Defining the importance of landscape metrics for large branchiopod biodiversity and conservation: the case of the Iberian Peninsula and Balearic Islands

The deficiency in the distributional data of invertebrate taxa is one of the major impediments acting on the bias towards the low awareness of its conservation status. The present study sets a basic framework to understand the large branchiopods distribution in the Iberian Peninsula and Balearic Islands. Since the extensive surveys performed in the late 1980s, no more studies existed updating the information for the whole studied area. The present study fills the gap, gathering together all available information on large branchiopods distribution since 1995, and analysing the effect of human population density and several landscape characteristics on their distribution, taking into consideration different spatial scales (100 m, 1 km and 10 km). In overall, 28 large branchiopod taxa (17 anostracans, 7 notostracans and 4 spinicaudatans) are known to occur in the area. Approximately 30% of the sites hosted multiple species, with a maximum of 6 species. Significant positive co-occurring species pairs were found clustered together, forming 4 different associations of large branchiopod species. In general, species clustered in the same group showed similar responses to analysed landscape characteristics, usually showing a better fit at higher spatial scales.Brazilian Conselho Nacional de Desenvolvimento Cientifico e Tecnologico-CNPq [401045/2014-5]Spanish Ministry of Education, Culture and Sport [FPU014/06783]info:eu-repo/semantics/publishedVersio

Small cell carcinoma of pulmonary type inside a microinvasive mucinous cystadenocarcinoma of the ovary: a case report

We report the occurrence of a small cell carcinoma of pulmonary type developed within a large borderline mucinous cystic tumor of the ovary, with another focus of microinvasive mucinous adenocarcinoma, in a 32-year-old woman. The small cell carcinoma expresses several neuroendocrine markers, thyroid transcription factor 1 and parathyroid hormone. Carbohydrate antigen 15.3 and carcinoembryonic antigen were focally detected but not cancer antigen 125. Cytokeratin 20 was immunolabeled in several mucinous carcinomatous glands but not in the neuroendocrine cells. The p53 protein was abnormally abundant, including in the borderline tumor. Progesterone receptor was heterogeneously immunodetected, whereas estrogen receptor labeling was weak and limited. This unusual immunohistochemical pattern further enhances the singularity of this quite exceptional tumor association

Centralizing surgery for ovarian cancer in a ‘non-centralizing’ country (Belgium): the UNGO (UCLouvain Network of Gynaecological Oncology) experience

Objective In Belgium there is no centralization of surgery for ovarian cancer, with more than 100 centers treating around 800 cases per year. In 2017 a network with several collaborating hospitals was established to centralize surgery for ovarian cancer (UCLouvain Network of Gynecological Oncology; UNGO) following publication of the European Society of Gynecological Oncology (ESGO) recommendations and quality criteria for surgery of advanced ovarian cancer. We obtained ESGO accreditation in 2019. Methods We retrospectively collected data associated with patients undergoing surgery in our institution from 2007 to 2016, before the creation of the network (cohort 1) and, following the establishment of UNGO (2017–2021), patients undergoing surgery were prospectively registered in a REDCap database (cohort 2). The outcomes of the two cohorts were compared. Results A total of 314 patients underwent surgery in our institution from 2007 and 2021: 7.5 patients/year in cohort 1 (retrospective, 2007–2016) and 40.8 patients/year in cohort 2 (after network creation, 2017–2021). Median disease-free survival was increased from 16.5 months (range 13.2–20.4) in cohort 1 to 27.1 months (range 21.5–33.2) in cohort 2 (p=0.0004). In cohort 2, the rate of patients with residual disease at the end of the surgery was significantly less (18.7% vs 8.8%, p=0.023), although more patients in cohort 1 received neoadjuvant chemotherapy (89% vs 54%, p<0.001). However, there was a higher rate of complications in the patients in cohort 2 (18.8% vs 30%, p=0.041). Conclusion Our study shows that, with the help of ESGO and its recommendations, we have been able to create an efficient advanced ovarian cancer centralized network and this may provide an improvement in the quality of care
