RESUMEN

OBJECTIVE: To evaluate the effect of curricular content reduction in an integrated course sequence spanning 3 years of a Doctor of Pharmacy curriculum on student examination scores and course grades. METHODS: This 2-year, prepost study compared student overall average and final examination scores and overall course grades after the transition from a 5-day to a 4-day week of an integrated learning experience (ILE) course sequence. In addition, an anonymous, optional 23-item survey was distributed to first to third year pharmacy students asking about the 4-day week change, how they utilized the non-ILE day, and additional demographic and social characteristics to identify factors influencing success on examination and course performance during the 4-day week. RESULTS: There were 533 students included in the overall analysis, with no significant differences in overall course grades in the 5-day vs 4-day week. Examination scores were not significantly different after the transition, except in 2 of 12 courses where scores were higher and final examination scores were not significantly different, except for higher final examination scores in 1 course during the 5-day week. Significant positive influencers of top quartile of examination performance included prepharmacy grade point average ≥ 3.5, age 25 to 29 years, and prepharmacy coursework at the parent institution, whereas using the non-ILE day primarily to sleep negatively influenced outcomes. CONCLUSION: Curricular density is a prevalent problem and addressing it at a program level is essential. Reducing curricular content and hours at our institution did not adversely impact student examination and course performance and slight improvement was noted in some areas.

RESUMEN

Prematurity is among the leading risks for poor neurocognitive outcomes. The brains of preterm infants show alterations in structure and electrical activity, but the underlying circuit mechanisms are unclear. To address this, we performed a cross-species study of the electrophysiological activity in the visual cortices of prematurely born infants and mice. Using electroencephalography (EEG) in a sample of healthy preterm (N = 29) and term (N = 28) infants, we found that the maturation of the aperiodic EEG component was accelerated in the preterm cohort, with a significantly flatter 1/f slope when compared to the term infants. The flatter slope was a result of decreased spectral power in the theta and alpha bands and was correlated with the degree of prematurity. To determine the circuit and cellular changes that potentially mediate the changes in 1/f slope after preterm birth, we used in vivo electrophysiology in preterm mice and found that, similar to infants, preterm birth results in a flattened 1/f slope. We analyzed neuronal activity in the visual cortex of preterm (N = 6) and term (N = 9) mice and found suppressed spontaneous firing of neurons. Using immunohistochemistry, we further found an accelerated maturation of inhibitory circuits. In both preterm mice and infants, the functional maturation of the cortex was accelerated, underscoring birth as a critical checkpoint in cortical maturation. Our study points to a potential mechanism of preterm birth-related changes in resting neural activity, highlighting the utility of a cross-species approach in studying the neural circuit mechanisms of preterm birth-related neurodevelopmental conditions.

RESUMEN

Leptinotarsa decemlineata, the Colorado potato beetle (CPB), is a herbivore that primarily feeds on Solanum foliage and is a global pest of the potato agricultural industry. Potato breeding through cross-hybridization with CPB-resistant wild relatives is used for genetic improvement. The wild species Solanum okadae was demonstrated to deter CPB feeding in choice and no choice feeding assays. Liquid chromatography-mass spectrometry (LC-MS) was used for comparative metabolite profiling between S. okadae and CPB-susceptible domesticated potato variety, Solanum tuberosum cv. Shepody. Major foliar metabolites detected were steroidal glycoalkaloids (SGAs) with tomatine and dehydrotomatine produced in S. okadae and solanine and chaconine in S. tuberosum cv. Shepody. Cardiac glycosides were also detected in the foliar metabolite profile of S. okadae but not S. tuberosum cv. Shepody. This class of plant compounds have known insecticidal activity through inhibition of animal Na+/K+ ATPase. Thin-layer chromatography (TLC) separation of foliar extracts also provided evidence for cardiac glycosides in S. okadae. Cardiac glycosides are known inhibitors of Na+/K+ ATPase, and foliar extracts from S. okadae (OKA15), but not S. tuberosum cv. Shepody, were able to inhibit the Na+/K+ ATPase of CPB. These findings suggest a novel mechanism of plant resistance against CPB involving production of cardiac glycosides in S. okadae.

RESUMEN

ABSTRACT: Treatment-resistant hypertension (TRH) is associated with increased cardiovascular risks and progression of chronic kidney disease. The pathophysiology of TRH is multifactorial, including overactivity of the renin-angiotensin-aldosterone system and sympathetic nervous system, endothelial dysfunction, and volume overload. Endothelin-1 is a vasoconstrictive peptide that causes neurohormonal and sympathetic activation, increased aldosterone synthesis and secretion, endothelial dysfunction, vascular hypertrophy and remodeling, and fibrosis. Endothelin-1 acts through 2 receptors, ETA and ETB. Activation of ETA receptors in vascular smooth muscle cells results in vasoconstriction, whereas ETB receptor activation results in vasoconstriction in the vascular smooth muscle cells and vasodilation through nitric oxide release in endothelial cells. Aprocitentan is novel, oral, dual endothelin-receptor antagonist that has demonstrated a more favorable tolerability and safety profile in early clinical trials compared with other endothelin-receptor antagonists studied. Phase 2 trial data support a significant reduction in blood pressure compared to placebo and similar blood pressure reduction compared to a moderately dosed angiotensin-converting enzyme inhibitor in patients with essential hypertension. An ongoing phase 3 randomized clinical trial is evaluating aprocitentan's efficacy and safety in patients with TRH receiving multiple antihypertensives. Additional research is needed to determine aprocitentan's role in therapy, but this agent may be a suitable treatment option for TRH.

RESUMEN

BACKGROUND AND PURPOSE: Self-evaluation is a critical step in professional development. Peer evaluation may enhance student learning and help peer evaluators recognize their own limitations. However, these evaluations may not accurately assess performance. This study's purpose is to evaluate differences between faculty, self-, and peer evaluations of student journal club (JC) presentations during advanced pharmacy practice experiences (APPEs). EDUCATIONAL ACTIVITY AND SETTING: Student JC presentations for three APPE sites were identified between May 2015 and April 2018 and included if at least one faculty, self-, and peer evaluation were complete. Overall grades and individual rubric ratings were compared. FINDINGS: Seventy-four students had complete data sets. The mean overall scores for JC presentations were 82.72%, 86.05%, and 91.01% for faculty, self-, and peer evaluations, respectively. Self-evaluation ratings were significantly higher than faculty on each domain, except for "presentation and communication skills" (mean difference: -0.2, p = .034) and "ability to answer questions" (mean difference: -0.1, p = .247). Linear regression showed a statistically significant relationship between self-evaluation and faculty evaluation ratings for ability to answer questions (beta = 0.5, p < .001). Peer evaluation ratings were significantly higher than faculty and self-evaluations (p < .05). SUMMARY: Faculty scores on JC presentations completed during APPEs were lower compared to student evaluations of themselves and their peers. Further incorporation of self- and peer evaluation throughout pharmacy school curricula may improve student competence in performing these evaluations. Formal training is needed to improve students' ability to complete self and peer evaluations.

RESUMEN

Objective. To develop and establish validity for a grading rubric to evaluate diabetes subjective, objective, assessment, plan (SOAP) note writing on primary care (PC) advanced pharmacy practice experiences (APPEs), and to assess reliability and student perceptions of the rubric. Methods. Ten PC APPE faculty members collaborated to develop a rubric to provide formative and summative feedback on three written SOAP notes per APPE student over a 10-month period. Correlation analyses were conducted between rubric scores and three criterion variables to assess criterion-related validity: APPE grades, Pharmaceutical Care Ability Profile Scores, and Global Impression Scores. Inter-rater and intra-rater reliability testing were completed using Cohen's kappa and Intraclass Correlation Coefficients (ICC). Student perceptions were assessed through an anonymous student survey. Results. Fifty-one students and 167 SOAP notes were evaluated using the final rubric. The mean score significantly increased from the first to second SOAP note and from the first to third SOAP note. Statistically significant positive correlations were found between final rubric scores and criterion variables. The ICC for inter-rater reliability was fair (.59) for final rubric scores and excellent for intra-rater reliability (.98 to1.00). Students responded that the rubric improved their ability (84.9%) and confidence (92.4%) to write SOAP notes. Conclusion. The rubric may be used to make valid decisions about students' SOAP note writing ability and may increase their confidence in this area. The use of the rubric allows for greater reliability among multiple graders, supporting grading consistency.

RESUMEN

Force (F) reduction is reported with myotendinous junction (MTJ) manipulation. Autogenic inhibition reflex (AIR) activation is supposed to be the main mechanism. Still, its role remains unclear. The study aimed at assessing the effects of MTJ direct inhibitory pressure (DIP) on neuromuscular activation and F in the elbow flexor (agonist) and extensor (antagonist) muscles. After maximum voluntary contraction (MVC) assessment, thirty-five participants randomly performed submaximal contractions at 20, 40, 60, and 80% MVC. Electromyographic (EMG), mechanomyographic (MMG), and F signals were recorded. Protocol was repeated under (i) DIP (10-s pressure on the biceps brachii MTJ) with the elbow at 120° (DIP120), (ii) DIP with the elbow at 180° (DIP180), and (iii) without DIP (Ctrl). Electromechanical delay (EMD) components, EMG and MMG root mean square (RMS), and rate of force development (RFD) were calculated. Independently from the angle, DIP induced decrements in MVC, RFD, and RMS of EMG and MMG signals and lengthened the EMD components in agonist muscles (P<0.05). The DIP-induced decrease in F output of the agonist muscles seems to be possibly due to a concomitant impairment of the neuromuscular activation and a transient decrease in stiffness. After DIP, the antagonist muscle displayed no changes; therefore, the intervention of AIR remains questionable.

RESUMEN

Optimization of glycemic control is a fundamental aspect of diabetes management, and rates of diabetes-related microvascular complications are significantly decreased when glycemic control is improved. Currently, > 5 million Americans require insulin therapy to manage their diabetes, and this number is expected to multiply as the prevalence of type 2 diabetes increases secondary to several factors. The distinct pharmacodynamic properties of each insulin product help physicians decide which type of insulin is the most appropriate for each patient. The method of delivery that will ensure both patient and provider satisfaction must also be carefully considered. Insulin pen devices are designed to provide a convenient and easy means of insulin administration for the patient and can be divided into 2 categories: the reusable, durable pen, and the disposable, prefilled pen. These insulin pen devices are an alternative to the traditional insulin vial-and-syringe method and offer many advantages. Insulin pens have also been found to be less painful than the vial-and-syringe method and are often associated with greater patient preference and social acceptability. As a result, this method of insulin delivery may ultimately help to improve glycemic control and should be considered when prescribing insulin products.

RESUMEN

INTRODUCTION: Current guidelines for the diagnosis and management of asthma suggest that patients perform peak expiratory flow (PEF) measurements while standing; however, recent literature suggests this may not be necessary. The purpose of this study was to determine the impact of patient position on PEF measurements. METHODS: A randomized observational analysis of PEF measurements for 211 patients in sitting and standing positions was performed. The highest PEF measurement from tests performed with correct technique in both the sitting and standing position was compared. RESULTS: Overall, PEF measurements did not significantly differ between the sitting and standing positions (506 +/- 2 L/min versus 508 +/- 2 L/min; P = .45). No differences were seen between mean PEF measurements in the sitting or standing positions for either women or men, nor were there significant differences between mean PEF values for the sitting and standing positions in participants who reported a history of asthma. CONCLUSIONS: PEF measurements do not significantly differ based on sitting or standing measurements among healthy participants. Based on the results of this study it may not be necessary for the patient to stand while performing PEF measurements. Further study among patients with asthma is warranted.

RESUMEN

The prevalence of diabetes mellitus (DM) in the elderly population currently represents almost one-half of the overall diabetic population. Treatment of DM often requires a multidrug regimen that includes insulin therapy; however, due to concomitant comorbidities such as dementia, vision loss, neuropathies, poor mobility, and poor manual dexterity, elderly patients may be at increase risk for hypoglycemia and other dosing errors that are associated with insulin administration. Insulin pen devices have been shown to provide more reliable, accurate, and simplified dosing, and therefore may be a safer, easier, and more acceptable method of insulin delivery in the elderly population. This review will describe the various insulin pen devices available today, as well as discuss the potential advantages of these devices in the elderly population.
