Protecting New York City from Homegrown Terrorism: The City's Role in Radicalization and Counter-Radicalization

Over the past decade, the city of New York has come to grips with the specter of global terrorism. Governments, no matter how large or small, are responsible for protecting their people, and the city of New York is of no exception. How the city chooses to protect its people and assets through law enforcement and other measures is a subject that has received little attention, due to the mentality of 'doing now' and asking questions 'later'. The role of the city in addressing the most recent threat, homegrown terrorists, is one that is central to the struggle against terrorism and violence. In order to address this role, it is prudent to understand how individuals become radicalized and what actions governments can take to counter this behavior

Chromosomal abnormalities and Y chromosome microdeletions in infertile men with varicocele and idiopathic infertility of South Indian origin

Various factors cause spermatogenesis arrest in men and, in a large number of cases, the underlying reason still remains unknown. Little attention is paid to determining the genetic defects of varicocele-related infertility. The objective of our present study was to investigate the chromosomal abnormalities and Y chromosome microdeletions in infertile men of South Indian origin with varicocele and idiopathic infertility. Metaphase chromosomes of 251 infertile men with varicocele and unexplained infertility were analyzed using Giemsa-Trypsin-Giemsa (GTG) banding and fluorescence in situ hybridization (FISH). The microdeletions in 6 genes and 18 sequence-tagged-sites (STS) in the Yq region were screened using polymerase chain reaction (PCR) techniques. Out of 251 infertile men, 57 (22.7%) men were with varicocele, of which 8.77% were azoospermic, 26.31% were severely oligozoospermic, 21.05% were mildly oligozoospermic, and 43.85% were oligoasthenoteratozoospermic (OAT), and 194 (77.29%), with idiopathic infertility, of which 51% were azoospermic, 13.40% were severely oligozoospermic, 19.07% were mildly oligozoospermic, and 16.4% were with OAT. Genetic defects were observed in 38 (15.13%) infertile individuals, including 14 (24.56%) men with varicocele and 24 (12.37%) men with idiopathic infertility. The frequencies of chromosomal defects in varicocele and idiopathic infertility were 19.3% and 8.76%, respectively, whereas Y chromosome microdeletions were 5.26% and 3.60%, respectively. Overall rate of incidence of chromosomal anomalies and microdeletions in 251 infertile men were 11.5% and 3.98%, respectively, indicating a very significant higher association of genetic defects with varicocele than idiopathic male infertility. Our data also demonstrate that, among infertile men with varicocele, severely oligozoospermic and OAT men with varicocele have higher incidences of genetic defects than mildly oligozoospermic and azoospermic men

Organizational metrics of interchromatin speckle factor domains: integrative classifier for stem cell adhesion & lineage signaling.

Stem cell fates on biomaterials are influenced by the complex confluence of microenvironmental cues emanating from soluble growth factors, cell-to-cell contacts, and biomaterial properties. Cell-microenvironment interactions influence the cell fate by initiating a series of outside-in signaling events that traverse from the focal adhesions to the nucleus via the cytoskeleton and modulate the sub-nuclear protein organization and gene expression. Here, we report a novel imaging-based framework that highlights the spatial organization of sub-nuclear proteins, specifically the splicing factor SC-35 in the nucleoplasm, as an integrative marker to distinguish between minute differences of stem cell lineage pathways in response to stimulatory soluble factors, surface topologies, and microscale topographies. This framework involves the high resolution image acquisition of SC-35 domains and imaging-based feature extraction to obtain quantitative nuclear metrics in tandem with machine learning approaches to generate a predictive cell state classification model. The acquired SC-35 metrics led to \u3e 90% correct classification of emergent human mesenchymal stem cell (hMSC) phenotypes in populations of hMSCs exposed for merely 3 days to basal, adipogenic, or osteogenic soluble cues, as well as varying levels of dexamethasone-induced alkaline phosphatase (ALP) expression. Early osteogenic cellular responses across a series of surface patterns, fibrous scaffolds, and micropillars were also detected and classified using this imaging-based methodology. Complex cell states resulting from inhibition of RhoGTPase, β-catenin, and FAK could be classified with \u3e 90% sensitivity on the basis of differences in the SC-35 organizational metrics. This indicates that SC-35 organization is sensitively impacted by adhesion-related signaling molecules that regulate osteogenic differentiation. Our results show that diverse microenvironment cues affect different attributes of the SC-35 organizational metrics and lead to distinct emergent organizational patterns. Taken together, these studies demonstrate that the early organization of SC-35 domains could serve as a “fingerprint” of the intracellular mechanotransductive signaling that governs growth factor- and topography-responsive stem cell states

Epworth Sleepiness Scale- a novel tool to assess somnolence syndrome in patients receiving radiotherapy to the brain

Purpose: Radiation to brain causes early, early-delayed, and delayed side effects. There is paucity of literature regarding early-delayed effects like somnolence syndrome. Existing studies use general symptom assessment and visual analog scales. Epworth Sleepiness Scale (ESS) is a time tested tool to assess daytime sleepiness in various conditions. In this study, the ESS has been used to determine the occurrence of somnolence in patients receiving cranial radiotherapy for primary and metastatic brain tumors. Thus the ESS has been used in a novel setting in our study. The ESS is a simple to administer questionnaire and may be useful in grading the severity of somnolence. To our knowledge, this is the second study to determine post radiation somnolence using ESS. Methods: This prospective study was conducted in 23 patients with primary and metastatic brain tumor. Patient demographics and tumor type and grade was noted. Those with Karnofsky Performance Scale (KPS) less than 70 and with pre-existing sleep disorders were excluded. Radiotherapy regimen included palliative whole brain radiation for brain metastases and conformal adjuvant radiotherapy for primary brain tumors as per standard guidelines. All subjects included were administered ESS at baseline and weekly thereafter during and for 6 weeks after radiation. Results: All 23 patients (median age 50 years) completed the planned questionnaires until 6 weeks post radiation. Twenty (87%) patients had primary brain tumors whereas three (13%) patients had metastatic lesions in brain. Of the 23 patients, 14 patients (60.86%) had abnormal or increased daytime sleepiness; of which 3 had ESS scores greater than 16. Conclusion: Somnolence was noted in 60.86% of the patients, which is in accordance with existing literature. Epworth sleepiness scale is an effective tool to detect and quantify somnolence, However, it does not consider other symptoms of somnolence syndrome and hence should be combined with visual analog scale to get complete information

A case of endometrial carcinoma with age related hyperkyphosis treated with definitive radiotherapy

This report describes a simple brachytherapy procedure in a patient with endometrial cancer with age related hyperkyphosis.  Sixty-eight year-old postmenopausal woman with age related hyperkyphosis presented with endometrial carcinoma, and the patient was not operated on due to associated pelvic deformity. The patient received whole pelvic radiation followed by uterovaginal brachytherapy. Patient was supported with soft pillows to support her exaggerated anterior concavity during brachytherapy procedure and execution. The brachytherapy dose was 6 Gy per fraction per week for 3 weeks using image guidance. This is probably the first reported case of endometrial cancer with age related hyperkyphosis. In spite of the associated skeletal problems, a simple brachytherapy procedure is possible and provides good result.

Grand Challenges in global eye health: a global prioritisation process using Delphi method

Background: We undertook a Grand Challenges in Global Eye Health prioritisation exercise to identify the key issues that must be addressed to improve eye health in the context of an ageing population, to eliminate persistent inequities in health-care access, and to mitigate widespread resource limitations. Methods: Drawing on methods used in previous Grand Challenges studies, we used a multi-step recruitment strategy to assemble a diverse panel of individuals from a range of disciplines relevant to global eye health from all regions globally to participate in a three-round, online, Delphi-like, prioritisation process to nominate and rank challenges in global eye health. Through this process, we developed both global and regional priority lists. Findings: Between Sept 1 and Dec 12, 2019, 470 individuals complete round 1 of the process, of whom 336 completed all three rounds (round 2 between Feb 26 and March 18, 2020, and round 3 between April 2 and April 25, 2020) 156 (46%) of 336 were women, 180 (54%) were men. The proportion of participants who worked in each region ranged from 104 (31%) in sub-Saharan Africa to 21 (6%) in central Europe, eastern Europe, and in central Asia. Of 85 unique challenges identified after round 1, 16 challenges were prioritised at the global level; six focused on detection and treatment of conditions (cataract, refractive error, glaucoma, diabetic retinopathy, services for children and screening for early detection), two focused on addressing shortages in human resource capacity, five on other health service and policy factors (including strengthening policies, integration, health information systems, and budget allocation), and three on improving access to care and promoting equity. Interpretation: This list of Grand Challenges serves as a starting point for immediate action by funders to guide investment in research and innovation in eye health. It challenges researchers, clinicians, and policy makers to build collaborations to address specific challenges.

Nations within a nation: variations in epidemiological transition across the states of India, 1990–2016 in the Global Burden of Disease Study

18% of the world's population lives in India, and many states of India have populations similar to those of large countries. Action to effectively improve population health in India requires availability of reliable and comprehensive state-level estimates of disease burden and risk factors over time. Such comprehensive estimates have not been available so far for all major diseases and risk factors. Thus, we aimed to estimate the disease burden and risk factors in every state of India as part of the Global Burden of Disease (GBD) Study 2016
