Review Meta AnalysisAntibiotics versus placebo for prevention of postoperative infection after appendicectomy.
Appendicitis is the most common cause of acute abdominal pain requiring surgical intervention. The cause of appendicitis is unclear and the mechanism of pathogenesis continues to be debated. Despite improved asepsis and surgical techniques, postoperative complications, such as wound infection and intraabdominal abscess, still account for a significant morbidity. Several studies implicate that postoperative infections are reduced by administration of antimicrobial regimes. ⋯ Antibiotic prophylaxis is effective in the prevention of postoperative complications in appendectomised patients, whether the administration is given pre-, peri- or post-operatively, and could be considered for routine in emergency appendectomies.

Review Meta AnalysisAntibiotics for the common cold and acute purulent rhinitis.
It has long been believed that antibiotics have no role in treating common colds yet they are often prescribed in the belief that they may prevent secondary bacterial infections. Given the increasing concerns about antibiotic resistance it is important to examine the evidence for the benefit of antibiotics for the common cold. ⋯ There is insufficient evidence of benefit to warrant the use of antibiotics for upper respiratory tract infections in children or adults. Antibiotics cause significant adverse effects in adults. The evidence on acute purulent rhinitis and acute clear rhinitis suggests a benefit for antibiotics for these conditions but their routine use is not recommended.

HIV-infected people and AIDS patients often seek complementary therapies including herbal medicines due to reasons such as unsatisfactory effects, high cost, non-availability, or adverse effects of conventional medicines. ⋯ There is insufficient evidence to support the use of herbal medicines in HIV-infected individuals and AIDS patients. Potential beneficial effects need to be confirmed in large, rigorous trials.

Review Meta Analysis Comparative StudyHospital at home versus in-patient hospital care.
Hospital at home is defined as a service that provides active treatment by health care professionals, in the patient's home, of a condition that otherwise would require acute hospital in-patient care, always for a limited period. ⋯ Despite increasing interest in the potential of hospital at home services as a cheaper alternative to in-patient care, this review provides insufficient objective evidence of economic benefit. Early discharge schemes for patients recovering from elective surgery and elderly patients with a medical condition may have a place in reducing the pressure on acute hospital beds, providing the views of the carers are taken into account. For these clinical groups hospital length of stay is reduced, although this is offset by the provision of hospital at home. Future primary research should focus on rigorous evaluations of admission avoidance schemes and standards for original research should aim at assisting future meta-analyses of individual patient data from these and future trials.

Review Meta AnalysisInterventions for preventing obesity in children.
Obesity prevention is an international public health priority. The prevalence of obesity and overweight is increasing in child populations throughout the world, impacting on short and long-term health. Obesity prevention strategies for children can change behaviour but efficacy in terms of preventing obesity remains poorly understood. ⋯ The majority of studies were short-term. Studies that focused on combining dietary and physical activity approaches did not significantly improve BMI, but some studies that focused on dietary or physical activity approaches showed a small but positive impact on BMI status. Nearly all studies included resulted in some improvement in diet or physical activity. Appropriateness of development, design, duration and intensity of interventions to prevent obesity in childhood needs to be reconsidered alongside comprehensive reporting of the intervention scope and process.
