Review Meta AnalysisEffect of administration of antihelminthics for soil transmitted helminths during pregnancy.
Helminthiasis is infestation of the human body with parasitic worms and it is estimated to affect 44 million pregnancies, globally, each year. Intestinal helminthiasis is associated with blood loss and decreased supply of nutrients for erythropoiesis, resulting in iron deficiency anaemia. Over 50% of the pregnant women in low- and middle-income countries suffer from iron deficiency anaemia. Though iron deficiency anaemia is multifactorial, hook worm infestation is a major contributory cause in women of reproductive age in endemic areas. Antihelminthics are highly efficacious in treating hook worm but evidence of their beneficial effect and safety, when given during pregnancy, has not been established. ⋯ The evidence to date is insufficient to recommend use of antihelminthics for pregnant women after the first trimester of pregnancy. More well-designed, large scale randomised controlled trials are needed to establish the benefit of antihelminthic treatment during pregnancy.

Review Meta AnalysisIntercessory prayer for the alleviation of ill health.
Prayer is amongst the oldest and most widespread interventions used with the intention of alleviating illness and promoting good health. Given the significance of this response to illness for a large proportion of the world's population, there has been considerable interest in recent years in measuring the efficacy of intercessory prayer for the alleviation of ill health in a scientifically rigorous fashion. The question of whether this may contribute towards proving or disproving the existence of God is a philosophical question lying outside the scope of this review of the effects of prayer. This revised version of the review has been prepared in response to feedback and to reflect new methods in the conduct and presentation of Cochrane reviews. ⋯ These findings are equivocal and, although some of the results of individual studies suggest a positive effect of intercessory prayer,the majority do not and the evidence does not support a recommendation either in favour or against the use of intercessory prayer. We are not convinced that further trials of this intervention should be undertaken and would prefer to see any resources available for such a trial used to investigate other questions in health care.

ReviewInterventions for improving the psychosocial well-being of children affected by HIV and AIDS.
As a result of HIV-related mortalities more than 13 million children under the age of 15 have lost a parent due to HIV and AIDS. There are also many children who have HIV-positive parents or primary caregivers; these children are affected by HIV and AIDS and are potentially vulnerable to HIV transmission. Children affected by HIV and AIDS are more vulnerable and face greater challenges to their psychosocial well-being compared to other children of the same age. Interventions have been adopted with the aim of improving the psychosocial well-being of children affected by HIV and AIDS. ⋯ In the absence of rigorous intervention studies, the body of knowledge available consists of "lessons learned," child psychological theory and other related research in the adult population. However, such knowledge should not replace the urgent need for rigorous monitoring and evaluation of existing programs and intervention studies to ensure evidence-based practice and policy, and prevent subjecting children to interventions which show no benefit or interventions that could unintentionally lead to harm.

ReviewPneumococcal vaccines for children and adults with bronchiectasis.
Bronchiectasis is increasingly recognized as a major cause of respiratory morbidity especially in developing countries. Even in affluent countries, bronchiectasis is increasingly seen in some community subsections (e.g. Aboriginal communities) and occurs as a comorbidity and disease modifier in respiratory diseases such as chronic obstructive pulmonary disease (COPD). Respiratory exacerbations in people with bronchiectasis are associated with reduced quality of life, accelerated pulmonary decline, hospitalisation and even death. Conjugate pneumococcal vaccine is part of the routine infant immunisation schedule in many countries. Current recommendations for additional pneumococcal vaccination include children and adults with chronic suppurative disease. ⋯ Current but limited evidence support the use of 23-valent pneumococcal vaccine as routine management in adults with bronchiectasis. Circumstantial evidence also support the use of routine 23-valent pneumococcal vaccination in children with bronchiectasis. Further randomised controlled trials examining the efficacy of this intervention using various vaccine types in different age groups are needed. There is no data on the efficacy of pneumococcal vaccine on pulmonary decline. With the lack of evidence in how often the vaccine should be given, it is recommended that health providers adhere to national guidelines.

Review Meta AnalysisStimulation of the wrist acupuncture point P6 for preventing postoperative nausea and vomiting.
Postoperative nausea and vomiting (PONV) are common complications following surgery and anaesthesia. Drugs to prevent PONV are only partially effective. An alternative approach is to stimulate the P6 acupoint on the wrist. This is an update of a Cochrane review first published in 2004. ⋯ P6 acupoint stimulation prevented PONV. There was no reliable evidence for differences in risks of postoperative nausea or vomiting after P6 acupoint stimulation compared to antiemetic drugs.
