Seeking information and services associated with reproductive health among rural Peruvian young adults: exploratory qualitative research from Amazonas, Peru.

BACKGROUND: Sexual and reproductive health (SRH) literacy allows young adults to make informed decisions about health outcomes. In Peru, roughly one fifth of the population lives in rural areas, and little is known about where young adults in rural areas get their SRH information. The aim of this study was to identify what motivates and influences young adults to seek information and care related to SRH in three rural communities in the highlands of Northern Peru. METHODS: Five gender-stratified focus group discussions with a total of 24 participants, and nine follow-up interviews were conducted to generate in-depth narrative data and triangulate data from the target group. Participants were women and men aged 18-24. The focus group discussions and interviews explored sources of reproductive health information, the role of informal social networks, barriers to care, and primary health concerns of the target population. RESULTS: Main findings include: (1) The two greatest perceived SRH risks were unwanted pregnancy and abnormal discharge; (2) There appears to be limited concern about HIV or other sexually transmitted infections in the narratives; (3) There is a low quality of information concerning SRH, with discrepancies between the genders; (4) A broad spectrum of sources for SRH information were cited, including Internet, traditional healers, and specialized care; and varied by gender and life experience; (5) Having trust in the information source was the primary variable associated with uptake of services and/or access to information for both men and women. However, men reported more embarrassment around seeking services and information, whereas women faced more physical barriers. CONCLUSIONS: There is a lack of SRH information among young adults in some communities in the northern highlands of Peru. Both schools and health centers were noted as being trusted and established information sources for all genders so could be a key resource to explore as a way to disseminate information.

A Comparative Analysis of the Demographics and Zip Codes of Patients Seen at the Indiana University Student Outreach Clinic.

Within a small geographic area, Marion County contains a stark spectrum of health outcomes and socioeconomic statuses. The Indiana University Student Outreach Clinic (IUSOC) serves as a safety net provider, offering free health and social services in the Near Eastside neighborhood of Indianapolis. The aim of this study was to characterize the demographics and geographic distribution of the IUSOC's patient population. From January to September 2023, 612 patients visited the IUSOC, and 460 self-identified as Marion County residents. 63.9% of patients were between 45 and 64 years old. 66.8% were Non-Hispanic (NH) Black, and 23.3% were Hispanic. 18.9% spoke Spanish and had limited English proficiency. Based on the Distressed Communities Index (DCI), 58.7% lived in "Distressed" zip codes, indicating economic vulnerability and disparities. The zip code with the greatest number of IUSOC patients had the highest rate of uninsured adults in Marion County. IUSOC patients are primarily middle-aged minorities who live in zip codes with low socioeconomic rankings by DCI. This information can be used to improve community resource referral pathways in the clinic.

Infection and inflammation stimulate expansion of a CD74+ Paneth cell subset to regulate disease progression.

Paneth cells (PCs), a specialized secretory cell type in the small intestine, are increasingly recognized as having an essential role in host responses to microbiome and environmental stresses. Whether and how commensal and pathogenic microbes modify PC composition to modulate inflammation remain unclear. Using newly developed PC-reporter mice under conventional and gnotobiotic conditions, we determined PC transcriptomic heterogeneity in response to commensal and invasive microbes at single cell level. Infection expands the pool of CD74+ PCs, whose number correlates with auto or allogeneic inflammatory disease progressions in mice. Similar correlation was found in human inflammatory disease tissues. Infection-stimulated cytokines increase production of reactive oxygen species (ROS) and expression of a PC-specific mucosal pentraxin (Mptx2) in activated PCs. A PC-specific ablation of MyD88 reduced CD74+ PC population, thus ameliorating pathogen-induced systemic disease. A similar phenotype was also observed in mice lacking Mptx2. Thus, infection stimulates expansion of a PC subset that influences disease progression.

Building effective intervention models utilizing big data to prevent the obesity epidemic.

INTRODUCTION: The exposome consists of factors an individual is exposed to across the life course. The exposome is dynamic, meaning the factors are constantly changing, affecting each other and individuals in different ways. Our exposome dataset includes social determinants of health as well as policy, climate, environment, and economic factors that could impact obesity development. The objective was to translate spatial exposure to these factors with the presence of obesity into actionable population-based constructs that could be further explored. METHODS: Our dataset was constructed from a combination of public-use datasets and the Center of Disease Control's Compressed Mortality File. Spatial Statistics using Queens First Order Analysis was performed to identify hot- and cold-spots of obesity prevalence; followed by Graph Analysis, Relational Analysis, and Exploratory Factor Analysis to model the multifactorial spatial connections. RESULTS: Areas of high and low presence of obesity had different factors associated with obesity. Factors associated with obesity in areas of high obesity propensity were: poverty / unemployment; workload, comorbid conditions (diabetes, CVD) and physical activity. Conversely, factors associated in areas where obesity was rare were: smoking, lower education, poorer mental health, lower elevations, and heat. DISCUSSION: The spatial methods described within the paper are scalable to large numbers of variables without issues of multiple comparisons lowering resolution. These types of spatial structural methods provide insights into novel variable associations or factor interactions that can then be studied further at the population or policy levels.

Non-invasive Cardiac Output Monitoring and Assessment of Fluid Responsiveness in Children With Shock in the Emergency Department.

Introduction: The assessment of fluid responsiveness is important in the management of shock but conventional methods of assessing fluid responsiveness are often inaccurate. Our study aims to evaluate changes in objective hemodynamic parameters as measured using electrical cardiometry (ICON® monitor) following the fluid bolus in children presenting with shock and to evaluate whether any specific hemodynamic parameter can best predict fluid responsiveness among children with shock. Materials and Methods: We conducted a prospective observational study in children presenting with shock to our emergency department between June 2020 and March 2021. We collected the parameters such as heart rate (HR), respiratory rate (RR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and hemodynamic data such as cardiac output CO), cardiac index (CI), index of contractility (ICON), stroke volume (SV), stroke index (SI), corrected flow time (FTC), systolic time ratio (STR), variation of index of contractility (VIC), stroke volume variation (SVV), systemic vascular resistance (SVR), and thoracic fluid content (TFC) using the ICON monitor before and after fluid bolus (FB). We assessed percent change (Δ) and used paired-sample Student's t-test to compare pre- and post-hemodynamic data and Mann-Whitney U-test to compare fluid responders and non-responders. P-Values < 0.05 were considered statistically significant. Results: We recorded 42 fluid interventions in 40 patients during our study period. The median IQR age was 10.56 (4.8, 14.8) years with male/female ratio (1.2:1). There was a significant decrease in ΔRR [-1.61 (-14.8, 0); p = 0.012], ΔDBP [-5.5 (-14.4, 8); p = 0.027], ΔMAP [-2.2 (-11, 2); p = 0.018], ΔSVR [-5.8 (-20, 5.2); p = 0.025], and ΔSTR [-8.39 (-21, 3); p = 0.001] and significant increase in ΔTFC [6.2 (3.5, 11.4); p = 0.01] following FB. We defined fluid responders by an increase in SV by ≥10% after a single FB of 20 ml/kg crystalloid. Receiver operating curve analysis revealed that among all the parameters, 15% change in ICON had an excellent AUC (0.85) for the fluid responsiveness. Conclusion: Our study showed significant changes in objective hemodynamic parameters, such as SVR, STR, and TFC following FB in children presenting with shock. A 15% change in ICON had an excellent predictive performance for the fluid responsiveness among our cohort of pediatric shock.

RAB11A-mediated YAP localization to adherens and tight junctions is essential for colonic epithelial integrity.

Within the intestinal epithelium, regulation of intracellular protein and vesicular trafficking is of utmost importance for barrier maintenance, immune responses, and tissue polarity. RAB11A is a small GTPase that mediates the anterograde transport of protein cargos to the plasma membrane. Loss of RAB11A-dependent trafficking in mature intestinal epithelial cells results in increased epithelial proliferation and nuclear accumulation of Yes-associated protein (YAP), a key Hippo-signaling transducer that senses cell-cell contacts and regulates tissue growth. However, it is unclear how RAB11A regulates YAP intracellular localizations. In this report, we examined the relationship of RAB11A to epithelial junctional complexes, YAP, and the associated consequences on colonic epithelial tissue repair. We found that RAB11A controls the biochemical associations of YAP with multiple components of adherens and tight junctions, including α-catenin, ß-catenin, and Merlin, a tumor suppressor. In the absence of RAB11A and Merlin, we observed enhanced YAP-ß-catenin complex formation and nuclear translocation. Upon chemical injury to the intestine, mice deficient in RAB11A were found to have reduced epithelial integrity, decreased YAP localization to adherens and tight junctions, and increased nuclear YAP accumulation in the colon epithelium. Thus, RAB11A-regulated trafficking regulates the Hippo-YAP signaling pathway for rapid reparative response after tissue injury.

Changes in microarchitecture of atherosclerotic calcification assessed by 18F-NaF PET and CT after a progressive exercise regimen in hyperlipidemic mice.

BACKGROUND: Despite the association of physical activity with improved cardiovascular outcomes and the association of high coronary artery calcification (CAC) scores with poor prognosis, elite endurance athletes have increased CAC. Yet, they nevertheless have better cardiovascular survival. We hypothesized that exercise may transform vascular calcium deposits to a more stable morphology. METHODS: To test this, hyperlipidemic mice (Apoe-/-) with baseline aortic calcification were separated into 2 groups (n = 9/group) with control mice allowed to move ad-lib while the exercise group underwent a progressive treadmill regimen for 9 weeks. All mice underwent blood collections and in vivo 18F-NaF µPET/µCT imaging both at the start and end of the exercise regimen. At euthanasia, aortic root specimens were obtained for histomorphometry. RESULTS: Results showed that, while aortic calcification progressed similarly in both groups based on µCT, the fold change in 18F-NaF density was significantly less in the exercise group. Histomorphometric analysis of the aortic root calcium deposits showed that the exercised mice had a lower mineral surface area index than the control group. The exercise regimen also raised serum PTH levels twofold. CONCLUSION: These findings suggest that weeks-long progressive exercise alters the microarchitecture of atherosclerotic calcium deposits by reducing mineral surface growth, potentially favoring plaque stability.

Value of Systematic Approach to Assess Health-System Pharmacy Services.

Description Health-system pharmacy leaders are tasked with determining key staffing decisions based on evolving patient care needs and present-day staffing capacity. A systematic approach to evaluate patient care needs, current model and potential gaps enables leaders to allocate resources in patient care need expansions or sudden fluctuations of patient volumes. Resource management, preparedness and ongoing maintenance form principles used by pharmacy leaders to create an optimal operational environment and elevate clinical pharmacy services. Use of this approach for multiple sites of care across a large network of health systems resulted in identification and improvement in pharmacist coverage and retention of clinical pharmacy services in a critical time of economic uncertainty. Hospitals working toward expanding to 24/7 pharmacist coverage may also consider this systematic approach to elucidate their needs.

Y-site Administration of Imipenem/Cilastatin/Relebactam With Common Intravenous Medications.

PURPOSE: Imipenem/cilastatin/relebactam has shown efficacy in complicated intra-abdominal and urinary tract infections in the RESTORE IMI-1 study, and it was recently approved by the US Food and Drug Administration. A press release announced that another Phase III study (RESTORE IMI-2) in patients with hospital-acquired and ventilator-associated pneumonia has met the primary end point. Critically ill patients with multidrug-resistant infections are expected to receive several pharmaceutical intravenous drugs while admitted in hospitals, warranting the need for Y-site compatibility studies. This study was conducted to evaluate the physical compatibility of imipenem/cilastatin/relebactam for injection during Y-site administration with common injectable intravenous medications. METHODS: Imipenem/cilastatin/relebactam was prepared to the concentration of 5 mg/mL, and other intravenous tested drugs were reconstituted as per the package inserts. Y-site was simulated as a 2-drug combination by mixing 5 mL of each in a glass tube, with reversing of the order of mixing; physical characteristics were recorded, and pH changes and turbidity were measured at time intervals. FINDINGS: Imipenem/cilastatin/relebactam was found to be compatible with a wide range of intravenous medications, facilitating co-administration with various IV medications. IMPLICATIONS: The compatibility reported is limited to a 2-h observation period in this study to adequately cover imipenem/cilastatin/relebactam infusion time. In addition, it is based on the measured turbidity with no chemical assay of the components of the admixture.

Incidence of pathogenic, likely pathogenic, and uncertain ALS variants in a clinic cohort.

OBJECTIVE: To determine the incidence of amyotrophic lateral sclerosis (ALS) genetic variants in a clinic-based population. METHODS: A prospective cohort of patients with definite or probable ALS was offered genetic testing using a testing algorithm based on family history and age at onset. RESULTS: The incidence of pathogenic (P) or likely pathogenic (LP) variants was 56.0% in familial ALS (fALS); 11.8% in patients with ALS with a family history of dementia, and 6.8% in sporadic ALS (p < 0.001). C9orf72 expansions accounted for the majority (79%) of P or LP variants in fALS cases. Variants of uncertain significance were identified in 20.0% of fALS cases overall and in 35.7% of C9orf72-negative cases. P or LP variants were detected in 18.5% of early-onset cases (onset age <50 years); the incidence of P or LP variants was not significantly different between family history types in this group. CONCLUSIONS: Our data suggest that the incidence of P and LP variants in genes other than C9orf72 is lower than expected in Midwestern fALS cases compared with research cohorts and highlights the challenge of variant interpretation in ALS. An accurate understanding of the incidence of pathogenic variants in clinic-based ALS populations is necessary to prioritize targets for therapeutic intervention and inform clinical trial design.

Implementation of a Renal Replacement Therapy Simulation to Strengthen Essential Pharmacist Skills.

Objective. To assess third-year pharmacy students' knowledge and application of renal pharmacotherapy using a renal replacement therapy (RRT) simulation. Methods. A simulation was developed that involved three stations related to RRT: peritoneal dialysis, continuous renal replacement therapy (CRRT), and hemodialysis. Stations involved demonstration of each modality, literature searches for drug information questions related to renal dosing with written recommendations, and utilization of an electronic medical record (EMR) to develop a verbal Situation, Background, Assessment, Recommendation (SBAR) for a patient with chronic kidney disease (CKD). Pre- and post-simulation assessments regarding therapeutic knowledge of RRT was used. Results. All 174 students completed the pre- and post-simulation assessments over the course of two years. Student performance indicated significant improvement in overall knowledge based on the assessments with significant overall differences in questions relating to indications for RRT, type of RRT indicated for hemodynamic instability, and agents used to maintain circuit patency. Overall inter-class differences were also identified at baseline and specifically for the questions regarding indications for RRT and agents used to maintain circuit patency. Both classes showed significant improvement in overall knowledge based on the post-simulation assessments. Debrief sessions and course evaluations indicated student satisfaction with the simulation experience. Students reported that the experience met the simulation objectives. Conclusion. Participation in an RRT simulation allowed pharmacy students to apply knowledge and skills learned didactically related to renal pharmacotherapy.

Impact of an interprofessional transition of care service on 30-day hospital reutilizations.

The objective of this study was to evaluate the impact of an interprofessional Transitions of Care (TOC) service on 30-day hospital reutilization inclusive of hospital readmissions and ED visits. This was a retrospective cohort study including patients discharged from an academic medical center between September 2013 and October 2014. Patients scheduled for a hospital follow-up visit in the post-acute care clinic (PACC) were included in the intervention group and patients without a post-discharge interprofessional TOC service were included in the comparison group. The intervention included a hospital follow-up visit with an interprofessional healthcare team. The primary composite outcome was hospital reutilization, defined as a hospital readmission or ED visit within 30 days of the discharge date. Overall, 330 patients were included in each group. In the intention-to-treat analysis, the primary composite outcome was not significantly different between groups (16.97% vs. 19.39%, P = 0.4195) whereas in the per-protocol analysis (all patients who showed to their PACC appointment), the primary outcome was significantly different in favor of the intervention group (9.28% vs. 19.39%, P = 0.0009). When components were analyzed separately, there was a statistically significant difference in favor of intervention group for hospital readmissions, but there was no difference for ED visits. This study demonstrates that an outpatient interprofessional TOC service with patient engagement from a team of nurses, pharmacists, physicians, and social workers may reduce 30-day hospital readmissions but may not impact 30-day ED visits.

A pilot IPE workshop integrating OT, pharmacy, PT, and PA programs.

BACKGROUND AND PURPOSE: This article describes the development, implementation, and evaluation of an interprofessional education (IPE) experience. EDUCATIONAL ACTIVITY AND SETTING: The IPE experience included 53 student learners from occupational therapy, pharmacy, physical therapy, and physician assistant programs at the University of the Sciences (USciences). This experience used an icebreaker activity and a stroke case-based activity as the activities within the workshop. The core faculty utilized the jigsaw technique to increase student confidence with uni-profession and interprofessional discussions of the patient case. Learners were asked to evaluate their perceptions of the IPE learning experience. FINDINGS: Results from a summative quality improvement evaluation indicated that learners had positive perceptions of this curricular innovation. DISCUSSION: This pilot IPE workshop illustrates the possibilities for collaboration among health professional programs at USciences, a private health sciences university without an affiliated medical center. SUMMARY: Discussion of the process to create, implement, and evaluate this pilot IPE activity is imperative due to increased expectations within professional accrediting guidelines in regards to IPE.

Enhancing Student Knowledge Through a Comprehensive Oncology Simulation.

Objective. To evaluate the impact of a comprehensive oncology simulation on pharmacy students' knowledge and perceptions related to oncology pharmacy practice. Methods. Third-year pharmacy students at the University of South Florida completed an ovarian cancer case-based simulation. Stations involved patient-specific order set completion, counseling, order verification, and aseptic technique. Pre- and post-simulation assessments regarding therapeutic knowledge and aseptic technique as well as perceptions of pharmacists' roles in oncology practice were evaluated. Results. All students (n=109, 100%) completed the pre- and post-simulation assessments. There was an increase in knowledge after the simulation, which was statistically significant in three of the six questions. Furthermore, students' perceptions regarding pharmacist roles and self-confidence in ability to prepare patient-specific regimens increased on a 5-point Likert scale from 3.8 and 3.2 to 4.5 and 4.2 on the post-assessment, respectively. Conclusion. Participation in the simulation improved students' oncology-related knowledge and perceived understanding of the roles of oncology pharmacists.

Using high-fidelity simulation to teach fundamental principles of cardiac catheterisation to pharmacy students.

Background: Pharmacy students often find the pathophysiology and treatment of comorbid heart conditions challenging to understand. The objective of this study is to evaluate the impact of a cardiac catheterisation lab simulation on pharmacy students' knowledge related to cardiology and critical care pharmacotherapy. Methods: Third-year pharmacy students at the University of South Florida completed a high-fidelity cardiac catheterisation simulation. Specific aspects within the activity involved review of clinical parameters and images during catheterisation, identification of access points for catheter insertion, review of the types of stents available and associated pharmacotherapeutic considerations, and discussion of protective measures to prevent radiation exposure. Students completed knowledge-based presimulation and postsimulation assessments regarding these aspects of cardiac catheterisation. Results: All students (n=111, 100%) completed the presimulation and postsimulation assessments. There was an increase in knowledge after the simulation, which was statistically significant in five out of nine questions, P<0.001. Based on course evaluations, students believed this activity enhanced their learning and ability to apply the material due to the close alignment and timing with their acute coronary syndrome lectures and the critical care module in the Pharmacotherapeutics course. Conclusions: Participation in the simulation improved students' knowledge related to cardiology pharmacotherapy and associated acute procedures.

Evaluation of pharmacy students' knowledge and perceptions of pharmacogenetics before and after a simulation activity.

BACKGROUND AND PURPOSE: The purpose of this study was to evaluate students' knowledge and perceptions of the clinical application of pharmacogenetics through a simulation activity and to assess communication of pharmacogenetic-guided treatment recommendations utilizing standardized patients. EDUCATIONAL ACTIVITY AND SETTING: Third-year students in the four-year doctor of pharmacy (PharmD) program at University of South Florida College of Pharmacy completed a pharmacogenetics simulation involving a patient case review, interpretation of pharmacogenetic test results, completion of a situation, background, assessment, recommendation (SBAR) note with drug therapy recommendations, and patient counseling. Voluntary assessments were completed before and after the simulation, which included demographics, knowledge, and perceptions of students' ability to interpret and communicate pharmacogenetic results. FINDINGS: Response rates for the pre- and post-simulation assessments were 109 (98%) and 104 (94%), respectively. Correct responses in application-type questions improved after the simulation (74%) compared to before the simulation (44%, p < 0.01). Responses to perception questions shifted towards "strongly agree" or "agree" after the simulation (p < 0.01). DISCUSSION AND SUMMARY: The simulation gave students an opportunity to apply pharmacogenetics knowledge and allowed them to gain an appreciation of pharmacists' roles within the pharmacogenetics field.

Rethinking transitions of care: An interprofessional transfer triage protocol in post-acute care.

Readmissions to hospitals from post-acute care (PAC) units within long-term care settings have been rapidly increasing over the past decade, and are drivers of increased healthcare costs. With an average of $11,000 per admission, there is a need for strategies to reduce 30-day preventable hospital readmission rates. In 2018, incentives and penalties will be instituted for long-term care facilities failing to meet all-cause, all-condition hospital readmission rate performance measures. An interprofessional team (IPT) developed and implemented a Transfer Triage Protocol used in conjunction with the INTERACT programme to enhance clinical decision-making and assess the potential to reduce the facility's 30-day preventable hospital readmission rates by 10% within 6 weeks of implementation. Results from quantitative analysis demonstrated an overall 35.2% reduction in the 30-day preventable hospital readmission rate. Qualitative analysis revealed the need for additional staff education, improved screening and communication upon admission and prior to hospital transfer, and the need for more IPT on-site availability. This pilot study demonstrates the benefits and implications for practice of an IPT to improve the quality of care within PAC and decrease 30-day preventable hospital readmissions.

Partners in Public Health: Public Health Collaborations With Schools of Pharmacy, 2015.

To collect data on public health collaborations with schools of pharmacy, we sent a short electronic survey to accredited and preaccredited pharmacy programs in 2015. We categorized public health collaborations as working or partnering with local and/or state public health departments, local and/or state public health organizations, academic schools or programs of public health, and other public health collaborations. Of 134 schools, 65 responded (49% response rate). Forty-six (71%) responding institutions indicated collaborations with local and/or state public health departments, 34 (52%) with schools or programs of public health, and 24 (37%) with local and/or state public health organizations. Common themes of collaborations included educational programs, community outreach, research, and teaching in areas such as tobacco control, emergency preparedness, chronic disease, drug abuse, immunizations, and medication therapy management. Interdisciplinary public health collaborations with schools of pharmacy provide additional resources for ensuring the health of communities and expose student pharmacists to opportunities to use their training and abilities to affect public health. Examples of these partnerships may stimulate additional ideas for possible collaborations between public health organizations and schools of pharmacy.

Vancomycin Dosing and Monitoring in the Treatment of Cystic Fibrosis: Results of a National Practice Survey.

OBJECTIVES: Vancomycin is commonly used in patients with cystic fibrosis (CF) to treat acute pulmonary exacerbations, but few guidelines exist to help dose and monitor patients. The objective of this study was to assess vancomycin use and monitoring strategies at Cystic Fibrosis Foundation (CFF)-accredited centers in hopes of developing and implementing vancomycin dosing and monitoring standards. METHODS: An anonymous national cross-sectional survey of pharmacists affiliated with CFF-accredited pediatric and/or adult centers was performed by using Surveymonkey.com. The survey consisted of 3 sections: (1) CF Center Demographic Information (10 questions); 2) vancomycin use in pediatric CF patients (31 questions); and 3) vancomycin use in adult CF patients (29 questions); it was administered from March 9, 2015, to April 13, 2015. RESULTS: The survey was completed by 31/69 (45%) pharmacists and 28 (90.3%) reported using vancomycin in the pediatric population. The most common initial starting dose for pediatric patients was 15 mg/kg/dose (57.1%) and every 6 hours was the most common dosing frequency (67.9%). The most common monitoring strategy was collection of a trough concentration (92.9%) with 57.7% of pharmacist targeting a range of 15 to 20 mg/L. The most common initial starting vancomycin dose in adults with CF was 15 mg/kg/dose (61.5%), and initial frequency of every 8 hours (73.1%). The most common monitoring strategy was a trough concentration (96.2%) with 83.3% of pharmacists reporting a goal trough range of 15 to 20 mg/L. CONCLUSIONS: The most common vancomycin dosing reported was 15 to 20 mg/kg/dose every 6 hours (pediatric) and 15 to 20 mg/kg/dose every 8 to 12 hours (adults). Serum concentrations measured to meet monitoring parameters of trough concentrations of 15 to 20 mg/L, or area under the curve to minimum inhibitory concentration ratio > 400, were the same in both pediatric and adult patients.

EPA-Registered Repellents for Mosquitoes Transmitting Emerging Viral Disease.

In many parts of the United States, mosquitoes were previously nuisance pests. However, they now represent a potential threat in the spread of viral diseases. The Aedes aegypti, Aedes albopictus, and Culex species mosquitoes are endemic to the United States and together may transmit a variety of viral diseases of growing concern, including West Nile virus, chikungunya, dengue fever, and Zika virus. The Centers for Disease Control and Prevention and the Environmental Protection Agency (EPA) recommend N,N-diethyl-meta-toluamide (DEET) as a first-line mosquito repellent, but for patients refusing to use DEET or other conventional repellents, guidance is limited to any EPA-registered product. Therefore, we conducted a systematic review of the literature to identify which EPA-registered personal mosquito repellent provides the best protection from A. aegypti, A. albopictus, and Culex spp. mosquitoes. We abstracted data from 62 published reports of EPA-registered mosquito repellents. The conventional repellent picaridin has the strongest data to support its use as a second-line agent, while IR3535 and oil of lemon eucalyptus are reasonably effective natural products. Citronella, catnip, and 2-undecanone offer limited protection or have limited data. These results can be used by pharmacists and other health care professionals to advise patients on the selection of an EPA-registered mosquito repellent. Regardless of the repellent chosen, it is vital for patients to follow all instructions/precautions in the product labeling to ensure safe and effective use.
