Autocrine glutamate signaling drives cell competition in Drosophila.

Cell competition is an evolutionarily conserved quality control process that eliminates suboptimal or potentially dangerous cells. Although differential metabolic states act as direct drivers of competition, how these are measured across tissues is not understood. Here, we demonstrate that vesicular glutamate transporter (VGlut) and autocrine glutamate signaling are required for cell competition and Myc-driven super-competition in the Drosophila epithelia.

Gender-specific counselling of patients with upper tract urothelial carcinoma and Lynch syndrome.

Purpose: Lynch syndrome (LS) is an autosomal dominant genetic syndrome resulting in a wide spectrum of malignancies caused by germline mutations in mismatch repair genes (MMR). Gene mutations have different effects and penetrance between the two genders. The aim of this review is to offer a gender-specific evidence-based clinical guide on diagnosis, screening, surveillance, and counselling of UTUC patients with LS.

A case of respiratory toxigenic diphtheria: contact tracing results and considerations following a 30-year disease-free interval, Catalonia, Spain, 2015.

In May 2015, following a 30-year diphtheria-free interval in Catalonia, an unvaccinated 6-year-old child was diagnosed with diphtheria caused by toxigenic . After a difficult search for equine-derived diphtheria antitoxin (DAT), the child received the DAT 4 days later but died at the end of June. Two hundred and seventeen contacts were identified in relation to the index case, and their vaccination statuses were analysed, updated and completed.

[Evaluation of the autochthonous transmission risk of Zika virus and other emerging mosquito-borne viral diseases in Catalonia (Spain)].

The recent Zika virus epidemic has highlighted the potential risk of introducing the arbovirosis to Europe, especially within the Mediterranean region where the vector, Aedes albopictus, has become established as an invasive species. In this context, a comprehensive evaluation of the risk of introducing the Zika virus and other mosquito-borne viruses of public health importance in Catalonia (Spain) was carried out. This article summarises the results of the preliminary assessment and the recommendations for the public health preparedness and response plan against the threat posed by these emerging diseases.

[Ebola alert: results and challenges in public health. A view from Catalonia (Spain)].

The Ebola outbreak in Guinea Conakry was notified to the World Health Organization (WHO) in March 2014. It is the most complex Ebola outbreak to date, affecting Guinea Conakry as well as the surrounding countries and with a risk of the disease spreading outside Africa. For this reason, the World Health Organization declared this Ebola outbreak an international public health emergency in August 2014.
