Review Meta AnalysisPrimaquine for preventing relapses in people with Plasmodium vivax malaria.
Plasmodium vivax infections contribute to a significant proportion of the malaria infections in many countries. Primaquine is the most widely used drug for treating the dormant liver stage. Different primaquine dosing regimens are in use. ⋯ Primaquine (15 mg/kg/day for 14 days) plus chloroquine is more effective than chloroquine alone or primaquine (15 mg/kg for 5 days) plus chloroquine in preventing relapses of vivax malaria. Primaquine (five days) plus chloroquine appears no better than chloroquine. Countries should follow the WHO's recommendation for 14-day primaquine plus chloroquine regimen. Alternative regimens need to be evaluated in randomized controlled trials, which should also consider variations in regional P. vivax strains and the possibility of primaquine resistance, reinfection, and adherence in those who relapse.

Review Meta AnalysisDietary advice for illness-related malnutrition in adults.
Illness-related malnutrition has been reported in 10% to 55% of ill people in hospital and the community in areas of food sufficiency. Dietary advice encouraging the use of energy- and nutrient-rich foods rather than oral nutritional supplements has been suggested for managing illness-related malnutrition. ⋯ This review highlights the lack of evidence for the provision of dietary advice in managing illness-related malnutrition. Dietary advice plus nutritional supplements may be more effective than dietary advice alone or no advice in enhancing short-term weight gain, but whether this is sustainable, or whether survival and morbidity are improved remains uncertain. A large adequately-powered randomised controlled trial is needed comparing the efficacy of different therapies to increase dietary intake in people with illness-related malnutrition and examining the impact of this on clinical function and survival.

Review Meta AnalysisAntibiotics for treating bacterial vaginosis in pregnancy.
Bacterial vaginosis is an imbalance of the normal vaginal flora with an overgrowth of anaerobic bacteria and a lack of the normal lactobacillary flora. Bacterial vaginosis during pregnancy has been associated with poor perinatal outcome and, in particular, preterm birth (PTB). Identification and treatment may reduce the risk of PTB and its consequences. ⋯ Antibiotic treatment can eradicate bacterial vaginosis in pregnancy. This review provides little evidence that screening and treating all pregnant women with asymptomatic bacterial vaginosis will prevent PTB and its consequences. However, there is some suggestion that treatment before 20 weeks' gestation may reduce the risk of PTB. This needs to be further verified by future trials.

Treatment options for tubal ectopic pregnancy are; (1) surgery, e.g. salpingectomy or salpingo(s)tomy, either performed laparoscopically or by open surgery; (2) medical treatment, with a variety of drugs, that can be administered systemically and/or locally by various routes and (3) expectant management. ⋯ In the surgical treatment of tubal ectopic pregnancy laparoscopic surgery is a cost effective treatment. An alternative nonsurgical treatment option in selected patients is medical treatment with systemic methotrexate. Expectant management can not be adequately evaluated yet.

Review Meta AnalysisEffects of glucocorticoids on radiological progression in rheumatoid arthritis.
Glucocorticoid use in rheumatoid arthritis (RA) is widespread. Two Cochrane Reviews have been published examining the short term clinical benefit of low dose glucocorticoids compared to non-steroidal anti-inflammatory drugs and demonstrate good short term and medium term clinical benefits. The possibility that glucocorticoids may have a fundamental 'disease modifying' effect in RA, which would be seen by a reduction in the rate of radiological progression, has been raised by several authors. ⋯ Even in the most conservative estimate, the evidence that glucocorticoids given in addition to standard therapy can substantially reduce the rate of erosion progression in rheumatoid arthritis is convincing. There remains concern about potential long-term adverse reactions to glucocorticoid therapy, such as increased cardiovascular risk, and this issue requires further research.
