In this work,we report long-term trends in the abundance and breeding performance of Adélie penguins(Pygoscelis adeliae)nesting in three Antarctic colonies(i.e.,at martin Point,South Orkneys Islands;Stranger Point/Cabo Funes,South Shetland Islands;and Esperanza/Hope Bay in the Antarctic Peninsula)from 1995/96 to 2022/*** yearly count data of breeding groups selected,we observed a decline in the number of breeding pairs and chicks in crèche at all colonies ***,the magnitude of change was higher at Stranger Point than that in the remaining ***,the index of breeding success,which was calculated as the ratio of chicks in crèche to breeding pairs,exhibited no apparent trend throughout the study ***,it displayed greater variability at martin Point compared to the other two colonies under *** the number of chicks in crèche of Adélie penguins showed a declining pattern,the average breeding performance was similar to that reported in gentoo penguin colonies,specifically,those undergoing a population increase(even in sympatric colonies facing similar local conditions).Consequently,it is plausible to assume a reduction of the over-winter survival as a likely cause of the declining trend observed,at least in the Stranger Point and Esperanza ***,we cannot rule out local effects during the breeding season affecting the Adélie population of martin Point.

Microangiopathic hemolytic anemia (MAHA) is a rare paraneoplastic syndrome and is typically associated with gastric adenocarcinoma. We report a 47-year-old woman who presented with asthenia, lower back pain and bleeding. Twelve years ago the patient underwent total gastrectomy due to gastric adenocarcinoma and achieved complete remission. The patient was diagnosed with MAHA and diffuses bone metastasis of signet ring cell adenocarcinoma of unknown origin and was treated successfully with polichemotherapy based on cisplatin and 5-fluorouracil.
