Deferasirox (Exjade®) significantly improves cardiac T2* in heavily iron-overloaded patients with β-thalassemia major
No full textNoninvasive measurement of tissue iron levels can be assessed using T2* magnetic resonance imaging (MRI) to identify and monitor patients with iron overload. This study monitored cardiac siderosis using T2* MRI in a cohort of 19 heavily iron-overloaded patients with β-thalassemia major receiving iron chelation therapy with deferasirox over an 18-month period. Overall, deferasirox therapy significantly improved mean ± standard deviation cardiac T2* from a baseline of 17.2±10.8 to 21.5±12.8 ms (+25.0percent; P=0.02). A concomitant reduction in median serum ferritin from a baseline of 5,497 to 4,235 ng-mL (-23.0percent; P=0.001), and mean liver iron concentration from 24.2±9.0 to 17.6± 12.9 mg Fe-g dry weight (-27.1percent; P=0.01) was also seen. Improvements were seen in patients with various degrees of cardiac siderosis, including those patients with a baseline cardiac T2* of 10 ms, indicative of high cardiac iron burden. These findings therefore support previous observations that deferasirox is effective in the removal of myocardial iron with concomitant reduction in total body iron. © The Author(s) 2009.Anderson LJ, 2006, ACTA HAEMATOL-BASEL, V115, P106, DOI 10.1159-000089475; Anderson LJ, 2001, EUR HEART J, V22, P2171, DOI 10.1053-euhj.2001.2822; Borgna-Pignatti C, 2004, HAEMATOLOGICA, V89, P1187; BRITTENHAM GM, 1994, NEW ENGL J MED, V331, P567, DOI 10.1056-NEJM199409013310902; Cappellini MD, 2006, BLOOD, V107, P3455, DOI 10.1182-blood-2005-08-3430; Daar S, 2009, HAEMATOL-HEMATOL J, V94, P140, DOI 10.3324-haematol.13845; ELEFTHERIOU P, 2006, HAEMATOLOGICA S1, V91, P999; Garbowski M, 2008, BLOOD, V112, P116; Kolnagou A, 2006, HEMOGLOBIN, V30, P219, DOI 10.1080-03630260600642542; Noetzli LJ, 2008, BLOOD, V112, P2973, DOI 10.1182-blood-2008-04-148767; PENNELL D, 2008, BLOOD, V112, P3874; Pennell DJ, 2008, BLOOD, V112, P3873; Porter J, 2008, EUR J HAEMATOL, V80, P168, DOI 10.1111-j.1600-0609.2007.00985.x; St Pierre TG, 2005, BLOOD, V105, P855, DOI 10.1182-blood-2004-01-0177; Taher A, 2009, EUR J HAEMATOL, V82, P458, DOI 10.1111-j.1600-0609.2009.01228.x; Vichinsky E, 2007, BRIT J HAEMATOL, V136, P501, DOI 10.1111-j.1365-2141.2006.06455.x; Westwood M, 2003, J MAGN RESON IMAGING, V18, P33, DOI 10.1002-jmri.10332; Wood JC, 2004, BLOOD, V104, p111A; Wood JC, 2008, BLOOD, V112, P3882; Wood JC, 2006, TRANSL RES, V148, P272, DOI 10.1016-j.trsl.2006.05.005; ZURLO MG, 1989, LANCET, V2, P2719222
Prevalence and experience of harassment of people with mental health problems living in the community
No full text<i>Declaration</i> <i>of</i> <i>interest</i>: This study was funded by the Communities Fund and was the result of a partnership between the Nuffield Centre for Community Care Studies, University of Glasgow, the National Schizophrenia Fellowship (Scotland) and the Scottish users' network.
<i>Background</i>: The levels and experiences of harassment of people with mental health problems in the community compared with those of the general population have not been explored.
<i>Aims</i>: To measure the levels and experience of harassment experienced by people with mental health problems in the community in Scotland and compare them with the general population.
<i>Method</i>: Experiences of harassment were collected by interviewing 165 individuals with mental health problems and a control group of 165 people from the general population.
<i>Results</i>: Harassment in the community was found to be twice as common for individuals with mental health problems (41%) than for those in the general population (15%). The harassment commonly involved verbal abuse referring to the individual's mental health problems and was committed primarily by teenagers and neighbours.
<i>Conclusions</i>: Harassment has a significantly higher prevalence among individuals with mental health problems living in the community and is believed to have a detrimental effect on mental health
HGV-HCV/HBV co-infection in India: A pilot study
No full textBackground: Hepatitis G virus (HGV) is newly identified virus, transmitted by infected blood and blood products. Effect of HGV infection on liver diseases is not well known. Aims: Co-infection of HGV with hepatitis B virus (HBV) and hepatitis C virus (HCV) infection has been reported however; very limited data is available from India. Therefore, we have performed a pilot study for the presence of co-infection of HGV in chronic liver disease patients. Setting and Design: The study was performed in research laboratory at P.D. Hinduja National hospital and Medical research center, Mahim, Mumbai. Prospective study was designed. Methods and Materials: Forty HBV, HCV related chronic liver disease patients were studied. Forty randomly selected voluntary healthy blood donors visiting our blood bank were included as controls. Serum bilirubin, alanine aminotransferase (ALT), Aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were estimated. HGV infection was detected by using reverse transcriptase molony murine leukemia virus (M-MLV) with the help of HGV 340/625IC kit (Sacace, Italy). Results and Conclusion: One HCV positive patient had infection with HGV among 40 HBV/HCV chronic liver disease patients
A review of mental health policies from Commonwealth countries
No full textBackground: The burden of disease related to mental disorders across the world is substantial. However, there remains inequality between funding for clinical and research activities between physical illness and mental illness in almost all countries. Aims: One way of reducing this inequality is to ensure that mental health policies reflect this. We were interested in looking at the policies of members of Commonwealth. Method: We decided to survey 52 member countries of the Commonwealth to explore whether mental health policies existed and whether there was equity between physical and mental health services funding. Using World Health Organization (WHO) data sets and other sources when indicated, we looked at the existence and contents of mental health policies. Results: We found that less than half of the countries had a mental health policy. Deinstitutionalization was not seen as a priority in many countries and there was no equity between physical and mental health funding. Although integration between physical and mental health care was recommended in many countries, there was a clear gap. Conclusion: It is apparent that there is still a long way to go in terms of equity between physical and mental health in terms of funding in member states of the Commonwealth. These findings confirm earlier observations of discrimination against people with mental illness. We suggest that there must be mechanisms in place to facilitate and support change wherever required

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
G-Rank: Unsupervised Continuous Learn-to-Rank for Edge Devices in a P2P Network
No full textRanking algorithms in traditional search engines are powered by enormous training data sets that are meticulously engineered and curated by a centralized entity. Decentralized peer-to-peer (p2p) networks such as torrenting applications and Web3 protocols deliberately eschew centralized databases and computational architectures when designing services and features. As such, robust search-and-rank algorithms designed for such domains must be engineered specifically for decentralized networks, and must be lightweight enough to operate on consumer-grade personal devices such as a smartphone or laptop computer. We introduce G-Rank, an unsupervised ranking algorithm designed exclusively for decentralized networks. We demonstrate that accurate, relevant ranking results can be achieved in fully decentralized networks without any centralized data aggregation, feature engineering, or model training. Furthermore, we show that such results are obtainable with minimal data preprocessing and computational overhead, and can still return highly relevant results even when a user’s device is disconnected from the network. G-Rank is highly modular in design, is not limited to categorical data, and can be implemented in a variety of domains with minimal modification. The results herein show that unsupervised ranking models designed for decentralized p2p networks are not only viable, but worthy of further research.https://github.com/awrgold/G-RankComputer Scienc
