humulene and Chronic-Disease

The present study aimed to assess the prevalence of symptoms of anxiety and depression among health professionals in the three most affected regions in Cameroon.. The study was a descriptive cross-sectional type. Participants were health care professionals working in the three chosen regions of Cameroon. The non_probability convinient sample technique and that of the snowball were valued via a web questionnaire. The non-exhaustive sample size was 292. The diagnosis of anxiety and depression was made by the HAD (Hospital Anxiety and Depression scale).. Les auteurs rapportent que le secteur médical est classé à un plus grand risque de contracter le COVID-19 et de le propager potentiellement à d’autres. Le nombre sans cesse croissant de cas confirmés et suspects, la pression dans les soins, l’épuisement des équipements de protection individuelle et le manque de médicaments spécifiques peuvent contribuer à un vécu anxio-dépressif significatif. La présente étude s’est donnée pour ambition d’évaluer la prévalence des symptômes de l’anxiété et de la dépression chez les professionnels de santé dans les trois Régions les plus concernées au Cameroun.. Le choix des trois Régions du Cameroun se justifie non seulement par le fait qu’elles totalisent 95,8 % des cas de coronavirus au pays depuis le début de la pandémie, mais aussi parce qu’elles disposent de plus de la moitié des personnels de santé (56 %). Il s’agit d’une étude transversale, descriptive et analytique. Les participants sont des professionnels de la santé en service dans les Régions du Centre, Littoral et de l’Ouest du Cameroun. La méthode d’échantillonnage non probabiliste de convenance couplée à celle de boule de neige via un web questionnaire a été adoptée. La collecte des données a duré du 5 au 19 avril 2020, intervalle de temps après lequel on n’avait plus eu de répondants. À la fin de cette période, la taille de l’échantillon non exhaustive était de 292 professionnels. Le diagnostic de l’état anxio-dépressive était posé via l’échelle de HAD (Hospital Anxiety and Depression scale). Dans le HAD, chaque réponse cotée évalue de manière semi-quantitative l’intensité du symptôme au cours de la semaine écoulée. Un score total est obtenu ainsi que des scores aux deux sous-échelles : le score maximal est de 42 pour l’échelle globale et de 21 pour chacune des sous-échelles. Le coefficient alpha de Cronbach est de 0,70 pour la dépression et de 0,74 pour l’anxiété. Certains auteurs après plusieurs travaux ont proposé qu’une note inférieure ou égale à 7 indique une absence d’anxiété ou de dépression ; celle comprise entre 8 et 10 suggère une anxiété ou une dépression faible à bénigne ; entre 11 et 14, pour une anxiété ou une dépression modérée ; enfin, une note comprise entre 15 et 21 est révélatrice d’une anxiété sévère. Le logiciel Excel 2013 et Epi Info version 7.2.2.6 ont été utilisés pour les traitements statistiques. Les liens entre les variables ont été considérées significatifs pour une valeur de. L’amélioration des conditions de travail et notamment la fourniture d’équipement de protection, la mise en place des cellules spéciales d’écoute pour le personnel de santé pourraient être proposées.. Taken together with satisfactory selectivity index (SI) values, the acetone and methanol extracts of. During a mean follow-up period of 25.6 ± 13.9 months, 38 (18.4%) VAs and 78 (37.7%) end-stage events occurred. Big ET-1 was positively correlated with NYHA class (. In primary prevention ICD indication patients, plasma big ET-1 levels can predict VAs and end-stage events and may facilitate ICD-implantation risk stratification.. Beyond age, cognitive impairment was associated with prior MI/stroke, higher hsCRP, statin use, less education, lower eGFR, BMI and LVEF.. These data demonstrate that even a short period of detraining is harmful for elderly women who regularly participate in a program of strength training, since it impairs physical performance, insulin sensitivity and cholesterol metabolism.. Exposure to PM. Respiratory sinus arrhythmia is reduced after PVI in patients with paroxysmal AF. Our findings suggest that this is related to a decrease in cardiac vagal tone. Whether and how this affects the clinical outcome including exercise capacity need to be determined.. BDNF and leptin were not associated with weight. We found that miR-214-5p exerted a protective role in I/R injured cardiac cells by direct targeting FASLG. The results indicated that the MGO injection reduced all CCl. The hepatoprotective effects of MGO might be due to histopathological suppression and inflammation inhibition in the liver.. OVEO showed moderate antifungal activity, whereas its main components carvacrol and thymol have great application potential as natural fungicides or lead compounds for commercial fungicides in preventing and controlling plant diseases caused by. PF trajectories were mainly related to income, pregestational BMI, birth weight, hospitalisation due to respiratory diseases in childhood, participant's BMI, report of wheezing, medical diagnosis and family history of asthma, gestational exposure to tobacco and current smoking status in adolescence and young adult age.. In chronic pain patients on opioids, administration of certain benzodiazepine sedatives induced a mild respiratory depression but paradoxically reduced sleep apnoea risk and severity by increasing the respiratory arousal threshold.. Quantitative measurements of sensory disturbances using the PainVision. The serum level of 20S-proteasome may be a useful marker for disease activity in AAV.. The electrophysiological data and MD simulations collectively suggest a crucial role of the interactions between the HA helix and S4-S5 linker in the apparent Ca. Invited for the cover of this issue are Vanesa Fernández-Moreira, Nils Metzler-Nolte, M. Concepción Gimeno and co-workers at Universidad de Zaragoza and Ruhr-Universität Bochum.

To review the evidence regarding a decrease in worldwide sperm parameters and discuss potential causative factors.. The topic of worldwide decline in sperm parameters is contentious; however, recent high-quality studies have demonstrated that there is indeed a decline in sperm parameters. Several retrospective and basic science studies have shown possible links for this decline in sperm parameters such as obesity, diet, and environmental toxins.. There exist substantial data to suggest a decline in sperm counts over time. Although causative factors have yet to be fully elucidated, potential causes include, increased rates of obesity, poor diet, and exposure to environmental toxins. How this decline in sperm counts reflects fertility has yet to be determined. As such, further studies are necessary to evaluate whether this decline in sperm count correlates with decreased fecundity and how to identify and mitigate potential causative factors.

The present investigation aimed to provide an objective narrative review of the existing literature pertaining to the benefits and harms of marijuana use for the treatment of the most common medical and psychological conditions for which it has been allowed at the state level. Common medical conditions for which marijuana is allowed (i.e., those conditions shared by at least 80 percent of medical marijuana states) were identified as: Alzheimer's disease, amyotrophic lateral sclerosis, cachexia/wasting syndrome, cancer, Crohn's disease, epilepsy and seizures, glaucoma, hepatitis C virus, human immunodeficiency virus/acquired immunodeficiency syndrome, multiple sclerosis and muscle spasticity, severe and chronic pain, and severe nausea. Post-traumatic stress disorder was also included in the review, as it is the sole psychological disorder for which medical marijuana has been allowed. Studies for this narrative review were included based on a literature search in PsycINFO, MEDLINE, and Google Scholar. Findings indicate that, for the majority of these conditions, there is insufficient evidence to support the recommendation of medical marijuana at this time. A significant amount of rigorous research is needed to definitively ascertain the potential implications of marijuana for these conditions. It is important for such work to not only examine the effects of smoked marijuana preparations, but also to compare its safety, tolerability, and efficacy in relation to existing pharmacological treatments.

Our purpose in this article is to review the effects of recreational drugs, used either on their own but principally combined with alcohol consumption, in determining hepatic injury or influencing the evolution of some chronic diseases of the liver, specifically HCV infection and NAFLD. A deleterious role of daily use of recreational drugs, in particularly cannabis, has been shown to demonstrate clearly a rapid progression of fibrosis and steatosis, leading to a major severity in patients with chronic hepatitis C. On the other hand, the effects of the misuse of these substances on NAFLD, the main obesity-related comorbidity, leading to addiction, is still to be elucidated even though some clues to the recreational drugs hepatotoxicity are already present in the literature. This short review aims at raising awareness about this topic.

Cannabis can have negative effects in its users, and a range of acute and chronic health problems associated with cannabis use has been dentified. Acute cannabis consumption is rarely lethal but it is associated with an increased risk of motor vehicle accident because of longer reaction time or impaired motor coordination. Chronic effects of cannabis use include generally cardiovascular and respiratory consequences but there are also oral, gastrointestinal, cutaneous and mucous, metabolic, gynecologic and obstetrical, sexual consequences, and cancer But associated tobacco smoking or other potential confounders may explain part of those somatic consequences.

The specialty of oral and maxillofacial surgery has had at its core the foundations of anesthesia and pain and anxiety control. This article attempts to refamiliarize the reader with clinical pearls helpful in the management of patients with chronic pain conditions. The authors also hope to highlight the interplay of chronic pain and psychology as it relates to the oral and maxillofacial surgery patient. To that end, the article outlines and reviews the neurophysiology of pain, the definitions of pain, conditions encountered by the oral and maxillofacial surgeon that produce chronic pain, the psychological impact and comorbidities associated with patients experiencing chronic pain conditions, and concepts of multimodal treatment for patients experiencing chronic pain conditions.

Stroke associated with drug abuse has been frequently reported, particularly in young patients. The most commonly implicated drugs include cocaine, heroine, and amphetamines. Despite its widespread abuse, cannabis associated stroke is only infrequently reported. The cause and effect association between cannabis use and stroke is not firmly established. Presuming that cannabis may cause stroke, potential pathophysiologic mechanisms are not known. In this paper, we shall review the literature linking cannabis use and stroke and possible mechanisms supporting this link.

Cannabis preparations have been used as a remedy for thousands of years in traditional medicine. Clinical use of cannabinoid substances is restricted, due to legal and ethical reasons, as well as limited evidence showing benefits.. To assess the efficacy and harms of cannabis preparations in the treatment of chronic pain.. Systematic review and meta-analysis of double-blind randomized controlled trials that compared any cannabis preparation to placebo among subjects with chronic pain. An electronic search was made in Medline/Pubmed, Embase, and The Cochrane Controlled Trials Register (TRIALS CENTRAL) of all literature published until February 2008, as well as specific web pages devoted to cannabis. Studies were cross-checked, selected, and assessed.. Eighteen trials were included. The efficacy analysis (visual analog scales) displayed a difference in standardized means in favor of the cannabis arm of -0.61 (-0.84 to -0.37), with statistical homogeneity (I(2) = 0.0%; P = 0.50). For the analysis of harms, the following Odds Ratios (OR) and number needed to harm (NNH) were obtained: for events linked to alterations to perception, OR: 4.51 (3.05-6.66), NNH: 7 (6-9); for events affecting motor function, 3.93 (2.83-5.47), NNH: 5 (4-6); for events that altered cognitive function, 4.46 (2.37-8.37), NNH: 8 (6-12).. Currently available evidence suggests that cannabis treatment is moderately efficacious for treatment of chronic pain, but beneficial effects may be partially (or completely) offset by potentially serious harms. More evidence from larger, well-designed trials is needed to clarify the true balance of benefits to harms.

Cannabis is the most widely consumed illicit drug in the United States. Its use, particularly in early initiates, is associated with subsequent development of other drug and alcohol use disorders.. The authors examined the prevalence of cannabis use and the association between cannabis use and aberrant opioid-related behaviors in patients prescribed chronic opioid therapy for persistent pain.. PubMed was queried for studies of chronic opioid therapy in which aberrant opioid-related behaviors were quantitatively examined and in which cannabis use data (as determined by cannabinoid-positive urine drug tests) were extricable from that of other substances of abuse.. The prevalence of cannabis use among patients prescribed chronic opioid therapy in these studies ranged from 6.2% to 39%, compared with 5.8% in the general United States population. Furthermore, cannabis use in chronic opioid patients shows statistically significant associations with present and future aberrant opioid-related behaviors.. Cannabis use is prevalent in patients prescribed chronic opioid therapy and is associated with opioid misuse. Further research is necessary to clarify the strength and the nature of the association between cannabis use and opioid misuse, and to address additional questions about the consequences of cannabis use in the context of chronic opioid therapy.

Marijuana is the most commonly used illegal drug in the United States and is considered by young adults to be the illicit drug with the least risk. On the other hand, marijuana smoke contains several of the same carcinogens and co-carcinogens as the tar from tobacco, raising concerns that smoking of marijuana may be a risk factor for tobacco-related cancers. We reviewed two cohort studies and 14 case-control studies with assessment of the association of marijuana use and cancer risk. In the cohort studies, increased risks of lung or colorectal cancer due to marijuana smoking were not observed, but increased risks of prostate and cervical cancers among non-tobacco smokers, as well as adult-onset glioma among tobacco and non-tobacco smokers, were observed. The 14 case-control studies included four studies on head and neck cancers, two studies on lung cancer, two studies on non-Hodgkin's lymphoma, one study on anal cancer, one study on penile cancer, and four studies on childhood cancers with assessment of parental exposures. Zhang and colleagues reported that marijuana use may increase risk of head and neck cancers in a hospital-based case-control study in the United States, with dose-response relations for both frequency and duration of use. However, Rosenblatt and co-workers reported no association between oral cancer and marijuana use in a population-based case-control study. An eightfold increase in risk among marijuana users was observed in a lung cancer study in Tunisia. However, there was no assessment of the dose response, and marijuana may have been mixed with tobacco. Parental marijuana use during gestation was associated with increased risks of childhood leukemia, astrocytoma, and rhabdomyosarcoma, but dose-response relations were not assessed. In summary, sufficient studies are not available to adequately evaluate marijuana impact on cancer risk. Several limitations of previous studies include possible underreporting where marijuana use is illegal, small sample sizes, and too few heavy marijuana users in the study sample. Recommendations for future studies are to (1) focus on tobacco-related cancer sites; (2) obtain detailed marijuana exposure assessment, including frequency, duration, and amount of personal use as well as mode of use (smoked in a cigarette, pipe, or bong; taken orally); (3) adjust for tobacco smoking and conduct analyses on nonusers of tobacco; and (4) conduct larger studies, meta-analyses, or pooled analyses to maximize statis

The possible medicinal use of cannabinoids for chronic diseases emphasizes the need to understand the long-term effects of these compounds on the central nervous system. We provide a quantitative synthesis of empirical research pertaining to the non-acute (residual) effects of cannabis on the neurocognitive performance of adult human subjects. Out of 1,014 studies retrieved using a thorough search strategy, only 11 studies met essential a priori inclusion criteria, providing data for a total of 623 cannabis users and 409 non- or minimal users. Neuropsychological results were grouped into 8 ability domains, and effect sizes were calculated by domain for each study individually, and combined for the full set of studies. Using slightly liberalized criteria, an additional four studies were included in a second analysis, bringing the total number of subjects to 1,188 (i.e., 704 cannabis users and 484 non-users). With the exception of both the learning and forgetting domains, effect size confidence intervals for the remaining 6 domains included zero, suggesting a lack of effect. Few studies on the non-acute neurocognitive effects of cannabis meet current research standards; nevertheless, our results indicate that there might be decrements in the ability to learn and remember new information in chronic users, whereas other cognitive abilities are unaffected. However, from a neurocognitive standpoint, the small magnitude of these effect sizes suggests that if cannabis compounds are found to have therapeutic value, they may have an acceptable margin of safety under the more limited conditions of exposure that would likely obtain in a medical setting.

The present study aimed to assess the prevalence of symptoms of anxiety and depression among health professionals in the three most affected regions in Cameroon.. The study was a descriptive cross-sectional type. Participants were health care professionals working in the three chosen regions of Cameroon. The non_probability convinient sample technique and that of the snowball were valued via a web questionnaire. The non-exhaustive sample size was 292. The diagnosis of anxiety and depression was made by the HAD (Hospital Anxiety and Depression scale).. Les auteurs rapportent que le secteur médical est classé à un plus grand risque de contracter le COVID-19 et de le propager potentiellement à d’autres. Le nombre sans cesse croissant de cas confirmés et suspects, la pression dans les soins, l’épuisement des équipements de protection individuelle et le manque de médicaments spécifiques peuvent contribuer à un vécu anxio-dépressif significatif. La présente étude s’est donnée pour ambition d’évaluer la prévalence des symptômes de l’anxiété et de la dépression chez les professionnels de santé dans les trois Régions les plus concernées au Cameroun.. Le choix des trois Régions du Cameroun se justifie non seulement par le fait qu’elles totalisent 95,8 % des cas de coronavirus au pays depuis le début de la pandémie, mais aussi parce qu’elles disposent de plus de la moitié des personnels de santé (56 %). Il s’agit d’une étude transversale, descriptive et analytique. Les participants sont des professionnels de la santé en service dans les Régions du Centre, Littoral et de l’Ouest du Cameroun. La méthode d’échantillonnage non probabiliste de convenance couplée à celle de boule de neige via un web questionnaire a été adoptée. La collecte des données a duré du 5 au 19 avril 2020, intervalle de temps après lequel on n’avait plus eu de répondants. À la fin de cette période, la taille de l’échantillon non exhaustive était de 292 professionnels. Le diagnostic de l’état anxio-dépressive était posé via l’échelle de HAD (Hospital Anxiety and Depression scale). Dans le HAD, chaque réponse cotée évalue de manière semi-quantitative l’intensité du symptôme au cours de la semaine écoulée. Un score total est obtenu ainsi que des scores aux deux sous-échelles : le score maximal est de 42 pour l’échelle globale et de 21 pour chacune des sous-échelles. Le coefficient alpha de Cronbach est de 0,70 pour la dépression et de 0,74 pour l’anxiété. Certains auteurs après plusieurs travaux ont proposé qu’une note inférieure ou égale à 7 indique une absence d’anxiété ou de dépression ; celle comprise entre 8 et 10 suggère une anxiété ou une dépression faible à bénigne ; entre 11 et 14, pour une anxiété ou une dépression modérée ; enfin, une note comprise entre 15 et 21 est révélatrice d’une anxiété sévère.

In primary prevention ICD indication patients, plasma big ET-1 levels can predict VAs and end-stage events and may facilitate ICD-implantation risk stratification.. Beyond age, cognitive impairment was associated with prior MI/stroke, higher hsCRP, statin use, less education, lower eGFR, BMI and LVEF.. These data demonstrate that even a short period of detraining is harmful for elderly women who regularly participate in a program of strength training, since it impairs physical performance, insulin sensitivity and cholesterol metabolism.. Exposure to PM. Respiratory sinus arrhythmia is reduced after PVI in patients with paroxysmal AF. Our findings suggest that this is related to a decrease in cardiac vagal tone. Whether and how this affects the clinical outcome including exercise capacity need to be determined.. BDNF and leptin were not associated with weight. We found that miR-214-5p exerted a protective role in I/R injured cardiac cells by direct targeting FASLG. The results indicated that the MGO injection reduced all CCl. The hepatoprotective effects of MGO might be due to histopathological suppression and inflammation inhibition in the liver.. OVEO showed moderate antifungal activity, whereas its main components carvacrol and thymol have great application potential as natural fungicides or lead compounds for commercial fungicides in preventing and controlling plant diseases caused by. PF trajectories were mainly related to income, pregestational BMI, birth weight, hospitalisation due to respiratory diseases in childhood, participant's BMI, report of wheezing, medical diagnosis and family history of asthma, gestational exposure to tobacco and current smoking status in adolescence and young adult age.. In chronic pain patients on opioids, administration of certain benzodiazepine sedatives induced a mild respiratory depression but paradoxically reduced sleep apnoea risk and severity by increasing the respiratory arousal threshold.. Quantitative measurements of sensory disturbances using the PainVision. The serum level of 20S-proteasome may be a useful marker for disease activity in AAV.. The electrophysiological data and MD simulations collectively suggest a crucial role of the interactions between the HA helix and S4-S5 linker in the apparent Ca.

There is little guidance regarding the impact of alcohol and cannabis on the clinical course of inflammatory bowel disease. The aim of this study was to assess the prevalence, sociodemographic characteristics and impact of alcohol and cannabis use on the clinical course of the disease.. We performed an analysis of prospectively collected data within the Swiss Inflammatory Bowel Disease Cohort Study with yearly follow-ups and substance-specific questionnaires. We analyzed the prevalence of use, the profile of users at risk for addiction and the impact of alcohol and cannabis on the course of the disease.. We collected data of 2828 patients included between 2006 and 2018 and analyzed it according to their completion of specific surveys on alcohol and cannabis use. The prevalence of patient-reported active use was 41.3% for alcohol and 6% for cannabis. Heavy drinkers were over-represented among retired, married smokers receiving mostly aminosalicylates and less immunosuppression. In ulcerative colitis patients, low-to-moderate drinking was associated with less extensive disease. Cannabis users were often students with ileal Crohn's disease.. A significant proportion of patients with inflammatory bowel disease consume alcohol or cannabis. Heavy alcohol consumption is most likely in male smokers >50 years, whereas young men with ileal disease rather use cannabis.

Research on cannabis-related health outcomes in diverse older adults is limited. The current study utilized a matched cohort study design to compare older adults in Hawai'i with identified cannabis diagnoses and matched controls on chronic health conditions, acute health events, and healthcare utilization from 2016 to 2020.. Patients age 50 + were identified using ICD-10 diagnostic codes for cannabis use, abuse, and dependence using electronic health record data from an integrated health system (Kaiser Permanente Hawai'i). Those with cannabis diagnoses (n = 275) were compared to matched non-using controls (n = 275; based on age, sex) on chronic health conditions (coronary heart disease, hypertension, COPD, chronic non-cancer pain), acute health events (myocardial infarction, respiratory symptoms, stroke, persistent or cyclic vomiting, injuries), and healthcare utilization (outpatient, inpatient, and emergency department visits) following case identification for two years.. Participants were 19.3% Native Hawaiian/Pacific Islander, 24.4% Asian, 47.8% White, and 8.5% Other/Unknown, with an average age of 62.8 years (SD=7.3). Adjusting for covariates as possible, participants with a cannabis diagnosis had significantly greater risk of coronary heart disease, chronic non-cancer pain, stroke, myocardial infarction, cyclic vomiting, and injuries, over time, compared to controls. Cannabis use was associated with any and greater frequency of outpatient, inpatient, and emergency department visits.. In a diverse sample, older adults who used cannabis had worse health conditions and events and used more health services over a two-year period. Future studies should evaluate cannabis-related health outcomes, effects of cannabis problem severity, as well as implications for healthcare in aging populations.

It is known from medical practise that patients and physicians can have positive experiences with little-researched and unapproved interventions. Under certain circumstances, effects even go beyond the placebo effect.. Based on casuistics of chronic pain patients, the question of whether self-medication in the context of a good doctor-patient relationship can optimize the efficacy of cannabinoids and reduce dose and undesirable side effects is investigated. Using medicinal cannabis as an example, a new view on self-medication and medical support is proposed.. The casuistics show that daily requirements (average of approximately 75 mg) for Δ. If the patient has "discovered" cannabis as medicine for himself and can draw on positive experiences, something very powerful can emerge. In addition to the specific effects demonstrated by studies, there are non-specific effects or contextual factors at work that tend to be neglected in evidence-based medicine. These non-specific effects include, above all, those factors through which a patient gives a (subjective) meaning to a specific intervention. A new view on self-medication and medical support in chronic diseases is needed.. Hintergrund: Erfahrungsmedizinisch bekannt ist, dass Patienten und Ärzte positive Erfahrungen mit nur wenig erforschten und nicht zugelassenen Interventionen machen können. Dabei gehen Wirkungen unter bestimmten Umständen über den Placeboeffekt hinaus.. Ausgehend von Kasuistiken chronischer Schmerzpatienten wird der Frage nachgegangen, ob durch Selbstmedikation im Kontext einer vertrauensvollen Arzt-Patienten-Beziehung die Wirksamkeit von Cannabinoiden optimiert werden kann und sich Dosis sowie unerwünschte Nebenwirkungen reduzieren lassen. Am Beispiel von Medizinalcannabis wird eine neue Sicht auf Selbstmedikation und ärztliche Begleitung vorgeschlagen.Ergebnisse: Die Erfahrungen aus den Kasuistiken zeigen, dass sich der tägliche Bedarf (durchschnittlich ca. 75 mg) an Tetrahydrocannabinol(THC)-Dosen reduzieren lässt. Eine unbegleitete und risikoreiche Selbstmedikation kann in eine effektive Therapie mit deutlich weniger Medizinalcannabis transformiert werden. Die Vorgehensweise besteht darin, die bis dato stattgefundene Selbstmedikation nachzuvollziehen und den Patienten dort abzuholen, wo er selber für sich etwas "entdeckt" hat. Erklären lässt sich die spezifische Wirkweise von Cannabis bei chronischen Erkrankungen über die Mechanismen im Endocannabinoidsystem. Cannabinoide entlasten Patienten im Kontext von Stress, Angst und Depression, die bei chronischen Erkrankungen immer beteiligt sind. In ihrem körperlichen sowie psychischen Empfinden werden Patienten gestärkt und schließlich in die Selbstwirksamkeit geführt.Schlussfolgerungen: Hat der Patient "Cannabis als Medizin" selbst für sich "entdeckt" und kann auf positive Erfahrungen zurückgreifen, so kann etwas sehr Wirkmächtiges entstehen. Neben den spezifischen Effekten, die durch Studien nachgewiesen werden, wirken unspezifische Effekte bzw. Kontextfaktoren, die in der evidenzbasierten Medizin eher vernachlässigt werden. Zu diesen unspezifischen Effekten gehören vor allem solche Faktoren, durch die ein Patient einem Wirkmittel eine (subjektive) Bedeutung gibt. Eine neue Sicht auf Selbstmedikation und ärztliche Begleitung bei chronischen Erkrankungen ist erforderlich.Schlüsselwörter: Cannabinoide, Selbstmedikation, Endocannabinoidsystem, Placeboanalgesie, ValeboEingereicht am 12.8.2021 - Revision akzeptiert am 17.1.2022.

The number of patients using cannabis for therapeutic purposes is growing worldwide. While research regarding the treatment of certain diseases/disorders with cannabis and cannabinoids is also expanding, only a few longitudinal studies have assessed the mid-term impacts of medical cannabis use on psychological variables and quality of life (QoL). The aim of the study was to assess the psychological safety and QoL of patients with chronic diseases who self-medicate with cannabis over time. We recruited patients with various chronic diseases who use cannabis and collected data regarding patterns of cannabis use as well as mental health, personality and QoL. Participants were followed-up at baseline, 4, 8 and 12 months. Hair analysis was conducted to confirm the presence of cannabinoids. Personality assessment showed a consistent decrease in self-transcendence and self-directedness scores. Neither cognitive nor psychopathological deterioration was found. There were also no variations in QoL. Mid-term use of medical cannabis seems to show adequate tolerability regarding cognitive and psychopathological abilities, and it may help patients with chronic diseases to maintain an acceptable QoL.

Many anti-nausea treatments are available for chronic gastrointestinal syndromes, but data on efficacy and comparative effectiveness are sparse.. To conduct a sectional survey study of patients with chronic nausea to assess comparative effectiveness of commonly used anti-nausea treatments.. Outpatients at a single center presenting for gastroenterology evaluation were asked to rate anti-nausea efficacy on a scale of 0 (no efficacy) to 5 (very effective) of 29 commonly used anti-nausea treatments and provide other information about their symptoms. Additional information was collected from the patients' chart. The primary outcome was to determine which treatments were better or worse than average using a t test. The secondary outcome was to assess differential response by individual patient characteristics using multiple linear regression.. One hundred and fifty-three patients completed the survey. The mean efficacy score of all anti-nausea treatments evaluated was 1.73. After adjustment, three treatments had scores statically higher than the mean, including marijuana (2.75, p < 0.0001), ondansetron (2.64, p < 0.0001), and promethazine (2.46, p < 0.0001). Several treatments, including many neuromodulators, complementary and alternative treatments, erythromycin, and diphenhydramine had scores statistically below average. Patients with more severe nausea responded better to marijuana (p = 0.036) and diphenhydramine (p < 0.001) and less so to metoclopramide (p = 0.020). There was otherwise no significant differential response by age, gender, nausea localization, underlying gastrointestinal cause of nausea, and GCSI.. When treating nausea in patients with chronic gastrointestinal syndromes, clinicians may consider trying higher performing treatments first, and forgoing lower performing treatments. Further prospective research is needed, particularly with respect to highly effective treatments.

Some research suggests that marijuana use facilitates an anti-inflammatory response, yet the relationship between marijuana use and inflammation, as measured by C-reactive protein (CRP), remains poorly understood. The present study examined the association between recency of marijuana use and serum C-reactive protein levels in a nationally representative sample of adults.. Data from Waves III and IV (N = 13,166) of the National Longitudinal Study of Adolescent to Adult Health was utilized. Past 30 day marijuana use was assessed in Waves III and IV, and past year marijuana use was also assessed at Wave IV. CRP was dichotomized with a cutpoint of 3 mg/L. Logistic regression analyses examined the association between marijuana use and CRP levels at Wave IV.. Past 30 day marijuana use was reported by 23.5% and 17.7% of participants at Wave III and Wave IV respectively, and 23.6% of participants reported past year marijuana use during Wave IV. Marijuana use was associated with lower CRP levels in bivariate analyses. However, these associations attenuated after adjusting for sociodemographic and health-related covariates.. Though marijuana and lower CRP levels were initially associated, the effect of marijuana use on CRP was later explained by gender, BMI, and anti-inflammatory medication use. This suggests that marijuana use does not confer an anti-inflammatory effect and recency of use is not relevant. Given expanding marijuana use legislation and discourse surrounding the consequences of marijuana for health, continued research is needed to elucidate the effect of marijuana on inflammation and subsequent risk of chronic disease.

Given a rapidly changing policy landscape, we sought to characterize the effects of state marijuana laws on parents' views of marijuana use by their teenage children.. Data are from 595 respondents to a nationally administered, web-based survey of parents of adolescents (ages 13-18 years) with any of three chronic conditions (type 1 diabetes, rheumatic disease, attention-deficit/hyperactivity disorder). Multivariate ordinal logistic regression was used to model the effects of parents' reports of state cannabis laws on their views toward marijuana use by their child.. While 89.9% said any marijuana use was risky for their child, 27.9% would approve of its use if prescribed as medicine. Parents reporting marijuana decriminalization (11.1%) were more amenable to teenage use, less concerned about how marijuana might impact their child's condition, more accepting of the safety of marijuana as medicine, and approved its use with a prescription. Parents reporting legal medical (35.6%) or recreational (5.7%) use were more likely to report that their child has tried or used marijuana regularly. Parents reporting legal recreational use were less likely to agree that marijuana has medical benefits for their child.. Among parents of medically vulnerable children, perceiving state marijuana policies as more permissive is strongly associated with lower perceived riskiness of marijuana use for their children. State marijuana policies are changing with implications for how parents of medically vulnerable youth view and potentially govern marijuana use by their medically vulnerable children.

Cannabis use is associated with the development of psychotic symptoms and increased risk for schizophrenia. The mismatch negativity (MMN) is a brain event-related potential marker of change detection thought to index glutamatergic N-methyl-D-aspartate receptor-mediated neurotransmission, which is known to be deficient in schizophrenia. This study examined auditory MMN in otherwise healthy chronic cannabis users compared with nonuser control subjects.. Forty-two chronic cannabis users and 44 nonuser healthy control subjects completed a multi-feature MMN paradigm, which included duration, frequency, and intensity deviants (deviants 6%; standards 82%). The MMN was compared between users and control subjects as well as between long- and short-term users and age- and gender-matched control subjects. Associations between MMN, cannabis use measures, and symptoms were examined.. The MMN amplitude was significantly reduced to frequency but not duration or intensity deviants in overall cannabis users relative to control subjects. Frequency MMN was similarly attenuated in short- and long-term users relative to control subjects. Long-term users also exhibited reduced duration MMN relative to control subjects and short-term users and this was correlated with increased duration of exposure to cannabis and increased psychotic-like experiences during intoxication. In short-term users, a younger age of onset of regular cannabis use and greater frequency of use were associated with greater psychotic-like experiences and symptomatic distress.. These results suggest impaired sensory memory that might reflect N-methyl-D-aspartate receptor dysfunction in chronic cannabis users. The pattern of MMN alterations in cannabis users differed from that typically observed in patients with schizophrenia, indicating overlapping but distinct underlying pathology.

Despite its increasing prevalence and acceptance among the general public, cannabis use continues to be viewed as an aberrant activity in many contexts. However, little is known about how stigma associated with cannabis use affects individuals who use cannabis for therapeutic purposes (CTP) and what strategies these individuals employ to manage associated stigma. The aim of this Canadian study was to describe users' perceptions of and responses to the stigma attached to using CTP.. Twenty-three individuals who were using CTP for a range of health problems took part in semi-structured interviews. Transcribed data were analyzed using an inductive approach and comparative strategies to explore participants' perceptions of CTP and identify themes.. Participant experiences of stigma were related to negative views of cannabis as a recreational drug, the current criminal sanctions associated with cannabis use, and using cannabis in the context of stigmatizing vulnerability (related to existing illness and disability). Strategies for managing the resulting stigma of using CTP included: keeping CTP 'undercover'; educating those who did not approve of or understand CTP use; and using cannabis responsibly.. Understanding how individuals perceive and respond to stigma can inform the development of strategies aimed at reducing stigma associated with the use of CTP and thereby address barriers faced by those using this medicine.

To characterize health-related quality of life (HRQoL) in medical cannabis patients.. Short Form 36 (SF-36) Physical Health Component Score and Mental Health Component Score (MCS) surveys as well has CDC (Centers for Disease Control) HRQoL-14 surveys were completed by 37 qualified patients.. Mean SF-36 PCS and MCS, normalized at 50, were 37.4 and 44.2, respectively. Eighty percent of participants reported activity/functional limitations secondary to impairments or health problems. Patients reported using medical cannabis to treat a wide array of symptoms across multiple body systems with relief ratings consistently in the 7-10/10 range.. The HRQoL results in this sample of medical cannabis-using patients are comparable with published norms in other chronically ill populations. Data presented provide insight into medical cannabis-using patients' self-rated health, HRQoL, disease incidences, and cannabis-related symptom relief.

Given the hypothesised association between cannabis use and schizophrenia, and the well documented alterations in pre-pulse inhibition (PPI) that are observed in schizophrenia, it is of interest to examine the effects of cannabis use on PPI.. The objective of the study was to use novel methodology for the measurement and characterisation of attentional modulation of PPI, in order to examine the nature of PPI in chronic cannabis users.. PPI was measured in 34 chronic cannabis users (who were otherwise healthy) and 32 healthy controls, across a range of startling stimulus intensities, during two attention set conditions, one in which they were instructed to attend to the auditory stimuli and one in which they were instructed to ignore the auditory stimuli and focus on a visual task. Curves of best fit were fitted to the startle magnitudes, across the stimulus intensities. A number of reflex parameters were extracted from these logistic functions, each of which reflects a different characteristic of the startle response.. Cannabis users failed to show attentional modulation of any of the reflex parameters and showed altered PPI, relative to controls, but only when they were instructed to sustain attention to the auditory stimuli.. Cannabis users showed an attention-dependant alteration in PPI, which appeared to reflect a deficit in sustain attention, and which was different to that which has been observed in schizophrenia using the same methodology.

Cannabidiol, the major psycho-inactive component of cannabis, has substantial anti-inflammatory and immunomodulatory effects. This study investigated its therapeutic potential on neuropathic (sciatic nerve chronic constriction) and inflammatory pain (complete Freund's adjuvant intraplantar injection) in rats. In both models, daily oral treatment with cannabidiol (2.5-20 mg/kg to neuropathic and 20 mg/kg to adjuvant-injected rats) from day 7 to day 14 after the injury, or intraplantar injection, reduced hyperalgesia to thermal and mechanical stimuli. In the neuropathic animals, the anti-hyperalgesic effect of cannabidiol (20 mg/kg) was prevented by the vanilloid antagonist capsazepine (10 mg/kg, i.p.), but not by cannabinoid receptor antagonists. Cannabidiol's activity was associated with a reduction in the content of several mediators, such as prostaglandin E(2) (PGE(2)), lipid peroxide and nitric oxide (NO), and in the over-activity of glutathione-related enzymes. Cannabidiol only reduced the over-expression of constitutive endothelial NO synthase (NOS), without significantly affecting the inducible form (iNOS) in inflamed paw tissues. Cannabidiol had no effect on neuronal and iNOS isoforms in injured sciatic nerve. The compound's efficacy on neuropathic pain was not accompanied by any reduction in nuclear factor-kappaB (NF-kappaB) activation and tumor necrosis factor alpha (TNFalpha) content. The results indicate a potential for therapeutic use of cannabidiol in chronic painful states.

The Canadian Marihuana Medical Access Regulations (MMAR) program allows Health Canada to grant access to marihuana for medical use to those who are suffering from grave and debilitating illnesses. This is a report on a case series of 30 patients followed at a tertiary care pain management center in Nova Scotia who have used medicinal marihuana for 1-5 years under the MMAR program. Patients completed a follow-up questionnaire containing demographic and dosing information, a series of 11-point numerical symptom relief rating scales, a side effect checklist, and a subjective measure of improvement in function. Doses of marihuana ranged from less than 1 to 5g per day via the smoked or oral route of administration. Ninety-three percent of patients reported moderate or greater pain relief. Side effects were reported by 76% of patients, the most common of which were increased appetite and a sense of well-being, weight gain, and slowed thoughts. Limitations of the study include self-selection bias, small size, and lack of a control group. The need for further study using controlled trials is discussed along with an overview of the MMAR program.

The use of cannabis for medical purposes is a controversial but an important topic of public and scientific interest. We report on the results of a self-administered questionnaire study conducted in the United Kingdom between 1998 and 2002. The questionnaire consisted of 34 items and included demographic data, disease and medication use patterns and cannabis use profiles. Subjects were self-selected; 3663 questionnaires were distributed and 2969 were returned [1805 (60.9%) women, mean age 52.7 years (SD 12.7)]. Medicinal cannabis use was reported by patients with chronic pain (25%), multiple sclerosis and depression (22% each), arthritis (21%) and neuropathy (19%). Medicinal cannabis use was associated with younger age, male gender and previous recreational use (p < 0.001). While caution must be exercised in interpreting these data, they point to the need for clinical studies of cannabis and cannabinoids with standardised and quality-controlled products.

Prior to 2002, few clinical data were available to indicate whether cannabis extracts may be beneficial. However, in the last two years, results of several placebo-controlled clinical trials of orally administered compounds have been published, and these cast doubt on the efficacy of delta9-tetrahydrocannabinol (delta9-THC) in objectively reducing spasticity in MS. By contrast, it has been claimed that sublingually administered cannabis extracts that contain approximately equal concentrations of delta9-THC and cannabidiol, a natural cannabinoid that does not act on the CB1 receptor, can produce a statistically and clinically significant reduction in spasticity, although this claim has yet to be thoroughly validated. Nonetheless, results of preclinical trials also lend support to the hypothesis that the endogenous cannabinoid system may be involved in the regulation of spasticity and pain. A better indication of the clinical potential of the different cannabis extracts will have to await the publication of the most recent clinical trial data. This review critically evaluates the most recent evidence available on the potential use of medicinal extracts of cannabis to relieve pain and spasticity in multiple sclerosis.

There has been a surge in interest in medicinal cannabis in Canada. We conducted a questionnaire survey to determine the current prevalence of medicinal cannabis use among patients with chronic non-cancer pain, to estimate the dose size and frequency of cannabis use, and to describe the main symptoms for which relief was being sought. Over a 6-week period in mid-2001, 209 chronic non-cancer pain patients were recruited in an anonymous cross-sectional survey. Seventy-two (35%) subjects reported ever having used cannabis. Thirty-two (15%) subjects reported having used cannabis for pain relief (pain users), and 20 (10%) subjects were currently using cannabis for pain relief. Thirty-eight subjects denied using cannabis for pain relief (recreational users). Compared to never users, pain users were significantly younger (P=0.001) and were more likely to be tobacco users (P=0.0001). The largest group of patients using cannabis had pain caused by trauma and/or surgery (51%), and the site of pain was predominantly neck/upper body and myofascial (68% and 65%, respectively). The median duration of pain was similar in both pain users and recreational users (8 vs. 7 years; P=0.7). There was a wide range of amounts and frequency of cannabis use. Of the 32 subjects who used cannabis for pain, 17 (53%) used four puffs or less at each dosing interval, eight (25%) smoked a whole cannabis cigarette (joint) and four (12%) smoked more than one joint. Seven (22%) of these subjects used cannabis more than once daily, five (16%) used it daily, eight (25%) used it weekly and nine (28%) used it rarely. Pain, sleep and mood were most frequently reported as improving with cannabis use, and 'high' and dry mouth were the most commonly reported side effects. We conclude that cannabis use is prevalent among the chronic non-cancer pain population, for a wide range of symptoms, with considerable variability in the amounts used. Discussions between patients and health care providers concerning cannabis use may facilitate education and follow up, and would allow side effects and potential interactions with other medications to be monitored. Clinical trials of cannabis for chronic non-cancer pain are warranted.

Health Canada finally produces a good marijuana crop, but its medical marijuana program is in a state of upheaval as it faces internal dissent regarding a crucial aspect of its mandate, as well as fundamental challenges from the courts. Meanwhile, the Justice Minister said that the government will introduce legislation to decriminalize the possession of small amounts of marijuana.

Excitotoxicity is a paradigm used to explain the biochemical events in both acute neuronal damage and in slowly progressive, neurodegenerative diseases. Here, we show in a longitudinal magnetic resonance imaging study that Delta(9)-tetrahydrocannabinol (Delta(9)-THC), the main active compound in marijuana, reduces neuronal injury in neonatal rats injected intracerebrally with the Na(+)/K(+)-ATPase inhibitor ouabain to elicit excitotoxicity. In the acute phase Delta(9)-THC reduced the volume of cytotoxic edema by 22%. After 7 d, 36% less neuronal damage was observed in treated rats compared with control animals. Coadministration of the CB(1) cannabinoid receptor antagonist SR141716 prevented the neuroprotective actions of Delta(9)-THC, indicating that Delta(9)-THC afforded protection to neurons via the CB(1) receptor. In Delta(9)-THC-treated rats the volume of astrogliotic tissue was 36% smaller. The CB(1) receptor antagonist did not block this effect. These results provide evidence that the cannabinoid system can serve to protect the brain against neurodegeneration.

Establishment of residual cognitive and psychotic effects (effects present at the time that all active cannabinoids are eliminated from the body) putatively produced by prolonged heavy cannabis use is difficult, because of many confounding variables like slow elimination of active cannabinoids, lack of supervision during abstinence, poor use of well-matched control groups and the presence of withdrawal symptoms. Residual cognitive effects were observed in some but not in all tests after prolonged heavy cannabis use. The effects were mostly mild. The relationship of cannabis use, psychotic effects and schizophrenia was unclear; the cannabis conceivably gave relief, but it also appeared that cannabis caused schizophrenia in young people and (or) enhanced the symptoms, especially in young people poorly able to cope with stress or in whom the antipsychotic therapy was unsuccessful.

In a follow-up study the prevalence of chronic respiratory symptoms and changes in ventilatory capacity were followed over a period of three years in 38 female and 28 male hemp workers in a textile industry. The prevalence of all respiratory symptoms was found to be increased. Significant acute reductions of ventilatory capacity were recorded during the work shift. The measured ventilatory capacity values were significantly decreased in comparison to predicted normal values. The mean annual decline of FVC (range: 0.014-0.065 L), FEV1 (range: 0.041-0.068 L), FEF50 (range: 0.020-0.220 L/s) and FEF25 (range: 0.030-0.140 L/s) was considerably greater than in healthy non-exposed subjects. The mean annual decline of all tests was considerably larger in workers with the symptoms of byssinosis than in those without such symptoms. Our data suggest that long-term exposure to hemp dust may cause the development of chronic respiratory symptoms and impairment of ventilatory capacity.

Acute and chronic psychotic states in juvenile drug addicts demand careful observation of syndrome-genetic and differential diagnostic factors. Not only the diagnosis of a schizophrenic or affective juvenile psychosis and their differentiation from phase-specific developmental crises may often be difficult. A further problematic field are special aspects of symptomatic psychoses and particularly states due to drug addiction with hashish, LSD and amphetamines and the effect of drugs on already existing endogenous psychoses. This demands subtile phenomenologic description and syndrome-genetic assessment. One will have to take into account the complexity of drug effects and whether a psychosis existed already before addiction, whether drugs have provoked a latent psychosis, whether a purely symptomatic psychosis mimics a schizophrenia or whether irreversible personality changes with secondary psychotic behavior have developed.

The authors compared 47 long-term users of hashish with a control group of 40 subjects matched for age, ethnic origin, education, etc., in order to determine whether they differed significantly on psychiatric, physical health, and demographic variables. There was a significantly higher incidence of personality disorders, unemployment, and prison sentences in the group of chronic users. However, in contrast to the findings of other researchers, the hashish users did not have organic psychoses, nor did they differ from control subjects in neurologic signs or EEG and echo encephalogram patterns.

Chronic cannabis intoxication of a significant fraction of the male population still prevails in Morocco. The preparation used (kif) is a powder made from the dried flower of the female plant. It contains 2 to 3% THC and is smoked mixed with tobacco (1/3 of the mixture). Cultivation of kif is tolerated in an area of 60 square miles in the high Rif mountain of Northern Morocco, where it constitutes the main cash crop of the local farmers. A significant percentage (50%?) of the men in the area also consume kif regularly. This cultivation is spreading to neighboring areas. Moroccan health authorities claim that cannabis intoxication represents a major health hazard. There exist little data correlating chronic usage of kif with pathological states in these areas of large production and consumption. This dearth of information due to lack of local medical personnel could be alleviated by a combined medical and ethnological study.
