Rapid diagnostic tests for the home-based management of malaria, in a high-transmission area.

Rapid diagnostic tests (RDT) are sometimes recommended to improve the home-based management of malaria. The accuracy of an RDT for the detection of clinical malaria and the presence of malarial parasites has recently been evaluated in a high-transmission area of southern Mali. During the same study, the cost-effectiveness of a 'test-and-treat' strategy for the home-based management of malaria (based on an artemisinin-combination therapy) was compared with that of a 'treat-all' strategy. Overall, 301 patients, of all ages, each of whom had been considered a presumptive case of uncomplicated malaria by a village healthworker, were checked with a commercial RDT (Paracheck-Pf). The sensitivity, specificity, and positive and negative predictive values of this test, compared with the results of microscopy and two different definitions of clinical malaria, were then determined. The RDT was found to be 82.9% sensitive (with a 95% confidence interval of 78.0%-87.1%) and 78.9% (63.9%-89.7%) specific compared with the detection of parasites by microscopy. In the detection of clinical malaria, it was 95.2% (91.3%-97.6%) sensitive and 57.4% (48.2%-66.2%) specific compared with a general practitioner's diagnosis of the disease, and 100.0% (94.5%-100.0%) sensitive but only 30.2% (24.8%-36.2%) specific when compared against the fulfillment of the World Health Organization's (2003) research criteria for uncomplicated malaria. Among children aged 0-5 years, the cost of the 'test-and-treat' strategy, per episode, was about twice that of the 'treat-all' (U.S.$1.0. v. U.S.$0.5). In older subjects, however, the two strategies were equally costly (approximately U.S.$2/episode). In conclusion, for children aged 0-5 years in a high-transmission area of sub-Saharan Africa, use of the RDT was not cost-effective compared with the presumptive treatment of malaria with an ACT. In older patients, use of the RDT did not reduce costs. The question remains whether either of the strategies investigated can be made affordable for the affected population.

La constitució de la naturalesa moral de l'home

En aquest treball filosòfic pretenem reflexionar sobre l'origen natural del fet moral, tot fent una comparació amb fets culturals, com ara, els Drets Humans o la mutilació genital femenina. La conclusió és que la moral es basa en el sentit dels comportaments més que no els comportaments en si mateixos.

Ultrasound Biomicroscopy Evaluation of Anterior Extension of Retinoblastomas : A Clinico-Pathological Study

Purpose: Extension of retinoblastoma cells anterior to the vitreous surface is a criteria used to categorize retinoblastomas in Group E. In some cases, the assessment of anterior chamber invasion is readily visible by slit lamp examination, but in other cases, invasion of the posterior chamber is clinically difficult to determinate. Ultrasound biomicroscopy (UBM) allows high-resolution images of the anterior segment and structures normally hidden from clinical visualization such as ciliary body, zonule or posterior chamber. This prompted us to evaluate the value of UBM in the assessment of posterior and anterior chamber involvement in patients with peripheral extending retinoblastomas. Methods: We retrospectively reviewed all retinoblastoma cases that underwent enucleation in our institution from 1.1996 till 12.2009 in which UBM ( 35-MHz or 50-MHz) evaluation was available. The UBM results were compared with the histopathological data. Results: From 1.1996 till 12.2009, 146 enucleations were performed in our institution. UBM information was available in 18 cases. There were 8 males and 10 females. The mean age was 4 years old. UBM allowed correct assessement of posterior chamber invasion in 15 cases (13 cases with retinoblastoma in the posterior chamber and 2 cases without retinoblastoma in the posterior chamber). There was a significant correlation between the presence of retinoblastoma cells in the posterior chamber detected by UBM and the histopathological confirmation of posterior chamber involvement (p=0,0008). The sensitivity of UBM in the assessment of posterior chamber invasion by retinoblastoma was 81% and the specificity 100%. UBM allowed correct assessment of anterior chamber invasion in 13 cases. The sensitivity of UBM for this purpose was 50% and the specificity 60 %. Conclusions: In selected cases of advanced retinoblastoma, UBM appears to represent a valuable tool in the evaluation of the precise extension of the disease. Although our series encompasses only a limited number of cases, the sensitivity and specificity of UBM in the assessment of retinoblastoma anterior extension is interesting. Further prospective multi-centered clinical studies would be necessary to better delineate the utility of this method in the precise categorization of retinoblastoma anterior extension

Decreased local control following radiation therapy alone in early-stage glottic carcinoma with anterior commissure extension.

PURPOSE: To assess the patterns of failure in the treatment of early-stage squamous cell carcinoma of the glottic larynx. PATIENTS AND METHODS: Between 1983-2000, 122 consecutive patients treated for early laryngeal cancer (UICC T1N0 and T2N0) by radical radiation therapy (RT) were retrospectively studied. Male-to-female ratio was 106 : 16, and median age 62 years (35-92 years). There were 68 patients with T1a, 18 with T1b, and 36 with T2 tumors. Diagnosis was made by biopsy in 104 patients, and by laser vaporization or stripping in 18. Treatment planning consisted of three-dimensional (3-D) conformal RT in 49 (40%) patients including nine patients irradiated using arytenoid protection. A median dose of 70 Gy (60-74 Gy) was given (2 Gy/fraction) over a median period of 46 days (21-79 days). Median follow-up period was 85 months. RESULTS: The 5-year overall, cancer-specific, and disease-free survival amounted to 80%, 94%, and 70%, respectively. 5-year local control was 83%. Median time to local recurrence in 19 patients was 13 months (5-58 months). Salvage treatment consisted of surgery in 17 patients (one patient refused salvage and one was inoperable; total laryngectomy in eleven, and partial laryngectomy or cordectomy in six patients). Six patients died because of laryngeal cancer. Univariate analyses revealed that prognostic factors negatively influencing local control were anterior commissure extension, arytenoid protection, and total RT dose < 66 Gy. Among the factors analyzed, multivariate analysis (Cox model) demonstrated that anterior commissure extension, arytenoid protection, and male gender were the worst independent prognostic factors in terms of local control. CONCLUSION: For early-stage laryngeal cancer, outcome after RT is excellent. In case of anterior commissure extension, surgery or higher RT doses are warranted. Because of a high relapse risk, arytenoid protection should not be attempted.

Five Years Of Denosumab Treatment In Women With Postmenopausal Osteoporosis: Preliminary Results From The Freedom Extension Study

Aims: The pivotal FREEDOM study evaluated the effi cacy and safety of 3 years' denosumab treatment in women with postmenopausal osteoporosis (PMO).1 Since osteoporosis is a chronic condition requiring long-term therapy, FREEDOM was extended to further elucidate the safety and effi cacy of long-term denosumab administration. We present data from the fi rst 2 years of this extension, representing up to 5 years' continuous exposure to denosumab.Methods: Patients who completed FREEDOM were eligible for the extension. Women continued to receive (long-term group), or started after 3 years' placebo (cross-over group), denosumab 60 mg sc every 6 months and daily calcium and vitamin D. These data refl ect 5 years' (long-term) or 2 years' (cross-over) continuous denosumab treatment. Effi cacy measures include changes in BMD from extension study baseline and bone turnover markers (BTM). P-values are descriptive.Results: Of the 83.0% of subjects who completed FREEDOM, 70.2% (N = 4550) agreed to participate in the extension (long-term: 2343; cross-over: 2207). In the long-term group, there were further signifi cant gains (P < 0.0001) in BMD in years 4 and 5: 1.9% and 1.7% at the lumbar spine to a total of 13.7% from FREEDOM baseline and 0.7% and 0.6% at the total hip to a total of 7.0%. During their fi rst 2 years' denosumab treatment, women in the cross-over group had signifi cant improvements in lumbar spine (7.9%) and total hip BMD (4.1%) (P < 0.0001). Serum C-telopeptide (CTX) was rapidly reduced following denosumab dosing in both groups, with the characteristic attenuation of CTX reduction observed at the end of the dosing interval. A low incidence of new vertebral and nonvertebral fractures was reported for both groups. The denosumab safety profi le did not change over time.Conclusions: Denosumab treatment for up to 5 years in women with PMO remains well tolerated, maintains reduction of BTMs and continues to significantly increase BMD.Reference1.

Reducing unintentional injuries in and around the home among children under 5 Years

Public Health England today launches 2 new resources for local authorities on preventing accidents to children and young people in the home and on the road. The reports show whilst the number of children and young people killed or seriously injured continues to fall in England there are still significant numbers of deaths and emergency admissions from preventable causes. On average each year between 2008 to 2012, 525 children and young people under 25 died and there were more than 53,700 admissions to hospital. The reports highlight actions local partners can take to reduce accidents including improving safety for children travelling to and from school and using existing services like health visitors and children’s centres. The Reducing unintentional injuries in and around the home among children under 5 Years and the Reducing unintentional injuries on the roads among children and young people under 25 reports include an analysis of data between 2008 to 2012. Key findings from the reports include: home injuries (under 5 years of age): an average of 62 children died each year between 2008 and 2012 these injuries result in an estimated 40,000 emergency hospital admissions among children of this age each year 5 injury types should be prioritised for the under-fives: choking; suffocation and strangulation; falls; poisoning; burns and scalds; and drowning hospital admission rate for unintentional injuries among the under-fives is 45% higher for children from the most deprived areas compared with children from the least deprived Road traffic injuries (under 25 years of age) there were 2,316 deaths recorded by the police among road users under the age of 25 years, an average of 463 under 25s each year there were 68,657 admissions to hospital as a result of road traffic injuries, an average of 13,731 each year in total there were 322,613 casualties of all severities recorded by the police, an average of 64,523 each year the rate of fatal and serious injuries for 10to 14 year olds was significantly greater for children from the 20% most deprived areas (37 per 100,000) compared with those from the most affluent areas (10 per 100,000)

Fuel Poverty and Cold Home-related Health Problems

Evidence Review 7 - Tackling fuel poverty and cold home-related health problems Briefing 7 - Fuel poverty and cold home-related health problems This pair of documents, commissioned by Public Health England, and written by the UCL Institute of Health Equity, address the health impacts of fuel poverty and cold homes. These documents provide an overview of fuel poverty, describing the evidence linking fuel poverty, cold homes, and poor health outcomes. They examine the scale of the problem across England and trends over time. Evidence shows that living in cold homes is associated with poor health outcomes and an increased risk of morbidity and mortality for all age groups. The documents also provide a brief overview of national policy and sets out the role of local authorities and potential interventions at local level. Fuel poverty is not just about poverty, but also about the quality of England’s housing stock and energy efficiency. The review discusses some of the interventions that have been implemented at the local level to help people on low incomes during cold weather and to address cold home-related health problems. The full evidence review and a shorter summary briefing are available to download above. This document is part of a series. An overview document which provides an introduction to this and other documents in the series, and links to the other topic areas, is available on the ‘Local Action on health inequalities’ project page. A video of Michael Marmot introducing the work is also available on our videos page.

Good quality parenting programmes and the home to school transition

Evidence Review 1 - Good quality parenting programmes and the home to school transition Briefing 1a - Good Quality Parenting Programmes Briefing 1b - Improving the Home to School Transition This set of documents, commissioned by Public Health England (PHE£0, and written by the UCL Institute of Health Equity, address the effects of parenting and good transition on the health and wellbeing of children aged 0-5. They also provide case studies, and examples of good practice for local areas. Evaluations from the UK and other countries show a positive effect of parenting interventions on outcomes and behaviours that we know are linked to positive health and development outcomes for children. Home to school transition programmes can be effective in improving the outcomes for children from more disadvantaged socio-economic groups more than for children from more advantaged socio-economic groups, although longer term impact on health inequalities can only be inferred because the impact on health has not been studied. The full evidence review and two shorter summary briefings are available to download above. This document is part of a series. An overview document which provides an introduction to this and other documents in the series, and links to the other topic areas, is available on the ‘Local Action on health inequalities’ project page.

Instrumental leadership: Measurement and extension of transformational-transactional leadership theory.

Leaders must scan the internal and external environment, chart strategic and task objectives, and provide performance feedback. These instrumental leadership (IL) functions go beyond the motivational and quid-pro quo leader behaviors that comprise the full-range-transformational, transactional, and laissez faire-leadership model. In four studies we examined the construct validity of IL. We found evidence for a four-factor IL model that was highly prototypical of good leadership. IL predicted top-level leader emergence controlling for the full-range factors, initiating structure, and consideration. It also explained unique variance in outcomes beyond the full-range factors; the effects of transformational leadership were vastly overstated when IL was omitted from the model. We discuss the importance of a "fuller full-range" leadership theory for theory and practice. We also showcase our methodological contributions regarding corrections for common method variance (i.e., endogeneity) bias using two-stage least squares (2SLS) regression and Monte Carlo split-sample designs.

Home Bitter Home? Gender, Living Arrangements, and the Exclusion from Home-Ownership among Older Europeans

A working paper published by the Families and Societies project shows that older women in non-traditional family arrangements are most disadvantaged with regard to home-ownership. This often appears to result from a lower socio-economic status. Home Bitter Home? Gender, Living Arrangements, and the Exclusion from Home-Ownership among Older EuropeansRead the report here.

The Eukaryotic Promoter Database EPD: the impact of in silico primer extension.

The Eukaryotic Promoter Database (EPD) is an annotated non-redundant collection of eukaryotic POL II promoters, experimentally defined by a transcription start site (TSS). There may be multiple promoter entries for a single gene. The underlying experimental evidence comes from journal articles and, starting from release 73, from 5' ESTs of full-length cDNA clones used for so-called in silico primer extension. Access to promoter sequences is provided by pointers to TSS positions in nucleotide sequence entries. The annotation part of an EPD entry includes a description of the type and source of the initiation site mapping data, links to other biological databases and bibliographic references. EPD is structured in a way that facilitates dynamic extraction of biologically meaningful promoter subsets for comparative sequence analysis. Web-based interfaces have been developed that enable the user to view EPD entries in different formats, to select and extract promoter sequences according to a variety of criteria and to navigate to related databases exploiting different cross-references. Tools for analysing sequence motifs around TSSs defined in EPD are provided by the signal search analysis server. EPD can be accessed at http://www.epd. isb-sib.ch.

Human thymus exports naive CD8 T cells that can home to nonlymphoid tissues.

Functionally naive CD8 T cells in peripheral blood from adult humans can be fully described by their CD45RA(bright)CCR7(+)CD62L(+) cell surface phenotype. Cord blood lymphocytes, from healthy newborns, are homogenously functionally naive. Accordingly, the majority of cord blood CD8 T cells express the same pattern of cell surface molecules. Unexpectedly, however, a significant fraction of cord blood CD8 T cells express neither CCR7 nor CD62L. Yet these cells remain functionally naive as they contain high levels of TCR excision circles, have long telomeres, display highly polyclonal TCRs, and do not exhibit immediate effector functions. In addition, these CD8 T cells already represent a significant fraction of the mature naive CD8 single-positive thymocyte repertoire and may selectively express the cutaneous lymphocyte Ag. We suggest that CD8 single-positive thymocytes comprise two pools of naive precursors that exhibit distinct homing properties. Once seeded in the periphery, naive CCR7(+)CD62L(+) CD8 T cells patrol secondary lymphoid organs, whereas naive CCR7(-)CD62L(-) CD8 T cells selectively migrate to peripheral tissues such as skin.
