Leishmaniose en Equateur : 6. Note épidémiologique et entomologique sur le foyer de leishmaniose de Zumba
La rĂ©gion de Zumba se trouve au sud de la province mĂ©ridionale amazonienne d'Equateur de Zamora-Chinchipe, considĂ©rĂ©e comme la seconde zone d'endĂ©mie leishmanienne de ce pays. Une enquĂȘte clinico-Ă©pidĂ©miologique a Ă©tĂ© effectuĂ©e sur 83 patients en dĂ©tection passive. De plus, tous les biotopes du foyer de Zumba, dont les habitations, ont Ă©tĂ© Ă©chantillonĂ©s, de fĂ©vrier Ă septembre 92, pour la rĂ©colte des phlĂ©botomes au piĂšge lumineux et sur appĂąt humain (2.547 phlĂ©botomes rĂ©coltĂ©s). La faune anthrophile est pauvre et trois espĂšces seulement ont Ă©tĂ© observĂ©es. #Lutzomyia serrana est une espĂšce abondante piquant mĂȘme de jour. #Lu. maranonensis est une nouvelle espĂšce proche de #Lu. nevesi. Lu. castanea, autre nouvelle espĂšce, est rare. La localisation de nombreuses lĂ©sions Ă la face suggĂšre, au moins en partie, une transmission domiciliaire, pour laquelle #Lu. serrana serait un candidat-vecteur possible Ă©tant donnĂ© son omniprĂ©sence et son anthropophile.

Prospective observational cohort study of the association between antiplatelet therapy, bleeding and thrombosis in patients with coronary stents undergoing noncardiac surgery
Background: The perioperative management of antiplatelet therapy in noncardiac surgery patients who have undergone previous percutaneous coronary intervention (PCI) remains a dilemma. Continuing dual antiplatelet therapy (DAPT) may carry a risk of bleeding, while stopping antiplatelet therapy may increase the risk of perioperative major adverse cardiovascular events (MACE).
Methods: Occurrence of Bleeding and Thrombosis during Antiplatelet Therapy In Non-Cardiac Surgery (OBTAIN) was an international prospective multicentre cohort study of perioperative antiplatelet treatment, MACE, and serious bleeding in noncardiac surgery. The incidences of MACE and bleeding were compared in patients receiving DAPT, monotherapy, and no antiplatelet therapy before surgery. Unadjusted risk ratios were calculated taking monotherapy as the baseline. The adjusted risks of bleeding and MACE were compared in patients receiving monotherapy and DAPT using propensity score matching.
Results: A total of 917 patients were recruited and 847 were eligible for inclusion. Ninety-six patients received no antiplatelet therapy, 526 received monotherapy with aspirin, and 225 received DAPT. Thirty-two patients suffered MACE and 22 had bleeding. The unadjusted risk ratio for MACE in patients receiving DAPT compared with monotherapy was 1.9 (0.93â3.88), P=0.08. There was no difference in MACE between no antiplatelet treatment and monotherapy 1.03 (0.31â3.46), P=0.96. Bleeding was more frequent with DAPT 6.55 (2.3â17.96) P=0.0002. In a propensity matched analysis of 177 patients who received DAPT and 177 monotherapy patients, the risk ratio for MACE with DAPT was 1.83 (0.69â4.85), P=0.32. The risk of bleeding was significantly greater in the DAPT group 4.00 (1.15â13.93), P=0.031.
Conclusions: OBTAIN showed an increased risk of bleeding with DAPT and found no evidence for protective effects of DAPT from perioperative MACE in patients who have undergone previous PCI
