Higher Heart Failure Risk Seen in Some Cancers
Some people treated for breast cancer or lymphoma have a higher risk of developing congestive heart failure than people who haven’t had cancer, a new study shows. As this Cancer Currents blog post reports, the risk persisted for at least 20 years.

Is higher risk sex common among male or female youths?
Berhan, Yifru; Berhan, Asres
2015-01-01
There are several studies that showed the high prevalence of high-risk sexual behaviors among youths, but little is known how significant the proportion of higher risk sex is when the male and female youths are compared. A meta-analysis was done using 26 countries' Demographic and Health Survey data from and outside Africa to make comparisons of higher risk sex among the most vulnerable group of male and female youths. Random effects analytic model was applied and the pooled odds ratios were determined using Mantel-Haenszel statistical method. In this meta-analysis, 19,148 male and 65,094 female youths who reported to have sexual intercourse in a 12-month period were included. The overall OR demonstrated that higher risk sex was ten times more prevalent in male youths than in female youths. The practice of higher risk sex by male youths aged 15-19 years was more than 27-fold higher than that of their female counterparts. Similarly, male youths in urban areas, belonged to a family with middle to highest wealth index, and educated to secondary and above were more than ninefold, eightfold and sixfold at risk of practicing higher risk sex than their female counterparts, respectively. In conclusion, this meta-analysis demonstrated that the practice of risky sexual intercourse by male youths was incomparably higher than female youths. Future risky sex protective interventions should be tailored to secondary and above educated male youths in urban areas.
Current State of the Art: Management of Higher Risk Myelodysplastic Syndromes.
Komrokji, Rami S
2016-08-01
The higher risk myelodysplastic syndrome (MDS) patients, defined by the International Prognostic Scoring System (IPSS) as intermediate-2 or high-risk groups, compromise a third of MDS patients who have an expected survival of less than 1.5 years. Our ability to better define higher risk MDS improved with the proposal of new clinical risk models such as the revised IPSS and by integration of molecular data, including somatic gene mutations. Allogeneic hematopoietic stem-cell transplantation (AHSCT) remains the only curative option. In higher risk MDS patients, proceeding early with AHSCT is associated with maximum survival gain. The decision to pursue AHSCT is individualized according to disease risk, comorbidities, and functional status. The role of therapy before AHSCT remains controversial, and the role of post-AHSCT maintenance is evolving. Hypomethylating agents are the only medications that alter the natural history of the disease. Azacitidine is the only drug reported to improve overall survival in higher risk MDS patients. Appropriate use and assessment of response is key for assuring patients benefit of such limited options. Treatment after failure of hypomethylating agents is an unmet need. The role of detectable somatic gene mutations in prognosis and tailoring therapy continue to emerge. Copyright © 2016 Elsevier Inc. All rights reserved.
Radon risks: Attitudes, perceptions and actions. Risk communication series. Final report
Energy Technology Data Exchange (ETDEWEB)
Sjoeberg, L.
1989-08-01
As many as 8 million homes in the United States may have elevated radon levels, with accompanying lung cancer risks several orders of magnitude higher than for most other environmental risks. The U.S. Environmental Protection Program (EPA) does not have clear regulatory authority over radon, so has relied on an information program. Less than 5% of homes have been tested, which is disappointing from a public health stance. The report summarizes the available research on communicating about the risk from radon from the perspective of a psychologist. The research results are critiqued to draw practical conclusions for radon policy and suggest the most important topics for further risk communication research.
Quality of reporting and risk of bias in therapeutic otolaryngology publications.
Kaper, N M; Swart, K M A; Grolman, W; Van Der Heijden, G J M G
2018-01-01
High-quality trials have the potential to influence clinical practice. Ten otolaryngology journals with the highest 2011 impact factors were selected and publications from 2010 were extracted. From all medical journals, the 20 highest impact factor journals were selected, and publications related to otolaryngology for 2010 and 2011 were extracted. For all publications, the reporting quality and risk of bias were assessed. The impact factor was 1.8-2.8 for otolaryngology journals and 6.0-101.8 for medical journals. Of 1500 otolaryngology journal articles, 262 were therapeutic studies; 94 had a high reporting quality and 5 a low risk of bias. Of 10 967 medical journal articles, 76 were therapeutic studies; 57 had a high reporting quality and 8 a low risk of bias. Reporting quality was high for 45 per cent of otolaryngology-related publications and 9 per cent met quality standards. General journals had higher impact factors than otolaryngology journals. Reporting quality was higher and risk of bias lower in general journals than in otolaryngology journals. Nevertheless, 76 per cent of articles in high impact factor journals carried a high risk of bias. Better reported and designed studies are the goal, with less risk of bias, especially in otolaryngology journals.
Higher-order risk preferences in social settings.
Heinrich, Timo; Mayrhofer, Thomas
2018-01-01
We study prudence and temperance (next to risk aversion) in social settings. Previous experimental studies have shown that these higher-order risk preferences affect the choices of individuals deciding privately on lotteries that only affect their own payoff. Yet, many risky and financially relevant decisions are made in the social settings of households or organizations. We elicit higher-order risk preferences of individuals and systematically vary how an individual's decision is made (alone or while communicating with a partner) and who is affected by the decision (only the individual or the partner as well). In doing so, we can isolate the effects of other-regarding concerns and communication on choices. Our results reveal that the majority of choices are risk averse, prudent, and temperate across social settings. We also observe that individuals are influenced significantly by the preferences of a partner when they are able to communicate and choices are payoff-relevant for both of them.

Method: The study consisted of the administration of two instruments, one for the characterization of the sample and the other for assessing psychosocial risk factors — the Copenhagen Psychosocial Questionnaire — consisting of 76 items (5-point Likert scale, distributed in five dimensions, which measure indicators of exposure to psychosocial risks and their effects. Results: The study included 59 teachers, mostly men (50.8%, aged between 41 - 50 years (45.8%, with master's degree (59%, assistant professors (47.5%; with a stable employment relationship (68%, years of service between 14-17 years (18.7% and teaching between 11 - 17 hours a week (64.4%. The analysis of the various subscales revealed a psychosocial risk, showing that teachers are in a situation of vulnerability. There were significant differences between the risks experienced in public higher education and those experienced in private higher education. Gender, age, academic background, and professional category influenced the type of psychosocial risk. Conclusions: The study confirms the importance of the evaluation of psychosocial risk factors in the exercise of the teaching profession in higher education. It is recognized that it is necessary to assess and manage psychosocial risks in order to promote healthy working conditions, ensure respect and fair treatment, and encourage the promotion of work / family life balance, in order to minimize psychosocial risks and situations of vulnerability in higher education teachers.

Full Text Available Disasters are one of the most important challenges which must be considered by every management system. Higher education centers have high disaster risk because of their risk factors (existence of historical and scientific documents and resources and expensive laboratory equipment in these centers emphasizes the importance of disaster management. Moreover, the existence of young volunteers of human resources in universities urges the necessity of making these people familiar with disaster management rules and responses in emergency conditions. Creating appropriate tools for disaster management assessment makes it correct and precise in higher education systems using the presented conceptual model. The present model was planned so as to cover three phases which exist before, during, and after disaster. Studies were performed in one of the largest higher education centers in Tehran: Science and Research Branch of Islamic Azad University Campus. Results showed high-risk disasters in these centers which must be taken into consideration continuously. The objective of this study was to create appropriate patterns of disaster risk management in these centers.
Risk management in higher education and research in the Netherlands

This study examines risk in higher education and research on the basis of a classification into three domains. The practical utility of this division into three domains is that it makes it easier to see what risks are unique to higher education (custodianship of knowledge), what risks are dependent
MODERN RISK MEASURES FOR INDIVIDUAL HIGHER EDUCATION INVESTMENT RISK EVALUATION

Full Text Available One of the reasons why people get degree and participate in organized education is that they want to raise their human capital or signal their inner abilities to future employers by sorting themselves out. In both cases they can expect return to their investment, because they can expect higher life-time earnings than those who do not have degree. In this paper we will refer this activity as higher education investment or education investment. In this paper the investment of the state into educating their citizens will not be considered. The question of this paper will develop the findings of Vona (2014. I suggested to introduce modern risk measures because individual risk-taking became a serious question. It was considered that modern risk measures can help to solve some issues with the relation of investment and risk. However before applying some measures from a different field of science, namely investment finance and financial mathematics, to another, economics of education, there must be a very careful consideration, because there are debate over these measures applicability even on their field of science. Value at Risk is not coherent and Expected Shortfall is only one of a great deal of possible tail loss measures. For this reason it will be discussed in detail how should we should adopt the measures, what kind of data is necessary for calculating this risk measures and what kind of new insight they can bring. With the aid of a numerical example it will be shown that with expected shortfall measure we can reflect some large losses, and potential high value of diversification. We show the value at risk based measure is not coherent and this means it points out something different in this environment. It is can be an indicator of loss in opportunities for high end returns.

Purpose To compare risk for teen pregnancies between children living in poverty with no Child Protection Services (CPS) report history, and those in poverty with a history of CPS report. Methods Children selected from families in poverty, both with and without CPS report histories were prospectively followed from 1993–2009 using electronic administrative records from agencies including child protective services, emergency departments, Medicaid services and juvenile courts. A total of 3281 adolescent females were followed until age 18. Results For teens with history of poverty only, 16.8% had been pregnant at least once by age 17. In teens with history of both poverty and report of child abuse or neglect, 28.9% had been pregnant at least once by age 17. While multivariate survival analyses revealed several other significant factors at the family and youth services levels, a report of maltreatment remained significant (about a 66% higher risk). Conclusions Maltreatment is a significant risk factor for teen pregnancy among low income youth even after controlling for neighborhood disadvantage, other caregiver risks and indicators of individual emotional and behavioral problems.

To examine whether day napping or short night sleeping is associated with higher risk of diabetes. This was a prospective study of hours of day napping and night sleeping assessed in 1996-1997 in relation to diabetes diagnosed between 2000 and 2006 (n = 10,143) among 174,542 participants in the National Institutes of Health (NIH)-AARP Diet and Health Study. Odds ratios (ORs) and 95% CI were derived from multivariate logistic regression models. Longer day napping was associated with a higher risk of diabetes. After adjustment for potential confounders, ORs were 1.23 (95% CI 1.18-1.29) for those reporting or =1 h of napping compared with individuals who did not nap (P(trend) or =9 h. In both analyses, additional adjustment for BMI only modestly attenuated the associations. Further analysis showed a statistically significant interaction between hours of napping and sleeping on diabetes (P(interaction) napping, only short night sleeping was associated with higher occurrence of diabetes, whereas among those with > or =1 h of napping, both long and short sleeping was associated with higher risk. Day napping and short night sleeping are associated with higher risk of diabetes. The association between sleep duration and diabetes may be modified by napping habit.
Prevalence and Risk Factors for Self-Reported Violence of Osaka and Seattle Male Youths
Bui, Laura; Farrington, David P.; Ueda, Mitsuaki; Hill, Karl G.
2013-01-01
Traditionally, Japan has been regarded as a country with low crime. Comparative research has given insights into the extent of similarities and differences in crime between America and Japan. The importance of these studies is the examination of whether Western-established criminological knowledge is applicable to non- Western societies like Japan. Unfortunately, comparative self-report studies involving Japan and investigating youth offending are scarce. The current study investigates risk factors and self-reports of violence from Osaka and Seattle male youths. The findings reveal that Japanese male youths self-report a higher prevalence of violence than Seattle male youths. Risk factors for violence, issues of comparability, and prevalence versus strength of relationships of risk factors are examined. It is concluded that the higher prevalence of violence in Osaka is primarily a function of the higher prevalence of troubled peers and risk taking. The findings call for replication of this type of comparative research. PMID:24013769

We investigated which adolescent health risk behaviors are of concern to parents generally, according to adolescent age, gender, and in the context of perceived risk. We compared adolescent and parent reports of the presence of health-risk behaviors and factors predicting agreement. Three hundred adolescents aged 13 to 18 years (mean, 14.5 years; 52% female) who presenting for well care completed an electronic screening tool used to assess health-risk behaviors. Parents completed parallel measures of their child's behavior and parental concern. Adolescent and parent reports were compared using McNemar test. Hierarchical linear regression was used to examine predictors of agreement. High parental concern was most commonly reported for screen time and diet. When parents identified their adolescent as at-risk, high parental concern was near universal for mental health but less commonly reported for substance use. There were no differences in parental concern according to adolescent gender. Parents of older adolescents expressed more concern regarding physical activity and alcohol. Compared with adolescents, parents were more likely to report risk regarding anxiety, fruit and vegetable consumption, and physical activity, and less likely to report risk regarding screen time, sleep, and marijuana use. Younger adolescent age and higher family relationship quality were predictive of stronger parent-adolescent agreement. Parents in well-care visits commonly have concerns about adolescent lifestyle behaviors. Although parents are more likely to report concern when they know about a behavior, parental concern is not always aligned with parental awareness of risk, particularly for substance use. Parent report of higher prevalence of some risk behaviors suggests their input might assist in risk identification. Copyright © 2017 Academic Pediatric Association. Published by Elsevier Inc.

To explore whether young adolescents consuming alcohol and energy drinks combined were more likely to report negative behavioural outcomes than their peers who drink only one type of these beverages or are abstinent. We analysed data on a representative sample of Slovak adolescents 8502 adolescents (mean age 13.21, 49.4 % boys) from the 2014 Health Behaviour in School-aged Children cross-sectional study. We assessed the associations of alcohol and energy drinks consumption with negative outcomes and their potential synergy, as measured by the synergy index (SI). Adolescents consuming both alcohol and energy drinks were at higher risk of negative behavioural outcomes than their peers who drank only alcohol or energy drinks or were non-consumers. Consumers of alcohol and energy drinks were highly prone to be involved in fighting-the joint association of alcohol and energy drinks consumption was greater than sum of its associations separately in relation to fighting (SI 1.49; 95 % confidence interval 1.03-2.16). Preventive strategies should aim at increasing awareness of negative behavioural outcomes-especially aggressive behaviour associated with alcohol and energy drinks consumption among young adolescents.

Socioeconomic gradients in health behavior are pervasive and well documented. Yet, there is little consensus on their causes. Behavioral ecological theory predicts that, if people of lower socioeconomic position (SEP) perceive greater personal extrinsic mortality risk than those of higher SEP, they should disinvest in their future health. We surveyed North American adults for reported effort in looking after health, perceived extrinsic and intrinsic mortality risks, and measures of SEP. We examined the relationships between these variables and found that lower subjective SEP predicted lower reported health effort. Lower subjective SEP was also associated with higher perceived extrinsic mortality risk, which in turn predicted lower reported health effort. The effect of subjective SEP on reported health effort was completely mediated by perceived extrinsic mortality risk. Our findings indicate that perceived extrinsic mortality risk may be a key factor underlying SEP gradients in motivation to invest in future health.

Most studies regarding xerostomia focus on elderly people. Therefore, the authors conducted a study of dental patients 18 years or older to determine the prevalence of self-reported xerostomia and associated risk factors. The authors sent a total of 2,200 questionnaires to four dental clinics to assess patients' self-reported xerostomia. They also collected sociodemographic data and information regarding personal behavior. They used logistic regression models to estimate odds ratios (OR) and 95 percent confidence intervals (CI) to explore the relationship between self-reported xerostomia and risk factors that reasonably might be expected to be associated with self-reported xerostomia. The overall prevalence of xerostomia in participants was 7 percent. Participants with burning-mouth sensations were associated with having higher odds of experiencing dry mouth (OR, 2.1; 95 percent CI, 0.9-5.2). Participants 51 years or older were significantly more likely to report having dry mouth than were younger participants (P xerostomia increased with increasing numbers of medications patients reported using. The authors found that medication use and age were highly significant risk factors for dental patients reporting xerostomia. Clinicians should interview their patients carefully regarding their use of medications and provide proper oral health care to improve xerostomia resulting from medication use.
Pregnant Women in Sport Climbing - Is there a Higher Risk for Preterm Birth?
Drastig, Jan; Hillebrandt, David; Rath, Werner; Küpper, Thomas
2017-02-01
Sport climbing is a popular recreational sport with an increasing proportion of female athletes. International recommendations emphasize the physical and mental benefits of regular sport activity during any uncomplicated pregnancy. In this context, sport climbing is associated with a high risk potential.The aim of this study was to examine if there is a higher risk for preterm birth in active climbing athletes.Original manuscript.A retrospective self-report online survey in the German language collected data between September 2012 and November 2013. In addition to anthropometric and demographic data, data on climbing experience, preferred climbing discipline, skill level and changes of climbing habits during pregnancy, known risk factors for preterm birth and information on delivery and the newborn were requested. The rate of preterm birth of the survey was tested with Fisher's exact test with information from the German Federal Statistical Office.Sample size was 32. 72% had a university degree, 81% were primiparous, all were singleton pregnancies. A 33 rd questionnaire was excluded because of described preeclampsia. Age ranged between 21 and 39 years, climbing experience before pregnancy between 2 and 24 years, and skill level before pregnancy between 4 and 7 on the UIAA scale (International Climbing and Mountaineering Federation). Half of the women climbed until the 36 th week and 90% adjusted their climbing habits mostly by reducing climbing difficulty and doing more top roping. 2 preterm births in the 36 th week of gestation were found (2 from 15, p=0.36). According to the data from the German Federal Statistical Office, 8.9% births in the year 2013 in Germany were preterm.This is the first study investigating the risk of preterm birth in recreational sport climbing athletes. No significantly higher proportion of preterm birth could be found. Limitations are small sample size and high social status of participants. What is known about the subject: Sport

Occult cancers' reported rates vary from 2-12% and serous tubal intraepithelial carcinomas (STICs) have been identified in 3-12% of the prophylactically removed tubes of women carrying a BRCA mutation. The aim of this study was to evaluate the incidence of tubal minor epithelial atypia (STIL), STIC, and occult invasive cancer and to evaluate the cancer-specific mortality in a prospective series of women at higher risk of ovarian and breast cancer undergoing risk-reducing salpingo-oophorectomy (RRSO) n a tertiary cancer center. A series of RRSO specimens (including endometrial biopsy) from women carrying a BRCA mutation, BRCA-unknown and BRCA-negative were collected between January 1998 and April 2016 at the Division of Gynecology at the European Institute of Oncology. Inclusion criteria were: asymptomatic women who had a negative gynecologic screening within 3 months prior to RRSO. Exclusion criteria were: women with ovarian/tubal cancer prior to RRSO. A total of 411 women underwent RRSO. Median age at RRSO was 47.0 years (range=32-70 years); 75.2% had a history of breast cancer. Fifteen women were diagnosed with an occult cancer (7 STIC, 4 invasive cancers, 2 breast cancers metastatic to the adnexa, 2 endometrial cancer) (3.6%). Sixteen showed a STIL (3.9%). When excluding cases with preoperative positive markers, the occult invasive cancer rate drops to 1.5%. Our study, covering an 18-year period, shows a substantial low risk of occult cancer among a high-risk population of women undergoing RRSO. Our data still support the indication for RRSO in higher-risk patients. An endometrial biopsy should also be routinely obtained as it raises the chances of detecting occult endometrial cancers that may be otherwise missed.

Why does society accept a higher risk for alcohol than for other voluntary or involuntary risks?
Rehm, Jürgen; Lachenmeier, Dirk W; Room, Robin
2014-10-21
Societies tend to accept much higher risks for voluntary behaviours, those based on individual decisions (for example, to smoke, to consume alcohol, or to ski), than for involuntary exposure such as exposure to risks in soil, drinking water or air. In high-income societies, an acceptable risk to those voluntarily engaging in a risky behaviour seems to be about one death in 1,000 on a lifetime basis. However, drinking more than 20 g pure alcohol per day over an adult lifetime exceeds a threshold of one in 100 deaths, based on a calculation from World Health Organization data of the odds in six European countries of dying from alcohol-attributable causes at different levels of drinking. The voluntary mortality risk of alcohol consumption exceeds the risks of other lifestyle risk factors. In addition, evidence shows that the involuntary risks resulting from customary alcohol consumption far exceed the acceptable threshold for other involuntary risks (such as those established by the World Health Organization or national environmental agencies), and would be judged as not acceptable. Alcohol's exceptional status reflects vagaries of history, which have so far resulted in alcohol being exempted from key food legislation (no labelling of ingredients and nutritional information) and from international conventions governing all other psychoactive substances (both legal and illegal). This is along with special treatment of alcohol in the public health field, in part reflecting overestimation of its beneficial effect on ischaemic disease when consumed in moderation. A much higher mortality risk from alcohol than from other risk factors is currently accepted by high income countries.

Objectives: The delimitation of risk management models and uncertainties in fundamental research. Research method: Fundamental research study directed to identify the relevant risks’ models presented in entities’ financial statements. Uncertainty is one of the fundamental coordinates of our world. As showed J.K. Galbraith (1978, the world now lives under the age of uncertainty. Moreover, we can say that contemporary society development could be achieved by taking decisions under uncertainty, though, risks. Growing concern for the study of uncertainty, its effects and precautions led to the rather recent emergence of a new science, science of hazards (les cindyniques - l.fr. (Kenvern, 1991. Current analysis of risk are dominated by Beck’s (1992 notion that a risk society now exists whereby we have become more concerned about our impact upon nature than the impact of nature upon us. Clearly, risk permeates most aspects of corporate but also of regular life decision-making and few can predict with any precision the future. The risk is almost always a major variable in real-world corporate decision-making, and managers that ignore it are in a real peril. In these circumstances, a possible answer is assuming financial discipline with an appropriate system of incentives.

This retrospective analysis defined and described patterns and predictors of weight change during treatment in children with acute lymphocytic leukemia (ALL) with high-risk features who received treatment on Children's Cancer Group protocol CCG 1961. Patients (1,638) were enrolled in CCG 1961 from November 1996 to May 2002. Weight was measured as BMI percent (%), specific for age and gender, and defined as 100 x ln(BMI/median BMI). By the end of treatment, 23% of children were obese (BMI >or=95%), compared with 14% at diagnosis. Children who received post-induction intensified therapy (arms C, D, SER with Doxorubicin or Idarubicin) had higher gastrointestinal toxicities and lower BMI% from consolidation through interim maintenance 1. BMI% then increased for all arms between delayed intensification and maintenance 1 or 2. Children who were of Black or Hispanic race, obese at diagnosis, or who had grade 3 or 4 pancreatitis/glucose toxicities during induction had higher BMI% throughout treatment. Children were more likely to be obese at the end of the study if they were aged 5-9 years at diagnosis or female gender. Cranial radiation was not a predictor of obesity. Successful treatment of higher risk childhood ALL was associated with obesity, independent of cranial irradiation. The beginning of maintenance therapy may be the best time to intervene with nutritional and behavioral interventions, particularly for children who are obese or aged 5-9 years at diagnosis, female, Black or Hispanic, or those with metabolic toxicities during induction.

Among a random sample of emergency department (ED) patients, we sought to determine the extent to which reported risk for human immunodeficiency virus (HIV) is related to ever having been tested for HIV. A random sample of patients (aged 18-64 years) from an adult, urban, northeastern United States, academic ED were surveyed about their history of ever having been tested for HIV and their reported HIV risk behaviors. A reported HIV risk score was calculated from the survey responses and divided into 4 levels, based on quartiles of the risk scores. Pearson's X(2) testing was used to compare HIV testing history and level of reported HIV risk. Logistic regression models were created to investigate the association between level of reported HIV risk and the outcome of ever having been tested for HIV. Of the 557 participants, 62.1% were female. A larger proportion of females than males (71.4% vs 60.6%; P history of injection-drug use, were associated with prior HIV testing for both genders. In the logistic regression analyses, there was no relationship between increasing level of reported HIV risk and a history of ever having been tested for HIV for males. For females, a history of ever having been tested was related to increasing level of reported risk, but not in a linear fashion. The relationship between reported HIV risk and history of testing among these ED patients was complex and differed by gender. Among these patients, having greater risk did not necessarily mean a higher likelihood of ever having been tested for HIV.

Personalised breast screening requires assessment of individual risk of breast cancer, of which one contributory factor is weight. Self-reported weight has been used for this purpose, but may be unreliable. We explore the use of volume of fat in the breast, measured from digital mammograms. Volumetric breast density measurements were used to determine the volume of fat in the breasts of 40,431 women taking part in the Predicting Risk Of Cancer At Screening (PROCAS) study. Tyrer-Cuzick risk using self-reported weight was calculated for each woman. Weight was also estimated from the relationship between self-reported weight and breast fat volume in the cohort, and used to re-calculate Tyrer-Cuzick risk. Women were assigned to risk categories according to 10 year risk (below average =8%) and the original and re-calculated Tyrer-Cuzick risks were compared. Of the 716 women diagnosed with breast cancer during the study, 15 (2.1%) moved into a lower risk category, and 37 (5.2%) moved into a higher category when using weight estimated from breast fat volume. Of the 39,715 women without a cancer diagnosis, 1009 (2.5%) moved into a lower risk category, and 1721 (4.3%) into a higher risk category. The majority of changes were between below average and average risk categories (38.5% of those with a cancer diagnosis, and 34.6% of those without). No individual moved more than one risk group. Automated breast fat measures may provide a suitable alternative to self-reported weight for risk assessment in personalized screening.

Thrombocytosis following splenectomy is a common occurrence. Whether this thrombocytosis leads to a higher risk for venous thromboembolism (VTE) remains unclear. This investigation aimed to determine if splenectomy increases the risk for VTE. This was a prospective study conducted in the SICU between 1/2011 and 11/2013 investigating the VTE risk in patients undergoing a splenectomy compared with those undergoing any other abdominal procedure. In total 2503 patients were admitted to the SICU: 37 (2%) after a splenectomy and 638 (26%) after any other abdominal surgery. Splenectomy patients had a higher incidence of VTE compared to patients undergoing any other abdominal procedure (29.7% vs. 12.1%, p splenectomy was associated with a higher adjusted risk for VTE compared to the no-splenectomy group (AOR [95% CI]: 2.6 [1.2, 5.9], p = 0.02). Reactive thrombocytosis did not predict the development of VTE. Splenectomy increases the risk for VTE, however reactive thrombocytosis is not associated with this higher incidence. Further investigations are required to characterize the pathophysiologic mechanisms of VTE development following splenectomy. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

This report summarizes the risk communication activities of Nuclear Fuel Cycle Engineering Laboratories conducted by mainly Risk Communication Study Office. To gain trust and understanding of the local community for nuclear energy, a 'Risk Communication Study Team' was set up at former Tokai Works, Japan Nuclear Cycle Development Institute (JNC) in January, 2001. When former JNC and former Japan Atomic Energy Research Institute (JAERI) were merged in October, 2005, the Team was changed to 'Risk Communication Study Office' in Nuclear Fuel Cycle Engineering Laboratories. This report shows the risk communication activities implemented from January, 2001 to March 2007. The activities are classified into three categories: research and study on risk communication, message design and development of information transmission tools, and implementation of risk communication. As for the research and study, we investigated the risk communication about nuclear energy in Western countries. As for the message design, we made messages under our basic policy of showing information clearly that residents want to know. We have prepared about 300 messages in slide format (Microsoft Power Point) and compiled them in a report. More easy-to understand messages were created from the viewpoint of the residents by working in collaboration with local residents, not making messages by ourselves. As for the development of information transmission tools, we have been developing a portal website, 'Risk Information Navigator', which provides information about risks that exist in daily life such as traffic accidents and natural disasters, as well as risk information on nuclear technology. We produced videos and environmental panels as information transmission tools, and made poster panels, clear holder, Karuta' (Japanese card game), and so on in the collaboration work with residents. As a practice of risk communication, we have been carrying out Cycle Friendly Talk', which is direct dialogue within

Conclusions: Analyses revealed a relationship between the level of self-reported EF and risk taking behaviors in this group of sheltered homeless urban youths. Those with lower self-reported executive functioning had higher rates of engagement in multiple substance-related risk taking behaviors. These findings are important because they are a first step towards identifying contributions to risk-taking behavior in urban homeless youths. Identifying potential factors like low self-reported EF better allows us to potentially intervene, thereby providing focused support to youths who are at higher risk for engaging in problematic behaviors.

Do adolescents who are night owls have a higher risk of dental caries? - a case-control study.
Lundgren, A-M; Öhrn, K; Jönsson, B
2016-08-01
The aim was to evaluate the association between circadian rhythm and the risk of caries in adolescents, as well as their dietary and toothbrushing habits. A group of 196 adolescents (15 and 16 years old) were divided into two equal groups based on caries risk (case = high risk; and control = low risk). Before their dental examinations, they were asked to complete a questionnaire. The questionnaire included questions on circadian rhythm, dietary and oral self-care habits, and demographic variables. The participants were divided into three circadian types: evening types who are alert in the evening and tired in the morning; morning types who are the opposite; and neutral types who are neither particularly alert in the evening nor extremely tired in the morning. The most common sleep-cycle group type was neutral (50%). After this came evening types (37%) and finally morning types (13%). Morning and neutral types reported more frequently than evening types that they had breakfast every morning and brushed their teeth twice a day. More evening types were categorized as at high risk of caries. Circadian rhythm, breakfast habits and toothbrushing frequency were associated with a high risk of caries. The predicted probability of being at high risk of caries was almost four times higher for evening types than for morning types (OR 3.8; 95% CI 1.3-10.9). Adolescents who belonged to the evening circadian rhythm group brushed their teeth more seldom, ate breakfast less regularly and had a higher risk of caries than morning types. A patient's circadian rhythm should be considered when planning oral health education for adolescents with a high risk of caries. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Abstract Background Because of the belief that Nairobi is a low risk zone for malaria, little empirical data exists on malaria risk in the area. The aim of this study was to explore the risk of perceived malaria and some associated factors in Nairobi informal settlements using self-reported morbidity survey. Methods The survey was conducted from May to August 2004 on 7,288 individuals in two informal settlements of Nairobi. Participants were asked to report illnesses they experienced in the past 14 days. Logistic regression was used to estimate the odds of perceived-malaria. The model included variables such as site of residence, age, ethnicity and number of reported symptoms. Results Participants reported 165 illnesses among which malaria was the leading cause (28.1%. The risk of perceived-malaria was significantly higher in Viwandani compared to Korogocho (OR 1.61, 95%CI: 1.10–2.26. Participants in age group 25–39 years had significantly higher odds of perceived-malaria compared to those under-five years (OR 2.07, 95%CI: 1.43–2.98. The Kikuyu had reduced odds of perceived-malaria compared to other ethnic groups. Individuals with five and more symptoms had higher odds compared to those with no symptoms (OR 23.69, 95%CI: 12.98–43.23. Conclusion Malaria was the leading cause of illness as perceived by the residents in the two informal settlements. This was rational as the number of reported symptoms was highly associated with the risk of reporting the illness. These results highlight the need for a more comprehensive assessment of malaria epidemiology in Nairobi to be able to offer evidence-based guidance to policy on malaria in Kenya and particularly in Nairobi.

Atrophic gastritis of the corporal mucosa is a frequent cause of hypergastrinemia. Hypergastrinemia is implicated in colorectal cancer development. To assess whether hypergastrinemic atrophic gastritis is associated with a higher risk of neoplastic colorectal lesions. Among 441 hypergastrinemic atrophic gastritis patients, 160 who were aged >40 and underwent colonoscopy for anaemia, diarrhoea or colorectal cancer-screening were retrospectively selected. Each patient was age- and gender-matched with a normogastrinemic control with healthy stomach. Controls had colonoscopy, gastroscopy with biopsies and gastrin assessment. 160 hypergastrinemic atrophic gastritis patients and 160 controls were included. 28 atrophic gastritis patients and 36 controls had neoplastic colorectal lesions (p=0.33). Patients and controls did not differ for frequency of colorectal adenomas (10.6% vs. 13.1%, p=0.60) or cancer (6.9% vs. 9.4%, p=0.54). Hypergastrinemic atrophic gastritis was not associated with a higher probability of developing colorectal cancer (OR 1.03, 95% CI 0.34-3.16). Age >50 years (OR 3.86) but not hypergastrinemia (OR 0.61) was associated with colorectal cancer. Hypergastrinemic atrophic gastritis is not associated with higher risk for colorectal cancer. Atrophic gastritis-related hypergastrinemia is not associated with an increased risk of neoplastic colorectal lesions. Closer surveillance of colonic neoplasia in atrophic gastritis patients seems not appropriate. Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

Full Text Available Epidemiological studies may be subject to selective reporting, but empirical evidence thereof is limited. We empirically evaluated the extent of selection of significant results and large effect sizes in a large sample of recent articles.We evaluated 389 articles of epidemiological studies that reported, in their respective abstracts, at least one relative risk for a continuous risk factor in contrasts based on median, tertile, quartile, or quintile categorizations. We examined the proportion and correlates of reporting statistically significant and nonsignificant results in the abstract and whether the magnitude of the relative risks presented (coined to be consistently > or =1.00 differs depending on the type of contrast used for the risk factor. In 342 articles (87.9%, > or =1 statistically significant relative risk was reported in the abstract, while only 169 articles (43.4% reported > or =1 statistically nonsignificant relative risk in the abstract. Reporting of statistically significant results was more common with structured abstracts, and was less common in US-based studies and in cancer outcomes. Among 50 randomly selected articles in which the full text was examined, a median of nine (interquartile range 5-16 statistically significant and six (interquartile range 3-16 statistically nonsignificant relative risks were presented (p = 0.25. Paradoxically, the smallest presented relative risks were based on the contrasts of extreme quintiles; on average, the relative risk magnitude was 1.41-, 1.42-, and 1.36-fold larger in contrasts of extreme quartiles, extreme tertiles, and above-versus-below median values, respectively (p < 0.001.Published epidemiological investigations almost universally highlight significant associations between risk factors and outcomes. For continuous risk factors, investigators selectively present contrasts between more extreme groups, when relative risks are inherently lower.
Review of NASA's Evidence Reports on Human Health Risks. 2015 Letter Report

2016-01-01
NASA has requested a study from the Institute of Medicine (IOM) to provide an independent review of more than 30 evidence reports on human health risks for long duration and exploration spaceflight. The evidence reports, which are publicly available, are categorized into five broad categories: (1) behavioral health and performance; (2) human health countermeasures (with a focus on bone metabolism and orthopedics, nutrition, immunology, and cardiac and pulmonary physiology); (3) radiation; (4) human factors issues; and (5) exploration medical capabilities. The reports are revised on an ongoing basis to incorporate new scientific information. In conducting this study, an IOM ad hoc committee will build on the 2008 IOM report Review of NASA's Human Research Program Evidence Books. That report provided an assessment of the process used for developing the evidence reports and provided an initial review of the evidence reports that had been completed at that time. Each year, NASA staff will identify a set of evidence reports for committee review. Over the course of the study all evidence reports will be reviewed. The committee will hold an annual scientific workshop to receive input on the evidence reports it is reviewing that year and an update on the recent literature. The committee will issue an annual letter report that addresses the following questions relevant to each evidence report: 1. Does the evidence report provide sufficient evidence, as well as sufficient risk context, that the risk is of concern for long-term space missions? 2. Does the evidence report make the case for the research gaps presented? 3. Are there any additional gaps in knowledge or areas of fundamental research that should be considered to enhance the basic understanding of this specific risk? 4. Does the evidence report address relevant interactions among risks? 5. Is input from additional disciplines needed? 6. Is the breadth of the cited literature sufficient? 7. What is the overall

Several studies in The Netherlands revealed ethnic disparities in hypertension prevalence, but none have focused on the Moluccan-Dutch, a migrant group from Indonesia that settled in The Netherlands in 1951. The Moluccan-Dutch are considered to be fairly well integrated in Dutch society. The aim of this study was to compare hypertension prevalence among the Moluccan-Dutch to the native Dutch and to explore the contribution of known risk factors. A health interview survey was conducted from August 2012 till March 2013 among nineteen Moluccan neighborhoods, resulting in the inclusion of 708 participants. The primary outcome variable was self-reported prevalence of hypertension. Explanatory variables were BMI, exercise, smoking, alcohol intake and mental health status. Data on the control group was extracted from the Dutch National Health Survey 2011, using a similar questionnaire. Differences in risk factor exposure were explored using Chi-square tests and the contribution of risk factors, separately and combined, was explored using multivariate logistic regression analysis. Moluccan-Dutch showed higher odds for reporting hypertension when compared to native Dutch, after adjusting for age and level of education (OR = 1.38; 95% CI = 1.13-1.69) and additional risk factors (OR = 1.49; 95% CI = 1.19-1.88). A higher prevalence of hypertension was found in both Moluccan-Dutch men (26.4% vs. 16.7%; p Dutch men showed higher prevalence of hypertension. The Moluccan-Dutch may be at increased risk for reporting hypertension. These results suggest that long-term stay over several generations does not necessarily result in similar levels of hypertension prevalence as the host population.

In recent years, the need for effective risk management, internal control and transparent risk reporting has become an important corporate governance principle and a predominant issue in business. Already in 1987, the AICPA[ ] report stated that shareholders are increasingly demanding that financial statements include more information concerning the risks and uncertainties companies are facing (Schrand and Elliott, 1998). Abraham and Cox (2007) claim that this information can help investors t...

A combined estimate of injuries within a specific sport through pooled analysis provides more precise evidence and meaningful information about the sport, whilst controlling for between-study variation due to individual sub-cohort characteristics. The objective of this analysis was to review all published rugby league studies reporting injuries from match and training participation and report the pooled data estimates for rugby league concussion injury epidemiology. A systematic literature analysis of concussion in rugby league was performed on published studies from January 1990 to October 2015. Data were extracted and pooled from 25 studies that reported the number and incidence of concussions in rugby league match and training activities. Amateur rugby league players had the highest incidence of concussive injuries in match activities (19.1 per 1000 match hours) while semi-professional players had the highest incidence of concussive injuries in training activities (3.1 per 1000 training hours). This pooled analysis showed that, during match participation activities, amateur rugby league participants had a higher reported concussion injury rate than professional and semi-professional participants. Semi-professional participants had nearly a threefold greater concussion injury risk than amateur rugby league participants during match participation. They also had nearly a 600-fold greater concussion injury risk than professional rugby league participants during training participation.

The cumulative effect of the female athlete triad (Triad) risk factors on the likelihood of low bone mineral density (BMD) in exercising women is unclear. This study aimed to determine the risk of low BMD in exercising women with multiple Triad risk factors. We retrospectively examined cross-sectional data from 437 exercising women (mean ± SD age of 18.0 ± 3.5 yr, weighed 57.5 ± 7.1 kg with 24.5% ± 6.1% body fat) obtained at baseline from 4 prospective cohort studies examining Triad risk factors. Questionnaires were completed to obtain information on demographic characteristics, self-reported eating attitudes/behaviors, menstrual function, sport/activity participation, and medication use. Height and body weight were measured. BMD was measured using dual energy x-ray absorptiometry. Low BMD was defined as z-scores of exercising women. Further research should be conducted to develop a user-friendly algorithm integrating these indicators of risk for low BMD in exercising women (particularly factors associated with low BMI/body weight, menstrual dysfunction, lean sport/activity participation, and elevated dietary restraint).

Full Text Available The intangible nature of education is one contributor to consumers’ perception of risk prior to their purchase and consumption. This risk includes: functional risk, financial risk, temporal risk, physical risk, psychological risk and social risk. The presence of these risks often makes consumer evaluation prior to purchase and consumption difficult. Invoking a service guarantee is a platform available to enable higher educational institutions to minimize such risk perception so as to induce purchase. Specifically, service guarantee for higher education entails the application of teaching performance guarantee. This form of guarantee focuses on two important customer groups of higher educational institutions namely, students and faculty members, and focuses only on a specific performance aspect such as instructor’s performance. Thus, if students are dissatisfied with an instructor’s performance they are entitled to receive their money back. The imposition of such a teaching performance guarantee would implicate instructor’s accountability for certain aspects of their performance. It also establishes a mechanism to solicit feedback to better understand why and how instructors fail. Consequently, service performance guarantee creates a high level of customer focus and signals instructors’ care towards students

2014-01-01
Background Sensitive general cardiometabolic risk assessment tools of modifiable risk factors would be helpful and practical in a range of primary prevention interventions or for preventive health maintenance. Purpose To develop and validate a cumulative general cardiometabolic risk score that focuses on non–self-reported modifiable risk factors such as glycosylated hemoglobin (HbA1c) and BMI so as to be sensitive to small changes across a span of major modifiable risk factors, which may not individually cross clinical cut off points for risk categories. Methods We prospectively followed 2,359 cardiovascular disease (CVD)-free subjects from the Framingham offspring cohort over a 14–year follow-up. Baseline (fifth offspring examination cycle) included HbA1c and cholesterol measurements. Gender–specific Cox proportional hazards models were considered to evaluate the effects of non–self-reported modifiable risk factors (blood pressure, total cholesterol, high–density lipoprotein cholesterol, smoking, BMI, and HbA1c) on general CVD risk. We constructed 10–year general cardiometabolic risk score functions and evaluated its predictive performance in 2012–2013. Results HbA1c was significantly related to general CVD risk. The proposed cardiometabolic general CVD risk model showed good predictive performance as determined by cross-validated discrimination (male C-index=0.703, 95% CI=0.668, 0.734; female C-index=0.762, 95% CI=0.726, 0.801) and calibration (lack-of-fit χ2=9.05 [p=0.338] and 12.54 [p=0.128] for men and women, respectively). Conclusions This study presents a risk factor algorithm that provides a convenient and informative way to quantify cardiometabolic risk based on modifiable risk factors that can motivate an individual’s commitment to prevention and intervention.

News reporting on research studies may influence attitudes about health risk, support for public health policies, or attitudes towards people labeled as unhealthy or at risk for disease. Across five experiments (N = 2123) we examined how different news framings of obesity research influence these attitudes. We exposed participants to either a control condition, a news report on a study portraying obesity as a public health crisis, a news report on a study suggesting that obesity may not be as much of a problem as previously thought, or an article discussing weight-based discrimination. Compared to controls, exposure to the public health crisis article did not increase perception of obesity-related health risks but did significantly increase the expression of antifat prejudice in four out of seven comparisons. Across studies, compared to controls, participants who read an article about weight-based discrimination were less likely to agree that overweight constitutes a public health crisis or to support various obesity policies. Effects of exposure to an article questioning the health risks associated with overweight and obesity were mixed. These findings suggest that news reports on the "obesity epidemic" - and, by extension, on public health crises commonly blamed on personal behavior - may unintentionally activate prejudice.

This study was designed to evaluate the impact of educational status on global cardiovascular risk in a southern Italian urban population. The study population consisted of 488 consecutive outpatients aged 18 years and older. Educational status was categorized according to the number of years of formal education as follows: (1) low education group (education group (10-15 years). In both groups, cardiometabolic comorbidities (obesity, visceral obesity, diabetes, dyslipidemia, metabolic syndrome, microalbuminuria, left ventricular hypertrophy) and global cardiovascular risk, according to international guidelines, were analyzed. Left ventricular mass index and ejection fraction by echocardiography and E/A ratio, by pulsed-wave Doppler, were calculated. The low education group was characterized by a significantly higher prevalence of patients with visceral obesity (P=.021), hypertension (P=.010), metabolic syndrome (P=.000), and microalbuminuria (P=.000) and greater global cardiovascular risk (P=.000). Significantly increased levels of microalbuminuria (P=.000) and significantly decreased values of E/A ratio (P=.000) were also detected in the low education group. Global cardiovascular risk correlated directly with waist-to-hip ratio (P=.010), microalbuminuria (P=.015), and the metabolic syndrome (P>.012) and inversely with educational status (P=.000). Education was independently (P=.000) associated with global cardiovascular risk. These data indicate a strong association between low education and cardiometabolic comorbidities suitable to influence the evolution of chronic degenerative diseases. Preventive strategies need to be more efficient and more effective in this patient population. ©2015 Wiley Periodicals, Inc.

The standard for stroke risk stratification is the Framingham Stroke Risk Function (FSRF), an equation requiring an examination for blood pressure assessment, venipuncture for glucose assessment, and ECG to determine atrial fibrillation and heart disease. We assess a self-reported stroke risk function (SRSRF) to stratify stroke risk in comparison to the FSRF. Participants from the REGARDS study (Reasons for Geographic and Racial Differences in Stroke) were evaluated at baseline and followed for incident stroke. The FSRF was calculated using directly assessed stroke risk factors. The SRSRF was calculated from 13 self-reported questions to exclude those with prevalent stroke and assess stroke risk. Proportional hazards analysis was used to assess incident stroke risk using the FSRF and SRSRF. Over an average 8.2-year follow-up, 939 of 23 983 participants had a stroke. The FSRF and SRSRF produced highly correlated risk scores ( r Spearman =0.852; 95% confidence interval, 0.849-0.856); however, the SRSRF had higher discrimination of stroke risk than the FSRF (c SRSRF =0.7266; 95% confidence interval, 0.7076-0.7457; c FSRF =0.7075; 95% confidence interval, 0.6877-0.7273; P =0.0038). The 10-year stroke risk in the highest decile of predicted risk was 11.1% for the FSRF and 13.4% for the SRSRF. A simple self-reported questionnaire can be used to identify those at high risk for stroke better than the gold standard FSRF. This instrument can be used clinically to easily identify individuals at high risk for stroke and also scientifically to identify a subpopulation enriched for stroke risk. © 2017 American Heart Association, Inc.

Full Text Available Body weight is regulated by energy intake which occurs several times a day in humans. In this meta-analysis, we evaluated whether eating frequency (EF is associated with obesity risk and energy intake in adults without any dietary restriction. Experimental and observational studies published before July 2015 were selected through English-language literature searches in several databases. These studies reported the association between EF and obesity risk (odd ratios, ORs in adults who were not in dietary restriction. R software was used to perform statistical analyses. Ten cross-sectional studies, consisting of 65,742 participants, were included in this analysis. ORs were considered as effect size for the analysis about the effect of EF on obesity risk. Results showed that the increase of EF was associated with 0.83 time lower odds of obesity (i.e., OR = 0.83, 95% confidence intervals (CI 0.70–0.99, p = 0.040. Analysis about the effect of EF on differences in participants’ energy intake revealed that increased EF was associated with higher energy intake (β = 125.36, 95% CI 21.76–228.97, p = 0.017. We conclude that increased EF may lead to lower obesity risk but higher energy intake. Clinical trials are warranted to confirm these results and to assess the clinical practice applicability.

Pre-transplant fixed pulmonary hypertension is associated with higher post-transplant mortality. In this study, we assessed the significance of pre-transplant reversible pulmonary hypertension in patients undergoing cardiac transplantation. Overall, we studied 182 patients with baseline normal pulmonary pressures or reversible pulmonary hypertension, defined as a decrease in pulmonary vascular resistance (PVR) to 50 mm Hg had a higher risk of death (odds ratio [OR] 5.96, 95% confidence interval [CI] 1.46 to 19.84 as compared with PAS 4.0 WU, but patients with TPG > or =16 had a higher risk of mortality (OR 4.93, 95% CI 1.84 to 13.17). PAS pressure was an independent predictor of mortality (OR 1.04, 95% CI 1.02 to 1.06). Recipient body mass index, history of sternotomy; and donor ischemic time were the other independent predictors of mortality. Pre-transplant pulmonary hypertension, even when reversible to a PVR of < or =2.5 WU, is associated with a higher mortality post-transplant.

The intensity of biotic interactions varies around the world, in such a way that mortality risk imposed by natural enemies is usually higher in the tropics. A major role of offspring attendance is protection against natural enemies, so the benefits of this behaviour should be higher in tropical regions. We tested this macroecological prediction with a meta-regression of field experiments in which the mortality of guarded and unguarded broods was compared in arthropods. Mortality of unguarded broods was higher, and parental care was more beneficial, in warmer, less seasonal environments. Moreover, in these same environments, additional lines of defence further reduced offspring mortality, implying that offspring attendance alone is not enough to deter natural enemies in tropical regions. These results help to explain the high frequency of parental care among tropical species and how biotic interactions influence the occurrence of parental care over large geographic scales. Finally, our findings reveal that additional lines of defences - an oftentimes neglected component of parental care - have an important effect on the covariation between the benefits of parental care and the climate-mediated mortality risk imposed by natural enemies. © 2016 Cambridge Philosophical Society.
Risk Aversion and Public Reporting. Part 2: Mitigation Strategies.
Shahian, David M; Jacobs, Jeffrey P; Badhwar, Vinay; D'Agostino, Richard S; Bavaria, Joseph E; Prager, Richard L

Part 1 of this review summarizes the consequences of risk aversion and the observational studies and surveys relevant to this phenomenon, almost all of which are derived from cardiac surgery and interventional cardiology. In Part 2, we describe the root cause of risk aversion-the belief by providers that current risk adjustment is inadequate to account for the severity of their highest-risk patients, thereby prejudicing their publicly reported performance scores. Evidence supporting the robustness of current risk adjustment is presented, as well as nine potential strategies to further mitigate risk aversion: optimization of data source, risk models, and performance measures; exclusion of high-risk patients; exclusion of non-procedure-related end points; separate reporting of high-risk patients; reporting by condition or diagnosis rather than by procedures; reporting at the hospital or program level rather than the physician level; collaborative, cross-disciplinary decision making; active surveillance for risk aversion; and improved stakeholder education. Of these, the first is most desirable, widely applicable, and resistant to gaming. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

The objective of this analysis was to assess risk factors for self-reported osteoarthritis (OA) in an ethnically diverse cohort of women. The participants were postmenopausal women aged 50 to 79 (n=146,494) participating in the clinical trial and observational study of the Women’s Health Initiative (WHI). Baseline OA and risk factors were collected from WHI questionnaires. Logistic regression was used to find the association between the risk factors and OA. Risk factor distribution and ethnicity interaction terms were used to assess ethnic differences in OA risk. Forty-four percent of the participants reported OA. Older age (odds ratio (OR)70–79 vs 50–59=2.69, 95% confidence interval (CI)=2.60–2.78) and higher body mass index (BMI) (ORBMI≥40.0 vs <24.9=2.80, 95% CI=2.63–2.99) were found to be the strongest risk factors associated with self-reported OA. The prevalence of obesity (BMI≥30.0) was 57.9% in African Americans, 51.0% in American Indians, 41.9% in Hispanic whites, and 32.9% in non-Hispanic whites. The prevalence of other major OA risk factors was higher in African-American, American-Indian, and Hispanic white women than in non-Hispanic white women. Non-Hispanic white women who were in the extreme obese category (BMI≥40.0λkg/m2) had a 2.80 times (95% CI=2.63, 2.99) greater odds of self-reported OA. The odds were even higher in American-Indian (OR=4.22, 95% CI=1.82, 9.77) and African-American (OR=3.31, 95% CI=2.79, 3.91) women, indicating a significant interactive effect of BMI and ethnicity on odds of OA. In conclusion, OA is a highly prevalent condition in postmenopausal women, and there are differential effects according to ethnicity. PMID:18662212
Are female healthcare workers at higher risk of occupational injury?

Differential risks of occupational injuries by gender have been examined across various industries. With the number of employees in healthcare rising and an overwhelming proportion of this workforce being female, it is important to address this issue in this growing sector. To determine whether compensated work-related injuries among females are higher than their male colleagues in the British Columbia healthcare sector. Incidents of occupational injury resulting in compensated days lost from work over a 1-year period for all healthcare workers were extracted from a standardized operational database and the numbers of productive hours were obtained from payroll data. Injuries were grouped into all injuries and musculoskeletal injuries (MSIs). Detailed analysis was conducted using Poisson regression modelling. A total of 42 332 employees were included in the study of whom 11% were male and 89% female. When adjusted for age, occupation, sub-sector, employment category, health region and facility, female workers had significantly higher risk of all injuries [rate ratio (95% CI) = 1.58 (1.24-2.01)] and MSIs [1.43 (1.11-1.85)] compared to their male colleagues. Occupational health and safety initiatives should be gender sensitive and developed accordingly.

Depression has been reported to increase the risk of subsequently developing dementia, but the nature of this relation remains to be elucidated. Depression can be a prodrome/manifestation of dementia or an early risk factor, and the effect may differ according to depression subtypes. Our aim was to study the association between early-onset depression and different depression subtypes, and the later occurrence of dementia. We conducted a cohort study including 322 subjects with depression, recruited between 1977 and 1984. A comparison cohort (non-exposed) was recruited retrospectively, to include 322 subjects admitted at the same hospital for routine surgery (appendicectomy or cholecystectomy), at the same period as the depressed cohort. Subjects were contacted again between 2009 and 2014, to assess their dementia status. We computed the risk for dementia in subjects with early onset depression and quantified the association between different depression subtypes (namely melancholic, anxious, and psychotic) and dementia. The odds of dementia were increased by 2.90 times (95% C.I. 1.61-5.21; pdepressed cohort when compared to the surgical cohort. When the analysis was restricted to patients younger than 45 years old at baseline, the odds for dementia in the depressed cohort were also significantly higher when compared to the surgical cohort (8.53; 95% C.I. 2.40-30.16). In the multivariate Cox analysis, subjects having depression with melancholic features had an increased risk for developing dementia compared to those without melancholic features (HR=3.64; 95% C.I. 1.78-11.26; p=0.025). About 59% of the participants with depression and 53% of those non-exposed were lost during follow up. The inclusion of biological biomarkers would strengthen the results. The sample included a low number of bipolar patients. These results support depression as an early risk factor for dementia. Depression with melancholic features was found as an important risk factor for dementia

Background and purpose: To ascertain the rate, type, significance, trends and the potential risk factors associated with radiotherapy incidents in a large academic department. Materials and methods: Data for all radiotherapy activities from July 2001 to January 2011 were reviewed from radiotherapy incident reporting forms. Patient and treatment data were obtained from the radiotherapy record and verification database (MOSAIQ) and the patient database (HOSPRO). Logistic regression analyses were performed to determine variables associated with radiotherapy incidents. Results: In that time, 65,376 courses of radiotherapy were delivered with a reported incident rate of 2.64 per 100 courses. The rate of incidents per course increased (1.96 per 100 courses to 3.52 per 100 courses, p < 0.001) whereas the proportion of reported incidents resulting in >5% deviation in dose (10.50 to 2.75%, p < 0.001) had decreased after the introduction of an online electronic reporting system. The following variables were associated with an increased rate of incidents: afternoon treatment time, paediatric patients, males, inpatients, palliative plans, head-and-neck, skin, sarcoma and haematological malignancies. In general, complex plans were associated with higher incidence rates. Conclusion: Radiotherapy incidents were infrequent and most did not result in significant dose deviation. A number of risk factors were identified and these could be used to highlight high-risk cases in the future. Introduction of an online electronic reporting system resulted in a significant increase in the number of incidents being reported
Why do perfectionists have a higher burnout risk than others? The mediational effect of workaholism
van Beek, Ilona; Schaufeli, Wilmar B.; Taris, Toon W.
2010-01-01
Previous research has revealed that perfectionists have a higher burnout risk than others, but the mechanisms accounting for this association have rarely been examined. The present study proposes that workaholism mediates this relation, as previous research revealed that (a) perfectionists are more likely to be workaholics than others, and (b) workaholics have a higher burnout risk than others. Using cross-sectional data from 199 Dutch managers, regression analyses revealed that holding high ...

Discussion: Higher pretransplantation HbA1c above 5.4% is independently associated with greater risk of PTDM among kidney transplant recipients. A continuous relationship between pretransplantation HbA1c and risk of PTDM suggests that increased risk starts at HbA1c levels well below current thresholds for prediabetes.

Full Text Available Recent policy changes in sustainability reporting, such as the ones related to the new European Directive on non-financial disclosure (2014/95/EU, the standards issued by the American Sustainability Accounting Standard Board (SASB, the G4 guidelines issued by the Global Sustainability Standard Board (GSSB, and the framework of the International Integrated Reporting Council (IIRC stress the importance of extending the disclosure of ethical, social, and environmental risks within financial and social-environmental reporting. Institutional pressure has notably increased among organizations, in setting up risk management tools to understand sustainability risks within managerial and reporting practices. Given such institutional pressure, the corporate reaction in providing additional sustainability risk disclosure calls for attention and scrutiny. Therefore, this study aims at addressing such issues from an exploratory perspective. We based our analysis on a sample of large Italian organizations that issued sustainability disclosure in accordance with the Global Reporting Initiative (GRI, G4 guidelines, and we tested the relationship between their level of risk disclosure and other relevant variables. Consistently with the literature, we found that “experienced” sustainable reporters provide a significant volume of disclosure, and that disclosure quality on risk is positively influenced by their international presence and reporting experience. However, when accounting for specific risk-related areas of disclosure, only a few of them seem to adopt a managerial perspective linking strategy, risk metrics, and disclosure.

Recently, risk reporting has gained interest in financial reporting practice, regulation, and international research. Social and environmental reporting is seen to benefit shareholders more by reducing risk than by increasing return. The researchers showed that the annual report is the most favoured channel of disclosure, along with presentation to investors. The general message is that, as far as annual reports go, quantified, verifiable disclosures have the most credibility and relevance. O...

We aimed to measure cancer knowledge and feasibility of a screening colonoscopy among a cohort of individuals at higher risk of colon cancer. This study was conducted as part of an ongoing screening cohort, in which first degree relatives (FDRs) of patients with colon cancer are invited to participate in a free of charge screening colonoscopy. We enrolled 1017 FDRs in the study between 2013 and 2014 measuring their data on demographics, cancer knowledge and colonoscopy uptake. A p value of aware of their increased risk for cancer, near 35.0% had ever heard about colonoscopy with 22% aware of the correct age to start screening. Comparing cancer knowledge of FDRs at high risk versus those at moderate risk, we recorded non-significant differences (p>0.05). Almost two-thirds of FDRs expressed willingness to undergo a colonoscopy and 49.2% completed the procedure, of which 12.8% had advanced neoplasm. Our data indicated that remarkable numbers of FDRs were not still informed of their cancer risk or never received a physician recommendation for screening. The desirable uptake at first invitation, which would be higher over successive invitations, supports the feasibility of a family-based recruitment approach for early screening. This has promising implications to introduce targeted screening colonoscopy into the healthcare system in Iran and other developing nations. Published by the BMJ Publishing Group Limited.

Full Text Available Introduction: A 2009 National Academies of Sciences report on child mental health prevention and treatment concluded that screening for mental health risk is an essential component of service delivery. To date, however, there are few practical assessments available or practices in place that measure individual child risk, or risk aggregated at the school or community level. This study examined the utility of a 30-item paper and pencil student self-report screener of behavioral and emotional risk (BER for surveying community risk among 7 schools. Methods: In 2010, 2,222 students in 3 middle and 4 high schools in a medium-sized school district in Georgia were administered the Behavioral and Emotional Screening System Self-Report Child/Adolescent form (BESS Student. The BESS is designed to measure 4 sub-syndromal BER factors for developing mental health disorders: inattention/hyperactivity, internalizing, school problems, and personal adjustment. Analysis of Variance and Chi Square analyses were used to assess the association between adolescent self-reported BER as an indicator of school BER, grade level, child ethnic identification and gender, socioeconomic status, and special education placement status.Results: BESS scores differentiated well between schools for overall BER and special education status, as well as between grade levels, ethnicity, and gender groups. One high school, known by the school administration to have numerous incidents of student behavior problems, had the most deviant 4 BER domain scores of all 7 schools. Girls rated themselves as having a higher prevalence of BER (14% than boys (12%; middle school students reported fewer difficulties than high school students.Conclusion: Middle and high school students were capable of identifying significant differences in their own BER across schools, suggesting that universal mental health risk screening viastudent self-report is potentially useful for identifying aggregated community

Half of the recovered expanded criteria donor (ECD) kidneys are discarded in the United States. A new kidney allocation system offers kidneys at higher risk of discard, Kidney Donor Profile Index (KDPI) >85%, to a wider geographic area to promote broader sharing and expedite utilization. Dual kidney transplantation (DKT) based on the KDPI is a potential option to streamline allocation of kidneys which otherwise would have been discarded. To assess the clinical utility of the KDPI in kidneys at higher risk of discard, we analyzed the OPTN/UNOS Registry that included the deceased donor kidneys recovered between 2002 and 2012. The primary outcomes were allograft survival, patient survival and discard rate based on different KDPI categories (90%). Kidneys with KDPI >90% were associated with increased odds of discard (OR = 1.99, 95% CI 1.74–2.29) compared to ones with KDPI 90% were associated with lower overall allograft failure (HR = 0.74, 95% CI 0.62–0.89) and better patient survival (HR = 0.79, 95% CI 0.64–0.98) compared to single ECD kidneys with KDPI >90%. Kidneys at higher risk of discard may be offered in the up-front allocation system as a DKT. Further modeling and simulation studies are required to determine a reasonable KDPI cutoff percentile.

Full Text Available The high prevalence of diabetes in Iran and other developing countries is chiefly attributed to urbanization. The objectives of the present study were to assess the prevalence of self-reported diabetes and to determine its associated risk factors. This study is a part of the national noncommunicable disease risk factor surveillance, conducted in 31 provinces of Iran in 2011. First, 10069 individuals, between 20 and 70 years old (3036 individuals from rural and 7033 from urban areas, were recruited. The major risk factors were studied using a modified WHO STEPS approach. Diabetes was considered based on self-reported diabetes. The prevalence of self-reported diabetes was 10% overall. The prevalence in the rural and urban settings was 7.4% and 11.1%, respectively. Moderate physical activity (OR=0.45, 95% CI=0.29–0.71 and family history of diabetesOR=6.53, 95% CI=4.29–9.93 were the most important risk factors among the rural residents and systolic blood pressure (OR=1.01, 95% CI=1–1.02, waist circumference (OR=1.02, 95% CI=1.01–1.03, and overweight (OR=1.36, 95% CI= 1–1.84 were significantly associated with self-reported diabetes in the urban residents. The prevalence of self-reported diabetes in the urban setting was higher than that in the rural setting. Physical inactivity, abdominal obesity, and high blood pressure were the most important risk factors associated with self-reported diabetes in Iran.

Some previous studies reported no significant association of consuming fruit or vegetables, or fruit and vegetables combined, with type 2 diabetes. Others reported that only a greater intake of green leafy vegetables reduced the risk of type 2 diabetes. To further investigate the relationship between them, we carried out a meta-analysis to estimate the independent effects of the intake of fruit, vegetables and fiber on the risk of type 2 diabetes. Searches of MEDLINE and EMBASE for reports of prospective cohort studies published from 1 January 1966 to 21 July 2014 were carried out, checking reference lists, hand-searching journals and contacting experts. The primary analysis included a total of 23 (11 + 12) articles. The pooled maximum-adjusted relative risk of type 2 diabetes for the highest intake vs the lowest intake were 0.91 (95% confidence interval [CI] 0.87-0.96) for total fruits, 0.75 (95% CI 0.66-0.84) for blueberries, 0.87 (95% CI 0.81-0.93) for green leafy vegetables, 0.72 (95% CI 0.57-0.90) for yellow vegetables, 0.82 (95% CI 0.67-0.99) for cruciferous vegetables and 0.93 (95% CI 0.88-0.99) for fruit fiber in these high-quality studies in which scores were seven or greater, and 0.87 (95% CI 0.80-0.94) for vegetable fiber in studies with a follow-up period of 10 years or more. A higher intake of fruit, especially berries, and green leafy vegetables, yellow vegetables, cruciferous vegetables or their fiber is associated with a lower risk of type 2 diabetes.

Some studies show an association between asthma and obesity, but it is unknown whether exposure to mold will increase the risk of asthma attacks among obese people. This study examined whether obese adults have a higher risk of asthma attacks than non-obese adults when exposed to indoor mold. We used data from the 2005 Behavioral Risk Factor Surveillance System to conduct a cross-sectional analysis among 9,668 respondents who reported exposure to indoor mold. With exposure to indoor mold, weighted prevalence of asthma attacks among obese respondents was 11.4% (95% confidence interval [CI] 6.0, 20.6], which was 2.3 times as high as among the exposed non-obese respondents (5.0%, 95% CI 2.8, 8.8). This ratio was almost the same as the ratio of 2.0:1 between the obese respondents (5.7%, 95% CI 4.6, 7.2) and the non-obese respondents (2.8%, 95% CI 2.3, 3.9) when neither group had exposure to mold. The odds ratio of asthma attack among obese people was 3.10 (95% CI 1.10, 8.67) for those with exposure to mold and 2.21 (95% CI 1.54, 3.17) for those without exposure to mold after adjusting for age, sex, race/ethnicity, and smoking status. Our study suggests that obese adults who have been exposed to indoor mold may not necessarily have a higher risk of asthma attack than obese adults who have not been exposed, even though obesity and exposure to indoor mold are both major risk factors for asthma attack. Medical professionals should not only incorporate weight-control or weight-reduction measures as the components of asthma treatment plans, but also advise asthma patients to avoid exposure to indoor mold.

Zonulin is considered a biomarker of increased intestinal permeability, and elevated levels have been found in celiac disease. The primary aim of this study was to examine the association between serum zonulin levels and gastrointestinal (GI) symptoms, and secondarily, between zonulin levels and anthropometric and metabolic factors. The offspring ( n = 363) of the participants of the Malmö Diet and Cancer cardiovascular cohort (MDC-CV) were invited to an anthropometric and clinical examination, where fasting plasma glucose levels were measured. Questionnaires about lifestyle factors and medical history were completed along with the Visual Analog Scale for Irritable Bowel Syndrome (VAS-IBS). Zonulin levels were measured in serum by ELISA. Neither GI symptoms nor GI diseases had any influence on zonulin levels. Higher zonulin levels were associated with higher waist circumference ( p = 0.003), diastolic blood pressure ( p = 0.003), and glucose levels ( p = 0.036). Higher zonulin levels were associated with increased risk of overweight ( p zonulin levels among individuals reporting GI symptoms or GI diseases, but higher zonulin levels are associated with higher waist circumference, diastolic blood pressure, fasting glucose, and increased risk of metabolic diseases.

N = 1,316 Grade 7 and 8 girls and boys (M age = 13.21 years) across three Australian states were randomly allocated to: Media Smart; Life Smart; Helping, Encouraging, Listening and Protecting Peers Initiative (HELPP) or control (usual school class). Moderation was explored by testing interaction effects for group (Media Smart; Life Smart; HELPP; Control) × moderator (SWC: higher-SWC; lower-SWC) × time (post-program; 6-month follow-up; 12-month follow-up), with baseline risk factor scores entered as covariates. Moderation effects were found for shape concern, weight concern, eating concern, regular eating (i.e., meal skipping), physical activity, body dissatisfaction, dieting, and perfectionism. Post-hoc testing found eating concern at post-program was the only variable where higher-SWC Media Smart participants experienced a reduction in risk relative to controls. Both higher-SWC Life Smart and HELPP participants reported an increase in eating concern relative to controls and both groups were skipping more meals than controls at 12-month follow-up. Amongst lower-SWC participants, Media Smart was the only group to experience a benefit relative to controls (physical activity). This study highlights the need for moderator analyses to become more routinely conducted in universal trials, to ensure that participants across baseline risk levels are benefiting and not harmed from program participation. © 2016 Wiley Periodicals, Inc.

Full Text Available Background: There is limited evidence about the prevalence and risk factors for non-communicable diseases (NCDs among older Ugandans. Therefore, this article is aimed at investigating the prevalence of self-reported NCDs and their associated risk factors using a nationally representative sample. Design: We conducted a secondary analysis of the 2010 Uganda National Household Survey (UNHS using a weighted sample of 2,382 older people. Frequency distributions for descriptive statistics and Pearson chi-square tests to identify the association between self-reported NCDs and selected explanatory variables were done. Finally, multivariable complementary log–log regressions to estimate the risk factors for self-reported NCDs among older people in Uganda were done. Results: About 2 in 10 (23% older persons reported at least one NCD [including hypertension (16%, diabetes (3%, and heart disease (9%]. Among all older people, reporting NCDs was higher among those aged 60–69 and 70–79; Muslims; and Pentecostals and Seventh Day Adventists (SDAs. In addition, the likelihood of reporting NCDs was higher among older persons who depended on remittances and earned wages; owned a bicycle; were sick in the last 30 days; were disabled; and were women. Conversely, the odds of reporting NCDs were lower for those who were relatives of household heads and were poor. Conclusions: In Uganda, self-reported NCDs were associated with advanced age, being a woman, having a disability, ill health in the past 30 days, being rich, depended on remittances and earning wages, being Muslim, Pentecostal and SDAs, and household headship. The Ministry of Health should prevent and manage NCDs by creating awareness in the public and improving the supply of essential drugs for these health conditions. Finally, there is a need for specialised surveillance studies of older people to monitor the trends and patterns of NCDs over time.

Full Text Available Abstract Background The identification of poor medicinal adherence is difficult because direct observation of medication use is usually impractical. Up to 50% of individuals on chronic therapies may not be taking their medication as prescribed. This study is one of the first to explore possible risk factors for over-reporting of antihypertensive adherence using electronic medication monitoring. Methods The adherence of 286 individuals on single-drug antihypertensive therapy in a large managed care organization was electronically monitored for approximately three months. Questionnaires on socioeconomic background, adherence to therapy, health beliefs, and social support before and after adherence monitoring were completed. Over-reporting of antihypertensive adherence was assessed by comparing the self-reported frequency of noncompliance with that determined from electronic dosing records. Risk factors for over-reporting were identified by contingency table analysis and step-wise logistic regression. Results Although only 21% of participants acknowledged missing doses on one or more days per week, electronic monitoring documented nonadherence at this or a higher level in 42% of participants. The following variables were associated with over-reporting: >1 versus 1 daily dose (OR = 2.58; 95% CI = 1.50–4.41; p = .0006, lower perceived health risk from nonadherence (OR = 1.35; 95% CI = 1.10–1.64; p = .0035, and annual household income of $30,000 (OR = 2.64; 95% CI = 1.13–6.18; p = .025. Conclusions Over-reporting of adherence may be affected by factors related to dosing frequency, health beliefs and socioeconomic status. This topic deserves further investigation in other patient populations to elucidate possible underlying behavioral explanations.

Federal Guidance Report No. 13 (FGR 13) provides risk coefficients for estimation of the risk of cancer due to low-level exposure to each of more than 800 radionuclides. Uncertainties in risk coefficients were quantified in FGR 13 for 33 cases (exposure to each of 11 radionuclides by each of three exposure pathways) on the basis of sensitivity analyses in which various combinations of plausible biokinetic, dosimetric, and radiation risk models were used to generate alternative risk coefficients. The present report updates the uncertainty analysis in FGR 13 for the cases of inhalation and ingestion of radionuclides and expands the analysis to all radionuclides addressed in that report. The analysis indicates that most risk coefficients for inhalation or ingestion of radionuclides are determined within a factor of 5 or less by current information. That is, application of alternate plausible biokinetic and dosimetric models and radiation risk models (based on the linear, no-threshold hypothesis with an adjustment for the dose and dose rate effectiveness factor) is unlikely to change these coefficients by more than a factor of 5. In this analysis the assessed uncertainty in the radiation risk model was found to be the main determinant of the uncertainty category for most risk coefficients, but conclusions concerning the relative contributions of risk and dose models to the total uncertainty in a risk coefficient may depend strongly on the method of assessing uncertainties in the risk model.

The objective of this analysis was to assess risk factors for self-reported osteoarthritis (OA) in an ethnically diverse cohort of women. The participants were postmenopausal women aged 50 to 79 (n=146,494) participating in the clinical trial and observational study of the Women's Health Initiative (WHI). Baseline OA and risk factors were collected from WHI questionnaires. Logistic regression was used to find the association between the risk factors and OA. Risk factor distribution and ethnicity interaction terms were used to assess ethnic differences in OA risk. Forty-four percent of the participants reported OA. Older age (odds ratio (OR)(70-79 vs 50-59)=2.69, 95% confidence interval (CI)=2.60-2.78) and higher body mass index (BMI) (OR(BMI>or=40.0 vs or=30.0) was 57.9% in African Americans, 51.0% in American Indians, 41.9% in Hispanic whites, and 32.9% in non-Hispanic whites. The prevalence of other major OA risk factors was higher in African-American, American-Indian, and Hispanic white women than in non-Hispanic white women. Non-Hispanic white women who were in the extreme obese category (BMI>or=40.0 kg/m(2)) had a 2.80 times (95% CI=2.63, 2.99) greater odds of self-reported OA. The odds were even higher in American-Indian (OR=4.22, 95% CI=1.82, 9.77) and African-American (OR=3.31, 95% CI=2.79, 3.91) women, indicating a significant interactive effect of BMI and ethnicity on odds of OA. In conclusion, OA is a highly prevalent condition in postmenopausal women, and there are differential effects according to ethnicity.

CONTEXT: Most societies believe that a mother's psychological state can influence her unborn baby. Severe adverse life events during pregnancy have been consistently associated with an elevated risk of low birth weight and prematurity. Such events during the first trimester have also been...... associated with risk of congenital malformations. OBJECTIVE: To assess the effect in offspring of antenatal maternal exposure to an objective measure of stress on risk of adverse neurodevelopment, specifically schizophrenia. We hypothesized that the strongest relationship would be to maternal exposures...... not linked with a higher risk of schizophrenia. CONCLUSIONS: Our population-based study suggests that severe stress to a mother during the first trimester may alter the risk of schizophrenia in offspring. This finding is consistent with ecological evidence from whole populations exposed to severe stressors...

Full Text Available Zonulin is considered a biomarker of increased intestinal permeability, and elevated levels have been found in celiac disease. The primary aim of this study was to examine the association between serum zonulin levels and gastrointestinal (GI symptoms, and secondarily, between zonulin levels and anthropometric and metabolic factors. The offspring (n = 363 of the participants of the Malmö Diet and Cancer cardiovascular cohort (MDC-CV were invited to an anthropometric and clinical examination, where fasting plasma glucose levels were measured. Questionnaires about lifestyle factors and medical history were completed along with the Visual Analog Scale for Irritable Bowel Syndrome (VAS-IBS. Zonulin levels were measured in serum by ELISA. Neither GI symptoms nor GI diseases had any influence on zonulin levels. Higher zonulin levels were associated with higher waist circumference (p = 0.003, diastolic blood pressure (p = 0.003, and glucose levels (p = 0.036. Higher zonulin levels were associated with increased risk of overweight (p < 0.001, obesity (p = 0.047, and hyperlipidemia (p = 0.048. We cannot detect altered zonulin levels among individuals reporting GI symptoms or GI diseases, but higher zonulin levels are associated with higher waist circumference, diastolic blood pressure, fasting glucose, and increased risk of metabolic diseases.

Dengue is a major mosquito-borne viral disease and an important public health problem. Identifying which factors are important determinants in the risk of dengue infection is critical in supporting and guiding preventive measures. In South-East Asia, half of all reported fatal infections are recorded in Indonesia, yet little is known about the epidemiology of dengue in this country. Hospital-reported dengue cases in Banyumas regency, Central Java were examined to build Bayesian spatial and spatio-temporal models assessing the influence of climatic, demographic and socio-economic factors on the risk of dengue infection. A socio-economic factor linking employment type and economic status was the most influential on the risk of dengue infection in the Regency. Other factors such as access to healthcare facilities and night-time temperature were also found to be associated with higher risk of reported dengue infection but had limited explanatory power. Our data suggest that dengue infections are triggered by indoor transmission events linked to socio-economic factors (employment type, economic status). Preventive measures in this area should therefore target also specific environments such as schools and work areas to attempt and reduce dengue burden in this community. Although our analysis did not account for factors such as variations in immunity which need further investigation, this study can advise preventive measures in areas with similar patterns of reported dengue cases and environment.

This study aimed to examine the relationships among self-reported oral health, oral hygiene practices, and oral human papillomavirus (HPV) infection in women at risk for sexually transmitted infections (STIs) in Ho Chi Minh City, Vietnam. Convenience and referral sampling methods were used in a clinic-based setting to recruit 126 women aged 18-45 years between August and October 2013. Behavioral factors were self-reported. Oral-rinse samples were tested for HPV DNA of 2 low-risk and 13 high-risk genotypes. A higher unadjusted prevalence of oral HPV infection was associated with poorer self-rated overall oral health (P = .001), reported oral lesions or problems in the past year (P = .001), and reported a tooth loss not because of injury (P = .001). Higher unadjusted prevalence of oral HPV infection was also associated with two measures of oral hygiene: lower frequencies of toothbrushing per day (P = .047) and gargling without toothbrushing (P = .037). After adjusting for other factors in multivariable logistic regression models, poorer self-rated overall oral health remained statistically associated with oral HPV infection (P = .042); yet the frequency of tooth-brushing per day did not (P = .704). Results corroborate the association between self-reported poor oral health and oral HPV infection. The effect of oral hygiene on oral HPV infection remains inconclusive.

To analyse the associations between demographic, socio-economic and lifestyle factors, and the risk of self-reported chlamydial infection among young adults (20-29 years old) in Stockholm, Sweden. This study was based on the Stockholm Public Health Survey of 2006 (N = 4278). Demographic factors (gender, age, and country of birth), socio-economic factors (individual and parental educational levels, individual income level, and employment status), and lifestyle factors (body mass index, mental health, alcohol consumption, and partnership status) were taken into account. Possible associations were analysed by logistic regression. The risk of self-reported chlamydial infection decreases with age, is higher among individuals both who personally, and whose parents, were educated to high school level compared to university level education, and is higher among those employed, unemployed or on sick-leave/pre-retired compared to students. The risk of chlamydial infection is also higher among subjects who report greater alcohol consumption, and those who live without a partner. After considering demographic, socio-economic and lifestyle factors, the associations with age, educational level, employment status and alcohol consumption are strong and statistically significant. Indicators of risk-taking behaviours, especially in settings with generally little educational ambition or options, should be incorporated in the design of STI prevention strategies.

Bilirubin concentrations have been recently reported to be negatively associated with type 2 diabetes mellitus. We examined the association between bilirubin concentrations and gestational diabetes mellitus. In a prospective cohort study, 2969 pregnant women were recruited prior to 16 weeks of gestation and were followed up until delivery. The value of bilirubin was tested and oral glucose tolerance test was conducted to screen gestational diabetes mellitus. The relationship between serum bilirubin concentration and gestational weeks was studied by two-piecewise linear regression. A subsample of 1135 participants with serum bilirubin test during 16-18 weeks gestation was conducted to research the association between serum bilirubin levels and risk of gestational diabetes mellitus by logistic regression. Gestational diabetes mellitus developed in 8.5 % of the participants (223 of 2969). Two-piecewise linear regression analyses demonstrated that the levels of bilirubin decreased with gestational week up to the turning point 23 and after that point, levels of bilirubin were increased slightly. In multiple logistic regression analysis, the relative risk of developing gestational diabetes mellitus was lower in the highest tertile of direct bilirubin than that in the lowest tertile (RR 0.60; 95 % CI, 0.35-0.89). The results suggested that women with higher serum direct bilirubin levels during the second trimester of pregnancy have lower risk for development of gestational diabetes mellitus.

The Normal Hematocrit Trial (NHT) was the largest trial of epoetin randomizing 1265 hemodialysis patients with cardiac disease to lower (9-11 g/dl) or higher (13-15 g/dl) hemoglobin (Hgb), hypothesizing that higher Hgb would reduce mortality, and improve survival and quality of life. The trial was terminated early, and a 1998 publication reported that targeting higher hematocrit levels led to an insignificant increase in the primary end points (death or myocardial infarct), or risk ratio 1.3, 95% confidence interval (CI), 0.9-1.90, but the P-value was not given, and all-cause death risk was not reported. A higher target reportedly did not increase hospitalization rates, but did significantly improve the 'physical function' domain of quality of life. Comparing the 1996 Food and Drug Administration (FDA)-filed clinical trial report to the 1998 publication, however, found several discrepancies. Among these, the 1998 article reported interim trial results with only the adjusted CI but did not state that the unadjusted CIs were 99.912th percentile, and despite being a secondary end point, reported only the association of achieved Hgb with higher quality of life score. Randomization to the higher target had actually increased the risk for the primary end point (risk ratio 1.28, 95% CI=1.06-1.56; P=0.0112; 99.92% CI=0.92-1.78), the risk of death (risk ratio 1.27, 95% CI=1.04-1.54), non-access thrombotic events (P=0.041), and hospitalization rate (P=0.04), while 'physical function' did not improve (P=0.88). Hence, disclosure of these results in the 1998 publication or access to the FDA-filed report on the NHT in the late 1990s would likely have led to earlier concerns about epoetin safety and greater doubts about its benefits.

Falling and fractures are a public health problem in elderly people. The aim of our study was to investigate whether nutritional status is associated with the risk of falling or fracture in community-dwelling elderly. Poor nutritional status was significantly associated with a higher risk of both falling and fractures. Nutrition could play a role to prevent falls and fractures. The purpose of this study is to investigate whether a poor nutritional status is associated with the risk of falling and of fracture in community dwelling elderly. Baseline nutritional status of participants was assessed using the Mini Nutritional Assessment (MNA). After a follow-up of 12 years, 6040 individuals with available data for falls and 6839 for fracture were included. People who presented the outcomes at baseline were excluded. Cox models were used to evaluate the associations between nutritional status and the risks of fall or fracture. The frequency of poor nutritional status (MNA ≤ 23.5), at baseline, was respectively 12.0% in the "fall study sample" and 12.8% in the "fracture study sample." Incident fall and fracture over 12 years were reported in 55.8 and 18.5% of the respective samples, respectively. In multivariate models controlled for sociodemographic data and several baseline health indicators, poor nutritional status was significantly associated with a higher risk of falling (hazard ratio (HR) = 1.66, 95% confidence interval (95% CI) 1.35-2.04 in men and HR = 1.20, 95% CI 1.07-1.34 in women) and with a higher risk of fracture (HR = 1.28, 95% CI 1.09-1.49). Poor nutritional status was associated with a higher risk of both falling and fractures in French elderly community-dwellers. Early screening and management of the nutritional status may be useful to reduce the frequency of these events in older people.
National report of France. Risks and risk assessment according to the law of France

This report encompasses the following chapters: the fundamentals of the law governing conventional industrial facilities, normative principles of atomic energy law; risk assessments in the law concerning conventional industrial facilities, risk assessment in the law concerning nuclear power plants; application of probabilistic methods in the field of nuclear safety, probabilistic methods in the safety assessment of modern aircraft; concept of risk in police regulations, 'Theorie des risques anormaux de voisinage' in public law on indemnification, causality and probability in civil law. It is stated in this report that in France, too, the idea of completely reforming the procedures of safety analysis is gaining ground, and the change from hitherto applied deterministic methods to logical risk analyses and probabilistic licensing is to be expected in the long run. This change will most probably be effected by defining a general risk acceptance criterion by means of conventions and, on the basis of this generally accepted criterion, proceed to defining an accepted, quantitatively determined risk standard both for a complete plant and for individual systems.

Full Text Available The pathophysiology of the placental malaria is not fully understood. If there is a fetal sex-specific susceptibility to malaria infection, this might add to the previous knowledge on the immunology, endocrinology and pathophysiology of placental malaria infections.This study was conducted to assess whether the sex of the fetus was associated with placental malaria infections.A cross-sectional study was performed including a secondary analysis of a cohort of women who were investigated for prevalence and risk factors (including fetal sex for placental malaria in eastern Sudan. Placental histology was used to diagnose placental malaria infections.Among 339 women enrolled, the mean (SD age was 25.8 (6.7 years and parity was 2.7 (2.2. Among the new born babies, 157 (46.3% were male and 182 (53.7% were female. Five (1.5%, 9 (2.7% and 103 (30.4% of the 339 placentas had active, active-chronic, past-chronic malaria infection on histopathology examination respectively, while 222 (65.5% of them showed no malaria infection. Logistic regression analyses showed no associations between maternal age or parity and placental malaria infections. Women who have blood group O (OR = 1.95, 95% CI = 1.19-3.10; P = 0.007 and women who had female new born were at higher risk for placental malaria infections (OR = 2.55, 95% CI = 1.57-4.13; P< 0.001.Fetal gender may be a novel risk factor for placental malaria. In this work the female placentas were at higher risk for malaria infections than the male placentas.

The APRI-project started in 1992 with participation of the Swedish Nuclear Power Inspectorate (SKI) and the Swedish utilities. The Finnish utility TVO joined the project in 1993. The aim of the project has been to work with phenomenological questions in severe accidents, concentrating on the risk-dominating issues. The work is reported in separate sub-project reports, the present is the final report of the methodological studies as well as a final report for the total project. The research has led to clarifications of the risk complex, and ameliorated the basis for advanced probabilistic safety analyses, specially for the emission risks (PSA level 2) which are being studied at the Swedish plants. A new method has been tried for analysis of complicated accident courses, giving a possibility for systematic evaluation of the impact of different important phenomena (e.g. melt-through, high pressure melt-through with direct heating of the containment atmosphere, steam explosions). In this method, the phenomena are looked upon as top events of a 'phenomena-tree', illustrating how various conditions must be met before the top-event can happen. This method has been useful, in particular for applying 'expert estimates'. 47 refs

Vacuum extractor has been increasingly used over the last decades and is acknowledged as a risk factor for shoulder dystocia (SD). In this meta-analysis we assess the actual risk of SD following a vacuum delivery compared to spontaneous vaginal delivery (SVD) and forceps. Systematic literature search (English literature only) on MEDLINE, EMBASE, ScienceDirect, the Cochrane library and ClinicalTrials.gov conducted up to May 2015. Key search terms included: Operative/Vacuum/Forceps delivery [Mesh] and shoulder dystocia and subheadings. 2 stage-process study selection. We included only studies where data concerning the occurrence of SD following operative vaginal delivery were reported as adjusted odds ratio (AOR) and no significant difference in confounding factors for SD was recorded. Included trials clustered according to the delivery mode (1) vacuum vs. SVD, (2) forceps vs. vacuum. Methodological quality of each study evaluated with the Newcastle-Ottawa System (NOS). 87 potentially relevant papers. After applying inclusion and exclusion criteria only 7 were selected for the meta-analysis. Vacuum delivery appeared associated with a higher risk of SD than SVD in both fixed and random model (OR 2.87 and 2.98 respectively). No difference in the rate of SD was found between vacuum and forceps (p>0.05). Vacuum extractor carries an increased risk of SD compared with spontaneous vaginal delivery whereas the occurrence of SD does not seem to vary following vacuum or forceps.

'This report summarizes the first year''s progress of research funded under the Department of Energy''s Environmental Management Science Program. The research was initiated to better determine ecological risks from toxic and radioactive contaminants. More precisely, the research is designed to determine the relevancy of sublethal cellular damage to the performance of individuals and to identify characteristics of non-human populations exposed to chronic, low-level radiation, as is typically found on many DOE sites. The authors propose to establish a protocol to assess risks to non-human species at higher levels of biological organization by relating molecular damage to more relevant responses that reflect population health. They think that they can achieve this by coupling changes in metabolic rates and energy allocation patterns to meaningful population response variables, and by using novel biological dosimeters in controlled, manipulative dose/effects experiments. They believe that a scientifically defensible endpoint for measuring ecological risks can only be determined once its understood the extent to which molecular damage from contaminant exposure is detrimental at the individual and population levels of biological organization.'

Higher education is associated with a lower risk of dementia, possibly because of a higher tolerance to subclinical neurodegenerative pathology. Whether higher education also protects against dementia after clinical stroke or transient ischemic attack (TIA) remains unknown. Within the population-based Rotterdam Study, 12,561 participants free of stroke, TIA and dementia were followed for occurrence of stroke, TIA and dementia. Across the levels of education, associations of incident stroke or TIA with subsequent development of dementia and differences in cognitive decline following stroke or TIA were investigated. During 124,862 person-years, 1,463 persons suffered a stroke or TIA, 1,158 persons developed dementia, of whom 186 developed dementia after stroke or TIA. Risk of dementia after a stroke or TIA, compared to no stroke or TIA, was highest in the low education category (hazards ratio [HR] 1.46, 95% CI 1.18-1.81) followed by intermediate education category (HR 1.36, 95% CI 1.03-1.81). No significant association was observed in the high education category (HR 0.62, 95% CI 0.25-1.54). In gender stratified analyses, decrease in risk of dementia with increasing education was significant only in men. Higher education is associated with a lower risk of dementia after stroke or TIA, particularly in men, which might be explained by a higher cognitive reserve. © 2016 S. Karger AG, Basel.

Full Text Available Objective: to analyze the association between high levels of stress and the frequency of cardiovascular risk factors in employees of a higher education institution. Methods: this is a cross-sectional study with 201 employees of a university. A form containing socioeconomic data, the International Physical Activity Questionnaire (short version, the Alcohol Use Disorders Identification Test and the Work Stress Scale were used for data collection. Data analysis was performed using the probability ratio and One-way analysis of variance tests. Results: worrisome frequencies of cardiovascular risk factors were identified, in which sedentary lifestyle, excess weight, and increased abdominal circumference presented the most expressive indexes. Regarding the stressors evaluated, some of the employees had increased stress indexes, distributed between the medium and high levels. Conclusion: sedentary lifestyle, excess weight, and increased abdominal circumference presented expressive high indexes, without statistically significant associations with the level of stress.
Methodological Bases for Describing Risks of the Enterprise Business Model in Integrated Reporting

2017-12-01
Full Text Available The aim of the article is to substantiate the methodological bases for describing the business and accounting risks of an enterprise business model in integrated reporting for their timely detection and assessment, and develop methods for their leveling or minimizing and possible prevention. It is proposed to consider risks in the process of forming integrated reporting from two sides: first, risks that arise in the business model of an organization and should be disclosed in its integrated report; second, accounting risks of integrated reporting, which should be taken into account by members of the cross-sectoral working group and management personnel in the process of forming and promulgating integrated reporting. To develop an adequate accounting and analytical tool for disclosure of information about the risks of the business model and integrated reporting, their leveling or minimization, in the article a terminological analysis of the essence of entrepreneurial and accounting risks is carried out. The entrepreneurial risk is defined as an objective-subjective economic category that characterizes the probability of negative or positive consequences of economic-social-ecological activity within the framework of the business model of an enterprise under uncertainty. The accounting risk is suggested to be understood as the probability of unfavorable consequences as a result of organizational, methodological errors in the integrated accounting system, which present threat to the quality, accuracy and reliability of the reporting information on economic, social and environmental activities in integrated reporting as well as threat of inappropriate decision-making by stakeholders based on the integrated report. For the timely identification of business risks and maximum leveling of the influence of accounting risks on the process of formation and publication of integrated reporting, in the study the place of entrepreneurial and accounting risks in

2003-01-01
BACKGROUND AND PURPOSE: Lay people often mention stress as one of the most important risk factors for stroke. Stress might trigger a cerebrovascular event directly or could be associated with higher levels of blood pressure or an unfavorable lifestyle. To examine these possibilities, we analyzed...... the association between self-reported stress frequency and intensity and risk of stroke. METHODS: Data from the second examination, 1981 to 1983, of participants in the Copenhagen City Heart Study were analyzed with Cox regression after a mean of 13 years of follow-up. A total of 5604 men and 6970 women were...... included, and 929 first-ever strokes occurred, of which 207 (22%) were fatal within 28 days after onset of symptoms. The stress frequency categories were never/hardly ever, monthly, weekly, or daily. The stress intensity categories were never/hardly ever, light, moderate, or high. RESULTS: Subjects...

Rehabilitation can improve physical activity after stroke. However, patients may be more prone to falls and fractures because of balance and gait deficits. Few reports have studied the relationship between rehabilitation and subsequent fractures after ischemic stroke. To investigate whether post-stroke rehabilitation affects fracture risk. We conducted a population-based retrospective cohort study based on the Taiwan National Health Insurance Research Database. Patients with a newly diagnosed ischemic stroke between 2000 and 2012 were included. After propensity score matching, a total of 8,384 patients were enrolled. Half of the patients (4,192) received post-stroke rehabilitation within 1 month; the other half did not receive any post-stroke rehabilitation. Cox proportional hazards regression model was used to calculate hazard ratios (HRs) for fractures among patients with and without rehabilitation within 1 year after ischemic stroke. Patients were further stratified by sex and age (20-64 and ≥65 years). Patients receiving post-stroke rehabilitation had a higher incidence of fracture (6.2 per 100 person-years) than those who did not (4.1 per 100 person-years) after adjustment for sociodemographic and coexisting medical conditions [HR = 1.53, 95% confidence interval (CI) = 1.25-1.87, p rehabilitation had a significantly higher risk of fracture (HR = 1.62, 95% CI = 1.21-2.17, p = 0.001). Rehabilitation after ischemic stroke is associated with an increased fracture risk in older women.

This document describes the current status of probabilistic risk assessment (PRA) as practiced in the nuclear reactor regulatory process. The PRA studies that have been completed or are under way are reviewed. The levels of maturity of the methodologies used in a PRA are discussed. Insights derived from PRAs are listed. The potential uses of PRA results for regulatory purposes are discussed. This document was issued for comment in February 1984 entitled Probabilistic Risk Assessment (PRA): Status Report and Guidance for Regulatory Application. The comments received on the draft have been considered for this final version of the report

This report summarizes and extends the work reported in five unpublished draft reports: the accidental radiological risk of reprocessing spent fuel, mixed oxide fuel fabrication, the transportation of materials within the fuel cycle, and the disposal of nuclear wastes, and the routine atmospheric radiological risk of mining and milling uranium-bearing ore. Results show that the total risk contribution of the fuel cycle is only about 1% of the accident risk of the power plant and hence, with little error, the accident risk of nuclear electric power is that of the power plant itself. The power plant risk, assuming a very large usage of nuclear power by the year 2005, is only about 0.5% of the radiological risk of natural background. This work aims at a realistic assessment of the process hazards, the effectiveness of confinement and mitigation systems and procedures, and the associated likelihoods and estimated errors. The primary probabilistic estimation tool is fault tree analysis with the release source terms calculated using physical--chemical processes. Doses and health effects are calculated with the CRAC code. No evacuation or mitigation is considered: source terms may be conservative through the assumption of high fuel burnup (40,000 MWd/T) and short cooling (90 to 150 d); HEPA filter efficiencies are derived from experiments
Polo pony injuries: player-owner reported risk, perception, mitigation and risk factors.
Inness, C M; Morgan, K L
2015-07-01
Polo, one of the world's oldest sports, is unique in merging human skill and balance with animal agility and performance in a contact sport. These modern-day 'centaurs' offer medical, dental and veterinary scientists an unrivalled, if quirky, opportunity to collaborate. Collection of epidemiological data on injuries to UK polo riders and ponies is the first step. To measure the reported risk and risk factors for injuries to UK polo ponies, their perception and mitigation by player-owners. A retrospective cohort design and telephone interviews were used. Data on equine injuries, preseason training and risk perception were collected from a random sample of player-owners using a structured questionnaire. Injuries were defined as requiring veterinary treatment. Frequencies were represented as percentages and 95% confidence intervals (CIs). Risk factors for injuries were identified by univariable and multivariable analyses. The cumulative incidence of player-owner-reported injury was 10.6% (95% CI 8.4-12.7). Tendon injuries were most common (4.3%; 95% CI 2.9-5.7), followed by wounds and splints. The only risk factor was stabling all season (odds ratio 4.79; 95% CI 1.46-15.73). Tendon injuries were perceived as the major risk and hard ground the most important risk factor. Risk mitigation practices were bandaging before exercise (45.7%; 95% CI 34.8-56.5), checking tendons (84.0%; 95% CI 76.0-91.9), cold hosing (40.7%; 95% CI 30.0-51.4), bandaging (38.3%; 95% CI 27.7-48.9) and using clays and coolants after exercise (24.7%; 15.3-34.1). Cuts and wounds were considered most frequent by only 2.5% (95% CI 0.0-3.6) of players but were the second most common injury, accounting for 21.6% of veterinary treatments. Splints accounted for 12.5% of injuries. The risk of injury to polo ponies is similar to that in the general horse population; musculoskeletal injuries, particularly tendon injuries, are most common, followed by wounds and splints. The association between stabling and

The linear, nonthreshold extrapolation from a dose-response relationship for ionizing radiation derived at higher doses to doses for which regulatory standards are proposed is being challenged by some scientists and defended by others. It appears that the risks associated with exposures to doses of interest are below the risks that can be measured with epidemiologic studies. Therefore, many have looked to biology to provide information relevant to risk assessment. The workshop reported here, ''The Impact of biology on Risk Assessment,'' was planned to address the need for further information by bringing together scientists who have been working in key fields of biology and others who have been contemplating the issues associated specifically with this question. The goals of the workshop were to summarize and review the status of the relevant biology, to determine how the reported biologic data might influence risk assessment, and to identify subjects on which more data is needed
Online reporting and assessing new occupational health risks in SIGNAAL.
Lenderink, A F; Keirsbilck, S; van der Molen, H F; Godderis, L
2015-11-01
Changes in work and working conditions continuously give rise to new work-related health risks. Without sufficient knowledge of these, opportunities for prevention and intervention may be missed. To develop, implement and evaluate an online tool called SIGNAAL for reporting and assessment of new work-related health risks by occupational health physicians and experts in the Netherlands and Belgium. Development and implementation of SIGNAAL to allow both easy and sufficient detailed reporting by occupational health physicians and structured and transparent assessment by occupational health experts. A new work-related health risk is defined as a work-related disease due to specific exposure in a specific work setting not described in the literature before. The online reporting and assessment tool proved to be a feasible means of reporting possible new combinations of health problems and exposures in the work situation. Eleven of the 15 cases reported until October 2014 were fully assessed: one was an entirely new work-related disease, four were known but uncommon work-related diseases, five were known but new in the reported work situation and one was a well-known work-related disease. An online reporting system used in an occupational health setting can provide insight into new work-related health risks by creating a structured way to gather, report and assess new combinations of health problems and exposure in the workplace. © The Author 2015.

The United Kingdom (UK) has one of the highest prevalence of asthma in the world, which represents a significant economic and societal burden. Reduced ventilation resulting from increased energy efficiency measures acts as a modifier for mould contamination and risk of allergic diseases. To our knowledge no previous study has combined detailed asset management property and health data together to assess the impact of household energy efficiency (using the UK Government's Standard Assessment Procedure) on asthma outcomes in an adult population residing in social housing. Postal questionnaires were sent to 3867 social housing properties to collect demographic, health and environmental information on all occupants. Detailed property data, residency periods, indices of multiple deprivation (IMD) and household energy efficiency ratings were also investigated. Logistic regression was used to calculate odds ratios and confidence intervals while allowing for clustering of individuals coming from the same location. Eighteen percent of our target social housing population were recruited into our study. Adults had a mean age of 59 (SD±17.3) years and there was a higher percentage of female (59%) and single occupancy (58%) respondents. Housing demographic characteristics were representative of the target homes. A unit increase in household Standard Assessment Procedure (SAP) rating was associated with a 2% increased risk of current asthma, with the greatest risk in homes with SAP >71. We assessed exposure to mould and found that the presence of a mouldy/musty odour was associated with a two-fold increased risk of asthma (OR 2.2 95%; CI 1.3-3.8). A unit increase in SAP led to a 4-5% reduction in the risk of visible mould growth and a mouldy/musty odour. In contrast to previous research, we report that residing in energy efficient homes may increase the risk of adult asthma. We report that mould contamination increased the risk of asthma, which is in agreement with existing

Full Text Available The primary purpose of this study was to identify potential risk factors for sports injuries in professional basketball. An observational retrospective cohort study involving a male professional basketball team, using game tracking data was conducted during three consecutive seasons. Thirty-three professional basketball players took part in this study. A total of 29 time-loss injuries were recorded during regular season games, accounting for 244 total missed games with a mean of 16.26 ± 15.21 per player and season. The tracking data included the following variables: minutes played, physiological load, physiological intensity, mechanical load, mechanical intensity, distance covered, walking maximal speed, maximal speed, sprinting maximal speed, maximal speed, average offensive speed, average defensive speed, level one acceleration, level two acceleration, level three acceleration, level four acceleration, level one deceleration, level two deceleration, level three deceleration, level four deceleration, player efficiency rating and usage percentage. The influence of demographic characteristics, tracking data and performance factors on the risk of injury was investigated using multivariate analysis with their incidence rate ratios (IRRs. Athletes with less or equal than 3 decelerations per game (IRR, 4.36; 95% CI, 1.78-10.6 and those running less or equal than 1.3 miles per game (lower workload (IRR, 6.42 ; 95% CI, 2.52-16.3 had a higher risk of injury during games (p < 0.01 in both cases. Therefore, unloaded players have a higher risk of injury. Adequate management of training loads might be a relevant factor to reduce the likelihood of injury according to individual profiles.

1996-06-01
This report is one of five reports issued in 1996 that provide follow- up information to the Phase 1 Remedial Investigation (RI) Report for Waste Area Grouping (WAG) 2 at Oak Ridge National Laboratory (ORNL). The five reports address areas of concern that could cause potential human health risk and ecological risk within WAG2 at ORNL. The purpose of this report is to present a summary of the human health risk assessment results based on the data collected for the WAG 2 Phase 1 RI. Estimates of risk are provided based on measured concentrations in the surface water, floodplain soil, and sediment of White Oak Creek, Melton Branch, and their tributaries. The human health risk assessment methodology used in this risk assessment is based on Risk Assessment Guidance for Superfund (RAGS). First, the data for the different media are elevated to determine usability for risk assessment. Second, through the process of selecting chemicals of potential concern (COPCs), contaminants to be considered in the risk assessment are identified for each assessment of exposure potential is performed, and exposure pathways are identified. Subsequently, exposure is estimated quantitatively, and the toxicity of each of the COPCs is determined. The results of these analyses are combined and summarized in a risk characterization

The evolution of information and communication technologies (ICT) nowadays has changed the life style of human living. The current modern societies have adopted ICT as an important thing that they are really needed in their life, especially as a tool to be used for communications activity. However, unfortunately ICT also exposed its user in circumstances of risk, threats and vulnerability. This paper will discuss the risk and threats to the users who are using social media as a medium to communicate. In this paper, the fraction of user will be divided by two types which are gender and working experience. The data that obtained from the distributed of questionnaires among respondent will be analysed by using SPSS. Data will be analysed by using two-way ANOVA statistic in order to examine the significant level in between gender and working experience as an independent variable in this study with the level of threats in cybersecurity risk towards lecturers who are working in higher education institutions in Malaysia. This article also will provide an empirical data and will be referred to another researcher in the future for their further research perhaps.

The APRI-project started in 1992 with participation of the Swedish Nuclear Power Inspectorate (SKI) and the Swedish utilities. The Finnish utility TVO joined the project in 1993. The aim of the project has been to work with phenomenological questions in severe accidents, concentrating on the risk-dominating issues. The work is reported in separate sub-project reports, the present is the final report of the methodological studies as well as a final report for the total project. The research has led to clarifications of the risk complex, and ameliorated the basis for advanced probabilistic safety analyses, specially for the emission risks (PSA level 2) which are being studied at the Swedish plants. A new method has been tried for analysis of complicated accident courses, giving a possibility for systematic evaluation of the impact of different important phenomena (e.g. melt-through, high pressure melt-through with direct heating of the containment atmosphere, steam explosions). In this method, the phenomena are looked upon as top events of a `phenomena-tree`, illustrating how various conditions must be met before the top-event can happen. This method has been useful, in particular for applying `expert estimates`. 47 refs.

A questionnaire survey was carried out among 1041 students in secondary schools and colleges in Dar-es-Salaam, Tanzania to evaluate the relationship between HIV-risky sexual behaviour and anti-condom bias, as well as with AIDS-related information, knowledge, perceptions and attitudes. Self-reportedly, 54% of students (75% of the boys and 40% of the girls) were sexually active, 39% had a regular sexual partner and 13% had multiple partners in the previous year. The condom use rate was higher than previous reports. However, 30% of sexually active respondents did not always use condoms (Risk-1 behaviour) and 35% of those with multiple partners in the previous year did not always use condoms (Risk-2 behaviour). Multiple logistic regression analyses indicated that 'sex partner hates condom' had association with both Risk-1 behaviour (OR 2.47; 95% CI 1.58-3.85) and Risk-2 behaviour (OR 2.47; 95% CI 1.10-5.48). 'Use of condom prevents HIV infection' also had association with both Risk-1 behaviour (OR 2.09; 95% CI 1.19-3.67) and Risk-2 behaviour (OR 3.73; 95% CI 1.28-11.03). Students engaging in risky behaviour were aware of the risk, even though they failed to change their behaviour. Reasons for the AIDS epidemic among Tanzanian students and the importance of more effective AIDS education are also discussed.

To study the association of M235T (rs699) and T174M (rs4762) polymorphisms of the angiotensinogen (AGT) gene with the risk of cerebral stroke (CS) in the Russians of the Central Chernozem Region. A total of 638 DNA samples obtained from 353 patients with CS and 285 sex- and age-matched healthy individuals were examined. The polymorphisms were genotyped by polymerase chain reaction (T174M) and TaqMan allelic discrimination (M235T) assays. Heterozygous AGT 174TM genotype carriers were found to be at a higher risk for CS (odd ratio (OR) = 1.52; 95% confidence interval (CI), 1.08-2.15; p = 0.02). A gender-stratified analysis showed that the mutant 174M allele (OR = 1.86; 95% CI, 1.14-3.03, p = 0.01) and variant 174TM and 174MM genotypes (OR = 1.86; 95% CI, 1.09-3.20; p = 0.02) were associated with the higher risk of cerebral stroke in women. The association of AGT T174M polymorphism with the risk of CS was first found; but the higher risk of the disease in the carriers of variant alleles and genotypes was observed in the women only.

The incidence of cryptosporidiosis is highest in children <5 years, yet little is known about disease patterns across urban and rural areas of Australia. In this study, we examine whether the risk of reported cryptosporidiosis in children <5 years varies across an urban-rural gradient, after controlling for season and gender. Using Australian data on reported cryptosporidiosis from 2001 to 2012, we spatially linked disease data to an index of geographic remoteness to examine the geographic variation in cryptosporidiosis risk using negative binomial regression. The Incidence Risk Ratio (IRR) of reported cryptosporidiosis was higher in inner regional (IRR 1.4 95% CI 1.2-1.7, p < 0.001), and outer regional areas (IRR 2.4 95% CI 2.2-2.9, p < 0.001), and in remote (IRR 5.2 95% CI 4.3-6.2, p < 0.001) and very remote (IRR 8.2 95% CI 6.9-9.8, p < 0.001) areas, compared to major cities. A linear test for trend showed a statistically significant trend with increasing remoteness. Remote communities need to be a priority for future targeted health promotion and disease prevention interventions to reduce cryptosporidiosis in children <5 years.

porous and permeable) injection depths within the overall formation. Less direct implications include the vertical position of the Potosi within the rock column and the absence of a laterally extensive shale caprock immediately overlying the Potosi. Based on modeling work done partly in association with this risk report, risks that should also be evaluated include the ability of available methods to predict and track the development of a CO2 plume as it migrates away from the injection point(s). The geologic and hydrodynamic uncertainties present risks that are compounded at the stage of acquiring necessary drilling and injection permits. It is anticipated that, in the future, a regional geologic study or CO2-emitter request may identify a small specific area as a prospective CCS project site. At that point, the FEPs lists provided in this report should be evaluated by experts for their relative levels of risk. A procedure for this evaluation is provided. The higher-risk FEPs should then be used to write project-specific scenarios that may themselves be evaluated for risk. Then, actions to reduce and to manage risk can be described and undertaken. The FEPs lists provided as Appendix 2 should not be considered complete, as potentially the most important risks are ones that have not yet been thought of. But these lists are intended to include the most important risk elements pertinent to a Potosi-target CCS project, and they provide a good starting point for diligent risk identification, evaluation, and management.

This was a prospective study including 85 patients with PTC of intermediate risk and higher risk features: tumor greater than 1 cm and aggressive histological subtype or vascular invasion; and/or more than three positive lymph node (LN) or LN greater than 1.5 cm or showing macroscopic extracapsular extension; and/or a combination of tumor greater than 4 cm, microscopic extrathyroidal extension, aggressive histology, and LN metastases (cN1). After thyroidectomy, all patients had nonstimulated Tg of at least 0.3 ng/ml and ultrasonography showed no anomalies. When evaluated 12 months after RAI therapy, an excellent response to initial therapy was achieved in 61 patients (71.7%). Structural disease was detected in five patients (5.9%). During follow-up, 6/80 patients (7.5%) without structural disease 1 year after RAI developed relapse. In the last assessment, 80 patients (94.1%) had nonstimulated Tg less than 1 ng/ml and no evidence of structural disease. There was no case of death because of the tumor. Postoperative nonstimulated Tg was a predictive factor of the main outcome (structural disease 1 year after RAI or recurrence) and the best cut-off was 1.8 ng/ml (sensitivity: 72.7%, specificity: 83.4%, negative predictive value: 95.4%). In patients with PTC of intermediate risk with higher risk features treated with 3.7 GBq RAI, postoperative nonstimulated Tg up to 1.8 ng/ml was a predictor of low risk of structural disease 1 year after therapy or recurrence.

Full Text Available The purpose of financial reports is to provide useful information to users; the utility of information is defined through the qualitative characteristics (fundamental and enhancing. The financial crisis emphasized the limits of financial reporting which has been unable to prevent investors about the risks they were facing. Due to the current changes in business environment, managers have been highly motivated to rethink and improve the risk governance philosophy, processes and methodologies. The lack of quality, timely data and adequate systems to capture, report and measure the right information across the organization is a fundamental challenge for implementing and sustaining all aspects of effective risk management. Starting with the 80s, the investors are more interested in narratives (Notes to financial statements, than in primary reports (financial position and performance. The research will apply a regression model for assessment of risk reporting by the professional (accounting and taxation services for major companies from Romania during the period 2009 – 2013.

Full Text Available Reputation is a complex and multidimensional concept that may be organized in downside and upside reputational risk. In this article, we present a formal modelling for the management capabilities of environmental management and reporting over reputational risk, considering that reputational risk is becoming increasingly important for organizations and it directly depends on the information available about companies’ environmental performances. As long as the effectiveness of communication and disclosure plays a key role in the process, the usefulness of environmental management and reporting as a hedging instrument for reputational risk is addressed through different levels of information transparency. When considering a scenario of voluntary reporting, we show that environmentally concerned companies can reduce the cost of environmental management as a reputational risk strategy, as well as reducing the potential loss of reputational value from reputational threats and increasing the potential profit from reputational opportunities. In the context of mandatory reporting, we highlight the role of assurance companies as bearers of the risk of bad reputations for non-concerned companies. As a result, this novel approach applies theoretical oriented research from options theory to reputational risk management literature, so that it benefits from the option’s well known theory, robustness, and conclusions.

Since the 18th century, the Republic of Haiti has experienced numerous tropical cyclones. In 2011, the United Nations Global Assessment Report on Disaster Risk Reduction outlined that the worldwide physical exposure to natural hazards, which includes tropical storms and hurricanes in Haiti, increased by 192 per cent between 1970 and 2010. Now, it can be hypothesized that the increased physical exposure to cyclones that made landfall in Haiti has affected the country's development path. This study shows that tropical storm risks in Haiti increased due to more physical exposure of the population in urban areas rather than a higher cyclone frequency in the proximity of Hispaniola island. In fact, the population density accelerated since the second half of the 20th century in regions where historically more storms made landfall, such as in the departments Ouest, Artibonite, Nord and Nord-Ouest including Haiti's four largest cities: Port-au-Prince, Gonaïves, Cap-Haïtien and Port-de-Paix. Thus, urbanization in and migration into storm hazard prone areas could be considered as one of the major driving forces of Haiti's fragility.

This research examines how risk information disclosure is changing in annual report before and after East Japan Great Earthquake Disaster. Company voluntary disclose risk information in annual report. Manager can decide a style and items of risk information. This paper explores risk information disclosures of Tokyo Electric Power Company, Chubu Power Electric Company, Kansai Electric Power Company and Toyota Motor Corporation. The managers except Tokyo Electric Company are likely to disclose own catastrophe risk before the disaster. However, they do not try to reduce their risk. Corporations' risk information do not link with own risk management. (author)

Likewise, the results obtained emphasize the complexity of the voluntary revelation of risks. While an extended management board might improve the provision of more detailed information about the risks required by the current regulation, it tends to adopt a conservative policy of reporting concerning the voluntary disclosure. Moreover, we show the relevance of transparency as a deterrent for providing voluntary information by larger companies, due to the concerns about negative strategic repercussions.
Why do perfectionists have a higher burnout risk than others? The mediational effect of workaholism

Full Text Available Previous research has revealed that perfectionists have a higher burnout risk than others, but the mechanisms accounting for this association have rarely been examined. The present study proposes that workaholism mediates this relation, as previous research revealed that (a perfectionists are more likely to be workaholics than others, and (b workaholics have a higher burnout risk than others. Using cross-sectional data from 199 Dutch managers, regression analyses revealed that holding high standards towards oneself (a self-directed indicator of perfectionism was unrelated to any of the three dimensions of the Maslach Burnout Inventory. However, high concern over making mistakes in the face of others (representing socially prescribed perfectionism was systematically associated with high levels of burnout and workaholism. Moreover, workaholism was positively associated with high levels of exhaustion. Subsequent mediation analysis revealed that the association between (the socially prescribed aspect of perfectionism and burnout (emotional exhaustion was mediated by workaholism.

Full Text Available Universities should actively participate in disseminating and fostering a culture for disaster risk management (DRM among students and the community. Particularly in countries with high levels of risk, education plays a key role in raising awareness on the importance of preventing and implementing conscious risk management. Though the incorporation of DRM into the curricula, education programs become a mechanism to prepare students from a perspective of strengthening of values, citizenship, and social sensibility towards how disaster represents a disruption of the functioning of a community and impairs business activity. This paper presents the proposal for the integration of DRM of a private university in Mexico, one of the countries particularly susceptible to extreme hydrometereological and geological events. The proposal includes a concentration area for undergraduate business students, a mandatory introductory course for all business majors, and for the business community an executive education program for SMEs

Mixed evidence exists with respect to the association between household food insecurity (HFIS) and obesity in low-to-middle income countries (LMICs), particularly among women. This study aimed to measure socioeconomic correlates of HFIS and explores its association with dietary intake and odds of obesity among mothers in Lebanon, a middle-income country undergoing nutrition transition. A cross-sectional study was conducted among a representative sample of households (n = 378) in Beirut, Lebanon. Surveys were completed with mothers of children Food Insecurity Access Scale (HFIAS). Dietary intake was assessed using the multiple pass 24-h recall method. Associations between HFIS (food vs food insecure) and socio-demographic characteristics were reported using crude and adjusted odds ratios. The odds of consuming food secure and food insecure households were explored. In addition, logistic regression analyses were conducted to explore the association of HFIS with obesity (BMI ≥ 30 kg/m2) and at-risk waist circumference (WC ≥ 80 cm) among mothers. HFIS was found among 50% of study sample and was inversely associated with household income and mother's educational level, even after adjusting for other socioeconomic variables (p food insecure households reported consuming significantly less dairy products, fruits, and nuts yet more breads and sweets; and they had higher odds of consuming food insecure mothers had 1.73 odds of obesity (95% CI: 1.02-2.92) compared to food secure mothers. High HFIS prevalence was reported among urban Lebanese households. Mothers from food insecure households had a high risk of dietary inadequacy and obesity. Adequate evidence-based public health strategies are needed to reduce the vulnerability of mothers to food insecurity in LMIC settings and alleviate their risk of a high burden of nutrient insecurity and obesity.

To investigate the association between material deprivation and injury sustained in violence by adolescents aged 11-17 years. Computerised data relating to gender, attendance date and resident postcode of all patients aged 11-17 years who received treatment for violence-related injuries at seven emergency departments (ED) in South Wales over 12 months, 1 October 2005 to 30 September 2006, were studied. The resident populations, by electoral division of three unitary authorities in Wales, Cardiff, Swansea and Newport, were obtained from the NHS administrative register. The relationships between demographic variables and material deprivation as measured by the Townsend deprivation index were analysed. Altogether 699 (475 boys; 224 girls) adolescents aged 11-17 years resident in Cardiff, Swansea and Newport attended ED in South Wales following violence. Boys and girls living in the most deprived areas had higher assault injury rates compared with those living in the most affluent areas. In the context of sustaining violence-related injury, material deprivation affected girls aged 11-17 years to a much greater extent (Cardiff most deprived vs most affluent rate ratio 6.31, Swansea 10.11, Newport 2.90) than boys of the same age group (Cardiff most deprived vs most affluent rate ratio 2.02, Swansea 7.74, Newport 1.74). Material deprivation was associated with a higher risk of violence-related injury for adolescent girls compared with adolescent boys. Risk-taking behaviour for adolescent boys and girls may be different under different socioeconomic conditions. Violence prevention efforts should focus more on tackling neighbourhood inequalities, particularly those related to material deprivation in adolescent girls.
Longitudinal AddiQoL scores may identify higher risk for adrenal crises in Addison's disease.

Several studies have shown a reduced quality of life (QoL) in patients with Addison's disease (AD), but investigations of QoL over a long-term course are lacking. Adrenal crises (AC) are life-threatening complications in AD. The purpose of this prospective study was to test whether the repeated use of QoL-questionnaires can detect prodromal periods of an AC. 110 patients with AD were asked to complete the disease specific-QoL questionnaire AddiQoL and a short questionnaire about adverse events once monthly over a period of ten months. AC was defined if at least two of the following symptoms were reported: (a) hypotension, (b) nausea or vomiting, (c) severe fatigue, (d) documented hyponatremia, hyperkalemia, or hypoglycemia, and subsequent parenteral glucocorticoid administration was carried out. Prevalence of AC was 10.9/100 patient years. AddiQoL scores in patients with AC showed a trend (p = 0,08) to a wider fluctuation over time. Subjective precrises not meeting the criteria for AC were reported by 31 patients who had significantly lower AddiQoL scores (p = 0,018). These are the first data showing the course of QoL during a period of ten months in patients with AD. Incidence of AC exceeds previous data. Our data show, that subjective precrises in AD associate with lower QoL. AC, as well as precrises affect intraindividual AddiQol-scores over time with a trend to a stronger fluctuation. Longitudinal AddiQol scores and self-reporting of precrises via patient diaries are additional clinical tools to identify higher risk for critical events.
Using a quantitative risk register to promote learning from a patient safety reporting system.
Mansfield, James G; Caplan, Robert A; Campos, John S; Dreis, David F; Furman, Cathie

Patient safety reporting systems are now used in most health care delivery organizations. These systems, such as the one in use at Virginia Mason (Seattle) since 2002, can provide valuable reports of risk and harm from the front lines of patient care. In response to the challenge of how to quantify and prioritize safety opportunities, a risk register system was developed and implemented. Basic risk register concepts were refined to provide a systematic way to understand risks reported by staff. The risk register uses a comprehensive taxonomy of patient risk and algorithmically assigns each patient safety report to 1 of 27 risk categories in three major domains (Evaluation, Treatment, and Critical Interactions). For each category, a composite score was calculated on the basis of event rate, harm, and cost. The composite scores were used to identify the "top five" risk categories, and patient safety reports in these categories were analyzed in greater depth to find recurrent patterns of risk and associated opportunities for improvement. The top five categories of risk were easy to identify and had distinctive "profiles" of rate, harm, and cost. The ability to categorize and rank risks across multiple dimensions yielded insights not previously available. These results were shared with leadership and served as input for planning quality and safety initiatives. This approach provided actionable input for the strategic planning process, while at the same time strengthening the Virginia Mason culture of safety. The quantitative patient safety risk register serves as one solution to the challenge of extracting valuable safety lessons from large numbers of incident reports and could profitably be adopted by other organizations.

Full Text Available The incidence of cryptosporidiosis is highest in children <5 years, yet little is known about disease patterns across urban and rural areas of Australia. In this study, we examine whether the risk of reported cryptosporidiosis in children <5 years varies across an urban-rural gradient, after controlling for season and gender. Using Australian data on reported cryptosporidiosis from 2001 to 2012, we spatially linked disease data to an index of geographic remoteness to examine the geographic variation in cryptosporidiosis risk using negative binomial regression. The Incidence Risk Ratio (IRR of reported cryptosporidiosis was higher in inner regional (IRR 1.4 95% CI 1.2–1.7, p < 0.001, and outer regional areas (IRR 2.4 95% CI 2.2–2.9, p < 0.001, and in remote (IRR 5.2 95% CI 4.3–6.2, p < 0.001 and very remote (IRR 8.2 95% CI 6.9–9.8, p < 0.001 areas, compared to major cities. A linear test for trend showed a statistically significant trend with increasing remoteness. Remote communities need to be a priority for future targeted health promotion and disease prevention interventions to reduce cryptosporidiosis in children <5 years.

Carbon capture and storage (CCS) is considered as a possibility to struggle against greenhouse effect and therefore against climate change. This process is here presented as comprising three main periods: exploitation during 40 to 50 years which itself comprises three phases (design, injection and closure), memory during about 300 years, and a long term period (700 to 800 years during which the existence of the storage and its associated risks will be forgotten). This study concerns the injection phase of the first period and some of its associated risks: leakages, thermal-hydro-mechanical-chemical disturbances at the vicinity of the storage. The report gives an overview of CO 2 geological capture and storage (capture, transport, injection, storage, foreseen storage media, nature of the injected fluid, regulations, returns on experience), identifies the associated risks, discusses issues of assessment of risks related to well leakages and to disturbances at the vicinity of the well (mechanical, physical and chemical, bacteriological risks)

History of smoking has been implicated as a risk factor for reconstructive complications in nipple-sparing mastectomy (NSM), however there have been no direct analyses of outcomes in smokers and nonsmokers. All patients undergoing NSM at New York University Langone Medical Center from 2006 to 2014 were identified. Outcomes were compared for those with and without a smoking history and stratified by pack-year smoking history and years-to-quitting (YTQ). A total of 543 nipple-sparing mastectomies were performed from 2006 to 2014 with a total of 49 in patients with a history of smoking. Reconstructive outcomes in NSM between those with and without a smoking history were equivalent. Those with a smoking history were not significantly more likely to have mastectomy flap necrosis (p = 0.6251), partial (p = 0.8564), or complete (p = 0.3365) nipple-areola complex (NAC) necrosis. Likewise, active smokers alone did not have a higher risk of complications compared to nonsmokers or those with smoking history. Comparing nonsmokers and those with a less or greater than 10 pack-year smoking history, those with a > 10 pack-year history had significantly more complete NAC necrosis (p = 0.0114, smoking history or >5 YTQ prior to NSM were equivalent to those without a smoking history. We demonstrate that NSM may be safely offered to those with a smoking history although a > 10 pack-year smoking history or <5 YTQ prior to NSM may impart a higher risk of reconstructive complications, including complete NAC necrosis. © 2017 Wiley Periodicals, Inc.

Full Text Available Abstract Background Despite increasing interest and publication of risk-adjusted hospital mortality rates, the relationship with underlying quality of care remains unclear. We undertook a systematic review to ascertain the extent to which variations in risk-adjusted mortality rates were associated with differences in quality of care. Methods We identified studies in which risk-adjusted mortality and quality of care had been reported in more than one hospital. We adopted an iterative search strategy using three databases – Medline, HealthSTAR and CINAHL from 1966, 1975 and 1982 respectively. We identified potentially relevant studies on the basis of the title or abstract. We obtained these papers and included those which met our inclusion criteria. Results From an initial yield of 6,456 papers, 36 studies met the inclusion criteria. Several of these studies considered more than one process-versus-risk-adjusted mortality relationship. In total we found 51 such relationships in a widen range of clinical conditions using a variety of methods. A positive correlation between better quality of care and risk-adjusted mortality was found in under half the relationships (26/51 51% but the remainder showed no correlation (16/51 31% or a paradoxical correlation (9/51 18%. Conclusion The general notion that hospitals with higher risk-adjusted mortality have poorer quality of care is neither consistent nor reliable.

We aimed to assess comprehensively the prevalence of perinatal risks experienced by a potentially high-risk yet understudied population of children domestically adopted in the United States. Data are from participant report and medical records from mothers (n = 580) who completed a domestic adoption placement with nonrelatives at or near birth (Mean placement age = 7 days). We describe a comprehensive measure of perinatal risks, including divergences from previous assessment tools and the incorporation of multiple reporters, and report the prevalence of various types of perinatal risks. The prevalence of each specific risk factor was generally low, although several risks were more prevalent in this sample than estimates from nationally representative publicly available data. Nearly the entire sample (99%) experienced some type of risk exposure. Birth mothers who placed their children for adoption domestically in the US experience higher levels of perinatal risks than the national average, but not for all specific types of risk. Thus, the developmental trajectories of children adopted domestically may systematically differ from the general population to the extent that these specific perinatal risks impact development.

The Fuel Cycle Risk Analysis Division of Sandia Laboratories is funded by the Nuclear Regulatory Commission (NRC) to develop a methodology for assessment of the long-term risks from radioactive waste disposal in deep, geologic media. The first phase of this work, which is documented in this report, involves the following: (1) development of analytical models to represent the processes by which radioactive waste might leave the waste repository, enter the surface environment and eventually reach humans and (2) definition of a hypothetical ''reference system'' to provide a realistic setting for exercise of the models in a risk or safety assessment. The second phase of this work, which will be documented in a later report, will involve use of the analytical models in a demonstration risk or safety assessment of the reference system. The analytical methods and data developed in this study are expected to form the basis for a portion of the NRC repository licensing methodology

To evaluate the association of snacking between main meals with the risk of developing metabolic syndrome. A dynamic prospective cohort study (the SUN Project; Seguimiento Universidad de Navarra). Snack consumption was evaluated using the question: 'Do you have the habit of snacking between main meals?' Metabolic syndrome was defined according to the updated harmonizing criteria. We estimated multivariable-adjusted relative risks (RR) of metabolic syndrome and their 95 % confidence intervals using Poisson regression models. An exploratory factor analysis was also used to identify patterns of snacking. University of Navarra, Spain. The study included 6851 university graduates, initially free of metabolic syndrome, and followed-up them for a median of 8·3 years. Among our participants, 34·6% reported usual snacking between main meals. The cumulative incidence of metabolic syndrome was 5·1 % (9·5% among men and 2·8% among women). Snacking between main meals was significantly associated with higher risk for developing metabolic syndrome after multivariable adjustment (RR=1·44; 95%CI 1·18, 1·77). Higher adherence to an 'unhealthy snacking pattern' was also independently associated with increased incidence of metabolic syndrome (fourth quartile of adherence compared with non-snacking: RR=1·68; 95% CI 1·23, 2·29; P for trend metabolic syndrome development, especially when snacks contain foods of poor nutritional quality.
Disease awareness may increase risk of suicide in young onset dementia: A case report

Maria Alice Tourinho Baptista
Full Text Available ABSTRACT Studies report that people with young onset Alzheimer's disease (YOAD have higher levels of disease awareness compared to those with late onset AD. We report a case of a man with YOAD who had preserved awareness of disease, depression and risk of suicide associated with the development of the dementia. Cognitive functioning, disease severity, depressive symptoms and awareness of disease were assessed using validated measures. The person with YOAD showed a moderate level of disease severity and high degree of dependence for activities of daily living. There was recognition of memory problems and routine changes with presence of intense pessimism, low self-esteem and suicidal ideation. This case points to the existence of specific issues related to young onset dementia and the clinical importance of identifying and treating patients who might be aware of their condition.

The aim of this study was to investigate whether higher morale, i.e. future-oriented optimism, at baseline was associated with lower risk of depressive disorders five years later among very old people.Methods The Umeå85+/GErontological Regional Database, a population-based study with a longitudinal design, recruited participants in Sweden and Finland aged 85, 90 and ≥95 years. The sample in the present study included 647 individuals (89.1±4.4 years (Mean±SD), range 85-103). After five years, 216 were alive and agreed to a follow-up (92.6±3.4 years, range 90-104). The Philadelphia Geriatric Center Morale Scale (PGCMS) was used to assess morale. The depressive disorder diagnosis was determined according to DSM-IV based on medical records and interview data including assessment scales for depressive disorders. A number of sociodemographic, functional and health-related variables were analysed as possible confounders.Results For those with no depressive disorders at baseline, the only baseline variable significantly associated with depressive disorders five years later was the PGCMS score. A logistic regression model showed lower risk of depressive disorders five years later with higher baseline PGCMS scores (odds ratio 0.779 for one point increase in PGCMS, pfive years later).Conclusion Our results indicate that the higher the morale, the lower the risk of depressive disorders five years later among very old people. The PGCMS seems to identify those very old individuals at increased risk of depressive disorders five years later. Preventive measures could befocused on this group.

Nuclear Safety Commission's taskforce on 'Introduction of Safety Regulation Utilizing Risk Information' completed the interim report on its future subjects and directions in December 2005. Although current safety regulatory activities have been based on deterministic approach, this report shows the risk informed approach is expected to be very useful for making nuclear safety regulation and assurance activities reasonable and also for appropriate allocation of regulatory resources. For introduction of risk informed regulation, it also recommends pileups of experiences with gradual introduction and trial of the risk informed approach, improvement of plant maintenance rules and regulatory requirements utilizing risk information, and establishment of framework to assure quality of risk evaluation.

Despite our knowledge of barriers to the early stages of the transplant process, we have limited insight into patient-reported barriers to the prekidney transplant medical evaluation in populations largely at-risk for evaluation failure. One-hundred consecutive adults were enrolled at an urban, Midwestern transplant center. Demographic, clinical, and quality of life data were collected prior to patients visit with a transplant surgeon/nephrologist (evaluation begins). Patient-reported barriers to evaluation completion were collected using the Subjective Barriers Questionnaire 90-days after the initial medical evaluation appointment (evaluation ends), our center targeted goal for transplant work-up completion. At 90 days, 40% of participants had not completed the transplant evaluation. Five barrier categories were created from the 85 responses to the Subjective Barriers Questionnaire. Patient-reported barriers included poor communication, physical health, socioeconomics, psychosocial influences, and access to care. In addition, determinants for successful evaluation completion included being of white race, higher income, free of dialysis, a lower comorbid burden, and reporting higher scores on the Kidney Disease Quality of Life subscale role-emotional. Poor communication between patients and providers, and among providers, was the most prominent patient-reported barrier identified. Barriers were more prominent in marginalized groups such as ethnic minorities and people with low income. Understanding the prevalence of patient-reported barriers may aid in the development of patient-centered interventions to improve completion rates.

Environmental risk assessment can be used as a strategic tool to set environmental priorities and as a tactical tool to set environmental standards. This report is designed to inform Australian environmental managers about the techniques and applications of environmental risk assessment and to familiarize risk analysts with some of the issues that are of concern to environmental managers. The use of risk assessment is illustrated by applying its techniques to five case studies which include: risk from chemicals and from contaminated sites; risk to people and to the natural environment from development, such as uranium mining; climate change; and risk associated with political decision-making. Then, by considering Australian and overseas practice, a generic framework is presented within which environmental risk assessment in Australia can be undertaken, and possible methods of implementation are discussed. refs., 38 figs
Self-reported screen time and cardiometabolic risk in obese Dutch adolescents.

Full Text Available BACKGROUND: It is not clear whether the association between sedentary time and cardiometabolic risk exists among obese adolescents. We examined the association between screen time (TV and computer time and cardiometabolic risk in obese Dutch adolescents. METHODS AND FINDINGS: For the current cross-sectional study, baseline data of 125 Dutch overweight and obese adolescents (12-18 years participating in the Go4it study were included. Self-reported screen time (Activity Questionnaire for Adolescents and Adults and clustered and individual cardiometabolic risk (i.e. body composition, systolic and diastolic blood pressure, low-density (LDL-C, high-density (HDL-C and total cholesterol (TC, triglycerides, glucose and insulin were assessed in all participants. Multiple linear regression analyses were used to assess the association between screen time and cardiometabolic risk, adjusting for age, gender, pubertal stage, ethnicity and moderate-to-vigorous physical activity. We found no significant relationship between self-reported total screen time and clustered cardiometabolic risk or individual risk factors in overweight and obese adolescents. Unexpectedly, self-reported computer time, but not TV time, was slightly but significantly inversely associated with TC (B = -0.002; CI = [-0.003;-0.000] and LDL-C (B = -0.002; CI = [-0.001;0.000]. CONCLUSIONS: In obese adolescents we could not confirm the hypothesised positive association between screen time and cardiometabolic risk. Future studies should consider computer use as a separate class of screen behaviour, thereby also discriminating between active video gaming and other computer activities.

Childhood obesity is increasing especially in Latinos and early intervention is essential to prevent later obesity complications. Latino children (n = 201) recruited at two San Francisco hospitals were assessed at birth including infant anthropometrics and feeding practices and followed to age 9 with annual anthropometric assessments. We evaluated the relationship between perinatal risk factors and obesity at age 9 and chronic obesity (obesity at both 5 and 9 years). Higher birthweight [odds ratio (OR) 2.48, 95% confidence interval (CI) 1.06-5.81] and maternal pre-pregnancy body mass index (BMI) (OR 1.09, 95% CI 1.00-1.18) were associated with increased risk for obesity at 9 years. Higher maternal pre-pregnancy BMI (OR 1.10, 95% CI 1.01-1.20) was associated with chronic obesity. Additionally, prenatal depression symptoms were protective (OR 0.33, 95% CI 0.11-0.94) against chronic obesity. We found no association between maternal age and education, exclusive breastfeeding at 4-6 weeks, rapid infant weight gain, and obesity or chronic obesity. Perinatal risk factors for obesity including higher birthweight and maternal pre-pregnancy BMI persisted until age 9, whereas, other variables significant at age 5 in our cohort and other populations including exclusive breastfeeding and rapid infant weight gain were no longer associated with increased risk.

Full Text Available The nowadays accounting information user profile became more sophisticated and the financial reports face new challenges in accomplishing process to meet users’ needs. The purpose of financial reports is to provide useful information to users. According to International Accounting Standards Board, the utility of information is defined through the qualitative characteristics (fundamental and enhancing. The financial crisis emphasized the limits of financial reporting who has been unable to prevent investors about the risks they were facing. Some managers expressed reservations about the quality and relevance of corporate reporting, stating that the annual report is no longer a useful tool. Due to the current changes in business environment, managers have been highly motivated to rethink and improve the risk governance philosophy, processes and methodologies. The lack of quality, timely data and adequate systems to capture, report and measure the right information across the organization is a fundamental challenge to implementing and sustaining all aspects of effective risk management. Starting from 80s, the investors became more interested in narratives (Notes to financial statements, than in primary reports (financial position and performance. Our research suggests a framework for risk reporting with the main goal of improving the good practice in risk management field. Also, we will debate the relation between the qualitative characteristics of accounting information, transparency and risk, and explore the possibility of developing some good practices in risk reporting.

The Pune Children's Study aimed to test whether glucose and insulin measurements in childhood predict cardiovascular risk factors in young adulthood. We followed up 357 participants (75% follow-up) at 21 years of age who had undergone detailed measurements at 8 years of age (glucose, insulin, HOMA-IR and other indices). Oral glucose tolerance, anthropometry, plasma lipids, BP, carotid intima-media thickness (IMT) and arterial pulse wave velocity (PWV) were measured at 21 years. Higher fasting glucose, insulin and HOMA-IR at 8 years predicted higher glucose, insulin, HOMA-IR, BP, lipids and IMT at 21 years. A 1 SD change in 8 year variables was associated with a 0.10-0.27 SD change at 21 years independently of obesity/adiposity at 8 years of age. A greater rise in glucose-insulin variables between 8 and 21 years was associated with higher cardiovascular risk factors, including PWV. Participants whose HOMA-IR measurement remained in the highest quartile (n = 31) had a more adverse cardiovascular risk profile compared with those whose HOMA-IR measurement remained in the lowest quartile (n = 28). Prepubertal glucose-insulin metabolism is associated with adult cardiovascular risk and markers of atherosclerosis. Our results support interventions to improve glucose-insulin metabolism in childhood to reduce cardiovascular risk in later life.

Youth Participation and Injury Risk in Martial Arts.
Demorest, Rebecca A; Koutures, Chris
2016-12-01
The martial arts can provide children and adolescents with vigorous levels of physical exercise that can improve overall physical fitness. The various types of martial arts encompass noncontact basic forms and techniques that may have a lower relative risk of injury. Contact-based sparring with competitive training and bouts have a higher risk of injury. This clinical report describes important techniques and movement patterns in several types of martial arts and reviews frequently reported injuries encountered in each discipline, with focused discussions of higher risk activities. Some of these higher risk activities include blows to the head and choking or submission movements that may cause concussions or significant head injuries. The roles of rule changes, documented benefits of protective equipment, and changes in training recommendations in attempts to reduce injury are critically assessed. This information is intended to help pediatric health care providers counsel patients and families in encouraging safe participation in martial arts.

Response to stress can vary greatly between individuals. However, it remains unknown whether perceived impact of stress on health is associated with adverse health outcomes. We examined whether individuals who report that stress adversely affects their health are at increased risk of coronary heart disease (CHD) compared with those who report that stress has no adverse health impact. Analyses are based on 7268 men and women (mean age: 49.5 years, interquartile range: 11 years) from the British Whitehall II cohort study. Over 18 years of follow-up, there were 352 coronary deaths or first non-fatal myocardial infarction (MI) events. After adjustment for sociodemographic characteristics, participants who reported at baseline that stress has affected their health 'a lot or extremely' had a 2.12 times higher (95% CI 1.52-2.98) risk of coronary death or incident non-fatal MI when compared with those who reported no effect of stress on their health. This association was attenuated but remained statistically significant after adjustment for biological, behavioural, and other psychological risk factors including perceived stress levels, and measures of social support; fully adjusted hazard ratio: 1.49 (95% CI 1.01-2.22). In this prospective cohort study, the perception that stress affects health, different from perceived stress levels, was associated with an increased risk of coronary heart disease. Randomized controlled trials are needed to determine whether disease risk can be reduced by increasing clinical attention to those who complain that stress greatly affects their health.

Thus, the aim of this study was to compare if higher or smaller fibronectin type 3 domain-containing protein 5 (FNDC5)/irisin levels are associated with inflammatory and metabolic markers, caloric/macronutrient intake, physical fitness and type 2 diabetes mellitus (T2DM) risk in obese middle-aged men, and also to correlate all variables analyzed with FNDC5/irisin. On the basis of a cluster study, middle-aged obese men (IMC: 31.01 ± 1.64 kg/m2) were divided into groups of higher and smaller levels of FNDC5/irisin. The levels of leptin, resistin, adiponectin, tumor necrosis factor alpha (TNFα), interleukin 6 and 10 (IL6, IL10), lipopolysaccharide (LPS), glucose, insulin, glycated hemoglobin, insulin resistance and sensibility, lipid profile, risk of T2DM development, body composition, rest energy expenditure, caloric/macronutrient intake and physical fitness were measured. The higher FNDC5/ irisin group presented improved insulin sensibility (homeostasis model assessment - sensibility (HOMA-S) (p = 0.01) and QUICKI index (p risk of T2DM development (p = 0.02), tendency to decrease serum resistin (p = 0.08) and significant lower LPS levels (p = 0.02). Inverse correlations between FNDC5/irisin and body weight (r -0.46, p = 0.04), neck circumference (r -0.51, p = 0.02), free fat mass (r -0.49, p = 0.02), triglycerides (r -0.43, p = 0.05) and risk of developing T2DM (r -0.61, p = 0.04) were observed. These results suggest that higher FNDC5/irisin levels in obese middle-aged men are related to a better metabolic profile and lower risk of T2DM development and serum LPS, a potential inducer of insulin resistance.

In Uganda, men who have sex with men (MSM) are at high risk for HIV. Between May 2008 and February 2009 in Kampala, Uganda, we used respondent driven sampling (RDS) to recruit 295 MSM≥18 years who reported having had sex with another man in the preceding three months. The parent study conducted HIV and STI testing and collected demographic and HIV-related behavioral data through audio computer-assisted self-administered interviews. We conducted a nested qualitative sub-study with 16 men purposively sampled from among the survey participants based on responses to behavioral variables indicating higher risk for HIV infection. Sub-study participants were interviewed face-to-face. Domains of inquiry included sexual orientation, gender identity, condom use, stigma, discrimination, violence and health seeking behavior. Emergent themes included a description of sexual orientation/gender identity categories. All groups of men described conflicting feelings related to their sexual orientation and contextual issues that do not accept same-sex identities or behaviors and non-normative gender presentation. The emerging domains for facilitating condom use included: lack of trust in partner and fear of HIV infection. We discuss themes in the context of social and policy issues surrounding homosexuality and HIV prevention in Uganda that directly affect men's lives, risk and health-promoting behaviors.

Multiple endocrine neoplasia syndrome type 1 (MEN1), which is secondary to mutation of the MEN1 gene, is a rare autosomal-dominant disease that predisposes mutation carriers to endocrine tumors. Although genotype-phenotype studies have so far failed to identify any statistical correlations, some families harbor recurrent tumor patterns. The function of MENIN is unclear, but has been described through the discovery of its interacting partners. Mutations in the interacting domains of MENIN functional partners have been shown to directly alter its regulation abilities. We report on a cohort of MEN1 patients from the Groupe d'étude des Tumeurs Endocrines. Patients with a molecular diagnosis and a clinical follow-up, totaling 262 families and 806 patients, were included. Associations between mutation type, location or interacting factors of the MENIN protein and death as well as the occurrence of MEN1-related tumors were tested using a frailty Cox model to adjust for potential heterogeneity across families. Accounting for the heterogeneity across families, the overall risk of death was significantly higher when mutations affected the JunD interacting domain (adjusted HR = 1.88: 95%-CI = 1.15-3.07). Patients had a higher risk of death from cancers of the MEN1 spectrum (HR = 2.34; 95%-CI = 1.23-4.43). This genotype-phenotype correlation study confirmed the lack of direct genotype-phenotype correlations. However, patients with mutations affecting the JunD interacting domain had a higher risk of death secondary to a MEN1 tumor and should thus be considered for surgical indications, genetic counseling and follow-up.
Is Sex with Older Male Partners Associated with Higher Sexual Risk Behavior Among Young Black MSM?
Chamberlain, Nicholas; Mena, Leandro A; Geter, Angelica; Crosby, Richard A

Participants at a sexual health clinic completed a survey with questions regarding sexual risk behavior and partner characteristics. Of 585 participants eligible for analysis, 124 reported generally having older male partners. These participants were significantly more likely to be HIV-infected (p < 0.001), have four or more sex partners as a "bottom" (p = 0.04), have concurrent partners (p = 0.01), and have partners suspected of having an sexually transmitted infection (p = 0.05) than participants without older partners. With analysis restricted to HIV- individuals, risk behaviors did not differ significantly between the groups. HIV- individuals with older partners may be at increased risk of HIV infection due to increased HIV prevalence among older sexual partners and not due to increased risk behaviors with these partners.

Individuals with glycated hemoglobin (HbA1c)-defined prediabetes (HbA1c value of 5.7-6.4%) and 1-hour plasma glucose ≥155 mg/dL during an oral glucose tolerance test have an increased risk of developing type 2 diabetes. To evaluate the degree to which HbA1c-defined prediabetes and 1-hour postload glucose ≥155 mg/dL individually and jointly associate with hepatic steatosis and related biomarkers. A cross-sectional analysis was performed on 1108 White individuals. Ambulatory care. Anthropometric and metabolic characteristics including hepatic steatosis assessed by ultrasonography. Compared with the normal group (HbA1c prediabetic and diabetic individuals exhibit higher values of fasting, 1-hour, and 2-hour postload glucose; fasting and 2-hour postload insulin; triglycerides; uric acid; homeostasis model of assessment for insulin resistance; liver insulin resistance index; liver enzymes; and inflammatory biomarkers; and lower levels of high-density lipoprotein cholesterol and IGF-1. Prediabetic and diabetic subjects have increased risk of hepatic steatosis (1.5- and 2.46-fold, respectively). Stratifying participants according to HbA1c and 1-hour postload glucose, we found that individuals with HbA1c-defined prediabetes and 1-hour postload glucose ≥155 mg/dL have significantly higher risk of hepatic steatosis as compared with individuals with HbA1c-defined prediabetes but 1-hour postload glucose prediabetes and 1-hour postload glucose ≥155 mg/dL exhibit higher values of liver enzymes; fasting, 1-hour, and 2-hour postload glucose; insulin; triglycerides; uric acid; and inflammatory biomarkers; and lower levels of high-density lipoprotein and IGF-1. These data suggest that a value of 1-hour postload glucose ≥155 mg/dL may be helpful to identify a subset of individuals within HbA1c-defined glycemic categories at higher risk of hepatic steatosis.

The intrauterine environment, including maternal nutrition status, may affect the development, formation, and mineralization of children's teeth. We assessed the relationship between self-reported maternal dietary vitamin D intake during pregnancy and the risk of dental caries among young Japanese children. This study is based on a prospective analysis of 1210 Japanese mother-child pairs. Information on maternal intake during pregnancy was collected using a validated diet history questionnaire. Data on oral examination at 36-46 months of age were obtained from the mothers, who transcribed the information from their maternal and child health handbooks to our self-administered questionnaire. Children were classified as having dental caries if one or more primary teeth had decayed or had been filled. Compared with the lowest quartile of maternal vitamin D intake during pregnancy, adjusted odds ratios (95% confidence intervals) for quartiles 2, 3, and 4 were 1.06 (0.72-1.56), 0.53 (0.34-0.81), and 0.67 (0.44-1.02), respectively (P for trend = .01). When maternal vitamin D intake was treated as a continuous variable, the adjusted odds ratio (95% confidence interval) was 0.94 (0.89-0.995). Higher maternal vitamin D intake during pregnancy may be associated with a lower risk of dental caries in children. Copyright © 2015 Elsevier Inc. All rights reserved.

Female injection drug users (IDUs) may report differences in injection behaviours that put them at greater risk for hepatitis C virus (HCV). Few studies have examined these in association with HCV incidence. Longitudinal data from a cohort of 417 HCV-uninfected IDU aged 30 or younger were analysed. Cox proportional hazards was used to model female sex as a predictor of new HCV infection. General estimating equation (GEE) analysis was used to model female sex as a predictor of HCV-associated risk behaviour prospectively. Women were significantly more likely than men to become infected with HCV during study follow-up (HR 1.4, p<0.05), and were also more likely than men to report high-risk injecting behaviours, especially in the context of sexual and injecting relationships. Sex differences in injecting behaviours appeared to explain the relationship between sex and HCV infection. Young women's riskier injection practices lead to their higher rates of HCV infection. Further study on the impact of intimate partnership on women's risk behaviour is warranted. Published by the BMJ Publishing Group Limited.

Evidence Report: Risk of Renal Stone Formation
Sibonga, Jean D.; Pietrzyk, Robert
2017-01-01
The formation of renal stones poses an in-flight health risk of high severity, not only because of the impact of renal colic on human performance but also because of complications that could potentially lead to crew evacuation, such as hematuria, infection, hydronephrosis, and sepsis. Evidence for risk factors comes from urine analyses of crewmembers, documenting changes to the urinary environment that are conducive to increased saturation of stone-forming salts, which are the driving force for nucleation and growth of a stone nidus. Further, renal stones have been documented in astronauts after return to Earth and in one cosmonaut during flight. Biochemical analysis of urine specimens has provided indication of hypercalciuria and hyperuricemia, reduced urine volumes, and increased urine saturation of calcium oxalate and calcium phosphate. A major contributor to the risk for renal stone formation is bone atrophy with increased turnover of the bone minerals. Dietary and fluid intakes also play major roles in the risk because of the influence on urine pH (more acidic) and on volume (decreased). Historically, specific assessments on urine samples from some Skylab crewmembers indicated that calcium excretion increased early in flight, notable by day 10 of flight, and almost exceeded the upper threshold for normal excretion (300mg/day in males). Other crewmember data documented reduced intake of fluid and reduced intake of potassium, phosphorus, magnesium, and citrate (an inhibitor of calcium stone formation) in the diet. Hence, data from both short-duration and long-duration missions indicate that space travel induces risk factors for renal stone formation that continue to persist after flight; this risk has been documented by reported kidney stones in crewmembers.

This study investigates contextual factors associated with treatment-seeking behaviour and higher-risk sexual conduct of men symptomatic of sexually transmitted infections (STIs) in Botswana. Data were drawn from a randomly selected, nationally representative sample of 8 222 men, aged 15-64 years, who had reported having symptoms suggestive of an STI during the previous twelve months. Higher-risk behaviour continues to sustain the HIV epidemic in Botswana. At the heart of Botswana's epidemic lies men's reluctance to seek medical treatment, engaging in unprotected sex, and having sex with multiple partners while symptomatic of an STI. The odds of engaging in unprotected sex while symptomatic of an STI were significantly higher among teenage males and males in urban households. For every year's increase in the age difference between partners there was a 28% increase in the odds of the male having had unprotected sex. Being married and having had more than one sexual partner in the last year multiplied the odds of having unprotected sex while symptomatic of an STI by three times. The longer an infected man remained with symptoms before seeking help, the more likely it was to have unprotected sex while infected and the more likely to seek treatment from a traditional healer. Notably, having sought medical treatment from hospitals, clinics and health workers, as opposed to consulting traditional healers, significantly reduced the odds of having had unprotected sex while infected with an STI by 48%. The results indicate the need to encourage men to utilise public healthcare services. The public health sector in Botswana needs to provide healthcare services that are user-friendly for men. Increasing the number of treatment sites may also contribute to preventing onward transmission of STIs. Special attention needs to be paid to boys' socialisation towards gender norms, and men are to be encouraged to play a responsible role in HIV prevention.

Given the unpaid nature of the work, informal caregiving can create a financial burden for caregivers. Little has been done to identify specific predictors of experiencing financial burden. This study investigated demographic and health factors comparing caregivers who reported having or not having financial burden. Data are derived from adult caregivers (N = 3,317) as part of the 2007 Behavioral Risk Factor Surveillance System in Hawaii, Kansas, and Washington. The adjusted odds ratios for reporting a financial burden were estimated for demographic and other risk factors. Caregivers who reported a financial burden were younger, had lower incomes, were more likely to be current smokers, have had a stroke, and rate their health as fair or poor compared to caregivers who did not report a financial burden. Caregivers who were younger (ages 18-34), resided with care recipients, spent 20-39 hours per week providing care, and reported having a disability were at a statistically significantly higher odds of reporting a financial burden. Given the current economic difficulties faced by many Americans, further insights into the perceived financial burdens experienced by informal caregivers as well as linkages to policy and programs designed to support caregivers are critical for public health professionals to address the expanding needs in states and communities.

Reactor risk reference document: Main report: Draft for comment
International Nuclear Information System (INIS)
1987-02-01
The Reactor Risk Reference Document, NUREG-1150, provides the results of major risk analyses for five different US light-water reactors (Surry, Zion, Sequoyah, Peach Bottom, and Grand Gulf) using state-of-the-art methods. The broad base of probabilistic risk information contained in this document is intended to provide a data base and insights to be used in a number of regulatory applications. It is anticipated that these regulatory actions will include implementation of the NRC Severe Accident Policy Statement, implementation of NRC safety goal policy, consideration of the NRC Backfit Rule, evaluation and possible revision of regulations or regulatory requirements for emergency preparedness, plant siting, and equipment qualification, and establishment of risks-oriented priorities for allocating agency resources. This report has been published in draft form. For the plants analyzed, this document describes the major factors related to internally initiated events that contribute to severe core damage, frequencies and related uncertainty ranges of severe core damage events, the major factors and severe accident phenomena that could lead to containment failure, the conditional probabilities and uncertainty ranges of early containment failure, the consequences and risks of severe accidents, including the sensitivity of these risks to factors such as evacuation or sheltering measures, comparisons of the risks with NRC safety goals, and cost and risk-reduction analyses of plant-specific measures that could reduce risk from severe accidents
Rocky Flats Plant Live-Fire Range Risk Analysis Report

The objective of the Live-Fire Range Risk Analysis Report (RAR) is to provide an authorization basis for operation as required by DOE 5480.16. The existing Live-Fire Range does not have a safety analysis-related authorization basis. EG&G Rocky Flats, Inc. has worked with DOE and its representatives to develop a format and content description for development of an RAR for the Live-Fire Range. Development of the RAR is closely aligned with development of the design for a baffle system to control risks from errant projectiles. DOE 5480.16 requires either an RAR or a safety analysis report (SAR) for live-fire ranges. An RAR rather than a SAR was selected in order to gain flexibility to more closely address the safety analysis and conduct of operation needs for a live-fire range in a cost-effective manner.

Full Text Available The purpose of the paper is to analyse knowledge sharing behaviour among non-academic staff of higher learning institutions. This research focuses on the mediation impact of perceived risk on trust and knowledge sharing behaviour. The research also proposes actions that can be taken by higher learning institutions to enhance trust among the staff in order to create a knowledge sharing environment at the workplace. This research applied confirmatory factor analysis and Structural Equation Modeling (SEM to evaluate the proposed measurement model and proved the research hypotheses. The findings from the research show that perceived risk plays a strong mediating role between trust and knowledge sharing behaviour among the non-academic staff of higher learning institutions. The SEM analysis also confirmed that the research model shows a good fit. This research highlights issues concerning knowledge sharing practices among non-academic staff and provides some recommendations to the managers to address these issues. The researchers agreed that more research needs to be done in this area as there are aspects that are yet to be explored. The findings of this research serve to add to the literature on knowledge sharing focussing on non-academic staff of higher learning institutions.

Menopause may be a risk factor for hearing loss, and postmenopausal hormone therapy (HT) has been proposed to slow hearing decline; however, there are no large prospective studies. We prospectively examined the independent relations between menopause and postmenopausal HT and risk of self-reported hearing loss. Prospective cohort study among 80,972 women in the Nurses' Health Study II, baseline age 27 to 44 years, followed from 1991 to 2013. Baseline and updated information was obtained from detailed validated biennial questionnaires. Cox proportional-hazards regression models were used to examine independent associations between menopausal status and postmenopausal HT and risk of hearing loss. After 1,410,928 person-years of follow-up, 18,558 cases of hearing loss were reported. There was no significant overall association between menopausal status, natural or surgical, and risk of hearing loss. Older age at natural menopause was associated with higher risk. The multivariable-adjusted relative risk of hearing loss among women who underwent natural menopause at age 50+ years compared with those aged less than 50 years was 1.10 (95% confidence interval [CI] 1.03, 1.17). Among postmenopausal women, oral HT (estrogen therapy or estrogen plus progestogen therapy) was associated with higher risk of hearing loss, and longer duration of use was associated with higher risk (P trend menopause and longer duration of postmenopausal HT are associated with higher risk of hearing loss.

The aim of this study was to assess religiosity and health risk behaviours among university students from 26 low, middle and high income countries. Using anonymous questionnaires, data were collected from 20,222 undergraduate university students (mean age 20.8, SD = 2. 8) from 27 universities in 26 countries across Asia, Africa and the Americas. Among all students, 41.1 % engaged at least once a week in organized religious activity, 35.8 % practised a non-organized religious activity daily or more than once daily, and more or less two-thirds of the students agreed to the three different statements on intrinsic of subjective religiosity. In multivariate logistic regression analysis, higher reported involvement in organized religious activity was associated with addictive, injury, sexual and oral health risk behaviour, while lower reported involvement in organized religious activity was associated with physical inactivity and oral health risk behaviour. Lower reported involvement in non-organized religious activity was associated with addictive, nutrition risk, injury, sexual and oral health risk behaviour, while higher reported involvement in non-organized religious activity was associated with physical inactivity. Finally, lower reported intrinsic religiosity was associated with addictive and sexual risk behaviour, while higher reported intrinsic religiosity was associated with nutrition risk behaviour, physical inactivity and oral health risk behaviour.

This synthesis study examined the reported use of credibility techniques in higher education evaluation articles that use qualitative methods. The sample included 118 articles published in six leading higher education evaluation journals from 2003 to 2012. Mixed methods approaches were used to identify key credibility techniques reported across the articles, document the frequency of these techniques, and describe their use and properties. Two broad sets of techniques were of interest: primary design techniques (i.e., basic), such as sampling/participant recruitment strategies, data collection methods, analytic details, and additional qualitative credibility techniques (e.g., member checking, negative case analyses, peer debriefing). The majority of evaluation articles reported use of primary techniques although there was wide variation in the amount of supporting detail; most of the articles did not describe the use of additional credibility techniques. This suggests that editors of evaluation journals should encourage the reporting of qualitative design details and authors should develop strategies yielding fuller methodological description.

Full Text Available We investigated how mothers’ parenting behaviors and personal characteristics were related to risk-taking by young children. We tested contrasting predictions from evolutionary and social role theories with the former predicting higher risk-taking by boys compared to girls and the latter predicting that mothers would influence children’s gender role development with risk-taking occurring more in children parented with higher levels of harshness (i.e., authoritarian parenting style. In our study, mothers reported their own gender roles and parenting styles as well as their children’s risk-taking and activities related to gender roles. The results were only partially consistent with the two theories, as the amount of risk-taking by sons and daughters did not differ significantly and risk-taking by daughters, but not sons, was positively related to mothers’ use of the authoritarian parenting style and the girls’ engagement in masculine activities. Risk-taking by sons was not predicted by any combination of mother-related variables. Overall, mothers who were higher in femininity used more authoritative and less authoritarian parenting styles. Theoretical implications as well as implications for predicting and reducing children’s risk-taking are discussed.

Qualitative interviews with mothers of babies at higher risk of sudden infant death syndrome (SIDS) were carried out to understand their views and decision-making process on the infant sleep environment and safe sleep messages. Twenty semi-structured interviews were conducted between February and November 2014 in deprived areas of Bristol, UK. Mothers were asked about their decision-making for the infant sleep environment and safe sleep messages including infant sleep position, co-sleeping, smoking, dummy use, feeding and disrupted routines. The interviews were transcribed, coded and thematic analysis carried out. Participants were invited based on an algorithm developed in a previous SIDS case control study that identified an increased risk of SIDS from four demographic characteristics: young maternal age, smoking during pregnancy, three or more children, and a measure of deprivation. The presence of three, or more characteristics led to being invited to take part in the qualitative study. Factors influencing mothers' adherence to the safe sleep messages included previous experience and the credibility of the advice given. They described disrupted routines that led to risky scenarios with a belief that occasional risks were acceptable. Where circumstances made following the advice more difficult they found alternative strategies to reduce the risk, including the use of movement monitors, regular checking and a belief that lighter maternal sleep in the presence of a baby was protective. Safer sleep messages should be tailored to fit with the lived realities of mothers, especially those at higher risk. The traditional list of 'do's' and 'don'ts' was not well accepted by this group. Interventions that seek to influence this higher-risk group should acknowledge mothers' own protective instincts and consider their beliefs and understanding behind the safer sleep messages if they are to be effective and encourage this group to change.

A cross-sectional study was developed to evaluate suicide risk and associated factors in HIV/AIDS patients at a regional reference center for the treatment of HIV/AIDS in southern Brazil. We assessed 211 patients in regard to suicide risk, clinical and sociodemographic characteristics, drug use, depression, and anxiety. Suicide risk was assessed with Mini International Neuropsychiatric Interview, Module C. Multivariate analysis was performed using Poisson regression. Of the total sample, 34.1% were at risk of suicide. In the multivariate analysis, the following variables were independently associated with suicide risk: female gender; age up to 47 years; unemployment; indicative of anxiety; indicative of depression; and abuse or addiction on psychoactive substances. Suicide risk is high in this population. Psychosocial factors should be included in the physical and clinical evaluation, given their strong association with suicide risk.

This study analyzes the U.S. 2006 Behavioral Risk Factor Surveillance System survey data (N=235,783) to test whether self-reported cardiovascular disease rates are higher in Appalachian coal mining counties compared to other counties after control for other risks. Dependent variables include self-reported measures of ever (1) being diagnosed with cardiovascular disease (CVD) or with a specific form of CVD including (2) stroke, (3) heart attack, or (4) angina or coronary heart disease (CHD). Independent variables included coal mining, smoking, BMI, drinking, physician supply, diabetes co-morbidity, age, race/ethnicity, education, income, and others. SUDAAN Multilog models were estimated, and odds ratios tested for coal mining effects. After control for covariates, people in Appalachian coal mining areas reported significantly higher risk of CVD (OR=1.22, 95% CI=1.14-1.30), angina or CHD (OR=1.29, 95% CI=1.19-1.39) and heart attack (OR=1.19, 95% CI=1.10-1.30). Effects were present for both men and women. Cardiovascular diseases have been linked to both air and water contamination in ways consistent with toxicants found in coal and coal processing. Future research is indicated to assess air and water quality in coal mining communities in Appalachia, with corresponding environmental programs and standards established as indicated.

Afternoon napping is a common habit in China. We used data obtained from the Dongfeng-Tongji cohort to examine if duration of habitual afternoon napping was associated with risks for impaired fasting plasma glucose (IFG) and diabetes mellitus (DM) in a Chinese elderly population. A total of 27,009 participants underwent a physical examination, laboratory tests, and face-to-face interview. They were categorized into four groups according to nap duration (no napping, or =90 min). Logistic regression models were used to examine the odds ratios (ORs) of napping duration with IFG and DM. Of the participants, 18,515 (68.6%) reported regularly taking afternoon naps. Those with longer nap duration had considerably higher prevalence of IFG and DM. Napping duration was associated in a dose-dependent manner with IFG and DM (Pnap duration (>60 min; all Pnap duration (>30 min) was associated with increased risk for DM; however, this finding was not significant in the group with a nap duration of 60-90 min. Longer habitual afternoon napping was associated with a moderate increase for DM risk, independent of several covariates. This finding suggests that longer nap duration may represent a novel risk factor for DM and higher blood glucose levels. Copyright © 2013. Published by Elsevier B.V.

Full Text Available Design. The social, cultural, and economic context can be an important variable in the perception and adoption of risk behaviors in adolescents. Objective. The purpose of this study was to identify the prevalence of simultaneous health risk behaviors and associated socioeconomic factors in adolescents living in the metropolitan region of Aracaju, State of Sergipe, Brazil. Methods. The sample consisted of 2,207 high school students aged 13–18 years. The risk behaviors measured were “low levels of physical activity,” “excessive daily TV time,” “high consumption of alcoholic beverages on a single occasion,” “involvement in fights,” “smoking cigarettes,” “carrying firearms,” and “marijuana consumption.” Information was obtained through self-administered questionnaire. Results. Considering the results, it was observed that female adolescents and those aged up to 16 years were less likely to have two or more health risk behaviors compared to males and those aged 17 years or more, respectively. It was also found that both high- and middle-income level adolescents had higher prevalence of having two or more health risk behaviors. Conclusions. It was concluded that male adolescents older than 16 years with better socioeconomic level were more exposed to the simultaneous presence of several health risk behaviors.

In support of the Nuclear Regulatory Commission's (NRC's) assessment of the risk from severe accidents at commercial nuclear power plants in the US report in NUREG-1150, the Severe Accident Risk Reduction Program (SARRP) has completed a revised calculation of the risk to the general public from severe accidents at the Grand Gulf Nuclear Station, Unit 1. This power plant, located in Port Gibson, Mississippi, is operated by the System Energy Resources, Inc. (SERI). The emphasis in this risk analysis was not on determining a ''so-called'' point estimate of risk. Rather, it was to determine the distribution of risk, and to discover the uncertainties that account for the breadth of this distribution. Off-site risk initiated by events internal to the power plant was assessed. 42 refs., 51 figs., 52 tabs

Full Text Available Given increasing pressures upon biodiversity, identification of species’ traits related to elevated extinction risk is useful for more efficient allocation of limited resources for nature conservation. Despite its need, such a global analysis was lacking in the case of birds. Therefore, we performed this exercise for avian sister species using information about their global extinction risk from IUCN Red List. We focused on 113 pairs of sister species, each containing a threatened and an unthreatened species to factor out the effects of common evolutionary history on the revealed relationship. We collected data on five traits with expected relationships to species’ extinction risk based on previous studies performed at regional or national levels: breeding habitat (recognizing forest, grassland, wetland and oceanic species, latitudinal range position (temperate and tropics species, migration strategy (migratory and resident species, diet (carnivorous, insectivorous, herbivorous and omnivorous species and body mass. We related the extinction risk using IUCN threat level categories to species’ traits using generalised linear mixed effects models expecting lower risk for forest, temperate, omnivorous and smaller-bodied species. Our expectation was confirmed only in the case of latitudinal range position, as we revealed higher threat level for tropical than for temperate species. This relationship was robust to different methods of threat level expression and cannot be explained by a simple association of high bird species richness with the tropical zone. Instead, it seems that tropical species are more threatened because of their intrinsic characteristics such as slow life histories, adaptations to stable environments and small geographic ranges. These characteristics are obviously disadvantageous in conditions of current human-induced environmental perturbations. Moreover, given the absence of habitat effects, our study indicates that such

Full Text Available Background: The Domain-Specific Risk Taking scale (DOSPERT has been used to measure risk perceptions and attitudes in several nations and cultures. Takahashi translated DOSPERT to Japanese but DOSPERT responses from Japan have never been reported. Butler et al. (2012 developed an additional medical risk domain subscale to be added to DOSPERT to form DOSPERT+M. Objective: To describe the translation of the medical risk domain subscale to Japanese and to characterize domain-specific risk attitudes in Tokyo. Methods: Members of a probability-weighted online panel representative of the Tokyo metro area were randomized to complete pairs of DOSPERT+M tasks (risk attitude, risk perception, benefit perception. We explored relationships among domains through correlational and factor analysis; we tested the hypothesis that the medical risk domain and DOSPERT's health/safety domains were uncorrelated. Participants: One hundred eighty panelists. Results: Six of the original DOSPERT items (two each in the ethics, health/safety, and financial domains are not useable in Japan according to the Japanese Marketing Research Association code because they ask about participation in illegal activities; we thus used abbreviated versions of those domains leaving out these items. The DOSPERT+M items generally did not cluster cleanly into the expected domains, although items within the same domain usually were intercorrelated. Participants demonstrated domain-specific conventional risk attitudes, although nearly half of those assessed were perceived-risk neutral in all domains. Unlike our recently reported findings in the U.S. population, DOSPERT+M medical domain scores were associated with health/safety domain scores, although they were often more strongly associated with scores in other domains, such as recreational activities. Conclusion: The DOSPERT (and DOSPERT+M instruments are problematic in Japan but Japanese citizens may also differ from those of other nations
Higher tier field research in ecological risk assessment: a case study

A newly developed basic procedure for site-specific ecological risk assessment in The Netherlands was followed in practice for the first time. In line with conventional Triade approaches, the procedure includes multidisciplinary parameters from environmental chemistry, toxicology and ecology to provide multiple weight of evidence. However, land use at the contaminated site and its vicinity is given more importance, and research parameters are selected in accordance to specific objectives for land use in order to test for harmful effects to underlying ecosystem services. Moreover, the approach is characterized by repetitive interactions between stakeholders and researching consultants, in particular with respect to the choice of parameters and criteria to assess the results. The approach was followed in an ecological risk assessment to test the assumptions underlying a soil management plant for a rural area in The Netherlands, called 'Krimpenerwaard'. Throughout this region some 5000 polder ditches have been filled with waste materials originating from local households, waterway sludge, industrial wastes, car shredders, and more. Several sites are severely polluted by heavy metals, cyanide, PAH or chlorinated hydrocarbons and require remediation or clean up. However, the exact distribution of these wastes over the entire region is scarcely known, and the Krimpenerwaard as a whole is treated as one case of serious soil pollution. A soil management plan was constructed by 13 stakeholding parties, aiming for a 'functional clean up' in view of land use, by means of covering 'suspected' categories of wastes with a 30-cm layer of local type soil. The ecological risk assessment aims to verify the assumptions in the soil management plan regarding the prevention of possible undesirable effects induced by the various waste materials. A tiered approach is followed, including a screening for bioavailable contaminants, a testing for general effects

Full Text Available Abstract Background Chronic hepatitis C virus infection is prevalent and often causes hepatic fibrosis, which can progress to cirrhosis and cause liver cancer or liver failure. Study of fibrosis progression often relies on imputing the time of infection, often as the reported age of first injection drug use. We sought to examine the accuracy of such imputation and implications for modeling factors that influence progression rates. Methods We analyzed cross-sectional data on hepatitis C antibody status and reported risk factor histories from two large studies, the Women's Interagency HIV Study and the Urban Health Study, using modern survival analysis methods for current status data to model past infection risk year by year. We compared fitted distributions of past infection risk to reported age of first injection drug use. Results Although injection drug use appeared to be a very strong risk factor, models for both studies showed that many subjects had considerable probability of having been infected substantially before or after their reported age of first injection drug use. Persons reporting younger age of first injection drug use were more likely to have been infected after, and persons reporting older age of first injection drug use were more likely to have been infected before. Conclusion In cross-sectional studies of fibrosis progression where date of HCV infection is estimated from risk factor histories, modern methods such as multiple imputation should be used to account for the substantial uncertainty about when infection occurred. The models presented here can provide the inputs needed by such methods. Using reported age of first injection drug use as the time of infection in studies of fibrosis progression is likely to produce a spuriously strong association of younger age of infection with slower rate of progression.

Recent research has documented that affect plays a crucial role in risk perception. When no information about numerical risk estimates is available (e.g., probability of loss or magnitude of consequences), people may rely on positive and negative affect toward perceived risk. However, determinants of affective reactions to risks are poorly understood. In a series of three experiments, we addressed the question of whether and to what degree mental imagery eliciting negative affect and stress influences risk perception. In each experiment, participants were instructed to visualize consequences of risk taking and to rate riskiness. In Experiment 1, participants who imagined negative risk consequences reported more negative affect and perceived risk as higher compared to the control condition. In Experiment 2, we found that this effect was driven by affect elicited by mental imagery rather than its vividness and intensity. In this study, imagining positive risk consequences led to lower perceived risk than visualizing negative risk consequences. Finally, we tested the hypothesis that negative affect related to higher perceived risk was caused by negative feelings of stress. In Experiment 3, we introduced risk-irrelevant stress to show that participants in the stress condition rated perceived risk as higher in comparison to the control condition. This experiment showed that higher ratings of perceived risk were influenced by psychological stress. Taken together, our results demonstrate that affect-laden mental imagery dramatically changes risk perception through negative affect (i.e., psychological stress).

In 30 states, women who have had screening mammography are informed of their breast density on the basis of Breast Imaging Reporting and Data System (BI-RADS) density categories estimated subjectively by radiologists. Variation in these clinical categories across and within radiologists has led to discussion about whether automated BI-RADS density should be reported instead. To determine whether breast cancer risk and detection are similar for automated and clinical BI-RADS density measures. Case-control. San Francisco Mammography Registry and Mayo Clinic. 1609 women with screen-detected cancer, 351 women with interval invasive cancer, and 4409 matched control participants. Automated and clinical BI-RADS density assessed on digital mammography at 2 time points from September 2006 to October 2014, interval and screen-detected breast cancer risk, and mammography sensitivity. Of women whose breast density was categorized by automated BI-RADS more than 6 months to 5 years before diagnosis, those with extremely dense breasts had a 5.65-fold higher interval cancer risk (95% CI, 3.33 to 9.60) and a 1.43-fold higher screen-detected risk (CI, 1.14 to 1.79) than those with scattered fibroglandular densities. Associations of interval and screen-detected cancer with clinical BI-RADS density were similar to those with automated BI-RADS density, regardless of whether density was measured more than 6 months to less than 2 years or 2 to 5 years before diagnosis.

Our main objective was to raise awareness of the areas that need improvements in the reporting of genetic risk prediction articles for future publications, based on the Genetic RIsk Prediction Studies (GRIPS) statement. We evaluated studies that developed or validated a prediction model based on multiple DNA variants, using empirical data, and were published in 2010. A data extraction form based on the 25 items of the GRIPS statement was created and piloted. Forty-two studies met our inclusion criteria. Overall, more than half of the evaluated items (34 of 62) were reported in at least 85% of included articles. Seventy-seven percentage of the articles were identified as genetic risk prediction studies through title assessment, but only 31% used the keywords recommended by GRIPS in the title or abstract. Seventy-four percentage mentioned which allele was the risk variant. Overall, only 10% of the articles reported all essential items needed to perform external validation of the risk model. Completeness of reporting in genetic risk prediction studies is adequate for general elements of study design but is suboptimal for several aspects that characterize genetic risk prediction studies such as description of the model construction. Improvements in the transparency of reporting of these aspects would facilitate the identification, replication, and application of genetic risk prediction models. Copyright © 2014 Elsevier Inc.

Full Text Available BACKGROUND: There is a proposed link between dietary zinc intake and atherosclerosis, but this relationship remains unclear. Phytate may contribute to this relationship by influencing zinc bioavailability. OBJECTIVE: The aim of this study is to examine the relationship between zinc bioavailability and subclinical atherosclerosis in healthy Korean adults. MATERIALS AND METHODS: The present cross-sectional analysis used baseline data from the Korean multi-Rural Communities Cohort Study (MRCohort, which is a part of The Korean Genome Epidemiology Study (KoGES. A total of 5,532 subjects (2,116 men and 3,416 women aged 40 years and older were recruited from rural communities in South Korea between 2005 and 2010. Phytate:zinc molar ratio, estimated from a food-based food frequency questionnaire (FFQ of 106 food items, was used to determine zinc bioavailability, and carotid intima media thickness (cIMT and pulse wave velocity (PWV were measured to calculate the subclinical atherosclerotic index. RESULTS: We found that phytate:zinc molar ratio is positively related to cIMT in men. A higher phytate:zinc molar ratio was significantly related to an increased risk of atherosclerosis in men, defined as the 80(th percentile value of cIMT (5(th vs. 1(st quintile, OR = 2.11, 95% CI 1.42-3.15, P for trend = 0.0009, and especially in elderly men (5(th vs. 1(st quintile, OR = 2.58, 95% CI 1.52-4.37, P for trend = 0.0021. We found a positive relationship between phytate:zinc molar ratio and atherosclerosis risk among women aged 65 years or younger. Phytate:zinc molar ratio was not found to be related to PWV. CONCLUSIONS: Lower zinc bioavailability may be related to higher atherosclerosis risk.

Whether self-reported daytime napping is an independent predictor of cardiovascular or all-cause mortality remains unclear. The aim of this study was to investigate self-reported daytime napping and risk of cardiovascular or all-cause mortality by conducting a meta-analysis. A computerized literature search of PubMed, Embase, and Cochrane Library was conducted up to May 2014. Only prospective studies reporting risk ratio (RR) and corresponding 95% confidence intervals (CI) of cardiovascular or all-cause mortality with respect to baseline self-reported daytime napping were included. Seven studies with 98,163 subjects were included. Self-reported daytime napping was associated with a greater risk of all-cause mortality (RR 1.15; 95% CI 1.07-1.24) compared with non-nappers. Risk of all-cause mortality appeared to be more pronounced among persons with nap duration >60 min (RR 1.15; 95% CI 1.04-1.27) than persons with nap duration napping is a mild but statistically significant predictor for all-cause mortality, but not for cardiovascular mortality. However, whether the risk is attributable to excessive sleep duration or napping alone remains controversial. More prospective studies stratified by sleep duration, napping periods, or age are needed.

To test the hypothesis that toddlers at highest risk for behavioral problems from the most economically vulnerable families will benefit most from maternal talk about emotions. This study included 89 toddlers and mothers from low-income families. Behavioral problems were rated at 2 time points by masters-level trained Early Head Start home visiting specialists. Maternal emotion talk was coded from a wordless book-sharing task. Coding focused on mothers' emotion bridging, which included labeling emotions, explaining the context of emotions, noting the behavioral cues of emotions, and linking emotions to toddlers' own experiences. Maternal demographic risk reflected a composite score of 5 risk factors. A significant 3-way interaction between Time 1 toddler behavior problems, maternal emotion talk, and maternal demographic risk (p = .001) and examination of slope difference tests revealed that when maternal demographic risk was greater, more maternal emotion talk buffered associations between earlier and later behavior problems. Greater demographic risk and lower maternal emotion talk intensified Time 1 behavior problems as a predictor of Time 2 behavior problems. The model explained 54% of the variance in toddlers' Time 2 behavior problems. Analyses controlled for maternal warmth to better examine the unique contributions of emotion bridging to toddlers' behaviors. Toddlers at highest risk, those with more early behavioral problems from higher demographic-risk families, benefit the most from mothers' emotion talk. Informing parents about the use of emotion talk may be a cost-effective, simple strategy to support at-risk toddlers' social-emotional development and reduce behavioral problems.

Full Text Available Abstract Background Mixed evidence exists with respect to the association between household food insecurity (HFIS and obesity in low-to-middle income countries (LMICs, particularly among women. This study aimed to measure socioeconomic correlates of HFIS and explores its association with dietary intake and odds of obesity among mothers in Lebanon, a middle-income country undergoing nutrition transition. Methods A cross-sectional study was conducted among a representative sample of households (n = 378 in Beirut, Lebanon. Surveys were completed with mothers of children <18 years. HFIS was measured using a locally-validated, Arabic-translated Household Food Insecurity Access Scale (HFIAS. Dietary intake was assessed using the multiple pass 24-h recall method. Associations between HFIS (food vs food insecure and socio-demographic characteristics were reported using crude and adjusted odds ratios. The odds of consuming <2/3rd Dietary Reference Intakes (DRIs for nutrients among mothers from food secure and food insecure households were explored. In addition, logistic regression analyses were conducted to explore the association of HFIS with obesity (BMI ≥ 30 kg/m2 and at-risk waist circumference (WC ≥ 80 cm among mothers. Results HFIS was found among 50% of study sample and was inversely associated with household income and mother’s educational level, even after adjusting for other socioeconomic variables (p < 0.01. Mothers in food insecure households reported consuming significantly less dairy products, fruits, and nuts yet more breads and sweets; and they had higher odds of consuming <2/3rd the DRI’s for key micronutrients (potassium, folate, and vitamin C compared to secure ones. Adjusting for socioeconomic correlates, food insecure mothers had 1.73 odds of obesity (95% CI: 1.02–2.92 compared to food secure mothers. Conclusions High HFIS prevalence was reported among urban Lebanese households. Mothers from food insecure

Fukushima accident discharged a large amount of radioactive materials to the air and brought about a long-term low-dose radiation exposure risk in contaminated area. In December 2011 the government working group (WG) on the risk management of low-dose radiation exposure issued the report on subjects: (1) health effects from annual radiation exposure of 20 mSv, (2) special consideration necessary for children and pregnant women and (3) proper way communicating citizens on radioactive materials and radiation doses in relation to health risks from low-dose radiation exposure. This article recommended making radiation protection strategies based on discussions among experts, government and citizens in consideration of “uncertainty” of scientific knowledge, and it criticized the WG's report mainly in the following respects. 1) The report mixed evacuation order level and ICRP's reference level in its discussion on “20 mSv”. 2) It was over-optimistic and frequently misleading on health risks of low-dose radiation. For example, it sometimes discussed the risks employing data and knowledge against recommendations of international authorities like UNSCEAR and ICRP. 3) It regarded Fukushima residents’ anxieties and stresses to be controlled as the only source of health risks. This attitude offered a counterpoint to UNSCEAR's deliberate attitude to “radiophobia”. 4) Against the spirit of ICRP Publ.111, only experts of WG made decisions about radiation protection in the absence of stakeholders. As its result, 5) risk communication recommended in the report was not interactive, in fact, based on “deficit model” of science communication. (author)

Full Text Available Ischemic stroke (IS is a multifactorial disorder caused by both genetic and environmental factors. The combined effects of multiple susceptibility genes might result in a higher risk for IS than a single gene. Therefore, we investigated whether interactions among multiple susceptibility genes were associated with an increased risk of IS by evaluating gene polymorphisms identified in previous meta-analyses, including methylenetetrahydrofolate reductase (MTHFR C677T, beta fibrinogen (FGB, β-FG A455G and T148C, apolipoprotein E (APOE ε2-4, angiotensin-converting enzyme (ACE insertion/deletion (I/D, and endothelial nitric oxide synthase (eNOS G894T. In order to examine these interactions, 712 patients with IS and 774 controls in a Chinese Han population were genotyped using the SNaPshot method, and multifactor dimensionality reduction analysis was used to detect potential interactions among the candidate genes. The results of this study found that ACE I/D and β-FG T148C were significant synergistic contributors to IS. In particular, the ACE DD + β-FG 148CC, ACE DD + β-FG 148CT, and ACE ID + β-FG 148CC genotype combinations resulted in higher risk of IS. After adjusting for potential confounding IS risk factors (age, gender, family history of IS, hypertension history and history of diabetes mellitus using a logistic analysis, a significant correlation between the genotype combinations and IS patients persisted (overall stroke: adjusted odds ratio [OR] = 1.57, 95% confidence interval [CI]: 1.22-2.02, P < 0.001, large artery atherosclerosis subtype: adjusted OR = 1.50, 95% CI: 1.08-2.07, P = 0.016, small-artery occlusion subtype: adjusted OR = 2.04, 95% CI: 1.43-2.91, P < 0.001. The results of this study indicate that the ACE I/D and β-FG T148C combination may result in significantly higher risk of IS in this Chinese population.
Suicide Risk Associated with Experience of Violence and Impulsivity in Alcohol Dependent Patients.
Khemiri, Lotfi; Jokinen, Jussi; Runeson, Bo; Jayaram-Lindström, Nitya
2016-01-19
Alcohol dependence (AD) and aggression-impulsivity are both associated with increased suicide risk. There is a need to evaluate clinical tools in order to improve suicide risk assessment of AD patients. The present study consisted of 95 individuals with a diagnosis of AD, consecutively admitted for addiction treatment, compared with 95 healthy controls. Suicidal risk was assessed together with exposure of violence and impulsivity. AD patients reported significantly higher rates of exposure to violence in childhood, as measured by the Karolinska Interpersonal Violence Scale (KIVS), compared to HC. Within the AD group, individuals with history of suicidal ideation and suicidal behavior reported higher levels of violence experience compared to AD individuals without such history. AD patients with previous suicidal ideation scored higher on self-reported impulsivity as assessed by the Barratt Impulsivity Scale (BIS). Our main finding was that experience of trauma and expression of violent behavior, coupled with increased impulsivity are associated with an elevated suicide risk in AD patients. Future longitudinal studies assessing these traits are needed to evaluate their potential role in identifying AD patients at risk of future suicide.

Diabetes mellitus is an emerging epidemic in the Arab world. Although high diabetes prevalence is documented in Israeli Arabs, information from cohort studies is scant. This is a population study, based on information derived between 2007-2011, from the electronic database of the largest health fund in Israel, among Arabs and Jews. Prevalence, 4-year-incidence and diabetes hazard ratios [HRs], adjusted for sex and the metabolic-syndrome [MetS]-components, were determined in 3 age groups (Arabs (males: 49%, age: 39.4±17.3) and 16,012 Jews (males: 50%, age: 40.5 ±17.6). The overall age and sex-adjusted diabetes prevalence rates were much higher among Arabs 18.4% (95%CI: 17.6-19.1); and 10.3% (95%CI: 9.7-10.9) among Jews. Arab females had higher prevalence rates 20.0% (95%CI: 19-21) than Arab males 16.7% (95%CI: 15.7-17.8). Annual incidence rates were also significantly higher among Arabs 2.9% (95%CI: 2.7-3.1) than among Jews 1.7% (95%CI: 1.6-1.8). This held true across all age and sex subgroups. Adjustment for body mass index [BMI] attenuated HR estimates associated with Arab ethnicity across all age subgroups, mainly in the Arabs than Jews. Males, however, did not differ by ethnicity. Arabs, mainly female, have high incidence and prevalence of diabetes. This excess risk is only partially explained by the high prevalence of obesity. Effective culturally-congruent diabetes prevention and treatment and an effective engagement partnership with the Arab community are of paramount need.

Postoperative mortality and complications after geriatric hip fracture surgery remain high despite efforts to improve perioperative care for these patients. One factor of particular interest is anesthetic technique, but prior studies on this are limited by sample selection, competing risks, and incomplete followup. (1) Among older patients undergoing surgery for hip fracture, does 90-day mortality differ depending on the type of anesthesia received? (2) Do 90-day emergency department returns and hospital readmissions differ based on anesthetic technique after geriatric hip fracture repairs? (3) Do 90-day Agency for Healthcare Research and Quality (AHRQ) outcomes differ according to anesthetic techniques used during hip fracture surgery? We conducted a retrospective study on geriatric patients (65 years or older) with hip fractures between 2009 and 2014 using the Kaiser Permanente Hip Fracture Registry. A total of 1995 (11%) of the surgically treated patients with hip fracture were excluded as a result of missing anesthesia information. The final study sample consisted of 16,695 patients. Of these, 2027 (12%) died and 98 (< 1%) terminated membership during followup, which were handled as competing events and censoring events, respectively. Ninety-day mortality, emergency department returns, hospital readmission, deep vein thrombosis (DVT) or pulmonary embolism (PE), myocardial infarction (MI), and pneumonia were evaluated using multivariable competing risk proportional subdistribution hazard regression according to type of anesthesia technique: general anesthesia, regional anesthesia, or conversion from regional to general. Of the 16,695 patients, 58% (N = 9629) received general anesthesia, 40% (N = 6597) received regional anesthesia, and 2.8% (N = 469) patients were converted from regional to general. Compared with regional anesthesia, patients treated with general anesthesia had a higher likelihood of overall 90-day mortality (hazard ratio [HR], 1.22; 95

Although surfers have high incidental exposure to marine waters, no studies have investigated if surfer risk behaviors (such as surfing during advisories, near an outfall, during a rain event, or use of personal protective equipment) increase or decrease the risk of acquiring waterborne illnesses. We used a web-based survey to assess the association between risk-based behaviors and self-reported illnesses among Pacific Northwest surfers. Commonly reported illnesses include: ear infection or discharge (38%), sore throat or a cough (28%), diarrhea (16%), fever (10.5%), and vomiting (7%). Surfing often during rain events was associated with an increased likelihood of diarrhea (OR = 2.7; 95% CI: 1.4-5.47), sore throat (OR = 1.26; 95% CI: 1.01-2.05), and ear infection (OR = 1.39; 95% CI: 1.01-2.32). Surfing during a health advisory was associated with increased likelihood of diarrhea (OR = 1.94; 95% CI: 1.03-4.64) and sore throat (OR = 2.32; 95% CI: 1.23-4.40). Other behaviors associated with increased illnesses include body surfing, surfing near an outfall, frequency of surfing, and use of ear plugs. Approximately 40% of surfers were unaware if they had surfed during an active health advisory and 29% knowingly surfed during advisories, suggesting the need to engage this population about potential harm and behaviors that may increase health risk.

Development of a brief parent-report risk index for children following parental divorce.
Tein, Jenn-Yun; Sandler, Irwin N; Braver, Sanford L; Wolchik, Sharlene A
2013-12-01
This article reports on the development of a brief 15-item parent-report risk index (Child Risk Index for Divorced or Separated Families; CRI-DS) to predict problem outcomes of children who have experienced parental divorce. A series of analyses using 3 data sets were conducted that identified and cross-validated a parsimonious set of items representing parent report of child behavior problems and family level risk and protective factors, each of which contributed to the predictive accuracy of the index. The index predicted child behavior outcomes and substance abuse problems up to 6 years later. The index has acceptable levels of sensitivity and specificity as a screening measure to predict problem outcomes up to 1 year later. The use of the index to identify the need for preventive services is discussed, along with limitations of the study.

This study analyzes the U.S. 2006 Behavioral Risk Factor Surveillance System survey data (N = 235,783) to test whether self-reported cardiovascular disease rates are higher in Appalachian coal mining counties compared to other counties after control for other risks. Dependent variables include self-reported measures of ever (1) being diagnosed with cardiovascular disease (CVD) or with a specific form of CVD including (2) stroke, (3) heart attack, or (4) angina or coronary heart disease (CHD). Independent variables included coal mining, smoking, BMI, drinking, physician supply, diabetes co-morbidity, age, race/ethnicity, education, income, and others. SUDAAN Multilog models were estimated, and odds ratios tested for coal mining effects. After control for covariates, people in Appalachian coal mining areas reported significantly higher risk of CVD (OR = 1.22, 95% CI = 1.14-1.30), angina or CHO (OR = 1.29, 95% C1 = 1.19-1.39) and heart attack (OR = 1.19, 95% C1 = 1.10-1.30). Effects were present for both men and women. Cardiovascular diseases have been linked to both air and water contamination in ways consistent with toxicants found in coal and coal processing. Future research is indicated to assess air and water quality in coal mining communities in Appalachia, with corresponding environmental programs and standards established as indicated.

The outcome of myelodysplastic syndrome (MDS) patients with uniformly higher-risk disease treated with azacitidine (AZA) in the 'real-world' remains largely unknown. We evaluated 1101 consecutive higher-risk MDS patients (International Prognostic Scoring System intermediate-2/high) and low-blast count acute myeloid leukaemia (AML; 21-30% blasts) patients treated in Ontario, Canada. By dosing schedule, 24·7% received AZA for seven consecutive days, 12·4% for six consecutive days and 62·9% by 5-2-2. Overall, median number of cycles was 6 (range 1-67) and 8 (range 6-14) when restricted to the 692 (63%) patients who received at least 4 cycles. The actuarial median survival was 11·6 months [95% confidence interval (CI) 10·7-12·4) for the entire cohort and 18·0 months (landmark analysis; 95% CI 16·6-19·1 months) for those receiving at least 4 cycles. There was no difference in overall survival (OS) between the 3 dosing schedules (P = 0·87). In our large 'real-world' evaluation of AZA in higher-risk MDS/low-blast count AML, we demonstrated a lower than expected OS. Reassuringly, survival did not differ by dosing schedules. The OS was higher in the 2/3 of patients who received at least 4 cycles of treatment, reinforcing the necessity of sustained administration until therapeutic benefits are realised. This represents the largest 'real-world' evaluation of AZA in higher-risk MDS/low-blast count AML. © 2018 John Wiley & Sons Ltd.

There is conflicting literature regarding the association between anaemia and its severity and maternal and perinatal outcomes. Methods This is a retrospective case-control study conducted at Kassala hospital, eastern Sudan. Medical files of pregnant women with severe anaemia (haemoglobin (Hb 11 g/dl, n = 303. Logistic regression analysis was performed separately for each of the outcome measures: preeclampsia, eclampsia, preterm birth, low birth weight (LBW and stillbirth. Results There were 9578 deliveries at Kassala hospital, 4012 (41.8% women had anaemia and 303 (3.2% had severe anaemia. The corrected risk for preeclampsia increased only in severe anaemia (OR = 3.6, 95% CI: 1.4-9.1, P = 0.007. Compared with women with no anaemia, the risk of LBW was 2.5 times higher in women with mild/moderate anaemia (95% CI: 1.1-5.7, and 8.0 times higher in women with severe anaemia (95% CI: 3.8-16.0. The risk of preterm delivery increased significantly with the severity of anaemia (OR = 3.2 for women with mild/moderate anaemia and OR = 6.6 for women with severe anaemia, compared with women with no anaemia. The corrected risk for stillbirth increased only in severe anaemia (OR = 4.3, 95% CI: 1.9-9.1, P Conclusions The greater the severity of the anaemia during pregnancy, the greater the risk of preeclampsia, preterm delivery, LBW and stillbirth. Preventive measures should be undertaken to decrease the prevalence of anaemia in pregnancy.

The role of social desirability bias (SDB) in self-reported HIV risk behaviors continues to be problematic. This study examined whether SDB was associated with self-reported, via audio computer assisted self-interviewing, sexual risk behaviors among people who use drugs. The present study was conducted among 559 participants who reported having a recent sexual partner at their 6-month visit of a longitudinal study. Robust Poisson regression was used to model the association between SDB and five risk behaviors. Analyses were stratified by gender and partner type. Higher scores of SDB were associated with decreased reporting of selling sex and having more than one sexual partner. Higher SDB scores were associated with increased reporting of always using condoms during oral, vaginal, and anal sex. Gender-specific differences were observed. The inclusion of a measure of SDB in data collection, along with other strategies, can be used to both identify and reduce self-report biases.

The relationship between glycemic control and adverse outcomes found in a population with diabetes has seldom been evaluated in patients with type 2 diabetes. We explored the association between hemoglobin A1c (HbA1c) and hospitalization risks within one-year and eight-year follow-up periods. We conducted a retrospective cohort study on 57,061 patients with type 2 diabetes from National Diabetes Case Management Program during 2002-2004 in Taiwan. HbA1c at baseline and in-hospital mortality, all-cause and cause-specific hospitalization over one year and eight years were analyzed. After multivariate adjustment, one-year risk was higher for cases with HbA1c level risk of hypoglycemia hospitalization (0.81, 95% CI: 0.74-0.88). For eight-year risk, subjects with HbA1c level risks of all-cause and diabetes-related hospitalization (1.04, 1.03-1.05, and 1.15, 1.14-1.17, respectively). Higher HbA1c level correlated with lower one-year risk due to hypoglycemia hospitalization but increased one-year and eight-year risks due to all-cause and diabetes-specific hospitalization among Chinese people with type 2 diabetes in Taiwan. Future study must ascertain how to meet HbA1c targets and improve outcome without risk to this population. Copyright © 2015 Elsevier Inc. All rights reserved.

Full Text Available Health care workers (HCW are at a risk of occupational acquisition of Human Immunodeficiency Virus (HIV infection, primarily due to accidental exposure to infected blood and body fluids. In our general public hospital, over a period of one year (June 2000 - 2001 a total number of 38 self reported incidences of needlestick injuries and other exposures to patient′s blood and body fluids were reported by HCWs. A greater incidence of occupational exposure was seen in surgery residents as compared to medicine residents. Till date, i.e. in one and a half-year follow up period, no seroconversion was seen in any of the reported accidental injury cases. This data emphasizes, that needle stick injuries present the single greatest risk to medical personnel and the importance of increased awareness and training in universal safety precautions (USP, for prevention of nosocomial infection.

Risk aversion is a potential unintended consequence of health care public reporting. In Part 1 of this review, four possible consequences of this phenomenon are discussed, including the denial of interventions to some high-risk patients, stifling of innovation, appropriate avoidance of futile interventions, and better matching of high-risk patients to more capable providers. We also summarize relevant observational clinical reports and survey results from cardiovascular medicine and surgery, the two specialties from which almost all risk aversion observations have been derived. Although these demonstrate that risk aversion does occur, the empirical data are much more consistent and compelling for interventional cardiology than for cardiac surgery.

The Eqo is a body scanner which allows images of the whole body to be obtained for safety purposes, without any exposure to ionising radiations, in a reliable and non-intrusive way in comparison with pat-down searching. Its technology is based on the use of so-called 'millimetre' waves. This expertise report is an answer to a public body request for an assessment of health risks related to the use of such a device. The authors first present the context of this investigation, and the Eqo gantry (operation, physical parameters, obtained image, control capacity, gantry usage). They report the assessment of electromagnetic field levels emitted by the Eqo gantry (measurement conditions, measurements), and the assessment of exposure to millimetre waves in relationship with the use of the Eqo gantry as far as passengers, airport workers and flight crews, operators, and testers are concerned. After a presentation of the potential health and biological effects of waves with a frequency higher than 1 GHz, the authors also report an assessment of health risks related to the use of Eqo (depth of penetration of waves into the body, issue of potential thermal and non thermal effects). Some recommendations are made

Using negative binomial and multi-level Poisson models, the authors determined the statistical significance of agricultural and socio-economic risk factors for rates of reported disease associated with Escherichia coli O157 in census subdivisions (CSDs) in Alberta, Canada, 2000-2002. Variables relating to population stability, aboriginal composition of the CSDs, and the economic relationship between CSDs and urban centres were significant risk factors. The percentage of individuals living in low-income households was not a statistically significant risk factor for rates of disease. The statistical significance of cattle density, recorded at a higher geographical level, depended on the method used to correct for overdispersion, the number of levels included in the multi-level models, and the choice of using all reported cases or only sporadic cases. Our results highlight the importance of local socio-economic risk factors in determining rates of disease associated with E. coli O157, but their relationship with individual risk factors requires further evaluation.

The purpose of the NCRP report no. 43 was to determine what influence the epidemiological and experimental radiobiological reports of the past several years should have on current NCRP radiation exposure standards. The position of the NCRP is that the lowest practicable radiation level below the recommended dose limits is the fundamental basis for establishing radiation protection standards, and on the assumption that the most important health hazards do not have a dose threshold. The BEIR report states that societal needs can be met with far lower average exposures and risks than permitted by the current Radiation Protection Guide of 170 millirems per yr, and that the current Guide is unnecessarily high. A review is given of the recent history of radiation protection standards and a discussion is given of similarities and differences between the BEIR and UNSCEAR reports

This nationwide population-based cohort study evaluated the effect of nonapnea sleep disorders (NSDs) on the subsequent development of a migraine. We identified 46,777 patients aged 20 years and older who were diagnosed with an NSD (ICD-9-CM: 307.4 or 780.5) and without coding for apnea-sleep disorders (ICD-9-CM: 780.51, 780.53, or 780.57) between 2000 and 2002 as the sleep disorder (SD) cohort. A comparison cohort of 93,552 people was enrolled. We calculated the adjusted hazard ratio (aHR) for developing a migraine (ICD-9-CM: 346) after adjusting for age, sex, comorbidity, and drug use. A Kaplan-Meier analysis was used to measure the cumulative incidence of a migraine between 2 curves until the end of 2011. The cumulative incidence of a migraine was significantly higher in the SD cohort. The aHR for developing a migraine in the SD cohort was 3.52 (95% CI=3.28-3.79). The risk of developing a migraine with an NSD was higher in men (aHR=4.31) than in women (aHR=3.35). The age-stratified effect of an NSD on developing a migraine was highest among patients aged 55 years and younger. Higher risks of developing a migraine were observed among the participants without any comorbidity and without any drug treatment for their insomnia. The findings of this population-based cohort study indicate a higher risk of developing a subsequent migraine in patients with an NSD, which could be considered an independent, predisposing factor for developing subsequent a migraine in adulthood.

The possible effect of radiofrequency exposure from mobile phones on tumor risk has been studied since the late 1990s. Yet, empirical information about recall of the start of mobile phone use among adult cases and controls has never been reported. Limited knowledge about recall errors hampers interpretations of the epidemiological evidence. We used network operator data to validate the self-reported start year of mobile phone use in a case-control study of mobile phone use and acoustic neuroma risk. The answers of 96 (29%) cases and 111 (22%) controls could be included in the validation. The larger proportion of cases reflects a more complete and detailed reporting of subscription history. Misclassification was substantial, with large random errors, small systematic errors, and no significant differences between cases and controls. The average difference between self-reported and operator start year was -0.62 (95% confidence interval: -1.42, 0.17) years for cases and -0.71 (-1.50, 0.07) years for controls, standard deviations were 3.92 and 4.17 years, respectively. Agreement between self-reported and operator-recorded data categorized into short, intermediate and long-term use was moderate (kappa statistic: 0.42). Should an association exist, dilution of risk estimates and distortion of exposure-response patterns for time since first mobile phone use could result from the large random errors in self-reported start year. Retrospective collection of operator data likely leads to a selection of "good reporters", with a higher proportion of cases. Thus, differential recall cannot be entirely excluded.

Full Text Available The ability and willingness of health care workers to report for work during a pandemic are essential to pandemic response. The main contribution of this article is to examine the relationship between risk perception of personal and work activities and willingness to report for work during an influenza pandemic. Data were collected through a quantitative Web-based survey sent to health care workers on the island of Montreal. Respondents were asked about their perception of various risks to obtain index measures of risk perception. A multinomial logit model was applied for the probability estimations, and a factor analysis was conducted to compute risk perception indexes (scores. Risk perception associated with personal and work activities is a significant predictor of intended presence at work during an influenza pandemic. This means that correcting perceptual biases should be a public policy concern. These results have not been previously reported in the literature. Many organizational variables are also significant.

The US Department of Energy (USDOE) has a program of research in the environmental aspects of oil and gas extraction. This sampling project will characterize the environmental impacts associated with the discharge of naturally occurring radioactive materials (NORM), metals and organics in produced water. This report is part of a series of studies of the health and ecological risks from discharges of produced water to the Gulf of Mexico, supported by the USDOE. These assessments are being coordinated with the field study, using the collected data to perform human health and ecological risk assessments. These assessments will provide input to regulators in the development of guidelines and permits, and to industry in the development and use of appropriate discharge practices. The initial human health and ecological risk assessments consist of conservative screening analyses meant to identify potentially important contaminants, and to eliminate others from further consideration. More quantitative assessments were done for contaminants identified, in the screening analysis, as being of potential concern. Section 2 gives an overview of human health and ecological risk assessment to help put the analyses presented here in perspective. Section 3 provides the hazard assessment portion of the risk assessment, and identifies the important receptors and pathways of concern. Section 3 also outlines the approach taken to the risk assessments presented in the rest of the report. The remaining sections (4 through 9) present the human health and ecological risk assessments for discharges of produced water to open bays in Louisiana

on climate change. However, the potential importance of indirect GHG emissions due to changes in soil biological and chemical properties after fire is less well known. Increased soil mineral nitrogen (N) concentrations after fire pose a risk for increased emissions of gaseous N, but studies on the post......-fire N2O production and soil N turnover rates (mineralization, nitrification, microbial immobilization, denitrification) are still rare. We determined N2O production, rates of N turnover and pathways for N2O production from the soil of burned and unburned plots of a Macchia shrubland in central Spain...... using a 15N labelling approach. Measurements were initiated before the controlled burning and continued for up to half a year after fire. Fire markedly increased the risk of N2O emissions from soil through denitrification (N2O production rate was 3 to ≈30 times higher in burned soils compared to control...

The goal of this study was to investigate metabolic risk factors in pediatric stone formers in an emerging economy. A prospective, data collection enrolled 250 children age ammonia and oxalate in urine. All reported values were two sided and statistical significance was considered at p value ≤0.05. The mean age at diagnosis was 7.50 ± 3.56 years with a male to female ratio of 1.84:1. A family history of urolithiasis was found in 41 (16.4 %), urinary tract infection in 18 (7 %) and chronic diarrhea in 75 (30 %). Hypercalcemia was seen in 37 (14.8 %), hyperuricemia in 23 (9.2 %) and hyperphosphatemia in 6 (2.4 %). Urinary metabolic abnormalities were identified in 248 (98 %) of the cases. Hypocitraturia was found in 207 (82.8 %), hyperoxaluria in 62 (26.4 %), hyperuricosuria in 82 (32.8 %), hypercalciuria in 51 (20.4 %), hyperphosphaturia in 46 (18.4 %), hyperammonuria in 10 (4 %), hypocalciuria in 82 (32.8 %), and hypovolemia in 73 (29.2 %). Risk factors were similar between genders except higher rates of hyponatriuria, hypophosphaturia, and hypocalciuria in females. Hyperuricosuria, hyponatriuria, and hypovolemia were highest in 1-5 years (52, 49, 49 %) as compared to (18, 21, 12 %) those in 11-15 years (p < 0.001), respectively. This study shows that careful metabolic analysis can identify risk factors in 98 % of the children where appropriate metaphylaxis can be undertaken both for treatment and prevention of recurrence.

There is limited data on cigarette smoking and the risk of acute pancreatitis (AP). We evaluated the influence of cigarette smoking on AP risk and clinical presentation in a large cohort of Veteran's Administration (VA) patients. Retrospective study of VA patients from 1998 to 2007. Exclusion criteria included (1) history of chronic pancreatitis (n = 3222) or gallstones (n = 14,574) and (2) age younger than 15 years (n = 270). A 2-year washout period was used to exclude patients with pre-existing recurrent AP. The study included 484,624 patients. From 2001 to 2007, a total of 6799 (1.4%) patients had AP. Alcohol (risk ratio, 4.20) and smoking (risk ratio, 1.78) were independent significant risk factors of AP on multiple regression analysis. Smoking increased the risk of AP in both nonalcoholics (0.57% vs 1.1%) and alcoholics (2.6% vs 4.1%). Smoking was associated with younger mean age at first episode of AP and higher likelihood of recurrent AP (≥4 episodes) in both nonalcoholics and alcoholics. The interval between recurrent episodes was not altered by alcohol or smoking. In a large cohort of VA patients, smoking is an independent risk factor for AP and augmented the effect of alcohol on the risk, age of onset, and recurrence of AP.

On 6 September 2014, the accidental release of 10(13) infectious wild poliovirus type 3 (WPV3) particles by a vaccine production plant in Belgium was reported. WPV3 was released into the sewage system and discharged directly to a wastewater treatment plant (WWTP) and subsequently into rivers that flowed to the Western Scheldt and the North Sea. No poliovirus was detected in samples from the WWTP, surface waters, mussels or sewage from the Netherlands. Quantitative microbial risk assessment (QMRA) showed that the infection risks resulting from swimming in Belgium waters were above 50% for several days and that the infection risk by consuming shellfish harvested in the eastern part of the Western Scheldt warranted a shellfish cooking advice. We conclude that the reported release of WPV3 has neither resulted in detectable levels of poliovirus in any of the samples nor in poliovirus circulation in the Netherlands. This QMRA showed that relevant data on water flows were not readily available and that prior assumptions on dilution factors were overestimated. A QMRA should have been performed by all vaccine production facilities before starting up large-scale culture of WPV to be able to implement effective interventions when an accident happens.

Social-interpersonal dysfunction increases disability in major depressive disorder (MDD). Here we clarified the durability of improvements in social-interpersonal functioning made during acute-phase cognitive therapy (CT), whether continuation CT (C-CT) or fluoxetine (FLX) further improved functioning, and relations of functioning with depressive symptoms and relapse/recurrence. Adult outpatients (N=241) with recurrent MDD who responded to acute-phase CT with higher risk of relapse (due to unstable or partial remission) were randomized to 8 months of C-CT, FLX, or pill placebo plus clinical management (PBO) and followed 24 additional months. We analyzed repeated measures of patients' social adjustment, interpersonal problems, dyadic adjustment, depressive symptoms, and major depressive relapse/recurrence. Large improvements in social-interpersonal functioning occurring during acute-phase CT (median d=1.4) were maintained, with many patients (median=66%) scoring in normal ranges for 32 months. Social-interpersonal functioning did not differ significantly among C-CT, FLX, and PBO arms. Beyond concurrently measured residual symptoms, deterioration in social-interpersonal functioning preceded and predicted upticks in depressive symptoms and major depressive relapse/recurrence. Results may not generalize to other patient populations, treatment protocols, or measures of social-interpersonal functioning. Mechanisms of risk connecting poorer social-interpersonal functioning with depression were not studied. Average improvements in social-interpersonal functioning among higher-risk responders to acute phase CT are durable for 32 months. After acute-phase CT, C-CT or FLX may not further improve social-interpersonal functioning. Among acute-phase CT responders, deteriorating social-interpersonal functioning provides a clear, measurable signal of risk for impending major depressive relapse/recurrence and opportunity for preemptive intervention.

Since the discovery of the ABO blood group system by Karl Landsteiner in 1901, several reports have suggested an important involvement of the ABO blood group system in the susceptibility to thrombosis. Assessing that non-O blood groups in particular A blood group confer a higher risk of venous and arterial thrombosis than group O.Epidemiologic data are typically not available for all racial and ethnics groups.The purpose of this pilot study was to identify a link between ABO blood group and ischemic disease (ID) in Africans, and to analyze whether A blood group individuals were at higher risk of ischemic disease or not. A total of 299 medical records of patients over a three-year period admitted to the cardiology and internal medicine department of military hospital of Ouakam in Senegal were reviewed. We studied data on age, gender, past history of hypertension, diabetes, smoking, sedentarism, obesity, hyperlipidemia, use of estrogen-progestin contraceptives and blood group distribution.In each blood group type, we evaluated the prevalence of ischemic and non-ischemic cardiovascular disease. The medical records were then stratified into two categories to evaluate incidence of ischemic disease: Group 1: Patients carrying blood-group A and Group 2: Patients carrying blood group non-A (O, AB and B). Of the 299 patients whose medical records were reviewed, 92 (30.8%) were carrying blood group A, 175 (58.5%) had blood group O, 13 (4.3%) had blood group B, and 19 (6.4%) had blood group AB.The diagnosis of ischemic disease (ID) was higher in patients with blood group A (61.2%) than in other blood groups, and the diagnosis of non-ischemic disease (NID) was higher in patients with blood group O (73.6%) compared to other groups. In patients with blood group B or AB compared to non-B or non-AB, respectively there was no statistically significant difference in ID incidence.Main risk factor for ID was smoking (56.5%), hypertension (18.4%) and diabetes (14.3%).In our study

Gender identity plays a potentially important role contributing to HIV risk among MSM in South Africa. Where studies have included a focus on gender identity, MSM reporting gender non-conformity have been found to have a higher risk of being HIV positive than other MSM. This article examines HIV risk among gender non-conforming MSM in a sample of 316 MSM in Cape Town, South Africa. Reporting gender non-conformity was associated with higher HIV prevalence and increased HIV risk behaviour. Gender non-conformity was also associated with a higher likelihood of being unemployed and reporting low household incomes. These findings highlight the importance of gender-identity as a factor affecting access to HIV treatment, care, and prevention in South Africa and this is an issue that needs to be addressed in interventions targeting MSM populations.

A panel of 2300 homeowners was divided into subgroups to test the effectiveness of six alternative ways of explaining the risk from naturally occurring radon gas. The research design focused on two dimensions: qualitative vs. quantitative and directive vs. evaluative. These characteristics led to 4 experimental booklets, which were compared with EPA's Citizen's Guide and a one-page fact sheet. The evaluation examined how much people learned about radon; whether they could form risk perceptions consistent with their home's measured radon level; and whether they felt they had enough information to make a decision about mitigation. The fact sheet did not perform well on any of these evaluation criteria. None of the five booklets clearly was best for all 3 evaluation criteria; the report discusses the implications for designing an effective radon-risk communication program

Full Text Available Objective: Bipolar disorder (BD is associated with significant morbidity and mortality due to comorbid general medical conditions, particularly cardiovascular disease. This study is the first report of the Brazilian Research Network in Bipolar Disorder (BRN-BD that aims to evaluate the prevalence and clinical correlates of cardiovascular risk factors among Brazilian patients with BD. Methods: A cross-sectional study of 159 patients with DSM-IV BD, 18 years or older, consecutively recruited from the Bipolar Research Program (PROMAN in São Paulo and the Bipolar Disorder Program (PROTAHBI in Porto Alegre. Clinical, demographic, anthropometric, and metabolic variables were systematically assessed. Results: High rates of smoking (27%, physical inactivity (64.9%, alcohol use disorders (20.8%, elevated fasting glucose (26.4%, diabetes (13.2%, hypertension (38.4%, hypertriglyceridemia (25.8%, low HDL-cholesterol (27.7%, general (38.4% and abdominal obesity (59.1% were found in the sample. Male patients were more likely to have alcohol use disorders, diabetes, and hypertriglyceridemia, whereas female patients showed higher prevalence of abdominal obesity. Variables such as medication use pattern, alcohol use disorder, and physical activity were associated with selected cardiovascular risk factors in the multivariable analysis. Conclusion: This report of the BRN-BD provides new data regarding prevalence rates and associated cardiovascular risk factors in Brazilian outpatients with BD. There is a need for increasing both awareness and recognition about metabolic and cardiovascular diseases in this patient population.

Full Text Available Background/objectivesThe pathologic relationship linking obesity and lipid dismetabolism with earlier onset of aging-related disorders, including cardiovascular disease (CVD and type-2 diabetes (T2D, is not fully elucidate. Chronic inflammatory state, in obese individuals, may accelerate cellular aging. However, leukocyte telomere length (LTL, the cellular biological aging indicator, is elusively linked with obesity. Recent studies indicate that sterol 27-hydroxylase (CYP27A1 is an emerging antiatherogenic enzyme, that, by converting extrahepatic cholesterol to 27-hydroxycholesterol, facilitates cholesterol removal via high-density lipoprotein-cholesterol (HDL-C. We tested the hypothesis that obese subjects who carry at least three copies of CYP27A1 low-hydroxylation (LH activity genome-wide-validated alleles (rs4674345A, rs1554622A, and rs4674338G present premature aging, as reflected in shorter LTL and higher levels of CVD/T2D risk factors, including reduced HDL-C.Subjects/methodsObese subjects from SPHERE project {n = 1,457; overweight [body mass index (BMI 25–30 kg/m2] 65.8% and severe-obese (BMI > 30 kg/m2 34.2%} were characterized for the presence from 0 to 6 LH-CYP27A1 allele copy number. Univariate and multivariable sex–age–smoking-adjusted linear-regression models were performed to compare CVD/T2D risk factors and biological aging (LTL in relation to the combined BMI-LH groups: overweight-LH: 0–2, overweight-LH: 3–6, severe-obese-LH: 0–2, and severe-obese-LH: 3–6.ResultsHigher LTL attrition was found in severe-obese than overweight individuals (p < 0.001. Multivariable model reveals that among severe-obese patients those with LH: 3–6 present higher LTL attrition than LH: 0–2 (p < 0.05. Univariate and multivariable models remarkably show that insulin resistance is higher both in overweight-LH: 3–6 vs overweight-LH: 0–2 (p < 0.001 and in severe-obese-LH: 3–6 vs severe-obese-LH: 0–2 (p
Evidence Report: Risk of Crew Adverse Health Event Due to Altered Immune Response
Crucian, Brian; Sams, Clarence F.
2013-01-01
The Risk of Crew Adverse Health Event Due to Altered Immune Response is identified by the National Aeronautics and Space Administration (NASA) Human Research Program (HRP) as a recognized risk to human health and performance in space. The HRP Program Requirements Document (PRD) defines these risks. This Evidence Report provides a summary of the evidence that has been used to identify and characterize this risk. It is known that human immune function is altered in- and post-flight, but it is unclear at present if such alterations lead to increased susceptibility to disease. Reactivation of latent viruses has been documented in crewmembers, although this reactivation has not been directly correlated with immune changes or with observed diseases. As described in this report, further research is required to better characterize the relationships between altered immune response and susceptibility to disease during and after spaceflight. This is particularly important for future deep-space exploration missions.

To compare methodological characteristics of randomized controlled trials (RCTs) published in higher vs. lower impact Core Clinical Journals. We searched MEDLINE for RCTs published in 2007 in Core Clinical Journals. We randomly sampled 1,140 study reports in a 1:1 ratio in higher (five general medicine journals with the highest total citations in 2007) and lower impact journals. Four hundred sixty-nine RCTs proved eligible: 219 in higher and 250 in lower impact journals. RCTs in higher vs. lower impact journals had larger sample sizes (median, 285 vs. 39), were more likely to receive industry funding (53% vs. 28%), declare concealment of allocation (66% vs. 36%), declare blinding of health care providers (53% vs. 41%) and outcome adjudicators (72% vs. 54%), report a patient-important primary outcome (69% vs. 50%), report subgroup analyses (64% vs. 26%), prespecify subgroup hypotheses (42% vs. 20%), and report a test for interaction (54% vs. 27%); P journals were more likely to report methodological safeguards against bias and patient-important outcomes than those published in lower impact journals. However, sufficient limitations remain such that publication in a higher impact journal does not ensure low risk of bias. Copyright © 2013 Elsevier Inc. All rights reserved.

The present study has aimed to identify the perceptions of apprentice welders about physical, chemical, biological, and physiological risk factors to which they are exposed; identify types of occupational accidents involving apprentice welders; and report the development of a socioenvironmental education intervention as a tool for risk communication for apprentice welders. A quantitative study was performed with 161 apprentice welders in Southern Brazil in 2011. Data collection was performed via structured interviews with the apprentice welders about risk perception, occupational accidents, and time experienced in welding. The data were analyzed using SPSS 19.0. The participants identified the following risk types: physical (96.9%), chemical (95%), physiological (86.3%), and biological (51.5%). In this sample, 39.7% of apprentice welders reported occupational accidents and 27.3% reported burning. The inferential analysis showed that the frequency of risk perception factors increases with the length of experience, and apprentice welders who have experienced accidents during welding activity perceive a higher amount of risk factors than those who have never experienced them. It is concluded that apprentice welders perceive risks and that they tend to relate risks with the occurrence of occupational accidents as an indicator of the dangerous nature of their activity.

A field study with follow up investigations sought to: 1. determine whether cold packs (over-the-counter symptomtic treatments), coupled with in-office education, improve antibiotic-related knowledge, attitudes and behaviors more than in-office education alone in patient populations with high percentages of Asian Americans and Hawaiian/Pacific Islanders; 2. identify possible reasons for intervention outcomes as described by physicians who participated in the field study; and 3. explore potential future directions based on a large sample survey of physicians in the field study's highly ethnic county. The intervention resulted in a pre- to post-consultation decrease in perceived need for and an increase in knowledge about antibiotic risks but had no impact on frequency of reported receipt of an antibiotic prescription. Unexpectedly, in-office education alone was more effective in increasing knowledge than in-office education plus the cold pack. In-depth interviews of field study physicians and a large scale physician survey suggest that cold pack interventions targeting patient populations with high percentages of Asian Americans and Hawaiian/Pacific Islanders may be more likely to succeed if accompanied by mass public education regarding risks and physician training regarding effective ways to talk to patients. Use of in-office education with cold packs alone may not achieve desired results. Hawaii Medical Journal Copyright 2010.

Background: Only few authors have analyzed the impact of workplace conflicts and the resulting stress on the risk of developing cardiovascular disorders. The goal of this study was to analyze the association between workplace conflicts and cardiovascular disorders in patients treated by German general practitioners. Methods: Patients with an initial documentation of a workplace conflict experience between 2005 and 2014 were identified in 699 general practitioner practices (index date). We included only those who were between the ages of 18 and 65 years, had a follow-up time of at least 180 days after the index date, and had not been diagnosed with angina pectoris, myocardial infarction, coronary heart diseases, or stroke prior to the documentation of the workplace mobbing. In total, the study population consisted of 7,374 patients who experienced conflicts and 7,374 controls for analysis. The main outcome measure was the incidence of angina pectoris, myocardial infarction, and stroke correlated with workplace conflict experiences. Results: After a maximum of five years of follow-up, 2.9% of individuals who experienced workplace conflict were affected by cardiovascular diseases, while only 1.4% were affected in the control group (p-value <0.001). Workplace conflict was associated with a 1.63-fold increase in the risk of developing cardiovascular diseases. Finally, the impact of workplace conflict was higher for myocardial infarction (OR=2.03) than for angina pectoris (OR=1.79) and stroke (OR=1.56). Conclusions: Overall, we found a significant association between workplace conflicts and cardiovascular disorders. PMID:28496397

The United Nations Framework Convention on Climate Change (UNFCCC) meeting to be held in Copenhagen in December 2009 (the 15th Conference of the Parties, COP-15) will be a critical step in developing a global response to the threat of climate change caused by human activities. The primary scientific input to those negotiations is the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), published in 2007. The IPCC report has already been instrumental in increasing both public and political awareness of the societal risks associated with unchecked emission of greenhouse gases. Since the production of the IPCC report, new knowledge has emerged that furthers understanding of the impacts of human influence on the climate and the response options and approaches that are available to tackle this complex issue. To bring this new knowledge together, the International Alliance of Research Universities organised an international scientific congress on climate change, Climate Change: Global Risks, Challenges and Decisions, which was held in Copenhagen from 10-12 March 2009. Participants came from nearly 80 different countries and contributed with more than 1400 scientific presentations. Abstracts for all of the scientific presentations made can be found at www.iop.org/EJ/volume/1755-1315/6, and a transcript of the closing plenary session can be found at environmentalresearchweb.org/cws/article/opinion/39126. This synthesis report presents an up-to-date overview of a broad range of research relevant to climate change - including fundamental climate science, the impacts of a changing climate on society and environment, and the many tools and approaches available to deal effectively with the challenge of climate change.

The prevalence of ischaemia-related symptoms is remarkably high among elite indoor volleyball players. Since the exposure to sport-specific demands may be higher in beach volleyball compared to indoor volleyball, the aim of this study was to assess the prevalence of ischaemia-related symptoms and associated risk factors among world-class beach volleyball players. Therefore, a questionnaire survey was performed among beach volleyball players active during the 2013 Grand Slam Beach Volleyball in the Netherlands. In total, 60 of the 128 beach volleyball players (47%) participated: 26 males and 34 females from 17 countries. The self-reported prevalence of cold or blue or pale digits in the dominant hand during or immediately after practice or competition was 38% (n = 23). Two risk factors were independently associated with symptoms of blue or pale digits: more than 14 years playing volleyball (odds ratio (OR) 4.42, 90% confidence interval (90% CI) 1.30-15.07) and sex (female) (OR 4.62, 90% CI 1.15-18.57). In conclusion, the prevalence of symptoms associated with digital ischaemia is high among international world-class beach volleyball players. Female sex and the length of the volleyball career were independently associated with an increased risk of ischaemia-related symptoms. The high prevalence of these seemingly innocuous symptoms and possible associated risk factors warrant regular monitoring since early detection can potentially prevent thromboembolic complications and irreversible tissue damage.

The spine is the most common site for bone metastases. Radiation therapy is a common treatment for palliation of pain and for prevention or treatment of spinal cord compression. Helical tomotherapy (HT), a new image-guided intensity modulated radiotherapy (IMRT), delivers highly conformal dose distributions and provides an impressive ability to spare adjacent organs at risk, thus increasing the local control of spinal column metastases and decreasing the potential risk of critical organs under treatment. However, there are a lot of non-target organs at risk (OARs) occupied by low dose with underestimate in this modern rotational IMRT treatment. Herein, we report a case of a pathologic compression fracture of the T9 vertebra in a 55-year-old patient with cholangiocarcinoma. The patient underwent HT at a dose of 30 Gy/10 fractions delivered to T8-T10 for symptom relief. Two weeks after the radiotherapy had been completed, the first course of chemotherapy comprising gemcitabine, fluorouracil, and leucovorin was administered. After two weeks of chemotherapy, however, the patient developed progressive dyspnea. A computed tomography scan of the chest revealed an interstitial pattern with traction bronchiectasis, diffuse ground-glass opacities, and cystic change with fibrosis. Acute radiation pneumonitis was diagnosed. Oncologists should be alert to the potential risk of radiation toxicities caused by low dose off-targets and abscopal effects even with highly conformal radiotherapy

Latent profile analysis (LPA) was used to classify 394 adolescents undergoing substance use treatment, based on past year psychiatric symptoms. Relations between profile membership and (a) self-reported childhood maltreatment experiences and (b) current sexual risk behavior were examined. LPA generated three psychiatric symptom profiles: Low-, High- Alcohol-, and High- Internalizing Symptoms profiles. Analyses identified significant associations between profile membership and childhood sexual abuse and emotional neglect ratings, as well as co-occurring sex with substance use and unprotected intercourse. Profiles with elevated psychiatric symptom scores (e.g., internalizing problems, alcohol abuse and dependence symptoms) and more severe maltreatment histories reported higher scores for behavioral risk factors for HIV/STI exposure. Heterogeneity in psychiatric symptom patterns among youth receiving substance use treatment services, and prior histories of childhood maltreatment, have significant implications for the design and delivery of HIV/STI prevention programs to this population.
Reduced cancer risk in vegetarians: an analysis of recent reports.
Lanou, Amy Joy; Svenson, Barbara
2010-12-20
This report reviews current evidence regarding the relationship between vegetarian eating patterns and cancer risk. Although plant-based diets including vegetarian and vegan diets are generally considered to be cancer protective, very few studies have directly addressed this question. Most large prospective observational studies show that vegetarian diets are at least modestly cancer protective (10%-12% reduction in overall cancer risk) although results for specific cancers are less clear. No long-term randomized clinical trials have been conducted to address this relationship. However, a broad body of evidence links specific plant foods such as fruits and vegetables, plant constituents such as fiber, antioxidants and other phytochemicals, and achieving and maintaining a healthy weight to reduced risk of cancer diagnosis and recurrence. Also, research links the consumption of meat, especially red and processed meats, to increased risk of several types of cancer. Vegetarian and vegan diets increase beneficial plant foods and plant constituents, eliminate the intake of red and processed meat, and aid in achieving and maintaining a healthy weight. The direct and indirect evidence taken together suggests that vegetarian diets are a useful strategy for reducing risk of cancer.

In environmental surveys, risk perception may be a source of bias when information on health outcomes is reported using questionnaires. Using the data from a survey carried out in the largest chipboard industrial district in Italy (Viadana, Mantova), we devised a score of health risk perception and described its determinants in an adult population. In 2006, 3697 parents of children were administered a questionnaire that included ratings on 7 environmental issues. Items dimensionality was studied by factor analysis. After testing equidistance across response options by homogeneity analysis, a risk perception score was devised by summing up item ratings. Factor analysis identified one latent factor, which we interpreted as health risk perception, that explained 65.4% of the variance of five items retained after scaling. The scale (range 0-10, mean ± SD 9.3 ± 1.9) had a good internal consistency (Cronbach's alpha 0.87). Most subjects (80.6%) expressed maximum risk perception (score = 10). Italian mothers showed significantly higher risk perception than foreign fathers. Risk perception was higher for parents of young children, and for older parents with a higher education, than for their counterparts. Actual distance to major roads was not associated with the score, while self-reported intense traffic and frequent air refreshing at home predicted higher risk perception. When investigating health effects of environmental hazards using questionnaires, care should be taken to reduce the possibility of awareness bias at the stage of study planning and data analysis. Including appropriate items in study questionnaires can be useful to derive a measure of health risk perception, which can help to identify confounding of association estimates by risk perception.

Coronary heart disease causes approximately 45% of firefighter deaths annually. Although firefighters have clinically significant cardiac risks, a paucity of research and data exists. To evaluate firefighters' cardiac risk factors as well as their motivation to resolve these risk factors. During a 3-month period, volunteer firefighters representing the 79 fire departments serving Nassau and Suffolk counties in Long Island, NY, were asked to complete a nonvalidated, 19-item questionnaire regarding their health habits, medical history, and demographics. A total of 730 surveys were returned among a potential study population of 20,590 volunteer firefighters. More than three-quarters of respondents met the criteria for being overweight or obese, and nearly 40% reported having high blood pressure, high cholesterol, or both. Most respondents expressed at least some interest in attending a fire department-sponsored health lecture and participating in a fitness program. Firefighters expressed desire to learn more about risk factor modifications and have fire departments take a more active role in helping firefighters improve their health. The effectiveness of resources and intervention programs should be assessed.

Background: The Cancer of the Prostate Risk Assessment (CAPRA) was developed to predict freedom from biochemical failure (FFBF) following radical prostatectomy (RP). Its utility following external beam radiation therapy (EBRT) has not been externally evaluated. Methods: A retrospective study of 612 patients treated with dose-escalated EBRT at University of Michigan Medical Center. Results: Compared to the derivation cohort, EBRT treated patients had higher-risk disease (28% with CAPRA of 6–10 vs. 5%, respectively). A total of 114 patients (19%) had BF with 5-year BF ranging from 7% with CAPRA 0–3 to 35% with CAPRA 7–10. For RT patients the risk of BF at 5-year was similar to 4 surgical cohorts for CAPRA scores 0–2 but lower for all CAPRA scores ⩾ 3. The difference favoring RT increased with increasing CAPRA score reaching a 27–50% absolute improved at 5-years for CAPRA scores of 6–10. On multivariate analysis each CAPRA point increased the risk of BF (p < 0.0001) while Gleason pattern 5 in the biopsy also increased BF (p = 0.01) and long-term androgen deprivation therapy (ADT) significantly reduced the risk of BF (p = 0.015). Conclusions: Compared to surgical series the risk of BF was lower with dose-escalated EBRT with the greatest difference at the highest CAPRA scores.

An evaluation of the treatment of risk and uncertainties in the IPCC reports on climate change.
Aven, Terje; Renn, Ortwin
2015-04-01
Few global threats rival global climate change in scale and potential consequence. The principal international authority assessing climate risk is the Intergovernmental Panel on Climate Change (IPCC). Through repeated assessments the IPCC has devoted considerable effort and interdisciplinary competence to articulating a common characterization of climate risk and uncertainties. We have reviewed the assessment and its foundation for the Fifth Assessment Reports published in 2013 and 2014, in particular the guidance note for lead authors of the fifth IPCC assessment report on consistent treatment of uncertainties. Our analysis shows that the work carried out by the ICPP is short of providing a theoretically and conceptually convincing foundation on the treatment of risk and uncertainties. The main reasons for our assessment are: (i) the concept of risk is given a too narrow definition (a function of consequences and probability/likelihood); and (ii) the reports lack precision in delineating their concepts and methods. The goal of this article is to contribute to improving the handling of uncertainty and risk in future IPCC studies, thereby obtaining a more theoretically substantiated characterization as well as enhanced scientific quality for risk analysis in this area. Several suggestions for how to improve the risk and uncertainty treatment are provided. © 2014 Society for Risk Analysis.
Increased risk taking in relation to chronic stress in young adults

Full Text Available Chronic stress is a public health problem that affects a significant part of the population. While the physiological damage it causes is under ongoing scrutiny, its behavioral effects have been overlooked. This is one of the first studies to examine the relation between chronic stress and decision-making, using a standard lottery paradigm. We measured learning-independent risk taking in the gain domain through binary choices between financially incentivized lotteries. We then measured self-reported chronic stress with the Trier Inventory for the Assessment of Chronic Stress (TICS. We additionally collected hair samples in a subsample of volunteers, in order to quantify chronic cortisol exposure. We discovered a significant, positive correlation between self-reported chronic stress and risk taking that is stronger for women than for men. This confirms part of the findings in acute stress research that show a connection between higher stress and increased risk taking. However, unlike the biologically-based results from acute stress research, we did not identify a significant relation between hair cortisol and behavior. In line with previous literature, we found a clear gender difference in risk taking and self-reports: women generally take less risk and report slightly higher stress levels than men. We conclude that perceived chronic stress can impact behavior in risky situations.

The prudent use of antimicrobials (AMs) should be widened in pig farming to reduce the risk of AM resistance (AMR) in human and veterinary medicine. It is therefore important to understand pig farmers' motivators and the barriers to AM usage (AMU) on their farms. The authors investigated pig farmers' self-estimated levels of AMU, their perceived benefits and risks and the need for AMs in a cross-sectional survey in Belgium, France, Germany and Sweden. The authors also compared these perceptions between the four countries and related them to pig farmers' actual AMU. The results showed that farmers who used more AMs also estimated their own usage as higher. Farmers perceived many benefits but relatively few risks of AMU in pig farming. Some significant cross-country differences in farmers' perceptions were found, but they were relatively small. After controlling for country differences and farm differences, only perceived risks had a significant association with AMU. The authors therefore conclude that in order to promote prudent AMU, it seems most promising to focus on the structural differences in pig farming and veterinary medicine (e.g. legislation, role of the veterinarian) among countries. In addition, interventions which aim at reducing AMU should increase farmers' awareness of the risks of extensive AMU. British Veterinary Association.

Abstract Background Under the current ethical and legal standards physicians are expected to breach confidentiality when a third party is at risk. However, the law has mainly focused on risk of bodily harm and there is no legal guidance on physicians’ responsibilty when it comes to risk of psychological harm to a potential targeted victim Methods This case report illustrates a clinical dilemma on duty to warn for mental health professionals. Results N/A Discussion This case report illustrates an unconventional perspective on a psychiatrist’s duty to warn: consideration of risk of psychological harm to the potential target of their patient. Psychological trauma can have a potential negative impact on victims, affecting their mental health and well being as well as their physical health. The ethicolegal dilemma discussed in this case has implications for policies related to the care of psychiatric patients.

Child maltreatment prevention programs typically identify at-risk families by screening for risk with limited consideration of how risk might vary by ethnicity. In this study, longitudinal data from mothers who participated in a randomized clinical trial of a home-visitation, child maltreatment prevention program (N = 262) were examined to determine whether risk for harsh parenting differed among mothers who identified themselves as Spanish-speaking Latinas (n = 64), English-speaking Latinas (n = 102), or non-Latina Caucasians (n = 96). The majority of the participants were first-time mothers (58.4%), and the average age of all participants was 23.55 years (SD = 6.04). At the time of their infants' births, the Spanish-speaking Latina mothers demonstrated higher SES risk, whereas the English-speaking Latina and non-Latina Caucasian mothers demonstrated higher psychosocial risk. Three years later, the English-speaking Latina and non-Latina Caucasian mothers reported harsher parenting behaviors than the Spanish-speaking Latina mothers. The need for prevention programs to consider how risk and protective factors differ by ethnic group membership when identifying at-risk mothers is discussed.

In this study, we investigated the independent and combined effects of sleep duration and afternoon napping on the risk of incident diabetes among a cohort of middle-aged and older Chinese adults. Information of sleep and napping was obtained by questionnaires during face-to-face interviews. We categorized sleep duration into napping was divided into no napping (0 min) (reference), 1-30 min, 31-60 min, 61-90 min, and > 90 min. Cox proportional hazard regression models were used. Compared with referential sleeping group, subjects sleeping ≥10 h had a 42% higher risk of developing diabetes. The HR was 1.28 for napping > 90 min when compared with no napping. These associations were more pronounced in individuals without hypertension. Combined effects of long sleep duration and afternoon napping were further identified. Individuals with both sleep duration ≥ 10 h and napping > 60 min had a 72% higher risk of incident diabetes than those with sleeping 7∼napping 0 min (all above p napping were independently and jointly associated with higher risk of incident diabetes. Key messages Sleep duration was associated with diabetes, but whether it is a real cause of incident diabetes especially in Chinese still remains to be elucidated. The association of afternoon napping and diabetes was not consistent and definite, we clarified this association in a large prospective study. Long sleep duration and afternoon napping were independently and jointly associated with higher risk of incident diabetes.

HIV testing and serostatus awareness are essential to implement biomedical strategies (treatment as prevention; oral chemoprophylaxis), and for effective serostatus-based behaviours (HIV serosorting; strategic positioning). The analysis focuses on the associations between reported sexual risks, the perceived risk for HIV infection, and HIV testing behaviour in order to identify the most relevant barriers for HIV test uptake among MSM living in Germany. MSM were recruited to a nationwide anonymous online-survey in 2013 on MSM social networking/dating sites. Questions covered testing behaviours, reasons for testing decisions, and HIV risk perception (5-point scale). Additional questions addressed arguments in favour of home/ home collection testing (HT). Using descriptive statistics and logistic regression we compared men reporting recent HIV testing (RT; previous 12 month) with men never tested (NT) in a subsample not previously diagnosed with HIV and reporting ≥2 episodes of condomless anal intercourse (CLAI) with a non-steady partner of unknown HIV serostatus in the previous 12 months. The subsample consisted of 775 RT (13 % of RT) and 396 NT (7 % of NT). The number of CLAI episodes in the last 12 months with non-steady partners of unknown HIV status did not differ significantly between the groups, but RT reported significantly higher numbers of partners (>5 AI partners: 65 vs. 44 %). While perceived risks regarding last AI were comparable between the groups, 49vs. 30 % NT were risks (67 %) and routine testing (49 %) were the most common testing reasons for RT, while the strong belief not to be infected (59 %) and various worries (41 %) and fears of testing positive (35 %) were predominant reasons of NT. Greater anonymity (aOR 3.2; 2.4-4.4), less embarrassment, (aOR 2.8; 1.9-4.1), and avoiding discussions on sexual behaviour (aOR 1.6; 1.1-2.2) were emphasized in favour of HT by NT. Perceived partner knowledge and reasons reflecting perceived gay- and

The association between specific fish intake and colorectal cancer risk remains controversial. This study aimed to examine the association between specific fish intake and colorectal cancer risk in Chinese population in a large case control study. During July 2010 to November 2014, 1189 eligible colorectal cancer cases and 1189 frequency-matched controls (age and sex) completed in-person interviews. A validated food frequency questionnaire was used to estimate dietary intake. Multivariate logistical regression models were used to estimate the odds ratio (OR) and 95% confidence interval (95% CI) after adjusting for various confounders. A strong inverse association was found between freshwater fish intake and colorectal cancer risk. Compared with the lowest quartile, the highest quartile intake showed a risk reduction of 53% (OR 0.47, 95% CI = 0.36-0.60, Ptrend colorectal cancer risk. These results indicate that higher consumption of freshwater fish, sea fish and fresh fish is associated with a lower risk of colorectal caner.

Models of risk-taking typically assume that the variability of outcomes is important in the likelihood of making a risky choice. In an animal model of the Balloon Analogue Risk Task (BART), within-session variability, or the coefficient of variability (CV), was found to be a novel predictor of behavior (Jentsch et al., 2010). Human studies have not investigated how BART performance differs when using the CV versus a traditional BART measure (e.g., number of pumps). This study sought to determine whether the CV provides a unique and valuable alternative index of risk-taking on the BART, and to determine the relationship of the CV to self-reported alcohol consumption. Young adult heavy drinkers (n = 58, 72% male, mean age 21.53) completed an assessment of drinking patterns and a modified version of the BART. Multiple regression results indicated that CV is a unique predictor of total explosions and total money earned on the BART. Higher levels of variability were associated with fewer explosions but less money earned, whereas more pumps was associated with more explosions but more money. Higher CV was also associated with lower lifetime and past 3 months peak drinking quantity, higher levels of self-efficacy to control drinking, and lower levels of drinking acceptability (i.e., injunctive norms). Total pumps was associated with higher lifetime peak drinking, lower self-efficacy to control drinking, and higher levels drinking acceptability. Overall, the CV can provide an alternative method of assessing BART performance and the association of risk-taking with drinking patterns.

Revision of risk estimates and implications for dose limits

Clarke, R.H.
1989-01-01
It has been apparent for some time that our estimates of the risks associated with exposure to ionizing radiation must be increased above those values reported by UNSCEAR in 1977 an dused by ICRP to form their present recommendations. NRPB foresaw some of these changes and introduced interim advice within the UK to restrict exposures of wordkers and members of the public to levels below the existing limits. Since that advice was given, UNSCEAR has produced a 1988 report reviewing human data to provide new estimates of risks associated with exposure at high doses and high doserates. These risk figures are up to 4 times higher than when UNSCEAR reported in 1977. In this paper, the reasons for the changes in the estimates of risk will be described and the current NRPB guidelines for risk factors for protection purposes will be presented. The implications of these new risk factors for the setting of dose limits will then be discussed. (Author). 10 refs.; 2 tabs

Few studies have addressed social motivation in prospective memory (PM). In a pilot study and two main studies, we examined whether social PM tasks possess a motivational advantage over nonsocial PM tasks. In the pilot study and Study 1, participants listed their real-life important and less important PM tasks. Independent raters categorized the PM tasks as social or nonsocial. Results from both studies showed a higher proportion of tasks rated as social when important tasks were requested than when less important tasks were requested. In Study 1, participants also reported whether they had remembered to perform each PM task. Reported performance rates were higher for tasks rated as social than for those rated as nonsocial. Finally, in Study 2, participants rated the importance of two hypothetical PM tasks, one social and one nonsocial. The social PM task was rated higher in importance. Overall, these findings suggest that social PM tasks are viewed as more important than nonsocial PM tasks and they are more likely to be performed. We propose that consideration of the social relevance of PM will lead to a more complete and ecologically valid theoretical description of PM performance.

Deep-bed methyl iodide adsorption testing has continued in Fiscal Year 2016 under the Department of Energy (DOE) Fuel Cycle Technology (FCT) Program Offgas Sigma Team to further research and advance the technical maturity of solid sorbents for capturing iodine-129 in off-gas streams during used nuclear fuel reprocessing. Adsorption testing with higher levels of NO (approximately 3,300 ppm) and NO2 (up to about 10,000 ppm) indicate that high efficiency iodine capture by silver aerogel remains possible. Maximum iodine decontamination factors (DFs, or the ratio of iodine flowrate in the sorbent bed inlet gas compared to the iodine flowrate in the outlet gas) exceeded 3,000 until bed breakthrough rapidly decreased the DF levels to as low as about 2, when the adsorption capability was near depletion. After breakthrough, nearly all of the uncaptured iodine that remains in the bed outlet gas stream is no longer in the form of the original methyl iodide. The methyl iodide molecules are cleaved in the sorbent bed, even after iodine adsorption is no longer efficient, so that uncaptured iodine is in the form of iodine species soluble in caustic scrubber solutions, and detected and reported here as diatomic I2. The mass transfer zone depths were estimated at 8 inches, somewhat deeper than the 2-5 inch range estimated for both silver aerogels and silver zeolites in prior deep-bed tests, which had lower NOx levels. The maximum iodine adsorption capacity and silver utilization for these higher NOx tests, at about 5-15% of the original sorbent mass, and about 12-35% of the total silver, respectively, were lower than for trends from prior silver aerogel and silver zeolite tests with lower NOx levels. Additional deep-bed testing and analyses are recommended to expand the database for organic iodide adsorption and increase the technical maturity if iodine adsorption processes.

In this study, we report that self-perception of fracture risk captures some aspect of fracture risk not currently measured using conventional fracture prediction tools and is associated with improved medication uptake. It suggests that adequate appreciation of fracture risk may be beneficial and lead to greater healthcare engagement and treatment. This study aimed to assess how well self-perception of fracture risk, and fracture risk as estimated by the fracture prediction tool FRAX, related to fracture incidence and uptake and persistence of anti-osteoporosis medication among women participating in the Global Longitudinal study of Osteoporosis in Women (GLOW). GLOW is an international cohort study involving 723 physician practices across 10 countries in Europe, North America and Australia. Aged ≥ 55 years, 60,393 women completed baseline questionnaires detailing medical history, including co-morbidities, fractures and self-perceived fracture risk (SPR). Annual follow-up included self-reported incident fractures and anti-osteoporosis medication (AOM) use. We calculated FRAX risk without bone mineral density measurement. Of the 39,241 women with at least 1 year of follow-up data, 2132 (5.4%) sustained an incident major osteoporotic fracture over 5 years of follow-up. Within each SPR category, risk of fracture increased as the FRAX categorisation of risk increased. In GLOW, only 11% of women with a lower baseline SPR were taking AOM at baseline, compared with 46% of women with a higher SPR. AOM use tended to increase in the years after a reported fracture. However, women with a lower SPR who were fractured still reported lower AOM rates than women with or without a fracture but had a higher SPR. These results suggest that SPR captures some aspect of fracture risk not currently measured using conventional fracture prediction tools and is also associated with improved medication uptake.

Background Primary Biliary Cirrhosis is a cholestatic liver disease characterized by immune-mediated destruction of bile ducts. Its pathogenesis is largely unknown, although complex interactions between environment and genetic predisposition are proposed. Aims Identify disease risk factors using a detailed patient questionnaire and compare study findings to 3 published reports. Methods Questionnaire data were prospectively collected from 522 cases and 616 controls of the Mayo Clinic Primary Biliary Cirrhosis Genetic Epidemiology Registry. Case and control responses were compared using logistic regression, adjusting for recruitment age, sex, and education level. Results Cases reported ever regularly smoking cigarettes more frequently than controls (P < 0.001). History of urinary tract infection (UTI) was similar between groups; however, cases reported multiple UTIs more commonly than controls (P < 0.001). Frequency of other autoimmune disease was higher in cases than controls (P < 0.001). As well, prevalence of primary biliary cirrhosis among first-degree relatives was higher in case families than control families (P < 0.001). Conclusions Our study confirms prior reported risk factors associated with disease risk. Given the potential importance of gene and environment interactions, further examination of environmental risk factors considering genetic background may provide new insight into primary biliary cirrhosis pathogenesis.

AIM: To compare anxiety symptoms in adolescents born extremely prematurely to term-born controls. METHODS: We had 96 preterm-born adolescents and 40 term-born controls from Denmark, and their mothers score the adolescents on the Revised Children Anxiety and Depression scale. We analysed group...... differences, cross-informant correlations and relative risks for elevated anxiety symptoms. RESULTS: Self-reported anxiety symptoms did not significantly differ, although the upper confidence limit (95% CI: -3.3 to 5.1) supported an odds ratio of 2 for the preterm-born participants. Mothers of the preterm......-born participants reported higher social anxiety symptoms than did mothers of controls (51.7 versus 46.8, p = 0.001). The relative risk for being above a threshold indicating distressing anxiety was small from self-reports (1.39; p = 0.60). From mother-reports, the relative risk was noticeable but not significant...

This report presents an ecological risk assessment for Waste Area Grouping (WAG) 2 based on the data collected in the Phase I remedial investigation (RI). It serves as an update to the WAG 2 screening ecological risk assessment that was performed using historic data. In addition to identifying potential ecological risks in WAG 2 that may require additional data collection, this report serves to determine whether there are ecological risks of sufficient magnitude to require a removal action or some other expedited remedial process. WAG 2 consists of White Oak Creek (WOC) and its tributaries downstream of the Oak Ridge National Laboratory (ORNL) main plant area, White Oak Lake (WOL), the White Oak Creek Embayment of the Clinch River, associated flood plains, and the associated groundwater. The WOC system drains the WOC watershed, an area of approximately 16.8 km{sup 2} that includes ORNL and associated WAGs. The WOC system has been exposed to contaminants released from ORNL and associated operations since 1943 and continues to receive contaminants from adjacent WAGs.

To examine whether socioeconomic status, as measured by educational attainment and annual household income, is associated with lifetime risk for workplace eye injury in a large US population. In analyses of data from the Behavioral Risk Factor Surveillance System (2005-2007, N = 43,510), we used logistic regression analysis and propensity score matching to assess associations between socioeconomic measures and lifetime risk for workplace eye injury among those aged ≥50 years. The lifetime prevalence of self-reported workplace eye injury was significantly higher among men (13.5%) than women (2.6%) (P workplace eye injury than those with more than a high school education. Men with an annual household income workplace eye injury than those whose income was >$50,000 (adjusted OR = 1.44, 95% CI: 1.07-1.95). After adjusting for other factors, no statistically significant associations between education, income, and lifetime workplace eye injury were found among women. Socioeconomic status was associated with lifetime risk for workplace eye injury among men but not women. Greater public awareness of individual and societal impacts of workplace eye injuries, especially among socioeconomically disadvantaged men, could help support efforts to develop a coordinated prevention strategy to minimize avoidable workplace eye injuries.

To determine whether librarian and information specialist authorship was associated with better reported systematic review (SR) search quality. SRs from high-impact general internal medicine journals were reviewed for search quality characteristics and reporting quality by independent reviewers using three instruments, including a checklist of Institute of Medicine Recommended Standards for the Search Process and a scored modification of the Peer Review of Electronic Search Strategies instrument. The level of librarian and information specialist participation was significantly associated with search reproducibility from reported search strategies (Χ(2) = 23.5; P Librarian co-authored SRs had significantly higher odds of meeting 8 of 13 analyzed search standards than those with no librarian participation and six more than those with mentioned librarian participation. One-way ANOVA showed that differences in total search quality scores between all three groups were statistically significant (F2,267 = 10.1233; P librarian or information specialist co-authors are correlated with significantly higher quality reported search strategies. To minimize bias in SRs, authors and editors could encourage librarian engagement in SRs including authorship as a potential way to help improve documentation of the search strategy.

The elimination or reduction of risk is a prime requirement of all healthcare workers. The matter has come to the fore in dermatological practice recently with the widespread use of effective drugs that have significant side-effects (e.g. retinoids, cytotoxic drugs, biologics), the increase in skin surgery, especially for skin cancer, and the extensive use of phototherapies. To examine the available database from different agencies to which adverse events may be reported over at least a 5-year time frame, categorize the risks, look forward to where as yet unidentified risks might exist, and draw conclusions to improve the safety of dermatological practice. This work came about through a request from the National Patient Safety Agency [to the Joint Specialty Committee of the British Association of Dermatologists (BAD) and Royal College of Physicians] for information on risks to patients receiving treatment or investigation for skin disease. Organizations in the U.K. that receive information about adverse events, whether caused by drugs or procedures in dermatological treatments, were approached for information about reported events over a 5-year (or, in one case, 10-year) time frame up to 2009. Data were received from the National Patient Safety Agency, the Medicines and Healthcare Products Regulatory Agency, the National Health Service Litigation Authority, the Medical Protection Society and the Medical Defence Union. In addition, the results of a survey conducted in 2010 by the BAD of its members concerning potential critical incident reporting were included. The received information was analysed according to category of event and conclusions drawn about how best to manage the risks that were identified. Adverse events were divided into the following categories, listed in order of the number of reports received: drug side-effects (biologics and retinoids), phototherapy dosage, drug monitoring (including initial screening), pregnancy prevention programmes, skin

We empirically examine the reporting on biotechnology in Kenyan and international newspapers between 2010 and early 2014. We identify news articles that reported on biotechnology and analyze their use of words to determine whether there is a balance in the reporting of perceived risks and benefits. We also consider how the sources used in news articles and how the publication of the Séralini study of rats fed genetically modified maize affect the balance of reporting of perceived risks and benefits. We find that in Kenyan news reporting, more articles mention perceived benefits than risks, but when risks are mentioned, new articles contain more references to risks than to benefits. We also find that sources affect the reporting of perceived risks and benefits and that the Séralini study increased the likelihood that perceived risks are reported in Kenyan news reporting, but not in international newspapers. © The Author(s) 2015.

health problem priority in Indonesia. This paper presents an assessment of severe visual impairments related to the risk of MED. Methods: This paper assessed a part of Basic Health Research (Riskesdas 2007 data. For this assessment, subjects 15 years old or more had their visual acuity measured using the Snellen chart and their mental health status determined using the Self Reporting Questionnaire (SRQ 20. A subject was considered to have probable MED if the subject had a total score of 6 or more on the SRQ. Based on the measure of visual acuity, visual acuity was divided into 3 categories: normal/mild (20/20 to 20/60; low vision (less than 20/60 to 3/60; and blind (less than 3/60 to 0/0. Results: Among 972,989 subjects, 554,886 were aged 15 years or older. 11.4% of the subjects had probable MED. The prevalence of low vision and blindness was 5.1% and 0.9%, respectively. Compared to subjects with normal or mild visual impairments, subjects with low vision had a 74% increased risk for probable MED [adjusted relative risk (RRa=1,75; 95% confidence interval (CI=1,71-1,79]. Blind subjects had a 2.7-fold risk to be probable MED (RRa=2.69; 95% CI=2.60-2.78] compared to subjects with normal or mild visual impairments. Conclusion: Visual impairment severity increased probable MED risk. Therefore, visual impairment subjects need more attention on probable MED. (Health Science Indones 2011;2:9-13

Purpose: To test the hypotheses that (1) the increased risk of stroke conferred by childhood cranial radiation therapy (CRT) persists into adulthood; and (2) atherosclerotic risk factors further increase the stroke risk in cancer survivors. Methods and Materials: The Childhood Cancer Survivor Study is a multi-institutional retrospective cohort study of 14,358 5-year survivors of childhood cancer and 4023 randomly selected sibling controls with longitudinal follow-up. Age-adjusted incidence rates of self-reported late-occurring (≥5 years after diagnosis) first stroke were calculated. Multivariable Cox proportional hazards models were used to identify independent stroke predictors. Results: During a mean follow-up of 23.3 years, 292 survivors reported a late-occurring stroke. The age-adjusted stroke rate per 100,000 person-years was 77 (95% confidence interval [CI] 62-96), compared with 9.3 (95% CI 4-23) for siblings. Treatment with CRT increased stroke risk in a dose-dependent manner: hazard ratio 5.9 (95% CI 3.5-9.9) for 30-49 Gy CRT and 11.0 (7.4-17.0) for 50+ Gy CRT. The cumulative stroke incidence in survivors treated with 50+ Gy CRT was 1.1% (95% CI 0.4-1.8%) at 10 years after diagnosis and 12% (95% CI 8.9-15.0%) at 30 years. Hypertension increased stroke hazard by 4-fold (95% CI 2.8-5.5) and in black survivors by 16-fold (95% CI 6.9-36.6). Conclusion: Young adult pediatric cancer survivors have an increased stroke risk that is associated with CRT in a dose-dependent manner. Atherosclerotic risk factors enhanced this risk and should be treated aggressively.

We evaluated the relationship between the HO1 genotype, ferritin levels and the risk of type-2 diabetes and inflammation. Eight hundred thirty-five individuals were evaluated and classified according to their nutritional status and the presence of type-2 diabetes: 153 overweight (OW); 62 obese (OB); 55 type-2 diabetes mellitus (DM); 202 OWDM; 239 OBDM and 124 controls (C). We studied biochemical (glycemia, insulin, lipid profile, liver enzyme, creatinine, hsCRP), hematological (hemoglobin, free erythrocyte protoporphyrin, transferrin receptor and serum Fe and ferritin) and oxidative stress (SOD, GHS and TBARS) parameters. We determined heme oxygenase activity and the (GT)n polymorphism in its gene promoter. Individuals with diabetes, independent of nutritional status, showed high levels of ferritin and HO activity compared to control subjects. Allelic frequency was not different between the groups (Chi(2), NS) however, genotypes were different (Chi(2), P1). The SS (short-short) genotype was higher in all DM individuals compared to controls and MM was higher in controls. SM (short-medium) genotype was an independent risk factor for DM in logistic regression analysis. We observed high risk for type-2 diabetes mellitus in the presence of SM genotype and high levels of ferritin (OR adjusted: 2.7; 1.9-3.6; p1; compared to control group). It was also significantly related to inflammation. The SM genotype in HO1 gene promoter and ferritin levels were associated with higher risk for type-2 diabetes and for having a higher marker of inflammation, which is the main risk factor for the development of chronic diseases.

This report raises doubts on the validity of using LNT (linear no-threshold) relationship for evaluating the carcinogenic risk of low doses (< 100 mSv) and even more for very low doses (< 10 mSv). The LNT concept can be a useful pragmatic tool for assessing rules in radioprotection for doses above 10 mSv; however since it is not based on biological concepts of our current knowledge, it should not be used without precaution for assessing by extrapolation the risks associated with low and even more so, with very low doses (< 10 mSv), especially for benefit-risk assessments imposed on radiologists by the European directive 97-43. The biological mechanisms are different for doses lower than a few dozen mSv and for higher doses. The eventual risks in the dose range of radiological examinations (0.1 to 5 mSv, up to 20 mSv for some examinations) must be estimated taking into account radiobiological and experimental data. An empirical relationship which has been just validated for doses higher than 200 mSv may lead to an overestimation of risks (associated with doses one hundred fold lower), and this overestimation could discourage patients from undergoing useful examinations and introduce a bias in radioprotection measures against very low doses (< 10 mSv). Decision makers confronted with problems of radioactive waste or risk of contamination, should re-examine the methodology used for the evaluation of risks associated with very low doses and with doses delivered at a very low dose rate. This report confirms the inappropriateness of the collective dose concept to evaluate population irradiation risks

There is increasing interest in understanding how parent supervision influences young children's risk of injury, but nearly all of this research has been conducted with mothers. The present study compared first-time mothers' and fathers' supervisory beliefs and reported practices, and related these scores to parental reports of their child's history of injuries. Mothers and fathers of children 2-5 years each independently completed a telephone interview and previously validated questionnaires about their supervisory beliefs and practices and their child's history of injuries. Mothers and fathers provided similar reports of their child's injuries (minor, medically attended) and scored similarly on various supervision indices. Despite these similarities, the way mothers' and fathers' supervision indices related to children's injury history scores differed. Children's frequency of minor and medically attended injuries was predicted from maternal supervisory scores but not from paternal scores. Maternal supervision has more impact on children's risk of injury than paternal supervision, possibly because mothers spend more time with children than fathers.

Intimate partner violence (IPV) victimization is linked to sexual risk exposure among women. However, less is known about the intersection of IPV perpetration and sexual risk behavior among men. This study used data from a diverse, community sample of 334 heterosexually active young men, aged 18 to 25, across the United States to examine whether and how men with distinct IPV-related behavior patterns differed in sexual risk-related behavior and attitudes. Participants were recruited and surveyed online, and grouped conceptually based on the types of IPV perpetration behavior(s) used in a current or recent romantic relationship. Groups were then compared on relevant sexual risk variables. Men reporting both physical abuse and sexual coercion against intimate partners reported significantly higher numbers of lifetime partners, higher rates of nonmonogamy, greater endorsement of nonmonogamy, and less frequent condom use relative to nonabusive men or those reporting controlling behavior only. This group also had higher sexually transmitted infection (STI) exposure compared to men who used controlling behavior only and men who used sexual coercion only. Findings suggest that interventions with men who use physical and sexual violence need to account for not only the physical and psychological harm of this behavior but also the sexual risk to which men may expose their partners.

This paper reports observations and preliminary investigations in the first phase of a research program covering methodologies for making safety-related decisions. The objective has been to gain insight into NRC perceptions of the value of formal decision methods, their possible applications, and how risk is, or may be, incorporated in decision making. The perception of formal decision making techniques, held by various decision makers, and what may be done to improve them, were explored through interviews with NRC staff. An initial survey of decision making methods, an assessment of the applicability of formal methods vis-a-vis the available information, and a review of methods of incorporating risk and uncertainty have also been conducted.

To establish the prevalence of nutrition risk and associated risk factors among adults of advanced age newly admitted to hospital. A cross-sectional study was undertaken in adults aged over 85 years admitted to one of two hospital wards in Auckland within the previous 5 days. An interviewer-administered questionnaire was used to establish participant's socio-demographic and health characteristics. Markers of body composition and muscle strength were collected. Nutrition risk was assessed using the Mini Nutritional Assessment-Short Form (MNA-SF), dysphagia risk using the 10-Item Eating Assessment Tool (EAT-10) and level of cognition using the Montreal Cognitive Assessment. A total of 88 participants with a mean age of 90.0 ± 3.7 years completed the assessments. A third (28.4%) of the participants were categorised by the MNA-SF as malnourished and 43.2% were classified at risk of malnutrition. A third (29.5%) were at risk of dysphagia as assessed by EAT-10. Malnourished participants were more likely to be at risk of dysphagia (P = 0.015). The MNA-SF score was positively correlated with body mass index (r = 0.484, P strength (r = 0.250, P = 0.026) and negatively correlated with risk of dysphagia (r = -0.383, P strength and negatively correlated with dysphagia risk. Findings highlight the importance of screening for dysphagia risk, especially in those identified to be malnourished or at nutrition risk. © 2017 Dietitians Association of Australia.

Full Text Available Abstract Background Lower-than-expected incidence of HIV undermines sample size calculations and compromises the power of a HIV prevention trial. We evaluated the effectiveness of interim monitoring of HIV infection rates and on-going modification of recruitment strategies to enroll women at higher risk of HIV in the Cellulose Sulfate Phase III study in Nigeria. Methods We analyzed prevalence and incidence of HIV and other sexually transmitted infections, demographic and sexual behavior characteristics aggregated over the treatment groups on a quarterly basis. The site investigators were advised on their recruitment strategies based on the findings of the interim analyses. Results A total of 3619 women were screened and 1644 enrolled at the Ikeja and Apapa clinics in Lagos, and at the Central and Peripheral clinics in Port Harcourt. Twelve months after study initiation, the overall incidence of HIV was less than one-third of the pre-study assumption, with rates of HIV that varied substantially between clinics. Due to the low prevalence and incidence rates of HIV, it was decided to close the Ikeja clinic in Lagos and to find new catchment areas in Port Harcourt. This strategy was associated with an almost two-fold increase in observed HIV incidence during the second year of the study. Conclusion Given the difficulties in estimating HIV incidence, a close monitoring of HIV prevalence and incidence rates during a trial is warranted. The on-going modification of recruitment strategies based on the regular analysis of HIV rates appeared to be an efficient method for targeting populations at greatest risk of HIV infection and increasing study power in the Nigeria trial. Trial Registration The trial was registered with the ClinicalTrials.gov registry under #NCT00120770 http://clinicaltrials.gov/ct2/show/NCT00120770
Impact of acculturation on cardiovascular risk factors among elderly Mexican Americans.
López, Lenny; Peralta, Carmen A; Lee, Anne; Zeki Al Hazzouri, Adina; Haan, Mary N
2014-10-01
Higher levels of acculturation among Latinos have been shown to be associated with a higher prevalence of cardiovascular (CV) risk factors in some studies of middle-age persons. The association of acculturation and prevalence of CV risk factors in elderly Latinos is less well established. Acculturation was measured using the validated bidimensional Acculturation Rating Scale for Mexican Americans-II. We conducted a cross-sectional analysis of the association of acculturation with prevalence of CV risk factors among 1789 elderly men and women from the Sacramento Area Latino Study on Aging using multivariate linear and logistic regression. We tested for the interaction of acculturation with risk factors by nativity status. Median age was 69.8 years. Higher acculturation was associated with lower systolic blood pressure, lower low-density lipoprotein, higher high-density lipoprotein, and lower prevalence of CV disease after age and sex adjustment. Higher acculturation remained associated with lower level of low-density lipoprotein and higher level of high-density lipoprotein after full adjustment. Nativity status did not affect these results. Contrary to other reports in middle-aged persons, higher levels of acculturation were associated with better lipid profiles and no significant differences in other CV risk factors by acculturation level in elderly Latinos.

Full Text Available Amy Joy Lanou1, Barbara Svenson21Department of Health and Wellness, 2Ramsey Library, University of North Carolina Asheville, Asheville, NC, USAAbstract: This report reviews current evidence regarding the relationship between vegetarian eating patterns and cancer risk. Although plant-based diets including vegetarian and vegan diets are generally considered to be cancer protective, very few studies have directly addressed this question. Most large prospective observational studies show that vegetarian diets are at least modestly cancer protective (10%–12% reduction in overall cancer risk although results for specific cancers are less clear. No long-term randomized clinical trials have been conducted to address this relationship. However, a broad body of evidence links specific plant foods such as fruits and vegetables, plant constituents such as fiber, antioxidants and other phytochemicals, and achieving and maintaining a healthy weight to reduced risk of cancer diagnosis and recurrence. Also, research links the consumption of meat, especially red and processed meats, to increased risk of several types of cancer. Vegetarian and vegan diets increase beneficial plant foods and plant constituents, eliminate the intake of red and processed meat, and aid in achieving and maintaining a healthy weight. The direct and indirect evidence taken together suggests that vegetarian diets are a useful strategy for reducing risk of cancer.Keywords: diet, vegan, prevention

Multiple risk factor syndrome is a clustering of cardiovascular risk factors, such as diabetes, dyslipidemia, hypertension, and obesity associated epidemiologically with insulin resistance. This report describes the clinical course of a patient suffering from severe periodontitis with multiple risk factor syndrome, and discusses the association between periodontal infection and systemic health. The patient had a history of type 2 diabetes, dyslipidemia, and hypertension for over 10 years. At baseline, her hemoglobin A1 c was 8.1%. However, she had no diabetic complications except periodontitis. The IgG antibody titers against Porphyromonas gingivalis FDC 381 and SU63 were elevated above the mean of healthy subjects +2 standard deviations. Intensive periodontal treatment, including periodontal surgery, was performed to reduce periodontal infection and bacteremia. Her systemic and periodontal conditions were evaluated longitudinally for 10 years. Following periodontal treatment, antibody titers against Porphyromonas gingivalis and hemoglobin A1c values were significantly improved. The other clinical data and medication for her systemic condition also remained stable during supportive periodontal therapy. However, she developed myocardial infarction, and showed continuous deterioration of hemoglobin A1 c level and periodontitis. The long-term clustering of risk factors, such as diabetes, dyslipidemia, hypertension, and periodontitis, are associated with the development of myocardial infarction. Treatment of systemic conditions in combination with comprehensive periodontal treatment is important in management of patients with multiple risk factor syndrome.

This study investigated whether glycemic index (GI) or glycemic load (GL) of morning or evening intake and morning or evening carbohydrate intake from low- or higher-GI food sources (low-GI-CHO, higher-GI-CHO) during adolescence are relevant for risk markers of type 2 diabetes in young adulthood. Methods: Analyses included DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study participants who had provided at least two 3-day weighed dietary records (median: 7 records) during adolescence and one blood sample in young adulthood. Using multivariable linear regression analyses, estimated morning and evening GI, GL, low-GI-CHO (GI adolescence were not associated with any of the adult risk markers. A higher evening GI during adolescence was related to an increased HSI in young adulthood ( p = 0.003). A higher consumption of higher-GI-CHO in the evening was associated with lower insulin sensitivity ( p = 0.046) and an increased HSI ( p = 0.006), while a higher evening intake of low-GI-CHO was related to a lower HSI ( p = 0.009). Evening intakes were not related to FLI or the pro-inflammatory-score (all p > 0.1). Conclusion: Avoidance of large amounts of carbohydrates from higher-GI sources in the evening should be considered in preventive strategies to reduce the risk of type 2 diabetes in adulthood.

Background Variations in the distribution of cardiovascular disease and risk factors by socioeconomic status (SES) have been described in affluent societies, yet a better understanding of these patterns is needed for most low- and middle-income countries. Objective This study sought to describe the relationship between cardiovascular risk factors and SES using monthly family income, educational attainment, and assets index, in 4 Peruvian sites. Methods Baseline data from an age- and sex-stratified random sample of participants, ages ≥35 years, from 4 Peruvian sites (CRONICAS Cohort Study, 2010) were used. The SES indicators considered were monthly family income (n = 3,220), educational attainment (n = 3,598), and assets index (n = 3,601). Behavioral risk factors included current tobacco use, alcohol drinking, physical activity, daily intake of fruits and vegetables, and no control of salt intake. Cardiometabolic risk factors included obesity, elevated waist circumference, hypertension, insulin resistance, diabetes mellitus, low high-density lipoprotein cholesterol, and high triglyceride levels. Results In the overall population, 41.6% reported a monthly family income education. Important differences were noted between the socioeconomic indicators: for example, higher income and higher scores on an asset index were associated with greater risk of obesity, whereas higher levels of education were associated with lower risk of obesity. In contrast, higher SES according to all 3 indicators was associated with higher levels of triglycerides. Conclusions The association between SES and cardiometabolic risk factors varies depending on the SES indicator used. These results highlight the need to contextualize risk factors by socioeconomic groups in Latin American settings. PMID:27102029

The Pacific Northwest Laboratory (PNL)(1) effort on the overall Baseline Environmental Management Report (BEMR) project consists of four installation-specific work components performed in succession. These components include (1) development of source terms, 92) collection of data and preparation of environmental settings reports, (3) calculation of unit risk factors, and (4) utilization of the unit risk factors in Automated Remedial Action Methodology (ARAM) for computation of target concentrations and cost estimates. This report documents work completed for the Nevada Test Site, Nevada, for components 2 and 3. The product of this phase of the BEMR project is the development of unit factors (i.e., unit transport factors, unit exposure factors, and unit risk factors). Thousands of these unit factors are gene rated and fill approximately one megabyte of computer information per installation. The final unit risk factors (URF) are transmitted electronically to BEMR-Cost task personnel as input to a computer program (ARAM). Abstracted files and exhibits of the URF information are included in this report. These visual formats are intended to provide a sample of the final task deliverable (the URF files) which can be easily read without a computer

Retrospective pre-immigration data on sexual risk and alcohol use behaviours was collected from 527 recent Latino immigrants to the USA, aged 18-34. Two follow-up assessments (12 months apart) reported on post-immigration behaviours. Using a mixed model growth curve analysis, a six-level sexual risk change variable was constructed combining measures of sexual partners and condom use. The mixed model growth curve was also used to examine associations between changes in sexual risk behaviour and changes in alcohol use and for testing interaction effects of gender and documentation status. Results suggest that individuals with high sexual risk behaviour at pre-immigration converge to low/moderate risk post-immigration, and that those who were sexually inactive or had low sexual risk at pre-immigration increased their risk post-immigration. Individuals with moderately higher initial but decreasing sexual risk behaviour showed the steepest decline in alcohol use, but their drinking at Time 3 was still higher than individuals reporting low sexual risk at Time 1. On average, men drank more than women, except women in one of the highest sexual risk categories at Time 1 - who seemed to drink as much, if not more, than men. Undocumented men reported more frequent drinking than documented men. In contrast, undocumented women reported lower alcohol use than documented women.

Responders to acute-phase cognitive therapy (A-CT) for major depressive disorder (MDD) often relapse or recur, but continuation-phase cognitive therapy (C-CT) or fluoxetine reduces risks for some patients. We tested composite moderators of C-CT versus fluoxetine's preventive effects to inform continuation treatment selection. Responders to A-CT for MDD judged to be at higher risk for relapse due to unstable or partial remission (N=172) were randomized to 8 months of C-CT or fluoxetine with clinical management and assessed, free from protocol treatment, for 24 additional months. Pre-continuation-treatment characteristics that in survival analyses moderated treatments' effects on relapse over 8 months of continuation-phase treatment (residual symptoms and negative temperament) and on relapse/recurrence over the full observation period's 32 months (residual symptoms and age) were combined to estimate the potential advantage of C-CT versus fluoxetine for individual patients. Assigning patients to optimal continuation treatment (i.e., to C-CT or fluoxetine, depending on patients' pre-continuation-treatment characteristics) resulted in absolute reduction of relapse or recurrence risk by 16-21% compared to the other non-optimal treatment. Although these novel results require replication before clinical application, selecting optimal continuation treatment (i.e., personalizing treatment) for higher risk A-CT responders may decrease risks of MDD relapse and recurrence substantively.

To report the incidence of objective and subjective neurosensory disturbance (NSD) after orthognathic surgery in a major orthognathic centre in Hong Kong, and to investigate the risk factors that contributed to the incidence of NSD after orthognathic surgery. A retrospective cross-sectional study on NSD after orthognathic surgery in a local major orthognathic centre. Patients who had bimaxillary orthognathic surgery reviewed at post-operative 6 months, 12 months or 24 months were recruited to undergo neurosensory tests with subjective and 3 objective assessments. Possible risk factors of NSD including subjects' age and gender, surgical procedures and surgeons' experience were analyzed. 238 patients with 476 sides were recruited. The incidences of subjective NSD after maxillary procedures were 16.2%, 13% and 9.8% at post-operative 6 months, 12 months and 24 months, respectively; the incidences of subjective NSD after mandibular procedures were 35.4%, 36.6% and 34.6% at post-operative 6 months, 12 months and 24 months, respectively. Increased age was found to be a significant risk factor of NSD after orthognathic surgery at short term (at 6 months and 12 months) but not at 24 months. SSO has a significantly higher risk of NSD when compared to VSSO. SSO in combination with anterior mandibular surgery has a higher risk of NSD when compared to VSSO in combination with anterior mandibular surgery or anterior mandibular surgery alone. Gender of patients and surgeons' experience were not found to be risk factors of NSD after orthognathic surgery. The incidence of NSD after maxillary and mandibular orthognathic procedures at post-operative 6 months, 12 months and 24 months was reported. Increased age was identified as a risk factor of short term post-operative NSD but not in long term (24 months or more). Specific mandibular procedures were related to higher incidence of NSD after orthognathic surgery.

Full Text Available Information Technology (IT has become an integral part of virtually all modern day organisations. The advent of IT has given rise to numerous benefits which increase productivity and efficiency in the workplace, however, IT also brings with it significant risks that can have an impact on an organisation’s ability to function as a going concern. Organisations, especially those listed on the Johannesburg Stock Exchange (JSE, are required to submit an Integrated Report (IR on an annual basis in which they indicate how they used the resources at their disposal to create value for the organisation and its stakeholders during the year under review. The IR is also a forward-looking document, as opposed to the traditional, backward-looking reports. The purpose of this paper is to determine to what extent IT Risk and IT Risk Management are disclosed in the IR’s of the Top 40 Listed Companies on the JSE. It further aims to determine whether IT Risks are included as material risk in the entity’s risk statements of the Integrated Report, and whether proper explanations are provided on how the materiality of the risks are determined and dealt with. This is done by means of an empirical study consisting of a content analysis of the IRs of the Top 40 listed companies on the JSE. The results of the analysis indicates that more than half of the companies included IT risk as part of their material risks and outlined appropriate and detailed processes that were followed by the company to manage those IT risks. The findings of the study accordingly support the need for communicating significant risks and the management thereof to stakeholders as part of the integrated nature of governance of entities. However, it is disconcerting that some companies are not doing this, and accordingly are not realising the need for communicating significant matters to their stakeholders and the value that informative and credible reporting will bring to an entity

This non-governmental association works to empower and improve farmworkers’ living and working conditions. The field trip is embedded in my research on risk communication with a special focus on the risks of herbicides. This issue is closely linked to political, cultural and racial factors. Hence, I argue, risk communication must consider culture as a contextual key factor and should embrace a critical perspective. Such a perspective is culturally appropriate and addresses issues of race and language as well as socio-economic status

Adults with intellectual disabilities (IDs) experience a higher incidence of injury, compared with the general population. The aim of this study was to investigate the provision of aids and adaptations, residential service providers' individual risk assessments and training in these, and injury incident recording and reporting procedures, in relation to injury prevention. Interviews were conducted with a community-based cohort of adults with IDs (n = 511) who live in Greater Glasgow, Scotland, UK and their key carer (n = 446). They were asked about their aids and adaptations at home, and paid carers (n = 228) were asked about individual risk assessments, their training, and incident recording and reporting procedures. Four hundred and twelve (80.6%) of the adults with IDs had at least one aid or adaptation at home to help prevent injury. However, a proportion who might benefit, were not in receipt of them, and surprisingly few had temperature controlled hot water or a bath thermometer in place to help prevent burns/scalds, or kitchen safety equipment to prevent burns/scalds from electric kettles or irons. Fifty-four (23.7%) of the paid carers were not aware of the adult they supported having had any risk assessments, and only 142 (57.9%) had received any training on risk assessments. Considerable variation in incident recording and reporting procedures was evident. More work is needed to better understand, and more fully incorporate, best practice injury prevention measures into routine support planning for adults with IDs within a positive risk-taking and risk reduction framework. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Full Text Available We compared South Koreans with Australians in order to characterize cultural differences in attitudes and choices regarding risk, at both the individual and group levels. Our results showed that Australians, when assessed individually, consistently self-reported higher preference for risk than South Koreans, regardless of gender. The data revealed that South Koreans, regardless of gender composition, were willing to take greater risks when making decisions in group decision-making situations than when they were alone. This is a different pattern from that seen in the Australian sample, in which a risky shift was noted only among males. This difference was attributed to the influence of various cultural orientations (independent vs. interdependent relationship styles. This study also provides a discussion of the implications of these results in terms of cultural differences in attitudes and decisions regarding risk.

Communication about melanoma and risk reduction after melanoma diagnosis.
Rodríguez, Vivian M; Berwick, Marianne; Hay, Jennifer L
2017-12-01
Melanoma patients are advised to perform regular risk-reduction practices, including sun protection as well as skin self-examinations (SSEs) and physician-led examinations. Melanoma-specific communication regarding family risk and screening may promote such behaviors. To this end, associations between patients' melanoma-specific communication and risk reduction were examined. Melanoma patients (N = 169) drawn from a population-based cancer registry reported their current risk-reduction practices, perceived risk of future melanoma, and communication with physicians and relatives about melanoma risk and screening. Patients were, on average, 56 years old and 6.7 years' post diagnosis; 51% were male, 93% reported "fair/very fair" skin color, 75% completed at least some college, and 22% reported a family history of melanoma. Patients reported varying levels of regular (always/nearly always) sun protection: sunscreen use (79%), shade seeking (60%), hat use (54%), and long-sleeve shirt use (30%). Only 28% performed thorough SSE regularly, whereas 92% reported undergoing physician-led skin examinations within the past year. Participants who were female, younger, and had a higher perceived risk of future melanoma were more likely to report past communication. In adjusted analyses, communication remained uniquely associated with increased sunscreen use and SSE. Encouraging melanoma patients to have a more active role in discussions concerning melanoma risk and screening with relatives and physicians alike may be a useful strategy to promote 2 key risk-reduction practices post melanoma diagnosis and treatment. Future research is needed to identify additional strategies to improve comprehensive risk reduction in long-term melanoma patients. Copyright © 2016 John Wiley & Sons, Ltd.

Bleeding into the vertebral canal causing a spinal haematoma (SH) is a rare but serious complication to central neuraxial blocks (CNB). Of all serious complications to CNBs such as meningitis, abscess, cardiovascular collapse, and nerve injury, neurological injury associated with SH has the worst prognosis for permanent harm. Around the turn of the millennium, the first guidelines were published that aimed to reduce the risk of this complication. These guidelines are based on known risk factors for SH, rather than evidence from randomised, controlled trials (RCTs). RCTs, and therefore meta-analysis of RCTs, are not appropriate for identifying rare events. Analysing published case reports of rare complications may at least reveal risk factors and can thereby improve management of CNBs. The aims of the present review were to analyse case reports of SH after CNBs published between 1994 and 2015, and compare these with previous reviews of case reports. MEDLINE and EMBASE were used for identifying case reports published in English, German, or Scandinavian languages, using appropriate search terms. Reference lists were also scrutinised for case reports. Twenty different variables from each case were specifically searched for and filled out on an Excel spreadsheet, and incidences were calculated using the number of informative reports as denominator for each variable. Altogether 166 case reports on spinal haematoma after CNB published during the years between 1994 and 2015 were collected. The annual number of case reports published during this period almost trebled compared with the two preceding decades. This trend continued even after the first guidelines on safe practice of CNBs appeared around year 2000, although more cases complied with such guidelines during the second half of the observation period (2005-2015) than during the first half. Three types of risk factors dominated: (1) Patient-related risk factors such as haemostatic and spinal disorders, (2) CNB

Full Text Available Higher education institutions are going through a different reform processes that differ from country to country. However, the common challenge of higher education institutions is to assure the financial sustainability and only those institutions that have stable financial structure will be able to fulfil their missions and goals in conditions of limited financial resources. One of very important preconditions for assuring financial sustainability is a high quality reporting system, providing comprehensive and detailed information about all aspects of the activities, performed by an institution of higher education and, especially, its full costs. The objective of the paper is two-fold. On the one hand, its aim is to address reform processes regarding reporting systems at higher education institutions in selected countries; Bosnia and Herzegovina, Croatia and Slovenia, and on the other hand, to highlight most important obstacles for development of efficient internal reporting systems. The empirical research was conducted in 2016 and data collection was based on the survey method. The questionnaires were sent to all public higher education institutions in Bosnia and Herzegovina, Croatia and Slovenia. The results of research have shown that, even though there is a positive perception regarding the need to improve existing internal reporting systems, there are significant differences in obstacles for development of efficient internal reporting systems in observed countries.

The aim of this cross-sectional study was to observe whether environmental factors and phenotypic traits are associated with owner-reported skin problems and with veterinary diagnosed canine atopic dermatitis (CAD). Data were collected using the validated online DOGRISK questionnaire. Out of the data that the questionnaire provides for analysis, focus was first turned towards addressing questions regarding 'Atopy/allergy (skin symptoms)' using a total of 8643 dogs: 1585 dogs with owner-reported allergic/atopic skin symptoms and 7058 dogs without. A subsequent analysis compared dogs with veterinary-verified CAD (n = 322) as a case group against the 7058 dogs without owner-reported skin symptoms. The association between 21 factors related to the environment, canine phenotypes and breed groups within both populations were analysed using univariable and multivariable logistic regression. The environmental factors that showed a significant inverse association with the risk of owner-reported allergic/atopic skin symptoms were as following: whether the dog was living in a detached house, whether there were other dogs in the household, and whether the dog was born in the current household. Having over 50% white colour in the coat and living in an extremely clean household were significantly associated with an increased risk of owner-reported allergic/atopic skin symptoms. The five breeds demonstrating the highest proportion of owner-reported allergic/atopic skin symptoms were West Highland white terrier, Boxer, English bulldog, Dalmatian and French bulldog. The Fédération Cynologique Internationale dog breed groups 3 (Terriers) and 6 (Scent hounds and related breeds) showed a significantly higher risk for owner-reported allergic/atopic skin symptoms than mixed breed dogs. In the second population, the inverse association was observed between the risk of CAD and the presence of other dogs in the household, and whether the dog had been born in the current household. The

Full Text Available Abstract Background The media play an important role at the interface of science and policy by communicating scientific information to the public and policy makers. In issues of theoretical risk, in which there is scientific uncertainty, the media's role as disseminators of information is particularly important due to the potential to influence public perception of the severity of the risk. In this article we describe how the Canadian print media reported the theoretical risk of blood transmission of Creutzfeldt-Jakob disease (CJD. Methods We searched 3 newspaper databases for articles published by 6 major Canadian daily newspapers between January 1990 and December 1999. We identified all articles relating to blood transmission of CJD. In duplicate we extracted information from the articles and entered the information into a qualitative software program. We compared the observations obtained from this content analysis with information obtained from a previous policy analysis examining the Canadian blood system's decision-making concerning the potential transfusion transmission of CJD. Results Our search identified 245 relevant articles. We observed that newspapers in one instance accelerated a policy decision, which had important resource and health implication, by communicating information on risk to the public. We also observed that newspapers primarily relied upon expert opinion (47 articles as opposed to published medical evidence (28 articles when communicating risk information. Journalists we interviewed described the challenges of balancing their responsibility to raise awareness of potential health threats with not unnecessarily arousing fear amongst the public. Conclusions Based on our findings we recommend that journalists report information from both expert opinion sources and from published studies when communicating information on risk. We also recommend researchers work more closely with journalists to assist them in identifying

Methods: Analyses included DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD study participants who had provided at least two 3-day weighed dietary records (median: 7 records during adolescence and one blood sample in young adulthood. Using multivariable linear regression analyses, estimated morning and evening GI, GL, low-GI-CHO (GI < 55 and higher-GI-CHO (GI ≥ 55 were related to insulin sensitivity (N = 252, hepatic steatosis index (HSI, fatty liver index (FLI (both N = 253, and a pro-inflammatory-score (N = 249. Results: Morning intakes during adolescence were not associated with any of the adult risk markers. A higher evening GI during adolescence was related to an increased HSI in young adulthood (p = 0.003. A higher consumption of higher-GI-CHO in the evening was associated with lower insulin sensitivity (p = 0.046 and an increased HSI (p = 0.006, while a higher evening intake of low-GI-CHO was related to a lower HSI (p = 0.009. Evening intakes were not related to FLI or the pro-inflammatory-score (all p > 0.1. Conclusion: Avoidance of large amounts of carbohydrates from higher-GI sources in the evening should be considered in preventive strategies to reduce the risk of type 2 diabetes in adulthood.
Actual versus perceived peer sexual risk behavior in online youth social networks.

Perception of peer behaviors is an important predictor of actual risk behaviors among youth. However, we lack understanding of peer influence through social media and of actual and perceived peer behavior concordance. The purpose of this research is to document the relationship between individual perception of and actual peer sexual risk behavior using online social networks. The data are a result of a secondary analysis of baseline self-reported and peer-reported sexual risk behavior from a cluster randomized trial including 1,029 persons from 162 virtual networks. Individuals (seeds) recruited up to three friends who then recruited additional friends, extending three waves from the seed. ANOVA models compared network means of actual participant behavior across categories of perceived behavior. Concordance varied between reported and perceived behavior, with higher concordance between perceived and reported condom use, multiple partners, concurrent partners, sexual pressure, and drug and alcohol use during sex. Individuals significantly over-reported risk and under-reported protective peer behaviors related to sex.

National Institute of Radiological Sciences (NIRS) set up a phone consulting service early after Fukushima Nuclear Power Plant Accident and inquiries to the service attained over 14,000 at August end, 2011. This paper describes the process, present state and future view of the risk communication based on experiences through the service. The communication is classified in 3 stages of consensus/care in peacetime, crisis, and consensus/care post disaster. The first one contains the consensus of atomic power policy and provision of its information; the second, of evacuation/indoor evacuation and indication of restricted water and food intake; and the third, communication for changes and standard of radiation related matters. Initial inquiries to the NIRS service were many concerning examinations of radiation screening, decontamination and internal exposure, from inside and outside of Fukushima Prefecture, suggesting the concern had been spread to remote area from the Prefecture. Then, the time needed per inquiry/consultation prolonged, implying the wish for solving the concern. The risk communication and consideration for realizing radiation risk at peacetime might have rather unrealistic, which was thought to be the major cause of problems at crisis. In addition, interpretation of various values relating to radiation had been apparently different from expert to expert, and findings by radiation effects and rules of radiation protection had been confusedly understood, which probably influenced on people's correct understanding. However, it is conceivably a fruit of taken risk communication that the past understanding ''radiation, unseeable, is terrible'' has changed to the current understanding ''protection can be done through risk assessment of radiation, measurable''. Hereafter, important are the practical use of various numerical values officially informed and realization of dose through exposure routes, and dispatch of their integrated information to lessen the

Exposure to ionising radiation has been suggested as a causal risk factor for malignant pleural mesothelioma (MPM). Studies of patients treated by radiotherapy for primary cancers have suggested that radiation contributes to the development of secondary MPM. Here we examined the risk to nuclear workers of MPM related to exposure to low doses of occupational radiation at low dose rates. All results concerning MPM risk in published studies of nuclear workers were examined for their association with radiation exposure and potential confounders. We found 19 relevant studies. Elevated risks of pleural cancer were reported in most (15/17) of these studies. Eight reported risks higher for radiation monitored workers than for other workers. However, of 12 studies that looked at associations with ionising radiation, only one reported a significant dose-risk association. Asbestos was an important confounder in most studies. We conclude that studies of nuclear workers have not detected an association between ionising radiation exposure and MPM. Further investigations should improve the consideration of asbestos exposure at the same time as they address the risk of MPM related to occupational exposure of nuclear workers to low doses of ionising radiation at low dose rates.

Accident management is an important component to maintaining risk at acceptable levels for all complex systems, such as nuclear power plants. With the introduction of passive, or inherently safe, reactor designs the focus has shifted from management by operators to allowing the system's design to take advantage of natural phenomena to manage the accident. Inherently and passively safe designs are laudable, but nonetheless extreme boundary conditions can interfere with the design attributes which facilitate inherent safety, thus resulting in unanticipated and undesirable end states. This report examines an inherently safe and small sodium fast reactor experiencing a variety of beyond design basis events with the intent of exploring the utility of a Dynamic Bayesian Network to infer the state of the reactor to inform the operator's corrective actions. These inferences also serve to identify the instruments most critical to informing an operator's actions as candidates for hardening against radiation and other extreme environmental conditions that may exist in an accident. This reduction in uncertainty serves to inform ongoing discussions of how small sodium reactors would be licensed and may serve to reduce regulatory risk and cost for such reactors.

The Safety Report (SR) plays a crucial role within the nuclear licensing regime as the principal means for demonstrating the adequacy of safety analysis for a nuclear facility to ensure that it can be constructed, operated, maintained, shut down, and decommissioned safely and in compliance with applicable laws and regulations. It serves as the basis for granting authorizations for the commencement of the main stages of the facility’s life cycle as well as decision-making processes related to safety. Historically, the majority of nuclear safety reports have operated under rather prescriptive regimes, with emphasis placed on demonstrations of the robustness of the facility’s design (design safety) against prescriptive technical requirements set by the regulatory body, and less attention paid to demonstrating the adequacy and effectiveness of Operator’s management system for managing risks to daily operation.

Determine whether specific risk factors, symptoms and clinical examination findings are associated with hyperbaric oxygen therapy (HBOT) intolerance and subsequent tympanotomy tube placement. A retrospective case series with chart review was conducted from 2007 to 2016 of patients undergoing HBOT clearance at a tertiary care university hospital in an urban city. Eighty-one (n=81) patient charts were reviewed for risk factors, symptoms and clinical examination findings related to HBOT eustachian tube dysfunction and middle ear barotrauma. Relative risk was calculated for each variable to determine risk for HBOT intolerance and need for tympanotomy tube placement. Risk factor, symptom, physical examination and HBOT complication-susceptibility scores were calculated for each patient. Mean risk factor, clinical and HBOT complication-susceptibility scores were significantly higher in patients who did not tolerate HBOT compared to patients who tolerated HBOT. Patients reporting a history of otitis media, tinnitus, and prior ear surgery were at a higher risk for HBOT intolerance. Patients reporting a history of pressure intolerance and prior ear surgery were more likely to undergo tympanotomy tube placement. Patients noted to have otologic findings prior to HBOT were at a higher risk for both HBOT intolerance and tympanotomy tube placement. A thorough otolaryngological evaluation can potentially predict and identify patients at risk for HBOT intolerance and tympanotomy tube placement. Copyright © 2017 Elsevier Inc. All rights reserved.

Abstract Prostate cancer (PCa) is a common illness for aging males. Lycopene has been identified as an antioxidant agent with potential anticancer properties. Studies investigating the relation between lycopene and PCa risk have produced inconsistent results. This study aims to determine dietary lycopene consumption/circulating concentration and any potential dose–response associations with the risk of PCa. Eligible studies published in English up to April 10, 2014, were searched and identified from Pubmed, Sciencedirect Online, Wiley online library databases and hand searching. The STATA (version 12.0) was applied to process the dose–response meta-analysis. Random effects models were used to calculate pooled relative risks (RRs) and 95% confidence intervals (CIs) and to incorporate variation between studies. The linear and nonlinear dose–response relations were evaluated with data from categories of lycopene consumption/circulating concentrations. Twenty-six studies were included with 17,517 cases of PCa reported from 563,299 participants. Although inverse association between lycopene consumption and PCa risk was not found in all studies, there was a trend that with higher lycopene intake, there was reduced incidence of PCa (P = 0.078). Removal of one Chinese study in sensitivity analysis, or recalculation using data from only high-quality studies for subgroup analysis, indicated that higher lycopene consumption significantly lowered PCa risk. Furthermore, our dose–response meta-analysis demonstrated that higher lycopene consumption was linearly associated with a reduced risk of PCa with a threshold between 9 and 21 mg/day. Consistently, higher circulating lycopene levels significantly reduced the risk of PCa. Interestingly, the concentration of circulating lycopene between 2.17 and 85 μg/dL was linearly inversed with PCa risk whereas there was no linear association >85 μg/dL. In addition, greater efficacy for the circulating lycopene

To explore and compare perinatal and maternal outcomes in women at 'higher risk' of complications planning home versus obstetric unit (OU) birth. Prospective cohort study. OUs and planned home births in England. 8180 'higher risk' women in the Birthplace cohort. We used Poisson regression to calculate relative risks adjusted for maternal characteristics. Sensitivity analyses explored possible effects of differences in risk between groups and alternative outcome measures. Composite perinatal outcome measure encompassing 'intrapartum related mortality and morbidity' (intrapartum stillbirth, early neonatal death, neonatal encephalopathy, meconium aspiration syndrome, brachial plexus injury, fractured humerus or clavicle) and neonatal admission within 48 hours for more than 48 hours. Two composite maternal outcome measures capturing intrapartum interventions/adverse maternal outcomes and straightforward birth. The risk of 'intrapartum related mortality and morbidity' or neonatal admission for more than 48 hours was lower in planned home births than planned OU births [adjusted relative risks (RR) 0.50, 95% CI 0.31-0.81]. Adjustment for clinical risk factors did not materially affect this finding. The direction of effect was reversed for the more restricted outcome measure 'intrapartum related mortality and morbidity' (RR adjusted for parity 1.92, 95% CI 0.97-3.80). Maternal interventions were lower in planned home births. The babies of 'higher risk' women who plan birth in an OU appear more likely to be admitted to neonatal care than those whose mothers plan birth at home, but it is unclear if this reflects a real difference in morbidity. Rates of intrapartum related morbidity and mortality did not differ statistically significantly between settings at the 5% level but a larger study would be required to rule out a clinically important difference between the groups. © 2015 The Authors.

Previous research suggested that illness perceptions provide the basis for illness risk perceptions through an inductive reasoning process. This study aimed to assess the direction of relationships between illness and recurrence risk perceptions over time, among cardiac patients. A longitudinal study was conducted among 138 patients undergoing coronary angioplasty. Self-report questionnaires measured perceived recurrence risk and illness perceptions one day and one month after catheterisation. Cross-lagged Panel Model Analyses revealed that higher perceptions of timeline, consequences and emotional representations of illness at hospitalisation were associated with higher recurrence risk perceptions one month later. Perceived personal control was the only illness perception with bi-directional associations: higher perceived personal control at hospitalisation was associated with higher recurrence risk perceptions one month later; and higher recurrence risk perceptions at hospitalisation was associated with lower personal control one month later. The findings suggest that the associations between recurrence risk and illness perceptions can only partly be explained by inductive reasoning. Halo effects and defensive processes are suggested as complementary explanations for the observed associations between risk and illness perceptions.

This study deals with the impact of supercritical CO 2 injection in deep saline aquifer, but also addresses the case of depleted hydrocarbons fields. After a general presentation of the carbon capture and storage (CCS) technique, this report presents the main principles of risk analysis and defines an analysis method applicable to the whole CCS sector. It is based on practices coming from the field of industrial risk analysis, on the knowledge of underground processes, and on the state of the art of health risk analysis in the case of chemical species. The main considered risks are hydraulic risks (fluid pressurization), mechanical risks (cracking, soil rising and induced seismicity), CO 2 migration or leakages towards aquifers and surface, and migration of other species than CO 2 . The report addresses the characterisation of fluids and of possible geochemical evolutions, the characterisation of scenarios of fluid migration, and the hierarchy of health impacts related to fluid leakages

Women in military service are less fit and more likely to suffer musculoskeletal injuries during physical training than men. They also use more medical care during deployment than men. Using data from the Comprehensive Soldier and Family Fitness Global Assessment Tool 2.0 (GAT 2.0), self-reported health and lifestyle and behavioral risk factors were analyzed in nondeployed Army personnel, with the goals of examining (1) service-component differences across traditional risk and lifestyle factors, and (2) correlates of physical performance and physical activity-related injury. Self-report GAT 2.0 data included health risk factors (overall perceived health, sleep, diet, tobacco and alcohol use), self-reported health metrics (height, weight, Army Physical Fitness Test (APFT) scores), and history of physical activity-related injury. The GAT 2.0 was completed by 1,322 AD and 1,033 NG/R women, and APFT data were available for a subsample of 605 AD and 582 NG/R women. Initial analyses of GAT 2.0 data indicated that AD had higher rates of fair/poor perceived health, poor sleep, and unhealthy diet compared to NG/R women. However, AD women had a lower APFT fail rate (8%) than NG (27%) and R (28%). Active duty women were more likely to experience a physical injury in the past 6 months (38%) than NG (19%) and R (22%) women, and more likely to seek medical care than NG/R women. Across all service components, predictive factors for APFT failure included high body mass index (BMI), fair/poor health, and unhealthy diet. Predictive factors for physical injury included high BMI, fair/poor health, and binge drinking. Our analyses suggest that AD women Soldiers are more physically fit than NG/R women Soldiers, which is accompanied by a greater prevalence of physical

Background In Switzerland, health policies are decided at the local level, but little is known regarding their impact on the screening and management of cardiovascular risk factors (CVRFs). We thus aimed at assessing geographical levels of CVRFs in Switzerland. Methods Swiss Health Survey for 2007 (N = 17,879). Seven administrative regions were defined: West (Leman), West-Central (Mittelland), Zurich, South (Ticino), North-West, East and Central Switzerland. Obesity, smoking, hypertension, dyslipidemia and diabetes prevalence, treatment and screening within the last 12 months were assessed by interview. Results After multivariate adjustment for age, gender, educational level, marital status and Swiss citizenship, no significant differences were found between regions regarding prevalence of obesity or current smoking. Similarly, no differences were found regarding hypertension screening and prevalence. Two thirds of subjects who had been told they had high blood pressure were treated, the lowest treatment rates being found in East Switzerland: odds-ratio and [95% confidence interval] 0.65 [0.50-0.85]. Screening for hypercholesterolemia was more frequently reported in French (Leman) and Italian (Ticino) speaking regions. Four out of ten participants who had been told they had high cholesterol levels were treated and the lowest treatment rates were found in German-speaking regions. Screening for diabetes was higher in Ticino (1.24 [1.09 - 1.42]). Six out of ten participants who had been told they had diabetes were treated, the lowest treatment rates were found for German-speaking regions. Conclusions In Switzerland, cardiovascular risk factor screening and management differ between regions and these differences cannot be accounted for by differences in populations' characteristics. Management of most cardiovascular risk factors could be improved. PMID:22452881
Psychosocial pathways to childhood obesity: a pilot study involving a high risk preschool sample.

This pilot study adopts a systems theory perspective to explore associations between parent and child factors and children's body mass index (BMI). Forty mothers and their preschool-aged children (3-6years) who were eligible for Head Start were recruited. Measures included demographic risk, maternal depression, negative parenting, children's impulsivity, children's approach to eating, and BMI. Structural Equation Modeling supported a mediating model such that mothers who reported greater demographic risk and more depressive symptoms showed higher rates of negative parenting. In turn, more negative parenting predicted higher child impulsivity ratings, which were related to higher food approach scores. Finally, children who scored higher in food approach had higher BMIs. Tests of sub-models excluding any of the mediating variables indicated a significantly worse fit to the data in each case. Results have implications for family-wide intervention strategies to help lower the risk for early-onset obesity in high-risk children. Copyright © 2014 Elsevier Ltd. All rights reserved.

Full Text Available Background: Although some studies have identified hazardous substances in electronic cigarette (EC liquids and emissions, there is limited information about the health risks of using ECs. Methods: In this study, the U.S. Environmental Protection Agency (EPA health risk assessment model and findings of a literature review were used to determine and profile hazards. Focus was put on the toxicants reported in the literature on conventional cigarette (CC smoke that most strongly associated with adverse health effects. To evaluate their health risks, dose-response relationships and standard-use conditions were used to estimate average hazard exposures and to calculate the overall health risks of ECs and CCs, benchmarked against international guideline levels for each hazard. Results: Four hazards (acrolein, diethylene glycol, propylene glycol and cadmium reported in EC emissions and seven hazards (acetaldehyde, acrolein, formaldehyde, cadmium, CO, 4-(methylnitrosamino-1-(3-pyridyl-1-butanone (NNK, N′-nitrosonornicotine (NNN reported in CC emissions had maximum exposure levels higher than the guideline levels. Two hazards (acrolein, propylene glycol in EC emissions and five hazards (acetaldehyde, acrolein, formaldehyde, cadmium, NNN in CC emissions had average exposure levels higher than the guideline levels. Conclusions: Based on the conditions of use, ECs should be a safer nicotine-delivery product than CCs.

The majority of cases of endophthalmitis are caused by exogenous pathogens; only 5-10 % are of endogenous origin. One cause of these rare cases of endogenous endophthalmitis is Listeria monocytogenes. Twenty-six cases of endophthalmitis due to this pathogen have been published over the last twenty years. The aim of this review is to summarize the main risk factors and common clinical findings of endogenous endophthalmitis due to Listeria monocytogenes. We report on a 62-year-old female presenting with a sterile hypopyon iritis with secondary glaucoma and an underlying rheumatoid disease. In microbiological analysis we identified Listeria monocytogenes. Further we searched through all published cases for typical signs, risk factors, details of medical and surgical treatment and outcome of endogenous endophthalmitis due to this rare pathogen. Ocular symptoms in almost all of these published cases included pain, redness of the eye, and decreased vision. Main clinical features included elevated intraocular pressure and fibrinous anterior chamber reaction, as well as a dark hypopyon. While the infection is typically spread endogenously, neither an exogenous nor endogenous source of infection could be identified in most cases. Immunocompromised patients are at higher risk of being infected than immunocompetent patients. The clinical course of endophthalmitis caused by Listeria monocytogenes had different visual outcomes. In some cases, the infection led to enucleation, blindness, or strong visual loss, whereas most patients showed a tendency of visual improvement during therapy. Early diagnosis and treatment initiation are crucial factors in the outcome of endogenous endophthalmitis caused by Listeria monocytogenes. This possible differential diagnosis should be kept in mind while treating patients with presumable sterile hypopyon and anterior uveitis having a high intraocular pressure. A bacterial source should be considered with a prompt initiation of systemic

-rays (p<0.0001). However, three case-control studies that relied solely on information from medical records did not find evidence of an association between risk of cancer and diagnostic X-rays. Also, the risks of cancer estimated from the studies with self-reported exposures were much larger than extrapolations from higher dose studies predicted. Differential reporting by cases and controls, in the studies that used self-reporting, may account for these discrepancies. The accuracy of self-reported X-ray exposures was examined in case-control studies of thyroid cancer in Sweden and in the U.S., by comparing interview and medical record data. Results from both studies suggested that self-reporting was unreliable. There was some evidence that reporting of X-rays by controls was significantly poorer than reporting by cases, and the difference increased as the number of X-ray exposures increased. Such differential reporting could produce a spurious trend in the risk of cancer with increasing numbers of X-rays in studies based on self-reported exposures. The evidence for differential reporting, and the fact that three case-control studies based solely on medical records did not find significant excess risks, suggests that the risk of cancer from diagnostic X-rays is probably smaller than estimated by the studies that used self-reported exposures. To detect directly a risk of cancer of the size predicted from higher dose studies would require studies based on medical records with several thousand cases and controls. (author)

This study assessed the computer/mobile device screen time and eye care behavior of children and examined the roles of risk perception and parental practices. Data were obtained from a sample of 2,454 child-parent dyads recruited from 30 primary schools in Taipei city and New Taipei city, Taiwan, in 2016. Self-administered questionnaires were collected from students and parents. Fifth-grade students spend more time on new media (computer/smartphone/tablet: 16 hours a week) than on traditional media (television: 10 hours a week). The average daily screen time (3.5 hours) for these children exceeded the American Academy of Pediatrics recommendations (≤2 hours). Multivariate analysis results showed that after controlling for demographic factors, the parents with higher levels of risk perception and parental efficacy were more likely to mediate their child's eye care behavior. Children who reported lower academic performance, who were from non-intact families, reported lower levels of risk perception of mobile device use, had parents who spent more time using computers and mobile devices, and had lower levels of parental mediation were more likely to spend more time using computers and mobile devices; whereas children who reported higher academic performance, higher levels of risk perception, and higher levels of parental mediation were more likely to engage in higher levels of eye care behavior. Risk perception by children and parental practices are associated with the amount of screen time that children regularly engage in and their level of eye care behavior.
Workplace bullying a risk for permanent employees.

We tested the hypothesis that the risk of experiencing workplace bullying was greater for those employed on casual contracts compared to permanent or ongoing employees. A cross-sectional population-based telephone survey was conducted in South Australia in 2009. Employment arrangements were classified by self-report into four categories: permanent, casual, fixed-term and self-employed. Self-report of workplace bullying was modelled using multiple logistic regression in relation to employment arrangement, controlling for sex, age, working hours, years in job, occupational skill level, marital status and a proxy for socioeconomic status. Workplace bullying was reported by 174 respondents (15.2%). Risk of workplace bullying was higher for being in a professional occupation, having a university education and being separated, divorced or widowed, but did not vary significantly by sex, age or job tenure. In adjusted multivariate logistic regression models, casual workers were significantly less likely than workers on permanent or fixed-term contracts to report bullying. Those separated, divorced or widowed had higher odds of reporting bullying than married, de facto or never-married workers. Contrary to expectation, workplace bullying was more often reported by permanent than casual employees. It may represent an exposure pathway not previously linked with the more idealised permanent employment arrangement. A finer understanding of psycho-social hazards across all employment arrangements is needed, with equal attention to the hazards associated with permanent as well as casual employment. © 2012 The Authors.

Full Text Available Living in a geographically higher altitude affects oxygen availability. The possible connection between environmental factors and the development of metabolic syndrome (MetS feature is not fully understood, being the available epidemiological evidence still very limited. The aim of the present study was to evaluate the longitudinal association between altitude and incidence of MetS and each of its components in a prospective Spanish cohort, The Seguimiento Universidad de Navarra (SUN project. Our study included 6860 highly educated subjects (university graduates free from any MetS criteria at baseline. The altitude of residence was imputed with the postal code of each individual subject residence according to the data of the Spanish National Cartographic Institute and participants were categorized into tertiles. MetS was defined according to the harmonized definition. Cox proportional hazards models were used to assess the association between the altitude of residence and the risk of MetS during follow-up. After a median follow-up period of 10 years, 462 incident cases of MetS were identified. When adjusting for potential confounders, subjects in the highest category of altitude (>456 m exhibited a significantly lower risk of developing MetS compared to those in the lowest tertile (<122 m of altitude of residence [Model 2: Hazard ratio = 0.75 (95% Confidence interval: 0.58–0.97; p for trend = 0.029]. Living at geographically higher altitude was associated with a lower risk of developing MetS in the SUN project. Our findings suggest that geographical elevation may be an important factor linked to metabolic diseases.

To examine the discriminant validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) in detecting patients with cognitive impairment at higher risk for dementia at a memory clinic setting. Memory clinic patients were administered the MoCA, MMSE, and a comprehensive formal neuropsychological battery. Mild cognitive impairment (MCI) subtypes were dichotomized into two groups: single domain-MCI (sd-MCI) and multiple domain-MCI (md-MCI). Area under the receiver operating characteristic curve (ROC) analysis was used to compare the discriminatory ability of the MoCA and the MMSE. Two hundred thirty patients were recruited, of which 136 (59.1%) were diagnosed with dementia, 61 (26.5%) with MCI, and 33 (14.3%) with no cognitive impairment (NCI). The majority of MCI patients had md-MCI (n = 36, 59%). The MoCA had significantly larger AUCs than the MMSE in discriminating md-MCI from the lower risk group for incident dementia (NCI and sd-MCI) [MoCA 0.92 (95% CI, 0.86-0.98) vs. MMSE 0.84 (95% CI, 0.75-0.92), p = 0.02). At their optimal cut-off points, the MoCA (19/20) remained superior to the MMSE (23/24) in detecting md-MCI [sensitivity: 0.83 vs. 0.72; specificity: 0.86 vs. 0.83; PPV: 0.79 vs. 0.72; NPV: 0.89 vs. 0.83; correctly classified: 85.1% vs. 78.7%]. The MoCA is superior to the MMSE in the detection of patients with cognitive impairment at higher risk for incident dementia at a memory clinic setting.

Cannabis and its synthetic analogues are currently the most widely consumed illicit substances worldwide. Multiple alterations have been linked to its use, including cerebrovascular disease (CVD) or stroke, whose association with the substance has been based mainly on the hypothesis of transient vasoconstriction, which explains a large proportion of the cases reported. However, epidemiological studies have not performed an individual analysis of patients without other cardiovascular risk factors, which may limit the estimation of the risk of stroke associated with cannabis use alone. A systematic literature review was conducted through Medline, EBSCOhost, EMBASE, Lilacs, and Scielo to gather case reports published before 13 May 2016 presenting patients with a diagnosis of CVD or transient ischaemic attack, a history of cannabinoid use, and no other cardiovascular risk factors. Key words such as stroke, cerebrovascular disease, cannabis, and marijuana, among others, were used. A total of 18 case reports were selected from the 566 references found. There is a wide variety of reports of stroke associated with cannabis use in patients with no other risk factors. Noteworthy findings were presentation at young age and a strong temporal association, which place cannabis use as a potential risk factor for this population in line with the epidemiological and pathophysiological studies in this area.

The purpose of this study was to evaluate whether Asian American adolescents have higher metabolic risk from excess weight than non-Asians. Seven hundred thirty-three students, aged 14 to 19 years old, completed a school-based health screening. The 427 Asian and 306 non-Asian students were overall equivalent on age, sex, and family income. Height, weight, waist circumference, percent body fat, and blood pressure were measured. Fasting triglycerides, high- and low-density lipoproteins, glucose, and insulin levels were measured. Asian and non-Asians in lean or overweight/obesity groups were contrasted on the five factors that make up the metabolic syndrome. Asian adolescents carrying excess weight had significantly higher insulin resistance (IR), triglyceride levels, and waist-height ratios (W/H), despite a significantly lower overall BMI than corresponding non-Asians. Similarly, Asians had a stronger relationship between W/H and the degree of IR than non-Asian counterparts; 35% and 18% of the variances were explained (R 2 = 0.35, R 2 = 0.18) respectively, resulting in a significant W/H by racial group interaction (F change [1,236] = 11.56, P Asians have higher IR and triglyceride levels from excess weight than their non-Asian counterparts. One-size-fits-all public health policies targeting youth should be reconsidered and attention paid to Asian adolescents, including those with mild degrees of excess weight. © 2017 The Obesity Society.

Ecotoxicity data with high reliability and relevance are needed to guarantee the scientific quality of environmental risk assessments of pharmaceuticals. The main advantages of a more structured approach to data evaluation include increased transparency and predictability of the risk assessment process, and the possibility to use non-standard data. In this collaboration, between the research project MistraPharma and the German Federal Environment Agency, a new set of reporting and evaluation criteria is presented and discussed. The new criteria are based on the approaches in the literature and the OECD reporting requirements, and have been further developed to include both reliability and relevance of test data. Intended users are risk assessors and researchers performing ecotoxicological experiments, but the criteria can also be used for education purposes and in the peer-review process for scientific papers. This approach intends to bridge the gap between the regulator and the scientist's needs and way of work. - Highlights: → A structured approach to data evaluation increases the transparency and predictability of the risk assessment process. → A structured approach to data reporting opens up for use of data from the open scientific literature in risk assessments. → Both relevance and reliability aspects are included in the reporting and evaluation criteria. → The criteria can be used by risk assessors, by researchers, for education purposes and in the peer-review process. - The need for reporting and evaluation criteria towards a transparent and reliable use of ecotoxicity data.

Lymphedema is a potentially debilitating condition that occurs among breast cancer survivors. This study examines the incidence of self-reported lymphedema, timing of lymphedema onset, and associations between sociodemographic, clinical and lifestyle factors and lymphedema risk across racial-ethnic groups using data from a multicenter, multiethnic prospective cohort study of breast cancer survivors, the Health, Eating, Activity and Lifestyle Study. A total of 666 women diagnosed with breast cancer staged as in situ, localized or regional disease at ages 35 to 64 years were recruited through the Surveillance, Epidemiology, and End Results registries in New Mexico (non-Hispanic white and Hispanic white), Los Angeles County (black), and Western Washington (non-Hispanic white) and followed for a median of 10.2 years. We evaluated sociodemographic factors, breast cancer- and treatment-related factors, comorbidities, body mass index (BMI), hormonal factors, and lifestyle factors in relation to self-reported lymphedema by fitting Cox proportional hazards models, estimating hazard ratios (HR) and 95% confidence intervals (CI). Over the follow-up period, 190 women (29%) reported lymphedema. The median time from breast cancer diagnosis to onset of lymphedema was 10.5 months (range: 0.5 to 134.9 months). Factors independently associated with lymphedema were total/modified radical mastectomy (versus partial/less than total mastectomy; HR = 1.37, 95% CI: 1.01 to 1.85), chemotherapy (versus no chemotherapy; HR = 1.48, 95% CI: 1.09 to 2.02), no lymph nodes removed (versus ≥10 lymph nodes removed; HR = 0.17, 95% CI: 0.08 to 0.33), pre-diagnostic BMI ≥30 kg/m2 (versus BMI race/ethnicity showed that hypertension and chemotherapy were lymphedema risk factors only for black women. Breast cancer patients who have undergone extensive surgery or extensive lymph node dissection, or who have a higher BMI should be closely monitored for detection and treatment of lymphedema. Further

Full Text Available Infection due to prostate biopsy afflicted more than 5% of patients and is the most common reason for hospitalization. A large series from US SEER-Medicare reported that men undergoing biopsy were 2.26 times more likely to be hospitalized for infectious complications within 30 days compared with randomly selected controls. The factors predicting a higher susceptibility to infection remain largely unknown but some authors have higlighted in the etiopathogenesis the importance of the augmented prevalence of ciprofloxacin resistant variant of bacteria in the rectum flora. We present one case of sepsis after transrectal prostate biopsy in a patient with history of pancreatic surgery. Based on our experience patients candidated to prostate biopsy with transrectal technique with history of recent major surgery represent an high risk category for infective complication. Also major pancreatic surgery should be consider an high risk category for infection. A transperineal approach and preventive measures (such as rectal swab should be adopted to reduce biopsy driven infection.

Rapid growth in unconventional oil and gas (UOG) has produced jobs, revenue, and energy, but also concerns over spills and environmental risks. We assessed spill data from 2005 to 2014 at 31 481 UOG wells in Colorado, New Mexico, North Dakota, and Pennsylvania. We found 2-16% of wells reported a spill each year. Median spill volumes ranged from 0.5 m 3 in Pennsylvania to 4.9 m 3 in New Mexico; the largest spills exceeded 100 m 3 . Seventy-five to 94% of spills occurred within the first three years of well life when wells were drilled, completed, and had their largest production volumes. Across all four states, 50% of spills were related to storage and moving fluids via flowlines. Reporting rates varied by state, affecting spill rates and requiring extensive time and effort getting data into a usable format. Enhanced and standardized regulatory requirements for reporting spills could improve the accuracy and speed of analyses to identify and prevent spill risks and mitigate potential environmental damage. Transparency for data sharing and analysis will be increasingly important as UOG development expands. We designed an interactive spills data visualization tool ( http://snappartnership.net/groups/hydraulic-fracturing/webapp/spills.html ) to illustrate the value of having standardized, public data.

Full Text Available OBJECTIVES: To report the incidence of objective and subjective neurosensory disturbance (NSD after orthognathic surgery in a major orthognathic centre in Hong Kong, and to investigate the risk factors that contributed to the incidence of NSD after orthognathic surgery. MATERIALS AND METHODS: A retrospective cross-sectional study on NSD after orthognathic surgery in a local major orthognathic centre. Patients who had bimaxillary orthognathic surgery reviewed at post-operative 6 months, 12 months or 24 months were recruited to undergo neurosensory tests with subjective and 3 objective assessments. Possible risk factors of NSD including subjects' age and gender, surgical procedures and surgeons' experience were analyzed. RESULTS: 238 patients with 476 sides were recruited. The incidences of subjective NSD after maxillary procedures were 16.2%, 13% and 9.8% at post-operative 6 months, 12 months and 24 months, respectively; the incidences of subjective NSD after mandibular procedures were 35.4%, 36.6% and 34.6% at post-operative 6 months, 12 months and 24 months, respectively. Increased age was found to be a significant risk factor of NSD after orthognathic surgery at short term (at 6 months and 12 months but not at 24 months. SSO has a significantly higher risk of NSD when compared to VSSO. SSO in combination with anterior mandibular surgery has a higher risk of NSD when compared to VSSO in combination with anterior mandibular surgery or anterior mandibular surgery alone. Gender of patients and surgeons' experience were not found to be risk factors of NSD after orthognathic surgery. CONCLUSION: The incidence of NSD after maxillary and mandibular orthognathic procedures at post-operative 6 months, 12 months and 24 months was reported. Increased age was identified as a risk factor of short term post-operative NSD but not in long term (24 months or more. Specific mandibular procedures were related to higher incidence of NSD after orthognathic surgery.
Mandatory Reporting of Human Trafficking: Potential Benefits and Risks of Harm.
English, Abigail
2017-01-01
Human trafficking, including both sex and labor trafficking, has profound consequences for the safety, health, and well-being of victims and survivors. Efforts to address human trafficking through prevention, protection, and prosecution are growing but remain insufficient. Mandatory reporting has the potential to bring victims and survivors to the attention of social service and law enforcement agencies but may discourage trafficked persons from seeking help, thereby limiting the ability of health care professionals to establish trust and provide needed care. States' experience in implementing child abuse laws can be useful in assessing the potential risks and benefits of mandatory reporting of human trafficking. © 2017 American Medical Association.

Risk factors for fractures in the elderly.
Jacqmin-Gadda, H; Fourrier, A; Commenges, D; Dartigues, J F
1998-07-01
We report the results of a 5-year prospective cohort study of risk factors for fractures, including drinking fluoridated water, in a cohort of 3,216 men and women aged 65 years and older. We studied risk factors for hip fracture and fractures at other locations separately. We found a higher risk of hip fractures for subjects exposed to fluorine concentrations over 0.11 mg per liter but without a dose-effect relation (odds ratio (OR) = 3.25 for a concentration of 0.11-0.25 mg per liter; OR = 2.43 for > or = 0.25 mg per liter]. For higher thresholds (0.7 and 1 mg per liter), however, the OR was less than 1. We found no association between fluorine and non-hip fractures. Non-hip fractures were associated with polymedication rather than with specific drug use, whereas fracture was associated with polymedication and use of anxiolytic and antidepressive drugs. Subjects drinking spirits every day were more likely to have hip fractures. Tobacco consumption increased the risk for non-hip fractures.

'The goal of this report is to establish a protocol for assessing risks to non-human populations exposed to environmental stresses typically found on many DOE sites. The authors think that they can achieve this by using novel biological dosimeters in controlled, manipulative dose/effects experiments, and by coupling changes in metabolic rates and energy allocation patterns to meaningful population response variables (such as age-specific survivorship, reproductive output, age at maturity and longevity). This research is needed to determine the relevancy of sublethal cellular damage to the performance of individuals and populations exposed to chronic, low-level radiation, and radiation with concomitant exposure to chemicals. They believe that a scientifically defensible endpoint for measuring ecological risks can only be determined once its understood the extent to which molecular damage from contaminant exposure is detrimental at the individual and population levels of biological organization. The experimental facility will allow them to develop a credible assessment tool for appraising ecological risks, and to evaluate the effects of radionuclide/chemical synergisms on non-human species. This report summarizes work completed midway of a 3-year project that began in November 1996. Emphasis to date has centered on three areas: (1) developing a molecular probe to measure stable chromosomal aberrations known as reciprocal translocations, (2) constructing an irradiation facility where the statistical power inherent in replicated mesocosms can be used to address the response of non-human organisms to exposures from low levels of radiation and metal contaminants, and (3) quantifying responses of organisms living in contaminated mesocosms and field sites.'

In rural Bangladesh, more than 75% of all births occur at home in the absence of skilled birth attendants. Population-based data are lacking on the burden and risk factors for obstetric complications in settings with low rates of institutional delivery. We sought to describe the prevalence of reported complications and to analyze risk factors for obstetric complications and near misses, using data from a representative, rural setting of Bangladesh. This study utilized existing data on 42,214 pregnant women enrolled in a micronutrient supplementation cohort trial between 2007 and 2011 in rural northwest Bangladesh. Based on self-report of complications, women were categorized as having obstetric complications, near misses, or non-complicated pregnancies using definitions modified from the World Health Organization. Multivariable multinomial regression was used to analyze the association of biological, socioeconomic, and psychosocial variables with obstetric complications or near misses. Of enrolled women, 25% (n = 10,380) were classified as having at least one obstetric complication, 2% (n = 1,004) with reported near misses, and 73% (n = 30,830) with non-complicated pregnancies. Twelve percent (n = 5,232) reported hemorrhage and 8% (n = 3,259) reported sepsis. Of the 27,241 women with live births or stillbirths, 11% (n = 2,950) reported obstructed labor and 1% (n = 328) reported eclampsia. Biological risk factors including women's age less than 18 years (Relative Risk Ratio [RRR] 1.26 95%CI:1.14-1.39) and greater than 35 years (RRR 1.23 95%CI:1.09-1.38), history of stillbirth or miscarriage (RRR 1.15 95%CI:1.07-1.22), and nulliparity (RRR 1.16 95%CI:1.02-1.29) significantly increased the risk of obstetric complications. Neither partner wanting the pregnancy increased the risk of obstetric complications (RRR 1.33 95%CI:1.20-1.46). Mid-upper arm circumference <21.5 cm increased the risk of hemorrhage and sepsis. These analyses indicate a high burden of obstetric
Risk factors for interpersonal conflicts at work.

The main goal of this study was to identify work-related risk factors for the onset of interpersonal conflicts at work. Longitudinal data from the Maastricht Cohort Study on "fatigue at work" (N=9241) were used. After the respondents who reported an interpersonal conflict at baseline were excluded, logistic regression analyses were used to determine the role of several work-related risk factors at baseline in the onset of a conflict with coworkers or supervisors after 1 year of follow-up. Higher psychological job demands, higher levels of role ambiguity, the presence of physical demands, higher musculoskeletal demands, a poorer physical work environment, shift work, overtime, and higher levels of job insecurity significantly predicted the onset of both a coworker conflict and a supervisor conflict. Higher levels of coworker and supervisor social support, more autonomy concerning the terms of employment, good overall job satisfaction, monetary gratification, and esteem reward significantly protected against the onset of both a coworker conflict and a supervisor conflict. Higher levels of decision latitude and more career opportunities also significantly protected against the onset of a supervisor conflict. Several factors in the work environment were related to the onset of interpersonal conflicts at work. Given the rather serious consequences of interpersonal conflicts at work with respect to health and well-being, the observed risk factors can serve as a starting point for effective prevention and intervention strategies in the workplace.

The purpose of this study was to examine the relationships among risky driving attitudes, self-perceptions as a risky driver, playing of "drive'em up" (which rewarded players for frequent traffic and other violations) and "circuit" racing video games as well as self-reported risky driving through a web-based survey of car and racing club members in relation to a socio-cognitive model of the effects of racing video game playing. An Internet questionnaire was developed and included: (1) self-perceptions as a risky driver scales (Driver Thrill Seeking and Competitive Attitude Toward Driving); (2) attitudes regarding street racing; (3) street racing video game playing, and (4) self-reported risky driving (Risk-Taking Driving Scale). A sequential logistic regression was performed entering age and driving exposure as control variables in the first block, self-perceptions as a risky driver in the second block, attitudes in the third block and playing "drive'em up" and "circuit" racing games in the last block to examine their effects on self-reported risk-taking driving. A total of 503 survey respondents were included in the analyses and only 20% reported any risk-taking driving. Higher score on the Competitive Attitude Toward Driving Scale, more positive attitudes toward street racing, and more frequent reported playing of "drive'em up" video games were associated with higher odds on the self-reported Risk-Taking Driving Scale. However, the Driver Thrill Seeking Scale and "circuit" video game playing failed to predict self-reported risk-taking driving. Self-perceptions as a risky driver, positive attitudes toward risky driving and "drive'em up" street-racing games, but not "circuit" racing games, are associated with increased risk-taking driving. These findings are congruent with experimental studies in which games that reward driving violations increased risk taking, suggesting that risk taking may be a function of type of street racing game played by affecting self

The Risk Assessment Review Group was organized by the U.S. Nuclear Regulatory Commission on July 1, 1977, with four elements to its charter: clarify the achievements and limitations of WASH-1400, the ''Rasmussen Report''; assess the peer comments thereon, and responses to those comments; study the present state of such risk assessment methodology; and recommend to the Commission how (and whether) such methodology can be used in the regulatory and licensing process. Areas of study include: risk assessment methodologies; statistical issues; completeness; the data base; and the WASH-1400 assessment of the damage to human health from radiation after a postulated accident. Specific items discussed include: Browns Ferry; common cause failure; human factors; format and scrutability; the peer review process; earthquakes; risk perception; allegations by UCS concerning WASH-1400 treatment of quality assurance and quality control; current role of probabilistic methods in the regulatory process; acts of violence; ATWS; influence of design defects in quality assurance failures; and calculation of population doses from given releases of radionuclides
Higher prices, higher quality? Evidence from German nursing homes.
Herr, Annika; Hottenrott, Hanna
2016-02-01
This study investigates the relationship between prices and quality of 7400 German nursing homes. We use a cross section of public quality reports for all German nursing homes, which had been evaluated between 2010 and 2013 by external institutions. Our analysis is based on multivariate regressions in a two stage least squares framework, where we instrument prices to explain their effect on quality controlling for income, nursing home density, demographics, labour market characteristics, and infrastructure at the regional level. Descriptive analysis shows that prices and quality do not only vary across nursing homes, but also across counties and federal states and that quality and prices correlate positively. Second, the econometric analysis, which accounts for the endogenous relation between negotiated price and reported quality, shows that quality indeed positively depends on prices. In addition, more places in nursing homes per people in need are correlated with both lower prices and higher quality. Finally, unobserved factors at the federal state level capture some of the variation of reported quality across nursing homes. Our results suggest that higher prices increase quality. Furthermore, since reported quality and prices vary substantially across federal states, we conclude that the quality and prices of long-term care facilities may well be compared within federal states but not across.

Small modular reactors (SMRs) generally include reactors with electric output of ~350 MWe or less (this cutoff varies somewhat but is substantially less than full-size plant output of 700 MWe or more). Advanced SMRs (AdvSMRs) refer to a specific class of SMRs and are based on modularization of advanced reactor concepts. AdvSMRs may provide a longer-term alternative to traditional light-water reactors (LWRs) and SMRs based on integral pressurized water reactor concepts currently being considered. Enhancing affordability of AdvSMRs will be critical to ensuring wider deployment. AdvSMRs suffer from loss of economies of scale inherent in small reactors when compared to large (~greater than 600 MWe output) reactors. Some of this loss can be recovered through reduced capital costs through smaller size, fewer components, modular fabrication processes, and the opportunity for modular construction. However, the controllable day-to-day costs of AdvSMRs will be dominated by operation and maintenance (O&M) costs. Technologies that help characterize real-time risk are important for controlling O&M costs. Risk monitors are used in current nuclear power plants to provide a point-in-time estimate of the system risk given the current plant configuration (e.g., equipment availability, operational regime, and environmental conditions). However, current risk monitors are unable to support the capability requirements listed above as they do not take into account plant-specific normal, abnormal, and deteriorating states of active components and systems. This report documents technology developments that are a step towards enhancing risk monitors that, if integrated with supervisory plant control systems, can provide the capability requirements listed and meet the goals of controlling O&M costs. The report describes research results from an initial methodology for enhanced risk monitors by integrating real-time information about equipment condition and POF into risk monitors.

To compare the metabolic, anthropometric, arterial blood pressure, and muscle strength parameters of elderly women with and without metabolic syndrome. A case-control study with 27 (67.3±4.8 years of age, 31.0±5.0kg/m{sup 2}) elderly women with metabolic syndrome and 33 (68.8±5.6 years of age, 27.2±5.3kg/m{sup 2}) sedentary control elderly women. They were submitted to an evaluation of body composition by means of dual-energy X-ray absorptiometry and muscle strength testing with 10 maximal repetitions of knee extension. When compared to the elderly women without metabolic syndrome, those with the metabolic syndrome had higher levels for body mass (72.2±13.5 versus 63.4±14.6kg, p=0.03), body mass index (31.0±5.0 versus 27.2±5.3kg/m{sup 2,} p=0.007), fat mass (30.9±9.9 versus 24.4±8.5kg, p=0.01), systolic arterial pressure (125.1±8.2 versus 119.3±8.7mmHg, p=0.01), diastolic arterial pressure (75.5±6.9 versus 71.4±6.7mmHg, p=0.03), mean arterial pressure (92.5±6.2 versus 87.1±6.7mmHg, p=0.004), blood glucose (103.8±19.1 versus 91.1±5.9mg/dL, p=0.001), triglycerides (187.1±70.2 versus 116.3±36.7mg/dL, p=0.001), and creatine kinase (122.6±58.6 versus 89.8±32.5U/L, p=0.01); lower levels were found for fat-free mass (55.9±5.8 versus 59.3±6.7%; p=0.05), HDL-C (40.7±5.0 versus 50.5±10.1mg/dL, p=0.001), and relative muscle strength (0.53±0.14 versus 0.62±0.12, p=0.01). Elderly women with metabolic syndrome have a higher cardiovascular risk and less relative muscle strength when compared to those without metabolic syndrome. Relative muscle strength may be related to the cardiovascularr risk factors of the metabolic syndrome.

to assess reproducibility of self-reported exposure to ergonomic hazards for the upper limbs, measured through a questionnaire based on a diffused checklist for the assessment of ergonomic risk (OCRA) in a sample of mechanical assemblers of an automotive industry. cross-sectional study; reproducibility was assessed as interrater agreement of a composite index of ergonomic risk, estimated through the intraclass correlation coefficient (ICC). 58 mechanical assemblers, working in 29 twin areas, characterised by same work stations and tasks. composite index of ergonomic risk for the upper limbs. reproducibility of the ergonomic index was high in the overall sample (ICC: 0.81) and it was higher for the twin areas employing same-gender workers (ICC: 0.96), compared to those with workers of the opposite gender (ICC: 0.66). these results indicate that a questionnaire measuring with a great detail the exposure to the main ergonomic risk factors for the upper limbs, as the one based on the OCRA checklist used for this study, would allow to obtain a highly reproducible ergonomic index. If its validity against the corresponding observational checklist will be found elevated by future studies, this questionnaire may represent a useful tool for a preliminary assessment of workers' exposure to ergonomic hazards for the upper limbs.

Background Household cleaning and pesticide products may contribute to breast cancer because many contain endocrine disrupting chemicals or mammary gland carcinogens. This population-based case-control study investigated whether use of household cleaners and pesticides increases breast cancer risk. Methods Participants were 787 Cape Cod, Massachusetts, women diagnosed with breast cancer between 1988 and 1995 and 721 controls. Telephone interviews asked about product use, beliefs about breast cancer etiology, and established and suspected breast cancer risk factors. To evaluate potential recall bias, we stratified product-use odds ratios by beliefs about whether chemicals and pollutants contribute to breast cancer; we compared these results with odds ratios for family history (which are less subject to recall bias) stratified by beliefs about heredity. Results Breast cancer risk increased two-fold in the highest compared with lowest quartile of self-reported combined cleaning product use (Adjusted OR = 2.1, 95% CI: 1.4, 3.3) and combined air freshener use (Adjusted OR = 1.9, 95% CI: 1.2, 3.0). Little association was observed with pesticide use. In stratified analyses, cleaning products odds ratios were more elevated among participants who believed pollutants contribute "a lot" to breast cancer and moved towards the null among the other participants. In comparison, the odds ratio for breast cancer and family history was markedly higher among women who believed that heredity contributes "a lot" (OR = 2.6, 95% CI: 1.9, 3.6) and not elevated among others (OR = 0.7, 95% CI: 0.5, 1.1).

This report supports the overall assessment by Oak Ridge National Laboratory of actinide partitioning and transmutation by providing an analysis of the long-term risks associated with the terminal storage of wastes from a fuel cycle which incorporates partitioning and transmutation (P-T) and wastes from a cycle which does not. The system model and associated computer code, called AMRAW (Assessment Method for Radioactive Waste), are used for the analysis and are applied to the Los Medanos area in southeastern New Mexico. Because a conservative approach is used throughout, calculated results are believed to be consistently higher than reasonable expectations from actual disruptive incidents at the site and therefore are not directly suited for comparison with other analyses of the particular geologic location. The assessment is made with (1) the probabilistic, or risk, mode that uses combinations of reasonable possible release incidents with their probability of occurrence distributed and applied throughout the assessment period, and (2) the consequence mode that forces discrete release events to occur at specific times. An assessment period of 1 million years is used. The principal results are: (1) In all but the expulsive modes, 99 Tc and 129 I completely dominate cumulative effects based on their transport to man through leaching and movement with groundwater, effecting about 33,000 health effects (deaths) over the 1 million years; (2) P-T has only limited effectiveness in reducing long-term risk from a radionuclide waste repository under the conditions studied, and such effectiveness is essentially confined to the extremely unlikely (probability of occurrence 10 -12 /year) expulsive events; (3) Removal or immobilization of 99 Tc and 129 I might provide benefits sufficiently tangible to warrant special consideration

We outline the construction of differential invariants for higher-rank tensors. In section 2 we outline the general method for the construction of differential invariants. A first result is that the simplest tensor differential invariant contains derivatives of the same order as the rank of the tensor. In section 3 we review the construction for the first-rank tensors (vectors) and second-rank tensors (metrics). In section 4 we outline the same construction for higher-rank tensors. (author)

INTRODUCTION Reporting surgeons' outcomes has recently been introduced in the UK. This has the potential to result in surgeons becoming risk averse. The aim of this study was to investigate whether reporting outcomes for abdominal aortic aneurysm (AAA) surgery impacts on the number and risk profile (level of fitness) of patients offered elective treatment. METHODS Publically available National Vascular Registry data were used to compare the number of AAAs treated in those centres across the UK that reported outcomes for the periods 2008-2012, 2009-2013 and 2010-2014. Furthermore, the number and characteristics of patients referred for consideration of elective AAA repair at a single tertiary unit were analysed yearly between 2010 and 2014. Clinic, casualty and theatre event codes were searched to obtain all AAAs treated. The results of cardiopulmonary exercise testing (CPET) were assessed. RESULTS For the 85 centres that reported outcomes in all three five-year periods, the median number of AAAs treated per unit increased between the periods 2008-2012 and 2010-2014 from 192 to 214 per year (p=0.006). In the single centre cohort study, the proportion of patients offered elective AAA repair increased from 74% in 2009-2010 to 81% in 2013-2014, with a maximum of 84% in 2012-2013. The age, aneurysm size and CPET results (anaerobic threshold levels) for those eventually offered elective treatment did not differ significantly between 2010 and 2014. CONCLUSIONS The results do not support the assumption that reporting individual surgeon outcomes is associated with a risk averse strategy regarding patient selection in aneurysm surgery at present.

Full Text Available Alzheimer’s disease (AD risk genes alter brain structure and function decades before disease onset. Apolipoprotein E (APOE is the strongest known genetic risk factor for Alzheimer’s disease, and a related gene, apolipoprotein J (APOJ, also affects disease risk. However, the extent to which these genes affect brain structure in young adults remains unclear. Here, we report that AD risk alleles of these two genes, APOE-ε4 and APOJ-C, cumulatively alter brain volume in young adults. Using voxel-based morphometry in 57 individuals, we examined the entorhinal cortex, one of the earliest brain regions affected in AD pathogenesis. APOE-ε4 carriers exhibited higher right entorhinal cortex volume compared to non-carriers. Interestingly, APOJ-C risk genotype was associated with higher bilateral entorhinal cortex volume in non-APOE-ε4 carriers. To determine the combined disease risk of APOE and APOJ status per subject, we used cumulative odds ratios as regressors for volumetric measurements. Higher disease risk corresponded to greater right entorhinal cortex volume. These results suggest that, years before disease onset, two key AD genetic risk factors may exert influence on the structure of a brain region where AD pathogenesis takes root.

However, the extent to which these genes affect brain structure in young adults remains unclear. Here, we report that AD risk alleles of these two genes, APOE-ε4 and APOJ-C, cumulatively alter brain volume in young adults. Using voxel-based morphometry (VBM) in 57 individuals, we examined the entorhinal cortex, one of the earliest brain regions affected in AD pathogenesis. Apolipoprotein E-ε4 carriers exhibited higher right entorhinal cortex volume compared to non-carriers. Interestingly, APOJ-C risk genotype was associated with higher bilateral entorhinal cortex volume in non-APOE-ε4 carriers.

Women undergoing vascular surgery have higher morbidity and mortality. Our study explores gender-based differences in patient-centered outcomes such as readmission, length of stay (LOS), and discharge destination (home vs nonhome facility) in aortic aneurysm surgery. Patients were identified from the American College of Surgeons National Surgical Quality Improvement Project database (2011-2013) undergoing abdominal, thoracic, and thoracoabdominal aortic aneurysms (N = 17,763), who were discharged and survived their index hospitalization. The primary outcome was unplanned readmission, and secondary outcomes were discharge to a nonhome facility, LOS, and reasons for unplanned readmission. Univariate, multivariate, and stratified analyses based on gender and discharge destination were used. Overall, 1541 patients (8.7%) experienced an unplanned readmission, with a significantly higher risk in women vs men (10.8% vs 8%; P women compared with men persisted in multivariate analysis after controlling for covariates (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.05-1.4). Similarly, the rate of discharge to a nonhome facility was nearly double in women compared with men (20.6% vs 10.7%; P women compared with men occurred in patients who were discharged home (OR, 1.2; 95% CI, 1.02-1.4) but not in those who were discharged to a nonhome facility (OR, 1.06; 95% CI, 0.8-1.4). Significant differences in LOS were seen in patients who were discharged home. No gender differences were found in reasons for readmission with the three most common reasons being thromboembolic events, wound infections, and pneumonia. Gender disparity exists in the risk of unplanned readmission among aortic aneurysm surgery patients. Women who were discharged home have a higher likelihood of unplanned readmission despite longer LOS than men. These data suggest that further study into the discharge planning processes, social factors, and use of rehabilitation services is needed for women

Full Text Available The objective of this second part of a two-phased study was to explorethe predictive power of quantitative risk analysis (QRA method andprocess within Higher Education Institution (HEI. The method and process investigated the use impact analysis via Nicholas risk model and Bayesian analysis, with a sample of hundred (100 risk analysts in a historically black South African University in the greater Eastern Cape Province.The first findings supported and confirmed previous literature (KingIII report, 2009: Nicholas and Steyn, 2008: Stoney, 2007: COSA, 2004 that there was a direct relationship between risk factor, its likelihood and impact, certiris paribus. The second finding in relation to either controlling the likelihood or the impact of occurrence of risk (Nicholas risk model was that to have a brighter risk reward, it was important to control the likelihood ofoccurrence of risks as compared with its impact so to have a direct effect on entire University. On the Bayesian analysis, thus third finding, the impact of risk should be predicted along three aspects. These aspects included the human impact (decisions made, the property impact (students and infrastructural based and the business impact. Lastly, the study revealed that although in most business cases, where as business cycles considerably vary dependingon the industry and or the institution, this study revealed that, most impacts in HEI (University was within the period of one academic.The recommendation was that application of quantitative risk analysisshould be related to current legislative framework that affects HEI.

United States Army military police (MP) training is a 19-week course designed to introduce new recruits to basic soldiering skills, Army values and lifestyle, and law enforcement skills and knowledge. The present investigation examined injury rates and injury risk factors in MP training. At the start of training, 1,838 male and 553 female MP recruits were administered a questionnaire containing items on date of birth, height, weight, tobacco use, prior physical activity, injury history, and menstrual history. Injuries during training were obtained from electronic medical records and the training units provided data on student graduation and attrition. Successfully graduating from the course were 94.3% of the men and 83.7% of the women. Experiencing at least one injury during training were 34.2% of the men and 66.7% of the women (risk ratio (women/men) = 1.95, 95% confidence interval = 1.79-2.13). Recruits were at higher injury risk if they reported that they were older, had smoked in the past, or had performed less frequent exercise or sports prior to MP training. Men were at higher injury risk if they reported a prior injury and women were at higher risk if they reported missing at least six menstrual cycles in the last year or had previously been pregnant. The present investigation was the first to identify injury rates and identify specific factors increasing injury risk during MP training.

A Partitioning-Transmutation (PT) fuel cycle is being compared to a Reference cycle employing conventional fuel-material recovery methods. The PT cycle uses enhanced recovery methods so that most of the long-lived actinides are recycled to nuclear power plants and transmuted thereby reducing the waste toxicity. This report compares the two fuel cycles on the basis of the short-term radiological and nonradiological risks. The accidental radiological risk to the public is analyzed by estimating the probabilities of sets of accidents; the consequences are calculated using the risk, which is RAC code. Routine radiological risks to the public are estimated from the calculated release amounts, also using the CRAC code. Radiological occupational risks are determined from prior experience, projected standards, and estimates of accident risk. Nonradiological risks are calculated from the number of personnel involved, historical experience, and epidemiological studies. Result of this analysis is that the short-term risk of PT is 2.9 times greater than that of the Reference cycle, primarily due to the larger amount of industry. The nonradiological risk which is about 150 times greater than the radiological risk. If the radiological risk is consdered alone, the ratio of PT to Reference risk is 3, composed as follows: radiological operations affecting the public 5, radiological operations affecting the workers 1.7, and radiological accidents affecting the public 1.4, all in the order of decreasing risk. The absolute risk as estimated for the fuel cycle portions considered in this report is 0.91 fatality/GWe-year for the PT cycle and 0.34 fatality/GWe-year for the reference cycle; this compares with 1.5 for nuclear and 150 for coal. All of the risks assumed here are associated with the production of one billion watts of electricity (GWe) per year

There have been various attempts to assess endometrial lesions on cytological material obtained via direct endometrial sampling. The majority of efforts focus on the description of cytological criteria that lead to classification systems resembling histological reporting formats. These systems have low reproducibility, especially in cases of atypical hyperplasia and well differentiated carcinomas. Moreover, they are not linked to the implied risk of malignancy. The material was collected from women examined at the outpatient department of four participating hospitals. We analyzed 866 consecutive, histologically confirmed cases. The sample collection was performed using the EndoGyn device, and processed via Liquid Based Cytology, namely ThinPrep technique. The diagnostic categories and criteria were established by two cytopathologists experienced in endometrial cytology; performance of the proposed reporting format was assessed on the basis of histological outcome; moreover, the implied risk of malignancy was calculated. The proposed six diagnostic categories are as follows: (i) nondiagnostic or unsatisfactory; (ii) without evidence of hyperplasia or malignancy; (iii) atypical cells of endometrium of undetermined significance; (iv) atypical cells of endometrium of low probability for malignancy; (v) atypical cells of endometrium of high probability for malignancy; and (vi) malignant. The risk of malignancy was 1.42% ± 0.98%, 44.44% ± 32.46% (nine cases), 4.30% ± 4.12%, 89.80% ± 8.47%, and 97.81% ± 2.45%, respectively. We propose a clinically oriented classification scheme consisting of diagnostic categories with well determined criteria. Each diagnostic category is linked with an implied risk of malignancy; thus, clinicians may decide on patient management and eventually reduce unnecessary interventional diagnostic procedures. Diagn.

Adolescent girls and young women (AGYW) in sub-Saharan Africa have high HIV prevalence and incidence. We sought to understand which HIV risk factors individually and in combination contribute to risk, and whether these factors are associated with HIV worry and risk perception. This study is ongoing at 4 public health centers in Lilongwe, Malawi (2016-2017). AGYW of 15-24 years old were recruited to participate in a study assessing 4 models of service delivery. At each health center, participants completed a baseline survey assessing socioeconomic, behavioral, biomedical, and partnership characteristics; self-reported HIV status; and, if HIV-uninfected, HIV risk perception (high versus low or none) and HIV worry (any versus none). We analyzed associations between baseline characteristics and HIV prevalence, risk perception, and worry. Among 1000 AGYW, median age was 19 years (IQR: 17-21). Thirty-three participants reported being HIV-infected. Fifteen characteristics were associated with HIV infection. Having more risk factors was associated with higher HIV prevalence (≤4 factors, 0.5%; 5-8 factors, 6%; >8 factors, 21%). Having more risk factors was also associated with higher risk perception (P risk factors, 52% did not consider themselves to be at high risk and 21% did not report any HIV worry. Most AGYW perceive little risk of HIV acquisition, even those at highest risk. As a critical gap in the HIV prevention cascade, accurate risk perception is needed to tailor effective and sustained combination prevention strategies for this vulnerable population.

Gene expression profiling (GEP) is increasingly used in the rapidly evolving field of personalized medicine. We sought to evaluate the association between GEP-assessed of breast cancer recurrence risk and patients’ well-being. Participants were Dutch women from 10 hospitals being treated for early stage breast cancer who were enrolled in the MINDACT trial (Microarray In Node-negative and 1 to 3 positive lymph node Disease may Avoid ChemoTherapy). As part of the trial, they received a disease recurrence risk estimate based on a 70-gene signature and on standard clinical criteria as scored via a modified version of Adjuvant! Online. /Women completed a questionnaire 6–8 weeks after surgery and after their decision regarding adjuvant chemotherapy. The questionnaire assessed perceived understanding, knowledge, risk perception, satisfaction, distress, cancer worry and health-related quality of life (HRQoL), 6–8 weeks after surgery and decision regarding adjuvant chemotherapy. Women (n = 347, response rate 62%) reported high satisfaction with and a good understanding of the GEP information they received. Women with low risk estimates from both the standard and genomic tests reported the lowest distress levels. Distress was higher predominately among patients who had received high genomic risk estimates, who did not receive genomic risk estimates, or who received conflicting estimates based on genomic and clinical criteria. Cancer worry was highest for patients with higher risk perceptions and lower satisfaction. Patients with concordant high-risk profiles and those for whom such profiles were not available reported lower quality of life. Patients were generally satisfied with the information they received about recurrence risk based on genomic testing. Some types of genomic test results were associated with greater distress levels, but not with cancer worry or HRQoL. ISRCTN: http://www.controlled-trials.com/ISRCTN18543567/MINDACT
Child maltreatment 2002: recognition, reporting and risk.
Johnson, Charles Felzen
2002-10-01
Child abuse is a major cause of morbidity and mortality in the USA and in all other countries which have studied its incidence. It is the second leading cause of death of children in the USA. To decrease the incidence of child abuse and improve the welfare of children there must be international efforts to recognize, and report child abuse and to decrease those risk factors, which place children in jeopardy. In the USA, reports of child maltreatment have decreased each year since 1994 after nearly two decades of increase. The increase was associated with the passage of laws that mandated reporting child maltreatment and increased recognition of maltreatment. Several theories have been proposed to explain the decrease. These include: improved economy with decreased caretaker stress and more vulnerable children in day-care, imprisonment of offenders, treatment of victims to prevent reactive abuse, decreased use of corporal punishment, earlier recognition and reporting, prevention programs including home visitors and less corporal punishment in schools. If early recognition is to occur there must be clearly defined and uniform laws that define abuse and the significant consequences to mandated reporters for failure to report. The laws must be concise, understandable and contain medically based definitions of abuse. A bruise should be considered a significant injury. The use of an instrument on a child, for any reason should be reportable as abusive. Society must be taught that a child's head and its contents are particularly susceptible to trauma. Heads should not be slapped, shaken, or struck. The purpose of a report of suspect maltreatment should be to obtain services for families. Without proper services, abuse will reoccur and victims will become victimizers. Any sexual act, including pornography, involving a child who is unable to give consent constitutes reportable sexual abuse. Recognition of what constitutes abuse would be simplified if all countries adopted

Telomere length is considered as a biological marker for aging. It is expected that telomeres shorten with age and with conditions associated with oxidative stress and inflammation. Both are present in patients with chronic kidney disease (CKD) who have a very high cardiovascular risk. We investigated whether CKD duration is associated with relative telomere length (RTL) in 4802 patients from the German Chronic Kidney Disease (GCKD) study. We measured RTL in each sample in quadruplicates using a quantitative polymerase chain reaction (qPCR). We observed a U-shaped association of RTL with CKD duration: the longest RTL was found in those 339 patients who reported the shortest disease duration (study these surprising results have to be considered with caution and as hypothesis-generating. Whether the longer RTL in patients with long-lasting disease is caused by an activation of telomerase to counteract the shortening of RTL due to oxidative stress and inflammation or whether they are caused by a survival bias needs to be investigated in longitudinal studies. Our data are in support of a higher plasticity of shortening and elongations of RTL as until recently anticipated. Copyright © 2015 Elsevier Inc. All rights reserved.
Risk Factors for Gout and Prevention: A Systematic Review of the Literature

Purpose Our objective was to perform a systematic review of risk factors and prevention of gout. We searched Medline for fully published reports in English using keywords including but not limited to “gout”, “epidemiology”, “primary prevention”, “secondary prevention”, “risk factors’. Data from relevant articles meeting inclusion criteria was extracted using standardized forms. Main Findings Of the 751 titles and abstracts, 53 studies met the criteria and were included in the review. Several risk factors were studied. Alcohol consumption increased the risk of incident gout, especially beer and hard liquor. Several dietary factors increased the risk of incident gout, including meat intake, seafood intake, sugar sweetened soft drinks, and consumption of foods high in fructose. Diary intake, folate intake and coffee consumption were each associated with a lower risk of incident gout and in some cases a lower rate of gout flares. Thiazide and loop diuretics were associated with higher risk of incident gout and higher rate of gout flares. Hypertension, renal insufficiency, hypertriglyceridemia, hypercholesterolemia, hyperuricemia, diabetes, obesity and early menopause were each associated with a higher risk of incident gout and/or gout flares. Summary Several dietary risk factors for incident gout and gout flares are modifiable. Prevention and optimal management of comorbidities is likely to decreased risk of gout. Research in preventive strategies for the treatment of gout is needed. PMID:21285714

The Good Behavior Game (GBG) is a universal classroom-based preventive intervention directed at reducing early aggressive, disruptive behavior and improving children's social adaptation into the classroom. The GBG is one of the few universal preventive interventions delivered in early elementary school that has been shown to reduce the risk for future suicide attempts. This paper addresses one potential mechanism by which the GBG lowers the risk of later suicide attempt. In this study, we tested whether the GBG, by facilitating social adaptation into the classroom early on, including the level of social preference by classmates, thereby lowers future risk of suicide attempts. The measure of social adaptation is based on first and second grade peer reports of social preference ("which children do you like best?"; "which children don't you like?"). As part of the hypothesized meditational model, we examined the longitudinal association between childhood peer social preference and the risk of future suicide attempt, which has not previously been examined. Data were from an epidemiologically based randomized prevention trial, which tested the GBG among two consecutive cohorts of first grade children in 19 public schools and 41 classrooms. Results indicated that peer social preference partially mediated the relationship between the GBG and the associated reduction of risk for later suicide attempts by adulthood, specifically among children characterized by their first grade teacher as highly aggressive, disruptive. These results suggest that positive childhood peer relations may partially explain the GBG-associated reduction of risk for suicide attempts and may be an important and malleable protective factor for future suicide attempt.

Research has consistently shown that aggressive video console and PC games elicit aggressive cognitions, affect, and behaviors. Despite the increasing popularity of racing (driving) games, nothing is known about the psychological impact of this genre. This study investigated whether playing racing games affects cognitions, affect, and behaviors that can promote risk taking in actual road traffic situations. In Study 1, the authors found that the frequency of playing racing games was positively associated with competitive driving, obtrusive driving, and car accidents; a negative association with cautious driving was observed. To determine cause and effect, in Study 2, the authors manipulated whether participants played 1 of 3 racing games or 1 of 3 neutral games. Participants who played a racing game subsequently reported a higher accessibility of cognitions and affect positively associated with risk taking than did participants who played a neutral game. Finally, on a more behavioral level, in Study 3, the authors found that men who played a racing game subsequently took higher risks in computer-simulated critical road traffic situations than did men who played a neutral game. Theoretical and practical implications are discussed. ((c) 2007 APA, all rights reserved).

Several studies have reported laser printers as significant sources of nanosized particles ( -1 ; particle number 1.1-3.1 x 10 9 d -1 ) were estimated to correspond to 4-13 (mass) or 12-34 (number) deaths per million persons exposed on the basis of epidemiological risk estimates for ambient particles. These risks are higher than the generally used definition of acceptable risk of 1 x 10 -6 , but substantially lower than the estimated risks due to ambient particles. Toxicological studies on ambient particles revealed consistent values for lowest observed effect levels (LOELs) which were converted into equivalent daily uptakes using allometric scaling. These LOEL uptakes were by a factor of about 330-1,000 (mass) and 1,000-2,500 (particle surface area) higher than estimated uptakes from printers. This toxicological assessment would indicate no significant health risks due to printer particles. Finally, our study suggests that particle number (not mass) and mass (not surface area) are the most conservative risk metrics for the epidemiological and toxicological risks presented here, respectively.

Cultural differences between Black and White individuals in the South are connected to the inequitable history of the United States. We wondered if these cultural differences would translate to a particularly precious aspect of life: memories of love felt in childhood toward one's parents. Some past studies have shown that Whites score higher on parental attachment measures to parents than Blacks, while other studies show no significant differences. However, no previous study has ever measured memory of feelings of love in relation to differences between ethnicities. In this study, Black ( n = 124) and White ( n = 125) undergraduates self-reported the strength and frequency of their past feelings of love toward their mother and father in first, sixth, and ninth grade as well as their current feelings of love. Results suggested that Black students reported feeling more love for their mothers in first, sixth, and ninth grades compared to White students. These findings were not explained when we statistically adjusted for age, gender, socioeconomic status, education levels, income, number of years spent living with mother or father, stress, or personality. Therefore, this relationship may be explained by unmeasured or unmeasurable cultural differences. The direction of this effect was in the opposite direction from what we expected based on past attachment research. Given the inequities in U.S. history and the current discussions around ethnicity and race in the United States, the finding that Blacks reported higher remembered feelings of love for their mothers in childhood is intriguing and worthy of dissemination and discussion.

The present report represents the work product of the activities conducted by the Task Force. The TF performed a review and inventory of the existing approaches to risk-informed inservice inspection and testing, and completed its work in 1999 with a Current Practices Document 2, titled Report on risk-informed in-service inspection and in-service testing (EUR 19153 EN). In November 2001, the NRWG held a Special session on risk-informed applications, with emphasis on risk-informed inservice inspection, where results and experiences from pilot studies on risk-informed inservice inspection (RI-ISI), performed in several European countries, were presented and discussed. As a follow-up in May 2002, the TF was reconvened with the objectives to analyse from the regulatory point of view key aspects associated with the application of risk-informed inservice inspection, and to go beyond a state of the art report, presenting a series of recommendations of good practices or common positions reached by the regulators represented in the Task Force.

Visceral fat area (VFA), a novel sex-specific index for visceral fat obesity (VFO) might play a major role in the development of vitamin D deficiency. However, the association between VFA and vitamin D insufficiency and deficiency in Chinese population is less clear. The aim of this study was to explore the population-level association between VFA and vitamin D insufficiency and deficiency among Chinese men and women. This cross-sectional study involved 1105 adults aged 20-70 years living in Tianjin who were randomly selected and medically examined. All subjects underwent the bioelectrical impedance analysis (BIA) method to estimate the VFA. Serum 25-hydroxyvitamin D3 (25(OH) D3) level was assayed by the high-performance liquid chromatography (HPLC) method and defined insufficiency and deficiency following recommended cutoffs. The association between VFA and vitamin D insufficiency and deficiency was estimated using binary regression analysis. The total prevalence of vitamin D insufficiency (25(OH) D3: 20-29 μg/L) and deficiency (25(OH) D3 0.05). Moreover, increased VFA was observed to be associated with higher vitamin D insufficiency or deficiency risk with a positive dose-response trend (P for trend convenience surrogate marker for visceral adipose measurement and could be used in identifying the risk of vitamin D insufficiency and deficiency in routine health examination.

Almost daily, Americans receive reports from the mass news media about some new and frightening risk to health and welfare. Most such reports emphasize the newsworthiness of the risks -- the possibility of a crisis, disagreements among experts, how things happened, who is responsible for fixing them, how much will it cost, conflict among parties involved, etc. As a rule, the magnitudes of the risks, or the difficulty of estimating those magnitudes, have limited newsworthiness, and so they are not mentioned. Because of this emphasis in the news media, most people outside the risk assessment community must judge the relative significance of the various risks to which we all are exposed with only that information deemed newsworthy by reporters. This information is biased and shows risks in isolation. There is no basis for understanding and comparing the relative importance of risks among themselves, or for comparing one risk, perhaps a new or newly-discovered one, in the field of all risks. The purpose of this report is to provide perspective on the various risks to which we are routinely exposed. It serves as a basis for understanding the meaning of quantitative risk estimates and for comparing new or newly-discovered risks with other, better-understood risks. Specific emphasis is placed on health risks of energy technologies.

Full Text Available Abstract Background: There is controversy whether management of blood cholesterol should be based or not on LDL-cholesterol (LDL-c target concentrations. Objectives: To compare the estimated impact of different lipid-lowering strategies, based or not on LDL-c targets, on the risk of major cardiovascular events in a population with higher cardiovascular risk. Methods: We included consecutive individuals undergoing a routine health screening in a single center who had a 10-year risk for atherosclerotic cardiovascular disease (ASCVD ≥ 7.5% (pooled cohort equations, ACC/AHA, 2013. For each individual, we simulated two strategies based on LDL-c target (≤ 100 mg/dL [Starget-100] or ≤ 70 mg/dL [Starget-70] and two strategies based on percent LDL-c reduction (30% [S30%] or 50% [S50%]. Results: In 1,897 subjects (57 ± 7 years, 96% men, 10-year ASCVD risk 13.7 ± 7.1%, LDL-c would be lowered from 141 ± 33 mg/dL to 99 ± 23 mg/dL in S30%, 71 ± 16 mg/dL in S50%, 98 ± 9 mg/dL in Starget-100, and 70 ± 2 mg/dL in Starget-70. Ten-year ASCVD risk would be reduced to 8.8 ± 4.8% in S50% and 8.9 ± 5.2 in Starget-70. The number of major cardiovascular events prevented in 10 years per 1,000 individuals would be 32 in S30%, 31 in Starget-100, 49 in S50%, and 48 in Starget-70. Compared with Starget-70, S50% would prevent more events in the lower LDL-c tertile and fewer events in the higher LDL-c tertile. Conclusions: The more aggressive lipid-lowering approaches simulated in this study, based on LDL-c target or percent reduction, may potentially prevent approximately 50% more hard cardiovascular events in the population compared with the less intensive treatments. Baseline LDL-c determines which strategy (based or not on LDL-c target is more appropriate at the individual level.

Hospital report cards, in which outcomes following the provision of medical or surgical care are compared across health care providers, are being published with increasing frequency. Essential to the production of these reports is risk-adjustment, which allows investigators to account for differences in the distribution of patient illness severity across different hospitals. Logistic regression models are frequently used for risk adjustment in hospital report cards. Many applied researchers use the c-statistic (equivalent to the area under the receiver operating characteristic curve) of the logistic regression model as a measure of the credibility and accuracy of hospital report cards. To determine the relationship between the c-statistic of a risk-adjustment model and the accuracy of hospital report cards. Monte Carlo simulations were used to examine this issue. We examined the influence of 3 factors on the accuracy of hospital report cards: the c-statistic of the logistic regression model used for risk adjustment, the number of hospitals, and the number of patients treated at each hospital. The parameters used to generate the simulated datasets came from analyses of patients hospitalized with a diagnosis of acute myocardial infarction in Ontario, Canada. The c-statistic of the risk-adjustment model had, at most, a very modest impact on the accuracy of hospital report cards, whereas the number of patients treated at each hospital had a much greater impact. The c-statistic of a risk-adjustment model should not be used to assess the accuracy of a hospital report card.

Dispositional optimism and risk perceptions are each associated with health-related behaviors and decisions and other outcomes, but little research has examined how these constructs interact, particularly in consequential health contexts. The predictive validity of risk perceptions for health-related information seeking and intentions may be improved by examining dispositional optimism as a moderator, and by testing alternate types of risk perceptions, such as comparative and experiential risk. Participants (n = 496) had their genomes sequenced as part of a National Institutes of Health pilot cohort study (ClinSeq®). Participants completed a cross-sectional baseline survey of various types of risk perceptions and intentions to learn genome sequencing results for differing disease risks (e.g., medically actionable, nonmedically actionable, carrier status) and to use this information to change their lifestyle/health behaviors. Risk perceptions (absolute, comparative, and experiential) were largely unassociated with intentions to learn sequencing results. Dispositional optimism and comparative risk perceptions interacted, however, such that individuals higher in optimism reported greater intentions to learn all 3 types of sequencing results when comparative risk was perceived to be higher than when it was perceived to be lower. This interaction was inconsistent for experiential risk and absent for absolute risk. Independent of perceived risk, participants high in dispositional optimism reported greater interest in learning risks for nonmedically actionable disease and carrier status, and greater intentions to use genome information to change their lifestyle/health behaviors. The relationship between risk perceptions and intentions may depend on how risk perceptions are assessed and on degree of optimism. (c) 2015 APA, all rights reserved.
Incidence Patterns and Occupational Risk Factors of Human Brucellosis in Greece, 2004-2015.
Lytras, T; Danis, K; Dounias, G
2016-10-01
Brucellosis is the most common bacterial zoonosis worldwide. Greece has the highest reported incidence among EU countries. However, occupational risk factors have not been well described. To determine the incidence patterns and exposure risk factors of brucellosis in Greece. We used national-level surveillance and occupational denominator data to estimate the incidence patterns and exposure risk factors of brucellosis in Greece, with particular emphasis on occupation. Between November 2003 and December 2015 a total of 2159 human brucellosis cases was reported. The mean incidence rate was 1.62 per 100 000 population per year. A large majority of cases (77.1%) reported consumption of unpasteurized milk or contact with livestock animals. Most cases occured in farmers and livestock breeders (1079 [87.7%] of 1231 cases reporting their occupation), corresponding to an annual incidence of 7.1 per 100 000. However, there were other occupations with a similar or higher risk: butchers and abattoir workers (12.7 per 100 000), laboratory personnel (3.1 per 100 000), while the highest risk was for veterinarians (53.2 per 100 000). Brucellosis incidence in specific occupational groups was much higher than in the general population. These results underline the importance of collecting information on occupation, both during the diagnostic process and in the surveillance system. Besides efforts to control brucellosis in animals, organized prevention efforts are needed within an occupational health framework, especially for the most vulnerable workers.

Cardiovascular disease (CVD) is responsible for more than half of all deaths in the European region. The aim of the study was to compare body composition, blood pressure, total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C), family history, activity behaviors, and the 10-year risk of having a heart attack between 166 university students (21.62 ± 2.59 yrs) from Utah (USA) and 198 students (22.11 ± 2.51 yrs) from Hungary. Ninety-two percent of the Hungarian students and 100% of the Utah students had an estimated 10-year Framingham risk score of 1% or less. The high prevalence of low risk was primarily due to the young age of study participants, healthy body composition and non-smoking behavior. Hungarians who had higher 10-year risk of heart attack had significantly higher waist hip ratio (WHR), TC, diastolic blood pressure (DBP) and were smokers compared to those Hungarians with lower risk. The self-reported physical activity levels between the two groups of students were not different. In conclusion the young men and women who participated in this study were, for the most part healthy; however the smoking habits and the lower physical activity of the Hungarian students likely elevated their risk of CVD.

Associations between park use and infections with gastrointestinal (GI) parasites in dogs (Canis familiaris) have been previously observed, suggesting park use may pose risks for infection in dogs, and potentially, in humans. This study was conducted to establish the overall level of perceived risk of parasitism in dogs, the frequency of unleashing dogs in parks, and to determine if dog owners' risk perceptions of parasite transmission among humans and dogs are associated with the reported frequency of unleashing dogs. From June to September 2010, 635 surveys were administered to dog owners in nine city parks in Calgary, Alberta, by the lead author to explore dog-walking behaviors in parks under differing leashing regulations. From these, a subset of 316 questionnaires were analyzed to examine associations between behavioral and dog demographic factors, risk perception and acceptability of perceived risks of dog and human parasitism, and education regarding parasitism in dogs and humans. Multivariate statistics were conducted using three separate Chi-Square Automatic Interaction Detection (CHAID) decision trees to model risk perception of dogs becoming parasitized while in the park, risk perception of zoonotic transmission, and off-leash frequency. Predictors included recreational behaviors, dog demographics, risk perception of park-based and zoonotic transmission, education regarding parasites, and leashing regulations (e.g. on-leash, off-leash, or mixed management parks). The perceived risk of park-based transmission was relatively higher than perception of zoonotic transmission and the majority of people unleashed their dogs at least some of the time. Risk perception was not associated with off-leash frequency in dogs and risk perception and off-leash frequency were associated with factors other than each other. The results suggest owners may underestimate the potential risks for parasitism related to some dog-walking behaviours, and are relevant for public and

This pilot study is based on the assumption and the knowledge that previous results show that the normal use of the word risk varies across subjects. The risk definitions the subjects use have also been shown to be related to various educational interests. A related field of research has developed measures for Sensation Seeking personality trait, with four facets. Three independent groups of first year psychology students reported their normal definition of the word risk using one of three measurement formats. The results showed, e.g. that the typical open-ended response to the personal definition of risk was danger. Subjects who defined risk as the combination of probability and consequences tended to score higher on the total Sensation Seeking Scale, as compared to those defining risk as the probability of an event

Psychiatrists are mandated to report suspicions of child abuse in America. Potential for harm to children should be considered when one is treating parents who are at risk. Although it is the commonly held wisdom that mental illness itself is a major risk factor for child abuse, there are methodologic issues with studies purporting to demonstrate this. Rather, the risk from an individual parent must be considered. Substance abuse and personality disorder pose a separate risk than serious mental illness. Violence risk from mental illness is dynamic, rather than static. When severe mental illness is well-treated, the risk is decreased. However, these families are in need of social support.

Concussions may accelerate the progression to long-term mental health outcomes such as depression in athletes. To prospectively determine the effects of recurrent concussions on the clinical diagnosis of depression in a group of retired football players. Cohort study; Level of evidence, 2. Members of the National Football League Retired Players Association responded to a baseline General Health Survey (GHS) in 2001. They also completed a follow-up survey in 2010. Both surveys asked about demographic information, number of concussions sustained during their professional football career, physical/mental health, and prevalence of diagnosed medical conditions. A physical component summary (Short Form 36 Measurement Model for Functional Assessment of Health and Well-Being [SF-36 PCS]) was calculated from responses for physical health. The main exposure, the history of concussions during the professional playing career (self-report recalled in 2010), was stratified into 5 categories: 0 (referent), 1 to 2, 3 to 4, 5 to 9, and 10+ concussions. The main outcome was a clinical diagnosis of depression between the baseline and follow-up GHS. Classic tabular methods computed crude risk ratios. Binomial regression with a Poisson residual and robust variance estimation to stabilize the fitting algorithm estimated adjusted risk ratios. χ(2) analyses identified associations and trends between concussion history and the 9-year risk of a depression diagnosis. Of the 1044 respondents with complete data from the baseline and follow-up GHS, 106 (10.2%) reported being clinically diagnosed as depressed between the baseline and follow-up GHS. Approximately 65% of all respondents self-reported sustaining at least 1 concussion during their professional careers. The 9-year risk of a depression diagnosis increased with an increasing number of self-reported concussions, ranging from 3.0% in the "no concussions" group to 26.8% in the "10+" group (linear trend: P football and 2001 SF-36 PCS

Cardiovascular disease (CVD) caused significant burden to Malaysia as it accounted for 36% of total deaths. This study aims to evaluate the burden of cardiovascular risk factors among Malaysian adult and assess the difference between urban and rural population in the selected communities. This study is part of the ongoing Prospective Urban Rural Epidemiology (PURE) database, whereby the baseline data were collected since June 2008. CVD risk was measured using INTERHEART risk score which comprised of eleven risk factors i.e. age and gender, family history of heart attack, smoking status, exposure to second hand smoke, diabetes mellitus, hypertension status, waist-hip ratio, self-reported stress, depression, dietary habits and physical activity status. Majority of the studied participants had low cardiovascular risk (57%). Participants from rural area were generally older, had lower educational status, higher prevalence of smokers, obesity, hypertension, diabetes, and more likely to be depressed. In comparison, urbanites had lower physical activities and more likely to be stressful. Mean INTERHEART score among rural participants were higher, especially for male, in comparison to urbanite (11.5±5.83 vs. 10.01±5.74, p<0.001). Contradict to common beliefs, participants in rural areas generally have higher cardiovascular risk factors compared to their urban counterparts. The rural population should be targeted for focused preventive interventions, taking account the socioeconomic and cultural context.
Hazard risk and vulnerability assessment : Regional District of Nanaimo : final report

2006-06-01
A Hazard Risk and Vulnerability Assessment (HRVA) is a mandated regulatory requirement in British Columbia that requires local authorities to prepare emergency plans that reflect the local authority's assessment of the relative risk of occurrence and the potential impact on people and property of the hazards, emergencies or disasters that could affect the jurisdictional area for which the local authority has responsibility. This report constituted an HRVA for the Regional District of Nanaimo, British Columbia. It presented the study scope and methodology and provided an overview of the Regional District of Nanaimo. This included information on the setting, demographics, and economy. Next, it discussed social vulnerability; critical response and recovery facilities; and critical infrastructure such as water, energy, telecommunications and transportation. A summary of the Regional District of Nanaimo's response capabilities that were considered when assessing the Regional District's overall risk to the hazards was also presented. Response capabilities were discussed with reference to fire and rescue; police; ambulance; and search and rescue. Emergency support and preparedness organizations were also identified. These included the Emergency Coordination Centre, environmental services, emergency social services, amateur radio and health authorities. Last, 33 hazards that could affect the Regional District of Nanaimo were identified and discussed. The study identified the following hazards as high risk: flooding; forest fires and wildland urban interface fires; and human diseases and pandemic. It was recommended that the advancement of business continuity planning in the Regional District of Nanaimo would help to reduce the impact of a possible human disease and pandemic risk outbreak affecting the population. 75 refs., 25 figs., 14 tabs., 2 appendices
Sun protection and sunbathing practices among at-risk family members of patients with melanoma
2011-01-01
Background Despite the increased level of familial risk, research indicates that family members of patients with melanoma engage in relatively low levels of sun protection and high levels of sun exposure. The goal of this study was to evaluate a broad range of demographic, medical, psychological, knowledge, and social influence correlates of sun protection and sunbathing practices among first-degree relatives (FDRs) of melanoma patients and to determine if correlates of sun protection and sunbathing were unique. Methods We evaluated correlates of sun protection and sunbathing among FDRs of melanoma patients who were at increased disease risk due to low compliance with sun protection and skin surveillance behaviors. Participants (N = 545) completed a phone survey. Results FDRs who reported higher sun protection had a higher education level, lower benefits of sunbathing, greater sunscreen self-efficacy, greater concerns about photo-aging and greater sun protection norms. FDRs who reported higher sunbathing were younger, more likely to be female, endorsed fewer sunscreen barriers, perceived more benefits of sunbathing, had lower image norms for tanness, and endorsed higher sunbathing norms. Conclusion Interventions for family members at risk for melanoma might benefit from improving sun protection self-efficacy, reducing perceived sunbathing benefits, and targeting normative influences to sunbathe.

Incisal tooth wear may be a sign of long-term bruxing behavior. Bruxism is purported to be a risk factor for temporomandibular disorders (TMD). The aim of this population-based cross-sectional study was to determine if anterior tooth wear is associated with the self-report of TMD pain in children and adolescents. In a population sample of 1,011 children and adolescents (mean age 13.1 years, range 10 to 18 years; female 52%; response rate 85%), TMD cases were defined as subjects reporting pain in the face, jaw muscles, and temporomandibular joint during the last month according to RDC/TMD. All other subjects were considered controls. Incisal tooth wear was assessed in the clinical examination using a 0 to 2 scale (no wear, enamel wear, dentin wear) for every anterior permanent tooth. The mean wear score for the individuals was categorized into 0, 0.01 to 0.20, 0.21 to 0.40, and 0.41+. A multiple logistic regression analysis, controlling for the effects of age and gender, analyzed the association between the categorized summary wear score and TMD. Specifically, the hypothesis of a trend between higher tooth wear scores and higher risk of TMD was tested. An odds ratio of 1.1 indicated, after adjusting for gender and age, no statistically significantly higher risk of TMD pain with higher tooth wear scores. Incisal tooth wear was not associated with self-reported TMD pain in 10- to 18-year-old subjects.

Considerable research has examined reciprocal relationships between parenting, peers and adolescent problem behavior; however, such studies have largely considered the influence of peers and parents separately. It is important to examine simultaneously the relationships between parental monitoring, peer risk involvement and adolescent sexual risk behavior, and whether increases in peer risk involvement and changes in parental monitoring longitudinally predict adolescent sexual risk behavior. Four waves of sexual behavior data were collected between 2008/2009 and 2011 from high school students aged 13-17 in the Bahamas. Structural equation and latent growth curve modeling were used to examine reciprocal relationships between parental monitoring, perceived peer risk involvement and adolescent sexual risk behavior. For both male and female youth, greater perceived peer risk involvement predicted higher sexual risk behavior index scores, and greater parental monitoring predicted lower scores. Reciprocal relationships were found between parental monitoring and sexual risk behavior for males and between perceived peer risk involvement and sexual risk behavior for females. For males, greater sexual risk behavior predicted lower parental monitoring; for females, greater sexual risk behavior predicted higher perceived peer risk involvement. According to latent growth curve models, a higher initial level of parental monitoring predicted decreases in sexual risk behavior, whereas both a higher initial level and a higher growth rate of peer risk involvement predicted increases in sexual risk behavior. Results highlight the important influence of peer risk involvement on youths' sexual behavior and gender differences in reciprocal relationships between parental monitoring, peer influence and adolescent sexual risk behavior.

The Chemical Technology Division of the Oak Ridge National Laboratory has prepared a set of documents that evaluate a Partitioning-Transmutation (PT) fuel cycle relative to a Reference cycle employing conventional fuel-material recovery methods. The PT cycle uses enhanced recovery methods so that most of the long-lived actinides are recycled to nuclear power plants and transmuted to shorter-lived materials, thereby reducing the waste toxicity. This report compares the two fuel cycles on the basis of the short-term radiological and nonradiological risks they present to the public and to workers. The accidental radiological risk to the public is analyzed by estimating the probabilities of sets of accidents; the consequences are calculated using the CRAC code appropriately modified for the material composition. Routine radiological risks to the public are estimated from the calculated release amounts; the effects are calculated using the CRAC code. Radiological occupational risks are determined from prior experience, projected standards, and estimates of accident risk. Nonradiological risks are calculated from the number of personnel involved, historical experience, and epidemiological studies. The result of this analysis is that the short-term risk of PT is 2.9 times greater than that of the Reference cycle, primarily due to the larger amount of industry. This conclusion is strongly dominated by the nonradiological risk, which is about 150 times greater than the radiological risk. The absolute risk as estimated for the fuel cycle portions considered in this report is 0.91 fatalities/GWe-year for the PT cycle and 0.34 fatalities/GWe-year for the Reference cycle. This should be compared with Inhaber's estimate of 1.5 for nuclear and 150 for coal. All of the risks assumed here are associated with the production of one billion watts of electricity (GWe) per year

We assessed the effects of beliefs about state HIV criminal law on condomless anal sex (CAS law(s) or where a HIV-related arrest, prosecution, or sentence enhancement (APSE) had occurred. Three-quarters of MSM reported that they were unsure of the law in their state. Men who believed there was a HIV law in their state but lived in states without any or a sex-specific HIV criminal law(s) had higher probabilities of CAS compared to those who were unsure of their state's law; men who believed there was a HIV law in their state and lived in a state where an APSE had occurred had higher probabilities of CAS compared to those who were unsure of their state's law. Correct knowledge of state law was not associated with CAS. Findings suggest that HIV criminal laws have little or counter-productive effects on MSM's risk behavior.

Young people with MSPs are less likely to use a condom and the greater the risk for STIs. This study examines the associated risk factors of STIs and multiple sexual partnerships among youths aged 15-24 years.The Malawi Demographic Health Survey 2010 data was used. Out of a sample of 2,987 males and 9,559 females aged 15-24 years, 2,026 males and 6,470 females were considered in the study. Chi square test and logistic regression techniques were performed. Analysis was performed using Statistical Package for Social Sciences (SPSS version 22.The results indicate that 1,399 (69.0% males and 2,290 (35.4% females reported multiple sexual partnerships (MSP. Within the rural area, females (n = 1779 were more likely to report MSP than males (n = 1082 and within the urban areas, a higher proportion of females (n = 511 still reported MSP, with males (n = 316. About 78% rural females aged 20-24 years, and about 79% rural males aged 15-19 years reported MSP. The likelihood of MSP was higher among females in the poorest households (OR = 1.31, being married (OR = 5.71 and Catholic males (OR = 1.63, who were married (OR = 1.59. Catholic males (OR = 1.82 in the rural areas, who were married (OR = 1.80 and rural females in the northern region (OR = 1.26 were more likely to have MSP. The odds ratios were higher among urban females in the poorest (OR = 3.45 households who were married (OR = 4.22.Having more than one sexual partner increases the risk of STIs and sexuality education programs should be introduced that emphasize the danger that surrounds MSP.

Full Text Available Globally, in every facet of life, advances in communications technology and our reliance on computers and the internet allow us to live and work more efficiently than ever before. Higher education relies on the development of knowledge and the need to conduct and communicate research activity. Universities are often bound in research activity to business, government and other organizations whose interests need to be protected and managed. But is there a disparity in approach? Is research activity, security and the protection of privileged, proprietary and classified information appropriately implemented and managed in higher education? In this article the author questions: are there gaps open to cyberattack?

Risk of the Metabolic Syndrome in Sexual Minority Women: Results from the ESTHER Study.
Kinsky, Suzanne; Stall, Ron; Hawk, Mary; Markovic, Nina
2016-08-01
Compared to heterosexuals, sexual minority women (SMW) have higher rates of the metabolic syndrome risk factors (e.g., obesity, smoking, heavy drinking, and depression). Yet, no published research has examined whether SMW have higher rates of the metabolic syndrome. The aim of this study is to describe the prevalence of the metabolic syndrome and its individual factors in a sample of heterosexuals and SMW, and identify whether SMW are at greater risk of having the metabolic syndrome. Data are from the Epidemiologic STudy of HEalth Risk in Women (ESTHER), a cross-sectional convenience sample of 479 SMW and 400 heterosexual women from Pittsburgh, Pennsylvania. Participants provided self-report questionnaire data, clinical data, and blood work. Compared to heterosexuals, SMW had higher mean waist circumference, fasting glucose, and systolic and diastolic blood pressure. Nearly one-quarter (24.3%) of SMW had the metabolic syndrome compared to 15.6% of heterosexual women (p = 0.002). After controlling for demographic and risk factors, SMW had a 44% higher risk of having the metabolic syndrome than heterosexuals (p = 0.031). To our knowledge, this is the first study to identify this health disparity in SMW. Future studies should explore differential risk of mortality and metabolic health between SMW and heterosexuals.

Treatment with azacitidine (AZA) has been suggested to be of benefit for higher-risk myelodysplastic syndrome (HR-MDS) patients with chromosome 7 abnormalities (Abn 7). This retrospective study of 235 HR-MDS patients with Abn 7 treated with AZA (n = 115) versus best supportive care (BSC; n = 120), assessed AZA treatment as a time-varying variable in multivariable analysis. A Cox Regression model with time-interaction terms of overall survival (OS) at different time points confirmed that, while chromosome 7 cytogenetic categories (complex karyotype [CK] versus non-CK) and International Prognostic Scoring System risk (high versus intermediate-2) retained poor prognosis over time, AZA treatment had a favourable impact on OS during the first 3 years of treatment compared to BSC (Hazard ratio [HR] 0·5 P MDS and cytogenetic abnormalities involving chromosome 7, especially for those with CK. © 2018 John Wiley & Sons Ltd.

Suicide risk is high among people living with HIV (PLHIV). This study aimed to identify major correlates of suicide risk in a representative sample of PLHIV in France, in order to help target individuals who would benefit from suicide risk screening and psychiatric care. The ANRS VESPA2 cross-sectional survey (April 2011-January 2012) collected socio-demographic, medical and behavioral data from 3,022 PLHIV recruited in 73 French HIV hospital departments. The study sample comprised the 2,973 participants with available self-reported data on suicide risk (defined as having either thought about and planned to commit suicide during the previous 12 months or attempted suicide during the same period of time) and medical data on comorbidities. Weighted Poisson models adjusted for HCV co-infection and significant clinical variables were used to estimate the relationship between suicide risk and HIV transmission groups, experience with HIV disease and other psychosocial factors. Suicide risk was reported by 6.3% of PLHIV in the study sample. After adjustment for HIV immunological status and HCV co-infection, women (IRR [95%CI]:1.93 [1.17; 3.19]) and men who have sex with men (MSM) (1.97 [1.22; 3.19]) had a higher suicide risk than the rest of the sample. Moreover, the number of discrimination-related social contexts reported (1.39 [1.19; 1.61]), homelessness (4.87 [1.82; 13.02]), and reporting a feeling of loneliness (4.62 [3.06; 6.97]) were major predictors of suicide risk. Reducing the burden of precarious social conditions and discrimination is an important lever for preventing suicide risk among PLHIV in France. Comprehensive care models involving peer/community social interventions targeted at women and MSM need to be implemented to lower the risk of suicide in these specific subgroups of PLHIV.

The present report continues the series of general reports on mortality in the Life Span Study (LSS) cohort followed by the Radiation Effects Research Foundation (RERF). The present report deals with solid cancer and non-cancer disease mortality during the period from 1950 through 1997, updating with seven additional years of follow-up LSS Report 12. The LSS cohort includes 86,572 people with individual dose estimates. There have been 9,335 deaths from solid cancer and 31,881 deaths from non-cancer disease during the 47 years follow-up. 19% of the solid cancer and 15% of the non-cancer disease deaths occurred during the newly added follow-up period. While excess rates for radiation-associated solid cancers are seen to increase throughout the study period regardless of age at exposure, relative risks are highest for those exposed as children but appear to decline with increasing age. For those exposed at age 30 the solid cancer risk is elevated by 47% at age 70. There are interesting variations by site of age and age at exposure pattern, though the patterns of the risk do not differ statistically from those for solid cancer as a group. However, the interpretation of age at exposure effects on the ERR or the EAR is complicated by changes in background rates with birth cohort or time trend. The evidence for radiation effects on non-cancer mortality remains strong with risks increased by about 14% per Sv during the last thirty years of follow-up. Statistically significant increases are seen for heart disease, stroke, digestive diseases, and respiratory diseases. Although the non-cancer data are consistent with some non-linearity in the dose response, the evidence against linearity is weaker than past. However, there is no direct statistical evidence of radiation effects for doses less than 0.5 Sv

Compared with the general population, people with a mental illness have a greater prevalence of behaviors that contribute to higher chronic disease rates. Mental health clinical guidelines recommend preventive care to address such behaviors; however, little information is available about whether clients consider preventive care acceptable or about the prevalence of such care in mental health services. This article describes acceptability and receipt of assessment, advice, and referral for smoking, inadequate fruit and vegetable consumption, harmful alcohol consumption, and physical inactivity, as reported by community mental health service clients. The association between preventive care, diagnosis, and number of clinical appointments was examined. A cross-sectional telephone interview was conducted with clients (N=558) of community mental health services in Australia. Although preventive care was highly acceptable to clients (86%-97%), receipt of preventive care was low. Client receipt of risk assessment ranged from 26% (assessment of fruit or vegetable intake) to 76% (assessment of alcohol consumption). The proportion of clients at risk of and assessed for unhealthy behavior who then received brief advice ranged from 69% (fruit or vegetable intake) to 85% (physical activity), whereas only 38% (alcohol consumption) to 49% (smoking) received any referral. A greater number of mental health appointments were associated with higher prevalence of preventive care, as were diagnoses of diabetes or respiratory conditions and not having a schizophrenia diagnosis. Practice change strategies are required to increase the delivery of routine preventive care within mental health services if clients are to benefit from clinical guidelines.

Full Text Available Background: Brucellosis is the most common bacterial zoonosis worldwide. Greece has the highest reported incidence among EU countries. However, occupational risk factors have not been well described. Objective: To determine the incidence patterns and exposure risk factors of brucellosis in Greece. Methods: We used national-level surveillance and occupational denominator data to estimate the incidence patterns and exposure risk factors of brucellosis in Greece, with particular emphasis on occupation. Results: Between November 2003 and December 2015 a total of 2159 human brucellosis cases was reported. The mean incidence rate was 1.62 per 100 000 population per year. A large majority of cases (77.1% reported consumption of unpasteurized milk or contact with livestock animals. Most cases occured in farmers and livestock breeders (1079 [87.7%] of 1231 cases reporting their occupation, corresponding to an annual incidence of 7.1 per 100 000. However, there were other occupations with a similar or higher risk: butchers and abattoir workers (12.7 per 100 000, laboratory personnel (3.1 per 100 000, while the highest risk was for veterinarians (53.2 per 100 000. Conclusion: Brucellosis incidence in specific occupational groups was much higher than in the general population. These results underline the importance of collecting information on occupation, both during the diagnostic process and in the surveillance system. Besides efforts to control brucellosis in animals, organized prevention efforts are needed within an occupational health framework, especially for the most vulnerable workers.

We examined normative beliefs about multiple sexual partners and social status in China and their association with risky sexual behaviors and sexually transmitted infections (STIs). Self-reported and biological markers of sexual risk were examined among 3,716 market vendors from a city in eastern China. Men who were older or with less education believed having multiple sexual partners was linked to higher social status. Adjusting for demographic characteristics, normative beliefs were significantly associated with having multiple sexual partners, while having multiple sexual partners was significantly associated with STIs. Normative beliefs regarding sexual behaviors may play an important role in individual risk behaviors. Future HIV/STI interventions must address community beliefs about the positive meaning of sexual risks, particularly among men with traditional beliefs about gender roles.

Familial Multiple Myeloma: Report on Two Families and Discussion of Screening Options

2007-06-01
Full Text Available Abstract Multiple myeloma (MM is a relatively rare haematological malignancy seen in older persons. It has an unknown aetiology and usually occurs incidentally within a family. However, several families have been reported with multiple cases of MM, so that the existence of hereditary MM has been postulated although no causative germline mutations have been detected so far. First-degree relatives of MM patients have been reported to have a relative risk between two and four times higher than normal of developing MM and we presume the risks are higher for relatives in the case of familial MM. Here we report on two families with MM who requested presymptomatic screening of healthy relatives. Although risk estimates for asymptomatic relatives in these types of families are not available, a clinically significant risk of developing MM cannot be excluded. We suggest that, in a research setting, screening for MM could be offered to individuals with more than one first-degree affected relative, or to those with one first-degree and at least one second-degree relative with MM. We propose a screening programme of annual protein electrophoresis of blood and urine, starting at age 40 (or earlier if a family member presented with MM at a younger age.

The rising potential for the release of engineered nanoparticles (ENPs) into aquatic environments requires evaluation of risks to protect ecological health. The present review examines knowledge pertaining to the interactions of metal-based ENPs with aquatic higher plants, identifies information gaps, and raises considerations for future research to advance knowledge on the subject. The discussion focuses on ENPs' bioaccessibility; uptake, adsorption, translocation, and bioaccumulation; and toxicity effects on aquatic higher plants. An information deficit surrounds the uptake of ENPs and associated dynamics, because the influence of ENP characteristics and water quality conditions has not been well documented. Dissolution appears to be a key mechanism driving bioaccumulation of ENPs, whereas nanoparticulates often adsorb to plant surfaces with minimal internalization. However, few reports document the internalization of ENPs by plants; thus, the role of nanoparticulates' internalization in bioaccumulation and toxicity remains unclear, requiring further investigation. The toxicities of metal-based ENPs mainly have been associated with dissolution as a predominant mechanism, although nano toxicity has also been reported. To advance knowledge in this domain, future investigations need to integrate the influence of ENP characteristics and water physicochemical parameters, as their interplay determines ENP bioaccessibility and influences their risk to health of aquatic higher plants. Furthermore, harmonization of test protocols is recommended for fast tracking the generation of comparable data. Environ Toxicol Chem 2016;35:1677-1694. © 2016 SETAC. © 2016 SETAC.

Risk analysis is increasingly promoted as a tool to support science-based decisions regarding food safety. An online survey comprising 45 questions was used to gather information on the implementation of food safety risk analysis within the Latin American and Caribbean regions. Professionals working in food safety in academia, government, and private sectors in Latin American and Caribbean countries were contacted by email and surveyed to assess their individual knowledge of risk analysis and perceptions of its implementation in the region. From a total of 279 participants, 97% reported a familiarity with risk analysis concepts; however, fewer than 25% were able to correctly identify its key principles. The reported implementation of risk analysis among the different professional sectors was relatively low (46%). Participants from industries in countries with a long history of trade with the United States and the European Union, such as Mexico, Brazil, and Chile, reported perceptions of a higher degree of risk analysis implementation (56, 50, and 20%, respectively) than those from the rest of the countries, suggesting that commerce may be a driver for achieving higher food safety standards. Disagreement among respondents on the extent of the use of risk analysis in national food safety regulations was common, illustrating a systematic lack of understanding of the current regulatory status of the country. The results of this survey can be used to target further risk analysis training on selected sectors and countries.

Excessive fluid therapy in patients with sepsis may be associated with risks that outweigh any benefit. We investigated the possible influence of early fluid balance on outcome in a large international database of ICU patients with sepsis. Observational cohort study. Seven hundred and thirty ICUs in 84 countries. All adult patients admitted between May 8 and May 18, 2012, except admissions for routine postoperative surveillance. For this analysis, we included only the 1,808 patients with an admission diagnosis of sepsis. Patients were stratified according to quartiles of cumulative fluid balance 24 hours and 3 days after ICU admission. ICU and hospital mortality rates were 27.6% and 37.3%, respectively. The cumulative fluid balance increased from 1,217 mL (-90 to 2,783 mL) in the first 24 hours after ICU admission to 1,794 mL (-951 to 5,108 mL) on day 3 and decreased thereafter. The cumulative fluid intake was similar in survivors and nonsurvivors, but fluid balance was less positive in survivors because of higher fluid output in these patients. Fluid balances became negative after the third ICU day in survivors but remained positive in nonsurvivors. After adjustment for possible confounders in multivariable analysis, the 24-hour cumulative fluid balance was not associated with an increased hazard of 28-day in-hospital death. However, there was a stepwise increase in the hazard of death with higher quartiles of 3-day cumulative fluid balance in the whole population and after stratification according to the presence of septic shock. In this large cohort of patients with sepsis, higher cumulative fluid balance at day 3 but not in the first 24 hours after ICU admission was independently associated with an increase in the hazard of death.

Personality traits such as conscientiousness as self-reported by individuals can help predict a range of outcomes, from job performance to longevity. Asking others to rate the personality of their acquaintances often provides even better predictive power than using self-report. Here, we examine whether peer-reported personality can provide a better link between brain function, namely threat-related amygdala activity, and future health-related behavior, namely problem drinking, than self-reported personality. Using data from a sample of 377 young adult university students who were rated on five personality traits by peers, we find that higher threat-related amygdala activity to fearful facial expressions is associated with higher peer-reported, but not self-reported, conscientiousness. Moreover, higher peer-reported, but not self-reported, conscientiousness predicts lower future problem drinking more than one year later, an effect specific to men. Remarkably, relatively higher amygdala activity has an indirect effect on future drinking behavior in men, linked by peer-reported conscientiousness to lower future problem drinking. Our results provide initial evidence that the perceived conscientiousness of an individual by their peers uniquely reflects variability in a core neural mechanism supporting threat responsiveness. These novel patterns further suggest that incorporating peer-reported measures of personality into individual differences research can reveal novel predictive pathways of risk and protection for problem behaviors.

The aim of this study was to assess the risk of port system failure in patients with advanced cancer. We conducted a retrospective cohort study in a comprehensive cancer centre. A detailed chart review was conducted among 566 patients with 573 ports inserted during January-June, 2009 (average 345.3 catheter-days). Cox regression analysis was applied to evaluate factors during insertion and early maintenance that could lead to premature removal of the port systems due to infection or occlusion. Port system-related infection was significantly associated with receiving palliative care immediately after implantation (hazard ratio, HR = 7.3, 95% confidence interval, 95% CI = 1.2-46.0), after adjusting for probable confounders. Primary cancer site also impacted the occurrence of device-related infection. Receiving oncologic/palliative care (HR = 3.0, P = 0.064), advanced cancer stage (HR = 6.5, P = 0.077) and body surface area above 1.71 m(2) (HR = 3.4, P = 0.029) increased the risk of port system occlusion. Our study indicates that totally implantable port systems yield a higher risk of complications in terminally ill patients. Further investigation should be carefully conducted to compare outcomes of various central venous access devices in patients with advanced cancer and to develop preventive strategies against catheter failure.

Previous studies have suggested an immunological dysfunction in mood disorders, but rarely have investigated the temporal association between allergic diseases and mood disorders. Using the Taiwan National Health Insurance Research Database, we attempted to investigate the association between asthma in early adolescence and the risk of unipolar depression and bipolar disorder in later life. In all, 1453 adolescents with asthma aged between 10 and 15 years and 5812 age-/gender-matched controls were selected in 1998-2000. Subjects with unipolar depression and bipolar disorder that occurred up to the end of follow-up (December 31 2010) were identified. Adolescents with asthma had a higher incidence of major depression (2.8% vs. 1.1%, p bipolar disorder (1.0% vs. 0.3%, p adolescence was associated with an increased risk of developing major depression (hazard ratio [HR]: 1.81, 95% confidence interval [CI]: 1.14-2.89), any depressive disorder (HR: 1.74, 95% CI: 1.27-2.37), and bipolar disorder (HR: 2.27, 95% CI: 1.01-5.07), after adjusting for demographic data and comorbid allergic diseases. Adolescents with asthma had an elevated risk of developing mood disorders in later life. Further studies would be required to investigate the underlying mechanisms for this comorbid association and elucidate whether prompt intervention for asthma would decrease the risk of developing mood disorders.
