Spectral Analysis Related to Bare-Metal and Drug-Eluting Coronary Stent Implantation

Background: The autonomic nervous system plays a central role in cardiovascular regulation; sympathetic activation occurs during myocardial ischemia. Objective: To assess the spectral analysis of heart rate variability during stent implantation, comparing the types of stent. Methods: This study assessed 61 patients (mean age, 64.0 years; 35 men) with ischemic heart disease and indication for stenting. Stent implantation was performed under Holter monitoring to record the spectral analysis of heart rate variability (Fourier transform), measuring the low-frequency (LF) and high-frequency (HF) components, and the LF/HF ratio before and during the procedure. Results: Bare-metal stent was implanted in 34 patients, while the others received drug-eluting stents. The right coronary artery was approached in 21 patients, the left anterior descending, in 28, and the circumflex, in 9. As compared with the pre-stenting period, all patients showed an increase in LF and HF during stent implantation (658 versus 185 ms2, p = 0.00; 322 versus 121, p = 0.00, respectively), with no change in LF/HF. During stent implantation, LF was 864 ms2 in patients with bare-metal stents, and 398 ms2 in those with drug-eluting stents (p = 0.00). The spectral analysis of heart rate variability showed no association with diabetes mellitus, family history, clinical presentation, beta-blockers, age, and vessel or its segment. Conclusions: Stent implantation resulted in concomitant sympathetic and vagal activations. Diabetes mellitus, use of beta-blockers, and the vessel approached showed no influence on the spectral analysis of heart rate variability. Sympathetic activation was lower during the implantation of drug-eluting stents.

First- Versus Second-Generation Drug-Eluting Stents in Acute Coronary Syndromes (Katowice-Zabrze Registry)

Abstract Background: There are sparse data on the performance of different types of drug-eluting stents (DES) in acute and real-life setting. Objective: The aim of the study was to compare the safety and efficacy of first- versus second-generation DES in patients with acute coronary syndromes (ACS). Methods: This all-comer registry enrolled consecutive patients diagnosed with ACS and treated with percutaneous coronary intervention with the implantation of first- or second-generation DES in one-year follow-up. The primary efficacy endpoint was defined as major adverse cardiac and cerebrovascular event (MACCE), a composite of all-cause death, nonfatal myocardial infarction, target-vessel revascularization and stroke. The primary safety outcome was definite stent thrombosis (ST) at one year. Results: From the total of 1916 patients enrolled into the registry, 1328 patients were diagnosed with ACS. Of them, 426 were treated with first- and 902 with second-generation DES. There was no significant difference in the incidence of MACCE between two types of DES at one year. The rate of acute and subacute ST was higher in first- vs. second-generation DES (1.6% vs. 0.1%, p < 0.001, and 1.2% vs. 0.2%, p = 0.025, respectively), but there was no difference regarding late ST (0.7% vs. 0.2%, respectively, p = 0.18) and gastrointestinal bleeding (2.1% vs. 1.1%, p = 0.21). In Cox regression, first-generation DES was an independent predictor for cumulative ST (HR 3.29 [1.30-8.31], p = 0.01). Conclusions: In an all-comer registry of ACS, the one-year rate of MACCE was comparable in groups treated with first- and second-generation DES. The use of first-generation DES was associated with higher rates of acute and subacute ST and was an independent predictor of cumulative ST.

Nutrição mineral de leguminosas tropicais VII: recrutamento de micronutrientes pela cunhã (Clitoria ternatea L.)

Com a finalidade de obter dados acerca do recrutamento de micronutrientes, a leguminosa foi cultivada em um Latossolo Vermelho Escuro Orto, série "Luiz de Queiroz" em Piracicaba, SP. A coleta de amostras constituidas por plantas rasteiras, foi efetuada de 15 em 15 dias a partir dos 41 dias após a semeadura. Após cada amostragem, as plantas foram separadas em folhas, caules, flores e vagens. Em cada época nas diferentes partes da planta foram determinadas as concentrações de boro, cobre, ferro, manganês e zinco. Os autores consideram que: - O período de 86 dias após a semeadura, sob o ponto de vista dos minerais, é aquele para o aproveitamento da planta como forrageira; - Aos 86 dias após a germinação, a concentração dos micronutrientes na folha é de 41 ppm B; 8 ppm Xu; 402 ppm Fe; 94 ppm Mn e 45 ppm Zn; - Aos 86 dias após a germinação, o acumulo de micronutrientes por planta é de 390 mg B; 81 mg Cu; 3404 mg Fe; 751 mg Mn; 402 mg Zn; - Para uma população teórica de 825.000 plantas por hectare, a extração dos micronutrientes é na ordem de 322 g B; 67 g Cu; 2808 g Fe; 620 g Mn e 332 g de Zn.

Ecologia populacional de Aegla franciscana (Crustacea, Decapoda, Anomura) em São Francisco de Paula, RS, Brasil

A pesquisa teve como objetivos caracterizar aspectos populacionais de Aegla franciscana Buckup & Rossi, 1977 que ocorre em corpos d'água do planalto sul-rio-grandense, onde foram analisados a distribuição de freqüência em classes de tamanho, a proporção sexual, o período reprodutivo através da freqüência de fêmeas ovígeras, o recrutamento e a fecundidade da espécie. As amostragens foram realizadas sazonalmente, no arroio Rolante, município de São Francisco de Paula, RS. Os eglídeos foram coletados com puçás, medidos e devolvidos ao arroio. Foram amostrados 1.322 exemplares, sendo 567 machos, 579 fêmeas e 176 animais com sexo indefinido. Machos e fêmeas foram agrupados em classes de comprimento do cefalotórax (CC), onde foi observada distribuição bimodal. A amplitude do comprimento do cefalotórax dos machos variou de 3,86 mm a 22,09 mm e o das fêmeas de 4,06 mm a 22,48 mm, sendo que os machos apresentaram tamanho mediano (10,36 mm) superior ao das fêmeas (9,89 mm). A proporção sexual foi de 1:1 (chi2 = 0,03; p>0,05). Na análise da proporção sexual, por classes de tamanho, observou-se que os machos são mais freqüentes nas classes superiores e as fêmeas nas classes intermediárias. O primeiro registro do surgimento de juvenis na população ocorreu no verão e de fêmeas ovígeras no outono, estas ocorrendo mais freqüentemente no inverno. As fêmeas ovígeras produzem em média 123,3 ± 47,8 ovos; observou-se correlação entre o comprimento do cefalotórax das fêmeas ovígeras e o número de ovos (r = 0,81).

Results of An International Study of Quantitative BCR/ABL Assays Using Defined RNA Samples

Molecular monitoring of BCR/ABL transcripts by real time quantitative reverse transcription PCR (qRT-PCR) is an essential technique for clinical management of patients with BCR/ABL-positive CML and ALL. Though quantitative BCR/ABL assays are performed in hundreds of laboratories worldwide, results among these laboratories cannot be reliably compared due to heterogeneity in test methods, data analysis, reporting, and lack of quantitative standards. Recent efforts towards standardization have been limited in scope. Aliquots of RNA were sent to clinical test centers worldwide in order to evaluate methods and reporting for e1a2, b2a2, and b3a2 transcript levels using their own qRT-PCR assays. Total RNA was isolated from tissue culture cells that expressed each of the different BCR/ABL transcripts. Serial log dilutions were prepared, ranging from 100 to 10-5, in RNA isolated from HL60 cells. Laboratories performed 5 independent qRT-PCR reactions for each sample type at each dilution. In addition, 15 qRT-PCR reactions of the 10-3 b3a2 RNA dilution were run to assess reproducibility within and between laboratories. Participants were asked to run the samples following their standard protocols and to report cycle threshold (Ct), quantitative values for BCR/ABL and housekeeping genes, and ratios of BCR/ABL to housekeeping genes for each sample RNA. Thirty-seven (n=37) participants have submitted qRT-PCR results for analysis (36, 37, and 34 labs generated data for b2a2, b3a2, and e1a2, respectively). The limit of detection for this study was defined as the lowest dilution that a Ct value could be detected for all 5 replicates. For b2a2, 15, 16, 4, and 1 lab(s) showed a limit of detection at the 10-5, 10-4, 10-3, and 10-2 dilutions, respectively. For b3a2, 20, 13, and 4 labs showed a limit of detection at the 10-5, 10-4, and 10-3 dilutions, respectively. For e1a2, 10, 21, 2, and 1 lab(s) showed a limit of detection at the 10-5, 10-4, 10-3, and 10-2 dilutions, respectively. Log %BCR/ABL ratio values provided a method for comparing results between the different laboratories for each BCR/ABL dilution series. Linear regression analysis revealed concordance among the majority of participant data over the 10-1 to 10-4 dilutions. The overall slope values showed comparable results among the majority of b2a2 (mean=0.939; median=0.9627; range (0.399 - 1.1872)), b3a2 (mean=0.925; median=0.922; range (0.625 - 1.140)), and e1a2 (mean=0.897; median=0.909; range (0.5174 - 1.138)) laboratory results (Fig. 1-3)). Thirty-four (n=34) out of the 37 laboratories reported Ct values for all 15 replicates and only those with a complete data set were included in the inter-lab calculations. Eleven laboratories either did not report their copy number data or used other reporting units such as nanograms or cell numbers; therefore, only 26 laboratories were included in the overall analysis of copy numbers. The median copy number was 348.4, with a range from 15.6 to 547,000 copies (approximately a 4.5 log difference); the median intra-lab %CV was 19.2% with a range from 4.2% to 82.6%. While our international performance evaluation using serially diluted RNA samples has reinforced the fact that heterogeneity exists among clinical laboratories, it has also demonstrated that performance within a laboratory is overall very consistent. Accordingly, the availability of defined BCR/ABL RNAs may facilitate the validation of all phases of quantitative BCR/ABL analysis and may be extremely useful as a tool for monitoring assay performance. Ongoing analyses of these materials, along with the development of additional control materials, may solidify consensus around their application in routine laboratory testing and possible integration in worldwide efforts to standardize quantitative BCR/ABL testing.

Top Three Pharmacogenomics and Personalized Medicine Applications at the Nexus of Renal Pathophysiology and Cardiovascular Medicine.

Pharmacogenomics is a field with origins in the study of monogenic variations in drug metabolism in the 1950s. Perhaps because of these historical underpinnings, there has been an intensive investigation of 'hepatic pharmacogenes' such as CYP450s and liver drug metabolism using pharmacogenomics approaches over the past five decades. Surprisingly, kidney pathophysiology, attendant diseases and treatment outcomes have been vastly under-studied and under-theorized despite their central importance in maintenance of health, susceptibility to disease and rational personalized therapeutics. Indeed, chronic kidney disease (CKD) represents an increasing public health burden worldwide, both in developed and developing countries. Patients with CKD suffer from high cardiovascular morbidity and mortality, which is mainly attributable to cardiovascular events before reaching end-stage renal disease. In this paper, we focus our analyses on renal function before end-stage renal disease, as seen through the lens of pharmacogenomics and human genomic variation. We herein synthesize the recent evidence linking selected Very Important Pharmacogenes (VIP) to renal function, blood pressure and salt-sensitivity in humans, and ways in which these insights might inform rational personalized therapeutics. Notably, we highlight and present the rationale for three applications that we consider as important and actionable therapeutic and preventive focus areas in renal pharmacogenomics: 1) ACE inhibitors, as a confirmed application, 2) VDR agonists, as a promising application, and 3) moderate dietary salt intake, as a suggested novel application. Additionally, we emphasize the putative contributions of gene-environment interactions, discuss the implications of these findings to treat and prevent hypertension and CKD. Finally, we conclude with a strategic agenda and vision required to accelerate advances in this under-studied field of renal pharmacogenomics with vast significance for global public health.

La recepción tomista del análisis aristotélico de la crematística y su aplicación en la moderna doctrina social de la Iglesia

El concepte d’economia subjacent en el desenvolupament de la generalitat de les transaccions mercantils de la nostra era ha fet cas omís als seus orígens aristotèlics en un nombre de casos excessivament significatius, i ha prescindit d’unes arrels ordenades al servei recte de la vida bona de l’home. Per això, la Doctrina Social de l’Església ha manifestat la seva preocupació envers el desordre moral que regeix la conducta dels individus de la comunitat política quant a l’adquisició i administració dels béns materials que Déu els confià, i així mateix ha marcat una clara distinció entre les ciències econòmiques modernes, que ignoren tot component ètic, i la seva accepció ontològica, d’acord amb la qual l’economia es troba íntimament vinculada a la moralitat. Així, les ensenyances del Magisteri de l’Església Catòlica fan una crida al sentit d’“economia” derivat dels mots oikonomike i chrematistike limitada –l’art adquisitiu necessari i natural- que Aristòtil abordà en l’Antiguitat i que Sant Tomàs d’Aquino posteriorment rebé durant l’Edat Mitjana valent-se de diversos matisos; és a saber, invoquen el substrat moral que el Filòsof i el Doctor Angèlic compartiren des de la respectiva perspectiva pagana i catòlica: la dinàmica de l’economia contemporània s’allunya de l’“administració domèstica” de l’Estagirita per esdevenir una realitat desnaturalitzada, atesa la seva identificació amb aquella vessant de la crematística contranatural que exalça les passions mundanes. Sens perjudici de les especificitats històriques que inevitablement condicionaren el tractament de la dita qüestió a mans dels al•ludits autors, cal subratllar que la contribució més rellevant en aquest àmbit es veu reflectida en la presentació d’un art crematístic econòmic, necessari i natural, en contraposició a l’antieconòmic, que obviava el fi últim de la comunitat en tant que s’incorria en una alteració entre els mitjans posats a disposició de l’acompliment de la vida bona i tal finalitat. L’Aquinate reprengué el plantejament aristotèlic fent especial insistència en el paper de l’home amb relació a Déu, mentre que la Doctrina Social de l’Església –emprant dades de raó i fe- l’introduí en les seves pautes orientadores de la faceta econòmica de la vida social per, lluny d’aportar un model descoratjador del progrés humà, ordenar aquells aspectes de la comunitat que, sota els efectes de l’economia moderna o la crematística innatural, deixen en un segon pla l’amor al Pare. Si bé és ben cert que alguns dels passatges aristotèlics i tomistes contenen una oposició expressa a determinats gèneres adquisitius pel fet d’enquadrar-se en la crematística innecessària i innatural, el clímax dels seus raonaments no se centra tant en l’anàlisi de la coherència d’unes classificacions taxonòmiques com a resposta de les particularitats del moment, sinó en uns principis l’aplicació dels quals ha perdurat fins als nostres dies. En definitiva, l’herència d’aquells autors s’expressa en les premisses morals de les quals el Magisteri s’ha servit per establir la “definició universal” de les bases econòmiques, d’on se segueix la desaparició de tota nota dissonant entre l’economia desvirtuada de la modernitat i la seva essència assentada en l’oikonomike.
