MRI/PET multimodal imaging of the innate immune response in skeletal muscle and draining lymph node post vaccination in rats.

The goal of this study was to utilize a multimodal magnetic resonance imaging (MRI) and positron emission tomography (PET) imaging approach to assess the local innate immune response in skeletal muscle and draining lymph node following vaccination in rats using two different vaccine platforms (AS01 adjuvanted protein and lipid nanoparticle (LNP) encapsulated Self-Amplifying mRNA (SAM)). MRI and 18FDG PET imaging were performed temporally at baseline, 4, 24, 48, and 72 hr post Prime and Prime-Boost vaccination in hindlimb with Cytomegalovirus (CMV) gB and pentamer proteins formulated with AS01, LNP encapsulated CMV gB protein-encoding SAM (CMV SAM), AS01 or with LNP carrier controls. Both CMV AS01 and CMV SAM resulted in a rapid MRI and PET signal enhancement in hindlimb muscles and draining popliteal lymph node reflecting innate and possibly adaptive immune response. MRI signal enhancement and total 18FDG uptake observed in the hindlimb was greater in the CMV SAM vs CMV AS01 group (↑2.3 - 4.3-fold in AUC) and the MRI signal enhancement peak and duration were temporally shifted right in the CMV SAM group following both Prime and Prime-Boost administration. While cytokine profiles were similar among groups, there was good temporal correlation only between IL-6, IL-13, and MRI/PET endpoints. Imaging mass cytometry was performed on lymph node sections at 72 hr post Prime and Prime-Boost vaccination to characterize the innate and adaptive immune cell signatures. Cell proximity analysis indicated that each follicular dendritic cell interacted with more follicular B cells in the CMV AS01 than in the CMV SAM group, supporting the stronger humoral immune response observed in the CMV AS01 group. A strong correlation between lymph node MRI T2 value and nearest-neighbor analysis of follicular dendritic cell and follicular B cells was observed (r=0.808, P<0.01). These data suggest that spatiotemporal imaging data together with AI/ML approaches may help establish whether in vivo imaging biomarkers can predict local and systemic immune responses following vaccination.

Practical opportunities for pharmacists to optimize psychotropic medication use among foster youth.

OBJECTIVES: Bring awareness of the health disparity of higher psychotropic medication use among foster youth, describe barriers to optimizing foster children's medication regimen from the perspective of people who work closely with them, and propose practical strategies to empower pharmacists to identify and care for this vulnerable population. SUMMARY: A total of 11 focus groups with 72 participants were conducted. Although the discussion guide did not specifically address pharmacists or pharmacies, participants in 9 groups referenced them. The pharmacist-related comments fell under 2 main themes: (1) Pharmacists are recognized as medication experts and their expertise is valued. (2) Those caring for foster youth observe barriers to optimal medication therapy that are unique to children in the foster care system. Practical considerations include providing education to social workers, offering unit-dose packaging, offering delivery, and being a resource during transitions of care. CONCLUSION: Higher rates of psychotropic medication use among foster youth in the United States have raised concern for several decades. Pharmacists are recognized as medication experts by the foster care team, creating an opportunity for pharmacists to become more involved in optimizing psychotropic medication use among foster youth.

Characterization of Chronic Multiclass Psychotropic Polypharmacy and Psychotherapy in Foster Care Youth in a State Medicaid Population.

BACKGROUND: Foster youth have higher rates of psychotropic medication use and concurrent multiclass psychotropic polypharmacy compared with nonfoster youth. However, less is known about the extent of multiclass psychotropic polypharmacy after adjusting for patient factors associated with psychotropic medication use OBJECTIVES: To (a) compare psychotropic medication use and psychotherapy use by youth in foster care to those not in foster care in the Oklahoma Medicaid population across various sociodemographic and clinical factors, and (b) determine if patient-related characteristics are associated with high levels of concurrent multiclass psychotropic polypharmacy. METHODS: This cross-sectional, retrospective analysis was conducted using paid prescription, outpatient, and inpatient Oklahoma Medicaid administrative claims from calendar year 2016. Foster youth and adolescents aged 20 years or younger were identified (n = 9,325) and compared with the general Oklahoma Medicaid population of the same age (n = 639,868). Descriptive statistics highlight baseline demographic and clinical differences between the 2 groups. Multivariable logistic regression was used to determine if covariates were associated with concurrent multiclass psychotropic polypharmacy. A subgroup analysis of foster youth taking at least 1 psychotropic medication was also performed to determine factors associated with the highest level of concurrent multiclass psychotropic polypharmacy. RESULTS: Foster care was associated with higher odds of concurrent multiclass psychotropic polypharmacy regardless of presence of psychotherapy. Among the subgroup of foster youth taking at least 1 psychotropic medication, attention deficit hyperactivity disorder medications were the most commonly prescribed medication class, followed by antidepressants and anxiolytics when use was not chronic. However, at the highest level of chronic multiclass psychotropic polypharmacy (4-5 chronic concurrent medications), antipsychotics rose to the top, and anxiolytics were the least likely to be prescribed. Overall, the foster care population had the highest proportion of individuals with concurrent multiclass psychotropic polypharmacy (9.2% vs. 1.9%, P < 0.0001). The highest level of chronic multiclass psychotropic polypharmacy was more likely to occur in males (OR = 1.66, 95% CI = 1.40-1.96) and patients living in group homes (OR = 4.13, 95% CI = 2.02-8.44) or foster homes (OR = 1.66, 95% CI = 1.25-2.19). Being overweight or obese was associated with an 83% higher odds of being at the highest level of concurrent multiclass psychotropic polypharmacy (95% CI = 1.27-2.64). CONCLUSIONS: Despite higher psychotherapy use, high rates of psychotropic medication use and concurrent multiclass psychotropic polypharmacy in foster youth remain a concern for policymakers. Patterns observed at different levels of concurrent multiclass psychotropic polypharmacy may be key to identifying youth who require additional monitoring. Future research exploring factors associated with higher levels of psychotropic concurrent multiclass psychotropic polypharmacy in foster youth can lead to actionable interventions and important policy changes.

A novel use of photovoice methodology in a leadership APPE and pharmacy leadership elective.

BACKGROUND AND PURPOSE: The purpose of this article is to describe and assess the effectiveness of an innovative teaching approach in an advanced pharmacy practice experience (APPE) and leadership elective. EDUCATIONAL ACTIVITY AND SETTING: Three cohorts of students [(2014: n = 14), (2015: n = 17), (2016: n = 19)] were introduced to the photovoice (PV) method in their leadership APPE. PV required students to take, present, and discuss photographs within their cohorts. PV was used as a teaching method with the intention that the process would compel students to be involved in leadership development throughout experiential rotations, participate in discussions related to leadership development, and engage in creative activity. Group discussions from the class of 2014 were recorded and transcribed. Students from all cohorts were asked to participate in an electronic survey containing items based on PV learning objectives. All students were asked to participate in semi-structured interviews about PV. FINDINGS AND DISCUSSION: The inductive coding method was used to identify themes from discussion transcripts. Analysis of themes revealed 51.5% of the PV photographs related to emotional intelligence. Development of others and strong teams were themes represented in 44.3% of photographs. Survey data indicated all respondents agreed PV was a valuable method to describe learning in leadership. Interview coding revealed themes related to emotional intelligence and development of teams. SUMMARY: The PV method was an effective teaching tool in a leadership APPE and elective course. PV is a teaching method to be utilized in a variety of experiential learning environments to better enhance the professional development of pharmacy students.

Evaluation of serum prolactin levels in intellectually disabled patients using antipsychotic medications.

BACKGROUND: Patients with intellectual disabilities may be treated with antipsychotic medications for a variety of diagnoses. Use of this category of medication can increase prolactin levels and place the patient at risk for sexual dysfunction and lower bone mineral density. The proposed mechanism of action is affinity for the dopamine receptor. Use of bromocriptine, a dopamine receptor antagonist, was proposed to attenuate hyperprolactinemia. OBJECTIVES: The objectives of this study were to (1) review serum prolactin (PRL) elevations associated with the use of antipsychotic (AP) medications in an intellectually disabled adult population and (2) determine if any association existed between the level of elevation and AP used. PATIENTS AND METHODS: Medical records for adult patients at two Oklahoma facilities for the intellectually disabled were reviewed to evaluate prolactin levels for individuals prescribed antipsychotics. A linear regression model was used to evaluate the relationship between prolactin levels with intellectual disability level, bromocriptine use, demographics, and antipsychotic. RESULTS: 73 (n = 53 males, n = 20 females) patients met criteria. The average age was 41.2 years. Nearly 70% of the patients had severe to profound levels of disability. 77% were prescribed second generation antipsychotics; 19% received first generation agents. Two variables, gender and bromocriptine use, were found to be significant predictors of prolactin levels. Mean prolactin level for females was 44 ng/mL (normal range: 4-30 ng/mL, males = 4-23 ng/mL). Patients who did not receive bromocriptine had mean levels of 23 ng/mL. No significant difference in prolactin levels was found for type of AP. CONCLUSIONS: Mean prolactin levels for females were significantly higher than for males. Both sexes were found to have higher-than-normal levels. Use of bromocriptine was associated with higher prolactin levels. In this population of patients, the type of AP used had no significance on prolactin levels.
