Living with multiple myeloma: A focus group study of unmet needs and preferences for survivorship care

Purpose: To describe the unmet informational, psychological, emotional, social, practical, and physical needs and preferences for posttreatment survivorship care of individuals living with multiple myeloma to inform the development of relevant, personcentered, survivorship services. Methods: An exploratory, descriptive study using 2 focus groups with 14 participants, 6 to 49 months postdiagnosis. Results: Thematic analysis revealed 7 key themes: information needs, experience with health-care professionals, coping with side effects, communicating with family and friends, dealing with emotions, support needs, and living with the chronicity of myeloma. Participants described key characteristics of survivorship care relevant to their needs and indicated they would like a more whole of person approach to follow-up when the main treatment phases had completed. Conclusion: Participants in this study described unmet needs across a breadth of domains that varied over time. The development of flexible, person-centered approaches to comprehensive survivorship care is needed to address the considerable quality-of-life issues experienced by people living with multiple myeloma. Nurse-led care may offer 1 viable model to deliver enhanced patient experience—providing the vital “link” that people described as missing from their survivorship care

A comparison of the distribution of pneumococcal types in systemic disease and the upper respiratory tract in adults and children

The serotype distribution of 874 strains of Streptococcus pneumoniae was determined in relation to patients' age and to frequency of isolation from systemic disease. Types 14 and 18, in pre-school children, and types 1, 4, 7, 8 and 12 in patients over 5 years of age were significantly associated with systemic disease whereas type 23 in pre-school children, and type 6 in older patients was associated with upper respiratory tract carriage. No significant difference was found in the incidence of other types in systemic disease compared to upper respiratory tract carriage. Fifteen diagnostic pneumococcal antisera (to types 1, 3, 4, 6, 7, 8, 9, 11, 12, 14, 17, 18, 19, 22 and 23) sufficed for typing 87% of strains

Toward a solution for cardiac failure in the newborn

The newborn infant with severe cardiac failure owed to congenital structural heart disease or cardiomyopathy poses a daunting therapeutic challenge. The ideal solution for both might be cardiac transplantation if availability of hearts was not limiting and if tolerance could be induced, obviating toxicity of immunosuppressive therapy. If one could safely and effectively exploit neonatal tolerance for successful xenotransplantation of the heart, the challenge of severe cardiac failure in the newborn infant might be met. We discuss the need, the potential for applying neonatal tolerance in the setting of xenotransplantation and the possibility that other approaches to this problem might emerge.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146972/1/xen12479.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146972/2/xen12479_am.pd

Religious education in the experience of young people from mixed-faith families

On the basis of recent ethnographic study at the University of Warwick of the religious identity formation of young people in ‘mixed-faith’ families, this article focuses on their (and their parents’) experiences and perceptions of religious education (RE) and of religious nurture in the community. The young people’s experience of RE differed between primary and secondary school and only a few were engaged in supplementary classes. We highlight the complementarity between school and home in young people’s religious learning and draw out implications for RE

HIV Epidemics in the European Region: Vulnerability and Response

This report provides a systematic review of the evidence on HIV vulnerability and response in all 53 countries of the WHO European Region, stretching from Iceland to the borders of China. It focuses on key populations most at risk of HIV infection: people who inject drugs, sex workers and men who have sex with men. It confirms that these populations are disproportionately affected by the growing HIV epidemic in Europe. Twenty-five percent of HIV diagnoses in Europe are associated with injecting drug use, with much higher proportions in Eastern Europe (33%) than in Western Europe (5%) and Central Europe (7%). Sex between men accounted for 10% of all HIV diagnoses, with higher rates reported in Western Europe (36%), followed by Central Europe (22%) and Eastern Europe (0.5%). HIV remains relatively low among female sex workers who do not inject drugs, (less than 1%), but higher among those who inject drugs (over 10%) as well as among male and transgender sex workers. The analysis highlights the pivotal role of social and structural factors in shaping HIV epidemics and HIV prevention responses. Poverty, marginalization and stigma contribute to the HIV epidemic in Europe and Central Asia. Economic volatility and recession risks are increasing vulnerability to HIV and infections. Barriers to successful HIV responses include the criminalization of sex work, of sex between men, and of drug use combined with social stigmatization, violence and rights violations. HIV prevention requires social and environmental change. The report calls for policymakers and HIV program implementers to target the right policies and programs to maximize the health and social impacts of Europe’s HIV responses and get higher returns on HIV-related investments. The report is a product of a collaboration between the World Bank, the London School of Hygiene and Tropical Medicine, the WHO Regional Office for Europe and UNAIDS

Large scale patterns of genetic variation and differentiation in sugar maple from tropical Central America to temperate North America

© 2015 Vargas-Rodriguez et al. Background: Geological events in the latter Cenozoic have influenced the distribution, abundance and genetic structure of tree populations in temperate and tropical North America. The biogeographical history of temperate vegetation that spans large ranges of latitude is complex, involving multiple latitudinal shifts that might have occurred via different migration routes. We determined the regional structuring of genetic variation of sugar maple (Acer saccharum subsp. saccharum) and its only subspecies in tropical America (Acer saccharum subsp. skutchii) using nuclear and chloroplast data. The studied populations span a geographic range from Maine, USA (46°N), to El Progreso, Guatemala (15°N). We examined genetic subdivisions, explored the locations of ancestral haplotypes, analyzed genetic data to explore the presence of a single or multiple glacial refugia, and tested whether genetic lineages are temporally consistent with a Pleistocene or older divergence. Results: Nuclear and chloroplast data indicated that populations in midwestern USA and western Mexico were highly differentiated from populations in the rest of the sites. The time of the most recent common ancestor of the western Mexico haplotype lineage was dated to the Pliocene (5.9 Ma, 95 % HPD: 4.3-7.3 Ma). Splits during the Pleistocene separated the rest of the phylogroups. The most frequent and widespread haplotype occurred in half of the sites (Guatemala, eastern Mexico, southeastern USA, and Ohio). Our data also suggested that multiple Pleistocene refugia (tropics-southeastern USA, midwestern, and northeastern USA), but not western Mexico (Jalisco), contributed to post-glacial northward expansion of ranges. Current southern Mexican and Guatemalan populations have reduced population sizes, genetic bottlenecks and tend toward homozygosity, as indicated using nuclear and chloroplast markers. Conclusions: The divergence of western Mexican populations from the rest of the sugar maples likely resulted from orographic and volcanic barriers to gene flow. Past connectivity among populations in the southeastern USA and eastern Mexico and Guatemala possible occurred through gene flow during the Pleistocene. The time to the most common ancestor values revealed that populations from the Midwest and Northeast USA represented different haplotype lineages, indicating major divergence of haplotypes lineages before the Last Glacial Maximum and suggesting the existence of multiple glacial refugia

Automated Discrimination of Pathological Regions in Tissue Images: Unsupervised Clustering vs Supervised SVM Classification

Recognizing and isolating cancerous cells from non pathological tissue areas (e.g. connective stroma) is crucial for fast and objective immunohistochemical analysis of tissue images. This operation allows the further application of fully-automated techniques for quantitative evaluation of protein activity, since it avoids the necessity of a preventive manual selection of the representative pathological areas in the image, as well as of taking pictures only in the pure-cancerous portions of the tissue. In this paper we present a fully-automated method based on unsupervised clustering that performs tissue segmentations highly comparable with those provided by a skilled operator, achieving on average an accuracy of 90%. Experimental results on a heterogeneous dataset of immunohistochemical lung cancer tissue images demonstrate that our proposed unsupervised approach overcomes the accuracy of a theoretically superior supervised method such as Support Vector Machine (SVM) by 8%
