Study of the dimensions of the anterior chamber of the human eye. II. Influence of ametropias

peer reviewedFollowing their work on the eminctropc. the authors report on an investigation of 210 amelropes. They conclude that the anterior chamber is shallower in the hvpermetrope. and deeper in the myope, than in the emmet rope. There is a mathematical relationship between the degree of ametropia and the depth of the anterior chamber in uncomplicated cases, but not in complicated myopia, nor in ttni-ocular myopia. There is no relationship between the refractive error and the diameter and curvature of of the cornea. © 1962 S. Karger AG, Basel

Silicon for prevention, cure and care: A technology toolbox of wearables at the dawn of a new health system

Our increasing life expectancy also implies that many of us will be suffering from one or more chronic illnesses during a larger part of our lives. Medical-grade wearables have the grand promise and the largely untapped potential to become a cornerstone technology in the care cycle. For chronic patients, tools are needed that improve the risk stratification, follow-up and management and are able to monitor disease progression and prevent relapse. Aside from the already existing cardiac rhythm monitoring patches (1), studies with emerging wearable sensors are aim to track congestive heart failure (2), sleep apnea and hypertension. In these care-focused devices, quality of sensing comes first, followed by miniaturization and power autonomy. A massive opportunity for wearable sensing concerns behavior change. Frictionless technology, personalized algorithms/feedback and power autonomy are key requirements for widespread user adoption in this space. cop. 2015 IEEE

Outcome and hospitalization costs after aneurysmal subarachnoid hemorrhage : a single center retrospective analysis

Aneurysmal subarachnoid hemorrhage (aSAH) has a highly variable clinical outcome. Extended ICU and hospital stay often result in increased healthcare related costs. This study aimed to examine the relationship between aSAH severity, hospital costs and functional outcome in patients who required urgent or semi-urgent endovascular repair. Patients treated with endovascular repair after experiencing aSAH from January 2017 until September 2018 were included in this retrospective single center study. aSAH severity upon admission was classified by the World Federation of Neurosurgical Societies (WFNS) grade, dichotomized into WFNS grade 1-2, 'low grade aSAH' and WFNS grade 3-5, 'high grade aSAH'. Functional outcome was assessed at ICU discharge and 1 year post aSAH by utilizing the modified Rankin Scale (mRS) and converted to quality adjusted life years (QALY) for the latter time point. Healthcare related costs during index hospital stay were analyzed. A total of 69 patients were included with 44 (63,8%) suffering from low grade aSAH and 25 (36,2%) from high grade aSAH. Median utility scores at 1 year were 0,93 (IQR 0,83-0,93) for low grade aSAH and 0,42 (IQR 0-0,83) for high grade aSAH (p<0,001). Mean total costs were 56.150 euro (IQR 25.572-62.060) in high grade and 26.288 euro (IQR 18.893-29.993) in low grade aSAH (p=0,003). Cost per 0.1 QALY gain in high grade aSAH was 13.233 euro (IQR 2.803-23.072) and higher than in low grade aSAH 3.497 euro (IQR 2.200-3.344) (p=0,027). Short term healthcare related costs strongly depend on aSAH severity. ICU stay and ICU related complications were important cost driving factors. High grade aSAH is also accompanied by lower functional outcomes at 1 year and decreased cost-effectiveness in comparison to low grade aSAH
