ABSTRACT

BACKGROUND: The Extended Care Health Option (ECHO) Program is a TRICARE program aimed at reducing the disabling effects of chronic medical conditions for beneficiaries of the Department of Defense (DoD) healthcare program. However, little is known about military-connected children enrolled in the program. OBJECTIVE/HYPOTHESIS: The aim of this study was to examine the demographic makeup of pediatric ECHO beneficiaries and their healthcare claims data. This is the first study to evaluate healthcare utilization of this subset of military dependents. METHODS: A cross-sectional study was performed evaluating ECHO enrolled pediatric beneficiaries and their health service utilization during 2017-2019. TRICARE claims and military treatment facility (MTF) encounter data were utilized to evaluate health service utilization and identify the most frequently reported ICD-10-CM and CPT codes associated with care for this population. RESULTS: Of the 2,001,619 dependents aged 0-26 years who received medical care in the Military Health System (MHS) during 2017-2019, 21,588 individuals (1.1%) were enrolled in ECHO. The majority of encounters (65.4%) were provided in the MTFs. Inpatient visits, therapeutic services, and in-home nursing care were the top utilized private sector care services. Outpatient visits encompassed 94.8% of healthcare encounters, and neurodevelopmental disorders were the top principal diagnoses among ECHO beneficiaries. CONCLUSIONS: With the increasing prevalence of children with medical complexity and developmental delay, the pediatric TRICARE beneficiaries eligible for ECHO will likely continue to rise. Improving services and supports for military children with special healthcare needs is needed to maximize their developmental trajectory.

ABSTRACT

The aim of this study was to understand COVID-19 vaccine perceptions and decision-making among a racially/ethnically diverse population of pregnant and lactating women in the Midwest. Pregnant female participants (N = 27) at least 18 years. or older living in the Midwest were recruited to participate in a maternal voices survey. A mix-methods approach was used to capture the perceptions of maternal voices concerning the COVID-19 vaccine. Participants completed an online survey on COVID-19 disease burden, vaccine knowledge, and readiness for uptake. A total of 27 participants completed the Birth Equity Network Maternal Voices survey. Most participants were African American (64%). Sixty-three percent intend to get the vaccine. Only 25% felt at-risk for contracting COVID-19, and 74% plan to consult their provider about getting the COVID-19 vaccine. At least 66% had some concerns about the safety of the vaccine. Participants indicated a willingness to receive the COVID-19 vaccine, especially if recommended by their provider. We found little racial/ethnic differences in perceptions of COVID-19 and low vaccine hesitancy.

ABSTRACT

The Ras-related protein Cell division cycle 42 (Cdc42) is important in cell-signaling processes. Protein interactions involving Cdc42 occur primarily in flexible "Switch" regions that help regulate effector binding. We studied the kinetics of intrinsic GTP hydrolysis reaction in the absence and presence of a biologically active peptide derivative of a p21-activated kinase effector (PBD46) for wt Cdc42 and compared it to the Switch 1 variant Cdc42(T35A). While the binding of PBD46 to wt Cdc42 results in complete inhibition of GTP hydrolysis, this interaction in Cdc42(T35A) does not. Comparison of the crystal structure of wt Cdc42 in the absence of effector (1AN0.pdb), as well as the NMR structure of wt Cdc42 bound to an effector in the Switch 1 region (1CF4.pdb) ( www.rcsb.org ) suggests that the orientation of T(35) with bound Mg(2+) changes in the presence of effector, resulting in movement of GTP away from the catalytic box leading to the inhibition of GTP hydrolysis. For Cdc42(T35A), molecular dynamics simulations and structural analyses suggest that the nucleotide does not undergo the conformational shift observed for the wt Cdc42-effector interaction. Our data suggest that change in dynamics in the Switch 1 region of Cdc42 caused by the T35A mutation (Chandrashekar, et al. 2011, Biochemistry, 50, p. 6196) fosters a conformation for this Cdc42 variant that allows hydrolysis of GTP in the presence of PBD46, and that alteration of the conformational dynamics could potentially modulate Ras-related over-activity.
