Systematic review of dexketoprofen in acute and chronic pain

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Background: Dexketoprofen, an NSAID used in the management of acute and chronic pains, is licensed in several countries but has not previously been the subjected of a systematic review. We used published and unpublished information from randomised clinical trials (RCTs) of dexketoprofen in painful conditions to assess evidence on efficacy and harm. Methods: PubMed and Cochrane Central were searched for RCTs of dexketoprofen for pain of any aetiology. Reference lists of retrieved articles and reviews were also searched. Menarini Group produced copies of published and unpublished studies (clinical trial reports). Data were abstracted into a standard form. For studies reporting results of single dose administration, the number of patients with at least 50 % pain relief was derived and used to calculate the relative benefit (RB) and number-needed-to-treat (NNT) for one patient to achieve at least 50 % pain relief compared with placebo. Results: Thirty-five trials were found in acute pain and chronic pain; 6,380 patients were included, 3,381 receiving dexketoprofen. Information from 16 trials (almost half the total patients) wa

Circulating microRNAs in sera correlate with soluble biomarkers of immune activation but do not predict mortality in ART treated individuals with HIV-1 infection: A case control study

Introduction: The use of anti-retroviral therapy (ART) has dramatically reduced HIV-1 associated morbidity and mortality. However, HIV-1 infected individuals have increased rates of morbidity and mortality compared to the non-HIV-1 infected population and this appears to be related to end-organ diseases collectively referred to as Serious Non-AIDS Events (SNAEs). Circulating miRNAs are reported as promising biomarkers for a number of human disease conditions including those that constitute SNAEs. Our study sought to investigate the potential of selected miRNAs in predicting mortality in HIV-1 infected ART treated individuals. Materials and Methods: A set of miRNAs was chosen based on published associations with human disease conditions that constitute SNAEs. This case: control study compared 126 cases (individuals who died whilst on therapy), and 247 matched controls (individuals who remained alive). Cases and controls were ART treated participants of two pivotal HIV-1 trials. The relative abundance of each miRNA in serum was measured, by RTqPCR. Associations with mortality (all-cause, cardiovascular and malignancy) were assessed by logistic regression analysis. Correlations between miRNAs and CD4+ T cell count, hs-CRP, IL-6 and D-dimer were also assessed. Results: None of the selected miRNAs was associated with all-cause, cardiovascular or malignancy mortality. The levels of three miRNAs (miRs -21, -122 and -200a) correlated with IL-6 while miR-21 also correlated with D-dimer. Additionally, the abundance of miRs -31, -150 and -223, correlated with baseline CD4+ T cell count while the same three miRNAs plus miR- 145 correlated with nadir CD4+ T cell count. Discussion: No associations with mortality were found with any circulating miRNA studied. These results cast doubt onto the effectiveness of circulating miRNA as early predictors of mortality or the major underlying diseases that contribute to mortality in participants treated for HIV-1 infection

Development and Validation of a Risk Score for Chronic Kidney Disease in HIV Infection Using Prospective Cohort Data from the D:A:D Study

Ristola M. on työryhmien DAD Study Grp ; Royal Free Hosp Clin Cohort ; INSIGHT Study Grp ; SMART Study Grp ; ESPRIT Study Grp jäsen.Background Chronic kidney disease (CKD) is a major health issue for HIV-positive individuals, associated with increased morbidity and mortality. Development and implementation of a risk score model for CKD would allow comparison of the risks and benefits of adding potentially nephrotoxic antiretrovirals to a treatment regimen and would identify those at greatest risk of CKD. The aims of this study were to develop a simple, externally validated, and widely applicable long-term risk score model for CKD in HIV-positive individuals that can guide decision making in clinical practice. Methods and Findings A total of 17,954 HIV-positive individuals from the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) study with >= 3 estimated glomerular filtration rate (eGFR) values after 1 January 2004 were included. Baseline was defined as the first eGFR > 60 ml/min/1.73 m2 after 1 January 2004; individuals with exposure to tenofovir, atazanavir, atazanavir/ritonavir, lopinavir/ritonavir, other boosted protease inhibitors before baseline were excluded. CKD was defined as confirmed (>3 mo apart) eGFR In the D:A:D study, 641 individuals developed CKD during 103,185 person-years of follow-up (PYFU; incidence 6.2/1,000 PYFU, 95% CI 5.7-6.7; median follow-up 6.1 y, range 0.3-9.1 y). Older age, intravenous drug use, hepatitis C coinfection, lower baseline eGFR, female gender, lower CD4 count nadir, hypertension, diabetes, and cardiovascular disease (CVD) predicted CKD. The adjusted incidence rate ratios of these nine categorical variables were scaled and summed to create the risk score. The median risk score at baseline was -2 (interquartile range -4 to 2). There was a 1: 393 chance of developing CKD in the next 5 y in the low risk group (risk score = 5, 505 events), respectively. Number needed to harm (NNTH) at 5 y when starting unboosted atazanavir or lopinavir/ritonavir among those with a low risk score was 1,702 (95% CI 1,166-3,367); NNTH was 202 (95% CI 159-278) and 21 (95% CI 19-23), respectively, for those with a medium and high risk score. NNTH was 739 (95% CI 506-1462), 88 (95% CI 69-121), and 9 (95% CI 8-10) for those with a low, medium, and high risk score, respectively, starting tenofovir, atazanavir/ritonavir, or another boosted protease inhibitor. The Royal Free Hospital Clinic Cohort included 2,548 individuals, of whom 94 individuals developed CKD (3.7%) during 18,376 PYFU (median follow-up 7.4 y, range 0.3-12.7 y). Of 2,013 individuals included from the SMART/ESPRIT control arms, 32 individuals developed CKD (1.6%) during 8,452 PYFU (median follow-up 4.1 y, range 0.6-8.1 y). External validation showed that the risk score predicted well in these cohorts. Limitations of this study included limited data on race and no information on proteinuria. Conclusions Both traditional and HIV-related risk factors were predictive of CKD. These factors were used to develop a risk score for CKD in HIV infection, externally validated, that has direct clinical relevance for patients and clinicians to weigh the benefits of certain antiretrovirals against the risk of CKD and to identify those at greatest risk of CKD.Peer reviewe

Nested PCR detection of Theileria equi infection and frequency in horses imported into Mexico

The purpose of this study was to assess the frequency of Theileria equi in horses imported into Mexico. During different stages of quarantine, 348 blood samples were taken from clinically healthy horses imported into Mexico from 2011 to 2013. Nested PCR (nPCR) of the Merozoite Antigen-1 (EMA-1) gene was performed for pathogen detection. In total, 93 horses tested positive for T. equi resulting in a 26.72% frequency with a 95% Confidence Interval (CI) of 22.07-31.37%. This is the first molecular diagnostics study to identify T. equi-positive horses imported into Mexico these results highlight the importance of nPCR analysis for T. equi in clinically healthy imported horses. © Medwell Journals, 2014

De onde vem o endividamento feminino?: construção e validação de um modelo PLS-PM Where does the women debt come from?: construction and validation of a PLS-PM model

O consumo exacerbado pode levar muitos indivíduos a contraírem dívidas comprometendo uma parcela significativa de suas rendas e, em muitos casos, acabando por ser tornarem inadimplentes. A inadimplência trás consigo efeitos muitas vezes arrasadores tanto do ponto de vista macroeconômico, aumentando o risco das operações e produtos financeiros, como do ponto de vista do indivíduo, ao afetar suas relações sociais, seu estado psicológico e sua vida familiar. Por outro lado, a maior participação da mulher no mercado de trabalho trouxe uma maior independência financeira e consequentente maior poder na decisão de consumo e ao mesmo tempo, maiores responsabilidades sobre o gerenciamento financeiro e nas decisões de endividamento. Neste sentido, este estudo centrou-se na identificação e análise dos fatores que afetam na propensão ao endividamento, nas mulheres da Mesorregião Centro Ocidental Rio-grandense. Assim, este trabalho propõe um modelo estrutural para explorar as relações entre os fatores determinantes da propensão ao endividamento junto às mulheres da referida Mesorregião, considerando variáveis que compõem os construtos de STATUS SOCIAL, PREOCUPAÇÃO, ESTABILIDADE, PRAZER, PODER, ORÇAMENTO, ILUSÃO e MATERIALISMO. Para isso, foram aplicados 2.500 questionários espalhados estatisticamente entre os 31 municípios que compõem esta Mesorregião. Os dados foram analisados através da metodologia Partial Least Squares - Path Modeling (PLS-PM). Sumariamente, os resultados sugerem que o construto ENDIVIDAMENTO está associado aos construtos STATUS, PREOCUPAÇÃO e MATERIALISMO, corroborando com as teorias das Finanças Comportamentais, ao sugerir que as decisões que envolvem endividamento vão além da simples relação consumo e renda, ou seja, existem outras variáveis comportamentais que são importantes na hora do indivíduo contrair dívidas, tais como, o significado que o indivíduo atribui ao dinheiro e o nível de materialismo.<br>The exacerbate consumption may lead many individuals to contract debts which commite a significant portion of their income and, in many cases, eventually taking into default. The default often brings with it devastating effects in both macroeconomic point of view, increasing the risk of operations and financial products, such as from the individual standpoint, affecting his social, psychological state and family life. Moreover, the bigger women participation in labor market brought greater financial independence and empowerment in decision and consequently larger power of consumption decision and at the same time, more responsibility on financial management and borrowing decisions. Thus, this study focused on the identification and analysis of factors which affect the indebtedness propensity, among women in the Rio Grande do Sul western-central mesoregion. This study proposes a structural model to determine the relationships among the women indebtedness propensity determinants of that mesoregion, considering variables which compose the constructs of SOCIAL STATUS, CONCERN, STABILITY, PLEASURE, POWER, BUDGET, ILLUSION and MATERIALISM. For this, were applied 2,500 questionnaires statistically scattered among the 31 cities which compose the mesoregion. Data were analyzed by Partial Least Squares -Path Modeling (PLS-PM) methodology. In summary, the results suggest that the construct INDEBTEDNESS is associated with SOCIAL STATUS, CONCERN and MATERIALISM, corroborating with the Behavioral Finance theories, suggesting that decisions involving borrowing go beyond the simple consumption and income relationship, i.e., there are other behavioral variables which are important in the time that individual contract debts, such as the meaning that the individual attaches to money and the materialism level

Metamizole-associated adverse events: a systematic review and meta-analysis.

BACKGROUND Metamizole is used to treat pain in many parts of the world. Information on the safety profile of metamizole is scarce; no conclusive summary of the literature exists. OBJECTIVE To determine whether metamizole is clinically safe compared to placebo and other analgesics. METHODS We searched CENTRAL, MEDLINE, EMBASE, CINAHL, and several clinical trial registries. We screened the reference lists of included trials and previous systematic reviews. We included randomized controlled trials that compared the effects of metamizole, administered to adults in any form and for any indication, to other analgesics or to placebo. Two authors extracted data regarding trial design and size, indications for pain medication, patient characteristics, treatment regimens, and methodological characteristics. Adverse events (AEs), serious adverse events (SAEs), and dropouts were assessed. We conducted separate meta-analyses for each metamizole comparator, using standard inverse-variance random effects meta-analysis to pool the estimates across trials, reported as risk ratios (RRs). We calculated the DerSimonian and Laird variance estimate T2 to measure heterogeneity between trials. The pre-specified primary end point was any AE during the trial period. RESULTS Of the 696 potentially eligible trials, 79 trials including almost 4000 patients with short-term metamizole use of less than two weeks met our inclusion criteria. Fewer AEs were reported for metamizole compared to opioids, RR = 0.79 (confidence interval 0.79 to 0.96). We found no differences between metamizole and placebo, paracetamol and NSAIDs. Only a few SAEs were reported, with no difference between metamizole and other analgesics. No agranulocytosis or deaths were reported. Our results were limited by the mediocre overall quality of the reports. CONCLUSION For short-term use in the hospital setting, metamizole seems to be a safe choice when compared to other widely used analgesics. High-quality, adequately sized trials assessing the intermediate- and long-term safety of metamizole are needed
