Triple-Negative versus Non–Triple-Negative Breast Cancers in High-Risk Women: Phenotype Features and Survival from the HIBCRIT-1 MRI-Including Screening Study

Purpose: To compare phenotype features and survival of triple-negative breast cancers (TNBC) versus non-TNBCs detected during a multimodal annual screening of high-risk women. Experimental Design: Analysis of data from asymptomatic high-risk women diagnosed with invasive breast cancer during the HIBCRIT-1 study with median 9.7-year follow-up. Results: Of 501 enrolled women with BRCA1/2 mutation or strong family history (SFH), 44 were diagnosed with invasive breast cancers: 20 BRCA1 (45%), 9 BRCA2 (21%), 15 SFH (34%). Magnetic resonance imaging (MRI) sensitivity (90%) outperformed that of mammography (43%, P < 0.001) and ultrasonography (61%, P = 0.004). The 44 cases (41 screen-detected; 3 BRCA1-associated interval TNBCs) comprised 14 TNBCs (32%) and 30 non-TNBCs (68%), without significant differences for age at diagnosis, menopausal status, prophylactic oophorectomy, or previous breast cancer. Of 14 TNBC patients, 11 (79%) were BRCA1; of the 20 BRCA1 patients, 11 (55%) had TNBC; and of 15 SFH patients, 14 (93%) had non-TNBCs (P = 0.007). Invasive ductal carcinomas (IDC) were 86% for TNBCs versus 43% for non-TNBCs (P = 0.010), G3 IDCs 71% versus 23% (P = 0.006), size 16 ± 5 mm versus 12 ± 6 mm (P = 0.007). TNBC patients had more frequent ipsilateral mastectomy (79% vs. 43% for non-TNBCs, P = 0.050), contralateral prophylactic mastectomy (43% vs. 10%, P = 0.019), and adjuvant chemotherapy (100% vs. 44%, P < 0.001). The 5-year overall survival was 86% ± 9% for TNBCs versus 93% ± 5% (P = 0.946) for non-TNBCs; 5-year disease-free survival was 77% ± 12% versus 76% ± 8% (P = 0.216). Conclusions: In high-risk women, by combining an MRI-including annual screening with adequate treatment, the usual reported gap in outcome between TNBCs and non-TNBCs could be reduced.

Cryptosporidiosis in patients with diarrhea and chronic liver diseases.

INTRODUCTION The aim of this study was to evaluate the epidemiology and clinical significance of Cryptosporidium in patients with diarrhea and chronic liver diseases. METHODOLOGY The study included 150 patients with chronic liver diseases and diarrhea, and 50 subjects with diarrhea as a control group. Stool samples were screened for the presence of Cryptosporidium by microscopic examination after modified Ziehl-Neelsen staining and detection of Cryptosporidium coproantigen by enzyme-linked immunosorbent assay (ELISA). RESULTS The prevalence of Cryptosporidium infection in patients with chronic liver diseases was 30% (45/150) versus 14% (7/50) in controls. Cryptosporidium infection increased with the progression of chronic liver diseases from Child-Pugh class A to Child-Pugh class C (p< 0.001) and from model for end-stage liver disease (MELD) score ≤ 9 to MELD score > 9 (p< 0.031). Nine patients in Child-Pugh class C with diarrhea associated with Cryptosporidium infection developed hepatic encephalopathy, and only diarrhea was identified as a precipitating factor for hepatic encephalopathy. CONCLUSIONS Cryptosporidium is one of the important causes of diarrhea in patients with chronic liver diseases. The infection significantly increased with the progression of chronic liver diseases. In patients with advanced chronic liver diseases, Cryptosporidium infection may be a precipitating factor of hepatic encephalopathy.
Selective loss of sarcolemmal nitric oxide synthase in Becker muscular dystrophy

Becker muscular dystrophy is an X-linked disease due to mutations of the dystrophin gene. We now show that neuronal-type nitric oxide synthase (nNOS), an identified enzyme in the dystrophin complex, is uniquely absent from skeletal muscle plasma membrane in many human Becker patients and in mouse models of dystrophinopathy. An NH2- terminal domain of nNOS directly interacts with alpha 1-syntrophin but not with other proteins in the dystrophin complex analyzed. However, nNOS does not associate with alpha 1-syntrophin on the sarcolemma in transgenic mdx mice expressing truncated dystrophin proteins. This suggests a ternary interaction of nNOS, alpha 1-syntrophin, and the central domain of dystrophin in vivo, a conclusion supported by developmental studies in muscle. These data indicate that proper assembly of the dystrophin complex is dependent upon the structure of the central rodlike domain and have implications for the design of dystrophin-containing vectors for gene therapy.
A search for sex differences in response to analgesia.

BACKGROUND It is generally accepted that males and females respond differently to painful conditions. With few exceptions, according to the published literature, females demonstrate a lower pain threshold and a lower tolerance of painful stimuli. There is some support in the literature that females experience greater analgesic efficacy than do males after the administration of narcotic analgesics. We compared the analgesic response of females and males to ibuprofen in a post-third-molar extraction dental pain model. METHODS We performed a meta-analysis of 314 subjects included in the ibuprofen treatment arm of 7 double-blind, post-third-molar extraction dental pain (moderate to severe) studies, which were submitted to the agency electronically. The inclusion and exclusion criteria were practically identical in all studies. Pain relief and pain intensity measurements used the same metrics in all studies and were recorded just before and at least at 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0, and 6. 0 hours after drug administration. RESULTS The study included 195 female subjects and 119 male subjects (mean age, 21 years). Other than requiring dental extractions, the subjects were all healthy. Postoperative baseline pain was greater in females than in males to a statistically significant degree (P =.006). Both pain intensity and pain relief scores demonstrated the well-established analgesic effect of ibuprofen in the pooled data set as well as in all the individual studies. Moreover, the mean pain intensity and pain relief scores over time for the female and male treatment groups were not noticeably different at any time point after drug administration, with no imputation for missing values. Analysis of the data using the "baseline observation carried-forward" technique for remedicated subjects (the technique recommended by the Food and Drug Administration for efficacy analysis of acute analgesic medications) produced the same results, which were confirmed by analysis of variance and t tests at each time point of the study. CONCLUSIONS Our results demonstrated no sex effect on the analgesic response to ibuprofen. These results were obtained under the post-third-molar extraction setting, in which the least possible confounding factors are present. To fully establish the generality of this phenomenon, studies should be carried out in other pain models and using analgesic medications with different mechanisms of action.

Targeting the Notch Ligand Jagged1 in Both Tumor Cells and Stroma in Ovarian Cancer

Purpose: Jagged1, a Notch ligand, is expressed on both tumor epithelial and endothelial cells and therefore may be amenable to dual targeting of the tumor stroma and malignant cell compartments of the tumor microenvironment. Experimental Design: We describe in vitro effects of targeting of Jagged1 on ovarian cancer cells and in vivo effects of independent targeting of stromal and malignant cell Jagged1 using species-specific human or murine siRNA constructs incorporated into chitosan nanoparticles and delivered intravenously in an orthotopic mouse model. Results: Jagged1 expression was prominent in SKOV3ip1 and IGROV-AF1, and significantly overexpressed in SKOV3TRip2, a taxane-resistant SKOV3 subclone. Jagged1 silencing with siRNA decreased cell viability and reversed taxane chemoresistance. In two different orthotopic ovarian cancer models, treatment with anti-human Jagged1 siRNA-CH reduced growth by 54.4% to 58.3% and with anti-murine Jagged1 siRNA-CH reduced growth by 41.7% to 48.8%. The combination of both species-specific constructs reduced tumor weight by 87.5% to 93.1% and sensitized SKOV3TRip2 tumors to docetaxel in vivo. Tumors showed reduced microvessel density with anti-murine Jagged1 constructs and decreased proliferation with anti-human Jagged1 siRNAs-CH. In addition, we show that Jagged1 downregulation does not sensitize cells to taxanes through a reduction in MDR1 expression, but at least in part by cross-talk with the GLI2 mediator of the Hedgehog pathway. Conclusions: Jagged1 plays dual roles in cancer progression through an angiogenic function in tumor endothelial cells and through proliferation and chemoresistance in tumor cells. Dual inhibition represents an attractive therapeutic strategy for ovarian and potentially other malignancies. Clin Cancer Res; 17(17); 5674–85. ©2011 AACR.
Recognition and Exploitation of Contextual CLues via Incremental Meta-Learning

The disclosure of this specification illustrates a GAP FILLER, designed to be easily and quickly removed from the gap between poured concrete sections, after the concrete sets. The individual plastic-foam slats, held together and attached to each other, are packaged in a watertight polyethylene bag, and are positioned against an existng concrete wall, ready to receive the second concrete pour. The zip-out filler will form the expansion joint between the two concrete pours. Removal of the filler is easily accomplished because of the inter-connected slats.
Accelerating Biological Sequence Alignment Algorithm on GPU with CUDA

In this paper, we have used Compute Unified Device Architecture (CUDA) GPU to accelerate pair wise sequence alignment using the Smith-Waterman (SW) algorithm. Smith-Waterman(SW) is by far the best algorithm for its accuracy in similarity scoring. But the executing time of this algorithm is too long in sequence alignment. So we describe a multi-threaded parallel design and implementation of the Smith-Waterman (SW) on CUDA to reduce execution time. And according the architecure of CUDA, we have divided the computation of a whole pair wise sequence alignment scoring matrix into multiple sub-matrices, using 32 threads to process on submatrice, more over we optimized memory distribution scheme, and used reduction to find the maximum element of the alignment scoring matrix. We experiment the algorimthm on GeForce 9600 GT, connet to Windows xp 64-bit system. The results show this mplementation achieves more better performance than the other parallel implementation on the Graphics Processing Unit.
Validity and Reproducibility of a Revised Semi-quantitative Food Frequency Questionnaire (SQFFQ) for Women of Age-group 12-44 Years in Chengdu

ABSTRACT To find a credible nutritional screening tool for evaluating relationship between nutritional status and diseases in Chengdu female residents, the reliability and validity of a revised semi-quantitative food frequency questionnaire (SQFFQ) were tested. The validity was assessed by comparing the SQFFQ with the ‘standard’ method of 3 days’ dietary recall, and the reliability was assessed by comparing the first SQFFQ with the second SQFFQ at 4 weeks interval. Correlation analysis showed that, for reliability, the average correlation coefficient (CC) of 22 kinds of nutrients was 0.66 and reduced to 0.60 after adjusting for energy; the average of intra-class correlation coefficients (ICC) was 0.65. For validity, the average CC was 0.35 and remained stable after adjusting for CC of energy or nutrients. Validity of 17 nutrients in SQFFQ survey had correlation with result of 3 days’ dietary recall. The results showed that the revised SQFFQ can be used for investigating the role of nutrients in development of disease in Chengdu female residents.
Effects of Plasma Transfusion on Perioperative Bleeding Complications: A Machine Learning Approach

Perioperative bleeding (PB) is associated with increased patient morbidity and mortality, and results in substantial health care resource utilization. To assess bleeding risk, a routine practice in most centers is to use indicators such as elevated values of the International Normalized Ratio (INR). For patients with elevated INR, the routine therapy option is plasma transfusion. However, the predictive accuracy of INR and the value of plasma transfusion still remains unclear. Accurate methods are therefore needed to identify early the patients with increased risk of bleeding. The goal of this work is to apply advanced machine learning methods to study the relationship between preoperative plasma transfusion (PPT) and PB in patients with elevated INR undergoing noncardiac surgery. The problem is cast under the framework of causal inference where robust meaningful measures to quantify the effect of PPT on PB are estimated. Results show that both machine learning and standard statistical methods generally agree that PPT negatively impacts PB and other important patient outcomes. However, machine learning methods show significant results, and machine learning boosting methods are found to make less errors in predicting PB.

Identification of Cytochrome P450 Oxidoreductase Gene Variants That Are Significantly Associated with the Interindividual Variations in Warfarin Maintenance Dose

Cytochrome P450 oxidoreductase (POR) is required for drug metabolism by all microsomal cytochrome P450 enzymes. The aim of this study was to investigate whether any of the common single nucleotide polymorphisms (SNPs) in the POR gene and its flanking intergenic sequences correlate with interindividual variations in the warfarin maintenance dose (which is determined partly by rates of warfarin metabolism) in patients undergoing anticoagulation therapy. Warfarin dose and patients' demographic and clinical information were collected from 124 patients, who had attained a stable warfarin dose while receiving treatment at the Stratton VA Medical Center. Genomic DNAs were isolated from blood samples and were genotyped for 15 SNPs (including 10 SNPs on the POR gene). Association analysis was performed on 122 male patients by linear regression. Simple regression analysis revealed that vitamin K epoxide reductase complex subunit 1 (VKORC1) −1639A>G, CYP2C9*2, CYP2C9*3, age, and chronic aspirin therapy were significantly associated with warfarin dose. In contrast, multiple regression analysis revealed that, in addition to several known factors contributing to the variations in warfarin maintenance dose (VKORC1 −1639A>G, CYP2C9*2, CYP2C9*3, CYP4F2 rs2108622, and chronic aspirin therapy), three common POR SNPs (−173C>A, −208C>T, and rs2868177) were also significantly associated with variations in warfarin maintenance dose. These results indicate, for the first time, that three common SNPs in the POR gene may contribute to the interindividual variability in warfarin maintenance dose. Further studies on functional characterization of the POR SNPs identified, including their impact on the in vivo metabolism of additional drugs, are needed.
Bevacizumab in ovarian cancer: A critical review of phase III studies

Bevacizumab (BV) is a humanized monoclonal antibody targeting vascular endothelial growth factor and it is the first molecular-targeted agent to be used for the treatment of ovarian cancer (OC). Randomized Phase III trials evaluated the combination of BV plus standard chemotherapy for first-line treatment of advanced OC and for platinum-sensitive and platinum-resistant recurrent OC. These trials reported a statistically significant improvement in progression-free survival but not in overall survival. Furthermore, BV effectively improved the quality of life with regard to abdominal symptoms in recurrent OC patients. Bevacizumab is associated with adverse events such as hypertension, bleeding, thromboembolism, proteinuria, delayed wound healing, and gastrointestinal events. However, most of these events can be adequately managed. This review describes the latest evidence for BV treatment of OC and selection of patients for personalized treatment.
Association of Frontline Worker-Provided Services with Change in Block-Level Complementary Feeding Indicators: An Ecological Analysis from Bihar, India

Background Insufficiencies in complementary feeding put infants and young children at increased risk of undernutrition. Till now, most Indian studies have looked at the individual level determinants of complementary feeding practices. We aimed to evaluate the association of frontline worker (FLW) provided nutritional counselling services, with change in community level indicators of complementary feeding practices among 9–11 month old children over time. Methods The study data was obtained from five rounds of ‘Lot Quality Assurance Sampling’ survey in eight districts of Bihar, an impoverished Indian state. The surveys were conducted as evaluation exercises for the ‘Integrated Family Health Initiative (IFHI)’–a multi-faceted program aimed at improving the maternal and child health outcomes in Bihar. The main outcome indicators were—current breastfeeding, age-appropriate minimum frequency of semi-solid food, age-appropriate minimum quantity of semi-solid food, initiation of complementary feeding at the right age, and dietary diversity. Repeated measures analysis was performed to determine the association of changes in the outcome indicators with coverage of FLW-provided counselling services. Results Visits by FLW, advices on age-appropriate frequency and handwashing were significant predictors of receiving age-appropriate frequency of feeding. The determinants of receiving age-appropriate quantity were—advices on age appropriate frequency and advices on handwashing. Receiving food support from AWC and FLW visits were significantly associated with initiating complementary feeding at the right age. Conclusions The present study identified the critical elements among the different types of FLW-provided services. The study findings, from an economically and socially underdeveloped region of India, would inform the relevant programs about the nutritional counselling services that need to be emphasized upon for reducing the burden of childhood malnutrition.

We also report on a new alignment model and a new training algorithm based on alternating maximization of likelihood with minimization of error rate.
What Motivates a Student to Participate in the Electronic Discussion Forum: A Survey Study of Students' Participation Intention

Electronic discussion forum has increasingly being utilized to complement the conventional ways of teaching by encouraging the students to take a more proactive approach towards learning. Despite the widespread application, antecedent evidence indicates that the forum may not be utilized to its full potential due to lower than expected student participation. Furthermore, little research has been conducted to understand the determinants of learners’ intention towards active participation from the behavioral perspective. With reference to the Theory of Planned Behavior (TPB), this research, seeks to identify and examine the factors influencing the student’s intention to participate in electronic discussion forum. A conceptual model depicts the causal relationships of outcome expectancy, subjective norms and perceived behavioral control on intention formation. Moderating variables of perceived importance of learning and conformity motivation are also studied. A survey is conducted. Results and implications are discussed.
Polybrominated Diphenyl Ethers (PBDEs) in Breast Milk and Neuropsychological Development in Infants

Background: There is increasing interest in the potential effects of polybrominated diphenyl ethers (PBDEs) on children’s neuropsychological development, but only a few small studies have evaluated such effects. Objectives: Our goal was to examine the association between PBDE concentrations in colostrum and infant neuropsychological development and to assess the influence of other persistent organic pollutants (POPs) on such association. Methods: We measured concentrations of PBDEs and other POPs in colostrum samples of 290 women recruited in a Spanish birth cohort. We tested children for mental and psychomotor development with the Bayley Scales of Infant Development at 12–18 months of age. We analyzed the sum of the seven most common PBDE congeners (BDEs 47, 99, 100, 153, 154, 183, 209) and each congener separately. Results: Increasing Σ7PBDEs concentrations showed an association of borderline statistical significance with decreasing mental development scores (β per log ng/g lipid = –2.25; 95% CI: –4.75, 0.26). BDE-209, the congener present in highest concentrations, appeared to be the main congener responsible for this association (β = –2.40, 95% CI: –4.79, –0.01). There was little evidence for an association with psychomotor development. After adjustment for other POPs, the BDE-209 association with mental development score became slightly weaker (β = –2.10, 95% CI: –4.66, 0.46). Conclusions: Our findings suggest an association between increasing PBDE concentrations in colostrum and a worse infant mental development, particularly for BDE-209, but require confirmation in larger studies. The association, if causal, may be due to unmeasured BDE-209 metabolites, including OH-PBDEs (hydroxylated PBDEs), which are more toxic, more stable, and more likely to cross the placenta and to easily reach the brain than BDE-209.
IITPatna: Supervised Approach for Sentiment Analysis in Twitter

In this paper we report our works for SemEval-2014 Sentiment Analysis in Twitter evaluation challenge. This is the first time we attempt for this task, and our submissions are based on supervised machine learning algorithm. We use Support Vector Machine for both the tasks, viz. contextual polarity disambiguation and message polarity classification. We identify and implement a small set of features for each the tasks, and did not make use of any external resources and/or tools. The systems are tuned on the development sets and finally blind evaluation is performed on the respective test set, which consists of the datasets of five different domains. Our submission for the first task shows the F-score values of 76.3%, 77.04%, 70.91%, 72.25% and 66.32% for LiveJournal2014, SMS2013, Twitter2013, Twitter2014 and Twitter2014Sarcasm datasets, respectively. The system developed for the second task yields the F-score values of 54.68%, 40.56%, 50.32%, 48.22% and 36.73%, respectively for the five different test datasets.
