ABSTRACT

BACKGROUND: Pancreatic cancer is an aggressive malignancy, surgery being the only potentially curative treatment. The systemic inflammatory response is an important factor in the development of cancer. There is still controversy regarding its role in pancreatic cancer. METHODS: Our study is a retrospective observational cohort study. We included patients diagnosed with pancreatic ductal adenocarcinoma (PDAC), who underwent surgical resection in our hospital, between January 2012 and December 2019. We gathered information from preoperative and postoperative blood tests. Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), prognostic nutritional index (PNI) and systemic immune-inflammation index (SII) were determined. RESULTS: We included 312 patients. All the immune-inflammatory scores assessed significantly changed after the surgery. The impact on overall survival of these markers showed that only some of the postoperative scores predicted survival: high PLR had a negative prognostic impact, while high lymphocyte and PNI values had a positive effect on overall survival. DISCUSSION: The circulating immune cells and their values integrated in the assessed prognostic scores suffer statistically significant changes after curative pancreatic surgery. Only the postoperative values of lymphocyte count, PLR, and PNI seem to influence the overall survival in PDAC. TRIAL REGISTRATION: ClinicalTrials.gov-identifier NCT05025371 .

ABSTRACT

Investigations of four roe deer corpses were carried out from May until October 2014, in the Veterinary Forensic Laboratory and in the Parasitic Diseases Clinic, in the Iasi Faculty of Veterinary Medicine. The roe deer were harvested by shooting during the trophy hunting season. The clinical examination of the shot specimens revealed the presence of a highly consistent number of extremely mobile apterous insects, spread on the face, head, neck, lateral body parts, abdominal regions, inguinal, perianal and, finally, all over the body. The corpses presented weakening, anemia and cutaneous modification conditions. Several dozen insects were prelevated in a glass recipient and preserved in 70º alcoholic solution in order to identify the ectoparasite species. The morphological characteristics included insects in the Diptera order, Hippoboscidae family, Lipoptena cervi species. These are highly hematophagous insects that by severe weakening are affecting the game health and trophy quality. Histological investigations of the skin revealed some inflammatory reactions caused by ectoparasite Lipoptena cervi. Lipoptena cervi was identified for the first time in Iasi County, Romania.(AU)


As investigações de quatro cadáveres de veados foram realizadas desde maio até outubro de 2014, no Laboratório Forense de Veterinária e na Clínica de Doenças Parasitárias, da Faculdade de Medicina Veterinária de Iasi. Os veados foram abatidos por tiro durante a temporada de caça troféu. O exame clínico dos espécimes revelou a presença de um número muito consistente de insetos ápteros extremamente móveis, espalhados pela face, pela cabeça, pelo pescoço, pelas partes do corpo laterais, pelas regiões abdominal, inguinal, perianal e, finalmente, por todo o corpo. Os cadáveres apresentavam condições de enfraquecimento, anemia e alterações cutâneas. Várias dezenas de insetos foram separados em um recipiente de vidro e preservados em solução alcoólica de 70º, a fim de se identificarem as espécies de ectoparasitos. As características morfológicas incluem os insetos da ordem Diptera, família Hippoboscidae, espécie Lipoptena Cervi. Estes são insetos hematófagos que estão enfraquecendo e afetando a qualidade de saúde de animais de caça e troféu. Investigações histológicas da pele revelaram algumas reações inflamatórias causadas pelo ectoparasita cervi Lipoptena. Lipoptena cervi foi identificado pela primeira vez no condado de Iasi, na Romênia.(AU)
