The application of crime science to the prevention of elder abuse

The abuse of older people is a significant problem, with estimates intimating that there may be over 340,000 cases per year in the United Kingdom. Despite improvements in screening and assessment to identify and treat those who are abused or at risk of abuse, the healthcare community remains preoccupied with prevalence rather than prevention. In light of the paucity of health-related research evidence to support the effectiveness of preventative measures, the application of crime prevention theory and knowledge is appropriate. Routine activity theory and situational crime prevention literature acknowledges the vulnerability of older people to abuse and the potential of any person employed as a carer to be an abuser. Preventative measures are focused on techniques that make abuse more difficult and more risky for the perpetrator and, therefore, less 'rewarding'. The regulation of healthcare support workers and increased workplace surveillance are examples of the 25 techniques of situational prevention that could be applied in a healthcare setting.     

Sarcoid Myelopathy

A 45-year-old woman with history of iritis, uveitis, and sarcoidosis of the skin presented with a subacute cervical myelopathy. Magnetic resonance imaging (MRI) ;howed patchy, multifocal, gadoliniumenhancing intramedullary lesions of the spinal cord, and extramedullary lesions of the basal cisterns and fourth ventricle. Symptoms and MRI abnormalities were improved within 1 month of corticosteroid therapy.     

Distribution of metabotropic glutamate receptor mGluR5 immunoreactivity in rat brain

The receptor mGluR5 is a metabotropic glutamate receptor with messenger RNA abundantly present throughout cortex, hippocampus, and caudate/putamen that is also coupled to phosphatidyl inositide hydrolysis and calcium mobilization. In this study, the distribution of mGluR5 was examined in rat brain by immunocytochemistry. The antibody utilized is highly specific and does not cross react with the most closely related other metabotropic glutamate receptor, as determined by Western blot analysis of nonneuronal cells transfected with metabotropic receptor coding sequences. The receptor mGluR5 is widely expressed with the highest density in olfactory bulb, caudate/putamen, lateral septum, cortex, and hippocampus, as confirmed with both immunocytochemistry and Western blot analysis. Electron microscopic studies in hippocampus and cortex indicate that the labeling is mostly on membranes of dendritic spines and shafts. Light and electron microscopic evidence indicates that some mGluR5 immunoreactivity is located in presynaptic axon terminals, suggesting that mGluR5 may function as a presynaptic receptor.     

Changing perspectives in children hospitalized with poststreptococcal acute glomerulonephritis

Changing perspectives in 95 children with poststreptococcal acute glomerulonephritis (PSAGN) in our hospital between 1979 and 1988 are reported. Between 1961 and 1970 an average of 31±6.3 patients/year with PSAGN were treated and 70% had antecedent pyoderma. In the present study antecedent pharyngitis was observed in 59 children und pyoderma in 36. In comparison to the decade ending in 1970 our data show: (1) a marked decline in the prevalence of PSAGN (P=<0.0005), (2) a predominance of antecedent pharyngeal infection (P=0.044), (3) a decline in urban and an increase in rural patients with PSAGN (P=0.0483); and in the last decade: (1) a predominance of antecedent pharyngeal infection in children over 6 years of age (P=0.0009) and (2) a predominance of antecedent pyoderma in black children (P=0.0004).     

PHARMACOLOGIC MANAGEMENT OF COMMON MUSCULOSKELETAL DISORDERS IN WOMEN

The range of musculoskeletal disorders encountered in primary care settings is broad, extending from simple injuries to complex chronic diseases. Assessment, management, referral, and pharmacologic intervention for many of these conditions may fall to certified nurse-midwives who increasingly are assuming primary care responsibilities.     

Characterization and phenotypic analysis of differentiating CD34+human bone marrow cells in liquid culture

Abstract: Our current understanding of human haematopoietic stem cell biology is based in part on the characterization of human CD34⁺ bone marrow cell differentiation in vitro. CD34 is highly expressed on early stem cells and haematopoietic progenitor cells with clonogenic potential and is gradually lost during differentiation and commitment. However, CD71 (transferrin receptor) is expressed at low levels on early stem cells and generally increases during haematopoietic progenitor cell proliferation. We reasoned that the combination of these surface markers would provide a useful framework for the simultaneous analysis of multiple lineage differentiation of CD34⁺ haematopoietic progenitor cells in liquid culture. In this report, we identify the phenotype of distinct subpopulations of myeloid, erythroid and lymphoid cells in liquid suspension culture using differential expression of CD34 vs. CD71 in combination with specific lineage markers. Freshly isolated human CD34⁺ bone marrow cells were introduced into suspension culture and monitored over a 6-d period using 3-colour flow cytometry. This is the first demonstration that differential expression of CD34 vs. CD71 can be used to simultaneously monitor differentiation of multiple haematopoietic cell lineages in liquid suspension culture, facilitating the study of cytokine-, drug- or chemical-induced alterations in haematopoietic progenitor cell differentiation in vitro.     

Transfection with bacterial genes as a marker for cells seeded on vascular flow surfaces

Autologous seeding of vascular grafts has been in use since 1972; however, the fate of seeded cells has never been determined. While short-term retention has been determined by radioactively labeling cells, long-term studies of seeded cells have not been possible due to the lack of an appropriate marker system. We have developed a long-term marker system for endothelial cells by transfecting the cells with bacterial genes that can be detected by fluorescentally-labeled antibodies to these markers. Two bacterial genes, neo and cat both carried by a pSV2 plasmid construct were used to co-transfect cells. Transfects were selected by growth in the presence of G418. Transfected clones were expanded into monolayers that stained positive for cat by fluorescence, and retained the normal cobblestone morphology and factor VIII staining of endothelial cells. By stably transfecting cells with bacterial genes these cells can now be used to seed vascular grafts and follow the long-term fate of seeded cells.     

Spina Bifida: The Transition into Adulthood Begins in Infancy

Many concerns surround the preparation of a person with spina bifida for a successful transition into adult life and responsibilities. A model of intervention must be based on developmental concerns and timely issues from infancy through all stages of development to young-adult life. This article discusses, within a developmental framework, issues of transition in relation to physical, social, emotional, and educational/vocational needs; it also presents a conceptual framework for the transition into adulthood. Guidelines were developed by incorporating expected outcomes of people with spina bifida and using a philosophical framework that encompasses the achievement of a balance among dependence, independence, and interdependence. This model is based on developmental issues from infancy through all stages of development to young-adult life. Using this framework for care, the rehabilitation nurse can feel confident that the needs of clients with spina bifida and similar chronic conditions are being met.     

Segregation analysis of diastolic blood pressure in a large pedigree

Hypertension, a major risk factor for cardiovascular diseases, is thought to be inherited to some extent. However, the nature of its genetic component remains unresolved. In the present study, data from a single large kindred (the HGAR1 pedigree) were used to search for evidence of single gene and multifactorial effects on diastolic blood pressure. Commingling analyses found that a mixture of three distributions fit the data significantly better than a single normal distribution, suggesting a major effect influencing diastolic blood pressure levels. However, segregation analysis, using regressive models, indicated that the transmission probabilities were not consistent with Mendelian expectations. There was no evidence of either major gene or polygenic effects on diastolic blood pressure levels in this family. © 1993 Wiley-Liss, Inc.
