Abstract
BACKGROUND AND PURPOSE The Systolic Blood Pressure Intervention (SPRINT) randomized trial demonstrated that intensive blood pressure management resulted in slower progression of cerebral white matter hyperintensities, compared with standard therapy. We assessed longitudinal changes in brain functional connectivity to determine whether intensive treatment results in less decline in functional connectivity and how changes in brain functional connectivity relate to changes in brain structure. MATERIALS AND METHODS Five hundred forty-eight participants completed longitudinal brain MR imaging, including resting-state fMRI, during a median follow-up of 3.84 years. Functional brain networks were identified using independent component analysis, and a mean connectivity score was calculated for each network. Longitudinal changes in mean connectivity score were compared between treatment groups using a 2-sample t test, followed by a voxelwise t test. In the full cohort, adjusted linear regression analysis was performed between changes in the mean connectivity score and changes in structural MR imaging metrics. RESULTS Four hundred six participants had longitudinal imaging that passed quality control. The auditory-salience-language network demonstrated a significantly larger decline in the mean connectivity score in the standard treatment group relative to the intensive treatment group (P = .014), with regions of significant difference between treatment groups in the cingulate and right temporal/insular regions. There was no treatment group difference in other networks. Longitudinal changes in mean connectivity score of the default mode network but not the auditory-salience-language network demonstrated a significant correlation with longitudinal changes in white matter hyperintensities (P = .013). CONCLUSIONS Intensive treatment was associated with preservation of functional connectivity of the auditory-salience-language network, while mean network connectivity in other networks was not significantly different between intensive and standard therapy. A longitudinal increase in the white matter hyperintensity burden is associated with a decline in mean connectivity of the default mode network.

Abstract
Organophosphates (OPs) are an integral part of modern agriculture; however, due to overexploitation, OPs pesticides residues are leaching and accumulating in the soil, and groundwater contaminated terrestrial and aquatic food webs. Acute exposure to OPs could produce toxicity in insects, plants, animals, and humans. OPs are known for covalent inhibition of acetylcholinesterase enzyme in pests and terrestrial/aquatic organisms, leading to nervous, respiratory, reproductive, and hepatic abnormalities. OPs pesticides also disrupt the growth-promoting machinery in plants by inhibiting key enzymes, permeability, and trans-cuticular diffusion, which is crucial for plant growth. Excessive use of OPs, directly/indirectly affecting human/environmental health, raise a thoughtful global concern. Developing a safe, reliable, economical, and eco-friendly methods for removing OPs pesticides from the environment is thus necessary. Bioremediation techniques coupled with microbes or microbial-biocatalysts are emerging as promising antidotes for OPs pesticides. Here, we comprehensively review the current scenario of OPs pollution, their toxicity (at a molecular level), and the recent advancements in biotechnology (modified biocatalytic systems) for detection, decontamination, and bioremediation of OP-pesticides in polluted environments. Furthermore, the review focuses on onsite applications of OPs degrading enzymes (immobilizations/biosensors/others), and it also highlights remaining challenges with future approaches.

Abstract
BACKGROUND To compare periodontal treatment responses in electronic cigarette (e-cigarette) users, non-smokers, former and current smokers. METHODS In this retrospective clinical study, 220 patients with periodontitis were seen for baseline periodontal charting, professional-mechanical-plaque-removal (PMPR) and re-evaluation by postgraduate students. Sixty of these patients were former smokers, twenty were former smokers now using e-cigarettes, twenty current smokers, while all others (n = 120) were non-smokers. Effects of smoking status and treatment duration on clinical outcomes were analyzed by linear models using generalized least squares adjusted for known confounders. The primary outcome was "need for surgery" defined as number of sextants with ≥2 non-adjacent sites of probing depths (PD) ≥5 mm. RESULTS Compared with non-smokers, e-cigarette users had a less favorable treatment response after PMPR. This included statistically significant increased "need for surgery", as well as increased number of sextants with PD ≥5 mm, number of sites with PD >5 mm and mean PD. There were no statistically significant differences between e-cigarette users and current smokers. Former smokers responded statistically significantly better than e-cigarette users for the primary outcome as well as for the number of sextants and sites with PD ≥5 mm and mean PD. CONCLUSIONS Overall, e-cigarette users had a statistically significantly less favorable response to PMPR than non-smokers; their response was not statistically significantly different to those of current smokers. This, however, needs to be validated with further research in prospective clinical and observational studies in different populations.

Abstract
Abstract
Introduction
College students are at high risk for developing insomnia and co-morbid psychological distress. The aim of this research was to assess whether the lack of endogenous mindfulness was a risk factor for insomnia.
Methods
In order to address this issue, an archival analysis was conducted with a data set from MUN where the relationship between chronotype, mental health, sleep quality, and social support was assessed (n=3,160; 2,266 women; X̅age=22 years). The proband subsample of interest were subjects that completed the HADS, MEQ, the ISI, and the Mindful Attention Awareness Scale (MAAS). The MAAS is a 15 item self-report measure, where each item is scored on a six-point Likert scale. Scores range from 15-90, higher scores are indicative of greater mindfulness. In order to evaluate the relevance of mindfulness, the overall sample was split into two groups (endogenous mindfulness [average score of ≥4.2]): n=647; X̅age=22.4 years; nonendogenous mindfulness [average score of ≥4.2]: n=1,505; X̅age=22.04 years).
Results
Subjects (n=2,152) were between the ages of 18-35 (X̅=22+/- 3.72) and included primarily Caucasian individuals (86.6 %) and individuals who identified as female (71.7%). The means and ranges for the ISI, MAAS, and HADS were as follows: 9.0 + 5.6 (0-28), 3.7+.98 (1-6), and 5.3 + 3.9 (0-21), respectively. A correlation of -0.27 (p<0.001) was found for endogenous mindfulness (scale score range 1-6) and insomnia (scale score range 0-28) and -0.25 (p<0.001) for non-endogenous mindfulness (scale score range 1-6) and insomnia. Moderator analyses were conducted, and it was found that depression moderates the relationship between mindfulness and insomnia, (HADS depression, ΔR2 = .2, ΔF(3, 643)=57.6, p=.012, b=-.3, t(643)=-2.5 p< .05. Results should be interpreted with caution as the effect size was less than 0.1.
Conclusion
There was a relationship found, in both groups, between mindfulness and the ISI, where the scores on the ISI were lower when mindfulness was high. This suggests that there is a moderate linear relationship between mindfulness and insomnia. This association needs to be further evaluated in samples that have a broader range of ISI scores and with analyses that more carefully parse the moderating influence of depression. Analyses are ongoing.

Abstract
Bioremediation systems coupled to efficient microbial enzymes have emerged as an attractive approach for the in-situ removal of hazardous organophosphates (OPs) pesticides from the polluted environment. However, the role of engineered enzymes in OPs-degradation is rarely studied. In this study, the potential OPs-hydrolase (opdH) gene (Arthrobacter sp. HM01) was isolated, cloned, expressed, and purified. The recombinant organophosphate hydrolase (ropdH) was ∼29 kDa; which catalyzed a broad-range of OPs-pesticides in organic-solvent (∼99 % in 30 min), and was found to increase the catalytic efficiency by 10-folds over the native enzyme (kcat/Km: 107 M-1s-1). The degraded metabolites were analyzed using HPLC/GCMS. Through site-directed mutagenesis, it was confirmed that, conserved metal-bridged residue (Lys-127), plays a crucial role in OPs-degradation, which shows ∼18-folds decline in OPs-degradation. Furthermore, the catalytic activity and its stability has been enhanced by >2.0-fold through biochemical optimization. Thus, the study suggests that ropdH has all the required properties for OPs bioremediation.

Abstract
Organophosphates (OPs) are hazardous pesticides, but an indispensable part of modern agriculture; collaterally contaminating agricultural soil and surrounding water. They have raised serious food safety and environmental toxicity that adversely affect the terrestrial and aquatic ecosystems and therefore, it become essential to develop a rapid bioremediation technique for restoring the pristine environment. A newly OPs degrading Arthrobacter sp. HM01 was isolated from pesticide-contaminated soil and identified by a ribotyping (16S rRNA) method. Genus Arthrobacter has not been previously reported in chlorpyrifos (CP) degradation, which shows 99% CP (100 mg L-1) degradation within 10 h in mMSM medium and also shows tolerance to a high concentration (1000 mg L-1) of CP. HM01 utilized a broad range of OPs pesticides and other aromatic pollutants including intermediates of CP degradation as sole carbon sources. The maximum CP degradation was obtained at pH 7 and 32 °C. During the degradation, a newly identified intermediate 2,6-dihydroxypyridine was detected through TLC/HPLC/LCMS analysis and a putative pathway was proposed for its degradation. The study also revealed that the organophosphate hydrolase (opdH) gene was responsible for CP degradation, and the opdH-enzyme was located intracellularly. The opdH enzyme was characterized from cell free extract for its optimum pH and temperature requirement, which was 7.0 and 50 °C, respectively. Thus, the results revealed the true potential of HM01 for OPs-bioremediation. Moreover, the strain HM01 showed the fastest rate of CP degradation, among the reported Arthrobacter sp.

Abstract
ABSTRACT A key requirement for the correct interpretation of high-resolution X-ray spectra is that transition energies are known with high accuracy and precision. We investigate the K-shell features of Ne , CO 2 , and SF 6 gases, by measuring their photo ion-yield spectra at the BESSY II synchrotron facility simultaneously with the 1s-np fluorescence emission of He-like ions produced in the Polar-X EBIT. Accurate ab initio calculations of transitions in these ions provide the basis of the calibration. While the CO 2 result agrees well with previous measurements, the SF 6 spectrum appears shifted by ∼ 0.5 eV, about twice the uncertainty of the earlier results. Our result for Ne shows a large departure from earlier results, but may suffer from larger systematic effects than our other measurements. The molecular spectra agree well with our results of time-dependent density functional theory. We find that the statistical uncertainty allows calibrations in the desired range of 1-10 meV, however, systematic contributions still limit the uncertainty to ∼ 40-100 meV, mainly due to the temporal stability of the monochromator energy scale. Combining our absolute calibration technique with a relative energy calibration technique such as photoelectron energy spectroscopy will be necessary to realize its full potential of achieving uncertainties as low as 1-10 meV.

Abstract
Background Closed method of pneumoperitoneum using Veress needle is an established technique. Classical closed technique is popular. Simple technique is a modified closed technique. Objective To compare the classical and simple techniques of closed pneumoperitoneum. Method This study was conducted in the department of urology, Bir hospital from August 1st 2019 to March 30th 2021. Total 114 patients were randomized into simple and classical technique of creating closed pneumoperitoneum. Time taken for creation of pneumoperitoneum, complications and failure of creating pneumoperitoneum in each group noted and analyzed. Chi square test, Fischer exact test and student t test were used and p < 0.05 considered significant. Result Among 114 patients, 61 in simple and 53 in classical technique allocated. In simple technique, mean age was 42.98±18.21 years, BMI was 21.84±2.57 kg/m2 , mean time for pneumoperitoneum creation was 108.07±21.14 seconds. In classical technique, mean age was 40.15±17.58 years, BMI was 21.94±2.54 (kg/m2 ), mean time for pneumoperitoneum creation was 189.70±32.21 seconds. Mean time was less in simple technique than classical technique (p < 0.001). Complication rate observed was 6% in each technique (p=0.797) with cumulative rate of 10%. Omental injury was seen in 3.2% in simple technique and 5.6% in classical technique (p=0.662). Retroperitoneal insufflation was seen in 6.5% in simple technique and 5.6% in classical technique (p=0.842). No failed pneumoperitoneum was observed in both groups. Conclusion Simple technique is as effective, reproducible and safe method as classical technique of creating closed pneumoperitoneum.

Abstract
BACKGROUND Patients with cancer may be at high risk of adverse outcomes from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We analyzed a cohort of patients with cancer and coronavirus 2019 (COVID-19) reported to the COVID-19 and Cancer Consortium (CCC19) to identify prognostic clinical factors, including laboratory measurements and anticancer therapies. PATIENTS AND METHODS Patients with active or historical cancer and a laboratory-confirmed SARS-CoV-2 diagnosis recorded between 17 March and 18 November 2020 were included. The primary outcome was COVID-19 severity measured on an ordinal scale (uncomplicated, hospitalized, admitted to intensive care unit, mechanically ventilated, died within 30 days). Multivariable regression models included demographics, cancer status, anticancer therapy and timing, COVID-19-directed therapies, and laboratory measurements (among hospitalized patients). RESULTS A total of 4966 patients were included (median age 66 years, 51% female, 50% non-Hispanic white); 2872 (58%) were hospitalized and 695 (14%) died; 61% had cancer that was present, diagnosed, or treated within the year prior to COVID-19 diagnosis. Older age, male sex, obesity, cardiovascular and pulmonary comorbidities, renal disease, diabetes mellitus, non-Hispanic black race, Hispanic ethnicity, worse Eastern Cooperative Oncology Group performance status, recent cytotoxic chemotherapy, and hematologic malignancy were associated with higher COVID-19 severity. Among hospitalized patients, low or high absolute lymphocyte count; high absolute neutrophil count; low platelet count; abnormal creatinine; troponin; lactate dehydrogenase; and C-reactive protein were associated with higher COVID-19 severity. Patients diagnosed early in the COVID-19 pandemic (January-April 2020) had worse outcomes than those diagnosed later. Specific anticancer therapies (e.g. R-CHOP, platinum combined with etoposide, and DNA methyltransferase inhibitors) were associated with high 30-day all-cause mortality. CONCLUSIONS Clinical factors (e.g. older age, hematological malignancy, recent chemotherapy) and laboratory measurements were associated with poor outcomes among patients with cancer and COVID-19. Although further studies are needed, caution may be required in utilizing particular anticancer therapies. CLINICAL TRIAL IDENTIFIER NCT04354701.

Abstract
Background:YLB113 is an etanercept biosimilar approved in all indications of its etanercept Reference Product (RP). Therapeutic equivalence in terms of clinical efficacy, safety and immunogenicity was previously demonstrated in a pivotal multicenter, double-blind, randomized, parallel-group, active-control, comparative study (YLB113-002) in rheumatoid arthritis (RA) subjects.1,2 Similar incidence of treatment emergent adverse events (TEAEs) was seen in both treatment arms except for injection site reactions (ISRs) and injection site erythema (ISE), both of which were less frequent in subjects treated with YLB113.Objectives:This post-hoc analysis was performed to further evaluate the differences in the incidence of ISRs and ISE during the 24 week treatment when the subjects with RA were treated with 50 mg of YLB113 or RP given once a week as a SC injection along with methotrexate.Methods:Safety analysis set (263 in YLB113 arm and 254 in RP arm) was considered for this analysis.Local reactions at the site of injection were assessed at each of eight study visits.The number of subjects who experienced ISRs and ISE were statistically compared for YLB113 and RP. The risk difference and 95% confidence interval (CI) were computed between arms to understand the magnitude of difference in the incidence of events. The statistical significance of between group difference was tested using chi-square test.Results:The result of this analysis showed a statistically significant difference in the incidences of ISRs and ISE between subjects who received YLB113 and RP. The risk difference between YLB113 and RP arms for ISR was -9.98% (95% CI, WALD -14.81%, -5.15%) and, for ISE it was -7.94% (95% CI, WALD -11.96%, - 3.92%; Table 1). This could be possibly explained by the absence of latex in the syringe needle cap of YLB113.3Table 1.Differences in ISRs and ISEs between YLB113 and Reference Product (RP)EventYLB113N=263RPN=254YLB113 vs RPNo of subjects with events [n(%)]No of subjects with events[n(%)])Risk Diff (95%CI, WALD)P-value (Chi-Square)Injection-site reactions10 (3.8%)35 (13.8%)-9.98% (-14.81%, -5.15%)<0.0001Injection-site erythema5 (1.9%)25 (9.8%)-7.94% (-11.96%, -3.92%)0.0001Conclusion:YLB113 has shown statistically significant lower incidences of ISRs (P-value <0.0001) and ISEs (P value 0.0001) compared to RP.

Abstract
Background:Eligible subjects with moderate-to-severely active rheumatoid arthritis (RA) who completed a phase 3 double-blind comparative efficacy and safety study (Study No. YLB113-002; Yamanaka et al, 2019) of 50 mg etanercept biosimilar (YLB113) or etanercept reference product (RP) by subcutaneous administration with concomitant MTX treatment for 52 weeks, were enrolled in this open label extension (OLE) study (Study No. YLB113-003) to assess the long-term safety and tolerability of YLB113 through to 3 years.Objectives:This OLE study aimed to evaluate the long-term safety of YLB113 administration in subjects with RA who received RP or YLB113 in a phase 3 active comparator study. The main parameters assessed were safety and tolerability in terms of adverse events (AEs) and injection site reactions (ISRs), incidence of immunogenicity and efficacy as DAS28 improvement (disease activity score in 28 joints).Methods:Subjects received 50 mg of YLB113 subcutaneously once every 1 to 2 weeks. Safety was assessed by AEs after study drug administration, ISRs, physical examination findings, and immunogenicity. Efficacy (DAS28 score) was assessed at the time of transition to the OLE study (Week 0), and at weeks 12, 24, 48, 72, 96 and at the end of the study.Results:201 (Full analysis set [FAS]) subjects received the study drug and 184 subjects completed the study (91.5% completion rate). The average drug exposure in 94 subjects who continued to receive YLB113 and completed the study (94.0% completion rate) and 90 subjects who switched from RP to YLB113 and completed the study (89.1% completion rate) was 103 weeks providing the long-term drug exposure data of YLB113.The CTCAE Grade of TEAEs and ADRs observed were Grade 2 or less in severity (with no Grade ≥3). The overall incidence of ISRs was 10.0% (20/201 subjects) 77 events. All the ISRs reported were Grade 1 except for one Grade 2.An overview of the AEs experienced by the subjects is summarized in the Table 1.Table 1.Overview of Adverse events in OLE studyFASn (%)Number of eventsNumber of subjects201-Treatment emergent adverse events (TEAEs)188(93.5)975Adverse drug reactions (ADRs)82(40.8)221Serious adverse events (SAEs)21(10.4)27Serious adverse drug reactions (SADRs)7(3.5)7AEs leading to premature study discontinuation4(2.0)6ADRs leading to premature study discontinuation3(1.5)4SAEs leading to premature study discontinuation3(1.5)4SADRs leading to premature study discontinuation2(1.0)2n - number of subjects with at least 1 AE in the categoryThe mean DAS28 (mean ± S.D.) of 2.22 ± 0.95 at the study transition was 2.10 ± 0.91 at Week 72 and 2.06 ± 0.89 at the end of the study. It was confirmed that DAS28 slightly decreased with time after the study transition and continued until the end of the study. The average DAS28 value remained low even with long-term administration of YLB113, suggesting that the effects of the study drug was sustained (Figure 1).Figure 1.DAS28 over time with YLB113 N: Number of subjects. * The administration period at the study completion differs for each subject, because the study transition time differs for each subject.cts who tested positive for anti-drug antibodies (ADA) at least once in the OLE study were 1.0% (2/200 subjects). All ADA were transient and disappeared at study completion. Such transient ADA formation was reported in the phase 3 study as well. In the phase 3 study, ADA formation was more frequent in subjects who received RP at 24 weeks, but all subjects were negative in the OLE study after switching. Therefore, switching did not affect immunogenicity.Conclusion:The safety, efficacy and immunogenicity profile of YLB113 was maintained over the long-term through to 3 years.

Abstract
We present absolute throughput analysis of several crystals for the Orion High-REsolution X-ray (OHREX) imaging crystal spectrometer using ray tracing and experimental measurements. The OHREX spectrometer is a high-resolution x-ray spectrometer designed to measure spectral line shapes at the Orion laser facility. The spectrometer is fielded with up to two spherical crystals simultaneously covering two independent spectral ranges. Each crystal has a nominal radius of curvature of R = 67.2 cm and is fielded at a nominal Bragg angle of 51.3°. To cover different bands of interest, several different crystals are available, including Ge (111), KAP, and several cuts of quartz, whose resolving power λ/Δλ exceeds 10 000. The calibrated response of the available crystals has previously been reported from measurements at the EBIT-I electron beam ion trap at Lawrence Livermore National Laboratory. Here, we model the absolute throughput of each crystal using ray tracing and verify the results using experimental data for the quartz (101¯1) crystal.

Abstract
We demonstrate a widely applicable technique to absolutely calibrate the energy scale of x-ray spectra with experimentally well-known and accurately calculable transitions of highly charged ions, allowing us to measure the K-shell Rydberg spectrum of molecular O_{2} with 8 meV uncertainty. We reveal a systematic ∼450 meV shift from previous literature values, and settle an extraordinary discrepancy between astrophysical and laboratory measurements of neutral atomic oxygen, the latter being calibrated against the aforementioned O_{2} literature values. Because of the widespread use of such, now deprecated, references, our method impacts on many branches of x-ray absorption spectroscopy. Moreover, it potentially reduces absolute uncertainties there to below the meV level.

Abstract
Interleukin-6 (IL6) is involved in pathogenesis of several autoimmune disorders including vitiligo. Hence, we aimed to investigate the association of IL6 -174 G/C and -572 G/C polymorphisms and its transcript levels with vitiligo; to evaluate the effect of IL-6 on normal human melanocyte (NHM) viability and expression of IL6R, MITF and TYR. IL6 -174 G/C and -572 G/C polymorphisms were genotyped by ARMS-PCR and PCR-RFLP respectively in 343 controls and 322 vitiligo patients. IL6 transcript levels were estimated from PBMCs (96 controls and 77 patients) and skin samples (15 controls and 15 patients) by qPCR. NHM viability was assessed by MTT; IL6R, MITF and TYR transcript and protein levels were monitored by qPCR and ICC respectively. Genetic analyses revealed no association of IL6 -174 G/C polymorphism (p> .05) with vitiligo. Analysis of IL6 -572 G/C revealed reduced risk of vitiligo in individuals with GC/CC genotypes compared to GG genotype (p = .010). IL6 expression was significantly increased (p = .0197) in PBMCs of patients. Further, IL6 expression was significantly higher in non-lesional skin compared to controls (p = .009). In-vitro NHM viability was decreased upon IL-6 exposure (10-50 ng/ml; p< .05), with significantly increased IL6R transcript (p = .042) and protein levels (p = .003) however, MITF transcript (p = .0003) and protein levels (p = .016), and TYR transcript levels (p = .001) were significantly decreased. The results suggest that IL6 -572 G/C polymorphism might be associated with vitiligo susceptibility in Gujarat population. Moreover, increased IL6 expression in vitiligo patients and its effect on NHM suggest a potential role in melanocyte biology. CONCLUSION The results suggest that IL6 - 572 G/C polymorphism might be associated with vitiligo susceptibility in Gujarat population. Moreover, increased IL6 expression in vitiligo patients and its effect on NHM suggest a potential role in melanocyte biology.

Abstract
Cushing syndrome in the paediatric age group is very difficult to diagnose due to atypical presenting features in children. Primary pigmented nodular adrenocortical disease (PPNAD) is a rare cause of ACTH-independent Cushing syndrome in children and it has characteristic gross and microscopic pathologic features. We report a case of PPNAD in a 16-year-old boy who was evaluated in our hospital with chief complaints of poor height velocity and rapid weight gain for 2-3 years before presentation. Proper evaluation showed ACTH-independent Cushing syndrome with normal imaging. Total bilateral adrenalectomy was performed followed by hormones replacement. 6 months after surgery, significant acceleration of height velocity was noticed. Patient also lost body weight and developed secondary sexual characteristics.

Abstract
AIMS To identify key gaps in the research evidence base that could help to improve the mental well-being of people with diabetes, and to provide recommendations to researchers and research funders on how best to address them. METHODS A 2-day international research workshop was conducted, bringing together research experts in diabetes and in mental health, people living with diabetes and healthcare professionals. RESULTS The following key areas needing increased financial investment in research were identified: understanding the mechanisms underlying depression; understanding the multifactorial impact of social stigma; improving the language used by healthcare professionals; supporting people who find it difficult to engage with their diabetes; supporting significant others; supporting people with diabetes and eating disorders; improving models of care by learning from best practice; the potential benefits of screening and managing diabetes distress in routine diabetes care pathways; primary prevention of mental health issues at the time of diagnosis of diabetes; establishing the effectiveness of diabetes therapies on mood and other mental health issues; and understanding the impact of current diabetes technologies on mental health. Research recommendations as to how to address each of these priority areas were also developed. CONCLUSIONS This inaugural position statement outlines recommendations to address the urgent unmet need related to the mental well-being of people living with diabetes, and calls on the research community and funders to develop research programmes and strategies to reduce this need.

Abstract
AIM To review all cases of B3 lesion diagnosed at initial image-guided needle biopsy over two 5-year cohorts to identify upgrade rates to malignancy and the effect of changing guidance on the management of such lesions. MATERIALS AND METHODS Data was collected retrospectively. Mammographic features, biopsy type and management were recorded for each lesion. Upgrade rates for each B3 histological category were quantified. Statistical analysis was performed using SPSS. RESULTS There were 224 cases in 2005-2010 and 240 cases in 2010-2015. Mammographically 211 lesions were microcalcifications, 182 masses, 65 distortions and six asymmetric densities with no difference in the mammographic features in the two cohorts. Two hundred and eight 14 G core biopsies and 256 initial vacuum-assisted biopsies were performed. There was a statistically significant reduction in benign surgical biopsies and an increase in second-line vacuum biopsy/excision in the latter cohort, with no significant change in the upgrade rate. There was an overall 6% upgrade to invasive malignancy and 13% upgrade to ductal carcinoma in situ (DCIS). The upgrade rates for the following histological categories were atypical intraductal epithelial proliferation (AIDEP) 33.2% (21/63); classical (not pleomorphic) in situ lobular neoplasia (ISLN) 18.2% (6/33); flat epithelial hyperplasia (FEA) 21.7% (20/92); papilloma with atypia 53.8% (7/13), without atypia 12.1% (8/66); and radial scar/complex sclerosing lesion with atypia 16.7% (2/12), and without atypia 7.9% (6/76). CONCLUSION Upgrade rates remain high for some histological categories even with first-line use of vacuum biopsy. Management of borderline lesions should be considered carefully in a multidisciplinary meeting. In many cases, the need for diagnostic surgical excision has been replaced by image-guided vacuum sampling.

Abstract
Abstract
Objective: Elderly patients with low-risk hormone-positive breast cancer are at risk of over treatment. Avoidance of radiation therapy (RT) in favor of endocrine therapy alone was first heralded as the optimal conservative strategy due to logistical simplicity, low acute sequelae and a reduction of contralateral cancers not seen with RT. However, long-term use of aromatase inhibitors (AI) is not without costs and morbidity, often leading to low compliance and notable late effects. We therefore performed a cost-effectiveness analysis to compare the outcomes and costs between AI for five years without RT versus hypofractionated RT alone without endocrine therapy.
Materials and Methods: Using data from available phase III trials and meta-analyses, we constructed a patient-level microsimulation Markov decision model to replicate the comparative outcomes between the strategies above from the societal perspective among 200,000 simulated patients. Five years of anastrozole was compared to a 15-fraction hypofractionated whole breast RT course without boost in a cohort of patients with low-risk disease as defined by CALGB 9343 entry criteria. Noncompliance with AI was modeled from recent population-based data. Relative effectiveness on ipsilateral breast tumor recurrence and contralateral breast cancers were based off the NSABP B-21 trial, adjusted to match the modern outcomes demonstrated in CALGB 9343 and PRIME II with further adjustment for AI over tamoxifen (ATAC, EBCTCG meta-analysis). Indirect costs of travel were accounted for, as were the costs of common and serious side-effects from RT (dermatitis, fibrosis, second malignancy, heart disease) and AI (arthralgia, hot flashes, osteopenia, fracture, thrombosis). A 1-year cycle time and lifetime horizon were used, with all costs adjusted to 2018 US dollars and extracted primarily from Medicare reimbursement data. The primary measure of efficacy was the quality-adjusted life-year (QALY) with age-adjusted utilities extracted from the literature. Half-cycle correction and a 3% discount rate were applied. Probabilistic sensitivity analysis was used to vary all parameters simultaneously.
Results: On average, RT was approximately $3,981 more expensive than endocrine therapy over the lifetime horizon. Under a number of assumptions, RT appeared similar in long-term effectiveness to AI therapy, with a difference of less than 0.03 quality-adjusted life years. Given the low value of the denominator in the incremental cost-effectiveness ratio (ICER), RT did not meet the formally defined $100,000/QALY threshold. On one-way sensitivity analysis, the ICER was particularly sensitive to the incidence and impact of salvage strategies for recurrence, treatment of contralateral breast cancers, cardiac events and fracture rates.
Conclusions: Modeling with the available evidence suggests it is likely that quality-of-life after RT-alone is nearly identical to an AI-alone strategy but associated with a small increase in cost. These results suggest select patients at risk of noncompliance can safely be treated with RT-alone rather than AI alone. Given the relative pros and cons of each strategy, RT-alone should be considered for select elderly low-risk breast patients.

Abstract
Abstract
Background: Electron intraoperative radiotherapy (IORT) can be used during breast conservation surgery to treat early-stage invasive breast cancer. While IORT may be an attractive alternative to traditional post-operative radiotherapy for many patients, its effectiveness in preventing local recurrence is still being evaluated. Using data from current clinical and observational studies, we aimed to assess the impact of single-fraction electron IORT on local recurrence rates.
Methods: Studies on single-fraction electron IORT during breast conservation surgery were identified through a search of PubMed and Google Scholar, as well as secondary referencing. Local recurrence rate was the main outcome of interest. Protocols from each publication were assessed for potential sources of heterogeneity. A meta-analysis of proportions, using binomial distribution to model the within-study variability and a random effects model, was conducted to estimate a pooled local recurrence rate. In order to estimate a 5-year recurrence rate, we applied a single-sample Poisson-normal model to model the probability of events occurring during a fixed period of time (60 months).
Results: A total of 13 independent publications were identified for abstraction. The analysis demonstrated a pooled monthly local recurrence rate of 0.02% per person-month (95% CI: 0.00 – 0.06%) for the studies with < 5 years of follow-up, 0.03% per person-month (0.02 – 0.06%) for studies with ≥ 5 years of follow-up, and 0.02% per person-month (0.01 – 0.04%) overall. Based on this model, the predicted 5-year recurrence rate is 2.7%, with a 95% confidence interval of 1.9% - 3.7%.
Conclusions: According to the published literature, the rate of breast cancer local recurrence after electron IORT was 0.02% per person-month; with an adjusted 5-year recurrence rate of 2.7%. These findings support the recent guidelines from the American Society for Radiation Oncology (ASTRO) supporting the use of electron IORT in low-risk patients.

Abstract
Abstract
Background: We report outcomes using prospective BIS surveillance in a high-risk cohort of patients who all underwent axillary lymph node dissection (ALND).
Methods: From 8/2010 through 12/2016, 206 consecutive patients were evaluated with BIS as part of a prospective surveillance program. 30 underwent ALND and constitute the study population. The program included pre-operative BIS measurement as well as post-operative assessments at regular intervals. Patients with L-Dex readings increasing by more than 10 from baseline were considered to have subclinical BCRL and treated with an over-the-counter (OTC) compression sleeve for 4 weeks. For the purpose of this analysis, additional high-risk features were defined as receipt of axillary radiation, a high body mass index (BMI) or the use of taxane based chemotherapy. Chronic BCRL was defined as the need for complex decongestive physiotherapy (CDP).
Results: Median follow-up was 36 months (range: 4.8-122.1 months). The median number of nodes removed was 18 (range: 5-32) and the median number of positive nodes was two. The median age for the cohort was 57.5 years old with 70% of patients undergoing mastectomy and the remainder breast conserving therapy. With respect to additional high-risk features, 77% also received taxane-based chemotherapy, 62% axillary irradiation, and 48% had an elevated BMI. Overall, 86% of patients had at least one additional high-risk feature, 70% at least two, and 23% had all three additional high-risk features. Seven patients (23%) had an elevated L-Dex score at some point during follow-up and underwent intervention with an OTC sleeve for 4 weeks. To date, no patients have required CDP at any time.
Conclusions: Prospective surveillance with BIS in a high-risk cohort of patients all undergoing ALND (plus additional high-risk features) led to no patients requiring CDP. These excellent findings are consistent with growing data supporting the use of BIS in prospective BCRL surveillance programs.

Abstract
Abstract
Background: We evaluated the impact of structured surveillance using bioimpedance spectroscopy (BIS) to prevent clinical BCRL in a group of high-risk (axillary lymph node dissection) patients.
Methods: From April 2010 through November 2016, 93 patients who were treated with axillary lymph node dissection (ALND) were prospectively monitored with BIS using L-Dex (Impedimed). Patients received a pre-operative baseline L-Dex measurement followed by post-operative assessments at regular intervals. An elevated L-Dex score was defined as an increase of ≥10 points above baseline (considered subclinical BCRL). Intervention consisted of applying an over the counter (OTC) sleeve for 4 weeks followed by re-evaluation. The need for complete decongestive physiotherapy (CDP) represented a surrogate for the development of clinically significant, chronic BCRL.
Results: Median follow-up was 24 months (range: 0.3-206.4 months). The median number of nodes removed was 19 (range: 5-41) and the median number of positive nodes was 3. Median age was 53 years old. Eighty five percent of patients underwent mastectomy and the remainder breast conserving therapy. 55% of patients received taxane based chemotherapy, 24% received some form of axillary RT (15% high tangents and 9% comprehensive regional nodal RT) and 74% had an elevated body mass index (BMI, > 25). Overall, 75% of these patients had at least one additional high-risk feature, 48% had at least two, and 6% had 3 (either taxane chemotherapy, axillary RT or elevated BMI). Thirty-three patients (35.4%) developed an elevated L-Dex score at some point during follow up. Overall, 10 patients (11%) required CDP at any point after treatment.
Conclusions: The results of this analysis support previously published data on the efficacy of prospective BCRL surveillance and early intervention using BIS. Of the 93 high-risk patients prospectively followed and managed in this structured BCRL protocol, 11% required CDP. These results compare favorably to all contemporary studies reporting BCRL rates in high-risk patients.

Abstract
Abstract
Background: With improved breast cancer outcomes, an increasing focus on sequelae of treatment as part of survivorship has emerged. Breast cancer related lymphedema (BCRL) represents one such sequelae. Increasing data and recent NCCN guidelines support the use of prospective BCRL surveillance to allow for early detection and intervention as a method to reduce chronic, irreversible BCRL. Therefore, this study was performed to evaluate the impact early detection and treatment of BCRL in breast cancer patients undergoing prospective surveillance with bioimpedance spectroscopy (BIS).
Methods: From 8/2010 through 12/2016, 206 patients were evaluated with BIS as part of a prospective surveillance program.The protocol included pre-operative assessment with BIS as well as post-operative assessments with BIS at regular intervals. Patients with L-Dex readings increasing by more than 10 from baseline were considered to have subclinical BCRL and treated with a compression sleeve for 4 weeks. For the purpose of this analysis, high-risk was defined as receipt of ALND, regional nodal irradiation, or taxane chemotherapy. Chronic BCRL was defined as the need for complex decongestive physiotherapy.
Results: A total of 206 patients were analyzed, with a mean age of 61 years old and a median follow up of 25.9 months. Overall, 17% of patients had least one high-risk feature, 8% had two factors, and 7% had all three factors. A total of 21 patients (9.8%) were diagnosed with subclinical BCRL. Increased rates of subclinical BCRL were seen in patients undergoing ALND (23% vs. 7%, p=0.01) with ALND and receipt of RNI associated with development of subclinical BCRL. At last follow-up, no patients had persistent, chronic BCRL following early, conservative intervention measures.
Conclusions: The results of this study support prospective surveillance and early treatment utilizing BIS. Intervention triggered by subclinical BCRL detection with an elevated L-Dex score was associated with a very low rate of chronic BCRL.

Abstract
Abstract
BACKGROUND: We established the olaparib tablet maximum tolerated dose (MTD) at 150 mg bid, dose limiting toxicities (DLT's) and response to therapy or carboplatin, paclitaxel and olaparib tablet given simultaneously, reported at ASCO 2014. This abstract will include data from both the phase 1b and the phase 2 expansion.
METHODS: A total of 54 subjects were evaluated in this trial, 14 in phase 1b and 40 in phase 2. Eligibility required measurable disease, adequate organ function and ECOG performance status of ~ 2. Subjects had to have failed first line platinum containing chemotherapy. BRCA testing was conducted as available. Subjects received the metronomic therapy of paclitaxel 60mg/m2 IV and carboplatin AUC 2 IV weekly, 3 weeks out of 4, and olaparib tablets at 150 mg bid administered orally for 3 consecutive days (D1-D3) every week for each cycle. Subjects were assessed for toxicity and response according to the protocol. Subjects that reached a confirmed complete remission were transitioned to olaparib tablets only, 300 mg bid until disease progression.
RESULTS: Median age was 58 and median number of prior regimens was 4. There have been no deaths due to the study regimen. One patient had grade 4 neutropenia and an allergic reaction to carboplatin. The common grade 3/4 toxicities were caused by the chemotherapy (neutropenia. anemia and thrombocytopenia). Two patients had mild GI toxicities. One patient had a skin rash. There was no evidence of cardiac, hepatic, or pulmonary toxicities in any of these patients. 25% of subjects had a complete remission (CR), 31% had PR, 23% had SD and 21% had
PD. Of the 13 CRs, 4 were BRCA negative. PFS median for BRCA positive subjects is 12.6 months vs 4.8 months for BRCA negative subjects. OS median for BRCA positive subjects is 24 months vs 16 months for BRCA negative subjects. All of the CR's are alive.
CONCLUSION: Olaparib tablet can be safely administered simultaneously with a weekly regimen of carboplatin and paclitaxel in heavily pretreated ovarian cancer patients. Olaparib appears to be highly effective in BRCA positive subjects. This is the first successful combination of olaparib tablets with carboplatin and paclitaxel that has been well tolerated.

Abstract
Abstract
Background: Breast cancer related lymphedema (BCRL) represents a common treatment associated complication following surgery, radiation and/or chemotherapy. Increasing data has demonstrated the ability of new diagnostic modalities to detect BCRL in the subclinical phase of the process allowing for early intervention.
Trial Design: This 2-group stratified randomized clinical trial evaluates the effectiveness of bioimpedance spectroscopy (BIS) for early detection and prevention of BCRL compared to tape measurement (TM). Baseline assessments are made pre-operatively. Two-months post-op, patients are censored out if they have developed any of the exclusion conditions, did not have a mastectomy, axillary dissection, >6 sentinel nodes removed, radiation therapy, or taxane. Remaining patients are randomized within site to either BIS or TM; monitored at 3 to 6-month intervals up to 36-months post-op for a change over baseline specified to trigger a compression sleeve & gauntlet intervention. Cohort trigger thresholds are change of ≥10 L-Dex units or 5 to <10% volume. If the intervention is triggered, measurements by the other method are taken before initiating the 4-week intervention. Post intervention, patients are monitored only with TM. Volume change of ≥10% results in study removal and physician referral. At the 2 study endpoints (36 month visit or volume change of ≥10%) measurements are taken with each method.
Eligibility Criteria: Inclusion criteria: ≥ 18 with histologically confirmed stage I-III breast cancer (BC) or DCIS with planned surgery. Exclusion criteria include history of BC therapy or lymphedema.
Specific Aims: The primary hypothesis is that subclinical detection of BCRL with BIS and early intervention will reduce the rate of lymphedema progression (as measured by referral to complex decongestive physiotherapy) compared to TM. Secondary outcomes include BCRL risk factors, quality of life, and time to treatment.
Statistical Methods: Sample size and powering were based on the hypothesis that BIS would reduce progression rate by 20%. A rate of 50% progression in the TM group was used as the standard. 1100 patients will be enrolled to result in randomized groups of 100 (Total N=200) Statistics include relative risks with respective bootstrapped 95% C.I. and Cochran-Mantel-Haenszel tests.
Present Accrual and Target Accrual: Overall, the study target or expected enrollment as of the end of March 31, 2016 was 690 participants, 534 were actually enrolled (actual accrual 77% of target). Accrual at the study sites ranged from 15 to 104% of target.

Abstract
Studies of schizophrenia at drug-naive state and on antipsychotic medication have reported a number of regions of gray-matter (GM) abnormalities but the reports have been inconsistent. The aim of this study was to conduct multimodal meta-analysis to compare the cross-sectional voxel-based morphometry studies of brain GM in antipsychotic-naive first-episode schizophrenia (AN-FES) and those with antipsychotic treatment within 1 year (AT-FES) to determine the similarities and differences in these groups. We conducted two separate meta-analyses containing 24 studies with a sample size of 801 patients and 957 healthy controls. A multimodal meta-analysis method was used to compare the findings between AN-FES and AT-FES. Meta-regression analyses were done to determine the influence of different variables including age, duration of illness, and positive and negative symptom scores. Finally, jack-knife analyses were done to test the robustness of the results. AN-FES and AT-FES showed common patterns of GM abnormalities in frontal (gyrus rectus), superior temporal, left hippocampal and insular cortex. GM in the left supramarginal gyrus and left middle temporal gyrus were found to be increased in AN-FES but decreased in AT-FES, whereas left median cingulate/paracingulate gyri and right hippocampus GM was decreased in AN-FES but increased in AT-FES. Findings suggest that both AN-FES and AT-FES share frontal, temporal and insular regions as common anatomical regions to be affected indicating these to be the primary regions of GM abnormalities in both groups.

Abstract
The present study, evaluates the antioxidative potential of two synbiotic dairy products viz. synbiotic lassi with honey and whey based synbiotic drink with inulin and orange juice, along with their physicochemical and microbiological activity during storage period. Antioxidative potential of raw ingredients and probiotic cultures used to prepare synbiotic products was also evaluated. Synbiotic lassi with honey was prepared using Streptococcus thermophilus MTCC 5460 (MD2) and Lactobacillus helveticus MTCC 5463 (V3) as probiotics and honey as prebiotic. For preparation of whey based synbiotic drink, Lactobacillus helveticus MTCC 5463 and inulin were used as probiotic and prebiotic, respectively and orange juice was also incorporated. Titratable acidity and pH of both synbiotic products followed a similar pattern of increase or decrease during storage. Furthermore, no major changes were observed in viability of probiotic cultures under storage conditions adapted. The hydroxyl radical scavenging activity of synbiotic lassi with honey was found to significantly decrease from 107.76 to 79.41 % at the end of storage whereas, the activity of whey based synbiotic drink was 100.32 % which declined sharply to 79.21 % on 7th day but further increased to 102.59 % on 14th day. The DPPH (α, α-Diphenyl-β-Picrylhydrazyl) radical scavenging activity of freshly prepared synbiotic lassi with honey was 28.43 % which decreased to 23.03 % on 7th day while for whey based synbiotic drink decreased from 26.85 % (0 day) to 17.12 % (7th day) and continued to decline. Moreover, probiotic strains used for synbiotic preparation also demonstrated good antioxidative activity.

Abstract
Probiotics are known for their health beneficial effects and are established as dietary adjuncts. Probiotics have been known for many beneficial health effects. In this view, there is interest to find the potential probiotic strains that can exhibit antioxidant properties along with health benefits. In vitro and in vivo studies indicate that probiotics exhibit antioxidant potential. In this view, consumption of probiotics alone or foods supplemented with probiotics may reduce oxidative damage, free radical scavenging rate, and modification in activity of crucial antioxidative enzymes in human cells. Incorporation of probiotics in foods can provide a good strategy to supply dietary antioxidants, but more studies are needed to standardize methods and evaluate antioxidant properties of probiotics before they can be recommended for antioxidant potential. In this paper, the literature related to known antioxidant potential of probiotics and proposing future perspectives to conduct such studies has been reviewed.

Abstract
We performed a multi-institutional analysis to evaluate the ability of bioimpedance spectroscopy (BIS) to capture the impact of lymphedema treatment compared with observation alone in the management of breast cancer related lymphedema (BCRL). We utilized a retrospective review of 50 patients with breast cancer who were evaluated with BIS at baseline and following loco-regional treatment. An analysis was performed comparing changes in L-Dex scores for those patients undergoing treatment for BCRL (n=13) versus those not undergoing intervention (n=37). A second (subset) analysis was also performed on all patients with elevated L-Dex scores compared to baseline prior to undergoing loco-regional treatment (n=32). When comparing the cohort treated for BCRL to those not treated, L-Dex scores were significantly reduced (-4.3 v. 0.1, p=0.005) in the period following intervention (for treated patients). For the subset of patients with elevated L-Dex scores postoperation, the change in L-Dex score following BCRL treatment was significantly reduced (-5.8 v. 0.1, p=0.001) compared with the group observed that had elevated postsurgical L-Dex scores. In this analysis, BIS was able to detect early onset lymphedema and subsequently significant changes (reductions) in L-Dex scores directly related to intervention for BCRL compared with observation alone.
