Revisiting Ophidiomycosis (Snake Fungal Disease) After a Decade of Targeted Research.

Emerging infectious diseases (EIDs) are typically characterized by novelty (recent detection) and by increasing incidence, distribution, and/or pathogenicity. Ophidiomycosis, also called snake fungal disease, is caused by the fungus (formerly "). Ophidiomycosis has been characterized as an EID and as a potential threat to populations of Nearctic snakes, sparking over a decade of targeted research.

Electronically monitored dosing histories can be used to develop a medication-taking habit and manage patient adherence.

Nonadherence to prescribed medications can lead to medical complications, disease progression, hospitalizations, overestimated dosing requirements, impaired quality of life, and death, as well as incurring substantive costs for the healthcare system from suboptimal dosing during ambulatory pharmacotherapy. Adherence can be improved by helping patients build habits of taking prescribed medications, impacting day-to-day implementation of and persistence with rationally prescribed drug dosing regimens. Accurate, easily understood and personally relevant feedback is clearly relevant to many patients in this process.

Identification and assessment of adherence-enhancing interventions in studies assessing medication adherence through electronically compiled drug dosing histories: a systematic literature review and meta-analysis.

Background: Non-adherence to medications is prevalent across all medical conditions that include ambulatory pharmacotherapy and is thus a major barrier to achieving the benefits of otherwise effective medicines.

Objective: The objective of this systematic review was to identify and to compare the efficacy of strategies and components thereof that improve implementation of the prescribed drug dosing regimen and maintain long-term persistence, based on quantitative evaluation of effect sizes across the aggregated trials.

Data Sources: MEDLINE, EMBASE, CINAHL, the Cochrane Library, and PsycINFO were systematically searched for randomized controlled trials that tested the efficacy of adherence-enhancing strategies with self-administered medications.

Young adult preventive health care guidelines: there but can't be found.

Objectives: To (1) identify adolescent and adult clinical preventive services guidelines relevant to the young adult age group; (2) review, compare, and synthesize these guidelines, with emphasis on the extent to which professional guidelines are consistent with evidence-based guidelines developed by the US Preventive Services Task Force; and (3) recommend the next steps in the establishment and integration of preventive care guidelines for young adults.

Design: Nonexperimental: an Internet search was conducted to identify relevant preventive care guidelines for the young adult group.

Setting: The search included federal agencies and professional organizations that focus on health areas linked to the care of young adults or that provide health care to adolescents and young adults.

Adherence to medications: insights arising from studies on the unreliable link between prescribed and actual drug dosing histories.

Satisfactory adherence to aptly prescribed medications is essential for good outcomes of patient care and reliable evaluation of competing modes of drug treatment. The measure of satisfactory adherence is a dosing history that includes timely initiation of dosing plus punctual and persistent execution of the dosing regimen throughout the specified duration of treatment. Standardized terminology for initiation, execution, and persistence of drug dosing is essential for clarity of communication and scientific progress.

[Compliance, concordance, adherence].

Ambulatory pharmacotherapy is marked by many deviations, mostly downward, in drug dosing from prescribed instructions. Soundly compiled dosing histories date from 1977, based on electronic time-stamping of medication 'events': package entry times, done first with eyedrop dispensers for glaucoma drugs. Electronically monitored packages for oral dosage forms date from 1988.

Living history: F. Eugene Yates.

In 2005, the American Physiological Society (APS) initiated the Living History of Physiology Archival Program to recognize senior members who have made significant contributions during their career to the advancement of the discipline and the profession of physiology. During 2008, the APS Cardiovascular Section selected Francis Eugene Yates to be profiled in Advances in Physiology Education.

Historical vicariance and male-mediated gene flow in the toad-headed lizards Phrynocephalus przewalskii.

Using mitochondrial and microsatellite DNA data and a population genetic approach, we tested male-mediated gene flow in the toad-headed lizards Phrynocephalus przewalskii. The mitochondrial DNA (ND2 gene), on the one hand, revealed two major lineages and a strong population genetic structure (F(ST) = 0.692; F(ST)' = 0.

Adherence to prescribed antihypertensive drug treatments: longitudinal study of electronically compiled dosing histories.

Objective: To describe characteristics of dosing history in patients prescribed a once a day antihypertensive medication.

Design: Longitudinal database study.

Setting: Clinical studies archived in database for 1989-2006.

Estimation of the comparative therapeutic superiority of QD and BID dosing regimens, based on integrated analysis of dosing history data and pharmacokinetics.

Once-daily dosing almost invariably shows a slightly higher percentage of prescribed doses taken than does twice-daily dosing. Many pharmaceutical scientists, regulators, and prescribers have considered this finding to signify the therapeutic superiority of once-daily dosing. The therapeutically more relevant question, however, is not the percentage of prescribed doses taken but the comparative impact of missed doses on the pharmacologic effects of a drug under the two dosing regimens.

Modelling the association between adherence and viral load in HIV-infected patients.

The primary objective of this paper is to investigate the effect of adherence to prescribed antiretroviral therapy on virologic response measured repeatedly over time in HIV-infected patients. To this end observations on plasma viral load (HIV RNA) assessed in copies/ml are categorized into four clinically meaningful states, [0--50[, [50--400[, [400--2000[, [2000 and up. A time-dependent continuation ratio model is used to analyse longitudinal ordinal responses.

Successful projection of the time course of drug concentration in plasma during a 1-year period from electronically compiled dosing-time data used as input to individually parameterized pharmacokinetic models.

Pharmacokinetic studies rely on blood sampling at times relative to predefined dosing intervals. Intensive sampling is often done under direct observation of dose taking, which, though costly, virtually eliminates uncertainty about actual dosing times. In contrast, the sparse sampling done in population pharmacokinetic studies relies on patient-reported times of dosing, the accuracy of which the authors sought to assess by adding electronic monitoring to the usual patient reporting of dosing times.

Patient adherence to prescribed antimicrobial drug dosing regimens.

The aim of this article is to review current knowledge about the clinical impact of patients' variable adherence to prescribed anti-infective drug dosing regimens, with the aim of renewing interest and exploration of this important but largely neglected area of therapeutics. Central to the estimation of a patient's adherence to a prescribed drug regimen is a reliably compiled drug dosing history. Electronic monitoring methods have emerged as the virtual 'gold standard' for compiling drug dosing histories in ambulatory patients.

The odds that clinically unrecognized poor or partial adherence confuses population pharmacokinetic/pharmacodynamic analyses.

Electronic compilation of ambulatory patients' or trial participants' dosing histories has revealed that a wide range of dosing patterns, markedly skewed toward underdosing, occur in virtually every disease and treatment situation so far studied. In planning ambulatory trials and their analyses, one should recognize that patients' variable exposure to test drugs, created by their diversely erratic execution of protocol-specified dosing regimens, is generally the single largest source of variance in drug responses. Trial subjects' erratic dosing behaviour may, if ignored, weaken the trial's assay sensitivity.

Effect of a pharmacist-led intervention on diuretic compliance in heart failure patients: a randomized controlled study.

Background: Noncompliance is a major factor in the morbidity and unnecessary hospital readmissions for patients with heart failure. Several studies have aimed to reduce rehospitalizations in heart failure patients through a comprehensive, multidisciplinary approach. Medication compliance was rarely measured in these studies or, when it was measured, the method employed was seldom valid.

Patient compliance in rheumatoid arthritis, polymyalgia rheumatica, and gout.

Objective: (1) To explore patient compliance with prescribed drug regimens in the setting of usual care for outpatients with rheumatoid arthritis (RA), gout, and polymyalgia rheumatica (PMR) by utilizing electronic medication event monitors (MEMS(R)) to register openings of the medication package. (2) To examine the influence of disease, frequency of intake of the drug, and class of drug on compliance. (3) To explore the influence of demographic factors, quality of life measures, coping, health status, and functional ability as potential predictors of patient compliance.
