Targeted Interventions (targeted + intervention)
Selected AbstractsExternal cause-specific summaries of occupational fatal injuries.AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 3 2003Part I: An analysis of rates Abstract Background Industries and occupations vary with respect to the incidence of fatal injuries and their causes. Methods Fatalities from the National Traumatic Occupational Fatality database (years 1983,1994) serve as the basis for examining external cause of death code specific rates. Industries and occupations are compared with respect to rate and frequency of fatal injuries. In addition, external causes of injury (E-codes) are examined across all industries and occupations as well as within industries and occupations to evaluate which events would be identified by frequency ordered comparisons versus injury rate ordered comparisons. Results Machinery, electric current, homicide, falls, and transportation-related events are identified by high frequency and rate of occurrence. Conclusions The external cause categories of homicide, machinery-related, motor-vehicle-related, electric current, and falls, account for over one-half of all occupational fatal injuries. Targeted interventions in homicide may be especially warranted in sales and service occupations and in the retail trade and services industries. In addition, younger workers might be targeted for special interventions designed to identify hazardous practices, procedures, and solutions to reduce fatalities associated with electrocution or falls from buildings.

Doubeni MD Abstract BACKGROUND. Despite declining death rates from colorectal cancer (CRC), racial disparities have continued to increase. In this study, the authors examined disparities in a racially diverse group of insured patients. METHODS. This study was conducted among patients who were diagnosed with CRC from 1993 to 1998, when they were enrolled in integrated healthcare systems. Patients were identified from tumor registries and were linked to information in administrative databases. The sample was restricted to non-Hispanic whites (n = 10,585), non-Hispanic blacks (n = 1479), Hispanics (n = 985), and Asians/Pacific Islanders (n = 909). Differences in tumor stage and survival were analyzed by using polytomous and Cox regression models, respectively. RESULTS. In multivariable regression analyses, blacks were more likely than whites to have distant or unstaged tumors. In Cox models that were adjusted for nonmutable factors, blacks had a higher risk of death from CRC (hazard ratio [HR], 1.17; 95% confidence interval [95% CI], 1.06,1.30). Hispanics had a risk of death similar to whites (HR, 1.04; 95% CI, 0.92,1.18), whereas Asians/Pacific Islanders had a lower risk of death from CRC (HR, 0.89; 95% CI, 0.78,1.02). Adjustment for tumor stage decreased the HR to 1.11 for blacks, and the addition of receipt of surgical therapy to the model decreased the HR further to 1.06. The HR among Hispanics and Asians/Pacific Islanders was stable to adjustment for tumor stage and surgical therapy. CONCLUSIONS. The relation between race and survival from CRC was complex and appeared to be related to differences in tumor stage and therapy received, even in insured populations. Targeted interventions to improve the use of effective screening and treatment among vulnerable populations may be needed to eliminate disparities in CRC.

Little data are currently available on the transitions to substance use disorders (SUDs) across the spectrum of legal and illegal drugs taking into account gender differences. It is the aim of this paper to describe the high density incidence and transition periods of SU and SUD for alcohol, nicotine, cannabis and other illicit drugs for young males and females. Methods: A sample of (N = 3021) community subjects aged 14,24 at baseline were followed-up prospectively over 10-years. SU and SUD were assessed using the DSM-IV/M-CIDI. Results: Ages 10,16 are the high risk period for first alcohol and nicotine use (up to 38% of subjects start before age 14). Onset of illegal SU occurs later. Substantial proportions of transitions to regular SU and SUD occur in the first three years after SU onset. Only few gender differences were found for time patterns of SU/SUD incidence and transition. Conclusion: Except for alcohol the time windows for targeted intervention to prevent progression to malignant patterns in adolescence are critically small, leaving little time for targeted intervention to prevent transition. The fast transitions to abuse and dependence in adolescence may be indicative for the increased vulnerability to substance effects in this time period. Basic research on the determinants of transitions should thus target this period in adolescence. Copyright © 2008 John Wiley & Sons, Ltd.

NØRRELUND Abstract. Objective., It is well known that chronic heart failure (CHF) is associated with insulin resistance and cachexia, but little is known about the underlying substrate metabolism. The present study was undertaken to identify disturbances of basal glucose, lipid and protein metabolism. Design., We studied eight nondiabetic patients with CHF (ejection fraction 30 ± 4%) and eight healthy controls. Protein metabolism (whole body and regional muscle fluxes) and total glucose turnover were isotopically assayed. Substrate oxidation were obtained by indirect calorimetry. The metabolic response to exercise was studied by bicycle ergometry exercise. Results., Our data confirm that CHF patients have a decreased lean body mass. CHF patients are characterised by (i) decreased glucose oxidation [glucose oxidation (mg kg,1 min,1): 1.25 ± 0.09 (patients) vs. 1.55 ± 0.09 (controls), P < 0.01] and muscle glucose uptake [a , v diffglucose (,mol L,1): ,10 ± 25 (patients) vs. 70 ± 22 (controls), P < 0.01], (ii) elevated levels of free fatty acids (FFA) [FFA (mmol L,1): 0.72 ± 0.05 (patients) vs. 0.48 ± 0.03 (controls), P < 0.01] and 3-hydroxybutyrate and signs of elevated fat oxidation and muscle fat utilization [a , v diffFFA (mmol L,1): 0.12 ± 0.02 (patients) vs. 0.05 ± 0.01 (controls), P < 0.05] and (iii) elevated protein turnover and protein breakdown [phenylalanine flux (,mol kg,1 h,1): 36.4 ± 1.5 (patients) vs. 29.6 ± 1.3 (controls), P < 0.01]. Patients had high circulating levels of noradrenaline, glucagon, and adiponectin, and low levels of ghrelin. We failed to observe any differences in metabolic responses between controls and patients during short-term exercise. Conclusions., In the basal fasting state patients with CHF are characterized by several metabolic abnormalities which may contribute to CHF pathophysiology and may provide a basis for targeted intervention. [source] Optimising the policy cost of market stabilisation: Which commodity matters most in Ethiopia?JOURNAL OF INTERNATIONAL DEVELOPMENT, Issue 3 2009Kindie Getnet Abstract Unprecedented food crop price spikes in recent years prompted the Ethiopian government to impose grain export ban and to distribute grain stocks as price stabilization strategies. Successful price stabilization and size of public spending for such programs depend, to a large extent, on the choice and targeting of stabilization strategies. In a situation where a single commodity plays a leadership role in the price dynamics of other crops, targeting intervention at such a commodity would provide a useful mechanism to reduce policy cost of price stabilization while achieving commodity-wide stabilization objectives. Using multiple cointegration analysis techniques to generate knowledge useful in targeting price stabilization intervention, this study investigates whether there is a single food crop in Ethiopia, among the three major ones (teff, wheat, and maize), with an exclusive price leadership role in the price formation process of the rest. The results show that maize price plays a leadership role in the dynamics of teff and wheat prices at all markets studied, except that of Addis Ababa teff market. Given the major evidence of a price leadership role of maize, it might be possible to achieve commodity-wide price stabilization objectives through targeting intervention on maize. Such targeted intervention may also prove efficiency in terms of reducing policy cost and public spending. Copyright © 2008 John Wiley & Sons, Ltd. [source] Prognostic significance of HER-2 status in women with inflammatory breast cancerCANCER, Issue 9 2008Shaheenah Dawood MRCP(UK) Abstract BACKGROUND Inflammatory breast cancer (IBC) is a rare, aggressive form of breast cancer with poorly understood prognostic variables. The purpose of this study was to define the prognostic impact of HER-2 status on survival outcomes of patients with IBC. METHODS In all, 179 patients with IBC, diagnosed between 1989 and 2005, with known HER-2 status, and treated with an anthracycline-based chemotherapy regimen without trastuzumab, were included in the analysis. Patients with HER-2-positive disease who received trastuzumab at the time of disease recurrence were included. Survival outcomes were estimated by the Kaplan-Meier product limit method and compared across groups using the log-rank statistic. A Cox proportional hazards model was fitted to determine the association of survival outcomes with HER-2 status after adjusting for patient and tumor characteristics. RESULTS A total of 111 patients (62%) had HER-2-negative disease and 68 (38%) had HER-2-positive disease. The median follow-up among all patients was 35 months. At the time of the analysis, 62 patients (55.9%) with HER-2-negative disease and 42 patients (61.8%) with HER-2-positive disease had a recurrence. Thirty-one patients (73.8%) with HER-2-positive disease who had a disease recurrence went on to receive trastuzumab. On univariate analysis, no statistically significant difference was observed for either recurrence-free survival (P = .75) or overall survival (P = .24) between patients who had HER-2-positive disease and those who had HER-2-negative disease. In a multivariate model, HER-2 status did not appear to significantly affect recurrence-free survival (hazards ratio [HR] of 0.75; 95% confidence interval [95% CI], 0.46,1.22 [P = .241]). In the multivariate model, patients with HER-2-positive disease had a decreased hazard of death (HR of 0.56; 95% CI, 0.34,0.93 [P = .024]) compared with patients with HER-2-negative disease. CONCLUSIONS HER-2 status, in the absence of trastuzumab, did not appear to significantly affect recurrence-free survival. After adjusting for other characteristics, the addition of trastuzumab in the metastatic setting significantly improved survival in the HER-2-positive group above and beyond that of the HER-2-negative group. This gives us further insight into the biology of this aggressive disease and underlines the major effect of targeted intervention. Cancer 2008. © 2008 American Cancer Society. [source] Cost-effectiveness of targeted and tailored interventions on colorectal cancer screening useCANCER, Issue 4 2008David R. Lairson PhD Abstract BACKGROUND. Colorectal cancer (CRC) screening is cost-effective but underused. The objective of this study was to determine the cost-effectiveness of targeted and tailored behavioral interventions to increase CRC screening use by conducting an economic analysis associated with a randomized trial among patients in a large, racially and ethnically diverse, urban family practice in Philadelphia. METHODS. The incremental costs per unit increase were measured in individuals who were screened during the 24 months after intervention. Percent increase in screening was adjusted for baseline differences in the study groups. Each intervention arm received a targeted screening invitation letter, stool blood test (SBT) cards, informational booklet, and reminder letter. Tailored interventions incrementally added tailored messages and reminder telephone calls. RESULTS. Program costs of the targeted intervention were $42 per participant. Additional costs of adding tailored print materials and of delivering a reminder telephone call were $150 and $200 per participant, respectively. The cost per additional individual screened was $319 when comparing the no intervention group with the targeted intervention group. CONCLUSIONS. The targeted intervention was more effective and less costly than the tailored intervention. Although tailoring plus reminder telephone call was the most effective strategy, it was very costly per additional individual screened. Mailed SBT cards significantly boosted CRC screening use. However, going beyond the targeted intervention to include tailoring or tailoring plus reminder calls in the manner used in this study did not appear to be an economically attractive strategy.

[source] Regulation and Role of the Presynaptic and Myocardial Na+/H+ Exchanger NHE1: Effects on the Sympathetic Nervous System in Heart FailureCARDIOVASCULAR THERAPEUTICS, Issue 2 2007Kirsten Leineweber ABSTRACT In acute myocardial ischemia and in chronic heart failure, sympathetic activation with excessive norepinephrine (NE) release from and reduced NE reuptake into sympathetic nerve endings is a prominent cause of arrhythmias and cardiac dysfunction. The Na+/H+ exchanger NHE1 is the predominant isoform in the heart. It contributes to cellular acid,base balance, and electrolyte, and volume homeostasis, and is activated in response to intracellular acidosis and/or activation of guanine nucleotide binding (G) protein-coupled receptors. NHE1 mediates its signaling via protein kinases A (PKA) or C (PKC). In cardiomyocytes, NHE1 is restricted to specialized membrane domains, where it regulates the activity of pH-sensitive proteins and modulates the driving force of the Na+/Ca2+ exchanger. During acute ischemia/reperfusion and in heart failure the activity/amount of NHE1 is increased, leading to intracellular Ca2+ overload and promoting structural (apoptosis, hypertrophy) and functional (arrhythmias, hypercontraction) myocardial damage. In sympathetic nerve endings, increased NHE1 activity results in the accumulation of axoplasmic Na+ that diminishes the inward and/or favors the outward transport of NE via the neuronal norepinephrine transporter (NET). The increased NE levels within the nerve,muscle junction facilitate the sustained stimulation of myocardial ,- and ,-adrenoceptors (ARs), which in turn aggravate the increases in myocardial NHE1 activity and the associated deleterious effects. Furthermore, the responsiveness of the ,-AR declines overtime, which results in further release of NE, initiating a vicious cycle. Accordingly, NHE1 is a potential candidate for targeted intervention to suppress this feedback loop. [source] Risk factors for obesity in childhood survivors of suprasellar brain tumours: a retrospective studyACTA PAEDIATRICA, Issue 10 2010Ngee Lek Abstract Aim:, To characterize postdiagnosis changes in body mass index (BMI) among childhood survivors of suprasellar brain tumours, and to determine the risk factors associated with obesity. Methods:, We conducted a retrospective analysis of 46 children (16 boys and 30 girls) with median (IQR) age of 7.49 (3.47,11.59) years at tumour diagnosis, and followed up for 3.93 (1.68,7.27) years. Survival analyses were used to identify risks of developing obesity. Results:, There were no sex differences in age at tumour diagnosis, duration of follow-up, tumour types, endocrinopathies, treatment modalities or baseline BMI SDS. In the first year after tumour diagnosis, ,BMI SDS (median; IQR) was greater in girls (1.32; 0.07,2.08) than in boys (0.48; ,0.40 to 0.89) (p = 0.01). At diagnosis, 3/46 children (6%) were obese; this increased to 20/46 (43%) by last follow-up (p < 0.001) and was more common in girls (17/30; 57%) than in boys (3/16; 19%). Female gender (hazard ratio 5.0, 95% CI 1.2,21.7; p = 0.04) and greater than average baseline BMI (hazard ratio 4.7, 95% CI 1.1,20.8; p = 0.02) were risk factors for subsequent obesity. Conclusion:, Accurate prediction of obesity risk is important and would allow early targeted intervention in high-risk patients. [source] Targeted group antenatal prevention of postnatal depression: a reviewACTA PSYCHIATRICA SCANDINAVICA, Issue 4 2003M.-P. Austin Objective:, To review the efficacy of antenatal group interventions aimed at reducing postnatal depression (PND) in ,at risk' women. Method:, Medline, Psyclit, HEALTHSTAR, EMBASE, Cochrane library, UK National Research Register and CINHAL searches were performed from 1960 to December 2001 focussing on randomized controlled trials (RCTs). Results:, As statistical synthesis of the studies was not feasible, a qualitative review is provided. All five studies reviewed suffer from substantial limitations including small numbers; unrealistic effect sizes; large attrition rates; lack of a systematic approach in identifying those ,at risk' and thus clinically heterogenous samples. Three of the studies used unvalidated interventions that were educational or supportive in approach. While one such study reported a benefit of intervention, the largest study using a structured intervention, reported no effect. A very small study using interpersonal therapy, was promising but needs replication with an adequate sample size. Conclusion:, There is currently little evidence from RCTs to support the implementation of antenatal group interventions to reduce PND in ,at risk' women. Further studies addressing the significant methodological limitations are recommended before concluding that antenatal targeted interventions have no place in maternity care. [source] Methamphetamine use among Australian workers and its implications for preventionDRUG AND ALCOHOL REVIEW, Issue 3 2008Professor ANN M. ROCHE Director Abstract Introduction and Aims. Little attention has been directed to the use of methamphetamine among Australian workers. To address this, a study was conducted that examined drug consumption patterns of the Australian work-force. Design and Method. A secondary analysis of the 2004 National Drug Strategy Household Survey (NDSHS) data was undertaken that focused on methamphetamine use among those in paid employment. Results. Methamphetamine use in the past 12 months was reported by 4.0% of workers compared to 2.2% of respondents not in the paid work-force. A larger proportion of male (4.8%) than female workers (3.0%) used methamphetamine. The highest prevalence occurred among 18,29-year-old workers (11.2%; males: 12.6%; females: 9.4%), and among workers in hospitality (9.5%), construction (5.4%) and transport (5.4%) industries and among tradespeople (6.5%). Significantly more methamphetamine users reported absenteeism compared to users of other illicit drugs and non-drug users. Among respondents reporting methamphetamine use, 13.4% reported absenteeism due to illicit drug use, while 56.8% reported absenteeism due to any illness or injury. Significantly more methamphetamine users (32.9%) reported going to work under the influence than users of other illicit drugs. Compared to users of other illicit drugs, methamphetamine users were also significantly more likely to drive a car, operate heavy machinery or abuse someone while under the influence. Discussion and Conclusions. The specific details of the profile of workers using methamphetamine and the impact it has on work performance allows for the development of targeted interventions and tailored prevention strategies previously not possible. [source] Dynamics of soil erosion rates and controlling factors in the Northern Ethiopian Highlands , towards a sediment budgetEARTH SURFACE PROCESSES AND LANDFORMS, Issue 5 2008Jan Nyssen Abstract This paper analyses the factors that control rates and extent of soil erosion processes in the 199 ha May Zegzeg catchment near Hagere Selam in the Tigray Highlands (Northern Ethiopia). This catchment, characterized by high elevations (2100,2650 m a.s.l.) and a subhorizontal structural relief, is typical for the Northern Ethiopian Highlands. Soil loss rates due to various erosion processes, as well as sediment yield rates and rates of sediment deposition within the catchment (essentially induced by recent soil conservation activities), were measured using a range of geomorphological methods. The area-weighted average rate of soil erosion by water in the catchment, measured over four years (1998,2001), is 14·8 t ha,1 y,1, which accounts for 98% of the change in potential energy of the landscape. Considering these soil loss rates by water, 28% is due to gully erosion. Other geomorphic processes, such as tillage erosion and rock fragment displacement by gravity and livestock trampling, are also important, either within certain land units, or for their impact on agricultural productivity. Estimated mean sediment deposition rate within the catchment equals 9·2 t ha,1 y,1. Calculated sediment yield (5·6 t ha,1 y,1) is similar to sediment yield measured in nearby catchments. Seventy-four percent of total soil loss by sheet and rill erosion is trapped in exclosures and behind stone bunds. The anthropogenic factor is dominant in controlling present-day erosion processes in the Northern Ethiopian Highlands. Human activities have led to an overall increase in erosion process intensities, but, through targeted interventions, rural society is now well on the way to control and reverse the degradation processes, as can be demonstrated through the sediment budget.

Reitzel ABSTRACT Objectives Direct and mediated associations between subjective social status (SSS), a subjective measure of socio-economic status, and smoking abstinence were examined during the period of acute withdrawal among a diverse sample of 421 smokers (33% Caucasian, 34% African American, 33% Latino) undergoing a quit attempt. Methods Logistic regressions examined relations between SSS and abstinence, controlling for socio-demographic variables. Depression, stress, positive affect and negative affect on the quit day were examined as potential affective mediators of the SSS-abstinence association, with and without adjusting for pre-quit mediator scores. Results SSS predicted abstinence to 2 weeks post-quit. Abstinence rates were 2.6 (postquit week 1) and 2.4 (postquit week 2) times higher in the highest versus the lowest SSS quartile. Depression and positive affect mediated the SSS,abstinence relationships, but only depression maintained significance when adjusting for the baseline mediator score. Conclusions Among a diverse sample of quitting smokers, low SSS predicted relapse during acute withdrawal after controlling for numerous covariates, an effect accounted for partially by quit day affective symptomatology. Smokers endorsing lower SSS face significant hurdles in achieving cessation, highlighting the need for targeted interventions encompassing attention to quit day mood reactivity. [source] Health-related quality of life measures and psychiatric comorbidity in patients with migraineEUROPEAN JOURNAL OF NEUROLOGY, Issue 9 2009M. Mula Background and purpose:, The identification of factors associated to health-related quality of life (HRQoL) measures in patients with migraine has major implications in terms of prognosis and treatment. This study aimed at investigating associations between HRQoL and comorbid mood and anxiety disorders. Methods:, Consecutive adult outpatients with a diagnosis of migraine with or without aura were assessed using the Mini International Neuropsychiatric Interview (M.I.N.I.) Plus version 5.0.0 and the Migraine-Specific Quality-of-Life Questionnaire (MSQ). Results:, Data of 112 patients (82 females), 69 without aura, mean age 41.2 ± 13.3 years were analyzed. According to the M.I.N.I., 50% patients had a lifetime or current DSM-IV diagnosis of mood or anxiety disorder. There was no between-groups difference in MSQ total and subscale scores in relation to the presence/absence of psychiatric comorbidity, independently whether that was current or lifetime. In the group of subjects with psychiatric disorders, age at onset of migraine correlated with MSQ-total (rho = ,0.407 P = 0.002), and subscale scores (Role Function-Restrictive, rho = ,0.397, P = 0.002; Emotional Function, rho = ,0.487, P < 0.001). Conclusions:, Our findings suggest that current and/or lifetime psychiatric comorbidities are not associated with HRQoL measures in patients with migraine. However, patients with migraine and psychiatric comorbidities may represent a specific subgroup deserving particular attention for targeted interventions. [source] Efficacy of skin self-examination for the early detection of melanomaINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2010Reyhaneh Hamidi BA The National Cancer Institute's "Melanoma Action Plan" calls for reduction of melanoma mortality through early detection. Routine skin self-examination (SSE) has the potential to increase chances of early detection and treatment and may be the key to melanoma survival. We provide a focused review of the accuracy of SSE for detecting premalignant lesions and cutaneous risk factors for melanoma, with suggestions for future directions for enhancing measurement of SSE accuracy and ways in which to improve the public's perceptions of melanoma efficacy. We examined published data on the efficacy of skin self-examination for the early detection of melanoma. We searched the MEDLINE database for publications between January 1, 1987 and June 1, 2007 using search terms for "melanoma" and "self-examination." We found that sensitivity of skin self-examination is low, ranging from 25% to 93%, while specificity is generally higher (83% to 97%). Attempts to increase improve the lay public's perceptions of the early signs of melanoma have proved effective, while those aimed at increasing accuracy of SSE with targeted interventions have been moderately successful. SSE's insensitivity for detection of pigmented lesions should prompt further investigation of educational interventions to enhance its accuracy and lead to its adoption as a cheap, simple screening tool. Assessment of the accuracy and efficacy of SSE should proceed using standardized definitions and measurements such that it is easier to pool data on the overall value of SSE as a screening modality. [source] Self-reported weight gain following smoking cessation: A function of binge eating behaviorINTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 6 2010Marney A. White PhD Abstract Objective This study investigated patterns of self-reported weight gain following smoking cessation among overweight individuals with and without binge eating. Method Participants were 103 overweight (BMI , 25) community volunteers who completed a battery of questionnaires online. Key items queried smoking cessation history and weight gain in the year following cessation. Participants were classified as nonbinge eating overweight (NBO, n = 56) or binge eating disorder (BED, n = 47). Results BED participants were significantly more likely to report weight gain in the year following smoking cessation than NBO participants. After controlling for current BMI, the amount of self-reported weight gain following smoking cessation differed significantly between groups, with the NBO group reporting an average gain of 5.0 kg and the BED group reporting 11.2-kg gain. Discussion Since many individuals resume smoking due to cessation-associated weight gain, these findings highlight the need for targeted interventions for overweight individuals particularly those who also binge eat. © 2009 by Wiley Periodicals, Inc.

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. [source] An examination of frequent nursing interventions and outcomes in an adolescent psychiatric inpatient unitINTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 5 2009Candace Bobier ABSTRACT:, Little is known about which nursing interventions used in adolescent psychiatric inpatient treatment demonstrate improvements in outcome in the ,real world' setting, despite an increase in external outcomes reporting requirements. This paper examines nursing and other multidisciplinary interventions commonly used at the Youth Inpatient Unit, Christchurch, New Zealand, in relation to improvements in outcomes as measured by the Health of the Nation Outcome Scales for Children and Adolescents, utilizing data gathered prospectively as part of an ongoing quality assurance and outcomes project. We found the majority of interventions investigated were utilized equally across diagnostic groups, although stress management and problem-solving education was used more for patients with mixed affective disorders. Further, the results contribute to growing evidence toward the value of providing medication and problem-solving education to this population. Mental health nurses working with children and adolescents should be supported to utilize and develop their unique skill set to offer targeted interventions and to examine their practice to identify the most valuable interventions for their patients within this developmental context. [source] Community mental health nursing: Keeping pace with care delivery?INTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 3 2008Julie Henderson ABSTRACT:, The National Mental Health Strategy has been associated with the movement of service delivery into the community, creating greater demand for community services. The literature suggests that the closure of psychiatric beds and earlier discharge from inpatient services, have contributed to an intensification of the workload of community mental health nurses. This paper reports findings from the first stage of an action research project to develop a workload equalization tool for community mental health nurses. The study presents data from focus groups conducted with South Australian community mental health nurses to identify issues that impact upon their workload. Four themes were identified, relating to staffing and workforce issues, clients' characteristics or needs, regional issues, and the impact of the health-care system. The data show that the workload of community mental health nurses is increased by the greater complexity of needs of community mental health clients. Service change has also resulted in poor integration between inpatient and community services and tension between generic case management and specialist roles resulting in nurses undertaking tasks for other case managers. These issues, along with difficulties in recruiting and retaining staff, have led to the intensification of community mental health work and a crisis response to care with less time for targeted interventions. [source] Socio-cognitive Habilitation Using the Math Interactive Learning Experience Program for Alcohol-Affected ChildrenALCOHOLISM, Issue 8 2007Julie A. Kable Background: Fetal alcohol syndrome (FAS) has been recognized as a disabling condition with a significant impact on the neurobehavioral functioning of affected individuals, including cognition, behavior, and academic functioning, but little research has been performed on targeted interventions for these children. Methods: A socio-cognitive habilitative program focused on improving behavior and math functioning in children 3 to 10 years of age (n=61) was developed and evaluated. The intervention provided parental instruction on FAS, advocacy, and behavioral regulation via workshops and interactive math tutoring with children. All families received parental instruction and were then randomly assigned to either the math instruction or standard psychoeducational care groups. Results: Satisfaction with workshops was very high, with over 90% agreeing that trainers were knowledgeable and materials easy to understand and helpful. Significant gains in knowledge were found for information provided in the instructional groups. At posttesting, caregivers reported fewer problem behaviors on the Achenbach Child Behavior Checklist, Internalizing Problem Behavior, Externalizing Problem Behavior, and Total Problem Behavior summary scales. After 5 months, both groups of children demonstrated gains in math knowledge but significantly higher gains were found in the group receiving direct math instruction. The math treatment group was also more likely to demonstrate a gain of over 1 standard deviation on any of the 4 math outcome measures used. Conclusions: These findings suggest that parents of children with fetal alcohol spectrum disorders (FAS(D)) benefit from instruction in understanding their child's alcohol-related neurological damage and strategies to provide positive behavioral supports and that targeted psychoeducational programs may be able to remediate some of the math deficits associated with prenatal alcohol exposure. [source] Frequency of high-risk use of QT-prolonging medications,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 6 2006Nancy M. Allen LaPointe PharmD Abstract Purpose Prolongation of the QT interval has been associated with increased risk of torsades de pointes and death. Concurrent use of more than one QT-prolonging drug or a QT-prolonging drug with a drug that alters its pharmacokinetic profile is an important risk factor for adverse outcomes. Methods Using a representative sample of 2 million health plan members from 10 health maintenance organizations with pharmacy benefits between January 1999 and July 2001, we identified potential drug interactions involving QT-prolonging medications. Prescription claims overlapping by at least 7 days for either 2 or more QT-prolonging drugs or a QT-prolonging drug with a drug that alters its clearance were considered potential drug interactions. We determined the number of drug interactions overall and the number of these interactions involving patients with other risk factors for torsades de pointes. Results A total of 48,465 potential drug interactions were identified in 10,415 (4.6%) of the 228,550 patients with at least one prescription for a QT-prolonging drug. Amitriptyline was involved in 37,859 (78.1%) of the drug interactions. Of all potential drug interactions, 43,689 (90.1%) occurred in patients with at least one other risk factor for torsades de pointes, and 1053 (2.2%) were listed as a contraindicated combination in product labeling. Conclusion Potential drug interactions involving currently marketed QT-prolonging drugs occurred in 4.6% of patients who had a prescription for a QT-prolonging medication. The findings suggest several areas for targeted interventions to decrease the potential risk from QT-prolonging medications. Copyright © 2005 John Wiley & Sons, Ltd. [source] Cognitive hypothesis testing and response to intervention for children with reading problemsPSYCHOLOGY IN THE SCHOOLS, Issue 8 2006Catherine A. Fiorello Response to intervention (RTI) must be combined with comprehensive cognitive assessment to identify children with learning disabilities. This article presents the Cognitive Hypothesis Testing (CHT) model for integrating RTI and comprehensive evaluation practices in the identification of children with reading disabilities. The CHT model utilizes a scientific method approach for interpreting cognitive and neuropsychological processes together with evaluation of ecological and treatment validity data to develop targeted interventions for students who do not respond to standard academic interventions. A case study highlights how CHT practices can lead to effective interventions for a child who did not respond to a phonologically based reading intervention. In addition, discriminant analyses of 128 children with reading disabilities revealed the presence of Global, Phonemic, Fluency-Comprehension, and Orthographic subtypes. Results suggest subtypes show disparate cognitive profiles that differentially impact their reading achievement, supporting our contention that individual assessment of cognitive processing strengths and weaknesses is not only necessary for identifying children with reading disabilities but also can lead to individualized interventions designed to meet their unique learning needs. © 2006 Wiley Periodicals, Inc.

[source] Framing Disparities Along the Continuum of Care from Chronic Kidney Disease to Transplantation: Barriers and InterventionsAMERICAN JOURNAL OF TRANSPLANTATION, Issue 4 2009K. Ladin Research in renal transplantation continues to document scores of disparities affecting vulnerable populations at various stages along the transplantation process. Given that both biological and environmental determinants contribute significantly to variation, identifying factors underlying an unfairly biased distribution of the disease burden is crucial. Confounded definitions and gaps in understanding causal pathways impede effectiveness of interventions aimed at alleviating disparities. This article offers an operational definition of disparities in the context of a framework aimed at facilitating interventional research. Utilizing an original framework describing the entire continuum of the transplant process from diagnosis of chronic kidney disease through successful transplant, this article explores the case of racial disparities, illustrating key factors predicting and perpetuating disparities. Though gaps in current research leave us unable to identify which stages of the transplant pathway adversely affect most people, by identifying key risk factors across the continuum of care, this article highlights areas suited for targeted interventions and presents recommendations for improvement and future research. [source] A genome wide association study for QTL affecting direct and maternal effects of stillbirth and dystocia in cattleANIMAL GENETICS, Issue 3 2010H. G. Olsen Summary Dystocia and stillbirth are significant causes of female and neonatal death in many species and there is evidence for a genetic component to both traits. Identifying causal mutations affecting these traits through genome wide association studies could reveal the genetic pathways involved and will be a step towards targeted interventions. Norwegian Red cattle are an ideal model breed for such studies as very large numbers of records are available. We conducted a genome wide association study for direct and maternal effects of dystocia and stillbirth using almost 1 million records of these traits. Genotyping costs were minimized by genotyping the sires of the recorded cows, and using daughter averages as phenotypes. A dense marker map containing 17 343 single nucleotide polymorphisms covering all autosomal chromosomes was utilized. The genotyped sires were assigned to one of two groups in an attempt to ensure independence between the groups. Associations were only considered validated if they occurred in both groups. Strong associations were found and validated on chromosomes 4, 5, 6, 9, 12, 20, 22 and 28. The QTL region on chromosome 6 was refined using LDLA analysis. The results showed that this chromosome most probably contains two QTL for direct effect on dystocia and one for direct effect on stillbirth. Several candidate genes may be identified close to these QTL. Of these, a cluster of genes expected to affect bone and cartilage formation (i.e. SPP1, IBSP and MEPE) are of particular interest and we suggest that these genes are screened in candidate gene studies for dystocia and stillbirth in cattle as well as other species. [source] Epidemiology of alcohol-related burden of disease among Indigenous AustraliansAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 2010Bianca Calabria Abstract Objective: To compare the burden of alcohol-related harm and underlying factors of this harm, by age and sex, for Indigenous and general population Australians. Methods: Population attributable fractions are used to estimate the disability adjusted life years (DALYs) for alcohol-related disease and injury. The DALYs were converted to rates per 1,000 by age and sex for the Indigenous and general populations. Results: Homicide and violence rates were much higher for Indigenous males: greatest population difference was for 30,44 years, Indigenous rate 8.9 times higher. Rates of suicide were also greater: the largest population difference was for 15,29 years, Indigenous rate 3.9 times higher. Similarly, for Indigenous females, homicide and violence rates were much higher: greatest population difference was for 30,44 years, Indigenous rate 18.1 times higher. Rates of suicide were also greater: the largest population difference was for 15,29 years, Indigenous rate 5.0 times higher. Conclusions: Alcohol consumption and associated harms are of great concern for Indigenous Australians across all ages. Violent alcohol-related harms have been highlighted as a major concern. Implications: To reduce the disproportionate burden of alcohol-related harm experienced by Indigenous Australians, targeted interventions should include the impact on families and communities and not just the individual. [source] Predictors of avascular necrosis of bone in long-term survivors of hematopoietic cell transplantationCANCER, Issue 18 2009Stephanie Campbell BA Abstract BACKGROUND: Avascular necrosis (AVN) is a debilitating condition reported after chronic steroid use. The purpose of this study was to describe the magnitude of risk in individuals who survived ,1 years after hematopoietic cell transplantation (HCT), and to investigate the role of immunosuppressive agents such as prednisone, tacrolimus (FK506), mycophenolate mofetil (MMF), and cyclosporine (CSA) in the development of AVN after HCT. METHODS: Using a retrospective study design, the authors followed 1346 eligible patients for the development of AVN. Cumulative incidence was calculated taking into consideration competing risk from death and disease recurrence. Cox proportional regression techniques were used to identify associated risk factors. RESULTS: The median age at HCT was 34 years (range, 7 months-69 years), and median length of follow-up for those surviving was 8.2 years. Seventy-five patients developed AVN of 160 joints. The cumulative incidence of AVN at 10 years was 2.9% after autologous HCT, 5.4% after allogeneic matched related donor HCT, and 15% after unrelated donor HCT (P < .001 compared with autologous HCT recipients). For allogeneic transplant recipients, male sex (relative risk [RR], 2.1; 95% confidence interval [95% CI], 1.1-4.0); presence of chronic graft-versus-host disease (RR, 2.2); and exposure to CSA, FK506, prednisone, and MMF rendered patients at increased risk, especially in patients with a history of exposure to ,3 drugs (RR, 9.2; 95% CI, 2.42-35.24). CONCLUSIONS: Future studies examining the pathogenetic mechanism underlying AVN should help develop targeted interventions to prevent this chronic debilitating condition.

[source] Caffeinated Cocktails: Energy Drink Consumption, High-risk Drinking, and Alcohol-related Consequences among College StudentsACADEMIC EMERGENCY MEDICINE, Issue 5 2008Mary Claire O'Brien MD Abstract Objectives:, The consumption of alcohol mixed with energy drinks (AmED) is popular on college campuses in the United States. Limited research suggests that energy drink consumption lessens subjective intoxication in persons who also have consumed alcohol. This study examines the relationship between energy drink use, high-risk drinking behavior, and alcohol-related consequences. Methods:, In Fall 2006, a Web-based survey was conducted in a stratified random sample of 4,271 college students from 10 universities in North Carolina. Results:, A total of 697 students (24% of past 30-day drinkers) reported consuming AmED in the past 30 days. Students who were male, white, intramural athletes, fraternity or sorority members or pledges, and younger were significantly more likely to consume AmED. In multivariable analyses, consumption of AmED was associated with increased heavy episodic drinking (6.4 days vs. 3.4 days on average; p < 0.001) and twice as many episodes of weekly drunkenness (1.4 days/week vs. 0.73 days/week; p < 0.001). Students who reported consuming AmED had significantly higher prevalence of alcohol-related consequences, including being taken advantage of sexually, taking advantage of another sexually, riding with an intoxicated driver, being physically hurt or injured, and requiring medical treatment (p < 0.05). The effect of consuming AmED on driving while intoxicated depended on a student's reported typical alcohol consumption (interaction p = 0.027). Conclusions:, Almost one-quarter of college student current drinkers reported mixing alcohol with energy drinks. These students are at increased risk for alcohol-related consequences, even after adjusting for the amount of alcohol consumed. Further research is necessary to understand this association and to develop targeted interventions to reduce risk. [source] |
