Last week, Tech Times reported a wearable fitness tracker developed by Fitbit ended up saving a woman's life by alerting her to a dangerous health condition she was suffering from. The device showed an elevated heart rate and led to the discovery of a pulmonary embolism, which could have been fatal had it not been detected on time. But a new study suggests fitness trackers may not be completely reliable when it comes to monitoring heart rates. According to co-author Lisa Cadmus-Bertram, a kinesiologist at the University of Wisconsin, wearing a wristband tracker while exercising may alter the device's heart rate readings. "Heart rate is easiest to measure during rest, but once you start exercising, more variables come into play including sweat, which may have an effect," explains Cadmus-Bertram. The research, published April 11 in the Annals of Internal Medicine, offers evidence that fitness trackers are less accurate than an electrocardiograph in measuring heart rate during exercise. In an experiment, a joint team of scientists from the University of Wisconsin and Loras College compared four types of wristband trackers commonly used by fitness enthusiasts - the Fitbit Surge, the Basis Peak, the Fitbit Charge, and the Mio Fuse. The researchers tested them against each other and also in comparison with EKG readings. They enlisted the help of 40 volunteers - all healthy adults between 30 and 65 years of age - to wear the trackers, two on each arm. The four devices monitor heart rate with the help of a light-emitting diode that tracks light reflected by the wearer's skin to detect small changes in skin blood volume. While study participants remained at rest, the Fitbit Surge gave the closest readings to the EKG - known as the most accurate method of tracking heart rate. Readings taken by the Basis Peak - which coincidentally is the most expensive of the four devices and was voluntarily recalled last year after overheating issues caused burns in some users - were furthest off from the EKG, while measurements from the other two wrist-worn trackers fell in between. However, when the volunteers did a moderate-intensity exercise test and hopped up on a treadmill for 10 minutes at 65 percent of their maximum heart rate, the data reported by the monitors on the fitness trackers was inconsistent with the EKG readings. All the trackers showed a "relatively poor" performance, diverging from the EKG with as many as 41 beats per minute too slow and 39 beats per minute too fast. Moreover, the wristband trackers recorded discrepancies in measuring the same heart rate of the same person under the same conditions. Although the experiment found accuracy problems in the fitness trackers, Cadmus-Bertram says "they don't need to be perfectly accurate" to give wearers motivation for "a more active lifestyle." While researchers agree further studies are needed in order to determine whether the monitoring feature in these devices is sufficiently reliable "to help clinicians advise their patients about health issues," Cadmus-Bertram specifies there is "no reason for the general public not to use it for feedback and motivation." In response to the study results, Fitbit officials stated the company's products are not intended to be medical devices "but give other valuable wellness measurements not measured by an EKG, such as estimated maximum oxygen consumption during exercise, which can indicate cardiovascular fitness." © 2017 Tech Times, All rights reserved.

Using that nifty fitness monitor to keep track of your heart rate while you exercise? If you exercise while remaining still, it may work pretty well. If you move while exercising, not so much. A study published Monday in the Annals of Internal Medicine put four wearable fitness trackers to the test — both against one another and against the kind of electrocardiography monitor you’d probably encounter while taking a stress test in an doctor’s office. The results show that the wristband fitness trackers may be a fine gauge of how many steps you take. But when it comes to tracking changes to your heart rate that come with movement, these monitors don’t stack up, the authors found. The trackers tested in the study range in price from $57 (for the Mio Fuse) to $500 (for the Basis Peak). To measure heart rate, at least one of them uses light reflected from the skin to detect tiny changes in skin blood volume. Researchers from University of Wisconsin in Madison and Loras College in Dubuque, Iowa, had 40 healthy adults strap on four popular activity trackers, two on each arm. Study participants, ages 30 to 65, also were rigged up to an electrocardiograph, which uses leads in a chest strap to detect the wearer’s heart rate. For stationary subjects, the Fitbit Surge diverged least from the heart rate measurement taken by the electrocardiograph. Readings taken by the Basis Peak diverged the most. The Fitbit Charge and the Mio Fuse fell in between. But when the subjects were asked to exercise on a treadmill for 10 minutes at 65% of their maximum heart rate (a moderate-intensity pace), the performance of all the trackers was deemed “relatively poor,” according to the study. Compared with the electrocardiograph’s readings, the trackers reported heart rates that were as many as 41 beats per minute too slow and as many as 39 beats per minute too fast. Neither were these fitness monitors very reliable. When the researchers tested the “repeatability coefficient” — essentially, the degree to which a given tracker returned the same measurements for the same participant under the same conditions — the Fitbit Surge performed roughly as well as an electrocardiograph while subjects were at rest. But when study participants exercised, all four trackers returned heart rate readings that varied at least twice as much as did the electrocardiograph. Wristband activity trackers are gaining adherents among researchers as well as among fitness enthusiasts. But while the monitors may be good at measuring strides and at encouraging users to take more of them, their use by physicians and researchers may be premature, the study authors concluded. “More research is needed before we can confidently conclude that the monitoring feature for heart rate is sufficient to help clinicians advise their patients about health issues and conduct clinical trails that requires a high level of accuracy and reliability for heart rate measurement,” they wrote. Lisa Cadmus-Bertram, a University of Wisconsin kinesiologist who worked on the study, said the results shouldn’t prompt anyone to toss their tracker. "On the whole, fitness trackers still provide a tremendous amount of useful information to the average user who just wants some feedback to help them to increase their exercise level,” she said.

Numerous techniques have been employed to monitor humeral head translation due to its involvement with several shoulder pathologies. However, most of the techniques were not validated. The objective of this study is to compare the accuracy of manual digitization and contour registration in measuring superior translation of the humeral head. Eight pairs of cadaver scapulae and humerii bones were harvested for this study. Each scapula and humerus was secured in a customized jig that allowed for control of humeral head translations and a vise that permitted rotations of the scapula about three axes. Fluoroscopy was used to take images of the shoulder bones. Scapular orientation was manipulated in different positions while the humerus was at 90° of humeral elevation in the scapular plane. Humeral head translation was measured using the two methods and was compared to the known translation. Additionally, accuracy of the contour registration method to measure 2-D scapular rotations was assessed. The range for the root mean square (RMS) error for manual digitization method was 0.27. mm - 0.43. mm and the contour registration method had a RMS error ranging from 0.18. mm - 0.40. mm. In addition, the RMS error for the scapular angle rotation using the contour registration method was 2.4°. Both methods showed acceptable errors. However, on average, the contour registration method showed lesser measurement error compared to the manual digitization method. In addition, the contour registration method was able to show good accuracy in measuring rotation that is useful in 2-D image analysis. © 2009 Elsevier Ltd.

Cranial placodes are local thickenings of the vertebrate head ectoderm that contribute to the paired sense organs (olfactory epithelium, lens, inner ear, lateral line), cranial ganglia and the adenohypophysis. Here we use tissue grafting and dye injections to generated fate maps of the dorsal cranial part of the non-neural ectoderm for Xenopus embryos between neural plate and early tailbud stages. We show that all placodes arise from a crescent-shaped area located around the anterior neural plate, the pre-placodal ectoderm. In agreement with proposed roles of Six1 and Pax genes in the specification of a panplacodal primordium and different placodal areas, respectively, we show that Six1 is expressed uniformly throughout most of the pre-placodal ectoderm, while Pax6, Pax3, Pax8 and Pax2 each are confined to specific subregions encompassing the precursors of different subsets of placodes. However, the precursors of the vagal epibranchial and posterior lateral line placodes, which arise from the posteriormost pre-placodal ectoderm, upregulate Six1 and Pax8/Pax2 only at tailbud stages. Whereas our fate map suggests that regions of origin for different placodes overlap extensively with each other and with other ectodermal fates at neural plate stages, analysis of co-labeled placodes reveals that the actual degree of overlap is much smaller. Time lapse imaging of the pre-placodal ectoderm at single cell resolution demonstrates that no directed, large-scale cell rearrangements occur, when the pre-placodal region segregates into distinct placodes at subsequent stages. Our results indicate that individuation of placodes from the pre-placodal ectoderm does not involve large-scale cell sorting in Xenopus. © 2011 Elsevier Inc.

Online reading requires traditional and new comprehension skills and strategies, and these skills and strategies will have to be taught and supported, especially for young beginning readers. But how do elementary teachers go about doing this? Much of the research regarding teaching and supporting online reading comprehension has focused on older rather than younger readers. The significance of Internet Guided Reading is that it provides one successful instructional strategy for the primary classroom teacher that supports young children at various levels of proficiency with print and the Internet in learning to read informational texts on the Web. Internet Guided Reading effectively combines guided reading, modified reciprocal teaching, and online reading comprehension. © 2015 International Literacy Association.

Food availability is considered an important limiting factor in the breeding performance of marine birds, which exhibit restraint in reproductive life-history characteristics (e.g., delayed maturation, small clutch size, slow growth). Less well understood, however, is the extent to which taxonomic analogue species that breed in freshwater habitats are similarly regulated by food availability. Marsh-nesting Forster's Terns (Sterna forsteri) were studied from 2004 to 2008 at Horicon Marsh, a freshwater colony site in Wisconsin, USA, where reproductive success has been chronically poor. The adequacy of the food base to support a breeding colony of terns was evaluated (1) indirectly, through measures of breeding performance correlated with food availability during the egg-laying and incubation stages; and (2) directly, through a supplemental feeding experiment, conducted in 2004 and 2006, to determine whether nestling growth was limited by food availability. Clutch size, egg size, and adult body condition did not differ significantly among years, despite considerable annual fluctuation in environmental conditions and the rapid and extensive colonization of the wetland complex during the study period by a potential food competitor, American White Pelican (Pelecanus erythrorhynchos). Growth rates of chicks were ∼10% higher, on average, in 2006 than in 2004, but no difference was found in mean daily growth rates between food-supplemented and control chicks, nor did chick growth differ according to hatching order in the brood or hatching date. These results suggest that food availability is not a limiting factor during the breeding season for Forster's Terns at Horicon Marsh, the only actively managed breeding site remaining for this species in Wisconsin. © 2014 American Ornithologists' Union.

The concept of aromaticity has dramatically evolved and expanded to where it is no longer reserved for use in organic chemistry but is also useful in describing the bonding in many inorganic compounds. The aromaticity of inorganic rings arises from participation of s, p, d and f atomic orbitals to form delocalized σ, π, δ and φ molecular orbitals. This report describes the stability, structures and bonding of mainly covalent inorganic "sandwich" compounds or metallocenes in which aromatic, antiaromatic and nonaromatic inorganic rings, as well as those with multiple or conflicting aromaticity, are bonded primarily to the transition elements. Also included are some examples of ionic salt and covalent metallocenes of the main group and f-block elements with rings that exhibit other than only p orbital aromaticity. While many of the referenced compounds have been experimentally generated, computational methods play an important role in predicting the stability and ground state structures of several other hypothetical inorganic rings and the metallocenes produced from them. The theoretical studies also aid in defining the criteria that are used in determining the nature of compound aromaticity. © 2011 Elsevier B.V.
