Pharmacokinetic, sedative, and physiological effects of oral compounded formulations of trazodone alone or in combination with gabapentin in male cats.

Trazodone and gabapentin are common oral sedatives in cats, used alone or combined, but no pharmacokinetic studies exist for trazodone in this species. The objective of this study was to determine the pharmacokinetics of oral trazodone (T) alone, or in combination with gabapentin (G) in healthy cats. Cats (n = 6) were randomly allocated to receive T (3 mg/kg) intravenously (IV), T (5 mg/kg) orally (PO), or T (5 mg/kg) and G (10 mg/kg) PO with a 1-week washout period between treatments. Heart rate, respiratory rate, indirect blood pressure, and level of sedation were assessed, and venous blood samples were collected serially over 24 h. Analysis of plasma trazodone concentration was performed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Oral T administration resulted in a bioavailability of 54.9(7-96)%, and 17.2(11-25)% when administered with G. Tmax 0.17 (0.17-0.5) and 0.17 (0.17-0.75) h; Cmax 1.67 ± 0.91 and 1.22 ± 0.54 µg/mL, AUC 5.23 (2.0-18.76) and 2.37 (1.17-7.80) h*µg/mL; T1/2 5.12 ± 2.56 and 4.71 ± 1.07 h; for T and TG, respectively. Sedation was significant when compared to baseline in all groups from 20 or 45 min to 8 h indicating some lag between peak plasma concentration and sedative effects. Physiological variables remained within normal limits. This study concludes that oral trazodone is rapidly absorbed in healthy cats. Addition of gabapentin did not result in more profound sedation, showing no clinical advantage of combining these drugs in this study population.

A Smart Textile Band Achieves High-Quality Electrocardiograms in Unrestrained Horses.

Electrocardiography (ECG) is an essential tool in assessing equine health and fitness. However, standard ECG devices are expensive and rely on the use of adhesive electrodes, which may become detached and are associated with reduced ECG quality over time. Smart textile electrodes composed of stainless-steel fibers have previously been shown to be a suitable alternative in horses at rest and during exercise. The objective of this study was to compare ECG quality using a smart textile girth band knit with silver and carbon yarns to standard adhesive silver/silver chloride (Ag/AgCl) electrodes. Simultaneous three-lead ECGs were recorded using a smart textile band and Ag/AgCl electrodes in 22 healthy, mixed-breed horses that were unrestrained in stalls. ECGs were compared using the following quality metrics: Kurtosis (k) value, Kurtosis signal quality index (kSQI), percentage of motion artifacts (%MA), peak signal amplitude, and heart rate (HR). Two-way ANOVA with Tukey's multiple comparison tests was conducted to compare each metric. No significant differences were found in any of the assessed metrics between the smart textile band and Ag/AgCl electrodes, with the exception of peak amplitude. Kurtosis and kSQI values were excellent for both methods (textile mean k = 21.8 ± 6.1, median kSQI = 0.98 [0.92−1.0]; Ag/AgCl k = 21.2 ± 7.6, kSQI = 0.99 [0.97−1.0]) with <0.5% (<1 min) of the recording being corrupted by MAs for both. This study demonstrates that smart textiles are a practical and reliable alternative to the standard electrodes typically used in ECG monitoring of horses.

Description and validation of a new descriptive and multiparametric numeric rating scale to assess sedation in cats.

The objective of this study was to design and assess the validity and reliability of a new feline multiparametric sedation scale (FMSS). A total of 89 household cats were recruited, enabling a total of 534 sedation assessments. Every assessment was performed by 3 blinded observers with varying expertise levels (Level 1: Student; Level 2: RVT; Level 3: ACVAA diplomate or senior resident). For comparison purposes, a visual analogue scale (VAS) and a Simple Qualitative Scale (SQS) were also used concurrently, with the VAS considered the gold standard. The new scale had excellent inter-observer agreement among experience groups with weighted Kappa scores of 0.84 (Levels 1 versus 2), 0.82 (Levels 2 versus 3), and 0.84 (Levels 1 versus 3), with P < 0.0001 for all comparisons. There was a high degree of association between FMSS and VAS (r = 0.90, P < 0.0001) and between FMSS and SQS (r = 0.89, P < 0.0001). Final FMSS numerical values were paired with levels of sedation with None = 0 (0 to 5), Mild = 4 (1 to 7), Moderate = 6 (2 to 10), and Profound = 12 (7 to 12); furthermore, differences were detected between pre- and post-sedation evaluations (P = 0.001). This scale demonstrated internal consistency and sensitivity even when evaluating drugs or doses with minimal sedative effects and there was very strong interrater reliability, independent of experience level. Based on this clinical study, we concluded that the use of this sedation scale is appropriate when objective numerical sedation quantification is required, in either a clinical or research setting.

Description et validation d'une nouvelle échelle d'évaluation numérique descriptive et multiparamétrique pour évaluer la sédation chez le chat. L'objectif de cette étude était de concevoir et d'évaluer la validité et la fiabilité d'une nouvelle échelle de sédation multiparamétrique féline (FMSS). Un total de 89 chats domestiques a été recruté, permettant un total de 534 évaluations de sédation. Chaque évaluation a été effectuée par trois observateurs en aveugle avec différents niveaux d'expertise (Niveau 1 : étudiant; Niveau 2 : RVT; Niveau 3 : diplomate de l'ACVAA ou résident senior). À des fins de comparaison, une échelle visuelle analogique (VAS) et une échelle qualitative simple (SQS) ont également été utilisées simultanément, VAS étant considérée comme l'étalon. La nouvelle échelle présentait un excellent accord inter-observateurs parmi les groupes d'expérience avec des scores Kappa pondérés de 0,84 (niveaux 1 versus 2), 0,82 (niveaux 2 versus 3) et 0,84 (niveaux 1 versus 3), avec P < 0,0001 pour toutes les comparaisons. Il y avait un degré élevé d'association entre FMSS et VAS (r = 0,90, P < 0,0001) et entre FMSS et SQS (r = 0,89, P < 0,0001). Les valeurs numériques FMSS finales ont été appariées avec les niveaux de sédation avec Aucun = 0 (0 à 5), Léger = 4 (1 à 7), Modéré = 6 (2 à 10) et Profond = 12 (7 à 12); en outre, des différences ont été détectées entre les évaluations pré- et post-sédation (P = 0,001). Cette échelle a démontré une cohérence interne et une sensibilité même lors de l'évaluation de médicaments ou de doses avec des effets sédatifs minimes et il y avait une très forte fiabilité inter-évaluateur, indépendamment du niveau d'expérience. Sur la base de cette étude clinique, nous avons conclu que l'utilisation de cette échelle de sédation est appropriée lorsqu'une quantification numérique objective de la sédation est requise, dans un cadre clinique ou de recherche.(Traduit par Dr Serge Messier).

Cancer Incidence and Mortality Among Fighter Aviators in the United States Air Force.

OBJECTIVE: This study sought to clarify cancer risk in fighter aviators. METHODS: US Air Force officers who served between 1970 and 2004 were followed through 2018 for incidence and mortality of 10 cancers: colon and rectum; pancreas; melanoma skin; prostate; testis; urinary bladder; kidney and renal pelvis; brain and other nervous system; thyroid; and non-Hodgkin lymphoma. Fighter aviators were compared with other officers and the general US population. RESULTS: Compared with other officers, male fighter aviators had greater adjusted odds of developing testis, melanoma skin, and prostate cancers; mortality odds were similar for all cancers. When compared with the US population, male fighter aviators were more likely to develop and die from melanoma skin cancer, prostate cancer, and non-Hodgkin lymphoma. CONCLUSIONS: Military fighter aviation may be associated with slightly increased risk of certain cancers.

Malaria Prophylaxis Adherence Among Aircrew Members.

INTRODUCTION: Joint Base Charleston's C-17 Globemaster III mission is executed by 400 active-duty members from three operational and support wings. Aircrew and mission-essential personnel travel to locations with endemic diseases which are mostly eradicated in the United States. Recently, two members contracted malaria after missions in Africa which required advanced hospital care. Personnel were provided chemoprophylaxis, but the members who contracted malaria were among several who chose not to take it. This preliminary survey assessed aircrew malaria prophylaxis adherence and examined potential factors contributing to nonadherence.METHODS: JB Charleston aircrew members who visited the Flight and Operational Medicine Clinic between January and April 2018 were administered a retrospective, online survey. Researchers performed descriptive statistics and Chi-squared analysis.RESULTS: Most respondents were pilots under 30 yr of age and were prescribed malaria chemoprophylaxis while on a mission. More than two-thirds of respondent aircrew members did not take the medication as prescribed or did not take it at all. Of those, over half of respondents stated too many pills/too many days and medication side effects as the main reasons for nonadherence. Furthermore, almost 70% of adherent members experienced negative medication side effects such as nausea and heightened dreams. There was no statistical relationship between crew position, age, side effects, and prophylaxis adherence.DISCUSSION: Numerous factors contribute to poor prophylaxis regimen compliance among aircrew members. This study highlighted the need for risk-based policy validation, improved patient education, prophylaxis enforcement, process improvements to facilitate adherence, and evaluation of perceived vs. actual risk.Rutherford AE, Yale RS, Finn MF.

Benefits of Less Restrictive Regulation of Advance Practice Registered Nurses in Florida.

BACKGROUND: Advanced Practice Registered Nurses (APRNs) provide access to cost-effective, high quality care. APRNs are underutilized in states that restrict their practice. Removing restrictions could expand access to quality health care, cost-effectively relieve the physician shortage, and contribute economically. PURPOSE: This study forecasts the health system and economic impacts of reducing practice restrictions for Florida APRNs. METHODS: The analysis utilized a number of data sources and IMPLAN software and estimated changes in APRN supply given less restrictive practice laws, and consequential health system and economic benefits. FINDINGS: Between 2013 and 2025 APRN full time equivalents could increase an additional 11% with less restrictive practice regulations. This could eliminate or reduce the shortage of different types of physicians. Health care cost-savings could be $50 to $493 per resident. There would be a number of general economic benefits. DISCUSSION: A number of health system and economic benefits would ensue from less restrictive APRN regulation.

Data breach locations, types, and associated characteristics among US hospitals.

OBJECTIVES: The objectives of this study were to describe the locations in hospitals where data are breached, the types of breaches that occur most often at hospitals, and hospital characteristics, including health information technology (IT) sophistication and biometric security capabilities, that may be predicting factors of large data breaches that affect 500 or more patients. STUDY DESIGN: The Office of Civil Rights breach data from healthcare providers regarding breaches that affected 500 or more individuals from 2009 to 2016 were linked with hospital characteristics from the Health Information Management Systems Society and the American Hospital Association Health IT Supplement databases. METHODS: Descriptive statistics were used to characterize hospitals with and without breaches, data breach type, and location/mode of data breaches in hospitals. Multivariate logistic regression analysis explored hospital characteristics that were predicting factors of a data breach affecting at least 500 patients, including area characteristics, region, health system membership, size, type, biometric security use, health IT sophistication, and ownership. RESULTS: Of all types of healthcare providers, hospitals accounted for approximately one-third of all data breaches and hospital breaches affected the largest number of individuals. Paper and films were the most frequent location of breached data, occurring in 65 hospitals during the study period, whereas network servers were the least common location but their breaches affected the most patients overall. Adjusted multivariate results showed significant associations among data breach occurrences and some hospital characteristics, including type and size, but not others, including health IT sophistication or biometric use for security. CONCLUSIONS: Hospitals should conduct routine audits to allow them to see their vulnerabilities before a breach occurs. Additionally, information security systems should be implemented concurrently with health information technologies. Improving access control and prioritizing patient privacy will be important steps in minimizing future breaches.

Impact of Health Literacy on Senior Citizen Engagement in Health Care IT Usage.

Objective: Patient engagement in health care information technology (IT) is required for government reimbursement programs. This research surveyed one older adult group to determine their willingness to use health information from a variety of sources. Health literacy was also measured using the Newest Vital Sign (NVS) and eHealth Literacy Scale (eHEALS) tools. Method: Regression models determined engagement in health care IT usage and impact of literacy levels based on survey data collected from the group. Results: Although most participants have adequate literacy, they are not more likely to use health care IT than those with limited literacy scores. Knowledge of how to use the Internet to answer questions about health was statistically associated with IT usage. Discussion: Health care IT usage is important for healthy aging. The ability of older adults to understand information provided to them can impact population health including medication usage and other important factors.
