Effects of CBD supplementation on ambulatory blood pressure and serum urotensin-II concentrations in Caucasian patients with essential hypertension: A sub-analysis of the HYPER-H21-4 trial

HYPER-H21–4 was a randomized crossover trial that aimed to determine if cannabidiol (CBD), a non-intoxicating constituent of cannabis, has relevant effects on blood pressure and vascular health in patients with essential hypertension. In the present sub-analysis, we aimed to elucidate whether serum urotensin-II concentrations may reflect hemodynamic changes caused by oral supplementation with CBD. The sub-analysis of this randomized crossover study included 51 patients with mild to moderate hypertension that received CBD for five weeks, and placebo for five weeks. After five weeks of oral CBD supplementation, but not placebo, serum urotensin concentrations reduced significantly in comparison to baseline (3.31 ± 1.46 ng/mL vs. 2.08 ± 0.91 ng/mL, P < 0.001). Following the five weeks of CBD supplementation, the magnitude of reduction in 24 h mean arterial pressure (MAP) positively correlated with the extent of change in serum urotensin levels (r = 0.412, P = 0.003); this association was independent of age, sex, BMI and previous antihypertensive treatment (β ± standard error, 0.023 ± 0.009, P = 0.009). No correlation was present in the placebo condition (r = −0.132, P = 0.357). In summary, potent vasoconstrictor urotensin seems to be implicated in CBD-mediated reduction in blood pressure, although further research is needed to confirm these notions.

The modulatory role of cannabis use in subconcussive neural injury

Cannabis use has become popular among athletes, many of whom are exposed to repetitive subconcussive head impacts. We aimed to test whether chronic cannabis use would be neuroprotective or exacerbating against acute subconcussive head impacts. This trial included 43 adult soccer players (Cannabis group using cannabis at least once a week for the past 6 months, n = 24; non-cannabis control group, n = 19). Twenty soccer headings, induced by our controlled heading model, significantly impaired ocular-motor function, but the degrees of impairments were less in the cannabis group compared to controls. The control group significantly increased its serum S100B level after heading, whereas no change was observed in the cannabis group. There was no group difference in serum neurofilament light levels at any time point. Our data suggest that chronic cannabis use may be associated with an enhancement of oculomotor functional resiliency and suppression of the neuroinflammatory response following 20 soccer headings.

Clinical outcome data of anxiety patients treated with cannabis-based medicinal products in the United Kingdom: a cohort study from the UK Medical Cannabis Registry

Cannabis-based medicinal products (CBMPs) have been identified as novel therapeutics for generalised anxiety disorder (GAD) based on pre-clinical models; however, there is a paucity of high-quality evidence on their effectiveness and safety. This study aimed to evaluate the clinical outcomes of patients with GAD treated with dried flower, oil-based preparations, or a combination of both CBMPs. A prospective cohort study of patients with GAD (n = 302) enrolled in the UK Medical Cannabis Registry prescribed oil or flower-based CBMPs was performed. Primary outcomes were changes in generalised anxiety disorder-7 (GAD-7) questionnaires at 1, 3, and 6 months compared to baseline. Secondary outcomes were single-item sleep quality scale (SQS) and health-related quality of life index (EQ-5D-5L) questionnaires at the same time points. These changes were assessed by paired t-tests. Adverse events were assessed in line with CTCAE (Common Terminology Criteria for Adverse Events) v4.0.

Integrative Oncology’s 30-Year Anniversary: What Have We Achieved? A North American Naturopathic Oncology Perspective

In 1991 the U.S. Congress mandated that the National Institutes of Health (NIH) form the Office of Alternative Medicine to study alternative medical therapies, especially in oncology care. Shortly after, the National Cancer Institute (NCI) created its own division of complementary and alternative medicine (Office of Complementary and Alternative Medicine). At the genesis of the field 30 years ago, what were we hoping to see accomplished by now? In this article we take a look back at milestones, shortfalls and future directions. Exciting opportunities exist to direct our established subspeciality’s future directions and we have made valuable advances the field of integrative oncology over the last 30 years: 1, IV high dose ascorbate has clinical research-based applications when used concurrently with some chemotherapeutic agents. 2. Whole body, extracorporeal and locoregional hyperthermia are being applied in treating solid tumors, including brain tumors. 3. PDL-1 tumor microenvironment testing and PDL-1 inhibitor immunotherapies have surprisingly excellent outcomes in a subgroup of cancer patients. 4. Tumor DNA sequencing (resected tumor and circulating tumor DNA in blood) has led to personalized precision targeted treatments. 5. Glucose metabolism’s role in cancer progression is better understood and better therapies are available (e.g., intermittent fasting, metformin). 6. Medical cannabis has a larger role in treating chemotherapy-related side effects and shows promise for anti-proliferative effects.

Tetrahydrocannabinol and Cannabidiol in Tourette Syndrome

Tourette syndrome is characterized by chronic motor and vocal tics. There is preliminary evidence of benefit from cannabis products containing D9-tetrahydrocannabi- nol (THC) and that coadministration of cannabidiol (CBD) improves the side-effect profile and safety.In this double-blind, crossover trial, participants with severe Tourette syndrome were randomly assigned to a 6-week treatment period with escalating doses of an oral oil containing 5 mg/ml of THC and 5 mg/ml of CBD, followed by a 6-week course of placebo, or vice versa, separated by a 4-week washout period. The primary outcome was the total tic score on the Yale Global Tic Severity Scale (YGTSS; range, 0 to 50 [higher scores indicate greater severity of symptoms]). Secondary outcomes included video-based assessment of tics, global impairment, anxiety, depression, and obsessive-compulsive symptoms. Out- comes were correlated with plasma levels of cannabinoid metabolites. A computerized cogni- tive battery was administered at the beginning and the end of each treatment period.

Neuronal Cannabinoid CB1 Receptors Suppress the Growth of Melanoma Brain Metastases by Inhibiting Glutamatergic Signalling

An estimated 60% of melanoma patients develop melanoma brain metastases (MBMs). However, the molecular factors that govern the growth of MBMs are still unknown. The excitatory neurotransmitter glutamate has been shown to control the proliferation of various types of cancer cells within the brain parenchyma, but the cellular sources and molecular mechanisms involved in this process remain unclear. By their well-known role in inhibiting synaptic glutamate release, cannabinoid CB1 receptors (CB1Rs) located on glutamatergic nerve terminals are conceivably well-positioned to control the growth of MBMs. In silico data mining in cancer-genome atlases and in vitro studies with melanoma cell lines supported that a glutamate-NMDA receptor axis drives melanoma cell proliferation. Strikingly, grafting melanoma cells into the brain of mice lacking CB1Rs selectively in glutamatergic neurons increased tumour size and concomitantly activated NMDA receptors on tumour cells. Altogether, our findings reveal an unprecedented role of neuronal CB1Rs in controlling MBMs.

Multiple Sclerosis and Use of Medical Cannabis: A Retrospective Review of a Neurology Outpatient Population

Patients diagnosed as having multiple sclerosis (MS) experience a wide range of symptoms requiring pharmacologic management, and many do not achieve adequate symptom control. The purpose of this study was to evaluate the role of medical cannabis (MC) as part of a comprehensive treatment plan for patients with MS. A retrospective medical record review of 141 patients with MS receiving MC for symptom management was conducted. Data were collected for up to 4 follow-up appointments after initiation of MC. Outcomes included changes in MS symptoms, medication changes, adverse events, and changes in cognition and mobility.

Cannabinoids in Treating Parkinson’s Disease Symptoms: A Systematic Review of Clinical Studies

Parkinson’s disease (PD) is a serious neurodegenerative condition impacting many individuals worldwide. There is a need for new non-invasive treatments of PD. Cannabinoids in the form of cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC) may offer utility as treatment, and our objective was hence to conduct a systematic review regarding the clinical evidence for the efficacy and safety of cannabinoids in treating PD.

Daily associations with cannabis use and sleep quality in anxious cannabis users

Cannabis is increasingly used to self-treat anxiety and related sleep problems, without clear evidence of either supporting or refuting its anxiolytic or sleep aid effects. In addition, different forms of cannabis and primary cannabinoids ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD) have differing pharmacological effects.Cannabis is increasingly used to self-treat anxiety and related sleep problems, without clear evidence of either supporting or refuting its anxiolytic or sleep aid effects. In addition, different forms of cannabis and primary cannabinoids ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD) have differing pharmacological effects.Thirty days of daily data on sleep quality and cannabis use were collected in individuals who use cannabis for mild-to-moderate anxiety (n = 347; 36% male, 64% female; mean age = 33 years). Participants self-reported both the form (flower or edible) and the ratio of THC to CBD in the cannabis used during the observation period.

CBD as a Physiological Modulator for Cancer

The current standard-of-care treatment regimens for cancer frequently have serious and irreversible adverse effects. Ideally, therapeutic modalities should help control symptoms and improve the patient’s quality of life while causing minimal or no toxic effects. In this regard, it is worth examining cannabidiol (CBD) for its potential anticancer properties. CBD may possess antitumor activity through several mechanisms, including regulating reactive oxygen species, endoplasmic reticulum stress, inflammation, and immune modulation. In addition, pre-clinical studies indicate that CBD is a potential modulator of growth factors and induces apoptosis in tumor cells. This review summarizes the evidence regarding the effects of CBD as a non-toxic adjuvant in cancer care.

Assessment of clinical outcomes in patients with fibromyalgia: Analysis from the UK Medical Cannabis Registry

There are limited therapeutic options for individuals with fibromyalgia. The aim of this study is to analyze changes in health-related quality of life and incidence of adverse events of those prescribed cannabis-based medicinal products (CBMPs) for fibromyalgia.  Patients treated with CBMPs for a minimum of 1 month were identified from the UK Medical Cannabis Registry. Primary outcomes were changes in validated patient-reported outcome measures (PROMs). A p-value of <.050 was deemed statistically significant.

Marijuana use is inversely associated with liver steatosis detected by transient elastography in the general United States population in NHANES 2017–2018: A cross-sectional study

Whole-plant medical cannabis (MC) products are widely used for controlling symptoms associated with Parkinson’s disease (PD). Despite its widespread use, few studies have investigated the long-term impact of MC on the progression of PD or its safety profile. This study examined the effects of MC on PD in a real-life setting. A retrospective case-control study of 152 idiopathic PD patients (mean age 69.1 ± 9.0 years), followed at the Sheba Medical Center Movement Disorders Institute (SMDI) from 2008 to 2022 was conducted. Seventy-six patients who used licensed whole-plant medical cannabis (MC) for at least a year were compared to a matched group who did not receive MC in terms of their Levodopa Equivalent Daily Dose (LEDD), Hoehn and Yahr (H&Y) stage, and cognitive, depressive, and psychotic symptoms.
