Objective: The study's objective is to explore psychological distress (PD) among remote learners during COVID-19.

Participants: Female undergraduates matriculated at an NYC college in Winter 2020.

Methods: Using the Kessler-6 scale, we defined PD as no/low (LPD), mild/moderate (MPD), and severe (SPD) and assessed if residing in/near NYC modified associations.

Background: Blood group O candidates have lower lung transplantation rates despite having the most common blood group. We postulated that waitlist outcomes among these candidates and those with other blood types vary with disease severity and lung allocation score (LAS).

Methods: We performed a retrospective cohort study of 32,772 waitlist candidates using the United Network of Organ Sharing registry from May 2005 to 2020.

Importance: Hospital antimicrobial consumption data are widely available; however, large-scale assessments of the quality of antimicrobial use in US hospitals are limited.

Objective: To evaluate the appropriateness of antimicrobial use for hospitalized patients treated for community-acquired pneumonia (CAP) or urinary tract infection (UTI) present at admission or for patients who had received fluoroquinolone or intravenous vancomycin treatment.

Design, Setting, And Participants: This cross-sectional study included data from a prevalence survey of hospitalized patients in 10 Emerging Infections Program sites.

Background: In the 2011 US hospital prevalence survey of healthcare-associated infections and antimicrobial use 50% of patients received antimicrobial medications on the survey date or day before. More hospitals have since established antimicrobial stewardship programs. We repeated the survey in 2015 to determine antimicrobial use prevalence and describe changes since 2011.

Article Synopsis
  • The study investigates urinary tract infections (UTIs) and risk factors for multidrug resistant organisms (MDROs) in kidney transplant (KT) patients, revealing a lack of understanding regarding the burden and risks associated with these infections post-surgery.
  • Out of 743 KT patients analyzed, 106 experienced bacteriuria, with a significant number being asymptomatic and over a quarter having recurrent infections linked to MDROs, particularly Escherichia coli resistant to common antibiotics.
  • The findings suggest a notable link between obesity and MDRO presence in KT recipients and highlight the urgent need for new strategies to manage UTIs amid growing antimicrobial resistance challenges.

Background: A point-prevalence survey that was conducted in the United States in 2011 showed that 4% of hospitalized patients had a health care-associated infection. We repeated the survey in 2015 to assess changes in the prevalence of health care-associated infections during a period of national attention to the prevention of such infections.

Methods: At Emerging Infections Program sites in 10 states, we recruited up to 25 hospitals in each site area, prioritizing hospitals that had participated in the 2011 survey.

Zika virus infection during pregnancy can lead to congenital Zika syndrome. Implementation of screening programs and interpretation of test results can be particularly challenging during ongoing local mosquitoborne transmission. We conducted a retrospective chart review of 2,327 pregnant women screened for Zika virus in Miami-Dade County, Florida, USA, during 2016.
