Perinatal outcomes and predictors of placental abruption: a retrospective study in an Ethiopian tertiary care center.

Background: Placental abruption is a critical obstetric condition characterized by the premature separation of the placenta from the uterus, leading to severe maternal and fetal complications. In Ethiopia, the maternal and perinatal morbidity and mortality rates are alarmingly high, and placental abruption significantly contributes to these adverse outcomes. Despite its severity, there is a lack of comprehensive data on the burden, risk factors, and outcomes associated with placental abruption in the Ethiopian context.

Impact of American College of surgeons trauma verification on statewide collaborative outcomes.

Background: American College of Surgeons (ACS) trauma center verification has demonstrated improved outcomes at individual centers, but its impact on statewide Trauma Quality Improvement Program (TQIP) Collaboratives is unknown. A statewide TQIP Collaborative, founded in 2011, noted underperformance in six of eight patient cohorts identified in the TQIP Collaborative report. We hypothesized that requiring ACS verification for level I and II trauma centers would result in improved outcomes for the state collaborative.

Rapid COVID-19 Testing of Symptomatic Health Care Personnel: A Strategy for Safely Maintaining the Workforce.

Determine performance characteristics and safety outcomes of two rapid COVID-19 screening methods to inform immediate return to work (RTW) decisions while (health care personnel) HCP await results of pending confirmatory laboratory test. Retrospective, occupational health quality improvement study comparing screening with rapid SARS-CoV-2 nucleic acid amplification (NAAT) and antigen test. 531 mildly symptomatic HCP screened over 16 months.

Intermolecular Interactions and Quantum Interference Effects in Molecular Junctions.

Destructive quantum interference (DQI) leads to a decrease in the conductance of certain well-documented molecules. Experimental observations have revealed both direct and indirect manifestations of DQI, although a comprehensive understanding of the underlying causes of these distinct outcomes remains elusive. In both cases, DQI lowers the conductance, but only the direct case exhibits a characteristic V-shaped dip in differential conductance.

High Molecular Conductance and Inverted Conductance Decay over 3 nm in Aminium-Terminated Carbon-Bridged Oligophenylene-Vinylenes.

With the progressing miniaturization of electronic device components to improve circuit density while retaining or even reducing spatial requirements, single molecules employed as electric components define the lower limit of accessible structural width. To circumvent the typical exponential conductance decay for increasing length in molecule-based wires, topological states, which describe the occurrence of discontinuities of a bulk material's electronic structure confined to its surface, can be realized for molecules by the introduction of unpaired spins at the molecular termini. The resulting high conductance and reversed conductance decay are typically only observed for shorter molecules, as the terminal spins must be within the electronic coupling range to produce the desired effects.
