Fetal movements and fetal heart rate (FHR) are well-established markers of fetal well-being and maturation of the fetal central nervous system. The purpose of this paper is to review and discuss the available knowledge on fetal movements and heart rate patterns in twin pregnancies. There is some evidence for an association or similarity in fetal movement incidences or FHR patterns between both members of twin pairs. However, the temporal occurrence of these patterns seems to be for the most part asynchronous, especially when stricter criteria are used to define synchrony. The available data suggest that fetal behavior is largely independent of sex combination, fetal position, and presentation. Conversely, chorionicity appears to have some influence on fetal behavior, mainly before 30 weeks of gestation. There is preliminary evidence for the continuity of inter-individual differences in fetal activity and FHR patterns over pregnancy. Comparisons between studies are limited by large methodological differences and absence of uniform concepts and definitions. Future studies with high methodological quality are needed to provide a more comprehensive knowledge of normal fetal behavior in twin pregnancy.

IntroductionHIV infection during pregnancy still raises controversial issues. Combined antiretroviral therapy (cART) has been successful in reducing mother‐to‐child transmission (MTCT). Routine screening in pregnancy and in pre‐conception consultation proved to be one of the best methods able to get this treatment on time. We review our experience with pregnant patients with HIV infection.Materials and MethodsRetrospective and descriptive study. Data obtained from HIV‐infected pregnant women from 1999 to 2012 with delivery and subsequent infectious diseases follow‐up at our hospital.ResultsWe evaluated 136 patients (169 pregnancies), with a total of 147 living newborns (2 twin pregnancies) and 1 stillbirth. Median age at pregnancy was 30 (SD 5.7) years. Four patients were HIV‐2 infected and one HIV‐1+2 infected. 26 (19.1%) women were HCV co‐infected and 6 (4.4%) HBV co‐infected; 1 patient has HCV and HBV co‐infection. Sexual risk for HIV acquisition was determined in 102 (75%) patients and 31 (22.8%) were intravenous drug users. 33/136 (24.2%) women were diagnosed on routine screening in pregnancy, 4 during delivery and 2 immediately after delivery. 36 (26.4%) patients had an AIDS‐defining entity before pregnancy and no new opportunistic infections were diagnosed. ART was used in 157 (92.9%) pregnancies and 15 (9.5%) of them were treated only with NRTIs. At the time of delivery 86/144 (59.7%) patients had undetectable viral load (VL) (25 patients without VL determined), 91.7% of those on ART. 119 (70.4%) had a TCD4 cell count above 200 cells/mm3. MTCT occurred in 3/147 cases (2%): in one mother HIV‐1 infection was diagnosed three weeks before delivery, other immediately after delivery and the third woman started cART (2NRTI+1PI/r) in the second trimester of pregnancy, always adherent and without secondary effects, VL at delivery was 50 copies/mL and elective C‐section was performed.ConclusionsThe fact that 24% of patients were diagnosed during pregnancy shows the importance of routine screening to all pregnant women. MTCT occurred in three children, but only one was administered cART for prevention.
