Impact of the COVID-19 pandemic on university students' psychological distress, well-being, and utilization of mental health services in the United States: populations at greatest risk.

Introduction: The COVID-19 pandemic led to major disruptions in the lives of university students, which is a population that is already at a greater risk of mental health concerns. Little is known about how the pandemic impacted distress and mental health services utilization among university students across the United States.

Methods: Using survey data from the National College Health Assessment, both before the COVID-19 pandemic (pre-March 2020,  = 88,986) and during the pandemic (Spring 2021,  = 96,489), the present study examined mental health symptoms and utilization of mental health services among undergraduate students attending four-year universities in the United States.

Alcohol misuse among university students before and during COVID-19: The role of mental health.

: Examine predictors of alcohol misuse among university students amid the COVID-19 pandemic. : University students who completed the National College Health Assessment III before, during, and after the pandemic lockdown. : Using multivariable logistic regression, we examined associations between psychological functioning, time spent with family and friends, and problematic alcohol use.

The role of acidic residues and of sodium ion adduction on the gas-phase H/D exchange of peptides and peptide dimers.

Gas-phase H/D exchange is widely used for characterizing the structure of ions. However, many structural parameters that affect the rate of H/D exchange are poorly understood, which complicates the interpretation of experimental data. Here, the effects of sodium ion adduction on the rate of H/D exchange with D2O for a series of peptides and peptide dimers with varying numbers of acidic residues are described.
