    Notes: Abstract Field measurement programs in Brazil during the dry seasons in August and September 1979 and 1980 have demonstrated the large importance of the continental tropics in global air chemistry. Many important trace gases are produced in large amounts over the continents. During the dry season, much biomass burning takes place, especially in the cerrado regions, leading to a substantial emission of air pollutants, such as CO, NO x , N2O, CH4 and other hydrocarbons. Ozone concentrations are enhanced due to photochemical reactions. The large biogenic organic emissions from tropical forests play an important role in the photochemistry of the atmosphere and explain why CO is present in such high concentrations in the boundary layer of the tropical forest. Carbon monoxide production may represent more than 3% of the net primary productivity of the tropical forests. Ozone concentrations in the boundary layer of the tropical forests indicate strong removal processes. Due to atmospheric supply of NO x by lightning, there is probably a large production of O3 in the free troposphere over the Amazon tropical forests. This is transported to the marine-free troposphere and to the forest boundary layer.

    Description: Introduction Maternal mortality is a potentially preventable public health issue. Maternal morbidity is increasingly of interest to aid the reduction of maternal mortality. Obstetric patients admitted to the intensive care unit (ICU) are an important part of the global burden of maternal morbidity. Social determinants influence health outcomes of pregnant women. Additionally, intimate partner violence has a great negative impact on women's health and pregnancy outcome. However, little is known about the contextual and social aspects of obstetric patients treated in the ICU. This study aimed to conduct a systematic review of the social determinants and exposure to intimate partner violence of obstetric patients admitted to an ICU. Methods and analysis A systematic search will be conducted in MEDLINE, CINAHL, ProQuest, LILACS and SciELO from 2000 to 2016. Studies published in English and Spanish will be identified in relation to data reporting on social determinants of health and/or exposure to intimate partner violence of obstetric women, treated in the ICU during pregnancy, childbirth or within 42 days of the end of pregnancy. Two reviewers will independently screen for study eligibility and data extraction. Risk of bias and assessment of the quality of the included studies will be performed by using the Critical Appraisal Skills Programme (CASP) checklist. Data will be analysed and summarised using a narrative description of the available evidence across studies. This systematic review protocol will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines. Ethics and dissemination Since this systematic review will be based on published studies, ethical approval is not required. Findings will be presented at La Trobe University, in Conferences and Congresses, and published in a peer-reviewed journal. Trial registration number CRD42016037492.
