To describe the epidemiology of cystic ovarian disease (COD), to find possible risk factors associated with the incidence of cysts and to analyse the impact of COD on the reproductive performance of dairy cows, databases from 22 dairy herds from the main dairy region in Argentina were retrospectively evaluated throughout a 3-year period (2009-2011). A total of 248 COD cases over 9156 parturitions were recorded, resulting in a cumulative incidence rate of 2.7%. Cystic ovarian disease incidence density was lower during the first 100 days post-partum (DPP) than during later stages of lactation. Seasonality had a significant influence on the disease presentation with higher incidence rates during winter and spring. Cows with a previous diagnosis of clinical mastitis showed 2.72 times more chances of developing ovarian cysts. Cystic cows had longer calving to first service and calving to conception intervals and lower conception rate than controls.
Avaliar o tratamento utilizado e a classificação de peso de recém-nascidos (RN) de gestantes portadoras de Diabetes Mellitus Gestacional (DMG). Foi realizado um estudo transversal descritivo com gestantes portadoras de DMG, em gestação única, no período de abril de 2011 a fevereiro de 2016. Os dados avaliados foram o tipo de tratamento utilizado e a classificação de peso do RN. Foram avaliadas 893 gestantes. A dieta e a atividade física como única terapêutica foram utilizadas por 306 (34,3%), 366 (41%) necessitaram metformina, a associação de metformina e insulina foi necessária em 109 (12,2%) e utilizaram somente insulinoterapia 112 (12,5%) gestantes. Houve 27 (3,0%) RN pequenos para a idade gestacional (PIG), 687 (76,9%) RN adequados para a idade gestacional (AIG) e 179 (20,0%) RN grandes para a idade gestacional (GIG). A metformina foi a terapêutica mais utilizada e a maioria dos recém-nascidos foram AIG.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
