Environmental enrichment for neotropical primates in captivity Enriquecimento ambiental para primatas neotropicais em cativeiro

Captivity is an extreme non-natural environment for primates. The success of a breeding colony depends of management and veterinarian procedures which must rely on the knowledge of primates' behavioral needs. Environmental enrichment consists of a series of procedures that improve the quality of life of captive animals by meeting their ethological needs. Enrichment can reduce stress, while increasing animal well being in captivity. Suitable ethical conditions, incidences of behavioral disorders, minimal clinical interventions, low mortality, higher reproduction rates and cost/benefit relationship, reflect directly on the quality of captive breeding colonies. Anthropoids like Neotropical primates possess complex neural structures and relate, in a sophisticated manner, to the environment. This review reports important experiences on enrichment procedures for Neotropical primates and the physiological events which could explain improvement of animal well-being.<br>Cativeiro é um ambiente de extremos não naturais para primatas. O sucesso de uma criação de primatas depende do manejo e de procedimentos veterinários que devem considerar as necessidades etológicas dos animais cativos. Enriquecimento ambiental é um conjunto de técnicas que modificam o ambiente, resultando em uma melhora na qualidade de vida dos animais, ao satisfazer as suas necessidades comportamentais. O enriquecimento pode diminuir o estresse e melhorar o bem-estar. Primatas neotropicais se caracterizam por complexas estruturas neurais e se relacionam de maneira sofisticada com o ambiente. O enriquecimento ambiental pode aumentar a qualidade de uma criação ao adequar o manejo a padrões éticos aceitáveis, estimular o repertório normal do comportamento, diminuir a casuística clínica, diminuir a mortalidade, incrementar a taxa reprodutiva e maximizar a relação custo/benefício em uma criação. Esta revisão relata experiências relevantes nos procedimentos de enriquecimento para primatas neotropicais, além de comentar as bases fisiológicas em que essas intervenções melhoram o bem-estar dos animais cativos

2021 DORIS definition of remission in SLE: Final recommendations from an international task force

Objective To achieve consensus on a definition of remission in SLE (DORIS). Background Remission is the stated goal for both patient and caregiver, but consensus on a definition of remission has been lacking. Previously, an international task force consisting of patient representatives and medical specialists published a framework for such a definition, without reaching a final recommendation. Methods Several systematic literature reviews were performed and specific research questions examined in suitably chosen data sets. The findings were discussed, reformulated as recommendations and voted on. Results Based on data from the literature and several SLE-specific data sets, a set of recommendations was endorsed. Ultimately, the DORIS Task Force recommended a single definition of remission in SLE, based on clinical systemic lupus erythematosus disease activitiy index (SLEDAI)=0, Evaluator’s Global Assessment &lt;0.5 (0–3), prednisolone 5 mg/day or less, and stable antimalarials, immunosuppressives, and biologics. Conclusion The 2021 DORIS definition of remission in SLE is recommended for use in clinical care, education, and research including clinical trials and observational studies. © 2021 BMJ Publishing Group.
