[source] The prevalence of lipodystrophy in an ambulant HIV-infected population: it all depends on the definitionHIV MEDICINE, Issue 3 2001VM Carter Objectives This study's objective was to determine the prevalence of body shape changes and metabolic abnormalities in an ambulant population with HIV infection. Three different definitions of lipodystrophy were used to assess these changes. Patients' anthropometric measures and dual-energy X-ray absorptiometry (DEXA) scans were compared in order to estimate fat distribution in this population. We sought to evaluate potential predictors for lipodystrophy according to each of the three definitions. Methods We performed a cross-sectional study in the outpatient clinic of a tertiary referral hospital in Melbourne, Australia. We enrolled a total of 167 HIV-infected ambulatory patients over 3 months in mid-1998. Data on 159 males, 149 of whom were receiving triple combination antiretroviral therapy, were evaluated. Anthropometric measures, clinical examination, self-report of body shape changes, biochemical measures and DEXA scan were used to assess lipodystrophy and risk factors for cardiovascular disease. Patients described body shape changes in the face, trunk, arms and legs. Laboratory parameters measured included fasting triglyceride (TG), cholesterol, high-density lipoproteins (HDL), glucose, insulin, CD4 cell count and plasma HIV RNA. Current and past antiretroviral therapies were ascertained. Results According to one proposed Australian national definition of lipodystrophy (LDNC), the prevalence of lipodystrophy in this population was 65%. This definition included an objective assessment with major and minor criteria. Patient-defined lipodystrophy (LDP), which involved a subjective assessment of thinning arms and legs and central adiposity, occurred in 19%. Patient-defined lipoatrophy (LAP), which involved a subjective assessment of thinning arms and legs without central adiposity, occurred in 21.3%. No change in body habitus was noted by 37% of the cohort. Hypercholesterolaemia was recorded in 44%, hypertriglyceridaemia in 52% and elevated insulin levels in 23%. Anthropometry was predictive of the per cent total body fat recorded by DEXA scan, but produced consistently lower values. In multivariate analysis, LDP and LAP were significantly associated with stavudine (d4T) use, while LAP was also associated with zidovudine (ZDV) treatment. There were no treatment associations with LDNC. Protease inhibitor (PI) exposure was associated with metabolic changes but not patient perceived body shape changes, while d4T and ZDV exposure was associated with increased triglycerides and reduced peripheral fat stores. Conclusions The prevalence of body shape changes in a single population varied depending on the definition applied. The LDNC definition overestimated body shape abnormalities in comparison with patient perception. LAP was associated with significantly lower fat stores measured by anthropometry and DEXA scan than those identified under the LDNC definition. In contrast to LDNC, LAP was associated with d4T exposure, nucleoside reverse transcriptase inhibitor (NRTI) and ZDV duration of use, but not PI use. Until a consensus definition for lipodystrophy is developed, including agreement on objective measurement and thresholds for abnormality, careful description of the individual components of the syndrome is required to enable cohort comparisons so that predictors of the syndrome can be assessed more accurately and outcome studies made feasible. [source] Effects of music listening on adult patients' pre-procedural state anxiety in hospitalINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 1 2008Elizabeth Gillen MSc Executive summary Background Anticipation of an invasive procedure in hospital is likely to provoke feelings of anxiety and stress in patients. An unfamiliar environment, loss of control, perceived or actual physical risk, dependence on strangers and separation from friends and family are all factors that can contribute to the development of such feelings. Recently, there has been considerable interest in the anxiolytic potential of music listening in a variety of clinical settings, yet thus far, little is known about the impact of music listening on the pre-procedural patient population. A systematic review of all literature to date was indicated to improve understanding of outcomes and impact of music listening on pre-procedural anxiety, thus helping nurses decide whether or not to incorporate music listening into practice and to highlight a need, or otherwise, for a related primary research agenda. Objective The objective of this review was to determine the best available evidence on the effectiveness of music listening in reducing adult hospital patients' pre-procedural state anxiety. Inclusion criteria Types of studies This review included randomised controlled trials and quasi-experimental research designs that examined the efficacy of music listening in reducing state anxiety among pre-procedural hospital patients published between January 1985 and February 2006. The search was limited to publications after 1985 to coincide with the increasing interest and use of complementary therapies within health care during the 1980s and 1990s. Types of participants Participants of interest to the review were adult day patients, ambulatory patients and inpatients who were about to undergo any type of clinical procedure. Types of intervention The review focused on studies that investigated pre-procedural music listening employed and prescribed as a potentially therapeutic activity. It excluded any other form of music therapy. Types of outcome measures The primary outcome measures examined were alterations in state anxiety and a variety of physiological variables such as blood pressure and respiration and heart rates. Search strategy A search for published and unpublished literature between January 1985 and February 2006 was conducted using all major electronic databases. A three-step search strategy was devised which consisted of using high-precision MeSH terminology and keywords to ensure that all material relevant to the review was captured. Critical appraisal The methodological quality of included studies was assessed by two reviewers, who appraised each study independently, using the standard Joanna Briggs Institute (JBI) critical appraisal tools. Data extraction and synthesis Data were extracted from the studies that were identified as meeting the criteria for methodological quality using a data-extraction tool developed for the review. Studies were grouped by outcome measure and summarised using tabular and narrative formats. Results The review demonstrated that state anxiety is defined and measured using both psychological and physiological parameters. Music listening had a consistently positive and statistically significant effect on reducing psychological parameters of pre-procedural state anxiety. However, the results from the measurement of various pre-procedural physiological parameters failed to reveal any consistent positive changes in patients who had listened to music. This calls into question the adequacy of the theories in this area which link anxiety and the automated and central nervous systems and the effect that music listening may have on these processes and physiological responses. Conclusions/implications for practice 1,In order to reduce anxiety, it is likely that patients will benefit psychologically from having the opportunity to listen to music in the immediate pre-procedural period. 2,Patients do not appear to experience any alteration in physiological status as a result of listening to music. 3,Further research is indicated in order to replicate existing studies, to strengthen the evidence to support such interventions and to establish intervention parameters. 4,Further research is needed analysing the physiological mechanisms by which music listening is believed to reduce state anxiety and the contribution of the automated and other nervous systems to this reduction.

A high prevalence of hypovitaminosis D in Finnish medical in- and outpatients. J Intern Med 2001; 249: 559,563. Objective.,To study the prevalence of hypovitaminosis D [serum 25(OH)D , 37 nmol L,1)] in Finnish medical in- and outpatients in a cross-sectional study. Methods.,The subjects were 106 consecutive medical inpatients (57 females, 49 males with mean ages of 65 and 58 years) from the Peijas Hospital, Vantaa, Finland, and 99 ambulatory patients (48 females, 51 males with mean ages of 42 and 46 years) contacting a private outpatient centre in Helsinki, Finland. Serum 25(OH)D, vitamin D binding protein (DBP), free vitamin D index (FDI), intact PTH (iPTH), and albumin-corrected calcium were measured. Results.,Serum 25-hydroxyvitamin D [25(OH)D] was 37 nmol L,1 or less in 70% of female and in 61% of male inpatients and in 44% of female and in 37% of male outpatients. In the whole population, a statistically significant inverse association (P < 0.0001) was detected between iPTH and 25(OH)D levels; the iPTH concentration appeared to start increasing when 25(OH)D concentration was 50 nmol L,1 or less. The association remained the same (P < 0.0001) when FDI was used instead of 25(OH)D in the calculations. When the sexes were analysed separately, the statistically significant association was found only in females (P < 0.0001 for iPTH versus 25(OH)D; P < 0.0001 for iPTH versus FDI) but not in males. Conclusion.,Hypovitaminosis D is very common amongst Finnish in- and outpatients in both sexes, causing secondary hyperparathyroidism in females. More extensive studies are warranted to elucidate the vitamin D status of the Finnish population. [source] Understanding and Treating Patients With Alcoholic Cirrhosis: An UpdateALCOHOLISM, Issue 7 2009Giovanni Addolorato Alcoholic cirrhosis represents the terminal stage of alcoholic liver disease (ALD) and one of the main causes of death among alcohol abusers. The aim of this review was to provide an update on alcoholic cirrhosis, with an emphasis on recent findings. Increased alcohol consumption in developing countries is expected to increase cirrhosis mortality. There is a need, therefore, to develop new approaches to the prevention of ALD, including more attention to co-factors that may increase risk of ALD (i.e., obesity and diabetes, chronic HCV infection, and smoking). Furthermore, a better understanding of the pathological mechanisms on the basis of alcohol cirrhosis represents a cornerstone in order to develop new pharmacological treatments. Inflammatory and immune responses along with oxidative stress and alterations in adipokine secretion might contribute in different ways to the evolution of alcohol-induced fibrosis/cirrhosis. As of this date, patients with severe alcoholic hepatitis with a Maddrey Discriminant Factor (MDF) 32 should be offered pentoxifylline and/or corticosteroids unless contraindications exist. For ambulatory patients, S-adenosylmethionine (SAMe) may be considered in a motivated patient with nutritional support. Current studies do not support use of anti-tumor necrosis factor (TNF)-alpha antibody. Finally, achieving total alcohol abstinence should represent the main aim in the management of patients affected by any stage of cirrhosis. In the last decades, several drugs able to increase abstinence and prevent alcohol relapse have been evaluated and some of them have obtained approval for alcohol dependence. Patients with alcoholic cirrhosis; however, are usually excluded from such treatments. A recent study demonstrated the efficacy and safety of baclofen in inducing and maintaining alcohol abstinence in cirrhotic alcohol-dependent patients with cirrhosis. All together the information available suggests the need of a multimodal approach in the clinical management of these patients. [source] Sleep-disordered breathing in a general heart failure population: relationships to neurohumoral activation and subjective symptomsJOURNAL OF SLEEP RESEARCH, Issue 1 2006ARCHANA RAO Summary The aim of this study was to determine the prevalence of sleep-related breathing disorders (SDB) in a UK general heart failure (HF) population, and assess its impact on neurohumoral markers and symptoms of sleepiness and quality of life. Eighty-four ambulatory patients (72 male, mean (SD) age 68.6 (10) yrs) attending UK HF clinics underwent an overnight recording of respiratory impedance, SaO2 and heart rate using a portable monitor (Nexan). Brain natriuretic peptide (BNP) and urinary catecholamines were measured. Subjective sleepiness and the impairment in quality of life were assessed (Epworth Sleepiness Scale (ESS), SF-36 Health Performance Score). SDB was classified using the Apnoea/Hypopnoea Index (AHI). The prevalence of SDB (AHI > 15 events h,1) was 24%, increasing from 15% in mild-to-moderate HF to 39% in severe HF. Patients with SDB had significantly higher levels of BNP and noradrenaline than those without SDB (mean (SD) BNP: 187 (119) versus 73 (98) pg mL,1, P = 0.02; noradrenaline: 309 (183) versus 225 (148) nmol/24 h, P = 0.05). There was no significant difference in reported sleepiness or in any domain of SF-36, between groups with and without SDB (ESS: 7.8 (4.7) versus 7.5 (3.6), P = 0.87). In summary, in a general HF clinic population, the prevalence of SDB increased with the severity of HF. Patients with SDB had higher activation of a neurohumoral marker and more severe HF. Unlike obstructive sleep apnoea, SDB in HF had little discernible effect on sleepiness or quality of life as measured by standard subjective scales. [source] Exploring the risk of diabetes mellitus and dyslipidemia among ambulatory users of atypical antipsychotics: a population-based comparison of risperidone and olanzapine,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 6 2005Jocelyne Moisan PhD Abstract Purpose To compare the incidence rates of diabetes mellitus and dyslipidemia in ambulatory first-time users of risperidone and olanzapine. Methods The database for the Prescription Drug Insurance Plan in the province of Quebec was used as the data source for a population-based cohort study. Denominalized data were extracted for all ambulatory patients who first received an atypical antipsychotic between 1 January 1997 and 31 August 1999. Eligible patients were categorized as taking: no antidiabetic medication; no lipid reducing medication; neither type of medication. Those who started to use an outcome drug (an antidiabetic or lipid-lowering medication) before the end of the follow-up period (31 August 2000) were considered to have developed the corresponding outcome disease. Incidence rate ratios (IRR) (and 95% confidence intervals) for initiating antihyperglycemic or lipid-lowering drug treatment, or both were calculated. Outcomes on risperidone were compared to those on olanzapine. Results A total of 19,582 eligible patients were included in the analysis. Relative to risperidone, olanzapine was associated with a higher risk of initiating a pharmacologic treatment for diabetes [IRR: 1.33 (1.03,1.74)], dyslipidemia [IRR: 1.49 (1.22,1.83)], or either condition [1.47 (1.23,1.76)]. Conclusions Olanzapine seems to be associated with a higher risk of developing diabetes and/or dyslipidemia than risperidone. Further prospective studies are needed to rigorously assess the safety of olanzapine. Copyright © 2005 John Wiley & Sons, Ltd. [source] ORIGINAL RESEARCH,ENDOCRINE: Pattern of Endocrinal Changes in Patients with Sexual DysfunctionTHE JOURNAL OF SEXUAL MEDICINE, Issue 4 2005Ahmed I. El-Sakka MD ABSTRACT Introduction., Many patients with endocrinal changes (endocrinopathy) have some degrees of sexual dysfunction that necessitate assessment and treatment. Aim., To assess the prevalence, and identify the pattern, of endocrinopathy in patients with sexual dysfunction in our community. Methods., A total of 1,248 male patients with sexual dysfunction were enrolled in this study. Patients were screened for erectile dysfunction (ED) and sexual desire by the erectile function and the sexual desire domains of the International Index of Erectile Function (IEEF). Patients underwent routine laboratory investigations as well as total testosterone and prolactin assessment. All patients were referred to an endocrinologist for clinical and biochemical assessment of their endocrine function. The evaluation consisted of comprehensive history taking, physical examination, and, as needed, laboratory investigations. Results., Mean ages ± SD were 51.9 ± 12.2 and 52.3 ± 11.7 years for patients with and without endocrinopathy, respectively. Of the study population, 23.8% had endocrinopathy. The most frequent endocrinal changes were low testosterone level (15%), hyperprolactinemia (13.7%), and hypothyroidism (3.1%). There were significant associations between endocrinopathy and obesity, smoking, low desire, and premature ejaculation (P < 0.05 for each). Also, significant associations were found between low desire and low testosterone level, hyperprolactinemia, and hypothyroidism (P < 0.05 for each). Hyperprolactinemia was significantly associated with premature ejaculation (P < 0.05) but not with low testosterone level (P > 0.05). There was no significant association between endocrinopathy and age, cigarette smoking (number and duration), and ED (duration, severity, type of onset, and progression) (P > 0.05 for each). Conclusion., Endocrinopathy is not a rare condition among ambulatory patients with sexual dysfunction. This study provides a quantitative estimate of endocrinopathy in ambulatory patients with sexual dysfunction. [source] Decline in rheumatoid vasculitis prevalence among US veterans: A retrospective cross-sectional studyARTHRITIS & RHEUMATISM, Issue 9 2009Christie Bartels Objective To examine trends in the prevalence of rheumatoid vasculitis in a national US population comprising both hospitalized and ambulatory patients with rheumatoid arthritis (RA). Methods In this serial cross-sectional study, we analyzed data on hospitalized and ambulatory patients spanning 22 years (1985,2006) and 10 years (1997,2006), respectively, to determine the prevalence of rheumatoid vasculitis, as defined by the International Classification of Diseases, Ninth Revision. Our search encompassed data collected on a predominantly male study population during 10 million hospitalizations and outpatient visits, and included annual data on >37,000 RA patients. To test for a decrease in rheumatoid vasculitis prevalence, breakpoint analysis was performed using stepwise Chow and Durbin-Watson tests. Results There was a clear decline in the prevalence of rheumatoid vasculitis, and this decline remained evident even after accounting for a decreased number of hospitalizations among RA patients. Peak prevalence occurred among hospitalized patients in the 1980s, and prevalence gradually declined throughout the 1990s. Furthermore, simultaneous breakpoints representing a significant drop in rheumatoid vasculitis prevalence between the years 2000 and 2001 were demonstrated for both inpatients (P < 0.000) and outpatients (P < 0.003). The prevalence of vasculitis dropped 53% among inpatients and 31% among outpatients between 2000 and 2001. Conclusion Our results demonstrate a significant decline in rheumatoid vasculitis prevalence after 2000 in this nationwide sample of hospitalized and ambulatory patients. The clear, consistent drop in prevalence provides an opportunity for the formulation of causal hypotheses, including consideration of the impact of biologic agents used to treat RA, on rheumatoid vasculitis. [source] Bridging of Chronic Oral Anticoagulation with Enoxaparin in Patients with Atrial Fibrillation: Results from the Prospective BRAVE RegistryCARDIOVASCULAR THERAPEUTICS, Issue 4 2009C. Hammerstingl Current American College of Chest Physicians (ACCP) guidelines on the perioperative management of oral anticoagulation (OAC) suggest bridging therapy with therapeutic doses of low-molecular-weight heparin (LMWH) in patients with atrial fibrillation (AF) if at high or moderate thromboembolic (TE) risk, and with reduced doses in patients with low TE risk. Our objective was to assess the efficacy and safety of bridging OAC with enoxaparin in AF patients. These are the results of an open, prospective monocenter register. Hospitalized and ambulatory patients with AF requiring bridging therapy at high or moderate TE risk and normal renal function were treated with therapeutic LMWH doses; all other patients received reduced doses. A total of 703 patients were enrolled, of whom 358 (50.9%) were at moderate-to-high and 345 (49.1%) at low TE risk. Renal impairment was detected in 308 patients (43.8%). One hundred ninety patients (27.1%) were treated with therapeutic LMWH doses and 513 (72.9%) with reduced doses. No TE events were observed during the follow-up period (0%; 95% confidence interval [CI] 0.0,0.52). Three major bleeds (0.4%; 0.1,1.2) and 60 minor bleeds were noted (8.9%; 6.6,10.9). Age and total LMWH doses were risk factors for bleeding in the multivariate analysis. The study, under conditions of everyday clinical care, supports a predefined bridging regimen based on the individual patient's TE risk and renal function. Patients with low TE risk or with impaired renal function can be bridged effectively and safely with reduced LMWH doses. [source] |
