Objectives: To provide an overview of the health status of young US workers across four domains: functional health, physical and psychological health, health behavior, and health care utilization. Methods: Pooled data from the 2004 to 2010 National Health Interview Survey were analyzed for 11,279 US workers aged 18 to 24 years, representing an estimated 16.9 million workers annually. Thirty-nine health indicators were examined and compared across nine occupational groups. Results: Compared with other occupational groups, craft workers and laborers and helpers had the highest prevalence of risky health behaviors, including current smoking and risky drinking, as well as fewer reported visits to a primary care physician in the past year. Conclusions: Young workers engage in risky health behaviors, and may benefit from targeted workplace interventions to mitigate the potentially negative long-term effects on health and well-being.

Abstract: Having demonstrated significant and persistent adverse changes in pulmonary function for asthmatics after 1h exposure to brevetoxins in Florida red tide (Karenia brevis bloom) aerosols, we assessed the possible longer term health effects in asthmatics from intermittent environmental exposure to brevetoxins over 7 years. 125 asthmatic subjects were assessed for their pulmonary function and reported symptoms before and after 1h of environmental exposure to Florida red tide aerosols for up to 11 studies over seven years. As a group, the asthmatics came to the studies with normal standardized percent predicted pulmonary function values. The 38 asthmatics who participated in only one exposure study were more reactive compared to the 36 asthmatics who participated in ≥4 exposure studies. The 36 asthmatics participating in ≥4 exposure studies demonstrated no significant change in their standardized percent predicted pre-exposure pulmonary function over the 7 years of the study. These results indicate that stable asthmatics living in areas with intermittent Florida red tides do not exhibit chronic respiratory effects from intermittent environmental exposure to aerosolized brevetoxins over a 7 year period.

Context: During a Florida red tide, brevetoxins (PbTxs) produced by Karenia brevis become aerosolized and can cause both immediate and prolonged airway symptoms in humans, especially in those with preexisting airway disease (e.g., asthma). Although environmental monitoring indicates that toxins remain airborne for up to 4 consecutive days, there is little information on airway responses after multiple-day exposures. Objectives: To delineate putative mechanisms leading to pulmonary dysfunction after PbTx exposure, we studied airway responses before and after multiple exposures to aerosol PbTx-3, the most potent PbTx produced, in nonallergic (healthy) and in allergic sheep, which serve as a surrogate for patients with compromised airways. Methods: Both groups were exposed to 20 breaths of increasing concentrations of PbTx-3 (30--300 pg/mL) for 4 consecutive days. Airway responsiveness to carbachol (1 and 8 days after) and airway inflammation as assessed by bronchoalveolar lavage (0 and 7 days after) were measured. Results: Both groups developed airway hyperresponsiveness (AHR) 1 day after challenge; the severity was concentration dependent and more severe in the allergic group. AHR remained after 8 days, but the difference in the severity between the groups was lost. Both groups developed an inflammatory response after exposure to 300 pg/mL PbTx-3. Immediately after exposure, lung neutrophilia was prominent. This neutrophilia persisted for 7 days in addition to increases in total cells and macrophages. Conclusion: Repeated exposures to PbTx-3 result in prolonged AHR and lung inflammation. These pathophysiologic responses could be underlying contributors to the prolonged respiratory symptoms in humans after red tides. [ABSTRACT FROM AUTHOR]

Abstract: This paper reviews the literature describing research performed over the past decade on the known and possible exposures and human health effects associated with Florida red tides. These harmful algal blooms are caused by the dinoflagellate, Karenia brevis, and similar organisms, all of which produce a suite of natural toxins known as brevetoxins. Florida red tide research has benefited from a consistently funded, long-term research program, that has allowed an interdisciplinary team of researchers to focus their attention on this specific environmental issue—one that is critically important to Gulf of Mexico and other coastal communities. This long-term interdisciplinary approach has allowed the team to engage the local community, identify measures to protect public health, take emerging technologies into the field, forge advances in natural products chemistry, and develop a valuable pharmaceutical product. The review includes a brief discussion of the Florida red tide organisms and their toxins, and then focuses on the effects of these toxins on animals and humans, including how these effects predict what we might expect to see in exposed people.

Abstract: Blooms of the toxic dinoflagellate, Karenia brevis, produce potent neurotoxins in marine aerosols. Recent studies have demonstrated acute changes in both symptoms and pulmonary function in asthmatics after only 1h of beach exposure to these aerosols. This study investigated if there were latent and/or sustained effects in asthmatics in the days following the initial beach exposure during periods with and without an active Florida red tide. Symptom data and spirometry data were collected before and after 1h of beach exposure. Subjects kept daily symptom diaries and measured their peak flow each morning for 5 days following beach exposure. During non-exposure periods, there were no significant changes in symptoms or pulmonary function either acutely or over 5 days of follow-up. After the beach exposure during an active Florida red tide, subjects had elevated mean symptoms which did not return to the pre-exposure baseline for at least 4 days. The peak flow measurements decreased after the initial beach exposure, decreased further within 24h, and continued to be suppressed even after 5 days. Asthmatics may continue to have increased symptoms and delayed respiratory function suppression for several days after 1h of exposure to the Florida red tide toxin aerosols. [Copyright &y& Elsevier]

Background: Microbial water-quality indicators, in high concentrations in sewage, are used to determine whether water is safe for recreational purposes. Recently, the use of these indicators to regulate recreational water bodies, particularly in sub/tropical recreational marine waters without known sources of sewage, has been questioned. The objectives of this study were to evaluate the risk to humans from exposure to subtropical recreational marine waters with no known point source, and the possible relationship between microbe densities and reported symptoms in human subjects with random-exposure assignment and intensive individual microbial monitoring in this environment.Methods: A total of 1303 adult regular bathers were randomly assigned to bather and non-bather groups, with subsequent follow-up for reported illness, in conjunction with extensive environmental sampling of indicator organisms (enterococci).Results: Bathers were 1.76 times more likely to report gastrointestinal illness [95% confidence interval (CI) 0.94-3.30; P = 0.07]; 4.46 times more likely to report acute febrile respiratory illness (95% CI 0.99-20.90; P = 0.051) and 5.91 times more likely to report a skin illness (95% CI 2.76-12.63; P < 0.0001) relative to non-bathers. Evidence of a dose-response relationship was found between skin illnesses and increasing enterococci exposure among bathers [1.46 times (95% CI 0.97-2.21; P = 0.07) per increasing log(10) unit of enterococci exposure], but not for gastrointestinal or respiratory illnesses.Conclusions: This study indicated that bathers may be at increased risk of several illnesses relative to non-bathers, even in the absence of any known source of domestic sewage impacting the recreational marine waters. There was no dose-response relationship between gastroenteritis and increasing exposure to enterococci, even though many current water-monitoring standards use gastroenteritis as the major outcome illness.

Background: In previous studies we demonstrated statistically significant changes in reported symptoms for lifeguards, general beach goers, and persons with asthma, as well as statistically significant changes in pulmonary function tests (PFTs) in asthmatics, after exposure to brevetoxins in Florida red tide (Karenia brevis bloom) aerosols. Objectives: In this study we explored the use of different methods of intensive ambient and personal air monitoring to characterize these exposures to predict self-reported health effects in our asthmatic study population. Methods: We evaluated health effects in 87 subjects with asthma before and after 1 hr of exposure to Florida red tide aerosols and assessed for aerosolized brevetoxin exposure using personal and ambient samplers. Results: After only 1 hr of exposure to Florida red tide aerosols containing brevetoxin concentrations > 57 ng/m3, asthmatics had statistically significant increases in self-reported respiratory symptoms and total symptom scores. However, we did not see the expected corresponding changes in PFT results. Significant increases in self-reported symptoms were also observed for those not using asthma medication and those living ⩾ 1 mile from the coast. Conclusions: These results provide additional evidence of health effects in asthmatics from ambient exposure to aerosols containing very low concentrations of brevetoxins, possibly at the lower threshold for inducing a biologic response (i.e., toxicity). Consistent with the literature describing self-reported symptoms as an accurate measure of asthmatic distress, our results suggest that self-reported symptoms are a valuable measure of the extent of health effects from exposure to aerosolized brevetoxins in asthmatic populations.

SMOKING cessation , *SMOKING , *TOBACCO use , *CIGARETTE smokers , *OCCUPATIONAL diseases , *EPIDEMIOLOGY - Abstract
Objective: Among workers in dusty occupations, tobacco use is particularly detrimental to health because of the potential synergistic effects of occupational exposures (for example, asbestos) in causing disease. This study explored the prevalence of smoking and the reported smoking cessation discussion with a primary healthcare provider (HCP) among a representative sample of currently employed US worker groups. Methods: Pooled data from the 1997-2003 National Health Interview Survey (NHIS) were used to estimate occupation specific smoking rates (n= 135 412). The 2000 NHIS Cancer Control Module was used to determine (among employed smokers with HCP visits) the prevalence of being advised to quit smoking by article for occupation (n = 3454). Results: The average annual prevalence of current smoking was 25% in all workers. In 2000, 84% of smokers reported visiting an HCP during the past 12 months; 53% reported being advised by their physician to quit smoking (range 42%-66% among 30 occupations). However, an estimated 10.5 million smokers were not advised to quit smoking by their HCP. Workers with potentially increased occupational exposure to dusty of Miami School of " work environments (including asbestos, silica, particulates, etc), at high risk for occupational lung disease and with high smoking prevalence, had relatively low reported discussions with an HCP about smoking cessation, Epidemiology and Public including farm workers (30% overall smoking prevalence; 42% told to quit), construction and extractive trades (39%; 46%), and machine operators/tenderers (34%; 44%). Conclusion: The relatively low reported prevalence of HCP initiated smoking cessation discussion, particularly among currently employed workers with potentially synergistic occupational exposures and high current smoking prevalence, needs to be addressed through educational campaigns targeting physicians and other HCPs.

The article discusses the survey conducted by the National Health Interview Survey (NHIS) concerning the smoking rate trends of blue and white-collar workers in the U.S. The NHIS is a nationally representative survey of the American civilian population. Smoking and current occupational status were assessed over the survey periods 1987 to 1994 and 1997 to 2004. The development of effective smoking prevention strategies specifically targeting the blue-collar groups is warranted. The results of the survey are also emphasized in the article.

RED tide , *SHELLFISH , *TOXINS , *ASTHMATICS , *OBSTRUCTIVE lung diseases - Abstract
Abstract: Human exposure to Florida red tides formed by Karenia brevis, occurs from eating contaminated shellfish and inhaling aerosolized brevetoxins. Recent studies have documented acute symptom changes and pulmonary function responses after inhalation of the toxic aerosols, particularly among asthmatics. These findings suggest that there are increases in medical care facility visits for respiratory complaints and for exacerbations of underlying respiratory diseases associated with the occurrence of Florida red tides. This study examined whether the presence of a Florida red tide affected the rates of admission with a respiratory diagnosis to a hospital emergency room in Sarasota, FL. The rate of respiratory diagnoses admissions were compared for a 3-month time period when there was an onshore red tide in 2001 (red tide period) and during the same 3-month period in 2002 when no red tide bloom occurred (non-red tide period). There was no significant increase in the total number of respiratory admissions between the two time periods. However, there was a 19% increase in the rate of pneumonia cases diagnosed during the red tide period compared with the non-red tide period. We categorized home residence zip codes as coastal (within 1.6km from the shore) or inland (>1.6km from shore). Compared with the non-red tide period, the coastal residents had a significantly higher (54%) rate of respiratory diagnoses admissions than during the red tide period. We then divided the diagnoses into subcategories (i.e. pneumonia, bronchitis, asthma, and upper airway disease). When compared with the non-red tide period, the coastal zip codes had increases in the rates of admission of each of the subcategories during the red tide period (i.e. 31, 56, 44, and 64%, respectively). This increase was not observed seen in the inland zip codes. These results suggest that the healthcare community has a significant burden from patients, particularly those who live along the coast, needing emergency medical care for both acute and potentially chronic respiratory illnesses during red tide blooms.

Objective: The objective of this study was to rank U.S. occupations by worker morbidity. Methods: From 1986 through 1994, morbidity information was collected on over 410,000 U.S. workers who participated in the National Health Interview Survey, an annual household survey representative of the U.S. civilian noninstitutionalized population. A multivariate adjusted logistic regression morbidity summary score was created for each worker group based on seven indicators: days of restricted activity, bedrest, and missed work in the previous 2 weeks; doctor visits and hospitalizations in the previous 12 months; reported health conditions; and health status. Results: Worker groups reporting the greatest morbidity included social workers, inspectors, postal clerks, psychologists, and grinding machine operators; worker groups reporting the least morbidity included dentists, pilots, physicians, pharmacists, and dietitians. Conclusions: These findings aid in the identification of worker groups that require increased attention for morbidity research and prevention. [ABSTRACT FROM AUTHOR]

Florida red tides annually occur in the Gulf of Mexico, resulting from blooms of the marine dinoflagellate Karenia brevis. K. brevis produces highly potent natural polyether toxins, known as brevetoxins, that activate voltage-sensitive sodium channels. In experimental animals, brevetoxins cause significant bronchoconstriction. A study of persons who visited the beach recreationally found a significant increase in self-reported respiratory symptoms after exposure to aerosolized Florida red tides. Anecdotal reports indicate that persons with underlying respiratory diseases may be particularly susceptible to adverse health effects from these aerosolized toxins. Fifty-nine persons with physician-diagnosed asthma were evaluated for 1 hr before and after going to the beach on days with and without Florida red tide. Study participants were evaluated with a brief symptom questionnaire, nose and throat swabs, and spirometry approved by the National Institute for Occupational Safety and Health. Environmental monitoring, water and air sampling (i.e., K. brevis, brevetoxins, and particulate size distribution), and personal monitoring (for toxins) were performed. Brevetoxin concentrations were measured by liquid chromatography mass spectrometry, high-performance liquid chromatography, and a newly developed brevetoxin enzyme-linked immunosorbent assay. Participants were significantly more likely to report respiratory symptoms after Florida red tide exposure. Participants demonstrated small but statistically significant decreases in forced expiratory volume in 1 sec, forced expiratory flow between 25 and 75%, and peak expiratory flow after exposure, particularly those regularly using asthma medications. Similar evaluation during nonexposure periods did not significantly differ. This is the first study to show objectively measurable adverse health effects from exposure to aerosolized Florida red tide toxins in persons with asthma. Future studies will examine the possible chronic effects of these toxins among persons with asthma and other chronic respiratory impairment. [ABSTRACT FROM AUTHOR]

Objective: We sought to assess the validity of using current or most recent occupation as surrogate for longest-held job (and its exposures). Methods: The National Health Interview Survey (NHIS) is an annual, probability, cross-sectional U.S. population survey. The 1986 and 1988 NHIS occupational supplements provided information for more than 49,000 workers. Using Cohen's Kappa, concordance was assessed by occupational group and several subgroups. Results: Statistically significant results were observed for all occupational groups. More than 70% of 13 broad occupations had a Kappa of 50.0 or greater, with variable concordance by subpopulation. Among 206 occupational groups, there was more variability: Kappa ranged from 92.7 (dentists) to 9.2 (farm managers). Conclusions: Moderate-to-high levels of agreement was observed in this large, representative sample of US workers. Therefore, current occupation can be used as a surrogate for longest-held job for many occupational subgroups. [ABSTRACT FROM AUTHOR]

RED tide , *DINOFLAGELLATE blooms , *PARALYTIC shellfish poisoning , *GASTROINTESTINAL diseases , *ALGAL blooms - Abstract
Florida red tides are a natural phenomenon caused by dense aggregations of single cell or several species of unicellular organisms. Patches of discolored water, dead or dying fish, and respiratory irritants in the air often characterize these algal blooms. In humans, two distinct clinical entities, depending on the route of exposure, are associated with exposure to the Florida red tide toxins (particularly the brevetoxins). With the ingestion of brevetoxin-contaminated shellfish, neurotoxic shellfish poisoning (NSP) presents as a milder gastroenteritis with neurologic symptoms compared with other marine toxin diseases such as paralytic shellfish poisoning (PSP) or ciguatera fish poisoning. With the inhalation of the aerosolized red tide toxins (especially the brevetoxins) from the sea spray, respiratory irritation and possibly other health effects are reported in both humans and other mammals [Nat. Toxins Drugs (1995) 141; Fleming, L.E., Baden, D.G., 1988. Neurotoxic shellfish poisoning: public health and human health effects.

RED tide , *TOXINS , *WHEEZE - Abstract
During two separate Karenia brevis red tide events, we measured the levels of brevetoxins in air and water samples, conducted personal interviews, and performed pulmonary function tests on people before and after they visited one of two Florida beaches. One hundred and twenty-nine people participated in the study, which we conducted during red tide events in Sarasota and Jacksonville, FL, USA. Exposure was categorized into three levels: low/no exposure, moderate exposure, and high exposure. Lower respiratory symptoms (e.g. wheezing) were reported by 8% of unexposed people, 11% of the moderately exposed people, and 28% of the highly exposed people. We performed nasal–pharyngeal swabs on people who experienced moderate or high exposure, and we found an inflammatory response in over 33% of these participants. We did not find any clinically significant changes in pulmonary function test results; however, the study population was small. In future epidemiologic studies, we plan to further investigate the human health impact of inhaled brevetoxins. [Copyright &y& Elsevier]

The article presents a study of effect of oral contraceptives on the onset of pulmonary lymphangioleiomyomatosis (LAM) disease among women. Pulmonary Lymphangioleiomyomatosis is a rare lung disease of young women that is associated with worsening dyspnea, cough, and recurrent pneumothoraces. The study population was drawn from the University of Miami, School of Medicine, Coral Gables, Florida, LAM patient database. Parameters like demographic factors, smoking history and family history were examined from the survey. None of the participants had a family history of LAM and non of the participants smoked at the time of study. The most commonly reported symptoms of pulmonary illness were allergies, asthma and Chronic Obstructive Pulmonary Disease. Twenty seven percent of the premenopausal women were taking oral contraceptives at the onset of symptoms. There was statistically significant difference in mean age at onset of symptoms between women taking oral contraceptives and women who were not taking oral contraceptives.

CYANOBACTERIA , *TOXINS , *MICROCYSTINS - Abstract
The blue green algae or cyanobacteria represent a diverse group of organisms that produce potent natural toxins. There have been case reports of severe morbidity and mortality in domestic animals through drinking water contaminated by these toxins. Microcystins, in particular, have been associated with acute liver damage and possibly liver cancer in laboratory animals. Although, there has been little epidemiologic research on toxin effects in humans, a study by found an association between primary liver cancer and surface water. Surface water drinking supplies are particularly vulnerable to the growth of these organisms; current US drinking water treatment practices do not monitor or actively treat for blue green algal toxins including the microcystins.After a monitoring survey in Florida found organisms and microcystins (among other cyanobacterial toxins) in surface water drinking sources, a pilot ecological study was performed using a Geographic Information System (GIS) to evaluate the risk of primary hepatocellular carcinoma (HCC) and proximity to a surface water treatment plant at cancer diagnosis. The study linked all HCC cancers diagnosed in Florida from 1981 to 1998 with environmental databases.A significantly increased risk for HCC with residence within the service area of a surface water treatment plant was found compared to persons living in areas contiguous to the surface water treatment plants. However, this increased risk was not seen in comparison to persons living in randomly selected ground water treatment service areas or compared to the Florida cumulative incidence rate for the study period, using various comparison and GIS methodologies. Furthermore, these findings must be interpreted in light of significant issues of latency, high population mobility, and the lack of individual exposure information. Nevertheless, the issue of acute and chronic human health effects associated with the consumption of surface waters possibly contaminated by blue green algal toxins merits further investigation.

In 1992, the American Conference of Governmental Industrial Hygienists (ACGIH®) Chemical Substances Threshold Limit Values (TLVs®) Committee adopted a fivecategory system for classifying the carcinogenicity of industrial chemicals, processes, and agents. At that time, the decision of the TLV Committee was to adopt a system which agreed as closely as possible with the system developed by the International Agency for Research on Cancer (IARC). Recent scientific and international developments, such as attempts at harmonization of occupational exposure guidelines, as well as the passage of time, have caused the TLV Committee to revisit the issue of how best to classify carcinogenicity. The objective of this article is to describe recent changes in classifying carcinogenicity by the TLVCommittee and to examine these changes in relationship to the classification systems used by other groups, particularly the German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area (the MAK Commission). A description is provided of how decisions on carcinogenicity classification are made by the TLV Committee and how the decision process may differ from that of other groups. The changes made since 1992 have been evolutionary in nature, following meetings with the MAK Commission and internal discussions within the committee. Information on mechanism of action will play a greater role in classifying carcinogenicity. [ABSTRACT FROM AUTHOR]

- Abstract
Health care workers are exposed to various infectious agents that can lead to disease transmission during patient care. Emergency first-responders, paramedics, and emergency medical technicians (EMTs) are a subgroup of health care workers particularly at risk for occupational exposure to bloodborne pathogens. The Centers for Disease Control and Prevention has recommended universal precautions to prevent occupational transmission of bloodborne pathogens among health care workers. This cross-sectional study evaluates risks and behaviors for occupational exposure to bloodborne pathogens among urban paramedics and EMTs in Dade County, Florida. Reported exposure via multiple routes was common, especially among paramedics. Knowledge of universal precautions was high, but reported practices were suboptimal because of inadequate information, as well as logistical and access issues. Additional research, administrative effort, and regulation are needed to increase the application of universal precautions in the prehospital setting. [ABSTRACT FROM AUTHOR]

Research has indicated that the appropriate intake of folic acid, a B vitamin, before and during early pregnancy has been shown to prevent 50–70% of neural-tube defects. Increased NTD incidence has long been reported to occur more frequently among women of lower socioeconomic (SES). Since consumption of the folate-rich Mediterranean diet in Spain does not vary by socio-economic status (SES), we hypothesized that there would be no social class effect on NTD occurrence. Using data from a Spanish hospital-based birth defects registry, we studied the risk of Neural Tube Defects (NTDs) in 980 cases and 774 controls between 1980 and 2003. Our analysis showed that the risk of NTDs did not vary by SES. This finding suggests that increased access to folate and nutrition education might benefit women of lower SES in the US.

Florida red tide is caused by Karenia brevis, a dinoflagellate that periodically blooms, releasing its potent neurotoxin, brevetoxin, into the surrounding waters and air along the coast of the Gulf of Mexico. Exposure to Florida red tide toxins has been associated with adverse human health effects and massive fish and marine mammal deaths. The articles in this mini-monograph describe the ongoing interdisciplinary and interagency research program that characterizes the exposures and health effects of aerosolized Florida red tide toxins (brevetoxins). The interdisciplinary research program uses animal models and laboratory studies to develop hypotheses and apply these findings to in situ human exposures. Our ultimate goal is to develop appropriate prevention measures and medical interventions to mitigate or prevent adverse health effects from exposure to complex mixtures of aerosolized red tide toxins.

Natural environments can be used to promote health through facilitating recreational walking. However, efforts to encourage this often neglect messages identified in psychological research that are effective at influencing intentions to walk. This is despite the National Institute for Health and Care Excellence stating that promotional efforts should utilize theoretical frameworks of behaviour change and be targeted towards less active adults. As an illustrative example, this experiment compared a prototypical recreational walking brochure with an "enhanced" version including such persuasive messages on people's intentions to walk for recreation in natural environments. The enhanced brochure heightened intentions for inexperienced recreational walkers through our hypothesized mechanisms, but appeared to dissuade already-experienced walkers. Optimal messaging strategies in recreational walking brochures require tailoring to more and less active readerships. Guidelines are provided for authors of recreational walking brochures, though the principles and techniques could easily be extended to other means of outdoor walking promotion.

Building on evidence of the links between bluespace and public health, this study explores the governance of bluespace infrastructure to promote human health and well-being in Plymouth (UK). Using in-depth retrospective interviews and document analysis, this study focused on the role of governance in urban planning and development, specifically, the implementation phase of a bluespace infrastructure intervention. A deductive qualitative approach categorised content into themes related to pre-established water governance frameworks. Key findings from this study emphasise: the importance of health and welfare concerns around blue spaces as an incentive to getting started; collaborative stakeholder participation and engagement; the necessity of adequate funding; and the importance of continued monitoring and maintenance of urban blue space infrastructure. Based on reflective accounts of stakeholder experiences, the successes of the implementation process of the redevelopment are highlighted. More successful and sustainable bluespace interventions can be realised through ongoing considerations of effective water governance. [ABSTRACT FROM AUTHOR]

Disentangling the impact of the weather on transmission of infectious diseases is crucial for health protection, preparedness and prevention. Because weather factors are co-incidental and partly correlated, we have used geography to separate out the impact of individual weather parameters on other seasonal variables using campylobacteriosis as a case study. Campylobacter infections are found worldwide and are the most common bacterial food-borne disease in developed countries, where they exhibit consistent but country specific seasonality. We developed a novel conditional incidence method, based on classical stratification, exploiting the long term, high-resolution, linkage of approximately one-million campylobacteriosis cases over 20 years in England and Wales with local meteorological datasets from diagnostic laboratory locations. The predicted incidence of campylobacteriosis increased by 1 case per million people for every 5° (Celsius) increase in temperature within the range of 8°–15°. Limited association was observed outside that range. There were strong associations with day-length. Cases tended to increase with relative humidity in the region of 75–80%, while the associations with rainfall and wind-speed were weaker. The approach is able to examine multiple factors and model how complex trends arise, e.g. the consistent steep increase in campylobacteriosis in England and Wales in May-June and its spatial variability. This transparent and straightforward approach leads to accurate predictions without relying on regression models and/or postulating specific parameterisations. A key output of the analysis is a thoroughly phenomenological description of the incidence of the disease conditional on specific local weather factors. The study can be crucially important to infer the elusive mechanism of transmission of campylobacteriosis; for instance, by simulating the conditional incidence for a postulated mechanism and compare it with the phenomenological patterns as benchmark. The findings challenge the assumption, commonly made in statistical models, that the transformed mean rate of infection for diseases like campylobacteriosis is a mere additive and combination of the environmental variables. Author summary: There is good evidence that weather influences some infectious diseases, driving the seasonal and geographic distribution. This is relevant to gastrointestinal infections, which cause high morbidity and mortality worldwide. Weather can impact people's behaviour, pathogen survival and distribution, animal husbandry, and other environmental variables. We used campylobacteriosis in England and Wales as a case-study to examine a new methodology because it has a distinctive seasonality. The approach compares daily data on affected people by laboratory, the population of the laboratory catchments, and local weather variables. This allows Campylobacter incidence to be compared across the values of these variables (e.g. low to high temperature) to provide an estimate of how individual weather variables, alone or in combination, affect disease incidence. We call this the Comparative Conditional Incidence. The results from this analysis are used to build a mathematical model that represents how weather through the year influences the seasonality of disease. The factors most associated with Campylobacter are day-length, air temperature and relative humidity. This will influence future research to understand why the environment influences disease occurrence, and what the burden and pattern of the disease under different climatic scenarios. The methods may have relevance to other seasonal diseases. [ABSTRACT FROM AUTHOR]

Increasingly, the potential short and long-term impacts of climate change on human health and wellbeing are being demonstrated. However, other environmental change factors, particularly relating to the natural environment, need to be taken into account to understand the totality of these interactions and impacts. This paper provides an overview of ongoing research in the Health Protection Research Unit (HPRU) on Environmental Change and Health, particularly around the positive and negative effects of the natural environment on human health and well-being and primarily within a UK context. In addition to exploring the potential increasing risks to human health from water-borne and vector-borne diseases and from exposure to aeroallergens such as pollen, this paper also demonstrates the potential opportunities and co-benefits to human physical and mental health from interacting with the natural environment. The involvement of a Health and Environment Public Engagement (HEPE) group as a public forum of “critical friends” has proven useful for prioritising and exploring some of this research; such public involvement is essential to minimise public health risks and maximise the benefits which are identified from this research into environmental change and human health. Research gaps are identified and recommendations made for future research into the risks, benefits and potential opportunities of climate and other environmental change on human and planetary health.

Innovative actions are local initiatives which leverage the interactions between the ocean and human health to reduce the risks and enhance the benefits for the stakeholders and the natural environment. These initiatives can have strong positive effects on human health and wellbeing as well as on the marine environment. We analysed 150 such innovative actions in Europe. Using a combined case study and survey approach, innovative actions were identified using interviews and content analysis of websites and compiled into a database. Quantitative data were analysed according to the Drivers, Pressures, State, Impact and Response (DPSIR) framework, guided by selected in-depth interviews. Overall, the innovative actions provided a positive impact on the health of both the ocean and humans through increasing food provision, water quality and tourism opportunities; and addressing environmental issues such as commercial fish stock depletion, pollution and climate change. Innovative actions contributed to meeting various targets of the Sustainable Development Goals (SDGs) 3, 13 and 14. These actions played a potential role ahead of and alongside policy. Some of the innovative actions may have potential to be put in place elsewhere. Such up-scaling would need to be adapted to local circumstances and could be facilitated by an innovative action exchange platform. [ABSTRACT FROM AUTHOR]

Background: Healthcare professionals throughout the developed world report higher levels of sickness absence, dissatisfaction, distress, and “burnout” at work than staff in other sectors. There is a growing call for the ‘triple aim’ of healthcare delivery (improving patient experience and outcomes and reducing costs; to include a fourth aim: improving healthcare staff experience of healthcare delivery. A systematic review commissioned by the United Kingdom’s (UK) Department of Health reviewed a large number of international healthy workplace interventions and recommended five whole-system changes to improve healthcare staff health and wellbeing: identification and response to local need, engagement of staff at all levels, and the involvement, visible leadership from, and up-skilling of, management and board-level staff. Objectives: This systematic review aims to identify whole-system healthy workplace interventions in healthcare settings that incorporate (combinations of) these recommendations and determine whether they improve staff health and wellbeing. Methods: A comprehensive and systematic search of medical, education, exercise science, and social science databases was undertaken. Studies were included if they reported the results of interventions that included all healthcare staff within a healthcare setting (e.g. whole hospital; whole unit, e.g. ward) in collective activities to improve physical or mental health or promote healthy behaviours. Results: Eleven studies were identified which incorporated at least one of the whole-system recommendations. Interventions that incorporated recommendations to address local need and engage the whole workforce fell in to four broad types: 1) pre-determined (one-size-fits-all) and no choice of activities (two studies); or 2) pre-determined and some choice of activities (one study); 3) A wide choice of a range of activities and some adaptation to local needs (five studies); or, 3) a participatory approach to creating programmes responsive and adaptive to local staff needs that have extensive choice of activities to participate in (three studies). Only five of the interventions included substantial involvement and engagement of leadership and efforts aimed at up-skilling the leadership of staff to support staff health and wellbeing. Incorporation of more of the recommendations did not appear to be related to effectiveness. The heterogeneity of study designs, populations and outcomes excluded a meta-analysis. All studies were deemed by their authors to be at least partly effective. Two studies reported statistically significant improvement in objectively measured physical health (BMI) and eight in subjective mental health. Six studies reported statistically significant positive changes in subjectively assessed health behaviours. Conclusions: This systematic review identified 11 studies which incorporate at least one of the Boorman recommendations and provides evidence that whole-system healthy workplace interventions can improve health and wellbeing and promote healthier behaviours in healthcare staff.

Infectious diseases attributable to unsafe water supply, sanitation and hygiene (e.g. Cholera, Leptospirosis, Giardiasis) remain an important cause of morbidity and mortality, especially in low-income countries. Climate and weather factors are known to affect the transmission and distribution of infectious diseases and statistical and mathematical modelling are continuously developing to investigate the impact of weather and climate on water-associated diseases. There have been little critical analyses of the methodological approaches. Our objective is to review and summarize statistical and modelling methods used to investigate the effects of weather and climate on infectious diseases associated with water, in order to identify limitations and knowledge gaps in developing of new methods. We conducted a systematic review of English-language papers published from 2000 to 2015. Search terms included concepts related to water-associated diseases, weather and climate, statistical, epidemiological and modelling methods. We found 102 full text papers that met our criteria and were included in the analysis. The most commonly used methods were grouped in two clusters: process-based models (PBM) and time series and spatial epidemiology (TS-SE). In general, PBM methods were employed when the bio-physical mechanism of the pathogen under study was relatively well known (e.g. Vibrio cholerae); TS-SE tended to be used when the specific environmental mechanisms were unclear (e.g. Campylobacter). Important data and methodological challenges emerged, with implications for surveillance and control of water-associated infections. The most common limitations comprised: non-inclusion of key factors (e.g. biological mechanism, demographic heterogeneity, human behavior), reporting bias, poor data quality, and collinearity in exposures. Furthermore, the methods often did not distinguish among the multiple sources of time-lags (e.g. patient physiology, reporting bias, healthcare access) between environmental drivers/exposures and disease detection. Key areas of future research include: disentangling the complex effects of weather/climate on each exposure-health outcome pathway (e.g. person-to-person vs environment-to-person), and linking weather data to individual cases longitudinally.

The effects of 'nature' on mental health and subjective well-being have yet to be consistently integrated into ecosystem service models and frameworks. To address this gap, we used data on subjective mental well-being from an 18-country survey to test a conceptual model integrating mental health with ecosystem services, initially proposed by Bratman et al. We analysed a range of individual and contextual factors in the context of 14,998 recreational visits to blue spaces, outdoor environments which prominently feature water. Consistent with the conceptual model, subjective mental well-being outcomes were dependent upon on a complex interplay of environmental type and quality, visit characteristics, and individual factors. These results have implications for public health and environmental management, as they may help identify the bluespace locations, environmental features, and key activities, that are most likely to impact well-being, but also potentially affect recreational demand on fragile aquatic ecosystems.

Whilst green space has been linked to healthier sleep outcomes, the roles of specific types of nature exposure, potential underlying mechanisms, and between-country variations in nature-sleep associations have received little attention. Drawing on cross-sectional survey data from an 18-country sample of adults (N = 16,077) the current study examined: 1) the relative associations between six different types of nature exposure (streetscape greenery, blue view from home, green space within 1 km, coast within 1 km, green space visits, blue space visits) and insufficient sleep (<6 h vs. 7–10 h per day); 2) whether these relationships were mediated by better mental wellbeing and/or physical activity; and 3) the consistency of these pathways among the different countries. After controlling for covariates, neighbourhood nature measures (green space, coast within 1 km) were not significantly associated with insufficient sleep; but nature visible from home (streetscape greenery, blue views) and recreational visits to green and blue spaces were each associated with less insufficient sleep. Significant nature-sleep associations were mediated, to varying degrees, by better mental wellbeing, but not self-reported physical activity. Country-level heterogeneity in the strength of nature-sleep associations was observed. Increasing nature visible from the home may represent a promising strategy for promoting healthier sleep duration at the population level, whilst nature-based interventions encouraging individuals to spend time in local green/blue spaces may be an appropriate target to assist individuals affected by insufficient sleep. • Examined the links between six types of nature exposure and insufficient sleep. • Neighbourhood nature measures did not significantly predict insufficient sleep. • Nature visible from home and nature visits associated with lower insufficient sleep. • Significant nature-sleep associations were mediated by better mental wellbeing. • Country-level heterogeneity in nature-sleep associations was observed.

PHYSICAL activity , *NON-communicable diseases , *ECONOMIC aspects of diseases , *MENTAL depression , *ISCHEMIC stroke - Abstract
• In 2019, 22 million adults in England visited natural environments at least weekly. • Physical activity on these visits prevented 12,763 cases of non-communicable disease. • Annual societal costs of the disease avoided were estimated at £108.7 million. • Strategies increasing visitor activity or volume may prevent more cases of disease. Physical activity (PA) reduces the risk of several non-communicable diseases (NCDs). Natural environments support recreational PA. Using data including a representative cross-sectional survey of the English population, we estimated the annual value of nature-based PA conducted in England in 2019 in terms of avoided healthcare and societal costs of disease. Population-representative data from the Monitor of Engagement with the Natural Environment (MENE) survey (n = 47,580; representing 44,386,756) were used to estimate the weekly volume of nature-based recreational PA by adults in England in 2019. We used epidemiological dose–response data to calculate incident cases of six NCDs (ischaemic heart disease (IHD), ischaemic stroke (IS), type 2 diabetes (T2D), colon cancer (CC), breast cancer (BC) and major depressive disorder (MDD)) prevented through nature-based PA, and estimated associated savings using published costs of healthcare, informal care and productivity losses. We investigated additional savings resulting from hypothetical increases in: (a) visitor PA and (b) visitor numbers. In 2019, 22 million adults > 16 years of age in England visited natural environments at least weekly. At reported volumes of nature-based PA, we estimated that 550 cases of IHD, 168 cases of IS, 1,410 cases of T2D, 41 cases of CC, 37 cases of BC and 10,552 cases of MDD were prevented, creating annual savings of £108.7million (95 % uncertainty interval: £70.3million; £150.3million). Nature-based recreational PA in England results in reduced burden of disease and considerable annual savings through prevention of priority NCDs. Strategies that increase nature-based PA could lead to further reductions in the societal burden of NCDs. [ABSTRACT FROM AUTHOR]

Background: Single-use personal protective equipment (PPE) has been essential to protect healthcare workers during the COVID-19 pandemic. However, intensified use of PPE could counteract the previous efforts made by the UK NHS Trusts to reduce their plastic footprint. Design and methods: In this study, we conducted an in-depth case study in the Royal Cornwall Hospitals NHS Trust to investigate plastic-related issues in a typical NHS Trust before, during and after the pandemic. We first collected hospital routine data on both procurement and usage of single-use PPE (including face masks, aprons, and gowns) for the time period between April 2019 and August 2020. We then interviewed 12 hospital staff across a wide remit, from senior managers to consultants, nurses and catering staff, to gather qualitative evidence on the overall impact of COVID-19 on the Trust regarding plastic use. Results:We found that although COVID-19 had increased the procurement and the use of single-use plastic substantially during the pandemic, it did not appear to have changed the focus of the hospital on implementing measures to reduce single-use plastic in the long term. We then discussed the barriers and opportunities to tackle plastic issues within the NHS in the post-COVID world, for example, a circular healthcare model. Conclusion: Investment is needed in technologies and processes that can recycle and reuse a wider range of single-use plastics, and innovate sustainable alternatives to replace singleuse consumables used in the NHS to construct a fully operational closed material loop healthcare system.

CLIMATE change , *CHRONIC diseases , *PUBLIC health , *MENTAL health - Abstract
As climate change alters environmental conditions, the incidence and global patterns of human diseases are changing. These modifications to disease profiles and the effects upon human pharmaceutical usage are discussed. Climate-related environmental changes are associated with a rise in the incidence of chronic diseases already prevalent in the Northern Hemisphere, for example, cardiovascular disease and mental illness, leading to greater use of associated heavily used Western medications. Sufferers of respiratory diseases may exhibit exacerbated symptoms due to altered environmental conditions (e.g., pollen). Respiratory, water-borne, and food-borne toxicants and infections, including those that are vector borne, may become more common in Western countries, central and eastern Asia, and across North America. As new disease threats emerge, substantially higher pharmaceutical use appears inevitable, especially of pharmaceuticals not commonly employed at present (e.g., antiprotozoals). The use of medications for the treatment of general symptoms (e.g., analgesics) will also rise. These developments need to be viewed in the context of other major environmental changes (e.g., industrial chemical pollution, biodiversity loss, reduced water and food security) as well as marked shifts in human demographics, including aging of the population. To identify, prevent, mitigate, and adapt to potential threats, one needs to be aware of the major factors underlying changes in the use of pharmaceuticals and their subsequent release, deliberately or unintentionally, into the environment. This review explores the likely consequences of climate change upon the use of medical pharmaceuticals in the Northern Hemisphere.© Clare H. Redshaw, Will M. Stahl-Timmins, Lora E.

Increasing greenhouse gas emissions threaten human health and the environment. In response, healthcare managers face significant challenges in balancing operational decisions about patient care with carbon mitigation targets. We explore a bottom-up modeling framework to aid in the decision-making for both carbon and cost in healthcare, using data from a case study in Cornwall, UK. A model was built and run for secondary healthcare, specifically outpatient clinics, theater lists, beds, and diagnostic facilities. Five scenarios were tested: business-as-usual; service expansion; site closure; water temperature reduction; and theater optimization. The estimated emissions from secondary healthcare in Cornwall ran to 5787 T CO2 eq with patient travel adding 2215 T CO2eq. Closing selected sites would have reduced this by 4% (261 T CO2 eq) , a reduction less than the resulting increases in patient transport emissions. Reducing hot water temperatures by 5 °C and improving theater usage would lower the footprint by 0.7% (44 T CO2 eq ) and 0.08% (5 T CO2 eq ) , respectively. We consider bottom-up models important tools in the process of estimating and modeling the carbon footprint of healthcare. For the carbon reduction targets of the healthcare sector to be met, the use of these bottom-up models in decision making and forward planning is pivotal. [ABSTRACT FROM AUTHOR]

Objectives. The working poor sometimes delay retirement to survive. However, their higher risk of disease and disability threatens both their financial survival and their ability to work through the retirement years. We used the burden of disease attributable to arthritis by occupational class to illustrate the challenges faced by the older poor. Methods. We merged data from the National Health Interview Survey, Medical Expenditure Panel Survey, and the National Death Index into a single database. We then calculated and compared age- and occupational class-specific quality-adjusted life years (QALYs) between workers with and without arthritis by using unabridged life tables. Results. White-collar workers have a higher overall health-related quality of life than do other workers, and suffer fewer QALYs lost to arthritis at all ages. For instance, whereas 65-year-old white-collar workers without arthritis look forward to 17 QALYs of future life, blue-collar workers with arthritis experience only 11, and are much less likely to remain in the workforce than are those in service, farming, or white-collar jobs. Conclusions. To meet the needs of the aging workforce, more extensive health and disability insurance will be needed. [ABSTRACT FROM AUTHOR]

Abstract: To enhance information sharing and garner increased support from the public for scientific research, funding agencies now typically require that research groups receiving support convey their work to stakeholders. The National Institute of Environmental Health Sciences (NIEHS) funded Aerosolized Florida Red Tide P01 research group (Florida Red Tide Research Group) has employed a variety of outreach strategies to meet this requirement. Messages developed from this project began a decade ago and have evolved from basic print material (fliers and posters) to an interactive website, to the use of video and social networking technologies, such as Facebook and Twitter. The group was able to track dissemination of these information products; however, evaluation of their effectiveness presented much larger challenges. The primary lesson learned by the Florida Red Tide Research Group is that the best ways to reach specific stakeholders are to develop unique products or services to address specific stakeholders’ needs, such as the Beach Conditions Reporting System. Based on the experience of the Group, the most productive messaging products result when scientific community engages potential stakeholders and outreach experts during the very initial phases of a project.

SMOKELESS tobacco , *TOBACCO , *EMPLOYEES , *HEALTH surveys , *PANCREATIC cancer - Abstract
The primary aim was to examine whether increasing workplace smoking restrictions have led to an increase in smokeless tobacco use among US workers. Smokeless tobacco exposure increases the risk of oral cavity, esophageal, and pancreatic cancers, and stroke. The prevalence of smokeless tobacco use decreased from 1987-2000, except among men 25-44. While smokeless tobacco use has declined in the general population, it may be that the prevalence of smokeless tobacco use has increased among workers due to workplace smoking restrictions, which have been shown to have increased over the years. Using the most current nationally representative National Health Interview Survey (NHIS) data, we examined whether increasing workplace smoking restrictions have led to an increase in smokeless tobacco use among US workers (n = 125,838). There were no significant changes in smokeless tobacco use prevalence from 1987-2005 (pooled prevalence = 3.53%); rates also were lower in smoke free workplaces. Worker groups with high rates of smokeless tobacco use included farm workers (10.51%) and blue collar workers (7.26%). Results indicate that smokeless tobacco prevention strategies targeting particular worker groups are warranted. [ABSTRACT FROM AUTHOR]
