The separate and joint effects of recent interpersonal abuse and cannabis use on psychotic experiences: findings from students in higher education in the United States.

BACKGROUND: Various forms of interpersonal abuse (e.g., physical, emotional, sexual) and cannabis use across the lifespan have both been known to increase odds of psychotic experiences; however, there have been few studies examining their separate and joint effects in the United States. METHODS: We analyzed data from the Healthy Minds Study (2020-2021) and used multivariable logistic regression and interaction contrast ratios to assess separate and joint effects of interpersonal abuse (past 12 months) and cannabis use (past 30 days) on psychotic experiences (past 12 months). RESULTS: Students who only used cannabis had significantly greater odds of psychotic experiences (aOR: 1.70; 95% CI 1.58-1.82), as well as those who only experienced interpersonal abuse (aOR: 2.40; 95% CI 2.25-2.56). However, those who reported both cannabis use and interpersonal abuse had the greatest odds, exceeding the sum of these individual effects (the combined effect aOR: 3.46; 95% CI 3.19-3.76). CONCLUSIONS: Recent interpersonal abuse and recent cannabis use both separately and jointly increase odds of having recent psychotic experiences. Future research should continue to examine the potential interactive and additive impact of multiple known exposures to better inform primary and secondary prevention efforts.

Food Insecurity and Substance Use Among Young Adult College Students in the United States.

BACKGROUND: Food insecurity is prevalent among college students in the United States and has been associated with substance use. We sought to provide updated prevalence estimates and associations between food insecurity and a broad range of substances during the SARS-CoV-2 pandemic. METHODS: Using cross-sectional data from the Health Minds Study (N = 94,722; September 2020-June 2021), we used multivariable logistic regression to examine associations between food insecurity and several substances, adjusting for age, gender, race/ethnicity, hours worked, and residence. We then added a block of adjustments consisting of mental health factors (depression, anxiety, loneliness, financial stress). RESULTS: Food insecurity was associated with significantly greater odds of having used most individual substances, including greater odds of binge drinking (adjusted odds ratio [aOR], 1.21; 95% confidence interval [CI], 1.13-1.30), cigarette use (aOR, 1.91; 95% CI, 1.73-2.10), vaping (aOR, 1.74; 95% CI, 1.62-1.87), and a range of illicit or prescription drugs (using any illicit/prescription drug; aOR, 1.43; 95% CI, 1.32-1.55) These associations attenuated and many lost significance after adjusting for mental health factors. CONCLUSIONS: This study found evidence to suggest that food insecurity is related to substance use in a large sample of young adult college students in the United States, calling for targeted interventions.

Mental health differences between multiracial and monoracial college students in the United States: Emerging racial disparities.

BACKGROUND: Multiracial individuals appear to be at higher risk for mental health problems; however, more research is needed to confirm these racial disparities among young adult college populations. METHODS: We analyzed data from the Health Minds Study (N = 99728 young adult college students aged 18-34), collected online across 140 college campuses from September 2020 to June 2021. We used multivariable logistic regression to examine associations between multiracial identity and several mental health outcomes, including mental and behavioral health (depression, anxiety, languishing, perceived need, loneliness), self-injurious behaviors (non-suicidal self-injury, suicidal ideation, suicide plan, suicide attempt), and history of lifetime psychiatric disorders, adjusting for age and gender. RESULTS: Almost a tenth of the weighted sample were multiracial. Multiracial students had greater odds of all mental and behavioral health outcomes, self-injurious behaviors (though only marginally significant for suicide attempt), and most lifetime psychiatric disorders. CONCLUSION: Multiracial young adult college students were more likely to have mental health problems than their monoracial counterparts, calling for targeted preventive interventions on college campuses to address these mental health disparities.

Catalytic pyrolysis of lignocellulosic biomass for bio-oil production: A review.

Catalytic pyrolysis has been widely explored for bio-oil production from lignocellulosic biomass owing to its high feasibility and large-scale production potential. The aim of this review was to summarize recent findings on bio-oil production through catalytic pyrolysis using lignocellulosic biomass as feedstock. Lignocellulosic biomass, structural components and fundamentals of biomass catalytic pyrolysis were explored and summarized. The current status of bio-oil yield and quality from catalytic fast pyrolysis was reviewed and presented in the current review. The potential effects of pyrolysis process parameters, including catalysts, pyrolysis conditions, reactor types and reaction modes on bio-oil production are also presented. Techno-economic analysis of full-scale commercialization of bio-oil production through the catalytic pyrolysis pathway was reviewed. Further, limitations associated with current practices and future prospects of catalytic pyrolysis for production of high-quality bio-oils were summarized. This review summarizes the process of bio-oil production from catalytic pyrolysis and provides a general scientific reference for further studies.

Food insecurity and mental health among young adult college students in the United States.

BACKGROUND: Food insecurity is prevalent among college students in the United States and has been associated with mental health problems. However, the literature is not entirely consistent and is missing key aspects of mental health. METHODS: Using cross-sectional data from the Health Minds Study (N = 96,379; September 2020-June 2021), we used multivariable logistic regression to examine associations between food insecurity and several aspects of mental health (i.e., depression, anxiety, languishing, perceived need, loneliness, self-injurious behaviors), adjusting for age, gender, race/ethnicity, financial distress, and parental education. RESULTS: Food insecurity was associated with greater odds of having depression, anxiety, languishing, perceived need for help, loneliness, and self-injurious behaviors, adjusting for sociodemographic characteristics and markers of socioeconomic status. CONCLUSION: This study found evidence to suggest that food insecurity is related to poor mental health in a large sample of young adult college students in the United States, calling for targeted interventions.

Clinical observation of 60 cases of treating cognitive disorder after cerebral injury in combination with scalp acupuncture and cognitive training.

To observe the clinical effect of scalp acupuncture combined with cognitive training on cognitive disorder after cerebral injury.Around 60 cases of cerebral injury patients for hospitalization in rehabilitation department of Chongqing Three Gorges Central Hospital from July in 2015 to June in 2017 are divided into control group and treatment group of 30 cases for each at random. The control group received routine treatment and cognitive rehabilitation training for 12 weeks. The treatment group received conventional treatment, cognitive rehabilitation training, and scalp acupuncture. Acupuncture with a scalp acupuncture is provided for the treatment group besides adopting above conventional treatment and rehabilitation training method.Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) score of both groups increases obviously after treatment compared with that before treatment, and there is difference (P < .01) through contrast. And LOTCA score of treatment group is higher than that of control group (P < .05) after treatment.Scalp acupuncture in combination with cognitive training can effectively improve cognitive disorder degree of patients with cerebral injury, and the effect is more significant compared with simple cognitive rehabilitation training, thus it is worth of research and application.

Generalized shift-rotation absolute measurement method for high-numerical-aperture spherical surfaces with global optimized wavefront reconstruction algorithm.

In this paper, a generalized shift-rotation absolute measurement method is proposed to measure the absolute surface shape of high-numerical-aperture spherical surfaces. Based on the wavefront difference method, the high order misalignment aberrations can be removed from the measurements. Our generalized shift-rotation absolute measurement process only needs one rotational measurement position and one translational measurement position. A wavefront reconstruction method based on the self-adaptive differential evolution algorithm is proposed to calculate the Zernike polynomials coefficient ai of the absolute surface shape Wtest(x,y), the rotation angle Δθ, the translation δx along the x axis, and the translation δy along the y axis. The translation error and rotation error in other absolute measurement methods are avoided using our generalized shift-rotation absolute measurement method. Experimental absolute results of the test surface and reference surface are given and the difference of reference surface shapes between two testings in experiments is 0.12 nm root mean square.
