Diagnosing and treating pericarditis and myocarditis in the emergency department.

Pericarditis and myocarditis represent a challenging set of diseases to diagnose and treat. These diseases typically present with chest pain and dyspnea in previously healthy young people, often in the weeks following a viral illness, including COVID-19. Nonetheless, the etiologies can be very diverse, including infectious, noninfectious, drug-induced, and autoimmune causes.

Performance comparison of intraosseous devices and setups for infusion of whole blood in a cadaveric swine bone model.

Objectives: Intraosseous (IO) access can provide a critical bridge for blood product infusion when peripheral venous access is not obtainable. Successful pressurized IO infusion requires flow rates sufficient to preserve life, but with infusion pressures low enough to avoid clinical complications (e.g.

Histopathological Findings in Cynomolgus Macaques ( Macaca fascicularis) Consistent with Secondary Immunological Reaction to Biotherapeutics with an Emphasis on the CNS and Eye.

Biotherapeutics are pharmaceutical products derived from or synthesized by biological systems. Such molecules carry the potential for immunogenicity which may lead to adverse immune responses. The cynomolgus macaque ( Macaca fascicularis) is the species of choice in nonclinical safety assessment of biotherapeutics.

Evaluation of the PhysioTel™ Digital M11 cardiovascular telemetry implant in socially housed cynomolgus monkeys up to 16weeks after surgery.

Introduction: The novel PhysioTel™ Digital M11 telemetry implant was evaluated in socially housed monkeys with respect to both safety pharmacological cardiovascular (arterial blood pressure (BP), heart rate (HR) and electrocardiogram (ECG)) and toxicological (clinical pathology and histopathology) endpoints.

Methods: Telemetry and clinical pathology data were obtained repeatedly up to 16weeks after surgery in four female cynomolgus monkeys, followed by necropsy. Due to postsurgical complications, one spare animal was included and only toxicological endpoints from the affected (fifth animal) were reported.

Vehicle Systems and Excipients Used in Minipig Drug Development Studies.

Minipigs have been used for dermal drug development studies for decades, and they are currently more frequently considered as the second nonrodent species for pivotal nonclinical studies, in lieu of the dog or nonhuman primate, for compounds delivered via standard systemic routes of administration. Little is known about the tolerability of different excipients in minipigs; sharing knowledge of excipient tolerability and compositions previously used in nonclinical studies may avoid testing of inadequate formulations, thereby contributing to reduced animal usage. This article reviews vehicles employed in the Göttingen(®)minipig based on the combined experience from a number of pharmaceutical companies and contract research organizations.

The minipig as nonrodent species in toxicology--where are we now?

Over the past 3 decades minipigs have moved from being an obscure alternative to dogs and nonhuman primates to being a standard animal model in regulatory toxicity studies. This article covers the use of minipigs as a model in the context of nonclinical drug safety and provides an overview of the minipig's developmental history and relates minipigs to other animal species commonly used in toxicology; and the minipig's translational power is supported by 43 case studies of marketed drug products covered. Special focus is given to criteria for selecting minipigs in nonclinical programs supporting the development of new medicines; the use of swine in the assessment of food additives, agrochemicals, and pesticides; as well as a regulatory perspective on the use of minipigs in Food and Drug Administration (FDA)-regulated products.
