Highlights To what extent NAFLD is associated with glycemic remission among the general population remains unclear. The study elaborated that presence of NAFLD and fibrosis status decreased the chance of glycemic remission whereas NAFLD improvement mitigated glycemic deterioration, emphasizing joint management to liver‐focused subgroups of diabetes ...

Background – Because of the increased incidence of multidrug‐resistant (MDR) bacteria, the use of disinfectants over antibiotics has been encouraged. However, the interactions between disinfectants and host local immunity are poorly understood. Objective – To assess the effects of chlorhexidine digluconate (Chx), with and without selected host defence ...

Background – Canine atopic dermatitis (cAD) is a common chronic relapsing pruritic skin disease for which management commonly relies on life‐long use of immunomodulatory drugs. A number of the medications used are associated with adverse effects and the potential for complications during long‐term use.
