Hunger and the transition from parenteral nutrition in hospitalized adults: A descriptive cohort study.

Background: Parenteral nutrition (PN) provides nutrition to patients who cannot use the digestive tract. Some patients experience delayed appetite recovery after PN, but the factors contributing to this remain unclear. This study aimed to investigate whether hospitalized patients receiving PN experience reduced hunger or appetite.

BMI and mortality in critically ill patients with COVID-19: another brick in the wall of the obesity paradox.

Objective: The objective of this study was to assess the existence of the obesity paradox in patients with COVID-19 admitted to the intensive care unit.

Methods: This was a multicentric retrospective cohort study including individuals aged 18 years or older admitted to the intensive care unit with SARS-CoV-2. Data were obtained from electronic medical records.

Decoupling of bird migration from the changing phenology of spring green-up.

The green-up of vegetation in spring brings a pulse of food resources that many animals track during migration. However, green-up phenology is changing with climate change, posing an immense challenge for species that time their migrations to coincide with these resource pulses. We evaluated changes in green-up phenology from 2002 to 2021 in relation to the migrations of 150 Western-Hemisphere bird species using eBird citizen science data.

The geographic extent of bird populations affected by renewable-energy development.

Bird populations are declining globally. Wind and solar energy can reduce emissions of fossil fuels that drive anthropogenic climate change, yet renewable-energy production represents a potential threat to bird species. Surveys to assess potential effects at renewable-energy facilities are exclusively local, and the geographic extent encompassed by birds killed at these facilities is largely unknown, which creates challenges for minimizing and mitigating the population-level and cumulative effects of these fatalities.
