Systematic combinations of major cannabinoid and terpene contents in Cannabis flower and patient outcomes: a proof-of-concept assessment of the Vigil Index of Cannabis Chemovars.

Background: Little is known about the frequency with which different combinations of phytochemicals (chemovars) arise in Cannabis flower or whether common chemovars are associated with distinct pharmacodynamics and patient health outcomes. This study created a clinically relevant, user-friendly, scalable chemovar indexing system summarizing primary cannabinoid and terpene contents and tested whether the most frequently consumed chemovars differ in their treatment effectiveness and experienced side effects.

Methods: Between 09/10/2016 and 03/11/2021, 204 people used the freely available, educational mobile software application, Releaf App, to record 6309 real-time consumption sessions using 633 distinct Cannabis flower products, unique at the user level, with terpene and cannabinoid potency information.

The impact of Covid-19 on older workers' employment and Social Security spillovers.

Unlabelled: The COVID-19 pandemic represents a major threat to health and economic well-being in the USA, especially for older and disabled workers, and may spill over onto Social Security. We use individual-level from the Current Population Survey, state-level monthly Social Security administrative data on disability benefit applications, and national-level monthly data on Social Security retirement benefit applications to assess the impact of the pandemic on older adults' employment and benefit claiming. State-level monthly Google Trends data are used as a leading indicator of future claiming in the population.

The Effects of Consuming Flower for Treatment of Fatigue.

Objectives: We measure for the first time how commercially available flower products affect feelings of fatigue.

Methods: A total of 1,224 people recorded 3,922 flower self-administration sessions between June 6, 2016, and August 7, 2019, using the Releaf App. Usage sessions included real-time subjective changes in fatigue intensity levels prior to and following consumption, flower characteristics (labeled phenotype, cannabinoid potency levels), combustion method, and any potential experienced side effects.

Cannabis consumption and prosociality.

The existing literature largely focuses on health risks and other pharmacodynamics of using cannabis, with fewer investigations of other normative psychological effects from consumption among otherwise healthy people. We measured several basic constructs of social psychology corresponding to the concept of prosociality among 146 healthy young adults between 18 and 25 years (M = 18.9, SD = 1.

The Effectiveness of Common Cannabis Products for Treatment of Nausea.

Goals: We measure for the first time how a wide range of cannabis products affect nausea intensity in actual time.

Background: Even though the Cannabis plant has been used to treat nausea for millennia, few studies have measured real-time effects of common and commercially available cannabis-based products.

Study: Using the Releaf App, 886 people completed 2220 cannabis self-administration sessions intended to treat nausea between June 6, 2016 and July 8, 2019.

The effectiveness of inhaled Cannabis flower for the treatment of agitation/irritability, anxiety, and common stress.

Background: An observational research design was used to evaluate which types of commonly labeled Cannabis flower product characteristics are associated with changes in momentary feelings of distress-related symptoms.

Methods: We used data from 2306 patient-directed cannabis administration sessions among 670 people who used the real-time Cannabis effects recording software, Releaf App, between June 6, 2016, and February 23, 2019, for tracking the effects of Cannabis flower consumption. Fixed effects multivariable panel regression techniques were used to establish overall relief by symptom type and to determine which labeled product characteristics (e.

Does increasing access-to-care delay accessing of care? Evidence from kidney transplantation.

Policies increasing healthcare availability might decrease the cost of delaying accessing of care, leading to potential negative consequences if patients delay treatment. We analyze a policy designed to increase access to kidney transplantation through the use of time since dialysis inception to prioritize patients for transplant, which was piloted at 26 of the 271 kidney transplant centers in the United States in 2006 and 2007. We model the patient's optimization problem comparing the benefits and costs of early waitlisting and predict that the policy change will lead to delayed waitlisting.

Alleviative effects of Cannabis flower on migraine and headache.

Objective: Few studies to date have measured the real-time effects of consumption of common and commercially available Cannabis products for the treatment of headache and migraine under naturalistic conditions. This study examines, for the first time, the effectiveness of using dried Cannabis flower, the most widely used type of Cannabis product in the United States, in actual time for treatment of headache- and migraine-related pain and the associations between different product characteristics and changes in symptom intensity following Cannabis use.

Methods: Between 06/10/2016 and 02/12/2019, 699 people used the Releaf Application to record real-time details of their Cannabis use, including product characteristics and symptom intensity levels prior to and following self-administration; data included 1910 session-level attempts to treat headache- (1328 sessions) or migraine-related pain (582 sessions).

The Effectiveness of Flower for Immediate Relief from Symptoms of Depression.

: Scientific research on how consumption of whole, natural flower affects low mood and behavioral motivations more generally is largely nonexistent, and few studies to date have measured how common and commercially available flower used may affect the experience of "depression" in real-time. : We observed 1,819 people who completed 5,876 cannabis self-administration sessions using the ReleafApp™ between 06/07/2016 and 07/08/2019, with the goal of measuring real-time effects of consuming flower for treating symptoms of depression. Results: On average, 95.

Are Transplant Centers That Meet Insurer Minimum Volume Requirements Better Quality?

A pervasive viewpoint in health care is that higher patient volume leads to better outcomes, implying that facility volume can be used to identify high-quality providers. Hundreds of studies documenting a positive correlation between hospital volume and patient survival have motivated payers to use arbitrary minimum volume standards for elective surgical procedures, though it is unknown whether these policies actually improve patient outcomes. Using an instrumental variables approach, we show that minimum volume requirements in kidney transplantation do not reduce posttransplant mortality.

The Association between Cannabis Product Characteristics and Symptom Relief.

Federal barriers and logistical challenges have hindered measurement of the real time effects from the types of cannabis products used medically by millions of patients in vivo. Between 06/06/2016 and 03/05/2018, 3,341 people completed 19,910 self- administrated cannabis sessions using the mobile device software, ReleafApp to record: type of cannabis product (dried whole natural Cannabis flower, concentrate, edible, tincture, topical), combustion method (joint, pipe, vaporization), Cannabis subspecies (C. indica and C.

The Role of Cannabis within an Emerging Perspective on Schizophrenia.

Approximately 0.5% of the population is diagnosed with some form of schizophrenia, under the prevailing view that the pathology is best treated using pharmaceutical medications that act on monoamine receptors. We briefly review evidence on the impact of environmental forces, particularly the effect of autoimmune activity, in the expression of schizophrenic profiles and the role of therapy for regulating immunological functioning.

Effectiveness of Raw, Natural Medical Flower for Treating Insomnia under Naturalistic Conditions.

: We use a mobile software application (app) to measure for the first time, which fundamental characteristics of raw, natural medical flower are associated with changes in perceived insomnia under naturalistic conditions. : Four hundred and nine people with a specified condition of insomnia completed 1056 medical cannabis administration sessions using the Releaf App educational software during which they recorded real-time ratings of self-perceived insomnia severity levels prior to and following consumption, experienced side effects, and product characteristics, including combustion method, cannabis subtypes, and/or major cannabinoid contents of cannabis consumed. Within-user effects of different flower characteristics were modeled using a fixed effects panel regression approach with standard errors clustered at the user level.

Accuracy of Patient Opioid Use Reporting at the Time of Medical Cannabis License Renewal.

The decision to authorize a patient for continued enrollment in a state-sanctioned medical cannabis program is difficult in part due to the uncertainty in the accuracy of patient symptom reporting and health functioning including any possible effects on other medication use. We conducted a pragmatic convenience study comparing patient reporting of previous and current prescription opioid usage to the opioid prescription records in the Prescription Monitoring Program (PMP) among 131 chronic pain patients (mean age = 54; 54% male) seeking the first annual renewal of their New Mexico Medical Cannabis Program (NMMCP) license. Seventy-six percent of the patients reported using prescription opioids prior to enrollment in the NMMCP, however, the PMP records showed that only 49% of the patients were actually prescribed opioids in the six months prior to enrollment.

Organizational learning-by-doing in liver transplantation.

Organizational learning-by-doing implies that production outcomes improve with experience. Prior empirical research documents the existence of organizational learning-by-doing, but provides little insight into why some firms learn while others do not. Among the 124 U.

How nurse gender influences patient priority assignments in US emergency departments.

The goals of this study were to compare whether emergency department (ED) patients' pain intensity (PI) is measured differently by male and female nurses and to determine whether PI, heart rate (HR), and respiratory rate (RR) were used to prioritize patient urgency differently by male and female nurses. The associations between patients' PI|HR|RR and the Emergency Severity Index (ESI) scores they were assigned by attending nurses were analyzed using a national database of electronic medical records of US Veterans Affairs ED patients from 2008 to 2012. A total of 129,991 patients presenting for emergency care (Mage = 59.
