Immune checkpoint inhibitors (ICIs) are at least as effective in patients with advanced non-small cell lung cancer (NSCLC) and mild preexisting interstitial lung disease (ILD) as those without ILD. However, the risk of checkpoint inhibitor pneumonitis (CIP) is higher in patients with the dual diagnoses and they need careful monitoring when introducing an ICI, a

Unlocking the mysteries behind Omicron’s unique set of mutations will be key to understanding how this virus evolves and spreads — particularly as a tougher-to-detect subvariant is taking off in various countries, threatening to prolong this wave of infections. The subvariant is known as BA.2 in the classification system used to catalogue mutations of SARS-CoV-2,

A new statement from the US Preventive Services Task Force (USPSTF) concludes that current evidence is insufficient to assess the balance of benefits and harms of screening for atrial fibrillation (AF) in asymptomatic adults.

Ninety-four percent of nurses report that there’s either “a lot” or “some” racism in their profession, according to a new survey. The primary area where racism is experienced by nurses is in their career paths (28.7%).

The studies, published January 20 in the journal Nature Medicine, also reinforce the importance of boosters worldwide. In one study, Samuel M.S. Cheng, of

The illness once dubbed a “pneumonia of unknown cause” in the early days of 2020 has revealed itself to be something far more strange. Two years into this pandemic, we now know COVID-19 can lead to a dizzying array of symptoms — from heart inflammation to brain fog to the loss of sense of smell
