Cannabis and opioid perceptions, co-use, and substitution among patients across 4 NCI-Designated Cancer Centers.

Prescription opioids are used for managing pain in persons with cancer, however, there are socioeconomic and racial disparities in medication access. Cannabis is increasingly used for cancer symptom management and as an opioid alternative. Limited data are available about patterns of opioid and cannabis use among patients with cancer. We used survey data from 4 National Cancer Institute-designated cancer centers in 3 states (n = 1220) to assess perceptions, use of cannabis and opioids for pain, their substitution, and racial and ethnic differences in each outcome. Compared with White patients, Black patients were less likely to use opioids for pain (odds ratio [OR] = 0.66; P = .035) and more likely to report that cannabis was more effective than opioids (OR = 2.46; P = .03). Race effects were mitigated (P > .05) after controlling for socioeconomic factors. Further research is needed to understand cannabis and opioid use patterns and how overlapping social determinants of health create a disadvantage in cancer symptom management for Black patients.

Behavioural mental health interventions delivered in the emergency department for suicide, overdose and psychosis: a scoping review.

OBJECTIVE: To identify and describe evidence on brief emergency department (ED)-delivered behavioural and care process interventions among patients presenting with suicide attempt or acute ideation, substance overdose or psychosis. DESIGN: We employed a scoping review design and searched multiple data sources, clinical trial registries and references lists through March 2023. We included English-language trials and rigorously designed observational studies. In alignment with scoping review guidelines, we did not assess the quality of included studies or rate the strength of evidence of intervention effectiveness. POPULATION: Our population of interest was adults presenting to the ED with suicidality (eg, attempt or acute ideation), any substance overdose or acute psychosis from a primary mental health condition. INTERVENTION: We included studies of brief behavioural or care process interventions delivered in the ED. OUTCOME MEASURES: Health outcomes (eg, symptom reduction), healthcare utilisation and harms. RESULTS: Our search identified 2034 potentially relevant articles. We included 40 studies: 3 systematic reviews and 39 primary studies. Most studies (n=34) examined ED interventions in patients with suicide attempt or suicidal ideation, while eight studies examined interventions in patients with opioid overdose. No studies examined ED interventions in patients with acute psychosis. Most suicide prevention studies reported that brief psychological, psychosocial or screening and triage interventions reduce suicide and suicide attempt following an ED visit. Most clinical trial interventions were multicomponent and included at least one follow-up. All substance overdose studies focused on opioids. These studies often contained medication and referral or consultation components. Multiple studies reported increases in substance use disorder treatment utilisation; evidence on repeat overdose events was limited. CONCLUSIONS: A wide range of multicomponent ED-delivered behavioural health interventions for suicidality and opioid use disorder show short-term improvement on primary outcomes such as suicide reattempt. Few studies on non-opioid substances and psychosis are available.

Toward reducing racialized pain care disparities: Approaching cannabis research and access through the lens of equity and inclusion.

There is growing interest in cannabis use for cancer pain. This commentary aims to discuss the evidence surrounding cannabis use for cancer pain in the context of the long-racialized landscape of cannabis policies and the disparity in pain control among cancer patients holding minoritized racial identities. Much evidence surrounding both the benefits and harms of cannabis use in cancer patients, and all patients in general, is lacking. Although drawing on the research in cancer that is available, it is also important to illustrate the broader context about how cannabis' deep roots in medical, political, and social history impact patient use and health care policies. There are lessons we can learn from the racialized disparities in opioid risk mitigation strategies, so they are not replicated in the settings of cannabis for cancer symptom management. Additionally, the authors intentionally use the term "cannabis" here rather than "marijuana.: In the early 1900s, the lay press and government popularized the use of the word "marijuana" instead of the more common "cannabis" to tie the drug to anti-Mexican prejudice.

Dispensary Staff Perceptions About the Benefits, Risks, and Safety of Cannabis for Medical Purposes.

BACKGROUND: Therapeutic use of cannabis is common in the United States (up to 18.7% of Americans aged ≥12), and dispensaries in the US are proliferating rapidly. However, the efficacy profile of medical cannabis is unclear, and customers often rely on dispensary staff for purchasing decisions. The objective was to describe cannabis dispensary staff perceptions of medical cannabis benefits and risks, as well as its safety in high-risk populations. METHODS: Online Survey study conducted using Qualtrics from February 13, 2020 to October 2, 2020 with a national sample of dispensary staff who reportedinteracting with customers in a cannabis dispensary selling tetrahydrocannabinol-containing products. Participants were queried about benefits ("helpfulness") and risks ("worry") about cannabis for a variety of medical conditions, and safety in older adults and pregnant women on a five-point Likert scale. These results were then collapsed into three categories including "neutral" (3/5). "I don't know" (uncertainty) was a response option for helpfulness and safety. RESULTS: Participants (n = 434) were from 29 states and included patient-facing dispensary staff (40%); managers (32%); pharmacists (13%); and physicians, nurse practitioners, or physician assistants (5%). Over 80% of participants perceived cannabis as helpful for post-traumatic stress disorder (88.7%), epilepsy (85.3%) and cancer (83.4%). Generally, participants were not concerned about potential cannabis risks, including increased use of illicit drugs (76.3%), decreases in intelligence (74.4%), disrupted sleep (71.7%), and new/worsening health problems from medical cannabis use (70.7%). Cannabis was considered safe in older adults by 81.3% of participants, though there was much less consensus on safety in pregnancy. CONCLUSIONS: Cannabis dispensary staff generally view medical cannabis as beneficial and low-risk. However, improvements in dispensary staff training, an increased role for certifying clinicians, and interventions to reduce dispensary staff concerns (e.g., cost, judgment) may improve evidence-based staff recommendations to patients seeking medical cannabis.

Cannabis use is associated with pain severity and interference among cancer survivors.

Context: Cannabis use for symptom management among individuals with cancer is increasingly common. Objectives: We sought to describe the 1) prevalence and characteristics of cannabis use, 2) perceived therapeutic benefits of cannabis use, and 3) examine how use of cannabis was associated with self-reported pain, mood, and general health outcomes among a representative sample of patients treated at NCI designated OHSU Knight Cancer Institute. Methods: We conducted a population-based, cross-sectional survey developed in conjunction with 11 other NCI designated cancer centers and distributed to eligible individuals. The survey inquired about characteristics of cannabis use, perception of therapeutic benefits, pain, mood, and general health. Responses were population weighted. We examined the association of cannabis use with self-reported pain, mood, and general health using logistic regression controlling for relevant sociodemographic and clinical characteristics. Results: 523 individuals were included in our analytic sample. 54% endorsed using cannabis at any time since their cancer diagnosis and 42% endorsed using cannabis during active treatment. The most endorsed reasons for use included: sleep disturbance (54.7%), pain (47.1%), and mood (42.6%). We found moderate pain was associated with more than a 2-fold (OR = 2.4 [95% CI = 1.3-4.6], p = 0.002) greater likelihood of self-reported cannabis use. Depressed mood or general health were not associated with cannabis use. Conclusions: In a state with medical and recreational cannabis legislation, a high number of cancer survivors report cannabis use. Those with pain were more likely to use cannabis. Oncologists should be aware of this trend and assess use of cannabis when managing long-term symptoms of cancer and its treatments.

Cannabis dispensary staff approaches to counseling on potential contraindications to cannabis use: insights from a national self-report survey.

BACKGROUND: Legal cannabis is available in more than half of the United States. Health care professionals (HCPs) rarely give recommendations on dosing or safety of cannabis due to limits imposed by policy and lack of knowledge. Customer-facing cannabis dispensary staff, including clinicians (pharmacists, nurses, physician's assistants), communicate these recommendations in the absence of HCP recommendations. Little is known about how dispensary staff approach individuals with complex medical and psychiatric comorbidities. Using responses from a national survey, we describe how cannabis dispensary staff counsel customers with medical and psychiatric comorbidities on cannabis use and examine whether state-specific cannabis policy is associated with advice given to customers. METHODS: National, cross-sectional online survey study from February 13, 2020 to October 2, 2020 of dispensary staff at dispensaries that sell delta-9-tetrahydrocannabinol containing products. Measures include responses to survey questions about how they approach customers with medical and psychiatric comorbidities; state medicalization score (scale 0-100; higher score indicates more similarity to regulation of traditional pharmacies); legalized adult-use cannabis (yes/no). We conducted multiple mixed effects multivariable logistic regression analyses to understand relationships between state medicalization and dispensary employees' perspectives. RESULTS: Of 434 eligible respondents, most were budtenders (40%) or managers (32%), and a minority were clinicians (18%). State medicalization score was not associated with responses to most survey questions. It was associated with increased odds of encouraging customers with medical comorbidities to inform their traditional HCP of cannabis use (Odds ratio [OR]=1.2, 95% confidence interval [CI] 1.0-1.4, p=0.03) and reduced odds of recommending cannabis for individuals with cannabis use disorder (CUD) (OR=0.8, 95% CI 0.7-1.0, p=0.04). Working in a state with legalized adult-use cannabis was associated with recommending traditional health care instead of cannabis in those with serious mental illness (OR 2.2, 95% CI 1.1-4.7, p=0.04). Less than half of respondents believed they had encountered CUD (49%), and over a quarter did not believe cannabis is addictive (26%). CONCLUSIONS: When managing cannabis dosing and safety in customers with medical and psychiatric comorbidity, dispensary staff preferred involving individuals' traditional HCPs. Dispensary staff were skeptical of cannabis being addictive. While state regulations of dispensaries may impact the products individuals have access to, they were not associated with recommendations that dispensary staff gave to customers. Alternative explanations for dispensary recommendations may include regional or store-level variation not captured in this analysis.

Prevalence and correlates of high-dose opioid use among survivors of head and neck cancer.

BACKGROUND: We characterized prescription opioid medication use up to 2 years following the head and neck cancer (HNC) diagnosis and examined associations with moderate or high daily opioid prescription dose. METHODS: Using administrative data from Veterans Health Administration, we conducted a retrospective cohort analysis of 5522 Veterans treated for cancers of the upper aerodigestive tract between 2012 and 2019. Data included cancer diagnosis and treatments, pain severity, prescription opioid characteristics, demographics, and other clinical factors. RESULTS: Two years post-HNC, 7.8% (n = 428) were receiving moderate or high-dose opioid therapy. Patients with at least moderate pain (18%, n = 996) had 2.48 times higher odds (95% CI = 1.94-3.09, p < 0.001) to be prescribed a moderate opioid dose or higher at 2 years post diagnosis. CONCLUSIONS: Survivors of HNC with at least moderate pain were at elevated risk of continued use of moderate and high dose opioids.

"You're Socially Distant and Trying Not to Be Emotionally Distant." Physicians' Perspectives of Communication and Therapeutic Relationships in the ICU During the COVID-19 Pandemic: A Qualitative Study.

To: 1) characterize how COVID-19-related policies influence patient-clinician communication and relationships in the ICU, with attention to race and ethnicity as factors and 2) identify interventions that may facilitate patient-clinician communication. DESIGN: We conducted a qualitative study between September 2020 and February 2021 that explored facilitators and barriers to patient-clinician communication and the formation of therapeutic relationships. We used thematic analysis to develop findings describing patient-communication and therapeutic relationships within the ICU early in the COVID-19 pandemic. SETTING: We purposively selected hospital dyads from regions in the United States that experienced early and/or large surges of patients hospitalized with COVID-19. SUBJECTS: We recruited a national sample of ICU physicians from Veteran Affairs (VA) Health Care Systems and their associated academic affiliate hospitals. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Twenty-four intensivists from seven VA hospitals and six academic-affiliate hospitals participated. Intensivists noted the disproportionate impact of the pandemic on among people holding minoritized racial and ethnic identities, describing how language barriers and restrictive visitation policies exacerbated institutional mistrust and compromised physicians' ability to develop therapeutic relationships. We also identified several perceived influences on patient-clinician communication and the establishment of therapeutic relationships. Barriers included physicians' fear of becoming infected with COVID-19 and use of personal protective equipment, which created obstacles to effective physical and verbal interactions. Facilitators included the presence of on-site interpreters, use of web-based technology to interact with family members outside the ICU, and designation of a care team member or specialist service to provide routine updates to families. CONCLUSIONS: The COVID-19 pandemic has threatened patient-clinician communication and the development of therapeutic relationships in the ICU, particularly among people holding minoritized racial and ethnic identities and their families. We identified several facilitators to improve patient-clinician communication as perceived by intensivists that may help improve trust and foster therapeutic alliances.

Women of the Gulf War: Understanding Their Military and Health Experiences Over 30 Years.

INTRODUCTION: Women Veterans of the Persian Gulf War (GW) expanded the military roles they had filled in previous military eras, with some women engaging in direct combat for the first time. Many GW service members, including women, had unique combat exposures to hazardous agents during deployment, which might have contributed to the development of chronic health problems. This study aims to understand the experiences of women GW Veterans (GWVs) as it is related to their military service and subsequent health in order to better inform and improve their clinical care. MATERIALS AND METHODS: We conducted in-depth interviews with 10 women GWVs to understand their experiences and perspectives about how their military service in the Gulf has impacted their lives and health. We used an integrated approach of content analysis and inductive thematic analysis to interpret interview data. RESULTS: Besides having many of the same war-related exposures as men, women faced additional challenges in a military that was inadequately prepared to accommodate them, and they felt disadvantaged as women within the military and local culture. After service, participants had emergent physical and mental health concerns, which they described as developing into chronic and complex conditions, affecting their relationships and careers. While seeking care and service connection at Veterans Health Administration (VA), women voiced frustration over claim denials and feeling dismissed. They provided suggestions of how VA services could be improved for women and GWVs. Participants found some nonpharmacological approaches for symptom management and coping strategies to be helpful. CONCLUSIONS: Women in the GW encountered challenges in military and healthcare systems that were inadequately prepared to address their needs. Women faced chronic health conditions common to GWV and voiced the desire to be understood as a cohort with unique needs. There is an ongoing need to expand services within the VA for women GWVs, particularly involving psychosocial support and management of chronic illness. While the small sample size can limit generalizability, the nature of these in-depth, minimally guided interviews provides a rich narrative of the women GWVs in this geographically diverse sample.

Complexity and Challenges of the Clinical Diagnosis and Management of Long COVID.

Importance: There is increasing recognition of the long-term health effects of SARS-CoV-2 infection (sometimes called long COVID). However, little is yet known about the clinical diagnosis and management of long COVID within health systems. Objective: To describe dominant themes pertaining to the clinical diagnosis and management of long COVID in the electronic health records (EHRs) of patients with a diagnostic code for this condition (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision [ICD-10] code U09.9). Design, Setting, and Participants: This qualitative analysis used data from EHRs of a national random sample of 200 patients receiving care in the Department of Veterans Affairs (VA) with documentation of a positive result on a polymerase chain reaction (PCR) test for SARS-CoV-2 between February 27, 2020, and December 31, 2021, and an ICD-10 diagnostic code for long COVID between October 1, 2021, when the code was implemented, and March 1, 2022. Data were analyzed from February 5 to May 31, 2022. Main Outcomes and Measures: A text word search and qualitative analysis of patients' VA-wide EHRs was performed to identify dominant themes pertaining to the clinical diagnosis and management of long COVID. Results: In this qualitative analysis of documentation in the VA-wide EHR, the mean (SD) age of the 200 sampled patients at the time of their first positive PCR test result for SARS-CoV-2 in VA records was 60 (14.5) years. The sample included 173 (86.5%) men; 45 individuals (22.5%) were identified as Black and 136 individuals (68.0%) were identified as White. In qualitative analysis of documentation pertaining to long COVID in patients' EHRs 2 dominant themes were identified: (1) clinical uncertainty, in that it was often unclear whether particular symptoms could be attributed to long COVID, given the medical complexity and functional limitations of many patients and absence of specific markers for this condition, which could lead to ongoing monitoring, diagnostic testing, and specialist referral; and (2) care fragmentation, describing how post-COVID-19 care processes were often siloed from and poorly coordinated with other aspects of care and could be burdensome to patients. Conclusions and Relevance: This qualitative study of documentation in the VA EHR highlights the complexity of diagnosing long COVID in clinical settings and the challenges of caring for patients who have or are suspected of having this condition.

Patient-clinician communication and patient-centered outcomes among patients with suspected stage I non-small cell lung cancer: a prospective cohort study.

Among patients with suspected early-stage non-small cell lung cancer (NSCLC), we sought to evaluate the association of patient-clinician communication (PCC) with patient-centered outcomes (PCOs). We conducted a multicenter, prospective cohort study examining PCOs at five time points, up to 12-months post-treatment. We used generalized estimating equation (GEE) models adjusted for sociodemographic and clinical variables to examine the relationship between PCC (dichotomized as high- or low-quality) and decisional conflict, treatment self-efficacy, and anxiety. The cohort included 165 patients who were 62% male with a mean age of 70.7 ± SD 8.1 years. Adjusted GEE analysis including 810 observations revealed high-quality PCC was associated with no decisional conflict (adjusted odds ratio [aOR] = 0.14, 95% CI = 0.07 to 0.27) and higher self-efficacy (ß = -0.26, 95% CI = -0.37 to -0.14). High-quality PCC was not associated with moderately severe anxiety (aOR = 0.68, 95% CI = 0.41 to 1.09), though was associated with decreased anxiety scores (ß = -3.91, 95% CI = -6.48 to -1.35). Among individuals with suspected early-stage NSCLC, high-quality PCC is associated with less decisional conflict and higher self-efficacy; the relationship with anxiety is unclear. Clinicians should prioritize enhanced treatment-related communication at critical and vulnerable periods in the cancer care trajectory to improve PCOs.

Health Experiences Research as a Resource and Mechanism for Veteran Engagement in VA Healthcare Research and Care Delivery.

Engaging patients in the research process helps to ensure researchers ask meaningful questions and generate useful evidence to inform healthcare decisions. In 2015, the Veterans Health Administration (VA) Health Services Research & Development (HSR&D) service convened a Veteran engagement workgroup, comprised of researchers, clinicians, and Veterans, to identify ways to integrate Veteran engagement into HSR&D. A subgroup was designated to explore the utility of health experiences research (research focused on enhancing understanding of people's experiences with healthcare and illnesses) as a mechanism to complement and broaden traditional engagement mechanisms. The subgroup recommended the VA adopt the Database of Individual Patient Experiences (DIPEx) methodology for conducting and disseminating health experiences research (HER). In this paper, we describe (1) the key components of the DIPEx approach, (2) how these components complement and broaden current methods of Veteran engagement, (3) an update on VA activities using the DIPEx approach, and (4) a roadmap for future VA HER activities.

Risk of Suicidal Self-directed Violence Among US Veteran Survivors of Head and Neck Cancer.

Importance: Head and neck cancer (HNC) survivors are about twice as likely to die by suicide compared with other cancer survivors. Objective: To examine the associations between precancer mental health and pain and postcancer receipt of mental health, substance use disorder (SUD), or palliative care services with risk of suicidal self-directed violence (SSDV). Design, Setting, and Participants: This retrospective cohort study used the Veterans Health Administration data of 7803 veterans with a diagnosis of HNC (stage I-IVB) who received cancer treatment between January 1, 2012, and January 1, 2018. Data were analyzed between May 2020 and July 2021. Exposures: Presence of precancer chronic pain and SUD diagnoses, and postcancer SUD, mental health, or palliative care treatment. Exposures were defined using International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes in Veterans Health Administration administrative data. Main Outcomes and Measures: Documented SSDV event, including suicide attempt or death by suicide, after HNC diagnosis. Results: Among the cohort of 7803 veterans (7685 [98.4%] male; mean [SD] age, 65 [10.7] years), 72 (0.9%) had at least 1 documented SSDV event following their cancer diagnosis, and 51 (0.7%) died by suicide. Four adjusted modified Poisson regression analyses identified that precancer chronic pain (incidence rate ratio [IRR], 2.58; 95% CI 1.54-4.32) or mood disorder diagnoses (IRR, 1.95; 95% CI, 1.17-3.24) were associated with higher risk of postcancer SSDV. Those who had at least 1 documented mental health (IRR, 2.73; 95% CI, 1.24-6.03) or SUD (IRR, 3.92; 95% CI, 2.46-6.24) treatment encounter in the 90 days following HNC diagnosis were at higher risk for SSDV. A palliative care encounter within 90 days of postcancer diagnosis was associated with decreased risk of SSVD (IRR, 0.49; 95% CI, 0.31-0.78). Conclusions and Relevance: In this cohort study, a high proportion of HNC survivors with an SSVD event died from their injuries. Identification of risk factors for SSDV among HNC survivors may help direct additional resources to those who are at high risk. Referral to palliative care appears to be an important component of supportive oncologic care to reduce the risk of SSDV.

Analysis of State Cannabis Laws and Dispensary Staff Recommendations to Adults Purchasing Medical Cannabis.

Importance: Over the last decade, cannabis has become more accessible through the proliferation of dispensaries in states that have legalized its use. Most patients using cannabis for medical purposes report getting advice from dispensaries, yet there has been little exploration of frontline dispensary staff practices. Objective: To describe the practices of frontline dispensary workers who interact with customers purchasing cannabis for medical purposes and assess whether dispensary practices are associated with medicalization of state cannabis laws (degree to which they resemble regulation of prescription or over-the-counter drugs) and statewide adult use. Design, Setting, and Participants: This nationwide cross-sectional survey study was conducted from February 13, 2020, to October 2, 2020, using an online survey tool. Potential respondents were eligible if they reported working in a dispensary that sells tetrahydrocannabinol-containing products and interacting with customers about cannabis purchases. Main Outcomes and Measures: Participant responses to questions about formulating customer recommendations and talking to customers about risks. Results: The 434 survey responses from 351 unique dispensaries were most often completed by individuals who identified as budtenders (40%), managers (32%), and pharmacists (13%). Most respondents reported basing customer recommendations on the customer's medical condition (74%), the experiences of other customers (70%), the customer's prior experience with cannabis (67%), and the respondent's personal experience (63%); fewer respondents relied on clinician input (40%), cost (45%), or inventory (12%). Most respondents routinely advised customers about safe storage and common adverse effects, but few counseled customers about cannabis use disorder, withdrawal, motor vehicle collision risk, or psychotic reactions. A higher state medicalization score was significantly associated with using employer training (odds ratio, 1.41; 95% CI, 1.18-1.67) and physician or clinician input (odds ratio, 1.23; 95% CI, 1.05-1.43) as a basis for recommendation. Medicalization score was not associated with counseling about cannabis risks. Conclusions and Relevance: This survey study provides insight into how frontline dispensary staff base cannabis recommendations and counsel about risks. The findings may have utility for clinicians to counsel patients who purchase cannabis, customers who want to be prepared for a dispensary visit, and policy makers whose decisions affect cannabis laws.

Associations of Pain Numeric Rating Scale Scores Collected during Usual Care with Research Administered Patient Reported Pain Outcomes.

OBJECTIVE: The purpose of this study is to examine the extent to which numeric rating scale (NRS) scores collected during usual care are associated with more robust and validated measures of pain, disability, mental health, and health-related quality of life (HRQOL). DESIGN: We conducted a secondary analysis of data from a prospective cohort study. SUBJECTS: We included 186 patients with musculoskeletal pain who were prescribed long-term opioid therapy. SETTING: VA Portland Health Care System outpatient clinic. METHODS: All patients had been screened with the 0-10 NRS during routine outpatient visits. They also completed research visits that assessed pain, mental health and HRQOL every 6 months for 2 years. Accounting for nonindependence of repeated measures data, we examined associations of NRS data obtained from the medical record with scores on standardized measures of pain and its related outcomes. RESULTS: NRS scores obtained in clinical practice were moderately associated with pain intensity scores (B's = 0.53-0.59) and modestly associated with pain disability scores (B's = 0.33-0.36) obtained by researchers. Associations between pain NRS scores and validated measures of depression, anxiety, and health related HRQOL were low (B's = 0.09-0.26, with the preponderance of B's < .20). CONCLUSIONS: Standardized assessments of pain during usual care are moderately associated with research-administered measures of pain intensity and would be improved from the inclusion of more robust measures of pain-related function, mental health, and HRQOL.

Biological measures and diagnostic tools for Gulf War Illness - A systematic review.

AIMS: Gulf War Illness (GWI) is a chronic multisymptom illness with debated etiology and pathophysiology. This systematic review catalogues studies of validated biological tests for diagnosing GWI and of associations between biological measures and GWI for their promise as biomarkers. MAIN METHODS: We searched multiple sources through February 2020 for studies of diagnostic tests of GWI and of associations between biological measures and GWI. We abstracted data on study design, demographics, and outcomes. We assessed the risk of bias of included studies. KEY FINDINGS: We did not identify any studies validating tests of biomarkers that distinguish cases of GWI from non-cases. We included the best-fitting studies, 32 completed and 24 ongoing or unpublished studies, of associations between GWI and biological measures. The less well-fitting studies (n = 77) were included in a Supplementary Table. Most studies were of the central nervous and immune systems and indicated a significant association of the biological measure with GWI case status. Biological measures were heterogeneous across studies. SIGNIFICANCE: Our review indicates that there are no existing validated biological tests to determine GWI case status. Many studies have assessed the potential association between a variety of biological measures and GWI, the majority of which pertain to the immune and central nervous systems. More importantly, while most studies indicated a significant association between biological measures and GWI case status, the biological measures across studies were extremely heterogeneous. Due to the heterogeneity, the focus of the review is to map out what has been examined, rather than synthesize information.

How medical are states' medical cannabis policies?: Proposing a standardized scale.

BACKGROUND: There are important differences in medical cannabis laws across the U.S.. However, prior studies investigating the effect of medical cannabis laws on outcomes disregard this heterogeneity. Findings from the body of literature using a simple dichotomous assessment of whether a particular state has enacted a medical cannabis law are equivocal or conflicting. To advance the science, a national advisory group of experts in medical cannabis developed and utilized a systematic methodology, the "medicalization of cannabis laws standardized scale" (MCLaSS), to characterize and quantify state laws' degree of medicalization, the extent to which medical cannabis is treated similarly to pharmaceutical medications. METHODS: We conducted a systematic review of state-level medical cannabis laws in the U.S. Using the novel MCLaSS, we calculated seven domain scores (patient-clinician relationship, manufacturing and testing, product labeling, types of products, supply and dose limit, prescription drug monitoring program, and dispensing practices) and a summary score for each state which had enacted medical cannabis laws as of July 2019. RESULTS: There is substantial heterogeneity in the degree of medicalization of states' medical cannabis laws, as demonstrated by the MCLaSS summary score, which ranged from 23 (least medicalized) to 86 (most medicalized). CONCLUSION: This methodology will advance the evidence base about the impact of medical cannabis laws on patient and public health outcomes, which is urgently needed to ensure the development of policies that minimize the risks and maximize the benefits of medical cannabis.

A qualitative study of VHA clinicians' knowledge and perspectives on cannabis for medical purposes.

BACKGROUND: The legalization of cannabis is expanding across the USA, and its use has increased significantly, including among Veterans. Although the Veterans Health Administration (VHA) abides by the classification of cannabis as a Schedule I substance, it recently recommended that clinicians discuss cannabis with their patients. Little is known about VHA clinicians' perspectives on and knowledge of cannabis. OBJECTIVE: We sought to better understand clinicians' attitudes, beliefs, knowledge and communication with patients regarding cannabis. METHODS: We conducted semi-structured phone interviews with 14 VHA clinicians. Interviews were audio-recorded, transcribed verbatim and analysed using qualitative thematic analysis. RESULTS: VA clinicians described ambivalence towards cannabis for therapeutic purposes and identified several factors that inhibit conversations about cannabis use with their patients including discomfort with the lack of product standardization; lack of research examining the effectiveness and risks of cannabis use; unfamiliarity with pharmacology, formulations, and dosing of cannabis; and uncertainty regarding VHA policy. Clinicians had differing views on cannabis in the context of the opioid crisis. CONCLUSIONS: VA clinicians face challenges in navigating the topic of medical cannabis. Educational materials about cannabis products, dose and harms would be helpful to clinicians.

Our research study examines Veterans Health Administration clinicians' attitudes, beliefs, knowledge and communication with patients about cannabis (marijuana) use. We conducted phone interviews with 14 VHA clinicians in order to describe their experiences of talking to their patients about cannabis. Interviews were audio-recorded, transcribed and analysed to identify themes. We describe both common and unique experiences. Our findings suggest that VA clinicians have feelings of uncertainty towards cannabis use for medical purposes and described several reasons that prevent conversations about cannabis use with their patients, including discomfort with the lack of product regulation; lack of research examining the effect cannabis has on the body; unfamiliarity with the different cannabis products that are available; and uncertainty about VHA policy. VA clinicians have diverse views of cannabis in relation to the opioid epidemic.

A Systematic Review of Therapeutic Interventions and Management Strategies for Gulf War Illness.

INTRODUCTION: After the 1990 to 1991 conflict in the Persian Gulf, many Gulf War Veterans began reporting numerous unexplained symptoms including, but not limited to, systemic pain, fatigue, flu-like symptoms, and difficulty with memory/concentration. These symptom clusters are now referred to as Gulf War Illness (GWI). Although the etiology of GWI is still debated, as many as 250,000 former service members have been continually suffering from GWI since 1991, making the need for treatment urgent. A broad variety of treatments have been considered for GWI, but there has not been a broad and comprehensive assessment of what is known and not known about GWI treatment. We conducted a systematic review to catalogue the types of treatments that have been examined for GWI, to evaluate the effectiveness and harms of these interventions, and to identify promising and ongoing areas of future GWI treatment research. MATERIALS AND METHODS: We searched electronic databases, trial registries, and reference lists through September 2019 for randomized controlled trial and nonrandomized controlled trial and cohort studies directly comparing interventions for Veterans with GWI to each other, placebo, or usual care. We abstracted data on study design, demographics, interventions, and outcomes. Two reviewers independently assessed studies for inclusion, quality, and strength of evidence (SOE) using prespecified criteria. We resolved discordant ratings by discussion and consensus. RESULTS: We identified 12 randomized controlled trials, each of which examined a different intervention for GWI. We found moderate SOE that cognitive behavioral therapy and exercise, separately and in combination, were associated with improvements in several GWI symptom domains. There was low SOE of benefit from two mindfulness-based interventions and continuous positive airway pressure (CPAP). Mindfulness-based stress reduction improved pain, cognitive functioning, fatigue, depression, and posttraumatic stress disorder (PTSD), whereas mind-body bridging improved fatigue, depression, posttraumatic stress disorder, and sleep, although pain and other outcomes did not improve. Continuous positive airway pressure improved overall physical health, pain, cognitive functioning, fatigue, mental health, and sleep quality in a small study of Veterans with sleep-disordered breathing and GWI. We found moderate SOE that doxycycline is ineffective for GWI in mycoplasma DNA-positive Veterans and increases the risk of adverse events compared with placebo. We also found 33 ongoing, single-arm pilot, or unpublished studies examining a variety of interventions. CONCLUSION: Cognitive behavioral therapy (moderate SOE), exercise (moderate SOE), and mindfulness-based interventions (low SOE) may be effective in improving several symptom domains in patients with GWI.
