    Tamil speakers were the most disparate, particularly with the /v/-/w/ contrast production. However, these deviations were often sporadic phonetic changes, which scarcely reflect robust speech patterns in the community. As a result, consonantal production in SgE is found to be largely independent of substrate influence and relatively uniform across the three ethnicities. The homogeneity observed in this study sheds light on bilinguals’ acquisition of sounds, and it also provides phonological evidence toward the understanding of the evolutionary process of postcolonial Englishes.Background Colorectal cancer (CRC) is the fourth leading cause of cancer-related death in the United States, despite being largely preventable and treatable. Improving overall screening rates among both men and women is considered an important and effective strategy toward reducing morbidity and mortality from CRC. In order to optimize screening strategies, factors associated with decreased compliance need to be understood. This study aimed to compare initial CRC screening rates between males and females in a population of patients who presented for an annual physical examination. Methods A retrospective chart review study of 380 patients designed to compare rates of initial CRC screening between males and females was conducted. Patients who were seen at our institution for an annual physical examination and were between 51 and 60 years of age were included. Results There was no evidence of a difference in the rate of initial colon cancer screening between females (83.0%) and males (80.9%) in either unadjusted analysis (odds ratio = 1.16, P = .59) or in multivariable analysis adjusting for potential confounding variables (odds ratio = 1.16, P = .61). Conclusions There was no significant difference in the rate of initial CRC screening between males and females who presented for an annual physical examination. This suggests that designing interventions to improve screening specific to gender may not be needed in a population of patients who attend routine preventive health examinations. Further study is needed in the general population to examine for gender-based differences in initial CRC screening among patients who do not regularly follow up for preventive examinations.This review provides an overview of the current understanding of the ontogeny and biology of melanoma stem cells in cutaneous malignant melanoma. This article also summarizes and evaluates the current knowledge of the underlying epigenetic mechanisms, the regulation of melanoma progress by the tumor microenvironment as well as the therapeutic implications and applications of these novel insights, in the setting of personalized medicine. Unraveling the complex ecosystem of cutaneous malignant melanoma and the interplay between its components, aims to provide novel insights into the establishment of efficient therapeutic strategies.Elder mistreatment is common in both community and institutional settings. However, the prevalence of elder mistreatment and its association with risk factors in sheltered homes are unknown. The primary objective of this study was to determine the prevalence and types of mistreatment among elderly living in sheltered homes. A second objective was to compare socio-demographics and other characteristics between elderly groups with or without a history of mistreatment. This cross-sectional study was conducted in 43 sheltered homes and utilized a face-to face, self-reporting interview with residents to complete structured question regarding each participant’s previous 12 months. The questionnaires included seven sections, including one section for demographics, five sections for subtypes of mistreatments (physical, psychological, financial, sexual, and neglect), and one section about health status and functional capacity. Among the 446 elderly participants, 81% of all participants experienced at least one type of mistreatment. Psychological was the most common type of elder mistreatment (71%), followed by neglect (67%), financial mistreatment (54%), and physical mistreatment (13%). Sexual mistreatment was rarely reported by the participants (0.01%). The most common risk factors associated with elder mistreatment were female gender and chronic illnesses. Elder mistreatment is common among the elderly living in sheltered homes, particularly in woman and those with chronic illness. Further studies are needed to better understand the risk factors that lead to the high prevalence of mistreatment in these settings.Since its first report in 1956 by Puck and Marcus, the clonogenic assay has not been completely adapted into high-content-screening (HCS) workflows despite the numerous automated systems available. Initially, clonogenic assays were used to observe the effects of radiation on cell survival, particularly with cancer cells. The clonogenic assay has since been well characterized as a measure of cancer stem cell (CSC) stemness, demonstrating that a single CSC can generate clonogenic colonies. CSCs are highly tumorigenic with an unlimited proliferation potential and capacity to generate malignant tumors. Furthermore, CSCs are also known to resist conventional chemotherapy as well as more contemporary targeted therapies alike. Therefore, given the complexity of CSCs and their clinical relevance, new methods must follow to more effectively study and characterize CSC mechanisms that allow them to proliferate and persist, and to develop drugs and other therapies that can more effectively target these populations. Herein, we present a HCS method to quantify the number and size of colonies in 2D and 3D culture models and to distinguish colonies based on fluorescent markers using an Opera Phenix high-content-screening system. In addition, we present a method to scan at low magnification and rescan at a higher magnification to capture in greater detail colonies or even single cells of interest. learn more These methods can be adapted to numerous applications or other imaging systems to study CSC biology using high-content analysis and for high-throughput drug discovery.Vascular access is necessary for hemodialysis, and in some cases where it is difficult to establish an arteriovenous fistula or arteriovenous graft, a permanent hemodialysis catheter may be used. However, serious catheter-related complications, such as central vein stenosis or thrombosis, can occur. We herein present a case of complete brachiocephalic vein obstruction in a patient with lupus nephritis receiving hemodialysis using a tunneled hemodialysis catheter. A 64-year-old patient underwent maintenance hemodialysis while taking an anticoagulant, with a tunneled hemodialysis catheter in the right internal jugular vein, because of arteriovenous fistula failure when hemodialysis was introduced. However, the catheter was removed because of a catheter-related bloodstream infection. Following the administration of antibiotics, an arteriovenous graft was implanted between the brachial artery and axillary vein in the right arm. Surprisingly, arteriovenous graft failure and complete obstruction of the right brachiocephalic vein were observed 3 days after arteriovenous graft creation.
