Adapting to Unprecedented Times: Community Clinician Modifications to Parent-Child Interaction Therapy during COVID-19.

Parent-Child Interaction Therapy (PCIT) is an evidence-based practice that effectively prevents and treats child disruptive behaviors and child physical maltreatment and reduces parenting stress. PCIT was adapted for telehealth delivery, internet-delivered PCIT (iPCIT), before the COVID-19 pandemic but was not widely implemented until the rapid transition to telehealth during stay-at-home orders. To understand how clinicians adapted PCIT during COVID-19, we followed up on a previous study investigating community clinician adaptations of PCIT pre-COVID-19 using the Lau et al. (2017) Augmenting and Reducing Framework. Clinicians (N = 179) who responded to the follow-up survey and reported delivering PCIT remotely completed a quantitative measure of adaptations at both time points (Fall 2019; Summer 2020) to assess how adaptations to PCIT changed following lockdown measures. Clinicians (n = 135) also provided qualitative descriptions of adaptations made early in the COVID-19 pandemic. Clinicians in the full sample were 74.3% Non-Hispanic White and 14% Latinx. Most clinicians had a master's degree (66.5%), were licensed (80.4%), and were PCIT-certified (70.4%). Paired samples t-tests showed that clinicians reported similar levels of augmenting t(179) = -0.09, p=.926) and reducing adaptations t(179) = -0.77, p=.442) at both time points. Unlike quantitative findings, qualitative findings indicated that clinicians described engaging in many types of adaptations in response to the pandemic. Clinicians discussed engaging in augmenting adaptations by extending treatment length and integrating other practices into treatment. Clinicians also discussed engaging in reducing adaptations. Implications and future directions will be discussed.

An engineered dual function peptide to repair fractured bones.

Targeted drug delivery, often referred to as "smart" drug delivery, is a process whereby a therapeutic drug is delivered to specific parts of the body in a manner that increases its concentration at the desired sites relative to others. This approach is poised to revolutionize medicine as exemplified by the recent FDA approval of Cytalux (FDA approves pioneering drug for ovarian cancer surgery - Purdue University News) which is a folate-receptor targeted intraoperative near infrared (NIR) imaging agent that was developed in our laboratories. Fracture-associated morbidities and mortality affect a significant portion of world population. United states, Canada and Europe alone spent $48 billion in treating osteoporosis related fractures although this number doesn't count the economic burden due to loss in productivity. It is estimated that by 2050 ca 21 million hip fractures would occur globally which will be leading cause of premature death and disability. Despite the need for improvement in the treatment for fracture repair, methods for treating fractures have changed little in recent decades. Systemic delivery of fracture-homing bone anabolics holds great promise as a therapeutic strategy in this regard. Here we report the design of a fracture-targeted peptide comprised of a payload that binds and activates the parathyroid hormone receptor (PTHR1) and is linked to a targeting ligand comprised of 20 D-glutamic acids (D-Glu20) that directs accumulation of the payload specifically at fracture sites. This targeted delivery results in reduction of fracture healing times to <1/2 while creating repaired bones that are >2-fold stronger than saline-treated controls in mice. Moreover, this hydroxyapatite-targeted peptide can be administered without detectable toxicity to healthy tissues or modification of healthy bones in dogs. Additionally, since similar results are obtained upon treatment of osteoporotic and diabetic fractures in mice, and pain resolution is simultaneously accelerated by this approach, we conclude that this fracture-targeted anabolic peptide displays significant potential to revolutionize the treatment of bone fractures.

Lay Health Workers Engaging Latino Fathers: A qualitative study.

Behavioral Parent Training programs (BPTs) are evidence-based interventions that have been shown to be effective when implemented in various contexts and with different racial/ethnic minority families. Despite evidence showing their effectiveness within the Latinx community, disparities in access to BPTs still persist. In addition, fathers continue to show low rates of attendance and engagement despite evidence suggesting positive outcomes for the youth and family when fathers are involved in BPT treatment. Lay health workers (LHWs), community members without specialized metal health training that often live in the communities they serve, have been identified as engagement specialists that are uniquely positioned to reduce racial/ethnic disparities in access to services. The current study utilized a qualitative approach to examine this workforce's perspectives on engaging Latino fathers in parenting services in children's mental health. Qualitative themes revealed that LHWs have generally positive attitudes towards engaging Latino fathers in parenting interventions (i.e., benefits to parent-child relationship) despite experiencing barriers to engagement (e.g., culturally defined gender roles, fathers being less likely to ask for help). Themes also elucidate various engagement strategies that LHWs use to engage fathers in treatment (e.g., adapting treatment setting). Considerations for future LHW trainings and workforce development are discussed with a focus on how to incorporate cultural values in the use of father-engagement strategies.
