Generic entry of aromatase inhibitors and pharmaceutical access: Initiation of hormonal therapy,timeliness of initiation,and drug choice

BackgroundThe trade-offs between innovation and pharmaceutical access are central to the policy debate on drug pricing. High prices may limit access, result in medication underuse, and negatively affect outcomes. Generic drugs make treatments more affordable. Prior research measured access as utilization without a defined population that should receive certain drugs, it is unknown whether generic entry reduces underuse and thus improves access.ObjectivesTo measure changes in access (use, timeliness) with the introduction of three generic aromatase inhibitors (AIs, oral breast cancer drugs) between June 2010 and June 2011.MethodsThis population-based study included 93,650 older (65+) women diagnosed with hormone receptor-positive breast cancer between 2007 and 2013 in the Surveillance, Epidemiology and End Results-Medicare linked database. We examined changes in access with generic entry for initiation of any adjuvant hormonal therapy drug (AIs or tamoxifen) within one year of diagnosis, time from diagnosis to initiation, and choice of initial therapy.ResultsAmong 93,650 newly diagnosed breast cancer cases, 67,372 initiated one of the four drugs. With generic entry, initiation rates increased from 69.5% to 74.3%, but non-initiation remained high (up to 25.7%). After controlling for demographics, clinical factors, and insurance coverage, the probability of initiation increased by 4.6 percentage points (P < 0.001, 95%CI: [4.1,5.2]) after generic entry. With generic entry, estimated time to initiation decreased by 0.3 months (P < 0.001, 95%CI: [0.2,0.3]) from 4.1 months, and the probability of choosing AIs over tamoxifen increased by 5.9 percentage points (P < 0.001, 95%CI: [5.3,6.5]). Patterns did not substantially differ by level of cost-sharing.ConclusionsGeneric entry of AIs was associated with increased probability of receiving recommended treatments, timeliness of treatment, and the probability of receiving clinically preferred treatments. Price changes with generic entry only partially explained these improvements. High non-initiation rates after generic entry suggest prices are not the sole determinant of access.     

Social and legislative shaping of access to contraceptives and the pharmacist's role: A literature review

BackgroundDespite years of research and numerous policies, access to contraceptives in the United States remains imperfect. Largely due to lack of access to contraceptives, unintended pregnancy rates remain high.ObjectiveTo provide researchers and policy-makers with a comprehensive review of the legislative and social landscape that has shaped contraceptive access in the United States, which may help to guide future research and policies.MethodsA narrative overview of existing literature on policies and research regarding women's access to contraceptives was compiled, with a focus on the role of pharmacists.ResultsContraceptive access has been heavily influenced by laws and policies throughout the years, and disparities remain in underserved populations. Pharmacists are beginning to play a role in improving access to contraceptives through provision of contraceptives using direct pharmacy access policies.ConclusionsContinued research and new policies aimed at improving contraceptive access are warranted.     

Prevalence and forms of cannabis use in legal vs. illegal recreational cannabis markets

BackgroundRecreational or ‘non-medical cannabis’ has been legalized in several US states, and was legalized federally in Canada in October 2018. There is little comparative data on product use across jurisdictions, particularly with respect to the types of cannabis products used, which differentially impact health.MethodsData are from Wave 1 of the International Cannabis Policy Study, collected from Aug 27–Oct 7, 2018. Respondents (n = 27,024) aged 16–65 completed an online survey measuring patterns of cannabis use, quantities and routes of administration. Respondents were recruited from Canada (n = 9976) and US states that had (n = 7362) and had not (n = 9686) legalized non-medical cannabis (‘legal’ and ‘illegal’ states, respectively).ResultsPrevalence of at least daily, weekly, and monthly cannabis use were significantly higher in US ‘legal’ states (11.3%, 18.2%, 25.0%, respectively) than US ‘illegal’ states (7.4%, 11.6%, 16.8%, respectively; p<0.001) and Canada (8.9%, 14.1%, 19.0%, respectively; p ≤ 0.01). Dried herb was the dominant form of cannabis reported by past 12-month users across all jurisdictions (77.7%–80.8%). Although the amount of dried herb used per year did not differ by jurisdiction (range: 210.3–229.4 g), those in US ‘legal’ states were significantly more likely to use dried herb daily or weekly than were those in ‘illegal’ states and Canada (p<0.001). Use of cannabis concentrates, vaped oils, edibles, and drinks was more prevalent among US ‘legal’ states than ‘illegal’ states and Canada (p ≤ 0.001). Vaping dried herb was more common in both legal and illegal US jurisdictions than in Canada (p<0.05), whereas Canadians were more likely to smoke dried herb with tobacco (p<0.001).ConclusionThe prevalence of cannabis use—and use of products such as cannabis concentrates, edibles and drinks—was higher in US states that had legalized cannabis. Additional longitudinal research is required to determine whether these differences reflect causal effects of legalization or pre-existing secular trends.     

Pharmacy student’s perceptions,behaviours and attitudes toward virtual reality simulation

AimsThe definition of virtual reality simulation (VRS) used for study is the recreation of realistic simulation in a fully online situation with an immersive environment for learning an activity. The study aims to evaluate pharmacy students’ perspectives, behavioral and attitude characteristics in the process of VRS course requiring practical skills.Materials and methodsThis cross-sectional study was based on quantitative questionnaires analysis. A five-point Likert Scale (rating from 1 = Strongly Disagree; 2 = Disagree; 3 = Neutral; 4 = Agree; 5 = Strongly Agree) was utilized to measure the extent to which the students agrees on 30 statements comprised in A-E sections related to VRS. The validity and reliability of the questionnaire were studied by the Cronbach’s Alpha calculation.ResultsA total of 119 junior and senior pharmacy students, aged 18–25, participated in this study. There is no significant gender difference (P > 0.05) and grade difference (P > 0.05) in mean perception score, mean attitude score, mean behavior score and comparison score respectively. Most pharmacy students had positive perception that VRS could help them in practical ability (61.4 %), autonomous learning (68.9 %) and theoretical knowledge (61.4 %). Nevertheless, less than half the students agreed that VRS courses were indispensable (44.5 %) and needed to be increased (42.9 %). Moreover, the ‘disagree’ statement (33.6 %) exceeded ‘agree’ statement (27.7 %) about the question of whether preferring VRS courses to lab teaching. Interestingly, a significant positive correlation that was observed between mean perception score and mean attitude score (r = 0.76, p < 0.001), mean comparison (r = 0.68, p < 0.001) and mean behavior (r = 067, p < 0.001), which revealed that students who thought VRS was beneficial were more likely to accept it.ConclusionThe study highlights the need to establish an interactive, immersive and measurable VRS courses. It is suggested that good interaction between the faculty and student, technology improvement and blended programmatic assessment should be involved in challenges for implementing VRS courses.     

The role of the pharmacist in mental health: An investigation of the impact of pharmacist-led interventions on psychotropic medication adherence in patients with diabetes

ObjectiveTo evaluate the impact of targeted telepharmacist mental health adherence interventions for patients with type 2 diabetes.MethodsThis retrospective review involved the analysis of a telepharmacist-led mental health intervention. The subjects included: patients aged 18 years or more with type 2 diabetes, enrolled in an adherence service and who had been prescribed psychotropics. Psychotropic medication adherence was measured using the proportion of days covered (PDC) 6 months before and after the telepharmacist-led medication intervention.ResultsA total of 8167 patients (67% women), with a mean age of 63 ± 11 years, were included in the study. Most alerts for psychotropics were for selective serotonin reuptake inhibitors (SSRIs) (53%, n = 4334), selective norepinephrine reuptake inhibitors (SNRIs) (22%, n = 1775), second-generation antipsychotics (11%, n = 909), and bupropion (10%, n = 782). Alerts with the greatest volume of PDCs (above 85%) at postintervention follow up included SSRIs (51%, n = 2228), SNRIs (50%, n = 884), and second-generation antipsychotics (47%, n = 424). Before the alert, the mean PDC was 66% ± 12% across all medications studied. Post intervention, the mean PDC rose to 79% ± 19. A paired t-test revealed statistically significant improvement in adherence overall, with the greatest change observed in these alert groups: SSRIs (P < 0.001), alpha-2 antagonist (P < 0.001), SNRIs (P < 0.001), and bupropion (P < 0.001).ConclusionThis retrospective review showed that pharmacist-led targeted, adherence interventions greatly improved psychotropic medication adherence in adult patients with type 2 diabetes. Future work is warranted to investigate the impact on type 2 diabetes medication adherence and health markers (e.g., HbA1c values) in larger and more diverse populations of patients with comorbid type 2 diabetes and a mental health condition.     

High salt diet may promote progression of breast tumor through eliciting immune response

ObjectiveDietary patterns are believed to regulate tumor progression by altering the tumor microenvironment. Of note, a high salt diet is a risk factor for various diseases. However, the role of high salt intake in the progression of cancers remains unknown.MethodsWe constructed an in vivo high salt diet model in MMTV-PyVT mice with spontaneous tumor-forming properties to explore the role of a high salt diet in the progression of breast cancer as well as the modulation of the tumor microenvironment. Also, in vitro experiments were performed to understand the mechanism.ResultsHigh salt diet accelerated the development (P < 0.05) and lung metastasis (P < 0.05) of breast cancer in MMTV-PyVT mice, compared to the normal diet model. Moreover, higher frequency of Th17 cells in circulation, tumor tissue and draining lymph node tissue were observed in the high salt diet model (P < 0.05 for all). In vitro, co-culture with Th17 cells facilitated the proliferation, migration and invasion of MCF-7 human breast cancer cells, while these enhanced aggressive behaviors could be reversed by application of 1,25-vitamin D₃ which could inhibit the differentiation of Th17 cells (P < 0.001 for all). In vitro, co-culture with Th17 cells activated MAPK signaling in MCF-7 cells (P < 0.001 for all). Consistently, activated MAPK/ERK signaling was observed by immunohistochemistry in breast cancer cell nodes in the high salt diet model (P < 0.05 for all). Mechanistically, higher level of IL-17F could be detected in breast tumors and serum from the high salt diet model through qRT-PCR and ELISA (P < 0.05 for all). IL-17F treatment facilitated the proliferation, migration and invasion of MCF-7 human breast cancer cells and activated MAPK/ERK signaling in MCF-7 cells (P < 0.001 for all). Moreover, the tumor-promoting function induced by Th17 cells and IL-17F could be inhibited by the administration of ERK inhibitor (sch772894) (P < 0.001 for all). Lastly, high concentration NaCl-induced Th17 cells promoted the proliferation, migration and invasion of MCF-7 human breast cancer cells and activated MAPK/ERK signaling in MCF-7 cells which could be inhibited by neutralizing anti-IL-17F (P < 0.001 for all).ConclusionHigh salt intake accelerates the growth of breast cancer and facilitates lung metastasis, as well as increases the level of Th17 cells. Increased Th17 cells might promote the growth of breast cancer via the secretion of IL-17F to activate the MAPK signaling pathway in breast cancer cells.     

Association between graduates' factors and success rate on the Saudi Pharmacist Licensure Examination: A single-Institution cross-sectional study

IntroductionThe Saudi Pharmacists Licensure Examination’s (SPLE) initial results were revealed in February 2020, which showed enormous inconsistency with the passing rates. Hence, we aimed to investigate the predictors of pharmacy graduates’ success rate on the SPLE of a single-college in Saudi Arabia.MethodsIn a cross-sectional study of 2019-graduates, data were collected via-phone interviews and retrieved from the college’s database. Graduates’ data were retrieved from the college’s database, which includes high school grade point average (GPA), General Aptitude Test, Scholastic Achievement Admission Test, preparatory year GPA, pharmacy GPA, and all courses' grades. The data collected via-phone interview includes information that was not recorded in the college’s database, such as date of birth, SPLE score, and the number of SPLE attempts. We only included students who agreed to be interviewed and had attempted the SPLE at least once. We developed a prediction model using correlational analyses and stepwise multiple linear regression to examine graduates’ factors in predicting success on the SPLE.ResultsOut of the 149 graduates, 105 fulfilled the inclusion criteria. Around 84% of them passed the SPLE. Correlation analyses showed a significant direct correlation between preparatory year GPA and pharmacy GPA with SPLE scores (r = 0.228, P = 0.0193 and r = 0.533, P < 0.0001, respectively). In addition, the results showed that all of the four SPLE content areas were positively correlated with SPLE scores (P < 0.0001). The stepwise multivariable regression showed that being a male graduate and scoring high-grade points in pharmacology and therapeutics courses were significantly associated with high SPLE scores (P = 0.0053, P = 0.0256, and P = 0.0001, respectively).ConclusionThis single cross-sectional study found that being a male, pharmacology GPA, and therapeutics GPA were significantly associated with a higher SPLE score. Further studies should focus on the GPA cut off below which we should give remediation to improve SPLE passing rate.     

Gabapentin reduces postoperative pain and opioid consumption in patients who underwent lumbar laminectomy

BackgroundPostoperative pain management solely with opioids elevates the risk of opioid-related adverse events during hospitalization and after discharge from the hospital. Clinical trials have demonstrated gabapentinoids as viable adjunctive treatments for spinal surgeries. However, only a few practice-based studies have examined the efficacy of gabapentin as an opioid-sparing agent for patients undergoing lumbar laminectomy in rural hospital settings.ObjectiveTo determine the effects of gabapentin on opioid consumption and pain perception in patients who underwent lumbar laminectomy at a rural community hospital.MethodsData were collected by retrospective chart reviews of 99 patients who underwent lumbar laminectomy at Yavapai Regional Medical Center from January 1, 2017, to July 1, 2019. The patients were stratified into 2 groups: those who were taking gabapentin as outpatients before surgery and were continued on the same dose postoperatively (n = 50, gabapentin group) and those who were not taking gabapentin preoperatively or postoperatively (n = 49, usual-treatment group). The primary end points were opioid consumption in morphine milligram equivalents (MME) and pain for 24 hours postsurgery.ResultsOutcomes from the mixed-model analysis of variance showed significant main effects of group and time for opioid consumption in MME (F_1,97 = 4.3, P < 0.05 and F_3,291 = 133.9, P < 0.001, respectively) and numerical pain scale scores (F_1,99 = 4.0, P < 0.05 and F_3,241 = 21.4, P < 0.001, respectively) and group-time interaction for opioid consumption in MME (F_3,291 = 2.6, P = 0.05). Post hoc analyses showed that opioid consumption in MME was significantly lower in the gabapentin group than in the usual-treatment group for the first 6 hours postoperatively. The pain scores were significantly lower in the gabapentin group than in the usual-treatment group across all time periods.ConclusionPatients on gabapentin showed reductions in pain perception and postoperative opioid consumption. The results extend the findings from randomized trials to a real-world clinical setting. These data support using gabapentin in conjunction with opioids for pain management of patients undergoing lumbar laminectomy.
