- Islet autoantibodies are key markers for the diagnosis of type 1 diabetes. Since their discovery, they have also been recognized for their potential to identify at-risk individuals prior to symptoms. To date, risk prediction using autoantibodies has been based on autoantibody number; it has been robustly shown that nearly all multiple-autoantibody-positive individuals will progress to clinical disease. However, longitudinal studies have demonstrated that the rate of progression among multiple-autoantibody-positive individuals is highly heterogenous. Accurate prediction of the most rapidly progressing individuals is crucial for efficient and informative clinical trials and for identification of candidates most likely to benefit from disease modification. This is increasingly relevant with the recent success in delaying clinical disease in presymptomatic subjects using immunotherapy, and as the field moves toward population-based screening. There have been many studies investigating islet autoantibody characteristics for their predictive potential, beyond a simple categorical count. Predictive features that have emerged include molecular specifics, such as epitope targets and affinity; longitudinal patterns, such as changes in titer and autoantibody reversion; and sequence-dependent risk profiles specific to the autoantibody and the subject's age. These insights are the outworking of decades of prospective cohort studies and international assay standardization efforts and will contribute to the granularity needed for more sensitive and specific preclinical staging. The aim of this review is to identify the dynamic and nuanced manifestations of autoantibodies in type 1 diabetes, and to highlight how these autoantibody features have the potential to improve study design of trials aiming to predict and prevent disease.

- Humans began to leave lasting impacts on Earth’s surface starting 10,000 to 8000 years ago. Through a synthetic collaboration with archaeologists around the globe, Stephens et al. compiled a comprehensive picture of the trajectory of human land use worldwide during the Holocene (see the Perspective by Roberts). Hunter-gatherers, farmers, and pastoralists transformed the face of Earth earlier and to a greater extent than has been widely appreciated, a transformation that was essentially global by 3000 years before the present.Science, this issue p. 897; see also p. 865Environmentally transformative human use of land accelerated with the emergence of agriculture, but the extent, trajectory, and implications of these early changes are not well understood. An empirical global assessment of land use from 10,000 years before the present (yr B.P.) to 1850 CE reveals a planet largely transformed by hunter-gatherers, farmers, and pastoralists by 3000 years ago, considerably earlier than the dates in the land-use reconstructions commonly used by Earth scientists. Synthesis of knowledge contributed by more than 250 archaeologists highlighted gaps in archaeological expertise and data quality, which peaked for 2000 yr B.P. and in traditionally studied and wealthier regions. Archaeological reconstruction of global land-use history illuminates the deep roots of Earth’s transformation and challenges the emerging Anthropocene paradigm that large-scale anthropogenic global environmental change is mostly a recent phenomenon.

- Purpose To evaluate the efficacy and tolerability of prophylactic breast irradiation in reducing the incidence and severity of bicalutamide-induced gynecomastia and breast pain. Methods and materials In all, 106 men with prostate cancer (T1b–T4/Nx/M0) and no current gynecomastia/breast pain were enrolled in this randomized, sham-controlled, double-blind, parallel-group multicenter trial. Patients received either a single dose of electron beam radiotherapy (10 Gy) or sham radiotherapy. Bicalutamide (Casodex) 150 mg/day was administered for 12 months from the day of radiotherapy. Every 3 months, patients underwent physical examination and questioning about gynecomastia and breast pain. Results The incidence of investigator-assessed gynecomastia was significantly lower with radiotherapy vs. sham radiotherapy (52% vs. 85%; odds ratio [OR], 0.13; 95% confidence interval [CI], 0.04, 0.38; p < 0.001); direct questioning showed similar results. Fewer radiotherapy patients had ≥5 cm gynecomastia (measured by calipers; 11.5% vs. 50.0% for sham radiotherapy), and fewer cases were moderate-to-severe in intensity (21% vs. 48%). Similar proportions of radiotherapy and sham radiotherapy patients experienced breast pain (83% vs. 91%; OR, 0.25; 95% CI, 0.05, 1.27; p = 0.221); patients receiving radiotherapy experienced some reduction in its severity (OR, 0.44; 95% CI, 0.20, 0.97; p = 0.0429). Conclusions Prophylactic breast irradiation is an effective and well-tolerated strategy for prevention of bicalutamide-induced gynecomastia.
