More research in the form of a high quality randomised controlled trial is needed before recommendations can be made. The results did not demonstrate a significant difference amongst low risk nulliparous women in the risks of pre-eclampsia or gestational hypertensive disorders with aspirin administration. Although we found significantly improved fetal growth parameters and prevention of preterm birth in women receiving aspirin, there were few eligible studies, with those included generally providing low quality evidence and many studies using aspirin doses ≤100 mg, commenced late in pregnancy. More research in the form of a high quality randomised controlled trial is needed before recommendations can be made.Commercial copper (Cu) is obtained by a hydro-pyrometallurgical process, where the Cu anodes obtained in the furnaces (Cu > 99.5%) are enriched up to 99.99% in "cathodes" by electrorefining at an electrolysis plant. During this process, some impurities accumulate in the electrolyte, mainly arsenic (As), which decrease the quality of the Cu cathode. For this reason, the electrolyte is sent to an electrolyte cleaning plant (ECP) for its purification. Electrolyte sludge (ES) is produced in the last stage of purification and is recirculated back to the furnace due to the high Cu content. This recirculation involves a severe problem of As accumulation in the industrial process. The objective of this work was to develop a procedure to fully dissolve the ES, removing the As and recovering its Cu content. The ES dissolution process was optimised (dissolution efficiency > 99%) in H2SO4 (1.4 M)/HNO3 (1.8 M) medium using a 120 g mL-1 solid-to-liquid ratio. As was removed from the ES solution by its precipitation as iron (III) ar
