ABSTRACT
The Magic Touch sirolimus-coated balloon (SCB) was recently introduced in Europe and features robust clinical technology different from other devices on the market. This device is able to deliver a sufficient sirolimus dose to the target segment to reduce neointimal proliferation with very little exposure downstream and no apparent adverse effects at sustained high drug concentrations. The SCB represents a promising novelty within the drug-coated balloon arena due to its mid-term efficacy and safety in the treatment of coronary artery disease, especially in de novo and small-vessel coronary lesions. The purpose of this article is to provide an up-to-date overview of the currently available animal and clinical trial results, as well as to highlight ongoing trials on the Magic Touch SCB.
Among modern drug-coated balloons, Magic Touch features Nanolutè technology, which allows effective and rapid sirolimus release and retention for 812 weeks. Previous and ongoing trials are showing good clinical performance with sustained safety.
ABSTRACT
Percutaneous coronary intervention (PCI) with drug-eluting stents (DES) represents the treatment of choice for the majority of patients with coronary artery disease. While currently available DES, in addition to physiological support, has failed to show the non-inferiority to coronary artery bypass grafting (CABG) in terms of cumulative incidence of clinical events over the short-term follow-up. Studies have also shown that DES is associated with an increased risk of target vessel revascularization compared to CABG after long-term follow-up. Drug-coated balloons (DCB) have been shown to provide clinically significant benefits in the management of in-stent restenosis and diffuse coronary artery disease, as well as small coronary artery lesions. The aim of this review was to describe the inherent technical limitations of DES and highlight the potential advantages of PCI with DCB for long-term outcomes and potentially demonstrate its non-inferiority to CABG. Currently, ongoing studies will provide more information and help to understand if a blended therapy of DCB+DES can match the performance of CABG in the need for revascularization in more complex patients.
ABSTRACT
Contexto y objetivo: las anomalías hematológicas se encuentran entre las complicaciones más comunes de la infección por el VIH. También se han realizado bastantes estudios sobre las alteraciones en el perfil de lípidos, aunque los resultados en gran medida no han sido concluyentes. El presente estudio se llevó a cabo para evaluar el recuento de células CD4 y el perfil de lípidos en los pacientes infectados por el VIH y el SIDA en la población india y los correlaciona con los controles sero-negativos. Materiales y métodos: El presente estudio fue diseñado como un estudio transversal, con base en un hospital, para evaluar el recuento de células CD4 y el perfil de lípidos en los pacientes infectados por VIH y SIDA en la población india y los correlaciona con los controles sero-negativos. La evaluación del perfil de lípidos se realizó utilizando Erba EM 360, un analizador automático impulsado por un fotómetro de rejilla de difracción, mientras que los recuentos de células CD4 se evaluaron utilizando el Contador de ciclo de Partec. Análisis estadístico utilizado: Los datos se analizaron con SPSS versión 15.0 (SPSS Inc., Chicago, IL, EE. UU.). La comparación de dichos parámetros se realizó mediante el análisis de varianza (ANOVA) y la prueba post-hoc de Games-Howell. Se consideró estadísticamente significativo un valor de p <0,05. Resultados: Los niveles de colesterol total y lipoproteínas de baja densidad (LDL) disminuyeron significativamente, mientras que los triglicéridos y las lipoproteínas de muy baja densidad (VLDL) aumentaron significativamente en los pacientes infectados por VIH y SIDA en comparación con los controles sero-negativos. Conclusión: El colesterol total, las LDL, los triglicéridos y las VLDL se alteraron significativamente en los pacientes infectados por VIH y con SIDA en comparación con los controles sero-negativos
Context and Aim: Hematological abnormalities are amongst the most common complications of infection with HIV.There have been quite a few studies on the alterations in lipid profile, too, though the results have largely been inconclusive. The present study was carried-out to assess CD4 cell counts and lipid profile in the HIV infected and AIDS patients in the Indian population and correlates them with the sero-negative controls. Materials and Methods: The present study was designed as a cross-sectional, hospital-based study to assess CD4 cell counts and lipid profile in the HIV infected and AIDS patients in the Indian population and correlates them with the sero-negative controls. Evaluation of lipid profile was done using Erba EM 360, an automated analyzer powered by a diffraction grating photometer while CD4 cell counts were evaluated using Partec Cyflow Counter. Statistical analysis used: The data was analyzed using SPSS version 15.0 (SPSS Inc., Chicago, IL, USA). Comparison of the said parameters was done using Analysis of Variance (ANOVA) and post-hoc Games-Howell test. p-value of <0.05 was considered statistically significant. Results: The levels of total cholesterol and low-density lipoproteins (LDLs) were significantly decreased while triglycerides and very low density lipoproteins (VLDLs) were significantly increased in the HIV infected and AIDS patients when compared with the sero-negative controls. Conclusion: Total cholesterol, LDLs, triglycerides and VLDLs were significantly altered in the HIV infected and AIDS patients when compared with the sero-negative controls

BACKGROUND: Recent studies have found that there is a strong association between ischemic heart disease (IHD) and hypertension (HTN) with spirometric indices. AIMS: To study the prevalence of obstructive airway disease (OAD) in non-smoker subjects with IHD and HTN and to compare them with healthy population. SETTINGS AND DESIGN: This was a prospective, case-control, and observational study. SUBJECTS AND METHODS: A total of 100 patients (cases) (n = 100) admitted in medicine department were recruited for this study. Controls (n = 100) were apparently healthy age- and sex-matched without HTN and IHD, recruited from March 2007 to July 2008. All eligible subjects were subjected to spirometric examination on a turbine-based spirometer (MIR spirolab-II) according to ATS/ERS guidelines. Forced expiratory volume/forced vital capacity (FEV(1)/FVC) ratio <70% was used to make a diagnosis of OAD. STATISTICAL ANALYSIS USED: All analyses were carried out using Statistical Software Package for Social Sciences trial version (SPSS 10 version). RESULTS: Out of 100 cases, 18 were with FEV(1)/FVC ratio <70% (OAD) and 82 had >70% FEV(1)/FVC ratio. Out of 100 controls, 2 were with FEV(1)/FVC ratio <70% (OAD) and 98 had >70% FEV(1)/FVC ratio. Eleven patients out of 66 from the case population with HTN had FEV(1)/FVC ratio <70% (Odds ratio 8.044). Prevalence of OAD in the hypertensive individuals was 16.66%. Twelve patients out of 62 from the case population with IHD had FEV(1)/FVC ratio <70% (Odds ratio of 9.333). Prevalence of OAD in the IHD individuals was 19.35%. In multiple correlation results for case population, when pulmonary function test variables were correlated with various dependant (age) and independent variables [HTN, IHD, height, weight, body mass index (BMI)], they were significantly reduced (P = 0.00017). In multivariate analysis (MANOVA), spirometric variables like FEV(1), FEV(1)/FVC%, FVC, forced expiratory flow (FEF) 25-75%, and peak expiratory flow rate (PEFR) were compared with factors like IHD, HTN, and covariates like age and BMI. We found that systolic blood pressure (SBP; P = 0.005), diastolic blood pressure (DBP; P = 0.05), height (P = 0.05), weight (P = 0.042), and IHD (P = 0.0001) were strongly associated with reduced pulmonary functions like FEV(1), FEV(1)/FVC%, and FVC. The presence of IHD and HTN were independently associated with the presence of OAD. CONCLUSIONS: This study highlights the increased prevalence of OAD amongst patients with IHD and HTN. Patients with IHD and HTN should routinely undergo inexpensive investigations like spirometry to detect the presence of underlying OAD.
