Abstract
The purpose of this study was to characterize risk factors and groups at risk among people with diabetes and prediabetes for increased hospital utilization. Electronic health records for all people who visited the emergency department (ED) and had type II diabetes mellitus (PWD) or prediabetes (PWPD) were collected. ED use, hospital admissions, demographics, and clinical characteristics were compared between the groups. Multivariable logistic regression was used to compare the odds of ED high utilization (HU) (3+ visits per year) and hospital admissions between PWD and PWPD with interactions for socioeconomic status, race, marital status, and total comorbidities. PWD had higher mean ED visits per year compared with PWPD (1.5 vs. 1.2) and were more likely to be admitted (57.3% vs. 34.9%). PWD had higher odds of ED HU (2.1 [1.6, 2.7]) and hospital admissions (1.9 [1.6, 2.1]). Among PWD, Black, not married, and those with more than one comorbidity had the highest odds of ED HU. Among PWPD, those of low SES, Black, and divorced had the higher odds of ED HU. Hospital admissions were a risk for PWD and PWPD with increasing comorbidities. Early recognition and identification of prediabetes and clear criteria for diagnosis could reduce ED visits and hospital admissions.

Abstract
With a rise in obesity and more patients opting for bariatric surgery, it becomes crucial to understand associated complications like postprandial hypoglycemia (PPH). After bariatric surgery, significant changes are seen in insulin sensitivity, beta cell function, glucagon-like peptide 1 (GLP-1) levels, the gut microbiome, and bile acid metabolism. And in a small subset of patients, exaggerated imbalances in these functional and metabolic processes lead to insulin-glucose mismatch and hypoglycemia. The main treatment for PPH involves dietary modifications. For those that do not respond, medications or surgical interventions are considered to reverse some of the imbalances. We present a few case reports of patients that safely tolerated GLP-1 agonists. However, larger randomized control trials are needed to further characterize PPH and understand its treatment.

Abstract
The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present images of the second touchdown site, finding that ejecta from the impact crater was present at the sample location. Surface pebbles at both landing sites show morphological variations ranging from rugged to smooth, similar to Ryugu's boulders, and shapes from quasi-spherical to flattened. The samples were returned to Earth on 6 December 2020. We describe the morphology of >5 grams of returned pebbles and sand. Their diverse color, shape, and structure are consistent with the observed materials of Ryugu; we conclude that they are a representative sample of the asteroid.

Abstract
A modern day light microscope has evolved from a tool devoted to making primarily empirical observations to what is now a sophisticated , quantitative device that is an integral part of both physical and life science research. Nowadays, microscopes are found in nearly every experimental laboratory. However, despite their prevalent use in capturing and quantifying scientific phenomena, neither a thorough understanding of the principles underlying quantitative imaging techniques nor appropriate knowledge of how to calibrate, operate and maintain microscopes can be taken for granted. This is clearly demonstrated by the well-documented and widespread difficulties that are routinely encountered in evaluating acquired data and reproducing scientific experiments. Indeed, studies have shown that more than 70% of researchers have tried and failed to repeat another scientist's experiments, while more than half have even failed to reproduce their own experiments. One factor behind the reproducibility crisis of experiments published in scientific journals is the frequent underreporting of imaging methods caused by a lack of awareness and/or a lack of knowledge of the applied technique. Whereas quality control procedures for some methods used in biomedical research, such as genomics (e.g. DNA sequencing, RNA-seq) or cytometry, have been introduced (e.g. ENCODE), this issue has not been tackled for optical microscopy instrumentation and images. Although many calibration standards and protocols have been published, there is a lack of awareness and agreement on common standards and guidelines for quality assessment and reproducibility. In April 2020, the QUality Assessment and REProducibility for instruments and images in Light Microscopy (QUAREP-LiMi) initiative was formed. This initiative comprises imaging scientists from academia and industry who share a common interest in achieving a better understanding of the performance and limitations of microscopes and improved quality control (QC) in light microscopy. The ultimate goal of the QUAREP-LiMi initiative is to establish a set of common QC standards, guidelines, metadata models and tools, including detailed protocols, with the ultimate aim of improving reproducible advances in scientific research. This White Paper (1) summarizes the major obstacles identified in the field that motivated the launch of the QUAREP-LiMi initiative; (2) identifies the urgent need to address these obstacles in a grassroots manner, through a community of stakeholders including, researchers, imaging scientists, bioimage analysts, bioimage informatics developers, corporate partners, funding agencies, standards organizations, scientific publishers and observers of such; (3) outlines the current actions of the QUAREP-LiMi initiative and (4) proposes future steps that can be taken to improve the dissemination and acceptance of the proposed guidelines to manage QC. To summarize, the principal goal of the QUAREP-LiMi initiative is to improve the overall quality and reproducibility of light microscope image data by introducing broadly accepted standard practices and accurately captured image data metrics.

Abstract
PURPOSE OF REVIEW Aligning HIV treatment services with patient preferences can promote long-term engagement. A rising number of studies solicit such preferences using discrete choice experiments, but have not been systematically reviewed to seek generalizable insights. Using a systematic search, we identified eleven choice experiments evaluating preferences for HIV treatment services published between 2004 and 2020. RECENT FINDINGS Across settings, the strongest preference was for nice, patient-centered providers, for which participants were willing to trade considerable amounts of time, money, and travel distance. In low- and middle-income countries, participants also preferred collecting antiretroviral therapy (ART) less frequently than 1 monthly, but showed no strong preference for 3-compared with 6-month refill frequency. Facility waiting times and travel distances were also important but were frequently outranked by stronger preferences. Health facility-based services were preferred to community- or home-based services, but this preference varied by setting. In high-income countries, the availability of unscheduled appointments was highly valued. Stigma was rarely explored and costs were a ubiquitous driver of preferences. While present improvement efforts have focused on designs to enhance access (reduced waiting time, travel distance, and ART refill frequency), few initiatives focus on the patient-provider interaction, which represents a promising critical area for inquiry and investment. If HIV programs hope to truly deliver patient-centered care, they will need to incorporate patient preferences into service delivery strategies. Discrete choice experiments can not only inform such strategies but also contribute to prioritization efforts for policy-making decisions.

Abstract
AIMS/HYPOTHESIS We aimed to characterise the immunogenic background of insulin-dependent diabetes in a resource-poor rural African community. The study was initiated because reports of low autoantibody prevalence and phenotypic differences from European-origin cases with type 1 diabetes have raised doubts as to the role of autoimmunity in this and similar populations. METHODS A study of consecutive, unselected cases of recently diagnosed, insulin-dependent diabetes (n = 236, ≤35 years) and control participants (n = 200) was carried out in the ethnic Amhara of rural North-West Ethiopia. We assessed their demographic and socioeconomic characteristics, and measured non-fasting C-peptide, diabetes-associated autoantibodies and HLA-DRB1 alleles. Leveraging genome-wide genotyping, we performed both a principal component analysis and, given the relatively modest sample size, a provisional genome-wide association study. Type 1 diabetes genetic risk scores were calculated to compare their genetic background with known European type 1 diabetes determinants. RESULTS Patients presented with stunted growth and low BMI, and were insulin sensitive; only 15.3% had diabetes onset at ≤15 years. C-peptide levels were low but not absent. With clinical diabetes onset at ≤15, 16-25 and 26-35 years, 86.1%, 59.7% and 50.0% were autoantibody positive, respectively. Most had autoantibodies to GAD (GADA) as a single antibody; the prevalence of positivity for autoantibodies to IA-2 (IA-2A) and ZnT8 (ZnT8A) was low in all age groups. Principal component analysis showed that the Amhara genomes were distinct from modern European and other African genomes. HLA-DRB1*03:01 (p = 0.0014) and HLA-DRB1*04 (p = 0.0001) were positively associated with this form of diabetes, while HLA-DRB1*15 was protective (p < 0.0001). The mean type 1 diabetes genetic risk score (derived from European data) was higher in patients than control participants (p = 1.60 × 10-7). Interestingly, despite the modest sample size, autoantibody-positive patients revealed evidence of association with SNPs in the well-characterised MHC region, already known to explain half of type 1 diabetes heritability in Europeans. CONCLUSIONS/INTERPRETATION The majority of patients with insulin-dependent diabetes in rural North-West Ethiopia have the immunogenetic characteristics of autoimmune type 1 diabetes. Phenotypic differences between type 1 diabetes in rural North-West Ethiopia and the industrialised world remain unexplained.

Abstract
OBJECTIVE Different exercise types may yield different outcomes in osteoarthritis (OA) subgroups. The objective was to directly compare effectiveness of two exercise programs for people with medial knee OA and co-morbid obesity. DESIGN We performed a participant- and assessor-blinded randomized controlled trial. 128 people ≥50 years with medial knee OA and body mass index ≥30 kg/m2 were recruited from the community. Interventions were home-based non-weight bearing (NWB) quadriceps strengthening or weight bearing (WB) functional exercise for 12 weeks. Primary outcomes were change in overall knee pain (numeric rating scale, range 0-10) and difficulty with physical function (Western Ontario and McMaster Universities Osteoarthritis Index, 0-68) over 12 weeks. Secondary outcomes included other pain measures, physical function, quality-of-life, global changes, physical performance, and lower-limb muscle strength. RESULTS 123 (96%) participants were retained. There was no evidence of a between-group difference in change in pain (mean difference 0.73 units (95% confidence intervals (0.05,1.50)) or function (2.80 units (-1.17,6.76)), with both groups reporting improvements. For secondary outcomes, the WB group had greater improvement in quality-of-life (-0.043 units (-0.085,-0.001)) and more participants reporting global improvement (overall: relative risk 1.40 (0.98,2.01); pain 1.47 (0.97,2.24); function 1.43 (1.04,1.98). Although adverse events were minor, more NWB group participants reported ≥1 adverse event (26/66 (39%) vs 14/62 (23%), p = 0.04). CONCLUSIONS Both exercise types similarly improved primary outcomes of pain and function and can be recommended for people with knee OA and obesity. WB exercise may be preferred given fewer adverse events and potential additional benefits on some secondary outcomes.

Abstract
OBJECTIVE The MHC region harbors the strongest loci for latent autoimmune diabetes in adults (LADA); however, the strength of association is likely attenuated compared with that for childhood-onset type 1 diabetes. In this study, we recapitulate independent effects in the MHC class I region in a population with type 1 diabetes and then determine whether such conditioning in LADA yields potential genetic discriminators between the two subtypes within this region. RESEARCH DESIGN AND METHODS Chromosome 6 was imputed using SNP2HLA, with conditional analysis performed in type 1 diabetes case subjects (n = 1,985) and control subjects (n = 2,219). The same approach was applied to a LADA cohort (n = 1,428) using population-based control subjects (n = 2,850) and in a separate replication cohort (656 type 1 diabetes case, 823 LADA case, and 3,218 control subjects). RESULTS The strongest associations in the MHC class II region (rs3957146, β [SE] = 1.44 [0.05]), as well as the independent effect of MHC class I genes, on type 1 diabetes risk, particularly HLA-B*39 (β [SE] = 1.36 [0.17]), were confirmed. The conditional analysis in LADA versus control subjects showed significant association in the MHC class II region (rs3957146, β [SE] = 1.14 [0.06]); however, we did not observe significant independent effects of MHC class I alleles in LADA. CONCLUSIONS In LADA, the independent effects of MHC class I observed in type 1 diabetes were not observed after conditioning on the leading MHC class II associations, suggesting that the MHC class I association may be a genetic discriminator between LADA and childhood-onset type 1 diabetes.

Abstract
OBJECTIVE Hyperglycemia is common in hospitalized patients with and without prior history of diabetes and is an independent marker of morbidity and mortality in critically and noncritically ill patients. Tight glycemic control using insulin has been shown to reduce cardiac morbidity and mortality in hospitalized patients, but it also results in hypoglycemic episodes, which have been linked to poor outcomes. Thus, alternative treatment options that can normalize blood glucose levels without undue hypoglycemia are being sought. Incretin-based therapies, such as glucagon-like peptide (GLP)-1 receptor agonists (RAs) and dipeptidyl peptidase (DPP)-4 inhibitors, may have this potential. METHODS A PubMed database was searched to find literature describing the use of incretins in hospital settings. Title searches included the terms "diabetes" (care, management, treatment), "hospital," "inpatient," "hypoglycemia," "hyperglycemia," "glycemic," "incretin," "dipeptidyl peptidase-4 inhibitor," "glucagon-like peptide-1," and "glucagon-like peptide-1 receptor agonist." RESULTS The preliminary research experience with native GLP-1 therapy has shown promise, achieving improved glycemic control with a low risk of hypoglycemia, counteracting the hyperglycemic effects of stress hormones, and improving cardiac function in patients with heart failure and acute ischemia. Large, randomized controlled clinical trials are necessary to determine whether these favorable results will extend to the use of GLP-1 RAs and DPP-4 inhibitors. CONCLUSIONS This review offers hospitalist physicians and healthcare providers involved in inpatient diabetes care a pathophysiologic-based approach for the use of incretin agents in patients with hyperglycemia and diabetes, as well as a summary of benefits and concerns of insulin and incretin-based therapy in the hospital setting.

Abstract
OBJECTIVE Intra-abdominal adhesions are associated with an increased risk of complications during repeat Cesarean section (CS), such as bladder and bowel injury, hemorrhage, infection and hysterectomy. We present a simple sonographic marker, the 'sliding sign' of the uterus, for the prediction of intra-abdominal adhesions in the third trimester of pregnancy in women undergoing repeat CS. METHODS This was a prospective observational study of pregnant women with a history of at least one Cesarean delivery evaluated by transabdominal ultrasound during the third trimester of an ongoing pregnancy. In order to diagnose intra-abdominal adhesions, we assessed a sonographic sign, the sliding of the uterus under the inner part of the fascia of the abdominal muscles during deep breathing. Women were considered to be at high risk for severe adhesions if uterine sliding was absent and at low risk in the presence of obvious or moderate uterine sliding. A comparison between sonographic findings and intra-abdominal adhesions observed during surgery was performed. RESULTS Of the 63 patients with one or more previous CS examined, 59 completed the study and underwent CS at our institution. In 16 of the 19 cases assigned to the high-risk group for severe adhesions due to absence of sliding of the uterus, the suspicion was confirmed at surgery. The prediction of low risk for adhesions was confirmed in 35 out of 40 patients. The sensitivity and specificity of the sliding sign in predicting presence of intra-abdominal adhesions in women undergoing repeat CS were 76.2% and 92.1%, respectively. Inter- and intraobserver correlation using Cohen's kappa coefficient were 0.52 and 0.77, respectively. CONCLUSION Our data show that a simple sonographic sign might be able to discriminate between high and low risk for intra-abdominal adhesions in patients with a history of Cesarean delivery. This technique may aid clinical decisions in patients undergoing repeat CS. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVE Latent autoimmune diabetes in adults (LADA) shares clinical features with both type 1 and type 2 diabetes; however, there is ongoing debate regarding the precise definition of LADA. Understanding its genetic basis is one potential strategy to gain insight into appropriate classification of this diabetes subtype. RESEARCH DESIGN AND METHODS We performed the first genome-wide association study of LADA in case subjects of European ancestry versus population control subjects (n = 2,634 vs. 5,947) and compared against both case subjects with type 1 diabetes (n = 2,454 vs. 968) and type 2 diabetes (n = 2,779 vs. 10,396). RESULTS The leading genetic signals were principally shared with type 1 diabetes, although we observed positive genetic correlations genome-wide with both type 1 and type 2 diabetes. Additionally, we observed a novel independent signal at the known type 1 diabetes locus harboring PFKFB3, encoding a regulator of glycolysis and insulin signaling in type 2 diabetes and inflammation and autophagy in autoimmune disease, as well as an attenuation of key type 1-associated HLA haplotype frequencies in LADA, suggesting that these are factors that distinguish childhood-onset type 1 diabetes from adult autoimmune diabetes. CONCLUSIONS Our results support the need for further investigations of the genetic factors that distinguish forms of autoimmune diabetes as well as more precise classification strategies.

Abstract
Slow slip events have been suggested to trigger subduction earthquakes. However, examples to date have been poorly recorded, occurring offshore, where data are sparse. Better understanding of slow slip events and their influence on subsequent earthquakes is critical for hazard forecasts. We analyze a well-recorded event beginning 6 months before the 2012 M w (moment magnitude) 7.6 earthquake in Costa Rica. The event migrates to the eventual megathrust rupture. Peak slip rate reached a maximum of 5 mm/day, 43 days before the earthquake, remaining high until the earthquake. However, changes in Mohr-Coulomb failure stress at the hypocenter were small (0.1 bar). Our data contradict models of earthquake nucleation that involve power law acceleration of slip and foreshocks. Slow slip events may prove useful for short-term earthquake forecasts.

Abstract
The use of hybrid materials, where a matrix sustains nanoparticles controlling the release of the chemotherapeutic drug, could be beneficial for the treatment of primary tumors prior or after surgery. This localized chemotherapy would guarantee high drug concentrations at the tumor site while precluding systemic drug exposure minimizing undesirable side effects. We combined bacterial cellulose hydrogel (BC) and nanostructured lipid carriers (NLCs) including doxorubicin (Dox) as a drug model. NLCs loaded with cationic Dox (NLCs-H) or neutral Dox (NLCs-N) were fully characterized and their cell internalization and cytotoxic efficacy were evaluated in vitro against MDA-MB-231 cells. Thereafter, a fixed combination of NLCs-H and NLCs-N loaded into BC (BC-NLCs-NH) was assayed in vivo into an orthotopic breast cancer mouse model. NLCs-H showed low encapsulation efficiency (48%) and fast release of the drug while NLCs-N showed higher encapsulation (97%) and sustained drug release. Both NLCs internalized via endocytic pathway, while allowing a sustained release of the Dox, which in turn rendered IC50 values below of those of free Dox. Taking advantage of the differential drug release, a mixture of NLCs-N and NLCs-H was encapsulated into BC matrix (BC-NLCs-NH) and assayed in vivo, showing a significant reduction of tumor growth, metastasis incidence and local drug toxicities.

Abstract
Electron heating at Earth's quasiperpendicular bow shock has been surmised to be due to the combined effects of a quasistatic electric potential and scattering through wave-particle interaction. Here we report the observation of electron distribution functions indicating a new electron heating process occurring at the leading edge of the shock front. Incident solar wind electrons are accelerated parallel to the magnetic field toward downstream, reaching an electron-ion relative drift speed exceeding the electron thermal speed. The bulk acceleration is associated with an electric field pulse embedded in a whistler-mode wave. The high electron-ion relative drift is relaxed primarily through a nonlinear current-driven instability. The relaxed distributions contain a beam traveling toward the shock as a remnant of the accelerated electrons. Similar distribution functions prevail throughout the shock transition layer, suggesting that the observed acceleration and thermalization is essential to the cross-shock electron heating.

Abstract
Background
Hyperglycemia leading to increased oxidative stress is implicated in the increased risk for the development of macrovascular and microvascular complications in patients with type 1 diabetes mellitus.
Methods and Results
A random subcohort of 349 participants was selected from the
DCCT
/
EDIC
(Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications) cohort. This included 320 controls and 29 cardiovascular disease cases that were augmented with 98 additional known cases to yield a case cohort of 447 participants (320 controls, 127 cases). Biosamples from
DCCT
baseline, year 1, and closeout of
DCCT
, and 1 to 2 years post‐
DCCT
(
EDIC
years 1 and 2) were measured for markers of oxidative stress, including plasma myeloperoxidase, paraoxonase activity, urinary F
2α
isoprostanes, and its metabolite, 2,3 dinor‐8
iso
prostaglandin F
2α
. Following adjustment for glycated hemoblobin and weighting the observations inversely proportional to the sampling selection probabilities, higher paraoxonase activity, reflective of antioxidant activity, and 2,3 dinor‐8
iso
prostaglandin F
2α
, an oxidative marker, were significantly associated with lower risk of cardiovascular disease (−4.5% risk for 10% higher paraoxonase,
P
<0.003; −5.3% risk for 10% higher 2,3 dinor‐8
iso
prostaglandin F
2α
,
P
=0.0092). In contrast, the oxidative markers myeloperoxidase and F
2α
isoprostanes were not significantly associated with cardiovascular disease after adjustment for glycated hemoblobin. There were no significant differences between
DCCT
intensive and conventional treatment groups in the change in all biomarkers across time segments.
Conclusions
Heightened antioxidant activity (rather than diminished oxidative stress markers) is associated with lower cardiovascular disease risk in type 1 diabetes mellitus, but these biomarkers did not change over time with intensification of glycemic control.

Abstract
Attention deficit hyperactivity disorder (ADHD) is accompanied by resting-state alterations, including abnormal activity, connectivity and asymmetry of the default-mode network (DMN). Concurrently, recent studies suggested a link between ADHD and the presence of polymorphisms within the gene BAIAP2 (i.e., brain-specific angiogenesis inhibitor 1-associated protein 2), known to be differentially expressed in brain hemispheres. The clinical and neuroimaging correlates of this polymorphism are still unknown. We investigated the association between BAIAP2 polymorphisms and DMN functional connectivity (FC) asymmetry as well as behavioral measures in ADHD adults. Resting-state fMRI was acquired from 30 ADHD and 15 healthy adults. For each subject, rs7210438 and rs8079626 within the gene BAIAP2 were genotyped. ADHD severity, impulsiveness and anger were assessed for the ADHD group. Using multivariate analysis of variance, we found that genetic features do have an impact on DMN FC asymmetry. In particular, polymorphism rs8079626 affects medial frontal gyrus and inferior parietal lobule connectivity asymmetry, lower for AA than AG/GG carriers. Further, when combining FC asymmetry and the presence of the rs8079626 variant, we successfully predicted increased externalization of anger in ADHD. In conclusion, a complex interplay between genetic vulnerability and inter-hemispherical DMN FC asymmetry plays a role in emotion regulation in adult ADHD.

Abstract
BACKGROUND In adulthood, autoimmune diabetes can present as non-insulin-requiring diabetes, termed as 'latent autoimmune diabetes in adults' (LADA). In this study, we investigated established type 1 diabetes (T1D) and type 2 diabetes (T2D) genetic loci in a large cohort of LADA cases to assess where LADA is situated relative to these two well-characterized, classic forms of diabetes. METHODS We tested the association of T1D and T2D GWAS-implicated loci in 978 LADA cases and 1057 non-diabetic controls of European ancestry using a linear mixed model. We then compared the associations of T1D and T2D loci between LADA and T1D and T2D cases, respectively. We quantified the difference in genetic risk between each given disease at each locus, and also calculated genetic risk scores to quantify how genetic liability to T1D and T2D distinguished LADA cases from controls. RESULTS Overall, our results showed that LADA is genetically more similar to T1D, with the exception of an association at the T2D HNF1A locus. Several T1D loci were associated with LADA, including the major histocompatibility complex region, as well as at PTPN22, SH2B3, and INS. Contrary to previous studies, the key T2D risk allele at TCF7L2 (rs7903146-T) had a significantly lower frequency in LADA cases, suggesting that this locus does not play a role in LADA etiology. When constrained on antibody status, the similarity between LADA and T1D became more apparent; however, the HNF1A and TCF7L2 observations persisted. CONCLUSION LADA is genetically closer to T1D than T2D, although the genetic load of T1D risk alleles is less than childhood-onset T1D, particularly at the major histocompatibility complex region, potentially accounting for the later disease onset. Our results show that the genetic spectrum of T1D extends into adult-onset diabetes, where it can clinically masquerade as T2D. Furthermore, T2D genetic risk plays a small role in LADA, with a degree of evidence for the HNF1A locus, highlighting the potential for genetic risk scores to contribute towards defining diabetes subtypes.

Abstract
Abstract
Purpose:Neoadjuvant therapy has been widely integrated in the treatment of locally advanced breast cancer. Over time, this strategy has been extended to include patients with earlier stage disease to allow for assessment of in vivo response to treatment. The aim of this study was to describe the national trends in neoadjuvant therapy for all invasive breast cancers with a particular focus on triple negative disease and HER2 status.
Methods: The National Cancer Database (NCDB), an oncology outcomes database that collects data from more than 1500 Commission on Cancer (CoC) accredited cancer programs, was queried for all women diagnosed with invasive breast cancer from 2006-2013. Patients with unknown systemic therapy sequence were excluded. Women were classified by whether or not they received neoadjuvant systemic, chemo and/or endocrine, therapy.
Results: We identified 1,221,976 cases that were eligible for this analysis. Of these, 29.7% were HER2 negative, 18.4% were classified as triple negative, and 8.9% received neoadjuvant systemic therapy. The percentage of patients receiving neoadjuvant therapy increased from 7.5% in 2006 to 9.8% in 2012 with a slight decrease to 9.5% in 2013. This increase in the use of neoadjuvant therapy over the time period was statistically significant (p<0.0001). There was a small increase in the percent of patients with HER2 positive status who received neoadjuvant therapy, from 5.7% in 2006 to 6.5% in 2013. During this time period, there was a 9% increase in the percent of triple negative patients who received neoadjuvant therapy (13.1% in 2016 to 22.1% in 2013).
Number and percent of patients who received/did not receive neoadjuvant therapy by year2006 (N=136117)2007 (N=143033)2008 (N=148888)2009 (N=154713)2010 (N=154040)2011 (N=162333)2012 (N=163395)2013 (N=159457)No Neoadjuvant Therapy | 125908 (92.5)131559 (91.98)136593 (91.74)141364 (91.37)139459 (90.53)146500 (90.25)147401 (90.21)144306 (90.5)Neoadjuvant Therapy | 10209 (7.5)11474 (8.02)12295 (8.26)13349 (8.63)14581 (9.47)15833 (9.75)15994 (9.79)15151 (9.5)
Conclusions: Over the time period from 2006-2013, there has been an apparent increase in the percentage of patients who received neoadjuvant therapy. This trend is accompanied by increases in the percentage of TNBC patients and in Her2 positive patients who received neoadjuvant therapy. Other factors and the joint effects of these factors on the observed increase in the use of neoadjuvant therapy are under evaluation to elucidate the basis for this observation in the NCDB data.

Abstract
Abstract
Background: The fibroblast growth factor receptors 1 and 2 (FGFR1 and FGFR2) have been reported as amplified in multiple solid tumors, including lung, breast and gastric cancers. The FGFR family of proteins is an attractive target for therapy due to the importance of FGFR signaling in the pathogenesis of diverse tumor types. However, pan-FGFR inhibitor have shown only modest efficacy in patients with FGFR1 or FGFR2 gene amplification as determined by fluorescence in situ hybridization (FISH). Gene copy number alterations may not be the optimal predictive biomarker since the targets of these drugs are FGFR proteins; recent findings suggest that direct measurement of the protein targets of FGFR inhibitor therapies may be necessary to assess their treatment efficacy. We therefore developed quantitative FGFR protein assays using selected reaction monitoring mass spectrometry (SRM-MS). We sought to correlate levels of FGFR1, FGFR2 and pan-FGFR (FGFR1-4) proteins as measured by SRM-MS with FGFR gene amplification status as determined by FISH.
Methods: Formalin-fixed, paraffin-embedded (FFPE) tissue sections from breast (n=18), esophageal (n=1), gastric (n=1), lung (n=2), and endometrial (n=1) tumors were obtained. A board-certified pathologist marked the tumor area for laser microdissection. Tumor cell proteins were extracted using the Liquid Tissue® process and subjected to SRM-MS for analysis of protein expression levels of FGFR1, FGFR2 and FGFR1-4, as well as other targetable proteins including MET, EGFR, and PD-L1. We compared FGFR protein levels with FGFR amplification defined as FGFR to CEP FISH ratio >2.2.
Results: Of 23 tumor samples analyzed, the pan-FGFR1-4 proteomic assay detected FGFR protein in 11 cases (protein expression range: 217.8-3199.5 amol/ug). Ten of these 11 samples (91%) showed FGFR gene amplification. Only a single non-amplified case showed protein expression (235.6 amol/ug). FGFR protein (of 1, 2, and 1-4) was undetectable in 12 samples, of which 5 (42%) harbored FGFR1 amplification. Two of 2 (100%) of FGFR2-amplified cases (average copy number=38) showed high FGFR2 protein expression (3063.0 and 3199.5 amol/ug). Sensitivity of the pan-FGFR1-4 assay was superior to single FGFR assays.
Conclusion: A subset of FGFR-amplified tumors does not express FGFR protein when assessed by highly-sensitive SRM-MS. Patients whose tumors do not express FGFR protein are not likely to respond to FGFR inhibitor therapy, as supported by previous findings in squamous cell lung tumors, in which FGFR1 mRNA and/or protein expression levels greatly outperformed FGFR1 gene copy number in predicting sensitivity to a pan-FGFR inhibitors. An approach combining quantitative proteomics and FISH analyses may accurately identify patients most likely to respond to anti-FGFR protein agents.

Abstract
Background GATA3 is pivotal for the development of T lymphocytes. While its effects in later stages of T cell differentiation are well recognized, the role of GATA3 in the generation of early T cell precursors (ETP) has only recently been explored. As aberrant GATA3 mRNA expression has been linked to cancerogenesis, we investigated the role of GATA3 in early T cell precursor acute lymphoblastic leukemia (ETP-ALL). Methods We analyzed GATA3 mRNA expression by RT-PCR (n = 182) in adult patients with T-ALL. Of these, we identified 70 of 182 patients with ETP-ALL by immunophenotyping. DNA methylation was assessed genome wide (Illumina Infinium® HumanMethylation450 BeadChip platform) in 12 patients and GATA3-specifically by pyrosequencing in 70 patients with ETP-ALL. The mutational landscape of ETP-ALL with respect to GATA3 expression was investigated in 18 patients and validated by Sanger sequencing in 65 patients with ETP-ALL. Gene expression profiles (Affymetrix Human genome U133 Plus 2.0) of an independent cohort of adult T-ALL (n = 83) were used to identify ETP-ALL and investigate GATA3low and GATA3high expressing T-ALL patients. In addition, the ETP-ALL cell line PER-117 was investigated for cytotoxicity, apoptosis, GATA3 mRNA expression, DNA methylation, and global gene expression before and after treatment with decitabine. Results In our cohort of 70 ETP-ALL patients, 33 % (23/70) lacked GATA3 expression and were thus defined as GATA3low. DNA methylation analysis revealed a high degree of GATA3 CpG island methylation in GATA3low compared with GATA3high ETP-ALL patients (mean 46 vs. 21 %, p < 0.0001). Genome-wide expression profiling of GATA3low ETP-ALL exhibited enrichment of myeloid/lymphoid progenitor (MLP) and granulocyte/monocyte progenitor (GMP) genes, while T cell-specific signatures were downregulated compared to GATA3high ETP-ALL. Among others, FLT3 expression was upregulated and mutational analyses demonstrated a high rate (79 %) of FLT3 mutations. Hypomethylating agents induced reversal of GATA3 silencing, and gene expression profiling revealed downregulation of hematopoietic stem cell genes and upregulation of T cell differentiation. Conclusions We propose GATA3low ETP-ALL as a novel stem cell-like leukemia with implications for the use of myeloid-derived therapies.

Abstract
Blood-brain barrier (BBB) dysfunction complicates central nervous system lupus, an important aspect of systemic lupus erythematosus. To gain insight into the underlying mechanism, vascular corrosion casts of brain were generated from the lupus mouse model, MRL/lpr mice and the MRL/MpJ congenic controls. Scanning electron microscopy of the casts showed loss of vascular endothelial cells in lupus mice compared with controls. Immunostaining revealed a significant increase in caspase 3 expression in the brain vascular endothelial cells, which suggests that apoptosis could be an important mechanism causing cell loss, and thereby loss of BBB integrity. Complement activation occurs in lupus resulting in increased generation of circulating C5a, which caused the endothelial layer to become 'leaky'. In this study, we show that C5a and lupus serum induced apoptosis in cultured human brain microvascular endothelial cells (HBMVECs), whereas selective C5a receptor 1 (C5aR1) antagonist reduced apoptosis in these cells, demonstrating C5a/C5aR1-dependence. Gene expression of initiator caspases, caspase 1 and caspase 8, and pro-apoptotic proteins death-associated protein kinase 1, Fas-associated protein (FADD), cell death-inducing DNA fragmentation factor 45 000 MW subunit A-like effector B (CIDEB) and BCL2-associated X protein were increased in HBMVECs treated with lupus serum or C5a, indicating that both the intrinsic and extrinsic apoptotic pathways could be critical mediators of brain endothelial cell apoptosis in this setting. Overall, our findings suggest that C5a/C5aR1 signalling induces apoptosis through activation of FADD, caspase 8/3 and CIDEB in brain endothelial cells in lupus. Further elucidation of the underlying apoptotic mechanisms mediating the reduced endothelial cell number is important in establishing the potential therapeutic effectiveness of C5aR1 inhibition that could prevent and/or reduce BBB alterations and preserve the physiological function of BBB in central nervous system lupus.

Abstract
Diagnosis of CNS infections remains a great challenge in patients with hematological disorders since symptoms might both be masked and be mimicked by other conditions such as metabolic disturbances or consequences from antineoplastic treatment. Thus, awareness of this complication is crucial and any suspicion of a CNS infection should lead to timely and adequate diagnostics and treatment to improve the outcome in this population. Infections of the central nervous system (CNS) are infrequently diagnosed in immunocompetent patients, but they do occur in a significant proportion of patients with hematological disorders. In particular, patients undergoing allogeneic hematopoietic stem-cell transplantation carry a high risk for CNS infections of up to 15%. Fungi and Toxoplasma gondii are the predominant causative agents. The diagnosis of CNS infections is based on neuroimaging, cerebrospinal fluid examination and biopsy of suspicious lesions in selected patients. However, identification of CNS infections in immunocompromised patients could represent a major challenge since metabolic disturbances, side-effects of antineoplastic or immunosuppressive drugs and CNS involvement of the underlying hematological disorder may mimic symptoms of a CNS infection. The prognosis of CNS infections is generally poor in these patients, albeit the introduction of novel substances (e.g. voriconazole) has improved the outcome in distinct patient subgroups. This guideline has been developed by the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO) with the contribution of a panel of 14 experts certified in internal medicine, hematology/oncology, infectious diseases, intensive care, neurology and neuroradiology. Grades of recommendation and levels of evidence were categorized by using novel criteria, as recently published by the European Society of Clinical Microbiology and Infectious Diseases.

Abstract
Abstract
Background
Well-established risk factors for breast cancer (BC) include family history, BRCA mutations and biopsies with atypical hyperplasia (AH) or lobular carcinoma in situ (LCIS). Several institutions have registries of these high-risk women but outcomes from these registries require large numbers and long follow-up. We sought to compare characteristics between high-risk populations and evaluate early outcomes.
Methods
Women enrolled in IRB-approved high risk registries at NYU Langone Medical Center (NYU) and University of Vermont (UVM) were evaluated for risk category, uptake of prevention and development of breast cancer. Descriptive statistics were used to summarize the data and Pearson's Chi-Square and Fisher's Exact Tests were performed to compare the variables of interest among the two high risk registries.
Results
Between 2003-14, 1035 women enrolled in these high risk registries. There were significant differences in age and risk characteristics but we found a 99% concordance of variables collected between both high risk registries. Among all risk groups there was a low uptake of prevention opportunities, with 8% taking chemoprevention and 7% undergoing risk-reducing surgeries. Women with AH/LCIS accounted for 66% of those choosing chemoprevention while women with BRCA mutations accounted for 76% of those undergoing risk-reducing surgeries. To date, 43 women (4%) have been diagnosed with breast cancer. 86% were diagnosed with stage 0-1 disease and 70% had moderate or poorly differentiated cancers. There was no significant difference in background risk characteristics when comparing those with breast cancer to those who have not yet developed breast cancer.

Conclusions
Despite the low uptake of chemoprevention and risk reducing surgery, only 4% of patients went on to develop breast cancer in the study period. The majority of cancers involved moderate or high-grade lesions and were early stage, suggesting a benefit to participation in surveillance programs. We have demonstrated a high degree of concordance between high risk registries, suggesting no barriers to multi-institutional collaboration. High risk registries represent an important resource for studies into methods to prevent breast cancer and improve outcomes from this disease.

Abstract
Abstract
Background: Current methods of intraoperative assessment of lumpectomy margins are limited. Previous studies have found a lower rate of re-excisions with the adjunctive use of the MarginProbe device (Dune Medical Devices Ltd, Israel). The purpose of this study was to compare the tumor characteristics and re-excision rates before and after the use of MarginProbe for patients who had breast conservation surgery (BCS) at our institution.
Methods: The Breast Cancer Database of our medical center was queried for patients who underwent BCS from 1/2010-3/2015 by three breast surgeons. 2 surgeons used the MarginProbe to direct excision of additional margins at the time of primary lumpectomy surgery and 1 surgeon performed routine 6-surface cavity shavings. We compared our historical data (1/2010-12/2014) to MarginProbe data (1/2015-4/2015). The following variables were included: age, mammographic breast density, tumor characteristics, and re-excision rates. Statistical analyses were performed using Pearson's Chi-Square and Fisher's Exact Tests.
Results: We had a total of 1201 women who had BCS among the 3 breast surgeons. The median age was 61 years. The median invasive size was 1.2 cm. Majority of cancers were early stage (stage 0, I), invasive ductal carcinoma (61%), ER-positive (86%), PR-positive (74%), and Her2Neu-negative (88%). These tumor characteristics were not statistically different in the pre- and post-MarginProbe groups. The majority of patients had dense breasts (51%) and density did not differ among the pre- and post-MarginProbe groups (p=0.86). For the surgeons who used the MarginProbe for margin assessment at the time of surgery, the re-excision rate fell from 17% to 0% and 35% to 20% during the 4-month period. In contrast, the surgeon who routinely performed 6-surface shavings had a re-excision rate that fell from 13% to 12% in the same time period. 88% of MarginProbe readings were false positive. There was one false negative reading.

Conclusions: Routine use of the MarginProbe device was associated with lower re-excision rates compared to historical data and concurrent 6-cavity shaving approach. Better intraoperative margin assessment and lower re-excision rates will decrease the burden of breast cancer on patients and the health care system and support the practice of breast conserving surgery.
