Review Meta Analysis Comparative StudyOff-pump versus on-pump coronary artery bypass grafting for ischaemic heart disease.
Coronary artery bypass grafting (CABG) is performed both without and with cardiopulmonary bypass, referred to as off-pump and on-pump CABG respectively. However, the preferable technique is unclear. ⋯ Our systematic review did not demonstrate any significant benefit of off-pump compared with on-pump CABG regarding mortality, stroke, or myocardial infarction. In contrast, we observed better long-term survival in the group of patients undergoing on-pump CABG with the use of cardiopulmonary bypass and cardioplegic arrest. Based on the current evidence, on-pump CABG should continue to be the standard surgical treatment. However, off-pump CABG may be acceptable when there are contraindications for cannulation of the aorta and cardiopulmonary bypass. Further randomised clinical trials should address the optimal treatment in such patients.

Neck disorders are common, disabling, and costly. The effectiveness of patient education strategies is unclear. ⋯ With the exception of one trial, this review has not shown effectiveness for educational interventions, including advice to activate, advice on stress-coping skills, workplace ergonomics and self-care strategies. Future research should be founded on sound adult learning theory and learning skill acquisition.

Review Meta AnalysisInositol for respiratory distress syndrome in preterm infants.
Inositol is an essential nutrient required by human cells in culture for growth and survival. Inositol promotes maturation of several components of surfactant and may play a critical role in fetal and early neonatal life. ⋯ Inositol supplementation results in statistically significant and clinically important reductions in important short-term adverse neonatal outcomes. A multicenter randomized controlled trial of appropriate size is justified to confirm these findings.

Review Meta AnalysisPostoperative adjuvant chemotherapy in rectal cancer operated for cure.
Colorectal cancer is one of the most common types of cancer in the Western world. Apart from surgery - which remains the mainstay of treatment for resectable primary tumours - postoperative (i.e., adjuvant) chemotherapy with 5-fluorouracil (5-FU) based regimens is now the standard treatment in Dukes' C (TNM stage III) colon tumours i.e. tumours with metastases in the regional lymph nodes but no distant metastases. In contrast, the evidence for recommendations of adjuvant therapy in rectal cancer is sparse. In Europe it is generally acknowledged that locally advanced rectal tumours receive preoperative (i.e., neoadjuvant) downstaging by radiotherapy (or chemoradiotion), whereas in the US postoperative chemoradiotion is considered the treatment of choice in all Dukes' C rectal cancers. Overall, no universal consensus exists on the adjuvant treatment of surgically resectable rectal carcinoma; moreover, no formal systematic review and meta-analysis has been so far performed on this subject. ⋯ The results of this meta-analysis support the use of 5-FU based postoperative adjuvant chemotherapy for patients undergoing apparently radical surgery for non-metastatic rectal carcinoma. Available data do not allow us to define whether the efficacy of this treatment is highest in one specific TNM stage. The implementation of modern anti-cancer agents in the adjuvant setting is warranted to improve the results shown by this meta-analysis. Randomized trials of adjuvant chemotherapy for patients receiving preoperative neoadjuvant therapy are also needed in order to define the role of postoperative chemotherapy in the multimodal treatment of resectable rectal cancer.

Review Meta AnalysisMedications for increasing milk supply in mothers expressing breastmilk for their preterm hospitalised infants.
Breastmilk remains the optimal form of enteral nutrition for term and preterm infants until up to six months postnatal age. Mothers of preterm infants who have not established suck feeds must express their breastmilk and often have difficulty in maintaining sufficient volume for their infants' needs (Donath 2008). In preterm infants, donor breastmilk reduced the occurrence of necrotising enterocolitis, when compared with formula feeds (McGuire 2003). Also, case-control studies have suggested that breastmilk is associated with an improvement in feeding tolerance, a reduction in significant gastrointestinal infective events (Beeby 1992) and a reduction in late-onset sepsis (Schanler 1999) when compared with formula feeds in preterm hospitalised infants. ⋯ Two studies with a total of 59 mothers suggest modest improvements in short-term EBM volumes when a medication is used after insufficient EBM occurs in mothers following preterm delivery. In both studies, the medication was commenced ≧14 days post delivery and following insufficient EBM supply with other lactation supports.Currently, no studies support prophylactic use of a galactagogue medication at any gestation. Use of any galactagogue medication has only been examined at more than 14 days post delivery and after full lactation support has been given. Further trials should examine larger groups of preterm mothers and consider breastfeeding outcomes over a longer period.
