It has been suggested that oestrogens may improve fetal growth due to an increase in nutritional supply to the fetus from greater uterine blood flow. ⋯ There is not enough evidence to evaluate the clinical use of hormone administration for suspected impaired fetal growth.

ReviewInhaled beta-agonists for asthma in mechanically ventilated patients.
A small number of patients with acute severe asthma require intubation and positive pressure ventilation. The beneficial effects of inhaled bronchodilators on acute asthma in spontaneously breathing subjects are well established, but there remain important questions regarding inhaled beta2-agonists, for patients who are intubated and receiving ventilation. ⋯ There are no data from randomised controlled trials to provide evidence for or against current practices regarding the use of inhaled beta2-agonists in asthmatic subjects who are intubated and ventilated.

To estimate the short-term effects of cyclophosphamide for the treatment of rheumatoid arthritis. ⋯ Cyclophosphamide appears to have a clinically and statistically significant benefit on the disease activity of patients with RA, similar to some disease modifying antirheumatic drugs (DMARDs) such as antimalarials or sulfasalazine, but lower than methotrexate. Toxicity however is severe, limiting its use given the low benefit-risk ratio compared to other antirheumatic agents.

ReviewNedocromil sodium for preventing exercise-induced bronchoconstriction.
Exercise-induced asthma causes cough, dyspnea, wheeze and chest tightness. Management of focuses on prevention through pharmaco-therapy and alternate strategies. Single use, pre-exercise beta2-agonists and non-steroidal anti-inflammatory agents such as the cromones are the most common treatments. ⋯ Nedocromil sodium used before exercise appears to reduce the severity and duration of exercise-induced bronchoconstriction. This effect appears to be more pronounced in people with severe exercise-induced bronchoconstriction.

To assess the effects of advising pregnant women to increase their energy and protein intakes on those intakes, on gestational weight gain, and on the outcome of pregnancy. ⋯ Nutritional advice appears effective in increasing pregnant women's energy and protein intakes, but the implications for fetal, infant, or maternal health cannot be judged from the available trials. Given the rather modest health benefits demonstrated with actual protein/energy supplementation (see the Cochrane review of 'Balanced protein/energy supplementation in pregnancy'), however, the provision of such advice is unlikely to be of major importance.
