Review Meta AnalysisProphylactic oral/topical non-absorbed antifungal agents to prevent invasive fungal infection in very low birth weight infants.
Invasive fungal infection is an important cause of mortality and morbidity in very preterm (< 32 weeks gestation) or very low birth weight (VLBW) infants. Clinical uncertainly exists about the effect of prophylactic oral/topical non-absorbed antifungals to reduce mucocutaneous colonisation and so limit the risk of invasive fungal infection in this population. ⋯ The finding of a reduction in risk of invasive fungal infection in infants treated with oral/topical non-absorbed antifungal prophylaxis should be interpreted cautiously because of methodological weaknesses in the included trials. Further large randomised controlled trials in current neonatal practice settings are needed to resolve this uncertainty. These trials might compare oral/topical non-absorbed antifungal agents with placebo, with each other, or with systemic antifungal agents and should include an assessment of effect on long-term neurodevelopmental outcomes.

Review Meta Analysis Comparative StudyRobot assistant for laparoscopic cholecystectomy.
The role of a robotic assistant in laparoscopic cholecystectomy is controversial. While some trials have shown distinct advantages of robotic assistant over a human assistant, others have not, and it is unclear which robotic assistant is best. ⋯ Although robot-assisted laparoscopic cholecystectomy appears safe, there seems to be no significant advantages over human-assisted laparoscopic cholecystectomy. We were unable to identify trials comparing one type of robot assistant versus another. Further randomised trials with low bias-risk and random errors are needed.

Review Meta Analysis Comparative StudyElective high frequency oscillatory ventilation versus conventional ventilation for acute pulmonary dysfunction in preterm infants.
Respiratory failure due to lung immaturity is a major cause of mortality in preterm infants. Although the use of intermittent positive pressure ventilation (IPPV) in neonates with respiratory failure saves lives, its use is associated with lung injury and chronic lung disease (CLD). A newer form of ventilation called high frequency oscillatory ventilation (HFOV) has been shown to result in less lung injury in experimental studies. ⋯ There is no clear evidence that elective HFOV offers important advantages over CV when used as the initial ventilation strategy to treat preterm infants with acute pulmonary dysfunction. There may be a small reduction in the rate of CLD with HFOV use, but the evidence is weakened by the inconsistency of this effect across trials and the overall borderline significance. Future trials on elective HFOV should target those infants who are at most risk of CLD (extremely preterm infants), compare different strategies for generating HFOV and CV, and report important long-term neurodevelopmental outcomes.

ReviewHypothermia for neuroprotection in adults after cardiopulmonary resuscitation.
Good neurologic outcome after cardiac arrest is hard to achieve. Interventions during the resuscitation phase and treatment within the first hours after the event are critical. Experimental evidence suggests that therapeutic hypothermia is beneficial, and a number of clinical studies on this subject have been published. ⋯ Conventional cooling methods to induce mild therapeutic hypothermia seem to improve survival and neurologic outcome after cardiac arrest. Our review supports the current best medical practice as recommended by the International Resuscitation Guidelines.

Review Meta AnalysisOverground physical therapy gait training for chronic stroke patients with mobility deficits.
Overground gait training forms a major part of physical therapy services for chronic stroke patients in almost every setting. Overground gait training refers to physical therapists' observation and cueing of the patient's walking pattern along with related exercises, but does not include high-technology aids such as functional electrical stimulation or body weight support. ⋯ We found insufficient evidence to determine if overground physical therapy gait training benefits gait function in patients with chronic stroke, though limited evidence suggests small benefits for uni-dimensional variables such as gait speed or 6MWT. These findings must be replicated by large, high quality studies using varied outcome measures.
