Labor Induction versus Expectant Management in Low-Risk Nulliparous Women.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6186292
The New England Journal of Medicine; Grobman WA, Rice MM et. al.

Aug 8th, 2018 - The perinatal and maternal consequences of induction of labor at 39 weeks among low-risk nulliparous women are uncertain. In this multicenter trial, we randomly assigned low-risk nulliparous women who were at 38 weeks 0 days to 38 weeks 6 days of gestation to labor induction at 39 weeks 0 days to 39 weeks 4 days or to expectant management. The primary outcome was a composite of perinatal death ...

Proceedings of the National Academy of Sciences of the Un... Uhlemann AC, Dordel J et. al.

Apr 22nd, 2014 - During the last 2 decades, community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) strains have dramatically increased the global burden of S. aureus infections. The pandemic sequence type (ST)8/pulsed-field gel type USA300 is the dominant CA-MRSA clone in the United States, but its evolutionary history and basis for biological success are incompletely understood. Here, we us...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4211877
The New England Journal of Medicine; Spivak JL, Considine M et. al.

Aug 27th, 2014 - Polycythemia vera is the ultimate phenotypic consequence of the V617F mutation in Janus kinase 2 (encoded by JAK2), but the extent to which this mutation influences the behavior of the involved CD34+ hematopoietic stem cells is unknown. We analyzed gene expression in CD34+ peripheral-blood cells from 19 patients with polycythemia vera, using oligonucleotide microarray technology after correctin...

https://doi.org/10.1056/NEJMoa1404505
The New England Journal of Medicine; Baize S, Pannetier D et. al.

Apr 17th, 2014 - In March 2014, the World Health Organization was notified of an outbreak of a communicable disease characterized by fever, severe diarrhea, vomiting, and a high fatality rate in Guinea. Virologic investigation identified Zaire ebolavirus (EBOV) as the causative agent. Full-length genome sequencing and phylogenetic analysis showed that EBOV from Guinea forms a separate clade in relationship to t...

https://doi.org/10.1161/HYPERTENSIONAHA.117.09246
Hypertension (Dallas, Tex. : 1979); Tooher J, Thornton C et. al.

Sep 12th, 2017 - Hypertensive disorders of pregnancy are associated with vascular dysfunction in the pregnancy and an increased risk of long-term cardiovascular disease (CVD) in the mother. What remains to be understood is whether the length, severity of the disease, the treatment of hypertension in pregnancy, or the subtype of hypertensive disorders of pregnancy are significant predictors of future CVD. We und...

https://doi.org/10.1093/infdis/jiw530
The Journal of Infectious Diseases; Machalek DA, Chow EP et. al.

Nov 6th, 2016 - In Australia, high uptake of the quadrivalent human papillomavirus (4vHPV) vaccine has led to reductions in the prevalence of human papillomavirus (HPV) genotypes 6, 11, 16, and 18 in women and girls aged ≤25 years. We evaluated the impact of the program impact on HPV prevalence in unvaccinated male subjects. Sexually active heterosexual male subjects aged 16-35 years were recruited in 2014-201...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4036765
Emerging Infectious Diseases; Chu DK, Poon LL et. al.

May 26th, 2014 - We identified the near-full-genome sequence (29,908 nt, >99%) of Middle East respiratory syndrome coronavirus (MERS-CoV) from a nasal swab specimen from a dromedary camel in Egypt. We found that viruses genetically very similar to human MERS-CoV are infecting dromedaries beyond the Arabian Peninsula, where human MERS-CoV infections have not yet been detected.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4036761
Emerging Infectious Diseases; Memish ZA, Cotten M et. al.

May 26th, 2014 - We investigated a case of human infection with Middle East respiratory syndrome coronavirus (MERS-CoV) after exposure to infected camels. Analysis of the whole human-derived virus and 15% of the camel-derived virus sequence yielded nucleotide polymorphism signatures suggestive of cross-species transmission. Camels may act as a direct source of human MERS-CoV infection.

https://doi.org/10.1111/epi.12550
Epilepsia Fisher RS, Acevedo C et. al.

Apr 15th, 2014 - Epilepsy was defined conceptually in 2005 as a disorder of the brain characterized by an enduring predisposition to generate epileptic seizures. This definition is usually practically applied as having two unprovoked seizures >24 h apart. The International League Against Epilepsy (ILAE) accepted recommendations of a task force altering the practical definition for special circumstances that do ...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4091983
The New England Journal of Medicine; Gonçalves BP, Huang CY et. al.

May 8th, 2014 - Severe Plasmodium falciparum malaria is a major cause of death in children. The contribution of the parasite burden to the pathogenesis of severe malaria has been controversial. We documented P. falciparum infection and disease in Tanzanian children followed from birth for an average of 2 years and for as long as 4 years. Of the 882 children in our study, 102 had severe malaria, but only 3 had ...

The New England Journal of Medicine; von Gottberg A, de Gouveia L et. al.

Nov 11th, 2014 - In South Africa, a 7-valent pneumococcal conjugate vaccine (PCV7) was introduced in 2009 with a three-dose schedule for infants at 6, 14, and 36 weeks of age; a 13-valent vaccine (PCV13) replaced PCV7 in 2011. In 2012, it was estimated that 81% of 12-month-old children had received three doses of vaccine. We assessed the effect of vaccination on invasive pneumococcal disease. We conducted natio...

Clinical Infectious Diseases : an Official Publication Of... Johansson A, Lärkeryd A et. al.

Aug 6th, 2014 - The bacterium Francisella tularensis is recognized for its virulence, infectivity, genetic homogeneity, and potential as a bioterrorism agent. Outbreaks of respiratory tularemia, caused by inhalation of this bacterium, are poorly understood. Such outbreaks are exceedingly rare, and F. tularensis is seldom recovered from clinical specimens. A localized outbreak of tularemia in Sweden was investi...

Effects of red-cell storage duration on patients undergoing cardiac surgery.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5442442
The New England Journal of Medicine; Steiner ME, Ness PM et. al.

Apr 8th, 2015 - Some observational studies have reported that transfusion of red-cell units that have been stored for more than 2 to 3 weeks is associated with serious, even fatal, adverse events. Patients undergoing cardiac surgery may be especially vulnerable to the adverse effects of transfusion. We conducted a randomized trial at multiple sites from 2010 to 2014. Participants 12 years of age or older who w...
