Pain in Multiple System Atrophy a Systematic Review and Meta-Analysis.

Background: Individuals with multiple system atrophy (MSA) often complain about pain, nonetheless this remains a poorly investigated non-motor feature of MSA. Objectives: Here, we aimed at assessing the prevalence, characteristics, and risk factors for pain in individuals with MSA. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines, we systematically screened the PubMED, Cochrane, and Web of Science databases for papers published in English until September 30, 2022, combining the following keywords: "pain," "multiple system atrophy," "MSA," "olivopontocerebellar atrophy," "OPCA," "striatonigral degeneration," "SND," "Shy Drager," and "atypical parkinsonism." Results: The search identified 700 records. Sixteen studies provided information on pain prevalence in cohorts of MSA individuals and were included in a qualitative assessment based on the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool. Thirteen studies (11 cross-sectional, two longitudinal) scored ≥14 points on QUADAS assessment and were included in a quantitative analysis, pooling data from 1236 MSA individuals. The resulting pooled prevalence of pain in MSA was 67% (95% confidence intervals [CI] = 57%-75%), and significantly higher in individuals with MSA of parkinsonian rather than cerebellar type (76% [95% CI = 63%-87%] vs. 45% [95% CI = 33%-57%], P = 0.001). Pain assessment tools and collected information were highly heterogeneous across studies. Two studies reported pain treatment strategies and found that only every second person with MSA complaining about pain had received targeted treatment. Conclusions: We found that pain is a frequent, but still under-recognized and undertreated feature of MSA. Further research is needed to improve pain detection and treatment in MSA.

Cardiac catherization in Austria : Results from the Austrian National Cardiac Catheterization Laboratory Registry (ANCALAR) 2012-2018.

BACKGROUND: Cardiac catheterization is one of the most widely performed cardiac interventional procedures worldwide. The Austrian National Catheterization Laboratory Registry (ANCALAR), started in 1992, collects annual data on cardiac catheterization in Austria. The registry enables in-depth understanding of the dynamics of cardiac catheterization procedures and their use across 34 cardiac catheterization laboratories in Austria. METHODS: Data from ANCALAR on cardiac catheterization including the latest data for 2017, voluntarily provided by centers with cardiac catheterization laboratories, were analyzed. Where possible, international comparisons in therapeutic and interventional cardiac procedures are made with Switzerland and Germany. RESULTS: Internationally, Austria ranks alongside the top countries in Europe. Whilst the number of people undergoing routine percutaneous coronary interventions (PCI) remains stable, complex and acute interventions are increasing year by year in Austria. CONCLUSION: Evidence from ANCALAR revealed that Austria is another example of the difficulties of weighing current guidelines with new emerging evidence and resulting real-life clinical practice in the dynamic world of interventional cardiology.

Austrian National CathLab Registry (ANCALAR): cardiac catheterization, coronary angiography (CA), and percutaneous coronary intervention (PCI) in Austria during the year 2011 (Registry Data with Audit including 2012).

Concerning international comparison for the year 2011, Austria is situated under the top nations with 6,383 diagnostic coronary angiographies (CA), 2,407 percutaneous coronary interventions (PCI), and 47 transarterial aortic valve implantations (TAVI) per 1 million inhabitants in Europe. Although the number of TAVI increases rapidly since its first introduction in 2007 (47 TAVI per 1 million inhabitants in 2011, not including surgical cases from the transapical route), the data for CA and PCI remained constant during the past years.The rates of stent (91%) and drug-eluting stent implantations (78% of stents) also remained constant on a high level. Little fluctuation is also reflected in the complication data (including mortality evaluation). An increased morality is well known, especially in patients with the so-called ST-segment elevation myocardial infarction and consecutive shock (19-35% in the past years).The application of certain special devices increased (clot catcher) or decreased (glycoprotein IIb/IIIa receptor antagonist) in 2011 or were finally unused (Laser).Interestingly, not only in Austria, it was observed several times that scientific knowledge, recommended as Class I Indications in the guidelines, takes several years to establish itself nationwide.Our independent, purely academic activity is located in the area of health services research, and has also the option to generate benchmarks for individual centers. Participation in our surveys is voluntary. Since 1992, every year, without interruption (no missing center!), 90-100 parameters are applicable. The questionnaire will be optimized and adapted to current conditions. This is done in cooperation with the participating centers. To provide comparability, we make only minimal and absolutely most necessary modifications.The data are collected and summarized at the end of the year by each center itself. During the year, the centers are visited to perform audits and to keep personal contact to them.The data for 2011 were presented in Linz (November 23, 2012) at the autumn meeting of the working group "Interventional Cardiology of the Austrian Society of Cardiology" (ÖKG), as a basis for discussion. The presentation can be viewed by using private access code to the ÖKG video presentation page ( http://oekg.medroom.at/ ); the publication will also be placed under the website http://iik.i-med.ac.at.

[Heart rate and functional impairment are predictors of outcome in heart failure patients in the real world. Data from the Austrian Heart Failure registry]. / Ruhepuls und funktionelle Einschränkungen als prognostische Parameter bei herzinsuffizienten Patienten im tatsächlichen Leben. Daten aus dem Herzinsuffizienz-Register der ÖKG.

PURPOSE: Elevated heart rate (70 beats per minute-bpm or more) is a predictor of impaired prognosis in patients with ischemic heart failure. The Austrian Working Group on Heart Failure has established a registry in May 2006 for all patients referred to dedicated heart failure clinics with a planned follow-up after 12 ± 3 months. Here we report an analysis of the prognostic impact of elevated heart rate at referral in a well-defined cohort of heart failure patients. METHODS: Between May 2006 and October 2009 1904 patients have been documented in the Austrian Heart Failure Registry. One thousand threehundred and sixty three patients (72%) had sinus rhythm at referral. Kaplan-Meier and Cox proportional hazards regression analyses were used to compare overall and cardiovascular mortality between high (70 bpm or more) and low heart-rate groups. Patients who were lost-to-follow-up (n = 166) were censored at the time of last contact. RESULTS: At baseline in 793 patients (58%) heart rate has been elevated (70 bpm or more) while in 562 patients it has been below 70 bpm, in 8 patients no baseline heart rate has been recorded. Groups were equally balanced regarding age, gender and cardiovascular risk factors with the exception of smokers (more active smokers in the high heart-rate group: 23 vs 14%; p = 0.001) and valvular cause of heart failure (more frequent in the high heart-rate group: 3% vs 1%; p = 0.012). Patients in the high heart-rate group had significantly higher median NT-pro-BNP (1470 pg/ml, IQR 499-4188 pg/ml) compared to patients in the low heart-rate group (784 pg/ml, IQR 314-2162 pg/ml; p < 0.001). NYHA functional classes III and IV have been more frequent in the high heart-rate group than in the low heart-rate group (32% and 22%, respectively; p < 0.001) while reduced left ventricular ejection fraction (39% or less) has been more frequent in the high heart-rate group than in the low heart-rate group (71% and 61%, respectively; p < 0.001). In the high heart-rate group treatment with beta-blockers has been less frequent than in the low heart rate group (76% and 86%, respectively; p < 0.01) while dosage of beta-blocker therapy has been comparable in both groups. Of the 75 patients who died within 3.5 years 38 deaths had a cardiovascular cause. Cox proportional hazards analysis revealed that high NYHA functional class (III and IV) and elevated heart rate (70 bpm or more) were the best predictors of overall mortality while cardiovascular mortality could best be predicted by NYHA functional classes III and IV. CONCLUSION: Higher NYHA-functional classes and elevated heart rate are predictors of adverse outcome in chronic heart failure patients.

Antibody dynamics and spontaneous viral clearance in patients with acute hepatitis C infection in Rio de Janeiro, Brazil.

BACKGROUND: The anti-HCV antibody response has not been well characterized during the early phase of HCV infection and little is known about its relationship to the clinical course during this period. METHODS: We analyzed serial anti-HCV antibodies longitudinally obtained from a prospective cohort of 65 patients with acute HCV infection by using a microparticle enzyme immunoassay AxSYM HCV 3.0 (Abbott Diagnostics) during the first 12 months from HCV acquisition in Rio de Janeiro, Brazil. Spontaneous viral clearance (SVC) was defined as undetectable HCV RNA in serum, in the absence of treatment, for three consecutive HCV PCR tests within 12-months of follow-up. RESULTS: Baseline antibody values were similar among patient groups with self-limiting HCV evolution (n = 34) and persistent viremia (n = 31) [median (interquartile range) signal/cut-off ratio (s/co) 78.7 (60.7-93.8) vs. 93.9 (67.8-111.9), p = 0.26]. During 12-months follow-up, patients with acute spontaneous resolving HCV infection showed significantly lower serial antibody response in comparison to individuals progressing to chronic infection [median (interquartile range) s/co 62.7 (35.2-85.0) vs. 98.4 (70.4-127.4), p < 0.0001]. In addition, patients with self-limiting HCV evolution exhibited an expeditious, sharp decline of serial antibody values after SVC in comparison to those measured before SVC [median (interquartile range) s/co 56.0 (25.4-79.3) vs. 79.4 (66.3-103.0), p < 0.0001]. CONCLUSION: Our findings indicate a rapid short-term decline of antibody values in patients with acute spontaneous resolving HCV infection.

Primary percutaneous intervention of ST-elevation myocardial infarction in Austria: Results from the Austrian acute PCI registry 2005-2007.

BACKGROUND: Primary percutaneous coronary intervention (PPCI) has become the preferred reperfusion strategy in ST-elevation myocardial infarction (STEMI). Implementation of networks of care and registries providing continuous quality assessment are key components for optimal management in patients with STEMI. AIM: To analyze procedural success and in-hospital outcome of interventional therapy of STEMI in Austria. METHODS: We evaluated a total number of 4016 consecutive STEMI patients registered in the first three years after implementation of the Austrian acute PCI registry in January 2005. RESULTS: The rate of PPCI as an indication for acute coronary intervention increased from 83.5% in 2005 to 92.4% in 2007 (P < 0.0001). During this period the median door-to-balloon time decreased from 60.0 (40.0-90.0) min to 53.0 (30.0-80.0) min (P = 0.012). The percentage of patients receiving adequate adjunctive antithrombotic therapy with ASA/heparin and clopidogrel significantly increased (78.8-85.1% and 67.8-90.3%, respectively; P < 0.001). Overall in-hospital mortality was 9.6% in rescue PCI, 6.4% in facilitated PCI and 5.1% in PPCI. On multivariate analysis, cardiogenic shock (OR: 20.21, 95% CI: 12.21-33.44, P < 0.001), resuscitation (OR: 2.62, 95% CI: 1.47-4.69, P = 0.01), age (OR: 1.04, 95% CI: 1.02-1.06, P < 0.001) and angiographic success (OR: 5.93, 95% CI: 3.33-10.57, P < 0.001) were independent predictors of in-hospital death. CONCLUSION: Continuous nationwide efforts to establish regional networks for STEMI treatment in the years 2005-2007 led to a decrease in door-to-balloon time, improved adjunctive antithrombotic therapy and an in-hospital mortality of 5%. Results of interventional STEMI treatment in Austria are in accordance with current guidelines and with other contemporary registries.

Use of penalized splines in extended Cox-type additive hazard regression to flexibly estimate the effect of time-varying serum uric acid on risk of cancer incidence: a prospective, population-based study in 78,850 men.

PURPOSE: We sought to investigate the effect of serum uric acid (SUA) levels on risk of cancer incidence in men and to flexibly determine the shape of this association by using a novel analytical approach. METHODS: A population-based cohort of 78,850 Austrian men who received 264,347 serial SUA measurements was prospectively followed-up for a median of 12.4 years. Data were collected between 1985 and 2003. Penalized splines (P-splines) in extended Cox-type additive hazard regression were used to flexibly model the association between SUA, as a time-dependent covariate, and risk of overall and site-specific cancer incidence and to calculate adjusted hazard ratios with their 95% confidence intervals. RESULTS: During follow-up 5189 incident cancers were observed. Restricted maximum-likelihood optimizing P-spline models revealed a moderately J-shaped effect of SUA on risk of overall cancer incidence, with statistically significantly increased hazard ratios in the upper third of the SUA distribution. Increased SUA (>/=8.00 mg/dL) further significantly increased risk for several site-specific malignancies, with P-spline analyses providing detailed insight about the shape of the association with these outcomes. CONCLUSIONS: Our study is the first to demonstrate a dose-response association between SUA and cancer incidence in men, simultaneously reporting on the usefulness of a novel methodological framework in epidemiologic research.
