ReviewCervical stitch (cerclage) for preventing pregnancy loss in women.
A cervical stitch has been used to prevent preterm deliveries in women with previous second trimester pregnancy losses, or other risk factors such as short cervix on digital or ultrasound examination. ⋯ The use of a cervical stitch should not be offered to women at low or medium risk of mid trimester loss, regardless of cervical length by ultrasound. The role of cervical cerclage for women who have short cervix on ultrasound remains uncertain as the numbers of randomised women are too few to draw firm conclusions. There is no information available as to the effect of cervical cerclage or its alternatives on the family unit and long term outcome.

Review Meta AnalysisInhaled nitric oxide for acute hypoxemic respiratory failure in children and adults.
Acute hypoxemic respiratory failure affects all age groups and may result from a number of systemic diseases. It continues to be associated with high mortality and morbidity. Initial studies examining the effect of inhaled nitric oxide in respiratory failure demonstrated transient improvement in oxygenation but did not examine mortality or other significant morbidity outcomes. ⋯ Nitric oxide did not demonstrate any statistically significant effect on mortality and transiently improved oxygenation in patients with hypoxemic respiratory failure. Lack of data prevented assessment of other clinically relevant end points. If further trials comparing inhaled nitric oxide with an inhaled placebo are to proceed, they should be stratified for primary disease, assess the impact of other combined treatment modalities for respiratory failure, and must specifically evaluate clinically relevant outcomes, before any benefit of inhaled nitric oxide for respiratory failure can be excluded.

Bulimia nervosa and like syndromes, such as binge eating disorder, are common in young Western women. A specific manual based psychotherapy, cognitive behaviour therapy (CBT) has been developed for the treatment of bulimia nervosa (CBT-BN). Other psychotherapies, some from a different theoretical framework, and some modifications of CBT are also used. ⋯ There was a small body of evidence for the efficacy of cognitive-behaviour therapy in bulimia nervosa and similar syndromes, but the quality of trials was very variable (e.g. the majority were not blinded) and sample sizes were often small in comparison to pharmacotherapy trials. More trials are needed, particularly for binge eating disorder and other EDNOS syndromes, and trials evaluating other psychotherapies and less intensive psychotherapies.

Review Meta AnalysisInhaled versus systemic corticosteroids for preventing chronic lung disease in ventilated very low birth weight preterm neonates.
Chronic lung disease (CLD) remains an important cause of mortality and morbidity in preterm infants despite the administration of antenatal corticosteroids, surfactant replacement therapy and other advances in neonatal intensive care. There is increasing evidence from cellular and biochemical research that inflammation plays an important role in the pathogenesis of CLD. Thus, interventions aimed at reducing or modulating the inflammatory process may reduce the incidence or severity of CLD. Theoretically, the use of inhaled corticosteroids may allow for beneficial effects on the pulmonary system without concomitant high systemic concentrations and less risk of adverse effects. ⋯ This review found no evidence that early inhaled steroids confer important advantages over systemic steroids in the management of ventilator dependent preterm infants. Neither inhaled steroids, nor systemic steroids, can be recommended as a part of standard practice for ventilated preterm infants. Because they might have fewer adverse effects than systemic steroids, further randomized controlled trials of inhaled steroids are needed which address risk/benefit ratio of different delivery techniques, dosing schedules and long term effects, with particular attention to neurodevelopmental outcome.

Review Meta AnalysisElective 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 intermittent positive pressure ventilation (IPPV) saves lives, lung distortion during its use is associated with lung injury and chronic lung disease (CLD). Conventional IPPV is provided at 30-80 breaths per minute while a newer form of ventilation called high frequency oscillatory ventilation (HFOV) provides 'breaths' at 10-15 cycles per second. This has been shown to result in less lung injury in experimental studies. ⋯ There is no clear evidence from this systematic review that elective HFOV, as compared with CV, offers important advantages when used as the initial ventilation strategy to treat preterm babies with acute pulmonary dysfunction. There is no evidence of a reduction in death rate. 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 is not significant overall. Adverse effects on short term neurological outcomes have been observed in some studies but these effects are not significant overall. Information about effects on long term outcome is not adequate overall. Any future trials on elective HFOV should target those infants who are at most risk of CLD (extremely preterm), compare different strategies for generating HFOV and CV, and report important long term pulmonary and neurodevelopmental outcomes. Economic analysis should also be incorporated.
