ATM and IRAK1 orchestrate two distinct mechanisms of NF-κB activation in response to DNA damage.

DNA damage in cells induces the expression of inflammatory genes. However, the mechanism by which cells initiate an innate immune response in the presence of DNA lesions blocking transcription remains unknown. Here we find that genotoxic stresses lead to an acute activation of the transcription factor NF-κB through two distinct pathways, each triggered by different types of DNA lesions and coordinated by either ataxia-telangiectasia mutated (ATM) or IRAK1 kinases.

Undernutrition in Cleft Palate Surgery: Effects on Postoperative Fistula Formation in a Tertiary Children's Hospital in Southern Africa.

Background: Cleft palate surgery can be complicated by fistula development. It is well known that undernutrition in general leads to more postoperative complications. However, little is known about postoperative fistula development after cleft palate surgery in low- and middle-income countries (LMIC's).

Disruption of the intestinal clock drives dysbiosis and impaired barrier function in colorectal cancer.

Diet is a robust entrainment cue that regulates diurnal rhythms of the gut microbiome. We and others have shown that disruption of the circadian clock drives the progression of colorectal cancer (CRC). While certain bacterial species have been suggested to play driver roles in CRC, it is unknown whether the intestinal clock impinges on the microbiome to accelerate CRC pathogenesis.

"It's normal to be afraid": attacks on healthcare in Ouaka, Haute-Kotto, and Vakaga prefectures of the Central African Republic, 2016-2020.

Introduction: Attacks on healthcare have further weakened the already fragile health system in the Central African Republic. We investigated attacks on healthcare in three conflict-affected prefectures-Ouaka, Haute-Kotto, and Vakaga-from 2016 to 2020. The study aim was to gain an in-depth understanding of the immediate and long-term effects of attacks on healthcare workers, facilities, supply chain, quality of care, and other components of the health system.
