RESUMEN

OBJECTIVE: To determine the relationship between first-year retention and variables related to professional engagement and professional, academic, and personal identities. METHODS: This study evaluated data from 3 cohorts of students at a private 0-6 college of pharmacy. A theoretical and conceptual framework linking professional identity and retention informed the study. Professional engagement scores from the first semester of pharmacy school served as a surrogate of professional identity. Grade point average (GPA) and traditional demographic variables (eg, gender, race/ethnicity, in-state resident) served as surrogates of academic and personal identities, respectively. Logistic regression models were used to determine the relationship between first-year retention and identity variables. RESULTS: Belonging, a domain of professional engagement, was positively related to first-year retention. In multivariable models, belonging and cumulative GPA were associated with increased odds of retention, while in-state status was associated with decreased odds. In separate models for those with GPA ≥3.00, and<3.00, belonging was associated with first-year retention in both. Belonging was also associated with first-semester retention, but not second-semester retention. CONCLUSION: A decision to leave a Doctor of Pharmacy program is complex, but the vast majority of the literature in pharmacy education appears to focus most intently on academic variables, including GPA. This study demonstrates that belonging, an important element in professional identity formation, remains related to first-year retention, even after controlling for grades and other personal variables. This finding unearths several theory-informed gems and strategies that educators may employ to enhance retention.

RESUMEN

OBJECTIVES: To explore the landscape of mentorship within professional associations in pharmacy academia, including reviewing available literature and describing currently available programs within the American Association of Colleges of Pharmacy, and recommend key considerations for the development of mentorship programs within professional associations. FINDINGS: A literature review of mentorship programs within professional associations for pharmacy academics was conducted, with a total of 5 articles identified and summarized. Additionally, a survey was conducted to determine the landscape of available mentorship programs within American Association of Colleges of Pharmacy affinity groups to capture unpublished experiences. Information regarding common characteristics and assessment methods was collected for groups that have mentorship programs, while needs and barriers were collected for those who did not. SUMMARY: Literature, while limited, supports positive perceptions of mentorship programs within professional associations. Based on the responses and working group experience, several recommendations are proposed for mentorship program development, including the need for clearly defined goals, relevant program outcomes, association support to reduce redundancies and promote participation, and, in some cases, implementation of an association-wide program to ensure access to mentorship.

RESUMEN

INTRODUCTION: Cardiovascular fat is a novel risk factor that may link to dementia. Fat volume and radiodensity are measurements of fat quantity and quality, respectively. Importantly, high fat radiodensity could indicate healthy or adverse metabolic processes. METHODS: The associations of cardiovascular fat (including epicardial, paracardial, and thoracic perivascular adipose tissue [PVAT]) quantity and quality assessed at mean age of 51 with subsequent cognitive performance measured repeatedly over 16 years of follow-up were examined using mixed models among 531 women. RESULTS: Higher thoracic PVAT volume was associated with a higher future episodic memory (ß[standard error (SE)] = 0.08 [0.04], P = 0.033), while higher thoracic PVAT radiodensity with lower future episodic (ß[SE] = -0.06 [0.03], P = 0.045) and working (ß[SE] = -0.24 [0.08], P = 0.003) memories. The latter association is prominent at higher volume of thoracic PVAT. DISCUSSION: Mid-life thoracic PVAT may have a distinct contribution to future cognition possibly due to its distinct adipose tissue type (brown fat) and anatomical proximity to the brain circulation. HIGHLIGHTS: Higher mid-life thoracic perivascular adipose tissue (thoracic PVAT) volume is related to a better future episodic memory in women. Higher mid-life thoracic PVAT radiodensity is related to worse future working and episodic memories. Negative association of high thoracic PVAT radiodensity with working memory is prominent at higher thoracic PVAT volume. Mid-life thoracic PVAT is linked to future memory loss, an early sign of Alzheimer's disease. Mid-life women's epicardial and paracardial fat are not related to future cognition.

RESUMEN

Harsh realities in pandemic fatigue, burnout, inequities, and isolation are impacting academic pharmacy. Mentoring programs, especially inter-institutional programs such as those provided within the Sections and Special Interest Groups (SIGs) of the American Association of Colleges of Pharmacy (AACP), may combat some of these issues. Unfortunately, year after year, Academy members continue to request information from these groups on mentoring, whether it be the opportunity to pair up, for advice on how to be better mentors, or for guidance on how to develop a program on mentoring for the Sections and SIGs without an existing program. The need for authentic mentoring is vital to the success and retention of faculty and staff within the Academy. Therefore, it may be appropriate to take a closer look at why, despite ongoing mentoring programs scattered within AACP Sections and SIGs, these programs are unable to fulfill the needs of participants.

RESUMEN

BACKGROUND: Acute burn pain is difficult to manage, and poorly managed pain can lead to deleterious consequences such as post-traumatic stress disorder, prolonged recovery, chronic pain and long-term dependence on opioids. Understanding the role of nursing in promoting self-efficacy and minimizing opioid use is valuable. It is unknown whether strategic efforts aimed at enhancing patient self-efficacy will improve pain managment and lessen opioid requirements in the adult burn population. AIM: The aim of this study was to examine the effect of a multi-modal, interdisciplinary pain management strategy on coping self-efficacy, pain scores, and opioid use in adult burn patients in the acute care setting. METHOD: A quasi-experimental pre-test/post-test design was employed in an American Burn Association (ABA) verified burn center in the Pacific Northwestern United States. Data were collected prospectively for a 6-month period on 44 burn patients. The comparison group received usual care (n = 28), and the intervention received a pain management protocol (n = 16). Coping self-efficacy was measured on admission and at discharge in both groups using the Coping Self-Efficacy Scale. Numeric pain scores and opioid use in morphine milligram equivalents were averaged for each participant. Burn nurse perceptions were gathered via an anonymous electronic survey post data collection in February 2021. RESULTS: There were no significant differences in measured coping self-efficacy, pain scores, or opioid use between the intervention and comparison groups. A significant positive correlation was found between length of stay, size of burn, and coping self-efficacy and problem focused self-efficacy. Burn nurses reported increased use of nonpharmacologic adjuncts since protocol implementation. CONCLUSION: Nonpharmacologic adjuncts are more likely to be used consistently when protocolized. There is also evidence to support that certain aspects of self-efficacy may be enhanced during acute phase of burn care.

RESUMEN

With COVID-19 now pervasive, identification of high-risk individuals is crucial. Using data from a major healthcare provider in Southwestern Pennsylvania, we develop survival models predicting severe COVID-19 progression. In this endeavor, we face a tradeoff between more accurate models relying on many features and less accurate models relying on a few features aligned with clinician intuition. Complicating matters, many EHR features tend to be under-coded degrading the accuracy of smaller models. In this study we develop two sets of high-performance risk scores: (i) an unconstrained model built from all available features; and (ii) a pipeline that learns a small set of clinical concepts before training a risk predictor. Learned concepts boost performance over the corresponding features (C-index 0.858 vs. 0.844) and demonstrate improvements over (i) when evaluated out-of-sample (subsequent time periods). Our models outperform previous works (C-index 0.844-0.872 vs. 0.598-0.810).

RESUMEN

Objective. For pharmacy students to successfully meet competencies related to Accreditation Council for Pharmacy Education Standards 3 and 4, it is essential for pharmacy programs to assess student progression in the affective domain. The purpose of this study was to develop and assess the validity of a situational judgment test (SJT) for evaluating student mastery of Standards 3 and 4.Methods. A multi-institutional faculty team developed an 18-item SJT that consisted of scenarios asking the respondent to rank the effectiveness of four response options mapped to Standards 3 and 4. The research team systematically reviewed the literature, created items, and deliberated until consensus was achieved. Subject matter experts (SMEs) reviewed and provided feedback on the instrument. Students from two institutions were recruited to participate in cognitive interviews about the finalized instrument. Cognitive interview data were analyzed to identify themes.Results. After edits were made to the instrument based on SME feedback, students (n=18) in the cognitive interviews identified item length as a concern and commented on item/response clarity and comprehensiveness. Data from the cognitive interviews were used to modify the SJT to reduce the length and clarify items. The result was two shorter versions of the instrument, both with similar mapping to all elements in Standards 3 and 4.Conclusion. Early steps in validating the SJT suggested that the instrument may be a promising tool to assess student progression in the affective domain. The SJT instrument is intended to provide evidence of student pharmacist development that occurs in the didactic, experiential, and co-curricular portions of pharmacy education. The instrument can serve as one part of a comprehensive assessment plan.

RESUMEN

INTRODUCTION: Professional health care associations present a unique opportunity for formal mentorship programs, with membership often spanning a variety of experiences, professional ranks, and institutions. However, scarce literature describes the role of professional associations in the development and assessment of mentoring programs. This paper describes development of the American Association of Colleges of Pharmacy Women Faculty Special Interest Group (SIG) mentoring program and characterizes the impact of the program. METHODS: The task force collaboratively developed the mission, vision, and structure of the mentoring program, posted the program description on the SIG's electronic forum, and called for mentors and mentees via an online survey asking for matching preferences. The task force reviewed responses and designated matches. Participants were emailed match information and a guidance document. The program was assessed at three, six, and 12 months via electronic survey. RESULTS: The program matched 43 mentors with 77 mentees, with each mentor assigned one to three mentees. At the three- and six-month assessments, 89% and 87% of respondents, respectively, indicated they had met with their mentor/mentee. At the 12-month assessment, 86% of mentor respondents and 80% of mentee respondents stated the mentoring program met their needs/expectations. Career goal development, work/life integration, and difficult work situations were the most frequently discussed topics. Most participants stated they would continue to serve as a mentor/mentee in a future cycle and recommend other faculty members participate. CONCLUSIONS: Results from three-, six-, and 12-month assessments indicated a positive impact of developing a nationwide, organizational, cross-discipline mentoring program.

RESUMEN

OBJECTIVE: To study the relationship between hydroxychloroquine (HCQ) use and new-onset atrial fibrillation in patients with systemic lupus erythematosus (SLE). METHODS: A retrospective cohort of adult patients with SLE was constructed from December 1, 2014 to May 30, 2017. Patients were categorized as either HCQ users or nonusers. The primary outcome was incident atrial fibrillation. Secondary outcomes included incident ventricular arrhythmias (composite of ventricular tachycardia, ventricular fibrillation, or torsades de pointes). Outcomes were adjudicated by review of the electronic health record. Statistical analyses included simple and multivariable logistic regression tests to estimate the association between HCQ use and incident atrial fibrillation after adjusting for relevant confounders. Propensity score matching analysis was completed. RESULTS: Our study included 1,647 patients with SLE, of which 917 were HCQ users and 730 were nonusers. A total of 23 atrial fibrillation events occurred, including 3 in HCQ users and 20 in nonusers. Logistic regression analysis showed an odds ratio (OR) of 0.12 (95% confidence interval [95% CI] 0.034-0.39, P = 0.0005) for incident atrial fibrillation and 2.39 (95% CI 0.25-23.0, P = 0.45) for ventricular arrhythmias. Results remained significant in the fully adjusted and propensity score-matched models. CONCLUSION: In this exploratory study, HCQ use was associated with an 88% decrease in the risk of incident atrial fibrillation in patients with SLE. Considering the increased cardiovascular risk in SLE, incorporation of HCQ into the regimen may be beneficial for both disease manifestations and reducing the risk of atrial fibrillation. Further studies would be needed to confirm the antifibrillatory benefit of this relatively safe and low-cost medication.

RESUMEN

PURPOSE: The treatment of distal femur fractures with extensive metaphyseal comminution is frequently complicated by high rates of nonunion and varus collapse. Dual plating with lateral and medial locking plates for these types of fractures has shown promising results in the recent literature. We hypothesize that dual plating of comminuted distal femur fractures leads to higher union rates and lower revision rates compared to an isolated lateral locking plate. METHODS: A retrospective medical chart review between January 2015 and December 2017 was conducted. Inclusion criteria included patients 18 years of age and older who sustained a complex distal femur fracture (AO/OTA 33-C2/33-C3 or periprosthetic fracture with significant metaphyseal comminution) and at least 6 months of follow up. Patients with simple fracture patterns, alternative fixation methods, and inadequate follow up were excluded. All patients in the single plating group were treated with a lateral distal femoral locking plate using a lateral approach. In the patients treated with dual plating, an extensile parapatellar approach was utilized for fracture reduction and placement of an adjunctive medial plate. Demographic information, fracture types, injury severity score (ISS), medical comorbidities, type of surgical fixation, union rates, complications, knee range of motion, time to follow up, and need for revision surgery were extrapolated from the medical charts for analysis. RESULTS: Twenty-one patients were included in the study. Thirteen patients underwent single plate fixation and 8 underwent dual plate fixation. There were no significant differences in demographics, number of co-morbidities, fracture classification, or ISS between single and dual plate groups (p > 0.05 for all). There was a statistically significant difference in union rates between the single plate group (6 nonunions, 4 unions, and 3 delayed unions) and the dual plate group, with no nonunions or delayed unions (p = 0.0049). Although not statistically significant, 4 patients treated with single plating underwent revision ORIF, compared to none in the dual plating group (p = 0.13). There were no significant differences in time to follow up, time to full weight bearing, or infection rates (p > 0.1 for all). CONCLUSION: Based on these results, the medial and lateral locked plating technique demonstrates a higher union rate, with possible lower rates of revision surgery, compared to a single lateral plate in highly comminuted distal femur fractures. LEVEL OF EVIDENCE: Level 3. Retrospective Cohort Study.

RESUMEN

OBJECTIVE: To determine independent risk factors for inappropriate antibiotic prescribing for acute respiratory tract infections (ARIs) in internal medicine (IM) residency-based primary care offices. PATIENTS AND METHODS: A retrospective study was conducted to measure antibiotic prescribing rates, and multivariable analysis was utilized to identify predictors of inappropriate prescribing among patients presenting to IM residency-based primary care office practices. Patients with an office visit at either of 2 IM residency-based primary care office practices from January 1, 2016, through December 31, 2016, with a primary encounter diagnosis of ARI were included. RESULTS: During the study period, 911 unique patient encounters were included with 518 for conditions for which antibiotics were considered always inappropriate. Antibiotics were not indicated in 85.8% (782 of 911) of encounters. However, antibiotics were prescribed in 28.4% (222 of 782) of these encounters. Inappropriate antibiotic prescribing occurred in 111 of 518 (21.4%) encounters for conditions for which antibiotics are always inappropriate. Using multivariable logistic regression analysis to assess for independent risk factors when adjusted for other potential risk factors for office visits at which antibiotics were not indicated, IM resident-associated visits (odds ratio, 0.25; 95% CI, 0.18-0.36) was the only variable independently associated with lower risk of inappropriate antibiotic prescribing. CONCLUSION: For ARI visits at which antibiotics were not indicated, IM resident comanagement was associated with lower rates of inappropriate prescribing.

RESUMEN

BACKGROUND: Higher perivascular adipose tissue (PVAT) contributes to adverse physiologic alterations in the vascular wall, and thus could potentially limit normal physical function later in life. We hypothesize that higher PVAT volume at midlife is prospectively associated with slower gait speed later in life, independent of overall adiposity and other risk factors. METHODS: Participants from the Study of Women's Health Across the Nation (SWAN) cardiovascular fat ancillary study were included. PVAT volume around the descending aorta was quantified using existing computed tomography scans at midlife, while gait speed was measured after an average of 10.4 ± 0.7 years. RESULTS: Two hundred and seventy-six women (aged 51.3 ± 2.8 years at PVAT assessment) were included. Mean gait speed was 0.96 ± 0.21 m/s. Adjusting for study site, race, education level, menopausal status, and length of descending aorta at PVAT assessment, and age, body mass index, difficulty paying for basics, overall health and smoking status at gait speed assessment, a higher midlife PVAT volume was associated with a slower gait speed later in life (p = .03). With further adjustment for presence of any comorbid conditions by the time of gait speed assessment, the association persisted; every 1SD increase in log-PVAT was associated with 3.3% slower gait speed (95% confidence interval: 0.3-6.3%; p = .03). CONCLUSION: Greater PVAT in midlife women may contribute to poorer physical function in older age supporting a potential role of midlife PVAT in multiple domains of healthy aging. Additional research is needed to fully elucidate the physiologic changes associated with PVAT that may underlie the observed associations.

RESUMEN

BACKGROUND AND AIMS: Fat radiodensity, measured via CT Hounsfield units (HU), is a potential marker of fat quality. We sought to determine the cross-sectional associations of total heart fat (TAT) and aortic perivascular fat (PVAT) radiodensity with cardiovascular risk factors, coronary artery calcification (CAC), and aortic calcification (AC) in midlife women. METHODS: Fat radiodensity, CAC, and AC were quantified using CT scans. A total of 528 women (mean age: 50.9 ±â€¯2.9 years; 37% Black) were included in analyses. RESULTS: Women in the lowest TAT radiodensity tertile were more likely to have adverse cardiovascular risk factors. Independent of cardiovascular risk factors, women in the middle and high TAT radiodensity tertiles were less likely to have CAC (OR (95% CI): 0.32 (0.18, 0.59); 0.43 (0.24, 0.78), respectively) compared with women in the lowest TAT radiodensity tertile. Although adjusting for BMI attenuated the overall association, women in the middle TAT radiodensity tertile remained at significantly lower odds of CAC when compared to the low radiodensity tertile, 0.47 (0.24, 0.93), p=0.03. No significant associations were found for PVAT radiodensity and calcification measures in multivariable analysis. CONCLUSIONS: Lower TAT radiodensity was associated with a less favorable cardiometabolic profile. Women with mid-range TAT radiodensity values had a lower odds of CAC presence, independent of CVD risk factors and BMI. More research is necessary to understand radiodensity as a surrogate marker of fat quality in midlife women.

RESUMEN

BACKGROUND AND PURPOSE: Mentoring programs, a practical tool commonly used by universities, can serve to help new students adapt to challenging college life. Peer mentorship offers the potential for professional development of student pharmacists. EDUCATIONAL ACTIVITY AND SETTING: The Raabe College of Pharmacy at Ohio Northern University implemented a peer mentoring program in 2014. This study evaluates the impact of that program on new student pharmacists. A post-program survey was completed evaluating students' career perception, emotional stability, academic success, and student perception of the program's influence on these areas. FINDINGS: The results indicated that 71.7% of respondents found the mentoring program helpful in their transition to college, and that 60.4% of respondents would "somewhat likely" or "extremely likely" stay active in the mentoring program. DISCUSSION: Peer mentorship may serve as a tool to assist student acclimation to the expectations of a professional degree program. SUMMARY: It was concluded that the pharmacy mentorship program at the Raabe College of Pharmacy at Ohio Northern is making a positive impact on first-year students by engaging them in the pharmacy program and aiding their transition from high school to college.

RESUMEN

Perivascular adipose tissue (PVAT) influences vascular function and pathology. We present a protocol using micro-computed tomography (microCT), a novel imaging technique typically used for hard biological tissue, to characterize the temporal and spatial development of aorta PVAT and luminal plaque soft tissue. Apolipoprotein E deficient (ApoE) and C57Bl/6J (control) mice were fed a high fat western diet up to 30 weeks. 3D microCT reconstructions were used to quantify: 1) vascular wall volume, a surrogate measure of remodeling, was greater in ApoE, 2) aorta PVAT volume was reduced in ApoE, 3) plaque volumes increased over time in ApoE, 4) plaque development co-localized with luminal ostia, origins of branching arteries, which traveled through areas of greatest PVAT volume, 5) qualitatively, the same arteries showed evidence of increased tortuosity in ApoE. This study reflects the potential of microCT analyses to assess vascular wall, PVAT and arterial trajectory modifications in relevant animal models. Abbreviations: PVAT: perivascular adipose tissue; ApoE: apolipoprotein E deficient mouse strain; Control: C57Bl/6J mouse strain; PTA: 0.3% phosphotungstic acid; microCT: micro-computed tomography; CV: cardiovascular; CVD: cardiovascular disease; IQR: interquartile range; PPARγ: peroxisome proliferator activated receptor - gamma; VV: vasa vasorum; 3D: three dimensional.

RESUMEN

Differential proteomic analysis (comparative quantitative proteomics) is a robust quantitative technique used to detect and identify the proteome of selected tissues. The expression levels (upregulated vs. downregulated) of proteins in tissue samples that differ by experimental design or anatomic location are determined by a series of assays including (1) 2D difference gel electrophoresis (2D-DiGE), (2) protein spot picking based on a priori thresholds, (3) Mass Spectrometry, and (4) follow-up Western Blot for antibody validation (Chen et al., Mol Cell Proteomics 14:2466-2478, 2015). Differential proteomic analysis is a perfect method for analyzing a heterogeneous tissue such as adipose tissue with a composition spectrum consisting of white to brown adipocytes along with a stromal vascular fraction dependent on anatomical location and inflammation. The adipose tissue proteomic protocol outlined here was successful in identifying differentially expressed proteins both significantly upregulated and downregulated between the experimental and control groups (Shields et al., Pulm Circ 6:586-596, 2016).

RESUMEN

Pulmonary arterial hypertension (PAH) is a rare disease characterized by significant vascular remodeling within the lung. Clinical computed tomography (CT) scans are routinely used to aid in PAH diagnosis. Animal models, including the Sugen-hypoxic rat model (SU/hyp), of PAH closely mimic human PAH development. We have previously used micro-computed tomography (microCT) to find extensive right lung vascular remodeling in the SU/hyp. We hypothesized that the individual right lung lobes may not contribute equally to overall lung vascular remodeling. Sprague-Dawley rats were subjected to a subcutaneous injection of vascular endothelial growth factor receptor blocker (Sugen 5416) and subsequently exposed to chronic hypoxic conditions (10% O2) for three weeks. Following perfusion of the lung vasculature with an opaque resin (Microfil), the right lung lobes were microCT-imaged with a 10-µm voxel resolution and 3D morphometry analysis was performed separately on each lobe. As expected, we found a significantly lower ratio of vascular volume to total lobe volume in the SU/hyp compared with the control, but only in the distal lobes (inferior: 0.23 [0.21-0.30] versus 0.35 [0.27-0.43], P = 0.02; accessory: 0.27 [0.25-0.33] versus 0.37 [0.29-0.43], P = 0.06). Overall, we observed significantly fewer continuous blood vessels and reduced vascular density while having greater vascular lumen diameters in the distal lobes of both groups ( P < 0.05). In addition, the vascular separation within the SU/hyp lobes and the vascular surface area to volume ratio were significantly greater in the SU/hyp lobes compared with controls ( P < 0.03). Results for the examined parameters support the overall extensive vascular remodeling in the SU/hyp model and suggest this may be lobe-dependent.

RESUMEN

BACKGROUND AND AIMS: Women with systemic lupus erythematosus (SLE) have an increased risk of cardiovascular disease (CVD). Perivascular adipose tissue (PVAT) surrounds the vascular wall, is associated with CVD risk factors, and may contribute to premature CVD in SLE. We previously found greater volumes of aortic PVAT associated with aortic calcification (AC) in female SLE patients. There is recent evidence that not only volume but adipose density may also be indicative of inflammation. We hypothesized that female SLE patients would have a difference in aPVAT quality associated with AC that is independent of volume. METHODS: Aorta PVAT quality was evaluated using the average radiodensity (density) of adipose tissue-specific Hounsfield Units (-190 to -30 HU) within each clinical CT scan of CVD-free, age-/race-matched SLE women (n = 143) and healthy controls (HC, n = 143). RESULTS: Aorta PVAT density was significantly higher in SLE (mean (SD): (-83.6 (1.9) HU) versus HC (-84.1 (1.8) HU), p=0.03). Increasing aPVAT volume was correlated with denser aPVAT in SLE (ρ, p-value: 0.75,<0.0001) and HC (0.74,<0.0001). Increasing AC score (log) was correlated with denser aPVAT for SLE (0.31, 0.0005) and HC (0.23, 0.008). In linear regression, denser aPVAT was more strongly associated with AC score in SLE (ß (SE): 0.445 (0.11), p<0.0001) versus HC (0.335 (0.12), p=0.006) independent of age, circulating inflammatory markers, CVD risk factors and BMI (p<0.05), but was attenuated with aPVAT volume (p=0.3). CONCLUSIONS: Denser aPVAT is associated with aPVAT volume and AC in SLE women. Adjusting for aPVAT volume attenuated the detected association between aPVAT density and AC, which may be indicative of adipose dysfunction.
