Treatment Patterns and Mortality Risk among Elderly Patients with Metastatic Triple Negative Breast Cancer in the United States: An Observational Cohort Study Using SEER-Medicare Data  [PDF]
Sacha Satram-Hoang, Preeti Bajaj, Alisha Stein, Patricia Cortazar, Faiyaz Momin, Carolina Reyes
Journal of Cancer Therapy (JCT) , 2019, DOI: 10.4236/jct.2019.102009
Abstract: Purpose: Triple negative breast cancer is more aggressive than other breast cancer subtypes and accounts for up to 20% of all breast cancers. Despite the poorer prognosis, there are no approved targeted treatments available and chemotherapy remains the only choice. We examined treatment patterns and outcomes among elderly metastatic triple-negative breast cancer (mTNBC) patients in routine clinical practice. Methods: Patients were identified from the linked SEER-Medicare database between 1/1/2001 and 12/31/2013 and included de novo Stage IV (n = 776) and patients with distant metastasis followed an initial diagnosis of Stage I - III disease (n = 1851). Kaplan-Meier analyses and time-varying Cox proportional hazards regression were used to assess overall survival (OS). Results: The mean age at metastatic diagnosis was 77.6 years and 1259 (48%) patients received chemotherapy. Compared to <70 year olds, ≥70 year olds had worse
Visuomotor Learning Enhanced by Augmenting Instantaneous Trajectory Error Feedback during Reaching
James L. Patton, Yejun John Wei, Preeti Bajaj, Robert A. Scheidt
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0046466
Abstract: We studied reach adaptation to a 30° visuomotor rotation to determine whether augmented error feedback can promote faster and more complete motor learning. Four groups of healthy adults reached with their unseen arm to visual targets surrounding a central starting point. A manipulandum tracked hand motion and projected a cursor onto a display immediately above the horizontal plane of movement. For one group, deviations from the ideal movement were amplified with a gain of 2 whereas another group experienced a gain of 3.1. The third group experienced an offset equal to the average error seen in the initial perturbations, while a fourth group served as controls. Learning in the gain 2 and offset groups was nearly twice as fast as controls. Moreover, the offset group averaged more reduction in error. Such error augmentation techniques may be useful for training novel visuomotor transformations as required of robotic teleoperators or in movement rehabilitation of the neurologically impaired.
Simulating the Effect of Social Network Structure on Workflow Efficiency Performance  [PDF]
Akhilesh Bajaj, Sandip Sen
Social Networking (SN) , 2014, DOI: 10.4236/sn.2014.31004
Abstract:

The effect of social network structure on team performance is difficult to investigate using standard field observational studies. This is because social network structure is an endogeneous variable, in that prior team performance can influence the values of structural measures such as centrality and connectedness. In this work we propose a novel simulation model based on agent-based modeling that allows social network structure to be treated as an exogeneous variable but still be allowed to evolve over time. The simulation model consists of experiments with multiple runs in each experiment. The social network amongst the agents is allowed to evolve between runs based on past performance. However, within each run, the social network is treated as an exogenous variable where it directly affects workflow performance. The simulation model we describe has several inputs and parameters that increase its validity, including a realistic workflow management depiction and real-world cognitive strategies by the agents.

Tessier 30 Facial Cleft Associated with Complete Duplication of Tongue: A Rare Entity  [PDF]
Jayanto Tapadar, Preeti Tiwari
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2015, DOI: 10.4236/ijohns.2015.42029
Abstract: Background: Median cleft of mandible and lower lip is a rare anomaly [1]. Only a few cases have been reported in literature with different variations till now. Herein we report a patient with Tessier 30 cleft associated with complete duplication of tongue. Aim: We herein report this rare variant as it posed special challenges for its management by virtue of its uniqueness, late presentation and limited affordability of patient for standard treatment. Case Report: A 12 years old female reported to us with a chief complaint of a midline gap in the lower lip and mandible since birth. On examination under anaesthesia, we found that tongue was not bifid. There was complete duplication of the tongue. The case was planned for staged repair of the defect. In the same sitting, a repair of the soft tissues in the midline was performed. Conclusion: There are no specific guidelines in literature for management of such cases. This makes all these cases worth for reporting in order to guide treating surgeons.
Coupled Fixed Point for (α, Ψ)-Contractive in Partially Ordered Metric Spaces Using Compatible Mappings  [PDF]
  Preeti, Sanjay Kumar
Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.68130
Abstract: In this paper, first we introduce notions of (α, Ψ)-contractive and (α)-admissible for a pair of map and prove a coupled coincidence point theorem for compatible mappings using these notions. Our work extends and generalizes the results of Mursaleen et al. [1]. At the end, we will provide an example in support of our result.
Thermostable alkaline protease production from Bacillus pumilus D-6 by using agro-residues as substrates  [PDF]
Bijender Kumar Bajaj, Gaytri Jamwal
Advances in Enzyme Research (AER) , 2013, DOI: 10.4236/aer.2013.12003
Abstract: Proteases due to their wide range of applications in biotechnological processes have been the  focus of intense research for many decades. However, from industrial application view point most of the available proteases lack desired properties; therefore, search for better and efficient thermostable alkaline proteases are always on. Bacillus pumilus D-6, isolated from dairy plant soil sample, in the current study produced protease which showed activity and stability at high alkaline pH (8 - 12) and high temperatures (70C- 100C). Enzyme activity remained unfazed even in presence of inhibitors like Pb2+and Hg2+which are considered universal inhibitors of enzyme activity. Besides, the organism successfully utilized crude agriculture based substrates as carbon and nitrogen source and produced substantial enzyme titre.



Exhaled Breath Condensates as a Source for Biomarkers for Characterization of Inflammatory Lung Diseases  [PDF]
Puneet Bajaj, Faoud T. Ishmael
Journal of Analytical Sciences, Methods and Instrumentation (JASMI) , 2013, DOI: 10.4236/jasmi.2013.31004
Abstract:

Inflammatory lung diseases such as asthma and chronic obstructive pulmonary disease are common and difficult to diagnose and characterize. This is due in large part to difficulty in obtaining samples directly from the inflamed lung. The collection of lung secretions by traditional methods including bronchoalveolar lavage and induced sputum collection are limited by their invasive nature. Exhaled breath condensate (EBC) is a simple and non-invasive technique of collecting fluid samples, which are representative of airway lining fluid. Advances in collection methods and evolving molecular techniques have led to development of more sensitive assays for existing biomarkers and identification of new biomarkers, which can be potentially useful in monitoring lung inflammation. In this review, we present the current understanding of various biomarkers including small molecules (H2O2, pH and nitric oxide related biomarkers), lipid mediators (8-isprostane, leukotrienes and prostaglandins), small proteins (cytokines and chemokines) and nucleic acids (DNA and microRNAs). We also discuss the differential profile of biomarkers in recognizing different patterns of lung inflammation. As the sensitivity of methods of EBC improves, this biofluid will play an increasing role in diagnosis and monitoring of lung diseases.
