With the advent of human neuroimaging, researchers were drawn to the idea that by better understanding the human brain, more effective mental health interventions could be developed. It has been more than 20 years since the first functional magnetic resonance imaging (fMRI) studies were conducted to examine changes in brain activation with anxiety-related treatments and more than 60 studies have since been published in this vein. For the current review, we conduct a systematic review of this literature, focusing on adult studies using task-based fMRI to measure brain activation changes with pharmacologic or psychotherapy interventions for phobia, social anxiety disorder, panic disorder, generalized anxiety disorder, posttraumatic stress disorder, and obsessive-compulsive disorder.

The viral load of COVID-19 in untreated wastewater from Idaho's capital city Boise, ID (Ada County) has been used to predict changes in hospital admissions (statewide in Idaho) and deaths (Ada County) using distributed fixed lag modeling and artificial neural networks (ANN). The wastewater viral counts were used to determine the lag time between peaks in wastewater viral counts and COVID-19 hospitalizations as well as deaths (14 and 23 days, respectively). Quantitative measurement of SARS-CoV-2 viral RNA counts in the untreated wastewater was determined three times a week using RT-qPCR over a span of 13 months.

Healthcare is dynamic as demographics, diseases, and therapeutics constantly evolve. This dynamic nature induces inevitable distribution shifts in populations targeted by clinical AI models, often rendering them ineffective. Incremental learning provides an effective method of adapting deployed clinical models to accommodate these contemporary distribution shifts.

COVID-19 is a major, urgent, and ongoing threat to global health. Globally more than 24 million have been infected and the disease has claimed more than a million lives as of November 2020. Predicting which patients will need respiratory support is important to guiding individual patient treatment and also to ensuring sufficient resources are available.

Background: The link between facial affect recognition and criminal justice involvement has been extensively researched, yet there are virtually no data on the capacity for facial affect recognition in post-incar+cerated individuals, and the results of many studies are limited due to a narrow focus on psychopathy rather than offence category.

Aims: To test the first hypothesis that individuals reporting a history of a violent offence would show a deficit in facial affect recognition and the second hypothesis that the violent offender's deficit would be exclusive to recognition of negative expressions, not affecting positive or neutral expressions.

Method: Post-incarcerated individuals (N = 298) were recruited online through Qualtrics and completed questionnaires assessing their criminal justice background and demographics.

Most predictors of future criminal justice involvement are gender neutral. However, recent research has stressed the importance of physical and sexual abuse as a precursor of incarceration for women. The aim of the present study was to assess the influence of a history of physical and sexual abuse on mental health, substance use, and criminal justice history for men and women under community corrections supervision.

The results of two experiments supported the hypothesis that, for sexist men, exposure to sexist humor can promote the behavioral release of prejudice against women. Experiment 1 demonstrated that hostile sexism predicted the amount of money participants were willing to donate to a women's organization after reading sexist jokes but not after reading nonhumorous sexist statements or neutral jokes. Experiment 2 showed that hostile sexism predicted the amount of money participants cut from the budget of a women's organization relative to four other student organizations upon exposure to sexist comedy skits but not neutral comedy skits.
