RESUMO

The health problems caused by iron (Fe) and zinc (Zn) deficiency plague developing and underdeveloped countries. A vegetarian person mainly depends on cereal based diet with low quantity of Fe and Zn. Biofortification is an economical and sustainable approach to challenge the micronutrient malnutrition problem globally. Pearl millet (Pennisetum glaucum (L.) R. Br.) is one of the nutri-cereals and mostly grown under hot, dry conditions on infertile soils of low water-holding capacity, where other crops generally fail. It contains anti-nutrient compounds like phytic acid and polyphenols which reduce the mineral bioavailability because of their chelating properties. Biofortification of pearl millet is like a double-edged sword which cuts down the economic burden and simultaneously supplies required nutrition to the poor, offering a great scope for food security as well as nutritional security. With this background, this review focus on biofortification of grain Fe and Zn content in pearl millet. Genetic research on Fe and Zn uptake and accumulation in pearl millet grain is crucial in identifying the 'bottlenecks' in biofortification. The review also reveals the need and strategies for increasing bioavailability of Fe and Zn in humans by increasing promoters and decreasing anti-nutritional factors in pearl millet.

RESUMO

Iron (Fe) and zinc (Zn) deficiency has been identified as a major food-related health issue, affecting two billion people globally. Efforts to enhance the Fe and Zn content in food grains through plant breeding are an economic and sustainable solution to combat micronutrient deficiency in resource-poor populace of Asia and Africa. Pearl millet, Cenchrus americanus (L). Morrone, considered as a hardy nutri-cereal, is the major food crop for millions of people of these nations. As an effort to enhance its grain mineral content, an investigation was conducted using line × tester analysis to generate information on the extent of heterosis, gene action, combining ability for grain yield potential, and grain mineral nutrients (Fe and Zn). The partitioning of variance attributable to parents indicated that the lines and testers differed significantly for the traits studied. For most of the attributes, hybrids that were superior to the parents in the desired direction in terms of per se performance were identified. The analysis of combining ability variance indicated the preponderance of both additive and non-additive genetic effects. Thus, reciprocal recurrent selection can be used to develop a population with high-grain Fe and Zn contents. The Fe and Zn content in grain exhibited a highly significant and positive association between them, whereas the Fe and Zn contents individually showed a negative, albeit weak, correlation with grain yield and a moderate positive relation with grain weight. This indicates that mineral nutrient contents in grains can be improved without significant compromise on yield. The consistency of these trends across the environment suggests that these findings could be directly used as guiding principles for the genetic enhancement of Fe and Zn grain content in pearl millet.

RESUMO

Pearl millet is a climate-resilient, nutritious crop with low input requirements that could provide economic returns in marginal agro-ecologies. In this study, we report quantitative trait loci (QTLs) for iron (Fe) and zinc (Zn) content from three distinct production environments. We generated a genetic linkage map using 210 F6 recombinant inbred line (RIL) population derived from the (PPMI 683 × PPMI 627) cross using genome-wide simple sequence repeats (SSRs). The molecular linkage map (seven linkage groups) of 151 loci was 3,273.1 cM length (Kosambi). The content of grain Fe in the RIL population ranged between 36 and 114 mg/Kg, and that of Zn from 20 to 106 mg/Kg across the 3 years (2014-2016) at over the three locations (Delhi, Dharwad, and Jodhpur). QTL analysis revealed a total of 22 QTLs for grain Fe and Zn, of which 14 were for Fe and eight were for Zn on three consecutive years at all locations. The observed phenotypic variance (R 2) explained by different QTLs for grain Fe and Zn content ranged from 2.85 (QGFe.E3.2014-2016_Q3) to 19.66% (QGFe.E1.2014-2016_Q3) and from 2.93 (QGZn.E3.2014-2016_Q3) to 25. 95% (QGZn.E1.2014-2016_Q1), respectively. Two constitutive expressing QTLs for both Fe and Zn co-mapped in this population, one on LG 2 and second one on LG 3. Inside the QTLs candidate genes such as Ferritin gene, Al3+ Transporter, K+ Transporters, Zn2+ transporters and Mg2+ transporters were identified using bioinformatics approaches. The identified QTLs and candidate genes could be useful in pearl millet population improvement programs, seed, restorer parents, and marker-assisted selection programs.

RESUMO

OBJECTIVE: Compared to other chest wall malignancies, lymphoma is a common disease. However, published literature on a series of lymphoma cases involving the chest wall is scarce. The aim of the present study, was to describe experience with chest wall swellings diagnosed as lymphoid neoplasms on fine needle aspiration (FNA) cytology. METHODS: Eleven chest wall swellings were diagnosed as lymphoid neoplasms on FNA over a period of 15 years (January 2000-December 2014). The age of patients ranged from 19 to 73 years (median, 46). The male-to -emale ratio was 7:4. Ten cases had an anterior or lateral chest wall mass, and one swelling was in the scapular region. Six cases had concurrent lymphadenopathy, and one had bone involvement. The FNA smears were reviewed and classified under WHO Classification of Hematopoietic Neoplasms. The histopathological diagnoses were available in eight cases. RESULTS: The preliminary cytodiagnoses in 11 cases of chest wall lymphoid neoplasms were anaplastic large cell lymphoma (ALCL) in two cases, and ALCL/malignant melanoma, ALCL/T-cell-rich-B-cell lymphoma (TCRBCL)/Hodgkin's lymphoma (HL), plasmacytoma/neuroendocrine carcinoma, Hodgkin's lymphoma, small cell NHL/CLL, NHL, suggestive of NHL, post-transplant peripheral T-cell lymphoma (PTCL), and a malignant plasma cell tumour in one case each. The reviewed cytodiagnoses of lymphoid neoplasms were as follows: ALCL ( five cases), centroblastic lymphoma (two cases), and small cell lymphoma/CLL, post-transplant peripheral T-cell lymphoma, Hodgkin's lymphoma and plasmacytoma (one case each). Histopathological diagnoses available in eight cases confirmed the presence of lymphoid neoplasms. CONCLUSION: A variety of lymphoid neoplasms involved the chest wall, and among them, ALCL was a common form.

RESUMO

BACKGROUND: Adult whole-organ donation after circulatory death (DCD) and 'split' extended right lobe donation after brain death (ERL-DBD) liver transplants are considered marginal, but direct comparison of outcomes has rarely been performed. Such a comparison may rationalize the use of DCD livers, which varies widely between UK centres. METHODS: Outcomes for adult ERL-DBD livers and 'controlled' DCD liver transplantations performed at the Cambridge Transplant Centre between January 2004 and December 2010 were compared retrospectively. RESULTS: None of the 32 patients in the DCD cohort suffered early graft failure, compared with five of 17 in the ERL-DBD cohort. Reasons for graft failure were hepatic artery thrombosis (3), progressive cholestasis (1) and small-for-size syndrome (1). Early allograft dysfunction occurred in a further five patients in each group. In the DCD group, ischaemic cholangiopathy developed in six patients, resulting in graft failure within the first year in two; the others remained stable. The incidence of biliary anastomotic complications was similar in both groups. Kaplan-Meier survival analysis confirmed superior graft survival in the DCD liver group (93 per cent at 3 years versus 71 per cent in the ERL-DBD cohort; P = 0·047), comparable to that of contemporaneous whole DBD liver transplants (93 per cent at 3 years). Patient survival was similar in all groups. CONCLUSION: Graft outcomes of DCD liver transplants were better than those of ERL-DBD liver transplants. Redefining DCD liver criteria and refining donor-recipient selection for ERL-DBD transplants should be further explored.

RESUMO

OBJECTIVE: Hyaline-vascular Castleman's disease (CD) is difficult to diagnose on fine needle aspiration and may be mistaken to be a lymphoreticular malignancy because of the presence of large cells having nuclei showing atypical features. The cytomorphological findings in three histopathologically documented cases of hyaline-vascular CD were evaluated to a set of cytomorphological criteria which could help in the identification of this condition on aspirate smears. METHODS: The Papanicolaou and Diff-Quik stained smears from three cases of histologically documented hyaline-vascular CD were reviewed by one author. After review the following cytomorphological criteria were suggested to be indicators of the lesion. (i) The presence of large oval to round cells having ill-defined cytoplasmic margins and large nuclei with irregular nuclear outlines having fine or coarse chromatin giving a crumpled tissue paper appearance. (ii) A polymorphous population of lymphoid cells predominantly of small lymphocytes in the background. The smears from these three cases were then mixed with smears from four cases of reactive lymphoid hyperplasia and three cases of Hodgkin's lymphoma. These ten cases were blindly evaluated by two other cytopathologists in order to evaluate the utility of the proposed criteria in identifying CD. RESULTS: The cytomorphological criteria seen in the methodology section were present in all the cases. These features were helpful in distinguishing CD from reactive lymphoid hyperplasias and Hodgkin's Lymphomas in all cases except one case. CONCLUSION: Although hyaline-vascular CD is a difficult diagnostic entity on aspirate material the presence of large histiocytic cells with a crumpled tissue paper appearance of the nuclei in a background of small lymphocytes are useful indicators for suspecting this lesion. However, these findings should be analysed in larger studies to determine if they could in anyway reduce the diagnostic dilemma in cases of CD.

RESUMO

This descriptive study used admission level data of 1040 patients to find out the readmission rate and its possible contributing factors within 30 days of discharge in a selected Armed Forces Hospital (Combined Military Hospital, Dhaka). The patients were grouped according to their admission status like group-I (readmission within 30 days of previous discharge), group-II (readmission after 30 days of previous discharge) and group-III (newly admitted patients). The readmission rate at the study period was 9.5% in group-I and 10.2% in group-II. The overall readmission rate was 19.7%. Disease pattern revealed that patients with surgical ailments (25.3%) comprised the greatest number of readmissions followed by cardiovascular diseases (19.2%) and neoplasm (10.1%). Bivariate analyses between two groups (group-I and group-II) were carried-out on different conditions of readmitted patients. No significant relationship was found between different conditions of the readmitted patients with previous stay in the hospital except adequacy of treatment. It was found that the proportion of readmission was higher in group-I among the patients who perceived that their treatment was not adequate during previous stay. This study was aimed for assessment of quality of care in order to find out the relationship between quality of care and readmission status. No statistically significant difference was found among the three groups of patients in overall quality of care (p>0.05). It is widely believed that hospital readmission has a relationship with the substandard care in previous stay. But findings of this study were not consistent with the findings of other study. Therefore, it can be concluded that readmission in an armed forces hospital is probably related with the different characteristics of the study population, disposal procedure of disease condition and the attitude of the physicians towards admission process. Further investigation and strategies, combined with reduction of avoidable admission and better screening are required to prevent this adverse outcome.

RESUMO

OBJECTIVE: Endometriosis due to ectopic endometrial tissue that responds to hormonal stimulation and is extremely rare in a surgical scar appearing in 0.1% of women who have undergone Caesarean section. Fine needle aspiration cytology (FNAC) can be a valuable diagnostic aid in the evaluation of these subcutaneous abdominal masses. METHODS: We present the cytomorphological spectrum in eight cases of abdominal wall endometriosis diagnosed by FNAC over a 6-year period (June 1998-June 2004) in Mubarak Al-Kabeer Hospital (Kuwait). The patients ranged from 27 to 56 years of age. Seven had a prior Caesarean section and one had a hysterectomy for fibroid. They presented 3-8 years later with nodules in/near the abdominal scar. Five cases presented with a painful nodule, fluctuant with the menstrual cycle. RESULTS: Cytological findings comprised epithelial clusters and fusiform stromal cells with numerous haemosiderin-laden macrophages. Mild to moderate epithelial atypia was observed in three cases. A diagnosis of endometriosis was rendered in all the eight cases and tissue was available in four cases. CONCLUSIONS: Endometriotic nodules need to be differentiated from other benign/malignant masses and evaluated for possible malignant transformation. FNAC provides a safe and effective tool for diagnosis thereby obviating the need for other procedures.

RESUMO

Concerns regarding the 'fitness for practice' of registered nurses in the UK stimulated robust partnership models to improve practice learning. In Australia, escalating costs resulted in minimal time spent in 'off campus' clinical learning. An RCN funded Education Scholarship supported an investigation of practice learning in Australia in comparison to the Bournemouth Collaborative Model. Focusing on the contextual arrangements for practice learning and the Clinical Facilitator (Australia) role, information was obtained through document analysis, informal interviews, and observations at four university sites. In contrast to the emerging positive partnership models in the UK, problems with funding had a negative impact on relationships between Health Agencies and Australian Universities. Clinical exposure for UK students has increased while Australian students have short focused 'off campus' placements. In the UK, Practice Educators (PEs) provide support for 'qualified' mentors who have a key role in the assessment of student competence. Clinical Facilitators (CFs) in Australia, prepared through completion of two day workshops/courses, undertake a combined facilitator and assessor role. Of primary concern in both countries is the political commitment to provide adequate funding. Although national policy documents attest to recognising the need; competing demands threaten the allocation of funding for a diffuse longer-term goal.

RESUMO

In this study, we evaluated the usefulness of fine needle aspiration cytology (FNAC) in the diagnosis of soft tissue tumours. We have also assessed the various pitfalls of FNAC of soft tissue tumours. This was a retrospective study and here we analysed only 82 histopathology proven cases of FNAC of soft tissue tumours diagnosed in a five and half year period. On histopathological examination, 55 of these cases were malignant and 27 were benign. There was a total of 15 recurrences and histopathology was available prior to FNAC in only eight of these cases. Therefore, excluding these eight cases, malignant tumours were primarily diagnosed by FNAC in 47 cases. The sensitivity, specificity and positive predictive value of FNAC in diagnosis of soft tissue tumours were 91.5%, 92.5% and 95.5%, respectively. Only 22 of 47 cases (46.8%) were correctly categorized. There were two false-positive and four false-negative cases. One case each of fibromatosis and schwannoma were reported as sarcoma. False-negative cases were fibrosarcoma (1), malignant nerve sheath tumour (2) and haemangiopericytoma (1). FNAC was very useful in distinguishing benign from malignant soft tissue tumours. However, it was not so effective in exact categorization of tumours.

RESUMO

Subependymomas are highly differentiated slow growing gliomas. They are one of the few gliomas which are biologically benign. They are extremely rare in children. However, after going through the histopathology records of our department of fourteen years (1983-1997) we found that five (20%) cases of subependymomas have been diagnosed in children out of a total of twenty-six subependymomas. Two of our cases showed the presence of osseous metaplasia, a hitherto undescribed finding.

RESUMO

BACKGROUND: Skin biopsy and scrape smear examination are the two most commonly employed investigatory techniques in the diagnosis of cutaneous leishmaniasis. Although cases Leishmania lymphadenitis are reliably diagnosed with fine needle aspiration (FNA) cytology, it has not attained popularity in the diagnosis of cutaneous leishmaniasis, and only a few reports are available. CASE: A 6-month-old Kuwaiti child presented with a skin lesion on her left forearm of five months' duration. Both scrape smears and FNA were performed from the lesion. FNA cytology smears showed a rich population of inflammatory cells predominating in lymphocytes and histiocytes and epithelioid cell granulomas. The amastigote forms of Leishmania were noted on the smears. The scrape smears were nondiagnostic. CONCLUSION: FNA cytology can be reliably used in the diagnosis of cutaneous leishmaniasis, especially in dry lesions, where scrape smears are likely to be nondiagnostic.

RESUMO

BACKGROUND: Granular cell tumors are neoplasms of uncertain histogenesis, although a neural origin is favored. Most reports on the cytologic features of granular cell tumors have been on lesions from the breast or respiratory tract. However, there are only a few reports on fine needle aspiration (FNA) cytologic diagnosis of cutaneous or soft tissue granular cell tumors. CASE: A 7-year-old girl presented with a skin lesion on her right forearm of one year's duration. The FNA smears showed sheets and clusters of oval to polygonal cells with an abundant amount of granular cytoplasm. Many single, scattered cells with similar morphology were seen in the background. Immunostaining for S-100 protein showed granular cytoplasmic positivity. The tumor was diagnosed as a benign granular cell tumor. The histopathology report on the excised lesion confirmed the FNA diagnosis. CONCLUSION: The cytopathologic features of granular cell tumors presenting as skin lesions are distinctive enough to allow a correct diagnosis on FNA cytology.

RESUMO

Against a background of increasing concern over the widening theory practice gap and research evidence of problems in providing quality practice education, the English National Board (ENB) commissioned an 18 month study into the role of the teacher/lecturer in practice. This article, after providing a brief overview of the background, literature and methods, outlines the results from the Adult Case Study stage of the research. Documents, individual and focus group interviews of lecturers (n = 76), practitioners (n = 46) and students (n = 131) in five schools of nursing and midwifery provided data for analysis. A role labeled as 'link lecturer' was the most common approach acknowledged by all respondent groups. Despite overt commitment to the practice role by schools of nursing and midwifery, findings indicate that lecturers are unprepared, unsupported and unmonitored. Students and practitioners had very variable experiences and expressed a strong need for a better-organized approach which would provide them with consistent and sustained support in the practice setting. Overall the study highlighted a lack of strategic management of the practice role by university schools of nursing and midwifery. Convergence of findings from midwifery and the other branches of nursing provides strong research evidence for recommendations for more active management of the practice curriculum to be implemented as part of any future proposed reforms for nurse education in the UK.

RESUMO

PURPOSE: To examine the growth and diffusion through the USA and UK literature of nurses claims to patient advocacy. DESIGN: A bibliometric analysis of articles cited under the key descriptor "patient advocacy" in the International Nursing Index (INI) was undertaken. Analysis included output in 5-year accumulations from 1976 to 1995, and was focused on quantity of output and exposition of concerns through interpretation of the titles. Citation mapping was undertaken to trace dominant influences in the diffusion process. METHODS: Titles and countries of origin of the journal along with year of publication were organized into a database to provide quantitative material on comparative output from the USA and the UK. Citation profiles of key influencing authors were examined. FINDINGS: A role in patient advocacy was proposed in the American nursing literature in the late 1970s and in the British literature a decade later. Support for the role was evident in its use in professional organizations and schools. The pattern of dissemination illustrates the influence of American nursing on the professional role of nurses in the UK. CONCLUSIONS: On the basis of a stages model for diffusion of an innovation, patient advocacy has reached only preliminary stages of acceptance as an innovation in nursing.

RESUMO

In recent years, patient advocacy has been claimed as an integral part of the nurse's role in health care delivery in the United Kingdom (UK). Support from the nursing leadership/elite is seen as important in the promulgation and diffusion of any 'new' role in nursing. This paper explores the perceptions and attitudes of nurse leaders in the UK to the adoption of the patient advocate role as an 'innovation' in nursing. Using a qualitative methodology, semi-structured interviews with six of nursing's 'elite' were conducted over a period of 5 months. Results revealed contradictions and paradoxes within the views of the elite. Although leaders recognized patient advocacy as a role integral to the moral value system in nursing enhanced by the nurse-patient relationship, they objected to the professionalization of the role, seeing an exclusive claim to patient advocacy as intensifying interprofessional conflicts in health care. It is argued that unless professionalized, the individual nurse will continue this potentially risky activity without adequate authority or support systems. The results overall question the role of the nursing leadership in the diffusion of innovations in nursing.

RESUMO

Survival and long-term prognosis after a myocardial infarction are directly related to the individuals's decision to seek medical help. Early medical intervention is imperative if thrombolytic therapy is to be effective. Emerging research has indicated that women frequently have longer pre-hospital delays than men. Incorporating a comparative descriptive design, this research compared the pre-hospital admission behaviour patterns of women and men, following the onset of acute chest pain. A convenience sample of 12 women and 12 men were selected following admission to a local coronary care unit. Structured interviews and the examination of medical notes/relevant documentation provided the data. Findings were examined and compared through the use of content analysis and descriptive statistics. Severity of symptoms proved to be the strongest influence in shortening pre-hospital delay. Despite this, overall, men were admitted to hospital more quickly than women. Men were more ready than women to believe that they might be having a heart attack and this belief led them to seek treatment promptly. In order to improve female mortality and morbidity following a myocardial infarction, it is recommended that there is an urgent need to target women, through health promotion and media interventions.

RESUMO

The Scope of Professional Practice (UKCC 1992) has significantly altered the interpretation of nurses' roles, emphasizing individual professional accountability and clinical decision-making. However, 5 years after the issue of the document, uncertainties remain regarding interprofessional legal accountability between medicine and nursing. To investigate issues surrounding role extension or expansion in intensive care nursing, a small qualitative study was conducted centred on one intensive care unit (ICU) within a large teaching hospital. Data were collected by semi-structured interviews from a purposive sample of five senior intensive care nurses and three consultant anaesthetists. Four major categories emerged, identified as: interpretation confusion; education for change; struggles for power and task versus autonomy. The findings revealed that the senior critical care nurses identified themselves as independent, autonomous practitioners involved in clinical decision-making. However, there was evidence of a reluctance to empower more junior staff to perform extended or expanded roles. Medical respondents viewed extended or expanded roles as taking on mechanical tasks for which anyone could be trained to perform. In conclusion, it is argued that although nursing is maturing in its growth towards professionalization, broader issues such as the legal quagmire, failure to adopt the philosophy of role expansion and the existence of sacred boundaries intra- and inter-professionally need to be addressed.

RESUMO

The potential to improve patient/client care, stimulate the personal and professional growth of the practitioner and help close the theory practice gap has provoked much discussion in the nursing literature on the benefits of reflection on practice. In order to examine recent developments in this area, a study tour, supported by the Florence Nightingale Foundation, was conducted in Australia and the UK during the spring and summer of 1995. Using an illuminative case study approach, data collected demonstrated that although reflective practice was fully endorsed by the nursing profession in Australia, and there were excellent examples of reflective practice in use, the continued growth of the reflective practice movement appeared to be threatened by the rationalization of both clinical and theoretical education in the universities. Issues around methods of encouraging reflection in students focused on ethical use of journals, the levels of reflection developed and the outcome effectiveness of reflective learning.
