Ultraviolet damage to the eye revisited: eye-sun protection factor (E-SPF®), a new ultraviolet protection label for eyewear.

Ultraviolet (UV) radiation potentially damages the skin, the immune system, and structures of the eye. A useful UV sun protection for the skin has been established. Since a remarkable body of evidence shows an association between UV radiation and damage to structures of the eye, eye protection is important, but a reliable and practical tool to assess and compare the UV-protective properties of lenses has been lacking. Among the general lay public, misconceptions on eye-sun protection have been identified. For example, sun protection is mainly ascribed to sunglasses, but less so to clear lenses. Skin malignancies in the periorbital region are frequent, but usual topical skin protection does not include the lids. Recent research utilized exact dosimetry and demonstrated relevant differences in UV burden to the eye and skin at a given ambient irradiation. Chronic UV effects on the cornea and lens are cumulative, so effective UV protection of the eyes is important for all age groups and should be used systematically. Protection of children's eyes is especially important, because UV transmittance is higher at a very young age, allowing higher levels of UV radiation to reach the crystalline lens and even the retina. Sunglasses as well as clear lenses (plano and prescription) effectively reduce transmittance of UV radiation. However, an important share of the UV burden to the eye is explained by back reflection of radiation from lenses to the eye. UV radiation incident from an angle of 135°-150° behind a lens wearer is reflected from the back side of lenses. The usual antireflective coatings considerably increase reflection of UV radiation. To provide reliable labeling of the protective potential of lenses, an eye-sun protection factor (E-SPF®) has been developed. It integrates UV transmission as well as UV reflectance of lenses. The E-SPF® compares well with established skin-sun protection factors and provides clear messages to eye health care providers and to lay consumers.

Statewide Economic Impacts of Disaster-Related Payments to Support Household and Private and Public Sector Recovery in Iowa, January 2010

There have been a multitude of programs providing assistance to the state of Iowa in the past 18 months. Springtime 2008 disasters resulted in tornado damage and widespread flood damage to large fractions of the state. In consequence, there was a very large flow of federal and state resources dedicated to assisting community and statewide recovery efforts. The nation was in recession as well and continued to be in recession through much of 2009. A sizeable amount of assistance found its way to Iowa under the American Recovery and Reinvestment Act of 2009 in the forms of infrastructure stimulus spending, income supports and other safety net spending for households, and stabilization assistance for essential public services like education. On top of that, the state of Iowa authorized the I Jobs program as an additional infrastructure development program, and as a jobs stimulus program. The total amount of spending for all types of programs, disaster or economic recovery related, is perhaps as high as $7.5 billion over the next few years.

Iowa Private Sector Prison Employment Works, Data Download, Iowa Department of Corrections, November 2006

This issue of the ICON Data Download describes highlights from the findings for the Iowa sample, which tracked 1,091 inmates who worked in private sector prison industries jobs and were released from prison between 1999 and 2001, and compared their results with similar offenders who had worked in either traditional prison industries, or other institutional jobs. All offenders were tracked through mid-2003. This results in a follow-up period of slightly less than two years up to four and one-half years.

Willigness to pay for long-term care coverage: the role of private information and self-insurance

Both public and private insurance for long-term care is undeveloped in some European countries such as in Spain and empirical evidence is still limited. This paper aims at exmining the determinants of the demand for Long Term Care (LTC) coverage in Spain using contingent valuation techniques. Our findings indicate that only one-fifth of the population is willing to pay to assure coverage decisions are significantly affected by private information asymmetry and housing tenure in giving rise to self-insurance reduces the probability of insurance being hypothetically purchased.

Off-label utilization of antidepressants

Rapport de synthèse : De nombreuses études sont effectuées sur les antidépresseurs avant leur mise sur le marché, puis des règles précises sont établies pour leur prescription dans des indications délimitées. Leur utilisation dans des indications «off-label » (hors indication officiellement admise) manque souvent de validation par des bases de données scientifiques et leur prescription se base le plus souvent sur un consensus proposé par des experts. Le but du présent travail a été d'étudier les habitudes de prescription de psychiatres d'hôpitaux en ce qui concerne les antidépresseurs, en comparant des patients traités pour une dépression et des troubles anxieux avec des patients recevant un traitement «off-label ». Pour cette étude, les données d'utilisation de médicaments sont celles recueillies lors de 6 jours de référence, entre avril 1999 et novembre 2001, à l'hôpital psychiatrique de Lausanne (Suisse) comprenant 98 lits. La prescription de médicaments chez 174 patients a été prise en compte. Tandis que le diagnostic n'influençait pas le choix entre des nouveaux et anciens antidépresseurs, les patients présentant un trouble anxieux avaient un risque 4.5 fois (p < 0.05) plus élevé et les patients présentant un autre diagnostic 8 fois plus élevé de recevoir une comédication antipsychotique, en comparaison avec des patients dont le diagnostic primaire était un trouble dépressif. De plus, les patients recevant comme comédication un hypnotique non-benzodiazépine avaient moins de risque que l'on prescrive un ancien antidépresseur (p < 0.05). Alors que les patients avec un trouble anxieux et ceux souffrant d'une dépression majeure recevaient un antidépresseur à des doses comparables, les patients répondant à une indication off-label étaient de préférence traités avec des doses plus faibles. Les résultats de cette étude suggèrent que les psychiatres d'hôpitaux développent des préférences en ce qui concerne le choix de la classe d'antidépresseurs, et qu'ils les utilisent alors aussi bien dans des indications reconnues que non-reconnues. Puis ils semblent adapter la dose et la comédication en tenant compte du diagnostic, ce qui confirme l'hypothèse initiale de l'étude,

Ambulatory blood pressure monitoring to assess antihypertensive therapy in private practice

Non-invasive ambulatory blood pressure monitoring has proved to be very useful in evaluating hypertensive patients. However, most previous studies were performed in specialised centres. Here the results of two trials are presented in which private physicians used ambulatory BP monitoring to assess the efficacy of antihypertensive drugs. The results were very similar to those observed previously in specialised clinics. In the individual patient, the level of ambulatory recorded pressure could not be predicted based on BP readings taken at the doctor's office. Also, the BP response to antihypertensive therapy was more reproducible when evaluated by ambulatory BP monitoring than by the doctor. Thus, the use of noninvasive ambulatory BP monitoring is also very appropriate in everyday practice for the management of hypertensive patients.
