RESUMO
Biodiversity conservation has been a critical challenge faced by environmental managers worldwide. From 2020 to 2022, a total of 576 underwater visual censuses focused on reef fishes, marine litter (ML), and non-native species were performed in the newest Brazilian Hope Spot, to understand the distribution, characteristics, and effects of ML and Tubastraea spp., on the reef fish community. Plastic was the main category recorded (34.54 %), followed by Metal and Line (mostly fishing gear within a Marine Protected Area). Tubastraea spp. was widely distributed, especially between 10-20 meters deep. The t-test analysis showed that fish abundance and richness were significantly higher at low Tubastraea cover areas. Our efforts present the baseline of ML (mean 1.92 ± 1.5 items/100 m2) and non-native species occurrence (15) and distribution (including three new records) showing their negative impacts on rocky reef ecosystems and provide managers support in the elaboration of marine conservation strategies.

The role of clinical pathologists or laboratory-based physicians is being challenged on several fronts-exponential advances in technology, increasing patient autonomy exercised in the right to directly request tests and the use of non-medical specialists as substitutes. In response, clinical pathologists have focused their energies on the pre-analytical and postanalytical phases of Laboratory Medicine thus emphasising their essential role in individualised medical interpretation of complex laboratory results. Across the European Union, the role of medical doctors is enshrined in the Medical Act. This paper highlights the relevance of this act to patient welfare and the need to strengthen training programmes to prevent an erosion in the quality of Laboratory Medicine provided to patients and their physicians.

Os autores descrevem uma opçäo de tratamento em casos de escurecimento dentais severos, através do uso de facetas laminadas de porcelana. Apresentam um caso clínico com a sequência dos principais passos realizados, com consideraçöes teóricas e práticas, em um paciente com manchas severas por tetraciclina. Ressaltam, também, as vantagens e desvantagens da técnica, os critérios para a realizaçäo do laminado cerâmico, bem como, a importância da adequada seleçäo do paciente para que o melhor resultado fosse alcançado com as facetas de porcelana
