Investigating awareness, fear and control associated with norovirus and other pathogens and pollutants using best-worst scaling.

Pollutants found in the water and air environment represent an ever-growing threat to human health. Contact with some air-, water- and foodborne pathogens (e.g. norovirus) results in gastrointestinal diseases and outbreaks. For future risk mitigation, we aimed to measure people's awareness of waterborne and foodborne norovirus relative to other environment-associated pollutants (e.g. pesticides, bioaerosols, antibiotic resistant bacteria) and well-known risks (e.g. diabetes, dementia, terrorist attack). We used an online survey, which included a best-worst scaling component to elicit personal levels of control and fear prompted by norovirus relative to 15 other risks. There was a negative correlation between levels of fear vs. control for all 16 measured risks. Perceived infection control levels were higher amongst women compared to men and correlated with age and the level of qualification in both groups. Participants who had sought advice regarding the symptoms caused by norovirus appeared to have more control over the risks. Norovirus is associated with high levels of fear, however, the levels of control over it is low compared to other foodborne illnesses, e.g. Salmonella. Addressing this deficit in the public's understanding of how to control exposure to the pathogen in an important health need.

Role of healthcare practitioners in rotavirus disease awareness and vaccination - insights from a survey among caregivers.

An online survey was designed to assess awareness and understanding of Rotavirus (RV) gastroenteritis (RVGE), and knowledge and attitudes towards RV vaccination in Germany, Poland, Turkey, Indonesia, the Philippines and Thailand. Survey participants (n = 1500) comprised parents, expectant parents and guardians of children ≤5 years of age who have sole or joint responsibility for health and well-being decisions relating to their child, who were recruited from an online panel and provided their consent for study participation. Participants from most countries had a high level of awareness of RV infections (mean: 82%) and of those aware of RV, a mean of 61% participants were aware that RV was the most common cause of GE, however the majority (mean: 59%) were unaware that nearly every child would be infected with RVGE by the age of 5 years. Healthcare professional (HCP) recommendation was identified as the key driver for participants seeking vaccination (48%-75% of participants stated this reason, with results differing by country) followed by availability of RV vaccine in the national immunization program. Despite a high level of awareness of RVGE among participants, fostering knowledge regarding the difficulty of RVGE prevention, the risk of RV contraction and the associated serious consequences like dehydration is imperative to improve RV vaccination uptake. HCPs, being the primary influence on participants' decision on vaccination, are best suited to bridge existing knowledge gaps and recommend parents to vaccinate their children against RVGE.

Health-related quality of life of the parents of children hospitalized due to acute rotavirus infection: a cross-sectional study in Latvia.

BACKGROUND: Rotavirus is the leading cause of severe diarrhea in young children and infants worldwide, representing a heavy public health burden. Limited information is available regarding the impact of rotavirus gastroenteritis on the quality of life of affected children and their families. The objectives of study were to estimate the impact of rotavirus infection on health-related quality of life (HRQL), to assess the social and emotional effects on the families of affected children. METHODS: This study enrolled all (n = 527) RotaStrip®-positive (with further PCR detection) cases (0-18 years of age) hospitalized from April 2013 to December 2015 and their caregivers. A questionnaire comprising clinical (filled-in by the medical staff) and social (filled by the caregivers) sections was completed per child. RESULTS: Main indicators of emotional burden reported by caregivers were compassion (reported as severe/very severe by 91.1% of parents), worry (85.2%), stress/anxiety (68.0%). Regarding social burden, 79.3% of caregivers reported the need to introduce changes into their daily routine due to rotavirus infection of their child. Regarding economic burden, 55.1% of parents needed to take days off work because of their child's sickness, and 76.1% of parents reported additional expenditures in the family's budget. Objective measures of their child's health status were not associated with HRQL of the family, as were the parent's subjective evaluation of their child's health and some sociodemographic factors. Parents were significantly more worried if their child was tearful (p = 0.006) or irritable (p < 0.001). Parents were more stressful/anxious if their child had a fever (p = 0.003), was tearful (p < 0.001), or was irritable (p < 0.001). Changes in parents' daily routines were more often reported if the child had a fever (p = 0.02) or insufficient fluid intake (p = 0.04). CONCLUSION: Objective health status of the child did not influence the emotional, social or economic burden, whereas the parents' subjective perception of the child's health status and sociodemographic characteristics, were influential. A better understanding of how acute episodes affect the child and family, will help to ease parental fears and advise parents on the characteristics of rotavirus infection and the optimal care of an infected child.

Clinical Presentation of Acute Gastroenteritis in Children With Functional Abdominal Pain Disorders.

Visceral hypersensitivity and abnormal coping are common in children with functional abdominal pain disorders (FAPDs). Thus, it would be expected that children with visceral hypersensitivity would report more pain if their gut is acutely inflamed. The aim of the study was to compare clinical symptoms and somatization of children with and without FAPDs at time of an episode of acute gastroenteritis. Seventy children with acute gastroenteritis and their parents completed the Rome III Diagnostic Questionnaire for Pediatric Functional GI Disorders and the Children's Somatization Inventory. Twenty-one percent of children were diagnosed with an FAPD. Children with FAPDs showed significantly more nongastrointestinal somatic symptoms than children without FAPDs. There were no significant differences in abdominal pain, nausea, vomiting, or school absenteeism between both groups at time of consultation.

Quality of life impacts from rotavirus gastroenteritis on children and their families in the UK.

AIMS: Rotavirus vaccines (RV) are safe and effective but demand significant investment of healthcare resource. In countries with low mortality due to rotavirus, a key component to assessing cost-effectiveness is quantifying the Health Related Quality of Life (HRQoL) lost due to rotavirus acute gastroenteritis (RVAGE). METHODS: Families with children less than six years old with gastroenteritis were recruited from attendees to Bristol Children's Hospital Emergency Department. Stools were tested for viral causes of gastroenteritis. Children's HRQoL was assessed at presentation using Health Utilities Index 2 (HUI2) with visual analogue scale (VAS). The effect of the child's illness on the HRQoL of up to two adult carers was assessed using EQ-5D-5L. Families completed a daily symptom diary to assess time to recovery and within-family transmission. RESULTS: 127 families consented to take part, 84(65%) had rotavirus as the cause of illness. At the time of attendance, mean paediatric HRQoL with RVAGE was 0.74(HUI2) and 0.42(VAS). Primary/secondary carer's HRQoL was 0.68/0.80 (EQ5D) or 0.70/0.79 (VAS). The mean number of QALYs lost due to RVAGE was 3.1-3.5 per thousand children and 7.7-8.7 per thousand family units. In 52% of RVAGE families at least one other member developed a secondary case of gastroenteritis. For working parents, 69% missed work, for a mean of 2.8 days (95% CI 2.3-3.4). CONCLUSIONS: We have found the HRQoL loss associated with RVAGE in children and their carers to be significantly higher than estimates used for all RV medical attendances in UK cost-effectiveness calculations.

Family impact of Rotavirus Gastroenteritis in Taiwan and Vietnam: an Ethnographic Study.

BACKGROUND: Prior to the introduction of rotavirus vaccines, rotavirus was the leading cause of severe gastroenteritis in infants and young children, and it continues to be the leading cause in countries without vaccination programs. Rotavirus gastroenteritis results in substantial economic burden and has a pronounced effect on the family of those who are ill. Both in Taiwan and in Vietnam, rotavirus illness is viewed as a priority disease. This study assessed, in Taiwan and Vietnam, the impact of rotavirus gastroenteritis on the family among a group of parents whose children had recently been hospitalized for this illness. METHODS: In the first half of 2013, parents of children who had been hospitalized due to rotavirus infection were recruited from hospitals in Taiwan (n = 12) and Vietnam (n = 22), and participated in focus group sessions or in-depth ethnographic interviews. RESULTS: In both countries, the results point to a substantial burden on the parents concerning emotions and logistics of daily tasks, and to considerable disruptions of the family routine. Taiwanese parents reported satisfaction with the health care system, a great deal of effort to suppress emotions, a fair amount of knowledge about rotavirus, and little extra costs related to the illness. On the other hand, parents in Vietnam expressed concern about the emotional well-being of and the health care treatments for their children, were less knowledgeable regarding rotavirus infection, and experienced a substantial financial burden due to indirect costs that were related to accessing treatment. CONCLUSIONS: Families in Taiwan and Vietnam suffer from a considerable economic and emotional burden related to rotavirus gastroenteritis. One way to substantially reduce this burden is to provide universal and affordable rotavirus vaccination to susceptible children, especially since cost-effectiveness studies have demonstrated that universal vaccination would be safe and efficacious against severe rotavirus gastroenteritis in these countries.

[The polyglandular autoimmune syndrome--quality of life and family clustering]. / Das polyglanduläre Autoimmunsyndrom--Lebensqualität und familiäre Beteiligung.

BACKGROUND AND AIM: For patients with polyglandular autoimmune syndrome (PGA), data pertaining to familial clustering and quality of life are missing. Therefore, we performed a prospective and controlled study to collect this information. PATIENTS AND METHODS: Clinical and serological evaluation of 75 consecutively recruited patients with PGA (mean age 47,5 ± 15,3 years; 65,3% women) and their 108 relatives (mean age 33,13 ± 20,08 years; 65,7% women) was performed. Three validated questionnaires for psychosocial evaluation (quality of life short form 36 [SF-36], hospital anxiety and depression scale [HADS] and the Gießener Beschwerdebogen [GBB]) were answered by patients and relatives. RESULTS: 47 (62%) patients with PGA had type 1 diabetes and autoimmune thyroid disease. 56 (52%) of their relatives had an autoimmune disease whereas Hashimoto's thyroiditis and type-A-gastritis were the most prevalent endocrine and non-endocrine components. Thyroid peroxidase autoantibodies were most prevalent in patients and involved relatives. Compared to a German reference group, all scales of the SF-36 were markedly decreased in patients and involved relatives (p < 0.001). Anxiety and depression scales were pathologically increased in patients and relatives (p < 0.001). Also, all GBB scales were elevated for patients and relatives (p < 0.001). Patients with both glandular and non-glandular autoimmune diseases showed the most pathological psychosocial results. CONCLUSION: Familial clustering is high in patients with PGA. Quality of life and psychosocial status are poor in patients and involved relatives. Multidisciplinary management of the multiplex families in specialized centers is warranted.

Economic and psychosocial impact of rotavirus infection in Spain: a literature review.

Severe rotavirus gastroenteritis is common in children under 5 years of age. A literature review was performed to investigate the economic and psychosocial impact of rotavirus infection in children in this age group. We retrieved 56 articles on the economic burden of the disease in Europe, 18 of them reported data from Spain; 8 articles were retrieved analysing its psychosocial impact. In Spain, rotavirus is responsible for 14% to 30% of all cases of gastroenteritis, and a quarter of these require hospitalisation. It is also associated with high use of health care resources (emergency and primary care visits). Rotavirus gastroenteritis costs the Spanish national health system EUR 28 million a year and causes productivity loss in two-thirds of parents (mean of 4 days). Taking into account these costs, it was estimated that implementing universal vaccination could prevent 76% to 95% of hospital admissions due to rotavirus gastroenteritis, as well as reduce emergency and paediatric visits, nosocomial infections, and days missed from work (77% reduction). Rotavirus gastroenteritis also has a considerable psychosocial impact on the family, although it is difficult to compare results due to the diversity of study designs and the low specificity of the measurement tools used. It also causes high stress among parents, adding to their workload and adversely affecting their quality of life.

Impact of information leaflets on behavior of patients with gastroenteritis or tonsillitis: a cluster randomized trial in French primary care.

OBJECTIVE: To assess the impact of four patient information leaflets on patients' behavior in primary care. DESIGN: Cluster randomized multicenter controlled trial between November 2009 and January 2011. PARTICIPANTS: French adults and children consulting a participating primary care physician and diagnosed with gastroenteritis or tonsillitis. Patients were randomized to receive patient information leaflets or not, according to the cluster randomization of their primary care physician. INTERVENTION: Adult patients or adults accompanying a child diagnosed with gastroenteritis or tonsillitis were informed of the study. Physicians in the intervention group gave patients an information leaflet about their condition. Two weeks after the consultation patients (or their accompanying adult) answered a telephone questionnaire on their behavior and knowledge about the condition. MAIN MEASURES: The main and secondary outcomes, mean behavior and knowledge scores respectively, were calculated from the replies to this questionnaire. RESULTS: Twenty-four physicians included 400 patients. Twelve patients were lost to follow-up (3 %). In the group that received the patient information leaflet, patient behavior was closer to that recommended by the guidelines than in the control group (mean behavior score 4.9 versus 4.2, p < 0.01). Knowledge was better for adults receiving the leaflet than in the control group (mean knowledge score 4.2 versus 3.6, p < 0.01). There were fewer visits for the same symptoms by household members of patients given leaflets (23.4 % vs. 56.2 %, p < 0.01). CONCLUSION: Patient information leaflets given by the physician during the consultation significantly modify the patient's behavior and knowledge of the disease, compared with patients not receiving the leaflets, for the conditions studied.

Conceptual framework for health-related quality of life assessment in acute gastroenteritis.

BACKGROUND AND OBJECTIVES: To date, most trials in pediatric acute gastroenteritis have evaluated short-term clinical disease activity (eg, duration of diarrhea or vomiting, level of dehydration), laboratory outcomes (eg, rotavirus, norovirus), or a composite of these outcomes. Measuring health-related quality of life may also be important in evaluating the effect of interventions for acute gastroenteritis in children. The objectives of this study were to conduct individual interviews and, when possible, focus group discussions, with parents of children with acute gastroenteritis; to determine how parent and child quality of life is negatively affected by acute gastroenteritis; and, from the perspective of parents and children, to develop a conceptual framework for quality of life instrument specific to pediatric acute gastroenteritis. METHODS: We conducted interviews and focus groups with parents of children (3 months-5 years of age) given a diagnosis of gastroenteritis in a hospital emergency department. Interviews and focus groups were conducted to determine the effect of gastroenteritis on quality of life in parents and children (as perceived by the parents). RESULTS: Interviews and focus groups involving 25 parents suggested a conceptual framework that, for children, includes 2 domains (physical and emotional function) and 14 subdomains. For parents, our framework includes 3 domains (physical, emotional, and social function) with physical function including 4 subdomains, emotional function including 7 subdomains, and social function including 2 subdomains. The framework has been used to develop a preliminary quality of life questionnaire for parents and children. CONCLUSIONS: Acute gastroenteritis has an important adverse effect on health-related quality in both children and parents involving physical symptoms and restrictions in physical function and disturbed emotional function. Upon further research on the psychometric properties of the proposed questionnaires, future trials of effectiveness should consider measuring patient important outcomes such as health-related quality of life.

The impact of childhood acute rotavirus gastroenteritis on the parents' quality of life: prospective observational study in European primary care medical practices.

BACKGROUND: Rotavirus (RV) is the commonest cause of acute gastroenteritis in infants and young children worldwide. A Quality of Life study was conducted in primary care in three European countries as part of a larger epidemiological study (SPRIK) to investigate the impact of paediatric rotavirus gastroenteritis (RVGE) on affected children and their parents. METHODS: A self-administered questionnaire was linguistically validated in Spanish, Italian and Polish. The questionnaire was included in an observational multicentre prospective study of 302 children aged <5 years presenting to a general practitioner or paediatrician for RVGE at centres in Spain, Italy or Poland. RV infection was confirmed by polymerase chain reaction (PCR) testing (n = 264). The questionnaire was validated and used to assess the emotional impact of paediatric RVGE on the parents. RESULTS: Questionnaire responses showed that acute RVGE in a child adversely affects the parents' daily life as well as the child. Parents of children with RVGE experience worry, distress and impact on their daily activities. RVGE of greater clinical severity (assessed by the Vesikari scale) was associated with higher parental worries due to symptoms and greater changes in the child's behaviour, and a trend to higher impact on parents' daily activities and higher parental distress, together with a higher score on the symptom severity scale of the questionnaire. CONCLUSIONS: Parents of a child with acute RVGE presenting to primary care experience worry, distress and disruptions to daily life as a result of the child's illness. Prevention of this disease through prophylactic vaccination will improve the daily lives of parents and children.

The stress (of an) epidemic.

We examined the consequences of being exposed to an outbreak of the Norwalk virus at a small university. Data from 422 undergraduates supported a model in which the experience of symptoms and perceptions of the university's response to the outbreak predicted fear of future contamination. In turn, fear predicted strain and enhanced hygiene practices. Results are consistent with a model of disease outbreak as a traumatic stressor, and implications for organizations dealing with disease outbreaks are discussed.

Risk of functional gastrointestinal disorders in U.S. military following self-reported diarrhea and vomiting during deployment.

INTRODUCTION: Military personnel are frequently deployed to regions of the world with high travelers' diarrhea (TD) rates. Pathogens associated with TD have been linked to several post-infectious sequelae, including functional gastrointestinal disorders (FGD), such as irritable bowel syndrome (IBS) and functional dyspepsia. Furthermore, stress associated with deployment may potentiate the increased FGD risk. AIM: We sought to assess whether self-reported diarrhea, vomiting, and stressors during deployment were associated with increased FGD risk. METHODS: Using active duty military medical encounter data from the Defense Medical Surveillance System (DMSS), we conducted a matched case-control study to assess the odds of FGD (IBS, functional constipation, functional diarrhea, dyspepsia) following self-reported diarrhea or vomiting during deployment. Only first-time deployers with detailed self-reporting of deployment-related exposures from 2008 and 2009 were included. Univariate and multivariate analyses were performed. RESULTS: A total of 129 cases of FGD were identified, with the following distribution: constipation (n = 67), dyspepsia (n = 15), IBS (n = 22), and overlapping disorders (n = 25). Diarrhea and/or vomiting during deployment were significantly associated with the development of FGD. Other demographic factors were also associated with variable risk. We found no consistent effect of war-related stressors or non-combat-related correlates of stress. CONCLUSIONS: Deployment-related TD is common in deployed military personnel and is associated with an increased risk of several FGD. When considering effective countermeasures and mitigation strategies, both the acute effects and chronic sequelae of enteric infections should be considered. Increased emphasis on existing and novel primary prevention strategies are needed, as well as outcome studies among those developing these conditions.

[Peculiarities of quality of life in children with chronic gastroduodenitis].

AIM OF INVESTIGATION: To study quality of life (QL) peculiarities in children with chronic gastroduodenitis, Helicobacter pylori positive, in different stages of the disease. METHODS: Quality of life in 60 children (average age--13.06 +/- 1.2 years) with chronic gastroduodenitis was investigated with using adopted SF-36 questionnaire in period of exacerbation of the disease, in 6 weeks after treatment and in period of remission (in 6 months after treatment). 22 healthy children (average age--12.74 +/- 1.14 years) had been taken as a comparison group. RESULTS: Quality of life in children with chronic gastroduodenitis in exacerbation period was significantly worse (p < 0.05) than in healthy children. The more affected scores were the Role physical (RP), Bodily pain with the scores of healthy children. Presence astenic signs in period of remission (in 6 months after treatment) led to worsening of quality of life; the scores were the same and partly worse then before treatment. Applying of neurometabolic therapy improved psycho-emotional status and quality of life. CONCLUSIONS: Quality of life in children with chronic gastroduodenitis was changed with the period of diseases. Initially low scores had tendency to improvement after treatment. In remission period quality of life was mainly depended on peculiarities of psycho-emotional status. Astenic signs led to worsening of quality of life in children with remission of chronic gastroduodenitis. Neurometabolic treatment in this period improved both psycho-emotional status and quality of life.

Health-related quality of life lost to rotavirus-associated gastroenteritis in children and their parents: a Canadian prospective study.

We estimated the impact of rotavirus-associated gastroenteritis (RGE) on health-related quality of life of children and parents as background for economic evaluation of rotavirus vaccines. A total of 186 new cases of RGE in children <36 months old were recruited from physician and pediatric clinics and followed up for 2 weeks. Our results show that RGE impacts the health-related quality of life of children and parents adversely.

[Survey about the perception of the gastroenteritis and the infection due to rotavirus by the mothers in France]. / Enquête sur la perception de la gastro-entérite et de l'infection à Rotavirus par les mères en France.

AIM: To describe the perception of the acute gastroenteritis (AGE) and the interest for the vaccination of the AGE due to Rotavirus. MATERIAL AND METHODS: Observational investigation realized by phone by the IPSOS institute, with 1002 French women of 18 years and more, constituting a representative national sample, having at least a child below 2 years, between 7 and January 31st, 2008. RESULTS: AGE is mainly considered by the mothers questioned as a grave pathology (43.1%) or very grave (51.3%) for the children below 2 years. This perception is bound to the symptoms and to the complications known for the disease. For the questioned mothers, the AGE comes along very often or often with diarrheas (97.2%), vomits (94.3%) or dehydration (94%). Hospitalizations are also perceived as frequent. The quasi-totality of the questioned women (98.3%) considers finally that it is about a very contagious disease (75.4%) or rather contagious (22.8%). The AGE at the child below 2 years provoke very frequently a medical consultation (91.8%), during which some solutions of oral rehydration are prescribed in six cases on 10 (62%). The questioned mothers are for the greater part favorable (86.3%) to a drinkable vaccine to prevent the AGE due to Rotavirus, and 88.1% say that they would intend to protect their child with this vaccine. CONCLUSION: The questioned mothers know the potential gravity of the AGE and a very wide majority of them (86.3%) declare themselves favorable to the prevention of the AGE at Rotavirus by the vaccination.

Risk markers for both chronic fatigue and irritable bowel syndromes: a prospective case-control study in primary care.

BACKGROUND: Fatigue syndromes and irritable bowel syndrome (IBS) often occur together. Explanations include being different manifestations of the same condition and simply sharing some symptoms. METHOD: A matched case-control study in UK primary care, using data collected prospectively in the General Practice Research Database (GPRD). The main outcome measures were: health-care utilization, specific symptoms and diagnoses. Risk markers were divided into distant (from 3 years to 1 year before diagnosis) and recent (1 year before diagnosis). RESULTS: A total of 4388 patients with any fatigue syndrome were matched to two groups of patients: those attending for IBS and those attending for another reason. Infections were specific risk markers for both syndromes, with viral infections being a risk marker for a fatigue syndrome [odds ratios (ORs) 2.3-6.3], with a higher risk closer to onset, and gastroenteritis a risk for IBS (OR 1.47, compared to a fatigue syndrome). Chronic fatigue syndrome (CFS) shared more distant risk markers with IBS than other fatigue syndromes, particularly other symptom-based disorders (OR 3.8) and depressive disorders (OR 2.3), but depressive disorders were a greater risk for CFS than IBS (OR 2.4). Viral infections were more of a recent risk marker for CFS compared to IBS (OR 2.8), with gastroenteritis a greater risk for IBS (OR 2.4). CONCLUSIONS: Both fatigue and irritable bowel syndromes share predisposing risk markers, but triggering risk markers differ. Fatigue syndromes are heterogeneous, with CFS sharing predisposing risks with IBS, suggesting a common predisposing pathophysiology.

[Assessment of workload in pediatric emergency units due to acute gastroenteritis during the epidemic season in France]. / Evaluation de la charge de travail induite aux urgences pédiatriques par les gastroentérites aiguës en période épidémique.

OBJECTIVE: The aim of this study was to assess the burden of medical and paramedical activities related to the management of acute gastroenteritis (AGE) cases in France. METHODS: An observational, multicenter study was carried out in 23 French pediatric emergency units. Each unit was requested to include the first 25 children less than five years of age, consulting for AGE during the epidemic season. RESULTS: A total of 443 children was included between January and April 2007. The median age was 13 months. Symptoms had been persisting for an average of 2.7 days, and 60.7% of patients had already consulted. In 62.6% of cases, oral rehydration solution (ORS) had been prescribed. The median waiting time in the EU was 15 minutes. The median time spent by a health care professional with a child was 55 minutes (30 minutes for paramedical care and 25 minutes for medical care). The length of these visits increased significantly (p<0.0001) if children presented with signs of dehydration or behavioral changes. The child's age had no significant impact. Rehydration in the EU was 70% oral rehydration, 16% parenteral rehydration (8% were combined). Among the children, 37% were discharged after consultation in the EU, 39% after observation, and 24% were hospitalized. 90% of the children who were given a prescription on discharge were prescribed at least one ORS (n=333). CONCLUSION: The time spent by a health care professional with a child presenting with acute gastroenteritis could cause organizational problems during an epidemic outbreak.
