ReviewSexual intercourse for cervical ripening and induction of labour.
The role of prostaglandins for cervical ripening and induction of labour has been examined extensively. Human semen is the biological source that is presumed to contain the highest prostaglandin concentration. The role of sexual intercourse in the initiation of labour is uncertain. The action of sexual intercourse in stimulating labour is unclear, it may in part be due to the physical stimulation of the lower uterine segment, or endogenous release of oxytocin as a result of orgasm or from the direct action of prostaglandins in semen. Furthermore nipple stimulation may be part of the process of initiation. This is one of a series of reviews of methods of cervical ripening and labour induction using standardised methodology. ⋯ The role of sexual intercourse as a method of induction of labour is uncertain. Any future trials investigating sexual intercourse as a method of induction need to be of sufficient power to detect clinically relevant differences in standard outcomes. However, it may prove difficult to standardise sexual intercourse as an intervention to allow meaningful comparisons with other methods of induction of labour.

ReviewOpioids for the palliation of breathlessness in terminal illness.
Breathlessness is a common symptom in people with advanced disease. The most effective treatments are aimed at treating the underlying cause of the breathlessness but this may not be possible and symptomatic treatment is often necessary. Strategies for the symptomatic treatment of breathlessness have never been systematically evaluated. Opioids are commonly used to treat breathlessness: the mechanisms underlying their effectiveness are not completely clear and there have been few good-sized trials in this area. ⋯ There is evidence to support the use of oral or parenteral opioids to palliate breathlessness although numbers of patients involved in the studies were small. No evidence was found to support the use of nebulised opioids. Further research with larger numbers of patients, using standardised protocols and with quality of life measures is needed.

Review Comparative StudyHospital at home versus in-patient hospital care.
Hospital at home is defined as a service that provides active treatment by health care professionals, in the patient's home, of a condition that otherwise would require acute hospital in-patient care, always for a limited period. ⋯ This review does not support the development of hospital at home services as a cheaper alternative to in-patient care. Early discharge schemes for patients recovering from elective surgery and elderly patients with a medical condition may have a place in reducing the pressure on acute hospital beds, providing the views of the carers are taken into account. For these clinical groups hospital length of stay is reduced, although this is offset by the provision of hospital at home. The evidence supporting hospital at home for patients recovering from a stroke is conflicting. There is some evidence that admission avoidance schemes may provide a less costly alternative to hospital care. Future research should focus on admission avoidance schemes, and the effect of early discharge hospital at home schemes for patients recovering from a stroke.

ReviewIntravenous immunoglobulin for preventing infection in preterm and/or low-birth-weight infants.
Nosocomial infections continue to be a significant cause of morbidity and mortality among preterm and/or low birth weight infants. Maternal transport of immunoglobulins to the fetus mainly occurs after 32 weeks gestation and endogenous synthesis does not begin until several months after birth. Administration of intravenous immunoglobulin provides IgG that can bind to cell surface receptors, provide opsonic activity, activate complement, promote antibody dependent cytotoxicity, and improve neutrophilic chemoluminescence. Intravenous immunoglobulin thus has the potential of preventing or altering the course of nosocomial infections. ⋯ IVIG administration results in a 3% reduction in sepsis and a 4 % reduction in any serious infection, one or more episodes, but is not associated with reductions in other important outcomes: sepsis, NEC, IVH, or length of hospital stay. Most importantly IVIG administration does not have any effect on mortality from any cause or from infections. Prophylactic use of IVIG is not associated with any short term serious side effects. From a clinical perspective a 3-4% reduction in nosocomial infections without a reduction in mortality or other important clinical outcomes is of marginal importance. The decision to use prophylactic IVIG will depend on the costs and the values assigned to the clinical outcomes. There is no justification for further RCTs testing the efficacy of previously studied IVIG preparations to reduce nosocomial infections in preterm and/or LBW infants. The results of these meta-analyses should encourage basic scientists and clinicians to pursue other avenues to prevent nosocomial infections.

ReviewSynchronized mechanical ventilation for respiratory support in newborn infants.
During synchronized mechanical ventilation, positive airway pressure and spontaneous inspiration coincide. Thus, if synchronous ventilation is provoked, it is likely that adequate gas exchange should be achieved at lower peak airway pressures, reducing barotrauma and hence airleak and chronic lung disease. Synchronous ventilation can be achieved by manipulation of rate and inspiratory time during conventional ventilation and employment of patient assisted ventilation. ⋯ Compared to conventional ventilation, benefit is demonstrated for both HFPPV and triggered ventilation with regard to a reduction in airleak and a shorter duration of ventilation respectively. In none of the trials was complex respiratory monitoring undertaken and thus it is not possible to conclude that the mechanism of producing those benefits is by provocation of synchronized ventilation. Further trials are needed to determine whether synchronized ventilation is associated with other benefits but optimization of trigger and ventilator design with respect to respiratory diagnosis is encouraged before embarking on further trials.
