National data reveal that foot and toe symptoms are among the top 20 reasons patients ages 65-74 visit their physician. In the U.S., foot pain is considered a very common musculoskeletal symptom and occurs in such conditions as rheumatoid arthritis, diabetes, and gout, or with sprains, muscle strains, bruises, and fractures. Previous studies have determined a correlation between improper footwear and foot pain, but this research focused on small patient samples or disease specific studies.
Researchers from Boston University School of Public Health and the Institute for Aging Research at Hebrew SeniorLife enrolled 3,372 participants in the Framingham Foot Study. Participants were derived from 2 large population-based samples of residents from Framingham, Massachusetts. The first group was part of the Framingham Study Original Cohort (formed in 1948) and the Framingham Offspring Cohort (formed in 1972) that were originally studied for heart disease risk factors. The second group was a new population sample derived from census data and included subjects who were at least 50 years old and ambulatory who were added to increase participation by minority persons.
The Framingham Foot Study assessed 1,472 men and 1,900 women between 2002 and 2008. Subjects were asked if they experienced pain, aching, or stiffness in either or both feet. Data on specific areas of foot pain was identified in the nails, forefoot, hindfoot, heel, arch of the foot, and ball of the foot. Participants provided information on current and past shoewear across five age groups: 20-29 years, 30-44 years, 45-64 years, 65-74 years, and 75+ years. Shoewear was classified as good (low risk shoes including athletic and casual sneakers), average (mid risk shoes such as hard- or rubber-soled shoes, special shoes and work boots), and poor shoes (high-risk shoewear that lack support and sound structure, including high-heeled shoes, sandals, and slippers).

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
