Nephrotic syndrome is the collective name given to a group of symptoms that include proteinuria, lipiduria, hypoalbuminaemia, oedema, hypercholesterolaemia, elevated triglycerides, and hyperlipidaemia. Hyperlipidaemia is thought to aggravate glomerulosclerosis (hardening of blood vessels in the kidneys) and enhance progression of glomerular disease. Studies have established that reduction in total cholesterol and low density lipoprotein (LDL) cholesterol is associated with reduction in risk of cardiovascular diseases. In 2011, the European Society of Cardiology and European Atherosclerosis Society guidelines for the management of dyslipidaemia recommended use of statins as first-line agents in the management of nephrotic dyslipidaemia. However, the effectiveness and safety of statins for people with nephrotic syndrome remains uncertain. Furthermore, the efficacy of second-line lipid-lowering drugs, such as ezetimibe and nicotinic acid, has not been proven in patients with nephrotic syndrome who are unable to tolerate statin therapy. ⋯ None of the included studies reported patient-centred outcomes including all-cause mortality, cardiovascular mortality, or non-fatal myocardial infarction; only single studies reported cholesterol (HDL, LDL and total cholesterol), triglycerides, serum creatinine, blood urea nitrogen, liver enzymes, and protein (serum, urine). High quality RCTs need to be conducted to assess the safety and efficacy of lipid-lowering drugs for people with nephrotic syndrome.

Review Meta AnalysisPhytoestrogens for menopausal vasomotor symptoms.
Vasomotor symptoms, such as hot flushes and night sweats, are very common during the menopausal transition. Hormone therapy has traditionally been used as a highly effective treatment, but concerns about increased risk of some chronic diseases have markedly increased the interest of women in alternative treatments. Some of the most popular of these treatments are foods or supplements enriched with phytoestrogens-plant-derived chemicals that have estrogenic action. ⋯ No conclusive evidence shows that phytoestrogen supplements effectively reduce the frequency or severity of hot flushes and night sweats in perimenopausal or postmenopausal women, although benefits derived from concentrates of genistein should be further investigated.

Review Meta AnalysisInterventions for the symptoms and signs resulting from jellyfish stings.
Jellyfish envenomations are common amongst temperate coastal regions and vary in severity depending on the species. Stings result in a variety of symptoms and signs, including pain, dermatological reactions and, in some species, Irukandji syndrome (including abdominal/back/chest pain, tachycardia, hypertension, sweating, piloerection, agitation and sometimes cardiac complications). Many treatments have been suggested for the symptoms and signs of jellyfish stings. However, it is unclear which interventions are most effective. ⋯ This review located a small number of trials that assessed a variety of different interventions applied in different ways and in different settings. Although heat appears to be an effective treatment for Physalia (Bluebottle) stings, this evidence is based on a single trial of low-quality evidence. It is still unclear what type of application, temperature, duration of treatment and type of water (salt or fresh) constitute the most effective treatment. In addition, these results may not apply to other species of jellyfish with different envenomation characteristics. Future research should further assess the most effective interventions using standardised research methodology.

Review Meta AnalysisNoninvasive positive-pressure ventilation as a weaning strategy for intubated adults with respiratory failure.
Noninvasive positive-pressure ventilation (NPPV) provides ventilatory support without the need for an invasive airway. Interest has emerged in using NPPV to facilitate earlier removal of an endotracheal tube and to decrease complications associated with prolonged intubation. ⋯ Summary estimates from 16 trials of moderate to good quality that included predominantly participants with COPD suggest that a weaning strategy that includes NPPV may reduce rates of mortality and ventilator-associated pneumonia without increasing the risk of weaning failure or reintubation.
