Vibrio vulnificus has been identified as one of the main causative agents of foodborne disease associated with shellfish consumption. Infections of V. vulnificus increase during the summer months due to higher densities of the bacteria in warmer water and inappropriate handling of shellfish. In Florida, the daily harvest period is regulated to control the length of time between shellfish harvest and processing, and this harvest period has been recently reduced during the summer months to decrease the risk of foodborne disease. Adoption of this public health policy can affect the profitability and economic sustainability of wild oyster harvesters, especially in resource-dependent coastal communities. This study develops a dynamic and stochastic bioeconomic model to assess the impact of this policy on fishers’ harvest and revenues, and weighs that impact against the policy’s potential public health benefits. Our results show that fishers will experience reduced harvests early in the season due to the shorter harvest hours, but this initial loss is partially recouped later in the season as harvests remain high for longer than they would have if the policy were not in place. This study highlights the relationship between food safety interventions and management of fishery resources, and provides a comprehensive framework for evaluating the costs and benefits associated with such interventions.  相似文献

It is hypothesized that residents of neighborhoods with limited access to affordable and nutritious food face greater barriers to eating a healthy diet, which may in turn, result in worse health outcomes for them. Low-income elderly in urban areas may be uniquely affected by these so-called “food deserts” due to limited transportation options, strong attachments to local neighborhoods, fixed incomes, physical limitations in food shopping and meal preparation, and chronic health problems. Using the 2006, 2010, and 2014 waves of the Health and Retirement Study (HRS), the association between the food environment of elderly individuals living in urban Census tracts and their diet-related health was examined. Within urban areas, we find little evidence that food deserts negatively impact the health of lower income elderly individuals. Policies to address the needs of elderly residents of food deserts should be narrowly targeted and carefully justified.  相似文献

Abstract

Aims: This retrospective chart review examined the six-month migraine-related healthcare resource use (HRU) among European patients who had ≥4 migraine days per month and previously failed at least two prophylactic migraine treatments.

Methods: Neurologists, headache specialists, and pain specialists in France, Germany, Italy, and Spain who treated ≥10 patients with migraine in 2017 were recruited (April–June 2018) to extract anonymized patient-level data. Eligible physicians randomly selected charts of up to five adult patients with clinically-confirmed migraine, ≥4 migraine days in the month prior to the index date, and had previously failed at least two prophylactic migraine treatments. Treatment failure was defined as discontinuation due to lack of efficacy and/or tolerability. Demographic and disease characteristics as of the index date, and migraine-related HRU incurred during the 6-month study period, were recorded.

Results: A total of 104 physicians contributed 168 charts for patients (63% female). On average, patients were 38?years old and failed 2.3 prophylactic treatments as of the index date. During the study period, 83% of patients had ≥1 outpatient visit for migraine in the physician’s office, and 27% went to the ER/A&E. Approximately 5% of patients were hospitalized for migraine, with an average of one hospitalization and an average length of stay of 3 days. Approximately 39% of patients had ≥1 blood test, 22% had ≥1 magnetic resonance imaging, 17% had ≥1 electroencephalogram, and 13% had ≥1 computerized tomography scan. Visits to other healthcare providers were common.

Limitations: This study is subject to the limitations of chart review studies, such as errors in data entry.

Conclusions: Across four European countries, the HRU burden of migraine among patients who previously failed at least two prophylactic treatments was high, indicating a need for more effective prophylactic treatments to appropriately manage migraine and reduce the HRU burden attributable to this common disorder.  相似文献

Drawing on Dutch disease theory, we assess how the recent housing boom has contributed to a decline in China's manufacturing exports. Using Chinese city and enterprise panel data from 2004 to 2013, our analysis reveals that Dutch disease indeed exists and that the housing price increase has played a very important role in affecting China's manufacturing exports through two key channels: resource movement effect and spending effect. Specifically, this paper found that: (i) the housing price increase hindered labor flowing into China's manufacturing industry (resource movement effect) and caused higher inflation (spending effect); (ii) the housing boom clearly impeded China's manufacturing exports, especially after the outbreak of the global economic crisis in 2008; (iii) the impacts of the housing price increase on China's manufacturing exports were heterogenous, and were more significant for labor-intensive manufacturing businesses, businesses that were foreign owned, less R&D intensive, or located in the central and western regions.  相似文献

We evaluate the impact of Affordable Care Act Medicaid expansion on coverage, access to care, and self-reported health, for the vulnerable and chronically ill using data from the behavioral risk factor surveillance system (BRFSS). Using 5 years of post-reform data between 2014 and 2018 and a difference-in-differences identification strategy, we find that the Medicaid expansion improved coverage and access to care among both those with and without chronic conditions. While the effect sizes are mostly larger for those with a chronic condition, the differences in magnitude are not statistically significant. We also find statistically significant improvements in self-assessed health for those without chronic conditions. Finally, we find larger improvements in coverage and access to care among those with chronic conditions in states with higher-than-average pre-ACA uninsured rates for those with chronic conditions, though these coverage and access gains did not translate into health improvements for this group.  相似文献
