Preterm birth among women with and without severe acute respiratory syndrome coronavirus 2 infection.

Introduction: Studies directly comparing preterm birth rates in women with and without severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are limited. Our objective was to determine whether preterm birth was affected by SARS-CoV-2 infection within a large integrated health system in New York with a universal testing protocol.

Material And Methods: This retrospective cohort study evaluated data from seven hospitals in New York City and Long Island between March 2020 and June 2021, incorporating both the first and second waves of the coronavirus disease 2019 (COVID-19) pandemic in the USA.

Identification of topics for comparative effectiveness systematic reviews in the field of cancer imaging.

Aim: With rapid innovations in diagnostic and therapeutic interventions in cancer care, comparative effectiveness reviews (CERs) are essential to inform clinical practice and guide future research. However, the optimal means to identify priority CER topics are uninvestigated. We aimed to devise a transparent and reproducible process to identify ten to 12 CER topics in the area of cancer imaging relevant to a wide range of stakeholders.

Fiber geometry in the corpus callosum in schizophrenia: evidence for transcallosal misconnection.

Background: Structural abnormalities in the callosal fibers connecting the heteromodal association areas of the prefrontal and temporoparietal cortices bilaterally have been suggested to play a role in the etiology of schizophrenia.

Aims: To investigate for geometric abnormalities in these callosal fibers in schizophrenia patients by using a novel Diffusion-Tensor Imaging (DTI) metric of fiber geometry named Shape-Normalized Dispersion (SHD).

Methods: DTIs (3T, 51 gradient directions, 1.
