Fetal Diagn Ther 2021 Jun 15:1-7. Epub 2021 Jun 15.

BCNatal Fetal Medicine Research Center, Hospital Clínic and Hospital Sant Joan de Déu, University of Barcelona, Barcelona, Spain.

Introduction: Preterm prelabor rupture of membranes (PPROM) is a common complication after fetal surgeries. The aim of this study was to assess risk factors for and outcomes after PPROM following cord occlusion (CO) in monochorionic diamniotic (MCDA) pregnancies.

Methods: This was a retrospective cohort study of 188 consecutive MCDA pregnancies treated by bipolar or laser CO, either primarily because of discordant malformation (dMF) or severe selective fetal growth restriction (sFGR), or secondarily when complete bichorionization was not possible in case of twin-to-twin transfusion syndrome (TTTS) or sFGR.

Synthesis of vector nonuniformly correlated light beams by a single digital mirror device.

Opt Lett 2021 Jun;46(12):2996-2999

We present a stable and flexible way to generate the vector nonuniformly correlated (NUC) beams with a compact optical system that involves only a single digital mirror device and a common-path interferometer. The system provides near real-time generation and accurate control of the phase difference between the orthogonal field components of the vector NUC beams. We discuss the methodology based on the vectorial pseudo-mode decomposition of the cross-spectral density matrix of the beam. Read More

Novel Digital Technologies for Blood Pressure Monitoring and Hypertension Management.

Curr Cardiovasc Risk Rep 2021 9;15(8):11. Epub 2021 Jun 9.

Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA USA.

Purpose Of Review: Hypertension is common, impacting an estimated 108 million US adults, and deadly, responsible for the deaths of one in six adults annually. Optimal management includes frequent blood pressure monitoring and antihypertensive medication titration, but in the traditional office-based care delivery model, patients have their blood pressure measured only intermittently and in a way that is subject to misdiagnosis with white coat or masked hypertension. There is a growing opportunity to leverage our expanding repository of digital technology to reimagine hypertension care delivery. Read More

Changes in electromyographic activity, mechanical power, and relaxation rates following inspiratory ribcage muscle fatigue.

Sci Rep 2021 Jun 14;11(1):12475. Epub 2021 Jun 14.

Dipartimento Di Elettronica, Informazione E Bioingegneria, Politecnico Di Milano, Milan, Italy.

Muscle fatigue is a complex phenomenon enclosing various mechanisms. Despite technological advances, these mechanisms are still not fully understood in vivo. Here, simultaneous measurements of pressure, volume, and ribcage inspiratory muscle activity were performed non-invasively during fatigue (inspiratory threshold valve set at 70% of maximal inspiratory pressure) and recovery to verify if inspiratory ribcage muscle fatigue (1) leads to slowing of contraction and relaxation properties of ribcage muscles and (2) alters median frequency and high-to-low frequency ratio (H/L).
