    Mazzoncini R, Donoghue K, Hart J, Morgan C, Doody GA, Dazzan P, Jones PB, Morgan K, Murray RM, Fearon P. Illicit substance use and its correlates in first episode psychosis. Objective:, To determine if substance use (particularly cannabis) is more frequent among first episode psychosis patients and associated with a more problematic clinical presentation. Method:, All first episode psychosis (FEP) patients presenting to secondary services were recruited from London and Nottingham, over 2 years, in the Aetiology and Ethnicity of Schizophrenia and Other Psychoses study broad framework. Clinical and sociodemographic variables were assessed using a set of standardized instruments. A schedule was created to retrospectively collate substance use data from patients, relatives and clinicians. Results:, Five hundred and eleven FEP were identified. They used three to five times more substances than general population. Substance use was associated with poorer social adjustment and a more acute mode of onset. Cannabis use did not affect social adjustment, but was associated with a more acute mode of onset. Conclusion:, Cannabis has a different impact on FEP than other substances. Large epidemiological studies are needed to disentangle cannabis effect. [source]


    ,Numbness of the feet' is a poor indicator for polyneuropathy in Type 2 diabetic patients

    DIABETIC MEDICINE, Issue 2 2000
    L. V. Franse
    Summary Aims To identify neuropathic sensory symptoms associated with a clinical neurological examination (CNE) and to investigate whether these symptoms could be used as a diagnostic or screening tool for diabetic polyneuropathy in general practice. Methods Five hundred and eighty-eight patients with Type 2 diabetes, recruited from 26 general practices in the Netherlands, underwent a CNE and completed a diabetes symptom checklist that included 10 items on neuropathic sensory symptoms. Linear regression analyses were performed to assess the association between neuropathic symptoms and CNE. Receiver operating characteristic (ROC) curves were created to assess the diagnostic properties of neuropathic symptoms. Results In this population, with a mean age of 66.8 years, 32% were identified with diabetic polyneuropathy according to the CNE. Variables that showed the strongest association with CNE score were age (, = 0.41), symptoms of sensory alteration (, = 0.27), and the item ,numbness of the feet' (, = 0.35) in particular. ROC curves showed that prediction of diabetic polyneuropathy from these symptoms was unsatisfying. The sensitivity and specificity of daily symptoms of ,numbness of the feet' were 28% and 93%, respectively, in patients <,68 years, and 22% and 92%, respectively, in patients ,,68 years. Conclusions Identification of neuropathic sensory symptoms is not useful as a diagnostic or even a screening tool in the assessment of diabetic neuropathy in daily practice. Therefore, the results reported in this paper mandate an annual foot examination by the general practitioner. [source]


    Survey of major chronic iIlnesses and hospital admissions via the emergency department in a randomized older population in Randwick, Australia

    EMERGENCY MEDICINE AUSTRALASIA, Issue 4 2002
    Daniel KY Chan
    Abstract Objective: To find out if patients with chronic illnesses living in the community are at risk of unplanned hospital admissions through emergency departments; what types of chronic illnesses may be putative risk factors; and if an increase in the number of chronic illnesses may be associated with increased risk. Methods: The survey included the completion of a standardized questionnaire for medical illnesses in a random sample of older people dwelling in the community and analysis of admission records to our hospital. The principal diagnoses for admissions were recorded. The risk factors for admissions were analysed. Results: Five hundred and twenty-six (239 men and 287 women) people aged 55 years and over were interviewed. Musculoskeletal disorders, hypertension, gastrointestinal disorders and ischaemic heart disease were the most frequently reported of the chronic illnesses surveyed. A total number of 70 people from the survey group with a total of 115 admissions through emergency departments were recorded. Using logistic regression model, hypertension, ischaemic heart disease and age were found to be risk factors for emergency admissions amongst this group of community-dwelling residents. The ratios were 2.03 (95% confidence interval (CI): 1.2,3.44), 2.02 (95% CI: 1.16,3.49) and 1.05 (95% CI: 1.02,1.09), respectively. Furthermore, multiple (three or more) chronic illnesses were found to be a strong predictor of hospital admission via emergency department (chi-square = 16.647, DF = 1, P -value < 0.001). Conclusion: We conclude that there was significant association between multiple chronic diseases and emergency admissions for older people. Of these, hypertension and ischaemic heart disease were found to be significant predictors. Age per se was found to be of borderline significance. [source]


    Long-term effectiveness of computer-generated tailored patient education on benzodiazepines: a randomized controlled trial

    ADDICTION, Issue 4 2008
    Geeske Brecht Ten Wolde
    ABSTRACT Aims Chronic benzodiazepine use is highly prevalent and is associated with a variety of negative health consequences. The present study examined the long-term effectiveness of a tailored patient education intervention on benzodiazepine use. Design A randomized controlled trial was conducted comprising three arms, comparing (i) a single tailored intervention; (ii) a multiple tailored intervention and (iii) a general practitioner letter. The post-test took place after 12 months. Participants Five hundred and eight patients using benzodiazepines were recruited by their general practitioners and assigned randomly to one of the three groups. Intervention Two tailored interventions, the single tailored intervention (patients received one tailored letter) and the multiple tailored intervention (patients received three sequential tailored letters at intervals of 1 month), were compared to a short general practitioner letter that modelled usual care. The tailored interventions not only provided different and more information than the general practitioner letter; they were also personalized and adapted to individual baseline characteristics. The information in both tailored interventions was the same, but in the multiple tailored intervention the information was provided to the participants spread over three occasions. In the multiple tailored intervention, the second and the third tailored letters were based on short and standardized telephone interviews. Measurements Benzodiazepine cessation at post-test was the outcome measure. Findings The results showed that participants receiving the tailored interventions were twice as likely to have quit benzodiazepine use compared to the general practitioner letter. Particularly among participants with the intention to discontinue usage at baseline, both tailored interventions led to high percentages of those who actually discontinued usage (single tailored intervention 51.7%; multiple tailored intervention 35.6%; general practitioner letter 14.5%). Conclusions It was concluded that tailored patient education can be an effective tool for reducing benzodiazepine use, and can be implemented easily. [source]


    Incidence of Traumatic Lumbar Puncture

    ACADEMIC EMERGENCY MEDICINE, Issue 2 2003
    Kaushal H. Shah MD
    Abstract Objective: To determine the incidence of traumatic lumbar puncture (LP). Methods: A retrospective study was conducted at an urban, university tertiary care referral center with 50,000 annual emergency department (ED) visits. The study population included all patients who had cerebrospinal fluid (CSF) samples sent to the laboratory between August 15, 2000, and August 14, 2001. The numbers of red blood cells (RBCs) recorded in the first and last CSF tubes, the location where the LP was performed, and the discharge summary and the discharge diagnoses from the particular visit were obtained. All patients with intracranial pathology and CSF obtained via neurosurgical procedure or fluoroscopic guidance were excluded from the study group. Given no clear definition of traumatic LP in the literature, the incidence of traumatic LP was calculated using a cutoff of greater than 400 RBCs (visual threshold for bloody fluid) and 1,000 RBCs (arbitrary threshold selected by other authors) in CSF tube 1. Proportions were compared using chi-square statistics. Results: Seven hundred eighty-six CSF samples were recorded over one year. Twenty-four samples were obtained from patients with intracranial pathology or were obtained via a neurosurgical procedure. Of the remaining 762 CSF samples in the study population, 119 (15.6%) were traumatic using a cutoff of 400 RBCs, and 80 (10.5%) were traumatic, using a cutoff of 1,000 RBCs in tube 1. Five hundred three LPs were done in the ED and 259 were attributed to all other locations in the hospital. Using a cutoff of 400 RBCs, the incidence of traumatic LP in the ED was 13.3%, compared with 20% in the rest of the hospital (p < 0.025). Similarly, using a cutoff of 1,000 RBCs, the incidence of traumatic LP in the ED was 8.9%, compared with 13.5% in the rest of the hospital (p = 0.1). The incidence of "champagne taps" (defined as zero RBCs in the first and last tubes) in the ED was 34.4%, compared with 24.3% in the rest of the hospital (p < 0.01). Conclusions: The incidence of traumatic lumbar puncture is approximately 15% using a cutoff of 400 RBCs and 10% using a cutoff of 1,000 RBCs. In this study, the rate of traumatic lumbar puncture was significantly less (with a cutoff of 400 RBCs) and the rate of champagne tap was significantly greater for LPs done in the ED compared with the rest of the hospital.

    Personality disorders in 545 patients with eating disorders

    EUROPEAN EATING DISORDERS REVIEW, Issue 2 2008
    *Article first published online: 5 DEC 200, Kristine Godt
    Abstract Objective Previous research on the prevalence of personality disorders in patients with eating disorders varies greatly in findings, but a general understanding seem to exist that personality disorders are rather common among eating-disordered patients. The present investigation is aimed at establishing the prevalence of DSM III-R or DSM IV personality disorders in a large population seeking treatment for eating disorders. Method Five hundred and forty-five patients with DSM IV- eating disorders have been evaluated using the structured clinical interview for DSM III-R or IV-Axis II and the eating disorder examination. Results The 29.5% of the population have one or more personality disorders according to DSM III-R or DSM IV criteria. Personality disorders, and specifically borderline personality disorder, are significantly more common in patients with bulimia nervosa. Discussion The proportion of eating-disordered patients with co-morbid personality disorder may not be as large as often found in studies. This challenges the understanding of a strong overall connection between the two groups of disorder; however, the connection seems to exist in subsets of eating disorder samples.

    Experiences of pregnancy-related body shape changes and of breast-feeding in women with a history of eating disorders

    EUROPEAN EATING DISORDERS REVIEW, Issue 2 2003
    Gunilla Larsson
    Abstract In spite of the growing problems of eating disorders in society, no publications have reported the cumulative prevalence of eating disorders among childbearing women. The condition may constitute a risk during pregnancy and the childbirth period. This study examined the frequency of self-reported eating disorder histories in women who had been delivered 3,7 months earlier as well as their experiences of body shape changes and breast feeding and the length of the breast-feeding periods. Five hundred and sixteen women were invited to participate, of whom 454 responded to a questionnaire (88 per cent). A history of an eating disorder was reported by 11.5 per cent of the respondents, with a predominance of younger women. Significantly fewer women among those reporting an eating disorder breast-fed their 3-month-old baby. However, no difference was seen regarding feelings related to the transformed body shape. Almost all women described such feelings as positive. Copyright © 2003 John Wiley & Sons, Ltd and Eating Disorders Association. [source]


    Circulating levels of copeptin, a novel biomarker, in lower respiratory tract infections

    EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 2 2007
    B. Müller
    Abstract Background, Vasopressin has haemodynamic as well as osmoregulatory effects, and reflects the individual stress response. Copeptin is cosynthesized with vasopressin, directly mirroring vasopressin levels, but is more stable in plasma and serum. Both levels are increased in patients with septic shock. Lower respiratory tract infections (LRTI) are a precursor of sepsis. Thus, we investigated circulating levels and the prognostic use of copeptin for the severity and outcome in patients with LRTI. Materials and methods, Five hundred and forty-five consecutive patients with LRTI and 50 healthy controls were evaluated. Serum copeptin levels were measured with a new chemiluminescens sandwich immunoassay. Results, Of the 545 patients, 373 had community-acquired pneumonia (CAP), 60 acute exacerbations of chronic obstructive pulmonary disease (COPD), 59 acute bronchitis, 13 exacerbations of asthma and 40 other final diagnoses. Copeptin levels were significantly higher in patients with LRTI as compared to controls (P < 0·001) with highest levels in patients with CAP. Copeptin levels increased with increasing severity of CAP, as classified by the pneumonia severity index (PSI) (P < 0·001). In patients who died, copeptin levels on admission were significantly higher as compared to levels in survivors [70·0 (28·8,149·0) vs. 24·3 (10·8,43·8) pmol L,1, P < 0·001]. The area under the receiver operating curve (AUC) for survival was 0·75 for copeptin, which was significantly higher as compared to C-reactive protein (AUC 0·61, P = 0·01), leukocyte count (AUC 0·59, P = 0·01) and similar to procalcitonin (AUC 0·68, P = 0·21). Conclusions, Copeptin levels are increased with increasing severity of LRTI namely in patients with CAP and unfavourable outcome. Copeptin levels, as a novel biomarker, might be a useful tool in the risk stratification of patients with LRTI. [source]


    How are we doing with the treatment of essential tremor (ET)?

    EUROPEAN JOURNAL OF NEUROLOGY, Issue 6 2010
    Persistence of patients with ET on medication: data from 528 patients in three settings
    Background:, The pharmacological treatment of essential tremor (ET) is not optimal. There are only two first-line medications and troublesome side effects are common. It is not uncommon for patients to simply stop taking medication. Yet, no published data substantiate or quantify this anecdotal impression. Objectives:, To determine, amongst patients with ET who were prescribed medication for tremor, what proportion are still taking medication and what proportion have stopped? Methods:, Five hundred and twenty-eight patients with ET from three distinct study settings (clinical, brain donors, population) were interviewed. Results:, A clear pattern that emerged across settings was that the proportion of patients with ET who had stopped medication was sizable and consistently similar (nearly one-third): 31.4% (clinical), 24.3% (brain donors), 30.0% (population), 29.8% (overall). A similarly high proportion of cases with severe tremor had stopped their medication: 31.9% (clinical), 36.4% (brain donors). For the four most commonly used medications (propranolol, primidone, diazepam, topiramate), one-half or more of the treated patients had stopped the medication; amongst the less commonly used medications, the proportion who stopped was even higher. Conclusions:, Nearly one of every three patients with ET who had been prescribed medication for tremor had discontinued pharmacotherapy. Even more revealing was that a similar proportion of cases with severe tremor had stopped medication. These data make tangibly evident that there is a sizable population of patients with ET who are untreated and disabled, and underscore the inadequacy of current pharmacotherapeutic options for this common neurological disease.

    Health profiles and quality of life of 518 survivors of thyroid cancer

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 5 2003
    Pamela N. Schultz RN
    Abstract Background. Available literature describes the long-term outcome of thyroid cancer survivors with respect to thyroid cancer but not their overall medical and social well-being. Methods. Five hundred eighteen thyroid cancer survivors responded to a survey regarding medical and social impacts of their cancer experience. Results. All had surgery, and 417 (80.5%) also had some radiation. Two thirds (64.5%) reported that cancer created health effects varying by gender and passage of time; neurologic, musculoskeletal, and psychologic problems seemed most prominent. They reported more memory loss and psychologic problems than other cancer survivors and more migraine headaches than both other cancer survivors and the general population. Regarding family and work, they integrated well in society overall. However, unsolicited comments by 24.5% of responders disclosed symptoms reminiscent of thyroid hormone imbalance. Conclusion. Thyroid cancer survivors generally report good health long term but describe distinct, lasting medical problems including symptoms of thyroid dysregulation. The extent and manner in which cancer therapy contributes to the health profile of the group merits further inquiry. © 2003 Wiley Periodicals, Inc. Head Neck 25: 000,000, 2003 [source]


    Long-Term Migraine Prevention With Topiramate: Open-Label Extension of Pivotal Trials

    HEADACHE, Issue 7 2006
    Alan Rapoport MD
    Objective.,To demonstrate that topiramate is an effective and generally well-tolerated migraine preventive therapy when used for up to 14 months. Background.,Topiramate 100 and 200 mg/d significantly reduced mean monthly migraine frequency during 2 large, 26-week, randomized, placebo-controlled trials. Only a small number of clinical trials have examined the long-term (,1 year) effectiveness and safety of migraine preventive therapies. Methods.,Five hundred sixty-seven patients with an established history of migraine with or without aura were enrolled in this 8-month, open-label extension of 2 large (49 US and 52 US and Canadian medical centers), randomized, double-blind, placebo-controlled, parallel group, 26-week trials of identical design. To be eligible for the open-label extension, patients were required to have either completed the double-blind phase of the 2 pivotal migraine prevention trials or withdrew after 4 weeks due to lack of efficacy. All eligible patients, regardless of type or dose of study medication (topiramate or placebo) received in the double-blind phase, were titrated to a clinically effective dose of open-label topiramate based on physician judgment of patient response. Efficacy of topiramate was measured as the change in mean monthly migraine frequency. Results.,The mean topiramate dose during the open-label extension phase was 124.7 mg/d and 150.3 mg/d for patients on placebo (n = 159) or topiramate (n = 408), respectively, during the double-blind phase (N = 567, 91% female, mean age 39.4 years). Patients on topiramate for up to 14 months had 2.2 ± 2.4 (mean ± SD) migraines per month after completion of the open-label extension phase (3.4 ± 2.6 at double-blind endpoint). Patients on topiramate during the open-label extension phase only (placebo during the double-blind phase) had 3.0 ± 2.9 migraines per month at open-label extension endpoint (4.9 ± 3.0 migraines per month at double-blind endpoint). Discontinuation rates due to adverse events during the double-blind phase were 22.2% for patients on topiramate and 11.0% for patients on placebo. Discontinuation rates due to adverse events during the open-label extension phase were 8.6% for those patients who had already received topiramate during the double-blind phase and 20.9% for those patients who had previously received placebo. Conclusions.,Patients receiving topiramate experienced a sustained reduction in migraine frequency for up to 14 months. The effectiveness and safety of topiramate was consistent with that observed during 2 26-week pivotal trials. [source]


    Long-term follow-up of nevirapine-treated patients in a single-centre cohort

    HIV MEDICINE, Issue 8 2009
    M Colafigli
    Objectives We reviewed the safety and efficacy of nevirapine (NVP)-based therapy in all patients initiating NVP-containing combined antiretroviral therapy [cART (,3 drugs)] in our clinic since 1994. Methods Patient characteristics and laboratory values from the start of the NVP-based cART regimen to the last available follow-up or to NVP discontinuation were retrieved from an observational database. Results Five hundred and seventy-three patients were treated with NVP-based cART for a median of 18.4 (range 0.1,128.8) months. The 1-year cumulative estimated probability of discontinuing NVP-containing regimens for toxicity was 0.203. Only 1.9% developed a grade 3 alanine aminotransferase (ALT) elevation. Significant increases in high-density lipoprotein cholesterol were observed up to month 12 except in treatment-naïve patients, where the increase was limited to 3 months. Discontinuation because of cutaneous reaction was predicted independently by female gender [Hazard Ratio (HR) 3.21, P<0.001] and Centers for Disease Control class C (HR 0.50, P=0.012). Discontinuation because of liver toxicity was predicted independently by anti-hepatitis C virus positivity (HR 3.84, P<0.001). In patients starting NVP-containing cART with undetectable viral loads, the 5-year estimated probability of viral load >400 HIV-1 RNA copies/mL was 0.34. Conclusions Long-term follow-up with an NVP-containing cART showed a low rate of discontinuation caused by liver toxicity and the maintenance of virological suppression in patients switched with undetectable viral loads.

    Mining an Ostrinia nubilalis midgut expressed sequence tag (EST) library for candidate genes and single nucleotide polymorphisms (SNPs)

    INSECT MOLECULAR BIOLOGY, Issue 6 2008
    B. S. Coates
    Abstract Genes expressed in lepidopteran midgut tissues are involved in digestion and Bacillus thuringiensis (Bt) toxin resistance traits. Five hundred and thirty five unique transcripts were annotated from 1745 high quality O. nubilalis larval midgut expressed sequence tags (ESTs). Full-length cDNA sequence of 12 putative serine proteinase genes and 3 partial O. nubilalis aminopeptidase N protein genes, apn1, apn3, and apn4, were obtained, and genes may have roles in plant feeding and Bt toxin resistance traits of Ostrinia larvae. The EST library was not normalized and insert frequencies reflect transcript levels under the initial treatment conditions and redundancy of inserts from highly expressed transcripts allowed prediction of putative single nucleotide polymorphisms (SNPs). Ten di-, tri- or tetranucleotide repeat unit microsatellite loci were identified, and minisatellite repeats were observed within the C-termini of two encoded serine proteinases. Molecular markers showed polymorphism at 28 SNP loci and one microsatellite locus, and Mendelian inheritance indicated that markers were applicable to genome mapping applications. This O. nubilalis larval midgut EST collection is a resource for gene discovery, expression information, and allelic variation for use in genetic marker development. [source]


    Suicidal ideation among elderly homecare patients

    INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 1 2007
    Patrick J. Raue
    Abstract Objectives To identify the prevalence, correlates, and one-year naturalistic course of suicidal ideation in a representative sample of elderly adults newly admitted to visiting nurse homecare. Method Five hundred and thirty-nine participants (aged ,65), newly initiating homecare for skilled nursing services, were interviewed with the Structured Clinical Interview for DSM-IV (SCID-IV) and measures of depression severity, medical comorbidity, functional status, and social support. Participants were classified as having no suicidal ideation in the past month, passive ideation, active ideation, or active ideation with poor impulse control or suicide plan. Results Fifty-seven participants (10.6%) reported passive and six (1.2%) reported active suicidal ideation. Higher depression severity, greater medical comorbidity, and lower subjective social support were independently associated with the presence of any level of suicidal ideation. At one year, suicidal ideation persisted for 36.7% of those with ideation at baseline, and the incidence of suicide ideation was 5.4% Conclusions The high prevalence, persistence, and incidence of suicidal ideation in medically ill home healthcare patients underscore the relevance of this population for suicide prevention efforts. The clinical and psychosocial factors associated with suicidal ideation in this underserved, high-risk population are potentially modifiable, and thus useful targets for suicide prevention interventions.

    Accuracy of Spirometry in Diagnosing Pulmonary Restriction in Elderly People

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 11 2009
    Simone Scarlata MD
    OBJECTIVES: To compare the accuracy of a diagnosis of pulmonary restriction made using forced vital capacity (FVC) less than the lower limit of normal (LLN) with the criterion standard diagnosis made using total lung capacity (TLC) less than the LLN in an elderly population. DESIGN: Retrospective analysis. SETTING: A teaching hospital. PARTICIPANTS: Five hundred sixty-four ambulatory and acute care hospital patients aged 65 to 96 underwent complete pulmonary function evaluation. MEASUREMENTS: Sensitivity, specificity, positive and negative predictive values (PPV, NPV) of diagnosis of pulmonary restriction defined as FVC less than the LLN were calculated in the overall sample and after stratification according to bronchial obstruction. Expected PPV and NPV at different background prevalence of true pulmonary restriction (5% and 15%) were calculated using the Bayes theorem. RESULTS: Low sensitivity (0.32) and high specificity (0.95) were found, with an area under the receiver operating characteristic curve (AUC) of 0.89. In participants without bronchial obstruction, specificity was even higher, although sensitivity decreased to 0.28 (AUC=0.92). The PPV was good (0.81), whereas with a low to moderate a priori probability (prevalence from 5% to 15%) the NPV was fair (,0.89). CONCLUSION: A reduction in FVC below LLN cannot reliably identify true pulmonary restriction in elderly people, confirming previous findings in the adult population. Normal FVC, instead, can effectively exclude pulmonary restriction regardless of the presence of bronchial obstruction when the a priori probability is low or moderately high. [source]


    Clinical Features to Identify Urinary Tract Infection in Nursing Home Residents: A Cohort Study

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 6 2009
    (See editorial comments by Lindsay Nicolle on pp 111, 1114)
    OBJECTIVES: To identify clinical features associated with bacteriuria plus pyuria in noncatheterized nursing home residents with clinically suspected urinary tract infection (UTI). DESIGN: Prospective, observational cohort study from 2005 to 2007. SETTING: Five New Haven, Connecticut area nursing homes. PARTICIPANTS: Five hundred fifty-one nursing home residents each followed for 1 year for the development of clinically suspected UTI. MEASUREMENTS: The combined outcome of bacteriuria (>100,000 colony forming units from urine culture) plus pyuria (>10 white blood cells from urinalysis). RESULTS: After 178,914 person-days of follow-up, 228 participants had 399 episodes of clinically suspected UTI with a urinalysis and urine culture performed; 147 episodes (36.8%) had bacteriuria plus pyuria. The clinical features associated with bacteriuria plus pyuria were dysuria (relative risk (RR)=1.58, 95% confidence interval (CI)=1.10,2.03), change in character of urine (RR=1.42, 95% CI=1.07-1.79), and change in mental status (RR=1.38, 95% CI=1.03,1.74). CONCLUSION: Dysuria, change in character of urine, and change in mental status were significantly associated with the combined outcome of bacteriuria plus pyuria. Absence of these clinical features identified residents at low risk of having bacteriuria plus pyuria (25.5%), whereas presence of dysuria plus one or both of the other clinical features identified residents at high risk of having bacteriuria plus pyuria (63.2%). Diagnostic uncertainty still remains for the vast majority of residents who meet only one clinical feature. If validated in future cohorts, these clinical features with bacteriuria plus pyuria may serve as an evidence-based clinical definition of UTI to assist in management decisions. [source]


    The Relationship of Indwelling Urinary Catheters to Death, Length of Hospital Stay, Functional Decline, and Nursing Home Admission in Hospitalized Older Medical Patients

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 2 2007
    Jayna M. Holroyd-Leduc MD
    OBJECTIVES: To determine the association between indwelling urinary catheterization without a specific medical indication and adverse outcomes. DESIGN: Prospective cohort. SETTING: General medical inpatient services at a teaching hospital. PARTICIPANTS: Five hundred thirty-five patients aged 70 and older admitted without a specific medical indication for urinary catheterization. INTERVENTION: Indwelling urinary catheterization within 48 hours of admission. MEASUREMENTS: Death, length of hospital stay, decline in ability to perform activities of daily living (ADLs), and new admission to a nursing home. RESULTS: Indwelling urinary catheters were placed in 76 of the 535 (14%) patients without a specific medical indication. Catheterized patients were more likely to die in the hospital (6.6% vs 1.5% of those not catheterized, P=.006) and within 90 days of hospital discharge (25% vs 10.5%, P<.001); the greater risk of death with catheterization persisted in a propensity-matched analysis (hazard ratio (HR)=2.42, 95% confidence interval (CI)=1.04,5.65). Catheterized patients also had longer lengths of hospital stay (median, 6 days vs 4 days; P=.001); this association persisted in a propensity-matched analysis (HR=1.46, 95% CI=1.03,2.08). Catheterization was not associated (P>.05) with decline in ADL function or with admission to a nursing home. CONCLUSION: In this cohort of older patients, urinary catheterization without a specific medical indication was associated with greater risk of death and longer hospital stay. [source]


    Self-Reported Sleep and Nap Habits and Risk of Falls and Fractures in Older Women: The Study of Osteoporotic Fractures

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 8 2006
    Katie L. Stone PhD
    OBJECTIVES: To test the association between self-reported sleep and nap habits and risk of falls and fractures in a large cohort of older women. DESIGN: Study of Osteoporotic Fractures prospective cohort study. SETTING: Clinical centers in Baltimore, Maryland; Minneapolis, Minnesota; Portland, Oregon; and the Monongahela Valley, near Pittsburgh, Pennsylvania. PARTICIPANTS: Eight thousand one hundred one community-dwelling Caucasian women aged 69 and older (mean 77.0). MEASUREMENTS: Sleep and nap habits were assessed using a questionnaire at the fourth clinic visit (1993/94). Fall frequency during the subsequent year was ascertained using tri-annual questionnaire. Incident hip and nonspinal fractures during 6 years of follow-up were confirmed using radiographic reports. RESULTS: Five hundred fifty-three women suffered hip fractures, and 1,938 suffered nonspinal fractures. In multivariate models, women who reported napping daily had significantly higher odds of suffering two or more falls during the subsequent year (odds ratio=1.32, 95% confidence interval (CI)=1.03,1.69) and were more likely to suffer a hip fracture (hazard ratio (HR)=1.33, 95% CI=0.99,1.78) than women who did not nap daily. Those sleeping at least 10 hours per 24 hours had a higher risk of nonspinal fracture than (HR=1.26, 95% CI=1.00,1.58) and a similar but nonsignificant increased risk of hip fracture to (HR=1.43, 95% CI=0.95,2.15) those who reported sleeping between 8 and 9 hours. CONCLUSION: Self-reported long sleep and daily napping are associated with greater risk of falls and fractures in older women. Interventions to improve sleep may reduce their risk of falls and fractures. Future research is needed to determine whether specific sleep disorders contribute to these relationships. [source]


    Risk Factors for Surgical Site Infections in Older People

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 3 2006
    Keith S. Kaye MD
    OBJECTIVES: To identify risk factors for surgical site infection (SSI) in older people and to test a priori hypotheses regarding particular variables and SSI risk. DESIGN: Case-control study. SETTING: Duke University Medical Center and seven community hospitals in North Carolina and Virginia. PARTICIPANTS: Elderly patients (,65) who underwent surgery between 1991 and 2002 at the study hospitals. Cases were elderly patients with SSI; controls were elderly operative patients without SSI. Infection control practitioners prospectively identified patients. MEASUREMENTS: Data were collected retrospectively. Case patients who developed SSI were compared with control patients who did not develop SSI. RESULTS: Five hundred sixty-nine SSI cases were identified, and 589 uninfected controls were selected. In multivariate analysis, independent predictors of SSI included obesity (odds ratio (OR)=1.77, 95% confidence interval (CI)=1.34,2.32), chronic obstructive pulmonary disease (COPD) (OR=1.66, 95% CI=1.17,2.34), and a wound class classified as contaminated or dirty (OR=1.65, 95% CI=1.01,2.72). Having private insurance was associated with lower risk (OR=0.29, 95% CI=0.12,0.68). CONCLUSION: This study identified several independent predictors of SSI in older people, including comorbid conditions (COPD and obesity), perioperative variables (wound class), and socioeconomic factors (private insurance, which was associated with lower risk). The results from this study can be used to design and implement interventions for SSI prevention in high-risk older people. [source]


    Patterns and Predictors of Smoking Cessation in an Elderly Cohort

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 3 2006
    Heather E. Whitson MD
    OBJECTIVES: To identify subject characteristics that predict smoking cessation and describe patterns of cessation and recidivism in a cohort of elderly smokers. DESIGN: Prospective cohort study. SETTING: Piedmont region, North Carolina. PARTICIPANTS: Five hundred seventy-three subjects enrolled in the North Carolina Established Populations for Epidemiologic Studies of the Elderly who responded "yes" to question 179 on the baseline survey (Do you smoke cigarettes regularly now?) and survived at least 3 years, until the next in-person follow-up (1989/90). Subjects were classified as quitters (n=100) or nonquitters (n=473) based on subsequent smoking behavior. MEASUREMENTS: Reported smoking behavior, demographic characteristics of the smokers at baseline or subsequent interviews, 7-year mortality. RESULTS: After controlling for all characteristics studied, subjects who quit smoking were more likely to be female (P=.03) and showed a trend toward greater likelihood of a recent cancer diagnosis (P=.11). Recidivism was observed in only 16% (19/119) of subjects who reported no smoking in 1989/90. The percentage of subjects who died during 7 years of follow-up was 44.0% of quitters, compared with 51.6% of nonquitters. Smoking cessation was not associated with a statistically significant decrease in risk of death after controlling for other variables (odds ratio=0.78, 95% confidence interval=0.48,1.26). CONCLUSION: Smoking cessation in this elderly cohort was associated with different subject characteristics from those that predict successful cessation in younger populations, suggesting that older smokers may have unique reasons to stop smoking. Further study is needed to assess potential motives and benefits associated with smoking cessation at an advanced age. [source]


    The Association Between Obesity and the Frailty Syndrome in Older Women: The Women's Health and Aging Studies

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 6 2005
    Caroline S. Blaum MD
    Objectives: To determine whether obesity is associated with the frailty phenotype and, if so, whether comorbid conditions or inflammatory markers explain this association. Design: Cross-sectional analysis of baseline data from the Women's Health and Aging Studies I (1992) and II (1994), complementary population-based studies. Setting: Twelve contiguous ZIP code areas in Baltimore, Maryland. Participants: Five hundred ninety-nine community-dwelling women aged 70 to 79 with a body mass index (BMI) greater than 18.5 kg/m2. Measurements: The dependent variables were the frailty syndrome, including prefrailty, defined as presence of one or two of five frailty indicators (weakness, slowness, weight loss, low physical activity, exhaustion), and frailty, defined as three or more indicators. Independent variables included BMI, categorized using World Health Organization criteria as normal (18.5 to <25 kg/m2), overweight (25 to <30 kg/m2), and obese (,30 kg/m2); chronic diseases; C-reactive protein; and serum carotenoids. Results: Being overweight was significantly associated with prefrailty, and obesity was associated with prefrailty and frailty. In all frail women, regardless of BMI group, a similar pattern of three defining frailty indicators was found: slowness, weakness, and low activity (with the addition of weight loss in the normal weight group.) In multinomial regression models, obesity was significantly associated with prefrailty (odds ratio (OR)=2.23, 95% confidence interval (CI)=1.29,3.84) and frailty (OR=3.52, 95% CI=1.34,9.13), even when controlling for covariates. Conclusion: Obesity is associated with the frailty syndrome in older women in cross-sectional data. This association remains significant even when multiple conditions associated with frailty are considered. Prospective studies are needed to confirm this finding. [source]


    Older Women and HIV: How Much Do They Know and Where Are They Getting Their Information?

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 9 2004
    Susan J. Henderson MD
    Objectives: To assess older urban women's knowledge about sexual transmission of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) and to evaluate the relationship between their HIV/AIDS knowledge level and sources of information. Design: Cross-sectional survey conducted between June 2001 and July 2002. Trained research assistants administered a questionnaire in a face-to-face interview. Setting: General medicine clinic in a large public hospital in a high HIV/AIDS incidence area. Participants: Five hundred fourteen women aged 50 and older. Measurements: Nine questions assessing knowledge of risk of HIV sexual transmission with potential scores ranging from 0 to 9 correct answers. Participants identified all sources of HIV information. Results: The mean knowledge score was 3.7 out of a possible 9 correct responses (range 0 (3%) to 8 (1%)). Younger age, employment, and higher educational level were associated with higher knowledge scores, whereas marital status was unrelated. No respondent correctly answered all of the nine questions. The most commonly identified sources of HIV/AIDS information were television (85%), friends (54%), and newspapers (51%). Only 38% of respondents identified health professionals as a source of information about HIV/AIDS. Health professionals, newspapers, and family members were each independently associated with higher knowledge scores (P<.05). Conclusion: Older women in a general medicine clinic had limited knowledge of sexual transmission of HIV. HIV/AIDS education specifically targeted to this subpopulation is warranted, and health professionals may have an important role in disseminating such messages. [source]


    Patients with Hip Fracture: Subgroups and Their Outcomes

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 7 2002
    Elizabeth A. Eastwood PhD
    OBJECTIVES: To present several alternative approaches to describing the range and functional outcomes of patients with hip fracture. DESIGN: Prospective study with concurrent medical records data collection and patient and proxy interviews at the time of hospitalization and 6 months later. SETTING: Four hospitals in the New York metropolitan area. PARTICIPANTS: Five hundred seventy-one hospitalized adults aged 50 and older with hip fracture between July 1997 and August 1998. MEASUREMENTS: Rates of return to function in four physical domains, mortality, and nursing home residence at 6 months. Cluster analysis was used to describe the heterogeneity among the sample and identify variations in 6-month mortality, nursing home residence, and level of functioning and to develop a patient classification tree with associated patient outcomes at 6 months postfracture. RESULTS: In locomotion, transfers, and self-care, 33% to 37% of patients returned to their prior level of function by 6 months, including those needing assistance, but only 24% were independent in locomotion at 6 months. Cluster analysis identified eight patient subgroups that had distinct baseline features and variable outcomes at 6 months. The patient classification tree used four variables: atypical functional status (independent in locomotion but dependent in other domains); nursing home residence; independence/dependence in self-care; and age younger than 85 or 85 and older that identified five subgroups with variable 6-month outcomes that clinicians may use to predict likely outcomes for their patients. CONCLUSION: Patients with hip fracture are heterogeneous with respect to baseline and outcome characteristics. Clinicians may be better able to give patients and caregivers information on expected outcomes based on presenting characteristics used in the classification tree. [source]


    Chronic pain after cardiac surgery: a prospective study

    ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2010
    K. H. GJEILO
    Background: Chronic pain is a complication of several surgical procedures. The prevalence of chronic pain reported after cardiac surgery varies from 18% to 61%. However, most studies are retrospective, do not use validated instruments for pain measurement or include only pain at the sternum site. The aim of the present study was to assess chronic pain and health-related quality of life (HRQOL) after cardiac surgery. Methods: In a prospective, population-based study, we included 534 patients (413 males) and assessed chronic pain and HRQOL before, 6 months after, and 12 months after cardiac surgery. Pain was measured by the Brief Pain Inventory, while HRQOL was measured by the Short-Form 36 (SF-36). Results: Five hundred and twenty-one patients were alive 12 months after surgery; 462 (89%) and 465 (89%) responded after 6 and 12 months, respectively. Chronic pain was reported by 11% of the patients at both measurements. Younger age was associated with chronic pain [odds ratio 0.7 (95% confidence interval: 0.5,0.9)] at 12 months. Patients with chronic pain reported lower scores on seven of eight SF-36 subscales. Discussion: In conclusion, we observed a lower prevalence of chronic pain after cardiac surgery than in previous studies. Still, more than one out of 10 patients reported chronic pain after cardiac surgery. Chronic pain appears to affect HRQOL. Thus, given the large number of patients subjected to cardiac surgery, this study confirms that chronic pain after cardiac surgery is an important health care issue. [source]


    A Short-Term, Randomized, Double-Blind, Parallel-Group Study to Evaluate the Efficacy and Safety of Dronedarone versus Amiodarone in Patients with Persistent Atrial Fibrillation: The DIONYSOS Study

    JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 6 2010
    JEAN-YVES LE HEUZEY M.D.
    Dronedarone versus Amiodarone in Patients with AF.,,Introduction: We compared the efficacy and safety of amiodarone and dronedarone in patients with persistent atrial fibrillation (AF). Methods: Five hundred and four amiodarone-naïve patients were randomized to receive dronedarone 400 mg bid (n = 249) or amiodarone 600 mg qd for 28 days then 200 mg qd (n = 255) for at least 6 months. Primary composite endpoint was recurrence of AF (including unsuccessful electrical cardioversion, no spontaneous conversion and no electrical cardioversion) or premature study discontinuation. Main safety endpoint (MSE) was occurrence of thyroid-, hepatic-, pulmonary-, neurologic-, skin-, eye-, or gastrointestinal-specific events, or premature study drug discontinuation following an adverse event. Results: Median treatment duration was 7 months. The primary composite endpoint was 75.1 and 58.8% with dronedarone and amiodarone, respectively, at 12 months (hazard ratio [HR] 1.59; 95% confidence interval [CI] 1.28,1.98; P < 0.0001), mainly driven by AF recurrence with dronedarone compared with amiodarone (63.5 vs 42.0%). AF recurrence after successful cardioversion was 36.5 and 24.3% with dronedarone and amiodarone, respectively. Premature drug discontinuation tended to be less frequent with dronedarone (10.4 vs 13.3%). MSE was 39.3 and 44.5% with dronedarone and amiodarone, respectively, at 12 months (HR = 0.80; 95% CI 0.60,1.07; P = 0.129), and mainly driven by fewer thyroid, neurologic, skin, and ocular events in the dronedarone group. Conclusion: In this short-term study, dronedarone was less effective than amiodarone in decreasing AF recurrence, but had a better safety profile, specifically with regard to thyroid and neurologic events and a lack of interaction with oral anticoagulants.

    Loss of molars in periodontally treated patients: a retrospective analysis five years or more after active periodontal treatment

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 1 2006
    Bettina Dannewitz
    Abstract Objectives: Evaluation of tooth loss in molars and prognostic factors for molar survival. Material and Methods: Five hundred and five molars in 71 patients (mean age 46 years; 40 females) were evaluated. The following inclusion criteria were required: periodontal therapy of at least one molar, at least 5 years of supportive periodontal therapy, and baseline assessment of furcation involvement (FI). Results: At baseline 200 of 505 molars exhibited no FI, 116 degree I, 122 degree II, and 67 degree III FI. Twenty-seven molars did not receive periodontal treatment; 127 molars were subjected to non-surgical therapy, and 227 to flap surgery. Tunnel preparation was performed on 14 molars, root resection on 20, regenerative therapy on 57 teeth, and 33 molars were extracted. During the average follow-up period of 107 months 38 molars were lost additionally. Molars with degree III FI had the highest mortality. A multi-level proportional hazard model revealed smoking, baseline bone loss, number of molars left, and degree III FI as risk factors influencing the retention time of molars. Conclusion: Overall periodontal therapy results in a good prognosis of molars. Degree III FI leads to a significant deterioration of prognosis. Beyond FI smoking, baseline bone loss, and number of molars left influence molar survival. [source]


    Using iron deficiency tests for colorectal cancer screening: a feasibility study in one UK general practice

    JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 3 2004
    Adrian Edwards PhD MRCGP MRCP
    Abstract Iron deficiency is common at presentation in colorectal cancer. Testing for it may complement other screening tests such as faecal occult blood testing and sigmoidoscopy. We therefore examined the feasibility of offering iron deficiency testing to patients in a primary care setting in the UK, offering testing to all 1240 patients aged 55,74 years in one general practice in South Wales, UK. Patients with abnormal results were assessed and offered further investigations. Five hundred and fifty-one people (44.4%) attended for iron deficiency blood tests, of whom 26 patients (4.7%) were iron deficient and offered endoscopic assessment. This identified two cases of benign neoplasia amenable to treatment and no cases of cancer. Iron deficiency testing in a screening context appeared feasible although uptake may be low. [source]


    Risk of gastric cancer is not increased after partial gastrectomy

    JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 7 2000
    R Bassily
    Abstract Background: It has been suggested that there is an increased risk of gastric cancer following partial gastrectomy. This question has not been studied in an Australian population. Methods: The records of a total of 569 patients who had a partial gastrectomy for peptic ulcer disease at Repatriation General Hospital, Heidelberg, between 1957 and 1976 were reviewed. All were followed to date of death or 31 December 1996. The expected rate of gastric cancer for this population was estimated from published Australian age-and sex-specific gastric cancer mortality rates over this period, and a standardized incidence ratio was calculated. Results: The mean age at surgery was 53.5 years (range 27,83 years). There were 547 male (96.4%) and 22 female (3.6%) patients. Five hundred and seven (83.5%) had a Billroth II procedure. Thirty-eight patients (6.3%) were lost to follow up and were not included in the analysis. From the records of the Department of Veterans' Affairs, it was established that 125 (20.6%) were alive in December 1996, a mean survival after surgery of 18.8 years. The mean documented duration of follow up was 17.3 years (range 1,41 years). Nine patients developed cancer in the gastric remnant. The expected number of cancers in this population was 6.5. Assuming all survivors were free of gastric cancer, the standardized incidence ratio was 1.39 (95% confidence intervals 0.64,2.65, P = 0.313). Conclusion: The risk of gastric cancer was not increased after partial gastrectomy in this Australian population. [source]


    Detection of unusual rotavirus genotypes G8P[8] and G12P[6] in South Korea

    JOURNAL OF MEDICAL VIROLOGY, Issue 1 2008
    Van Phan Le
    Abstract Five hundred four fecal specimens, collected between 2004 and 2006 from young children with acute diarrhea, were screened for rotavirus by ELISA with VP6-specific antibody. Of these samples, 394 (78.2%) were confirmed as group A rotavirus and they underwent G- and P typing using a combination of ELISA, RT-PCR, and sequence analysis methods. The dominant circulating G serotype was G1 (35.6%) followed by G3 (26.4%), G4 (14.7%), and G2 (11.9%). There was a low prevalence of G9 (1.0%) and of unusual G type rotavirus, in particular, G12 (0.5%) and G8 (0.3%). Of the P genotype rotavirus in circulation, P[8] (53.0%) was most common followed by P[6] (15.5%), P[4] (15.2%), and P[9] (2.3%). Determination of G- and P type combinations revealed that G1P[8] strains were most prevalent (25.4%), amid G3P[8] (16.8%), G2P[4] (6.3%), and G4P[6] (6.1%) strains. Unusual or rare combinations such as G2P[6], G2P[8], G3P[4], G2P[9], G1P[9], G3P[9], G12P[6], G1P[4], G3P[6], and G8P[8] were also found. Owing to the recent emergence of G8 and G12 rotavirus, the findings from this study are important since they provide new information concerning the local and global spread of rotavirus genotypes. J.

    Is Gadolinium Enhancement Predictive of the Development of Brain Atrophy in Multiple Sclerosis?

    JOURNAL OF NEUROIMAGING, Issue 4 2002
    A Review of the Literature
    ABSTRACT Background and Purpose. Several studies have demonstrated that brain atrophy can be detected over relatively short intervals from the earliest stages of multiple sclerosis (MS). Reviewing the published data, the authors highlight some hypothetical pathological mechanisms proposed as determinants of brain atrophy. Methods. Using the terms multiple sclerosis, MRI (magnetic resonance imaging), and brain atrophy, 181 citations were identified. The authors considered only studies with prospective designs with natural-course MS patients and/or placebo-treated patients of therapeutic trials, in which patients under-went baseline and follow-up scans with a T1-weighted gadolinium diethylenetriamine penta-acetic acid sequence (0.1 mmol/kg body weight), and correlation analyses between Gd enhancement activity and brain atrophy progression. Results. Five hundred thirty-two patients of 5 natural history studies and 5 therapeutic trial studies participated in the review process. The main observation was that in patients with a relapsing-remitting (RR) disease course, there was a correlation between Gd enhancement activity and brain atrophy progression. This correlation was not influenced by any other demographic and clinical additional data considered in the review process. Conclusions. Examination of the pathological mechanisms pro-posed in the reviewed studies led the authors to believe that inflammation is only in part responsible for the development of brain atrophy. This conclusion may have an implication for the strategies of tissue protection advocated in the early stages of the RR course and strengthen recent evidence indicating that anti-inflammatory immunomodulatory agents and immunosuppressive treatments, which predominantly act against the inflammatory component of disease activity, may not have similar effects on progressive tissue loss, either in RR or progressive MS.
