Emergency Preparedness Drills for Active and Mass Shootings in Schools.

PURPOSE OF REVIEW: There is widespread use of emergency preparedness drills in public K-12 schools across the US, but considerable variability exists in the types of protocols used and how these practices are conducted. This review examines research into both "lockdown drills" and "active shooter drills" as it relates to their impact on participants across different outcomes and evaluations of their procedural integrity. RECENT FINDINGS: A number of studies on lockdown drills yielded largely consistent findings about their impacts, whereas findings related to the effects of active shooter drills are less uniform. The research also demonstrated that lockdown drills, though not active shooter drills, can help participants build skill mastery to be able to successfully deploy the procedure. Differences in how drills impact participants and whether they cultivate skill mastery are largely attributable to the type of drill being conducted. This review suggests that employing clearly defined drill procedures incorporating best practices, coupled with instructional training, can help schools prepare for emergencies without creating trauma for participants.

Experiences and Perceptions of Online Sexual Solicitation and Grooming of Minors: A Retrospective Report.

Internet predation of minors has become a focus of child sexual abuse research and legislation. Studies reveal that many American youth report experiencing sexual solicitation and sexual grooming online, but the youth perspective of these experiences has not been examined. This study examined retrospective perspectives of online sexual solicitation and grooming experienced as a minor. Participants were 1,133 undergraduate college students at two public institutions in the United States who completed an online survey retrospectively exploring Internet behaviors, experiences of online sexual solicitation or online grooming, and perceptions of the experience. Results showed that one-quarter of total participants conversed with adult strangers online as minors. Importantly, 65% of participants who chatted with adult strangers as minors experienced sexual solicitation from an adult stranger. Twenty-three percent of 1,133 total participants recalled having a long, intimate conversation as a minor with an adult stranger from an online chatroom that followed a pattern of online sexual grooming. While less than half (38%) of the youth who engaged in an intimate online relationship with an adult stranger met the adult in-person, a large majority of those who did meet in-person (68%) reported physical sexual intercourse. Implications for Internet safety and guidelines are discussed.

Both maternal and pup genotype influence ultrasonic vocalizations and early developmental milestones in tsc2 (+/-) mice.

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by tumor growth and neuropsychological symptoms such as autistic behavior, developmental delay, and epilepsy. While research has shed light on the biochemical and genetic etiology of TSC, the pathogenesis of the neurologic and behavioral manifestations remains poorly understood. TSC patients have a greatly increased risk of developmental delay and autism spectrum disorder, rendering the relationship between the two sets of symptoms an extremely pertinent issue for clinicians. We have expanded on previous observations of aberrant vocalizations in Tsc2 (+/-) mice by testing vocalization output and developmental milestones systematically during the early postnatal period. In this study, we have demonstrated that Tsc2 haploinsufficiency in either dams or their pups results in a pattern of developmental delay in sensorimotor milestones and ultrasonic vocalizations.

A novel, multiple symptom model of obsessive-compulsive-like behaviors in animals.

BACKGROUND: Current animal models of obsessive-compulsive disorder (OCD) typically involve acute, drug-induced symptom provocation or a genetic association with stereotypies or anxiety. None of these current models demonstrate multiple OCD-like behaviors. METHODS: Neonatal rats were treated with the tricyclic antidepressant clomipramine or vehicle between days 9 and 16 twice daily and behaviorally tested in adulthood. RESULTS: Clomipramine exposure in immature rats produced significant behavioral and biochemical changes that include enhanced anxiety (elevated plus maze and marble burying), behavioral inflexibility (perseveration in the spontaneous alternation task and impaired reversal learning), working memory impairment (e.g., win-shift paradigm), hoarding, and corticostriatal dysfunction. Dopamine D2 receptors were elevated in the striatum, whereas serotonin 2C, but not serotonin 1A, receptors were elevated in the orbital frontal cortex. CONCLUSIONS: This is the first demonstration of multiple symptoms consistent with an OCD-like profile in animals. Moreover, these behaviors are accompanied by biochemical changes in brain regions previously identified as relevant to OCD. This novel model of OCD demonstrates that drug exposure during a sensitive period can program disease-like systems permanently, which could have implications for current and future therapeutic strategies for this and other psychiatric disorders.
