The investigative team will conduct a 2-arm randomized control trial to examine the preliminary effect of LinkPositively+ (LPP) an enhanced version of LinkPositively (LP) mobile app on improved HIV care outcomes including improved retention in HIV care, ART adherence, and viral suppression using hair sample analysis and passive electronic, medical record review, and secondarily, self-reported increased social support via activation of social support networks (i.e., assessed by utilization), self-efficacy, and utilization of ancillary support services at baseline, 3- and 6-month post enrollment. Black women living with HIV (WLHA) with a lifetime history of interpersonal violence, who have been linked to care but may have fallen out of care in the past year will be randomized 1:1 to either the LP arm or the LPP arm.

This study is a 4-year randomized, controlled trial comparing cognitive behavioral therapy (CBT) to usual clinical care for children (aged 6-14 years) with autism and emotional dysregulation (e.g., irritability, anxiety). We will randomly assign 50 mental health clinicians, each treating 2 youth (N = 100 youth total), to CBT program for emotional dysregulation and core autism symptoms with weekly live consultation with an expert or to usual clinical care augmented by self-instruction in CBT, in a 1:1 allocation. The CBT manual is well-supported in our efficacy research, has been replicated in other centers, is free/open-access (meya.ucla.edu), and has user-friendly digital and traditional print materials for mental health clinicians (e.g., psychologists, counselors) to use in preparing for and conducting therapy sessions. The primary outcome measure will be assessed weekly. Additional assessments will occur at Screening, Mid-treatment, Post- treatment and 3-month Follow-up. Read Less

Pregnancy elicits adaptive changes in uteroplacental blood flow, which are altered at high altitude and may contribute to the observed 3-fold increase in intrauterine growth restriction (IUGR) and preeclampsia (PreE). The investigators propose to collect myometrial, cord blood, and placental tissue samples from women at high altitude (Summit County) and low altitude (Denver) in Colorado in order to determine if residence at altitude during pregnancy changes the vasoreactivity of myometrial arteries (MA). If altered MA vasoreactivity is found, further studies may be able to link these changes to the increased rates of PreE and IUGR at altitude and contribute to the understanding of these two disorders.

The overall objective of this study is to examine physical exercise as an intervention for ADHD. The rationale for the proposed study is that physical exercise could serve as an effective treatment for college students with ADHD that has low costs, low risks, and ancillary health benefits and may address the limitations of existing treatments. The central hypothesis is that college students with ADHD will exhibit greater degrees of improvement in executive functioning (i.e., sustained attention, working memory) immediately following sprint interval training (SIT), relative to non-ADHD peers. This hypothesis was formulated based on preliminary studies demonstrating reduced ADHD symptoms and improved executive functioning following physical exercise. Multiple 2 (ADHD vs. control) x 2 (male vs. female) x 2 (exercise vs. none) repeated measures ANOVAs will be conducted to compare students with ADHD (n = 24) to controls (n = 24). The expected outcomes are to confirm this hypothesis and demonstrate the need for further study of physical exercise. If confirmed, the results will provide pilot data for a larger NIH grant proposal aimed at further examining the acute effects of physical exercise (i.e., improved cognitive functioning immediately following exercise) and also the chronic effects of physical exercise (i.e., improved functioning after engaging in regular exercise for an extended period). This outcome is expected to have an important positive impact because physical exercise may serve as an effective treatment for college students with ADHD that is less risky than stimulants, less time-consuming than therapy, and provides ancillary health benefits (i.e., increasing physical fitness, decreasing obesity).

The investigators will examine the acute effects of stimulant medication on executive functioning. The rationale for the proposed study is to examine the efficacy of stimulants for college students with ADHD and help prevent stimulant misuse among college students without ADHD. The working hypothesis is that stimulants, compared to baseline and placebo conditions, will improve executive functioning for college students with ADHD but not for college students without ADHD. Improvements on executive functioning measures (e.g., CPT-IP, Spatial Span) will be examined through 2 (ADHD vs. non-ADHD) x 3 (Baseline, Placebo, Stimulant) repeated measures ANOVAs. Follow-up analyses will include paired comparisons. Expected outcomes are to confirm these hypotheses and demonstrate the need for further study of stimulants. If confirmed, the results will provide pilot data for a larger NIH grant proposal aimed at further examining the acute effects of stimulants (i.e., improved cognitive functioning with stimulants) and comparing them to the acute effects of physical exercise (i.e., improved cognitive functioning immediately after exercise). The investigators expect this outcome to have an important positive impact because it can help support stimulant medication as an effective treatment for college students with ADHD (DuPaul et al., 2012). Additionally, demonstration that stimulants do not improve executive functioning for college students without ADHD can be used to help prevent and discourage stimulant misuse and diversion on college campuses (Hartung et al., 2013).

The purpose of this study is to use a program called Regulating Together (RT), a remote, non-pharmacologic intervention to treat symptoms of emotion dysregulation in children and adolescents with Tuberous Sclerosis Complex (TSC) and TSC-Associated Neuropsychiatric Disorder (TAND). Read Less

Pain management in pediatric patients presents a difficult challenge. Unlike adults, pediatric patients often cannot communicate their pain management needs clearly. This is especially true in patients with cerebral palsy (CP), who often have concomitant developmental delay, intellectual disability and verbal limitations. Current literature indicates pain as a common experience for children with CP but has been understudied in this population. Moreover, inadequate post-operative pain control can result in negative physiologic and psychological complications and lead to poor surgical outcomes. Currently, perioperative pain management following orthopaedic procedures in pediatric patients follows traditional protocols that rely on the administration of opioid medications despite their known adverse side effects including nausea, vomiting, itching, constipation, urinary retention, confusion, and respiratory depression. Epidural anesthesia is a key modality in traditional pain management for pediatric patients with CP given its proven efficacy in decreasing pain and managing spasticity. Yet, administering epidural anesthesia in this patient population poses several risks including damage to preexisting intrathecal baclofen pumps, iatrogenic infection, and technically demanding insertion given high rates of concomitant neuromuscular scoliosis. Alternatively, multimodal analgesic injections theoretically offer an efficacious adjunct to traditional pain management protocols with a lower risk profile. Preliminary data from our study group's pilot randomized control trial comparing the safety and efficacy of a multimodal surgical site injection to placebo showed decreased pain scores and narcotic consumption postoperatively in this patient population. Based on these promising results, the objective of this randomized control trial is to evaluate the efficacy of a multimodal surgical site injection compared to epidural anesthesia for postoperative pain control following operative management of hip dysplasia in pediatric patients with CP.
