs published in addition to papers investigating the long-term effects of marijuana use in SCD. We hope that further data is gathered in these areas to sufficiently address whether cannabis use is efficacious for pain relief in patients with SCD.

Abstract
OBJECTIVES To determine whether patients with sickle cell disease (SCD) who present to the emergency department (ED) with vasoocclusive pain crises (VOC), and have coexisting mental health (MH) diagnoses, are more likely to have increased health care utilization and more frequent opioid administration compared with those without coexisting MH conditions. METHODS This is a retrospective study of patients aged 5 to 18 years with SCD who presented to a tertiary care ED with a primary complaint of VOC between January 1, 2013, and December 31, 2017. We excluded patients with sickle cell trait and without a pain management plan in the electronic medical record. Outcomes included ED length of stay (LOS), admission rate, and opioid administration in the ED. Morphine equivalents were used to standardize opioid dosing. Mann-Whitney U and χ2 tests were used for univariate analysis. Multivariable logistic was performed for categorical and continuous outcomes, respectively, after adjusting for confounding factors. RESULTS We identified 978 encounters. We excluded 196 without a pain management plan and one with inaccurate ED LOS, resulting in 781 encounters (148 patients) for analysis. Coexisting MH diagnoses were present in 75.0% of encounters, with anxiety (83.0%) and depressive disorders (55.9%) being most common. Compared with SCD patients without coexisting MH diagnoses, those with coexisting MH diagnoses had significantly longer ED LOS (252 ± 139 minutes vs 232 ± 145 minutes, P = 0.03), longer median hospital LOS (1.4 ± 3.2 days vs 0.3 ± 2.4 days, P < 0.001) in univariate analyses, but these differences were no longer significant in adjusted regression models. Patients with coexisting MH diagnoses had higher frequency of opioid administration in the ED (85.6% vs 71.4%, P < 0.0001) and higher odds of receiving opioids (adjusted odds ratio, 2.07; 95% confidence interval, 1.28-3.33). CONCLUSIONS Patients with SCD and coexisting MH diagnoses presenting with VOC have greater odds of receiving opioids compared with patients with SCD without coexisting MH diagnoses. Our results indicate a need for more MH resources in this vulnerable population and may help guide future management strategies.

Abstract
The use of cannabis products to help with sleep and various other medical conditions by the public has increased significantly in recent years. Withdrawal from cannabinoids can lead to sleep disturbance. Here, we describe a patient who developed significant insomnia leading to worsening anxiety, mood, and suicidal ideation in the setting of medical cannabis withdrawal, prompting presentation to the Emergency Department and inpatient admission. There is a limited evidence base for the use of cannabis products for sleep. We provide a comprehensive review evaluating the literature on the use of cannabis products on sleep, including an overview of cannabis and related psychoactive compounds, the current state of the law as it pertains to the prescribing and use of these substances, and potential side effects and drug interactions. We specifically discuss the impact of cannabis products on normal sleep and circadian sleep-wake rhythms, insomnia, excessive daytime sleepiness, sleep apnea, parasomnias, and restless legs syndrome. We also describe the effects of cannabis withdrawal on sleep and how this increases relapse to cannabis use. Most of the studies are observational but the few published randomized controlled trials are reviewed. Our comprehensive review of the effects of cannabis products on normal sleep and sleep disorders, relevant to primary care providers and other clinicians evaluating and treating patients who use these types of products, shows that cannabis products have minimal to no effects on sleep disorders and may have deleterious effects in some individuals. Further research examining the differential impact of the various types of cannabinoids that are currently available on each of these sleep disorders is required.

Abstract
Significant changes have occurred in the policy landscape surrounding cannabis legalization, production, and use around the globe and across the United States. With widespread availability of novel cannabis and cannabis-based products, there is an urgent need to understand their safety and effectiveness for medical indications. Three primary barriers contribute to the difficulty in initiating research geared toward answering the most pressing public health questions: the US regulatory status of cannabis and cannabinoids, sources for cannabis and cannabinoid study medications, and limited funding and resources to support studies. Despite these hurdles, research is rapidly increasing, and recent changes in the United States have paved the way for exciting new work. Here, challenges and barriers to cannabis and cannabinoid research are described from the perspectives of the National Institute on Drug Abuse, National Institutes of Health; the US Food and Drug Administration; and 2 clinical researchers. Barriers specifically to studying cannabis, cannabinoids, and cancer are emphasized.

Abstract
Control of acute pain in oral and maxillofacial surgery is important for patient care and comfort. Oral surgical procedures are associated with tissue injury and inflammation. Acute pain can arise directly from a surgical procedure or from problems such as dental caries, infection, perforation of maxillary sinus, pericoronitis, and jaw fractures. The major factor in acute pain management is deciding on an appropriate intervention and/or analgesics that will provide the best pain relief. Multimodal pain control has taken a leading role in effectively managing acute pain. This article covers the different options available to dental clinicians.

Abstract
Pain is a major comorbidity of sickle cell disease (SCD). Patients with SCD may suffer from both acute and chronic pain. Acute pain is caused by recurrent and unpredictable episodes of vaso-occlusive crises (VOC), whereas the exact etiology of chronic pain is still unknown. Opioids are the mainstay for pain treatment, but the opioid epidemic has significantly altered access to prescription opioids and has brought concerns over their long-term use into the forefront, which have negatively impacted the treatment of sickle pain. Opioids remain potent analgesics but growing opioid-phobia has led to the realization of an unmet need to develop nonopioid therapies that can provide relief for severe sickle pain. This realization has contributed to the approval of 3 different drugs by the Food and Drug Administration (FDA) for the treatment of SCD, particularly to reduce VOC and/or have an impact on the pathobiology of SCD. In this review, we outline the challenges and need for validation of side-effects of opioids and provide an update on the development of mechanism-based translational therapies, specifically targeting pain in SCD.

Abstract
Adequate evidence exists in the literature indicating a relatively positive shift with regards to the legal acceptance of cannabis and cannabis-derived products for medicinal purposes in some countries. Concomitantly, scientists are showing renewed interest in cannabis-related research work. Over the years, clinical and preclinical studies have demonstrated the therapeutic significance of cannabinoids for diverse indications. Additionally, efforts are being made to develop cannabis-related products into acceptable prescription products. FDA authorization for the commercial use of four cannabinoid-derived products, available as oral dosage forms is a significant progress already. However, there are certain drawbacks associated with the conventional delivery forms of cannabinoids. These include low oral bioavailability due to hepatic degradation, gastric instability, poor water solubility, and the side effects experienced upon the use of high doses of psychotropic cannabinoids associated with heightened plasma concentrations of the drug. These are however, limitable with the aid of transcutaneous drug delivery. Emerging topical and transdermal strategies could be exploited for the successful development of highly effective delivery systems for cannabinoids. This review discusses the feasibility of delivering therapeutic cannabinoids via skin and provides a comprehensive account of the supporting research studies that have been reported in the literature till date.

Abstract
Background While pain is the hallmark of sickle cell disease (SCD), healthcare personnel are often ill-equipped to adequately treat patients who present in vaso-occlusive crisis (VOC). Although symptom severity varies from individual to individual, SCD is characterized by intervallic pain as a result of oxygen deprivation in tissues and organs. Regardless of pain severity, SCD patients are often viewed as drug seekers by healthcare personnel who have concerns regarding patients’ dependence on opioids which may lead to addiction. The objective was to assess the types and amount of opioids used to treat VOC in comparison to Centers for Disease Control opioid prescription guidelines. Methods Literature search was conducted using CINAHL, PubMed, the Cochrane Library, Web of Science and hand search. Data were analyzed from 1999 to 2018. Randomized trials, observational, and case studies involved hospitalized adults with SCD who were prescribed opioids to treat VOC. Quality assessment was conducted using Downs and Black checklist. Meta-analysis was not conducted. Results Five studies were conducted in the USA, Arabia and the Netherlands, and the USA and Canada were included. Participants were treated with either morphine or morphine milligram equivalent (MME). No study used the same method of opioid administration. Conclusions Patients with SCD who are hospitalized secondary to VOC mostly received opioids for pain well within the Centers for Disease Control and Prevention prescription guidelines. No uniform method exists. Additional research is warranted.

Disabil Health J 2021; 14:101107. [PMID: 33867318 DOI: 10.1016/j.dhjo.2021.101107] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 04/02/2021] [Accepted: 04/02/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Health related quality of Life (HRQOL) is an important consideration when managing chronic diseases, like sickle cell disease (SCD). Assessment of neuropathic pain (NP) and its association with HRQOL in SCD are rarely reported. OBJECTIVES To examine the prevalence of NP and its association with HRQOL in adult Jamaicans with SCD. METHODS Adult SCD patients were recruited consecutively and data were collected on socio-demographics, NP using Douleur Neuropathique 4 (DN4), and HRQOL using the Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me). Means, medians, t-tests, ANOVA tests, Wilcoxon Rank-sum tests, Kruskal-Wallis tests, Pearson's correlation and multivariate linear regression analyses were performed using STATA 14.2. RESULTS There were 236 respondents, with 56.8% female, mean age 33.2 years (SD: 11.6; range: 18-67 years), and 75% had homozygous SS genotype. NP was likely present in 26.7% of the population. The standardized ASCQ-Me (mean ± SD; ordered from lowest to best HRQOL domain scores) were: emotional impact 53.3 ± 10.1; sleep impact 56.1 ± 9.7; social function 57.7 ± 10.6; pain impact 58.6 ± 7.8; and stiffness impact 61.0 ± 7.3. On multivariate analyses, NP significantly reduced emotional and social functioning and worsened sleep and stiffness. Higher acute pain scores significantly worsened all HRQOL domains, while higher disease severity worsened all except stiffness. Obesity was associated with worse sleep and greater stiffness. Females with leg ulcers reported lower social functioning and unemployed females had greater pain impact. CONCLUSIONS NP is increasingly prevalent in SCD and worsens HRQOL. Gender specific studies are needed to understand the significantly poorer HRQOL in women.

Opioids are not a major cause of death of patients with sickle cell disease. Ann Hematol 2021; 100:1133-1138. [PMID: 33758998 DOI: 10.1007/s00277-021-04502-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Accepted: 03/17/2021] [Indexed: 10/21/2022]
Abstract
According to the Center of Disease Control and Prevention (CDC) database, the total number of deaths due to opioid overdose from 1999 through 2018 was 840,629. Given the alarming nature of these statistics, patients who requested prescription for opioids became targets of suspicion and possible accusation of maladaptive behavior. Patients with sickle cell disease (SCD) were often not exempt from such accusations and became guilty by association. In order to clarify the effect of opioids on the mortality of patients with SCD, the mortality rates for children and adults with SCD were investigated using the CDC Wide-ranging Online Data for Epidemiologic Research (WONDER) Multiple Cause of Death database which is based on all the death certificates issued in the USA from 1999 to 2018. The data showed that 15,765 patients with SCD died from 1999 to 2018. Only 348 patients with SCD died due to opioids. The CDC database contains 27 categories of death based on ICD-10 codes in patients with SCD, and opioids were the 19th ranking cause of death. Surprisingly the most common causes of death of patients with SCD included circulatory, infection, respiratory, genitourinary, and vaso-occlusive crises/acute chest syndrome disorders in decreasing frequency. The mean age of death of females was 41.9 years and of males 39.3 years (p < 0.0001). Death due to SCD and death due to SCD and opioids were highest in the Southern Region of the USA.

Opioids and Sickle Cell Disease: From Opium to the Opioid Epidemic. J Clin Med 2021; 10:jcm10030438.

Abstract
Sickle cell disease (SCD) is an inherited disorder of hemoglobin structure. The clinical effects of the sickle gene are pleiotropic in nature causing multiple phenotypic expressions associated with the various complications of the disease. The hallmark of the disease is pain that could be acute, chronic, nociceptive, or neuropathic that could occur singly or in various combinations. The acute vaso-occlusive painful crisis (VOC) is the most common cause of admissions to the Emergency Department and/or the hospital. Although progress has been made in understanding the pathophysiology of SCD as well as in developing preventive and curative therapies, effective pain management continues to lag behind and depend mostly on the use of opioids. This review describes the history of opioids from the ancient times of opium to the current use of the many controversial opioids. In addition, the major cause of death of patients with SCD is the complications of the disease itself and not the use of opioids. The use of opioids by patients with SCD has been stable over the years. Judicious use of opioids to treat sickle cell pain according to available guidelines could minimize the unnecessary suffering experienced by patients with SCD.

Abstract
Pain in Sickle Cell Disease (SCD) is a major comorbidity and unique with acute pain due to recurrent and episodic vaso-occlusive crises as well as chronic pain, which can span an individual's entire life. Opioids are the mainstay treatment for pain in SCD. Due to recent health crises raised by adverse effects including deaths from opioid use, pain management in SCD is adversely affected. Cannabis and its products are most widely used for pain in multiple conditions and also by patients with SCD on their own. With the availability of "Medical Cannabis" and approval to use cannabis as medicine across majority of States in the United States as well as over-the-counter preparations, cannabis products are being used increasingly for SCD. The reliability of many of these products remains questionable, which poses a major health risk to the vulnerable individuals seeking pain relief. Therefore, this review provides up to date insights into available categories of cannabis-based treatment strategies, their mechanism of action and pre-clinical and clinical outcomes in SCD. It provides evidence for the benefits and risks of cannabis use in SCD and cautions about the unreliable and unvalidated products that may be adulterated with life-threatening non-cannabis compounds.
