There is some evidence that neighborhood deprivation increases residents' risk of foodborne illnesses. Because urban areas with the least available access to adequate amounts of nutritious or affordable food options (or "food deserts") also tend to be the most deprived areas within a city, it is hypothesized that food access and foodborne illness risk are linked. However, the complexity of tracking numbers and sources of gastrointestinal (GI) illnesses often leads researchers to speculate about reasons for disproportionate rates of pathogen outbreaks among demographic groups. This study explores the suitability of existing data to examine associations between food deserts and the spatial distribution of GI illnesses in Hamilton, Ontario, Canada. A spatial analysis by using GIS software methodology was used to identify and map food retail outlets and accessibility, as well as GI illness outbreaks and sales of antidiarrhea, antinausea, and rehydration products (used as a proxy for GI cases) within the city, based on available data. Statistical analysis of the maps shows no statistical relationship between location, access to food outlets, and rates of GI illness. The analysis points to shortfalls and gaps in the existing data, which leaves us unable to draw conclusions either supporting or refuting our hypothesis. This article includes recommendations to improve the current system of illness reporting and to continue to refine the definition and process of mapping food access issues. A more comprehensive set of data would enable municipalities to more easily identify groups most at risk, depending on exposures and the type of pathogen, and reduce the occurrence of foodborne disease.

This study estimated the annual socioeconomic costs of food-borne disease in 2008 from a societal perspective and using a cost-of-illness method. Our model employed a comprehensive set of diagnostic disease codes to define food-borne diseases with using the Korea National Health Insurance (KNHI) reimbursement data. This study classified the food borne illness as three types of symptoms according to the severity of the illness: mild, moderate, severe. In addition to the traditional method of assessing the cost-of-illness, the study included measures to account for the lost quality of life. We estimated the cost of the lost quality of life using quality-adjusted life years and a visual analog scale. The direct cost included medical and medication costs, and the non-medical costs included transportation costs, caregiver's cost and administration costs. The lost productivity costs included lost workdays due to illness and lost earnings due to premature death. The study found the estimated annual socioeconomic costs of food-borne disease in 2008 were 954.9 billion won (735.3 billion won-996.9 billion won). The medical cost was 73.4 - 76.8% of the cost, the lost productivity cost was 22.6% and the cost of the lost quality of life was 26.0%. Most of the cost-of-illness studies are known to have underestimated the actual socioeconomic costs of the subjects, and these studies excluded many important social costs, such as the value of pain, suffering and functional disability. The study addressed the uncertainty related to estimating the socioeconomic costs of food-borne disease as well as the updated cost estimates. Our estimates could contribute to develop and evaluate policies for food-borne disease.

Data from the recalls of meat and poultry products from 2000 through 2012 due to Salmonella contamination were used to assess the factors associated with the recovery of the recalled product and to develop quantitative models to estimate the number of illnesses prevented by recalls. The percentage of product recovered following a recall action was not dependent on establishment size, recall expansions, complexity of the distribution chain, type of distribution, amount of time between the production and recall dates, or number of pounds of product recalled. However, illness-related recalls were associated with larger amounts of recalled product, smaller percentages of recalled product recovered, a greater number of days between the production date and recall date, and nationwide distribution than were recalls that were not illness related. In addition, the detection of recall-associated illnesses appeared to be enhanced in states with strong foodborne illness investigation systems. The number of Salmonella illnesses prevented by recalls was based on the number of illnesses occurring relative to the number of pounds consumed, which was then extrapolated to the number of pounds of recalled product recovered. A simulation using a program evaluation and review technique probability distribution with illness-related recalls from 2003 through 2012 estimated that there were 19,000 prevented Salmonella illnesses, after adjusting for underdiagnosis. Recalls not associated with illnesses from 2000 through 2012 prevented an estimated additional 8,300 Salmonella illnesses, after adjusting for underdiagnosis. Although further improvements to ensure accurate and complete reporting should be undertaken, our study demonstrates that recalls are an important tool for preventing additional Salmonella illnesses. Moreover, additional training resources dedicated to public health agencies for enhancing foodborne illness detection, investigations, and rapid response and reporting would

Full Text Available Foodborne illness is a serious and preventable public health problem affecting 1 in 6 Americans with cost estimates over $50 billion annually. Local health departments license and inspect restaurants to ensure food safety and respond to reports of suspected foodborne illness. The City of St. Louis Department of Health adopted the HealthMap Foodborne Dashboard (Dashboard, a tool that monitors Twitter for tweets about food poisoning in a geographic area and allows the health department to respond. We evaluated the implementation by interviewing employees of the City of St. Louis Department of Health involved in food safety. We interviewed epidemiologists, environmental health specialists, health services specialists, food inspectors, and public information officers. Participants viewed engaging innovation participants and executing the innovation as challenges while they felt the Dashboard had relative advantage over existing reporting methods and was not complex once in place. This study is the first to examine practitioner perceptions of the implementation of a new technology in a local health department. Similar implementation projects should focus more on process by developing clear and comprehensive plans to educate and involve stakeholders prior to implementation.

While investigating an outbreak of gastrointestinal disease associated with a restaurant, the New York City Department of Health and Mental Hygiene (DOHMH) noted that patrons had reported illnesses on the business review website Yelp (http://www.yelp.com) that had not been reported to DOHMH. To explore the potential of using Yelp to identify unreported outbreaks, DOHMH worked with Columbia University and Yelp on a pilot project to prospectively identify restaurant reviews on Yelp that referred to foodborne illness. During July 1, 2012-March 31, 2013, approximately 294,000 Yelp restaurant reviews were analyzed by a software program developed for the project. The program identified 893 reviews that required further evaluation by a foodborne disease epidemiologist. Of the 893 reviews, 499 (56%) described an event consistent with foodborne illness (e.g., patrons reported diarrhea or vomiting after their meal), and 468 of those described an illness within 4 weeks of the review or did not provide a period. Only 3% of the illnesses referred to in the 468 reviews had also been reported directly to DOHMH via telephone and online systems during the same period. Closer examination determined that 129 of the 468 reviews required further investigation, resulting in telephone interviews with 27 reviewers. From those 27 interviews, three previously unreported restaurant-related outbreaks linked to 16 illnesses met DOHMH outbreak investigation criteria; environmental investigation of the three restaurants identified multiple food-handling violations. The results suggest that online restaurant reviews might help to identify unreported outbreaks of foodborne illness and restaurants with deficiencies in food handling. However, investigating reports of illness in this manner might require considerable time and resources.

Although contamination of food can occur at any point from farm to table, restaurant food workers are a common source of foodborne illness. We describe the characteristics of restaurant-associated foodborne disease outbreaks and explore the role of food workers by analysing outbreaks associated with restaurants from 1998 to 2013 reported to the Centers for Disease Control and Prevention's Foodborne Disease Outbreak Surveillance System. We identified 9788 restaurant-associated outbreaks. The median annual number of outbreaks was 620 (interquartile range 618-629). In 3072 outbreaks with a single confirmed aetiology reported, norovirus caused the largest number of outbreaks (1425, 46%). Of outbreaks with a single food reported and a confirmed aetiology, fish (254 outbreaks, 34%) was most commonly implicated, and these outbreaks were commonly caused by scombroid toxin (219 outbreaks, 86% of fish outbreaks). Most outbreaks (79%) occurred at sit-down establishments. The most commonly reported contributing factors were those related to food handling and preparation practices in the restaurant (2955 outbreaks, 61%). Food workers contributed to 2415 (25%) outbreaks. Knowledge of the foods, aetiologies, and contributing factors that result in foodborne disease restaurant outbreaks can help guide efforts to prevent foodborne illness.

Food contamination by pathogenic microorganisms has been a serious public health problem and a cause of huge economic losses worldwide. Foodborne pathogenic Escherichia coli (E. coli) contamination, such as that with E. coli O157 and O104, is very common, even in developed countries. Bacterial contamination may occur during any of the steps in the farm-to-table continuum from environmental, animal, or human sources and cause foodborne illness. To understand the causes of the foodborne outbreaks by E. coli and food-contamination prevention measures, we collected and investigated the past 10 years' worldwide reports of foodborne E. coli contamination cases. In the first half of this review article, we introduce the infection and symptoms of five major foodborne diarrheagenic E. coli pathotypes: enteropathogenic E. coli (EPEC), Shiga toxin-producing E. coli/enterohemorrhagic E. coli (STEC/EHEC), Shigella/enteroinvasive E. coli (EIEC), enteroaggregative E. coli (EAEC), and enterotoxigenic E. coli (ETEC). In the second half of this review article, we introduce the foodborne outbreak cases caused by E. coli in natural foods and food products. Finally, we discuss current developments that can be applied to control and prevent bacterial food contamination.

to assess changes in the food commodities associated most frequently with outbreaks that might occur following improvements in food safety or changes in consumption patterns or food preparation practices. Prevention of foodborne disease depends on targeted interventions at appropriate points from food production to food preparation. Efforts to reduce foodborne illness should focus on the pathogens and food commodities causing the most outbreaks and outbreak-associated illnesses, including beef, poultry, fish, and produce.

Foodborne illness incidence rates and food safety risks for populations of low socioeconomic status and minority race/ethnicity: a review of the literature.

Science.gov (United States)

Quinlan, Jennifer J

2013-08-15

While foodborne illness is not traditionally tracked by race, ethnicity or income, analyses of reported cases have found increased rates of some foodborne illnesses among minority racial/ethnic populations. In some cases (Listeria, Yersinia) increased rates are due to unique food consumption patterns, in other cases (Salmonella, Shigella, Campylobacter) it is unclear why this health disparity exists. Research on safe food handling knowledge and behaviors among low income and minority consumers suggest that there may be a need to target safe food handling messages to these vulnerable populations. Another possibility is that these populations are receiving food that is less safe at the level of the retail outlet or foodservice facility. Research examining the quality and safety of food available at small markets in the food desert environment indicates that small corner markets face unique challenges which may affect the quality and potential safety of perishable food. Finally, a growing body of research has found that independent ethnic foodservice facilities may present increased risks for foodborne illness. This review of the literature will examine the current state of what is known about foodborne illness among, and food safety risks for, minority and low socioeconomic populations, with an emphasis on the United States and Europe.

Food-borne pathogens, health and role of dietary phytochemicals.

Science.gov (United States)

Shetty, K; Labbe, R G

1998-12-01

Infectious diseases transmitted by food have become a major public health concern in recent years. In the USA alone, there are an estimated 6-33 million cases each year. The list of responsible agents continues to grow. In the past 20 years some dozen new pathogens that are primarily food-borne have been identified. Fruits and vegetables, often from the global food market, have been added to the traditional vehicles of food-borne illness; that is, undercooked meat, poultry, seafood, or unpasteurized milk. Such products are minimally processed and have fewer barriers to microbial growth such as salt, sugar or preservatives. The evolution of the epidemiology of food-borne illness requires a rethinking of traditional, though still valid, solutions for their prevention. Among various strategies to prevent food-borne pathogens, use of dietary phytochemicals is promising. The major obstacle in the use of dietary phytochemical is the consistency of phytochemicals in different foods due to their natural genetic variation. We have developed a novel tissue-culture-based selection strategy to isolate elite phenolic phytochemical-producing clonal lines of species belonging to the family Lamiaceae. Among several species we have targeted elite clonal lines of thyme (Thymus vulgaris) and oregano (Origanum vulgare) against Escherichia coli and Clostridium perfrigens in fresh and processed meats. We are also evaluating high phenolic profile-containing clonal lines of basil (Ocimum basilicum) to inhibit gastric ulcer-causing Helicobacter pylori. Other elite lines of the members of the family Lamiaceae, rosemary (Rosmarinus officinalis) and salvia (Salvia officinalis) also hold promise against a wide range of food pathogens such as Salmonella species in poultry products and Vibrio species in seafood.

Foodborne illnesses caused by microbial and chemical contaminants in food are a substantial health burden worldwide. In 2007, human vibriosis (non-cholera Vibrio infections) became a notifiable disease in the United States. In addition, Vibrio species are among the 31 major known pathogens transmitted through food in the United States. Diverse surveillance systems for foodborne pathogens also track outbreaks, illnesses, hospitalization and deaths due to non-cholera vibrios. Considering the recognition of vibriosis as a notifiable disease in the United States and the availability of diverse surveillance systems, there is a need for the development of easily deployed visualization and analysis approaches that can combine diverse data sources in an interactive manner. Current efforts to address this need are still limited. Visual analytics is an iterative process conducted via visual interfaces that involves collecting information, data preprocessing, knowledge representation, interaction, and decision making. We have utilized public domain outbreak and surveillance data sources covering 1973 to 2010, as well as visual analytics software to demonstrate integrated and interactive visualizations of data on foodborne outbreaks and surveillance of Vibrio species. Through the data visualization, we were able to identify unique patterns and/or novel relationships within and across datasets regarding (i) causative agent; (ii) foodborne outbreaks and illness per state; (iii) location of infection; (iv) vehicle (food) of infection; (v) anatomical site of isolation of Vibrio species; (vi) patients and complications of vibriosis; (vii) incidence of laboratory-confirmed vibriosis and V. parahaemolyticus outbreaks. The additional use of emerging visual analytics approaches for interaction with data on vibriosis, including non-foodborne related disease, can guide disease control and prevention as well as ongoing outbreak investigations.

Although many public health articles have been published detailing foodborne illness outbreaks, a medical literature search revealed no articles that detail a case study or a specific response of a deployed U.S. military unit to a potential foodborne illness. This article describes a recent public health case study of a U.S. Special Operations Forces (SOF) team sickened while deployed to South America. It highlights public health factors which may affect U.S. personnel deployed or serving overseas and may serve as a guide for a deployed SOF medic to reference in response to a potential food- or waterborne illness outbreak. Eight food samples and five water samples were collected. The food samples were obtained from the host nation kitchen that provided food to the SOF team. The water samples were collected from the kitchen as well as from multiple sites on the host nation base. These samples were packaged in sterile containers, stored at appropriate temperatures, and submitted to a U.S. Army diagnostic laboratory for analysis. Laboratory results confirmed the presence of elevated aerobic plate counts (APCs) in the food prepared by the host nation and consumed by the SOF team. High APCs in food are the primary indicator of improper sanitation of food preparation surfaces and utensils. This case study concluded that poor kitchen sanitation, improper food storage, preparation, and/or holding were the probable conditions that led to the team?s symptoms. These results emphasize the importance of ensuring safe food and water for U.S. personnel serving overseas, especially in a deployment or combat setting. Contaminated food and/or water will negatively impact the health and availability of forces, which may lead to mission failure. The SOF medic must respond to potential outbreaks and be able to (1) critically inspect food preparation areas and accurately advise commanders in order to correct deficiencies and (2) perform food/water surveillance testing consistently

Foodborne disease is a major public health problem. The present study examined Annona squamosa leaves, which are traditionally used to treat diarrhea and other infections, for their potential to be used in modern food safety or medicine. Active constituents were partially purified by ethanol extraction and column chromatography. MICs of the extract were 62.5 to 125 microg/mL against Bacillus cereus, Listeria monocytogenes and Staphylococcus aureus, and 250 microg/mL against Campylobacter jejuni. In time-kill assays, 500 microg/mL of the extract reduced colony forming unit numbers of C. jejuni almost 10 000-fold within 12 hours. Similar decreases were seen against B. cereus, but over a longer time-frame. LC-MS analysis indicated the presence of reticuline and oxophoebine. Assessment of stability by MIC assay showed activity was heat-labile, with loss of activity greatest following high temperature treatments. Activity was relatively stable at refrigeration temperature. These results indicate A. squamosa has broad-spectrum but heat-labile activity against foodborne bacterial pathogens, and bactericidal activity against B. cereus and C. jejuni. This bactericidal activity is not sufficiently rapid for A. squamosa to be used as a food sanitizer, but the extract could potentially be developed as an additive for refrigerated foods, or a modern treatment for foodborne illness.

Full Text Available Over the past decade there has been a growing recognition of the involvement of the home in several public health and hygiene issues. Perhaps the best understood of these issues is the role of the home in the transmission and acquisition of foodborne disease. The incidence of foodborne disease is increasing globally. Although foodborne disease data collection systems often miss the mass of home-based outbreaks of sporadic infection, it is now accepted that many cases of foodborne illness occur as a result of improper food handling and preparation by consumers in their own kitchens. Some of the most compelling evidence has come from the international data on Salmonella species and Campylobacter species infections.

Pressure ulcer prevention in patients with advanced illness.

White-Chu, E Foy; Reddy, Madhuri

2013-03-01

Pressure ulcers can be challenging to prevent, particularly in patients with advanced illnesses. This review summarizes the relevant literature since 2011. Through a MEDLINE and CINAHL database search from January 1, 2011 to June 1, 2012, a total of 14 abstracts were found addressing the prevention of pressure ulcers in persons with advanced illness. Search terms included pressure ulcer, prevention, and control. Advanced illness was defined as patients transitioning from curative to supportive and palliative care. Ten original studies and four review articles specifically addressed pressure ulcer prevention. There were four articles that specifically addressed patients with advanced illness. The studies varied in quality. One systematic review, one randomized controlled trial, three prospective trials, two retrospective trials, one cost-effectiveness analysis, one quality improvement project, one comparative descriptive design, and four review articles were found. The interventions for pressure ulcer prevention were risk assessment, repositioning, surface selection, nutritional support and maintenance of skin integrity with or without incontinence. The quality of pressure ulcer prevention studies in persons with advanced illness is poor. Increased number and higher quality studies are needed to further investigate this important topic for these fragile patients.

Listeriosis is characterized by bacteremia or meningitis. We searched for listeriosis case series and outbreak investigations published in English by 2013, and assessed the strength of evidence for foodborne acquisition among patients who ate hospital food. We identified 30 reports from 13 countries. Among the case series, the median proportion of cases considered to be hospital-acquired was 25% (range, 9%-67%). The median number of outbreak-related illnesses considered to be hospital-acquired was 4.0 (range, 2-16). All patients were immunosuppressed in 18 of 24 (75%) reports with available data. Eight outbreak reports with strong evidence for foodborne acquisition in a hospital implicated sandwiches (3 reports), butter, precut celery, Camembert cheese, sausage, and tuna salad (1 report each). Foodborne acquisition of listeriosis among hospitalized patients is well documented internationally. The number of listeriosis cases could be reduced substantially by establishing hospital policies for safe food preparation for immunocompromised patients and by not serving them higher-risk foods.

Clostridium perfringens type A is a common source of foodborne illness (FBI) in humans. Vegetative cells sporulate in the small intestinal tract and produce the major pathogenic factor C. perfringens enterotoxin. Although sporulation plays a critical role in the pathogenesis of FBI, the mechanisms inducing sporulation remain unclear. Bile salts were shown previously to induce sporulation, and we confirmed deoxycholate (DCA)-induced sporulation in C. perfringens strain NCTC8239 cocultured with human intestinal epithelial Caco-2 cells. In the present study, we performed transcriptome analyses of strain NCTC8239 in order to elucidate the mechanism underlying DCA-induced sporulation. Of the 2,761 genes analyzed, 333 were up- or downregulated during DCA-induced sporulation and included genes for cell division, nutrient metabolism, signal transduction, and defense mechanisms. In contrast, the virulence-associated transcriptional regulators (the VirR/VirS system, the agr system, codY, and abrB) were not activated by DCA. DCA markedly increased the expression of signaling molecules controlled by Spo0A, the master regulator of the sporulation process, whereas the expression of spo0A itself was not altered in the presence or absence of DCA. The phosphorylation of Spo0A was enhanced in the presence of DCA. Collectively, these results demonstrated that DCA induced sporulation, at least partially, by facilitating the phosphorylation of Spo0A and activating Spo0A-regulated genes in strain NCTC8239 while altering the expression of various genes. Disease caused by Clostridium perfringens type A consistently ranks among the most common bacterial foodborne illnesses in humans in developed countries. The sporulation of C. perfringens in the small intestinal tract is a key event for its pathogenesis, but the factors and underlying mechanisms by which C. perfringens sporulates in vivo currently remain unclear.

Multiple current studies show that neuroinflammation may contribute to mental illness such as depression, anxiety, and mood disorder. Chronic inflammation in peripheral tissues is indicated by the increase of inflammatory marker like cytokine IL-6, TNF-α, and IL-1β. Pro-inflammatory cytokine in peripheral tissues can reach brain tissues and activate microglia and it causes neuroinflammation. Psychological stress may led peripheral and central inflammation. Activated microglia will produce pro-inflammatory cytokine, ROS, RNS, and tryptophan catabolizes. This neuroinflammation can promote metabolism changes of any neurotransmitter, such as serotonin, dopamine, and glutamate that will influence neurocircuit in the brain including basal ganglia and anterior cingulated cortex. It leads to mental illness. Exercise give contribution to reduce tissue inflammation. When muscle is contracting in an exercise, muscle will produce the secretion of cytokine like IL-6, IL-1ra, and IL-10. It will react as anti-inflammation and influence macrophage, T cell, monosit, protein Toll-Like Receptor (TLR), and then reduce neuroinflammation, characterised by the decrease of pro-inflammatory cytokine and prevent the activation of microglia in the brain. The objective of the present study is to review scientific articles in the literature related to the contribution of exercise to prevent and ease mental illness.

Foodborne diseases are important worldwide, resulting in considerable morbidity and mortality. To our knowledge, we present the first global and regional estimates of the disease burden of the most important foodborne bacterial, protozoal, and viral diseases. We synthesized data on the number of foodborne illnesses, sequelae, deaths, and Disability Adjusted Life Years (DALYs), for all diseases with sufficient data to support global and regional estimates, by age and region. The data sources included varied by pathogen and included systematic reviews, cohort studies, surveillance studies and other burden of disease assessments. We sought relevant data circa 2010, and included sources from 1990-2012. The number of studies per pathogen ranged from as few as 5 studies for bacterial intoxications through to 494 studies for diarrheal pathogens. To estimate mortality for Mycobacterium bovis infections and morbidity and mortality for invasive non-typhoidal Salmonella enterica infections, we excluded cases attributed to HIV infection. We excluded stillbirths in our estimates. We estimate that the 22 diseases included in our study resulted in two billion (95% uncertainty interval [UI] 1.5-2.9 billion) cases, over one million (95% UI 0.89-1.4 million) deaths, and 78.7 million (95% UI 65.0-97.7 million) DALYs in 2010. To estimate the burden due to contaminated food, we then applied proportions of infections that were estimated to be foodborne from a global expert elicitation. Waterborne transmission of disease was not included. We estimate that 29% (95% UI 23-36%) of cases caused by diseases in our study, or 582 million (95% UI 401-922 million), were transmitted by contaminated food, resulting in 25.2 million (95% UI 17.5-37.0 million) DALYs. Norovirus was the leading cause of foodborne illness causing 125 million (95% UI 70-251 million) cases, while Campylobacter spp. caused 96 million (95% UI 52-177 million) foodborne illnesses.

Epidemiology of foodborne diseases: a worldwide review.

Acute foodborne disease infections and intoxications are much more of a concern to governments and the food industry today than a few decades ago. Some of the factors that have led to this include the identification of new agents that have caused life-threatening conditions; the finding that traditional agents are being associated with foods that were of no concern previously: an increasing number of large outbreaks being reported; the impact of foodborne disease on children, the aging population and the immunocompromised; migrant populations demanding their traditional foods in the countries of settlement; the ease of worldwide shipment of fresh and frozen food; and the development of new food industries, including aquaculture. However, to meaningfully monitor increases or decreases in foodborne disease requires an effective surveillance system at the local, national and international levels. To date, resources have been limited for most countries and regions to do this, and our current knowledge is based, for the most part, on passive reporting mechanisms. Laboratory isolation data and reports of notifiable diseases have some value in observing timely changes in case numbers of some enteric diseases, but they usually do not indicate the reasons for these trends. Special epidemiological studies are useful for the area covered, but it is often questionable whether they can be extrapolated to other areas or countries. Outbreak investigations tell us that a certain set of circumstances led to illness and that another outbreak may occur under similar but not necessarily identical conditions. Control programmes have often been triggered by the conclusions from investigations of specific outbreaks. Unfortunately, the agent/ food combination leading to illness in many of the reported incidents were not predicted from existing databases, and no doubt foodborne agents will continue to surprise food control agencies in the foreseeable future. Nevertheless, data from around

Bacterial food-borne zoonoses.

Thorns, C J

2000-04-01

In many countries of the world, bacterial food-borne zoonotic infections are the most common cause of human intestinal disease. Salmonella and Campylobacter account for over 90% of all reported cases of bacteria-related food poisoning world-wide. Poultry and poultry products have been incriminated in the majority of traceable food-borne illnesses caused by these bacteria, although all domestic livestock are reservoirs of infection. In contrast to the enzootic nature of most Salmonella and Campylobacter infections, Salmonella Enteritidis caused a pandemic in both poultry and humans during the latter half of the 20th Century. Salmonella Typhimurium and Campylobacter appear to be more ubiquitous in the environment, colonising a greater variety of hosts and environmental niches. Verocytotoxin-producing Escherichia coli O157 (VTEC O157) also emerged as a major food-borne zoonotic pathogen in the 1980s and 1990s. Although infection is relatively rare in humans, clinical disease is often severe, with a significant mortality rate among the young and elderly. The epidemiology of VTEC O157 is poorly understood, although ruminants, especially cattle and sheep, appear to be the major source of infection. The dissemination of S. Enteritidis along the food chain is fairly well understood, and control programmes have been developed to target key areas of poultry meat and egg production. Recent evidence indicates that these control programmes have been associated with an overall reduction of S. Enteritidis along the food chain. Unfortunately, existing controls do not appear to reduce the levels of Campylobacter and VTEC O157 infections. Future control strategies need to consider variations in the epidemiologies of food-borne zoonotic infections, and apply a quantitative risk analysis approach to ensure that the most cost-effective programmes are developed.

Pomegranate juice (PJ) has gained popularity because of its associated antioxidant, antimicrobial, anticancer, and anti-inflammatory properties. However, its effects against epidemiologically significant foodborne viruses have not been investigated. In the absence of culturable human noroviruses, feline calicivirus (FCV-F9), murine norovirus (MNV-1), and MS2 (ssRNA) bacteriophage were used as foodborne viral surrogates. The aim of this research was to study the effects of PJ and pomegranate polyphenols (PP) on foodborne viral infectivity. Viruses at high (∼ 7 log(10) PFU/mL) or low (∼ 5 log(10) PFU/mL) titers were mixed with equal volumes of PJ, 8, 16, and 32 mg/mL of PP, or water (control) and incubated for 1 h at room temperature. Viral infectivity after treatments was evaluated using standardized plaque assays. PJ decreased the titer of FCV-F9, MNV-1, and MS2 by 2.56, 1.32, and 0.32 log(10) PFU/mL, respectively, for low titers and 1.20, 0.06, and 0.63 log(10) PFU/mL, respectively, for high titers. Interestingly, FCV-F9 was undetectable after exposure to the three tested PP solutions using both low and high titers. MNV-1 at low initial titers was reduced by 1.30, 2.11, and 3.61 log(10) PFU/mL and at high initial titers by 1.56, 1.48, and 1.54 log(10) PFU/mL with 4, 8, and 16 mg/mL of PP treatment, respectively. MS2 at low initial titers was reduced by 0.41, 0.45, and 0.93 log(10) PFU/mL and at high initial titers by 0.32, 0.41, and 0.72 log(10) PFU/mL after 4, 8, and 16 mg/mL of PP treatment, respectively. PJ and PP resulted in titer reductions of foodborne virus surrogates after 1 h exposure, showing promise for use in hurdle technologies and/or for therapeutic or preventive use. To suggest the use of PJ and PP as natural remedies for foodborne viral illness prevention, their mechanism of action against viral infectivity needs to be further investigated.

Some populations appear to be particularly vulnerable to the development of psychiatric symptomatology related to life events and biologic or social/cultural factors. Such groups include individuals who have experienced traumatic events, military personnel, individuals with serious medical conditions, postpartum women, and immigrants. This study reviews the literature regarding primary prevention of psychiatric disorders in special populations and identifies a variety of universal, selective, and indicated prevention measures aimed at minimizing the psychiatric sequelae in these groups. The authors reviewed the literature regarding the prevention of psychiatric symptoms in trauma/abuse victims, individuals in the military, oncology patients, patients with diabetes, pregnant/postpartum women, and immigrants. The literature on primary prevention of psychiatric illness in the special populations identified is rather limited. Universal prevention may be beneficial in some instances through public awareness campaigns and disaster planning. In other instances, more specific and intensive interventions for individuals at high risk of psychiatric illness may improve outcomes, for example, crisis counseling for those who have experienced severe trauma. Primary prevention of psychiatric illness may be an attainable goal via implementation of specific universal, selected, and indicated primary prevention measures in special populations.

Paralympic athletes have unique preexisting medical conditions that predispose them to increased risk of illness, but data are limited to studies conducted during the last 3 Paralympic Games. This article reviews the epidemiology of illness (risk, patterns, and predictors) in Paralympic athletes and provides practical guidelines for illness prevention. The incidence rate of illness (per 1000 athlete-days) in Paralympic athletes is high in Summer (10.0-13.2) and Winter (18.7) Paralympic Games. The authors propose general and specific guidelines on preventative strategies regarding illness in these athletes. Copyright © 2018 Elsevier Inc. All rights reserved.

Full Text Available The incidence of foodborne diseases has increased over the years and resulted in major public health problem globally. Foodborne pathogens can be found in various foods and it is important to detect foodborne pathogens to provide safe food supply and to prevent foodborne diseases. The conventional methods used to detect foodborne pathogen are time consuming and laborious. Hence, a variety of methods have been developed for rapid detection of foodborne pathogens as it is required in many food analyses. Rapid detection methods can be categorized into nucleic acid-based, biosensor-based and immunological-based methods. This review emphasizes on the principles and application of recent rapid methods for the detection of foodborne bacterial pathogens. Detection methods included are simple polymerase chain reaction (PCR, multiplex PCR, real-time PCR, nucleic acid sequence-based amplification (NASBA, loop-mediated isothermal amplification (LAMP and oligonucleotide DNA microarray which classified as nucleic acid-based methods; optical, electrochemical and mass-based biosensors which classified as biosensor-based methods; enzyme-linked immunosorbent assay (ELISA and lateral flow immunoassay which classified as immunological-based methods. In general, rapid detection methods are generally time-efficient, sensitive, specific and labor-saving. The developments of rapid detection methods are vital in prevention and treatment of foodborne diseases.

Mental illness is prevalent across the globe and affects multiple aspects of life. Despite advances in treatment, there is little evidence that prevalence rates of mental illness are falling. While the prevention of cardiovascular disease and cancers are common in the policy dialogue and in service delivery, the prevention of mental illness remains a neglected area. There is accumulating evidence that mental illness is at least partially preventable, with increasing recognition that its antecedents are often found in infancy, childhood, adolescence and youth, creating multiple opportunities into young adulthood for prevention. Developing valid and reproducible methods for translating the evidence base in mental illness prevention into actionable policy recommendations is a crucial step in taking the prevention agenda forward. Building on an aetiological model of adult mental illness that emphasizes the importance of intervening during infancy, childhood, adolescence and youth, we adapted a workforce and service planning framework, originally applied to diabetes care, to the analysis of the workforce and service structures required for best-practice prevention of mental illness. The resulting framework consists of 6 steps that include identifying priority risk factors, profiling the population in terms of these risk factors to identify at-risk groups, matching these at-risk groups to best-practice interventions, translation of these interventions to competencies, translation of competencies to workforce and service estimates, and finally, exploring the policy implications of these workforce and services estimates. The framework outlines the specific tasks involved in translating the evidence-base in prevention, to clearly actionable workforce, service delivery and funding recommendations. The framework describes the means to deliver mental illness prevention that the literature indicates is achievable, and is the basis of an ongoing project to model the workforce

Foodborne disease surveillance aims to reduce the burden of illness due to contaminated food. There are several different types of surveillance systems, including event-based surveillance, indicator-based surveillance, and integrated food chain surveillance. These approaches are not mutually exclusive, have overlapping data sources, require distinct capacities and resources, and can be considered a hierarchy, with each level being more complex and resulting in a greater ability to detect and control foodborne disease. Event-based surveillance is generally the least resource-intensive system and makes use of informal data sources. Indicator-based surveillance is seen as traditional notifiable disease surveillance and consists of routinely collected data. Integrated food chain surveillance is viewed as the optimal practice for conducting continuous risk analysis for foodborne diseases, but also requires significant ongoing resources and greater multisectoral collaboration compared to the other systems. Each country must determine the most appropriate structure for their surveillance system for foodborne diseases based on their available resources. This review explores the evidence on the principles, minimum capabilities, and minimum requirements of each type of surveillance and discusses examples from a range of countries. This review forms the evidence base for the Strengthening the Surveillance and Response for Foodborne Diseases: A Practical Manual.

Baumann-Popczyk, Anna; Sadkowska-Todys, Małgorzata

2012-01-01

The purpose of this paper was to describe the epidemiology of foodborne outbreaks in Poland in 2010. The evaluation of the epidemiological situation was based on data from outbreak investigation forms, reported by Sanitary and Epidemiological Stations to the Department of Epidemiology, NIPH-NIH. In 2010 a notable increase in the number of cases reported with a bacterial infection was observed. This increase however did not exceeded the median number of cases reported in 2004-2008. In 2010 392 foodborne infections and food poisoning involving 6994 cases (outbreaks involving 4 person or more) and 145 foodborne outbreaks (where 2-3 persons became ill were reported. S. Enteritidis was the most frequently etiological agent in outbreaks associated with bacterial infection (32.9% of outbreaks 22.4% cases). Viruses caused 26% of outbreaks affected 30% of cases. In 38.3% outbreaks the etiological agent could not be established. The main vehicle of foodborne outbreaks were meals prepared from (> 3) raw meats (4.6% of outbreaks, 10.9% cases) and meals prepared using milk and eggs (9.9% of outbreaks 5.7% cases). The most frequent places of contamination included farms who produced goods for human consumption (11.5% of outbreaks, 5.0% of cases). Private residences (113 outbreaks with 745 cases) and hospitals were the most common place where food poisoning outbreaks occurred. In 2010 there were 6 outbreaks where more than 100 people were affected in these settings. Like in previous years, in 2010 the etiological agents, vehicle and sources of infection were not identified in most foodborne outbreaks. In order to decrease the number of outbreaks with undetermined etiological agent, the spectrum of routine laboratory tests of samples taken in outbreaks should be broaden.

Irradiation's promise: fewer foodborne illnesses?

International Nuclear Information System (INIS)

Roberts, T.

1986-01-01

Food irradiation offers a variety of potential benefits to the food supply. It can delay ripening and sprouting of fruits and vegetables, and substitute for chemical fumigants to kill insects. However, one of the most important benefits of food irradiation is its potential use for destroying microbial pathogens that enter the food supply, including the two most common disease causing bacteria: salmonella and campylobacter. Animal products are one of the primary carriers of pathogens. Food borne illnesses are on the rise, and irradiation of red meats and poultry could significantly reduce their occurrence. Food irradiation should be examined more closely to determine its possible benefits in curtailing microbial diseases

An Outbreak of Foodborne Botulism in Ontario

Directory of Open Access Journals (Sweden)

Mona R Loutfy

2003-01-01

Full Text Available Botulism is a rare paralytic illness resulting from a potent neurotoxin produced by Clostridium botulinum. Botulism in Canada is predominately due to C botulinum type E and affects mainly the First Nations and Inuit populations. The most recent outbreak of botulism in Ontario was in Ottawa in 1991 and was caused by C botulinum type A. We report an outbreak of foodborne type B botulism in Ontario, which implicated home-canned tomatoes. The outbreak was characterized by mild symptoms in two cases and moderately severe illness in one case. The investigation shows the importance of considering the diagnosis of botulism in patients presenting with cranial nerve and autonomic dysfunction, especially when combined with gastrointestinal complaints; it also highlights the importance of proper home canning technique.

Pathogenic bacteria can live asymptomatically within and on cattle and can enter the food chain but also can be transmitted to humans by fecal or direct animal contact. Reducing pathogenic bacterial incidence and populations within live cattle represents an important step in improving food safety. A broad range of preslaughter intervention strategies are being developed, which can be loosely classified as 1) directly antipathogen strategies, 2) competitive enhancement strategies (that use the microbiome's competitive nature against pathogens), and 3) animal management strategies. Included within these broad categories are such diverse methods as vaccination against foodborne pathogens, probiotics and prebiotics, bacterial viruses (i.e., bacteriophages), sodium chlorate feeding, and dietary and management changes that specifically alter the microbiome. The simultaneous application of 1 or more preharvest strategies has the potential to reduce human foodborne illnesses by erecting multiple hurdles preventing entry into humans. However, economic factors that govern producer profitability must be kept in mind while improving food safety.

Do leafy green vegetables and their ready-to-eat [RTE] salads carry a risk of foodborne pathogens?

Science.gov (United States)

Mercanoglu Taban, Birce; Halkman, A Kadir

2011-12-01

Over the past 10 years, there is an increasing demand for leafy green vegetables and their ready-to-eat (RTE) salads since people changed their eating habits because of healthier lifestyle interest. Nevertheless fresh leafy green vegetables and their RTE salads are recognized as a source of food poisoning outbreaks in many parts of the world. However, this increased proportion of outbreaks cannot be completely explained by increased consumption and enhanced surveillance of them. Both in Europe and in the USA, recent foodborne illness outbreaks have revealed links between some pathogens and some leafy green vegetables such as mostly lettuces and spinaches and their RTE salads since fresh leafy green vegetables carry the potential risk of microbiological contamination due to the usage of untreated irrigation water, inappropriate organic fertilizers, wildlife or other sources that can occur anywhere from the farm to the fork such as failure during harvesting, handling, processing and packaging. Among a wide range of pathogens causing foodborne illnesses, Escherichia coli O157:H7, Salmonella spp., and Listeria monocytogenes are the most common pathogens that contaminate leafy green vegetables. Children, the elderly, pregnant women and immunocompromised people are the most at risk for developing complications from foodborne illness as a result of eating contaminated leafy greens or their RTE salads. These outbreaks are mostly restaurant associated or they sometimes spread across several countries by international trade routes. This review summarizes current observations concerning the contaminated leafy green vegetables and their RTE salads as important vehicles for the transmission of some foodborne pathogens to humans.

Transmission may also be food-borne, but only few norovirus outbreak investigations have identified food items as likely vehicles of norovirus transmission through an analytical epidemiological study.During 7-9 January, 2009, 36 persons at a military base in Germany fell ill with acute gastroenteritis. Food from the military base's canteen was suspected as vehicle of infection, norovirus as the pathogen causing the illnesses. An investigation was initiated to describe the outbreak's extent, to verify the pathogen, and to identify modes of transmission and source of infection to prevent further cases. For descriptive analysis, ill persons were defined as members of the military base with acute onset of diarrhoea or vomiting between 24 December 2008, and 3 February 2009, without detection of a pathogen other than norovirus in stools. We conducted a retrospective cohort study within the headquarters company. Cases were military base members with onset of diarrhoea or vomiting during 5-9 January. We collected information on demographics, food items eaten at the canteen and contact to ill persons or vomit, using a self-administered questionnaire. We compared attack rates (AR) in exposed and unexposed persons, using bivariable and multivariable logistic regression modelling. Stool specimens of ill persons and canteen employees, canteen food served during 5-7 January and environmental swabs were investigated by laboratory analysis. Overall, 101/815 (AR 12.4%) persons fell ill between 24 December 2008 and 3 February 2009. None were canteen employees. Most persons (n = 49) had disease onset during 7-9 January. Ill persons were a median of 22 years old, 92.9% were male. The response for the cohort study was 178/274 (72.1%). Of 27 cases (AR 15.2%), 25 had eaten at the canteen and 21 had consumed salad. Salad consumption on 6 January (aOR: 8.1; 95%CI: 1.5-45.4) and 7 January (aOR: 15.7; 95%CI: 2.2-74.1) were independently

Intervention strategies for control of foodborne pathogens

Science.gov (United States)

Juneja, Vijay K.

The increasing numbers of illnesses associated with foodborne pathogens such as Listeria monocytogenes and Escherichia coli O157:H7, has renewed concerns about food safety because of consumer preferences for minimally processed foods that offer convenience in availability and preparation. Accordingly, the need for better control of foodborne pathogens has been paramount in recent years. Mechanical removal of microorganisms from food can be accomplished by centrifugation, filtration, trimming and washing. Cleaning and sanitation strategies can be used for minimizing the access of microorganisms in foods from various sources. Other strategies for control of foodborne pathogens include established physical microbiocidal treatments such as ionizing radiation and heating. Research has continued to demonstrate that food irradiation is a suitable process to control and possibly eliminate foodborne pathogens, for example Listeria monocytogenes and Escherichia coli O157:H7, from a number of raw and cooked meat and poultry products. Heat treatment is the most common method in use today for the inactivation of microorganisms. Microorganisms can also be destroyed by nonthermal treatments, such as application of high hydrostatic pressure, pulsed electric fields, oscillating magnetic fields or a combination of physical processes such as heat-irradiation, or heat-high hydrostatic pressure, etc. Each of the non-thermal technologies has specific applications in terms of the types of food that can be processed. Both conventional and newly developed physical treatments can be used in combination for controlling foodborne pathogens and enhancing the safety and shelf life of foods. Recent research has focused on combining traditional preservation factors with emerging intervention technologies. However, many key issues still need to be addressed for combination preservation factors or technologies to be useful in the food industry to meet public demands for foods with enhanced safety

Listeriosis Prevention Knowledge Among Pregnant Women in the USA

Directory of Open Access Journals (Sweden)

Ruth Lynfield

2005-01-01

Full Text Available Background: Listeriosis is a food-borne disease often associated with ready-to-eat foods. It usually causes mild febrile gastrointestinal illness in immunocompetent persons. In pregnant women, it may cause more severe infection and often crosses the placenta to infect the fetus, resulting in miscarriage, fetal death or neonatal morbidity. Simple precautions during pregnancy can prevent listeriosis. However, many women are unaware of these precautions and listeriosis education is often omitted from prenatal care.

A hospital cafeteria-related food-borne outbreak due to Bacillus cereus: unique features.

Baddour, L M; Gaia, S M; Griffin, R; Hudson, R

1986-09-01

Although Bacillus cereus is a well-known cause of food-borne illness, hospital-related outbreaks of food-borne disease due to B. cereus have rarely been documented. We report a hospital employee cafeteria outbreak due to foods contaminated with B. cereus in which an outside caterer was employed to prepare the suspect meals. Data were collected from 249 of 291 employees who had eaten either of the two meals. With a mean incubation period of 12.5 hours, 64% (160 of 249) of employees manifested illness. Symptoms, which averaged 24.3 hours in duration, included diarrhea (96.3%), abdominal cramps (90%), nausea (50.6%), weakness (24.7%), and vomiting (13.8%). Eighty-seven employees sought medical attention, 84 of whom were seen in an emergency room. Although a significant difference was not demonstrated in food-specific attack rates, B. cereus was cultured from both rice and chicken items that were served at both meals. Sixty-three employees submitted stools for culture that grew no enteric pathogens, but none were examined for B. cereus. This food-borne outbreak demonstrates: the need for hospital kitchen supervisors to ensure proper handling of food when outside caterers are employed; that significant differences in food-specific attack rates may not be demonstrated in outbreaks, which may be related to several factors; and the importance of notifying microbiology laboratory personnel when B. cereus is a suspect enteric pathogen, since many laboratories do not routinely attempt to identify this organism in stool specimens.

Three outbreaks of foodborne botulism caused by unsafe home canning of vegetables--Ohio and Washington, 2008 and 2009.

Foodborne botulism is a potentially fatal paralytic illness caused by ingestion of neurotoxin produced by the spore-forming bacterium Clostridium botulinum. Historically, home-canned vegetables have been the most common cause of botulism outbreaks in the United States. During 2008 and 2009, the Centers for Disease Control and Prevention (CDC) and state and local health departments in Ohio and Washington State investigated three outbreaks caused by unsafe home canning of vegetables. We analyzed CDC surveillance data for background on food vehicles that caused botulism outbreaks from 1999 to 2008. For the three outbreaks described, patients and their family members were interviewed and foods were collected. Laboratory testing of clinical and food samples was done at the respective state public health laboratories. From 1999 to 2008, 116 outbreaks of foodborne botulism were reported. Of the 48 outbreaks caused by home-prepared foods from the contiguous United States, 38% (18) were from home-canned vegetables. Three outbreaks of Type A botulism occurred in Ohio and Washington in September 2008, January 2009, and June 2009. Home-canned vegetables (green beans, green bean and carrot blend, and asparagus) served at family meals were confirmed as the source of each outbreak. In each instance, home canners did not follow canning instructions, did not use pressure cookers, ignored signs of food spoilage, and were unaware of the risk of botulism from consuming improperly preserved vegetables. Home-canned vegetables remain a leading cause of foodborne botulism. These outbreaks illustrate critical areas of concern in current home canning and food preparation knowledge and practices. Similar gaps were identified in a 2005 national survey of U.S. adults. Botulism prevention efforts should include targeted educational outreach to home canners.

On 7 and 11 July 2007, health officials in Texas and Indiana, respectively, reported 4 possible cases of type A foodborne botulism to the US Centers for Disease Control and Prevention. Foodborne botulism is a rare and sometimes fatal illness caused by consuming foods containing botulinum neurotoxin. Investigators reviewed patients' medical charts and food histories. Clinical specimens and food samples were tested for botulinum toxin and neurotoxin-producing Clostridium species. Investigators conducted inspections of the cannery that produced the implicated product. Eight confirmed outbreak associated cases were identified from Indiana (n = 2), Texas (n = 3), and Ohio (n = 3). Botulinum toxin type A was identified in leftover chili sauce consumed by the Indiana patients and 1 of the Ohio patients. Cannery inspectors found violations of federal canned-food regulations that could have led to survival of Clostridium botulinum spores during sterilization. The company recalled 39 million cans of chili. Following the outbreak, the US Food and Drug Administration inspected other canneries with similar canning systems and issued warnings to the industry about the danger of C. botulinum and the importance of compliance with canned food manufacturing regulations. Commercially produced hot dog chili sauce caused these cases of type A botulism. This is the first US foodborne botulism outbreak involving a commercial cannery in >30 years. Sharing of epidemiologic and laboratory findings allowed for the rapid identification of implicated food items and swift removal of potentially deadly products from the market by US food regulatory authorities.

[Prevention groups for school-age children of mentally ill parents ("Auryn Groups")].

Science.gov (United States)

Dierks, H

2001-09-01

Children of psychiatrically ill parents have a high risk themselves to develop a psychiatric illness in adulthood. Prevention aims at strengthening the resilience of these children and reducing psychosocial risk factors. This article found and describes a theoretical concept of prevention groups for children in schoolage (7-16 years) whose parents are psychiatrically ill. First practical experiences are depicted. The Hamburgian model of prevention works with closed and temporary limited groups of children as well as with the parents. It is based on supporting the children's existing coping strategies and the children are encouraged to exchange their individual experiences of the relationships within their families. One conclusion was, that the main thematic emphasis varied considerably depending on the age of the children.

Pediatric heat-related illness: recommendations for prevention and management [digest].

Science.gov (United States)

Dunn, Roberta J; Kim, Tommy Y; Chaudhari, Pradip

2017-08-22

Infants, children, and adolescents are at increased risk for heat-related illness due to their inability to remove themselves from dangerous environments. Evidence shows that morbidity and mortality from heat illness is related to the length of time core temperature is elevated, so rapid reduction and accurate serial measurements are crucial to prevention of organ system damage and death. The primary methods of patient cooling are conduction (ice-water immersion, cold packs) and convection (moisture and moving air). The choice of method used may depend on availability of equipment, but there is evidence that can guide optimal use of resources. This issue presents evidence-based recommendations and best practices in heat-illness resuscitation, including managing children who are obese, have special needs or take medications, and advocacy for prevention strategies.

Foodborne disease and the preventive role of food irradiation

International Nuclear Information System (INIS)

Moy, D.

1992-01-01

In view on the enormous health and economic consequences of foodborne diseases, irradiation decontamination and disinfestation of pathogen-containing foods must be considered one of the most significant recent contributions to public health made by food science and technology. Food irradiation has an important part to play with in the promotion of food safety and in the reduction of food losses. The unwarranted rejection of the process, often based on a lack of understanding of what food irradiation entails, may hamper its use in most countries that could benefit most

Food-borne norovirus-outbreak at a military base, Germany, 2009

Directory of Open Access Journals (Sweden)

Hoehne Marina

2010-02-01

Full Text Available Abstract Background Norovirus is often transmitted from person-to-person. Transmission may also be food-borne, but only few norovirus outbreak investigations have identified food items as likely vehicles of norovirus transmission through an analytical epidemiological study. During 7-9 January, 2009, 36 persons at a military base in Germany fell ill with acute gastroenteritis. Food from the military base's canteen was suspected as vehicle of infection, norovirus as the pathogen causing the illnesses. An investigation was initiated to describe the outbreak's extent, to verify the pathogen, and to identify modes of transmission and source of infection to prevent further cases. Methods For descriptive analysis, ill persons were defined as members of the military base with acute onset of diarrhoea or vomiting between 24 December 2008, and 3 February 2009, without detection of a pathogen other than norovirus in stools. We conducted a retrospective cohort study within the headquarters company. Cases were military base members with onset of diarrhoea or vomiting during 5-9 January. We collected information on demographics, food items eaten at the canteen and contact to ill persons or vomit, using a self-administered questionnaire. We compared attack rates (AR in exposed and unexposed persons, using bivariable and multivariable logistic regression modelling. Stool specimens of ill persons and canteen employees, canteen food served during 5-7 January and environmental swabs were investigated by laboratory analysis. Results Overall, 101/815 (AR 12.4% persons fell ill between 24 December 2008 and 3 February 2009. None were canteen employees. Most persons (n = 49 had disease onset during 7-9 January.

To evaluate progress toward prevention of enteric and foodborne illnesses in the United States, the Foodborne Diseases Active Surveillance Network (FoodNet) monitors the incidence of laboratory-confirmed infections caused by nine pathogens transmitted commonly through food in 10 U.S. sites. This report summarizes preliminary 2015 data and describes trends since 2012. In 2015, FoodNet reported 20,107 confirmed cases (defined as culture-confirmed bacterial infections and laboratory-confirmed parasitic infections), 4,531 hospitalizations, and 77 deaths. FoodNet also received reports of 3,112 positive culture-independent diagnostic tests (CIDTs) without culture-confirmation, a number that has markedly increased since 2012. Diagnostic testing practices for enteric pathogens are rapidly moving away from culture-based methods. The continued shift from culture-based methods to CIDTs that do not produce the isolates needed to distinguish between strains and subtypes affects the interpretation of public health surveillance data and ability to monitor progress toward prevention efforts. Expanded case definitions and strategies for obtaining bacterial isolates are crucial during this transition period.

To study the antibiotic susceptibility of foodborne Listeria monocytogenes in China. The susceptibilities of 476 strains of foodborne Listeria monocytogenes to antibiotics were determined in Broth Microdilution Susceptibility Testing in Clinical and Laboratory Standards Institute. The antibiotics of gentamicin, ampicillin, penicillin, tetracycline, doxycycline, imipenem, erythromycin, ciprofloxacin, levofloxacin, cephalothin, rifampin, vancomycin, chloramphenicol, Trimethoprim-sulfamethoxazole, ampicillin-sulbactam were used. The rates of antibiotic resistance in 467 is olates were 4.5%. Tetracycline resistance was most prevalent, accouting for 4.07% . The foods that the rates of antibiotic resistance were highest were vegetable (10%). Among 14 provinces, Jilin, Hubei and Hebei were the third top, the rate of which were 19.6% and 9.1% and 8%, respectively. It was suggested that antibiotic resistance exists in foodborne Listeria monocytogenes to a certain extent in China. It should pay more attention to the use of drugs in prevention and clinic treatment to reduce the antibiotic resistant strains.

Although health departments routinely inspect restaurants to assess compliance with established hygienic standards, few data are available on the effectiveness of these efforts in preventing foodborne disease. The study reported here assessed the impact on foodborne-disease hospitalizations in Los Angeles County of a restaurant hygiene grading system that utilized publicly posted grade cards. The grading systm was introduced in January 1998. Hospital discharge data on foodborne-disease hospitalizations were analyzed for Los Angeles County and, as a control, for the rest of California during the period 1993-2000. Ordinary least-squares regression analysis was done to measure the effect of the grading progam on these hospitalizations. After baseline temporal and geographic trends were adjusted for, the restaurant hygiene grading program was associated with a 13.1 percent decrease (p restaurant hygiene grading with public posting of results is an effective intervention for reducing the burden of foodborne disease.

Food preparers in families with young children are responsible for safe food preparation and handling to prevent foodborne illness. To explore the food safety perceptions, beliefs, and practices of primary food preparers in families with children 10 years of age and younger, a mixed methods convergent parallel design and constructs of the Health Belief Model were used. A random sampling of 72 primary food handlers (36.2±8.6 years of age, 88% female) within young families in urban and rural areas of two Midwestern states completed a knowledge survey and participated in ten focus groups. Quantitative data were analyzed using SPSS. Transcribed interviews were analyzed for codes and common themes. Forty-four percent scored less than the average knowledge score of 73%. Participants believe children are susceptible to foodborne illness but perceive its severity to be low with gastrointestinal discomfort as the primary outcome. Using safe food handling practices and avoiding inconveniences were benefits of preventing foodborne illness. Childcare duties, time and knowledge were barriers to practicing food safety. Confidence in preventing foodborne illness was high, especially when personal control over food handling is present. The low knowledge scores and reported practices revealed a false sense of confidence despite parental concern to protect their child from harm. Food safety messages that emphasize the susceptibility and severity of foodborne illness in children are needed to reach this audience for adoption of safe food handling practices.

Attending Weak Signals: The Prevention of Work-related Illnesses

Directory of Open Access Journals (Sweden)

Roy Liff

2017-06-01

Full Text Available This article examines the characteristics of communication among managers, human resource (HR experts, and occupational health care specialists, as they deal with such informal information as weak signals in the prevention of work-related illnesses, using a theoretical framework in which the prevention of work-related illness is analogous to theory on crisis management. This is a qualitative study in which individual and focus-group interviews were conducted in a Swedish context with occupational health care specialists, managers, and HR experts. The results suggest that organizational solutions have failed and continue to fail at controlling workers’ health problems, although the main difficulty is not in identifying the ‘right’ individually oriented weak signals. Rather, it is upper management’s reliance on formal information (e.g., statistics and surveys – because of the difficulty in supplementing it with informal information (e.g., rumors and gossip – that makes it difficult to improve traditional health and safety work

The purpose of the study is to assess the epidemiological situation of food poisonings and infections in Poland in 2013. The evaluation was based on the analysis of information from reports of epidemiological investigations in outbreaks of food poisonings and infections, submitted by the sanitary-epidemiological stations to the Department of Epidemiology, NIZP-PZH annual bulletins (Czarkowski MP et al. "Infectious diseases and poisonings in Poland", 2006-2013. Warsaw, NIPH-NIH and GIS). In 2013 a further decrease in the number of infections and intoxications with bacterial etiology and an increase in the infections of viral etiology was observed. Furthermore 2013 is another year with low number of cases of trichinellosis (9 cases in total). In 2013 a total number of 491 foodborne infections and intoxications outbreaks were reported in which there were 29,179 persons exposed and 5,664 (including 2 193 children up to 14 years of age) persons ill. Hospitalization was required for 1,445 persons. The most frequent etiological agent in those outbreaks was Salmonella spp.--which was responsible for 36,3% of outbreaks and 21,5% of cases. Viruses were responsible for 29,7 of outbreaks and 45,7 cases, in 19,3% of outbreaks no etiological agent was established. Like in 2012 the most frequent vehicle were dishes made from eggs and milk combined with eggs (9,4% of outbreaks). In 65% of outbreaks reported no vehicle could be found. Moreover in 2013 a total number of 3 outbreaks in which more than 100 cases were reported. The increase in the number of foodborne outbreaks of viral etiology shows the need of adjustment some aspects of epidemiological investigations especially such features as: laboratory conformation of etiological agent of ill persons as well as persons involved in the food processing and meals preparing and the aspect of food samples testing.

Respiratory illness continues to exert a burden on hajj pilgrims in Makkah. The purpose of this study is to determine the prevalence of respiratory illness and its associated factors among Malaysian hajj pilgrims in 2013 and to describe its preventive measures. A cross-sectional study was conducted in Makkah and Malaysia during the 2013 hajj season. A self-administered proforma on social demographics, previous experience of hajj or umrah, smoking habits, co-morbid illness and practices of preventive measures against respiratory illness were obtained. A total of 468 proforma were analysed. The prevalence of the respiratory illness was 93.4% with a subset of 78.2% fulfilled the criteria for influenza-like illness (ILI). Most of them (77.8%) had a respiratory illness of food supplement. Malaysian hajj pilgrims with previous experience of hajj (OR 0.24; 95% CI 0.10-0.56) or umrah (OR 0.19; 95% CI 0.07-0.52) and those who have practiced good hand hygiene (OR 0.35; 95% CI 0.16-0.79) were found to be significantly associated with lower risk of having respiratory illness. Otherwise, pilgrims who had contact with those with respiratory illness (OR 2.61; 95% CI 1.12-6.09) was associated with higher risk. The prevalence of respiratory illness remains high among Malaysian hajj pilgrims despite having some practices of preventive measures. All preventive measures which include hand hygiene, wearing face masks and influenza vaccination must be practiced together as bundle of care to reduce respiratory illness effectively. © The Author 2016.

Hans Michélsen

2014-05-01

Full Text Available Psychological strain in working life is gaining ever more attention. Health care workers are often under extreme emotional stress, which can become so overwhelming that they show signs of mental ill-health. This project aimed to develop a model for sustainable psychological support within a hospital clinic to prevent mental ill-health among employees. Mental strains at work and mental ill-health among clinic employees were mapped out, after which interventions for psychological support were designed in collaboration with employees. The interventions were conducted over one year and evaluated. Throughout the process the clinic received continuous feedback. Both questionnaires and interviews were used. The results of identifying mental strains and conducting interventions showed that employees experienced mental strain at work and perceived a need for support. Intervention evaluations showed that the project provided support, new insights, and an increased acceptance for long-term prevention of mental strain. Quantitative and qualitative methodologies supported the results. The conclusion was that increased legitimacy for mental strain at work and continuous feedback between clinic management and employees, as well as organizational circumstances are important factors when developing long-term intervention programs with various forms of psychological support.

2014-07-01

To investigate the effects of a suicide prevention programme on the levels of depression, self-esteem, suicidal ideation and spirituality in patients with mental illness. Instances of suicide have significant correlations with depression, low self-esteem, suicidal ideation and a low level of spirituality in the victims. Therefore, addressing depression, low self-esteem and suicidal ideation as suicide risk factors and increasing levels of spirituality can constitute an effective programme to prevent suicide among patients with mental illness. The study was a quasi-experimental study with a nonequivalent control group, nonsynchronised design. The study sample consisted of 45 patients with mental illness who had been admitted to the psychiatric unit in a university hospital in South Korea. The patients were assigned to control and experimental groups of 23 and 22 members, respectively. The suicide prevention programme was conducted with the experimental group over four weeks and included eight sessions (two per week). The control group received only routine treatments in the hospital. The experimental group that participated in the programme had significantly decreased mean scores for depression and suicidal ideation compared with the control group. However, there were no significant differences in the mean scores for self-esteem and spirituality between the groups. The suicide prevention programme might be usefully applied as a nursing intervention for patients hospitalised in psychiatric wards or clinics where the goals are to decrease depression and suicidal ideation. Typical treatments for hospitalised patients with mental illness are not enough to prevent suicide. Intervention for suicide prevention needs to apply an integrated approach. The suicide prevention programme using an integrated approach is more effective in reducing depression and suicidal ideation in patients with mental illness than applying routine treatments in the hospital. © 2013 John Wiley

Foodborne Campylobacter: Infections, Metabolism, Pathogenesis and Reservoirs

Full Text Available Campylobacter species are a leading cause of bacterial-derived foodborne illnesses worldwide. The emergence of this bacterial group as a significant causative agent of human disease and their propensity to carry antibiotic resistance elements that allows them to resist antibacterial therapy make them a serious public health threat. Campylobacter jejuni and Campylobacter coli are considered to be the most important enteropathogens of this genus and their ability to colonize and survive in a wide variety of animal species and habitats make them extremely difficult to control. This article reviews the historical and emerging importance of this bacterial group and addresses aspects of the human infections they cause, their metabolism and pathogenesis, and their natural reservoirs in order to address the need for appropriate food safety regulations and interventions.

Internationally human enteric viruses, such as norovirus (NoV) and hepatitis A virus (HAV), are frequently associated with shellfish related foodborne disease outbreaks, and it has been suggested that acceptable NoV limits based on end-point testing be established for this high risk food group. Currently, shellfish safety is generally managed through the use of indicators of faecal contamination. Between July 2014 and August 2015, a national prevalence survey for NoV and HAV was done in Australian oysters suitable for harvest. Two sampling rounds were undertaken to determine baseline levels of these viruses. Commercial Australian growing areas, represented by 33 oyster production regions in New South Wales, South Australia, Tasmania and Queensland, were included in the survey. A total of 149 and 148 samples were collected during round one and two of sampling, respectively, and tested for NoV and HAV by quantitative RT-PCR. NoV and HAV were not detected in oysters collected in either sampling round, indicating an estimated prevalence for these viruses in Australian oysters of oysters was consistent with epidemiological evidence, with no oyster-related foodborne viral illness reported during the survey period.

Working with Individuals Who Provide Nursing Care to Educate Older Adults about Foodborne Illness Prevention: The Food Safety Because You Care! Intervention

Directory of Open Access Journals (Sweden)

Kelly C. Wohlgenant

2015-01-01

Full Text Available Older adults are more susceptible to foodborne infections than younger adults and many older adults do not follow recommended food safety practices. This study implemented the Food Safety Because You Care! program with 88 individuals in the United States who provide nursing care to older adult patients and subsequently surveyed them. The majority of respondents had favorable opinions of the program. Following program exposure, many of the respondents advised their older adult patients about food safety. The findings from this study suggest that the program is a useful tool that can assist those who provide nursing care as they interact with their older patients and lead them to positively influence older adults’ food safety practices. However, more research is needed to examine changes in providers’ behaviors as a result of program exposure and the accompanying effect on older adults’ food safety practices.

Full Text Available An incident of food-borne poisoning causing illness in 37 victims due to ingestion of fried fish sticks occurred in September 2014, in Tainan city, southern Taiwan. Leftovers of the victims' fried fish sticks and 16 other raw fish stick samples from retail stores were collected and tested to determine the occurrence of histamine and histamine-forming bacteria. Two suspected fried fish samples contained 86.6 mg/100 g and 235.0 mg/100 g histamine; levels that are greater than the potential hazard action level (50 mg/100 g in most illness cases. Given the allergy-like symptoms of the victims and the high histamine content in the suspected fried fish samples, this food-borne poisoning was strongly suspected to be caused by histamine intoxication. Moreover, the fish species of suspected samples was identified as milkfish (Chanos chanos, using polymerase chain reaction direct sequence analysis. In addition, four of the 16 commercial raw milkfish stick samples (25% had histamine levels greater than the US Food & Drug Administration guideline of 5.0 mg/100 g for scombroid fish and/or products. Ten histamine-producing bacterial strains, capable of producing 373–1261 ppm of histamine in trypticase soy broth supplemented with 1.0% L-histidine, were identified as Enterobacter aerogenes (4 strains, Enterobacter cloacae (1 strain, Morganella morganii (2 strains, Serratia marcescens (1 strain, Hafnia alvei (1 strain, and Raoultella orithinolytica (1 strain, by 16S ribosomal DNA sequencing with polymerase chain reaction amplification.

Foodborne disease data collected during outbreak investigations are used to estimate the percentage of foodborne illnesses attributable to specific food categories. Current food categories do not reflect whether or how the food has been processed and exclude many multiple-ingredient foods. Representatives from three federal agencies worked collaboratively in the Interagency Food Safety Analytics Collaboration (IFSAC) to develop a hierarchical scheme for categorizing foods implicated in outbreaks, which accounts for the type of processing and provides more specific food categories for regulatory purposes. IFSAC also developed standard assumptions for assigning foods to specific food categories, including some multiple-ingredient foods. The number and percentage of outbreaks assignable to each level of the hierarchy were summarized. The IFSAC scheme is a five-level hierarchy for categorizing implicated foods with increasingly specific subcategories at each level, resulting in a total of 234 food categories. Subcategories allow distinguishing features of implicated foods to be reported, such as pasteurized versus unpasteurized fluid milk, shell eggs versus liquid egg products, ready-to-eat versus raw meats, and five different varieties of fruit categories. Twenty-four aggregate food categories contained a sufficient number of outbreaks for source attribution analyses. Among 9791 outbreaks reported from 1998 to 2014 with an identified food vehicle, 4607 (47%) were assignable to food categories using this scheme. Among these, 4218 (92%) were assigned to one of the 24 aggregate food categories, and 840 (18%) were assigned to the most specific category possible. Updates to the food categorization scheme and new methods for assigning implicated foods to specific food categories can help increase the number of outbreaks attributed to a single food category. The increased specificity of food categories in this scheme may help improve source attribution analyses, eventually

On March 25, 2009, the Ebeye Leroj Kitlang Memorial Health Center on the island of Ebeye in the Republic of the Marshall Islands was overwhelmed with over 100 patients presenting for vomiting and diarrhea. Epidemiologic investigation revealed that there were 174 cases among 187 attendees at a local funeral earlier in the day. Most cases had eaten served sandwiches containing egg products that had undergone severe time-temperature abuse. While no causal agents were identified, the epidemiology and clinical presentation is compatible with foodborne toxins, most likely enterotoxins of either Staphylococcus aureus or Bacillus cereus. Mitigation measures undertaken by public health centered on education of food preparers and the general public regarding safe food preparation practices. This large outbreak serves to remind us that, while there are simple and highly effective measures to prevent such foodborne disease outbreaks, we in the public health sector have a duty to improve the community's knowledge and understanding of these measures.

Detection of pathogens in the food chain is limited mainly to bacteria, and the globalization of the food industry enables international viral foodborne outbreaks to occur. Outbreaks from 2002 through 2006 recorded in a European norovirus surveillance database were investigated for virologic and epidemiologic indicators of food relatedness. The resulting validated multivariate logistic regression model comparing foodborne (n = 224) and person-to-person (n = 654) outbreaks was used to create a practical web-based tool that can be limited to epidemiologic parameters for nongenotyping countries. Non-genogroup-II.4 outbreaks, higher numbers of cases, and outbreaks in restaurants or households characterized (sensitivity = 0.80, specificity = 0.86) foodborne outbreaks and reduced the percentage of outbreaks requiring source-tracing to 31%. The selection tool enabled prospectively focused follow-up. Use of this tool is likely to improve data quality and strain typing in current surveillance systems, which is necessary for identification of potential international foodborne outbreaks.

Nowadays, viruses of foodborne origin such as norovirus and hepatitis A are considered major causes of foodborne gastrointestinal illness with widespread distribution worldwide. A number of foodborne outbreaks associated with food products of animal and non-animal origins, which often involve multiple cases of variety of food streams, have been reported. Although several viruses, including rotavirus, adenovirus, astrovirus, parvovirus, and other enteroviruses, significantly contribute to incidence of gastrointestinal diseases, systematic information on the role of food in transmitting such viruses is limited. Most of the outbreak cases caused by infected food handlers were the source of 53% of total outbreaks. Therefore, prevention and hygiene measures to reduce the frequency of foodborne virus outbreaks should focus on food workers and production site of food products. Pivotal strategies, such as proper investigation, surveillance, and reports on foodborne viral illnesses, are needed in order to develop more accurate measures to detect the presence and pathogenesis of viral infection with detailed descriptions. Moreover, molecular epidemiology and surveillance of food samples may help analysis of public health hazards associated with exposure to foodborne viruses. In this present review, we discuss different aspects of foodborne viral contamination and its impact on human health. This review also aims to improve understanding of foodborne viral infections as major causes of human illness as well as provide descriptions of their control and prevention strategies and rapid detection by advanced molecular techniques. Further, a brief description of methods available for the detection of viruses in food and related matrices is provided.

Zoonoses are diseases that are transmitted naturally between animals and humans. The control of food-borne zoonoses within the European Union is a prerequisite for assuring a functional internal market and consequently represents an important item on the political agenda. Unfortunately, until recently, gaining a clear view of the current incidence of food-borne zoonoses and the prevalence of its causative agents has been frustrated by the absence of reliable monitoring and reporting systems. Similarly, it has become clear that, Europe wide, one has witnessed only limited success with regard to the control of important food-borne agents such as Salmonella spp. The European Union has adopted legislation to remedy this situation and to control food-borne zoonoses in primary production. This contribution discusses the incentives for introducing EU Directive 2003/99/EC and EU Regulation No. 2160/2003, summarises their essentials and discusses major ramifications of both pieces of legislation for the prevention of food-borne zoonoses. It is concluded that there is reason for cautious optimism concerning human salmonellosis, while for other food-borne zoonoses there should be a call for action.

Noroviruses are the leading cause of foodborne disease in the United States. Foodborne transmission of norovirus is often associated with contamination of food during preparation by an infected food worker. The U.S. Food and Drug Administration's Food Code provides model food safety regulations for preventing transmission of foodborne disease in restaurants; however, adoption of specific provisions is at the discretion of state and local governments. We analyzed the food service regulations of all 50 states and the District of Columbia (i.e., 51 states) to describe differences in adoption of norovirus-related Food Code provisions into state food service regulations. We then assessed potential correlations between adoption of these regulations and characteristics of foodborne norovirus outbreaks reported to the National Outbreak Reporting System from 2009 through 2014. Of the 51 states assessed, all (100%) required food workers to wash their hands, and 39 (76%) prohibited bare-hand contact with ready-to-eat food. Thirty states (59%) required exclusion of staff with vomiting and diarrhea until 24 h after cessation of symptoms. Provisions requiring a certified food protection manager (CFPM) and a response plan for contamination events (i.e., vomiting) were least commonly adopted; 26 states (51%) required a CFPM, and 8 (16%) required a response plan. Although not statistically significant, states that adopted the provisions prohibiting bare-hand contact (0.45 versus 0.74, P =0.07), requiring a CFPM (0.38 versus 0.75, P =0.09), and excluding ill staff for ≥24 h after symptom resolution (0.44 versus 0.73, P =0.24) each reported fewer foodborne norovirus outbreaks per million person-years than did those states without these provisions. Adoption and compliance with federal recommended food service regulations may decrease the incidence of foodborne norovirus outbreaks.

2016-02-01

This study systemically analyzed data on the prevalence of foodborne pathogens and foodborne disease outbreaks to identify the priorities of foodborne infection risk management in Korea. Multiple correspondence analysis was applied to three variables: origin of food source, phase of food supply chain, and 12 pathogens using 358 cases from 76 original papers and official reports published in 1998-2012. In addition, correspondence analysis of two variables--place and pathogen--was conducted based on epidemiological data of 2357 foodborne outbreaks in 2002-2011 provided by the Korean Ministry of Food and Drug Safety. The results of this study revealed three distinct areas of food monitoring: (1) livestock-derived raw food contaminated with Campylobacter spp., pathogenic Escherichia coli, Salmonella spp., and Listeria monocytogenes; (2) multi-ingredient and ready-to-eat food related to Staphylococcus aureus; and (3) water associated with norovirus. Our findings emphasize the need to track the sources and contamination pathways of foodborne pathogens for more effective risk management.

A community trial on heat-related-illness-prevention behaviors and knowledge for people aged between 65 and 84 years was conducted in Nagasaki, Japan. Five hundred eight subjects were selected randomly from three groups: heat health warning (HHW, HHW and water delivery (HHW+W, and control groups. Baseline and follow-up questionnaires were conducted in June and September 2012, respectively. Of the 1524 selected subjects, the 1072 that completed both questionnaires were analyzed. The HHW+W group showed improvements in nighttime AC use (p = 0.047, water intake (p = 0.003, cooling body (p = 0.002 and reduced activities in heat (p = 0.047 compared with the control, while the HHW group improved hat or parasol use (p = 0.008. An additional effect of household water delivery was observed in water intake (p = 0.067 and cooling body (p = 0.095 behaviors. HHW and household bottled water delivery improved heat-related-illness-prevention behaviors. The results indicate that home water delivery in addition to a HHW may be needed to raise awareness of the elderly.

To describe surrogate decision makers' (SDMs) perspectives on preventable breakdowns in care among critically ill patients. We screened 70 SDMs of critically ill patients for those who identified a preventable breakdown in care, defined as an event where the SDM believes something "went wrong", that could have been prevented, and resulted in harm. In-depth interviews were conducted with SDMs who identified an eligible event. 32 of 70 participants (46%) identified at least one preventable breakdown in care, with a total of 75 discrete events. Types of breakdowns involved medical care (n=52), communication (n=59), and both (n=40). Four additional breakdowns were related to problems with SDM bedside access to the patient. Adverse consequences of breakdowns included physical harm, need for additional medical care, emotional distress, pain, suffering, loss of trust, life disruption, impaired decision making, and financial expense. 28 of 32 SDMs raised their concerns with clinicians, yet only 25% were satisfactorily addressed. SDMs of critically ill patients frequently identify preventable breakdowns in care which result in harm. An in-depth understanding of the types of events SDMs find problematic and the associated harms is an important step towards improving the safety and patient-centeredness of healthcare.

To determine whether patients with serious mental illness (SMI) are receiving preventive care for cardiovascular disease at the same rate as those without SMI in an interprofessional practice with a mandate to care for persons with barriers to access to the health care system. Quality improvement exercise using a case-matched retrospective chart review. Somerset West Community Health Centre in downtown Ottawa, Ont. All patients with SMI were adult, current primary care patients from the Somerset West Community Health Centre with a recorded diagnosis of SMI (bipolar affective disorder, schizophrenia, or other psychosis) during the 2-year period from June 1, 2013, to May 31, 2015. Two control patients (current primary care patients without SMI and matched for age and sex) were randomly chosen for each patient with SMI. They had at least 1 record in their electronic chart during the 2-year study period of measurement of blood pressure, weight, body mass index, smoking status, lipid screening results, or diabetes screening results. Prevention score was calculated as the number of preventive tests documented out of the possible 6. Secondary measures included age, sex, comorbidities (diabetes, hypertension, or hyperlipidemia), mental illness diagnosis, involvement of a psychiatrist, and involvement of a mental health case worker. Patients with SMI had higher rates of diabetes, hypertension, and dyslipidemia. Screening rates for the 6 outcome measures were very similar between patients with and without SMI. Patients with SMI who were under the care of a psychiatrist or who had a case worker had more complete screening results than those who had neither provider. As expected, patients with SMI had higher rates of metabolic comorbidities than control patients had. Screening rates for cardiovascular risk factors were similar in the 2 groups. Involvement of mental health case workers and psychiatrists in the patients' care might be linked to more complete preventive screening

Polypharmacy and Delirium in Critically Ill Older Adults: Recognition and Prevention.

Science.gov (United States)

Garpestad, Erik; Devlin, John W

2017-05-01

Among older adults, polypharmacy is a sequelae of admission to the intensive care unit and is associated with increased medication-associated adverse events, drug interactions, and health care costs. Delirium is prevalent in critically ill geriatric patients and medications remain an underappreciated modifiable risk for delirium in this setting. This article reviews the literature on polypharmacy and delirium, with a focus on highlighting the relationships between polypharmacy and delirium in critically ill, older adults. Discussed are clinician strategies on how to recognize and reduce medication-associated delirium and recommendations that help prevent polypharmacy when interventions to reduce the burden of delirium in this vulnerable population are being formulated.

Bacterial food-borne pathogens in Indian food

Bandekar, J.R.

2015-01-01

Food technology and food processing techniques have made tremendous advances in preservation of food and ensuring safety of food by killing food-borne pathogens. In addition to old techniques such as pasteurization, canning, dehydration, fermentation and salting, a number of new techniques such as radiation processing, high pressure technology and pulsed electric field technology are being applied for preservation of food and to ensure food safety. Total Quality Management (TQM) concepts have been developed to take care of food safety from farm to table. Hazard Analysis at Critical Control Points (HACCP) is being applied for mass scale production of food to make food free from pathogens. Despite these advances, food-borne diseases have become one of the most widespread public health problems in the world. About two thirds of all the outbreaks are traced to microbial contaminated food. According to World Health Organization (WHO) estimates, food-borne and waterborne diarrhoeal diseases kill an estimated 2 million people annually, including many children. Food safety is a major concern not only for developing countries but also for the developed countries. A number of factors such as emergence of new food-borne pathogens, development of drug resistance in pathogens, changing life style, globalization of the food supply etc. are responsible for the continuous persistence of food-borne diseases. The food-borne disease outbreaks due to E. coli O157:H7, Listeria monocytogenes, Salmonella and Campylobacter, are responsible for recall of many foods resulting in heavy losses to food industry. Due to consumer demand, a number of Ready-To-Eat (RTE) minimally processed foods are increasingly marketed; however, there is increased risk of foodborne diseases with these products. Food Technology Division of Bhabha Atomic Research Centre, Mumbai, has been working on food-borne bacterial pathogens particularly Salmonella, Campylobacter, Listeria monocytogenes, Vibrio and Aeromonasf

Chen, Jun; Fan, Chaogang

2016-07-01

Nutritional support is an important means to treat the patients with chronic critical illness for commonly associated malnutrition. Refeeding syndrome is a serious complication during the process, mainly manifested as severe electrolyte with hypophosphataemia being the most common. Refeeding syndrome is not uncommon but it is often ignored. In our future clinical work, we need to recognize this chinical situation and use preventative and treatment measures. According to NICE clinical nutrition guideline, we discussed the risk factors, treatment methods and preventive measures of refeeding syndrome in patients with chronic critical illness. We argued that for patients with high risk refeeding syndrome, nutritional support treatment should be initially low calorie and slowly increased to complete requirement. Circulation capacity should be recovered, fluid balance must be closely monitored and supplement of vitamins, microelement, electrolytes should be noted. After the emergence of refeeding syndrome, we should reduce or even stop the calorie intake, give an active treatment for electrolyte disorder, provide vitamin B, and maintain the functions of multiple organs.

Food-borne yeasts, excluding yeasts used as starter cultures, are commonly considered as food spoilage microorganisms. However, the incidence of non-C. albicans Candida (NCAC) infections has increased considerably over the past two decades. Although 15 Candida species are frequently identified as pathogens, a threat to human from food-borne Candida is poorly recognized. In the present study food-borne NCAC were characterized for the virulence factors, known to be associated with yeast pathogenicity. All food-borne strains in planktonic forms and 89% in biofilm structures represented biotypes established for C. albicans, and 61% demonstrated hemolytic activity. 56-94% of food-borne isolates formed biofilms on glass and biomaterials at a level comparable to clinical C. albicans. Nine out of eighteen tested food-borne NCAC strains (C. krusei, C. lusitaniae, C. famata, C. colliculosa, C. parapsilosis, C. tropicalis) showed similarity to clinical C. albicans in terms of their biotypes and the tested virulence factors, allocating them in a group of risk of potential pathogens. However, their capacity to grow at 37 °C seems to be the preliminary criterion in the study of potential virulence of food-borne yeasts. Copyright © 2018 Elsevier B.V. All rights reserved.

Variations in the radiation sensitivity of foodborne pathogens associated with complex ready-to-eat food products

Sommers, Christopher H.; Boyd, Glenn

2006-07-01

Foodborne illness outbreaks and product recalls are occasionally associated with ready-to-eat (RTE) sandwiches and other "heat and eat" multi-component RTE products. Ionizing radiation can inactivate foodborne pathogens on meat and poultry, fruits and vegetables, seafood, and RTE meat products. However, less data are available on the ability of low-dose ionizing radiation, doses under 5 kGy typically used for pasteurization purposes, to inactivate pathogenic bacteria on complex multi-component food products. In this study, the efficacy of ionizing radiation to inactivate Salmonella spp., Listeria monocytogenes, Staphylococcus aureus, Escherichia coli O157:H7, and Yersinia enterocolitica on RTE foods including a "frankfurter on a roll", a "beef cheeseburger on a bun" and a "vegetarian cheeseburger on a bun" was investigated. The average D-10 values, the radiation dose needed to inactivate 1 log 10 of pathogen, by bacterium species, were 0.61, 0.54, 0.47, 0.36 and 0.15 kGy for Salmonella spp., S. aureus, L. monocytogenes, E. coli O157:H7, and Y. enterocolitica, respectively when inoculated onto the three product types. These results indicate that irradiation may be an effective means for inactivating common foodborne pathogens including Salmonella spp, S. aureus, L. monocytogenes, E. coli O157:H7 and Y. enterocolitica in complex RTE food products such as 'heat and eat" sandwich products.

toxoplasmosis with 825,000 DALYs (95% UI 561,000-1.26 million resulted in the highest burdens in terms of DALYs, mainly due to years lived with disability. Foodborne enteric protozoa, reported elsewhere, resulted in an additional 67.2 million illnesses or 492,000 DALYs. Major limitations of our study include often substantial data gaps that had to be filled by imputation and suffer from the uncertainties that surround such models. Due to resource limitations it was also not possible to consider all potentially foodborne parasites (for example Trypanosoma cruzi.Parasites are frequently transmitted to humans through contaminated food. These estimates represent an important step forward in understanding the impact of foodborne diseases globally and regionally. The disease burden due to most foodborne parasites is highly focal and results in significant morbidity and mortality among vulnerable populations.

Categorizing food-related illness: Have we got it right?

Science.gov (United States)

Manning, Louise

2017-06-13

Since the 1950s food safety hazards have been categorized simply as (micro) biological, chemical or physical hazards with no clear differentiation between those that cause acute and chronic harm. Indeed international risk assessment methods, including hazard analysis critical control point (HACCP) use these criteria. However, the spectrum of food related illness continues to grow now encompassing food allergy and intolerance, obesity, type 2 diabetes, stroke, heart disease, cancer as well as food poisoning, foodborne illness and food contamination. Therefore over a half-century later is this the time to redefine the spectrum of what constitutes food related illness? This paper considers whether such "redefinition" of food related intoxicating and infectious agents would provide more targeted policy instruments and lead to better risk assessment and thus mitigation of such risk within the food supply chain.

Understanding consumers' food safety practices and knowledge supports food safety education for the prevention of foodborne illness. The objective of this study was to describe Canadian consumer food safety practices and knowledge. This study identifies demographic groups for targeted food safety education messaging and establishes a baseline measurement to assess the effectiveness of food safety interventions over time. Questions regarding consumer food safety practices and knowledge were included in a population-based telephone survey, Foodbook, conducted from November 2014 to March 2015. The results were analyzed nationally by age group and by gender. The results showed that approximately 90% of Canadians reported taking the recommended cleaning and separating precautions when handling raw meat to prevent foodborne illness. Only 29% of respondents reported using a food thermometer when cooking any meat, and even fewer (12%) reported using a food thermometer for small cuts of meat such as chicken pieces. The majority (>80%) of Canadians were aware of the foodborne illness risks related to chicken and hamburger, but fewer (poultry.

An important step in research using the Theory of Reasoned Action and Theory of Planned Behavior (TRA/TPB) is conducting an elicitation process to identify topic and population specific cognitions. This study explored HIV risk behaviors in persons with mental illnesses and introduces findings from focus groups conducted during the development phase of an HIV primary and secondary prevention intervention study. Researchers held four focus groups with persons with mental illnesses focused on HIV risks and condom use. Participants discussed sexual side effects of psychotropic medications as a potential cause of both medication non-adherence and HIV risk behaviors. The intersection of these two issues is specific to this population. We conclude with the recommendation that HIV primary and secondary prevention intervention for persons with mental illnesses must incorporate the promotion of healthy sexuality, including attention to sexual side effects of psychotropic medications.

2016-12-24

Bacterial toxin-mediated foodborne outbreaks, such as those caused by Clostridium perfringens, Staphylococcus aureus and Bacillus cereus, are an important and preventable cause of morbidity and mortality. Due to the short incubation period and duration of illness, these outbreaks are often under-reported. This is the first study to describe the epidemiology of bacterial toxin-mediated outbreaks in Australia. Using data collected between 2001 and 2013, we identify high risk groups and risk factors to inform prevention measures. Descriptive analyses of confirmed bacterial toxin-mediated outbreaks between 2001 and 2013 were undertaken using data extracted from the OzFoodNet Outbreak Register, a database of all outbreaks of gastrointestinal disease investigated by public health authorities in Australia. A total of 107 laboratory confirmed bacterial toxin-mediated outbreaks were reported between 2001 and 2013, affecting 2,219 people, including 47 hospitalisations and 13 deaths. Twelve deaths occurred in residents of aged care facilities. Clostridium perfringens was the most commonly reported aetiological agent (81 outbreaks, 76%). The most commonly reported food preparation settings were commercial food preparation services (51 outbreaks, 48%) and aged care facilities (42 outbreaks, 39%). Bacterial toxin outbreaks were rarely associated with food preparation in the home (2 outbreaks, 2%). In all outbreaks, the primary factor contributing to the outbreak was inadequate temperature control of the food. Public health efforts aimed at improving storage and handling practices for pre-cooked and re-heated foods, especially in commercial food preparation services and aged care facilities, could help to reduce the magnitude of bacterial toxin outbreaks.

This paper calls for the routine integration of mental health promotion and prevention into UK General Practice in order to reduce the burden of mental and physical disorders and the ensuing pressure on General Practice. The proposals & the resulting document (https://ethicscharity.files.wordpress.com/2015/09/rcgp_keymsg_150925_v5.pdf) arise from an expert 'Think Tank' convened by the London Journal of Primary Care, Educational Trust for Health Improvement through Cognitive Strategies (ETHICS Foundation) and the Royal College of General Practitioners. It makes 12 recommendations for General Practice: (1) Mental health promotion and prevention are too important to wait. (2) Work with your community to map risk factors, resources and assets. (3) Good health care, medicine and best practice are biopsychosocial rather than purely physical. (4) Integrate mental health promotion and prevention into your daily work. (5) Boost resilience in your community through approaches such as community development. (6) Identify people at increased risk of mental disorder for support and screening. (7) Support early intervention for people of all ages with signs of illness. (8) Maintain your biopsychosocial skills. (9) Ensure good communication, interdisciplinary team working and inter-sectoral working with other staff, teams and agencies. (10) Lead by example, taking action to promote the resilience of the general practice workforce. (11) Ensure mental health is appropriately included in the strategic agenda for your 'cluster' of General Practices, at the Clinical Commissioning Groups, and the Health and Wellbeing Board. (12) Be aware of national mental health strategies and localise them, including action to destigmatise mental illness within the context of community development.

Antibacterial Activity and Action Mechanism of the Essential Oil from Enteromorpha linza L. against Foodborne Pathogenic Bacteria

Directory of Open Access Journals (Sweden)

Jayanta Kumar Patra

2016-03-01

Full Text Available Foodborne illness and disease caused by foodborne pathogenic bacteria is continuing to increase day by day and it has become an important topic of concern among various food industries. Many types of synthetic antibacterial agents have been used in food processing and food preservation; however, they are not safe and have resulted in various health-related issues. Therefore, in the present study, essential oil from an edible seaweed, Enteromorpha linza (AEO, was evaluated for its antibacterial activity against foodborne pathogens, along with the mechanism of its antibacterial action. AEO at 25 mg/disc was highly active against Bacillus cereus (12.3–12.7 mm inhibition zone and Staphylococcus aureus (12.7–13.3 mm inhibition zone. The minimum inhibitory concentration and minimum bactericidal concentration values of AEO ranged from 12.5–25 mg/mL. Further investigation of the mechanism of action of AEO revealed its strong impairing effect on the viability of bacterial cells and membrane permeability, as indicated by a significant increase in leakage of 260 nm absorbing materials and K+ ions from the cell membrane and loss of high salt tolerance. Taken together, these data suggest that AEO has the potential for use as an effective antibacterial agent that functions by impairing cell membrane permeability via morphological alternations, resulting in cellular lysis and cell death.

Full Text Available Abstract Background On 4th February 2015, a group of Senior High School students from Fanteakwa district presented to the emergency unit of the district hospital with complaints of abdominal pain, vomiting and diarrhoea. All the students had eaten from a specific food vendor and had neither eaten any other common meal that day nor the previous day. A foodborne disease outbreak was suspected. We investigated to verify the outbreak, determine its magnitude, identify the source and implement control measures. Methods A retrospective cohort study was conducted. We reviewed medical records and interviewed patrons of the food vendor. We collected data on age, sex, signs and symptoms, date of illness onset, date of admission, date of discharge, treatments given and outcome. A case of foodborne disease was any person in the school with abdominal pain, vomiting and or diarrhoea from 4th to 11th February 2015 and had eaten from the food vendor. We conducted active case search to identify more cases. We conducted environmental assessment and collected clinical and food samples for laboratory testing. Descriptive and inferential statistical analyses were performed using Stata 12.0. Results A total of 68 cases were recorded giving overall attack rate of 35.79 % (68/190 with no death. Of these, 51.47 % (35/68 were males. Mean age of case-patients was 17.8 (standard deviation +/-1.62. The index case, a 17-year-old female student ate from the food vendor on 4th February at 9:00 am and fell ill at 3:40 pm later that day. Compared to those who ate other food items, students who drank water from container at the canteen were more likely to develop foodborne disease at statistically significant levels [RR = 2.6, 95 % CI = (2.11–3.15]. Clostridium perfringens (C. perfringens and Salmonella species (Salmonella spp were isolated from water and stew respectively. Clinical features of case-patients were compatible with both organisms.

Exercise and Life-Satisfactory-Fitness: Complementary Strategies in the Prevention and Rehabilitation of Illnesses

Directory of Open Access Journals (Sweden)

Christiane Jennen

2004-01-01

Full Text Available Moderate training of an endurance nature, but also other exercise activities, not only has a preventive effect on various illnesses and pre-illness states such as the metabolic syndrome and cancer, but is also effective in treating patients in the rehabilitation phase after illness, e.g. cardiovascular or cancer. Our investigation demonstrates that even low level physical activity has a very good preventive effect too, which is enhanced when it is accompanied by mental activity and psychological well-being. In total, we investigated 13 000 people on the basis of socio-economic panel polls with respect to life contentment, health status and leisure-time activities. Life contentment is positively linked to contentment with labor, which seems to be an essential aspect with regard to the increasing number of unemployed people in Europe. The second important factor is health-promoting activities during leisure time. Exercise, especially, has a significant influence on life satisfaction as a feeling of physical fitness feeling is regarded as synonymous with good health. The results underline the psycho-neuroimmunological network, which stabilizes our health and shows that different activities in older adults have a significant effect on the aging process and age-related illnesses. Besides the various activities that are important in this arena, namely muscle and mental mobility (‘brawn and brain’, a third component must be taken into consideration: life contentment in the form of a successful retrospective view and a positive outlook, embedded in a psychosocial family environment (‘brood’ and integrated in a stress-free biotope, where life does make sense. Alternative and complementary strategies should be considered in light of these three aspects when we think about additional anti-inflammatory strategies in preventing diseases or treating them and their relapses.

This study evaluated the proportion of food samples, examined by the Italian Istituti Zooprofilattici Sperimentali (Experimental Zooprophylactic Institutes) in the years 2000-2005, positive for Campylobacter and Listeria. A correlation was found between food samples found positive for Listeria in the years 2002-2005 and the number of hospitalisations for Listeria illness in the same years (as reported in hospital discharge abstract forms). This confirms that attention should be given in the evaluation of phenomena known to be under reported and for which data are collected and analysed by different methods.

Foodborne illness outbreaks and product recalls are occasionally associated with ready-to-eat (RTE) sandwiches and other 'heat and eat' multi-component RTE products. Ionizing radiation can inactivate foodborne pathogens on meat and poultry, fruits and vegetables, seafood, and RTE meat products. However, less data are available on the ability of low-dose ionizing radiation, doses under 5 kGy typically used for pasteurization purposes, to inactivate pathogenic bacteria on complex multi-component food products. In this study, the efficacy of ionizing radiation to inactivate Salmonella spp., Listeria monocytogenes, Staphylococcus aureus, Escherichia coli O157:H7, and Yersinia enterocolitica on RTE foods including a 'frankfurter on a roll', a 'beef cheeseburger on a bun' and a 'vegetarian cheeseburger on a bun' was investigated. The average D-10 values, the radiation dose needed to inactivate 1 log{sub 1} of pathogen, by bacterium species, were 0.61, 0.54, 0.47, 0.36 and 0.15 kGy for Salmonella spp., S. aureus, L. monocytogenes, E. coli O157:H7, and Y. enterocolitica, respectively when inoculated onto the three product types. These results indicate that irradiation may be an effective means for inactivating common foodborne pathogens including Salmonella spp, S. aureus, L. monocytogenes, E. coli O157:H7 and Y. enterocolitica in complex RTE food products such as 'heat and eat' sandwich products.

Full Text Available Thirty-five strains of lactic acid bacteria were isolated from artisanal raw milk cheese, presumptively identified and tested against one dairy Escherichia coli strain. Six lactobacilli, exhibiting antagonistic activity, were identified at the species level and their action was evaluated against four strains of Gram-foodborne pathogens (Escherichia coli O26, Escherichia coli O157:H7, Salmonella spp. 1023, and Salmonella Typhimurium and the control strain Escherichia coli ATCC 45922. The antagonistic activity was determined by spot method and the inhibition zones were measured by Autodesk AutoCAD 2007. Three strains, all Lactobacillus paracasei, were active against all the pathogens; the other strains, all Lactobacillus plantarum, showed antagonistic activity against some pathogens. This study highlights the intense and different antagonistic activity induced by lactobacilli against various foodborne pathogens thus demonstrating that using selected lactic acid bacteria strains as adjunct cultures could be an effective strategy to prevent the development of foodborne pathogens in artisanal raw milk cheeses, and thus improving their safety.

As part of the National Action Plan for Non-communicable Disease Prevention, Control and Health Promotion in Pakistan (NAP-NCD), mental illnesses have been grouped alongside non-communicable diseases (NCD) within a combined strategic framework in order to synchronize public health actions. The systematic approach for mental illnesses is centred on safeguarding the rights of the mentally ill, reducing stigma and discrimination, and de-institutionalisation and rehabilitation of the mentally ill in the community outlining roles of healthcare providers, the community, legislators and policy makers. The approach has implications for support functions in a number of areas including policy building, manpower and material development and research. Priority action areas for mental health as part of NAP-NCD include the integration of surveillance of mental illnesses in a comprehensive population-based NCD surveillance system; creating awareness about mental health as part of an integrated NCD behavioural change communication strategy; integration of mental health with primary healthcare; the development of sustainable public health infrastructure to support community mental health initiatives; building capacity of the health system in support of prevention and control activities; effective implementation of existing legislation and harmonizing working relationships with law enforcing agencies. NAP-NCD also stresses on the need to integrate mental health into health services as part of a sustainable and integrated medical education programme for all categories of healthcare providers and the availability of essential psychotropic drugs at all healthcare levels. It lays emphasis on protecting the interests of special groups such as prisoners, refugees and displaced persons, women, children and individuals with disabilities. Furthermore, it promotes need-based research for contemporary mental health issues.

Hiroshi Fukushima

2009-01-01

Full Text Available A set of four duplex SYBR Green I PCR (SG-PCR assay combined with DNA extraction using QIAamp DNA Stool Mini kit was evaluated for the detection of foodborne bacteria from 21 foodborne outbreaks. The causative pathogens were detected in almost all cases in 2 hours or less. The first run was for the detection of 8 main foodborne pathogens in 5 stool specimens within 2 hours and the second run was for the detection of other unusual suspect pathogens within a further 45 minutes. After 2 to 4 days, the causative agents were isolated and identified. The results proved that for comprehensive and rapid molecular diagnosis in foodborne outbreaks, Duplex SG-PCR assay is not only very useful, but is also economically viable for one-step differentiation of causative pathogens in fecal specimens obtained from symptomatic patients. This then allows for effective diagnosis and management of foodborne outbreaks.

Salmonella is the most common bacterial cause of foodborne outbreaks in the United States. Starting in June 2007, investigation of a cluster of Salmonella Montevideo cases with indistinguishable pulsed-field gel electrophoresis (PFGE) patterns resulted in the identification of an outbreak associated with contact with chickens purchased from a single hatchery. Nine Minnesota cases from May through August 2007 were part of this outbreak. Cases with the outbreak PFGE pattern of Salmonella Montevideo continued to occur in Minnesota after August, but none of these cases reported chicken contact. The majority of these cases resided in the same town in rural Minnesota. Routine interviews revealed that all cases from these counties purchased groceries from the same local grocery store, with two specifically reporting consuming items from the grocery store delicatessen in the week before illness. As a result, an investigation into the delicatessen was initiated. Illness histories and stool samples were collected from all delicatessen employees, and food and environmental samples were collected. None of the employees reported experiencing recent gastrointestinal symptoms, but the outbreak PFGE subtype of Salmonella Montevideo was identified from stool from two food workers. Food and environmental samples collected tested negative for Salmonella. One of the positive employees reported having chickens at home, but the animals did not test positive for Salmonella. The positive food workers were excluded from work until they had two consecutive negative stool cultures for Salmonella. There was no evidence of ongoing transmission thereafter. This was an outbreak of Salmonella Montevideo infections that began as an animal-contact-associated outbreak which subsequently resulted in a foodborne outbreak associated with infected food workers. These outbreaks illustrate the complex epidemiology of salmonellosis.

Rapid detection of foodborne pathogens at an early stage is imperative for preventing the outbreak of foodborne diseases, known as serious threats to human health. Conventional bacterial culturing methods for foodborne pathogen detection are time consuming, laborious, and with poor pathogen diagnosis competences. This has prompted researchers to call the current status of detection approaches into question and leverage new technologies for superior pathogen sensing outcomes. Novel strategies mainly rely on incorporating all the steps from sample preparation to detection in miniaturized devices for online monitoring of pathogens with high accuracy and sensitivity in a time-saving and cost effective manner. Lab on chip is a blooming area in diagnosis, which exploits different mechanical and biological techniques to detect very low concentrations of pathogens in food samples. This is achieved through streamlining the sample handling and concentrating procedures, which will subsequently reduce human errors and enhance the accuracy of the sensing methods. Integration of sample preparation techniques into these devices can effectively minimize the impact of complex food matrix on pathogen diagnosis and improve the limit of detections. Integration of pathogen capturing bio-receptors on microfluidic devices is a crucial step, which can facilitate recognition abilities in harsh chemical and physical conditions, offering a great commercial benefit to the food-manufacturing sector. This article reviews recent advances in current state-of-the-art of sample preparation and concentration from food matrices with focus on bacterial capturing methods and sensing technologies, along with their advantages and limitations when integrated into microfluidic devices for online rapid detection of pathogens in foods and food production line.

2017-12-01

Full Text Available Background: Cross-contamination of foodborne pathogens from undercooked poultry meat to ready-to-eat food has been shown to be responsible for a number of foodborne disease outbreaks. Various studies have indicated that bacterial cross-contamination occurs during food preparation where bacteria present on food contact other surfaces and cause illness. Objectives: This study evaluated the ability of bacteria to survive and cross-contaminate other foods during the preparation of fresh chicken. Salmonella spp. cross-contamination from chicken to cucumber and utensils under various food handling scenarios was determined. Methods: Two scenarios were tested: in scenario 1, cutting board and knife used for cutting chicken without washing step were sampled. In scenario 2, cutting board and knife was washed with tap water separately after cutting chicken, and subsequently used for cutting cucumber. In scenario 1, chicken, cutting board, knife, and hands were sampled, and in scenario 2, cucumber was tested. Fluorescent in situ hybridization (FISH method, using published Salmonella specific gene probes was used for Salmonella detection in samples taken from cross-contamination scenarios. A culture-based detection by Hektoen enteric agar was used for the confirmation of Salmonella species. Results: All the samples analyzed were found to be positive for Salmonella spp. with different contamination levels. These results were further confirmed by culture based method. In scenario 1, Salmonella spp. was detected by Sal-1 and Salm-63 oligonucleotide probes in all four samples (chicken, cutting board, knife and hands. A high contamination level was observed in chicken samples in comparison to samples collected from cutting board, knife and hands. In scenario 2, Salmonella spp. was detected by Sal-1 and Salm-63 oligonucleotide probes in the cucumber with very low contamination level. Salmonella Enterica was also detected by Sal-3 and Sapath-3 in both scenarios but

Children of psychiatrically ill parents up to now have hardly been perceived as a risk group. In order to prevent these children form becoming psychiatrically ill the practice for art-therapy and psychotherapy and the social psychiatric service of the city of Hilden have developed a programme for parents having children under 18 years of age in which at least one parent suffers from endogenous psychosis or severe personality disorder. The two initiators of the KIPKEL project describe the experiences they had during the preparatory phase and while securing the financial basis and building up solid structures of cooperation. The conceptual basis of the project and problems of practical realization are presented. Finally an example of a family who participated in the programme is given. It illustrates the complex arrangement of interpersonal relationship and the course of the carework.

The aim of the current explorative study is to define and test a process for the valuation of the benefits associated with the prevention of non-fatal work-related accidents and ill health. A relativities approach is adopted, and monetary values for the prevention of three forms of work-related illness are estimated. The approach involves describing relevant attributes of alternative events (accidents or occurrences of ill health), their causes, the characteristics of the relevant working population, and the number of events that are avoidable, and asking respondents to make pair wise choices between alternatives options for prevention. Indirect monetary valuations are obtained against a peg event for which a reliable valuation exists (road deaths).A series of discussion groups were held to identify relevant factors affecting potential valuations and to test the presentation of information. The predicted magnitude of responses for three-case study events (and road deaths) was estimated in a pilot study. These preliminary stages informed the final survey instrument that described five attributes in addition to a statement of the event and occupation, and the likely intervention effect, which was administered by post. Based on a small sample, the results show that virtually all respondents passed the inserted consistency test. The median respondent altered their choice according to the number of events avoided for all three comparisons, such that the estimated valuations appear sensible. Potential amendments are suggested, but the general relativities approach warrants further investigation for the valuation of non-fatal work-related accidents and ill health.

Everyday and Exotic Foodborne Parasites

Directory of Open Access Journals (Sweden)

Marilyn B Lee

2000-01-01

Full Text Available Everyday foodborne parasites, which are endemic in Canada, include the protozoans Entamoeba histolytica, Giardia lamblia and Cryptosporidium parvum. However, these parasites are most frequently acquired through unfiltered drinking water, homosexual activity or close personal contact such as in daycare centres and occasionally via a food vehicle. It is likely that many foodborne outbreaks from these protozoa go undetected. Transmission of helminth infections, such as tapeworms, is rare in Canada because of effective sewage treatment. However, a common foodborne parasite of significance is Toxoplasma gondii. Although infection can be acquired from accidental ingestion of oocysts from cat feces, infection can also result from consumption of tissue cysts in undercooked meat, such as pork or lamb. Congenital transmission poses an immense financial burden, costing Canada an estimated $240 million annually. Also of concern is toxoplasmosis in AIDS patients, which may lead to toxoplasmosis encephalitis, the second most common AIDS-related opportunistic infection of the central nervous system. Exotic parasites (ie, those acquired from abroad or from imported food are of growing concern because more Canadians are travelling and the number of Canada?s trading partners is increasing. Since 1996, over 3000 cases of Cyclospora infection reported in the United States and Canada were epidemiologically associated with importation of Guatemalan raspberries. Unlike toxoplasmosis, where strategies for control largely rest with individual practices, control of cyclosporiasis rests with government policy, which should prohibit the importation of foods at high risk.

To assess food safety practices, food shopping preferences, and eating behaviors of people diagnosed with Salmonella or Campylobacter infection in the warm seasons, and to identify socioeconomic factors associated with behavior and practices. A cross-sectional survey was conducted among Salmonella and Campylobacter cases with onset of illness from January 1 to March 31, 2013. Multivariable logistic regression analyses examined relationships between socioeconomic position and food safety knowledge and practices, shopping and food preferences, and preferences, perceptions, and knowledge about food safety information on warm days. Respondents in our study engaged in unsafe personal and food hygiene practices. They also carried out unsafe food preparation practices, and had poor knowledge of foods associated with an increased risk of foodborne illness. Socioeconomic position did not influence food safety practices. We found that people's reported eating behaviors and food preferences were influenced by warm weather. Our study has explored preferences and practices related to food safety in the warm season months. This is important given that warmer ambient temperatures are projected to rise, both globally and in Australia, and will have a substantial effect on the burden of infectious gastroenteritis including foodborne disease. Our results provide information about modifiable behaviors for the prevention of foodborne illness in the household in the warm weather and the need for information to be disseminated across the general population. An understanding of the knowledge and factors associated with human behavior during warmer weather is critical for public health interventions on foodborne prevention.

The consumption of fruit and vegetables continues to rise in the United States and European Union due to healthy lifestyle recommendations. Meanwhile, the rate of foodborne illness caused by the consumption of these products remains high in both regions, representing a significant public health and financial issue. This study addresses the occurrence of reported foodborne outbreaks associated with fresh fruits and vegetables consumption in the United States and European Union during the period 2004-2012, where data are available. Special attention is paid to those pathogens responsible for these outbreaks, the mechanisms of contamination, and the fresh produce vehicles involved. Norovirus is shown to be responsible for most of the produce-related outbreaks, followed by Salmonella. Norovirus is mainly linked with the consumption of salad in the United States and of berries in the European Union, as demonstrated by the Multiple Correspondence Analysis (MCA). Salmonella was the leading cause of multistate produce outbreaks in the United States and was the pathogen involved in the majority of sprouts-associated outbreaks. As is reflected in the MCA, the pattern of fresh produce outbreaks differed in the United States and European Union by the type of microorganism and the food vehicle involved.

Full Text Available Objective To study the application of DNA microarray technique for screening and identifying multiple food-borne pathogens. Methods The oligonucleotide probes were designed by Clustal X and Oligo 6.0 at the conserved regions of specific genes of multiple food-borne pathogens, and then were validated by bioinformatic analyses. The 5' end of each probe was modified by amino-group and 10 Poly-T, and the optimized probes were synthesized and spotted on aldehyde-coated slides. The bacteria DNA template incubated with Klenow enzyme was amplified by arbitrarily primed PCR, and PCR products incorporated into Aminoallyl-dUTP were coupled with fluorescent dye. After hybridization of the purified PCR products with DNA microarray, the hybridization image and fluorescence intensity analysis was acquired by ScanArray and GenePix Pro 5.1 software. A series of detection conditions such as arbitrarily primed PCR and microarray hybridization were optimized. The specificity of this approach was evaluated by 16 different bacteria DNA, and the sensitivity and reproducibility were verified by 4 food-borne pathogens DNA. The samples of multiple bacteria DNA and simulated water samples of Shigella dysenteriae were detected. Results Nine different food-borne bacteria were successfully discriminated under the same condition. The sensitivity of genomic DNA was 102 －103pg/ μl, and the coefficient of variation (CV of the reproducibility of assay was less than 15%. The corresponding specific hybridization maps of the multiple bacteria DNA samples were obtained, and the detection limit of simulated water sample of Shigella dysenteriae was 3.54×105cfu/ml. Conclusions The DNA microarray detection system based on arbitrarily primed PCR can be employed for effective detection of multiple food-borne pathogens, and this assay may offer a new method for high-throughput platform for detecting bacteria.

Information regarding the relationship between the incidence of foodborne diseases (FBD) and climatic factors is useful in designing preventive strategies for FBD based on anticipated future climate change. To better predict the effect of climate change on foodborne pathogens, the present study investigated the combined influence of multiple climatic factors on bacterial FBD incidence in South Korea. During 2011-2015, the relationships between 8 climatic factors and the incidences of 13 bacterial FBD, were determined based on inpatient stays, on a monthly basis using the Pearson correlation analyses, multicollinearity tests, principal component analysis (PCA), and the seasonal autoregressive integrated moving average (SARIMA) modeling. Of the 8 climatic variables, the combination of temperature, relative humidity, precipitation, insolation, and cloudiness was significantly associated with salmonellosis (Pclimatic factors. These findings indicate that the relationships between multiple climatic factors and bacterial FBD incidence can be valuable for the development of prediction models for future patterns of diseases in response to changes in climate.

Viator, Catherine; Blitstein, Jonathan; Brophy, Jenna E; Fraser, Angela

2015-02-01

This study reviews the current literature on behavioral and environmental food safety interventions conducted in commercial and institutional food service settings. A systematic search of the published literature yielded 268 candidate articles, from which a set of 23 articles reporting intervention outcomes was retained for evaluation. A categorization of measured outcomes is reported; studies addressed multiple outcomes ranging from knowledge, attitudes, and behavior of personal hygiene and food safety to management practices and disease rates and outbreaks. This study also investigates the quality of reported research methods used to evaluate the effectiveness of the interventions, using a nine-point quality index adapted by the authors. The observed scores suggest that there are opportunities to improve the design and reporting of research in the field of foodborne disease prevention as it applies to food safety interventions that target the food service industry. The aim is to aid researchers in this area to design higher quality studies and to produce clearer and more useful reports of their research. In turn, this can help to create a more complete evidence base that can be used to continually improve interventions in this domain.

The exposure of workers to hot environments is expected to increase as a result of climate change. In order to prevent heat-related illness, it is recommended that workers take breaks during working hours. However, this would lead to reductions in worktime and labor productivity. In this study, we estimate the economic cost of heat-related illness prevention through worker breaks associated with climate change under a wide range of climatic and socioeconomic conditions. We calculate the worktime reduction based on the recommendation of work/rest ratio and the estimated future wet bulb glove temperature, which is an index of heat stresses. Corresponding GDP losses (cost of heat-related illness prevention through worker breaks) are estimated using a computable general equilibrium model throughout this century. Under the highest emission scenario, GDP losses in 2100 will range from 2.6 to 4.0% compared to the current climate conditions. On the other hand, GDP losses will be less than 0.5% if the 2.0 °C goal is achieved. The benefit of climate-change mitigation for avoiding worktime loss is comparable to the cost of mitigation (cost of the greenhouse gas emission reduction) under the 2.0 °C goal. The relationship between the cost of heat-related illness prevention through worker breaks and global average temperature rise is approximately linear, and the difference in economic loss between the 1.5 °C goal and the 2.0 °C goal is expected to be approximately 0.3% of global GDP in 2100. Although climate mitigation and socioeconomic development can limit the vulnerable regions and sectors, particularly in developing countries, outdoor work is still expected to be affected. The effectiveness of some adaptation measures such as additional installation of air conditioning devices or shifting the time of day for working are also suggested. In order to reduce the economic impacts, adaptation measures should also be implemented as well as pursing ambitious climate change

Full Text Available The aim of this work is to describe the results of an official control project forwarded on the evaluation of prevention of foodborne viruses diseases. The authors describe the real diffusion of noroviruses and sapoviruses including their general features. The Official control carried out is focused on the valuation of specific prevention measures put in place by food business operators in order to avoid fecal-oral contaminations. Assessment on procedures on GMP, GHP and HACCP were followed by a specific valuation of food handlers training based on a questionnaire .The results show that in small and less developed food industries there is a lack in considering fecal-oral route contaminations and an important need of correct training aimed principally at improving knowledge of Good Hygienic Practices and contamination of food.

Individuals with mental illnesses have higher morbidity rates and reduced life expectancy compared to the general population. Understanding how patients and providers perceive the need for prevention, as well as the barriers and beliefs that may contribute to insufficient care, are important for improving service delivery tailored to this population. Cross-sectional; mixed methods. An integrated health system and a network of federally qualified health centers and safety net clinics. Interviews (n = 30) and surveys (n = 249) with primary care providers. Interviews (n = 158) and surveys (n = 160) with patients diagnosed with schizophrenia, bipolar, anxiety, or major depressive disorders. Semi-structured interviews and surveys. Thematic analysis for qualitative data; frequencies for quantitative data. More than half (n = 131, 53%) of clinicians believed patients with mental illnesses care less about preventive care than the general population, yet 88% (n = 139) of patients reported interest in improving health. Most providers (n = 216, 88%) lacked confidence that patients with mental illnesses would follow preventive recommendations; 82% (n = 129) of patients reported they would try to change lifestyles if their doctor recommended. Clinicians explained that their perception of patients' chaotic lives and lack of interest in preventive care contributed to their fatalistic attitudes on care delivery to this population. Clinicians and patients agreed on substantial need for additional support for behavior changes. Clinicians reported providing informational support by keeping messages simple; patients reported a desire for more detailed information on reasons to complete preventive care. Patients also detailed the need for assistive and tangible support to manage behavioral health changes. Our results suggest a few clinical changes could help patients complete preventive care recommendations and improve health behaviors: improving clinician-patient collaboration on

'Old' and 'new' institutions for persons with mental illness: treatment, punishment or preventive confinement?

Science.gov (United States)

Gostin, Lawrence O

2008-09-01

Despite countless promises for a better life by national commissions, governments and the international community, there has evolved a vicious cycle of neglect, abandonment, indignity, cruel and inhuman treatment, and punishment of persons with mental illness. This shameful history of benign, and sometimes malignant, neglect of persons with mental illness is well understood, with the deep stigma and unredressed discrimination, the deplorable living conditions, and the physical and social barriers preventing their integration and full participation in society. The maltreatment of this vulnerable population has been reinforced by the hurtful stereotypes of incompetency and dangerousness. The belief that persons with mental illness are uniformly dangerous is an equally harmful myth. It provides policy makers with an ostensible justification to exercise control over persons with mental illness, even if they have not committed a violent offence. However, research demonstrates that the class of persons with most mental illnesses is no more dangerous than other populations, and that the vast majority of violence is committed by persons without mental illness. This article will show how this vulnerable population has been unconscionably treated. First, the gross violations of human rights that have occurred, and continue to occur, in 'old' psychiatric institutions will be examined. The deinstitutionalization movement, however, resulted in new places of confinement for this population, such as jails, prisons and homeless shelters. The second part of this paper will explore the new realities of criminal confinement of persons with mental illness. As we will see, incarceration of this vulnerable population in the criminal justice system has caused enormous suffering. If Dostoyevsky was correct that the 'degree of civilization... can be judged by entering its prisons', then by that measure, we are a deeply uncivilized society.

Food can be an important route for transmission of parasites to humans. Compared to other foodborne pathogens in Serbia, foodborne (or potentially foodborne) parasites do not get the attention they undoubtedly deserve. The aim of this article is to give an overview of the most important parasitic pathogens that can be transmitted by food, and that cause disease in humans: Echinococcus, Trichinella, Taenia solium and Toxoplasma gondii. For each of these pathogens, the severity of human diseases they cause, incidence, mortality and case fatality rate among humans in Serbia as well as their prevalence in animal species in Serbia are described. Some of the described foodborne parasites can induce severe disease symptoms in humans associated with high case fatality rates, while others can cause massive outbreaks. All of the aforementioned parasites occur throughout Serbia and cause both severe public health problems and substantial economic losses in livestock production. In conclusion, the control measures of foodborne parasites certainly need to include education of farmers and improvement of veterinary sanitary measures in animal farming and animal waste control.

2014-01-01

Approximately 6500 high school football athletes are treated annually for exertional heat illness (EHI). In 2009, the National Athletic Trainers Association (NATA)-led Inter-Association Task Force (NATA-IATF) released preseason heat acclimatization guidelines to help athletes become accustomed to environmental factors contributing to EHI. This study examines compliance with NATA-IATF guidelines and related EHI prevention strategies. The study used a cross-sectional survey completed by 1142 certified athletic trainers (AT), which captured compliance with 17 NATA-IATF guidelines and EHI prevention strategies in high school football during the 2011 preseason. On average, AT reported football programs complying with 10.4 NATA-IATF guidelines (SD = 3.2); 29 AT (2.5%) reported compliance with all 17. Guidelines with the lowest compliance were as follows: "Single-practice days consisted of practice no more than three hours in length" (39.7%); and "During days 3-5 of acclimatization, only helmets and shoulder pads should be worn" (39.0%). An average of 7.6 EHI prevention strategies (SD = 2.5) were used. Common EHI prevention strategies were as follows: having ice bags/cooler available (98.5%) and having a policy with written instructions for initiating emergency medical service response (87.8%). Programs in states with mandated guidelines had higher levels of compliance with guidelines and greater prevalence of EHI prevention strategies. A low proportion of surveyed high school football programs fully complied with all 17 NATA-IATF guidelines. However, many EHI prevention strategies were voluntarily implemented. State-level mandated EHI prevention guidelines may increase compliance with recognized best practices recommendations. Ongoing longitudinal monitoring of compliance is also recommended.

The most common syndrome is acute mountain sickness (AMS which usually begins within a few hours of ascent and typically consists of headache variably accompanied by loss of appetite, nausea, vomiting, disturbed sleep, fatigue, and dizziness. With millions of travelers journeying to high altitudes every year and sleeping above 2,500 m, acute mountain sickness is a wide-spread clinical condition. Risk factors include home elevation, maximum altitude, sleeping altitude, rate of ascent, latitude, age, gender, physical condition, intensity of exercise, pre-acclimatization, genetic make-up, and pre-existing diseases. At higher altitudes, sleep disturbances may become more profound, mental performance is impaired, and weight loss may occur. If ascent is rapid, acetazolamide can reduce the risk of developing AMS, although a number of high-altitude travelers taking acetazolamide will still develop symptoms. Ibuprofen can be effective for headache. Symptoms can be rapidly relieved by descent, and descent is mandatory, if at all possible, for the management of the potentially fatal syndromes of high-altitude pulmonary and cerebral edema. The purpose of this review is to combine a discussion of specific risk factors, prevention, and treatment options with a summary of the basic physiologic responses to the hypoxia of altitude to provide a context for managing high-altitude illnesses and advising the non-acclimatized high-altitude traveler.

likely due to consumption of contaminated soft cheeses such as queso fresco and queso blanco. The International Life Sciences Institute Risk Science Institute Expert Panel concluded that certain foods pose a high risk for causing listeriosis. High-risk foods have all of the following properties: (1) have...... the potential for contamination with L. monocytogenes; (2) support the growth of L. monocytogenes to high numbers; (3) are ready to eat; (4) require refrigeration; and (5) are stored for an extended period of time. Control strategies are needed in the food chain from preharvest through consumption to minimize...... the likelihood that food will become contaminated by L. monocytogenes and to prevent the growth of the organism to high numbers. The Expert Panel identified three main strategies for ensuring continuous improvement in reducing foodborne listeriosis: (1) preventing contamination of foods with L. monocytogenes; (2...

Full Text Available Perceptions about illnesses may influence self-care and preventive health behaviours. Illness perceptions of the Zika virus (ZIKV infection were investigated under the framework of the Self-Regulation Model of Illness. Illness perception differences between ZIKV and dengue fever were also examined. Lastly, associations between illness perceptions of ZIKV with mosquito prevention practices were studied. Samples were drawn from landline telephone numbers using computer-assisted telephone interviewing in Malaysia. A total of 567 respondents completed the survey between February 2015 and May 2016. The median and interquartile range (IQR for the total six dimensions of illness perceptions score was higher for dengue (23.0 (IQR 17.0–28.0 than ZIKV (20.0 (IRQ 11.0–28.0, p < 0.001. Respondents who planned to have children (OR 1.670, 95% CI 1.035–2.694 vs. no intention to have children and had friends or acquaintances who died of dengue (OR 2.372, 95% CI 1.300–4.327 vs. no friends who died of dengue were more likely to have a higher total score for six illness perceptions for ZIKV compared to dengue. Multivariate analysis indicated that the best predictors for mosquito control practices after the ZIKV outbreak was declared a Public Health Emergency of International Concern, in descending order, were causes, control, timeline, and consequences dimensions of illness perception. Understanding the context in which a person perceives ZIKV may contribute to developing interventions that influence prevention behaviours.

2001-01-01

Jails and prisons have become a final destination for persons with severe mental illness in America. Addiction, homelessness, and fragmentation of services have contributed to the problem, and have underscored the need for new models of service delivery. Project Link is a university-led consortium of five community agencies in Monroe County, New York that spans healthcare, social service and criminal justice systems. The program features a mobile treatment team with a forensic psychiatrist, a dual diagnosis treatment residence, and culturally competent staff. This paper discusses the importance of service integration in preventing jail and hospital recidivism, and describes steps that Project Link has taken towards integrating healthcare, criminal justice, and social services. Results from a preliminary evaluation suggest that Project Link may be effective in reducing recidivism and in improving community adjustment among severely mentally ill patients with histories of arrest and incarceration.

Given their knowledge of the behavioral issues related to psychiatric illness, mental health care providers are in a unique position to help prevent HIV among women with severe mental illness (SMI). We conducted in-depth interviews with providers at two New York City community clinics. We identified three major, interrelated themes pertaining to HIV prevention among women of color with SMI. Interventions that address the barriers that clinicians face in discussing sex, sexuality, and HIV with patients and train providers in the cultural considerations of cross-cultural mental health care are needed to help prevent HIV among women of color with SMI.

Foodborne Pread of Hepatitis A: Recent Studies on Virus Survival, Transfer and Inactivation

Directory of Open Access Journals (Sweden)

Syed A Sattar

2000-01-01

Full Text Available Hepatitis A virus (HAV is responsible for considerable morbidity and economic losses worldwide, and is the only reportable, foodborne viral pathogen in Canada. Outbreaks caused by it occur more frequently in settings such as hospitals, daycare centres, schools, and in association with foods and food service establishments. In recent years, the incidence of hepatitis A has increased in Canada. Many factors, including changing lifestyles and demographics, faster and more frequent travel, and enhanced importation of foods from hepatitis A-endemic regions, may be behind this increase. Despite its increasing significance as a human pathogen, not much was known until recently about the survival and inactivation of HAV, and even less was understood about the effectiveness of measures to prevent and control its foodborne spread. Studies conducted in the past decade have shown that HAV can survive for several hours on human hands and for several days on environmental surfaces indoors. The virus can also retain its infectivity for several days on fruits and vegetables which are often consumed raw, and such imported items have already been incriminated in disease outbreaks. Casual contact between contaminated hands and clean food items can readily lead to a transfer of as much as 10% of the infectious virus. HAV is also relatively resistant to inactivation by heat, gamma irradiation and chemical germicides. In view of these findings, better approaches to prevent the contamination of foods with HAV and more effective methods for its inactivation in foods, on environmental surfaces and on the hands of food handlers are needed.

2011-12-01

Approximately 1.4 million Salmonella infections and 400 deaths occur annually in the United States. Approximately 6% of human Salmonella cases are thought to be associated with reptiles; Salmonella enterica subspecies IV is primarily reptile-associated. During 1-4 December, 2009, three isolates of Salmonella IV 6,7:z4,z24:- with indistinguishable pulsed-field gel electrophoresis (PFGE) patterns were identified through Minnesota Department of Health laboratory-based surveillance. None of the three patients associated with the isolates reported reptile contact; however, all had attended the same potluck dinner. Dinner attendees were asked questions regarding illness history, foods they prepared for and consumed at the event, and pet ownership. Cases were defined as illness in a person who had eaten potluck food and subsequently experienced fever and diarrhoea (three or more loose stools in 24 h) or laboratory-confirmed infection with Salmonella IV matching the outbreak PFGE subtype. Nineteen days after the event, environmental samples were collected from a food preparer's house where two pet bearded dragons were kept. Sixty-six of 73 potluck food consumers were interviewed; 19 cases were identified; 18 persons reported illness but did not meet the case definition. Median incubation period was 19 h (range: 3-26 h). Median duration of illness was 5 days (range: 1-11 days). Consumption of gravy, prepared by the bearded dragons' asymptomatic owner, was associated with illness (16/32 exposed versus 1/12 unexposed; risk ratio: 6.0; exact P = 0.02). Salmonella Labadi was recovered from 10 samples, including from one bearded dragon, the bathroom door knob and sink drain, and the kitchen sink drain. The outbreak PFGE subtype of Salmonella subspecies IV was isolated from vacuum-cleaner bag contents. This foodborne outbreak probably resulted from environmental contamination from bearded dragons. Reptiles pose a community threat when food for public consumption is prepared in

Device-related infections in critically ill patients. Part II: Prevention of ventilator-associated pneumonia and urinary tract infections.

Science.gov (United States)

Di Filippo, A; De Gaudio, A R

2003-12-01

Device utilization in critically ill patients is responsible for a high risk of complications such as catheter-related bloodstream infections (CRBSI), ventilator-associated pneumonia (VAP) and urinary tract infections (UTI). In this article we will review the current status of data regarding the prevention of VAP and UTI. The results of the more recent (5 years) randomized controlled trials are reviewed and discussed. General recommendations include staff education and use of a surveillance program with a restrictive antibiotic policy. Adequate time must be allowed for hand washing and barrier precautions must always be used during device manipulation. Specific measures for VAP prevention are: 1) use of multi-use, closed-system suction catheters; 2) no routine change of the breathing circuit; 3) lubrication of the cuff of the endotracheal tube (ET) with a water-soluble gel; 4) maintenance of patient in semi-recumbent position to improve chest physiotherapy in intubated patients. Specific measures for UTI prevention include: 1) use of a catheter-valve instead of a standard drainage system; 2) use of a silver-alloy, hydro gel-coated latex urinary catheter instead of uncoated catheters. Biofilm represents a new variable: the capacity of bacteria to organize a biofilm on a device surface can explain the difficulty in preventing and eradicating an infection in a critically ill patient. More clinical trials are needed to verify the efficacy of prevention measures of ICU infections.

2018-05-01

The behavior of foodborne bacteria on whole and cut mangoes and the antibacterial effect of Hibiscus sabdariffa calyx extracts and chemical sanitizers against foodborne bacteria on contaminated mangoes were investigated. Mangoes var. Ataulfo and Kent were used in the study. Mangoes were inoculated with Listeria monocytogenes, Shigella flexneri, Salmonella Typhimurium, Salmonella Typhi, Salmonella Montevideo, Escherichia coli strains (O157:H7, non-O157:H7 Shiga toxin-producing, enteropathogenic, enterotoxigenic, enteroinvasive, and enteroaggregative). The antibacterial effect of five roselle calyx extracts (water, ethanol, methanol, acetone, and ethyl acetate), sodium hypochlorite, colloidal silver, and acetic acid against foodborne bacteria were evaluated on contaminated mangoes. The dry extracts obtained with ethanol, methanol, acetone, and ethyl acetate were analyzed by nuclear magnetic resonance spectroscopy to determine solvent residues. Separately, contaminated whole mangoes were immersed in five hibiscus extracts and in sanitizers for 5 min. All foodborne bacteria attached to mangoes. After 20 days at 25 ± 2°C, all foodborne bacterial strains on whole Ataulfo mangoes had decreased by approximately 2.5 log, and on Kent mangoes by approximately 2 log; at 3 ± 2°C, they had decreased to approximately 1.9 and 1.5 log, respectively, on Ataulfo and Kent. All foodborne bacterial strains grew on cut mangoes at 25 ± 2°C; however, at 3 ± 2°C, bacterial growth was inhibited. Residual solvents were not detected in any of the dry extracts by nuclear magnetic resonance. Acetonic, ethanolic, and methanolic roselle calyx extracts caused a greater reduction in concentration (2 to 2.6 log CFU/g) of all foodborne bacteria on contaminated whole mangoes than the sodium hypochlorite, colloidal silver, and acetic acid. Dry roselle calyx extracts may be a potentially useful addition to disinfection procedures of mangoes.

The economic impact of pressure ulcer prevention and treatment is high. The results of cost-of-illness studies can assist the planning, allocation, and priority setting of healthcare expenditures to improve the implementation of preventive measures. Data on the cost of current practice of pressure ulcer prevention or treatment in Flanders, a region of Belgium, is lacking. To examine the cost of pressure ulcer prevention and treatment in an adult population in hospitals and nursing homes from the healthcare payer perspective. A cost-of-illness study was performed using a bottom-up approach. Hospitals and nursing homes in Flanders, a region of Belgium. Data were collected in a series of prospective multicentre cross-sectional studies between 2008 and 2013. Data collection included data on risk assessment, pressure ulcer prevalence, preventive measures, unit cost of materials for prevention and treatment, nursing time measurements for activities related to pressure ulcer prevention and treatment, and nursing wages. The cost of pressure ulcer prevention and treatment in hospitals and nursing homes was calculated as annual cost for Flanders, per patient, and per patient per day. The mean (SD) cost for pressure ulcer prevention was €7.88 (8.21) per hospitalised patient at risk per day and €2.15 (3.10) per nursing home resident at risk per day. The mean (SD) cost of pressure ulcer prevention for patients and residents identified as not at risk for pressure ulcer development was €1.44 (4.26) per day in hospitals and €0.50 (1.61) per day in nursing homes. The main cost driver was the cost of labour, responsible for 79-85% of the cost of prevention. The mean (SD) cost of local treatment per patient per day varied between €2.34 (1.14) and €77.36 (35.95) in hospitals, and between €2.42 (1.15) and €16.18 (4.93) in nursing homes. Related to methodological differences between studies, the cost of pressure ulcer prevention and treatment in hospitals and nursing

Design Prospective recording of newly occurred injuries and illnesses. Setting 13th International Association of Athletics Federations World Championships in Athletics 2011 in Daegu, Korea. Participants National team and Local Organising Committee physicians; and 1851 registered athletes. Main outcome measures Incidence and characteristics of newly incurred injuries and illnesses. Results 82% of athletes were covered by medical teams participating with a response rate of 94%. A total of 249 injuries were reported, representing an incidence of 134.5 injuries per 1000 registered athletes, and 119 (48%) resulted in time loss from sport. A total of 185 injuries affected the lower limb (74%). Hamstring strain was the main diagnosis and 67% resulted in absence from sport. Overuse (n=148; 59%) was the predominant cause. A total of 126 illnesses were reported, signifying an incidence of 68.1 per 1000 registered athletes. Upper respiratory tract infection was the most common reported diagnosis (18%), followed by exercise-induced dehydration (12%), and gastroenteritis/diarrhoea (10%). The highest incidences of injuries were found in combined events and middle and long-distance events, and of illness in race walking events. Conclusion During elite Athletics World Championships, 135 injuries, 60 time-loss injuries and 68 illnesses per 1000 registered athletes were reported. Higher risks of injuries were found in combined events and long-distance runs. Preventive interventions should focus on overuse injuries and hamstring strains, decreasing the risk of transmission of infectious diseases, appropriate event scheduling and heat acclimatisation.

Mattejat, Fritz; Remschmidt, Helmut

2008-06-01

The children of mentally ill parents have a higher risk of developing mental illnesses themselves over the course of their lives. This known risk must be taken into account in the practical provision of health care. Selective literature review. The increased psychiatric risk for children of mentally ill parents is due partly to genetic influences and partly to an impairment of the parent-child interaction because of the parent's illness. Furthermore, adverse factors are more frequent in these families, as well as a higher risk for child abuse. Genetic and psychosocial factors interact with one another. For example, genetic factors moderate environmental effects; that is, the effect of adverse environmental factors depends on the genetic substrate. Preventive measures for children of mentally ill parents urgently need improvement. In this article, positively evaluated programs of preventive measures are discussed. Essential prerequisites for success include appropriate, specialized treatment of the parental illness, psychoeducative measures, and special support (e.g. self-help groups) as indicated by the family's particular needs.

Brawner, Bridgette M; Jemmott, Loretta Sweet; Wingood, Gina; Reason, Janaiya; Mack, Niya

Heterosexually active Black adolescents with mental illnesses are at increased risk for sexually transmitted infections (STIs), including HIV. However, few HIV/STI prevention interventions exist for this demographic. We held seven focus groups (N = 33) to elucidate social, cultural, and psychological factors that influence HIV/STI risk-related sexual behaviors in this understudied population. Seven themes emerged: (a) Blackness and media portrayals, (b) Blackness as a source of cultural resilience and pride, (c) psychosocial determinants of condom use, (d) consequences of engaging in sexual activity, (e) attitudes and beliefs toward sexual behaviors, (f) benefits of sexual activity, and (g) coping mechanisms. Participants also supported the feasibility of and interest in HIV/STI prevention programs integrated with mental health treatment. Transportation, potential breaches of confidentiality, and time were noted barriers to participation. Psychoeducational, skills-based programs are needed to address the sequelae of mental illnesses as they relate to the sexual decision-making process in adolescents.

Käferstein, F K; Motarjemi, Y; Bettcher, D W

1997-01-01

In the globalized political economy of the late 20th century, increasing social, political, and economic interdependence is occurring as a result of the rapid movement of people, images, values, and financial transactions across national borders. Another consequence of the increase in transnational trade, travel, and migration is the greater risk of cross-border transmission of infectious diseases. As the world becomes more interconnected, diseases spread more rapidly and effectively. With more than one million people crossing international borders every day, and with the globalization of food production, manufacturing, and marketing, the risk of infectious disease transmission is greater. Economic globalization has also increased the need for governmental budget austerity, and consequent national preparedness has been eroded. The emergence of new infectious diseases, as well as the reemergence of old ones, thus represents a crucial transnational policy issue. These problems cannot be resolved by national governments alone; they require international cooperation. This article analyzes the role of foodborne disease surveillance programs, nationally and internationally, in the control of foodborne diseases.

Norovirus (NoV) is the predominant cause of foodborne disease outbreaks. Virus contamination may occur during all steps of food processing, from production to preparation and serving. The relative importance of these different routes of contamination is unknown. The purpose of this study was to estimate the proportions of outbreaks caused by asymptomatic and symptomatic food handlers (FHs). Reports of foodborne NoV and sapovirus outbreaks (n=191) that occurred over a 7-year period were extracted, reviewed, and categorized according to the available evidence for source of contamination. In 64 (34%) of the outbreaks, contamination from FHs took place during preparation or serving of food. In the majority of these outbreaks (n=41; 64%), the FHs were asymptomatic during food handling. Some had been in contact with ill household members before handling the food and remained asymptomatic; others developed symptoms shortly after or were post-symptomatic. In 51 (27%) of the outbreaks, contamination occurred during production of the food, and in 55 (29%) of the outbreaks, contamination had supposedly occurred after serving a guest at a self-serve buffet. Guidelines regarding exclusion of FHs where household members suffer from gastroenteritis could limit the number of outbreaks. © The Author 2014.

Mentally ill parents are impaired in their ability to care for their children. To support the affected families from the perspective of the parents and the children alike a close cooperation between the institutions of psychiatry and child-welfare is of utmost importance. In the district of Mettmann a cooperation agreement was concluded to realize a cross-system concept to care for the families with mentally ill parents. To prevent children from developing psychiatric disorders the taboo of the psychiatric diseases has to be overcome, an early diagnostic clarification to be reached, and multiinstitutional help to be implemented. In the article the experience in dealing with the affected families in a multidisciplinary context is described.

To prepare for the upcoming 2020 Summer Olympics and Paralympics in Tokyo, all participants, including the athletes, staff, and spectators, will need to familiarize themselves with Tokyo's hot and humid summer conditions. This paper uses the wet-bulb globe temperature (WBGT) index, which estimates the risk of heat illness, to compare climate conditions of sports events in Tokyo with the conditions of the past three Summer Olympics (held in Rio de Janeiro, London, and Beijing) and to subsequently detail the need for establishing appropriate countermeasures. We compared WBGT results from the past three Summer Olympics with the same time periods in Tokyo during 2016. There was almost no time zone where a low risk of heat illness could be expected during the time frame of the upcoming 2020 Tokyo Olympics. We also found that Tokyo had a higher WBGT than any of those previous host cities and is poorly suited for outdoor sporting events. Combined efforts by the official organizers, government, various related organizations, and the participants will be necessary to deal with these challenging conditions and to allow athletes to perform their best, as well as to prevent heat illnesses among staff and spectators. The sporting committees, as well as the Olympic organizing committee, should consider WBGT measurements in determining the venues and timing of the events to better avoid heat illness and facilitate maximum athletic performance.

Nanomaterial-based sensors for detection of foodborne bacterial pathogens and toxins as well as pork adulteration in meat products

Full Text Available Food safety draws considerable attention in the modern pace of the world owing to rapid-changing food recipes and food habits. Foodborne illnesses associated with pathogens, toxins, and other contaminants pose serious threat to human health. Besides, a large amount of money is spent on both analyses and control measures, which causes significant loss to the food industry. Conventional detection methods for bacterial pathogens and toxins are time consuming and laborious, requiring certain sophisticated instruments and trained personnel. In recent years, nanotechnology has emerged as a promising field for solving food safety issues in terms of detecting contaminants, enabling controlled release of preservatives to extend the shelf life of foods, and improving food-packaging strategies. Nanomaterials including metal oxide and metal nanoparticles, carbon nanotubes, and quantum dots are gaining a prominent role in the design of sensors and biosensors for food analysis. In this review, various nanomaterial-based sensors reported in the literature for detection of several foodborne bacterial pathogens and toxins are summarized highlighting their principles, advantages, and limitations in terms of simplicity, sensitivity, and multiplexing capability. In addition, the application through a noncross-linking method without the need for any surface modification is also presented for detection of pork adulteration in meat products.

Biocontrol and Rapid Detection of Food-borne Pathogens Using Bacteriophages and Endolysins

Directory of Open Access Journals (Sweden)

Jaewoo eBai

2016-04-01

Full Text Available Bacteriophages have been suggested as natural food preservatives as well as rapid detection materials for food-borne pathogens in various foods. Since Listeria monocytogenes-targeting phage cocktail (ListShield was approved for applications in foods, numerous phages have been screened and experimentally characterized for phage applications in foods. A single phage and phage cocktail treatments to various foods contaminated with food-borne pathogens including E. coli O157:H7, Salmonella enterica, Campylobacter jejuni, Listeria monocytogenes, Staphylococcus aureus, Cronobacter sakazakii, and Vibrio spp. revealed that they have great potential to control various food-borne pathogens and may be alternative for conventional food preservatives. In addition, phage-derived endolysins with high host specificity and host lysis activities may be preferred to food applications rather than phages. For rapid detection of food-borne pathogens, cell-wall binding domains (CBDs from endolysins have been suggested due to their high host-specific binding. Fluorescence-tagged CBDs have been successfully evaluated and suggested to be alternative materials of expensive antibodies for various detection applications. Most recently, reporter phage systems have been developed and tested to confirm their usability and accuracy for specific detection. These systems revealed some advantages like rapid detection of only viable pathogenic cells without interference by food components in a very short reaction time, suggesting that these systems may be suitable for monitoring of pathogens in foods. Consequently, phage is the next-generation biocontrol agent as well as rapid detection tool to confirm and even identify the food-borne pathogens present in various foods.

Consumer responses to food product recalls have been documented, but there is little information on how consumers respond to illnesses or outbreaks associated with food service facilities. This study uses an on-line survey of 885 adults conducted in 2012 to determine how respondents changed their dining behavior following personal experiences with and secondhand reports of gastrointestinal illness believed to be associated with food service facilities. In response to personally experiencing gastrointestinal illness that they attributed to a food service facility, 90% of survey participants reported that they avoided the implicated facility for a time following the incident; almost one-half decided to never return to the facility they believed had made them ill. In response to a secondhand report of gastrointestinal illness, 86% of respondents reported they would avoid the implicated facility for a time, and 22% said they would never return to the facility. After both personal experiences of illness and secondhand reports of illness, consumer responses were significantly more severe toward the implicated facility than toward all other food service facilities. Frequent diners avoided facilities for shorter periods of time and were less likely to never go back to a facility than were infrequent diners. The survey results indicate that 24 to 97 fewer meals were purchased per respondent, or a 11 to 20% reduction in meals purchased outside the home, in the year following respondents' illness. Future estimates of the economic burden of foodborne illnesses, including those caused by noroviruses, should consider the impacts on the food service industry attributable to changes in consumer behavior, in addition to health care costs and loss of productivity.

Food-borne pathogens are ongoing problems, and new pathogens are emerging. The impact of fungi, however, is largely underestimated. Recently, commercial yogurts contaminated with Mucor circinelloides were sold, and >200 consumers became ill with nausea, vomiting, and diarrhea. Mucoralean fungi cause the fatal fungal infection mucormycosis, whose incidence has been continuously increasing. In this study, we isolated an M. circinelloides strain from a yogurt container, and multilocus sequence typing identified the strain as Mucor circinelloides f. circinelloides. M. circinelloides f. circinelloides is the most virulent M. circinelloides subspecies and is commonly associated with human infections, whereas M. circinelloides f. lusitanicus and M. circinelloides f. griseocyanus are less common causes of infection. Whole-genome analysis of the yogurt isolate confirmed it as being close to the M. circinelloides f. circinelloides subgroup, with a higher percentage of divergence with the M. circinelloides f. lusitanicus subgroup. In mating assays, the yogurt isolate formed sexual zygospores with the (-) M. circinelloides f. circinelloides tester strain, which is congruent with its sex locus encoding SexP, the (+) mating type sex determinant. The yogurt isolate was virulent in murine and wax moth larva host systems. In a murine gastromucormycosis model, Mucor was recovered from fecal samples of infected mice for up to 10 days, indicating that Mucor can survive transit through the GI tract. In interactions with human immune cells, M. circinelloides f. lusitanicus induced proinflammatory cytokines but M. circinelloides f. circinelloides did not, which may explain the different levels of virulence in mammalian hosts. This study demonstrates that M. circinelloides can spoil food products and cause gastrointestinal illness in consumers and may pose a particular risk to immunocompromised patients. Importance: The U.S. FDA reported that yogurt products were contaminated with M

Park, Myoung Su; Bahk, Gyung Jin

2015-12-01

Many studies have attempted to accurately estimate the overall number of cases of foodborne illness, but there have not been many attempts to estimate the burden of foodborne disease caused by natural toxic compounds. This study estimated the number of cases due to specific natural toxins (seafood toxins, plant toxins, and mycotoxins) during 2008-2012 in South Korea, using data from the Health Insurance Review and Assessment Service (HIRA), while accounting for uncertainty in the estimate. The estimated annual occurrences of foodborne illness from natural toxic agents were 1088 (90% credible interval [CrI]: 883-1315), which suggests there are 21 times more cases than are reported, with 45.6% (n=496 [388-614]) and 54.4% (n=592 [423-790]), accounting for inpatient stays and outpatient visits, respectively. Among toxins, mushroom and plant toxins caused the highest illnesses, followed by toxic agents in seafood and mycotoxins. The 55-59year olds had the highest proportion of illnesses and those over the age of 40 accounted for 70.6% of all cases. The cases caused by mushroom poison, poisonous plants, and seafood toxins showed clear seasonal and regional differences. These results will be useful to food safety policymakers for the prevention and control of natural food poisons in South Korea. Copyright © 2015 Elsevier Ltd. All rights reserved.

Bioluminescent bioreporter sensing of foodborne toxins

Fraley, Amanda C.; Ripp, Steven; Sayler, Gary S.

2004-06-01

Histamine is the primary etiological agent in the foodborne disease scombrotoxicosis, one of the most common food toxicities related to fish consumption. Procedures for detecting histamine in fish products are available, but are often too expensive or too complex for routine use. As an alternative, a bacterial bioluminescent bioreporter has been constructed to develop a biosensor system that autonomously responds to low levels of histamine. The bioreporter contains a promoterless Photorhabdus luminescens lux operon (luxCDABE) fused with the Vibrio anguillarum angR regulatory gene promoter of the anguibactin biosynthetic operon. The bioreporter emitted 1.46 times more bioluminescence than background, 30 minutes after the addition of 100mM histamine. However, specificity was not optimal, as this biosensor generated significant bioluminescence in the presence of L-proline and L-histidine. As a means towards improving histamine specificity, the promoter region of a histamine oxidase gene from Arthrobacter globiformis was cloned upstream of the promotorless lux operon from Photorhabdus luminescens. This recently constructed whole-cell, lux-based bioluminescent bioreporter is currently being tested for optimal performance in the presence of histamine in order to provide a rapid, simple, and inexpensive model sensor for the detection of foodborne toxins.

Foodborne pathogens can be associated with a wide variety of food products and it is very important to identify them to supply safe food and prevent foodborne infections. Since traditional techniques are timeconsuming and laborious, this study was designed for rapid identification and clustering of foodborne pathogens isolated from various restaurants in Al-Qassim region, Kingdom of Saudi Arabia (KSA) using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Sixty-nine bacterial and thirty-two fungal isolates isolated from 80 food samples were used in this study. Preliminary identification was carried out through culture and BD Phoenix™ methods. A confirmatory identification technique was then performed using MALDI-TOF MS. The BD Phoenix results revealed that 97% (67/69 isolates) of bacteria were correctly identified as 75% Enterobacter cloacae, 95.45% Campylobacter jejuni and 100% for Escherichia coli, Salmonella enterica, Staphylococcus aureus, Acinetobacter baumannii, and Klebsiella pneumoniae. While 94.44% (29/32 isolates) of fungi were correctly identified as 77.77% Alternaria alternate, 88.88% Aspergillus niger and 100% for Aspergillus flavus, Penicillium digitatum, Candida albicans and Debaryomyces hansenii. However, all bacterial and fungal isolates were 100% properly identified by MALDI-TOF MS fingerprinting with a score value ≥2.00. A gel view illustrated that the spectral peaks for the identified isolates fluctuate between 3,000 and 10,000 Da. The results of main spectra library (MSP) dendrogram showed that the bacterial and fungal isolates matched with 19 and 9 reference strains stored in the Bruker taxonomy, respectively. Our results indicated that MALDI-TOF MS is a promising technique for fast and accurate identification of foodborne pathogens.

This research aimed to enhance self-care among rubber farmers for preventing work-related illness. The project used Action Research's four phase iterative process: fact-finding to understand the problems, action planning, action plan implementation, and evaluation and reflection on action plan impacts. Sixty-six participants (46 rubber farmers and 20 community stakeholders) were purposively recruited from two villages in the top 10 rubber producing provinces in Northeastern Thailand. Demographic and work-related illness data were collected in face-to-face structured interviews, Focus group interviews and participant observations were used to collect data in each project phase. Night group meetings were held throughout the research phases. The intervention included training workshops and establishing a community health education team for ongoing farmer support. Results showed improved farmer self-care behaviors and establishment of a community health education team to encourage farmers to care for themselves properly. Community nurses, other health personnel, and the Thai government can build on initiatives like this to strengthen occupational health and safety practices and services policy for rubber farmers. © 2018 Wiley Periodicals, Inc.

Use of irradiation to control infectivity of food-borne parasites

International Nuclear Information System (INIS)

1993-01-01

Food-borne parasitic diseases are common throughout the world, pose significant health problems and cause economic losses in terms of agricultural commodities and human productivity. The diseases usually occur through consumption of raw or partially cooked foods with are infected by various parasites (e.g. tapeworms, roundworms, flukes, parasitic protozoa, etc.). The problem is significant in developing countries where the population has the habit of consuming raw food of animal origin. Available data, with the exception of data on Trichinella spiralis, a parasitic nematode, were insufficient for the use of irradiation technology to control food-borne parasites. Therefore, a Co-ordinated Research Programme (CRP) on the Use of Irradiation to Control Infectivity of Food-Borne Parasites was implemented by the FAO/IAEA in 1986. The results of the work carried out over five years (1986-1991) by twelve researchers participating in the programme, have established conclusively the potential for application of food irradiation in the control of liver flukes, tapeworms, roundworms, trichinosis, toxoplasmosis, etc. This report includes the conclusions and recommendations of the participants concerning the results obtained and need for further research.

Endophytes are a potential source of novel bioactive compounds with medicinal properties. In this study, 41 endophytic bacteria (EB) were isolated from tissues of a medicinally important plant Taxus brevifolia (Pacific yew). The objective was to screen all the EB isolates for their antibacterial effects against five foodborne pathogenic bacteria: Bacillus cereus ATCC10876, Staphylococcus aureus ATCC12600, Listeria monocytogenes ATCC19115, Escherichia coli ATCC43890, and Salmonella Typhimurium ATCC19585. Among the EB isolates, T. brevifolia seed (TbS)-8, T. brevifolia fleshy part of fruit (TbFl)-10, T. brevifolia leaf (TbL)-22, TbS-29, and TbL-34 exerted significant antibacterial activity against the tested foodborne pathogens. Especially TbFl-10 showed the highest antibacterial activity against all the tested bacteria and was identified as Paenibacillus kribbensis (Pk). Furthermore, an ethyl acetate extract of Pk-TbFl-10 possessed antibacterial activities against the tested five foodborne pathogenic bacteria, with zones of inhibition from 15.71 ± 2.85 to 13.01 ± 2.12 mm. Scanning electron microscopy analysis revealed ruptured, lysed, shrunk, and swollen cells of all the tested foodborne pathogens treated with the ethyl acetate extract of Pk-TbFl-10, suggesting that a metabolite(s) of Pk-TbFl-10 penetrates the cell membrane and causes cell lysis leading to cell death. Our results indicate that Pk-TbFl-10 isolated from T. brevifolia can serve as a novel source of natural antibacterial agents against foodborne pathogenic bacteria, with potential applications in the pharmaceutical industry.

Injuries and infectious diseases show high levels of morbidity at home. It is known that diseases associated with the consumption of contaminated or poorly preserved food, can be significantly reduced if proper hygiene practices are observed. This article analyzes the main risks associated with household food consumption and aims to highlight some of the recommendations that are still widely disregarded. In particular, we highlight the issues concerning the management of food (especially cooking and storage) and water (mineral and tap water), as well as good manufacturing practices that the consumer have to take to avoid food contamination. For this purpose, a detailed information on prevention would provide people with a greater awareness of risk and, therefore, a improved perception to the real dangers.

Nano-particle enhanced impedimetric biosensor for detection of foodborne pathogens

International Nuclear Information System (INIS)

Kim, G; Om, A S; Mun, J H

2007-01-01

Recent outbreaks of foodborne illness have been increased the need for rapid and sensitive methods for detection of these pathogens. Conventional methods for pathogens detection and identification involve prolonged multiple enrichment steps. Even though some immunological rapid assays are available, these assays still need enrichment steps result in delayed detection. Biosensors have shown great potential for rapid detection of foodborne pathogens. They are capable of direct monitoring the antigen-antibody reactions in real time. Among the biosensors, impedimetric biosensors have been widely adapted as an analysis tool for the study of various biological binding reactions because of their high sensitivity and reagentless operation. In this study a nanoparticle-enhanced impedimetric biosensor for Salmonella enteritidis detection was developed which detected impedance changes caused by the attachment of the cells to the anti-Salmonella antibodies immobilized on interdigitated gold electrodes. Successive immobilization of neutravidin followed by anti-Salmonella antibodies was performed to the sensing area to create a biological detection surface. To enhance the impedance responses generated by antigen-antibody reactions, anti-Salmonella antibody conjugated nanoparticles were introduced on the sensing area. Using a portable impedance analyzer, the impedance across the interdigital electrodes was measured after the series of antigen-antibody bindings. Bacteria cells present in solution attached to capture antibodies and became tethered to the sensor surface. Attached bacteria cells changed the dielectric constant of the media between the electrodes thereby causing a change in measured impedance. Optimum input frequency was determined by analyzing frequency characteristics of the biosensor over ranges of applied frequencies from 10 Hz to 400 Hz. At 100 Hz of input frequency, the biosensor was most sensitive to the changes of the bacteria concentration and this frequency

The Injury/Illness Performance Project (IIPP): A Novel Epidemiological Approach for Recording the Consequences of Sports Injuries and Illnesses

Science.gov (United States)

Fuller, Colin; Jaques, Rod; Hunter, Glenn

2013-01-01

Background. Describing the frequency, severity, and causes of sports injuries and illnesses reliably is important for quantifying the risk to athletes and providing direction for prevention initiatives. Methods. Time-loss and/or medical-attention definitions have long been used in sports injury/illness epidemiology research, but the limitations to these definitions mean that some events are incorrectly classified or omitted completely, where athletes continue to train and compete at high levels but experience restrictions in their performance. Introducing a graded definition of performance-restriction may provide a solution to this issue. Results. Results from the Great Britain injury/illness performance project (IIPP) are presented using a performance-restriction adaptation of the accepted surveillance consensus methodologies. The IIPP involved 322 Olympic athletes (males: 172; female: 150) from 10 Great Britain Olympic sports between September 2009 and August 2012. Of all injuries (n = 565), 216 were classified as causing time-loss, 346 as causing performance-restriction, and 3 were unclassified. For athlete illnesses (n = 378), the majority (P < 0.01) resulted in time-loss (270) compared with performance-restriction (101) (7 unclassified). Conclusions. Successful implementation of prevention strategies relies on the correct characterisation of injury/illness risk factors. Including a performance-restriction classification could provide a deeper understanding of injuries/illnesses and better informed prevention initiatives. PMID:26464883

The objective of this study was i) to quantify the risk of hepatitis E for Swiss consumers by specified pork products and ii) to estimate the total burden of human food-borne hepatitis E in Switzerland. A quantitative risk assessment from slaughter to consumption was carried out according to the Codex Alimentarius framework. In the hazard characterization, assumptions were made due to the lack of a dose-response relationship for oral exposure to hepatitis E virus (HEV). The prevalence of HEV in 160 pig livers of 40 different Swiss fattening farms was examined and determined to be 1.3% (CI 0.3%; 4.4%). This result was used as input in the risk assessment model, together with data from other published studies. The annual burden of hepatitis E was estimated in terms of Disability Adjusted Life Years (DALY), using data about hepatitis E cases diagnosed between 2010 and 2015 at two major hospitals located in the canton Ticino. Only the risk of foodborne hepatitis E from products containing pork liver was evaluated, as those containing only pork meat could not be evaluated because of lack of data on HEV load in pork. Assuming that successful oral infection occurs in 1% of servings contaminated with high HEV loads (>10 5 genome copies), and that acute illness develops in 5% of susceptible consumers, the most likely annual number of foodborne hepatitis E cases in Switzerland was estimated to be 1481 (95% CI 552; 4488) if all products containing pork liver were considered. If only high-risk products, such as plain pork liver and liver sausages (e.g. Saucisse au Foie), were considered, the annual number of cases was estimated to be 176 (95% CI 64; 498). We were unable to calculate the total burden of hepatitis E in Switzerland due to lack of data. Yet, for the canton Ticino, it was shown that a significant increase had occurred from 50 DALY per 100,000 inhabitants in 2015. This change could partly be due to an increased reporting and higher awareness among medical

2008-03-01

Despite structured enforcement of food hygiene requirements known to prevent foodborne disease outbreaks, catering businesses continue to be the most common setting for outbreaks in the United Kingdom. In a matched case control study of catering businesses, 148 businesses associated with outbreaks were compared with 148 control businesses. Hazard analysis critical control point systems and/or formal food hygiene training qualifications were not protective. Food hygiene inspection scores were not useful in predicting which catering businesses were associated with outbreaks. Businesses associated with outbreaks were more likely to be larger small and medium-sized enterprises (SMEs) or to serve Chinese cuisine and less likely to have the owner or manager working in the kitchen, but when size of the SME was taken into account these two differences were no longer significant. In larger businesses, case businesses were more likely to be hotels and were more commonly associated with viral foodborne outbreaks, but there was no explanation within the data for this association.

Such an outbreak results in direct, measurable expenses for acute care management, as well as numerous indirect (and less quantifiable) costs to those affected, the hospital, and the wider community. This article describes the significant direct costs incurred as a result of a nosocomial outbreak of Salmonella infection involving patients and staff. Information on costs incurred by the hospital was gathered from a number of sources. The data were grouped into 4 sections (medical costs, investigative costs, lost productivity costs, and miscellaneous) with use of an existing tool for calculating the economic impact of foodborne illness. The outbreak cost the hospital more than AU $120, 000. (US $95,000). This amount is independent of more substantial indirect costs. Salmonella infections are preventable. Measures to aid the prevention of costly outbreaks of nosocomial salmonellosis, although available, require an investment of both time and money. We suggest that dedication of limited resources toward such preventive strategies as education is a practical and cost-effective option for health care facilities.

Cultures all over the world have evolved illness representations that can accommodate not only new diseases, but also new epistemologies for explaining disease. This paper examines illness representations in Sub-Saharan Africa, and how these have responded to the emergence of AIDS. Indigenous views of illness (particularly STDs) exhibit coherent structure, in which causation, prevention and treatment relate to one another in functional ways. As an STD, an epidemic, and a disease which leads to premature death, AIDS lends itself readily to accommodation into established indigenous representations of illness. Even biomedical views of causation can be readily incorporated into traditional views of how illnesses are caused. However, biomedical and traditional views concerning prevention appear to be in direct conflict with one another, with potentially hazardous consequences. Research exploring the extent to which indigenous beliefs may be influencing people's decisions about safe sex could offer useful insights for AIDS prevention programs.

&C). Foods implicated in outbreaks were classified by their ingredients as simple foods (i.e. belonging to one single food category), or complex foods (i.e. belonging to multiple food categories). For each agent, the data from simple-food outbreaks were summarized, and the proportion of outbreaks caused...... by each category was used to define the probability that an outbreak was caused by a source. For the calculation of the number of outbreaks attributed to each source, simple-food outbreaks were attributed to the single food category in question, and complex-food outbreaks were partitioned to each category......Foodborne pathogens are responsible for an increasing burden of disease worldwide. Knowledge on the contribution of different food sources and water for disease is essential to prioritize food safety interventions and implement appropriate control measures.

To assess the efficacy and safety of esomeprazole in preventing upper gastrointestinal (GI) bleeding in critically ill Chinese patients, using cimetidine as an active comparator. A pre-specified non-inferiority limit (5%) was used to compare rates of significant upper GI bleeding in this randomized, double-blind, parallel-group, phase 3 study across 27 intensive care units in China. Secondary endpoints included safety and tolerability measures. Patients required mechanical ventilation and had at least one additional risk factor for stress ulcer bleeding. Patients were randomized to receive either active esomeprazole 40 mg, as a 30-min intravenous (IV) infusion twice daily, and an IV placebo cimetidine infusion or active cimetidine 50 mg/h, as a continuous infusion following an initial bolus of 300 mg, and placebo esomeprazole injections, given up to 14 days. Patients were blinded using this double-dummy technique. Of 274 patients, 2.7% with esomeprazole and 4.6% with cimetidine had significant upper GI bleeding (bright red blood in the gastric tube not clearing after lavage or persistent Gastroccult-positive "coffee grounds" material). Non-inferiority of esomeprazole to cimetidine was demonstrated. The safety profiles of both drugs were similar and as expected in critically ill patients. Esomeprazole is effective in preventing upper GI bleeding in critically ill Chinese patients, as demonstrated by the non-inferiority analysis using cimetidine as an active control.

Full Text Available Medical students experience higher rates of mental illness than the general population. With competition rising for success in medical school, and residency, increasing incidence of distress are leading this population to experience higher rates of thoughts of dropping out of school, and even suicide. Since many stigmas deter medical students from receiving mental health counseling, such as the perceived inability to handle the stresses of medical school, and the potential lack of competitiveness for residencies if reported, prevention of mental illness may be a better course to take in reducing prevalence in this population. Regular exercise has demonstrated a positive effect on not only promoting physical health, but also mental health. Exercise encourages a healthy mood, positive self esteem, and better cognition, while decreasing the chances of depression, anxiety, and burnout. Implementing exercise time into medical school curriculums, just like the basic sciences, albeit for less time in the day, could provide a feasible way to ensure that all students are taking time to partake in this important activity for their well being. Though medical schools are rigid with attempts to make changes in their curriculum, thirty minutes a day, three to five times a week of exercise of the students’ choice not only is more cost effective than counseling, but it also reduces the chances that they will experience burnout, which if left untreated could transcend into a compromised training experience.

Lucas, Todd; Alexander, Sheldon; Firestone, Ira; Lebreton, James M

2009-03-01

Characteristics of individuals and illnesses can both influence receptivity to preventative health messages. We examined whether receptivity to health messages depends on interactions between illness characteristics and dispositional concern for justice. Participants considered the preventability of six illnesses after exposure to a message that manipulated personal responsibility for illness. Paradoxically, participants with strong just world beliefs reported greater preventability for less preventable illnesses, such as brain cancer, when exposed to an unpreventable health message. In parallel, participants with low justice beliefs reported less preventability for lung cancer when exposed to a preventable message. This just world boomerang effect suggests that individual dispositions and illness characteristics can interact in ways that can produce either acquiescence or opposition to persuasive health messages.

Full Text Available Foodborne pathogens are causing a great number of diseases with significant effects on human health and economy. The characteristics of the most common pathogenic bacteria (Bacillus cereus, Campylobacter jejuni, Clostridium botulinum, Clostridium perfringens, Cronobacter sakazakii, Esherichia coli, Listeria monocytogenes, Salmonella spp., Shigella spp., Staphylococccus aureus, Vibrio spp. and Yersinia enterocolitica, viruses (Hepatitis A and Noroviruses and parasites (Cyclospora cayetanensis, Toxoplasma gondii and Trichinella spiralis, together with some important outbreaks, are reviewed. Food safety management systems based on to classical hazard-based approach has been proved to be inefficient, and risk-based food safety approach is now suggested from leading researchers and organizations. In this context, a food safety management system should be designed in a way to estimate the risks to human health from food consumption and to identify, select and implement mitigation strategies in order to control and reduce these risks. In addition, the application of suitable food safety education programs for all involved people in the production and consumption of foods is suggested.

Neglected parasitic infections in the United States: toxoplasmosis.

Jones, Jeffrey L; Parise, Monica E; Fiore, Anthony E

2014-05-01

Toxoplasma gondii is a leading cause of severe foodborne illness in the United States. Population-based studies have found T. gondii infection to be more prevalent in racial/ethnic minority and socioeconomically disadvantaged groups. Soil contaminated with cat feces, undercooked meat, and congenital transmission are the principal sources of infection. Toxoplasmosis-associated illnesses include congenital neurologic and ocular disease; acquired illness in immunocompetent persons, most notably ocular disease; and encephalitis or disseminated disease in immunosuppressed persons. The association of T. gondii infection with risk for mental illness is intriguing and requires further research. Reduction of T. gondii in meat, improvements in hygiene and food preparation practices, and reduction of environmental contamination can prevent toxoplasmosis, but more research is needed on how to implement these measures. In addition, screening and treatment may help prevent toxoplasmosis or reduce the severity of disease in some settings.

Advances and Challenges in Viability Detection of Foodborne Pathogens

2016-11-01

Full Text Available Foodborne outbreaks are a serious public health and food safety concern worldwide. There is a great demand for rapid, sensitive, specific, and accurate methods to detect microbial pathogens in foods. Conventional methods based on cultivation of pathogens have been the gold standard protocols; however, they take up to a week to complete. Molecular assays such as polymerase chain reaction (PCR, sequencing, microarray technologies have been widely used in detection of foodborne pathogens. Among molecular assays, PCR technology conventional and real-time PCR (qPCR is most commonly used in the foodborne pathogen detection because of its high sensitivity and specificity. However, a major drawback of PCR is its inability to differentiate the DNA from dead and viable cells, and this is a critical factor for the food industry, regulatory agencies and the consumer. To remedy this shortcoming, researchers have used biological dyes such as ethidium monoazide (EMA and propidium monoazide (PMA to pretreat samples before DNA extraction to intercalate the DNA of dead cells in food samples, and then proceed with regular DNA preparation and qPCR. By combining PMA treatment with qPCR (PMA-qPCR, scientists have applied this technology to detect viable cells of various bacterial pathogens in foods. The incorporation of PMA into PCR-based assays for viability detection of pathogens in foods has increased significantly in the last decade. On the other hand, some downsides with this approach have been noted, particularly to achieve complete suppression of signal of DNA from the dead cells present in some particular food matrix. Nowadays, there is a tendency of more and more researchers adapting this approach for viability detection; and a few commercial kits based on PMA are available in the market. As time goes on, more scientists apply this approach to a broader range of pathogen detections, this viability approach (PMA or other chemicals such as platinum compound

The purpose of the study is to assess the epidemiological situation of foodborne infections and intoxications in Poland in 2012. The evaluation was based on analysis of information from reports of epidemiological investigations in foodborne outbreaks, submitted by the sanitary-epidemiological stations to the Department of Epidemiology, NIZP-PZH annual bulletins (Czarkowski MP et al. "Infectious diseases and poisonings in Poland", 2006-2012. Warsaw, NIPH-NIH and CSI). In Poland in 2012 there was observed decrease in the number of infections intoxications both of bacterial and viral origin. It was recorded only one case of trichinellosis. There were reported 491 outbreaks of foodborne poisonings or infections included 5 774 people, among them 718 children 1-14 years old. Out of them 1 364 people were hospitalized. Unlike last year, the predominant etiological agent in those outbreaks were zoonotic Salmonella serotypes which caused 38.1% outbreaks and 26.7% outbreak cases. The viruses have caused 27.1% of outbreaks and 36.2% of cases. In 23.8% of outbreaks etiological agent has not been established. Most often the settings of an outbreak was a private household - 236 outbreaks and a hospital (84 outbreaks). As in previous years, the most common vehicle of infection were foods prepared with milk and eggs -11.8% of outbreaks and egg dishes - 9.0%. In 57.6% of oubreaks vehicle of infection has not been established. Among outbreaks reported in 2012, there were 4 which involved more than 100 people. In 163 outbreaks of food items had been tested and in 33% of them the results were positive. The increasing negative results of bacteriological examinations of food items, suggested necessity to start testing food contamination with viruses.

Background Globally, Médecins Sans Frontières (MSF) treats more than 300,000 severely malnourished children annually. Malnutrition is not only caused by lack of food and poor infant and child feeding practices but also by illnesses. Breaking the vicious cycle of illness and malnutrition by providing ill children with nutritional supplementation is a potentially powerful strategy for preventing malnutrition that has not been adequately investigated. Therefore, MSF investigated whether incidence of malnutrition among ill children malnutrition rates. Methods and Findings We investigated the effect of supplementation with ready-to-use therapeutic food (RUTF) and a micronutrient powder (MNP) on the incidence of malnutrition in ill children presenting at an outpatient clinic in Goronyo during February to September 2012. A three-armed, partially-blinded, randomised controlled trial was conducted in children diagnosed as having malaria, diarrhoea, or lower respiratory tract infection. Children aged 6 to 59 mo were randomised to one of three arms: one sachet/d of RUTF; two sachets/d of micronutrients or no supplement (control) for 14 d for each illness over 6 mo. The primary outcome was the incidence of first negative nutritional outcome (NNO) during the 6 mo follow-up. NNO was a study-specific measure used to indicate occurrence of malnutrition; it was defined as low weight-for-height z-score (malnutrition. The lack of effect in Goronyo may be due to a high frequency of morbidity, which probably further affects a child’s nutritional status and children’s ability to escape from the illness–malnutrition cycle. The duration of the supplementation may have been too short or the doses of the supplements may have been too low to mitigate the effects of high morbidity and pre-existing malnutrition. An integrated approach combining prevention and treatment of diseases and treatment of moderate malnutrition, rather than prevention of malnutrition by nutritional

Beside food control according to the concept "from the farm to the table" there is increased need for the development of new technology for longer shelf lifes of food. Food fermented by lactic acid bacteria (LAB and traditionally considered to be safe. There are many substances produced by LAB that affect the shelf life of fermented food, by active suppression of poisoning microorganisms growth. Because of that, the LAB is recently considered as bioprotective agents that have important role in food safety.

To assess the efficacy of diazepam suppositories at preventing febrile seizure recurrence during a single febrile illness to determine how to treat children with a febrile seizure on presentation at the hospital. We studied 203 children with febrile seizures from December 2004 through March 2006. On admission between December 2004 and May 2005, a diazepam suppository was administered to the patients. Patients seen between June 2005 and March 2006 were not treated with antiepileptic drugs on admission. We saw a significant difference in the rate of recurrence of febrile seizures between children treated with diazepam and those who were not. Recurrences were observed in 2 (2.1%) of 95 children treated with diazepam and in 16 (14.8%) of 108 untreated children. For the 108 untreated patients, the median age was 22.8 months in those with recurrences and 30.6 months in those without, confirming that a younger age was related to a recurrence. A diazepam suppository after a febrile seizure will reduce the incidence of recurrent febrile seizures during the same febrile illness. However, a diazepam suppository after a febrile seizure should be used after carefully considering the benefits and potential adverse effects.

Bacterial foodborne pathogens are a significant health burden and the recent emergence of pathogenic resistant strains due to the excessive use of antibiotics makes it more difficult to effectively treat infections as a result of contaminated food. Awareness of this impending health crisis has spurred the search for alternative antimicrobials with natural plant antimicrobials being among the more promising candidates as these substances have good acceptability and likely low toxicity levels as they have long been used in traditional medicines. Resveratrol (3,5,4′-trihydroxystilbene) is a naturally occurring stilbenoid which has been gaining considerable attention in medical field due to its diverse biological activities - it has been reported to exhibit antioxidant, cardioprotective, anti-diabetic, anticancer, and antiaging properties. Given that resveratrol is phytoalexin, with increased synthesis in response to infection by phytopathogens, there has been interest in exploring its antimicrobial activity. This review aims to provide an overview of the published data on the antibacterial activity of resveratrol against foodborne pathogens, its mechanisms of action as well as its possible applications in food packing and processing; in addition we also summarize the current data on its potential synergism with known antibacterials and future research and applications.

Full Text Available Microbiological analysis of food is an integrated part of microbial safety management in the food chain. Monitoring and controlling foodborne pathogens are traditionally carried out by conventional microbiological methods based on culture-dependent approaches in control laboratories and private companies. However, polymerase chain reaction (PCR has revolutionized microbiological analysis allowing detection of pathogenic microorganisms in food, without the necessity of classical isolation and identification. However, at present, PCR and quantitative polymerase chain reaction (qPCR are essential analytical tools for researchers working in the field of foodborne pathogens. This manuscript reviews recently described qPCR methods applied for foodborne bacteria detection, serving as economical, safe, and reliable alternatives for application in the food industry and control laboratories. Multiplex qPCR, which allows the simultaneous detection of more than one pathogen in one single reaction, saving considerable effort, time, and money, is emphasized in the article.

Foodborne disease outbreaks are one of the main health problems all over the world, which have an extensive impact on human health. [corrected] To analyze the foodborne disease outbreaks occurred in Chilean urban area from 2005 to 2010. We made a descriptive epidemiologic study. First, criteria were defined and classified according to previous epidemiologic investigations, clinical and environment samples, then. Variables of space, time, place and person were also analyzed. Among 2,806 reported outbreaks, 2434 (86.7%) fulfilled the inclusion criteria. Incidence rate of the period (2005-2010) were 32 cases per 100 inhabitants. A total of 12,196 people were affected, with an average of 5 patients per outbreak. The households (36.2%), restaurants (16.3%), supermarkets (6.3%) free fair (4.4%) have been the most important outbreak areas. The foods involved were seafood (15.4%), fish (15.1%), and fast food (13.5%). The etiologic agents were Salmonella spp, Shigella spp, Vibrio parahaemolyticus. Outbreaks foodborne diseases are frequents in the Chilean urban area, which make vulnerable a lot of people. The largest numbers happened in the households and were due to bad handling and/or inappropriate storage of the foods.

Epigenetic basis of sensitization to stress, affective episodes, and stimulants: implications for illness progression and prevention.

Science.gov (United States)

Post, Robert M

2016-06-01

The process of sensitization (increased responsivity) to the recurrence of stressors, affective episodes, and bouts of substance abuse that can drive illness progression in the recurrent affective disorders requires a memory of and increased reactivity to the prior exposures. A wealth of studies now supports the postulate that epigenetic mechanisms underlie both normal and pathological memory processes. We selectively reviewed the literature pertinent to the role of epigenetics in behavioral sensitization phenomena and discuss its clinical implications. Epigenetics means above genetics and refers to environmental effects on the chemistry of DNA, histones (around which DNA is wound), and microRNA that change how easily genes are turned on and off. The evidence supports that sensitization to repeated stressor, affective episodes, and substance is likely based on epigenetic mechanisms and that these environmentally based processes can then become targets for prevention, early intervention, and ongoing treatment. Sensitization processes are remediable or preventable risk factors for a poor illness outcome and deserve increased clinical, public health, and research attention in the hopes of making the recurrent unipolar and bipolar affective disorders less impairing, disabling, and lethal by suicide and increased medical mortality. The findings that epigenetic chemical marks, which change in the most fundamental way how genes are regulated, mediate the long-term increased responsivity to recurrent stressors, mood episodes, and bouts of substance abuse should help change how the affective disorders are conceptualized and move treatment toward earlier, more comprehensive, and sustained pharmacoprophylaxis. © 2016 John Wiley & Sons A/S.

Abstract The Injury and Illness Prevention Program (IIPP) requirement has been the most frequently cited standard in California workplace health and safety inspections almost every year since it became effective in July 1991. Every workplace safety inspection must assess compliance with the IIPP. This article presents the results of an evaluation of the IIPP's effects on worker injuries in California and should inform policy both in California and in the federal Occupational Safety and Health Administration (OSHA) program, which has made the adoption of a similar national requirement a top priority. Using data from the Workers' Compensation Information System, OSHA Data Initiative statistics, and Workers' Compensation Insurance Rating Bureau of California reports on medical and indemnity claims from single-establishment firms, the evaluation team analyzed the impact of citations for violations of the IIPP on safety performance by (1) using the number of citations as a measure of effectiveness and (2) assessing the number of establishments that were cited for noncompliance and then came into compliance. They found that enforcement of the IIPP appears to prevent injuries only when inspectors cite firms for violations of specific subsections of that standard. Eighty percent of the citations of the IIPP by the California Division of Occupational Safety and Health program are for only a different section, the one that requires employers to have a written IIPP. The specific subsections refer to the provisions that mandate surveying and fixing hazards, investigating the causes of injuries, and training employees to work safely. Because about 25 percent of all inspections cite the IIPP, citations of the specific subsections occur in about 5 percent of all inspections. In those inspections, the total recordable injury rate falls by more than 20 percent in the two years following the inspection. PMID:28083238

Children aged 6 to 59 mo were randomised to one of three arms: one sachet/d of RUTF; two sachets/d of micronutrients or no supplement (control) for 14 d for each illness over 6 mo. The primary outcome was the incidence of first negative nutritional outcome (NNO) during the 6 mo follow-up. NNO was a study-specific measure used to indicate occurrence of malnutrition; it was defined as low weight-for-height z-score (children), mid-upper arm circumference children who were moderately malnourished compared with non-malnourished at enrollment. The average number of study illnesses for the RUTF, MNP, and control groups were 4.2 (95% CI, 4.0-4.3), 3.4 (3.2-3.6), and 3.6 (3.4-3.7). The proportion of children who died in the RUTF, MNP, and control groups were 0.8% (95% CI, 0.3-1.8), 1.8% (1.0-3.3), and 1.4% (0.7-2.8). A 2-wk supplementation with RUTF or MNP to ill children as part of routine primary medical care did not reduce the incidence of malnutrition. The lack of effect in Goronyo may be due to a high frequency of morbidity

The California heat illness prevention study (CHIPS) devised methodology and collected physiological data to assess heat related illness (HRI) risk in Latino farmworkers. Bilingual researchers monitored HRI across a workshift, recording core temperature, work rate (metabolic equivalents [METs]), and heart rate at minute intervals. Hydration status was assessed by changes in weight and blood osmolality. Personal data loggers and a weather station measured exposure to heat. Interviewer administered questionnaires were used to collect demographic and occupational information. California farmworkers (n = 588) were assessed. Acceptable quality data was obtained from 80% of participants (core temperature) to 100% of participants (weight change). Workers (8.3%) experienced a core body temperature more than or equal to 38.5 °C and 11.8% experienced dehydration (lost more than 1.5% of body weight). Methodology is presented for the first comprehensive physiological assessment of HRI risk in California farmworkers.

Botulism type E intoxication is a rare condition among human botulism. We aim to describe a first case of botulism type E intoxication in Taiwan. We report a 36-year-old young man with foodborne botulism type E associated with commercially vacuum packaged dried bean curd. He developed bilateral ptosis, diplopia and dysphagia 4 days after taking the dried bean curd. Electrophysiologic findings demonstrated waxing responses to 3 Hz repetitive nerve stimulation and decreased compound muscle action potentials on peripheral nerve conduction study. A bioassay for botulism in mice demonstrated that the patient had botulism caused by type E botulinum toxin. Antibodeis to C. botulinum type E were identified from his serum, confirming the diagnosis. This is the first known case of foodborne type E botulism in Taiwan. The potential source of this foodborne botulism should consider contaminated food made of soy beans.

Full Text Available In the last two and a half decades, there have been series of global burden of disease studies which have highlighted significant disability attributable to mental and behavioral disorders with a huge treatment gap. Integration of the preventive strategies in the clinical practice has the potential to reduce the disability due to mental illnesses. The patients come to the clinic with an intention to get treated and investigated for the symptoms they have. At this point, they may also be amenable to the advice related to prevention. Therefore, the clinical encounter can be seen as an opportunity to implement preventive strategies. Preventive efforts in clinical practice must be guided by knowledge about the epidemiological data related to specific mental illnesses and about the evidence-based preventive strategies available for specific mental illnesses. These should be directed toward all those persons (patients, caregivers accompanying and at home, teachers, employers, etc. who are present and also toward those who are not present during the clinical encounter and must be age, gender, and culture sensitive. Sociodemographic characteristics of a person seeking relief from a problem in the clinical encounter help in directing the preventive efforts. The preventive efforts are also driven by the fact that the patient has the first episode or established or treatment refractory mental illness and the short or long duration of illness. For prevention-minded clinical practice, it helps to have a template so that the assessments and interventions relevant for prevention can be carried out as per that scheme; it also helps in orienting the practicing mental health professionals. While making various assessments, making a list of the likely issues to be addressed by preventive efforts during clinical encounter ( first and subsequent is also helpful.

Full Text Available Introduction:Food-borne diseases are the widespread problems worldwide. Campylobacter species are the most important pathogens causing gastroenteritis which is generally transmitted through the food with animal origin. The aim of this study was to identify the Campylobacter spp. in diarrheal outbreaks in food-borne diseases at country level. Methods:This cross-sectional study carried out in spring and summer, 2015. In total, 305 swabs from diarrheal stool samples of 102 food-borne outbreaks were collected in various provinces of Iran. All samples were examined for the presence and growth of Campylobacter spp. The descriptive analysis, chi-square test and SPSS v.21 software were used for the analysis of results. Results:From the total of 102 foodborne outbreaks, Zanjan Province with 24 outbreaks (24.5% and Yazd Province with 70 samples of diarrhea (23% included the most reported cases. Out of 305 tested samples, 119 (39% were from food, 35 (11.5% from water and 151 (41.5% from unknown sources (p <0.001.  Two outbreaks in Yazd Province including three stool samples contained Campylobacter coli. Typical symptoms included diarrhea (30.9%, abdominal cramps (68.5%, fever (31.8%, headache (42.3%, diarrhea (5.2%, nausea (62.3% and vomiting (64.9%. Conclusion:Results from this study showed that C. coli was responsible for diarrhea rather than C. jejuni.

Prevention of suicide

Full Text Available Suicide is a major public health problem in India, probably even bigger than in the West. Suicidal behavior is the best conceptualized as a multifaceted complex problem involving social factors and mental illnesses. Broadly, there are two approaches to suicide prevention; population preventive strategies and high-risk preventive strategies. Population preventive strategies include reducing availability of means for suicide, education of primary care physicians, influencing media portrayal of suicidal behavior, education of the public, telephone helplines, and addressing economic issues associated with suicidal behavior. High-risk preventive strategy includes identifying individuals with high risk of committing suicide, intensively treating mental illness if present, and providing psychosocial support. Thus, prevention requires a multipronged effort with collaboration from various sectors including mental health professionals, social justice department, and macroeconomic policy makers.

The role of meat in foodborne disease: Is there a coming revolution in risk assessment and management?

Science.gov (United States)

Fegan, Narelle; Jenson, Ian

2018-04-20

Meat has featured prominently as a source of foodborne disease and a public health concern. For about the past 20 years the risk management paradigm has dominated international thinking about food safety. Control through the supply chain is supported by risk management concepts, as the public health risk at the point of consumption becomes the accepted outcome based measure. Foodborne pathogens can be detected at several points in the supply chain and determining the source of where these pathogens arise and how they behave throughout meat production and processing are important parts of risk based approaches. Recent improvements in molecular and genetic based technologies and data analysis for investigating source attribution and pathogen behaviour have enabled greater insights into how foodborne outbreaks occur and where controls can be implemented. These new approaches will improve our understanding of the role of meat in foodborne disease and are expected to have a significant impact on our understanding in the coming years.

Zhao, Xihong; Zhong, Junliang; Wei, Caijiao; Lin, Chii-Wann; Ding, Tian

2017-01-01

The viable but non-culturable (VBNC) state, a unique state in which a number of bacteria respond to adverse circumstances, was first discovered in 1982. Unfortunately, it has been reported that many foodborne pathogens can be induced to enter the VBNC state by the limiting environmental conditions during food processing and preservation, such as extreme temperatures, drying, irradiation, pulsed electric field, and high pressure stress, as well as the addition of preservatives and disinfectants. After entering the VBNC state, foodborne pathogens will introduce a serious crisis to food safety and public health because they cannot be detected using conventional plate counting techniques. This review provides an overview of the various features of the VBNC state, including the biological characteristics, induction and resuscitation factors, formation and resuscitation mechanisms, detection methods, and relationship to food safety.

Outbreaks where food workers have been implicated in the spread of foodborne disease. Part 4. Infective doses and pathogen carriage.

Todd, Ewen C D; Greig, Judy D; Bartleson, Charles A; Michaels, Barry S

2008-11-01

In this article, the fourth in a series reviewing the role of food workers in foodborne outbreaks, background information on the presence of enteric pathogens in the community, the numbers of organisms required to initiate an infection, and the length of carriage are presented. Although workers have been implicated in outbreaks, they were not always aware of their infections, either because they were in the prodromic phase before symptoms began or because they were asymptomatic carriers. Pathogens of fecal, nose or throat, and skin origin are most likely to be transmitted by the hands, highlighting the need for effective hand hygiene and other barriers to pathogen contamination, such as no bare hand contact with ready-to-eat food. The pathogens most likely to be transmitted by food workers are norovirus, hepatitis A virus, Salmonella, Shigella, and Staphylococcus aureus. However, other pathogens have been implicated in worker-associated outbreaks or have the potential to be implicated. In this study, the likelihood of pathogen involvement in foodborne outbreaks where infected workers have been implicated was examined, based on infectious dose, carriage rate in the community, duration of illness, and length of pathogen excretion. Infectious dose estimates are based on volunteer studies (mostly early experiments) or data from outbreaks. Although there is considerable uncertainty associated with these data, some pathogens appear to be able to infect at doses as low as 1 to 100 units, including viruses, parasites, and some bacteria. Lengthy postsymptomatic shedding periods and excretion by asymptomatic individuals of many enteric pathogens is an important issue for the hygienic management of food workers.

The Olympic Movement Medical Code encourages all stakeholders to ensure that sport is practised without danger to the health of the athletes. Systematic surveillance of injuries and illnesses is the foundation for developing preventive measures in sport. To analyse the injuries and illnesses that occurred during the Games of the XXX Olympiad, held in London in 2012. We recorded the daily occurrence (or non-occurrence) of injuries and illnesses (1) through the reporting of all National Olympic Committee (NOC) medical teams and (2) in the polyclinic and medical venues by the London Organising Committee of the Olympic and Paralympic Games' (LOCOG) medical staff. In total, 10 568 athletes (4676 women and 5892 men) from 204 NOCs participated in the study. NOC and LOCOG medical staff reported 1361 injuries and 758 illnesses, equalling incidences of 128.8 injuries and 71.7 illnesses per 1000 athletes. Altogether, 11% and 7% of the athletes incurred at least one injury or illness, respectively. The risk of an athlete being injured was the highest in taekwondo, football, BMX, handball, mountain bike, athletics, weightlifting, hockey and badminton, and the lowest in archery, canoe slalom and sprint, track cycling, rowing, shooting and equestrian. 35% of the injuries were expected to prevent the athlete from participating during competition or training. Women suffered 60% more illnesses than men (86.0 vs 53.3 illnesses per 1000 athletes). The rate of illness was the highest in athletics, beach volleyball, football, sailing, synchronised swimming and taekwondo. A total of 310 illnesses (41%) affected the respiratory system and the most common cause of illness was infection (n=347, 46%). At least 11% of the athletes incurred an injury during the games and 7% of the athletes' an illness. The incidence of injuries and illnesses varied substantially among sports. Future initiatives should include the development of preventive measures tailored for each specific sport and the

The U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS) works closely with federal, state, and local public health partners to investigate foodborne illness outbreaks associated with its regulated products. To provide insight into outbreaks associated with meat and poultry, outbreaks reported to FSIS during fiscal years 2007 through 2012 were evaluated. Outbreaks were classified according to the strength of evidence linking them to an FSIS-regulated product and by their epidemiological, etiological, and vehicle characteristics. Differences in outbreak characteristics between the period 2007 through 2009 and the period 2010 through 2012 were assessed using a chi-square test or Mann-Whitney U test. Of the 163 reported outbreaks eligible for analysis, 89 (55%) were identified as possibly linked to FSIS-regulated products and 74 (45%) were definitively linked to FSIS-regulated products. Overall, these outbreaks were associated with 4,132 illnesses, 772 hospitalizations, and 19 deaths. Shiga toxin-producing Escherichia coli was associated with the greatest proportion of reported outbreaks (55%), followed by Salmonella enterica (34%) and Listeria monocytogenes (7%). Meat and poultry products commercially sold as raw were linked to 125 (77%) outbreaks, and of these, 105 (80%) involved beef. Over the study period, the number of reported outbreaks definitively linked to FSIS-regulated products (P = 0.03) declined, while the proportion of culture-confirmed cases (P = 0.0001) increased. Our findings provide insight into the characteristics of outbreaks associated with meat and poultry products.

National Studies as a Component of the World Health Organization Initiative to Estimate the Global and Regional Burden of Foodborne Disease.

Directory of Open Access Journals (Sweden)

Robin J Lake

Full Text Available The World Health Organization (WHO initiative to estimate the global burden of foodborne diseases established the Foodborne Diseases Burden Epidemiology Reference Group (FERG in 2007. In addition to global and regional estimates, the initiative sought to promote actions at a national level. This involved capacity building through national foodborne disease burden studies, and encouragement of the use of burden information in setting evidence-informed policies. To address these objectives a FERG Country Studies Task Force was established and has developed a suite of tools and resources to facilitate national burden of foodborne disease studies. This paper describes the process and lessons learned during the conduct of pilot country studies under the WHO FERG initiative.Pilot country studies were initiated in Albania, Japan and Thailand in 2011 and in Uganda in 2012. A brief description of each study is provided. The major scientific issue is a lack of data, particularly in relation to disease etiology, and attribution of disease burden to foodborne transmission. Situation analysis, knowledge translation, and risk communication to achieve evidence-informed policies require specialist expertise and resources.The FERG global and regional burden estimates will greatly enhance the ability of individual countries to fill data gaps and generate national estimates to support efforts to reduce the burden of foodborne disease.

Physical Health Risk Behaviours in Young People with Mental Illness.

2015-01-01

Comorbid physical health conditions, commonly associated with mental illness, contribute to increased morbidity and reduced life expectancy. The trajectory to poorer health begins with the onset of mental illness. For young people with mental illness, health risk behaviours and poor physical health can progress to adulthood with long-term detrimental impacts. Using a cross-sectional survey design, self-reported health risk behaviours were gathered from 56 young (16-25 years) Australians who had been hospitalised for mental illness and taking psychotropic medication. Smoking, alcohol use, minimal physical activity, and lack of primary health care were evident. While these behaviours are typical of many young people, those with mental illness have substantially increased vulnerability to poor health and reduced life expectancy. Priority needs to be given to targeted health promotion strategies for young people with mental illness to modify their risky long-term health behaviours and improve morbidity and mortality outcomes. Nurses in mental health settings play a vital role in promoting young peoples' well-being and preventing poorer physical health outcomes. Implementation of a cardiometabolic health nurse role in inpatient settings for young people with mental illness could facilitate prevention and early intervention for health risk behaviours.

To summarize the current literature on racial and gender disparities in critical care and the mechanisms underlying these disparities in the course of acute critical illness. MEDLINE search on the published literature addressing racial, ethnic, or gender disparities in acute critical illness, such as sepsis, acute lung injury, pneumonia, venous thromboembolism, and cardiac arrest. Clinical studies that evaluated general critically ill patient populations in the United States as well as specific critical care conditions were reviewed with a focus on studies evaluating factors and contributors to health disparities. Study findings are presented according to their association with the prevalence, clinical presentation, management, and outcomes in acute critical illness. This review presents potential contributors for racial and gender disparities related to genetic susceptibility, comorbidities, preventive health services, socioeconomic factors, cultural differences, and access to care. The data are organized along the course of acute critical illness. The literature to date shows that disparities in critical care are most likely multifactorial involving individual, community, and hospital-level factors at several points in the continuum of acute critical illness. The data presented identify potential targets as interventions to reduce disparities in critical care and future avenues for research.

Gun policy and serious mental illness: priorities for future research and policy.

McGinty, Emma Elizabeth; Webster, Daniel W; Barry, Colleen L

2014-01-01

In response to recent mass shootings, policy makers have proposed multiple policies to prevent persons with serious mental illness from having guns. The political debate about these proposals is often uninformed by research. To address this gap, this review article summarizes the research related to gun restriction policies that focus on serious mental illness. Gun restriction policies were identified by researching the THOMAS legislative database, state legislative databases, prior review articles, and the news media. PubMed, PsycINFO, and Web of Science databases were searched for publications between 1970 and 2013 that addressed the relationship between serious mental illness and violence, the effectiveness of gun policies focused on serious mental illness, the potential for such policies to exacerbate negative public attitudes, and the potential for gun restriction policies to deter mental health treatment seeking. Limited research suggests that federal law restricting gun possession by persons with serious mental illness may prevent gun violence from this population. Promotion of policies to prevent persons with serious mental illness from having guns does not seem to exacerbate negative public attitudes toward this group. Little is known about how restricting gun possession among persons with serious mental illness affects suicide risk or mental health treatment seeking. Future studies should examine how gun restriction policies for serious mental illness affect suicide, how such policies are implemented by states, how persons with serious mental illness perceive policies that restrict their possession of guns, and how gun restriction policies influence mental health treatment seeking among persons with serious mental illness.

A European network for food-borne parasites (Euro-FBP: meeting report on ‘Analytical methods for food-borne parasites in human and veterinary diagnostics and in food matrices’

Directory of Open Access Journals (Sweden)

Christian Klotz

2017-11-01

Full Text Available Abstract Food-borne parasites (FBPs are a neglected topic in food safety, partly due to a lack of awareness of their importance for public health, especially as symptoms tend not to develop immediately after exposure. In addition, methodological difficulties with both diagnosis in infected patients and detection in food matrices result in under-detection and therefore the potential for underestimation of their burden on our societies. This, in consequence, leads to lower prioritization for basic research, e.g. for development new and more advanced detection methods for different food matrices and diagnostic samples, and thus a vicious circle of neglect and lack of progress is propagated. The COST Action FA1408, A European Network for Foodborne Parasites (Euro-FBP aims to combat the impact of FBP on public health by facilitating the multidisciplinary cooperation and partnership between groups of researchers and between researchers and stakeholders. The COST Action TD1302, the European Network for cysticercosis/taeniosis, CYSTINET, has a specific focus on Taenia solium and T. saginata, two neglected FBPs, and aims to advance knowledge and understanding of these zoonotic disease complexes via collaborations in a multidisciplinary scientific network. This report summarizes the results of a meeting within the Euro-FBP consortium entitled ‘Analytical methods for food-borne parasites in human and veterinary diagnostics and in food matrices’ and of the joined Euro-FBP and CYSTINET meeting.

2013-10-24

Heat-related illness (HRI) is an important cause of non-fatal illness and death in farmworkers. We sought to identify potential barriers to HRI prevention and treatment in Latino farmworkers. We conducted three semi-structured focus group discussions with 35 Latino farmworkers in the Central Washington, USA area using participatory rural appraisal techniques. Interviews were audio taped and transcribed in Spanish. Three researchers reviewed and coded transcripts and field notes, and investigator triangulation was used to identify relevant themes and quotes. Although the majority of participants in our study reported never receiving formal HRI training, most participants were aware that extreme heat can cause illness and were able to accurately describe HRI symptoms, risk factors, and certain prevention strategies. Four main observations regarding farmworkers' HRI-relevant beliefs and attitudes were identified: 1) farmworkers subscribe to varying degrees to the belief that cooling treatments should be avoided after heat exposure, with some believing that such treatments should be avoided after heat exposure, and others encouraging the use of such treatments; 2) the desire to lose weight may be reflected in behaviors that promote increased sweating; 3) highly caffeinated energy drinks are preferred to increase work efficiency and maintain alertness; and 4) the location of drinking water at work (e.g. next to restrooms) and whether water is clean, but not necessarily chemically-treated, are important considerations in deciding whether to drink the water provided at worksites. We identified potential barriers to HRI prevention and treatment related to hydration, certain HRI treatments, clothing use, and the desire to lose weight among Latino farmworkers. Strategies to address potential barriers to HRI prevention and treatment in this population may include engineering, administrative, and health education and health promotion strategies at individual, workplace

High Throughput Sequencing for Detection of Foodborne Pathogens

2017-10-01

Full Text Available High-throughput sequencing (HTS is becoming the state-of-the-art technology for typing of microbial isolates, especially in clinical samples. Yet, its application is still in its infancy for monitoring and outbreak investigations of foods. Here we review the published literature, covering not only bacterial but also viral and Eukaryote food pathogens, to assess the status and potential of HTS implementation to inform stakeholders, improve food safety and reduce outbreak impacts. The developments in sequencing technology and bioinformatics have outpaced the capacity to analyze and interpret the sequence data. The influence of sample processing, nucleic acid extraction and purification, harmonized protocols for generation and interpretation of data, and properly annotated and curated reference databases including non-pathogenic “natural” strains are other major obstacles to the realization of the full potential of HTS in analytical food surveillance, epidemiological and outbreak investigations, and in complementing preventive approaches for the control and management of foodborne pathogens. Despite significant obstacles, the achieved progress in capacity and broadening of the application range over the last decade is impressive and unprecedented, as illustrated with the chosen examples from the literature. Large consortia, often with broad international participation, are making coordinated efforts to cope with many of the mentioned obstacles. Further rapid progress can therefore be prospected for the next decade.

Resisting "Reason": A Comparative Anthropological Study of Social Differences and Resistance toward Health Promotion and Illness Prevention in Denmark.

2017-06-01

Social differences in health and illness are well documented in Denmark. However, little is known about how health practices are manifested in the everyday lives of different social classes. We propose acts of resistance and formation of health subjectivities as helpful concepts to develop our understanding of how dominant health discourses are appropriated by different social classes and transformed into different practices promoting health and preventing illness. Based on fieldwork in two different social classes, we discuss how these practices both overtly and subtly challenge the normative power of the health promotion discourse. These diverse and ambiguous forms of everyday resistance illustrate how and when situated concerns move social actors to subjectively appropriate health promotion messages. Overall, the different forms of resistance elucidate how the standardized awareness and education campaigns may perpetuate the very inequalities they try to diminish. © 2016 by the American Anthropological Association.

The information of this fish food-borne poisoning is part of student’s education in discipline “Marine medicine” in Medical University, Varna. Materials and methods: To present better information from different authors and last scientific data, we made review of published materials of 58 issues to construct definition, history, etiology, pathogenesis (toxins and mechanisms of action, clinical symptoms, treatment and prevention of the Ciguatera or ichtyosarcotoxicosis, a wide spread food-born poisoning. Results: Ciguatera poisoning is ichtyosarcotoxicosis, a wide-spread foodborne poisoning in people after consumption of flesh of different kinds of fishes in which toxins produced by poisonous microorganisms (Dinoflagellates have accumulated. The poisoning develops by accumulating toxins higher up the food chain starting with toxin producing dinoflagellates (species: Gambierdiscus toxicus, Prorocentrum concavum, Pr. lima, Ostreoposis lenticularis, Ostr. Siamensis and others, continuing with the poisoned algae (species: Portieria, Halymenia, Turbinaria, Sargassum, and after that involving small crustacea and small fishes to greater fishes (vector fishes, genus Herbivores and Carnivores, in which the toxins have been stored in amount, great enough to cause foodborne poisoning in humans. This poisoning is widespread in tropical and subtropical regions, but because of its delayed toxic effects, lasting

Full Text Available Rubber is one of the important commodities in the world. Globally, workers are facing so many problems of hazards that produce by rubber process. In Indonesia, there are several data of occupational problems such as respiratory diseases, muscle and skeletal diseases, gastrointestinal diseases, diseases of the teeth and oral cavity, skin diseases and skin tissue. In Iranian rubber factory, Iran, workers had suffered from some kind of musculoskeletal symptoms. Stomach and liver cancers in workers are having in Shanghai tire factory. In addition, Germany has cancer problem of their workers who work in rubber factory. Most of the rubber process in the factory can cause some hazards of the workers. In unloading area and area that operator is taking the dirt manually, workers are facing ergonomic problems. The possible control is reduce weight of load, team lift the object with two or more workers and Use mechanical assist. Machine safeguarding is essential for protecting from Cutting process that can make workers amputation organs such as hands, and fingers. In bale process, the workers need to cut raw rubber into bale in bale cutting. Furthermore, workers are facing with amputation problem. To manage that, It must be designed as a standard which has interlocking guards to prevent access to the cutting area. When wrapped using plastic, workers use a heated iron and sticked in plastic so that it blends neatly. The risks are fingers can cut accidently and then the workers also get contamination from polyvinyl chloride (PVC. The possible preventions are use an automatic plastic wrapping machine with palletized product sitting on a turntable and respirator. Another problem is contact dermatitis that has been reported frequently among rubber workers. The prevention for that problem is using Gloves. The aim of researcher is to provide the profile of occupational injuries and illnesses, potential hazards in rubber factory to prevent the workers.

Prevention of influenza-related illness in young infants by maternal vaccination during pregnancy [version 1; referees: 2 approved

Full Text Available The influenza virus circulates yearly and causes global epidemics. Influenza infection affects all age groups and causes mild to severe illness, and young infants are at particular risk for serious disease. The most effective measure to prevent influenza disease is vaccination; however, no vaccine is licensed for use in infants younger than 6 months old. Thus, there is a crucial need for other preventive strategies in this high-risk age group. Influenza vaccination during pregnancy protects both the mothers and the young infants against influenza infection. Vaccination during pregnancy boosts the maternal antibodies and increases the transfer of immunoglobulin G from the mother to the fetus through the placenta, which confers protection against infection in infants too young to be vaccinated. Data from clinical trials and observational studies did not demonstrate adverse effects to the mother, the fetus, or the infant after maternal influenza vaccination. We present the current data on the effectiveness and safety of influenza vaccination during pregnancy in preventing disease in the young infant.

Fatigue at work: Professional illness of the 21th century: Prevention and consequences

Full Text Available Psychophysical capabilities of individuals in terms of work in the modern systems of today are not the only factor that their performance and achievement of results depend on. The context is much broader, starting from work conditions at their work place, through physical and climate factors, social environment and support, down to psychophysical status of an individual, his/her general work efficiency and risk from getting professional illnesses. Although the mechanisms and causes of fatigue occurring at work have long been a subject of study and interest in the area of psychophysiology of work, the fact is that to the day there has been no unique and generally accepted definition of fatigue, not only due to complex causes of its origin, but also due to complexity and diversity of its manifestations. Factors that are subject of study may be grouped into areas of contents of work, organization of work or work environment, and they significantly affect working ability and its misbalance, needs, capabilities and requirements to be met by an individual at a work place. Similarly to the concept of stress at work, fatigue as a reversible physiological occurrence manifests itself in physiological, i.e. health-related, psychological and professional areas, which in the long run affects total performance and efficiency of an individual, and results in unfit behavior, mental problems or physical illness. Keeping this in mind, it is important that a professional department and personnel management in organizations and institutions should react in a timely manner in order to prevent, detect and eliminate the factors that bring an individual at work to chronicle fatigue, therefore, to reduced performance and productivity at work.

The role played by food workers and other individuals in the contamination of food has been identified as an important contributing factor leading to foodborne outbreaks. To prevent direct bare hand contact with food and food surfaces, many jurisdictions have made glove use compulsory for food production and preparation. When properly used, gloves can substantially reduce opportunities for food contamination. However, gloves have limitations and may become a source of contamination if they are punctured or improperly used. Experiments conducted in clinical and dental settings have revealed pinhole leaks in gloves. Although such loss of glove integrity can lead to contamination of foods and surfaces, in the food industry improper use of gloves is more likely than leakage to lead to food contamination and outbreaks. Wearing jewelry (e.g., rings) and artificial nails is discouraged because these items can puncture gloves and allow accumulation of microbial populations under them. Occlusion of the skin during long-term glove use in food operations creates the warm, moist conditions necessary for microbial proliferation and can increase pathogen transfer onto foods through leaks or exposed skin or during glove removal. The most important issue is that glove use can create a false sense of security, resulting in more high-risk behaviors that can lead to cross-contamination when employees are not adequately trained.

Full Text Available OBJECTIVES Recently kudoa septempuctata in olive flounders is suggested as a cause of food poisoning, however whether kudoa septempuctata can affect human gastrointestinal systems is controversial and its pathogenecity remains unclear. In view of the field epidemiology, food poisonings caused by kudoa septempuctata should be distinguished from those caused by Staphylococcus aureus and bacillus cereus. METHODS The statistics of food poisoning investigations published by Korea Centers for Disease Control and Prevention in 2013-2015 were reviewed. The characteristics of kudoa septempuctata food poisoning reported by Korea Centers for Disease Control and Prevention were reviewed. Information regarding clinical symptoms or epidemiology was extracted. RESULTS Total eleven kudoa septempuctata food poisoning cases were analyzed. Food poisonings caused by kudoa septempuctata, Staphylococcus aureus and bacillus cereus have clinical and epidemiological similarities. Forty five percent of food poisoning outbreaks occurred in Korea was concluded as unknown. The food poisoning caused by Staphylococcus aureus and bacillus cereus accounted for 4.5% (50/1,092 of all food poisoning outbreaks in Korea between 2013 and 2015. CONCLUSIONS This study suggests the possibilities of misdiagnosis in the investigations of food poisoning by Staphylococcus aureus and bacillus cereus with kudoa septempuctata.

Mental illnesses affect many people around the world, either directly or indirectly. Families of persons suffering from mental illness or addiction suffer too, especially their children. In the Netherlands, 864,000 parents meet the diagnostic criteria for a mental illness or addiction. Evidence shows that offspring of mentally ill or addicted parents are at risk for developing mental disorders or illnesses themselves. The Kopstoring course is an online 8-week group course with supervision by 2 trained psychologists or social workers, aimed to prevent behavioral and psychological problems for children (aged 16 to 25 years) of parents with mental health problems or addictions. The course addresses themes such as roles in the family and mastery skills. An online randomized controlled trial (RCT) was conducted to assess the effectiveness of the Kopstoring course. The aim was to gain knowledge about expectations, experiences, and perspectives of participants and providers of the online Kopstoring course. A process evaluation was performed to evaluate the online delivery of Kopstoring and the experiences and perspectives of participants and providers of Kopstoring. Interviews were performed with members from both groups. Participants were drawn from a sample from the Kopstoring RCT. Thirteen participants and 4 providers were interviewed. Five main themes emerged from these interviews: background, the requirements for the intervention, experience with the intervention, technical aspects, and research aspects. Overall, participants and providers found the intervention to be valuable because it was online; therefore, protecting their anonymity was considered a key component. Most barriers existed in the technical sphere. Additional barriers existed with conducting the RCT, namely gathering informed consent and gathering parental consent in the case of minors. This study provides valuable insight into participants' and providers' experiences and expectations with the online

Care management processes (CMPs), tools to improve the efficiency and quality of primary care delivery, are particularly important for low-income patients facing substantial barriers to care. To measure the adoption of CMPs by medical groups, Independent Practice Associations, community clinics, and hospital-based clinics in California's Medicaid program and the factors associated with CMP adoption. Telephone survey of every provider organization with at least 6 primary care physicians and at least 1 Medi-Cal HMO contract, Spring 2003. One hundred twenty-three organizations participated, accounting for 64% of provider organizations serving Medicaid managed care in California. We surveyed 30 measures of CMP use for asthma and diabetes, and for child and adolescent preventive services. The mean number of CMPs used by each organization was 4.5 for asthma and 4.9 for diabetes (of a possible 8). The mean number of CMPs for preventive services was 4.0 for children and 3.5 for adolescents (of a possible 7). Organizations with more extensive involvement in Medi-Cal managed care used more CMPs for chronic illness and preventive service. Community clinics and hospital-based clinics used more CMPs for asthma and diabetes than did Independent Practice Associations (IPAs), and profitable organizations used more CMPs for child and adolescent preventive services than did entities facing severe financial constraints. The use of CMPs by Medicaid HMOs and the presence of external (financial and nonfinancial) incentives for clinical performance were strongly associated with use of care management by provider organizations. Physician and provider organizations heavily involved in California's Medicaid program are extensively engaged in preventive and chronic care management programs.

We conducted a systematic, qualitative review of risk prediction models designed and tested for depression, bipolar disorder, generalized anxiety disorder, posttraumatic stress disorder, and psychotic disorders. Our aim was to understand the current state of research on risk prediction models for these 5 disorders and thus future directions as our field moves toward embracing prediction and prevention. Systematic searches of the entire MEDLINE electronic database were conducted independently by 2 of the authors (from 1960 through 2013) in July 2014 using defined search criteria. Search terms included risk prediction, predictive model, or prediction model combined with depression, bipolar, manic depressive, generalized anxiety, posttraumatic, PTSD, schizophrenia, or psychosis. We identified 268 articles based on the search terms and 3 criteria: published in English, provided empirical data (as opposed to review articles), and presented results pertaining to developing or validating a risk prediction model in which the outcome was the diagnosis of 1 of the 5 aforementioned mental illnesses. We selected 43 original research reports as a final set of articles to be qualitatively reviewed. The 2 independent reviewers abstracted 3 types of data (sample characteristics, variables included in the model, and reported model statistics) and reached consensus regarding any discrepant abstracted information. Twelve reports described models developed for prediction of major depressive disorder, 1 for bipolar disorder, 2 for generalized anxiety disorder, 4 for posttraumatic stress disorder, and 24 for psychotic disorders. Most studies reported on sensitivity, specificity, positive predictive value, negative predictive value, and area under the (receiver operating characteristic) curve. Recent studies demonstrate the feasibility of developing risk prediction models for psychiatric disorders (especially psychotic disorders). The field must now advance by (1) conducting more large

Methicillin-resistant Staphylococcus aureus: a controversial food-borne pathogen.

Sergelidis, D; Angelidis, A S

2017-06-01

Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of severe healthcare-associated (HA) infections. Although during the last decade the incidence of HA invasive infections has dropped, the incidence of community-associated MRSA (CA-MRSA) infections has risen among the general population. Moreover, CA-MRSA, livestock-associated MRSA (LA-MRSA) and HA-MRSA (HA-MRSA) can be found in foods intended for human consumption. Several studies from different geographical areas have reported the presence of enterotoxin genes in several MRSA food isolates. Molecular typing studies have revealed genetic relatedness of these enterotoxigenic isolates with isolates incriminated in human infections. The contamination sources for foods, especially animal-origin foods, may be livestock as well as humans involved in animal husbandry and food-processing. Under favourable environmental conditions for growth and enterotoxin production, enterotoxigenic S. aureus isolates present in foods can cause staphylococcal food poisoning (SFP), irrespective of the contamination origin. Owing to the typically moderate clinical manifestations of SFP, the S. aureus strains responsible for SFP (cases or outbreaks) are frequently either not identified or not further characterized. Antimicrobial susceptibility testing is rarely performed, because administration of antimicrobial therapy is not required in the vast majority of cases. Staphylococcal food poisoning is the result of consumption of foods with preformed enterotoxins. Hence, similar to methicillin-sensitive enterotoxigenic S. aureus, enterotoxigenic MRSA can also act as food-borne pathogens upon favourable conditions for growth and enterotoxin production. The severity of the intoxication is not related to the antimicrobial resistance profile of the causative S. aureus strain and therefore MRSA food-borne outbreaks are not expected to be more severe. This review evaluates the potential of methicillin-resistant Staphylococcus

Critically ill patients are at high risk of developing pressure ulcers (PU), with the sacrum and heels being highly susceptible to pressure injuries. The objective of our study was to evaluate the clinical effectiveness of a new multi-layer, self-adhesive soft silicone foam heel dressing to prevent PU development in trauma and critically ill patients in the intensive care unit (ICU). A cohort of critically ill patients were enrolled at the Royal Melbourne Hospital. Each patient had the multi-layer soft silicone foam dressing applied to each heel on admission to the emergency department. The dressings were retained with a tubular bandage for the duration of the patients' stay in the ICU. The skin under the dressings was examined daily and the dressings were replaced every three days. The comparator for our cohort study was the control group from the recently completed Border Trial. Of the 191 patients in the initial cohort, excluding deaths, loss to follow-up and transfers to another ward, 150 patients were included in the final analysis. There was no difference in key demographic or physiological variables between the cohorts, apart from a longer ICU length of stay for our current cohort. No PUs developed in any of our intervention cohort patients compared with 14 patients in the control cohort (n=152; p<0.001) who developed a total of 19 heel PUs. We conclude, based on our results, that the multi-layer soft silicone foam dressing under investigation was clinically effective in reducing ICU-acquired heel PUs. The findings also support previous research on the clinical effectiveness of multi-layer soft silicone foam dressings for PU prevention in the ICU.

The illness/non-illness model: hypnotherapy for physically ill patients.

Science.gov (United States)

Navon, Shaul

2014-07-01

This article proposes a focused, novel sub-set of the cognitive behavioral therapy approach to hypnotherapy for physically ill patients, based upon the illness/non-illness psychotherapeutic model for physically ill patients. The model is based on three logical rules used in differentiating illness from non-illness: duality, contradiction, and complementarity. The article discusses the use of hypnotic interventions to help physically ill and/or disabled patients distinguish between illness and non-illness in their psychotherapeutic themes and attitudes. Two case studies illustrate that patients in this special population group can be taught to learn the language of change and to use this language to overcome difficult situations. The model suggests a new clinical mode of treatment in which individuals who are physically ill and/or disabled are helped in coping with actual motifs and thoughts related to non-illness or non-disability.

Foodborne toxoplasmosis is a leading cause of foodborne deaths and hospitalization worldwide. The level of exposure to Toxoplasma gondii is influenced by culture and eating habits. There is a scarcity of data about women's knowledge and perception of this disease. The aim of this study was to determine toxoplasmosis knowledge and preventive practices of young childbearing age women in Jordan. A descriptive cross-sectional study recruited a random sample of 1,390 undergraduate university female students and was stratified based on place of residency. About half of students (51.1%) reported having "ever" heard or read about toxoplasmosis, and almost all students (98.6%) had never been tested for toxoplasmosis. Overall, there was a lack of awareness about toxoplasmosis, its risk factors, symptoms, and timing of infection, and preventive practices. High percentages of females reported a high level of hygienic practices related to hand washing after gardening, changing cat litter, and handling raw meat. However, 16.7% of students reported eating raw meat, 26.5% usually eat traditional herbs, and 17.2% drink untreated spring water. This study establishes a baseline for the awareness levels about toxoplasmosis among young women in Jordan. These findings highlight the urgent need for toxoplasmosis awareness and preventive education for childbearing females. An effective education and outreach program should cover important topics concerning risk factors, high-risk foods, and preventive measures against toxoplasmosis.

In March 1999, an outbreak of gastroenteritis occurred affecting 30 day-care centres served by the same caterer. A retrospective cohort study was performed in 13 randomly selected day-care centres to determine the source and mode of transmission. Electron microscopy and PCR were used to verify the diagnosis. The overall attack rate (AR) was 37% (195/524): 30% in children and 62% in adults. Modified by the age of the patient, eating pumpkin salad served on 1 March was associated with becoming an early case (odds ratio = 3.9; 95% confidence interval 1.8-8.8). No significant association was found between food consumption and becoming a late case. The primary food-borne AR was 27% and the secondary AR was 14%. The same genotype of Norwalk-like virus was found in 5 cases and in 1 ill and 1 asymptomatic food-handler. Contamination by 1 of the food-handlers seems the most likely route of spread of the virus and underlines the importance of strict hygienic routines.

Delirium is characterized by acute changes in mental status including inattention, disorganized thinking, and altered level of consciousness, and is highly prevalent in critically ill adults. Delirium has adverse consequences for both patients and the healthcare system; however, at this time, no effective treatment exists. The identification of effective prevention strategies is therefore a clinical and research imperative. An important limitation of previous reviews of delirium prevention is that interventions were considered in isolation and only direct evidence was used. Our systematic review will synthesize all existing data using network meta-analysis, a powerful statistical approach that enables synthesis of both direct and indirect evidence. We will search Ovid MEDLINE, CINAHL, Embase, PsycINFO, and Web of Science from 1980 to March 2016. We will search the PROSPERO registry for protocols and the Cochrane Library for published systematic reviews. We will examine reference lists of pertinent reviews and search grey literature and the International Clinical Trials Registry Platform for unpublished studies and ongoing trials. We will include randomized and quasi-randomized trials of critically ill adults evaluating any pharmacological, non-pharmacological, or multi-component intervention for delirium prevention, administered in or prior to (i.e., peri-operatively) transfer to the ICU. Two authors will independently screen search results and extract data from eligible studies. Risk of bias assessments will be completed on all included studies. To inform our network meta-analysis, we will first conduct conventional pair-wise meta-analyses for primary and secondary outcomes using random-effects models. We will generate our network meta-analysis using a Bayesian framework, assuming a common heterogeneity parameter across all comparisons, and accounting for correlations in multi-arm studies. We will perform analyses using WinBUGS software. This systematic review

Globally, Médecins Sans Frontières (MSF) treats more than 300,000 severely malnourished children annually. Malnutrition is not only caused by lack of food but also by illnesses and by poor infant and child feeding practices. Breaking the vicious cycle of illness and malnutrition by providing ill children with nutritional supplementation is a potentially powerful strategy for preventing malnutrition that has not been adequately investigated. Therefore, MSF investigated whether incidence of malnutrition among ill children malnutrition rate between 8.4% and 11.5% of which 2% to 3% severe malnutrition, more than half (58%) of the population in the district of Kaabong is considered food insecure. We investigated the effect of two types of nutritional supplementation on the incidence of malnutrition in ill children presenting at outpatient clinics during March 2011 to April 2012 in Kaabong, Karamoja region, Uganda, a resource-poor region where malnutrition is a chronic problem for its seminomadic population. A three-armed, partially-blinded, randomised controlled trial was conducted in children diagnosed with malaria, diarrhoea, or lower respiratory tract infection. Non-malnourished children aged 6 to 59 mo were randomised to one of three arms: one sachet/d of ready-to-use therapeutic food (RUTF), two sachets/d of micronutrient powder (MNP), or no supplement (control) for 14 d for each illness over 6 mo. The primary outcome was the incidence of first negative nutritional outcome (NNO) during the 6 mo follow-up. NNO was a study-specific measure used to indicate progression to moderate or severe acute malnutrition; it was defined as weight-for-height z-score children who died in the RUTF, MNP, and control groups were 0%, 0.8%, and 0.4%. The findings apply to ill but not malnourished children and cannot be generalised to a general population including children who are not necessarily ill or who are already malnourished.

Prefectural and municipal public health institutes are located in prefectures and ordinance-designated cities in Japan, and play a vital role in the regional surveillance of infectious diseases and foodborne illnesses. These institutes, in close cooperation with national institutes such as the National Institute of Infectious Diseases and the National Institute of Health Sciences, construct the national surveillance network for infectious diseases and their causative agents. Bacteriological examinations and studies on a variety of infectious diseases and foodborne illnesses are core activities of prefectural and municipal public health institutes, through which novel and important bacteriological findings have been acquired. In this article, we report the latest findings regarding bacteriological examinations/studies and interesting cases at these institutes, especially concerning foodborne illnesses, tuberculosis, and antimicrobial resistances.

The FDA has created a United States-based open-source whole-genome sequencing network of state, federal, international, and commercial partners. The GenomeTrakr network represents a first-of-its-kind distributed genomic food shield for characterizing and tracing foodborne outbreak pathogens back to their sources. The GenomeTrakr network is leading investigations of outbreaks of foodborne illnesses and compliance actions with more accurate and rapid recalls of contaminated foods as well as more effective monitoring of preventive controls for food manufacturing environments. An expanded network would serve to provide an international rapid surveillance system for pathogen traceback, which is critical to support an effective public health response to bacterial outbreaks.

Full Text Available Introduction: In May 2014 an outbreak of norovirus occurred among patrons of a restaurant in Melbourne, Australia. Investigations were conducted to identify the infectious agent, mode of transmission and source of illness, and to implement controls to prevent further transmission. Methods: A retrospective case-control study was conducted to test the hypothesis that food served at the restaurant between 9 and 15 May 2014 was the vehicle for infection. A structured questionnaire was used to collect demographic, illness and food exposure data from study participants. To ascertain whether any food handlers had experienced gastroenteritis symptoms and were a possible source of infection, investigators contacted and interviewed staff who had worked at the restaurant between 9 and 16 May 2014. Results: Forty-six cases (including 16 laboratory-confirmed cases of norovirus and 49 controls were interviewed and enrolled in the study. Results of the analysis revealed a statistically significant association with illness and consumption of grain salad (OR: 21.6, 95% CI: 1.8–252.7, p = 0.015 and beetroot dip (OR: 22.4, 95% CI: 1.9–267.0, p = 0.014. An interviewed staff member who reported an onset of acute gastrointestinal illness on 12 May 2014 had prepared salads on the day of onset and the previous two days. Discussion: The outbreak was likely caused by person-to-food-to-person transmission. The outbreak emphasizes the importance of the exclusion of symptomatic food handlers and strict hand hygiene practices in the food service industry to prevent contamination of ready-to-eat foods and the kitchen environment.

Foodborne diseases (FBDs) in the Caribbean have a high economic burden. Public health and tourism concerns rise along with the increasing number of cases and outbreaks registered over the last 20 years. Salmonella spp., Shigella spp., and Campylobacter spp. are the main bacteria associated with these incidents. In spite of undertaking limited surveillance on FBD in the region, records related to bacterial foodborne zoonoses in food-producing animals and their associated epidemiologic significance are poorly documented, giving rise to concerns about the importance of the livestock, food animal product sectors, and consumption patterns. In this review, we report the available published literature over the last 20 years on selected bacterial foodborne zoonoses in the Caribbean region and also address other food safety-related aspects (e.g., FBD food attribution, importance, surveillance), mainly aiming at recognizing data gaps and identifying possible research approaches in the animal health sector.

Isothiocyanates are the most intensively studied breakdown products of glucosinolates from Brassica plants and well recognized for their pleiotropic effects against cancer but also for their genotoxic potential. However, knowledge about the bioactivity of glucosinolate-borne nitriles in foods is very poor. As determined by GC-MS, broccoli glucosinolates mainly degrade to nitriles as breakdown products. The cytotoxicity of nitriles in human HepG2 cells and primary murine hepatocytes was marginal as compared to isothiocyanates. Toxicity of nitriles was not enhanced in CYP2E1-overexpressing HepG2 cells. In contrast, the genotoxic potential of nitriles was found to be comparable to isothiocyanates. DNA damage was persistent over a certain time period and CYP2E1-overexpression further increased the genotoxic potential of the nitriles. Based on actual in vitro data, no indications are given that food-borne nitriles could be relevant for cancer prevention, but could pose a certain genotoxic risk under conditions relevant for food consumption.

Listeria monocytogenes (Listeria) causes the third highest number of foodborne illness deaths (an estimated 255) in the United States annually, after nontyphoidal Salmonella species and Toxoplasma gondii (1). Deli meats are a major source of listeriosis illnesses, and meats sliced and packaged at retail delis are the major source of listeriosis illnesses attributed to deli meat (4). Mechanical slicers pose cross-contamination risks in delis and are an important source of Listeria cross-contamination. Reducing Listeria contamination of sliced meats in delis will likely reduce Listeria illnesses and outbreaks. Good slicer cleaning practices can reduce this foodborne illness risk. CDC's Environmental Health Specialists Network (EHS-Net) studied how often retail deli slicers were fully cleaned (disassembled, cleaned, and sanitized) at the Food and Drug Administration (FDA) Food Code-specified minimum frequency of every 4 hours and examined deli and staff characteristics related to slicer cleaning frequency. Interviews with staff members in 298 randomly-selected delis in six EHS-Net sites showed that approximately half of delis fully cleaned their slicers less often than FDA's specified minimum frequency. Chain-owned delis and delis with more customers, more slicers, required manager food safety training, food safety-knowledgeable workers, written slicer-cleaning policies, and food safety-certified managers fully cleaned their slicers more frequently than did other types of delis, according to deli managers or workers. States and localities should require deli manager training and certification, as specified in the FDA Food Code. They should also consider encouraging or requiring delis to have written slicer-cleaning policies. Retail food industry leaders can also implement these prevention efforts to reduce risk in their establishments. Because independent and smaller delis had lower frequencies of slicer cleaning, prevention efforts should focus on these types of

Differentiating clinical care from disease prevention: a prerequisite for practicing quaternary prevention

Directory of Open Access Journals (Sweden)

Charles Dalcanale Tesser

Full Text Available Abstract: This article contends that the distinction between clinical care (illness and prevention of future disease is essential to the practice of quaternary prevention. The authors argue that the ongoing entanglement of clinical care and prevention transforms healthy into "sick" people through changes in disease classification criteria and/or cut-off points for defining high-risk states. This diverts health care resources away from those in need of care and increases the risk of iatrogenic harm in healthy people. The distinction in focus is based on: (a management of uncertainty (more flexible when caring for ill persons; (b guarantee of benefit (required only in prevention; (c harm tolerance (nil or minimal in prevention. This implies attitudinal differences in the decision-making process: greater skepticism, scientism and resistance towards preventive action. These should be based on high-quality scientific evidence of end-outcomes that displays a net positive harm/benefit ratio.

Full Text Available Biofilms, which are complex microbial communities embedded in the protective extracellular polymeric substances (EPS, are difficult to remove in food production facilities. In this study, the use of acidic electrolyzed water (AEW to remove foodborne pathogen biofilms was evaluated. We used a green fluorescent protein-tagged Escherichia coli for monitoring the efficiency of AEW for removing biofilms, where under the optimal treatment conditions, the fluorescent signal of cells in the biofilm disappeared rapidly and the population of biofilm cells was reduced by more than 67%. Additionally, AEW triggered EPS disruption, as indicated by the deformation of the carbohydrate C-O-C bond and deformation of the aromatic rings in the amino acids tyrosine and phenylalanine. These deformations were identified by EPS chemical analysis and Raman spectroscopic analysis. Scanning electron microscopy (SEM images confirmed that the breakup and detachment of biofilm were enhanced after AEW treatment. Further, AEW also eradicated biofilms formed by both Gram-negative bacteria (Vibrio parahaemolyticus and Gram-positive bacteria (Listeria monocytogenes and was observed to inactivate the detached cells which are a potential source of secondary pollution. This study demonstrates that AEW could be a reliable foodborne pathogen biofilm disrupter and an eco-friendly alternative to sanitizers traditionally used in the food industry.

Nutrition and prevention of chronic diseases: a unifying eco-nutritional strategy.

Wahlqvist, M L

2004-02-01

Increasing efforts are being made to address, in public health policy (PHP), both the persistence of nutritional deprivation in economically disadvantaged communities, and the increase in so-called "chronic disease" (abdominal obesity, diabetes, cardiovascular disease, certain cancers, osteoporosis, arthritides, and inflammatory disease) in communities at all stages of economic development. The problems in the "chronic disease" descriptor are that its origins may be as early as conception, rather than during the postnatal lifespan, or even in previous generations; it may appear abruptly or slowly; and it may be amenable to environmental and behavioural intervention well into its course and in older age groups. It is also not necessarily "non-communicable", a qualifier often used for "chronic disease" (chronic non-communicable disease or CNCD) and often has inflammatory features, for example the inflammatory marker C-reactive protein is a predictor of macrovascular disease and ischaemic events can, in part, be prevented in the affected by influenzal vaccination. The nexus between immunodeficiency, inflammatory processes and nutritional status which is characteristic of "infective" and food-borne illness, is also more and more evident in "chronic disease". It may be more helpful to consider "chronic disease" as "eco-disease" with its environmental and behavioural contributors, and to regard that which is clearly nutritionally dependent as "eco-nutritional disease".

The production of cysts, an integral part of the life cycle of many free-living protozoa, allows these organisms to survive adverse environmental conditions. Given the prevalence of free-living protozoa in food-related environments, it is hypothesized that these organisms play an important yet currently underinvestigated role in the epidemiology of foodborne pathogenic bacteria. Intracystic bacterial survival is highly relevant, as this would allow bacteria to survive the stringent cleaning and disinfection measures applied in food-related environments. The present study shows that strains of widespread and important foodborne bacteria (Salmonella enterica, Escherichia coli, Yersinia enterocolitica, and Listeria monocytogenes) survive inside cysts of the ubiquitous amoeba Acanthamoeba castellanii, even when exposed to either antibiotic treatment (100 μg/ml gentamicin) or highly acidic conditions (pH 0.2) and resume active growth in broth media following excystment. Strain- and species-specific differences in survival periods were observed, with Salmonella enterica surviving up to 3 weeks inside amoebal cysts. Up to 53% of the cysts were infected with pathogenic bacteria, which were located in the cyst cytosol. Our study suggests that the role of free-living protozoa and especially their cysts in the persistence and epidemiology of foodborne bacterial pathogens in food-related environments may be much more important than hitherto assumed.

2012-11-01

Millions of routine restaurant inspections are performed each year in the United States, and the Centers for Disease Control and Prevention has reported that a majority of foodborne illness outbreaks occur in restaurant settings. In an attempt to relate the data collected during inspections in Minnesota to illness likelihood, data from routine inspections conducted at outbreak restaurants were compared with data from routine inspections conducted at nonoutbreak restaurants. The goal was to identify differences in recorded violations. Significantly more violations were recorded at restaurants that had outbreaks. The majority of these violations were related to contamination in the facility and environment and to food handling procedures. Relative risks also were calculated for violations significantly more likely to occur at locations that had outbreaks of norovirus infection, Clostridium perfringens infection or toxin-type illness, and Salmonella infection. These three pathogens are estimated to cause the majority of foodborne illnesses in the United States. Meta-analysis of composited data for the three pathogens revealed 11 violations significantly more likely (α restaurants than during inspections at nonoutbreak restaurants. Application of this information permits assessment of health department inspection data in a consistent fashion. This approach can help identify criteria more likely to be associated with outbreak locations and allow operators to focus on interventions that will have the most significant impact in higher risk establishments.

Full Text Available Foodborne illness burdens individuals around the world and may be caused by consuming fresh produce contaminated with bacterial, parasite, and viral pathogens. Pathogen contamination on produce may originate at the farm and packing facility. This research aimed to determine the prevalence of human pathogens (bacteria, parasites, and viruses on fresh produce (fruits, herbs, and vegetables on farms and in packing facilities worldwide through a systematic review of 38 peer-reviewed articles. The median and range of the prevalence was calculated, and Kruskal–Wallis tests and logistic regression were performed to compare prevalence among pooled samples of produce groups, pathogen types, and sampling locations. Results indicated a low median percentage of fresh produce contaminated with pathogens (0%. Both viruses (p-value = 0.017 and parasites (p-value = 0.033, on fresh produce, exhibited higher prevalence than bacteria. No significant differences between fresh produce types or between farm and packing facility were observed. These results may help to better quantify produce contamination in the production environment and inform strategies to prevent future foodborne illness.

Risky food safety behaviors are associated with higher BMI and lower healthy eating self-efficacy and intentions among African American churchgoers in Baltimore [corrected].

Elizabeth Anderson Steeves

Full Text Available BACKGROUND: There are an estimated 9.4 million cases of foodborne illness each year. Consumers have a key role in preventing foodborne illness, but differences in the practice of food safety behaviors exist, increasing risk for certain groups in the population. Identifying groups who are more likely to practice risky food safety behaviors can assist in development of interventions to reduce the disease burden of foodborne illnesses. The purpose of this investigation was to examine the relationships of health indicators and psychosocial factors with self-reported food safety behaviors. METHODS AND FINDINGS: Data were collected via questionnaire from 153 African Americans who attend churches in Baltimore City. Individuals reported high overall concern with food safety (mean score: 0.80±0.49 on a scale of -1 to +1 and practiced food safety behaviors with moderate overall frequency (mean score: 5.26±4.01 on a scale of -12 to +12, with considerable variation in reported frequencies depending on the food safety behavior. After adjusting for demographic variables, food safety behaviors were significantly associated with BMI and psychosocial variables. Riskier food safety behaviors were associated with higher body mass index (BMI (β = -0.141 95%CI (-0.237, -0.044, p = 0.004. Self-efficacy for healthy eating (standard β [std. β] = 0.250, p = 0.005 and healthy eating intentions (std. β = 0.178, p = 0.041 were associated with better food safety behaviors scores. CONCLUSIONS: These results show important relationships between weight-related health indicators, psychosocial factors and food safety behaviors that have not previously been studied. Interventions tailored to higher-risk populations have the potential to reduce the burden of food-related illnesses. Additional studies are needed to further investigate these relationships with larger and more diverse samples.

Nosocomial infections remain an important source of morbidity, mortality, and increased health care costs in hospitalized patients. This is particularly problematic in intensive care units (ICUs) because of increased patient vulnerability due to the underlying severity of illness and increased susceptibility from utilization of invasive therapeutic and monitoring devices. Lactoferrin (LF) and the products of its breakdown have multiple biological effects, which make its utilization of interest for the prevention of nosocomial infections in the critically ill. This is a phase II randomized, multicenter, double-blinded trial to determine the effect of LF on antibiotic-free days in mechanically ventilated, critically ill, adult patients in the ICU. Eligible, consenting patients will be randomized to receive either LF or placebo. The treating clinician will remain blinded to allocation during the study; blinding will be maintained by using opaque syringes and containers. The primary outcome will be antibiotic-free days, defined as the number of days alive and free of antibiotics 28 days after randomization. Secondary outcomes will include: antibiotic utilization, adjudicated diagnosis of nosocomial infection (longer than 72 h of admission to ICU), hospital and ICU length of stay, change in organ function after randomization, hospital and 90-day mortality, incidence of tracheal colonization, changes in gastrointestinal permeability, and immune function. Outcomes to inform the conduct of a larger definitive trial will also be evaluated, including feasibility as determined by recruitment rates and protocol adherence. The results from this study are expected to provide insight into a potential novel therapeutic use for LF in critically ill adult patients. Further, analysis of study outcomes will inform a future, large-scale phase III randomized controlled trial powered on clinically important outcomes related to the use of LF. The trial was registered at www

Systematic surveillance of injuries and illnesses is the foundation for developing preventive measures in sport. To analyse the injuries and illnesses that occurred during the XXII Olympic Winter Games, held in Sochi in 2014. We recorded the daily occurrence (or non-occurrence) of injuries and illnesses (1) through the reporting of all National Olympic Committee (NOC) medical teams and (2) in the polyclinic and medical venues by the Sochi 2014 medical staff. NOC and Sochi 2014 medical staff reported 391 injuries and 249 illnesses among 2780 athletes from 88 NOCs, equalling incidences of 14 injuries and 8.9 illnesses per 100 athletes over an 18-day period of time. Altogether, 12% and 8% of the athletes incurred at least one injury or illness, respectively. The percentage of athletes injured was highest in aerial skiing, snowboard slopestyle, snowboard cross, slopestyle skiing, halfpipe skiing, moguls skiing, alpine skiing, and snowboard halfpipe. Thirty-nine per cent of the injuries were expected to prevent the athlete from participating in competition or training. Women suffered 50% more illnesses than men. The rate of illness was highest in skeleton, short track, curling, cross-country skiing, figure skating, bobsleigh and aerial skiing. A total of 159 illnesses (64%) affected the respiratory system, and the most common cause of illness was infection (n=145, 58%). Overall, 12% of the athletes incurred at least one injury during the games, and 8% an illness, which is similar to prior Olympic Games. The incidence of injuries and illnesses varied substantially between sports. Published by the BMJ Publishing Group Limited.

Little is known about the cost-benefit of soft silicone foam dressings in pressure ulcer (PU) prevention among critically ill patients in the emergency department (ED) and intensive care unit (ICU). A randomised controlled trial to assess the efficacy of soft silicone foam dressings in preventing sacral and heel PUs was undertaken among 440 critically ill patients in an acute care hospital. Participants were randomly allocated either to an intervention group with prophylactic dressings applied to the sacrum and heels in the ED and changed every 3 days in the ICU or to a control group with standard PU prevention care provided during their ED and ICU stay. The results showed a significant reduction of PU incidence rates in the intervention group (P = 0·001). The intervention cost was estimated to be AU$36·61 per person based on an intention-to-treat analysis, but this was offset by lower downstream costs associated with PU treatment (AU$1103·52). Therefore, the average net cost of the intervention was lower than that of the control (AU$70·82 versus AU$144·56). We conclude that the use of soft silicone multilayered foam dressings to prevent sacral and heel PUs among critically ill patients results in cost savings in the acute care hospital. © 2013 The Authors.

In this study thymol (THY) and carvacrol (CAR), two monoterpenic phenol produced by various aromatic plants, was tested for their antibacterial and efflux pump inhibitors potencies against a panel of clinical and foodborne pathogenes. Our results demonstrated a substantial susceptibility of the tested bacteria toward THY and CAR. Especially, THY displayed a strong inhibitory activity (MIC's values ranged from 32 to 64 μg/mL) against the majority of the tested strains compared to CAR. Moreover, a significant reduction in MIC's of TET and benzalkonium chloride (QAC) were noticed when tested in combinations with THY and CAR. Their synergic effect was more significant in the case of THY which resulted a reduction of MIC's values of TET (2-8 fold) and QAC (2-8 fold). We noted also that THY and CAR inhibited the ethidium bromide (EtBr) cell efflux in a concentration-dependent manner. The rate of EtBr accumulation in food-borne pathogen was enhanced with THY and CAR (0, 250 and 500 μg/mL). The lowest concentration causing 50% of EtBr efflux inhibition (IC 50) was noticed in Salmonella enteritidis (1129) at 150 μg/mL of THY and 190 μg/mL of CAR respectively. These findings indicate that THY and CAR may serve as potential sources of efflux pump inhibitor in food-borne pathogens. Copyright © 2016 Elsevier Ltd. All rights reserved.

Rapid detection, characterization, and enumeration of foodborne pathogens.

As food safety management further develops, microbiological testing will continue to play an important role in assessing whether Food Safety Objectives are achieved. However, traditional microbiological culture-based methods are limited, particularly in their ability to provide timely data. The present review discusses the reasons for the increasing interest in rapid methods, current developments in the field, the research needs, and the future trends. The advent of biotechnology has introduced new technologies that led to the emergence of rapid diagnostic methods and altered food testing practices. Rapid methods are comprised of many different detection technologies, including specialized enzyme substrates, antibodies and DNA, ranging from simple differential plating media to the use of sophisticated instruments. The use of non-invasive sampling techniques for live animals especially came into focus with the 1990s outbreak of bovine spongiform encephalopathy that was linked to the human outbreak of Creutzfeldt Jakob's Disease. Serology is still an important tool in preventing foodborne pathogens to enter the human food supply through meat and milk from animals. One of the primary uses of rapid methods is for fast screening of large number of samples, where most of them are expected to be test-negative, leading to faster product release for sale. This has been the main strength of rapid methods such as real-time Polymerase Chain Reaction (PCR). Enrichment PCR, where a primary culture broth is tested in PCR, is the most common approach in rapid testing. Recent reports show that it is possible both to enrich a sample and enumerate by pathogen-specific real-time PCR, if the enrichment time is short. This can be especially useful in situations where food producers ask for the level of pathogen in a contaminated product. Another key issue is automation, where the key drivers are miniaturization and multiple testing, which mean that not only one instrument is flexible

Norovirus is increasingly recognized as a leading cause of outbreaks of foodborne disease. We report on an outbreak in Austria that reached a total of 176 cases, affecting pupils and teachers from four schools on a skiing holiday in a youth hostel in the province of Salzburg in December 2007. A questionnaire was sent to the four schools in order to obtain data from persons attending the school trip on disease status, clinical onset, duration of illness and hospitalization. A cohort study was undertaken to identify the sources of infection. The school trip attendees were interviewed by questionnaire or face-to-face on their exposure to food items from the menu provided by the hostel owner. Of the 284 school holiday-makers, 176 fitted the definition of an outbreak case (attack rate 61.9%). A total of 264 persons on the ski holiday participated in the cohort study (response rate 93%). The day-by-day food-specific analyses did not find any food items served on any of five days (December 8-12) of the holiday to be associated with infection risk. The day-specific risk analyses revealed Monday December 10 (RR: 9.04; 95% CI: 6.02-13.6; P Tourism is one of the primary industries in Austria. Timely involvement of the relevant public health authorities is essential in any outbreak of norovirus gastroenteritis, irrespective of its genesis.

Effects of climate change on the persistence and dispersal of foodborne bacterial pathogens in the outdoor environment: A review.

Science.gov (United States)

Hellberg, Rosalee S; Chu, Eric

2016-08-01

According to the Intergovernmental Panel on Climate Change (IPCC), warming of the climate system is unequivocal. Over the coming century, warming trends such as increased duration and frequency of heat waves and hot extremes are expected in some areas, as well as increased intensity of some storm systems. Climate-induced trends will impact the persistence and dispersal of foodborne pathogens in myriad ways, especially for environmentally ubiquitous and/or zoonotic microorganisms. Animal hosts of foodborne pathogens are also expected to be impacted by climate change through the introduction of increased physiological stress and, in some cases, altered geographic ranges and seasonality. This review article examines the effects of climatic factors, such as temperature, rainfall, drought and wind, on the environmental dispersal and persistence of bacterial foodborne pathogens, namely, Bacillus cereus, Brucella, Campylobacter, Clostridium, Escherichia coli, Listeria monocytogenes, Salmonella, Staphylococcus aureus, Vibrio and Yersinia enterocolitica. These relationships are then used to predict how future climatic changes will impact the activity of these microorganisms in the outdoor environment and associated food safety issues. The development of predictive models that quantify these complex relationships will also be discussed, as well as the potential impacts of climate change on transmission of foodborne disease from animal hosts.

Prevention of sport injuries and illnesses is a focus for epidemiological surveillance. To record and analyse all sports injuries and illnesses registered during the second Asian Beach Games. A descriptive epidemiological study using the International Olympic Committee Surveillance system to register injuries and illnesses during the second Asian Beach Games. The second Asian Beach Games hosted 1132 athletes from 43 countries competing in 14 beach sports. All National Olympic Committees' physicians of the participating teams were invited to report all injuries and illnesses. In addition, medical officers at the different Olympic venues and the main Olympic village reported injuries and illnesses treated at the clinics on a daily basis. A total of 177 injuries were reported equating to an incidence rate of 156.4 per 1000 registered athletes. Tent pegging recorded the highest incidence of injuries with 357 per 1000 registered athletes. The most prevalent injuries were in the foot/toe with 14.1% of all reported injuries. The majority of injuries were incurred during competition (75.4%). In addition, the most common mechanism of injury was contact with another athlete (n=42, 23.7%) and combined sudden and gradual overuse contributed to 30% of the total injury burden. Furthermore, 118 illnesses were reported resulting in an incidence rate of 104.2 illnesses per 1000 registered athletes. The most affected system was the respiratory tract (39.1%) with infection being the most common cause (n=33, 38.0%). The incidence of injury and illness differed significantly among the 14 sports. The data indicate that the risk of injury from beach games is sport dependant. This means that any preventive measures have to be tailored for each discipline. Furthermore, the study showed that respiratory infections are the commonest illness in beach sports and therefore, event organisers should focus improving public health measures and hygiene awareness.

Public health laboratories are an integral partner in preparedness and emergency response. The Upper Midwest Preparedness and Emergency Response Learning Center (UMPERLC) and the State Hygienic Laboratory at the University of Iowa have a long history of working together to identify and meet the preparedness training needs of the laboratory workforce. The training, Anatomy of a Foodborne Outbreak, which uses a digital story format, provides an example of this partnership. The State Hygienic Laboratory expressed the need for training programs targeted at enhancing early detection and investigation of outbreaks. Clinical laboratory staff play a significant role in identifying patient samples that may represent the effects of foodborne illness. Given that foodborne illnesses are on the increase nationally, it is critical that laboratory staff be prepared to deal with these outbreaks. UMPERLC collaborated with State Hygienic Laboratory content experts in the design and development of a digital story, using a foodborne outbreak that focuses on testing to detect Shiga toxin-producing Escherichia coli. This narrative format was selected because seeing and hearing a story about the training content provide the learner with a deeper interaction and richer learning experience, allowing the learner to better see the bigger picture. Anatomy of a Foodborne Outbreak is available on UMPERLC's Learning Management System, Training Source (http://training-source.org). Evaluation data indicate positive learning experiences overall. The digital story format, which is a video that uses a blend of images, text, and audio narration, was an appropriate method for the content and learning outcomes of the Anatomy of a Foodborne Outbreak training. This format requires more active learning, which increases retention and transfer of knowledge. Training that is easily accessed and user-friendly is an important resource for laboratory staff. When reviewing the course completion data, the highest

Globalisation is a manmade phenomenon encompassing the spread and movement of everything, animate and inanimate, material and intangible, around the planet. The intentions of globalisation may be worthy--but may also have unintended consequences. Pathogens may also be spread, enabling their establishment in new niches and exposing new human and animal populations to infection. The plethora of foodborne parasites that could be distributed by globalisation has only recently been acknowledged and will provide challenges for clinicians, veterinarians, diagnosticians, and everyone concerned with food safety. Globalisation may also provide the resources to overcome some of these challenges. It will facilitate sharing of methods and approaches, and establishment of systems and databases that enable control of parasites entering the global food chain. Copyright © 2013 Elsevier Ltd.

Swanson, Jeffrey W.; McGinty, E. Elizabeth; Fazel, Seena; Mays, Vickie M.

2015-01-01

Purpose This article describes epidemiologic evidence concerning risk of gun violence and suicide linked to psychiatric disorders, in contrast to media-fueled public perceptions of the dangerousness of mentally ill individuals, and evaluates effectiveness of policies and laws designed to prevent firearms injury and mortality associated with serious mental illnesses and substance use disorders. Methods Research concerning public attitudes toward persons with mental illness is reviewed and juxtaposed with evidence from benchmark epidemiologic and clinical studies of violence and mental illness and of the accuracy of psychiatrists' risk assessments. Selected policies and laws designed to reduce gun violence in relation to mental illness are critically evaluated; evidence-based policy recommendations are presented. Results Media accounts of mass shootings by disturbed individuals galvanize public attention and reinforce popular belief that mental illness often results in violence. Epidemiologic studies show that the large majority of people with serious mental illnesses are never violent. However, mental illness is strongly associated with increased risk of suicide, which accounts for over half of US firearms–related fatalities. Conclusions Policymaking at the interface of gun violence prevention and mental illness should be based on epidemiologic data concerning risk to improve the effectiveness, feasibility, and fairness of policy initiatives.

Case management helps prevent criminal justice recidivism for people with serious mental illness.

Science.gov (United States)

Leutwyler, Heather; Hubbard, Erin; Zahnd, Elaine

2017-09-11

Purpose The purpose of this paper is to discuss how case management can decrease recidivism for people with serious mental illness (SMI) because people with SMI are at high risk for incarceration and recidivism. Design/methodology/approach Examples of successful case management models for formerly incarcerated individuals with SMI found through a secondary analysis of qualitative data and an analysis of the literature are presented. Findings Currently, no international, national, or statewide guidelines exist to ensure that formerly incarcerated individuals with SMI receive case management upon community reentry despite evidence that such services can prevent further criminal justice involvement. Recommendations include establishment of and evaluation of best practices for case management. In addition, the authors recommend additional funding for case management with the goal of greatly increasing the number of individuals with SMI leaving the criminal justice system in their ability to access adequate case management. Originality/value Providing effective case management tailored to the needs of formerly incarcerated people with SMI improves their quality of life and reduces their involvement in the criminal justice system with clear positive outcomes for public safety and public health.

Comparative Resistance of Bacterial Foodborne Pathogens to Non-thermal Technologies for Food Preservation.

2016-01-01

In this paper the resistance of bacterial foodborne pathogens to manosonication (MS), pulsed electric fields (PEFs), high hydrostatic pressure (HHP), and UV-light (UV) is reviewed and compared. The influence of different factors on the resistance of bacterial foodborne pathogens to these technologies is also compared and discussed. Only results obtained under harmonized experimental conditions have been considered. This has allowed us to establish meaningful comparisons and draw significant conclusions. Among the six microorganisms here considered, Staphyloccocus aureus is the most resistant foodborne pathogen to MS and HHP and Listeria monocytogenes to UV. The target microorganism of PEF would change depending on the treatment medium pH. Thus, L. monocytogenes is the most PEF resistant microorganism at neutral pH but Gram-negatives (Escherichia coli, Salmonella spp., Cronobacter sakazakii, Campylobacter jejuni) would display a similar or even higher resistance at acidic pH. It should be noted that, in acidic products, the baroresistance of some E. coli strains would be comparable to that of S. aureus. The factors affecting the resistance of bacterial foodborne pathogens, as well as the magnitude of the effect, varied depending on the technology considered. Inter- and intra-specific differences in microbial resistance to PEF and HHP are much greater than to MS and UV. Similarly, both the pH and aw of the treatment medium highly condition microbial resistance to PEF and HHP but no to MS or UV. Growth phase also drastically affected bacterial HHP resistance. Regarding UV, the optical properties of the medium are, by far, the most influential factor affecting its lethal efficacy. Finally, increasing treatment temperature leads to a significant increase in lethality of the four technologies, what opens the possibility of the development of combined processes including heat. The appearance of sublethally damaged cells following PEF and HHP treatments could also be

Disturbed parent infant interactions are frequently seen in cases of parental mental illness. They are indicating possible risks of the infant's development. Regular and illness-specific patterns are not found. Therefore the interaction has to be observed and classified in each individual case to recognize the relevance of the parental illness to the child. Different interaction patterns and their impact on the child's development are described and illustrated by case vignettes. The importance of preventive intervention is highlighted.

Children of parents with a mental illness (COPMI) are at increased risk for developing psychiatric disorders, especially when parenting is compromised by multiple risk factors. Due to fragmented services, these families often do not get the support they need. Can coordination between services, as developed in the Preventive Basic Care Management (PBCM) program, improve parenting and prevent child behavioral problems? This randomized controlled clinical trial (RCT) compared the effectiveness of PBCM with a control condition. Ninety-nine outpatients of a community mental health center were randomized to intervention or control. Primary outcomes included parenting quality (assessed by the HOME instrument), parenting skills (parenting skills subscale of FFQ), and parenting stress (PDH). Secondary outcomes are child behavioral problems (SDQ). Outcomes were assessed at baseline and after 9 and 18 months. Effects were analyzed by Repeated Measures Analysis of Variance. Most families were single-parent families belonging to ethnic minorities. The results of the first RCT on effects of PBCM suggest that this intervention is feasible and has a positive effect on parenting skills. There was no evidence for effects on the quality of parenting and parenting stress, nor preventive effects on child behavioral problems. Replication studies in other sites, with more power, including monitoring of the implementation quality and studying a broader palette of child outcomes are needed to confirm the positive effects of PBCM. Long-term prospective studies are needed to investigate if improved parenting skills lead to positive effects in the children in the long run. (c) 2015 APA, all rights reserved).

Leafy greens have been associated with foodborne disease outbreaks in different countries. To decrease microbial contamination of leafy greens, chemical agents are commonly used; however, a number of studies have shown these agents to have limited antimicrobial effect against pathogenic bacteria on vegetables. The objective of this study was to compare the antibacterial effect of Hibiscus sabdariffa calyx extracts (water, methanol, acetone, and ethyl acetate), sodium hypochlorite, acetic acid, and colloidal silver against foodborne bacteria on leafy greens. Thirteen foodborne bacteria were used in the study: Listeria monocytogenes, Shigella flexneri, Salmonella serotypes Typhimurium Typhi, and Montevideo, Staphylococcus aureus, Escherichia coli O157:H7, five E. coli pathotypes (Shiga toxin-producing, enteropathogenic, enterotoxigenic, enteroinvasive, and enteroaggregative), and Vibrio cholerae O1. Each foodborne bacterium was separately inoculated on romaine lettuce, spinach, and coriander leaves. Separately, contaminated leafy greens were immersed in four hibiscus extracts and in sanitizers for 5 min. Next, green leaves were washed with sterile tap water. Separately, each green leaf was placed in a bag that contained 0.1% sterile peptone water and was rubbed for 2 min. Counts were done by plate count using appropriate dilutions (in sterile peptone water) of the bacterial suspensions spread on Trypticase soy agar plates and incubated at 35 ± 2°C for 48 h. Statistically significant differences ( P caused a significantly greater reduction ( P contaminated romaine lettuce, spinach, and coriander than did the sodium hypochlorite, colloidal silver, and acetic acid. Dry roselle calyx extracts may potentially be a useful addition to disinfection procedures for romaine lettuce, spinach, and coriander.

Fu, Ling-Lin; Li, Jian-Rong

2014-01-01

The ability to trace fecal indicators and food-borne pathogens to the point of origin has major ramifications for food industry, food regulatory agencies, and public health. Such information would enable food producers and processors to better understand sources of contamination and thereby take corrective actions to prevent transmission. Microbial source tracking (MST), which currently is largely focused on determining sources of fecal contamination in waterways, is also providing the scientific community tools for tracking both fecal bacteria and food-borne pathogens contamination in the food chain. Approaches to MST are commonly classified as library-dependent methods (LDMs) or library-independent methods (LIMs). These tools will have widespread applications, including the use for regulatory compliance, pollution remediation, and risk assessment. These tools will reduce the incidence of illness associated with food and water. Our aim in this review is to highlight the use of molecular MST methods in application to understanding the source and transmission of food-borne pathogens. Moreover, the future directions of MST research are also discussed.

The rapid high-throughput detection of foodborne pathogens is essential in controlling food safety. In this study, a 10-channel up-converting phosphor technology-based lateral flow (TC-UPT-LF) assay was established for the rapid and simultaneous detection of 10 epidemic foodborne pathogens. Ten different single-target UPT-LF strips were developed and integrated into one TC-UPT-LF disc with optimization. Without enrichment the TC-UPT-LF assay had a detection sensitivity of 104 CFU mL−1 or 105 CFU mL−1 for each pathogen, and after sample enrichment it was 10 CFU/0.6 mg. The assay also showed good linearity, allowing quantitative detection, with a linear fitting coefficient of determination (R2) of 0.916–0.998. The 10 detection channels did not cross-react, so multiple targets could be specifically detected. When 279 real food samples were tested, the assay was highly consistent (100%) with culture-based methods. The results for 110 food samples artificially contaminated with single or multiple targets showed a high detection rate (≥80%) for most target bacteria. Overall, the TC-UPT-LF assay allows the rapid, quantitative, and simultaneous detection of 10 kinds of foodborne pathogens within 20 min, and is especially suitable for the rapid detection and surveillance of foodborne pathogens in food and water.

Đurković-Đaković, O.

2017-09-01

Toxoplasma gondii is a globally distributed parasite that infects all mammals, including one third of the world population. Long known to cause disease in the developing foetus and in immunosuppressed individuals, a body of data that has emerged in the past decades suggests its role in human pathology may be even more important. The WHO and FAO have recently established toxoplasmosis as a foodborne infection of global concern, with a disease burden the greatest of all parasitic infections. Transmission of toxoplasmosis occurs by ingesting tissue cysts from undercooked meat and meat products, and oocysts from the environment with contaminated fresh produce or water. This review provides an update on the current understanding of toxoplasmosis, focusing on the risk of infection from food of animal origin, with particular reference to the risk in Serbia and the region of South-East Europe.

Wang, Yixian; Ye, Zunzhong; Ying, Yibin

2012-01-01

The development of a rapid, sensitive, specific method for the foodborne pathogenic bacteria detection is of great importance to ensure food safety and security. In recent years impedimetric biosensors which integrate biological recognition technology and impedance have gained widespread application in the field of bacteria detection. This paper presents an overview on the progress and application of impedimetric biosensors for detection of foodborne pathogenic bacteria, particularly the new trends in the past few years, including the new specific bio-recognition elements such as bacteriophage and lectin, the use of nanomaterials and microfluidics techniques. The applications of these new materials or techniques have provided unprecedented opportunities for the development of high-performance impedance bacteria biosensors. The significant developments of impedimetric biosensors for bacteria detection in the last five years have been reviewed according to the classification of with or without specific bio-recognition element. In addition, some microfluidics systems, which were used in the construction of impedimetric biosensors to improve analytical performance, are introduced in this review. PMID:22737018

Melatonin and melatonin agonists to prevent and treat delirium in critical illness: a systematic review protocol

2016-11-01

Full Text Available Abstract Background Delirium is a syndrome characterized by acute fluctuations and alterations in attention and arousal. Critically ill patients are at particularly high risk, and those that develop delirium are more likely to experience poor clinical outcomes such as prolonged duration of ICU and hospital length of stay, and increased mortality. Melatonin and melatonin agonists (MMA have the potential to decrease the incidence and severity of delirium through their hypnotic and sedative-sparing effects, thus improving health-related outcomes. The objective of this review is to synthesize the available evidence pertaining to the efficacy and safety of MMA for the prevention and treatment of ICU delirium. Methods We will search Ovid MEDLINE, Web of Science, EMBASE, PsycINFO, the Cochrane Central Register of Controlled Trials (CENTRAL, and CINAHL to identify studies evaluating MMA in critically ill populations. We will also search http://apps.who.int/trialsearch for ongoing and unpublished studies and PROSPERO for registered reviews. We will not impose restrictions on language, date, or journal of publication. Authors will independently screen for eligible studies using pre-defined criteria; data extraction from eligible studies will be performed in duplicate. The Cochrane Risk of Bias Scale and the Newcastle-Ottawa Scale will be used to assess the risk of bias and quality of randomized and non-randomized studies, respectively. Our primary outcome of interest is delirium incidence, and secondary outcomes include duration of delirium, number of delirium- and coma-free days, use of physical and chemical (e.g., antipsychotics or benzodiazepines restraints, duration of mechanical ventilation, ICU and hospital length of stay, mortality, long-term neurocognitive outcomes, hospital discharge disposition, and adverse events. We will use Review Manager (RevMan to pool effect estimates from included studies. We will present results as relative risks with

Probiotics in critically ill children [version 1; referees: 2 approved

Directory of Open Access Journals (Sweden)

Sunit C. Singhi

2016-03-01

Full Text Available Gut microflora contribute greatly to immune and nutritive functions and act as a physical barrier against pathogenic organisms across the gut mucosa. Critical illness disrupts the balance between host and gut microflora, facilitating colonization, overgrowth, and translocation of pathogens and microbial products across intestinal mucosal barrier and causing systemic inflammatory response syndrome and sepsis. Commonly used probiotics, which have been developed from organisms that form gut microbiota, singly or in combination, can restore gut microflora and offer the benefits similar to those offered by normal gut flora, namely immune enhancement, improved barrier function of the gastrointestinal tract (GIT, and prevention of bacterial translocation. Enteral supplementation of probiotic strains containing either Lactobacillus alone or in combination with Bifidobacterium reduced the incidence and severity of necrotizing enterocolitis and all-cause mortality in preterm infants. Orally administered Lactobacillus casei subspecies rhamnosus, Lactobacillus reuteri, and Lactobacillus rhamnosus were effective in the prevention of late-onset sepsis and GIT colonization by Candida in preterm very low birth weight infants. In critically ill children, probiotics are effective in the prevention and treatment of antibiotic-associated diarrhea. Oral administration of a mix of probiotics for 1 week to children on broad-spectrum antibiotics in a pediatric intensive care unit decreased GIT colonization by Candida, led to a 50% reduction in candiduria, and showed a trend toward decreased incidence of candidemia. However, routine use of probiotics cannot be supported on the basis of current scientific evidence. Safety of probiotics is also a concern; rarely, probiotics may cause bacteremia, fungemia, and sepsis in immunocompromised critically ill children. More studies are needed to answer questions on the effectiveness of a mix versus single-strain probiotics

Influenza causes significant morbidity and mortality, with considerable economic costs, including lost work productivity. Influenza vaccines may reduce the economic burden through primary prevention of influenza and reduction in illness severity. We examined illness severity and work productivity loss among working adults with medically attended acute respiratory illnesses and compared outcomes for subjects with and without laboratory-confirmed influenza and by influenza vaccination status among subjects with influenza during the 2012-2013 influenza season. Illnesses laboratory-confirmed as influenza (ie, cases) were subjectively assessed as more severe than illnesses not caused by influenza (ie, noncases) based on multiple measures, including current health status at study enrollment (≤7 days from illness onset) and current activity and sleep quality status relative to usual. Influenza cases reported missing 45% more work hours (20.5 vs 15.0; P productivity as impeded to a greater degree (6.0 vs 5.4; P productivity loss were noted for vaccinated subjects. Influenza illnesses were more severe and resulted in more missed work hours and productivity loss than illnesses not confirmed as influenza. Modest reductions in illness severity for vaccinated cases were observed. These findings highlight the burden of influenza illnesses and illustrate the importance of laboratory confirmation of influenza outcomes in evaluations of vaccine effectiveness. © The Author 2015.

Coping and resilience of children of a mentally ill parent.

Science.gov (United States)

Pölkki, Pirjo; Ervast, Sari-Anne; Huupponen, Marika

2004-01-01

This paper examines the needs and stress reactions of children of mentally ill parents, as well as coping and resilience. The study is based on the interviews of six 9-11 years old children and narratives of seventeen female grown up children of mentally ill parents. The younger and older children of the mentally ill parents had not been informed about their parent's illness. The illness of the parent aroused a variety of emotions in them. The children used both practical problem solving and emotional coping mechanisms. Informal social support was available to them but seldom from the public services. It is recommended that professionals in mental health and child welfare services clarify their roles when working with mentally ill parents. The best interest of the child and the parenting they need should be carefully assessed. Open care measures should be offered to families early enough to prevent serious child welfare and mental problems.

Food-borne disease and climate change in the United Kingdom.

Science.gov (United States)

Lake, Iain R

2017-12-05

This review examined the likely impact of climate change upon food-borne disease in the UK using Campylobacter and Salmonella as example organisms. Campylobacter is an important food-borne disease and an increasing public health threat. There is a reasonable evidence base that the environment and weather play a role in its transmission to humans. However, uncertainty as to the precise mechanisms through which weather affects disease, make it difficult to assess the likely impact of climate change. There are strong positive associations between Salmonella cases and ambient temperature, and a clear understanding of the mechanisms behind this. However, because the incidence of Salmonella disease is declining in the UK, any climate change increases are likely to be small. For both Salmonella and Campylobacter the disease incidence is greatest in older adults and young children. There are many pathways through which climate change may affect food but only a few of these have been rigorously examined. This provides a high degree of uncertainty as to what the impacts of climate change will be. Food is highly controlled at the National and EU level. This provides the UK with resilience to climate change as well as potential to adapt to its consequences but it is unknown whether these are sufficient in the context of a changing climate.

Farhana Haque

Full Text Available BACKGROUND: In 2010, an acute illness outbreak was reported in school students eating high-energy biscuits supplied by the school feeding programme in northwest Bangladesh. We investigated this outbreak to describe the illness in terms of person, place and time, develop the timeline of events, and determine the cause and community perceptions regarding the outbreak. METHODS: We defined case-patients as students from affected schools reporting any two symptoms including abdominal pain, heartburn, bitter taste, and headache after eating biscuits on the day of illness. We conducted in-depth interviews and group discussions with students, teachers, parents and community members to explore symptoms, exposures, and community perceptions. We conducted a questionnaire survey among case-patients to determine the symptoms and ascertain food items eaten 12 hours before illness onset, and microbiological and environmental investigations. RESULTS: Among 142 students seeking hospital care, 44 students from four schools qualified as case-patients. Of these, we surveyed 30 who had a mean age of 9 years; 70% (21/30 were females. Predominant symptoms included abdominal pain (93%, heartburn (90%, and bitter taste (57%. All students recovered within a few hours. No pathogenic Vibrio cholerae, Shigella or Salmonella spp. were isolated from collected stool samples. We found no rancid biscuits in schools and storage sites. The female index case perceived the unusually darker packet label as a "devil's deed" that made the biscuits poisonous. Many students, parents and community members reported concerns about rumors of students dying from biscuit poisoning. CONCLUSIONS: Rapid onset, followed by rapid recovery of symptoms; female preponderance; inconsistent physical, microbiological and environmental findings suggested mass sociogenic illness rather than a foodborne or toxic cause. Rumours of student deaths heightening community anxiety apparently propagated this

Roberts, J A; Sockett, P N; Gill, O N

1989-05-06

The recognition and investigation of an outbreak of food poisoning in 1982 due to chocolate contaminated with Salmonella napoli enabled the food that carried the salmonella to be identified and four fifths of the implicated consignment of chocolate to be withdrawn. The economic benefits of prompt intervention in the outbreak have been assessed. The cost of the outbreak was over 0.5 pounds m. It is estimated that five deaths were prevented by the intervention and that 185 admissions to hospital and 29,000 cases of S napoli enteritis were avoided. This successful investigation yielded a 3.5-fold rate of return to the public sector and a 23.3-fold return to society on an investment in public health surveillance. A methodology is described that can be used to estimate the benefits of early intervention in outbreaks of foodborne illness and topics for further research are suggested. It is concluded that public health authorities and industry have much to gain by collaborating in the research into the design of cost effective programmes to prevent foodborne infections.

Chili peppers are a very important crop in Mexico. However, these peppers have been associated with Salmonella infection outbreaks in the United States, and Salmonella and diarrheagenic Escherichia coli pathotypes have been isolated from jalapeño and serrano peppers in Mexico. To decrease microbial contamination of fruits and vegetables, chemical agents are commonly used; however, chemical agents used to eliminate pathogenic bacteria on vegetables have a limited antimicrobial effect. Roselle ( Hibiscus sabdariffa ) calyces have been reported to have an antimicrobial effect on pathogenic bacteria. In the present study, the antibacterial effect of four roselle calyx extracts (water, methanol, acetone, and ethyl acetate), sodium hypochlorite, colloidal silver, and acetic acid against foodborne bacteria was evaluated on contaminated jalapeño and serrano peppers. The 13 types of foodborne bacteria evaluated were Listeria monocytogenes , Shigella flexneri , Salmonella Typhimurium, Salmonella Typhi, Salmonella Montevideo, Staphylococcus aureus , E. coli O157:H7, five E. coli pathotypes (Shiga toxin producing, enteropathogenic, enterotoxigenic, enteroinvasive, and enteroaggregative), and Vibrio cholerae O1. All 13 types attached to both pepper types, with no significant differences in attachment between jalapeño and serrano peppers. Roselle calyx extract treatment resulted in a greater reduction in levels of all foodborne bacteria than did treatment with sodium hypochlorite, colloidal silver, and acetic acid on both pepper types. Roselle calyx extracts may be a useful for disinfection of chili peppers in the field, processing plants, restaurants, and homes.

Food Safety Challenges towards Safe, Healthy, and Nutritious Street Foods in Bangladesh

Full Text Available The street foods play an important socioeconomic role in meeting food and nutritional requirements of city consumers at affordable prices to the lower and middle income people. The number of food poisoning notifications rose steadily worldwide since the inception of E. coli O157:H7 outbreak in the 1980s to date. This may be partly attributed to improved surveillance, increased global trade and travel, changes in modern food production, the impact of modern lifestyles, changes in food consumption, and the emergence of new pathogens. Consumer’s knowledge and attitude may influence food safety behavior and practice. For the sake of public health, it is important to understand the epidemiology of foodborne illnesses that help in prevention and control efforts, appropriately allocating resources to control foodborne illness, monitoring and evaluation of food safety measures, development of new food safety standards, and assessment of the cost-effectiveness of interventions. This review paper described the sociodemographic characteristics, common hazards, and occupational hazards of street food vendors, microbial risk associated with street food, food safety interventions and control measures, regulatory aspects and legal requirements, financial constraints, and attitudes.

Gatekeepers of health: A qualitative assessment of child care centre staff's perspectives, practices and challenges to enteric illness prevention and management in child care centres

Adams Cindy L

2008-06-01

Full Text Available Abstract Background Enteric outbreaks associated with child care centres (CCC have been well documented internationally and in Canada. The current literature focuses on identifying potential risk factors for introduction and transmission of enteric disease, but does not examine why these risk factors happen, how the risk is understood and managed by the staff of CCCs, or what challenges they experience responding to enteric illness. The purpose of this study was to explore the understanding, knowledge and actions of CCC staff regarding enteric illness and outbreaks, and to identify challenges that staff encounter while managing them. Methods Focus groups were conducted with staff of regulated CCCs in Southern Ontario. Five focus groups were held with 40 participants. An open ended style of interviewing was used. Data were analyzed using content analysis. Results CCC staff play an important role in preventing and managing enteric illness. Staff used in-depth knowledge of the children, the centre and their personal experiences to assist in making decisions related to enteric illness. The decisions and actions may differ from guidance provided by public health officials, particularly when faced with challenges related to time, money, staffing and parents. Conclusion CCC staff relied on experience and judgment in coordination with public health information to assist decision-making in the management of enteric illness and outbreaks. Advice and guidance from public health officials to CCC staff needs to be consistent yet flexible so that it may be adapted in a variety of situations and meet regulatory and public health requirements.

Drying is a common process which is used to preserve food products and technological microorganisms, but which is deleterious for the cells. The aim of this study is to differentiate the effects of drying alone from the effects of the successive and necessary rehydration. Rehydration of dried bacteria is a critical step already studied in starter culture but not for different kinetics and not for pathogens. In the present study, the influence of rehydration kinetics was investigated for three foodborne pathogens involved in neonatal diseases caused by the consumption of rehydrated milk powder: Salmonella enterica subsp. enterica serovar Typhimurium, Salmonella enterica subsp. enterica serovar Senftenberg and Cronobacter sakazakii. Bacteria were dried in controlled relative humidity atmospheres and then rehydrated using different methods. Our results showed that the survival of the three pathogens was strongly related to rehydration kinetics. Consequently, rehydration is an important step to consider during food safety assessment or during studies of dried foodborne pathogens. Also, it has to be considered with more attention in consumers’ homes during the preparation of food, like powdered infant formula, to avoid pathogens recovery. PMID:27494169

2013-01-01

Staphylococcal food poisoning is one of the most frequent foodborne illnesses worldwide and it is caused by the ingestion of food contaminated with enterotoxins produced by some strains of Staphylococcus (S.) aureus. In the State of Rio Grande do Sul (RS), Southern Brazil, S. aureus has been identified as the second most frequent agent of foodborne illnesses in the last two decades. The aim of the present study was to assess and analyse the epidemiological data of S. aureus food poisoning occurred in the State of RS during the years of 2000 to 2002. The official records of epidemiological investigations carried out by the Sanitary Surveillance Services of the State of RS were analysed. Among foodborne outbreaks for which aetiology was determined, S. aureus was identified as the responsible agent of 57 foodborne outbreaks, being 42 (74%) confirmed by microbiological analyses and 15 (26%) confirmed by clinical symptoms and/or epidemiological data. Staphylococcal outbreaks were responsible for the exposition of 5,991 persons, of which 1,940 (32%) were interviewed by the Sanitary Surveillance officers. The most affected age group corresponded to people with 20 to 49 years old (48%), where men (48%) and women (52%) were affected similarly. The main involved food vehicles were meats servings (35%), followed by pastries (25%), cheese (23%), pasta (11%) and potato salad with homemade mayonnaise (11%). The majority of the outbreaks occurred inside private homes (33%) followed by commercial food establishments (28%). Inadequate control of temperature and failures in general hygiene practices were identified as the main factors responsible for the outbreaks. In conclusion, S. aureus was an important food poisoning etiological agent in the State of RS during 2000 to 2002 and its prevention depends on control measures involving different parts of the food chain.

Hazardous practices regarding antibiotics misuse, unsanitary milking procedures, and the commercial sales of raw milk and unpasteurized dairy products are currently being practiced by livestock farmers in the Sumapaz region (Colombia). The purpose of this study was to screen for food-borne and zoonotic pathogens associated with local livestock practices. We evaluated 1098 cows from 46 livestock farms in the Sumapaz region that were selected by random. Of the total population of cattle, 962 animals (88%) were tested for bovine TB using a caudal-fold tuberculin test and 546 (50%) for brucellosis by a competitive ELISA. In the population tested, 23 cows were positive for Brucella sp. representing a 4.2% seroprevalence and no cases of bovine tuberculosis were found. In addition, food-borne contamination with Escherichia coli and Staphylococcus aureus was assessed together with antibiotic susceptibility for ten different antibiotics in milk samples from 16 livestock farms. We found that 12 of the farms (75%) were contaminated with these food-borne pathogens. Noteworthy, all of the isolated pathogenic strains were resistant to multiple antibiotics, primarily to oxytetracycline and erythromycin. Our findings suggest that livestock products could be a source of exposure to Brucella and multidrug-resistant E. coli and S. aureus strains as a result of unhygienic livestock practices in the Sumapaz region. Training in good farming practices is the key to improving safety in food production.

To analyse the frequency and characteristics of sports injuries and illnesses incurred during the World Athletics Championships. Prospective recording of newly occurred injuries and illnesses. Twelfth International Association of Athletics Federations World Championships in Athletics 2009 in Berlin, Germany. National team physicians and physiotherapists and 1979 accredited athletes; Local Organising Committee physicians working in the Medical Centres. Incidence and characteristics of newly incurred injuries and illnesses. 236 injury incidents with 262 injured body parts and 269 different injury types were reported, representing an incidence of 135.4 injuries per 1000 registered athletes. Eighty percent affected the lower extremity. Thigh strain (13.8%) was the main diagnosis. Overuse (44.1%) was the predominant cause. Most injuries were incurred during competition (85.9%). About 43.8% of all injury events were expected to result in time-loss. 135 illnesses were reported, signifying an incidence of 68.2 per 1000 registered athletes. Upper respiratory tract infection was the most common condition (30.4%) and infection was the most frequent cause (32.6%). The incidence of injury and illnesses varied substantially among the events. The risk of injury varied with each discipline. Preventive measures should be specific and focused on minimising the potential for overuse. Attention should be paid to ensure adequate rehabilitation of previous injuries. The addition of the illness part to the injury surveillance system proved to be feasible. As most illnesses were caused by infection of the respiratory tract or were environmentally related, preventive interventions should focus on decreasing the risk of transmission, appropriate event scheduling and heat acclimatisation.

Mental illness, mass shootings, and the politics of American firearms.

Metzl, Jonathan M; MacLeish, Kenneth T

2015-02-01

Four assumptions frequently arise in the aftermath of mass shootings in the United States: (1) that mental illness causes gun violence, (2) that psychiatric diagnosis can predict gun crime, (3) that shootings represent the deranged acts of mentally ill loners, and (4) that gun control "won't prevent" another Newtown (Connecticut school mass shooting). Each of these statements is certainly true in particular instances. Yet, as we show, notions of mental illness that emerge in relation to mass shootings frequently reflect larger cultural stereotypes and anxieties about matters such as race/ethnicity, social class, and politics. These issues become obscured when mass shootings come to stand in for all gun crime, and when "mentally ill" ceases to be a medical designation and becomes a sign of violent threat.

As in other countries worldwide, adults with severe mental illness (SMI) in Brazil are disproportionately infected with HIV relative to the general population. Brazilian psychiatric facilities lack tested HIV prevention interventions. To adapt existing interventions, developed only in the US, we conducted targeted ethnography with adults with SMI and staff from two psychiatric institutions in Brazil. We sought to characterize individual, institutional, and interpersonal factors that may affect HIV risk behavior in this population. We conducted 350 hours of ethnographic field observations in two mental health service settings in Rio de Janeiro, and 9 focus groups (n=72) and 16 key-informant interviews with patients and staff in these settings. Data comprised field notes and audiotapes of all exchanges, which were transcribed, coded, and systematically analyzed. The ethnography identified and/or characterized the institutional culture: (1) patients' risk behaviors; (2) the institutional setting; (3) intervention content; and (4) intervention format and delivery strategies. Targeted ethnography also illuminated broader contextual issues for development and implementation of HIV prevention interventions for adults with SMI in Brazil, including an institutional culture that did not systematically address patients' sexual behavior, sexual health, or HIV sexual risk, yet strongly impacted the structure of patients' sexual networks. Further, ethnography identified the Brazilian concept of "social responsibility" as important to prevention work with psychiatric patients. Targeted ethnography with adults with SMI and institutional staff provided information critical to the adaptation of tested US HIV prevention interventions for Brazilians with SMI.

Soonthorndhada, K

1989-07-01

This paper examines 3 major health-related issues: 1) existing health problems and illnesses resulting from physical environmental conditions at workplaces; 2) female workers' perception on illness and health protection; and 3) the relationship between illness and risk factors. The study area is textile factories in Bangkok and its peripheries. Data are drawn from the 1987 Survey of Occupational Health and Textile Industrial Development in Thailand: Effect on Health and Socioeconomics of Female Migrant Workers. This study shows that about 20% of female workers have ill-health problems and illness after a period of working mainly due to high levels of dust and noise, and inadequate light. These conditions are hazardous to the respiratory system (resulting in cough and chest tightness), the hearing system (pains as well as impaired and hearing loss), eye systems (irritation, reduced visual capacity) and skin allergy. Such illnesses are intensified in the long- run. The analysis of variances reveals that education, section of work, perception (particularly mask and ear plug) significantly affect these illnesses. This study concludes that health education and occupational health should be provided in factories with emphasis on health prevention and promotion.

Pulmonary embolism (PE) is a potentially life-threatening complication of critical illness. In trauma and neurosurgical patients with contraindications to anticoagulation, inferior vena cava (IVC) filters have been used to prevent PE, but their associated long-term complication rates and difficulties associated with filter removal have limited their use. The Angel catheter is a temporary device, which combined an IVC filter with a triple-lumen central venous catheter (IVC filter-catheter) and is intended for bedside placement and removal when no longer indicated. This study presents data from a European Registry of 60 critically ill patients in whom the IVC filter-catheter was used to prevent PE. The patients were all at high risk of PE development or recurrence and had contraindications to anticoagulation. The primary end points of this study were to evaluate the safety (in particular, the presence of infectious or thrombotic events) and effectiveness (the numbers of PEs and averted PEs) of the IVC filter-catheter. The main diagnosis before catheter insertion was major trauma in 33 patients (55%), intracerebral hemorrhage or stroke in 9 (15%), a venous thromboembolic event in 9 (15%), and active bleeding in 6 (10%). The IVC filter-catheter was placed as prophylaxis in 51 patients (85%) and as treatment in the 9 patients (15%) with venous thromboembolic event. The devices were inserted at the bedside without fluoroscopic guidance in 54 patients (90%) and within a median of 4 days after hospital admission. They were left in place for a mean of 6 days (4-8 days). One patient developed a PE, without hemodynamic compromise; two PEs were averted. No serious adverse events were reported. Early bedside placement of an IVC filter-catheter is possible, and our results suggest that this is a safe, effective alternative to short-term PE prophylaxis for high-risk patients with contraindications to anticoagulation.

Helicobacter pylori is an organism widespread in humans and sometimes responsible for serious illnesses, such as gastric and duodenal ulcers, MALToma and even gastric cancer. It has been hypothesized that the infection route by H. pylori involves multiple pathways including food-borne transmission, as the microorganism has been detected from foods such as sheep and cow milk. This work reports the results of a survey conducted in order to investigate the presence of H. pylori in raw goat, sheep and cow milk produced in Southern Italy, employing a Nested Polymerase Chain Reaction (Nested-PCR) assay for the detection of the phosphoglucosamine mutase gene (glmM), as screening method followed by conventional bacteriological isolation. Out of the 400 raw milk samples examined, 139 (34.7%) resulted positive for the presence of glmM gene, but no strains were isolated. In this work H. pylori DNA has been firstly detected from 41 (25.6%) raw goat milk samples. The results deserve further investigations on the contamination source/s of the milk samples and on the major impact that it may have on consumers.

If our findings are replicated, they would suggest that programmes empowering people in treatment for mental illness to cope with anticipated and experienced discrimination as well as interventions to reduce public stigma within society could improve suicide prevention.

Pathogens with animal reservoirs (e.g. non-typhoidal Salmonella spp. and Toxoplasma gondii) were in general assessed by the experts to have a higher proportion of illnesses attributable to food than pathogens with mainly a human reservoir, where human-to-human transmission (e.g. Shigella spp. and Norovirus) or waterborne transmission (e.g. Salmonella Typhi and Vibrio cholerae) were judged to dominate. For many pathogens, the foodborne route was assessed relatively more important in developed subregions than in developing subregions. The main exposure routes for lead varied across subregions, with the foodborne route being assessed most important only in two subregions of the European region. For the first time, we present worldwide estimates of the proportion of specific diseases attributable to food and other major transmission routes. These findings are essential for global burden of FBD estimates. While gaps exist, we believe the estimates presented here are the best current source of guidance to support decision makers when allocating resources for control and intervention, and for future research initiatives.

Kirbiš, A.; Raspor Lainšček, P.

2017-09-01

Hepatitis E (HE) is a zoonosis caused by hepatitis E virus (HEV). The disease that used to be problematic only in developing regions with inadequate water supplies and poor sanitary conditions is now considered one of the foodborne diseases in industrialized countries as well. According to current knowledge, the main reservoir of the virus is linked to domestic swine and wild boar. Consumption of raw or undercooked pork meat and liver is considered as a risk factor for HE human infection, together with some other sources of infection like blood transfusion or organ transplantation. Although the number of cases has been rising in the last decade, HEV is still a generally unknown virus among the general public. Consumers need to be warned and educated about HEV and its potential sources of contamination within the food supply chain.

The present study examines the concept of illness identity, the degree to which a chronic illness is integrated into one's identity, in adults with a chronic illness by validating a new self-report questionnaire, the Illness Identity Questionnaire (IIQ). Self-report questionnaires on illness identity, psychological, and physical functioning were assessed in two samples: adults with congenital heart disease (22-78 year old; n = 276) and with multisystem connective tissue disorders (systemic lupus erythematosus or systemic sclerosis; 17-81 year old; n = 241). The IIQ could differentiate four illness identity states (i.e., engulfment, rejection, acceptance, and enrichment) in both samples, based on exploratory and confirmatory factor analysis. All four subscales proved to be reliable. Rejection and engulfment were related to maladaptive psychological and physical functioning, whereas acceptance and enrichment were related to adaptive psychological and physical functioning. The present findings underscore the importance of the concept of illness identity. The IIQ, a self-report questionnaire, is introduced to measure four different illness identity states in adults with a chronic illness.

Approaches to self-management in chronic illness.

Management of a chronic medical condition is a complex process and requires coordinated action between healthcare providers and patients. This process is further complicated by the fact that an increasing number of patients suffer from multiple chronic conditions. Self-management involves active participation of the patients in the everyday care of the symptoms of their illness(es) and medical treatments, as well as maintaining general health and prevention of progression of medical conditions. Managing the psychosocial consequences of illness is also an important component of self-management. Data have demonstrated that enhancing self-management improves quality of life, coping, symptom management, disability, and reduces healthcare expenditures and service utilization. To foster self-management, potential barriers to implementation as well as facilitators and supports for this approach must be acknowledged. In this article, we review various aspects of self-management in chronic illness, focusing on chronic kidney disease. Better understanding of these concepts will facilitate patient-provider collaboration, improve patient care with increased patient and staff satisfaction, and may ultimately result in better clinical outcomes and enhanced quality of life for both the patients and their families. © 2013 Wiley Periodicals, Inc.

Food, health, and complexity: towards a conceptual understanding to guide collaborative public health action

Full Text Available Abstract Background What we eat simultaneously impacts our exposure to pathogens, allergens, and contaminants, our nutritional status and body composition, our risks for and the progression of chronic diseases, and other outcomes. Furthermore, what we eat is influenced by a complex web of drivers, including culture, politics, economics, and our built and natural environments. To date, public health initiatives aimed at improving food-related population health outcomes have primarily been developed within ‘practice silos’, and the potential for complex interactions among such initiatives is not well understood. Therefore, our objective was to develop a conceptual model depicting how infectious foodborne illness, food insecurity, dietary contaminants, obesity, and food allergy can be linked via shared drivers, to illustrate potential complex interactions and support future collaboration across public health practice silos. Methods We developed the conceptual model by first conducting a systematic literature search to identify review articles containing schematics that depicted relationships between drivers and the issues of interest. Next, we synthesized drivers into a common model using a modified thematic synthesis approach that combined an inductive thematic analysis and mapping to synthesize findings. Results The literature search yielded 83 relevant references containing 101 schematics. The conceptual model contained 49 shared drivers and 227 interconnections. Each of the five issues was connected to all others. Obesity and food insecurity shared the most drivers (n = 28. Obesity shared several drivers with food allergy (n = 11, infectious foodborne illness (n = 7, and dietary contamination (n = 6. Food insecurity shared several drivers with infectious foodborne illness (n = 9 and dietary contamination (n = 9. Infectious foodborne illness shared drivers with dietary contamination (n = 8. Fewer drivers were

Injury and illness surveillance during high-level youth sports events is an important first step in health prevention and caretaking of the young elite athletes. To analyse injuries and illnesses that occurred during the 10 days 2nd Youth Olympic Winter Games (YOG), held in Lillehammer 2016. We recorded the daily occurrence (or non-occurrence) of injuries and illnesses through the reporting of (1) all National Olympic Committee (NOC) medical teams and (2) the polyclinic and medical venues by the Lillehammer Organising Committee (LYOCOG) medical staff. In total, 1083 athletes (48 double-starters), 46% (n=502) of them females, from 70 NOCs were registered in the study. NOCs and LYOCOG reported 108 injuries and 81 illnesses, equalling to 9.5 injuries and 7.2 illnesses per 100 athletes. The percentage of injured athletes was highest in the snowboard and ski slopestyle and cross disciplines, alpine skiing and skeleton, and lowest in the Nordic skiing disciplines. Approximately, two-thirds of the injuries (n=71, 65.7%) prevented the athlete from training or competition, while 10 injuries (9.3%) were registered with an estimated absence from sport for >7 days. The rate of illness was highest in curling and the Nordic skiing disciplines with most of them being respiratory tract infections (81.5%). Overall, 9% of the athletes incurred at least one injury during the games, and 7% an illness, which is similar to the first YOG in Innsbruck 2012 and slightly lower compared with previous Winter Olympic Games. The incidence of injuries and illnesses varied substantially between sports. Published by the BMJ Publishing Group Limited.

To test whether hydration with bicarbonate rather than isotonic sodium chloride reduces the risk of contrast-associated acute kidney injury in critically ill patients. Prospective, double-blind, multicenter, randomized controlled study. Three French ICUs. Critically ill patients with stable renal function (n = 307) who received intravascular contrast media. Hydration with 0.9% sodium chloride or 1.4% sodium bicarbonate administered with the same infusion protocol: 3 mL/kg during 1 hour before and 1 mL/kg/hr during 6 hours after contrast medium exposure. The primary endpoint was the development of contrast-associated acute kidney injury, as defined by the Acute Kidney Injury Network criteria, 72 hours after contrast exposure. Patients randomized to the bicarbonate group (n = 151) showed a higher urinary pH at the end of the infusion than patients randomized to the saline group (n = 156) (6.7 ± 2.1 vs 6.2 ± 1.8, respectively; p 0.99) were also similar between the saline and bicarbonate groups, respectively. Except for urinary pH, none of the outcomes differed between the two groups. Among ICU patients with stable renal function, the benefit of using sodium bicarbonate rather than isotonic sodium chloride for preventing contrast-associated acute kidney injury is marginal, if any.

Preventive interventions are developed for children of parents with mental and substance use disorders (COPMI), because these children have a higher risk of developing a psychological or behavioral disorder in the future. Mental health and substance use disorders contribute significantly to the global burden of disease. Although the exact number of parents with a mental illness is unclear, the subject of mentally ill parents is gaining attention. Moreover there is a lack of interventions for COPMI-children, as well of (cost-) effectiveness studies evaluating COPMI interventions. Innovative interventions such as e-health provide a new field for exploration. There is no knowledge about the opportunities for using the internet to prevent problems in children at risk. In the current study we will focus on the (cost-) effectiveness of an online health prevention program for COPMI-children. We designed a randomized controlled trial to examine the (cost-) effectiveness of the Kopstoring intervention. Kopstoring is an online intervention for COPMI-children to strengthen their coping skills and prevent behavioral and psychological problems. We will compare the Kopstoring intervention with (waiting list) care as usual. This trial will be conducted entirely over the internet. An economic evaluation, from a societal perspective will be conducted, to examine the trial's cost-effectiveness. Power calculations show that 214 participants are needed, aged 16-25. Possible participants will be recruited via media announcements and banners on the internet. After screening and completing informed consent procedures, participants will be randomized. The main outcome is internalizing and externalizing symptoms as measured by the Youth Self Report. For the economic evaluation, healthcare costs and costs outside the healthcare sector will be measured at the same time as the clinical measures, at baseline, 3, 6 and 9 months. An extended measure for the intervention group will be provided at

Full Text Available INTRODUCTION: At a time when a great number of diseases can be prevented by changing one's habits and life style, investigations have focused on understanding what adults and children believe to be desirable health practices and uncovering the factors associated with successful adherence to such practices. For these, causal attributions for health and illness were investigated among 96 Brazilian elementary school students. METHODS: Ninety six subjects, aged 6 to 14, were interviewed individually and their causal attributions were assessed through 14 true-false items (e.g. people stay well [healthy] because they are lucky. The relationship between the children's causal attributions and demographic characteristics were also examined. RESULTS: Overall, the results were consistent with previous researches. "Taking care of oneself" was considered the most important cause of good health. "Viruses and germs" and "lack of self-care" were the most selected causes of illness. Analyses revealed significant relationship between subjects' causal attribution and their age, school grade level, socioeconomic status and gender. CONCLUSIONS: The study findings suggest that there may be more cross-cultural similarities than differences in children's causal attributions for health and illness. Finding ways to help individuals engage in appropriate preventive-maintenance health practices without developing an exaggerated notion that the individuals can control their own health and illness is a challenge which remains to be addressed by further research.

Changing the tide: stigma, school youth, and mental illness.

Schools are in a key position not only to identify mental health concerns early but to address issues of stigma that prevent both children and their parents from seeking help with mental illness. Stigma associated with mental illness perpetuates isolative behavior and poor engagement within the academic community. Programs within schools that address mental health issues and support open communication with families can reduce the pain and isolation that is often the experience of youth with undiagnosed and untreated mental and emotional disorders. © 2014 The Author(s).

Nutrition, illness, and injury in aquatic sports.

Pyne, David B; Verhagen, Evert A; Mountjoy, Margo

2014-08-01

In this review, we outline key principles for prevention of injury and illness in aquatic sports, detail the epidemiology of injury and illness in aquatic athletes at major international competitions and in training, and examine the relevant scientific evidence on nutrients for reducing the risk of illness and injury. Aquatic athletes are encouraged to consume a well-planned diet with sufficient calories, macronutrients (particularly carbohydrate and protein), and micronutrients (particularly iron, zinc, and vitamins A, D, E, B6, and B12) to maintain health and performance. Ingesting carbohydrate via sports drinks, gels, or sports foods during prolonged training sessions is beneficial in maintaining energy availability. Studies of foods or supplements containing plant polyphenols and selected strains of probiotic species are promising, but further research is required. In terms of injury, intake of vitamin D, protein, and total caloric intake, in combination with treatment and resistance training, promotes recovery back to full health and training.

In February 2016, an outbreak of gastroenteritis occurred in a French military unit located in Poitiers, France. Attack rate was of 34% (103/300). A case-control study identified association between illness and cake consumption. Stool samples were tested positive for Norovirus GII.17 for one patient and one post-symptomatic food worker (FW). The FW presented vomiting one day before cake preparation. The NoV strain was probably spread through food worker hand contact. Prevention of Norovirus foodborne outbreaks implies new guidelines for FWs management in France and Europe.

We test whether significant differences in mental illness exist in a matched sample of lone- and group-based terrorists. We then test whether there are distinct behavioral differences between lone-actor terrorists with and without mental illness. We then stratify our sample across a range of diagnoses and again test whether significant differences exist. We conduct a series of bivariate, multivariate, and multinomial statistical tests using a unique dataset of 119 lone-actor terrorists and a matched sample of group-based terrorists. The odds of a lone-actor terrorist having a mental illness is 13.49 times higher than the odds of a group actor having a mental illness. Lone actors who were mentally ill were 18.07 times more likely to have a spouse or partner who was involved in a wider movement than those without a history of mental illness. Those with a mental illness were more likely to have a proximate upcoming life change, more likely to have been a recent victim of prejudice, and experienced proximate and chronic stress. The results identify behaviors and traits that security agencies can utilize to monitor and prevent lone-actor terrorism events. The correlated behaviors provide an image of how risk can crystalize within the individual offender and that our understanding of lone-actor terrorism should be multivariate in nature.

2017-01-01

In the present work, we applied a shotgun proteomics approach for the fast and easy characterization of 20 different foodborne strains of Staphylococcus aureus (S. aureus), one of the most recognized foodborne pathogenic bacteria. A total of 644 non-redundant proteins were identified and analyzed via an easy and rapid protein sample preparation procedure. The results allowed the differentiation of several proteome datasets from the different strains (common, accessory, and unique datasets), which were used to determine relevant functional pathways and differentiate the strains into different Euclidean hierarchical clusters. Moreover, a predicted protein-protein interaction network of the foodborne S. aureus strains was created. The whole confidence network contains 77 nodes and 769 interactions. Most of the identified proteins were surface-associated proteins that were related to pathways and networks of energy, lipid metabolism and virulence. Twenty-seven virulence factors were identified, and most of them corresponded to autolysins, N-acetylmuramoyl-L-alanine amidases, phenol-soluble modulins, extracellular fibrinogen-binding proteins and virulence factor EsxA. Potential species-specific peptide biomarkers were screened. Twenty-one species-specific peptide biomarkers, belonging to eight different proteins (nickel-ABC transporter, N-acetylmuramoyl-L-alanine amidase, autolysin, clumping factor A, gram-positive signal peptide YSIRK, cysteine protease/staphopain, transcriptional regulator MarR, and transcriptional regulator Sar-A), were proposed to identify S. aureus. These results constitute the first major dataset of peptides and proteins of foodborne S. aureus strains. This repository may be useful for further studies, for the development of new therapeutic treatments for S. aureus food intoxications and for microbial source-tracking in foodstuffs. PMID:29312172

Listeriosis and toxoplasmosis are foodborne illnesses that can have long-term consequences when contracted during pregnancy. Listeriosis is implicated in stillbirth, preterm labor, newborn sepsis, and meningitis, among other complications. Toxoplasmosis is associated with blindness, cognitive delays, seizures, and hearing loss, among other significant disabilities. Healthcare providers who understand the fundamentals of Listeria and Toxoplasma infection will have the tools to identify symptoms and high-risk behaviors, educate women to make safer decisions, and provide anticipatory guidance if a pregnant woman would become infected with either of these foodborne illnesses.

Controversy continues concerning antimicrobial use in food animals and its relationship to drug-resistant infections in humans. We systematically reviewed published literature for evidence of a relationship between antimicrobial use in agricultural animals and drug-resistant foodborne campylobacteriosis in humans. Based on publications from the United States (U.S.), Canada and Denmark from 2010 to July 2014, 195 articles were retained for abstract review, 50 met study criteria for full article review with 36 retained for which data are presented. Two publications reported increase in macrolide resistance of Campylobacter coli isolated from feces of swine receiving macrolides in feed, and one of these described similar findings for tetracyclines and fluoroquinolones. A study in growing turkeys demonstrated increased macrolide resistance associated with therapeutic dosing with Tylan® in drinking water. One publication linked tetracycline-resistant C. jejuni clone SA in raw cow's milk to a foodborne outbreak in humans. No studies that identified farm antimicrobial use also traced antimicrobial-resistant Campylobacter from farm to fork. Recent literature confirms that on farm antibiotic selection pressure can increase colonization of animals with drug-resistant Campylobacter spp. but is inadequately detailed to establish a causal relationship between use of antimicrobials in agricultural animals and prevalence of drug-resistant foodborne campylobacteriosis in humans.

Full Text Available Foodborne diseases are a recognized problem worldwide and the search is on to discover novel antimicrobial agents from natural sources that can replace the use of synthetic antimicrobial compounds. One of such sources are microalgae. The antibacterial efficacy of pigment extract from Scenedesmus sp. was tested against foodborne Staphylococcusaureus. The extract was prepared using 90% acetone and varying amounts was added to food suspension spiked with a known volume of the bacteria. Antibacterial activity was observed and evaluated through bacterial colony counts. Uncountable bacterial colonies were observed in the sample with 0.41 mg/ml and 0.81 mg/ml concentration of pigment extract as they were TMTC and there was no growth of bacterial colonies in samples with 2.83 mg/ml - 4.05 mg/ml concentration of pigment extract.The results of this study suggest that Scenedesmus sp. is a potential source of antibacterial compounds for food applications as an additive.

Background Globally, Médecins Sans Frontières (MSF) treats more than 300,000 severely malnourished children annually. Malnutrition is not only caused by lack of food but also by illnesses and by poor infant and child feeding practices. Breaking the vicious cycle of illness and malnutrition by providing ill children with nutritional supplementation is a potentially powerful strategy for preventing malnutrition that has not been adequately investigated. Therefore, MSF investigated whether incidence of malnutrition among ill children malnutrition rate between 8.4% and 11.5% of which 2% to 3% severe malnutrition, more than half (58%) of the population in the district of Kaabong is considered food insecure. Methods and Findings We investigated the effect of two types of nutritional supplementation on the incidence of malnutrition in ill children presenting at outpatient clinics during March 2011 to April 2012 in Kaabong, Karamoja region, Uganda, a resource-poor region where malnutrition is a chronic problem for its seminomadic population. A three-armed, partially-blinded, randomised controlled trial was conducted in children diagnosed with malaria, diarrhoea, or lower respiratory tract infection. Non-malnourished children aged 6 to 59 mo were randomised to one of three arms: one sachet/d of ready-to-use therapeutic food (RUTF), two sachets/d of micronutrient powder (MNP), or no supplement (control) for 14 d for each illness over 6 mo. The primary outcome was the incidence of first negative nutritional outcome (NNO) during the 6 mo follow-up. NNO was a study-specific measure used to indicate progression to moderate or severe acute malnutrition; it was defined as weight-for-height z-score malnutrition in eastern Uganda. The low incidence of malnutrition in this population may warrant a more targeted intervention to improve cost effectiveness. Trial Registration clinicaltrials.gov NCT01497236 PMID:26859481

Arcobacter has emerged as an important food-borne zoonotic pathogen, causing sometimes serious infections in humans and animals. Newer species of Arcobacter are being incessantly emerging (presently 25 species have been identified) with novel information on the evolutionary mechanisms and genetic diversity among different Arcobacter species. These have been reported from chickens, domestic animals (cattle, pigs, sheep, horses, dogs), reptiles (lizards, snakes and chelonians), meat (poultry, pork, goat, lamb, beef, rabbit), vegetables and from humans in different countries. Arcobacters are implicated as causative agents of diarrhea, mastitis and abortion in animals, while causing bacteremia, endocarditis, peritonitis, gastroenteritis and diarrhea in humans. Three species including A. butzleri, A. cryaerophilus and A. skirrowii are predominantly associated with clinical conditions. Arcobacters are primarily transmitted through contaminated food and water sources. Identification of Arcobacter by biochemical tests is difficult and isolation remains the gold standard method. Current diagnostic advances have provided various molecular methods for efficient detection and differentiation of the Arcobacters at genus and species level. To overcome the emerging antibiotic resistance problem there is an essential need to explore the potential of novel and alternative therapies. Strengthening of the diagnostic aspects is also suggested as in most cases Arcobacters goes unnoticed and hence the exact epidemiological status remains uncertain. This review updates the current knowledge and many aspects of this important food-borne pathogen, namely etiology, evolution and emergence, genetic diversity, epidemiology, the disease in animals and humans, public health concerns, and advances in its diagnosis, prevention and control.

Latalova, Klara; Kamaradova, Dana; Prasko, Jan

2014-01-01

The aims of this paper are to review data on the prevalence and correlates of violent victimization of persons with severe mental illness, to critically evaluate the literature, and to explore possible approaches for future research. PubMed/MEDLINE and PsycINFO databases were searched using several terms related to severe mental illness in successive combinations with terms describing victimization. The searches identified 34 studies. Nine epidemiological studies indicate that patients with severe mental illness are more likely to be violently victimized than other community members. Young age, comorbid substance use, and homelessness are risk factors for victimization. Victimized patients are more likely to engage in violent behavior than other members of the community. Violent victimization of persons with severe mental illness has long-term adverse consequences for the course of their illness, and further impairs the quality of lives of patients and their families. Victimization of persons with severe mental illness is a serious medical and social problem. Prevention and management of victimization should become a part of routine clinical care for patients with severe mental illness.

Hand washing is the most effective way to prevent the spread of communicable disease. The purpose of this double-blind, placebo-controlled study was to assess whether an alcohol-free, instant hand sanitizer containing surfactants, allantoin, and benzalkonium chloride could reduce illness absenteeism in a population of 769 elementary school children and serve as an effective alternative when regular soap and water hand washing was not readily available. Prior to the study, students were educated about proper hand washing technique, the importance of hand washing to prevent transmission of germs, and the relationship between germs and illnesses. Children in kindergarten through the 6th grade (ages 5-12) were assigned to the active or placebo hand-sanitizer product and instructed to use the product at scheduled times during the day and as needed after coughing or sneezing. Data on illness absenteeism were tracked. After 5 weeks, students using the active product were 33% less likely to have been absent because of illness when compared with the placebo group.

Many women with postnatal mental illness do not get the treatment they need and this is often because stigma prevents disclosure. The purpose of this study was to explore online social support for postnatal mental illness, how women experience stigma and potential disadvantages of using Internet forums. Interviews were conducted with fifteen participants who had suffered postnatal mental illness and had used forums. Systematic thematic analysis identified common themes in relation to social support, stigma and disadvantages of using forums. Most women felt they benefited from visiting forums by developing a shared understanding and discourse about their illness. Findings suggest future research should investigate if women benefit from using online social support provided by forums, if use challenges stigma and further explore potential concerns about using forums.

We have developed a microfluidic chip for use in an RNA-DNA hybridization assay for foodborne pathogens. Automatic sequential reagent dispensing and washing was realized with a programmable DC voltage sequencer. Signal detection was achieved with a miniaturized optical detection module. Salmonella and Listeria monocytogenes bacteria in different concentrations were quantitatively determined by this RNA-DNA hybridization assay in the microfluidic chip. The detection limit for the Salmonella and Listeria monocytogenes bacteria is 10 3 to 10 4 CFU mL -1 . The method excels by a significant reduction in the consumption of sample and reagent, and a short assay time. This automatic-operating microfluidic RNA-DNA hybridization assay is promising for on-site pathogen detection. (author)

Toll-like receptor 4 (TLR4) initiates immune response against Gram-negative bacteria upon specific recognition of lipid A moiety of lipopolysaccharide (LPS), the major component of their cell wall. Some natural differences between LPS variants in their ability to interact with TLR4 may lead to either insufficient activation that may not prevent bacterial growth, or excessive activation which may lead to septic shock. In this study we evaluated the biological activity of LPS isolated from pathogenic strain of Campylobacter jejuni , the most widespread bacterial cause of foodborne diarrhea in humans. With the help of hydrophobic chromatography and MALDI-TOF mass spectrometry we showed that LPS from a C. jejuni strain O2A consists of both hexaacyl and tetraacyl forms. Since such hypoacylation can result in a reduced immune response in humans, we assessed the activity of LPS from C. jejuni in mouse macrophages by measuring its capacity to activate TLR4-mediated proinflammatory cytokine and chemokine production, as well as NFκB-dependent reporter gene transcription. Our data support the hypothesis that LPS acylation correlates with its bioactivity.

Full Text Available The child’s illness, suffering and death provoke many emotions in the family. The ill child and its family both experience grief which is an emotional reaction to the danger of losing health or life. Support offered by home hospices for children aims at overcoming the destructive influence of illness. A hospice counsellor’s task is to improve the ill child and its family’s quality of life. He is helping the family overcome grief and prepare for the child’s death. The hospice team supports the family members who experience anticipatory and later, actual mourning. Preventing pathological effects of grief is a basic challenge for people who offer help.

Staphylococcus aureus is an important aetiological agent of food intoxications in the European Union as it can cause gastro-enteritis through the production of various staphylococcal enterotoxins (SEs) in foods. Reported enterotoxin dose levels causing food-borne illness are scarce and varying. Three food poisoning outbreaks due to enterotoxin-producing S. aureus strains which occurred in 2013 in Belgium are described. The outbreaks occurred in an elderly home, at a barbecue event and in a kindergarten and involved 28, 18, and six cases, respectively. Various food leftovers contained coagulase positive staphylococci (CPS). Low levels of staphylococcal enterotoxins ranging between 0.015 ng/g and 0.019 ng/g for enterotoxin A (SEA), and corresponding to 0.132 ng/g for SEC were quantified in the food leftovers for two of the reported outbreaks. Molecular typing of human and food isolates using pulsed-field gel electrophoresis (PFGE) and enterotoxin gene typing, confirmed the link between patients and the suspected foodstuffs. This also demonstrated the high diversity of CPS isolates both in the cases and in healthy persons carrying enterotoxin genes encoding emetic SEs for which no detection methods currently exist. For one outbreak, the investigation pointed out to the food handler who transmitted the outbreak strain to the food. Tools to improve staphylococcal food poisoning (SFP) investigations are presented.

Temperature and good sanitation practices are important factors for controlling growth of microorganisms. Fresh produce is stored at various temperatures to ensure quality and to prolong shelf life. When foodborne pathogens survive and grow on fresh produce at storage temperatures, then additional control strategies are needed to inactivate these pathogens. The aim of this study was to determine how temperatures associated with deciduous fruit processing and storage facilities (0.5, 4, and 21°C) affect the growth and/or survival of Escherichia coli O157:H7, Listeria monocytogenes , Salmonella enterica subsp. enterica serovar Typhimurium, and Staphylococcus aureus under different nutrient conditions (nutrient rich and nutrient poor) and on simulated contact surfaces (vinyl coupons). Information on the growth and survival of foodborne pathogens at specific deciduous fruit processing and storage temperatures (0.5°C) is not available. All pathogens except E. coli O157:H7 were able to survive on vinyl coupons at all temperatures. L. monocytogenes proliferated under both nutrient conditions independent of temperature. S. aureus was the pathogen least affected by nutrient conditions. The survival of foodborne pathogens on the vinyl coupons, a model system for studying surfaces in fruit preparation and storage environments, indicates the potential for cross-contamination of deciduous fruit products under poor sanitation conditions. Foodborne pathogens that can proliferate and survive at various temperatures under different nutrient conditions could lead to fruit cross-contamination. Temperature mismanagement, which could allow pathogen proliferation in contaminated fruit packing houses and storage environments, is a concern. Therefore, proper hygiene and sanitation practices, removal of possible contaminants, and proper food safety management systems are needed to ensure food safety.

Salmonella has been reported to be involved in several foodborne illness outbreaks, many of which resulted from consumption of raw tomatoes. This research aimed to optimize and evaluate the concentration of free chlorine (hypochlorous acid [HOCl]) used as a sanitizer to prevent cross-contamination of tomatoes inoculated with a cocktail of five rifampin-resistant Salmonella enterica serovars in a laboratory-based model flume system. Organic load, prepared using sterilized Scotts Premium Topsoil, was added in different quantities to the flume wash water to simulate real-world packinghouse conditions. In a typical packinghouse operation utilizing a recirculating flume system, the organic matter washed from tomato surfaces accumulates over time. In this study, different concentrations (0, 25, 50, 75, and 100 ppm) of HOCl were used as sanitizers under three organic load conditions (0, 650, and 1,000 mg/L chemical oxygen demand). Results showed that 100 ppm of HOCl was necessary to prevent Salmonella cross-contamination of uninoculated tomatoes in the model flume system in the presence of organic loading. Also, when treated with 100 ppm of HOCl, Salmonella levels were reduced by >4.5 log CFU per tomato from inoculated tomatoes in the presence of organic load. At 75 ppm of HOCl, Salmonella cross-contamination was prevented, but only in the absence of organic loading. In studies in which plate counts were negative, whole tomato enrichment studies were performed. No cross-contamination of uninoculated tomatoes was recorded when 100 ppm of HOCl was used, even in the presence of high organic load (1,000 mg/L chemical oxygen demand). Although sanitizer application reduces contamination on tomato surfaces, the primary function of sanitizers in the wash water is to prevent cross-contamination.

Palliative care, directed at improving the quality of life of terminally ill patients, is generally not aimed at any form of postponing or hastening death. It is possible that high quality palliative care could prevent requests for euthanasia. However, empirical evidence on this issue is scarce. In

Although therapeutic activity prevents functional decline and reduces mortality, little is known about typical levels of activity among intensive care unit (ICU) patients. This report of a preliminary study describes typical therapeutic activity and compares the use of two measures of activity in a small sample of chronically critically ill adults. Type, frequency, and duration of therapeutic activity were measured simultaneously with direct observation and actigraphy. The only consistent activity documented was turning (frequency: 3 turns/8 hours; duration: mean average of 11 minutes). Analysis demonstrated acceptable agreement between the two measures of activity for both frequency and duration of therapeutic but not for type of activity. Congruence between measures for duration of activity was also supported. This study provides information for investigators and practitioners who are interested in measuring or implementing therapeutic activity in selected critically ill adults.

[Prevention of pressure ulcers].

Even though they have not been diagnosed with a recognized disease, many people have or are at risk of contracting debilitating conditions. They can be referred to as being in the "ill-health zone." For example, many bedridden elderly develop pressure ulcers. The prevention and treatment of pressure ulcers should focus on two main factors: the role of pressure in the development of circulatory disorders; and increased dermal pH. In preventing the development of circulatory disorders resulting in pressure ulcers, using an air or polyurethane mattress is helpful. However, changing the mattress has little effect if the position of the bedridden person is not also changed regularly. To avoid an increase in dermal pH, caregivers should apply moisture-repellent cream and/or oil to the sacral region after careful cleansing. It is important that such preventive measures and treatment be performed daily, and caregivers should be educated on this need and subsequently monitored. Pharmacists have a role in caring for those in the ill-health zone.
