In the experiments with mice of Af line, irradiated by gamma-radiation with doses of up to 1.0 Gy and subjected to psycho-emotional effect (the model of 'the provoked aggression') have been investigated the processes of tumour formation. The index of cariogenic efficiency of effects is the number of the induced adenomas in lungs. It has been shown that under separate effect of these factors the frequency of adenomas increases. Under the combined effect the additional number of adenomas per mouse is registered, which exceeds theoretically the expected value assuming additivity of effects, the synergism coefficient was 1.57 (for females). It has been marked that the character of tumour reaction on separate and the combined effect of radiation, as well as the stress-factor has sex distinctions. It has been shown that that real assessment of the radiation risk and the development of the measures system on minimization of medical and biological consequences of the accident should take into account not only the radiation factor, but also a psychological one, especially in those cases when realization of the risk of combined effect of radiation and non-radiation factors can manifest synergism

Full Text Available Purpose of the review:Pancreatic cancer is extremely aggressive, forming highly chemo-resistant tumors, and has one of the worst prognoses. The evolution of this cancer is multi-factorial. Repeated acute pancreatic injury and inflammation are important contributing factors in the development of pancreatic cancer. This article attempts to understand the common pathways linking pancreatitis to pancreatic cancer.Recent Findings:Intracellular activation of both pancreatic enzymes and the transcription factor NF-kB are important mechanisms that induce acute pancreatitis. Recurrent pancreatic injury due to genetic susceptibility, environmental factors such as smoking, alcohol intake, and conditions such as obesity lead to increases in oxidative stress, impaired autophagy and constitutive activation of inflammatory pathways. These processes can stimulate pancreatic stellate cells, thereby increasing fibrosis and encouraging chronic disease development. Activation of oncogneic Kras mutations through inflammation, coupled with altered levels of tumor suppressor proteins (p53 and p16 can ultimately lead to development of pancreatic cancer. Summary:Although our understanding of pancreatitis and pancreatic cancer has tremendously increased over many years, much remains to be elucidated in terms of common pathways linking these conditions.

Identifying the areas at risk of ecosystem transformation and the main contributing factors to the risk is essential to assist ecological adaptation to climate change. We assessed the risk of ecosystem shifts in China using the projections of four global gridded vegetation models (GGVMs) and an aggregate metric. The results show that half of naturally vegetated land surface could be under moderate or severe risk at the end of the 21(st) century under the middle and high emission scenarios. The areas with high risk are the Tibetan Plateau region and an area extended northeastward from the Tibetan Plateau to northeast China. With the three major factors considered, the change in carbon stocks is the main contributing factor to the high risk of ecosystem shifts. The change in carbon fluxes is another important contributing factor under the high emission scenario. The change in water fluxes is a less dominant factor except for the Tibetan Plateau region under the high emission scenario. Although there is considerable uncertainty in the risk assessment, the geographic patterns of the risk are generally consistent across different scenarios. The results could help develop regional strategies for ecosystem conservation to cope with climate change.

In 66 patients subbivided into group of patients with coronary disease and group of control subjects the effect of radioactive waterbath and climatotherapy in Swieradow upon coronary disease risk factors was studied. The following risk factors were taken into account: cholesterol level, triglicerides, LDL, uric acid, the serum glucose level, arterial tension and weight. The results obtained indicate that the therapy with radon waters of Swieradow complexed with climatotherapy decreases the content of some coronary disease risk factors. The decrease of the urin acid in the serum, the lowering of arterial tension and decrease of body weight was noted. The lipid level in the serum did not change under effect of radioactive waters.

Full Text Available Different methods to elicit risk attitudes of individuals often provide differing results despite a common theory. Reasons for such inconsistencies may be the different influence of underlying factors in risk-taking decisions. In order to evaluate this conjecture, a better understanding of underlying factors across methods and decision contexts is desirable. In this paper we study the difference in result of two different risk elicitation methods by linking estimates of risk attitudes to gender, age and personality traits, which have been shown to be related. We also investigate the role of these factors during decision-making in a dilemma situation. For these two decision contexts we also investigate the decision-maker's physiological state during the decision, measured by heart rate variability (HRV, which we use as an indicator of emotional involvement. We found that the two elicitation methods provide different individual risk attitude measures which is partly reflected in a different gender effect between the methods. Personality traits explain only relatively little in terms of driving risk attitudes and the difference between methods. We also found that risk taking and the physiological state are related for one of the methods, suggesting that more emotionally involved individuals are more risk averse in the experiment. Finally, we found evidence that personality traits are connected to whether individuals made a decision in the dilemma situation, but risk attitudes and the physiological state were not indicative for the ability to decide in this decision context.

The number of women under community supervision in the United States has increased, and this population has a high risk for sexually transmitted infections (STIs). We examined STI prevalence and multiple risk factors among drug-involved women under community supervision in New York City. Data were from a randomized controlled trial testing the efficacy of a behavioral HIV/STI intervention (Women on the Road to Health [WORTH]) among drug-involved women in the community corrections system in New York City from 2009 to 2012. To be eligible for inclusion, women had to be under community supervision within the past 90 days, have used illicit drugs at least once in the past six months, and have unprotected sex at least once in the past 90 days. Participants completed a survey containing items on STI risk factors and were tested for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis. Multivariable regression was used to examine associations between risk factors and STI diagnosis. Of 333 women tested, 89 (26.7%) tested positive for an STI. Ten (3.0%) were positive for C. trachomatis, 4 (1.2%) for N. gonorrhoeae, and 77 (23.1%) for T. vaginalis. Women with any STI were more likely to be black (AOR: 2.02; 95% CI: 1.08-3.77), homeless in the past 90 days (AOR: 2.07; 95% CI: 1.01-4.26), arrested in the past 90 days (AOR: 1.97; 95% CI: 1.14-3.39), and have a greater number of sexual partners in the past 90 days (AOR: 1.24; 95% CI: 1.08-1.42). Drug-using women under community supervision have a high burden of STIs driven by multiple risk factors. Implementing STI screening, prevention, and treatment programs in community supervision settings could facilitate a reduction in STIs among this population.
Full Text Available Background Malnutrition in children under the age of five remains a major health problem, since half of mortality cases in this age group involve malnutrition. The 2006 earthquake caused destruction of physical, biological and socio-economic environments, potentially leading to malnutrition in Yogyakarta children. Objective To identify the prevalence and risk factors of malnutrition in Yogyakarta children under five years of age, one year after the 2006 earthquake. Methods We conducted a cross-sectional study among children aged 0 to 60 months in the Bambanglipuro Subdistrict, Bantul Regency, Yogyakarta from September to October 2007. Nutritional status was determined using weight for height Z-scores, according to the WHO 2006 Child Growth Standards. Results Out of 666 subjects, we found severe malnutrition, undernutrition, normal weight, and overweight status in 1.7%, 4.8%, 88.6% and 4.8%, respectively. By multivariate analysis, risk factors for malnutrition were not having been weighed during the previous three months (OR 0.35; 95% CI 0.1 to 0.8 and having acute respiratory infection in the previous two weeks (OR 1.99; 95% CI 1.1 to 3.8 Conclusion One year following the 2006 earthquake, acute respiratory infection in the previous two weeks and unmonitored growth in the previous three months were risk factors for malnutrition in children under five years.

This article deals with the development of risk management in the gas sector business: why a risk factor legal mention must precede any published financial information? Do gas companies have to face new risks? Is there specific risks bound to gas activities? Why companies want to master their risks? Is it mandatory or just a new habit? Do they expect a real benefit in return? These are the risk management questions that are analyzed in this article which is based on the public communication of 15 gas companies randomly selected over the world. The information comes from their annual reports or from documents available on their web sites. The intention of this document is not to be exhaustive or to make statistics but only to shade light on the risk factors of the gas sector. (J.S.)
Full Text Available BACKGROUND: Elucidating the role of the underlying risk factors for severe outcomes of the 2009 A/H1N1 influenza pandemic could be crucial to define priority risk groups in resource-limited settings in future pandemics. METHODS: We use individual-level clinical data on a large series of ARI (acute respiratory infection hospitalizations from a prospective surveillance system of the Mexican Social Security medical system to analyze clinical features at presentation, admission delays, selected comorbidities and receipt of seasonal vaccine on the risk of A/H1N1-related death. We considered ARI hospitalizations and inpatient-deaths, and recorded demographic, geographic, and medical information on individual patients during August-December, 2009. RESULTS: Seasonal influenza vaccination was associated with a reduced risk of death among A/H1N1 inpatients (OR = 0.43 (95% CI: 0.25, 0.74 after adjustment for age, gender, geography, antiviral treatment, admission delays, comorbidities and medical conditions. However, this result should be interpreted with caution as it could have been affected by factors not directly measured in our study. Moreover, the effect of antiviral treatment against A/H1N1 inpatient death did not reach statistical significance (OR = 0.56 (95% CI: 0.29, 1.10 probably because only 8.9% of A/H1N1 inpatients received antiviral treatment. Moreover, diabetes (OR = 1.6 and immune suppression (OR = 2.3 were statistically significant risk factors for death whereas asthmatic persons (OR = 0.3 or pregnant women (OR = 0.4 experienced a reduced fatality rate among A/H1N1 inpatients. We also observed an increased risk of death among A/H1N1 inpatients with admission delays >2 days after symptom onset (OR = 2.7. Similar associations were also observed for A/H1N1-negative inpatients. CONCLUSIONS: Geographical variation in identified medical risk factors including prevalence of diabetes and immune suppression may in part

Diarrhoea diseases are among the leading causes of morbidity and mortality in under-five-children (U-5C) in Nigeria. Inadequate safe water, sanitation, and hygiene account for the disease burden. Cases of diarrhoea still occur in high proportion in the study area despite government-oriented interventions. To determine the hygiene and sanitation risk factors predisposing U-5C to diarrhoea in Ibadan, Nigeria. Two hundred and twenty pairs of children, matched on age, were recruited as cases and controls over a period of 5 months in Ibadan. Questionnaire and observation checklist were used to obtain information on hygiene practices from caregivers/mothers and sanitation conditions in the households of 30% of the consenting mothers/caregivers. Data were analysed using descriptive and inferential statistics. Caregivers/mothers' mean ages were 31.3 ±7.5 (cases) and 30.6 ±6.0(controls) years. The risk of diarrhoea was significantly higher among children whose mothers did not wash hands with soap before food preparation (OR=3.0, pHygiene and sanitation conditions within households were risk factors for diarrhoea. This study revealed the feasibility of developing and implementing an adequate model to establish intervention priorities in sanitation in Ibadan, Nigeria.
Full Text Available Introduction: Diarrhea is a leading cause of mortality in children in developing countries and the condition is worse in slums. In order to provide effective preventive and management strategies, it is important to identify factors associated with the disease. This study was carried out to investigate the risk factors of diarrhea in children under five years of age in urban slums. Methods: Parents of all children under five years from the urban slums of Tansen municipality, Palpa, Nepal were interviewed using a standardized pretested questionnaire and proforma. Parental variables, environmental factors, and presence of diarrhea in those children in past three months were collected by trained enumerators and the data were analyzed with statistical software SPSS-10. Results: A total of 450 under five years children were enrolled in the study. There were 216 (48% male and 234 (52% female children with F:M ratio of 1.08:1. Occurrence of diarrhea was lower if the children were breast-fed for more than six months, well-nourished, used fountain water for drinking, or used boiled or treated water. Similarly, diarrhea prevalence was lower if father had a regular job, daily income in the family was more than one US dollar, there was a toilet in the house, practice of hand washing was followed before feeding or preparing food, or there was no child suffering from diarrhea in the neighborhood. Conclusion: There are a few variables that are significantly related to diarrhea in children under five years of age. In order to decrease the diarrheal episodes in children in the slums of the developing countries, priority could be given in the improvement of those variables.

There is limited research on sexually transmitted infections (STIs) among adolescents in Korea. The objective of this study was to explore the prevalence of and risk factors for STIs among Korean adolescents under probation. A cross-sectional analysis was conducted in one juvenile-delinquent center and five probation offices in Korea to determine the prevalence of STIs caused by the following pathogens: Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, herpes simplex virus (HSV), human immunodeficiency virus (HIV), Treponema pallidum, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, and Ureaplasma parvum. Of the 237 (208 male and 29 female) participating adolescents, 152 (64.1%) had a history of coitus. Overall, 133 (56.1%) subjects tested positive for at least one microorganism in their genitourinary tract. The most prevalent pathogen was U. urealyticum (24.7%, n = 65), followed by U. parvum (24.1%, n = 57), M. hominis (17.3%, n = 41), C. trachomatis (13.9%, n = 33), N. gonorrhoeae (1.7%, n = 4), T. vaginalis (0.8%, n = 2), and HSV (0.8%, n = 2). The prevalence of syphilis was 0.8% (n = 2). There were no reported cases of HIV infection. Fifty-four participants (35.5%) were positive with more than two pathogens. We did not find any significant difference between STIs and socioeconomic factors, behavioral factors or sexual practices. In conclusion, the prevalence of STIs among adolescents under probation was high. Systematic screening programs, more practical sexual education, and adequate provision of treatment are essential for the prevention and management of STIs among adolescents, especially those under probation.

Full Text Available Background: Vitamin K antagonists are widely used in the treatment and prevention of thromboembolic disease. However, these drugs can cause serious side effects, especially bleeding. This study aims to evaluate frequency and risk factors of both bleeding and asymptomatic overdose in North African patients undergoing Vitamin K antagonist therapy. Methods: We performed a cross-sectional study in patients undergoing Vitamin K antagonist therapy. A statistical analysis has been conducted to identify overdose and bleeding risk factors by using chi-square test (p < .05. Results: One hundred and eleven patients were included. We recorded 14 cases of bleeding and 26 cases of asymptomatic overdose. Advanced age, poor adherence, concomitant use of paracetamol and history of previous bleeding are significant risk factors of over-anticoagulation. An INR value over 6 at admission, a high therapeutic target range for INR, concomitant use of acetylsalicylic acid, lack of information on overdose signs and measures to be taken in case of bleeding were identified as risk factors for bleeding. Conclusion: Most of the risk factors identified in our study seem to be related to patients lack of information and education. These results highlight the importance of creating a therapeutic patient education program. Keywords: Vitamin K antagonist, Bleeding, Risk factor, Overdose

Increasing age is a risk factor for developing cancer. Yet, older people commonly underestimate this risk, are less likely to be aware of the early symptoms, and are more likely to be diagnosed with advanced stage cancer. Mass media are a key influence on the public's understanding health issues, including cancer risk. This study investigates how news media have represented age and other risk factors in the most common cancers over time. Eight hundred articles about the four most common cancers (breast, prostate, lung and colorectal) published within eight UK national newspapers in 2003, 2004, 2013 and 2014 were identified using the Nexis database. Relevant manifest content of articles was coded quantitatively and subjected to descriptive statistical analysis in SPSS to identify patterns across the data. Risk was presented in half of the articles but this was rarely discussed in any depth and around a quarter of all articles introduced more than one risk factor, irrespective of cancer site. Age was mentioned as a risk factor in approximately 12% of all articles and this varied by cancer site. Age was most frequently reported in relation to prostate cancer and least often in articles about lung cancer. Articles featuring personal narratives more frequently focused on younger people and this was more pronounced in non-celebrity stories; only 15% of non-celebrity narratives were about people over 60. Other common risks discussed were family history and genetics, smoking, diet, alcohol, and environmental factors. Family history and genetics together featured as the most common risk factors. Risk factor reporting varied by site and family history was most commonly associated with breast cancer, diet with bowel cancer and smoking with lung cancer. Age and older adults were largely obscured in media representation of cancer and cancer experience. Indeed common risk factors in general were rarely discussed in any depth. Our findings will usefully inform the development of
This paper presents several applications to interest rate risk management based on a two-factor continuous-time model of the term structure of interest rates previously presented in Moreno (1996). This model assumes that default free discount bond prices are determined by the time to maturity and two factors, the long-term interest rate and the spread (difference between the long-term rate and the short-term (instantaneous) riskless rate). Several new measures of ``generalized duration" are p...

To assess the risk factors associated with diarrhea among children below 5-years-old in Mukalla, Yemen, and compare with other studies. We conducted a case-control study on 200 children (100 cases and 100 controls) who attended the Maternity and Child Hospital, outpatient-clinics, and the Primary Health Care Centers in Al-Mukalla, Hadhramout, Yemen between February and April 2013. We found that the significant risk factors associated with diarrhea were crowded housing (odds ratio [OR] 2.02; p=0.02; confidence interval [CI] 1.03-4.01), incomplete vaccination of the child (OR=2.02; p=0.027; CI: 1.08-3.8), and recurrent diarrheal illness during the last 3 months (OR=6.61; p=0.001; CI: 3.41-12.90). Diarrheal diseases are strongly associated with incomplete vaccination, recurrent diarrheal disease, and crowded housing.

Full Text Available Introduction: Acute Respiratory Infection (ARI is a major cause of morbidity and mortality in developing countries in children especially in under-fives. Every year in the world, about 13 million under-5 children dies, 95% from developing countries; one third of total deaths are due to ARI. The aim of this study was to identify the significant risk factors for ARI in children less than five years of age living in rural areas of Central India.Methods: A hospital based case control study was undertaken to determine risk factors associated with respiratory tract infections in children. Children less than 5 years admitted in a pediatric ward with diagnosis of ARI were enrolled in the study as cases (n = 300 while the same number of controls (n = 300 were selected from neighborhood and were matched for age, sex and religion. Details of risk factors in cases and controls were recorded in pre-designed proforma. Results: A significant association was found between ARI and lack of breastfeeding, nutritional status, immunization status, delayed weaning, prelactal feeding, living in overcrowded conditions, mothers’ literacy status, low birth weight and prematurity. Among the environmental variables, inadequate ventilation, improper housing condition, exposure to indoor air pollution in form of combustion from fuel used for cooking were found as significant risk factors for ARI in under-fives.Conclusions: ARIs are affected by socio-demographic and socio-cultural risk factors, which can be modified with simple interventions. The various risk factors identified in this study were lack of breastfeeding, undernutrition, delayed weaning, overcrowding and prelactal feeding.

This retrospective study investigated the dependence of N-acetyl aspartate (NAA) ratios on risk factors for cerebral vasculopathy such as sex, age, hypertension, diabetes mellitus, carotid stenosis, and dyslipidaemia, which may have affected brain vessels and induced metabolic brain abnormalities prior to stroke. We hypothesise that in stroke patients metabolic alterations in the apparently normal contralateral brain are dependent on the presence or not of such risk factors. Fifty nine patients (31 male, 28 female: 58.8+/-16.1 years old) with cortical middle cerebral artery (MCA) territory infarction were included. Long echo time chemical shift imaging spectroscopy was carried out on a Siemens 1.5 T Magnetom Vision scanner using a multi-voxel PRESS technique. Metabolite ratios (NAA/choline, NAA/creatine, lactate/choline, etc) were studied using uni- and multivariate analyses with respect to common risk factors. The influence of age, stroke lesion size, and time since stroke was studied using a linear regression approach. Age, sex, and hypertension all appeared to individually influence metabolite ratios, although only hypertension was significant after multivariate analysis. In both basal ganglia and periventricular white matter regions in apparently normal contralateral brain, the NAA/choline ratio was significantly lower in hypertensive (1.37+/-0.16 and 1.50+/-0.19, respectively) than in normotensive patients (1.72+/-0.19 and 1.85+/-0.15, respectively). Regarding MCA infarction, contralateral tissue remote from the lesion behaves abnormally in the presence of hypertension, the NAA ratios in hypertensive patients being significantly lower. These data suggest that hypertension may compromise the use of contralateral tissue data as a reference for comparison with ischaemic tissue.

Serum samples from 248 adult dairy goats from 13 flocks with lowered fertility farmed in the Rio de Janeiro region of Brazil were examined for Leptospira antibodies by MAT with 24 serovars, cut off 100. A questionnaire was completed for each herd. Antibodies were detected in 20.8% of these goats, mainly to serovar Hardjo. Risk factors associated with seroprevalence to leptospirosis were the frequency of professional veterinary supervision (OR = 2.35), climate (OR = 2.63) and grazing for more than 2h a day. Flock factors as size, type of milking and offering of food supplementation, as well as the location and topography, the type of animal housing or the presence of silos did not significantly affect seroprevalence. We suggest that a successful control program for goat leptospirosis should include a complete investigation of herd management practices, which could influence in the occurrence of the infection.

Malnutrition is a common problem, especially in developing countries. Of the 11 million children under 5 who die each year in the developing countries mainly from preventable causes, the death of about 54% are either directly or indirectly attributable to malnutrition. The objectives of this study were to assess the prevalence and associated factors for underweight in rural Sindh. Methods: A cross-sectional survey was conducted in Jhangara Town, located in District Dadu, Sindh. Eight hundred children under 5 years of age were enrolled. A questionnaire was used to elicit required information and anthropometric measurements were made. Results: The overall prevalence for underweight was 54.3% in the study population, which was higher than the prevalence reported by PDHS 1990 - 91. In multivariate analysis, various factors for underweight were consanguinity (OR=1.5, 95% CI=1.0 - 2.07), low birth weight (parents perspective) (OR=1.6, 95% CI=1.08 - 2.16) and lack of breast-feeding (OR=2.7, 95% CI=1.19 - 6.17). Conclusion: Effective strategies to discourage consanguineous marriages between first cousins are required. Promoting breast feeding is another factor that should be incorporated while designing control strategies to reduce morbidity and mortality due to malnutrition in children (<5 years). (author)

The on-farm mortality of cows in cow-calf herds has a significant influence on the economic efficiency of the farm. It is also an indicator of suboptimal animal health and welfare. The present study analysed the registry data of beef cows in Estonia from the years 2013 to 2015. The datasets incorporated 8084 parturitions of primiparous cows and 21,283 parturitions of 9234 multiparous cows. A Weibull proportional hazard random effect model was used for risk factor analysis, in which the on-farm mortality, including death and euthanasia, was the event of interest. The first 30days post-calving were associated with the highest mortality hazard for primiparous and multiparous cows (including 28.9% and 21.1% of deaths, respectively). In multiparous cows, the lowest mortality hazard was confirmed for animals with parity of three to five, increasing significantly after that. Primiparous cows that did not have a stillborn calf had a significantly higher mortality hazard when calving over 44months of age compared to cows calving younger than 36months. Stillbirth and abortion were significant risk factors for mortality. Cows with dystocia experienced a higher mortality hazard, especially during the first week post-calving. In multiparous cows, a higher herd mean age at first calving was associated with a higher mortality hazard. This study highlights the fact that the early post-partum period and factors associated with calving, such as age at first calving, dystocia, stillbirth and abortion, are critical for beef cow survival.

Financial risky decisions and evaluations pervade many human everyday activities. Scientific research in such decision-making typically explores the influence of socio-economic and cognitive factors on financial behavior. However, very little research has explored the holistic influence of contextual, emotional, and hormonal factors on preferences for risk in insurance and investment behaviors. Accordingly, the goal of this review article is to address the complexity of individual risky behavior and its underlying psychological factors, as well as to critically examine current regulations on financial behavior.

Full Text Available BACKGROUND: Exertional rhabdomyolysis syndrome is recognised in many athletic horse breeds and in recent years specific forms of the syndrome have been identified. However, although Standardbred horses are used worldwide for racing, there is a paucity of information about the epidemiological and performance-related aspects of the syndrome in this breed. The objectives of this study therefore were to determine the incidence, risk factors and performance effects of exertional rhabdomyolysis syndrome in Standardbred trotters and to compare the epidemiology and genetics of the syndrome with that in other breeds. METHODOLOGY/PRINCIPAL FINDINGS: A questionnaire-based case-control study (with analysis of online race records was conducted following identification of horses that were determined susceptible to exertional rhabdomyolysis (based on serum biochemistry from a total of 683 horses in 22 yards. Thirty six exertional rhabdomyolysis-susceptible horses were subsequently genotyped for the skeletal muscle glycogen synthase (GYS1 mutation responsible for type 1 polysaccharide storage myopathy. A total of 44 susceptible horses was reported, resulting in an annual incidence of 6.4 (95% CI 4.6-8.2% per 100 horses. Female horses were at significantly greater risk than males (odds ratio 7.1; 95% CI 2.1-23.4; p = 0.001 and nervous horses were at a greater risk than horses with calm or average temperaments (odds ratio 7.9; 95% CI 2.3-27.0; p = 0.001. Rhabdomyolysis-susceptible cases performed better from standstill starts (p = 0.04 than controls and had a higher percentage of wins (p = 0.006. All exertional rhabdomyolysis-susceptible horses tested were negative for the R309H GYS1 mutation. CONCLUSIONS/SIGNIFICANCE: Exertional rhabdomyolysis syndrome in Standardbred horses has a similar incidence and risk factors to the syndrome in Thoroughbred horses. If the disorder has a genetic basis in Standardbreds, improved performance in susceptible animals may be

Poor treatment adherence leading to risk of drug resistance, treatment failure, relapse, death and persistent infectiousness remains an impediment to the tuberculosis control programmes. The objective of the study was to identify predictors of default among new smear positive TB patients registered for treatment to suggest possible interventions to set right the problems to sustain and enhance the programme performance. Twenty districts selected from six states were assigned to six strata formed, considering the geographic, socio-cultural and demographic setup of the area. New smear positive patients registered for treatment in two consecutive quarters during III quarter 2004 to III quarter 2005 formed the retrospective study cohort. Case control analysis was done including defaulted patients as "cases" and equal number of age and sex matched patients completing treatment as "controls". The presence and degree of association between default and determinant factors was computed through univariate and multivariate logistic regression analysis. Data collection was through patient interviews using pre-tested semi structured questionnaire and review of treatment related records. Information on a wide range of socio demographic and patient related factors was obtained. Among the 687 defaulted and equal numbers of patients in completed group, 389 and 540 patients respectively were satisfactorily interviewed.

Full Text Available Poor treatment adherence leading to risk of drug resistance, treatment failure, relapse, death and persistent infectiousness remains an impediment to the tuberculosis control programmes. The objective of the study was to identify predictors of default among new smear positive TB patients registered for treatment to suggest possible interventions to set right the problems to sustain and enhance the programme performance.Twenty districts selected from six states were assigned to six strata formed, considering the geographic, socio-cultural and demographic setup of the area. New smear positive patients registered for treatment in two consecutive quarters during III quarter 2004 to III quarter 2005 formed the retrospective study cohort. Case control analysis was done including defaulted patients as "cases" and equal number of age and sex matched patients completing treatment as "controls". The presence and degree of association between default and determinant factors was computed through univariate and multivariate logistic regression analysis. Data collection was through patient interviews using pre-tested semi structured questionnaire and review of treatment related records. Information on a wide range of socio demographic and patient related factors was obtained. Among the 687 defaulted and equal numbers of patients in completed group, 389 and 540 patients respectively were satisfactorily interviewed. In the logistic regression analysis, factors independently associated with default were alcoholism [AOR-1.72 (1.23-2.44], illiteracy [AOR-1.40 (1.03-1.92], having other commitments during treatment [AOR-3.22 (1.1-9.09], inadequate knowledge of TB [AOR-1.88(1.35-2.63], poor patient provider interaction [AOR-1.72(1.23-2.44], lack of support from health staff [AOR-1.93(1.41-2.64], having instances of missed doses [AOR-2.56(1.82-3.57], side effects to anti TB drugs [AOR-2.55 (1.87-3.47] and dissatisfaction with services provided [AOR-1.73 (1

Full Text Available Introduction: Pneumonia is major cause of mortality among acute respiratory infections, killing up to 5 million of children below the age of 5 years annually in developing countries. Total 50% out-patients cases in Sudan are children while 30% of children admissions are due to pneumonia. Every year, the number of deaths in infant and children below the age of 5 years is reported to be 12 million. Objectives: The aim of this study is to find out the pneumonia risks in Sudan among children <5 years and to establish a baseline data and statistical information about pneumonia in the age group for future use. Study design and Setting: A hospital based descriptive study was conducted among children <5 years at Mohamed Al-Amin Hamid Pediatric Hospital in February 2017. Methods: Parents of 40 children <5 years admitted to the hospital during the study period completed the constructed questionnaire after obtaining informed consents from each of them. Data was then analyzed. Results: Children in this study consisted of 27 (57.50% males and 13 (42.5% females. Factors found to have association with pneumonia include low socio-economic status and low educational level of mothers. Conclusion and Recommendations: The study concluded that the pneumonia is more prevalent in children less than one year. Factors found to have association with pneumonia include low socioeconomic status and low educational level of mothers admitted to Mohamed Al-Amin pediatric hospital in Omdurman locality. It was recommended to have an early diagnosis and treatment of pneumonia. Community health education and completion of the immunization program are recommended to decrease the infection.

Urban trees help towns to cope with climate warming by cooling both air and surfaces. The challenges imposed by the urban environment, with special reference to low water availability due to the presence of extensive pavements, result in high rates of mortality of street trees, that can be increased by climatic extremes. We investigated the water relations and xylem hydraulic safety/efficiency of Quercus ilex trees growing at urban sites with different percentages of surrounding impervious pavements. Seasonal changes of plant water potential and gas exchange, vulnerability to cavitation and embolism level, and morpho-anatomical traits were measured. We found patterns of increasing water stress and vulnerability to drought at increasing percentages of impervious pavement cover, with a consequent reduction in gas exchange rates, decreased safety margins toward embolism development, and increased vulnerability to cavitation, suggesting the occurrence of stress-induced hydraulic deterioration. The amount of impermeable surface and chronic exposure to water stress influence the site-specific risk of drought-induced dieback of urban trees under extreme drought. Besides providing directions for management of green spaces in towns, our data suggest that xylem hydraulics is key to a full understanding of the responses of urban trees to global change. © 2014 The Authors.

To describe the spatial pattern in under-5 mortality rates in the Basse Health and Demographic Surveillance System (BHDSS) and to test for associations between under-5 deaths and biodemographic and socio-economic risk factors. Using data on child survival from 2007 to 2011 in the BHDSS, we mapped under-5 mortality by km(2) . We tested for spatial clustering of high or low death rates using Kulldorff's spatial scan statistic. Associations between child death and a variety of biodemographic and socio-economic factors were assessed with Cox proportional hazards models, and deviance residuals from the best-fitting model were tested for spatial clustering. The overall death rate among children under 5 was 0.0195 deaths per child-year. We found two spatial clusters of high death rates and one spatial cluster of low death rates; children in the two high clusters died at a rate of 0.0264 and 0.0292 deaths per child-year, while in the low cluster, the rate was 0.0144 deaths per child-year. We also found that children born to Fula mothers experienced, on average, a higher hazard of death, whereas children born in the households in the upper two quintiles of asset ownership experienced, on average, a lower hazard of death. After accounting for the spatial distribution of biodemographic and socio-economic characteristics, we found no residual spatial pattern in child mortality risk. This study demonstrates that significant inequality in under-5 death rates can occur within a relatively small area (1100 km(2) ). Risks of under-5 mortality were associated with mother's ethnicity and household wealth. If high mortality clusters persist, then equity concerns may require additional public health efforts in those areas. © 2015 John Wiley & Sons Ltd.

Postoperative nausea and vomiting belong to fairly frequent postoperative complications, but they occupy a distant position on the list of complications, which most probably result from a general conviction that they do not pose a direct threat to patients. The objective of this work is specification of factors facilitating occurrence of postoperative nausea and vomiting, and determination of frequency of their occurrence in patients operated under general anesthesia. Questionnaire about the occurrence of postoperative nausea and vomiting (PONV), was carried out and included 253 adult sick persons (102 female and 151 male patients), in the age between 23-76 (average 42.3 +/- 6.1 years), who had undergone operative procedure in the field of abdominal and urology surgery, orthopedic, thyroid surgery and laryngological, ophthalmology and plastic surgery, under general anesthesia. The questionnaire form included preoperative characteristics of a patient (age, sex, smoking, motion sickness and migraine headaches in history, and PONV occurring earlier), type of operative procedure, used anesthetic agents, and analgesic agents applied in postoperative analgesia. The anesthesiologist administering anesthetic was not informed about the investigation carried out and did not receive any additional pieces of advice regarding the type of applied anesthetic agents or the method of conducting postoperative analgesia. Visual Analogue Scale (VAS) was used in the evaluation of nausea. Nausea and vomiting were assessed every two hours within the first postoperative 12 hours and every 4 hours for the next 24 hours. Nausea and vomiting were treated as two separate complications. Nausea itself occurred in 22.7% of patients; whereas vomiting in 13.2%. Both symptoms occurred in 14.2% of patients. Nausea occurred 4.1 +/- 0.8 hours after operation; whereas vomiting after 5.3 +/- 1.1 hours. Women suffered more often than men from (R = 0.678 p patients suffering from PONV earlier (R = 0

Full Text Available We analyzed parameters characterizing mineral balance in a body and dental state in two groups of healthy men (n = 15 in each, aged 34.7 ± 0.6 in hot and humid marine climate conditions; one group was made of people undergoing acclimatization, the second one consisted of local population. We assessed working conditions and their category, and metrological data with determining environmental thermal load (ETL-index. Both groups worked outdoors; their labor had IIb category; they had to work overtime and under increased psy-choemotional loads; their working conditions differed as per nutrition and accommodation. When people from both groups had to work beyond their permanent location, their nutrition was represented by individual rations. Labor hardness was assessed as 3.2; labor intensity, as 3.2. Daytime temperature reached 30,0 С, relative air humidity was 77.3 ± 2.6 %, wind speed was 4.3 ± 0.3 m/sec. Microclimate was assessed as having 3.1 hazard category. Overall, working conditions were assessed as hazardous (3.3 hazard category. Electrolyte balance in a body was violated and it was proved by ower contents of K, Na, and Cl in blood serum; it was more apparent in people who were undergoing acclimatization. 70.0 % of local people had Ca contents in blood serum lower than the physiological standard. Lower Ca and increased P contents in blood serum were also detected in those undergoing acclimatization which could be evidence that Ca was washed out of a body and greater risk of dental caries occurred. As per observation dynamics we detected the following processes in people undergoing acclimatization: pH saliva and its mineralizing function shifting to acidity, salivation rate, and lower enamel resistance; they proved there was a growth in dental solid tissues demineralization. These parameters corresponded to those detected in local population. It calls for primary prevention activities aimed at fighting caries of dental solid tissues.

Diarrhoeal diseases remain an important cause of mortality and morbidity among children, particularly in low- and middle-income countries. In Senegal, diarrhoea is responsible for 15% of all deaths in children under the age of five and is the third leading cause of childhood deaths. For targeted planning and implementation of prevention strategies, a context-specific understanding of the determinants of diarrhoeal diseases is needed. The aim of this study was to identify risk factors of diarrhoeal diseases in children under the age of five in Mbour, Senegal. Between February and March 2014, a cross-sectional survey was conducted in four zones of Mbour to estimate the burden of diarrhoeal diseases (i.e. diarrhoea episodes in the 2 weeks preceding the survey) and associated risk factors. The zones covered urban central, peri-central, north peripheral and south peripheral areas. Overall, 596 households were surveyed by a questionnaire, yielding information on sociodemographic, environmental and hygiene behavioural factors. Univariable and multivariable logistic regression analyses were used to identify risk factors associated with the occurrence of diarrhoea. The reported prevalence of diarrhoea among children under the age of five during the 2 weeks preceding the survey was 26%. Without adjustment, the highest diarrhoea prevalence rates were observed in the peri-central (44.8%) and urban central zones (36.3%). Multivariable regression revealed significant associations between diarrhoeal diseases and unemployment of mothers (adjusted odds ratio [aOR] = 1.62, 95% confidence interval [CI]: 1.18-2.23), use of open bags for storing household waste (aOR = 1.75, 95% CI: 1.00-3.02), evacuation of household waste in public streets (aOR = 2.07, 95% CI: 1.20-3.55), no treatment of stored drinking water (aOR = 1.69, 95% CI: 1.11-2.56) and use of shared toilets (aOR = 1.69, 95% CI: 1.11-2.56). We found a high prevalence of diarrhoea in children under the age of five

As a measure of how prosocial behavior depends on social distance, social discounting is defined as the decrease in generosity between the decision maker and the recipient as the social distance increases. While risk is a ubiquitous part of modern life, there is limited research on the relationship between risk and prosocial behavior. In the present experiment, we empirically test whether risk has an influence on social discounting. We use the choice titration procedure to examine this effect. Our data show that independent of risk, participants are less eager to forego money and exhibit more selfishness toward a specific person when the social distance increases; these findings are reflected in the hyperbolic model. Interestingly, risk influences the shape of the social discounting function, which is reflected in the notable different discount rates. Individuals who make decisions under risk yield a smaller discount rate than those who make decisions without risk, i.e., under risk subjects reduce less their generosity as a function of the social distance. Furthermore, this distinct type of generosity occurs typically among individuals with 10-distance recipients but not with the closest- and furthest-social-distance recipients.

Logistic regression (LR) analysis is the most common statistical methodology to find out the determinants of childhood mortality. However, the significant predictors cannot be ranked according to their influence on the response variable. Multiple classification (MC) analysis can be applied to identify the significant predictors with a priority index which helps to rank the predictors. The main objective of the study is to find the socio-demographic determinants of childhood mortality at neonatal, post-neonatal, and post-infant period by fitting LR model as well as to rank those through MC analysis. The study is conducted using the data of Bangladesh Demographic and Health Survey 2007 where birth and death information of children were collected from their mothers. Three dichotomous response variables are constructed from children age at death to fit the LR and MC models. Socio-economic and demographic variables significantly associated with the response variables separately are considered in LR and MC analyses. Both the LR and MC models identified the same significant predictors for specific childhood mortality. For both the neonatal and child mortality, biological factors of children, regional settings, and parents socio-economic status are found as 1st, 2nd, and 3rd significant groups of predictors respectively. Mother education and household environment are detected as major significant predictors of post-neonatal mortality. This study shows that MC analysis with or without LR analysis can be applied to detect determinants with rank which help the policy makers taking initiatives on a priority basis. (author)

Full Text Available Diarrheal disease remains a leading cause of death in children in low-income countries. We investigated the etiology, risk factors and effects on nutritional status of severe diarrhea in children from two districts in Madagascar.We performed a matched case-control study in 2011 to 2014, on children under the age of five years from Moramanga and Antananarivo. The cases were children hospitalized for severe diarrhea and the controls were children without diarrhea selected at random from the community. Stool samples were collected from both groups. Anthropometric measurements were made during follow-up visits about one and two months after enrolment.We enrolled 199 cases and 199 controls. Rotavirus infection was the most frequently detected cause of diarrhea. It was strongly associated with severe diarrhea (OR: 58.3; 95% CI: 7.7-439.9, accounting for 42.4% (95% CI: 37.6-43.1 of severe diarrhea cases. At the household level, possession of cattle (OR = 0.3; 95% CI: 0.1-0.6 and living in a house with electricity (OR = 0.4; 95% CI: 0.2-0.8 were protective factors. The presence of garbage around the house was a risk factor for severe diarrhea (OR = 3.2; 95% CI: 1.9-5.4. We found no significant association between severe diarrhea and the nutritional status of the children at follow-up visits, but evident wasting at enrolment was associated with a higher risk of severe diarrhea (OR = 9; 95% CI: 4.5-17.9.Severe childhood diarrhea is mostly caused by rotavirus infection. An anti-rotavirus vaccine has already been introduced in Madagascar and should be promoted more widely. However, post-licensing surveillance is required. Interventions to improve the nutritional status of children, preventive measures focused on household and personal hygiene and nutritional rehabilitation during severe diarrheal disease should be reinforced.

Full Text Available The foundation for future firm development is investment. Agents have a risk aversion requiring higher returns as the risks associated with the project will be greater. The investment decision determines the market firm's affirmation, increasing the market share, dominating the market. Making an investment at a certain point will determine certain cash flows throughout the life of the project, and a residual value can be obtained when it is taken out of service. The flows and payments for the investment project can be more easily tracked if we are proposing a constant update rate. We will be able to analyze, based on various factors, three techniques for determining the discount rate for investment projects: the opportunity cost, the risk-free rate, and a series of risk premiums, the weighted average cost of capital. People without financial training make value judgments for investment projects based on other market opportunities, comparing the returns that any investment offers to other pay options. An investor has a sum of money he wants to make - if he does not invest in a project, he will invest in another, that will bring him a certain amount of money, choosing the most advantageous project by comparison. All projects are characterized by identical risks, and the agents are considered indifferent to the risks. The answer given by financial theory and practice to the disadvantage of rates in the opportunity cost category is the discount rate calculated as a sum of the risk-free rate and a risk premium, defining the risk as a factor whose action may cause a possible decrease in cash of the available flows. Higher objectivity is presented by the opportunity cost update rates of update because it refers to known variables but cannot be perfectly matched to the performance of the investment process.

Full Text Available Abstract Background United Nations High Commissioner for Refugees (UNHCR refugee camps are located predominantly in rural areas of Africa and Asia in protracted or post-emergency contexts. Recognizing the importance of malaria, pneumonia and diarrheal diseases as major causes of child morbidity and mortality in refugee camps, we analyzed data from the UNHCR Health Information System (HIS to estimate incidence and risk factors for these diseases in refugee children younger than five years of age. Methods Data from 90 UNHCR camps in 16 countries, including morbidity, mortality, health services and refugee health status, were obtained from the UNHCR HIS for the period January 2006 to February 2010. Monthly camp-level data were aggregated to yearly estimates for analysis and stratified by location in Africa (including Yemen or Asia. Poisson regression models with random effects were constructed to identify factors associated with malaria, pneumonia and diarrheal diseases. Spatial patterns in the incidence of malaria, pneumonia and diarrheal diseases were mapped to identify regional heterogeneities. Results Malaria and pneumonia were the two most common causes of mortality, with confirmed malaria and pneumonia each accounting for 20% of child deaths. Suspected and confirmed malaria accounted for 23% of child morbidity and pneumonia accounted for 17% of child morbidity. Diarrheal diseases were the cause of 7% of deaths and 10% of morbidity in children under five. Mean under-five incidence rates across all refugee camps by region were: malaria [Africa 84.7 cases/1000 U5 population/month (95% CI 67.5-102.0, Asia 2.2/1000/month (95% CI 1.4-3.0]; pneumonia [Africa 59.2/1000/month (95% CI 49.8-68.7, Asia 254.5/1000/month (95% CI 207.1-301.8]; and diarrheal disease [Africa 35.5/1000/month (95% CI 28.7-42.4, Asia 69.2/1000/month (95% CI 61.0-77.5].

The risk factors and impact of retained fetal membranes (RFM) on productive and reproductive performance of crossbred cattle, Zebu cattle, and Murrah buffalos were evaluated using data spread over 12 years. Multivariable logistic regression model was used to identify risk factors and to quantify their odds ratio (OR). Overall incidence of RFM in crossbred cattle, Zebu cattle, and Murrah buffalos were 26, 16, and 13 %, respectively; and significant risk factors for RFM in crossbred cattle were abortion (OR = 3.9), dead calf (OR = 4.1), dystocia (OR = 4.3), pluriparity (OR = 1.5), and shorter gestation length (OR = 4.3). In Zebu cattle, abortion (OR = 4.0), dead calf (OR = 3.7), dystocia (OR = 3.9), lower birth weight of calf (OR = 1.6), and shorter gestation length (OR = 6.4) were significant risk factors for RFM. In Murrah buffalos, abortion (OR = 19.2), dead calf (OR = 4.4), dystocia (OR = 4.7), pluriparity (OR = 1.7), shorter gestation length (OR = 12.7), and calving during summer season (OR = 1.8) were the risk factors for RFM. Although the occurrence of RFM did not affect fertility parameters, a significant (P < 0.05) decrease in 305-day milk yield and total milk yield was observed in RFM-affected crossbred cattle. Taken together, it may be concluded that increased parity, abnormal calving, and short gestation length were the main risk factors for RFM in dairy bovine.

As the population ages, diseases of the elderly are becoming more common, including osteoporosis. Ways to assess the risk of fracture and the distribution and effects of known risk factors for osteoporosis will be important in planning for future healthcare needs, as well as in the development of preventive strategies. The study population included 6029 men and women aged 20-90 who underwent examination in the second follow-up wave of the Study of Health in Pomerania (SHIP-2) or in the basal SHIP-Trend Study. The risk of fracture was estimated on the basis of quantitative ultrasonography of the calcaneus. Prior fractures and risk factors for osteoporosis were ascertained in standardized interviews. 4.6% of the male subjects and 10.6% of the female subjects were judged to have an elevated risk of fracture. The corresponding percentages among subjects over age 65 were 8.8% for men and 28.2% for women. Even among subjects under age 55, risk factors for osteoporosis were associated with lower bone stiffness: the mean stiffness index was 103/98 (men/women) without risk factors, 99/96 with one risk factor, and 93/95 with more than one risk factor. Logistic regression analysis yielded an odds ratio of 1.89 (95% confidence interval: 1.44-2.50; p<0.01) for prevalent fractures among subjects aged 75 and older compared to subjects under age 55. The data indicate a high prevalence of osteoporosis from age 65 onward. These findings are consistent with those of other studies from Germany and across Europe. Younger men and women should already begin taking steps to counteract modifiable risk factors.

Financial risky decisions and evaluations pervade many human everyday activities. Scientific research in such decision-making typically explores the influence of socio-economic and cognitive factors on financial behavior. However, very little research has explored the holistic influence of contextual, emotional, and hormonal factors on preferences for risk in insurance and investment behaviors. Accordingly, the goal of this review article is to address the complexity of individual risky behav...

The aim of this study was to evaluate whether increased crown-to-implant (C/I) ratio influences implant stability or not under proper healthy control of peri-implant mucosa. The hypothesis of this study is that implant stability can be maintained despite High C/I, under appropriate plaque control. Five male Beagle-Labrador hybrid dogs (2 years old) were used. Their bilateral mandibular premolar extraction was performed. After allowing 12 weeks for bone healing, 3 types of vertical marginal bone loss were simultaneously prepared randomly. Then, 30 titanium implants were placed in the edentulous areas and defined as High C/I, Mid C/I and Low C/I groups. This time point was designated as the baseline (0 Week). Twelve weeks after implant placement, metal superstructures were cemented to the implants and an occlusal plate was set at the opposite side. At the same time, Calcein green was injected for remodeling evaluation. Implants were loaded by feeding the dogs a hard pellet diet. Tooth brushing was performed 5 days per week during the study to maintain healthy peri-implant mucosa. Twenty-four weeks following implant placement, the interface structure was evaluated clinically, radiologically, and histologically. Implant stability quotient (ISQ) increased with time in all 3 groups, without any significant correlation with the C/I value (p >0.05). Moreover, mean marginal bone loss adjacent around implants in all 3 groups ranged between 0.11 and 0.19 mm, with no significant difference (p >0.05). Many fluorescence-labeled bones are shown in the High C/I group. It is considered that high remodeling activity prevent marginal bone loss in the High C/I group and this may provide favorable implant stability under proper plaque control. These findings suggest that increased C/I may not be a risk factor for implant failure if the peri-implant mucosa is kept healthy, as was the case in this animal model.

Schizophrenia is a multifactorial, neurodevelopmental disorder caused by a combination of genetic and environmental risk factors. Disturbances of brain development begin prenatally, while different environmental insults further affect postnatal brain maturation during childhood and adolescence. Genome-wide association studies (GWAS) have succeeded in identifying hundreds of new risk variants for common, multifactorial diseases. In schizophrenia research, GWAS have found several rare copy number variants that considerably increase the risk of schizophrenia, and have shown an association between schizophrenia and the major histocompatibility complex. Research on environmental risk factors in recent years has provided new information particularly on risk factors related to pregnancy and childhood rearing environment. Gene-environment interactions have become a central research topic. There is evidence that genetically susceptible children are more vulnerable to the effects of unstable childhood rearing environment and other environmental risk factors.

Workers employed in the exam-ined branches had to work under exposure to production aerosols with complex structure and they working conditions had 3.2–3.4 hazard degree. We showed that occupational factors exerted negative influence on workers' health as they caused occupational bronchitis development, grave complications, and frequent associated diseases evolvement. The paper dwells on the results of our research on lipid peroxidation products content in workers exposed to production aerosols. We detected increased activity of free radical oxidation caused by impacts exerted by production aerosols; here we revealed that growth in lipid peroxidation products depended on duration of work under hazardous conditions. We set a goal to detect correlation between polymorph gene types of xenobiotics transformation enzymes and occupational bronchitis evolvement via poly-merase chain reaction technique; to achieve this, we analyzed polymorphic locuses in a group of sick workers (131 people and healthy ones (156 people. We determined genetic markers which had protective significance in terms of occupational bronchitis evolvement risk. The research results prove that occupational bronchitis nature and peculiarities of its clinic pic-ture are determined both by occupational impacts and individual features of a worker' s body.
Full Text Available Background: As infected children represent a large proportion of the pool from which tuberculosis (TB cases will arise and its associated risk factors that influence TB infection are basic cause for burden of TB. Aim: This study was to determine the prevalence of latent TB and associated risk factors in children less than 5 year of age in Karachi, Pakistan. Setting and Design: Cross-sectional study and it was conducted in tertiary care hospital in Karachi. Materials and Methods: In this study, children who were living in contact with individuals who had proven smear-positive pulmonary TB cases were investigated. A tuberculin skin test (TST was performed on each child. TST sizes ≥5 and 10 mm, respectively, were considered positive. Statistical Analysis: A random effects logistic regression model, which takes into account the clustering of contacts within households, was used to assess the relationship between the tuberculin response of the contact and risk factors. Results are reported as unadjusted and adjusted odds ratios and their 95% confidence intervals. The likelihood ratio test was used to assess the overall significance of risk factors, tests for trend, and tests for interaction. Results: The distribution of TST responses followed a bimodal pattern, with 135 (35% children presenting a palpable induration. The risk of positive TST response in the child increased with the geographic proximity of the child to the individual with TB within the household and with the degree of activities shared with the individual with TB. Nutritional status and presence of a bacille Calmette-Guérin (BCG scar were not independent risk factors for TST positivity in this population. On multivariate analysis, the effect of geographic proximity to the individual with TB, household size, and duration of cough in the index case persisted for TST responses ≥5 mm. Conclusions: Positive TST in a child reflects most probably TB infection rather than previous BCG

While many handguns are used in crime each year in the USA, most are not. We conducted this study to identify factors present at the time of a handgun’s most recent retail sale that were associated with its subsequent use in crime under circumstances suggesting that the handgun had been trafficked—purchased with the intent of diverting it to criminal use. Handguns acquired in multiple-gun purchases were of particular interest. Using data for 180,321 handguns purchased from federally licensed retailers in California in 1996, we studied attributes of the handguns, the retailers selling them, the purchasers, and the sales transactions. Our outcome measure was a handgun’s recovery by a police agency, followed by a gun ownership trace, conducted by the Bureau of Alcohol, Tobacco, Firearms and Explosives, that determined (a) that the recovery had occurred within 3 years of the handgun’s most recent purchase from a licensed retailer and (b) that the person who possessed the gun when it was recovered by police was not its most recent purchaser. Altogether, 722 handguns were recovered and had trace results that met the additional criteria. Handguns acquired in multiple-gun, same-day transactions were more likely to be traced than were single-purchase handguns (odds ratio [OR] 1.33, 95% confidence intervals [CI] 1.08 to 1.63). This was not the case for multiple-purchase handguns defined more broadly as multiple handguns purchased by one individual over any 30-day period as used in “one-gun-a-month” laws. Bivariate regressions indicated increased risk of a handgun being traced when it sold new for $150 or less (OR 4.28, 95% CI 3.59 to 5.11) or had been purchased by a woman (OR 2.02, 95% CI 1.62 to 2.52). Handguns sold by retailers who also had a relatively high proportion (≥2%) of purchases denied because the prospective purchasers were prohibited from owning firearms were more likely to be traced than were those sold by other retailers (OR 4.09, 95% CI 3.39 to

Objective: To determine the adverse drug reaction (ADR) profile of non-ionic iodinated contrast media in populations with underlying diseases and risk factors and to provide guidance for more safe and rational use of iodinated contrast media (ICMs) in the clinic. Methods: Data from 120,822 cases who underwent enhanced CT examination in our hospital from January 2014 to March 2016 were collected. A standardized case report form was used for data collection and analysis. Results: The incidence of ADRs was 0.4% and 0.44% in patients with and without underlying diseases, respectively (p = 0.378). Risk factor analysis revealed that patients with asthma had the highest incidence of ADRs, followed by patients with cardiac insufficiency and patients who were aged had the lowest incidence. There was a low incidence of ADRs in patients under metformin (0.36%) and β-adrenaline receptor antagonist (0.20%) medication. The incidence was the highest in patients with previous ADRs to ICMs (7.17%) and the lowest in those with a history of ICM usage but no previous reactions (0.32%). ADRs were more common in patients at high risk at a higher injection dose (≥100 ml; p < 0.01) and speed (≥5 ml s−1; p < 0.01). Conclusion: The incidence of ADRs was extremely low in patients regardless of underlying diseases. Some high-risk factors have certain correlations with the occurrence of ADRs. Particular attention should be given to patients at high risk when performing enhanced CT examination. Advances in knowledge: The correlation between various risk factors and underlying diseases and ADRs was comprehensively analyzed in a large-scale population. PMID:27928926

A broad survey is given of risk factors for neoplasms. The main carcinogenic substances (including also ionizing radiation and air pollution) are listed, and are correlated with the risk factors for various cancers most frequently explained and discussed in the literature. The study is intended to serve as a basis for a general assessment of the incidence of neoplasms in children, and of cancer mortality in the entire population of Bavaria in the years 1983-1989, or 1979-1988, respectively, with the principal idea of drawing up an environment-related health survey. The study therefore takes into account not only ionizing radiation as a main risk factor, but also other risk factors detectable within the ecologic context, as e.g. industrial installations and their effects, refuse incineration plants or waste dumps, or the social status.

: To investigate perioperative and postoperative bleeding, complications in patients under therapy with anticoagulant or antiplatelet drugs submitted to oral surgery. To evaluate the risk of bleeding and safety for dental surgery, a retrospective chart review was performed. Medical and dental records of patients taking oral antithrombotic drugs undergoing dental surgery between 2010 and 2015 were reviewed. Results were statistically analyzed using Fisher's exact test, t test or the χ test. One hundred and seventy-nine patients underwent 293 surgical procedures. A total of eight cases of perioperative and 12 episodes of postoperative bleeding were documented. The complications were generally managed with local measures and did not require hospitalization. We found significant association of postoperative hemorrhage with increased perioperative bleeding (P = 0.043) and combination of anticoagulant and antiplatelet therapy (P bleeding is 8.8 times bigger than procedures without perioperative bleeding. Dental surgery in patients under antithrombotic therapy might be carried out without altering the regimen because of low risk of perioperative and postoperative bleeding. However, patients with increased perioperative bleeding should be closely followed up because of postoperative complications risk.

Various risk factors were identified having significant association with occurrence of bovine brucellosis in dairy herds of peri-urban areas. Materials and Methods: Five randomly selected peri-uban areas of six cities of Gujarat were included in the present study. Five randomly selected dairy herds under intensive system of production from each selected peri-urban area were included for further investigation. In total, 199 bulk and 582 individual milk samples were screened by milk-ELISA. Forty three different risk factors were identified and grouped into four major categories as general characteristics of farms, introduction of infection to farms, management systems of farms and exposure of disease. Further, their distribution and association with prevalence of bovine brucellosis was studied. Results: The overall herd and animal prevalence in peri-urban areas was 33.70 and 11.90%, respectively. Out of 11 risk factors on general characteristics of dairy farms, only five (herd size, type of animals, type of breed, age of owner and knowledge gained by owners showed significant (p<0.05 association with occurrence of bovine brucellosis. None of risk factors on introduction of infection to farms (n=6 and management systems of farms (n=11 was found significantly associated with occurrence of brucellosis. Among risk factors on exposure of disease (n=15, history of abortion, retention of placenta, still birth and metritis/endometritis showed significant (p<0.05 association with prevalence of bovine brucellosis. Conclusion: It was concluded that prevalence of bovine brucellosis in dairy herds under intensive system of production in peri-urban areas of Gujarat was comparatively higher than reported overall prevalence of brucellosis.

Lower education level could be a risk factor for higher peritoneal dialysis (PD)-associated peritonitis, potentially resulting in technique failure. This study evaluated the influence of lower education level on the development of peritonitis, technique failure, and overall mortality. Patients over 18 years of age who started PD at Seoul National University Hospital between 2000 and 2012 with information on the academic background were enrolled. Patients were divided into three groups: middle school or lower (academic year≤9, n = 102), high school (912, n = 324). Outcomes were analyzed using Cox proportional hazards models and competing risk regression. A total of 655 incident PD patients (60.9% male, age 48.4±14.1 years) were analyzed. During follow-up for 41 (interquartile range, 20-65) months, 255 patients (38.9%) experienced more than one episode of peritonitis, 138 patients (21.1%) underwent technique failure, and 78 patients (11.9%) died. After adjustment, middle school or lower education group was an independent risk factor for peritonitis (adjusted hazard ratio [HR], 1.61; 95% confidence interval [CI], 1.10-2.36; P = 0.015) and technique failure (adjusted HR, 1.87; 95% CI, 1.10-3.18; P = 0.038), compared with higher than high school education group. However, lower education was not associated with increased mortality either by as-treated (adjusted HR, 1.11; 95% CI, 0.53-2.33; P = 0.788) or intent-to-treat analysis (P = 0.726). Although lower education was a significant risk factor for peritonitis and technique failure, it was not associated with increased mortality in PD patients. Comprehensive training and multidisciplinary education may overcome the lower education level in PD.

We evaluated the incidence and risk factors of resistant Escherichia coli infections after the prostate biopsy under flouroquinolone prophylaxis. From January 2003 to December 2012, we retrospectively evaluated the records of 2215 patients. The risk factors were described for infective complications and resistant E. coli in positive cultures was calculated. Of 2215 patients, 153 had positive urine cultures, such as 129 (84·3%) E. coli, 8 (5·2%) Enterococcus spp., 6 (3·9%) Enterobacter spp., 5 (3·2%) Pseudomonas spp., 3 (1·9%) MRCNS, and 2 (1·3%) Klebsiella spp. Of the positive urine cultures which yielded E. coli, 99 (76·7%) were evaluated for fluoroquinolone resistance. Of those, 83 (83·8%) were fluoroquinolone-resistant and composed of 51 (61·4%) extended-spectrum beta-lactamase (ESBL)-positive. Fluoroquinolone-resistant E. coli ratios were 73·4 and 95·9% before 2008 and after 2008, respectively (P = 0·002). The most sensitive antibiotics for fluoroquinolone-resistant E. coli strains were imipenem (100%), amikacin (84%) and cefoperazone (83%). The use of quinolones in the last 6 months and a history of hospitalization in the last 30 days were found to be significant risk factors. We found that resistant E. coli strains might be a common microorganism in patients with this kind of complication. The risk factors for development of infection with these resistant strains were history of the use of fluoroquinolones and hospitalization.
Full Text Available Background: Breast cancer is the most common malignancy among women worldwide. In Iran, breast cancer ranks first among cancers diagnosed in women. Nevertheless, many of women haven’t enough knowledge about breast cancer risk factors and symptoms. The main reason for this escalating mortality is lack of awareness and late diagnosis of disease. The aim of present study assessed the knowledge about risk factors and symptoms of breast cancer, also the screening method and practice (Breast self examination about it. Methods: This is a descriptive and cross-sectional study. In this study 340 red crescent volunteer women participated in a national congress were selected with convenience sampling method. The data collection instrument consisted of a three part questionnaire which included demographic factors, Knowledge level about risk factors, symptoms and screening methods of breast cancer and questions concerning practice about breast self examination (BSE.The study tool was a researcher-designed questionnaire which could evaluated a number of variables. After data collection, analysis was carried out with descriptive tests by SPSS.16 software. Results: The mean age of subjects was 23±2.1yrs. Knowledge about breast cancer risk factors was very poor, the most widely known risk factor and lowest among the participants was family history of breast cancer (30.6 % and early menarche (under 12 years (0.3% respectively. Only 47.9% respondents correctly recognized breast lump and 11.2% breast discharge as the most common symptoms of breast cancer.30% of subjects were aware of BSE. However, a lesser proportion (9.4% was done BSE regular monthly every few months. Conclusion: Regarding the low level of the women’s knowledge about breast cancer especially in young educated women, screening and interventional programs to improve awareness and practice is essential.

In France, consumption of gambling games increased by 148% between 1960 and 2005. In 2004, gamblers lost approximately 0.9% of household income, compared to 0.4% in 1960. This represents approximately 134 Euros per year and per head. In spite of this important increase, the level remains lower than the European average (1%). However, gambling practices may continue to escalate in France in the next few years, particularly with the recent announce of the legalisation of online games and sports betting. With the spread of legalised gambling, pathological gambling rates may increase in France in the next years, in response to more widely available and more attractive gambling opportunities. In this context, there is a need for better understanding of the risk factors that are implicated in the development and maintenance of pathological gambling. This paper briefly describes the major risk factors for pathological gambling by examining the recent published literature available during the first quarter of 2008. This documentary basis was collected by Inserm for the collective expert report procedure on Gambling (contexts and addictions). Seventy-two articles focusing on risk factors for pathological gambling were considered in this review. Only 47 of them were taken into account for analysis. The selection of these 47 publications was based on the guide on literature analysis established by the French National Agency for Accreditation and Assessment in Health (ANAES, 2000). Some publications from more recent literature have also been added, mostly about Internet gambling. We identify three major types of risk factors implicated in gambling problems: some of them are related to the subject (individual factors), others are related to the object of the addiction, here the gambling activity by itself (structural factors), and the last are related to environment (contextual or situational factors). Thus, the development and maintenance of pathological gambling seems to be

Full Text Available Abstract Background Diarrhoea and acute respiratory conditions are common medical conditions among under-five children in resource-limited and conflict situations. The present study was conducted to estimate the prevalence and associated factors for acute respiratory conditions and diarrhoea among children under the age of five years in Iraq in 2000. Methods Data for the Iraqi Multiple Indicator Cluster Survey were obtained from UNICEF. We estimated the prevalence of acute respiratory conditions and diarrhoea. Assessment of the associations between these two medical conditions on one hand and socio-demographic and environmental variables on the other was done using logistic regression analysis. Weighted analysis was conducted to account for complex survey design. Results A total of 14,676 children under the age of 5 years were reported by their mothers in the study. Of these 50.4% were males. About half (53.9% of the children had complete vaccination status. Overall, 21.3% of the children had diarrhoea, and 6.9% had acute respiratory infection (ARI in the last two weeks. In multivariate analysis, diarrhoea was associated with age of child, area of residence, maternal education, source of water, toilet facility, disposal of children' stool and disposal of dirty water. Compared to children aged 48–59 months, children in the age groups 6–11 months and 12–23 months were 2.22 (95%CI [2.02, 2.44] and 1.84 (95%CI [1.71, 2.00] times more likely, respectively, to have diarrhoea. Children whose mothers had no formal education were 11% (AOR = 1.11, 95%CI [1.04, 1.18] more likely to have diarrhoea compared to children with mothers who had attained secondary level of education. Compared to children who belonged to households with unprotected well or river as the main source of water, children who belonged to households with piped water were 32% (AOR = 1.32, 95%CI [1.17, 1.48] more likely to have diarrhoea while those who belonged to households with

Ethiopia has made remarkable progress in reducing child mortality over the last two decades. However, the under-5 mortality rate in Ethiopia is still higher than the under-5 mortality rates of several low- and middle-income countries (LMIC). On the other hand, the patterns and causes of child mortality have not been well investigated in Ethiopia. The objective of this study was to investigate the mortality trend, causes of death, and risk factors among children under 5 in Ethiopia during 1990-2013. We used Global Burden of Disease (GBD) 2013 data. Spatiotemporal Gaussian Process Regression (GPR) was applied to generate best estimates of child mortality with 95% uncertainty intervals (UI). Causes of death by age groups, sex, and year were measured using Cause of Death Ensemble modeling (CODEm). For estimation of HIV/AIDS mortality rate, the modified UNAIDS EPP-SPECTRUM suite model was used. Between 1990 and 2013 the under-5 mortality rate declined from 203.9 deaths/1000 live births to 74.4 deaths/1000 live births with an annual rate of change of 4.6%, yielding a total reduction of 64%. Similarly, child (1-4 years), post-neonatal, and neonatal mortality rates declined by 75%, 64%, and 52%, respectively, between 1990 and 2013. Lower respiratory tract infection (LRI), diarrheal diseases, and neonatal syndromes (preterm birth complications, neonatal encephalopathy, neonatal sepsis, and other neonatal disorders) accounted for 54% of the total under-5 deaths in 2013. Under-5 mortality rates due to measles, diarrhea, malaria, protein-energy malnutrition, and iron-deficiency anemia declined by more than two-thirds between 1990 and 2013. Among the causes of under-5 deaths, neonatal syndromes such as sepsis, preterm birth complications, and birth asphyxia ranked third to fifth in 2013. Of all risk-attributable deaths in 1990, 25% of the total under-5 deaths (112,288/435,962) and 48% (112,288/232,199) of the deaths due to diarrhea, LRI, and other common infections were

Under-five mortality is declining in Ghana and many other countries. Very few studies have measured under-five mortality-and its social and environmental risk factors-at fine spatial resolutions, which is relevant for policy purposes. Our aim was to estimate under-five mortality and its social and environmental risk factors at the district level in Ghana. We used 10% random samples of Ghana's 2000 and 2010 National Population and Housing Censuses. We applied indirect demographic methods and a Bayesian spatial model to the information on total number of children ever born and children surviving to estimate under-five mortality (probability of dying by 5 y of age, 5q0) for each of Ghana's 110 districts. We also used the census data to estimate the distributions of households or persons in each district in terms of fuel used for cooking, sanitation facility, drinking water source, and parental education. Median district 5q0 declined from 99 deaths per 1,000 live births in 2000 to 70 in 2010. The decline ranged from 40% in southern districts, where it had been lower in 2000, exacerbating existing inequalities. Primary education increased in men and women, and more households had access to improved water and sanitation and cleaner cooking fuels. Higher use of liquefied petroleum gas for cooking was associated with lower 5q0 in multivariate analysis. Under-five mortality has declined in all of Ghana's districts, but the cross-district inequality in mortality has increased. There is a need for additional data, including on healthcare, and additional environmental and socioeconomic measurements, to understand the reasons for the variations in mortality levels and trends.

Children with diarrhea hospitalized for respiratory distress often have fatal outcome in resource-limited settings, although data are lacking on risk factors for death in such children. We sought to evaluate clinical predictors for death in such children. In this prospective cohort study, we enrolled under-5 children with diarrhea admitted with severe respiratory distress to the intensive care unit of Dhaka Hospital of International Centre for Diarhoeal Disease Research, Bangladesh, from September 2014 through September 2015. We compared clinical and laboratory characteristics between study children those who died (n = 29) and those who survived (n = 62). In logistic regression analysis, after adjusting for potential confounders, the independent predictors for death in children hospitalized for diarrhea and severe respiratory distress were severe sepsis and hypoglycemia ( P < .05 for all). Thus, recognition of these simple parameters may help clinicians identify children with diarrhea at risk of deaths in order to initiate prompt management for the better outcome, especially in resource-poor settings.
It is no longer reasonable to divide cancers into those that are genetic in origin and those that are environmental in origin. With rare exception, carcinogenesis involves environmental factors that directly or indirectly exert a change in the cell's genome. Virtually all causes of cancer are multifactorial, sometimes involving an inherited predisposition to the carcinogenic effects of environmental factors, which include chemicals, ionizing radiation, and oncogenic virus. Carcinogenesis is a multistep process including induction, promotion, and progression. Initiation requires an irreversible change in the cellular genome, whereas promotion is commonly associated with prolonged and reversible exposure. Tumor progression results in genotypic and phenotypic changes associated with tumor growth, invasion, and metastasis. Most information on human cancer risk is based on epidemiologic studies involving both exposed and unexposed individuals. The quality of such studies depends on their ability to assess the strength of any association of exposure and disease and careful attention to any potential bias. Few cancers are inherited in a Mendelian fashion. Several preneoplastic conditions, however, are clearly inherited and several malignancies demonstrate weak familial patterns. Environmental factors may exert their effect on DNA in a random fashion, but certain consistent changes, including specific translocations of genetic information, are often found. Currently, there is great interest in the close proximity of certain oncogenes governing growth control to the consistent chromosomal changes observed. Such changes may represent a final common pathway of action for environmental carcinogens. Sufficient laboratory and epidemiologic evidence exists to establish a causal association of several chemical agents with cancer

A prospective weekly home surveillance study was undertaken to determine morbidity patterns within the Butajira Rural Health project in central Ethiopia. Overall prevalence of illness was 5.8% in 1216 person-years observed among rural Ethiopian children aged under 5 years. Acute respiratory infections (ARI) (prevalence 2.8%) and acute diarrhoea (2.4%) were the commonest conditions. Episodes of illness were distributed unequally among children, with a mean of 2.34 episodes per child. These included an average of 1.13 episodes of ARI (of which 0.16 had lower respiratory symptoms [ALRI]) and 1.17 episodes of acute diarrhoea. Sanitation factors were the principal risks for gastroenteritis, while living in rural areas predisposed children to ARI. Parental factors such as illiteracy were also linked to morbidity.
The Risk Factor Assessment Branch (RFAB) focuses on the development, evaluation, and dissemination of high-quality risk factor metrics, methods, tools, technologies, and resources for use across the cancer research continuum, and the assessment of cancer-related risk factors in the population.

Full Text Available Background and Design: There have been reports suggesting the involvement of environmental factors in the disease process of pemphigus. In this study, we aimed to find out the risk factors which could play role in the etiopathogenesis in our pemphigus patients.Material and method: A total of 42 patients (15 male and 27 female who were diagnosed as pemphigus with histopathological and direct immunoflurosence examinations in our clinic between the years 1998-2004, were interviewed for assessment of regarding with the subjects of the demographic properties, occupational groups, educational level, the number of pregnancies, stressfull life events, diet habits, smoking and alcohol consumption before the onset of the disease and the results were compared to 42 age and gender-matched controls with similar socioeconomic circumstances. Results: Working in agriculture and livestock, multi-parity, absence of smoking and stressfull life events were found to be statistically significant in pemphigus patients than in controls. Conclusion: Working in agriculture and livestock, multi-parity, absence of smoking and stressfull life events were assumed to play role in the etiopathogenesis and course of pemphigus.

Impaired gait may contribute to the increased rate of falls in cognitively impaired older people. We investigated whether gait under simple and dual task conditions could predict falls in this group. The study sample consisted of 64 community dwelling older people with mild to moderate cognitive impairment. Participants walked at their preferred speed under three conditions: (a) simple walking, (b) walking while carrying a glass of water and (c) walking while counting backwards from 30. Spatiotemporal gait parameters were measured using the GAITRite(®) mat. Falls were recorded prospectively for 12months with the assistance of carers. Twenty-two (35%) people fell two or more times in the 12month follow-up period. There was a significant main effect of gait condition and a significant main effect of faller status for mean value measures (velocity, stride length, double support time and stride width) and for variability measures (swing time variability and stride length variability). Examination of individual gait parameters indicated that the multiple fallers walked more slowly, had shorter stride length, spent longer time in double support, had a wider support width and showed more variability in stride length and swing time (p<0.05). There was no significant interaction between gait condition and faller status for any of the gait variables. In conclusion, dual task activities adversely affect gait in cognitively impaired older people. Multiple fallers performed worse in each gait condition but the addition of a functional or cognitive secondary task provided no added benefit in discriminating fallers from non-fallers with cognitive impairment.

Purpose: To investigate the psychological consequences of high-dose-rate brachytherapy with 2 fractions in 1 application under spinal/epidural anesthesia in the treatment of locally advanced cervical cancer. Methods and Materials: In 50 patients with locally advanced cervical cancer, validated questionnaires were used for prospective assessment of acute and posttraumatic stress disorder (ASD/PTSD) (Impact of Event Scale–Revision), anxiety/depression (Hospital Anxiety and Depression Scale), quality of life (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30/Cervical Cancer 24), physical functioning (World Health Organization performance status), and pain (visual analogue scale), before and during treatment and 1 week and 3 months after treatment. Qualitative interviews were recorded in open format for content analysis. Results: Symptoms of ASD occurred in 30% of patients 1 week after treatment; and of PTSD in 41% 3 months after treatment in association with this specific brachytherapy procedure. Pretreatment predictive variables explain 82% of the variance of PTSD symptoms. Helpful experiences were the support of the treatment team, psychological support, and a positive attitude. Stressful factors were pain, organizational problems during treatment, and immobility between brachytherapy fractions. Conclusions: The specific brachytherapy procedure, as performed in the investigated mono-institutional setting with 2 fractions in 1 application under spinal/epidural anesthesia, bears a considerable risk of traumatization. The source of stress seems to be not the brachytherapy application itself but the maintenance of the applicator under epidural anesthesia in the time between fractions. Patients at risk may be identified before treatment, to offer targeted psycho-social support. The patients' open reports regarding helpful experiences are an encouraging feedback for the treatment team; the reported stressful

Cannabis users are more likely to have psychotic experiences (PEs). The degree to which these associations are driven by genetic or environmental influences in adolescence is unknown. This study estimated the genetic and environmental contributions to the relationship between cannabis use and PEs. Specific PEs were measured in a community-based twin sample (4830 16-year-old pairs) using self-reports and parent-reports. Adolescents reported on ever using cannabis. Multivariate liability threshold structural equation model-fitting was conducted. Cannabis use was significantly correlated with PEs. Modest heritability (37%), common environmental influences (55%) and unique environment (8%) were found for cannabis use. For PEs, modest heritability (27–54%), unique environmental influences (E=12–50%) and little common environmental influences (11–20%), with the exception of parent-rated Negative Symptoms (42%), were reported. Environmental influences explained all of the covariation between cannabis use and paranoia, cognitive disorganization and parent-rated negative symptoms (bivariate common environment=69–100%, bivariate unique environment=28–31%), whilst the relationship between cannabis use and hallucinations indicated familial influences. Cannabis use explains 2–5% of variance in positive, cognitive, and negative PEs. Cannabis use and psychotic experience co-occur due to environmental factors. Focus on specific environments may reveal why adolescent cannabis use and psychotic experiences tend to ‘travel together’. PMID:25912376

Nine incidents of multiple-victim homicide in American secondary schools are examined and common risk factors are identified. The literature dealing with individual, family, social, societal, and situational risk factors for youth violence and aggression is reviewed along with existing risk assessment methods. Checklists of risk factors for serious youth violence and school violence are used in reviewing each school shooting case. Commonalties among the cases and implications for psychologists practicing in clinical and school settings are discussed.
Full Text Available Abstract Background Ethiopia has made remarkable progress in reducing child mortality over the last two decades. However, the under-5 mortality rate in Ethiopia is still higher than the under-5 mortality rates of several low- and middle-income countries (LMIC. On the other hand, the patterns and causes of child mortality have not been well investigated in Ethiopia. The objective of this study was to investigate the mortality trend, causes of death, and risk factors among children under 5 in Ethiopia during 1990–2013. Methods We used Global Burden of Disease (GBD 2013 data. Spatiotemporal Gaussian Process Regression (GPR was applied to generate best estimates of child mortality with 95% uncertainty intervals (UI. Causes of death by age groups, sex, and year were measured using Cause of Death Ensemble modeling (CODEm. For estimation of HIV/AIDS mortality rate, the modified UNAIDS EPP-SPECTRUM suite model was used. Results Between 1990 and 2013 the under-5 mortality rate declined from 203.9 deaths/1000 live births to 74.4 deaths/1000 live births with an annual rate of change of 4.6%, yielding a total reduction of 64%. Similarly, child (1–4 years, post-neonatal, and neonatal mortality rates declined by 75%, 64%, and 52%, respectively, between 1990 and 2013. Lower respiratory tract infection (LRI, diarrheal diseases, and neonatal syndromes (preterm birth complications, neonatal encephalopathy, neonatal sepsis, and other neonatal disorders accounted for 54% of the total under-5 deaths in 2013. Under-5 mortality rates due to measles, diarrhea, malaria, protein-energy malnutrition, and iron-deficiency anemia declined by more than two-thirds between 1990 and 2013. Among the causes of under-5 deaths, neonatal syndromes such as sepsis, preterm birth complications, and birth asphyxia ranked third to fifth in 2013. Of all risk-attributable deaths in 1990, 25% of the total under-5 deaths (112,288/435,962 and 48% (112,288/232,199 of the deaths due to

Studied theoretical and methodological aspects of the risk classification of factoring operations in the part of the risk assessment factors. It is proposed to consider the risks factors as the risk that is acceptable controlled by accounting instruments and the risks that can not be taken into account in the accounting records. To minimize the risk factor, accounting-driven tools, a method of self-insurance, which is a factor in the creation of provision for factoring transactions designed to cover unexpected expenses and losses. Provision for factoring factor will establish more stable conditions of financial activity and avoid the fluctuations of profit factor in relation to the writing off of losses on factoring operatsіyam.Developed proposals allow for further research to improve the organizational and methodological basis of accounting and analysis of information as a basis for providing risk management factor, particularly in terms of improving the evaluation questions such risks and their qualitative and quantitative analysis.

Abstract One of the most important adverse effects of zoledronic acid (ZA) is osteonecrosis of the jaw (ONJ). In previous literature, several risk factors have been identified in the development of ONJ. In this study, we aimed to determine the role of trastuzumab, an antiangiogenic agent, as an independent risk factor for the development of this serious side effect. Our study included 97 patients (mean age: 54 ± 10 years) with breast cancer, recorded in the archives of the Istanbul Florence Nightingale Breast Study Group, who received ZA therapy due to bone metastases between March 2006 and December 2013. We recorded the patients’ ages, weights, duration of treatment with ZA, number of ZA infusions, dental procedures, anticancer treatments (chemotherapy, aromatase inhibitor, trastuzumab), the presence of diabetes mellitus or renal dysfunction, and smoking habits. Thirteen patients (13.40%) had developed ONJ. Among the patients with ONJ, the mean time of exposure to ZA was 41 months (range: 13–82) and the mean number of ZA infusions was 38 (range: 15–56). The duration of treatment with ZA and the use of trastuzumab were observed to be 2 factors that influenced the development of ONJ (P = 0.049 and P = 0.028, respectively). The development of ONJ under ZA treatment may be associated solely with the duration of ZA treatment and the concurrent administration of trastuzumab. These findings show that patients who are administered trastuzumab for metastatic breast cancer while undergoing ZA treatment are prone to developing ONJ. Therefore, we recommend intense clinical observation to avoid this particular condition in patients receiving ZA and trastuzumab. PMID:25950681

Ninety-one Swiss veal farms producing under a label with improved welfare standards were visited between August and December 2014 to investigate risk factors related to antimicrobial drug use and mortality. All herds consisted of own and purchased calves, with a median of 77.4% of purchased calves. The calves' mean age was 29±15days at purchasing and the fattening period lasted at average 120±28 days. The mean carcass weight was 125±12kg. A mean of 58±33 calves were fattened per farm and year, and purchased calves were bought from a mean of 20±17 farms of origin. Antimicrobial drug treatment incidence was calculated with the defined daily dose methodology. The mean treatment incidence (TIADD) was 21±15 daily doses per calf and year. The mean mortality risk was 4.1%, calves died at a mean age of 94±50 days, and the main causes of death were bovine respiratory disease (BRD, 50%) and gastro-intestinal disease (33%). Two multivariable models were constructed, for antimicrobial drug treatment incidence (53 farms) and mortality (91 farms). No quarantine, shared air space for several groups of calves, and no clinical examination upon arrival at the farm were associated with increased antimicrobial treatment incidence. Maximum group size and weight differences >100kg within a group were associated with increased mortality risk, while vaccination and beef breed were associated with decreased mortality risk. The majority of antimicrobial treatments (84.6%) were given as group treatments with oral powder fed through an automatic milk feeding system. Combination products containing chlortetracycline with tylosin and sulfadimidine or with spiramycin were used for 54.9%, and amoxicillin for 43.7% of the oral group treatments. The main indication for individual treatment was BRD (73%). The mean age at the time of treatment was 51 days, corresponding to an estimated weight of 80-100kg. Individual treatments were mainly applied through injections (88.5%), and included

Full Text Available Children with diarrhea hospitalized for respiratory distress often have fatal outcome in resource-limited settings, although data are lacking on risk factors for death in such children. We sought to evaluate clinical predictors for death in such children. In this prospective cohort study, we enrolled under-5 children with diarrhea admitted with severe respiratory distress to the intensive care unit of Dhaka Hospital of International Centre for Diarhoeal Disease Research, Bangladesh, from September 2014 through September 2015. We compared clinical and laboratory characteristics between study children those who died (n = 29 and those who survived (n = 62. In logistic regression analysis, after adjusting for potential confounders, the independent predictors for death in children hospitalized for diarrhea and severe respiratory distress were severe sepsis and hypoglycemia (P < .05 for all. Thus, recognition of these simple parameters may help clinicians identify children with diarrhea at risk of deaths in order to initiate prompt management for the better outcome, especially in resource-poor settings.

Preventing stress fractures requires knowledge of the risk factors that predispose to this injury. The aetiology of stress fractures is multifactorial, but methodological limitations and expediency often lead to research study designs that evaluate individual risk factors. Intrinsic risk factors include mechanical factors such as bone density, skeletal alignment and body size and composition, physiological factors such as bone turnover rate, flexibility, and muscular strength and endurance, as well as hormonal and nutritional factors. Extrinsic risk factors include mechanical factors such as surface, footwear and external loading as well as physical training parameters. Psychological traits may also play a role in increasing stress fracture risk. Equally important to these types of analyses of individual risk factors is the integration of information to produce a composite picture of risk. The purpose of this paper is to critically appraise the existing literature by evaluating study design and quality, in order to provide a current synopsis of the known scientific information related to stress fracture risk factors. The literature is not fully complete with well conducted studies on this topic, but a great deal of information has accumulated over the past 20 years. Although stress fractures result from repeated loading, the exact contribution of training factors (volume, intensity, surface) has not been clearly established. From what we do know, menstrual disturbances, caloric restriction, lower bone density, muscle weakness and leg length differences are risk factors for stress fracture. Other time-honoured risk factors such as lower extremity alignment have not been shown to be causative even though anecdotal evidence indicates they are likely to play an important role in stress fracture pathogenesis.

Full Text Available Allostatic load is a commonly used metric of health risk based on the hypothesis that recurrent exposure to environmental demands (e.g., stress engenders a progressive dysregulation of multiple physiological systems. Prominent indicators of response to environmental challenges, such as stress-related hormones, sympatho-vagal balance, or inflammatory cytokines, comprise primary allostatic mediators. Secondary mediators reflect ensuing biological alterations that accumulate over time and confer risk for clinical disease but overlap substantially with a second metric of health risk, the metabolic syndrome. Whether allostatic load mediators covary and thus warrant treatment as a unitary construct remains to be established and, in particular, the relation of allostatic load parameters to the metabolic syndrome requires elucidation. Here, we employ confirmatory factor analysis to test: 1 whether a single common factor underlies variation in physiological systems associated with allostatic load; and 2 whether allostatic load parameters continue to load on a single common factor if a second factor representing the metabolic syndrome is also modeled. Participants were 645 adults from Allegheny County, PA (30-54 years old, 82% non-Hispanic white, 52% female who were free of confounding medications. Model fitting supported a single, second-order factor underlying variance in the allostatic load components available in this study (metabolic, inflammatory and vagal measures. Further, this common factor reflecting covariation among allostatic load components persisted when a latent factor representing metabolic syndrome facets was conjointly modeled. Overall, this study provides novel evidence that the modeled allostatic load components do share common variance as hypothesized. Moreover, the common variance suggests the existence of statistical coherence above and beyond that attributable to the metabolic syndrome.

Human decision making under risk and uncertainty may depend on individual involvement in the outcome-generating process. Expected utility theory is silent on this issue. Prospect theory in its current form offers little, if any, prediction of how or why involvement in a process should matter, although it may offer ex post interpretations of empirical findings. Well-known findings in psychology demonstrate that when subjects exercise more involvement or choice in lottery procedures, they value their lottery tickets more highly. This often is interpreted as an "illusion of control," meaning that when subjects are more involved in a lottery, they may believe they are more likely to win, perhaps because they perceive that they have more control over the outcome. Our experimental design eliminates several possible alternative explanations for the results of previous studies in an experiment that varies the degree and type of involvement in lottery procedures. We find that in treatments with more involvement subjects on average place less rather than more value on their lottery tickets. One possible explanation for this is that involvement interacts with loss aversion by causing subjects to weigh losses more heavily than they would otherwise. One implication of our study is that involvement, either independently or in interaction with myopic loss aversion, may help explain the extreme risk aversion of bond investors.

Dementias, such as Alzheimer's disease (AD) and vascular dementia, are disorders of aging populations and represent a significant economic burden. Evidence is accumulating to suggest that cardiovascular disease (CVD) risk factors may be instrumental in the development of dementia. The goal of this review was to discuss the relationship between specific CVD risk factors and dementia and how current treatment strategies for dementia should focus on reducing CVD risks. We conducted a review of the literature for the simultaneous presence of 2 major topics, cardiovascular risk factors and dementia (eg, AD). Special emphasis was placed on clinical outcome studies examining the effects of treatments of pharmacologically modifiable CVD risk factors on dementia and cognitive impairment. Lifestyle risk factors for CVD, such as obesity, lack of exercise, smoking, and certain psychosocial factors, have been associated with an increased risk of cognitive decline and dementia. Some evidence suggests that effectively managing these factors may prevent cognitive decline/dementia. Randomized, placebo-controlled trials of antihypertensive medications have found that such therapy may reduce the risk of cognitive decline, and limited data suggest a benefit for patients with AD. Some small open-label and randomized clinical trials of statins have observed positive effects on cognitive function; larger studies of statins in patients with AD are ongoing. Although more research is needed, current evidence indicates an association between CVD risk factors--such as hypertension, dyslipidemia, and diabetes mellitus--and cognitive decline/dementia. From a clinical perspective, these data further support the rationale for physicians to provide effective management of CVD risk factors and for patients to be compliant with such recommendations to possibly prevent cognitive decline/dementia.

In low and middle-income countries, acute lower respiratory illness is responsible for roughly 1 in every 5 child deaths. Rwanda has made major health system improvements including its community health worker systems, and it is one of the few countries in Africa to meet the 2015 Millennium Development Goals, although prevalence of acute lower respiratory infections (4 %) is similar to other countries in sub-Saharan Africa. This study aims to assess social, economic, and environmental factors associated with acute lower respiratory infections among children under five to inform potential further improvements in the health system. This is a cross-sectional study using data collected from women interviewed in the 2010 DHS about 8,484 surviving children under five. Based on a literature review, we defined 19 health, social, economic, and environmental potential risk factors, tested bivariate associations with acute lower respiratory infections, and advanced variables significant at the 0.1 confidence level to logistic regression modelling. We used manual backward stepwise regression to arrive at a final model. All analyses were performed in Stata v13 and adjusted for complex sample design. The following factors were independently associated with acute lower respiratory infections: child's age, anemia level, and receipt of Vitamin A; household toilet type and residence, and season of interview. In multivariate regression, being in the bottom ten percent of households (OR: 1.27, 95 % CI: 0.85-1.87) or being interviewed during the rainy season (OR: 1.61, 95 % CI: 1.24-2.09) was positively associated with acute lower respiratory infections, while urban residence (OR: 0.58, 95 % CI: 0.38-0.88) and being age 24-59 months versus 0-11 months (OR: 0.53, 95 % CI: 0.40-0.69) was negatively associated with acute lower respiratory infections. Potential areas for intervention including community campaigns about acute lower respiratory infections symptoms and treatment, and

In brief: Many children and adolescents participate in sports that put them at risk for musculoskeletal injuries. Underlying physical conditions, or risk factors, may predispose them to particular types of sports injuries. Research shows that these risk factors fall into five categories: body type, flexibility, muscle strength, inadequate rehabilitation of a previous injury, and skeletal malalignment and anomalies. Some findings show, for example, that youthful football players who are also heavy have an increased rate of injury, sprains and strains are less common in flexible athletes, and patellar pain or subluxation may be related to a variety of malalignment factors. The authors recommend using a systematic, integrated approach to risk assessment of the athlete, both for detecting risk factors and determining their potential for con tribu ting to a sports injury.

Full Text Available Respiratory syncytial virus (RSV is the most common pathogen identified in young children with acute lower respiratory infection (ALRI as well as an important cause of hospital admission. The high incidence of RSV infection and its potential severe outcome make it important to identify and prioritise children who are at higher risk of developing RSV–associated ALRI. We aimed to identify risk factors for RSV–associated ALRI in young children. We carried out a systematic literature review across 4 databases and obtained unpublished studies from RSV Global Epidemiology Network (RSV GEN collaborators. Quality of all eligible studies was assessed according to modified GRADE criteria. We conducted meta–analyses to estimate odds ratios with 95% confidence intervals (CI for individual risk factors. We identified 20 studies (3 were unpublished data with “good quality” that investigated 18 risk factors for RSV–associated ALRI in children younger than five years old. Among them, 8 risk factors were significantly associated with RSV–associated ALRI. The meta–estimates of their odds ratio (ORs with corresponding 95% confidence intervals (CI are prematurity 1.96 (95% CI 1.44–2.67, low birth weight 1.91 (95% CI 1.45–2.53, being male 1.23 (95% CI 1.13–1.33, having siblings 1.60 (95% CI 1.32–1.95, maternal smoking 1.36 (95% CI 1.24–1.50, history of atopy 1.47 (95% CI 1.16–1.87, no breastfeeding 2.24 (95% CI 1.56–3.20 and crowding 1.94 (95% CI 1.29–2.93. Although there were insufficient studies available to generate a meta–estimate for HIV, all articles (irrespective of quality scores reported significant associations between HIV and RSV–associated ALRI. This study presents a comprehensive report of the strength of association between various socio–demographic risk factors and RSV–associated ALRI in young children. Some of these amenable risk factors are similar to those that have been identified for (all cause ALRI and

A survey was conducted to estimate the prevalence of Anaplasma, Babesia and Brucella spp. infections in cattle, goats and sheep in the Karamoja Region of Uganda and to identify possible risk factors existing in this semi-nomadic and pastoral area. Low cost laboratory tests were used to diagnose infections (Rose Bengal test for Brucella spp. antibodies and direct microscopic examination for Anaplasma and Babesia spp.). Multivariable logistic regression models were applied to identify possible risk factors linked to gender, animal species, age (only for cattle) and districts. A total of 3935 cattle, 729 goats and 306 sheep of five districts of the Karamoja Region were tested. Seroprevalence for Brucella was 9.2 % (CI, 95 %: 8.4-10), for Anaplasma 19.5 % (CI 95 %: 18.4-20.6) and for Babesia 16 % (CI 95 %: 15-17.1). Significant differences in infections prevalence were observed against risk factors associated with districts and species. Cattle were the species with higher risk of the infections. Female gender was identified as at risk only for Brucella spp. infection. Cattle more than one year old had greater likelihood to be Brucella seropositive. Co-infections of Anaplasma and Babesia spp. were statistically associated, especially in goats and sheep. Further studies to identify risk factors related to host species and geographical districts are needed. The influence on the semi-nomadic agro-pastoral system in Karamoja of animal raids and animal mixing should be further investigated. Findings were important to sensitize Karamojong undertaking measures on infection control, especially on cattle, which are their main source of food.

Soccer is the most commonly played sport in the world, with an estimated 265 million active soccer players by 2006. Inherent to this sport is the higher risk of injury to the anterior cruciate ligament (ACL) relative to other sports. ACL injury causes the most time lost from competition in soccer which has influenced a strong research focus to determine the risk factors for injury. This research emphasis has afforded a rapid influx of literature defining potential modifiable and non-modifiable risk factors that increase the risk of injury. The purpose of the current review is to sequence the most recent literature that reports potential mechanisms and risk factors for non-contact ACL injury in soccer players. Most ACL tears in soccer players are non-contact in nature. Common playing situations precluding a non-contact ACL injury include: change of direction or cutting maneuvers combined with deceleration, landing from a jump in or near full extension, and pivoting with knee near full extension and a planted foot. The most common non-contact ACL injury mechanism include a deceleration task with high knee internal extension torque (with or without perturbation) combined with dynamic valgus rotation with the body weight shifted over the injured leg and the plantar surface of the foot fixed flat on the playing surface. Potential extrinsic non-contact ACL injury risk factors include: dry weather and surface, and artificial surface instead of natural grass. Commonly purported intrinsic risk factors include: generalized and specific knee joint laxity, small and narrow intercondylar notch width (ratio of notch width to the diameter and cross sectional area of the ACL), pre-ovulatory phase of menstrual cycle in females not using oral contraceptives, decreased relative (to quadriceps) hamstring strength and recruitment, muscular fatigue by altering neuromuscular control, decreased "core" strength and proprioception, low trunk, hip, and knee flexion angles, and high

The purpose of the present study is to compare risk factors of necrotizing enterocolitis (NEC) between two group: group A, newborns with the disease and group B, newborns with other diseases different from NEC, in order to know if these risk factors are more frequent or not in the first group. We assessed the clinical records of all the patients hospitalized in the Neonatal Intensive Care Unit and Neonatology Service of the La Raza General Hospital between 1987 and 1991 with the diagnosis of NEC. They were compared with 65 clinical records chosen at random of patients hospitalized in the same Unit with other diagnosis at the same time, and who were discharged by improvement or deceased. In all of them were look for known risk factors for NEC generally accepted such as: prematurity, neonatal asphyxia, poliglobulia, cyanotic congenital heart disease, patent ductus arteriosus, respiratory distress syndrome, catheterization of umbilical vessels, early feeding of elevated formula increases, exchange exchange transfusion, hypoxic ischemic encephalopathy, infection, etc. Just 25 records of the possible 50 with the diagnosis of NEC full filled inclusion criteria. There were no statistically significant difference in weight, sex, mortality and known risk factors of NEC between both groups. Were concluded that NEC is a disease of unknown etiology that should be studied more thoroughly. The known risk factors must be avoided because the patient susceptibility probably play an important role.
Full Text Available Febrile seizures are the most frequent neurological disorder in the childhood. According to American Academy of Pediatrics (AAP, they have been defined as seizures provoked by high temperature in children aged between 6 months and 5 years, without previous history of afebrile seizures, intracranial infections and other possible causes of seizures. Seizures can be typical and atypical, according to the characteristics. Pathogenesis of this disorder has not been clarified yet, and it is believed to be a combination of genetic factors, high body temperature and brain maturation. The risk factors for recurrence of febrile seizures are: age in which seizures appeared for the first time, epilepsy in the first degree relative, febrile seizures in the first degree relative, frequent diseases with fever and low body temperature on the beginning of seizures. The frequency of recurrent seizures The risk for occurrence of epilepsy in children with simple seizures is about 1-1.5%, which is slightly higher compared to general population, while it increases to 4-15% in patients with complex seizures. However, there is no evidence that therapy prevents occurrence of epilepsy. When the prevention of recurrent seizures is considered, it is necessary to separate simple from complex seizures. The aim of this paper was to analyze the most important risk factors for febrile seizures, and to evaluate their impact on occurrence of recurrent seizures. Our study included 125 children with febrile seizures, aged from 6 months to 5 years. The presence of febrile seizures and epilepsy in the first degree relative has been noted in 22% of children. Typical febrile seizures were observed in 76% of cases, and atypical in 24%. Most patients had only one seizure (73.6%. Children, who had seizure earlier in life, had more frequent recurrences. Both risk factors were present in 25% of patients, while 68% of patients had only one risk factor. For the children with febrile disease
For the purposes of radiation protection, the noteworthy risk of thyroid is carcinogenesis. The risk factor which ICRP presented in the publication-26 is 5 x 10 - 6 rem - 1 . This numerical value is based upon the estimated likelihood of inducing fatal thyroid cancer. On the other hand, the risk factor presented by the BEIR report is 4 x 10 - 6 yr - 1 . This value was decided after consideration of the risks of both fatal and non-fatal cancer of thyroid. The following features distinguished thyroid cancer from malignancy of other tissue from medical point of view. 1) A large difference between incidence and mortality in case of thyroid cancer is recognized, because the thyroid cancer could be successfully treated by surgical or radiological treatment. 2) The high prevalence of clinically silent tumor in thyroid gland has been reported. The incidence of thyroid cancer, therefore, is very dependent on methods of medical inspection. The prevalence of radiation induced thyroid cancer is modified by various factors such as age, sex, latency, dose and dose rate. The latent period is very important factors such as ave, sex, latency, dose and dose rate. The latent period is a very important factor in the estimation of accumulated total risk of thyroid malignancy. What is included in the risk caused by thyroid irradiation must be investigated. The risk of non-fatal cancer should be considered in the same way as that of fatal cancer. The dose-equivalent limit of thyroid in non-uniform irradiation caused by radioactive iodine is decided by the limit for non-stochastic effects. Therefore the further consideration of non-stochastic effects of thyroid is necessary. (author)

This paper describes results from a model of decision-making under uncertainty using a real options methodology, developed by the International Energy Agency (IEA). The model represents investment decisions in power generation from the perspective of a private company. The investments are subject to uncertain future climate policy, which is treated as an external risk factor over which the company has no control. The aims of this paper are to (i) quantify these regulatory risks in order to improve understanding of how policy uncertainty may affect investment behaviour by private companies and (ii) illustrate the effectiveness of the real options approach as a policy analysis tool. The study analysed firms' investment options of coal- and gas-fired power plants and carbon capture and storage (CCS) technologies. Policy uncertainty is represented as an exogenous event that creates uncertainty in the carbon price. Our findings indicate that climate policy uncertainty creates a risk premium for power generation investments. In the case of gas- and coal-fired power generation, the risk premium would lead to an increase in electricity prices of 5-10% in order to stimulate investment. In the case of CCS, the risk premium would increase the carbon price required to stimulate investment by 16-37% compared to a situation of perfect certainty. The option to retrofit CCS acts as a hedge against high future carbon prices, and could accelerate investment in coal plant. This paper concludes that to minimise investment risks in low carbon technologies, policy-makers should aim to provide some long-term regulatory certainty. (author)

Insurers hope to make profit through pooling policies from a large number of individuals. Unless the risk in question is similar for all potential customers, an insurer is exposed to the possibility of adverse selection by attracting only high-risk individuals. To counter this, insurers have traditionally employed underwriting principles, identifying suitable risk factors to subdivide their potential customers into homogeneous risk groups, based on which risk-related premiums can be charged. ...

A new model of the etiology of sexual harassment, the four-factor model, is presented and compared with several models of sexual harassment including the biological model, the organizational model, the sociocultural model, and the sex role spillover model. A number of risk factors associated with sexually harassing behavior are examined within the framework of the four-factor model of sexual harassment. These include characteristics of the work environment (e.g., sexist attitudes among co-workers, unprofessional work environment, skewed sex ratios in the workplace, knowledge of grievance procedures for sexual harassment incidents) as well as personal characteristics of the subject (e.g., physical attractiveness, job status, sex-role). Subjects were 266 university female faculty, staff, and students who completed the Sexual Experience Questionnaire to assess the experience of sexual harassment and a questionnaire designed to assess the risk factors stated above. Results indicated that the four-factor model is a better predictor of sexual harassment than the alternative models. The risk factors most strongly associated with sexual harassment were an unprofessional environment in the workplace, sexist atmosphere, and lack of knowledge about the organization's formal grievance procedures.

Full Text Available The authors review environmental and neurodevelopmental risk factors for schizophrenic disorders, with emphasis on minor physical anomalies, particularly craniofacial anomalies and dermatoglyphic variations. The high prevalence of these anomalies among schizophrenic subjects supports the neurodevelopmental theory of the etiology of schizophrenia, since they suggest either genetically or epigenetically controlled faulty embryonic development of structures of ectodermal origin like brain and skin. This may disturb neurodevelopment that in turn may cause these subjects to be at increased risk for the development of schizophrenia and related disorders. The precise confirmation of this theory, at least in some cases, will provide further understanding of these illnesses, allowing easy and inexpensive identification of subjects at risk and providing guidelines for the development of new pharmacological interventions for early treatment and even for primary prevention of the illness.

The HIV/AIDS epidemic in China is growing and the main transmission mode has changed from contaminated blood products to sexual contact. The aim of this study was to evaluate the levels of anxiety (SAS; Zung Self-Rating Anxiety Scale) and depression (CES-D; Center for Epidemiologic Studies Depression Scale) among people living with HIV/AIDS (PLWHA) under the new epidemic characteristics and to examine associated factors. The sample size (N=800) was calculated on the basis of the lowest prevalence of psychological disorders among PLWHA and was enlarged taking into consideration a loss of response. Participants were sampled randomly among all PLWHA registered in Liaoning Province. Questionnaires pertaining to the SAS, CES-D, and related factors were distributed between December 2010 and April 2011; 772 effective responses were received. The prevalence of anxiety (SAS ≥40) and depression (CES-D ≥16) were 49.0% and 73.1%, respectively. Multivariate logistic regression analysis revealed that SAS was associated with self-rated health, condom use at the last sexual contact, perceived social support, alcohol consumption, and transmission; CES-D was associated with self-rated health, perceived social support, job, and sex. PLWHA under the new epidemic characteristics in China suffer from serious psychological problems. To improve their psychological well-being, efforts should be focused on improving perceptions of their health condition and increasing perceived social support.

Background: The magnitude of under nutrition among children below five years of age is high in Pakistan. Undernutrition and infections are the two most important factors that affect the growth of children. This study explains the extent of undernutrition and prevalence of wasting and stunting among preschool children. Method: This cross sectional study with a sample size of 446 covered the age group 6-59 months in Jalozai Camp, District Nowshera. Height for age, weight for age and weight for height were measured as per WHO guidelines. Systematic random sampling technique was used for sample selection. Data was collected using a questionnaire. Results: According to height for age Z-score, out of 446 children studied, 8.5 percentage were stunted and 4.0 percentage were severely stunted. According to weight for age Z score, 11.4 percentage were underweight and 3.6 percentage were severely underweight. According to weight for height Z-score, 4.0 percentage were wasted and 2.7 percentage were severely wasted. Conclusion: The undernutrition in children is comparable to the national figures. Although our study found that absence of formal education, big family size, late and early weaning, absence of exclusive breast feeding and poverty were the factors associated with undernutrition in children, they could cause increase in under nutrition in future if not improved.

Risk-based planning offers a robust way to identify strategies that permit adaptive water resources management under climate change. This paper presents a flexible methodology for conducting climate change risk assessments involving reservoir operations. Decision makers can apply this methodology to their systems by selecting future periods and risk metrics relevant to their planning questions and by collectively evaluating system impacts relative to an ensemble of climate projection scenarios (weighted or not). This paper shows multiple applications of this methodology in a case study involving California's Central Valley Project and State Water Project systems. Multiple applications were conducted to show how choices made in conducting the risk assessment, choices known as analytical design decisions, can affect assessed risk. Specifically, risk was reanalyzed for every choice combination of two design decisions: (1) whether to assume climate change will influence flood-control constraints on water supply operations (and how), and (2) whether to weight climate change scenarios (and how). Results show that assessed risk would motivate different planning pathways depending on decision-maker attitudes toward risk (e.g., risk neutral versus risk averse). Results also show that assessed risk at a given risk attitude is sensitive to the analytical design choices listed above, with the choice of whether to adjust flood-control rules under climate change having considerably more influence than the choice on whether to weight climate scenarios.

The aim of the present study was to investigate the rate of post-tonsillectomy hemorrhage (PTH) in a single institution and to evaluate the clinical risk factors for PTH. We reviewed the records of 692 patients who underwent tonsillectomy (TE) at Yokohama Minami Kyosai Hospital in Japan. PTH grades were grouped into three categories according to the severity of the hemorrhagic episode: (I) minimal hemorrhage that stopped after noninvasive treatment, (II) hemorrhage requiring treatment with local anesthesia, and (III) hemorrhage requiring reoperation under general anesthesia in the operating room. Clinical risk factors such as sex, age (adults vs. children), TE indication, surgeon's skill level, operative time, ligature type, and duration of antibiotic administration for PTH were investigated. Among the 692 patients, 80 (11.6%) showed PTH, with primary and secondary hemorrhage accounting for 1.6% and 10.0%, respectively. A category III PTH was observed in 18 patients; thus, the overall risk of reoperation was 2.6%. The PTH episode most frequently occurred on postoperative days 5 and 6. The frequency of PTH was significantly higher in male patients and in adults (Pdefinition of PTH. Clinical risk factors for PTH were adult age and male gender. The surgeon's skill level was an additional risk factor for category III PTH. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

The study gives a survey of the factors most frequently mentioned in the literature as factors likely to adversely affect a pregnancy. One essential aspect is the discussion of those factors that can be counted among the causes of malformations, as among others, prenatal radiation exposure. The study prepared within the framework of the research project 'Radiobiological environmental monitoring in Bavaria' is intended to serve as a basis for a retrospective and prospective evaluation of infant mortality, perinatal conditions and occurrence of malformations in Bavaria, with the principal idea of drawing up an environment - related health survey. The study therefore, in addition to ionizing radiation also takes into account other detectable risks within the ecologic context, as e.g. industrial installations, refuse incineration plants or waste dumps, or urbanity.

Tornadoes in North and South Carolina on 28 March 1984 caused 252 people to be injured seriously enough to require hospitalization and 59 to be killed. To evaluate risk factors, we gathered information on 238 (94%) of those hospitalized and 46 (78%) of those killed. Those hospitalized or deceased had statistically significantly more deep cuts, concussions, unconsciousness and broken bones than those with them at the time of the tornado who were not hospitalized or killed. People living in mobile homes were more likely to be hospitalized or die than people occupying conventional houses. Other risk factors for hospitalization or death included advanced age (60+ years), no physical protection (not having been covered with a blanket or other object), having been struck by broken window glass or other falling objects, home lifted off its foundation, collapsed ceiling or floor, or walls blown away. More awareness of the tornado risk before it strikes and better adherence to tornado protection guidelines could reduce injuries and deaths in the future.

Our purpose is to discuss established risk factors in the development of acute renal failure and briefly overview clinical markers and preventive measures. Findings from the literature support the role of older age, diabetes, underlying renal insufficiency, and heart failure as predisposing factors for acute renal failure. Diabetics with baseline renal insufficiency represent the highest risk subgroup. An association between sepsis, hypovolemia, and acute renal failure is clear. Liver failure, rhabdomyolysis, and open-heart surgery (especially valve replacement) are clinical conditions potentially leading to acute renal failure. Increasing evidence shows that intraabdominal hypertension may contribute to the development of acute renal failure. Radiocontrast and antimicrobial agents are the most common causes of nephrotoxic acute renal failure. In terms of prevention, avoiding nephrotoxins when possible is certainly desirable; fluid therapy is an effective prevention measure in certain clinical circumstances. Supporting cardiac output, mean arterial pressure, and renal perfusion pressure are indicated to reduce the risk for acute renal failure. Nonionic, isoosmolar intravenous contrast should be used in high-risk patients. Although urine output and serum creatinine lack sensitivity and specificity in acute renal failure, they remain the most used parameters in clinical practice. There are identified risk factors of acute renal failure. Because acute renal failure is associated with a worsening outcome, particularly if occurring in critical illness and if severe enough to require renal replacement therapy, preventive measures should be part of appropriate management.

Despite the advances in interventional techniques, the management of stable atherosclerosis remains the domain of optimal guideline-oriented therapy. Recent studies on the effects of aggressive lipid lowering on atheroma volume changes using intravascular ultrasound indicate that it is possible to achieve atherosclerosis regression by reaching low-density lipoprotein (LDL) levels less than 75 mg/dl. The pleiotropic anti-inflammatory effects of statins contribute to the reduction of cardiovascular (CV) event observed with aggressive lipid lowering. As a second important strategy to prevent disease progression, lifestyle changes with regular physical exercise are capable of halting the atherosclerotic process and reducing angina symptoms and CV events. Optimal medical therapy, a healthy lifestyle with regular physical exercise, and coronary interventions are not mutually exclusive treatment strategies. Over the last few decades, both have proved to be effective in significantly reducing the CV mortality in the Western world. However, risk factor modification contributed to at least half the effect in the reduction of CV mortality. This figure provides an estimate of what could be achieved if we were to take risk factor modification more seriously - especially in the acute care setting. The knowledge is there: today we have a better understanding on how to stop progression and even induce regression of atherosclerosis. Much research still needs to be done and will be done. In the meantime, however, our primary focus should lie in implementing what is already known. In addition, it is essential not just to treat CV risk factors, but also to treat them to achieve the target values as set by the guidelines of European Society of Cardiology.

Beekeepers all across the world are suffering important losses of their colonies, and the parasitic mites Varroa destructor and Nosema sp, as well as several bee viruses, are being pointed out as the possible causes of these losses, generally associated with environmental and management factors. The objective of the present study was to evaluate the presence of seven virus species (Deformed wing virus -DWV-, Acute bee paralysis virus -ABPV-, Chronic bee paralysis virus -CBPV-, Black queen cell virus -BQCV-, Kashmir bee virus -KBV-, Israeli acute bee paralysis virus -IAPV-, and Sacbrood bee virus -SBV), as well as the prevalence of Nosema sp. and Varroa destructor, and their possible associated factors, under temperate and subtropical climate conditions in Argentinean colonies. A total of 385 colonies distributed in five Argentinean eco-regions were examined after honey harvest. The final multivariable model revealed only one variable associated with the presence of DWV and two with the presence of ABPV. The apiary random effect was significant in both cases (P=0.018; P=0.006, respectively). Colonies with a Varroa infestation rate >3% showed higher presence of DWV than colonies with <3% of Varroa infestation level (OR=1.91; 95% CI: 1.02-3.57; P<0.044). The same pattern was observed for the presence of ABPV (OR=2.23; 95% CI: 1.04-4.77; P<0.039). Also, colonies where replacement of old combs was not a common practice had higher presence of ABPV (OR=6.02; 95% CI: 1.16-31.25; P<0.033). Regardless of the location of the colonies, virus presence was strongly associated with V. destructor level. Therefore, all the factors that directly or indirectly influence the levels of mites will be also influencing the presence of the viruses. Copyright © 2017 Elsevier B.V. All rights reserved.

Low self-esteem has been shown to relate to concurrent and later feelings of loneliness in adolescence. However, it remains unclear why low self-esteem puts adolescents at risk for experiencing loneliness. Further, longitudinal research on the direction of effects between loneliness and self-esteem is virtually non-existent. The present study aims to fill these gaps in the literature. First, the direction of effects between loneliness and self-esteem was investigated in two independent longitudinal studies: a five-wave study sampling Dutch adolescents (M age = 15.22 years at T1; 47 % female; N = 428) and a three-wave study sampling Belgian adolescents (M age = 14.95 years at T1; 63 % female; N = 882). Second, the underlying role of social acceptance was investigated in the latter sample by applying a multi-method approach that included actual (i.e., peer-reported) and perceived (i.e., self-reported) social acceptance. Results indicated that self-esteem and loneliness influenced one another in a reciprocal manner. Furthermore, the dominant path from self-esteem to loneliness was partially mediated by perceived--but not actual--social acceptance. The importance of distinguishing actual from perceived social acceptance is discussed, and suggestions for future research are outlined.
Full Text Available The objective of the article is to analyse and present the classification of risks actual to derivative securities. The analysis is based on classical and modern literature findings and analysis of newest statistical data. The analysis led to the conclusion, that the main risks typical for derivatives contracts and their traders are market risk, liquidity risk, credit and counterparty risk, legal risk and transactions risk. Pricing risk and systemic risk is also quite important. The analysis showed that market risk is the most important kind of risk that in many situations influences the level of remaining risks.

Decision making under risk is central to human behavior. Economic decision theory suggests that value, risk, and risk aversion influence choice behavior. Although previous studies identified neural correlates of decision parameters, the contribution of these correlates to actual choices is unknown. In two different experiments, participants chose between risky and safe options. We identified discrete blood oxygen level-dependent (BOLD) correlates of value and risk in the ventral striatum and anterior cingulate, respectively. Notably, increasing inferior frontal gyrus activity to low risk and safe options correlated with higher risk aversion. Importantly, the combination of these BOLD responses effectively decoded the behavioral choice. Striatal value and cingulate risk responses increased the probability of a risky choice, whereas inferior frontal gyrus responses showed the inverse relationship. These findings suggest that the BOLD correlates of decision factors are appropriate for an ideal observer to detect behavioral choices. More generally, these biological data contribute to the validity of the theoretical decision parameters for actual decisions under risk.

Schizophrenia (SZ) is a complex and strongly heritable mental disorder, which is also associated with developmental-environmental triggers. As opposed to most diagnosable diseases (yet similar to other mental disorders), SZ diagnosis is commonly based on psychiatric evaluations. Recently, large-scale genetic and epigenetic approaches have been applied to SZ research with the goal of potentially improving diagnosis. Increased computational analyses and applied statistical algorithms may shed some light on the complex genetic and epigenetic pathways contributing to SZ pathogenesis. This review discusses the latest advances in molecular risk factors and diagnostics for SZ. Approaches such as these may lead to a more accurate definition of SZ and assist in creating extended and reliable clinical diagnoses with the potential for personalized treatment.

Individual differences in attitudes to risk (a taste for risk, known probabilities) and ambiguity (a tolerance for uncertainty, unknown probabilities) differentially influence risky decision-making. However, it is not well understood whether risk and ambiguity are coded differently within individuals. Here, we tested whether individual differences in risk and ambiguity attitudes were reflected in distinct neural correlates during choice and outcome processing of risky and ambiguous gambles. To these ends, we developed a neuroimaging task in which participants ( n = 50) chose between a sure gain and a gamble, which was either risky or ambiguous, and presented decision outcomes (gains, no gains). From a separate task in which the amount, probability, and ambiguity level were varied, we estimated individuals' risk and ambiguity attitudes. Although there was pronounced neural overlap between risky and ambiguous gambling in a network typically related to decision-making under uncertainty, relatively more risk-seeking attitudes were associated with increased activation in valuation regions of the brain (medial and lateral OFC), whereas relatively more ambiguity-seeking attitudes were related to temporal cortex activation. In addition, although striatum activation was observed during reward processing irrespective of a prior risky or ambiguous gamble, reward processing after an ambiguous gamble resulted in enhanced dorsomedial PFC activation, possibly functioning as a general signal of uncertainty coding. These findings suggest that different neural mechanisms reflect individual differences in risk and ambiguity attitudes and that risk and ambiguity may impact overt risk-taking behavior in different ways.
Full Text Available Under standard models of expected utility, preferences over stochastic events are assumed to be independent of the source of uncertainty. Thus, in decision-making, an agent should exhibit consistent preferences, regardless of whether the uncertainty derives from the unpredictability of a random process or the unpredictability of a social partner. However, when a social partner is the source of uncertainty, social preferences can influence decisions over and above pure risk attitudes. Here, we compared risk-related hemodynamic activity and individual preferences for two sets of options that differ only in the social or non-social nature of the risk. Risk preferences in social and non-social contexts were systematically related to neural activity during decision and outcome phases of each choice. Individuals who were more risk averse in the social context exhibited decreased risk-related activity in the amygdala during non-social decisions, while individuals who were more risk averse in the non-social context exhibited the opposite pattern. Differential risk preferences were similarly associated with hemodynamic activity in ventral striatum at the outcome of these decisions. These findings suggest that social preferences, including aversion to betrayal or exploitation by social partners, may be associated with variability in the response of these subcortical regions to social risk.

Probabilistic Risk Assessment (PRA) has proven to be an invaluable tool for evaluating risks in complex engineered systems. However, there is increasing concern that PRA may not be adequate in situations with little underlying knowledge to support probabilistic representation of uncertainties. As analysts and policy makers turn their attention to deeply uncertain hazards such as climate change, a number of alternatives to traditional PRA have been proposed. This paper systematically compares three diverse approaches for risk analysis under deep uncertainty (qualitative uncertainty factors, probability bounds, and robust decision making) in terms of their representation of uncertain quantities, analytical output, and implications for risk management. A simple example problem is used to highlight differences in the way that each method relates to the traditional risk assessment process and fundamental issues associated with risk assessment and description. We find that the implications for decision making are not necessarily consistent between approaches, and that differences in the representation of uncertain quantities and analytical output suggest contexts in which each method may be most appropriate. Finally, each methodology demonstrates how risk assessment can inform decision making in deeply uncertain contexts, informing more effective responses to risk problems characterized by deep uncertainty. - Highlights: • We compare three diverse approaches to risk assessment under deep uncertainty. • A simple example problem highlights differences in analytical process and results. • Results demonstrate how methodological choices can impact risk assessment results.

Full Text Available The goal of the present study is to identify the risk factors for developing diabetic foot. A cross-sectional study, with a convenience sample, developed with 70 individuals with diabetes mellitus (DM, registered in three basic health units in the municipality of Florianópolis/SC, Brazil, in the period from November 2010 to May 2011. Biometric data was collected regarding their sociodemographic, health and illness conditions. An assessment of the feet was also carried out. The average participant age was 66.17 years and time with diagnosed disease was under ten years (61.42%. The following risk factors were identified: advanced age; time of DM diagnosis; few years of schooling; overweight/obesity; inadequate diet; physical inactivity; inadequate metabolic control; lack of proper and specific foot care; and arterial hypertension. We conclude that the majority of the population presented one or more risk factors that favor the appearance of foot-related complications. doi: 10.5216/ree.v16i2.20460.
Risk factors for mortality from acute lower respiratory infections (ALRI in children under five years of age in low and middle-income countries: a systematic review and meta-analysis of observational studies.
Full Text Available OBJECTIVE: To evaluate risk factors for death from acute lower respiratory infections (ALRI in children in low- and middle-income countries. DESIGN: Systematic review and meta-analysis. STUDY SELECTION: Observational studies reporting on risk factors for death from ALRI in children below five years in low- and middle income countries. DATA SOURCES: Medline, Embase, Global Health Library, Lilacs, and Web of Science to January 2014. RISK OF BIAS ASSESSMENT: Quality In Prognosis Studies tool with minor adaptations to assess the risk of bias; funnel plots and Egger's test to evaluate publication bias. RESULTS: Out of 10,655 papers retrieved, 77 studies from 39 countries (198,359 children met the inclusion criteria. Host and disease characteristics more strongly associated with ALRI mortality were: diagnosis of very severe pneumonia as per WHO definition (odds ratio 9.42, 95% confidence interval 6.37‒13.92; age below two months (5.22, 1.70‒16.03; diagnosis of Pneumocystis Carinii (4.79, 2.67‒8.61, chronic underlying diseases (4.76, 3.27‒6.93; HIV/AIDS (4.68, 3.72‒5.90; and severe malnutrition (OR 4.27, 3.47‒5.25. Socio-economic and environmental factors significantly associated with increased odds of death from ALRI were: young maternal age (1.84, 1.03‒3.31; low maternal education (1.43, 1.13‒1.82; low socio-economic status (1.62, 1.32‒2.00; second-hand smoke exposure (1.52, 1.20 to 1.93; indoor air pollution (3.02, 2.11‒4.31. Immunisation (0.46, 0.36‒0.58 and good antenatal practices (0.50, 0.31‒0.81 were associated with decreased odds of death. CONCLUSIONS: Host and disease characteristics as well as socio-economic and environmental determinants affect the risk of death from ALRI in children. Together with the prevention and treatment of chronic diseases, interventions to modify underlying risk factors such as poverty, lack of female education, and poor environmental conditions, should be considered among the strategies to

Many air-breathing aquatic foragers may be killed by aerial or subsurface predators while recovering oxygen at the surface; yet the influence of predation risk on time allocation during dive cycles is little known in spite of numerous studies on optimal diving. We modeled diving behavior under the risk of predation at the surface. The relationship between time spent at the surface and the risk of death is predicted to influence the optimal surface interval, regardless of whether foragers accumulate energy at a constant rate while at the food patch, deplete food resources over the course of the dive, or must search for food during the dive. When instantaneous predation risk during a single surface interval decreases with time spent at the surface, a diver should increase its surface interval relative to that which maximizes energy intake, thereby increasing dive durations and reducing the number of surfacings per foraging bout. When instantaneous risk over a single surface interval does not change or increases with increasing time at the surface, divers should decrease their surface interval (and consequently their dive duration) relative to that which maximizes energy intake resulting in more dives per foraging bout. The fitness consequences of selecting a suboptimal surface interval vary with the risk function and the way divers harvest energy when at depth. Finally, predation risk during surface intervals should have important consequences for habitat selection and other aspects of the behavioral ecology of air-breathing aquatic organisms.

Full Text Available Background: Leptospirosis is one of the most under diagnosed and underreported disease in both developed and developing countries including India. It is established that environmental conditions and occupational habit of the individuals put them at risk of acquiring disease, which varies from community to community. Various seroprevalence studies across the world have documented emerging situation of this neglected tropical disease, but limited have probed to identify the risk factors, especially in India. Objectives: The objective of this study was to identify the environmental and occupational risk factors associated with the disease in Udupi District. Materials and Methods: This population-based case-control study was carried out in Udupi, a District in Southern India from April 2012 until August 2012. Udupi is considered to be endemic for Leptospirosis and reported 116 confirmed cases in the year 2011. Seventy of 116 laboratory confirmed cases and 140 sex matched neighborhood healthy controls participated in the study. A predesigned, semi-structured and validated questionnaire was used for data collection through house to house visit and observations were noted about environmental conditions. Univariate analysis followed by multivariate analysis (back ward conditional logistic regression was performed by using STATA version 9.2 (StataCorp, College Station, TX, USA to identify potential risk factors. Results: Occupational factors such as outdoor activities (matched odds ratio [OR] of 3.95, 95% confidence interval [CI]: 1.19-13.0, presence of cut or wound at body parts during work (matched OR: 4.88, CI: 1.83-13.02 and environmental factors such as contact with rodents through using the food materials ate by rat (matched OR: 4.29, CI: 1.45-12.73 and contact with soil or water contaminated with urine of rat (matched OR: 4.58, CI: 1.43-14.67 were the risk factors identified to be associated with disease.

Although meta-analyses provide summary effect estimates that help advise patient care, patients often want to compare their overall health to the general population. The Harvard Cancer Risk Index was published in 2004 and uses risk ratio estimates and prevalence estimates from original studies across many risk factors to provide an answer to this question. However, the published version of the formula only uses dichotomous risk factors and its derivation was not provided. The objective of this brief report was to provide the derivation of a more general form of the equation that allows the incorporation of risk factors with three or more levels.

Systemic hypertension is one of the main risk factors for cardiovascular disease (CVD). Early diagnosis and treatment of hypertension in childhood can potentially have a significant impact on future adverse outcomes. To investigate the relationship of diastolic (DBP) and systolic blood pressure (SBP) with anthropometric data and area of residence of children in municipalities of Rio Grande do Sul state, Brazil. This is a cross-sectional study of 709 children between six and nine years of age. Blood pressure, weight, height and waist circumference (WC) were measured. Statistical tests had a maximum significance level of 5% (p≤0.05) and the software used was SPSS version 13.0. Obesity was significantly associated with pre-hypertension, and stage 1 and 2 hypertension as assessed by DBP and SBP (≤0.05); high WC was significantly associated with a classification of pre-hypertension and stage 1 hypertension based on DBP and a classification of stage 1 and 2 hypertension based on SBP (≤0.01). Children living in urban areas had significantly higher mean SBP than those living in rural areas. Those with high WC presented higher SBP and DBP compared to children with normal WC. Obese children showed higher mean SBP and DBP compared to those who were overweight or normal weight and mean SBP and DBP also increased with older age and higher mean body mass index and WC.

Positively autocorrelated red environmental noise is characterized by a strong dependence of expected sample variance on sample length. This dependence has to be taken into account when assessing extinction risk under red and white uncorrelated environmental noise. To facilitate a comparison between red and white noise, their expected variances can be scaled to be equal, but only at a chosen time scale. We show with a simple one-dimensional population dynamics model that the different but equ...

Prior to commencing a campaign to eliminate blinding trachoma in Mali, a national disease prevalence survey was conducted from March 1996 to June 1997. The prevalence of trachoma was estimated and potential risk factors were studied. In each of Mali's seven regions (excluding the capital Bamako), a sample of 30 clusters was taken from the general population, in accordance with the principle of probability proportional to the size of the community. All children under 10 years of age were examined. The simplified clinical coding system proposed by the World Health Organization was used. The position of each village was established and subsequently related to the nearest meteorological station. Socioeconomic and environmental information was collected at both village and household level. The mother or caretaker of each child was questioned about availability and use of water for washing the child. At the time of examination, facial cleanliness and the presence of flies on the face were noted. A total of 15,187 children under 10 years of age were examined. The prevalence of active trachoma (follicular [TF] or intense trachoma [TI]) was 34.9% (95% CI : 32.3-37.6) and the prevalence of TI was 4.2% (95% CI : 3.5-5.0). Aridity/environmental dryness appears to be a risk factor influencing the current geographical distribution of trachoma. Small villages had considerably higher trachoma prevalence than their larger neighbours. The proximity of a medical centre and the existence of social organizations such as a women's association were associated with lower levels of trachoma. Crowded living conditions increased the risk. Using a monetary marker of wealth, we observed a linear inverse relation between wealth and trachoma prevalence. The presence of a dirty face was strongly associated with trachoma (odds ratio [OR] = 3.67) as was the presence of flies on the child's face (OR = 3.62). Trachoma prevalence increased with distance to a water source. Disease prevalence decreased

This study aimed to determine the prevalence of human respiratory syncytial virus (HRSV) acute respiratory infection (ARI) in children under the age of 5 years at the Provincial General Hospital of Bukavu (PGHB), and to analyse factors associated with the risk of ARI being diagnosed as lower respiratory tract infection (LRTI). A total of 146 children under 5 years visiting the PGHB for ARI between August and December 2016 were recruited, and socio-demographic information, clinical data and nasopharyngeal swabs were collected. The samples were analysed by a multiplex reverse transcriptase polymerase chain reaction targeting 15 different viruses. Of 146 samples collected, 84 (57.5 %) displayed a positive result of at least one of the 15 viruses. The overall prevalence of HRSV was 21.2 %. HRSV A (30, 20.5 %) was the virus the most detected, followed by HRV (24, 16.4 %), PIV3 (20, 16.6) and ADV (7, 4.79 %). The other viruses were detected in three or fewer cases. There were only 11 (7.5 %) cases of co-infection. HRSV infection, malnutrition, younger age, rural settings, low income and mother illiteracy were associated with the risk of ARI being diagnosed as LRTI in bivariate analyses but, after adjusting for the confounding factors, only HRSV infection and younger age were independently associated with LRTI. The prevalence of HRSV is high among children visiting the PGHB for ARI. HRSV infection and lower age are independently associated with the risk of ARI being diagnosed as LRTI.

The paper considers vulnerable multi-state series-parallel systems operating under influence of external impacts. Both the external impacts and internal failures affect system survivability, which is determined as the probability of meeting a given demand. The external impacts are characterized by several destructive factors affecting the system or its parts simultaneously. In order to increase the system's survivability a multilevel protection against the destructive factors can be applied to its subsystems. In such systems, the protected subsystems can be destroyed only if all of the levels of their protection are destroyed. The paper presents an algorithm for evaluating the survivability of series-parallel systems with arbitrary configuration of multilevel protection against multiple destructive factor impacts. The algorithm is based on a composition of Boolean and the Universal Generating Function techniques. Illustrative examples are presented

Full Text Available Epidemiological and clinical studies have shown that children exposed to adverse experiences are at increased risk for the development of depression, anxiety disorders and PTSD. A history of child abuse and maltreatment increases the likelihood of being subsequently exposed to traumatic events or of developing PTSD as an adult. The brain is highly plastic during early life and encodes acquired information into lasting memories that normally subserve adaptation. Translational studies in rodents showed that enduring sensitization of neuronal and neuroendocrine circuits in response to early life adversity are likely risk factors of life time vulnerability to stress. Hereby, the hypothalamic-pituitary-adrenal (HPA axis integrates cognitive, behavioural and emotional responses to early-life stress and can be epigenetically programmed during sensitive windows of development. Epigenetic mechanisms, comprising reciprocal regulation of chromatin structure and DNA methylation, are important to establish and maintain sustained, yet potentially reversible, changes in gene transcription. The relevance of these findings for the development of PTSD requires further studies in humans where experience-dependent epigenetic programming can additionally depend on genetic variation in the underlying substrates which may protect from or advance disease development. Overall, identification of early-life stress associated epigenetic risk markers informing on previous stress history can help to advance early diagnosis, personalized prevention and timely therapeutic interventions, thus reducing long-term social and health costs.

Full Text Available Background: Falls are common geriatric problems. The risk factors of falls are the intrinsic and extrinsic risk factors. Studies on falls are scarcely conducted in Indonesia, especially in Bandung. Therefore, this study was conducted to identify the intrinsic risk factors of falls among elderly. Methods: A descriptive study was carried out from August to October 2013 at the Geriatric Clinic of Dr. Hasan Sadikin General Hospital Bandung. Fifty three participants were selected according to the inclusion and exclusion criteria using consecutive sampling. The determined variables in this study were classification of the risk of falls, demographic profile, history of falls, disease, and medications. After the selection, the participants were tested by Timed up-and-go test (TUGT. Moreover, an interview and analysis of medical records were carried out to discover the risk factors of falls. The collected data were analyzed and presented in the form of percentages shown in tables. Results: From 53 patients, women (35.66% were considered to have higher risk of fall than men (18.34%. The majority of patients (66% with the risk of fall were from the age group 60–74 years. The major diseases suffered by patients were hypertension, osteoarthritis and diabetes mellitus. Drugs that were widely used were antihypertensive drugs; analgesic and antipyretic drugs and antidiabetic drugs. Conclusions: There are various intrinsic risk factors of falls in elderly and each of the elderly has more than one intrinsic risk factor of falls.

There has been a surge of diagnosis of autism spectrum disorders (ASD) over the past decade. While large, high powered genome screening studies of children with ASD have identified numerous genetic risk factors, research efforts to understanding how each of these risk factors contributes to the development autism has met with limited success. Revealing the mechanisms by which these genetic risk factors affect brain development and predispose a child to autism requires mechanistic understanding of the neurobiological changes underlying this devastating group of developmental disorders at multifaceted molecular, cellular and system levels. It has been increasingly clear that the normal trajectory of neurodevelopment is compromised in autism, in multiple domains as much as aberrant neuronal production, growth, functional maturation, patterned connectivity, and balanced excitation and inhibition of brain networks. Many autism risk factors identified in humans have been now reconstituted in experimental mouse models to allow mechanistic interrogation of the biological role of the risk gene. Studies utilizing these mouse models have revealed that underlying the enormous heterogeneity of perturbed cellular events, mechanisms directing synaptic and circuit assembly may provide a unifying explanation for the pathophysiological changes and behavioral endophenotypes seen in autism, although synaptic perturbations are far from being the only alterations relevant for ASD. In this review, we discuss synaptic and circuit abnormalities obtained from several prevalent mouse models, particularly those reflecting syndromic forms of ASD that are caused by single gene perturbations. These compiled results reveal that ASD risk genes contribute to proper signaling of the developing gene networks that maintain synaptic and circuit homeostasis, which is fundamental to normal brain development.

Headache is a chronic disease that occurs with varying frequency and results in varying levels of disability. To date, the majority of research and clinical focus has been on the role of biological factors in headache and headache-related disability. However, reliance on a purely biomedical model of headache does not account for all aspects of headache and associated disability. Using a biopsychosocial framework, the current manuscript expands the view of what factors influence headache by considering the role psychological (i.e., cognitive and affective) factors have in the development, course, and consequences of headache. The manuscript initially reviews evidence showing that neural circuits responsible for cognitive–affective phenomena are highly interconnected with the circuitry responsible for headache pain. The manuscript then reviews the influence cognitions (locus of control and self-efficacy) and negative affect (depression, anxiety, and anger) have on the development of headache attacks, perception of headache pain, adherence to prescribed treatment, headache treatment outcome, and headache-related disability. The manuscript concludes with a discussion of the clinical implications of considering psychological factors when treating headache. PMID:17371358

The communication of natural hazards and their consequences is one of the more relevant ethical issues faced by scientists. In the last years, social studies have provided evidence that risk communication is strongly influenced by the risk perception of people. In order to develop effective information and risk communication strategies, the perception of risks and the influencing factors should be known. A theory that offers an integrative approach to understanding and explaining risk perception is still missing. To explain risk perception, it is necessary to consider several perspectives: social, psychological and cultural perspectives and their interactions. This paper presents the results of the CATI survey on seismic risk perception in Italy, conducted by INGV researchers on funding by the DPC. We built a questionnaire to assess seismic risk perception, with a particular attention to compare hazard, vulnerability and exposure perception with the real data of the same factors. The Seismic Risk Perception Questionnaire (SRP-Q) is designed by semantic differential method, using opposite terms on a Likert scale to seven points. The questionnaire allows to obtain the scores of five risk indicators: Hazard, Exposure, Vulnerability, People and Community, Earthquake Phenomenon. The questionnaire was administered by telephone interview (C.A.T.I.) on a statistical sample at national level of over 4,000 people, in the period January -February 2015. Results show that risk perception seems be underestimated for all indicators considered. In particular scores of seismic Vulnerability factor are extremely low compared with house information data of the respondents. Other data collected by the questionnaire regard Earthquake information level, Sources of information, Earthquake occurrence with respect to other natural hazards, participation at risk reduction activities and level of involvement. Research on risk perception aims to aid risk analysis and policy-making by

Schizophrenia is a severe mental disorder that affects approximately one percent of the general population. The pathogenesis of schizophrenia is influenced by many risk factors, both environmental and genetic. The environmental factors include the date of birth, place of birth and seasonal effects, infectious diseases, complications during pregnancy and delivery, substance abuse and stress. At the present time, in addition to environmental factors, genetic factors are assumed to play a role in the development of the schizophrenia. The heritability of schizo- phrenia is up to 80%. If one parent suffers from the condition, the probability that it will be passed down to the offspring is 13%. If it is present in both parents, the risk is more than 20%. The opinions are varied as to the risk factors affecting the development of schizophrenia. Knowing these factors may greatly contribute to prevention of the condition.

Mass media have numerous effects on children, ranging from influencing school performance to increased or reduced aggression. What we do not know, however, is how media availability in the bedroom moderates these effects. Although several researchers have suggested that bedroom media may influence outcomes by displacing other activities (the displacement hypothesis) or by changing the content of media consumed (the content hypothesis), these have rarely been tested directly. This study tested both hypotheses using several outcomes that are associated with bedroom media and some of the underlying mediating mechanisms. The hypotheses were tested using 3 longitudinal samples of varying methods, age, duration, and country. The results indicate that children who have bedroom media are likely to watch larger amounts of screen time which displaced important activities, such as reading and sleeping, which mediated later negative outcomes such as poor school performance. Bedroom media also influence risk for obesity and video game addiction. Children with bedroom media are also likely to be exposed to more media violence. The violent content increased normative beliefs about aggression, which increased physical aggression, providing support for the content hypothesis. This study demonstrates that media can have effects not just from what they show, but also because of what children are not exposed to. Bedroom media are therefore a robust risk factor for several aspects of child development. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

In the last years, there has been a change in the aetiology of spinal cord injury. There has been an increase in the number of elderly patients with spinal cord injuries caused by diseases or medical procedures. The aim of this study is to investigate the frequency of the occurrence of iatrogenic spinal cord injury in our unit. The secondary aim is to study what variables can be associated with a higher risk of iatrogenesis. A retrospective, descriptive, observational study of patients with acute spinal cord injury admitted from June 2009 to May 2014 was conducted. The information collected included the patient age, aetiology, neurological level and grade of injury when admitted and when discharged, cardiovascular risk factors, a previous history of depression and any prior treatment with anticoagulant or antiplatelet drugs. We applied a logistic regression. The grade of statistical significance was established as Pinjury was the thoracic level (48%). The main aetiology of spinal cord injury caused by iatrogenesis was surgery for degenerative spine disease, in patients under the age of 30 were treated with intrathecal chemotherapy. Iatrogenic spinal cord injury is a frequent complication. A statistically significant association between a patient history of depression and iatrogenic spinal cord injury was found as well as with anticoagulant and antiplatelet drug use prior to iatrogenic spinal cord injury.

Homelessness among US veterans has been a focus of research for over 3 decades. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this is the first systematic review to summarize research on risk factors for homelessness among US veterans and to evaluate the evidence for these risk factors. Thirty-one studies published from 1987 to 2014 were divided into 3 categories: more rigorous studies, less rigorous studies, and studies comparing homeless veterans with homeless nonveterans. The strongest and most consistent risk factors were substance use disorders and mental illness, followed by low income and other income-related factors. There was some evidence that social isolation, adverse childhood experiences, and past incarceration were also important risk factors. Veterans, especially those who served since the advent of the all-volunteer force, were at greater risk for homelessness than other adults. Homeless veterans were generally older, better educated, and more likely to be male, married/have been married, and to have health insurance coverage than other homeless adults. More studies simultaneously addressing premilitary, military, and postmilitary risk factors for veteran homelessness are needed. This review identifies substance use disorders, mental illness, and low income as targets for policies and programs in efforts to end homelessness among veterans. PMID:25595171

Congenital heart disease (CHD) is associated with multiple risk factors, consanguinity may be one such significant factor. The role of consanguinity in the etiology of CHD is supported by inbreeding studies, which demonstrate an autosomal recessive pattern of inheritance of some congenital heart defects. This study was done to find out the risk factors for CHD. A case-control study was done on pediatric patients at a tertiary care hospital, Aga Khan University Hospital, located in Karachi, Pakistan. A total of 500 patients, 250 cases and 250 controls were included in the study. Amongst the 250 cases (i.e. those diagnosed with CHD), 122 patients (48.8%) were born of consanguineous marriages while in the controls (i.e. non-CHD) only 72 patients (28.9%) showed a consanguinity amongst parents. On multivariate analysis, consanguinity emerged as an independent risk factor for CHD; adjusted odds ratio 2.59 (95% C. I. 1.73 - 3.87). Other risk factors included low birth weight, maternal co-morbidities, family history of CHD and first born child. On the other hand, medications used by the mother during the index pregnancy, maternal age and gender of the child did not significantly increase the risk of developing CHD. Analyses of our results show that parental consanguinity, family history of CHD, maternal co-morbidities, first born child and low birth weight are independent risk factors for CHD

Full Text Available Objective to analyze the impact of economic crisis in Russia on the enterprisesrsquo access to productive resources as well as on the level of their competencies. Methods historical abstractlogical. Results the article states that despite the influence of external factors the main activities of the company are internal capabilities and resources of the firm. It is shown that under crisis a company must adapt to the limited resources i.e. change the competences of using them. Under modern conditions the competitive advantage can be based on two components ndash access to resources and internal ability of the company to use them. Therefore under the resource constraints such competencies should be generated as 1 ability to use a smaller amount of resources 2 more efficient use of available resources 3 search for the new resources development of own resources. The study determined that the acquisition of new competencies by the company will be associated with the use and improvement of its cognitive capabilities which are a function of organizational and individual knowledge possessed by the enterprise i.e. its intellectual capital. The article analyses the experience of development of new competencies under crisis by the example of reorganization of quotPrompriborquot plant and activities of quotGalogenquot JSC. Analysis of the experience of these companies which not only survived during the crisis but also acquired new competences and skills have led to the conclusion that the key role in this process was played by working with the main part of a company39s intellectual capital i.e. human capital. Thus a conclusion is made about the value of people and their common interests during the transformations within the enterprise.

From the point of view of occupational health, the field of voice disorders is very poorly developed as compared, for instance, to the prevention and diagnostics of occupational hearing disorders. In fact, voice disorders have not even been recognized in the field of occupational medicine. Hence, it is obviously very rare in most countries that the voice disorder of a professional voice user, e.g. a teacher, a singer or an actor, is accepted as an occupational disease by insurance companies. However, occupational voice problems do not lack significance from the point of view of the patient. We also know from questionnaires and clinical studies that voice complaints are very common. Another example of job-related health problems, which has proved more successful in terms of its occupational health status, is the repetition strain injury of the elbow, i.e. the "tennis elbow". Its textbook definition could be used as such to describe an occupational voice disorder ("dysphonia professional is"). In the present paper the effects of such risk factors as vocal loading itself, background noise and room acoustics and low relative humidity of the air are discussed. Due to individual factors underlying the development of professional voice disorders, recommendations rather than regulations are called for. There are many simple and even relatively low-cost methods available for the prevention of vocal problems as well as for supporting rehabilitation.

Cholangiocarcinoma is the second most common primary malignant tumor of the liver. Perihilar cholangiocarcinoma or Klatskin tumor represents more than 50% of all biliary tract cholangiocarcinomas. A wide range of risk factors have been identified among patients with Perihilar cholangiocarcinoma including advanced age, male gender, primary sclerosing cholangitis, choledochal cysts, cholelithiasis, cholecystitis, parasitic infection (Opisthorchis viverrini and Clonorchis sinensis), inflammatory bowel disease, alcoholic cirrhosis, nonalcoholic cirrhosis, chronic pancreatitis and metabolic syndrome. Various classifications have been used to describe the pathologic and radiologic appearance of cholangiocarcinoma. The three systems most commonly used to evaluate Perihilar cholangiocarcinoma are the Bismuth-Corlette (BC) system, the Memorial Sloan-Kettering Cancer Center and the TNM classification. The BC classification provides preoperative assessment of local spread. The Memorial Sloan-Kettering cancer center proposes a staging system according to three factors related to local tumor extent: the location and extent of bile duct involvement, the presence or absence of portal venous invasion, and the presence or absence of hepatic lobar atrophy. The TNM classification, besides the usual descriptors, tumor, node and metastases, provides additional information concerning the possibility for the residual tumor (R) and the histological grade (G). Recently, in 2011, a new consensus classification for the Perihilar cholangiocarcinoma had been published. The consensus was organised by the European Hepato-Pancreato-Biliary Association which identified the need for a new staging system for this type of tumors. The classification includes information concerning biliary or vascular (portal or arterial) involvement, lymph node status or metastases, but also other essential aspects related to the surgical risk, such as remnant hepatic volume or the possibility of underlying disease.

Certain cardiovascular risk factors have been linked to morbidity and mortality in heart transplant (HT) patients. The sum of various risk factors may have a large cumulative negative effect, leading to a substantially worse prognosis and the need to consider whether HT is contraindicated. The objective of this study was to determine whether the risk factors usually available prior to HT result in an excess mortality in our setting that contraindicates transplantation. Consecutive patients who underwent heart transplantation from November 1987 to January 2004 were included. Heart-lung transplants, retransplants, and pediatric transplants were excluded. Of the 384 patients, 89% were men. Mean age was 52 years (range, 12 to 67). Underlying disease included ischemic heart disease (52%), idiopathic dilated cardiomyopathy (36%), valvular disease (8%), and other (4%). Variables considered risk factors were obesity (BMI >25), dyslipidemia, hypertension, prior thoracic surgery, diabetes, and history of ischemic heart disease. Survival curves by number of risk factors using Kaplan-Meier and log-rank for comparison of curves. Overall patient survival at 1, 5, 10, and 13 years was 76%, 68%, 54%, and 47%, respectively. Survival at 10 years, if fewer than two risk factors were present, was 69%; 59% if two or three factors were present; and 37% if more than three associated risk factors were present (P = .04). The presence of certain risk factors in patients undergoing HT resulted in lower survival rates. The combination of various risk factors clearly worsened outcomes. However, we do not believe this should be an absolute contraindication for transplantation.

Schizophrenia and autism are two poorly understood clinical syndromes that differ in age of onset and clinical profile. However, recent genetic and epidemiological research suggests that these two neurodevelopmental disorders share certain risk factors. The aims of this review are to describe modifiable risk factors that have been identified in both disorders, and, where available, collate salient systematic reviews and meta-analyses that have examined shared risk factors. Based on searches of Medline, Embase and PsycINFO, inspection of review articles and expert opinion, we first compiled a set of candidate modifiable risk factors associated with autism. Where available, we next collated systematic-reviews (with or without meta-analyses) related to modifiable risk factors associated with both autism and schizophrenia. We identified three modifiable risk factors that have been examined in systematic reviews for both autism and schizophrenia. Advanced paternal age was reported as a risk factor for schizophrenia in a single meta-analysis and as a risk factor in two meta-analyses for autism. With respect to pregnancy and birth complications, for autism one meta-analysis identified maternal diabetes and bleeding during pregnancy as risks factors for autism whilst a meta-analysis of eight studies identified obstetric complications as a risk factor for schizophrenia. Migrant status was identified as a risk factor for both autism and schizophrenia. Two separate meta-analyses were identified for each disorder. Despite distinct clinical phenotypes, the evidence suggests that at least some non-genetic risk factors are shared between these two syndromes. In particular, exposure to drugs, nutritional excesses or deficiencies and infectious agents lend themselves to public health interventions. Studies are now needed to quantify any increase in risk of either autism or schizophrenia that is associated with these modifiable environmental factors. Copyright © 2012 Elsevier Inc

Neuroleptic malignant syndrome (NMS) is an uncommon but potentially serious idiosyncratic response to neuroleptic antipsychotics. It usually affects young males, but the risk has been seen to increase with certain factors including the administration practices of antipsychotic neuroleptics in these individuals. Even though no predictors for NMS are yet known, this article highlights the findings on certain risk factors as seen from a series of fifteen patients who developed NMS. Cautious use of neuroleptics in those at risk, early recognition and institution of immediate management is important.

.3, 3.8]). Having a triptan prescribed by a specialist and using at least 1 other abortive medication with the triptan were associated with a decreased likelihood of triptan discontinuation (0.41, [0.2-0.7] and 0.44 [0.3, 0.8], respectively). As expected, discontinuation was most correlated with lack of efficacy, but other important factors associated with those who had discontinued use included greater migraine-related disability, depression, and the use of opioids for migraine attacks. Compared with patients who had discontinued triptans, current triptan users felt more: educated about their triptan, control over their migraine attacks, and confidence in their prescribing provider. Current triptan users had their triptan prescribed by a specialist and used other abortive medications with their triptan more often compared with patients who had discontinued triptans. Given the cross-sectional nature of this study, we cannot determine if these factors contributed to triptan discontinuation or reflect the impact of such discontinuation. Interventions that address modifiable risk factors for triptan discontinuation may decrease the likelihood of triptan discontinuation and thus improve overall migraine control. Because lack of efficacy was most strongly associated with triptan discontinuation, future research should determine why triptans are effective for some patients but not others. © 2013 American Headache Society.

Arterial lumen narrowing and vascular occlusion is the actual cause of morbidity and mortality in atherosclerotic disease. Collateral artery formation (arteriogenesis) refers to an active remodelling of non-functional vascular anastomoses to functional collateral arteries, capable to bypass the site of obstruction and preserve the tissue that is jeopardized by ischaemia. Hemodynamic forces such as shear stress and wall stress play a pivotal role in collateral artery formation, accompanied by the expression of various cytokines and invasion of circulating leucocytes. Arteriogenesis hence represents an important compensatory mechanism for atherosclerotic vessel occlusion. As arteriogenesis mostly occurs when lumen narrowing by atherosclerotic plaques takes place, presence of cardiovascular risk factors (e.g. hypertension, hypercholesterolaemia and diabetes) is highly likely. Risk factors for atherosclerotic disease affect collateral artery growth directly and indirectly by altering hemodynamic forces or influencing cellular function and proliferation. Adequate collateralization varies significantly among atherosclerotic patients, some profit from the presence of extensive collateral networks, whereas others do not. Cardiovascular risk factors could increase the risk of adverse cardiovascular events in certain patients because of the reduced protection through an alternative vascular network. Likewise, drugs primarily thought to control cardiovascular risk factors might contribute or counteract collateral artery growth. This review summarizes current knowledge on the influence of cardiovascular risk factors and the effects of cardiovascular medication on the development of collateral vessels in experimental and clinical studies.

The role of cardiovascular disease risk factors in the occurrence and progression of cognitive impairment has been the subject of a significant number of publications but has not achieved widespread recognition among many physicians and educated laymen. It is apparent that the active treatment of certain of these cardiovascular disease risk factors is accompanied by a reduced risk for cognitive impairment. Patients with hypertension who are treated experience fewer cardiovascular disease events as well as less cognitive impairment than similar untreated patients. Patients who exercise may present with less cognitive impairment, and obesity may increase the risk for cognitive impairment. Lipid abnormalities and genetic markers are associated with an increased risk for cardiovascular disease and cognitive impairment. Autopsy studies have demonstrated a correlation between elevated levels of cholesterol and amyloid deposition in the brain. Research has demonstrated a relation between atherosclerotic obstruction lesions in the circle of Willis and dementia. Diabetes mellitus is associated with an increased risk for cardiovascular disease and cognitive impairment. A number of nonpharmacologic factors have a role in reducing the risk for cognitive impairment. Antioxidants, fatty acids, and micronutrients may have a role, and diets rich in fruits and vegetables and other dietary approaches may improve the outlook for patients considered at risk for cognitive impairment.

Evidence of variations in schizophrenia incidence rates has been found in genetically homogenous populations, depending on changes within time or space of certain environmental characteristics. The consideration of the impact of environmental risk factors in etiopathogenic studies has put the environment in the forefront of research regarding psychotic illnesses. Various environmental factors such as urbanicity, migration, cannabis, childhood traumas, infectious agents, obstetrical complications and psychosocial factors have been associated with the risk of developing schizophrenia. These risk factors can be biological, physical, psychological as well as social and may operate at different times in an individual's life (fetal period, childhood, adolescence and early adulthood). Whilst some of these factors act on an individual level, others act on a populational level, modulating the individual risk. These factors can have a direct action on the development of schizophrenia, or on the other hand act as markers for directly implicated factors that have not yet been identified. This article summarizes the current knowledge on this subject. An extensive literature search was conducted via the search engine Pubmed. Eight risk factors were selected and developed in the following paper: urbanicity (or living in an urban area), cannabis, migration (and ethnic density), obstetrical complications, seasonality of birth, infectious agents (and inflammatory responses), socio-demographic factors and childhood traumas. For each of these factors, we provide information on the importance of the risk, the vulnerability period, hypotheses made on the possible mechanisms behind the factors and the level of proof the current research offers (good, medium, or insufficient) according to the amount, type, quality and concordance of the studies at hand. Some factors, such as cannabis, are "unique" in their influence on the development of schizophrenia since it labels only one risk factor

Coronary artery disease and stroke predominantly affect older women as opposed to younger women, but the risk factors that contribute to atherosclerotic cardiovascular disease risk often start in young women. Young women with polycystic ovary syndrome (PCOS), with migraine, and who use oral contraceptive pills (OCPs) have short-term increases in thrombotic complications that can result in coronary events or stroke. Attention should be focused on risk reduction in women of all ages. Screening for and discussing diabetes, hypertension, obesity, smoking, migraine, PCOS, and pregnancy complication history and discussing the pros and cons of hormone and statin medications are part of reducing cardiovascular risk for women.

To identify risk factors associated with spontaneous recurrent epistaxis. This was a retrospective cohort study assessing patients in the Marshfield Clinic system diagnosed as having epistaxis between January 1, 1991, and January 1, 2011. There were 461 cases with at least 2 episodes of spontaneous epistaxis within 3 years and 912 controls with only 1 episode in the same time frame. More than 50 potential risk factors were investigated, including demographic features, substance use, nasal anatomical abnormalities, nasal infectious and inflammatory processes, medical comorbidities, medications, and laboratory values. A Cox proportional hazards regression modeling approach was used to calculate hazard ratios of epistaxis recurrence. Traditional risk factors for epistaxis, including nasal perforation, nasal septum deviation, rhinitis, sinusitis, and upper respiratory tract infection, did not increase the risk of recurrence. Significant risk factors for recurrent epistaxis included congestive heart failure, diabetes mellitus, hypertension, and a history of anemia. Warfarin use increased the risk of recurrence, independent of international normalized ratio. Aspirin and clopidogrel were not found to increase the risk of recurrence. Few major adverse cardiovascular events were observed within 30 days of the first epistaxis event. Congestive heart failure is an underappreciated risk factor for recurrent epistaxis. Hypertension and diabetes mellitus may induce atherosclerotic changes in the nasal vessels, making them friable and more at risk for bleeding. Patients with recurrent epistaxis may also be more susceptible to developing anemia. Physicians should promote antiplatelet and antithrombotic medication adherence despite an increased propensity for recurrent epistaxis to prevent major adverse cardiovascular events.

Some risk factors can have impacts on the cost, time, and performance. Results of previous studies indicated that the external conditions are among the factors which give effect to the contractor in the completion of the project. The analysis in the study carried out by considering the conditions of the project in the last 15 years in Aceh province, divided into military conflict phase (2000-2004), post tsunami disaster rehabilitation and reconstruction phase (2005-2009), and post-rehabilitation and reconstruction phase (2010-present). This study intended to analyze the impact of external risk factors, primarily related to the impact on project costs and to investigate the influence of the risk factors and construction phases impacted the project cost. Data was collected by using a questionnaire distributed in 15 large companies qualification contractors in Aceh province. Factors analyzed consisted of socio-political, government policies, natural disasters, and monetary conditions. Data were analyzed using statistical application of severity index to measure the level of risk impact. The analysis results presented the tendency of impact on cost can generally be classified as low. There is only one variable classified as high-impact, variable `fuel price increases', which appear on the military conflict and post tsunami disaster rehabilitation and reconstruction periods. The risk impact on costs from the factors and variables classified with high intensity needs a serious attention, especially when the high level impact is followed by the high frequency of occurrences.

The relative importance of congenital malformations as a cause of death in the first year of life is increasing along with the control of preventable causes of perinatal mortality. To identify risk factors for congenital malformations. Retrospective case-control study of births registered in the database of The Latin American Collaborative Study of Congenital Malformations (ECLAMC), in the period 2001-2010. Birth weight and gestational age were significantly lower in cases than controls, behaving as risk factors and associated with a greater severity of congenital malformations. The risk and severity of congenital malformations increased along with mother's age. Fetal growth retardation, a history of congenital malformations in the family, physical factors and acute illnesses of the mother in the first trimester of pregnancy were also significant risk factors for congenital malformations and their severity. The educational level of the mother was a protective factor for congenital malformations and their severity. Variables previously identified as risk factors for congenital malformations, were significantly related with the occurrence of congenital malformations and their severity.

Hypercoagulable states due either to inherited or acquired thrombotic risk factors are only present in approximately half of cases of DVT, but the causes in the other half, remain unknown. The importance of biological risk factors such as hyperlipidemia, hypofibrinolysis and hemorheological alterations in the pathogenesis of DVT has not been well established. In order to ascertain whether the above mentioned biological factors are associated with DVT and could constitute independent risk factors, we carried out a case-control study in 109 first DVT patients in whom inherited or acquired thrombophilic risk factors had been ruled out and 121 healthy controls age (42+/-15 years) and sex matched. From all the biological variables analyzed (cholesterol, triglycerides, glucose, fibrinogen, erythrocyte aggregation, hematocrit, plasma viscosity and PAI-1) only fibrinogen concentration reached a statistically significant difference on the comparison of means (290+/-73 mg/dl in cases vs 268+/-58 mg/dl in controls, p220 mg/dl, hematocrit >45% and fibrinogen >300 mg/dl was higher in cases than in controls: 38% vs 22%; p30 ng/ml, 37% vs 25% was borderline significant; p=0.055. Multivariate logistic regression analysis showed that cholesterolemia >220 mg/dl and fibrinogen >300 mg/dl constitute independent predictors of venous thrombotic risk. The adjusted OR's were 2.03 (95% CI; 1.12-3.70) for cholesterolemia and 1.94 (95% CI; 1.07-3.55) for fibrinogen. When these two variables combined DVT risk rose about fourfold (3.96; p<0.05). Our results suggest that hypercholesterolemia and hyperfibrinogenemia should be added to the list of known DVT risk factors and we recommend adopting measures to decrease these variables in the population with a high risk of DVT.

Colorectal cancer is the second most common malignancy in the United States, and its incidence rates have sharply increased recently, especially in males. Industrial exposures, both occupational and environmental, are important colorectal cancer risk factors that are generally unrecognized by clinicians. Migration studies have documented that colorectal cancer is strongly associated with environmental risk factors. The causal role of occupational exposures is evidenced by a substantial literature associating specific work practices with increased colorectal cancer risks. Industrially related environmental exposures, including polluted drinking water and ionizing radiation, have also been associated with excess risks. Currently, there is a tendency to attribute colorectal cancer, largely or exclusively, to dietary and other lifestyle factors, thus neglecting these industrially related effects. Concerted efforts are needed to recognize the causal role of industrial risk factors and to encourage government and industry to reduce carcinogenic exposures. Furthermore, cost-effective screening programs for high-risk population groups are critically needed to further reduce deaths from colorectal cancer. 143 references

Atherosclerotic cardiovascular disease (CVD) is one of the leading causes of death and disability worldwide including in developing countries like India. Indians are known to be predisposed to CVD, which occur almost a decade earlier in them. Though these diseases manifest in the middle age and beyond, it is now clear that the roots of CVD lie in childhood and adolescence. Many of the conventional risk factors of CVD such as high blood pressure, dyslipidemia, tobacco use, unhealthy diet and obesity have their beginnings in childhood and then track overtime. It is thus important to screen and identify these risk factors early and treat them to prevent onset of CVD. Similarly community based strategies to prevent onset of these risk factors is imperative to tackle this burgeoning public health crisis especially in countries like ours with limited resources.

Risks are mental models, which allow people to cope with dangerous phenomena (Renn, 2008; Jasanoff, 1998). The term "risk" refers to the likelihood of an adverse effect resulting from an event. The aim of the present study is to identify the psychological factors that are most predictive of risk perception in relation with age, gender, educational level and socio-economical status. Earthquake hazard was considered, because it is an emerging danger for Bucharest. 80% of the laypeople sample are waiting for this event to happen in the next three years. By integrating all the research data, it was attempted to build a risk profile of the investigated population, which could be used by institutions responsible for earthquake risk mitigation situations in Bucharest. This research appealed to the social learning Rotter (1966), auto-effectiveness Bandura (1977; 1983), and anxiety and stress theories. We used psychological variables that measured stress, personal effectiveness and the belief in personal control. The multi-modal risk perception questionnaire was structured on a 49 items sequence. The sample was composed of 1.376 participants recruited on a voluntary basis. The characteristics of risk (like probability and magnitude, time scales) are perceived differently according to psychological factors that play a role also in biases in people's ability to draw inferences from probabilistic information (like cognitive dissonance). Since the 1970's, it has been argued that those who perceive life's events as being beyond their locus of control (external locus of control) are significantly more anxious and less adapted. In this research, strongest associations and significant differences were obtained between sex, age and income categories with Stress vulnerability factor and the External Locus of Control factor. The profile of the low risk perceiver is that of a young, more educated, male individual with a higher self- efficacy level and an internal locus of control.

Currency risk is one of the two components of the total interest rate differential. Hard pegs, such as currency boards, are meant to reduce or even eliminate currency risk, thus, reducing domestic interest rates. This paper investigates the patterns and determinants of the currency risk premium in two currency boards—Argentina and Hong Kong. Despite the presumed rigidity of currency boards, the currency premium is almost always positive and at times very large. Its term structure is usually u...

Full Text Available A major cause of morbidity and mortality in the context of the antiphospholipid syndrome (APS is the occurrence of thrombotic events. Besides the pathogenic roles of antiphospholipid antibodies (aPL, other risk factors and medical conditions, which are conditions for traditional risk of an individual without the APS, can coexist in this patient, raising their risk of developing thrombosis. Therefore, the clinical and laboratory investigation of comorbidities known to increase cardiovascular risk in patients with antiphospholipid antibody syndrome is crucial for the adoption of a more complete and effective treatment. Experimental models and clinical studies show evidence of association between APS and premature formation of atherosclerotic plaques. Atherosclerosis has major traditional risk factors: hypertension, diabetes mellitus, obesity, dyslipidemia, smoking, and sedentary lifestyle that may be implicated in vascular involvement in patients with APS. The influence of nontraditional risk factors as hyperhomocysteinemia, increased lipoprotein a, and anti-oxLDL in the development of thromboembolic events in APS patients has been studied in scientific literature. Metabolic syndrome with all its components also has been recently studied in antiphospholipid syndrome and is associated with arterial events.
The possibility of developing lung cancer (lc) as a consequence of inhaling hot particles from the Chernobyl accident is discussed. The risk from various factors is reviewed in order to assess the rate of contribution for any of them to carcinogenic process. The conclusions are based on data reported by National Centre of Oncology, Sofia (BG). A total of 2873 new cases have been recorded in 1990. The data for the period 1970-1990 show a crude increase for males and tend to stabilization for females. The similar pattern is obtained in other countries and geographic areas with steady rise of lc cases with about 0.5% per year. The contribution of particular risk factor and its interaction with other factors is assessed on the basis of large number of epidemiologic and experimental studies. The risk of cigarette smoking, as the principal cause for lc, is discussed in various aspects - age, duration, possible dropping the habit. The assessment of another risk factor - exposure to relatively high doses of natural radon daughter products - is more complicated. As an occupational hazard in uranium mines radon and its progeny reveals an increase in excess lc incidence. Regarding radon and its daughters as an environmental risk factor in dwellings, no clear positive relationship between exposure and lc incidence has been observed. In this case the assessment for population living in areas with higher concentration of radon products have to rely on data from uranium mines. Non radiation factors as asbestos, ethers, chromates, metallic iron, nickel, beryllium and arsenic, are also considered. The combined effect of all these factors, as well as of pathological cell processes, viruses, malfunctions of immune system, is mentioned as well. The possibility of interpreting the findings from epidemiological studies within the framework of theoretical multistage models of carcinogenic process is pointed out. (author)

Full Text Available Subjects and methods. A total of 917 men from infertile couples with abnormal ejaculate indicators were examined. Their age was 34.1 ± 6.3 years; the infertility period was 4.6 ± 3.9 years. A retrospective analysis of their case histories, clinical examination, questioning to identify risk factors for infertility, and anthropometric measurements of weight and height were made. Weight was rated normal at a body mass index (BMI of ≤ 24.9 kg/m2 ; overweight at 25.0–29.9 kg/m2 , and obesity at ≥ 30 kg/m2 . When identifying infertility risk factors, the investigators kept in mind 24 risk factors at the moment of examination or in the patient histories, which were grouped into 3 clusters: 1 – environmental factors and occupational hazards; 2 – evidence of congenital and acquired abnormalities; 3 – social and quality-of-life factors; this cluster also includes history and examination evidence of tuberculosis, sexually transmitted diseases, and other social diseases, such as hepatitis B and C, or human immunodeficiency infection. Then the men who did not show an exacerbation of somatic diseases, genetic anomalies associated with reproductive disorders, or an exacerbation of social diseases at the moment of examination were selected from the total sample. These were divided into 2 groups: normal weight and obese patients. The frequency of the above mentioned infertility risk factors and additionally the proportion of persons engaged in intellectual or manual labor were calculated in each group.Results and discussion. In the total sample, the frequency of infertility risk factors including occupational hazards and environmental factors was < 20 %; the incidence of congenital and acquired abnormalities was 1–39 %. The highest frequency of risk factors was noted in cluster 3. Among them, alcohol consumption (75 % occupied the first place; next were the rate of sexually transmitted infections (59 %, emotional stress (44 %, and smoking (42

Disasters events are perfect examples of compound events. Disaster risk lies at the intersection of several independent components such as hazard, exposure and vulnerability. Understanding the weight of each component requires extensive standardisation. Here, I show how footprints of past disastrous events were generated using GIS modelling techniques and used for extracting population and economic exposures based on distribution models. Using past event losses, it was possible to identify and quantify a wide range of socio-politico-economic drivers associated with human vulnerability. The analysis was applied to about nine thousand individual past disastrous events covering earthquakes, floods and tropical cyclones. Using a multiple regression analysis on these individual events it was possible to quantify each risk component and assess how vulnerability is influenced by various hazard intensities. The results show that hazard intensity, exposure, poverty, governance as well as other underlying factors (e.g. remoteness) can explain the magnitude of past disasters. Analysis was also performed to highlight the role of future trends in population and climate change and how this may impacts exposure to tropical cyclones in the future. GIS models combined with statistical multiple regression analysis provided a powerful methodology to identify, quantify and model disaster risk taking into account its various components. The same methodology can be applied to various types of risk at local to global scale. This method was applied and developed for the Global Risk Analysis of the Global Assessment Report on Disaster Risk Reduction (GAR). It was first applied on mortality risk in GAR 2009 and GAR 2011. New models ranging from global assets exposure and global flood hazard models were also recently developed to improve the resolution of the risk analysis and applied through CAPRA software to provide probabilistic economic risk assessments such as Average Annual Losses (AAL

METODOLOGÍA: Lactantes de ambos sexos em número de 788, fueron exhaustivamente estudiados en términos de: alimentación, crecimiento, ambiente físico y psicosocial. Se controlaron prospectivamente hasta los 12 meses de edad, momento en que se evaluó el desarrollo mental (MDI y motor (PDI a través de la escala de Bayley. A partir de las variables medidas se identificó 18 factores de riesgo, los que fueron dicotomizados (bajo y alto riesgo. RESULTADOS: Lactancia materna, temperamento del niño, inteligencia materna y estimulación en el hogar se asocian consistentemente con MDI y PDI. Luego de ajustar por covariables, la estimulación en el hogar persiste como factor significativo en la explicación de la variabilidad del MDI y PDI, en tanto que el sexo del niño se consolida como factor condicionante del desarrollo motor. El efecto acumulado de 7 o más factores de riesgo se asocia con una disminución significativa de los puntajes de desarrollo. La combinación de categorías de riesgo de temperamento infantil, inteligencia materna, rol del padre y estimulación en el hogar alcanza mejor predicción del desarrollo infantil que otras combinaciones puestas a prueba en este estudio.

Preeclampsia may present at any gestation but is more commonly encountered in the third trimester. Multiple risk factors have been documented, including: family history, nulliparity, egg donation, diabetes, and obesity. Significant progress has been made in developing tests to predict risk of preeclampsia in pregnancy, but these remain confined to clinical trial settings and center around measuring angiogenic profiles, including placental growth factor or newer tests involving metabolomics. Less progress has been made in developing new treatments and therapeutic targets, and aspirin remains one of the few agents shown to consistently reduce the risk of developing preeclampsia. This review serves to discuss recent advances in risk factor identification, prediction techniques, and management of preeclampsia in antenatal, intrapartum, and postnatal patients.

Full Text Available Follicular lymphoma (FL is an indolent malignancy of germinal center B cells with varied incidence across racial groups and geographic regions. Improvements in the classification of non-Hodgkin lymphoma subtypes provide an opportunity to explore associations between environmental exposures and FL incidence. Our paper found that aspects of Western lifestyle including sedentary lifestyle, obesity, and diets high in meat and milk are associated with an increased risk of FL. Diets rich in fruits and vegetables, polyunsaturated fatty acids, vitamin D, and certain antioxidants are inversely associated with FL risk. A medical history of Sjogren's syndrome, influenza vaccination, and heart disease may be associated with FL incidence. Associations between FL and exposure to pesticides, industrial solvents, hair dyes, and alcohol/tobacco were inconsistent. Genetic risk factors include variants at the 6p21.32 region of the MHC II locus, polymorphisms of the DNA repair gene XRCC3, and UV exposure in individuals with certain polymorphisms of the vitamin D receptor. Increasing our understanding of risk factors for FL must involve integrating epidemiological studies of genetics and exposures to allow for the examination of risk factors and interactions between genes and environment.

We hypothesize that individuals' choices (risk-seeking/risk-aversion) depend on moral values and, in particular, on how subjects evaluate themselves as guilty or as victims of a wrong rather than on the descriptions of the outcomes as given in the options and evaluated accordingly as gains or losses (framing effect). People who evaluate themselves as victims are expected to show a risk-seeking preference (context of innocence). People who evaluate themselves as guilty are expected to show a risk-averse preference (context of guilt). Responses of 232 participants to a decision problem were compared in four different conditions involving two-story formats (innocence/guilt) and two-question-options formats (gain/loss). Regardless of the format of the question options, the story format appears to be an important determinant of individuals' preferences.

A better understanding of risk factors for suicide in general population is crucial for the design of suicide prevention programs. Our objective was to identify personal and family risk factors in suicide attempters. Case-control design. We searched in patients with an acute intoxication, those subjects with and intoxication attributable to suicide attempt. These patients were matched with controls by gender and the date of intoxication. We use a structured questionnaire to identify personal characteristics, family features and network support. Odds ratio (OR) and 95 % confidence interval were obtained. 25 cases and 25 controls were evaluated. The risk factors associated with suicide attempt adjusted by age, were being a student and smoking habits. Family violence background showed OR = 3.8 (IC 95 % = 1.1-13), family disintegration a OR = 8.5 (IC 95 % = 2.1-35), critical events background OR = 8.8 (IC 95 % = 2.1-36), poor self-esteem OR = 8.2 (IC 95 % 2-35), depression OR = 22 (IC 95 % = 3-190), anxiety OR = 9 (IC 95 % = 2-47), family dysfunction OR = 25 (IC 95 % = 4-151). The principal risk factor for suicide attempt was family dysfunction and psychological traits.

Full Text Available Background An estimated 6 of 1,000 children with live births suffer from permanent hearing loss at birth or the neonatal period. At least 90% of cases occur in developing countries. Hearing loss should be diagnosed as early as possible so that intervention can be done before the age of 6 months. Objective To determine risk factors for hearing loss in neonates. Methods We performed a case-control study involving 100 neonates with and without hearing loss who were born at Sanglah Hospital, Denpasar from November 2012 to February 2013. Subjects were consisted of 2 groups, those with hearing loss (case group of 50 subjects and without hearing loss (control group of 50 subjects. The groups were matched for gender and birth weight. We assessed the following risk factors for hearing loss: severe neonatal asphyxia, hyperbilirubinemia, meningitis, history of aminoglycoside therapy, and mechanical ventilation by Chi-square analysis. The results were presented as odds ratio and its corresponding 95% confidence intervals. Results Seventy percent of neonates with hearing loss had history of aminoglycoside therapy. Multivariable analysis revealed that aminoglycoside therapy of 14 days or more was a significant risk factor for hearing loss (OR 2.7; 95%CI 1.1 to 6.8; P=0.040. There were no statistically significant associations between hearing loss and severe asphyxia, hyperbilirubinemia, meningitis, or mechanical ventilation. Conclusion Aminoglycoside therapy for >=14 days was identified as a risk factor for hearing loss in neonates.

To establish the risk factors to hepatitis C virus (HCV) infection, we studied 120 patients divided in 2 groups: A first group of 40 patients with HCV infection, 24 (60%) with past medical history of blood transfusion, 14 (35%) of them also had hemodialysis and 3 Kidney transplant. 10 patients (25%) had mayor surgery without transfusion, 3 had frequent visits to the dentist and 3 month baby whose mother was HCV positive. In 4 patients we found no risk factors. A second group of 80 patients who visit our clinic for the first time, 2 were found positive for HCV (1.6%). 13 of them had blood transfusion, one was HCV+ (OR: 5.5, P = 0.73). 41 had history of mayor surgery, one HCV+ (OR: 0.95, P = 1.000). The risk factors related to HCV infection in our population were blood transfusion, hemodialysis and mayor surgery. The use of EV drugs, tatoos, sexual behavior, interfamiliar or vertical transmission were not risk factor in our population.

Drought is considered one of the most severe and damaging natural hazards in terms of people and sectors affected and associated losses. Drought is a normal and recurrent climatic phenomenon that occurs worldwide, although its spatial and temporal characteristics vary significantly among climates. In the case of Europe, in the last thirty years, the region has suffered several drought events that have caused estimated economic damages over a €100 billion and have affected almost 20% of its territory and population. In recent years, there has been a growing awareness among experts and authorities of the need to shift from a reactive crisis approach to a drought risk management approach, as well as of the importance of designing and implementing policies, strategies and plans at country and river basin levels to deal with drought. The identification of whom and what is vulnerable to drought is a central aspect of drought risk mitigation and planning and several authors agree that societal vulnerability often determines drought risk more than the actual precipitation shortfalls. The final aim of a drought vulnerability assessment is to identify the underlying sources of drought impact, in order to develop policy options that help to enhance coping capacity and therefore to prevent drought impact. This study identifies and maps factors underlying vulnerability to drought across Europe. The identification of factors influencing vulnerability starts from the analysis of past drought impacts in four European socioeconomic sectors. This analysis, along with an extensive literature review, led to the selection of vulnerability factors that are both relevant and adequate for the European context. Adopting the IPCC model, vulnerability factors were grouped to describe exposure, sensitivity and adaptive capacity. The aggregation of these components has resulted in the mapping of vulnerability to drought across Europe at NUTS02 level. Final results have been compared with

Postpartum depression (PPD) is a public health problem with high prevalence in Chile. Many factors are associated with PPD. To analyze the factors associated with the incidence of depressive symptoms (SD) in women with low obstetric risk. Cross-sectional analytical study on a sample of 105 postpartum women with low obstetric risk assessed by the Edinburgh Depression Scale at the eighth week postpartum. A 37% prevalence of depressive symptoms was found. Univariate analysis showed that the perception of family functioning, overcrowding and number of siblings, were significantly associated with postpartum depressive symptoms. A multiple regression model only accepted family functioning as a predictor of depression. Perception of family functioning was the only variable that explained in part the presence of depressive symptoms in women with low obstetric risk.

The death of a parent in a child's life is a significant risk factor for later mental and physical health problems. While much has been written about the surviving parent's functioning and its effects on their bereaved children, little work has been done to look into factors underlying this effect such as how the parent copes. The present study recruited 38 parent-child dyads from a community-based grief support center. Parent and child, independently, completed various measures of emotional functioning, including grief symptoms and coping such as social support and locus of control. The results indicated that parental coping did have an impact on children's grief symptoms. This represents a unique view of adaptation in bereaved children: Parental coping strategies can have an impact on the child, independent of the child's coping strategies. By focusing on parent coping, we have highlighted another possible pathway through which parental functioning affects children's grief.

Context: Non-communicable diseases have emerged as a global health issue. Role of occupation in pathogenesis of non-communicable diseases has not been explored much especially in the hospitality industry. Aims: Objectives of this study include finding risk factor prevalence among hotel workers and studying relationship between occupational group and chronic disease risk factors chiefly high body mass index. Settings and Design: A cross-sectional study was conducted among non-managerial employees from classified hotels in India. Materials and Methods: The study participants self-administered pre-designed pilot-tested questionnaires. Statistical analysis used: The risk factor prevalence rates were expressed as percentages. Chi-square test was used for bi-variate analysis. Overweight was chosen as ‘outcome’ variable of interest and binary multi-logistic regression analysis was used to identify determinants. Results: The prevalence rates of tobacco use, alcohol use, inadequate physical activity and inadequate intake of fruits and vegetables were 32%, 49%, 24% and 92% respectively among hotel employees. Tobacco use was significantly common among those in food preparation and service, alcohol use among those in food service and security and leisure time physical activity among front office workers. More than two-fifths (42.7%) were overweight. Among the hotel workers, those employed in food preparation and security had higher odds of 1.650 (CI: 1.025 – 2.655) and 3.245 (CI: 1.296 – 8.129) respectively of being overweight. Conclusions: Prevalence of chronic disease risk factors is high among hotel workers. Risk of overweight is significantly high in food preparation and security departments and workplace interventions are necessary to address these risks PMID:27390474

Full Text Available Christina A Brook, Louis A SchmidtDepartment of Psychology, Neuroscience and Behaviour, McMaster University, Hamilton, Ontario, CanadaAbstract: Social anxiety disorder (SAD is a debilitating and chronic illness characterized by persistent fear of one or more social or performance situations, with a relatively high lifetime prevalence of 7% to 13% in the general population. Although the last two decades have witnessed enormous growth in the study of biological and dispositional factors underlying SAD, comparatively little attention has been directed towards environmental factors in SAD, even though there has been much ongoing work in the area. In this paper, we provide a recent review and critique of proposed environmental risk factors for SAD, focusing on traditional as well as some understudied and overlooked environmental risk factors: parenting and family environment, adverse life events, cultural and societal factors, and gender roles. We also discuss the need for research design improvements and considerations for future directions.

Whatever the type of injury considered, prevention requires an improvement in health services' awareness of risk factors. The Health Barometer is a general population survey conducted in France since 1992 to contribute to surveillance in this field. The survey's statistical power and the numerous health topics included in the questionnaire provide accurate information for healthcare professionals and decision-makers. The Health Barometer 2010 was a nationwide telephone survey of 9110 persons representative of the 15-85-year-old population. One part of the questionnaire detailed injuries which had occurred during the past year. The numerous variables recorded enabled application of logistic regression models to explore risk factors related to different types of injury by age group. The findings were compared with the Health Barometer 2005 data to search for temporal trends of injury prevalence. The data analysis showed that 10.3% of the 15-85-year-olds reported an injury during the past year. This rate was higher than recorded in 2005; the increase was mainly due to domestic accidents and injuries occurring during recreational activities. Both type of injury and risk factors exhibited age-related variability. Domestic accidents and injuries occurring during recreational activities predominated in the older population and were associated with physical or mental health problems (chronic disease, diability, sleep disorders). For younger people, injuries were related to cannabis use, drunkedness, and insufficient sleep. Risk factors were also depended on type of injury: occupational accident-related injuries were linked with social disadvantage (manual worker population) whereas sports injuries were more common in the socially advantaged population. This survey confirms established knowledge and highlights, at different stages of life, new risk factors that contribute to injuries in France. These findings should be helpful for the development of adapted injury

Full Text Available The article identifies the risks of the economic activity of a factoring company. The identified risks are divided into internal (fraud risk, credit risk, liquidity, nonpayment, staff, supplier's failure to meet the terms of the supply / factoring contract and external (legal, inflation, currency, interest, industry risks, country risk. The cause-effect relationships of the identified risks have been established. The content of information requests of the leading part of the factoring company, as well as the management subsystems (accounting, economic analysis, control and planning, and the direction of information flows between them (to manage the company's internal risks is determined. These proposals contribute to the improvement of accounting and analytical support for risk management of the factoring business, the choice of alternative risk management methods, the impact on their possible consequences, minimizing the negative impact of risks on the financial condition of the company, and establishing the effectiveness of factoring operations under risk.

In the past decades, China has observed rapid urbanization, the nation's urban population reached 50% in 2000, and is still in steady increase. Rapid urbanization in China has an adverse impact on urban hydrological processes, particularly in increasing the urban flood risks and causing serious urban flooding losses. Urban flooding also increases health risks such as causing epidemic disease break out, polluting drinking water and damaging the living environment. In the highly urbanized area, non-engineering measurement is the main way for managing urban flood risk, such as flood risk warning. There is no mature method and pilot study for urban flood risk warning, the purpose of this study is to propose the urban flood risk warning method for the rapidly urbanized Chinese cities. This paper first presented an urban flood forecasting model, which produces urban flood inundation index for urban flood risk warning. The model has 5 modules. The drainage system and grid dividing module divides the whole city terrain into drainage systems according to its first-order river system, and delineates the drainage system into grids based on the spatial structure with irregular gridding technique; the precipitation assimilation module assimilates precipitation for every grids which is used as the model input, which could either be the radar based precipitation estimation or interpolated one from rain gauges; runoff production module classifies the surface into pervious and impervious surface, and employs different methods to calculate the runoff respectively; surface runoff routing module routes the surface runoff and determines the inundation index. The routing on surface grid is calculated according to the two dimensional shallow water unsteady flow algorithm, the routing on land channel and special channel is calculated according to the one dimensional unsteady flow algorithm. This paper then proposed the urban flood risk warning method that is called DPSIR model based

Over the course of decades, the incidence of brachial plexus birth injury (BPBI) has increased despite advances in healthcare which would seem to assist in decreasing the rate. The aim of this study is to identify previously unknown risk factors for BPBI and the risk factors with potential to guide preventative measures. A case control study of 52 mothers who had delivered a child with a BPBI injury and 132 mothers who had delivered without BPBI injury was conducted. Univariate, multivariable and logistic regressions identified risk factors and their combinations. The odds of BPBI were 2.5 times higher when oxytocin was used and 3.7 times higher when tachysystole occurred. The odds of BPBI injury are increased when tachysystole and oxytocin occur during the mother’s labor. Logistic regression identified a higher risk for BPBI when more than three of the following variables (>30 lbs gained during the pregnancy, stage 2 labor >61.5 min, mother’s age >26.4 years, tachysystole, or fetal malpresentation) were present in any combination.

Age-related maculopathy (ARM) is the leading cause of blindness in the elderly. Although beneficial therapeutic strategies have recently begun to emerge, much remains unclear regarding the etiopathogenesis of this disorder. Epidemiologic studies have enhanced our understanding of ARM, but the data, often conflicting, has led to difficulties with drawing firm conclusions with respect to risk for this condition. As a consequence, we saw a need to assimilate the published findings with respect to risk factors for ARM, through a review of the literature appraising results from published cross-sectional studies, prospective cohort studies, case series, and case control studies investigating risk for this condition. Our review shows that, to date, and across a spectrum of epidemiologic study designs, only age, cigarette smoking, and family history of ARM have been consistently demonstrated to represent risk for this condition. In addition, genetic studies have recently implicated many genes in the pathogenesis of age-related maculopathy, including Complement Factor H, PLEKHA 1, and LOC387715/HTRA1, demonstrating that environmental and genetic factors are important for the development of ARM suggesting that gene-environment interaction plays an important role in the pathogenesis of this condition.

Previous studies demonstrate disparities in health and health services including gambling disorders (GD) among ethnic and racial minority groups. In this review, we summarize studies examining the prevalence of GD across different ethnic and racial minorities. We describe the sociodemographic subgroup variations at heightened risk for GD and factors associated with GD in racial and ethnic minority groups including gambling availability, comorbid substance use, psychiatric conditions, stress, acculturation, and differences in cultural values and cognitions. We found that research of GD among minority groups is scant, and the prevalence of GD among these groups is at a magnitude of concern. Racial and ethnic minority status in it of itself is not a risk factor for GD but may be a proxy for underlying potential risk factors. The need for prevention and treatment programs for different cultural group remains unmet.

Full Text Available Intestinal strongyles are the most problematic endoparasites of equids as a result of their wide distribution and the spread of resistant isolates throughout the world. While abundant literature can be found on the extent of anthelmintic resistance across continents, empirical knowledge about associated risk factors is missing. This study brought together results from anthelmintic efficacy testing and risk factor analysis to provide evidence-based guidelines in the field. It involved 688 horses from 39 French horse farms and riding schools to both estimate Faecal Egg Count Reduction (FECR after anthelmintic treatment and to interview farm and riding school managers about their practices. Risk factors associated with reduced anthelmintic efficacy in equine strongyles were estimated across drugs using a marginal modelling approach. Results demonstrated ivermectin efficacy (96.3% ± 14.5% FECR, the inefficacy of fenbendazole (42.8% ± 33.4% FECR and an intermediate profile for pyrantel (90.3% ± 19.6% FECR. Risk factor analysis provided support to advocate for FEC-based treatment regimens combined with individual anthelmintic dosage and the enforcement of tighter biosecurity around horse introduction. The combination of these measures resulted in a decreased risk of drug resistance (relative risk of 0.57, p = 0.02. Premises falling under this typology also relied more on their veterinarians suggesting practitionners play an important role in the sustainability of anthelmintic usage. Similarly, drug resistance risk was halved in premises with frequent pasture rotation and with stocking rate below five horses/ha (relative risk of 0.53, p < 0.01. This is the first empirical risk factor analysis for anthelmintic resistance in equids. Our findings should guide the implementation of more sustained strongyle management in the field.

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.

Breast cancer is the most common malignancy among women in the Western society. Over the past decades it has become apparent that breast cancer incidence rates are increasing steadily, whereas the mortality rates for breast cancer have remained relatively constant. Information through the media on this rising number of cases has increased breast health awareness but has also introduced anxiety in the female population. This combination of factors has made the need for prevention of breast cancer an urgent matter. Breast cancer does not seem to be a single disease entity. A specific etiologic factor may therefore have more influence on one form may therefore have more influence on one form of breast cancer than another. So far though, as shown in their summary of current knowledge on established and dubious risk factors, no risk factors have been identified that can explain a major part of the incidence. Efforts to identify other ways for primary prevention have also been discouraging, even though breast cancer is one of the most investigated tumours world-wide. Thus, at this point i time, the most important strategy to reduce breast cancer mortality is early detection through individual counselling and organised breast screening programs. The recent isolation of breast cancer susceptibility genes may introduce new ways to reduce the risk of breast cancer in a small subset of women

A prior history of delivery complicated by shoulder dystocia confers a 6-fold to nearly 30-fold increased risk of shoulder dystocia recurrence in a subsequent vaginal delivery, with most reported rates between 12% and 17%. Whereas prevention of shoulder dystocia in the general population is neither feasible nor cost-effective, directing intervention efforts at the particular subgroup of women with a prior history of shoulder dystocia has merit. Potentially modifiable risk factors and individualized management strategies that may reduce shoulder dystocia recurrence and its associated significant morbidities are reviewed.

Full Text Available Studies on young people who live in restricted areas under liberty deprivation are relevant to improve educational measures and put them into effect, once education is a way of achieving a positive reintegration of young institutionalized people into society. This paper starts describing and discussing national articles, selected from SciELO and LILACS databases, focusing on education inside restricted areas with liberty deprivation, specifically addressing young population. Then, the paper discusses child abuse, learning disabilities and behavior problems, all issues related to risk factors that may lead to children and adolescent’s conduct impairment, being, many times, the cause and/or reinforcement of violent behavior and delinquency. This research found that there is a considerable shortage of articles on education of young people living under liberty deprivation in Brazil. The analyzed national publications reflect, as well as authors from other countries, that many young offenders have experienced abuse and/or parental neglect during their childhood, have exhibited behavior problems and/or learning disabilities. Estudos sobre os jovens em espaços de restrição e privação de liberdade são relevantes para que medidas educacionais sejam efetivadas e aprimoradas, sendo que a educação é um meio de acesso à reintegração do jovem institucionalizado na sociedade de forma positiva. O presente trabalho primeiramente descreve e discute, através de uma busca nas bases de dados SciELO e LILACS, artigos nacionais produzidos no campo da educação em espaços de restrição e privação de liberdade, especificamente referente à população jovem. Em um segundo momento o artigo discute sobre maus-tratos infantis, dificuldades de aprendizagem e problemas de comportamento, os quais são temas relacionados a fatores de risco que podem levar ao comprometimento da conduta da criança e do adolescente, sendo, por vezes, causadores e/ou refor

Full Text Available As for the research into this subject, we find, therefore, that one of the most important indicators that quantify the international competitiveness is the exchange rate, together with other fundamental macroeconomic variables such as the size of the potential GDP, the equilibrium real exchange rate, gives a certain insight into the functioning of the fundamental macroeconomic mechanisms and their regulation. Commercial and financial operations imply relationships between partners from different currency countries or areas that involve conversion operations, of replacement of a currency to another. Exchange rate fluctuations of one currency create currency risk, to the extent that it is used to carry out international transactions. These operations are subjected to currency risk as exchange rates change frequently from one period to another and, on the other hand, speculations in the forex market influence the exchange rate by the interventions of those who perform them.

In a context of concurrence and emergence of energy markets, the production of electricity is affected by the new sources of risks which are the price variations on the energy markets. These new sources of risks generate a new risk: the market risk. In this research, the author explores the possibility of introducing constraints, expressed by measurements of risk, into the process of optimization of electricity production when financial contracts are signed on the energy market. The author makes the distinction between the engineering approach (taking the risk into account by risk measurements) and the economist approach (taking the risk into account by utility functions). After an overview of these both approaches in a static framework, he gives an economical formulation (a Maccheroni type one) for a static optimization problem under a risk constraint when the risk measurement is written under the form of an expected infimum like the variance, the 'conditional value at risk', and so on. The obtained results are then extended to a dynamic optimization framework under risk constraints. A numerical application of this approach is presented to solve a problem of electricity production management under a constraint of 'conditional value at risk' on a middle term

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease. It is typically fatal within 2–5 years of symptom onset. The incidence of ALS is largely uniform across most parts of the world, but an increasing ALS incidence during the last decades has been suggested. Although recent genetic studies have substantially improved our understanding of the causes of ALS, especially familial ALS, an important role of non-genetic factors in ALS is recognized and needs further study. In this review, we briefly discuss several major genetic contributors to ALS identified to date, followed by a more focused discussion on the most commonly examined non-genetic risk factors for ALS. We first review factors related to lifestyle choices, including smoking, intake of antioxidants, physical fitness, body mass index, and physical exercise, followed by factors related to occupational and environmental exposures, including electromagnetic fields, metals, pesticides, β-methylamino-L-alanine, and viral infection. Potential links between ALS and other medical conditions, including head trauma, metabolic diseases, cancer, and inflammatory diseases, are also discussed. Finally, we outline several future directions aiming to more efficiently examine the role of non-genetic risk factors in ALS. PMID:25709501

The aim of this review was to describe the current evidence-based knowledge of the epidemiology, prevalence, incidence, risk factors and genetic associations of drug allergy. Articles published between 1966 and 2010 were identified in MEDLINE using the key words adult, adverse drug reaction reporting systems, age factors, anaphylactoid, anaphylaxis, anaesthetics, antibiotics, child, drug allergy, drug eruptions, ethnic groups, hypersensitivity, neuromuscular depolarizing agents, neuromuscular nondepolarizing agents, sex factors, Stevens Johnson syndrome and toxic epidermal necrolysis. Additional studies were identified from article reference lists. Relevant, peer-reviewed original research articles, case series and reviews were considered for review. Current epidemiological studies on adverse drug reactions (ADRs) have used different definitions for ADR-related terminology, often do not differentiate immunologically and non-immunologically mediated drug hypersensitivity, study different study populations (different ethnicities, inpatients or outpatients, adults or children), utilize different methodologies (spontaneous vs. non-spontaneous reporting, cohort vs. case-control studies), different methods of assessing drug imputability and different methods of data analyses. Potentially life-threatening severe cutaneous adverse reactions (SCAR) are associated with a high risk of morbidity and mortality. HLA associations for SCAR associated with allopurinol, carbamazepine and abacavir have been reported with the potential for clinical use in screening prior to prescription. Identification of risk factors for drug allergy and appropriate genetic screening of at-risk ethnic groups may improve the outcomes of drug-specific SCAR. Research and collaboration are necessary for the generation of clinically-relevant, translational pharmacoepidemiological and pharmacogenomic knowledge, and success of health outcomes research and policies on drug allergies. © 2011 The Authors

In several regions, but especially in semi-arid areas, raising frequency, duration and intensity of drought events, mainly driven by climate change dynamics, are expected to dramatically reduce the current stocks of freshwater resources, limiting crop development and yield especially where agriculture largely depends on irrigation. The achievement of an affordable and sustainable equilibrium between available water resources and irrigation demand is essentially related to the planning and implementation of evidence-based adaptation strategies and actions. The present study proposed a state-of-the art conceptual framework and computational methodology to assess the potential water scarcity risk, due to changes in climate trends and variability, on irrigated croplands. The model has been tested over the irrigated agriculture of Puglia Region, a semi-arid territory with the largest agricultural production in Southern Italy. The methodology, based on the Regional Risk Assessment (RRA) approach, has been applied within a scenario-based hazard framework. Regional climate projections, under alternative greenhouse gas concentration scenarios (RCP4.5 and RCP8.5) and for two different timeframes, 2021-2050 and 2041-2070 compared to the baseline 1976-2005 period, have been used to drive hydrological simulations of river inflow to the most important reservoirs serving irrigation purposes in Puglia. The novelty of the proposed RRA-based approach does not simply rely on the concept of risk as combination of hazard, exposure and vulnerability, but rather elaborates detailed (scientific and conceptual) framing and computational description of these factors, to produce risk spatial pattern maps and related statistics distinguishing the most critical areas (risk hot spots).. The application supported the identification of the most affected areas (i.e. Capitanata Reclamation Consortia under RCP8.5 2041-2070 scenario), crops (fruit trees and vineyards), and, finally, the vulnerability

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.

Objective This study aimed to investigate the relationship between maternal hypertensive disease and other risk factors and the neonatal development of necrotizing enterocolitis (NEC). Methods This was a retrospective case control study of infants with NEC from 2008 to 2012. The primary exposure of interest was maternal hypertensive disease, which has been hypothesized to put infants at risk for NEC. Other variables collected included demographics, pregnancy complications, medications, and neonatal hospital course. Data was abstracted from medical records. Results 28 cases of singleton neonates with NEC and 81 matched controls were identified and analyzed. There was no significant difference in the primary outcome. Fetuses with an antenatal diagnosis of growth restriction were more likely to develop NEC (p=0.008). Infants with NEC had lower median birth weight than infants without NEC (p=0.009). Infants with NEC had more late-onset sepsis (p=0.01) and mortality before discharge (p=0.001). Conclusions The factors identified by this case-control study that increased the risk of neonatal NEC included intrauterine growth restriction and lower neonatal birth weight. The primary exposure, hypertensive disease, did not show a significantly increased risk of neonatal NEC, however there was a nearly two-fold difference observed. Our study was underpowered to detect the observed difference. PMID:25162307

Parkinson's disease (PD) is a neurodegenerative disorder characterized by tremor, rigidity, bradykinesia, gait disturbance, and postural instability. Patients with PD suffer frequent falls, yet little research has been done to identify risks specific to PD patients. The objective of this study was to identify the risk factors associated with falls for PD patients through the collection of demographic, environmental, and medical information as well as fall diaries completed during a 3-month period. Patients with a diagnosis of idiopathic PD, with and without falls, were included in the study provided they could stand and walk and had no other condition that could predispose them to falls. Of the 118 participants, 59% reported one or more falls. A total of 237 falls were reported. Duration and severity of PD symptoms, particularly freezing, involuntary movements, and walking and postural difficulties, were significantly associated with an increased risk of falls. Other factors associated with falls were postural hypotension and daily intake of alcohol. Forty percent of falls resulted in injury, but serious injury was rare. The findings have implications for reducing the risk of falls through patient education.

Non-specific spinal pain can occur at all ages and current evidence suggests that pediatric non-specific spinal pain is predictive for adult spinal conditions. A 5-year long, prospective cohort study was conducted to identify the lifestyle and environmental factors leading to non-specific spinal pain in childhood. Data were collected from school children aged 7-16 years, who were randomly selected from three different geographic regions in Hungary. The risk factors were measured with a newly developed patient-reported questionnaire (PRQ). The quality of the instrument was assessed by the reliability with the test-retest method. Test (N = 952) and validity (N = 897) datasets were randomly formed. Risk factors were identified with uni- and multivariate logistic regression models and the predictive performance of the final model was evaluated using the receiver operating characteristic (ROC) method. The final model was built up by seven risk factors for spinal pain for days; age > 12 years, learning or watching TV for more than 2 h/day, uncomfortable school-desk, sleeping problems, general discomfort and positive familiar medical history (χ 2 = 101.07; df = 8; p < 0.001). The probabilistic performance was confirmed with ROC analysis on the test and validation cohorts (AUC = 0.76; 0.71). A simplified risk scoring system showed increasing possibility for non-specific spinal pain depending on the number of the identified risk factors (χ 2 = 65.0; df = 4; p < 0.001). Seven significant risk factors of non-specific spinal pain in childhood were identified using the new, easy to use and reliable PRQ which makes it possible to stratify the children according to their individual risk.

PURPOSE: To determine the incidence and risk factors of late corneal graft rejection after penetrating keratoplasty (PKP. METHODS: Records of all patients who had undergone PKP from 2002 to 2004 without immunosuppressive therapy other than systemic steroids and with at least one year of follow up were reviewed. The role of possible risk factors such as demographic factors, other host factors, donor factors, indications for PKP as well as type of rejection were evaluated. RESULTS: During the study period, 295 PKPs were performed on 286 patients (176 male, 110 female. Mean age at the time of keratoplasty was 38±20 (range, 40 days to 90 years and mean follow up period was 20±10 (range 12-43 months. Graft rejection occurred in 94 eyes (31.8% at an average of 7.3±6 months (range, 20 days to 39 months after PKP. The most common type of rejection was endothelial (20.7%. Corneal vascularization, regrafting, anterior synechiae, irritating sutures, active inflammation, additional anterior segment procedures, history of trauma, uncontrolled glaucoma, prior graft rejection, recurrence of herpetic infection and eccentric grafting increased the rate of rejection. Patient age, donor size and bilateral transplantation had no significant influence on graft rejection. CONCLUSION: Significant risk factors for corneal graft rejection include

This study explored how different forms of reward-based decision-making are associated with pathological gambling (PG) among abstinent individuals with prior dependence on different classes of drugs. Participants had lifetime histories of either "pure" heroin dependence ( n = 64), "pure" amphetamine dependence ( n = 51), or polysubstance dependence ( n = 89), or had no history of substance dependence ( n = 133). Decision-making was assessed via two neurocognitive tasks: (1) the Iowa Gambling Task (IGT), a measure of decision-making under ambiguity (i.e., uncertain risk contingencies); and (2) the Cambridge Gambling task (CGT), a measure of decision-making under risk (i.e., explicit risk contingencies). The main effects of neurocognitive performance and drug class on PG (defined as ≥3 DSM-IV PG symptoms) as well as their interactional effects were assessed via multiple linear regression. Two CGT indices of decision-making under risk demonstrated positive main effects on PG. Interaction effects indicated that the effects of decision-making under risk on PG were largely consistent across participant groups. Notably, a linear relationship between greater CGT Risk-Taking and PG symptoms was not observed among amphetamine users, whereas IGT performance was selectively and positively associated with PG in polysubstance users. Overall, results indicate that reward-based decision-making under risk may represent a risk factor for PG across substance users, with some variations in these relationships influenced by specific class of substance of abuse.

While multiple studies have demonstrated that modification of atherosclerotic cardiovascular risk factors (CVRFs significantly reduces morbidity and mortality rates, clinical control of CVDs and CVRFs remains poor. By 2010, the American Heart Association seeks to reduce coronary heart disease, stroke, and risk by 25%. To meet this goal, clinical practitioners must establish new treatment paradigms for CVDs and CVRFs. This paper discusses one such treatment model – a comprehensive atherosclerosis program run by physician extenders (under physician supervision, which incorporates evidence-based CVD and CVRF interventions to achieve treatment goals.Keywords: atherosclerosis, cardiovascular risk factors, prevention, modification

The prevalence of latex sensitisation varies according to the population studied. There are various risk factors that increase latex sensitisation, such as genetic risk, atopy, and multiple surgeries. To characterise patients referred to an Immunology Unit with suspected latex allergy, and to analyse their clinical features and risk factors. A retrospective, descriptive study was conducted on children suspected of latex allergy. Their medical records were reviewed in order to assess symptoms with contact or exposure to latex materials. Known risk factors to latex sensitisation, such as pathologies requiring repeated surgery (spina bifida, myelomeningocele, scoliosis and nephro-urological alterations), atopy (rhinitis, asthma, atopic dermatitis) were investigated. A prick test and/or specific IgE to latex were also performed. A multivariate logistic regression model was performed to find associations between symptoms triggered by exposure to latex with underlying diseases and other risk conditions. A total of 106 patients were enrolled in the study, of whom 50 were evaluable. At diagnosis 96% of patients were older than five years. Most of the risk factors described were observable in these patients, such as multiple surgeries, neurological and nephro-urological malformations, surgery before one year-old, and repeated bladder catheterisation. After latex exposure, mucous cutaneous manifestations were the most common (52%), followed by respiratory symptoms (36%). All patients were sensitised and allergic to latex. Latex allergy is a significant problem in children with risk factors. The results shown in this study raise important challenges for preventive measures and awareness.

Full Text Available The article considers the most significant risk factors for the development of childhood under the contemporary conditions of the Russian family functioning. The specifics of the Russian society is determined by the implementation of fundamental social and economic reforms in the country in the last decades. The article provides a comprehensive analysis of key risk factors and defines possible negative consequences of their impact on the children personal development. Based on statistics and international legislation the article examines the issue of children protection from various forms of domestic violence. The demographic risk factors are considered from the perspective of raising a child in a one-child family, in the situation of childbirth out of wedlock and after the divorce, or the child’s health problems and the lack of conditions for its improvement. The author believes that the low quality of life is an important factor for the childhood risks development for it limits cognitive and physiological needs of the child. The article also points to the connection of the parents’ authority with their professional occupation and unemployment. Thus, the author comes to the following conclusions: childhood development is inevitably linked with the acquisition of life experience of overcoming risk situations; the family strategy to protection the child from all dangerous contacts is pedagogically unjustified and hinders the socialization process. In order to achieve positive results in overcoming the childhood risks, it is necessary to increase the educational competence of parents in the prevention of possible risks. The task of the family is not to isolate the child from the risks, but to teach the child to overcome them.

The objective of this study is to determine risk factors for fatigue among airline pilots, taking into account person-, work-, health-, sleep-, and lifestyle-related characteristics. The study population consisted of 502 pilots who participated in the MORE Energy study. Included risk factors were either measured through an online questionnaire or provided by the company. The outcome of this study, fatigue, was assessed using the Checklist Individual Strength (CIS), and was defined as scoring more than 76 points on this questionnaire. The association of the risk factors with fatigue was determined using univariate and multivariate logistic regression analyses. Of the participating pilots, 29.5 % scored more than 76 points on the CIS and were classified as being fatigued. The fully adjusted regression model showed that person-, work-, health-, and lifestyle-related characteristics were associated with fatigue. Pilots who were aged 31 to 40 (OR 3.36, 95 % CI 1.32-8.53) or 41 to 50 (OR 4.19, 95 % CI 1.40-12.47), an evening type (OR 2.40, 95 % CI 1.38-4.16), scored higher on work-life balance disturbance (OR 1.22, 95 % CI 1.10-1.36), scored higher on need for recovery (OR 1.02, 95 % CI 1.01-1.04), scored lower on general health perception (OR 0.31, 95 % CI 0.20-0.47), were less physically active (OR 0.77, 95 % CI 0.66-0.89), and had a moderate alcohol consumption (OR 3.88, 95 % CI 1.21-12.43), were at higher risk for fatigue. Higher age, being an evening type, disturbance of the work-life balance, more need for recovery, a lower perceived health, less physical activity, and moderate alcohol consumption were shown to be risk factors for fatigue. Further longitudinal research is needed to elucidate the direction of the associations found and to evaluate the effects of possible countermeasures in airline pilots.

Shoulder dystocia remains an unpredictable obstetric emergency, striking fear in the hearts of obstetricians both novice and experienced. While outcomes that lead to permanent injury are rare, almost all obstetricians with enough years of practice have participated in a birth with a severe shoulder dystocia and are at least aware of cases that have resulted in significant neurologic injury or even neonatal death. This is despite many years of research trying to understand the risk factors associated with it, all in an attempt primarily to characterize when the risk is high enough to avoid vaginal delivery altogether and prevent a shoulder dystocia, whose attendant morbidities are estimated to be at a rate as high as 16-48%. The study of shoulder dystocia remains challenging due to its generally retrospective nature, as well as dependence on proper identification and documentation. As a result, the prediction of shoulder dystocia remains elusive, and the cost of trying to prevent one by performing a cesarean delivery remains high. While ultimately it is the injury that is the key concern, rather than the shoulder dystocia itself, it is in the presence of an identified shoulder dystocia that occurrence of injury is most common. The majority of shoulder dystocia cases occur without major risk factors. Moreover, even the best antenatal predictors have a low positive predictive value. Shoulder dystocia therefore cannot be reliably predicted, and the only preventative measure is cesarean delivery. Copyright © 2014 Elsevier Inc. All rights reserved.

The objectives of the study were (1) to assess prevalence of social withdrawal behaviour in infants aged 12 months included in the French Perinatal Risk Factor Study Eden; (2) To study the correlation between relational withdrawal and several perinatal and parental factors assessed in the EDEN study. A longitudinal study using the ADBB scale was conducted within the Eden Cohort in the year 2008. 1,586 infants were included in the study. Fourteen percent of the children who had an ADBB assessment had a score at 5 and over on the ADBB, a scale designed to assess social withdrawal behaviour at age 0-24 months. Social withdrawal at 12 months was associated with low birth weight, low gestational age and with intra uterine growth retardation. Social withdrawal was independently associated with several maternal and paternal risk factors. The level of social withdrawal behaviour increased with a score of maternal difficulties. This study on a large longitudinally followed volunteer sample demonstrate a clear association of social withdrawal behaviour at age one with low birth weight and preterm birth, possibly mediated by parental vulnerabilities. Social withdrawal behaviour seems to be an important alarm signal to detect early on particularly in premature and small for date babies. © Springer-Verlag 2012

Multivariate statistical analysis is indispensable to assess the associations and interactions between different factors and the risk of periodontitis. Among others, regression analysis is a statistical technique widely used in healthcare to investigate and model the relationship between variables. In our work we study the impact of socio-demographic, medical and behavioral factors on periodontal health. Using regression, linear and logistic models, we can assess the relevance, as risk factors for periodontitis disease, of the following independent variables (IVs): Age, Gender, Diabetic Status, Education, Smoking status and Plaque Index. The multiple linear regression analysis model was built to evaluate the influence of IVs on mean Attachment Loss (AL). Thus, the regression coefficients along with respective p-values will be obtained as well as the respective p-values from the significance tests. The classification of a case (individual) adopted in the logistic model was the extent of the destruction of periodontal tissues defined by an Attachment Loss greater than or equal to 4 mm in 25% (AL≥4mm/≥25%) of sites surveyed. The association measures include the Odds Ratios together with the correspondent 95% confidence intervals.

To investigate the risk factors for anorexia in children, and to reduce the prevalence of anorexia in children. A questionnaire survey and a case-control study were used to collect the general information of 150 children with anorexia (case group) and 150 normal children (control group). Univariate analysis and multivariate logistic stepwise regression analysis were performed to identify the risk factors for anorexia in children. The results of the univariate analysis showed significant differences between the case and control groups in the age in months when supplementary food were added, feeding pattern, whether they liked meat, vegetables and salty food, whether they often took snacks and beverages, whether they liked to play while eating, and whether their parents asked them to eat food on time (Panorexia in children. Liking of meat (OR=0.093) and vegetables (OR=0.272) and eating on time required by parents (OR=0.079) were protective factors against anorexia in children. Timely addition of supplementary food, a proper diet, and development of children's proper eating and living habits can reduce the incidence of anorexia in children.

Full Text Available Background/Aim. World Health Organization (WHO in its plan for health policy until the year 2010, has taken reduction of risk factors of suicide as its 12th aim. Because of the fact that the problem of suicide is also significant health problem in our society, the aim of this study was to examine the influence of life period as a risk factor for suicide in the area of the town of Kragujevac. Methods. In total 211 persons, both sexes, aged between 17 and 91 years, from the area of the town of Kragujevac, who had been committed a suicide during the period from 1996 to 2005, were included in a retrospective study. This study included the analysis of: conditions prior to suicide, locations of suicide, motives for suicide, the ways of committing suicide. For statistical analysis χ2 test and univariante regression model were used. Results. Average rate of suicide, in analyzed period, moved from 8.7 to 27 with a mean value of 14.6± 6.9. Suicide rates were the lowest in the age group from 15 to 24 years and the highest in the age group above 65 years (p < 0.05. Among the presuicidal conditions, within any age groups the presence of mental disease dominated as a factor for suicide, but within the oldest one in which organic diseases prevailed as a factor for suicide (p < 0.05. Statistically significant fact is that a house (flat was the main location for committing suicide in any age groups. Motives for suicide were significantly different within the groups and they were mostly unknown. Committing suicide by hanging was the most frequent way of suicide among any age groups. Univariant regression analysis failed to show any impact of age on the analyzed factors. Conclusion. Because of the fact that an average rate of suicide in elderly increases it is obligatory to primarily determine risk factors for suicide among people more than 65 years of age. Physicians should play the most important role in that.

Research has identified a number of risk factors for road traffic accidents. Some of these require education of drivers and a first step in this process is to assess perceptions of these risk factors to determine the current level of awareness. An online survey examined risk perception with the focus being on driver behavior, risk taking and fatigue. The results showed that drivers’ perceptions of the risk from being fatigued was lower than the perceived risk from the other factors.

This study aims to define the characteristics of adolescents who have engaged in self-harm behavior and ascertain the risk factors. From January 2013 to January 2014, 4,176 adolescents from senior middle schools in Linyi, China, were administered four questionnaire surveys to ascertain the following: incidence of self-harm behavior regarding the frequency of different self-harm behaviors by group (never/one to five times/greater than five times in the last 6 months) and then comparing the self-harm behavior of the different subgroups; symptom self-check, comparing the differences between the adolescents with self-harm behavior and without in nine subscales (somatization, obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, hostility, fear, paranoid, and psychosis); Adolescent Self-Rating Life Events Check List scores; and Egna Minnenav Barndoms Uppfostran (EMBU) scores. Multivariate logistic regression analysis was used to determine the risk factors of self-harm in adolescents. The incidence of adolescent self-harm was 27.60%; the occurrence of adolescent self-harm was closely related to their mental health status, stressful life events, and EMBU. Being female, an urban student, or an only child; having poor school performance or experiences of stressful life events, harsh parenting styles, or excessive interference; and poor mental health were the risk factors for adolescent self-harm. The incidence of adolescent self-harm was high, and their mental health status, stressful life events, and EMBU affected the occurrence of adolescent self-harm, which is an issue that needs greater attention. © 2016 John Wiley & Sons Australia, Ltd.

Socio-economic status (SES) is strongly correlated with hypertension. But SES has several components, including income and correlations in cross-sectional data need not imply SES is a risk factor. This study investigates whether wages-the largest category within income-are risk factors. We analysed longitudinal, nationally representative US data from four waves (1999, 2001, 2003 and 2005) of the Panel Study of Income Dynamics. The overall sample was restricted to employed persons age 25-65 years, n = 17 295. Separate subsamples were constructed of persons within two age groups (25-44 and 45-65 years) and genders. Hypertension incidence was self-reported based on physician diagnosis. Our study was prospective since data from three base years (1999, 2001, 2003) were used to predict newly diagnosed hypertension for three subsequent years (2001, 2003, 2005). In separate analyses, data from the first base year were used to predict time-to-reporting hypertension. Logistic regressions with random effects and Cox proportional hazards regressions were run. Negative and strongly statistically significant correlations between wages and hypertension were found both in logistic and Cox regressions, especially for subsamples containing the younger age group (25-44 years) and women. Correlations were stronger when three health variables-obesity, subjective measures of health and number of co-morbidities-were excluded from regressions. Doubling the wage was associated with 25-30% lower chances of hypertension for persons aged 25-44 years. The strongest evidence for low wages being risk factors for hypertension among working people were for women and persons aged 25-44 years.

It is commonly believed that pregnancy is a time of good mental health. However it has been observed, until recently, that many pregnant women, above all in post partum period, manifest depressive symptoms like sadness, social withdrawal and lack of motivation. The consequences are enormous, for mother mental health and for the psychical development of the baby. It becomes therefore necessary to screening and to precociously intervene on these pathological conditions and thanks also to the suitable knowledge of the risk factors for the potential development of depression post partum.

Dentists are at the forefront for screening oral cancer. In addition to the well known carcinogenic potential of tobacco and alcohol, betel nut chewing and human papilloma virus are important risk factors in the development of oral cancer. To aid in screening and decreasing morbidity and mortality from oral cancer, a variety of techniques have been developed. These techniques show promise but they require additional investigations to determine their usefulness in oral cancer detection. Dentists need to be well educated and vigilant when dealing with all patients they encounter. Early detection, diagnosis and treatment are critical for the effective management of oral cancers.

To establish a grading system that helps identify high-risk individuals who may experience corneal ectasia after LASIK. Retrospective, comparative, interventional case series. One hundred forty-eight consecutive patients (148 eyes) were included in this study. Thirty-seven patients who underwent LASIK at other refractive centers experienced corneal ectasia in 1 eye after LASIK. One hundred eleven eyes of 111 patients who underwent successful LASIK during the same period were age and gender matched and served as controls. All patients underwent preoperative and postoperative topographic analysis of the cornea. The follow-up period in both groups of patients ranged from 2 to 5 years, with a mean follow-up of 3.6 years. All patients underwent LASIK for myopia (spherical equivalent, -4.00 to -8.00 diopters). Corneal keratometry, oblique cylinder, pachymetry, posterior surface elevation, difference between the inferior and superior corneal diopteric power, and posterior best sphere fit (BSF) over anterior BSF were given a grade of 1 to 3 each. An ectasia grading system was established, and the cumulative risk score was assessed. Patients who had a grade of 7 or less showed no evidence of corneal ectasia, whereas 16 (59%) of 27 patients who had a grade of 8 to 12 had corneal ectasia. Twenty-one (100%) of 21 patients with a grade of more than 12 had corneal ectasia after LASIK (P<0.0001). A risk score may help in the prediction of patients who are at risk of experiencing corneal ectasia after LASIK. A prospective clinical study is needed to assess the validity of these risk factors.
Full Text Available Background and aims :Prevalence of musculoskeletal disorders (MSDs is high among office workers. Long time seated posture, working with computer, repetitive movements and inappropriate environmental conditions may have causal effects in these disorders. High prevalence rate of MSDs makes ergonomics assessment and working conditions improvement necessary. Designing an assessment checklist and calculating ergonomics indices can be useful in this evaluation. This study was conducted with the objectives of determination of prevalence rate, ergonomics assessment of working conditions and determination of factors associated with MSDs among office workers. Methods:In this study 400 randomly selected office workers participated. Nordic musculoskeletal disorders questionnaire was applied to determine prevalence rate of MSDs. Working conditions were assessed by the designed ergonomics checklist and ergonomic risk factors were identified. Data were analyzed using statistical tests including t-test, Chi-square and test of proportion by SPSS software (Version 12.0. Results:The highest prevalence rates of MSDs were reported in lower back and neck regions (49% and 47%, respectively. Statistical analysis revealed that there were significant association between occurrence of MSDs and calculated ergonomics indices (P<0.05. The mean of ergonomics index among those suffered from MSDs were less than other healthy workers indicating inappropriate ergonomics conditions. Calculation of OR also revealed that ergonomics conditions was associated with MSDs occurrence among workers (P<0.05. Totally, 53.3% of the office workers studied had poor working conditions. Awkward working posture and inappropriate workstation design were recognized as the main risk factors in the office workplace. Conclusion:Most ergonomics problems were originated from bad postures and inappropriate design of workstation. Any interventional program for working conditions improvement should

Risk-based water resources planning is based on the premise that water managers should invest up to the point where the marginal benefit of risk reduction equals the marginal cost of achieving that benefit. However, this cost-benefit approach may not guarantee robustness under uncertain future conditions, for instance under climatic changes. In this paper, we expand risk-based decision analysis to explore possible ways of enhancing robustness in engineered water resources systems under different risk attitudes. Risk is measured as the expected annual cost of water use restrictions, while robustness is interpreted in the decision-theoretic sense as the ability of a water resource system to maintain performance—expressed as a tolerable risk of water use restrictions—under a wide range of possible future conditions. Linking risk attitudes with robustness allows stakeholders to explicitly trade-off incremental increases in robustness with investment costs for a given level of risk. We illustrate the framework through a case study of London's water supply system using state-of-the -art regional climate simulations to inform the estimation of risk and robustness.

Full Text Available Low birth weight (LBW remains to be a leading cause of neonatal death and a major contributor to infant and under-five mortality. Its prevalence has not declined in the last decade in sub-Saharan Africa (SSA and Asia. Some individual level factors have been identified as risk factors for LBW but knowledge is limited on contextual risk factors for LBW especially in SSA.Contextual risk factors for LBW in Ghana were identified by performing multivariable multilevel logistic regression analysis of 6,900 mothers dwelling in 412 communities that participated in the 2003 and 2008 Demographic and Health Surveys in Ghana.Contextual-level factors were significantly associated with LBW: Being a rural dweller increased the likelihood of having a LBW infant by 43% (OR 1.43; 95% CI 1.01-2.01; P-value <0.05 while living in poverty-concentrated communities increased the risk of having a LBW infant twofold (OR 2.16; 95% CI 1.29-3.61; P-value <0.01. In neighbourhoods with a high coverage of safe water supply the odds of having a LBW infant reduced by 28% (OR 0.74; 95% CI 0.57-0.96; P-value <0.05.This study showed contextual risk factors to have independent effects on the prevalence of LBW infants. Being a rural dweller, living in a community with a high concentration of poverty and a low coverage of safe water supply were found to increase the prevalence of LBW infants. Implementing appropriate community-based intervention programmes will likely reduce the occurrence of LBW infants.

Full Text Available Prevention plays a crucial role in counteracting morbidity and mortality related to ischemic stroke. It has been estimated that 50% of stroke are preventable through control of modifiable risk factors and lifestyle changes. Antihypertensive treatment is recommended for both prevention of recurrent stroke and other vascular events. The use of antiplatelets and statins has been shown to reduce the risk of recurrent stroke and other vascular events. Angiotensin-converting enzyme inhibitors (ACEIs and angiotensin II receptor blockers (ARBs are indicated in stroke prevention because they also promote vascular health. Effective secondary-prevention strategies for selected patients include carotid revascularization for high-grade carotid stenosis and vitamin K antagonist treatment for atrial fibrillation. The results of recent clinical trials investigating new anticoagulants (factor Xa inhibitors and direct thrombin inhibitors clearly indicate alternative strategies in stroke prevention for patients with atrial fibrillation. This paper describes the current landscape and developments in stroke prevention with special reference to medical treatment in secondary prevention of ischemic stroke.
Full Text Available E Duron, Olivier HanonBroca Hospital, Paris, FranceAbstract: Dementia is one of the most important neurological disorders in the elderly. Aging is associated with a large increase in the prevalence and incidence of degenerative (Alzheimer’s disease and vascular dementia, leading to a devastating loss of autonomy. In view of the increasing longevity of populations worldwide, prevention of dementia has turned into a major public health challenge. In the past decade, several vascular risk factors have been found to be associated with vascular dementia but also Alzheimer’s disease. Some longitudinal studies, have found significant associations between hypertension, diabetus mellitus, and metabolic syndrome, assessed at middle age, and dementia. Studies assessing the link between hypercholesterolemia, atrial fibrillation, smoking, and dementia have given more conflicting results. Furthermore, some studies have highlighted the possible protective effect of antihypertensive therapy on cognition and some trials are evaluating the effects of statins and treatments for insulin resistance. Vascular risk factors and their treatments are a promising avenue of research for prevention of dementia, and further long-term, placebo-controlled, randomized studies, need to be performed.Keywords: dementia, hypertension, diabetus mellitus, hypercholesterolemia, metabolic syndrome

Previous studies on risk factors of obstructive sleep apnea (OSA) are highly controversial and mostly identifying a few cephalometric risk factors. OSA diagnosis was made according to the patients' apnea-hypopnea index (AHI). Included were 74 OSA patients (AHI > 10) and 52 control subjects (AHI ≤ 10 + free of other OSA symptoms). In both groups, 18 cephalometric parameters were traced (SNA, SNB, ANB, the soft palate's length (PNS-P), inferior airway space, the distance from the mandibular plane to the hyoid (MP-H), lengths of mandible (Go-Gn) and maxilla (PNS-ANS), vertical height of airway (VAL), vertical height of the posterior maxilla (S-PNS), superior posterior airway space (SPAS), middle airway space, distances from hyoid to third cervical vertebra and retrognathion (HH1), C3 (C3H), and RGN (HRGN), the maximum thickness of soft palate (MPT), tongue length (TGL), and the maximum height of tongue). These parameters were compared using t-test. Significant variables were SPAS (p = 0.027), MPT, TGL, HH1, C3H, HRGN, PNS-P, S-PNS, MP-H, VAL, and Go-Gn (all p values ≤ 0.006). OSA patients exhibited thicker and longer soft palates, hyoid bones more distant from the vertebrae, retrognathion, and mandibular plane, higher posterior maxillae, longer mandibles, and smaller superior-posterior airways.

The was to study the natural course of pneumothorax produced after aspiration biopsy in the attempt to differentiate those cases that will resolve spontaneously from those that will require drainage, and to assess the possible risk factors associated with the development of this entity. Eighty-nine CT-guided aspiration biopsies were performed in 80 patients. Control CT was done immediately after the procedure and 24 hours later. When pneumothorax persisted, CT was repeated at 48 h, 72 h, day 5 and day 7 or until a drainage tube was introduced. The cases of pneumothorax were classified as minimal, anterior or anterolateral. Seven variables were assessed as possible risk factors for its occurrence. Pneumothorax developed on 29 occasions (32.5%), requiring drainage in 12 cases (13.5%). In 20 patients (22%), pneumothorax occurred immediately, while in the remaining 9 (10%) it was detected in the 24 h CT scan. When studied according to type, drainage was required in 3 of the 19 cases of minimal or anterior pneumothorax (15%) and in 9 or the 10 cases of anterolateral location (90%) (p<0.0005). The mean thickness of the parenchyma punctured was 3.4 cm +- 2.2. cm when pneumothorax developed and 1.3 cm+- 2 cm when it did not (p<0.0001). There is a statistically significant association between the development of anterolateral pneumothorax and the need for chest drainage. The thickness of the punctured parenchyma is associated with the production of pneumothorax. 16 refs

This new trend of talks, and the natural desire to explore sexuality has led young people interested at phenomenon known as sexting. This phenomenon, from some of the negative consequences became public, has attracted the interest from parents, teachers, researchers and health workers, however, have not been universally well defined. This lack of unanimous conceptualization has led to confusion within the psychological, social and legal area. That is why in the present article presents results of a systematic review of articles that speak about sexting. The select articles were those that were published from 2009 to 2014, in which work was focused to adolescents and speak about risk factors and consequences of the phenomenon. The articles were analyzed by looking at the similarities and differences in their definition of sexting and their results, identifying risk factors and consequences related considered. With the analysis was possible to categorize their limitations and finally offer a possible definition of sexting.
Full Text Available The study of the adolescent pregnancy has been historically centered in the mother, the preponderant focus has been considers the maternity in this stage of the vital cycle as a factor of risk. Nowadays, have begun some studies that focus the problem of the adolescent pregnancy being centered in the father’s figure to appear and proposing a healthy focus, starting from the introduction of such concepts like Resilience. The present article, is a theoretical work, it is carried out to leave of secondary data. The objective is the compilation of studies and information on the subject of adolescent fatherhood from a less explored focus, considering the factors of risk and resilience. Different studies are raised with Latin American youths. Also are analyzed the access possibilities to the sanitary system from the youths, the knowledge of birth-control methods and the participation in programs of reproductive health. It outlines the importance of including the males in the whole process of procreation and the boy’s upbringing.
Full Text Available Post-transplant erythrocytosis (PTE is characterized by persistently ele-vated hematocrit level 0 51%. This complication is reported to develop in 10-20% of renal allografts recipients, mostly 2 years after kidney transplantation. PTE is self-limited in 25% of the patients; however it may persist in patients with an increased susceptibility for thrombosis and potential fatal outcome. To evaluate the prevalence and risk factors of PTE in our center, we reviewed the records of 235 patients who received renal allografts from 1999 to 2004. Polycythemia was found in 45 (19% patients. There was no significant correlation of polycythemia and age, history of hypertension, diabetes, pre-transplant hematocrit level, pre-transplant history of transfusion, graft′s function, and source of kidney. A significantly higher proportion of PTE patients were males, patients with history of polycystic kidney disease, and patients with glomerulonephritis. We conclude that PTE is an important complication of kidney transplantation. There are several risk factors that should be addressed to prevent this complication.

We performed a population survey of telemark skiers over two ski seasons to determine specific risk factors for injury. The survey inquired about the skier's sex, experience, equipment used, injuries, and number of days skied in each season. The respondents completed the surveys whether or not they were injured while skiing. We received 677 responses from telemark skiing clubs, with 19,962 skier-days of data. The number of self-reported injuries was 178, for an overall self-reported injury rate of 8.9 per 1000 skier-days. Knee injuries (N = 48) were the most common injury (27%), followed by thumb (N = 32, 18%) and shoulder (N = 21, 12%) injuries. Specific risk factors for injury were identified with multivariate regression and survival analysis. The skill level of the skier had a significant injury-sparing effect, as did the use of plastic telemark boots. The protective effect of the plastic boots was likely due to the increased stability they provided compared with traditional leather boots. There were fewer knee injuries with the recently available releasable bindings for telemark skis. Sex and age had no significant impact on injury rates in this study population. As all reported deaths associated with telemark sking were due to environmental hazards, skiers must continue to pay close attention to these hazards in the backcountry.
Full Text Available Weather and climate risk factors for tourism are surveyed and illustrated with regard to the expected climate changes in Hungary. These changes are not at all advantageous and which affect the business in question both directly and indirectly. These are the summer resort tourism (characterised by bioclimatic indices. Green tourism is the next one to characterise, including skiing, mountain climbing and eco-tourism, as well. Here both day-to-day weather extremes and long-lasting effects on the biota (e.g. drought, or inundation for plain-area eco-tourism. Last, but not least the urban (cultural- and shopping- tourism is presented, since the large towns exhibit their special climate and different risks. The paper intends to specify these meteorological factors and effects also in terms of the different types of touristic activities. The general statements on the effect of weather and climate on tourism are illustrated by a few individual parameters and also by the so called Physiologically Equivalent Temperature. Annual and diurnal course of this parameter are presented, together with various trends in this variable at different sites and in different (hot and cold extremities of the occurring values. Other examples, helping the tourism industry are presented in various climate conditions of the country. They include high precipitation and high relative humidity information. The paper also lists the possible adaptation measures to extreme events and also their likely changes in time.
Full Text Available Aim: Many etiological factors play a role in the occurrence of postoperative empyema. We aimed to define the effects of these factors on the development of empyema. Material and Method: Two hundred and eighty-eight cases from our clinic who underwent tube thoracostomy and/or were operated due to any cause out of the primary empyema between August 2009 and May 2010 were prospectively studied in terms of empyema development. Data comprised gender, age, chemoradiotherapy, surgical procedure, intraoperative thoracic lavage with povidone-iodine, emergency surgery status, sharing the same room with other cases with empyema, primary disease, additional comorbidity, operation duration, drain number, complication, number of patients in the room, and drain discontinuation and hospitalization duration. Blood leukocyte-neutrophil count was ordered in all cases at 3-day intervals, and fluid culture specimens were simultaneously collected from cases with drains. Drainage fluid culture specimens were evaluated with “Automated Identification and Antibiotic Susceptibility Testing” using standard procedures. Empyema cases who developed clinical manifestation and/or with bacterial growth in culture specimens were studied in terms of risk factors. The findings were analyzed using SPSS (version 16. Results: The results showed that gender, age, chemoradiotherapy, surgical procedure, intraoperative thoracic lavage with povidone-iodine, emergency surgery status, and sharing a same room with other empyema cases were not significantly correlated with the risk of empyema development. Contribution of the primary disease (p<0.05, additional comorbidity (p<0.05, operation duration (p<0.05, drain number (p<0.05, complication (p<0.05, number of people in the room (p<0.05, drain discontinuation time (p<0.05 and hospitalization duration (p<0.05 were found to be significant in the development of postoperative empyema.

To identify the risk factors associated with childhood asthma, in children attending Isra University Hospital, Hyderabad. The study included 398 age-matched children (200 asthmatic and 198 non-asthmatic). Information was collected concerning their familial history of atopy, birth weight, environment, breastfeeding, disease and treatment history. Odds ratio was calculated for determining the risk. The children were aged between 12 months and 8 years and 60% were male. The asthmatic children were hospitalized more frequently than the non-asthmatic children (p < 0.0001). Most of the asthmatic children lived in the urban areas of Hyderabad (odd ratio (OR) 16.7, 95% CI = 3.1-14.6, p < 0.0001), had a parental history of asthma (OR 26.8, 95% CI = 10.8-68.2, p < 0.0001) or allergic rhinitis (OR 4, 95% CI 1.2-13.4, p= 0.01), 38.5% had at least one person who smoked, and were weaned earlier than the non-asthmatic children (OR =12.4, 95% CI 1.3-4.4, p < 0.01). Childhood asthma was strongly associated with a family history of asthma and allergic rhinitis, the urban place of residence, having smokers as parents and early weaning from maternal breast milk. The results highlight the need to educate the parents about the risk of smoking and early weaning in the development of asthma. (author)
Full Text Available Falls are the leading accidental cause of death among elderly people in their homes. Falls and their consequences are the primary reason in 40% of admissions to hospitals for people older than 65 years. The study population consisted of 77 randomly selected patients of both genders older then 65 years. Each patient was tested in his/her home and was completely informed about the methodology and the goals of investigation. Based on the exclusion criteria, three patients were excluded from the study, which means the investigation was conducted on 27 males (35.06% and 50 females (64.94% with the average age being 71.23 ± 5.63 years.For each patient, a specially prepared questionnaire about risk factors was filled in. The sum of affirmative answers represented a relative index of fall risk. All patients were evaluated through Folstein’s Mini-Mental State Examination Test that is suitable for on-sight use in patient’s home. The score value over 20 excludes dementias, delirium, schizophrenia and affective disorders.Considering the values of the risk factor, scores obtained by the questionnaire and MMSE test scores, statistically significant differences were found between males and females (p < 0.005, respectively p < 0.01, “fallers” and “non-fallers” (p < 0.001, respectively p < 0.01, while considering the relation to the way of living (alone or with family, there were no statistically significant differences (p > 0.05.
Full Text Available AbstractObjectives: to assess nurses' perceptions of risk factors for the development of phlebitis, with a special focus on the perception of phlebitic potentials of some infusion medications and solutions.Method: a cross-sectional questionnaire study, which included a sample of 102 nurses.Results: Nurses recognized some factors that may reduce the incidence of phlebitis; however, more than half of the nurses were unaware that the material and diameter of the cannula can affect the incidence rate of phlebitis. Furthermore,underlying disease and high pH of medications or solutions were identified as potential risk factors, whereas low pH and low osmolality were not. Nurses identified Vancomycin and Benzylpenicillin antibiotics with the strongest phlebitic potential. Among other medications and intravenous fluids, Aminophylline, Amiodaronehydrochloride and Potassium chloride 7.4% were identified as potentially causing phlebitis.Conclusion: predisposing factors for phlebitis relating to patients and administered therapy were identified by nurses, while some cannula related risk factors, in particular its physicochemical properties and the time for cannula replacement, were not fully perceived.

Full Text Available Abstract OBJECTIVE: To investigate the risk factors for postpartum urinary incontinence (UI and its characteristics. METHOD: This was a case-control study with 344 puerperal women (77 cases and 267 controls with up to 90 days postpartum. In a single session, participants were given a questionnaire with sociodemographic and clinical data and two others that assessed urine leakage, leakage situations, and type of UI. RESULTS: Stress UI was present in 45.5% of the women, incidents of urine leakage several times a day in 44.2%, of which 71.4% were in small amounts and 57.1% when coughing or sneezing. In 70.1% of cases, UI began during pregnancy and remained through the postpartum period. After running a binary logistic regression model, the following factors remained in the final model: UI during pregnancy (OR 12.82, CI 95% 6.94 - 23.81, p<0.0001, multiparity (OR 2.26, CI 95% 1.22 - 4.19, p=0.009, gestational age at birth greater or equal to 37 weeks (OR 2.52, CI 95% 1.16 - 5.46, p=0.02 and constipation (OR 1.94, CI 95% 1.05 - 5.46, p=0.035. CONCLUSION: Most often, UI first appeared during pregnancy and remained through the postpartum period. Urinary incontinence during pregnancy, multiparity, gestational age at birth greater or equal to 37 weeks, and constipation were presented as risk factors. In the studied group, stress UI was more frequent.

To assess the severity and frequency of hepatotoxicity caused by different antituberculosis (ATT) drugs and to evaluate whether concurrence of risk factors influence the antituberculosis drug induced hepatotoxicity. This prospective cohort study was conducted in Medical Unit-V and OPD department of Civil Hospital Karachi from July 2004 to July 2005. A total of 339 patients diagnosed of active tuberculosis infection with normal pretreatment liver function were monitored clinically as well as biochemically. Their data were collected on proforma and patients were treated with Isoniazid, Rifampicin and Pyrazinamide. Duration after which derangement in function, if any, occurred and time taken for normalization was noted. Treatment was altered as needed, with exclusion of culprit drug. Finally data was analyzed by SPSS version 10.0. ATT induced hepatotoxicity was seen in 67 (19.76%) out of 339 patients. Females were more affected as compared to males (26.3% vs. 19.7%). BMI (kg/m2) of 91% of diseased group were less than 18.5 (p<0.01) most of them were anemic having low albumin level suggestive of lean body mass. Hepatotoxicity was more severe in AFB smear positive patients. Concomitant use of alcohol, paracetamol and low serum cholesterol were proved as predisposing factors. Isoniazid (37 patients (55.21%), p<0.01) was the main culprit followed by Rifampicin (23 patients, 34.21%) and Pyrazinamide (7 patients, 10.5%). Most of the patients (61%) developed the hepatotoxicity within two weeks of starting antituberculosis therapy with mild to moderate alteration in ALT and AST. ATT-induced hepatitis is significantly more frequent and more severe in patients with hepatotoxicity risk factors. (author)
Full Text Available Background/Aim. Recurrent vulvovaginal candidiasis is relatively frequent condition, and may have serious health consequences, like chronic vulvovaginal pain syndrome. The aim of our study was to determine possible risk factors for recurrent vulvovaginal candidiasis in non-pregnant females within the reproductive age. Methods. The design of our study was of a case-control type. Case and control patients were selected from the gynecological patients at six primary care facilities in Serbia and in Montenegro. The data on the patients' health condition, concomitant therapy and diseases were taken from their records, and the data on habits were obtained by unstructured interview. For potential risk factors crude odds ratios were calculated, and then adjusted by logistic regression. Results. A total of fifty-one patients had four or more episodes of vulvovaginal candidiasis during the last year (cases, and 132 patients with one to three episodes of vulvovaginal candidiasis were sampled as controls, matched by age. The only two significant associations were found between recurrent vulvovaginal candidiasis and continual wearing of panty liners during the last year (Odds ratio - ORadjusted: 3.97; confidence interval - CI: 1.57-10.02; p = 0.004, and between recurrent vulvovaginal candidiasis and predominant use of vaginal tampons during menstruation in the last year (ORadjusted: 4.25; CI: 1.11-16.27; p = 0.035. The synergistic effect was observed for the concurrent continual wearing of panty liners during the last year and selfmedication with antimycotics. Conclusions. Local factors, like wearing of panty liners or use of tampons during menstruation, may promote recurrence of vulvovaginal candidiasis, especially in patients who practice selfmedication with antimycotics.

This article reviews the literature on genetic aspects of dental caries and provides a framework for the rapidly changing disease model of caries. The scope is genetic aspects of various dental factors affecting dental caries. The PubMed database was searched for articles with keywords 'caries', 'genetics', 'taste', 'diet' and 'twins'. This was followed by extensive handsearching using reference lists from relevant articles. The post-genomic era will present many opportunities for improvement in oral health care but will also present a multitude of challenges. We can conclude from the literature that genes have a role to play in dental caries; however, both environmental and genetic factors have been implicated in the aetiology of caries. Additional studies will have to be conducted to replicate the findings in a different population. Identification of genetic risk factors will help screen and identify susceptible patients to better understand the contribution of genes in caries aetiopathogenesis. Information derived from these diverse studies will provide new tools to target individuals and/or populations for a more efficient and effective implementation of newer preventive measures and diagnostic and novel therapeutic approaches in the management of this disease. © 2015 Australian Dental Association.

Full Text Available Sexual transmission of HIV requires exposure to the virus and infection of activated mucosal immune cells, specifically CD4+ T cells or dendritic cells. The foreskin is a major site of viral entry in heterosexual transmission of HIV. Although the probability of acquiring HIV from a sexual encounter is low, the risk varies even after adjusting for known HIV risk factors. The genital microbiome may account for some of the variability in risk by interacting with the host immune system to trigger inflammatory responses that mediate the infection of mucosal immune cells. We conducted a case-control study of uncircumcised participants nested within a randomized-controlled trial of male circumcision in Rakai, Uganda. Using penile (coronal sulcus swabs collected by study personnel at trial enrollment, we characterized the penile microbiome by sequencing and real-time PCR and cytokine levels by electrochemiluminescence assays. The absolute abundances of penile anaerobes at enrollment were associated with later risk of HIV seroconversion, with a 10-fold increase in Prevotella, Dialister, Finegoldia, and Peptoniphilus increasing the odds of HIV acquisition by 54 to 63%, after controlling for other known HIV risk factors. Increased abundances of anaerobic bacteria were also correlated with increased cytokines, including interleukin-8, which can trigger an inflammatory response that recruits susceptible immune cells, suggesting a mechanism underlying the increased risk. These same anaerobic genera can be shared between heterosexual partners and are associated with increased HIV acquisition in women, pointing to anaerobic dysbiosis in the genital microbiome and an accompanying inflammatory response as a novel, independent, and transmissible risk factor for HIV infection.

Full Text Available One of the most important components in today's market is a party decision-making under risk and uncertainty. The first step in making such decisions - to adequately process the information for estimating the future value of assets and the interests of investors probabilities of each particular scenario. The next step is to choose the alternative that has the greatest utility for the investor. Each of these steps is associated with numerous difficulties, the roots of which stem from the specificity of human psychology. The article notes that an integral part of professional risk management is to identify the nature of the object of management in the sphere of economy. Since the domestic theory of risk management is being formed-tion, the problem of a clear comprehensive definition of “risk” becomes now particularly relevant-ness. The article deals with along with economic forecasts of the risks and the human factor in decision-tions solutions. Along with economic forecasts, the report focuses on psychological problems and attempts to take into account the human factor in decision-making at the forecast of risks arising in the company. The important parameters are the status and position of the person in the society, as well as its social well-being. Analysis Meto-ing risk assessment concluded that the need to develop new models and methods of risk management, taking into account the four-lovecheskogo factor. Economic psychology and its applications have developed into a special branch of economic knowledge - the so-called behavioral economics, which surely develops a wide range of economic issues - from the actual theory of individual behavior to the problems of public choice and the financial economy. The most interesting item is the fact that the concept of “risk” is considered from different points of view - as the economist-mathematician with the position, and a psychologist.
Full Text Available The article analyses the effect of two ambient scents (peppermint and vanilla and their intensiveness on risk related behaviour that is expressed through selected decision making heuristics. Purpose of the article: The purpose of this article is to identify the relationship of ambient scent type and intensiveness with risk related behaviour that is expressed through selected decision making heuristics. Methodology/methods: 2×2 factorial experiment with control group was run. Ambient scent type (vanilla vs. peppermint and intensiveness (8 (1mg vs. 16 sprays (2mg of scent concentrate in the same room were manipulated as between subject variables. Risk aversion, effect of anchoring heuristic on bidding, and affect (risk and benefit heuristics were tracked as dependent variables. Scientific aim: To identify whether ambient scent type and intensiveness have effect on risk related behaviour. Findings: Evidence suggests that there are effects of ambient scent on risk related behaviour, thus fulfilling the missing gap to relate ambient environment to decision making heuristics when risks are involved. However, not all heuristics were affected by experimental conditions. Subjects were bidding significantly higher amounts under low anchor conditions, when peppermint scent was around (if compared to vanilla group. Affect risk was perceived as lower in peppermint ambient scent conditions, if compared to the control group. Intensity of ambient scent also had influence on affect risk: subjects perceived less risk under high scent intensity conditions. Conclusions: By manipulating ambient scent, marketers may reduce or increase consumers risk perception and behaviour and as a consequence influence their purchase decisions. Marketers could use peppermint scent in high intensiveness in the situations where they want consumers to undertake higher risks (expensive purchases, gambling, insurance, since stakes were higher under peppermint ambient scent condition

The database was queried for data related to the surgical procedure, anesthetic care, perioperative adverse events, and birth/death/operation dates. The 48 h and 30 d cumulative incidence of postoperative mortality was calculated and data were analyzed using Chi-square or Fisher’s exact test and generalized estimating equations.Results: The 48 h and 30 d incidence of postoperative mortality was 0.57% and 2.1%, respectively. Higher American Society of Anesthesiologists physical status scores, extremes of age, emergencies, perioperative adverse events and postoperative Intensive Care Unit admission were identified as risk factors. The use of monitored anesthesia care or general anesthesia versus regional or combined anesthesia was a risk factor for 30 d postoperative mortality only. Time under anesthesia care, perioperative hypothermia, trauma, deliberate hypotension and invasive monitoring via arterial, pulmonary artery or cardiovascular catheters were not identified as risk factors.Conclusions: Our findings can be used to track postoperative mortality rates and to test preventative interventions at our institution and elsewhere.Keywords: postoperative mortality, risk factors, operations, anesthesia, inpatient surgery

Full Text Available The aim of the research – assess risk factors for very preterm delivery in the Omsk region. Materials and methods. The main group comprised women with very preterm delivery (n = 64; сomparison group – pregnant women with a threat of interruption in terms of 22-27 weeks and successful preserving therapy (n = 63; control group – pregnant women in whom this pregnancy was taking place without the threat of interruption (n = 62. Results. Risk factors for very preterm delivery were bacterial vaginosis, specific vaginitis, kidney disease and the threat of interruption. There was a significant lead in streptococci (32.3 ± 5.8 %, especially group B (19.0 ± 4.9 % in the main group. The risk factor for very preterm delivery was infectious viral diseases transferred during pregnancy, observed in 12.7 ± 4.2 % of women in the main group, in 7.8 ± 3.3 % in the comparison group (p < 0.01 and in 4.8 ± 2,7 % – control (p < 0,001. In the main group, placental insufficiency was 2 times more common than in the comparison group and 13 times than in the control group. Every sixth pregnant of the main group had manifestations of gestosis. Such complications of gestation as the premature detachment of the normally inserted placenta (7.8 ± 3.3 % and inborn malformations of a fruit (1.6 ± 1.6 % were observed only in the main group. Conclusion. The results of the research and literature data showed that the significant influence on the level of very early premature births is due to: the age of the parents, the abuse of nicotine, alcohol, drugs, abortion, preterm birth, urinary tract and genital tract infections, severe somatic diseases, multiple pregnancies. In the structure of complications of gestation during miscarriages, placental insufficiency predominates, the threat of abortion, fetal growth retardation, and polyhydramnios.

The samples were pregnant women who had ectopic pregnancy at Maternity Room, Emergency Unit, Dr. Soetomo Hospital, Surabaya, from 1 July 2008 to 1 July 2010. Sampling technique was total sampling using medical records. Result: Patients with ectopic pregnancy were 99 individuals out of 2090 pregnant women who searched for treatment in Dr. Soetomo Hospital. However, only 29 patients were accompanied with traceable risk factors. Discussion:. Most ectopic pregnancies were in the age group of 26-30 years, comprising 32 patients (32.32%, then in age groups of 31–35 years as many as 25 patients (25.25%, 18 patients in age group 21–25 years (18.18%, 17 patients in age group 36–40 years (17.17%, 4 patients in age group 41 years and more (4.04%, and the least was in age group of 16–20 years with 3 patients (3.03%. A total of 12 patients with ectopic pregnancy (41.38% had experience of abortion and 6 patients (20.69% each in groups of patients with ectopic pregnancy who used family planning, in those who used family planning as well as ectopic pregnancy patients with history of surgery. There were 2 patients (6.90% of the group of patients ectopic pregnancy who had history of surgery and history of abortion. The incidence rate of ectopic pregnancy was 4.73%, mostly in the second gravidity (34.34%, whereas the nulliparous have the highest prevalence of 39.39%. Acquired risk factors, i.e. history of operations was 10.34%, patients with family planning 20.69%, patients with history of abortion 41.38%, patients with history of abortion and operation 6.90% patients with family and history of abortion was 20.69%.
Full Text Available In this study, we investigate the new and standardized European system of supervisory called Solvency II. In essence, asymmetric distribution of information between policyholder and insurer triggered this new regulation which aims at better protecting policyholders. Its three-pillar model is about to challenge both, insurers as well as policyholders. The first pillar includes quantitative aspects, the second pillar contains qualitative aspects and the third pillar comprises market transparency and reporting obligations. Underwriting risks, the default risk of a bank and market risks can be identified for the dynamic hybrid. Solvency II covers all these risks in the first pillar and insurers shall deposit sufficient risk-bearing capital. In our analysis, we first identify the dynamic hybrid specific risks under the Solvency II regime und then develop product modifications to reduce this risk.

Its caused by dengue virus, transmitted by Aedes mosquitoes. The case is spread in the tropics, especially in Southeast Asia, Central America, America and the Caribbean, many causes of death in children 90% of them attacking children under 15 years old. Until now pathogenesis is unclear. There are two theories or hypotheses immuno-patogenesis DHF and DSS is still controversial which secondary infections (secondary heterologus infection and antibody-dependent enhancement. Risk factors for dengue transmission are rapid urban population growth, mobilization of the population because of improved transportation facilities and disrupted or weakened so that population control. Another risk factor is poverty which result in people not has the ability to provide a decent home and healthy, drinking water supply and proper waste disposal.
Introduction: Osteoradionecrosis (ORN) of the jaws is defined as exposed irradiated bone that fails to heal over a period of 3 months without the evidence of a persisting or recurrent tumor. In the previous decades, numerous factors were associated with the risk of ORN development and severity. Aims: The purposes of this study were to present the data of the patients that were treated for ORN in the Department of Oral and Maxillofacial Surgery in Munich (LMU), to detect factors that contributed to the onset of ORN, to identify risk factors associated with the severity of ORN and finally, to delineate and correlate these factors with the personal, health and treatment characteristics of the patients. Material and Methods: A retrospective study was conducted during the period from January 2003 until December 2012 that included all ORN cases having been treated in the Department of Oral and Maxillofacial Surgery in Munich (LMU). The total sample was categorized in three groups according to stage and several variables were evaluated in an attempt to identify possible correlations between them and the necrosis severity. Results: One hundred and fifty three cases of ORN were documented. Among them, 23 (15.1%) cases were stage I, 31 (20.2%) were stage II and 99 (64.7%) were stage III and all localised in the mandible. There was a predominance of the disease in the posterior region when compared to the anterior region. The majority of cases was addicted to alcohol and tobacco abuse and was suffering from Diabetes Mellitus (DM). All cases were treated with RT and 80.4% of them with concomitant chemotherapy. The initial tumor was predominantly located in the floor of the mouth, the tongue and the pharynx. Approximately two thirds of the cases occured either after dental treatment or due to a local pathological condition. Logistic regression analysis identified Diabetes Mellitus (OR: 4.955, 95% Cl: 1.965-12.495), active smoking (OR: 13.542, 95% Cl: 2.085-87.947), excessive

The burnout syndrome is characterized by emotional exhaustion, depersonalization and reduced personal accomplishment in individuals professionally involved with others. The burnout syndrome is poorly recognized, particularly in France, as a distinct nosology from adaptation troubles, stress, depression, or anxiety. Several tools quantifying burnout and emotional exhaustion exist, the most spread is the questionnaire called Maslach Burnout Inventory. The burnout syndrome alters cardiovascular function and its neuroregulation by autonomic nervous system and is associated with: increased sympathetic tone to heart and vessels after mental stress, lowered physiological post-stress vagal rebound to heart, and lowered arterial baroreflex sensitivity. Job strain as burnout syndrome seems to be a real independent cardiovascular risk factor. Oppositely, training to manage emotions could increase vagal tone to heart and should be cardio-protective.

Full Text Available Cholangiocarcinoma (CCA is a very aggressive and lethal tumor, which arises from the epithelial cells of bile ducts. CCA comprises about 3% of all gastrointestinal malignancies and its incidence is on the rise in the recent years. Anatomically, it is classified into intrahepatic, perihilar, or extrahepatic (distal CCA. There are a number of risk factors associated with CCA including primary sclerosing cholangitis, fibropolycystic liver disease, parasitic infection, viral hepatitis, chronic liver disease, and genetic disorders like Lynch syndrome. Autoimmune hepatitis is also recently reported to have an association with development of CCA. We report an interesting case of perihilar CCA in the setting of autoimmune hepatitis along with a literature review. This case highlights the importance of early treatment and close clinical follow-up of patients with autoimmune hepatitis for development of CCA.

This article reviews central findings and current developments of psychological and sociological research on the perception of health risks. Risk perception is influenced by numerous psychological, social, political, and cultural factors. These factors can be categorized into (a) risk characteristics, (b) characteristics of the risk perceiving person and his/her situation, and (c) characteristics of risk communication. Thus, besides individual cognitive and affective processing of risk information, social processes of risk amplification (e.g., media effects) are also involved in the construction of individual risk perceptions. We discuss the recommendations for health risk communication that follow from these findings with regard to different communication goals.

To clarify sleep disorder risk factors among student athletes, this study examined the relationship between lifestyle habits, competition activities, psychological distress, and sleep disorders. Student athletes (N = 906; male: 70.1%; average age: 19.1 ± 0.8 years) in five university sports departments from four Japanese regions were targeted for analysis. Survey items were attributes (age, gender, and body mass index), sleep disorders (recorded through the Pittsburgh Sleep Quality Index), lifestyle habits (bedtime, wake-up time, smoking, drinking alcohol, meals, part-time jobs, and use of electronics after lights out), competition activities (activity contents and competition stressors), and psychological distress (recorded through the K6 scale). The relation between lifestyle habits, competition activities, psychological distress, and sleep disorders was explored using logistic regression analysis. Results of multivariate logistic regression analysis with attributes as adjustment variables showed that "bedtime," "wake-up time," "psychological distress," "part-time jobs," "smartphone/cellphone use after lights out," "morning practices," and "motivation loss stressors," were risk factors that were independently related to sleep disorders. Sleep disorders among student athletes are related to lifestyle habits such as late bedtime, early wake-up time, late night part-time jobs, and use of smartphones/cellphones after lights out; psychological distress; and competition activities such as morning practices and motivation loss stressors related to competition. Therefore, this study suggests the importance of improving these lifestyle habits, mental health, and competition activities. Copyright © 2017 Elsevier B.V. All rights reserved.

Fatigue is one of the most common and distressing side effects of cancer and its treatment, and may persist for years after treatment completion in otherwise healthy survivors. Cancer-related fatigue causes disruption in all aspects of quality of life and may be a risk factor for reduced survival. The prevalence and course of fatigue in cancer patients has been well characterized, and there is growing understanding of underlying biological mechanisms. Inflammation has emerged as a key biological pathway for cancer-related fatigue, with studies documenting links between markers of inflammation and fatigue before, during, and particularly after treatment. There is considerable variability in the experience of cancer-related fatigue that is not explained by disease- or treatment-related characteristics, suggesting that host factors may play an important role in the development and persistence of this symptom. Indeed, longitudinal studies have begun to identify genetic, biological, psychosocial, and behavioral risk factors for cancer-related fatigue. Given the multi-factorial nature of cancer-related fatigue, a variety of intervention approaches have been examined in randomized controlled trials, including physical activity, psychosocial, mind-body, and pharmacological treatments. Although there is currently no gold standard for treating fatigue, several of these approaches have shown beneficial effects and can be recommended to patients. This report provides a state of the science review of mechanisms, risk factors, and interventions for cancer-related fatigue, with a focus on recent longitudinal studies and randomized trials that have targeted fatigued patients.

Background: Detection of women at risk for dystocia will allow physicians to make preparations and treatment decisions that can minimize maternal and neonatal morbidity. We aimed to determine the risk factors for dystocia in nulliparous women. Methods: This case series enrolled 447 nulliparous women who presented with a single pregnancy in the vertex presentation and gestational age of 38-42 weeks. Maternal anthropometric measurements were obtained upon admission. We defined dystocia as a cesarean section or vacuum delivery for abnormal progression of labor as evidenced by the presence of effective uterine contractions, cervical dilation of less than 1 cm/h in the active phase for 2 h, duration of the second stage beyond 2 h, or fetal head descent less than 1 cm/h. Data were analyzed by SPSS software version 11.5. Kruskal-Wallis, logistic regression, chi-square, Student’s t test and the Mann-Whitney tests were used as appropriated. Results: The state anxiety score (OR=10.58, CI: 1.97-56.0), posterior head position (OR=9.53, CI: 4.68-19.36), fetal head swelling in the second stage of labor (OR=6.85, CI: 2.60-18.01), transverse diagonal of Michaelis sacral ≤9.6 cm (OR=6.19, CI: 2.49-15.40), and height to fundal ratio dystocia. Conclusion: Critical care during labor and delivery in women who have a height to fundal height ratio of dystocia. PMID:24850982

It is well recognized that patients with end stage renal diseases (ESRD) have hyper-plastic parathyroid glands. In most patients, a decrease in parathyroid hormone (PTH) occurs by about 1 year after renal transplantation. However, some renal transplant recipients continue to have elevated level of PTH. We prospectively evaluated 121 patients undergoing renal transplantation between August 2000 and 2002. The duration of dialysis, calcium (Ca), phosphorus (P), albumin, creatinine and iPTH levels were recorded prior to transplantation and three months and one year after transplantation. These 121 patients were on dialysis for an average period of 17.4 months prior to transplantation. An increase in the serum Ca and a decrease in serum P and iPTH level was seen in the patients after transplantation (P< 0.001). Hyperparathyroidism was in 12 (9.9%) and 7 (5.7%) patients three months and one year after transplantation respectively. Elderly patients and patients with longer duration on dialysis had an increased risk of developing post transplant hyperparathyroidism and hypercalcemia in the first year post transplant (P< 0.05). In conclusion age and duration on dialysis before transplantation seems to be important risk factors for post transplant hyperparathyroidism. (author)
Full Text Available The World Health Organization (WHO recognized diabetes as one of the four most important and priority health issues out of non-communicable diseases. According to a report by the WHO with the year 2016 the prevalence of diabetes for 3 decades and continues to grow, this problem applies to the entire world. In 2014. the number of diabetes patients brought the 422 million, by comparison, in 1980. It was 108 million. A badly aligned metabolically diabetes contributes to the development of numerous complications of micro-and macro-angiopathic, which are related to adverse prognosis and increase the risk of cardiovascular disease. Striving for the best possible alignment of the carbohydrate economy reduces both the mortality and cardiovascular. However, some patients with diabetes intensive glucose control is not effective and increases the incidence of severe hypoglycemia, which in turn some patients increases cardiovascular mortality. The aim of the work is the appearance of hypoglycemia as a factor that increases the risk of death in cardiovascular diseases. The work also emphasises the importance of cardiovascular diseases in diabetes, which are the most common complication of diabetes and the most common cause of death in this group of patients.

In models and scores for estimating cardiovascular risk (CVR), the relative weightings given to blood pressure measurements (BPMs), and biometric and laboratory variables are such that even large differences in blood pressure lead to rather low differences in the resulting total risk when compared with other concurrent risk factors. We evaluated this phenomenon based on the PROCAM score, using BPMs made by volunteer subjects at home (HBPMs) and automated ambulatory BPMs (ABPMs) carried out in the same subjects. A total of 153 volunteers provided the data needed to estimate their CVR by means of the PROCAM formula. Differences (deltaCVR) between the risk estimated by entering the ABPM and that estimated with the HBPM were compared with the differences (deltaBPM) between the ABPM and the corresponding HBPM. In addition to the median values (= second quartile), the first and third quartiles of blood pressure profiles were also considered. PROCAM risk values were converted to European Society of Cardiology (ESC) risk values and all participants were assigned to the risk groups low, medium and high. Based on the PROCAM score, 132 participants had a low risk for suffering myocardial infarction, 16 a medium risk and 5 a high risk. The calculated ESC scores classified 125 participants into the low-risk group, 26 into the medium- and 2 into the high-risk group for death from a cardiovascular event. Mean ABPM tended to be higher than mean HBPM. Use of mean systolic ABPM or HBPM in the PROCAM formula had no major impact on the risk level. Our observations are in agreement with the rather low weighting of blood pressure as risk determinant in the PROCAM score. BPMs assessed with different methods had relatively little impact on estimation of cardiovascular risk in the given context of other important determinants. The risk calculations in our unselected population reflect the given classification of Switzerland as a so-called cardiovascular "low risk country".

Given the increasing impacts of flooding in Jakarta, methods for assessing current and future flood risk are required. In this paper, we use the Damagescanner-Jakarta risk model to project changes in future river flood risk under scenarios of climate change, land subsidence, and land use change. Damagescanner-Jakarta is a simple flood risk model that estimates flood risk in terms of annual expected damage, based on input maps of flood hazard, exposure, and vulnerability. We estimate baseline flood risk at USD 186 million p.a. Combining all future scenarios, we simulate a median increase in risk of +180 % by 2030. The single driver with the largest contribution to that increase is land subsidence (+126 %). We simulated the impacts of climate change by combining two scenarios of sea level rise with simulations of changes in 1-day extreme precipitation totals from five global climate models (GCMs) forced by the four Representative Concentration Pathways (RCPs). The results are highly uncertain; the median change in risk due to climate change alone by 2030 is a decrease by -46 %, but we simulate an increase in risk under 12 of the 40 GCM-RCP-sea level rise combinations. Hence, we developed probabilistic risk scenarios to account for this uncertainty. If land use change by 2030 takes places according to the official Jakarta Spatial Plan 2030, risk could be reduced by 12 %. However, if land use change in the future continues at the same rate as the last 30 years, large increases in flood risk will take place. Finally, we discuss the relevance of the results for flood risk management in Jakarta.

Cardiovascular diseases (CVD) are responsible for around 20% of all deaths worldwide (approximately 14 million) and are the principal cause of death in all developed countries, accounting for 50% of all deaths. Variations in the annual per capita death rates in different countries are well documented. Less well known are seasonal variations in death rates, with the highest levels occurring during the colder winter months, which have been described in many countries. This phenomenon is referred to as excess winter mortality. CVD-related deaths account for the majority of excess winter deaths (up to 70% in some countries), while about half of the remaining are due to increases in respiratory diseases. Paradoxically, CVD mortality increases to a greater extent with a given fall in temperature in regions with warm winters. While much of the indirect evidence points to the notion that cold is somehow involved in explaining excess winter deaths, the mechanism by which seemingly mild exposure to cold ambient conditions can increase the risk of death remains unclear. The strong indirect epidemiological evidence coupling cold climate to mortality may be related to indoor rather than outdoor climatic conditions (e.g., cold/damp houses versus arm/dry houses) coupled with a plethora of factors including health status, ageing-related deterioration in physiological and behavioral thermoregulation, toxicology, and socioeconomic factors
Full Text Available Over the last two decades, the amount of evidence corroborating an association between dental plaque bacteria and coronary diseases that develop as a result of atherosclerosis has increased. These findings have brought a new aspect to the etiology of the disease. There are several mechanisms by which dental plaque bacteria may initiate or worsen atherosclerotic processes: activation of innate immunity, bacteremia related to dental treatment, and direct involvement of mediators activated by dental plaque and involvement of cytokines and heat shock proteins from dental plaque bacteria. There are common predisposing factors which influence both periodontitis and atherosclerosis. Both diseases can be initiated in early childhood, although the first symptoms may not appear until adulthood. The formation of lipid stripes has been reported in 10-year-old children and the increased prevalence of obesity in children and adolescents is a risk factor contributing to lipid stripes development. Endothelium damage caused by the formation of lipid stripes in early childhood may lead to bacteria penetrating into blood circulation after oral cavity procedures for children as well as for patients with aggressive and chronic periodontitis.

Test whether inadequate exercise is related to sepsis mortality. Mortality surveillance of an epidemiological cohort of 155,484 National Walkers' and Runners' Health Study participants residing in the United States. Deaths were monitored for an average of 11.6-years using the National Death index through December 31, 2008. Cox proportional hazard analyses were used to compare sepsis mortality (ICD-10 A40-41) to inadequate exercise (<1.07 METh/d run or walked) as measured on their baseline questionnaires. Deaths occurring within one year of the baseline survey were excluded. Sepsis was the underlying cause in 54 deaths (sepsis(underlying)) and a contributing cause in 184 deaths (sepsis(contributing)), or 238 total sepsis-related deaths (sepsis(total)). Inadequate exercise was associated with 2.24-fold increased risk for sepsis(underlying) (95%CI: 1.21 to 4.07-fold, P = 0.01), 2.11-fold increased risk for sepsis(contributing) (95%CI: 1.51- to 2.92-fold, P<10(-4)), and 2.13-fold increased risk for sepsis(total) (95%CI: 1.59- to 2.84-fold, P<10(-6)) when adjusted for age, sex, race, and cohort. The risk increase did not differ significantly between runners and walkers, by sex, or by age. Sepsis(total) risk was greater in diabetics (P = 10(-5)), cancer survivors (P = 0.0001), and heart attack survivors (P = 0.003) and increased with waist circumference (P = 0.0004). The sepsis(total) risk associated with inadequate exercise persisted when further adjusted for diabetes, prior cancer, prior heart attack and waist circumference, and when excluding deaths with cancer, or cardiovascular, respiratory, or genitourinary disease as the underlying cause. Inadequate exercise also increased sepsis(total) risk in 2163 baseline diabetics (4.78-fold, 95%CI: 2.1- to 13.8-fold, P = 0.0001) when adjusted, which was significantly greater (P = 0.03) than the adjusted risk increase in non-diabetics (1.80-fold, 95%CI: 1.30- to 2.46-fold, P = 0
Full Text Available Besides clinical medicine, which is in the process of constant and fast development, the focus is increasingly on public health services, which should be well prepared for reducing or keeping under control the dangers induced by the growing social burden of disease. Continuous risk management is represented by these services that are specially designed to prevent diseases and health damages. The grounds for the planning and implementation of public health services are constituted by risk factor management and assessment by means of adopting a unified approach.

Prescription medicine sharing has been defined as giving one's own medicine to someone else (lending) or taking someone else's medicine (borrowing). Medicines can be shared for non-medical purposes (recreational sharing or drug abuse) or for their intended therapeutic benefits (non-recreational sharing, e.g. sharing antibiotics to self-treat); the latter is the focus of this research. Limited research evidence is available about modifiable risk factors for non-recreational medicine sharing and addressing this issue was the main aim of this research. An online, cross-sectional survey design was used. The study population comprised a convenience sample of 233 adults, who were primarily recruited through patient support groups across New Zealand. Principal component analysis was used to develop scales assessing attitudes toward medicine lending and borrowing. Logistic regression was used to examine the relationship between explanatory (demographics, medical conditions, and attitudes towards medicine sharing) and outcome (medicine sharing behaviours) variables. Half of the study participants reported ever borrowing/lending medicines, and approximately a third of participants reported borrowing/lending in the past year. Modifiable risk factors associated with an increased risk of medicine borrowing behaviour were having more difficulty with accessing medicine ('access-related issue'), stronger 'emotional beliefs about borrowing', and greater 'concern about missing doses.' Greater 'concern for the wellbeing of others' and stronger 'beliefs about the benefits and safety of lending' were associated with an increased risk of medicine lending behaviour. Those with a higher 'perceived risk of harm' were less likely to borrow or lend medicines. This research expands the current knowledge of medicine sharing by examining underlying behavioural factors which predict sharing behaviours and that can be modified by interventions. This research suggests using multifaceted
Full Text Available Dams and reservoirs are useful systems in water conservancy projects; however, they also pose a high-risk potential for large downstream areas. Flood, as the driving force of dam overtopping, is the main cause of dam failure. Dam floods and their risks are of interest to researchers and managers. In hydraulic engineering, there is a growing tendency to evaluate dam flood risk based on statistical and probabilistic methods that are unsuitable for the situations with rare historical data or low flood probability, so a more reasonable dam flood risk analysis method with fewer application restrictions is needed. Therefore, different from previous studies, this study develops a flood risk analysis method for large dams based on the concept of total risk factor (TRF used initially in dam seismic risk analysis. The proposed method is not affected by the adequacy of historical data or the low probability of flood and is capable of analyzing the dam structure influence, the flood vulnerability of the dam site, and downstream risk as well as estimating the TRF of each dam and assigning corresponding risk classes to each dam. Application to large dams in the Dadu River Basin, Southwestern China, demonstrates that the proposed method provides quick risk estimation and comparison, which can help local management officials perform more detailed dam safety evaluations for useful risk management information.

The aim of this study was to determine the influence of menopause (hypoestrogenism) as a risk factor for oxidative stress. We carried out a cross-sectional study with 187 perimenopausal women from Mexico City, including 94 premenopausal (mean ± SD age, 44.9 ± 4.0 y; estrogen, 95.8 ± 65.7 pg/mL; follicle-stimulating hormone, 13.6 ± 16.9 mIU/mL) and 93 postmenopausal (mean ± SD age, 52.5 ± 3.3 y; estrogen, 12.8 ± 6.8 pg/mL; follicle-stimulating hormone, 51.4 ± 26.9 mIU/mL) women. We measured lipoperoxides using a thiobarbituric acid-reacting substance assay, erythrocyte superoxide dismutase and glutathione peroxidase activities, and the total antioxidant status with the Randox kit. An alternative cutoff value for lipoperoxide level of 0.320 μmol/L or higher was defined on the basis of the 90th percentile of young healthy participants. All women answered the Menopause Rating Scale, the Athens Insomnia Scale, and a structured questionnaire about pro-oxidant factors, that is, smoking, consumption of caffeinated and alcoholic beverages, and physical activity. Finally, we measured weight and height and calculated body mass index. The lipoperoxide levels were significantly higher in the postmenopausal group than in the premenopausal group (0.357 ± 0.05 vs 0.331 ± 0.05 μmol/L, P = 0.001). Using logistic regression to control pro-oxidant variables, we found that menopause was the main risk factor for oxidative stress (odds ratio, 2.62; 95% CI, 1.35-5.11; P menopause rating score, insomnia score, and lipoperoxides, and this relationship was most evident in the postmenopausal group (menopause scale, r = 0.327 [P = 0.001]; insomnia scale, r = 0.209 [P < 0.05]). Our findings suggest that the depletion of estrogen in postmenopause could cause oxidative stress in addition to the known symptoms.

To characterize the presence of hoarseness and the risk factors in male and female university teachers in private institutions in the city of São Paulo, Brazil. Cross-sectional survey. Voice self-evaluation forms prepared by the Brazilian Ministry of Labor were administered to 846 university teachers in a private institution in the city of São Paulo, Brazil. Prevalence of hoarseness in the sample is 39.6%. Percentage of hoarseness is higher in females (51.8%) than in males (32.6%). Comparing hoarseness and time of teaching, it was observed that the percentage of hoarseness is lower in a time shorter or equal to 1 year, and it is higher in a time between 10 and 20 years. Percentage of hoarseness is lower in the maximum workload of one to three class hours per day compared with the other workloads. Percentage of hoarseness is lower when the maximum number of students per classroom is less than 30 than when it is between 101 and 150 students. Other factors like in terms of noise and sound competition, air pollution, and in terms of causing stress and anxiety, besides habits and style/quality of life are related to the presence of hoarseness. University teachers show high percentage of hoarseness. Factors, such as time of teaching, females, work organization, workplace, in terms of noise and sound competition, air pollution, and in terms of causing stress and anxiety, besides habits and style/quality of life, are related to the presence of hoarseness in this group.

Full Text Available The goal of this study was to investigate the dynamics of decision making under risk. In three experiments this dynamics have been explored with respect to probability of outcome and with respect to frame, i.e. the way the outcomes of the alternatives have been specified. The process of decision making was explored within a framework of expected utility and Prospect theory. The outcomes of alternatives as well as their probabilities were quantitatively specified (so that the expected value of a risk alternative was equal to the value of a non-risk alternative. The results of experiments indicate that the attitude towards risk (risk-proneness vs. risk-averseness depends on the outcome probability and the way the outcomes were specified (i.e. positive/negative frame. It was also demonstrated that content strongly affects the choices made in decision making. This outcome is somewhat unexpected and requires additional empirical evaluation.

There is a significant gender imbalance on financial trading floors. This motivated us to investigate gender differences in financial risk taking under pressure. We used a well-established approach from behavior economics to analyze a series of risky monetary choices by male and female participants with and without time pressure. We also used second to fourth digit ratio (2D:4D) and face width-to-height ratio (fWHR) as correlates of pre-natal exposure to testosterone. We constructed a structural model and estimated the participants' risk attitudes and probability perceptions via maximum likelihood estimation under both expected utility (EU) and rank-dependent utility (RDU) models. In line with existing research, we found that male participants are less risk averse and that the gender gap in risk attitudes increases under moderate time pressure. We found that female participants with lower 2D:4D ratios and higher fWHR are less risk averse in RDU estimates. Males with lower 2D:4D ratios were less risk averse in EU estimations, but more risk averse using RDU estimates. We also observe that men whose ratios indicate a greater prenatal exposure to testosterone exhibit a greater optimism and overestimation of small probabilities of success.

While some evidence suggests that adverse experiences in childhood contribute to its development, specific evidence has been equivocal.Methods: A total of 36 patients with fibromyalgia from the greater New York area were recruited and surveyed using the Centers for Disease Control's Behavioral Risk Factor Surveillance System survey, and questions from the section on adverse childhood experiences were administered. The results were compared to those obtained from over 400,000 people surveyed by the Centers for Disease control each year, and were monitored for statistically significant differences.Results: A statistically significant difference was noted among the control group, suggesting that individuals reported growing up with someone who was depressed when the respondents were between the ages of 0 and 18 years old. Moreover, respondents reported that they were hit by their parents in some way, were insulted or cursed at by their parents, and had been forced to have sex with someone at least 5 years older than them or with an adult. No correlation was found with the following variables and the development of fibromyalgia: growing up with divorced or separated parents; growing up with someone sentenced to serve time in jail; or having parents that abused each other. Additionally, statistically significant differences were found for the following categories: lack of emotional support; life dissatisfaction; fair or poor health; physical, mental or emotional disability; and being divorced or not married.Discussion: Using this well-validated survey, it became clear that at least six specific adverse childhood

Full Text Available Sustainable supply chain network design is a rich area for academic research that is still in its infancy and has potential to affect supply chain performance. Increasing regulations for carbon and waste management are forcing firms to consider their supply chains from ecological and social objectives, but in reality, however, facilities and the links connecting them are disrupted from time to time, due to poor weather, natural or manmade disasters or a combination of any other factors. Supply chain systems drop their sustainability objectives while coping with these unexpected disruptions. Hence, the new challenges for supply chain managers are to design an efficient and effective supply chain network that will be resilient enough to bounce back from any disruption and that also should have sufficient vigilance to offer same sustainability under a disruption state. This paper focuses on ecological sustainability, because an environmental focus in a supply chain system is more important and also links with other pillars of sustainability, as the products need to be produced, packed and transported in an ethical way, which should not harm social balance and the environment. Owing to importance of the considered issue, this paper attempts to introduce a network optimization model for a sustainable and resilient supply chain network by incorporating (1 sustainability via carbon emissions and embodied carbon footprints and (2 resilience by incorporating location-specific risks. The proposed goal programming (GP model optimizes the total cost, while considering the resilience and sustainability of the supply chain network.
Full Text Available Portfolio optimization with respect to different risk measures is of interest to both practitioners and academics. For there to be a well-defined optimal portfolio, it is important that the risk measure be coherent and quasiconvex with respect to the proportion invested in risky assets. In this paper we investigate one such measure—conditional capital at risk—and find the optimal strategies under this measure, in the Black-Scholes continuous time setting, with time dependent coefficients.

We report on an experimental study with real-world politicians. These political experts face political choice problems under risk and probability. Thus, we test the frequently observed violations of rational choice theory -the reference point effect, loss aversion, framing effects, and the common ratio effect- with experts from the field. Their choices violate expected utility theory. Nevertheless, they appear to be more rational and less risk averse (loving) in the domain of gains (losses) t...

In this paper, we investigate a minimum risk portfolio model under hybrid uncertainty when the profitability of financial assets is described by fuzzy random variables. According to Feng, the variance of a portfolio is defined as a crisp value. To aggregate fuzzy information the weakest (drastic) t-norm is used. We construct an equivalent stochastic problem of the minimum risk portfolio model and specify the stochastic penalty method for solving it.

This study explored the driving behaviors and crash risk of 768 drivers who were under administrative lifetime driver's license revocation (ALLR). It was found that most of the ALLR offenders (83.2%) were still driving and only a few (16.8%) of them gave up driving completely. Of the offenders still driving, 67.6% experienced encountering a police roadside check, but were not detained or ticketed by the police. Within this group, 50.6% continued driving while encountering a police check, 18.0% of them made an immediate U-turn and 9.5% of them parked and exited their car. As to crash risk, 15.2% of the ALLR offenders had at least one crash experience after the ALLR had been imposed. The results of the logistic regression models showed that the offenders' crash risk while under the ALLR was significantly correlated with their personal characteristics (personal income), penalty status (incarceration, civil compensation and the time elapsed since license revocation), annual distance driven, and needs for driving (working, commuting and driving kids). Low-income offenders were more inclined to have a crash while driving under the ALLR. Offenders penalized by being incarcerated or by paying a high civil compensation drove more carefully and were less of a crash risk under the ALLR. The results also showed there were no differences in crash risk under the ALLR between hit-and-run offences and drunk driving offences or for offenders with a professional license or an ordinary license. Generally, ALLR offenders drove somewhat more carefully and were less of a crash risk (4.3 crashes per million km driven) than legal licensed drivers (23.1 crashes per million km driven). Moreover, they seemed to drive more carefully than drivers who were under short-term license suspension/revocation which previous studies have found. Copyright © 2011 Elsevier Ltd.

Risk factors were studied in 123 children with limb reduction defects (LRD) from 118,265 consecutive births of known outcome during the period from 1979 to 1987 in the area which is covered by our registry of congenital malformations. For each case a control was studied. The LRD was localised and classified according to the EUROCAT guide for the description and classification of limb defects. The prevalence of LRD was 1.04 per thousand: 82.9% of the babies were liveborn, 13.0% were late spontaneous abortion or stillborn and termination was performed in 4.0% of the cases. The proportion of males was 0.55. The most common malformations in the 51.2% of children who had at least one other anomaly than LRD were associated cardiac, digestive and renal anomalies. The pregnancy with limb anomalies was more often complicated by oligohydramnios, polyhydramnios and threatened abortion but there were no differences in parental characteristics. However, 9.7% of marriages were consanguineous (P less than 0.01) and the incidence of LRD in first-degree relatives of the children with LRD was high. First-degree relatives also had more non-limb malformations than did those of controls.

Objective. To document the incidence of postinfusion phlebitis and to investigate associated risk factors. Design. Analysis of existing data set from a large randomized controlled trial, the primary purpose of which was to compare routine peripheral intravascular catheter changes with changing catheters only on clinical indication. Participants and Setting. Patients admitted to a large, acute general hospital in Queensland, Australia, and who required a peripheral intravenous catheter. Results. 5,907 PIVCs from 3,283 patients were studied. Postinfusion phlebitis at 48 hours was diagnosed in 59 (1.8%) patients. Fifteen (25.4%) of these patients had phlebitis at removal and also at 48 hours after removal. When data were analyzed per catheter, the rate was lower, 62/5907 (1.1%). The only variable associated with postinfusion phlebitis was placement of the catheter in the emergency room (P = 0.03). Conclusion. Although not a common occurrence, postinfusion phlebitis may be problematic so it is important for health care staff to provide patients with information about what to look for after an intravascular device has been removed. This trial is registered with ACTRN12608000445370. PMID:26075092

Amblyopia is the main cause for mostly monocular, impaired vision in childhood. Treatment and prevention of amblyopia is only effective during childhood. Ophthalmological screening of children does not yet exist in Germany. The prevalence of amblyopia in Germany is 5.6%, which is higher than in reports from studies in Australia; however, the prevalence of amblyopia is not comparable in these studies due to different definitions of amblyopia and the inclusion/exclusion criteria of the study cohorts. At present it is unknown at what age ophthalmological screening should be carried out to prevent amblyopia and the appropriate frequency of screening examinations. Amblyopia is a disorder of the visual cortex that is due to suppression and deprivation of one eye leading to unilateral visual impairment. Approximately 50% of cases of amblyopia are caused by anisometropia, 25% by strabismus and in every sixth person by a combination of both. Other causes, such as unilateral congenital cataracts are relatively rare. A variety of factors, such as ocular pathologies, premature birth, familial disposition and general diseases are associated with an increased risk for amblyopia.

Psychiatric comorbidities are common among patients with headache. These can compromise the quality of life of patients and may affect the result of treatment. No available systematic study concerning this problem has been conducted in Thailand. The study aimed to determine the prevalence and risk factors of psychiatric disorders in patients with headache in tertiary care facility. The study was conducted at the Headache Clinic, King Chulalongkorn Memorial Hospital in Bangkok, Thailand. One hundred and thirteen patients were enrolled. Diagnosis of headache was made based on International Classification of Headache Disorders II system. Mental disorders were assessed using Primary Care Evaluation of Mental Disorders. Other possible risk factors were extracted using significant physical symptoms count and accumulated risk for mental disorder. Of the 113 samples analyzed, the prevalence of depression, anxiety, and somatoform disorder was found to be 29.2%, 9.7%, and 27.4%, respectively. No definite relationship between headache types and mental disorders was observed. High number of significant physical complaints and health concerns significantly increased the risk for depression (OR = 4.6, 95% CI = 1.6 to 13.5) while the level of possible risk for mental disorder was associated with an increased risk for somatoform disorder (OR = 1.6, 95% CI = 1.2 to 2.2). The study confirmed high prevalence of psychiatric comorbidities in patients with headache. The results of this study will raise the awareness of physicians to possible underlying mental disorders in patients with headache and facilitate appropriate treatment or psychiatric referral. © 2011 American Headache Society.

Anthropogenic climate change possibly causes various impacts on human society and ecosystem. Here, we call possible damages or benefits caused by the future climate change as "climate risks". Many climate risks are closely interconnected with each other by direct cause-effect relationship. In this study, the major climate risks are comprehensively summarized based on the survey of studies in the literature using IPCC AR5 etc, and their cause-effect relationship are visualized by a "network diagram". This research is conducted by the collaboration between the experts of various fields, such as water, energy, agriculture, health, society, and eco-system under the project called ICA-RUS (Integrated Climate Assessment - Risks, Uncertainties and Society). First, the climate risks are classified into 9 categories (water, energy, food, health, disaster, industry, society, ecosystem, and tipping elements). Second, researchers of these fields in our project survey the research articles, and pick up items of climate risks, and possible cause-effect relationship between the risk items. A long list of the climate risks is summarized into ~130, and that of possible cause-effect relationship between the risk items is summarized into ~300, because the network diagram would be illegible if the number of the risk items and cause-effect relationship is too large. Here, we only consider the risks that could occur if climate mitigation policies are not conducted. Finally, the chain of climate risks is visualized by creating a "network diagram" based on a network graph theory (Fruchtman & Reingold algorithm). Through the analysis of network diagram, we find that climate risks at various sectors are closely related. For example, the decrease in the precipitation under the global climate change possibly causes the decrease in river runoff and the decrease in soil moisture, which causes the changes in crop production. The changes in crop production can have an impact on society by

To investigate the risk factors for postpartum urinary incontinence (UI) and its characteristics. This was a case-control study with 344 puerperal women (77 cases and 267 controls) with up to 90 days postpartum. In a single session, participants were given a questionnaire with sociodemographic and clinical data and two others that assessed urine leakage, leakage situations, and type of UI. Stress UI was present in 45.5% of the women, incidents of urine leakage several times a day in 44.2%, of which 71.4% were in small amounts and 57.1% when coughing or sneezing. In 70.1% of cases, UI began during pregnancy and remained through the postpartum period. After running a binary logistic regression model, the following factors remained in the final model: UI during pregnancy (OR 12.82, CI 95% 6.94 - 23.81, ppregnancy and remained through the postpartum period. Urinary incontinence during pregnancy, multiparity, gestational age at birth greater or equal to 37 weeks, and constipation were presented as risk factors.

A stress fracture represents the inability of the skeleton to withstand repetitive bouts of mechanical loading, which results in structural fatigue, and resultant signs and symptoms of localised pain and tenderness. Reports of stress fractures in female football players are not prevalent; however, they are probably under-reported and their importance lies in the morbidity that they cause in terms of time lost from participation. By considering risk factors for stress fractures in female football players it may be possible to reduce the impact of these troublesome injuries. Risk factors for stress fractures in female football players include intrinsic risk factors such as gender, endocrine, nutritional, physical fitness and neuromusculoskeletal factors, as well as extrinsic risk factors such as training programme, equipment and environmental factors. This paper discusses these risk factors and their implications in terms of developing prevention and management strategies for stress fractures in female football players.

The rising prevalence of obesity and diabetes cannot be fully explained by known risk factors, such as unhealthy diet, a sedentary lifestyle, and family history. This review summarizes the available studies linking persistent organic pollutants (POPs) to obesity and diabetes and discusses plausible underlying mechanisms. Increasing evidence suggest that POPs may act as obesogens and diabetogens to promote the development of obesity and diabetes and induce metabolic dysfunction. POPs are synthesized chemicals and are used widely in our daily life. These chemicals are resistant to degradation in chemical or biological processes, which enable them to exist in the environment persistently and to be bio-accumulated in animal and human tissue through the food chain. Increasingly, epidemiologic studies suggest a positive association between POPs and risk of developing diabetes. Understanding the relationship of POPs with obesity and diabetes may shed light on preventive strategies for obesity and diabetes.

Full Text Available The negative consequences of energy dense foods are well known, yet people increasingly make unhealthy food choices leading to obesity (i.e., risky decisions. The aims of this study were:  to compare performance in decision-making tasks under risk and under ambiguity between individuals with obesity, overweight and normal weight;  to examine the associations between body mass index (BMI and decision-making, and the degree to which these associations are modulated by reward sensitivity.Seventy-nine adults were recruited and classified in three groups according to their BMI: obesity, overweight and normal-weight. Groups were similar in terms of age, education and socio-economic status, and were screened for comorbid medical and mental health conditions. Decision-making under risk was measured via the Wheel of Fortune Task (WoFT and decision-making under ambiguity via the Iowa Gambling Task (IGT. Reward sensitivity was indicated by the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ.Individuals with obesity made riskier choices in the WoFT, specifically in choices with an expected value close to zero and in the propensity to risk index. No differences were found in IGT performance or SPSRQ scores. BMI was associated with risk-taking (WoFT performance, independently of reward sensitivity.Obesity is linked to a propensity to make risky decisions in experimental conditions analogous to everyday food choices.
In the context of hydrologic designs, robust assessment and communication of risk is crucial to ascertain a sustainable water future. Traditional methods for defining return period, risk or reliability assumes a stationary regime which may no longer be valid because of natural or man-made changes. Reformulations are suggested in recent literature to account for non-stationarity in the definition of hydrologic risk, as time evolves. This study presents a comparative analysis of design levels under non-stationarity based on time varying annual exceedance probabilities, waiting time of a hazardous event, number of hazardous events and probability of failure. A case study application is shown for peak streamflow in the flood-prone delta area of the Krishna River in India where an increasing trend in annual maximum flows are observed owing to persistent silting. Considerable disagreement is found between the design magnitudes of flood obtained by the different definitions of hydrologic risk. Such risk is also found to be highly sensitive to the assumed design life period and projections of trend in that period or beyond. Additionally, some critical points on the assumption of a deterministic non-stationary model for an observed natural process are also discussed. The findings highlight the necessity for a unifying framework for assessment and communication of hydrologic risk under transient hydro-climatic conditions. The concepts can also be extended to other applications such as regional hydrologic frequency analysis or development of precipitation intensity-duration-frequency relationships for infrastructure design.
Full Text Available INTRODUCTION: Osteoarthritis of the hip is a degenerative disease of hip unknown origin, with pain, stiffness and diminished joint function. AIM: determine the influence of the load of the hip joint during professional activity and BMI as risk factors for the hip osteoarthritis. MATERIAL AND METHOD: We analysed 148 patients. Patients were divided into two groups ( I group with osteoarthritis of the hip, II group without osteoarthritis of the hip. In all, performed diagnostic procedure: anamnesis, physical examination (estimate of walking and hip joint movement, laboratory blood test and urine test radiological examination and taking data on the height and weight to calculated BMI. We assessed the data that is related to the load of the hip joint during professional activities (mostly sitting work and mostly standing job with carrying load. Statistical analysis was done using the software package SPSS 14.0, Microsoft Office Word 2003. RESULTS: In the first group, average age was 67.76 years, with females prevailing (67.6%. In this group the larger body mass was noted (81.82 ± 12.18, with statistically significant difference (T-test 2.923, p<0.01; the average BMI was higher the average BMI was higher (30.18 ± 4.6, with statistically significant difference (T-test 3.832, p<0.01. This group had more overweight patients (87.7%,with statistically significant difference (Fisher test, p<0.01. In I group 62,2% of patients were doing hard physical work (standing job with repeated carrying load and we found statistically significant difference between groups (Fisher test p<0,01. CONCLUSION: Patients with osteoarthritis of the hip had a higher body weight, higher BMI. Also we found the influence of hard physical labor at work, and they were performed mostly standing job with carrying load.

Diabetes mellitus has been a well-known risk factor for TB in the past. The global convergence of the accelerating type 2 DM pandemic, high TB prevalence and drug-resistant TB during the past couple of decades has become a serious challenge to clinicians worldwide. Over the past few years, some studies have shown that the treatment failure rate is higher in TB patients with DM as comorbidity. Moreover, there is significant association between DM an MDR-TB. There is higher chance of TB bacilli persistence to be present in sputum of pulmonary TB patient with DM than TB-only patient after 5 months treatment, and this persistence made it necessary for more longer treatment. Presence of DM in TB patients cause a longer period for sputum conversion, therefore it may become a major cause of poor treatment outcome in TB patients. Previous studies showed that a major mechanism for the emergence of drugs resistance in TB bacilli is random mutation in the bacterial genome and the pressure of selection by anti-TB drugs. Pulmonary TB in diabetic patients usually show higher mycobacterial loads at the initiation of treatment, hence they may have higher chance of bacillary mutation and the emergence of MDR-TB with the presenting of higher bacterial loads, longer treatment is needed to clear the bacteria. Therefore, it is not suprising that a higher chance of MDR-TB patients could be find in those patients. A pharmacokinetic study noted that plasma levels of rifampicin were 53% lower in TB patients with diabetes, which might affect treatment outcomes. Inadequate immune respons of the host may also be important in this negative effect of diabetes. Depressed production of IFN-γ in diabetic patients is related to decreasing immune response to TB infection. Reduction of IL-12 response to mycobacterial stimulation in leukocytes from TB with diabetic patients suggest a compromise of innate immune response.

Objective: To find out the frequency of abdominal wound dehiscence (AWD) in a tertiary care hospital and the assessment of associated risk factors. Subjects and Methods: This study was carried out on 406 patients who underwent laparotomy for intra peritoneal procedure and complied with inclusion criteria. Demographic features were recorded and any complications documented. Results: Out of a total of 406 patients, 32 showed wound dehiscence giving an over all frequency of 7.8%. The male to female ratio was 2.8:1. The frequency was greater in males than in females. Majority patients suffered from an underlying malignancy. Malignant intestinal obstruction was the leading cause of wound dehiscence. Forty three patients had hypoalbuminemia(serum albumin <35 gm/l) and 09 of them had AWD. Emergency surgery showed a higher frequency of AWD(12.5%), as compared to elective surgery (18/143 and 14/263 respectively). Wound infection was a major contributor to AWD as out of 406, 76 patients developed infection and then 21 manifested AWD. Older age was also associated with greater frequency. The overall mortality of AWD in this study was 28.1 %. Conclusion: AWD still continues to be major post operative complication, with a high morbidity and mortality. The significant risk factors in this study were age more than 55 years, male gender, underlying malignancy, wound infection, jaundice, use of steroids, emergency surgery, uraemia and technique of closure.

People often have to make decisions under uncertainty-that is, in situations where the probabilities of obtaining a payoff are unknown or at least difficult to ascertain. One solution to this problem is to infer the probability from the magnitude of the potential payoff and thus exploit the inverse relationship between payoffs and probabilities that occurs in many domains in the environment. Here, we investigated how the mind may implement such a solution: (1) Do people learn about risk-reward relationships from the environment-and if so, how? (2) How do learned risk-reward relationships impact preferences in decision-making under uncertainty? Across three experiments (N = 352), we found that participants can learn risk-reward relationships from being exposed to choice environments with a negative, positive, or uncorrelated risk-reward relationship. They were able to learn the associations both from gambles with explicitly stated payoffs and probabilities (Experiments 1 & 2) and from gambles about epistemic events (Experiment 3). In subsequent decisions under uncertainty, participants often exploited the learned association by inferring probabilities from the magnitudes of the payoffs. This inference systematically influenced their preferences under uncertainty: Participants who had been exposed to a negative risk-reward relationship tended to prefer the uncertain option over a smaller sure option for low payoffs, but not for high payoffs. This pattern reversed in the positive condition and disappeared in the uncorrelated condition. This adaptive change in preferences is consistent with the use of the risk-reward heuristic.

Full Text Available This study explores how audit firms in Jordan deal with the presence of fraud risk factors in audit clients. In doing so, the study seeks to explore which fraud risk factors are more important to Jordanianauditors, and how Jordanian auditors consider modifying their audit programmes when fraud risk factors are present in clients. The study uses a structured questionnaire that was administered to seniorlevel auditors in the largest Jordanian audit firms. The findings show that almost all of the 20 fraud risk factors included in the questionnaire were only slightly important (if not unimportant, a finding that is arguably alarming. The perceived importance of modifying the audit programme in the presence of each fraud risk factor was related to the perceived importance of the fraud risk factor itself. However, changes in the nature and extent of audit procedures were more important than changes in the timing of the procedures or the members of the audit team. The most important fraud risk factors were related to the characteristics of management and its attitude towards the audit, while the least important fraud risk factors were related to the difficulties in the client’s financial performance. Factor analysis found that the fraud risk factors could be classified into four separate groups. Possible interpretations of the findings were discussed, such as considering the Jordanian business environment characteristics, and the findings were compared to those of extant international studies.

Objective: This study sought to assess the relationship between correlative comprehension risk factors and coronary arterial disease and to build up a simple mathematical model to evaluate the extension of coronary artery lesion in patients with stable angina. Methods: A total of 1024 patients with chest pain who underwent coronary angiography were divided into CAD group(n=625)and control group(n=399) based on at least one significant coronary artery narrowing more than 50% in diameter. Independent risk factors for CAD were evaluated and multivariate logistic regression model and receiver-operating characteristic(ROC) curves were used to estimate the independent influence factor for CAD and built up a simple formula for clinical use. Results: Multivariate regression analysis revealed that UACR > 7.25 μg/mg(OR=3.6; 95% CI 2.6-4.9; P 20 mmol/L(OR=3.2; 95% CI 2.3-4.4; P 2 (OR=2.3; 95% CI 1.4-3.8; P 2.6 mmol/L (OR 2.141; 95% CI 1.586-2.890; P 7.25 μg/mg + 1.158 x hsCRP > 20 mmol/L + 0.891 GFR 2 + 0.831 x LVEF 2.6 mmol/L + 0.676 x smoking history + 0.594 x male + 0.459 x diabetes + 0.425 x hypertension). Area under the curve was 0.811 (P < 0.01), and the optimal probability value for predicting severe stage of CAD was 0.977 (sensitivity 49.0%, specificity 92.7% ). Conclusions: Risk factors including renal insufficiency were the main predictors for CAD. The logistic regression model is the non-invasive method of choice for predicting the extension of coronary artery lesion in patients with stable agiana. (authors)

Previous studies suggest that chronic stress may induce immune system malfunction and a broad range of adverse health outcomes; however, the underlying pathways for this relationship are unclear. Our study aimed to elucidate this question by examining the relationship between parental cardiovascular risk factors including systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), and waist-to-hip ratio (WHR) and maternal psychological stress score (MPSS) relative to the severity of the child's food allergy (FA) and number of affected children. SBP, DBP, BMI, and WHR were measured and calculated at the time of recruitment by trained nurses. MPSS was obtained based on self-report questionnaires covering lifestyle adjustments, perceived chronic stress, and quality of life. General linear models examined whether caregiver chronic stress was associated with FA. For mothers with children under age 5 years, SBP, DBP and number of affected children had strong and graded relationships with severity of the child's FA. MPSS was also significantly and positively associated with child FA severity (P parent. This was also the case for paternal SBP, DBP, and number of affected children of any age. There is a strong and graded link between cardiovascular risk and perceived stress in mothers of food-allergic children under age 5. Findings may have important implications for family-centered care of FA, may generalize to caregivers of children with chronic conditions, and extend the literature on allostatic load.

Since first reported in the late 1970s, there has been a steady but dramatic increase in the worldwide prevalence of hyperthyroidism in cats. It is now regarded as the most common feline endocrine disorder, with diabetes mellitus coming a close second. Not only is there evidence for an increased worldwide prevalence of feline hyperthyroidism, but also for geographical variation in the prevalence of the disease. Despite its frequency, the underlying cause(s) of this common disease is or are not known, and therefore prevention of the disease is not possible. Due to the multiple risk factors that have been described for feline hyperthyroidism, however, it is likely that more than one factor is involved in its pathogenesis. Continuous, lifelong exposure to environmental thyroid-disruptor chemicals or goitrogens in food or water, acting together or in an additive fashion, may lead to euthyroid goitre and ultimately to autonomous adenomatous hyperplasia, thyroid adenoma and hyperthyroidism. This review aims to summarise the available published evidence for the changes observed in the worldwide prevalence of the disease, as well as risk factors that may contribute to development of hyperthyroidism in susceptible cats.

Full Text Available Acute kidney injury (AKI in the newborn is a common problem in the neonatal intensive care unit with many underlying factors such as asphyxia, respiratory distress syndrome (RDS, and urogenital anomalies. The aim of this study is to highlight possible risk factors and profile of neonates developing AKI in the Neonatal Intensive Care Unit (NICU of Cairo University Pediatric Hospital. The study was carried out on 90 neonates (30 patients and 60 controls, among neonates admitted to NICU. The study was done over two months, from January 2015 to March 2015. Our study showed that sepsis was detected in 53.3%, prematurity in 46.67%, RDS in 43.3%, congenital heart disease in 20%, and hypoxic-ischemic encephalopathy in 6.67% of patients. Maternal illness and low body temperature were both significant risk factors of AKI in neonates. History of maternal illness, low body temperature, sepsis, prematurity, and respiratory distress can contribute to the development of AKI in neonates.

Risk perception is one of important subjects in management psychology and cognitive psychology. It is of great value in the theory and practice to investigate the societal hazards that the public cares a lot especially in Socio-economic transition period. A survey including 30 hazards and 6 risk attributes was designed and distributed to about 2, 485 residents of 8 districts, Beijing. The major findings are listed as following: Firstly, a scale of societal risk perception was designed and 2 factors were identified (Dread Risk & Unknown Risk). Secondly, structural equation model was used to analyze the influence factors and mechanism of societal risk perception. Risk preference, government support and social justice could influence societal risk perception directly. Government support fully moderated the relationship between government trust and societal risk perception. Societal risk perception influenced life satisfaction, public policy preferences and social development belief.
A cross-sectional study of factors underlying the risk of female nurses' suffering abuse by their partners Estudio transversal sobre factores de riesgo de sufrir violencia por compañero íntimo en la mujer enfermera Estudo transversal sobre fatores de risco de violência por parceiro íntimo entre enfermeiras
Full Text Available This study aimed to identify factors underlying the risk of suffering abuse by a partner. A cross-sectional study of 622 female nurses was accomplished, randomly chosen at their place of work, at a hospital and health centers. We used a self-administered validated questionnaire that covered psychological, physical and sexual abuse, complemented by a set of sociodemographic questions. The nurses at most risk of being abused by their partners were those who supported their family by their own salary (Odds Ratio: 2.41 [0.63-9.15], those who lived with dependents (Odds Ratio: 4.27 [1.43-2.78] and had a partner from social class IIIa (Odds Ratio: 2.62 [1.37-5.00]. The data appear to indicate financial independence as a risk factor for this type of abuse.Se tuvo por objetivo investigar los factores de riesgo relacionados al maltrato por compañero íntimo.

The observation of the locomotor and exploratory behaviors of rodents in an open field is one of the most fundamental methods used in the field of behavioral pharmacology. A variety of behaviors can be recorded automatically and can readily generate a multivariate pattern of pharmacological effects. Nevertheless, the optimal ways to characterize observed behaviors and concomitant drug effects are still under development. The aim of this study was to extract meaningful behavioral factors that could explain variations in the observed variables from mouse exploration. Behavioral data were recorded from male C57BL/6J mice (n=268) using the Behavioral Pattern Monitor (BPM). The BPM data were subjected to the exploratory factor analysis. The factor analysis extracted four factors: activity, sequential organization, diversive exploration, and inspective exploration. The activity factor and the two types of exploration factors correlated positively with one another, while the sequential organization factor negatively correlated with the remaining factors. The extracted factor structure constitutes a behavioral model of mouse exploration. This model will provide a platform on which one can assess the effects of psychoactive drugs and genetic manipulations on mouse exploratory behavior. Further studies are currently underway to examine the factor structure of similar multivariate data sets from humans tested in a human BPM. Copyright © 2012 Elsevier B.V. All rights reserved.

In many parts of the world, drought hazard is becoming more frequent and severe due to climate change and human activities. It is crucial to monitor and assess drought conditions, especially for decision making support in agriculture sector. The vegetation index (VI) decreases, and the land surface temperature (LST) increases when the vegetation is under drought stress. Therefore both of these remotely sensed indices are widely used in drought monitoring and assessment. Temperature-Vegetation Dryness Index (TVDI) is obtained by establishing the feature space of the normalized difference vegetation index (NDVI) and LST, which reflects agriculture dry situation by inverting soil moisture. However, these indices only concern the natural hazard-causing factors. Our society is a complex large-scale system with various natural and social elements. The drought risk is the joint consequence of hazard-causing factors and hazard-affected bodies. For example, as the population increases, the exposure of the hazard-affected bodies also tends to increase. The high GDP enhances the response ability of government, and the irrigation and water conservancy reduces the vulnerability. Such characteristics of hazard-affected bodies should be coupled with natural factors. In this study, the 16-day moderate-resolution imaging spectroradiometer (MODIS) NDVI and LST data are combined to establish NDVI-Ts space according to different land use types in Yunnan Province, China. And then, TVDIs are calculated through dry and wet edges modeled as a linear fit to data for each land cover type. Next, the efforts are turned to establish an integrated drought assessment index of social factors and TVDI through ascertaining attribute weight based on rough sets theory. Thus, the new CDI (comprehensive drought index) recorded during spring of 2010 and the spatial variations in drought are analyzed and compared with TVDI dataset. Moreover, actual drought risk situation in the study area is given to

To determine the frequency, risk factors and pattern of urinary complaints during pregnancy. A descriptive study was conducted in the Obstetric and Gynaecology Department of Isra University Hospital, Hyderabad from 1st January to 30th August 2008. Total 232 women were selected to ascertain the frequency and pattern of urinary symptoms as well as the risk factors of urinary tract infection (UTI) such as age, parity, education, past history of UTI and haemoglobin among women attending an antenatal clinic. All pregnant women irrespective of age, parity and gestational age were included, while women with known underlying renal pathology, chronic renal disease, renal transplant, diabetes or taking immunosuppressant therapy were excluded. Informed consent was taken and data collected on a self designed proforma. All the women underwent complete examination of urine. Dipstick test was performed on midstream urine and urine was cultured incase of positive dipstick test and women with urinary symptoms. Data was analyzed on SPSS version 11. Odds ratio and 95% confidence interval were calculated among the categorical parameters by applying the Fisher's exact test. Out of 232 women, 108(46.5%) reported urinary symptoms which were due to pregnancy induced changes on urinary system as no growth was obtained on urine culture, while 10 (4.3%) were due to underlying UTI. Most common urinary symptom in these women was abnormal voiding pattern 85 (40.3%) followed by irritative symptoms and voiding difficulties. Illiteracy, history of sexual activity, low socioeconomic (monthly income UTI and multiparity were found to be risk factors for UTI in these women. On complete urine examination, 222 (95.6%) patients either did not reveal any pus cells or had less than 5 WBC/HPF. Out of 108 cultures, only 10 (4.3%) specimens showed growth.
