Continuity of care for patients recovering from Covid-19 under the angle of clinical management principles.

Objective: To analyze the strategies used by nurses at a university hospital to ensure continuity of care at hospital discharge for patients recovered from Covid-19, under the angle of the principles of clinical management.

Method: A descriptive study with a qualitative approach, carried out with seven nurses on duty in the medical and gynecology/obstetrics clinics of a university hospital in the Midwest region of the country. The data was processed using IRaMuTeQ software and analyzed using Content Analysis.

Diversity of Phospholipases A from Snake Venom: Adaptive Advantages for Snakes Compromising Treatments for Snakebite Patients.

The evolution of snake venoms resulted in multigene toxin families that code for structurally similar isoforms eventually harboring distinct functions. PLAs are dominant toxins in viper venoms, and little is known about the impact of their diversity on human envenomings and neutralization by antivenoms. Here, we show the isolation of three distinct PLAs from venom.

Prevalence and factors associated with mercury exposure in riverside communities in the Brazilian Western Amazon.

Objective: to verify mercury exposure prevalence and identify its possible associated factors in two riverside communities in the Madeira River basin of the Western Brazilian Amazon.

Method: a cross-sectional study comprising 95 children and adolescents. Age cycle, school attendance, Bolsa Família, number of siblings, meals, fish consumption, height by age were measured.

The cutaneous secretion of the casque-headed tree frog Corythomantis greeningi: Biochemical characterization and some biological effects.

Corythomantis greeningi is a tree-frog endemic of the Brazilian semi-arid (Caatinga), mainly characterized by the flat, mineralized and spiny head, which is associated with phragmotic habits. It is already known that the skin secretion of this amphibian from both head and body is quite toxic and is used as an efficient chemical defence against predators. However, the biochemical characteristics and pharmacological effects of this secretion are still very little studied.

Venomous Frogs Use Heads as Weapons.

Venomous animals have toxins associated with delivery mechanisms that can introduce the toxins into another animal. Although most amphibian species produce or sequester noxious or toxic secretions in the granular glands of the skin to use as antipredator mechanisms, amphibians have been considered poisonous rather than venomous because delivery mechanisms are absent. The skin secretions of two Brazilian hylid frogs (Corythomantis greening and Aparasphenodon brunoi) are more toxic than the venoms of deadly venomous Brazilian pitvipers, genus Bothrops; C.
