MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The maturation of skin microbial communities during childhood is important for the skin health of children and development of the immune system into adulthood. This necessitates a better characterization of the environmental and genetic factors influencing these microbiome dynamics.
We investigated the skin microbiota of children (158 subjects between 1 and 10 years old) and their mothers using 16S rRNA gene amplicon sequencing. Sample location and age were the primary factors determining a child’s skin bacterial composition. Relative abundances of Streptococcus and Granulicatella were negatively correlated with age, and the alpha diversity at all body sites examined increased during the first 10 years of life, especially on the face. The facial bacterial composition of 10-year-old children was strongly associated with delivery mode at birth.

MedicalResearch.com: What is the background for this study?
Response: Psoriasis has been associated various inflammatory comorbidities including diabetes mellitus, coronary artery disease, etc. Moreover, obesity is prevalent among psoriasis patients and has been considered as an independent risk factor for occurrence and worsening of psoriasis by promoting systemic inflammation.
Notably, body weight (BW) gain of psoriasis patients after biologics use has been observed. However, there are inconsistent reports on whether biological therapy relates to BW gain.

MedicalResearch.com: What is the background for the risankizumab data presented at the American Academy of Dermatology 2019 Annual Meeting?
Response: Abstracts presented by AbbVie at the American Academy of Dermatology (AAD) 2019 Annual Meeting highlight additional data from the Phase 3 clinical trial program evaluating the safety and efficacy of risankizumab, an investigational interleukin-23 (IL-23) inhibitor. The registrational program for risankizumab evaluated more than 2,000 adult patients with moderate to severe plaque psoriasis across four pivotal studies.
