[Quality criteria for health promotion and primary prevention measures in association with obesity in children and adolescents. A BZgA-coordinated expert consensus]

On behalf of the Federal Ministry of Health, a working group coordinated by the Federal Center for Health Education (BZgA) compiled quality criteria for health promotion and primary prevention measures in association with obesity in children and adolescents that are applicable both to population-wide and to target group-specific measures. The criteria are intended to support the planning of new measures and the conceptual improvement of existing measures. Additional elements are the assessment of programs for financing purposes and the rendering of accounts to funding agencies, as well as the acquisition of further knowledge. The criteria, thus, address not only project developers and providers, but also multipliers who implement measures, as well as funding agencies, who can use the criteria as a basis for assessing the measures. The structure of the quality criteria is geared to the fundamental structure of the Public Health Action Cycle. In addition, resource orientation, participation and, above all, organizational development are important aspects associated with quality that have not been given adequate consideration to date. The quality criteria are applicable to all situation-based and behavioral prevention measures, and also development processes that focus on promoting the health and normal weight development of children and adolescents.

Leukoencephalomalacia and Laminar Neuronal Necrosis Following Smoke Inhalation in a Dog

Acute respiratory and neurologic disease after smoke inhalation are well documented, but human patients may also develop delayed-onset neurologic symptoms associated with leukoencephalomalacia after exposure to smoke or carbon monoxide. In this case, a dog developed progressive neurologic signs 6 days after rescue from an apartment fire. At necropsy 9 days after smoke inhalation, leukoencephalomalacia of the central cerebral white matter was accompanied by laminar necrosis of cerebrocortical neurons. This is the first report of delayed posthypoxic leukoencephalopathy in a nonhuman animal.

How to search and harvest the medical literature: let the citations come to you, and how to proceed when they do

BACKGROUND

There is a virtual avalanche of medical information available to clinicians and researchers. The traditional 'search' can be substantially augmented by proactive 'harvesting.'

AIMS

To describe how to search and harvest the medical literature.

MATERIALS & METHODS

Survey of selected resources available on the internet.

RESULTS

PubMed remains the backbone of the traditional literature search. The availability of automated delivery of electronic tables of contents ('eTOCs'), electronic feeds of targeted search results, and workflow tools allows relevant articles to find the reader. Electronic storage and retrieval tools make it possible to manage this information and make day-to-day clinical and research activities more efficient.

DISCUSSION

Searching and harvesting the medical literature is made easier with the advent of the internet and email. In addition, there are internet resources that screen and filter potential articles of interest. Managing one's electronic library of PDF documents requires attention to appropriately naming files and the use of indexing programs.

CONCLUSION

In addition to readers searching for relevant citations, these citations themselves can be searching for readers. Clinicians and researchers can take advantage of this and efficiently harvest the medical literature with a modest investment of time.

Science journal editors' views on publication ethics: results of an international survey

BACKGROUND

Breaches of publication ethics such as plagiarism, data fabrication and redundant publication are recognised as forms of research misconduct that can undermine the scientific literature. We surveyed journal editors to determine their views about a range of publication ethics issues.

METHODS

Questionnaire sent to 524 editors-in-chief of Wiley-Blackwell science journals asking about the severity and frequency of 16 ethical issues at their journals, their confidence in handling such issues, and their awareness and use of guidelines.

RESULTS

Responses were obtained from 231 editors (44%), of whom 48% edited healthcare journals. The general level of concern about the 16 issues was low, with mean severity scores of <1 (on a scale of 0-3) for all but one. The issue of greatest concern (mean score 1.19) was redundant publication. Most editors felt confident in handling the issues, with <15% feeling "not at all confident" for all but one of the issues (gift authorship, 22% not confident). Most editors believed such problems occurred less than once a year and >20% of the editors stated that 12 of the 16 items never occurred at their journal. However, 13%-47% did not know the frequency of the problems. Awareness and use of guidelines was generally low. Most editors were unaware of all except other journals' instructions.

CONCLUSIONS

Most editors of science journals seem not very concerned about publication ethics and believe that misconduct occurs only rarely in their journals. Many editors are unfamiliar with available guidelines but would welcome more guidance or training.

[Efficacy and safety of probiotics]

Probiotics are bacteria or fungi, which modulate pathogenic growth and invasion of the bowel. The most frequently used are Lactobacillus and Saccharomyces cerevisiae. They are widely used as dietary supplements or for the treatment and prevention of various types of diarrhoea. Probiotics are generally considered as safe, but some cases of invasive infections have been described in different patient populations. This article reviews the literature about the indications and risks of probiotics, especially in immunocompromised patients.

Long-term endurance exercise decreases antiangiogenic endostatin signalling in overweight men aged 50-60 years

BACKGROUND

Endurance training may decrease the risk of coronary artery disease. It has been speculated that these effects may be due to an exercise-induced stimulation of angiogenesis. The underlying mechanisms are not yet clear. Therefore, using ELISA, we investigated the plasma level of vascular endothelial growth factor (VEGF, angiogenic factor) and endostatin (antiangiogenic factor) in a group of untrained men aged 50-60 years with obesity.

METHODS

All men were randomised into a "running" group (training 3 times/week, 60 min each, n = 7), a "cycling" group ( training 3 times/week, 90 min each, n = 7) and a sedentary control group ( n = 7). Both training groups worked at moderate intensity (2-4 mmol/l lactate). The intervention had a duration of 6 months. Before and after this period, blood samples were taken from the participants at rest and they underwent a medical investigation.

RESULTS

Body mass index (BMI), systolic and diastolic blood pressure, and plasma levels of VEGF and endostatin were comparable in all three groups. Endurance training significantly reduced BMI in both exercise groups (mean (SEM) before v after 29.7 (0.7) v 29.1 (0.6) kg/m2 and 31.1 (0.7) v 30.1 (0.9) kg/m2 for the running and cycling groups respectively) but not in the control group (30.0 (1.0) v 30.2 (0.8) kg/m2). Endurance training did not influence VEGF plasma level (before v after 1.3 (0.4) v 1.5 (0.2) ng/ml for the running group; 1.6 (0.3) v 1.5 (0.2) ng/ml for the cycling group; and 2.5 (0.6) v 2.1 (0.7) ng/ml for the control group). Plasma level of endostatin was significantly reduced in both exercise groups (mean (SEM) before v after: 20.9 (1.6 v 17.5 (1.0) ng/ml and 21.3 (1.4 v 18.0 (1.6) ng/ml for the running and cycling groups respectively) but not in controls (19.7 (1.3 v 17.7 (1.1 ng/ml).

CONCLUSIONS

Endurance training may reduce the antiangiogenic mechanisms in men aged 50-60 years by reducing endostatin plasma level and this may subsequently decrease the risk of cardiovascular disease.

Accrual of organ damage over time in Argentine patients with systemic lupus erythematosus: a multi-centre study

The goals of this study were to ascertain damage in patients with systemic lupus erythematosus (SLE) from five rheumatologic centres in Argentina and to examine overall damage, damage by domain and damage by item within each domain. We performed a retrospective observational study including patients with SLE (ACR 1997 revised and modified criteria) from five rheumatology centres in Argentina. Organ damage was scored using the SLICC/ACR DI (SDI), ascertained at years 1, 2, 5 and 10. Three centres provided information up to the fifth year. Of the 197 patients, 88.3% were women and their mean age was 33.2 years. The mean disease duration and follow-up were 7.6 and 5.3 years, respectively. Damage accrued gradually over time with SDI ranging from 0.52 (+/-1.1) at year 1 up to 2.46 (+/-2.1) at year 10. The renal system was the most involved system, followed by the neuropsychiatric, the cardiovascular and the musculoskeletal systems. Proteinuria, cognitive impairment, pericarditis, avascular necrosis, cataract and alopecia were the predominant items in their respective systems. Systems such as peripheral vascular, pulmonary, gastrointestinal, diabetes, malignancy and premature gonadal failure were not frequent. Overall SDI had a gradual increase over time. Damage in each domain of SDI, except for diabetes, had a similar behaviour. Behaviour of items in each domain varied.
