Exploring the health visiting service from the view of South Asian clients in England: a grounded theory study

The fact that health inequalities disproportionately affect the minority ethnic population is not new and projections are that the minority ethnic population will continue to increase. The importance of early intervention and the key role that health visitors can play in attempting to reduce health inequalities is well documented as is the requirement for health providers to establish culturally sensitive services. To date, much of the research has focused on the perspectives of healthcare professionals caring for minority ethnic clients in hospital‐based settings and little is known about the perspectives of minority ethnic clients regarding the health visiting service (HVS). The aim of this study was to explore the perspectives of South Asians regarding their experiences with the HVS. The study was conducted in a small town in the South of England between March and June 2013. A qualitative study using a grounded theory approach was used to capture the perspectives of this group regarding their interactions with the HVS. The sample consisted of 15 participants and data were collected through audio‐recorded semi‐structured interviews and analysed using constant comparative approach. Three key categories were identified: ‘understanding the health visitor's role’, ‘sensitivity of services’ and ‘the significance of family’. While clients valued one‐to‐one support from health visitors, there was some evidence of poor communication and ethnocentric tendencies within the service. It was found that South Asian clients distinguish between health and parenting advice, being more likely to accept health advice from their health visitor and more likely to accept parenting advice from their family. The findings, although limited in their generalisability, offer important insights into how South Asians perceive the service and will equip health visitors with a better understanding of how best to improve the experience of South Asian clients accessing the health visiting.

Existence of a pool of T-lymphocyte colony-forming cells (T-CFC) in human bone marrow and their place in the differentiation of the T- lymphocyte lineage

The existence and characteristics of bone marrow T-cell progenitors have not yet been established in man. Several pieces of evidence such as the reconstitution of certain immunodeficiencies by bone marrow graft suggest that T-cell precursors are present in the bone marrow. We report the growth of T-cell colonies from bone marrow populations using PHA-stimulated lymphocyte-conditioned medium containing T-cell growth factor (TCGF). Rosetting experiments and complement-dependent cytotoxicity assays with monoclonal antibodies indicate that the bone marrow T colony-forming cells (T-CFC) are E- OKT 3- and la+, i.e., immature progenitors. The colonies derived from these cells have the phenotype of mature T cells: E + OKT 3 + la- with either helper (OKT 4+) and suppressor (OKT 8 +) antigens. These results suggest that a thymic microenvironment may not be necessary for the in vitro proliferation and differentiation of the T-cell lineage in adult humans. These methodologies may permit direct investigation of early phenomena concerning the T-cell lineage, such as the acquisition of self-tolerance, the formation of a repertoire of specificities, and the HLA restriction phenomena that we believe takes place before the thymic maturation.     

Detection of homozygous deletions of the cyclin-dependent kinase 4 inhibitor (p16) gene in acute lymphoblastic leukemia and association with adverse prognostic features

A recently described putative tumor suppressor gene, the cyclin- dependent kinase 4 inhibitor (p16), has been shown to be altered by deletions and/or point mutations in various human cancers. To assess the incidence and clinico-biologic correlations of p16 homozygous deletion in hemopoietic tumors, we studied a panel of 244 DNA samples representative of distinct acute (99 cases) and chronic (57 cases) leukemia subtypes, myelodysplastic (22 cases) and myeloproliferative (15 cases) syndromes, and lymphomas (51 cases). A 361-bp probe complementary to the p16 exon 2 gene sequences was generated by polymerase chain reaction and used in Southern blot hybridization against these tumor DNAs. Homozygous deletions of p16 (p16-/-) were detected in 10 of 58 (17%) cases of acute lymphoblastic leukemia (ALL) of either B or T lineage and in no other tumors. Single-strand conformation polymorphism analysis of p16 exons 1 and 2 was also performed in 40 of the 58 ALL cases and in 16 lymphomas. In no cases were point mutations detected. The comparison of clinical features at presentation in p16-/- and in p16 germline ALL cases showed a greater leukemic cell mass (P = .001) and higher white blood cell counts (P = .01) in the former group. Two ALL cases in which diagnostic and relapse DNA samples were available showed p16-/- in both specimens. We conclude that homozygous p16 gene deletions characterize a subset of ALL with features of aggressive disease.     

Incorporating a service improvement project into an undergraduate nursing programme: A pilot study

Although service improvement projects have been incorporated into some postregistration nurse education modules in the UK, they have not been generally available to pre‐registration students. This paper reports on the implementation and evaluation of a pilot project in pre‐registration nurse education at one university in eastern England. It concludes that the nursing students found the project to be a useful addition to their course. Supportive reactions were obtained from nurse managers, mentors and academics. A need to improve communication with clinical areas through the use of web‐based materials was highlighted.
