Rosacea is a common, chronic skin disease that currently incurable. Although environmental factors influence rosacea, the genetic basis of rosacea not established. In this genome-wide association study, discovery group 22,952 individuals (2,618 cases and 20,334 controls) was analyzed, leading to identification two significant single-nucleotide polymorphisms (SNPs) associated with one which replicated in new 29,481 (3,205 26,262 controls). The confirmed SNP, rs763035 (P=8.0 × 10(-11) group;...

Abstract We report a genomics‐guided exploration of the metabolic potential brasilicardin producer strain Nocardia terpenica IFM 0406. Bioinformatics analysis whole genome sequence revealed presence biosynthetic gene cluster presumably responsible for generation formerly unknown nocobactin derivatives. Mass spectrometry‐assisted isolation led to identification three new siderophores, terpenibactins A ( 1 ), B 2 ) and C 3 which belong class nocobactins. Their structures were elucidated by...

Aim To determine the short‐term outcomes of Australian buprenorphine‐exposed mother/infant dyads. Methods Retrospective record review drug‐exposed mothers and infants in A ustralia. Groups were based on drug exposure: buprenorphine (55, 3.8%), non‐buprenorphine opiates ( O , 686, 48.6%) non‐opiates NO 671, 47.5%). Results More than 30% continued to use heroin (21, 38%) benzodiazepines (16, 29%). They more likely have child at risk concerns (29, 52.7%, P = 0.019) previous children placed...

Electronic consultations (eConsultations) are increasingly used to obtain specialist guidance, avoiding unnecessary face-to-face patient visits for certain clinical questions. During the COVID-19 pandemic, when in-person care was limited, eConsultations may have helped clinicians input guide care.To understand how use of changed during pandemic and whether trends in eConsultation utilization differed based on patient's payer primary language.This retrospective cohort study conducted at 6...

Abstract Advances in human epidermal growth factor receptor 2 (HER2)‐directed therapies have revolutionised the care of patients with HER2‐positive breast cancer. While adjuvant trastuzumab combination chemotherapy has dramatically improved prognosis for early‐stage disease, up to a quarter will develop recurrent disease. The standard‐of‐care treatment paradigm evolved introduction newer HER2‐directed and increasing use neoadjuvant systemic therapy, latter providing us important functional...

Taxane-based chemotherapy regimens are in widespread use as standard of care treatment for patients with early breast cancer, though rarely its can be complicated by taxane-induced pneumonitis (TIP). While cancer is the most diagnosed women worldwide, TIP remains under-described this setting. Key questions relate to incidence, diagnosis and management, potential predictive biomarkers, balance between life-threatening toxicity curatively intended treatment. At a single Australian institution,...

18 F-Fludeoxyglucose PET-CT (FDG) is increasingly used to stage breast cancer. Most cancers express the Oestrogen Receptor (ER) and Progesterone (PR), this subtype demonstrates lower activity on FDG imaging.
