Wearable health monitoring: wave of the future or waste of time?

Background: Atrial fibrillation is responsible for over 400,000 hospitalizations in the United States (US) each year. This costs the US health system over 4 billion each year. New smartwatches can constantly monitor pulse, oxygen saturation, and even heart rhythm.

Synthetic and practical reconstructions of SST and seawater pH using the novel multiproxy SMITE method.

Geochemical proxies of sea surface temperature (SST) and seawater pH (pHsw) in scleractinian coral skeletons are valuable tools for reconstructing tropical climate variability. However, most coral skeletal SST and pHsw proxies are univariate methods that are limited in their capacity to circumvent non-climate-related variability. Here we present a novel multivariate method for reconstructing SST and pHsw from the geochemistry of coral skeletons.

A concerning trend in geriatric pharmacy that merits evidence-based intervention.

The effects of polypharmacy on geriatric populations are an emerging concern that merits more exploration. The primary goal of this review was to evaluate the current body of knowledge on polypharmacy and explore the preventive and corrective measures to avoid negative outcomes. Even if a medication has an appropriate indication, polypharmacy in the geriatric population is associated with an increased risk of drug-drug or drug-condition interactions.

Assessment of Natural Sunlight Protection Provided by 10 High-SPF Broad-Spectrum Sunscreens and Sun-Protective Fabrics.

In 1978, the FDA Advisory Panel proposed both indoor and natural sunlight SPF testing methods but reverted to indoor testing only in 1993. Today's sunscreen sun protection and broad-spectrum claims are based on mandated clinical tests using solar simulators and in vitro spectrophotometers. This research evaluated the protection of 10 high-SPF (30-110), broad-spectrum sunscreen products, as well as 6 sun-protective fabrics against natural sunlight in Arequipa, Peru.

A comparison of handheld ultrasound versus traditional ultrasound for acquisition of RUSH views in healthy volunteers.

Few studies evaluate the use of handheld ultrasound devices for point-of-care ultrasonography in the emergency department. We hypothesized that image acquisition time and image quality are similar between a handheld device and a traditional device. We compared these 2 types of devices in healthy, non-pregnant adults with using a crossover non-inferiority design while acquiring Rapid Ultrasound for Shock and Hypotension (RUSH) view.
