Look beyond financial conflicts of interest in evaluating industry-academia collaborations in burden-of-illness and outcomes research studies in dermatology.
(41/422)
Financial relationships exist among industry, scientific investigators, and academic medical centers. These relationships can foster research in the basic sciences, clinical trials, health economics evaluations, and other outcomes assessment studies. To govern the conduct of burden-of-illness and outcomes research studies involving collaborations between industry and academia, we propose voluntary standards related to: 1) the development of and adherence to standards for research conduct and reporting; 2) disclosure, discussion, and management of potential impacts of financial conflicts of interest; and 3) transparency in research methods and open access to study results.

The role of mentoring relationships in the career development of successful deaf persons.
(42/422)
A qualitative study of deaf graduates of Rochester Institute of Technology in New York State who became supervisors in primarily hearing work settings found that having a mentor was a primary and persistent element in their career success. In the deaf individual's early years, generally it was a family member or teacher who conveyed a belief in that individual's abilities, encouraged effort, and helped instill self-esteem and confidence. Parents were often their strongest advocates, and teachers were their advisors and facilitators. In the work setting, a supervisor or coworker often served as a mentor by coaching, advising, and teaching the individual what they needed to know to succeed on the job. In many ways, these "informal" mentors provided the foundation that enabled the deaf individual to break through what are often barriers to career success despite their skills and abilities. The various forms of mentorship and their impact on deaf college graduates are explored. (+info)
Unusual manifestations of infections due to Mycoplasma pneumoniae in children.
(43/422)
Mycoplasma pneumoniae (Mp) is an important cause of pneumonia in paediatric age, but also other organs or systems can be affected even without pulmonary involvement. The purpose of this study is to stress the unusual clinical features of Mp infection in children. A review of children affected with Mp infection with peculiar pulmonary and/or extra-pulmonary forms is reported. Diagnosis of Mp infection was always confirmed by serum anti-Mp antibody assay. Two patients with infection of the lower airways showed severe respiratory distress; nine cases with only extra-pulmonary manifestations presented urticaria and arthralgia; three patients had severe neuromuscular impairment, one of these resulting in flaccid tetraparesis; one 2-year-old child had anicteric hepatitis, without any sequelae; one case of a 6-year-old child presented severe haemolytic anaemia, and a 5-year-old child with Schonlein-Henoch purpura. In conclusion, Mp infection, a frequent cause of pneumonia at all paediatric ages, may also give rise to extrapulmonary manifestations. Frequently, muscular-articular or neurological systems, skin or other organs are involved. Clinical suspicion of Mp infection is essential in severe cases and the outcome of all pulmonary and/or extra-pulmonary manifestations depends on early diagnosis and specific therapy. (+info)
Assessing precollege science education outreach initiatives: a funder's perspective.
(44/422)
We describe an assessment of the collective impact of 35 grants that the Howard Hughes Medical Institute (HHMI) made to biomedical research institutions in 1999 to support precollege science education outreach programs. Data collected from funded institutions were compared with data from a control group of institutions that had advanced to the last stage of review but had not been funded. The survey instrument and the results reveal outcomes and impacts that HHMI considers relevant for these programs. The following attributes are considered: ability to secure additional, non-HHMI funding; institution buy-in as measured by gains in dedicated space and staff; enhancement of the program director's career; number and adoption of educational products developed; number of related publications and awards; percentage of programs for which teachers received course credit; increase in science content knowledge; and increase in student motivation to study science.

The lack of public health research output from India.
(45/422)
BACKGROUND: Systematic assessment of recent health research output from India, and its relation with the estimated disease burden, is not available. This information would help understand the areas in health research that need improvement in India to enhance the health of India's population. METHODS: The health research output from India during 2002, which was accessible in the public domain, was assessed by searching PubMed and other internet health literature databases, and was related to the disease burden suggested by the Global Burden of Disease Study. The main outcome measures were number of health papers with abstracts in basic, clinical and public health sciences; quality-adjusted research output based on the impact factors of journals in which the papers were published; classification of papers in disease/condition categories and comparison of research output with the estimated disease burden in each category. Comparison of the health papers from India during 2002 included in PubMed was done with those from Australia during one quarter of 2002. RESULTS: Of the 4876 health papers from India in 2002 in PubMed, 48.4%, 47.1% and 4.4% were in basic, clinical and public health sciences, respectively. Of the 4495 papers based on original research, only 3.3% were in public health. Quality-adjusted original research output was highest for non-communicable diseases (62% of total). Of the total quality-adjusted original research output, the proportions in injuries (0.7%), cardiovascular diseases (3.6%), respiratory infections (0.2%), diarrhoeal diseases (1.9%), perinatal conditions (0.4%), childhood cluster diseases (0.5%), unipolar major depression (0%), and HIV/AIDS (1.5%) were substantially lower than their proportional contribution to the disease burden in India. Human resources, health policy, health economics, and impact assessment of interventions were particularly poorly represented in public health research. The Australia-India ratio for quality-adjusted health research output per unit gross domestic product was 20 and for public health research output was 31. CONCLUSIONS: Good-quality public health research output from India is grossly inadequate, and strategic planning to improve it is necessary if substantial enhancement of population health were to be made possible. There is inordinately low relative research output in several diseases/conditions that cause major disease burden in India. (+info)
Do the findings of case series studies vary significantly according to methodological characteristics?
(46/422)
OBJECTIVES: To review the use of case series in National Institute for Clinical Excellence (NICE) Health Technology Assessment (HTA) reports, to review systematically the methodological literature for papers relating to the validity of aspects of case series design, and to investigate characteristics and findings of case series using examples from the UK's Health Technology Assessment programme. DATA SOURCES: Electronic databases. NICE website. Reports produced as part of the UK's HTA programme. REVIEW METHODS: NICE HTAs that used information from case series studies were obtained from the NICE website and a range of quality criteria applied. Searches of electronic databases, handsearched journals and the bibliographies of papers were made in order to find studies that assessed aspects of case series design, analysis or quality in relation to study validity. Hypotheses relating to the design of case series studies were developed and empirically investigated using four case examples from existing reports produced as part of the UK's HTA programme (functional endoscopic sinus surgery for nasal polyps, spinal cord stimulation for chronic back pain, percutaneous transluminal coronary angioplasty and coronary artery bypass grafting for chronic angina). Analysis was undertaken comparing studies within each review. RESULTS: There was no consensus on which case series to include in HTAs, how to use them or how to assess their quality, despite them being used in 30% of NICE HTAs. No previous studies empirically investigating methodological characteristics of case series were found. However, it is possible that the search strategy failed to find relevant studies. Poor reporting of case series characteristics severely constrained analysis and there were insufficient data to investigate all the hypotheses. Findings were not consistent across the different topics and were subject to considerable uncertainty. All the examples in our analysis were surgical interventions, which are prone to additional confounding factors due to difficulties of standardisation compared with drug treatment. Our findings may not be generalisable outside the interventions studied. The case series reports included generally exhibited poor reporting of methodological characteristics. This constrained our analysis. The use of several methods of analysis has led to apparently discrepant results. Given the number of analysis performed, the usual level of significance (p = 0.05) should be viewed with caution. The most important limitation of this study is the small number of cases on which the findings are based. The results are therefore tentative and should be viewed with caution. CONCLUSIONS: Case series are incorporated in a significant proportion of health technology assessments. Quality criteria have been used to appraise the quality of case series and decide on their inclusion in reviews of studies using this design. In this small series of case studies drawn from HTAs carried out for the NHS HTA programme, little evidence was found to support the use of many of the factors included in quality assessment tools. Importantly, no relationship was found between study size and outcome across the four examples studied. Isolated examples of a potentially important relationship between other methodological factors and outcome were shown, such as blinding of outcome measurement, but these were not shown consistently across the small number of examples studied. This study is based on a very small sample of studies and should therefore be considered as exploratory. Further investigation of the relationship between methodological features and outcome is justified given the frequency of use of case series in health technology assessments. Further research into the methodological features of case series and their outcome is justified in a wider sample of technologies and larger sets of case series. Value of information analyses including case series could be explored. Further exploration of the differences between case series and randomised controlled trial results, preferably using registry or comprehensive case series data, would be valuable. (+info)
Comparing estimates of cost effectiveness submitted to the National Institute for Clinical Excellence (NICE) by different organisations: retrospective study.
(47/422)
OBJECTIVE: To assess the association between different types of organisation and the results from economic evaluations. DESIGN: Retrospective pairwise comparison of evidence submitted to the technology appraisal programme of the National Institute for Clinical Excellence (NICE) by manufacturers of the relevant healthcare technologies and by contracted university based assessment groups. DATA SOURCES: Data from the first 62 appraisals. MAIN OUTCOME MEASURE: Incremental cost effectiveness ratios. RESULTS: Data from 27 of the 62 appraisals could be compared. The analysis of 54 pairwise comparisons showed that manufacturers' estimates of incremental cost effectiveness ratios were lower (suggesting a more cost effective use of resources) than those produced by the assessment groups (25 were lower, 29 were the same, none were higher, P < 0.01). Restriction of this dataset to include only one pairwise comparison per appraisal (27 pairs) produced a similar result (21 were lower, two were the same, four were higher, P < 0.001). CONCLUSIONS: The estimated incremental cost effectiveness ratios submitted by manufacturers were on average significantly lower than those submitted by the assessment groups. These results show that an important role of NICE's appraisal committee, and of decision makers in general, is to determine which economic evaluations, or parts of evaluations, should be given more credence.

Building capacity in health research in the developing world.
(48/422)
Strong national health research systems are needed to improve health systems and attain better health. For developing countries to indigenize health research systems, it is essential to build research capacity. We review the positive features and weaknesses of various approaches to capacity building, emphasizing that complementary approaches to human resource development work best in the context of a systems and long-term perspective. As a key element of capacity building, countries must also address issues related to the enabling environment, in particular: leadership, career structure, critical mass, infrastructure, information access and interfaces between research producers and users. The success of efforts to build capacity in developing countries will ultimately depend on political will and credibility, adequate financing, and a responsive capacity-building plan that is based on a thorough situational analysis of the resources needed for health research and the inequities and gaps in health care. Greater national and international investment in capacity building in developing countries has the greatest potential for securing dynamic and agile knowledge systems that can deliver better health and equity, now and in the future.
