Survival in Danish patients with breast cancer and inflammatory bowel disease: A nationwide cohort study,

INFLAMMATORY BOWEL DISEASES, Issue 4 2008
Kirstine Kobberøe Søgaard BA
Abstract Background: Incidences of inflammatory bowel disease (IBD) and of breast cancer have increased over the last decades. The influence of IBD on breast cancer prognosis, however, is unknown. We therefore examined the impact of IBD on treatment receipt and survival in breast cancer patients. Methods: Information on breast cancer patients (stage and treatment) diagnosed between 1980 and 2004 was sourced from the Danish Cancer Registry. Data on IBD and potential confounders were extracted from the Danish National Registry of Patients covering all Danish hospitals. Cox regression was used to compute mortality rate ratios (MRRs) among breast cancer patients with IBD, compared to their non-IBD counterparts, adjusting for age, stage, comorbidity measured by the Charlson Index, and calendar year. Results: We identified 71,148 breast cancer cases; 67 also had Crohn's disease (CD) and 216 had ulcerative colitis (UC). Patients with CD had more advanced stage and received radiotherapy less, and chemotherapy more, frequently than patients without IBD. In the adjusted analyses there was no substantial survival difference in breast cancer patients with and without IBD (MRRCD = 1.22; 95% confidence interval [CI] = 0.85,1.75; MRRUC = 1.09; 95% CI = 0.86,1.38). In a stratified analysis, chemotherapy was associated with poorer survival in patients with CD (MRRCD = 1.93; 95% CI = 1.00,3.72). Conclusions: Breast cancer patients with UC receive the same treatment and have similar survival to breast cancer without IBD. In contrast, breast cancer patients with CD are treated with radiotherapy less often. Survival of breast cancer in patients with CD treated with chemotherapy is poorer compared to survival in patients without IBD. (Inflamm Bowel Dis 2007) [source]

The Association Between Emergency Medical Technician-Basic (EMT-B) Exam Score, Length of EMT-B Certification, and Success on the National Paramedic Certification Exam

ACADEMIC EMERGENCY MEDICINE, Issue 9 2009
Antonio R. Fernandez MS, NREMT-P
Abstract Objectives:, Factors that affect success on the national paramedic certification examination have been identified. However, there are no known studies that have examined success on the paramedic exam with respect to either Emergency Medical Technician-Basic (EMT-B) examination score or length of EMT-B certification (which may reflect field experience gained prior to enrolling in paramedic training). The objectives of this study included assessing the relationship of EMT-B examination score and length of EMT-B certification to success on the national paramedic certification examination. Methods:, Study data were obtained from the National Registry of EMTs (NREMT). First attempts of the NREMT paramedic certification exam from 2002 to 2006 were included. To assure that EMT-B certification exam scores were recorded, analysis was limited to individuals in the 14 states that have utilized NREMT for initial certification of both EMT-Bs and paramedics since January 1, 1997. This also facilitated accurate calculations of the length of EMT-B certification. Results:, There were 11,163 individuals meeting inclusion criteria, and a complete case analysis was performed on 9,148, of whom 5,826 (63.7%) passed the national paramedic exam. The mean (±SD) score on the EMT-B cognitive exam was 75.5 (±6.4%), and the mean (±SD) length of EMT-B certification prior to paramedic testing was 3.2 (±2.3) years. When placed in a logistic regression model, the EMT-B exam score variable was categorized in quartiles (,71%, 72%,75%, 76%,79%, and ,80%), and the length of EMT-B certification variable was dichotomized (,1.6 years vs. >1.6 years). With respect to paramedic exam success, after controlling for known confounders, there was an increase in the odds ratio (OR) across each of the quartiles of EMT-B exam score. The largest difference was seen when comparing the lowest and highest quartiles (paramedic exam pass rates of 45.6 and 80.8%, respectively; OR = 5.4, 95% confidence interval [CI] = 4.7 to 6.2). Individuals whose length of EMT-B certification was >1.6 years had increased odds of passing the paramedic examination (OR = 1.2, 95% CI = 1.1 to 1.3). The multivariable logistic regression model demonstrated good fit (p = 0.62). Conclusions:, Both EMT-B examination score and ength of EMT-B certification are associated with success on first attempt at the cognitive portion of the national paramedic certification exam. Educators may wish to consider these two factors when determining paramedic program admission standards and/or consider these variables when determining how to allocate program resources. [source]


Autoantibodies to a 140-kd protein in juvenile dermatomyositis are associated with calcinosis

ARTHRITIS & RHEUMATISM, Issue 6 2009
H. Gunawardena
Objective The identification of novel autoantibodies in juvenile dermatomyositis (DM) may have etiologic and clinical implications. The aim of this study was to describe autoantibodies to a 140-kd protein in children recruited to the Juvenile DM National Registry and Repository for UK and Ireland. Methods Clinical data and sera were collected from children with juvenile myositis. Sera that recognized a 140-kd protein by immunoprecipitation were identified. The identity of the p140 autoantigen was investigated by immunoprecipitation/immunodepletion, using commercial monoclonal antibodies to NXP-2, reference anti-p140, and anti-p155/140, the other autoantibody recently described in juvenile DM. DNA samples from 100 Caucasian children with myositis were genotyped for HLA class II haplotype associations and compared with those from 864 randomly selected UK Caucasian control subjects. Results Sera from 37 (23%) of 162 patients with juvenile myositis were positive for anti-p140 autoantibodies, which were detected exclusively in patients with juvenile DM and not in patients with juvenile DM,overlap syndrome or control subjects. No anti-p140 antibody,positive patients were positive for other recognized autoantibodies. Immunodepletion suggested that the identity of p140 was consistent with NXP-2 (the previously identified MJ autoantigen). In children with anti-p140 antibodies, the association with calcinosis was significant compared with the rest of the cohort (corrected P < 0.005, odds ratio 7.0, 95% confidence interval 3.0,16.1). The clinical features of patients with anti-p140 autoantibodies were different from those of children with anti-p155/140 autoantibodies. The presence of HLA,DRB1*08 was a possible risk factor for anti-p140 autoantibody positivity. Conclusion This study has established that anti-p140 autoantibodies represent a major autoantibody subset in juvenile DM. This specificity may identify a further immunogenetic and clinical phenotype within the juvenile myositis spectrum that includes an association with calcinosis. [source]


Treatment for myeloid leukaemia of Down syndrome: population-based experience in the UK and results from the Medical Research Council AML 10 and AML 12 trials

BRITISH JOURNAL OF HAEMATOLOGY, Issue 5 2006
Anupama Rao
Summary Down syndrome (DS) children are at an increased risk of developing myelodysplasia and acute myeloid leukaemia (AML). We retrospectively analysed the population-based data on 81 children with myeloid leukaemia of Down syndrome (ML-DS) from the UK National Registry of Childhood Tumours and experience in the Medical Research Council (MRC) AML 10 and AML 12 trials, which enrolled 46 children with ML-DS from 1988 to 2002. Eight per cent of UK children with AML had DS, but DS children comprised only 5% of children registered in MRC trials. The unique clinical characteristics of ML-DS were confirmed. Overall survival (OS) of ML-DS at 5 years increased from 47% in UK children diagnosed from 1988 to 1995 to 75% in children diagnosed from 1996 to 2002. OS for DS children registered in AML 10 and AML 12 was 74% in 5 years and improved from AML 10 to AML 12 (56% vs. 83%) There was no significant difference in OS between DS and non-DS children (OS: 74% vs. 62%, P = 0·4) in the trials, but this result masked a significant increase in early death amongst DS children, with a significant reduction in mortality later on. Relapse was significantly reduced (3% vs. 39%, P = 0·0003), leading to the improved disease-free survival (83% vs. 56%, P = 0·02). Given the increased number of earl treatment-related deaths, future treatment protocols should aim to reduce chemotherapy dosage or intensity whilst maintaining low rates of resistant and recurrent disease.

Noninvasive Ventilation Outcomes in 2,430 Acute Decompensated Heart Failure Patients: An ADHERE Registry Analysis

ACADEMIC EMERGENCY MEDICINE, Issue 4 2008
Thomas A. Tallman DO
Abstract Objectives:, Continuous or bilevel positive airway pressure ventilation, called noninvasive ventilation (NIV), is a controversial therapy for acute decompensated heart failure (ADHF). While NIV is considered safe and effective in patients with chronic obstructive pulmonary disease (COPD), clinical trial data that have addressed safety in ADHF patients are limited, with some suggestion of increased mortality. The objective of this study was to assess mortality outcomes associated with NIV and to determine if a failed trial of NIV followed by endotracheal intubation (ETI) (NIV failure) is associated with worse outcomes, compared to immediate ETI. Methods:, This was a retrospective analysis of the Acute Decompensated Heart Failure National Registry (ADHERE), which enrolls patients with treatment for, or with a primary discharge diagnosis of, ADHF. The authors compared characteristics and outcomes in four groups: no ventilation, NIV success, NIV failure, and ETI. One-way analysis of variance or Wilcoxon testing was performed for continuous data, and chi-square tests were used for categorical data. In addition, multivariable logistic regression was used to adjust mortality comparisons for risk factors. Results:, Entry criteria were met by 37,372 patients, of which 2,430 had ventilation assistance. Of the ventilation group, 1,688 (69.5%) were deemed NIV success, 72 (3.0%) were NIV failures, and 670 (27.6%) required ETI. The NIV failure group had the lowest O2 saturation (SaO2) (84 ± 16%), compared to either NIV success (89.6 ± 10%) or ETI (88 ± 13%; p = 0.017). ETI patients were more likely to receive vasoactive medications (p < 0.001) than the NIV success cohort. When comparing NIV failures to ETI, there were no differences in treatment during hospitalization (p > 0.05); other than that the NIV failure group more often received vasodilators (68.1% vs. 54.3%; p = 0.026). In-hospital mortality was 7.9% with NIV, 13.9% with NIV failure, and 15.4% with ETI. After risk adjustment, the mortality odds ratio for NIV failure versus ETI increased to 1.43, although this endpoint was not statistically significant. Conclusions:, In this analysis of ADHF patients receiving NIV to date, patients placed on NIV for ADHF fared better than patients requiring immediate ETI. Patients who failed NIV and required ETI still experienced lower mortality than those initially placed on ETI. Thus, while the ETI group may be more severely ill, starting therapy with NIV instead of immediate ETI will likely not harm the patient. When ETI is required, mortality and length of stay may be adversely affected. Since a successful trial of NIV is associated with improved outcomes in patients with ADHF, application of this therapy may be a reasonable treatment option. [source]


Estimating the Probability of Passing the National Paramedic Certification Examination

ACADEMIC EMERGENCY MEDICINE, Issue 3 2008
Antonio R. Fernandez BS, NREMT-P
Abstract Objectives:, It is hypothesized that student and program characteristics will influence the probability of passing the national paramedic certification exam. The objective of this study was to utilize student and program characteristics to build a statistical model to determine the probability of success on the cognitive portion of the national paramedic certification exam. Methods:, The study population for this analysis consisted of graduates attempting the National Registry of Emergency Medical Technicians (NREMT) paramedic written examination from January 1, 2002, through December 31, 2002. To be included in this analysis, graduates must have been first-time testers and have completed a survey attached to the exam. Independent variables analyzed reflected program and student characteristics derived from the survey questions and the NREMT application. A multivariable logistic regression model was fit to the outcome (pass/fail) of the examination. Results:, Complete demographic and survey data were available for 5,208 (86.8%) individuals. The final multivariable logistic regression model included nine independent variables. There were two programmatic characteristics (national accreditation and instructor qualification), six student characteristics (high school class rank, years of education, required for employment, age, race, and gender), and one graduate characteristic (elapsed time since course completion) that had a significant effect on the probability of passing the examination. Conclusions:, National program accreditation, lead instructor qualifications, student educational background, and student demographics are all significantly associated with the probability of success on the national paramedic certification examination. This model can be used by program directors, paramedic program instructors, and prospective paramedic students to maximize the probability of attaining national paramedic certification. [source]


Guideline Implementation Research: Exploring the Gap between Evidence and Practice in the CRUSADE Quality Improvement Initiative

ACADEMIC EMERGENCY MEDICINE, Issue 11 2007
Andra L. Blomkalns MD
Translating research results into routine clinical practice remains difficult. Guidelines, such as the 2002 American College of Cardiology/American Heart Association Guidelines for the Management of Patients with Unstable Angina and non-ST-segment elevation myocardial infarction, have been developed to provide a streamlined, evidence-based approach to patient care that is of high quality and is reproducible. The Can Rapid Risk Stratification of Unstable Angina Patients Suppress ADverse Outcomes with Early Implementation (CRUSADE) Quality Improvement Initiative was developed as a registry for non,ST-segment elevation acute coronary syndromes to track the use of guideline-based acute and discharge treatments for hospitalized patients, as well as outcomes associated with the use of these treatments. Care for more than 200,000 patients at more than 400 high-volume acute care hospitals in the United States was tracked in CRUSADE, with feedback provided to participating physicians and hospitals regarding their performance over time and compared with similar institutions. Such access to data has proved important in stimulating improvements in non,ST-segment elevation acute coronary syndromes care at participating hospitals for delivery of acute and discharge guideline-based therapy, as well as improving outcomes for patients. Providing quality improvement methods such as protocol order sets, continuing education programs, and a CRUSADE Quality Improvement Initiative toolbox serve to actively stimulate physician providers and institutions to improve care. The CRUSADE Initiative has also proven to be a fertile source of research in translation of treatment guidelines into routine care, resulting in more than 52 published articles and 86 abstracts presented at major emergency medicine and cardiology meetings. The cycle for research of guideline implementation demonstrated by CRUSADE includes four major steps,observation, intervention, investigation, and publication,that serve as the basis for evaluating the impact of any evidence-based guideline on patient care. Due to the success of CRUSADE, the American College of Cardiology combined the CRUSADE Initiative with the National Registry for Myocardial Infarction ST-segment elevation myocardial infarction program to form the National Cardiovascular Data Registry,Acute Coronary Treatment & Intervention Outcomes Network Registry beginning in January 2007.

ACTA OPHTHALMOLOGICA, Issue 6 2005
Gunnar Már Zoega
Abstract. Purpose:,To study the relationship between screening compliance and visual outcome in a screening programme for diabetic eye disease. Methods:,A retrospective case control study. The screening compliance of all the diabetes patients (n = 22) listed at the Icelandic National Registry for the Blind (visual acuity <0.3) was compared to a matched group of 44 non-blind diabetes patients (visual acuity ,0.3) who participated in the same screening programme for diabetic retinopathy. Glycaemic control (HbA1c), office blood pressure and cholesterol levels were assessed. Results:,The study group had a significantly lower level of compliance with the screening programme (27% ± 38% [mean ± SD] versus 77% ± 26% [mean ± SD]; p < 0.0001). Macular oedema or proliferative diabetic retinopathy was found in 60% (13/22) of the study group when entering the screening programme, compared to 7% (3/44) in the control group. Blood pressure (except diastolic BP among type 1 diabetes mellitus), blood glucose and cholesterol levels were identical. The prevalence of blindness and low vision amongst diabetes patients in Iceland is about 0.5%. Conclusions:,There was a significant relationship between screening compliance and visual outcome in diabetes patients in our screening programme. [source]

BJOG 2010;117:274,281. Objective, Preterm delivery has been shown to be associated with subsequent maternal cardiovascular morbidity. However, the impact of the severity and recurrence of preterm delivery on the risk of specific cardiovascular events and the metabolic syndrome in the mother, have not been investigated. Design, National registry-based retrospective cohort study. Setting, Women delivering in Denmark from 1978 to 2007. Population, Women with a first singleton delivery (n = 782 287), and with a first and second singleton delivery (n = 536 419). Methods, Cox proportional hazard models, with the gestational age stratified into four groups as primary exposure. We made adjustments for maternal age, year of delivery, hypertensive pregnancy disorders, fetal growth deviation, placental abruption and stillbirth. Main outcome measures, Subsequent maternal hypertension, ischaemic heart diseases, thromboembolism and type-II diabetes. Results, After a first delivery at 32,36 completed weeks of gestation, the adjusted risk of subsequent type-II diabetes increased 1.89-fold (1.69,2.10) and the risk of thromboembolism increased 1.42-fold (1.24,1.62). Women having a preterm delivery in the first pregnancy and a term delivery in the second had a 1.58-fold (1.34,1.86) increased risk of type-II diabetes and a 1.18-fold (0.96,1.44) increased risk of thromboembolism. Women having two preterm deliveries had a 2.30-fold (1.71,3.10) increased risk of type-II diabetes and a 1.80-fold (1.29,2.50) increased risk of thromboembolism. Conclusions, Preterm delivery is independent of other pregnancy complications associated with subsequent maternal overt type-II diabetes and thromboembolism. The recurrence of preterm delivery will augment these risks. [source]


The International Quotidian Dialysis Registry: Annual Report 2007

HEMODIALYSIS INTERNATIONAL, Issue 3 2007
Gihad E. NESRALLAH
Abstract In view of the need to study both intermediate and definitive outcomes associated with daily and extended-hours hemodialysis (HD), our group has undertaken the design and implementation of an international registry to collect data describing the treatments and outcomes of patients treated with these regimens. The International Quotidian Dialysis Registry began recruiting patients in June 2004. There are currently 229 patients enrolled in the registry, up from 199 last year. The projected growth is 2000 patients by 2008. This paper constitutes the third annual report of progress of patient and center recruitment, and includes descriptive data drawn from the 3 primary patient groups currently tracked by the registry: home nocturnal, home short-daily, and in-center short-daily HD. As the cohort grows, patients will be compared with control subjects drawn from their respective national registries, and comparative analyses will follow. [source]


Towards a European registry of severe allergic reactions: current status of national registries and future needs

To cite this article: Worm M, Timmermans F, Moneret-Vautrin A, Muraro A, Malmheden Yman II, Lövik M, Hattersley S, Crevel R. Towards a European registry of severe allergic reactions: current status of national registries and future needs. Allergy 2010; 65: 671,680. Abstract The incidence of severe allergic reactions is largely unknown and information about triggering allergens, aggravating factors, demography of patients and medical care is lacking. A European wide registry could provide a powerful tool to improve the management of severe allergic reactions from both a medical and a public health perspective. Analysis of existing registries regarding the type and quality of data being collected was used to develop a plan for a pan-European registry, including the type of system to be used and the range of data to be entered. Surveillance will provide evidence for the efficacy of risk management measures and may identify the emergence of new allergenic foods, and aid monitoring of novel foods, ingredients and technologies. Patients need a clear indication of factors that may increase their risk of having an adverse reaction, which such a registry can help compile. Based on the collected data, food businesses will be able to develop educational programmes for allergen risk assessment and allergen risk communication. Finally, and most importantly preventive measures can be developed and government agencies receive population based data which may be relevant for legislative purposes. [source]


Gastrointestinal stromal tumors (GIST) in children and adolescents: A comprehensive review of the current literature

PEDIATRIC BLOOD & CANCER, Issue 7 2009
Martin Benesch MD
Abstract Standards for the management of gastrointestinal stromal tumors (GIST) in children do presently not exist. Thus a systematic review and summary of the current literature was conducted serving as a basis for the further development of optimal management strategies for childhood GIST within a cooperative network. Presently 21 cases with familial GIST, and more than 100 pediatric cases each with Carney triad or sporadic GIST have been published so far. An international prospective registration based on national registries has recently started to acquire more clinical and molecular data and to develop appropriate management strategies for children and adolescents with GIST.

Guidelines for the use of recombinant activated factor VII (rFVIIa) in uncontrolled bleeding: a report by the Israeli Multidisciplinary rFVIIa Task Force

JOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 4 2005
U. MARTINOWITZ
Summary.,Background:,Recombinant activated factor VII (rFVIIa) has been approved by the U.S. Food and Drug Administration (FDA) for almost a decade for hemophilic patients with inhibitors. Its off-label use as a hemostatic agent in massive bleeding caused by a wide array of clinical scenarios is rapidly expanding. While evidence-based guidelines exist for rFVIIa treatment in hemophilia, none are available for its off-label use. Objectives:,The aim of this study is to develop expert recommendations for the use of rFVIIa in patients suffering from uncontrolled bleeding (with special emphasis on trauma) until randomized, controlled trials allow for the introduction of more established evidence-based guidelines. Methods:,A multidisciplinary task force comprising representatives of the relevant National Medical Associations, experts from the Medical Corps of the Army, Ministry of Health and the Israel National Trauma Advisory Board was established in Israel. Recommendations were construed based on the analysis of the first 36 multi-trauma patients accumulated in the prospective national registry of the use of rFVIIa in trauma, and an extensive literature search consisting of published and prepublished controlled animal trials, case reports and series. The final consensus guidelines, together with the data of the first 36 trauma patients treated in Israel, are presented in this article. Results:,Results of the first 36 trauma patients: The prolonged clotting assays [prothrombin time (PT) and partial thromboplastin time (PTT)] shortened significantly within minutes following administration of rFVIIa. Cessation of bleeding was achieved in 26 of 36 (72%) patients. Acidosis diminished the hemostatic effect of the drug, while hypothermia did not affect it. The survival rate of 61% (22/36) seems to be favorable compared with published series of similar, or less severe, trauma patients (range 30%,57%). Conclusions:,As a result of the lack of controlled trials, our guidelines should be considered as suggestive rather than conclusive. However, they provide a valuable tool for physicians using rFVIIa for the expanding off-label clinical uses. [source]


Evaluation of Naranjo Adverse Drug Reactions Probability Scale in causality assessment of drug-induced liver injury

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 9 2008
M. GARCÍA-CORTÉS
Summary Background, Causality assessment in hepatotoxicity is challenging. The current standard liver-specific Council for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method scale is complex and difficult to implement in daily practice. The Naranjo Adverse Drug Reactions Probability Scale is a simple and widely used nonspecific scale, which has not been specifically evaluated in drug-induced liver injury. Aim, To compare the Naranjo method with the standard liver-specific Council for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method scale in evaluating the accuracy and reproducibility of Naranjo Adverse Drug Reactions Probability Scale in the diagnosis of hepatotoxicity. Methods, Two hundred and twenty-five cases of suspected hepatotoxicity submitted to a national registry were evaluated by two independent observers and assessed for between-observer and between-scale differences using percentages of agreement and the weighted kappa (,w) test. Results, A total of 249 ratings were generated. Between-observer agreement was 45% with a ,w value of 0.17 for the Naranjo Adverse Drug Reactions Probability Scale, while there was a higher agreement when using the Council for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method scale (72%, ,w: 0.71). Concordance between the two scales was 24% (,w: 0.15). The Naranjo Adverse Drug Reactions Probability Scale had low sensitivity (54%) and poor negative predictive value (29%) and showed a limited capability to distinguish between adjacent categories of probability. Conclusion, The Naranjo scale lacks validity and reproducibility in the attribution of causality in hepatotoxicity. [source]


Occupational exposure to UV light and mortality from multiple sclerosis,

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 5 2009
M. Westberg MD
Abstract Background The etiology of multiple sclerosis (MS) is largely unknown; low exposure to ultraviolet (UV) light has been a suggested risk factor. The aim of this study was to investigate whether occupational exposure to UV light reduces the risk of death from MS. Methods The cohort was based on all individuals in the Swedish census in 1980. All MS-related deaths were identified in the national registry of causes of death. A job-exposure matrix was developed to classify the occupational exposure to UV light. Results MS was recorded as a cause of the death for 839 individuals. The risk of MS-related death decreased with increasing occupational exposure to UV light. The relative risk adjusted for age, sex, and socioeconomic status was 0.48 (95% CI 0.28,0.80) in the high-exposure group and 0.88 (95% CI 0.73,1.06) in the intermediate-exposure group. Conclusions Occupational exposure to UV light was associated with a reduced risk of MS. Our findings are corroborated by previous observations that UV light has a preventive role in the development of MS, although the possibility of reversed causality cannot be completely ruled out. Am.

Down syndrome in births near landfill sites

PRENATAL DIAGNOSIS, Issue 13 2007
Lars Jarup
Abstract Objectives The aim of the study was to examine the risk of giving birth to a child with Down syndrome associated with residence near landfill sites in England and Wales. Methods A 2-km zone around 6289 landfill sites processing special (hazardous), non-special and unknown waste type was used to indicate exposure. Postcodes within the 2-km zone were classified as ,exposed' and people living beyond 2 km comprised the reference population. Health outcome data were Down syndrome registrations from a national registry including 21 cytogenetic laboratories in England and Wales, for the years 1989 to 1998. With a Bayesian regression model, we calculated relative risks for the population living within 2 km of landfill sites relative to the reference population, assuming a common relative risk for all landfill sites. Adjustments were made for major confounders. Results There were 4640 cases of Down syndrome within 2 km of a landfill site. We found no excess risks of Down syndrome related to landfill sites. Adjustment for socio-economic status (SES) did not influence our estimates. There were no differences in risk between hazardous waste sites and other landfill sites. Conclusion We found no excess risk of Down syndrome in populations living near landfill sites. Copyright © 2007 John Wiley & Sons, Ltd. [source]


Epidemiology of cancer-related fatigue in the Swedish twin registry

CANCER, Issue 9 2005
M.P.H., Michael J. Forlenza Ph.D.
Abstract BACKGROUND Estimates of the prevalence of cancer-related fatigue (CRF) are wide, and data suggest that fatigue is more prevalent among cancer patients than among the general population. However, most studies examining the prevalence of CRF have been hospital-based or clinic-based studies, which often are subject to bias. METHODS Point prevalence and prevalence odds ratios of fatigue were estimated using data from a large, population-based cohort that was screened for fatigue and linked with national registry-based data about cancer. Prevalence odds ratios and 95% confidence intervals were calculated using logistic regression with general estimating equations. RESULTS Approximately 23% of cancer registrants reported abnormal fatigue in the previous 6 months, 19% reported abnormal fatigue that lasted for at least 1 month, 14% reported abnormal fatigue that lasted at least 6 months, and 11% reported abnormal fatigue that lasted at least 6 months and caused significant functional impairment. Individuals who were listed in the cancer registry within the last 5 years were more likely to report experiencing fatigue than individuals who were not listed. There was an elevated prevalence of fatigue among those who were registered with carcinomas of the lung, uterine cervix, colon-rectum, ovaries, and prostate. Both women and men who were listed recently in the cancer registry were more likely to experience any level of fatigue than the comparison group. However, a greater proportion of women experienced fatigue relative to men. CONCLUSIONS A greater proportion of individuals who were listed in a national cancer registry reported experiencing fatigue compared with individuals in the general population.

Long-term failure and function after restorative proctocolectomy , a multi-centre study of patients from the UK national ileal pouch registry

COLORECTAL DISEASE, Issue 5 2010
P. P. Tekkis
Abstract Objective, There is little information on the long-term failure and function after restorative proctocolectomy (RPC). The results of data submitted to a national registry were analysed. Method, The UK National Pouch Registry was established in 2004. By 2006, it comprised data collected from ten centres between 1976 and 2006. The long-term failure and functional outcome were determined. Trends over time were assessed using the gamma statistic or the Kruskal,Wallis statistic wherever appropriate. Results, In all, 2491 patients underwent primary RPC over a median of 54 months (range 1 month to 28.9 years). Of these, 127 (5.1%) underwent abdominal salvage surgery. The incidence of failure (excision or indefinite diversion) was 7.7% following primary and 27.5% following salvage RPC (P < 0.001). The median frequency of defaecation/24 h was five including one at night. Nocturnal seepage occurred in 8% at 1 year, rising to 15.4% at 20 years (P = 0.037). Urgency was experienced by 5.1% of patients at 1 year rising to 9.1% at 15 years (P = 0.022). Stool frequency and the need for antidiarrhoeal medication were greater following salvage RPC. Conclusion, In patients retaining anal function after RPC, frequency of defaecation was stable over 20 years. Faecal urgency and minor incontinence worsened with time. Function after salvage RPC was significantly worse. [source]
