World Prematurity Day 17th November 2017 We would like to highlight WHO World Prematurity Day. Premature birth is a very serious health problem. Worldwide, 15 million babies are born preterm and more than a million die as a result. Babies who survive often have lifelong health problems such as cerebral palsy, vision and hearing loss, and intellectual disabilities.
Abstract We investigated an outbreak of exanthematous illness in Maceió by using molecular surveillance; 76% of samples tested positive for chikungunya virus. Genetic analysis of 23 newly generated genomes identified the East/Central/South African genotype, suggesting that this lineage has persisted since mid-2014 in Brazil and may spread in the Americas and beyond.
Abstract Background Chikungunya fever is a globally spreading mosquito-borne disease that shows an unexpected neu- rovirulence. Even though the neurological complications have been a major cause of intensive care unit admission and death, to date, there is no systematic analysis of their spectrum available. Objective To review evidence of neurological manifesta- tions in Chikungunya fever and map their epidemiology, clinical spectrum, pathomechanisms, diagnostics, therapies and outcomes. Methods Case report and systematic review of the litera- ture followed established guidelines. All cases found were assessed using a 5-step clinical diagnostic algorithm assigning categories A–C, category A representing the highest level of quality. Only A and B cases were con- sidered for further analysis. After general analysis, cases were clustered according to geospatial criteria for subgroup analysis. Results Thirty-six of 1196 studies were included, yielding 130 cases. Nine were ranked as category A (diagnosis of Neuro-Chikungunya probable), 55 as B (plausible), and 51 as C (disputable). In 15 cases, alternative diagnoses were more likely. Patient age distribution was bimodal with a mean of 49 years and a second peak in infants. Fifty per- cent of the cases occurred in patients <45 years with no reported comorbidity. Frequent diagnoses were encephali- tis, optic neuropathy, neuroretinitis, and Guillain–Barre ́ syndrome. Neurologic conditions showing characteristics of a direct viral pathomechanism showed a peak in infants and a second one in elder patients, and complications and neurologic sequelae were more frequent in these groups. Autoimmune-mediated conditions appeared mainly in patients over 20 years and tended to show longer latencies and better outcomes. Geospatial subgrouping of case reports from either India or Re ́union revealed diverging phenotypic trends (Re ́union: 88% direct viral vs. India: 81% autoimmune). ConclusionsDirect viral forms of Neuro-Chikungunya seem to occur particularly in infants and elderly patients, while autoimmune forms have to be also considered in middle-aged, previously healthy patients, especially after an asymptomatic interval. This knowledge will help to identify future Neuro-Chikungunya cases and to improve outcome especially in autoimmune-mediated conditions. The genetics of Chikungunya virus might play a key role in determining the course of neuropathogenesis. With further research, this could prove diagnostically significant.

Abstract Chikungunya is an emerging arbovirus that is characterized into four lineages. One of these, the Asian genotype, has spread rapidly in the Americas after its introduction in the Saint Martin island in October 2013. Unexpectedly, a new lineage, the East-Central-South African genotype, was introduced from Angola in the end of May 2014 in Feira de Santana (FSA), the second largest city in Bahia state, Brazil, where over 5,500 cases have now been reported. Number weekly cases of clinically confirmed CHIKV in FSA were analysed alongside with urban district of residence of CHIKV cases reported between June 2014 and October collected from the municipality’s surveillance network. The number of cases per week from June 2014 until September 2015 reveals two distinct transmission waves. The first wave ignited in June and transmission ceased by December 2014. However, a second transmission wave started in January and peaked in May 2015, 8 months after the first wave peak, and this time in phase with Dengue virus and Zika virus transmission, which ceased when minimum temperature dropped to approximately 15°C. We find that shorter travelling times from the district where the outbreak first emerged to other urban districts of FSA were strongly associated with incidence in each district in 2014 (R2).
The International Fetal and Newborn Growth consortium for the 21st century (INTERGROWTH-21st) was established to define optimal growth and development and the conditions required for this to occur.
We are delighted to announce that Sri Lanka has become the first country to adopt the INTERGROWTH-21st Preterm Standards.
Drs Leila Cheikh Ismail and Jane Hirst are currently introducing the Preterm Growth Standards through a series of workshops in Sri Lanka.

The EMPOWER Program (EMpowering Progress in Obstetric and Women's hEalth Research) is now accepting research proposals related to preeclampsia and other hypertensive disorders of pregnancy from young investigators in low resource settings. Letters of Intent are due November 15, 2015. Thereafter, projects deemed feasible will be invited to submit full applications by April 15, 2016. The grant recipient will be announced in October 2016 at the World Congress of the International Society for the Study of Hypertension in Pregnancy (ISSHP).
