RESUMO
OBJECTIVE: To analyze adherence to an oral contraceptive (OC) regimen and correlate results to participants' socio-demographic and behavioral characteristics. METHODS: Women were prospectively enrolled and followed for 6 months. At enrollment, subjects were given a card for recording daily pill intake; its completion was checked at 6 months when women completed a self-administered questionnaire. RESULTS: Out of 755 eligible subjects, 704 agreed to participate; 402 women completed 6 months of recording of use of an OC and properly filled the questionnaire. Good adherence was reported by 64% of participants; 20.9% missed one pill and 14.9% missed more than one pill. Mean number of missed pills per subject was 0.59 and mean number of pills delayed for less than 24 h was 1.18. Best adherence to a COC regimen was associated with evening time intake (p = 0.0019). No statistically significant associations of adherence with socio-demographic characteristics were found. Age was only marginally associated with having missed at least one pill. CONCLUSION: In the present study, a lower number of missed pills were observed than previously reported, but the proportion of missed pills was similar. No association with specific subject characteristics that could serve as markers of increased risk of nonadherence was found.

We presented the case of stillbirth in a paucisymptomatic mother affected by SARS-CoV-2. At gross examination, the placenta showed a diffuse marble appearance and a focal hemorrhagic area. Multiple areas of hemorrhagic or ischemic necrosis with central and peripheral villous infarctions and thrombosis of several maternal and fetal vessels with luminal fibrin and platelet deposition were observed. All lesions seemed to be synchronous. Virus particles were identified within the cytoplasm of endothelial cells using electron microscopy, whereas SARS-CoV-2 RNA was detected in the placental tissue using real-time reverse transcription-polymerase chain reaction. Here, fetal vascular malperfusion was associated with infection; in fact, electron microscopy images showed that marked SARS-CoV-2 endotheliotropism involved the intravillous fetal capillaries. Furthermore, we confirmed that syncytiotrophoblast is the major target cell type for SARS-CoV-2 infection of the placenta. In conclusion, the possible consequences of the action of the placentotropic SARS-CoV-2 included the occurrence of vertical transmission, as reported in the literature, and/or stillbirth: the latter possibility may be triggered by a hampered maternal and/or fetal perfusion of the placenta. The diffuse thrombosis and subsequent ischemia of fetal capillaries induced by COVID-19 cannot be predicted by standard clinical surveillance.
