3D mixed perovskites have achieved substantial success in boosting solar cell efficiency, but the complicated perovskite crystal formation pathway remains mysterious. Here we present detailed crystallization kinetics of mixed perovskites FAMAPb(IBr), where FA is formamidinium and MA is methylammonium, with the addition of Cs to form a triple cation perovskite (3-CAT), in a comparison with the perovskite building block MAPbI (MAPI) via static grazing-incidence wide-angle X-ray scattering (GIWAXS) and micro-diffraction measurements. Spin-coated films produced α-perovskite peaks with no PbI or δ-intermediate phases, which was a promising result for the 3-CAT perovskite from micro-diffraction measurements.

Article Synopsis
  • - A molar pregnancy can co-occur with a normal fetus, which is quite rare and often leads to complications and poor outcomes; the case discussed involves a 26-year-old woman diagnosed with a complete molar pregnancy alongside a normal fetus.
  • - The patient initially chose to continue the pregnancy despite being advised to terminate due to risks like massive bleeding and was later hospitalized multiple times for bleeding and developed chorioamnionitis, requiring a surgical procedure at 25 weeks.
  • - The case highlights the complexities of managing such a rare situation, emphasizing the need for close monitoring and the risks involved, like the unfortunate neonatal death due to complications after delivery.

Key Clinical Message: There is a high association between umbilical cord hemangiomas or cysts with fetal mortality. However, favorable outcome is possible with proper prenatal monitoring and care.

Abstract: Umbilical cord hemangiomas are rare neoplasms of vascular origin, commonly found in the free section of the umbilical cord proximal to placental insertion.

Aim: Globally, one in seven infants is born with low birth weight and 3%-7% of infants are born with high birth weight, with the greatest burden noted in low- and middle-income countries. This study investigated the association between maternal prenatal glucose regulation and birth weight and the moderating effect of fetal sex among Pakistani women.

Methods: Secondary data from a prospective longitudinal study of healthy pregnant women from Pakistan (N = 189) was used.
