Does a broad-spectrum cannabidiol supplement improve performance in a 10-min cycle ergometer performance-test?

Cannabidiol (CBD) is a non-intoxicating phytocannabinoid which has been proposed to possess anti-inflammatory and analgesic properties. Given the potential for perceptions of pain to limit exercise performance, the aim of the present study was to investigate if 3 weeks of daily CBD supplementation (150 mg day-1) improved performance in a 10-min performance-trial on a cycle ergometer. In a randomized, double-blind and placebo-controlled study, 22 healthy participants (n = 11 male and n = 11 female) completed two 10-min performance trials on a WattBike cycle ergometer interspersed with a 3-week supplementation period. Supplementation involved either 150 mg day-1 oral CBD or 150 mg day-1 of a visually identical placebo (PLA). During trials, ratings of perceived exertion (RPE [6-20]), heart rate (HR) and blood lactate (BLa) were collected every 2 min. Mean power (W) was also taken throughout the exercise at each time point. All data were analyzed using two-way ANOVAs. There were no significant differences (P > 0.05) between CBD or PLA groups for mean power (W) during the 10-min performance trial. There were also no significant differences (P > 0.05) in any of the physiological or perceptual parameters (HR, BLa and RPE) between conditions. Three weeks supplementation of a broad-spectrum CBD supplement did not improve performance via any change in RPE during a 10-min time trial on a cycle ergometer, and as such, this evidence does not support the claim that broad-spectrum CBD supplements could be performance-enhancing in this exercise modality.

Adapting a community pharmacy intervention to improve medication safety.

BACKGROUND: Community pharmacies are an ideal location to address challenges of over-the-counter medication safety, yet many successful interventions are only tested in a few pharmacies without expansion, creating unrealized opportunities to improve patient care on a larger scale. Scaling up to numerous pharmacies can be challenging because each community pharmacy has unique needs and layouts and requires individualized adaptation. OBJECTIVES: This paper reports techniques for (a) adapting a community pharmacy intervention to fit the unique physical layout and patient needs of health system pharmacy sites without increasing staff workload, (b) identifying strategies to gather feedback on adaptations from stakeholders, and (c) developing materials to share with pharmacy champions for them to independently implement and sustain the intervention in their organization. PRACTICE DESCRIPTION: The study team collaborated with Aurora Pharmacy, Inc to develop an intervention designed to increase awareness of safe over-the-counter medication use for older adults. PRACTICE INNOVATION: Senior Safe, a community pharmacy-based intervention, was designed, implemented, and tested using the Exploration, Preparation, Implementation, and Sustainment implementation framework. EVALUATION METHODS: Senior Safe was adapted through pilot testing and a randomized control trial. Feedback was collected from key stakeholders, including pharmacy staff, older adults, and a research advisory group. RESULTS: A finalized version of Senior Safe, as well as an implementation package, was provided to Aurora Pharmacy to integrate into all 63 sites. CONCLUSION: This multiphase study illustrated that refining an intervention is possible and welcomed by pharmacy staff, but it requires time, resources, and funds to create an impactful, sustainable community pharmacy intervention.

Elevating Safe Use of Over-The-Counter Medications in Older Adults: A Narrative Review of Pharmacy Involved Interventions and Recommendations for Improvement.

Over-the-counter (OTC) medications are products that have been made easily accessible to allow patients to treat common ailments without a prescription and the cost of a doctor's visit. These medications are generally considered safe; however, there is still a potential for these medications to lead to adverse health outcomes. Older adults (ages 50+) are especially susceptible to these adverse health outcomes, due to age-related physiological changes, a higher prevalence of comorbidities, and prescription medication use. Many OTC medications are sold in pharmacies, which provides pharmacists and technicians with the opportunity to help guide safe selection and use for these medications. Therefore, community pharmacies are the ideal setting for OTC medication safety interventions. This narrative review summarizes the findings of pharmacy-involved interventions that promote safe OTC medication use for older adults.

Impact of an immersive, interactive medical education initiative on guideline-based retinal disease management knowledge/competence and effectual practice change.

BACKGROUND: Retinal diseases, including wet or dry age-related macular degeneration, diabetic macular edema, and diabetic retinopathy (DR), are underdiagnosed and undertreated in the United States. Clinical trials support the effectiveness of anti-vascular endothelial growth factor (anti-VEGF) therapies for several retinal conditions, but real-world data suggest underuse by clinicians, resulting in patients experiencing poorer visual outcomes over time. Continuing education (CE) has demonstrated effectiveness at changing practice behaviors, but more research is needed to understand whether CE can help address diagnostic and treatment gaps. METHODS: This test and control matched pair analysis examined pre-/post-test knowledge of retinal diseases and guideline-based screening and intervention among 10,786 healthcare practitioners (i.e., retina specialists, ophthalmologists, optometrists, primary care providers, diabetes educators, pharmacists/managed care specialists, and other healthcare providers, such as registered nurses, nurse practitioners, and physician assistants) who participated in a modular, interactive CE initiative. An additional medical claims analysis provided data on practice change, evaluating use of VEGF-A inhibitors among retina specialist and ophthalmologist learners (n = 7,827) pre-/post-education, compared to a matched control group of non-learners. Outcomes were pre-/post-test change in knowledge/competence and clinical change in application of anti-VEGF therapy, as identified by the medical claims analysis. RESULTS: Learners significantly improved knowledge/competence scores on early identification and treatment, identifying patients who could benefit from anti-VEGF agents, using guideline-recommended care, recognizing the importance of screening and referral, and recognizing the importance of early detection and care for DR (all P-values = 0.003 to 0.004). Compared with matched controls, learners' incremental total injections for anti-VEGF agents for retinal conditions increased more after the CE intervention (P < 0.001); specifically, there were 18,513 more (new) anti-VEGF injections prescribed versus non-learners (P < 0.001). CONCLUSIONS: This modular, interactive, immersive CE initiative resulted in significant knowledge/competence gains among retinal disease care providers and changes in practice-related treatment behaviors (i.e., appropriate consideration and greater incorporation of guideline-recommended anti-VEGF therapies) among participating ophthalmologists and retina specialists compared to matched controls. Future studies will utilize medical claims data to show longitudinal impact of this CE initiative on treatment behavior among specialists and impact on diagnosis and referral rates among optometrists and primary care providers who participate in future programming.

Evaluation of a Pharmacist-Driven Ambulatory Aspirin Deprescribing Protocol.

Background: Recent guidelines indicate that aspirin affords less cardiovascular protection and greater bleeding risks in adults aged > 70 years. Deprescribing potentially inappropriate medications is particularly important in older adults, as this population experiences a high risk of adverse effects and polypharmacy. Limited data are available regarding targeted aspirin deprescribing approaches by pharmacists. The objective of this study was to implement and evaluate the success and feasibility of a pharmacist-led aspirin deprescribing protocol for older adults in a primary care setting. Observations: This prospective feasibility study in a US Department of Veterans Affairs ambulatory care pharmacy setting included patients aged ≥ 70 years with documented aspirin use. We reviewed 459 patient records and determined that 110 were eligible for deprescribing. A pharmacistinitiated telephone call was attempted for each eligible patient to discuss the risks and benefits of deprescribing aspirin. The primary outcome was the proportion of patients reached for whom aspirin was discontinued. Secondary outcomes included patient rationale for declining deprescribing and the time to complete the intervention. Of 94 patients reached, 45 (48%) agreed to aspirin deprescribing, 3 (3%) agreed to dose reduction, and 29 (31%) declined the intervention. An additional 17 (18%) had previously stopped aspirin, which led to a medication reconciliation intervention. Pharmacists spent about 2 minutes per record review and 12 minutes on each encounter, including documentation. Conclusions: Implementing a pharmacist-driven aspirin deprescribing protocol in a primary care setting led to the discontinuation of inappropriate aspirin prescribing in nearly half of older adults contacted. The protocol was well accepted by collaborating physicians and feasible for pharmacists to implement, with potential for further dissemination across primary care settings.

Impact of a pilot community pharmacy system redesign on reducing over-the-counter medication misuse in older adults.

BACKGROUND: No interventions have attempted to decrease misuse of over-the-counter (OTC) medications for adults aged 65 years or older (older adults) by addressing system barriers. An innovative structural pharmacy redesign (the Senior Section) was conceptualized to increase awareness of higher-risk OTC medications. The Senior Section contains a curated selection of OTC medications and is close to the prescription department to facilitate pharmacy staff-patient engagement to reduce misuse. OBJECTIVE: This pilot study examined the Senior Section's effectiveness at influencing OTC medication misuse in older adults. METHODS: A pretest-post-test nonequivalent groups design was used to recruit 87 older adults from 3 pharmacies. Using a hypothetical scenario, the participants selected an OTC medication that was compared with their medication list and health conditions, and their reported use was compared with the product labeling. Misuse outcomes comprised drug-drug, drug-disease, drug-age, and drug-label, with 5 subtypes. Patient characteristics were compiled into a propensity score matching logistic regression model to estimate their effects on the Senior Section's association with misuse at pre- or postimplementation. RESULTS: Patient characteristics were uniform between pre- and postimplementation, and, once entered into a propensity score matching model, drug-label misuse (exceeds daily dosage) statistically significantly lessened over time (z = -2.42, P = 0.015). In addition, the Senior Section reduced drug-label misuse (exceeds single dosage) for both the raw score model (z = -6.38, P = 0.011) and the model in which the patient characteristics propensity score was added (z = -5.82, P = 0.011). Despite these limited statistical effects, misuse was found to decrease after implementation for 7 of 11 comparisons. CONCLUSION: These nascent outcomes begin providing an evidence base to support a well-conceived, pharmacy-based OTC medication-aisle redesign for reducing older adult OTC medication misuse. The Senior Section, when broadly implemented, creates permanent structures and processes to assist older adults to access risk information when selecting safer OTC medications.

Status of Legislative Efforts to Promote and Protect Breastfeeding and the Provision of Human Milk for Women Returning to Work in the First Postpartum Year.

INTRODUCTION: Women account for over 50% of the workforce in the United States with many working women being of childbearing age. The United States does not provide long paid parental leave, thus mothers who choose to breastfeed are confronted with the reality of combining breastfeeding and returning to work. Return to work is reported to negatively impact breastfeeding exclusivity and duration. While the existing federal law protects some women, not all women have legal support to breastfeed or express milk at work. Exemptions to the federal law include limitations related to the employee's status, classification of employer, total number of employees and the employer's annual revenue. This study aimed to examine existing city-level legislation protecting the rights of women to breastfeed or express milk at their place of employment during the postpartum period. MATERIALS AND METHODS: Prospective descriptive study with survey. The national sample includes the three largest cities of each state and the capital city of the United States (Washington, DC) for a total of 151 cities. The data were collected in a tiered approach with three phases: (1) assessment of city website, (2) e-mail to city mayor's office, and (3) telephone follow-up with the city's office. RESULTS: Only 2/151 (1.3%) of cities had specific legislation outlining the protections for all breastfeeding women in the workplace. CONCLUSIONS: This research demonstrates a clear need for political action to increase the number of women who have workplace regulations to protect breastfeeding.

A preliminary examination of over-the-counter medication misuse rates in older adults.

BACKGROUND: Older adults are the largest consumers of over the counter (OTC) medications. Of the older adults who are at risk of a major adverse drug event, more than 50% of these events involve an OTC medication. OBJECTIVE: To explore how older adults select and hypothetically use OTC medications and if the selected medications would be considered safe for use. METHODS: Walking interviews were conducted with 20 community-dwelling older adults in a community pharmacy. Each participant selected an OTC medication for a hypothetical pain and sleep scenario. Data were analyzed for four types of misuse: drug-drug interaction, drug-disease interaction, drug-age interaction, and excess usage. RESULTS: At least one instance of potential misuse was found in 95% of participants. For sleep medications, drug-drug interactions and drug-age interactions were more common, affecting 50% and 65% of participants respectively. The most common type of misuse noted in the pain products selected was that of drug-drug interaction, with a total of 39 occurrences, affecting 60% of the participants. CONCLUSIONS: OTC misuse is common among older adults, and it is important for older adults to seek out resources, such as a pharmacist, to help them make safe OTC decisions.

Factors associated with cervical cancer screening in a safety net population.

AIM: To identify factors associated with Papanicolaou-smear (Pap-smear) cervical cancer screening rates in a safety net population. METHODS: From January 2012 to May 2013, the use of Pap-smear was determined for all patients seen at the breast clinic in a safety net hospital. Health literacy assessment was performed using the validated Newest Vital Sign. The records of patients were reviewed to determine if they had undergone Pap-smears for cervical cancer screening. Sociodemographic information was collected included age, education, monthly income, race/ethnicity, employment, insurance status, and primary care provider of the patient. Logistic regression analysis was then performed to determine factors associated with utilization of Pap-smears. Crude and adjusted odds ratios derived from multivariate logistic regression models were calculated as well as the associated 95%CIs and P-values. RESULTS: Overall, 39% had Pap-smears in the prior 15 mo, 1377 consecutive women were seen during the study period and their records were reviewed. Significantly more patients with adequate health literacy underwent Pap-smears as compared to those with limited health literacy (59% vs 34%, P < 0.0001). In multivariate analysis, patients with adequate health literacy, younger patients, and those with later age of first live birth were more likely to undergo Pap-smears. Patients whose primary care providers were gynecologists were also significantly more likely to have Pap-smears compared to other specialties (P < 0.0001). Patients younger than 21 years or older than 65 years underwent screening less frequently (11% and 11%, respectively) than those 21-64 years (41%, P < 0.0001). Race, ethnicity, language, and insurance status were not associated with Pap-smear screening rates. CONCLUSION: Patient health literacy and primary care physician were associated with Pap-smear utilization. Development of interventions to target low health literacy populations could improve cervical cancer screening.

Fluoroquinolone susceptibility among Mycobacterium tuberculosis isolates from the United States and Canada.

BACKGROUND: There is increasing interest in the possible role of new fluoroquinolone antibiotics for treatment of tuberculosis, but widespread use of fluoroquinolones for treatment of other bacterial infections may select for resistant strains of Mycobacterium tuberculosis. METHODS: We evaluated fluoroquinolone susceptibility using the proportion method (critical ciprofloxacin concentration for susceptibility testing, 2.0 mu g/mL) in isolates obtained from patients enrolled in Tuberculosis Trial Consortium clinical trials during the period of 1995-2001 and in a referral sample of isolates sent to the Centers for Disease Control and Prevention (Atlanta, GA) during the period of 1996-2000 for additional testing, often because of drug resistance. RESULTS: Of the 1373 isolates from the clinical trials, 1324 (96%) were susceptible to isoniazid and rifampin; 2 (0.15%) of these isolates were also resistant to ciprofloxacin. Of the 1852 isolates from the referral sample, 603 (32.6%) were resistant to isoniazid and rifampin (i.e., multidrug resistant), 849 (45.7%) were resistant to >or=1 first-line drug but were not resistant to both isoniazid and rifampin, and 400 (21.6%) were susceptible to all first-line agents. Ciprofloxacin resistance was found in 33 (1.8%) of the referral-sample isolates. Most ciprofloxacin-resistant isolates (25 [75.8%]) were resistant to isoniazid and rifampin. CONCLUSIONS: Despite widespread use of fluoroquinolones for treatment of common bacterial infections, resistance among clinical isolates of M. tuberculosis in the United States and Canada remains rare, occurring primarily among multidrug-resistant strains.
