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.

Central Asia has experienced a rapid increase in HIV. HIV interventions and prevention programmes are needed that adequately appreciate and account for the ways that ongoing cultural, political, and economic changes in this region affect HIV risk reduction efforts. Drawing on relevant literature, this paper provides a contextual foundation to better understand the impact of context on HIV risk behaviour in the countries of Central Asia and to begin the conversation on the contextual factors of Islam and polygamy.

Background Patients at higher than average risk of heritable cancer may process risk information differently than the general population. However, little is known about clinical, demographic, or psychosocial predictors that may impact risk perception in these groups. The objective of this study was to characterize factors associated with perceived risk of developing cancer in groups at high risk for cancer based on genetics or family history. Methods We searched Ovid MEDLINE, Ovid Embase, Ovid PsycInfo, and Scopus from inception through April 2009 for English-language, original investigations in humans using core concepts of "risk" and "cancer." We abstracted key information and then further restricted articles dealing with perceived risk of developing cancer due to inherited risk. Results Of 1028 titles identified, 53 articles met our criteria. Most (92%) used an observational design and focused on women (70%) with a family history of or contemplating genetic testing for breast cancer. Of the 53 studies, 36 focused on patients who had not had genetic testing for cancer risk, 17 included studies of patients who had undergone genetic testing for cancer risk. Family history of cancer, previous prophylactic tests and treatments, and younger age were associated with cancer risk perception. In addition, beliefs about the preventability and severity of cancer, personality factors such as "monitoring" personality, the ability to process numerical information, as well as distress/worry also were associated with cancer risk perception. Few studies addressed non-breast cancer or risk perception in specific demographic groups (e.g. elderly or minority groups) and few employed theory-driven analytic strategies to decipher interrelationships of factors. Conclusions Several factors influence cancer risk perception in patients at elevated risk for cancer. The science of characterizing and improving risk perception in cancer for high risk groups, although evolving, is still

Full Text Available Background. Tuberculosis (TB notification in South Africa has increased six-fold over the past two decades, mainly because of the HIV epidemic. Objectives. To describe the sociodemographic and outcome characteristics of TB patients, and to identify risk factors associated with TB treatment outcomes stratified by HIV status. Methods. A cross-sectional study was used to analyse data from the Cape Town Metro East geographical service area (GSA electronic TB register (ETR.Net, including adult patients aged ≥15 years who initiated TB treatment between 1 July 2011 and 30 June 2012. Results. TB case notification in the GSA was 922 per 100 000 population. Of the 12 672 TB patients registered, 50.5% were co-infected with HIV. The death rate in co-infected patients was 5.4% v. 2.8% in HIV-negative patients, the rate of treatment success 66.6% v. 73.5%, and the rate of unfavourable treatment outcome 28.1% v. 23.7%. The Khayelitsha subdistrict had the highest proportion of TB burden (37.0% and co-infection (47.6%. Fourteen percent of patients had extrapulmonary TB, 65.9% of whom were co-infected with HIV. In the multivariate analysis, HIV infection (relative risk (RR 1.2, retreatment (RR 1.4 and sputum smear microscopy not done (RR 1.4 were significantly associated with unfavourable treatment outcome. The Eastern (RR 0.9 and Northern (RR 0.7 subdistricts were less likely to have unfavourable outcomes compared with Khayelitsha. In the stratified analysis, retreatment and smear not done were significant risk factors for an unfavourable treatment outcome in both co-infected and HIV-negative patients. Conclusions. The burdens of both TB and co-infection were high in this community, although HIV prevalence varied. Mortality was higher and treatment completion lower in co-infected patients than in those who were HIV-negative. Co-infection, previous TB treatment and smear not done were significant risk factors for an unfavourable outcome in all patients.

In this study, we introduce the first twin study in Turkey, focusing on smoking behavior, and laying the foundation to register all twins born in Turkey for research purposes. Using Turkish twins will contribute to our understanding of health problems in the context of cultural differences. We assessed 309 twin pairs (339 males and 279 females) aged between 15 and 45 years living in the Kırıkkale and Ankara regions of Turkey, and administered a health and lifestyle interview that included questions about smoking status and smoking history. We analyzed the data using descriptive statistics, t-tests, chi-square tests, and bivariate and multivariate clustered logistic regression. In addition, we fit bivariate Structural Equation Models (SEM) to determine contributions of latent genetic and environmental factors to smoking outcomes in this sample. One hundred seventy-eight participants (28.8%) were identified as smokers, smoking every day for a month or longer, of whom 79.2% were males and 20.8% were females. Mean values for number of cigarettes per day and the Fagerstrom Test of Nicotine Dependence (FTND; Fagerstrom, 1978) score were higher in males than in females, and age of onset was earlier in males. There was a significant positive correlation between the FTND score and number of cigarettes smoked per day, and a significant negative correlation between both variables and age at onset of smoking. Our study showed that gender, presence of a smoking twin in the family, age, alcohol use, marital status, daily sports activities, and feeling moody all played a significant role in smoking behavior among twins. The twin analysis suggested that 79.5% of the liability to FTND was influenced by genetic factors and 20.5% by unique environment, while familial resemblance for smoking initiation was best explained by common environmental factors. Marked differences in the prevalence of smoking behavior in men versus women were observed for the Turkish population. Genetic
Full Text Available It is known in the literature that the incidence and prevalence of suicide and attempted suicide in psychiatric patients is significantly higher than in the general population. The paper examined risk factors for suicidal behavior in the category of admitted patients hospitalized with the diagnosis of sleep disorders and affective (Unipolar resp. Bipolar depression. Study activated by 80 patients, 40 in both diagnostic groups received treatment at the Special Psychiatric Hospital in Gornja Toponica near Nis. The work methodology used are: psychiatric interview, Hamilton Depression Rating Scale (HAMD, and the C-SSRS (Columbia-Suicide Severity Rating Scale- assessment tool that assesses suicidal ideation and behavior. The study results show that there is a relationship between suicidal behavior (suicide attempts and suicidal ideation and the diagnosis of bipolar affective disorder, positive history of previous suicide attempts, so that these factors are stronger, to the degree of suicidality higher. On this sample, clearly suicidal behavior, with the same purpose, intensity of suicidal thoughts and medical impairment after suicide attempts were significantly more frequent in patients with Bipolar Affective Disorder in the depressive phase of the illness. Patients with a previous suicide attempt, and poor personal and social circumstances had a higher rate of attempted suicide.
Stearic acid has been claimed to be prothrombotic. Elevated plasma factor VII coagulant activity (FVIIc) may raise the risk of coronary thrombosis in the event of plaque rupture. Fibrinogen, an acute-phase protein, is necessary for normal blood clotting; however, elevated levels of fibrinogen increase the risk of coronary heart disease (CHD). Here I report the results of three controlled, human dietary intervention studies, which used a randomized crossover design to investigate the hemostatic effects of stearic acid-rich test diets in healthy young men. A diet high in stearic acid (shea butter) resulted in a 13% lower fasting plasma FVIIc than a high palmitic acid diet, and was 18% lower than a diet high in myristic and lauric acids (P = 0.001) after 3 wk of intervention. The stearic acid-rich test fat increased plasma fibrinogen concentrations slightly compared with the myristic-lauric acid diet (P < 0.01). When investigating the acute effects of fatty meals, those high in stearic acid (synthesized test fat) resulted in a smaller postprandial increase in FVII than those high in trans and oleic FA, indicating a smaller increase in activated FVII after ingesting stearic acid compared with fats high in monounsaturated FA, probably caused by lower postprandial lipemia. Thus, the present investigations did not find dietary stearic acid to be more thrombogenic, in either fasting effects compared with other long-chain FA, or in acute effects compared with dietary unsaturated FA, including trans monounsaturated FA. The slightly increased effect on fasting plasma fibrinogen may be biologically insignificant, but it should be investigated further.
Full Text Available Road traffic accidents (RTAs are becoming a major problem around the world, incurring enormous losses of human and economic resources. Recent reports from the World Health Organization (WHO reveal that each year more than 1.25 million people are killed and 50 million are injured in road traffic accidents worldwide. In Saudi Arabia, statistics show that at least one traffic accident occurs every minute, causing up to 7,000 deaths and over 39,000 injuries annually. In this study, the main causes of RATs in the province of Hail are examined. The data was collected through the use of a survey which was developed to evaluate the effect of influencing parameters on RTA rate. The results show that 67% of RTAs result from human factors, 29% from road conditions and 4% from vehicle defects. Excessive speed and violation of traffic rules and regulations were found to be the main causes of RATs. Low rates of compliance with speed limit signs and seat-belt regulations were also observed. These findings highlight the need of strengthening effective traffic law enforcement alongside with improving traffic safety and raising public awareness.

To analyze the influence of highly active antiretroviral treatment (HAART) on risk factors for perinatal transmission of human immunodeficiency virus (HIV). A prospective cohort study was performed between HIV pregnant women under HAART therapy and without treatment. The maternity hospital 'La Fe' in Valencia, Spain. Five hundred HIV-positive pregnant women. Known maternal and obstetrical perinatal risk factors were analyzed by univariate and multivariate methods (logistic regression). The influence of HAART on the risk factors was evaluated independently to determine whether there was a modulation in perinatal HIV transmission. Known perinatal risk factors were found not to have any significant influence on perinatal HIV transmission in women under HAART therapy. Vertical transmission risk decreased significantly from 18.2% without treatment to 8.6% with mono/dual therapy and 0.6% with HAART. A CD4+ cell count below 500 cell/microl, intrapartum use of invasive procedures, rupture of membranes >six hours, labor length >five hours, and birthweight were the significant risk factors associated to vertical HIV transmission and elective cesarean section. Antiretroviral treatment administered during delivery was a protective factor in HIV pregnant women before HAART therapy. HAART therapy reduces the influence of the perinatal risk factors on vertical HIV transmission.

Background In recent years, high-risk sexual behaviors due to their negative consequences both for the individual and society have received more attention than other high-risk behaviors. Objective The aim of this study was to review the influencing factors of high-risk sexual behaviors among young people from an ecological point of view. Methods This review was conducted through searching databases including PubMed, Web of Science, Scopus, Google Scholar and the Cochrane Library with keywords such as sexual risk-taking behavior, high-risk sex, unprotected sex and unsafe sex. The relevant papers published between 1995 and 2016 were extracted. After reviewing the abstract and full text of the articles, 45 papers were used to write this article. Results From an ecological theory approach, factors which influence high-risk sexual behaviors are divided into three categories - the microsystem, the mesosystem and the macrosystem. The microsystem includes factors such as age, gender, race, marital status, place of residence, religion, level of education, personality traits, psychological problems, childhood experiences, body image and coincidence of high-risk behaviors; the mesosystem includes factors such as family structure, peers and sex education; in the macrosystem, the impact of culture and traditions of the society, economic status and the media are presented. Conclusion Given that high-risk sexual behaviors often have multiple causes, it seems that health policymakers must consider multi-dimensional interventions to influence high-risk sexual behaviors based on the ecological approach.

Full Text Available This research seeks to study the factors that enhance or preclude owners of SMEs in Ghana in making risk management decisions. The study was conducted with managers of SMEs in four regions in Ghana. The researchers adopted a quantitative approach and employed STATA 10 and SPSS version 20 in the analysis. Stratified and simple random sampling techniques were used to select the sample units. The probit model was used in the analysis of data. A total of 447 SMEs were sampled for the study, with at least 111 from each of the selected regions. The probit results show that the demographic factors indicate a positive influence on the likelihood that managers will take risk management decisions. All of the business related demographic factors are significant at various levels and positive, except for risk-loving. The economically related factors, such as the estimated amount at risk, the estimated cost of risk management and the estimated total monthly income after tax all have a positive influence on risk management decision making. However, government and tax policies are perceived to negatively influence risk management decisions by managers. We recommend that institutions working closely with SMEs acquire the expertise to train the managers of SMEs on risk management practices.

Many countries are confronting climate change that threatens agricultural production and farmers' lives. Farmers' perceived risks of climate change and factors influencing those perceived risks are critical to their adaptive behavior and well-planned adaptation strategies. However, there is limited understanding of these issues. In this paper, we attempt to quantitatively measure farmers' perceived risks of climate change and explore the influences of risk experience, information, belief in climate change, and trust in public adaptation to those perceived risks. Data are from structured interviews with 598 farmers in the Mekong Delta. The study shows that perceived risks to production, physical health, and income dimensions receive greater priority while farmers pay less attention to risks to happiness and social relationships. Experiences of the events that can be attributed to climate change increase farmers' perceived risks. Information variables can increase or decrease perceived risks, depending on the sources of information. Farmers who believe that climate change is actually happening and influencing their family's lives, perceive higher risks in most dimensions. Farmers who think that climate change is not their concern but the government's, perceive lower risks to physical health, finance, and production. As to trust in public adaptation, farmers who believe that public adaptive measures are well co-ordinated, perceive lower risks to production and psychology. Interestingly, those who believe that the disaster warning system is working well, perceive higher risks to finance, production, and social relationships. Further attention is suggested for the quality, timing, and channels of information about climate change and adaptation.

Full Text Available Background: Substantial empirical research has shown conflicting results regarding the influence of organizational external factors on construction risk management, suggesting the necessity to introduce a moderator into the study. The present research confirmed whether rules and regulations matter on the relationships between organizational external factors and construction risk management. Methods: Based on discouragement and organizational control theory, this research examined the effects of organizational external factors and rules and regulations on construction risk management among 238 employees operating in construction companies in Abuja and Lagos, Nigeria. A personally administered questionnaire was used to acquire the data. The data were analyzed using partial least squares structural equation modeling. Results: A significant positive relationship between organizational external factors and construction risk management was asserted. This study also found a significant positive relationship between rules and regulations and construction risk management. As anticipated, rules and regulations were found to moderate the relationship between organizational external factors and construction risk management, with a significant positive result. Similarly, a significant interaction effect was also found between rules and regulations and organizational external factors. Implications of the research from a Nigerian point of view have also been discussed. Conclusion: Political, economy, and technology factors helped the construction companies to reduce the chance of risk occurrence during the construction activities. Rules and regulations also helped to lessen the rate of accidents involving construction workers as well as the duration of the projects. Similarly, the influence of the organizational external factors with rules and regulations on construction risk management has proven that most of the construction companies that implement the

Previous studies have suggested that risk factors for ischaemic vascular disease, such as cigarette smoking, hypertension and hyperlipidaemia, can also be considered risk factors for the development of idiopathic sudden sensorineural hearing loss (ISSNHL). In this study, we have evaluated the hypothesis that these factors can influence hearing threshold recovery in patients affected by ISSNHL. A total of 141 subjects who suffered an episode of ISSNHL were included. All subjects were assessed with tonal audiometry, auditory brainstem responses and MRI to exclude retrocochlear pathology. Hearing tests were conducted at ISSNHL onset (t = 0) and after 30 days. Patients were divided into three classes according to the presence/absence of one or more cardiovascular risk factors including: history of smoking, total serum cholesterol/triglycerides, history of hypertension and diabetes mellitus. Values of hearing threshold recovery were estimated and comparisons were conducted across the three risk factor classes. 75% of patients affected by ISSNHL showed a threshold recovery. However, the threshold recovery was found to be class-independent (average recovery value of 18 dB HL per classes) and also independent of age and gender. Even if cardiovascular risk factors have been found to be involved in the pathogenesis of ISSNHL, the present study suggests that these factors do not have any significant influence on the threshold recovery in ISSNHL.
The aim of this study was to assess preferential prescribing of OC according to different thrombotic risk factors. The control group in an ongoing Danish case-control study on stroke and OCs collected in 1994 and 1995 underwent a control-only analysis concerning the occurrence of thrombotic risk factors among users of different types of OC. Specific attention was given to differences between OCs with second and third generation progestagens. The association between specific risk factors and the pill types was assessed crude and after multivariate analysis with confounder control for age and other risk factors, in order to identify risk factors, which after these corrections still had a significant confounding influence on the prescribing of OC. Users of OCs with third generation progestagens had a significantly higher proportion of familial thrombotic disposition (23.1%) than users of OCs with second generation progestagens (7.1%) (p = 0.01). After correction for age and other risk factors this difference was still highly significant (p = 0.002). Among users of third generation pills the proportion of short time users (correction for age and other risk factors (p < 0.001). Smoking, years of schooling, migraine, and body mass index did not differ significantly between the two pill groups. In Denmark, women with familial thrombotic disposition are four times more likely being prescribed OCs with third versus second generation progestagens compared with women without such a disposition. At the same time users of OCs with third generation progestagens include significantly more short time users than users of OCs with second generation progestagens. For thrombotic diseases where familial disposition or duration of use of OCs play a role for the pill-associated risk, these differences may significantly influence the thrombotic risk measures in case-control studies and non-randomized cohort studies unless confounder control is conducted for this selection.

Abnormal coagulation has been implicated in the pathogenesis of ischemic stroke, but how this association is mediated and whether it differs between ischemic stroke subtypes is unknown. We determined the shared genetic risk between 14 coagulation factors and ischemic stroke and its subtypes. Using genome-wide association study results for 14 coagulation factors from the population-based TwinsUK sample (N≈2000 for each factor), meta-analysis results from the METASTROKE consortium ischemic stroke genome-wide association study (12 389 cases, 62 004 controls), and genotype data for 9520 individuals from the WTCCC2 ischemic stroke study (3548 cases, 5972 controls-the largest METASTROKE subsample), we explored shared genetic risk for coagulation and stroke. We performed three analyses: (1) a test for excess concordance (or discordance) in single nucleotide polymorphism effect direction across coagulation and stroke, (2) an estimation of the joint effect of multiple coagulation-associated single nucleotide polymorphisms in stroke, and (3) an evaluation of common genetic risk between coagulation and stroke. One coagulation factor, factor XIII subunit B (FXIIIB), showed consistent effects in the concordance analysis, the estimation of polygenic risk, and the validation with genotype data, with associations specific to the cardioembolic stroke subtype. Effect directions for FXIIIB-associated single nucleotide polymorphisms were significantly discordant with cardioembolic disease (smallest P=5.7×10(-04)); the joint effect of FXIIIB-associated single nucleotide polymorphisms was significantly predictive of ischemic stroke (smallest P=1.8×10(-04)) and the cardioembolic subtype (smallest P=1.7×10(-04)). We found substantial negative genetic covariation between FXIIIB and ischemic stroke (rG=-0.71, P=0.01) and the cardioembolic subtype (rG=-0.80, P=0.03). Genetic markers associated with low FXIIIB levels increase risk of ischemic stroke cardioembolic subtype. © 2015 The

The development of inhibitors is the most serious iatrogenic complication affecting patients with haemophilia. This complication is associated with impaired vital or functional prognosis, reduced quality of life and increased cost of treatment. The reasons why some patients develop antibodies to factor replacement and others do not remain unclear. It is however clear that inhibitor development results from a complex multifactorial interaction between genetic and non-genetic risk factors. Environmental influences implicated in increasing the risk of inhibitor formation can be viewed as modifiable risk factors. Therefore, identification of the non-genetic risk factors may offer the possibility of personalising haemophilia therapy by modifying treatment strategies in high-risk patients in the critical early phase of factor VIII exposure. In this article, we review the non-genetic factors reported as well as the potential impact of danger signals and the different scores for inhibitor development risk stratification. © 2015 John Wiley & Sons A/S.

The population of adult survivors of childhood cancer continues to grow as survival rates improve. Although it is well established that these survivors experience various complications and comorbidities related to their malignancy and treatment, this risk is modified by many factors that are not directly linked to their cancer history. Research evaluating the influence of patient-specific demographic and genetic factors, premorbid and comorbid conditions, health behaviors, and aging has identified additional risk factors that influence cancer treatment-related toxicity and possible targets for intervention in this population. Furthermore, although current long-term follow-up guidelines comprehensively address specific therapy-related risks and provide screening recommendations, the risk profile of the population continues to evolve with ongoing modification of treatment strategies and the emergence of novel therapeutics. To address the multifactorial modifiers of cancer treatment-related health risk and evolving treatment approaches, a patient-centered and risk-adapted approach to care that often requires a multidisciplinary team approach, including medical and behavioral providers, is necessary for this population.

The aim of this study was to assess the relative influence of school class on health behaviour among adolescents versus that of the family's socioeconomic status and individual factors among adolescents. The material comprised 3,458 students in grades 8 and 9 in 244 school classes. Data were collected through questionnaires completed by the students and by their class teacher and information from the school physician. Multilevel analysis was used to indicate the relative significance of individual and school class characteristics. We find no consistent pattern between the mother's socioeconomic status and the included health behaviour measurements; however, adolescents from the lower socioeconomic groups had a higher risk of unhealthy dietary habits and adolescents whose mothers were unemployed had a significantly lower risk of drinking alcohol weekly versus all other adolescents. Not living with both biological parents, focusing on friends, and not being very academically proficient were associated with an increased risk of harmful health behaviour. Health behaviour varied substantially between school classes, especially for daily smoking, weekly alcohol consumption, and use of hashish and other euphoriants. Circumstances in the school class more profoundly influenced risk behaviour among adolescents (smoking, alcohol consumption, and use of hashish or other euphoriants) than their dietary habits (eating breakfast, frequent intake of fruit and vegetables, and frequent intake of soft drinks). The school class had the relatively strongest influence on adolescents' risk behaviour (smoking, alcohol intake, and use of hashish or other euphoriants), whereas family circumstances comprised the strongest influence on dietary habits.

Coeliac disease is triggered by an interplay of environmental and genetic factors and is one of the most prevalent autoimmune diseases in children, occurring in about 1% of Europeans. Over the last few decades, there has been a growing interest in the role of the perinatal environment in coeliac disease and this review discusses the growing body of literature on coeliac disease and perinatal risk factors. There is still only circumstantial evidence that the perinatal environment influences coeliac disease development. Large-scale cohort studies and emerging scientific concepts, such as epigenetics, may help us establish the role of these environmental factors. ©2015 Foundation Acta Paediatrica.

In China, public concern continues to mount regarding the risks of excessive Internet use among adolescents. This study investigated the factors influencing Internet addiction and adolescent risk behaviors among excessive Internet users. Proposing a conceptual model with a theoretical origin in risk behavior theory and media dependency theory, this study examined the influence of personality traits, online gaming, Internet connectedness (both the overall index and various scopes), and demographics on Internet addiction and risk behaviors (smoking, drinking, gambling, and risky sexual behaviors). Clinical data (N = 467) were retrieved from one of the earliest and largest Internet addiction clinics in China. The findings reveal that certain personality traits are significantly associated with Internet addiction and risk behaviors. Online gaming had a strong impact on both Internet addiction and risk behaviors among excessive Internet users. The study also reveals that various scopes of Internet connectedness, such as site scope, facilitate addictive Internet use, and risk behaviors among adolescents. The findings can contribute to the prevention of and intervention into Internet addiction and adolescent risk behaviors.

The influence of several risk factors for UI in pregnancy and postpartum were analyzed. Patients with persistent UI at 6 months postpartum were trained to do pelvic floor exercises. Patients with UI before pregnancy were excluded from the study. UI in the third trimester was 31%. Analyzed risk factors did not condition a higher percentage of UI. Prevalence of UI was 11.3% at 3 months postpartum and 6.9% at 6 months. 70% of the incontinent patients already had it during pregnancy and it appeared de novo post-delivery in 30% of the patients. Prevalence of UI after delivery was higher in women with UI in pregnancy and lower in caesarean cases. Most women improved with pelvic floor exercises. Analysed risk factors did not significantly increase UI in pregnancy. Prevalence of UI after delivery is higher in women with UI in pregnancy and lower in caesarean cases. Postpartum pelvic floor exercises for three months in patients with persistent stress UI at 6 months postpartum clearly improved the degree of continence.

To investigate the overall incidence and risk factors for persistent pain and its interference with daily life after cesarean section. Prospective long-term follow-up study. Karolinska University Hospital, Stockholm, Sweden. 260 healthy women who underwent elective cesarean section. Information on demographics, medical history, postoperative pain and analgesic requirements was collected. A questionnaire consisting of the Brief Pain Inventory was posted at 3, 6 and 12 months after surgery. Women rated pain intensity as well as interference with factors related to general function and quality of life. The overall incidence and risk factors for persistent postoperative pain at three time points. Persistent pain was considered a secondary outcome. At 3, 6 and 12 months respectively 40, 27 and 22% of patients reported pain in one or more locations, in the surgical site as well as in other areas. A psychological indication, as well as a first cesarean section, increased the risk for pain at 3 months. Severe postoperative pain in the immediate postoperative period or undergoing a first cesarean section were significant independent risk factors for the development of persistent pain up to 6 months after cesarean section. Parameters related to quality of life were significantly impaired in women with persistent pain. Several factors, including severe postoperative pain, were shown to influence the risk for persistent pain after cesarean section. Long-term pain markedly affected women's wellbeing. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

Full Text Available Many lifestyle patterns are established when children are young. Research has focused on the potential role of parents as a risk factor for non communicable disease in children, but there is limited investigation of the role of other caregivers, such as grandparents. The aim of this review was to identify and synthesise evidence for any influence grandparents' care practices may have on their grandchildren's long term cancer risk factors. A systematic review was carried out with searches across four databases (MEDLINE, Embase, Web of Science, PsycINFO as well as searches of reference lists and citing articles, and Google Scholar. Search terms were based on six areas of risk that family care could potentially influence-weight, diet, physical activity, tobacco, alcohol and sun exposure. All study designs were included, as were studies that provided an indication of the interaction of grandparents with their grandchildren. Studies were excluded if grandparents were primary caregivers and if children had serious health conditions. Study quality was assessed using National Institute for Health and Care Excellence checklists. Grandparent impact was categorised as beneficial, adverse, mixed or as having no impact. Due to study heterogeneity a meta-analysis was not possible. Qualitative studies underwent a thematic synthesis of their results. Results from all included studies indicated that there was a sufficient evidence base for weight, diet, physical activity and tobacco studies to draw conclusions about grandparents' influence. One study examined alcohol and no studies examined sun exposure. Evidence indicated that, overall, grandparents had an adverse impact on their grandchildren's cancer risk factors. The theoretical work in the included studies was limited. Theoretically underpinned interventions designed to reduce these risk factors must consider grandparents' role, as well as parents', and be evaluated robustly to inform the evidence base

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.)

Little is known about the environmental and organisational determinants of workplace violence in correctional health settings. This paper describes the views of health professionals working in these settings on the factors influencing workplace violence risk. All employees of a large correctional health service in New South Wales, Australia, were invited to complete an online survey. The survey included an open-ended question seeking the views of participants about the factors influencing workplace violence in correctional health settings. Responses to this question were analysed using qualitative thematic analysis. Participants identified several factors that they felt reduced the risk of violence in their workplace, including: appropriate workplace health and safety policies and procedures; professionalism among health staff; the presence of prison guards and the quality of security provided; and physical barriers within clinics. Conversely, participants perceived workplace violence risk to be increased by: low health staff-to-patient and correctional officer-to-patient ratios; high workloads; insufficient or underperforming security staff; and poor management of violence, especially horizontal violence. The views of these participants should inform efforts to prevent workplace violence among correctional health professionals.

AIMS: The aim of this study was to assess the relative influence of school class on health behaviour among adolescents versus that of the family's socioeconomic status and individual factors among adolescents. METHODS: The material comprised 3,458 students in grades 8 and 9 in 244 school classes...... the mother's socioeconomic status and the included health behaviour measurements; however, adolescents from the lower socioeconomic groups had a higher risk of unhealthy dietary habits and adolescents whose mothers were unemployed had a significantly lower risk of drinking alcohol weekly versus all other...... adolescents. Not living with both biological parents, focusing on friends, and not being very academically proficient were associated with an increased risk of harmful health behaviour. Health behaviour varied substantially between school classes, especially for daily smoking, weekly alcohol consumption...

To investigate the combined influence of diet quality and physical activity on cardiovascular disease (CVD) risk factors in adolescents, adolescents (n = 1513; 12.5-17.5 years) participating in the Healthy Lifestyle in Europe by Nutrition in Adolescence study were studied. Dietary intake was registered using a 24-h recall and a diet quality index was calculated. Physical activity was assessed by accelerometry. Lifestyle groups were computed as: healthy diet and active, unhealthy diet but active, healthy diet but inactive, and unhealthy diet and inactive. CVD risk factor measurements included cardiorespiratory fitness, adiposity indicators, blood lipid profile, blood pressure, and insulin resistance. A CVD risk score was computed. The healthy diet and active group had a healthier cardiorespiratory profile, fat mass index (FMI), triglycerides, and high-density lipoprotein cholesterol (HDL-C) levels and total cholesterol (TC)/HDL-C ratio (all P ≤ 0.05). Overall, active adolescents showed higher cardiorespiratory fitness, lower FMI, TC/HDL-C ratio, and homeostasis model assessment index and healthier blood pressure than their inactive peers with either healthy or unhealthy diet (all P ≤ 0.05). Healthy diet and active group had healthier CVD risk score compared with the inactive groups (all P ≤ 0.02). Thus, a combination of healthy diet and active lifestyle is associated with decreased CVD risk in adolescents. Moreover, an active lifestyle may reduce the adverse consequences of an unhealthy diet. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
Many countries are experiencing a period in which traditional values are being questioned; plans for technological development are being met by a variety of individual and group demands for a closer examination of the associated benefits and risks and a consideration of social values and concerns in the regulatory process. This has created conditions of conflict with some groups sponsoring proposals intended to fulfill perceived social needs while other groups, with different perceptions of society's needs, work actively in opposition. Only in recent years, as the rate of technological innovation has increased, has significant attention been given to the rapid rate of social and cultural change and the associated risks which have emerged. The degree to which an individual responds to these changes is related to his perception of their importance in his life; likewise, the repsonse to risk situations, on the individual and societal level, is based upon how the risks are perceived. The social response to the introduction of nuclear power provides an interesting case in point: here several studies have indicated that nuclear power plants might be considered ''safe''; however, nuclear power is nevertheless being opposed in many countries by those who perceive it as an unacceptable source of risk. This paper reviews research oriented toward understanding the response to technological risks through identification of the specific technical, social and psychological factors which influence their perception. Several such factors have been identified which relate to the risk object, the individual at risk, and the risk situation in which the individual encounters this object. Nuclear power was found to be characterised by more of the factors tending to increase risk perception than was any other technology. It is hypothesized that, in part due to its high ''risk visibility'' and an unconscious psychological coupling with the death imagery of nuclear weapons, nuclear energy

Peptic ulcer perforation continues to be a major surgical problem. In this study, risk factors that influence morbidity and mortality in perforated peptic ulcer disease were examined. Files of 148 patients who were included in the study due to peptic ulcer perforation between January 2006 and December 2010 were retrospectively analyzed. Data regarding age, gender, complaints, time elapsed between onset of symptoms and hospital admission, physical examination findings, co-morbid diseases, laboratory and imaging findings, length of hospital stay, morbidity and mortality were recorded. The study group included 129 (87.2%) male and 19 (12.8%) female patients. The mean age was 51.7±20 (15-88) years. Forty five patients (30.4%) had at least one co-morbid disease. In the postoperative period, 30 patients (20.3%) had complications. The most common complication was wound infection. Mortality was observed in 27 patients (18.2%). The most common cause of mortality was sepsis. Multivariate analysis revealed age over 60 years, presence of co-morbidities and Mannheim peritonitis index as independent risk factors for morbidity. Age over 60 years, time to admission and Mannheim peritonitis index were detected as independent risk factors for mortality. Early diagnosis and proper treatment are important in patients presenting with peptic ulcer perforation.
To elucidate the factors influencing perception of radiation risk in people around Chernobyl, we conducted a survey in Ukraine using self-administered questionnaire consisting of 37 questions including 5 questions about radiation contamination of their living places and foodstuffs, and 9 questions about radiation and risk. The subjects were high school or university students and their parents living in Zhytomyr, Rivne, Kirovograd and Odesa regions, and Slavutych city. In each of these 5 survey areas, we distributed 330 questionnaires to students and their parents, respectively. A total of 1,536 students (93%) responded to the questionnaire, while in parents only 861 (52%) responded. In students, a significant difference by place of residence was observed in the frequency of those regarding radiation accident or radon in dwellings being highly dangerous. (author)
Full Text Available Cysticercosis is a zoonotic disease that may have a significant impact on the public health. The aim of the current study was to assess the seroprevalence of porcine cysticercosis in Northwestern Romania and the influence of several risk factors such as age, sex and season. The study included 1,288 pigs originating from 7 different counties and was conducted between May 2014 and May 2015. All pigs were reared in the traditional backyard pig system. Of these, 226 were young and 1,062 were adult pigs, 188 were males and 1,100 females. Serum samples were collected. The apDia Cysticercosis Antigen ELISA (apDia, Belgium commercial kit was used to identify the viable cysticerci of Taenia sp. Out of the 1,288 serum samples, 83 were seropositive (seroprevalence: 6.4%. The risk factors’ analysis showed that age (3.1% juveniles vs 7.1% adults [P < 0.03] and season (9.3% fall vs 11.8% winter [P <0.00001]; 3.4% spring vs 1.2% summer [P <0.00001] had a significant influence on the seropositivity, while sex had no significant influence (3.7% males vs 6.9% females, P = 0.1. Considering the genus specificity of ELISA commercial kit, the serology should be correlated with the post mortem examination in order to confirm the disease and have a Cysticercus cellulosae specific prevalence.

It is still unclear whether the inlay thickness is an important factor influencing the fracture risk of ceramic inlays. As high tensile stresses increase the fracture risk of ceramic inlays, the objective of the present finite element method (FEM) study was to biomechanically analyze the correlation between inlay thickness (T) and the induced first principal stress. Fourteen ceramic inlay models with varying thickness (0.7-2.0 mm) were generated. All inlays were combined with a CAD model of a first mandibular molar (tooth 46), including the PDL and a mandibular segment which was created by means of the CT data of an anatomical specimen. Two materials were defined for the ceramic inlays (e.max(®) or empress(®)) and an occlusal force of 100 N was applied. The first principal stress was measured within each inlay and the peak values were considered and statistically analyzed. The stress medians ranged from 20.7 to 22.1 MPa in e.max(®) and from 27.6 to 29.2 MPa in empress(®) inlays. A relevant correlation between the first principal stress and thickness (T) could not be detected, neither for e.max(®) (Spearman: r=0.028, p=0.001), nor for empress(®) (Spearman: r=0.010, p=0.221). In contrast, a very significant difference (pinlay materials (M) was verified. Under the conditions of the present FEM study, the inlay thickness does not seem to be an important factor influencing the fracture risk of ceramic inlays. However, further studies are necessary to confirm this. Published by Elsevier Ltd.
Full Text Available Abstract Background Over recent years increased emphasis has been given to performance monitoring of NHS hospitals, including overall number of hospital readmissions, which however are often sub-optimally adjusted for case-mix. We therefore conducted a study to examine the effect of various patient and disease factors on the risk of emergency medical readmission. Methods The study setting was a District General Hospital in Greater Manchester and the study period was 4.5-years. All index emergency medical admission during the study period leading to a live discharge were included in the study (n = 20,209. A multivariable proportional hazards modelling was used, based on Hospital Episodes Statistics data, to examine the influence of various baseline factors on readmission risk. Deprivation status was measured with the Townsend deprivation index score. Hazard ratios (HR and associated 95% confidence intervals (CI of unplanned emergency medical admission by sex, age group, admission method, diagnostic group, number of coded co-morbidities, length of stay and patient's deprivation status quartile, were calculated. Results Significant independent predictors of readmission risk at 12 months were male sex (HR 1.13, CI: 1.07–1.2, age (age >75 (HR 1.57, CI 1.45–1.7, number of coded co-morbidities (HR for >4 coded co-morbidities: 1.49 CI: 1.26–1.76, admission via GP referral (HR 0.93, CI 0.88–0.99 and primary diagnosis of heart failure (HR 1.33, CI: 1.16–1.53 and chronic obstructive pulmonary disease/asthma (HR 1.34, CI: 1.21–1.48.

Drought-induced water shortage and salinization are a global threat to agricultural production. With climate change, drought risk is expected to increase as drought events are assumed to occur more frequently and to become more severe. The agricultural sector's adaptive capacity largely depends on farmers' drought risk perceptions. Understanding the formation of farmers' drought risk perceptions is a prerequisite to designing effective and efficient public drought risk management strategies. Various strands of literature point at different factors shaping individual risk perceptions. Economic theory points at objective risk variables, whereas psychology and sociology identify subjective risk variables. This study investigates and compares the contribution of objective and subjective factors in explaining farmers' drought risk perception by means of survey data analysis. Data on risk perceptions, farm characteristics, and various other personality traits were collected from farmers located in the southwest Netherlands. From comparing the explanatory power of objective and subjective risk factors in separate models and a full model of risk perception, it can be concluded that farmers' risk perceptions are shaped by both rational and emotional factors. In a full risk perception model, being located in an area with external water supply, owning fields with salinization issues, cultivating drought-/salt-sensitive crops, farm revenue, drought risk experience, and perceived control are significant explanatory variables of farmers' drought risk perceptions. © 2014 Society for Risk Analysis.

The public know little about risk factors for dementia. The aim of this study was to explore belief structures underlying how plausible risk factors for dementia appear to the general public. Two thousand members of the Australian public were surveyed by telephone on their beliefs regarding dementia risk factors. Factor analysis was performed on 17 modifiable behaviours that were rated by participants as increasing, not changing or decreasing the risk of dementia. Three factors were obtained - Health and Lifestyle, Activity, and Nutrition. Items loading on the Health and Lifestyle factor were management of cardiovascular risk factors, drinking more water, reducing stress, coffee and tea, and alcohol intake. Items loading on the Activity factor were mental, physical and social activity and getting out and about more. Items loading on the Nutrition factor were eating foods high in omega-3 fatty acids, antioxidants and estrogen, using non-aluminium cookware and taking vitamin and nutritional supplements. Factors were characterised by similarity of items, rather than level of scientific evidence of an association with dementia. Factor scale scores differed according to sociodemographic characteristics. The public do not process dementia risk factor information based on level of scientific evidence.

This study attempts to assess the association between surgeon personality factors (measured by the Myers-Briggs Type Indicator personality inventory (MBTI(®))) and risk tolerance (measured by the Revised Physicians' Reactions to Uncertainty (PRU) and Physician Risk Attitude (PRA) scales). Instrument assessing surgeon personality profile (MBTI) and 2 questionnaires measuring surgeon risk tolerance and risk aversion (PRU and PRA). Saint Raphael campus of Yale New Haven Hospital in New Haven, Connecticut. Twenty categorical surgery residents and 7 surgical core faculty members. The following findings suggest there might be a relationship between surgeon personality factors and risk tolerance. In certain areas of risk assessment, it appears that surgeons with personality factors E (Extravert), T (Thinking), and P (Perception) demonstrated higher tolerance for risk. Conversely, as MBTI(®) dichotomies are complementary, surgeons with personality factors I (Introvert), F (Feeling), and J (Judgment) suggest risk aversion on these same measures. These findings are supported by at least 2 studies outside medicine demonstrating that personality factors E, N, T, and P are associated with risk taking. This preliminary research project represents an initial step in exploring what may be considered a fundamental component in a "successful" surgical personality. © 2013 Association of Program Directors in Surgery.

Prior research has identified multiple factors that influence suicidal ideation (SI) among bullied youth. The effects of school bullying on SI cannot be considered in isolation. In this study, we examined the influence of school bullying on SI, through a constellation of risks, which include depressive and anxiety symptoms, family conflict, and alcohol, tobacco, and other drug (ATOD) use. We also provide recommendations for therapists working with bullied youth. Our sample consisted of 488 adolescents (ages 10-18 years) from a northern New Jersey, United States suburban community. Students were recruited through the district's physical education and health classes. Students responded to multiple measures, which included family cohesion/conflict, ATOD use, mental health indicators, SI, and school bullying experiences. Following preliminary analyses, several logistic regression models were used to assess the direct influence of bullying on SI, as well as the unique effects of family conflict, depressive and anxiety symptoms, and substance use. In addition, a parallel multiple mediating model with the PROCESS macro in SPSS was used to further assess mediating effects. Logistic regression results indicated that school bullying increased the odds of SI among males and females and that when mediating variables were added to the model, bullying no longer had a significant influence on SI. Overall, these results display that for both males and females, school bullying was a significant contributor to SI. Results from the parallel multiple mediating model further illustrated the mediating effects that family conflict, depression, and ATOD use had between bullying and SI. Some variation was noted based on gender. This study draws attention to the multiple experiences associated with school bullying on SI, and how these results may differ by gender. The results of this study are particularly important for those working directly and indirectly with bullied youth. Therapists

Breast cancer patients' misunderstanding of their systemic cancer recurrence risk has consequences on decision-making and quality of life. Little is known about how women derive their risk estimates. Using Los Angeles and Georgia's SEER registries (2014-2015), a random sample of early-stage breast cancer patients was sent surveys about 2 to 3 months after surgery ( N = 3930; RR, 68%). We conducted an inductive thematic analysis of open-ended responses about why women chose their risk estimates in a uniquely large sub-sample ( N = 1,754). Clinician estimates of systemic recurrence risk were provided for patient sub-groups with DCIS and with low-, intermediate-, and high-risk invasive disease. Women's perceived risk of systemic recurrence (0% to 100%) was categorized as overestimation, reasonably accurate estimation, or underestimation (0% for invasive disease) and was compared across identified factors and by clinical presentation. Women identified 9 main factors related to their clinical experience (e.g., diagnosis and testing; treatment) and non-clinical beliefs (e.g., uncertainty; spirituality). Women who mentioned at least one clinical experience factor were significantly less likely to overestimate their risk (12% v. 43%, P risk (63% v. 20%, P risk of systemic recurrence. Clinician discussions about recurrence risk should address uncertainty and relevance of family and personal history.

In two empirical surveys in Germany the link between the information respondents have about climate change and their risk perception of the phenomenon was analysed. We found that a better understanding of the effects of climate change might lead to a decrease of the perceived hazard. In contrast, a high self-declared knowledge about climate change might correspond with higher risk perception. Further factors affecting the risk perception of climate change are gender, experience of extreme wea...

Given increases in marijuana use and driving under the influence (DUI), it is critical to identify those at risk in order to inform intervention efforts. We used a socioecological framework to examine correlates of level of marijuana use and DUI in the past month among young adult marijuana users. We recruited 1567 participants aged 18-34 years via Facebook ads targeting tobacco and marijuana users in August 2014 to complete an online survey assessing marijuana use and DUI, as well as related multilevel factors. Analyses focused on 649 participants reporting past 30-day marijuana use. The sample was an average age of 24.48 (SD = 5.10), 43.9% female, and 76.4% White and used marijuana an average of 17.86 (SD = 11.29) days in the past month. Notably, 48.4% reported driving after marijuana use at least once in the past month, and 74.0% were passengers. Multivariable regression indicated that greater use was associated with: being older; being male; greater symptoms of dependence; residing in a state with recreational marijuana legalized; having a medical marijuana card; having parents and more friends who use; higher coping motives; lower perceived harm to health; and less concern about driving after marijuana use (adjusted R-squared = 0.294). Correlates of driving after using marijuana in the past month included: being younger; more frequent use; having more friends who use; higher enhancement motives; and less concern about driving after using (Nagelkerke R-squared = 0.442). Conclusions/Importance: Interventions and campaigns should address social norms and risk perceptions regarding marijuana use, particularly as it relates to DUI.

The economic, social, cultural and political milieus that influence HIV risk behaviors along the U.S.- Mexico border are understudied. In an effort to appropriately inform interventions targeting structural influences, we compared injecting drug using populations living in two cities—Ciudad Juárez, Chihuahua and Tijuana, Baja California— situated on the Mexico-U.S. border. These populations presented with similar demographic profiles, but differed significantly in terms of social and environmental influences that can influence both risk and protective factors (e.g., family drug use, migration, drug use patterns). We observed distinct behavioral and structural influences in these two border cities that will require tailored intervention strategies to reduce HIV transmission. PMID:19464228
Full Text Available The purpose of this study is to analyse the relation between risk and protective factor and substance use in adolescence, including tobacco use, drunkenness and consumption of illicit drugs. The sample included 3494 students, mean age 15 years old, in the 8th and 10th grades from the public school system, of primary and secondary schools in Portugal. Data collection was held within the HBSC (Health Behavior in School-aged Children survey from 2010. For the purpose of this specific study, the questionnaire includes questions about risk and protective behaviors and substance use, namely tobacco, drunkenness and illicit drug consumption. Results confirmed that adolescents with higher levels of protective factors seem to consume fewer substances and adolescents who present higher levels of risk factors are more likely to consume all the substances in the study. There were statistically significant differences for the majority of risk and protective behaviours regarding tobacco, drunkenness and illicit drugs. Although risk factors have a higher impact on substance use, the existence of protective factors seems to fade such impact.

Research has reported that not only characteristics of the perpetrator but also characteristics of the victim influence risk for intimate partner violence (IPV). This would suggest that prevention of repeat abuse could benefit from a focus on both perpetrator and victim characteristics. Knowledge on factors that are within victims' sphere of…

BACKGROUND AND OBJECTIVES: Prenatal risk factors for childhood overweight may operate indirectly through development in body size in early life and/or directly independent hereof. We quantified the effects of maternal and paternal body mass index (BMI), maternal age, socioeconomic position (SEP......), parity, gestational weight gain, maternal smoking during pregnancy, caesarean section, birth weight, and BMI at 5 and 12 months on BMI and overweight at 7 and 11 years. METHODS: Family triads with information on maternal, paternal and child BMI at ages 7 (n=29 374) and 11 years (n=18 044) were selected...... from the Danish National Birth Cohort. Information originated from maternal interviews and medical health examinations. Path analysis was used to estimate the direct and indirect effects of prenatal risk factors on childhood BMI z-scores (BMIz per unit score of the risk factor). Logistic regression...

This study aims to assess the psychiatric morbidity of persons at risk of homelessness and to analyze correlations and risk factors between homelessness and mental disorders. The sample included 101 citizens of Mannheim, Germany, who were immediately threatened by eviction. Mental disorders were diagnosed using a standardized test, and other factors were also assessed. Data from August 2000 to June 2002 were collected. Acute mental disorders requiring treatment were determined in 79.3% of the study sample. Addiction disorders (alcoholism) played a major role. Personality, anxiety, and affective disorders were even more frequent than in a control group of homeless people in the same region, whereas schizophrenia and other mental disorders were similarly prevalent. Regression analyses confirmed unemployment, alcoholism, and male gender as the most important risk factors for homelessness among people threatened by eviction. The results suggest that prevention strategies should be multidimensional and interdisciplinary.

People with disabilities are known to experience disparities in behavioral health risk factors including smoking and obesity. What is unknown is how disability, race/ethnicity, and socioeconomic status combine to affect prevalence of these health behaviors. We assessed the association between race/ethnicity, socioeconomic factors (income and education), and disability on two behavioral health risk factors. Data from the 2007-2010 Behavioral Risk Factor Surveillance System were used to determine prevalence of cigarette smoking and obesity by disability status, further stratified by race and ethnicity as well as income and education. Logistic regression was used to determine associations of income and education with the two behavioral health risk factors, stratified by race and ethnicity. Prevalence of disability by race and ethnicity ranged from 10.1 % of Asian adults to 31.0 % of American Indian/Alaska Native (AIAN) adults. Smoking prevalence increased with decreasing levels of income and education for most racial and ethnic groups, with over half of white (52.4 %) and AIAN adults (59.3 %) with less than a high school education reporting current smoking. Education was inversely associated with obesity among white, black, and Hispanic adults with a disability. Smoking and obesity varied by race and ethnicity and socioeconomic factors (income and education) among people with disabilities. Our findings suggest that disparities experienced by adults with disabilities may be compounded by disparities associated with race, ethnicity, and socioeconomic factors. This knowledge may help programs in formulating health promotion strategies targeting people at increased risk for smoking and obesity, inclusive of those with disabilities.

Full Text Available Credit risk consists of probability of non-return, which may be in the form of bankruptcy or a decrease in financial and credit situation of the lessee. The variables are extracted from the Central Bank. In this study the independent variables are measured with six factors that are called external factors. The external factors are size of leasing, ownership interest rate, foreign exchange, inflation, and Gross Domestic Product (GDP. The present study uses related observations from 31 leasing companies from 2008 to 2013 to find out the determinants of the credit risk. The combined evidences suggest that internal factors such as upfront prepayment, credit insurance contract, security deposits, time and period contract, collateral and guarantees, contract amount, as well as external factors such as interest rate, inflation, foreign exchange, Gross Domestic Product infrastructure, and credit risk are determinants in the policy-making process involving the industrial leasing. Furthermore, the empirical results indicate the size of leasing and ownership are not the significant determinants of credit risk. The results of this dissertation provide several implications for policy-makers in the leasing industry. Policy-makers will be better off employing different procedures for leasing activities in the leasing industry.

Full Text Available Urban authorities are continuously drawing up policies to promote cycling among commuters. However, these initiatives are counterproductive for the targeted objectives because they increase opportunities for bicycle theft. This paper explores Inner London as a case study to address place-specific risk factors for bicycle theft at the street-segment level while controlling for seasonal variation. The presence of certain public amenities (e.g., bicycle stands, railway stations, pawnshops was evaluated against locations of bicycle theft between 2013 and 2016 and risk effects were estimated using negative binomial regression models. Results showed that a greater level of risk stemmed from land-use facilities than from area-based socioeconomic status. The presence of facilities such as train stations, vacant houses, pawnbrokers and payday lenders increased bicycle theft, but no evidence was found that linked police stations with crime levels. The findings have significant implications for urban crime prevention with respect to non-residential land use.

The aim of the study was to assess the associations of individual and combined physical fitness components with single and clustering of cardio-metabolic risk factors in children. This 2-year longitudinal study included a total of 1635 European children aged 6-11 years. The test battery included cardio-respiratory fitness (20-m shuttle run test), upper-limb strength (handgrip test), lower-limb strength (standing long jump test), balance (flamingo test), flexibility (back-saver sit-and-reach) and speed (40-m sprint test). Metabolic risk was assessed through z-score standardization using four components: waist circumference, blood pressure (systolic and diastolic), blood lipids (triglycerides and high-density lipoprotein) and insulin resistance (homeostasis model assessment). Mixed model regression analyses were adjusted for sex, age, parental education, sugar and fat intake, and body mass index. Physical fitness was inversely associated with clustered metabolic risk (Pfitness, except for upper-limb strength (β=0.057; P=0.002) where the opposite association was found. Cardio-respiratory fitness (β=-0.124; Pcardio-respiratory fitness were even independent of the amount of vigorous-to-moderate activity (β=-0.059; P=0.029). Among all the metabolic risk components, blood pressure seemed not well predicted by physical fitness, while waist circumference, blood lipids and insulin resistance all seemed significantly predicted by physical fitness. Poor physical fitness in children is associated with the development of cardio-metabolic risk factors. Based on our results, this risk might be modified by improving mainly cardio-respiratory fitness and lower-limb muscular strength.

This study compares the ergonomic risk-factor assessments of workers with and without musculoskeletal pain. A questionnaire on the musculoskeletal pain experienced in various body regions during the 12 months and seven days preceding the data collection was administered to 473 workers from three industrial sectors. The Ergonomic Workplace Analysis method, developed by the Finnish Institute of Occupational Health (FIOH), was then used by the workers and an ergonomics expert to assess the workstations. The ergonomic quality of the workstations and the need for change were also assessed by the expert and the workers at the workstation, using visual analog scales (VAS). Results show that the workers in this study were exposed to significant musculoskeletal disorder (MSD) risk factors, according to the FIOH assessment and the high percentages of reported pain. The results also show that those who reported pain in the seven days prior to the assessment evaluated their workstations more negatively than subjects who reported no pain, while the expert found no difference between the two groups' exposure to MSD risk factors.

Infant developmental delays have been associated with several risk factors, such as familial environmental, individual and demographic characteristics. The goal of this study was to longitudinally investigate the effects of maternal knowledge and practices, home environment and biological factors on infant motor and cognitive outcomes. This was a prospective cohort study with a sample of 49 infants from Southern Brazil. The infants were assessed three times over 4 months using the Alberta Infant Motor Scale and the Bayley Scale of Infant Development (Mental Development Scale). Parents completed the Daily Activities Scale of Infants, the Affordances in The Home Environment for Motor Development - Infant Scale, the Knowledge of Infant Development Inventory and a demographic questionnaire. Generalized estimating equation with Bonferroni method as the follow-up test and Spearman correlation and multivariate linear backward regression were used. Cognitive and motor scores were strongly associated longitudinally and increased over time. Associations between the home affordances, parental practices and knowledge, and motor and cognitive development over time were observed. This relationship explained more variability in motor and cognitive scores compared with biological factors. Variability in motor and cognitive development is better explained by environment and parental knowledge and practice. The investigation of factors associated with infant development allows the identification of infants at risk and the implementation of educational programs and parental training to minimize the effects of developmental delay. © 2016 Japan Pediatric Society.

Osteoarthritis (OA) is a growing public health problem across the globe, affecting more than half of the over 65 population. In the past, OA was considered a wear and tear disease, leading to the loss of articular cartilage and joint disability. Nowadays, thanks to advancements in molecular biology, OA is believed to be a very complex multifactorial disease. OA is a degenerative disease characterized by "low-grade inflammation" in cartilage and synovium, resulting in the loss of joint structure and progressive deterioration of cartilage. Although the disease can be dependent on genetic and epigenetic factors, sex, ethnicity, and age (cellular senescence, apoptosis and lubricin), it is also associated with obesity and overweight, dietary factors, sedentary lifestyle and sport injuries. The aim of this review is to highlight how certain behaviors, habits and lifestyles may be involved in the onset and progression of OA and to summarize the principal risk factors involved in the development of this complicated joint disorder.

Urban middle-socioeconomic status (SES) subjects have high burden of cardiovascular risk factors in low-income countries. To determine secular trends in risk factors among this population and to correlate risks with educational status we performed epidemiological studies in India. Five cross-sectional studies were performed in middle-SES urban locations in Jaipur, India from years 1992 to 2010. Cluster sampling was performed. Subjects (men, women) aged 20-59 years evaluated were 712 (459, 253) in 1992-94, 558 (286, 272) in 1999-2001, 374 (179, 195) in 2002-03, 887 (414, 473) in 2004-05, and 530 (324, 206) in 2009-10. Data were obtained by history, anthropometry, and fasting blood glucose and lipids estimation. Response rates varied from 55 to 75%. Mean values and risk factor prevalence were determined. Secular trends were identified using quadratic and log-linear regression and chi-squared for trend. Across the studies, there was high prevalence of overweight, hypertension, and lipid abnormalities. Age- and sex-adjusted trends showed significant increases in mean body mass index (BMI), fasting glucose, total cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides (quadratic and log-linear regression, p trends showed increase in overweight and decrease in smoking (p trends in BMI and total and LDL cholesterol and accentuated trends in systolic BP, glucose, and HDL cholesterol. There was significant association of an increase in education with decline in smoking and an increase in overweight (two-line regression p trends for systolic BP, glucose and HDL cholesterol, and BMI.

The aim of this study was to identify occupational activities important for the development of arthrosis of the knee, taking into account the confounding factors that were suspected or could be recognized. In the archives of the Department of Diagnostic Radiology at the Malmoe University Hospital all radiographs of weight-bearing knees of patients with painful knee joints from the period 1982-1986 were reassessed. We found 340 probands, i.e., subjects with arthrosis of the knee of at least grade 1 in the Ahlbaeck classification. These probands and their age- and sex-matched controls (680) were analyzed by a validated questionnaire for details of activities at work inducing knee moment over three 15-year-periods as well as their history of knee injuries at work or in their leisure time. The questionnaire was answered by 266 (79%) arthrosis probands and 463 controls (70%). The results of the questionnaire answers and of the recorded history of knee injuries were statistically analyzed by logistic regression. The relative risk of knee arthrosis was slightly increased (RR: 1.9; CI: 1.4-2.7) in probands with weight-bearing knee bending, i.e., dynamic load of the knee joint when bending, whereas knee injuries (meniscectomies and haemarthrosis) were associated with a higher risk. Weight-bearing knee bending corrected for confounders was not a significant factor for knee arthrosis. Overweight was observed to increase the relative risk. A sedentary profession had, on the other hand, a low risk. The knee injuries (66) were, but for 9 probands, sustained in leisure activities, mainly soccer. We thus conclude that work which induces weight-bearing knee bending by itself does not significantly increase the risk of developing arthrosis of the knee - knee injuries and overweight are more important

Full Text Available In the absence of intervention, the rate of vertical transmission of HIV can range from 15-45%. With the inclusion of antiretroviral drugs during pregnancy and the choice of delivery route this amounts to less than 2%. However ARV use during pregnancy has generated several questions regarding the adverse effects of the gestational and neonatal outcome. This study aims to analyze the risk factors for vertical transmission of HIV-1 seropositive pregnant women living in Rio Grande and the influence of the use of ARVs in pregnancy outcome. Among the 262 pregnant women studied the rate of vertical transmission of HIV was found to be 3.8%. Regarding the VT, there was a lower risk of transmission when antiretroviral drugs were used and prenatal care was conducted at the referral service. However, the use of ART did not influence the outcome of pregnancy. However, initiation of prenatal care after the first trimester had an influence on low birth weight, as well as performance of less than six visits increased the risk of prematurity. Therefore, the risk factors analyzed in this study appear to be related to the realization of inadequate pre-natal and maternal behavior.

Obesity is a main risk factor in metabolic syndrome. Gender is known to influence the risk of obesity and other cardiovascular risk factors. However, it remains to be determined whether there is a gender-specific difference in the relationship between obesity and accumulation of other cardiometabolic risk factors such as hypertension, dyslipidemia, and diabetes. The aim of this study was to determine whether the association between obesity and a cluster of other cardiometabolic risk factors is modified by gender. The subjects were 17,791 Japanese men and women who were divided into younger (35-40 years) and older (60-70 years) age groups. The relationships between obesity (body mass index [BMI] ≥25 kg/m(2) or waist-to-height ratio [WHtR] ≥0.5) and multiple cardiometabolic risk factors (≥2 of the risk factors of high blood pressure, dyslipidema, and hyperglycemia) were compared between men and women in each age group. In the younger group, the crude odds ratios (ORs) for multiple cardiometabolic risk factors in obese versus nonobese subjects were significantly higher in women than in men (BMI: 6.23 [range, 5.53-7.02] in men vs 16.63 [range, 12.37-22.37] in women, P difference was not found in the older group (BMI: 3.03 [range, 2.69-3.42] in men vs 2.92 [range, 2.33-3.67] in women P = 0.076; WHtR: 3.11 [range, 2.78-3.47] in men vs 2.50 [range, 2.02-3.09] in women, P gender and each adiposity index for multiple cardiometabolic risk factors were significantly higher than a reference level of 1.00 in the younger group (BMI: 2.68 [range, 1.95-3.69], P obesity and a cluster of cardiometabolic risk factors is stronger in women than in men, and this gender-specific difference exists in younger (35-40 years) but not in older (60-70 years) individuals.

Many countries are experiencing a period in which traditional values are being questioned. The social response to plans for further technological development has often taken the form of demands for a closer examination of the associated benefits and risks, and consideration of social values in public planning and decision processes. A theoretical framework for interdisciplinary risk assessment studies is presented to allow the balancing of complex technical data with measures of the corresponding social values. The cognitive limitations which affect rationality in intuitive decision-making are summarized as background for the introduction of formal decision methodologies. Methods for obtaining value measures are reviewed and an attitude-based method is developed in detail; this model allows identification of the relative importance of the technical, psychological and social factors which underlie attitudes and indicates which factors differentiate between social groups. A pilot application to nuclear power indicated that, for the subjects tested, attitudes pro and con were primarily determined by strongly differing beliefs about the benefits of nuclear power. Symbolic aspects of the nuclear controversy are reviewed, including psychological associations with nuclear weapons. It is suggested that nuclear energy is providing a forum to evaluate a wide range of social issues, perhaps playing a symbolic role in a dialogue about the shape and direction of a technologically-determined future.

OBJECTIVE: To investigate age-related shifts in the relative importance of SBP and DBP as predictors of cardiovascular mortality and all-cause mortality and whether these relations are influenced by other cardiovascular risk factors. METHODS: Using 42 cohorts from the MORGAM Project with baseline...... 82 mmHg [1.03 (1.02-1.05)]. BP values below the cut-points were inversely related to mortality risk. Taking into account the age × BP interaction, there was a gradual shift from DBP (19-26 years) to both DBP and SBP (27-62 years) and to SBP (63-78 years) as risk factors for stroke mortality and all......-cause mortality, but not CHD mortality. The age at which the importance of SBP exceeded DBP was for stroke mortality influenced by sex, cholesterol, and country risk. CONCLUSION: Age-related shifts to the superiority of SBP exist for stroke mortality and all-cause mortality, and for stroke mortality...

The role of prior cardiovascular risk (CVR) in the multifactorial process of returning to work after a cerebrovascular event has not been adequately investigated. Therefore, the objective of the present study was to analyse the association between previous CVR level, cardiovascular risk factors (CVRFs) and return-to-work (RTW) following cerebrovascular disease. This was a prospective observational study. We analysed a cohort of 348 patients who had experienced an episode of cerebrovascular disease-related work absence. These individuals were selected from the ICARIA study (Ibermutuamur CArdiovascular RIsk Assessment). Global CVR was assessed using the SCORE system. We investigated the association between demographics, work-related variables, CVRFs and RTW following a cerebrovascular event. We found that a total of 254 individuals (73.0%; 95% CI: 68.3-77.7) returned to work after cerebrovascular disease. Also, we observed a median loss of 12 working years due to disability. Moreover, adjusting for potential confounders revealed that low CVR level and the absence of the following CVRFs was associated with a higher likelihood of RTW: low vs moderate-to-high CVR level (OR: 2.55; 95% CI: 1.42-4.57), no hypertension before stroke (OR: 1.95; 95% CI: 1.11-3.41), non-smoker status (OR: 2.26; 95% CI: 1.30-3.93) and no previous diabetes (OR: 2.46; 95% CI: 1.26-4.79). Low CVR, along with the absence of several CVRFs, can be used to predict RTW rates following cerebrovascular events. Therefore, controlling hypertension, tobacco consumption and diabetes might contribute to the effectiveness of multidisciplinary rehabilitation and/or secondary/tertiary prevention programs for cerebrovascular disease. © The European Society of Cardiology 2014.

OBJECTIVE Early pubertal onset in females is associated with increased risk for adult obesity and cardiovascular disease, but whether this relationship is independent of preceding childhood growth events is unclear. Furthermore, the association between male puberty and adult disease remains unknown. To clarify the link between puberty and adult health, we evaluated the relationship between pubertal timing and risk factors for type 2 diabetes and cardiovascular disease in both males and females from a large, prospective, and randomly ascertained birth cohort from Northern Finland. RESEARCH DESIGN AND METHODS Pubertal timing was estimated based on pubertal height growth in 5,058 subjects (2,417 males and 2,641 females), and the relationship between puberty and body weight, glucose and lipid homeostasis, and blood pressure at age 31 years was evaluated with linear regression modeling. RESULTS Earlier pubertal timing associated with higher adult BMI, fasting insulin, diastolic blood pressure, and decreased HDL cholesterol in both sexes (P < 0.002) and with higher total serum cholesterol, LDL cholesterol, and triglycerides in males. The association with BMI and diastolic blood pressure remained statistically significant in both sexes, as did the association with insulin levels and HDL cholesterol concentrations in males after adjusting for covariates reflecting both fetal and childhood growth including childhood BMI. CONCLUSIONS We demonstrate independent association between earlier pubertal timing and adult metabolic syndrome-related derangements both in males and females. The connection emphasizes that the mechanisms advancing puberty may also contribute to adult metabolic disorders. PMID:22338106

To assess the prognostic influence of pre-morbid type 2 diabetes mellitus, arterial hypertension and cardiovascular (CV) risk profile on ALS phenotype and outcome in a population-based cohort of Italian patients. A total of 650 ALS patients from the Piemonte/Valle d'Aosta Register for ALS, incident in the 2007-2011 period, were recruited. Information about premorbid presence of type 2 diabetes mellitus, arterial hypertension was collected at the time of diagnosis. Patients' CV risk profile was calculated according to the Joint British Societies' guidelines on prevention of cardiovascular disease in clinical practice (JBS2). At the univariate analysis, the presence of pre-morbid arterial hypertension was associated with a higher age at onset of ALS and a shorter survival, and patients with a high CV risk profile had a worse prognosis than those with a low CV risk profile. The Cox multivariable analysis did not confirm such findings. Type 2 diabetes mellitus did not modify either the phenotype or the prognosis of ALS patients. This study performed on a large population-based cohort of ALS patients has demonstrated that arterial hypertension, type 2 diabetes and CV risk factors, calculated using the Framingham equation, do not influence ALS phenotype and prognosis.

The influence of rheumatoid arthritis (RA) on the lumbar spine has received relatively little attention compared with cervical spine, and few studies have been conducted for adjacent segment disease (ASD) after lumbar fusion in patients with RA. The present study aims to determine the incidence of ASD requiring surgery (ASDrS) after short lumbar fusion and to evaluate risk factors for ASDrS, including RA. This is a retrospective cohort study. The present study included 479 patients who underwent lumbar spinal fusion of three or fewer levels, with the mean follow-up period of 51.2 (12-132) months. The development of ASD and consequent revision surgery were reviewed using follow-up data. The ASDrS-free survival rate of adjacent segments was calculated through Kaplan-Meier method. The log-rank test and Cox regression analysis were used to evaluate risk factors comprising RA, age, gender, obesity, osteoporosis, diabetes, smoking, surgical method, and the number of fusion segments. After short lumbar fusion, revision surgery for ASD was performed in 37 patients (7.7%). Kaplan-Meier analysis predicted that the ASDrS-free survival rate of adjacent segments was 97.8% at 3 years, 92.7% at 5 years, and 86.8% at 7 years. In risk factor analysis, patients with RA showed a 4.5 times higher risk of ASDrS than patients without RA (pfusion showed a 2.7 times higher risk than patients with one- or two-segment fusion (p=.005). Adjacent segment disease requiring surgery was predicted in 13.2% of patients at 7 years after short lumbar fusion. Rheumatoid arthritis and the number of fusion segments were confirmed as risk factors. Copyright © 2018 Elsevier Inc. All rights reserved.
Full Text Available To determine the influence of cardiorespiratory fitness (hereafter “fitness” and physical activity levels on cardiometabolic risk factors in premenopausal women going through the menopause transition. An ancillary study including 66 premenopausal women who participated to a 5-year observational, longitudinal study (2004 to 2009 in Ottawa on the effects of menopause transition on body composition and cardiometabolic risk factors. Women underwent a graded exercise test on treadmill to measure peak oxygen uptake (VO2 peak at year 1 and 5 and physical activity levels were measured using accelerometers. Cardiometabolic risk factors included: waist circumference, fasting plasma lipids, glucose and insulin levels, HOMA-IR score, c-reactive protein, apolipoprotein B (apoB and resting systolic and diastolic blood pressure. Change in fitness was not associated with changes in cardiometabolic risk factors. The changes in total physical activity levels on the other hand showed a significant negative association with apoB levels. Three-way linear mixed model repeated measures, showed lower values of waist circumference, fasting triglycerides, insulin levels, HOMA-IR score, apoB and diastolic blood pressure in women with a fitness ≥30.0 mlO2 kg−1 min−1 compared to women with a fitness <30.0 mlO2 kg−1 min−1 (P < 0.05. However, only fasting triglycerides was lower in women with physical activity levels ≥770.0 Kcal/day (P < 0.05. Between fitness and physical activity levels, fitness was associated with more favorable values of cardiometabolic risk factors in women followed for 5 years during the menopause transition.

Previous research into age-related variables relevant to girls and young women being involved in commercial sexual exploitation (including prostitution) has not distinguished between its onset and limitation to adolescence and its early onset and persistence into adult life. The aims of this study were to examine variables associated with adolescent versus adult onset of commercial sexual exploitation and identify potential risk and resiliency factors differentiating adolescence-limited sexual exploitation and early-onset-adult persistent exploitation. Interviews with 174 vulnerable mostly African-American women, 23% of whom reported commercial sexual exploitation in adolescence and/or adulthood, yielded data, which were analysed using multinomial logistic regressions. Adolescent sexual victimisation, younger age at first alcohol/drug use, being a victim of intimate partner violence and sense of stigmatisation of sexual self/others were all variables associated with adolescent onset of commercial sexual exploitation. Educational attainment differentiated adolescence limited from adolescent-adult persistent exploitation; exploitation had ceased by adulthood among over two-thirds of those who completed at least high school education, but only 13% of those exploited into adult life had finished high school. As level of education was linked to cessation of exploitation by adulthood, support for vulnerable girls to complete education at least to high school level may be protective.The link between early onset of substance misuse and persistent exploitation suggests that education and support specifically targeted within this field could reduce likelihood of persistent abuse.Work directed at improvement of self-image may also reduce risk of persistent exploitation.

The aim of this study was to investigate the influence of certain psychosocial factors - insight, psycho-education, family and social support, loneliness and social isolation - on the appearance of depression and suicidal risk in schizophrenia. This was a cross-sectional study that comprised hospitalized patients with schizophrenia in the initial remission phase. The assessment of depression and suicidal risk was made by applying a semi-structured psychiatric interview that included scrutinized factors (insight, psycho-education, family and social support, loneliness and social isolation), Positive and Negative Syndrome Scale (PANSS), and Calgary Depression Scale for Schizophrenia (CDSS). On the basis of the assessment results, the sample was divided into two groups: Group of patients with depression and suicidal risk in schizophrenia (N = 53) and Control group (N = 159) of patients with schizophrenia without depression and suicidal risk. In the Group of patients with depression and suicidal risk, compared with the Control group, there was significantly higher frequency of insight in the mental status (χ² = 31.736, p psycho-education (χ² = 10.039, p = 0.002), deficit of family support (χ² = 13.359, p = 0.001), deficit of social support (χ² = 6.103, p=0.047), loneliness (χ² = 6.239, p = 0.012), and social isolation (χ² = 47.218, p psycho-education and social isolation (p psycho-social factors - insight in the mental status, lack of psycho-education, as well as social isolation - could be predictors for appearance of depression and suicidal risk in schizophrenia.

Benign paroxysmal positional vertigo (BPPV) is the most frequent type of vertigo. The treatment of canalithiasis of the posterior semicircular canal consists in performing a particle-repositioning maneuver, such as the Epley maneuver (EM). However, the EM is not effective in all cases. The objective of this study is to identify risk factors, which predict the EM failure, among the clinical variables recorded in anamnesis and patient examination. This is an observational prospective multicentric study. All patients presenting with BPPV were recruited and applied the EM and appointed for a follow-up visit 7 days later. The following variables were recorded: sex, age, arterial hypertension, diabetes, hyperlipidemia, smoking habit, alcohol consumption, migraine, osteoporosis, diseases of the inner ear, previous ipsilateral BPPV, previous traumatic brain injury, previous sudden head deceleration, time of evolution, sulpiride or betahistine treatment, experienced symptoms, outcome of the Halmagyi maneuver, laterality, cephalic hyperextension of the neck, intensity of nystagmus, intensity of vertigo, duration of nystagmus, occurrence of orthotropic nystagmus, symptoms immediately after the EM, postural restrictions, and symptoms 7 days after the EM. Significant differences in the rate of loss of nystagmus were found for six variables: hyperlipidemia, previous ipsilateral BPPV, intensity of nystagmus, duration of nystagmus, post-maneuver sweating, and subjective status. The most useful significant variables in the clinical practice to predict the success of the EM are previous BPPV and intensity of nystagmus. In the other significant variables, no physiopathological hypothesis can be formulated or differences between groups are too small.

Chronic rhinosinusitis (CRS) is an inflammation of the nose and paranasal sinuses lasting for ≥12 weeks. Endoscopic sinus surgery (ESS) is considered during difficult to treat CRS. The minimally invasive technique focuses on the transition areas rather than on the ostia. The aim of this study was to evaluate symptoms, the number of acute sinusitis episodes, and satisfaction after ESS with either preservation or enlargement of the maxillary sinus ostium. Thirty patients with moderate nonpolypous CRS were enrolled. Uncinectomy only and additional middle meatal antrostomy were randomized for each side of each patient and performed single blindly. The symptoms questionnaires were filled at four time intervals. Significant symptom reduction was achieved independently of operation technique. The number of acute sinusitis episodes indicating the exacerbation rate decreased significantly at 9 and, on average, 68 months postoperatively. However, the exacerbation rate began to increase after 9 months postoperatively. Three revisions were performed on the side with uncinectomy only and one on the side with additional antrostomy. Most patients reported good satisfaction with both procedures. There was a trend for patients with asthma and/or job exposure to report insignificantly more frequently no satisfaction with surgery, especially with the uncinectomy-only procedure. Both procedures seem to be efficient in providing symptom relief and satisfaction. More studies are needed to evaluate if patients with risk factors benefit more from an ostium-enlarging procedure.
Full Text Available Introduction: Due to existence of the risk and uncertainty in agriculture, risk management is crucial for management in agriculture. Therefore the present study was designed to determine the risk aversion coefficient for Esfarayens farmers. Materials and Methods: The following approaches have been utilized to assess risk attitudes: (1 direct elicitation of utility functions, (2 experimental procedures in which individuals are presented with hypothetical questionnaires regarding risky alternatives with or without real payments and (3: Inference from observation of economic behavior. In this paper, we focused on approach (3: inference from observation of economic behavior, based on this assumption of existence of the relationship between the actual behavior of a decision maker and the behavior predicted from empirically specified models. A new non-parametric method and the QP method were used to calculate the coefficient of risk aversion. We maximized the decision maker expected utility with the E-V formulation (Freund, 1956. Ideally, in constructing a QP model, the variance-covariance matrix should be formed for each individual farmer. For this purpose, a sample of 100 farmers was selected using random sampling and their data about 14 products of years 2008- 2012 were assembled. The lowlands of Esfarayen were used since within this area, production possibilities are rather homogeneous. Results and Discussion: The results of this study showed that there was low correlation between some of the activities, which implies opportunities for income stabilization through diversification. With respect to transitory income, Ra, vary from 0.000006 to 0.000361 and the absolute coefficient of risk aversion in our sample were 0.00005. The estimated Ra values vary considerably from farm to farm. The results showed that the estimated Ra for the subsample existing of 'non-wealthy' farmers was 0.00010. The subsample with farmers in the 'wealthy' group had an

Coastal flood protection measures have been widely implemented to improve flood resilience. However, protection levels vary among coastal megacities globally. This study compares the distinct flood protection standards for two coastal megacities, New York City and Shanghai, and investigates potential influences such as risk factors and past flood events. Extreme value analysis reveals that, compared to NYC, Shanghai faces a significantly higher flood hazard. Flood inundation analysis indicates that Shanghai has a higher exposure to extreme flooding. Meanwhile, Shanghai's urban development, population, and economy have increased much faster than NYC's over the last three decades. These risk factors provide part of the explanation for the implementation of a relatively high level of protection (e.g. reinforced concrete sea-wall designed for a 200-year flood return level) in Shanghai and low protection (e.g. vertical brick and stone walls and sand dunes) in NYC. However, individual extreme flood events (typhoons in 1962, 1974, and 1981) seem to have had a greater impact on flood protection decision-making in Shanghai, while NYC responded significantly less to past events (with the exception of Hurricane Sandy). Climate change, sea level rise, and ongoing coastal development are rapidly changing the hazard and risk calculus for both cities and both would benefit from a more systematic and dynamic approach to coastal protection.

Full Text Available Background & Objectives : Worker exposure conditions such as noise level, exposure duration, use of hearing protection devices and health behaviors are commonly related to noise induced hearing loss. The objective of this study was risk assessment of influence factors on occupational hearing loss in noise exposed workers in typical noisy process . Methods : Information about occupational exposure of seventy workers employed in a noisy press workshop was gathered using the standard questionnaire. Audiometery test was performed using the screening audiometer (Model-Mevox. Afterward, the collected data was analyzed by using the Cox model in SPSS software. Results : Based on results of the developed model, the job type and using status of HPD were most important features to induce hearing loss among workers. The risk of hearing loss among workers with the intermittent use of hearing protection was 3.1 times more than workers used their devices continuously. Relative risk of hearing loss among smoker workers compared with non-smoker was 1.1. Conclusion : The developed model could determine the effects of workers’ exposure conditions on risk of occupational hearing loss. This systematic approach can be considered as a helpful tool for determination the effectiveness of hearing conservation program and provide useful information for the managers and professionals in order to revise the existing health programs.

Monetary cutbacks have occurred in the healthcare industry with increasing incidence since the mid-1980s. Attempts at self-preservation through cost-constraint have been instituted by hospitals, Medicare and Medicaid, and private insurance companies. Curtailment of expenditures, as well as reestablishing profit, has taken many forms. These include managed care, mergers, changing profit status, and aggressive competition. The purpose of this study was to evaluate whether directors of nurse anesthesia programs (NAPs) perceived these items as being detrimental to their NAPs. Data were gathered by descriptive survey design by completing a survey tool. Findings identified directors perceived NAPs at moderate to high risk for closure because of the financial constraints hospitals are experiencing as a result of healthcare reimbursement cutbacks. We found it interesting that many directors were either unaware or considered the hospitals' financial burdens as not impacting their NAP. However, directors who had taken courses or seminars with a focus on issues affecting the financing and reimbursement of healthcare institutions perceived significantly greater risk than those who did not. Potential learning opportunities and strategies to ameliorate risk were identified. Additional education may provide the knowledge and insight to find alternatives to risk, develop strategies, and promote more successful and stable nurse anesthesia educational programs.

Most new HIV infections in Kenya occur among young people. The purpose of this study was to understand ecological factors that influence HIV-related sexual risk and resilience among young people in rural Kenya and to elicit their ideas for HIV prevention interventions. Nine focus groups (N = 199) were conducted with both female (55%) and male (45%) participants (ages 14-24 years) living in rural communities in Kenya. Findings were organized into thematic areas related to the following systems of influence: (i) intrapersonal (substance use, HIV knowledge), (ii) interpersonal (peer pressure, lack of parent-child communication, interpersonal sexual violence), (iii) institutional/community (pornography, transactional sex, 'idleness', lack of role models) and (iv) socio-cultural/policy (Kikuyu culture, Western influence, religious beliefs, HIV-related stigma and gendered sexual scripts). Results regarding the types of HIV prevention programs that participants believed should be developed for young people in rural Kenya revealed seven primary themes, including (i) HIV prevention community/group workshops, (ii) condom distribution, (iii) job skills trainings, (iv) athletic and social clubs, (v) HIV-related stigma reduction campaigns, (vi) community-wide demonstrations and (vii) other HIV/AIDS activities led by young people. Implications for the development of culturally and developmentally appropriate HIV prevention interventions for young people in rural Kenya are discussed.

Global macroeconomic imbalance combined with deregulation of US banks and increasing US real estate prices formed the basis for aggressive growth in worldwide trading of so called Collateralized Debt Obligations (CDO), i.e. similar loans pooled to create a financial derivative that can be bought or sold. The CDOs consisted mainly of prime and subprime housing loans, where the latter type is characterized by a high probability for default. Due to the growing market demand for this derivative and the subsequent shortage of prime loans, the subprime share in the CDOs increased from 43% to 71% from 2003 to 2007. Surprisingly the credit rating agencies did not change the top level (AAA) credit rating of the CDOs in the same period of time. How was this possible? And how could the tremendously resourceful firms that insured the derivatives by selling so called Credit Default Swaps to CDO owners avoid understanding the enormous risk they took on? What later was to be called the financial crisis emerges in the spring of 2008 in line with the fall in US real estate prices and subsequent evaporation of the CDO market. The chain of events that led to numerous bankruptcies and threw the world into a recession not seen since the early 1930s has been labeled a system crisis, liquidity crisis, and a crisis of confidence (in the financial markets) among others. In this paper we survey how, and to what extent, operational risk exposure in the organizations of mortgage brokers and banks, insurance companies, credit rating agencies, and investment banks contributed to the financial crisis. Bayesian Network analysis of causes and influencing factors in these four types of organizations indicates that operational risk exposure played a crucial role in triggering the financial crisis. Our findings suggest that the financial crisis for a large part was the result of an industry wide failure to manage risk in general, and operational risk in particular.
Full Text Available Abstract Background The purpose of this study was to examine the association between muscular fitness (MF, assessed by 2 components of Fitnessgram test battery, the Curl-Up and Push-Ups tests and the metabolic risk score among adolescent girls. Methods A total of 229 girls (aged 12-15 years old comprised the sample of this study. Anthropometric data (height, body mass, waist circumference were collected. Body mass index (BMI was also calculated. Muscular strength was assessed taking into account the tests that comprised the FITNESSGRAM test battery, i.e. the curl-up and the push-up. Participants were then categorized in one of 3 categories according the number of tests in which they accomplished the scores that allow them to be classified in health or above health zone. The blood pressure [BP], fasting total cholesterol [TC], low density lipoprotein-cholesterol [LDL-C], high density lipoprotein-cholesterol [HDL-C], triglycerides [TG], glucose, and a metabolic risk score (MRS were also examined. Physical Activity Index (PAI was obtained by questionnaire. Results Higher compliance with health-zone criteria (good in the 2 tests, adjusted for age and maturation, were positive and significantly (p ≤ 0.05 associated with height (r = 0.19 and PAI (r = 0.21, while a significant but negative association was found for BMI (r = -0.12; WC (r = -0.19; TC (r = -0.16; TG (r = -0.16; LDL (r = -0.16 and MRS (r = -0.16. Logistic regression showed that who were assigned to MF fittest group were less likely (OR = 0.27; p = 0.003 to be classified overweight/obese and less likely (OR = 0.26; p = 0.03 to be classified as having MRS. This last association was also found for those whom only performed 1 test under the health zone (OR = 0.23; p = 0.02. Conclusions Our data showed that low strength test performance was associated with increased risk for obesity and metabolic risk in adolescent girls even after adjustment for age and maturation.

Physical activity favorably influences atherosclerosis risk factors but only a few studies in adults considered the time watching television (TV) as a measure of physical inactivity. We therefore determined in a population-based sample of 1778 subjects from the NHLBI Family Heart Study (FHS) whether leisure time physical activity and TV watching have independent or interactive associations with cardiovascular disease risk factors and carotid artery intima-media wall thickness (IMT). Subjects were free from diabetes mellitus and clinically-ascertained coronary artery disease and did not take lipid-lowering or antihypertensive drugs. Only 0.7 and 1.3% of the variance in leisure time physical activity in women and men, respectively, was explained by the amount of TV watching. Leisure time physical activity had a clearly favorable, and TV watching an unfavorable association with anthropometric measurements (BMI (body mass index), waist girth, waist-hip ratio, subscapular and triceps skinfold thickness). The odds ratio (95% CI) of being overweight was 0.41 (0.28-0.62) in women and 0.69 (0.46-1.04) in men in the highest quartile of leisure time physical activity compared to the lowest quartile. The odds ratio increased for increasing quartiles of TV watching to 2.12 (1.45-3.10) in women and 1.61 (1.07-2.43) in men. Watching TV only 1 h per day in women with a BMI of 30 kg/m2 and doing about 75 min of moderate exercise per week was associated with a BMI 1.8 kg/m2 lower than in women watching TV 3 h per day and doing the same amount of exercise. Those with twice the amount of moderate exercise and watching TV 1 h per day had a BMI 0.45 kg/m2 lower. Furthermore, leisure time physical activity was negatively associated with concentrations of triglycerides and positively with HDL cholesterol in both genders. TV watching was significantly positively associated with triglycerides and slightly negatively with HDL cholesterol in men. The observed associations of leisure time
Full Text Available Abstract Background Longitudinal epidemiological studies involving child/adolescent mental health problems are scarce in developing countries, particularly in regions characterized by adverse living conditions. We examined the influence of psychosocial factors on the trajectory of child/adolescent mental health problems (CAMHP over time. Methods A population-based sample of 6- to 13-year-olds with CAMHP was followed-up from 2002–2003 (Time 1/T1 to 2007–2008 (Time 2/T2, with 86 out of 124 eligible children/adolescents at T1 being reassessed at T2 (sample loss: 30.6%. Outcome: CAMHP at T2 according to the Child Behavior Checklist/CBCL’s total problem scale. Psychosocial factors: T1 variables (child/adolescent’s age, family socioeconomic status; trajectory of variables from T1 to T2 (child/adolescent exposure to severe physical punishment, mother exposure to severe physical marital violence, maternal anxiety/depression; and T2 variables (maternal education, child/adolescent’s social support and pro-social activities. Results Multivariate analysis identified two risk factors for child/adolescent MHP at T2: aggravation of child/adolescent physical punishment and aggravation of maternal anxiety/depression. Conclusions The current study shows the importance of considering child/adolescent physical punishment and maternal anxiety/depression in intervention models and mental health care policies.

Tumor necrosis factor alpha (TNFA) is an important molecule in inflammatory, infectious, and tumoral processes. Inflammation is one of the early phases in the development of gastric cancer (GC). Therefore, several studies have examined the association of polymorphism in TNFA with gastritis and GC risk. A functional polymorphism, -308G>A (rs1800629), which is located in the promoter of TNFA gene, has been suggested to alter the production of TNF-α and influence cancer risk. To date, a number of studies have been carried out to investigate the relationship between the polymorphism and gastritis or GC susceptibility, but the results were conflicting. To investigate this inconsistency, we performed a meta-analysis of 36 studies for TNFA -308G>A polymorphism to evaluate the effect of TNFA on genetic susceptibility for gastritis and GC. An overall random-effects per-allele odds ratio of 1.16 (95 % confidence interval 1.04-1.29, P = 0.008) was found for the polymorphism. Significant results were also observed using dominant or recessive genetic models. In the subgroup analyses by ethnicity, significant results were found in Caucasians, whereas no significant associations were found among East Asians and other ethnic populations. No associations between the polymorphism and gastritis were observed. In addition, our data indicate that TNFA is involved in GC susceptibility and confers its effect primarily in diffuse type of tumors. Besides, -308G>A polymorphism was found to be significantly associated with both cardiac and noncardiac tumors. This meta-analysis demonstrated that the TNFA -308G>A polymorphism is a risk factor for developing GC, but the associations vary in different ethnic populations.

Accumulating data from animal and human studies indicate that the prenatal environment plays a significant role in shaping children's neurocognitive development. Clinical, epidemiologic, and basic science research suggests that two experiences relatively common in pregnancy - an unhealthy maternal diet and psychosocial distress - significantly affect children's future neurodevelopment. These prenatal experiences exert their influence in the context of one another and yet, almost uniformly, are studied independently. In this review, we suggest that studying neurocognitive development in children in relation to both prenatal exposures is ecologically most relevant, and methodologically most sound. To support this approach, we selectively review two research topics that demonstrate the need for dual exposure studies, including exemplar findings on (a) the associations between pregnant women's inadequate maternal intake of key nutrients - protein, fat, iron, zinc, and choline - as well as distress in relation to overlapping effects on children's neurocognitive development; and (b) cross-talk between the biology of stress and nutrition that can amplify each experience for the mother and fetus,. We also consider obstacles to this kind of study design, such as questions of statistical methods for 'disentangling' the exposure effects, and aim to provide some answers. Studies that specifically include both exposures in their design can begin to determine the relative and/or synergistic impact of these prenatal experiences on developmental trajectories - and thereby contribute most fully to the understanding of the early origins of health and disease. © 2012 The Author.

Surgical treatment of the medication-related osteonecrosis of the jaw (MRONJ) is still challenging. We examined the outcome of the resection of osteonecrotic lesions and the influence of potential risk factors on the operative success. Seventy six surgical interventions on 40 patients were evaluated in a prospective design with a mean follow-up of 55 weeks. Primary endpoints were: (i) maintenance of the mucosal closure and (ii) decrease of MRONJ stage. Influential variables included preoperative duration, location and diameter of MRONJ, duration and change of antiresorptive therapy, presence of actinomyces species. Only in 27.6% of cases long-term maintenance of the mucosal closure was achieved. However, stage II patients decreased to stage I in 81% after surgery (p < 0.01) and stage III patients improved in 83% of cases (OR = 8.08; p = 0.07). Stage I patients profited only in 38% by surgical intervention. MRONJ recurrence after surgery was associated with extended preoperative MRONJ duration (p = 0.015). There was no significance of further influential variables, but MRONJ of the upper jaw seems prognostically more favorable. Advanced stages of MRONJ benefit from surgical treatment, whereas stage I diseases may also be treated conservatively. An early intervention reduces the risk of recurrence.

We evaluated the genetic and environmental contributions to metabolic cardiovascular risk factors and their mutual associations. Eight metabolic factors (body mass index, waist circumference, waist-to-hip ratio, systolic blood pressure, diastolic blood pressure, total serum cholesterol, serum triglycerides, and serum uric acid) were measured in 508 twin pairs aged 8-17 years from the Qingdao Twin Registry, China. Linear structural equation models were used to estimate the heritability of these traits, as well as the genetic and environmental correlations between them. Among boys, body mass index and uric acid showed consistently high heritability (0.49-0.81), whereas other traits showed moderate to high common environmental variance (0.37-0.73) in children (8-12 years) and adolescents (13-17 years) except total cholesterol. For girls, moderate to high heritability (0.39-0.75) were obtained for six metabolic traits in children, while only two traits showed high heritability and others mostly medium to large common environmental variance in adolescents. Genetic correlations between the traits were strong in both boys and girls in children (r g = 0.64-0.99 between body mass index and diastolic blood pressure; r g = 0.71-1.00 between body mass index and waist circumference), but decreased for adolescent girls (r g = 0.51 between body mass index and waist-to-hip ratio; r g = 0.55 between body mass index and uric acid; r g = 0.61 between body mass index and systolic blood pressure). The effect of genetic factors on most metabolic traits decreased from childhood to adolescence. Both common genetic and specific environmental factors influence the mutual associations among most of the metabolic traits.

The current investigation addressed the potential for unique influences of perceived childhood maltreatment, adverse family-life events, and parent-child relational trauma on the lifetime occurrence and addictive features of non-suicidal self-injury (NSSI). Participants included 957 undergraduate students (747 females; M = 20.14 years, SD = 3.88) who completed online questionnaires regarding the key variables under study. Although self-injuring youth reported more experiences with each family-based risk factor, different patterns of association were found when lifetime engagement in NSSI or its addictive features were under study. Perceived parent-child relational trauma was uniquely linked with NSSI behavior after accounting for perceived childhood maltreatment; adverse family-life events had an additional unique association. In contrast, perceived paternal maltreatment was uniquely related with NSSI's addictive features. Findings underline the importance of studying inter-related family-based risk factors of NSSI simultaneously for a comprehensive understanding of familial correlates of NSSI behavior and its underlying features.

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.

Full Text Available Purpose: This paper is focused on an analysis and evaluation of severe events according to their frequency of occurrence and their impact on the company's manufacturing and distribution supply chains performance in the Czech Republic. Risk factors are introduced for critical events.Design/methodology: An identification and classification of severe events are realized on the basis of median mapping and mapping of ordinal variability acquired through the questionnaire survey of 82 companies. Analysis of 46 risk factors was sorted into 5 groups. We used asymmetric Somers's d statistics for testing the dependence of frequency and impact of a severe event on selected risk sources. The hierarchical cluster analysis is performed to identify relatively homogeneous groups of critical severe events according to their dependency on risk factors and its strength.Findings: Results showed that ‘a lack of contracts’ is considered to be the most critical severe event. Groups of demand and supply side and an external risk factor group were identified to be the most significant sources of risk factors. The worst cluster encompasses 11% of examined risk factors which should be prevented. We concluded that organizations need to adopt appropriate precautions and risk management methods in logistics.Originality: In this paper, the methodology for severe events evaluation in supply chain is designed. This methodology involves assessing the critical factors which influence the critical events and which should be prevented.

the influence of eprosartan. The antihypertensive effect of eprosartan against SBP was independent of the presence/absence of obesity in patients with EH. Eprosartan resulted in a significant increase in the maximum linear velocity in the left internal carotid artery by 2.8 % and in the vertebrobasilar region by 24.3 %. The total power of the spectrum under the influence of treatment significantly increased by 14.3 %. Antihypertensive therapy with telmisartan within half a year causes a significant decrease in "office" SBP by 24.8 %, DBP by 20.0 %, PBP by 31.8 %, avg. BP by 22.2 % In patients with EH who have/do not have the status of smoker and in all 100 % of patients with normal and elevated total cholesterol telmisartan was equally effective in achieving the target level of SBP. Obesity or its absence also did not significantly affect the effectiveness of antihypertensive therapy with telmisartan in patients with EH. Telmisartan, like eprosartan, causes regression of left ventricular hypertrophy. Telmisartan has a positive effect on carotid blood flow and does not affect the blood flow of the vertebrobasilar region. There were no changes in the parameters of the vegetative balance under the influence of telmisartan. Conclusion. In patients with EH with additional factors of cardiovascular risk using both eprosartan and telmisartan for half a year is accompanied by a significant decrease in blood pressure, regression of myocardial hypertrophy and improvement of diastolic function of the left ventricle, improvement of blood flow in the carotid region. In contrast to telmisartan, eprosartan increases the total power of the heart rate variability spectrum and does not affect the level of total cholesterol. The influence of telmisartan on the blood flow in the vertebrobasilar region is absent. Smoking, obesity, hypercholesterolemia do not reduce the antihypertensive efficacy of telmisartan and eprosartan against SBP and DBP. However, eprosartan is less effective in

Myocardial flow reserve (MFR) measurement has an important role in assessing the functional severity of coronary artery stenosis. However, a discrepancy between the anatomical severity of coronary artery stenosis and MFR is often observed. Such a discrepancy may be explained by coronary risk factors. In this study, we aimed to investigate the influence of coronary artery stenosis severity and risk factors on MFR. Seventy-four patients suspected to have coronary artery disease and seven age-matched healthy volunteers were enrolled. Myocardial blood flow (MBF) and MFR were measured using 15 O-labelled water PET. Regional MFR was calculated in regions with significant coronary artery stenosis (stenotic regions) and in regions without significant stenosis (remote regions). The contributions of coronary artery stenosis severity and coronary risk factors were assessed using univariate and multivariate analyses. In stenotic regions, MFR correlated inversely with coronary artery stenosis severity (r=-0.50, p<0.01). Univariate analysis did not show any significant difference in MFR between the patients with and the patients without each risk factor. In remote regions, however, MFR was significantly decreased in the diabetes and smoking groups (each p<0.05). By multivariate analysis, diabetes and smoking were independent predictors of MFR (each p<0.05). In the group with more than one risk factor, MFR was significantly lower (2.78±0.79) than in the other group (3.40±1.22, p<0.05). MFR is influenced not only by coronary stenosis severity but also by coronary risk factors. In particular, the influence of risk factors should be considered in regions without severe coronary stenosis. (orig.)

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.

Full Text Available Abstract Background Maternal age is a known risk factor for stillbirth and delayed childbearing is a societal norm in developed country settings. The timing and reasons for age being a risk factor are less clear. This study aimed to document the gestational specific risk of maternal age throughout pregnancy and whether the underlying causes of stillbirth differ for older women. Methods Using linkage of state maternity and perinatal death data collections the authors assessed risk factors for antepartum stillbirth in New South Wales Australia for births between 2002 – 2006 (n = 327,690 using a Cox proportional hazards model. Gestational age specific risk was calculated for different maternal age groups. Deaths were classified according to the Perinatal Mortality Classifications of the Perinatal Society of Australia and New Zealand. Results Maternal age was a significant independent risk factor for antepartum stillbirth (35 – 39 years HR 1.4 95% CI 1.12 – 1.75; ≥ 40 years HR 2.41 95% CI 1.8 – 3.23. Other significant risk factors were smoking HR 1.82 (95% CI 1.56 –2.12 nulliparity HR 1.23 (95% CI 1.08 – 1.40, pre-existing hypertension HR 2.77 (95% CI 1.94 – 3.97 and pre-existing diabetes HR 2.65 (95% CI 1.63 – 4.32. For women aged 40 or over the risk of antepartum stillbirth beyond 40 weeks was 1 in 455 ongoing pregnancies compared with 1 in 1177 ongoing pregnancies for those under 40. This risk was increased in nulliparous women to 1 in 247 ongoing pregnancies. Unexplained stillbirths were the most common classification for all women, stillbirths classified as perinatal infection were more common in the women aged 40 or above. Conclusions Women aged 35 or older in a first pregnancy should be counselled regarding stillbirth risk at the end of pregnancy to assist with informed decision making regarding delivery. For women aged 40 or older in their first pregnancy it would be reasonable to offer induction of labour by 40 weeks

In 2003, the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) published a set of risk factors for amblyopia. The intent was to promote uniformity of reporting and development in screening. Because this prevalence is not yet known, this meta-analysis is an attempt to estimate it. Major community preschool eye examination studies were reviewed and AAPOS cut-offs estimated. The approximate prevalence of anisometropia is 1.2%, hyperopia is 6%, astigmatism is 15%, myopia is 0.6%, strabismus is 2.5%, and visual acuity less than 20/40 is 6%. The mean combined prevalence is 21% ± 2% compared to a prevalence of amblyopia 20/40 and worse of 2.5%. Knowing risk factor prevalence simplifies validation efforts. Amblyopia screening with a risk factor sensitivity less than 100% is expected and desirable. Copyright 2013, SLACK Incorporated.

Colonic diverticular disease is a common illness, especially in the elderly population. It may be asymptomatic and cause chronic intestinal problems, colonic diverticular bleeding or inflammatory complications with considerable morbidity and mortality. We have attempted at finding factors that would help us identify patients with a higher risk of diverticulitis recurrence as well as patients with a higher likelihood of perforated diverticulitis. This retrospective study included all patients admitted to our surgical ward for inflammatory complications of diverticular disease between 2000 and 2012: 278 patients, 88 men and 190 women. We looked up the first attack of diverticulitis in our documentation as well as the relapses, if any, their number and course, and the time from the first attack to the relapse. We analyzed the influence of age, gender, comorbidities (diabetes mellitus, overweight, ischemic heart disease, chronic renal failure, gastroduodenal disease), nicotine abuse and medication (glucocorticoids and other immunosuppressive drugs, acetylsalicylic acid) on diverticulitis recurrence and its complicated course. We compared the results of conservative and surgical therapy. Statistical analysis was performed using Fishers exact test and Man-Whitney U tests. We did not demonstrate any statistically significant dependence of diverticulitis recurrence on age or gender. Colectomy (both acute and elective surgery) clearly decreases the likelihood of recurrence (p=0.00007). Comorbidities, nicotine abuse and medication were not associated with an increased risk of recurrence. Steroid and immunosuppressive drugs use was significantly associated with higher perforation rates, without impacting on the likelihood of recurrence. Regular smoking of cigarettes had no impact on recurrence or on its severity. We did not find any reliable indicator of recurrent diverticulitis. Age, gender, comorbidities, smoking and medication are not significant. Immunocompromised
Acute renal failure post-cardiac surgery (RF) is a major complication and is associated with increased postoperative morbidity and mortality. Early recognition and identification of risk factors for RF is therefore important. However, several definitions of RF are used. The intention of this study is to evaluate if the used definitions influence the incidence and the identification of risk factors for RF. We identified, after exclusion of 13 patients with preoperative dialysis, 995 consecutive patients undergoing cardiac surgery at the UMC St. Radboud Medical Center between January 2009 and 15 February 2010 as our study cohort. Apart from the definition used by the Society of Thoracic Surgeons, we selected five major international studies concerning RF, each using a different RF definition. These six definitions were used to evaluate the incidence of and identification of risk factors for RF in our study cohort. There is not only a statistically significant difference in incidence (range 4.94-38.1%) of RF between the definitions (p definition several common but also several different risk variables. Multivariate analysis identified also different independent predictors, with different odds ratios for RF for each definition. This study shows that the used definition of RF influences not only the incidence of RF, but also patient identification and the identification of risk variables.

Full Text Available Background: Supply chains in South Africa operate in a challenging business environment. This environment influences the efficiency and effectiveness of South African businesses and supply chains. These factors further influence the competitiveness of products produced in the country, the economic growth and development of South Africa. Objectives: The purpose of this study was two-fold: Firstly, to obtain insight into the main business environment risks and other factors, from a logistics perspective; and secondly, to demonstrate the use of methodology not often used in logistics research − the sequential mixed method. Method: The explorative study was conducted amongst logistics service providers and cargo owners in 2013 by means of a sequential mixed method study, consisting of a survey to determine the importance of risk factors in the business environment, followed by a qualitative study in the form of a focus group discussion to obtain richer data and insight into these risks and factors. The results of these two methods were integrated with industry literature. Results: It was found that increasing transportation costs, operational management of infrastructure and human resources-related problems pose the biggest challenges in the logistics industry. In addition, it was found that the mixed method research study has application possibilities in logistics research. Conclusion: The factors identified as particularly problematic for the logistics industry, namely ineffective operational management of infrastructure, the general conditions in the labour market and increasing costs (to some extent are outside the control of individual organisations. However, organisations can control how they react and mitigate these risk factors. It is shown that these factors and risks can change overnight. The use of the explorative mixed method in obtaining qualitative and quantitative inputs and integrating it with existing literature proved to be a

Chronic mucus hypersecretion (CMH) is highly prevalent in smokers and associated with an accelerated lung function decline and chronic obstructive pulmonary disease (COPD). Several risk factors contribute to CMH and to COPD. It is, however, unknown if risk factors for CMH are similar in persons with and without COPD. 1479 persons with and 8529 without COPD, participating in the general population-based LifeLines cohort, completed questionnaires and underwent spirometry. Occupational exposure was assessed using the ALOHA+ job exposure matrix. Analyses were performed using multiple logistic regression models. In COPD, a significantly higher risk for CMH was associated with higher pack-years smoking (per 10 pack-years) (OR=1.28; 1.12 to 1.46) and environmental tobacco smoke (ETS) (OR=2.06; 1.33 to 3.19). In non-COPD; male gender (OR=1.91; 1.51 to 2.41), higher Body Mass Index (OR=1.04; 1.01 to 1.06), higher pack-years smoking (OR=1.28; 1.14 to 1.44), current smoking (OR=1.50; 1.04 to 2.18), low and high exposure to mineral dust (OR=1.39; 1.04 to 1.87 and OR=1.60; 1.02 to 2.52), high exposure to gases & fumes (OR=2.19; 1.49 to 3.22). Significant interactions were found between COPD and exposure to gases & fumes (p=0.018) and aromatic solvents (p=0.038). A higher risk for CMH was associated with higher pack-years smoking regardless of COPD status. However, a higher risk for CMH was associated with high occupational exposure to gases & fumes in individuals without COPD only.

The underlying cause for postmastectomy pain syndrome (PMPS) and its impact on quality of life remain unclear. The objective of this study aims to determine retrospectively the prevalence of PMPS, its predicting risk factors, and its impact on quality of life. In this survey, 225 women completed a battery of questionnaires. The questionnaires comprised the short form of the McGill Pain Questionnaire (SF-MPQ) exploring the characteristics and the description of the pain, and a Short Form-36 (SF-36) Health Survey evaluating quality of life. Logistic regression analyses were subsequently performed to identify risk factors for PMPS. 62 women (27.6%) reported PMPS as a consequence of surgery, and the pain was generally mild, mostly localized in breast area and intermittent. The pain was mainly described as aching (62.9%). 144 women reported sensory disturbance. We found that only the younger age is the predictive factor for PMPS (P < 0.05). Compared to the patients who did not experience PMPS, those who suffered from PMPS had significantly worse scores in role limitations due to physical problems (role physical, RP), body pain (BP), general health (GH), vitality (VT), role limitations due to emotional problems (role emotional, RE), and mental health (MH) (P < 0.05). PMPS is a significant problem, and the possible risk factors should be further explored. Patients with PMPS have significant worse quality of life, suggesting that patients should be well informed about the likelihood of experiencing the pain, and they may be afforded greater predictability and higher perceived control to enhance their quality of life.

Perioperative anaphylactic as well as anaphylactoid reactions can be elicited by drugs, diagnostic agents, antiseptics, disinfectants and latex. In some individuals, allergic reactions occur in the absence of any evident risk factor. Previous history of specific safe exposure to a product does not permit to exclude the risk of having a reaction. We have systematically reviewed characteristics in the patient's history or clinical parameters that affect the risk of developing reactions during anesthesia. Evidence shows that patients with previous unexplained reaction during anesthesia are at risk for perioperative allergic reactions. An allergic reaction to an agent is associated with previous reaction to a product that is related with the culprit agent. Multiple surgery procedures, professional exposure to latex and allergy to fruit are associated with an increased frequency of latex allergy. It has been shown that in some instances, allergic perioperative reactions may be more common in atopic patients and in females.

Patients undergoing treatment for head and neck cancer may develop myofascial pain syndrome as sequelae. The purpose of this study was to determine the prevalence, risk factors, and quality of life (QOL) related to myofascial pain syndrome. This was a prospective study including patients with head and neck cancer with at least a 1-year disease-free interval. One hundred sixty-seven patients were analyzed, and myofascial pain syndrome was diagnosed in 20 (11.9%). In the multivariate analysis, hypopharyngeal tumors (odds ratio [OR] = 6.35; 95% confidence interval [CI] = 1.58-25.56) and neck dissection (OR = 3.43; 95% CI = 1.16-10.17) were independent factors for myofascial pain syndrome. The pain (p < .001) and shoulder domain (p < .001) as well as overall University of Washington Quality of Life (UW-QOL) score (p = .006) were significantly lower in the patients with myofascial pain syndrome. Myofascial pain syndrome was observed in 1 of 9 patients after head and neck cancer treatment and a worse QOL was observed among them. Tumor site and neck dissection were found to be risk factors for myofascial pain syndrome. © 2014 Wiley Periodicals, Inc.

The purpose of this article is to examine the aspects of collegiate environments, rather than student characteristics, that influence drinking. Unfortunately, the existing literature is scant on this topic. A literature review of articles primarily published within the last 10 years, along with some earlier "landmark" studies of collegiate drinking in the United States, was conducted to determine institutional factors that influence the consumption of alcohol. In addition, a demonstration analysis of Core Alcohol and Drug Survey research findings was conducted to further elucidate the issues. Several factors have been shown to relate to drinking: (1) organizational property variables of campuses, including affiliations (historically black institutions, women's institutions), presence of a Greek system, athletics and 2- or 4-year designation; (2) physical and behavioral property variables of campuses, including type of residence, institution size, location and quantity of heavy episodic drinking; and (3) campus community property variables, including pricing and availability and outlet density. Studies, however, tend to look at individual variables one at a time rather than in combination (multivariate analyses). Some new analyses, using Core Alcohol and Drug Survey data sets, are presented as examples of promising approaches to future research. Given the complexities of campus environments, it continues to be a challenge to the field to firmly establish the most compelling institutional and environmental factors relating to high-risk collegiate drinking.

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

Most studies of risk factors for new low back pain (LBP) have been conducted in Western populations, but because of cultural and environmental differences, the impact of causal factors may not be the same in other countries. We used longitudinal data from the Cultural and Psychosocial Influences on Disability (CUPID) study to assess risk factors for new onset of disabling LBP among Japanese workers. Data came from a 1-year prospective follow-up of nurses, office workers, sales/marketing personnel, and transportation workers, initially aged 20-59 years, who were employed in or near Tokyo. A baseline questionnaire included items on past history of LBP, personal characteristics, ergonomic work demands, and work-related psychosocial factors. Further information about LBP was collected at follow-up. Analysis was restricted to participants who had been free from LBP during the 12 months before baseline. Logistic regression was used to assess baseline risk factors for new onset of disabling LBP (i.e. LBP that had interfered with work) during the 12 months of follow-up. Among 955 participants free from LBP during the 12 months before baseline, 58 (6.1%) reported a new episode of disabling LBP during the 12-month follow-up period. After mutual adjustment in a multivariate logistic regression analysis, which included the four factors that showed associations individually (p 3.0). When past history of LBP was excluded from the model, ORs for the remaining risk factors were virtually unchanged. Our findings suggest that among Japanese workers, as elsewhere, past history of LBP is a major risk factor for the development of new episodes of disabling back pain. They give limited support to the association with occupational lifting that has been observed in earlier research, both in Japan and in Western countries. In addition, they suggest a possible role of long working hours, which merits further investigation.
Full Text Available Dementia is a complex human disease. The incidence of dementia among the elderly population is rising rapidly worldwide. In the United States, Alzheimer's disease (AD is the leading type of dementia and was the fifth and eighth leading cause of death in women and men aged ≥ 65 years, respectively, in 2003. In Taiwan and many other counties, dementia is a hidden health issue because of its underestimation in the elderly population. In Western countries, the prevalence of AD increases from 1–3% among people aged 60–64 years to 35% among those aged > 85 years. In Taiwan, the prevalence of dementia for people aged ≥ 65 years was 2–4% by 2000. Therefore, it is important to identify protective and risk factors for dementia to prevent this disease at an early stage. Several factors are related to dementia, e.g. age, ethnicity, sex, genetic factors, physical activity, smoking, drug use, education level, alcohol consumption, body mass index, comorbidity, and environmental factors. In this review, we focus on studies that have evaluated the association between these factors and the risk of dementia, especially AD and vascular dementia. We also suggest future research directions for researchers in dementia-related fields.
Ethics are determined by weighing risks against benefits, pros against cons, but also by evasion. Whenever decisions are taken, the side effects and risks to be accepted must be weighed. In law, this is called the principle of commensurability implying that ethical compromises are made. Too much emphasis on ethical principles leads to an evasion of realistic action. In consensus discussions it is often seen that the positions adopted by science and technology are incommensurable with those of philosophy, psychology, and theology. Any decision requires that the risk be evaluated in a spirit of responsibility. (orig.) [de

Full Text Available Orofacial clefts include cleft lip (CL, cleft palate (CP, and cleft lip and palate (CLP, which combined represent the largest group of craniofacial malformations in humans with an overall prevalence of one per 1,000 live births. Each of these birth defects shows strong familial aggregation, suggesting a major genetic component to their etiology. Genetic studies of orofacial clefts extend back centuries, but it has proven difficult to define any single etiologic mechanism because many genes appear to influence risk. Both linkage and association studies have identified several genes influencing risk, but these differ across families and across populations. Genome-wide association studies have identified almost two dozen different genes achieving genome-wide significance, and there are broad classes of ‘causal genes’ for orofacial clefts: a few genes strongly associated with risk and possibly directly responsible for Mendelian syndromes which include orofacial clefts as a key phenotypic feature of the syndrome, and multiple genes with modest individual effects on risk but capable of disrupting normal craniofacial development under the right circumstances (which may include exposure to environmental risk factors. Genomic sequencing studies are now underway which will no doubt reveal additional genes/regions where variants (sequence and structural can play a role in controlling risk to orofacial clefts. The real challenge to medicine and public health is twofold: to identify specific genes and other etiologic factors in families with affected members and then to devise effective interventions for these different biological mechanisms controlling risk to complex and heterogeneous birth defects such as orofacial clefts.

Stroke is a heterogeneous syndrome, and determining risk factors and treatment depends on the specific pathogenesis of stroke. Risk factors for stroke can be categorized as modifiable and nonmodifiable. Age, sex, and race/ethnicity are nonmodifiable risk factors for both ischemic and hemorrhagic stroke, while hypertension, smoking, diet, and physical inactivity are among some of the more commonly reported modifiable risk factors. More recently described risk factors and triggers of stroke include inflammatory disorders, infection, pollution, and cardiac atrial disorders independent of atrial fibrillation. Single-gene disorders may cause rare, hereditary disorders for which stroke is a primary manifestation. Recent research also suggests that common and rare genetic polymorphisms can influence risk of more common causes of stroke, due to both other risk factors and specific stroke mechanisms, such as atrial fibrillation. Genetic factors, particularly those with environmental interactions, may be more modifiable than previously recognized. Stroke prevention has generally focused on modifiable risk factors. Lifestyle and behavioral modification, such as dietary changes or smoking cessation, not only reduces stroke risk, but also reduces the risk of other cardiovascular diseases. Other prevention strategies include identifying and treating medical conditions, such as hypertension and diabetes, that increase stroke risk. Recent research into risk factors and genetics of stroke has not only identified those at risk for stroke but also identified ways to target at-risk populations for stroke prevention. © 2017 American Heart Association, Inc.
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.

Attention deficit hyperactivity disorder (ADHD) is one of the most common childhood psychiatric disorders. Severity of symptoms is associated with more behavioral problems, poor academic performance, and persistence of symptoms into adulthood. To examine the clinical and social correlates that may be identified as risk factors associated with ADHD severity in a sample of adolescent ADHD school students. A total of 925 students were recruited from two public and two private schools from eastern Cairo. They were interviewed using Conners-Wells Adolescent Self-Report-short version (CASS-S); students scoring more than 65 were further interviewed with Kiddie Schedule for Affective Disorders and Schizophrenia-present and lifetime version (K-SADS-PL) to confirm the diagnosis, then Conners-Wells Adolescent Self-Report-long version (CASS-L) to assess severity and Wechsler Intelligence Scale for Children (WISC) to ascertain intellectual ability. About 10.3% of cases were severe, 5.7% were moderate, and 83.9% were mild. Severity was significantly associated with female gender, psychiatric comorbidity, family problems, conduct symptoms, and poor anger management. Diagnostic and Statistical Manual of Mental Disorders (4th ed.) ( DSM-IV) hyperactive-impulsive type was the only predictive factor of ADHD severity. The diagnosis of hyperactive-impulsive subtype may predict the severity of ADHD symptoms.

The role of the lifetime number of ovulatory cycles has not been evaluated in the context of BRCA-associated ovarian cancer. Thus, we conducted a matched case-control study to evaluate the relationship between the cumulative number of ovulatory cycles (and contributing components) and risk of developing ovarian cancer in BRCA mutation carriers (1,329 cases and 5,267 controls). Information regarding reproductive and hormonal factors was collected from a routinely administered questionnaire. Conditional logistic regression was used to evaluate all associations. We observed a 45% reduction in the risk of developing ovarian cancer among women in the lowest vs. highest quartile of ovulatory cycles (OR = 0.55; 95% CI 0.41-0.75, p = 0.0001). Breastfeeding for more than 12 months was associated with a 38% (95% CI 0.48-0.79) and 50% (95% CI 0.29-0.84) reduction in risk among BRCA1 and BRCA2 mutation carriers, respectively. For oral contraceptive use, maximum benefit was seen with five or more years of use among BRCA1 mutation carriers (OR = 0.50; 95% CI 0.40-0.63) and three or more years for BRCA2 mutation carriers (OR = 0.42; 95% CI 0.22-0.83). Increasing parity was associated with a significant inverse trend among BRCA1 (OR = 0.87; 95% CI 0.79-0.96; p-trend = 0.005) but not BRCA2 mutation carriers (OR 0.98; 95% CI 0.81-1.19; p-trend = 0.85). A later age at menopause was associated with an increased risk in women with a BRCA1 mutation (OR trend = 1.18; 95% CI 1.03-1.35; p = 0.02). These findings support an important role of breastfeeding and oral contraceptive use for the primary prevention of ovarian cancer among women carrying BRCA mutations. © 2014 UICC.

This study was performed to identify the prevalence, influence, and risk factors associated with chronic pain among Japanese industry workers. We investigated 2,544 participants working at a manufacturing company A, a manufacturing company B, and 16 branch shops of a retail chain company C. The participants responded to self-administered questionnaires related to pain. Furthermore, data obtained from the lifestyle interview sheet of an annual health screening examination and those obtained from the questionnaires were merged. We analyzed the association between lifestyles, psychosocial factors, and chronic pain. Age- and sex-adjusted odds ratios were calculated with a 95% confidence interval using the logistic regression model. Of 2,544 participants, 1,914 (1,224 men and 690 women) completed the questionnaire, and the response rate was 75.2%. The prevalence of chronic pain over 3 months was 42.7% and that of chronic pain with work disability was 11.3%. A higher proportion of obesity, smoking habit, insomnia, psychological stress, depressive state, workaholic nature, low social support from supervisors and coworkers, high job demand, low job control, and job dissatisfaction was observed in workers with chronic pain than in workers without pain. Several risk factors of chronic pain in Japanese industry workers were found. Obesity, smoking habits, sleep disorders, workplace environment, and mental state should be taken into account as risk factors associated with chronic pain issues and general occupational health.

Neonatal asphyxia is the third leading cause of neonatal death and main cause of long-term neurodevelopmental handicap throughout the world. Prevention is more important than treatment. Most previous reports are limited to retrospective investigations of the relationships between some prenatal risk factors and low Apgar scores. This study was designed to prospectively investigate the relationship between prenatal risk factors and neonatal asphyxia and the influence of single or multiple risk factors on the incidence of neonatal asphyxia, and examine significant risk factors for neonatal asphyxia. From April 2002 through October 2004, a total of 10 376 live-born newborns were enrolled. Forty-six prenatal risk factors were investigated. Neonatal asphyxia was diagnosed based on the following four items: 1. 1-min Apgar score asphyxia was analyzed. The significant risk factors were screened by single logistic regression analysis and forward stepwise conditional multiple logistic regression analysis, with enrolled threshold alphaor=0.10 and pasphyxia occurred in 117 cases (1.13%) out of the 8 530 cases. In the 1 846 cases without risk factors, none had asphyxia (x2=25.6, pasphyxia increased with increasing numbers of risk factors, from 0.23% in newborns with one risk factor to 14.29% in newborns who had nine risk factors (r=0.96, pasphyxia by systematically examining prenatal risk factors and giving interventions for the newborns with risk factors, especially those with the above significant risk factors or with multiple risk factors. Proper cesareon section according to indications might be helpful to decrease the incidence of birth asphyxia.

Suicide rates amongst schizophrenic patients are high. There are disadvantages in investigating successfully completed suicides which make suicidal ideation and previous attempts important proxy measures of suicidal risk. The aim of this study was to investigate factors associated with these risk measures. Fifty-nine patients suffering recent onset schizophrenia were assessed for suicidal ideation and history, and a range of demographic, clinical, social (including relatives' Expressed Emotion) and self-esteem measures. Univariate comparisons were made between those with and without suicide ideation and previous attempts. Path analysis was conducted to identify factors directly or indirectly associated with a composite scale of risk (low, medium or high). Approximately 25% of the sample reported a current desire to kill themselves and 47% had made one or more previous attempts. There were numerous significant univariate differences between those with or without ideation or history. Path analysis indicated that greater hopelessness (OR 1.22) and longer duration of illness (OR 1.13) increased risk. Hopelessness was associated with higher negative self-evaluation and social isolation. Negative self-evaluation was associated with more relatives' criticism which was associated with more negative symptoms. Being a male, unmarried and unemployed were all significantly associated with an increase in negative symptoms. Social isolation was associated with being unemployed, older, more positive symptoms and longer illness duration. Duration of illness was not itself predicted by any other variables. Non-fatal suicide ideation and behaviour are significantly associated with an array of demographic, clinical, interpersonal and psychological factors. To reduce risk of suicide, these factors need to be assessed and methods developed to reduce their influence.
Full Text Available Central corneal thickness (CCT, one of the most highly heritable human traits (h(2 typically>0.9, is important for the diagnosis of glaucoma and a potential risk factor for glaucoma susceptibility. We conducted genome-wide association studies in five cohorts from Australia and the United Kingdom (total N = 5058. Three cohorts were based on individually genotyped twin collections, with the remaining two cohorts genotyped on pooled samples from singletons with extreme trait values. The pooled sample findings were validated by individual genotyping the pooled samples together with additional samples also within extreme quantiles. We describe methods for efficient combined analysis of the results from these different study designs. We have identified and replicated quantitative trait loci on chromosomes 13 and 16 for association with CCT. The locus on chromosome 13 (nearest gene FOXO1 had an overall meta-analysis p-value for all the individually genotyped samples of 4.6x10(-10. The locus on chromosome 16 was associated with CCT with p = 8.95x10(-11. The nearest gene to the associated chromosome 16 SNPs was ZNF469, a locus recently implicated in Brittle Cornea Syndrome (BCS, a very rare disorder characterized by abnormal thin corneas. Our findings suggest that in addition to rare variants in ZNF469 underlying CCT variation in BCS patients, more common variants near this gene may contribute to CCT variation in the general population.

In this study, we examined longitudinal, person-centered trajectories of acculturation, internalizing symptoms, and self-esteem in 349 Latino adolescents. We compared acculturation measures (time in the US, culture-of-origin involvement, US cultural involvement, for both parents and adolescents); acculturation stressors (perceived discrimination, acculturation conflicts); and family dynamics (parent-adolescent conflict, familism). Results indicated that, over time, Latino adolescents' internalizing problems decreased and their self-esteem increased. However, we showed that increased length of time living in the US was significantly related to lower self-esteem among adolescents. Parent-adolescent conflict was a strong risk factor, which not only directly heightened internalizing symptoms and lowered self-esteem, but also mediated the effects of acculturation conflicts and perceived discrimination on these outcomes. Our findings revealed familism as a cultural asset associated with fewer internalizing symptoms and higher self-esteem. Internalizing symptoms were also minimized by the adolescent's involvement in the US culture whereas bicultural adolescents with high culture-of-origin involvement reported higher self-esteem. We discussed the limitations and implications of this study for future research and practice.

Aristolochic acids (AAs) widely exist in such plants as Aristolochia and Asarum. The renal toxicity of AAs as well as its carcinogenicity to urinary system have been widely known. In 2003 and 2004, China prohibited the use of Aristolochiae Radix, Aristolochiae Manshuriensis Caulis and Aristolochiae Fangchi Radix, and required administering other AAs-containing medicines in accordance with the regulations for prescription drugs. In this paper, we retrieved literatures on the content determination of AAs in recent 10 years in China. It suggested that the AAs content is lower in Asarum herb, especially in its roots and rhizomes, and most of which do not show detectable amount of AA-I. Some of traditional Chinese medicines show fairly small amount of detectable AA-I. The AAs content in Aristolochia herb (including Fructus Aristolochiae, kaempfer dutchmanspipe root) is relatively high; however, there are fewer literatures for studying the content determination of AAs in Chinese patent medicines. There were many factors affecting AAs content, including the parts used, origins, processing methods, extraction process. It suggested that we should pay attention to the toxicity of Chinese medicines containing AAs and use these decoction pieces and traditional Chinese medicines cautiously. In addition, basic studies for the origins, processing methods and extraction process of Chinese patent medicines containing AAs, as well as supervision and detection of AAs content in traditional Chinese medicinal materials, decoction pieces and Chinese patent medicines shall be strengthened for reducing medication risk and guaranteeing clinical medication safety.

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

Patients with chronic kidney disease (CKD) who had peptic ulcer bleeding (PUB) may have more adverse outcomes. This population-based cohort study aimed to identify risk factors that may influence the outcomes of patients with CKD and PUB after initial endoscopic hemostasis. Data from 1997 to 2008 were extracted from the National Health Insurance Research Database in Taiwan. We included a cohort dataset of 1 million randomly selected individuals and a dataset of patients with CKD who were alive in 2008. A total of 18,646 patients with PUB were screened, and 1229 patients admitted for PUB after endoscopic hemostasis were recruited. The subjects were divided into non-CKD (n = 1045) and CKD groups (n = 184). We analyzed the risks of peptic ulcer rebleeding, sepsis events, and mortality among in-hospital patients, and after discharge. Results showed that the rebleeding rates associated with repeat endoscopic therapy (11.96% vs 6.32%, P = 0.0062), death rates (8.7%, vs 2.3%, P < 0.0001), hospitalization cost (US$ 5595±7200 vs US$2408 ± 4703, P < 0.0001), and length of hospital stay (19.6 ± 18.3 vs 11.2 ± 13.1, P < 0.0001) in the CKD group were higher than those in the non-CKD group. The death rate in the CKD group was also higher than that in the non-CKD group after discharge. The independent risk factor for rebleeding during hospitalization was age (odds ratio [OR], 1.02; P = 0.0063), whereas risk factors for death were CKD (OR, 2.37; P = 0.0222), shock (OR, 2.99; P = 0.0098), and endotracheal intubation (OR, 5.31; P < 0.0001). The hazard ratio of rebleeding risk for aspirin users after discharge over a 10-year follow-up period was 0.68 (95% confidence interval [CI]: 0.45-0.95, P = 0.0223). On the other hand, old age (P < 0.0001), CKD (P = 0.0090), diabetes (P = 0.0470), and congestive heart failure (P = 0.0013) were the independent risk factors for death after discharge. In-hospital patients with CKD and PUB after endoscopic therapy

Antibiotic-associated diarrhea (AAD) and Clostridium difficile infection (CDI) are well-known outcomes from antibiotic administration. Because emergency department (ED) visits frequently result in antibiotic use, we evaluated the frequency of AAD/CDI in adults treated and discharged home with new prescriptions for antibiotics to identify risk factors for acquiring AAD/CDI. This prospective multicenter cohort study enrolled adult patients who received antibiotics in the ED and were discharged with a new prescription for antibiotics. Antibiotic-associated diarrhea was defined as 3 or more loose stools for 2 days or more within 30 days of starting the antibiotic. C difficile infection was defined by the detection of toxin A or B within this same period. We used multivariate logistic regression to assess predictors of developing AAD. We enrolled and followed 247 patients; 45 (18%) developed AAD, and 2 (1%) developed CDI. Patients who received intravenous (IV) antibiotics in the ED were more likely to develop AAD/CDI than patients who did not: 25.7% (95% confidence interval [CI], 17.4-34.0) vs 12.3% (95% CI, 6.8-17.9). Intravenous antibiotics had adjusted odds ratio of 2.73 (95% CI, 1.38-5.43), and Hispanic ethnicity had adjusted odds ratio of 3.04 (95% CI, 1.40-6.58). Both patients with CDI had received IV doses of broad-spectrum antibiotics. Intravenous antibiotic therapy administered to ED patients before discharge was associated with higher rates of AAD and with 2 cases of CDI. Care should be taken when deciding to use broad-spectrum IV antibiotics to treat ED patients before discharge home. Copyright © 2014 Elsevier Inc. All rights reserved.

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.

Meat intake has been consistently shown to be positively associated with incident type 2 diabetes. Part of that association may be mediated by body iron status, which is influenced by genetic factors. We aimed to test for interactions of genetic and dietary factors influencing body iron status in relation to the risk of incident type 2 diabetes. The case-cohort comprised 9,347 case subjects and 12,301 subcohort participants from eight European countries. Single nucleotide polymorphisms (SNPs) were selected from genome-wide association studies on iron status biomarkers and candidate gene studies. A ferritin-related gene score was constructed. Multiplicative and additive interactions of heme iron and SNPs as well as the gene score were evaluated using Cox proportional hazards regression. Higher heme iron intake (per 1 SD) was associated with higher ferritin levels (β = 0.113 [95% CI 0.082; 0.144]), but not with transferrin (-0.019 [-0.043; 0.006]) or transferrin saturation (0.016 [-0.006; 0.037]). Five SNPs located in four genes (rs1799945 [ HFE H63D], rs1800562 [ HFE C282Y], rs236918 [ PCK7 ], rs744653 [ SLC40A1 ], and rs855791 [ TMPRSS6 V736A]) were associated with ferritin. We did not detect an interaction of heme iron and the gene score on the risk of diabetes in the overall study population ( P add = 0.16, P mult = 0.21) but did detect a trend toward a negative interaction in men ( P add = 0.04, P mult = 0.03). We found no convincing evidence that the interplay of dietary and genetic factors related to body iron status associates with type 2 diabetes risk above the level expected from the sum or product of the two individual exposures. © 2017 by the American Diabetes Association.

Osteonecrosis of the jaw (ONJ) is an adverse effect that is associated with bisphosphonate (BP) use. Little data are available on risk factors influencing the time of treatment until an osteonecrosis occurs. From 1 Dec 2004 until 21 Sep 2012, the German Register collected all patients with validated diagnoses of ONJ (N = 1,229) that were reported to the national pharmaco-vigilance system or to the Register directly. We analysed 963 patients with cancerous disease and an ONJ during i.v. BP treatment. Duration of BP treatment until first diagnosis of ONJ and Kaplan-Meier curves of ONJ-free survival were analysed stratified by gender, type of BP and type of cancer. Main indications for BP treatment were breast cancer (36%), multiple myeloma (24%), prostate cancer (16%) and kidney cancer (4%). Men suffered from their ONJ earlier than women. A total of 780 patients (81%) had their ONJ during zoledronate treatment, 93 (10%) under pamidronate and 90 (9%) under ibandronate treatment. ONJ-free survival in single BP users was significantly longer in pamidronate-treated patients than in zoledronate or ibandronate users. Ibandronate users had the shortest median duration of treatment (17 months), similar to that of zoledronate users (21.5 months). Sequential prescription of two different BPs prolonged the period of overall BP treatment until an ONJ occurred. Time of BP treatment was shortest in patients with kidney cancer. Age or a concomitant osteoporosis did not influence the time to event of an ONJ. Systemic risk factors such as gender play a significant role in certain subgroups only. Comparative analysis of different cancer patients helps the treating oncologist/dentist to identify patients with a more imminent risk to develop an ONJ (i.e. kidney cancer, ibandronate/zoledronate use).

To define influence of the comorbidity diseases and risk factors of development of the combined peptic ulcer of a stomach and duodenum. As a result of carried-out poll and inspection 250 patients with an exacerbation of a peptic ulcer were surveyed. Patients were distributed in 3 groups of observation depending on localization of ulcerative process. At all surveyed questioning was carried out, data on hereditary load, smoking, alcohol intake, existence of somatopathies were specified, clinic-morphological implications of a peptic ulcer were studied. The peptic ulcer of a stomach is characteristic for women (72.1%) and develops mainly aged from 45 till 59 years (60.3%). Peptic ulcer of duodenum men (76.3%) suffer mainly, the debut is the share in most cases of age from 18 to 44 years (79.1%). The combined canker of a stomach and duodenum meets at males (61.2%) more often, is initially involved in process ulcerogenesis by duodenum generally aged from 30 till 44 years (64.2%), accession of a canker of a stomach happens is delayed (at 38.8% within 16 and more years). In the analysis of risk factors at patients with the combined peptic ulcer of a stomach and duodenum depending on existence or absence specific to this category of patients of a background from such comorbidity diseases as IBS, HOBL and widespread osteochondrosis taped that larger prevalence of smoking (100%) and as the use (50%) and the excessive use (50%), alcohol are characteristic for the patients having a high comorbidity (a combination of three above nosologies). The greatest interest in respect of possible communication with formation of the combined peptic ulcer of a stomach and duodenum is represented by IBS, HOBL and osteochondrosis. And major factors of risk were smoking, the excessive alcohol intake, the burdened heredity.

One goal in identifying psychosocial risk factors is to discover opportunities for intervention. The purpose of this review is to examine psychosocial risk factors for disordered eating, placing research findings in the larger context of how etiological models for eating disorders can be transformed into models for intervention. A qualitative literature review was conducted focusing on psychological and social factors that increase the risk for developing eating disorders, with an emphasis on well-replicated findings from prospective longitudinal studies. Epidemiological, cross-cultural, and longitudinal studies underscore the importance of the idealization of thinness and resulting weight concerns as psychosocial risk factors for eating disorders. Personality factors such as negative emotionality and perfectionism contribute to the development of eating disorders but may do so indirectly by increasing susceptibility to internalize the thin ideal or by influencing selection of peer environment. During adolescence, peers represent self-selected environments that influence risk. Peer context may represent a key opportunity for intervention, as peer groups represent the nexus in which individual differences in psychological risk factors shape the social environment and social environment shapes psychological risk factors. Thus, peer-based interventions that challenge internalization of the thin ideal can protect against the development of eating pathology. Copyright © 2013 Wiley Periodicals, Inc.

Full Text Available The measurement and analysis of heart rate variability (HRV, which is based on the variation between consecutive NN intervals, has become an established procedure over the past two decades. A decrease in HRV has been shown to correlate with an increase in mortality. HRV is influenced by a number of physiological factors such as various diseases. Awareness of these mediators or confounders is of great importance in the analysis and assessment of HRV both in scientific studies and in clinical practice. This document, which is based on a selective survey of references and supplemented by information from national and international guidelines, presents the main endogenous, exogenous and constitutional factors. A decrease in HRV has been observed not only in connection with non-influenceable physiological factors such as age, gender and ethnic origin, but also in conjunction with a large number of acute and chronic diseases. Numerous lifestyle factors have both a positive and a negative influence on HRV. There are also physical influences that affect HRV. They must on no account be disregarded. Although the list of the factors is long and not all of them have yet been fully studied, awareness of them is of crucial importance in the measurement of HRV (both under laboratory conditions and during medical practice, its analysis and its assessment. More research also needs to be carried out to close knowledge gaps.

This study investigates risk and protective factors for substance abuse in a sample of 1778 students attending technical colleges in Bangkok and Nakhon Ratchasima provinces of Thailand using a self-report questionnaire modified from the Communities That Care youth survey. Low school commitment was strongly associated with illicit drug use, with adjusted odds ratios ranging from 2.84 (glue sniffing) to 10.06 (ecstasy). Having friends using drugs, and friends with delinquent behaviors increased the risk of using alcohol and illegal drugs, with adjusted odds ratios of 6.84 and 6.72 respectively for marijuana use. For protective factors, approximately 40-60% of students with high levels of moral belief, participation in religious activities, and social skills were less likely to use alcohol. It is concluded that peer influence is a significant contributor to Thai adolescents' participation in substance abuse and that engaging in religiosity may assist adolescents to internalize negative aspects of harmful drugs into positive perceptions and encourage them to avoid alcohol and illegal drugs.

This study examines the relative influence of race/ethnicity, acculturation, peer substance use, and academic achievement on adolescent substance use among different Asian American ethnic groups and U.S. racial/ethnic groups. Data from the Wave 1 in-home sample of the National Longitudinal Study of Adolescent Health was used to examine lifetime use of alcohol, tobacco, and marijuana in a full adolescent sample of all racial/ethnic groups (N=20,745) and a subsample of Asian American adolescents (N=1,248). Path analysis examined the hypothesized relationships of peer substance use and acculturation as risk factors and academic achievement as a protective factor for racial/ethnic groups. The results indicated that when Asian American adolescents were compared to other major U.S. racial/ethnic groups, peer use and acculturation were both significant mediators of smoking, drinking, and marijuana use, and academic achievement mediated each type of use at a trend level. For Asian American ethnic groups, peer use is a risk factor and, to a lesser extent, academic achievement a protective factor for substance use. Also, although acculturation is a predictor of substance use, when peer use and academic achievement are taken into account, acculturation -- like ethnicity -- no longer predicts use. Mediation analyses indicated that: peer substance use mediates smoking, drinking, and marijuana use; academic achievement does not; and acculturation mediates substance use for some substances and some Asian American ethnic groups. The results are discussed for their implications for understanding how culturally-specific approaches can inform preventive interventions.

The desiccation tolerance of biofouling taxa (adults and early life-stages) was determined under both controlled and 'realistic' field conditions. Adults of the ascidian Ciona spp. died within 24 h. Mortality in the adult blue mussel Mytilus galloprovincialis occurred within 11 d under controlled conditions, compared with 7 d when held outside. The Pacific oyster Crassostrea gigas was the most desiccation-tolerant taxon tested (up to 34 d under controlled conditions). Biofouling orientated to direct sunlight showed faster mortality rates for all the taxa tested. Mortality in Mytilus juveniles took up to 24 h, compared with 8 h for Ciona, with greater survival at the higher temperature (18.5°C) and humidity (~95% RH) treatment combination. This study demonstrated that desiccation can be an effective mitigation method for a broad range of fouling taxa, especially their early life-stages. Further work is necessary to assess risks from other high-risk species such as algae and cyst forming species.

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.

The Air Quality Health Index (AQHI) provides air quality and health information such that the public can implement health protective behaviours (reducing and/or rescheduling outdoor activity) and decrease exposure to outdoor air pollution. The AQHI's health messages account for increased risk associated with "at risk" populations (i.e. young children, elderly and those with pre-existing respiratory and/or cardiovascular conditions) who rely on health care and service providers for guidance. Using Rogers' Diffusion of Innovations theory, our objective with respect to health care and service providers and their respective "at risk" populations was to explore: 1) level of AQHI knowledge; 2) factors influencing AQHI adoption and; 3) strategies that may increase uptake of AQHI, according to city divisions and socioeconomic status (SES). Semi-structured face-to-face interviews with health care (Registered Nurses and Certified Respiratory Educators) and service providers (Registered Early Childhood Educators) and focus groups with their respective "at risk" populations explored barriers and facilitators to AQHI adoption. Participants were selected using purposive sampling. Each transcript was analyzed using an Interpretive Description approach to identify themes. Analyses were informed by Rogers' Diffusion of Innovations theory. Fifty participants (6 health care and service providers, 16 parents, 13 elderly, 15 people with existing respiratory conditions) contributed to this study. AQHI knowledge, AQHI characteristics and perceptions of air quality and health influenced AQHI adoption. AQHI knowledge centred on numerical reliance and health protective intent but varied with SES. More emphasis on AQHI relevance with respect to health benefits was required to stress relative advantage over other indices and reduce index confusion. AQHI reporting at a neighbourhood scale was recognized as addressing geographic variability and uncertainty in perceived versus measured air

To identify child feeding behavior and household hygiene practices that are risk factors for prolonged diarrheal illness, a longitudinal community study was conducted over a 14-month period among 920 children aged 3-37 months who lived in an urban slum settlement in Nairobi, Kenya. Morbidity surveillance was done by home visits every third day in the absence of diarrhea and daily during diarrheal illness until termination of the episode. In-home observations were made to characterize maternal hygiene, cooking, and child feeding practices. Overall, 1,496 episodes of diarrhea were detected. The average diarrheal incidence was 3.5 episodes/child-year, and the incidence of diarrhea > 14 days was 3 episodes/100 child-years. Cox regression was used to examine the independent effects of covariates on time to recovery from a diarrheal episode. Adjusted behavioral factors that were observed to influence recovery from diarrhea included: uncovered water containers (rate ratio (RR) = 0.77, 95% confidence interval (CI) 0.64-0.94); giving no fluids (as opposed to oral rehydration solutions (ORS)/sugar salt solutions (SSS)) (RR = 1.42, 95% CI 1.14-1.77); and administration of diluted cow's milk during the first 3 days of an episode (RR = 1.23, 95% CI 1.00-1.52). These associations remained significant after adjusting for diarrheal severity. The authors recommend, among other measures, improvement of water storage and promotion of continued feeding with cereal-milk mix during diarrhea.

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

Lung cancer is the most common cause of cancer-related death worldwide, killing almost 22,000 people in Poland every year. Low-dose computed tomography (LDCT) is the most promising tool of secondary prophylaxis leading to early detection and thus successful treatment of this malignancy. Knowledge about socio-demographic factors that affect participation in lung cancer early detection programs is essential for the future design and implementation of such programs. Among the 8649 participants of the Pomeranian Lung Cancer Screening Program (PLCSP), 1619 individuals responded to a questionnaire that had been designed to assess socio-demographic data of participants at high risk of developing lung cancer. The survey was conducted on-site after reception of results by the program participants. Among the survey participants, 777 (48%) were current cigarette smokers. The majority of them represented low or medium level of wealth status. The respondents positively evaluated the promotional campaign during the PLCSP, although 43% of them indicated family and friends as a source of information about the program. As the most important action that stimulated the participation, 46% of the respondents indicated the awareness campaign involving a celebrity, and 45% of them indicated the presence of cancer in the family. The influence of healthcare employees on the participation in the screening program was minimal. More than half of the respondents (53%) declared a willingness to co-finance a similar prophylactic program in the future in an amount not exceeding 100 PLN. An effective promotional campaign in the media, the influence of family and a campaign involving a celebrity promoted attendance at the screening program. The influence of healthcare employees on the participation in the program was minimal. The majority of the screened population declared a willingness to actively participate in the costs of LDCT examination.
Full Text Available The purpose of this study is to identify the factors that influence the creation of new businesses and to point out both the differences and the similarities existing between countries and groups of countries in terms of these influencing factors. We are mainly interested in the place Romania and Bulgaria have among the countries of the world from the perspective of entrepreneurial spirit and its influencing factors. To capture the level of business formation we use New business density from World Bank Doing business. Drawing on the existing literature we consider for our analysis several indicators related to economic environment such as GDP per capita, unemployment rate, inflation rate, the level of taxes, foreign direct investments and public debt and indicators describing the quality of governance. The research uses 2014 data for 67 countries, from all development categories, collected from Heritage Foundation database. The research results obtained with principal components analysis show that good governance results in higher levels of GDP per capita and income taxes and the increase of the level of business formation. Also, good governance leads to a decrease in inflation and unemployment. Furthermore, the hierarchical cluster analysis is used to identify groups of countries and to outline similarities and differences between them.

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.

Many researches on risk perception have often been concerned with reaction of the public to modern technology. A major concern is the public fear of such new technology as nuclear power and genetic engineering. When the perceived risk was examined using a risk ranking technique, Japanese school teachers, university students and also NIRS staffs (female clerical staffs and researchers) viewed nuclear power to be much riskier than the objective estimation. Many technical experts have believed that this great fear results from an overestimation of risk by the public due to lack of scientific knowledge. So far, several studies reported the results to examine the correlation of the perception of some risk sources with knowledge about them, although their conclusions are inconsistent. When the perceived risk by trainees on a radiation protection course in NIRS was examined, nuclear power was rated as the second and 14th among 30 risk items by those who majored in life sciences in college and by those in physics, chemistry or technology, respectively. The perceived risk of nuclear power did not change among trainees by training offered fundamental knowledge about radiation during the course. On the other hand, the orders of smoking and alcoholic beverages rose considerably. Our results are consistent with the previous reports, i.e., what people learn initially about risk source has more important role in risk perception than what they learn later, and the increase of perceived risk is more easier than its decrease. Knowledge is now recognized as one of the factors which influence on risk perception. However, a special emphasis is now placed on risk communication in order to make partnership between communicators and receivers in the risk management. (author)

Full Text Available Background The main purpose of this study was to identify factors that influence healthcare quality in the Iranian context. Methods Exploratory in-depth individual and focus group interviews were conducted with 222 healthcare stakeholders including healthcare providers, managers, policy-makers, and payers to identify factors affecting the quality of healthcare services provided in Iranian healthcare organisations. Results Quality in healthcare is a production of cooperation between the patient and the healthcare provider in a supportive environment. Personal factors of the provider and the patient, and factors pertaining to the healthcare organisation, healthcare system, and the broader environment affect healthcare service quality. Healthcare quality can be improved by supportive visionary leadership, proper planning, education and training, availability of resources, effective management of resources, employees and processes, and collaboration and cooperation among providers. Conclusion This article contributes to healthcare theory and practice by developing a conceptual framework that provides policy-makers and managers a practical understanding of factors that affect healthcare service quality.

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

The accuracy of self-report data may be marred by a range of cognitive and motivational biases, including social desirability response bias. The current study used qualitative interviews to examine self-report response biases among participants in a large randomized clinical trial in Vietnam. A sample of study participants was reinterviewed. The vast majority reported being truthful and emphasized the importance of rapport with the study staff for achieving veridical data. However, some stated that rapport may lead to under reporting of risk behaviors in order not to disappoint study staff. Other factors that appeared to influence accuracy of self-reports include fear that the information may be divulged, desire to enroll in the study, length of the survey, and memory. There are several methods that can be employed to reduce response biases, and future studies should systematically address response bias and include methods to assess whether approaches and survey items are effective in improving accuracy of self-report data.

This complex and unique sport requires athletes to appropriately distribute their speed or energy expenditure (ie, pacing within each discipline as well as over the entire event. As with most physical activity, the regulation of pacing in triathlon may be influenced by a multitude of intrinsic and extrinsic factors. The majority of current research focuses mainly on the Olympic distance, whilst much less literature is available on other triathlon distances such as the sprint, half-Ironman, and Ironman distances. Furthermore, little is understood regarding the specific physiological, environmental, and interdisciplinary effects on pacing. Therefore, this article discusses the pacing strategies observed in triathlon across different distances, and elucidates the possible factors influencing pacing within the three specific disciplines of a triathlon.

The longer psychotic disorders are untreated the worse their prognosis. Increasing the awareness of early psychosis by professionals who come into regular contact with young people is one strategy that could reduce treatment delay. As teachers engage with students on a daily basis, their role could be exploited to increase awareness of the early signs of psychosis. This study employed the Theory of Planned Behaviour (TPB) to identify and measure factors that influence identification of students at high-risk (HR) of developing psychosis in 16+ educational institutions. An elicitation phase revealed beliefs underlying teachers' motivations to detect HR students and informed the construction of a preliminary 114-item questionnaire incorporating all constructs outlined in the TPB. To define the determinants of teachers' intention to identify HR students, 75 teachers from secondary and further education institutions in 12 counties surrounding Cambridgeshire completed the questionnaire. A psychometric model of item response theory was used to identify redundant items and produce a reduced questionnaire that would be acceptable to teachers. The final instrument comprised 73 items and showed acceptable reliability (α = 0.69-0.81) for all direct measures. Teacher's confidence and control over identification of HR students was low. Although identification of HR students was considered worthwhile, teachers believed that their peers, students and particularly their managers might not approve. Path analysis revealed that direct measures of attitude and PBC significantly predicted intention, but subjective norm did not. PBC was the strongest predictor of intention. Collectively, the direct measures explained 37 % of the variance of intention to identify HR for psychosis. This research demonstrated how the TPB can be used to identify and measure factors that influence identification of students at HR of developing psychosis in 16+ educational institutions and confirmed the

Full Text Available Colorectal cancer (CRC is a major health problem worldwide. Although population-based CRC screening is strongly recommended in average-risk population, compliance rates are still far from the desirable rates. High levels of screening uptake are necessary for the success of any screening program. Therefore, the investigation of factors influencing participation is crucial prior to design and launches a population-based organized screening campaign. Several studies have identified screening behaviour factors related to potential participants, providers, or health care system. These influencing factors can also be classified in non-modifiable (i.e., demographic factors, education, health insurance, or income and modifiable factors (i.e., knowledge about CRC and screening, patient and provider attitudes or structural barriers for screening. Modifiable determinants are of great interest as they are plausible targets for interventions. Interventions at different levels (patient, providers or health care system have been tested across the studies with different results. This paper analyzes factors related to CRC screening behaviour and potential interventions designed to improve screening uptake.

Bone is the single most frequent site for bone metastasis in breast cancer patients. Patients with bone-only metastasis have a fairly good prognosis when compared with patients with visceral disease. Nevertheless, cancer-induced bone disease carries an important risk of developing skeletal related events that impact quality of life (QoL). It is therefore particularly important to stratify patients according to their risk of developing bone metastasis. In this context, several risk factors have been studied, including demographic, clinicopathological, genetic, and metabolic factors. Most of them show conflicting or non-definitive associations and are not validated for clinical use. Nonetheless, tumour intrinsic subtype is widely accepted as a major risk factor for bone metastasis development and luminal breast cancer carries an increased risk for bone disease. Other factors such as gene signatures, expression of specific cytokines (such as bone sialoprotein and bone morphogenetic protein 7) or components of the extracellular matrix (like bone crosslinked C-telopeptide) might also influence the development of bone metastasis. Knowledge of risk factors related with bone disease is of paramount importance as it might be a prediction tool for triggering the use of targeted agents and allow for better patient selection for future clinical trials.

Full Text Available An increasing number of countries are requiring an extended learner permit prior to independent driving. The question of when drivers begin the learner permit period, and how long they hold the permit before advancing to independent licensure has received little research attention. Licensure timing is likely to be related to “push” and “pull” factors which may encourage or inhibit the process. To examine this question, we recruited a sample of 90 novice drivers (49 females and 41 males, average age of 15.6 years soon after they obtained a learner permit and instrumented their vehicles to collect a range of driving data. Participants completed a series of surveys at recruitment related to factors that may influence licensure timing. Two distinct findings emerged from the time-to-event analysis that tested these push and pull factors in relation to licensure timing. The first can be conceptualized as teens’ motivation to drive (push, reflected in a younger age when obtaining a learner permit and extensive pre-permit driving experience. The second finding was teens’ perceptions of their parents’ knowledge of their activities (pull; a proxy for a parents’ attentiveness to their teens’ lives. Teens who reported higher levels of their parents’ knowledge of their activities took longer to advance to independent driving. These findings suggest time-to-licensure may be related to teens’ internal motivation to drive, and the ability of parents to facilitate or impede early licensure.

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.
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)
Full Text Available The aim of the study was to determine the correlation between risk factors and diabetic retinopathy, which is the leading cause of blindness in developed countries for patients aged 20 to 65.We compared risk factors between patients without retinopathy, with non-proliferate and with proliferate retinopathy (p< 0.05. Duration of diabetes is most important for the development of retinopathy. Hyperglycaemia and high blood pressure are important for progression. Better control of blood sugar and elevated blood pressure can reduce progression of retinopathy and riskof vision loss.

Surveillance of chronic kidney disease (CKD) prevalence over time and information on how changing risk factors influence this trend are needed to evaluate the effects of general practice and public health interventions. Because very few studies addressed this, we studied the total adult population of a demographically stable county representative of Norway using cross-sectional studies 10 years apart (Nord-Trøndelag Health Study (HUNT)2 and Nord-Trøndelag Health Study (HUNT)3, 65,237 and 50,586 participants, respectively). Thorough quality-control procedures and comparisons of methods over time excluded analytical drift, and multiple imputations of missing data combined with nonattendance weights contributed to unbiased estimates. CKD prevalence remained stable in Norway from 1995 through 1997 (11.3%) to 2006 through 2008 (11.1%). The association of survey period with CKD prevalence was modified by a strong decrease in blood pressure, more physical activity, and lower cholesterol levels. Without these improvements, a 2.8, 0.7, and 0.6 percentage points higher CKD prevalence could have been expected, respectively. In contrast, the prevalence of diabetes and obesity increased moderately, but the proportion of diabetic patients with CKD decreased significantly (from 33.4% to 28.6%). A CKD prevalence of 1 percentage point lower would have been expected without these changes. Thus, CKD prevalence remained stable in Norway for more than a decade in association with marked improvements in blood pressure, lipid levels, and physical activity and despite modest increases in diabetes and obesity.

(1) Angiogenesis (growth of new capillaries from an existing capillary bed) may result from a mismatch in microvascular supply and metabolic demand (metabolic error signal). Krogh examined the distribution and number of capillaries to explore the correlation between O(2) delivery and O(2) consumption. Subsequently, the heterogeneity in angiogenic response within a muscle has been shown to reflect either differences in fibre type composition or mechanical load. However, local control leads to targetted angiogenesis in the vicinity of glycolytic fibre types following muscle stimulation, or oxidative fibres following endurance training, while heterogeneity of capillary spacing is maintained during ontogenetic growth. (2) Despite limited microscopy resolution and lack of specific markers, Krogh's interest in the structure of the capillary wall paved the way for understanding the mechanisms of capillary growth. Angiogenesis may be influenced by the response of perivascular or stromal cells (fibroblasts, macrophages and pericytes) to altered activity, likely acting as a source for chemical signals modulating capillary growth such as vascular endothelial growth factor. In addition, haemodynamic factors such as shear stress and muscle stretch play a significant role in adaptive remodelling of the microcirculation. (3) Most indices of capillarity are highly dependent on fibre size, resulting in possible bias because of scaling. To examine the consequences of capillary distribution, it is therefore helpful to quantify the area of tissue supplied by individual capillaries. This allows the spatial limitations inherent in most models of tissue oxygenation to be overcome generating an alternative approach to Krogh's tissue cylinder, the capillary domain, to improve descriptions of intracellular oxygen diffusion. © 2010 The Author.

Human behavior, rational or irrational one, influences one of the most complex markets worldwide: the insurance market. In most situations, insurance markets are not competitive and risk neutral insurers negotiate under asymmetric information with actors who exhibit risk aversion. In this paper we develop a game theory model that analyzes the negotiation of an insurance contract under risk aversion conditions (in static and dynamic approach). Risk aversion influence was introduced in the mode...

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.

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

Research on youth mental health has increasingly indicated the importance of multivariate analyses of multiple risk factors for negative outcomes. Television and video game use have often been posited as potential contributors to attention problems, but previous studies have not always been well-controlled or used well-validated outcome measures. The current study examines the multivariate nature of risk factors for attention problems symptomatic of attention deficit hyperactivity disorder and poor school performance. A predominantly Hispanic population of 603 children (ages 10-14) and their parents/guardians responded to multiple behavioral measures. Outcome measures included parent and child reported attention problem behaviors on the Child Behavior Checklist (CBCL) as well as poor school performance as measured by grade point average (GPA). Results found that internal factors such as male gender, antisocial traits, family environment and anxiety best predicted attention problems. School performance was best predicted by family income. Television and video game use, whether total time spent using, or exposure to violent content specifically, did not predict attention problems or GPA. Television and video game use do not appear to be significant predictors of childhood attention problems. Intervention and prevention efforts may be better spent on other risk factors.

Full Text Available In addition to HPV, high parity and hormonal contraceptives have been associated with cervical cancer (CC. However, most of the evidence comes from retrospective case-control studies. The aim of this study is to prospectively evaluate associations between hormonal factors and risk of developing cervical intraepithelial neoplasia grade 3 (CIN3/carcinoma in situ (CIS and invasive cervical cancer (ICC.We followed a cohort of 308,036 women recruited in the European Prospective Investigation into Cancer and Nutrition (EPIC Study. At enrollment, participants completed a questionnaire and provided serum. After a 9-year median follow-up, 261 ICC and 804 CIN3/CIS cases were reported. In a nested case-control study, the sera from 609 cases and 1,218 matched controls were tested for L1 antibodies against HPV types 11,16,18,31,33,35,45,52,58, and antibodies against Chlamydia trachomatis and Human herpesvirus 2. Multivariate analyses were performed to estimate hazard ratios (HR, odds ratios (OR and corresponding 95% confidence intervals (CI. The cohort analysis showed that number of full-term pregnancies was positively associated with CIN3/CIS risk (p-trend = 0.03. Duration of oral contraceptives use was associated with a significantly increased risk of both CIN3/CIS and ICC (HR = 1.6 and HR = 1.8 respectively for ≥ 15 years versus never use. Ever use of menopausal hormone therapy was associated with a reduced risk of ICC (HR = 0.5, 95%CI: 0.4-0.8. A non-significant reduced risk of ICC with ever use of intrauterine devices (IUD was found in the nested case-control analysis (OR = 0.6. Analyses restricted to all cases and HPV seropositive controls yielded similar results, revealing a significant inverse association with IUD for combined CIN3/CIS and ICC (OR = 0.7.Even though HPV is the necessary cause of CC, our results suggest that several hormonal factors are risk factors for cervical carcinogenesis.

Optimal sperm cryopreservation is a prerequisite for the sustainable commercial application of frozen-thawed boar semen for AI. Three experiments were performed to identify factors influencing variability of postthaw sperm survival among 464 boar ejaculates. Sperm-rich ejaculate fractions were cryopre-served using a standard freezing-thawing procedure for 0.5-mL plastic straws and computer-controlled freezing equipment. Postthaw sperm motility (assessed with a computer-assisted semen analysis system) and viability (simultaneously probed by flow cytometry analysis after triple-fluorescent stain), evaluated 30 and 150 min postthaw, were used to estimate the success of cryopreservation. In the first experiment, 168 unselected ejaculates (1 ejaculate/boar), from boars of 6 breeds with a wide age range (8 to 48 mo), were cryopreserved over a 12-mo period to evaluate the predictive value of boar (breed and age), semen collection, transport variables (season of ejaculate collection, interval between collections, and ejaculate temperature exposure), initial semen traits, and sperm quality before freezing on sperm survival after freezing-thawing. In Exp. 2, 4 ejaculates from each of 29 boars, preselected according to their initial semen traits and sperm quality before freezing, were collected and frozen over a 6-mo period to evaluate the influence of interboar and intraboar ejaculate variability in the survival of sperm after cryopreservation. In Exp. 3, 12 ejaculates preselected as for Exp. 2, from each of 15 boars with known good sperm cryosurvival, were collected and frozen over a 12-mo period to estimate the sustainability of sperm cryosurvival between ejaculates over time. Boar and semen collection and transport variables were not predictive of sperm cryosurvival among ejaculates. Initial semen traits and sperm quality variables observed before freezing explained 23.2 and 10.9%, respectively, of the variation in postthaw sperm motility and viability. However, more that
Influence able and Avoidable Risk Factors for Systemic Air Embolism due to Percutaneous CT-Guided Lung Biopsy: Patient Positioning and Coaxial Biopsy Technique-Case Report, Systematic Literature Review, and a Technical Note
Rott, G.; Boecker, F.
Following the first case of a systemic air embolism due to percutaneous CT-guided lung biopsy in our clinic we analysed the literature regarding this matter in view of influence able or avoidable risk factors. A systematic review of literature reporting cases of systemic air embolism due to CT-guided lung biopsy was performed to find out whether prone positioning might be a risk factor regarding this issue. In addition, a technical note concerning coaxial biopsy practice is presented. Prone position seems to have relevance for the development and/or clinical manifestation of air embolism due to CT-guided lung biopsy and should be considered a risk factor, at least as far as lesions in the lower parts of the lung are concerned. Biopsies of small or cavitary lesions in coaxial technique should be performed using a hemo static valve.

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.

Partially bilingual physicians may weigh a number of factors in deciding whether to use their own limited non-English language skills or call an interpreter when caring for patients with limited English proficiency. Yet little is known about this decision process or how it might fail. In a patient safety approach to exploration of this complex, potentially high-stakes decision, key risk factors that may contribute to miscommunication during health care encounters in non-English languages were identified. The Healthcare Failure Mode and Effects Analysis (HFMEA) method was adapted to examine the decision process. An initial set of possible decision factors was presented to a national expert panel of eight physicians, who modified and expanded the list of factors and then rated each according to four scales: Frequency, Importance, Amenability to Intervention, and Detectability. A "5 Whys" approach was used to examine underlying causes of these failure modes and generate potential interventions. Nine factors were described that could lead physicians to use their own skills rather than an interpreter when that decision might pose unacceptable risk. The highest-priority factor was lack of knowledge regarding the value of using a trained interpreter and how to work with a trained interpreter effectively. For the top failure mode, a sample hypothetical 5 Whys exercise shows how to examine potential underlying causes and produce recommendations. A variety of discrete factors can have important effects on physicians' decisions to use their own non-English language skills or an interpreter. Because this decision can affect patient safety, organizations and policy makers should use these factors to guide local efforts to examine these issues and develop quality improvement and safety activities.

Full Text Available Tubal ligation is one of the most effective and reliable methods of contraception and of successful program of birth control in Iran. Present study was done to evaluate factors affecting risk of complications during tubal ligation surgery. We studied 1780 women that had tubal ligation in 13 hospitals in Tehran during the years 1993-95. Data on operation were collected by questionnaire and analyzed using logistic regression method. Risk of complications was increased in women had had operation after vaginal therapy, in luteal phase, after cesarean section and in follicular phase, respectively. Modified pomery, pomery and parkland methods of operation were ascendingly related to increased risk of complications. Age, history of pelvic pain, method of anesthesia, incision size and time of operation were not significantly correlated with complications. Frequency of complications was higher in women that had other procedures during surgery. We suggest that tubal ligation be done after vaginal delivery and by modified pomery method.

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

While cohort studies have revealed a range of risk factors for coronary heart disease and stroke, the extent to which the strength of these associations varies according to duration of follow-up in studies with extended disease surveillance is unclear. This was the aim of the present study. Initiated in 1967/70, the original Whitehall study is an on-going cohort study of 15,402 male UK government workers free of coronary heart disease when they took part in a baseline medical examination during which a range of standard risk factors was measured. In analyses in which we stratified by duration of follow-up, there was evidence of time-dependency for most risk factor-disease relationships. Thus, the associations of systolic and diastolic blood pressure, total cholesterol and cigarette smoking with coronary heart disease and stroke diminished in strength with increasing duration of follow-up, whereas the magnitude of the body mass index-coronary heart disease relation was unchanged. For example, the age-adjusted hazard ratios (95% confidence interval) for cigarette smoking (versus never smoked) in relation to coronary heart disease were: 2.49 (1.80, 3.44), 1.65 (1.34, 2.03), 1.36 (1.15, 1.61) and 1.32 (1.10, 1.58) for follow-up periods 0-10, 10-20, 20-30 and 30+ years, respectively. Despite a general diminution in the strength of effect over time, even in the fourth decade of follow-up, classic risk factors retained some predictive capacity for coronary heart disease and, to a lesser degree, stroke. © The European Society of Cardiology 2014.

Full Text Available Abstract Background We sought to understand the multilevel syndemic factors that are concurrently contributing to the HIV epidemic among women living in the US. We specifically examined community, network, dyadic, and individual factors to explain HIV vulnerability within a socioecological framework. Methods We gathered qualitative data (120 interviews and 31 focus groups from a subset of women ages 18–44 years (N = 2,099 enrolled in the HPTN 064 HIV seroincidence estimation study across 10 US communities. We analyzed data from 4 diverse locations: Atlanta, New York City (the Bronx, Raleigh, and Washington, DC. Data were thematically coded using grounded theory methodology. Intercoder reliability was assessed to evaluate consistency of team-based coding practices. Results The following themes were identified at 4 levels including 1 exosystem (community: poverty prevalence, discrimination, gender imbalances, community violence, and housing challenges; 2 mesosystem (network: organizational social support and sexual concurrency; 3 microsystem (dyadic: sex exchange, interpersonal social support, intimate partner violence; and 4 individual: HIV/STI awareness, risk taking, and substance use. A strong theme emerged with over 80 % of responses linked to the fundamental role of financial insecurity underlying risk-taking behavioral pathways. Conclusions Multilevel syndemic factors contribute to women’s vulnerability to HIV in the US. Financial insecurity is a predominant theme, suggesting the need for tailored programming for women to reduce HIV risk. Trial registration Clinicaltrials.gov, NCT00995176

Birth asphyxia is an insult to the fetus or newborn due to failure to breath or breathing poorly, leads to decrease oxygen perfusion to various organs. According to WHO, 4 million neonatal deaths occurred each year due to birth asphyxia. Our goal was to evaluate antepartum, intrapartum, and fetal risk factors of birth asphyxia. It was a Retrospective Case control study, conducted at Neonatal Intensive Care Unit of pediatric ward (I, II, III) and in Gynecology wards (I, II, III) of Civil Hospital Karachi, Dow University of Health Sciences. Study was conducted from January 2011-November 2012. Neonates diagnosed with birth asphyxia were considered as "cases" while neonates born either with normal vaginal delivery or by cesarean section having no abnormality were considered as "control". Demographics of both the mother and neonate were noted and Questions regarding possible risk factors were asked from mother. Ethical issues were confirmed from Institutional review board of Civil Hospital Karachi, Dow University of Health Sciences. All data was entered and analyzed through SPSS 19. Out of total 240 neonates, 123 were "cases" and 117 were "control". Mean maternal age in "case" group was 24.22 ± 3.38 while maternal age of control group was 24.30 ± 4.04. Significant antepartum risk factors were maternal age of 20-25 (OR 0.30 CI 95% 0.07-1.21), booking status (OR 0.20 CI 95% 0.11-0.37), pre-eclampsia (OR 0.94 CI 95% 0.90-0.98) and primigravidity (OR 2.64 CI 95% 1.56-4.46). Significant Intrapartum risk factors were breech presentation (OR 2.96 CI 95% 1.25-7.02), home delivery (OR 16.16 CI 95% 3.74-69.75) and maternal fever (OR 10.01 CI95% 3.78-26.52). Significant Fetal risk factors were resuscitation of child (OR 23 CI 95% 31.27-1720.74), pre-term babies(OR 0.34 CI 95% 0.19-0.58), fetal distress (OR 0.01 CI 95% 0.00-0.11) and baby weight (OR 0.13 CI 95% 0.05-0.32). Measures should be taken to prevent neonatal mortality with great emphasis on skilled attendance at birth

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.

In this review, we discuss current evidence linking environmental pollutants to cardiovascular disease (CVD). Extensive evidence indicates that environmental factors contribute to CVD risk, incidence, and severity. Migrant studies show that changes in the environment could substantially alter CVD risk in a genetically stable population. Additionally, CVD risk is affected by changes in nutritional and lifestyle choices. Recent studies in the field of environmental cardiology suggest that environmental toxins also influence CVD. Exposure to tobacco smoke is paradigmatic of such environmental risk and is strongly and positively associated with increased cardiovascular morbidity and mortality. In animal models of exposure, tobacco smoke induces endothelial dysfunction and prothrombotic responses and exacerbates atherogenesis and myocardial ischemic injury. Similar mechanism may be engaged by other pollutants or food constituents. Several large population-based studies indicate that exposure to fine or ultrafine particulate air pollution increases CVD morbidity and mortality, and the plausibility of this association is supported by data from animal studies. Exposure to other chemicals such as polyaromatic hydrocarbons, aldehydes, and metals has also been reported to elevate CVD risk by affecting atherogenesis, thrombosis, or blood pressure regulation. Maternal exposure to drugs, toxins, and infection has been linked with cardiac birth defects and premature CVD in later life. Collectively, the data support the notion that chronic environmental stress is an important determinant of CVD risk. Further work is required to assess the magnitude of this risk fully and to delineate specific mechanisms by which environmental toxins affect CVD.

Adolescent gun violence is a serious public health issue that disproportionately affects young Black males. Although it has been postulated that differential exposure to childhood risk factors might account for racial differences in adolescent gun carrying, no longitudinal studies have directly examined this issue. We examined whether childhood risk factors indexing neighborhood crime, peer delinquency, and conduct problems predicted the initiation of adolescent gun carrying among a community sample of Black and White boys. Analyses then examined whether racial differences in risk factors accounted for racial differences in gun carrying. Data came from a sample of 485 Black and White boys who were repeatedly assessed from 2nd grade until age 18. Multi-informant data collected across the first 3 years of the study were used to assess neighborhood crime, peer delinquency, and conduct problems. Illegal gun carrying was assessed annually from 5th grade through age 18. Growth curve analyses indicated that children with higher initial levels of conduct problems and delinquent peer involvement, as well as those who increased in conduct problems across childhood, were more likely to carry a gun prior to age 18. Black boys were also more likely to carry guns than Whites. Racial differences were greatly reduced, but not eliminated, after controlling for initial levels of conduct problems and delinquent peer involvement. Findings suggest that early prevention programs designed to reduce adolescent gun violence (including racial disparities in gun violence) should target boys with severe conduct problems and those who affiliate with delinquent peers during elementary school.

Full Text Available Alterations within mesocorticolimbic terminal regions commonly occur with alcohol use disorder (AUD. As pathological drug-seeking behavior may arise as a consequence of alcohol-induced neuroadaptations, it is critical to understand how such changes increase the likelihood of relapse. This report examined resting-state functional connectivity (RSFC using both a seed-based and model-free approach in individuals in treatment for AUD and how dysregulation of network connectivity contributes to treatment outcomes. In order to provide a mechanism by which neural networks promote relapse, interactive effects of mesocorticolimbic connectivity and AUD risk factors in treatment completers and non-completers were examined. AUD group showed stronger RSFC between striatum, insula, and anterior cingulate cortex than controls. Within the AUD group, non-completers compared to completers showed enhanced RSFC between (1 striatum–insula, (2 executive control network (ECN–amygdala, and (3 basal ganglia/salience network and striatum, precuneus, and insula. Completers showed enhanced RSFC between striatum-right dorsolateral prefrontal cortex. Furthermore, completers and non-completers differed in relationships between RSFC and relapse risk factors, where non-completers exhibited positive associations between craving intensity and RSFC of striatum–insula and ECN–amygdala. These findings provide evidence for interactions between corticolimbic connectivity in AUD and craving and establish an important link between network connectivity and dynamic risk factors that contribute to relapse. Results demonstrate that relapse vulnerability is attributed to craving dysregulation manifested by enhanced connectivity in striato-limbic regions and diminished corticostriatal connectivity.

The aim of this study was to determine the effect of dexamethasone and ketolgan on postoperative nausea and vomiting and to evaluate risk factors for postoperative nausea and vomiting. A prospective, double-blind, randomized clinical study was carried out. One hundred fifty-three ASA I-II women undergoing laparoscopic gynecologic operations were randomized into three groups: dexamethasone group (n=51), ketolgan group (n=51), and control group (n=51). Patients in the dexamethasone group were given 4 mg of dexamethasone intravenously before the induction of general anesthesia, the ketolgan group received 30-mg ketolgan intravenously, and control group did not receive any medication. The incidence and severity of postoperative nausea and vomiting were registered 24 hours after the surgery. The incidence of postoperative nausea and vomiting in the dexamethasone group was 13.8%; in the ketolgan group, 37.3%, and in the control group, 58.9% (P=0.026). Patients with a history of migraine suffered from postoperative nausea and vomiting in 70.3% of cases and migraine-free patients in 25.8% of cases (P=0.015). Opioids for postoperative analgesia increased the incidence of postoperative nausea and vomiting as compared with nonsteroidal anti-inflammatory drugs (P=0.00002). Preoperative medication with dexamethasone significantly reduces the incidence of postoperative nausea and vomiting. Avoidance of opioids for postoperative analgesia reduces the incidence of postoperative nausea and vomiting. Migraine and motion sickness are independent risk factors for postoperative nausea and vomiting.

Adolescence is a period of life in which peer relationships become increasingly important. Adolescents have a greater likelihood of taking risks when they are with peers rather than alone. In this study, we investigated the development of social influence on risk perception from late childhood through adulthood. Five hundred and sixty-three participants rated the riskiness of everyday situations and were then informed about the ratings of a social-influence group (teenagers or adults) before rating each situation again. All age groups showed a significant social-influence effect, changing their risk ratings in the direction of the provided ratings; this social-influence effect decreased with age. Most age groups adjusted their ratings more to conform to the ratings of the adult social-influence group than to the ratings of the teenager social-influence group. Only young adolescents were more strongly influenced by the teenager social-influence group than they were by the adult social-influence group, which suggests that to early adolescents, the opinions of other teenagers about risk matter more than the opinions of adults. © The Author(s) 2015.

This study investigated the influence of personality characteristics and gender on adolescents’ perception of risk and their risk-taking behaviour. Male and female participants (157 females: 116 males, aged 13–20) completed self-report measures on risk perception, risk-taking and personality. Male participants perceived behaviours as less risky, reportedly took more risks, were less sensitive to negative outcomes and less socially anxious than female participants. Path analysis identified a model in which age, behavioural inhibition and impulsiveness directly influenced risk perception, while age, social anxiety, impulsiveness, sensitivity to reward, behavioural inhibition and risk perception itself were directly or indirectly associated with risk-taking behaviour. Age and behavioural inhibition had direct relationships with social anxiety, and reward sensitivity was associated with impulsiveness. The model was representative for the whole sample and male and female groups separately. The observed relationship between age and social anxiety and the influence this may have on risk-taking behaviour could be key for reducing adolescent risk-taking behaviour. Even though adolescents may understand the riskiness of their behaviour and estimate their vulnerability to risk at a similar level to adults, factors such as anxiety regarding social situations, sensitivity to reward and impulsiveness may exert their influence and make these individuals prone to taking risks. If these associations are proven causal, these factors are, and will continue to be, important targets in prevention and intervention efforts. PMID:27100081

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.

Bovine tuberculosis (bTB) is a worldwide zoonotic disease of domestic and wild animals. Eradication has proved elusive in those countries with intensive national programmes but with ongoing transmission between wildlife and cattle. In Portugal, a high-risk area for bTB was defined and specific measures implemented to assess and minimize the risk from wildlife. Data from the 2011 to 2014 hunting seasons for red deer (Cervus elaphus) and wild boar (Sus scrofa) were analysed with bovine demographic and bTB information to assess factors that determined the occurrence and distribution of bTB in both species. The likelihood of bTB-like lesions in wild boar was positively associated with density of red deer, wild boar and cattle, while for red deer, only their density and age were significant factors. The likelihood of Mycobacterium bovis isolation in wild boar was associated with density of cattle and red deer and also with the anatomical location of lesions, while for red deer, none of the variables tested were statistically significant. Our results suggest that, in the study area, the role of red deer and wild boar may be different from the one previously suggested by other authors for the Iberian Peninsula, as red deer may be the driving force behind M. bovis transmission to wild boar. These findings may assist the official services and game managing bodies for the management of hunting zones, what could also impact the success of the bTB eradication programme. © 2015 Blackwell Verlag GmbH.
The collective influence of biologic and physical factors that modify risks of radiation-induced cancer introduces uncertainties sufficient to deny precision of estimates of human cancer risk that can be calculated for low-dose radiation in exposed populations. The important biologic characteristics include the tissue sites and cell types, baseline cancer incidence, minimum latent period, time-to-tumor recognition, and the influence of individual host (age and sex) and competing etiologic influences. Physical factors include radiation dose, dose rate, and radiation quality. Statistical factors include time-response projection models, risk coefficients, and dose-response relationships. Other modifying factors include other carcinogens, and other biological sources (hormonal status, immune status, hereditary factors).

Introduction The aim is to update and disclose the main environmental risk factors, excluding dietary factors, involved in the etiopathology of prostate cancer. Materials and methods Bibliographic review of the last 25 years of non-dietary environmental risk factors associated with prostate cancer between 1985 and 2010, obtained from MedLine, CancerLit, Science Citation Index and Embase. The search profiles were Environmental Risk Factors/Tobacco/Infectious-Inflammatory Factors/Pesticides/Vasectomy/Occupational Exposures/ Chemoprevention Agents/Radiation and Prostate Cancer. Results While some non-dietary environmental risk factors increase the risk of acquiring the disease, others decrease it. Of the former, it is worth mentioning exposal to tobacco smoke, chronic infectious-inflammatory prostatic processes and occupational exposure to cadmium, herbicides and pesticides. The first factors that reduce the risk are the use of chemopreventive drugs (Finasterida, Dutasteride) and exposure to ultraviolet solar radiation. With the current data, a vasectomy does not influence the risk of developing the disease. Conclusions The slow process of prostate carcinogenesis is the final result of the interaction of constitutional risk and environmental factors. Non-dietary environmental factors play an important role in the etiopathology of this disease. To appropriately assess the risk factors, extensive case studies that include all the possible variables must be analyzed. PMID:21439685

Unintentional injury is the leading cause of death for children and adolescents between the ages of 1 and 18 in the United States, accounting for more deaths than the next 20 causes of mortality combined. It is estimated that pediatric injury accounts for more than $50 billion in annual losses from medical care costs, future wages, and quality of life. Despite these numbers, much remains to be learned about the behavioral risks for pediatric unintentional injury. This article reviews behavioral risk factors for pediatric unintentional injury risk, with a particular focus on four broad areas. First, we discuss the effects of demographic risk factors, including gender, socioeconomic status, and ethnicity. Second, we present information about child-specific risk factors, including temperament, personality, psychopathology, and cognitive development. Third, we discuss the influence of parents and other primary caregivers on childhood injury risk, with a particular focus on the effects of supervision and parenting quality and style. Finally, we discuss the role of peers on child injury risk. We conclude with a discussion of the ways in which the material reviewed has been translated into injury prevention techniques, with a focus on how pediatricians might use knowledge about etiological risk to prioritize safety counseling topics. We also present thoughts on four priorities for future research: injury risk in diverse nations and cultures; developmental effects of injury; the influence of multiple risk factors together on injury risk; and translation of knowledge about risk for injury into intervention and prevention techniques.

At baseline and every 6 months, the patients were assessed with several rating scales, including the Mini-Mental State Examination, Instrumental Activities of Daily Living (IADL, and Physical Self-Maintenance Scale. Doses of ChEI and amounts of HHS per week were recorded. Cox regression models were used to predict the time to HHS, and multiple linear regression was used to predict the volume of HHS used.Results: During the study, 332 patients (38% used HHS. Factors that both postponed HHS use and predicted lower amounts of HHS were higher doses of ChEIs, better IADL ability, and living with family. Men, younger individuals, and those with a slower IADL decline showed a longer time to HHS, whereas female sex, a lower cognitive status, or more medications at baseline predicted fewer hours of HHS.Conclusions: Higher doses of ChEI might reduce the use of HHS, possibly reducing the costs of community-based care. Female spouses provide more informal care than do male spouses, so the likelihood of using HHS is greater among women with AD. The "silent group" of more cognitively impaired and frail elderly AD patients receives less HHS, which might precipitate institutionalization.Keywords: cognition, activities of daily living, treatment effect, gender, predictors
Full Text Available Abstract Background To identify preoperative, perioperative and postoperative risk factors that influence the success of pterygium surgery. Methods This is a prospective study of thirty-six patients with primary or recurrent pterygia. A detailed anamnesis and an ophthalmological examination were performed looking for the following factors: age, race, latitude and altitude of the main place of residence, hours of exposure to the sun, use of protective measures against UV-radiation, classification of pterygium, width of the pterygium at limbus, surgical technique (conjunctival autograft plus suturing versus tissue glue, graft alterations (misapposition, granuloma, haemorrhage, oedema, retraction or necrosis, and postoperative symptoms (foreign-body sensation, pain. The examinations were performed 2 and 7 days and 2, 6 and 12 months after surgery. In addition, recurrence was defined as any growth of conjunctiva into the cornea. Results A logistic regression and a survival analysis have been used to perform data analysis. A total number of 36 patients completed a one year follow-up. A total of 13 patients were born and lived in Spain, and 26 came from other countries, mostly Latin America. A total number of 8 males (no women presented a recurrence, mainly between 2 and 6 months. The hours of sun exposure through their life was independently related to surgical success. Pterygia of less than 5 mm of base width showed a weak positive correlation with recurrence. None of the other factors considered were significantly related to recurrence. Conclusions Male gender and high sun exposure are strongly and independently related to surgical success after the removal of pterygia.

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.

This paper aims to review current knowledge on risk factors leading to burn-out of general practitioners, who are particularly concerned by burn-out, as 50% of them are being more or less affected. This article is based on bibliographic research covering literature between 1975 and 2010, using PUB MED software, medical books and articles. 44 articles were selected as dealing well with the aspects of the burn-out reviewed here. It seems established that stress precedes burnout symptoms. Theories investigating relationships between stress and work are presented. Exogenic stress (load and organization of work, emotional interaction with the patient, constraints, lack of recognition, conflicts between private and professional life) interacts with endogenous stress (idealism, (too much) acute feeling of responsibility, mood disorder, difficulty in collaborating, character, personality). Burn-out symptoms would appear preferentially when these two stresses coexist. Despite the wealth of publications, there is still a lack of knowledge of the causes of burn-out, requiring therefore increased research efforts, in order to improve the implementation of preventive measures, beneficial to the doctors as well as to their patients.

To determine the risk factors associated with polyhydramnios, and assess the maternal and perinatal outcome in these patients. A prospective study of all deliveries complicated with polyhydramnios in Sultan Qaboos University Hospital, Sultanate of Oman between January 2005 and April 2006. Polyhydramnios was divided into mild and moderate to severe based on the amniotic fluid index values. The demographic data, antenatal complications, gestational age at delivery, mode of delivery, postpartum complications, and perinatal outcome were studied. A total of 2648 singleton deliveries occurred during the study period. Two hundred and eight (7.8%) women with polyhydramnios formed the study group, and 2440 women with normal amniotic fluid formed the control. Polyhydramnios was mild in 179 (86.1%) and moderate to severe in 29 (13.9%) cases. Sixty-eight (32.7%) of these pregnancies were complicated with diabetes as compared with 12.4% of the controls. Preterm delivery occurred in 16 (7.7%) cases. Cesarean delivery rate was 27.9% in the study group compared with 17.3% in the control. Major congenital anomalies were found in 2.8% of newborns compared with 1% among the controls. Eighteen babies were admitted to the special care baby unit. These data demonstrates a significant positive relation with maternal age, diabetes in pregnancy, and fetal macrosomia with polyhydramnios. Anemia during pregnancy, cesarean delivery rate, and congenital anomalies were significantly higher in the study group.

The most common cause of poor outcome following lumbar disc surgery is recurrent herniation. Recurrence has been noted in 5% to 15% of patients with surgically treated primary lumbar disc herniation. There have been many studies designed to determine the risk factors for recurrent lumbar disc herniation. In this study, we retrospectively analysed the influence of disc degeneration, endplate changes, surgical technique, and patient's clinical characteristics on recurrent lumbar disc herniation. Patients who underwent primary single-level L4-L5 lumbar discectomy and who were reoperated on for recurrent L4-L5 disc herniation were retrospectively reviewed. All these operations were performed between August 2004 and September 2009 at the Neurosurgery Department of Ataturk Education and Research Hospital in Ankara, Turkey. During the study period, 126 patients were reviewed, with 101 patients underwent primary single-level L4-L5 lumbar discectomy and 25 patients were reoperated on for recurrent L4-L5 disc herniation. Preoperative higher intervertebral disc height (Pdisc herniation had preoperative higher disc height and higher body mass index. Modic endplate changes had a higher tendency for recurrence of lumbar disc herniation. Well-planned and well-conducted large-scale prospective cohort studies are needed to confirm this and enable convenient treatment modalities to prevent recurrent disc pathology.

Mendelian randomisation studies from Asia suggest detrimental influences of alcohol on cardiovascular risk factors, but such associations are observed mainly in men. The absence of associations of genetic variants (e.g. rs671 in ALDH2) with such risk factors in women - who drank little in these populations - provides evidence that the observations are not due to genetic pleiotropy. Here, we present a Mendelian randomisation study in a South Korean population (3,365 men and 3,787 women) that 1...

Background: Re-dislocation after primary treatment of developmental dysplasia of the hip is a serious complication. We analyzed the various risk factors that contribute to re-dislocation, and whether the bony ossific nucleus (ON) confers increased stability against re-dislocation. Materials and Methods: Fifty-five children (60 hips) were classified into three treatment groups: Closed reduction (CR) in 15 children (17 hips), open reduction (OR) in 26 children (28 hips), and OR with bony surgery (ORB) in 14 children (15 hips). The mean age at initial treatment was 16 months (range 6–36 months). Fifty-one hips and 9 hips were Tonnis Grade 4 and 3, respectively. The mean preoperative acetabular index (AI) was 44.82° (range 32°–56°) for the study group. At initial treatment, bony ON was absent in 8 hips and present in 52 hips. Results: No hip developed stiffness and pain after primary treatment. Although the AI index, Tonnis grade, and absence of ossific nucleus were higher in the re-dislocated groups, this was not statistically significant. Excluding the re-dislocations, four children had a fair outcome, 11 had good outcome, and 36 had excellent outcome as per McKay's criteria. In the CR group (17 hips), two children (2 hips) with absent ON had re-dislocation. In the OR group (28 hips), three re-dislocations were seen (three children) at 3, 5, and 7 months, respectively. Two of these had an absent bony ON. In the ORB group (15 hips), one late sub-luxation occurred in a child with absent ON. The mean preoperative AI for the re-dislocated and located group was 44.66° (range 42°–48°) and 44.53° (range 39°–56°), respectively. The postoperative AI was 34.53. Conclusion: The experience of the treating surgeon and technical factors play an overwhelming role in preventing early dislocation. The absence of ON should perhaps alert the surgeon for enhanced spica care, postoperative splinting, and meticulous intra-operative management. PMID:27746489

Vaccination coverage of the first dose of diphtheria-tetanus-pertussis-hepatitis B- Haemophilus influenza type b (pentavalent) vaccine for the City-Province of Kinshasain the years 2012 - 2014 wasbelow the national objective of 92%, with coverage less than 80% reported in 12 of the 35 health zones (HZ). The purpose of this study was to discern potential contributing factors to low vaccination coverage in Kinshasa. We conducted a multi-stage cluster household study of children 6 - 11 months in households residing in their current neighborhood for at least 3 months in the 12 high risk HZ in Kinshasa. Additional information on vaccination status of the children was collected at the health facility. Of the 1,513 households with a child 6-11 months old, 81% were eligible and participated. Among the 1224 children surveyed, 96% had received the first dose of pentavalent vaccine; 84% had received the third dose; and 71% had received all recommended vaccines for their age. Longer travel time to get to health facility (p=0.04) and shorter length of residence in the neighborhood (p=0.04) showed significant differences in relation to incomplete vaccination. Forty percent of children received their most recent vaccination in a facility outside of their HZ of residence. This survey found vaccination coverage in 12 HZs in Kinshasa was higher than estimates derived from administrative reports. The large percentage of children vaccinated outside of their HZ of residence demonstrates the challenge to use of the Reaching Every District strategy in urban areas.

Full Text Available The purpose of this study is to identify the major risk factor domains for gang membership and the relationships of these risk factors to eighth grade students. The domains of risk factors include: individual characteristics, peer group influences, family conditions, school experiences and the community context, along with demographic information obtained from the Student Gang Survey items. Through logistic multiple regression, risk factors associated with school, peer, community-neighborhood, and family were used to predict gang membership. Demographic data were also used as predictor variables. Results indicated that an increase in Community-Neighborhood Risk was associated with a decrease in joining a gang. Non-significant findings for Peer Risk, School Risk, Family Risk and demographic variables are additionally discussed. The current research identifies issues which middle school youth encounter in a county setting; provides a homegrown report to assist stakeholders (administrators, teachers, parents, students, and law enforcement in identifying locally relevant risk factors of gang behavior; and substantiates risk factors for gang membership proliferation in those neighborhoods with no recently documented history of gangs.

The major factor influencing secondary trading for the last few years has been the large contractural commitments built up by consumers for reactor programs which have proven to be unrealistic. The situation has intensified as a result of utilities needing to generate capital through inventory liquidation or reductions. The flexibilities in most contracts are inadequate to match the types of external and/or internal factors faced by the industry. This situation also suggests the need for secondary markets to help the industry adjust to unforeseen difficulties. They are very active markets at this time, but their influence in relation to the long-term method of doing business should not be exaggerated

Full Text Available This paper aims to investigate the relationship between leasing contracts and some factors that influence the value of these contracts. In order to do this, we have decided on some quantitative marketing research by appealing to statistics for accomplishing the objectives that we have set: to find a correlation between the turnover percentage assigned to leasing expenses and several influence factors. This study indicated that the more contracts are signed by a firm, the more likely is to assign a bigger fraction of the income to each new leasing contract. The study confirmed that bigger companies are relying more on leasing as a way of financing than small companies. This study also discovered that companies with more employees are using larger contracts in order to sustain their activity. The findings are expected to contribute to adjusting the offers by the leasing companies, taking into consideration these factors and to using these factors in order to better predict the market evolution.
Full Text Available Agricultural business is a very high-risk job and an increase demand for agricultural products from one side and steady increase in production cost and weather changes, on the other side, have motivated many to use insurance for agricultural products. Insurance plays an important role in influencing crop production and insured satisfaction or farmers. The purpose of this research is to find critical components in agricultural insurance. Based on an exploration of the literature review and interviews, the proposed study of this paper extracts 24 variables and using factor analysis, we select the most important factors, which are grouped in seven categories. The implementation of our factor analysis has revealed uncertainty, moderator, market equilibrium, risky environment, empowering factor, education, training, structural hazards and natural ecosystems as the most important factors influencing agricultural industry.

Cardiac risk scores estimate a patient's risk of future cardiac events or death. They are developed to inform treatment decisions of patients diagnosed with unstable angina or non-ST-elevation myocardial infarction. Despite recommending their use in guidelines and evidence of their prognostic value, they seem underused in practice. The purpose of the study was to gain insight in the motivation for implementing cardiac risk scores, and perceptions of health care practitioners towards the use of these instruments in clinical practice. This qualitative study involved semi-structured interviews with 31 health care practitioners at 11 hospitals throughout the Netherlands. Participants were approached through purposive sampling to represent a broad range of participant- and hospital characteristics, and included cardiologists, medical residents, medical interns, nurse practitioners and an emergency physician. The Pettigrew and Whipp Framework for strategic change was used as a theoretical basis. Data were initially analysed through open coding to avoid forcing data into categories predetermined by the framework. Cardiac risk score use was dependent on several factors, including IT support, clinical relevance for daily practice, rotation of staff and workload. Both intrinsic and extrinsic drivers for implementation were identified. Reminders, feedback and IT solutions were strategies used to improve and sustain the use of these instruments. The scores were seen as valuable support systems in improving uniformity in treatment practices, educating interns, conducting research and quantifying a practitioner's own risk assessment. However, health care practitioners varied in their perceptions regarding the influence of cardiac risk scores on treatment decisions. Health care practitioners disagree on the value of cardiac risk scores for clinical practice. Practitioners driven by intrinsic motivations predominantly experienced benefits in policy-making, education and research

Risk factor management is the key to stroke prevention. Although several studies have assessed the awareness of different risk factors in the general public, there are limited data available on how well acute stroke patients know their own risk factors. The aim of this study was to assess stroke patients' informedness of their own stroke risk factors. All consecutive eligible acute stroke and transient ischemic attack patients hospitalized at the Tartu University Hospital, Department of Neurology, during 9 months in 2010 were interviewed about different stroke risk factors within 72 hours from hospitalization. The respective information was also retrieved from medical records. Of the 341 patients admitted during the study period, 195 were eligible for the interview. Diabetes was the best known risk factor (89%) followed by hypertension (80%), atrial fibrillation (78%), previous stroke (77%), and heart failure and/or ischemic heart disease (66%). We found that acute stroke patients are best informed of their diabetes and worst informed of their ischemic heart disease and/or heart failure. There is, however, room for amelioration in the awareness of all of the studied risk factors. More attention should be addressed to explaining the risks and treatment options to patients at risk of stroke and the general population. Copyright © 2016 National Stroke Association.

The increase in life expectancy has resulted in a high occurrence of dementia and Alzheimer's disease (AD). Research on AD has undergone a paradigm shift from viewing it as a disease of old age to taking a life course perspective. Several vascular, lifestyle, psychological and genetic risk factors influencing this latent period have been recognized and they may act both independently and by potentiating each other. These risk factors have consequently been used to derive risk scores for predicting the likelihood of dementia. Despite population differences, age, low education and vascular risk factors were identified as key factors in all scoring systems. Risk scores can help to identify high-risk individuals who might benefit from different interventions. The European Dementia Prevention Initiative (EDPI), an international collaboration, encourages data sharing between different randomized controlled trials. At the moment, it includes three large ongoing European trials: Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER), Prevention of Dementia by Intensive Vascular Care (preDIVA), and Multidomain Alzheimer Prevention study (MAPT). Recently EDPI has developed a "Healthy Aging through Internet Counseling in Elderly" (HATICE) program, which intends to manage modifiable risk factors in an aged population through an easily accessible Internet platform. Thus, the focus of dementia research has shifted from identification of potential risk factors to using this information for developing interventions to prevent or delay the onset of dementia as well as identifying special high-risk populations who could be targeted in intervention trials.

There is a considerable body of literature on infidelity within romantic relationships. However, there is a gap in the scientific literature on factors influencing the likelihood of uninvolved individuals exposing sexual infidelity. Therefore, we devised an exploratory study examining a wide range of potentially relevant factors. Based in part on evolutionary theory, we anticipated nine potential domains or types of influences on the likelihoods of exposing or protecting cheaters, including kinship, strong social alliances, financial support, previous relationship behaviors (including infidelity and abuse), potential relationship transitions, stronger sexual and emotional aspects of the extra-pair relationship, and disease risk. The pattern of results supported these predictions (N = 159 men, 328 women). In addition, there appeared to be a small positive bias for participants to report infidelity when provided with any additional information about the situation. Overall, this study contributes a broad initial description of factors influencing the predicted likelihood of exposing sexual infidelity and encourages further studies in this area.

Diverticulosis is a very common condition. Around 20% of the carriers of diverticula are believed to suffer from diverticular disease during their lifetime. This makes diverticular disease one of the clinically and economically most significant diseases in gastroenterology. The etiopathogenesis of diverticulosis and diverticular disease is not well understood. Epidemiological studies allow defining risk factors for the development of diverticulitis and its complications. A comprehensive literature search was performed and the current knowledge about risk factors for diverticulitis and associated conditions reviewed. Besides non-controllable risk factors like age and sex, lifestyle factors like food, drinks and physical activity, drugs are described to increase or decrease the risk to develop diverticulitis or to suffer from complications. The recognition of risk factors for the development of diverticular disease or even complicated disease like lifestyle habits or medication is crucial for patient management.

Prospective study of factors influencing conditional discharge from a forensic hospital: the DUNDRUM-3 programme completion and DUNDRUM-4 recovery structured professional judgement instruments and risk.
We set out to examine whether structured professional judgement instruments DUNDRUM-3 programme completion (D-3) and DUNDRUM-4 recovery (D-4) scales along with measures of risk, mental state and global function could distinguish between those forensic patients detained in a secure forensic hospital (not guilty by reason of insanity or unfit to stand trial) who were subsequently discharged by a mental health review board. We also examined the interaction between these measures and risk, need for therapeutic security and eventual conditional discharge.

Females have been underrepresented in the study of science and science careers for decades although advancements have been made in closing this gender gap, the gap persists particularly in the physical sciences. Variables which influence a woman's desire to pursue and maintain a science course of study and career must be discovered. The United States lags behind other industrialized countries in the fields of science, math, and engineering. Females comprise an estimated half of the population; their potential contributions cannot be ignored or overlooked. This retrospective research study explores the personal experiences of ten women enrolled in science majors, with science related career plans. The goal of this study is to describe the factors that influence the participants' interest in science. The findings, the effect of science coursework, science teachers' personality and manner, other influential educational personnel, role models and mentors, external influences exclusive of school, parental influence, locus of control and positive attitudes toward science confirm what other researchers have found.

Full Text Available Racial disparity in preterm is a major problem in the US. Although significant strides have been made in identifying some of the risk factors, the complexities between community and individual factors are not understood. This study examines the influence of individual and community level factors affecting preterm birth among Black and White women in an urban setting. A 10-year live birth registry dataset from a mid-sized, racially diverse city was analyzed (N = 30,591. Data were geocoded and merged with block group level Census data. Five hierarchical models were examined using PROC GLIMMIX. Education, illicit drug use, pregnancy complications, previous preterm birth, paternal presence, inadequate and adequate plus prenatal care, and poverty were associated with preterm births in both Blacks and Whites. In Black women, increasing maternal age, maternal smoking, and a previous infant death were significant predictors of preterm births, which was not the case for White women. Residing in medium or high poverty neighborhoods resulted in 19% and 28% higher odds, respectively, of preterm birth for Black women. In addition to individual level factors, neighborhood poverty is an important risk factor influencing preterm birth. It is essential to engage multisectoral agencies in addressing factors influencing preterm birth.

Full Text Available Bibliometric constructions of "knowledge maps" and "cognitive structures of science" do not differentiate between impact and influence factors. The difference can be constructedaccording to different meaning and interpretation of the terms reference and citation. Reference is "acknowledgment which one author gives to another", whereas citation is "acknowledgment which one document receives from another". Development of Information Science according to period and subject area is analyzed on the corpus of citation literature retrieved from doctoral dissertations in Information Science from 1978 to 2007 at Croatian universities. The research aim is to indicate the difference between document impact factor and author's influence factor (i.e. reference ability to produce effects on actions, behavior, and opinions of authors of doctoral theses. The influence factor serves to distinguish the key role of cited authors in time and according to the duration of the influence (the average age for cited papers of dominant authors in different periods is between eight and ten years. The difference between linear and interactive communication seems vital for the interpretation of cited half-life, i.e. the attitude of one science community towards used information resources and cognitive heritage. The analyzed corpus of 22,210 citations can be divided into three communication phases according to influence factor criteria: in the phase of dialogue and interactive communication 25% of bibliographic units are cited in the first four years; in the second phase another 25% of units are cited from the fifth to the ninth year; after ten years, in the dominant linear communication phase, approximately 30% of units are cited.

The paper deals with the generalized probabilistic approach for analyzing health consequences caused by various exposure factors. Formally basing on the competitive risk theory, it is introduced a general risk model for analysis the influence of environmental risk factors to human health. The usefulness of the model approach is in the opportunity of taking into account: time delay of impact and consequence manifestation; easy comparisons of exposure factors with different nature and various consequences (morbidity and mortality, carcinogenic and genetic); social and environmental components in overall mortality. Preliminary examples of comparative risk analysis are demonstrated on the Russian demography and environmental data with the attempt of characterizing the dynamical tendencies and evolution of introduced risk index. The prospects of the probabilistic approach and the results obtaining on this basis are discussed. (author)
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.

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.

There is a need for a better understanding of exactly how organizational management factors at a nuclear power plant (NPP) affect plant safety performance, either directly or indirectly, and how these factors might be observed, measured, and evaluated. The purpose of this research project is to respond to that need by developing a general methodology for characterizing these organizational and management factors, systematically collecting information on their status and integrating that information into various types of evaluative activities. Research to date has included the development of the Nuclear Organization and Management Analysis Concept (NOMAC) of a NPP, the identification of key organizational and management factors, and the identification of the methods for systematically measuring and analyzing the influence of these factors on performance. Most recently, two field studies, one at a fossil fuel plant and the other at a NPP, were conducted using the developed methodology. Results are presented from both studies highlighting the acceptability, practicality, and usefulness of the methods used to assess the influence of various organizational and management factors including culture, communication, decision-making, standardization, and oversight. 6 refs., 3 figs., 1 tab

Many veterinary curricula use seminars, interactive educational group formats in which some 25 students discuss questions and issues relating to course themes. To get indications on how to optimize the seminar learning process for students, we aimed to investigate relationships between factors that seem to be important for the seminar learning process, and to determine how these seminar factors account for differences in students' achievement scores. A 57-item seminar evaluation (USEME) questionnaire was administered to students right after they attended a seminar. In total, 80 seminars distributed over years 1, 2, and 3 of an undergraduate veterinary medicine curriculum were sampled and 988 questionnaires were handed in. Principal factor analysis (PFA) was conducted on 410 questionnaires to examine which items could be grouped together as indicators of the same factor, and to determine correlations between the derived factors. Multilevel regression analysis was performed to explore the effects of these seminar factors and students' prior achievement scores on students' achievement scores. Within the questionnaire, four factors were identified that influence the seminar learning process: teacher performance, seminar content, student preparation, and opportunities for interaction within seminars. Strong correlations were found between teacher performance, seminar content, and group interaction. Prior achievement scores and, to a much lesser extent, the seminar factor group interaction appeared to account for differences in students' achievement scores. The factors resulting from the present study and their relation to the method of assessment should be examined further, for example, in an experimental setup.

Hospital care mostly involves complex processes that are continuously adjusted to match individual client needs. As most patients cannot evaluate the technology used, they focus on personal interactions with care providers when making judgements about the care received. Nurses are the care team members that primarily provide ongoing care. This study aims to further understand factors that influence the way nursing staff relate to their patients. A model is presented of the contextual and self-perceptual factors that influence the level of customer/client orientation of nursing services in an Australian hospital setting along with details of a quantitative study. Nurses completed an anonymous questionnaire, which was then mailed directly to the researchers. Analysis of the data included factor analysis, regression and path analysis. The results show that contextual elements such as management commitment to service quality and self-perceptual factors such as role stress impact on the nurses' client service orientation. However, the variables being studied commonly have both direct and indirect effects with feelings about commitment to the organization having a notable mediating influence. The scales adapted from use in other industries are able to measure the perceptual and outcome variables in a health institutional setting. The managerial implications are that both a comprehensive programme of organizational culture and individual staff member development is needed if an enhanced customer orientation and the consequent improvement in client satisfaction with nursing care is to occur.

Apart from the risk of developing glaucoma there is also the risk that it is not detected and irreversible loss of vision ensues. Some studies of methods of glaucoma diagnosis have examined the results of instrument-based examinations with great if not complete reliance on objective findings in arriving at a diagnosis. The very valuable advances in glaucoma detection instrument technologies, and apparent increasing dependence on them, may have led to reduced consideration of information available from a patient history in those studies. Dependence on objective evidence of glaucomatous pathology may reduce the possibility of detecting glaucoma suspects or patients at risk for becoming glaucoma suspects. A valid positive family history of glaucoma is very valuable information. However, negative family histories can often be unreliable due to large numbers of glaucoma cases being undiagnosed. No evidence of family history is appropriate rather than no family history. In addition the unreliability of a negative family history is increased when patients with glaucoma fail to inform their family members. A finding of no family history can only be stated as no known family history. In examining the potential diagnostic contribution from a patient history, this review considers, age, frailty, race, type and degree of refractive error, systemic hyper- and hypotension, vasospasm, migraine, pigmentary dispersion syndrome, pseudoexfoliation syndrome, obstructive sleep apnea syndrome, diabetes, medication interactions and side effects, the degree of exposure to intraocular and intracranial pressure elevations and fluctuations, smoking, and symptoms in addition to genetics and family history of the disease.

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.

Although stomas are necessary for disease treatment, they unavoidably affect patients' lives from physical, psychological, social, spiritual and familial perspectives and contribute to feelings of embarrassment and shame. This study explored the current status and factors influencing stigma among Chinese patients with stoma. A total of 209 patients with stoma at the stoma clinic of a tertiary cancer centre in Guangzhou, China, were recruited and investigated using the Social Impact Scale, the Coping Self-Efficacy Scale, the State Self-Esteem Scale, and a demographic questionnaire. Multivariate linear regression was used to identify the factors influencing stigma. The mean Social Impact Scale score was 69.65±13.18, which represents a moderate effect; specifically, 44% of the patients experienced high levels of stigma. Stoma patients with the following characteristics had high levels of stigma: young, low coping self-efficacy, low stoma acceptance by one's spouse or other family members, poor perceived body image, stool leakage, no experience of participating in activities with other stoma patients. Medical staff members should pay more attention to stigma in stoma patients. Coping self-efficacy, family members' acceptance of the stoma and participation in activities with other stoma patients are influencing factors that protect these patients against stigma, whereas body image loss and stool leakage place them at higher risk for stigma. Interventions aimed at improving protective factors and decreasing risk factors should be considered to reduce the level of stigma in patients with stoma. This article is protected by copyright.

Objectives Data on the incidence of symptomatic osteoarthritis (OA) are scarce. We estimated incidence of clinical hip, knee and hand osteoarthritis, and studied the effect of prevalent OA on joint-specific incident OA. Methods SIDIAP contains primary care records for >5 million people from Catalonia (Spain). Participants aged ≥40 years with an incident diagnosis of knee, hip or hand OA between 2006 and 2010 were identified using ICD-10 codes. Incidence rates and female-to-male Rate Ratios (RR) for each joint site were calculated. Age, gender and body mass index-adjusted Hazard Ratios (HR) for future joint-specific OA according to prevalent OA at other sites were estimated using Cox regression. Results 3,266,826 participants were studied for a median of 4.45 years. Knee and hip OA rates increased continuously with age, and female-to-male RRs were highest at age 70-75 years. In contrast, female hand OA risk peaked at age 60-64 years, and corresponding female-to-male RR was highest at age 50-55. Adjusted HR for prevalent knee OA on risk of hip OA was 1.35 (99%CI 1.28-1.43); prevalent hip OA on incident knee OA 1.15 (1.08-1.23). Prevalent hand OA predicted both incident knee and hip OA: HR 1.20 (1.14-1.26) and 1.23 (1.13-1.34) respectively. Conclusions The effect of age is greatest in the elderly for knee and hip OA, but around the menopause for hand OA. OA clusters within individuals, with higher risk of incident knee and hip disease from prevalent lower limb and hand OA. PMID:23744977

The long-term probability of developing atrial fibrillation (AF) considering genetic predisposition and clinical risk factor burden is unknown. We estimated the lifetime risk of AF in individuals from the community-based Framingham Heart Study. Polygenic risk for AF was derived using a score of ≈1000 AF-associated single-nucleotide polymorphisms. Clinical risk factor burden was calculated for each individual using a validated risk score for incident AF comprised of height, weight, systolic and diastolic blood pressure, current smoking status, antihypertensive medication use, diabetes mellitus, history of myocardial infarction, and history of heart failure. We estimated the lifetime risk of AF within tertiles of polygenic and clinical risk. Among 4606 participants without AF at 55 years of age, 580 developed incident AF (median follow-up, 9.4 years; 25th-75th percentile, 4.4-14.3 years). The lifetime risk of AF >55 years of age was 37.1% and was substantially influenced by both polygenic and clinical risk factor burden. Among individuals free of AF at 55 years of age, those in low-polygenic and clinical risk tertiles had a lifetime risk of AF of 22.3% (95% confidence interval, 15.4-9.1), whereas those in high-risk tertiles had a risk of 48.2% (95% confidence interval, 41.3-55.1). A lower clinical risk factor burden was associated with later AF onset after adjusting for genetic predisposition ( P <0.001). In our community-based cohort, the lifetime risk of AF was 37%. Estimation of polygenic AF risk is feasible and together with clinical risk factor burden explains a substantial gradient in long-term AF risk. © 2018 American Heart Association, Inc.

Type 2 diabetes is a chronic disease that is increasing in prevalence globally. Cardiovascular disease is a major cause of mortality and morbidity in diabetes, and lifestyle and clinical risk factors do not fully account for the link between the conditions. This article provides an overview of the evidence concerning the role of psychosocial stress factors in diabetes risk, as well as in cardiovascular complications in people with existing diabetes. Several types of psychosocial factors are discussed including depression, other types of emotional distress, exposure to stressful conditions, and personality traits. The potential behavioral and biological pathways linking psychosocial factors to diabetes are presented and implications for patient care are highlighted.

Full Text Available Background and Objectives : Inequity in health is a universal term which is used for showing current differences, variations and inequalities of people in accessing to health services. The current study aimed to assess the factors influencing health inequalities to present the results to the researchers and health care professionals. Material and Methods : In this review, several databases including PubMed, Proquest, Scopus, Google Scholar search engine, SID and IranDoc were searched within 2000-2014 period. We found 746 articles and refined them step by step according to the aim of the study by reviewing the titles, abstracts and full texts. Finally, 16 articles were selected for further study Results: In the present study, identified determinants in health inequalities were as follows: 1- Economic and income factors 2- Political factors, social and public policy 3- Cultural and social values 4- social and demographic factors 5- Behavioral, psychological and biological factors. Although, other factors like governmental, international, social cohesion, incidents and even the health system itself were involved in health inequalities, but the listed determinants were among the most important determinants in health inequalities in the conducted studies. Conclusion : Given the importance of people's health and inequalities in health, the approach should focus on reducing the inequalities in all policies and development programs and the role of these factors should be taken into consideration by managers and policy-makers

Egg consumption is often discouraged due to cholesterol content; however, recent studies have not demonstrated a clear adverse influence of eggs on blood lipids. Furthermore, exercise training promotes improved lipids and blood pressure. The purpose of the study was to examine the effect of eating an isoenergetic (400 kcal) egg-based (including two eggs per day) versus bagel-based breakfasts, daily, combined with resistance training three times per week, prior to breakfast, on plasma lipids, glucose, insulin, insulin sensitivity and blood pressure in untrained individuals. Twenty-five healthy adult men and women (18-35 years of age) participated in the twelve week study following random assignment to study groups. Lipids and blood pressure were examined at baseline and after 6 and 12 weeks. Plasma triglycerides (TG) decreased significantly in the egg- based breakfast (EBB) group from baseline to six weeks (p = 0.011) and from six to twelve weeks (p = 0.045). A significant (p = 0.033) decrease in insulin sensitivity was observed in the bagel-based breakfast (BBB) group from zero to six weeks. No significant effects on systolic blood pressure, diastolic blood pressure, total cholesterol, high density lipoprotein- cholesterol or low density lipoprotein cholesterol were detected. Overall, daily breakfasts including two eggs for twelve weeks did not adversely affect lipids during a resistance training program and promoted improvements in plasma TG.

Interest and applications to surgery have steadily decreased over recent years in the United States. The goal of this review is to collect the current literature regarding US medical students' experience in surgery and factors influencing their intention to pursue surgery as a career. We hypothesize that multiple factors influence US medical students' career choice in surgery. Six electronic databases (PubMed, SCOPUS, Web of Science, Education Resources Information Center, Embase, and PsycINFO) were searched. The inclusion criteria were studies published after the new century related to factors influencing surgical career choice among US medical students. Factors influencing US medical student surgical career decision-making were recorded. A quality index score was given to each article selected to minimize risk of bias. We identified 38 relevant articles of more than 1000 nonduplicated titles. The factors influencing medical student decision for a surgical career were categorized into five domains: mentorship and role model (n = 12), experience (clerkship n = 9, stereotype n = 4), timing of exposure (n = 9), personal (lifestyle n = 8, gender n = 6, finance n = 3), and others (n = 2). This comprehensive systemic review identifies mentorship, experience in surgery, stereotypes, timing of exposure, and personal factors to be major determinants in medical students' decisions to pursue surgery. These represent areas that can be improved to attract applicants to general surgery residencies. Surgical faculty and residents can have a positive influence on medical students' decisions to pursue surgery as a career. Early introduction to the field of surgery, as well as recruitment strategies during the preclinical and clinical years of medical school can increase students' interest in a surgical career.

Previous research on online consumer behavior has mostly been confined to the perceived risk which is used to explain those barriers for purchasing online. However, perceived benefit is another important factor which influences consumers’ decision when shopping online. As a result, an integrated consumer online shopping decision-making model is developed which contains three elements—Consumer, Product, and Web Site. This model proposed relative factors which influence the consumers’ intention during the online shopping progress, and divided them into two different dimensions—mentally level and material level. We tested those factors with surveys, from both online volunteers and offline paper surveys with more than 200 samples. With the help of SEM, the experimental results show that the proposed model and method can be used to analyze consumer’s online shopping decision-making process effectively.

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. Published by Oxford University Press on behalf of the Johns Hopkins Bloomberg School of Public Health 2015.

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

This study was conducted to identify the factors that influence nurses' organizational citizenship behavior. A cross-sectional design was used, with a convenience sample of 547 nurses from four university hospitals in Seoul and Gyeonggi province. The data were collected through a questionnaire survey done from September 22 to October 10, 2008. The tools used for this study were scales on organizational citizenship behavior (14 items), self-leadership (14 items), empowerment (10 items), organizational commitment (7 items), job satisfaction (8 items) and transformational.transactional leadership (14 items). Cronbach's alpha and factor analysis were examined to test reliability and construct validity of the scale. The data collected were processed using SPSS Window 15.0 Program for actual numbers and percentages, differences in the dependent variable according to general characteristics, and means, standard deviations, correlation coefficients and multiple regression analysis. The factors influencing nurses' organizational citizenship behavior were identified as self-leadership(beta=.247), empowerment (beta=.233), job satisfaction (beta=.209), organizational commitment (beta=.158), and transactional leadership (beta=.142). Five factors explained 42.0% of nurses' organizational citizenship behavior. The results of this study can be used to develop further management strategies for enhancement of nurses' organizational citizenship behavior.

Women veterans are three to four times more likely than non-veteran women to become homeless. However, their risk factors for homelessness have not been defined. Case-control study of non-institutionalized homeless women veterans (n533) and age-matched housed women veterans (n=165). Health, health care, and factors associated with homelessness were assessed using multiple logistic regression with a Monte Carlo algorithm to estimate exact standard errors of the model coefficients and p-values. Characteristics associated with homelessness were sexual assault during military service, being unemployed, being disabled, having worse overall health, and screening positive for an anxiety disorder or post-traumatic stress disorder. Protective factors were being a college graduate or married. Efforts to assess housed women veterans' risk factors for homelessness should be integrated into clinical care programs within and outside the Veterans Administration. Programs that work to ameliorate risk factors may prevent these women's living situations from deteriorating over time.

Workplace violence has attracted increasing public attention over the past few decades in China. This study was conducted to evaluate the frequency of workplace violence in healthcare settings by various job titles and hospital departments, and to explore the related risk factors among Chinese medical professionals. A total of 2,464 medical professionals in 12 hospitals of two provinces were surveyed by using a stratified cluster sampling method. The Chinese version of the Workplace Violence Scale was used to measure the frequencies of workplace violence, classified as physical assault, emotional abuse, threat of assault, verbal sexual harassment and sexual assault experienced by the subjects over the previous 12 months. A structured questionnaire was administered to collect information on potentially influencing factors for workplace violence. Multivariate analysis was applied to determine the risk factors for workplace violence. About 50% of study subjects reported at least one type of workplace violence. The rates of experiencing two episodes or more of physical assault, emotional abuse, threat of assault, verbal sexual harassment, and sexual assault were 11%, 26%, 12%, 3%, and 1%, respectively. Identified risk factors for workplace violence included working in the departments of psychiatry, emergency, pediatrics and surgery, male gender, divorce/widowed status, long working hours (≥10 hr/day), and night shift. The study suggested that workplace violence occurs commonly in Chinese healthcare settings. Effective intervention strategies targeting workplace violence should be formulated in terms of major risk factors. Copyright © 2012 Wiley Periodicals, Inc.

Full Text Available In this paper we estimate the impact of different factors on creditability of agricultural farms. According to the literature the collateral (tangible assets, the farm size, productivity, and subsidies should have significant effects on farm loans. We use data from the Hungarian Farm Accountancy Data Network to test our two hypotheses and theoretical assumptions for the period 2001-2010. Because of using panel data, we do our estimations using fixed effects econometrics model to test our assumptions. The results indicate that the chosen factors have significant influence on total liabilities and short- and long-term loans as well. With specially interest of subsidies the growing level of supports decrease the need of other financial tools. At output factors (inclusive farm size have significant and positive effect, same as collateral (tangible assets.

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.

Full Text Available BACKGROUND: Few studies have investigated predictors of discordance between liver biopsy (LB and liver stiffness measurement (LSM using FibroScan®. We assessed predictors of discordance between LB and LSM in chronic hepatitis B (CHB and investigated the effects of necroinflammatory activity. METHODS: In total, 150 patients (107 men, 43 women were prospectively enrolled. Only LSM with ≥ 10 valid measurements was considered reliable. Liver fibrosis was evaluated using the Laennec system. LB specimens <15 mm in length were considered ineligible. Reference cutoff LSM values to determine discordance were calculated from our cohort (6.0 kPa for ≥ F2, 7.5 kPa for ≥ F3, and 9.4 kPa for F4. RESULTS: A discordance, defined as a discordance of at least two stages between LB and LSM, was identified in 21 (14.0% patients. In multivariate analyses, fibrosis stages F3-4 and F4 showed independent negative associations with discordance (P = 0.002; hazard ratio [HR], 0.073; 95% confidence interval [CI], 0.014-0.390 for F3-4 and P = 0.014; HR, 0.067; 95% CI, 0.008-0.574 for F4. LSM values were not significantly different between maximal activity grades 1-2 and 3-4 in F1 and F2 fibrosis stages, whereas LSM values were significantly higher in maximal activity grade 3-4 than 1-2 in F3 and F4 fibrosis stage (median 8.6 vs. 11.3 kPa in F3, P = 0.049; median 11.9 vs. 19.2 kPa in F4, P = 0.009. CONCLUSION: Advanced fibrosis stage (F3-4 or cirrhosis (F4 showed a negative correlation with discordance between LB and LSM in patients with CHB, and maximal activity grade 3-4 significantly influenced LSM values in F3 and F4.

This review outlines risk factors of post-laser in situ keratomileusis (LASIK) ectasia that can be detected preoperatively and presents a new metric to be considered in the detection of ectasia risk. Relevant factors in refractive surgery screening include the analysis of intrinsic biomechanical properties (information obtained from corneal topography/tomography and patient’s age), as well as the analysis of alterable biomechanical properties (information obtained from the amount of tissue altered by surgery and the remaining load-bearing tissue). Corneal topography patterns of placido disk seem to play a pivotal role as a surrogate of corneal strength, and abnormal corneal topography remains to be the most important identifiable risk factor for ectasia. Information derived from tomography, such as pachymetric and epithelial maps as well as computational strategies, to help in the detection of keratoconus is additional and relevant. High percentage of tissue altered (PTA) is the most robust risk factor for ectasia after LASIK in patients with normal preoperative corneal topography. Compared to specific residual stromal bed (RSB) or central corneal thickness values, percentage of tissue altered likely provides a more individualized measure of biomechanical alteration because it considers the relationship between thickness, tissue altered through ablation and flap creation, and ultimate RSB thickness. Other recognized risk factors include low RSB, thin cornea, and high myopia. Age is also a very important risk factor and still remains as one of the most overlooked ones. A comprehensive screening approach with the Ectasia Risk Score System, which evaluates multiple risk factors simultaneously, is also a helpful tool in the screening strategy. PMID:27143849
About a century after Koch's discovery of the TB bacilli the tuberculosis epidemic which had appeared to be under control was again recognized as a major global health threat. The decline in the epidemic in this century had been largely through the improved living standards and, eventually, the availability and use of effective antibiotics. While tuberculosis gradually disappeared from the health agenda in the western world it remained a big killer throughout the century and in 1992 an estimated 2.7 million TB deaths occurred; 30 million will die from TB during the 1990s if current trends are not reversed. The annual number of new cases will increase from 7.5 million estimated in 1990 to more than 10 million in the year 2000. The main factors for this increase are demographic forces, population movements, the HIV epidemic and increasing drug resistance. The impact of the HIV epidemic is already felt in many sub-Saharan African countries and now threatens Asia where almost two-thirds of the world's TB infected population live and where HIV is spreading. Tuberculosis has also reemerged as a major public health problem in industrialized countries due to international migration, the breakdown of health services, including TB services etc. The control of the epidemic can only be through a concerted action to reinstate TB as priority among health concerns, reflected in national and international resources. A coalition of public and private supporters must be mobilized to support the effort to fight the disease. Governments, non-governmental organizations, the business community, refugee organizations, medical institutions, and other UN agencies are invited to join with WHO in this effort.
Full Text Available The aim of the systematic ensuring of knowledge continuity is the continuity of an organisation’s development, the quality of managerial positions and the continuity of decision-making. By ensuring knowledge continuity, organisations may gain a performance-enhancing factor. The objective of the article is to identify the level of impact of decisive internal factors determining knowledge continuity ensuring and contributing to the efficiency of the organisations. Knowledge continuity ensuring as an internal force, however, can together with the right employees, help adapt more quickly to external conditions that organisations can hardly control. Monitoring and ensuring knowledge continuity can contribute to a higher quality of processes in general, in particular processes exploiting knowledge, and thus help improve the level of management. The first part of the article presents theoretical views on the aspects of knowledge continuity ensuring in organisations while the second part analyses the findings of the surveys carried out among managers in organisations in the Czech Republic. Based on the summary of the outcomes obtained it is possible to say that internal factors influence knowledge continuity ensuring in organisations, however, the level of impact of individual factors is determined by their size. The findings regarding the impact of each of the factors show that the most significant barriers to knowledge continuity ensuring are those associated with the human factor.

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

This manuscript overviews the pertinent research on internal color of uncured cooked meats, biochemical processes involved in meat cookery, and fundamental mechanisms governing myoglobin thermal stability. Heat-induced denaturation of myoglobin, responsible for the characteristic dull-brown color of cooked meats, is influenced by a multitude of endogenous (i.e., pH, muscle source, species, redox state) and exogenous (i.e., packaging, ingredients, storage) factors. The interactions between these factors critically influence the internal cooked color and can confuse the consumers, who often perceive cooked color to be a reliable indicator for doneness and safety. While certain phenomena in cooked meat color are cosmetic in nature, others can mislead consumers and result in foodborne illnesses. Research in meat color suggests that processing technologies and cooking practices in industry as well as households influence the internal cooked color. Additionally, the guidelines of many international public health and regulatory authorities recommend using meat thermometers to determine safe cooking endpoint temperature and to ensure product safety.

To assess the efficacy of percutaneous transluminal angioplasty (PTA) in patients with infrapopliteal arterial disease, and to determine the influencing factor for prognosis. A total of 55 patients (60 limbs) with infrapopliteal arterial stenosis or occlusion underwent PTA. Atherosclerotic risk factors, clinical symptoms, TransAtlantic Inter-Society Consensus (TASC) classification, and vascular wall calcification were evaluated before PTA. The number of patent infrapopliteal arteries was estimated, and the outcome was evaluated by symptom relief and limb salvage. Technical success was achieved in 53/60 limbs (88.3%) and 81/93 arteries (87.1%), TASC classification (p = 0.038) and vascular calcification (p = 0.002) influenced on technical failure. During follow-up, 26 of 55 limbs (47%) achieved symptom relief and 42/55 limbs (76%) underwent limb salvage. Non-diabetic patients (9/12, 75%) were superior to diabetic patients (17/43, 40%) in terms of symptom relief (p = 0.024). TASC classification and vascular wall calcification influenced on symptom relief and limb salvage. The number of patent infrapopliteal arteries after PTA influenced symptom relief (p < 0.001) and limb amputation (p = 0.003). PTA in patients with chronic critical limb ischemia is worthwhile as a primary treatment. The influence factors should be considered before PTA, and PTA should be performed in as many involved arteries as possible.

Analysis of the factors which have an influence on the reduction of residuary strengths due to alkaline solution in the interstitial mortars of concretes with aluminous cement Assessment of the risk limits in the case of roof beams
Goma Ginesta, Ferrán
Full Text Available The scarce references which exist in the bibliography on this subject and their vagueness on the factors which have an influence on the reduction of the strength of aluminous cement concrete due to the effect of alkalinity, have not yet allowed the limits to be clearly seen which could give rise to a situation of risk in the structural elements due to this cause.
A study is presented which endeavors to measure the quantitative influence of different parameters of the same or of a similar conditions to those presented in the usual types of concrete in existing beams with aluminous cement characteristic of our market.
The parameters tested were: the influence of the concentration of free ions OH-, the class of alkaline ion, the temperature, the time, the presence or absence of CO2, the degree of conversion, the physical parameters, porosities, densities, etc., and the phases existing were determined by XRD, DTA and TG before and after the alkaline action.
From the results obtained in numerous series of Rilem mortars and micro-mortars, it is possible to see the possibility of establishing the setting of parameters which define areas without risk.

Full Text Available The article presents current data about the risk factors of main lower limb fractures (LLFs of different localization (femur, tibia and foot. It has been shown that the most studies examine epidemiology and risk factors for hip fractures, but information about the risk factors for other LLFs is insufficient and controversial. It has been demonstrated that in addition to factors of age and sex, the road traffic accidents, sports, inadequate physical activity, injuries, falls and previous fractures play the important role in the development of LLFs. Also some diseases (systemic osteoporosis, large joints osteoarthritis, rheumatoid arthritis, dementia, epilepsy, alcoholism, parkinsonism, cancer, obesity and cataract can influence the LLFs risk. Administration of some drugs, in particular, hypnotic and sedative, as well as antidepressants, antipsychotic drugs and glucocorticoids, is the additional risk factor for LLFs. Almost all types of fractures in women are associated with low bone mineral density, which is more defined at femoral neck than at spine or peripheral skeleton, but part of fractures associated with osteoporosis is small and ranges from 10 to 44 %. The assessment of risk factors should necessarily be carried out in routine clinical practice in patients with LLFs, since it affects not only their incidence, but also the prognosis of treatment of these patients.

BACKGROUND: Persistent postherniotomy pain (PPP) affects everyday activities in 5-10% of patients. Identification of predisposing factors may help to identify the risk groups and guide anesthetic or surgical procedures in reducing risk for PPP. METHODS: A prospective study was conducted in 464...... patients undergoing open or laparoscopic transabdominal preperitoneal elective groin hernia repair. Primary outcome was identification of risk factors for substantial pain-related functional impairment at 6 months postoperatively assessed by the validated Activity Assessment Scale (AAS). Data on potential...... risk factors for PPP were collected preoperatively (pain from the groin hernia, preoperative AAS score, pain from other body regions, and psychometric assessment). Pain scores were collected on days 7 and 30 postoperatively. Sensory functions including pain response to tonic heat stimulation were...

According to the model of substance abuse of Conrod, Pihl, Stewart, and Dongier (2000), four personality factors (i.e., anxiety sensitivity [AS], introversion/hopelessness [I/H], sensation seeking [SS], and impulsivity [IMP]) are associated with elevated risk for substance use/misuse, with each personality factor being related to preference for particular drugs of abuse (e.g., AS with anxiolytics). However, cannabis use has not been consistently linked to any one of these personality factors. This may be due to the heterogeneity in cannabis use motives. The present study explored the association between these four personality risk factors and different cannabis use motives. Cannabis users completed an interview about their motives for cannabis use as well as the self-report Substance Use Risk Profile Scale (SURPS; Woicik, Conrod, Stewart, & Pihl, 2009), which measures the four personality risk factors. Results showed that AS was associated with conformity motives and I/H was associated with coping motives for cannabis use. SS was positively associated with expansion motives and IMP was associated with drug availability motives. Thus, personality risk factors in the model of Conrod et al. (2000) are associated with distinct cannabis use motives in a pattern consistent with theory. Copyright © 2013 Elsevier Ltd. All rights reserved.

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.

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.

The diversity of experimental methods and terminology employed by investigators to measure the effects of high temperatures on individual organisms, plus the often overlooked complexities of the holocoenotic environment, has often led to disconcerting conclusions. A plea is made for standardization of testing methods and for a wider appreciation of factors that may alter thermal tolerances. The influence of elevated temperature is grouped into three categories, lethal effects, controlling effects, and directive effects, all of which should be considered in assessing the impact of thermal effluent on organisms. In addition, the terminology (acclimation, acclimatization, adaptation, habituation, lethal temperature, critical thermal maximum, etc.) needs standardized definitions. The important factors influencing thermal effects on organisms include photoperiod, seasonal and daily cycles, geographic variation, diet, sex, breeding condition, age, life-cycle stage, salinity, chemicals, body water content and partitioning, oxygen supply, pH, innate and learned behavior, history of thermal exposure, sublethal exposure to limiting factors, and experimental methods. Examples of most of these are given to illustrate the role of temperature in the holocoenotic environmental complex of individual organisms
Full Text Available The aim of the paper is to present an overview of recent findings on the environmental and behavioral factors influencing the development of atherosclerosis. The authors primarily concentrated on deliberations of possibile main causes of the damage of the endothelium. At the same time the following pathogenic mechanisms as cellular dysfunction, inflammation and coagulation disorders have been enumerated. The links between the state of the vascular endothelium and life style have been emphasized. It is also important to note that the primary causes of the endothelial damage should be traced as originally suggested many years ago viewing such factors as anger, hostility, aggression, impulsiveness and depression but with a new approach. The authors supplement the comments, on the environmental factors influencing the development of atherosclerosis, with basic data on family predisposition to the development of this disease. They highlight that current genetic research have not determined genes responsible for atheroscelosis. According to the authors the considerations and conclusions presented in this overview are important for the educational purposes related to the most frequent disease process resulting in many diseases in medical disciplines.

To review the best current evidence regarding the effects of exercise on modifiable risk factors for adverse physiologic outcomes of cancer and its treatment. Clinical practice guidelines, systematic reviews, meta-analyses, and single studies. There is mounting evidence that exercise improves fatigue, physical functioning, and cardio-respiratory fitness. Preliminary evidence suggests that exercise also contributes to improvements in body weight and composition, metabolic risk factors, and immune function. It may also influence disease-free and overall survival in selected populations. Exercise appears to be a safe and well-tolerated intervention that may minimize or prevent adverse physiologic outcomes of cancer and cancer treatment.

This article presents the main studies that describe the importance of investigating the risk factors for cardiovascular diseases in childhood and their associations. Significant rates of hypertension, obesity, dyslipidemia, and sedentariness occur in children and adolescents. Blood pressure needs to be measured in childhood. An increase in arterial blood pressure in young people predicts hypertension in adulthood. The death rate from cardiovascular disease is lowest in children with lower cholesterol levels and in individuals who exercise regularly. In addition, there is a high prevalence of sedentariness in children and adolescents.Conclusions: Studies involving the analysis of cardiovascular risk factors should always report the prevalence of these factors and their correlations during childhood because these factors are indispensable for identifying an at-risk population. The identification of risk factors in asymptomatic children could contribute to a decrease in cardiovascular disease, preventing such diseases as hypertension, obesity, and dyslipidemia from becoming the epidemics of this century.Keywords: cardiovascular risk, children, hypertension, obesity

The study was done to identify turnover intention in new nurses according to characteristics of the nurses and other factors affecting turnover and to provide data to set up a strategy to reduce the turnover. Data were collected from 1,077 new nurses who had less than 12 months employment experience and worked in one of 188 hospitals. Eight research instruments were used. Data analysis was done using SPSS WIN 15.0 program. Several factors influence new nurse turnover intention. The average score for turnover intention was 2.12. The scores for subscales were self efficacy, 3.76, nursing performance, 3.90, job satisfaction, 2.09, organization commitment, 1.28, stress, 1.32, burnout, 2.82 and nursing organizational culture, 3.29. Turnover intention was related to self efficacy, nursing performance, job satisfaction, organization commitment, stress, burnout, nursing organizational culture, duration of in-class training, duration of on the job training, number of hospital beds, length of employment and duration of employment in current workplace. The predicting factors for turnover intention were burnout, stress, duration of employment in the current workplace, self efficacy and nursing performance. Those factors explained 51.6% of turnover intention. New nurse turnover intention can be reduced by mitigating the factors affecting this intention.

Vulvovaginal candidiasis (VVC) is an infection caused by Candida species that affects millions of women every year. Although Candida albicans is the main cause of VVC, the identification of non-Candida albicans Candida (NCAC) species, especially Candida glabrata, as the cause of this infection, appears to be increasing. The development of VVC is usually attributed to the disturbance of the balance between Candida vaginal colonization and host environment by physiological or nonphysiological changes. Several host-related and behavioral risk factors have been proposed as predisposing factors for VVC. Host-related factors include pregnancy, hormone replacement, uncontrolled diabetes, immunosuppression, antibiotics, glucocorticoids use and genetic predispositions. Behavioral risk factors include use of oral contraceptives, intrauterine device, spermicides and condoms and some habits of hygiene, clothing and sexual practices. Despite a growing list of recognized risk factors, much remains to be elucidated as the role of host versus microorganisms, in inducing VVC and its recurrence. Thus, this review provides information about the current state of knowledge on the risk factors that predispose to VVC, also including a revision of the epidemiology and microbiology of VVC, as well as of Candida virulence factors associated with vaginal pathogenicity.

Anticoagulants are drugs capable to retard or even cancell the process of blood coagulation. They are many factors who influences the intensity and duration of oral anticoagulant acitivity, such as drugs, body constitution, physical agents, diseases, etc. The oral anticoagulants interacts with other drugs at differents levels: at the gut, at the plasma, modiffing the protein binding or the metabolism of such drugs, at the enzimatic induction or inhibition, or at unknown places with many other drugs. These paper deals with the description of such interactions.

This study sought to examine risk and onset patterns in anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Women with AN (n=71), BN (n=66), BED (n=160) and non-psychiatric controls (n=323) were compared retrospectively on risk factors, symptom onset, and diagnostic migration. Eating disorder groups reported greater risk exposure than non-psychiatric controls. AN and BED differed on premorbid personality/behavioral problems, childhood obesity, and family overeating. Risk factors for BN were shared with AN and BED. Dieting was the most common onset symptom in AN, whereas binge eating was most common in BN and BED. Migration between AN and BED was rare, but more frequent between AN and BN and between BN and BED. AN and BED have distinct risk factors and onset patterns, while BN shares similar risk factors and onset patterns with both AN and BED. Results should inform future classification schemes and prevention programs. Copyright © 2014. Published by Elsevier Ireland Ltd.

Full Text Available Nowadays, the issue of “globalization” is entering to all areas in the world. In addition to products and companies, cities and countries also have the opportunity to see themselves as important actors in international arena. Places define their positions in different fields like business, leisure and recreation, educational opportunities, living, etc. This paper presents an empirical study to introduce city branding as one of the solutions to join globalization process. The method of this research is based on the “descriptive-analytic” and utilize the available literature and experts’ opinions to prioritize the influencing factors of city branding. We use Delphi consensus methods and technique of analytical hierarchy process to evaluate the factors. Finally, the results of the study indicate that security, transportation and mental creativity are the weakest fields and business and shopping facilities are strong fields of city branding in metropolitan of Tehran.

This review evaluates those main risk factors that can affect patients undergoing thyroidectomy, to reach a better pre- and post-operative management of transient and permanent hypoparathyroidism. The transient hypoparathyroidism is a potentially severe complication of thyroidectomy, including a wide range of signs and symptoms that persists for a few weeks. The definitive hypoparathyroidism occurs when a medical treatment is necessary over 12 months. Risk factors that may influence the onset of this condition after thyroidectomy include: pre- and post-operative biochemical factors, such as serum calcium levels, vitamin D blood concentrations and intact PTH. Other involved factors could be summarized as follow: female sex, Graves' or thyroid neoplastic diseases, surgeon's dexterity and surgical technique. The medical treatment includes the administration of calcium, vitamin D and magnesium sometimes. Although biological and biochemical factors could be related to iatrogenic hypoparathyroidism, the surgeon's experience and the used surgical technique still maintain a crucial role in the aetiology of this important complication.

The present study aims to examine risk factors and risk-based and interactive protective factors for violent offending in a group of 437 young Australians. Participants were recruited into the study when they were in Grade 5 (10-11 years) and followed up almost annually until young adulthood (18-19 years). Measures of violent offending, risk and protective factors, and demographics were obtained through a modification of the Communities That Care youth survey. The data collected enabled identification of groups of students at-risk of violent offending according to drug use, low family socioeconomic status, and antisocial behavior. Results showed that there were very few associations between the risk factors and risk-based protective factors measured in this study (e.g., belief in the moral order, religiosity, peer recognition for prosocial involvement, attachment to parents, low commitment to school, and poor academic performance) and later self-reported violent offending. There were no statistically significant interactive protective factors. Further longitudinal analyses with large sample sizes are needed to examine risk factors and risk-based protective factors and interactive protective factors in at-risk groups. The findings support the need for multi-faceted prevention and early intervention approaches that target multiple aspects of youth's lives.

The proper prenatal care for pregnant women is crucial to quickly identify risk factors for birth trauma. To identify risk factors for neonatal birth trauma. Case-control study that included a patient in the case group for every two controls. The following risk factors were identified: cephalopelvic disproportion, macrosomia, use of forceps, precipitated or prolonged labor, malpresentation, and the most common types of birth trauma. We used descriptive statistics and odds ratios. Statistically significant risk factors for birth trauma were: maternal age or = 30 years (OR = 2.5), first pregnancy (OR = 4.0), cephalopelvic disproportion (OR = 8.3), forceps delivery (OR = 9.4), birth weight greater than 3,800 g (OR = 6.6), and non-cephalic presentation (OR = 8.3). Found birth trauma types were: ecchymosis (40.4%), caput succedaneum (25%), erosion (15.4%), clavicle fracture (5.9%), brachial plexus paralysis (4.7%), inter alia. The perinatal outcome of 79 infants with birth trauma were compared to 158 healthy newborns. Risk factors associated with birth injuries were: Maternal (age, pregnancy), newborn (weight), and birth care (presentation, instrumentation and pelvic sufficiency).

Abstract Recurrent lumbar disc herniation (rLDH) is a common complication following primary discectomy. This systematic review aimed to investigate the current evidence on risk factors for rLDH. Cohort or case-control studies addressing risk factors for rLDH were identified by search in Pubmed (Medline), Embase, Web of Science, and Cochrane library from inception to June 2015. Relevant results were pooled to give overall estimates if possible. Heterogeneity among studies was examined and publication bias was also assessed. A total of 17 studies were included in this systematic review. Risk factors that had significant relation with rLDH were smoking (OR 1.99, 95% CI 1.53–2.58), disc protrusion (OR 1.79, 95% CI 1.15–2.79), and diabetes (OR 1.19, 95% CI 1.06–1.32). Gender, BMI, occupational work, level, and side of herniation did not correlate with rLDH significantly. Based on current evidence, smoking, disc protrusion, and diabetes were predictors for rLDH. Patients with these risk factors should be paid more attention for prevention of recurrence after primary surgery. More evidence provided by high-quality observational studies is still needed to further investigate risk factors for rLDH. PMID:26765413

Full Text Available Cognitive impairment, including Alzheimer's disease and other kinds of dementia, is a major health problem in older adults worldwide. Although numerous investigators have attempted to develop effective treatment modalities or drugs, there is no reasonably efficacious strategy for preventing or recovering from cognitive impairment. Therefore, modifiable risk factors for cognitive impairment have received attention, and the growing literature of metabolic risk factors for cognitive impairment has expanded from epidemiology to molecular pathogenesis and therapeutic management. This review focuses on the epidemiological evidence for the association between cognitive impairment and several endocrine risk factors, including insulin resistance, dyslipidemia, thyroid dysfunction, vitamin D deficiency, and subclinical atherosclerosis. Researches suggesting possible mechanisms for this association are reviewed. The research investigating modifiable endocrine risk factors for cognitive impairment provides clues for understanding the pathogenesis of cognitive impairment and developing novel treatment modalities. However, so far, interventional studies investigating the beneficial effect of the "modification" of these "modifiable risk factors" on cognitive impairment have reported variable results. Therefore, well-designed, randomized prospective interventional studies are needed.

To investigate the rate of automation bias - the propensity of people to over rely on automated advice and the factors associated with it. Tested factors were attitudinal - trust and confidence, non-attitudinal - decision support experience and clinical experience, and environmental - task difficulty. The paradigm of simulated decision support advice within a prescribing context was used. The study employed within participant before-after design, whereby 26 UK NHS General Practitioners were shown 20 hypothetical prescribing scenarios with prevalidated correct and incorrect answers - advice was incorrect in 6 scenarios. They were asked to prescribe for each case, followed by being shown simulated advice. Participants were then asked whether they wished to change their prescription, and the post-advice prescription was recorded. Rate of overall decision switching was captured. Automation bias was measured by negative consultations - correct to incorrect prescription switching. Participants changed prescriptions in 22.5% of scenarios. The pre-advice accuracy rate of the clinicians was 50.38%, which improved to 58.27% post-advice. The CDSS improved the decision accuracy in 13.1% of prescribing cases. The rate of automation bias, as measured by decision switches from correct pre-advice, to incorrect post-advice was 5.2% of all cases - a net improvement of 8%. More immediate factors such as trust in the specific CDSS, decision confidence, and task difficulty influenced rate of decision switching. Lower clinical experience was associated with more decision switching. Age, DSS experience and trust in CDSS generally were not significantly associated with decision switching. This study adds to the literature surrounding automation bias in terms of its potential frequency and influencing factors. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

To evaluate the contamination rate and the corresponding spectrum of microbes and to identify donor risk factors for corneal organ culture contaminations. A total of 3306 organ-cultured donor corneas were included in the study. We performed a retrospective database analysis to evaluate donor factors such as gender, age, death-to-explantation interval (DEI), procurement site and cause of death and to determine their influence on donor cornea contaminations. Odds ratios (ORs) were calculated for each factor. The overall contamination rate was 7.8% (n = 259). Younger donor age (OR: 2.2, p = 0.003, chi-squared test), a DEI of more than 24 hr (OR: 1.6, p donor gender did not have an effect on donor cornea contaminations. The most frequently isolated microbes were Enterococci (19%), Staphylococci (10.8%) and Candida (37.4%). This study helps to estimate the contamination risk of a cultured cornea based on specific donor factors. However, donors with risk factors should not be generally excluded from cornea donation. Further studies including antibiograms might clarify whether a change in the antibiotic composition of the culture medium would be useful to deal with the increasing number of multi-resistant microbes. © 2017 Acta Ophthalmologica Scandinavica Foundation.

Full Text Available Few studies address the ecology of herbs of Cerrado grasslands, which are ecosystems where the long dry season, high temperatures, insolation, fire and invasive grasses greatly influencing germination and the establishment of plants. We assessed germination of 13 species of Poaceae from Cerrado grasslands under nursery conditions or in germination chambers, the latter with i recently collected seeds and seeds after six months storage, ii under constant and alternating temperatures, and iii in the presence and absence of light. Germinability, mean germination time (MGT and required light were quantified to elucidate factors involved in successful germination. Germinability was low for most grasses, probably because of low seed viability. For most species, germinability and MGT were not altered by seed storage. Germination percentages were higher at alternating temperatures and in the presence of light, factors that are more similar to natural environmental situations compared with constant temperature or the absence of light. Our findings indicate that alternating temperatures and light incidence are key factors for germination of species of Poaceae. The maintenance of these environmental factors, which are crucial for the conservation of Cerrado grasslands, depends on appropriate management interventions, such as fire management and the control of biological invasion.

To examine factors affecting the job satisfaction of registered nurses (RNs). A growing recognition of job dissatisfaction among RNs in South Carolina hospitals has contributed to current problems with recruitment and retention. If administrators identify factors influencing RNs' job satisfaction in hospitals and implement strategies to address these factors, RN turnover rates will decrease and recruiting and retention rates will increase. A cross-sectional study of secondary data was designed to identify the individual, work, and geographic factors that impact nursing job satisfaction at the state level. A 27-question self-administered survey was sent to 17,500 RNs in South Carolina with postage-paid envelopes for their responses. Surveys from 3472 nurses were completed anonymously. Univariate statistics were used to describe the study sample. One-way and multivariable Analysis of Variance were used to determine which variables contributed the most to job satisfaction. For about two thirds of the RNs, job satisfaction remained the same or had lessened over the past 2 years. In addition, statistically significant differences were found between job satisfaction and years of service, job position, hospital retirement plan, and geographic area. The findings have implications for nurse managers and hospital administrators for planning and implementing effective health policies that will meet the unique needs of their staffs and organizations. Such research is particularly relevant in this difficult time of nursing shortages throughout the healthcare industry.

The aim of this experimental study was to identify relevant surgical parameters influencing the mesiodistal angular deviation of dental implants. Pilot drillings of 2 mm diameter were performed in bovine ribs with a parallelometer. The subsequent preparation of the implant socket was performed freehand. Utilizing six different implant systems, at least 80 drillings per system of different diameters were performed. The pilot drillings were marked with 2 mm steel pins and cephalometric radiographs were taken. The mesiodistal angle between the longitudinal implant axis and the marked pilot drillings was measured and evaluated by a blinded investigator. To evaluate the influence of the surgeons' experience, their drillings were compared with those of a group of unexperienced surgeons. Additionally, the influence of drilling speed and size of bur steps on drilling accuracy were evaluated. The difference between the lowest value of 0.91 degrees of mesiodistal angular deviation found for 3i implants and the highest of 1.36 degrees for Ankylos implants was of low statistical significance (P=0.065). Drillings of experienced surgeons showed less deviation compared with those of a beginners group (P<0.0001). Higher deviations were measured when a bur size was skipped. Drillings performed at high speed showed significantly higher deviations than those with fewer rewinds per minute. In order to achieve precise implant angulation, all bur diameters available should be used. Utilizing low drilling speeds results in less mesiodistal deviation. The surgeon's experience seems to be the most relevant factor in precise implant placement.

To investigate risk factors for relaparotomy after cesarean section (CS). A retrospective case-control study comparing all CS that were complicated with relaparotomy to cesarean deliveries without this complication. Relaparotomy complicated 0.23% (n=80) of CS during the study period (n=34,389). Independent risk factors for relaparotomy following CS from a multivariable logistic regression model were post partum hemorrhage, cervical tears, placenta previa, uterine rupture, placental abruption, severe preeclampsia and previous CS. Most women (51.2%) underwent relaparotomy during the first 24 h after CS. The leading causes for relaparotomy was bleeding (70%) and burst abdomen (8.8%). Hysterectomy was performed in 31.3% of the patients. Risk factors for relaparotomy after CS are previous CS, severe preeclampsia, placenta previa, uterine rupture, placental abruption, cervical tear and PPH. Experienced obstetricians should be involved in such cases and the possibility for complications including relaparotomy should be emphasized.

Perceptions of disease risk play an important role in motivating people to adopt healthy behaviors. However, little is known about psychosocial factors that influence women's perceived risk for developing disease. The present study investigated the extent to which individual traits, social influences, objective risk factors, and demographic characteristics were associated with women's risk perceptions for cardiovascular disease, breast cancer, and lung cancer. Using structural equation modeling, we examined hypothesized associations among 452 younger (ages 18-25 years) and 167 middle-aged (ages 40-64 years) women. A greater number and variety of factors were associated with middle-aged women's risk perceptions compared to younger women. For both groups, some objective risk factors were associated with risk perceptions; yet, associations also existed between multiple psychosocial variables (optimism, health locus of control, social exposure to disease, perceived stigma) and risk perceptions. Results suggested that women may base their risk estimates on factors beyond those considered important by healthcare providers.

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.

This study addressed the factors influencing smokers' information seeking pertaining to the health risks of smoking. In particular, this study aimed to extend the risk information seeking and processing model by taking into account the role of autonomous motivations used to stimulate smokers' information-seeking behavior. The results of a Web-based survey indicated that information insufficiency was positively associated with health information-seeking behavior and that negative affective responses were positively associated with information insufficiency and health information-seeking behavior. In addition, autonomous motivations were positively associated with information insufficiency and information-seeking behavior. The results indicated that risk perception was positively related to autonomous motivations and negative affective response. Finally, informational subjective norm was positively related to autonomous motivations and negative affective responses. The implications of this study for future research are discussed.

The aims of this study were to adapt the Job Factors Questionnaire to the field of dentistry, evaluate its psychometric properties, evaluate dental students' perceptions of work/study risk factors for musculoskeletal disorders, and determine the influence of gender and academic level on those perceptions. All 580 students enrolled in two Brazilian dental schools in 2015 were invited to participate in the study. A three-factor structure (Repetitiveness, Work Posture, and External Factors) was tested through confirmatory factor analysis. Convergent validity was estimated using the average variance extracted (AVE), discriminant validity was based on the correlational analysis of the factors, and reliability was assessed. A causal model was created using structural equation modeling to evaluate the influence of gender and academic level on students' perceptions. A total of 480 students completed the questionnaire for an 83% response rate. The responding students' average age was 21.6 years (SD=2.98), and 74.8% were women. Higher scores were observed on the Work Posture factor items. The refined model presented proper fit to the studied sample. Convergent validity was compromised only for External Factors (AVE=0.47), and discriminant validity was compromised for Work Posture and External Factors (r 2 =0.69). Reliability was adequate. Academic level did not have a significant impact on the factors, but the women students exhibited greater perception. Overall, the adaptation resulted in a useful instrument for assessing perceptions of risk factors for musculoskeletal disorders. Gender was found to significantly influence all three factors, with women showing greater perception of the risk factors.

A 20-year-old female college cross-country runner developed chest pain and dyspnea that increased with running. A chest radiograph revealed a right-side pleural effusion, and a ventilation-perfusion scan indicated a probable pulmonary embolism. The diagnosis was left-side pulmonary emboli. Testing for genetic risk factors was negative, leaving oral contraceptive use as the likely cause of the condition. The patient was treated with anticoagulant drugs and discontinuation of oral contraceptives, and was allowed to resume running gradually. Discussion covers genetic and other risk factors, anticoagulation therapy, and return to play.
Full Text Available This paper determines and ranks financial risk factors in Iranian corporations, using analytical hierarchy process (AHP. The present research includes one main question and four sub- questions. Its universe population includes managers, production and financial personnel of great corporations activating in Tehran Stock Exchange, who were selected to explain importance and weight of economic risks indices. The source of great corporations recognition is the Companies Registration Organization in Tehran Province, and according to this, there are 120 corporations. The results have indicated that financing risk maintains the highest priority followed by credit risk, liquidity risk, inflation risk and exchange risk. In terms of different risks associated with financing risk, risk of profit per share has been the number one priority followed by the risk of divisional profit per share, the risk of recessionary or boom and the risk of increasing partial pay profit rate. In terms of credit risk, the risk of loan has been number one priority followed by the risk of inability of loan payment and interest payment. Liquidity risk is another risk factor where demand has been the most important factor followed by rules and regulations and inflation risk. In terms of inflation, producers price risk has been the most important factor followed by consumer price risk, gross domestic product and producers price risk. Finally, in terms of different factors influencing exchange risk, export related issues are considered as the most important factors.
Full Text Available All the economical entities operate in a complex economic environment marked by economic crisis and stressed the growing dynamism in terms of intensifying competition. In our opinion, changing the environment and enhancing the uncertainty is due to the existence of a number of factors that act as "mutagen" that have the ability to produce mutations environment with a higher frequency of spontaneous mutations. Analysis allows outlining the main factors influencing management approach necessary to increase efficiency and competitiveness of all of this. A proposed solution is to recognize the resilience as a Critical Success Factors for improve risk management.
Familial risk factors are known to play an important role in colorectal cancer (CRC) risk, particularly when the relatives are affected by early-onset cancer. Part of this familial aggregation can be accounted for by inherited forms of colorectal cancer, i.e. familial adenomatous polyposis (less than 1% of all CRC) and hereditary nonpolyposis colorectal cancer (about 3%). Other genetic factors may be involved in the development of adenoma or in the transformation of adenoma into carcinoma. That the existence of polymorphisms of the adenomatous polyposis coli gene increase susceptibility to both adenomas and cancer favours this hypothesis. Interactions between environmental factors, and most of all dietary factors, and polymorphisms of carcinogen-metabolizing enzymes may also be involved. Better knowledge of these mechanisms will substantially widen the scope of colorectal cancer prevention.

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.

Natural pieces of wood provide a variety of ecosystem functions in streams including habitat, organic matter retention, increased hyporheic exchange and transient storage, and enhanced hydraulic and geomorphic heterogeneity. Wood mobilization is a critical process in determining the residence time of wood. We documented the characteristics and locations of 865 natural wood pieces (>0.05 m in diameter for a portion >1 m in length) in nine streams along the north shore of Lake Superior in Minnesota. We determined the locations of the pieces again after an overbank stormflow event to determine the factors that influenced mobilization of stationary wood pieces in natural streams. Seven of 11 potential predictor variables were identified with multiple logistic regression as significant to mobilization: burial, effective depth, ratio of piece length to effective stream width (length ratio), bracing, rootwad presence, downstream force ratio, and draft ratio. The final model (P r2 = 0.39) indicated that wood mobilization under natural conditions is a complex function of both mechanical factors (burial, length ratio, bracing, rootwad presence, draft ratio) and hydraulic factors (effective depth, downstream force ratio). If stable pieces are a goal for stream management then features such as partial burial, low effective depth, high length relative to channel width, bracing against other objects (e.g., stream banks, trees, rocks, or larger wood pieces), and rootwads are desirable. Using the model equation from this study, stewards of natural resources can better manage in-stream wood for the benefit of stream ecosystems.
Full Text Available Nowadays, the number of new food products has increased considerably. Nevertheless, not all new food products are accepted and understood by consumers, the innovations in the food sector are often not well received by the market, partly due to a phenomenon known as food neophobia. Food neophobia, a general aversion to try new or unfamiliar foods, has a major impact on preferences, selection and food product acceptability. The neophobic consumers tend to display negative attitudes and less pleasure in relation to new food products. Food neophobia is based on three main reasons for rejection of a food, such as: dislike of its sensory characteristics, fear of negative consequences of eating it, and disgust arising from the idea of the food’s nature or origin. Phobia towards the introduction of unfamiliar foods in the diet can occur for several different factors, such as: socio-demographic characteristics, education level and lifestyle, degree of urbanization, income level, arousal, personal experiences, advertising, fashion, advices of other persons, and habits. This review paper was designed to provide up-to-date relevant information on factors influencing food neophobia, like social factors, type of new food, education, and arousal. The scientific information presented here could help food scientists in new food development, and food companies to develop the best marketing strategies that lead to a general decrease in neophobic consumers’ behaviour. The application of appropriate marketing strategies may allow the product to reach a competitive advantage and be successful.

Full Text Available The term “job satisfaction” is derived from the humanities, psychology and sociology. In the field of psychology, it is a state where an employee has an emotional perception of his situation and reacts with feelings of pleasure or pain. In sociology, it is considered a variable in different categories related to how each employee evaluates and thinks about his work. Job satisfaction is closely related to the performance and quality of work performed by an employee and, consequently, translates into the success of an organization, because a satisfied employee builds and participates in the success of any organization. This article presents the results of the research conducted by the author in 2012 on a sample of 215 people. Respondents represented different organizations. The aim of the study was to identify and assess the significance of individual factors influencing satisfaction and dissatisfaction with work and demonstrate their impact on the overall assessment of job satisfaction. The study showed that between the weight attributed to individual factors and overall job satisfaction there are many statistically significant correlations referring mainly to selected on the basis of analysis respondents’ groups. The study confirms the raised thesis concerning the validity of research in the factors affecting the general feeling of satisfaction by the employees.

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

Down syndrome is a genetic condition that contributes to a significantly shorter life expectancy compared with the general population. We investigated the most common comorbidities in a population of acute hospital patients with Down syndrome and further explored what the most common risk factors for mortality are within this population. From our database of one million patients admitted to National Health Service (NHS) Trusts in northern England, we identified 558 people who had Down syndrome. We compared this group with an age- and gender-matched control group of 5580 people. The most prevalent comorbid diseases within the Down's population were hypothyroidism (22.9%) and epilepsy (20.3%). However, the conditions that had the highest relative risks (RRs) in the Down's population were septal defects and dementia. Respiratory failure, dementia and pneumonia were the most significantly related comorbidities to mortality in the Down syndrome population. In the control population, respiratory failure, dementia and renal failure were the most significant disease contributors. When these contributors were analysed using multivariate analysis, heart failure, respiratory failure, pneumonia and epilepsy were the identified risk factors for in-hospital mortality in the Down syndrome population. Respiratory failure was the sole risk factor for mortality in the Down syndrome population [RR = 9.791 (1.6-59.9) P ≤ 0.05], when compared with the risk factors for mortality in the control population. There is significant medical morbidity in Down syndrome. This morbidity contributes to the lower life expectancy. Respiratory failure is a risk factor for mortality in Down syndrome. We need to thoroughly investigate people with Down syndrome to ensure any treatable illnesses are well managed. © 2015 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

The objective of this study was to estimate risk factors that influence postoperative instability after anterior cruciate ligament (ACL) reconstruction using multivariate logistic regression analysis. A total of 152 consecutive patients with symptomatic ACL insufficiency underwent arthroscopic ACL reconstruction between 2005 and 2011. Loss to follow-up and previous ligament reconstruction were exclusion criteria, resulting in 131 patients remaining for this retrospective study. The median follow-up was 55 months (range 25-100 months). Patients were sorted into two groups by anterior translation on stress radiograph and pivot shift test grade and were analysed for the statistical significance of various risk factors including age at surgery, gender, body mass index, preoperative instability, time from injury to surgery, single-bundle reconstruction with preserved abundant remnant versus double-bundle reconstruction with scanty remnant, and concomitant ligament, meniscus, and articular cartilage injury with use of multivariate logistic regression analysis. Time from injury to surgery over 12 weeks was found to be a significant risk factor for postoperative instability [p ligament (MCL) was also a risk factor (p = 0.02, adjusted OR 13.60; 95 % CI 1.24-148.25). The other variables were not found to be a significant risk factor. Among the risk factor variables, concomitant grade 2 MCL injury and surgical delay of more than 12 weeks from injury were significant risk factors for postoperative knee instability after ACL reconstruction. The overall results suggest that surgery <12 weeks from injury and meticulous attention to concomitant MCL injury should be considered. Retrospective case-control study, Level III.

The occurrence of thyroid diseases is determined by interplay between genetic and environmental factors. The major environmental factor that determines goiter prevalence is iodine status, but other environmental factors influencing entire populations have been identified such as goitrogens in food...... implications for prevention of thyroid disease could be suggested. Discussion of smoking habits should be included in a consultation for goiter with a motivation to quit smoking. Iodine deficiency has particularly strong goitrogenic effects during pregnancy and for the sake of the mother as well as the fetus...

Regeneration in the peripheral nervous system is often incomplete though it is uncertain which factors, such as the type and extent of the injury or the method or timing of repair, determine the degree of functional recovery. Serial electrophysiological techniques were used to follow recovery from...... median nerve lesions (n = 46) in nonhuman primates over 3 to 4 years, a time span comparable with such lesions in humans. Nerve gap distances of 5, 20, or 50mm were repaired with nerve grafts or collagen-based nerve guide tubes, and three electrophysiological outcome measures were followed: (1) compound...... muscle action potentials in the abductor pollicis brevis muscle, (2) the number and size of motor units in reinnervated muscle, and (3) compound sensory action potentials from digital nerve. A statistical model was used to assess the influence of three variables (repair type, nerve gap distance, and time...
Full Text Available Background: There is a shortage of anaesthesiologists in India. The factors that prompt medical students to opt for anaesthesiology as their career are not known; neither do we have any mechanism to know a student′s stress-bearing ability before he/she opts for a stressful career like anaesthesiology. We conducted an anonymous, questionnaire-based, cross-sectional survey among 200 post-graduate anaesthesiology students to know various factors that they considered while opting for this speciality, and also evaluated their stress-bearing ability using Antonovsky′s 13-point sense of coherence scale. Methods: Two-hundred anaesthesiology students were asked to complete a questionnaire regarding the factors they considered important while opting for anaesthesiology, also enumerated in order of importance the three most important factors that led to opting this career. Students also answered the questions in Antonovsky′s sense of coherence (SOC scale. Results: Economic security was considered by maximum number of students (67.7%, while intellectual stimulation/challenge offered by anaesthesiology was rated first in order of importance. Influence of doctor−patient relationship was not considered by large number of students. The weak SOC score (55 (25 th percentile was not greatly different than the mean SOC score (60 in the survey. Conclusion: Increasing the exposure of students to anaesthesiology at undergraduate level and building public awareness about the speciality will prompt more students to opt for the speciality, while career counselling with regard to specific needs of a speciality and ability of a student will help in opting the speciality that best suits the student′s personality.

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. Keywords: pregnancy, treatment, risk reduction, prediction

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.

Degradation and sorption of six acidic pesticides (2,4-D, dicamba, fluroxypyr, fluazifop-P, metsulfuron-methyl, and flupyrsulfuron-methyl) and four basic pesticides (metribuzin, terbutryn, pirimicarb, and fenpropimorph) were determined in nine temperate soils. Results were submitted to statistical analyses against a wide range of soil and pesticide properties to (i) identify any commonalities in factors influencing rate of degradation and (ii) determine whether there was any link between sorption and degradation processes for the compounds and soils studied. There were some marked differences between the soils in their ability to degrade the different pesticides. The parameters selected to explain variations in degradation rates depended on the soil-pesticide combination. The lack of consistent behavior renders a global approach to prediction of degradation unrealistic. The soil organic carbon content generally had a positive influence on degradation. The relationship between pH and degradation rates depended on the dominant mode of degradation for each pesticide. There were positive relationships between sorption and rate of degradation for metsulfuron-methyl, pirimicarb, and all acidic pesticides considered together (all P pesticides.

The design and construction of a vault for used nuclear fuel in crystalline rock may be influenced by a number of geochemical factors. During the siting stage, information is needed regarding the rock type, heterogeneities in its composition and the mineralogy of permeable zones because these will cause variations in thermal conductivity, strength and radionuclide sorptive properties of the rock. These factors may affect decisions regarding depth of vault construction, tunnel dimensions and spacing of panels and waste containers. The decision on whether groundwaters are allowed to flow freely into a planned excavation may depend on measurements of their chemical compositions, microbiological contents and presence of hazardous or corrosive constituents. During site characterization, borehole drilling from the surface and subsequent hydraulic testing will introduce both chemical and microbiological contaminants that may further influence this decision. During vault construction, the geochemistry of the rock may cause changes to the characterization, design and construction of the vault. For example, high salinity fluids in micropores in the rock could prevent the use of radar surveys to detect fractures in the surrounding rock. High rock salinity may also cause unacceptably high total dissolved solids loadings in water discharged from the facility. Again, the presence of toxic, corrosive or radioactive constituents in inflowing groundwater may require grouting or, if inflow is needed for service operations, development of treatment facilities both above and below ground. In addition, the use of explosives will cause high organic and nitrate loadings in service water as well as the possible impregnation of these chemicals in the damaged wall-rock surrounding an excavation. These chemicals may remain despite cleaning efforts and act as nutrients to promote microbial activity in the post-closure phase. In the operational phase, further design and construction, changes

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.
