ABSTRACT

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus has infected over 115 million people and caused over 2.5 million deaths worldwide. Yet, the molecular mechanisms underlying the clinical manifestations of COVID-19, as well as what distinguishes them from common seasonal influenza virus and other lung injury states such as Acute Respiratory Distress Syndrome (ARDS), remains poorly understood. To address these challenges, we combined transcriptional profiling of 646 clinical nasopharyngeal swabs and 39 patient autopsy tissues, matched with spatial protein and expression profiling (GeoMx) across 357 tissue sections. These results define both body-wide and tissue-specific (heart, liver, lung, kidney, and lymph nodes) damage wrought by the SARS-CoV-2 infection, evident as a function of varying viral load (high vs. low) during the course of infection and specific, transcriptional dysregulation in splicing isoforms, T cell receptor expression, and cellular expression states. In particular, cardiac and lung tissues revealed the largest degree of splicing isoform switching and cell expression state loss. Overall, these findings reveal a systemic disruption of cellular and transcriptional pathways from COVID-19 across all tissues, which can inform subsequent studies to combat the mortality of COVID-19, as well to better understand the molecular dynamics of lethal SARS-CoV-2 infection and other viruses.

ABSTRACT

Study Objective The purpose of this study was to assess the impact of the COVID-19 pandemic on surgical volume and emergency department (ED) consults across obstetric & gynecologic (OB/GYN) services at a hospital located in the national epicenter of the pandemic. Design Retrospective cohort study. Setting Tertiary-care academic medical center in a metropolitan city. Patients or Participants Women undergoing OB/GYN ED consults or surgical procedures. Interventions March 16th institutional COVID-19 mandate to hold all elective surgeries. Measurements and Main Results The volume and types of surgical cases and ED consults were compared before and after the COVID-19 mandate. During the pandemic, the volume of ED consults and GYN surgeries significantly decreased, while OB surgeries remained stable. The average weekly case volume for ED consults, GYN surgeries, and OB surgeries were 44.8, 34.8, and 38.6 cases respectively during the “pre-COVID” timeframe (February 1st to March 15th) versus 17.8, 7.2, and 40.9 cases respectively during the “post-COVID” timeframe (March 16th toApril 15th), representing a 60.3% decrease in ED consults (p=<0.01) and a 79.3% decrease in GYN surgical volume (p=<0.01). The distribution of GYN surgical case types also changed significantly during the pandemic with higher proportions of emergent surgeries for ectopics, miscarriages, and concern for cancer (p <0.001). Alternatively, the OB surgical volume and distribution of OB surgical case types remained relatively constant. Conclusion This study highlights how the pandemic has impacted the ways OB/GYN patients access and receive care. The OB surgeries remained stable during the COVID-19 pandemic reflecting the non-elective and time-sensitive nature of obstetric care. In contrast, ED consults and GYN surgeries decreased significantly. As expected, institutional policies suspending elective surgeries affected the volume and types of GYN surgeries performed during the pandemic, and the “stay-at-home” policy and personal fears of COVID-19 infection likely affected ED consult volumes.
