Introduction: In Australia, the usual approach to breast lesions where core biopsy returns an uncertain result ("B3" breast lesion) is to perform surgical diagnostic open biopsy (DOB). This is associated with patient time off work, costs of hospital admission, risks of general anaesthesia and surgical complications. The majority of B3 lesions return benign results following surgery. Vacuum assisted excision biopsy (VAEB) is a less invasive, lower cost alternative, and is standard of care for selected B3 lesions in the United Kingdom. Similar use of VAEB in Australia, could save many women unnecessary surgery. The aim of this study was to document our experience during the introduction of VAEB as an alternative to DOB for diagnosis of selected B3 lesions. Methods: The multidisciplinary team developed an agreed VAEB pathway for selected B3 lesions. Technically accessible papillary lesions, mucocele‐like lesions and radial scars without atypia measuring ≤ 15mm were selected. Results: Over a 7 month period, 18 women with 20 B3 lesions were offered VAEB. 16 women (18 lesions) chose VAEB over DOB. Papillomas were the commonest lesion type. All lesions were successfully sampled: 17/18 were benign. One lesion (6%) was upgraded to malignancy (ductal carcinoma in situ on VAEB, invasive ductal carcinoma at surgery). No major complications occurred. Patient satisfaction was high: 15/16 respondents would again choose VAEB over surgery. Conclusion: VAEB is a patient‐preferred, safe, well‐tolerated, lower‐cost alternative to DOB for definitive diagnosis of selected B3 breast lesions. [ABSTRACT FROM AUTHOR]

Radiometric dating methods are essential for developing geochronologies to study Late Quaternary environmental change and
210 Pb dating is commonly used to produce age-depth models from recent (within 150 years) sediments and other geoarchives. The past two centuries are marked by rapid environmental socio-ecological changes frequently attributed to anthropogenic land-use activities, modified biogeochemical cycles, and climate change. Consequently, historical reconstructions over this recent time interval have high societal value because analyses of these datasets provide understanding of the consequences of environmental modifications, critical ecosystem thresholds, and to define desirable ranges of variation for management, restoration, and conservation. For this information to be used more broadly, for example to support land management decisions or to contribute data to regional analyses of ecosystem change, authors must report all of the useful age-depth model information. However, at present there are no guidelines for researchers on what information should be reported to ensure210 Pb data are fully disclosed, reproducible, and reusable; leading to a plethora of reporting styles, including inadequate reporting that reduces potential reusability and shortening the data lifecycle. For example, 64% of the publications in a literature review of210 Pb dated geoarchives did not include any presentation of age uncertainty estimates in modeled calendar ages used in age-depth models. Insufficient reporting of methods and results used in210 Pb dating geoarchives severely hampers reproducibility and data reusability, especially in analyses that make use of databased palaeoenvironmental data. Reproducibility of data is fundamental to further analyses of the number of palaeoenvironmental data and the spatial coverage of published geoarchives sites. We suggest, and justify, a set of minimum reporting guidelines for metadata and data reporting for210 Pb dates, including an IEDA (Interdisciplinary Earth Data Alliance), LiPD (Linked Paleo Data) and generic format data presentation templates, to contribute to improvements in data archiving standards and to facilitate the data requirements of researchers analyzing datasets of several palaeoenvironmental study sites. We analyse practices of methods, results and first order interpretation of210 Pb data and make recommendations to authors on effective data reporting and archiving to maximize the value of datasets. We provide empirical evidence from publications and practitioners to support our suggested reporting guidelines. These guidelines increase the scientific value of210 Pb by expanding its relevance in the data lifecycle. Improving quality and fidelity of environmental datasets broadens interdisciplinary use, lengthens the potential lifecycle of data products, and achieves requirements applicable for evidenced-based policy support.

A 4-month-old boy had a faint, confluent, macular erythema involving the forehead, nose, and philtrum, and matlike telangiectases over the forehead and eyelids. The clinical features, course, and laboratory studies were characteristic of neonatal lupus erythematosus. He was otherwise healthy and the product of a preterm twin pregnancy complicated by the development of maternal HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome. The patient had elevated Ro(SSA) and La(SSB) antibody titers, and studies performed on maternal blood disclosed positive antinuclear antibodies and elevated Ro and La antibody titers.

The Pingry School's SMART Team (Students Modeling a Research Topic) has worked with Andrew Vershon to design and produce accurate three-dimensional physical models of Human SirT2 using state of the art rapid prototyping technology. SifT2 is NAD-dependent histone deacetylase that are points of regulation of transcriptional silencing. Sir2 and SirT2 have been characterized to form regulator complexes with other, silent information regulator proteins and is analogous by sequence similarity to Hstl but result in differing function and specificities. Discussion with Dr. Vershon, allowed the Pingry SMART Team to use a modified version of RasMol(RP-Rasmol)to design physical models of sirtuin proteins highlighting areas of each protein shown to be experimentally significant for function. These final designs were then exported as PLY files and are used to direct an automated ZCorp 3D Color Printer to build physical models of the proteins. These models are communication tools that can be used to enhance the further understanding of these pathways among the scientific community. [ABSTRACT FROM AUTHOR]
