[Show abstract][Hide abstract] ABSTRACT: This paper presents the results of a global survey that aimed to collect information on country's immunization policy development processes, particularly on the presence and function of national Immunization Technical Advisory Groups (ITAGs). Characteristics of national ITAGs are described as well as attributes of these groups that appear to be imperative for an effective ITAG. ITAGs provide a valued service to over 89 countries that reported their establishment, some of which have been in existence for over 40 years. This paper provides basic information on the functioning of these groups and encourages future efforts to address gaps in knowledge and research in this area.
[Show abstract][Hide abstract] ABSTRACT: This systematic review aimed to collect and synthesize information available on immunization policy making processes in countries across the globe. Twenty-nine published articles and five websites in either English or French provided varied information on the immunization policy making processes in 33 countries. The information retrieved varied from players involved to types of evidence used when making immunization policies. Fourteen countries reported the presence of a National Immunization Technical Advisory Group (NITAG), an advisory body that provides immunization recommendations to the national government to facilitate their policy making. In conclusion, there is relatively limited information available on immunization policy making processes at the national level.
[Show abstract][Hide abstract] ABSTRACT: This paper reports the results of a global survey on the topic of national immunization policy development. Countries reported on actors involved, sources of evidence consulted, challenges faced and desired changes in their immunization policy development processes. Most countries had established or would like to establish a national Immunization Technical Advisory Group (ITAG). Countries reported using many sources of information; the most valued being those from the World Health Organization (WHO). Common challenges of immunization policy development reported include funding, capturing the epidemiology of disease and coordination of government and stakeholders.

[Show abstract][Hide abstract] ABSTRACT: The effect of practicing yoga for the management of type II Diabetes was assessed in this systematic review through searching related electronic databases and the grey literature to the end of May 2007 using Ovid. All randomized controlled clinical trials (RCTs) comparing yoga practice with other type of intervention or with regular practice or both, were included regardless of language or type of publication. Each study was assessed for quality by two independent reviewers. Mean difference was used for summarizing the effect of each study outcomes with 95% confidence intervals. Pooling of the studies did not take place due to the wide clinical variation between the studies. Publication bias was assessed by statistical methods. Five trials with 363 participants met the inclusion criteria with medium to high risk of bias and different intervention characteristics. The studies' results show improvement in outcomes among patients with diabetes type II. These improvements were mainly among short term or immediate diabetes outcomes and not all were statistically significant. The results were inconclusive and not significant for the long-term outcomes. No adverse effects were reported in any of the included studies. Short-term benefits for patients with diabetes may be achieved from practicing yoga. Further research is needed in this area. Factors like quality of the trials and other methodological issues should be improved by large randomized control trials with allocation concealment to assess the effectiveness of yoga on diabetes type II. A definitive recommendation for physicians to encourage their patients to practice yoga cannot be reached at present.
