Psilocybin-occasioned mystical-type experience in combination with meditation and other spiritual practices produces enduring positive changes in psychological functioning and in trait measures of prosocial attitudes and behaviors.

Psilocybin can occasion mystical-type experiences with participant-attributed increases in well-being. However, little research has examined enduring changes in traits. This study administered psilocybin to participants who undertook a program of meditation/spiritual practices. Healthy participants were randomized to three groups (25 each): (1) very low-dose (1 mg/70 kg on sessions 1 and 2) with moderate-level ("standard") support for spiritual-practice (LD-SS); (2) high-dose (20 and 30 mg/70 kg on sessions 1 and 2, respectively) with standard support (HD-SS); and (3) high-dose (20 and 30 mg/70kg on sessions 1 and 2, respectively) with high support for spiritual practice (HD-HS). Psilocybin was administered double-blind and instructions to participants/staff minimized expectancy confounds. Psilocybin was administered 1 and 2 months after spiritual-practice initiation. Outcomes at 6 months included rates of spiritual practice and persisting effects of psilocybin. Compared with low-dose, high-dose psilocybin produced greater acute and persisting effects. At 6 months, compared with LD-SS, both high-dose groups showed large significant positive changes on longitudinal measures of interpersonal closeness, gratitude, life meaning/purpose, forgiveness, death transcendence, daily spiritual experiences, religious faith and coping, and community observer ratings. Determinants of enduring effects were psilocybin-occasioned mystical-type experience and rates of meditation/spiritual practices. Psilocybin can occasion enduring trait-level increases in prosocial attitudes/behaviors and in healthy psychological functioning. Trial Registration ClinicalTrials.gov Identifier NCT00802282.

Patient access and 1-year outcomes of percutaneous coronary intervention facilities with and without on-site cardiothoracic surgery: insights from the Veterans Affairs (VA) Clinical Assessment, Reporting, and Tracking (CART) program.

BACKGROUND: The safety of percutaneous coronary intervention (PCI) at medical facilities without on-site cardiothoracic (CT) surgery has been established in clinical trials. However, the comparative effectiveness of this strategy in real-world practice, including impact on patient access and outcomes, is uncertain. The Veterans Affairs (VA) health care system has used this strategy, with strict quality oversight, since 2005, and can provide insight into this question. METHODS AND RESULTS: Among 24,387 patients receiving PCI at VA facilities between October 2007 and September 2010, 6616 (27.1%) patients underwent PCI at facilities (n=18) without on-site CT surgery. Patient drive time (as a proxy for access), procedural complications, 1-year mortality, myocardial infarction, and rates of subsequent revascularization procedures were compared by facility. Results were stratified by procedural indication (ST-segment-elevation myocardial infarction versus non-ST-segment-elevation myocardial infarction/unstable angina versus elective) and PCI volume. With the inclusion of PCI facilities without on-site CT surgery, median drive time for patients treated at those facilities decreased by 90.8 minutes (P<0.001). Procedural need for emergent coronary artery bypass graft and mortality rates were low and similar between facilities. Adjusted 1-year mortality and myocardial infarction rates were similar between facilities (hazard ratio in PCI facilities without relative to those with on-site CT surgery, 1.02; 95% confidence interval, 0.87-1.2), and not modified by either PCI indication or PCI volume. Subsequent revascularization rates were higher at sites without on-site CT surgery facilities (hazard ratio, 1.21; 95% confidence interval, 1.03-1.42). CONCLUSIONS: This study suggests that providing PCI facilities without on-site CT surgery in an integrated health care system with quality oversight improves patient access without compromising procedural or 1-year outcomes.

Psilocybin occasioned mystical-type experiences: immediate and persisting dose-related effects.

RATIONALE: This dose-effect study extends previous observations showing that psilocybin can occasion mystical-type experiences having persisting positive effects on attitudes, mood, and behavior. OBJECTIVES: This double-blind study evaluated psilocybin (0, 5, 10, 20, 30 mg/70 kg, p.o.) administered under supportive conditions. METHODS: Participants were 18 adults (17 hallucinogen-naïve). Five 8-h sessions were conducted individually for each participant at 1-month intervals. Participants were randomized to receive the four active doses in either ascending or descending order (nine participants each). Placebo was scheduled quasi-randomly. During sessions, volunteers used eyeshades and were instructed to direct their attention inward. Volunteers completed questionnaires assessing effects immediately after and 1 month after each session, and at 14 months follow-up. RESULTS: Psilocybin produced acute perceptual and subjective effects including, at 20 and/or 30 mg/70 kg, extreme anxiety/fear (39% of volunteers) and/or mystical-type experience (72% of volunteers). One month after sessions at the two highest doses, volunteers rated the psilocybin experience as having substantial personal and spiritual significance, and attributed to the experience sustained positive changes in attitudes, mood, and behavior, with the ascending dose sequence showing greater positive effects. At 14 months, ratings were undiminished and were consistent with changes rated by community observers. Both the acute and persisting effects of psilocybin were generally a monotonically increasing function of dose, with the lowest dose showing significant effects. CONCLUSIONS: Under supportive conditions, 20 and 30 mg/70 kg psilocybin occasioned mystical-type experiences having persisting positive effects on attitudes, mood, and behavior. Implications for therapeutic trials are discussed.

Short course of omeprazole: a better first diagnostic approach to noncardiac chest pain than endoscopy, manometry, or 24-hour esophageal pH monitoring.

UNLABELLED: Noncardiac chest pain (NCCP) presents as a frequent diagnostic challenge, with patients tending to use a disproportionate level of health care resources. Gastroesophageal reflux disease (GERD) is the most frequent cause of NCCP. GOALS: To test the efficacy of a potent acid-suppressing agent as a diagnostic test in the evaluation of NCCP and to compare it with three commonly used tests. STUDY: Eighteen men and 24 women, aged 22 to 77 years, who presented with recurrent chest pain complaints of a noncardiac etiology, as determined by rest/stress perfusion imaging with technetium Tc99m sestamibi (MIBI), were enrolled in a prospective, double-blinded, placebo-controlled, crossover trial using high-dose omeprazole. Thirty-seven patients completed both arms of the trial. Findings were compared with those of endoscopy, manometry, and ambulatory 24-hour two-channel esophageal pH monitoring. All patients underwent initial diagnostic upper endoscopy, esophageal manometry, and 24-hour pH monitoring. Patients were then randomly assigned to either placebo or omeprazole (40 mg/d orally twice daily) for 14 days, washed out for 21 days, and then crossed over. Patient's symptoms were determined using a Visual Analogue Scale to measure the severity of chest pain before and after each period. RESULTS: Seventy-one percent of patients in the omeprazole arm reported improved chest pain, whereas only 18% in the placebo arm did. Abnormal results on manometry (20%), 24-hour pH monitoring (42%), or endoscopy with visual evidence of esophagitis (26%) were found less frequently. Combination of the three tests did not significantly increase their usefulness. In NCCP patients with GERD, as defined by positive results on a 24-hour pH test or presence of esophagitis on endoscopy, omeprazole treatment led to a response in 95% of patients, whereas 90% of GERD-positive patients treated with placebo did not respond. Of NCCP patients determined to be GERD negative, 39% responded to omeprazole. CONCLUSIONS: Omeprazole as a first diagnostic tool in the evaluation of MIBI-negative NCCP is sensitive and specific for determining the cause of NCCP. Endoscopy, manometry, and 24-hour pH monitoring were not only less sensitive in diagnosing NCCP, but they were significantly more expensive.
