Predictors of effective therapy among individuals with Cannabis Use Disorder: a review of the literature.

Treatment demand for Cannabis Use Disorder (CUD) has increased in the past decade in almost all European countries, and CUD is currently the most common reason for first-time drug-related treatment admission in the European Union. Even though several therapeutic approaches have been shown to benefit individuals with CUD, there is a lack of knowledge regarding factors associated with effective therapy and the underlying mechanisms of change among individuals with CUD presenting for treatment. The aim of the present paper was to review current knowledge on factors that have been shown to contribute to positive outcomes in CUD treatment. A scoping methodology was used, focusing on empirically evaluated studies that used defined, cannabis-related outcome measures. In eligible studies, factors of investigation were categorized as either 'mediators', i.e., treatment-related factors associated with the processes or mechanisms through which patients benefit from therapy, or 'moderators' which are patient-related characteristics that predict his/her odds to benefit from treatment or patient-related (i.e., moderators). Factors categorized as mediators were then classified 'specific factors' if they were related to a certain technique or treatment modality or 'common factors' if they were assessed beyond treatment modalities. Findings suggest that in CUD treatment, specific mediators include treatment duration, addressing motivation to change, acquiring coping skills, enhancing self-efficacy, and integrating several therapeutic components. Common mediators include therapeutic alliance, empathy, expectations and cultural adaptation. Moderators in CUD treatment include sex, ethnicity, age-related factors and comorbid disorders.

Cannabis-related treatment demand at the eve of German cannabis legalization - a 20-years trend analysis.

Post-2000, the prevalence of cannabis consumption has been rising internationally. This paper investigates whether cannabis-related treatment demand in German outpatient addiction care facilities (OACFs) has been following this trend. Treatment demand related to cannabis use disorder (CUD) for the period 2001 to 2021 was investigated using data from the nation-wide standardized German Addiction Care Statistical Service. Analyses covered all and first-time treatment admissions, demographics, and treatment outcomes. We identified years with significant changes in slope or direction of trends through joinpoint regression. Trends within the CUD client population were contrasted with trends among the entire OACF client population. CUD is the second-most common cause for OACF admissions in Germany. Between 2001 and 2021, the share of CUD-related cases among total OACF caseload increased from 7.1 to 19.9%, whereby the share of first-time treatment admissions declined from 79.6 to 55.6%. The share of CUD client population > 35 years almost tripled from 6.0 to 17.4%, that of female client population rose from 15.6 to 18.1%. From 2001 to 2007, the share of CUD-related treatments completed with improved symptomatology increased from 54.7 to 65.6%, followed by a marginal decline. CUD-related treatment demand is growing in Germany's OACFs, involving a client population that is increasingly older and more experienced with the addiction care system. As current intervention programmes mainly target adolescents and young adults who have been consuming cannabis only for a short time, adapting service offers to the changing client profiles appears paramount to improve treatment effectiveness.

Clinical practice guidelines for enhanced recovery after colon and rectal surgery from the American Society of Colon and Rectal Surgeons and the Society of American Gastrointestinal and Endoscopic Surgeons.

The American Society of Colon and Rectal Surgeons (ASCRS) and the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) are dedicated to ensuring high-quality innovative patient care for surgical patients by advancing the science, prevention, and management of disorders and diseases of the colon, rectum, and anus as well as minimally invasive surgery. The ASCRS and SAGES society members involved in the creation of these guidelines were chosen because they have demonstrated expertise in the specialty of colon and rectal surgery and enhanced recovery. This consensus document was created to lead international efforts in defining quality care for conditions related to the colon, rectum, and anus and develop clinical practice guidelines based on the best available evidence. While not proscriptive, these guidelines provide information on which decisions can be made and do not dictate a specific form of treatment. These guidelines are intended for the use of all practitioners, healthcare workers, and patients who desire information about the management of the conditions addressed by the topics covered in these guidelines. These guidelines should not be deemed inclusive of all proper methods of care nor exclusive of methods of care reasonably directed toward obtaining the same results. The ultimate judgment regarding the propriety of any specific procedure must be made by the physician in light of all the circumstances presented by the individual patient. This clinical practice guideline represents a collaborative effort between the American Society of Colon and Rectal Surgeons (ASCRS) and the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and was approved by both societies.

Medical cannabis and stigma: A qualitative study with patients living with chronic pain.

AIMS AND OBJECTIVES: To explore the ways in which stigma is experienced, and what strategies are used to manage stigma among patients using medical cannabis to ease suffering from chronic pain. BACKGROUND: Various jurisdictions have legalised medical cannabis in recent decades. Despite increasing prevalence and more liberal attitudes towards medical cannabis, it is possible that patients who use medical cannabis experience stigma. DESIGN: A phenomenological qualitative study. METHODS: Fifteen patients living with chronic pain and licensed by the Israeli Ministry of Health to use medical cannabis to treat pain symptoms for at least 1 year participated in semi-structured interviews. Transcribed data were analysed using thematic analysis to identify themes related to stigma. The manuscript is in correspondence to SRQR EQUATOR checklist. RESULTS: Expressions of stigma were more related to 'felt' than 'enacted' stigma. Stigma related to decisions to delay onset of medical cannabis treatment and the ways in which participants managed medical cannabis use during their everyday lives. Participants dissociated themselves from recreational cannabis users, by presenting themselves as responsible normative individuals and engaging in a form of normalisation known as 'normification', emphasising their own discrete and controlled medical cannabis use and cannabis' benefits. CONCLUSIONS: Patients experienced 'felt' stigma which had consequences for their self-presentations and medical cannabis use. This suggests that medical cannabis is not normalised in Israel and interventions may be needed to handle stigma related to medical cannabis. RELEVANCE TO CLINICAL PRACTICE: The findings emphasise the effects of 'felt' stigma on patients. Aiming to increase the effectiveness of medical cannabis treatment and reducing harms, we suggest that particular focus should be placed on managing stigma at the intrapersonal level. In addition, there may be a need to address stigma at the societal level including social interactions with friends, family and medical personnel.

Negative experiences of patients using medicinal cannabis: A systematic review of qualitative studies.

AIMS AND OBJECTIVES: In this study, we systematically reviewed qualitative studies concerning patients' experience with medicinal cannabis (MC) use, to gain insight into the negative effects of MC. BACKGROUND: Over the past decades, the use of MC for therapeutic purposes has increased. However, there is conflicting and insufficient data on possible negative physiological and psychological effects of MC treatment. DESIGN: A systematic review was conducted and the PRISMA guidelines were adopted. Literature searches were conducted using PubMed, PsycINFO and EMBASE. Critical Appraisal Skills Programme (CASP) qualitative checklist used to assess risk of bias in the included studies. METHODS: We included studies focusing on conventional medical treatment using cannabis-based products, approved by a physician for a particular health issue. RESULTS: Of the 1230 articles identified in the initial search, eight articles were included in the review. Following the compilation of themes in the eligible studies, six themes were identified: (1) MC approval; (2) administrative barriers; (3) social perception; (4) MC misuse/widespread effect; (5) adverse effects; and (6) dependence or addiction. These were grouped into two meta-themes: (1) administrative and social aspects of MC use; and (2) experiences of the effects of medicinal cannabis. CONCLUSIONS: Our findings call for specific attention to unique consequences associated with MC use. Further research is needed in order to assess the degree to which negative experiences associated with MC use may affect various aspects of patients' medical condition. RELEVANCE TO CLINICAL PRACTICE: Describing the complex experience of MC treatment and its spectrum of consequences for patients may enable physicians, therapists and researchers to provide more attentive and accurate MC treatment to their patients. PATIENT OR PUBLIC CONTRIBUTION: In this review, patients' narratives were explored, yet the research methods did not directly involve patients or the public.

Cannabis and Depression.

There is a growing body of evidence pointing to the co-occurrence of cannabis use and depression. There is also some evidence that the use of cannabis may lead to the onset of depression; however, strong evidence points to the inverse association; i.e. that depression may lead to the onset or increase in cannabis use frequency. Observational and epidemiological studies have not indicated a positive long-term effect of cannabis use on the course and outcome of depression. The association between cannabis use and depression may be stronger among men during adolescence and emerging adulthood and stronger in women during midlife. There is an indication for potential genetic correlation contributing to the comorbidity of cannabis dependence and major depression, namely that serotonin (5-HT) may mediate such association and there is also evidence for specific risk alleles for cannabis addiction. There is preclinical evidence that alteration in the endocannabinoid system could potentially benefit patients suffering from depression. However, the issue of using cannabis as an anti-depressant is at an early stage of examination and there is little evidence to support it. Finally, there has been little support to the notion that selective serotonin reuptake inhibitors (SSRIs) may be effective in decreasing depressive symptoms or rates of substance use in adolescents treated for depression and a co-occurring substance use disorder. In conclusion, despite methodological limitations, research in the past decades has broadened our knowledge on the association between cannabis use and depression from epidemiological, neurological, genetic, and pharmacological perspectives.

Attitudes towards Substance Use Disorders among Students in the Social Sciences: The Role of Gender and Terminology.

Background: Negative attitudes towards individuals with substance use disorders (SUDs) have been consistently reported within the general population, as well as among health professionals and medical students. Objectives: To explore attitudes towards SUDs held by students in the social sciences, the future-to-be mental health professionals, as well as factors, which may affect these attitudes. Methods: Undergraduate and graduate students in the social sciences (psychology, social work, criminology; N = 184), were presented a vignette describing an individual with substance-related problems. Participants were randomly assigned with one of two vignettes, either addressing him as "suffering from substance use disorder" or as an "addict." Attitudes were assessed by exploring the degree to which participants perceive the described individual as posing social threat and in need of treatment. Results: Women generally perceived individuals with SUDs as in more need for treatment compared to men. Men, but not women, were significantly affected by the terminology used, with less negative attitudes reported when using medical terminology. Conclusion: Gender differences in attitudes towards individuals with SUDs may be present in earlier stages of mental health professionals' career. More emphasis should be given on the use of non-stigmatizing terminology among students in the social sciences, particularly men.

Diagnostic Modalities in Gastrointestinal Bleeding.

A variety of diagnostic modalities is available to assist in the evaluation of patients presenting with acute gastrointestinal (GI) bleeding. This article reviews some older technologies like colonoscopy, nuclear scintigraphy, and conventional angiography and will also review the newest additions to the lower GI bleeding diagnostic toolbox, which are video capsule endoscopy and computed tomography (CT) angiography. The management algorithm used at a given institution depends on the available expertise and resources.

Elevation of Serum CEA in Patients with Squamous Cell Carcinoma of the Anus.

The proportion of anal cancer cases that produce elevated carcinoembryonic antigen (CEA) levels is not well described in the medical literature. In this study, we used electronic health record data from a single urban cancer center to identify patients from 2004-2018 with anal cancer who have also had a pre-initial treatment CEA measurement. We identified 40 patients who met our eligibility criteria. Of those, 11 (27.5%) had an elevated pretreatment CEA. Elevated CEA was not associated with any of the clinical or demographic covariates; however, three out of five patients with a recurrence had an elevated CEA.

[MEDICAL MARIJUANA DEPENDENCE AMONG CHRONIC PAIN PATIENTS SUFFERING FROM DEPRESSION AND ANXIETY].

INTRODUCTION: In recent years, medical marijuana (MM) is increasingly being used for the treatment of chronic pain. Depression and anxiety have been identified as risk factors for the problematic use of prescription opioids, yet their contribution to developing MM dependence hasn't been explored up to date. In this study we explored the association between depression and anxiety severity and the risk for cannabis dependence among chronic pain patients prescribed MM. METHODS: Participants were 324 chronic pain patients prescribed MM with no cuncurrent opioid treatment. All participants were screened for depression using the Patient Health Questionnaire (PHQ-9), for anxiety using the Generalized Anxiety Disorder questionnaire (GAD-7) and for problematic use of MM according to DSM-IV criteria for cannabis dependence using the AUDADI-IT questionnaire. Logistic regression analyses controlling for additional sociodemographic and clinical factors were conducted. RESULTS: Generally, prevalence of cannabis dependence was higher among participants with levels of depression and anxiety levels compared to those without depression or anxiety. However, after controlling for confounders only participants with severe depression were significantly more likely (Adjusted Odds Ratio=5.86) to screen positive for cannabis dependence compared to those without depression. CONCLUSIONS: Severe depression may be a risk factor for problematic use of MM among chronic pain patients. Increasing use of MM calls for further explotartion of potential risk factors which may predict problematic MM use among this population.

Clinical and functional outcomes of cannabis use among individuals with anxiety disorders: A 3-year population-based longitudinal study.

BACKGROUND: Cannabis use has been reported to negatively affect the course and outcome of various psychiatric disorders, yet little is known on its effect on rates of remission from anxiety disorders and associated clinical and functional outcomes. METHODS: In this study, data were drawn from Waves 1 and 2 of the National Epidemiologic survey on Alcohol and Related Conditions, focusing on individuals who qualified for a diagnosis of any anxiety disorder (social anxiety, panic disorder, generalized anxiety disorder, and specific phobias) at Wave 1 (N = 3,723). Cannabis users and individuals with cannabis use disorders (CUDs) throughout a 4-year period were compared to nonusers in rates of remission, suicidality, general functioning, and quality of life at Wave 2, while controlling for baseline confounders. RESULTS: Although rates of remission decreased with level of cannabis use, this was not maintained in adjusted models. Aside from specific outcomes (individuals with CUDs were significantly more prone to report breaking up from a romantic relationship; adjusted odds ratio [AOR] = 3.85, 95% confidence interval [CI] = 1.66-8.97) and repeatedly quitting school (AOR = 6.02, 95% CI = 2.65-13.66)), following adjustment no additional differences were found in outcome measures. CONCLUSIONS: These findings add to previous reports suggesting that poorer outcome of anxiety disorders among cannabis users may be attributed mainly to differences in baseline factors and not cannabis use.

Anal canal squamous cell cancer: are surgical alternatives to chemoradiation just as effective?

PURPOSE: The purpose of this paper is to study long-term oncologic outcomes after different treatment strategies for anal canal cancer (SCAC). METHODS: Patients with SCAC (2004-2013) were identified from Surveillance, Epidemiology, and End Results (SEER) database. Patients undergoing radiation (RT) were compared to those undergoing local excision (LE), abdominoperineal resection (APR), and abdominoperineal resection after radiation (RT + APR). Overall survival (OS) and cancer-specific survival (CSS) data were evaluated using Kaplan-Meier and Cox regression. RESULTS: Two thousand seven hundred and seventy-two (83.8%) patients underwent RT, 382 (11.6%) LE, 77 (2.3%) APR, 76 (2.3%) RT + APR. Median age for the four groups was 60, 57, 64, and 56 years and 32, 49.7, 53.2, and 39.5% were male, respectively, while median tumor size was 4.4, 2.6, 5.3, and 5.5 cm, respectively. Five-year OS of RT, LE, APR, and RT + APR groups was 63.7, 79.6, 25.8, and 41.8% while CSS was 79.6, 92.5, 75.6, and 58.8%, respectively, (p < 0.001). Adjusted hazard ratios for OS for LE, APR, and RT + APR with RT as reference were 1.007 (0.702-1.444), 2.311 (1.367-3.906), and 2.072 (1.016-4.228), respectively. CONCLUSION: These data suggest that APR does not provide better outcomes in treatment of SCAC. Chemoradiation remains the gold standard treatment for majority of patients. Local excision is associated with favorable outcomes in some circumstances.
