- Hydroxycinnamic acids are the most widely distributed phenolic acids in plants. Broadly speaking, they can be defined as compounds derived from cinnamic acid. They are present at high concentrations in many food products, including fruits, vegetables, tea, cocoa, and wine. A diet rich in hydroxycinnamic acids is thought to be associated with beneficial health effects such as a reduced risk of cardiovascular disease. The impact of hydroxycinnamic acids on health depends on their intake and pharmacokinetic properties. This review discusses their chemistry, biosynthesis, natural sources, dietary intake, and pharmacokinetic properties.

- Following on from the NASA twins’ study, there has been a tremendous interest in the use of omics techniques in spaceflight. Individual space agencies, NASA's GeneLab, JAXA's ibSLS, and the ESA-funded Space Omics Topical Team and the International Standards for Space Omics Processing (ISSOP) groups have established several initiatives to support this growth. Here, we present recommendations from the Space Omics Topical Team to promote standard application of space omics in Europe. We focus on four main themes: i) continued participation in and coordination with international omics endeavors, ii) strengthening of the European space omics infrastructure including workforce and facilities, iii) capitalizing on the emerging opportunities in the commercial space sector, and iv) capitalizing on the emerging opportunities in human subjects research.

- ObjectiveTo synthesize the best available evidence on prognosis after sport concussion.Data SourcesMEDLINE and other databases were searched (2001–2012) with terms including “craniocerebral trauma” and “sports.” Reference lists of eligible articles were also searched.Study SelectionRandomized controlled trials and cohort and case-control studies were selected according to predefined criteria. Studies had to have a minimum of 30 concussion cases.Data ExtractionEligible studies were critically appraised using a modification of the Scottish Intercollegiate Guidelines Network (SIGN) criteria. Two reviewers independently reviewed and extracted data from accepted studies into evidence tables.Data SynthesisEvidence was synthesized qualitatively according to modified SIGN criteria, and studies were categorized as exploratory or confirmatory based on the strength of their design and evidence. After 77,914 records were screened, 52 articles were eligible for this review, and 24 articles (representing 19 studies) with a low risk of bias were accepted. Our findings are based on exploratory studies of predominantly male football players at the high school, collegiate, and professional levels. Most athletes recover within days to a few weeks, and American and Australian professional football players return to play quickly after mild traumatic brain injury. Delayed recovery appears more likely in high school athletes, in those with a history of previous concussion, and in those with a higher number and duration of postconcussion symptoms.ConclusionsThe evidence concerning sports concussion course and prognosis is very preliminary, and there is no evidence on the effect of return-to-play guidelines on prognosis. Our findings have implications for further research. Well-designed, confirmatory studies are urgently needed to understand the consequences of sport concussion, including recurrent concussion, across different athletic populations and sports.

- ObjectiveTo synthesize the best available evidence on return to work (RTW) after mild traumatic brain injury (MTBI).Data SourcesMEDLINE and other databases were searched (2001–2012) with terms including “craniocerebral trauma” and “employment.” Reference lists of eligible articles were also searched.Study SelectionControlled trials and cohort and case-control studies were selected according to predefined criteria. Studies had to assess RTW or employment outcomes in at least 30 MTBI cases.Data ExtractionEligible studies were critically appraised using a modification of the Scottish Intercollegiate Guidelines Network criteria. Two reviewers independently reviewed and extracted data from accepted studies into evidence tables.Data SynthesisEvidence was synthesized qualitatively according to modified Scottish Intercollegiate Guidelines Network criteria and prioritized according to design as exploratory or confirmatory. After 77,914 records were screened, 299 articles were found eligible and reviewed; 101 (34%) of these with a low risk of bias were accepted as scientifically admissible, and 4 of these had RTW or employment outcomes. This evidence is preliminary and suggests that most workers RTW within 3 to 6 months after MTBI; MTBI is not a significant risk factor for long-term work disability; and predictors of delayed RTW include a lower level of education (<11y of formal education), nausea or vomiting on hospital admission, extracranial injuries, severe head/bodily pain early after injury, and limited job independence and decision-making latitude.ConclusionsOur findings are based on preliminary evidence with varied patient characteristics and MTBI definitions, thus limiting firm conclusions. More well-designed studies are required to understand RTW and sustained employment after MTBI in the longer term (≥2y post-MTBI).

- This review focuses on recent advances in our understanding of the complex biosynthetic pathways and diverse biological activities of naturally occurring xanthones. The biosynthesis section covers studies published from 1989 to 2008 on xanthone production in plants and fungi, while the bioactivity review presents tabulated activities of more than 250 xanthones described in studies published from 2001 to 2008, together with structural information and indications of their wide-ranging potential uses as pharmacological tools. A large number of relevant papers have been published on these subjects (128 cited here), illustrating the diversity of the xanthones and their possible uses.

- BACKGROUND: Insulin-like growth factor 1 (IGF-1) is a mitogenic hormone involved in many processes such as growth, metabolism, angiogenesis and differentiation. After very preterm birth, energy demands increase while maternal supplies of nutrients and other factors are lost and the infant may become dependent on parenteral nutrition for weeks. Low postnatal IGF-1 concentrations in preterm infants are associated with poor weight gain, retinopathy of prematurity (ROP) and other morbidities. We will describe the process by which we aim to develop supplementation with recombinant human (rh) IGF-1 and its binding protein rhIGFBP-3 as a possible therapy to promote growth and maturation and reduce morbidities in extremely preterm infants.METHODS: In order to calculate a dose of IGF-1 tolerated by neonates, a pharmacokinetic study of transfusion with fresh frozen plasma was performed, which provided a relatively low dose of IGF-1, (on average 1.4 µg/kg), that increased serum IGF-1 to levels close to those observed in fetuses and preterm infants of similar GAs. Thereafter, a Phase I 3 hours IV infusion of rhIGF-1/rhIGFBP-3 was conducted in 5 infants, followed by a Phase II study with four sections (A-D). In the Phase II, sections A-D studies, time on infusion increased and younger gestational ages were included.RESULTS: IV infusion increased IGF-1 but with short half-life (0.5h) implying a need for continuous infusion. In order to obtain in utero levels of IGF-I, the dose was increased from 100 to 250 µg/kg/24 h and the infusion was prolonged from 3 weeks postnatal age until a postmenstrual age of 29 weeks and 6 days.CONCLUSION: The purpose has been to ensure high-quality research into the development of a new drug for preterm infants. We hope that our work will help to establish a new standard for the testing of medications for preterm infants.

- ObjectiveTo synthesize the best available evidence regarding the impact of nonsurgical interventions on persistent symptoms after mild traumatic brain injury (MTBI).Data SourcesMEDLINE and other databases were searched (2001–2012) with terms including “rehabilitation.” Inclusion criteria were original, peer-reviewed research published in English and other languages. References were also identified from the bibliographies of eligible articles.Study SelectionControlled trials and cohort and case-control studies were selected according to predefined criteria. Studies had to have a minimum of 30 MTBI cases and assess nonsurgical interventions using clinically relevant outcomes such as self-rated recovery.Data ExtractionEligible studies were critically appraised using a modification of the Scottish Intercollegiate Guidelines Network (SIGN) criteria. Two reviewers independently reviewed each study and extracted data from the admissible studies into evidence tables.Data SynthesisThe evidence was synthesized qualitatively according to the modified SIGN criteria. Recommendations were linked to the evidence tables using a best-evidence synthesis. After 77,914 records were screened, only 2 of 7 studies related to nonsurgical interventions were found to have a low risk of bias. One studied the effect of a scheduled telephone intervention offering counseling and education on outcome and found a significantly better outcome for symptoms (6.6 difference in adjusted mean symptom score; 95% confidence interval, 1.2–12.0), but no difference in general health outcome at 6 months after MTBI. The other was a randomized controlled trial of the effectiveness of 6 days of bed rest on posttraumatic complaints 6 months postinjury, compared with no bed rest, and found no effect.ConclusionsSome evidence suggests that early, reassuring educational information is beneficial after MTBI. Well-designed intervention studies are required to develop effective treatments and improve outcomes for adults and children at risk for persistent symptoms after MTBI.
