The association between ABO blood groups and intracranial aneurysms is not well-known. Many co-morbid factors are associated with intracranial aneurysms. Our objective was to assess the prevalence of different blood group in patients with intracranial aneurysm and to look for associations between risk factors and these groups. This retrospective study includes 1,491 cases who underwent surgical operations for intracranial aneurysms from 1993-2014. We have evaluated the information related to clinical history, ABO blood groups and associated risk factors in the patients both ruptured and unruptured intracranial aneurysms by chart review of the cases. In our study, out of 1,491 cases, the most common ABO blood groups were group O (668 cases, 44.80%) and Group A (603 cases, 40.44%), and Rh(+) in 1,319 (88.4%) and Rh(-) in 147 (11.6%). Blood Group A (43% vs. 36%) and Group B (16.2% vs. 8.6%) were significantly higher in Caucasian and African Americans respectively. However, in general population, there was no significant difference in blood groups between Caucasians and African Americans. Rh(-) factor was significantly higher in Caucasians compared to African Americans. Incidence of smoking was significantly higher in aneurysm patients with O group compared to others. In addition, incidence of hypercholesterolemia was significantly higher in aneurysm patients with A group compared to others. The racial disparity in the distribution of blood groups, and risk factor association with blood groups in the development of intracranial aneurysm needs to be considered. The findings from our study may be useful in identifying patients at increased risk. Further study may be required to establish the risks from multiple centers studies around the world.

Risk factors affecting infants and young children, such as mother's drug addiction or teenage pregnancy, are discussed. Four major groups of risk factors are considered: (1) sociocultural and demographic factors; (2) biomedical risks; (3) personal-social risk factors; and (4) family history factors. These risk factors intersect to increase…

Defining Risk Groups to Yellow Fever Vaccine-Associated Viscerotropic Disease in the Absence of Denominator Data

Several risk groups are known for the rare but serious, frequently fatal, viscerotropic reactions following live yellow fever virus vaccine (YEL-AVD). Establishing additional risk groups is hampered by ignorance of the numbers of vaccinees in factor-specific risk groups thus preventing their use as denominators in odds ratios (ORs). Here, we use an equation to calculate ORs using the prevalence of the factor-specific risk group in the population who remain well. The 95% confidence limits and P values can also be calculated. Moreover, if the estimate of the prevalence is imprecise, discrimination analysis can indicate the prevalence at which the confidence interval results in an OR of ∼1 revealing if the prevalence might be higher without yielding a non-significant result. These methods confirm some potential risk groups for YEL-AVD and cast doubt on another. They should prove useful in situations in which factor-specific risk group denominator data are not available.

Benefit of low-dose aspirin for primary prevention of cardiovascular events in diabetes remains controversial. The American Diabetes Association (ADA), the American Heart Association (AHA), and the American College of Cardiology Foundation (ACCF) recommend aspirin for high-risk diabetic patients: older patients with additional cardiovascular risk factors. We evaluated aspirin's benefit in Japanese diabetic patients stratified by cardiovascular risk. In the JPAD trial, we enrolled 2,539 Japanese patients with type 2 diabetes and no history of cardiovascular disease. We randomly assigned them to aspirin (81-100 mg daily) or no aspirin groups. The median follow-up period was 4.4 years. We stratified the patients into high-risk or low-risk groups, according to the US recommendation: age (older; younger) and coexisting cardiovascular risk factors. The risk factors included smoking, hypertension, dyslipidemia, family history of coronary artery disease, and proteinuria. Most of the patients were classified into the high-risk group, consisting of older patients with risk factors (n=1,804). The incidence of cardiovascular events was higher in this group, but aspirin did not reduce cardiovascular events (hazard ratio [HR], 0.83; 95% confidence interval [CI]: 0.58-1.17). In the low-risk group, consisting of older patients without risk factors and younger patients (n=728), aspirin did not reduce cardiovascular events (HR, 0.55; 95% CI: 0.23-1.21). These results were unchanged after adjusting for potential confounding factors. Low-dose aspirin is not beneficial in Japanese diabetic patients at high risk.

To clarify whether high-risk esophageal varices (EVs) influence outcomes in hepatocellular carcinoma (HCC) patients and to determine whether prophylactic endoscopic therapies(PETs) provide benefits for such patients. Ninety-six consecutive patients with naive HCC complicated by EVs were analyzed. Patients with low-risk EVs (group A, n=53), those with high-risk EVs not treated with PETs (group B, n=31), and those with high-risk EVs treated with PETs (group C, n=12) were compared with respect to first bleeding and mortality. Furthermore, factors associated with outcomes were examined. The first bleeding rates were higher in group B than in group A; the survival rates were lower in group B than in group A. High-risk EVs and advanced stage HCC were risk factors for both outcomes in groups A and B. By contrast, the first bleeding rates tended to be lower in group C than in group B, while the survival rates did not significantly differ. In groups B and C, advanced stage HCC was a risk factor for both outcomes, whereas PETs significantly decreased first bleeding. High-risk EVs negatively influence both first bleeding and mortality in HCC patients and PETs may have a preventive effect on bleeding.

In order to evaluate disturbances of the respiratory control in the first year of life in children with a statistically enhanced risk of SIDS, substance P-like immunoreactivity (SPLI) in plasma and mean apnoea duration (MA) were examined. 4 groups of infants were investigated: Controls, full-term infants with anamnestic SIDS-risk factors, preterm infants with additional risk factors and preterm infants without such factors. Infants aged from -4(corrected age) to 63 weeks. SPLI in plasma was determined by a specific, homologous radioimmunoassay. The SPLI-level was significantly higher in controls (n = 41; means +/- SE = 36.37 +/- 4.86 pg/ml) than in preterm infants without (n = 21; 25.41 +/- 5.54 pg/ml) or with additional anamnestic risk factors (n = 111; 25.89 +/- 3.09 pg/ml). SPLI was higher in full-term SIDS-risk infants (n = 150; 30.73 +/- 2.35 pg/ml) than in the preterm groups. There is a significant age dependence in the groups full-term SIDS-risk infants and preterm infants with additional risk factors. During maturation the SPLI-level in plasma rises in these groups from lower values. The MA-values were determined by means of a daytime polygraphy. There is an age dependence of the MA-values during active sleep in full-term SIDS-risk infants and in preterm infants with additional anamnestic risk factors. In the age group 4-17 weeks (peak of SIDS frequency) in active sleep the MA-values were significantly higher in all 3 risk groups than in the controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Sorbe, Bengt

2012-01-01

Background. The aim was to evaluate predictive and prognostic factors in a large consecutive series of endometrial carcinomas and to discuss pre- and postoperative risk groups based on these factors. Material and Methods. In a consecutive series of 4,543 endometrial carcinomas predictive and prognostic factors were analyzed with regard to recurrence rate and survival. The patients were treated with primary surgery and adjuvant radiotherapy. Two preoperative and three postoperative risk groups were defined. DNA ploidy was included in the definitions. Eight predictive or prognostic factors were used in multivariate analyses. Results. The overall recurrence rate of the complete series was 11.4%. Median time to relapse was 19.7 months. In a multivariate logistic regression analysis, FIGO grade, myometrial infiltration, and DNA ploidy were independent and statistically predictive factors with regard to recurrence rate. The 5-year overall survival rate was 73%. Tumor stage was the single most important factor with FIGO grade on the second place. DNA ploidy was also a significant prognostic factor. In the preoperative risk group definitions three factors were used: histology, FIGO grade, and DNA ploidy. Conclusions. DNA ploidy was an important and significant predictive and prognostic factor and should be used both in preoperative and postoperative risk group definitions. PMID:23209924

To determine the differences and trends in the prevalence, awareness, treatment and control of cardiovascular risk factors and lifestyle variables across educational level in the 1995-2005 period in a country with a universal free health care system. Data from three consecutive independent population-based surveys were used. Cardiovascular risk factors, lifestyle variables, and self-reported educational level were collected in 9646 individuals ages 35-74 years throughout the decade. The prevalence of hypertension and diabetes was inversely associated with education. An increase in the proportion of hypertension and dyslipidemia awareness, treatment, and control in all educational level groups was observed. This increase was greater among the lowest education group, reducing the disparities between groups. The prevalence of lifestyle-related risk factors decreased in the greatest but increased in the lowest education group, widening the disparities between groups. A universal free health care system is effective in avoiding inequalities in the diagnosis, treatment, and control of cardiovascular risk factors. However, other social determinants seem to explain the social inequalities in the prevalence of these risk factors and in the adoption of healthy lifestyles. Copyright © 2011 Elsevier Inc.

Worksite health promotion programs use health risk appraisal (HRA) surveys to identify employees at increased risk, then provide a range of interventions to encourage high-risk individuals to improve their health. Our objective was to determine how the intensity of intervention after HRA affected cardiovascular risk after 1 year, comparing individual follow-up counseling with environmental supports. 133 employees of Vanderbilt University with cardiovascular risk factors were randomly assigned to worksite HRA plus targeted disease management (DM group) or HRA plus information about worksite health promotion programs (HRA group). The DM group received longitudinal individualized counseling for risk reduction, whereas the HRA group members received one feedback session about their risk factors and information about free worksite health promotion programs. The main outcome measure was the difference between groups in the change in average Framingham risk score from baseline to 1 year. There was no significant baseline difference between groups in the Framingham risk score. Among DM participants, the mean (SD) Framingham risk score decreased by 22.6%; among HRA participants, the mean score rose by 4.3% (P = .017 for the difference between groups). In this study of employees with cardiovascular risk factors, HRA followed by individual counseling was more effective than providing information about free worksite health promotion programs.

The objective of this study is to evaluate the relationship of atheroembolic risk factors with postoperative recovery of renal function after on-clamp partial nephrectomy (PN) with warm ischemia in patients with staged T1-2 renal cell carcinoma (RCC). A total of 234 patients from 2004 to 2012 were included, and their clinicopathologic and operative parameters, including atheroembolic risk factors were reviewed retrospectively. Renal function, as determined by estimated glomerular filtration rate (eGFR) and measurement of serum creatinine level (Cr) at each scheduled follow-up for a median four years, was compared between the high-risk (HR) group (n=49, ≥ five risk factors) and the low-risk (LR) group (n=185, < five risk factors). Except for baseline renal function and number of risk factors for atheroembolism, differences in characteristics between groups were comparatively insignificant. At 3 months after the operation, Cr and eGFR differed significantly between the two groups (p < 0.05), but no differences were observed afterward. Significant deterioration from baseline in Cr and eGFR was observed in both groups at 1 month after the operation, with a greater change in the HR group (p < 0.05). From measurement to measurement, significantly faster deterioration in Cr and eGFR was observed in the HR group than in the LR group until 6 months after the operation (Cr: LR, 0.02 mg/dL and HR, 0.13 mg/dL; eGFR: LR, 1.50 mL/min/1.73 m(2) and HR, 6.38 mL/min/1.73 m(2); p < 0.05). The presence of atheroembolic risk factors may negatively influence postoperative recovery of renal function after PN in patients with localized RCC.

To assess knowledge of cardiovascular disease (CVD) risk factors among a group of health screening participants and to compare knowledge between participants with high and low CVD risk. Cross-sectional pilot study. Jonesboro, AR, during June 2007. 121 adult volunteers participating in a community health screening. 34-item self-administered written questionnaire. Ability to identify CVD risk factors and healthy values for CVD risk factors and the differences in these abilities between participants with high and low CVD risk. Participants demonstrated good knowledge of traditional CVD risk factors such as high blood pressure, high cholesterol, lack of exercise, and overweight or obese status. Knowledge of other CVD risk factors and healthy values for major CVD risk factors was limited. Participants with high CVD risk were significantly more likely to correctly identify high triglycerides as a CVD risk factor and to identify healthy values for fasting blood glucose and total cholesterol compared with participants with low CVD risk. Overall, participants lacked knowledge of the risk factor status and healthy values for many CVD risk factors. Participants with high CVD risk may have better knowledge of some CVD risk factors than participants with low CVD risk. These findings highlight the need for more education to improve knowledge in both risk groups.

Abstract Background: Strategies to increase adherence to national dietary and physical activity (PA) guidelines to improve the health in regions such as the Lower Mississippi Delta (LMD) of the United States are needed. Here we explore the cardiometabolic responses to an education and behavior change intervention among overweight and obese adults that adapted the 2010 Dietary Guidelines (DG), with and without a PA component. Methods: White and African American overweight and obese adults were randomized to a DG group (n=61) or a DG+PA group (n=60). Both groups received a 12-week dietary education and behavior change intervention, and the DG+PA group also received a PA education and behavior change intervention with a pedometer. Changes in individual risk factors (blood pressure, fasting glucose, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol) and a continuous cardiometabolic risk score were determined. General linear models compared mean changes between groups, adjusting for covariates. Results: No main effect of intervention group was found in completers (n=99) and those who engaged with ≥80% of the intervention (n=83) for individual risk factors or the continuous risk score. Pooling both groups, those with higher baseline risk factor values realized greater improvements in individual risk factors. Conclusions: Adapting DG did not produce any cardiometabolic benefits, even with a PA component. Although the sample was ostensibly healthy, they were all overweight to mildly obese (body mass index of 25–34.9 kg/m2) and participants with higher baseline risk factor values showed more improvements. Adherence to longer-term behavior change may elicit changes in risk profile, so this should be explored. PMID:25569324

To explore awareness of cancer risk factors in ethnic minority men and women living in England. Cross-sectional survey. Men and women were recruited from the six largest ethnic minority groups in the UK proportional to the population distribution: Indian (n = 467); Pakistani (n = 333); Bangladeshi (n = 126); Caribbean (n = 252); African (n = 216); and Chinese (n = 106). Participants responded to an open-ended question about cancer risk factors. Analyses were adjusted for age, gender, socio-economic class and language. The most commonly cited cancer risk factors were smoking (55%), diet (20%), genetics (20%), drinking alcohol (19%) and lifestyle (17%). On average, participants who were able to name cancer risk factors (91% of respondents) cited 2.13 factors. There were some differences between broad ethnic groups (Asian, Black and Chinese), but fewer differences within them (e.g. between Indian, Pakistani and Bangladeshi, or African and Caribbean). Awareness of risk factors (particularly diet and exercise) was lower in this sample than in previous population representative samples in the UK. Interventions aimed at raising awareness of cancer risk factors are likely to be beneficial across the whole ethnic minority population. Any ethnically targeted interventions should consider risk factor awareness levels as well as cancer risk. Copyright © 2012 The Royal Society for Public Health. Published by Elsevier Ltd.

To identify the risk factors of retinal breaks in patients with the symptom of floaters, and to determine the association between those risk factors and retinal breaks. A retrospective analytic study of 184 patients (55 males and 129 females) that included 220 eyes was conducted. Patient information such as age, symptoms (multiple floaters, flashing), duration of symptom, refractive error, history of cataract surgery, family history of retinal detachment, and complete eye examination were recorded. The patients were divided into two groups, the first group (control group) had symptoms of floaters and no retinal breaks, the second group (retinal breaks group) had symptoms of floaters with retinal breaks. Chi-square test, and the multiple logistic regression were used for statistical analysis. Two hundred twenty eyes, 175 eyes of the control group and 45 eyes of the retinal breaks group were examined and included in this study. The multiple logistic regression analysis revealed that patients with multiple floaters, and floaters and flashing increased the risk of retinal breaks to 5.8 and 4.3 times, respectively, when compared to patients with single floater or floaters alone. Lattice degeneration increased the risk of retinal breaks to 5.9 times when compared to eyes that did not have lattice degeneration. Multiple floaters, flashing and lattice degeneration are risk factors of retinal breaks in patients with symptoms of floaters. Therefore, it is important for the ophthalmologists to be aware of these risk factors and the patients at risk should have follow-up examinations.

A balanced hazard ratio for risk group evaluation from survival data.

PubMed

Branders, Samuel; Dupont, Pierre

2015-07-30

Common clinical studies assess the quality of prognostic factors, such as gene expression signatures, clinical variables or environmental factors, and cluster patients into various risk groups. Typical examples include cancer clinical trials where patients are clustered into high or low risk groups. Whenever applied to survival data analysis, such groups are intended to represent patients with similar survival odds and to select the most appropriate therapy accordingly. The relevance of such risk groups, and of the related prognostic factors, is typically assessed through the computation of a hazard ratio. We first stress three limitations of assessing risk groups through the hazard ratio: (1) it may promote the definition of arbitrarily unbalanced risk groups; (2) an apparently optimal group hazard ratio can be largely inconsistent with the p-value commonly associated to it; and (3) some marginal changes between risk group proportions may lead to highly different hazard ratio values. Those issues could lead to inappropriate comparisons between various prognostic factors. Next, we propose the balanced hazard ratio to solve those issues. This new performance metric keeps an intuitive interpretation and is as simple to compute. We also show how the balanced hazard ratio leads to a natural cut-off choice to define risk groups from continuous risk scores. The proposed methodology is validated through controlled experiments for which a prescribed cut-off value is defined by design. Further results are also reported on several cancer prognosis studies, and the proposed methodology could be applied more generally to assess the quality of any prognostic markers.

The role of lipid profile in predicting the risk of Type 2 diabetes mellitus (T2DM) in children is not clearly established. Our aim is to screen non-diabetic children aged 10-14 years for risk of developing T2DM and evaluate the association of abnormal lipids and socioeconomic status (SES). Data on race/ethnicity, family history, body mass index percentile, blood pressure and presence of neck pigmentation (acanthosis nigricans) were collected from 149 non-diabetic children. Using these factors, children were classified into low risk (<3 risk factors) and high risk (>3 risk factors) groups. Logistic regression model and chi-square tests were used to evaluate the association of blood lipid profile and demographic variables. Independent t-test was used to compare the ratio of Total Cholesterol (TC) and High Density Lipids (HDL) with T2DM risk. 60% of children were at high risk for developing T2DM. HDL (p<0.001), triglycerides (p=0.02) and TC/HDL ratio (p<.001) were significantly abnormal in high risk group. Low SES showed a marginal association with high risk group. There were no gender or age differences between high and low risk groups. The significant determinants associated with high risk group were modifiable factors providing an opportunity for early intervention and prevention. © 2016 The Author(s) Published by S.

Risk factors for invasive epithelial ovarian cancer (IEOC) among Hispanics and African Americans are understudied despite notable differences in incidence relative to non-Hispanic whites. We used multivariate logistic regression to examine parity, oral contraceptive use, tubal ligation, endometriosis, family history of ovarian cancer, and talc use and risk of IEOC among Hispanics (308 cases and 380 controls), African Americans (128 cases and 143 controls), and non-Hispanic whites (1,265 cases and 1,868 controls) using four case-control studies we conducted in Los Angeles County. We expressed each of these factors in the form of increasing risk and calculated population attributable risk percentage (PAR%) estimates for the six risk factors separately and jointly in the three groups. The risk associations with these six well-accepted factors were comparable in the three groups. The significant racial/ethnic differences in the prevalence of these factors and differences in their oophorectomy rates explained 31% of the lower incidence in African Americans compared with non-Hispanic whites, but only 13% of the lower incidence in Hispanics. The PAR%s ranged from 27.5% to 31.0% for no tubal ligation, 15.9% to 22.2% for not using oral contraceptives, and 12.2% to 15.1% for using talc in the three groups. All six risk factors are comparably important in the three groups. Differences in the prevalence of these factors and their oophorectomy rates explained approximately one third of the difference in incidence between African Americans and non-Hispanic whites. Devising strategies to lessen the burden of IEOC will be applicable to all three racial/ethnic groups. ©2015 American Association for Cancer Research.

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

Preeclampsia (PE) is a pregnancy-related disorder characterized by hypertension (HT) and proteinuria noticeable after 20 weeks of gestation. PE is now considered as a cardiovascular disease risk factor and a number of studies have shown that experiencing PE increases the prevalence of various cardiovascular risk factors, such as metabolic syndrome and HT. In this study, we aimed to investigate any possible relationship between the ABO/Rh blood group system and PE in Turkey. In the second part of the study, we examined the relationship between the ABO blood group system and development of HT after PE. A total of 250 patients with PE from Kayseri Training and Research Hospital between 2002 and 2012 were included in the study. Patients were classified according to blood groups (A, B, AB, and O) and Rh status (+/-). There was a significant difference between the patients with PE and the control group in terms of distribution of ABO blood groups and the percentage of group AB was found to be higher in patients with PE compared to the control group (P=0.029). The risk of developing PE was significantly higher in group AB than other blood groups (P=0.006). The risk of developing HT after PE was significantly higher in group O than other blood groups (P=0.004). In this study, we found that the patients with blood group AB have a higher risk for PE. The patients with PE of blood group O are at high risk of developing HT, and Rh factor was identified as another risk at this point and these patients should be closely followed postpartum.

The incidence of acute kidney injury (AKI) rises with age and is associated with multiple risk factors. Here, we compared the risk factors for AKI between younger and older incident diabetic patients to examine the trends in risk alteration for individual factors across different age groups. Between 2007 and 2013, we selected all incident type 2 diabetic adults from the Taiwan National Health Insurance registry, stratified based on age: young (< 65 years), old (≥ 65 but < 75 years), and older-old (≥ 75 years). All factors with potential renal influence (e.g., comorbidities, medications, and diagnostics/procedures) were recorded during the study period, with a nested case-controlled approach utilized to identify independent risk factors for AKI in each age group. Totally, 930,709 type 2 diabetic patients were categorized as young (68.7%), old (17.7%), or older-old (13.6%). Older-old patients showed a significantly higher incidence of AKI than the old and the young groups. Cardiovascular morbidities (hypertension, atrial fibrillation, acute coronary syndrome, and cerebrovascular disease) were shown to increase the risk of AKI, although the risk declined with increasing age. Chronic obstructive pulmonary disease and receiving cardiac catheterization elevated the risk of AKI preferentially in the older-old/old and older-old group, respectively, while the administration of angiotensin-converting enzyme/α-blocker and angiotensin receptor blocker/calcium channel blocker reduced the risk of AKI preferentially in the older-old and older-old/old group, respectively. In conclusion, our findings highlight the importance of devising age-specific risk factor panels for AKI in patients with recently diagnosed type 2 diabetes.

To assess the prevalence of possible risk factors of upper gastrointestinal bleeding (UGIB) and their age-group specific trend among the general population and osteoarthritis patients. We utilized data from the National Health Insurance Service that included claims data and results of the national health check-up program. Comorbid conditions (peptic ulcer, diabetes, liver disease, chronic renal failure, and gastroesophageal reflux disease), concomitant drugs (aspirin, clopidogrel, cilostazol, non-steroidal anti-inflammatory drugs, steroid, anticoagulants, and SSRI), personal habits (smoking, and alcohol consumption) were considered as possible UGIB risk factors. We randomly imputed the prevalence of infection in the data considering the age-specific prevalence of Helicobacter pylori ( H. pylori ) infection in Korea. The prevalence of various UGIB risk factors and the age-group specific trend of the prevalence were identified. Prevalence was compared between osteoarthritis patients and others. A total of 801926 subjects (93855 osteoarthritis patients) aged 20 and above were included. The prevalence of individual and concurrent multiple risk factors became higher as the age increased. The prevalence of each comorbid condition and concomitant drug were higher in osteoarthritis patients. Thirty-five point zero two percent of the overall population and 68.50% of osteoarthritis patients had at least one or more risk factors of UGIB. The prevalence of individual and concurrent multiple risk factors in younger age groups were also substantial. Furthermore, when personal habits (smoking, and alcohol consumption) and H. pylori infection were included, the prevalence of concurrent multiple risk factors increased greatly even in younger age groups. Prevalence of UGIB risk factors was high in elderly population, but was also considerable in younger population. Patient with osteoarthritis was at higher UGIB risk than those without osteoarthritis. Physicians should consider individualized risk assessment regardless of age when prescribing drugs or performing procedures that may increase the risk of UGIB, and take necessary measures to reduce modifiable risk factors such as H. pylori eradication or lifestyle counseling.

Antenatal substance use and related psychosocial risk factors are known to increase the likelihood of child protection involvement; less is known about the predictive nature of maternal reflective functioning (RF) in this population. This preliminary study assessed psychosocial and psychological risk factors for a group of substance dependent women exposed to high risks in pregnancy, and their impact on child protection involvement. Pregnant women on opiate substitution treatment (n = 11) and a comparison group (n = 15) were recruited during their third trimester to complete measures of RF (Pregnancy Interview), childhood trauma, mental health and psychosocial assessments. At postnatal follow-up, RF was reassessed (Parent Development Interview - Revised Short Version) and mother-infant dyads were videotaped to assess emotional availability (EA). Child protection services were contacted to determine if any concerns had been raised for infant safety. Significant between-group differences were observed for demographics, psychosocial factors, trauma and mental health symptoms. Unexpectedly, no significant differences were found for RF or EA between groups. Eight women in the 'exposed to high risks' group became involved with child protection services. Reflective functioning was not significantly associated with psychosocial risk factors, and therefore did not mediate the outcome of child protection involvement. Women 'exposed to high risks' were equally able to generate a model of their own and their infants' mental states and should not be seen within a deficit perspective. Further research is required to better understand the range of risk factors that predict child protection involvement in high risk groups. © The Author(s) 2013.

The aim is to estimate the relative risk and population attributable risk (PAR) of risk factors for ischemic stroke by ethnic group. In this case-control study, cases of first ischemic stroke were taken from the South London Stroke Register and controls from a cross-sectional prevalence survey covering the same area. PAR was determined for each risk factor by ethnic group. Multivariable analysis was used to examine the association between risk factors and ischemic stroke across all ethnic groups. 664 cases and 716 controls aged 45 to 74 years were included, with ethnicity of white 78%:42%, black Caribbean 16%:43%, and black African 6%:15%, respectively. For the white group, high PAR was found for ischemic heart disease (IHD) on ECG (56% [95% CI, 49% to 62%]), obesity (49% [95% CI, 40% to 56%]), hypertension (HT) (38% [95% CI, 29% to 46%]), smoking (31% [95% CI, 19% to 41%]), transient ischemic attack (TIA) (23% [95% CI, 19% to 27%]), and atrial fibrillation (AF) (16% [95% CI, 10% to 21%]). In the black Caribbean compared with the white group, PAR was higher for HT (46% [95% CI, 21% to 63%]) and diabetes mellitus (DM) (29% [95% CI, 14% to 42%]), and lower for current smoking (18% [95% CI, 1% to 32%]) and AF (10% [95% CI, 0% to 18%]). In the black African group HT had a higher PAR (59% [95% CI, 91% to 82%]) than the other groups. PAR for AF (11% [95% CI, -11% to 29%]), obesity (30% [95% CI, -20% to 60%]), and DM (4% [95% CI, -25% to 26%]) was low compared with the other groups. In multivariable analysis, risk factors associated with ischemic stroke included TIA, AF, IHD on ECG, smoking, excess alcohol, obesity, HT, and DM. In the first European case-control study examining risk factors for ischemic stroke in black Caribbean and African populations, some differences were demonstrated in the impact of risk factors between these groups. It may be important to address such differences when developing stroke preventative strategies.

The aim of this study was to find out the risk factors through analysis of seven medical malpractice judgments related to fall injuries. The risk factors were analysed by using the framework that approaches falls from a systems perspective and comprised people, organisational or environmental factors, with each factor being comprised of subfactors. The risk factors found in each of the seven judgments were aggregated into one framework. The risk factors related to patients (i.e. the people factor) were age, pain, related disease, activities and functional status, urination state, cognitive function impairment, past history of fall, blood transfusion, sleep endoscopy state and uncooperative attitude. The risk factors related to the medical staff and caregivers (i.e. people factor) were observation negligence, no fall prevention activities and negligence in managing high-risk group for fall. Organisational risk factors were a lack of workforce, a lack of training, neglecting the management of the high-risk group, neglecting the management of caregivers and the absence of a fall prevention procedure. Regarding the environment, the risk factors were found to be the emergency room, chairs without a backrest and the examination table. Identifying risk factors is essential for preventing fall accidents, since falls are preventable patient-safety incidents. Falls do not happen as a result of a single risk factor. Therefore, a systems approach is effective to identify risk factors, especially organisational and environmental factors.

No previous reports have focused on surgical treatments and risk factors of umbilical hernia alone in peritoneal dialysis (PD) patients. Herein, we evaluated the treatments and risk factors. A total of 411 PD patients were enrolled. Of the 15 patients with umbilical hernia (3.6%), six underwent hernioplasty. There was no recurrence in five patients treated with tension-free hernioplasty. The mean PD vintage after onset of hernia in the hernioplasty group tended to be longer than that in the non-hernioplasty group. An incarcerated hernia occurred in one non-hernioplasty patient. Although the incidence was significantly higher among women (P = 0.02), female sex was not a risk factor for umbilical hernia (P = 0.08). Our findings suggest that umbilical hernias should be repaired for continuing PD. Furthermore, there were no significant risk factors for umbilical hernia in PD patients. Future studies with larger sample groups are required to elucidate these risk factors. © 2015 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

Suicidal Ideation among Afghanistan/Iraq War Veterans remains a health concern. As young Veterans adjust to civilian life, new risk factors might emerge and manifest differently in this group versus those in the general population. We explored these differences. With 2013 National Survey on Drug Use and Health data, we examined differences in risk of past-year suicidal ideation between Veterans of the Afghanistan/Iraq War periods aged 18-34 years (N=328) and age-comparable civilians (N=23,222). We compared groups based on individual and socio-environmental risk factors as well as perceptions of unmet mental healthcare needs. We report adjusted rate ratios (aRRs); interaction terms tested for between-group differences. PY suicidal ideation rates for Veterans and civilians did not differ (52 versus 59 per 1,000, p=0.60) and both groups shared many risk factors. However, drug problems and perceived unmet mental health care needs were vastly stronger risk factors among Veterans versus civilians (interaction terms indicated that the aRRs were 3.8-8.0 times higher for Veterans versus civilians). Other differences were discovered as well. Past-year suicidal ideation rates did not differ by Veteran status among young adults. However, different risk factors per group were detected, which can inform Veteran suicide prevention efforts. Published by Elsevier Ireland Ltd.

We aimed to find out the effect of abortus imminens (AI) on obstetric outcomes of pregnancies which continued beyond the 24th week of gestation. In this prospective study, 309 patients with AI were divided into high-risk group (with a risk factor for spontaneous abortus) (n = 92) and low-risk group (without a risk factor) (n = 217). The control group (n = 308) was chosen randomly. In AI group, preterm delivery, preterm premature rupture of membranes (PPROM), cesarean section (C/S) delivery, postpartum uterine atony and need of a neonatal intensive care unit (NICU) rates were significantly higher than control group. Gestational diabetes mellitus, PPROM, still birth, low APGAR scores were seen more frequently in the high-risk patients than in the control group. Furthermore in the high-risk group, preterm delivery, malpresentation, C/S delivery and need of NICU were increased much more than in the low-risk group. Gestational hypertension/preeclampsia, oligo/polyhydramniosis, intrauterine growth retardation, placenta previa, abruption of placenta, chorioamnionitis, congenital abnormalities, delivery induction, cephalopelvic disproportion, fetal distress and manual removal of placenta were not different among the groups. Patients with AI history, especially with high-risk factors can have adverse obstetric and neonatal results. So their antenatal follow-up has to be done cautiously for the early signs and symptoms of these complications.

The prevalence of gastroesophageal reflux disease in Korea has been believed to be low, but the incidence of gastroesophageal reflux disease in Korea is expected to increase because of the longer life expectancy and more ingestion of westernized food. The aim of this study was to report differences in the risk factors of reflux esophagitis (RE) according to age in Korea. We prospectively recruited the subjects who had RE among those who visited a health promotion center for upper gastrointestinal cancer surveillance at Hallym Medical Center (five institutions) between January 2008 and February 2009. The enrolled study participants comprised 742 subjects with RE and 1484 healthy controls. The independent risk factors of RE in young and adult group were male sex, smoking, coffee, body mass index ≥ 25, hiatal hernia, and Helicobacter pylori negativity. The risk factors of RE in elderly group were smoking, coffee, and hiatal hernia. The risk factors for RE according to age group were found to differ. In elderly group, Helicobacter pylori infection was not a significant protective factor contrary to young and adult groups. © 2012 Copyright the Authors.

Objective To recalibrate an existing Framingham risk score to produce a web‐based tool for estimating the 10‐year risk of coronary heart disease (CHD) and cardiovascular disease (CVD) in seven British black and minority ethnic groups. Design Risk prediction models were recalibrated against survey data on ethnic group risk factors and disease prevalence compared with the general population. Ethnic‐ and sex‐specific 10‐year risks of CHD and CVD, at the means of the risk factors for each ethnic group, were calculated from the product of the incidence rate in the general population and the prevalence ratios for each ethnic group. Setting Two community‐based surveys. Participants 3778 men and 4544 women, aged 35–54, from the Health Surveys for England 1998 and 1999 and the Wandsworth Heart and Stroke Study. Main outcome measures 10‐year risk of CHD and CVD. Results 10‐year risk of CHD and CVD for non‐smoking people aged 50 years with a systolic blood pressure of 130 mm Hg and a total cholesterol to high density lipoprotein cholesterol ratio of 4.2 was highest in men for those of Pakistani and Bangladeshi origin (CVD risk 12.6% and 12.8%, respectively). CHD risk in men with the same risk factor values was lowest in Caribbeans (2.8%) and CVD risk was lowest in Chinese (5.4%). Women of Pakistani origin were at highest risk and Chinese women at lowest risk for both outcomes with CVD risks of 6.6% and 1.2%, respectively. A web‐based risk calculator (ETHRISK) allows 10‐year risks to be estimated in routine primary care settings for relevant risk factor and ethnic group combinations. Conclusions In the absence of cohort studies in the UK that include significant numbers of black and minority ethnic groups, this risk score provides a pragmatic solution to including people from diverse ethnic backgrounds in the primary prevention of CVD.

The primary purpose of this study was to develop a simpler prognostic model to predict overall survival for patients treated for metastatic renal cell carcinoma (mRCC) by examining variables shown in the literature to be associated with survival. We conducted a retrospective analysis of patients treated for mRCC at two Canadian centres. All patients who started first-line treatment were included in the analysis. A multivariate Cox proportional hazards regression model was constructed using a stepwise procedure. Patients were assigned to risk groups depending on how many of the three risk factors from the final multivariate model they had. There were three risk factors in the final multivariate model: hemoglobin, prior nephrectomy, and time from diagnosis to treatment. Patients in the high-risk group (two or three risk factors) had a median survival of 5.9 months, while those in the intermediate-risk group (one risk factor) had a median survival of 16.2 months, and those in the low-risk group (no risk factors) had a median survival of 50.6 months. In multivariate analysis, shorter survival times were associated with hemoglobin below the lower limit of normal, absence of prior nephrectomy, and initiation of treatment within one year of diagnosis.

Risk of cardiovascular disease varies between ethnic groups and the aim of this study was to investigate differences in cardiovascular risk factors, and total cardiovascular risk between ethnic groups in Norway. Cross-sectional study using data from the Cohort of Norway (CONOR). A sample of 62,145 participants, 40-65 years of age, originating from 11 geographical regions, were included in our study. Self-reported variables, blood samples and physical measurements were used to estimate age- and time-adjusted mean values of cardiovascular risk factors for different ethnic groups. The 10-year risks of cardiovascular mortality and cardiovascular events were calculated using the Framingham and NORRISK risk models. We observed differences between ethnic groups for cardiovascular risk factors and both Framingham and NORRISK risk scores. NORRISK showed significant differences by ethnicity in women only. Immigrants from the Indian subcontinent had the lowest high-density lipoprotein (HDL) levels, the highest levels of blood glucose, triglycerides, total cholesterol/HDL ratio, waist hip ratio and diabetes prevalence. Immigrants from the former Yugoslavia had the highest Framingham scores, high blood pressure, high total cholesterol/HDL ratio, overweight measures and smoking. Low cardiovascular risk was observed among East Asian immigrants. The previously reported excess cardiovascular risk among immigrants from the Indian subcontinent was supported in this study. We also showed that immigrants from the former Yugoslavian countries had a higher total 10-year risk of cardiovascular events than other ethnic groups. This study adds information about ethnic groups in Norway which needs to be addressed in further research and targeted prevention strategies.

Certain occupational groups are known to be at particularly high risk of developing allergic diseases. The objective of the present study was to evaluate the prevalence of allergic diseases among working adolescents. The International Study of Asthma and Allergies in Childhood questionnaire was used. Four hundred and thirty six adolescents working in motor, lathe-finish, coiffure and textile and 366 high school students as control group were enrolled to the study. Mean age was 16.8 +/- 1.2 years and 82.9% of them were male. There was no significant difference among groups for ever and current wheezing while doctor diagnosed asthma was higher in lathe- finish group (p = 0.036). Family history of allergy, history of allergic rhinitis, and active smoking were found to be risk factors for asthma and related symptoms. Working in coiffure (p = 0.054), and textile (p = 0.003) were significant risk factors for ever allergic rhinitis. Working in lathe finish (p = 0.023), coiffure (p = .002), and textile (p < 0.001) were associated with a higher risk for current allergic rhinitis. Working in coiffure was a risk factor for ever eczema (p = 0.008) and doctor diagnosed eczema (p = 0.014). It was concluded that working in lathe-finish was associated with doctor diagnosed asthma and active smoking was a risk factor for asthma and related symptoms. Working in coiffure, textile and lathe- finish were risk factors for rhinitis, and working in coiffure was a risk factor for eczema. Preventive measures should be taken at the onset of employment in order to prevent or reduce the detrimental effects of exposures in these occupational groups.

To explore the effect of community nursing intervention on awareness regarding primary prevention knowledge, self-management, and risk factors for coronary heart disease (CHD) in Hengyang City, Hunan Province. A total of 120 individuals at high risk of CHD were recruited and divided into a control group and an intervention group. The intervention group was given the health knowledge lecture and individual community nursing intervention. The control group was given the routine management. Before and after the intervention, all of the recruiters were evaluated by the awareness on primary prevention knowledge, self-management and risk factors for CHD. Before the intervention, there was no significant difference in the demographic data, the cognitive levels regarding primary prevention knowledge, the self-management and the risk factors for CHD between the 2 groups (P>0.05). After the intervention, the cognitive levels regarding primary prevention knowledge, the self-management and the risk factors for CHD between the 2 groups changed. In the intervention group, the cognitive level was significantly increased (P<0.05); the self management score was improved; the systolic blood pressure, BMI, and the levels of fasting glucose, TC and low density lipoprotein-cholesterol were significantly decreased and the level of high density lipoprotein-cholesterol was significantly increased (P<0.05). There was no significant difference in the above-mentioned parameters between before and after intervention in the control group (P>0.05). The cognitive levels regarding primary prevention knowledge and self-management for CHD can be improved effectively by community nursing intervention in high-risk population of CHD, and the risk factors for CHD can also be reduced.

It is widely believed that risk factors identified in previous epidemiologic studies accurately predict adolescent drug use. Comparative studies are needed to determine how risk factors vary in prevalence, distribution, sensitivity, and pattern across the major US ethnic/racial groups. Baseline questionnaire data from a 3-year epidemiologic study of early adolescent development and drug use were used to conduct bivariate and multivariate risk factor analyses. Respondents (n = 6760) were sixth- and seventh-grade Cuban, other Hispanic, Black, and White non-Hispanic boys in the 48 middle schools of the greater Miami (Dade County) area. Findings indicate 5% lifetime illicit drug use, 4% lifetime inhalant use, 37% lifetime alcohol use, and 21% lifetime tobacco use, with important intergroup differences. Monotonic relationships were found between 10 risk factors and alcohol and illicit drug use. Individual risk factors were distributed disproportionately, and sensitivity and patterning of risk factors varied widely by ethnic/racial subsample. While the cumulative prevalence of risk factors bears a monotonic relationship to drug use, ethnic/racial differences in risk factor profiles, especially for Blacks, suggest differential predictive value based on cultural differences.

Background Radiofrequency ablation (RFA) and microwave ablation (MWA) are the most frequently used thermal ablation methods for the treatment of liver cancer. Liver abscess is a common and severe complication of thermal ablation treatment. Objectives The objective of this study was to determine the incidence and risk factors of liver abscess formation after thermal ablation of liver cancer. Materials and Methods The clinical data of 423 patients who underwent 691 thermal ablation procedures for liver cancer were collected in order to retrospectively analyze the basic characteristics, incidence, and risk factors associated with liver abscess formation. Patients with multiple risk factors for liver abscess formation were enrolled in a risk factor group, and patients with no risk factors were enrolled in a control group. The chi-square test and multiple logistic regression analysis were used to analyze the relationship between the occurrence of liver abscesses and potential risk factors. Results Two hundred and eight patients underwent 385 RFA procedures, and 185 patients underwent 306 MWA procedures. The total incidence of liver abscesses was 1.7%, while the rates in the RFA group (1.8%) and MWA groups (1.6%) were similar (P > 0.05). The rates of liver abscesses in patients who had child-pugh class B and class C cirrhosis (P = 0.0486), biliary tract disease (P = 0.0305), diabetes mellitus (P = 0.0344), and porta hepatis tumors (P = 0.0123) were 4.0%, 6.7%, 6.5%, and 13.0%, respectively. There was a statistically significant difference between these four groups and the control group (all P < 0.05). The incidence of liver abscesses in the combined ablation and percutaneous ethanol injection (PEI) group (P = 0.0026) was significantly lower than that of the ablation group (P < 0.05). Conclusions The incidence of liver abscesses after liver cancer thermal ablation is low. Child-Pugh Class B and Class C cirrhosis, biliary tract disease, diabetes mellitus, and porta hepatis tumors are four significant risk factors. Combined ablation and PEI reduces the rate of liver abscesses. PMID:27642345

The clinical significance of the number of aspiration risk factors in patients with pneumonia is unknown as yet. In the present study, we clarify the significance of the number of aspiration risk factors for mortality and recurrence in pneumonia patients. This study included 322 patients hospitalized with pneumonia between December 2014 and June 2016. We investigated associations between the number of aspiration risk factors present (orientation disturbance, bedridden, chronic cerebrovascular disease, dementia, sleeping medications and gastroesophageal disease) and 30-day and 6-month mortality, and pneumonia recurrence within 30 days. Patients were categorized by number of risk factors present into groups of 0-1, 2, 3, and 4 or more. Of a total of 322 patients, 93 (28.9%) had 0-1 risk factors, 112 (34.8%) had 2, 88 (27.3%) had 3, and 29 (9.0%) had 4 or more risk factors. The percentages of patients with recurrence of pneumonia were 13.0%, 33.0%, 43.2%, and 54.2% in the 0-1, 2, 3, and 4 or more risk factor groups, respectively. The percentages of patients with 30-day mortality were 2.2%, 5.4%, 11.4%, and 24.1%, and those of patients with 6-month mortality were 6.6%, 24.5%, 30.7%, and 50.0%, in the 0-1, 2, 3, and 4 or more risk factor groups, respectively. The number of aspiration risk factors was associated with increases in both mortality and recurrence in pneumonia patients. Therefore, in clinical practice, physicians should consider not only the presence of aspiration risks but also the number of aspiration risk factors in these patients.

Previous research has identified modifiable risk factors for Alzheimer's disease (AD) in older adults. Research is limited on the potential link between these risk factors and subjective memory impairment (SMI), which may precede AD and other dementias. Examination of these potential relationships may help identify those at risk for AD at a stage when interventions may delay or prevent further memory problems. The objective of this study was to determine whether risk factors for AD are associated with SMI among different age groups. Trained interviewers conducted daily telephone surveys (Gallup-Healthways) of a representative community sample of 18,614 U.S. respondents, including 4,425 younger (age 18 to 39 years), 6,365 middle-aged (40 to 59 years), and 7,824 older (60 to 99 years) adults. The surveyors collected data on demographics, lifestyles, and medical information. Less education, smoking, hypertension, diabetes, less exercise, obesity and depression, and interactions among them, were examined for associations with SMI. Weighted logistic regressions and chi-square tests were used to calculate odds ratios and confidence intervals for SMI with each risk factor and pairwise interactions across age groups. Depression, less education, less exercise, and hypertension were significantly associated with SMI in all three age groups. Several interactions between risk factors were significant in younger and middle-aged adults and influenced their associations with SMI. Frequency of SMI increased with age and number of risk factors. Odds of having SMI increased significantly with just having one risk factor. These results indicate that modifiable risk factors for AD are also associated with SMI, suggesting that these relationships occur in a broad range of ages and may be targeted to mitigate further memory problems. Whether modifying these risk factors reduces SMI and the eventual incidence of AD and other dementias later in life remains to be determined.

There seemed to be characteristic risk factors in cirrhotic patients for posthepatectomy complications because these patients have less hepatic reserve as compared with noncirrhotic patients. The aim of the current study was to identify these characteristic risk factors in cirrhotic patients. We performed 419 primary hepatectomies for hepatocellular carcinoma. The patients were divided into the cirrhotic group (n = 198) and the noncirrhotic group (n = 221), and the risk factors for posthepatectomy complications were compared between the groups. Thirty-six cirrhotic patients (18.2%) experienced Clavien's Grade III or more complications. Tumor size, intraoperative blood loss, duration of operation, major hepatectomy (two or more segments), and necessity of blood transfusion were found to be significant risk factors in univariate analyses. Multivariate analysis revealed that major hepatectomy and intraoperative blood loss were independent risk factors for posthepatectomy complications in patients with cirrhosis. On the other hand, the duration of operation was only an independent risk factor for posthepatectomy complication in noncirrhotic patients. Cirrhotic patients should avoid a major hepatectomy and undergo a limited resection preserving as much liver tissue as possible and meticulous surgical procedures to lessen intraoperative blood loss are mandatory to prevent major posthepatectomy complications.

To investigate the relationship between polymorphism of Ghrelin gene and serum levels of lipoprotein in Han Chinese with or without coronary heart disease (CHD) risk factors. PCR restriction fragment length polymorphism assay was used to detect the distribution of genotypes of Ghrelin gene in 225 Han Chinese (40 to 69 years-old) with CHD risk factors, 78 subjects without CHD risk factors served as normal controls. Serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) and very low-density lipoprotein (VLDL) were measured to analyze the relationship with the polymorphism of Ghrelin gene. Ghrelin genotype frequencies of AA, AG, GG (0.975, 0.025, 0.00 in control group and 0.956, 0.040, 0.004 in the high-risk group, all P > 0.05) as well as the allele frequencies of A, G (0.987, 0.013 in control group and 0.976, 0.024 in the high-risk group, all P > 0.05) were similar between the groups. HDL-C levels of the Arg/Gln carriers were significantly lower than those of Arg/Arg carriers in control group and in the high-risk group (all P < 0.05). Arg/Gln carriers were associated lower HDL-C levels in Han Chinese.

To examine the risk factors of developing functional decline and make probabilistic predictions by using a tree-based method that allows higher order polynomials and interactions of the risk factors. The conditional inference tree analysis, a data mining approach, was used to construct a risk stratification algorithm for developing functional limitation based on BMI and other potential risk factors for disability in 1,951 older adults without functional limitations at baseline (baseline age 73.1 ± 4.2 y). We also analyzed the data with multivariate stepwise logistic regression and compared the two approaches (e.g., cross-validation). Over a mean of 9.2 ± 1.7 years of follow-up, 221 individuals developed functional limitation. Higher BMI, age, and comorbidity were consistently identified as significant risk factors for functional decline using both methods. Based on these factors, individuals were stratified into four risk groups via the conditional inference tree analysis. Compared to the low-risk group, all other groups had a significantly higher risk of developing functional limitation. The odds ratio comparing two extreme categories was 9.09 (95% confidence interval: 4.68, 17.6). Higher BMI, age, and comorbid disease were consistently identified as significant risk factors for functional decline among older individuals across all approaches and analyses. © 2017 The Obesity Society.

We investigated whether the consumption of Korean rice cakes enriched with dietary fiber with or without polyphenol rich plants might decrease the risk factors of metabolic syndrome (MetS). Rice cakes were manufactured using fructooligosaccharides, resistant starch, and psyllium as sources of dietary fibers with and without polyphenol rich Artemisia annua and Gynura procumbens Merr. (RC+FP and RC+F, respectively), and prepared in three forms (songpyeon, seolgidduk, and chaldduk). Ninety subjects with at least one MetS risk factor were recruited for 6 weeks of dietary intervention. Sixty subjects were finally included for the analysis. Compared to the initial values, RC+FP group had decreased levels of fasting blood glucose (FBG), HOMA-IR and blood pressure after 6 weeks, whereas RC+F group didn't have significant changes in them. Regarding the improvement of individual MetS risk factors, RC+FP group showed significant reduction in FBG and blood pressures but RC+F group only had reduction in systolic blood pressure. After the intervention, a reduction in the number of MetS risk factors was greatert in the RC+FP group than in the RC+F group. In conclusion, Dietary fiber enriched rice cakes with or without polyphenols decreased the number and/or the levels of MetS risk factors. Polyphenol rich plant components may provide additional health benefits in controlling FBG and blood pressure.

To identify subgroups of patients with work-related back pain based on disability risk factors. Patients with work-related back pain (N = 528) completed a 16-item questionnaire of potential disability risk factors before their initial medical evaluation. Outcomes of pain, functional limitation, and work disability were assessed 1 and 3 months later. A K-Means cluster analysis of 5 disability risk factors (pain, depressed mood, fear avoidant beliefs, work inflexibility, and poor expectations for recovery) resulted in 4 sub-groups: low risk (n = 182); emotional distress (n = 103); severe pain/fear avoidant (n = 102); and concerns about job accommodation (n = 141). Pain and disability outcomes at follow-up were superior in the low-risk group and poorest in the severe pain/fear avoidant group. Patients with acute back pain can be discriminated into subgroups depending on whether disability is related to pain beliefs, emotional distress, or workplace concerns.

Cigarette smoking remains a substantial threat to the current and future health of America's youth. The purpose of this study was to identify the risk and protective factors for cigarette smoking among US adolescents. Data from the National Longitudinal Study of Adolescent Health was used, comparing the responses of all non-smokers at Time 1 for their ability to predict the likelihood of smoking at Time 2, one year later. Data was stratified into four gender by grade group cohorts. Cross-cutting risk factors for smoking among all four cohorts were: using alcohol, marijuana, and other illicit drugs; violence involvement; having had sex; having friends who smoke and learning problems. Having a higher grade point average and family connectedness were protective across all cohorts. Other gender and grade group specific risk and protective factors were identified. The estimated probability of initiating smoking decreased by 19.2% to 54.1% both in situations of high and low risk as the number of protective factors present increased. Of the factors that predict or protect against smoking some are influential across all gender and grade group cohorts studied, while others are specific to gender and developmental stage. Prevention efforts that target both the reduction of risk factors and enhancement of protective factors at the individual, family, peer group and community are likely to reduce the likelihood of smoking initiation.

The purpose of the present study is to compare risk factors of necrotizing enterocolitis (NEC) between two group: group A, newborns with the disease and group B, newborns with other diseases different from NEC, in order to know if these risk factors are more frequent or not in the first group. We assessed the clinical records of all the patients hospitalized in the Neonatal Intensive Care Unit and Neonatology Service of the La Raza General Hospital between 1987 and 1991 with the diagnosis of NEC. They were compared with 65 clinical records chosen at random of patients hospitalized in the same Unit with other diagnosis at the same time, and who were discharged by improvement or deceased. In all of them were look for known risk factors for NEC generally accepted such as: prematurity, neonatal asphyxia, poliglobulia, cyanotic congenital heart disease, patent ductus arteriosus, respiratory distress syndrome, catheterization of umbilical vessels, early feeding of elevated formula increases, exchange exchange transfusion, hypoxic ischemic encephalopathy, infection, etc. Just 25 records of the possible 50 with the diagnosis of NEC full filled inclusion criteria. There were no statistically significant difference in weight, sex, mortality and known risk factors of NEC between both groups. Were concluded that NEC is a disease of unknown etiology that should be studied more thoroughly. The known risk factors must be avoided because the patient susceptibility probably play an important role.

The purpose of this study was to evaluate the risk factors for tube exposure after glaucoma drainage implant surgery. This was a retrospective case-controlled observational study of 64 eyes from 64 patients. Thirty-two eyes of 32 patients with tube erosion requiring surgical revision were compared with 32 matched control eyes of 32 patients. Univariate and multivariate risk factor analyses were performed. Mean age was significantly younger in the tube exposure group compared with the control group (48.2±28.1 years versus 67.3±18.0 years, respectively; P=0.003). The proportion of diabetic patients (12.5%) in the tube exposure group was significantly less (P=0.041) compared with the control group (37.5%). Comparisons of the type and position of the drainage implant were not significantly different between the two groups. The average time to tube exposure was 17.2±18.0 months after implantation of the drainage device. In both univariate and multivariate analyses, younger age (P=0.005 and P=0.027) and inflammation prior to tube exposure (P≤0.001 and P=0.004) were significant risk factors. Diabetes was a significant risk factor only in the univariate analysis (P=0.027). Younger age and inflammation were significant risk factors for tube exposure after drainage implant surgery.

Limited information is available of effects of rural-to-urban within-country migration on cardiovascular (CV) risk factors in low- and middle- income countries (LMIC). A systematic review of studies evaluating these effects was performed with rural and/or urban control groups. Two teams of investigators searched observational studies in Medline, Web of Science and Scopus until May 2011. Studies evaluating international migration were excluded. Three investigators extracted the information stratified by gender. Information on 17 known CV risk factors was obtained. Eighteen studies (n=58,536) were included. Studies were highly heterogeneous with respect to study design, migrant sampling frame, migrant urban exposure and reported CV risk factors. In migrants, commonly reported CV risk factors-systolic and diastolic blood pressure, body mass index, obesity, total cholesterol and low-density lipoprotein-were usually higher or more common than in the rural group and usually lower or less common than in the urban group. This gradient was usually present in both genders. Anthropometric (waist-to-hip ratio, hip/waist circumference, triceps skinfolds) and metabolic (fasting glucose/insulin, insulin resistance) risk factors usually followed the same gradient, but conclusions were weak as information was insufficient. Hypertension, high-density lipoprotein, fibrinogen and C-reactive protein did not follow any pattern. In LMIC, most but not all, CV risk factors are higher or more common in migrants than in rural groups but lower or less common than in urban groups. Such gradients may or may not be associated with differential CV events and long-term evaluations are necessary.

Non Communicable Diseases (NCDs) are the major causes of mortality and morbidity globally. Awareness about NCDs and their risk factors has an important role in prevention and management strategies of these NCDs. 1) To assess the awareness of risk factors contributing to NCDs among the patients visiting tertiary care hospital in Mysuru district; 2) To compare the difference in awareness of risk factors for NCDs among the urban and rural patients with/ without NCD visiting the tertiary care hospital. A cross- sectional study was conducted in a tertiary care centre- JSS Hospital, Mysuru, Karnataka from March 2013 - August 2013. The patients visiting Medicine OPD during the period were the study subjects. The subjects were allocated into 4 groups: Urban without any NCD, Urban with atleast one NCD, rural without NCD, rural with atleast one NCD. A pretested questionnaire regarding awareness of risk factors for NCDs was used in the study and frequency and proportions were used to analyse the data. A total of 400 subjects, 100 subjects in each group were included in the study. Out of these subjects about 65% of the urban group and 42% of the rural group subjects were aware of the NCDs and their risk factors. Least awareness was observed among the rural subjects without any NCDs (35%). The awareness of risk factors of NCDs and knowledge regarding prevention of NCDs was not satisfactory. The results highlighted the need and scope for health education and interventions to improve the awareness about NCDs and their risk factors.

Although the risk and related factors of hyperkalemia developed in the hospital are known in elderly, risk and related factors of community-acquired hyperkalemia (CAH) in this population are not well known. This study was performed to investigate the risk of CAH in elderly and evaluate the related factors and clinical outcomes. Study design, setting and participants, intervention: Patients (aged ≥65 years) with hyperkalemia were screened. Group 1 (young-old); 65-74 years/old, Group 2 (middle-old); 75-84 years/old, Group 3 (oldest-old); ≥85 years/old, and Group 4 (control group); ≥65 years/old (normal serum potassium levels). The relation between CAH and hospital expenses (HE), the number of comorbid diseases (NCD), and all-cause of mortality rates (MR) were evaluated. We also investigated whether drugs, sex, and NCD are risk factors for the development of CAH. There was a positive correlation between serum potassium levels and length of hospital stay, MR, HE, and NCD (p < 0.001). Risk factors for CAH were the use of non-steroidal-anti inflammatory drugs (NSAIDs) (Odds Ratio [OR]: 2.679), spironolactone (OR: 2.530), and angiotensin converting enzyme inhibitors (ACEI) (OR: 2.242), angiotensin receptor blockers (ARB) (OR: 2.679), ≥2 comorbid diseases (OR: 2.221), female gender (OR: 2.112), and renal injury (OR: 5.55). CAH risk was found to be increased 30.03 times when any of ACEI, ARB, NSAIDs, or spironolactone is given to a patient with a renal injury. Use of NSAIDs, ACEI, ARB, spironolactone and increased NCD are all independent risk factors for CAH in the elderly, especially in patients with kidney diseases.

Context: Coronary heart disease (CHD) is the leading cause of death in the United States. Objective: This study compares differences in risk factors for CHD in diabetic vs. nondiabetic Strong Heart Study participants. Design: This was an observational study. Setting: The study was conducted at three centers in Arizona, Oklahoma, and North and South Dakota. Participants: Data were obtained from 3563 of 4549 American Indians free of cardiovascular disease at baseline. Intervention(s): CHD events were ascertained during follow-up. Main Outcome Measure: CHD events were classified using standardized criteria. Results: In diabetic and nondiabetic participants, 545 and 216 CHD events, respectively, were ascertained during follow-up (21,194 and 22,990 person-years); age- and sex-adjusted incidence rates of CHD were higher for the diabetic group (27.5 vs. 12.1 per 1,000 person-years). Risk factors for incident CHD common to both groups included older age, male sex, prehypertension or hypertension, and elevated low-density lipoprotein cholesterol. Risk factors specific to the diabetic group were lower high-density lipoprotein cholesterol, current smoking, macroalbuminuria, lower estimated glomerular filtration rate, use of diabetes medication, and longer duration of diabetes. Higher body mass index was a risk factor only for the nondiabetic group. The association of male sex and CHD was greater in those without diabetes than in those with diabetes. Conclusions: In addition to higher incidence rates of CHD events in persons with diabetes compared with those without, the two groups differed in CHD risk factors. These differences must be recognized in estimating CHD risk and managing risk factors. PMID:22802089

The aim of this study was to investigate correlates of fibrinogen concentration in black South Africans, as well as its association with cardiovascular disease (CVD) risk and whether urbanisation influences this association. A total of 1,006 rural and 1,004 urban black South Africans from the PURE study were cross-sectionally analysed. The association of fibrinogen with CVD risk was determined by investigating the association of fibrinogen with other CVD risk markers as well as with predicted CVD risk using the Reynolds Risk score. The rural group had a significantly higher fibrinogen concentration than the urban group, despite higher levels of risk factors and increased predicted CVD risk in the urban group. Increased levels of CVD risk factors were, however, still associated with increased fibrinogen concentration. Fibrinogen correlated significantly, but weakly, with overall predicted CVD risk. This correlation was stronger in the urban than in the rural group. Multiple regression analysis showed that a smaller percentage of the variance in fibrinogen is explained by the traditional CVD risk factors in the rural than in the urban group. In conclusion, fibrinogen is weakly associated with CVD risk (predicted overall risk as well with individual risk factors) in black South Africans, and is related to the degree of urbanisation. Increased fibrinogen concentration, in black South Africans, especially in rural areas, is largely unexplained, and likely not strongly correlated with traditional CVD-related lifestyle and pathophysiological processes. This does, however, not exclude the possibility that once increased, the fibrinogen concentration contributes to future development of CVD.

Infection is a major complication in pediatric patients with acute lymphoblastic leukemia during chemotherapy. In this study, the infection characteristics were determined and risk factors analyzed based on the Taiwan Pediatric Oncology Group (TPOG) acute lymphoblastic leukemia (ALL) protocol. We retrospectively reviewed fever events during chemotherapy in 252 patients treated during two consecutive clinical trials at a single institution between 1997 and 2012. Patients were classified as standard, high, and very high risk by treatment regimen according to the TPOG definitions. We analyzed the characteristics and risk factors for infection. Fever occurred in 219 patients (86.9%) with a mean of 2.74 episodes per person. The fever events comprised 64% febrile neutropenia, 39% clinically documented infections, and 44% microbiologically documented infections. The microbiologically documented infections were mostly noted during the induction phase and increased in very high risk patients (89 vs. 24% and 46% in standard-risk and high-risk patients, respectively). Younger age and higher risk (high-risk and very high risk groups) were risk factors for fever and microbiologic and bloodstream infections. Female gender and obesity were additive risk factors for urinary tract infection (odds ratios = 3.52 and 3.24, P < 0.001 and P = 0.004, respectively). Infections developed primarily during the induction phase, for which younger age and higher risk by treatment regimen were risk factors. Female gender and obesity were additive risk factors for urinary tract infection. © 2017 Wiley Periodicals, Inc.

This study is an evaluation of a psychosocial intervention involving child and adolescent survivors of the 2008 Sichuan China earthquake. Sociodemographics, earthquake-related risk exposure, resilience using the Connor-Davidson Resilience Scale, and posttraumatic stress disorder (PTSD) using the UCLA-PTSD Index were collected from 1,988 intervention participants and 2,132 controls. Mean resilience scores and the odds of PTSD did not vary between groups. The independent factors for risk and resilience and the dependent variable, PTSD, in the measurement models between control and intervention groups were equivalent. The structural model of risk and 2 resilience factors on PTSD was examined and found to be unequivalent between groups. In contrast to controls, risk exposure (B = −0.32, p <.001) in the intervention group was negatively associated with PTSD. Rational thinking (B = −0.48, p < .001), a resilience factor, was more negatively associated with PTSD in the intervention group. The second resilience factor explored, self-awareness, was positively associated with PTSD in both groups (B = 0.46 for controls, p < .001, and B = 0.69 for intervention, p < .001). Results highlight the need for more cross-cultural research in resilience theory to develop culturally appropriate interventions and evaluation measures.

The incidence of well-differentiated low-risk thyroid cancer have increased globally over the last three decades. Thyroid cancer treatment relates to a suitable surgical procedure and the use of adjuvant radio-iodine therapy in selected patients. Evaluation of prognostic factors and risk stratification are critical for determining appropriate treatment. Survival of patients with low-risk thyroid cancer is excellent. Appropriate choice of medical treatment resulted in full recovery in most patients. Relapse risk increases with the size of the primary tumor, along with the findings of the risk factors in men. Our study included a total of 1 980 patients in whom were diagnosed T1a and T1b tumors between the years 2003 to 2012. The population included 1 675 women (84.6 %) of average age of 45.22 years and 305 men (15.4 %) of average age of 50.0 years. The bulk of the file represented papillary carcinomas (1 868; 94.4 %), and smaller group of follicular carcinomas (112; 5.6 %). Patients were divided into four groups according to tumor size. Patients were evaluated according to risk factors: unifocality no other risk factors, multifocality - more bearings in thyroid tumor, metastases in regional lymph nodes, distant metastases or combination of risk factors. Group A: In the monitored set of 678 patients with papillary and follicular microcarcinoma up to 5 mm, during histological input, the findings revealed one bearing (unifocal type of cancer) in 566 patients. Multifocality was found in 112 patients, local nodal metastasis were demonstrated in 24 cases and pulmonary metastasis was discove-red in 1 case. Group B: In this group there were 576 study patients with papillary and follicular microcarcinoma size of 5-10 mm. Histological findings were captured input one bearing carcinoma in 434 patients, 142 patients with multifocality, in 53 cases of local nodal metastasis, and 1 case of bone metastases. Group C: In this group there were 467 study patients with papillary and follicular microcarcinoma size 10-15 mm. The histological initial finding captured unifocal type of cancer in 344 patients, multifocality in 123 patients, in 45 cases local metastases and in 3 cases of pulmonary metastases. Group D: 259 patients were monitored in this group with breast size 16-20 mm. At the initial finding was captured one bearing cancer in 188 patients, multifocality in 71 patients, in 24 cases evidence of local metastases and 2 patients had a case of distant lung metastases. In patients in whom risk factors were found, radioiodine treatment was indicated. This included 744 patients. In this group of patients after a year or more, relapse was observed in 74 patients (9.94 %). In 1 236 patients who did not undergo radioiodine treatment, there was a relapse in 49 patients (3.96 %). Based on our analysis, it is necessary to stratify the risk of relapse according to risk factors. In case of missed radioiodine therapy in patients with low-risk cancer without confirmed risk factors, it is also necessary to have regular clinical, laboratory and ultrasound examination. It is important to distinguish patients with risk factors that may contribute to disease recurrence. Only in this way, on one hand we prevent excessive treatment of patients with low-risk thyroid cancer which leads to increased cost of health care, and on the other hand prevent reduced level of care for patients with an increase in relapses.

It is inconclusive that periodontitis is an independent risk factor for adverse pregnancy outcomes. This study aims to investigate the association between maternal periodontitis and preterm and/or low birth weight babies. This was a prospective cross-sectional study. After prior informed consent, 3500 postpartum mothers were selected from various hospitals in Tamil Nadu and categorized into the following groups: group-1 - Normal term normal birth weight ( n = 1100); Group-2 - Preterm normal birth weight ( n = 400); Group-3 - preterm low birth weight (PTLBW) ( n = 1000); and Group-4 - Normal term low birth weight ( n = 1000). Periodontal examination was done, and risk factors were ascertained by means of questionnaire and medical records. Comparison between case groups and control groups were done, odds ratio (OR) was calculated, and statistical significance were assessed by Chi-square tests. To control for the possible confounders, all variables with P < 0.05 were selected and entered into multivariate regression model, and OR and 95% confidence limits were again estimated. SPSS-15 software was used. Periodontitis was diagnosed in 54.8%, 52.3%, 53.8%, 59.4%, respectively. On comparison between the groups, none of periodontal parameters showed significant association except for the crude association observed in Group-4 for mild periodontitis (OR - 1.561; P = 0.000) and PTLBW. Periodontitis is not a significant independent risk factor, and obstetric factors contribute a major risk for preterm and/or low birth weight babies.

This study examined whether assigning running shoes based on the shape of the bottom of the foot (plantar surface) influenced injury risk in Air Force Basic Military Training (BMT) and examined risk factors for injury in BMT. Data were collected from BMT recruits during 2007; analysis took place during 2008. After foot examinations, recruits were randomly consigned to either an experimental group (E, n=1042 men, 375 women) or a control group (C, n=913 men, 346 women). Experimental group recruits were assigned motion control, stability, or cushioned shoes for plantar shapes indicative of low, medium, or high arches, respectively. Control group recruits received a stability shoe regardless of plantar shape. Injuries during BMT were determined from outpatient visits provided from the Defense Medical Surveillance System. Other injury risk factors (fitness, smoking, physical activity, prior injury, menstrual history, and demographics) were obtained from a questionnaire, existing databases, or BMT units. Multivariate Cox regression controlling for other risk factors showed little difference in injury risk between the groups among men (hazard ratio [E/C]=1.11, 95% CI=0.89-1.38) or women (hazard ratio [E/C]=1.20, 95% CI= 0.90-1.60). Independent injury risk factors among both men and women included low aerobic fitness and cigarette smoking. This prospective study demonstrated that assigning running shoes based on the shape of the plantar surface had little influence on injury risk in BMT even after controlling for other injury risk factors.

Abstract Background The purpose of this study was to analyse the prevalence of postmenopausal osteoporosis risk factors and to analyse the T-score variability in spine and hip according to the associated risk factors. Methods This is a retrospective study (2003-2007) including 177 female patients with postmenopausal osteoporosis. The patients were separated in seven groups according to the number of risk factors per case. The T-score was compared between this groups using unpaired t-Student test. Results The most frequent risk factor was early menopause (44.63%), followed by low consumption of dairy products (37.29%), coffee consumption (25.99%), sedentary lifestyle (20.9%), smoking (19.21%), delayed menarche (15.25%), low body mass index (10.71%), nulliparity (7.91%), alcohol consumption (0.56%). The maximum number of risk factors per case was six. The T-score decreased with increasing number of risk factors. T-score differences are statistically significant when comparing cases with 6 risk factors to cases with 5 risk factors (P=0.0315 in spine; P=0.0088 in hip), 4 risk factors (P=0.0076 in spine; P=0.043 in hip), 3 risk factors (P<0.0001 in spine; P=0.0205 in hip), 2 risk factors (P=0.0012 in spine; P<0.0001 in hip), a single risk factor (P<0.001 in spine and hip) and no risk factor (P=0.0075 in spine; P=0.0006 in hip). Conclusion Association of several risk factors leads to decrease of T-score so being able to avoid any such factors may contribute to a better bone mineral density. This could be achieved by the education of female population regarding postmenopausal osteoporosis risk factors, followed by adopting an appropriate lifestyle and diet. PMID:26060640

Several risk factors seem to play a role in the development of osteoporosis. Phytate is a naturally occurring compound that is ingested in significant amounts by those with diets rich in whole grains. The aim of this study was to evaluate phytate consumption as a risk factor in osteoporosis. In a first group of 1,473 volunteer subjects, bone mineral density was determined by means of dual radiological absorptiometry in the calcaneus. In a second group of 433 subjects (used for validation of results obtained for the first group), bone mineral density was determined in the lumbar column and the neck of the femur. Subjects were individually interviewed about selected osteoporosis risk factors. Dietary information related to phytate consumption was acquired by questionnaires conducted on two different occasions, the second between 2 and 3 months after performing the first one. One-way analysis of variance or Student's t test was used to determine statistical differences between groups. Bone mineral density increased with increasing phytate consumption. Multivariate linear regression analysis indicated that body weight and low phytate consumption were the risk factors with greatest influence on bone mineral density. Phytate consumption had a protective effect against osteoporosis, suggesting that low phytate consumption should be considered an osteoporosis risk factor.

The National Health and Nutrition Examination Survey (NHANES) 2003-2004 data set was utilized to examine and compare trends and differences in PAD-related risk factor variables among 5 different ethnic/racial groups. The sample included individuals 40 years and older with PAD and of the ethnic/racial groups: Mexican American, Other Hispanic, Non-Hispanic White, Non-Hispanic Black, and Other/Multiracial. Two demographic variables (age and gender) and 4 PAD-risk factors (hypertension [HTN], systolic blood pressure [SBP], and diastolic blood pressure [DBP]), dyslipidemia, high-density lipoprotein [HDL] and low-density lipoprotein [LDL], diabetes, and cigarette smoking) were examined for each group. The study design conducted was descriptive using the NHANES 2003-2004 secondary data set. Raw data were weighted. Descriptive statistics were measured, Chi-squares were compared, and Phi-coefficients were measured for association using SAS version 9.1 and SUDAAN 10.0. The group with the highest prevalence of PAD are females 40-50 years of age, and the ethnic group with PAD who have the highest risk for PAD-related risk factors are Non-Hispanic Black. Through Chi-square significant differences (P=0.00001-0.03874) between specific ethnic groups for all four PAD-related risk factors (i.e., HTN, dyslipidemia, diabetes and cigarette smoking). All of the associations between the prevalence of HTN, dyslipidemia, diabetes, or cigarette smoking and ethnicity were statistically significant (P=<0.0001). Overall differences exist among the different ethnic groups. Copyright © 2012 Society for Vascular Nursing, Inc. Published by Mosby, Inc. All rights reserved.

Objectives To investigate whether bicycling to school improves cardiometabolic risk factor profile and cardiorespiratory fitness among children. Design Prospective, blinded, randomised controlled trial. Setting Single centre study in Odense, Denmark Participants 43 children previously not bicycling to school were randomly allocated to control group (n=20) (ie, no change in lifestyle) or intervention group (ie, bicycling to school) (n=23). Primary and secondary outcome measures Change in cardiometabolic risk factor score and change in cardiorespiratory fitness. Results All participants measured at baseline returned at follow-up. Based upon intention-to-treat (ITT) analyses, clustering of cardiometabolic risk factors was lowered by 0.58 SD (95% CI −1.03 to −0.14, p=0.012) in the bicycling group compared to the control group. Cardiorespiratory fitness (l O2/min) per se did not increase significantly more in the intervention than in the control group (β=0.0337, 95% CI −0.06 to 0.12, p=0.458). Conclusions Bicycling to school counteracted a clustering of cardiometabolic risk factors and should thus be recognised as potential prevention of type 2 diabetes mellitus and cardiovascular disease (CVD). The intervention did, however, not elicit a larger increase in cardiorespiratory fitness in the intervention group as compared with the control group.

Thirty-one abdominal fascial wound dehiscences occurred in 2,761 patients undergoing major abdominal surgery during a 5-year period (1%). Twenty-two specific local and systemic risk factors were analyzed and compared with the risk factors of a control group of 38 patients undergoing similar procedures without dehiscence. Through multivariate analysis, each factor was assessed as an independent statistical variable. Significant factors (p less than 0.05) were found to include age over 65, wound infection, pulmonary disease, hemodynamic instability, and ostomies in the incision. Additional systemic risk factors that were found to be significant included hypoproteinemia, systemic infection, obesity, uremia, hyperalimentation, malignancy, ascites, steroid use, and hypertension. Risk factors not found to be important independent variables included sex, type of incision, type of closure, foreign body in the wound, anemia, jaundice, and diabetes. When dehiscence and control groups were combined, 30% of patients with at least five significant risk factors developed dehiscence, and all the patients with more than eight risk factors developed a wound dehiscence. There was an overall mortality of 29%, which was directly related to the number of significant risk factors. The co-existence of 9 risk factors portended death in one third of the patients, and all the patients with more than 10 risk factors died.

Context Although numerous risk factors have been established to predict the development of acute coronary syndrome (ACS), the risk factor profile may be different between the younger and older individuals. Aim To analyse the frequency and pattern of atherogenic risk factors and angiographic profiles in age-stratified Gujarati patients with ACS. Materials and Methods ACS patients undergoing coronary angiography at U.N. Mehta Institute of Cardiology and Research, Gujarat, India between January 2008 and December 2012 were classified in to two age groups with 40y as cut-off. Patients were assessed for conventional risk factors (diabetes mellitus, dyslipidaemia, hypertension, smoking, obesity), novel risk factors (high sensitivity C-reactive protein, lipoprotein (a), homocysteine), and angiographic profiles.The statistical difference between two age groups was determined by Student’s t-test for continuous variables and Chi-square or Fisher’s exact test for categorical variables. Results A total of 200 patients, 100 patients ≤40 y of age and 100 patients >40 y of age, were evaluated. Older patients had higher frequency of hypertension (32 vs. 16%, p=0.008), while family history of coronary artery disease was more common among younger patients (19 vs. 9%, p=0.041). The incidence of diabetes, dyslipidaemia, smoking and tobacco chewing did not vary significantly between the two groups. Total cholesterol and low-density lipoprotein cholesterol levels were significantly higher in the younger group (p<0.05). Lipoprotein (a), homocysteine and high-sensitivity C reactive protein levels were comparable between two age groups. Multi-vessel coronary artery disease was more common among older group. The most commonly affected coronary artery was the left anterior descending artery among younger patients (44%) and the left circumflex artery among older patients (38.1%). Conclusion Young patients with ACS had different atherosclerotic risk profile and less extensive coronary artery disease as compared to older counterparts. Emphasis should be given on diagnosis and management of major modifiable risk factors. PMID:26266146

The aim of this study was to assess the metabolic characteristics and risks of stone recurrence in young adult stone patients in Korea. The medical records of 1532 patients presenting with renal or ureteric stones at our stone clinic between 1994 and 2015 were retrospectively reviewed. Patients were grouped according to age (young adult, 18-29 years; intermediate onset, 30-59 years; old age, ≥60 years) at first presentation, and measurements of clinicometabolic characteristics and risks of stone recurrence were compared. Overall, excretion of urinary stone-forming substances was highest in the intermediate onset group, followed by the young adult and old age groups. Importantly, excretion of urinary citrate was lowest in the young adult group. Kaplan-Meier analyses identified a significant difference between the three age groups in terms of stone recurrence (log rank test, p < 0.001). Multivariate Cox regression analyses revealed that age at first stone presentation was an independent risk factor for stone recurrence. Urinary citrate excretion was an independent risk factor for stone recurrence in young adult stone patients. Younger age (18-29 years) at first stone presentation was a significant risk factor for stone recurrence, and urinary citrate excretion was an independent risk factor affecting recurrence in this group. Metabolic evaluation and potassium citrate therapy should be considered for young adult stone patients to prevent recurrence.

To investigate the prevalence rate of nutritional risk in high-risk stroke groups in community, analyze its influencing factors, and analyze and compare the relationship between nutritional risk or malnutrition assessed by different nutritional evaluation methods and cognitive function, so as to provide the basis and guidance for clinical nutritional assessment and support. A cross-sectional survey was performed for 1196 cases in high-risk stroke groups in community from December 2015 to January 2017. At the same time, the nutritional status of patients was evaluated using the mini nutritional assessment (MNA) and MNA-short form (MNA-SF), and the cognitive status of patients was evaluated using the mini-mental state examination (MMSE). Moreover, the relevant influencing factors of nutritional risk and MMSE score were analyzed and compared. High-risk stroke groups in community suffered from a high risk of malnutrition. MNA-SF had a higher specificity and lower false positive rate than MNA. Nutritional risk occurred more easily in high-risk stroke groups in community with a history of diabetes mellitus, less physical exercise or light manual labor, daily use of multiple drugs, and higher age. Those with a higher nutritional risk were more prone to cognitive impairment. High-risk stroke groups in community, complicated with hyperhomocysteinemia, daily use of three or more kinds of prescription drugs, and a previous history of stroke, were accompanied by cognitive impairment easily. MNA-SF can be used for the nutritional screening of high-risk stroke groups in community. For the high-risk stroke groups in community, the rational nutritional diet should be publicized, blood sugar should be controlled in a scientific manner and physical exercise should be moderately increased.

Background Research is needed to identify early life risk factors associated with different developmental paths leading to overweight by adolescence. Objectives To model heterogeneity in overweight development during middle childhood and identify factors associated with differing overweight trajectories. Methods Data was drawn from the Quebec Longitudinal Study of Child Development (QLSCD; 1998-2010). Trained research assistants measured height and weight according to a standardized protocol and conducted yearly home interviews with the child’s caregiver (mother in 98% of cases). Information on several putative early life risk factors for the development of overweight were obtained, including factors related to the child’s perinatal, early behavioral family and social environment. Group-based trajectories of the probability of overweight (6-12 years) were identified with a semiparametric method (n=1678). Logistic regression analyses were used to identify early risk factors (5 months- 5 years) associated with each trajectory. Results Three trajectories of overweight were identified: “early-onset overweight” (11.0 %), “late-onset overweight” (16.6%) and “never overweight” (72.5%). Multinomial analyses indicated that children in the early and late-onset group, compared to the never overweight group, had 3 common types of risk factors: parental overweight, preschool overweight history, and large size for gestational age. Maternal overprotection (OR= 1.12, CI: 1.01-1.25), short nighttime sleep duration (OR=1.66, CI: 1.07-2.57), and immigrant status (OR=2.01, CI: 1.05-3.84) were factors specific to the early-onset group. Finally, family food insufficiency (OR=1.81, CI: 1.00-3.28) was weakly associated with membership in the late-onset trajectory group. Conclusions The development of overweight in childhood follows two different trajectories, which have common and distinct risk factors that could be the target of early preventive interventions.

The aim of this work is to identify the most significant risk factors for hearing impairment in high risk neonates hospitalized at our Neonatal Intensive Care Unit (NICU) and to assess the sensitivity of hearing screening tests. This study involved 260 neonates admitted to a tertiary NICU; they were classified into two groups; 150 preterm and 110 full terms with risk factors for hearing loss. The hearing screening tests performed were transient evoked otoacoustic emissions (TEOAEs) and the automated auditory brainstem response (AABR). Forty-eight preterm neonates (32%) and 30 full term neonates (27.3%) had pathological AABR. In preterm group, mechanical ventilation more than five days, sepsis, usage of aminoglycosides, loop diuretics, vancomycin alone or in combination with aminoglycosides and prolonged duration of admission were considered risk factors of hearing affection whereas in full term group mechanical ventilation more than five days was the risk factor of hearing affection (p<.05). The prevalence of hearing loss is highest among high risk neonates and TEOAE and AABR were found to be reliable screening tools. Use of ototoxic drugs and mechanical ventilation for more than five days were significant risk factors for hearing loss in our study population.

Context: Hypertension in youth is increasing, but there is a dearth of data about the knowledge of risk factors in this age group. Aims: To assess the knowledge of risk factors of hypertension among university students and associate it with the blood pressure, physical activity, family history of cardiovascular disease (CVD), and sociodemographic variables. Materials and Methods: A cross-sectional survey among students enrolled in the first year, in the four academic programs, with the use of a validated, self-administered questionnaire on physical activity in the past 30 days and knowledge of risk factors of hypertension. A score of 6 on 11 was considered as good knowledge for modifiable risk factors. Blood pressure was also measured. The data was analyzed using PASW-17, Chi square test, and binary logistic regression analysis was done. Results: Of the 110 participants, 69.2% were < 20 years of age, 76.4% were females, and 40% were Arabs. Stress, high cholesterol, obesity, and smoking were identified as risk factors by 75.5, 73.6, 77.6, and 71.8%, respectively; 69.1% considered high salt intake and 62.7% considered high calorie diet as risk factors. Energy drink was considered as a risk factor by 64.5%, coffee consumption 35.5%, physical inactivity 47%, and oral contraceptives 13.6%. Half the group did not consider a family history of CVD as a risk factor, 60% did not consider older age as a risk factor, and 88% did not think male gender was a risk factor. Knowledge of modifiable risk factors was better than that of non-modifiable risk factors. Although nationality, course of study, raised blood pressure, and history of diabetes showed significant association with good knowledge, their net effect was not significant by the Adjusted Odd's Ratio. Conclusions: The study identified some gaps in knowledge regarding both modifiable and non-modifiable risk factors of hypertension among students. A larger study would enable health promotion activities tailored to the needs of this age group. PMID:22175039

Considering the program of screening for risk factors of stroke in Eastern China, the aim of this study was to compare the distribution differences in risk factors for stroke among the high-risk population living in urban and rural areas. A total of 231,289 residents were screened and basic information collected. Risk factors for stroke among the high-risk population were compared between the urban and rural groups. A total of 117,776 high-risk residents from urban areas and 113,513 from rural areas were included in the analysis. The prevalence of hypertension was much higher in rural areas (73.3%) than that in urban areas (64.1%). Dyslipidemia (48.9% vs. 26.9%), sport lack (46.6% vs. 31.6%), diabetes mellitus (21.3% vs. 16.5%), and atrial fibrillation (18.7% vs. 9.8%) were more prevalent in the urban group, while smoking (26.5% vs. 28.8%), previous stroke (10.1% vs. 16.9%), and transient ischemic attack (20.9% vs. 24.6%) were less prevalent. Among the population at high risk of stroke, there were significant differences in the distribution of the following risk factors between the urban and rural groups: hypertension, atrial fibrillation, dyslipidemia, lack of physical exercise, and a previous stroke.

Non-communicable disease (NCD) risk factors can co-exist with disability and cause a greater burden on the health status of adults with disabilities. A lack of egalitarian social policies in China may result in gender disparities in the NCD risk factors of adults with disabilities. However, little is known about the gender disparities in the association between socio-demographics and NCD risk factors among adults with disabilities in China; consequently, we examined this association among adults with disabilities in Shanghai, China. We used the health examination data of 44,896 adults with disabilities in Shanghai in 2014. Descriptive analyses and logistic regression models were conducted to estimate gender disparities in the association between socio-demographics, disability characteristics, and four selected NCD risk factors among adults with disabilities-including high blood pressure, high blood glucose, high blood lipids, and being overweight. We estimated marginal effects (MEs) on NCD risk factors between gender and other confounders. Women with disabilities were about 11.6 percentage points more likely to suffer from high blood lipids and less likely to develop the other three risk factors than men were. The association of age group, residence permit, education level, marital status, and disability type with health outcomes varied by gender among adults with disabilities. The difference in age effects between men and women was more pronounced in older age groups. Urban residence was associated with less risk of high blood pressure risk among women (Δ ME  =  - 0.035, p  < 0.01), but no significant difference in other NCD risk factors. Education remained a major protective factor against high blood pressure, high blood glucose and being overweight among women with disabilities ( MEs  < 0, p  < 0.05); however, this did not hold for men. The difference in marriage effects between men and women was observed in high blood lipids (Δ ME  =  - 0.048 for the married group and -0.054 for the divorced or widowed group) and overweight individuals (Δ ME  =  - 0.091 for the married group and -0.114 for the divorced or widowed group). Women with intellectual disabilities or mental disabilities reported worse health conditions than men did. Preventive strategies and interventions on NCD risk factors for adults with disabilities should take into account gender disparities in these socio-demographic effects. Rural women or poorly educated women with disabilities can be a vulnerable population that requires more health education and promotion strategies. Health education for caregivers of women with intellectual or mental disabilities may also play a vital role in preventing their NCD risk factors.

Women delivering singletons after in vitro fertilization (IVF) procedures have a greater risk of preterm delivery (PD). The aim of our study was to analyze PD risk factors and to identify those that could possibly be prevented. In our matched controlled study we analyzed 1127 singleton deliveries after IVF and transfer of fresh embryos performed at the University Medical Center Ljubljana between 1 January 2002 and 31 December 2010. For every delivery included in the study group we chose three consecutive controls matched by maternal age, parity and maternity hospital. The main outcome measure was PD (<37 weeks). Investigated variables were: previous PD (PPD), conization, pregestational diabetes mellitus, uterine anomaly, operation on the uterus, chronic renal disease, maternal age and parity, and body mass index (BMI). Variables investigated within the IVF group were: stimulation protocol, laboratory procedure, number of retrieved oocytes and number and quality of transferred embryos. The PD rate after IVF was 1.5 times higher than after natural conception (11.5% in the IVF group and 7.7% in the control group, p<0.001). Conization and chronic renal disease were shown to be significant risk factors for PD in both the IVF group and the naturally conceiving controls. BMI>30 was an important risk factor only in the IVF group (OR 1.86 (1.06-3.27) vs. 1.10 (0.67-1.80)) and PPD only in the controls (OR 1.83 (0.78-4.28) vs. 3.22 (1.55-6.67)). Among the investigated PD risk factors, an IVF procedure was shown to be the fifth most important one. On analyzing parameters of the ovarian stimulation and IVF procedure, no PD risk factor was identified. IVF was shown to be a significant risk factor for PD. In the IVF population, BMI plays a far more important role in PD than in the fertile population. In our research PD reoccurrence in IVF group was less than expected, which could perhaps be explained by the surgical correction of gynecological pathology and, where necessary, its being combined with cerclage. The investigation of parameters related to the IVF procedure did not identify any risk factors for PD. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Background and Purpose Achilles tendinopathy can be a debilitating chronic condition for both active and inactive individuals. The identification of risk facors is important both in preventing but also treating tendinopathy, many factors have been proposed but there is a lack of primary epidemiological data. The purpose of this study was to develop a statement of expert consensus on risk factors for Achilles tendinopathy in active and sedentary patient populations to inform a primary epidemiological study. Study design Delphi study Methods and Measures An online Delphi study was completed inviting participation from world tendon experts. The consensus was developed using three rounds of the Delphi technique. The first round developed a complete list of potential risk factors, the second round refined this list but also separated the factors into two population groups – active/athletic and inactive/sedentary. The third round ranked this list in order of perceived importance. Results Forty-four experts were invited to participate, 16 participated in the first round (response rate 40%) and two dropped out in the second round (resulting in a response rate of 35%). A total of 27 intrinsic and eight extrinsic risk factors were identified during round one. During round two only 12 intrinsic and five extrinsic risk factors were identified as important in active/athletic tendinopathy while 14 intrinsic and three extrinsic factors were identified as important for inactive/sedentary tendinopathy. Conclusions Risk factors for Achilles tendinopathy were identified based on expert consensus, and these factors provide a basis for primary epidemiological studies. Plantarflexor strength was identified as the primary modifiable factor in the active/athletic group while systemic factors were identified as important in the inactive/sedentary group, many of the potential factors suggested for either group were non-modifiable. Non-modifiable factors include: previous tendinopathy, previous injury, advancing age, sex, steroid exposure, and antibiotic treatment. Level of evidence Level V PMID:27757281

This study aimed to describe and to analyse the importance of educational level for controlled risk factors and health-related quality of life (HRQoL). This observational study was conducted in nine European countries (5632 patients in 249 practices). We compared patients with a low level of education (up to 9 years) with patients with a high level of education (>9 years), with regard to controlled cardiovascular disease risk factors and HRQoL. A multilevel approach was used for statistical analysis. Patients with a low level of education were older (P < 0.001), more often female (P < 0.001), more often single (P < 0.001) and had a higher number of other conditions (e.g. heart failure) (P < 0.001). Significant differences in terms of controlled risk factors were revealed for blood pressure (RR) ≤ 140/90 mmHg (P = 0.039) and the sum of controlled risk factors (P = 0.027). Higher age, lower education, female gender, living as single, patient group (coronary heart disease patients) and the number of other conditions were negatively associated with HRQoL. A higher sum of controlled risk factors were positively associated with higher HRQoL in the whole sample (r = 0.0086, P < 0.001) as well as in both educational-level groups (r = 0.0075, P = 0.038 in the low-level group and r = 0.0082, P = 0.001 in the high-level group). Patients with a lower educational level were more often females, singles, had a higher number of other conditions, a higher number of uncontrolled risk factors and a lower HRQoL. However, the higher the control of risk factors was, the higher the HRQoL was overall as well as in both educational-level groups. © The Author 2013.

The aims of the present study were: (1) to evaluate the compliance with guidelines and (2) to identify risk factors of non-compliance. Samples for ABO group determination collected between January 1st and December 15th, 2013 in the University hospital of Nîmes, France were analyzed. An ABO group determination demand was considered non-compliant if more than one tube arrived in the laboratory within ten minutes apart. Between May 1st and June 30th 2014, a self-administered questionnaire was offered to the nurses of the hospital on a random day for each service during this period. The aim was to validate the non-compliance criterion and the identification of risk factors using logistic regression. Among the 16,450 analyzed blood samples, the overall compliance rate was 65.1%. Lower compliance rates were found in the surgical services. Independent risk factors for wrong practice were work overload, surgical service and individual intermediate transfusion frequency. More than one third of ABO group determinations did not follow national recommendations, which induces a substantial risk of "wrong blood in tube" and group error. The study revealed major variations among hospital services. Identification of risk factors allows targeted corrective actions. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

The origin of testicular germ cell cancer (TGCC) is believed to be carcinoma in situ cells developed in utero. Clinically, TGCCs are divided into two major histological groups, seminomas and non-seminomas, where the latter group includes non-seminomatous TGCCs with seminomatous components (mixed S/NS TGCC). Recent studies, however, have suggested that non-seminomas and mixed S/NS TGCCs could have certain differences in aetiology, and in this study the TGCCs were divided into three, rather than the conventional two histological groups. A large case-control study was undertaken on data on all live-born boys registered in the Medical Birth Registry of Norway during the period 1967-1998 (n=961 396). Among these were 1087 TGCC cases registered in the Cancer Registry of Norway until February 2004. We found several risk factors for TGCC, including low parity, low gestational age, epilepsy and retained placenta. Several of the variables studied seemed to be risk factors for specific histological groups, e.g. parity 0 vs. 2 and low gestational age being associated with increased risk of non-seminomas, but not of mixed S/NS TGCC, and low maternal age being associated with increased risk of mixed S/NS TGCC, but not of non-seminomatous TGCC. Therefore, our results might suggest that non-seminomas and mixed S/NS TGCCs have partially different risk factors, whose associations may be obscured by combining these two histological groups. The histological groups were not significantly different, however. Most of our findings on risk factors for TGCC are in agreement with at least some previous studies. An unexplainable exception is low birth weight being associated with reduced risk of TGCC in our study.

To study the effect of a universal prevention intervention targeting cannabis use in individual children with different risk profiles. A school-based randomized controlled prevention trial was conducted over a period of 33 months (n=1874 sixth-graders, baseline mean age 11.82). We used a two-level random intercept logistic model for panel data to predict the probabilities of cannabis use for each child. Specifically, we used eight risk/protective factors to characterize each child and then predicted two probabilities of cannabis use for each child if the child had the intervention or not. Using the two probabilities, we calculated the absolute and relative effect of the intervention for each child. According to the two probabilities, we also divided the sample into a low-risk group (the quarter of the children with the lowest probabilities), a moderate-risk group, and a high-risk group (the quarter of the children with the highest probabilities) and showed the average effect of the intervention on these groups. The differences between the intervention group and the control group were statistically significant in each risk group. The average predicted probabilities of cannabis use for a child from the low-risk group were 4.3% if the child had the intervention and 6.53% if no intervention was provided. The corresponding probabilities for a child from the moderate-risk group were 10.91% and 15.34% and for a child from the high-risk group 25.51% and 32.61%. School grades, thoughts of hurting oneself, and breaking the rules were the three most important factors distinguishing high-risk and low-risk children. We predicted the effect of the intervention on individual children, characterized by their risk/protective factors. The predicted absolute effect and relative effect of any intervention for any selected risk/protective profile of a given child may be utilized in both prevention practice and research.

Factors Influencing Cancer Risk Perception in High Risk Populations: A Systematic Review

PubMed Central

2011-01-01

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 relatively undeveloped in several key topic areas including cancers other than breast and in specific populations. Future rigorous risk perception research using experimental designs and focused on cancers other than breast would advance the field. PMID:21595959

On the association between sexual attraction and adolescent risk behavior involvement: Examining mediation and moderation.

On the basis of a large-scale survey of high-school youth, the authors compared adolescents reporting exclusively heterosexual, mostly heterosexual, bisexual, and predominately same-sex attraction based on high-risk involvement across a range of risk behaviors. Bisexual and same-sex attracted groups were characterized by heightened high-risk involvement relative to the other two groups. Mediation analysis was used to determine whether these group disparities were explained by a set of normative predictive factors spanning multiple life domains. Differences among a combined exclusively/mostly heterosexual attraction group and both the bisexual and same-sex attraction groups were attenuated (66% and 50%, respectively) after incorporating the hypothesized intervening predictive factors, providing evidence of partial mediation. Primary mediators included intrapersonal (attitudes toward risk-taking; academic orientation), interpersonal (peer victimization; parental relationships; unstructured activities), and environmental (substance availability) factors. Mediation results were consistent across participant age and sex. Implications, limitations, and directions for future research are discussed. Copyright (c) 2008 APA.

The prevalence and impact of risk factors for ethnic differences in loneliness

PubMed Central

El Fakiri, Fatima

2016-01-01

Background: Previous studies have demonstrated that loneliness is more frequently present in citizens of ethnic minority groups than in natives. The current study investigates whether ethnic differences in emotional and social loneliness between Moroccan, Turkish, Surinamese and Dutch adults living in the Netherlands are due to ethnic differences in the presence and/or impact of an array of possible risk factors, such as partnership, health and socioeconomic status. Methods: The data were collected in 2012 as a part of a general health questionnaire of the Public Health Services in the four major cities of the Netherlands, containing 20.047 Dutch, 1.043 Moroccan, 1.197 Turkish and 1.900 Surinamese respondents. Results: Structural equation models showed that ethnic differences in emotional and social loneliness can be ascribed to ethnic differences in the prevalence and impact of several risk factors. Main findings were that all three ethnic minority groups reported feeling less healthy and more discriminated against than the Dutch group, which was related to increased loneliness. Perceived financial difficulties and people in the neighbourhood not getting along had more impact on feelings of loneliness for the Turkish group than loneliness for the other ethnic groups. Furthermore, members of the Turkish group were found more at risk to feel anxious or depressed, which was in turn related to increased loneliness. Conclusions: Policy makers are encouraged to develop multifaceted prevention strategies concerning those risk factors that are most changeable, thereby focusing per risk factor on those ethnic groups for which it is an important contribution to loneliness.

Although ethnic or cultural differences affect prevalence of cardiovascular risk factors, limited information is available about the age- and gender-stratified prevalence of the risk factors in Asian stroke population. We assessed gender- and age-stratified prevalences of major risk factors in Korean stroke patients, and assumed that the gender differences are attenuated by adjustment with lifestyle factors. Using the nationwide hospital-based stroke registry, we identified 9417 ischemic stroke patients admitted between April 2008 and January 2011. Prevalence of hypertension, diabetes, hyperlipidemia, atrial fibrillation, prior stroke, and coronary heart disease was assessed in both genders by age groups. We analyzed gender differences of the prevalence among the age groups by calculating prevalence ratio, and further explored the influence of lifestyle factors on the gender difference in multivariable analyses. Hypertension and hyperlipidemia were more common in men until middle age, but after that more common in women, whereas diabetes was more common in women after 65 years of age. Atrial fibrillation increased steadily with age in both genders but was more common in women through all age groups. Prior stroke and coronary heart disease showed inconsistent gender differences. Gender differences in hypertension and diabetes among the age groups were attenuated by adjustment with accompanying risk factors including lifestyle factors. Korean women with stroke had more hypertension and hyperlipidemia after middle age, more diabetes after 65 years, and more atrial fibrillation throughout all ages. Strategies to control risk factors in women at risk for stroke are eagerly needed. © 2013 The Authors. International Journal of Stroke © 2013 World Stroke Organization.

Recent data indicate that fixed-dose combination (FDC) pills, polypills, can produce sizeable risk factor reductions. There are very few published data on the consistency of the effects of a polypill in different patient populations. It is unclear for example whether the effects of the polypill are mainly driven by the individuals with high individual risk factor levels. The aim of the present study is to examine whether baseline risk factor levels modify the effect of polypill treatment on low-density lipoprotein (LDL)-cholesterol, blood pressure (BP), calculated cardiovascular relative risk reduction and adverse events. This paper describes a post-hoc analysis of a randomised, placebo-controlled trial of a polypill (containing aspirin 75 mg, simvastatin 20 mg, lisinopril 10 mg and hydrochlorothiazide 12.5 mg) in 378 individuals without an indication for any component of the polypill, but who had an estimated five-year risk for cardiovascular disease ≥7.5%. The outcomes considered were effect modification by baseline risk factor levels on change in LDL-cholesterol, systolic BP, calculated cardiovascular relative risk reduction and adverse events. The mean LDL-cholesterol in the polypill group was 0.9 mmol/l (95% confidence interval (CI): 0.8-1.0) lower compared with the placebo group during follow-up. Those with a baseline LDL-cholesterol >3.6 mmol/l achieved a greater absolute LDL-cholesterol reduction with the polypill compared with placebo, than patients with an LDL-cholesterol ≤3.6 mmol/l (-1.1 versus -0.6 mmol/l, respectively). The mean systolic BP was 10 mm Hg (95% CI: 8-12) lower in the polypill group. In participants with a baseline systolic BP >135 mm Hg the polypill resulted in a greater absolute systolic BP reduction with the polypill compared with placebo, than participants with a systolic BP ≤ 135 mm Hg (-12 versus -7 mm Hg, respectively). Calculated from individual risk factor reductions, the mean cardiovascular relative risk reduction was 48% (95% CI: 43-52) in the polypill group. Both baseline LDL-cholesterol and estimated cardiovascular risk were significant modifiers of the estimated cardiovascular relative risk reduction caused by the polypill. Adverse events did not appear to be related to baseline risk factor levels or the estimated cardiovascular risk. This study demonstrated that the effect of a cardiovascular polypill on risk factor levels is modified by the level of these risk factors. Groups defined by baseline LDL-cholesterol or systolic BP had large differences in risk factor reductions but only moderate differences in estimated cardiovascular relative risk reduction, suggesting also that patients with mildly increased risk factor levels but an overall raised cardiovascular risk benefit from being treated with a polypill. © The European Society of Cardiology 2016.

To compare clinicopathological features and long-term outcome in gastric cancer patients coming from high-risk and low-risk areas of Italy. Better survival rates have been reported from countries with higher incidence of gastric cancer. Data regarding 829 patients coming from Tuscany (group A) and 143 patients coming from Southern Italy (group B) were analyzed. Mean follow-up time was 56 +/- 57 months; it was 85 +/- 63 months in surviving patients or not tumor-related deaths. Prognostic factors were investigated by multivariate analysis with Cox proportional hazard model after verifying the assumption of proportionality of the risk associated with covariates. Lauren diffuse-mixed histotype, younger age, extended lymphadenectomy, and advanced stages were more common in group B. Gastric cancer-related 10-year survival probability was 48% in group A versus 29% in group B (log-rank test: P < 0.001). By multivariate analysis, geographic area was confirmed as a significant prognostic factor (hazard ratio for group B vs. group A: 1.52, 95% confidence interval: 1.12-2.06, P = 0.006). The influence of this factor on long-term survival was independent from other clinical, surgical, and pathologic factors, and was notable in neoplasms involving the serosa (10-year survival probability: 15% in group A vs. 3% in group B, log-rank test: P = 0.005). Patients coming from low-risk area of Italy showed distinct pathologic features, more advanced stage, and worse prognosis when compared with patients coming from high-risk area. These findings may be indicative of different tumor biology, and may contribute to partly explain worldwide geographic variability in prognosis reported in different series.

There are multiple factors that can affect the risk of tobacco use in adolescence. By analyzing these factors together we can disentangle the specific relevance of each of them in shaping teenagers' individual behavior. The goal of this research study is to deepen our understanding of the relationship between tobacco use in adolescence and socio-demographic and socio-emotional variables. We worked with a representative sample of 2,289 Catalan teenagers (aged 15-18) who responded to a questionnaire drawn up by the Families and Children Panel. Regression models were developed to assess the statistical associations of different mood states (sadness, nervousness and loneliness), peer-group characteristics and parenting styles, with tobacco use. The results indicate that addictive behavior is more likely when teenagers show negative mood states, controlling for socio-demographic variables and other risk factors. Among these additional factors, authoritative parenting styles reduce the risk of tobacco use, compared to authoritarian, permissive and neglectful parenting. Extensive tobacco use within the peer group is the risk factor most strongly associated with teenagers' individual behavior.

To test the hypothesis that responses to coronary heart disease (CHD) risk estimates are heightened by use of ratio formats, peer group risk information, and long time frames. Cross-sectional, experimental, between-factors design. Three regions in England. A total of 740 men and women ages 30 to 70 years. Risk perception, "emotional" response, intention to change lifestyle. Logistic regression was used to investigate the impact of numerical format (ratio vs. percentage), peer group risk (personal vs. peer group), and time frame (10-year vs. 30-year) on risk perception. Analysis of variance was used to investigate the impact of these factors on emotional response and intention to change lifestyle questions. Higher perceived risk was observed when risk was presented as a ratio (p < .001) and when it was supplemented with peer group risk estimates (p = .006). Emotional responses to risk information were heightened when risk was presented as a ratio (p = .0004) and supplemented with peer group risk estimates (p = .002). Presentation with ratios also increased intention to make lifestyle changes (p = .047). Perception of CHD risk information is affected by the presentation format. Where absolute risks may appear low, use of ratios and supplementation of personal risk estimates with peer group risk may increase risk perception.

Obstructive sleep apnea (OSA) may be related to episodes of oxygen de-saturation, hypercapnia, cardiovascular dysfunction, cor-pulmonale, and pulmonary hypertension. STOP-BANG is an acronym for eight specific questions used to assess the likelihood of OSA. If the individual exhibits three or more of these indicators, he/she should be considered to be at high risk for OSA complications. Therefore, the decision of proceeding with inpatient versus outpatient ENT surgery still remains controversial. The primary objective of the study was to identify and correlate desaturation (SPO2 <90%) episodes and risk factors. We conducted a single-center retrospective study between October 1, 2011 and August 31, 2014 in order to identify postoperative complications during the first 24 hours that justify postoperative monitoring and hospital admission. A total of 292 subjects were included for data analysis. Patients were divided into two groups based on the number of OSA risk factors: group A with 3-4 risk factors (n = 166), and group B with ≥5 risk factors (n = 126). The following information was collected: demographics, ASA, preoperative STOP-BANG score, length of surgery, intraoperative complications, opioid consumption, post anesthesia care unit (PACU) and overall length of stay, supplemental oxygen requirement, oxygen desaturation, and postoperative opioid consumption. No statistically significant difference was found when comparing demographic variables between both groups. All STOP-BANG variables showed statistical significance. PACU and inpatient variables were similar among both groups, with the exception of length of hospital stay (longer stay in group B when compared to group A [ p  = 0.003]). Desaturation differences between both groups during PACU were statistically significant ( p  = 0.008). A post-hoc analysis showed a 0% incidence of overall desaturation in the group with three STOP-BANG indicators. Our retrospective analysis concluded that patients diagnosed with three STOP-BANG risk factors did not experience postoperative complications and hospital admission was not justified. 4.

To clarify the living environment factors that increase the risk of allergic sensitization to house dust mites, we applied a regression binary tree-based method (CART, Classification & Regression Trees) to an epidemiological study on airway allergy. The utility of the tree map in personal sanitary guidance for preventing allergic sensitization was examined with respect to feasibility and validity. A questionnaire was given to 386 healthy adult women, asking them about their individual living environments. Also, blood samples were collected to measure Dermatophagoides pteronyssinus (Dp)-specific IgE, the presence/absence of Dp-sensitization being expressed as positive/negative. The questionnaire consisted of nine items on (1) home ventilation by keeping windows open, (2) personal or family smoking habits, (3) use of air conditioners in hot weather, (4) type of flooring (tatami/wooden/carpet) in the living room, (5) visible mold proliferation in the kitchen, (6) type of housing (concrete/wooden), (7) residential area (heavy or light traffic area) (8) heating system (use of unventilated combustion appliances), and (9) frequency of cleaning (every day or less often). There also were queries on the past history of airway allergic diseases, such as bronchial asthma and allergic rhinitis. CART and a multivariate logistic regression analysis (MLRA) were performed. The subjects were first classified into two groups, with and without a history of airway allergic diseases (Groups WPH and WOPH). In each group, the involvement of living environment factors in Dp-sensitization was examined using CART and MLRA. In the MLRA study, individual living environment factors showed promotional or suppressive effects on Dp-sensitization with differences between the two groups. With respect to the CART results, the two groups were first split by the factor that had the most significant odds ratio for MLRA. In Group WPH, which had a Dp-sensitization risk of 19.5%, the first split was by the factor of visible mold proliferation in the kitchen into the factor-present group with a risk value of 45.5% and the factor-absent group with 13.5%. The mold proliferation group was split with reference to frequent cleaning, and the risk rose to 75% in the factor-absent group and to 100% when family smoking habits were reported. Group WOPH (the risk: 10.8%) was first split into two groups according to the use of air conditioners in hot weather for more than 6 hours a day or less, which showed risk values of 16.7% and 6.9%, respectively. The risk of the group that intensively used air conditioners fell to 8.3% with tatami as flooring in the living room, and, if others, rose to 20.8%. The risk of the factor-lacking group fell to 4.0% without wooden flooring. CART analysis enables us to express complex relationships between living environment factors and Dp-sensitization simply by a binary regression tree, pointing to preventive strategies that can be flexibly changed according to the individual living environments of the subjects.

This study sought to assess the effect of precede-proceed model on preventive behaviors for type 2 diabetes mellitus (DM) in high-risk individuals. In this semi-experimental study, 164 high-risk individuals for type 2 DM were selected and were randomly divided into two groups of intervention and control ( n = 85). Educational intervention was performed as a single session face-to-face instruction for 1.5 hr for the intervention group participants. Data were collected before (baseline) and immediately and 1 month after the intervention in the two groups. The mean score of predisposing (knowledge) factors ( p = .001), reinforcing factors ( p = .001), and enabling factors ( p = .02) were significantly different at baseline and 1 month after the intervention in the intervention group compared with the control group ( p < .05). A significant improvement occurred in the nutritional habits of high-risk participants in the intervention group at 1 month after the intervention compared with controls ( p = .001). The precede-proceed model can be effective for promoting the preventive behaviors for type 2 DM in high-risk individuals.

Determining Leptospira spp . antibody seroprevalence in an apparently healthy population and in groups at risk plus their associated factors in the town of Villavicencio in the Meta department of Colombia A cross-sectional epidemiological model was used (subjects being selected by convenience sampling). Blood-samples were obtained by cubital puncture from (n: 503) people, consisting of 230 first semester students from different programmes at the Universidad de los Llanos and 273 people corresponding to 8 groups at risk. Information regarding risk factor was obtained from interviewing the 503 people. A commercial indirect ELISA kit (Pambio) was used for determining IgM antibodies. Seroprevalence was 5,2 % in the low risk group. There was 19 % seroprevalence for groups at risk, 7 % for the group of people working in slaughterhouses, 17 % for vets and small animal clinic assistants, 17 % for students in their last year of Veterinary Medicine and Zootechnia, 21 % for people milking cows on dual-purpose farms, 23 % for people working in rice-fields, 35 % for people working on pig-farms and 48 % for those working on fish-farms. Three factors were found to be associated: rural social level, having a pet dog and coming into contact with rodents in the workplace. A high seroprevalence for Leptospira spp was found in the groups at risk, people working on pig-farms and fish-farms being those most affected. There was a 1,86 relative risk in both groups indicated as having a greater risk of contagion amongst the population suffering occupational exposure.

To gain more insight into the prevalence rates of musculoskeletal complaints of neck-shoulder and low back and to determine the relation between physical and psychosocial work-related risk factors and the complaints mentioned in non-specialized nurses, operation room nurses, Intensive Care (IC) nurses and X-ray technologists. The study population consists of 3,169 employees affiliated to eight university hospitals in the Netherlands. The study was conducted using a cross-sectional survey design. The parameters under study were having or having had (severe) low back or neck-shoulder complaints during the past year. In logistic regression analyses odds ratio's and CI 95% were estimated for all relevant risk factors for each of the four professional groups. In all groups prevalence rates of musculoskeletal complaints were high: low back 76%, neck-shoulder 60%. Operation room nurses perceived more neck-shoulder complaints (12 months prevalence) than non-specialized nurses and IC nurses perceived less severe low back complaints than non-specialized nurses. Four physical risk factors and one psychosocial factor were associated with low back complaints in all groups. The results of the present study indicate that both low back complaints and neck-shoulder complaints are major health problems in the four professional groups under study. The prevalence rate of neck-shoulder complaints in operation room nurses is higher than in non-specialized nurses and IC nurses, the latter groups having high prevalence rates already. The exposure to risk factors is perceived differently by each of the professional groups. The professional groups under study all are target for preventive interventions; these interventions need to be specified for each of the professional groups.

The main aim of this study is to describe the differences in the cardio-ankle vascular index (CAVI) in individuals with metabolic cardiovascular risk factors or a previous history of vascular diseases (WCVRF) compared to healthy individuals (free of risk factors and previous history of vascular diseases; FCVRF) in a general Mediterranean population. The secondary aim is to describe the proportion of CAVI≥9 depending on the cardiovascular risk category in both CVRF groups by sex. The study is a descriptive analysis of 2613 participants randomly selected in the Girona province (Catalonia, Spain). CAVI mean differences between sexes and age categories in both CVRF groups followed the same pattern, the FCVRF group (men 25.2%; women 14.4%) in turn had a lower prevalence of CAVI≥9 than the WCVRF group (men 57.9%; women 51.8%). The percentage of men and women with CAVI≥9 with low risk was 13.9% and 11.3% in the FCVRF group, and 31.8% and 42.0% in the WCVRF group; with moderate risk, it was 55.8% and 10.0% in the FCVRF group and 60.3% and 49.0% in the WCVRF group. In both sexes, FCVRF groups had a lower prevalence of CAVI≥9 as well as lower mean CAVI scores, across all 10 year-age categories from 40 to 69 years, than WCVRF groups. Moreover, CAVI≥9 was frequent in individuals with low and moderate coronary risk in the WCVRF group but also in the FCVRF group. These results suggest that CAVI assessment to detect asymptomatic arteriosclerosis could be a useful tool to improve cardiovascular risk stratification. Copyright © 2017 Elsevier B.V.

Analysis of risk factors for achieving clinically overt hepatitis B and hepatitis C in the population of Bucharest municipality. retrospective and descriptive study on hospital patients cohort. Cases - in the study have been enrolled all acute viral hepatitis B and C confirmed by the two infectious diseases university clinics of Bucharest municipality, during the time interval 2001-2008, among the residents of the municipality. Infection risk factors - for every case of hepatitis B and hepatitis C with the simptoms onset placed during the time interval 2001-2008, it was associated "the most plausible" risk factor, detected by case investigation. For contemplation of control strategies the risk factors were stratified by mechanisms of virus transmission and by age groups. The analysis consists mainly in statistical comparing of cases prevalence in each etiology by risk factors and mechanisms of visus transmission. Patients cohort included 1440 hepatitis B cases and 227 hepatitis C cases, respectively. The most prevalent individual risk factor in hepatitis B was the sexual contact with multiple partners (51,0%) while in hepatitis C the use of ilegal injectable drugs (46,3%). The prevalences of hepatitis B and hepatitis C cases by the four mechanisms of virus transmmission were similar (p = 0,52). For both etiologies the high risk behaviours represented the principal mechanism of virus transmission (64,1% in hepatitis B and 63,4% in hepatitis C, respectively); additionaly, for both etiologies the most prevalent mechanisms of virus transmission by age groups were indentically, namely: (a) consumption of medical services in the age group 55+ years, (b) high risk behaviours in the age group 13-54 years and (c) contact with case or virus carrier in the age group 0-12 years, respectively. in the time period 2001 - 2008 the structure by mechanisms of virus transmission in hepatitis B and hepatitis C cases reported in the population of Bucharest municipaly was statistically similar, for both etiologies the most prevalent mechanism (> 60%) was represented by high risk behaviours. This reality strongly suggests that additionaly to the current strategies for prevention of the infection with hepatitic visuses B and C, the decisive strategy to control of the two infection needs to be extended with an effective education satelite focused on high risk groups.

The objective of this study was to evaluate the impact of a revised state-of-the-art drug prevention program, Project ALERT, on risk factors for drug use in mostly rural midwestern schools and communities. Fifty-five middle schools from South Dakota were randomly assigned to treatment or control conditions. Treatment-group students received 11 lessons in Grade 7 and 3 more in Grade 8. Effects for 4276 eighth graders were assessed 18 months after baseline. Results indicate that Project ALERT had statistically significant effects on all the targeted risk factors associated with cigarette and marijuana use and more modest gains with the pro-alcohol risk factors. The program helped adolescents at low, moderate, and high risk for future use, with the effect sizes typically stronger for the low- and moderate-risk groups. Thus, school-based drug prevention programs can lower risk factors that correlate with drug use, help low- to high-risk adolescents, and be effective in diverse school environments.

Left ventricular hypertrophy (LVH) is considered an independent risk factor even in the absence of systemic hypertension. Electrocardiographic (ECG) LVH with repolarisation changes has been found in some countries to carry more coronary risk than LVH alone. How far this observation is true among adult Nigerians is not known. We therefore decided to study adult Nigerians with ECG-LVH with or without ST-T waves changes and compare them with normal age matched controls (without ECG-LVH) in relation with established modifiable risk factors such as systemic hypertension (BP), body mass index (BMI), fasting blood sugar (FBS) and serum lipids such as total cholesterol (Tc), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG). Adult Nigerians who were consecutively referred to the ECG laboratory were randomly recruited. Three hundred patients were studied. Their blood pressures (BP) as well as body mass indices were recorded after recording their resting 12 read ECG using portable Seward 9953 ECG machine. Their waist-hip ratio (WHR) was also recorded. Blood samples were taken to determine their fasting blood sugar and serum lipids. Their ECG tracings were read by the cardiologists involved in the study while the blood samples were analysed by the chemical pathologist also involved in the study. At the end of the ECG reading, the patients were divided into 3 groups according to whether there was no ECG-LVH (control group A), ECG-LVH alone (group B), and ECG-LVH with ST-T waves changes (group C). One hundred and fifty (50%) patients belonged to group A, 100 (33.3%) patients to group B and 50 (16.7%) group C. Group B patients were found to have higher modifiable risk factors in form of systemic BP. Tc, LDL-C, and WHR compared to group A. However, the group C patients had increased load of these coronary risk factors in terms of BP elevation, higher BMI, FBS, and scrum cholesterol compared to group B. In addition, more female patients were involved in group C. The mean age of group C patients compared to group B was also significantly higher (P<0.001) even though no significant age difference was noted between group C and group A patients. It is concluded that Nigerians with ECG-LVH with ST-T waves changes have increased risk of cardiovascular risk factors compared to normal group A patients and even patients with EGC-LVH (group B) alone. Hence, they represent subset of patients to be aggressively followed up with multiple risk factors intervention.

To assess the scope and determining risk factors related to the development of pneumothorax throughout CT-guided biopsy of pulmonary lesions in coaxial and non-coaxial techniques and the outcome of its management. The study included CT-guided percutaneous lung biopsies in 650 consecutive patients (407 males, 243 females; mean age 54.6 years, SD 5.2) from November 2008 to June 2013 in a retrospective design. Patients were classified according to lung biopsy technique into coaxial group (318 lesions) and non-coaxial group (332 lesions). Exclusion criteria for biopsy were lesions <5 mm in diameter, uncorrectable coagulopathy, positive-pressure ventilation, severe respiratory compromise, pulmonary arterial hypertension, or refusal of the procedure. Risk factors related to the occurrence of pneumothorax were classified into: (a) Technical risk factors, (b) patient-related risk factors, and (c) lesion-associated risk factors. Radiological assessments were performed by two radiologists in consensus. Mann-Whitney U test and Fisher's exact tests were used for statistical analysis. p values <0.05 were considered statistically significant. The incidence of pneumothorax complicating CT-guided lung biopsy was less in the non-coaxial group (23.2 %, 77 out of 332) than the coaxial group (27 %, 86 out of 318). However, the difference in incidence between both groups was statistically insignificant (p = 0.14). Significant risk factors for the development of pneumothorax in both groups were emphysema (p < 0.001 in both groups), traversing a fissure with the biopsy needle (p value 0.005 in non-coaxial group and 0.001 in coaxial group), small lesion, less than 2 cm in diameter (p value of 0.02 in both groups), location of the lesion in the basal or mid sections of the lung (p = 0.003 and <0.001 in non-coaxial and coaxial groups, respectively), and increased needle track path within the lung tissue of more than 2.5 cm (p = 0.01 in both groups). The incidence of pneumothorax in the non-coaxial group was significantly correlated to the number of specimens obtained (p = 0.006). This factor was statistically insignificant in the coaxial group (p = 0.45). The biopsy yield was more diagnostic and conclusive in the coaxial group in comparison to the non-coaxial group (p = 0.008). Simultaneous incidence of pneumothorax and pulmonary hemorrhage was 27.3 % (21/77) in non-coaxial group and in 30.2 % (26/86) in coaxial group. Conservative management was sufficient for treatment of 91 out of 101 patients of pneumothorax in both groups (90.1 %). Manual evacuation of pneumothorax was efficient in 44/51 patients (86.3 %) in both groups and intercostal chest tube was applied after failure of manual evacuation (7 patients: 13.7 %), from which one patient developed a persistent air leakage necessitating pleurodesis. Pneumothorax complicating CT-guided core biopsy of pulmonary lesions, showed the insignificant difference between coaxial and non-coaxial techniques. However, both techniques have the same significant risk factors including small and basal lesions, increased lesion's depth from pleural surface, and increased length of aerated lung parenchyma crossed by biopsy needle and passing through pulmonary fissures in the needle tract.

Health promotion can be carried out at work places. To assess cardiovascular risk factors among workers of a University hospital. Cross sectional study of 888 participants (aged 41 ± 11 years, 76% women), who answered a survey about cardiovascular risk factors. Body mass index, waist, blood pressure and total cholesterol (TC) by capillary method were determined. Self reported prevalence of risk factors were as follows: 19% of participants had high blood pressure, 30% hypercholesterolemia, 6% diabetes, 41% smoked, 88% were sedentary and 26% had a family history of cardiovascular diseases. Five percent of participants did not have any risk factor, 20% had one risk factor, 32% had two and 43% had three or more. The highest frequency of lack of awareness was about blood glucose values. A high blood cholesterol level was found in 27% of those reporting normal cholesterol levels. Likewise, a high body mass index was found in 18% of those reporting a normal weight. The prevalence of cardiovascular risk factors in this group of participants is similar to that found in the last national health survey in Chile. Noteworthy is the lack of awareness about these risk factors.

Difference in health inequity between two population groups due to a social determinant of health.

The World Health Organization defines social determinants of health as "complex, integrated, and overlapping social structures and economic systems" that are responsible for most health inequities. Similar to the individual-level risk factors such as behavioral and biological risk factors that influence disease, we consider social determinants of health such as the distribution of income, wealth, influence and power as risk factors for risk of disease. We operationally define health inequity in a disease within a population due to a risk factor that is unfair and avoidable as the difference between the disease outcome with and without the risk factor in the population. We derive expressions for difference in health inequity between two populations due to a risk factor that is unfair and avoidable for a given disease. The difference in heath inequity between two population groups due to a risk factor increases with increasing difference in relative risks and the difference in prevalence of the risk factor in the two populations. The difference in health inequity could be larger than the difference in health outcomes between the two populations in some situations. Compared to health disparities which are typically measured and monitored using absolute or relative disparities of health outcomes, the methods presented in this manuscript provide a different, yet complementary, picture because they parse out the contributions of unfair and avoidable risk factors.

2016-01-01

In this study, we focused on the habits of wind instrumentalists as well as the presence of playing instruments, and investigated associations between the risk of temporomandibular disorders (TMD) and playing wind instruments in non-professional musicians. Seventy-two non-professional players of wind instruments (instrument group) (mean(SD), 20.0(1.1) y; 42 women) and 66 non-players (control group) (22.0(2.6) y; 45 women) participated in this study. Factors were investigated using questionnaires (a screening questionnaire for TMD, instrument playing habits, years of experience, and time played per day). The prevalence of a high risk of TMD was not significantly different between the instrument group (29.2%) and control group (21.2%). In the instrument group, the frequency of subjects who felt mouthpiece pressure in the high risk of TMD group (47.6%) was significantly greater than that in the low risk of TMD group (21.6%). Mouthpiece pressure was found to be a significant factor contributing to a high risk of TMD (odds ratio, 3.31; 95% CI, 1.12-9.79). This study suggests that pressure from the mouthpiece was one of the contributing factors related to a high risk of TMD in non-professional wind instrument players.

The objective of this study was to identify factors that could predict youth's future technology-based interpersonal victimization and the pattern of that future victimization over time. Data from Growing up With Media, a national, longitudinal, online study were analyzed. At baseline, participants (N = 1,018) were 10- to 15-year-old English speakers who had used the Internet at least once in the last 6 months. Twenty-nine percent reported repeat technology-based interpersonal victimization over a 2-year period (re-victimized group); 10% were victims during only Year 1 (desisted victimized group); and 17% reported victimization during only Year 2 (later victimized group). Of the individual risk factors examined, prior technology-based interpersonal victimization and current amount of Internet use had the strongest overall associations with pattern of technology-based interpersonal victimization over the subsequent 2-year period. There was substantial overlap among the individual risk factors. Thus, they could be thought of more simply in terms of four latent risk and three individual risk factors. On average, across these seven risk factors, repeat victims had the greatest average risk score (0.21) and the not victimized group had the lowest (-0.16). Repeat victims were more likely to be female and older and had more prior experience with problem behaviors, substance use, and negative parent-child relationships as compared with the other three groups. Being female, prior experience with problem behavior, prior substance use, and prior negative parent-child relationships were also associated with frequency of technology-based interpersonal victimization in the near (Year 1) and more distant (Year 2) future. Many of these risk factors related to technology-based victimization over time are malleable, suggesting opportunities for effective targeting of future prevention efforts.

Diverse ethnic groups may differ regarding the risk factors and severity of coronary artery disease (CAD). This study sought to assess the association between ethnicity and CAD risk and severity in six major Iranian ethnic groups. In this study, 20,165 documented coronary artery disease patients who underwent coronary angiography at a tertiary referral heart center were recruited. The demographic, laboratory, clinical, and risk factor data of all the patients were retrieved. The Gensini score (an indicator of CAD severity) was calculated for all, and the risk factors and severity of CAD were compared between the ethnical groups, using adjusted standardized residuals, Kruskal-Wallis test, and multivariable regression analysis. The mean age of the participants (14,131 [70.1%] men and 6034 [29.9%] women) was 60.7 ± 10.8 years. The Fars (8.7%) and Gilak (8.6%) ethnic groups had the highest prevalence of ≥4 simultaneous risk factors. The mean Gensini score was the highest for the Gilaks (77.1 ± 55.9) and the lowest among the Lors (67.5 ± 52.8). The multivariable regression analysis showed that the Gilaks had the worst severity (β 0.056, 95% CI 0.009 to 0.102; P = 0.018), followed by the Torks (β 0.032, 95% CI 0.005 to 0.059; P = 0.020). Meanwhile, the Lors showed the lowest severity (β -0.087, 95% CI -0.146 to -0.027; P = 0.004). This study found that there was heterogeneity in CAD severity and a diverse distribution in its well-known traditional risk factors among major Iranian ethnic groups.

This study investigated risk factors of childhood urinary tract infection (UTI) associated with extended-spectrum β-lactamase (ESBL)-producing bacteria (ESBL-positive UTI) and evaluated antimicrobial resistance as well as empiric treatment of childhood UTI. The records of children with positive urine culture between 1 January 2008 and 31 December 2012 were evaluated. Patients with positive urine culture for ESBL-producing bacteria were defined as the ESBL-positive group, whereas patients of the same gender and similar age with positive urine culture for non-ESBL-producing bacteria were defined as the ESBL-negative group. Each ESBL-positive patient was matched with two ESBL-negative patients. The ESBL-positive and negative groups consisted of 154 and 308 patients, respectively. Potential risk factors for ESBL-positive UTI were identified as presence of underlying disease, clean intermittent catheterization (CIC), hospitalization, use of any antibiotic and history of infection in the last 3 months (P < 0.05). On logistic regression analysis, CIC, hospitalization and history of infection in the last 3 months were identified as independent risk factors. In the present study, 324 of 462 patients had empiric therapy. Empiric therapy was inappropriate in 90.3% of the ESBL-positive group and in 4.5% of the ESBL-negative group. Resistance to nitrofurantoin was similar between groups (5.1% vs 1.2%, P = 0.072); resistance to amikacin was low in the ESBL-positive group (2.6%) and there was no resistance in the ESBL-negative group. Clean intermittent catheterization, hospitalization and history of infection in the last 3 months should be considered as risk factors for ESBL-positive UTI. The combination of ampicillin plus amikacin should be taken into consideration for empiric therapy in patients with acute pyelonephritis who have the risk factors for ESBL-positive UTI. Nitrofurantoin seems to be a logical choice for the empiric therapy of cystitis. © 2016 Japan Pediatric Society.

Objective. RA is associated with a 50–60% increase in risk of cardiovascular (CV) death. This study aimed to compare management of CV risk factors in RA and matched non-RA patients. Methods. A retrospective cohort study was conducted using UK clinical practice data. Patients presenting with an incident RA diagnosis were matched 1:4 to non-RA patients based on a propensity score for RA, entry year, CV risk category and treatment received at index date (date of RA diagnosis). Patients tested and treated for CV risk factors as well as those attaining CV risk factor management goals were evaluated in both groups. Results. Between 1987 and 2010, 24 859 RA patients were identified and matched to 87 304 non-RA patients. At index date, groups had similar baseline characteristics. Annual blood pressure, lipids and diabetes-related testing were similar in both groups, although CRP and ESR were higher in RA patients at diagnosis and decreased over time. RA patients prescribed antihypertensives increased from 38.2% at diagnosis to 45.7% at 5 years, from 14.0 to 20.6% for lipid-lowering treatments and from 5.1 to 6.4% for antidiabetics. Similar treatment percentages were observed in non-RA patients, although slightly lower for antihypertensives. Modest (2%) but significantly lower attainment of lipid and diabetes goals at 1 year was observed in RA patients. Conclusion. There were no differences between groups in the frequency of testing and treatment of CV risk factors. Higher CV risk in RA patients seems unlikely to be driven by differences in traditional CV risk factor management. PMID:26705329

This research has tested a social disintegration model in conjunction with risk and protection factors that have the power to differentiate relative, weighted interactions among variables in different socially disintegrated groups. The model was tested in a cross-sectional sample of 1082 at-risk youth in Switzerland. Structural equation analyses show significant differences between the social disintegration (low, moderate, high) groups and gender, indicating that the model works differently for groups and for gender. For the highly disintegrated adolescents results clearly show that the risk factors (negative mood, peer network, delinquency) are more important than the protective factors (family relations, secure sense of self). Family relations lose all protective value against negative peer influence, but personal variables, such as secure self, gain protective power.

Şan ES, Erdoğan S, Boşnak M, Şan M. Hypophosphatemia associated risk factors in pediatric intensive care patients. Turk J Pediatr 2017; 59: 35-41. The aim of this work is to determine the prevalence and risk factors of hypophosphatemia in pediatric patients admitted to intensive care unit. The study was performed prospectively in patients admitted to the Pediatric Intensive Care Unit between June 2014 and December 2014. Fifty-seven patients were included in the study. The mean age of the study population was 24 months (2-192 months); 25 patients (43.9%) were male and 32 were female (56.1%). The mean body weight z-score was -1.47 ± 2.23, and 23 (40.4%) patients had malnutrition. On admission 16 (28.1%) patients had hypophosphatemia. There were no statistically significant differences between the hypophosphatemic patient group and normophosphatemic patient groups in terms of demographic and clinical characteristics. There were also no significant differences between the two groups in terms of risk factors. Potassium and creatinine levels were significantly lower in the hypophosphatemic group, compared to the normophosphatemic group. According to a multivariate logistic regression analysis, risk factors for hypophosphatemia were low potassium level (OR: 16.76; 95% CI: 2.09 - 134.72; p: 0.008), malignant solid tumors (OR: 52.40; 95% CI: 2.04 - 1,344.32; p: 0.017, p: 0.036). and female gender (OR: 6.18; 95% CI: 1.12 - 34.00; p: 0.036). Prospective studies with larger sample size should be conducted to study the prevalence and risk factors of hypophosphatemia at pediatric intensive care unit.

A relationship exists between different cardiovascular risk factors and a significant rise in blood pressure in the presence of psychological or physical stress (cardiovascular reactivity). We studied this relationship in normotensive individuals who were subjected to stress caused by isometric exercise, which provided us with proof of the amount of weight withstood. A descriptive study was conducted in which 267 normotensive individuals were divided into two groups. One of these groups was a study group comprised of cardiovascular hyperreactive (CVHR) with a greater blood pressure response (BP)(n = 58), with BP levels > or = 90/140 mm/Hg, and the other group as a control group, with BP < 90/140 mm/Hg, n = 209. The relationship was found between the age, gender, sedentary life, smoking habit (SH), alcoholic beverage intake (ABI) and clinical history of blood pressure disorders (CH of BPD with the condition of cardiovascular hyperreactivity. 21.7% of the subjects were CVHR. The risk factors SH, ABI and gender were not related to the CVHR P > 0.05. The risk factor of CVHR is twice as high on the part of sedentary individuals, age becoming a factor as of age 40, and those individuals with a CH of BPD had twice the risk of having a cardiovascular hyperreactivity 3.85 (2: 7, 19) as those who had no CH of BPD). A significant relationship exists between being over age 40, CH of BPD and lack of exercise with a CVHR condition. This was not found to be the case for other risk factors such as SH, gender and ABI.

Traditional and non-traditional risk factors for atherosclerotic cardiovascular disease (ASCVD) are different between men and women. Gender-linked impact of epicardial adipose tissue volume (EATV) in patients undergoing coronary artery bypass grafting (CABG) remains unknown. Gender-linked impact of EATV, abdominal fat distribution and other traditional ASCVD risk factors were compared in 172 patients (men: 115; women: 57) who underwent CABG or non-coronary valvular surgery (non-CABG). In men, EATV, EATV index (EATV/body surface area) and the markers of adiposity such as body mass index, waist circumference and visceral fat area were higher in the CABG group than in the non-CABG group. Traditional ASCVD risk factors were also prevalent in the CABG group. In women, EATV and EATV index were higher in the CABG group, but other adiposity markers were comparable between CABG and non-CABG groups. Multivariate logistic regression analysis showed that in men, CABG was determined by EATV Index and other ASCVD risk factors including hypertension, dyslipidemia, adiponectin, high sensitive C-reactive protein (hsCRP) and type 2 diabetes mellitus (Corrected R2 = 0.262, p < 0.0001), while in women, type 2 diabetes mellitus is a single strong predictor for CABG, excluding EATV Index (Corrected R2 = 0.266, p = 0.005). Our study found that multiple risk factors, including epicardial adipose tissue volume and traditional ASCVD factors are determinants for CABG in men, but type 2 diabetes mellitus was the sole determinant in women. Gender-specific disparities in risk factors of CABG prompt us to evaluate new diagnostic and treatment strategies and to seek underlying mechanisms.

In this report, we update survival (OS) and time-to-progression (TTP) data for the Intergroup trial N9741 after a median 5 years of follow-up by using risk-stratified and prognostic factor analyses to determine if treatment outcomes differ in specific patient subgroups. A total of 1,691 patients were randomly assigned to one of seven fluorouracil-, oxaliplatin-, and irinotecan-containing regimens. OS and TTP were calculated by treatment arm and baseline risk group (on the basis of WBC, performance status, number of sites of disease, and alkaline phosphatase). Multivariate prognostic factor analysis was used to assess clinical factors for their relationships to OS, TTP, response, and toxicity by using Cox and logistic regression models. The observed 5-year survival with infusional fluorouracil, leucovorin, and oxaliplatin (FOLFOX) of 9.8% was better than with irinotecan plus bolus fluorouracil and leucovorin (IFL; 3.7%; P = .04) or with bolus irinotecan/oxaliplatin (IROX; 5.1%; P = .128). OS and TTP were significantly longer for FOLFOX (20.2 months and 8.9 months, respectively) than for IFL (14.6 months and 6.1 months, respectively; P < .001 for both) or for IROX (17.3 months and 6.7 months, respectively; P < .001 for both). OS differed by risk group: 20.7 months for low risk, 17.4 months for intermediate risk, and 9.4 months for high risk (P < .001). FOLFOX treatment was superior in all risk groups and was the most powerful prognostic factor for OS, TTP, response rate, and toxicity. The 9.8% 5-year OS in patients with metastatic colorectal cancer who were treated with first-line FOLFOX sets a new benchmark. Neither baseline risk group nor any prognostic factor examined was predictive of treatment-specific outcome. However, treatment efficacy and patient longevity varied as a function of risk group.

The relationship among cardiovascular disease (CVD) morbidity, risk factors (including stress), and the perception of health among male law enforcement officers (LEOs) compared to men in the general population were examined in this study. Self reported prevalence of CVD and CVD risk factors among currently employed male LEOs from nine states (n = 2,818) were compared to those of other men in the same states (n = 9,650 for CVD risk factors, n = 3,147 for CVD prevalence). Perceived stress in LEOs was assessed to determine if it affected the relationship between CVD prevalence and CVD risk factors. Cross tabulated simple percentages showed CVD was less prevalent in the LEO group than among the general population. The best predictor variables for CVD were perceived stress, time in the profession, and hypertension. The LEO group had greater prevalence of hypercholesterolemia, overweight, and tobacco use than the general population. However, a greater percentage of LEOs perceived their health as "good to excellent" compared to men in the general population. Using multivariate analysis of variance (MANOVA) it was determined that perceived stress was associated with CVD in the LEO group and three CVD risk factors (i.e., cholesterol, hypertension, physical activity) were significantly affected by perceived stress. Among susceptible officers, stress may contribute to CVD development as well as potentiate several CVD risk factors. However, an apparent lack of association exists between perception of general health and CVD risk in LEOs.

The Republic of Moldova reports the highest incidence of tuberculosis and the lowest treatment success rate among European region countries. In most of the patients the antituberculosis treatment failure is correlated with social risk factors (low socio-economical state, epidemiological danger characteristics) and biological factors (young age, male sex, physiological conditions, associated diseases). Clinical factors (advanced forms of tuberculosis, chronic evolution, immune disturbances), therapeutic factors (treatment errors and interruptions, individualized regimens) and administrative factors (drug interruption in supply, suboptimal treatment quality) prevail in regions with defficient in health care delivery. The association of risk factors has a higher impact than the severity of one risk factor. The risk factor assessment is very important before initiation of the treatment, for establishing the plan of risk reduction measures for increasing the success rate. The aim of the study was to determine the impact of exogenous risk factors on antituberculosis treatment failure. The study was conducted on 201 patients with pulmonary tuberculosis and treatment failure and 105 patients with pulmonary tuberculosis who successfully finished the antituberculosis treatment. Selected cases were investigated according national standards. The treatment failure occurred in patients belonging to socially disadvantaged groups, patients with harmful habits (alcohol abuse, drug use, active smoking), patients from infectious clusters. Migration, homelessness and detention releasing imperil the quality of treatment, thus predisposing to the treatment failure. Social, educational support and the substitutive therapy and withdrawal techniques (tobacco, alcohol, psycho-active substances) must be implemented in the high risk groups in order to diminish the risk of treatment failure and to increase the treatment success rate. The study of exogenous risk factors in vulnerable groups will contribute to the precocious detection of patients predisposed to failing the tuberculosis treatment and will permit the initiation of measures centered on patient that will favor the increase of treatment quality and success rate.

Emerging evidence supports an association between metabolic risk factors and bone turnover. Statins and exercise independently improve metabolic risk factors; however whether improvements in metabolic risk factor affects bone turnover is unknown. The purpose of the present study was to: 1) evaluate the relationship between metabolic risk factors and bone turnover; and 2) determine if improvements in metabolic risk factors after 12 weeks of statin treatment, exercise or the combination affect bone turnover. Fifty participants with ≥2 metabolic syndrome defining characteristics were randomly assigned to one of three groups: statin (STAT: simvastatin, 40 mg/day), exercise (EX: brisk walking and/or slow jogging, 45 minutes/day, 5 days/week), or the combination (STAT+EX). Body composition and whole body bone mineral density were measured with dual energy X-ray absorptiometry. Serum markers of bone formation (bone specific alkaline phosphatase, BAP; osteocalcin, OC), resorption (C-terminal peptide of type I collagen, CTX) and metabolic risk factors were determined. Two-factor (time, group) repeated-measures ANCOVA was used to examine changes of metabolic risk factors and bone turnover. General linear models were used to determine the effect of pre-treatment metabolic risk factors on post-treatment bone turnover marker outcomes. Participants with ≥4 metabolic syndrome defining characteristics had lower pre-treatment OC than those with 3 or fewer. OC was negatively correlated with glucose, and CTX was positively correlated with cholesterol. STAT or STAT+EX lowered total and LDL cholesterol. The OC to CTX ratio decreased in all groups with no other significant changes in bone turnover. Higher pre-treatment insulin or body fat predicted a greater CTX reduction and a greater BAP/CTX increase. Metabolic risk factors were negatively associated with bone turnover markers. Short-term statin treatment with or without exercise lowered cholesterol and all treatments had a small effect on bone turnover. Copyright © 2014 Elsevier Inc. All rights reserved.

Cardiovascular disease (CVD) is the leading cause of death throughout the world. Despite its high prevalence, the atherosclerotic process can be slowed and its consequences markedly reduced by preventive measures. The lack of risk factor awareness is a major barrier. We aimed to assess total CV risk, determine the knowledge and awareness regarding CVD, and evaluate the effectiveness of education program in urban population of Turkey. A 24-item questionnaire was used to detect CV risk factors and the awareness of participants about CVD. The feedback data for the education program were collected by either questionnaires or individual interviews with participants. For comparison of total CVD risk in men and women in different age groups, a sample t test was used. The level of statistical significance was set at p < 0.05. The prevalence of hyperlipidemia was established to be 41.3%. Nearly one-quarter of the women and one-third of the men were smokers (p < 0.001). One-quarter of the responders had a history of hypertension (men: 21.5%, women: 18.6%), and one-tenth were diabetic. The high CV risk rate was more pronounced among men (p < 0.01) and those with low socioeconomic level (p < 0.01). Awareness regarding CV risk factors following the educational program increased from 6.6% to 12.7% for high blood pressure, from 3.9% to 9.2% for diabetes mellitus, and from 10.2% to 15.1% for elevated cholesterol levels. All the increases were statistically significant. The educational program significantly increased the awareness of CVD and risk factors. The prevalence of CV risk factors was higher in low socioeconomic level groups. The knowledge and awareness of the risk factors for CVD before the education program was very low in our study group. The awareness of CVD and risk factors significantly increased following our education programs. Copyright © 2013 World Heart Federation (Geneva). Published by Elsevier B.V. All rights reserved.

Cardiovascular diseases stem from modifiable risk factors. Peer support is a proven strategy for many chronic illnesses. Randomized trials assessing the efficacy of this strategy for global cardiovascular risk factor modification are lacking. This study assessed the hypothesis that a peer group strategy would help improve healthy behaviors in individuals with cardiovascular risk factors. A total of 543 adults 25 to 50 years of age with at least 1 risk factor were recruited; risk factors included hypertension (20%), overweight (82%), smoking (31%), and physical inactivity (81%). Subjects were randomized 1:1 to a peer group-based intervention group (IG) or a self-management control group (CG) for 12 months. Peer-elected leaders moderated monthly meetings involving role-play, brainstorming, and activities to address emotions, diet, and exercise. The primary outcome was mean change in a composite score related to blood pressure, exercise, weight, alimentation, and tobacco (Fuster-BEWAT score, 0 to 15). Multilevel models with municipality as a cluster variable were applied to assess differences between groups. Participants' mean age was 42 ± 6 years, 71% were female, and they had a mean baseline Fuster-BEWAT score of 8.42 ± 2.35. After 1 year, the mean scores were significantly higher in the IG (n = 277) than in the CG (n = 266) (IG mean score: 8.84; 95% confidence interval (CI): 8.37 to 9.32; CG mean score: 8.17; 95% CI: 7.55 to 8.79; p = 0.02). The increase in the overall score was significantly larger in the IG compared with the CG (difference: 0.75; 95% CI: 0.32 to 1.18; p = 0.02). The mean improvement in the individual components was uniformly greater in the IG, with a significant difference for the tobacco component. The peer group intervention had beneficial effects on cardiovascular risk factors, with significant improvements in the overall score and specifically on tobacco cessation. A follow-up assessment will be performed 1 year after the final assessment reported here to determine long-term sustainability of the improvements associated with peer group intervention.

Objective The aim of this study was to determine the roles of biopsychosocial risk factors in the development of breast cancer. Materials and methods This hospital-based case-control study included 491 women with breast cancer (study group) and 512 women who did not have cancer or other serious diseases (control group). Biological, psychological, and social risk factors were compared between the two groups. Data were collected using the semi-structured interview, the Stress Assessment Form, and the Coping Strategy Indicator to assess these factors. Results When the significantly different biopsychosocial variables between the study and the control groups were evaluated together, independent breast cancer risk factors were found as follows: a stressor experienced in the last 5 years, age 40 years and older, inadequate social support perception, use of avoidance coping strategy, being a housewife, having a family history of cancer, and having a body mass index ≥25. Conclusion This study showed a relationship between breast cancer risk and manageable variables (obesity, stressor and coping strategy, social support, and employment status), age and family history of cancer, which are biopsychosocial factors. Biopsychosocial aspects are becoming a greater part of many different healthcare systems. PMID:29082379

To investigate perceptions of dementia and dementia risk reduction held by people without dementia. Dementia does not only affect individuals with dementia, but also has an impact on family and friends, society and healthcare professionals. Recent research has identified modifiable risk and protective factors for dementia. However, it is unclear what knowledge people without dementia have about these risk factors and their attitudes towards addressing these risk factors to achieve dementia risk reduction are not known. Qualitative descriptive study using focus group methodology. A focus group study was conducted in February 2011 with 34 older adults aged between 52-90 years. The long-table approach was used to identify themes and categorize data on dementia knowledge, risk and attitudes. Participants correctly identified dementia risk factors as a group. Participants' responses about their perceived likelihood of developing dementia could be classified into three distinctive themes; fear, rational and cynical perceptions. Both fear of developing dementia and the need to improve dementia knowledge were considered major motivators towards adopting healthier lifestyle and health behaviours. Lack of knowledge on risk factors for dementia was identified as a major barrier for behavioural and lifestyle change. These findings can be used to develop effective and personalized interventions that increase motivators and reduce barriers by tailoring interventions to individual's dementia risk reduction literacy and motivations to change behaviours. Greater public-health promotion and education about risk and protective factors for dementia are also necessary to increase dementia health literacy and to reduce overall dementia prevalence. © 2015 John Wiley & Sons Ltd.

We wanted to compare the efficacy of haploidentical hematopoietic stem cell transplantation (HSCT) with chemotherapy alone in adults with standard-risk acute lymphoblastic leukemia (ALL) in first complete remission (CR1). One hundred thirty-eight consecutive adult patients with standard-risk ALL in CR1 were retrospectively investigated. Of these patients, 59 received chemotherapy alone (group A) and 79 received unmanipulated haploidentical HSCT (group B). Cumulative incidence of relapse at 5 years in group A was significantly higher than that in group B (66.3% versus 29.9%, P < .0001). Overall and disease-free survival in group A were significantly inferior to group B (P < .0001). Moreover, multivariate analyses demonstrated that central nervous system leukemia (P = .002), T cell immunophenotype (P = .044), expression of E2A-PBX1 (P = .007), and positive minimal residual disease after the first cycle of consolidation (P = .004) were correlated with relapse. Patients with 1 of 4 risk factors were assigned to the high-risk group. Otherwise, patients without risk factors were assigned to the low-risk group. In the high-risk group, HSCT had lower relapse rates and superior DFS compared with chemotherapy (P < .05), but in the low-risk group, there were no differences between HSCT and chemotherapy (P > .05). This study is the first to demonstrate that compared with chemotherapy alone, haploidentical HSCT is a better postremission therapy in adults with standard-risk ALL in CR1. Moreover, based on the 4 risk factors, the establishment of risk stratification could identify the subgroup of patients with a higher risk of relapse in adults with standard-risk ALL in CR1. Furthermore, risk stratification-directed postremission therapies using haploidentical HSCT or chemotherapy alone not only reduce relapse rate but also avoid unnecessary treatment-related mortality and improve survival.

To assess the relationship between modifiable health risks and total health care expenditures for a large employee group. Risk data were collected through voluntary participation in health risk assessment (HRA) and worksite biometric screenings and were linked at the individual level to health care plan enrollment and expenditure data from employers' fee-for-service plans over the 6-year study period. The setting was worksite health promotion programs sponsored by six large private-sector and public-sector employers. Of the 50% of employees who completed the HRA, 46,026 (74.7%) met all inclusion criteria for the analysis. Eleven risk factors (exercise, alcohol use, eating, current and former tobacco use, depression, stress, blood pressure, cholesterol, weight, and blood glucose) were dichotomized into high-risk and lower-risk levels. The association between risks and expenditures was estimated using a two-part regression model, controlling for demographics and other confounders. Risk prevalence data were used to estimate group-level impact of risks on expenditures. Risk factors were associated with 25% of total expenditures. Stress was the most costly factor, with tobacco use, overweight, and lack of exercise also being linked to substantial expenditures. Modifiable risk factors contribute substantially to overall health care expenditures. Health promotion programs that reduce these risks may be beneficial for employers in controlling health care costs.

The study examines the influence of specific risks on parenting at the beginning of youth welfare measures. Family risk factors as well as parental behaviour styles of N = 74 parents were assessed with standardized questionnaires. The results were evaluated cross-sectionally with one-way factor analysis. Three groups were formed according to degree of risk factors. Families with special risks, i.e., material needs, physically ill parents, or single parents, show a significantly lower level of parenting competence. Differences in negative parenting features are not found to be under the influence of specific risks. Parents of children in youth welfare measures who are specifically stressed may need special training to increase their parenting skills, especially when pre-post comparisons show lower parenting quality in the group with specific risk factors at the end of an intervention.

Patients with inflammatory bowel disease (IBD) are at high risk of developing osteoporosis. Our objective was to determine the usefulness of IBD guidelines in identifying patients at risk for developing osteoporosis. We utilized institutional repository to identify patients seen in IBD center and extracted data on demographics, disease history, conventional, and nonconventional risk factors for osteoporosis and Dual Energy X-ray Absorptiometry (DXA) findings. 59% of patients (1004/1703) in our IBD cohort had at least one risk factor for osteoporosis screening. DXA was documented in 263 patients with indication of screening (provider adherence, 26.2%), and of these, 196 patients had DXA completed ("at-risk" group). Ninety-five patients not meeting guidelines-based risk factors also had DXA completed ("not at-risk" group). 139 (70.9%) patients in "at-risk" group had low BMD, while 51 (53.7%) of "not-at-risk" patients had low BMD. Majority of the patients with osteoporosis (83.3%) missed by the current guidelines had low BMI. Multivariate logistic regression analysis showed that low BMI was the strongest risk factor for osteoporosis (OR 3.07; 95% CI, 1.47-6.42; P = 0.003). Provider adherence to current guidelines is suboptimal. Low BMI can identify majority of the patients with osteoporosis that are missed by current guidelines.

Suicide is a serious public health concern worldwide, and the fourth leading cause of death in Korea. Few studies have focused on risk factors for suicide attempt among people with suicidal ideation. The aim of the present study was to investigate the risk factors and develop prediction models for suicide attempt among people with suicidal ideation in the Korean population. This study included 1567 men and 3726 women aged 20 years and older who had suicidal ideation from the Korea National Health and Nutrition Examination Survey from 2007 to 2012. Among them, 106 men and 188 women attempted suicide. Multivariate logistic regression analysis with backward stepwise elimination was performed to find risk factors for suicide attempt. Sub-group analysis, dividing participants into under 50 and at least 50 years old was also performed. Among people with suicidal ideation, age, education, cancer, and depressive disorder were selected as risk factors for suicide attempt in men. Age, education, national basic livelihood security, daily activity limitation, depressive disorder, stress, smoking, and regular exercise were selected in women. Area under curves of our prediction models in men and women were 0.728 and 0.716, respectively. It is important to pay attention to populations with suicidal ideation and the risk factors mentioned above. Prediction models using the determined risk factors could be useful to detect high-risk groups early for suicide attempt among people with suicidal ideation. It is necessary to develop specific action plans for these high-risk groups to prevent suicide.

Electrolyte imbalance is a common problem affecting the elderly. Increased number of comorbidities and frequent use of drugs may contribute to increased risk of hypokalemia in the elderly. This study was performed to investigate the prevalence of community-acquired hypokalemia (CAH), risk factors for its development, related factors with hypokalemia, and morbidities and all-cause mortality rates (MR) of CAH in the elderly patients. Total of 36,361 patients aged above 65 years were screened retrospectively. Group 1 consisted of 269 elderly patients with potassium level ≤3.5 mmol/L, and group 2 (control group) consisted of 182 subjects with potassium level between 3.6 and 5.5 mmol/L. Etiologic factors of CAH, presence of comorbidities, duration of hospital stay, hospital cost, and clinical outcomes were recorded. Prevalence of hypokalemia was found 3.24% in patients aged above 65 years. Duration of hospital stay, presence of ≥2 comorbid diseases, hospital cost, and MR were significantly higher in group 1 compared to group 2 (p < 0.001 for all). Loop diuretics, hydrochlorothiazides, beta agonists, inadequate oral intake, and female gender were all independent risk factors for CAH in elderly patients. Patients with ≥2 comorbid diseases were found to have greater risk of hypokalemia than the patients with <2 comorbidities. Length of hospital stay, hospital cost, and MR were higher in elderly with CAH. Female gender, hydrochlorothiazides, loop diuretics, and ≥2 comorbid diseases are the leading risk factors associated with CAH in elderly.

Pancreatic fistula (PF) remains the most challenging complication after pancreaticoduodenectomy (PD). The purpose of this study was to identify the risk factors of PF and delineate its impact on patient outcomes. We retrospectively reviewed clinical data of 532 patients who underwent PD and divided them into PF group and no PF group. Risk factors and outcomes of PF following PD were examined. PF was found in 65 (12.2%) cases, of whom 11 were classified into ISGPF grade A, 42 grade B, and 12 grade C. Clinically serious postoperative complications in the PF versus no PF group were mortality, abdominal bleeding, bile leak, intra-abdominal abscess and pneumonia. Univariate and multivariate analysis showed that blood loss ≥ 500 ml, pancreatic duct diameter ≤ 3 mm and pancreaticojejunostomy type were independent risk factors of PF after PD. Blood loss ≥ 500 ml, pancreatic duct diameter ≤ 3 mm and pancreatico-jejunostomy type were independent risk factors of PF after PD. PF was related with higher mortality rate, longer hospital stay, and other complications.

Work-related stress (WRS) is known to cause ill-health and decreased productivity. Work in the education sector is thought to be particularly stressful. Few studies have considered risk factors for WRS and health in head teachers. To investigate health in head teachers in West Sussex. To determine personal risk factors most likely to predict cases of WRS and of poor health in head teachers. A cross-sectional study, in a population of 290 head teachers and principals of colleges of further education, using a validated questionnaire, 'a short stress evaluation tool' (ASSET) and additional questions derived from earlier studies. Results were compared with the ASSET database 'norm' groups: a general population of workers (GPN) group and a group of managers and professionals (MPN). 'Caseness' was defined as respondents who felt work was 'very or extremely stressful'. Head teachers had poor physical and mental health compared to the GPN group. Psychological well-being, particularly of females and primary head teachers was worse than a comparative group of managers and professionals. Teaching<5 h/week was a significant predictor of caseness and being female was the main risk factor for poor psychological well-being. Prevalence of self-reported stress in head teachers in West Sussex is high. Female head teachers had worse health outcomes. Our study identified possible personal risk factors predicting WRS and/or poor health in head teachers.

Abstract To identify the epidemiology, treatments, outcomes, and risk factors for patients with early- or late-onset invasive candidiasis (EOIC or LOIC) in intensive care units in China. Patients were classified as EOIC (≤10 days) or LOIC (>10 days) according to the time from hospital admission to IC onset to identify distinct clinical characteristics. There were 105 EOIC cases and 201 LOIC cases in this study. EOIC was related to more severe clinical conditions at ICU admission or prior to IC. Significantly, more cases of Candida parapsilosis infection were found in patients with LOIC than in those with EOIC. The mortality of EOIC was significantly lower than that for LOIC. Sequential Organ Failure Assessment (SOFA) score at ICI diagnosis in the EOIC group and the interval from ICU admission to ICI occurrence in the LOIC group were identified as risk factors for mortality. Susceptibility to the first-line agent was associated with a lower risk of mortality in the LOIC group. The mortality rate was significantly lower in the EOIC group, and there were more cases of non-albicans infection in the LOIC group. Susceptibility to the first-line agent was an important predictor of mortality in the LOIC group. SOFA score at ICI diagnosis in the EOIC group and interval from ICU admission to ICI occurrence in the LOIC group were identified as risk factors for mortality. PMID:29049184

There is an increasing gap between organ supply and demand for cadaveric transplantation in our country. Our aim was to evaluate factors affecting selection of patients on waiting list at our hospital. Patients who have been waiting on list and who were transplanted were compared in order to find factors, which affected the selection of patients. Non-parametric Mann-Whitney U test was used for comparison and cox regression analysis was used to find the risk factors that decrease the probability of transplantation in this retrospective case-control study. Patients in the transplanted group were significantly younger, had relatively lower body mass index than the awaiting group. Cardiovascular diseases were more in the awaiting group than the transplanted group. There was no patient with diabetes in transplanted group, despite fifteen diabetic patients were in the awaiting group. Selected patients had lower immunologic risk with regard to peak panel reactive antibody levels. No significant difference was found for gender, hypertension, hyperlipidemia, viral serology, time spent on dialysis and on waiting list between two groups. With cox regression analysis female gender, older age, diabetes mellitus, high body mass index, positive hepatitis B serology and high levels of peak class 1-2 peak panel reactive antibody positivity were found as risk factors that decrease the probability of transplantation. A tendency for selection of low risk patients was found with this study. Time and energy consuming complications and short allograft survival after transplantation in high risk patients and the scarcity of cadaveric pool in our country may contribute to this tendency.

Whether low-volume, high-intensity, interval training (HIIT) is an adequate exercise method for improving metabolic risk factors is controversial. Moreover, it is not known if performing a short-term, low-calorie diet intervention (LCDi) after a HIIT program affects risk factors. This study investigated how an 8-week, 3 times/week exercise intervention (EXi) incorporating either HIIT or moderate-intensity continuous training (MICT) followed by a 4-week LCDi affects risk factors. Twenty-six male workers with metabolic risk factors (47.4 ± 7.1 years; cardiorespiratory capacity (VO2peak) of 28.5 ± 3.9 ml/kg/min) were randomly assigned to either the HIIT (3 sets of 3-min cycling with a 2-min active rest between sets, 180 kcal) or MICT (45 min, 360 kcal) group. After the EXi, all subjects participated in a 4-week LCDi (4 counseling sessions). During the EXi, VO2peak improved more (P < 0.05) through HIIT (25.4 ± 14.6%) than through MICT (14.9 ± 12.8%), whereas improvements in body fat and HDL cholesterol were similar. During the LCDi, some risk factors improved further (P < 0.05) without any group differences, while VO2peak in the HIIT group decreased (P < 0.05) to the same level as in the MICT group. VO2peak increased more with HIIT than with MICT during the EXi despite HIIT having a lower exercise volume than MICT, but this advantage of HIIT promptly disappeared through detraining. An intervention strategy consisting of 8 weeks of either HIIT or MICT followed by a 4-week LCDi has a positive effect on metabolic risk factors. UMIN11352. Copyright © 2015 Elsevier B.V.

(1) BACKGROUND: Musculoskeletal disorders have a multifactorial etiology that is not only associated with physical risk factors, but also psychosocial risk factors; (2) OBJECTIVE: This study evaluated the effects of an ergonomic intervention on musculoskeletal disorders and psychosocial risk factors; (3) MATERIAL AND METHODS: This study took a participatory ergonomic (PE) approach with a randomized controlled trial (RCT) conducted at tertiary care hospitals during July to December 2014. A group of hospital orderlies in Thailand were randomly selected for examination. Fifty orderlies were placed in a case group and another 50 orderlies were placed in the control group. The Nordic Musculoskeletal Disorders Questionnaire (NMQ) and the Copenhagen Psychosocial Questionnaire (COPSOQ) were used for data collection before and after the intervention program; (4) RESULTS: The most commonly reported problem among hospital orderlies was found to be lower back symptoms (82%). The study found significant differences in prevalence rates of reported musculoskeletal conditions in the arm, upper back, and lower back regions before and after intervention. Findings showed that psychosocial risk factors were affected by the intervention. COPSOQ psychosocial risk factors were significantly different pre/post intervention. These variables included: work pace, influence at work, meaning of work, predictability, rewards, role conflicts, and social support from supervisors. No other psychosocial risk factors were found to be significant; (5) CONCLUSIONS: Positive results were observed following the intervention in the work environment, particularly in terms of reducing physical work environment risk factors for musculoskeletal disorders and increasing promotion factors of the psychosocial work environment.

The aim of the study was to evaluate color vision and its diagnostic value in predicting the risk of diabetic retinopathy in patients with glucose metabolism disorders. The study involved 197 people, 92 women and 105 men aged 63.21 ± 8.74 years. In order to assess glucose metabolism disorders, patients were divided into three groups. The first group (DM) consisted of 60 people (16 women and 44 men aged 61.92 ± 8.46 years). These were people with type 2 diabetes. Second group (IFG IGT) consisted of 67 people (35 women and 32 men aged 65 ± 8.5 years). These were people who were diagnosed with impaired fasting glucose or impaired glucose tolerance. The third group, the control one (K) consisted of 70 people (41 women and 29 men aged 62.6 ± 9.06 years). They were healthy individuals. In order to assess diabetic retinopathy study population was divided into two groups. The first group (BZ) consisted of 177 patients (84 women and 93 men aged 62.9 ± 8.78 years) without diabetic retinopathy. The second group (NPDR) consisted of 20 patients (8 women and 12 men aged 65.95 ± 8.17 years) with diabetic retinopathy. Glucose metabolism disorders were diagnosed with glucose tolerance test (OGTT). Evaluation of retinopathy was based on eye examination. All patients underwent binocular Farnsworth-Munsell 100 Hue color vision test (test result is a Total Error Score - TES). In the healthy control group (K) there were less patients with diabetic retinopathy (p = 0,0101), and less patients with abnormal color vision test (p = 0,0001) than in other groups. Majority of patients in K group had generalized abnormalities of color vision while other groups demonstrated tritanomalią (p = 0,0018). It was discovered that sTES value adequately distinguishes group K from group IFG, IGT, DM (AUC = 0,673), group K from group DM (AUC = 0,701), and group K from group IFG IGT (AUC = 0,648) sTES does not differentiate groups IGT, IFG and DM (AUC = 0,563). It was shown that in IGT, IFG group sTES was an independent risk factor that increased the risk of prediabetes almost six times (OR 5,924, 95% CI [1,169- 30,036], p = 0,032). In DM group sTES was an independent risk factor, which increased the risk of diabetes more than thirteen times (OR 13,408, 95% CI [2,324-77,345], p = 0,004). Higher values of sTES occurred in patients with retinopathy (NPDR) (p <0,001) and multivariate analyzes demonstrated that sTES ≥1.04 was an independent risk factor that increased the risk of retinopathy over twenty times (OR 21,380, 95% CI [1,101 -89,241], p <0,001). sTES is an independent risk factor for glucose metabolism disorders that increases the risk of prediabetes almost six times and the risk of diabetes more than thirteen times. sTES ≥1,04 is an independent risk factor for diabetic retinopathy. sTES ≥1,04 increases the risk of diabetic retinopathy over twenty times. The color vision 100 Hue test can be useful in detecting glucose metabolism disorders even before the ophthalmoscopic manifestation of retinopathy. Early detection rises the possibility to prevent or delay the development of diabetes through lifestyle changes and implementation of healthy behaviors.

Paget's disease of bone (PDB) may lead to hearing loss. The present study was conducted with the aim of measuring, characterizing and determining the risk factors for hearing loss in a group of subjects with PDB. An observational, transversal, case-control study was conducted, a cohort of 76 subjects diagnosed with PDB in the case group and a control group of 134 subjects were included. Clinical, demographic and audiometric data were analysed. The comparative analysis between the subjects in the PDB group and the control group found that the case group showed higher hearing thresholds (39,51dB) compared with the control group (37.28dB) (P=.069) and presented a greater rate of conductive hearing loss (22.76%) than the control group (12.05%) (P=.0062). The study of risk factors for hearing loss found that skull involvement in bone scintigraphy, age and high blood pressure were risk factors for higher impairment in PDB. The subjects with PDB showed more profound and a higher proportion of conductive hearing loss than the control group. The patients with PDB and skull involvement presented a more severe hearing loss compared with the subjects without skull involvement. Skull involvement and age were found to be risk factors for hearing loss. Copyright © 2018 Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello.

Mental illness, substance abuse, and poverty are risk factors for violent injury, and violent injury is a risk factor for early mortality that can be attenuated through hospital-based violence intervention programs. Most of these programs focus on victims under the age of 30 years. Little is known about risk factors or long-term mortality among older victims of violent injury. To explore the prevalence of risk factors for violent injury among younger (age < 30 years) and older (age 30 ≥ years) victims of violent injury, to determine the long-term mortality rates in these age groups, and to explore the association between risk factors for violent injury and long-term mortality. Adults with violent injuries were enrolled between 2001 and 2004. Demographic and injury data were recorded on enrollment. Ten-year mortality rates were measured. Descriptive analysis and logistic regression were used to compare older and younger subjects. Among 541 subjects, 70% were over age 30. The overall 10-year mortality rate was 15%, and was much higher than in the age-matched general population in both age groups. Risk factors for violent injury including mental illness, substance abuse, and poverty were prevalent, especially among older subjects, and were each independently associated with increased risk of long-term mortality. Mental illness, substance abuse, and poverty constitute a "lethal triad" that is associated with an increased risk of long-term mortality among victims of violent injury, including both younger adults and those over age 30 years. Both groups may benefit from targeted risk-reduction efforts. Emergency department visits offer an invaluable opportunity to engage these vulnerable patients. Copyright © 2018 Elsevier Inc.

Obesity, Diabetes, and Other Cardiovascular Risk Factors in Native Populations of South America.

PubMed

Ingaramo, Roberto A

2016-01-01

Cardiovascular disease remains the leading cause of death in both developed and developing countries. In South America, the native population comprises a great number of different ethnic groups. The cardiovascular risk factors observed in these groups have proved similar to and even higher than those found in general non-native populations. Relatively recent epidemiologic information reveals that many native communities have healthy habits with low prevalence of risk factors such as hypertension and diabetes, while their prevalence is higher in those who have kept close contact with non-native populations and have westernized their habits. The differences in the presence of risk factors in these populations have been explained as the result of several interacting factors including genetic to environmental, socioeconomic, and cultural causes.

The aim of the study was to identify risk factors associated with postoperative urinary tract infections (UTIs) following hysterectomy-based surgical staging in women with endometrial cancer. This is a retrospective study utilizing an institutional database (2008-2016) of stage I-IV endometrial cancer cases that underwent hysterectomy-based surgery. UTIs occurring within a 30-day time period after surgery were examined and correlated to patient clinico-pathological demographics. UTIs were observed in 44 (6.4%, 95% confidence interval 4.6-8.2) out of 687 cases subsequent to the diagnosis of endometrial cancer. UTI cases were significantly associated with obesity, advanced stage, prolonged operative time, hysterectomy type, pelvic lymphadenectomy, non-β-lactam antibiotics, and intraoperative urinary tract injury (all, p < 0.05). On multivariate analysis, three independent risk factors were identified for UTIs: prolonged operative time [odds ratio (OR) 3.36, 95% CI 1.65-6.87, p = 0.001], modified-radical/radical hysterectomy (OR 5.35, 95% CI 1.56-18.4, p = 0.008), and an absence of perioperative β-lactam antibiotics use (OR 3.50, 95% CI 1.46-8.38, p = 0.005). In a predictive model of UTI, the presence of multiple risk factors was associated with significantly increased risk of UTI: 4.1% for the group with no risk factors, 7.3-12.5% (OR 1.85-3.37) for single risk factor group, and 30.0-30.8% (OR 10.1-10.5) for two risk factor group. Urinary tract infections are common in women following surgical treatment for women with endometrial cancer with risk factors being a prolonged surgical time, radical hysterectomy, and non-guideline perioperative anti-microbial agent use. Consideration of prophylactic anti-microbial agent use in a high-risk group of postoperative urinary tract infection merits further investigation.

Few studies have analyzed the development course beginning in pre-/early adolescence of overall engagement in health-risk behaviors and associated social risk factors that place individuals in different health-risk trajectories through mid-adolescence. The current longitudinal study identified 1276 adolescents in grade six and followed them for three years to investigate their developmental trajectories of risk behaviors and to examine the association of personal and social risk factors with each trajectory. Group-based trajectory modeling was applied to identify distinctive trajectory patterns of risk behaviors. Multivariate multinomial logistic regression analyses were performed to examine the effects of the personal and social risk factors on adolescents' trajectories. Three gender-specific behavioral trajectories were identified for males (55.3% low-risk, 37.6% moderate-risk, increasing, and 7.1% high-risk, increasing) and females (41.4% no-risk, 53.4% low-risk, increasing and 5.2% moderate to high-risk, increasing). Sensation-seeking, family, peer, and neighborhood factors at baseline predicted following the moderate-risk, increasing trajectory and the high-risk, increasing trajectory in males; these risk factors predicted following the moderate to high-risk, increasing trajectory in females. The presence of all three social risk factors (high-risk neighborhood, high-risk peers and low parental monitoring) had a dramatic impact on increased probability of being in a high-risk trajectory group. These findings highlight the developmental significance of early personal and social risk factors on subsequent risk behaviors in early to middle adolescence. Future adolescent health behavior promotion interventions might consider offering additional prevention resources to pre- and early adolescent youth who are exposed to multiple contextual risk factors (even in the absence of risk behaviors) or youth who are early-starters of delinquency and substance use behaviors in early adolescence.

Abstract Objective: to evaluate the effect and gender differences of an innovative intervention involving in-person and telephone nursing counseling to control cardiovascular risk factors (arterial hypertension, dyslipidemia, and overweight), improve health-related quality of life and strengthen self-efficacy and social support in persons using the municipal health centers' cardiovascular health program. Method: a randomized controlled clinical trial involving participants randomized into the intervention group who received traditional consultation plus personalized and telephone nursing counseling for 7 months (n = 53) and the control group (n = 56). The study followed the Consolidated Standards of Reporting Trials Statement. Results: women in the intervention group presented a significant increase in the physical and mental health components compared to the control group, with decreases in weight, abdominal circumference, total cholesterol, low-density lipoprotein cholesterol, and the atherogenic index. The effects attributable to the intervention in the men in the intervention group were increased physical and emotional roles and decreased systolic and diastolic pressure, waist circumference, total cholesterol, low-density lipoprotein cholesterol, atherogenic index, cardiovascular risk factor, and 10-year coronary risk. Conclusion: this intervention is an effective strategy for the control of three cardiovascular risk factors and the improvement of health-related quality of life. PMID:27508917

Patients who have undergone angioplasty experience difficulty modifying at-risk behaviors for subsequent cardiac events. The purpose of this study was to test whether an innovative approach to framing of risk, based on 'net present value' economic theory, would be more effective in behavioral intervention than the standard 'future value approach' in reducing cardiovascular morbidity and mortality following angioplasty. At baseline, all patients completed a health assessment, received an individualized risk profile and selected risk factors for modification. The intervention randomized patients into two varying methods for illustrating positive effects of behavior change. For the experimental group, each selected risk factor was assigned a numeric biologic age (the net present value) that approximated the relative potential to improve current health status and quality of life when modifying that risk factor. In the control group, risk reduction was framed as the value of preventing future health problems. Ninety-four percent of patients completed 2-year follow-up. There was no difference between the rates of death, stroke, myocardial infarction, Class II-IV angina or severe ischemia (on non-invasive testing) between the net present value group and the future value group. Our results show that a net present risk communication intervention did not result in significant differences in health outcomes.

To evaluate the histopathological findings of type C liver disease to determine risk factors for development of hepatocellular carcinoma (HCC). We studied 232 patients, who underwent liver biopsy for type C chronic liver disease between 1992 and 2009, with sustained virological response (SVR) after interferon therapy. The patients were divided into two groups according to the F stage 0 + 1 + 2 group (n = 182) and F3 + 4 group (n = 50). We prospectively observed and compared the incidence of HCC of the patients with SVR in the F0 + 1 + 2 and F3 + 4 groups. Then, the background factors and liver histopathological findings, including the degree of fibrosis, F stage, inflammation, necrosis, bile duct obstruction, fat deposition, and degree of irregular regeneration (IR) of hepatocytes, were correlated with the risk of developing HCC. HCC developed in three of 182 (1.6%) patients in the F0 + 1 + 2 group, and four of 50 (8.0%) in the F3 + 4 group. The cumulative incidence of HCC in the former group was found to be significantly lower than in the F3 + 4 group (log rank test P = 0.0224). The presence of atypical hepatocytes among IR of hepatocytes in the F3 + 4 group resulted in a higher cumulative incidence of HCC, and was significantly correlated with risk of HCC development (RR = 20.748, 95%CI: 1.335-322.5, P = 0.0303). Atypical hepatocytes among the histopathological findings of type C liver disease may be an important risk factor for HCC development along with progression of liver fibrosis.

To identify search terms, we developed 3 terminology groups for case definitions: 1) spinal pain of unknown origin, 2) spinal syndromes, and 3) spinal pathology. We used a comprehensive strategy to search PubMed for meta-analyses and systematic reviews of case-control studies, cohort studies, and randomized controlled trials for risk and prognostic factors and cross-sectional studies describing associations and comorbidities. Of 3,453 candidate papers, 145 met study criteria and were included in this review. Risk factors were reported for group 1: non-specific low back pain (smoking, overweight/obesity, negative recovery expectations), non-specific neck pain (high job demands, monotonous work); group 2: degenerative spinal disease (workers' compensation claim, degenerative scoliosis), and group 3: spinal tuberculosis (age, imprisonment, previous history of tuberculosis), spinal cord injury (age, accidental injury), vertebral fracture from osteoporosis (type 1 diabetes, certain medications, smoking), and neural tube defects (folic acid deficit, anti-convulsant medications, chlorine, influenza, maternal obesity). A range of comorbidities was identified for spinal disorders. Many associated factors for common spinal disorders identified in this study are modifiable. The most common spinal disorders are co-morbid with general health conditions, but there is a lack of clarity in the literature differentiating which conditions are merely comorbid versus ones that are risk factors. Modifiable risk factors present opportunities for policy, research, and public health prevention efforts on both the individual patient and community levels. Further research into prevention interventions for spinal disorders is needed to address this gap in the literature.

To determine whether whole-brain, event-related fMRI can distinguish healthy older adults with known Alzheimer disease (AD) risk factors (family history, APOE epsilon4) from controls using a semantic memory task involving discrimination of famous from unfamiliar names. Sixty-nine cognitively asymptomatic adults were divided into 3 groups (n = 23 each) based on AD risk: 1) no family history, no epsilon4 allele (control [CON]); 2) family history, no epsilon4 allele (FH); and 3) family history and epsilon4 allele (FH+epsilon4). Separate hemodynamic response functions were extracted for famous and unfamiliar names using deconvolution analysis (correct trials only). Cognitively intact older adults with AD risk factors (FH and FH+epsilon4) exhibited greater activation in recognizing famous relative to unfamiliar names than a group without risk factors (CON), especially in the bilateral posterior cingulate/precuneus, bilateral temporoparietal junction, and bilateral prefrontal cortex. The increased activation was more apparent in the FH+epsilon4 than in the FH group. Unlike the 2 at-risk groups, the control group demonstrated greater activation for unfamiliar than familiar names, predominately in the supplementary motor area, bilateral precentral, left inferior frontal, right insula, precuneus, and angular gyrus. These results could not be attributed to differences in demographic variables, cerebral atrophy, episodic memory performance, global cognitive functioning, activities of daily living, or depression. Results demonstrate that a low-effort, high-accuracy semantic memory activation task is sensitive to Alzheimer disease risk factors in a dose-related manner. This increased activation in at-risk individuals may reflect a compensatory brain response to support task performance in otherwise asymptomatic older adults.

Background The effects of systolic blood pressure (SBP), serum total cholesterol (TC), fasting plasma glucose (FPG), and body mass index (BMI) on the risk of cardiovascular diseases (CVD) have been established in epidemiological studies, but consistent estimates of effect sizes by age and sex are not available. Methods We reviewed large cohort pooling projects, evaluating effects of baseline or usual exposure to metabolic risks on ischemic heart disease (IHD), hypertensive heart disease (HHD), stroke, diabetes, and, as relevant selected other CVDs, after adjusting for important confounders. We pooled all data to estimate relative risks (RRs) for each risk factor and examined effect modification by age or other factors, using random effects models. Results Across all risk factors, an average of 123 cohorts provided data on 1.4 million individuals and 52,000 CVD events. Each metabolic risk factor was robustly related to CVD. At the baseline age of 55–64 years, the RR for 10 mmHg higher SBP was largest for HHD (2.16; 95% CI 2.09–2.24), followed by effects on both stroke subtypes (1.66; 1.39–1.98 for hemorrhagic stroke and 1.63; 1.57–1.69 for ischemic stroke). In the same age group, RRs for 1 mmol/L higher TC were 1.44 (1.29–1.61) for IHD and 1.20 (1.15–1.25) for ischemic stroke. The RRs for 5 kg/m2 higher BMI for ages 55–64 ranged from 2.32 (2.04–2.63) for diabetes, to 1.44 (1.40–1.48) for IHD. For 1 mmol/L higher FPG, RRs in this age group were 1.18 (1.08–1.29) for IHD and 1.14 (1.01–1.29) for total stroke. For all risk factors, proportional effects declined with age, were generally consistent by sex, and differed by region in only a few age groups for certain risk factor-disease pairs. Conclusion Our results provide robust, comparable and precise estimates of the effects of major metabolic risk factors on CVD and diabetes by age group. PMID:23935815

Underage drinking on saturday nights, sociodemographic and environmental risk factors: a cross-sectional study

PubMed Central

2011-01-01

Background Excessive alcohol consumption in underage people is a rising phenomenon. A major proportion of the disease burden and deaths of young people in developed nations is attributable to alcohol abuse. The aim of this study was to investigate social, demographic and environmental factors that may raise the risk of Saturday night drinking and binge drinking among Italian school students. Methods The study was conducted on a sample of 845 Italian underage school students, by means of an anonymous, self-test questionnaire. Multivariate logistic regression was applied to identify independent risk factors for alcohol drinking and binge drinking. Ordered logistic regression was used to identify independent risk factors for harmful drinking patterns. Results The independent variables that confer a higher risk of drinking in underage students are older age classes, male sex, returning home after midnight, belonging to a group with little respect for the rules, or to a group where young people are not seen as leaders. The higher the perception of alcohol consumption by the group, the higher the risk. Spending time in bars or discos coincides with a two-fold or four-fold increase, respectively, in the risk of alcohol consumption. Conclusion Our findings show that certain environmental and social risk factors are associated with underage drinking. The most important role for preventing young people's exposure to these factors lies with the family, because only parents can exert the necessary control and provide a barrier against potentially harmful situations.

Bile duct injury after ablation of malignant liver tumors (MLTs) was not unusual and should be avoided. However, few studies have focused on evaluating the risk factors for intrahepatic bile duct injury. To evaluate the risk factors for intrahepatic bile duct injury after ablation of MLTs and to evaluate the minimum safe distance for ablating tumors abutting bile ducts. Sixty-five patients with intrahepatic bile duct injury after ablation of MLTs, and 65 controls were recruited. Risk factors for intrahepatic bile duct injury were analyzed. Tumor location was recorded as ≤5 mm (group A), 5-10 mm (group B), and >10 mm (group C) from the right/left main duct or segmental bile duct. Ascites history (P < 0.001), TACE treatment history (P = 0.025), intrahepatic bile duct dilatation before ablation (P < 0.001), and tumor location (P = 0.000) were identified as significant risk factors for intrahepatic bile duct injury. Significant differences in the risk of intrahepatic bile duct injury were found between groups B and C (P = 0.000), but not between groups A and B (P = 0.751). Ascites history (P = 0.002) and tumor location (P < 0.001) were independent predictors with the OR (95 % confidence interval) of 39.31(3.95-391.69) and 16.56 (5.87-46.71), respectively. Bile duct injury after ablation of MLTs was the result of local treatment-related factors combined with the patients' general condition. The minimum safe distance for ablation of tumor abutting a bile duct was 10 mm.

We discuss the analytic and practical considerations in a large case-control study that had two control groups; the first control group consisting of partners of patients and the second obtained by random digit dialling (RDD). As an example of the evaluation of a general lifestyle factor, we present body mass index (BMI). Both control groups had lower BMIs than the patients. The distribution in the partner controls was closer to that of the patients, likely due to similar lifestyles. A statistical approach was used to pool the results of both analyses, wherein partners were analyzed with a matched analysis, while RDDs were analyzed without matching. Even with a matched analysis, the odds ratio with partner controls remained closer to unity than with RDD controls, which is probably due to unmeasured confounders in the comparison with the random controls as well as intermediary factors. However, when studying injuries as a risk factor, the odds ratio remained higher with partner control subjects than with RRD control subjects, even after taking the matching into account. Finally we used factor V Leiden as an example of a genetic risk factor. The frequencies of factor V Leiden were identical in both control groups, indicating that for the analyses of this genetic risk factor the two control groups could be combined in a single unmatched analysis. In conclusion, the effect measures with the two control groups were in the same direction, and of the same order of magnitude. Moreover, it was not always the same control group that produced the higher or lower estimates, and a matched analysis did not remedy the differences. Our experience with the intricacies of dealing with two control groups may be useful to others when thinking about an optimal research design or the best statistical approach.

Studies of racial/ethnic variations in stroke rarely consider the South Asian population, one of the fastest growing sub-groups in the United States. This study compared risk factors for stroke among South Asians with those for whites, African-Americans, and Hispanics. Data on 3290 stroke patients were analyzed to examine risk differences among the four racial/ethnic groups. Data on 3290 patients admitted to a regional stroke center were analyzed to examine risk differences for ischemic stroke (including subtypes of small and large vessel disease) among South Asians, whites, African Americans and Hispanics. South Asians were younger and had higher rates of diabetes mellitus, blood pressure, and fasting blood glucose levels than other race/ethnicities. Prevalence of diabetic and antiplatelet medication use, as well as the incidence of small-artery occlusion ischemic stroke was also higher among South Asians. South Asians were almost a decade younger and had comparable socioeconomic levels as whites; however, their stroke risk factors were comparable to that of African Americans and Hispanics. Observed differences in stroke may be explained by dietary and life style choices of South Asian-Americans, risk factors that are potentially modifiable. Future population and epidemiologic studies should consider growing ethnic minority groups in the examination of the nature, outcome, and medical care profiles of stroke.

Recurrent urinary tract infections are a common condition in women. The aim of this study is the evaluation of lower urinary tract dysfunctions that are risk factors for recurrent urinary tract infections in women. We conducted a case-control study in 49 women with recurrent urinary tract infections (rUTIs) and 49 control women without rUTIs, comparing the urinary symptoms and urodynamic data of both groups. The main significant differences between these groups were age (the women were older in the control group) and the value of abdominal pressure during voiding cystometry (this was higher in the group with rUTIs). After controlling age as a confounding factor, it was confirmed that the value of maximum abdominal pressure during voiding was the only factor to facilitate the rUTIs and the ideal cut-off was 28 cm H(2)O. Abdominal strength in the voiding phase constitutes a risk factor for recurrent urinary tract infections in women.

This study assessed whether pregnancy-induced hypertension (PIH) affects the prevalence of cardiovascular disease (CVD) risk factors in later life among Japanese women. Study participants were 1,185 women (mean [SD] age, 46.5 [5.6] y; range, 38-73 y) aged 40 years or older who underwent a health checkup at a periodic health examination facility between January 2012 and December 2013 and had experienced giving birth. Questionnaires were sent to potential participants, and they were encouraged to provide their Maternal and Child Health Handbook (handbook). We recruited 101 women with a history of PIH (PIH group) and 1,084 women with uncomplicated pregnancy at delivery (control group). Groupings were based on information from the handbook. We assessed the association between PIH and CVD in later life among Japanese women by focusing on hypertension, diabetes mellitus, and dyslipidemia as risk factors for CVD. Odds ratios (ORs) for the use of antihypertensive, diabetes mellitus, and dyslipidemic medications in the PIH group were determined. Women with PIH had increased risk of antihypertensive medication use compared with women without PIH (2.9% vs 13.9%; OR, 4.28; 95% CI, 2.14-8.57). Triglycerides were significantly higher and high-density lipoprotein cholesterol was significantly lower in the PIH group than in the control group. The OR for dyslipidemic medication use in the PIH group relative to the control group was 3.20 (95% CI, 1.42-7.22). Our findings suggest that a history of PIH may be associated with an increased risk of hypertension (a risk factor for CVD) in later life among Japanese women.

Previous research demonstrates an inverse association between age and cardiovascular disease (CVD) biomarkers with cognitive function; however, little is known about the combined associations of CVD risk factors and cognitive function with all-cause mortality in an older adult population, which was the purpose of this study. Data from the 1999-2002 NHANES were used (N=2,097; 60+yrs), with mortality follow-up through 2011. Evaluated individual biomarkers included mean arterial pressure (MAP), high-sensitivity C-reactive protein (CRP), HDL-C, total cholesterol (TC), A1C, and measured body mass index (BMI). Cognitive function was assessed using the Digit Symbol Substitution Test (DSST). Further, 4 groups were created based on CVD risk and cognitive function. Group 1: high cognitive function and low CVD risk; Group 2: high cognitive function and high CVD risk; Group 3: low cognitive function and low CVD risk; Group 4: low cognitive function and high CVD risk. An inverse relationship was observed where those with more CVD risk factors had a lower (worse) cognitive function score. Compared to those in Group 1, only those in Group 3 and 4 had an increase mortality risk. Copyright © 2016 Elsevier Inc. All rights reserved.

Bovine TB (bTB) is endemic in Irish cattle and has eluded eradication despite considerable expenditure, amid debate over the relative roles of badgers and cattle in disease transmission. Using a comprehensive dataset from Northern Ireland (>10,000 km(2); 29,513 cattle herds), we investigated interactions between host populations in one of the first large-scale risk factor analyses for new herd breakdowns to combine data on both species. Cattle risk factors (movements, international imports, bTB history, neighbours with bTB) were more strongly associated with herd risk than area-level measures of badger social group density, habitat suitability or persecution (sett disturbance). Highest risks were in areas of high badger social group density and high rates of persecution, potentially representing both responsive persecution of badgers in high cattle risk areas and effects of persecution on cattle bTB risk through badger social group disruption. Average badger persecution was associated with reduced cattle bTB risk (compared with high persecution areas), so persecution may contribute towards sustaining bTB hotspots; findings with important implications for existing and planned disease control programmes.

Subclinical hypothyroidism is suggested to increase cardiovascular risk. No previous study compared the effect of any fibrate on plasma levels of lipids and other cardiovascular risk factors in patients with different thyroid function status. The study included three age-, weight- and lipid-matched groups of women with mixed dyslipidemia in different thyroid function status: patients with untreated subclinical hypothyroidism (group 1, n = 18), women with treated hypothyroidism (group 2, n = 15), and subjects without thyroid disorders (group 3, n = 19). Plasma lipids, glucose homeostasis markers, as well as plasma levels of uric acid, high-sensitivity C-reactive protein (hsCRP), homocysteine, and fibrinogen were determined before and after 12 weeks of fenofibrate therapy. Despite similar plasma lipid levels, mixed dyslipidemic patients with untreated hypothyroidism had decreased insulin sensitivity, as well as higher circulating levels of uric acid, hsCRP, homocysteine, and fibrinogen in comparison with the other groups. The effect of fenofibrate on plasma lipids and, with the exception of homocysteine, on circulating levels of all investigated risk factors was stronger in patients from groups 2 and 3 than in patients from group 1. The obtained results indicate that the effect of fenofibrate on plasma lipids and circulating levels of cardiovascular risk factors is partially related to thyroid function. They also suggest that to improve the strength of fibrate action in dyslipidemic patients with subclinical hypothyroidism, they should be administered together with L-thyroxine. © 2014 John Wiley & Sons Ltd.

Recently, acquired as well as genetic prothrombotic factors are associated with thrombotic events. These factors have also been related to conditions of uteroplacental insufficiency such as pre-eclampsia, HELLP syndrome and severe intrauterine growth restriction (IUGR). The aim of this study was to determine whether elevated factor VIII levels are associated with uteroplacental insufficiency, in particular pre-eclampsia, HELLP syndrome or pregnancy-induced hypertension and intrauterine growth retardation. Plasma samples of 75 women with a history of pregnancy complicated by pre-eclampsia, HELLP syndrome, pregnancy induced hypertension or intrauterine growth restriction were tested for factor VIII:C (FVIII:C) levels at a minimum of 10 weeks post-partum. Laboratory results were compared to factor VIII:C levels found in a healthy control group of 272 women. Mean factor VIII:C levels were similar at 123 IU/dl in both the patient group and the controls. In a logistic regression model, after adjusting for age and blood group, no effect of factor VIII:C levels on the risk of pregnancy complications was observed, with the exception of IUGR with (OR 2.9, CI 1.0-8.7) or without hypertension (OR 2.0, CI 0.7-6.4). If the elevated level of factor VIII would be the sole factor responsible for the increased risk observed, one would expect to find an effect of blood group on risk as well (blood group being an important determinant of FVIII:C). While no such effect could be shown a causal relationship between elevated levels of factor VIII and conditions of uteroplacental insufficiency such as pre-eclampsia, HELLP syndrome, pregnancy-induced hypertension and IUGR is not very likely.

Patients with rheumatic disease are at risk for infections. Evaluating antitumour necrosis factor (anti-TNF) drug-associated risk of infections requires justification of baseline risk in the population at high risk of infection. We examined the incidence of active tuberculosis (TB) and its risk factors in patients with rheumatic disease started with anti-TNF-α therapy or with existing disease-modifying antirheumatic drug (DMARD) therapy. A retrospective cohort study of anti-TNF-α therapy new users (anti-TNF-α group) and those starting with a DMARD after the failure of at least one other DMARD or who had added to existing DMARD treatment (DMARD group) for rheumatic disease in the largest medical setting in Taiwan from 1 January 2005 through 31 November 2013 was conducted to determine relative risk of TB between patient groups. Patients in the DMARD group were stratified into "mild" and "severe" disease severity as proxies for low and high background risk of infection. A total of 3640 patients were enrolled (anti-TNF: 955; DMARD: 2685). The incidence of TB was 903.9/100 000 patient-years for anti-TNF-α new users and 391.7/100 000 patient-years for DMARD switchers. In Cox regression model, adjusted HR for TB in the anti-TNF-α group was higher than for the entire DMARD group (aHR, 2.41; 95% confidence interval [CI], 1.2-4.85), subgroup with mild disease (2.91; 1.31-6.47) and subgroup with severe disease (1.65; 0.68-4.03). Significant independent risk factors for TB were being male, age ≥60 years, history of respiratory disease, glucocorticoids dose >7.5 mg/d and living in a TB-prevalent region. Anti-TNF-α therapy was independently associated with increased risk of TB in patients with mild disease, but it was not significantly correlated in patients with severe disease after adjusting for confounders. © 2017 John Wiley & Sons Ltd.

To investigate the slope of linear regression of postevacuation serum hCG as an independent risk factor for postmolar gestational trophoblastic neoplasia (GTN). Multicenter retrospective cohort study. Academic referral health care centers. All subjects with confirmed hydatidiform mole and at least four measurements of β-hCG titer. None. Type and magnitude of the relationship between the slope of linear regression of β-hCG as a new risk factor and GTN using Bayesian logistic regression with penalized log-likelihood estimation. Among the high-risk and low-risk molar pregnancy cases, 11 (18.6%) and 19 cases (13.3%) had GTN, respectively. No significant relationship was found between the components of a high-risk pregnancy and GTN. The β-hCG return slope was higher in the spontaneous cure group. However, the initial level of this hormone in the first measurement was higher in the GTN group compared with in the spontaneous recovery group. The average time for diagnosing GTN in the high-risk molar pregnancy group was 2 weeks less than that of the low-risk molar pregnancy group. In addition to slope of linear regression of β-hCG (odds ratio [OR], 12.74, confidence interval [CI], 5.42-29.2), abortion history (OR, 2.53; 95% CI, 1.27-5.04) and large uterine height for gestational age (OR, 1.26; CI, 1.04-1.54) had the maximum effects on GTN outcome, respectively. The slope of linear regression of β-hCG was introduced as an independent risk factor, which could be used for clinical decision making based on records of β-hCG titer and subsequent prevention program.

This triple-masked controlled trial aimed to assess the effects of vitamin D supplementation on insulin resistance and cardiometabolic risk factors in obese children and adolescents. The study comprised 50 participants, aged 10 to 16 years, who were randomly assigned into two groups of equal number. In this 12-week trial, one group received oral vitamin D (300,000 IU) and the other group received placebo. Cardiometabolic risk factors, insulin resistance, and a continuous value of metabolic syndrome (cMetS) were determined. Statistical analysis was conducted after adjustment for covariate interactions. Overall, 21 patients in the vitamin D group and 22 in the placebo group completed the trial. No significant difference was observed in the baseline characteristics of the two groups. After the trial, in the vitamin D group, serum insulin and triglyceride concentrations, as well as HOM -IR and C-MetS decreased significantly, both when compared with the baseline and with the placebo group. No significant difference was observed when comparing total cholesterol, LDL-C, HDL-C, fasting blood glucose, and blood pressure. The present findings support the favorable effects of vitamin D supplementation on reducing insulin resistance and cardiometabolic risk factors in obese children.

Although work related risk factors associated with Cardiovascular Diseases (CD) have been well researched, there is no detailed knowledge regarding disparate occupational groups each with a different risk exposition. Therefore, two occupational groups (chefs and office workers) were compared with a focus on nutritional and psychosocial factors. Two groups of subjects were tested for work and diet-related risks of CD (45 chefs and 48 office workers). The groups matched both for gender (male) and age (30 to 45 years). The study included a medical check-up, bioelectrical impedance analysis as well as an evaluation of questionnaires on health, nutritional behaviour and coping capacity. In addition, volunteers were required to compile a 7-day-dietary-record and collect their urine 24 h prior to their check-up. Blood samples drawn were analysed for glucose and lipid metabolism, homocysteine, vitamin B12, folic acid; C-reactive protein, uric acid, red blood cell fatty acids, plant sterols, antioxidative capacity and oxidative stress. On average, the chefs showed one risk factor more compared to the office workers. The most frequent risk factors in both groups included overweight/obesity (chef group [CG]: 62.2%; office group [OG]: 58.3%) and elevated TC (CG: 62.2%; OG: 43.8%]. Moreover, although the chefs often had higher CRP-concentrations (40.0%), more office workers suffered from hypertension (37.5%).Chefs showed significant higher concentrations of saturated fatty acids and oleic acid, whereas docosahexaenoic acid, Omega-6- and trans fatty acids were found more frequently in the red blood cell membranes of office workers. While there were no significant differences in analysed plant sterols between the two occupational groups, 7,8-dihydro-8-oxo-2'-deoxyguanosine was significantly increased in office workers.Concerning the work-related psychosocial factors, the chefs were characterised by a stronger subjective importance of work, a greater degree of professional aspiration and enhanced efforts at perfectionism at their workplace. The chefs in the study bear a higher risk of CD compared to the office-workers. Although, CD is not exclusively a result of workplace-conditions, study results show that work-related influences can not be ignored. Thus, prevention of CD may be an important task attributable to occupational physicians.

Suicide rates vary widely across nations and ethnic groups. This study aims to explore potential factors contributing to inter-ethnic differences in suicide rates. Study subjects came from a case-control psychological autopsy study conducted in Taiwan, including 116 consecutive suicides from two aboriginal groups and Taiwanese Han; 113 of them each matched with two living controls. Gender-, age- and method-specific suicide rates, population attributable fraction (PAF) of suicide for five major risk factors, help-seeking before suicide and emergency medical aid after suicide were compared between the three ethnic groups. One aboriginal group (the Atayal) had significantly higher adjusted rate ratios (RR) of suicide than the other aboriginal group (the Ami) [RR 0.20, 95% confidence intervals (CI) 0.12-0.34] and the Han (RR 0.26, 95% CI 0.16-0.40). Such differences can be explained by higher PAFs of suicide for three major risk factors (substance dependence, PAF 47.6%, 95% CI 25.5-64.2; emotionally unstable personality disorder, PAF 52.7%, 95% CI 32.8-69.0; family history of suicidal behaviour, PAF 43.5%, 95% CI 23.2-60.2) in this group than in the other two groups. This higher suicide rate was substantially reduced from 68.2/100 000 per year to 9.1/100 000 per year, comparable with the other two groups, after stepwise removal of the effects of these three risk factors. Suicide rates by self-poisoning were also significantly higher in this group than in the other two groups. Higher rates of specific risk factors and use of highly lethal pesticides for suicide contributed to the higher suicide rate in one ethnic group in Taiwan. These findings have implications for developing ethnicity-relevant suicide prevention strategies.

There are few studies about risk factors for poor outcomes from multi-level lumbar posterolateral fusion limited to three or four level lumbar posterolateral fusions. The purpose of this study was to analyze the outcomes of multi-level lumbar posterolateral fusion and to search for possible risk factors for poor surgical outcomes. We retrospectively analyzed 37 consecutive patients who underwent multi-level lumbar or lumbosacral posterolateral fusion with posterior instrumentation. The outcomes were deemed either 'good' or 'bad' based on clinical and radiological results. Many demographic and radiological factors were analyzed to examine potential risk factors for poor outcomes. Student t-test, Fisher exact test, and the chi-square test were used based on the nature of the variables. Multiple logistic regression analysis was used to exclude confounding factors. Twenty cases showed a good outcome (group A, 54.1%) and 17 cases showed a bad outcome (group B, 45.9%). The overall fusion rate was 70.3%. The revision procedures (group A: 1/20, 5.0%; group B: 4/17, 23.5%), proximal fusion to L2 (group A: 5/20, 25.0%; group B: 10/17, 58.8%), and severity of stenosis (group A: 12/19, 63.3%; group B: 3/11, 27.3%) were adopted as possible related factors to the outcome in univariate analysis. Multiple logistic regression analysis revealed that only the proximal fusion level (superior instrumented vertebra, SIV) was a significant risk factor. The cases in which SIV was L2 showed inferior outcomes than those in which SIV was L3. The odds ratio was 6.562 (95% confidence interval, 1.259 to 34.203). The overall outcome of multi-level lumbar or lumbosacral posterolateral fusion was not as high as we had hoped it would be. Whether the SIV was L2 or L3 was the only significant risk factor identified for poor outcomes in multi-level lumbar or lumbosacral posterolateral fusion in the current study. Thus, the authors recommend that proximal fusion levels be carefully determined when multi-level lumbar fusions are considered.

In this study we aimed to identify the role of the body mass index (BMI), wrist index and hand anthropometric measures as risk factors for carpal tunnel syndrome (CTS) in both genders. Based on clinical and electrophysiologic diagnostic criteria, 154 female and 44 male CTS patients, as well as 150 female and 44 male age-matched control subjects, were selected. BMI, wrist index, hand shape index, digit index and hand length/height ratio were compared between the CTS patients and the control subjects for each gender separately. Mean BMI was found to be a significant risk factor for CTS in both genders. The wrist index was found to be higher in female (P < 0.001) and in male (P = 0.034) CTS groups than in the respective control groups. Logistic regression analysis revealed the wrist index to be an independent risk factor in females, but not in males. Shape and digit indices were significantly higher in female CTS patients than in corresponding control subjects, and regression analysis showed the shape and digit indices to be independent risk factors for CTS. In the male CTS group, the shape and digit indices did not significantly differ from their controls. Differences in the hand length/height ratio were not statistically significant in female and male CTS patients compared to their controls and it was not found to be an independent risk factor for CTS. Our study confirmed BMI as an independent risk factor for CTS in both genders. Hand and wrist anthropometrics were found to be independent risk factors for CTS in females, but not in males.

The association of molecular characteristics with prognosis has been reported, but not their relationship with each other and their impact in the context of known clinical risk factors. In this study, data of 1249 consecutive intent-to-treat-neuroblastoma patients with more than 1 year follow-up were examined by multivariate analysis using loglinear and Cox proportional hazard regression models on a stage-related basis (stages 1-3: 600, 4S: 116, 4: 533). In a first step, risk factors were identified from 18 selected clinical variables, and risk groups defined. The second step investigated whether molecular characteristics (MYCN, LOH 1p, del 1p, CD44, N-ras, NGF-R, bcl-2, APO-1 (CD95)) contributed additional prognostic information to the model. The loglinear model demonstrated several interactions between clinical factors. By the Cox regression model, seven independent clinical risk factors were found for stages 1-3, seven for stage 4 and two for stage 4S. By subsequent introduction of all molecular variables, MYCN amplification only added significant prognostic information to the clinical factors in localised and stage 4 neuroblastoma. The models allowed the definition of risk groups for stages 1-3 patients by age (e beta = 5.09) and MYCN (e beta = 4.26), for stage 4 by MYCN (e beta = 2.78) and number of symptoms (e beta = 2.44) and for stage 4S by platelet count (e beta = 3.91) and general condition (e beta = 2.99). Molecular factors and in particular MYCN contribute significantly to risk estimation. In conjunction with clinical factors, they are powerful tools to define risk groups in neuroblastoma.

Violence risk assessment and management are key tasks in mental health services and should be guided by validated instruments covering both risk and protective factors. This article is part of an international effort to validate the Structured Assessment of Protective Factors (SAPROF) for violence. The SAPROF, Historical, Clinical, Risk Management-20 (HCR-20) and the Psychopathy Checklist-Screening Version (PCL-SV) were administered in a sample of 261 patients in U.K. forensic, general inpatient, and community mental health settings. There was significant variation between these groups on SAPROF scores with fewer protective factors in the forensic group. The prospective validity of the SAPROF for nonviolence in the general inpatient and community samples was moderate (area under the curve [AUC] = .60). Adoption of the SAPROF or similar instruments as a supplement to risk-focused assessments has the potential to improve awareness of protective factors and enhance therapeutic engagement in a range of mental health services.

We examined the health of a control group (18-81years) in our aging study, which is similar to control groups used in other neuroimaging studies. The current study was motivated by our previous results showing that one third of the elder control group had moderate to severe white matter hyperintensities and/or cortical volume loss which correlated with poor performance on memory tasks. Therefore, we predicted that cardiovascular risk factors (e.g., hypertension, high cholesterol) within the control group would account for significant variance on working memory task performance. Fifty-five participants completed 4 verbal and spatial working memory tasks, neuropsychological exams, diffusion tensor imaging (DTI), and blood tests to assess vascular risk. In addition to using a repeated measures ANOVA design, a cluster analysis was applied to the vascular risk measures as a data reduction step to characterize relationships between conjoint risk factors. The cluster groupings were used to predict working memory performance. The results show that higher levels of systolic blood pressure were associated with: 1) poor spatial working memory accuracy; and 2) lower fractional anisotropy (FA) values in multiple brain regions. In contrast, higher levels of total cholesterol corresponded with increased accuracy in verbal working memory. An association between lower FA values and higher cholesterol levels were identified in different brain regions from those associated with systolic blood pressure. The conjoint risk analysis revealed that Risk Cluster Group 3 (the group with the greatest number of risk factors) displayed: 1) the poorest performance on the spatial working memory tasks; 2) the longest reaction times across both spatial and verbal memory tasks; and 3) the lowest FA values across widespread brain regions. Our results confirm that a considerable range of vascular risk factors are present in a typical control group, even in younger individuals, which have robust effects on brain anatomy and function. These results present a new challenge to neuroimaging studies both for defining a cohort from which to characterize 'normative' brain circuitry and for establishing a control group to compare with other clinical populations. © 2013.

Not only are childhood onset offenders at high risk of becoming serious persistent offenders, they are also at high risk of becoming victimized themselves. Furthermore, studies in the general population suggest that a combined perpetrator-victim group can be distinguished from a perpetrator-only and a victim-only group on individual and family risk factors. The current study investigated the co-occurrence of offending and victimization among first-time arrestees and the 2-year predictive value of previously found clusters of dynamic risk factors of offending. Childhood first-time arrestees ( N = 308; M age = 10.3, SD = 1.45) were clustered into three groups based on dynamic risk factors of offending in the individual, peer, school, and family domains: a pervasive high, an externalizing intermediate, and a low problem group. Police records and self-report data on re-offending and victimization of these children were collected over a 2-year follow-up period. Compared with the low problem group, the prevalence of re-offending was higher in both the externalizing intermediate group and the pervasive high group. The pervasive high group was most likely to display co-occurring future antisocial behavior and victimization. These findings emphasize that attention should be paid to victimization in addition to future antisocial behavior, especially if additional internalizing and family problems are present. Furthermore, the differences in re-offending and victimization between subgroups of childhood onset offenders stress the need for specific interventions tailored to the risk profile of a child.

To agree a draft pressure ulcer risk factor Minimum Data Set to underpin the development of a new evidenced-based Risk Assessment Framework. A recent systematic review identified the need for a pressure ulcer risk factor Minimum Data Set and development and validation of an evidenced-based pressure ulcer Risk Assessment Framework. This was undertaken through the Pressure UlceR Programme Of reSEarch (RP-PG-0407-10056), funded by the National Institute for Health Research and incorporates five phases. This article reports phase two, a consensus study. Consensus study. A modified nominal group technique based on the Research and Development/University of California at Los Angeles appropriateness method. This incorporated an expert group, review of the evidence and the views of a Patient and Public Involvement service user group. Data were collected December 2010-December 2011. The risk factors and assessment items of the Minimum Data Set (including immobility, pressure ulcer and skin status, perfusion, diabetes, skin moisture, sensory perception and nutrition) were agreed. In addition, a draft Risk Assessment Framework incorporating all Minimum Data Set items was developed, comprising a two stage assessment process (screening and detailed full assessment) and decision pathways. The draft Risk Assessment Framework will undergo further design and pre-testing with clinical nurses to assess and improve its usability. It will then be evaluated in clinical practice to assess its validity and reliability. The Minimum Data Set could be used in future for large scale risk factor studies informing refinement of the Risk Assessment Framework. © 2014 The Authors.

Avascular necrosis of the femoral head is an illness with a controversial etiology, the trigger event being the suppression of blood flow to the femoral head. The disease affects mostly young adults within their third and fifth decade, the majority of the patients being men. The main risk factors are trauma, chronic alcohol consumption, smoking, corticotherapy. The main goal of our study is to describe the morphometric changes found in the bone tissue of patients diagnosed with avascular necrosis of the femoral head, with different risk factors, by comparing the area of bone trabeculae inside the area of necrosis with that from the adjacent viable tissue. The morphometric study used biological material from 16 patients with ages between 29 and 57 years, who underwent surgery for avascular necrosis of the femoral head. They were admitted in the Orthopedics Department at the Emergency County Hospital in Craiova between 2010 and 2011 and were split into four groups. Group I presented trauma as the main risk factor, Group II had corticotherapy as the defining risk factor, Group III presented chronic alcohol consumption and Group IV was represented by the patients who smoked and exhibited chronic alcohol consumption. There was not a significant statistical difference between the areas of bone trabeculae of the four groups when we compared viable bone tissue to the necrotized one. Knowing the risk factors of the avascular necrosis of the femoral head is critical to the management of the disease, because diagnosing it in an early stage is a necessity for obtaining a good result for conservative treatment.

This study assesses the effects of obesity, physical inactivity and smoking on life expectancy (LE) differences between educational groups in five European countries in the early 2000s. We estimate the contribution of risk factors on LE differences between educational groups using the observed risk factor distributions and under a hypothetically more optimal risk factor distribution. Data on risk factor prevalence were obtained from the Survey of Health, Ageing and Retirement in Europe study, and data on mortality from census-linked data sets for the age between 50 and 79 according to sex and education. Substantial differences in LE of up to 2.8 years emerged between men with a low and a high level of education in Denmark, Austria and France, and smaller differences among men in Italy and Spain. The educational differences in LE were not as large among women. The largest potential for reducing educational differences was in Denmark (25% among men and 41% among women) and Italy (14% among men). The magnitude of the effect of unhealthy behaviours on educational differences in LE varied between countries. LE among those with a low or medium level of education could increase in some European countries if the behavioural risk factor distributions were similar to those observed among the highly educated.

The evolution of autistic disorders in children depends on many factors, like concomitance of the other diseases, which can escalate the autistic symptoms. One of those groups are allergic diseases, which have one of the highest prevalence rates in children. The aim of this analysis was to determine the frequency of asthma and allergy in children with autism in comparison to controls and the risk factors of allergic diseases and asthma in both groups. Study population included 96 cases diagnosed with childhood or atypical autism and 192 controls matched individually by year of birth, gender and physician's practice. The analysis was performed in each group separately giving possibility to compare the results between study groups. The frequency of asthma and allergic diseases in both groups has not revealed any statistically significant differences. Children with autism have been affected by asthma in 5,2% and by allergy in 25,0%, controls in 4,7% and 21,9% respectively. All cases of asthma was diagnosed in boys, commonly allergy was also more frequent in boys than girls in both studied groups. However those differences was statistically insignificant. The father's allergy and asthma was revealed as a risk factor of allergy in children with autism. In controls additionally allergy or asthma diagnosed in mother or grandparent increased risk of allergy in children. Children with autism were affected by asthma and allergy with similar frequency like children without autistic disorders. Allergy in father was the risk factor of allergic diseases in children with autism.

2015-01-01

Background Noncommunicable diseases (NCDs) are the leading cause of death in low- and middle-income countries. Therefore, the surveillance of risk factors has become an issue of major importance for planning and implementation of preventive measures. Unfortunately, in these countries data on NCDs and their risk factors are limited. This also prevails in Suriname, a middle-income country of the Caribbean, with a multiethnic/multicultural population living in diverse residential areas. For these reasons, “The Suriname Health Study” was designed. Objective The main objective of this study is to estimate the prevalence of NCD risk factors, including metabolic syndrome, hypertension, and diabetes in Suriname. Differences between specific age groups, sexes, ethnic groups, and geographical areas will be emphasized. In addition, risk groups will be identified and targeted actions will be designed and evaluated. Methods In this study, several methodologies were combined. A stratified multistage cluster sample was used to select the participants of 6 ethnic groups (Hindustani, Creole, Javanese, Maroon, Chinese, Amerindians, and mixed) divided into 5 age groups (between 15 and 65 years) who live in urban/rural areas or the hinterland. A standardized World Health Organization STEPwise approach to surveillance questionnaire was adapted and used to obtain information about demographic characteristics, lifestyle, and risk factors. Physical examinations were performed to measure blood pressure, height, weight, and waist circumference. Biochemical analysis of collected blood samples evaluated the levels of glucose, high-density-lipoprotein cholesterol, total cholesterol, and triglycerides. Statistical analysis will be used to identify the burden of modifiable and unmodifiable risk factors in the aforementioned subgroups. Subsequently, tailor-made interventions will be prepared and their effects will be evaluated. Results The data as collected allow for national inference and valid analysis of the age, sex, and ethnicity subgroups in the Surinamese population. A publication of the basic survey results is anticipated in mid-2015. Secondary results on the effect of targeted lifestyle interventions are anticipated in late 2017. Conclusions Using the data collected in this study, the national prevalence of NCD risk factors will be approximated and described in a diverse population. This study is an entry point for formulating the structure of NCD prevention and surveillance. PMID:26085372

This study evaluates baseline patient characteristics and surgical parameters for risk factors of medical complications in ASD patients received posterior long level internal fixation. Analysis of consecutive patients who underwent posterior long-level instruction fixation for adult degenerative scoliosis (ADS) with a minimum of two year follow-up was performed. Pre-operative risk factors, intraoperative variables, peri-operative radiographic parameters, and surgical-related risk factors were collected to analyze the effect of risk factors on medical complications. Patients were separated into groups with and without medical complication. Then, complication group was further classified as major or minor medical complications. Potential risk factors were identified by univariate testing. Multivariate logistic regression was used to evaluate independent predictors of medical complications. One hundred and thirty-one ADS patients who underwent posterior long segment pedicle screws fixation were included. Total medical complication incidence was 25.2%, which included infection (12.2%), neurological (11.5%), cardiopulmonary (7.6%), gastrointestinal (6.1%), and renal (1.5%) complications. Overall, 7.6% of patients developed major medical complications, and 17.6% of patients developed minor medical complications. The radiographic parameters of pre-operative and last follow-up had no significant difference between the groups of medical complications and the major or minor medical complications subgroups. However, the incidence of cerebrospinal fluid leak (CFL) in patients who without medical complications was much lower than that with medical complications (18.4 vs. 42.4%, P = 0.005). Independent risk factors for development of medical complications included smoking (OR = 6.45, P = 0.012), heart disease (OR = 10.07, P = 0.012), fusion level (OR = 2.12, P = 0.001), and length of hospital stay (LOS) (OR = 2.11, P = 0.000). Independent risk factors for development of major medical complications were diabetes (OR 6.81, P = 0.047) and heart disease (OR = 5.99, P = 0.049). Except for the last follow-up, Oswestry Disability Index and visual analog scale of the patient experienced medical complications trend higher score; the clinical outcomes have no significant difference between the medical and major complications groups. Heart disease comorbidity is an independent risk factor for both medical and major medical complications. Smoking, fusion level, and LOS are independent risk factors for medical complication. Diabetes is the independent risk factors for major medical complications.

There are established variations in testicular cancer incidence between ethnic groups within countries. It is currently unclear whether the occurrence of cryptorchidism-a known risk factor for testicular cancer-follows similar patterns. In New Zealand Māori have unusually high rates of testicular cancer compared to individuals of European ancestry. We hypothesized that ethnic trends in the incidence of cryptorchidism would reflect those for testicular cancer in this setting. We followed 318,441 eligible male neonates born in New Zealand between 2000 and 2010 for the incidence of orchiopexy confirmed cryptorchidism and the incidence of known risk factors for cryptorchidism (low birth weight, short gestation, small size for gestational age) using routine maternity, hospitalization and mortality records. Logistic regression was used to calculate odds ratios for the presence of known risk factors for cryptorchidism by ethnic group. Poisson regression was used to calculate relative risk of cryptorchidism by ethnicity, adjusted for risk factors. Ethnic patterns of cryptorchidism incidence in New Zealand closely mirrored those previously observed for testicular cancer. Māori had higher rates of cryptorchidism than all other ethnic groups (adjusted RR 1.2 [95% CI 1.11-1.3]), with Pacific (0.89 [0.8-0.99]) and Asian groups (0.68 [0.59-0.79]) having the lowest rates (European/other, referent). Since the principal risk factors for cryptorchidism are present in utero, the results of the current study strengthen the likelihood that the ethnic patterning of testicular cancer is at least partly due to prenatal risk factors.

[Purpose] The aim was to investigate the effects of university students' smoking and aerobic exercise on metabolic syndrome risk factors. [Subjects and Methods] Twenty-three male students were randomly assigned to the following groups: exercise smoker (n=6), non-exercise smoker (n=6), exercise non-smoker (n=6), and non-exercise non-smoker (n=5). A basketball exercise program was conducted three times per week (70 minutes per session) for 8 weeks with exercise intensity set at 50-80% of heart rate reserve. After 8 weeks, the variables of risk factors for metabolic syndrome were obtained. [Results] Systolic blood pressure and diastolic blood pressure were significantly decreased in the exercise non-smoker group and significantly increased in the non-exercise smoker group. Waist circumference was significantly reduced in both exercise groups regardless of smoking and significantly increased in the non-exercise smoker group. Triglyceride, high-density lipoprotein-cholesterol, and fasting plasma glucose showed no differences between the groups. [Conclusion] Obesity and smoking management should be conducted together for students as well as for those with metabolic syndrome risk factors. It is recommended that more students participate in such programs, and exercise programs should be further developed and diversified to prevent metabolic syndrome and cardiovascular diseases.

Changes in the lipid profile have been suggested as a risk factor for developing ischemic stroke. Their role in intra-cerebral hemorrhage, however, is not clear. The present study was designed to evaluate the lipid profile levels of patients who had experienced an acute stroke during the first 24-hour and to compare these levels in different patients suffering from the stroke, either hemorrhagic or ischemic, and healthy individuals. In this cross-sectional study, 258 consecutive patients with acute stroke admitted to the neurology department of our center during September 2006 and September 2007 were studied. As for the control group, 187 apparently healthy subjects living in the same community and matched for age and sex were selected. Lipid profile was measured and compared between the three groups. In the patients' group, 65 suffered from hemorrhagic stroke (group 1) and the other 193 had ischemic stroke (group 2). Except for TG values, there was no significant difference among the ischemic and hemorrhagic lipid profile. Age, cholesterol, and LDL influenced the risk of developing an ischemic stroke; TG was not reported as a risk factor or a protective one. While the comparison of data retrieved from patients suffering from hemorrhagic strokes with the controls, revealed LDL as the risk factor contributing to the development of ICH whereas TG was reported as a protective factor. It could be concluded that LDL level can be considered as a risk factor for both ischemic and hemorrhagic cerebral events.

Carotid intima-media thickness (CIMT) is an established predictor of cardiovascular disease and stroke. We aimed to identify the association between CIMT and blood glucose, as well as the risk factors associated with increased CIMT in a low-income Chinese population. Stroke-free and cardiovascular disease-free residents aged ≥45 years were recruited. B-mode ultrasonography was carried out to measure CIMT. There were 2,643 participants (71.0%) in the normal group, 549 (14.7%) in the impaired fasting glucose group and 533 (14.3%) in the diabetes mellitus group. The determinants of increased CIMT were older age; male sex; low education; hypertension; smoking; high levels of systolic blood pressure, fasting blood glucose and low-density lipoprotein cholesterol; and low levels of diastolic blood pressure, triglycerides and high-density lipoprotein cholesterol, after adjusting for covariates. Age and hypertension were the common risk factors for increased CIMT in all three groups. Furthermore, male sex, smoking and high low-density lipoprotein cholesterol level were positively associated with the mean CIMT in the normal group; high triglycerides levels were negatively associated with the mean CIMT in the impaired fasting glucose group; and alcohol consumption was an independent risk factor for mean CIMT in the diabetes mellitus group. Hypertension was the greatest risk factor for increased CIMT. These findings suggest that it is crucial to manage and control traditional risk factors in low-income populations in China in order to decelerate the recent dramatic increase in stroke incidence, and to reduce the burden of stroke. © 2017 The Authors.

To assess whether the dietary supplement (bromelain) has the potential to reduce plasma fibrinogen and other cardiovascular disease (CVD) risk factors in patients with diabetes. This randomized placebo controlled, double blind, parallel design, efficacy study was carried out in China and investigated the effect of 12 weeks of bromelain (1,050 mg/day) on plasma fibrinogen. This randomized controlled trial (RCT) recruited 68 Chinese diabetic patients [32 males and 36 females; Han origin, mean age of 61.26 years (standard deviation (SD), 12.62 years)] with at least one CVD risk factor. Patients were randomized into either bromelain or placebo group. While bromelain group received bromelain capsule, the placebo group received placebo capsule which consisted inert ingredient and has no treatment effect. Subjects were required to take 1,050 mg (3×350 mg) of either bromelain or starch-filled placebo capsules, two to be taken (2×350 mg) after breakfast and another (350 mg) after dinner, daily for 12 weeks. Plasma fibrinogen, CVD risk factors and anthropometric indicators were determined at baseline and at 12 weeks. The change in the fibrinogen level in the bromelain group at the end of the study showed a mean reduction of 0.13 g/L (standard deviation (SD) 0.86g/L) compared with the mean reduction of 0.36 g/L (SD 0.96 g/L) for the placebo group. However, there was no significant difference in the mean change in fibrinogen between the placebo and bromelain groups (mean difference=0.23g/L (SD 0.22 g/L), =0.291). Similarly, the difference in mean change in other CVD risk factors (blood lipids, blood pressure), blood glucose, C-reactive protein and anthropometric measures between the bromelain and placebo groups was also not statistically significant. Statistical differences in fibrinogen between bromelain and placebo groups before the trial despite randomization may have influenced the results of this study. This RCT failed to show a beneficial effect in reducing fibrinogen or influencing other selected CVD risk factors but suggests other avenues for subsequent research on bromelain.

The high prevalence of cardiovascular disease (CVD) in the Hispanic population of the United States, together with low rates of health insurance coverage, suggest a potential cardiovascular health crisis. The objective of Project HEART (Health Education Awareness Research Team) was to promote behavior changes to decrease CVD risk factors in a high-risk Hispanic border population. Project HEART took place from 2005 through 2008 as a randomized community trial with a community-based participatory research framework using promotores de salud (community health workers). A total of 328 participants with at least 1 CVD risk factor were selected by randomizing 10 US Census tracts in El Paso, Texas, to either the experimental or the control group. The experimental group (n = 192) was assigned to a series of 8 health classes using the Su Corazón, Su Vida curriculum. After 2 months of educational sessions, the group was followed for 2 months. The control group (n = 136) was given basic educational materials at baseline, and no other intervention was used. Main outcomes of interest included changes in health behaviors and clinical measures. Participants in the experimental group showed more awareness of CVD risk factors, more confidence in the control of these factors, and improved dietary habits (ie, lower salt and cholesterol intake, better weight-control practices) compared with the control group. Total cholesterol was 3% lower in the experimental than in the control participants, and nonhigh-density lipoprotein cholesterol and low-density lipoprotein cholesterol were both 5% lower. The HEART trial suggests that community health education using promotores de salud is a viable strategy for CVD risk reduction in a Hispanic border community.

Our goal was to determine the number of patients who achieve low-density lipoprotein cholesterol (LDL-c) targets according to new guidelines. Descriptive and transversal study of patients from a cardiovascular clinic. LDL-c was calculated and targets were established according the NCEP-ATP III. 1,811 patients (46% males, 54% females) were studied. 35% of these were high-risk patients (group 1: coronary risk > 20% at 10 years), 19% were intermediate-risk patients (group 2: coronary risk 10-20% at 10 years) and 46% were low-risk patients (group 3: coronary risk < 10% at 10 years). Overall, 58% of patients achieved target LDL-c levels, yet success rates were 26% among group 1 patients, 51% among group 2 patients, and 86% among group 3 patients (p = 0.001, for differences between groups). Statin treatment was significantly related to achieving target LDL-c levels in group 1 patients (OR = 1.7; 95% CI, 1.2-2.4; p = 0.007). In group 1.41% of patients had LDL-c levels > 130 mg/dl without receiving lipid-lowering drugs. Although an overall 58% patients achieve target LDL-C levels, only one of four high-risk patients have LDL-c levels < 100 mg/dl, and statin treatment is a determining factor to achieve this goal. These findings indicate that a more aggressive treatment with statins is needed in secondary prevention.

We conducted a comparative risk assessment analysis to estimate the cardiometabolic disease (CMD) mortality attributable to 11 dietary and 4 metabolic risk factors in 20 countries of the Middle East by age, sex and time. The national exposure distributions were obtained from a systematic search of multiple databases. Missing exposure data were estimated using a multilevel Bayesian hierarchical model. The aetiological effect of each risk factor on disease-specific mortality was obtained from clinical trials and observational studies. The number of disease-specific deaths was obtained from the 2010 Global Burden of Disease mortality database. Mortality due to each risk factor was determined using the population attributable fraction and total number of disease-specific deaths. Adult population in the Middle East by age, sex, country and time. Suboptimal diet was the leading risk factor for CMD mortality in 11 countries accounting for 48% (in Morocco) to 72% (in the United Arab Emirates) of CMD deaths. Non-optimal systolic blood pressure was the leading risk factor for CMD deaths in eight countries causing 45% (in Bahrain) to 68% (in Libya) of CMD deaths. Non-optimal body mass index and fasting plasma glucose were the third and fourth leading risk factors for CMD mortality in most countries. Among individual dietary factors, low intake of fruits accounted for 8% (in Jordan) to 21% (in Palestine) of CMD deaths and low intake of whole grains was responsible for 7% (in Palestine) to 22% (in the United Arab Emirates) of CMD deaths. Between 1990 and 2010, the CMD mortality attributable to most risk factors had decreased except for body mass index and trans-fatty acids. Our findings highlight key similarities and differences in the impact of the dietary and metabolic risk factors on CMD mortality in the countries of the Middle East and inform priorities for policy measures to prevent CMD.

Background While non-Hispanic Black populations tend to be disproportionately affected by adverse reproductive outcomes, Hispanic populations tend to demonstrate healthier birth outcomes, regardless of socioeconomic background. Little is known about birth outcomes for women who are both Black and Hispanic. We examined whether birth outcomes and risk factors for women who are both Black and Hispanic most closely resemble those of women who are only Black or Hispanic and also compared these outcomes to those for Whites. Methods Using the 2013 US natality files, we examined 2,970,315 singleton births to Black Hispanic, Hispanic, Black, and White mothers. We used logistic regression to calculate predicted probabilities of low birth weight (LBW), preterm birth (PTB), or small for gestational age (SGA). Race-stratified regression analysis was used to identify the factors that significantly predicted risk for each outcome for each racial/ethnic group. Results Black mothers had the highest prevalence and predicted probabilities of experiencing all three outcomes. Black Hispanic mothers were less likely than Black mothers and more likely than Hispanic mothers to experience each of the adverse outcomes. We also found support for racial variation in risk and protective factors for mothers in the different groups. Factors like age and education inconsistently predicted risk of experiencing the birth outcomes for all groups. Overall, Black Hispanic mothers had birth outcomes and risk factor profiles like Hispanic mothers, although they had sociodemographic characteristics and health behaviors like Black mothers. Conclusions Patterning of birth outcomes among Black Hispanic women suggest an intersection of risk and protective factors associated with their respective racial and ethnic identities. Additional information about sociodemographic context is needed to develop a more complete picture of how factors related to race and ethnic group membership influence Black Hispanic women’s birth outcomes.

Gastric cancer (GC) is the third leading cause of cancer death worldwide, and is divided histologically in diffuse gastric cancer (DGC) and intestinal gastric cancer (IGC). Multiple risk factors have been associated with GC in different populations. The objective was to analyze the risk factors associated to DGC and IGC in a population from the western region of Mexico. The DGC (n = 27) and IGC (n = 26) cases, each matched by age and sex with a control group, were analyzed. Diet and lifestyle data were obtained by a questionnaire. Statistical analysis was performed with the software SPSSv18. The association of risk was calculated in odds ratio (OR); a value of p < 0.05 was considered significant. In the DGC group, the factors with significant OR values were: consumption of pork OR: 3.4 (1.11-10.4; p =0.032), smoking OR: 4.7 (1.5-15.0; p =0.007), green vegetables OR: 0.16 (0.03-0.83; p =0.029) and fruit OR: 0.28 (0.08-0.88; p =0.029). In the IGC group, the consumption of canned sardines was a significant risk factor OR: 4.07 (1.25-13.24; p =0.019). This work is the first to analyze the risk factors associated with GC in a population from western Mexico.

The risk factors related to hepatitis C virus (HCV) infection showed geographic and temporal differences. We investigated HCV-related risk factors in Korea where intravenous drug use (IVDU) is uncommon. The HCV-related risk factors were investigated in a prospective, multicenter chronic HCV cohort (n = 711) using a standardized questionnaire in four university hospitals. The results were compared with those of 206 patients with chronic liver diseases not related to either of HCV or hepatitis B virus infection (comparison group). The IVDU was found in 3.9% and remote blood transfusion (≥ 20 yr ago) in 18.3% in HCV cohort group, while that in comparison group was in none and 5.3%, respectively. In a multivariate logistic analysis, transfusion in the remote past (odds ratio [OR], 2.99), needle stick injury (OR, 4.72), surgery (OR, 1.89), dental procedures (OR, 2.96), tattooing (OR, 2.07), and multiple sexual partners (2-3 persons; OR, 2.14, ≥ 4 persons; OR, 3.19), were independent risk factors for HCV infection. In conclusion, the major risk factors for HCV infection in Korea are mostly related to conventional or alterative healthcare procedures such as blood transfusion in the remote past, needle stick injury, surgery, dental procedure, and tattooing although multiple sex partners or IVDU plays a minor role.

Purpose: A prognostic index for survival was constructed and validated from patient data from two European Organisation for Research and Treatment of Cancer (EORTC) radiation trials for low-grade glioma (LGG). We sought to independently validate this prognostic index with a separate prospectively collected data set (Intergroup 86-72-51). Methods and Materials: Two hundred three patients were treated in a North Central Cancer Treatment Group-led trial that randomized patients with supratentorial LGG to 50.4 or 64.8 Gy. Risk factors from the EORTC prognostic index were analyzed for prognostic value: histology, tumor size, neurologic deficit, age, and tumor crossing the midline. The high-riskmore » group was defined as patients with more than two risk factors. In addition, the Mini Mental Status Examination (MMSE) score, extent of surgical resection, and 1p19q status were also analyzed for prognostic value. Results: On univariate analysis, the following were statistically significant (p < 0.05) detrimental factors for both progression-free survival (PFS) and overall survival (OS): astrocytoma histology, tumor size, and less than total resection. A Mini Mental Status Examination score of more than 26 was a favorable prognostic factor. Multivariate analysis showed that tumor size and MMSE score were significant predictors of OS whereas tumor size, astrocytoma histology, and MMSE score were significant predictors of PFS. Analyzing by the EORTC risk groups, we found that the low-risk group had significantly better median OS (10.8 years vs. 3.9 years, p < 0.0001) and PFS (6.2 years vs. 1.9 years, p < 0.0001) than the high-risk group. The 1p19q status was available in 66 patients. Co-deletion of 1p19q was a favorable prognostic factor for OS vs. one or no deletion (median OS, 12.6 years vs. 7.2 years; p = 0.03). Conclusions: Although the low-risk group as defined by EORTC criteria had a superior PFS and OS to the high-risk group, this is primarily because of the influence of histology and tumor size. Co-deletion of 1p19q is a prognostic factor. Future studies are needed to develop a more refined prognostic system that combines clinical prognostic features with more robust molecular and genetic data.« less

Background & objectives: Studies conducted to assess the prevalence of cardiovascular (CV) risk factors among different regions of the country show variation in risk factors in different age groups and urban and rural population. We undertook this study to determine the prevalence of cardiovascular risk factors among urban adults in a north Indian city. Methods: In a cross-sectional survey, 2227 subjects aged ≥ 20 yr were studied from April 2008 to June 2009 in Urban Chandigarh, a north Indian city. Demographic history, anthropometry and blood pressure were assessed. Fasting, and 2 h capillary plasma glucose after 75 g glucose load, HDL-C and triglycerides were estimated. Results: The most prevalent cardiovascular risk factors in the age group of 20-29 yr was sedentary lifestyle (63%), while from fourth decade and onwards, it was overweight/obesity (59-85%). The second most common prevalent cardiovascular risk factor in the age group of 20-29 yr was overweight/obesity, in 30-49 yr sedentary lifestyle, in 50-69 yr hypertension and in subjects ≥70 yr, it was hypertriglyceridaemia. The prevalence of overweight/obesity, hypertension, dysglycaemia and smoking was almost double in subjects in the fourth decade of life, as compared to those in the third decade of life. The prevalence of CV risk factors significantly increased with age irrespective of gender and prevalence of low HDL-C was significantly more common in women as compared to men. Interpretation & conclusions: Sedentary lifestyle, obesity and low HDL-C are the most prevalent CV risk factors in subjects in the third and fourth decade of life in this north Indian population and clustering of these cardiovascular risk factors increases with advancing age. Strategies need to be formulated to target this population to prevent the epidemic of cardiovascular disease. PMID:24718400

Little information is available to inform clinical assessments on risk of self-harm repetition in ethnic minority groups. In a prospective cohort study, using data collected from six hospitals in England for self-harm presentations occurring between 2000 and 2007, we investigated risk factors for repeat self-harm in South Asian and Black people in comparison to Whites. During the study period, 751 South Asian, 468 Black and 15,705 White people presented with self-harm in the study centres. Repeat self-harm occurred in 4379 individuals, which included 229 suicides (with eight of these fatalities being in the ethnic minority groups). The risk ratios for repetition in the South Asian and Black groups compared to the White group were 0.6, 95% CI 0.5-0.7 and 0.7, 95% CI 0.5-0.8, respectively. Risk factors for repetition were similar across all three groups, although excess risk versus Whites was seen in Black people presenting with mental health symptoms, and South Asian people reporting alcohol use and not having a partner. Additional modelling of repeat self-harm count data showed that alcohol misuse was especially strongly linked with multiple repetitions in both BME groups. Ethnicity was not recorded in a third of cases which may introduce selection bias. Differences may exist due to cultural diversity within the broad ethnic groups. Known social and psychological features that infer risk were present in South Asian and Black people who repeated self-harm. Clinical assessment in these ethnic groups should ensure recognition and treatment of mental illness and alcohol misuse. Copyright © 2012 Elsevier B.V. All rights reserved.

To develop a human immune deficiency virus (HIV) infection risk appraisal model suitable for men who has sex with men (MSM) in Guangzhou, and to provide tools for follow-up the outcomes on health education and behavior intervention. A cros-sectional study was conducted in Guangzhou from 2008 to 2010. Based on the HIV surveillance data, the main risk factors of HIV infection among MSM were screened by means of logistic regression. Degree on relative risk was transformed into risk scores by adopting the statistics models. Individual risk scores, group risk scores and individual infection risk in comparison with usual MSM groups could then be calculated according to the rate of exposure on those risk factors appeared in data from the surveillance programs. Risk factors related to HIV infection among MSM and the quantitative assessment standard (risk scores and risk scores table of population groups) for those factors were set up by multiple logistic regression, including age, location of registered residence, monthly income, major location for finding their sexual partners, HIV testing in the past year, age when having the first sexual intercourse, rate of condom use in the past six months, symptoms related to sexually transmitted diseases (STDs) and syphilis in particular. The average risk score of population was 6.06, with risk scores for HIV positive and negative as 3.10 and 18.08 respectively (P < 0.001). The rates of HIV infection for different score groups were 0.9%, 2.0%, 7.0%, 14.4% and 33.3%, respectively. The sensitivity and specificity on the prediction of scores were 54.4% and 75.4% respectively, with the accuracy rate as 74.2%. HIV infection risk model could be used to quantify and classify the individual's infectious status and related factors among MSM more directly and effectively, so as to help the individuals to identify their high-risk behaviors as well as lifestyles. We felt that it could also serve as an important tool used for personalized HIV health education and behavior intervention programs.

The paradigm of etiology of early childhood caries (ECC) is shifting toward genetics. Of various inherited factors, blood group of an individual is genetically determined. The aim of the study is to determine if blood group of an individual will serve as a potential risk factor in the development of ECC. A cross-sectional study was conducted in Chennai. Blood samples were collected from a total of 500 children <71 months of age for determination of the blood group. Of which 96 children (24 per blood group) were randomly selected and were included in the study. Oral screening of the selected children was done by a pediatric dentist who was blinded to the blood group of the children. Decayed, extracted, and filling index was noted. Details on other associated factors for the development of ECC such as the socioeconomic status, oral hygiene measures, diet, and feeding practices were collected by directly interviewing the parents through a questionnaire. Statistical analysis was done using Chi-square and Kruskal-Wallis test and post hoc Tukey test with significance level set at 0.05. Intergroup analysis of the associated factors showed no significant differences between the children of different blood groups. A statistically significant relation was noted between the blood groups and development of ECC (P = 0.025). Blood group is a potential risk indicator for the development of ECC.

Accumulated data over the years have suggested that hypoxia inducible factor-1 alpha (HIF-1α) and its downstream vascular endothelial growth factor (VEGF) gene may be linked with chronic obstructive pulmonary disease (COPD). This study aims to investigate the association of HIF-1α and VEGF genetic polymorphisms and their correlated risks with COPD. COPD patients (case group) and healthy individuals (control group) were recruited. DNA was extracted to detect HIF-1α and VEGF genetic polymorphisms. Basal lung volume and forced expiratory capacity in 1st second (FEV1)/forced vital capacity (FVC) and FEV 1 /predicted value (pred)% were calculated. Genotype and allele distributions in HIF-1α and VEGF genes were analyzed. Kaplan-Meier curves and logistic regression model were used for analysis of survival and COPD risk factors. Haplotypes for HIF-1α rs11549465 and rs11549467 were analyzed. FEV 1 /FVC and FEV1/pred% in the case group were lower than the control group. Frequencies of HIF-1α rs11549465 CT + TT genotype and T allele, and rs11549467 GA + AA genotype and A allele were higher in the case group than the control group. Patients with rs11549465 CT + TT had higher COPD risk than those with the CC genotype. Patients with rs11549467 GA + AA showed higher COPD risk and lower FEV 1 /FVC and FEV 1 /pred% than those with the GG genotype. Patients with HIF-1α TA haplotype showed higher COPD risk than those with the CG haplotype. Survival rate of patients with HIF-1α rs11549467 GG genotype was higher than those with the GA + AA genotype. HIF-1α rs11549467 polymorphism may be associated with COPD risk. Copyright © 2017.

Despite the link between the disorder and violent offending, this risk factor has yet to be examined as a predictor of heterogeneity in the development of violent offending among juvenile offenders. It is likely that the impulsivity, genetic link, and generally chronic disorder course which are characteristics of the disorder play roles in predicting violent offending, which is consistent with both self-control theory and general developmental theory related to early life deficits and life-course persistent offending. Past research has also elucidated a developmental trajectory model of violent offending, which is utilized by the present research. The present research examines ADHD as a risk factor predicting trajectory group assignment. The Pathways to Desistance data followed 1,354 juvenile offenders for 84 months following conviction for a serious offense. Using multinomial logistic regression, this study extends past research on the development of violent offending among juvenile offenders by examining ADHD as a risk factor predicting assignment to violent offending trajectory groups. Results indicate that meeting criteria for ADHD at baseline predicted membership to all trajectory groups relative to the Abstaining group when all covariates were included. This increase in risk is highest for the trajectory group characterized by the highest frequency of violent offending. This indicates the relevance of identifying and treating ADHD among juvenile offenders to best mitigate risk of violent recidivism throughout adolescence and early adulthood.

Some medical conditions constitute important risk factors for the development of invasive pneumococcal diseases in children and adolescents aged from 5 to 19 years. Conjugate vaccines have potential efficacy in this scenario, but are not available in many Latin American public healthcare systems for this age group. This study aimed to estimate the preventable fraction of invasive pneumococcal diseases among individuals aged from 5 to 19 years with associated risk factors for its development. Data regarding the Latin America population, risk factors prevalence and conjugate vaccines efficacy were obtained from the literature. Total population at risk ranged from 17.3 to 64.6 million of individuals and asthma was the most impacting risk factor. According to SIREVA, PCV13 provided a 62.9% serotypes coverage in individuals from 5 to 29 years in 2012, potentially increasing the covered population from [8,338,457-31,057,620] with PCV10 to [10,906,356-40,622,078] with PCV13. To date, according to available efficacy data, the hypothetically immunized population ranged from 11.4 to 42.4 million, representing 7.0% to 26.0% of the total population in this age group. Vaccination in risk groups should be encouraged, as it potentially contributes to the reduction in the number of cases of invasive pneumococcal disease. Copyright © 2015 The Authors.

Intimate partner violence (IPV) is a public health problem that reaches across age, sex, and ethnicity. In this study, we examined risk factors for physical IPV perpetration among young adult males and females from four ethnic groups. Data were taken from Waves 1-3 of the National Longitudinal Study of Adolescent Health (Add Health). The sample included 10,141 Wave 3 respondents (ages ranged from 18-27 years old) who reported being in a current romantic relationship. Physical IPV perpetration was reported by 14.10% of White, 23.28% of Black, 18.82% of Latino, and 18.02% of Asian males. Physical IPV perpetration was reported by 19.01% of White, 24.80% of Black, 25.97% of Latina, and 19.21% of Asian females. Following an ecological framework, proximal risk factors at intrapersonal and interpersonal levels were included in the analyses. Despite finding fairly consistent percentage of physical IPV perpetration across sample groups, the risk factors for physical IPV perpetration were rather uncommon across sex and ethnicity. Only 1 factor--psychological IPV perpetration toward a romantic partner--was consistently associated with physical IPV perpetration across all groups. Our findings have implications for tailoring prevention and intervention efforts toward risk factors of physical IPV perpetration that are uniquely associated with biological sex and ethnicity.

To provide scientific evidence, using a literature review on psychosocial risk factors in mental health, that a high exposure to psychosocial stress situations in childhood increases the risk of mental disorders in adulthood,. A literature review up to December 2011 in the electronic databases from Medline, Universitat de Barcelona, and the Universitat Autonoma de Barcelona. The keywords used were: childhood, prenatal, vulnerability, risk, abuse, neglect, child mental disorder, schizophrenia, and prevention. Inclusion criteria for the studies reviewed: 1) designed to investigate childhood risk factors; 2) Comparative studies with persons without risk factors; 3) Studies with sufficient statistical significance; 4) Studies with "n" participants equal to o more than 30 persons. There are a group of easily identifiable mental health risk factors in childhood that can help in the prevention of mental disorders in the adulthood. They can be grouped into four categories: A) Pregnancy, birth and perinatal problems; B) Poor interpersonal relations with parents; C) Adverse life events in the first two years of life; D) Cognitive deficits in primary school, and social isolation during school years. There are life events that may increase the possibilities of suffering some kind of Psychopathology. It is necessary to consider those events as Risk Factors for Mental Health. The accumulation of these Risk Factors increases vulnerability to Mental Disorders. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

Background Clinical manifestations and outcomes of atherosclerotic disease differ between ethnic groups. In addition, the prevalence of risk factors is substantially different. Primary prevention programs are based on data derived from almost exclusively White people. We investigated how race/ethnic differences modify the associations of established risk factors with atherosclerosis and cardiovascular events. Methods We used data from an ongoing individual participant meta-analysis involving 17 population-based cohorts worldwide. We selected 60,211 participants without cardiovascular disease at baseline with available data on ethnicity (White, Black, Asian or Hispanic). We generated a multivariable linear regression model containing risk factors and ethnicity predicting mean common carotid intima-media thickness (CIMT) and a multivariable Cox regression model predicting myocardial infarction or stroke. For each risk factor we assessed how the association with the preclinical and clinical measures of cardiovascular atherosclerotic disease was affected by ethnicity. Results Ethnicity appeared to significantly modify the associations between risk factors and CIMT and cardiovascular events. The association between age and CIMT was weaker in Blacks and Hispanics. Systolic blood pressure associated more strongly with CIMT in Asians. HDL cholesterol and smoking associated less with CIMT in Blacks. Furthermore, the association of age and total cholesterol levels with the occurrence of cardiovascular events differed between Blacks and Whites. Conclusion The magnitude of associations between risk factors and the presence of atherosclerotic disease differs between race/ethnic groups. These subtle, yet significant differences provide insight in the etiology of cardiovascular disease among race/ethnic groups. These insights aid the race/ethnic-specific implementation of primary prevention. PMID:26134404

Pleural infections are associated with significant morbidity and mortality. The recently developed RAPID (renal, age, purulence, infection source, and dietary factors) score consists of five clinical factors that can identify patients at risk for increased mortality. The objective of this study was to further validate the RAPID score in a diverse cohort, identify factors associated with mortality, and provide long-term outcomes. We evaluated a single-center retrospective cohort of 187 patients with culture-positive pleural infections. Patients were classified by RAPID scores into low-risk (0-2), medium-risk (3-4), and high-risk (5-7) groups. The Social Security Death Index was used to determine date of death. All-cause mortality was assessed at 3 months, 1 year, 3 years, and 5 years. Clinical factors and comorbid conditions were evaluated for association. Three-month mortality for low-, medium-, and high-risk groups was 1.5, 17.8, and 47.8%, respectively. Increased odds were observed among medium-risk (odds ratio, 14.3; 95% confidence interval, 1.8-112.6; P = 0.01) and high-risk groups (odds ratio, 53.3; 95% confidence interval, 6.8-416.8; P < 0.01). This trend continued at 1, 3, and 5 years. Factors associated with high-risk scores include gram-negative rod infections, heart disease, diabetes, cancer, lung disease, and increased length of stay. When applied to a diverse patient cohort, the RAPID score predicts outcomes in patients up to 5 years and may aid in long-term risk stratification on presentation.

whole-body vibration training may improve neuromuscular function, falls risk and bone density, but previous studies have had conflicting findings. this study aimed to evaluate the influence of vertical vibration (VV) and side-alternating vibration (SV) on musculoskeletal health in older people at risk of falls. single-blind, randomised, controlled trial comparing vibration training to sham vibration (Sham) in addition to usual care. participants were 61 older people (37 women and 24 men), aged 80.2 + 6.5 years, referred to an outpatient falls prevention service. participants were randomly assigned to VV, SV or Sham in addition to the usual falls prevention programme. Participants were requested to attend three vibration sessions per week for 12 weeks, with sessions increasing to six, 1 min bouts of vibration. Falls risk factors and neuromuscular tests were assessed, and blood samples collected for determination of bone turnover, at baseline and following the intervention. chair stand time, timed-up-and-go time, fear of falling, NEADL index and postural sway with eyes open improved in the Sham group. There were significantly greater gains in leg power in the VV than in the Sham group and in bone formation in SV and VV compared with the Sham group. Conversely, body sway improved less in the VV than in the Sham group. Changes in falls risk factors did not differ between the groups. whole-body vibration increased leg power and bone formation, but it did not provide any additional benefits to balance or fall risk factors beyond a falls prevention programme in older people at risk of falls. © The Author 2014.

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 < 0.001), number of patients without 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 < 0.001). Using the model of multi-variant logistic regression, insight, deficit of psycho-education and social isolation (p < 0.05) were identified as predictors of depression and suicidal risk in schizophrenia. This study shows that considered 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.

Explore psychological functioning in adolescents with a cleft at age 16 from a broad perspective, including cognitive, emotional, behavioral, appearance-related, and psychosocial adjustment. High-risk groups were identified within each area of adjustment to investigate whether vulnerable adolescents were found across domains or whether risk was limited to specific areas of adjustment. Cross-sectional data based on psychological assessments at age 16 (N = 857). The effect of gender, cleft visibility, and the presence of an additional condition were investigated on all outcome variables. Results were compared with large national samples. Hopkins Symptom Checklist, Harter Self-Perception Scale for Adolescents, Child Experience Questionnaire, and Satisfaction With Appearance scale. The main factor influencing psychological adjustment across domains was gender, with girls in general reporting more psychological problems, as seen in reference groups. The presence of an additional condition also negatively affected some of the measures. No support was found for cleft visibility as a risk factor except for dissatisfaction with appearance. Correlation analyses of risk groups seem to point to an association between social and emotional risk and between social risk and dissatisfaction with appearance. Associations between other domains were found to be weak. The results point to areas of both risk and strength in adolescents born with a cleft lip and/or palate. Future research should investigate how protective factors could counteract potential risk in adolescents with a cleft.

A limited number of studies have described the epidemiology of open fractures, and the epidemiology of open ankle fractures is not an exception. Therefore, the risk factors associated with open ankle fractures have not been extensively evaluated. The frequencies and proportions of open ankle fractures among all the recorded malleolar fractures in the US National Trauma Data Bank data set from January 2007 to December 2011 were analyzed. Clinically relevant variables captured in the data set were also used to evaluate the risk factors associated with open ankle fractures, adjusting for other covariates. The entire cohort was further subdivided into "lower" and "higher" energy trauma groups and the same analysis performed for each group separately. We found that a body mass index of >40 kg/m(2) and farm location were risk factors for open ankle fractures and impaired sensorium was protective against open ankle fractures. In the "lower energy" group, male gender, alcohol use, peripheral vascular disease, other injuries, and injury occurring at a farm location were risk factors for open fractures. In the "higher energy" group, female gender, work-related injury, and injury at a farm or industry location demonstrated statistically significantly associations with open fractures.

The aim of our study was to estimate whether the placement of cerclage in pregnancy to prevent preterm birth (PTB) is associated with higher incidence of intrapartum cervical lacerations. A retrospective cohort study was conducted on singleton pregnancies with risk factors for PTB. The study group consisted of women with either a history- or ultrasound-indicated cerclage placed between 12 and 24 weeks of gestation, while the control group consisted of women with similar risk factors for PTB but who did not receive a cerclage. Primary outcome was the incidence of intrapartum cervical lacerations. A sample size calculation was performed on the basis of the results of previous studies on cervical lacerations. We identified 134 women who had a cerclage placed in pregnancy. They were compared with 236 controls with no cerclage. Cases and controls had similar risk factors for cervical lacerations. Cervical lacerations occurred with similar frequencies in the cerclage and no-cerclage group (2.2 vs 1.3%, p = 0.78). There was no significant difference between the two groups for the risk of cervical lacerations (RR 1.76, 95% CI: 0.36-8.60). Cerclage placement during pregnancy is not associated with an increased risk of intrapartum cervical lacerations.

This study evaluated the effectiveness of augmenting a youth suicide-preventive intervention with a brief, home-based parent program. A total of 615 high school youth and their parents participated. Three suicide prevention protocols, a youth intervention, a parent intervention, and a combination of youth and parent intervention, were compared with an "intervention as usual" (IAU) group. All groups experienced a decline in risk factors and an increase in protective factors during the intervention period, and sustained these improvements over 15 months. Results reveal that the youth intervention and combined youth and parent intervention produced significantly greater reductions in suicide risk factors and increases in protective factors than IAU comparison group.

This study compared the efficacy of a media literacy program and a self-esteem program designed to reduce general and specific risk factors for eating disorders. Four classes of 86 grade 8 students (53 boys and 33 girls), mean age of 13 years, were randomly assigned to either a control condition or one of the two intervention conditions. Assessment of general and specific risk factors was carried out at baseline, postintervention and 3-month follow-up. At postintervention the media literacy group had lower mean scores on weight concern than the control group (p =0.007) but the self-esteem group did not. There were some differences on self-esteem measures at the 3-month follow-up. Media literacy programs combined with an interactive, student-centered framework may potentially be a safe and effective way of reducing risk factors for eating disorders. The impact of teaching style needs to be further evaluated in prevention research. Copyright 2003 by Wiley Periodicals, Inc.

Hypertension, one of the modifiable risk factors for cardiovascular disease (CVD), is known to be associated with increased oxidative stress and reduced cardiovagal modulation. Similar to hypertension, prehypertension is associated with increased risk of adverse cardiovascular (CV) events. We planned this study to find the association between prehypertension, cardiovagal modulation, oxidative stress, and associated CV risk factors. We recruited 178 subjects through hypertension screening camps conducted in Puducherry, India. Subjects were grouped into prehypertensive (n = 97) and normotensive (n = 81) groups. They were further subdivided, based on age, as young (20-39 years) and middle-aged (40-60 years) adults. We measured basal physiological parameters, heart rate variability, oxidative stress (thiobarbituric acid reactive substance and total antioxidant capacity (TAC)), and CV risk factors. We found significant increase in oxidative stress in prehypertensive subjects of both age groups but the cardiovagal modulation decreased significantly in young prehypertensive subjects when compared with normotensive subjects. Correlation of TAC with root mean square of the sum of successive R wave to R wave (RR) interval differences (RMSSD), a cardiovagal modulation parameter (r = 0. 437; P < 0.001), and mean arterial pressure (MAP) (r = -0.318; P < 0.001) was significant even after adjusting for CV risk factors. The correlation between MAP and RMSSD (r = 0.199; P = 0.009) was reduced after adjusting for CV risk factors. Prehypertension in young adults is associated with increased oxidative stress and altered cardiovagal modulation. The risk factors for CVDs in prehypertensive young adults were found to be equivalent to that of middle-aged adults who are in the twilight zone for developing CV dysfunctions.

Objectives The incidence of sensorineural hearing loss is between 1 and 3 per 1000 in healthy neonates and 2–4 per 100 in high-risk infants. The national universal neonatal hearing screening carried out in Poland since 2002 enables selection of infants with suspicion and/or risk factors of hearing loss. In this study, we assessed the incidence and risk factors of hearing impairment in infants ≤33 weeks’ gestational age (wga). Methods We analyzed the database of the Polish Universal Newborns Hearing Screening Program from 2010 to 2013. The study group involved 11438 infants born before 33 wga, the control group—1487730 infants. Screening was performed by means of transient evoked otoacoustic emissions. The risk factors of hearing loss were recorded. Infants who failed the screening test and/or had risk factors were referred for further audiological evaluation. Results Hearing deficit was diagnosed in 11% of infants ≤25 wga, 5% at 26–27 wga, 3.46% at 28 wga and 2–3% at 29–32 wga. In the control group the incidence of hearing deficit was 0.2% (2.87% with risk factors). The most important risk factors were craniofacial malformations, very low birth weight, low Apgar score and mechanical ventilation. Hearing screening was positive in 22.42% newborns ≤28 wga and 10% at 29–32 wga and in the control group. Conclusions Hearing impairment is a severe consequence of prematurity. Its prevalence is inversely related to the maturity of the baby. Premature infants have many concomitant risk factors which influence the occurrence of hearing deficit. PMID:28910311

Wage Differentials between Heat-Exposure Risk and No Heat-Exposure Risk Groups

The goal of this study is to investigate the wage differential between groups of workers who are exposed to heat and those who are not. Workers in the heat-exposure risk group are defined as workers who work in conditions that cause them to spend more than 25% of their work hours at high temperatures. To analyze the wage differential, the Blinder-Oaxaca and Juhn-Murphy-Pierce methods were applied to Korea Working Condition Survey data. The results show that the no heat-exposure risk group received higher wages. In most cases, this can be interpreted as the endowment effect of human capital. As a price effect that lowers the endowment effect, the compensating differential for the heat-exposure risk group was found to be 1%. Moreover, education level, work experience, and employment status counteracted the compensating differentials for heat-exposure risks. A comparison of data sets from 2011 and 2014 shows that the increasing wage gap between the two groups was not caused by systematic social discrimination factors. This study suggests that wage differential factors can be modified for thermal environmental risks that will change working conditions as the impact of climate change increases. PMID:28672804

Cardiovascular diseases (CVDs) are the main cause of death and disability in Poland. There are many risk factors of CVD which are modifiable due to preventive strategies. Knowledge about these factors among population at risk of CVD is the most important condition for success of them. To evaluate the knowledge of CVD risk factors among soldiers of the Polish Army and try to identify a demographic factors influenced on them. Authors investigated the level of knowledge about CVD risk factors among 644 soldiers (aged between 18 to 62 years) using the special questionnaire. Whole group was analyzed according to a place of origin: city, town and village and according to a function: professionals and conscripts. Soldiers achieved a total score of 58.4% correct answers. Commonly known risk factors of CVD (average 82% of correct answers) in studied group were: obesity, tobacco smoking, high level of cholesterol and hypertension. Knowledge about above risk factors was significantly higher (p < 0.01) than about other. Lesser known risk factors (average 54% of correct answers) were: male gender, abnormal diet, sedentary lifestyle, family history of CVDs, diabetes, family history of heart infarction below 55 yrs and peripheral atherosclerosis. residents achieved 64.5% correct answers, town--61.5%, and village--58%. Professionals achieved 65.1% vs. 58.8% for conscripts. The level of knowledge about CVD risk factors are significantly higher among professionals than in urban population. Our data confirm the need of continuation and developing new CVDs preventive strategies in Poland, especially among poor educated and village populations. There is a need to emphasize the role of lesser known, modifiable CVD risk factors (e.g., obesity, sedentary lifestyle) in existing and future health programs.

Socio-economic position (SEP) and ethnicity influence type 2 diabetes mellitus (T2DM) risk in adults. However, the influence of SEP on emerging T2DM risks in different ethnic groups and the contribution of SEP to ethnic differences in T2DM risk in young people have been little studied. We examined the relationships between SEP and T2DM risk factors in UK children of South Asian, black African-Caribbean and white European origin, using the official UK National Statistics Socio-economic Classification (NS-SEC) and assessed the extent to which NS-SEC explained ethnic differences in T2DM risk factors. Cross-sectional school-based study of 4,804 UK children aged 9-10 years, including anthropometry and fasting blood analytes (response rates 70%, 68% and 58% for schools, individuals and blood measurements). Assessment of SEP was based on parental occupation defined using NS-SEC and ethnicity on parental self-report. Associations between NS-SEC and adiposity, insulin resistance (IR) and triglyceride differed between ethnic groups. In white Europeans, lower NS-SEC status was related to higher ponderal index (PI), fat mass index, IR and triglyceride (increases per NS-SEC decrement [95%CI] were 1.71% [0.75, 2.68], 4.32% [1.24, 7.48], 5.69% [2.01, 9.51] and 3.17% [0.96, 5.42], respectively). In black African-Caribbeans, lower NS-SEC was associated with lower PI (-1.12%; [-2.01, -0.21]), IR and triglyceride, while in South Asians there were no consistent associations between NS-SEC and T2DM risk factors. Adjustment for NS-SEC did not appear to explain ethnic differences in T2DM risk factors, which were particularly marked in high NS-SEC groups. SEP is associated with T2DM risk factors in children but patterns of association differ by ethnic groups. Consequently, ethnic differences (which tend to be largest in affluent socio-economic groups) are not explained by NS-SEC. This suggests that strategies aimed at reducing social inequalities in T2DM risk are unlikely to reduce emerging ethnic differences in T2DM risk.

The effect of aquatic exercise and education on lowering fall risk in older adults with hip osteoarthritis.

PubMed

Arnold, Cathy M; Faulkner, Robert A

2010-07-01

To evaluate the effect of aquatic exercise and education on fall risk factors in older adults with hip osteoarthritis (OA). Seventy-nine adults, 65 years of age or older with hip OA and at least 1 fall risk factor, were randomly assigned to 1 of 3 groups: aquatics and education (AE; aquatic exercise twice a wk with once-a-wk group education), aquatics only (A; 2 wk aquatic exercise) and control (C; usual activity). Balance, falls efficacy, dual-task function, functional performance (chair stands), and walking performance were measured pre- and postintervention or control period. There was a significant improvement in fall risk factors (full-factorial MANCOVA, baseline values as covariates; p = .038); AE improved in falls efficacy compared with C and in functional performance compared with A and C. The combination of aquatic exercise and education was effective in improving fall risk factors in older adults with arthritis.

Friendship Group Composition and Juvenile Institutional Misconduct.

PubMed

Reid, Shannon E

2017-02-01

The present study examines both the patterns of friendship networks and how these network characteristics relate to the risk factors of institutional misconduct for incarcerated youth. Using friendship networks collected from males incarcerated with California's Division of Juvenile Justice (DJJ), latent profile analysis was utilized to create homogeneous groups of friendship patterns based on alter attributes and network structure. The incarcerated youth provided 144 egocentric networks reporting 558 social network relationships. Latent profile analysis identified three network profiles: expected group (67%), new breed group (20%), and model citizen group (13%). The three network profiles were integrated into a multiple group analysis framework to examine the relative influence of individual-level risk factors on their rate of institutional misconduct. The analysis finds variation in predictors of institutional misconduct across profile types. These findings suggest that the close friendships of incarcerated youth are patterned across the individual characteristics of the youth's friends and that the friendship network can act as a moderator for individual risk factors for institutional misconduct.

We assessed the prevalence and risk factors of malnutrition in elderly cancer patients. We studied a prospective cohort of solid cancer patients aged ≥70 years at referral to two geriatric oncology clinics between 2007 and 2010. Nutrition was evaluated using the Mini-Nutritional Assessment (MNA) using validated cut-offs (<17: malnutrition, 17-23.5: at-risk for malnutrition). Patients with non-digestive tumours (breast, prostate, urinary tract) and with digestive (colorectal, upper digestive tract and liver) were analysed separately using multinomial logistic regression. Of 643 consecutive patients, 519 had available data (median age, 80; men, 48.2%; metastases, 46.3%; digestive cancer 47.8%). In non-digestive group, 13.3% had malnutrition versus 28.6% in digestive group. The link between metastasis and malnutrition was significantly higher in non-digestive group (adjusted odds ratio [ORa ], 25.25; 95%CI: 5.97-106.8) than in digestive group (ORa, 2.59; 1.08-6.24; p for heterogeneity = 0.04). Other factors independently associated with malnutrition were cognitive impairment (ORa MMMSE ≤ 24 versus > 24 in non-digestive group: 16.68; 4.89-56.90 and in digestive group: 3.93; 1.34-11.50), and depressed mood (ORa MiniGDS ≥1 versus <1 in non-digestive group: 11.11; 3.32-37.17 and in digestive group: 3.25; 1.29-8.15) and fall risk (ORa fall risk versus no fall risk in non-digestive group: 4.68; 1.77-12.37; in digestive group: 100% of malnourished patients were faller's). We highlighted, in elderly cancer patients, the high prevalence of malnutrition and that geriatrics syndromes (i.e. cognitive impairment, depressed mood and fall risk) were independent risk factors for malnutrition. Moreover, metastatic status was significantly much more strongly associated with malnutrition in non-digestive than digestive tumours.

Risk factors and cognitive sequelae of brain arteriolosclerosis pathology are not fully understood. To address this, we used multimodal data from the National Alzheimer's Coordinating Center and Alzheimer's Disease Neuroimaging Initiative data sets. Previous studies showed evidence of distinct neurodegenerative disease outcomes and clinical-pathological correlations in the “oldest-old” compared to younger cohorts. Therefore, using the National Alzheimer's Coordinating Center data set, we analyzed clinical and neuropathological data from two groups according to ages at death: < 80 years (n = 1008) and ≥80 years (n = 1382). In both age groups, severe brain arteriolosclerosis was associated with worse performances on global cognition tests. Hypertension (but not diabetes) was a brain arteriolosclerosis risk factor in the younger group. In the ≥ 80 years age at death group, an ABCC9 gene variant (rs704180), previously associated with aging-related hippocampal sclerosis, was also associated with brain arteriolosclerosis. A post-hoc arterial spin labeling neuroimaging experiment indicated that ABCC9 genotype is associated with cerebral blood flow impairment; in a convenience sample from Alzheimer's Disease Neuroimaging Initiative (n = 15, homozygous individuals), non-risk genotype carriers showed higher global cerebral blood flow compared to risk genotype carriers. We conclude that brain arteriolosclerosis is associated with altered cognitive status and a novel vascular genetic risk factor. PMID:26738751

Suicide remains a significant public health problem worldwide. This study is aimed at analyzing and presenting contemporary methods in suicide prevention in the world as well as at identifying specific risk groups and risk factors in order to explain their importance. in suicide prevention. The literature search covered electronic databases PubMed, Web of Science and Scopus. In order to select the relevant articles, the authors searched for the combination of key-words which included the following medical subject heading terms (suicide or suicide ideation or attempted) and (prevention or risk factors) and (man or elders or mental disorders). Data analysis covered meta-analyses, systematic reviews and original scientific papers with different characteristics of suicide preventions, risk factors and risk groups. Worldwide evidence-based interventions for suicide prevention are divided in universal, selective and indicated interventions. Restricted approach to various methods of committing suicide as well as pharmacotherapy contributes to a lower suicide rate. Suicide risk factors can be categorized as proximal and distal. The following groups are at highest risk of committing suicide: males. older persons and persons with registered psychiatric disorders. There is a lot of evidence that suicide is preventable. It is known that only 28 coun tries in the world have national suicide prevention strategies and Serbia is not one of them.

Male pattern baldness is not associated with established cardiovascular risk factors in the general population.

A number of studies have shown an association between male pattern baldness (MPB) and cardiovascular disease. Few of these studies, however, have examined whether MPB is a novel risk factor, or is associated with abnormalities of established coronary risk factors. We have therefore performed an analysis of MPB and cardiovascular risk factors in the general population. A total of 1219 male participants aged 18-70 years from the Victorian Family Heart Study were surveyed using a validated questionnaire for degree and pattern of baldness. Carefully standardized measures of height, weight, blood pressure, pulse rate, total and high-density lipoprotein cholesterol, and plasma fibrinogen were made. Subjects were grouped according to the degree and pattern of baldness as: no baldness, frontal baldness and vertex baldness. Bald men were older than non-bald men (P < 0.0001). Age was also associated with increased levels of coronary risk factors (P < 0.0001). When multiple regression was used to adjust for age differences, the levels of coronary risk factors were not significantly different between the bald and non-bald groups. The lack of association between baldness and established coronary risk factors implies that baldness may predispose to coronary heart disease through novel mechanisms yet to be defined.

Diabetes is increasing worldwide, and information on risk factors to develop targeted interventions is limited. Therefore, we analyzed data of the Suriname Health Study to estimate the prevalence of prediabetes and diabetes. We also explored whether ethnic differences in prediabetes or diabetes risk could be explained by biological, demographic, lifestyle, anthropometric, and metabolic risk factors. The study was designed according to the WHO Steps guidelines. Fasting blood glucose levels were measured in 3393 respondents, aged 15-65 years, from an Amerindian, Creole, Hindustani, Javanese, Maroon or Mixed ethnic background. Prediabetes was defined by fasting blood glucose levels between 6.1 and 7.0 mmol/L and diabetes by fasting blood glucose levels ≥7.0 mmol/L or 'self-reported diabetes medication use.' For all ethnicities, we analyzed sex, age, marital status, educational level, income status, employment, smoking status, residence, physical activity, body mass index, waist circumference, hypertension, and the levels of triglyceride, total cholesterol, high-density lipoprotein-cholesterol and low-density lipoprotein-cholesterol. The prevalence of prediabetes was 7.4%, while that of diabetes was 13 0%. From these diabetes cases, 39.6% were not diagnosed previously. No ethnic differences were observed in the prevalence of prediabetes. For diabetes, Hindustanis (23.3%) had twice the prevalence compared to other ethnic groups (4.7-14.2%). The associations of the risk factors with prediabetes or diabetes varied among the ethnic groups. The differences in the associations of ethnic groups with prediabetes or diabetes were partly explained by these risk factors. The prevalence of diabetes in Suriname is high and most elevated in Hindustanis. The observed variations in risk factors among ethnic groups might explain the ethnic differences between these groups, but follow-up studies are needed to explore this in more depth.

Prior to 1994, plantar fascia ruptures were considered as an acute injury that occurred primarily in athletes. However, plantar fascia ruptures have recently been reported in the setting of preexisting plantar fasciitis. We analyzed risk factors causing plantar fascia rupture in the presence of preexisting plantar fasciitis. We retrospectively reviewed 286 patients with plantar fasciitis who were referred from private clinics between March 2004 and February 2008. Patients were divided into those with or without a plantar fascia rupture. There were 35 patients in the rupture group and 251 in the nonrupture group. The clinical characteristics and risk factors for plantar fascia rupture were compared between the 2 groups. We compared age, gender, the affected site, visual analog scale pain score, previous treatment regimen, body mass index, degree of ankle dorsiflexion, the use of steroid injections, the extent of activity, calcaneal pitch angle, the presence of a calcaneal spur, and heel alignment between the 2 groups. Of the assessed risk factors, only steroid injection was associated with the occurrence of a plantar fascia rupture. Among the 35 patients with a rupture, 33 had received steroid injections. The odds ratio of steroid injection was 33. Steroid injections for plantar fasciitis should be cautiously administered because of the higher risk for plantar fascia rupture.

Objectives: Insomnia and sleep apnea frequently co-occur and are independently associated with an increased risk of cardiovascular disease, but little is known about cardiovascular disease risk among individuals with comorbid insomnia and sleep apnea. The current study examined traditional risk factors and a physiologic biomarker of cardiovascular risk in comorbid insomnia and sleep apnea. Design: Community-based participatory research study. Participants: The sample comprised 795 participants without preexisting cardiovascular disease from the Heart Strategies Concentrating On Risk Evaluation (Heart SCORE) study. Measurements and Results: Participants were assessed for symptoms of insomnia and sleep apnea risk, as well as for presence of obesity, smoking, a sedentary lifestyle, hypertension, dyslipidemia, and diabetes. Baseline resting brachial artery diameter was measured by B-mode ultrasonography. A total of 138 participants (17.4%) met criteria for insomnia syndrome alone, 179 (22.5%) were at high risk for sleep apnea alone, 95 (11.9%) reported both insomnia syndrome and high sleep apnea risk, and 383 (48.2%) reported having neither insomnia nor sleep apnea symptoms Both high sleep apnea risk alone and comorbid insomnia and high sleep apnea risk groups had greater frequencies of obesity, sedentary lifestyle, hypertension, and three or more traditional cardiovascular risk factors and significantly larger brachial artery diameters than the insomnia alone group and those without insomnia or sleep apnea symptoms. No differences in traditional cardiovascular risk factors or brachial artery diameter were found between the high sleep apnea risk and comorbid groups. Conclusions: These findings suggest that sleep apnea is a major contributor to cardiovascular risk and co-occurring insomnia does not appear to add to this risk.

Since a history of stroke or transient ischaemic attack is a major risk factor for a recurrent event, lifestyle counselling during the hospital phase is an essential component of treatment and may increase the probability of lifestyle change. To study the effect of risk factor-targeted lifestyle counselling intervention on working-age stroke patients' adherence to lifestyle changes. A quasi-experimental, nonequivalent control group pretest-post-test design. Stroke patients in an acute neurological unit were divided into a control group (n = 75) receiving standard counselling and an experimental group (n = 75) receiving risk factor-targeted counselling. Lifestyle data and clinical outcomes were collected at hospital between January 2010 and October 2011, while data on adherence to lifestyle changes 3, 6, and 12 months after discharge. The baseline lifestyle habits did not differ significantly other than in alcohol behaviour. Both groups increased their intake, but the intervention group to a lesser degree. However, the experimental group significantly lost their weight for the first 3 and 6 months; at 3 months reduction in cigarette consumption and at 6 months significant increases in smoking cessation were also achieved. All improved some of their lifestyle habits. Intervention was associated with support from nurses as well as from family and friends. Adherence scores were higher in the experimental group. Some short-term advantages in lifestyle habits due to the intervention were noted. Participants in both groups improved some of their lifestyle habits. © 2016 Nordic College of Caring Science.

Diagnosis and preventive treatment of latent tuberculosis infection (LTBI) among high-risk groups is recommended to achieve tuberculosis (TB) elimination in low-incidence countries.We studied TB incidence rates among those notified with LTBI in the Netherlands from 2005 to 2013 and analysed associated risk factors. We stratified analyses by target group for screening, and by initiation and completion of preventive treatment.The incidence for those completing, stopping and not receiving preventive treatment was 187, 436 and 355 per 100 000 person-years for contacts of TB patients, respectively, and 63, 96 and 110 per 100 000 person-years for other target groups. The rate ratio for TB development among contacts compared to other target groups was 3.1 (95% CI 2.0-4.9). In both groups, incidence was highest in the first year after diagnosis. Independent factors associated with progression to TB among contacts were age <5 years and stopping preventive treatment within 28 days compared to those not receiving preventive treatment. Among other target groups, being foreign born was the only risk factor associated with the risk of developing TB.We conclude that the epidemiological impact of preventive treatment is highest in contacts of TB patients and limited in other target groups for LTBI management in the Netherlands.

Several studies have reported a high risk of local disease recurrence (LR) and locoregional disease recurrence (LRR) in patients with breast cancer after neoadjuvant chemotherapy (NCT) and breast-conserving therapy (BCT). The objective of the current study was to identify potential risk factors for LR and LRR after NCT and BCT. Individual patient data sets from 9 studies were pooled. The outcomes of interest were the occurrence of LR and/or LRR. A 1-stage meta-analytic approach was used. Cox proportional hazards regression models were applied to identify factors that were predictive of LR and LRR, respectively. A total of 9 studies (4125 patients) provided their data sets. The 10-year LR rate was 6.5%, whereas the 10-year LRR rate was 10.3%. Four factors were found to be associated with a higher risk of LR: 1) estrogen receptor-negative disease; 2) cN + disease; 3) a lack of pathologic complete response in axilla (pN0); and 4) pN2 to pN3 disease. The predictive score for LR determined 3 risk groups: a low-risk, intermediate-risk, and high-risk group with 10-year LR rates of 4.0%, 7.9%, and 20.4%, respectively. Two additional factors were found to be associated with an increased risk of LRR: cT3 to cT4 disease and a lack of pathologic complete response in the breast. The predictive score for LRR determined 3 risk groups; a low-risk, intermediate-risk, and high-risk group with 10-year LRR rates of 3.2%, 10.1%, and 24.1%, respectively. BCT after NCT appears to be an oncologically safe procedure for a large percentage of patients with breast cancer. Two easy-to-use clinical scores were developed that can help clinicians to identify patients at higher risk of LR and LRR after NCT and BCT and individualize the postoperative treatment plan and follow-up.

Retinoblastoma can extend beyond the structures of the eye, where cells can enter the bloodstream and cause metastases. Various types of protocols for adjuvant treatment risk-adapted according to histopathological risk factors are used worldwide. Between 1997 and 2009, 420 children were diagnosed with retinoblastoma at the German Retinoblastoma Referral Centre and risk factors were assessed. Patients with post-laminar optic nerve infiltration or choroid or minor scleral invasion received six courses of adjuvant chemotherapy using vincristine, etoposide, carboplatin and cyclophosphamide (group 1). Patients with microscopic extension beyond the sclera to the resection margin of the optic nerve or potential spread due to vitrectomy received chemotherapy plus orbital radiotherapy (group 2). Neoadjuvant chemotherapy was performed in patients with local extraocular invasion detected on MRI. Following this protocol, 42 of the 420 patients and 21 referred from other centres showed high-risk histopathological factors qualifying for adjuvant therapy (57 in group 1 and 6 in group 2). Seven of the 63 patients received neoadjuvant and adjuvant treatment. During a mean follow-up of 5.8 (range 0.4-15.4) years, one of six patients in group 2 developed metastases and died. No patients died from toxicity. The 5-year overall survival was 100% for group 1 and 80% for group 2. This retrospective single-site study reveals a 10% incidence of high-risk features in children with retinoblastoma diagnosed at the German Retinoblastoma Referral Centre. Overall survival rates of 98.3% underline the safety of this adjuvant chemotherapy protocol and its efficiency in preventing metastasis. Published by the BMJ Publishing Group Limited.

Stanford, Sarah; Jones, Michael P; Hudson, Jennifer L

2018-05-01

Past research identifies a number of risk factors for adolescent self-harm, but often fails to account for overlap between these factors. This study investigated the underlying, broader concepts by identifying different psychological profiles among adolescents. We then compared new self-harm rates over a six-month period across different psychological profiles. Australian high school students (n = 326, 68.1% female) completed a questionnaire including a broad range of psychological and socioenvironmental risk and protective factors. Non-hierarchical cluster analysis produced six groups with different psychological profiles at baseline and rate of new self-harm at follow-up. The lowest rate was 1.4% in a group that appeared psychologically healthy; the highest rate was 37.5% in a group that displayed numerous psychological difficulties. Four groups with average self-harm had varied psychological profiles including low impulsivity, anxiety, impulsivity, and poor use of positive coping strategies. Identifying multiple profiles with distinct psychological characteristics can improve detection, guide prevention, and tailor treatment.

Relationships between coronary heart disease risk factors and serum ionized calcium in Kennedy Space Center Cohort

Kennedy Space Center (KSC) employees are reported to be at high risk for coronary heart disease (CHD). Risk factors for CHD include high serum total cholesterol levels, low levels of high-density lipoprotein cholesterol (HDLC), elevated triglyceride, smoking, inactivity, high blood pressure, being male, and being older. Higher dietary and/or serum calcium Ca(++) may be related to a lower risk for CHD. Fifty men and 37 women participated. Subjects were tested in the morning after fasting 12 hours. Information relative to smoking and exercise habits was obtained; seated blood pressures were measured; and blood drawn. KCS men had higher risk values than KCS women as related to HDLC, triglycerides, systolic blood pressure, and diastolic blood pressure. Smoking and nonsmoking groups did not differ for other risk factors or for serum Ca(++) levels. Exercise and sedentary groups differed in total cholesterol and triglyceride levels. Serum Ca(++) levels were related to age, increasing with age in the sedentary group and decreasing in the exercisers, equally for men and women. It is concluded that these relationships may be significant to the risk of CHD and/or the risk of bone demineralization in an aging population.

Post-menopausal osteoporosis is seen in all racial groups. With the increasing population and longevity of minority groups, osteoporosis is becoming an important health concern. Data regarding risk factors for, and prevalence of, low bone mass and awareness of osteoporosis risk in African American (AA) women are limited. This article evaluates the risk factors for, and prevalence of, low bone mass in a population of urban AA women in Wisconsin and assesses this group's perceived risk for osteoporosis. One hundred fifty consecutive community-dwelling AA women > or = 45 years old from Milwaukee, Wis were asked to complete a questionnaire based on currently accepted osteoporosis risk factors. Additionally, their perception of osteoporosis risk was assessed using a Likert scale. All subjects underwent quantitative calcaneal ultrasound. Subject mean age was 54 +/- 7 years. Mean T- and Z-scores were 0.5 and 0.4, respectively. Applying World Health Organization criteria, osteopenia (bone mineral density T-score <-1.0) was present in 23.3% and osteoporosis (bone mineral density <-2.5) in 9.3%. Multivariate analysis of risk factors showed that lifetime incidence of at least 1 fracture, multiparity (>2 children), postmenopausal state, and current smoking were associated with lower calcaneal bone mass. Higher education and presence of diabetes were associated with a higher bone mass. Only 25% of the women surveyed thought they were at moderate to high risk for osteoporosis. Low bone mass was present in 33% of these AA women despite their relative young age. Many AA women do not perceive osteoporosis as a health risk. It is necessary to develop strategies to educate AA women regarding osteoporosis risk.

Background Owing to inconsistent epidemiologic evidence and the presence of confounding factors, the relation between occupational noise exposure and hypertension still remained unclear. We aimed to assess whether Chinese coal miners were at risk of developing hypertension and noise induced hearing loss (NIHL), and whether occupational noise exposure was a risk factor of hypertension. Methods A questionnaire was designed to collect information from 738 study participants, all of whom were employees from the Datun Xuzhou Coal Company. The participants were divided into a noise-exposed group and a control group based on the noise level to which they were exposed in the workplace. The differences in the mean of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were compared between the noise-exposed and control groups. Also the prevalence and age-adjusted odds ratio (OR) [95% confidence intervals (CIs)] of audiometric deficit and hypertension was compared in the study. Binary logistic regression was used to assess the relation between occupational noise level and hypertension while controlling for potential confounding factors. Results Hypertension was more prevalent in noise-exposed group than the control group, 29.2% vs. 21.2% (P=0.012). The noise-exposed group faced an increased risk of hypertension (age-adjusted OR =1.52, 95% CI =1.07–2.15) when the control group was used as reference. The mean values of SBP and DBP of the noise-exposed groups were significantly higher than the control group (P=0.006 and P=0.002 respectively). Hearing loss at low frequencies was significantly more prevalent in the noise-exposed group than the control group, 12.8% vs. 7.4% (P=0.015), while the noise-exposed group faced the increased risk of hearing loss at low frequencies (age-adjusted OR =1.81, 95% CI =1.10–2.96). LEX, 8h (OR =1.036, 95% CI =1.012–1.060) was an independent risk of hypertension when controlling for potential confounding factors. Conclusions We found that the occupational noise had an effect on the hypertension and hearing loss of Chinese coal miners. And the occupational noise was an independent risk factor for hypertension and could increase the values of SBP and DBP. PMID:27076937

The purpose of this study is to determine the incidence of retinopathy of prematurity (ROP) and the maternal/neonatal risk factors at a tertiary care hospital in Oman, compared to other countries. A retrospective analysis of premature neonates born with gestational age (GA) 24-32 weeks at Sultan Qaboos University Hospital, Oman, from January 2007 to December 2010. Maternal and neonatal in-hospital course was retrieved. The incidence of ROP was reported. Risk factors analyses were performed using univariate and multivariate statistics. A total of 171 neonates (57% males, 43% females) were included for analysis. The incidence of ROP (any stage) was 69/171 (40.4%). Infants with ROP had significantly lower GA (27.7±2 weeks) compared to non-ROP group (30.2±1.7 weeks), P < 0.001),P < 0.001) and significantly lower birth weight (BW) (948 ± 242 g in ROP group vs. 1348 ± 283 g in non-ROP group;P < 0.001). Other significant risk factors associated with ROP were: small for GA, respiratory distress syndrome, requirement for ventilation, duration of ventilation or oxygen therapy, bronchopulmonary dysplasia, hyperglycemia, late onset sepsis (clinical or proven), necrotizing enterocolitis, patent ductus arteriosus, seizures, and number of blood transfusions. There was no significant difference in maternal characteristics between the ROP and non-ROP groups except that mothers of infants with ROP were found to be significantly younger. Logistic regression analysis revealed early GA, low BW, duration of Oxygen therapy, and late-onset clinical or proven sepsis as independent risk factors. ROP is still commonly encountered in neonatal practice in Oman and other countries. Early GA, low BW, and prolonged oxygen therapy continue to be the main risk factors associated with the occurrence of ROP in our setting. In addition, an important preventable risk factor identified in our cohort includes clinical or proven late-onset sepsis.

Background Reducing the exposure to risk factors for the prevention of cardio-cerebral vascular disease is a crucial issue. Few reports have described practical interventions for preventing cardiovascular disease in different genders and age groups, particularly detailed and specific cutpoint-based prevention strategies. Methods We collected the health examination data of 5822 subjects between 20 and 80 years of age. The administration of medical questionnaires and physical examinations and the measurement of blood pressure, fasting plasma glucose (FPG) and blood lipids [total cholesterol (TC), triglycerides (TG), high density lipoprotein–cholesterol (HDL-C), and low density lipoprotein-cholesterol (LDL-C)] were performed by physicians. Carotid ultrasound was performed to examine the carotid intima-media thickness (CIMT), which was defined as carotid atherosclerosis when CIMT ≥0.9 mm. Decision tree analysis was used to screen for the most important risk factors for carotid atherosclerosis and to identify the relevant cutpoints. Results In the study population, the incidence of carotid atherosclerosis was 12.20% (men: 14.10%, women: 9.20%). The statistical analysis showed significant differences in carotid atherosclerosis incidence between different genders (P<0.0001) and age groups (P<0.001). The decision tree analysis showed that in men, the most important traditional risk factors for carotid atherosclerosis were TC (cutpoint [CP]: 6.31 mmol/L) between the ages of 20–40 and FPG (CP: 5.79 mmol/L) between the ages of 41–59. By comparison, LDL-C (CP: 4.27 mmol/L) became the major risk factor when FPG ≤5.79 mmol/L. FPG (CP: 5.52 mmol/L) and TG (CP: 1.51 mmol/L) were the most important traditional risk factors for women between 20–40 and 41–59 years of age, respectively. Conclusion Traditional risk factors and relevant cutpoints were not identical in different genders and age groups. A specific gender and age group-based cutpoint strategy might contribute to preventing cardiovascular disease. PMID:25398126

The White House, the American Heart Association, the Agency for Healthcare Research and Quality, and the National Heart, Lung and Blood Institute have all recently acknowledged the need to disaggregate Asian American subgroups to better understand this heterogeneous racial group. This study aims to assess racial/ethnic differences in relative contribution of risk factors of gestational diabetes mellitus (GDM) among Asian subgroups (Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese), Hispanics, non-Hispanic blacks, and non-Hispanic whites. Pregnant women in 2007-2012 were identified through California state birth certificate records and linked to the electronic health records in a large mixed-payer ambulatory care organisation in Northern California (n = 24 195). Relative risk and population attributable fraction (PAF) for specific racial/ethnic groups were calculated to assess the contributions of advanced maternal age, overweight/obesity (Centers for Disease Control and Prevention (CDC) standards and World Health Organization (WHO)/American Diabetes Association (ADA) body mass index cut-offs for Asians), family history of type 2 diabetes, and foreign-born status. GDM was most prevalent among Asian Indians (19.3%). Relative risks were similar across all race/ethnic groups. Advanced maternal age had higher PAFs in non-Hispanic whites (22.5%) and Hispanics (22.7%). Meanwhile family history (Asian Indians 22.6%, Chinese 22.9%) and foreign-borne status (Chinese 40.2%, Filipinos 30.2%) had higher PAFs in Asian subgroups. Overweight/obesity was the most important GDM risk factor for non-Hispanic whites, Hispanics, Asian Indians, and Filipinos when the WHO/ADA cut-off points were applied. Advanced maternal age was the only risk factor studied that was modified by race/ethnicity, with non-Hispanic white and Hispanic women being more adversely affected than other racial/ethnic groups. Overweight/obesity, advanced maternal age, family history of type 2 diabetes, and foreign-borne status are important risk factors for GDM. The relative contributions of these risk factors differ by race/ethnicity, mainly due to differences in population prevalence of these risk factors. © 2015 John Wiley & Sons Ltd.

Numerous studies have shown the importance of physical activity in reducing the morbidity and mortality rates caused by cardiovascular disease (CVD). However, most of these studies emphasise little on the cumulative effect of CVD risk factors. Hence, this study investigates the association between physical exercise and cumulative CVD risk factors among adults in three different age groups. Using a sample of 7276 respondents drawn from community centers, the REDISCOVER team gathered information on physical activity, CVD risk factors (obesity, diabetes, hypertension, hypercholesterolemia, tobacco use) and socioeconomic and demographic variables in Malaysia. Because the study required medical examination, a convenience sampling frame was preferred in which all volunteers were included in the study. Fasting blood samples and anthropometric (height, weight and more) measurements were collected by trained staffs. Socio-demographic and physical activity variables were recorded through questionnaires. A Chi-square test was performed to identify the bivariate association between the covariates (socioeconomic variables, demographic variables and physical activity) and outcome variable. The association between the main exposure, physical activity, and the outcome variable, cumulative CVD risk factors, was assessed using an ordinal logistic regression model, controlling for socioeconomic status and demographic influences in three different age groups, 35-49, 50-64 and 65 and above. The mean age of participants is 51.8 (SD = 9.4). Respondents in the age groups of 35-49 (aORmoderate = 0.12; 95 % CI: 0.02 - 0.53 ) and 65 and above (aORhigh = 0.58; 95 % CI: 0.24, 0.78) showed a statistically significant inverse relationship between physical activity and cumulative CVD risk factors. However, this relationship was not significant among respondents in the 50-64 age group suggesting the possible influence of other variables, such as stress and environment. The statistically significant results show a negative association between physical exercise and cumulative CVD risk factors. However, the lack of a significant relationship in the 50-64 age group suggests the need to include other considerations in future studies, such as stress and environment.

To determine ethnic-specific temporal trends in cardiovascular risk factors in Ontario between 2001 and 2012. A population-based repeated cross-sectional study. Ontario, Canada. 219,276 participants of the Canadian Community Health Survey (205,326 white, 5620 South Asian, 4368 Chinese and 3962 black) during the period 2001 to 2012. Age-standardised ethnic-sex-specific prevalence of cardiovascular risk factors for three time periods: 2001-2004, 2005-2008 and 2009-2012 among Canada's four major ethnic groups: white, South Asian, Chinese and black. During the study period, the prevalence of diabetes increased 2.3-fold (p = 0.0001) among South Asian males and 1.9-fold (p = 0.02) among black females. The prevalence of obesity (body mass index ≥ 30 kg/m(2)) increased over time across all ethnic groups, with the largest relative increases observed among males of Chinese (2.1-fold increase, p = 0.04) and black (1.7-fold increase, p = 0.06) descent. The prevalence of hypertension increased the most among black females. Smoking prevalence decreased by more than 20% among South Asian, Chinese and white females. Overall, South Asian males and black males and females showed the greatest declines in cardiovascular health over the study period. We observed important ethnic differences in the temporal trends in cardiovascular risk factor profiles in Ontario. Awareness of the direction and magnitude of these risk factor trends may be useful in informing targeted strategies for preventing cardiovascular diseases in multiethnic populations.

It has been found that honey ameliorates cardiovascular risk factors in healthy individuals and in patients with elevated risk factors. The present study investigated the effect of natural honey on total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triacylglycerole, C-reactive protein (CRP), fasting blood glucose (FBG), and body weight in overweight individuals. There were 55 patients, overweight or obese, who were randomly recruited into the study and assigned into two groups: control group (17 subjects) and experimental group (38 subjects). Patients in the control group received 70 g of sucrose daily for a maximum of 30 days and patients in the experimental group received 70 g of natural honey for the same period. In the control and experimental groups, body weight, body mass index, body fat weight, total cholesterol, LDL-C, HDL-C, triacylglycerole, FBG, and CRP were measured before treatment and at day 31 after the commencement of treatment. Results showed that honey caused a mild reduction in body weight (1.3%) and body fat (1.1%). Honey reduced total cholesterol (3%), LDL-C (5.8), triacylglycerole (11%), FBG (4.2%), and CRP (3.2%), and increased HDL-C (3.3%) in subjects with normal values, while in patients with elevated variables, honey caused reduction in total cholesterol by 3.3%, LDL-C by 4.3%, triacylglycerole by 19%, and CRP by 3.3% (p < 0.05). It is our conclusion that consumption of natural honey reduces cardiovascular risk factors, particularly in subjects with elevated risk factors, and it does not increase body weight in overweight or obese subjects.

When considering early survival rates after pediatric cardiac surgery it is essential to adjust for risk linked to case complexity. An important but previously less well understood component of case mix complexity is comorbidity. The National Congenital Heart Disease Audit data representing all pediatric cardiac surgery procedures undertaken in the United Kingdom and Ireland between 2009 and 2014 was used to develop and test groupings for comorbidity and additional non-procedure-based risk factors within a risk adjustment model for 30-day mortality. A mixture of expert consensus based opinion and empiric statistical analyses were used to define and test the new comorbidity groups. The study dataset consisted of 21,838 pediatric cardiac surgical procedure episodes in 18,834 patients with 539 deaths (raw 30-day mortality rate, 2.5%). In addition to surgical procedure type, primary cardiac diagnosis, univentricular status, age, weight, procedure type (bypass, nonbypass, or hybrid), and era, the new risk factor groups of non-Down congenital anomalies, acquired comorbidities, increased severity of illness indicators (eg, preoperative mechanical ventilation or circulatory support) and additional cardiac risk factors (eg, heart muscle conditions and raised pulmonary arterial pressure) all independently increased the risk of operative mortality. In an era of low mortality rates across a wide range of operations, non-procedure-based risk factors form a vital element of risk adjustment and their presence leads to wide variations in the predicted risk of a given operation.

The aim of this study was to evaluate if the previous cardiac surgery (PCS) is the risk factor for short- and mid-term mortality following total aortic arch replacement in patients with Stanford type A aortic dissection. Between February 2009 and February 2012, a total of 384 patients who suffered Stanford type A aortic dissection involving aortic arch underwent total aortic arch replacement with frozen elephant trunk. Of these patients, 36 patients had PCS. Logistic regression was used to identify if the previous cardiac surgery was the risk factor for in-hospital mortality. Propensity score-matching (1:1 match) was used to yield patients from the primary surgery group who matched PCS group with respect to pre-operative clinical characteristics and post-operative complications. Survival analysis and differences between the two groups were performed by the Kaplan-Meier estimate and the log-rank test. The overall in-hospital mortality was 8%. Logistic multiple regression identified that cardiopulmonary bypass time≥ 300minutes (OR=12.05, p<0.001) and surgical period from symptom onset shorter than one week (OR=2.43, p=0.04) were final risk factors for in-hospital mortality and PCS was not the final risk factor. Of 36 patients with PCS, three patients died in the hospital and 33 patients were discharged from the hospital. Of these 33 patients, 32 patients matched primary surgery group successfully. During the follow-up period, two patients died in PCS group, one patient died in primary surgery group. The mean follow-up time was 35.38±14.12 months. The five-year survival was 96% for the primary surgery group. Previous cardiac surgery group five-year survival was 73%. Five-year survival was not significantly different between the two groups (p=0.84 log-rank test). PCS is not the risk factor for short- and mid-term mortality following total aortic arch replacement in patients with Stanford type A aortic dissection.

Background Understanding how urbanisation and rural-urban migration influence risk-factors for non-communicable disease (NCD) is crucial for developing effective preventative strategies globally. This study compares NCD risk-factor prevalence in urban, rural and migrant populations in China, Ghana, India, Mexico, Russia and South Africa. Methods Study participants were 39,436 adults within the WHO Study on global AGEing and adult health (SAGE), surveyed 2007–2010. Risk ratios (RR) for each risk-factor were calculated using logistic regression in country-specific and all country pooled analyses, adjusted for age, sex and survey design. Fully adjusted models included income quintile, marital status and education. Results Regular alcohol consumption was lower in migrant and urban groups than in rural groups (pooled RR and 95%CI: 0.47 (0.31–0.68); 0.58, (0.46–0.72), respectively). Occupational physical activity was lower (0.86 (0.72–0.98); 0.76 (0.65–0.85)) while active travel and recreational physical activity were higher (pooled RRs for urban groups; 1.05 (1.00–1.09), 2.36 (1.95–2.83), respectively; for migrant groups: 1.07 (1.0 -1.12), 1.71 (1.11–2.53), respectively). Overweight, raised waist circumference and diagnosed diabetes were higher in urban groups (1.19 (1.04–1.35), 1.24 (1.07–1.42), 1.69 (1.15–2.47), respectively). Exceptions to these trends exist: obesity indicators were higher in rural Russia; active travel was lower in urban groups in Ghana and India; and in South Africa, urban groups had the highest alcohol consumption. Conclusion Migrants and urban dwellers had similar NCD risk-factor profiles. These were not consistently worse than those seen in rural dwellers. The variable impact of urbanisation on NCD risk must be considered in the design and evaluation of strategies to reduce the growing burden of NCDs globally. PMID:25849356

Our aim was to assess the incidence and risk factors of the puerperal genital hematomas (PGH). We retrospectively reviewed recorded cases of PGH at Zekai Tahir Burak Research and Training Hospital, Ankara, Turkey, between January 2010 and 2014. Next three patients were chosen as control group. There were 47 cases of PGH with an incidence of 1 in 762 deliveries. Patients with PGH were younger, more likely to be nulliparous and had a greater weight gain during pregnancy than the control group. Patients with PGH had a longer first and second stage of labor than the control group. Mediolateral episiotomy and operative delivery were more frequently performed in patients with PGH than the control group. Neonates born to mothers with PGH were heavier than the control group (3525 ± 428 versus 3325 ± 579; p = 0.031). In the logistic regression model, nulliparity (OR: 8.68, 95% CI = 2.96-25.3), instrumental delivery (OR: 7.96, 95% CI = 1.37-49.0) and mediolateral episiotomy (OR: 6.67, 95% CI = 2.61-17.1) were factors which had an independent impact on risk of PGH. Nulliparity, instrumental delivery and mediolateral episiotomy are the main risk factors for hematomas.

To identify risk factors for common bile duct (CBD) stones in a south Indian population. Demographic characteristics and diet details were obtained from patients with isolated CBD stones (Gp I) and those with combined CBD and gallstones (Gp II) and age- and sex-matched controls. The risk factors were compared between the two groups. The demographic characteristics were similar between the two groups and matched controls. The significant risk factors for Gp I were infrequent consumption of green vegetable (odds ratio (OR), 2.3; p < 0.05), intake of tea/coffee (OR 3.3; p < 0.01) and less consumption of sugar (p < 0.01). For Gp II, the risk factors were frequent intake (>3 times per week) of spices (OR, 2.8; p < 0.05), fried foods (OR, 2.7; p < 0.05), tamarind (OR, 2.8; p < 0.01), and quantum of oil (p < 0.01) per month. Green vegetables (OR, 8.5; p < 0.00001) and sugar (9.5 + 4.2 vs. 13.8 + 11.2 g; p < 0.00001) were protective. Between the two groups, the risk factors for Gp II were less frequent green vegetable intake (OR: 6.4; p < 0.00001), more frequent spicy food (0-3 times per week) (OR, 7.0; p < 0.05), and higher monthly oil intake (251 + 105 vs. 292 + 89 mL; p < 0.05). CBD stones in both groups were associated with reduced intake of sugar and green vegetables. Our findings need to be validated in larger studies.

According to Jessor's Problem Behaviour Theory (PBT) and Moffitt's theory of adolescence-limited antisocial behaviour, adolescent risk behaviours cluster and can be predicted by various psychosocial factors including parent, peer and school attachment. This study tested the potential influence of the sociocultural, or macro-level, environment on the clustering and correlates of adolescent risk behaviour across 27 European and North American countries. Analyses were based on data from the 2009-10 Health Behaviour in School-aged Children (HBSC) study. Participants compromised 56,090 adolescents (M(age) = 15.5 years) who self-reported on substance use (tobacco, alcohol, cannabis) and early sexual activity as well as on psychosocial factors (parent, peer and school attachment). Multiple group confirmatory factor analyses (with country as grouping variable) showed that substance use and early sexual activity loaded on a single underlying factor across countries. In addition, multiple group path analyses (with country as grouping variable) showed that associations between this factor and parent, peer and school attachment were identical across countries. Cross-national consistencies exist in the clustering and psychosocial correlates of substance use and early sexual activity across western countries. While Jessor's PBT stresses the problematic aspects of adolescent risk behaviours, Moffitt emphasizes their normative character. Although the problematic nature of risk behaviours overall receives more attention in the literature, it is important to consider both perspectives to fully understand why they cluster and correlate with psychosocial factors. This is essential for the development and implementation of prevention programmes aimed at reducing adolescent risk behaviours across Europe and North America. © The Author 2014.

It has been proposed that mixed findings in studies investigating social cognition as a risk factor for violence in psychosis may be explained by utilizing a framework distinguishing between social-cognitive tests which measure relatively more basic operations (e.g. facial affect recognition) and measures of more complex operations (mentalizing, metacognition). The current study investigated which social cognitive and metacognitive processes are related to a violent history over and above illness-related deficits. Data from control participants (n = 33), patients with a psychotic disorder and no violent history (n = 27), and patients with a psychotic disorder in a forensic clinic (n = 23) were analyzed utilizing discriminant analysis. Metacognition and associative learning emerged as significant factors in predicting group membership between the three groups. In a follow-up analysis between only the patient groups, metacognitive Self-Reflectivity and Empathic Accuracy emerged as statistically significant predictors of group membership. The control group presented with higher levels of social cognitive and metacognitive capacity than patient groups, and the forensic patient group had lower levels than the non-forensic patient group. Our findings support previous research findings implying impaired metacognitive Self-Reflectivity in particular as a risk factor for violence. Copyright © 2018. Published by Elsevier B.V.

To evaluate the risk factors associated with an increased risk of symptomatic peripherally inserted central venous catheter (PICC)-related venous thrombosis. Retrospective analyses identified 2313 patients who received PICCs from 1 January 2012 to 31 December 2013. All 11 patients with symptomatic PICC-related venous thrombosis (thrombosis group) and 148 who did not have thromboses (non-thrombosis group) were selected randomly. The medical information of 159 patients (age, body mass index (BMI), diagnosis, smoking history, nutritional risk score, platelet count, leucocyte count as well as levels of D-dimer, fibrinogen, and degradation products of fibrin) were collected. Logistic regression analysis was undertaken to determine the risk factors for thrombosis. Of 2313 patients, 11 (0.47%) were found to have symptomatic PICC-related venous thrombosis by color Doppler ultrasound. Being bedridden for a long time (odds ratio [(OR]), 17.774; P=0.0017), D-dimer >5 mg/L (36.651; 0.0025) and suffering from one comorbidity (8.39; 0.0265) or more comorbidities (13.705; 0.0083) were the major risk factors for PICC-catheter related venous thrombosis by stepwise logistic regression analysis. Among 159 patients, the prevalence of PICC-associated venous thrombosis in those with ≥1 risk factor was 10.34% (12/116), in those with ≥2 risk factors was 20.41% (10/49), and in those with >3 risk factors was 26.67% (4/15). Being bedridden >72 h, having increased levels of D-dimer (>5 mg/L) and suffering from comorbidities were independent risk factors of PICC-related venous thrombosis. PMID:25664112

Furthermore a randomised controlled trial (RCT) will be designed to analyse the effect of a special intervention program. 40,000 employees of the Ford Motor Company, Visteon Company and Deutz Company in Germany will be included, monitored for ten years and the following primary endpoints will be investigated: 1. evaluation and comparison of established and newly developed risk-scores, 2. the relative impact of single and combined cardiovascular risk factors on cardiovascular diseases, 3. the influence of a novel occupationally integrated ambulant rehabilitation program in combination with a guideline oriented optimal drug therapy within a high risk group on the primary endpoint: risk reduction by, 4. the influence of this intervention on secondary endpoints: death, myocardial infarction and stroke, combined appearance of angina pectoris and hospitalisation, occurrence of cerebral circulatory disorder and hospitalisation, occurrence of peripheral occlusive arterial disease and hospitalisation and single cardiovascular risk factors and cost-benefit-analysis. Beginning with an cross sectional study there will be a systemic screening of cardiovascular risk profiles, of anthropometric data and different lifestyle-factors. Based on these data participants will be differentiated into three risk-groups according to the risk score of the European Society of Cardiology (risk of a lethal primary acute cardiovascular event: I < or = 1%; II > 1-< 5% and III > or = 5%). In the following longitudinal study different strategies will be applied: Group I: low risk (< 0.5% per year): repetition of the investigation after five and ten years. Group II: middle risk, (0.6% to 1.4% per year), repetition of the investigation every two years, instruction of the patients general practitioner (GP) with respect to a risk factor oriented and evidence based treatment. Group III: high risk, (> 1.5% per year or >15% within the next 10 years) will be randomised into two interventional groups. The first one, the intervention-group "PreFord" will perform an occupational integrated rehabilitation program (2,5-3 hours twice a week, for 15 weeks according to the BAR guidelines) with a following engagement in heart-groups and an annual repetition of the check-ups. The second group, the "classic" intervention-group will be treated evidence based in cooperation with their GP. As a result of this long term interventional study efficient, area wide implementable and economically feasible prevention concepts with special regards to operational healthcare will be developed and evaluated. Core elements will be exercise- and lifestyle-oriented concepts as well as guideline-based pharmacotherapy.

The incidence of cardiovascular disease (CVD) is increasing in industrialized countries. Preventive action is an important factor in minimizing CVD-associated morbidity and mortality. However, it is not known whether gender differences affect CVD or risk factor awareness influencing self-assessment of personal risk and preventive action. This study was performed to assess individual CVD and risk factor awareness, preventive action taken, and barriers to cardiovascular health. The study included 573 women and 336 men, randomly chosen to complete an anonymous questionnaire to assess individual CVD and risk factor awareness, preventive action taken, and barriers to cardiovascular health. The data were analyzed using SAS software. Cardiovascular disease was identified in 75% of patients, in both sexes, as the leading cause of death; however, both groups showed significant lack of knowledge about CVD risk factors. Type 2 diabetes was identified correctly in only 27.5%. Preventive action was linked more often to family members in 66.5% of women and 62.8% of men. The primary barrier to cardiovascular health in adults was incorrect assessment of personal CVD risk. More than half of female respondents (56.4%) and male respondents (52.7%) underestimated their risk of CVD. Knowledge about risk factors for CVD needs to be improved in members of both sexes. Because women, in particular, have difficulty in correctly assessing their personal CVD risk, future education programs are warranted to inform both women and men about CVD and its risk factors, thereby helping them to correctly assess their individual risk. However, greater effort is needed to inform men, compared with women, about the various ways in which to prevent CVD and to motivate them to take preventive action.

Nosocomial urinary tract infection (UTI) increases hospitalization, cost and morbidity. In this cohort study, we aimed to determine the incidence, risk factors, etiology and outcomes of UTIs in post-operative cardiac children. To this end, we studied all post-operative patients admitted to the Pediatric Cardiac Intensive Care Unit (PCICU) in 2012, and we divided the patients into two groups: the UTI (UTI group) and the non-UTI (control group). We compared both groups for multiple peri-operative risk factors. We included 413 children in this study. Of these, 29 (7%) had UTIs after cardiac surgery (UTI group), and 384 (93%) were free from UTIs (control group). All UTI cases were catheter-associated UTIs (CAUTIs). A total of 1578 urinary catheter days were assessed in this study, with a CAUTI density rate of 18 per 1000 catheter days. Multivariate logistic regression analysis demonstrated the following risk factors for CAUTI development: duration of urinary catheter placement (p<0.001), presence of congenital abnormalities of kidney and urinary tract (CAKUT) (p<0.0041) and the presence of certain syndromes (Down, William, and Noonan) (p<0.02). Gram-negative bacteria accounted for 63% of the CAUTI. The main causes of CAUTI were Klebsiella (27%), Candida (24%) and Escherichia coli (21%). Resistant organisms caused 34% of CAUTI. Two patients (7%) died in the UTI group compared with the one patient (0.3%) who died in the control group (p<0.05). Based on these findings, we concluded that an increased duration of the urinary catheter, the presence of CAKUT, and the presence of syndromes comprised the main risk factors for CAUTI. Gram-negative organisms were the main causes for CAUTI, and one-third of them found to be resistant in this single-center study.

A link between uric acid levels and cardiovascular diseases has been previously reported. Coronary artery calcium score (CACS) is a marker of atherosclerotic disease and a predictor of cardiovascular events. We sought to determine if serum uric acid level is an independent risk factor for the presence of calcium in coronary arteries. Four hundred and forty-two patients who were evaluated in the cardiology outpatient clinic for suspected coronary heart disease with a low-moderate risk for coronary artery disease were included in this observational case-controlled study. Serum uric acid levels were measured with colorimetric methods. CACS were performed using a 64-slice CT scanner. Patients were divided to 3 groups according to their CACS value (Group 1: CACS=0, Group 2: CACS 1-100, Group 3: CACS>100). The demographical characteristics and laboratory findings of 3 groups were similar, except age, fasting glucose levels and serum uric acid levels. Serum uric acid levels were found to increase significantly with increasing CACS (p=0.001). Patients were grouped according to presence CAC (CACS=0 and CACS≥1) and in the multiple regression analysis, age (OR, 1.11, 95% CI, 1.07-1.16), smoking (OR, 3.83, 95% CI, 2.06-7.09), serum uric acid levels (OR, 1.26, 95% CI, 1.04-1.54) and average 10-year total risk of Framingham risk score (OR, 1.13, 95% CI, 1.04-1.09) appeared as independent factors predictive of presence of CAC (p<0.05). Serum uric acid level is an independent risk factor for presence of coronary calcium. Moreover, increasing levels of serum uric acid are associated with increasing CACS.

We aimed to identify which personal and parental factors best explained all-cause mortality and cardiovascular disease (CVD). In 1996, data were collected on 2338 adult offspring of the participants in the 1972-1976 Renfrew and Paisley prospective cohort study. Recorded risk factors were assigned to 5 groups: mid-life biological and behavioural (BB), mid-life socioeconomic, parental BB, early-life socioeconomic and parental lifespan. Participants were followed up for mortality and hospital admissions to the end of 2011. Cox proportional hazards models were used to analyse how well each group explained all-cause mortality or CVD. Akaike's Information Criterion (AIC), a measure of goodness-of-fit, identified the most important groups. For all-cause mortality (1997 participants with complete data, 111 deaths), decreases in AIC from the null model (adjusting for age and sex) to models including mid-life BB, mid-life socioeconomic, parental BB, early-life socioeconomic and parental lifespan were 55.8, 21.6, 10.3, 7.3 and 5.9, respectively. For the CVD models (1736 participants, 276 with CVD), decreases were 37.8, 3.7, 6.7, 17.3 and 0.4. Mid-life BB factors were the most important for both all-cause mortality and CVD; mid-life socioeconomic factors were important for all-cause mortality, and early-life socioeconomic factors were important for CVD. Parental lifespan was the weakest factor. As mid-life BB risk factors best explained all-cause mortality and CVD, continued action to reduce these is warranted. Targeting adverse socioeconomic factors in mid-life and early life may contribute to reducing all-cause mortality and CVD risk, respectively. Published by the BMJ Publishing Group Limited.

Several studies have demonstrated that non-O blood groups subjects present an increased VTE risk as compared to those carrying O blood group. The aim of this study was to investigate the ABO blood groups influence on factor VIII (FVIII) activity, von Willebrand factor (VWF), and ADAMTS13 plasma levels in patients undergoing hemodialysis (HD). Patients undergoing HD (N=195) and 80 healthy subjects (control group) were eligible for this cross-sectional study. The ABO blood group phenotyping was performed by the reverse technique. FVIII activity was measured through coagulometric method, and VWF and ADAMTS13 antigens were assessed by ELISA. FVIII activity and VWF levels were significantly higher and ADAMTS13 levels was decreased in HD patients, as compared to healthy subjects (P < 0.001, in three cases). HD patients carrying non-O blood groups showed a significant increase in FVIII activity (P = 0.001) and VWF levels (P < 0.001) when compared to carriers of O blood group. However, no significant difference was observed in ADAMTS13 levels (P = 0.767). In the control group, increased in FVIII activity (P = 0.001) and VWF levels (P = 0.002) and decreased in ADAMTS13 levels (P = 0.005) were observed in subjects carrying non-O blood groups as compared to carriers of O blood group.Our data confirmed that ABO blood group is an important risk factor for increased procoagulant factors in plasma, as FVIII and VWF. Admitting the possible role of kidneys in ADAMTS13 synthesis or on its metabolism, HD patients were not able to increase ADAMTS13 levels in order to compensate the increase of VWF levels mediated by ABO blood groups. Considering that non-O blood groups constitute a risk factor for thrombosis, it is reasonable to admit that A, B and AB HD patients need a careful and continuous follow-up in order to minimize thrombotic events.

Early detection of cardiovascular disease (CVD) could initiate appropriate treatment and prevent progression. This study used impedance cardiography (ICG) waveform analysis with postural change to detect functional CVD in women older than 40 years with no history of CVD and >or=2 of the following risk factors: cigarette smoking, poor diet, physical inactivity, central adiposity, family history of premature CVD, hypertension, and dyslipidemia. A study group of 32 women underwent ICG in standing and supine positions. An age-matched control group had 20 women with an active lifestyle, no risk factors, and no history of CVD. All women in the control group had normal ICG data. All women in the study group had some abnormal ICG data, with 28 (87.5%) having multiple ICG abnormalities. ICG data indicated that 13 (40.6%) had ventricular dysfunction, 14 (43.8%) had high vascular resistive load, and 30 (93.8%) had elevated vascular pulsatile load. The data suggest that subclinical CVD, detectable by ICG, is prevalent in women older than 40 years with multiple risk factors. Abnormal ICG results could expedite the initiation of customized treatment as part of a preventive approach to CVD. (c) 2009 Wiley Periodicals, Inc.

Most of the studies dealing with Chronic Mechanical Irritation (CMI) and Oral Cancer (OC) only considered prosthetic and dental variables separately, and CMI functional factors are not registered. Thus, the aim of this study was to assess OC risk in individuals with dental, prosthetic and functional CMI. Also, we examined CMI presence in relation to tumor size. A case-control study was carried out from 2009 to 2013. Study group were squamous cell carcinoma cases; control group was patients seeking dental treatment in the same institution. 153 patients were studied (Study group n=53, Control group n=100). CMI reproducibility displayed a correlation coefficient of 1 (p<0.0001). Bivariate analysis showed statistically significant associations for all variables (age, gender, tobacco and alcohol consumption and CMI). Multivariate analysis exhibited statistical significance for age, alcohol, and CMI, but not for gender or tobacco. Relationship of CMI with tumor size showed no statistically significant differences. CMI could be regarded as a risk factor for oral cancer. In individuals with other OC risk factors, proper treatment of the mechanical injuring factors (dental, prosthetic and functional) could be an important measure to reduce the risk of oral cancer.

Background. Male hypogonadism is an endocrine disease characterized by low levels of serum testosterone and is closely related to the development of diabetes. The purpose of the present study was to observe the risk factors for hypogonadism in male patients with type 2 diabetes. Methods. A total of 213 patients with type 2 diabetes were enrolled and divided into a low total testosterone (TT) group (=75) and a normal TT group (=138). The patients' blood glucose, blood lipids, serum insulin, and sex hormones were measured. The correlations between the patients' metabolic index and sex hormone levels were analyzed. Results. Compared with the normal TT group, body mass index (BMI), fasting insulin (FINS), and HOMA insulin resistance index (HOMA-IR) levels were significantly higher, but the luteinizing hormone (LH) levels were significantly lower in the low TT group (p < 0.05). Correlation analyses found that TT was negatively correlated with BMI, waist circumference (WC), FINS, and HOMA-IR. TT was positively correlated with LH and follicle-stimulating hormone (FSH). Conclusions. Several risk factors of diabetes associated closely with hypogonadism. BMI, metabolic syndrome (MS), HOMA-IR, and LH are independent risk factors for hypogonadism in male patients with type 2 diabetes. PMID:27006953

C-reactive protein (CRP) is a biomarker of the inflammatory response, and it shows significant prognostic value for several types of solid tumors. The prognostic significance of CRP for lymphoma has not been fully examined. We evaluated the prognostic role of baseline serum CRP levels in patients with extranodal natural killer (NK)/T-cell lymphoma (ENKTL). We retrospectively analyzed 185 patients with newly diagnosed ENKTL. The prognostic value of the serum CRP level was evaluated for the low-CRP group (CRP≤10 mg/L) versus the high-CRP group (CRP>10 mg/L). The prognostic value of the International Prognostic Index (IPI) and the Korean Prognostic Index (KPI) were evaluated and compared with the newly developed prognostic model. Patients in the high-CRP group tended to display increased adverse clinical characteristics, lower rates of complete remission (P<0.001), inferior progression-free survival (PFS, P = 0.001), and inferior overall survival (OS, P<0.001). Multivariate analysis demonstrated that elevated serum CRP levels, age >60 years, hypoalbuminemia, and elevated lactate dehydrogenase levels were independent adverse predictors of OS. Based on these four independent predictors, we constructed a new prognostic model that identified 4 groups with varying OS: group 1, no adverse factors; group 2, 1 factor; group 3, 2 factors; and group 4, 3 or 4 factors (P<0.001). The novel prognostic model was found to be superior to both the IPI in discriminating patients with different outcomes in the IPI low-risk group and the KPI in distinguishing between the low- and intermediate-low-risk groups, the intermediate-low- and high-intermediate-risk groups, and the high-intermediate- and high-risk groups. Our results suggest that pretreatment serum CRP levels represent an independent predictor of clinical outcome for patients with ENKTL. The prognostic value of the new prognostic model is superior to both IPI and KPI.

Background. The etiology of attention-deficit hyperactivity disorder (ADHD) is complex.This study was conducted to evaluate the pregnancy-related maternal risk factors of ADHD. Methods. 164 ADHD children attending to Child and Adolescent Psychiatric Clinics compared with 166 normal children selected in a random-cluster method from primary schools. ADHD rating scale and clinical interview based on Schedule for Affective disorders and Schizophrenia for School-Aged Children (K-SADS) were used to diagnose ADHD cases and to select the control group. Results. The mean maternal age at pregnancy, duration of pregnancy, and the mean paternal age were alike in two groups. The ADHD children's mothers compared with those of control group had higher frequencies of somatic diseases, psychiatric disorders, and alcohol and cigarette exposure during the pregnancies (P < 0.01). Also birth by cesarean section was more common among mothers of ADHD children (P < 0.001). These factors plus trauma to the abdomen during pregnancy were significantly predictors of ADHD in children. Conclusions. Some pregnancy-related maternal factors may be considered as environmental risk factors for ADHD. Each of these factors considered in our study as a risk factor needs to be tested and confirmed through next methodologically appropriate researches in this field.

Risk factors for the childhood development of co-occurring internalizing and externalizing symptoms are not well understood, despite a high prevalence and poor clinical outcomes associated with this co-occurring phenotype. We examined inherited and environmental risk factors for co-occurring symptoms in a sample of children adopted at birth and their birth mothers and adoptive mothers (N = 293). Inherited risk factors (i.e., birth mothers’ processing speed and internalizing symptoms) and environmental risk factors (i.e., adoptive mothers’ processing speed, internalizing symptoms, and uninvolved parenting) were examined as predictors for the development of internalizing-only, externalizing-only, or co-occurring symptoms using structural equation modeling. Results suggested a unique pattern of predictive factors for the co-occurring phenotype, with risk conferred by adoptive mothers’ uninvolved parenting, birth mothers’ slower processing speed, and the birth mothers’ slower processing speed in tandem with adoptive mothers’ higher internalizing symptoms. Additional analyses indicated that when co-occurring-symptom children were incorporated into internalizing and externalizing symptom groups, differential risk factors for externalizing and internalizing symptoms emerged. The findings suggest that spurious results may be found when children with co-occurring symptoms are not examined as a unique phenotypic group. PMID:25851306

This study examined risk factor outcomes among patients who attended cardiac rehabilitation sessions, those who received traditional care, and those who attended Leap for Life workshops. A non-equivalent, three-group design was used in this observational study. Baseline and 12-month measurements were collected for 217 participants. Analysis of covariance was performed to determine differences between groups on outcome variables. The only significant finding was in participants with an initial high-density lipoprotein value of less than 40. High-density lipoprotein levels increased more in the cardiac rehabilitation group than in the traditional care group (30.54 to 37.48 versus 30.17 to 33.67 [F= 4.577, p = .035]). Based on these findings, a strong case can be made for the transition to more individually intense and focused risk factor modification strategies for patients in cardiac rehabilitation programs.

Currently, many scholars are concerned about the treatment of postoperative infection; however, few have completed multivariate analyses to determine factors that contribute to the risk of infection. Therefore, we conducted a multivariate analysis of a retrospectively collected database to analyze the risk factors for acute surgical site infection following lumbar surgery, including fracture fixation, lumbar fusion, and minimally invasive lumbar surgery. We retrospectively reviewed data from patients who underwent lumbar surgery between 2014 and 2016, including lumbar fusion, internal fracture fixation, and minimally invasive surgery in our hospital's spinal surgery unit. Patient demographics, procedures, and wound infection rates were analyzed using descriptive statistics, and risk factors were analyzed using logistic regression analyses. Twenty-six patients (2.81%) experienced acute surgical site infection following lumbar surgery in our study. The patients' mean body mass index, smoking history, operative time, blood loss, draining time, and drainage volume in the acute surgical site infection group were significantly different from those in the non-acute surgical site infection group (p < 0.05). Additionally, diabetes mellitus, chronic obstructive pulmonary disease, osteoporosis, preoperative antibiotics, type of disease, and operative type in the acute surgical site infection group were significantly different than those in the non-acute surgical site infection group (p < 0.05). Using binary logistic regression analyses, body mass index, smoking, diabetes mellitus, osteoporosis, preoperative antibiotics, fracture, operative type, operative time, blood loss, and drainage time were independent predictors of acute surgical site infection following lumbar surgery. In order to reduce the risk of infection following lumbar surgery, patients should be evaluated for the risk factors noted above.

This study used semi-parametric group-based modeling to explore unconditional and conditional trajectories of self-reported depressed mood from age 12 to 25. Drawing on data from the National Longitudinal Study of Adolescent Health (N=11,559), four distinct trajectories were identified: no depressed mood, stable low depressed mood, early high declining depressed mood, and late escalating depressed mood. Baseline risk factors associated with greater likelihood of membership in depressed mood trajectory groups compared to the no depressed mood group included being female, Black/African American, Hispanic/Latino American, or Asian American, lower SES, using alcohol, tobacco, or other drugs on a weekly basis, and delinquent behavior. Baseline protective factors associated with greater likelihood of membership in the no depressed mood group compared to the depressed mood trajectory groups included two-parent family structure, feeling connected to parents, peers, or school, and self esteem. With the exception of delinquent behavior, risk and protective factors also distinguished the likelihood of membership among several of the three depressed mood groups. The results add to basic etiologic research regarding developmental pathways of depressed mood in adolescence and young adulthood. PMID:18377115

Healthy middle-aged postmenopausal women have higher endothelium-dependent dilation and lower vasoconstrictor activity of endothelin-1 than men. Whether these sex-specific differences extend to patients with cardiovascular risk factors has not been investigated. The current study aimed to determine whether, in patients with cardiovascular risk factors, sex-specific differences exist in endothelium-dependent dilation and endothelin-1 activity. Forearm blood flow responses were measured by strain-gauge plethysmography during the intra-arterial infusion of acetylcholine, sodium nitroprusside, and the selective endothelin type A receptor blocker BQ-123 in 50 women and 64 men with cardiovascular risk factors. Acetylcholine and sodium nitroprusside induced a significant vasodilation in women and men alike (p < 0.01 for both). Also BQ-123 caused a significant vasodilation (p < 0.001) in both groups. The vasodilator response to acetylcholine was greater in women compared to men; however there were no differences in the response to sodium nitroprusside and BQ-123 (p = NS for both) between the two sex groups. Middle-aged women with cardiovascular risk factors have significantly higher endothelium-dependent dilation than middle-aged men; however, vascular endothelin 1 activity is similar in the two groups. These findings suggest that the presence of cardiovascular risk factors is associated with sex-specific effects on endothelium-dependent dilation but not on endothelin 1 activity. Further study is needed to confirm our findings and to characterize the mechanisms underlying this sex-specific regulation of endothelial function.

Objective: The purposes of this study were to determine the incidence of surgical site infections (SSI) and associated risk factors in patients undergoing isolated coronary artery bypass grafting (CABG) in our cardiac center during a 2-year period. Materials and Methods: Retrospective case-control analysis for 80 patients who underwent isolated cardiac surgery CABG. These patients were divided into the SSI study group (n = 40) and the noninfected control group (n = 40). Eight potential perioperative risk variables were compared between the two groups using univariate logistic regression analysis. Results: Univariate analysis was carried out for eight potential risk factors. The risk factors found to be significant were: Impaired estimated glomerular filtration rate (P = 0.011) and impaired left ventricular ejection fraction (P = 0.015). However, Factors found to have no significant influence on the incidence of SSIs were: Perioperative length of hospital stay (days), urgency of surgery, use of bilateral internal mammary artery (BIMA) grafting, prolonged cardiopulmonary bypass duration, elevated body mass index. Conclusions: Patients with comorbidities of impaired renal function and/or impaired left ventricular systolic function are at high risk of developing SSI. There appears to be a relationship between SSIs in CABG patients and impaired renal or LV function (low ejection fraction). CABG with BIMA grafting could be performed safely even in diabetics. Future studies should consider further scrutiny of these and other factors in relation to SSIs in a larger surgical population. PMID:27326347

We investigated the association between cardiovascular risk factors, including carotid intima-media thickness (CIMT), and future risk of mild cognitive impairment (MCI) and dementia in elderly subjects. We conducted a population-based prospective study as a part of the Korean Longitudinal Study on Health and Aging. Our study included 348 participants who were nondemented at the baseline (mean age, 71.7±6.3 years) and underwent cognitive evaluation at the 5-year follow-up. Baseline cardiovascular risk factors were compared according to the development of MCI or dementia during the study period. At the baseline evaluation, 278 subjects were cognitively normal and 70 subjects had MCI. Diagnoses of cognitive function either remained unchanged or improved during the study period in 292 subjects (nonprogression group), whereas 56 subjects showed progression of cognitive impairment to MCI or dementia (progression group). The progression group exhibited a higher prevalence of hypertension and greater CIMT compared with the nonprogression group. Other baseline cardiovascular risk factors, including sex, body mass index, diabetes mellitus, insulin resistance, total cholesterol, waist-to-hip ratio, visceral fat, pulse wave velocity, and ankle-brachial index, were not significantly different between 2 groups. The association between greater baseline CIMT and the progression of cognitive impairment was maintained after adjustment for conventional baseline risk factors of cognitive impairment. Greater baseline CIMT was also independently associated with the development of MCI in the subjects whose baseline cognitive function was normal. Greater baseline CIMT was independently associated with the risk of cognitive impairment, such as MCI and dementia in elderly subjects. © 2015 American Heart Association, Inc.

The incidence of gastric cancer has been increasing among elderly persons in Japan. This study aimed to clarify risk factors for postoperative complications in oldest old patients with gastric cancer. One-hundred ninety patients more than 75 years old with gastric cancer underwent gastrectomy between 2000 and 2011. Patients were classified into two groups: group A included 29 patients who were 85 years or older (oldest old patients), and group B included 161 patients who were 75-84 years of age. Perioperative parameters associated with complications were compared in each group. The preoperative estimated glomerular filtration rate was significantly lower in group A (p = 0.03). The two groups significantly differed in performance status (p = 0.018). Patients in group A received a lesser extent of lymph node dissection and had fewer lymph nodes excised. As a result, the duration of the operation was significantly shorter in group A. There were no significant differences in the frequency or grade of total complications or mortality between the two groups. Operative hemorrhage (>300 ml) and Hiroshima POSSUM (predicted morbidity risk >40) were risk factors in both groups A and B; the risk factors of preoperative serum albumin level and prognostic nutritional index (PNI) were specific to group A. Adjustments to the extent of surgery among oldest old patients most likely reduces the incidence of postoperative complications in this group. Preoperative serum albumin level and PNI are significant predictors of postoperative complications in oldest old patients with gastric cancer.

It has been reported that the incidence of post-operative segmental nerve palsy, such as C5 palsy, is higher in posterior reconstruction surgery than in conventional laminoplasty. Correction of kyphosis may be related to such a complication. The aim of this study was to elucidate the risk factors of the incidence of post-operative C5 palsy, and the critical range of sagittal realignment in posterior instrumentation surgery. Eighty-eight patients (mean age 64.0 years) were involved. The types of the disease were; 33 spondylosis with kyphosis, 27 rheumatoid arthritis, 17 athetoid cerebral palsy and 11 others. The patients were divided into two groups; Group P: patients with post-operative C5 palsy, and Group NP: patients without C5 palsy. The correction angle of kyphosis, and pre-operative diameter of C4/5 foramen on CT were evaluated between the two groups. Multivariate logistic regression analysis was used to determine the critical range of realignment and the risk factors affecting the incidence of post-operative C5 palsy. Seventeen (19.3 %) of the 88 patients developed C5 palsy. The correction angle of kyphosis in Group P (15.7°) was significantly larger than that in Group NP (4.5°). In Group P, pre-operative diameters of intervertebral foramen at C4/5 (3.2 mm) were significantly smaller than those in Group NP (4.1 mm). The multivariate analysis demonstrated that the risk factors were the correction angle and pre-operative diameter of the C4/5 intervertebral foramen. The logistic regression model showed a correction angle exceeding 20° was critical for developing the palsy when C4/5 foraminal diameter reaches 4.1 mm, and there is a higher risk when the C4/5 foraminal diameter is less than 2.7 mm regardless of any correction. This study has indicated the risk factors of post-operative C5 palsy and the critical range of realignment of the cervical spine after posterior instrumented surgery.

Nonmelanoma skin cancer (NMSC) is the commonest cancer in whites and its incidence is increasing worldwide. The prevalence of this cancer is predicted to equal that of all others combined and it was estimated that there were over 2 million cases diagnosed in the U.S.A. in 2004. Patients exhibit marked differences in clinical phenotype with variations in tumour numbers, rate of tumour accrual, site and histological subtype. Furthermore, patients are at increased risk of other cutaneous and noncutaneous cancers. The factors accounting for this variation are complex and still not completely understood. Clearly, ultraviolet light (UV) exposure is a major influence but its relationship to clinical phenotype is not yet clear. In addition, immunosuppression is a significant risk factor. Our group has identified high-risk groups for the development of further basal cell carcinoma (BCC), namely patients with truncal BCC and those presenting with tumour clusters. This presentation will concentrate on these clinical subgroups as well as immunosuppressed patients. These groups represent significant management challenges and are areas where novel, nonsurgical treatment options may make a significant clinical impact in patient care. The risk factors predisposing to these clinical phenotypes will be discussed, including genetic factors and UV exposure. Potential clinical applications, including predictive indices, will be considered.

The aim of the study was to identify risk factors for significant changes in emotional and behavioural problem load in a community-based cohort of Danish children aged 9-16 years, the risk factors being seven parental and two child-related adverse life events. Data on emotional and behavioural problems was obtained from parents filling in the Child Behavior Checklist (CBCL) when the child was 8-9 and again when 15 years old. Data on risk factors was drawn from Danish registers. Analysis used was logistic regression for crude and adjusted change. Parental divorce significantly raised the odds ratio of an increase in emotional and behavioural problems; furthermore, the risk of deterioration in problem behaviour rose significantly with increasing number of adverse life events. By dividing the children into four groups based on the pathway in problem load (increasers, decreasers, high persisters and low persisters), we found that children with a consistently high level of behavioural problems also had the highest number of adverse life events compared with any other group. Family break-up was found to be a significant risk factor. This supports findings in previous studies. The fact that no other risk factor proved to be of significance might be due to lack of power in the study. Children experiencing high levels of adverse life events are at high risk of chronic problem behaviour. Thus these risk factors should be assessed in daily clinical practice.

The purpose of this study was to assess the major risk factors for hypertension in oil workers, and investigate the effect of occupational stress on the incidence of hypertension after controlling for other risk factors. A prospective cohort approach was used following enrollment of 1354 oil workers. The occupational stress experienced by oil workers was higher than for the general population in China. By the end of the cohort study, 231 new cases of hypertension among the oil workers had been diagnosed. The cumulative incidence of hypertension was 17.06%. There were 44, 112, and 75 workers who developed hypertension in the low, intermediate, and high occupational stress groups, which represented a 12.0%, 15.6%, and 20.3% cumulative incidence, respectively (chi-square value = 9.812, p < 0.01). Multivariate Cox proportional hazard model analysis showed that type of work, cigarette smoking, excess body weight, and obesity were risk factors for hypertension ( p < 0.05). After risk factors such as type of work, cigarette smoking, alcohol consumption, and body mass index (BMI) were controlled, the hypertension risk (hazard ratio, HR) in the high occupational stress group was 1.549 (1.072-2.236) compared to the low exposure group, and 2.337 (1.191-4.585) in female subjects. Our study indicated that an increase in occupational stress was associated with an increased risk of hypertension after other factors were adjusted.

We aim to find the risk factors that influence the formation of bladder calculi in patients with benign prostate hyperplasia (BPH) and to reduce the surgical intervention related to bladder calculi.Between January 2015 and October 2016, 332 patients with BPH underwent surgical therapy were retrospectively evaluated. Patients with BPH were categorized into 2 groups: 94 patients with bladder calculi in group 1 and 238 patients without bladder calculi in group 2. Medical history, age, body mass index (BMI), total prostate specific antigen, total prostate volume (TPV), International Prostate Symptom Score (IPSS), intravesical prostatic protrusion (IPP), urodynamic parameters, and urine culture were compared between groups.There was no significant difference in the age, BMI, peak flow rate, and total IPSS between groups. TPV, total prostate specific antigen, and duration of BPH were significantly lower in group 1 than those in group 2. In addition, IPP was significantly higher in group 1 than group 2 (P < .001). Besides, after exclusion of patients with urinary retention and indwelling catheter, group 1 associated with a significantly higher preoperative positive rate of urine culture than that of group 2 (P = .046). Multivariate analysis indicated that IPP was a significant independent risk factor for the presence of bladder calculi.The incidence of bladder calculi in patients with BPH was proved to be closely associated with preoperative positive urine culture and longer IPP in our study. Furthermore, the IPP was presented to be an independent risk factor for the formation of bladder calculi. And early antibacterial therapy of urinary tract infection (UTI) may help to prevent the presence of bladder calculi in patients with BPH.

Cardiovascular disease (CVD) is the leading cause of mortality globally. Telephone-delivered interventions targeting cardiovascular risk factors are gaining popularity. This study is an evaluation of FrancoForme, a cardiovascular risk factor reduction program for the primary and secondary prevention of CVD among French-speaking patients of Eastern Ontario. This study reports on changes in cardiovascular risk factors, weekly exercise levels, and psychosocial characteristics including anxiety, depression, and quality of life upon program completion (3 months) and at 1 year after the start of the program. Repeated-measures analysis of variance was used to compare changes in outcomes between primary prevention risk groups (low, moderate, and high risk for CVD) and the secondary prevention group (ie, cardiac rehabilitation) at baseline, 3 months and 12 months. A total of 762 patients enrolled in FrancoForme between 2008 and 2015. At 3 months, all program completers (n = 507) experienced significant reductions for all cardiovascular risk factors except diastolic blood pressure. Minutes of self-reported exercise increased significantly by an average 90 minutes per week and all psychosocial variables improved. Significant group effects were observed across several risk factors. Among 12-month responders (n = 240), exercise, high-density lipoproteins, triglycerides, cholesterol, and all psychosocial variables were improved over baseline results. FrancoForme is unique in targeting both the primary and secondary prevention of CVD and removes several of the barriers to participating in a conventional CVD prevention program for French-speaking patients. FrancoForme is successful, receiving high satisfaction rates and resulting in significant improvements in cardiovascular risk factors, exercise, anxiety, and depression, as well as quality of life.

Spontaneous abortions were analyzed by the occupational exposure of women and their husbands, with data from the Finnish hospital discharge register and the national census. The occupations were grouped according to presumed exposure into seven categories: exposure to solvent; automobile exhaust fumes; polycyclic aromatic hydrocarbons; other chemicals; metals; textile dust; and animal microorganisms. The relative risks of spontaneous abortion were estimated with logistic regression analysis to adjust for potentially confounding factors. The broad exposure categories appeared, at most, to be weak risk factors of spontaneous abortion, because the relative risks of abortion were not significantly increased in any of themore » parental exposure groups. The analysis of detailed occupational categories showed some female and male occupations with an increased risk. The observations of increased risk related to laboratory work supported earlier findings. The high number of textile occupations with increased risk is also worth noting, and further investigations are necessary to confirm whether this is due to occupational hazards or other factors.« less

Hispanic women who are 50 years of age and older have been shown to be at increased risk of acquiring HIV infection due to age and culturally related issues. The purpose of our study was to investigate factors that increase HIV risk among older Hispanic women (OHW) as a basis for development or adaptation of an age and culturally tailored intervention designed to prevent HIV-related risk behaviors. We used a qualitative descriptive approach. Five focus groups were conducted in Miami, FL, with 50 participants. Focus group discussions centered around 8 major themes: intimate partner violence (IPV), perimenopausal-postmenopausal related biological changes, cultural factors that interfere with HIV prevention, emotional and psychological changes, HIV knowledge, HIV risk perception, HIV risk behaviors, and HIV testing. Findings from our study stressed the importance of nurses' roles in educating OHW regarding IPV and HIV prevention. PMID:23790277

Background: Genetically, predisposed children are considered as at-risk individuals for cardiovascular disease. In this study, we aimed to compare the frequency of four-lipid regulatory polymorphism in obese and normal-weight children with and without cardiometabolic risk factors. Materials and Methods: In this nested case–control study, 600 samples of four groups of participants consisted of those with normal weight with and without cardiometabolic risk factors and obese with and without cardiometabolic risk factors. Allelic and genotypic frequencies of GCKR (rs780094), GCKR (rs1260333), MLXIPL (rs3812316), and FADS (rs174547) polymorphisms were compared in the four studied groups. Results: Data of 528 samples were complete and included in this study. The mean (standard deviation) age of participants was 15.01 (2.21) years. Frequency of tt allele (minor allele) of GCKR (rs1260333) polymorphism was significantly lower in normal weight metabolically healthy participants than metabolically unhealthy normal weight (MUHNW) and obese children with and without cardiometabolic risk factor (P = 0.01). Frequency of ga allele of GCKR (rs780094) polymorphism was significantly higher in normal weight children with cardiometabolic risk factor than in their obese counterparts with cardiometabolic risk factor (P = 0.04). Frequency of cg and gg alleles (minor type) of MLXIPL (rs3812316) polymorphism in normal weight metabolically healthy participants was significantly higher than MUHNW (P = 0.04) and metabolically healthy obese children (P = 0.04). Conclusion: The findings of our study indicated that the minor allele of GCKR (rs1260333) single nucleotide polymorphisms (SNPs) could have pathogenic effect for obesity and cardiometabolic risk factors. Ga allele of GCKR (rs780094) SNPs had a protective effect on obesity. Minor alleles of MLXIPL (rs3812316) could have a protective effect for obesity and cardiometabolic risk factors. PMID:29531563

Purpose . Effectiveness of nonpharmacological multicomponent prevention delivered by trained volunteers (medical and psychology students), targeted at delirium risk factors in geriatric inpatients, was assessed at an internal medicine ward in Poland. Patients and Methods . Participants were recruited to intervention and control groups at the internal medicine ward (inclusion criteria: age ≥ 75, acute medical condition, basic orientation, and logical contact on admission; exclusion criteria: life expectancy < 24 hours, surgical hospitalization, isolation due to infectious disease, and discharge to other medical wards). Every day trained volunteers delivered a multicomponent standardized intervention targeted at risk factors of in-hospital complications to the intervention group. The control group, selected using a retrospective individual matching strategy (1 : 1 ratio, regarding age, gender, and time of hospitalization), received standard care. Outcome Measures. Hospitalization time, deaths, falls, delirium episodes, and antipsychotic prescriptions were assessed retrospectively from medical documentation. Results . 130 patients (38.4% males) participated in the study, with 65 in the intervention group. Antipsychotic medications were initiated less frequently in the intervention group compared to the control group. There was a trend towards a shorter hospitalization time and a not statistically significant decrease in deaths in the intervention group. Conclusion . Nonpharmacological multicomponent intervention targeted at delirium risk factors effectively reduced length of hospitalization and need for initiating antipsychotic treatment in elderly patients at the internal medicine ward.

Although the disease burden of listeriosis on population level is low, on individual level the impact is high, largely due to severe illness and a high case fatality. Identification of risk factors supports and specifies public health actions needed for prevention. We performed a case–control study to determine host- and food-related risk factors for non-perinatal listeriosis in the Netherlands. Patients with non-perinatal listeriosis reported between July 2008 and December 2013 were compared with controls from a periodic control survey who completed a questionnaire in the same period. Higher age, male sex, underlying disease, especially cancer and kidney disease, and use of immunosuppressive medicine were strong risk factors for acquiring non-perinatal listeriosis. Analysis of the food consumption in the group of cases and controls with underlying diseases did not reveal any high-risk food products. Information and advice should continue to be given to persons at risk of severe listeriosis. Univariate analyses indicate that patients using gastric acid inhibitors are at risk. It is worth adding these patients to the group of susceptible persons.

Multifactorial strategies that prevent or delay the onset or progress of cognitive decline and dementia are needed, and should include education regarding recognized risk factors. The current study sought to investigate whether older adults "at risk" of cognitive decline benefit from psychoeducation targeting healthy brain aging. 65 participants (mean age 64.8 years, SD 9.6) with a lifetime history of major depression; vascular risk as evidenced by at least one vascular risk factor; and/or subjective or objective memory impairment were allocated to weekly psychoeducation sessions or a waitlist control group. The small group sessions were conducted over ten weeks by a team of medical and allied health professionals with expertise in late-life depression and cognition. Sessions focused on modifiable risk factors for cognitive decline including vascular risk, diet, exercise, depression, anxiety and sleep disturbance, as well as providing practical strategies for memory and cognition. Both the psychoeducation and waitlist group completed a 20-item knowledge test at baseline and follow-up. Participants in the psychoeducation group were asked to complete follow-up self-report satisfaction questionnaires. Repeated measures ANOVA showed a significant interaction effect depicting improvements in knowledge associated with psychoeducation, corresponding to an improvement of 15% from baseline. Satisfaction data additionally showed that 92.3% of participants rated the program as "good" to "excellent", and over 90% suggested they would recommend it to others. A group-based psychoeducation program targeting healthy brain aging is effective in improving knowledge. Additionally, it is acceptable and rated highly by participants.

Individuals in the criminal justice system engage in behaviors that put them at high risk for HIV. This study sought to identify characteristics of individuals who are under community corrections supervision (eg, probation) and at risk for HIV. Approximately 25,000 individuals under community corrections supervision were assessed for HIV risk, and 5059 participants were deemed high-risk or no-risk. Of those, 1519 exhibited high sexual-risk (SR) behaviors, 203 exhibited injection drug risk (IVR), 957 exhibited both types of risk (SIVR), and 2380 exhibited no risk. Sociodemographic characteristics and drug of choice were then examined using univariate and binary logistic regression. Having a history of sexual abuse, not having insurance, and selecting any drug of choice were associated with all forms of HIV risk. However, the effect sizes associated with the various drugs of choice varied significantly by group. Aside from those common risk factors, very different patterns emerged. Female gender was a risk factor for the SR group but was less likely to be associated with IVR. Younger age was associated with SR, whereas older age was associated with IVR. Black race was a risk factor for SR but had a negative association with IVR and SIVR. Living in a shelter, living with relatives/friends, and being unemployed were all risk factors for IVR but were protective factors for SR. Distinct sociodemographic and substance use characteristics were associated with sexual versus injection drug use risk for individuals under community corrections supervision who were at risk for HIV. Information from this study could help identify high-risk individuals and allow tailoring of interventions.

Kidneys procured from the deceased hold great potential for expanding the donor pool. The aims of the present study were to investigate the post-transplant outcomes of renal allografts recovered from donors after cardiac death, to identify risk factors affecting the renal prognosis and to compare the long-term survival from donors after cardiac death according to the number of risk factors shown by expanded criteria donors. A total of 443 grafts recovered using an in situ regional cooling technique from 1983 to 2011 were assessed. To assess the combined predictive value of the significant expanded criteria donor risk criteria, the patients were divided into three groups: those with no expanded criteria donor risk factors (no risk), one expanded criteria donor risk factor (single-risk) and two or more expanded criteria donor risk factors (multiple-risk). Among the donor factors, age ≥50 years, hypertension, maximum serum creatinine level ≥1.5 mg/dL and a warm ischemia time ≥30 min were identified as independent predictors of long-term graft failure on multivariate analysis. Regarding the expanded criteria donors criteria for marginal donors, cerebrovascular disease, hypertension and maximum serum creatinine level ≥1.5 mg/dL were identified as significant predictors on univariate analysis. The single- and multiple-risk groups showed 2.01- and 2.40-fold higher risks of graft loss, respectively. Renal grafts recovered from donors after cardiac death donors have a good renal function with an excellent long-term graft survival. However, an increased number of expanded criteria donors risk factors increase the risk of graft loss. © 2016 The Japanese Urological Association.

The aim of this population-based study was to identify the factors associated with clinical outcomes in vemurafenib-treated patients and to evaluate outcomes across subgroups of patients with different risk profiles. Data were retrieved from the Dutch Melanoma Treatment Registry. Time to next treatment (TTNT) and overall survival (OS) of all metastatic melanoma patients who received vemurafenib between 2012 and 2015 were assessed using Kaplan-Meier estimates. A risk score was developed on the basis of all prognostic factors associated with TTNT and OS derived from multivariable Cox regression analyses. Patients were stratified according to the presence of prognostic risk factors by counting the number of factors, ranging from 0 to 6. A total of 626 patients received vemurafenib with a median follow-up of 35.8 months. The median TTNT and OS were 4.7 months [95% confidence intervals (CI): 4.4-5.1] and 7.3 months (95% CI: 6.6-8.0). The strongest prognostic factors were serum lactate dehydrogenase (LDH) level, Eastern Cooperative Oncology Group performance score, number of organ sites involved and brain metastases. Patients with a favourable risk profile (no risk factors) had a median TTNT and OS of 7.1 (95% CI: 5.8-8.5) and 15.4 months (95% CI: 10.0-20.9). The median OS more than halved for patients with greater than or equal to 2 risk factors compared with patients with no risk factors. The clinical outcomes of vemurafenib in metastatic melanoma patients with a favourable risk profile are comparable with the results of the trials. Combining prognostic factors into a risk score could be valuable to stratify patients into favourable and poor-prognosis groups.

The objectives of this study were to investigate risk factors and the incidence of ciprofloxacin resistance and extended-spectrum beta-lactamases (ESBL) in patients with acute bacterial prostatitis (ABP). We reviewed the medical records of 307 patients who were diagnosed with ABP between January 2006 and December 2015. The etiologic pathogens and risk factors for ciprofloxacin-resistant E. coli and ESBL-producing microbes, susceptibility to ciprofloxacin, and the incidence of ESBL in patients with ABP were described. History of prior urologic manipulation was an independent risk factor for ciprofloxacin-resistant (P = 0.005) and ESBL-producing microbes (P = 0.005). Advanced age (over 60 years) was an independent risk factor for ciprofloxacin-resistant microbes (P = 0.022). The ciprofloxacin susceptibility for Escherichia coli in groups without prior manipulation was documented 85.7%. For groups with prior manipulation, the susceptibility was 10.0%. Incidence of ESBL-producing microbes by pathogen was 3.8% for E. coli and 1.0% for Klebsiella pneumonia in the absence of manipulation group, and 20% and 33.3% in the presence of manipulation group, respectively. Initial treatment of ABP must consider patient's age and the possibility of prior manipulation to optimize patient treatment. With the high rate of resistance to fluoroquinolone, cephalosporins with amikacin, or carbapenems, or extended-spectrum penicillin with beta lactamase inhibitor should be considered as the preferred empirical ABP treatment in the patients with history of prior urologic manipulation.

Background Nasopharyngeal carcinoma (NPC) and other head and neck cancer (HNCA) types show a great epidemiological variation in different regions of the world. NPC has multifactorial etiology and many interacting risk factors are involved in NPC development mainly Epstein Barr virus (EBV). There is a need to scrutinize the complicated network of risk factors affecting NPC and how far they are different from that of other HNCA types. Methods 122 HNCA patients and 100 control subjects were studied in the region of the Middle East. Three types of HNCA were involved in our study, NPC, carcinoma of larynx (CL), and hypopharyngeal carcinoma (HPC). The risk factors studied were the level of EBV serum IgG and IgA antibodies measured by ELISA, age, sex, smoking, alcohol intake, histology, and family history of the disease. Results EBV serum level of IgG and IgA antibodies was higher in NPC than CL, HPC, and control groups (p < 0.01). NPC was associated with lymphoepithelioma (LE) tumors, males, regular alcohol intake, and regular smoking while CL and HPC were not (p < 0.05). CL and HPC were associated with SCC tumors (p < 0.05). Furthermore, NPC, unlike CL and HPC groups, was not affected by the positive family history of HNCA (p > 0.05). The serum levels of EBV IgG and IgA antibodies were higher in LE tumors, regular smokers, younger patients, and negative family history groups of NPC patients than SCC tumors, non-regular smokers, older patients and positive family history groups respectively (p < 0.05) while this was not found in the regular alcoholics (p > 0.05). Conclusion It was concluded that risk factors of NPC deviate much from that of other HNCA. EBV, smoking, alcohol intake, LE tumors, male patient, and age > 54 years were hot risk factors of NPC while SCC and positive family history of the disease were not. Earlier incidence, smoking, LE tumors, and negative family history of the disease in NPC patients were associated much clearly with EBV. It is proposed that determining the correct risk factors of NPC is vital in assigning the correct risk groups of NPC which helps the early detection and screening of NPC. PMID:19055849

This literature review aimed to determine the risk factors being used to identify children and young people who are at increased risk of engaging in self-harm and suicidal behaviour, so that optimal care can be provided for this patient group in children's medical ward settings. The two main themes that emerged were mental and neurodevelopmental disorders, and external factors. Management strategies to aid healthcare professionals in caring for this patient group were also identified. The review concludes by highlighting the need to provide healthcare professionals with continuing education about the mental health problems of children and young people, including risk factors and management strategies.

The burden of stroke is severe among African-Americans. Despite overall declines in the rate of stroke since 2000, outcomes are largely unimproved or have worsened for African-American men. Adverse psychosocial challenges may hinder adherence to a regimen of risk factor reduction. Focus group analysis was combined with a review of current published guidelines and epidemiologic evidence on risk factors to better understand stroke health disparities and potential policy solutions. Transcripts from three focus groups with ten African-American male stroke survivors under age 65 and their care partners (N = 7) were analyzed and compared with existing published data on (a) the burden of stroke (b) trends in clinical risk factors, and (c) trends in behavioral risk factors. Participants described myriad psychosocial barriers that impede reduction of risk indicators, including low trust in providers, poor social support, access difficulties, depression, and distress. In order to be effective, policies and programs must target mechanisms consistent with the challenges faced by African-American men. Infrastructure is needed to better identify and share practices effective for improving cardiovascular outcomes within specific racial and ethnic groups.

High rates of suicide attempts and domestic violence (DV) in women of reproductive age group have been reported from South India, but the association between them was not studied. Hence, this study was undertaken to assess whether DV is a risk factor for attempted suicide in married women of reproductive age group. A hospital-based case-control study with 77 incident cases of attempted suicide in married women of the age group of 18 to 45 years and 153 controls belonging to the same age group, without history of suicide attempt, was undertaken over a period of 6 months. Univariate and multivariate analyses were done. The crude odds ratio (cOR) for DV was found to be 6.15 (95% confidence interval [95% CI] = [2.95, 12.82], p value = .0001). Other statistically significant risk factors included younger age group (below 30 years); gross family income > Rs. 5,000; higher occupational status of spouse; having poor social support; having a family history of psychiatric disorders, substance use disorders, and suicide/suicide attempt; higher impulsiveness scores; having higher scores of stressful life events over the past 12 months, and alcohol use disorder in husband. Islamic faith was found to be a significant protective factor. On logistic regression, DV was found to be an independent risk factor for attempted suicide in this study population (adjusted OR = 3.79, 95% CI = [1.35, 10.62], p value = .011). Age groups, stressful life events, impulsiveness, and alcohol use disorder in husband were the confounders adjusted for in logistic regression along with other significant risk and protective factors. Significant dose-response relationship was also observed between DV and attempted suicide. In accordance with the stress-diathesis model for suicidal behavior, DV is found to be a stressor which precipitates suicide attempt in those with diathesis like family history of psychiatric disorders. Clinical, research, and policy implications of the findings are discussed.

In Zambia, adolescent girls and young women (AGYW) are disproportionately affected by human immunodeficiency virus (HIV), social, cultural and economic factors making them particularly vulnerable. This study was designed to understand the context in which AGYW are at risk and to identify perceived drivers of the epidemic and potential strategies to reduce HIV risk. Focus group discussions were conducted with AGYW in Zambian districts with the highest HIV prevalence from February through August 2016. The focus group guide addressed HIV risk factors and strategies for HIV prevention in AGYW. Focus group discussions were recorded, translated and transcribed, themes identified and responses coded. Results suggest that gender inequality undermined potentially protective factors against HIV among AGYW. Poverty and stigmatization were major barriers to accessing available HIV prevention services as well as primary risk factors for HIV infection. Sponsorship to support AGYW school attendance, programs for boys and girls to foster gender equality and financial assistance from the government of Zambia to support AGYW most in need were proposed as strategies to reduce HIV risk. Results highlight the utility of using community-based research to guide potential interventions for the affected population. Future research should explore the use of multilevel interventions to combat HIV among AGYW. PMID:29033613

Limited data are available regarding the relationship between age and the effect of HMG-CoA reductase inhibitor (statin) treatment. The aim of the present analysis was to evaluate the relationships between age, baseline patient characteristics, and pravastatin treatment with respect to the development of cardiovascular disease (CVD) in the Management of Elevated Cholesterol in the Primary Prevention Group of Adult Japanese (MEGA) study, a large-scale clinical study conducted in Japanese patients with mild or moderate hyperlipidaemia to evaluate the primary preventive effect of pravastatin against coronary heart disease. To compare the prevalence of CVD risk factors, the incidence of CVD in relation to each risk factor, and final values and changes in lipid parameters, the 7832 patients were classified into six age groups: <45, 45-49, 50-54, 55-59, 60-64 and ≥65 years. The relationship between pravastatin (10-20 mg/day) treatment efficacy and aging and the incidence of events in relation to the age groups were compared using the multivariable Cox proportional hazards model. The prevalences of diabetes mellitus and hypertension were higher in older men than in younger men, while the prevalences of smoking and obesity were higher in younger men. However, a similar difference in risk factors was not seen in women. High-density lipoprotein cholesterol was higher in women than in men across all age groups. Triglycerides were higher in younger men than in older men and all groups of women. The mean follow-up levels of total cholesterol and low-density lipoprotein cholesterol were lower in older patients than in younger patients. Pravastatin (10-20 mg/day) reduced the risk of CVD by about 30-40% across all age groups, and there was no difference between men and women. Of particular note in this analysis, CVD risk was markedly reduced in older women compared with younger women (53% vs 30% in women aged ≥65 vs ≥45 years). A similar satisfactory risk reduction for CVD was achieved with low-dose pravastatin in all men and in older women in particular, despite differences in the prevalence of risk factors.

This study reports on the clinical implementation of cell-free DNA (cfDNA) testing, contingent on the results of the combined test, in screening for fetal trisomies 21, 18 and 13 in two UK National Health Service hospitals. Women with a combined-test risk of ≥ 1:100 (high risk) were offered the options of chorionic villus sampling (CVS), cfDNA testing or no further testing and those with a risk of 1:101 to 1:2500 (intermediate risk) were offered cfDNA or no further testing. The objective of the study was to examine the factors affecting patient decisions concerning their options. Combined screening was performed in 6651 singleton pregnancies in which the risk for trisomies was high in 260 (3.9%), intermediate in 2017 (30.3%) and low in 4374 (65.8%). Logistic regression analysis was used to determine which factors among maternal characteristics, fetal nuchal translucency thickness (NT) and risk for trisomies were significant predictors of opting for CVS in the high-risk group and opting for cfDNA testing in the intermediate-risk group. In the high-risk group, 104 (40.0%) women opted for CVS; predictors for CVS were increasing fetal NT and increasing risk for trisomies, while the predictor against CVS was being of Afro-Caribbean racial origin (r = 0.366). In the intermediate-risk group, 1850 (91.7%) women opted for cfDNA testing; predictors for cfDNA testing were increasing maternal age, increasing risk for trisomies and university education, while predictors against cfDNA testing were being of Afro-Caribbean racial origin, smoking and being parous (r = 0.105). This study has identified factors that can influence the decision of women undergoing combined screening in favor of or against CVS and in favor of or against cfDNA testing. Copyright © 2014 ISUOG.

To expand the donor liver pool, ways are sought to better define the limits of marginally transplantable organs. The Donor Risk Index (DRI) lists 7 donor characteristics, together with cold ischemia time and location of the donor, as risk factors for graft failure. We hypothesized that donor hepatic steatosis is an additional independent risk factor. We analyzed the Scientific Registry of Transplant Recipients for all adult liver transplants performed from October 1, 2003, through February 6, 2008, with grafts from deceased donors to identify donor characteristics and procurement logistics parameters predictive of decreased graft survival. A proportional hazard model of donor variables, including percent steatosis from higher-risk donors, was created with graft survival as the primary outcome. Of 21,777 transplants, 5051 donors had percent macrovesicular steatosis recorded on donor liver biopsy. Compared to the 16,726 donors with no recorded liver biopsy, the donors with biopsied livers had a higher DRI, were older and more obese, and a higher percentage died from anoxia or stroke than from head trauma. The donors whose livers were biopsied became our study group. Factors most strongly associated with graft failure at 1 year after transplantation with livers from this high-risk donor group were donor age, donor liver macrovesicular steatosis, cold ischemia time, and donation after cardiac death status. In conclusion, in a high-risk donor group, macrovesicular steatosis is an independent risk factor for graft survival, along with other factors of the DRI including donor age, donor race, donation after cardiac death status, and cold ischemia time.

This study aimed to investigate the depression status among high-risk pregnancy women, and to analyze its relevant social and psychological factors. A total of 42 high-risk pregnancy women and 40 normal pregnancy women in a teaching hospital in Harbin city were followed up at time points of 32 - 36 weeks pregnancy, one week before labor, one week postpartum, and six weeks postpartum, respectively. During follow-up, the basic situation, social psychosocial factors of pregnancy women were collected and the depression of pregnancy women was measured by self-designed questionnaire and self-rating depression scale. The Edinburgh Postnatal Depression Scale (EPDS) was applied at timepoint of one week postpartum. Single factor analysis and the unconditional multivariate logistic regression were applied for analyzing the on the related social-psychosocial factors among high-risk pregnancy women. The age of high-risk pregnancy women was (31.0±5.6), and the age of normal pregnancy women was (30.5±3.8) (t=0.169, P>0.05). The results showed that the depression rate in high-risk pregnancy women was 45.2% (19/42), which was 25.0% (10/40) in normal pregnancy women, the difference was significant (χ2=3.671, P=0.045). The depression rates at different time points were 30.9% (13/42), 42.9% (18/42), 23.8% (10/42), 26.2% (11/42) in high-risk pregnancy women respectively, and 25.0% (10/40), 15.0% (6/40), 20.0% (8/40), 17.5% (7/40) in the control group respectively, the difference of the depression rates among groups at one week before labor was significant (χ2=7.680, P<0.01), the difference among groups at 32-36 weeks pregnancy (χ2=0.133, P=0.80), at one week postpartum (χ2=0.174, P=0.79) and at six weeks postpartum (χ2=0.903, P=0.43) were not significant. At one week postpartum and six weeks postpartum periods, the EPDS depression rate were 12.5% (4/32), 30.4% (7/23) in case group respectively, 8.3% (3/36), 22.9% (8/35) in control group respectively, the difference were not significant (χ2=0.319, 0.416, P=0.573, 0.519). There were significantly associations between the depression mood of one week before labor and the depressive symptoms of six weeks postpartum in both groups (r=0.824, 0.677, both P values were <0.05). The risk factors for maternal depression among high-risk pregnancy women were not ready for production (OR=2.73, P<0.01) and fearing of childbirth safety (OR=2.89, P<0.01). The depression date of high-risk pregnancy was high, especially at the time point one week before labor. Risk factors of maternal depression among high-risk pregnancy were "not ready for production" and "fear of childbirth safety".

Evaluate the effect of an intervention with rumba dance and nutrition education on the cardiovascular risk factors in a group of people with metabolic syndrome in a rural area of Colombia. Controlled, randomized clinical trial that included 59 people between 30 and 60 years of age with metabolic syndrome. The intervention group (n = 30) participated in a 12-week exercise program of aerobic rumba (60 minutes, 3 days per week) and muscle-strengthening work (30 minutes, twice a week). Each week the group also received two hours of nutrition education. The control group (n = 29) continued with conventional care. An assessment was made of the effect on the cardiovascular risk factors (physiological, metabolic, anthropometric, and nutritional) in the intervention group. The intervention group showed a reduction in systolic blood pressure (-10.0 mmHg; CI95%: -14.3 to -5.6, P < 0.001), diastolic blood pressure (-4.8 mmHg; CI95%: -8.4 to -1.1, P < 0.05) and overall cardiovascular risk at 10 years (-1.5%; CI95%: -2.7 to -0.3, P < 0.05). Furthermore, there was an increase in peak oxygen con-sumption (1.7 ml O2∙kg-1∙min-1; CI95%: 0.1 to 3.3, P < 0.05) and muscular strength (P < 0.001). Positive changes were also observed in body composition, caloric intake, and consumption of macro and micronutrients (P < 0.05). No differences were detected between metabolic variables in the two groups or in inflammatory markers (P < 0.05). An exercise program with rumba and muscular strengthening, combined with nutrition education, favorably modifies cardiovascular risk factors in people with metabolic syndrome.

Background Since the start of the 2009 influenza A pandemic (H1N1pdm), the World Health Organization and its member states have gathered information to characterize the clinical severity of H1N1pdm infection and to assist policy makers to determine risk groups for targeted control measures. Methods and Findings Data were collected on approximately 70,000 laboratory-confirmed hospitalized H1N1pdm patients, 9,700 patients admitted to intensive care units (ICUs), and 2,500 deaths reported between 1 April 2009 and 1 January 2010 from 19 countries or administrative regions—Argentina, Australia, Canada, Chile, China, France, Germany, Hong Kong SAR, Japan, Madagascar, Mexico, the Netherlands, New Zealand, Singapore, South Africa, Spain, Thailand, the United States, and the United Kingdom—to characterize and compare the distribution of risk factors among H1N1pdm patients at three levels of severity: hospitalizations, ICU admissions, and deaths. The median age of patients increased with severity of disease. The highest per capita risk of hospitalization was among patients <5 y and 5–14 y (relative risk [RR] = 3.3 and 3.2, respectively, compared to the general population), whereas the highest risk of death per capita was in the age groups 50–64 y and ≥65 y (RR = 1.5 and 1.6, respectively, compared to the general population). Similarly, the ratio of H1N1pdm deaths to hospitalizations increased with age and was the highest in the ≥65-y-old age group, indicating that while infection rates have been observed to be very low in the oldest age group, risk of death in those over the age of 64 y who became infected was higher than in younger groups. The proportion of H1N1pdm patients with one or more reported chronic conditions increased with severity (median = 31.1%, 52.3%, and 61.8% of hospitalized, ICU-admitted, and fatal H1N1pdm cases, respectively). With the exception of the risk factors asthma, pregnancy, and obesity, the proportion of patients with each risk factor increased with severity level. For all levels of severity, pregnant women in their third trimester consistently accounted for the majority of the total of pregnant women. Our findings suggest that morbid obesity might be a risk factor for ICU admission and fatal outcome (RR = 36.3). Conclusions Our results demonstrate that risk factors for severe H1N1pdm infection are similar to those for seasonal influenza, with some notable differences, such as younger age groups and obesity, and reinforce the need to identify and protect groups at highest risk of severe outcomes.

Carbapenem-resistant (CR), extreme-drug-resistant (XDR) & pan-drug-resistant (PDR) AB and PA (AB-PA) pose a huge clinical threat. This study reviews the impact of control groups on association of antecedent antibiotic use & acquisition of CR/XDR/PDR AB-PA. Studies investigating the role of antibiotics as risk factor for CR/XDR/PDR AB-PA acquisition in adult hospitalized patients from 1950 to 2016 were identified with databases. These were divided into 2 groups: antibiotic-resistant versus antibiotic-sensitive pathogens (Group I); versus no infection (Group II). A random effects model was performed. Eighty-five studies (46 AB, 38 PA, 1 both) with 22,396 patients were included. CR, XDR & PDR was investigated in 60, 20 and 2 studies respectively. Prior antibiotic exposure was associated with significant acquisition of CR/XDR/PDR AB-PA in both Groups I and II (p <0.05). Antibiotic classes implicated in both groups include aminoglycosides, carbapenems, glycopeptides and penicillins. Cephalosporin use was not associated with resistance in either group. Fluoroquinolones exposure was only associated with resistance in Group I but not Group II. Control groups play an important role in determining magnitudes of risk estimates for risk factor studies, hence careful selection is necessary. Antibiotic exposure increases acquisition of highly-resistant AB-PA, thus appropriate antibiotic use is imperative. Copyright © 2018. Published by Elsevier Ltd.

Risk factors for pressure ulcer development in critically Ill patients: a conceptual model to guide research.

PubMed

Benoit, Richard; Mion, Lorraine

2012-08-01

This paper presents a proposed conceptual model to guide research on pressure ulcer risk in critically ill patients, who are at high risk for pressure ulcer development. However, no conceptual model exists that guides risk assessment in this population. Results from a review of prospective studies were evaluated for design quality and level of statistical reporting. Multivariate findings from studies having high or medium design quality by the National Institute of Health and Clinical Excellence standards were conceptually grouped. The conceptual groupings were integrated into Braden and Bergstrom's (Braden and Bergstrom [1987] Rehabilitation Nursing, 12, 8-12, 16) conceptual model, retaining their original constructs and augmenting their concept of intrinsic factors for tissue tolerance. The model could enhance consistency in research on pressure ulcer risk factors. Copyright © 2012 Wiley Periodicals, Inc.

Lifestyle modification programs have improved the achievement of risk factor targets in a variety of clinical settings, including patients who have previously suffered a stroke or transient ischemic attack and those with multiple risk factors. Stenting Aggressive Medical Management for Prevention of Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) was the first vascular disease prevention trial to provide a commercially available lifestyle modification program to enhance risk factor control. We sought to determine the relationship between compliance with this program and risk factor control in SAMMPRIS. SAMMPRIS aggressive medical management included a telephonic lifestyle modification program provided free of charge to all subjects (n = 451) during their participation in the study. Subjects with fewer than 3 expected lifestyle-coaching calls were excluded from these analyses. Compliant subjects (n = 201) had  greater than or equal to 78.5% of calls (median % of completed/expected calls). Noncompliant subjects (n = 200) had less than 78.5% of calls or refused to participate. Mean risk factor values or % in-target for each risk factor was compared between compliant versus noncompliant subjects, using t tests and chi-square tests. Risk factor changes from baseline to follow-up were compared between the groups to account for baseline differences. Compliant subjects had better risk factor control throughout follow-up for low-density lipoprotein, systolic blood pressure (SBP), hemoglobin A1c (HgA1c), non-high-density lipoprotein, nonsmoking, and exercise than noncompliant subjects, but there was no difference for body mass index. After adjusting for baseline differences between the groups, compliant subjects had a greater change from baseline than noncompliant subjects for SBP did at 24 months and HgA1c at 6 months. SAMMPRIS subjects who were compliant with the lifestyle modification program had better risk factor control during the study for almost all risk factors. Published by Elsevier Inc.

The mathematical limits of genetic prediction for complex chronic disease.

Keyes, Katherine M; Smith, George Davey; Koenen, Karestan C; Galea, Sandro

Attempts at predicting individual risk of disease based on common germline genetic variation have largely been disappointing. The present paper formalises why genetic prediction at the individual level is and will continue to have limited utility given the aetiological architecture of most common complex diseases. Data were simulated on one million populations with 10 000 individuals in each populations with varying prevalences of a genetic risk factor, an interacting environmental factor and the background rate of disease. The determinant risk ratio and risk difference magnitude for the association between a gene variant and disease is a function of the prevalence of the interacting factors that activate the gene, and the background rate of disease. The risk ratio and total excess cases due to the genetic factor increase as the prevalence of interacting factors increase, and decrease as the background rate of disease increases. Germline genetic variations have high predictive capacity for individual disease only under conditions of high heritability of particular genetic sequences, plausible only under rare variant hypotheses. Under a model of common germline genetic variants that interact with other genes and/or environmental factors in order to cause disease, the predictive capacity of common genetic variants is determined by the prevalence of the factors that interact with the variant and the background rate. A focus on estimating genetic associations for the purpose of prediction without explicitly grounding such work in an understanding of modifiable (including environmentally influenced) factors will be limited in its ability to yield important insights about the risk of disease.

Summary Background and objectives The risk factors for CKD in different age groups remain unknown. This community-based study aimed to identify the risk factors for CKD in elderly and nonelderly patients. Design, setting, participants, & measurements A multistage sampling survey for CKD was conducted in 2007 in Kaohsiung County, an area with the highest prevalence of dialysis in the world. CKD was defined as proteinuria in at least the microalbuminuric stage or an estimated GFR (eGFR) of <60 ml/min per 1.73 m2. The factors for CKD in elderly and nonelderly patient groups were identified (with age 60 years as a cutoff value). Results The analyses included 3352 participants, of whom 687 had CKD. The weighted prevalence of CKD was 19.4% (95% confidence interval [CI], 18.0%–20.7%). Elderly patients typically presented with low eGFR and nonelderly patients, with proteinuria. Age, annual income, use of oral analgesics, metabolic syndrome, hyperuricemia, and hemoglobin were risk factors for CKD in both age groups. In elderly patients, risk factors were medical history of diabetes mellitus, CKD, stroke, and not using analgesic injection (odds ratios [95% CIs], 3.58 [2.06–6.22], 3.66 [1.58–8.43], 3.89 [1.09–13.87], 2.27 [1.21–4.17], respectively). In nonelderly patients, associated risk factors for CKD were gout, hepatitis B virus infection, and use of the Chinese herbal medicine Long Dan Xie Gan Tang (odds ratios [95% CIs], 3.15 [1.96–5.07], 1.66 [1.09–2.53], and 8.86 [1.73–45.45], respectively). Conclusions The risk factors for CKD vary by age. PMID:23085726

Social deprivation is associated with higher rates of preterm birth and subsequent infant mortality. Our objective was to identify risk factors for preterm birth in the UK's largest maternity unit, with a particular focus on social deprivation, and related factors. Retrospective cohort study of 39,873 women in Liverpool, UK, from 2002-2008. Singleton pregnancies were stratified into uncomplicated low risk pregnancies and a high risk group complicated by medical problems. Multiple logistic regression, and generalized additive models were used to explore the effect of covariates including area deprivation, smoking status, BMI, parity and ethnicity on the risk of preterm birth (34⁺⁰ weeks). In the low risk group, preterm birth rates increased with deprivation, reaching 1.6% (CI₉₅ 1.4 to 1.8) in the most deprived quintile; the unadjusted odds ratio comparing an individual in the most deprived quintile, to one in the least deprived quintile was 1.5 (CI₉₅ 1.2 to 1.9). Being underweight and smoking were both independently associated with preterm birth in the low risk group, and adjusting for these factors explained the association between deprivation and preterm birth. Preterm birth was five times more likely in the high risk group (RR 4.8 CI₉₅ 4.3 to 5.4), and there was no significant relationship with deprivation. Deprivation has significant impact on preterm birth rates in low risk women. The relationship between low socio-economic status and preterm births appears to be related to low maternal weight and smoking in more deprived groups.

Schizophrenia is associated with increased cardiovascular mortality. Although cardiovascular disease (CVD) risk prediction algorithms are widely in the general population, their utility for patients with schizophrenia is unknown. A primary care dataset was used to compare CVD risk scores (Joint British Societies (JBS) score), cardiovascular risk factors, rates of pre-existing CVD and age of first diagnosis of CVD for schizophrenia (n=1997) relative to population controls (n=215,165). Pre-existing rates of CVD and the recording of risk factors for those without CVD were higher in the schizophrenia cohort in the younger age groups, for both genders. Those with schizophrenia were more likely to have a first diagnosis of CVD at a younger age, with nearly half of men with schizophrenia plus CVD diagnosed under the age of 55 (schizophrenia men 46.1% vs. control men 34.8%, p<0.001; schizophrenia women 28.9% vs. control women 23.8%, p<0.001). However, despite high rates of CVD risk factors within the schizophrenia group, only a very small percentage (3.2% of men and 7.5% of women) of those with schizophrenia under age 55 were correctly identified as high risk for CVD according to the JBS risk algorithm. The JBS2 risk score identified only a small proportion of individuals with schizophrenia under the age of 55 as being at high risk of CVD, despite high rates of risk factors and high rates of first diagnosis of CVD within this age group. The validity of CVD risk prediction algorithms for schizophrenia needs further research. Copyright © 2014 Elsevier B.V. All rights reserved.

Yantai is a developed medium-sized coastal city in Eastern China, having a population of 1.6845 million. With the development of economy, some middle-aged and adolescent people (< 45 years) devote themselves to work and suffer from greater stress, which makes them ignore their own health. Moreover, they have unhealthy lifestyles and lack the knowledge of cardiovascular risk factors. To identify the risk factors for first acute myocardial infarction in middle-aged and adolescent people in Yantai, a developed medium-sized coastal city in Eastern China. A total of 154 consecutive patients with first acute myocardial infarction (< 45 years), were enrolled in case group, and 462 patients without myocardial infarction were enrolled in control group. Three controls with the same sex and age were matched to each case. The risk factors were identified with univariate and multivariate analysis. Unhealthy food habit (eating seafood and meanwhile drinking beer), hypertension, current smokers, self-perceived stress, diabetes mellitus, obesity, sleep insufficience, hypercholesterolaemia and fatigue were independent risk factors for first acute myocardial infarction (P < 0.05). Besides those recognized risk factors for cardiovascular disease (hypertension, hypercholesterolemia, diabetes mellitus and smoking), eating seafood and meanwhile drinking beer, self-perceived stress, sleep insufficience, obesity and fatigue were also the risk factors for first acute myocardial infarction in middle-aged and adolescent people in Yantai.

Suicide has been found to be prevalent among adolescents involved in bullying; however, there has been a lack of research examining whether the risk and protective factors of suicidal ideation and attempt are different among adolescents with different types of bullying involvement. The aims of this study were to examine the risk and protective factors of suicidal ideation and attempt among adolescents with different experiences of bullying involvement, victimization, and perpetration. A total of 4,533 adolescents participated in this study. Different groups of bullying involvement, victimization, and perpetration were determined through use of the Chinese version of the School Bullying Experience Questionnaire. The associations of suicidal ideation and attempt with possible risk factors (domestic violence, overweight, depression, anxiety, and alcohol abuse) and protective factors (family support and self-esteem) were examined using logistic regression analysis. Pure victims, pure perpetrators, and victim-perpetrators were more likely to report suicidal ideation and attempt than the neutral group. The risk and protective factors of suicidal ideation and attempt were different across adolescents with different experiences of bullying involvement, victimization, and perpetrators. The risk of suicide should be monitored among adolescents who are involved in any type of bullying. The risk and protective factors of suicide identified in this study should be taken into consideration in prevention and intervention programs for suicide in adolescents involved in bullying.

The objective of this study was to identify wheezing recurrences and related risk factors in two groups of infants with bronchiolitis: respiratory syncytial virus (RSV)+ and RSV- as determined by RSV enzyme immunoassay. A 1-year prospective cohort study was conducted with infants younger than 2 years old. Follow-up was made monthly, by a clinical visit and/or by telephone, checking the number of wheezing episodes per month and possible related risk factors. There were 96 subjects enrolled, of whom 77 reached complete follow-up: 36 were RSV+ (46.8%), and 41 were RSV- (53.2%). In the RSV+ group, there were 17 males (47%), vs. RSV- with 30 males (73%) (P < 0.05); 22 RSV+ (61%) were admitted to hospital, vs.14 RSV- (34%) (P < 0.05). Mean age was not significantly different in both groups. The mean number of recurrences was 3.36 episodes/infant/year in the RSV+ and 2.34 in the RSV- group (P = 0.06). Crude relative risk (RR) for a new recurrence of an obstructive episode was 1.33 (95% CI, 0.99-1.79). After adjustment for several potential confounders, the RR was 1.41 (95% CI, 1.03-1.93). Hospitalization stay was longer in the RSV+ than the RSV- group (P < 0.05). In the RSV+ group, patients who had been hospitalized showed more recurrences (4.18) than those with outpatient treatment (2.07) (P < 0.05); this difference did not exist in the RSV- group. The related risk factors for recurrent wheeze in the RSV- group were male gender, number of siblings, and daycare attendance (P < 0.05). In the RSV+ group, the risk of recurrent wheeze was only increased by admission to hospital during the acute bronchiolitis episode (P < 0.05). We speculate that there may be a higher rate of increased airway reactivity and/or preexisting diminished lung function in RSV+ infants requiring hospitalization for their initial illness. In conclusion, RSV-proven bronchiolitis, particularly in those infants who are hospitalized, is associated with a higher recurrence of wheezing episodes in the subsequent 12 months. Other factors appear to account for recurrent wheeze in the RSV- group. Copyright 2003 Wiley-Liss, Inc.

Urinary tract infection is the most common type of bacterial infection in kidney transplant procedures, with adverse effects on graft and patient survival. We aimed to evaluate the risk factors of recurrent urinary tract infection in renal transplant recipients and its impact on patient and graft survival. In a cohort of 1019 patients who were transplanted between 2000 and 2010 at Hamed Al-Essa Organ Transplant Center in Kuwait, 86% developed at least 1 episode of urinary tract infection, with only 6.2% of patients having recurrent infections. We compared patients with recurrent urinary tract infections (group 1) with those who had no recurrence (group 2) regarding their risk factors. Patients in group 1 were significantly younger than those in group 2 (34.9 ± 23 vs 42.8 ± 16 y; P < .001), with female preponderance (P < .001). The percentage of patients with thymoglobulin induction (21.5%) was significantly higher in group 1. Patients with pretransplant urologic problems experienced significantly more recurrent urinary tract infections (P < .001). Hepatitis C infections were significantly more prevalent among group 1 (10.8% vs 3.8%; P = .008). Long-term graft outcome (functioning and failed) were 78.5% and 21.5% in group 1 versus 85.1% and 13.9% in group 2 (P = .18). Patient outcomes (living and deceased donors) were 98.4% and 1.6% in group 1 versus 95.7% and 4.3% in group 2 (P = .187). Adult females, thymoglobulin induction, pretransplant urologic problems, and hepatitis C infection were the risk factors of recurrent urinary tract infection among our renal transplant patients. However, recurrence did not adversely affect graft or patient survival.

2014-01-01

Background To evaluate the effects of the lactic acid bacterium Lactobacillus salivarius on caries risk factors. Methods The study was performed in 64 healthy volunteers to evaluate the effects of L. salivarius-containing tablets on caries risk factors. The participants were divided randomly into four groups, and took tablets containing L. salivarius WB21, L. salivarius TI 2711, Ovalgen® DC (antibody against glucosyltransferase from Streptococcus mutans), or xylitol. Levels of mutans streptococci and lactobacilli, amount of salivary flow, salivary pH, and salivary buffering capacity were assessed before and after taking the tablets. Subsequently, a short-term administration trial using L. salivarius WB21-containing tablets was performed in eight healthy volunteers. The participants took L. salivarius WB21-containing tablets (2.0 × 109 colony forming units/day) for 2 weeks, and the numbers of mutans streptococci in saliva were counted. Results The levels of mutans streptococci seemed to decrease in the L. salivarius WB21, TI 2711, and Ovalgen® DC groups compared to the xylitol group, with no significant differences between the groups. Lactobacilli levels significantly increased in the L. salivarius WB21 and TI 2711 groups compared to the other groups. Concerning salivary flow and salivary pH, no significant differences were observed between the groups. The salivary buffering capacity significantly increased in the L. salivarius TI 2711 group (P = 0.003) and Ovalgen® DC group (P = 0.002) compared to the xylitol group. The short-term administration trial showed that the L. salivarius WB21-containing tablets significantly decreased the number of mutans streptococci (P = 0.039). Conclusion L. salivarius-containing tablets were suggested to increase resistance to caries risk factors. Trial registration UMIN000013160 (registration date: February 14, 2014). PMID:25178882

Epidemiological studies of the risk factors of cerebrovascular disease are of great interest, particularly the identification of factors which may be modified. Previous studies carried out in the Alcoi region of Alicante province, showed a high prevalence of cerebrovascular disease. The town of Bañeres was therefore chosen for confirmation of this data and identification of the frequency of vascular risk factors. To compare the group of patients with cerebrovascular disease with the remainder of the population interviewed. In a door-to-door study in Bañeres 1,832 people were interviewed as part of the Bañeres Project. The population aged over 45 years was interviewed and filled in a questionnaire for diagnosis of transient ischemic accidents. Arterial hypertension: estimated prevalence 500/1,000 inhabitants, relative risk 3.24; diabetes mellitus: estimated prevalence 195/1,000, relative risk 2.18; coronary artery disease: estimated prevalence 58/1,000, relative risk 1.88; peptic ulcer: estimated prevalence 75/1,000, relative risk 1.23; smoking: estimated prevalence 110/1,000, relative risk 0.46; complete arrhythmia: prevalence 73/1,000, relative risk 5.23. Family histories of cerebrovascular accident, arterial hypertension, diabetes and coronary artery disease were not significant. Arterial hypertension, diabetes mellitus and arrhythmia were significantly more prevalent amongst patients with vascular disease in our setting. We found no association with the other risk factors analyzed.

There are few studies examining development of acute kidney injury (AKI) in the various types of patients in intensive care units (ICUs). Presently described is evaluation of risk factors and development of AKI in different groups of ICU patients. Present study was performed in 3 different ICUs. Development of AKI was measured using Acute Kidney Injury Network (AKIN) classification system. Total of 300 patients who were treated in trauma, neurosurgery, or general ICU departments (due to head injury, aneurysmal subarachnoid hemorrhage [aSAH], or severe sepsis/septic shock, respectively) were assessed for incidence, risk factors, and development of AKI. AKI did not develop in aSAH patients when evaluated based on serum creatinine level; however, it was observed in 5% of aSAH patients according to volume adjusted creatinine (VACr) level. AKI developed in 76% of sepsis group, and in 20% of head injury group, based on AKIN classification, according to both serum and VACr levels. Incidence of AKI was significantly higher in sepsis group (p<0.001). Only use of vasopressor was significantly related to AKI development in sepsis and head injury groups. Mortality rate was 8%, 22%, and 42% in aSAH, head injury, and sepsis groups, respectively. AKI development and vasopressor use were significantly related to mortality in sepsis group. Despite similar characteristics and risk factors, there were fewer instances of AKI in aSAH group. Hypertension or hydration therapy used to treat vasospasm and polyuria due to cerebral salt-wasting syndrome may prevent aSAH patients from developing AKI.

Metabolic syndrome (MetS) increases the risk of morbidity and mortality from cardiovascular disease, and exercise training is an important factor in the treatment and prevention of the clinical components of MetS. The aim was to compare the effects of high-intensity interval training and steady-state moderate-intensity training on clinical components of MetS in healthy physically inactive adults. Twenty adults were randomly allocated to receive either moderate-intensity continuous training [MCT group; 60-80% heart rate reserve (HRR)] or high-intensity interval training (HIT group; 4 × 4 min at 85-95% peak HRR interspersed with 4 min of active rest at 65% peak HRR). We used the revised International Diabetes Federation criteria for MetS. A MetS Z-score was calculated for each individual and each component of the MetS. In intent-to-treat analyses, the changes in MetS Z-score were 1.546 (1.575) in the MCT group and -1.249 (1.629) in the HIT group (between-groups difference, P =  0.001). The average number of cardiometabolic risk factors changed in the MCT group (-0.133, P = 0.040) but not in the HIT group (0.018, P = 0.294), with no difference between groups (P = 0.277). Among apparently healthy physically inactive adults, HIT and MCT offer similar cardiometabolic protection against single MetS risk factors but differ in their effect on average risk factors per subject.

Objectives : To determine the risk factors associated with persistent airflow limitation in patients with asthma. Method s: This study was designed and carried out in the department of respiratory medicine, fourth People's Hospital of Jinan City, Shandong province, China between Jan 2012 and Dec 2012. Three hundred and six asthma patients participating in the study were divided into persistent airflow limitation group (PAFL) and no persistent airflow limitation group (NPAFL). The patients participated in pulmonary function tests and sputum induction examination. The clinical data including age, gender, onset age, disease course, smoking history, family history, regular corticosteroid inhalation, hospitalization history and presence of atopy were collected. Results : In 306 patients, 128 (40.5%) were included in PAFL group and 178(59.5%) in NPAFL group. Multivariate analysis demonstrated smoking (≥10 pack-years; OR, 7.1; 95% CI, 1.8 to 31.2), longer asthma duration (≥ 20years) (OR, 6.3; 95% CI, 1.7 to 28.5), absence of regular corticosteroid inhalation (OR, 3.5; 95% CI, 1.1 to 14.5) and neutrophil in induced sputum≥65% (OR, 1.8; 95% CI, 1.0 to 2.8) were independent risk factors for PAFL. Conclusions : Smoking, longer asthma duration and increased neutrophil in induced sputum are risk factors for PAFL, while regular corticosteroid inhalation is protective factor. Smoking cessation and regular corticosteroid inhalation may play an important role in preventing the occurrence of persistent airflow limitation group (PAFL).

Cardiovascular risk factors are prevalent in HIV-positive patients which places them at increased risk for cardiovascular disease (CVD). We aimed to determine the risk factors and risk assessment for CVD in HIV-positive patients with and without antiretroviral therapy. This was a cross-sectional study of HIV-positive patients attending the Lagos University Teaching Hospital, Nigeria. Anthropometric and blood pressure measurements were performed; fasting lipid profile, plasma glucose, homocysteine and hsCRP were determined, as well as prevalences and risk assessments. Statistical tests were used to compare the groups and p-value <0.05 was considered to be significant. 283 subjects were recruited for this study (100 HIV-positive treatment-naive, 100 HIV-positive treated and 83 HIV negative controls). Compared to the controls, mean (sd) values were significantly higher among HIV-treated subjects: waist circumference = 88.7 (10.4), p = 0.035; systolic bp= 124.9 (20.7), p = 0.014; glucose= 5.54 (1.7), p = 0.015; triglyceride= 2.0 (1.2), p < 0.001; homocysteine= 10.9 (8.9-16.2), p = 0.0003; while hsCRP= 2.9 (1.4-11.6), p = 0.002 and HDL-C = 0.9 (0.4), p = < 0.0001 were higher among the HIV-naïve subjects. Likewise, higher prevalences of the risk factors were noted among the HIV-treated subjects except low HDL-C (p < 0.001) and hsCRP (p = 0.03) which were higher in the HIV-naïve group. Risk assessment using ratios showed high risk for CVD especially in the HIV-naïve group. The median range for Framingham risk assessment was 1.0 - 7.5%. Risk factors and risk assessment for CVD are increased in HIV-positive patients with and without antiretroviral therapy. Routine evaluation and risk assessment for CVD irrespective of therapy status is necessary to prevent future cardiovascular events.

On-farm reduction of Salmonella carriage prevalence in pigs requires the identification of risk factors to direct interventions development. This study was designed to determine if split marketing of finishing pigs constitutes a risk factor for Salmonella infections, by comparing Salmonella prevalence in the first group of pigs selected for harvest ("first pull") versus the prevalence in the last group of pigs selected for harvest ("close out") from multiple commercial finishing lots. Nine paired samplings were conducted consisting in matched groups of pigs from individual barns as the first pull and the close out with a 4-week interval between groups. From each group, fecal and meat samples were collected, on-farm and at harvest, respectively. Fecal samples were selectively enriched, and analyzed for the presence of Salmonella, whereas meat juice samples were analyzed for the presence of antibodies against Salmonella. In 7/9 (77.8%) of the studied barns, an increase in Salmonella prevalence was observed, based on both bacteriologic and serologic analysis. Overall, there was an increase of 9.2% (p < 0.05) in bacteriologic prevalence, and 31.3% (p < 0.05) in serologic prevalence from first pull to close out groups. This study demonstrates that a significant increase in Salmonella prevalence occurs between the first and the last group of pigs harvested from finishing lots, with close out groups of market pigs posing a higher risk for Salmonella contaminations.

The suicide risk among young adults is related to multiple factors; therefore, it is difficult to predict and prevent suicidal behavior. We conducted the present study to reveal the most important factors relating to suicidal ideation in Japanese university students with major depressive episodes (MDEs) of major depressive disorder (MDD). The subjects were 30 Japanese university students who had MDEs of MDD, and were aged between 18 and 26 years old. They were divided into two groups - without suicide risk group (n=15), and with suicide risk group (n=15) - based on the results of the Mini-International Neuropsychiatric Interview. Additionally, healthy controls were recruited from the same population (n=15). All subjects completed the self-assessment scales including the Beck Depression Inventory 2nd edition (BDI-II), the Beck Hopelessness Scale (BHS), Rosenberg's Self-Esteem Scale (RSES), and SF-36v2™ (The Medical Outcomes Study 36-item short-form health survey version 2), and they were all administered a battery of neuropsychological tests. The RSES score of the suicide risk group was significantly lower than the RSES score of the without suicide risk group, whereas the BDI-II score and the BHS score were not significantly different between the two groups. The mean social functioning score on the SF-36v2 of the with suicide risk group was significantly lower than that of the without suicide risk group. The individual's self-esteem and social functioning may play an important role in suicide risk among young adults with MDEs of MDD.

There is important evidence on the beneficial effects of treatment of cardiovascular risk factors in terms of morbidity and mortality, but important challenges remain in motivating patients to adhere to their treatment regimen. This study aimed to describe the effectiveness of a quality improvement intervention that included information and regular encouragement by email or letter on cardiovascular risk factors for patients at high risk for cardiovascular disease. This randomized single-blind study included patients of both sexes aged between 45 and 80 years old who had increased cardiovascular risk. Patients were randomly allocated to either a usual care group (UCG) or advanced care group (ACG). Patients in the UCG received regular care while patients in the ACG received usual care plus regular information and encouragement on cardiovascular risk factors by email or letter. Visits for both groups were planned at 0, 3, and 6 months. The outcome measures were blood pressure, weight, body mass index (BMI), waist circumference (WC), and smoking status. Out of 178 eligible patients from one single primary care practice, 55 participated in the study, three of whom dropped out. After 6 months, there was a significant decrease in mean systolic and diastolic blood pressure in the UCG and ACG (P < 0.05). The decreases were already significant after 3 months, except for systolic blood pressure in the UCG. There was also a significant increase in the proportion of patients who met the target values for blood pressure in the UCG and ACG. There was a nonsignificant decrease of the average weight in the ACG, but significantly more patients lost weight in the UCG (P = 0.02). BMI, WC, and smoking status did not change in either group. This study found that there was a significant decrease of systolic and diastolic blood pressure in both study groups. Weight, BMI, WC, and smoking did not improve in either group. Information on cardiovascular risk factors and encouragement by means of letters or email did not provide additional benefits. Thus, effective patient empowerment probably requires more behaviorally sophisticated support to increase self-management, self-efficacy, and self-esteem in patients.

Achieving health equity is a priority of the World Health Organization; however, there is a scant amount of literature on this topic. As the underlying influences that determine health loss caused by risk factors are age-dependent, the aim of this paper is to examine how the risk factor rankings for health loss differ by age. Rankings were based on data obtained from the 2010 Global Burden of Disease study. Health loss (as measured by Disability Adjusted Life Years lost) by risk factor was estimated using Population-Attributable Fractions, years of life lost due to premature mortality, and years lived with disability, which were calculated for 187 countries, 20 age groups and both sexes. Uncertainties of the risk factor rankings were estimated using 1,000 simulations taken from posterior distributions The top risk factors by age were: household air pollution for neonates 0-6 days of age [95% uncertainty interval (UI): 1 to 1]; suboptimal breast feeding for children 7-27 days of age (95% UI: 1-1); childhood underweight for children 28 days to less than 1 year of age and 1-4 years of age (95% UI: 1-2 and 1-1, respectively); iron deficiency for children and youth 5-14 years of age (95% UI: 1-1); alcohol use for people 15-49 years of age (95% UI: 1-2); and dietary risks for people 50 years of age and older (95% UI: 1-1). Rankings of risk factors varied by sex among the older age groups. Alcohol and smoking were the most important risk factors among men 15 years of age and older, and high body mass and intimate partner violence were some of the most important risk factors among women 15 years of age and older. Our analyses confirm that the relative importance of risk factors is age-dependent. Therefore, preventing harms caused by various modifiable risk factors using interventions that target people of different ages should be a priority, especially since easily implemented and cost-effective public health interventions exist.

Objective To evaluate the impact of the renal dysfunction (RD) type and change of postoperative cardiac function on the risk of developing acute kidney injury (AKI) in patients who underwent cardiac valve surgery. Method Reversible renal dysfunction (RRD) was defined as preoperative RD in patients who had not been initially diagnosed with chronic kidney disease (CKD). Cardiac function improvement (CFI) was defined as postoperative left ventricular ejection function – preoperative left ventricular ejection function (ΔEF) >0%, and cardiac function not improved (CFNI) as ΔEF ≤0%. Results Of the 4,805 (94%) cardiac valve surgery patients, 301 (6%) were RD cases. The AKI incidence in the RRD group (n=252) was significantly lower than in the CKD group (n=49) (36.5% vs 63.3%, P=0.018). The AKI and renal replacement therapy incidences in the CFI group (n=174) were significantly lower than in the CFNI group (n=127) (33.9% vs 50.4%, P=0.004; 6.3% vs 13.4%, P=0.037). After adjustment for age, gender, and other confounding factors, CKD and CKD + CFNI were identified as independent risk factors for AKI in all patients after cardiac valve surgery. Multivariate logistic regression analysis showed that the risk factors for postoperative AKI in preoperative RD patients were age, gender (male), hypertension, diabetes, chronic heart failure, cardiopulmonary bypass time (every 1 min added), and intraoperative hypotension, while CFI after surgery could reduce the risk. Conclusion For cardiac valve surgery patients, preoperative CKD was an independent risk factor for postoperative AKI, but RRD did not add to the risk. Improved postoperative cardiac function can significantly reduce the risk of postoperative AKI. PMID:29184415

The risk factors and precautions of inpatient suicide were explored. Thirty suicide victims were drawn from the adverse event reports of suicidal act during hospitalization in a general hospital from 2008 to 2014. Data were gathered from the focus group interviews of twelve nurses who had experienced inpatient suicide. The data were analyzed by using analytical technique based on grounded theory, and software QSR NVIVO8 was used to aid the collation of data. Three main themes of risk factors about inpatient suicide emerged from the analysis: individual value, social factors and environmental factors. The individual value was categorized into different groups such as sense of guilt, hopelessness and low self-esteem. Social factors included two aspects of negative life events and social support. Three themes of precautions about inpatient suicide appeared in this study: evaluation, nursing and information exchange. Evaluation was elaborated from both physical and psychological assessments. This finding extends existing work of risk factors and precautions about inpatient suicide and brings new knowledge about the reasons why inpatients commit suicide.

Prevalence and risk factors of major depressive disorder in HIV/AIDS as seen in semi-urban Entebbe district, Uganda

2011-01-01

Background Not much is known about the risk factors of major depressive disorder (MDD) in HIV/AIDS in the African socio-cultural context. Therefore a study was undertaken to examine the prevalence and risk factors of MDD in HIV/AIDS in semi-urban Uganda. Methods A cross-sectional study was undertaken among 618 respondents attending two HIV clinics in Uganda. Results Prevalence of MDD was 8.1%. Factors associated with MDD at univariate analysis only were female gender, family history of mental illness, negative coping style, alcohol dependency disorder, food insecurity and stress; not associated with MDD were social support, neurocognitive impairment, CD4 counts and BMI. Factors independently associated with MDD were psychosocial impairment, adverse life events, post traumatic stress disorder, generalised anxiety disorder and life-time attempted suicide. Conclusion Psychological and social factors were the main risk factors of MDD among ambulatory HIV positive persons with no evidence for the role of the neurotoxic effects of HIV. Treatment approaches for MDD in this patient group should be modeled on those used among non-HIV groups. PMID:22208452

Is the risk of illness through consuming vegetables irrigated with reclaimed wastewater different for different population groups?

The use of reclaimed wastewater for irrigation of horticultural crops is commonplace in many parts of the world and is likely to increase. Concerns about risks to human health arising from such practice, especially with respect to infection with microbial pathogens, are common. Several factors need to be considered when attempting to quantify the risk posed to a population, such as the concentration of pathogens in the source water, water treatment efficiency, the volume of water coming into contact with the crop, and the die-off rate of pathogens in the environment. Another factor, which has received relatively less attention, is the amount of food consumed. Plainly, higher consumption rates place one at greater risk of becoming infected. The amount of vegetables consumed is known to vary among ethic groups. We use Quantitative Microbial Risk Assessment Modelling (QMRA) to see if certain ethnic groups are exposed to higher risks by virtue of their consumption behaviour. The results suggest that despite the disparities in consumption rates by different ethnic groups they generally all faced comparable levels of risks. We conclude by suggesting that QMRA should be used to assess the relative levels of risk faced by groups based on divisions other than ethnicity, such as those with compromised immune systems.

This pilot study evaluated the feasibility and preliminary effectiveness of a 10-week WhatsApp-based intervention aimed at enhancing health-related physical fitness components and cardiovascular disease (CVD) risk factors compared with a face-to-face condition. Participants (N.=32) were assigned to one of three groups: training group (N.=16), mobile group (N.=7) and control group (N.=9). Training group and mobile group performed the same training program, based on strength training with elastics bands and aerobic exercise, during 10 weeks; only the delivery mode differed. The mobile group increased handgrip strength, aerobic capacity and decreased systolic blood pressure and heart rate after exercise though there were no significant differences respect to control group. The training group decreased significantly systolic blood pressure (P=0.038), diastolic blood pressure (P=0.005), mean arterial pressure (P=0.006) and heart rate after exercise (P=0.002), respect to control group. Comparison between training and mobile group showed that WhatsApp-based physical activity intervention was less effective than face-to-face condition. The results indicate that the use of an online social network produced slight changes in some health-related physical fitness components and CVD risk factors.

We determined the incidences of the estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) subtypes among breast cancer cases in Sarawak, Malaysia and their correlation with various risk factors in the three ethnic groups: Chinese, Malay and native. Subtype status was ascertained for 1,034 cases of female breast cancer (93% of all cases diagnosed since 2003), and the age-standardized incidence rates (ASRs) of each subtype were inferred. Case-case comparisons across subtypes were performed for reproductive risk factors. We found 48% luminal A (ER+/PR+/HER2-), 29% triple-negative (ER-/PR-/HER2-), 12% triple-positive (ER+/PR+/HER2+) and 11% HER2-overexpressing (ER-/PR-/HER2+) subtypes, with ASRs of 10.6, 6.0, 2.8 and 2.8 per 100,000, respectively. The proportions of subtypes and ASRs differed significantly by ethnic groups: HER2-positive cases were more frequent in Malays (29%; 95% CI [23;35]) than Chinese (22%; [19;26] and natives (21%; [16;26]); triple-negative cases were less frequent among Chinese (23%; [20;27]) than Malays (33%; [27;39]) and natives (37%; [31;43]). The results of the case-case comparison were in accordance with those observed in western case series. Some uncommon associations, such as between triple-negative subtype and older age at menopause (OR, 1.59; p < 0.05), were found. The triple-negative and HER2+ subtypes predominate in our region, with significant differences among ethnic groups. Our results support the idea that the risk factors for different subtypes vary markedly. Westernized populations are more likely to have factors that increase the risk for the luminal A type, while risk factors for the triple-negative type are more frequent in local populations.

It has been unclear whether the risk factors for rotator cuff tears are the same at all ages or differ between young and older populations. In this study, we examined the risk factors for rotator cuff tears using classification and regression tree analysis as methods of nonlinear regression analysis. There were 65 patients in the rotator cuff tears group and 45 patients in the intact rotator cuff group. Classification and regression tree analysis was performed to predict rotator cuff tears. The target factor was rotator cuff tears; explanatory variables were age, sex, trauma, and critical shoulder angle≥35°. In the results of classification and regression tree analysis, the tree was divided at age 64. For patients aged≥64, the tree was divided at trauma. For patients aged<64, the tree was divided at critical shoulder angle≥35°. The odds ratio for critical shoulder angle≥35° was significant for all ages (5.89), and for patients aged<64 (10.3) while trauma was only a significant factor for patients aged≥64 (5.13). Age, trauma, and critical shoulder angle≥35° were related to rotator cuff tears in this study. However, these risk factors showed different trends according to age group, not a linear relationship.

Subdural hygroma (SDG) is a complication occurring after head trauma that may occur secondary to decompressive craniectomy (DC). However, the mechanism underlying SDG formation is not fully understood. Also, the relationship between the operative technique of DC or the decompressive effect and the occurrence and pathophysiology of SDG has not been clarified. Purpose of this study was to investigate the risk factors of SDG after DC in our series. From January 2004 to December 2008, DC was performed in 85 patients who suffered from traumatic brain injury. We retrospectively reviewed the clinical and radiological features. For comparative analysis, we divided the patients into 2 groups : one group with SDG after craniectomy (19 patients; 28.4% of the total sample), the other group without SDG (48 patients; 71.6%). The risk factors for developing SDG were then analyzed. The mean Glasgow Outcome Scale (GOS) scores at discharge of the groups with and without SDG were 2.8 and 3.1, respectively (p<0.0001). Analysis of radiological factors showed that a midline shift in excess of 5 mm on CT scans was present in 19 patients (100%) in the group with SDG and in 32 patients (66.7%) in the group without SDG (p<0.05). An accompanying subarachnoid hemorrhage (SAH) was seen in 17 patients (89.5%) in the group with SDG and in 29 patients (60.4%) in the group without SDG (p<0.05). Delayed hydrocephalus accompanied these findings in 10 patients (52.6%) in the group with SDG, versus 5 patients (10.4%) in the group without SDG (p<0.05). On CT, compression of basal cisterns was observed in 14 members (73.7%) in the group with SDG and in 18 members of the group without SDG (37.5%) (p<0.007). Furthermore, tearing of the arachnoid membrane, as observed on CT, was more common in all patients in the group with SDG (100%) than in the group without SDG (31 patients; 64.6%) (p<0.05). GOS showed statistically significant difference in the clinical risk factors for SDG between the group with SDG and the group without SDG. Analysis of radiological factors indicated that a midline shifting exceeding 5 mm, SAH, delayed hydrocephalus, compression of basal cisterns, and tearing of the arachnoid membrane were significantly more common in patients with SDG.

In this study, the risk perception level of each light pollution type was analyzed, and the effects of the variables (e.g., psychometric paradigm factor, trust in the government, etc.) on the process of the increase in the risk perception were analyzed. For the sample population (1096 persons) in Korea, the risk perception levels of each light pollution type and other environmental and health risk factors were compared, and the relative magnitude was examined. In addition, to test which variables affect the group with high-risk perception of each light pollution type, a logistic regression analysis was performed. For the group with highest risk perception of light pollution, the odds ratios (OR) of all psychometric paradigms (excluding controllability) increased compared to those of the group with low-risk perception. Additionally, the level showing the acquisition of information from the media and the recollection level of media criticism on each light pollution type showed a statistically significant increase. Especially, the risk perception of light trespass increased as trust in the government decreased. The significance of this study includes the finding that the public's risk perception of light pollution was significantly affected by the psychometric paradigm factors. Moreover, this study analyzed the differences of the variables that affect the increase in the risk perception of each light pollution type and provided a theoretical framework that can practically reflect the strategy for the risk communication of light pollution.

The aim of this study was to investigate whether or not the diabetes mellitus may be considered a risk factor for the HCV infection. The HCV seroprevalence was evaluated in 254 diabetic subjects, whose anamnestic data and risk factors are known, in comparison to 223 first-time blood donors, carefully age- and gender-matched. The statistical analysis showed that the studied groups belonged to the same population (Mann-Whitney U test) and that there were no significant differences between cases and controls as regards HCV prevalence (Yates corrected chi 2 test). The obtained data underline the importance of the control group selection, especially in the studies considering age-related pathologies. The authors disprove type 2 diabetes as a risk factor for the HCV infection and consider that this is a valid hypothesis only when the hepatitis C was unknown and not adequate prevention was used.

Gastrointestinal stromal tumors are the most frequent non-epithelial digestive tumors, being classified in the group of primitive mesenchymal tumors of the digestive tract. These tumors have a non predictable evolution and where stratified regarding the risk for malignant behavior in 4 categories: very low risk, low risk, intermediate risk and high risk. We performed a retrospective non randomised study including the patients with gastrointestinal stromal tumors treated in the Department of General Surgery and Liver Transplantation of Fundeni Clinical Institute in the period January 2002 - June 2007, to define the epidemiological, clinico-paraclinical, histological and especially evolutive features of the gastrointestinal stromal tumors from this group, with a special regard to the risk factors for their malignant behavior. The most important risk factors in gastrointestinal stromal tumors are the tumor size and the mitotic index, based on them being realised the classification of Fletcher in the 4 risk categories mentioned above. In our group all the local advanced or metastatic gastrointestinal stromal tumors, regardless of their location, were classified in the group of high risk for the malignant behavior. The gastric location and the epithelioid type were positive prognostic factors, and the complete resection of the tumor, an other important positive prognostic feature, was possible in about 80% of the cases, probably because the gastrointestinal stromal tumors in our study were diagnosed in less advanced evolutive situations, only about one third being metastatic and about 14% being locally advanced at the time of diagnose. The association with other neoplasias was in our cases insignificant, only 5% of the patients presenting concomitant malignant digestive tumors and 7.6% intraabdominal benign tumors. Gastrointestinal stromal tumors remain a challenge for the medical staff, regarding their diagnose and therapeutical management, the stratification of the risk for their malignant behavior being essential for the evolution of these patients.

This study presents a series of 34 sickle cell patients with one or more cerebrovascular accidents (CVA). Risk factors were studied in a subgroup of 19 patients whose clinical and biological characteristics were compared to those of a group of 444 sickle cell patients without CVA. The only risk factor discovered was a past history of purulent meningitis, which was significantly more frequent in sickle cell patients than in those without CVA (P < 0.0001). No biological or radiological factor affecting the risk of recurrence was found. The risk of recurrence, neurological defects or death after subsequent CVA justify long-term transfusion treatment in patients presenting with a second CVA. However our study shows that 10 patients who were not transfused after their first CVA had no recurrences, (median follow up = 7.9 years; 2-18 years), providing a basis for discussion on the indications of long-term transfusion therapy for sickle cell patients presenting with their first CVA.

Extranodal natural killer/T cell lymphoma, nasal type (ENKTL) is an aggressive disease with a poor prognosis, requiring risk stratification in affected patients. We designed a new prognostic model specifically for ENKTL to identify high-risk patients who need more aggressive therapy. We retrospectively reviewed 158 patients who were newly diagnosed with ENKTL. The estimated 5-year overall survival rate was 39.4 %. Independent prognostic factors included total protein (TP) <60 g/L, fasting blood glucose (FBG) >100 mg/dL, and Korean Prognostic Index (KPI) score ≥2. We constructed a new prognostic model by combining these prognostic factors: group 1 (64 cases (41.0 %)), no adverse factors; group 2 (58 cases (37.2 %)), one adverse factor; and group 3 (34 cases (21.8 %)), two or three adverse factors. The 5-year overall survival (OS) rates of these groups were 66.7, 23.0, and 5.9 %, respectively (p < 0.001). Our new prognostic model had a better prognostic value than did the KPI model alone (p < 0.001). Our proposed prognostic model for ENKTL, including the newly identified prognostic indicators, TP and FBG, demonstrated a balanced distribution of patients into different risk groups with better prognostic discrimination compared with the KPI model alone.

The aim of this study was to explore the independent prognostic factors related to postoperative recurrence-free survival (RFS) in patients with breast phyllodes tumors (PTBs). A retrospective analysis was conducted in Fudan University Shanghai Cancer Center. According to histological type, patients with benign PTBs were classified as a low-risk group, while borderline and malignant PTBs were classified as a high-risk group. The Cox regression model was adopted to identify factors affecting postoperative RFS in the two groups, and a nomogram was generated to predict recurrence-free survival at 1, 3, and 5 years. Among the 404 patients, 168 (41.6%) patients had benign PTB, 184 (45.5%) had borderline PTB, and 52 (12.9%) had malignant PTB. Fifty-five patients experienced postoperative local recurrence, including six benign cases, 26 borderline cases, and 22 malignant cases; the three histological types of PTB had local recurrence rates of 3.6%, 14.1%, and 42.3%, respectively. Stromal cell atypia was an independent prognostic factor for RFS in the low-risk group, while the surgical approach and tumor border were independent prognostic factors for RFS in the high-risk group, and patients receiving simple excision with an infiltrative tumor border had a higher recurrence rate. A nomogram developed based on clinicopathologic features and surgical approaches could predict recurrence-free survival at 1, 3, and 5 years. For high-risk patients, this predictive nomogram based on tumor border, tumor residue, mitotic activity, degree of stromal cell hyperplasia, and atypia can be applied for patient counseling and clinical management.

To evaluate the safety and efficacy of the hook wire system in the simultaneous localizations for multiple pulmonary nodules (PNs) before video-assisted thoracoscopic surgery (VATS), and to clarify the risk factors for pneumothorax associated with the localization procedure. Between January 2010 and February 2016, 67 patients (147 nodules, Group A) underwent simultaneous localizations for multiple PNs using a hook wire system. The demographic, localization procedure-related information and the occurrence rate of pneumothorax were assessed and compared with a control group (349 patients, 349 nodules, Group B). Multivariate logistic regression analyses were used to determine the risk factors for pneumothorax during the localization procedure. All the 147 nodules were successfully localized. Four (2.7%) hook wires dislodged before VATS procedure, but all these four lesions were successfully resected according to the insertion route of hook wire. Pathological diagnoses were acquired for all 147 nodules. Compared with Group B, Group A demonstrated significantly longer procedure time (p < 0.001) and higher occurrence rate of pneumothorax (p = 0.019). Multivariate logistic regression analysis indicated that position change during localization procedure (OR 2.675, p = 0.021) and the nodules located in the ipsilateral lung (OR 9.404, p < 0.001) were independent risk factors for pneumothorax. Simultaneous localizations for multiple PNs using a hook wire system before VATS procedure were safe and effective. Compared with localization for single PN, simultaneous localizations for multiple PNs were prone to the occurrence of pneumothorax. Position change during localization procedure and the nodules located in the ipsilateral lung were independent risk factors for pneumothorax.

Risk factors for bile leakage after hemihepatectomy are unknown. A prospectively maintained database review identified patients undergoing hemihepatectomy between 1 January 2009 and 30 September 2014. Patients were divided into B/C and non-B/C bile leakage groups. Risk factors for bile leakage were predicted and assessments of their impact on patients were made. Bile leakage occurred in 91 of the 297 patients (30.6%); 64 cases were classified as grade B bile leakage (21.5%) and three cases as grade C bile leakage (1.0%). Multivariate analysis confirmed that elevated preoperative alanine transaminase (ALT), positive bile culture during surgery, hilar bile duct plasty, bilioenteric anastomosis and laparoscopic surgery were risk factors for B/C grade bile leakage (P < 0.05). Percutaneous transhepatic biliary drainage (PTBD) and endoscopic nasobiliary drainage (ENBD) were protective factors for B/C grade bile leakage (P < 0.05). PTBD, ENBD and Kehr's T-tube drainage could reduce the drainage volume and duration of drainage after bile leakage (P < 0.05). The incidence of wound infection, abdominal infection, major complications and the Clavien classification system score in the B/C bile leakage group were higher than those in the non-B/C bile leakage group (P < 0.05). Patients in the B/C bile leakage group also required prolonged hospitalization (P < 0.05). The mortality of two groups was similar (P > 0.05). Patient with elevated preoperative ALT, positive bile cultures during surgery, hilar bile duct plasty, bilioenteric anastomosis and laparoscopic surgery are more likely to complicate bile leakage. We should use biliary drainage such as preoperative PTBD, ENBD or intraoperative Kehr's T-tube drainage to reduce and treat bile leakage in patients with high risk of bile leakage. © 2015 Royal Australasian College of Surgeons.

The study was to investigate the prevalence and risk factors of stress urinary incontinence (SUI) and its impact on the quality of life during pregnancy and 12 months after delivery. 866 women delivering their newborns at a tertiary hospital were recruited. All women were asked to complete several questionnaires including demographic and obstetric data, Short Form 12 health survey (SF-12), Urogenital Distress Inventory Short Form (UDI-6), and Incontinence Impact Questionnaire Short Form (IIQ-7). All women were interviewed via telephone to answer the same questionnaires at 12 months postpartum. There were 446 (51.5%) self-reported SUI women during pregnancy. Out of 560 women delivered vaginally, 70 (12.5%) had SUI at 12 months postpartum; in 306 women undergoing Cesarean delivery, 22 (7.2%) experienced SUI 12 months after delivery. Risk factors of SUI during pregnancy included body weight and body mass index at first visit. At 12 months postpartum, parity stood out as the risk factor of persistent SUI in vaginal delivery group, but no significant risk factor was found in Cesarean group. Women with SUI during pregnancy featured worse mental component summary (MCS) score of SF-12, compared to women without SUI. At 12 months postpartum, women with persistent SUI in vaginal delivery group had higher mean UDI-6 and IIQ-7 scores than those without SUI. Persistent SUI is more prevalent in the vaginal delivery group than Cesarean group. Both SUI during pregnancy and after childbirth have negative impact on the quality of life in women undergoing vaginal delivery. Copyright © 2018. Published by Elsevier B.V.

Background Polygenic obesity in Solid Organ Transplant (SOT) populations is considered a risk factor for the development of metabolic abnormalities and graft survival. Few studies to date have studied the genetics of weight gain in SOT recipients. We aimed to determine whether weighted genetic risk scores (w-GRS) integrating genetic polymorphisms from GWAS studies (SNP group#1 and SNP group#2) and from Candidate Gene studies (SNP group#3) influence BMI in SOT populations and if they predict ≥10% weight gain (WG) one year after transplantation. To do so, two samples (nA = 995, nB = 156) were obtained from naturalistic studies and three w-GRS were constructed and tested for association with BMI over time. Prediction of 10% WG at one year after transplantation was assessed with models containing genetic and clinical factors. Results w-GRS were associated with BMI in sample A and B combined (BMI increased by 0.14 and 0.11 units per additional risk allele in SNP group#1 and #2, respectively, p-values<0.008). w-GRS of SNP group#3 showed an effect of 0.01 kg/m2 per additional risk allele when combining sample A and B (p-value 0.04). Models with genetic factors performed better than models without in predicting 10% WG at one year after transplantation. Conclusions This is the first study in SOT evaluating extensively the association of w-GRS with BMI and the influence of clinical and genetic factors on 10% of WG one year after transplantation, showing the importance of integrating genetic factors in the final model. Genetics of obesity among SOT recipients remains an important issue and can contribute to treatment personalization and prediction of WG after transplantation. PMID:27788139

By analyzing the clinical features and risk factors in female patients with musculoskeletal symptoms of Southwest China, this report presents the initial analysis of characteristics in this region and compared with international evaluative criteria. Diagnosis of osteoporosis (OP) was made in female hospital patients age > or = 18 years admitted from January 1998 to December 2008 according to WHO definition. Case data were analyzed by symptoms, age, disease course and risk factors to reveal correlation with diagnosis of OP. Logistic regression was used to identify the risks of osteoporosis. A total of 4382 patients were included in the analysis of the baseline characteristics, among which 1455 in the OP group and 2927 in the non-OP group. The morbidity of OP is significantly increased in females' > or = 50 years. Both groups had symptoms related to pain and numbness; no significant difference was found in reported upper and lower back pain, or leg pain between two groups (p > 0.05). Neck, shoulder and arm pain, leg and arm numbness were more common in the non-osteoporosis group (p < 0.05, OR < 1, and upper limit of 95% CI of OR < 1). Hypertension, diabetes, hyperostosis were major risk factors for the patients with OP. The most common lifestyle-related risk factors for osteoporosis were smoking, body mass index, lack of physical activity and menopause. The present study offers the first reference data of the relationship between epidemiologic distribution of osteoporosis and associated factors in adults Chinese women. These findings provide a theoretical basis for its prevention and treatment in developing country.

Purpose Because current approaches to risk classification and treatment stratification for children with neuroblastoma (NB) vary greatly throughout the world, it is difficult to directly compare risk-based clinical trials. The International Neuroblastoma Risk Group (INRG) classification system was developed to establish a consensus approach for pretreatment risk stratification. Patients and Methods The statistical and clinical significance of 13 potential prognostic factors were analyzed in a cohort of 8,800 children diagnosed with NB between 1990 and 2002 from North America and Australia (Children's Oncology Group), Europe (International Society of Pediatric Oncology Europe Neuroblastoma Group and German Pediatric Oncology and Hematology Group), and Japan. Survival tree regression analyses using event-free survival (EFS) as the primary end point were performed to test the prognostic significance of the 13 factors. Results Stage, age, histologic category, grade of tumor differentiation, the status of the MYCN oncogene, chromosome 11q status, and DNA ploidy were the most highly statistically significant and clinically relevant factors. A new staging system (INRG Staging System) based on clinical criteria and tumor imaging was developed for the INRG Classification System. The optimal age cutoff was determined to be between 15 and 19 months, and 18 months was selected for the classification system. Sixteen pretreatment groups were defined on the basis of clinical criteria and statistically significantly different EFS of the cohort stratified by the INRG criteria. Patients with 5-year EFS more than 85%, more than 75% to ≤ 85%, ≥ 50% to ≤ 75%, or less than 50% were classified as very low risk, low risk, intermediate risk, or high risk, respectively. Conclusion By defining homogenous pretreatment patient cohorts, the INRG classification system will greatly facilitate the comparison of risk-based clinical trials conducted in different regions of the world and the development of international collaborative studies.

Adolescent African-American females are disproportionately impacted by HIV, thus there is a clear need to understand factors associated with increased HIV-risk behaviors among this vulnerable population. We sought to explore the association between a dopamine D4 receptor gene (DRD4), a genetic marker associated with natural variations in rewarding behaviors, and self-reported alcohol-use and sexual risk-behaviors, while controlling for other known correlates of risk-taking such as impulsivity, sensation seeking, and peer norms among a group of high-risk African American female adolescents to evaluate whether this biological factor enhances our understanding of patterns of risk in this vulnerable group.

While both sepsis-induced myocardial dysfunction (SIMD) and stress-induced cardiomyopathy (SICMP) are common in patients with sepsis, the pathogenesis of the 2 diseases is different, and they require different treatment strategies. Thus, we aimed to investigate risk factors and outcomes between the 2 diseases.This retrospective study enrolled patients diagnosed with sepsis or septic shock, admitted to intensive care unit via emergency department in Korea University Anam Hospital, and who underwent transthoracic echocardiography within the first 24 hours of admission.In all, 25 patients with SIMD and 27 patients with SICMP were enrolled. Chronic obstructive pulmonary disease and a history of heart failure (HF) were more prevalent in both the SIMD and SICMP groups than in the control group. In the SIMD and SICMP groups, levels of inflammatory cytokines were similar. Serum troponin level was significantly elevated in the SICMP and SIMD group compared to the control group. N-terminal pro-brain natriuretic peptide (NT pro-BNP) level was significantly elevated in the SIMD group compared to the SICMP group or control group. The in-hospital mortality rate in the SIMD and SICMP group was about 40%, showing increased trends compared with the control group. The in-hospital mortality rate was significantly increased in SIMD group with EF<30% than in SICMP group with EF<30%. In multiple logistic regression analysis, a past history of diabetes mellitus (DM) and HF was significantly associated with the incidence of SIMD. Younger age, elevated levels of NT pro-BNP, and positive result of blood culture also showed significant odds ratio regard to the occurrence of SIMD. However, only elevated lactate and troponin level were positively associated with the incidence of SICMP.The SIMD and SICMP had different risk factors. The risk factors of SIMD were younger age, history of DM, history of HF, elevated NT pro-BNP, and positive result of blood culture. The elevated levels of lactate and troponin were identified as risk factors of SICMP. More importantly, in-hospital mortality rate from SIMD and SICMP showed increased trend and worse outcome in SIMD group with reduced EF<30%. Thus, developing SIMD or SICMP reflected poor prognosis in sepsis or septic shock.

To explore the impact of racial and ethnic diversity on the performance of cardiac surgical risk models, the Chinese SinoSCORE was compared with the Society of Thoracic Surgeons (STS) risk model in a diverse American population. The SinoSCORE risk model was applied to 13 969 consecutive coronary artery bypass surgery patients from twelve American institutions. SinoSCORE risk factors were entered into a logistic regression to create a 'derived' SinoSCORE whose performance was compared with that of the STS risk model. Observed mortality was 1.51% (66% of that predicted by STS model). The SinoSCORE 'low-risk' group had a mortality of 0.15%±0.04%, while the medium-risk and high-risk groups had mortalities of 0.35%±0.06% and 2.13%±0.14%, respectively. The derived SinoSCORE model had a relatively good discrimination (area under of the curve (AUC)=0.785) compared with that of the STS risk score (AUC=0.811; P=0.18 comparing the two). However, specific factors that were significant in the original SinoSCORE but that lacked significance in our derived model included body mass index, preoperative atrial fibrillation and chronic obstructive pulmonary disease. SinoSCORE demonstrated limited discrimination when applied to an American population. The derived SinoSCORE had a discrimination comparable with that of the STS, suggesting underlying similarities of physiological substrate undergoing surgery. However, differential influence of various risk factors suggests that there may be varying degrees of importance and interactions between risk factors. Clinicians should exercise caution when applying risk models across varying populations due to potential differences that racial, ethnic and geographic factors may play in cardiac disease and surgical outcomes.

An understanding of factors influencing health in socioeconomic groups is required to reduce health inequalities. This study investigated combinations of health determinants associated with self-rated health (SRH), and their relative importance, in income-based groups. Cross-sectional data from year 15 (2000 - 2001) of the CARDIA study (Coronary Artery Risk Development in Young Adults, USA) - 3648 men and women (mean 40 years) - were split into 5 income-based groups. SRH responses were categorized as 'higher'/'lower'. Health determinants (medical, lifestyle, and social factors, living conditions) associated with SRH in each group were analyzed using classification tree analysis (CTA). Income and SRH were positively associated (p < 0.05). Data suggested an income-based gradient for lifestyle/medical/social factors/living conditions. Profiles, and relative importance ranking, of multi-domain health determinants, in relation to SRH, differed by income group. The highest ranking variable for each income group was chronic burden-personal health problem (<$25,000); physical activity ($25-50,000; $50-75,000; $100,000 +); and cigarettes/day ($75-100,000). In lower income groups, more risk factors and chronic burden indicators were associated with SRH. Social support, control over life, optimism, and resources for paying for basics/medical care/health insurance were greater (%) with higher income. SRH is a multidimensional measure; CTA is useful for contextualizing risk factors in relation to health status. Findings suggest that for lower income groups, addressing contributors to chronic burden is important alongside lifestyle/medical factors. In a proportionate universalism context, in addition to differences in intensity of public health action across the socioeconomic gradient, differences in the type of interventions to improve SRH may also be important.

Abstract To explore the characteristics and relevant risk factors of periodontal disease (PD) among hemodialysis patients. Uremic patients on maintenance hemodialysis from November 2015 to March 2016 were retrospectively reviewed. Patients were divided into a PD group and a non-PD group. Demographic and laboratory data were collected and analyzed. In all, 136 uremic patients (79 males and 57 females, aged 50.8 ± 15.3 years) on maintenance hemodialysis were included in this study. The incidence of PD increased with age. Hemodialysis patients most likely developed PD if they were male, smokers, or diabetic (P = .009, <.001, and <.001, respectively). Patients brushing their teeth twice daily had significantly less chance of developing PD as compared with those only brushing once daily (P < .001). Hemodialysis patients in the PD group had significantly higher levels of total cholesterol, high-sensitivity C-reactive protein, fasting blood glucose, and peripheral white blood cell counts, compared with the non-PD group (all P < .001). Logistic regression analysis revealed that diabetes, total cholesterol, high-sensitivity C-reactive protein, and peripheral white blood cell count were independent risk factors for developing PD, whereas teeth brushing twice daily and serum calcium were favorable factors for maintenance hemodialysis patients against PD. Identification of risk factors provides a theoretical basis for prevention and improvement of PD among maintenance hemodialysis patients. PMID:28858105

Little is known about the patterns of risk factors experienced by communities of color and how diverse community contexts shape the health trajectory of women from the early childhood period to the time of their pregnancies. Thus, we conducted a focus group study to identify social risks over the life course that contribute to maternal and child health from the perspective of community members residing in low income urban areas. Ten community-based participatory focus groups were conducted with residents from selected communities in Tampa, Florida, from September to November 2013. We used the life course perspective to illuminate and explain the experiences reported by the interviewees. A total of 78 residents participated in the focus groups. Children and adolescents' health risks were childhood obesity, lack of physical activity, and low self-esteem. Women's health risks were low self-esteem, low educational level, low health literacy, inadequate parenting skills, and financial problems. Risks during pregnancy included stress, low self-esteem, inadequate eating patterns, lack of physical activity, healthcare issues, lack of social support, and lack of father involvement during pregnancy. Multiple risk factors contribute to maternal and child health in low income communities in Tampa Bay. The intersection of risk factors in different life periods suggest possible pathways, cumulative, and latent effects, which must be considered in future longitudinal studies and when developing effective maternal and child health programs and policies.

Evidence suggests an elevated prevalence of cardiometabolic risks among persons with spinal cord injury (SCI); however, the unique clustering of risk factors in this population has not been fully explored. The purpose of this study was to describe unique clustering of cardiometabolic risk factors differentiated by level of injury. One hundred twenty-one subjects (mean 37 ± 12 years; range, 18-73) with chronic C5 to T12 motor complete SCI were studied. Assessments included medical histories, anthropometrics and blood pressure, and fasting serum lipids, glucose, insulin, and hemoglobin A1c (HbA1c). The most common cardiometabolic risk factors were overweight/obesity, high levels of low-density lipoprotein (LDL-C), and low levels of high-density lipoprotein (HDL-C). Risk clustering was found in 76.9% of the population. Exploratory principal component factor analysis using varimax rotation revealed a 3-factor model in persons with paraplegia (65.4% variance) and a 4-factor solution in persons with tetraplegia (73.3% variance). The differences between groups were emphasized by the varied composition of the extracted factors: Lipid Profile A (total cholesterol [TC] and LDL-C), Body Mass-Hypertension Profile (body mass index [BMI], systolic blood pressure [SBP], and fasting insulin [FI]); Glycemic Profile (fasting glucose and HbA1c), and Lipid Profile B (TG and HDL-C). BMI and SBP formed a separate factor only in persons with tetraplegia. Although the majority of the population with SCI has risk clustering, the composition of the risk clusters may be dependent on level of injury, based on a factor analysis group comparison. This is clinically plausible and relevant as tetraplegics tend to be hypo- to normotensive and more sedentary, resulting in lower HDL-C and a greater propensity toward impaired carbohydrate metabolism.

Autoimmune pancreatitis (AIP) has the potential to progress to a chronic state that forms pancreatic stones. The aim of this study was to clarify the risk factors underlying pancreatic stone formation in AIP. Sixty-nine patients with AIP who had been followed for at least 3 years were enrolled for evaluation of clinical and laboratory factors as well as computed tomography and endoscopic retrograde cholangiopancreatography findings. During the course of this study, increased or de novo stone formation was seen in 28 patients, who were defined as the stone-forming group. No stones were observed in 32 patients, who were defined as the non-stone-forming group. Nine patients who had stones at diagnosis but showed no change during the course of this study were excluded from our cohort. Univariate analysis revealed no significant differences in clinical or laboratory factors associated with AIP-specific inflammation between the two groups. However, pancreatic head swelling (P = 0.006) and narrowing of both Wirsung's and Santorini's ducts in the pancreatic head region (P = 0.010) were significantly more frequent in the stone-forming group. Furthermore, multivariate analysis identified Wirsung and Santorini duct narrowing at diagnosis as a significant independent risk factor for pancreatic stone formation (OR 4.4, P = 0.019). A primary risk factor for pancreatic stone formation in AIP was narrowing of both Wirsung's and Santorini's ducts, which most presumably led to pancreatic juice stasis and stone development.

Studies have been carried out at national and international levels to assess ethnic variations in the prevalence of cardiovascular diseases and their risk factors. However, ethnic variations in the contribution of various risk factors to complex diseases have been scarcely studied. Our study examined such variations in two ethnic groups in India, namely, Meiteis of Manipur (northeast India) and Aggarwals of Delhi (north India). Through random sampling, we selected 635 participants from the Meitei community and 181 Aggarwals from the Aggarwal Dharmarth Hospital, Delhi. Patients with coronary artery disease (CAD) and hypertension were identified based on their recent medical diagnostic history. Anthropometric parameters such as height, weight, waist and hip circumferences along with physiological parameters (blood pressures, both systolic and diastolic) and biochemical parameter (lipid profile) were measured for all study participants. Patient parameters were available from the medical reports recorded when patients were first diagnosed. Among CAD individuals, the Aggarwals showed higher mean values of weight, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), triglyceride (TC), low density lipoprotein (LDL), and very low density lipoprotein (VLDL) but had lower high density lipoprotein (HDL) levels than the Meiteis. The same trend for weight, BMI and lipid parameters could be seen among hypertensive individuals. In step-wise regression analysis, SBP, LDL and TG were found to significantly contribute to the risk for CAD in the Aggarwals; whereas in the Meiteis, SBP, VLDL, HDL, TC and LDL were found to significantly contribute to the risk for CAD. In hypertensive Aggarwal participants, SBP, DBP and waist-to-hip ratio were significant contributors for hypertension; whereas SBP, DBP, and height contributed significantly to risk for hypertension among the Meiteis. We found marked differences in conventional risk factors between the two ethnic groups. In India, as found elsewhere, the presence of substructuring of groups and hence, genetic isolation is high. More research is needed within this context to unveil the conventional risk factors for complex diseases.

The objectives of this study were to determine the risk factors for postpartum endometritis by evaluating several reproductive factors in individual cows, and to determine the effect of endometritis on the subsequent reproductive performance in dairy herds in Korea. The data, including health status, parity and body condition score (BCS) of cows, and calving date, were collected from 320 cows in eight dairy herds calving from January 2001 to October 2002. We used logistic regression to evaluate the effects of these factors on endometritis. A stepwise procedure, used to obtain the appropriate model with alpha=0.05, revealed that retained placenta, metabolic disorders and parity are the important risk factors for endometritis. The mean intervals from calving to first service and conception were prolonged (P<0.01) by 23 and 36 days, respectively, in the endometritis group compared to the non-endometritis group. The first service conception rate was lower (P<0.05) in the endometritis group (47.6%) than in the non-endometritis group (62.6%). The number of services per conception was higher (P<0.05) in the endometritis group (1.9) than in the non-endometritis group (1.6). We conclude that retained placenta, metabolic disorders and cow parity are strongly correlated with the development of postpartum endometritis, which decreases reproductive performance in dairy herds in Korea.

Abstract Blood lipids disorders are prevalent in the world. Some of their risk factors are modifiable such as mental and physical stress which existed in some places such as work environment. Objective of this study was to determine the effects of psychological and physical stress on the lipid profiles. It was a historical cohort study. The people who were employed as general worker were participated. The study was conducted with flexible interview for getting history, lipid profile examination, and a checklist including occupational and nonoccupational risk factors and using the health issues. According to the type of stress exposures, the study population was divided into 5 groups. Groups were followed for lipid profiles. These groups were exposed to psychological stress, physical stress or both of them; mild psychological stress (group 1), mild physical work without psychological stress (group 2), mild psychological stress and mild physical work (group 3), moderate physical work without psychological stress (group 4), and heavy physical work without psychological stress (group 5). Data were analyzed with SPSS 16. ANOVA, χ2, and exact test were calculated with considering P < .05 as significant level. Relative risks were calculated with confidence interval 95%. The means of lipid profiles were in normal ranges. The relative risks for triglycerides more than 200 mg/dL was 1.57 (1.02–2.42) and low density lipoprotein (LDL) more than 130 mg/dL was 14.54 (3.54–59.65) in group 1. The relative risks for high density lipoprotein (HDL) less than 45 mg/dL was 14.61 (8.31–25.68) in group 1 and 16.00 (8.30–30.83) in group 3. After multinomial logistic regression they had significant differences. Psychological stress was a risk factor for lipid disorders, and suitable physical activity was protective in this situation.

Interpersonal violence is a major contributor to the burden of disease globally, and in South Africa, it is the leading cause of injury. There is an emerging consensus that the development of actionable policy and effective prevention strategies for interpersonal violence requires an understanding of the contextual matters that elevate risk for interpersonal violence. The objective of this study was to explore community perceptions of risks for interpersonal violence in five townships in Cape Town, South Africa, with high rates of violence. Focus group discussions were conducted with community members to identify key factors in that contributed to being either a perpetrator or victim of interpersonal violence. The ecological framework was used to classify the risk factors as occurring at individual, relationship, community or society levels. Some of the risk factors identified included alcohol abuse, poverty, informality of settlements and cultural norms. Differences in how each of these risk factors are expressed and experienced in the five communities are also elucidated. This approach enabled the collection of contextual community-based data that can complement conventional surveillance data in the development of relevant community-level strategies for interpersonal violence prevention.

The health conditions encompass also the risk factors. The cognition and showing the range of social pedagogy students' interest in the knowledge and abilities useful for minimizing the causes and consequences of the health risk factors was the aim of the work. There were 154 social pedagogy students tested. The questionnaire was applicated within the confess of researches. The results, which were received, showed that the tested students are the most interested in knowledge and abilities within the confess of the factors like: alcoholism, drug addiction, poverty, unemployment, impracticality and different forms and kinds of violence in selected social groups. To the sources of the knowledge from which the students would like to use in the future were ranked post conference materials and the archival sources. The majority of students would like to participate in meetings with authority and work in support groups if we talk about the methods enabling them to gain the prophylactic abilities in the minimizing range of the risk factors.

To quantify the contribution of changes in different risk factors population levels and treatment uptake on the decline in CHD mortality in Denmark from 1991 to 2007 in different socioeconomic groups. We used IMPACTSEC, a previously validated policy model using data from different population registries. All adults aged 25-84 years living in Denmark in 1991 and 2007. Deaths prevented or postponed (DPP). There were approximately 11,000 fewer CHD deaths in Denmark in 2007 than would be expected if the 1991 mortality rates had persisted. Higher mortality rates were observed in the lowest socioeconomic quintile. The highest absolute reduction in CHD mortality was seen in this group but the highest relative reduction was in the most affluent socioeconomic quintile. Overall, the IMPACTSEC model explained nearly two thirds of the decline in. Improved treatments accounted for approximately 25% with the least relative mortality reduction in the most deprived quintile. Risk factor improvements accounted for approximately 40% of the mortality decrease with similar gains across all socio-economic groups. The 36% gap in explaining all DPPs may reflect inaccurate data or risk factors not quantified in the current model. According to the IMPACTSEC model, the largest contribution to the CHD mortality decline in Denmark from 1991 to 2007 was from improvements in risk factors, with similar gains across all socio-economic groups. However, we found a clear socioeconomic trend for the treatment contribution favouring the most affluent groups.

The Affordable Care Act provides for a program of risk adjustment in the individual and small group health insurance markets in 2014 as Marketplaces are implemented and new market reforms take effect. The purpose of risk adjustment is to lessen or eliminate the influence of risk selection on the premiums that plans charge. The risk adjustment methodology includes the risk adjustment model and the risk transfer formula. This article is the third of three in this issue of the Medicare & Medicaid Research Review that describe the ACA risk adjustment methodology and focuses on the risk transfer formula. In our first companion article, we discussed the key issues and choices in developing the methodology. In our second companion paper, we described the risk adjustment model that is used to calculate risk scores. In this article we present the risk transfer formula. We first describe how the plan risk score is combined with factors for the plan allowable premium rating, actuarial value, induced demand, geographic cost, and the statewide average premium in a formula that calculates transfers among plans. We then show how each plan factor is determined, as well as how the factors relate to each other in the risk transfer formula. The goal of risk transfers is to offset the effects of risk selection on plan costs while preserving premium differences due to factors such as actuarial value differences. Illustrative numerical simulations show the risk transfer formula operating as anticipated in hypothetical scenarios. PMID:25352994

To evaluate the effect of cola consumption on urinary stone risk factors in a controlled metabolic environment with a prospective cross-over study. Thirteen participants (10 normal and 3 calcium oxalate stone-formers) underwent 2 6-day phases on a controlled metabolic diet. During phase 1, subjects ingested 1 liter of cola daily, followed by a 3-week washout period. During phase 2, subjects ingested 1 liter of deionized water daily. Twenty-four-hour urine collections and serum metabolic panels were obtained for stone risk factors at the end of each phase. Urine and serum results of the cola phase were compared with those of the water phase. Normal subjects and stone-formers were combined for analysis after determining no significant difference between the 2 groups. No significant differences were found among cola and water treatment groups for normal subjects, stone-formers, or the pooled group. Cola exerts no detectable change in urinary risk factors associated with calcium oxalate stone formation. Cola consumption may not increase stone risk and may be an acceptable alternative source of daily fluid for patients unwilling to increase water consumption. Copyright © 2012 Elsevier Inc.

Cardiovascular diseases are among the most important sources of mortality and morbidity, and have a high disease burden. There are some major well-known risk factors, which contribute to the development of these diseases. Occupational stress is caused due to imbalance between job demands and individual's ability, and it has been implicated as an etiology for cardiovascular diseases. This study was conducted to evaluate the cardiovascular risk factors and different dimensions of occupational stress in high-ranking government officials, comparing an age and sex-matched group of office workers with them. We invited 90 high-ranking officials who managed the main governmental offices in a city, and 90 age and sex-matched office workers. The subjects were required to fill the occupational role questionnaire (Osipow) which evaluated their personal and medical history as well as occupational stress. Then, we performed physical examination and laboratory tests to check for cardiovascular risk factors. Finally, the frequency of cardiovascular risk factors and occupational stress of two groups were compared. High-ranking officials in our study had less work experience in their current jobs and smoked fewer pack-years of cigarette, but they had higher waist and hip circumference, higher triglyceride level, more stress from role overload and responsibility, and higher total stress score. Our group of office workers had more occupational stress because of role ambiguity and insufficiency, but their overall job stress was less than officials. The officials have higher scores in some dimensions of occupational stress and higher overall stress score. Some cardiovascular risk factors were also more frequent in managers.

Colorectal cancer (CRC) and atrial fibrillation/flutter (AF) share several risk factors including increasing age and obesity. However, the association between CRC and AF has not been thoroughly examined, especially in African Americans. In this study we aimed to assess the prevalence of AF and its risk factors in colorectal neoplasia in an African American. We reviewed records of 527 African American patients diagnosed with CRC and 1008 patients diagnosed with benign colonic lesions at Howard University Hospital from January 2000 to December 2012. A control group of 731 hospitalized patients without any cancer or colonic lesion were randomly selected from the same time and age range, excluding patients who had diagnosis of both CRC and/or adenoma. The presence or absence of AF was based upon ICD-9 code documentation. The prevalence of AF in these three groups was compared by multivariate logistic regression. The prevalence of AF was highest among CRC patients (10%) followed by adenoma patients (7.2%) then the control group (5.4%, P for trend = 0.002). In the three groups of participants, older age (P<0.008) and heart failure (P<0.001) were significantly associated with higher risk of AF. After adjusting for these risk factors, CRC (OR: 1.4(95%CI):0.9-2.2, P = 0.2) and adenoma (OR: 1.1(95%CI):0.7-1.6, P = 0.7) were not significantly associated AF compared to control group. AF is highly prevalent among CRC patients; 1 in 10 patients had AF in our study. The predictors of AF in CRC was similar to that in adenoma and other patients after adjustment for potential confounders suggesting that the increased AF risk in CRC is explained by higher prevalence of AF risk factors.

Background Epidemiologic data on the combined influence of several lifestyle factors on diabetes risk are rare, particularly among older adults. Objective Examine how combinations of lifestyle risk factors relate to the 11-year risk of incident diabetes. Design Population-based prospective cohort study. Setting National Institutes of Health (NIH)-AARP Diet and Health Study. Participants 114996 men and 92483 women aged 50–71 in 1995–1996 without evidence of heart disease, cancer, or diabetes. Measurements A comprehensive survey of demographic characteristics and lifestyle factors, including dietary intake, body weight and height, physical activity, smoking, and alcohol at baseline (1995–1996). Low-risk groups were formed by dichotomizing each lifestyle factor. Incident self-reported physician-diagnosed diabetes was identified with a follow-up survey in 2004–2006. Results There were 11031 (9.6%) men and 6969 (7.5%) women who developed new-onset diabetes. The odds for diabetes were 31% (odds ratio (OR): 0.69; 95% confidence interval (CI): 0.68, 0.71) lower for each 1 additional lifestyle factor in the low-risk group among men and 39% (OR: 0.61; 95% CI: 0.60, 0.63) lower among women. Men and women with a diet score, physical activity level, smoking status, and alcohol use all in the low-risk group had ORs for diabetes of 0.61 (95% CI: 0.56, 0.66) and 0.43 (95% CI: 0.34, 0.55), respectively. When absence of overweight or obesity was added, ORs for diabetes were 0.28 (95% CI: 0.23, 0.34) and 0.16 (95% CI: 0.10, 0.24) for men and women, respectively. Results did not differ by family history of diabetes and level of adiposity. Limitation The study was observational with potential for residual confounding. Conclusions Lifestyle factors, when considered in combination, are associated with a substantial reduction in risk for diabetes. PMID:21893622

Purpose Adolescents (age 15 to 21 years) compared with younger children with mature B-cell non-Hodgkin's lymphoma (NHL) have been historically considered to have an inferior prognosis. We therefore analyzed the impact of age and other diagnostic factors on the risk of treatment failure in children and adolescents treated on the French-American-British Mature B-Cell Lymphoma 96 (FAB LMB 96) trial. Patients and Methods Patients were divided by risk: group A (limited), group B (intermediate), and group C (advanced), as previously described. Prognostic factors analyzed for event-free survival (EFS) included age (< 15 v ≥ 15 years), stage (I/II v III/IV), primary site, lactate dehydrogenase (LDH), bone marrow/CNS (BM/CNS) involvement, and histology (diffuse large B-cell lymphoma v mediastinal B-cell lymphoma v Burkitt lymphoma or Burkitt-like lymphoma). Results The 3-year EFS for the whole cohort was 88% ± 1%. Age was not associated as a risk factor for increased treatment failure in either univariate analysis (P = .15) or multivariate analysis (P = .58). Increased LDH (≥ 2 × upper limit of normal [ULN] v < 2 × ULN), primary site, and BM-positive/CNS-positive disease were all independent risk factors associated with a significant increase in treatment failure rate (relative risk, 2.0; P < .001, P < .012, and P < .001, respectively). Conclusion LDH level at diagnosis, mediastinal disease, and combined BM-positive/CNS-positive involvement are independent risk factors in children with mature B-cell NHL. Future studies should be developed to identify specific therapeutic strategies (immunotherapy) to overcome these risk factors and to identify the biologic basis associated with these prognostic factors in children with mature B-cell NHL.

Background Most European countries are ethnically and culturally diverse. Globally, cardiovascular disease (CVD) is the leading cause of death. The major risk factors for CVD have been well established. This picture holds true for all regions of the world and in different ethnic groups. However, the prevalence of CVD and related risk factors vary among ethnic groups. Methods This article provides a review of current understanding of the epidemiology of vascular disease, principally coronary heart disease (CHD), stroke and related risk factors among populations of Sub-Sahara African descent (henceforth, African descent) in comparison with the European populations in Europe. Results Compared with European populations, populations of African descent have an increased risk of stroke, whereas CHD is less common. They also have higher rates of hypertension and diabetes than European populations. Obesity is highly prevalent, but smoking rate is lower among African descent women. Older people of African descent have more favourable lipid profile and dietary habits than their European counterparts. Alcohol consumption is less common among populations of African descent. The rate of physical activity differs between European countries. Dutch African-Suriname men and women are less physically active than the White-Dutch whereas British African women are more physically active than women in the general population. Literature on psychosocial stress shows inconsistent results. Conclusion Hypertension and diabetes are highly prevalent among African populations, which may explain their high rate of stroke in Europe. The relatively low rate of CHD may be explained by the low rates of other risk factors including a more favourable lipid profile and the low prevalence of smoking. The risk factors are changing, and on the whole, getting worse especially among African women. Cohort studies and clinical trials are therefore needed among these groups to determine the relative contribution of vascular risk factors, and to help guide the prevention efforts. There is a clear need for intervention studies among these populations in Europe. PMID:19671137

Little is known about the needs of substance-using juveniles in treatment aimed at reducing criminal recidivism. Therefore, we aimed to examine treatment needs of substance-using juvenile offenders. Differences were examined between juvenile offenders who abstain from substance use (ASU; n=1974) and substance-using juvenile offenders without (SU; n=7000) and with substance use problems (SUP; n=3317), in the prevalence of risk/protective factors for criminal recidivism and strength of associations between risk/protective factors and criminal recidivism. We conducted secondary data analysis on recidivism risk assessments, collected with the Washington State Juvenile Court Assessment, and re-offending data. Analyses of variance and Partial correlations, adjusted for age, gender and ethnicity were applied, as well as Fisher's z tests and logistic regression analyses. Results showed that substance-using offenders, especially those with substance use problems, had more risk factors and less protective factors than ASU youths in the domains of school, use of free time, relationships, family, attitude, aggression and skills. The associations between most of the risk/protective factors and recidivism were stronger in the ASU group than in the SUP group. Substance use uniquely predicted recidivism, net of risk factors. These results suggest that general interventions for juvenile offenders addressing risk and protective factors with the aim to reduce recidivism may be less effective for offenders with substance use problems, and that substance use (problems) should be addressed, too.

Predictors of medication nonadherence differ among black and white patients with heart failure.

PubMed

Dickson, Victoria Vaughan; Knafl, George J; Riegel, Barbara

2015-08-01

Heart failure (HF) is a global public health problem, and outcomes remain poor, especially among ethnic minority populations. Medication adherence can improve heart failure outcomes but is notoriously low. The purpose of this secondary analysis of data from a prospective cohort comparison study of adults with heart failure was to explore differences in predictors of medication nonadherence by racial group (Black vs. White) in 212 adults with heart failure. Adaptive modeling analytic methods were used to model HF patient medication nonadherence separately for Black (31.7%) and White (68.3%) participants in order to investigate differences between these two racial groups. Of the 63 Black participants, 33.3% had low medication adherence, compared to 27.5% of the 149 White participants. Among Blacks, 16 risk factors were related to adherence in bivariate analyses; four of these (more comorbidities, lower serum sodium, higher systolic blood pressure, and use of fewer activities compensating for forgetfulness) jointly predicted nonadherence. In the multiple risk factor model, the number of risk factors in Black patients ranged from 0 to 4, and 76.2% had at least one risk factor. The estimated odds ratio for medication nonadherence was increased 9.34 times with each additional risk factor. Among White participants, five risk factors were related to adherence in bivariate analyses; one of these (older age) explained the individual effects of the other four. Because Blacks with HF have different and more risk factors than Whites for low medication adherence, interventions are needed that address unique risk factors among Black patients with HF. © 2015 Wiley Periodicals, Inc.

A 12-week multidomain intervention versus active control to reduce risk of Alzheimer’s disease: study protocol for a randomized controlled trial

PubMed Central

2013-01-01

Background Disappointing results from clinical trials of disease-modifying interventions for Alzheimer’s dementia (AD), along with reliable identification of modifiable risk factors in mid life from epidemiological studies, have contributed to calls to invest in risk-reduction interventions. It is also well known that AD-related pathological processes begin more than a decade before the development of clinical signs. These observations suggest that lifestyle interventions might be most effective when targeting non-symptomatic adults at risk of AD. To date, however, the few dementia risk-reduction programs available have targeted individual risk factors and/or were restricted to clinical settings. The current study describes the development of an evidence-based, theoretically-driven multidomain intervention to reduce AD risk in adults at risk. Method The design of Body Brain Life (BBL) is a randomized controlled trial (RCT) to evaluate a 12-week online AD risk-reduction intervention. Eligible participants with several modifiable risk factors on the Australian National University (ANU) AD Risk Index (ANU-ADRI) are randomly allocated to an online only group, an online and face-to-face group, or an active control group. We aim to recruit 180 participants, to undergo a comprehensive cognitive and physical assessment at baseline, post-intervention, and 6-month follow-up assessment. The intervention comprises seven online modules (dementia literacy, risk factor education, engagement in physical, social, and cognitive lifestyles, nutrition, and health monitoring) designed using contemporary models of health behavior change. Discussion The BBL program is a novel online intervention to reduce the risk of AD in middle-aged adults at risk. The trial is currently under way. It is hypothesized that participants in the intervention arms will make lifestyle changes in several domains, and that this will lead to a reduction in their AD risk profile. We also expect to show that health behavior change is underpinned by changes in psychological determinants of behavior. If successful, the findings will contribute to the development of further dementia risk reduction interventions, and thus contribute to the urgent need to lower dementia risk factors in the population to alter future projections of disease prevalence. Longer follow-up of BBL participants and replications using large samples are required to examine whether reduction in AD risk factors will be associated with reduced prevalence.

Background The Management of Myelomeningocele Study (MOMS) was a multi-center randomized trial to compare prenatal and standard postnatal closure of myelomeningocele. The trial was stopped early at recommendation of the Data and Safety Monitoring Committee and outcome data for 158 of the 183 randomized women published. Objective In this report, pregnancy outcomes for the complete trial cohort are presented. We also sought to analyze risk factors for adverse pregnancy outcome among those women who underwent prenatal myelomeningocele repair. Study Design Pregnancy outcomes were compared between the two surgery groups. For women who underwent prenatal surgery antecedent demographic, surgical and pregnancy complication risk factors were evaluated for the following outcomes: premature spontaneous membrane rupture on or before 34 weeks 0 days (PPROM), spontaneous membrane rupture at any gestational age (SROM), preterm delivery at 34 weeks 0 days or earlier (PTD) and non-intact hysterotomy (minimal uterine wall tissue between fetal membranes and uterine serosa, or partial or complete dehiscence at delivery) and chorioamniotic membrane separation. Risk factors were evaluated using chi-square and Wilcoxon tests and multivariable logistic regression. Results A total of 183 women were randomized: 91 to prenatal surgery and 92 to postnatal surgery groups. Analysis of the complete cohort confirmed initial findings: that prenatal surgery was associated with an increased risk for membrane separation, oligohydramnios, spontaneous membrane rupture, spontaneous onset of labor and earlier gestational age at birth. In multivariable logistic regression of the prenatal surgery group adjusting for clinical center, earlier gestational age at surgery and chorioamniotic membrane separation were associated with increased risk of SROM (odds ratio [OR] 1.49, 95% confidence interval [CI] 1.01-2.22; OR 2.96, 95% CI 1.05-8.35, respectively). Oligohydramnios was associated with an increased risk of subsequent PTD (OR 9.21, 95% CI 2.19 - 38.78). Nulliparity was a risk factor for non-intact hysterotomy (OR 3.68, 95% CI 1.35 – 10.05). Conclusions Despite the confirmed benefits of prenatal surgery, considerable maternal and fetal risk exists compared with postnatal repair. Early gestational age at surgery and development of chorioamniotic membrane separation are risk factors for ruptured membranes. Oligohydramnios is a risk factor for preterm delivery and nulliparity is a risk factor for non-intact hysterotomy at delivery. PMID:27496687

Background Given the increasing worldwide incidence of diabetes, methods to assess diabetes risk which would identify those at highest risk are needed. We compared two risk-stratification approaches for incident type 2 diabetes mellitus (T2DM); factors of metabolic syndrome (MetS) and a previously developed diabetes risk score, PreDx® Diabetes Risk Score (DRS). DRS assesses 5 yr risk of incident T2DM based on the measurement of 7 biomarkers in fasting blood. Methodology/Principal Findings DRS was evaluated in baseline serum samples from 4,128 non-diabetic subjects in the Inter99 cohort (Danes aged 30–60) for whom diabetes outcomes at 5 years were known. Subjects were classified as having MetS based on the presence of at least 3 MetS risk factors in baseline clinical data. The sensitivity and false positive rate for predicting diabetes using MetS was compared to DRS. When the sensitivity was fixed to match MetS, DRS had a significantly lower false positive rate. Similarly, when the false positive rate was fixed to match MetS, DRS had a significantly higher specificity. In further analyses, subjects were classified by presence of 0–2, 3 or 4–5 risk factors with matching proportions of subjects distributed among three DRS groups. Comparison between the two risk stratification schemes, MetS risk factors and DRS, were evaluated using Net Reclassification Improvement (NRI). Comparing risk stratification by DRS to MetS factors in the total population, the NRI was 0.146 (p = 0.008) demonstrating DRS provides significantly improved stratification. Additionally, the relative risk of T2DM differed by 15 fold between the low and high DRS risk groups, but only 8-fold between the low and high risk MetS groups. Conclusions/Significance DRS provides a more accurate assessment of risk for diabetes than MetS. This improved performance may allow clinicians to focus preventive strategies on those most in need of urgent intervention. PMID:21829540

Urbanization can be detrimental to health in populations due to changes in dietary and physical activity patterns. The aim of this study was to determine the effect of migration on the incidence of hypertension. Participants of the PERU MIGRANT study, that is, rural, urban and rural-to-urban migrants, were re-evaluated after 5 years after baseline assessment. The outcome was incidence of hypertension; and the exposures were study group and other well-known risk factors. Incidence rates, relative risks (RRs) and population attributable fractions (PAFs) were calculated. At baseline, 201 (20.4%), 589 (59.5%) and 199 (20.1%) participants were rural, rural-to-urban migrant and urban subjects, respectively. Overall mean age was 47.9 (s.d.±12.0) years, and 522 (52.9%) were female. Hypertension prevalence at baseline was 16.0% (95% confidence interval (CI) 13.7–18.3), being more common in urban group; whereas pre-hypertension was more prevalent in rural participants (P<0.001). Follow-up rate at 5 years was 94%, 895 participants were re-assessed and 33 (3.3%) deaths were recorded. Overall incidence of hypertension was 1.73 (95%CI 1.36–2.20) per 100 person-years. In multivariable model and compared with the urban group, rural group had a greater risk of developing hypertension (RR 3.58; 95%CI 1.42–9.06). PAFs showed high waist circumference as the leading risk factor for the hypertension development in rural (19.1%), migrant (27.9%) and urban (45.8%) participants. Subjects from rural areas are at higher risk of developing hypertension relative to rural–urban migrant or urban groups. Central obesity was the leading risk factor for hypertension incidence in the three population groups. PMID:26865219

Little is known of the risk factor disparities in first stroke among Jewish and Arab patients undergoing rehabilitation in Israel. To investigate the age, gender and risk factor disparities in first stroke among Jewish (immigrant and non-immigrant) and Arab patients undergoing rehabilitation and to compare the prevalence and odds ratio of stroke risk factors in these patients. The database of the Department of Neurological Rehabilitation C at Loewenstein Rehabilitation Center was used to investigate first ischemic and hemorrhagic stroke patients admitted for hospital rehabilitation over a 15 year period, January 1993 to December 2008. Particular attention was paid to age, gender and risk factor disparities. The 2000 patients with first stroke who were included in the study were grouped as Jewish (immigrant and non-immigrant) orArab; there were 237 Arabs, 370 non-immigrant Jews and 1393 immigrant Jews. A high percentage of Arab patients were found to have hypertension and diabetes mellitus, while a high percentage of Jewish immigrants had stenosis of the internal carotid artery. The study demonstrated some differences in the effect of risk factors between the groups. It may be important to address such differences when developing stroke preventative strategies in this population of Jewish and Arab stroke survivors in Israel.

Though still high, the infant mortality rate in Guinea-Bissau has declined. We aimed to identify risk factors including vaccination coverage, for infant mortality in the rural population of Guinea-Bissau and assess whether these risk factors changed from 1992-3 to 2002-3. The Bandim Health Project (BHP) continuously surveys children in rural Guinea-Bissau. We investigated the association between maternal and infant factors (especially DTP and measles coverage) and infant mortality. Hazard ratios (HR) were calculated using Cox regression. We tested for interactions with sex, age groups (defined by current vaccination schedule) and cohort to assess whether the risk factors were the same for boys and girls, in different age groups in 1992-3 and in 2002-3. The infant mortality rate declined from 148/1000 person years (PYRS) in 1992-3 to 124/1000 PYRS in 2002-3 (HR = 0.88;95%CI:0.77-0.99); this decline was significant for girls (0.77;0.64-0.94) but not for boys (0.97;0.82-1.15) (p = 0.10 for interaction). Risk factors did not differ significantly by cohort in either distribution or effect. Mortality decline was most marked among girls aged 9-11 months (0.56;0.37-0.83). There was no significant mortality decline for girls 1.5-8 months of age (0.93;0.68-1.28) (p = 0.05 for interaction). DTP and measles coverage increased from 1992-3 to 2002-3. Risk factors did not change with the decline in mortality. Due to beneficial non-specific effects for girls, the increased coverage of measles vaccination may have contributed to the disproportional decline in mortality by sex and age group.

Context: Specific movement patterns have been identified as possible risk factors for noncontact lower extremity injuries. The Dynamic Integrated Movement Enhancement (DIME) was developed to modify these movement patterns to decrease injury risk. Objective: To determine if the DIME is effective for preventing lower extremity injuries in US Military Academy (USMA) cadets. Design: Cluster-randomized controlled trial. Setting: Cadet Basic Training at USMA. Patients or Other Participants: Participants were 1313 cadets (1070 men, 243 women). Intervention(s): Participants were cluster randomized to 3 groups. The active warm-up (AWU) group performed standard Army warm-up exercises. The DIME groups were assigned to a DIME cadre-supervised (DCS) group or a DIME expert-supervised (DES) group; the former consisted of cadet supervision and the latter combined cadet and health professional supervision. Groups performed exercises 3 times weekly for 6 weeks. Main Outcome Measure(s): Cumulative risk of lower extremity injury was the primary outcome. We gathered data during Cadet Basic Training and for 9 months during the subsequent academic year. Risk ratios and 95% confidence intervals (CIs) were calculated to compare groups. Results: No differences were seen between the AWU and the combined DIME (DCS and DES) groups during Cadet Basic Training or the academic year. During the academic year, lower extremity injury risk in the DES group decreased 41% (relative risk [RR] = 0.59; 95% CI = 0.38, 0.93; P = .02) compared with the DCS group; a nonsignificant 25% (RR = 0.75; 95% CI = 0.49, 1.14; P = .18) decrease occurred in the DES group compared with the AWU group. Finally, there was a nonsignificant 27% (RR = 1.27; 95% CI = 0.90, 1.78; P = .17) increase in injury risk during the academic year in the DCS group compared with the AWU group. Conclusions: We observed no differences in lower extremity injury risk between the AWU and combined DIME groups. However, the magnitude and direction of the risk ratios in the DES group compared with the AWU group, although not statistically significant, indicate that professional supervision may be a factor in the success of injury-prevention programs.

Binge drinking is common among young people but often relevant risk factors are not recognized. eHealth apps, attractive for young people, may be useful to enhance awareness of this problem. We aimed at developing a current risk estimation model for binge drinking, incorporated into an eHealth app--D-ARIANNA (Digital-Alcohol RIsk Alertness Notifying Network for Adolescents and young adults)--for young people. A longitudinal approach with phase 1 (risk estimation), phase 2 (design), and phase 3 (feasibility) was followed. Risk/protective factors identified from the literature were used to develop a current risk estimation model for binge drinking. Relevant odds ratios were subsequently pooled through meta-analytic techniques with a random-effects model, deriving weighted estimates to be introduced in a final model. A set of questions, matching identified risk factors, were nested in a questionnaire and assessed for wording, content, and acceptability in focus groups involving 110 adolescents and young adults. Ten risk factors (5 modifiable) and 2 protective factors showed significant associations with binge drinking and were included in the model. Their weighted coefficients ranged between -0.71 (school proficiency) and 1.90 (cannabis use). The model, nested in an eHealth app questionnaire, provides in percent an overall current risk score, accompanied by appropriate images. Factors that mostly contribute are shown in summary messages. Minor changes have been realized after focus groups review. Most of the subjects (74%) regarded the eHealth app as helpful to assess binge drinking risk. We could produce an evidence-based eHealth app for young people, evaluating current risk for binge drinking. Its effectiveness will be tested in a large trial.

Differences in problem gambling rates between males and females suggest that associated risk factors vary by gender. Previous combined analyses of male and female gambling may have obscured these distinctions. This study aimed to develop separate risk factor models for gambling problems for males and for females, and identify gender-based similarities and differences. It analysed data from the largest prevalence study in Victoria Australia (N = 15,000). Analyses determined factors differentiating non-problem from at-risk gamblers separately for women and men, then compared genders using interaction terms. Separate multivariate analyses determined significant results when controlling for all others. Variables included demographics, gambling behaviour, gambling motivations, money management, and mental and physical health. Significant predictors of at-risk status amongst female gamblers included: 18-24 years old, not speaking English at home, living in a group household, unemployed or not in the workforce, gambling on private betting, electronic gaming machines (EGMs), scratch tickets or bingo, and gambling for reasons other than social reasons, to win money or for general entertainment. For males, risk factors included: 18-24 years old, not speaking English at home, low education, living in a group household, unemployed or not in the workforce, gambling on EGMs, table games, races, sports or lotteries, and gambling for reasons other than social reasons, to win money or for general entertainment. High risk groups requiring appropriate interventions comprise young adults, especially males; middle-aged female EGM gamblers; non-English speaking populations; frequent EGM, table games, race and sports gamblers; and gamblers motivated by escape.

Children with visual impairments are very heterogeneous in terms of the extent of visual and developmental etiology. The aim of the present study was to investigate a possible correlation between prevalence of clinical risk factors of visual processing impairments and characteristics of viewing behavior. We tested 149 children with visual information processing impairments (90 boys, 59 girls; mean age (SD)=7.3 (3.3)) and 127 children without visual impairments (63 boys and 64 girls, mean age (SD)=7.9 (2.8)). Visual processing impairments were classified based on the time it took to complete orienting responses to various visual stimuli (form, contrast, motion detection, motion coherence, color and a cartoon). Within the risk group, children were divided into a fast, medium or slow group based on the response times to a highly salient stimulus. The relationship between group specific response times and clinical risk factors was assessed. The fast responding children in the risk group were significantly slower than children in the control group. Within the risk group, the prevalence of cerebral visual impairment, brain damage and intellectual disabilities was significantly higher in slow responding children compared to faster responding children. The presence of nystagmus, perceptual dysfunctions, mean visual acuity and mean age did not significantly differ between the subgroups. Orienting responses are related to risk factors for visual processing impairments known to be prevalent in visual rehabilitation practice. The proposed method may contribute to assessing the effectiveness of visual information processing in children. Copyright © 2014 Elsevier Ltd. All rights reserved.

Background: Coronary Artery Disease is known as the main cause of death in industrialized countries. Relation between this disease and some infections such as Helicobacter pylori (H.pylori) has been shown in several studies. The purpose of this study was to dermine the relationship between Hypylori and mycardical infarctions. Methods: Seventy-three myocardial infarction patients and 78 individuals with no history of this disease were compared. Patients and control matched for age and sex person to person by the match method. Levels of serum IgA and IgG antibodies against H. pylori were measured by Elisa method. Also, cholesterol, triglyceride, LDL, HDL measured in both groups and data were compared between two groups in terms of relation with cardiac risk factors. Results: From 151 participants, 73 were patients and 78 were control subjects. The percentage of IgG positive cases against H. pylori was 57.5% in the case group and 32.1% in the control group (p=0.002, OR: 2.87 CI: 95%; 1.5-5.6). Meanwhile, there was no significant difference in IgA positive cases between the two groups (42.5% and 48.7% in the case and control groups, respectively) (p=0.44; OR: 0.78 95% CI; 0.41-1.48). The study showed 74.2% of cases in the case group and 45.2% in the control group were positive for both IgG and IgA (p=0.01; OR: 3.5 95% CI; 1.3-9.5). No significant differences were found between two groups in terms of relation between H. pylori related antibodies level and heart disease classic risk factors (smoking, hypertension,…), sex, and age, but between dyslipidemia and H. pylori related antibodies was significant differences in case group (p=0.05). Conclusion: According to the results, it seems there is a relation between H. pylori infection and myocardial infarction. Also, between dislipidemia and H. Pylori antibodies in case group were significant difference. Therefore, H. pylori can be a new risk factor for atherosclerosis or can be exacerbate effect of other risk factors. Proper diagnosis and treatment of these infections can be useful in prone patients. More studies with larger sample groups are needed to review the possible role of this pathogen as a heart disease risk factor. PMID:24024020

To study the risk factors for elevated serum total bile acid (TBA) in preterm infants. A retrospective analysis was performed for the clinical data of 216 preterm infants who were admitted to the neonatal intensive care unit. According to the presence or absence of elevated TBA (TBA >24.8 μmol/L), the preterm infants were divided into elevated TBA group with 53 infants and non-elevated TBA group with 163 infants. A univariate analysis and an unconditional multivariate logistic regression analysis were used to investigate the risk factors for elevated TBA. The univariate analysis showed that there were significant differences between the elevated TBA group and the non-elevated TBA group in gestational age at birth, birth weight, proportion of small-for-gestational-age infants, proportion of infants undergoing ventilator-assisted ventilation, fasting time, parenteral nutrition time, and incidence of neonatal respiratory failure and sepsis (P<0.05). The unconditional multivariate logistic regression analysis showed that low birth weight (OR=3.84, 95%CI: 1.53-9.64) and neonatal sepsis (OR=2.56, 95%CI: 1.01-6.47) were independent risk factors for elevated TBA in preterm infants. Low birth weight and neonatal sepsis may lead to elevated TBA in preterm infants.

To evaluate the risk factors for gestational diabetes mellitus (GDM) and gestational impaired glucose tolerance (GIGT). A prospective case-control study was performed in 85 women with GDM, 63 cases with GIGT and 125 cases as control recruited from Feb 2004 to Aug 2004 in Peking University First Hospital. Univariate analysis and multivariate logistic regression were used to identify risk factors of GDM and GIGT. (1) The mean age, and body mass index (BMI) before pregnancy and larger maternal weight gains during pregnancy were significantly different between GDM/GIGT and control group (P < 0.05). (2) More intakes of fruits and carbohydrate per day increased the incidence of GDM and GIGT (P < 0.05). (3) There was a higher proportion of women with family history of diabetes among the GDM (42.2%) and GIGT (36.5%) compared with control group (19.2%). Irregular menses (16.5%, 23.8%), and polycystic ovary syndrome (PCOS) (5.9%, 3.2%) were more prevalent in the GDM, GIGT groups versus control subjects (6.4%, 0). The incidence of vulvovaginal candidiasis (VVC) was significantly higher in pregnant women with GDM and GIGT (15.3% and 17.4%) than in control group (7.2%). (4) Multivariate logistic regression showed that age, irregular menses, BMI before pregnancy, history of spontaneous abortion, educational level and VVC all were independent factors for GDM or GIGT. Maternal age, irregular menses, obesity before gestation, rapid weight gains during pregnancy, history of spontaneous abortion as well as VVC are independent risk factors for GDM or GIGT. PCOS and family history of diabetes increase the incidence of GDM and GIGT but these are not independent risk factors for GDM and GIGT.

Cardiovascular diseases are the leading cause of death in the majority of developed and developing countries. African countries are currently facing an increase in both cardiovascular and transmitted diseases. In addition, cardiovascular risk varies among different socioeconomic groups. Thus, we determined the prevalence of modifiable cardiovascular risk factors in apparently healthy public-sector workers and investigated possible relationships with socioeconomic status. We employed a cross-sectional study comprising 42.2% (n = 615) of the public-sector workers at Agostinho Neto University, 48% (n = 294) male and 52% (n= 321) female, with ages between 20 and 72 years and from various socioeconomic groups. The study was conducted from February 2009 to December 2010. Personal, anthropometric, biochemical, hemodynamic, socioeconomic, and physical activity data were collected. The prevalence rates of cardiovascular risk factors were as follows: hypertension, 45.2% (men 46.3%, women 44.2%, P > 0.05); hypercholesterolemia, 11.1% (men 10.5%, women 11.5%, P > 0.05); low high-density lipoprotein (HDL) cholesterol, 50.1% (men 36.9%, women 62.3%; P < 0.05); hypertriglyceridemia, 10.6% (men 12.6%, women 8.7%, P > 0.05); smoking, 7.2% (men 10.2%, women 4.4%; P < 0.05); diabetes, 5.7% (men 5.5%, women 5.9%, P > 0.05); overweight, 29.3% (men 27.3%, women 31.2%, P > 0.05); obesity, 19.6% (men 9.2%, women 29.0%; P < 0.05); sedentary lifestyle, 87.2% (men 83.0%, women 91,0%, P < 0.05); and left ventricular hypertrophy, 20% (men 32.0%, women 9.0%; P < 0.05). At least one risk factor was present in 27.7% of the sample; 15.2% had two risk factors, and 31.4% had three or more risk factors. Among the individuals with low socioeconomic status, 41.0% had three or more risk factors. The results of this study suggest the existence of a high prevalence of multiple risk factors for cardiovascular disease in apparently healthy public-sector workers in Angola. The workers in lower socioeconomic groups had higher incidences of hypertension, smoking, and left ventricular hypertrophy.

As drug costs rose in the 1990s, health maintenance organizations (HMOs) began transferring risk for prescription drug expenditures to physician groups. With principal-agent theory as a framework for understanding drug-risk transfer, we used a multiple case-study design to examine the relationship between the level of drug risk that a physician group accepts and the physician group's adoption of drug-use management strategies. The data demonstrated that adoption of drug-use management innovations was not related to level of risk for pharmacy costs and that factors other than drug-risk level (e.g., contracting and data issues, financial and market factors, and physician group assessments of the fairness and incentives of risk contracts) can influence the principal-agent relationship. The data also revealed a novel form of information asymmetry between physicians and HMOs and unexpected failures of HMOs to fully enable their physician-agents. We believe these observations reflect the complexity of relationships in the health care system and have implications for the use of incentives. Based on principal-agent theory and our findings, we offer an alternative approach to drug-risk contracting that reduces physicians responsibility for aspects of drug use that are beyond their control while maintaining the incentives to manage drug costs and use that were the original intent of drug-risk contracting.

Headache is a common health problem in adolescents. There are a number of risk factors for headache in adolescents that are amenable to intervention. The aim of the study was to assess the effectiveness of a low-level headache prevention programme in the classroom setting to prevent these risk factors. In all, 1674 students in 8th-10th grade at 12 grammar schools in greater Munich, Germany, were cluster randomized into intervention and control groups. A standardized 60-min prevention lesson focusing on preventable risk factors for headache (physical inactivity, coffee consumption, alcohol consumption and smoking) and providing instructions on stress management and neck and shoulder muscle relaxation exercises was given in a classroom setting. Seven months later, students were reassessed. The main outcome parameter was headache cessation. Logistic regression models with random effects for cluster and adjustment for baseline risk factors were calculated. Nine hundred students (intervention group N = 450, control group N = 450) with headache at baseline and complete data for headache and confounders were included in the analysis. Headache cessation was observed in 9.78% of the control group compared with 16.22% in the intervention group (number needed to treat = 16). Accounting for cluster effects and confounders, the probability of headache cessation in the intervention group was 1.77 (95% confidence interval = [1.08; 2.90]) higher than in the control group. The effect was most pronounced in adolescents with tension-type headache: odds ratio = 2.11 (95% confidence interval = [1.15; 3.80]). Our study demonstrates the effectiveness of a one-time, classroom-based headache prevention programme. © 2014 EAN.

To quantify the variation in rates of absence due to musculoskeletal pain across 47 occupational groups (mostly nurses and office workers) from 18 countries, and to explore personal and group-level risk factors that might explain observed differences. A standardised questionnaire was used to obtain information about musculoskeletal pain, sickness absence and possible risk factors in a cross-sectional survey of 12 416 workers (92-1017 per occupational group). Additionally, group-level data on socioeconomic variables, such as sick pay and unemployment rates, were assembled by members of the study team in each country. Associations of sickness absence with risk factors were examined by Poisson regression. Overall, there were more than 30-fold differences between occupational groups in the 12-month prevalence of prolonged musculoskeletal sickness absence, and even among office workers carrying out similar occupational tasks, the variation was more than tenfold. Personal risk factors included older age, lower educational level, tendency to somatise, physical loading at work and prolonged absence for non-musculoskeletal illness. However, these explained little of the variation between occupational groups. After adjustment for individual characteristics, prolonged musculoskeletal sickness absence was more frequent in groups with greater time pressure at work, lower job control and more adverse beliefs about the work-relatedness of musculoskeletal disorders. Musculoskeletal sickness absence might be reduced by eliminating excessive time pressures in work, maximising employees' responsibility and control and providing flexibility of duties for those with disabling symptoms. Care should be taken not to overstate work as a cause of musculoskeletal injury.

Helicobacter pylori is now incriminated in the pathogenesis of atherosclerosis. To examine the importance of H. pylori infection as a cardiovascular disease (CVD) risk factor. Two hundred five patients (128 with H. pylori infection [HP-seropositive] and 77 without) had a baseline assessment for other potential CVD risk factors and were followed prospectively for 10 years (1999-2008). They were assessed on a monthly basis for the outcomes of carotid plaque, angina pectoris, myocardial infarction, and stroke. In the HP-seropositive group, male sex and quartile 4 for IgG anti-H. pylori antibodies (anti-HP Ab) were correlated with traditional CVD risk factors, stroke, myocardial infarction, and angina pectoris. At the baseline assessment, the levels of carotid intima-media thickness, blood fibrinogen, total cholesterol, fasting plasma glucose, and uric acid were higher in H. pylori-infected patients than in the uninfected group. Serum HDL-cholesterol was significantly lower in the HP-seropositive group. Men had higher levels of IgG anti-HP Ab, waist circumference, blood pressure, uric acid, and total cholesterol than women. Within the HP-seropositive group, individuals in quartile 4 for IgG anti-HP Ab had higher rates of elevated fibrinogen, diabetes mellitus, low high-density lipoprotein cholesterol, arterial hypertension, and high total cholesterol than those in quartile 1. After adjusting for traditional CVD risk factors, H. pylori infection was the only independent predictor of incident carotid plaque (multivariate odds ratio [OR] = 2.3, 95% confidence interval [CI]: 1.2-7.2; P < 0.0001) and incident acute stroke (multivariate OR = 3.6, 95% CI: 1.4-8.2; P < 0.0001). Within the HP-seropositive group and after adjusting for traditional CVD risk factors, male sex was the only independent predictor of incident angina pectoris (multivariate OR = 3.5, 95% CI: 1.6-16; P < 0.0001), incident acute stroke (multivariate OR = 3.2, 95% CI: 1.4-28; P < 0.0001), and acute myocardial infarction (multivariate OR = 7.2, 95% CI: 3.1-18; P < 0.0001). Our study provides evidence for an association among known CVD risk factors, carotid plaque, stroke, and H. pylori infection. Among infected individuals, there is a significant association among severity of HP-seropositivity, male sex, and CVD. The eradication of H. pylori infection may therefore reduce the emerging burden of CVD in Africa.

The current investigation aimed to assess levels of knowledge about risk factors for heart disease among midlife Israeli women, and to evaluate the relationship of knowledge to personal risk factors and vulnerability to heart disease. Face-to-face interviews with women aged 45-64 years were conducted during 2004-2006 within three population groups: long-term Jewish residents (LTR), immigrants from the former Soviet Union, and Arab women. The survey instrument included six knowledge statements relating to: the risk after menopause, family history, elevated cholesterol level, diabetes, obesity, and warning signs of a heart attack. The findings showed wide disparities in knowledge by educational level and between immigrants and LTR, after taking into account personal risk factors and education. Personal risk factors were not significantly related to the knowledge items, except for personal history of cardiovascular disease, which was associated with knowledge about "warning signs of a heart attack" and "family history." Women who perceived themselves as more vulnerable to heart disease were more likely to identify several risk factors correctly. These findings stress the need to increase knowledge about heart disease, especially among less educated and minority women, and to emphasize the risk of patients' personal status by health providers.

To assess the prevalence of and risk factors for postnatal depressive symptoms in a cohort of mothers of Pacific Island infants in Auckland, New Zealand. The data were gathered as part of the Pacific Island Families Study, in which 1376 mothers were interviewed when their babies were 6 weeks old. The interview included the Edinburgh Postnatal Depression Scale (EPDS). 16.4% of mothers were assessed as probably experiencing depression. Prevalence rates varied from 7.6% for Samoans to 30.9% for Tongans. In addition to ethnicity, risk factors identified by stepwise multiple logistic regression included low Pacific Island acculturation, first birth, stress due to insufficient food, household income less than dollar 40,000, difficulty with transport, dissatisfaction with pregnancy, birth experience, baby's sleep patterns, partner relationship and home. A large prevalence difference between Tongans and other groups remained when the effects of other risk factors were controlled statistically. The prevalence of depressive symptoms among Pacific mothers is at the upper end of the range typically reported. Focus on the overall rate, however, obscures substantial variation between groups. Risk factors are generally similar to those identified in previous research. The findings have implications for prevention and treatment and caution against assuming homogeneity within ethnic categories. Further research is required to explain differences in prevalence between Tongan and other Pacific Island groups.

Unintentional poisoning in young children is an important public health issue. Age pattern studies have demonstrated that children aged 1-3 years have the highest levels of poisoning risk among children aged 0-4 years, yet little research has been conducted regarding risk factors specific to this three-year age group and the methodologies employed varied greatly. The purpose of the current study is to investigate a broad range of potential risk factors for unintentional poisoning in children aged 1-3 years using appropriate methodologies. Four groups of children, one case group (children who had experienced a poisoning event) and three control groups (children who had been 'injured', 'sick' or who were 'healthy'), and their mothers (mother-child dyads) were enrolled into a case-control study. All mother-child dyads participated in a 1.5-hour child developmental screening and observation, with mothers responding to a series of questionnaires at home. Data were analysed as three case-control pairs with multivariate analyses used to control for age and sex differences between child cases and controls. Five risk factors were included in the final multivariate models for one or more case-control pairs. All three models found that children whose mothers used more positive control in their interactions during a structured task had higher odds of poisoning. Two models showed that maternal psychiatric distress increased poisoning risk (poisoning-injury and poisoning-healthy). Individual models identified the following variables as risk factors: less proximal maternal supervision during risk taking activities (poisoning-injury), medicinal substances stored in more accessible locations in bathrooms (poisoning-sick) and lower total parenting stress (poisoning-healthy). The findings of this study indicate that the nature of the caregiver-child relationship and caregiver attributes play an important role in influencing poisoning risk. Further research is warranted to explore the link between caregiver-child relationships and unintentional poisoning risk. Caregiver education should focus on the benefits of close interaction with their child as a prevention measure.

The clinical outcome of extranodal natural killer T-cell lymphoma (ENKTL) has improved substantially as a result of new treatment strategies with non-anthracycline-based chemotherapies and upfront use of concurrent chemoradiotherapy or radiotherapy. A new prognostic model based on the outcomes obtained with these contemporary treatments was warranted. We did a retrospective study of patients with newly diagnosed ENKTL without any previous treatment history for the disease who were given non-anthracycline-based chemotherapies with or without upfront concurrent chemoradiotherapy or radiotherapy with curative intent. A prognostic model to predict overall survival and progression-free survival on the basis of pretreatment clinical and laboratory characteristics was developed by filling a multivariable model on the basis of the dataset with complete data for the selected risk factors for an unbiased prediction model. The final model was applied to the patients who had complete data for the selected risk factors. We did a validation analysis of the prognostic model in an independent cohort. We did multivariate analyses of 527 patients who were included from 38 hospitals in 11 countries in the training cohort. Analyses showed that age greater than 60 years, stage III or IV disease, distant lymph-node involvement, and non-nasal type disease were significantly associated with overall survival and progression-free survival. We used these data as the basis for the prognostic index of natural killer lymphoma (PINK), in which patients are stratified into low-risk (no risk factors), intermediate-risk (one risk factor), or high-risk (two or more risk factors) groups, which were associated with 3-year overall survival of 81% (95% CI 75-86), 62% (55-70), and 25% (20-34), respectively. In the 328 patients with data for Epstein-Barr virus DNA, a detectable viral DNA titre was an independent prognostic factor for overall survival. When these data were added to PINK as the basis for another prognostic index (PINK-E)-which had similar low-risk (zero or one risk factor), intermediate-risk (two risk factors), and high-risk (three or more risk factors) categories-significant associations with overall survival were noted (81% [95% CI 75-87%], 55% (44-66), and 28% (18-40%), respectively). These results were validated and confirmed in an independent cohort, although the PINK-E model was only significantly associated with the high-risk group compared with the low-risk group. PINK and PINK-E are new prognostic models that can be used to develop risk-adapted treatment approaches for patients with ENKTL being treated in the contemporary era of non-anthracycline-based therapy.

In the Netherlands, an Internet-based Chlamydia Screening Implementation was initiated in 3 regions, aiming to reduce population prevalence by annual testing and treatment of people aged 16 to 29 years. We studied who was reached in the first screening round by relating participation and chlamydia positivity to sociodemographic and sexual risk factors. Data from the 2008/2009 screening round were analyzed (261,025 screening invitations, 41,638 participants). Participation rates were adjusted for the sexually active population. Sociodemographic and behavioral correlates of screening participation and positivity were studied by (multilevel) logistic regression models. The overall adjusted participation rate in the first screening round was 19.5% (95% confidence interval, 19.4-19.7) among sexually active people (women, 25%; men, 13%). Sociodemographic factors associated with lower participation were male gender (odds ratio [OR], male 1 vs. female 1.8), young age (OR, 16-19 1 vs. older groups 1.7-2.1), non-Dutch origin (OR between 0.7-0.9), lower education (OR, low 1 vs. high 1.4), high community risk level (0.8), and low socioeconomic status (0.9). Behavioral factors associated with lower participation were a long-standing relationship (0.7) and no reported history or symptoms of sexually transmitted infections (no symptoms, 0.4-0.6) . Factors most strongly related to higher Ct positivity were young age (OR, 1 vs. older groups 0.5-0.8), non-Dutch origin (1.4-2.8), non-Dutch steady partner (1.9-2.7), residence in a high-risk area (1.4-1.5), lower education (high, 0.3-0.5), and a history or symptoms of sexually transmitted infection (no symptoms, 0.4-0.6). Sociodemographic factors associated with lower participation were also associated with higher Ct positivity, showing that high-risk demographic groups are more difficult to mobilize than low-risk groups. Independent of this, higher behavioral risk levels were associated with higher participation rates, suggesting self-selection for screening based on the persons' risk (perception) in both low- and high community risk groups. Our study shows the complexity of the process, including individual and community factors that also interact, when screening for chlamydia.

Previous studies have found the prevalence of lameness in working horses to be 90-100%. Risk factors for lameness in this important equine population, together with risk-reduction strategies adopted by their owners, are poorly understood. The objective was to uncover risk factors for lameness and limb abnormalities in working horses, by associating clinical lameness examination findings on three occasions over two years with owner reported changes in equine management and work practices over this period. Twenty-one communities of horse owners in Jaipur, India, took part in a participatory intervention (PI) project aiming to reduce risk factors for poor welfare, particularly lameness and limb problems. Associations between quantitative measures of equine lameness/limb abnormalities and reported changes in management and work practices were compared with 21 control (C) communities of owners where no intervention had taken place. Key findings from 'complete cases', where the same horse stayed with the same owner for the whole study period (PI group = 73 owners of 83 horses, C group = 58 owners of 66 horses), were that more positive statements of change in equine management and work practices were made by PI group owners than C group owners. A mixed picture of potential risk factors emerged: some reported management improvements, for example reducing the weight of the load for cart animals, were associated with improved limbs and lameness, and others, such as making improvements in shoeing and increasing the age at which their animals started work, with negative outcomes. This study illustrates the complexity and interacting nature of risk factors for lameness in working horses, and highlights the importance of longitudinal investigations that recognise and address this. PI group owners found the project useful and requested similar inputs in future. Our findings demonstrate the value of exploratory and participatory research methodology in the field of working horse welfare.

Our aim was to investigate the association between parental psychosis and potential risk factors for schizophrenia and their interaction. We evaluated whether the factors during pregnancy and birth have a different effect among subjects with and without a history of parental psychosis and whether parental psychosis may even explain their effects on the risk of schizophrenia. The sample comprised 10,526 individuals from the Northern Finland 1966 Birth Cohort. A total of 150 (1.4%) cohort members had schizophrenia by the age of 44 years, of them 18 (12.0%) had a parent with a history of psychosis. In non-psychotic cohort members, this figure was 495 (4.8%). In the parental psychosis group, significant early biological risk factors for schizophrenia included high birth weight (hazard ratio, HR 11.4; 95% confidence interval 3.3-39.7) and length (HR 4.1; 1.3-12.5), high birth weight in relation to gestational age (HR 3.2; 1.1-9.0), and high maternal age (HR 2.6.; 1.0-6.7). High birth weight and length and high maternal education had a significant interaction with parental psychosis. The presence of any biological risk factor increased the risk of schizophrenia significantly only among the parental psychosis group (HR 4.0; 1.5-10.5), whereas the presence of any psychosocial risk factor had no interaction with parental psychosis. Parental psychosis can act as an effect modifier on early risk factors for schizophrenia. Evaluation of the mechanisms behind the risk factors should, therefore, include consideration of the parental history of psychosis. Copyright © 2013 Elsevier B.V. All rights reserved.

To explore the confounding effects of early family factors shared by siblings and cardiovascular risk factors in midlife on the educational differences in mortality from cardiovascular disease (CVD). Data from national and regional health surveys in Norway (1974-2003) were linked with data from the Norwegian Family Based Life Course Study, the National Educational Registry and the Cause of Death Registry. The study population consisted of participants with at least one full sibling among the health survey participants ( n=271,310). Data were available on CVD risk factors, including weight, height, blood pressure, total cholesterol and smoking. The hazards ratio (HR) of CVD mortality was 3.44 (95% confidence interval (CI) 2.98-3.96) in the lowest educational group relative to the highest. The HRs were little altered in the within-sibship analyses. Adjusted for risk factors, the HR for CVD mortality in the cohort analyses was 2.05 (CI 1.77-2.37) in the lowest educational group relative to the highest. The respective HR in the within-sibship analyses was 2.46 (CI 1.48-2.24). Using a sibling design, we did not find that the association between education and CVD mortality was confounded by early life factors shared by siblings, but it was explained to a large extent by CVD risk factors. These results suggest that reducing levels of CVD risk factors could have the greatest effect on mortality in less well-educated people.

HIV-infected men who have sex with men (HIV-MSM) are at high risk of hepatitis C virus (HCV) infection. This study aimed to compare risk factors between HIV-MSM coinfected with HCV and those who are not, in a national representative survey conducted in France. The ANRS VESPA2 survey (April 2011-January 2012) collected sociodemographic and behavioural data (through face-to-face administered questionnaires) as well as medical data (physician questionnaire) among 3022 HIV-infected adults recruited in 73 French HIV hospital departments. We identified behavioural correlates of HCV coinfection among sexually active HIV-MSM who participated in VESPA2 (logistic regression models). Ninety-three of the 1037 HIV-MSM of the study population (8.9%) were coinfected with HCV. The following risk factors were independently associated with HCV coinfection, after adjustment for age and time since HIV diagnosis: current or past injecting drug use, having had at least 20 male sexual partners during the previous 12 months, reporting inconsistent condom use during anal sex with casual partners, and attending sex parties. Individuals reporting at least three sexual risk factors were at the highest risk of being coinfected with HCV (OR (95% CI): 22.86 (9.74; 53.62), p<0.0001). HIV-MSM reporting several sexual risk factors should be sensitised to risk-reduction behaviours to avoid HCV transmission to sexual partners, and infection or reinfection with HCV.

To compare the prevalence of disabling low back pain (DLBP) and disabling wrist/hand pain (DWHP) among groups of workers carrying out similar physical activities in different cultural environments, and to explore explanations for observed differences, we conducted a cross-sectional survey in 18 countries. Standardised questionnaires were used to ascertain pain that interfered with everyday activities and exposure to possible risk factors in 12,426 participants from 47 occupational groups (mostly nurses and office workers). Associations with risk factors were assessed by Poisson regression. The 1-month prevalence of DLBP in nurses varied from 9.6% to 42.6%, and that of DWHP in office workers from 2.2% to 31.6%. Rates of disabling pain at the 2 anatomical sites covaried (r = 0.76), but DLBP tended to be relatively more common in nurses and DWHP in office workers. Established risk factors such as occupational physical activities, psychosocial aspects of work, and tendency to somatise were confirmed, and associations were found also with adverse health beliefs and group awareness of people outside work with musculoskeletal pain. However, after allowance for these risk factors, an up-to 8-fold difference in prevalence remained. Systems of compensation for work-related illness and financial support for health-related incapacity for work appeared to have little influence on the occurrence of symptoms. Our findings indicate large international variation in the prevalence of disabling forearm and back pain among occupational groups carrying out similar tasks, which is only partially explained by the personal and socioeconomic risk factors that were analysed.

Background Previous reviews on risk and protective factors for violence in psychosis have produced contrasting findings. There is therefore a need to clarify the direction and strength of association of risk and protective factors for violent outcomes in individuals with psychosis. Method We conducted a systematic review and meta-analysis using 6 electronic databases (CINAHL, EBSCO, EMBASE, Global Health, PsycINFO, PUBMED) and Google Scholar. Studies were identified that reported factors associated with violence in adults diagnosed, using DSM or ICD criteria, with schizophrenia and other psychoses. We considered non-English language studies and dissertations. Risk and protective factors were meta-analysed if reported in three or more primary studies. Meta-regression examined sources of heterogeneity. A novel meta-epidemiological approach was used to group similar risk factors into one of 10 domains. Sub-group analyses were then used to investigate whether risk domains differed for studies reporting severe violence (rather than aggression or hostility) and studies based in inpatient (rather than outpatient) settings. Findings There were 110 eligible studies reporting on 45,533 individuals, 8,439 (18.5%) of whom were violent. A total of 39,995 (87.8%) were diagnosed with schizophrenia, 209 (0.4%) were diagnosed with bipolar disorder, and 5,329 (11.8%) were diagnosed with other psychoses. Dynamic (or modifiable) risk factors included hostile behaviour, recent drug misuse, non-adherence with psychological therapies (p values<0.001), higher poor impulse control scores, recent substance misuse, recent alcohol misuse (p values<0.01), and non-adherence with medication (p value <0.05). We also examined a number of static factors, the strongest of which were criminal history factors. When restricting outcomes to severe violence, these associations did not change materially. In studies investigating inpatient violence, associations differed in strength but not direction. Conclusion Certain dynamic risk factors are strongly associated with increased violence risk in individuals with psychosis and their role in risk assessment and management warrants further examination.

The inverse graded relationship of education and risk factors of coronary heart disease (CHD) has been reported from Western populations. To examine whether risk factors of CHD are predicted by level of education and influenced by the level of urbanization in Indian industrial populations, a cross-sectional survey (n = 19,973; response rate, 87.6%) was carried out among employees and their family members in 10 medium-to-large industries in highly urban, urban, and periurban regions of India. Information on behavioral, clinical, and biochemical risk factors of CHD was obtained through standardized instruments, and educational status was assessed in terms of the highest educational level attained. Data from 19,969 individuals were used for analysis. Tobacco use and hypertension were significantly more prevalent in the low- (56.6% and 33.8%, respectively) compared with the high-education group (12.5% and 22.7%, respectively; P < 0.001). However, dyslipidemia prevalence was significantly higher in the high-education group (27.1% as compared with 16.9% in the lowest-education group; P < 0.01). When stratified by the level of urbanization, industrial populations located in highly urbanized centers were observed to have an inverse graded relationship (i.e., higher-education groups had lower prevalence) for tobacco use, hypertension, diabetes, and overweight, whereas in less-urbanized locations, we found such a relationship only for tobacco use and hypertension. This study indicates the growing vulnerability of lower socioeconomic groups to CHD. Preventive strategies to reduce major CHD risk factors should focus on effectively addressing these social disparities. PMID:17923677

Deviant peer group affiliation was evaluated as a risk factor for substance use in adolescents with childhood attention-deficit/hyperactivity disorder (ADHD). Results showed that deviant peer affiliation mediated the relationship between ADHD and substance use, suggesting that children with ADHD are more likely than children without ADHD to become involved with deviant peers and, as a result, more likely to use substances. Moreover, the relationship between deviant peer affiliation and substance use was stronger for adolescents with ADHD, suggesting that once they are immersed in a deviant peer group, adolescents with ADHD are more vulnerable to the negative social influences of that group. This study is the first step in identifying high-risk pathways from childhood ADHD to substance use in adolescence. PMID:14640825

Malignant melanoma risk factors have been studied in different geographical area populations. However, no study has focused on risk factors which are more frequently associated to the over 60's age group. A case-control study was performed that included 160 patients age > or = 60 years diagnosed of cutaneous melanoma and 318 controls matched for age and sex. Both groups were assessed, by personal interview and physical examination, for different phenotype characteristics (hair and eye color, phototype), the presence of other cutaneous lesions (solar lentigines, actinic keratoses and nevi), degree and type of solar exposure and personal and family past history of cutaneous or non-cutaneous cancer. Differences were evaluated by contingency tables and univariate and multivariate logistic regression. Of 17 factors, those risk factors with a strong effect on the development of melanoma in the elderly were: fair eyes, severe sunburns, years of occupational sun exposure, smoking, > 50 melanocytic nevi and personal history of NMSC and other non-cutaneous neoplasias. Tobacco smoking is an independent risk factor for cutaneous melanoma in the elderly. Intense (both acute and chronic) sun exposure and constitutional features, such as tumor susceptibility (NMSC, non-cutaneous neoplasias, and multiple nevi) are also associated with melanoma risk. All these factors should help to better design educational campaigns in older people.

Background Intra-dialytic hypertension (IDH) is emerging as an important issue in hemodialysis patients. Its risk factors and clinical outcomes are unclear. Methods A total of 73 prevalent hemodialysis patients were enrolled. They included 14 (19.2%) patients with baseline IDH and 59 patients without IDH. Their clinical parameters, laboratory parameters, and mortality were investigated over 78 months. Results The risks factor of IDH included low serum potassium levels, low ultrafiltration, and low arm muscle area. Lower median survival was evident in the IDH group compared to the non-IDH group, but was not significantly different. After adjusting for relevant confounders for age, the IDH group displayed 2.846 times higher mortality rate than the non-IDH Group (adjusted hazard ratio: 2.846; 95% confidence interval: 1.081–7.490; P = 0.034). Conclusion IDH is associated with high mortality in hemodialysis patients. Clinicians should be aware of the risk factors. Future research studies are needed to explore the mechanisms involved in the association between IDH and mortality. PMID:28742805

To determine the prevalence of strabismus and associated risk factors in southeastern Brazil. A cross-sectional, population-based study using a systematic sample from nine municipalities in a southeastern region of Brazil composed of 1852 individuals aged ≥1 and ≤12 years old was done. Visual acuity (VA), ocular alignment, and refractive error (RE) were evaluated. Strabismic individuals (strabismus group) were compared to orthotropic individuals (orthotropic group) to analyze risk factors linked to heterotropias. Prevalence of strabismus was 0.81% in this population. In the strabismus group, we found 40% with hyperopia, 6.67% with astigmatism, 3.33% with myopia, 6.67% with amblyopia, and 8.33% with moderate anisometropia. In the orthotropic group, 6.85% had hyperopia, 18.12% astigmatism, 14.82% myopia, 0.19% amblyopia, and 4.37% moderate anisometropia. The prevalence of strabismus in southeastern Brazil was 0.81%. Strabismic individuals had more hyperopia. Amblyopia and moderate anisometropia were associated with strabismus.

Gastric cancer is associated with high morbidity and mortality worldwide. To reduce the socioeconomic burden related to gastric cancer, it is very important to identify and manage high risk group for gastric cancer. In this review, we describe the general risk factors for gastric cancer and define high risk group for gastric cancer. We discuss strategies for the effective management of patients for the prevention and early detection of gastric cancer. Atrophic gastritis (AG) and intestinal metaplasia (IM) are the most significant risk factors for gastric cancer. Therefore, the accurate selection of individuals with AG and IM may be a key strategy for the prevention and/or early detection of gastric cancer. Although endoscopic evaluation using enhanced technologies such as narrow band imaging-magnification, the serum pepsinogen test, Helicobacter pylori serology, and trefoil factor 3 have been evaluated, a gold standard method to accurately select individuals with AG and IM has not emerged. In terms of managing patients at high risk of gastric cancer, it remains uncertain whether H. pylori eradication reverses and/or prevents the progression of AG and IM. Although endoscopic surveillance in high risk patients is expected to be beneficial, further prospective studies in large populations are needed to determine the optimal surveillance interval.

The long-standing inverse relationship between education and mortality strengthened substantially at the end of the 20th century. This paper examines the reasons for this increase. We show that behavioral risk factors are not of primary importance. Smoking declined more for the better educated, but not enough to explain the trend. Obesity rose at similar rates across education groups, and control of blood pressure and cholesterol increased fairly uniformly as well. Rather, our results show that the mortality returns to risk factors, and conditional on risk factors, the return to education, have grown over time. PMID:21925754

Intestinal necrosis is the most serious complication of intussusception. The risk factors associated with intestinal necrosis in pediatric patients with intussusception have not been well characterized. This study aimed to investigate the risk factors associated with intestinal necrosis in pediatric patients with failed non-surgical reduction for intussusception. Hospitalized patients who failed the air-enema reduction for intussusception in the outpatient department and subsequently underwent surgery were retrospectively reviewed. All cases were categorized into two groups: intestinal necrosis group and non-intestinal necrosis group based on the surgical findings. Demographic and clinical features including the findings from the surgery were recorded and analyzed. Factors associated with intestinal necrosis were analyzed using univariate and multivariate unconditional logistic regression analyses. A total of 728 cases were included. Among them, 171 had intestinal necrosis at the time of surgery. The group with intestinal necrosis had a longer duration of symptom or length of illness (P = 0.000), and younger (P = 0.000) than the non-intestinal necrosis group. Complex/compound type of intussusceptions is more likely to have intestinal necrosis. Multivariate analysis showed that the presence of grossly bloody stool (OR = 2.12; 95% CI 1.19-3.76, P = 0.010) and duration of symptom (OR = 1.07; 95% CI 1.06-1.08, P = 0.000) were independent risk factors for intestinal necrosis in patients hospitalized for surgical reduction for intussusceptions. At time of admission, the presence of bloody stools and duration of symptom are the important risk factors for developing intestinal necrosis for those patients who failed non-surgical reduction. The length of illness has the highest sensitivity and specificity to correlate with intestinal necrosis. This finding may suggest that we should take the intussusception cases that have the longer duration of symptom directly to operation room for reduction.

Onychomycosis and tinea pedis are common superficial infections caused primarily by dermatophytes. The aim of this investigation was to study the epidemiology, etiological agents, and potential risk factors for infection based on comparison of athletes and non-athletes from a northern region of Rio Grande do Sul (Brazil). Each group consisted of 100 male individuals with ages ranging from 18 to 40 years. After a clinical examination, samples were taken from individuals presenting signs of onychomycosis and/or tinea pedis for direct microscopic examination and culture. Among the athletes, the frequency of onychomycosis and/or tinea pedis was 32%, and for the control group, it was 20%. The athletes presented 16% of onychomycosis, 12% of tinea pedis, and 4% of onychomycosis and tinea pedis together. The distribution in the control group was 10% of onychomycosis, 7% of tinea pedis, and 3% of this association. The pathogens identified were dermatophytes (84.8%) and yeasts (15.2%), and the most commonly identified organism was Trichophyton rubrum, followed by Trichophyton mentagrophytes var. interdigitale. No significant differences were found when the frequency of species distribution in the athletes and non-athlete groups was compared. Risk factors for onychomycosis in athletes included familial cases of fungal infection, contact with domestic animals, and nail trauma, while the risk factors in non-athletes included the habit of not using sandals in public bathrooms and nail trauma. For tinea pedis, the habit of not using sandals in public bathrooms was a predisposing factor in both groups, while hyperhydrosis was a risk factor only in non-athletes. This study concludes that despite the higher number of fungal infections in athletes, there is no significant difference between these groups.

To establish the occurrence of SIDS risk factors (including 'removable' ones) and the incidence of the ecg long QT interval (accepted as a risk factor) and their influence upon infants development and morbidity. A group of 98 infants from normal birth at term to the end of first year of life was observed. The data sources were as follows: 1) a questionnaire filled by mothers before discharge front maternity ward, 2) records of four consecutive medical examinations (including ecg records) performed on 3rd day and 3rd, 6th and 12th month of life. Chi-Square test and Fisher test were used. The most often identified risk factors were: prone sleeping position of infant (60.2%), environmental and maternal tobacco smoking (40.8%) and bed sharing practices (32.6%). A significant but transient signs of delay in psychomotor development (in motor zone) as well as more frequent respiratory tract infections in infants sleeping prone were noted. There were no deaths in the observed group neither cases of long QT interval. 1) the most frequently occurring SIDS risk factors are: environmental tobacco smoking, infant prone sleeping and bed sharing, 2) these inappropriate nursing practices and improper habits of adult family members known as a 'removable' SIDS risk factors have a bad effect on infant health and development, 3) identification of SIDS risk factors in an infant does not predict crib death.

Background Acute poisoning in children is a major preventable cause of morbidity and mortality in both developed and developing countries. However, there is a wide variation in patterns of poisoning and related risk factors across different geographic regions globally. This hospital based case-control study identifies the risk factors of acute unintentional poisoning among children aged 1−5 years of the rural community in a developing Asian country. Methods This hospital based case-control study included 600 children. Each group comprised three hundred children and all children were recruited at Anuradhapura Teaching Hospital, Sri Lanka, over two years (from February 2012 to January 2014). The two groups were compared to identify the effect of 23 proposed risk factors for unintentional poisoning using multivariate analysis in a binary logistic regression model. Results Multivariate analysis identified eight risk factors which were significantly associated with unintentional poisoning. The strongest risk factors were inadequate supervision (95% CI: 15.4–52.6), employed mother (95% CI: 2.9–17.5), parental concern of lack of family support (95% CI: 3.65–83.3), and unsafe storage of household poisons (95% CI: 1.5–4.9). Conclusions Since inadequate supervision, unsafe storage, and unsafe environment are the strongest risk factors for childhood unintentional poisoning, the effect of community education to enhance vigilance, safe storage, and assurance of safe environment should be evaluated.

Urinary tract infection (UTI) is the most common infection posttransplant. However, the risk factors for and the impact of UTIs remain controversial. The aim of this study was to identify the incidence of posttransplant UTIs in a series of renal transplant recipients from deceased donors. Secondary objectives were to identify: (1) the most frequent infectious agents; (2) risk factors related to donor; (3) risk factors related to recipients; and (4) impact of UTI on graft function. This was a retrospective analysis of medical records from renal transplant patients from January to December 2010. Local ethics committee approved the protocol. The incidence of UTI in this series was 34.2%. Risk factors for UTI were older age, (independent of gender), biopsy-proven acute rejection episodes, and kidneys from deceased donors (United Network for Organ Sharing criteria). For female patients, the number of pretransplant pregnancies was an additional risk factor. Recurrent UTI was observed in 44% of patients from the UTI group. The most common infectious agents were Escherichia coli and Klebsiella pneumoniae, for both isolated and recurrent UTI. No difference in renal graft function or immunosuppressive therapy was observed between groups after the 1-year follow-up. In this series, older age, previous pregnancy, kidneys from expanded criteria donors, and biopsy-proven acute rejection episodes were risk factors for posttransplant UTI. Recurrence of UTI was observed in 44%, with no negative impact on graft function or survival. Copyright © 2014 Elsevier Inc. All rights reserved.

In this paper, we summarize exposure-related issues to consider in determining the most appropriate age ranges and life stages for risk assessment. We then propose a harmonized set of age bins for monitoring and assessing risks from exposures to chemicals for global use. The focus is on preconception through adolescence, though the approach should be applicable to additional life stages. A two-tiered set of early life age groups is recommended. The first tier involves the adoption of guidance similar to the childhood age groups recommended by the U.S. Environmental Protection Agency, whereas the second tier consolidates some of those age groups to reduce the burden of developing age-specific exposure factors for different regions. While there is no single "correct" means of choosing a common set of age groups to use internationally in assessing early life exposure and risk, use of a set of defined age groups is recommended to facilitate comparisons of potential exposures and risks around the globe, the collection of data and analyses of aggregate exposure and cumulative risk. Application of these age groups for robust assessment of exposure and risk for specific populations will require region-specific exposure factors as well as local environmental monitoring data.

Diagnosis of cervical spine injuries (CSI) in multitrauma patients, especially in the presence of head trauma, can be difficult. Identification of risk factors associated with CSI can help avoid missed or delayed diagnosis. Trauma registry study of pedestrian injuries caused by being hit by an automobile. Data abstracted for each patient included age, gender, Glasgow Coma Score on admission, Injury Severity Score, Abbreviated Injury Scale (AIS) for each body area, level of cervical spine injuries, and associated injuries. The incidence of spine injuries was derived for 4 age groups (14 years and younger, 15 to 55 years, 56 to 65 years, and older than 65 years). Logistic regression analysis was performed to identify risk factors associated with CSI. There were 8,401 pedestrian injuries caused by automobiles, and 178 patients (2.1%) had CSI. Incidence of CSI increased with age (0.3% in the age group 14 years and younger, 2.2% in the group 15 to 55 years, 3.7% in the group 56 to 65 years, and 4.4% in the group older than 65 years). Using the youngest age group (14 years and younger) as reference, relative risk of CSI in the other groups was 7.0, 12.1, and 14.2, respectively (p < 0.0001). Patients with severe head trauma (AIS > 3) were significantly more likely to have CSI than patients with less severe head injuries (AIS 3), severe chest trauma (AIS > 3), pelvic fracture, and femur fracture as independent risk factors for CSI. Incidence of CSI after injuries to pedestrians hit by automobiles increases with age and severity of head trauma. Age, severe head trauma, severe chest trauma, pelvic fracture, and femur fractures are independent predictors of CSI.

To describe trends in cardiovascular risk factors and change over time across education levels, and study the influence from medicine use and gender. Data from participants (30-74 years) of the Tromsø Study in 1994-1995 (n=22 108) and in 2007-2008 (n=11 565). Blood samples, measurements and self-reported educational level and medicine use were collected. Differences in risk factor levels across education groups were persistent for all risk factors over time, with a more unfavourable pattern in the lowest education group. The exception was cholesterol, with the reduction being largest in the lowest educated, resulting in weakened educational trends over time. While a significant educational trend in cholesterol persisted among the non-users of lipid-lowering drugs (LLD), no educational trend in cholesterol was found among the LLD users in 2007-2008. The strongest educational trends were found for daily smoking and Body Mass Index (BMI). In 2007-2008 the odds for being a smoker were five times higher among the lowest educated compared to the highest educated. In men, the odds for being in the highest quintile of the BMI distribution were, in 2007-2008, almost doubled in the lowest compared to the highest educated. The lowest educated women had 6.2 mm Hg higher mean systolic blood pressure than the highly educated, mean BMI of 26.4 kg/m 2 and smoking prevalence of 37.7%. The difference across education groups for cholesterol levels decreased, while the educational gap persisted over time for the other risk factors. Use of LLD seemed to contribute to the reduction of social differences in cholesterol levels. Published by the BMJ Publishing Group Limited.

The objective of this study was to analyze differences in incidence and epidemiologic risk factors for significant threshold shift (STS) and tinnitus in deployed military personnel diagnosed with mild traumatic brain injury (mTBI) due to either a blast exposure or nonblast head injury. A retrospective longitudinal cohort study of electronic health records of 500 military personnel (456 met inclusion criteria) diagnosed with deployment-related mTBI was completed. Chi-square tests and STS incidence rates were calculated to assess differences between blast-exposed and nonblast groups; relative risks and adjusted odds ratios of developing STS or tinnitus were calculated for risk factors. Risk factors included such characteristics as mechanism of injury, age, race, military occupational specialty, concurrent diagnosis of posttraumatic stress disorder (PTSD), and nicotine use. Among blast-exposed and nonblast patients, 67% and 58%, respectively, developed STS, (P=.06); 59% and 40%, respectively, developed tinnitus (P<.001). Incidence of STS was 24% higher in the blast-exposed than nonblast group. Infantry service was associated with STS; Marine Corps service, PTSD, and zolpidem use were associated with tinnitus. Unprotected noise exposure was associated with both STS and tinnitus. This study highlights potential risk factors for STS and tinnitus among blast-exposed and nonblast mTBI patient groups.

Primary objective of this study was to assess utility of sagittal abdominal diameter (SAD) as a cardio vascular risk predictor and compare various anthropometric measurement of body fat distribution in elderly patients. Four hundred patients were enrolled in study. Elderly patients more than 60 year of age attending medical OPD, geriatric OPD and suitable indoor patients who were willing to participate in the study were included. SAD was significantly higher in patient with ischaemic heart disease (group 1) than patient without ischaemic heart disease (Group 2) (P < 0.001 for male and female). SAD was better than WC to ascertain individual cardio metabolic risk factors in male, especially FBS (Pearson correlation .33 vs. .29), total cholesterol (Pearson correlation .24 vs. .20) as well as LDL cholesterol (Pearson correlation .13 vs. .05), while in female WC and SAD showed equal correlation with individual cardio metabolic risk factors. In patient with metabolic syndrome IHD group showed considerably higher mean SAD values. SAD also showed very good correlation with individual cardio metabolic risk factors especially in elderly male, while in female both SAD and.WC were almost equivalent.

STDs, including HIV, disproportionately affect individuals who have multiple minority identities. Understanding differences in STD risk factors across racial, ethnic and sexual minority groups, as well as genders, is important for tailoring public health interventions. Data from Waves 3 (2001-2002) and 4 (2007-2008) of the National Longitudinal Study of Adolescent Health were used to develop population-based estimates of STD and HIV risk factors among 11,045 young adults (mean age, 29 at Wave 4), by gender, race and ethnicity, and sexual orientation (heterosexual, mixed-oriented, gay). Regression analyses were conducted to examine associations between risk factors and young adults' characteristics. Overall, sexual-minority women in each racial or ethnic group had a higher prevalence of sexual risk behaviors-including a history of multiple partners, forced sex and incarceration-than their heterosexual counterparts. Mixed-oriented women in each racial or ethnic group were more likely than heterosexual white women to have received an STD diagnosis (odds ratios, 1.8-6.4). Black men and sexual-minority men also appeared to be at heightened risk. Gay men in all racial and ethnic groups were significantly more likely than heterosexual white men to report having received an STD diagnosis (2.3-8.3); compared with heterosexual white men, mixed-oriented black men had the highest odds of having received such a diagnosis (15.2). Taking account of multiple minority identities should be an important part of future research and intervention efforts for STD and HIV prevention. Copyright © 2012 by the Guttmacher Institute.

Subclinical hypothyroidism (SCH) is a common endocrine disorder, probably increasing cardiovascular (CV) risk. However, the relation between SCH and atherosclerosis risk factors remains unclear. The aim of the study was to evaluate selected atherosclerosis risk factors in women with SCH in comparison to a group of healthy women and women with overt hypothyroidism, as well as to investigate the influence of L-thyroxine replacement on those risk factors. The study group consisted of 187 obese women aged between 50 and 70 years: 100 women with SCH, 45 women with overt hypothyroidism and 42 women with TSH level in reference ranges. Anthropometric parameters were evaluated. Laboratory tests included thyroid hormones concentrations, lipid profile with apolipoproteins, CRP, homocysteine. Atherosclerotic indexes were calculated: LDL C/HDL C ratio, apoA1/apoB ratio and Castelli risk index. Women with hypothyroidism were given L-thyroxine treatment and after 6 months in euthyroidism the evaluation was repeated. Total cholesterol, LDL-cholesterol and triglycerides concentrations as well as LDL-C/HDL-C ratio and Castelli index were higher in SCH than in controls and decreased after L-thyroxin substitution. All of the calculated atherosclerosis indexes showed significant positive correlations with TSH concentration in SCH group. Also in this group the systolic and diastolic blood pressure decreased significantly after treatment. Dyslipidemia in obese SCH women is not severe, but if untreated for many years, it may lead to atherosclerosis. Substitution therapy improves the lipid profile, changing the relations between protective and proatherogenic fractions of serum lipids, and optimises blood pressure.

Despite international findings that farmers have better health outcomes than other occupation groups, Irish farmers are found to be a high-risk group for cardiovascular disease (CVD). Early detection of CVD through preventive health measurements, such as screening of high-risk groups, can contribute to a reduction of CVD cases. Farmers, however, represent a "challenging" group in terms of engaging in preventive health behaviors. This study examined the prevalence of cardiovascular risk factors among male Irish livestock farmers who participated in heart screening as part of a workplace health intervention. In this cross-sectional study, data were collected from a convenience sample (N = 310) of farmers. Consent included permission to analyze the heart screening results and to participate in two follow-up questionnaires by phone at Week 1 (n = 224) and Week 12 (n = 172). All data were entered onto the Statistical Package for the Social Sciences (SPSS version 22) and both descriptive and inferential statistics were compiled. Almost one in two (46%; n = 140) farmers had high blood pressure (≥140/≥90 mm Hg), and 46% (n = 140) had elevated total cholesterol. One third of farmers were found to be obese (35%; n = 110). The vast majority (83%; n = 255) had at least four risk factors for CVD based on the outcomes of the heart screening. The study findings in relation to obesity and the prevalence of multiple risk factors for CVD are a particular cause of concern and shed considerable light on the current excess burden of CVD among farmers in Ireland.

Objective: To explore the risk factors for lower extremity amputation in patients with diabetic foot. Methods: The clinical data of 1 771 patients with diabetic foot at the Air Force General Hospital of PLA from November 2001 to April 2015 were retrospectively analyzed. The patients were divided into the non-amputation and amputation groups. Within the amputation group, subjects were further divided into the minor and major amputation subgroups. Binary logistic regression analyses were used to assess the association between risk factors and lower extremity amputation. Results: Among 1 771 patients with diabetic foot, 323 of them (18.24%) were in the amputation group (major amputation: 41; minor amputation: 282) and 1 448 (81.76%) in the non-amputation group. Compared with non-amputation patients, those in the amputation group had a longer hospital stay and higher estimated glomerular filtration rate(eGFR)levels. Fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), C-reaction protein (CRP), ESR, ferritin, fibrinogen and WBC levels of the amputation group were higher, while hemoglobin albumin, transferrin, TC, TG, HDL-C and LDL-C were lower than those of the non-amputation group (all P <0.05). The proportion of hypertension(52.48% vs 59.98%), peripheral vascular disease (PAD)(68.11% vs 25.04%), and coronary heart disease(21.33% vs 28.71%)were different between the amputation and non-amputation groups (all P <0.05). Multivariable logistic regression analyses showed that Wagner's grade, PAD and CRP were the independent risk factors associated with lower extremity amputation in hospitalized patients with diabetic foot. Conclusion: Wagner's grade, ischemia of lower limbs and infection are closely associated with amputation of diabetic foot patients.

Important changes in body composition with aging are a progressive loss of muscle mass and increase of fat mass. Despite their enormous clinical importance, body composition changes such as sarcopenic obesity in the elderly are under-recognized. This study aimed to examine the relationship of body composition with a wide variety of cardiometabolic risk factors among 2943 subjects (1250 men and 1693 women) aged 60 years or older from Korean National Health Examination and Nutrition Survey (KNHANES). Sarcopenia was defined as an appendicular skeletal muscle mass (ASM) divided by weight (%) of < 1 SD below the sex-specific mean for young adults. Obesity was defined as a body mass index (BMI) ≥ 25 kg/m(2). Body composition was categorized into four non-overlapping groups: the sarcopenic obese, sarcopenic nonobese, nonsarcopenic obese, and nonsarcopenic nonobese groups. A wide variety of cardiometabolic risk factors, including blood pressure (BP), glucose tolerance indices, lipid profiles, inflammatory markers, and vitamin D level, were compared according to body composition group. The prevalence of sarcopenic obesity was 18.4% in men and 25.8% in women. In both sexes, the prevalence of vitamin D deficiency and metabolic syndrome was highly prevalent in the sarcopenic obese group. Serum insulin level, homeostasis model assessment of insulin resistance (HOMA-IR), triglyceride levels, and ferritin levels were the highest in the sarcopenic obese group in both men and women, whereas HDL-cholesterol and 25-hydroxyvitamin D (25(OH)D) levels were the lowest in the sarcopenic obese group. The sarcopenic obese group was more closely associated with insulin resistance, metabolic syndrome, and cardiovascular disease (CVD) risk factors than any other group in this elderly population.

The development of preventive interventions targeting adolescent problem behaviors requires a thorough understanding of risk and protective factors for such behaviors. However, few studies examine whether different cultural and ethnic groups share these factors. This study is an attempt to fill a gap in research by examining similarities and differences in risk factors across racial and ethnic groups. The social development model has shown promise in organizing predictors of problem behaviors. This article investigates whether a version of that model can be generalized to youth in different racial and ethnic groups (N = 2,055, age range from 11 to 15), including African American (n = 478), Asian Pacific Islander (API) American (n = 491), multiracial (n = 442), and European American (n = 644) youth. The results demonstrate that common risk factors can be applied to adolescents, regardless of their race and ethnicity. The findings also demonstrate that there are racial and ethnic differences in the magnitudes of relationships among factors that affect problem behaviors. Further study is warranted to develop a better understanding of these differential magnitudes. PMID:21625351

To investigate the clinical manifestations and risk factors related to ulcer in patients with ischemic colitis (IC). Clinical data of sixty-three IC patients with definite diagnosis from June 2002 to June 2012 in the PLA General Hospital were retrospectively analyzed. All patients were classified into ulcer group (23 cases) and non-ulcer group (40 cases) according to the presence of ulcer or not. Clinical manifestations and risk factors related to ulcer lesions were compared in the two groups. Logistic regression model was used for statistical analysis. There were 50 men and 13 women enrolled, with an average age of 70 years old. The main clinical manifestations included abdominal pain [85.7% (54/63) ], diarrhea [54.0% (34/63)], hematochezia [41.3% (26/63)]. In comparison with non-ulcer group, the ulcer group showed higher incidences of chronic constipation [34.8% (8/23) vs 12.5% (5/40) , P = 0.03], enteric-coated aspirin intake [52.2% (12/23) vs 25.0% (10/40), P = 0.03] and abdomen tenderness [82.6% (19/23) vs 52.5% (21/40), P = 0.02]. Chronic constipation and enteric-coated aspirin intake were independent risk factors related to ulcer lesions (OR = 3.38, P = 0.04; OR = 5.91, P = 0.03). Patients with abdomen tenderness had higher incidence of ulcer lesion (OR = 3.12, P = 0.04). The most common location of IC was left colon [69.8% (44/63)]. No difference of site distribution was found in ulcer and non-ulcer group (P = 0.066). Splanchnic atherosclerosis in the ulcer group was more common than in non-ulcer group [88.2% (15/17) vs 58.3% (14/24), P = 0.038]. The duration of hospitalization was significantly longer in ulcer group [ (14.3 ± 7.1) d vs (6.2 ± 4.1) d, P < 0.01]. Higher white blood cell (WBC) count and lower hemoglobin (Hb) were seen in ulcer group than those in non-ulcer group [(10.17 ± 3.32) ×10(9)/L vs (7.25 ± 3.15)×10(9)/L, P = 0.018; (98 ± 27) g/L vs (126 ± 35) g/L, P = 0.041]. Chronic constipation, enteric-coated aspirin intake and splanchnic atherosclerosis are risk factors related to ulcer in IC patients. Abdomen tenderness, high WBC and low Hb strongly indicate possible IC with ulcer.

The National Institute for Health and Clinical Excellence (NICE) has recently released obesity guidelines for health risk. For the first time in the UK, we estimate the utility of these guidelines by relating them to the established cardiovascular disease (CVD) risk factors. Health Survey for England (HSE) 2006, a population-based cross-sectional study in England was used with a sample size of 7225 men and women aged ≥35 years (age range: 35-97 years). The following CVD risk factor outcomes were used: hypertension, diabetes, total and high density lipoprotein cholesterol, glycated haemoglobin, fibrinogen, C-reactive protein and Framingham risk score. Four NICE categories of obesity were created based on body mass index (BMI) and waist circumference (WC): no risk (up to normal BMI and low/high WC); increased risk (normal BMI & very high WC, or obese & low WC); high risk (overweight & very high WC, or obese & high WC); and very high risk (obese I & very high WC or obese II/III with any levels of WC. Men and women in the very high risk category had the highest odds ratios (OR) of having unfavourable CVD risk factors compared to those in the no risk category. For example, the OR of having hypertension for those in the very high risk category of the NICE obesity groupings was 2.57 (95% confidence interval 2.06 to 3.21) in men, and 2.15 (1.75 to 2.64) in women. Moreover, a dose-response association between the adiposity groups and most of the CVD risk factors was observed except total cholesterol in men and low HDL in women. Similar results were apparent when the Framingham risk score was the outcome of interest. In conclusion, the current NICE definitions of obesity show utility for a range of CVD risk factors and CVD risk in both men and women.

The prognostic value of the metabolic syndrome (MetS) is believed to vary with age. With an elderly population expecting to triple by 2060, it is important to evaluate the validity of MetS in this age group. We examined the association of MetS risk factors with later risk of type 2 diabetes (T2DM) and cardiovascular disease (CVD) in elderly Caucasian women. We further investigated if stratification of individuals not defined with MetS would add predictive power in defining future disease prevalence of individuals with MetS.The Prospective Epidemiological Risk Factor Study, a community-based cohort study, followed 3905 Danish women since 2000 (age: 70.1 ± 6.5) with no previous diagnosis of T2DM or CVD, holding all measurements used for MetS definition; central obesity, hypertension, hyperlipidemia, and hyperglycemia combined with register-based follow-up information.Elderly women with defined MetS presented a 6.3-fold increased risk of T2DM (95% confidence interval: [3.74-10.50]) and 1.7-fold increased risk of CVD (1.44-2.05) compared to women with no MetS risk factors. Subdividing the control group without defined MetS revealed that both centrally obese controls and controls holding other MetS risk factors also had increased risk of T2DM (hazard ratio (HR) = 2.21 [1.25-3.93] and HR = 1.75 [1.04-2.96]) and CVD (HR = 1.51 [1.25-1.83] and HR = 1.36 [1.15-1.60]) when compared to controls with no MetS risk factors.MetS in elderly Caucasian women increased risk of future T2DM and CVD. While not defined with MetS, women holding only some risk factors for MetS were also at increased risk of T2DM or CVD compared to women with no MetS risk factors.

Idiopathic inflammatory myopathies are systemic autoimmune diseases characterized by progressive proximal muscle weakness. Cancer-associated myositis represents the worst prognostic group within this heterogeneous disease. The aim of this study was to reveal factors which increase the risk factors for association of cancerous disease in patients with myositis. Furthermore, the authors explored the most common types of associated malignancies in their patients with myositis and characterize the clinical findings in a sub-group of anti-p155/140 positive patients. In this retrospective study, myositis patients with and without associated cancer were analysed (32 and 64 patients, respectively). In addition, anti-p155/140 positive and negative groups were compared, irrespective to the presence of associated malignancies. The risk for associated malignancy was higher in patients with severe muscle and skin symptoms and those with dermatomyositis. Furthermore, increased risk for malignancy was noted in the presence of particular skin symptoms and the absence of systemic symptoms. The anti-p155/140 antibody was proved to be a feasible marker of an independent clinical sub-group which overlapped clinical characteristics with cancer-associated myositis. These results may help the identification of patients with myositis with a higher risk for associated malignancy.

The high rate of violence in the healthcare sector supports the need for greater surveillance efforts. The purpose of this study was to use a province-wide workplace incident reporting system to calculate rates and identify risk factors for violence in the British Columbia healthcare industry by occupational groups, including nursing. Data were extracted for a 1-year period (2004-2005) from the Workplace Health Indicator Tracking and Evaluation database for all employee reports of violence incidents for four of the six British Columbia health authorities. Risk factors for violence were identified through comparisons of incident rates (number of incidents/100,000 worked hours) by work characteristics, including nursing occupations and work units, and by regression models adjusted for demographic factors. Across health authorities, three groups at particularly high risk for violence were identified: very small healthcare facilities [rate ratios (RR) = 6.58, 95% CI =3.49, 12.41], the care aide occupation (RR = 10.05, 95% CI = 6.72, 15.05), and paediatric departments in acute care hospitals (RR = 2.22, 95% CI = 1.05, 4.67). The three high-risk groups warrant targeted prevention or intervention efforts be implemented. The identification of high-risk groups supports the importance of a province-wide surveillance system for public health planning.

Callous-unemotional (CU) traits are a risk factor for a severe, aggressive, and persistent pattern of conduct problems (CP). This study investigated characteristics that might differentiate children with elevated CU traits with and without CP in an effort to identify factors that may reduce the risk for CP in children with limited prosocial emotions. Utilizing a sample of 1,366 children from Cyprus, five groups were identified for further study based on latent profile analysis: low-risk (67.2%), high-CP/low-CU (7.9%), high-CU (9.4%), moderate-CP/CU (8.4%), and high-CP/CU (7.2%). The identified groups were compared on behavioral and social measures. There were significant main effects of group for: impulsivity and executive functioning; parenting; and connectedness to school. The high-CU group had significantly lower hyperactivity-impulsivity and executive functioning deficits, significantly higher self-regulation, and their mothers reported more maternal involvement and positive parenting than those in the high-CP/CU group. Also, the high-CU group showed more school connectedness than those in the high-CP/CU group. These findings highlight several factors in the child and in his or her social environment that are associated with CU traits in the absence of serious CP and that may suggest targets for intervention for youth who may lack prosocial emotions. © 2016 Association for Child and Adolescent Mental Health.

Do arterial stiffness and wave reflection underlie cardiovascular risk in ethnic minorities?

PubMed

Faconti, Luca; Nanino, Elisa; Mills, Charlotte E; Cruickshank, Kennedy J

2016-01-01

Increasing evidence indicates that remarkable differences in cardiovascular risk between ethnic groups cannot be fully explained by traditional risk factors such as hypertension, diabetes or dislipidemia measured in midlife. Therefore, the underlying pathophysiology leading to this "excess risk" in ethnic minority groups is still poorly understood, and one way to address this issue is to shift the focus from "risk" to examine target organs, particularly blood vessels and their arterial properties more directly. In fact, structural and functional changes of the vascular system may be identifiable at very early stages of life when traditional factors are not yet developed. Arterial stiffening, measured as aortic pulse wave velocity, and wave reflection parameters, especially augmentation index, seem to be an important pathophysiological mechanism for the development of cardiovascular disease and predict mortality independent of other risk factors. However, data regarding these arterial indices in ethnic minorities are relatively rare and the heterogeneity between populations, techniques and statistical methods make it difficult to fully understand their role.

Hispanic women who are 50 years of age and older have been shown to be at increased risk of acquiring HIV infection due to age and culturally related issues. The purpose of our study was to investigate factors that increase HIV risk among older Hispanic women (OHW) as a basis for development or adaptation of an age and culturally tailored intervention designed to prevent HIV-related risk behaviors. We used a qualitative descriptive approach. Five focus groups were conducted in Miami, Florida, with 50 participants. Focus group discussions centered around eight major themes: intimate partner violence (IPV), perimenopausal-postmenopausal-related biological changes, cultural factors that interfere with HIV prevention, emotional and psychological changes, HIV knowledge, HIV risk perception, HIV risk behaviors, and HIV testing. Findings from our study stressed the importance of nurses' roles in educating OHW regarding IPV and HIV prevention. Copyright © 2013 Association of Nurses in AIDS Care. Published by Elsevier Inc.

Annexin A5 is a placental anti-coagulant protein that contains four nucleotide substitutions (M2 haplotype) in its promoter. This haplotype is a risk factor for recurrent spontaneous abortion (RSA). The influence of the M2 haplotype in the gestational timing of spontaneous abortions, paternal risk and relationships with known risk factors were investigated. European couples (n = 500) who had experienced three or more consecutive spontaneous abortions, and two fertile control groups, were selected for this study. The allele frequency of M2 was significantly higher among patients who had experienced early RSA than among controls (P = 0.002). No difference was found between controls and patients who had undergone late spontaneous abortions. No difference was found between patients who had experienced RSA who had a live birth or no live births, or between patients who were positive or negative for known risk factors. Male and female partners in each group had similar allele frequencies of M2. The M2 haplotype is a risk factor for early spontaneous abortions, before the 12th week of gestation, and confers about the same relative risk to carriers of both sexes. Having one or more M2 allele(s) in combination with other risk factors further increases the RSA risk. Copyright © 2015 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

Cardiovascular risk factors levels of Pacific people in a New Zealand multicultural workforce.

To compare cardiovascular risk factors among the major Pacific Island communities participating in a New Zealand multicultural workforce survey. There were 650 employed Pacific Island participants (Samoan 357, Cook Islands 177, Tongan 71, Niuean 45), aged 40-65 years, who were interviewed in a work-based, cross-sectional survey. During an oral glucose tolerance test, blood samples were collected for determination of blood glucose and serum lipids. Participants provided information on smoking and leisure time physical activity. Blood pressure, weight and height were measured and body mass index calculated. Ten-year risk of cardiovascular disease was calculated using equations from the Framingham study. Among men, their ten-year risk of a cardiovascular event was similar for the four communities compared (range 11.5% to 13.2%). However, individual risk factors did vary between the ethnic groups with Cook Island men having significantly higher total cholesterol, blood pressure and urinary microalbumin than other Pacific Island ethnic groups, while Tongan men were more likely to smoke and had lower HDL levels than other groups. Among women, Samoan and Cook Island participants had significantly higher ten-year cardiovascular risk scores (5.7%) than Niuean (4.4%) and Tongan (3.7%), due primarily to elevated total cholesterol levels. Cardiovascular risk factor levels vary between Pacific Islands communities in New Zealand. Targeted interventions to specific Pacific communities may be more beneficial than the current homogeneous prevention strategy applied to all communities.

We examined whether high-sensitivity C-reactive protein (hsCRP) ≥2.0 mg/L was associated with increased intima-media thickness (IMT), plaque burden, and plaque echolucency in carotid arteries. Women (n = 635) from a population sample of 64-year-old females with varying degrees of glucose tolerance underwent risk factor assessment, measurement of hsCRP, and ultrasound examinations of the carotid arteries. Participants with hsCRP levels ≥2.0 mg/L had elevated carotid bulb IMT independently of other cardiovascular risk factors compared with those with hsCRP <2.0 mg/L. The participants with plaques in the highhsCRP group had larger total plaque area compared to those with plaque in the lower hsCRP group. Plaque echolucency did not differ between groups. High-sensitivity CRP levels ≥2.0 mg/L were accompanied by elevated IMT in the carotid bulbs independently of other cardiovascular risk factors. Total plaque area was larger among women with plaques in the high hsCRP group versus the lower hsCRP group.

Falls are common in community-dwelling elderly persons and are a frequent source of morbidity. Simple indices to prospectively stratify people into categories at different fall-risk would be useful to health care practitioners. Our goal was to develop a fall-risk index that discriminated between people at high and low risk of falling. We evaluated the risk of falling over a one-year period in 557 elderly persons (mean age 81.6) living in a retirement community. On the baseline interview, we asked subjects if they had fallen in the previous year and evaluated risk factors in six additional conceptual categories. On the follow-up interview one year later, we again asked subjects if they had fallen in the prior year. We evaluated risk factors in the different conceptual categories and used logistic regression to determine the independent predictors of falling over a one-year period. We used these independent predictors to create a fall-risk index. We compared the ability of a prior falls history with other risk factors and with the combination of a falls history and other risk factors to discriminate fallers from nonfallers. A fall in the previous year (OR = 2.42, 95% CI = 1.49-3.93), a symptom of either balance difficulty or dizziness (OR = 1.83, 95% CI = 1.16-2.89), or an abnormal mobility exam (OR = 2.64, 95% CI = 1.64-4.26) were independent predictors of falling over the subsequent year. These three risk factors together (c statistic =.71) discriminated fallers from nonfallers better than previous history of falls alone (c statistic =.61) or the symptomatic and exam risk factors alone (c statistic =.68). When combined into a risk index, the three independent risk factors stratify people into groups whose risk for falling over the subsequent year ranges from 10% to 51%. A history of falling over the prior year, a risk factor that can be obtained from a clinical history (balance difficulty or dizziness), and a risk factor that can be obtained from a physical exam (mobility difficulty) stratify people into groups at low and high risk of falling over the subsequent year. This risk index may provide a simple method of assessing fall risk in community-dwelling elderly persons. However, it requires validation in other subjects before it can be recommended for widespread use.

This study aimed to explore and quantify the selection process to guide the decision on closure type (myocutaneous flap repair (MFR) or primary closure) for people undergoing pelvic exenteration. This was a retrospective analysis of a prospectively maintained database with review of hospital records for verification and capture of missing data. Associations between four risk factors (previous radiotherapy, previous abdominoperineal resection, need for total exenteration, need for sacrectomy) were assessed individually and collectively as predictors of closure type and wound complications. A total of 203 pelvic exenteration procedures were reviewed (75 primary and 122 recurrent cancers). Thirty-nine patients (19·2 per cent) had MFR and 164 (80·8 per cent) primary closure. Patients who had MFR were significantly more likely to exhibit each risk factor, confirming the selective decision process. MFR had higher rates of complications across all four risk factors, individually and combined. In the primary closure group, there was a significant correlation between the number of risk factors and the proportion of patients with a complication (r = 0·25, P = 0·008). In contrast, no such relationship was found for the MFR group (r = 0·01, P = 0·973). Among patients who had any complication, the primary closure group had significantly lower rates of any wound dehiscence (15 of 64 versus 17 of 28; P < 0·001) and total infection (16 of 64 versus 14 of 28; P = 0·019) compared with the MFR group. Rates of wound and septic complications after pelvic exenteration were low in patients with fewer than two risk factors who had a primary closure. MFR had significantly higher complication rates, and should be reserved for patients with two or more risk factors or extensive skin involvement.

Racial/ethnic differences in representation, substance use, and its correlates may be linked to differential long-term health outcomes for justice-involved youth. Determining the nature of these differences is critical to informing more efficacious health prevention and intervention efforts. In this study, we employed a theory-based approach to evaluate the nature of these potential differences. Specifically, we hypothesized that (1) racial/ethnic minority youth would be comparatively overrepresented in the juvenile justice system, (2) the rates of substance use would be different across racial/ethnic groups, and (3) individual-level risk factors would be better predictors of substance use for Caucasian youth than for youth of other racial/ethnic groups. To evaluate these hypotheses, we recruited a large, diverse sample of justice-involved youth in the southwest (N = 651; M age = 15.7, SD = 1.05, range = 14-18 years); 66% male; 41% Hispanic, 24% African American, 15% Caucasian, 11% American Indian/Alaska Native). All youth were queried about their substance use behavior (alcohol, marijuana, tobacco, illicit hard drug use) and individual-level risk factors (school involvement, employment, self-esteem, level of externalizing behaviors). As predicted, racial/ethnic minority youth were significantly overrepresented in the juvenile justice system. Additionally, Caucasian youth reported the greatest rates of substance use and substance-related individual-level risk factors. In contrast, African American youth showed the lowest rates for substance use and individual risk factors. Contrary to predictions, a racial/ethnic group by risk factor finding emerged for only one risk factor and one substance use category. This research highlights the importance of more closely examining racial/ethnic differences in justice populations, as there are likely to be differing health needs, and subsequent treatment approaches, by racial/ethnic group for justice-involved youth. Additionally, this study highlights the need for timely, empirically supported (developmentally and cross-culturally) substance abuse interventions for all justice-involved youth.

Ever since its introduction in 1977, a minimum of few months of period is required for osseointegration to take place after dental implant surgery. With the passage of time and advancements in the fields of dental implant, this healing period is getting smaller and smaller. Immediate loading of dental implants is becoming a very popular procedure in the recent time. Hence, we retrospectively analyzed the various risk factors for the failure of delayed and immediate loaded dental implants. In the present study, retrospective analysis of all the patients was done who underwent dental implant surgeries either by immediate loading procedure or by delayed loading procedures. All the patients were divided broadly into two groups with one group containing patients in which delayed loaded dental implants were placed while other consisted of patients in whom immediate loaded dental implants were placed. All the patients in whom follow-up records were missing and who had past medical history of any systemic diseases were excluded from the present study. Evaluation of associated possible risk factors was done by classifying the predictable factors as primary and secondary factors. All the results were analyzed by Statistical Package for the Social Sciences (SPSS) software. Kaplan-Meier survival analyses and chi-square test were used for assessment of level of significance. In delayed and immediate group of dental implants, mean age of the patients was 54.2 and 54.8 years respectively. Statistically significant results were obtained while comparing the clinical parameters of the dental implants in both the groups while demographic parameters showed nonsignificant correlation. Significant higher risk of dental implant failure is associated with immediate loaded dental implants. Tobacco smoking, shorter implant size, and other risk factors play a significant role in predicting the success and failure of dental implants. Delayed loaded dental implant placement should be preferred as they are associated with decreased risk of implant failure.

Suicide rates are highest among the elderly in Switzerland. The estimated number of unreported cases is particularly high in this age group. The risk factors are multidimensional, including depression and social isolation. The detection and management of the controllable risk factors, foremost depression, is of particular importance for suicide prevention. Old age depression often shows an atypical presentation, is misinterpreted as a normal process of aging and is not adequately treated.

The present study aimed to explore the association between autonomic dysfunction and measurements of atherosclerosis in a middle-aged and elderly Chinese population. A population-based cross-sectional study was performed in Shanghai, China, from March to August 2010, with 5076 participants included in the analysis. Autonomic function was assessed by a novel EZSCAN test based on sudomotor function analysis. Carotid intima-media thickness (CIMT) was measured using B-mode ultrasonography and brachial-ankle pulse wave velocity (ba-PWV) was measured using an autonomic device. Participants were divided into three groups based on EZSCAN values: Group 1: EZSCAN 0-24; Group 2, EZSCAN 25-49; and Group 3, EZSCAN 50-100. These groups denoted autonomic dysfunction risk groups as follows: no risk, moderate risk and high risk, respectively. The prevalence of elevated CIMT and ba-PWV increased markedly with increasing EZSCAN values (elevated CIMT 7.4%, 17.5%, and 29.7%, elevated ba-PWV 3.2%, 19.7%, and 36.5%, in Groups 1, 2, and 3, respectively; both Ptrend < 0.0001). Logistic regressions revealed that EZSCAN values ≥50 were associated with a non-significantly higher risk of elevated CIMT (odds ratio [OR] = 1.43; 95% confidence interval [CI] 0.98-2.07) and a significantly higher risk of elevated ba-PWV (OR = 2.16; 95% CI 1.25-3.71) compared with EZSCAN values <25, after controlling for conventional risk factors. A higher EZSCAN value (≥50), an index of high autonomic dysfunction risk, was associated with an increased risk of elevated ba-PWV and CIMT. Such associations were partially explained by traditional atherosclerotic risk factors. © 2014 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

The risk factors responsible for acute rheumatic fever (ARF) are complex, in part, because group A streptococcus (GAS) infection is a prerequisite for this disease. We attempted to differentiate socioeconomic from genetic risk factors by studying subjects in a Hawaii pediatric cardiology clinic who qualified for Medicaid. This ethnically diverse group was unique because they maintained a low socioeconomic but generally healthy lifestyle with more limited risks than those living in extremely impoverished conditions. Methods Questionnaires were administered to consenting subjects in the clinic, who were divided into those diagnosed with ARF (n=26) and those with other (primarily congenital) heart diseases (n=41). Results The socioeconomic status of the ARF and non-ARF groups was lower than that of the Hawaii population in general, and little differences were noted between the groups. The ARF group, however, had slightly larger household sizes and more children than the non-ARF group. The greatest difference was in ethnicity. By the Fisher exact test, the number of Polynesians belonging to the ARF group was significantly greater than all other ethnicities (P=.005). Polynesians had an odds ratio >4.80 of developing ARF, which increased to 6.33 when number of children per household was considered. Conclusion The potential contribution of genetic predisposing factors for developing ARF was analyzed in subjects living in a homogeneously low socioeconomic level relative to the general Hawaii population. Polynesians were at highest risk when compared to other ethnicities living in similar socioeconomic conditions. PMID:17200684

To reveal the effect of diet, bowel functions and toilet habits on the development of anal fissure. One hundred patients complaining of anal fissure were included to the case group; and one hundred age- and gender-matched patients referred for other reasons except for anorectal complaints were included to the control group. The information was obtained by face to face interviews using questionnaires. Statistically significant differences were found in coffee, fruit, and meat consumption between the groups. The patients suffering from anal fissure avoided paprika consumption. The rate of anal fissure incidence was higher in squat toilet users. This study is the first study which evaluates the risk factors such as paprika consumption and squat toilet usage that are specific to Eastern culture. Further studies including large numbers of population are needed to evaluate different risk factors for anal fissure development (Tab. 2, Ref. 11). Full Text (Free, PDF) www.bmj.sk.

Work ability is partly determined by physical and mental fitness. Bench step exercise can be practiced anywhere at any time. The aim of this study was to determine the effects of a bench step exercise on work ability by examining cardiovascular risk factors and oxidative stress. Thirteen volunteers working in a warehousing industry comprised the bench step exercise group (n=7) and the control group (n=6). The participants in the step exercise group were encouraged to practice the step exercise at home for 16 weeks. The step exercise improved glucose metabolism and antioxidative capacity and increased work ability by reducing absences from work and improving the prognosis of work ability. The improvement in work ability was related to a reduction in oxidative stress. These results suggest that a bench step exercise may improve work ability by reducing cardiovascular risk factors and oxidative stress.

Past research indicates ethnicity may be related to eating disorder and related risk factors. The present study examines risk factors for eating disorders in 50 Anglo- and 50 Greek-Australian girls (mean age = 13.5 years). The variables assessed included bulimic tendencies, body dissatisfaction, use of extreme weight loss behaviors (EWLBs), self-esteem, depression and family cohesion and adaptability. Cultural eating patterns were also explored. A stepwise discriminant function analysis to examine whether the two groups could be discriminated on these variables was significant and correctly classified 73.9% of the sample, the chief discriminating variables being Pressure to Eat, EWLBs, and Family Adaptability. Univariate analyses indicated differences between the groups on Pressure to Eat, Family Adaptability, and Mother's Shape. Although the groups were discriminable, a number of variables generally associated with eating disorder did not contribute to the function. These data are discussed in terms of cultural assimilation.

To investigate the risk factors for anorexia in children, and to reduce the prevalence of anorexia in children. A questionnaire survey and a case-control study were used to collect the general information of 150 children with anorexia (case group) and 150 normal children (control group). Univariate analysis and multivariate logistic stepwise regression analysis were performed to identify the risk factors for anorexia in children. The results of the univariate analysis showed significant differences between the case and control groups in the age in months when supplementary food were added, feeding pattern, whether they liked meat, vegetables and salty food, whether they often took snacks and beverages, whether they liked to play while eating, and whether their parents asked them to eat food on time (P<0.05). The results of the multivariate logistic regression analysis showed that late addition of supplementary food (OR=5.408), high frequency of taking snacks and/or drinks (OR=11.813), and eating while playing (OR=6.654) were major risk factors for anorexia in children. Liking of meat (OR=0.093) and vegetables (OR=0.272) and eating on time required by parents (OR=0.079) were protective factors against anorexia in children. Timely addition of supplementary food, a proper diet, and development of children's proper eating and living habits can reduce the incidence of anorexia in children.

Precise patient selection criteria are necessary to guide the surgeon in selecting laparoscopic repair for patients with perforated peptic ulcers. The aims of this study are to report surgical outcomes after surgery for perforated duodenal ulcers and identify risk factors for predicting failure of laparoscopic simple closure for perforated duodenal ulcer. In total, 77 patients who underwent laparoscopic simple closure for perforated duodenal ulcers from January 2007 to September 2013 were retrospectively analyzed. Patients were divided into totally laparoscopic and conversion groups. The characteristics of patients, intraoperative findings, postoperative complications, conversion rates and suture leakage rates of each group were investigated. Laparoscopic repair was completed in 69 (89.6%) of 77 patients, while 8 (10.4%) underwent conversion to open repair. Patients in the conversion group had longer perforation time, larger perforation size, more suture leakage, longer hospital stay, and higher 30-day mortality rate than those in the totally laparoscopic group. The size of perforation was the only risk factor for conversion in multivariable analysis. Patients with an ulcer perforation size of ≥9 mm or with perforation duration of ≥12.5 h had a significantly increased risk for conversion and suture leakage. Ulcer size of ≥9 mm is a significant risk factor for predicting conversion in laparoscopic simple closure. Suture leakage is associated with ulcer size (9 mm) and duration of perforation (12.5 h).

The sociohygienic risk factors of tuberculosis were assessed in 253 reproductive-aged women from Izhevsk to develop social and medical prophylactic measures. There is evidence that living conditions, income and education levels, nutrition quality, marital and employment status are of particular importance among the social risk factors of tuberculosis. The low levels of medical activity and hygienic literacy, poor awareness of prophylactic measures against tuberculosis largely favors the untimely detection and spread of tuberculosis infection among the population, including women of reproductive age. In this connection, healthcare workers should activate work on the publicity of health-saving lifestyle and on the prevention of tuberculosis. The analysis indicated that 83.5% of the female patients with tuberculosis were detected from the disease risk groups, prophylactic work with this group will therefore prevent the occurrence of new cases and reduce morbidity of this pathology.

Patterns of risk for anxiety-depression amongst Vietnamese-immigrants: a comparison with source and host populations

PubMed Central

2013-01-01

Background Studies suggest that immigrants have higher rates of anxiety-depression than compatriots in low-middle income countries and lower rates than populations in host high income countries. Elucidating the factors that underlie these stepwise variations in prevalence may throw new light on the pathogenesis of anxiety-depressive disorders globally. This study aimed to examine whether quantitative differences in exposure to, or the interaction between, risk factors account for these anxiety-depression prevalence differences amongst immigrant relative to source and host country populations. Methods Multistage population mental health surveys were conducted in three groups: 1) a Vietnamese-immigrant sample settled in Australia (n = 1161); 2) a Vietnamese source country sample residing in the Mekong Delta region (n = 3039); 3) an Australian-born host country sample (n = 7964). Multivariable logistic regression analyses compared risk factors between the Vietnamese-immigrant group and: 1) the Mekong Delta Vietnamese; and 2) the Australian-born group. Twelve month anxiety-depression diagnoses were the main outcome measures, derived from the Composite International Diagnostic Interview (CIDI), supplemented by an indigenously derived measure - the Phan Vietnamese Psychiatric Scale (PVPS) in both Vietnamese groups. Results The 12-month prevalence of anxiety-depression showed a stepwise increase across groups: Mekong Delta Vietnamese 4.8%; Vietnamese-immigrants 7.0%; Australian-born 10.2%. The two Vietnamese populations showed a similar risk profile with older age, exposure to potentially traumatic events (PTEs), multiple physical illnesses and substance use disorder (SUD) being associated with anxiety-depression, with the older Vietnamese-immigrants reporting greater exposure to these factors. The interaction between key risk factors differed fundamentally when comparing Vietnamese-immigrant and Australian-born samples. Age emerged as the major discriminator, with young Vietnamese-immigrants exhibiting particularly low rates of anxiety-depression. Conclusions The findings reported here suggest that core risk factors for anxiety-depression may be universal, but their patterning and interaction may differ according to country-of-origin. The study also highlights the importance of including both standard international and culturally-specific measures to index cross-cultural manifestations of common mental disorders. PMID:24294940

We examined the effect of sociodemographic factors, cancer, and psychiatric disorders on suicide by gender and age-specific patterns in South Korea. The study is a case-control study. Claim data was obtained from the national health insurance database and national death registration database. The number of people who committed suicide was 11,523, which was matched with a control group consisting of ten times as many people at 115,230 selected from the national health insurance and medical aids beneficiaries. The medical utilization of the case group was one year before death and that of the control group was from July 1,2003 to June 30, 2004. Four variables-address, economic status, presence of a psychiatric disease, and cancer-were used in multiple logistic regression analyses. Living in cities or in rural areas showed a greater risk for suicide than living in a metropolitan city. Low economic status, the presence of a psychiatric disorder, and cancer were also statistically meaningful risk factors for suicide. The three major psychiatric diseases, schizophrenia, alcohol abuse, and bipolar disorder, were meaningful in all age groups, but the scale of the odds ratio differed by the age group. Only the psychiatric disorder variable was meaningful in the adolescent group, whereas a psychiatric disorder and economic status were meaningful for the young adult group, and all variables were meaningful for the middle-aged group. A psychiatric disorder and cancer were meaningful in the elderly group, economic status was meaningful for male subjects, and address was meaningful for female subjects. Factors such as living in city or rural areas, low economic status, the presence of a psychiatric disorder, and cancer were statistically meaningful risk factors in suicide. These factors also differed by age group. Therefore, policymakers should establish policies for suicide prevention that are relevant for each age group.

The objective of this study was to examine the relationship between selected risk factors at the workplace and health indices in relation to nutritional habits and nutritional status in industrial workers. Exposure to physical and chemical risk factors and their impact on health in the province of Szczecin and in Poland was evaluated basing on data published in the Yearbooks of the Province of Szczecin, the Central Statistics Bureau (GUS) and Regional Inspectorate of Labor (OIP) in Szczecin. A random selection of plants in Szczecin was done and workplaces with chemical and physical risk levels exceeding the highest acceptable values were identified. Measurements of concentrations of chemicals and intensity of physical factors were performed by Work Environment Research Laboratories of the plants and by the laboratory of the Sanitary and Epidemiological Center in Szczecin. Eighty-eight men exposed to occupational risk factors were randomly selected. The mean period of exposure in that group was approximately ten years. The control group was composed of male workers (n = 83) not exposed to any of the risk factors in question (Tab. 3). Nutritional habits and nutritional status were studied during summer/autumn and winter/spring periods. Dietary survey consisted of the last 24-hour nutrient intake questionnaire. Nutritional status evaluation was based on body mass index (BMI) values and results of the following laboratory tests: blood cell count, levels of total protein, prealbumin, retinol binding protein (RBP), magnesium, inorganic phosphorus, and ascorbic acid. The following results were obtained: 1. Physical factors constituted the most frequent source of occupational risk in the province of Szczecin and in Poland in 1990-1994 (Tab. 1); 2. The incidence of occupational risk and occupational disease morbidity rates in 1990-1994 were lower for the province of Szczecin than the average for Poland; 3. The rate of fatal accidents at work in 1982-1994 was higher for the province of Szczecin than the average for Poland (Tab. 2); 4. Differences in dietary habits between the study and control groups were not statistically significant; 5. Statistically significant differences as to levels of prealbumin (Tab. 6), inorganic phosphorus (Tab. 7) and ascorbic acid (Tab. 8) between the study and control groups were found. In conclusion, conditions at the workplace should be improved, efforts to reduce exposure to physical and chemical risk factors should be intensified, and a healthy lifestyle should be promoted among industrial workers.

Description of Various Factors Contributing to Traffic Accidents in Youth and Measures Proposed to Alleviate Recurrence.

Traffic accidents are the leading cause of hospitalization in adolescence, with the 18-24-year-old age group accounting for 23% of deaths by traffic accidents. Recurrence rate is also high. One in four teenagers will have a relapse within the year following the first accident. Cognitive impairments known in adolescence could cause risky behaviors, defined as repetitive engagement in dangerous situations such as road accidents. Two categories of factors seem to be associated with traffic accidents: (1) factors specific to the traffic environment and (2) "human" factors, which seem to be the most influential. Moreover, the establishment of a stronger relation to high speed driving increases traffic accident risks and can also be intensified by sensation seeking. Other factors such as substance use (alcohol, drugs, and "binge drinking") are also identified as risk factors. Furthermore, cell phone use while driving and attention deficit disorder with or without hyperactivity also seem to be important risk factors for car accidents. The family environment strongly influences a young person's driving behavior. Some interventional driving strategies and preventive measures have reduced the risk of traffic accidents among young people, such as the graduated driver licensing program and advertising campaigns. So far, few therapeutic approaches have been implemented. Reason why, we decided to set up an innovative strategy consisting of a therapeutic postaccident group intervention, entitled the ECARR2 protocol, to prevent recurrence among adolescents and young adults identified at risk, taking into account the multiple risk factors.

This study sought to examine factors that are predictive of future developmental dyslexia among a group of 5-year-old Chinese children at risk for dyslexia, including 62 children with a sibling who had been previously diagnosed with dyslexia and 52 children who manifested clinical at-risk factors in aspects of language according to testing by paediatricians. The age-5 performances on various literacy and cognitive tasks, gender and group status (familial risk or language delayed) were used to predict developmental dyslexia 2 years later using logistic regression analysis. Results showed that greater risk of dyslexia was related to slower rapid automatized naming, lower scores on morphological awareness, Chinese character recognition and English letter naming, and gender (boys had more risk). Three logistic equations were generated for estimating individual risk of dyslexia. The strongest models were those that included all print-related variables (including speeded number naming, character recognition and letter identification) and gender, with about 70% accuracy or above. Early identification of those Chinese children at risk for dyslexia can facilitate better dyslexia risk management. Copyright © 2012 John Wiley & Sons, Ltd.

Summary Background and objectives South Asians (SAs) comprise 25% of all Canadian visible minorities. SAs constitute a group at high risk for cardiovascular disease in the general population, but the risk in SA kidney transplant recipients has never been studied. Design, setting, participants, & measurements In a cohort study of 864 kidney recipients transplanted from 1998 to 2007 and followed to June 2009, we identified risk factors including ethnicity associated with major cardiac events (MACEs, a composite of nonfatal myocardial infarction, coronary intervention, and cardiac death) within and beyond 3 months after transplant. Kaplan-Meier methodology and multivariate Cox regression analysis were used to determine risk factors for MACEs. Results There was no difference among SAs (n = 139), whites (n = 550), blacks (n = 65), or East Asians (n = 110) in baseline risk, including pre-existing cardiac disease. Post-transplant MACE rate in SAs was 4.4/100 patient-years compared with 1.31, 1.16, and 1.61/100 patient-years in whites, blacks, and East Asians, respectively (P < 0.0001 versus each). SA ethnicity independently predicted MACEs along with age, male gender, diabetes, systolic BP, and prior cardiac disease. SAs also experienced more MACEs within 3 months after transplant compared with whites (P < 0.0001), blacks (P = 0.04), and East Asians (P = 0.006). However, graft and patient survival was similar to other groups. Conclusions SA ethnicity is an independent risk factor for post-transplant cardiac events. Further study of this high-risk group is warranted. PMID:20884776
