    Outcome Predictors of Pneumonia in Elderly Patients: Importance of Functional Assessment

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 10 2004
    Olga H. Torres MD
    Objectives: To evaluate the outcome of elderly patients with community-acquired pneumonia (CAP) seen at an acute-care hospital, analyzing the importance of CAP severity, functional status, comorbidity, and frailty. Design: Prospective observational study. Setting: Emergency department and geriatric medical day hospital of a university teaching hospital. Participants: Ninety-nine patients aged 65 and older seen for CAP over a 6-month recruitment period. Measurements: Clinical data were used to calculate Pneumonia Severity Index (PSI), Barthel Index (BI), Charlson Comorbidity Index, and Hospital Admission Risk Profile (HARP). Patients were then assessed 15 days later to determine functional decline and 30 days and 18 months later for mortality and readmission. Multiple logistic regression was used to analyze outcomes. Results: Functional decline was observed in 23% of the 93 survivors. Within the 30-day period, case-fatality rate was 6% and readmission rate 11%; 18-month rates were 24% and 59%, respectively. Higher BI was a protective factor for 30-day and 18-month mortality (odds ratio (OR)=0.96, 95% confidence interval (CI)=0.94,0.98 and OR=0.97, 95% CI=0.95,0.99, respectively; P<.01), and PSI was the only predictor for functional decline (OR=1.03, 95% CI=1.01,1.05; P=.01). Indices did not predict readmission. Analyses were repeated for the 74 inpatients and indicated similar results except for 18-month mortality, which HARP predicted (OR=1.73; 95% CI=1.16,2.57; P<.01). Conclusion: Functional status was an independent predictor for short- and long-term mortality in hospitalized patients whereas CAP severity predicted functional decline. Severity indices for CAP should possibly thus be adjusted in the elderly population, taking functional status assessment into account. [source]


    Screening for local and regional cancer recurrence in patients curatively treated for laryngeal cancer: Definition of a high-risk group and estimation of the lead time

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 5 2007
    Savitri C. Ritoe MD
    Abstract Background. All patients treated for laryngeal cancer are offered the same follow-up schedule to detect asymptomatic locoregional recurrences. In this study, we evaluated the prognostic profile of patients for cancer recurrence and estimated the lead time. Methods. A cohort study was performed between 1990 and 1995. Cox proportional hazards model was used to analyze the prognostic factors. The effect of altering the follow-up for asymptomatic recurrence detection was determined after estimating the lead time. Results. The variables cT classification, smoking, and histologic grade proved to be prognostic factors. The risk of locoregional failure was 15% in the low-risk group versus 29% in the high-risk group. The estimated lead time was 2 to 4 weeks. Conclusion. Risk profiles for locoregional relapse were defined. Intensifying the follow-up schedule is not advisable because the lead time is very short. An excessively high number of routine visits would have to be performed to increase the detection rate for asymptomatic recurrences. © 2006 Wiley Periodicals, Inc. Head Neck, 2007 [source]


    Risk profiles for non-adherence to antipsychotic medications

    JOURNAL OF PSYCHIATRIC & MENTAL HEALTH NURSING, Issue 8 2008
    T. V. MCCANN rmn rgn phd ma ba dipnurs (lond) rnt rcnt
    Poor adherence to medications is common in individuals with schizophrenia, and can lead to relapse and re-hospitalization. This paper presents the findings of an Australian study of the factors affecting antipsychotic medication taking in individuals with schizophrenia. The Factors Influencing Neuroleptic Medication Taking Scale was used with a non-probability sample of mental health service users. Ethics approval was obtained from a university and a hospital ethics committee. Data were analysed using spss version 15. Most participants had insight into their illness and were aware of the stigma of mental illness. Around 70% experienced annoying side effects, while nearly half admitted alcohol consumption. About one-fifth admitted they had missed taking medications during the previous week. Significant others played a variable role in medication taking. Over 80% were satisfied with their relationships with health professionals, but were less satisfied with access to these professionals, especially psychiatrists. Logistic regression analysis showed that age, impact of medication side effects, and access to psychiatrists were independent predictors of medication omission. It is argued that medication taking is a complex issue, which needs to be taken into consideration in health professional training and measures to promote adherence. [source]


    Diagnostic Accuracy of the Gail Model in the Black Women's Health Study

    THE BREAST JOURNAL, Issue 4 2007
    Lucile L. Adams-Campbell PhD
    Abstract:, The Gail model is used to predict the risk of breast cancer in women of diverse race/ethnic groups for clinical trial protocols. However, this model has only been validated in US white women. Using a nested case-control study design, we evaluated the diagnostic accuracy of the original Gail model (GM) and that of the revised Gail model algorithm for blacks/African-Americans (GM-B) in the Black Women's Health Study (BWHS). Risk profiles were derived via a self reported questionnaire at the time of enrollment into the BWHS in 1995. Biennial questionnaires were obtained from the participants to determine the incident cases of breast cancer. The study of 725 breast cancer cases and 725 controls revealed that the 5-year risk of breast cancer based on the GM ranged from 0.2% to 15.4% among cases and 0.2% to 13.6% among the controls. Based on the GM-B, the 5-year risk of breast cancer ranged from 0.2% to 8.7% among cases and 0.2% to 7.2% among the controls. The sensitivities of the GM and GM-B model with the standard cutoff of 1.7% were 17.9% (95% CI: 15.9,19.9%) and 4.1% (95% CI: 3.0,5.2), respectively. Both the original and the modified version of the Gail model underestimate the risk of developing breast cancer in African-American women. More importantly, the modified Gail Model (GM-B) does a worse job at predicting the development of breast cancer for blacks than the original model (GM). [source]


    Current guidelines applicable for the approval of topically applied dermatological drugs in the EU

    FUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 5 2004
    Myrjam Dorothea Straube
    Abstract Dermatologicals as well as other medicinal products are submitted to the rules governing medicinal products in the European Union (EU) (Directive 2001/83/EC). With appreciation of the EU enlargement those regulatories deserve a recent consideration with special regard to the peculiarities of external dermatological therapy, recently passed novel and future guidelines. As regards the criteria for authorization of a medicinal product it is set out in Regulation (EEC) 2309/93 Article 11(1) that a marketing authorization shall be refused if it appears that the quality, the safety or efficacy of the medicinal product have not been adequately or sufficiently demonstrated by the applicant. Article 26(1) of Council Directive 2001/83/EC is worded a little differently but the criteria are the same irrespective of the procedure for the marketing authorization. For the final evaluation of the benefit/risk profile of a topically applied dermatological medicinal product not only the active agent but the whole galenic formulation as well has to be taken into account as the extent of penetration of the active compound might be influenced by changing the non-active substances. Furthermore the vehicle itself , independent of the active agent , influence the dermatological disorder, often in dependence on the stage of the dermatopathy. With special concern to safety/tolerability the (photo)toxic and (photo)allergic potential of the dermatological drug have to be taken into consideration too. In case of total body therapy in children the differing percutaneous resorption due to another body surface/body weight relation deserves special concern. The following review gives a survey of the current most important EU-guidelines for the evaluation of the benefit/risk profile of topically applied dermatological medicinal drugs and an outlook on further developments. As systemically applied dermatological medicinal products are assessed like other systemically applied drugs they are not treated in the following contribution. [source]


    Elevated C-reactive protein in Native Canadian children: an ominous early complication of childhood obesity

    DIABETES OBESITY & METABOLISM, Issue 5 2006
    R. Retnakaran
    Aim:, Subclinical inflammation has been proposed as a pathophysiologic mechanism linking obesity with vascular and metabolic disease. Native North American populations are experiencing high prevalence rates of both (i) childhood obesity and (ii) adult cardiovascular disease (CVD) and type 2 diabetes. Thus, we sought to determine whether subclinical inflammation is an early complication of obesity in Native children. Methods:, Serum concentrations of the inflammatory biomarker C-reactive protein (CRP) were assessed in a population-based, cross-sectional study of the Sandy Lake Oji-Cree community of Northern Ontario, Canada, involving 228 children aged 10,19 years (mean age 14.8). Results:, Median CRP in this population was 0.5 mg/l (interquartile range 0.18,1.79 mg/l). CRP levels were higher than age-matched reference data from the Third National Health and Nutrition Examination Survey (NHANES III). Importantly, fully 15.8% of the children of this community had CRP concentrations between 3 and 10 mg/l, a range that identifies adults at high risk of CVD. Moreover, increasing CRP concentration in this paediatric population was associated with an enhanced CV risk profile, consisting of increased adiposity, higher insulin resistance, worsening lipid profile (higher total cholesterol, triglycerides, low-density lipoprotein cholesterol, apolipoprotein B and total cholesterol : high-density-lipoprotein cholesterol ratio), increased leptin and decreased adiponectin. On multivariate analysis, waist circumference and interleukin-6 (IL-6) emerged as independent determinants of CRP concentration. Conclusion:, Subclinical inflammation is an early complication of childhood obesity in Native children and may foreshadow an increased burden of CVD and type 2 diabetes in the future. [source]


    Comparing risk profiles of individuals diagnosed with diabetes by OGTT and HbA1cThe Danish Inter99 study

    DIABETIC MEDICINE, Issue 8 2010
    R. Borg
    Diabet. Med. 27, 906,910 (2010) Abstract Aims, Glycated haemoglobin (HbA1c) has been proposed as an alternative to the oral glucose tolerance test for diagnosing diabetes. We compared the cardiovascular risk profile of individuals identified by these two alternative methods. Methods, We assessed the prevalence of cardiovascular risk factors in individuals with undiagnosed diabetes according to the World Health Organization classification or by the newly proposed HbA1c level , 6.5% among 6258 participants of the Danish Inter99 study. Receiver operating curve analysis assessed the ability of fasting: 2-h plasma glucose and HbA1c to distinguish between individuals at high and low risk of ischemic heart disease, predicted by the PRECARD program. Results, Prevalence of undiagnosed diabetes was 4.1% [95% confidence interval (CI) 3.7,4.7%] by the current oral glucose tolerance test definition, whereas 6.6% (95% CI 6.0,7.2%) had diabetes by HbA1c levels. HbA1c -defined individuals were relatively older with higher proportions of men, smokers, lipid abnormalities and macro-albuminuria, but they were leaner and had lower blood pressure. HbA1c was better than fasting- and 2-h plasma glucose at distinguishing between individuals of high and low predicted risk of ischaemic heart disease; however, the difference between HbA1c and fasting- and 2-h plasma glucose was not statistically significant. Conclusions, Compared with the current oral glucose tolerance test definition, more individuals were classified as having diabetes based on the HbA1c criteria. This group had as unfavourable a risk profile as those identified by the oral glucose tolerance test. [source]


    Effects of diabetes on plasma nitrotyrosine levels

    DIABETIC MEDICINE, Issue 6 2004
    X. L. Wang
    Abstract Background Oxidative stress plays a major role in disease processes such as atherosclerosis and diabetes. Peroxynitrite is a reaction product of nitric oxide (NO) and superoxide and a potent oxidant. The peroxynitrite-mediated tyrosine nitration, which forms nitrotyrosine (NT), is associated with several pathological conditions. Methods We measured plasma NT levels using the HPLC method in 40 Mexican Americans with diabetes, but not taking medications, and 40 age- and sex-matched euglycaemic controls. Results Plasma-free NT levels were not different between subjects with diabetes (11.0 ± 1.7 nmol/l, n = 40) and with non-diabetes (10.4 ± 1.5 nmol/l, n = 40). There was also no association with levels of fasting glucose (r = ,0.049, P = 0.663) or 2-h glucose (r = ,0.099, P = 0.390). However, females had significantly lower free NT level (7.6 ± 1.4 nmol/l, n = 40) than males (13.8 ± 1.7 nmol/l, n = 40, P = 0.005), which were not affected by age, smoking status, BMI and glucose levels. Conclusions In contrast to some earlier reports, our study shows that diabetes has no effect on plasma NT levels in Mexican Americans. We have also demonstrated lower free NT levels in females than males, which may partly explain the lower risk profile to vascular disease in women. [source]


    Heterogeneity of non-insulin-dependent diabetes expressed as variability in insulin sensitivity, ,-cell function and cardiovascular risk profile

    DIABETIC MEDICINE, Issue 1 2003
    K. I. Birkeland
    Abstract Aims The present study investigated the variability in insulin sensitivity and ,-cell function and their relationship to anti-glutamic acid decarboxylase (GAD) positivity and the metabolic syndrome in a group of patients with non-insulin-dependent diabetes mellitus (NIDDM). Methods Fifty-four subjects aged 59.5 ± 6.1 (mean ± sd) years with NIDDM for 7.9 ± 3.9 years referred to hospital due to poor glycaemic control, were investigated. Insulin sensitivity was determined by the euglycaemic hyperinsulinaemic glucose clamp technique as the glucose disposal rate relative to the insulin level obtained (GDRI), and also estimated with the homeostasis model assessment (HOMA-S). ,-cell function was measured by assaying the fasting and glucagon-stimulated C-peptide levels and with the HOMA-B. Results The insulin sensitivity varied 18-fold between subjects when estimated with the clamp and six-fold when estimated with HOMA-S, and was lower the more criteria for the metabolic syndrome present (P = 0.0001 by anova). The ,-cell function varied four-fold when measured as stimulated C-peptide, and eight-fold when estimated with the HOMA-B. The levels of fasting C-peptide and HOMA-B values tended to be lower in anti-GAD+ (n = 11) than in anti-GAD,subjects (P = 0.06 and P = 0.08, respectively). From previously published coronary risk charts, we estimated the 10-year risk of a coronary heart disease (CHD) event to be > 20% in 17 of 39 patients free from cardiovascular disease at the time of study, 16 of whom qualified for a diagnosis of the metabolic syndrome. Conclusions The wide variations in insulin sensitivity and ,-cell function found among subjects with NIDDM support the notion that the disorder is highly heterogeneous. Reduced insulin sensitivity was clearly related to the metabolic syndrome and an increased risk for CHD. [source]


    Risk Mapping and Key Risk Indicators in Operational Risk Management

    ECONOMIC NOTES, Issue 2 2005
    Sergio Scandizzo
    In this article I describe a methodology for the mapping of Operational Risk with the objective of identifying the risks inherent in the different steps of a business process, selecting a set of variables providing an estimate for the likelihood and the severity of operational risk (Key Risk Indicators , KRIs) and designing the most appropriate control activities. I then present two examples of how the methodology described can be applied to map risks and of how a set of relevant KRIs can be identified in the front office of a trading business and in the back office of a lending business. Finally, I discuss how the information conveyed by the KRIs can be organised and summarised in order to provide a comprehensive look at the risk profile of the various business lines. The structured presentation of KRIs covering the business processes of a bank is what we call an Operational Risk Scorecard. [source]


    Analysing Perceived Downside Risk: the Component Value-at-Risk Framework

    EUROPEAN FINANCIAL MANAGEMENT, Issue 4 2004
    Winfried G. Hallerbach
    G3; G32; G1; G14 Abstract Multinational companies face increasing risks arising from external risk factors, e.g. exchange rates, interest rates and commodity prices, which they have learned to hedge using derivatives. However, despite increasing disclosure requirements, a firm's net risk profile may not be transparent to shareholders. We develop the ,Component Value-at-Risk (VaR)' framework for companies to identify the multi-dimensional downside risk profile as perceived by shareholders. This framework allows for decomposing downside risk into components that are attributable to each of the underlying risk factors. The firm can compare this perceived VaR, including its composition and dynamics, to an internal VaR based on net exposures as it is known to the company. Any differences may lead to surprises at times of earnings announcements and thus constitute a litigation threat to the firm. It may reduce this information asymmetry through targeted communication efforts. [source]


    Risk management lessons from Long-Term Capital Management

    EUROPEAN FINANCIAL MANAGEMENT, Issue 3 2000
    Philippe Jorion
    The 1998 failure of Long-Term Capital Management (LTCM) is said to have nearly blown up the world's financial system. For such a near-catastrophic event, the finance profession has precious little information to draw from. By piecing together publicly available information, this paper draws risk management lessons from LTCM. LTCM's strategies are analysed in terms of the fund's Value at Risk (VAR) and the amount of capital necessary to support its risk profile. The paper shows that LTCM had severely underestimated its risk due to its reliance on short-term history and risk concentration. LTCM also provides a good example of risk management taken to the extreme. Using the same covariance matrix to measure risk and to optimize positions inevitably leads to biases in the measurement of risk. This approach also induces the strategy to take positions that appear to generate ,arbitrage' profits based on recent history but also represent bets on extreme events, like selling options. Overall, LTCM's strategy exploited the intrinsic weaknesses of its risk management system. [source]


    Haem oxygenase-1 genotype and cardiovascular adverse events in patients with peripheral artery disease

    EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 12 2005
    P. Dick
    Abstract Background, A functional GT dinucleotide length polymorphism in the haem oxygenase-1 (HO-1) gene promoter is thought to be involved in the pathogenesis of cardiovascular disease. Short (< 25) (GT)n repeats are suggested to facilitate enhanced HO-1 up-regulation in response to injury and confer potent anti-inflammatory and antioxidative effects. Materials and methods, We investigated the association between the HO-1 GT-polymorphism and cardiovascular outcome in 472 patients with advanced peripheral artery disease. Cardiovascular risk profile and DNA samples for determination of the HO-1 genotype (carrier vs. noncarrier of a short (GT)n repeat allele) were obtained at baseline, and patients were followed for median 21 months for the occurrence of coronary events (myocardial infarction, percutaneous coronary interventions and coronary artery bypass graft), cerebrovascular events (stroke or carotid revascularization) and all-cause mortality. Results, Coronary events occurred in 48 patients (9%), cerebrovascular events in 40 patients (9%) and 59 patients (13%) died. In total, 173 major adverse cardiovascular events (MACE) occurred in 133 patients (28%). Carriers of the short (GT)n repeat allele had a 0·46-fold reduced adjusted hazard ratio for coronary events (P = 0·016) as compared to noncarriers. No significant difference was found for cerebrovascular events, mortality and overall MACE. Conclusion, Apparently, the HO-1 genotype exerts potentially protective effects against coronary adverse events in patients with peripheral artery disease. Homozygous and heterozygous carriers of < 25 (GT)n repeats had lower rates of myocardial infarction, percutaneous coronary interventions and coronary bypass operations compared to patients with longer (GT)n repeats.

    Relevance of post-methionine homocysteine and lipoprotein (a) in evaluating the cardiovascular risk in young CAD patients

    EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 1 2005
    R. Marcucci
    Abstract Background, Aims of our study were to evaluate the prevalence of high lipoprotein (a) [Lp(a)] and homocysteine levels , both in the fasting state (FHcy) and post-methionine (PMHcy) , in young coronary artery disease (CAD) patients, and to investigate the role of genetic and environmental factors for hyperhomocysteinaemia. Materials and methods, We studied 140 patients with angiographically documented CAD (24 women , 55 years and 116 men , 50 years) and 140 healthy subjects as controls. Results, Both FHcy [13·2 (5·4,45·8) vs. 9·0 (5·1,24) µmol L,1); P < 0·0001] and PMHcy [(39·4 (9·0,66·4) vs. 25·2 (16·4,33·9); P < 0·0001] were significantly higher in patients than in controls. Lp(a) levels were significantly higher in patients than in controls (200 (3,1486) mg L,1 vs. 97 (10,412) mg L,1; P < 0·0001). At the multivariate analysis, adjusted for the classical cardiovascular risk factors and creatinine levels, the OR (95% CI) for CAD at young age significantly increased in the fourth quartile of the distribution of FHcy, PMHcy and Lp(a) levels [FHcy: 14·9 (4·1,58), P < 0·0001; PMHcy: 19·2 (4·0,86·3); P < 0·0001; Lp(a): 19·6 (4·7,78·6): < 0·0001]. Vitamin deficiencies were detected in 28/140 (20%) patients. The prevalence of the homozygous C677T (+/+) methylenetetrahydrofolatereductase genotype was higher, but not significantly different, in patients (22·8%) than in controls (18·6%). The allele frequency of the 844ins68 insertion variant in the cystathionine beta-synthase gene was 0·08 in the control group and 0·06 in the patient group. Conclusions, Results of the present study indicate the usefulness of including fasting and post-methionine Hcy, and Lp(a) determination in the diagnostic panels of young CAD patients, in order to obtain a better assessment of their cardiovascular risk profile.

    Acute ischemic stroke and transient ischemic attack in the very old , risk factor profile and stroke subtype between patients older than 80 years and patients aged less than 80 years

    EUROPEAN JOURNAL OF NEUROLOGY, Issue 8 2007
    J. I. Rojas
    Old age groups have different risk profile and stroke features compared to younger groups. Our aim was to examine the risk factor profile and stroke subtype in patients older than 80 years with ischemic stroke. Data of 535 patients with ischemic stroke or transient ischemic attack (TIA) were prospectively recorded. Cardiovascular risk factors and stroke subtype in individuals aged 80 years or older were compared with patients under 80. Of 535 patients a total of 179 were over 80 years (33.5%). The mean age was 84.4 ± 4.4 years (61.8%; 111 women). The most common risk factors included hypertension (82.7%) and hyperlipidemia (40.2%). Lacunar stroke was the most frequent subtype of stroke (41.7%). When the groups were compared, we observed the following risk factors more frequently in the group older than 80: female patients (P = <0.001), hypertension (OR = 1.62), atrial fibrillation (OR = 2.64); whereas diabetes (OR = 0.54), hyperlipidemia (OR = 0.57), smoking (OR = 0.17) and obesity (OR = 0.58) were more frequent in the group younger than 80. In the old group we found a high incidence of ischemic stroke in women. We also found a higher frequency of hypertension and atrial fibrillation. The available and future epidemiological data will provide a better knowledge about the effect of typical risk factors in old people. [source]


    Comment on: Tattooing of skin results in transportation and light-induced decomposition of tattoo pigments

    EXPERIMENTAL DERMATOLOGY, Issue 1 2010
    Gregor B. E. Jemec
    Abstract:, Decorative tattoos have become a common feature of many societies. Their popularity appears mainly driven by fashion, and scant attention has been paid to any associated risk. The risks can be associated either with the tattooees' proclivity for risk taking in general, or with the substances used in the tattoos. It is well established that tattoo pigments wander widely in the body after they have been injected, and research now suggests that azo pigments may become mutagenic after exposure to either natural light or laser light. This may not only affect the risk profile of tattoos themselves, but also tattoo removal using lasers. [source]


    The intrahepatic immune response during chronic hepatitis B infection can be monitored by the fine-needle aspiration biopsy technique

    FEMS IMMUNOLOGY & MEDICAL MICROBIOLOGY, Issue 1 2003
    Thjon J Tang
    Abstract Frequent analysis of the intrahepatic cellular immune response during chronic hepatitis B infection is not feasible with the liver tissue biopsy technique, due to its risk profile and patient discomfort. We investigated whether the relatively safe and patient-friendly cytological fine-needle aspiration biopsy (FNAB) technique is suited for this purpose. FNABs taken during hepatitis flares in three chronic hepatitis B patients treated with interferon-,, showed significant increments of CD8+ -lymphocytes compared with the FNABs taken before and after the flares. No increments were observed in peripheral blood. The increments of intrahepatic CD8+ lymphocytes detected by the FNAB were related to anti-viral immune reactivity, since they coincided with significant serum hepatitis B virus DNA level reductions and in two of three patients with HBeAg seroconversion. In conclusion, the FNAB technique is suited to investigate the intrahepatic immune response during chronic hepatitis B infection on a frequent basis. [source]


    Small,Scale Entrepreneurship and Access to Capital in Peripheral Locations: An Empirical Analysis

    GROWTH AND CHANGE, Issue 2 2002
    Daniel Felsenstein
    This paper presents an analysis of a public assistance program for small,scale entrepreneurship in peripheral areas. Public assistance compensates for market inefficiencies where the decision rules of financial institutions discriminate against otherwise viable small firms in capital markets. Lending institutions perceive high risk in providing debt capital when little information is present. Using empirical data from Israel, the determinants of this risk are estimated and the role of location in creating this information asymmetry is stressed. These results empirically establish that (1) location matters in determining the risk profile of the firm, (2) locationally targeted programs can reduce the information asymmetries that make peripheral firms unattractive to lenders, and (3) these programs can also generate positive welfare effects. Finally, there is speculation on the potential role of ICT (information and communications technology) in increasing the visibility of small firms in remote locations and creating a more symmetrical flow of information.

    Risk Segmentation Related to the Offering of a Consumer-Directed Health Plan: A Case Study of Humana Inc.

    HEALTH SERVICES RESEARCH, Issue 4p2 2004
    Laura A. Tollen
    Objective. To determine whether the offering of a consumer-directed health plan (CDHP) is likely to cause risk segmentation in an employer group. Study Setting and Data Source. The study population comprises the approximately 10,000 people (employees and dependents) enrolled as members of the employee health benefit program of Humana Inc. at its headquarters in Louisville, Kentucky, during the benefit years starting July 1, 2000, and July 1, 2001. This analysis is based on primary collection of claims, enrollment, and employment data for those employees and dependents. Study Design. This is a case study of the experience of a single employer in offering two consumer-directed health plan options ("Coverage First 1" and "Coverage First 2") to its employees. We assessed the risk profile of those choosing the Coverage First plans and those remaining in more traditional health maintenance organization (HMO) and preferred provider organization (PPO) coverage. Risk was measured using prior claims (in dollars per member per month), prior utilization (admissions/1,000; average length of stay; prescriptions/1,000; physician office visit services/1,000), a pharmacy-based risk assessment tool (developed by Ingenix), and demographics. Data Collection/Extraction Methods. Complete claims and administrative data were provided by Humana Inc. for the two-year study period. Unique identifiers enabled us to track subscribers' individual enrollment and utilization over this period. Principal Findings. Based on demographic data alone, there did not appear to be a difference in the risk profiles of those choosing versus not choosing Coverage First. However, based on prior claims and prior use data, it appeared that those who chose Coverage First were healthier than those electing to remain in more traditional coverage. For each of five services, prior-year usage by people who subsequently enrolled in Coverage First 1 (CF1) was below 60 percent of the average for the whole group. Hospital and maternity admissions per thousand were less than 30 percent of the overall average; length of stay per hospital admission, physician office services per thousand, and prescriptions per thousand were all between 50 and 60 percent of the overall average. Coverage First 2 (CF2) subscribers' prior use of services was somewhat higher than CF1 subscribers', but it was still below average in every category. As with prior use, prior claims data indicated that Coverage First subscribers were healthier than average, with prior total claims less than 50 percent of average. Conclusions. In this case, the offering of high-deductible or consumer-directed health plan options alongside more traditional options caused risk segmentation within an employer group. The extent to which these findings are applicable to other cases will depend on many factors, including the employer premium contribution policies and employees' perception of the value of the various plan options. Further research is needed to determine whether risk segmentation will worsen in future years for this employer and if so, whether it will cause premiums for more traditional health plans to increase.

    Case Report: Atheroembolic renal disease in a 72-year-old patient through coronary intervention after myocardial infarction

    HEMODIALYSIS INTERNATIONAL, Issue 4 2008
    Anna Laura HERZOG
    Abstract Cholesterol embolization or atheroembolic renal disease (AERD) is an often underdiagnosed issue in patients featuring a prevalent risk profile. It is a multisystemic disease with progressive renal insufficiency due to foreign body reaction of cholesterol crystals flushed into a small vessel system of the kidneys from the arteriosclerotic plaques. The most common setting in which it occurs is iatrogenic after vascular catheterization and less frequent spontaneously. Typical clinical symptoms are delayed impairment of renal function, cutaneous manifestations such as livedo reticularis or purple toes with persistingly palpable arterial pulse, myalgia, systemic symptoms such as weight loss and fever, and abdominal and neurological symptoms. Diagnosis is generally made by clinical appearance, risk profile, and interval of time from intervention; a definitive diagnosis can only be made by renal biopsy. Even though the exact incidence is not known because most patients do not undergo biopsy due to older age, comorbidity, and other explanations for loss of renal function, it is estimated to be 4% after vascular intervention. Patient and renal outcome is dependent on comorbidity, risk profile, and preexisting chronic kidney disease (CKD). About 30% of patients are estimated to require maintenance dialysis and these patients have a high risk of death within 24 months after the first renal replacement therapy. Prognosis is also influenced by severity. The case reported is a 72-year-old male patient with preexisting CKD stage 3 undergoing percutaneous coronary intervention after myocardial infarction and consecutive AERD with typical clinical appearance 6 weeks after the event.

    Low-risk factor profile, estrogen levels, and breast cancer risk among postmenopausal women

    INTERNATIONAL JOURNAL OF CANCER, Issue 8 2009

    Abstract Obesity, alcohol consumption, physical inactivity and postmenopausal hormone use are known modifiable risk factors for breast cancer. We aim to measure incidence rates of breast cancer for women with favorable levels on all 4 risk factors (BMI , 30 kg/m2, alcohol <1 drink/week, physically active and no current hormone use) and to evaluate their associations with estrogen. The 5,054 postmenopausal women in the Copenhagen City Heart Study were asked about risk factors at baseline in 1981,3 and were followed until 2002 in the Danish Cancer Registry, with <0.1% loss to follow-up. Estradiol was measured in a subset of 1,042 women. During follow-up, 263 women developed breast cancer. Twenty-six percent of the women had a favourable risk factor profile, and their breast cancer rates were markedly lower (154 per 100,000 years) than women with 3+ risk factors (460 per 100,000 years). One, two and three risk factors were associated with hazard ratios of 1.38 (95% CI: 0.99; 1.92), 1.84 (1.26; 2.67) and 2.79 (1.59; 4.88) compared to women with a favourable profile. Each of the risk factors was associated with estrogen. In conclusion, the risk of breast cancer was markedly lower for women with a favourable risk profile than for other women and lower estrogen levels is a possible explanation. © 2008 Wiley-Liss, Inc.

    Cardiovascular risk evaluation and antiretroviral therapy effects in an HIV cohort: implications for clinical management: the CREATE 1 study

    INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 9 2010
    M. Aboud
    Summary Aims:, The aim of this study is to determine the cardiovascular disease (CVD) risk profile of a large UK HIV cohort and how highly active antiretroviral therapy (HAART) affects this. Methods:, It is a cross-sectional study within a large inner city hospital and neighbouring district hospital. A total of 1021 HIV positive outpatients representative of the complete cohort and 990 who had no previous CVD were included in CVD risk analysis. We recorded demographics, HAART history and CVD risk factors. CVD and coronary heart disease (CHD) risks were calculated using the Framingham (1991) algorithm adjusted for family history. Results:, The non-CVD cohort (n = 990) was 74% men, 51% Caucasian and 73.1% were on HAART. Mean age was 41 ± 9 years, systolic blood pressure 120 ± 14 mmHg, total cholesterol 4.70 ± 1.05mmol/l, high-density lipoprotein-C 1.32 ± 0.48 mmol/l and 37% smoked. Median CVD risk was 4 (0,56) % in men and 1.4 (0,37) % in women; CHD risks were 3.5 (0,36) % and 0.6 (0,16) %. CVD risk was > 20% in 6% of men and 1% of women and > 10% in 12% of men and 4% of women. CVD risk was higher in Caucasians than other ethnicities; the risk factor contributing most was raised cholesterol. For patients on their first HAART, increased CHD risk (26.2% vs. 6.5%; odds ratio 4.03, p < 0.001) was strongly related to the duration of therapy. Conclusions:, Modifiable risk factors, especially cholesterol, and also duration of HAART, were key determinants of CVD risk. Discussion:, Regular CHD and/or CVD risk assessment should be performed on patients with HIV, especially during HAART therapy. The effect of different HAART regimens on CHD risk should be considered when selecting therapy. [source]


    Effectiveness of general practice nurse interventions in cardiac risk factor reduction among adults

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 3 2007
    Elizabeth Halcomb RN BN(Hons) Grad Cert.
    Abstract Background, Cardiovascular disease is the leading cause of death for adults in Australia. In recent years there has been a shift in health service delivery from institutional to community-based care for chronic conditions, including cardiovascular disease. The general practice setting is seen to offer greater flexibility, higher levels of efficiency and more client focused healthcare delivery than is possible in the acute care sector. It has been suggested that practice nurses represent a useful adjunct to current models of cardiovascular disease management. To date, significant descriptive research has been conducted exploring the demographics, roles, educational needs and issues facing practice nurses. However, there is a need to evaluate the effectiveness of practice nurse interventions in terms of patient outcomes, clinician satisfaction and cost-effectiveness. Objectives, This review seeks to present the best available evidence regarding the efficacy of general practice nurse interventions for cardiac risk factor reduction in healthy adults, as well as those with established cardiovascular disease or known cardiac risk factors. Search Strategy, A systematic literature search was performed using Medline (1966 , 2005), CINAHL (1982 ,2005), Cochrane Controlled Trials Register (Issue 4, 2005) and the Joanna Briggs Institute Evidence Library. In addition, the reference lists of retrieved papers, conference proceedings and the Internet, were scrutinised for additional trials. Selection Criteria, This review considered any English language randomised trials that investigated interventions conducted by the practice nurse for cardiovascular disease management or reduction of cardiac risk factors. Interventions conducted by specialist cardiac nurses in general practice were excluded. Outcomes measured included blood pressure, smoking cessation, total cholesterol, exercise, body weight/body mass index and cost-effectiveness. Results, Eighteen trials, reported in 33 papers, were included in the review. Ten trials investigated multifaceted interventions, while the remaining eight trials reported targeted interventions. Of the trials that reported multifaceted interventions, three trials investigated risk reduction in those with established cardiovascular disease, four trials focused on those with known cardiovascular disease risk factors and three trials included the general community. The eight trials which examined the efficacy of targeted interventions focused upon dietary intake (two trials), smoking cessation (three trials), weight reduction (one trial) and physical activity (two trials). The effect of both the multifaceted and targeted interventions on patient outcomes was variable. However, both the multifaceted and targeted interventions demonstrated similar outcome trends for specific variables. Improvements were demonstrated by most studies in blood pressure, cholesterol level, dietary intake and physical activity. The variation in outcome measures and contradictory findings between some studies makes it difficult to draw definitive conclusions. Conclusions, While interventions to reduce cardiovascular disease risk factors have produced variable results, they offer significant potential to assist patients in modifying their personal risk profile and should be developed. The public health importance of these changes is dependant upon the sustainability of the change and its effect on the health outcomes of these individuals. Further well-designed research is required to establish the effectiveness of practice nurse interventions for cardiovascular disease management and risk factor reduction in terms of patient outcomes and cost-effectiveness.

    Risk assessment and management: A community forensic mental health practice model

    INTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 4 2002
    Teresa Kelly
    ABSTRACT: In Victoria, the Crimes (Mental Impairment and Unfitness to be Tried) Act (1997) reformed legal practice in relation to the detention, management and release of persons found by a court to be not guilty on the grounds of insanity or unfit to be tried. This Act provides a legal structure for such ,forensic patients' to move from secure inpatient facilities into the community. This new legislative landscape has generated challenges for all stakeholders and has provided the impetus for the development of a risk assessment and management model. The key components of the model are the risk profile, assessment and management plan. The discussion comprises theory, legislation, practice implications and limitations of the model. Practice implications concern the provision of objective tools, which identify risk and document strategic interventions to support clinical management. Some of the practice limitations include the model's applicability to risk assessment and management and its dependence on a mercurial multi-service interface in after-hours crisis situations. In addition to this, the paper articulates human limitations implicit in the therapeutic relationship that necessarily underpins the model. The paper concludes with an exploration of the importance of evaluative processes as well as the need for formal support and education for clinicians. [source]


    Risk Factors for Potentially Harmful Informal Caregiver Behavior

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 2 2005
    Scott R. Beach PhD
    Objectives: Caring for a sick or disabled relative has been linked to compromised caregiver health, and risk factors for negative caregiver outcomes have been studied extensively, but little attention has been given to care recipient and caregiver health as risk factors for potentially harmful behavior by informal caregivers. This article explores such risk factors. Design: Structured interviews from baseline assessment of the Family Relationships in Late Life Study. Setting: Three U.S. communities. Participants: Referred, volunteer sample of 265 caregiver/care recipient dyads. Caregivers were primarily responsible for care of an impaired, community-residing family member aged 60 and older and providing help with at least one activity of daily living (ADL) or two instrumental activities of daily living (IADLs). Measurements: Self-reported care recipient demographics, cognitive status, need for care, and self-rated health; self-reported caregiver demographics, cognitive status, amount of care provided, self-rated health, physical symptoms, and depression. Care recipient reports of potentially harmful caregiver behavior, including screaming and yelling, insulting or swearing, threatening to send to a nursing home, and withholding food, were the main outcome variable. Results: The following were significant risk factors for potentially harmful caregiver behavior: greater care recipient ADL/IADL needs (odds ratio (OR)=1.12, 95% confidence interval (CI)=1.03,1.22), spouse caregivers (vs others; OR=8.00, 95% CI=1.71,37.47), greater caregiver cognitive impairment (OR=1.20, 95% CI=1.04,1.38), more caregiver physical symptoms (OR=1.07, 95% CI=1.01,1.13), and caregivers at risk for clinical depression (OR=3.47, 95% CI=1.58,7.62). Conclusion: Potentially harmful caregiver behavior is more likely in spouse caregiving situations and when care recipients have greater needs for care and caregivers are more cognitively impaired, have more physical symptoms, and are at risk for clinical depression. This risk profile is similar to that for negative caregiver outcomes. [source]


    Uric Acid as a Marker for Renal Dysfunction in Hypertensive Women on Diuretic and Nondiuretic Therapy

    JOURNAL OF CLINICAL HYPERTENSION, Issue 5 2009
    Rodolfo.
    Hyperuricemia is a common finding in hypertensive patients, especially among those who are on diuretic therapy. However, its clinical relevance regarding cardiovascular and chronic kidney disease (CKD) has not clearly been established. The authors assessed whether, in a population of 385 hypertensive women categorized according to diuretic therapy, the stratification in quartiles by uric acid levels would identify a gradient of changes in renal function and in risk factors for cardiovascular disease. The following were evaluated: serum uric acid, glycemia, total and fractional cholesterol, triglycerides, apolipoprotein (Apo) B, Apo A-I, and C-reactive protein. Renal function was assessed by serum creatinine, albuminuria, and estimated glomerular filtration rate (eGFR) by the Modification of Diet in Renal Disease equation, whereas cardiovascular risk was estimated through the Framingham score. A total of 246 women were on diuretic therapy; 139 were taking other antihypertensive medications. There was a reduction in eGFR parallel to the increase in uric acid levels, regardless of diuretic use and without a concomitant increase in albuminuria. In both groups, higher uric acid levels translated into an increase in metabolic syndrome components, in markers of insulin resistance, triglyceride/high-density lipoprotein levels, and Apo B/Apo A-I ratios, as well as in Framingham scores. Hyperuricemia was associated with an increase in inflammatory markers only in patients on diuretic therapy. In a binary logistic regression, hyperuricemia (uric acid >6.0 mg/dL) was independently associated with CKD (eGFR <60 mL/min/1.73 m²) (odds ratio, 2.63; 95% confidence interval, 1.61,4.3; P<.001). In hypertensive women, the presence of hyperuricemia indicated a substantial degree of kidney dysfunction as well as a greater cardiovascular risk profile. [source]


    Comparison of Commonly Used Assays for the Detection of Microalbuminuria

    JOURNAL OF CLINICAL HYPERTENSION, Issue 2004
    Douglas E. Busby MD
    There are a variety of methods for assessing urinary albumin excretion, extending from the very low-range microalbuminuria to higher ranges extending into macroalbuminuria or proteinuria. The recommendation for the initial screening of a new patient is to use a urine dipstick to assess for microalbuminuria. If positive, a spot urine for albumin:creatinine should be measured and reassessed annually. All patients with kidney disease, diabetes, or hypertension and metabolic syndrome should be screened for albuminuria. New methodologies using high-performance liquid chromatography are much more sensitive and specific when compared with older methods of detection and may prove very useful for earlier identification of high-risk patients. This is important since studies have shown that albuminuria levels below the microalbuminuria range, determined by conventional methodologies in uncomplicated essential hypertensive men, are associated with an adverse cardiovascular and metabolic risk profile. High performance liquid chromatography methodology, in contrast to older studies, detects all intact albumin and enables clinicians to assess disease severity and monitor therapeutic effectiveness with confidence in the accuracy of the microalbuminuria data reported to them.

    Risk factors of Hong Kong Chinese patients with coronary heart disease

    JOURNAL OF CLINICAL NURSING, Issue 7 2007
    Sek Ying Chair RN
    Aims and objectives., The aims of the study were to describe the level of modifiable coronary risk factors and to explore the relationships among these risk factors in patients with coronary heart disease. Background., Appropriate patient education and therapies for coronary risk reduction will prevent recurrent cardiac events and progression of coronary heart disease. Therefore, having knowledge of the risk profile of these patients is essential so that appropriate contents and focus of patient educations can be developed. Methods., Coronary heart disease patients admitted for cardiac catheterization at the two studied hospitals in Hong Kong were recruited for this study. Demographic date and risk factors of blood pressure, smoking status, body mass index, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and exercise level were collected from subjects as well as from medical records for analysis. Results., The body mass index was significantly different among non-smoker, ex-smoker and smoker (p = 0·027). Non-smokers had the highest body mass index but smokers had the lowest body mass index among the three groups in this study. Physical inactivity, overweight and hypercholesterolaemia were the risk factors seen in about 50% of the studied subjects. Body mass index correlated positively with systolic blood pressure but negatively correlated with high-density lipoprotein cholesterol and hour of exercise. Conclusions., Heavier subjects had a higher systolic blood pressure but a lower level of high-density lipoprotein cholesterol. Heavier subjects also exercised less. The study results provided additional information on the database of the risk profile among Hong Kong cardiac patients. Relevance to clinical practice., Hypertension, obesity, physical inactivity, abnormal serum lipid levels and smoking are the modifiable risk factors for coronary heart diseases. As physical inactivity, overweight and hypercholesterolaemia were found in half of the studied subjects, the importance of risk factors control should be addressed to this group of patients. Nurses should be aware of their educator role to provide appropriate education to coronary heart disease patients with the focus on reducing and controlling of cardiac risk factors, which has been shown to be effective in reducing the progress of disease.

    Matuliene G, Studer R, Lang NP, Schmidlin K, Pjetursson BE, Salvi GE, Brägger U, Zwahlen M. Significance of Periodontal Risk Assessment on the recurrence of periodontitis and tooth loss. J Clin Periodontol 2010; 37: 191,199. doi: 10.1111/j.1600-051X.2009.01508.x. Abstract Aim: To investigate the association of the Periodontal Risk Assessment (PRA) model categories with periodontitis recurrence and tooth loss during supportive periodontal therapy (SPT) and to explore the role of patient compliance. Material and Methods: In a retrospective cohort, PRA was performed for 160 patients after active periodontal therapy (APT) and after 9.5 ± 4.5 years of SPT. The recurrence of periodontitis and tooth loss were analysed according to the patient's risk profile (low, moderate or high) after APT and compliance with SPT. The association of risk factors with tooth loss and recurrence of periodontitis was investigated using logistic regression analysis. Results: In 18.2% of patients with a low-risk profile, in 42.2% of patients with a moderate-risk profile and in 49.2% of patients with a high-risk profile after APT, periodontitis recurred. During SPT, 1.61 ± 2.8 teeth/patient were lost. High-risk profile patients lost significantly more teeth (2.59 ± 3.9) than patients with moderate- (1.02 ± 1.8) or low-risk profiles (1.18 ± 1.9) (Kruskal,Wallis test, p=0.0229). Patients with erratic compliance lost significantly (Kruskal,Wallis test, p=0.0067) more teeth (3.11 ± 4.5) than patients compliant with SPT (1.07 ± 1.6). Conclusions: In multivariate logistic regression analysis, a high-risk patient profile according to the PRA model at the end of APT was associated with recurrence of periodontitis. Another significant factor for recurrence of periodontitis was an SPT duration of more than 10 years. [source]

    Abstract. Apeland T, Mansoor MA, Seljeflot I, Brønstad I, Gøransson L, Strandjord RE (Rogaland Central Hospital, Stavanger; and Ullevål University Hospital, Oslo; Norway). Homocysteine, malondialdehyde and endothelial markers in dialysis patients during low-dose folinic acid therapy. J Intern Med 2002; 252: 456,464. Objectives. Haemodialysis patients have elevated levels of the atherogenic amino acid homocysteine. We wanted to assess the effects of small doses of intravenous folinic acid (the active form of folic acid) on some biochemical risk factors of cardiovascular disease. Design. Longitudinal and open intervention study. Setting. Two dialysis units in the County of Rogaland. Subjects. All patients on maintenance haemodialysis were invited, and 32 of 35 patients gave their informed consent. Interventions. After each dialysis session, the patients were given 1.0 mg of folinic acid intravenously thrice a week for a period of 3 months. Prior to and during the study, all patients were on maintenance supplementation with small doses of vitamins B1, B2, B3, B5, B6 and B12. Main outcome measures. Changes in the levels of (i) plasma total homocysteine (p-tHcy) and folate, (ii) circulating endothelium related proteins , markers of endothelial activation and (iii) serum malondialdehyde (S-MDA) , a marker of oxidative stress and lipid peroxidation. Results. The p-tHcy levels were reduced by 37% (P < 0.0001), whilst the serum and erythrocyte folate levels increased by 95 and 104%, respectively (P < 0.0001 for both). The circulating levels of endothelium related cellular adhesion molecules and haemostatic factors remained high and unchanged, except the thrombomodulin (TM) levels increased (P = 0.0004). The high levels of S-MDA were reduced by 26% (P = 0.003). Conclusions. Low doses of folinic acid given intravenously to dialysis patients reduced their levels of p-tHcy and S-MDA and thus improved their cardiovascular risk profile. The concurrent increment in TM levels was unexpected and of unknown clinical significance. [source]
