Review Meta AnalysisNegative pressure wound therapy for treating pressure ulcers.
Pressure ulcers, also known as bedsores, decubitus ulcers and pressure injuries, are localised areas of injury to the skin or the underlying tissue, or both. Negative pressure wound therapy (NPWT) is a treatment option for pressure ulcers; a clear, current overview of the evidence is required to facilitate decision-making regarding its use. ⋯ There is currently no rigorous RCT evidence available regarding the effects of NPWT compared with alternatives for the treatment of pressure ulcers. High uncertainty remains about the potential benefits or harms, or both, of using this treatment for pressure ulcer management.

Review Meta AnalysisRecombinant growth hormone therapy for cystic fibrosis in children and young adults.
Cystic fibrosis is an inherited condition causing disease most noticeably in the lungs, digestive tract and pancreas. People with cystic fibrosis often have malnutrition and growth delay. Adequate nutritional supplementation does not improve growth optimally and hence an anabolic agent, recombinant growth hormone, has been proposed as a potential intervention. ⋯ Recombinant growth hormone therapy is effective in improving the intermediate outcomes in height, weight and lean tissue mass when compared with no treatment. One measure of pulmonary function test showed moderate improvement at a single time point, but no consistent benefit was seen across all studies. No significant changes in quality of life, clinical status or side-effects were observed in this review. Long-term, well-designed randomised controlled trials of recombinant growth hormone therapy in people with cystic fibrosis are required prior to evaluation of human growth hormone treatment for routine use.

Review Meta AnalysisPoly(ADP-ribose) polymerase (PARP) inhibitors for the treatment of ovarian cancer.
Ovarian cancer is the sixth most common cancer and seventh most common cause of cancer death in women world-wide. Three-quarters of women present when the disease has spread throughout the abdomen (stage III or IV) and treatment consists of a combination of debulking surgery and platinum-based chemotherapy. Although initial responses to chemotherapy are good, most women will relapse and require further chemotherapy and will eventually develop resistance to chemotherapy.PARP (poly (ADP-ribose) polymerase) inhibitors, are a novel type of medication that works by preventing cancer cells from repairing their DNA once they have been damaged by other chemotherapy agents. It is not clear how PARP inhibitors compare to conventional chemotherapy regimens for the treatment of ovarian cancer, with respect to survival, side effects and quality of life. ⋯ PARP inhibitors appear to improve PFS in women with recurrent platinum-sensitive disease. Ongoing studies are likely to provide more information about whether the improvement in PFS leads to any change in OS in this subgroup of women with EOC. More research is needed to determine whether PARP inhibitors have any role to play in platinum-resistant disease.

Review Meta AnalysisPreoperative chemotherapy for resectable thoracic esophageal cancer.
Surgery has been the treatment of choice for patients with localized esophageal cancer. Several studies have investigated whether preoperative chemotherapy followed by surgery leads to improvement in cure rates, but individual reports have provided conflicting results. An explicit systematic update of the role of preoperative chemotherapy in the treatment of patients with resectable thoracic esophageal cancer is, therefore, warranted. ⋯ In summary, preoperative chemotherapy plus surgery offers a survival advantage compared with surgery alone for patients with resectable thoracic esophageal cancer, but the evidence is of moderate quality. Some evidence of toxicity and preoperative mortality have been associated with chemotherapy.

This is an updated version of the original Cochrane review first published in Issue 9, 2010 on "Interventions for cough in cancer". Cough is a common symptom in patients with malignancies, especially in patients with lung cancer. Cough is not well controlled in clinical practice and clinicians have few management options to treat it. ⋯ No new trials were included since the publication of the original version of this review, while 11 new studies that were identified were eventually excluded from this review. Therefore, our conclusions remain unchanged. No practice recommendations could be drawn from this review. There is an urgent need to increase the number and quality of studies evaluating the effects of interventions for the management of cough in cancer.
