Review Meta AnalysisInterventions for dysphagia in oesophageal cancer.
Most patients with oesophageal and gastro-oesophageal carcinoma are diagnosed at an advanced stage and require palliative intervention. Although there are many kinds of interventions, the optimal one for the palliation of dysphagia remains unclear. This review updates the previous version published in 2009. ⋯ Self-expanding metal stent insertion is safe, effective and quicker in palliating dysphagia compared to other modalities. However, high-dose intraluminal brachytherapy is a suitable alternative and might provide additional survival benefit with a better quality of life. Some anti-reflux stents and newly-designed stents lead to longer survival and fewer complications compared to conventional stents. Combinations of brachytherapy with self-expanding metal stent insertion or radiotherapy are preferable due to the reduced requirement for re-interventions. Rigid plastic tube insertion, dilatation alone or in combination with other modalities, and chemotherapy alone are not recommended for palliation of dysphagia due to a high incidence of delayed complications and recurrent dysphagia.

Review Meta AnalysisQuantitative versus qualitative cultures of respiratory secretions for clinical outcomes in patients with ventilator-associated pneumonia.
Ventilator-associated pneumonia (VAP) is a common infectious disease in intensive care units (ICUs). The best diagnostic approach to resolve this condition remains uncertain. ⋯ There is no evidence that the use of quantitative cultures of respiratory secretions results in reduced mortality, reduced time in ICU and on mechanical ventilation, or higher rates of antibiotic change when compared to qualitative cultures in patients with VAP. We observed similar results when invasive strategies were compared with non-invasive strategies.

Review Meta AnalysisColony-stimulating factors for chemotherapy-induced febrile neutropenia.
Febrile neutropenia is a frequent adverse event experienced by people with cancer who are undergoing chemotherapy, and is a potentially life-threatening situation. The current treatment is supportive care plus antibiotics. Colony-stimulating factors (CSFs), such as granulocyte-CSF (G-CSF) and granulocyte-macrophage CSF (GM-CSF), are cytokines that stimulate and accelerate the production of one or more cell lines in the bone marrow. Clinical trials have addressed the question of whether the addition of a CSF to antibiotics could improve outcomes in individuals diagnosed with febrile neutropenia. However, the results of these trials are conflicting. ⋯ The use of a CSF plus antibiotics in individuals with chemotherapy-induced febrile neutropenia had no effect on overall mortality, but reduced the amount of time participants spent in hospital and improved their ability to achieve neutrophil recovery. It was not clear whether CSF plus antibiotics had an effect on infection-related mortality. Participants receiving CSFs had shorter duration of neutropenia, faster recovery from fever and shorter duration of antibiotics use.

Each year about two million pregnant women are infected with preventable syphilis infection, mostly in developing countries. Despite the expansion of antenatal syphilis screening programmes over the past few decades, syphilis continues to be a major public health concern in developing countries. Point-of-care syphilis testing may be a useful strategy to substantially prevent syphilis-associated perinatal mortality and other negative consequences in resource-poor settings. However, the evidence on effectiveness has been generated mostly from observational study designs or has been reported as a mixed-intervention effect. ⋯ This review included evidence from two cluster-randomised trials at high or unclear risk of bias for most of the 'Risk of bias' domains. Data were not combined in meta-analysis because the trials used non-comparable measures of effectiveness.Point-of-care syphilis testing showed some promising results for syphilis detection and treatment rates and for use in different settings. In Mongolia point-of-care testing was found to be effective in increasing the proportion of pregnant women tested for syphilis and treatment provided, reducing congenital syphilis, and improving access to treatment for both women and their partners. In contrast, in rural South Africa, among women with positive test results, there was no clear evidence of an effect of point-of-care syphilis testing in increasing adequate syphilis treatment rates, and reducing perinatal mortality, but point-of-care testing was found to reduce delay in seeking treatment.More trials are therefore warranted to determine the effectiveness of available testing strategies for improving syphilis-associated adverse outcomes in pregnant women and neonates, especially in high-risk regions.

Review Meta AnalysisAntibiotics for prelabour rupture of membranes at or near term.
Prelabour rupture of the membranes (PROM) at or near term (defined in this review as 36 weeks' gestation or beyond) increases the risk of infection for the woman and her baby. The routine use of antibiotics for women at the time of term PROM may reduce this risk. However, due to increasing problems with bacterial resistance and the risk of maternal anaphylaxis with antibiotic use, it is important to assess the evidence addressing risks and benefits in order to ensure judicious use of antibiotics. This review was undertaken to assess the balance of risks and benefits to the mother and infant of antibiotic prophylaxis for PROM at or near term. ⋯ This updated review demonstrates no convincing evidence of benefit for mothers or neonates from the routine use of antibiotics for PROM at or near term. We are unable to adequately assess the risk of short- and long-term harms from the use of antibiotics due to the unavailability of data. Given the unmeasured potential adverse effects of antibiotic use, the potential for the development of resistant organisms, and the low risk of maternal infection in the control group, the routine use of antibiotics for PROM at or near term in the absence of confirmed maternal infection should be avoided.
