The diagnosis and vector potential of Ornithonyssus bacoti tropical rat mites in northern Europe.

The mesostigmatid tropical rat mite, Ornithonyssus bacoti, is an important cause of disease in small rodents, and of gamasoidosis in humans when they come into contact with infestations. Most reports of O. bacoti infestations are from warmer parts of the Americas, southern Europe and Asia; and infection has only rarely been recorded in northern Europe.

Relationship between Systolic Ejection Time and Inflammation in End-Stage Heart Failure.

Objectives: Systolic ejection time (SET) and systemic inflammation are two essential indicators of heart failure (HF) progression. We aimed to evaluate the associations between SET and inflammatory mediators in end-stage HF.

Methods: Participants included 16 patients with end-stage HF recruited from the Heart Failure Clinic at Toronto General Hospital and 16 healthy individuals free of any known cardiovascular disease.

A description and outcome evaluation of sacrococcygeal joint radiofrequency neurotomy for treatment of chronic coccydynia - A dorsal approach.

Background: Coccydynia is a condition characterized by pain and tenderness in the coccyx region of the spine. Chronic coccydynia (≥3-months) management remains a clinical challenge. Radiofrequency neurotomy (RFN) targeting the sacrococcygeal joint (SCJ) and/or 1st intercoccygeal joint (ICJ) margins has emerged as an alternative, minimally invasive intervention for refractory coccydynia.

Prospective longitudinal investigation shows correlation of event-related potential to mild traumatic brain injury in adolescents.

Study Design: Prospective longitudinal cohort study.

Background: Adolescent athletes may be more susceptible to the long-term effects of mild traumatic brain injury (mTBI). A diagnostic and prognostic neuromarker may optimize management and return-to-activity decision-making in athletes who experience mTBI.
