The global abundance of N fertilizer has dramatically increased agricultural productivity. However, when N escapes to the atmosphere as ammonia (NH 3 ) gas, NH 3 loss can cause undesirable effects. In addition to a loss of a valuable resource, it can have negative impacts on air quality, ecosystem productivity, and human health. Animal production is the largest source of NH 3 emission in North ...

OBJECTIVE To explore methodological refinements in measuring health-related lost productivity and to assess the business implications of a full-cost approach to managing health. METHODS Health-related lost productivity was measured among 10 employers with a total of 51,648 employee respondents using the Health and Work Performance Questionnaire combined with 1,134,281 medical and pharmacy cla...

The introduction of biologics has changed treatment patterns as well as costs in patients with psoriasis. This study was performed to estimate direct and indirect costs of the psoriasis population in Sweden, and to analyse changes in costs between 2006 and 2009. The study population was identified in national registers. Direct costs included health care visits with primary psoriasis diagnoses i...

The work productivity loss due to ankylosing spondylitis (AS) has become subject of interest because of its socioeconomic impact. In addition to physical limitations, other variables seem to affect the productivity of those patients, who often withdraw early from the labor force. This review was aimed at identifying articles published in English, from January 2001 to December 2011, which assess...

Violence, a serious public health problem in Thailand, remains largely unknown for its economic costs. This study is a national-level economic cost-estimates of injury from interpersonal and self-directed violence for Thailand during 2005 using the World Health Organization-US Centers for Disease Control and Prevention's guidelines. Direct medical costs from self-directed violence totaled 569 m...

OBJECTIVE To estimate the impact of trends in smoking and obesity prevalence on productivity loss among petrochemical employees from 1980 to 2009. METHODS Smoking and obesity informations were collected during company physical examinations. Productivity loss was calculated as differential workdays lost between smokers and non-smokers, and obese and normal-weight employees. RESULTS During 19...

Droughts significantly impact land carbon uptake by reducing the gross primary productivity (GPP). Projections suggest an increase in severe and extreme droughts twenty-first century. Despite importance of on uptakes, it remains unclear about GPP responses under different drought severity its changes current climate changes. Using four state-of-the-science products, we showed that moderate (−1 ...
