Review Meta AnalysisTopical ointment for preventing infection in preterm infants.
Nosocomial sepsis is a frequent and serious complication of premature infants. The increased susceptibility of ELBW infants to infection has been attributed to less effective immune function compared to mature newborns and the invasive nature of necessary supportive care. Breakdown of the barrier function of the skin may be an additional risk factor for nosocomial sepsis. ⋯ Prophylactic application of topical ointment increases the risk of coagulase negative staphylococcal infection and any nosocomial infection. A trend toward increased risk of any bacterial infection was noted in infants prophylactically treated. Topical ointment should not be used routinely in preterm infants.

Review Meta AnalysisIntravenous 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 chemo luminescence. 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 significant 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.

ReviewAromatherapy and massage for symptom relief in patients with cancer.
Aromatherapy massage is a commonly used complementary therapy, and is employed in cancer and palliative care largely to improve quality of life and reduce psychological distress. ⋯ Massage and aromatherapy massage confer short term benefits on psychological wellbeing, with the effect on anxiety supported by limited evidence. Effects on physical symptoms may also occur. Evidence is mixed as to whether aromatherapy enhances the effects of massage. Replication, longer follow up, and larger trials are need to accrue the necessary evidence.

Review Meta AnalysisProphylactic platelet transfusion for haemorrhage after chemotherapy and stem cell transplantation.
Platelet transfusions are used in modern clinical practice to prevent and treat bleeding in thrombocytopenic patients with bone marrow failure. Although considerable advances have been made in platelet transfusion therapy in the last 30 years, some areas continue to provoke debate, especially the use of prophylactic platelet transfusions for the prevention of thrombocytopenic bleeding. ⋯ There are no reasons to change current practice but uncertainty about the practice of prophylactic transfusion therapy should be recognised, particularly in the light of concerns about the scenario that blood products, including platelets, could become an increasingly scarce resource in the future and for which adequate alternatives do not exist. Consideration should be given to developing adequately powered trials comparing strategies of prophylaxis versus therapeutic platelet transfusion.

Review Meta AnalysisAntiplatelet agents and anticoagulants for hypertension.
Although elevated systemic blood pressure results in high intravascular pressure, the main complications, coronary heart disease (CHD), ischaemic strokes and peripheral vascular disease (PVD), are related to thrombosis rather than haemorrhage. Some complications related to elevated blood pressure, heart failure or atrial fibrillation, are themselves associated with stroke and thromboembolism. It therefore seemed plausible that use of antithrombotic therapy may be particularly useful in preventing thrombosis-related complications of elevated blood pressure. ⋯ For primary prevention in patients with elevated blood pressure, anti-platelet therapy with ASA cannot be recommended since the magnitude of benefit, a reduction in myocardial infarction, is negated by a harm of similar magnitude, an increase in major haemorrhage. For secondary prevention in patients with elevated blood pressure (ATC meta-analysis: APTC 1994) antiplatelet therapy is recommended because the magnitude of the absolute benefit is many times greater. Warfarin therapy alone or in combination with aspirin in patients with elevated blood pressure cannot be recommended because of lack of demonstrated benefit. Glycoprotein IIb/IIIa inhibitors as well as ticlopidine and clopidogrel have not been sufficiently evaluated in patients with elevated blood pressure. Further trials of antithrombotic therapy with complete documentation of all benefits and harms are required in patients with elevated blood pressure.
