Locomotor play behavior evolves by random genetic drift but not as a correlated response to selective breeding for high voluntary wheel-running behavior.

Locomotor play is vigorous and seemingly purposeless behavior, commonly observed in young mammals. It can be costly in terms of energy expenditure, increased injury risk, and predator exposure. The main hypothesized benefit of locomotor play is enhancement of neuromuscular development, with effects persisting into adulthood.

Severe acute liver injury associated with .

is a Gram-negative bacterium that causes foodborne illnesses, typically characterised by acute febrile gastroenteritis and is associated with a variety of manifestations. Isolated febrile illness without gastrointestinal symptoms is rare. We report a case of   infection with severe anicteric hepatitis.

Use of complementary therapies for chronic pain management in patients with reported Ehlers-Danlos syndrome or hypermobility spectrum disorders.

Ehlers-Danlos Syndromes (EDS) and related Hypermobility Spectrum Disorders (HSD) are debilitating connective tissue disorders that feature a prominent pain component for which there are limited therapeutic options for pain management. Consequently, many patients try various non-prescribed treatments, including complementary and alternative therapies that have not been well studied in the EDS/HSD patient population. We surveyed over 500 individuals through the EDS Society who reported having been diagnosed with EDS or HSD to ascertain what complementary and alternative therapies were used and their reported effectiveness in alleviating pain and improving quality of life.
