A SARS-CoV-2 Delta Variant Case Manifesting as Extensive Placental Infection and Fetal Transmission.

Introduction: Studies indicate a very low rate of SARS-CoV-2 detection in the placenta or occasionally a low rate of vertical transmission in COVID-19 pregnancy. SARS-CoV-2 Delta variant has become a dominant strain over the world and possesses higher infectivity due to mutations in its spike receptor-binding motif.

Case Presentation: To determine whether SARS-CoV-2 Delta variant has increased potential for placenta infection and vertical transmission, we analyzed SARS-CoV-2 infection in the placenta, umbilical cord, and fetal membrane from a case where an unvaccinated mother and her neonate were COVID-19 positive.

Proning modus operandi in pregnancies complicated by acute respiratory distress syndrome secondary to COVID-19.

Introduction: Prone positioning has been widely utilized in ARDS management before and during the COVID-19 pandemic due to its demonstrated mortality benefits. In pregnancy, proning requires careful attention to often overlooked physiologic changes in pregnancy and additional technical challenges accompanying a gravid abdomen. The purpose of this manuscript is to demonstrate a proning technique that was successfully used at our institution to avoid premature delivery of the fetus while improving maternal outcomes.

Graphite-type activated carbon from coconut shell: a natural source for eco-friendly non-volatile storage devices.

Carbon from biomass as an active material for supercapacitor electrodes has attracted much interest due to its environmental soundness, abundance, and porous nature. In this context, activated carbon prepared from coconut shells a simple activation process (water or steam as activation agents) was used as an active material in electrodes for eco-friendly supercapacitors. X-ray diffraction (XRD), Raman spectroscopy, conductivity, scanning electron microscopy (SEM), N sorption and thermogravimetry coupled to mass spectrometry (TGA-MS) studies revealed that activated carbon produced by this approach exhibit a graphitic phase, a high surface area, and large pore volume.

Surgical advances in the management of placenta accreta spectrum: establishing new expectations for operative blood loss.

Objective: To evaluate whether the implementation of our surgical approach, referred to in the text as Linear Cutter Vessel Sealing System (LCVSS) technique, will improve perioperative outcomes in patients with placenta accreta spectrum (PAS), specifically by reducing blood loss and blood transfusion rates at the time of cesarean hysterectomy (C-HYST). The LCVSS technique integrates the following: (1) hysterotomy performed using the Linear Cutter, (2) no placental manipulation, (3) cauterization of anatomically prominent vascular anastomosis using the handheld vessel sealing system, and (4) completion of bladder dissection until the cervico-vaginal junction before ligation and division of uterine arteries.

Materials And Methods: This is a retrospective cohort study that analyzed perioperative outcomes in patients undergoing C-HYST for PAS at a tertiary care center from 1 July 2014 to 1 December 2019.

An initiative to evaluate the safety of maternal bonding in patients with SARS-CoV-2 infection.

Background: In the last two decades, the world faced three epidemics caused by novel coronaviruses, namely, SARS-CoV in 2002, MERS-CoV in 2012, and the ongoing SARS-CoV-2 that started in late 2019. Despite a growing understanding of SARS-CoV-2 virology, epidemiology, and clinical management strategies, other aspects, such as mode of delivery, vertical transmission, and maternal bonding, remain controversial. The question we faced upon the decision to separate the neonates of SARS-CoV-2 positive mother is whether we follow the principle of "do no harm"?

Methods: This is a quality improvement project that analyzed all cases of SARS-CoV-2 positive pregnancies that delivered at a major health care system from March 1, 2020 to June, 1 2020.

A new two-dimensional sonographic approach to the assessment of the fetal hard and soft palates.

COVID-19 Barriers to Care for Pregnant Patients in Prolonged Isolation.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent responsible for coronavirus disease 2019 (COVID-19), continues to have a devastating impact on healthcare systems worldwide, and many questions remain unanswered. The effect of COVID-19 on the pregnant population is widely debated, and the unique risks in pregnancy have not yet been elucidated. What has been established, however, is the recommendation for healthcare workers to use personal protective equipment (PPE) for both contact and airborne precautions to prevent transmission of the pathogen-adding another barrier to care for vulnerable populations.

Does the Enlightened Youth Project See the Light? A New Enterprise for Youths at Risk.

The aim of the present research is to examine the relationship between participation in the Enlightened Youth project for youths at risk and integration in employment at the end of the process, type of employment, dropout from school, and enlistment in the army. A database was prepared containing information on all the youths (499 in number) who were admitted to a multidisciplinary day Centre for Youths at Risk in Israel, of whom 86 participated in the project. To match a comparison group to the youths participating in the project, the propensity score matching method was operated.

Vapor-Phase Formation of a Hole-Transporting Thiophene Polymer Layer for Evaporated Perovskite Solar Cells.

Homogeneous layer formation on textured silicon substrates is essential for the fabrication of highly efficient monolithic perovskite silicon tandem solar cells. From all well-known techniques for the fabrication of perovskite solar cells (PSCs), the evaporation method offers the highest degree of freedom for layer-by-layer deposition independent of the substrate's roughness or texturing. Hole-transporting polymers with high hole mobility and structural stability have been used as effective hole-transporting materials (HTMs) of PSCs.

Semi-Transparent Perovskite Solar Cells with ITO Directly Sputtered on Spiro-OMeTAD for Tandem Applications.

Detailed Investigation of Evaporated Perovskite Absorbers with High Crystal Quality on Different Substrates.

Dual-source vapor-phase deposition enables low-temperature fabrication of high-performance planar structure perovskite (CHNHPbI) solar cells (PSCs), applicable in tandem devices or for industrial production with high homogeneity. Herein, we report low-temperature fabrication of high-efficiency PSCs by dual-source vapor-phase deposition and significance of TiO surface modification with [6,6]-phenyl C butyric acid methyl ester (PCBM) on cell performance. Co-evaporation of PbI and CHNHI, as confirmed by X-ray diffraction and high-resolution transmission electron microscopy analyses, results in CHNHPbI layers with a well-crystallized tetragonal phase formed on both TiO and TiO/PCBM electron-transport layers (ETLs).
