Background: Coeliac Disease (CD) affects up to 1.4% of children worldwide, with a rising global incidence. A less typical clinical presentation and the need for a life-long gluten exclusion diet raise challenges for diagnosis, management, and healthcare delivery with considerable impacts for CD patients and families as well as clinical services.

Purpose: To investigate clinicopathologic characteristics and prognosis in secretory breast carcinoma (SBC) and to determine chemotherapy benefits stratified by different subgroups.

Methods: SBCs and triple-negative invasive ductal carcinoma patients (TN-IDCs) were enrolled from three cancer centers between January 2011 and December 2020. SBCs were further divided into two subgroups: those with triple negativity (TN-SBCs) and those without (non-TN-SBCs).

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits.

Background: The effect of initial antiretroviral therapy (ART) class on cancer risk in people with HIV (PWH) remains unclear.

Setting: Cohort study of 36,322 PWH enrolled (1996-2014) in the North American AIDS Cohort Collaboration on Research and Design.

Methods: We followed individuals from ART initiation (protease inhibitor [PI]-, non-nucleoside reverse transcriptase inhibitor [NNRTI]-, or integrase strand transfer inhibitor [INSTI]-based) until incident cancer, death, loss-to-follow-up, 12/31/2014, 85 months (intention-to-treat analyses [ITT]), or 30 months (per-protocol [PP] analyses).

Roasting degrades the coffee compound mozambioside (1) into several products, including 17-O-β-D-glucosyl-11-hydroxycafestol-2-one (2), 11-O-β-D-glucosyl-16-desoxycafestol-2-one (3), 11-O-β-D-glucosyl-(S)-16-desoxy-17-oxocafestol-2-one (4), 11-O-β-D-glucosyl-15,16-dehydrocafestol-2-one (5), 11-O-β-D-glucosyl-(R)-16-desoxy-17-oxocafestol-2-one (6), bengalensol (7), and 11-hydroxycafestol-2-one (8). A UHPLC-MS/MS method was established to quantify 1-8 and monitor their formation during authentic coffee roasting. Concentrations of 1 and the dominant roasting products 4, 5, and 7 ranged from 21.
