Relations between higher- and lower-order alcohol and cannabis expectancies and simultaneous use frequency among undergraduate dual users

Simultaneous alcohol and cannabis (i.e. marijuana;[SAM]) use is prevalent among college students. There is limited research on expectancy effects for SAM use, which are known correlates of use frequency and mediators of treatment outcomes. We examined the unique associations of both positive and negative alcohol and cannabis expectancies with frequency of SAM use among college students. Participants were 1012 college students (70.9% female, 51.8% white, Mage = 19.63) from seven US universities who reported past-month alcohol and cannabis use (77.2% of the sample reported SAM use). Students completed measures of past-month typical weekly alcohol and cannabis frequency and quantity, alcohol and cannabis expectancies, and SAM frequency through an online self-reported survey. A negative binomial regression revealed that higher-order positive, but not negative, alcohol and cannabis expectancies were significant predictors of SAM frequency above and beyond frequency of alcohol and cannabis use, biological sex, and whether the survey was completed pre- or post-COVID-19 campus closures. Specifically, higher frequency SAM use was associated with weaker positive alcohol and stronger positive cannabis expectancies. A second negative binomial regression including lower-order expectancies found that SAM frequency was associated with weaker social and cognitive and behavioral impairment alcohol expectancies and stronger sexual and social facilitation cannabis and liquid courage alcohol expectancies, specifically. Results highlight the importance of comprehensively examining both higher- and lower-order alcohol and cannabis expectancies when examining SAM frequency, and provide avenues of targeted intervention to reduce SAM use among dual users.

Adapting practice in mental healthcare settings during the COVID-19 pandemic and other contagions: systematic review.

BACKGROUND: During the global COVID-19 pandemic, there has been guidance concerning adaptations that physical healthcare services can implement to aid containment, but there is relatively little guidance for how mental healthcare services should adapt service provision to better support staff and patients, and minimise contagion spread. AIMS: This systematic review explores service adaptations in mental health services during the COVID-19 pandemic and other contagions. METHOD: The Allied and Complementary Medicine database (AMED), the Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, Medline, PsycINFO and Web of Science were systematically searched for published studies from database inception to April 2020. Data were extracted focusing on changes to mental health services during contagion outbreaks. Data were analysed with thematic analysis. RESULTS: Nineteen papers were included: six correspondence/point-of-view papers, five research papers, five reflection papers, two healthcare guideline documents and one government document. Analysis highlighted four main areas for mental health services to consider during contagion outbreaks: infection control measures to minimise contagion spread, including procedural and practical solutions across different mental health settings; service delivery, including service changes, operational planning and continuity of care; staff well-being (psychological and practical support); and information and communication. CONCLUSIONS: Mental health services need to consider infection control measures and implement service changes to support continuity of care, and patient and staff well-being. Services also need to ensure they are communicating important information in a clear and accessible manner with their staff and patients, regarding service delivery, contagion symptoms, government guidelines and well-being.

Neuro-oncology practice guidelines from a high-volume surgeon at the COVID-19 epicenter.

BACKGROUND: During the coronavirus 19 (COVID-19) pandemic, physicians have begun adapting their daily practices to prevent transmissions. In this study we aimed to provide surgical neuro-oncologists with practice guidelines during the COVID-19 pandemic based on objective data from a high-volume brain tumor surgeon at the current COVID-19 epicenter. METHODS: All outpatient visits and surgeries performed by the senior author during the COVID-19 pandemic were compared between the initial quarantine (3/23/20-5/4/20), the plateau period following quarantine (5/5/20-6/27/20), and the second peak (6/28/20-7/20/20). In-person and telemedicine visits were evaluated for crossovers. Surgeries were subdivided based on lesion type and evaluated across the same time period. RESULTS: From 3/23/20-7/20/20, 469 clinic visits and 196 surgeries were identified. After quarantine was lifted, face-to-face visits increased (P < 0.01) yet no change in telehealth visits occurred. Of 327 telehealth visits, only 5.8% converted to in-person during the 4-month period with the most cited reason being patient preference (68.4%). Of the 196 surgeries performed during the pandemic, 29.1% occurred during quarantine, 49.0% during the plateau, and 21.9% occurred in the second peak. No COVID negative patients developed symptoms at follow-up. 55.6% were performed on malignant tumors and 31.6% were benign with no difference in case volumes throughout the pandemic. CONCLUSIONS: Despite exceptional challenges, we have maintained a high-volume surgical neuro-oncology practice at the epicenter of the COVID-19 pandemic. We provide the protocols implemented at our institution in order to maximize neuro-oncology care while mitigating risk of COVID-19 exposure to both patients and providers.

The Effects of Lockdown During the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Pandemic on Neurotrauma-Related Hospital Admissions.

BACKGROUND: The response to the global severe acute respiratory syndrome coronavirus 2 pandemic culminated in mandatory isolation throughout the world, with nationwide confinement orders issued to decrease viral spread. These drastic measures were successful in "flattening the curve" and maintaining the previous rate of coronavirus disease 2019 infections and deaths. To date, the effects of the coronavirus disease 2019 pandemic on neurotrauma has not been reported. METHODS: We retrospectively analyzed hospital admissions from Ryder Trauma Center at Jackson Memorial Hospital, during the months of March and April from 2016 to 2020. Specifically, we identified all patients who had cranial neurotrauma consisting of traumatic brain injury and/or skull fractures, as well as spinal neurotrauma consisting of vertebral fractures and/or spinal cord injury. We then performed chart review to determine mechanism of injury and if emergent surgical intervention was required. RESULTS: Compared with previous years, we saw a significant decline in the number of neurotraumas during the pandemic, with a 62% decline after the lockdown began. The number of emergent neurotrauma surgical cases also significantly decreased by 84% in the month of April. Interestingly, although the number of vehicular traumas decreased by 77%, there was a significant 100% increase in the number of gunshot wounds. CONCLUSIONS: Population seclusion had a direct effect on the frequency of neurotrauma, whereas the change in relative proportion of certain mechanisms may be associated with the psychosocial effects of social distancing and quarantine.
