    BackgroundSickle cell disease (SCD) is associated with chronic hemolysis and painful episodes. Pregnancy accelerates sickle cell complications, including prepartum and postpartum vasoocclusive crisis, pulmonary complications, and preeclampsia or eclampsia. Fetal complications include preterm birth and its associated risks, intrauterine growth restriction, and a high rate of perinatal mortality. The purpose of this study was to evaluate pregnancy outcomes in patients with SCD who underwent planned preventive red blood cell exchange (RBCX). Study Design and MethodsWe retrospectively evaluated the complications of SCD in 37 pregnant patients. Patients with SCD who had undergone prophylactic RBCX were compared with a control group who had not undergone RBCX during pregnancy. ResultsForty-three exchange procedures were performed in 24 patients. The control group comprised 13 patients with a mean age of 27.43.3 years who had not undergone RBCX during pregnancy. Four of the five patients who developed a vasoocclusive crisis died. There was a significant difference in maternal mortality between the study and control groups (p=0.011). There was also a significant difference in the incidence of vasoocclusive crisis between the study and control groups. One fetal death occurred in the 20th gestational week in a patient in the control group, although there were no postpartum complications in either the babies or the mothers in the control group. ConclusionThis study has demonstrated that prophylactic RBCX during pregnancy is a feasible and safe procedure for prevention of complications. Given the decrease in the risks of transfusion, RBCX warrants further study.

    Aim Gender-related differences have been described in the clinical characteristics and management of patients with chronic heart failure with reduced ejection fraction (HFrEF). However, published data are conflictive in this regard. Methods We investigated differences in clinical and management variables between male and female patients from the ATA study, a prospective, multicentre, observational study that included 1462 outpatients with chronic HFrEF between January and June 2019. Results Study population was predominantly male (70.1%). In comparison to men, women with chronic HFrEF were older (66 +/- 11 years vs 69 +/- 12 years, P < .001), suffered more hospitalisations and presented more frequently with NYHA class III or IV symptoms. Ischaemic heart disease was more frequent in men, whereas anaemia, thyroid disease and depression were more frequent in women. No difference was seen between genders in the use rate of renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists, or ivabradine, or in the proportion of patients achieving target doses of these drugs. Regarding device therapies, men were more often treated with an implantable cardioverter-defibrillator (ICD) and women received more cardiac resynchronisation therapy. Conclusion In summary, although management seemed to be equivalent between genders, women tended to present with more symptoms, require hospitalisation more frequently and have different comorbidities than men. These results highlight the importance of gender-related differences in HFrEF and call for further research to clarify the causes of these disparities. Gender-specific recommendations should be included in future guidelines in HFrEF.
