ERYTHROGRAM PROFILE DURING POSTPARTUM PERIOD IN HOLSTEIN COWS

With the intention to evaluate the erythrogram profile during postpartum period in Holstein cows, 142 blood samples were collected from cows during the first 90 days after parturition. Blood samples were collected from clinically healthy cows that were non-reactive to the antigen of bovine leukosis virus (GP 51). These animals were divided into nine experimental groups based on the time of the postpartum sample collection. The blood samples were collected with EDTA and submitted to the following tests: erythrocyte counts, packed cell volume, hemoglobin concentration and calculated blood indices (MCV, MCH, MCHC). There was influence of the postpartum period on the erythrogram. These alterations were observed during the first 24 h after parturition. The hemoconcentration observed during the parturition disappeared during the first 24h of postpartum. Variation of the values were observed: red blood, 5.08 +/- 0.60 and 6.11 +/- 0.72 cells /mu L; hemoglobin concentration, 9.85 +/- 1.6 and 11.46 +/- 1,40 g/dL; packed cell volume, 27.9 +/- 3.3 and 31.9 +/- 3.6 %; MVC, 50.10 +/- 5.90 and 55.27 +/- 6.88 fL; MHC, 18.19 +/- 1.63 and 19.50 +/- 2.76 pg; MCHC, 34.83 +/- 2.07 and 36.88 +/- 1.67 %. The values of the hematological components obtained in this study did not exceed the limits of the reference values, obtained from cows raised within the state of Sao Paulo.

Effects of the etonogestrel-releasing contraceptive implant inserted immediately postpartum on maternal hemostasis: A randomized controlled trial

Introduction: The puerperium is the period of highest risk for thrombosis during a woman's reproductive life and it is an important time for initiating an effective contraceptive method in order to increase intergestational interval. Thus, the objective of the present study was to evaluated the effects of the etonogestrel (ENG)-releasing contraceptive implant inserted immediately postpartum on maternal hemostasis markers during the first six weeks of delivery. Materials and Methods: Forty healthy women aged 18 to 35 years-old were randomized to receive either the ENG-releasing implant 24-48 h after delivery (implant group; n=20) or nothing (control group) until the sixth postpartum week. Blood samples were collected at 24-48 h and at 6 weeks after delivery, and hemostatic variables, including fibrinogen, coagulation factors, protein C, free protein S, antithrombin, alpha 2-antiplasmin, plasminogen activator inhibitor 1, thrombin-antithrombin complex (TAT), prothrombin fragment (PF)1+2, and D-dimers, as well as normalized activated protein C sensitivity ratio (nAPCsr), thrombin time, activated partial thromboplastin time, and prothrombin time were evaluated. Results: Insertion of the ENG-releasing contraceptive implant did not change the physiological reduction in overall coagulation (TAT and PF1+2) and fibrinolysis (D-dimer) markers, or nAPCsr. Reductions in factors II, VII, X and fibrinogen and increases in factor V were greater in the control than in the implant group. Clotting factors remained within normal limits throughout the study. Conclusion: The ENG-releasing contraceptive implant inserted immediately postpartum did not have negative effects on physiological variations of the hemostatic system during the first 6 weeks postpartum.

Avaliação do impacto da prematuridade na saúde mental de puérperas

O presente estudo tem como objetivo comparar a ocorrência de sintomas de ansiedade e depressão em mães de bebês prematuros e mães de bebês a termo. Trata-se de um estudo transversal, descritivo, de abordagem quantitativa. As participantes (n=40) foram submetidas à avaliação de rastreamento executada como rotina pelo Serviço de Psicologia de um hospital filantrópico do interior paulista mediante a aplicação da Escala Hospitalar de Ansiedade e Depressão (HAD). Constatou-se que, entre as mães de bebês prematuros, 75% apresentavam sintomas clinicamente significativos de ansiedade e 50% apresentavam sintomas clinicamente significativos de depressão. Já entre as mães de bebês a termo, 65% não apresentavam sintomas clinicamente significativos de ansiedade e tampouco depressão. Ademais, a superioridade da pontuação média obtida pelas primeiras alcançou significância estatística. Os resultados corroboram a literatura, que sugere que a prematuridade tende a ter impacto negativo na saúde mental da mulher que vivencia essa situação.
