Localized surface plasmon resonance (LSPR) constitutes a versatile technique for biodetection exploiting the sensitivity of plasmonic nanostructures to small changes in refractive index. The optical shift in the LSPR band caused by molecular in-teractions in the vicinity of the nanostructures are typically < 5 nm and can readily be detected using a spectrophotometer. Widespread use of LSPR based sensors require cost effective devices and would benefit from sensing schemes that enables use of very simple spectrophotometers or even naked eye detection...

Evidence from Sierra Leone reveals the significant limitations of big data in disease detection and containment efforts. Early in the 2014-2016 Ebola epidemic in West Africa, media heralded HealthMap's ability to detect the outbreak from newsfeeds. Later, big data-specifically, call detail record (CDR) data collected from millions of cell phones-was hyped as useful for stopping the disease by tracking contagious people. It did not work. In this article, I trace the causes of big data's containment failures...

The ever-increasing speed and scope of human mobility by international air travel has led to a global transport network for infectious diseases with the potential to introduce pathogens into non-endemic areas, and to facilitate rapid spread of novel or mutated zoonotic agents.Robust national emergency preparedness is vital to mitigate the transmission of infectious diseases agents domestically and to prevent onward spread to other countries. Given the complex range of stakeholders who respond to an infectious disease threat being transmitted through air travel, it is important that protocols be tested and practised extensively in advance of a real emergency...

BACKGROUND: Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer with limited treatment options at advanced stages. There is a paucity of data available regarding the impact of MCC and its management on patients' lives. This study aimed to address this gap by interviewing patients with metastatic MCC entering a trial of an immunotherapy (avelumab). METHODS: In a single-arm, open-label, international, phase 2 trial in patients with stage IV, chemotherapy-refractory, histologically confirmed MCC, patients were invited to participate in semi-structured phone interviews...

Focal adjustment and zooming are universal features of cameras and advanced optical systems. Such tuning is usually performed longitudinally along the optical axis by mechanical or electrical control of focal length. However, the recent advent of ultrathin planar lenses based on metasurfaces (metalenses), which opens the door to future drastic miniaturization of mobile devices such as cell phones and wearable displays, mandates fundamentally different forms of tuning based on lateral motion rather than longitudinal motion...

Background: Chronic rhinitis, pharyngitis and sinusitis are common health problems with a significant impact on public health, and are suspected to be influenced by ageing factors. Nasal inhalation with thermal water may be used to reduce symptoms, inflammation and drug intake. A pre-post clinical study was conducted in 183 consecutive adult and elderly patients with chronic rhinitis, pharyngitis or sinusitis, to evaluate whether thermal water nasal inhalations could improve their symptoms, clinical signs and rhinomanometry measurements, and influence inflammatory biomarkers levels in nasal epithelial cells...

Cell phone use has been implicated in driver distraction and motor vehicle crashes, and more recently has been associated with distracted pedestrians. There are limited data on interventions aimed at this important public health issue. We hypothesized that the use of a visual intervention near street crossings would decrease the frequency of distracted behaviors of pedestrians. We performed a prospective observational cohort study examining painted sidewalk stencils reading, "Heads Up, Phones Down" as an intervention to decrease cell phone distractions amongst pedestrians...

Smartphones, tablets, and other personal electronic devices have become ubiquitous in Americans' daily lives. These devices are used by people throughout the day, including while preparing food. For example, a device may be used to look at recipes and therefore be touched multiple times during food preparation. Previous research has indicated that cell phones can harbor bacteria, including opportunistic human pathogens such as Staphylococcus and Klebsiella spp. This investigation was conducted with data from the 2016 Food Safety Survey (FSS) and from subsequent focus groups to determine the frequency with which consumers use personal electronic devices in the kitchen while preparing food, the types of devices used, and hand washing behaviors after handling these devices...
