Biomechanical factors, such as reduced muscle strength and joint mal-alignment, have an important role in the initiation and progression of osteoarthritis (OA) of the hip or knee. Currently, there is no known cure for OA, however, disease-related factors, such as impaired muscle function and reduced fitness, are potentially amenable to therapeutic exercise. ⋯ Land-based therapeutic exercise was shown to reduce pain and improve physical function for people with OA of the knee. There were insufficient data to provide useful guidelines on optimal exercise type or dosage. Supervised exercise classes appeared to be as beneficial as treatments provided on a one-to-one basis.

Osteoarthritis (OA) is the most common form of arthritis. Published guidelines and expert opinion are divided over the relative role of acetaminophen (also called paracetamol or Tylenol) and non-steroidal anti-inflammatory drugs (NSAIDs) as first-line pharmacologic therapy. The comparative safety of acetaminophen and NSAIDs is important to consider as NSAIDs have the potential for serious gastrointestinal, renal, and cardiovascular toxicities, and acetaminophen in high dosages (greater than or equal to 2 grams per day), may also have the potential for serious upper gastrointestinal toxicity. ⋯ The evidence to date suggests that NSAIDs are superior to acetaminophen for improving knee and hip pain in people with OA but have not been shown to be superior in improving function. The size of the treatment effect was modest, and the mean trial duration was only six weeks, therefore, additional considerations need to be factored in when making the decision between using acetaminophen or NSAIDs. In OA subjects with moderate-to-severe levels of pain, NSAIDs appear to be more effective than acetaminophen.

ReviewVentilation with lower tidal volumes versus traditional tidal volumes in adults for acute lung injury and acute respiratory distress syndrome.
Patients with acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) require mechanical ventilatory support. ALI/ARDS is further complicated by ventilator-induced lung injury. Lung-protective ventilation strategies may lead to improved survival. ⋯ Clinical heterogeneity, such as different lengths of follow up and higher plateau pressure in control arms in two trials make the interpretation of the combined results difficult. Mortality is significantly reduced at day 28 and the effects on long term mortality are uncertain, although the possibility of a clinically relevant benefit cannot be excluded. There is no evidence that low Vt ventilation is beneficial in patients where hypercapnia is potentially harmful.

ReviewAntimicrobial drugs for treating methicillin-resistant Staphylococcus aureus colonization.
Eradication strategies for methicillin-resistant Staphylococcus aureus (MRSA) are variable. We sought to summarize the evidence for use of antimicrobial agents to eradicate MRSA. ⋯ There is insufficient evidence to support use of topical or systemic antimicrobial therapy for eradicating nasal or extra-nasal MRSA. There is no demonstrated superiority of either topical or systemic therapy, or of combinations of these agents. Potentially serious adverse events and development of antimicrobial resistance can result from therapy.

ReviewTreatments for gestational diabetes and impaired glucose tolerance in pregnancy.
Gestational diabetes and impaired glucose tolerance (IGT) in pregnancy affects between 3 and 6% of all pregnancies and both have been associated with pregnancy complications. A lack of conclusive evidence has led clinicians to equate the risk of adverse perinatal outcome with pre-existing diabetes. Consequently, women are often intensively managed with increased obstetric monitoring, dietary regulation, and in some cases insulin therapy. However, there has been no sound evidence base to support intensive treatment. The key issue for clinicians and consumers is whether treatment of gestational diabetes and IGT will improve perinatal outcome. ⋯ There are insufficient data for any reliable conclusions about the effects of treatments for impaired glucose tolerance on perinatal outcome.
