10 Experiments at the Forefront of Sleep Science
As part of the team at Experiment.com, a crowdfunding platform for science, I get to talk to scientists all the time. I've been an insomniac and poor sleeper all my life, so I decided to run a Sleep Challenge Grant to launch a batch of sleep experiments together on the site.
Here's what I'm learning from 10 scientists at the forefront of sleep research:
Men who go to sleep late have more sex.
"Evening men," who naturally wake up later and go to sleep later, tend to have higher mating success but lower success in social settings like school or business. Dr. Christoph Randler wants to investigate whether there are clues fo...

Prevention of central nervous system sequelae in sickle cell disease without evidence from randomized controlled trials: the case for a team-based learning collaborative.
Authors: DeBaun MR, King AA
Abstract
Since 1998, the National Institutes of Health has funded 5 randomized controlled trials (RCTs) for primary and secondary prevention of strokes in children with sickle cell anemia (SCA). In a systematic fashion, these trials have significantly advanced the care of children with SCA. In the absence of an RCT, clinicians are often compelled to make decisions at the bedside, based on experience, observational studies, and principles of hematology. We will provide an initial example that describes how a team-based, learning collaborative developed a multisite standard care protocol w...

Shifting Spatial Neglect With Repeated Line Bisections: Possible Role of Lateralized Attentional Fatigue
Conclusions: The patient’s left-to-right shift with repeated trials suggests either fatigue from an attempted compensation for leftward inattention or habituation of a contralesional spatial attentional attraction, revealing contralesional left-sided neglect in both the left and right spaces. Future studies are needed to learn if other patients show similar or different deficits with repetition, and how best to treat them.

A new life for Lynkin after encephalocele surgery
When you meet Lynkin Bell, the first things you notice are her big personality and chubby cheeks. You might also see how she adores her brother Lukis and hamming it up for the camera. But you’d never guess that this playful 14-month-old from Texas wasn’t expected to survive, never mind talk, stand or play peekaboo like a pro.
And yet, thanks to her parents’ faith and persistence — and surgery at Boston Children’s Hospital — Lynkin can do all those things, and lots more, with the gusto befitting any toddler her age.
“It’s a miracle,” says Kaylen Gaston, Lynkin’s mom. “We were told so many times she wou...

7 medtech stories we missed this week: June 2, 2017
[Photo from unsplash.com]From Implandata receiving CE Marking to Inolife eyeing up-listing, here are 7 medtech stories we missed this week but thought were still worth mentioning.
1. Dextera seeks expanded indications for MicroCutter 5/80 stapler
Dextera Surgical announced in a June 1 press release that it has filed a 510(k) with the FDA for its MicroCutter 5/80 stapler. The company wants to expand the indications of the MicroCutter 5/80 for use in liver, pancreas, kidney and spleen surgeries. Currently, the staplers are used for transection and resection in multiple open minimally-invasive urologic, thoracic and pediatr...

Brief mindfulness meditation group training in aphasia: exploring attention, language and psychophysiological outcomes.
CONCLUSION & IMPLICATIONS: This is an emerging area of interest due to the potential low cost of MM training. Furthermore, MM is easily taught to patients, suggesting the possibility for widespread use in clinical practice as a supplement to existing language-focused interventions.

Motor control of handwriting in the developing brain: A review.
Abstract
This review focuses on the acquisition of writing motor aspects in adults, and in 5-to 12-year-old children without learning disabilities. We first describe the behavioural aspects of adult writing and dominant models based on the notion of motor programs. We show that handwriting acquisition is characterized by the transition from reactive movements programmed stroke-by-stroke in younger children, to an automatic control of the whole trajectory when the motor programs are memorized at about 10 years old. Then, we describe the neural correlates of adult writing, and the changes that could occur with learn...

CNS Summit 2017 Abstracts of Poster Presentations
Conclusion: This novel technology discriminates and quantifies subtle differences in behavior and neurological impairments in subjects afflicted with neurological injury/disease. KINARM assessments can be incorporated into multi-center trials (e.g., monitoring stroke motor recovery: NCT02928393). Further studies will determine if KINARM Labs can demonstrate a clinical effect with fewer subjects over a shorter trial period.
Disclosures/funding: Dr. Stephen Scott is the inventor of KINARM and CSO of BKIN Technologies.

Hypoxic-Ischemic Encephalopathy and Other Neonatal Encephalopathies
ABSTRACTPURPOSE OF REVIEWNeonatal encephalopathy is the most common condition in neonates encountered by child neurologists. The etiology is most often global hypoxia-ischemia due to failure of cerebral perfusion to the fetus caused by uterine, placental, or umbilical cord compromise prior to or during delivery. Other etiologies of neonatal encephalopathy include ischemic stroke and intracranial hemorrhage, infection, developmental anomalies, and inborn errors of metabolism.RECENT FINDINGSTherapeutic hypothermia is standard of care for the treatment of neonatal encephalopathy presumed to be caused by hypoxia-ischemia. The ...

Morphological and Whole-Word Semantic Processing Are Distinct: Event Related Potentials Evidence From Spoken Word Recognition in Chinese
In conclusion, the present study provides electrophysiological evidence of the dissociation of morphological and whole-word semantic processing in Chinese spoken word processing. The results identified a central-anterior morphological N400 effect when morphemic meaning conflicts with whole-word semantics, in addition to a classic semantic N400 effect with significantly reduced amplitude in central-parietal areas. Our results also showed that the morphological N400 effect is negatively correlated with reading ability. These results demonstrate the important role of morphological processing in Chinese spoken word recognition...

Intra-arterial Administration of Human Umbilical Cord Blood Derived Cells Inversed Learning Asymmetry Resulting From Focal Brain Injury in Rat
Conclusions: Intraarterial infusion of HUCB-derived cells inversed lateralized performance of learning task resulting from focal brain damage. The inversion was not visible in any other of the used motor as well as cognitive tests. The observed behavioral effect of cell infusion was also not related to the range of the brain damage. Our findings contribute to describing the effects of systemic treatment with the HUCB-derived cells on functional recovery following focal brain injury.
