- BACKGROUND: The Global Burden of Disease, Injuries, and Risk Factor study 2013 (GBD 2013) is the first of a series of annual updates of the GBD. Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution.METHODS: Attributable deaths, years of life lost, years lived with disability, and disability-adjusted life-years (DALYs) have been estimated for 79 risks or clusters of risks using the GBD 2010 methods. Risk-outcome pairs meeting explicit evidence criteria were assessed for 188 countries for the period 1990-2013 by age and sex using three inputs: risk exposure, relative risks, and the theoretical minimum risk exposure level (TMREL). Risks are organised into a hierarchy with blocks of behavioural, environmental and occupational, and metabolic risks at the first level of the hierarchy. The next level in the hierarchy includes nine clusters of related risks and two individual risks, with more detail provided at levels 3 and 4 of the hierarchy. Compared with GBD 2010, six new risk factors have been added: handwashing practices, occupational exposure to trichloroethylene, childhood wasting, childhood stunting, unsafe sex, and low glomerular filtration rate. For most risks, data for exposure were synthesised with a Bayesian meta-regression method, DisMod-MR 2.0, or spatial-temporal Gaussian process regression. Relative risks were based on meta-regressions of published cohort and intervention studies. Attributable burden for clusters of risks and all risks combined took into account evidence on the mediation of some risks such as high body-mass index (BMI) through other risks such as high systolic blood pressure and high cholesterol.FINDINGS: All risks combined account for 57·2% (95% uncertainty interval [UI] 55·8-58·5) of deaths and 41·6% (40·1-43·0) of DALYs. Risks quantified account for 87·9% (86·5-89·3) of cardiovascular disease DALYs, ranging to a low of 0% for neonatal disorders and neglected tropical diseases and malaria. In terms of global DALYs in 2013, six risks or clusters of risks each caused more than 5% of DALYs: dietary risks accounting for 11·3 million deaths and 241·4 million DALYs, high systolic blood pressure for 10·4 million deaths and 208·1 million DALYs, child and maternal malnutrition for 1·7 million deaths and 176·9 million DALYs, tobacco smoke for 6·1 million deaths and 143·5 million DALYs, air pollution for 5·5 million deaths and 141·5 million DALYs, and high BMI for 4·4 million deaths and 134·0 million DALYs. Risk factor patterns vary across regions and countries and with time. In sub-Saharan Africa, the leading risk factors are child and maternal malnutrition, unsafe sex, and unsafe water, sanitation, and handwashing. In women, in nearly all countries in the Americas, north Africa, and the Middle East, and in many other high-income countries, high BMI is the leading risk factor, with high systolic blood pressure as the leading risk in most of Central and Eastern Europe and south and east Asia. For men, high systolic blood pressure or tobacco use are the leading risks in nearly all high-income countries, in north Africa and the Middle East, Europe, and Asia. For men and women, unsafe sex is the leading risk in a corridor from Kenya to South Africa.INTERPRETATION: Behavioural, environmental and occupational, and metabolic risks can explain half of global mortality and more than one-third of global DALYs providing many opportunities for prevention. Of the larger risks, the attributable burden of high BMI has increased in the past 23 years. In view of the prominence of behavioural risk factors, behavioural and social science research on interventions for these risks should be strengthened. Many prevention and primary care policy options are available now to act on key risks.FUNDING: Bill & Melinda Gates Foundation.

- Background/Aims: Validation of treatments with individually prescribed homeopathic medicines is a challenging task. A prognostic homeopathic patient questionnaire containing 140 keynote symptoms (highly characteristic of a specific homeopathic medicine) and an electronic algorithm to process the answers were used in 2 clinical studies. The algorithm outcome, based on total symptom scores, indicated 1 of 11 pre-selected homeopathic medicines for women with premenstrual syndrome and premenstrual dysphoric disorder (PMS/PMDD). Aims were (1) to estimate the prognostic values of keynote symptoms and (2) to evaluate the reliability of the homeopathic medicine ranking in the algorithm outcome.Methods: The prevalence of specific keynote symptoms was calculated in 145 women diagnosed with PMS/PMDD and in 40 included women with favorable outcomes using 1 of the 11 homeopathic medicines. Likelihood ratios (LRs) of the keynote symptoms were calculated. Pearson's correlations were calculated between 2 sets of total algorithm scores for 11 homeopathic medicines, obtained at 2 time points.Results: (1) A positive prognostic value (LR >= 1.5) was found in 34 keynote symptoms with a prevalence of 10-40%, with 10 symptoms already being connected to the corresponding homeopathic medicine in the algorithm. For example, the symptom 'common cold of the nose before menstruation' indicated Magnesium carbonicum with LR = 7.47 (confidence interval (CI) 3.90-14.28). (2) Pearson's correlations for the reliability evaluation varied from 0.69 to 0.84.Conclusions: Recommendations can be made to improve the PMS algorithm with more accurate keynote symptoms. The prognostic questionnaire proved a reliable tool to rank 11 homeopathic medicines by total scores, based on keynote symptoms. This PMS algorithm can be used for the treatment of PMS/PMDD in clinical practice.

- OBJECTIVES: Premenstrual syndrome and premenstrual dysphoric disorder (PMS/PMDD) bother a substantial number of women. Homeopathy seems a promising treatment, but it needs investigation using reliable study designs. The feasibility of organizing an international randomized pragmatic trial on a homeopathic add-on treatment (usual care [UC] + HT) compared with UC alone was evaluated.DESIGN: A multicenter, randomized, controlled pragmatic trial with parallel groups.SETTINGS/LOCATION: The study was organized in general and private homeopathic practices in the Netherlands and Sweden and in an outpatient university clinic in Germany.SUBJECTS: Women diagnosed as having PMS/PMDD, based on prospective daily rating by the daily record of severity of problems (DRSP) during a period of 2 months, were included and randomized.INTERVENTIONS: Women were to receive UC + HT or UC for 4 months. Homeopathic medicine selection was according to a previously tested prognostic questionnaire and electronic algorithm. Usual care was as provided by the women's general practitioner according to their preferences.OUTCOME MEASURES: Before and after treatment, the women completed diaries (DRSP), the measure yourself concerns and well-being, and other questionnaires. Intention-to-treat (ITT) and per protocol (PP) analyses were performed.RESULTS: In Germany, the study could not proceed because of legal limitations. In Sweden, recruitment proved extremely difficult. In the Netherlands and Sweden, 60 women were randomized (UC + HT: 28; UC: 32), data of 47/46 women were analyzed (ITT/PP). After 4 months, relative mean change of DRSP scores in the UC + HT group was significantly better than in the UC group (p = 0.03).CONCLUSIONS: With respect to recruitment and different legal status, it does not seem feasible to perform a larger, international, pragmatic randomized trial on (semi-)individualized homeopathy for PMS/PMDD. Since the added value of HT compared with UC was demonstrated by significant differences in symptom score changes, further studies are warranted.

- BACKGROUND: In order to further improve the methodology and quality of data collection in homeopathic drug provings (HDP), there is a need for a minimum standardised HDP protocol. The objective of the present study was to test the feasibility of this type of protocol.MATERIALS AND METHODS: The study protocol embraced a multi-centre, randomised, double-blind, placebo-controlled trial with 2 parallel groups. It was approved by an ethics review committee. During the pre-approval phase, discordances between the regulatory and homeopathic requirements for the protocol were checked and solutions found. The study medication was Potentilla anserina. 6 participants received verum and 4 placebo. The resulting symptom list will be published elsewhere. The procedure was accepted by all participants.RESULTS: Three important issues were addressed: the requirement to keep all participants blinded; the adverse events reporting to regulatory authorities; and the necessity of a placebo control group. Other issues that need further investigations were identified, e.g. sample size, observation period and dosage regimen.CONCLUSIONS: A minimum protocol of a HDP is feasible. All important design elements of HDP could be solved in discussions with the respective regulatory authorities, and participating homeopaths accepted the procedure.
