    Klinefelter syndrome (KS) is one of the most common genetic causes of male infertility. This condition is associated with much comorbidity and with a lower life expectancy. The aim of this review is to explore more in depth cardiovascular and metabolic disorders associated to KS. KS patients have an increased risk of cerebrovascular disease (standardized mortality ratio, SMR, 2.2; 95% confidence interval, CI, 1.6-3.0), but it is not clear whether the cause of the death is of thrombotic or hemorrhagic nature. Cardiovascular congenital anomalies (SMR, 7.3; 95% CI, 2.4-17.1) and the development of thrombosis or leg ulcers (SMR, 7.9; 95% CI, 2.9-17.2) are also more frequent in these subjects. Moreover, cardiovascular abnormalities may be at least partially reversed by testosterone replacement therapy (TRT). KS patients have also an increased probability of endocrine and/or metabolic disease, especially obesity, metabolic syndrome and type 2 diabetes mellitus. The effects of TRT on these abnormalities are not entirely clear.

    Full Text Available Apoptosis is required for normal heart development in the embryo, but has also been shown to be an important factor in the occurrence of heart disease. Alternative splicing of apoptotic genes is currently emerging as a diagnostic and therapeutic target for heart disease. This review addresses the involvement of abnormalities in alternative splicing of apoptotic genes in cardiac disorders including cardiomyopathy, myocardial ischemia and heart failure. Many pro-apoptotic members of the Bcl-2 family have alternatively spliced isoforms that lack important active domains. These isoforms can play a negative regulatory role by binding to and inhibiting the pro-apoptotic forms. Alternative splicing is observed to be increased in various cardiovascular diseases with the level of alternate transcripts increasing elevated in diseased hearts compared to healthy subjects. In many cases these isoforms appear to be the underlying cause of the disease, while in others they may be induced in response to cardiovascular pathologies. Regardless of this, the detection of alternate splicing events in the heart can serve as useful diagnostic or prognostic tools, while those splicing events that seem to play a causative role in cardiovascular disease make attractive future drug targets.

  6. Genetic disorders with both hearing loss and cardiovascular abnormalities.

    There has been a growing appreciation for conditions that affect hearing and which are accompanied by significant cardiovascular disorders. In this chapter we consider several broad classes of conditions including deafness due to abnormal structural development of the inner ear, those with physiological abnormalities in the inner ear sensory apparatus, and conditions with progressive loss of function of sensory cells or middle ear functions. Because of shared developmental controls, inner ear malformations are often associated with congenital heart defects and can be part of complex syndromes that affect other organs and neurodevelopmental outcome. Physiological disorders of the hair cells can lead to hearing loss and can be associated with cardiac arrhythmias, especially long QT syndrome. In addition, cellular energy defects such as mitochondrial disorders can affect maintenance of hair cells and are often associated with cardiomyopathy. Lysosomal storage diseases and other disorders affecting connective tissue can lead to chronic middle ear disease, with conductive hearing loss and also cause cardiac valve disease and/or cardiomyopathy. The genetic basis for these conditions is heterogeneous and includes chromosomal/genomic disorders, de novo dominant mutations, and familial dominant, autosomal-recessive, and mitochondrial (matrilineal) inheritance. Taken together, there are more than 100 individual genes implicated in genetic hearing impairment that are also associated with congenital and/or progressive cardiac abnormalities. These genes encode transcription factors, chromatin remodeling factors, components of signal transduction pathways, ion channels, mitochondrial proteins and assembly factors, extracellular matrix proteins, and enzymes involved in lysosomal functions.

    Pharmacogenetics primarily uses genetic variation to identify subgroups of patients who may respond differently to a certain medication. Since its first description, the field of pharmacogenetics has expanded to study a broad range of cardiovascular drugs and has become a mainstream research discipline. Three principle classes of pharmacogenetic markers have emerged: 1) pharmacokinetic; 2) pharmacodynamic; and 3) underlying disease mechanism. In the realm of cardiovascular pharmacogenetics, significant advances have identified markers in each class for a variety of therapeutics, some with a potential for improving patient outcomes. While ongoing clinical trials will determine if routine use of pharmacogenetic testing may be beneficial, the data today support pharmacogenetic testing for certain variants on an individualized, case-by-case basis. Our primary goal is to review the association data for the major pharmacogenetic variants associated with commonly used cardiovascular medications: antiplatelet agents, warfarin, statins, beta-blockers, diuretics, and antiarrhythmic drugs. In addition, we highlight which variants and in which contexts pharmacogenetic testing can be implemented by practicing clinicians. The pace of genetic discovery has outstripped the generation of the evidence justifying its clinical adoption. Until the evidentiary gaps are filled, however, clinicians may choose to target therapeutics to individual patients whose genetic background indicates that they stand to benefit the most from pharmacogenetic testing.

    Full Text Available One of the consistent findings among various studies on HIV has been simultaneous multiorgan dysfunction. Cardiovascular disorders are now most common cause of mortality worldwide. With more effective and widespread treatment of HIV in resource-rich settings, morbidity and mortality from non-AIDS-related events have surpassed those from AIDS-related events with cardiovascular diseases emerging as an important cause of death in HIV-infected patients relative to the decreasing incidence of opportunistic disease. Various studies have reported a 1.5-fold increase in the rate of cardiovascular events in HIV-infected individuals compared to control populations. MATERIAL AND METHODS The aim of the study was to the find the prevalence and types of different cardiovascular abnormalities in HIV positive patients and assess their association with CD4 counts. Consecutive 82 patients, HIV positive patients fulfilling the inclusion criteria and giving informed consent were included in the study. All patients were subjected to history taking and a detailed physical examination. Blood counts, renal function tests, lipid profile and CD4 counts were estimated and patients were subjected to 12-lead ECG, chest X-ray and 2D/Colour Doppler Echocardiogram. RESULTS Of the 82 patients studied 47.46% had evidence of cardiovascular involvement, out of which 12% had clinical features of heart failure while electrocardiographic changes were seen in 35% of patients in the form of sinus tachycardia (27%, QTc prolongation (10% and left sided chamber enlargements (6%. Echocardiographic abnormalities were noted in 39 patients (47.56% including fractional shortening associated with systolic dysfunction (26.8%. The mean CD4 count in patients with echocardiographic abnormalities was found to be 58.87±29.80, whereas in patients without echocardiographic abnormalities it was 136.53±38.80 (p<0.0001. CONCLUSION High frequencies of cardiac abnormalities, both symptomatic and

    Full Text Available Therapies currently implemented for obesity are focused on nutritional aspects and on physical activity. In order to make physical activity a positive therapy instead of triggering disabilities it is relevant to accurately assess cardiovascular fitness. Objective: To assess the cardiovascular fitness by measuring the peak oxygen consumption and to asses their relationship with classical cardiometabolic parameters. Methods: A modified Balke protocol was applied to one hundred and twenty-six Caucasians (60% males, ranging between 9 and 16 years old, who underwent an assessment of obesity. The non-obese group consisted of healthy age and sex matched subjects who were invited to participate from the general population. Results: Significant differences in consumption of oxygen peak between non-obese and obese individuals were observed. In contrast, no significant differences existed between the categories of obesity. Furthermore in obese subjects consumption of oxygen peak was inversely correlated with parameters of cardiometabolic risk, particularly insulin and HOMA index. In addition, two predictive equations of consumption of oxygen peak, with an R² of 0.74 and 0.84, respectively, have been developed. Conclusion: The consumption of oxygen peak is a relevant clinical parameter that should be included in the routine clinical assessment of obese subjects. Therefore, it is crucial to make exercise tests more affordable which can be achieved by employing predictive equations.

    Full Text Available Flavio Danni Fuchs, Sandra Costa Fuchs, Leila Beltrami Moreira, Miguel GusDivision of Cardiology and Postgraduate Studies Program in Cardiology, Hospital de Clinicas de Porto Alegre, Universidade Federal do Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, BrazilAbstract: High blood pressure and lipoprotein abnormalities were identified by many cohort studies as the major risk factors for cardiovascular disease. Laboratory experiments apparently confirmed their role in the causation of atherosclerosis, but a proof of concept requires the corroboration by clinical trials in human beings. The size of benefit in clinical trials regarding the control of high blood pressure was within the estimations of risk provided by cohort studies. For a reduction of 10 mmHg in systolic blood pressure or 5 mmHg in diastolic blood pressure, the relative risk reduction of coronary heart disease was 22% (95% confidence interval 27%–17% in a meta-analysis of clinical trials, close to the estimation of reduction of 25% (95% confidence interval 23%–27% provided by a meta-analysis of cohort studies. The corresponding values for stroke were 41% (95% confidence interval 33%–48% in clinical trials compared to a cohort risk prediction of 36% (95% confidence interval 34%–38%. This efficacy was shared by all blood pressure-lowering drugs. The same figure has not paradoxically happened with drugs that act over abnormalities of cholesterol and lipoproteins. Only statins, which have other beneficial actions as well, have consistently lowered the incidence of cardiovascular diseases, an efficacy that was not reproduced by older and newer quite potent lipid drugs. The adverse effects of these drugs may nullify their beneficial effects over lipoproteins and abnormalities of lipoproteins may only be surrogate markers of the underlying real risks.Keywords: proof of concept, hypertension, lipoproteins, clinical trials

    Full Text Available OBJECTIVE: To evaluate the cardiovascular findings and clinical follow-up of patients with Williams-Beuren syndrome. METHODS: We studied 20 patients (11 males, mean age at diagnosis: 5.9 years old, assessed for cardiovascular abnormalities with electrocardiography and Doppler echocardiography. Fluorescence in situ hybridization (FISH was used to confirm the diagnosis of the syndrome. RESULTS: Elastin gene locus microdeletion was detected in 17 patients (85% (positive FISH, and in 3 patients deletion was not detected (negative FISH. Sixteen patients with a positive FISH (94% had congenital cardiovascular disease (mean age at diagnosis: 2,3 years old. We observed isolated (2/16 supravalvular aortic stenosis and supravalvular aortic stenosis associated (11/16 with pulmonary artery stenosis (4/11; mitral valve prolapse (3/11; bicuspid aortic valve (3/11; aortic coarctation (2/11, thickened pulmonary valve (2/11; pulmonary valvular stenosis (1/11; supravalvular pulmonary stenosis (1/11; valvular aortic stenosis (1/11; fixed subaortic stenosis (1/11; pulmonary artery stenosis (2/16 associated with pulmonary valvar stenosis (1/2 and with mitral valve prolapse (1/2; and isolated mitral valve prolapse (1/16. Four patients with severe supravalvular aortic stenosis underwent surgery (mean age: 5.7 years old, and 2 patients had normal pressure gradients (mean follow-up: 8.4 years. CONCLUSION: A detailed cardiac evaluation must be performed in all patients with Williams-Beuren syndrome due to the high frequency of cardiovascular abnormalities.

    With ever-increasing sophistication of veterinary cardiology, minimally invasive per-catheter occlusion and dilation procedures for the treatment of various congenital cardiovascular abnormalities in dogs have become not only available, but mainstream. Much new information about minimally invasive per-catheter patent ductus arteriosus occlusion has been published and presented during the past few years. Consequently, patent ductus arteriosus occlusion is the primary focus of this article. Occlusion of other less common congenital cardiac defects is also briefly reviewed. Balloon dilation of pulmonic stenosis, as well as other congenital obstructive cardiovascular abnormalities is discussed in the latter part of the article.

    Cardiovascular magnetic resonance imaging (MRI) has evolved from an effective research tool into a clinically proven, safe and comprehensive imaging modality. It provides anatomic and functional information in acquired and congenital heart disease and is the most precise technique for quantification of ventricular volumes, function and mass. Owing to its excellent interstudy reproducibility, cardiovascular MRI is the optimal method for assessment of changes in ventricular parameters after therapeutic intervention. Delayed contrast enhancement is an accurate and robust method used in the diagnosis of ischemic and nonischemic cardiomyopathies and less common diseases, such as cardiac sarcoidosis and myocarditis. First-pass magnetic contrast myocardial perfusion is becoming an alternative to radionuclide techniques for the detection of coronary atherosclerotic disease. In this review we outline the techniques used in cardiovascular MRI and discuss the most common clinical applications. (author)

    Few cases of mexiletine overdose have been reported in the literature. The available case reports have invariably noted significant hemodynamic or electrocardiographic abnormalities. A 41-year-old woman, on mexiletine for arrhythmia control, ingested up to 90 of her 200 mg mexiletine tablets in a suicide attempt. She presented to the emergency department awake with a normal blood pressure and pulse. Shortly afterwards, the patient had a generalized motor seizure, which responded after 40 minutes to intravenous diazepam 100 mg, phenobarbital 1 g and pyridoxine 5 g. Recurrent status epilepticus at one hour required an additional 40 mg of diazepam and a loading dose of pentobarbital. During the entire episode, her electrocardiogram remained normal. The patient's mexiletine level was 20 micrograms/mL (therapeutic 1-2 micrograms/mL) and the patient's urine screen was negative for cocaine. Mexiletine is a group Ib antidysrhythmic agent with electrophysiologic effects similar to lidocaine. Mexiletine has a little first pass hepatic metabolism and a large volume of distribution along with a high lipid solubility, and prolonged central nervous system toxicity may be expected. As with lidocaine, the toxic deaths from mexiletine have resulted from hypotension and bradycardia. The patient reported had a significant mexiletine overdose which resulted in convulsive status epilepticus, but was devoid of hemodynamic or electrocardiographic abnormalities.

    Objectives Most medical instruments are designed for diagnosis purpose but very few for clinical treatment. Our research aim is to design and develop a cardiovascular automatic feedback control instrument (CAFCI) for rescuing the critical patients with abnormal blood pressure.Methods The CAFCI was designed on the basis of abundant clinical experiences and on successful mathematic modeling of our experimental data. The blood pressure, pulmonary capillary wedge pressure,and rates of heart beat were measured and inputted into a computer and drugs were chosen by a doctor through a user-friendly interface with the computer.The responses to medication were rapidly acquired and feed back to the computer by automatic detection system in a close-loop system. The data were refreshed every 7.5 sec in order to regulate the speed and dosage of the medications that were given. Results The experimental results with ten dogs showed that the CAFCI system took samples promptly and accurately so that the targeted blood pressure could be reached reliably based on our input parameters and our designing requirements. Conclusions Since the dependability and accuracy of the CAFCI system are much superior to that of the traditional method, its clinical application to rescue the critical patient warrants evaluation in the future.

    Las terapias que se implantan actualmente para la obesidad se centran en los aspectos nutricionales y sobre la actividad física. Con el fin de hacer que la actividad física sea una terapia positiva en vez de un desencadenador de discapacidades, es relevante evaluar de forma precisa el entrenamiento cardiovascular. Objetivo: evaluar el entrenamiento cardiovascular midiendo el consumo máximo de oxígeno y evaluar su relación con los parámetros cardiometabólicos clásicos. Métodos: se aplicó el protocolo modificado de Balke a 126 individuos caucásicos (60 % de varones), con edades entre 9 y 16 años, que se sometieron a una evaluación de obesidad. El grupo de no obesos consistía de individuos sanos, de la población general, emparejados por edad y sexo y a los que se les invitó a participar. Resultados: se observaron diferencias significativas en el consumo máximo de oxígeno entre los indiviudos obesos y no obesos. Por contra, no existían diferencias significativas entre las categorías de obesidad. Además, en los sujetos obesos, el consumo máximo de oxígeno se correlacionó de forma inversa con los parámetros de riesgo cardiometabólico, particularmente con la insulina y el índice HOMA. Además, se han desarrollado dos ecuaciones predictivas del consumo máximo de oxígeno con una R2 de 0,74 y de 0,84, respectivamente. Conclusión: el consumo máximo de oxígeno es un parámetro clínico relevante que debería incluirse en la evaluación clínica rutinaria de los sujetos obesos. Por lo tanto, es crucial hacer que las pruebas de esfuerzo sean más asequibles, que puedan alcanzarse empleando las ecuaciones predictivas.

    Objective The prognostic importance of changes in ischaemic ECG abnormalities over time (especially ST-T abnormalities) among Asians has not been fully investigated. We examined the associations between changes in ischaemic abnormalities upon serial ECG (improvement, persistence, deterioration) and cardiovascular disease (CVD) risk. Methods A prospective study cohort was conducted with 9374 men and women aged 40–69 years in four communities. Participants had multiple ECGs at study entry and during the next 10 years, and were followed up for a median period of 23.0 years. Total CVD (stroke and coronary heart disease) was ascertained under systematic surveillance. ECG abnormalities were defined by the Minnesota Code, ST depression (Code4), abnormal T wave (Code5) and categorised into nine groups (no–no, no–minor, no–major, minor–no, minor–minor, minor–major, major–no, major–minor, major–major) by comparison with the point of entrance and maximum change. Results We documented 1196 CVD events. Compared with no–no abnormality, no–minor, minor–major and major–major in Code4, HRs (95% CI) adjusted for cardiovascular risk factors were 1.19 (1.00–1.42), 1.57 (1.15–2.12) and 1.87 (1.42–2.47). Similar results were observed in Code5. Conclusions Changes in ischaemic ECG abnormalities from none to minor, and minor to major, as well as persistent major abnormalities, were associated with an increased risk of CVD. PMID:28176973

    Increases in pancreatic enzyme levels after cardiovascular surgery were studied, and their clinical characteristics evaluated. The subjects were 128 patients who had undergone cardiovascular surgery (65 patients after valve replacement, 32 after coronary bypass surgery and 31 after aortic artificial graft replacement). The pancreatic enzyme (serum amylase and lypase) levels were monitored serially before and after operation, and amylase fractions were measured at their peaks. The relationships of the peak lypase level with underlying cardiac diseases, background factors, factors related to surgery, factors related to the extracorporeal circulation, presence or absence of symptoms, and treatments were examined. The amylase level exhibited biphasic changes consisting of a peak in which salivary glands amylase (S type) was dominant and a peak in which pancreatic amylase (P type) was dominant. The second peak coincided with the peak lypase and occurred mostly 3 to 10 days after operation. The peak lypase level exceeded the normal range in 78% of all the patients. It exceeded 564 U/l, 4 times the normal value in 28% of the patients, many of whom were symptomatic. So, we recommended that these cases should be treated as "postoperative pancreatitis". A high peak lypase level showed a significant correlation with the history of gallbladder and pancreatic diseases and diabetes mellitus among the background factors and emergency operation and the use of IABP among the surgery-related factors.(ABSTRACT TRUNCATED AT 250 WORDS)

    With increasing use of pediatric cardiovascular MRI, it is important for all imagers to become familiar with the spectrum of non-cardiovascular imaging findings that can be encountered. This study aims to ascertain the prevalence and nature of these findings in pediatric cardiovascular MRIs performed at our institution. We retrospectively evaluated reports of all cardiovascular MRI studies performed at our institute from January 2008 to October 2012 in patients younger than18 years. Most studies (98%) were jointly interpreted by a pediatric cardiologist and a radiologist. We reviewed the electronic medical records of all cases with non-cardiovascular findings, defined as any imaging finding outside the cardiovascular system. Non-cardiovascular findings were classified into significant and non-significant, based on whether they were known at the time of imaging or they required additional workup or a change in management. In 849 consecutive studies (mean age 9.7 ± 6.3 years), 145 non-cardiovascular findings were found in 140 studies (16.5% of total studies). Overall, 51.0% (74/145) of non-cardiovascular findings were in the abdomen, 30.3% (44/145) were in the chest, and 18.6% (27/145) were in the spine. A total of 19 significant non-cardiovascular findings were observed in 19 studies in individual patients (2.2% of total studies, 47% male, mean age 5.9 ± 6.7 years). Significant non-cardiovascular findings included hepatic adenoma, arterially enhancing focal liver lesions, asplenia, solitary kidney, pelvicaliectasis, renal cystic diseases, gastric distention, adrenal hemorrhage, lung hypoplasia, air space disease, bronchial narrowing, pneumomediastinum and retained surgical sponge. Non-cardiovascular findings were seen in 16.5% of cardiovascular MRI studies in children, of which 2.2% were clinically significant findings. Prevalence and nature of these non-cardiovascular findings are different from those reported in adults. Attention to these findings is important

    Accurate assessment of cardiovascular (CV) risk is a prerequisite for devising effective therapeutic strategies in patients with type 2 diabetes (T2DM) as it allows to refine prognosis and treatment targets as well as the cost-benefit ratio for specific pharmacological interventions. The presence of subclinical vascular organ damage plays a well known role in determining overall risk and a wider use of low cost, easy to perform diagnostic tools to stratify CV risk is very much needed. Besides their well known prognostic value for progression to end stage renal disease (ESRD), subclinical renal abnormalities such as microalbuminuria and/or a slight reduction in estimation of glomerular filtration rate (eGFR), have been shown to be powerful, independent predictors of CV diseases in patients with T2DM. Through the combined evaluation of these two biomarkers of chronic kidney disease (CKD), clinicians can usefully and reliably get a perspective on global and CV outcome of their diabetic patients.

    Full Text Available Due to the signifi¬cant increase of complications developing in young people suffering from low cardiac abnormalities, detection of this disease is important. The aim of the study was to analyze the prevalence and structure of cardiovascular diseases in persone aged 18-21 years who have referred to the medical center of Dnepropetrovsk Medical Academy in the period from 2012 to 2013 in order to determine the mode of physicol exercises. We examined 268 students of 1-2 courses of medical academy, who, along with the clinical examination underwent standard echocardiography 2 times a year. It is established that in the structure of cardiovascular diseases in the studied group small anomalies of the heart occupy the first place; valve pathology the second place. In the structure of small abnormality of the heart, mitral valve prolapse is detected the most frequently. Since this anomaly affects the level of tolerance to physical stress and can lead to heart disorder, routine screening of patients with this disease is mandatory and must be carried out to address the choice of the level of physical activity.

    Current clinical cardiovascular practice requires a clinician to have a strong foundation in multiple aspects of pharmacology. Modern cardiovascular regimens are complex, and optimal management, application of evolving guidelines, and adoption of new therapies build off a more basic understanding of pharmacokinetics and pharmacodynamics. In addition, it is likely time to add a third pillar into this discussion, the expanding field of pharmacogenomics referring to the genetic influences on drug response. This field has increasing applications in medicine and clearly holds significant promise for cardiovascular disease management. Awareness of pharmacogenomic advances and the fundamentals of pharmacokinetics and pharmacodynamics can help the clinician more easily deliver great care. Here we attempt to briefly summarize and simplify key concepts of pharmacokinetics, pharmacodynamics, and pharmacogenomics relevant to the cardiovascular disease practitioner.

    Clinically significant cardiovascular malformations (CVMs) occur in 5-8 per 1000 live births. Recurrent copy number variations (CNVs) are among the known causes of syndromic CVMs, accounting for an important fraction of cases. We hypothesized that many additional rare CNVs also cause CVMs and can be detected in patients with CVMs plus extracardiac anomalies (ECAs). Through a genome-wide survey of 203 subjects with CVMs and ECAs, we identified 55 CNVs >50 kb in length that were not present in children without known cardiovascular defects (n=872). Sixteen unique CNVs overlapping these variants were found in an independent CVM plus ECA cohort (n=511), which were not observed in 2011 controls. The study identified 12/16 (75%) novel loci including non-recurrent de novo 16q24.3 loss (4/714) and de novo 2q31.3q32.1 loss encompassing PPP1R1C and PDE1A (2/714). The study also narrowed critical intervals in three well-recognized genomic disorders of CVM, such as the cat-eye syndrome region on 22q11.1, 8p23.1 loss encompassing GATA4 and SOX7 and 17p13.3-p13.2 loss. An analysis of protein-interaction databases shows that the rare inherited and de novo CNVs detected in the combined cohort are enriched for genes encoding proteins that are direct or indirect partners of proteins known to be required for normal cardiac development. Our findings implicate rare variants such as 16q24.3 loss and 2q31.3-q32.1 loss, and delineate regions within previously reported structural variants known to cause CVMs.

    Objective: To study the value of detecting fetal congenital heart disease (CHD) using the five transverse planes technique of fetal echocardiography. Methods: Nine hundred and eighty-two high-risk pregnancies for fetal CHD were included in this study, the fetal heart was scanned with the five transverse planes technique of fetal echocardiography described by yagel, autopsy was conducted when pregnancy was terminated. Blood from fetal heart was collected for fetal chromosome analysis. A close follow-up was given for normal fetal heart pregnancies and neconatal echocardiography was performed to check the accuracy of prenatal diagnosis. Results: (1) Forty-six cases(4.68%) were found to have fetal heart abnormalities in this study, 69.56% of them were diagnosed by single four-chamber view, another 30.43% fetal CHD were found by combining other views; (2) Fotry-one parents of prenatal fetuses with CHD chose to terminate pregnancy, thirty-two of them gave consent to conduct autopsy, 93.75% of which yielded unanimous conclusion between prenatal fetal echocardiography and autopsy; (3) Thirty-two of 46 cases underwent fetal chromosome analysis, 8 cases (25%) were found to have abnormal chromosome; (4) Five cases were found to have right ventricle and atrium a little bigger than those on the left side, with the unequal condition being the same after birth, but there were no clinical manifestations and they are healthy for the time being; (5) Nine hundred and thirty-six cases were not found with abnormality in this study, but one case was diagnosed with ventricular septal defect after birth, one case was diagnosed with patent ductus arteriosus, one case had atrial septal defect after birth. Conclusions: (1) The detected CHD rate was 4.68% by screening fetal heart with five transverse planes according to Yagel's description of high risk population basis for CHD. The coinciding rate of prenatal diagnosis and autopsy was 93.75%; (2) The sensitivity of detecting fetal heart

    Congenital middle ear malformations are rare. Most part of them are usually associated with other malformations, such as aural atresia, microtia, and dysmorphic craniofacial features. A clinical case of a 24-year-old male with a right-sided conductive hearing loss since his childhood, without craniofacial malformation, is presented. He was proposed for exploratory tympanotomy under the suspicious diagnosis of otosclerosis. The surgery revealed an abnormal location of stapes' superstructure, which was attached to the promontory and had an isolated and mobile osseous footplate in the oval window. A stapes prosthesis was inserted and resulted in closure of the air-bone gap by 25 dB. A review of the literature was also performed using MEDLINE. Two theories diverge on the embryologic origin of the stapes. Our findings seem to be in favour of the theory that defines two different embryologic origins to the stapes. PMID:27648330

    Low-density lipoprotein (LDL) cholesterol concentration has been the prime index of cardiovascular disease risk and the main target for therapy. However, several lipoprotein ratios or "atherogenic indices" have been defined in an attempt to optimize the predictive capacity of the lipid profile. In this review, we summarize their pathophysiological aspects, and highlight the rationale for using these lipoprotein ratios as cardiovascular risk factors in clinical practice, specifying their cut-off risk levels and a target for lipid-lowering therapy. Total/high-density lipoprotein (HDL) cholesterol and LDL/HDL cholesterol ratios are risk indicators with greater predictive value than isolated parameters used independently, particularly LDL. Future recommendations regarding the diagnosis and treatment of dyslipidemia, including instruments for calculating cardiovascular risk or action guidelines, should include the lipoprotein ratios with greater predictive power which, in view of the evidence-based results, are none other than those which include HDL cholesterol.

    Hemifacial spasm (HFS) is defined as an involuntary, irregular clonic, or tonic movement of muscles innervated by the ipsilateral seventh cranial nerve. It is reported that the coexistence of non-motor- and motor-related symptoms can be seen in patients with HFS. Postural disturbances were investigated in some movement disorders; however, postural abnormalities due to HFS had not been reported before. In this study, we aimed to investigate the postural abnormalities in patients with HFS. In this cross-sectional, controlled study, Tinetti Balance and Gait Test (TBGT) scores and static posturography were performed on fifteen patients with HFS and fifteen healthy age- and sex-matched controls. The total TBGT score and TBGT-balance score were found to be significantly lower in the patient group than in the control group (p values were, respectively, 0.046 and 0.011). The ratio of the patients with high risk of falling was 40 %, and the difference was found to be significantly higher in the patient group (p value = 0.008). In Fourier analyses, a significant difference was found in the medium to high frequencies (F5-6) when the posturographic evaluation was performed on a solid ground with closed eyes, head rotated to right, and head rotated to the left positions (p values were, respectively, 0.045 and 0.007). The stability index of the HFS group was significantly higher than the control group when tested on the neutral, head right, and head left positions (p values were, respectively, 0.004, 0.049, and 0.003). In conclusion, our study showed that the patients with HFS have more balance and falling problems than the controls, which can be both clinically and posturographically determined.

    decline associated with cardiac diseases is characterized mainly by impairments of memory (learning and fixation, attention and information processing. In this article, we review neuroimaging abnormalities that may be found in samples of subjects presenting with cardiovascular risk factors and cognitive decline, including regional brain volumetric changes, white matter hyperintensities, silent brain infarcts, lacunars infarcts, and functional deficits in global blood flow (associated to reduced cardiac output or regional cerebral blood flow. We discuss the implications of these findings to the knowledge about the pathophysiology of cognitive deficits associated with cardiovascular risk factors, as well as their potential clinical applications. Finally, we discuss the potential use of novel imaging technologies in future studies evaluating abnormalities in brain structure and function related to cardiovascular risk factors, in large samples of elderly patients.

It provides pure heart rate reduction, reducing the diastolic depolarization slope, without altering hemodynamic parameters. This review summarizes the current knowledge on the efficacy of ivabradine in patients with cardiovascular diseases, with a particular focus on its role in the clinical management of patients with CAD and HF. There is consistent evidence that ivabradine is effective in reducing angina pectoris symptoms and myocardial ischemia. At approved doses ivabradine is safe, improves exercise tolerance, and reduces heart rate. Available data from clinical trials support its use in the management of patients with stable CAD and chronic HF. Recent studies have cast doubt on the safety of non-approved high doses of ivabradine for the treatment of patients with CAD and without clinical HF, but have shown no concerns on the doses approved for clinical use.

    Full Text Available Targeting the renin-angiotensin-aldosterone system (RAAS, specifically the effector peptide angiotensin II (Ang II, represents a major opportunity for slowing the progression of cardiovascular disease (CVD and, in turn, reducing the risk of morbidity and mortality. Inhibition of angiotensin-converting enzyme (ACE and selective blockade of Ang II AT1 receptors are two approaches through which the pathophysiological effects of Ang II can be targeted. Numerous clinical studies have established the benefits of ACE inhibitors P, (ACE-Is in lessening the morbidity and mortality burden of CVD. There are, however, tolerability concerns associated with ACE-Is, such as angioedema and dry cough. By blocking Ang II at the AT1 receptor level, Ang II receptor blockers (ARBs provide a more specific and complete blockade of the deleterious effects of Ang II and tend to have more favourable tolerability. A number of clinical trials have shown that ARBs are not only associated with positive outcomes across the CVD continuum but may also have a role in the prevention or delay of diabetes (a major cardiovascular risk factor. Ongoing trials are aiming to define the place of such agents in lessening morbidity and mortality from CVD.

    South Asians have a high prevalence of coronary heart disease(CHD) and suffer from early-onset CHD compared to other ethnic groups. Conventional risk factors may not fully explain this increased CHD risk in this population. Indeed, South Asians have a unique lipid profile which may predispose them to premature CHD. Dyslipidemia in this patient population seems to be an important contributor to the high incidence of coronary atherosclerosis. The dyslipidemia in South Asians is characterized by elevated levels of triglycerides, low levels of high-density lipoprotein(HDL) cholesterol, elevated lipoprotein(a) levels, and a higher atherogenic particle burden despite comparable low-density lipoprotein cholesterol levels compared with other ethnic subgroups. HDL particles also appear to be smaller, dysfunctional, and proatherogenic in South Asians. Despite the rapid expansion of the current literature with better understanding of the specific lipid abnormalities in this patient population, studies with adequate sample sizes are needed to assess the significance and contribution of a given lipid parameter on overall cardiovascular risk in this population. Specific management goals and treatment thresholds do not exist for South Asians because of paucity of data. Current treatment recommendations are mostly extrapolated from Western guidelines. Lastly, large, prospective studies with outcomes data are needed to assess cardiovascular benefit associated with various lipid-lowering therapies(including combination therapy) in this patient population.

    Full Text Available OBJECTIVE: The purpose of this study is to evaluate the impact of transeophageal echocardiography on management of patients at low-risk for cardiogenic embolism to prevent new potential cardiovascular sources of emboli. METHODS: We studied 69 patients with ischemic stroke at low-risk for cardiogenic embolism. Transeophageal echocardiography was performed to access: left atrium enlargement; communication or aneurysm of the interatrial septum; patent foramen ovale; spontaneous echo contrast or intracavitary thrombi; the presence of intraaortic atherosclerotic plaques or thrombi; significant valvar morphologic alteration or dysfunction; left ventricle enlargement, hypertrophy, or contractile abnormality. Transesophageal echocardiography altered clinical management, and we adopted anticoagulant therapy or another procedure apart from the use of acetylsalicylic acid. RESULTS: Transeophageal echocardiography detected at least one abnormality in 40 cases (58%. Clinical conduct was adjusted after the performance of transesophageal echocardiography in 11 patients (15.9%; anticoagulation was added in 10 cases and surgical correction in one patient. CONCLUSION: Transeophageal echocardiography was a very useful tool in the secondary prevention for stroke in patients at low risk for cardiogenic embolism.

    Full Text Available Depersonalization disorder (DPD is characterized by subjective unreality, disembodiment, emotional numbing and reduced psychogenic sympathoexcitation. 3 related experiments used physical and emotional challenges in 14 DPD participants and 16 controls to elucidate whether the cardiovascular sympathetic (SNS and parasympathetic (PNS nervous systems are implicated in DPD and if blunted DPD sympathoexcitation is peripherally or centrally mediated. Participants completed the Beck Anxiety Inventory (BAI, Dissociative Experience Scale (DES and Cambridge Depersonalization Scale (CDS. Study I recorded heart rate (HR and blood pressure (BP during 5mins supine baseline, 3mins handgrip (HG, 3mins cold pressor (CP and 5mins 60°head-up tilt (HUT. Study II recorded HR, BP and heart rate variability (HRV during 5mins HUT and unpleasant images. Study III examined HR and BP orienting responses (ORs to HUT and unpleasant, neutral and pleasant images. DPD BAI (p=0.0004, DES (p=.0002 and CDS (p=< 0.0001 scores were higher than controls. The DPD group produced diminished diastolic BP (DBP (p=0.045 increases to HG. Other indices were comparable between groups. DPD participants produced diminished systolic BP (SBP (p=0.003 and DBP (p=0.002 increases, but greater (p=0.004 HR increases to CP. In study II, DPD high frequency HRV (HF-HRV – indicating parasympathetic vagal activity - was reduced (p=0.029. In study III, DPD DBP was higher throughout the 5s duration of HUT/pseudorandom unpleasant image presentation (1s [p=0.002], 2s [p=0.033], 3s [p=0.001], 4s [p=0.009], 5s [p=0.029]. Study I’s BP pressor data supports previous findings of suppressed sympathoexcitatioin DPD. The greater HR increases to CP, decreased HF-HRV in study II, and increased DBP during unpleasant ORs in study III implicates the SNS and PNS in DPD pathophysiology. These studies suggest the cardiovascular autonomic dysregulation in DPD is likely to be centrally-mediated

    Full Text Available Background: The association between psoriasis, diabetes, and cardiovascular disease remains largely unelucidated in the Indian population. Aims: To study the prevalence of diabetes, insulin resistance, lipid abnormalities, and cardiovascular risk factors in patients with chronic plaque psoriasis. Materials and Methods: Seventy-seven patients of chronic plaque psoriasis and ninety two age- and sex-matched controls were enrolled in the study over a period of one year. Clinical and biometric data were noted and fasting venous blood samples were collected. Nondiabetic patients were subjected to an oral glucose tolerance test with 75 g glucose and postprandial venous blood samples collected at 120 mins. The fasting glucose, insulin, lipid levels, postprandial glucose and postprandial insulin levels were measured in samples from nondiabetic patients whereas fasting lipid levels only were measured in diabetic patients. Results: The prevalence of impaired fasting glucose, impaired glucose tolerance, and diabetes mellitus in psoriatics was 5.2%, 9.1%, and 32.5%, respectively, as compared to 6.5%, 3.3%, and 15.2%, respectively, in the controls. The difference was statistically significant. The odds ratio of having an abnormal glucose metabolism in psoriasis was 2.63. Smoking had a positive association with insulin resistance in psoriatic cases. The serum cholesterol levels were elevated in 29 (37.7% cases with a mean of 186.27 ± 43.18 and 34 (37% controls with a mean of 194.38 ± 57.20. The serum HDL-cholesterol levels were reduced in 50 (64.9% cases with a mean of 53.29 ± 15.90 as compared to 71 (74.7% in controls with a mean of 48.76 ± 12.85. The serum LDL-cholesterol levels were elevated in 38 (49.4% cases with a mean of 102.56 ± 44.02 and 36 controls with a mean of 115.62 ± 54.37.

    Today, the use of cardiovascular magnetic resonance (CMR) is widespread in clinical practice. The increased need to evaluate of subtle myocardial changes, coronary artery anatomy, and hemodynamic assessment has prompted the development of novel CMR techniques including T1 and T2 mapping, non-contrast angiography and four dimensional (4D) flow. T1 mapping is suitable for diagnosing pathologies affecting extracellular volume such as myocarditis, diffuse myocardial fibrosis and amyloidosis, and is a promising diagnostic tool for patients with iron overload and Fabry disease. T2 mapping is useful in depicting acute myocardial edema and estimating the amount of salvageable myocardium following an ischemic event. Novel angiography techniques, such as the self-navigated whole-heart or the quiescent-interval single-shot sequence, enable the visualization of the great vessels and coronary artery anatomy without the use of contrast material. The 4D flow technique overcomes the limitations of standard phase-contrast imaging and allows for the assessment of cardiovascular hemodynamics in the great arteries and flow patterns in the cardiac chambers. In conclusion, the future of CMR is heading toward a more reliable quantitative assessment of the myocardium, an improved non-contrast visualization of the coronary artery anatomy, and a more accurate evaluation of the cardiac hemodynamics.

In this review, we summarize their pathophysiological aspects, and highlight the rationale for using these lipoprotein ratios as cardiovascular risk factors in clinical practice, specifying their cut-off risk levels and a target for lipid-lowering therapy. Total/high-density lipoprotein (HDL cholesterol and LDL/HDL cholesterol ratios are risk indicators with greater predictive value than isolated parameters used independently, particularly LDL. Future recommendations regarding the diagnosis and treatment of dyslipidemia, including instruments for calculating cardiovascular risk or action guidelines, should include the lipoprotein ratios with greater predictive power which, in view of the evidence-based results, are none other than those which include HDL cholesterol.Keywords: apolipoproteins

  8. Assessing quality-of-life outcomes in cardiovascular clinical research.

    The field of quality-of-life (QOL) measurement grew out of attempts in the 1960s and 1970s to connect the ever-increasing levels of public expenditure on technology-based health care for chronic diseases with evidence of the benefits and harms to patients. Most of the concepts, methods, and standards for measuring QOL were derived from psychometrics, but the degree to which current tools adhere to these methods varies greatly. Despite the importance of QOL, patient-reported outcomes are not measured in most cardiovascular clinical trials. Lack of familiarity with QOL measures and their interpretation, and unrealistic expectations about the information these measures can provide, are obstacles to their use. Large clinical trials of revascularization therapy for coronary artery disease and medical treatments for heart failure show small-to-moderate QOL effects, primarily detected with disease-specific instruments. Larger treatment effects, seen in trials of device therapy for heart failure and ablation therapy for atrial fibrillation, have been detected with both generic and disease-specific instruments. A large gap remains between the parameters currently being measured in clinical research and the data needed to incorporate the 'patient's voice' into therapeutic decision-making.

    Recent studies have shown that computerized clinical case management and decision support systems can be used to assist surgeons in the diagnosis of disease, optimize surgical operation, aid in drug therapy and decrease the cost of medical treatment. Therefore, medical informatics has become an extensive field of research and many of these approaches have demonstrated potential value for improving medical quality. The aim of this study was to develop a web-based cardiovascular clinical information system (CIS) based on innovative techniques, such as electronic medical records, electronic registries and automatic feature surveillance schemes, to provide effective tools and support for clinical care, decision-making, biomedical research and training activities. The CIS developed for this study contained monitoring, surveillance and model construction functions. The monitoring layer function provided a visual user interface. At the surveillance and model construction layers, we explored the application of model construction and intelligent prognosis to aid in making preoperative and postoperative predictions. With the use of the CIS, surgeons can provide reasonable conclusions and explanations in uncertain environments.

    Myeloid neoplasms with eosinophilia and abnormalities of PDGFRB gene are a new kind of myeloid disorders in the revised 2008 WHO classification. Out of detected 2000 cases of myeloid cell abnormalities in our hospital, 12 cases of myeloid neoplasms with eosinophilia and abnormalities of PDGFRB were found. This study was purposed to summarize and analyze the clinical and laboratorial characteristics of the 12 cases with PDGFRB gene abnormalities. The results indicated that among 12 cases of myeloid neoplasms with PDGFRB abnormalities, 5 cases with TEL/PDGFRB fusion gene, 2 cases with HEPI/PDGFRB, 1 case with PDGFRB mutation, 1 case with RABAPTIN-5/PDGFRB, 1 case with GIT2/PDGFRB, 1 case with TP53/PDGFRB, 1 case with WDR43/PDGFRB fusion gene were detected, showing the polymorphism of PDGFRB gene abnormalities. Among this kind of myeloid neoplasm patients, almost all patients manifested monocytosis and eosinophilia in different degree, the thrombocytosis mainly was observed in atypical myeloid neoplasms, acute leukemia, chromic myelo-monocytic leukemia patients. The treatment with imatinib mesylate for this kind of patients was effective in some cases. It is concluded that the myeloid neoplasms with PDGFRB gene abnormalities are a kind of heterogenetic myeloid neoplasms, their gene abnormal types and clinical manifestations show polymorphism too. The monocytosis and eosinophilia appear in this kind myeloid neoplasms which may be treated with tyrosine kinase inhibitors such as imatinib mesylate.

    Transcranial Doppler can detect microembolic signals, which are characterized by unidirectional high intensity increase, short duration, and random occurrence, producing a "whistling" sound. Microembolic signals have been proven to represent solid or gaseous particles within the blood flow. Microemboli have been detected in a number of clinical cardiovascular settings: carotid artery stenosis, aortic arch plaques, atrial fibrillation, myocardial infarction, prosthetic heart valves, patent foramen ovale, valvular stenosis, during invasive procedures (angiography, percutaneous transluminal angioplasty) and surgery (carotid, cardiopulmonary bypass). Despite numerous studies performed so far, clinical significance of microembolic signals is still unclear. This article provides an overview of the development and current state of technical and clinical aspects of microembolus detection.

    Full Text Available BACKGROUND: Abnormal posture (AP is often seen in Parkinson's disease (PD, and marked forms known as dropped head syndrome and camptocormia encumber daily living activities. Unlike other motor disabilities such as bradykinesia or muscular rigidity, AP is not always improved but rather deteriorated by PD medication. PURPOSE: To clarify factors associated with neck and thoracolumbar AP. METHODS: Neck flexion (NF and thoracolumbar (TL angles were measured in 216 consecutive PD patients and 175 elderly healthy controls. The differences in NF and TL angles between PD patients and controls were designated as ΔNFA and ΔTLA, respectively. The association of ΔNFA or ΔTLA and predictable factors such as age, sex, duration of PD, Hoehn Yahr (H-Y stage, Unified Parkinson's Disease Rating Scale Part 3 (UPDRS-3, daily dose of dopamine agonists, and comorbid orthopedic spinal lesions was investigated in PD patients. Patients were divided into quartiles according to ΔNFA or ΔTLA. The association between predictable factors and ΔNFA or ΔTLA was estimated as odds ratio (OR, comparing with the lowest quartile as the reference by multivariate regression analysis. RESULTS: Compared with controls, distributions of all three posture angles were significantly shifted rightward in PD patients. Although there were no difference in UPDRS-3 scores in the quartiles of ΔNFA, the highest quartile was associated with H-Y stage ≥3 [OR 2.99, 95% confidence interval (CI 1.33-6.70, p = 0.008] after adjustment for age, sex and comorbid orthopedic spinal lesions. The highest quartile of ΔTLA was associated with comorbid orthopedic spinal lesions [OR 5.83 (1.42-23.8, p = 0.014], and UPDRS-3 score [OR 3.04 (1.80-5.15/10 points, p<0.0001]. CONCLUSION: Thoraco-lumbar AP was associated with UPDRS-3 scores and orthopedic spinal lesions, and in contrast, neck AP was not associated with these factors, suggesting that they had different pathomechanisms.

    In the past decade, significant strides have been made in the area of cardiovascular pharmacogenomic research, with the discovery of associations between certain genotypes and drug-response phenotypes. While the motivations for personalized and predictive medicine are promising for patient care and support a model of health system efficiency, the implementation of pharmacogenomics for cardiovascular therapeutics on a population scale faces substantial challenges. The greatest obstacle to clinical implementation of cardiovascular pharmacogenetics may be the lack of both reproducibility and agreement about the validity and utility of the findings. In this review, we present the scientific evidence in the literature for diagnostic variants for the US FDA-labeled cardiovascular therapies, namely CYP2C19 and clopidogrel, CYP2C9/VKORC1 and warfarin, and CYP2D6/ADRB1 and β-blockers. We also discuss the effect of HMGCR/LDLR in decreasing the effectiveness of low-density lipoprotein cholesterol with statin therapy, the SLCO1B1 genotype and simvastatin myotoxicity, and ADRB1/ADD1 for antihypertensive response.

    Many of the structures and parameters that are detected, measured and reported in cardiovascular magnetic resonance (CMR) have at least some properties that are fractal, meaning complex and self-similar at different scales. To date however, there has been little use of fractal geometry in CMR; by comparison, many more applications of fractal analysis have been published in MR imaging of the brain.This review explains the fundamental principles of fractal geometry, places the fractal dimension into a meaningful context within the realms of Euclidean and topological space, and defines its role in digital image processing. It summarises the basic mathematics, highlights strengths and potential limitations of its application to biomedical imaging, shows key current examples and suggests a simple route for its successful clinical implementation by the CMR community.By simplifying some of the more abstract concepts of deterministic fractals, this review invites CMR scientists (clinicians, technologists, physicists) to experiment with fractal analysis as a means of developing the next generation of intelligent quantitative cardiac imaging tools.

    Full Text Available Korff Krause, Carsten Schneider, Kai Jaquet, Karl-Heinz KuckHanseatic Heart Center Hamburg, Department of Cardiology, Asklepios Hospital St. Georg, Hamburg, GermanyAbstract: The recent identification of bone marrow-derived adult stem cells and other types of stem cells that could improve heart function after transplantation have raised high expectations. The basic mechanisms have been studied mostly in murine models. However, these experiments revealed controversial results on transdifferentiation vs transfusion of adult stem cells vs paracrine effects of these cells, which is still being debated. Moreover, the reproducibility of these results in precisely translated large animal models is still less well investigated. Despite these weaknesses results of several clinical trials including several hundreds of patients with ischemic heart disease have been published. However, there are no solid data showing that any of these approaches can regenerate human myocardium. Even the effectiveness of cell therapy in these approaches is doubtful. In future we need in this important field of regenerative medicine: i more experimental data in large animals that are closer to the anatomy and physiology of humans, including data on dose effects, comparison of different cell types and different delivery routes; ii a better understanding of the molecular mechanisms involved in the fate of transplanted cells; iii more intensive research on genuine regenerative medicine, applying genetic regulation and cell engineering.Keywords: stem cells, cardiovascular disease

    Our research focuses on microphysiological aspects of the cardiovascular system, with an emphasis on what is occurring in heart tissues, to learn more about how various diseases arise and how they can be avoided or cured. These diseases include atherosclerosis, diabetes, myocardial infarction, obesity and ischemia/reperfusion (I/R). We use animal models, particularly mice, to aid us in these studies. A key feature of our work centers on dissection of coronary arterioles and examining their functionality using drugs, electrophysiology, fluoroscopy, genomics, proteomics, and standard chemical analyses to determine their physiological status, and compare it with other treated animals. My laboratory is focusing on anti-inflammatory and antioxidative stress therapeutic effects, the roles of sodium salicylate, exercise and resveratrol in type 2 diabetes, I/R injury, obesity, and atherosclerosis. Recently, we began investigations of the effects of stem cells and gastric bypass surgery on vascular dysfunction in obesity and diabetes. Our work identifies how diet, exercise, surgical interventions and drugs can be considered to combat these diseases in a clinical setting.

    To explore hemorrhage risk and the clinical significance of abnormal change of prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (FIB), plasma thrombin time (TT) and d-dimer (D-D) in de novo acute leukemia (except for APL), the different bleeding manifestations of 114 cases of de novo acute leukemia with different coagulation indexes were analyzed retrospectively. The correlation between these blood coagulation indexes and the possible correlative clinical characteristics were analysed, including age, sex, type of acute leukemia, initial white blood cell(WBC) and platelet(Plt) count, the proportion of blast cells in bone marrow and cytogenetic abnormality of patients at diagnosis. The results indicated that the incidence of abnormal blood coagulation was as high as 78.1% for de novo AL patients. These patients with 5 normal blood coagulation indexes may have mild bleeding manifestation, but the more abnormal indexes, the more severe bleeding. Both PT and D-D were sensitive indexes for diagnosis of level II bleeding. Incidence of abnormal blood coagulation significantly correlates with the proportion of blast cells in bone marrow (χ(2) = 4.184, OR = 1.021, P coagulation. It is concluded that the coagulation and fibrinolysis are abnormal in most patients with de novo acute leukemia. More abnormal indexes indicate more severe bleeding, and both PT and D-D are sensitive indexes for diagnosis of level II bleeding. Higher proportion of blast cells in bone marrow predicts higher incidence of abnormal blood clotting. Acute leukemia with elderly age, high white blood cell count and adverse cytogenetics do not predict severer abnormal blood clotting. Detection of PT, APTT, TT, FIB, and D-D may help to judge whether the patients are in a state of hypercoagulability or disseminated intravenous coagulation, which will provide experiment evidences for early intervention and medication.

    Full Text Available Abstract The existence of effective therapies for most cardiovascular disease states, coupled with increased requirements that potential benefits of new drugs be evaluated on clinical rather than surrogate endpoints, makes it increasingly difficult to substantiate any incremental improvements in efficacy that these new drugs might offer. Compounding the problem is the highly controversial issue of comparing new agents with placebos rather than active pharmaceuticals in drug efficacy trials. Despite the recent consensus that placebos may be used ethically in well-defined, justifiable circumstances, the problem persists, in part because of increased scrutiny by ethics committees but also because of considerable lingering disagreement regarding the propriety and scientific value of placebo-controlled trials (and trials of antihypertensive drugs in particular. The disagreement also substantially affects the most viable alternative to placebo-controlled trials: actively controlled equivalence/noninferiority trials. To a great extent, this situation was prompted by numerous previous trials of this type that were marked by fundamental methodological flaws and consequent false claims, inconsistencies, and potential harm to patients. As the development and use of generic drugs continue to escalate, along with concurrent pressure to control medical costs by substituting less-expensive therapies for established ones, any claim that a new drug, intervention, or therapy is "equivalent" to another should not be accepted without close scrutiny. Adherence to proper methods in conducting studies of equivalence will help investigators to avoid false claims and inconsistencies. These matters will be addressed in the third article of this three-part series.

    Full Text Available Micha T Maeder,1 Otto D Schoch,2 Hans Rickli1 1Department of Cardiology, 2Department of Respiratory Medicine, Kantonsspital St Gallen, St Gallen, Switzerland Abstract: Obstructive sleep apnea (OSA is associated with cardiovascular risk factors, cardiovascular diseases, and increased mortality. Epidemiological studies have established these associations, and there are now numerous experimental and clinical studies which have provided information on the possible underlying mechanisms. Mechanistic proof-of-concept studies with surrogate endpoints have been performed to demonstrate that treatment of OSA by continuous positive airway pressure (CPAP has the potential to reverse or at least to attenuate not only OSA but also the adverse cardiovascular effects associated with OSA. However, no randomized studies have been performed to demonstrate that treatment of OSA by CPAP improves clinical outcomes in patients with cardiovascular risk factors and/or established cardiovascular disease and concomitant OSA. In the present review, we summarize the current knowledge on the role of OSA as a potential cardiovascular risk factor, the impact of OSA on cardiac function, the role of OSA as a modifier of the course of cardiovascular diseases such as coronary artery disease, atrial fibrillation, and heart failure, and the insights from studies evaluating the impact of CPAP therapy on the cardiovascular features associated with OSA.

    The aim of this study was to investigate the clinical and laboratorial characteristics of splenic marginal zone lymphoma (SMZL) with an abnormal complete blood count (CBC). Data of 19 newly diagnosed SMZL patients with abnormal CBC were analyzed retrospectively. Seven patients were diagnosed by using splenic histology, 12 patients who did not undergo splenectomy were diagnosed on the basis of typical clinical presentation and cytologic, immunophenotypic and histologic characteristics of peripheral blood and bone marrow, according to SBLG guidelines. The results showed that leukocytosis (≥ 10.0×10(9)/L) was seen in 5 cases (26.3%); leukocytopenia (complete response was achieved in 9 out of 11 (81.8%) patients. It is concluded that SMZL with abnormal CBC has a higher incidence of cytopenia, bone marrow involvement and autoimmune phenomena. Therapeutic strategies consisting of Rituximab show a better efficacy.

    We need to find novel ways of increasing exercise participation, particularly in those populations who find it difficult to participate in voluntary exercise. In recent years researchers have started to investigate the potential for using electrical stimulation to artificially stimulate a pattern of muscle activity that would induce a physiological response consistent with cardiovascular exercise. Work to date has indicated that this is best achieved by using a stimulation protocol that results in rapid rhythmical isometric contractions of the large leg muscle groups at sub tetanic frequencies. Studies completed by our group indicate that this technique can serve as a viable alternative to voluntary cardiovascular exercise. Apart from being able to induce a cardiovascular exercise effect in patient populations (e.g. heart failure, COPD, spinal cord injury, obesity), this approach may also have value in promotion of exercise activity in a microgravity environment.

Eighteen postmenopausal obese women with MetS (age, 54.8 ± 8.4 years; height, 160 ± 6 cm followed a 12-week training program consisting of three 45-minute sessions/wk on a cycle ergometer. The intensity imposed during the training sessions corresponded to COP. Before and after the training program, anthropometric, biological, and blood pressure data were collected and compared. After the training program, body mass (88.4 ± 12.3 kg vs. 85.7 ± 11.1 kg, fat mass (43.2 ± 4.8% vs. 41.8 ± 4.8% body mass, body mass index (34.3 ± 3.9 kg/m2 vs. 33.2 ± 3.6 kg/m2, and waist circumference (105 ± 10 cm vs. 100 ± 9 cm were significantly lower (p < 0.01. Moreover, fasting plasma glucose was significantly lower after the training program (114 ± 20 mg/dL vs. 107 ± 15 mg/dL; p = 0.02 and the quantitative insulin-sensitivity check index was significantly higher (0.58 ± 0.08 vs. 0.61 ± 0.05; p = 0.05. A significant reduction in systolic blood pressure was also observed (141 ± 15 mmHg vs. 129 ± 11 mmHg; p = 0.02. After the program, the number of patients with fasting plasma hyperglycemia and arterial hypertension was significantly decreased by 54.4% and 44.4%, respectively, and the number of patients with MetS was nonsignificantly reduced by 22.2% (p = 0.10. The present study shows that a training program at COP is an efficient means to treat MetS.

  8. Long Pentraxin 3: Experimental and Clinical Relevance in Cardiovascular Diseases

    Directory of Open Access Journals (Sweden)

    Fabrizia Bonacina

    2013-01-01

    Full Text Available Pentraxin 3 (PTX3 is an essential component of the humoral arm of innate immunity and belongs, together with the C-reactive protein (CRP and other acute phase proteins, to the pentraxins' superfamily: soluble, multifunctional, pattern recognition proteins. Pentraxins share a common C-terminal pentraxin domain, which in the case of PTX3 is coupled to an unrelated long N-terminal domain. PTX3 in humans, like CRP, correlates with surrogate markers of atherosclerosis and is independently associated with the risk of developing vascular events. Studies addressing the potential physiopathological role of CRP in the cardiovascular system were so far inconclusive and have been limited by the fact that the sequence and regulation have not been conserved during evolution between mouse and man. On the contrary, the conservation of sequence, gene organization, and regulation of PTX3 supports the translation of animal model findings in humans. While PTX3 deficiency is associated with increased inflammation, cardiac damage, and atherosclerosis, the overexpression limits carotid restenosis after angioplasty. These observations point to a cardiovascular protective effect of PTX3 potentially associated with the ability of tuning inflammation and favor the hypothesis that the increased levels of PTX3 in subjects with cardiovascular diseases may reflect a protective physiological mechanism, which correlates with the immunoinflammatory response observed in several cardiovascular disorders.

    The metabolic syndrome is a condition characterized by a special constellation of reversible major risk factors for cardiovascular disease and type 2 diabetes. The main, diagnostic, components are reduced HDL-cholesterol, raised triglycerides, blood pressure and fasting plasma glucose, all of which are related to weight gain, specifically intra-abdominal/ectopic fat accumulation and a large waist circumference. Using internationally adopted arbitrary cut-off values for waist circumference, having metabolic syndrome doubles the risk of cardiovascular disease, but offers an effective treatment approach through weight management. Metabolic syndrome now affects 30-40% of people by age 65, driven mainly by adult weight gain, and by a genetic or epigenetic predisposition to intra-abdominal/ectopic fat accumulation related to poor intra-uterine growth. Metabolic syndrome is also promoted by a lack of subcutaneous adipose tissue, low skeletal muscle mass and anti-retroviral drugs. Reducing weight by 5-10%, by diet and exercise, with or without, anti-obesity drugs, substantially lowers all metabolic syndrome components, and risk of type 2 diabetes and cardiovascular disease. Other cardiovascular disease risk factors such as smoking should be corrected as a priority. Anti-diabetic agents which improve insulin resistance and reduce blood pressure, lipids and weight should be preferred for diabetic patients with metabolic syndrome. Bariatric surgery offers an alternative treatment for those with BMI ≥ 40 or 35-40 kg/m(2) with other significant co-morbidity. The prevalence of the metabolic syndrome and cardiovascular disease is expected to rise along with the global obesity epidemic: greater emphasis should be given to effective early weight-management to reduce risk in pre-symptomatic individuals with large waists.

We aimed to determine the clinical features that are most likely to be associated with abnormal CT scan in patients with a history of head injury, and who are conscious at the time of presentation to casualty. Materials and Methods: This is a prospective observation study of patients presented to casualty with history of head injury, and who were conscious, i.e., Glasgow Coma Scale (GCS 15 at the time of evaluation. All patients underwent head CT scan. The CT scan was reported as abnormal if it showed any pathology ascribed to trauma. The following variables were used: age, gender, mode of injury (road traffic accident, fall, assault, and others, duration since injury, and history of transient loss of consciousness, headache, vomiting, ear/nose bleeding, and seizures. Logistic regression analysis was used to identify the clinical features that predicted an abnormal CT scan. Results: During the observation period, a total of 1629 patients with head injury were evaluated, out of which 453 were in GCS 15. Abnormal CT scan was present in 195 (43% patients. Among all the variables, the following were found significantly associated with abnormal CT scan: duration since injury (>12 h P< 0.001; vomiting odds, ratio (OR 1.89 (1.23, 2.80, P< 0.001; and presence of any symptom, OR 2.36 (1.52, 3.71, P< 0.001. Conclusion: A patient with GCS 15 presenting after 12 hours of injury with vomiting or combination of symptoms has a significant risk of abnormal head CT scan.

    Full Text Available Kelly C Pearson1, April W Armstrong21Chicago Medical School, Rosalind Franklin University of Medicine and Science, North Chicago, IL, 2Department of Dermatology, University of California, Davis, Sacramento, CA, USAAbstract: Psoriasis is a systemic inflammatory disorder, which has been reported to be associated with adverse cardiovascular (CV risks. CV comorbidities, such as diabetes, dyslipidemia, hypertension, and obesity appear to be increased in psoriasis patients compared with the general population. Psoriasis may contribute independently to adverse cardiac outcomes after accounting for traditional CV risk factors. In this article, it was aimed to summarize large population studies that examine the relationship between psoriasis and CV risk factors and major adverse cardiac outcomes, and highlight proposed mechanisms for the observed epidemiologic link. Specifically, large population-based studies with over 1000 total subjects from 1975 to September 2008 in the English literature are highlighted. The relevant search terms in the Ovid Medline database were applied. The majority of the studies presented evidence for an increased incidence of CV risk factors and an increased risk for major adverse cardiac outcomes in patients with severe psoriasis. The increased risk in severe psoriasis necessitates regular screening for other comorbidities. Current guidelines for screening CV risk factors among psoriasis patients are discussed. Also reviewed is the scarce literature in therapeutic strategies to reduce CV risk factors and major adverse cardiac outcomes in psoriasis patients. Specifically, an emerging area of research on the effects of biologic agents on CV risk factors and CV adverse outcomes in psoriasis is discussed.Keywords: cardiovascular disease, cardiovascular risk factors, psoriasis, diabetes mellitus, myocardial infarction, major adverse cardiovascular events, MACE, hypertension

    Full Text Available Cardiovascular biomaterials (CB dominate the category of biomaterials based on the demand and investments in this field. This review article classifies the CB into three major classes, namely, metals, polymers, and biological materials and collates the information about the CB. Blood compatibility is one of the major criteria which limit the use of biomaterials for cardiovascular application. Several key players are associated with blood compatibility and they are discussed in this paper. To enhance the compatibility of the CB, several surface modification strategies were in use currently. Some recent applications of surface modification technology on the materials for cardiovascular devices were also discussed for better understanding. Finally, the current trend of the CB, endothelization of the cardiac implants and utilization of induced human pluripotent stem cells (ihPSCs, is also presented in this review. The field of CB is growing constantly and many new investigators and researchers are developing interest in this domain. This review will serve as a one stop arrangement to quickly grasp the basic research in the field of CB.

One-year follow-up was carried out and post-ischemic epilepsy was diagnosed.  Results Among 162 ischemic stroke patients, 24-hour EEG was abnormal in 87 cases (53.70%. According to the correspondence of site of infarcts and abnormal discharges, these 87 cases were classified into 2 groups: matched group (N = 24, 27.59% and unmatched group (N = 63, 72.41%. There was no significant difference between 2 groups in terms of Oxfordshire Community Stroke Project (OCSP and TOAST classification (P = 0.792, 0.111, while there was significant difference between 2 groups on the site of infarcts (P = 0.000. In matched group, the infarcts were mainly located in cortex (N = 23, 95.83%. However, in unmatched group, the infarcts were mainly located in cortex and basal ganglia (N = 27, 42.86%, or in basal ganglia only (N = 24, 38.10%. In matched group, 24-hour EEG showed slowing of background activities, and sharp waves and sharp and slow wave complex which were corresponding to the infarct sites. The abnormal discharges could only be recorded around the infarct unilaterally. In unmatched group, the epileptiform discharges were recorded in both contralateral and ipsilateral ischemic hemispheres, usually with widespread slow waves and asymmetric background. The infarcts were limited, but abnormal discharges were widespread. For example, the infarct was located in deep brain, while scalp abnormal discharges were recorded. Although there was no significant difference in terms of epilepsy incidence between 2 groups (P = 0.908, the types of epilepsy were statistically different between 2 groups (P = 0.000. In matched group, the main type was partial seizure. But in unmatched group, the main types of epilepsy were secondary generalized seizure and

    2013-12-01

    Full Text Available Aim. The objective of this study is to determine whether and how metabolic abnormalities are associated with clinical symptoms and cognitive performance in schizophrenia. Methods. 46 adult patients with schizophrenia taking first- or second generation antipsychotics were included in the study. The following data were collected: BMI, abdominal circumference, lipid panel and blood glucose, blood pressure and treatment of comorbidities. Clinical symptoms were assessed using PANSS, CDSS, CGI and SAS scales. Cognitive performance was assessed using CNS Vital Signs computerized battery of tests: Verbal Memory test, Visual Memory test, Finger Tapping Test, Symbol Digit Coding, Stroop Test, Shifting Attention Test, and Continuous Performance Test. Results. Dyslipidemia, raised LDL and raised blood glucose levels were the best predictors of more severe clinical symptoms (PANSS, PANSS P, PANSS G, CGI and lower neurocognitive index, worse cognitive flexibility, executive functions, complex attention composite memory, verbal memory, slower reaction time and worse performance in SAT, CPT, ST tests. Obesity was associated with worse results in VBM, VIM, FTT, SDC tests. Raised blood pressure was associated with improvements in all cognitive domains and better performance in SAT, CPT, ST tests. Discussion. There are several weak associations between severity of clinical symptoms and metabolic abnormalities. Most of these were for blood glucose levels and raised blood glucose. Lipids and glucose abnormalities are the best predictors of deteriorated cognitive performance. Contrary to previous observations, raised blood pressure was associated with better results in cognitive tests. Conclusions. These findings indicate that cognitive impairment and metabolic abnormalities may be linked in patients with schizophrenia

    Full Text Available Background Minor head trauma accounts for 70% to 90% of all head traumas. Previous studies stated that minor head traumas were associated with 7% - 20% significant abnormal findings in brain computed tomography (CT-scans. Objectives The aim of this study was to reevaluate clinical criteria of taking brain CT scan in patients who suffered from minor head trauma. Patients and Methods We enrolled 680 patients presented to an academic trauma hospital with minor head trauma in a prospective manner. All participants underwent brain CT scan if they met the inclusion criteria and the results of scans were compared with clinical examination finding. Results Loss of consciousness (GCS drop or amnesia was markedly associated with abnormal brain CT scan (P < 0.05. Interestingly, we found 7 patients with normal clinical examination but significant abnormal brain CT scan. Conclusions According to the results of our study, we recommend that all patients with minor head trauma underwent brain CT scan in order not to miss any life-threatening head injuries.

    Full Text Available Background: To reduce the duration and overall costs of cardiovascular trials, use of the combined endpoints in trial design has become commonplace. Though this methodology may serve the needs of investigators and trial sponsors, the preferences of patients or potential trial subjects in the trial design process has not been studied. Objective: To determine the preferences of patients in the design of cardiovascular trials. Design: Participants were surveyed in a pilot study regarding preferences among various single endpoints commonly used in cardiovascular trials, preference for single vs. composite endpoints, and the likelihood of compliance with a heart medication if patients similar to them participated in the trial design process. Participants: One hundred adult English-speaking patients, 38% male, from a primary care ambulatory practice located in an urban setting. Key results: Among single endpoints, participants rated heart attack as significantly more important than death from other causes (4.53 vs. 3.69, p=0.004 on a scale of 1–6. Death from heart disease was rated as significantly more important than chest pain (4.73 vs. 2.47, p<0.001, angioplasty/PCI/CABG (4.73 vs. 2.43, p<0.001, and stroke (4.73 vs. 2.43, p<0.001. Participants also expressed a slight preference for combined endpoints over single endpoint (43% vs. 57%, incorporation of the opinions of the study patient population into the design of trials (48% vs. 41% for researchers, and a greater likelihood of medication compliance if patient preferences were considered during trial design (67% indicated a significant to major effect. Conclusions: Patients are able to make judgments and express preferences regarding trial design. They prefer that the opinions of the study population rather than the general population be incorporated into the design of the study. This novel approach to study design would not only incorporate patient preferences into medical decision making, but

    With the decline of ovarian hormonal function, from the fifth decade of life, women enter the menopause transition, during which bleeding becomes irregular in duration and time of occurrence. Secondary to ovarian dysfunction, developmental and maturation endometrial anomalies occur, which are clinically translated by abnormal uterine bleeding, which in many cases at this age can be caused by organic lesions (fibroma, polyps, endometritis, endometrial hyperplasia, adenomyosis, etc.). The retrospective study included a total of 256 patients with abnormal uterine bleeding in menopause transition. Statistics showed that the incidence of these types of bleeding increases with age (64.5%) and parity (30.5%), with symptoms consisting mostly in different clinical forms of abnormal uterine bleeding (62.1%), and leiomyomas prevailing at histopathological examination (49.6%). Progesterone replacement therapy was the first therapeutic choice for correcting these types of bleeding. Progesterone therapy is useful not only for therapeutic purposes to amend the bleeding, but also as a precaution against the development of endometrial carcinoma. Progestogens cancel the proliferative and mitogenic effect of estrogens, even when administered in sequential regimen 10-12 days per month.

    Team-based cardiovascular care, including the use of clinical pharmacists, can efficiently deliver high-quality care. This Joint Council Perspectives paper from the Cardiovascular Team and Prevention Councils of the American College of Cardiology provides background information on the clinical pharmacist's role, training, certification, and potential utilization in a variety of practice models. Selected systematic reviews and meta-analyses, highlighting the benefit of clinical pharmacy services, are summarized. Clinical pharmacists have a substantial effect in a wide variety of roles in inpatient and ambulatory settings, largely through optimization of drug use, avoidance of adverse drug events, and transitional care activities focusing on medication reconciliation and patient education. Expansion of clinical pharmacy services is often impeded by policy, legislation, and compensation barriers. Multidisciplinary organizations, including the American College of Cardiology, should support efforts to overcome these barriers, allowing pharmacists to deliver high-quality patient care to the full extent of their education and training.

    Full Text Available Clinical pharmacy is deemed an integral component of a health care system. The presence of clinical pharmacists in medical rounds could assist physicians in optimizing patients pharmacotherapy. Moreover, clinical pharmacists may reduce adverse effects and medication errors insofar as they contribute significantly to the detection and management of drug-related problems, not least in patients with cardiovascular diseases, who have the highest rank in the frequency of medication errors. Clinical pharmacists can also collaborate with physicians in the management of cardiovascular risk factors as well as anticoagulation therapy based on patients specific situations. In summary, the practice of clinical pharmacy is considered a crucial part of a health care team to improve the level of patients care by increasing the quality of therapy with the least expense for a health care system.

    A substantial need to conduct research studies and identify effective treatments for cardiovascular diseases in the developing world exists. Careful consideration of several issues is warranted to ensure that clinical trials conducted solely in developing nations are held to accepted scientific standards. Researchers conducting clinical trials in developing countries should critically evaluate the purpose and appropriateness of conducting the trial in the proposed location, the accessibility of the therapy if proven effective, the quality of the informed consent process, the presence of infrastructure to support clinical research, and the translation of data to other populations. This article discusses the importance of these considerations using a recent example of a clinical trial conducted in a developing nation. These and other issues are critical to address as the conduct of cardiovascular clinical trials continues to expand beyond the western world.

The aim of this study was to gain appropriate knowledge in the epidemiology of co-morbid depression and anxiety disorder in cardiovascular outpatients.Method: This study is descriptive with a sample of patients attending a cardio-vascular clinic. 238 individuals were included in this study using a consecutive sampling method. The study instrument was Hospital Anxiety and Depression Scale (HADS questionnaire, which is a clinical scale for assessing anxiety and depression.Results: Of the 238 participants in this study, 93(38.7% were male and 146 (61.3% female. 28.5% of patients suffered from anxiety disorders , and 41.9% had depression. Regarding comorbid diseases such as diabetes mellitus, hyperlipidemia and hypertension, the severity of depression was just related to hypertension. There was a meaningful relationship between gender and symptoms of anxiety so that symptoms were more severe in women. Conclusion: Considering the high prevalence of depression and anxiety in patients suffering from cardio-vascular diseases, it is necessary to screen psychological disorders in patients with cardio-vascular diseases and improve their cardio-vascular health and quality of life as mush as possible.

    We present our experience in 18 pediatric patients with abnormal neuronal migration. Seven cases of heterotopia of the gray matter, 7 agyria-pachygyria complexes, 1 case of polymicrogyria, 2 cases of schizencephaly and 1 case of hemimegalencephaly were diagnosed by means of ultrasonography, computed tomography and magnetic resonance. The clinical picture was reviewed in each case, with special attention to the occurrence of convulsions, psycho motor development and visual changes. In general, the greater the morphological change, the greater the neurological involvement in these patients. However, the two cases of schizencephaly presented mild clinical expression. Magnetic resonance increases the diagnostic yield in neuronal migration disorders. Nevertheless, either ultrasonography or, especially, computed tomography is useful as a first diagnostic approach in these malformative disorders. (Author)

    Callosal anomalies are frequently associated with other central nervous system (CNS) and/or somatic anomalies. We retrospectively analyzed the clinical features of corpus callosal agenesis/hypoplasia accompanying other CNS and/or somatic anomalies. We reviewed the imaging and clinical information of patients who underwent brain magnetic resonance imaging in our hospital, between 2005 and 2012. Callosal anomalies were isolated in 13 patients, accompanied by other CNS anomalies in 10 patients, associated with only non-CNS somatic anomalies in four patients, and with both CNS and non-CNS abnormalities in four patients. Out of 31 patients, four developed normally, without impairments in motor or cognitive functions. Five of nine patients with cerebral palsy were accompanied by other CNS and/or somatic anomalies, and showed worse Gross Motor Function Classification System scores, compared with the other four patients with isolated callosal anomaly. In addition, patients with other CNS anomalies also had a higher seizure risk.

    Brain death is defined as the permanent, irreversible and concurrent loss of all brain and brain stem functions. Brain death diagnosis is based on clinical criteria and it is not routine to use paraclinical studies. In some countries, electroencephalogram (EEG) is performed in all patients for the determination of brain death while there is some skepticism in relying on EEG as a confirmatory test for brain death diagnosis. In this study, we assessed the validity of EEG and its abnormalities in brain death diagnosis. In this retrospective study, we used 153 EEGs from medical records of 89 brain death patients in organ procurement unit of the Iranian Tissue Bank admitted during 2002-2008. We extracted and analyzed information including EEGs, which were examined by a neurologist for waves, artifacts and EEG abnormalities. The mean age of the patients was 27.2±12.7 years. The most common cause of brain death was multiple traumas due to accident (65%). The most prevalent artifact was electrical transformer. 125 EEGs (82%) were isoelectric (ECS) and seven EEGs (5%) were depictive of some cerebral activity which upon repeat EEGs, they showed ECS patterns too. There was no relationship between cause of brain death and cerebral activity in EEGs of the patients. In this study, we could confirm ECS patterns in all brain death patients whose status had earlier been diagnosed clinically. Considering the results of this study, it seems sensible to perform EEG as a final confirmatory test as an assurance to the patients' families.

    A thorough understanding of developmental cardiovascular physiology is essential for early recognition of cardiovascular compromise, selective screening of at-risk groups of neonates, and individualized management using pathophysiology-targeted interventions. Although we have gained a better understanding of the physiology and pathophysiology of postnatal cardiovascular transition over the past decade with the use of sophisticated methods to study neonatal hemodynamics, most aspects of neonatal hemodynamics remain incompletely understood. In addition, targeted therapeutic interventions of neonatal hemodynamic compromise have not been shown to improve mortality and clinically relevant outcomes. However, the recent development of comprehensive hemodynamic monitoring systems capable of non-invasive, continuous and simultaneous bedside assessment of cardiac output, organ blood flow, microcirculation, and tissue oxygen delivery has made sophisticated analysis of the obtained physiologic data possible and has created new research opportunities with the potential of direct implications to patient care.

    Full Text Available Scorpionism is a common problem that occurs in tropical and subtropical countries and assumes great medical-sanitary importance due to its fatal effect on sensitive individuals, being able to lead children and aged people to death. The envenomation lethal potential is responsible for the serious cardiopulmonary alterations the scorpion toxin produces in its victims. The present research evaluated the effects of Tityus serrulatus venom on dogs, using two distinct doses: a dose that simulates natural envenomation (0.4 mg/total dose, and an experimental dose (0.25 mg/kg. General clinical signs were observed at different moments after envenomation, and specific data related to the cardiopulmonary system were evaluated by systemic arterial pressure measurement, CK-MB enzymatic activity dosage, and radiographic, electrocardiographic and echocardiographic examinations. Results demonstrated that the scorpion venom, in experimental doses, was able to cause acute and reversible cardiac injury in few days, and, in the dose that simulated natural accident, it produced clinical signs of light envenomation, such as local pain, hyperesthesia, sialorrhea, vomiting, diarrhea, sneeze and prostration.

Aberrant sympathetic nervous system expression may result in elevated HR or decreased HR variability, and both are independent risk factors for development of cardiovascular disease, including heart failure, myocardial infarction, and hypertension. Epidemiologic studies have established that impaired HR control is linked to increased cardiovascular morbidity and mortality. One successful way of decreasing HR and cardiovascular mortality has been by utilizing β-blockers, because their ability to alter cell signaling at the receptor level has been shown to mitigate the pathogenic effects of sympathetic nervous system hyperactivation. Numerous clinical studies have demonstrated that β-blocker-mediated HR control improvements are associated with decreased mortality in postinfarct and heart failure patients. Although improved HR control benefits have yet to be established in hypertension, both traditional and vasodilating β-blockers exert positive HR control effects in this patient population. However, differences exist between traditional and vasodilating β-blockers; the latter reduce peripheral vascular resistance and exert neutral or positive effects on important metabolic parameters. Clinical evidence suggests that attainment of HR control is an important treatment objective for patients with cardiovascular

  20. Cardiovascular effects of dipeptidyl peptidase-4 inhibitors: from risk factors to clinical outcomes.

    Science.gov (United States)

    Scheen, André J

    2013-05-01

    Dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) are oral incretin-based glucose-lowering agents with proven efficacy and safety in the management of type 2 diabetes mellitus (T2DM). In addition, preclinical data and mechanistic studies suggest a possible additional non-glycemic beneficial action on blood vessels and the heart, via both glucagon-like peptide-1-dependent and glucagon-like peptide-1-independent effects. As a matter of fact, DPP-4 inhibitors improve several cardiovascular risk factors: they improve glucose control (mainly by reducing the risk of postprandial hyperglycemia) and are weight neutral; may lower blood pressure somewhat; improve postprandial (and even fasting) lipemia; reduce inflammatory markers; diminish oxidative stress; improve endothelial function; and reduce platelet aggregation in patients with T2DM. In addition, positive effects on the myocardium have been described in patients with ischemic heart disease. Results of post hoc analyses of phase 2/3 controlled trials suggest a possible cardioprotective effect with a trend (sometimes significant) toward lower incidence of major cardiovascular events with sitagliptin, vildagliptin, saxagliptin, linagliptin, or alogliptin compared with placebo or other active glucose-lowering agents. However, the definite relationship between DPP-4 inhibition and better cardiovascular outcomes remains to be proven. Major prospective clinical trials involving various DPP-4 inhibitors with predefined cardiovascular outcomes are under way in patients with T2DM and a high-risk cardiovascular profile: the Sitagliptin Cardiovascular Outcome Study (TECOS) on sitagliptin, the Saxagliptin Assessment of Vascular Outcomes Recorded in Patients With Diabetes Mellitus-Thrombolysis in Myocardial Infarction (SAVOR-TIMI) 53 trial on saxagliptin, the Cardiovascular Outcomes Study of Alogliptin in Subjects With Type 2 Diabetes and Acute Coronary Syndrome (EXAMINE) trial on alogliptin, and the Cardiovascular Outcome

    In this paper we comprehensively review published quantitative research on the relationship between religion, spirituality (R/S), and cardiovascular (CV) disease, discuss mechanisms that help explain the associations reported, examine the clinical implications of those findings, and explore future research needed in Brazil on this topic. First, we define the terms religion, spirituality, and secular humanism. Next, we review research examining the relationships between R/S and CV risk factors (smoking, alcohol/drug use, physical inactivity, poor diet, cholesterol, obesity, diabetes, blood pressure, and psychosocial stress). We then review research on R/S, cardiovascular functions (CV reactivity, heart rate variability, etc.), and inflammatory markers (IL-6, IFN-γ, CRP, fibrinogen, IL-4, IL-10). Next we examine research on R/S and coronary artery disease, hypertension, stroke, dementia, cardiac surgery outcomes, and mortality (CV mortality in particular). We then discuss mechanisms that help explain these relationships (focusing on psychological, social, and behavioral pathways) and present a theoretical causal model based on a Western religious perspective. Next we discuss the clinical applications of the research, and make practical suggestions on how cardiologists and cardiac surgeons can sensitively and sensibly address spiritual issues in clinical practice. Finally, we explore opportunities for future research. No research on R/S and cardiovascular disease has yet been published from Brazil, despite the tremendous interest and involvement of the population in R/S, making this an area of almost unlimited possibilities for researchers in Brazil.

    Heart rate variability (HRV) has been conventionally analysed with time- and frequency-domain methods, which measure the overall magnitude of RR interval fluctuations around its mean value or the magnitude of fluctuations in some predetermined frequencies. Analysis of heart rate dynamics by novel methods, such as heart rate turbulence after ventricular premature beats, deceleration capacity of heart rate and methods based on chaos theory and nonlinear system theory, have gained recent interest. Recent observational studies have suggested that some indices describing nonlinear heart rate dynamics, such as fractal scaling exponents, heart rate turbulence and deceleration capacity, may provide useful prognostic information in various clinical settings and their reproducibility may be better than that of traditional indices. For example, the short-term fractal scaling exponent measured by the detrended fluctuation analysis method has been shown to predict fatal cardiovascular events in various populations. Similarly, heart rate turbulence and deceleration capacity have performed better than traditional HRV measures in predicting mortality in post-infarction patients. Approximate entropy, a nonlinear index of heart rate dynamics, which describes the complexity of RR interval behaviour, has provided information on the vulnerability to atrial fibrillation. There are many other nonlinear indices which also give information on the characteristics of heart rate dynamics, but their clinical usefulness is not as well established. Although the concepts of nonlinear dynamics, fractal mathematics and complexity measures of heart rate behaviour, heart rate turbulence, deceleration capacity in relation to cardiovascular physiology or various cardiovascular events are still far away from clinical medicine, they are a fruitful area for research to expand our knowledge concerning the behaviour of cardiovascular oscillations in normal healthy conditions as well as in disease states.

    The aim of this retrospective study was to assess prevalence, risk factors, clinical presentation and outcome of phenobarbitone induced haematological abnormalities (PBIHA) in dogs. The medical records of two veterinary referral institutions were searched for dogs diagnosed with idiopathic epilepsy and treated with PB as monotherapy or polytherapy between March 2003 and September 2010. Sixteen dogs had PBIHA; the median age at diagnosis was 69.5 months. Phenobarbitone was administered at a median dose of 3 mg/kg twice a day for a median period of 100.5 days and the median serum phenobarbitone level was 19 μg/ml. Two dogs had neutropenia, three had anaemia and thrombocytopenia, two had anaemia and neutropenia; the remaining nine had pancytopenia. All dogs were referred for non-specific clinical signs. Phenobarbitone was discontinued after diagnosis, and the median time to resolution of PBIHA was 17 days. The prevalence and risk factors for PBIHA were evaluated from a questionnaire survey of referring practices to obtain more detailed follow-up on cases diagnosed with idiopathic epilepsy. The prevalence rate of PBIHA was 4.2%, and the condition occurred in dogs treated with standard therapeutic doses often within the first three months after starting treatment. Serial haematological evaluations should be therefore considered from the beginning of phenobarbitone therapy to allow early diagnosis and treatment of PBIHA.

    The clinical usefulness of plasma abnormal prothrombin, defined as a protein induced by vitamin K absence or antagonist-II: PIVKA-II, as a tumor marker for hepatocellular carcinoma (HCC), was evaluated. Plasma PIVKA-II concentration was determined by an enzyme-linked immunosorbent assay (ELISA) using a monoclonal antibody specific for PIVKA-II. Forty-one (65%) out of 63 patients with HCC had an abnormal PIVKA-II level above 0.13 arbitrary units (AU)/ml; the level was above 0.3 AU/ml in 33 patients (52%) and above 0.5 AU/ml in 27 patients (43%). On the other hand, most of the 282 patients with various liver diseases other than HCC had normal or slightly elevated levels of PIVKA-II. Their values were all below 0.5 AU/ml, with the exception of 2 patients with decompensated liver cirrhosis. The patients with PIVKA-II values above 0.5 AU/ml were strongly suspected of having HCC. Plasma PIVKA-II levels were not related to serum alpha-fetoprotein (AFP) levels, but were above 0.5 AU/ml in 14 (44%) out of the 32 patients whose serum AFP levels were below 400 ng/ml. In some patients with HCC, PIVKA-II was increased throughout the course of the disease, and in others it normalized after surgical resection of the tumor. We conclude that the plasma PIVKA-II assay by the ELISA method using a monoclonal antibody is a useful diagnostic tool for monitoring HCC, particularly in HCC patients with low AFP levels.

    (1) Autonomic dysfunction is a well recognised complication of diabetes mellitus and early detection may allow therapeutic manoeuvres to reduce the associated mortality and morbidity. We sought to identify early cardiovascular autonomic neuropathy using spectral analysis of heart rate and systolic blood pressure variability. (2) Thirty patients with Type 1 (insulin-dependent) diabetes mellitus (DM) and 30 matched control subjects were studied. In addition to standard tests of autonomic function, heart rate and systolic blood pressure variability were assessed using power spectral analysis. From the frequency domain analysis of systolic blood pressure and R-R interval, the overall gain of baroreflex mechanisms was assessed. (3) Standard tests of autonomic function were normal in both groups. Total spectral power of R-R interval was reduced in the Type 1 DM group for low-frequency (473 +/- 63 vs. 747 +/- 78 ms2, mean +/- S.E.M., P = 0.002) and high-frequency bands (125 +/- 13 vs. 459+/-90 ms2, P standing (2.9+/-0.9 vs. 7.18+/-1.9 ms/mmHg, P < 0.001). (4) Spectral analysis of cardiovascular variability detects autonomic dysfunction more frequently in Type 1 DM patients than conventional tests, and is suggestive of an abnormality of parasympathetic function. The abnormality of baroreceptor-cardiac reflex sensitivity could be explained by this impairment of parasympathetic function and this may predispose to the development of hypertension and increase the risk of sudden cardiac death. Using spectral analysis methods may allow detection of early diabetic cardiac autonomic neuropathy and allow therapeutic intervention to slow the progression.

    Full Text Available Evidence for the potential role of organ specific cardiovascular renin-angiotensin systems (RAS has been demonstrated experimentally and clinically with respect to certain cardiovascular and renal diseases. These findings have been supported by studies involving pharmacological inhibition during ischemic heart disease, myocardial infarction, cardiac failure; hypertension associated with left ventricular (LV ischemia, myocardial fibrosis and left ventricular hypertrophy (LVH; structural and functional changes of the target organs associated with prolonged dietary salt excess; and intrarenal vascular disease associated with end-stage renal disease (ESRD. Moreover, the severe structural and functional changes induced by these pathological conditions, can be prevented and reversed by agents producing RAS inhibition (even when not necessarily coincident with alterations in arterial pressure.In this review, we discuss specific fundamental and clinical aspects and mechanisms related to the activation or inhibition of local renin angiotensin systems and their implications for cardiovascular and renal diseases. Fundamental aspects involving the role of angiotensins on cardiac and renal functions including the expression of RAS components in the heart and kidney and the controversial role of ACE2 on angiotensin peptide metabolism in humans, were discussed.

    Full Text Available Background: Magnetic resonance imaging (MRI helps in the diagnosis of neurologic Wilson′s disease (WD. The literature regarding MR spectroscopy (MRS and diffusion-weighted imaging (DWI in WD is limited. Objectives: To evaluate the clinical features and neuroimaging findings in drug-naοve neurologic WD and to find correlation between clinical stage and disease duration with different imaging findings. Materials and Methods: The study subjects included consecutive and follow-up neurologic WD patients attending movement disorder clinic. The initial clinical and MRI features before commencement of chelation therapy were noted. Of 78 patients, 34 underwent DWI study and MRS was done in 38 patients and in 32 control subjects. Results: Dystonia, dysarthria, tremor, and behavioral abnormality were common presenting features. All patients had MRI abnormality with major affection of basal ganglia. The clinical severity and anatomical extent of MRI abnormalities were positively correlated (P < 0.001; r s = 0.709. Presence of diffusion restriction was inversely related to duration of disease (P < 0.001; r s = 0.760. WD patients had reduced N-acetylaspartate/creatine (Cr and choline (Cho/Cr ratio (P < 0.001 as compared with control subjects in MRS study. Conclusion: Dystonia, dysarthria and tremor are common neurological features of WD. In this study, MRI abnormalities were positively correlated with disease severity; diffusion restriction was inversely correlated with the duration of the disease process. MRS was also a sensitive tool for diagnosing patient of neurologic WD.

    Full Text Available Introduction: Minor blunt head trauma is a common reason for children to present to the emergency department (ED. Crania computed tomography (CT is the choice for evaluating children with blunt head trauma in the ED, but few shows abnormal findings. In this study, we aim to evaluate CT findings in children with blunt head trauma and clinical symptoms to identify clinical predictors of abnormal CT scans. Methods: In this prospective study, 218 children under 2 years of age (121 male and 97 female with mean age of 11.24 ± 4.31 months with compliant of minor blunt head trauma visiting the ED between April 2011 and April 2014 were included. Physical examination and clinical symptoms, as well as CT findings and patients’ outcome were evaluated. Results: Physical examinations were normal in 95.9%, and clinical symptoms were present only in 25.7% including vomiting in 16.1%, loss of consciousness (LOC in 8.3%, ear/nose bleeding in 4.1% and seizure in 5.5%. CT scan was requested in 189 cases (86.7% of which, 7.9% were abnormal including linear fracture in 5.3%, subgaleal hematoma in 1.1% and depressed fracture, subcutaneous hematoma and intracranial hemorrhage (ICH each in 0.5%. Among all cases, 89.0% were discharged from ED with no further observation, 6.0% discharged after 48 h observation and 5.0% were hospitalized. There was a significant correlation between abnormal CT findings and having any clinical symptoms, vomiting and Ear/nose bleeding. Conclusion: In children under 2 years old with minor blunt head trauma, most CT scans are unnecessary. Considering clinical symptoms as predictors of abnormal CT scans we can reduce unnecessary ones.

    Gene therapy is a promising modality for the treatment of inherited and acquired cardiovascular diseases. The identification of the molecular pathways involved in the pathophysiology of heart failure and other associated cardiac diseases led to encouraging preclinical gene therapy studies in small and large animal models. However, the initial clinical results yielded only modest or no improvement in clinical endpoints. The presence of neutralizing antibodies and cellular immune responses directed against the viral vector and/or the gene-modified cells, the insufficient gene expression levels, and the limited gene transduction efficiencies accounted for the overall limited clinical improvements. Nevertheless, further improvements of the gene delivery technology and a better understanding of the underlying biology fostered renewed interest in gene therapy for heart failure. In particular, improved vectors based on emerging cardiotropic serotypes of the adeno-associated viral vector (AAV) are particularly well suited to coax expression of therapeutic genes in the heart. This led to new clinical trials based on the delivery of the sarcoplasmic reticulum Ca(2+)-ATPase protein (SERCA2a). Though the first clinical results were encouraging, a recent Phase IIb trial did not confirm the beneficial clinical outcomes that were initially reported. New approaches based on S100A1 and adenylate cyclase 6 are also being considered for clinical applications. Emerging paradigms based on the use of miRNA regulation or CRISPR/Cas9-based genome engineering open new therapeutic perspectives for treating cardiovascular diseases by gene therapy. Nevertheless, the continuous improvement of cardiac gene delivery is needed to allow the use of safer and more effective vector doses, ultimately bringing gene therapy for heart failure one step closer to reality.

    Ancient non-medical texts can unexpectedly provide useful information on the development of knowledge about the heart and its diseases throughout history. The 750th anniversary of the birth of the Italian poet Dante Alighieri (1265-1321) provides a timely opportunity to analyze medical references in his works, in particular, focusing on literary descriptions that may be attributed to cardiovascular disorders. Dante's high level of medical knowledge, probably derived from his academic studies, is testified by his affiliation to the Florentine Guild of physicians and pharmacists. In all his works, the poet shows a deep interest for the heart. However, his anatomical and physiological knowledge of the circulatory system appears to be poor, probably due to it being based on theories and concepts brought forth by Aristotle and Galen, which were taught in medieval universities. Despite this, accurate descriptions of some symptoms (emotional syncope, orthopnea, dyspnea on exertion) and signs (ascites, paleness), which may be attributed to cardiovascular disorders, can be easily found in Dante's works, particularly in his masterpiece, the Divine Comedy. The literary and historical analysis of cardiovascular signs and symptoms allows us to assume that clinical features due to alterations of heart function were probably known by medieval physicians, but their etiology and pathophysiological mechanisms were not completely understood in that period. Historians of cardiology and clinicians should consider analysis of non-medical texts (including poetry) as an opportunity to better investigate the evolution of their discipline throughout the ages.

    2015-01-01

    Diseases of the heart and vascular system are the leading causes of mortality worldwide. A number of risk factors have already been identified such as obesity, diabetes and smoking; in the recent years, research has shifted its focus on genetic risk factors. Discoveries on the role of genes partnered with the technological developments have enabled advances in the understanding of human genetics and its influence on disease and treatment. There are initiatives now to combine medical records and genetic and other molecular data into a single “knowledge network” to achieve these aptly known as precision medicine. With next generation sequencing readily available at a more affordable cost, it is expected that genetic information of patients will be increasingly available and can be used to guide clinical decisions. Big data generated and stored necessitates broad and extensive interpretation to be valuable in clinical care. Accumulating evidence on the use of such genetic information in the cardiovascular clinics will be presented.

    Objectives To evaluate the values of abnormal heart rate recovery (HRR) after treadmill exercise test in patients with coronary artery disease (CAD). Methods One hundred and seventy-eight consecutive cases of suspected CAD who underwent symptom-limited treadmill exercise test (TET) and coronary angiography (CAG) were enrolled and di-vided into normal and abnormal HRR group based on the status of the values of HRR one or two minutes after TET. The clinical characteristics, TET parameters and CAG results of the two groups were compared attempted to assess the value of HRR on patients with CAD. Results (1) The cases of smoking, diabetes mellitus (DM) and ST segment de-viation at rest in abnormal HRR group were more significantly than those in normal HRR group (all P < 0. 05). (2) The subjects of abnormal HRR usually had higher basal heart rate, more cases exhibited ST segment abnormality and or exercise-limited angina during or after TET(P<0.01 and P<0.05, respectively), but lower level of peak heart rate attained (P<0.05) than those in normal group. The values of metabolism equivalents and duration of TET between the two groups displayed phenomenal difference (P<0.05). There were more samples acquired moderate to high level of Duke test score and chronotropic incompetence in the group of abnormal HRR, compared to the normal HRR group (P<0.01). (3) The cases of negative CAG results in the group of normal and abnormal HRR group were 73 (66.97 % ) and 24 (34.78 %). Cases of significant coronary lesions (at least one major coronary vessel ≥ 50 % stenosis) a-mongst the subgroup of positive CAG were 36 (33.03 % ) and 45 (65.22 %), severe coronary lesions (three-vessel, left main or the equivalents of left main) were 10 (9.17 % ) and 17 (24.64 %) for normal and abnormal HRR respec-tively (P<0.01). Accordingly, the Gensini scores in the subunit of abnormal HRR increased. (4)Linear correlation analysis indicate there was a negative correlation between the values of HRR in

They were investigated by ophthalmic examination, cardiological examination, imaging and laboratory examination. Testing has shown a strong link between cardiovascular disease and the eye of the patients investigated. The study demonstrated the need for interdisciplinary consultation for patients with vascular complaints in the carotid territory and a close correlation between the vascular and ophthalmologic pathology at this level.

    Full Text Available Cardiovascular diseases are the main causes of mortality. Sudden cardiac death may also appear in athletes, due to underlying congenital or inherited cardiac abnormalities. The electrocardiogram is used in clinical practice and clinical trials, as a valid, reliable, accessible, inexpensive method. The aim of the present paper was to review electrocardiographic (ECG signs associated with cardiovascular mortality and the mechanisms underlying those associations, providing a brief description of the main studies in this area, and consider their implication for clinical practice in the general population and athletes. The main ECG parameters associated with cardiovascular mortality in the present paper are the P wave (duration, interatrial block, and deep terminal negativity of the P wave in V1, prolonged QT and Tpeak-Tend intervals, QRS duration and fragmentation, bundle branch block, ST segment depression and elevation, T waves (inverted, T wave axes, spatial angles between QRS and T vectors, premature ventricular contractions, and ECG hypertrophy criteria.

    The cerebral palsy(CP) encephalopathies are often of uncertain etiology and various functional image findings comparing with anatomical image findings have been reported. However, only a few have mentioned its clinical implications. The purpose of our report is to compare clinical severity and functional SPECT abnormalities of thalami and cerebellum in CP patients with normal MRI. Thirty six CP patients with bilateral spastic palsy who had normal MRI and brain SPECT were studied from July 1996 to September 1997. The patients' age at the time of SPECT was 22.84{+-}17.69 months. The patients were divided into two groups according to motor quotient(MQ); moderate defect (>50MQ : n=27 MQ=22.78{+-}10.36), mild defect (<50MQ : n=9, MQ=66.11{+-}13.87). The degree of rCBF decrease between the two groups was evaluated by {chi}{sup 2} test. Brain SPECT was performed following IV administration of 0.05-0.1 mCi/kg (minimum 2.0 mCi) of Tc-99m ECD and chloral hydrate sedation (50-80 mg/kg p.o) using a triple head system (MS 3, Siemens). Interpretation of brain SPECT was visual analysis: severe decrease is defined when the defect is moderate to marked and mild decrease in rCBF as mild. Seven of 36 (19.4%) showed unilateral or bilateral moderate decrease in rCBF in thalami, 20(55.6%) showed mild decrease, and 9(25.0%) showed no decreased rCBF. All 7 who had moderate thalamic defect reveled moderate motor defect clinically. Ten of 36(27.9%) revealed unilateral or bilateral moderate rCBF defect, 23 (63.9%) depicted mild defect, and 3(8.3%) showed no defect. Sixteen with moderate thalamic rCBF defect showed moderate motor defect in 15 patients. There was statistically significant (p=0.02605) relationship between rCBF defect and motor defect in our CP patients. In conclusion, brain SPECT appears sensitive, non-invasive tool in the evaluation as well as in the prognostication of bilateral spastic cerebral palsy patients and deserves further study using larger number of patients.

    BACKGROUND: Myasthenia gravis (MG) is an autoimmune disease which mainly affects neuromuscular junctions. The ages, modified Osserman classification and clinical manifestation and humoral immunol function of MG with and without thymic abnormality are different.OBJECTIVE: To explore the clinical manifestation and humoral immuno-function of MG with abnormal and normal thymus gland.DESIGN: Contrast observation.SETTING: Department of Neurology, the Third Affiliated Hospital of Sun Yat-sen University.PARTICIPANTS: A total of 49 inpatients with MG were selected from the Third Affiliated Hospital of Sun Yat-sen University from March 2000 to August 2005. All the patients had typical clinical manifestation of MG and positive neostigmine test. All the patients knew and agreed the laboratory examinations. There were 22 males and 27 females of 2-69 years old. Chest MRI or CT scan were performed to reveal thymus gland abnormality. According to whether there was tumor in superior mediastinum, all patients were divided into 2 groups, abnormal and normal groups. Normal thymus gland group (n=30) contained 16 males and 14 famales of 6-43 years old. Abnormal thymus gland group (n=19) contained 6 male and 13 female of 2-69years old.METHODS: ① All patients were questioned about initial symptoms. Meanwhile, main clinical manifestations were recorded at hospital admission. ② 7180A automatic biochemical analyzer and automatic microplate reader were used in detecting seroimmunity index. The levels of C3, C4, IgG, IgA, IgM and CH50 in blood serum were analyzed by nephelometry. ③ Clinical classification is based on modified Osserman classification. The patients with MG were divided into six types: Ⅰ (Ocular myasthenia), Ⅱ a (Mild generalized myasthenia), Ⅱ b (Moderately severe generalized myasthenia), Ⅲ (Acute fulminating myasthenia), Ⅳ (Late severe myasthenia).MAIN OUTCOME MEASURES: ① Differences of initial symptoms and clinical manifestation of two group patients.

    Array comparative genomic hybridization (aCGH) testing can diagnose chromosomal microdeletions and duplications too small to be detected by conventional cytogenetic techniques. We need to consider which patients are more likely to receive a diagnosis from aCGH testing versus patients that have lower likelihood and may benefit from broader genome wide scanning. We retrospectively reviewed charts of a population of 200 patients, 117 boys and 83 girls, who underwent aCGH testing in Genetics Clinic at Rhode Island hospital between 1 January/2008 and 31 December 2010. Data collected included sex, age at initial clinical presentation, aCGH result, history of seizures, autism, dysmorphic features, global developmental delay/intellectual disability, hypotonia and failure to thrive. aCGH analysis revealed abnormal results in 34 (17%) and variants of unknown significance in 24 (12%). Patients with three or more clinical diagnoses had a 25.0% incidence of abnormal aCGH findings, while patients with two or fewer clinical diagnoses had a 12.5% incidence of abnormal aCGH findings. Currently, we provide families with a range of 10-30% of a diagnosis with aCGH testing. With increased clinical complexity, patients have an increased probability of having an abnormal aCGH result. With this, we can provide individualized risk estimates for each patient.

    The plasma pool of potassium is a partial reflection of the overall body, transient cellular shifts, and potassium elimination regulated by the kidneys. Potassium concentrations elevating above the upper limit of normal (> 5.0 mEq/L) have become more common in cardiovascular practice due to the growing population of patients with chronic kidney disease and the broad applications of drugs that modulate potassium excretion by either reducing production of angiotensin II (angiotensin-converting enzyme inhibitors, direct renin inhibitors, beta-adrenergic receptor antagonists), blocking angiotensin II receptors (angiotensin receptor blockers), or antagonizing the action of aldosterone on mineralocorticoid receptors (mineralocorticoid receptor antagonists). In addition, acute kidney injury, critical illness, crush injuries, and massive red blood cell transfusions can result in hyperkalemia. Progressively more severe elevations in potassium are responsible for abnormalities in cardiac depolarization and repolarization and contractility. Untreated severe hyperkalemia results in sudden cardiac death. Traditional management steps have included reducing dietary potassium and discontinuing potassium supplements; withdrawal of exacerbating drugs; acute treatment with intravenous calcium gluconate, insulin, and glucose; nebulized albuterol; correction of acidosis with sodium bicarbonate for short-term shifts out of the plasma pool; and, finally, gastrointestinal ion exchange with oral sodium polystyrene sulfonate in sorbitol, which is mainly used in the hospital and is poorly tolerated due to gastrointestinal adverse effects. This review explores hyperkalemia as a complication in cardiovascular patients and highlights new acute, chronic, and preventative oral therapies (patiromer calcium, cross-linked polyelectrolyte, ZS-9) that could potentially create a greater margin of safety for vulnerable patients with combined heart and kidney disease.

    The results of numerous long-term, randomized trials show that statins significantly decrease the risks of myocardial infarction, stroke, and vascular death as well as total mortality. The benefits of statins on cardiovascular disease in patients who are not experiencing acute coronary syndromes generally become apparent only after about 2 years. In contrast, atorvastatin conferred an early clinical benefit in the lipid-lowering arm of the long-term Anglo Scandinavian Cardiac Outcomes Trial as well as early benefit on progression of atherosclerosis in the Reversal of Atherosclerosis with Aggressive Lipid Lowering trial. An unexpected finding at baseline in the prospective Interaction of Atorvastatin and Clopidogrel Study was that patients on atorvastatin had significantly decreased platelet activity compared with either patients on other statins or those taking no statins. Atorvastatin has protective effects against membrane lipid peroxidation at pharmacologic concentrations. These and other considerations contribute to the hypothesis that atorvastatin has pleiotropic effects that translate into early clinical benefits on cardiovascular disease.

    Full Text Available Patients with a low bone mineral density have an increased risk of cardiovascular diseases (CVD and venous thromboembolic events (VTE. The aim of our retrospective chart review was to investigate the prevalence of CVD, VTE, hypertension (HT, and diabetes mellitus type 2 (DM2 in patients with a recent clinical fracture visiting the Fracture Liaison Service (FLS. Out of 3057 patients aged 50–90 years, 1359 consecutive patients, who agreed and were able to visit the FLS for fracture risk evaluation, were included (71.7% women; mean age 65.2 yrs. Based on medical history, 29.9% had a history of CVD (13.7%, VTE (1.7%, HT (14.9%, and DM2 (7.1% or a combination. Their prevalence increased with age (21% in patients aged 50–59 years to 48% in patients aged >80 years and was higher in men than in women (36% versus 27%, but independent of bone mineral density and fracture type. Careful evaluation of medical history with respect to these risk factors should be performed in patients with a recent clinical fracture before starting treatment with medications that increase the risk of VTE or cardiovascular events, such as raloxifene, strontium ranelate, or NSAIDs.

    Infection is one of the most devastating outcomes of cardiovascular implantable electronic device (CIED) implantation and is related to significant morbidity and mortality. In our country, there is no evaluation about CIED infection. Therefore, our aim was to investigate clinical characteristics and outcome of patients who had infection related to CIED implantation or replacement. The study included 144 consecutive patients with CIED infection treated at 11 major hospitals in Turkey from 2005 to 2014 retrospectively. We analyzed the medical files of all patients hospitalized with the diagnosis of CIED infection. Inclusion criteria were definite infection related to CIED implantation, replacement, or revision. Generator pocket infection, with or without bacteremia, was the most common clinical presentation, followed by CIED-related endocarditis. Coagulase-negative staphylococci and Staphylococcus aureus were the leading causative agents of CIED infection. Multivariate analysis showed that infective endocarditis and ejection fraction were the strongest predictors of in-hospital mortality.

    We reviewed available evidence for cardiovascular effects of n-3 polyunsaturated fatty acid (PUFA) consumption, focusing on long chain (seafood) n-3 PUFA, including their principal dietary sources, effects on physiological risk factors, potential molecular pathways and bioactive metabolites, effects on specific clinical endpoints, and existing dietary guidelines. Major dietary sources include fatty fish and other seafood. n-3 PUFA consumption lowers plasma triglycerides, resting heart rate, and blood pressure and might also improve myocardial filling and efficiency, lower inflammation, and improve vascular function. Experimental studies demonstrate direct anti-arrhythmic effects, which have been challenging to document in humans. n-3 PUFA affect a myriad of molecular pathways, including alteration of physical and chemical properties of cellular membranes, direct interaction with and modulation of membrane channels and proteins, regulation of gene expression via nuclear receptors and transcription factors, changes in eicosanoid profiles, and conversion of n-3 PUFA to bioactive metabolites. In prospective observational studies and adequately powered randomized clinical trials, benefits of n-3 PUFA seem most consistent for coronary heart disease mortality and sudden cardiac death. Potential effects on other cardiovascular outcomes are less-well-established, including conflicting evidence from observational studies and/or randomized trials for effects on nonfatal myocardial infarction, ischemic stroke, atrial fibrillation, recurrent ventricular arrhythmias, and heart failure. Research gaps include the relative importance of different physiological and molecular mechanisms, precise dose-responses of physiological and clinical effects, whether fish oil provides all the benefits of fish consumption, and clinical effects of plant-derived n-3 PUFA. Overall, current data provide strong concordant evidence that n-3 PUFA are bioactive compounds that reduce risk of cardiac

    Integrating clinical research data entry with patient care data entry is a challenging issue. At the G. Pompidou European Hospital (HEGP), cardiovascular radiology reports are captured twice, first in the Electronic Health Record (EHR) and then in a national clinical research server. Informatics standards are different for EHR (HL7 CDA) and clinical research (CDISC ODM). The objective of this work is to feed both the EHR and a Clinical Research Data Management System (CDMS) from a single multipurpose form. We adopted and compared two approaches. First approach consists in implementing the single "care-research" form within the EHR and aligning XML structures of HL7 CDA document and CDISC ODM message to export relevant data from EHR to CDMS. Second approach consists in displaying a single "care-research" XForms form within the EHR and generating both HL7 CDA document and CDISC message to feed both EHR and CDMS. The solution based on XForms avoids overloading both EHR and CDMS with irrelevant information. Beyond syntactic interoperability, a perspective is to address the issue of semantic interoperability between both domains.

    Full Text Available Cardiovascular diseases (CVD remain the major cause of death and premature disability in Western societies. Assessing the risk of CVD is an important aspect in clinical decision-making. Among the growing number of molecules that are studied for their potential utility as CVD biomarkers, a lot of attention has been focused on osteoprotegerin (OPG and its ligands, which are receptor activator of nuclear factor κB ligand (RANKL and TNF-related apoptosis-inducing ligand. Based on the existing literature and on our experience in this field, here we review what the possible roles of OPG and TRAIL in CVD are and their potential utility as CVD biomarkers.

    2007-01-01

    Active control noninferiority trials are being used with increasing frequency in new drug or device development when standard placebo-controlled trials are considered unethical. Nevertheless, the design and analysis of these trials are founded on a number of assumptions and arbitrary criteria that are generally not well understood or justifiable. Trials designed to show noninferiority require an appropriate reference population, a proven active control and dose, an appropriate margin of noninferiority that is clinically relevant and statistically justifiable, a high level of adherence to treatment, and adequate statistical power to reliably conclude that a treatment is truly noninferior and therefore effective. Accordingly, if noninferiority trials are to be applied to clinical and regulatory decisions regarding the marketing and use of new treatments, the assumptions must be made explicit and their influence on the resultant conclusions must be assessed rigorously. When conservative criteria were applied to each of the key assumptions underlying 2 representative noninferiority trials, they materially undermined the conclusions regarding noninferiority failing to confirm reported conclusions regarding noninferiority despite enthusiastic dissemination and acceptance of the results. Because the clinical, regulatory, and economic impact of active control noninferiority trials is substantial, robust criteria should be used routinely in their design, analysis, and interpretation to reach their intended objectives and to keep them from becoming wasted efforts.

    Full Text Available INTRODUCTION: Periodontal disease is an inflammatory response to bacteria that reside in the gum tissue and can have systemic repercussion. OBJECTIVE: The aim of this study was to assess the relationship between periodontitis and markers of cardiovascular risk. MATERIAL AND METHOD: Ninety selected patients were assigned into two groups in accordance with their levels of probing pocket depth (PPD and Clinical Attachment Level (CAL: control group, n= 45 (< 4 sites with PPD ≥ 4.0 mm and CAL ≥ 3.0 mm and case group, n= 45 (≥ 30% of sites with PPD ≥ 4.0 mm and CAL ≥3.0 mm. Plasma concentrations of C-reactive protein, high sensitive CRP, high-density lipoproteins (HDL-c and electronegative low density lipoproteins (LDL were assessed in all participants. Data from medical history and socioeconomic level were also collected from patients. RESULT: Plasma levels of HDL-c were lower in subjects with periodontal disease (p = 0.016 and were inversely associated with the number of sites with PPD ≥ 3 mm (rho= -0.325 and number of sites with PPD ≥ 3 mm and CAL ≥ 3 mm (rho= -0.216. These associations remained significant after adjustments for dental plaque and smoking using Univariate Analysis of Covariance (p < 0.05. Adjusted odds ratio between periodontal disease and levels of HDL-c was 0.94 (CI95% 0.88-0.99 after adjusting for age, smoking and dental plaque. Other investigated markers of cardiovascular risk were not related to periodontal disease. CONCLUSION: Clinical parameters of periodontitis were inversely associated with plasma concentrations of HDL-c.

    Diabetes is a major risk factor for cardiovascular disease, and recent advances in research indicate that a detailed understanding of the pathophysiology of its effects is mandatory to reduce diabetes-related mortality and morbidity. Advanced Glycation End Products (AGEs) play a central role in the genesis and progression of complications of both type 1 and type 2 diabetes mellitus, and have been found to be important even in non-diabetic patients as a marker of cardiovascular disease. AGEs have a profound impact on patient's prognosis regardless of the glycemic control, and therefore pharmacologic approaches against AGEs accumulation have been proposed over the years to treat cardiovascular diseases, parallel to a more detailed understanding of AGEs pathophysiology. Compounds with anti-AGEs effects are currently under investigation in both pre-clinical and clinical scenarios, and many of the drugs previously used to treat specific diseases have been found to have AGE-inhibitory effects. Some products are still in "bench evaluation", whereas others have been already investigated in clinical trials with conflicting evidences. This review aims at summarizing the mechanisms of AGEs formation and accumulation, and the most relevant issues in pre-clinical and clinical experiences in anti-AGEs treatment in cardiovascular research.

    2011-11-03

    This paper presents a summary of the potential practical and economic barriers to implementation of primary prevention of cardiovascular disease guided by total cardiovascular risk estimations in the general population. It also reviews various possible solutions to overcome these barriers. The report is based on discussion among experts in the area at a special CardioVascular Clinical Trialists workshop organized by the European Society of Cardiology Working Group on Cardiovascular Pharmacology and Drug Therapy that took place in September 2009. It includes a review of the evidence in favour of the \\'treat-to-target\\' paradigm, as well as potential difficulties with this approach, including the multiple pathological processes present in high-risk patients that may not be adequately addressed by this strategy. The risk-guided therapy approach requires careful definitions of cardiovascular risk and consideration of clinical endpoints as well as the differences between trial and \\'real-world\\' populations. Cost-effectiveness presents another issue in scenarios of finite healthcare resources, as does the difficulty of documenting guideline uptake and effectiveness in the primary care setting, where early modification of risk factors may be more beneficial than later attempts to manage established disease. The key to guideline implementation is to improve the quality of risk assessment and demonstrate the association between risk factors, intervention, and reduced event rates. In the future, this may be made possible by means of automated data entry and various other measures. In conclusion, opportunities exist to increase guideline implementation in the primary care setting, with potential benefits for both the general population and healthcare resources.

  18. A Mobile Clinical Decision Support Tool for Pediatric Cardiovascular Risk-Reduction Clinical Practice Guidelines: Development and Description

    2017-01-01

    Background Widespread application of research findings to improve patient outcomes remains inadequate, and failure to routinely translate research findings into daily clinical practice is a major barrier for the implementation of any evidence-based guideline. Strategies to increase guideline uptake in primary care pediatric practices and to facilitate adherence to recommendations are required. Objective Our objective was to operationalize the US National Heart, Lung, and Blood Institute’s Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents into a mobile clinical decision support (CDS) system for healthcare providers, and to describe the process development and outcomes. Methods To overcome the difficulty of translating clinical practice guidelines into a computable form that can be used by a CDS system, we used a multilayer framework to convert the evidence synthesis into executable knowledge. We used an iterative process of design, testing, and revision through each step in the translation of the guidelines for use in a CDS tool to support the development of 4 validated modules: an integrated risk assessment; a blood pressure calculator; a body mass index calculator; and a lipid management instrument. Results The iterative revision process identified several opportunities to improve the CDS tool. Operationalizing the integrated guideline identified numerous areas in which the guideline was vague or incorrect and required more explicit operationalization. Iterative revisions led to workable solutions to problems and understanding of the limitations of the tool. Conclusions The process and experiences described provide a model for other mobile CDS systems that translate written clinical practice guidelines into actionable, real-time clinical recommendations.

    Cardiovascular disease remains the principal cause of death and disability among patients with diabetes mellitus. Diabetes mellitus exacerbates mechanisms underlying atherosclerosis and heart failure. Unfortunately, these mechanisms are not adequately modulated by therapeutic strategies focusing solely on optimal glycemic control with currently available drugs or approaches. In the setting of multifactorial risk reduction with statins and other lipid-lowering agents, antihypertensive therapies, and antihyperglycemic treatment strategies, cardiovascular complication rates are falling, yet remain higher for patients with diabetes mellitus than for those without. This review considers the mechanisms, history, controversies, new pharmacological agents, and recent evidence for current guidelines for cardiovascular management in the patient with diabetes mellitus to support evidence-based care in the patient with diabetes mellitus and heart disease outside of the acute care setting.

    2014-01-01

    The U.S. Food and Drug Administration (FDA) periodically publishes Drug Safety Communications and Drug Alerts notifying health care practitioners and the general public of important information regarding drug therapies following FDA approval. These alerts can result in both positive and negative effects on patient care. Most clinical trials are not designed to detect long-term safety end points, and postmarketing surveillance along with patient reported events are often instrumental in signaling the potential harmful effect of a drug. Recently, many cardiovascular (CV) safety announcements have been released for FDA-approved drugs. Because a premature warning could discourage a much needed treatment or prompt a sudden discontinuation, it is essential to evaluate the evidence supporting these FDA alerts to provide effective patient care and to avoid unwarranted changes in therapy. Conversely, paying attention to these warnings in cases involving high-risk patients can prevent adverse effects and litigation. This article reviews the evidence behind recent FDA alerts for drugs with adverse CV effects and discusses the clinical practice implications.

A total of 2,540 patients (68.1 years; 60.7% male; 8.4% smokers, 52.9% ex-smokers, and 38.7% never smokers) fulfilling the selection criteria and followed up throughout a period of 36 months after the event were considered eligible for analysis. Total costs were higher among current smokers in comparison with ex-smokers and never smokers (€7,981 versus [vs] €7,322 and €5,619, respectively) (P < 0.001). Both health care costs (€6,273 vs €5,673 and €4,823, respectively) (P < 001) and loss of productivity at work costs (€1,708 vs €1,650 and €796, respectively) (P < 001) accounted for such differences. There was also a difference in CVE recurrence rates (18.6% vs 16.5% and 9.6%, respectively) (P < 01). Smoking cessation in CVE outpatients was associated with lower cost and risk of CVE recurrence compared with smokers, and their health status was similar to that of never smokers, in routine clinical practice in Spain.

    Karyotypic abnormalities were detected in the malignant cells of 6 of 18 patients with multiple myeloma (MM). Six patients with benign monoclonal gammopathy, one with amyloidosis of immunoglobulin origin, and two with Waldenstroem's macroglobulinemia had normal karyotypes. All six MM patients with aneuploidy were in a group of 10 patients in an accelerated or relapse phase of their disease and four had high serum paraprotein levels when their abnormal karyotypes were detected. Five of the 6 MM patients with aneuploidy had received prior chemotherapy. Aneuploidy was not observed in 8 stable MM patients. Abnormalities of chromosome 14 were present in all 6 patients. A translocation between Nos. 11 and 14 was found in aneuploid cells of 2 patients who had plasma cell leukemia (PCL). A deletion of chromosome 6 was detected in 2 MM patients and a pericentric inversion of No. 6 was seen in the patient with PCL. Three of 4 MM patients had a nonrandom loss of one chromosome 8. Two other MM patients developed acute nonlymphocytic leukemia (ANLL) after the diagnosis of MM. Marrow cells of one patient showed a 5q- chromosome and a constitutional translocation involving Nos. 13 and 14 during the preleukemic stage; during the leukemic phase, the karyotype evolved to 50 chromosomes including extra chromosomes 1, 6, 8, 10, and 21 and a missing 7, in addition to the originally detected 5q- and the 13/14 translocation.The peripheral blood from the other patient was hypodiploid, with a missing chromosome 7 and a translocation between 3q and 9p. These patterns of chromosome change resemble those of ANLL rather than MM and are similar to the changes seen in ANLL after treated malignant lymphoma.

    Thirty-four patients with bone tumours and tumour-like abnormalities of the skeleton, of varying ages, were examined by a computer-aided diagnostic programm; the accuracy, clinical usefullness and specific advantages and disadvantages of the programm have been evaluated. This was done by two statistical methods, both with showed high accuracy and reliability of the system (97% and 88,2%). In addition to the diagnostic results, the growth rate of the lesion could be estimated. This indicates the biological behaviour of the tumour independently of the histological diagnosis.

    .BACKGROUND: Berardinelli-Seip syndrome (BSS or Generalized Congenital Lipodystrophy often affects the cardiovascular system and also promotes metabolic abnormalities involving glycidic and lipid metabolisms. OBJECTIVE: To assess the prevalence of cardiometabolic abnormalities in patients with BSS. METHODS: Twenty-two patients from the state of Rio Grande do Norte, Brazil, diagnosed with BSS, underwent clinical evaluation, resting electrocardiogram, echodopplercardiogram, chest X-ray, 24-hour ambulatory electrocardiogram monitoring, exercise testing and laboratory analysis. RESULTS: The patients were predominantly young adults, most of whom women. The whole sample showed insulin resistance, acanthosis nigricans and diminished HDL-cholesterol. The presence of splenomegaly, hepatomegaly, type II diabetes and elevated triglycerides was constant. Metabolic syndrome was characterized in most patients, which were predominantly women and with a high degree of paternal consanguinity. SAH and prehypertension blood pressure were found in more than half of the patients (77.3%. The echodopplercardiogram showed the presence of CLVH (50%, eccentric left ventricular hypertrophy (4.5%, and normal left ventricular geometry (45.5%. High arrhythmia rates were observed by Holter monitoring, such as ventricular ectopic beats, supraventricular ectopic beats and sustained supraventricular tachycardia. Chronotropic incompetence (54.5% was observed during exercise testing. CONCLUSION: A high prevalence of cardiovascular and metabolic abnormalities was observed in young asymptomatic individuals with BSS. These findings point to the need for systematic cardiological follow-up and of preventive measures in this high-risk group.

    Autism spectrum disorders (ASD) are neurodevelopment disorders that cause severe and pervasive impairment in socialization, communication, and behavior. Although the availability of antipsychotic treatment in ASD has expanded, we will be very careful with side effects of these pharmacological agents. Following this reasoning, emerging data indicate that some antipsychotics may be associated with cardiovascular adverse events (e.g., QT interval prolongation), suggesting that this could be correlated to sudden death. Quite interesting, substantial evidence from epidemiological and case-control studies indicates that omega-3 reduces the risk of cardiovascular mortality, particularly sudden cardiac death. In accordance to the above mentioned findings, as omega-3 fatty acids per se have a direct cardiovascular protective role, our paper hypothesized that omega-3 fatty acids supplementation in ASD patients treated with atypical antipsychotic drugs may reduce cardiac arrhythmias and hence sudden cardiac death.

    Electroencephalographic (EEG) abnormalities have been reported during migraine attacks but their spatial and temporal distributions are not well known. We report the temporospatial dynamics of EEG during the full duration of a migraine attack with aura in a 19-year-old woman. She experienced episodes of hemiplegic migraine since the age of 2.5 years, with right hemibody paralysis preceded by visual symptoms. She reported severe pain of the right hemibody just before hemiplegia that was enventually suggestive of possible epileptic seizure, justifying diagnostic video-EEG monitoring. Sporadic hemiplegic migraine was diagnosed in the absence of family history. EEG was normal at the beginning of visual aura. After 15minutes, posterior slow waves appeared over the migrainous hemisphere, spreading progressively towards anterior regions: first the central region (5minutes after onset of contralateral hemiplegia), then the frontal region and over both hemispheres. A new de novo mutation was identified in the SCN1A gene.

    Full Text Available Exercise testing is associated with barriers prevent using cardiovascular (CV endurance (CVE measure frequently. A recent nonexercise model (NM is alleged to estimate CVE without exercise. This study examined CVE relationships, using the NM model, with measures of obesity, physical fitness (PF, blood glucose and lipid, and circulation in 188 asymptomatic young (18–40 years adults. Estimated CVE correlated favorably with measures of PF (r=0.4-0.5 including handgrip strength, distance in 6 munities walking test, and shoulder press, and leg extension strengths, obesity (r=0.2-0.7 including % body fat, body water content, fat mass, muscle mass, BMI, waist and hip circumferences and waist/hip ratio, and circulation (r=0.2-0.3 including blood pressures, blood flow, vascular resistance, and blood (r=0.2-0.5 profile including glucose, total cholesterol, LDL-C, HDL-C, and triglycerides. Additionally, differences (P<0.05 in examined measures were found between the high, average, and low estimated CVE groups. Obviously the majority of these measures are CV disease risk factors and metabolic syndrome components. These results enhance the NM scientific value, and thus, can be further used in clinical and nonclinical settings.

  17. Evidence supporting primary prevention of cardiovascular diseases with statins: Gaps between updated clinical results and actual practice.

    2014-03-01

    The use of pharmacological lipid-lowering intervention in individuals with hypercholesterolaemia and known cardiovascular disease or diabetes/chronic kidney disease is well established. Current European Society of Cardiology guidelines recommend immediate initiation of drugs in adjunct to lifestyle intervention in these patients at high or very high cardiovascular risk. In these clinical settings, statins are generally chosen as the first-choice drug intervention, in consideration of the robust evidence showing a reduction in all-cause mortality and major adverse cardiac events (MACE). In contrast, primary prevention with statins, even in the subset of patients at high-risk of cardiovascular events, is not well implemented. This might be related to a lack of public awareness regarding the actual risk associated with prolonged exposure to high concentrations of low-density lipoprotein cholesterol (LDL-C) and uncertainties in the clinical evidence coming from the earliest trials in this patient subset. However, recent observational studies suggest that lowering LDL-C earlier in life and for a longer duration can substantially decrease the burden of cardiovascular disease and mortality. Moreover, results from recent well-conducted large meta-analyses of randomized clinical trials showed that primary prevention with statins reduced all-cause mortality by 14% and MACE by > 20% - findings similar to those observed for the use of statins in secondary prevention. Recently published American Heart Association/American College of Cardiology guidelines on the treatment of blood cholesterol emphasize that primary prevention using high-dose statins in individuals with LDL-C ≥ 190 mg/dL induces a benefit in atherosclerotic cardiovascular risk reduction that clearly exceeds the potential for adverse effects. We aim in this review to discuss the new data that advocate the use of statins in primary prevention earlier and more frequently, putting the efficacy evidence into

    Little evidence exists examining cardiovascular risk factors among Asian Americans and how social determinants such as nativity status and education pattern risk in the United States (U.S.) context. We used the 2011-2014 National Health and Nutrition Examination Survey, which purposely oversampled Asian Americans from 2011 to 2014, and examined prevalence of Type II diabetes, smoking and obesity for Asian Americans (n=1363) and non-Latino Whites (n=4121). We classified Asian Americans as U.S. or foreign-born and by years in the U.S. Obesity status was based on standard body mass index (BMI) cut points of ≥30kg/m(2) and Asian-specific cut points (BMI≥25kg/m(2)) that may be more clinically relevant for this population. We fit separate logistic regression models for each outcome using complex survey design methods and tested for the joint effect of race, nativity and education on each outcome.Diabetes and obesity prevalence (applying Asian-specific BMI cut points) were higher among Asian Americans when compared to non-Latino Whites but smoking prevalence was lower. These patterns remained in fully adjusted models and showed small increases with longer duration in the U.S. Joint effects models showed higher odds of prevalent Type II diabetes and obesity (Asian-specific) for foreign-born Asians, regardless of years in the U.S. and education, when compared to non-Latino Whites with high education. Smoking models showed significant interaction effects between race and education for non-Latino Whites only. Our study supports the premise that social as well as clinical factors should be considered when developing health initiatives for Asian Americans.

    Genomics-based non-invasive prenatal screening using cell-free DNA (cfDNA screening) was proposed to reduce the number of invasive procedures in current prenatal diagnosis for fetal aneuploidies. We review here the clinical and ethical issues of cfDNA screening. To date, it is not clear how cfDNA screening is going to impact the performances of clinical prenatal diagnosis and how it could be incorporated in real life. The direct marketing to users may have facilitated the early introduction of cfDNA screening into clinical practice despite limited evidence-based independent research data supporting this rapid shift. There is a need to address the most important ethical, legal, and social issues before its implementation in a mass setting. Its introduction might worsen current tendencies to neglect the reproductive autonomy of pregnant women.

  1. Simulating the impact of improved cardiovascular risk interventions on clinical and economic outcomes in Russia.

    Full Text Available OBJECTIVES: Russia faces a high burden of cardiovascular disease. Prevalence of all cardiovascular risk factors, especially hypertension, is high. Elevated blood pressure is generally poorly controlled and medication usage is suboptimal. With a disease-model simulation, we forecast how various treatment programs aimed at increasing blood pressure control would affect cardiovascular outcomes. In addition, we investigated what additional benefit adding lipid control and smoking cessation to blood pressure control would generate in terms of reduced cardiovascular events. Finally, we estimated the direct health care costs saved by treating fewer cardiovascular events. METHODS: The Archimedes Model, a detailed computer model of human physiology, disease progression, and health care delivery was adapted to the Russian setting. Intervention scenarios of achieving systolic blood pressure control rates (defined as systolic blood pressure <140 mmHg of 40% and 60% were simulated by modifying adherence rates of an antihypertensive medication combination and compared with current care (23.9% blood pressure control rate. Outcomes of major adverse cardiovascular events; cerebrovascular event (stroke, myocardial infarction, and cardiovascular death over a 10-year time horizon were reported. Direct health care costs of strokes and myocardial infarctions were derived from official Russian statistics and tariff lists. RESULTS: To achieve systolic blood pressure control rates of 40% and 60%, adherence rates to the antihypertensive treatment program were 29.4% and 65.9%. Cardiovascular death relative risk reductions were 13.2%, and 29.6%, respectively. For the current estimated 43,855,000-person Russian hypertensive population, each control-rate scenario resulted in an absolute reduction of 1.0 million and 2.4 million cardiovascular deaths, and a reduction of 1.2 million and 2.7 million stroke/myocardial infarction diagnoses, respectively.

    2015-01-01

    Full Text Available Background: Computed tomography (CT used in pediatric pediatrics brain injury (TBI to ascertain neurological manifestations. Nevertheless, this practice is associated with adverse effects. Reports in the literature suggest incidents of morbidity and mortality in children due to exposure to radiation. Hence, it is found imperative to search for a reliable alternative. Objectives: The aim of this study is to find a reliable clinical alternative to detect an intracranial injury without resorting to the CT. Materials and Methods: Retrospective cross-sectional study was undertaken in patients (1-14 years with blunt head injury and having a Glasgow Coma Scale (GCS of 13-15 who had CT performed on them. Using statistical analysis, the correlation between clinical examination and positive CT manifestation is analyzed for different age-groups and various mechanisms of injury. Results: No statistically significant association between parameteres such as Loss of Consciousness, ′fall′ as mechanism of injury, motor vehicle accidents (MVA, more than two discrete episodes of vomiting and the CT finding of intracranial injury could be noted. Analyzed data have led to believe that GCS of 13 at presentation is the only important clinical predictor of intracranial injury. Conclusion: Retrospective data, small sample size and limited number of factors for assessing clinical manifestation might present constraints on the predictive rule that was derived from this review. Such limitations notwithstanding, the decision to determine which patients should undergo neuroimaging is encouraged to be based on clinical judgments. Further analysis with higher sample sizes may be required to authenticate and validate findings.

    Castro, Hector; Raij, Leopoldo

    2013-05-01

    The increased prevalence of hypertension and cardiovascular disease in industrialized societies undoubtedly is associated with the modern high-sodium/low-potassium diet. Extensive experimental and clinical data strongly link potassium intake to cardiovascular outcome. Most studies suggest that the sodium-to-potassium intake ratio is a better predictor of cardiovascular outcome than either nutrient individually. A high-sodium/low-potassium environment results in significant abnormalities in central hemodynamics, leading to potential target organ damage. Altered renal sodium handling, impaired endothelium-dependent vasodilatation, and increased oxidative stress are important mediators of this effect. It remains of paramount importance to reinforce consumption of a low-sodium/high-potassium diet as a critical strategy for prevention and treatment of hypertension and cardiovascular disease.

An interviewer-administered questionnaire was used to obtain data on self-reported CVD (coronary heart disease [CHD], cerebrovascular disease, and peripheral vascular disease [PVD], physical activity, alcohol consumption, and smoking. Trained nurses performed blood pressure and anthropometric measurements. A capillary blood sample was collected to measure glycosylated hemoglobin, and urine was tested for protein and microalbumin. Means and proportions for patient characteristics, CVD outcomes, and risk factors were calculated. Logistic regression was used to identify factors independently associated with CVD.Results: Data from 129 women and 45 men (mean age 55.7 ± 14.7 years were analyzed. The prevalence of any self-reported CVD (CHD, cerebrovascular disease, or PVD was 34.5% (95% confidence interval [CI] 27.4–41.6. PVD had the highest prevalence (25.9%, compared with CHD (6.9% and cerebrovascular disease (16.1%. There were no gender differences in the prevalence of CVD. Prevalence of CVD was higher among people ≥50 years, and those with high blood pressure, central obesity, high total cholesterol, and duration of diabetes ≥20 years.

    2007-06-01

    Full Text Available Abstract A 12-year-old girl presented with a 4 year history of an enlarged, firm thyroid gland. On exam, her thyroid was firm and fixed and an enlarged cervical lymph node was palpable as well. Though a thyroid ultrasound prior to referral was read as thyroiditis, clinical suspicion for thyroid carcinoma mandated continued investigation. The diagnosis of papillary thyroid cancer was established and her workup revealed lymph node metastases as well as a tremendous burden of pulmonary metastases. Pediatric thyroid cancer is extremely rare, but often presents with aggressive disease. Palpable thyroid abnormalities in an individual under 20-years-old should be viewed with suspicion and should be thoroughly investigated to rule out malignancy even in the face of negative diagnostic procedures. Though pediatric papillary thyroid cancer often presents with loco-regional and even distant metastatic disease, mortality rates in follow-up for as long as 20 years are very favorable.

We review here the clinical and ethical issues of cfDNA screening. To date, it is not clear how cfDNA screening is going to impact the performances of clinical prenatal diagnosis and how it could be incorporated in real life. The direct marketing to users may have facilitated the early introduction of cfDNA screening into clinical practice despite limited evidence-based independent research data supporting this rapid shift. There is a need to address the most important ethical, legal, and social issues before its implementation in a mass setting. Its introduction might worsen current tendencies to neglect the reproductive autonomy of pregnant women.

    Full Text Available BACKGROUND: Therapeutic intervention with low-density lipoprotein cholesterol-lowering agents known as statins has been demonstrated to reduce cardiovascular risk. However, many patients on statin treatment have persistent dyslipidemia and remain at a high risk of cardiovascular disease. Therefore, the objective of this study was to assess the frequency of lipid abnormalities in patients receiving chronic statin treatment. METHODS: As part of an international, cross-sectional, observational study, DYSIS-Middle East enrolled 2,182 patients in the United Arab Emirates (UAE, Saudi Arabia, Lebanon and Jordan. All patients were over 45 years of age and had been on statin treatment for at least three months. Data on demographics, lipid parameters and cardiovascular risk profile were recorded. Cardiovascular risk was defined according the guidelines of the European Society of Cardiology. RESULTS: The majority of patients (82.6% were classified as being at very high risk of cardiovascular events, and 61.8% of all patients did not attain LDL-C target levels. Low high-density lipoprotein cholesterol levels and elevated triglyceride levels were noted in 55.5% and 48.5% of patients, respectively. Multivariate logistical regression modeling indicated that factors independently associated with LDL-C levels not being at goal were lifestyle choices, diabetes mellitus, ischemic heart disease, and blood pressure ≥ 140/90 mmHg. CONCLUSIONS: Almost two-thirds of statin-treated patients in the United Arab Emirates, Saudi Arabia, Lebanon and Jordan had inadequately controlled lipid levels. More comprehensive surveillance, awareness and treatment regimens, as well as modification of lifestyle choices, is necessary to halt the rise in cardiovascular disease-related mortality.

    The findings of a previous chest X-ray screening, determined without using standardized criteria, were reassessed by means of the ILO classification. Of 470 radiographs that had been determined as showing asbestos-related changes, 430 were categorized according to the ILO Classification. Small opacities with profusion greater than or equal to 1/0 were described in 39 (52%) of 75 participants who, on the original clinical reading, had been determined as having lung fibrosis, and in 45 (12.7%) of 355 who were determined as having pleural changes only. When considering circumscribed pleural thickening at the chest wall or diaphragm, as categorized by the ILO Classification, such changes were present in 401 (93.7%) of 428 subjects with pleural changes as determined on the clinical reading. In addition to the improved sensitivity and specificity achieved, the ILO Classification also allows comparison with other studies. The most apparent disadvantage of the ILO system is that it cannot firmly separate the various types of asbestos-related pleural changes. The study revealed that the previous asbestos exposure of the case subjects had occurred in many different workplaces and occupations.

    Renal vein thrombosis (RVT) in neonates is a rare condition of low mortality but significant morbidity due to renal impairment.We report the case of a male term newborn with left RVT and elevated serum factor VIII (FVIII).The main symptoms of the patient and the important clinical findings: prompt diagnosis of RVT was possible because the classic clinical presentation of macroscopic hematuria, thrombocytopenia, and palpable flank mass were present in this newborn infant.The main diagnoses: finally, the reason of RVT was established when the infant was 3 months of age: the increased level of FVIII was confirmed. We discuss the diagnosis, therapy, and outcome of the patient and compare with the literature.Therapeutics interventions: however, despite anticoagulant therapy the left kidney developed areas of scarring and then atrophy.Conclusions and outcomes: Prothrombotic defects should be considered in all patients with perinatal RVT. Elevated factor VIII as a reason of RVT in neonatal period is particularly rare. Given a poor renal outcome in children associated with elevated levels of factor VIII, consideration could be given to more aggressive antithrombotic therapy in such cases.

    Background A clinical medication review, including patient involvement, is expected to improve pharmaceutical care. Objective To determine whether a clinical medication review followed by a pharmaceutical care plan decreases the number of potential drug-related problems (DRPs) and pharmaceutical care issues (PCIs) and leads to a positive effect on relevant clinical and laboratory parameters for elderly cardiovascular patients with multiple drug use. Setting Randomized controlled trial in eight primary care settings in the Netherlands. Method Elderly polypharmacy patients with a cardiovascular disorder were randomized into two groups. Intervention patients received a clinical medication review, followed by a pharmaceutical care plan developed in cooperation between these patients' pharmacists and general practitioners (GPs), and agreed to by the patients. Control patients received care as usual. Patient data were collected at the start of the study (t = 0) and after 1-year follow-up (t = 1). Main outcome measure Decrease in potential DRPs and pharmaceutical PCIs, improvement of clinical and laboratory parameters. Results 512 patients were included. An average of 2.2 potential DRPs and pharmaceutical PCIs were defined per patient in the intervention group. After 1-year follow-up, 47.2 % of potential DRPs and PCIs were resolved. In total, 156 care interventions were proposed (0.9/patient), 108 of which were implemented after 1 year (69.2 %). For control-group patients, a total of 47 proposed care interventions were documented for 255 patients (0.2/patient); after 1 year, 43 had been implemented (91.5 %). The study intervention (p pharmaceutical care plan in a primary care setting supports the detection of and decrease in DRPs and pharmaceutical PCIs in almost half of the patients. Its benefit in terms of control of cardiovascular risk factors and safety parameters was relatively low. Risk stratification might be necessary to decide which patients might benefit

    We conducted a survey of the National Centre for Biotechnology Information (NCBI) PubMed database to identify methods most commonly used for the evaluation of the effect of plant food supplements on the cardiovascular system and their relevance to the regulatory status of these products. Particularly, our search strategy was aimed at the selection of studies concerning the clinical evaluation of the beneficial effects of the most commonly studied plant food supplements acting on the cardiovascular system. Following the screening of 3839 papers for inclusion criteria, 48 published reports were retained for this review. Most studies included in this review used a double blind controlled design, and evaluated the effect of plant food supplements on individuals affected by a disease of the cardiovascular system. The majority of the studies were found to be of low methodological quality on the Jadad scale, mainly because of inadequate reporting of adverse events and of patient withdrawals. In comparison, measures used for the evaluation of benefits included mostly cardiovascular risk factors as recommended in international guidelines and in accordance with principles laid down for the evaluation of health claims in food. The risk factors most frequently evaluated belonged to the category of "lipid function and levels", "heart function" and "blood pressure". For the absolute majority of the studies, the study period did not exceed one month. This review highlights critical factors to be considered in the design of studies evaluating the health effects of plant food supplements on the cardiovascular system. Between others, the inclusion of healthy individuals, better reporting and description of the characteristics of the product used could improve the quality and relevance of these studies.

  1. Review of the evidence for the clinical utility of lipoprotein-associated phospholipase A2 as a cardiovascular risk marker.

    A substantial body of peer-reviewed studies has been published validating the role of inflammation in atherogenesis and supporting lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) as a cardiovascular risk marker independent of and additive to traditional risk factors. As with elevated high-sensitivity C-reactive protein, an elevated Lp-PLA(2) level approximately doubles the risk for primary and secondary cardiovascular events. Interestingly, when both inflammatory markers are increased together, they provide an even greater predictive capability to help identify very-high-risk individuals who would benefit most from aggressive lipid-lowering therapy. High levels of Lp-PLA(2) are present in inflamed, rupture-prone plaques, and it appears that Lp-PLA(2) is released from these plaques into the circulation. Over 25 prospective epidemiologic studies have demonstrated the association of elevated Lp-PLA(2) levels with future coronary events and stroke-11 of 12 prospective studies have shown a statistically significant association between elevated Lp-PLA(2) and primary coronary or cardiovascular events, 12 of 13 have shown a statistically significant association with recurrent coronary or cardiovascular events, and 6 studies have shown a positive association with stroke. Lp-PLA(2) should be viewed today as an important cardiovascular risk marker whose utility is as an adjunct to the major risk factors to adjust absolute risk status and thereby modify low-density lipoprotein cholesterol goals. The low biologic fluctuation and high vascular specificity of Lp-PLA(2) makes it possible to use a single measurement in clinical decision making, and it also permits clinicians to follow the Lp-PLA(2) marker serially. Ultimately, Lp-PLA(2) may also be classified as a risk factor, but this should not detract from its utility today as a risk marker.

    would be cardioprotective. When LDL cholesterol is aggressively lowered to targets, low HDL cholesterol levels are still inversely related to MCVE. The efflux capacity, or ability to relocate cholesterol out of macrophages, is believed to be a major antiatherogenic mechanism responsible for reduction in MCVE mediated in part by healthy HDL. HDL cholesterol is a complex molecule with antioxidative, anti-inflammatory, antithrombotic, antiplatelet, and vasodilatory properties, among which is protection of LDL from oxidation. HDL-associated paraoxonase-1 has a major effect on endothelial function. Further, HDL promotes endothelial repair and progenitor cell health, and supports production of nitric oxide. HDL from patients with cardiovascular disease, diabetes, and autoimmune disease may fail to protect or even become proinflammatory or pro-oxidant. Mendelian randomization and other clinical studies in which raising HDL cholesterol has not been beneficial suggest that high plasma levels do not necessarily reduce cardiovascular risk. These data, coupled with extensive preclinical information about the functional heterogeneity of HDL, challenge the “HDL hypothesis”, ie, raising HDL cholesterol per se will reduce MCVE. After the equivocal AIM-HIGH (Atherothrombosis Intervention in Metabolic Syndrome With Low HDL/High Triglycerides: Impact on Global Health Outcomes study and withdrawal of two major cholesteryl ester transfer protein compounds, one for off-target adverse effects and the other for lack of efficacy, development continues for two other agents, ie, anacetrapib and evacetrapib, both of which lower LDL cholesterol substantially. The negative but controversial HPS2-THRIVE (the Heart Protection Study 2-Treatment of HDL to Reduce the Incidence of Vascular Events trial casts further doubt on the HDL cholesterol hypothesis. The growing impression that HDL functionality, rather than abundance, is clinically important is supported by experimental evidence highlighting

    The objective of this study is to explore the cause of early abnormal muscle response (AMR) disappearance during microvascular decompression for hemifacial spasm and the clinical outcomes of these patients. Three hundred seventy-two patients received microvascular decompression (MVD) under intraoperative electrophysiological monitoring in Nanjing Drum Tower Hospital in 2014; the characteristic AMR of HFS was observed in 359 patients during the operation. And the 359 patients were divided into two groups based on whether AMR had remained before the beginning of the decompression procedure for offending vessels. Thirty-three patients who showed a permanent disappearance of AMR before the beginning of decompression were regarded as group I. Dural opening and the succeeding CSF drainage produced a permanent disappearance of AMR in 13. During the dissection of lateral cerebellomedullary cistern, a permanent disappearance of AMR was found in 20 patients. Thirty-two patients were cured immediately; delayed resolution (7 days after surgery) was found in one patient. No complications were observed and no recurrence was found during the follow-up period in the 33 patients. In the other 326 patients (group II), AMR disappeared temporarily before the beginning of the decompression procedure for offending vessels in 42 patients. After decompression, AMR disappeared completely in 305 patients. Two hundred sixty-seven patients were cured immediately and 57 patients got a delayed resolution (2 days to 45 weeks after surgery). The two left did not get a complete abolition of spasm. Three cases of hearing loss, one hoarseness, and nine delayed facial paralysis were observed. The reason of early abnormal muscle response disappearance may be that the degree of neurovascular compression was not serious; these patients were more likely to get an immediate cure. Continuous intraoperative electrophysiological monitoring of AMR is necessary.

    3D-printed models fabricated from CT, MRI, or echocardiography data provide the advantage of haptic feedback, direct manipulation, and enhanced understanding of cardiovascular anatomy and underlying pathologies. Reported applications of cardiovascular 3D printing span from diagnostic assistance and optimization of management algorithms in complex cardiovascular diseases, to planning and simulating surgical and interventional procedures. The technology has been used in practically the entire range of structural, valvular, and congenital heart diseases, and the added-value of 3D printing is established. Patient-specific implants and custom-made devices can be designed, produced, and tested, thus opening new horizons in personalized patient care and cardiovascular research. Physicians and trainees can better elucidate anatomical abnormalities with the use of 3D-printed models, and communication with patients is markedly improved. Cardiovascular 3D bioprinting and molecular 3D printing, although currently not translated into clinical practice, hold revolutionary potential. 3D printing is expected to have a broad influence in cardiovascular care, and will prove pivotal for the future generation of cardiovascular imagers and care providers. In this Review, we summarize the cardiovascular 3D printing workflow, from image acquisition to the generation of a hand-held model, and discuss the cardiovascular applications and the current status and future perspectives of cardiovascular 3D printing.

    The microbiota inhabiting the human gastro-intestinal tract is reported to have a significant impact on the health of an individual. Recent findings suggest that the microbial imbalance of the gut may play a role in pathogenesis of cardiovascular diseases (CVD). Therefore, several studies have delved into the aspect of altering gut microbiota with probiotics as an approach to prevent and/or treat CVD. The World Health Organization defines probiotics as live microorganisms that, when consumed in adequate amounts, have a positive influence on the individual's health. The present review focuses on strategies of human dietary intervention with probiotic strains and their impact on cardiovascular risk factors like hypercholesterolemia, hypertension, obesity and type-2 diabetes. Accumulating evidence shows probiotics to lower low density lipoproteins (LDL)-cholesterol and improve the LDL/high density lipoproteins (HDL) ratio, as well as lower blood pressure, inflammatory mediators, blood glucose levels and body mass index. Thus, probiotics have the scope to be developed as dietary supplements with potential cardiovascular health benefits. However, there is not only ambiguity regarding the exact strains and dosages of the probiotics that will bring about positive health effects, but also factors like immunity and genetics of the individual that might influence the efficacy of probiotics. Therefore, further studies are required not only to understand the mechanisms by which probiotics may beneficially affect the cardiovascular system, but also to rule out any of their probable negative effects on health. The present review aims to critically appraise the complexity of the available data with regard to the cardiovascular benefits of probiotics.

    Polycystic ovary syndrome (PCOS) is associated with a clustering of metabolic and cardiovascular risk factors. Insulin resistance is implicated as the major player in the metabolic abnormalities and contributes to the increased cardiovascular risk associated with the syndrome. However, androgen excess appears to participate as an independent parameter, which further aggravates the cardiovascular and metabolic aberrations in affected women with PCOS. The resultant impact of hyperandrogenemia possibly acquires clinical significance for women's health in the context of PCOS, particularly since recent data support an increased incidence of coronary artery disease and of cardiovascular events directly related to androgen levels in women with the syndrome.

    Though cortical abnormalities have been demonstrated in moderate and severe traumatic brain injured (TBI) patients, there have been no studies examining cortical changes following blast related mild TBI (mTBI). The purpose of this study was to determine the effects and functional relevance of blast mTBI on cortical thickness in a small cohort of carefully screened blast injured US Service Members (SM). Twelve SM with mTBI acquired through blast injury were compared to 11 demographically matched control SM without TBI. Both mTBI and control participants were active duty and had completed a combat deployment. Subjects underwent MRI examination and the T1 weighted anatomic images were processed using the FreeSurfer suite of tools. Cortical thickness maps were compared between groups and examined for relationships with time since injury (TSI). Utilizing a large database of functional imaging results (BrainMap), significant regions of interest (ROI) were used to determine the behavioral profiles most consistently associated with the specific ROI. In addition, clinical variables were examined as part of post-hoc analysis of functional relevance. Group comparisons controlling for age demonstrated several significant clusters of cortical thinning for the blast injured SM. After multiple comparisons correction (False Discovery Rate (FDR)), two left hemisphere clusters remained significant (left superior temporal (STG) and frontal (SFG) gyri). No clusters were significantly correlated with TSI after FDR correction. Behavioral analysis for the STG and SFG clusters demonstrated three significant behavioral/cognitive sub-domains, each associated with audition and language. Blast injured SMs demonstrated distinct areas of cortical thinning in the STG and SFG. These areas have been previously shown to be associated with audition and language. Post-hoc analyses of clinical records demonstrated significant abnormal audiology reports for the blast injured SM suggesting that the

    Full Text Available Background and objective Pulmonary hypertension (PH often leads to dilatation of main pulmonary artery (MPA. MPA measurements can be used to predict PH. This aim of this study is to investigate power of MPA vessel indices, which are acquired from cardiovascular magnetic resonance, to evaluate PH. Methods Cardiovascular-magnetic-resonance-determined parameters of MPA were acquired and calculated in 83 PH patients, whose diagnosis were confirmed with right heart catheterization and 49 healthy volunteers; these parameters included MPA diameter (DPA, ratio of DPA and ascending aorta diameter (DPA/DAo, max mean diameter (MDmax, min mean diameter (MDmin, fraction transverse diameter (fTD, fraction longitudinal diameter (fLD, and distensibility. Results Compared with control group, DPA, DPA/DAo, MDmax, and MDmin were significantly higher in patients with PH (P28.4 mm, and MDmax>32.4 mm (area under the curve, AUC=0.979, 0.981 showed best performance in predicting PH, yielding highest specificity at 100%. Conclusion Noninvasive cardiovascular-magnetic-resonance-derived MPA measurements provide excellent and practical reference in clinical settings for detecting PH.

    Many existing and emerging cancer therapies have significant impact on the cardiovascular (CV) health of patients with cancer and cancer survivors. This manuscript examines current aspects of interdisciplinary cardio-oncology clinical care delivery and education in the United States and outlines how these data provide a platform for future development of the field. We present the results of the nationwide survey on cardio-oncology services, practices and opinions, conducted among Chiefs of Cardiology and Program Directors, that demonstrate ranges of clinical activities and identify significant interest for increased educational opportunities and expert training of CV physicians in this field. The survey respondents recognized clinical relevance, but emphasized lack of national guidelines, lack of funds, and limited awareness and infrastructure as the main challenges for development and growth of cardio-oncology. We discuss potential solutions to unmet needs through interdisciplinary collaboration and the active roles of professional societies and other stakeholders. PMID:26112199

    Full Text Available Background: The aging process promotes a progressive increase in chronic-degenerative diseases. The effect of these diseases on the functional capacity has been well recognized. Another health parameter concerns “quality of life related to health”. Among the elderly population, cardiovascular diseases stand out due to the epidemiological and clinical impact. Usually, these diseases have been associated with others. This set of problems may compromise both independence and quality of life in elderly patients who seek cardiologic treatment. These health parameters have not been well contemplated by cardiologists. Objective: Evaluating, among the elderly population with cardiovascular disease, which are the most relevant clinical determinants regarding dependence and quality of life. Methods: This group was randomly and consecutively selected and four questionnaires were applied: HAQ, SF-36, PRIME-MD e Mini Mental State. Results: The study included 1,020 elderly patients, 63.3% women. The group had been between 60 and 97 years-old (mean: 75.56 ± 6.62 years-old. 61.4% were independent or mild dependence. The quality of life total score was high (HAQ: 88.66 ± 2.68. 87.8% of patients had a SF-36 total score > 66. In the multivariate analysis, the association between diagnoses and high degrees of dependence was significant only for previous stroke (p = 0.014, obesity (p < 0.001, lack of physical activity (p = 0.016, osteoarthritis (p < 0.001, cognitive impairment (p < 0.001, and major depression (p < 0.001. Analyzing the quality of life, major depression and physical illness for depression was significantly associated with all domains of the SF-36. Conclusion: Among an elderly outpatient cardiology population, dependence and quality of life clinical determinants are not cardiovascular comorbidities, especially the depression.

    This review focuses on the mechanisms by which thyroid hormones affect the regulation of the cardiovascular system and the thermogenic and hemodynamic variation induced by thyroid disfunction. It is also stressed the hormonal role of the cardiac myocytes realising natriuretic peptides, involved in plasma volume homeostasis and cardiovascular remodelling; its rapid measurement is a useful clinical tool, in the diagnostic and prognostic of left ventricular dysfunction, correlating with the degree of the clinical symptoms. The endothelial layer is a receptor-effector endocrine organ that produces substances that maintain vasomotor balance and vascular-tissue homeostasis. Cardiovascular risk factors causes oxidative stress that alter endothelial function and leads to endothelial dysfunction. On the basis of the present body of evidence there is no doubt that endothelial dysfunction contributes to the initiation, and progression, of atherosclerotic disease and that it could be considered an independent vascular risk factor for the micro- and macrovascular damages in the diabetes disease. In several extrathyroidal pathological condition, as well as in heart failure, the main alteration of the thyroid function is referred to as "low T3 syndrome". This syndrome is due to an adaptative reaction of the metabolic pathway of thyroxine, producing an increased amount of rT3, metabolically inactive, thus decreasing the detrimental metabolic effects of T3, in conditions of critically impaired hemodynamic and metabolic efficiency. Preliminary clinical trials, in heart failure, suggest the prognostic value of the level of circulating T3, as well as usefulness of T3, or of thyromimetic derivatives (DITPA), in chronic treatment of the heart ventricular dysfunction.

    cholesterol levels are still inversely related to MCVE. The efflux capacity, or ability to relocate cholesterol out of macrophages, is believed to be a major antiatherogenic mechanism responsible for reduction in MCVE mediated in part by healthy HDL. HDL cholesterol is a complex molecule with antioxidative, anti-inflammatory, anti-thrombotic, antiplatelet, and vasodilatory properties, among which is protection of LDL from oxidation. HDL-associated paraoxonase-1 has a major effect on endothelial function. Further, HDL promotes endothelial repair and progenitor cell health, and supports production of nitric oxide. HDL from patients with cardiovascular disease, diabetes, and autoimmune disease may fail to protect or even become proinflammatory or pro-oxidant. Mendelian randomization and other clinical studies in which raising HDL cholesterol has not been beneficial suggest that high plasma levels do not necessarily reduce cardiovascular risk. These data, coupled with extensive preclinical information about the functional heterogeneity of HDL, challenge the "HDL hypothesis", ie, raising HDL cholesterol per se will reduce MCVE. After the equivocal AIM-HIGH (Atherothrombosis Intervention in Metabolic Syndrome With Low HDL/High Triglycerides: Impact on Global Health Outcomes) study and withdrawal of two major cholesteryl ester transfer protein compounds, one for off-target adverse effects and the other for lack of efficacy, development continues for two other agents, ie, anacetrapib and evacetrapib, both of which lower LDL cholesterol substantially. The negative but controversial HPS2-THRIVE (the Heart Protection Study 2-Treatment of HDL to Reduce the Incidence of Vascular Events) trial casts further doubt on the HDL cholesterol hypothesis. The growing impression that HDL functionality, rather than abundance, is clinically important is supported by experimental evidence highlighting the conditional pleiotropic actions of HDL. Non-HDL cholesterol reflects the cholesterol in all

    Native valve infective endocarditis (IE) in patients with normal valves has increased in the last decades. Whether patients with normal valves present a similar prognosis to those with pathologic valves is unresolved. Our aim is to describe epidemiologic and clinical differences between patients with left-sided IE and normal valves and those with native pathologic valves. We analyzed 945 consecutive episodes of IE, 435 of which involved left-sided nonprosthetic IE. They were classified into 2 groups: episodes in normal valves (normal group, n=173) and episodes in pathologic valves (abnormal group, n=262). Patients in the normal group were younger, Staphylococcus aureus and Streptococcus bovis were more frequently isolated, and vegetations were more frequently found. Heart failure, septic shock, and the need for surgery or death were more common. Multivariate analysis identified the following as factors independently associated with normal valve IE: agevalve IE, patients with IE on normal valves were younger, had a more virulent microbiological profile, developed heart failure and septic shock more frequently, needed more surgical procedures, and had worse prognosis.

    . Furthermore, MDA mimotopes were found to mimic MDA epitopes on the surface of apoptotic cells. Immunization of mice with P2 resulted in the induction of MDA-LDL-specific Abs, which strongly immunostained human atherosclerotic lesions. We detected IgG and IgM autoAbs to both MDA mimotopes in sera of healthy....... These mimotopes can serve as standardized and reproducible antigens that will be useful for diagnostic and therapeutic applications in cardiovascular disease....

    The VI European Guidelines for Cardiovascular Prevention recommend combining population and high-risk strategies with lifestyle changes as a cornerstone of prevention, and propose the SCORE function to quantify cardiovascular risk. The guidelines highlight disease specific interventions, and conditions as women, young people and ethnic minorities. Screening for subclinical atherosclerosis with noninvasive imaging techniques is not recommended. The guidelines distinguish four risk levels (very high, high, moderate and low) with therapeutic objectives for lipid control according to risk. Diabetes mellitus confers a high risk, except for subjects with type 2 diabetes with less than <10 years of evolution, without other risk factors or complications, or type 1 diabetes of short evolution without complications. The decision to start pharmacological treatment of arterial hypertension will depend on the blood pressure level and the cardiovascular risk, taking into account the lesion of target organs. The guidelines don't recommend antiplatelet drugs in primary prevention because of the increased bleeding risk. The low adherence to the medication requires simplified therapeutic regimes and to identify and combat its causes. The guidelines highlight the responsibility of health professionals to take an active role in advocating evidence-based interventions at the population level, and propose effective interventions, at individual and population level, to promote a healthy diet, the practice of physical activity, the cessation of smoking and the protection against alcohol abuse.

    Human genetic variation in the form of single nucleotide polymorphisms as well as more complex structural variations such as insertions, deletions and copy number variants, is partially responsible for the clinical variation seen in response to pharmacotherapeutic drugs. This affects the likelihood of experiencing adverse drug reactions and also of achieving therapeutic success. In this paper, we review key studies in cardiovascular pharmacogenetics that reveal genetic variations underlying the outcomes of drug treatment in cardiovascular disease. Examples of genetic associations with drug efficacy and toxicity are described, including the roles of genetic variability in pharmacokinetics (e.g. drug metabolizing enzymes) and pharmacodynamics (e.g. drug targets). These findings have functional implications that could lead to the development of genetic tests aimed at minimizing drug toxicity and optimizing drug efficacy in cardiovascular medicine.

    Full Text Available Reduction of LDL-cholesterol concentration in serum, blocking the isoprenylation of GTPases and the activation of myocyte-protective enzyme systems are three mechanisms that currently explain the lipid and non-lipid effects of statins. However, the decrease of LDL-cholesterol, the reduction of inflammation biomarkers and even the atheroregresion, as surrogate effects to the mechanisms of action of statins would be irrelevant if not accompanied by a significant decrease in the incidence of cardiovascular events. Statins like no other pharmacological group have proven to reduce the incidence of cardiovascular events and prolong life in any clinical scenario.

The mean (log ages were different and were found to be 28.80 ± 0.49 years versus 35.02 ± 0.39 years (P < 0.0001, respectively. Of the opiate dependent group, 87.7% were treated with buprenorphine, 8.8% with methadone, and 3.4% with naltrexone. Multiple regression analysis was used to adjust for chronologic age (CA. At CA of 60 years, the modeled age in the controls was 66.40 years, and that in the addicted group was 73.11 years, an advancement of 6.71 years, or 10.10%. Exacerbations of age dependent changes in central arterial stiffness, central pressures, pulse rate, ejection duration, diastolic duration, and subendocardial perfusion ratio by opiate dependence were all noted (P < 0.05. Current heroin dose, heroin duration, and the dose duration interaction were all significantly related to the vascular (or “reference” age (RA/CA ratio (all P < 0.006. After multivariate adjustment, the opiate dose duration was independently predictive of RA (P < 0.02.

In this naturalistic study we investigated a sample of 809 antipsychotic-treated patients from Swedish psychosis outpatient teams. Cardiovascular risk factors (eg, metabolic syndrome, homeostasis model assessment of insulin resistance, and low-density lipoprotein values were measured, and their associations to current antipsychotic pharmacotherapy were studied. Ten antipsychotic drugs were compared in a stepwise logistic regression model. For the patients, the presence of the components of metabolic syndrome ranged from 35% for hyperglycemia to 64% for elevated waist circumference. Hypertriglyceridemia was associated with clozapine (odds ratio [OR] = 1.81, 95% confidence interval [CI] 1.08–3.04, reduced high-density lipoprotein with both clozapine and olanzapine (OR = 1.73, 95% CI 1.01–2.97; and OR = 2.03, 95% CI 1.32–3.13, hypertension with perphenazine (OR = 2.00, 95% CI 1.21–3.59, and hyperglycemia inversely with ziprasidone (OR = 0.21, 95% CI 0.05–0.89 and positively with haloperidol (OR = 2.02, 95% CI 1.18–3.48.

    The objective of this systematic review was to determine if dairy product consumption is detrimental, neutral, or beneficial to cardiovascular health and if the recommendation to consume reduced-fat as opposed to regular-fat dairy is evidence-based. A systematic review of meta-analyses of prospective population studies associating dairy consumption with cardiovascular disease (CVD), coronary artery disease (CAD), stroke, hypertension, metabolic syndrome (MetS), and type 2 diabetes (T2D) was conducted on the basis of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Quality of evidence was rated by using the Grading of Recommendations Assessment, Development, and Evaluation scale. High-quality evidence supports favorable associations between total dairy intake and hypertension risk and between low-fat dairy and yogurt intake and the risk of T2D. Moderate-quality evidence suggests favorable associations between intakes of total dairy, low-fat dairy, cheese, and fermented dairy and the risk of stroke; intakes of low-fat dairy and milk and the risk of hypertension; total dairy and milk consumption and the risk of MetS; and total dairy and cheese and the risk of T2D. High- to moderate-quality evidence supports neutral associations between the consumption of total dairy, cheese, and yogurt and CVD risk; the consumption of any form of dairy, except for fermented, and CAD risk; the consumption of regular- and high-fat dairy, milk, and yogurt and stroke risk; the consumption of regular- and high-fat dairy, cheese, yogurt, and fermented dairy and hypertension risk; and the consumption of regular- and high-fat dairy, milk, and fermented dairy and T2D risk. Data from this systematic review indicate that the consumption of various forms of dairy products shows either favorable or neutral associations with cardiovascular-related clinical outcomes. The review also emphasizes that further research is urgently needed to compare the impact of

    Iopamidol, a new non-ionic water-soluble contrast medium, has been compared with standard ionic media in a number of cardiovascular applications. It is stable in aqueous solution, is much less viscous and only slightly more osmolar than metrizamide. Compared to sodium meglumine diatrizoate in a series of 40 coronary arteriograms, it produced a consistent and highly significant decrease in the incidence and severity of hypotension and bradycardia following intracoronary injection. In the same group and in 62 children undergoing ventricular or great vessel angiocardiography, a subjective assessment of patient reaction showed that iopamidol was better tolerated than the ionic medium. There was a very strong patient preference for iopamidol in a group of 20 of the adult patients who had also consented to femoral artery injections of both media. Throughout these series there was no detectable difference in arterial image quality between the media. Venous phase opacification during arterioportography was assessed in 11 cases comparing iopamidol with sodium meglumine iothalamate. No significant difference was found. We conclude that iopamidol is clearly preferable to ionic media for routine cardiovascular applications.

    Background Erectile dysfunction (ED) is especially common in men with major depressive disorder (MDD). This study examined the extent to which risk factors for cardiovascular disease (CVD) and vascular dysfunction were associated with ED severity in a series of MDD patients. Methods The sample included 46 middle-aged [M (SD) age = 53 (7)], sedentary men diagnosed with MDD. ED severity was assessed by the Arizona Sexual Experiences Scale (ASEX), item 3. Depression severity was measured by the Beck Depression Inventory (BDI). CVD risk factors were quantitated by the Framingham Cardiovascular Disease Risk Profile score. Vascular function was measured by flow-mediated dilation (FMD) of the brachial artery. Results The average ASEX score for this sample was 3.2 (SD = 1.2). Regression analysis revealed that ASEX scores were predicted by greater CVD risk factors (p = .008, β = .41) and lower FMD (p = .03, β = −.33). When FMD was included in the regression model, the relationship between CVD risk factors and ASEX scores was partially attenuated (p = .08, β = .28). Conclusions ED was associated with CVD risk and impaired vascular function, although it appears that CVD risk factors may affect ED through impairment of vascular functioning. PMID:19776749

    Childhood overweight (body mass index (BMI)>90th centile) poses a major public health problem in so far as adult diseases manifest themselves already during childhood. In this review, after examining the prevalence of metabolic and cardiovascular diseases, the issue of whether BMI or other clinical parameters are valid tools to predict co-morbidities in children is discussed. Data of 2001-2008 are reviewed, including several studies conducted on more than 260,000 overweight and obese children in Germany and Switzerland. Apart from non-metabolic co-morbidities, namely musculoskeletal complications and attention deficit/hyperactivity disorders in up to 74% and up to 58% of overweight children, respectively, at least one cardiovascular and metabolic risk factor was seen in 52% of the overweight children, mostly high blood pressure (35%) with increased left ventricular mass or arterial stiffness. Signs of fatty liver disease or dyslipidemia were found in up to 29 and 32% of the children, respectively. Type 2 diabetes was found in less than 0.7% of the children, and an elevated fasting glucose or glucose intolerance in 3%. Irrespective of BMI, the quality of fat and protein intake predicted hypertension or insulin resistance, and fructose predicted lower (and more atherogenic) particle size of low-density lipoprotein-cholesterol. Out of the adiposity markers, waist circumference was closely correlated with insulin resistance and the components of the metabolic syndrome. In conclusion, risk factors are found in more than half of the overweight children, most frequently high blood pressure or dyslipidemia, and were mainly related to waist circumference, but also to BMI and fat mass. Even in the presence of normal BMI, screening for cardiovascular risk factors is advocated in each child with elevated waist circumference, but its cut-off points still remain to be validated. The increased occurrence of orthopedic and psychiatric complaints may detrimentally influence health

    Previous studies have suggested that subclinical thyroid dysfunction, as manifested by abnormalities in thyroid-stimulating hormone (TSH) levels, are associated with detrimental effects on the cardiovascular system. Subclinical hypothyroidism is characterized by abnormal lipid metabolism, cardiac dysfunction, diastolic hypertension conferring an elevated risk of atherosclerosis, and ischemic heart disease. Similarly, patients with subclinical hyperthyroidism have nearly 3 times the likelihood of atrial fibrillation over a 10-year follow-up interval, raising the question of whether patients with subclinical hyperthyroidism should be treated to prevent atrial fibrillation. A single measurement of low serum TSH in individuals aged 60 years or older has been reported to be associated with increased mortality from all causes and in particular from circulatory and cardiovascular disease in a 10-year follow-up study. Subclinical thyroid dysfunction is currently the subject of numerous studies and remains controversial, particularly as it relates to cardiovascular morbidity and mortality and clinical applications.

    Importance While progress continues to be made in the field of stem cell regenerative medicine for the treatment of cardiovascular disease, significant barriers to clinical translation still exist that have thwarted the delivery of cell therapy to the bedside. Objective The purpose of this review is to summarize the major current hurdles for the clinical implementation of stem cell therapy and discuss potential strategies to overcome them. Evidence Review Information for this review was obtained through a search of PubMed and the Cochrane database for English language studies published between January 1, 2000 and June 15, 2016. Ten randomized clinical trials and eight systematic reviews were included in this review. Findings One of the major clinical hurdles facing the routine implementation of stem cell therapy is the limited and inconsistent benefit observed thus far. Reasons for this are unclear but may be due to poor cell retention and survival, as suggested by numerous preclinical studies and a handful of human studies incorporating cell fate imaging. Additional cell fate imaging studies in humans are needed to determine how these factors contribute to limited efficacy. Treatment strategies to address poor cell retention and survival are under investigation and include the following: 1) co-administering of immunosuppressive and pro-survival agents, 2) delivering cardioprotective factors packaged in exosomes rather than the cells themselves, and 3) using tissue engineering strategies to provide structural support for cells. If larger grafts are achieved using the aforementioned strategies, it will be imperative to carefully monitor the potential risks of tumorigenicity, immunogenicity, and arrhythmogenicity. Conclusions and Relevance Despite important achievements to date, stem cell therapy is not yet ready for routine clinical implementation. Significant research is still needed to address the clinical hurdles outlined herein before the next wave of large

    Late-onset noninfectious pulmonary complications (LONIPCs) are life-threatening complications of bone marrow transplantation (BMT). Several pathological patterns are described in the literature with different prognoses, and with different relationships to graft-versus-host disease (GVHD). The role of high-resolution CT (HRCT) is not yet well established. To illustrate different patterns of LONIPCs on HRCT in allogeneic versus autologous BMT in order to investigate the correlation with chronic GVHD (cGVHD). A total of 67 HRCT scans were performed in 24 patients with noninfectious pulmonary disease at least 3 months after BMT (16 allogeneic, 8 autologous). Abnormality patterns and extension on HRCT images were correlated with the clinical outcome and with the severity of cGVHD. Of 24 patients, 9 showed LONIPCs (1 autologous, 8 allogeneic). There was a significant association between abnormalities on HRCT and severe cGVHD (P = 0.038), with no specific pattern. Prognosis seemed to be related to the severity of cGVHD and not to the extent of abnormalities on HRCT. The significant association between abnormalities on HRCT and severe GVHD suggests that LONIPCs can be a pulmonary manifestation of the disease. HRCT is a useful tool when combined with clinical data. (orig.)

    During the last several last decades, reduction in lipids has been the main focus to decrease the risk of coronary heart disease (CHD). Several lines of evidence, however, have indicated that lipids account only for the PLA(2)) is a novel inflammatory biomarker that can provide much needed information about plaque inflammation and plaque stability. Lp-PLA(2) is among the multiple biomarkers that have been associated with increased CHD risk. In this present work, we review the evidence from previous studies addressing the effect of different therapies on decreasing Lp-PLA(2) and the role of direct Lp-PLA(2) inhibitors. This work also briefly reviews the evidence of Lp-PLA(2) clinical utility as a potential marker of vascular inflammation and formation of rupture prone plaques. Additionally, we also discuss the implication of available evidence in context of current cardiovascular inflammatory biomarkers recommendations and the evidence from epidemiologic studies addressing the relationship of Lp-PLA(2) and risk of cardiovascular disease.

    Background: Few data exist regarding cardiovascular risk among HIV-infected patients attending sexual health clinics (SHC) in Australia. Methods: The medical records of 188 patients attending an inner-city SHC between August 2013 and July 2014 were retrospectively reviewed for cardiovascular risk factors and associated screening and management practices. Results: Cardiovascular risk factors were common among attendees of the SHC, including smoking (38%), hypertension (14%) and dyslipidaemia (11%). Of the 188 patients, 23% reported using potentially cardiotoxic recreational drugs, 25% of dyslipidaemic patients were not on therapy and 10% of patients were hypertensive; none were prescribed treatment. A smoking cessation program was offered to all patients. Conclusion: A high prevalence of risk factors for cardiovascular disease was demonstrated. Modification of risk factors could be improved.

    Sauna therapy has been used for hundreds of years in the Scandinavian region as a standard health activity. Studies document the effectiveness of sauna therapy for persons with hypertension, congestive heart failure, and for post-myocardial infarction care. Some individuals with chronic obstructive pulmonary disease (COPD), chronic fatigue, chronic pain, or addictions also find benefit. Existing evidence supports the use of saunas as a component of depuration (purification or cleansing) protocols for environmentally-induced illness. While far-infrared saunas have been used in many cardiovascular studies, all studies applying sauna for depuration have utilized saunas with radiant heating units. Overall, regular sauna therapy (either radiant heat or far-infrared units) appears to be safe and offers multiple health benefits to regular users. One potential area of concern is sauna use in early pregnancy because of evidence suggesting that hyperthermia might be teratogenic.

    The 2014 i2b2 natural language processing shared task focused on identifying cardiovascular risk factors such as high blood pressure, high cholesterol levels, obesity and smoking status among other factors found in health records of diabetic patients. In addition, the task involved detecting medications, and time information associated with the extracted data. This paper presents the development and evaluation of a natural language processing (NLP) application conceived for this i2b2 shared task. For increased efficiency, the application main components were adapted from two existing NLP tools implemented in the Apache UIMA framework: Textractor (for dictionary-based lookup) and cTAKES (for preprocessing and smoking status detection). The application achieved a final (micro-averaged) F1-measure of 87.5% on the final evaluation test set. Our attempt was mostly based on existing tools adapted with minimal changes and allowed for satisfying performance with limited development efforts.

    Full Text Available The peroxisome proliferator-activated receptors (PPARs consist of three related transcription factors that serve to regulate a number of cellular processes that are central to cardiovascular health and disease. Numerous pharmacologic studies have assessed the effects of specific PPAR agonists in clinical trials and have provided insight into the clinical effects of these genes while genetic studies have demonstrated clinical associations between PPAR polymorphisms and abnormal cardiovascular phenotypes. With the abundance of data available from these studies as a background, PPAR pharmacogenetics has become a promising and rapidly advancing field. This review focuses on summarizing the current state of understanding of PPAR genetics and pharmacogenetics and the important implications for the individualization of therapy for patients with cardiovascular diseases.

    Full Text Available Background: Infertility is a common gynaecological problem and male factor contributes significantly in the aetiology of infertility. Semen analysis has remained a useful investigation in the search for male factor infertility. Aim: This study assessed the pattern of semen parameters and predictive factors associated with abnormal parameters in male partners of infertile couples attending a Nigerian tertiary hospital. Methods: A descriptive study of infertile couples presenting at the clinic between January 2012and December 2015 was done at Ekiti State University Teaching Hospital, Ado-Ekiti. Seminal fluid from the male partners were analysed in the laboratory using the WHO 2010 criteria for human semen characteristics. Data was analysed using SPSS 17 and logistic regression analysis was used to determine the predictive factors associated with abnormal semen parameters. Results: A total of 443 men participated in the study and 38.2% had abnormal sperm parameters. Oligozoospermia (34.8% and asthenozoospermia (26.9% are leading single factor abnormality found, astheno-oligozoospermia occurred in 14.2% and oligo-astheno-teratozoospermia in 3.6% of cases. The prevalence of azoospermia was 3.4%. Smoking habit, past infection with mumps and previous groin surgery significantly predicted abnormal semen parameters with p values of 0.025, 0.040 and 0.017 respectively. Positive cultures were recorded in 36.2% of cases and staph aureus was the commonest organism. Conclusion: Male factor abnormalities remain significant contributors to infertility and men should be encouraged through advocacy to participate in investigation of infertility to reduce the level of stigmatization and ostracizing of women with infertility especially in sub-Saharan Africa.

    Full Text Available  Aim. To assess real clinical practice of prescribing beta-blockers (BB and its compliance with updated guidelines, using data from outpatient registers that are carried out in medical institutions of different levels. Material and methods. We analyzed data from two outpatient registries - RECVASA and PROFILE. RECVASA register included patients aged ≥18 years with arterial hypertension (HT, ischemic heart disease (IHD, chronic heart failure (CHF and atrial fibrillation (AF that consulted in 3 outpatient clinics of Ryazan city in 2012-2013 (n=3690. PROFILE register included patients aged ≥18 years with HT, IHD, CHF, AF that consulted in specialized cardiac unit of the State Research Center for Preventive Medicine in 2011-2015 (n=1531. Results. There were differences in the basic characteristics of the registers: in the RECVASA register average age of patients was higher, HT, IHD and CHF were more frequent; PROFILE register included more patients with the history of myocardial infarction. In the RECVASA register 41.5% (n=1533 of patients received BB, and in the PROFILE register – 47.7% (n=731. The most frequently prescribed BB was bisoprolol in all cardiovascular diseases. Conclusion. In a specialized medical institution BB used more often under the conditions where they are necessary. The choice of a specific BB inside the pharmacological group, even in a specialized medical institution does not always correspond to clinical guidelines and evidence-based medicine.

    Full Text Available In this paper we comprehensively review published quantitative research on the relationship between religion, spirituality (R/S, and cardiovascular (CV disease, discuss mechanisms that help explain the associations reported, examine the clinical implications of those findings, and explore future research needed in Brazil on this topic. First, we define the terms religion, spirituality, and secular humanism. Next, we review research examining the relationships between R/S and CV risk factors (smoking, alcohol/drug use, physical inactivity, poor diet, cholesterol, obesity, diabetes, blood pressure, and psychosocial stress. We then review research on R/S, cardiovascular functions (CV reactivity, heart rate variability, etc., and inflammatory markers (IL-6, IFN-γ, CRP, fibrinogen, IL-4, IL-10. Next we examine research on R/S and coronary artery disease, hypertension, stroke, dementia, cardiac surgery outcomes, and mortality (CV mortality in particular. We then discuss mechanisms that help explain these relationships (focusing on psychological, social, and behavioral pathways and present a theoretical causal model based on a Western religious perspective. Next we discuss the clinical applications of the research, and make practical suggestions on how cardiologists and cardiac surgeons can sensitively and sensibly address spiritual issues in clinical practice. Finally, we explore opportunities for future research. No research on R/S and cardiovascular disease has yet been published from Brazil, despite the tremendous interest and involvement of the population in R/S, making this an area of almost unlimited possibilities for researchers in Brazil.

    Full Text Available BACKGROUND AND OBJECTIVES Abnormal Uterine Bleeding (AUB is a very frequent gynaecological complaint and occurs across the entire age spectrum, approximately 75000 hysterectomies are carried out each year with 30% of these for menstrual problems alone. These menstrual aberrations occur more commonly at extremes of reproductive life. The introduction of hysteroscopy has opened a new dimension in evaluation of patient with AUB replacing the blind technique of Dilatation and Curettage. The present study was undertaken to know the accuracy of various tests with Histopathology. MATERIALS AND METHODS The present prospective study was carried out on 100 patients from reproductive, perimenopausal and postmenopausal age group with abnormal uterine bleeding in Dr. B. R. Ambedkar Medical College and Hospital. RESULTS In the present study, in relation to histopathological examination, clinical findings and hysteroscopy had better accuracy (72% as compared to ultrasound findings (41% in diagnosis of abnormal uterine bleeding. CONCLUSION Hysteroscopy guided biopsy and histopathology complements each other in the evaluation of patient with abnormal uterine bleeding for accurate diagnosis and further treatment.

    2015-12-01

    Full Text Available Introduction: Strategies to identify high-risk emergency department (ED patients often use markedly abnormal vital signs and serum lactate levels. Risk stratifying such patients without using the presence of shock is challenging. The objective of the study is to identify independent predictors of in-hospital adverse outcomes in ED patients with abnormal vital signs or lactate levels, but who are not in shock. Methods: We performed a prospective observational study of patients with abnormal vital signs or lactate level defined as heart rate ≥130 beats/min, respiratory rate ≥24 breaths/min, shock index ≥1, systolic blood pressure 4.0mmol/L (OR 5.1, 95% CI [2.1–12.2], age ≥80 yrs (OR 1.9, CI [1.0–3.7], bicarbonate <21mEq/L (OR 2.5, CI [1.3–4.9], and initial HR≥130 (OR 3.1, CI [1.5–6.1]. Conclusion: Patients exhibiting abnormal vital signs or elevated lactate levels without shock had significant rates of deterioration after hospitalization. ED clinical data predicted patients who suffered adverse outcomes with reasonable reliability.

    Clinical risk-prediction models serve an important role in healthcare. They are used for clinical decision-making and measuring the performance of healthcare providers. To establish confidence in a model, external model validation is imperative. When designing such an external model validation study, thought must be given to patient selection, risk factor and outcome definitions, missing data, and the transparent reporting of the analysis. In addition, there are a number of statistical methods available for external model validation. Execution of a rigorous external validation study rests in proper study design, application of suitable statistical methods, and transparent reporting.

    Full Text Available Background: Patients with schizophrenia (SZ are generally overweight or obese and have several metabolic disorders. Additionally, such patients have a lower life expectancy and the main cause of their increased mortality is cardiovascular disease (CVD. The objective of this study was to determine the efficacy of resveratrol supplementation on serum glucose and CVD risk factors in individuals with SZ. Methods and Results: This is a four-week randomized, double-blind controlled trial (registration No.: NCT 02062190 in which 19 men with a diagnosis of SZ, aged 18 to 65, were assigned to either a resveratrol supplement group (200 mg/day or a placebo group (200 mg/day. In short, we did not observe significant changes after resveratrol supplementation. In the placebo group, we found a significant increase in total cholesterol levels (p = 0.024 and in LDL-cholesterol (p = 0.002, as well as a decrease in body fat percentage (p = 0.038. The placebo group also showed an increase in triglycerides (9.19% and a reduction in HDL-cholesterol (4.88%. In the resveratrol group, triglycerides decreased (7.64%. Conclusion: In summary, oral resveratrol in reasonably low dosages (200 mg daily brought no differences to body weight, waist circumference, glucose, and total cholesterol. It was possible to note that the lipid profile in the placebo group worsened and, although no significant differences were found, we can assume that resveratrol might prevent lipid profile damage and that the intervention affected the lipoprotein metabolism at various levels.

    Full Text Available Sydney B Long, Michael J Blaha, Roger S Blumenthal, Erin D MichosJohns Hopkins Ciccarone Center for the Prevention of Heart Disease, Baltimore, MD, USAAbstract: Age is one of the strongest predictors of cardiovascular disease (CVD risk. Treatment with statins can significantly reduce CVD events and mortality in both primary and secondary prevention. Yet despite the high CVD risk among the elderly, there is underutilization of statins in this population (ie, the treatment-risk paradox. Few studies have investigated the use of statins in the elderly, particularly for primary prevention and, as a result, guidelines for treating the elderly are limited. This is likely due to: uncertainties of risk assessment in older individuals where the predictive value of individual risk factors is decreased; the need to balance the benefits of primary prevention with the risks of polypharmacy, health care costs, and adverse medication effects in a population with decreased life expectancy; the complexity of treating patients with many other comorbidities; and increasingly difficult social and economic concerns. As life expectancy increases and the total elderly population grows, these issues become increasingly important. JUPITER (Justification for the Use of statins in Prevention: an Intervention Trial Evaluating Rosuvastatin is the largest primary prevention statin trial to date and enrolled a substantial number of elderly adults. Among the 5695 JUPITER participants ≥70 years of age, the absolute CVD risk reduction associated with rosuvastatin was actually greater than for younger participants. The implications of this JUPITER subanalysis and the broader role of statins among older adults is the subject of this review.Keywords: JUPITER, rosuvastatin, elderly, risk

    Full Text Available Abstract It is important for patients that treatments for diabetes not increase cardiovascular (CV risk. The objective of this analysis was to examine retrospectively the CV safety of exenatide BID, a GLP-1 receptor agonist approved for treating hyperglycemia in patients with type 2 diabetes not adequately controlled with diet and exercise. Individual participant data was pooled to assess the relative risk (RR of CV events with exenatide BID versus a pooled comparator (PC group treated with either placebo or insulin from 12 controlled, randomized, clinical trials ranging from 12-52 weeks. Mean baseline values for HbA1c (8.33-8.38%, BMI (31.3-31.5 kg/m2, and duration of diabetes (8 y were similar between groups. Trials included patients with histories of microvascular and/or macrovascular disease. Customized primary major adverse CV events (MACE included stroke, myocardial infarction, cardiac mortality, acute coronary syndrome, and revascularization procedures. The Primary MACE RR (0.7; 95% CI 0.38, 1.31, calculated by the Mantel-Haenszel method (stratified by study, suggested that exenatide use (vs. PC did not increase CV risk; this result was consistent across multiple analytic methods. Because the trials were not designed to assess CV outcomes, events were identified retrospectively from a list of preferred terms by physicians blinded to treatment. Other limitations included the low number of CV events, the short duration of trials (≤1 y, and a single active comparator (insulin. The results of these analyses are consistent with those of a recent retrospective analysis of a large insurance database that found that patients treated with exenatide twice daily were less likely to have a CV event than were patients treated with other glucose-lowering therapies.

    To analyze 15 cases of malposition of branch pulmonary arteries (MBPA) for the hospital-based prevalence, clinical information, surgical outcome, imaging findings, associated cardiovascular and airway abnormalities on cardiovascular computed tomography angiography (CCTA). We retrospectively searched for patients with MBPA from our database consisting of patients referred for CCTA due to known or suspected congenital heart disease and also from all patients receiving chest computed tomography (CT) during the same time period. We analyzed the hospital-based prevalence, image findings, associated cardiovascular anomalies, airway compression, and recorded the clinical information and surgical outcome. Our study showed 15 patients with MBPA (hospital-based prevalence: 0.33 % among patients with congenital heart disease and 0.06 % in all patients receiving chest CT or CCTA). Classic type was more common than lesser type (67 % versus 33 %). All patients had associated cardiovascular anomalies, including aortic arch abnormalities (80 %) and secondary airway compression (33 %). Surgery was performed in 67 % of cardiovascular anomalies and 60 % of airway stenoses. MBPA has a hospital-based prevalence of 0.33 % among patients with congenital heart disease and 0.06 % in all patients receiving either chest CT or CCTA. CCTA can delineate the anatomy of MBPA, associated cardiovascular and airway abnormalities for preoperative evaluation. (orig.)

    Full Text Available Introduction. Death from coronary artery disease (CAD has been until recently considered rare in Nigeria. We present a report of a study of CAD with its predisposing cardiovascular (CVD risk factors in South South Nigeria. Methods. We examined the autopsy reports of 747 coroner cases and 41 consecutive clinically diagnosed cases of ischemic heart disease seen in South South Nigeria. Results. CAD was diagnosed in 13 (1.6% of 747 autopsies. They were predominantly males, urban residents, and of high social class with combination of CVD risk factors of hypertension, alcohol use, diabetes mellitus, cigarette smoking, poor physical activities, and obesity. The mean serum cholesterol of the clinical subjects was 4.7±1.57 mmol/L and 5.07±1.94 mmol/L for angina and myocardial infarction, respectively, which was higher than the mean total cholesterol for locality of 3.1 mmol/L. Conclusion. CAD and its risk factors are contributing to mortality and morbidity in South South Nigeria. These risk factors include hypertension, alcohol use, diabetes mellitus, cigarette smoking, poor physical activity, and obesity. Nigerians in this locality with CAD have raised serum lipids.

    Optogenetics is an exciting new technology in which viral gene or cell delivery is used to inscribe light sensitivity in excitable tissue to enable optical control of bioelectric behavior. Initial progress in the fledgling domain of cardiac optogenetics has included in vitro expression of various light-sensitive proteins in cell monolayers and transgenic animals to demonstrate an array of potentially useful applications, including light-based pacing, silencing of spontaneous activity, and spiral wave termination. In parallel to these developments, the cardiac modeling community has developed a versatile computational framework capable of realistically simulating optogenetics in biophysically detailed, patient-specific representations of the human heart, enabling the exploration of potential clinical applications in a predictive virtual platform. Toward the ultimate goal of assessing the feasibility and potential impact of optogenetics-based therapies in cardiovascular medicine, this review provides (1) a detailed synopsis of in vivo, in vitro, and in silico developments in the field and (2) a critical assessment of how existing clinical technology for gene/cell delivery and intra-cardiac illumination could be harnessed to achieve such lofty goals as light-based arrhythmia termination.

    Pitt-Hopkins syndrome is a rare genetic form of severe psychomotor delay, caused by mutations in transcription cell factor-4 gene and characterized by distinctive dysmorphic features and abnormal breathing pattern. The current report describes the polygraphic features of the syndrome's typical breathing pattern in a patient both in wakefulness and in sleep. The control of these breathing alterations is important to prevent the neurological sequelae linked to chronic cerebral hypoxemia in early ages. No data are available on effective treatment options for breathing abnormalities of Pitt-Hopkins syndrome. The authors polygraphically documented a reduction of apneic and hypopneic phenomena, with a significant improvement in saturation values, after the introduction of sodium valproate.

    Computed tomography is currently the method of choice for the diagnostic and staging of lymphomas. Computed tomography enables accurate measurements of both tumor extent and volume and provides information that can be used to plan an appropriate strategy for the treatment. The purpose of the present article is to describe and analyze the chest and abdomen computed tomography and ultrasound findings in HIV-negative patients with lymphoma. Clinical abnormalities, such as the reason the patient sought medical assistance already showing evidence of lymphocytic disease (not yet diagnosed at this point) and the physical examination abnormalities seen on the first consultation were also studied. This study comprised 30 patients: 40% with non-Hodgkin lymphoma, 46,6% with Hodgkin lymphoma, 10% with Burkitt's lymphoma and 3,3% with lymphoblastic lymphoma. (author)

    Cell transplantation is currently gaining a growing interest as a potential new means of improving the prognosis of patients with cardiac failure. The basic assumption is that left ventricular dysfunction is largely due to the loss of a critical number of cardiomyocytes and that it can be partly reversed by implantation of new contractile cells into the postinfarction scars. Primarily for practical reasons, autologous skeletal myoblasts have been the first to undergo clinical trials and now that the feasibility of the procedure is well established, efficacy data are expected from the ongoing randomized studies. Bone marrow stem cells are also generating a great deal of interest, particularly in patients with acute myocardial infarction, and are currently undergoing extensive clinical testing although recent data have raised a cautionary note about the transdifferentiation potential of these cells. While experimental studies and early-phase clinical trials tend to support the concept that cell therapy may enhance cardiac repair, several key issues still need to be addressed including (1) the optimal type of donor cells in relation to the clinical profile of the patients, (2) the mechanism by which cell engraftment improves cardiac function, (3) the optimization of cell survival, (4) the development of less invasive cell delivery techniques and (5) the potential benefits of cell transplantation in nonischemic heart failure. Current evidence suggests, however, that adult stem cells (myogenic or marrow-derived) fail to electromechanically integrate within the recipient heart, thereby mandating the search for second generation cell types able to achieve this goal which is the prerequisite for an effective enhancement of contractile function. Preliminary data suggest that cells that feature a true cardiomyogenic phenotype such as cardiac stem cells and cardiac-precommitted embryonic stem cells may fall in this category and carry the potential for ensuring a true

    Highlights: • Abnormal {sup 18}F-FDG uptakes in the head and neck (HN) region can be carefully interpreted as being index primary, second primary cancer (SP) or benign. • {sup 18}F-FDG PET/CT identified 91.9% primary HN squamous cell carcinomas (HNSCC). • The specificity and negative predictive value of {sup 18}F-FDG PET/CT for identification of SP were as high as 98.7% and 99.3%, respectively. • Proper detection of primary tumors and SP in the HN region may promote appropriate therapeutic planning of HNSCC patients. - Abstract: Purpose: Fluorine 18-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography (PET)/computed tomography (CT) is used to identify index or second primary cancer (SP) of the head and neck (HN) through changes in {sup 18}F-FDG uptake. However, both physiologic and abnormal lesions increase {sup 18}F-FDG uptake. Therefore, we evaluated {sup 18}F-FDG uptake in the HN region to determine clinical values of abnormal tracer uptake. Methods: A prospective study approved by the institutional review board was conducted in 314 patients with newly diagnosed HN squamous cell carcinoma (HNSCC) and informed consent was obtained from all enrolled patients. The patients received initial staging workups including {sup 18}F-FDG PET/CT and biopsies. All lesions with abnormal HN {sup 18}F-FDG uptake were recorded and most of those were confirmed by biopsies. Diagnostic values for abnormal {sup 18}F-FDG uptake were calculated. Results: Abnormal {sup 18}F-FDG uptake was identified in primary tumors from 285 (91.9%) patients. False-negative results were obtained for 22.3% (23/103) T1 tumors and 2.2% (2/93) T2 tumors (P < 0.001). Thirty-eight regions of abnormal {sup 18}F-FDG uptake were identified in 36 (11.5%) patients: the thyroid (n = 13), maxillary sinus (n = 7), palatine tonsil (n = 6), nasopharynx (n = 5), parotid gland (n = 2) and others (n = 5). Synchronous SP of the HN was identified in eight (2.5%) patients: the thyroid (n = 5), palatine

    Full Text Available Abstract Background Our study aimed to investigate both the clinical implications of late gadolinium enhancement (LGE by cardiovascular magnetic resonance (CMR and the relation of LGE to clinical findings in patients with Takotsubo cardiomyopathy (TTC. Methods We evaluated 20 consecutive patients (2 men, 18 women; median age, 77 years; interquartile range [IQR] 67-82 years who were admitted to our hospital with the diagnosis of TTC. CMR was performed within 1 week after admission, and follow-up studies were conducted 1.5 and 6 months later. Results In 8 patients, CMR imaging during the sub-acute phase revealed LGE in the area matched with wall motion impairment. Cardiogenic shock was more frequently observed in patients with LGE than in those without LGE (38% vs 0%, p = 0.049. The patients with LGE needed a longer duration for ECG normalization and recovery of wall motion than did those without LGE (median 205 days, IQR [152-363] vs 68 days, [43-145], p = 0.005; 15 days, [10-185] vs 7 days, [4-13], p = 0.030, respectively. In 5 of these 8 patients, LGE disappeared within 45-180 days (170, IQR [56-180] of onset. The patients with LGE remaining in the chronic phase had higher peak creatine kinase levels than did those without LGE (median 307 IU/L, IQR [264-460] vs 202 IU/L, [120-218], p = 0.017. Conclusion LGE by CMR in the sub-acute phase may be associated with the severity and prolonged recovery to normal of clinical findings in TTC.

    Full Text Available BACKGROUND: D-Serine, an endogenous co-agonist of the N-methyl-D-aspartate (NMDA receptor, is synthesized from L-serine by serine racemase (SRR. Given the role of D-serine in both neurodevelopment and the pathophysiology of schizophrenia, we examined whether neonatal disruption of D-serine synthesis by SRR inhibition could induce behavioral abnormalities relevant to schizophrenia, in later life. METHODOLOGY/PRINCIPAL FINDINGS: Neonatal mice (7-9 days were injected with vehicle or phenazine methosulfate (Met-Phen: 3 mg/kg/day, an SRR inhibitor. Behavioral evaluations, such as spontaneous locomotion, novel object recognition test (NORT, and prepulse inhibition (PPI were performed at juvenile (5-6 weeks old and adult (10-12 weeks old stages. In addition, we tested the effects of D-serine on PPI deficits in adult mice after neonatal Met-Phen exposure. Finally, we assessed whether D-serine could prevent the onset of schizophrenia-like behavior in these mice. Neonatal Met-Phen treatment reduced D-serine levels in the brain, 24 hours after the final dose. Additionally, this treatment caused behavioral abnormalities relevant to prodromal symptoms in juveniles and to schizophrenia in adults. A single dose of D-serine improved PPI deficits in adult mice. Interestingly, chronic administration of D-serine (900 mg/kg/day from P35 to P70 significantly prevented the onset of PPI deficits after neonatal Met-Phen exposure. CONCLUSIONS/SIGNIFICANCE: This study shows that disruption of D-serine synthesis during developmental stages leads to behavioral abnormalities relevant to prodromal symptoms and schizophrenia, in later life. Furthermore, early pharmacological intervention with D-serine may prevent the onset of psychosis in adult.

    Non-alcoholic fatty liver disease (NAFLD) is considered to be an independent cardiovascular disease (CVD) risk factor. However, simple steatosis has a benign clinical course without excess mortality. In contrast, the advanced form of NAFLD, non-alcoholic steatohepatitis (NASH) with liver fibrosis increases mortality by approximately 70%, due to an increase in CVD mortality by approximately 300%. Chronic kidney disease (CKD) may be caused by NAFLD/NASH and it substantially increases CVD risk, especially in the presence of type 2 diabetes mellitus. Moreover, CKD may trigger NAFLD/NASH deterioration in a vicious cycle. NAFLD/NASH is also related to increased arterial stiffness (AS), an independent CVD risk factor that further raises CVD risk. Diagnosis of advanced liver fibrosis (mainly by simple non-invasive tests), CKD, and increased AS should be made early in the course of NAFLD and treated appropriately. Lifestyle measures and statin treatment may help resolve NAFLD/NASH and beneficially affect the CVD risk factors mentioned above.

    LCZ696, a first-in-class angiotensin receptor neprilysin inhibitor (ARNI), is comprised of the angiotensin receptor blocker valsartan and the neprilysin inhibitor pro-drug sacubitril (AHU377). After oral administration, AHU377 is rapidly metabolized to the active neprilysin inhibitor LBQ657. LCZ696 exerts its effects of diuresis, natriuresis, vasodilation and aldosterone secretion inhibition through simultaneous renin-angiotensin-aldosterone system (RAAS) blockade and natriuretic peptides system (NPS) enhancement. Powerful evidence including PARAMETER and PRARDIGM-HF trials have shown that LCZ696 outperforms RAAS inhibition in treating patients with hypertension and heart failure with reduced ejection fraction (HFrEF), and is well tolerated. In addition, accumulating evidence also suggests its potential use in heart failure with preserved ejection fraction (HFpEF), chronic kidney disease (CKD), post-myocardium infarction (post-MI) and stroke. Both the FDA and CHMP have approved LCZ696 for treatment of HFrEF. Despite all this, some special issues (e.g. use in specific subgroups, adverse events, contraindications and cost-effectiveness analysis) should be considered before its implementation in clinical practice.

    Full Text Available Cardiovascular disease is the leading cause of mortality after renal transplantation. The purpose of this study was to analyze cardiovascular risk factors at transplantation, occurrence of cardiovascular events in the first year after transplantation and evaluate pre-transplant work-up.In total, 244 renal transplant recipients older than 50 years were included. The results of pre-transplant work-up, including clinical evaluation, electrocardiogram, echocardiography, myocardial perfusion testing and coronary angiography were analyzed.Patients had multiple risk factors at inclusion on renal transplantation waiting list as high blood pressure (94.7%, dyslipidemia (81.1%, smoking (45.3%, diabetes (23.6%, past history of cardiovascular disease (21.3% and obesity (12.7%. Following transplantation, 15.5% (n = 38 of patients experienced a cardiovascular event, including 2.8% (n = 7 acute coronary syndrome, 5.8% (n = 14 isolated increase in troponin level and 5.3% (n = 13 new onset atrial fibrillation. The pre-transplant parameters associated with a cardiovascular event were a past medical history of cardiovascular disease (HR = 2.06 [1.06-4.03], p = 0.03, echocardiographic left ventricular hypertrophy (HR = 2.04 [1.04-3.98], p = 0.037 and abnormal myocardial perfusion testing (HR = 2.25 [1.09 -5.96], p = 0.03. Pre-transplantation evaluation allowed the diagnosis of unknown coronary artery lesions in 8.9% of patients.

    Full Text Available Abstract Background Liver function tests (LFTs are routinely performed in primary care, and are often the gateway to further invasive and/or expensive investigations. Little is known of the consequences in people with an initial abnormal liver function (ALF test in primary care and with no obvious liver disease. Further investigations may be dangerous for the patient and expensive for Health Services. The aims of this study are to determine the natural history of abnormalities in LFTs before overt liver disease presents in the population and identify those who require minimal further investigations with the potential for reduction in NHS costs. Methods/Design A population-based retrospective cohort study will follow up all those who have had an incident liver function test (LFT in primary care to subsequent liver disease or mortality over a period of 15 years (approx. 2.3 million tests in 99,000 people. The study is set in Primary Care in the region of Tayside, Scotland (pop approx. 429,000 between 1989 and 2003. The target population consists of patients with no recorded clinical signs or symptoms of liver disease and registered with a GP. The health technologies being assessed are LFTs, viral and auto-antibody tests, ultrasound, CT, MRI and liver biopsy. The study will utilise the Epidemiology of Liver Disease In Tayside (ELDIT database to determine the outcomes of liver disease. These are based on hospital admission data (Scottish Morbidity Record 1, dispensed medication records, death certificates, and examination of medical records from Tayside hospitals. A sample of patients (n = 150 with recent initial ALF tests or invitation to biopsy will complete questionnaires to obtain quality of life data and anxiety measures. Cost-effectiveness and cost utility Markov model analyses will be performed from health service and patient perspectives using standard NHS costs. The findings will also be used to develop a computerised clinical decision

    Full Text Available The objective of the present study was to evaluate the reliability and clinical utility of a Portuguese version of the Abnormal Involuntary Movements Scale (AIMS. Videotaped interviews with 16 psychiatric inpatients treated with antipsychotic drugs for at least 5 years were evaluated. Reliability was assessed by the intraclass correlation coefficient (ICC between three raters, two with and one without clinical training in psychopathology. Clinical utility was assessed by the difference between the scores of patients with (N = 11 and without (N = 5 tardive dyskinesia (TD. Patients with TD exhibited a higher severity of global evaluation by the AIMS (sum of scores: 4.2 ± 0.9 vs 0.4 ± 0.2; score on item 8: 2.3 ± 0.3 vs 0.4 ± 0.2, TD vs controls. The ICC for the global evaluation was fair between the two skilled raters (0.58-0.62 and poor between these raters and the rater without clinical experience (0.05-0.29. Thus, we concluded that the Portuguese version of the AIMS shows an acceptable inter-rater reliability, but only between clinically skilled raters, and that it is clinically useful.

    Full Text Available Abstract Background Physicians involved in primary prevention are key players in CVD risk control strategies, but the expected reduction in CVD risk that would be obtained if all patients attending primary care had their risk factors controlled according to current guidelines is unknown. The objective of this study was to estimate the excess risk attributable, firstly, to the presence of CVD risk factors and, secondly, to the lack of control of these risk factors in primary prevention care across Europe. Methods Cross-sectional study using data from the European Study on Cardiovascular Risk Prevention and Management in Daily Practice (EURIKA, which involved primary care and outpatient clinics involved in primary prevention from 12 European countries between May 2009 and January 2010. We enrolled 7,434 patients over 50 years old with at least one cardiovascular risk factor but without CVD and calculated their 10-year risk of CVD death according to the SCORE equation, modified to take diabetes risk into account. Results The average 10-year risk of CVD death in study participants (N = 7,434 was 8.2%. Hypertension, hyperlipidemia, smoking, and diabetes were responsible for 32.7 (95% confidence interval 32.0-33.4, 15.1 (14.8-15.4, 10.4 (9.9-11.0, and 16.4% (15.6-17.2 of CVD risk, respectively. The four risk factors accounted for 57.7% (57.0-58.4 of CVD risk, representing a 10-year excess risk of CVD death of 5.66% (5.47-5.85. Lack of control of hypertension, hyperlipidemia, smoking, and diabetes were responsible for 8.8 (8.3-9.3, 10.6 (10.3-10.9, 10.4 (9.9-11.0, and 3.1% (2.8-3.4 of CVD risk, respectively. Lack of control of the four risk factors accounted for 29.2% (28.5-29.8 of CVD risk, representing a 10-year excess risk of CVD death of 3.12% (2.97-3.27. Conclusions Lack of control of CVD risk factors was responsible for almost 30% of the risk of CVD death among patients participating in the EURIKA Study.

    Full Text Available Objective: Alcohol is most commonly abused drug worldwide. It has been shown to produce toxic effects in almost every organ system in the body. Many of these medical conditions can be attributed to direct effects of alcohol whereas others are indirect sequelae that may result from nutritional deficiencies or predisposition to trauma. Alcohol consumption has been associated with a variety of cardio vascular disorders this study was thus undertaken to know the Electrocardiographic and Echocardiographic abnormalities in asymptomatic chronic alcoholic patients. Materials and Methods: 50 Patients attending the out-patient clinic & who were admitted in Al Ameen Medical College Hospital and District hospital, Bijapur were selected for the study. It was a prospective study design subjects in age group 20-40, having history of chronic alcoholism as defined, for more than 5 years were evaluated by electrocardiography and echocardiography. Patients with known diabetics, hypertensive and cardiovascular disorders were excluded from the study group. Results: The prevalence of cardiovascular abnormalities in patients of chronic alcoholism is 37% in our study. Most common ECG changes are sinus tachycardia (18%, and Non specific ST-T changes (9%. Most common 2D ECHO changes was increased posterior wall thickness (11% and followed by increased interventricular septum thickness and decreased ejection fraction (<40%. The prevalence of cardio vascular abnormalities are more with increased duration of alcohol consumption and also high in advanced age group. Conclusions: This study confirms that many electrocardiographic as well as echocardiographic changes occur prior to symptomatic cardiac disorders established to be caused by chronic alcohol intake such as alcoholic cardiomyopathy .which probably are early indictors of ongoing effects of alcohol and are reversible during the early stages detected by non invasive investigations like Electrocardiography and

    The Cancer Genome Atlas Network recently cataloged recurrent genomic abnormalities in glioblastoma multiforme (GBM). We describe a robust gene expression-based molecular classification of GBM into Proneural, Neural, Classical, and Mesenchymal subtypes and integrate multidimensional genomic data to establish patterns of somatic mutations and DNA copy number. Aberrations and gene expression of EGFR, NF1, and PDGFRA/IDH1 each define the Classical, Mesenchymal, and Proneural subtypes, respectively. Gene signatures of normal brain cell types show a strong relationship between subtypes and different neural lineages. Additionally, response to aggressive therapy differs by subtype, with the greatest benefit in the Classical subtype and no benefit in the Proneural subtype. We provide a framework that unifies transcriptomic and genomic dimensions for GBM molecular stratification with important implications for future studies.

    Drug-induced liver chemistry abnormalities, primarily transaminase elevations, are commonly observed in pazopanib-treated patients. This meta-analysis characterises liver chemistry abnormalities associated with pazopanib. Data of pazopanib-treated patients from nine prospective trials were integrated (N=2080). Laboratory datasets were used to characterise the incidence, timing, recovery and patterns of liver events, and subsequent rechallenge with pazopanib. Severe cases of liver chemistry abnormalities were clinically reviewed. Multivariate analyses identified predisposing factors. Twenty percent of patients developed elevated alanine aminotransferase (ALT) >3×ULN. Incidence of peak ALT >3-5×ULN, >5-8×ULN, >8-20×ULN and >20×ULN was 8%, 5%, 5% and 1%, respectively. Median time to onset for all events was 42days; 91% of events were observed within 18weeks. Recovery rates based on peak ALT >3-5×ULN, >5-8×ULN, >8-20×ULN and >20×ULN were 91%, 90%, 90% and 64%, respectively. Median time from onset to recovery was 30days, but longer in patients without dose interruption. Based on clinical review, no deaths were associated with drug-induced liver injury. Overall, 38% of rechallenged patients had ALT elevation recurrence, with 9-day median time to recurrence. Multivariate analysis showed that older age was associated with development of ALT >8×ULN. There was no correlation between hypertension and transaminitis. Our data support the current guidelines on regular liver chemistry tests after initiation of pazopanib, especially during the first 9 or 10weeks, and also demonstrate the safety of rechallenge with pazopanib.

    Full Text Available The 2001 Bethesda system recommends further classifying atypical glandular cells (AGCs as either endocervical or endometrial origin. Numerous studies have investigated the clinical significance of AGC. In this study, we investigated the incidence of clinically significant lesions among women with liquid-based Papanicolaou cervicovaginal (Pap interpretations of atypical endometrial cells (AEMs or AGC favor endometrial origin (AGC-EM. More importantly, we correlated patients of AEM or AGC-EM with their clinical presentations to determine if AEM/AGC-EM combined with abnormal vaginal bleeding is associated with a higher incidence of significant endometrial pathology. All liquid-based Pap tests with an interpretation of AEM and AGC-EM from July, 2004 through June, 2009 were retrieved from the database. Women with an interpretation of atypical endocervical cells, AGC, favor endocervical origin or AGC, favor neoplastic were not included in the study. The most severe subsequent histologic diagnoses were recorded for each patient. During this 5-year period, we accessioned 332,470 Pap tests of which 169 (0.05% were interpreted as either AEM or AGC-EM. Of the 169 patients, 133 had histologic follow-up within the health care system. The patients ranged in age from 21 to 71 years old (mean 49.7. On follow-up histology, 27 (20.3% had neoplastic/preneoplastic uterine lesions. Among them, 20 patients were diagnosed with adenocarcinoma (18 endometrial, 1 endocervical, and 1 metastatic colorectal, 3 with atypical endometrial hyperplasia, and 4 with endometrial hyperplasia without atypia. All patients with significant endometrial pathology, except one, were over 40 years old, and 22 of 25 patients reported abnormal vaginal bleeding at the time of endometrial biopsy or curettage. This study represents a large series of women with liquid-based Pap test interpretations of AEM and AGC-EM with clinical follow-up. Significant preneoplastic or neoplastic endometrial

    Objectif : Les femmes qui en viennent à connaître une prééclampsie pendant la grossesse sont exposées à un risque élevé d’en venir par la suite à présenter des maladies chroniques, dont la maladie cardiovasculaire prématurée. Nous avons mis sur pied une clinique interdisciplinaire qui vise à prévenir la maladie cardiovasculaire par l’offre de services de counseling pédagogique axés sur les modifications à apporter au mode de vie aux débuts de la période postpartum. Cette étude avait pour objectif d’évaluer les modifications du poids et des facteurs de risque cardiovasculaire chez les participantes, après six mois de consultations à la clinique. Méthodes : Nous avons mené une analyse rétrospective des dossiers des femmes dont la grossesse avait été compliquée par la prééclampsie et qui avaient par la suite fréquenté la Postpartum Preeclampsia Clinic. Pour déterminer les paramètres de départ, les participantes à l’étude ont été soumises à des évaluations du mode de vie, à des examens physiques et à des analyses de laboratoire. Des objectifs personnalisés en matière de réduction du risque cardiovasculaire et de modification du mode de vie ont été établis, le tout étant axé sur l’activité physique et les modifications du régime alimentaire. La modification du poids constituait le critère d’évaluation principal. Résultats : Au cours de la période d’étude, 21 femmes ont fait l’objet d’un suivi d’une durée minimale de six mois. À 4,4 ± 1,4 mois postpartum en moyenne (± σ), les participantes présentaient une amélioration non significative en matière de poids (perte pondérale moyenne de 0,4 ± 4,5 kg) et d’IMC (diminution moyenne de l’IMC de 0,1 ± 1,7 kg/m2). Le niveau d’activité physique a connu une amélioration significative, passant de 14 % des participantes pratiquant des activités physiques avant la grossesse à 76 % après 4,4 mois postpartum en moyenne

    Full Text Available OBJECTIVE - To evaluate the cardiac abnormalities and their evolution during the course of the acquired immunodeficiency syndrome, as well as to correlate clinical and pathological data. METHODS - Twenty-one patients, admitted to the hospital with the diagnosis of acquired immunodeficiency syndrome, were prospectively studied and followed until their death. Age ranged from 19 to 42 years (17 males. ECG and echocardiogram were also obtained every six months. After death, macro- and microscopic examinations were also performed. RESULTS - The most frequent causes of referral to the hospital were: diarrhea or repeated pneumonias, tuberculosis, toxoplasmosis or Kaposi sarcoma. The most frequent findings were acute or chronic pericarditis (42% and dilated cardiomyopathy (19%. Four patients died of cardiac problems: infective endocarditis, pericarditis with pericardial effusion, bacterial myocarditis and infection by Toxoplasma gondii. CONCLUSION - Severe cardiac abnormalities were the cause of death in some patients. In the majority of the patients, a good correlation existed between clinical and anatomical-pathological data. Cardiac evaluation was important to detect early manifestations and treat them accordingly, even in asymptomatic patients.

  10. A literature review on cardiovascular risk in human immunodeficiency virus-infected patients: implications for clinical management

    Full Text Available INTRODUCTION: In recent years, there has been growing concern about an increasing rate of cardiovascular diseases in human immunodeficiency virus-infected patients, which could be associated with side effects of highly active antiretroviral therapy. It is likely that the metabolic disorders related to anti-human immunodeficiency virus treatment will eventually translate into a increased cardiovascular risk in patients submitted to such regimens. OBJECTIVE: To evaluate if human immunodeficiency virus-infected patients receiving highly active antiretroviral therapy are at higher risk of cardiovascular diseases than human immunodeficiency virus infected patients not receiving highly active antiretroviral therapy, or the general population. RESEARCH DESIGN AND METHODS: We conducted a computer-based search in representative databases, and also performed manual tracking of citations in selected articles. RESULT: The available evidence suggests an excess risk of cardiovascular events in human immunodeficiency virus-infected persons compared to non-human immunodeficiency virus infected individuals. The use of highly active antiretroviral therapy is associated with increased levels of total cholesterol, triglycerides, low-density lipoprotein and morphological signs of cardiovascular diseases. Some evidence suggested that human immunodeficiency virus-infected individuals on highly active antiretroviral therapy regimens are at increased risk of dyslipidemia, ischemic heart disease, and myocardial infarction, particularly if the highly active antiretroviral therapy regimen contains a protease inhibitor. CONCLUSION: Physicians must weigh the cardiovascular risk against potential benefits when prescribing highly active antiretroviral therapy. Careful cardiac screening is warranted for patients who are being evaluated for, or who are receiving highly active antiretroviral therapy regimens, particularly for those with known underlying cardiovascular risk

    The aim of the study is to determine the inter-reliability and intra-observer reliability of magnetic resonance imaging (MRI) for lateral epicondylitis and investigate whether there is a potential relationship between MRI abnormalities of the common extensor tendon (CET) and its clinical symptom.The study group comprised 96 consecutive patients (46 men and 50 women) with a clinical diagnosis of chronic lateral epicondylitis, which were examined on 3.0 T MR. An MRI scoring system was used to grade the degree of tendinopahty. Three independent musculoskeletal radiologists, who were blinded to the patients' clinical information, scored images separately. Clinical symptoms were assessed using the Patient-Rated Tennis Elbow Evaluation (PRTEE).Of all the patients, total 96 elbows had MRI-assessed tendinopathy, including 38 (39.6%) with grade 1, 31 (32.3%) with grade 2, and 27 (28.1%) with grade 3. Inter-observer reliability and intra-observer agreement for MRI interpretation of the grades of tendinopathy was good, and a positive correlation between the grades of tendinopathy and PRTEE was determined.MRI is a reliable tool in determining radiological severity of chronical lateral epicondylitis. The severity of MR signal changes positively correlate with the patient's clinical symptom.

To study the conformity of preventative therapy prescribed to patients during a hospital stay and at a discharge to clinical guidelines using a special algorithm, and to assess the impact of the results on a long-term mortality based on the LIS-2 register (Lyubertsy study of mortality in patients after cerebral stroke.Material and methods. The scales to assess the quality of cardiovascular care for the prevention of recurrent stroke along with the prevention of recurrent ischemic attacks index (PRIA index for this assessment were developed according to current clinical guidelines. Analysis of the therapy was performed using PRIA index on survived hospital patients from LIS-2 register (N=753. The impact of PRIA index results on a long-term mortality (Me=2.3 years was studied.Results. Based upon the results of the assessment obtained with PRIA index, higher treatment conformity to clinical guidelines resulted in a significantly better long-term survival. Non-conformity to clinical guidelines was due to the lack of prescription of drugs with proven efficacy and irrational choice of preventive therapy. Median of treatment quality assessment was 44.4% (22.2; 44.4.Conclusion. Low conformity of preventive therapy to clinical guidelines is found in the LIS-2 register. The algorithm for the assessment of preventive cardiovascular therapy quality allows identifying limitations in the prevention of recurrent stroke, and can serve as an example of implementation of evidence-based medicine in clinical practice.

    Although it has been recognized for a long time that the predisposition to cardiovascular diseases (CVD) is determined by many risk factors and despite the common use of algorithms incorporating several of these factors to predict the overall risk, there has yet been no global description of the complex way in which CVD risk factors interact with each other. This is the aim of the present study which investigated all existing relationships between the main CVD risk factors in a well-characterized occupational cohort. Prospective associations between 12 behavioural and clinical risk factors (gender, age, parental history of CVD, non-moderate alcohol consumption, smoking, physical inactivity, obesity, hypertension, dyslipidemia, diabetes, sleep disorder, depression) were systematically tested using Cox regression in 10,736 middle-aged individuals free of CVD at baseline and followed over 20 years. In addition to independently predicting CVD risk (HRs from 1.18 to 1.97 in multivariable models), these factors form a vast network of associations where each factor predicts, and/or is predicted by, several other factors (n = 47 with p<0.05, n = 37 with p<0.01, n = 28 with p<0.001, n = 22 with p<0.0001). Both the number of factors associated with a given factor (1 to 9) and the strength of the associations (HRs from 1.10 to 6.12 in multivariable models) are very variable, suggesting that all the factors do not have the same influence within this network. These results show that there is a remarkably extensive network of relationships between the main CVD risk factors which may have not been sufficiently taken into account, notably in preventive strategies aiming to lower CVD risk.

    A phase abnormality in radionuclide multigated studies (MUGA) in patients with tricuspid regurge (TR) is being described. In this condition of TR, as the right ventricle contracts, if causes the blood to regurge through the tricuspid valve to the right atrium and through the inferior Vena cava and hepatic veins to the adjacent liver tissue. As a result the right atrium and the liver will be in the same delayed phase forming a Crescent to the right side of the heart representing the right atrium and extending below the heart into the region of the liver. This Crescent has been graded according to how far it is extending in the liver and below the heart. In 15 patients with cardiac cath finding of TR (done within 2-3 days of the MUGA study), the phase displays of the radionuclide MUGA studies were analysed in order to find out the sensitivity of the Crescent Sign in the detection of TR and whether there is a relationship between the grade of the Crescent and the severity of the regurgitation. The Crescent was found in 13 of the 15 patients (sensitivity = 87%). We have not found a correlation between the severity of TR and the grade of the Crescent. We conclude that the presence of the Crescent Sign in phase display of the MUGA study should direct the attention of the clinician towards the recognition of TR, a condition which is sometimes difficult to diagnose non-invasively.

    Abstract Objective: to evaluate the effect and gender differences of an innovative intervention involving in-person and telephone nursing counseling to control cardiovascular risk factors (arterial hypertension, dyslipidemia, and overweight), improve health-related quality of life and strengthen self-efficacy and social support in persons using the municipal health centers' cardiovascular health program. Method: a randomized controlled clinical trial involving participants randomized into the intervention group who received traditional consultation plus personalized and telephone nursing counseling for 7 months (n = 53) and the control group (n = 56). The study followed the Consolidated Standards of Reporting Trials Statement. Results: women in the intervention group presented a significant increase in the physical and mental health components compared to the control group, with decreases in weight, abdominal circumference, total cholesterol, low-density lipoprotein cholesterol, and the atherogenic index. The effects attributable to the intervention in the men in the intervention group were increased physical and emotional roles and decreased systolic and diastolic pressure, waist circumference, total cholesterol, low-density lipoprotein cholesterol, atherogenic index, cardiovascular risk factor, and 10-year coronary risk. Conclusion: this intervention is an effective strategy for the control of three cardiovascular risk factors and the improvement of health-related quality of life. PMID:27508917

    Conclusion: In patients with DM1, the combined smaller overall gray matter volume and white matter alterations seem to be the main morpho-structural substrates of CNS involvement in this condition. The correlation of white matter differences with both clinical and genetic findings lends support to this notion.

    Sports-related concussions have been shown to lead to persistent subclinical anomalies of the motor and cognitive systems in young asymptomatic athletes. In advancing age, these latent alterations correlate with detectable motor and cognitive function decline. Until now, the interacting effects of concussions and the normal ageing process on white matter tract integrity remain unknown. Here we used a tract-based spatial statistical method to uncover potential white matter tissue damage in 15 retired athletes with a history of concussions, free of comorbid medical conditions. We also investigated potential associations between white matter integrity and declines in cognitive and motor functions. Compared to an age- and education-matched control group of 15 retired athletes without concussions, former athletes with concussions exhibited widespread white matter anomalies along many major association, interhemispheric, and projection tracts. Group contrasts revealed decreases in fractional anisotropy, as well as increases in mean and radial diffusivity measures in the concussed group. These differences were primarily apparent in fronto-parietal networks as well as in the frontal aspect of the corpus callosum. The white matter anomalies uncovered in concussed athletes were significantly associated with a decline in episodic memory and lateral ventricle expansion. Finally, the expected association between frontal white matter integrity and motor learning found in former non-concussed athletes was absent in concussed participants. Together, these results show that advancing age in retired athletes presenting with a history of sports-related concussions is linked to diffuse white matter abnormalities that are consistent with the effects of traumatic axonal injury and exacerbated demyelination. These changes in white matter integrity might explain the cognitive and motor function declines documented in this population.

    The European Commission announced in 2008 that a fundamental revision of the medical device directives is being considered in order to clarify and strengthen the current legal framework. The system for testing and approving devices in Europe was established >20 years ago as a 'New Approach' to a previously little-regulated industry. It is recognized by many that the regulatory system has not kept pace with technological advances and changing patterns of medical practice. New legislation will be drafted during 2011, but medical experts have been little involved in this important process. This context makes it an opportune time for a professional association to advise from both clinical and academic perspectives about changes which should be made to improve the safety and efficacy of devices used in clinical practice and to develop more appropriate systems for their clinical evaluation and post-marketing surveillance. This report summarizes how medical devices are regulated and it reviews some serious clinical problems that have occurred with cardiovascular devices. Finally, it presents the main recommendations from a Policy Conference on the Clinical Evaluation of Cardiovascular Devices that was held at the European Heart House in January 2011.

    The aim of this study was to evaluate the long-term clinical significance of an additional chromosomal abnormality (ACA), variant Philadelphia chromosome (vPh) at diagnosis, and newly developed other chromosomal abnormalities (OCA) in patients with chronic myeloid leukemia (CML) on imatinib (IM) therapy. Sequential cytogenetic data from 281 consecutive new chronic phase CML patients were analyzed. With a median follow-up of 78.6 months, the 22 patients with vPh (P = 0.034) or ACA (P = 0.034) at diagnosis had more events of IM failure than did the patients with a standard Ph. The 5-year overall survival (OS), event-free survival (EFS), and failure-free survival (FFS) rates for patients with vPh at diagnosis were 77.8%, 75.0%, and 53.3%, respectively; for patients with ACA at diagnosis, 100%, 66.3%, and 52.1%, respectively; and for patients with a standard Ph, 96.0%, 91.3%, and 83.7%, respectively. During IM therapy, eight patients developed an OCA, which had no impact on outcomes as a time-dependent covariate in our Cox proportional hazards regression models. This study showed that vPh was associated with poor OS and FFS and that ACA had adverse effects on EFS and FFS. In addition, no OCA, except monosomy 7, had any prognostic impact, suggesting that the development of OCA may not require a change in treatment strategy.

  7. Abnormalities of gonadal differentiation.

    Gonadal differentiation involves a complex interplay of developmental pathways. The sex determining region Y (SRY) gene plays a key role in testis determination, but its interaction with other genes is less well understood. Abnormalities of gonadal differentiation result in a range of clinical problems. 46,XY complete gonadal dysgenesis is defined by an absence of testis determination. Subjects have female external genitalia and come to clinical attention because of delayed puberty. Individuals with 46,XY partial gonadal dysgenesis usually present in the newborn period for the valuation of ambiguous genitalia. Gonadal histology always shows an abnormality of seminiferous tubule formation. A diagnosis of 46,XY true hermaphroditism is made if the gonads contain well-formed testicular and ovarian elements. Despite the pivotal role of the SRY gene in testis development, mutations of SRY are unusual in subjects with a 46,XY karyotype and abnormal gonadal development. 46,XX maleness is defined by testis determination in an individual with a 46,XX karyotype. Most affected individuals have a phenotype similar to that of Klinefelter syndrome. In contrast, subjects with 46,XX true hermaphroditism usually present with ambiguous genitalia. The majority of subjects with 46,XX maleness have Y sequences including SRY in genomic DNA. However, only rare subjects with 46,XX true hermaphroditism have translocated sequences encoding SRY. Mosaicism and chimaerism involving the Y chromosome can also be associated with abnormal gonadal development. However, the vast majority of subjects with 45,X/46,XY mosaicism have normal testes and normal male external genitalia.

    The clinical conditions associated with GH excess and GH deficiency (GHD) are known to be associated with an increased risk for the cardiovascular morbidity and mortality, suggesting that either an excess or a deficiency in GH and/or IGF-I is deleterious for cardiovascular system. In patients with acromegaly, chronic GH and IGF-I excess commonly causes a specific cardiomyopathy characterized by a concentric cardiac hypertrophy associated with diastolic dysfunction and, in later stages, with systolic dysfunction ending in heart failure if GH/IGF-I excess is not controlled. Abnormalities of cardiac rhythm and anomalies of cardiac valves can also occur. Moreover, the increased prevalence of cardiovascular risk factors, such as hypertension, diabetes mellitus, and insulin resistance, as well as dyslipidemia, confer an increased risk for vascular atherosclerosis. Successful control of the disease is accompanied by a decrease of the cardiac mass and improvement of cardiac function and an improvement in cardiovascular risk factors. In patients with hypopituitarism, GHD has been considered the under- lying factor of the increased mortality when appropriate standard replacement of the pituitary hormones deficiencies is given. Either childhood-onset or adulthood-onset GHD are characterized by a cluster of abnormalities associated with an increased cardiovascular risk, including altered body composition, unfavorable lipid profile, insulin resistance, endothelial dysfunction and vascular atherosclerosis, a decrease in cardiac mass together with an impairment of systolic function mainly after exercise. Treatment with recombinant GH in patients with GHD is followed by an improvement of the cardiovascular risk factors and an increase in cardiac mass together with an improvement in cardiac performance. In conclusion, acromegaly and GHD are associated with an increased risk for cardiovascular morbidity and mortality, but the control of GH/IGF-I secretion reverses cardiovascular

    Systemic lupus erythematosus (SLE) is a well-known cardiovascular risk factor. Less is known about cutaneous lupus erythematosus (CLE) and the risk of developing cardiovascular disease (CVD). Therefore, we investigated the risk of mortality and adverse cardiovascular events in patients diagnosed with SLE and CLE. We conducted a cohort study of the entire Danish population aged ≥ 18 and ≤ 100 years, followed from 1997 to 2011 by individual-level linkage of nationwide registries. Multivariable adjusted Cox regression models were used to estimate the hazard ratios (HRs) for a composite cardiovascular endpoint and all-cause mortality, for patients with SLE and CLE. A total of 3282 patients with CLE and 3747 patients with SLE were identified and compared with 5,513,739 controls. The overall HR for the composite CVD endpoint was 1.31 (95% CI 1.16-1.49) for CLE and 2.05 (95% CI 1.15-3.44) for SLE. The corresponding HRs for all-cause mortality were 1.32 (95% CI 1.20-1.45) for CLE and 2.21 (95% CI 2.03-2.41) for SLE. CLE and SLE were associated with a significantly increased risk of CVD and all-cause mortality. Local and chronic inflammation may be the driver of low-grade systemic inflammation.

    The aim of this study was to investigate the influence of the Multiwave Locked System (MLS) laser therapy on clinical features, microvascular changes in nailfold videocapillaroscopy (NVC) and circulating modulators releasing as a consequence of vascular endothelium injury such as vascular endothelial growth factor (VEGF) and angiopoietin 2 (Ang-2) in patients with primary and secondary Raynaud's phenomenon. Seventy-eight RP patients and 30 healthy volunteers were recruited into the study. All patients with RP received MLS laser irradiation for 3 weeks. Clinical, NVC and laboratory investigations were performed before and after the MLS laser therapy. The serum concentration of VEGF and Ang-2 were determined by an enzyme-linked immunosorbent assay (ELISA). After 3 weeks of MLS laser therapy, the clinical improvement manifested by decreasing of the number of RP attacks, mean duration of Raynaud's attack and pain intensity in RP patients was observed. After MLS laser therapy in 65% of patients with primary and in 35% with secondary RP, an increase in the loop number and/or a reduction in avascular areas in NVC were observed. In comparison with a control group, higher serum concentration of VEGF and Ang-2 in RP patients was demonstrated. After MLS laser therapy, a reduction of Ang-2 in both groups of RP patients was found. Our results suggest that NVC may reflect microvascular changes associated with clinical improvement after MLS laser therapy in patients with primary and secondary RP. Ang-2 serum levels may be a useful marker of microvascular abnormalities in RP patients treated with MLS laser therapy.

    Randomized clinical trials have not shown an additional clinical benefit of renal artery stent placement over optimal medical therapy alone. However, studies of renal artery stent placement have not examined the relationship of albuminuria and treatment group outcomes. The CORAL study (Cardiovascular Outcomes in Renal Atherosclerotic Lesions) is a prospective clinical trial of 947 participants with atherosclerotic renal artery stenosis randomized to optimal medical therapy with or without renal artery stent which showed no treatment differences (3(5.8% and 35.1% event rate at mean 43-month follow-up). In a post hoc analysis, the study population was stratified by the median baseline urine albumin/creatinine ratio (n=826) and analyzed for the 5-year incidence of the primary end point (myocardial infarction, hospitalization for congestive heart failure, stroke, renal replacement therapy, progressive renal insufficiency, or cardiovascular disease- or kidney disease-related death), for each component of the primary end point, and overall survival. When baseline urine albumin/creatinine ratio was ≤ median (22.5 mg/g, n=413), renal artery stenting was associated with significantly better event-free survival from the primary composite end point (73% versus 59% at 5 years; P=0.02), cardiovascular disease-related death (93% versus 85%; P≤ 0.01), progressive renal insufficiency (91% versus 77%; P=0.03), and overall survival (89% versus 76%; P≤0.01), but not when baseline urine albumin/creatinine ratio was greater than median (n=413). These data suggest that low albuminuria may indicate a potentially large subgroup of those with renal artery stenosis that could experience improved event-free and overall-survival after renal artery stent placement plus optimal medical therapy compared with optimal medical therapy alone. Further research is needed to confirm these preliminary observations.

    Objective: Angiogennesis, the formation of new blood vessels from the existing vascular bed, is essential step for growth and invasion of primary tumor. Vascular endothelial growth-factor (VEGF) is known to play crucial role in tumor angiogenesis. In the present study, we investigate the expression of VEGF and VEGF-mRNA in the angiogennesis, metastasis and prognosis of lung cancer.Methods: The VEGF cellular distributions and expression in 38 specimens of patients with lung cancer were investigated with immunohistochemistry stain technology. The total RNAs in 38 tissues of lung cancer was measured, then the levels of VEGF-mRNA expression were analyzed by a reverse-transcription polymerase chain reaction (RT-PCR) assay. The levels of VEGF in sera of patients with lung cancer, benign lung diseases and healthy controls were detected through Enzyme linked immunosorbent assay (ELISA) method. Results: The VEGF positive stain was 76% in 38 cases of lung cancer specimens. The 89% rate of VEGF stain was found for clinical stage Ⅲ cases and 92%for stage Ⅳ lung cancers. The significantly higher expression of VEGF was evidenced in patients with lymph node metastasis (84 % ), distant metastasis (90%), and lung cancers with lower histological differentiation (89%), respectively. The expression level of total RNA was significantly higher in patients with lung cancers than that in their paracancerous or distant lung tissues. The VEGF expressions were tightly correlated with total RNA concentration of lung carcinoma ( P < 0.01 ). The predominant expressions of VEGF121 and VEGF165 gene fragments were found in lung cancer specimens by RT-PCR analysis. No significant difference of serum VEGF levels was detected between cases with lung cancer and patients with benign diseases. However, the VEGF level of cases with benign diseases was decreased significantly after patients with anti-inflammation medication. Conclusion: The present data suggested that the tumor tissue VEGF

    Full Text Available Of the many risk factors suggested for sudden unexpected death in epilepsy (SUDEP, higher frequency of seizures is a very consistent issue. Following this reasoning, it has been established that hemodialysis-associated seizure is a complication of dialysis procedure. Based on these facts, this study investigated a possible association between cardiovascular abnormalities and SUDEP among patients with chronic renal insufficiency in regular hemodialysis program. For that, a retrospective medical history of 209 patients was reviewed to investigate the occurrence of convulsive seizures and EKG abnormalities during dialytic program. Three patients presented generalized tonic-clonic seizures, one had partial seizure with secondary generalization, and one presented unclassified seizure. Any EKG abnormalities and SUDEP event were found in all patients evaluated. In conclusion, the present findings demonstrated uncommon the occurrence of seizures and also SUDEP. Probably, the main justification to not allow us to demonstrated a direct relation between SUDEP and cardiovascular diseases in hemodialysis are the reduced number of cases examined.Um dos principais fatores de risco para a morte súbita e inesperada na epilepsia (SUDEP é a alta freqüência de crises epilépticas. Seguindo este raciocínio, tem sido estabelecido que as crises epilépticas associadas à hemodiálise seja uma complicação do procedimento dialítico. Baseado neste fato, este estudo investigou uma possível associação entre anormalidades cardiovasculares e SUDEP nos pacientes com insuficiência renal crônica em um programa regular de hemodiálise. Para isto, um histórico médico retrospectivo de 209 pacientes foi revisado para avaliar a ocorrência de crises epilépticas e possíveis anormalidades no ECG durante o programa de diálise. Três pacientes apresentaram crises tônico-clonica generalizadas, um apresentou crise parcial com generalização secundária e um apresentou

    Full Text Available Adipose tissue is known to secrete hormones actively and produces many biologically active proteins called adipocytokines. Typically, obesity is followed by low-grade inflammation, which is characterized by increased circulating levels of pro-inflammatory cytokines. Macrophages play a role in the inflammatory process by secreting many cytokines such as tumour necrosis factor-alpha, interleukin-6, resistin and retinol binding protein-4. These cytokines and chemokines participate in low grade pro-inflammatory processes leading to insulin resistance, metabolic impairment and cardiovascular diseases. More metabolic regulators, such as fibroblast growth factor (FGF21, FGF19, FGF1, vaspin and visfatin have now been discovered but their exact roles in human diseases are still unclear. This review focuses on recent research regarding the role of adipokines and new metabolic factors in metabolic derangement or cardiovascular disease.

    Spaceflight causes adaptive changes in cardiovascular function that may deleteriously affect crew health and safety. Over the last three decades, symptoms of cardiovascular changes have ranged from postflight orthostatic tachycardia and decreased exercise capacity to serious cardiac rhythm disturbances during extravehicular activities (EVA). The most documented symptom of cardiovascular dysfunction, postflight orthostatic intolerance, has affected a significant percentage of U.S. Space Shuttle astronauts. Problems of cardiovascular dysfunction associated with spaceflight are a concern to NASA. This has been particularly true during Shuttle flights where the primary concern is the crew's physical health, including the pilot's ability to land the Orbiter, and the crew's ability to quickly egress and move to safety should a dangerous condition arise. The study of astronauts during Shuttle activities is inherently more difficult than most human research. Consequently, sample sizes have been small and results have lacked consistency. Before the Extended Duration Orbiter Medical Project (EDOMP), there was a lack of normative data on changes in cardiovascular parameters during and after spaceflight. The EDOMP for the first time allowed studies on a large enough number of subjects to overcome some of these problems. There were three primary goals of the Cardiovascular EDOMP studies. The first was to establish, through descriptive studies, a normative data base of cardiovascular changes attributable to spaceflight. The second goal was to determine mechanisms of cardiovascular changes resulting from spaceflight (particularly orthostatic hypotension and cardiac rhythm disturbances). The third was to evaluate possible countermeasures. The Cardiovascular EDOMP studies involved parallel descriptive, mechanistic, and countermeasure evaluations.

    Full Text Available OBJETIVO: Descrever marcadores antropométricos, clínicos e dietéticos associados ao risco cardiovascular em indivíduos infectados pelo vírus HIV. MÉTODOS: Realizou-se um estudo transversal com 100 indivíduos, adultos, com HIV/Aids, da cidade do Rio de Janeiro. O risco cardiovascular foi estimado pelo escore de risco de Framingham. O consumo alimentar foi avaliado por meio de um recordatório de 24 horas e de uma lista de frequência de consumo de alimentos. Para comparar variáveis, foram utilizados o teste t de Student e o teste Qui-quadrado. RESULTADOS: Dentre os indivíduos avaliados, 63% eram homens, com idade média de 41,8, DP=9,6 anos, 77% faziam uso de antirretrovirais. Escore de risco de Framingham >10% foi identificado em 53% dos indivíduos. Os principais fatores de risco cardiovascular potencialmente modificáveis identificados foram: lipoproteína de alta densidade baixo (70%, hipercolesterolemia (35%, hipertensão arterial (35%, seguidos de tabagismo (23% e glicose alta (21%.

    Full Text Available Abstract Background We have studied the possible effects of an intensive lifestyle change program on plasma fibrinogen levels, in patients with no cardiovascular disease, with elevated levels of fibrinogen, normal cholesterol levels, and a moderate estimated risk of coronary heart disease (CHD and we have also analysed whether the effect on fibrinogen is independent of the effect on lipids. Results This clinical trial was controlled, unblinded and randomized, with parallel groups, done in 13 Basic Health Areas (BHA in l'Hospitalet de Llobregat (Barcelona and Barcelona city. The study included 436 patients, aged between 35 and 75 years, with no cardiovascular disease, elevated levels of fibrinogen (> 300 mg/dl, cholesterol The evaluation of the baseline characteristics of the patients showed that both groups were homogenous. Obesity and hypertension were the most prevalent risk factors. After 24 months of the study, statistically significant changes were seen between the adjusted means of the two groups, for the following parameters: fibrinogen, plasma cholesterol, systolic and diastolic blood pressure and body mass index. Conclusion Intensive intervention to achieve lifestyle changes has shown to be effective in reducing some of the estimated CHD factors. However, the effect of intensive intervention on plasma fibrinogen levels did not correlate with the variations in cholesterol. Trial Registration ClinicalTrials.gov: NCT01089530

    We evaluated the prevalence, image appearance, associated cardiovascular anomalies, and surgical outcomes of left pulmonary artery sling (LPAS) using cardiovascular computed tomography angiography (CCTA). A retrospective search of patients from our database between October 2007 and December 2014 identified 52,200 patients with congenital heart diseases (CHD) referred for CCTA, echocardiography, or magnetic resonance imaging. Clinical information, CCTA findings, associated cardiovascular anomalies, and surgical outcomes were analyzed. We showed a hospital-based prevalence of 71 patients with LPAS (0.14%, 71/52,200) among CHD patients. Of these, 47 patients with CCTA examinations were assessed further. Most patients (40/47, 85%) had associated cardiovascular anomalies, of which ventricular septal defects (22/47, 47%), atrial septal defects (20/47, 43%), patent ductus arteriosus (16/47, 34%), persistent left superior vena cava (14/47, 30%), and abnormal branching of the right pulmonary artery (ABRPA) (14/47, 30%) were most commonly identified. In total, 28 patients underwent LPA reanastomosis and/or tracheoplasty in our center, and 5 died. LPAS had a hospital-based prevalence of 0.14% among CHD patients. ABRPA is not uncommon and must be recognized. CCTA is a feasible method for demonstrating LPAS and its associated cardiovascular anomalies for an optimal pre-operative assessment of LPAS.

    Visual interpretation of iodine-123-beta-15-(p-iodophenyl)-3(R,S)-methyl-pentadecanoic acid ({sup 123}I-BMIPP) myocardial images cannot easily detect mild reduction in tracer uptake. Objective assessment of myocardial {sup 123}I-BMIPP maldistributions at rest was attempted using a bull`s-eye map and its normal data file for detecting myocardial damage in patients with mitochondrial encephalomyopathy. Six patients, two with Kearns-Sayre syndrome and four with mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS), and 10 normal subjects were studied. Fractional myocardial uptake of 1{sup 23}I-BMIPP was also measured by dynamic static imaging to assess the global myocardial free fatty acid. These data were compared with the cardiothoracic ratio measured by chest radiography and left ventricular ejection fraction assessed by echocardiography. Abnormal cardiothoracic ratio and lower ejection fraction were detected in only one patient with Kearns-Sayre syndrome. Abnormal fractional myocardial uptake was detected in two patients (1.61%, 1.91%), whereas abnormal regional {sup 123}I-BMIPP uptake assessed by the bull`s-eye map was detected in five patients (83%). All patients showed abnormal uptake in the anterior portion, and one showed progressive atrioventricular conduction abnormality and systolic dysfunction with extended {sup 123}I-BMIPP abnormal uptake. The results suggest that assessment based on the normal data file in a bull`s-eye polar map is clinically useful for detection of myocardial damage in patients with mitochondrial encephalomyopathy.

Pharmaceutical claims show a strong tendency for patients to remain on their initially assigned treatment. With computer simulations, the impact of initial statin treatment decisions on medium- and long-term cardiovascular outcomes were examined.Patients and methods: Using the Archimedes Model, three treatment scenarios were simulated. Patients initiated treatment with simvastatin (20, 40, or 80 mg, atorvastatin (10, 20, 40, or 80 mg, or rosuvastatin (10, 20, or 40 mg, and periodically intensified treatment. The simulated population consisted of 50,025 patients, aged 45–70 years, with low-density lipoprotein cholesterol exceeding goal. The proportion of patients initiating each dose was calibrated to United States pharmacy claims. Patients not reaching goal intensified the dose of their current statin or switched to an appropriate dose of rosuvastatin at rates matching pharmacy claims. Biomarkers and major adverse cardiovascular events (MACE were tracked for 10 years and several high-risk subpopulations were analyzed. Statin models used biomarker effects from the STELLAR (Statin Therapies for Elevated Lipid Levels Compared Across Doses to Rosuvastatin trial and outcomes data from various trials.Results: Initiating therapy with rosuvastatin reduced MACE more than simvastatin or atorvastatin. The 5- year relative risk of MACE was 0.906 (95% confidence interval: 0.888–0.923; P < 0.001 for initial treatment with atorvastatin rather than simvastatin, 0.831 (0.812–0.850; P < 0.001 for rosuvastatin rather than simvastatin, and 0.918 (0.898–0.938; P < 0.001 for rosuvastatin rather than atorvastatin

    We evaluated the effectiveness of pharmacist-managed pharmacotherapy clinics in implementing and maximizing therapy with agents known to reduce the morbidity and mortality associated with cardiovascular disease. This was a retrospective chart review of 150 patients who were treated for coronary artery disease in primary care clinics. Appropriate treatment of hypercholesterolemia occurred in 96% of patients referred to a clinical pharmacy specialist, compared with 68% of those followed by primary care providers alone (p<0.0001). Eighty-five percent and 50%, respectively, achieved goal low-density lipoprotein (LDL) values below 105 mg/dl (p<0.0001). Appropriate therapy with aspirin or other antiplatelet or anticoagulant drugs was prescribed in 97% and 92%, respectively (p=0.146). As appropriate therapy with these agents was high in both groups, the ability to detect a difference between groups was limited. Among patients with an ejection fraction below 40%, appropriate therapy with an angiotensin-converting enzyme inhibitor or acceptable alternative was 89% and 69%, respectively (p<0.05). Twenty-seven cardiac events were documented in the clinical pharmacy group, versus 22 in the primary care group (p=0.475). Despite the relatively high percentage of patients reaching goal LDL in the primary care group, referral to clinical pharmacy specialists resulted in statistically significant increases in the number of patients appropriately treated for hypercholesterolemia and achieving goal LDL.

    Until recently, PET was regarded as a luxurious way of performing myocardial perfusion scintigraphy, with excellent image quality and diagnostic capabilities that hardly justified the additional cost and procedural effort. Quantitative perfusion PET was considered a major improvement over standard qualitative imaging, because it allows the measurement of parameters not otherwise available, but for many years its use was confined to academic and research settings. In recent years, however, several factors have contributed to the renewal of interest in quantitative perfusion PET, which has become a much more readily accessible technique due to progress in hardware and the availability of dedicated and user-friendly platforms and programs. In spite of this evolution and of the growing evidence that quantitative perfusion PET can play a role in the clinical setting, there are not yet clear indications for its clinical use. Therefore, the Cardiovascular Committee of the European Association of Nuclear Medicine, starting from the experience of its members, decided to examine the current literature on quantitative perfusion PET to (1) evaluate the rationale for its clinical use, (2) identify the main methodological requirements, (3) identify the remaining technical difficulties, (4) define the most reliable interpretation criteria, and finally (5) tentatively delineate currently acceptable and possibly appropriate clinical indications. The present position paper must be considered as a starting point aiming to promote a wider use of quantitative perfusion PET and to encourage the conception and execution of the studies needed to definitely establish its role in clinical practice.

    Full Text Available Abstract Background Periodontal disease (PD is an infectious clinical entity characterized by the destruction of supporting tissues of the teeth as the result of a chronic inflammatory response in a susceptible host. It has been proposed that PD as subclinical infection may contribute to the etiology and to the pathogenesis of several systemic diseases including Atherosclerosis. A number of epidemiological studies link periodontal disease/edentulism as independent risk factor for acute myocardial infarction, peripheral vascular disease, and cerebrovascular disease. Moreover, new randomized controlled clinical trials have shown an improvement on cardiovascular surrogate markers (endothelial function, sICAM, hsPCR level, fibrinogen after periodontal treatment. Nonetheless, such trials are still limited in terms of external validity, periodontal treatment strategies, CONSORT-based design and results consistency/extrapolation. The current study is designed to evaluate if periodontal treatment with scaling and root planning plus local delivered chlorhexidine improves endothelial function and other biomarkers of cardiovascular disease in subjects with moderate to severe periodontitis. Methods/Design This randomized, single-blind clinical trial will be performed at two health centers and will include two periodontal treatment strategies. After medical/periodontal screening, a baseline endothelium-dependent brachial artery flow-mediated dilatation (FMD and other systemic surrogate markers will be obtained from all recruited subjects. Patients then will be randomized to receive either supragingival/subgingival plaque cleaning and calculus removal plus chlorhexidine (treatment group or supragingival plaque removal only (control group. A second and third FMD will be obtained after 24 hours and 12 weeks in both treatment arms. Each group will consist of 49 patients (n = 98 and all patients will be followed-up for secondary outcomes and will be monitored

    About half of all deaths are due to cardiovascular disease and its complications. The economic burden on society and the healthcare system from cardiovascular disability, complications, and treatments is huge and becoming larger in the rapidly aging populations of developed countries. As conventional risk factors fail to account for part of the cases, homocysteine, a "new" risk factor, is being viewed with mounting interest. Homocysteine is a sulfur-containing intermediate product in the normal metabolism of methionine, an essential amino acid. Folic acid, vitamin B(12), and vitamin B(6) deficiency and reduced enzyme activities inhibit the breakdown of homocysteine, thus increasing the intracellular homocysteine concentration. Numerous retrospective and prospective studies have consistently found an independent relationship between mild hyperhomocysteinemia and cardiovascular disease or all-cause mortality. Starting at a plasma homocysteine concentration of approximately 10 micromol/l, the risk increase follows a linear dose-response relationship with no specific threshold level. Hyperhomocysteinemia as an independent risk factor for cardiovascular disease is thought to be responsible for about 10 percent of total risk. Elevated plasma homocysteine levels (> 12 micromol/l; moderate hyperhomocysteinemia) are considered cytotoxic and are found in 5 to 10 percent of the general population and in up to 40 percent of patients with vascular disease. Additional risk factors (smoking, arterial hypertension, diabetes, and hyperlipidemia) may additively or, by interacting with homocysteine, synergistically (and hence overproportionally) increase overall risk. Hyperhomocysteinemia is associated with alterations in vascular morphology, loss of endothelial antithrombotic function, and induction of a procoagulant environment. Most known forms of damage or injury are due to homocysteine-mediated oxidative stresses. Especially when acting as direct or indirect antagonists of

    Introducción: La hipercolesterolemia es uno de los factores de riesgo relevantes en la enfermedad cardiovascular, siendo el uso de esteroles vegetales una de las estrategias con mayor evidencia. Objetivos: Determinar la eficacia de una leche enriquecida en fitoesteroles para la disminución de marcadores de enfermedad cardiovascular en población joven adulta. Métodos: Ensayo clínico, controlado, aletorizado, doble ciego y cruzado. Los esteroles (2,24 g diarios) fueron ingeridos a través de una leche comercial, administrada en dos fases de 3 semanas respectivamente y separadas por un periodo de lavado de 2 semanas, para aquellos sujetos durante la fase de “leche de estudio”, y la misma cantidad de leche desnatada, sin esteroles, para el placebo. Al inicio y al final de cada fase se realizaron extracciones de sangre. Se recopilaron datos antropométricos, hábitos de salud y marcadores analíticos sanguíneos: perfil lipídico, hematológico, inflamación, etc. Resultados: Diecinueve personas culminaron el estudio de con una edad media de 34,68 años (±6,91). La diferencia entre los marcadores basales y finales para el colesterol- LDL, el Colesterol total y Triglicéridos fueron de 19,47 (±29,10) mg/dl, 24,47 (±30,68) mg/dl, 14,36 (±44,16) mg/dl, respectivamente. Sin cambios considerables en las fracciones de colesterol-HDL. Existen diferencias significativas, entre el placebo y la leche con esteroles para colesterol-LDL (p=0,009) y Colesterol total (p=0,003). Conclusiones: Los esteroles vegetales suministrados en un alimento de consumo habitual, como la leche, pueden ser una estrategia terapéutica no farmacológica de la hipoercolesterolemia y, por ello, una herramienta en la prevención del riesgo cardiovascular a nivel global.

    Full Text Available We assessed cardiovascular disease (CVD risk factor prevalence and risk stratification amongst adults on antiretroviral therapy in South Africa. Of the 175 patients screened, 37.8% had high blood pressure (HBP, 15.4% were current smokers, 10.4% had elevated cholesterol, and 4.1% had diabetes, but very few (3.6% had a 10-year CVD risk >10%. One-third of those with HBP, 40% of those with diabetes, and two-thirds of those with high cholesterol had not previously been diagnosed. Although participants were adherent with chronic HIV care, screening for and management of CVDRF were suboptimal, representing a missed opportunity to reduce non-AIDS morbidity and mortality.

    Background Type 2 diabetes and cardiovascular disease impose substantial clinical and economic burdens for seniors (age 65 and above) and the Medicare program. Intensive Behavioral Counseling (IBC) interventions like the National Diabetes Prevention Program (NDPP), have demonstrated effectiveness in reducing excess body weight and lowering or delaying morbidity onset. This paper estimated the potential health implications and medical savings of a digital version of IBC modeled after the NDPP. Methods and Findings Participants in this digital IBC intervention, the Omada program, include 1,121 overweight or obese seniors with additional risk factors for diabetes or heart disease. Weight changes were objectively measured via participant use of a networked weight scale. Participants averaged 6.8% reduction in body weight within 26 weeks, and 89% of participants completed 9 or more of the 16 core phase lessons. We used a Markov-based microsimulation model to simulate the impact of weight loss on future health states and medical expenditures over 10 years. Cumulative per capita medical expenditure savings over 3, 5 and 10 years ranged from $1,720 to 1,770 (3 years), $3,840 to $4,240 (5 years) and $11,550 to $14,200 (10 years). The range reflects assumptions of weight re-gain similar to that seen in the DPP clinical trial (lower bound) or minimal weight re-gain aligned with age-adjusted national averages (upper bound). The estimated net economic benefit after IBC costs is $10,250 to $12,840 cumulative over 10 years. Simulation outcomes suggest reduced incidence of diabetes by 27–41% for participants with prediabetes, and stroke by approximately 15% over 5 years. Conclusions A digital, remotely-delivered IBC program can help seniors at risk for diabetes and cardiovascular disease achieve significant weight loss, reduces risk for diabetes and cardiovascular disease, and achieve meaningful medical cost savings. These findings affirm recommendations for IBC coverage by the

    2002-02-01

    Pharmacogenetics is a field aimed at understanding the genetic contribution to inter-patient variability in drug efficacy and toxicity. Treatment of cardiovascular disease is, in most cases, guided by evidence from well-controlled clinical trials. Given the solid scientific basis for the treatment of most cardiovascular diseases, it is common for patients with a given disease to be treated in essentially the same manner. Thus, the clinical trials have been very informative about treating large groups of patients with a given disease, but are slightly less informative about the treatment of individual patients. Pharmacogenetics and pharmacogenomics have the potential of taking the information derived from large clinical trials and further refining it to select the drugs with the greatest likelihood for benefit, and least likelihood for harm, in individual patients, based on their genetic make-up. In this paper, the current literature on cardiovascular pharmacogenetics is emphasised, and how the use of pharmacogenetic/pharmacogenomic information may be particularly useful in the future in the treatment of cardiovascular diseases is also highlighted.

  4. Cardiovascular effects of gliptins.

    Scheen, André J

    2013-02-01

    Dipeptidyl peptidase 4 (DPP-4) inhibitors (commonly referred to as gliptins) are a novel class of oral antihyperglycaemic agents with demonstrated efficacy in the treatment of type 2 diabetes mellitus (T2DM). Preclinical data and mechanistic studies have indicated a possible beneficial action on blood vessels and the heart, via both glucagon-like peptide 1 (GLP-1)-dependent and GLP-1-independent effects. DPP-4 inhibition increases the concentration of many peptides with potential vasoactive and cardioprotective effects. Clinically, DPP-4 inhibitors improve several risk factors in patients with T2DM. They improve blood glucose control (mainly by reducing postprandial glycaemia), are weight neutral (or even induce modest weight loss), lower blood pressure, improve postprandial lipaemia, reduce inflammatory markers, diminish oxidative stress, and improve endothelial function. Some positive effects on the heart have also been described in patients with ischaemic heart disease or congestive heart failure, although their clinical relevance requires further investigation. Post-hoc analyses of phase II-III, controlled trials suggest a possible cardioprotective effect with a trend for a lower incidence of major cardiovascular events with gliptins than with placebo or active agents. However, the actual relationship between DPP-4 inhibition and cardiovascular outcomes remains to be proven. Major prospective clinical trials with predefined cardiovascular outcomes and involving various DPP-4 inhibitors are now underway in patients with T2DM and a high-risk cardiovascular profile.

    Fish patients with cardiovascular disorders present a challenge in terms of diagnostic evaluation and therapeutic options. Veterinarians can approach these cases in fish using methods similar to those employed for other companion animals. Clinicians who evaluate and treat fish in private, aquarium, zoologic, or aquaculture settings need to rely on sound clinical judgment after thorough historical and physical evaluation. Pharmacokinetic data and treatments specific to cardiovascular disease in fish are limited; thus, drug types and dosages used in fish are largely empiric. Fish cardiovascular anatomy, physiology, diagnostic evaluation, monitoring, common diseases, cardiac pathologic conditions, formulary options, and comprehensive references are presented with the goal of providing fish veterinarians with clinically relevant tools.

    Full Text Available Abstract Background This paper describes a methodology for comparing the effects of an eduentertainment strategy involving a music concert, and a participatory class experience involving the description and making of a healthy breakfast, as educational vehicles for delivering obesity-preventing/cardiovascular health messages to children aged 7–8 years. Methods/design This study will involve a cluster-randomised trial with blinded assessment. The study subjects will be children aged 7–8 years of both sexes attending public primary schools in the Madrid Region. The participating schools (n=30 will be randomly assigned to one of two groups: 1 Group MC, in which the children will attend a music concert that delivers obesity-preventing/cardiovascular health messages, or 2 Group HB, in which the children will attend a participatory class providing the same information but involving the description and making of a healthy breakfast. The main outcome measured will be the increase in the number of correct answers scored on a knowledge questionnaire and in an attitudes test administered before and after the above interventions. The secondary outcome recorded will be the reduction in BMI percentile among children deemed overweight/obese prior to the interventions. The required sample size (number of children was calculated for a comparison of proportions with an α of 0.05 and a β of 0.20, assuming that the Group MC subjects would show values for the measured variables at least 10% higher than those recorded for the subjects of Group HB. Corrections were made for the design effect and assuming a loss to follow-up of 10%. The maximum sample size required will be 2107 children. Data will be analysed using summary measurements for each cluster, both for making estimates and for hypothesis testing. All analyses will be made on an intention-to-treat basis. Discussion The intervention providing the best results could be recommended as part of health

    To compare the predicative ability of SYNTAX (Synergy between PCI with Taxus and Cardiac Surgery) and clinical SYNTAX scores for major adverse cardiac events (MACEs) after stent implantation in patients with coronary artery disease (CAD). Studies were identified by electronic and manual searches. Twenty-six studies were included in the meta-analysis. The pooled C-statistics of SYNTAX score for 1- and 5-year all-cause mortality (ACM) were 0.65 (95% confidence interval [CI]: 0.61-0.68) and 0.62 (95% CI: 0.59-0.65), respectively, with weak heterogeneity. The 1- and 5-year ACM pooled C-statistics for clinical SYNTAX scores were significantly higher at 0.77 and 0.71, respectively (Ps SYNTAX score for predicting 1-year ACM per unit was 1.04 (95% CI: 1.03-1.05). Calibration analysis indicated SYNTAX scores overestimated the risk of major adverse cardiac and cerebrovascular events in each risk stratum. The SYNTAX score demonstrated minimal discrimination in predicting 1- or 5-year adverse cardiovascular events after percutaneous coronary intervention in patients with CAD. The clinical SYNTAX score could further improve the predictive capability for ACM but not MACE.

    Full Text Available Global risk scores use individual level information on non-modifiable risk factors (such as age, sex, ethnicity and family history and modifiable risk factors (such as smoking status and blood pressure to predict an individual’s absolute risk of an adverse event over a specified period of time in the future. Cardiovascular risk scores have two major uses in practice. First, they can be used to dichotomise people into a group whose baseline risk, and therefore potential absolute benefit, is sufficiently high to justify the costs and risks associated with an intervention (whether treatment or prevention and a group with a lower absolute risk to whom the intervention is usually denied. Second, they can be used to assess the effectiveness of an intervention (such as smoking cessation or antihypertensive treatment at reducing an individual’s risk of future adverse events. In this context, they can be helpful in informing patients, motivating them to change their lifestyle, and reinforcing the importance of continued compliance.

    Full Text Available The constellation of dyslipidemia (hypertriglyceridemia and low levels of high-density lipoprotein cholesterol, elevated blood pressure, impaired glucose tolerance, and central obesity is now classified as metabolic syndrome, also called syndrome X. In the past few years, several expert groups have attempted to set forth simple diagnostic criteria for use in clinical practice to identify patients who manifest the multiple components of the metabolic syndrome. These criteria have varied somewhat in specific elements, but in general, they include a combination of multiple and metabolic risk factors. The most widely recognized of the metabolic risk factors are atherogenic dyslipidemia, elevated blood pressure, and elevated plasma glucose. Individuals with these characteristics, commonly manifest a prothrombotic state as well as and a proinflammatory state. Atherogenic dyslipidemia consists of an aggregation of lipoprotein abnormalities including elevated serum triglyceride and apolipoprotein B (apoB, increased small LDL particles, and a reduced level of HDL cholesterol (HDL-C. The metabolic syndrome is often referred to as if it were a discrete entity with a single cause. Available data suggest that it truly is a syndrome, ie, a grouping of atherosclerotic cardiovascular disease (ASCVD risk factors, that probably has more than one cause. Regardless of cause, the syndrome identifies individuals at an elevated risk for ASCVD. The magnitude of the increased risk can vary according to the components of the syndrome present as well as the other, non-metabolic syndrome risk factors in a particular person.

    . Gene profiling analysis shows that the expression of several genes is deregulated including PDGFRA (platelet-derived growth factor receptor) gene, encoding a receptor with tyrosine kinase activity. In angio-immunoblastic T-cell lymphomas molecular abnormalities are found in follicular helper T-cell (TFH) that express some distinctive markers such as CD10, PD-1, CXCR5 and the CXCL13 chemokine. ALK-positive anaplastic large cell lymphoma is a paradigme of T-cell lymphoma since it is associated with an X-ALK oncogenic fusion protein due to a translocation involving ALK gene at 2p23. ALK tyrosine kinase activates downstream pathways (Stat3/5b, Src kinases, PLCγ, PI3 kinase) implicated in lymphomagenesis, proliferation and protection against apoptosis. Specific ALK inhibitors are currently in clinical evaluation. Lastly several lymphomas are associated with infectious agents that play a direct (EB virus, HTLV1) or indirect role (e.g. Helicobacter pylori in MALT lymphoma) in lymphomagenesis.

    Full Text Available Abstract Background For the primary prevention of sudden cardiac death, guidelines provide left ventricular ejection fraction (EF criteria for implantable cardioverter defibrillator (ICD placement without specifying the technique by which it should be measured. We sought to investigate the potential impact of performing cardiovascular magnetic resonance (CMR for EF on ICD eligibility. Methods The study population consisted of patients being considered for ICD implantation who were referred for EF assessment by CMR. Patients who underwent CMR within 30 days of echocardiography were included. Echocardiographic EF was determined by Simpson’s biplane method and CMR EF was measured by Simpson’s summation of discs method. Results Fifty-two patients (age 62±15 years, 81% male had a mean EF of 38 ± 14% by echocardiography and 35 ± 14% by CMR. CMR had greater reproducibility than echocardiography for both intra-observer (ICC, 0.98 vs 0.94 and inter-observer comparisons (ICC 0.99 vs 0.93. The limits of agreement comparing CMR and echocardiographic EF were – 16 to +10 percentage points. CMR resulted in 11 of 52 (21% and 5 of 52 (10% of patients being reclassified regarding ICD eligibility at the EF thresholds of 35 and 30% respectively. Among patients with an echocardiographic EF of between 25 and 40%, 9 of 22 (41% were reclassified by CMR at either the 35 or 30% threshold. Echocardiography identified only 1 of the 6 patients with left ventricular thrombus noted incidentally on CMR. Conclusions CMR resulted in 21% of patients being reclassified regarding ICD eligibility when strict EF criteria were used. In addition, CMR detected unexpected left ventricular thrombus in almost 10% of patients. Our findings suggest that the use of CMR for EF assessment may have a substantial impact on management in patients being considered for ICD implantation.

    Living organisms on the earth live dependent on the sun. Human beings are unexceptional. Plants with chlorophyll on the earth capture energy radiated from the sun and produce carbohydrate and oxygen from carbon dioxide and water using the energy from the sun. Herbivorous animals eat plants, carnivorous ones eat herbivorous ones and human beings eat both with a small amount of vitamins and minerals. Food including carbohydrate, protein and lipid which is digested by the gastroenteric system and mainly absorbed through the small intestine. Finally, nutrients from the digestive system and oxygen from the lungs are brought to the cells or the tissue through the cardiovascular system. Acetyl-CoA from food and oxygen from the lungs are chemically burned in the mitochondria to produce a lot of ATP. On the way of ATP production, unfavorable free radicals are inevitably produced to result in cancer and/or atherosclerosis. Cardiovascular system delivers oxygen and nutrients to the tissue or the cells. Literally, it is a pipe line for life support and then we must maintain cardiovascular system well to live long in good health. And therefore, it is essential to find cardiovascular abnormality as early as possible. Cardiovascular biomarkers such as BNP and NT-proBNP for screening for heart failure, RemL-C for screening for metabolic syndrome, cystatin C for screening for renal impairment and high sensitive troponin I, T for screening for ischemic myocardial damage have been greatly expected as tools to find early cardiovascular disorders for long survival in health examination and clinical practice.

    Full Text Available Background: Quercetin has been distributed in a wide range of foods, but some of its known effects in vitro, are not proven in human studies. Therefore, the aim of this study was evaluation of the effects of quercetin intake on cardiovascular risk factors and inflammatory biomarkers in women with type 2 diabetes. Methods: This double-blind randomized clinical trial was carried out on 72 women for 10 weeks. Subjects were assigned to quercetin and placebo groups using a permutated block randomization of size two. Quercetin was given to participants as a 500 mg capsule daily. Biochemical variables were measured at baseline and at the end of the study, and changes were compared using appropriate statistical methods. Results: Compared with placebo, quercetin intake decreased systolic blood pressure significantly (−8.8 ± 9.3 vs. −3.5 ± 11.7, P = 0.04. Although changes in diastolic blood pressure between the groups was not significant ( P = 0.19, high-density lipoprotein cholesterol (HDL-C was significantly decreased in both groups while changes in total cholesterol, low-density lipoprotein cholesterol (LDL-C, triglycerides (TG and ratio of TG/HDL-C and LDL-C/HDL-C were not significant between and within groups. Quercetin supplementation significantly reduced the serum concentration of tumor necrosis factor-α (TNF-α and interleukin-6 (IL-6 ( P = 0.01 and P < 0.0001, respectively; however, the mean changes in serum levels of IL-6, TNF-α, and high-sensitivity C-reactive protein were not significant between the groups. Conclusions: Quercetin supplementation reduced systolic blood pressure significantly but had no effect on other cardiovascular risk factors and inflammatory biomarkers. Considering the biological effects of quercetin in vitro, we need more studies with a stronger design and sample size with different doses of quercetin.

    2014-01-01

    Optogenetics is an exciting new technology in which viral gene or cell delivery is used to inscribe light sensitivity in excitable tissue to enable optical control of bioelectric behavior. Initial progress in the fledgling domain of cardiac optogenetics has included in vitro expression of various light-sensitive proteins in cell monolayers and transgenic animals to demonstrate an array of potentially useful applications, including light-based pacing, silencing of spontaneous activity, and spiral wave termination. In parallel to these developments, the cardiac modeling community has developed a versatile computational framework capable of realistically simulating optogenetics in biophysically detailed, patient-specific representations of the human heart, enabling the exploration of potential clinical applications in a predictive virtual platform. Towards the ultimate goal of assessing the feasibility and potential impact of optogenetics-based therapies in cardiovascular medicine, this review provides (1) a detailed synopsis of in vivo, in vitro, and in silico developments in the field and (2) a critical assessment of how existing clinical technology for gene/cell delivery and intra-cardiac illumination could be harnessed to achieve such lofty goals as light-based arrhythmia termination.

    Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive aged women. PCOS incorporates not only symptoms related to the reproductive system but also a clustering of systemic metabolic abnormalities that are linked with increased risk for cardiovascular disease (CVD). More specifically, metabolic aberrations such as impaired glucose and lipid metabolism, accompanied by increased low-grade inflammation as well as elevated coagulation factors appear to contribute to the increased cardiovascular risk. Even though many studies have indicated a rise in surrogate biomarkers of CVD in women with PCOS, it is still doubtful to what extent and magnitude this elevation can be translated to real cardiovascular events. Furthermore, the cardiovascular risk factors appear to vary significantly in the different phenotypes of the syndrome. Women with PCOS have the potential for early atherosclerosis, myocardial and endothelial dysfunction. Whether or not PCOS women are at real cardiovascular risk compared to controls remains between the verge of theoretical and real threat for the PCOS women at any age but particularly in the post menopausal state. Interestingly, although the presence of the CVD risk factors is well documented in PCOS women, their combination on different phenotypes may play a role, which eventually results in a spectrum of clinical manifestations of CVD with variable degree of severity. The present manuscript aims to review the interaction between PCOS and the combination of several cardiovascular risk factors.

    Epigenetic modifications include DNA methylation, his-tone modifications, and micro RNA. Gene alterations have been found to be associated with cardiovascular diseases, and epigenetic mechanisms are continuously being studied to find new useful strategies for the clinical management of afflicted patients. Numerous cardiovascular disorders are characterized by the abnormal methylation of Cp G islands and so specific drugs that could inhibit DNA methyltransferase directly or by reducing its gene expression(e.g., hydralazine and procainamide) are currently under investigation. The anti-proliferative and anti-inflammatory properties of histone deacetylase inhibitors and their cardio-protective effects have been confirmed in preclinical studies. Furthermore, the regulation of the expression of micro RNA targets through pharmacological tools is still under development. Indeed, large controlled trials are required to establish whether current possible candidate antisense micro RNAs could offer better therapeutic benefits in clinical practice. Here, we updated therapeutic properties, side effects, and feasibility of eme-rging epigenetic-based strategies in cardiovascular diseases by highlighting specific problematic issues that still affect the development of large scale novel therapeutic protocols.

    Neuroendocrine abnormalities are common in Parkinson's disease (PD) and include disruption of melatonin secretion, disturbances of glucose, insulin resistance and bone metabolism, and body weight changes. They have been associated with multiple non-motor symptoms in PD and have important clinical consequences, including therapeutics. Some of the underlying mechanisms have been implicated in the pathogenesis of PD and represent promising targets for the development of disease biomarkers and neuroprotective therapies. In this systems-based review, we describe clinically relevant neuroendocrine abnormalities in Parkinson's disease to highlight their role in overall phenotype. We discuss pathophysiological mechanisms, clinical implications, and pharmacological and non-pharmacological interventions based on the current evidence. We also review recent advances in the field, focusing on the potential targets for development of neuroprotective drugs in Parkinson's disease and suggest future areas for research.

    Platelet surface expression levels of stromal cell derived factor 1 (SDF-1) are elevated in acute coronary syndrome and associated with LVEF% improvement after myocardial infarction (MI). Platelet SDF-1 might facilitate thrombus formation and endomyocardial expression of SDF-1 is enhanced in inflammatory cardiomyopathy and positively correlates with myocardial fibrosis. The influence of platelet SDF-1 on outcome in the patients with symptomatic coronary artery disease (CAD) is to the best of our knowledge unknown. Blood samples of 608 consecutive CAD patients were collected during the percutaneous coronary intervention and analyzed for surface expression of SDF-1 by flow cytometry. The primary combined endpoint was defined as the composite of either MI, or ischemic stroke, or all-cause death. Secondary endpoints were defined as the aforementioned single events. The patients with baseline platelet SDF-1 levels above the third quartile showed a significantly worse cumulative event-free survival when compared to the patients with lower baseline SDF-1 levels (first to third quartile) (log rank 0.009 for primary combined endpoint and log rank 0.016 for secondary endpoint all-cause death). Multivariate Cox regression analysis showed that SDF-1 levels above the third quartile were independently associated with the primary combined endpoint and the secondary endpoint all-cause death. We provide first clinical evidence that high platelet expression levels of SDF-1 influence clinical outcomes in CAD patients in a negative way.

    The purpose of this study was to evaluate the prevalence of an abnormal stress myocardial perfusion study in a cohort of truly asymptomatic patients with type 2 diabetes mellitus using myocardial perfusion imaging by means of single photon emission computed tomography (SPECT). Secondly, we determined which clinical characteristics may predict an abnormal stress myocardial perfusion study in this population. A total of 120 asymptomatic patients (mean age 53{+-}10 years) with type 2 diabetes mellitus and one or more risk factors for coronary artery disease were prospectively recruited from an outpatient diabetes clinic. All patients underwent myocardial perfusion imaging by means of adenosine {sup 99m}Tc sestamibi SPECT. Images were evaluated for the presence of perfusion abnormalities as well as other nonperfusion abnormalities that may indicate extensive ischaemia, including left ventricular dysfunction (defined as a left ventricular ejection fraction <45%), transient ischaemic dilatation and adenosine-induced ST segment depression. Multivariable analysis was performed using a backward selection strategy to identify potential predictors for an abnormal stress myocardial perfusion study. Finally, all patients were followed up for 12 months to determine the occurrence of cardiovascular events: (1) cardiac death, (2) nonfatal myocardial infarction, (3) unstable angina requiring hospitalization, (4) revascularization, or (5) stroke. Of the 120 patients, 40 (33%) had an abnormal stress study, including myocardial perfusion abnormalities in 30 patients (25%). In 10 patients (8%), indicators of extensive (possibly balanced ischaemia) were observed in the absence of abnormal perfusion. The multivariable analysis identified current smoking, duration of diabetes and the cholesterol/high-density lipoprotein (HDL) ratio as independent predictors of an abnormal stress study. During a follow-up period of 12 months six patients (5%) had a cardiovascular event. The current study

  11. The Effect of Antihypertensive Treatment on Cardiovascular Events——A Meta-Analysis of Four Clinical Trials in China

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Objective The pooled results of four large-scale clinical trials of antihypertensive treatments carried out in China were assessed, with an overall study population of 10,457 patients. Methods The fixed effect model was used for data analysis. Results A pooled analysis at the individual level showed that the average time of treatment was 3.4 years, after which an average reduction in blood pressure of 9/4 mmHg was found. The meta-analysis showed that stroke was reduced by 36% (95% CI 25%-46%, P0.05), whereas the significant reduction in stroke was epidemiologically expected. Conclusion The benefit of antihypertensive treatment obtained was mostly due to a reduction in the incidence of stroke.

    This paper discusses the possibility of using observer-based approaches for cardiovascular anomalies detection and isolation. We consider a lumped parameter model of the cardiovascular system that can be written in a form of nonlinear state-space representation. We show that residuals that are sensitive to variations in some cardiovascular parameters and to abnormal opening and closure of the valves, can be generated. Since the whole state is not easily available for measurement, we propose to associate the residual generator to a robust extended kalman filter. Numerical results performed on synthetic data are provided.

  14. Localization of microfibrillar-associated protein 4 (MFAP4 in human tissues: clinical evaluation of serum MFAP4 and its association with various cardiovascular conditions.

    Helle Wulf-Johansson

    Full Text Available Microfibrillar-associated protein 4 (MFAP4 is located in the extracellular matrix (ECM. We sought to identify tissues with high levels of MFAP4 mRNA and MFAP4 protein expression. Moreover, we aimed to evaluate the significance of MFAP4 as a marker of cardiovascular disease (CVD and to correlate MFAP4 with other known ECM markers, such as fibulin-1, osteoprotegerin (OPG, and osteopontin (OPN. Quantitative real-time PCR demonstrated that MFAP4 mRNA was more highly expressed in the heart, lung, and intestine than in other elastic tissues. Immunohistochemical studies demonstrated high levels of MFAP4 protein mainly at sites rich in elastic fibers and within blood vessels in all tissues investigated. The AlphaLISA technique was used to determine serum MFAP4 levels in a clinical cohort of 172 patients consisting of 5 matched groups with varying degrees of CVD: 1: patients with ST elevation myocardial infarction (STEMI, 2: patients with non-STEMI, 3: patients destined for vascular surgery because of various atherosclerotic diseases (stable atherosclerotic disease, 4: apparently healthy individuals with documented coronary artery calcification (CAC-positive, and 5: apparently healthy individuals without signs of coronary artery calcification (CAC-negative. Serum MFAP4 levels were significantly lower in patients with stable atherosclerotic disease than CAC-negative individuals (p<0.05. Furthermore, lower serum MFAP4 levels were present in patients with stable atherosclerotic disease compared with STEMI and non-STEMI patients (p<0.05. In patients with stable atherosclerotic disease, positive correlations between MFAP4 and both fibulin-1 (ρ = 0.50; p = 0.0244 and OPG (ρ = 0.62; p = 0.0014 were found. Together, these results indicate that MFAP4 is mainly located in elastic fibers and is highly expressed in blood vessels. The present study suggests that serum MFAP4 varies in groups of patients with different cardiovascular conditions

    Cardiovascular morbidity and mortality are increased in acromegaly. In fact, GH and IGF-I excess induces a specific cardiomyopathy. The early stage of acromegaly is characterized by the hyperkinetic syndrome (high heart rate and increased systolic output). Frequently, concentric biventricular hypertrophy and diastolic dysfunction occur in acromegaly, leading to an impaired systolic function ending in heart failure if the disease is untreated or unsuccessfully untreated. Besides, abnormalities of cardiac rhythm and of valves have been also described in acromegaly. The coexistence of other complications, such as arterial hypertension and diabetes, aggravates the acromegalic cardiomyopathy. The suppression of GH/IGF-I following an efficacious therapy could decrease left ventricular mass and improve cardiac function. In conclusion, a careful evaluation of cardiac function, morphology and activity seems to be mandatory in acromegaly.

    Background Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. Objective We sought to document the frequency and clinical presentation of nail abnormalities in vitiligo patients compared to healthy volunteers. We also examined the correlations between nail abnormalities and various clinical parameters. Methods This study included 100 vitiligo patients and 100 healthy subjects. Full medical histories were collected from the subjects, who underwent thorough general and nail examinations. All nail changes were noted. In the event of clinical suspicion of a fungal infection, additional mycological investigations were performed. Results Nail abnormalities were more prevalent in the patients (78%) than in the controls (55%) (p=0.001). Longitudinal ridging was the most common finding (42%), followed by (in descending order): leukonychia, an absent lunula, onycholysis, nail bed pallor, onychomycosis, splinter hemorrhage and nail plate thinning. The frequency of longitudinal ridging was significantly higher in patients than in controls (p<0.001). Conclusions Nail abnormalities were more prevalent in vitiligo patients than in controls. Systematic examination of the nails in such patients is useful because nail abnormalities are frequent. However, the causes of such abnormalities require further study. Longitudinal ridging and leukonychia were the most common abnormalities observed in this study. PMID:27579738

    Full Text Available Background: AUB is a common but complicated clinical presentation and occurs in 15-20% of women between menarche to menopause and significantly affects the women's health. Women with thyroid dysfunction often have menstrual irregularities, infertility and increased morbidity during pregnancy. The objective of present study is to find the correlation between thyroid disorders and AUB in perimenopausal women attending gynecology OPD. Methods: In the present study, fifty five patients with AUB were included and were evaluated for the cause including thyroid abnormality. Thyroid function tests were done in all patients. Results: Among 55 patients, 12 patients were diagnosed as hypothyroidism and 7 as hyperthyroidism, women with AUB 36 (65.4% were euthyroid. Among 19 women with thyroid abnormality, heavy menstrual bleeding was seen in 8 (42% women, 6 (31.57% had polymenorrhagia, 5 (26.31% had oligomenorrhoea. The frequent menstrual abnormality in women with hypothyroidism (12 women was heavy menstrual bleeding in 5 (41.6% women, 3 (25% had oligomennorhoea, 4 (33.3% had polymenorrhagia. Out of 7 women with hyperthyroidism, 2 (28.57% had oligomenorrhoea, 3 (42.8% had heavy menstrual bleeding, 2 (28.57% had polymenorrhagia. In a total of 55 patients with AUB, 11 (20% had structural abnormalities in uterus and ovaries. 5 (9% had adenomyosis, 3 (5.4% had ovarian cysts, 3 (5.4% had fibroids. Conclusions: It is important to screen all women for thyroid abnormality who are presenting with AUB especially with non-structural causes of AUB. Correction of thyroid abnormalities also relieves AUB. This will avoid unnecessary hormonal treatment and surgery. [Int J Res Med Sci 2015; 3(11.000: 3250-3253

    Toxocariasis is a parasitic infection produced by helminths that cannot reach their adult stage in humans. For their etiological species (Toxocara canis and Toxocara cati), man is a paratenic host. Infection by such helminths can produce a variety of clinical manifestations, such as: visceral larvae migrans syndrome, ocular larvae migrans syndrome and covert toxocariasis. In the visceral larvae migrans syndrome, the organs that are mainly involved include liver, lungs, skin, nervous system, muscles, kidneys and the heart. Regarding the latter, the importance of cardiovascular manifestations in toxocariasis, as well as its clinical relevance, has increasingly begun to be recognized. The current article is based on a systematic information search, focused mainly on the clinical and pathological aspects of cardiovascular manifestations in toxocariasis, including its pathophysiology, laboratory findings, diagnosis and therapeutical options, with the objective of highlighting its importance as a zoonosis and its relevance to the fields of cardiovascular medicine in adults and children.

    Full Text Available Fraser D RussellSchool of Health and Sport Sciences, Faculty of Science, Health and Education, University of the Sunshine Coast, Sippy Downs, Queensland, AustraliaAbstract: Cardiovascular function is modulated by neuronal transmitters, circulating hormones, and factors that are released locally from tissues. Urotensin II (UII is an 11 amino acid peptide that stimulates its’ obligatory G protein coupled urotensin II receptors (UT to modulate cardiovascular function in humans and in other animal species, and has been implicated in both vasculoprotective and vasculopathic effects. For example, tissue and circulating concentrations of UII have been reported to increase in some studies involving patients with atherosclerosis, heart failure, hypertension, preeclampsia, diabetes, renal disease and liver disease, raising the possibility that the UT receptor system is involved in the development and/or progression of these conditions. Consistent with this hypothesis, administration of UT receptor antagonists to animal models of cardiovascular disease have revealed improvements in cardiovascular remodelling and hemodynamics. However, recent studies have questioned this contributory role of UII in disease, and have instead postulated a protective effect on the cardiovascular system. For example, high concentrations of circulating UII correlated with improved clinical outcomes in patients with renal disease or myocardial infarction. The purpose of this review is to consider the regulation of the cardiovascular system by UII, giving consideration to methodologies for measurement of plasma concentrations, sites of synthesis and triggers for release.Keywords: urotensin II, cardiovascular disease, heart failure, hypertension

    2014-01-17

    Vitamin D plays a classical hormonal role in skeletal health by regulating calcium and phosphorus metabolism. Vitamin D metabolites also have physiological functions in nonskeletal tissues, where local synthesis influences regulatory pathways via paracrine and autocrine mechanisms. The active metabolite of vitamin D, 1α,25-dihydroxyvitamin D, binds to the vitamin D receptor that regulates numerous genes involved in fundamental processes of potential relevance to cardiovascular disease, including cell proliferation and differentiation, apoptosis, oxidative stress, membrane transport, matrix homeostasis, and cell adhesion. Vitamin D receptors have been found in all the major cardiovascular cell types including cardiomyocytes, arterial wall cells, and immune cells. Experimental studies have established a role for vitamin D metabolites in pathways that are integral to cardiovascular function and disease, including inflammation, thrombosis, and the renin-angiotensin system. Clinical studies have generally demonstrated an independent association between vitamin D deficiency and various manifestations of degenerative cardiovascular disease including vascular calcification. However, the role of vitamin D supplementation in the management of cardiovascular disease remains to be established. This review summarizes the clinical studies showing associations between vitamin D status and cardiovascular disease and the experimental studies that explore the mechanistic basis for these associations.

    Full Text Available Elevated risk of fatal and non-fatal cardiovascular events is associated with high prevalence of peripheral arterial disease, with assessment through the ankle-brachial index (ABI. This study aimed to demonstrate that the ABI and the Edinburgh Claudication Questionnaire are tools to be used by nurses in prevention and/or treatment of CVD (cardiovascular disease. A cross-sectional study was carried out with patients from a cardiovascular clinic. The Edinburgh Claudication Questionnaire was applied and the ABI was measured with the formula (ABI= Blood Pressure Ankle/Blood Pressure Brachial. A total of 115 patients were included, most were females (57.4%, aged 60.6 ± 12.5 years. The most prevalent risk factors were hypertension (64.3%, physical inactivity (48.7% and family history (58.3%. The study showed that abnormal ABI was frequently found and 42.6% of the patients with abnormal ABI showed intermittent claudication. The method to evaluate the ABI associated to the Edinburg Claudication Questionnaire, can be easily used by nurses in the clinical evaluation of asymptomatic and symptomatic CVD patients.

  5. Methoxistasis: integrating the roles of homocysteine and folic acid in cardiovascular pathobiology.

    2013-08-15

    Over the last four decades, abnormalities in the methionine-homocysteine cycle and associated folate metabolism have garnered great interest due to the reported link between hyperhomocysteinemia and human pathology, especially atherothrombotic cardiovascular disease. However, clinical trials of B-vitamin supplementation including high doses of folic acid have not demonstrated any benefit in preventing or treating cardiovascular disease. In addition to the fact that these clinical trials may have been shorter in duration than appropriate for modulating chronic disease states, it is likely that reduction of the blood homocysteine level may be an oversimplified approach to a complex biologic perturbation. The methionine-homocysteine cycle and folate metabolism regulate redox and methylation reactions and are, in turn, regulated by redox and methylation status. Under normal conditions, a normal redox-methylation balance, or "methoxistasis", exists, coordinated by the methionine-homocysteine cycle. An abnormal homocysteine level seen in pathologic states may reflect a disturbance of methoxistasis. We propose that future research should be targeted at estimating the deviation from methoxistasis and how best to restore it. This approach could lead to significant advances in preventing and treating cardiovascular diseases, including heart failure.

    Arterial hypertension is an important cardiovascular risk factor. The benefit drawn from decreasing and normalizing the blood pressure level is indisputable. The ACCOMPLISH study performed in patients older than 65 with systolic hypertension and a high cardiovascular risk pointed out the interest of well choosing the antihypertensive combination to reduce this risk beyond the decrease of blood pressure. The association of benazepril (an angiotensin converting enzyme inhibitor or ACEI) and amlodipine (a calcium antagonist) has shown significant early cardiovascular protection in such patients as compared to the classic association including the same ACEI and hydrochlorothiazide, in spite of the same target blood pressure reached. This important finding does not contest the interest of a well controlled blood pressure in hypertension, but probably will modify our first antihypertensive combination choice in the future in patients with such cardiovascular profile.

    During the past 9 yr, 187,529 Sternheimer-Malbin-stained urinary sediments were examined as routine urinalysis specimens from patients attending the National Cardiovascular Center in Osaka, Japan. Abnormal cells were found in 20 patients who did not have clinical diagnoses of malignancy. Malignant cytological changes in 18 patients resulted in a rate of 1 case in 6,751 patients; the two remaining specimens with abnormal cells showed polyomavirus infection. This article describes our experience in the diagnosis of malignant cells of the urinary tract through the cooperation of the clinical and cytological laboratories. Since in Japan, the rate of death for bladder cancer is similar to 1 in 6,751, this method seems to be of great use in the diagnosis of urinary tract malignancies.

    Cardiac magnetic resonance (CMR) has increasingly proved to be a valuable diagnostic tool for evaluating patients with suspected myocarditis. The objective of this study was to evaluate the diagnostic value of functional and morphological parameters including tissue characterization in patients with ''infarct-like myocarditis''. 43 patients with clinically verified cases of ''infarct-like myocarditis'' (median time to MRI scanning after admission for acute symptoms 3 days) and 35 control patients matched by age and sex were included in this retrospective case control study. In this study we used a 1.5 T MRI scanner conducting steady-state-free-precession sequences, T2-weighted imaging, T1-weighted imaging before and after contrast administration and late gadolinium enhancement sequences. According to the recommendations for CMR diagnosis of myocarditis (Lake Louise consensus criteria), a scan was positive for acute myocarditis if 2 of 3 CMR criteria were present. 30 % of the patients with ''infarct-like myocarditis'' had a reduced left ventricular ejection fraction, 11 % had an increased LV end-diastolic volume index and 35 % had an increased LV mass index. The sensitivity of wall motion abnormalities was 63 % with a regional distribution in 49 %. In 47 % of cases regional wall motion abnormalities were present in the lateral left ventricular segments. Pericardial effusions were discovered in 65 % of cases with a circular appearance in 21 % and focal manifestation in 44 %. The diagnostic sensitivity, specificity, and accuracy of CMR in patients with ''infarct-like myocarditis'' were 67 %, 100 % and 82 %, respectively. The LGE alone was the most sensitive test parameter with 86 %, providing a specificity of 100 % and accuracy of 92 %. Our study results can be applied to the subgroup of patients with ''infarct-like myocarditis'', where we found that LGE alone was the

    More than 10 million people, many elderly and likely to harbor cardiovascular (CV) disease, embark on cruise ship travel worldwide every year. The clinical presentation and outcome of CV emergencies presenting during cruise ship travel remain largely unknown. Our department provides contracted cardiology consultations to several large cruise lines. We prospectively maintained a registry of all such consultations during a 2-year period. One hundred consecutive patients were identified (age 66 +/- 14 years, range 18 to 90, 76% men). The most common symptom was chest pain (50%). The most common diagnosis was acute coronary syndrome (58%; ST elevation in 21% and non-ST elevation in 37%). On-board mortality was 3%. Overall, 73% of patients required hospital triage. Of the 25 patients triaged to our institution, 17 underwent a revascularization procedure. One patient died. Ten percent of patients had cardiac symptoms in the days or weeks before boarding; all required hospital triage. Access to a baseline electrocardiogram would have been clinically useful in 23% of cases. In conclusion, CV emergencies, such as acute coronary syndrome and heart failure, are not uncommon on cruise ships. They are often serious, requiring hospital triage and coronary revascularization. A pretravel medical evaluation is recommended for passengers with a cardiac history or a high-risk profile. Passengers should be encouraged to bring a copy of their electrocardiogram on board if abnormal. Cruise lines should establish mechanisms for prompt consultation and triage.

    Meiotic anomalies, as reviewed here, are synaptic chromosome abnormalities, limited to germ cells that cannot be detected through the study of the karyotype. Although the importance of synaptic errors has been underestimated for many years, their presence is related to many cases of human male infertility. Synaptic anomalies can be studied by immunostaining of synaptonemal complexes (SCs), but in this case their frequency is probably underestimated due to the phenomenon of synaptic adjustment. They can also be studied in classic meiotic preparations, which, from a clinical point of view, is still the best approach, especially if multiplex fluorescence in situ hybridization is at hand to solve difficult cases. Sperm chromosome FISH studies also provide indirect evidence of their presence. Synaptic anomalies can affect the rate of recombination of all bivalents, produce achiasmate small univalents, partially achiasmate medium-sized or large bivalents, or affect all bivalents in the cell. The frequency is variable, interindividually and intraindividually. The baseline incidence of synaptic anomalies is 6-8%, which may be increased to 17.6% in males with a severe oligozoospermia, and to 27% in normozoospermic males with one or more previous IVF failures. The clinical consequences are the production of abnormal spermatozoa that will produce a higher number of chromosomally abnormal embryos. The indications for a meiotic study in testicular biopsy are provided.

    Acute inversion injuries of the ankle are the most common sports accidents, accounting for approximately 10% of emergency room admissions. In up to 85%, an injury of the lateral collateral ligaments is observed. Classically, the assessment of these injuries has relied on clinical examination and radiographs, including stress views. The aim of our study was to correlate prospectively the findings of high-field 3 T MRI in acute ankle distortion with clinical outcome. During a 6-month period, 38 patients were prospectively included. MRI was performed within 48 h of trauma and clinical examination using a protocol consisting of axial T2-weighted and coronal and sagittal T1-weighted images and a sagittal proton density (PDw) sequence. Each ligament injury was graded on a three-point scale. Functional outcome was evaluated using the AOFAS ankle-hindfoot scale. In 24/38 patients (63.12%), ligament injury was observed. In 22/24 cases, this was an injury of the lateral ligaments and in 2/24 cases of the medial ligaments. Injury of the syndesmosis occurred in three patients, a bone bruise in four, and an osteochondral lesion in three cases. Patients with an injury of two or more ligaments or a bone bruise had a lower AOFAS score and returned to sports activities and full weight-bearing later (P < 0.01). MR imaging at 3 Tesla is an independent predictor for clinical outcome. Therefore MRI may be beneficial in those cases where the findings influence further treatment. (orig.)

  8. Stress and atherosclerotic cardiovascular disease.

    Inoue, Nobutaka

    2014-01-01

    Recent major advances in medical science have introduced a wide variety of treatments against atherosclerosis-based cardiovascular diseases, which has led to a significant reduction in mortality associated with these diseases. However, atherosclerosis-based cardiovascular disease remains a leading cause of death. Furthermore, progress in medical science has demonstrated the pathogenesis of cardiovascular disease to be complicated, with a wide variety of underlying factors. Among these factors, stress is thought to be pivotal. Several types of stress are involved in the development of cardiovascular disease, including oxidative stress, mental stress, hemodynamic stress and social stress. Accumulating evidence indicates that traditional risk factors for atherosclerosis, including diabetes, hyperlipidemia, hypertension and smoking, induce oxidative stress in the vasculature. Oxidative stress is implicated in the pathogenesis of endothelial dysfunction, atherogenesis, hypertension and remodeling of blood vessels. Meanwhile, mental stress is a well-known major contributor to the development of cardiovascular disease. The cardiovascular system is constantly exposed to hemodynamic stress by the blood flow and/or pulsation, and hemodynamic stress exerts profound effects on the biology of vascular cells and cardiomyocytes. In addition, social stress, such as that due to a lack of social support, poverty or living alone, has a negative impact on the incidence of cardiovascular disease. Furthermore, there are interactions between mental, oxidative and hemodynamic stress. The production of reactive oxygen species is increased under high levels of mental stress in close association with oxidative stress. These stress responses and their interactions play central roles in the pathogenesis of atherosclerosis-based cardiovascular disease. Accordingly, the pathophysiological and clinical implications of stress are discussed in this article.

CR servicesare generally provided in an outpatient as comprehensive, long-term programs involving medicalevaluation, prescribed exercise, cardiac risk factor modification, education and counseling. This includesnutritional therapies, weight loss program management of lipid abnormalities with diet and medication,blood pressure control, diabetes management and stress management. The exercise component of a totalapproach to rehabilitation helps to overcome the fears and anxieties that so many people experience aftera heart attack. Aerobic exercise training program improves cardiovascular fitness in both healthyindividual and cardiac patients. Cardiac rehabilitation prevents and treat cardiovascular disease, reducescardiac risk factors, improving patient’s exercise capacity and enhancing quality of life. Aerobicexercise with intensity of approximately 60 to 70% of the maximal heart rate for 30 to 60 minutes, 3 to 4times a week, for 4 to 6 weeks enhances exercise capacity.

    Genomic copy number microarrays have significantly increased the diagnostic yield over a karyotype for clinically significant imbalances in individuals with developmental delay, intellectual disability, multiple congenital anomalies, and autism, and they are now accepted as a first tier diagnostic test for these indications. As it is not feasible to validate microarray technology that targets the entire genome in the same manner as an assay that targets a specific gene or syndromic region, a new paradigm of validation and regulation is needed to regulate this important diagnostic technology. We suggest that these microarray platforms be evaluated and manufacturers regulated for the ability to accurately measure copy number gains or losses in DNA (analytical validation) and that the subsequent interpretation of the findings and assignment of clinical significance be determined by medical professionals with appropriate training and certification. To this end, the American College of Medical Genetics, as the professional organization of board-certified clinical laboratory geneticists, herein outlines recommendations for the design and performance expectations for clinical genomic copy number microarrays and associated software intended for use in the postnatal setting for detection of constitutional abnormalities.

    Mentalis muscle responses to electrical stimulation of the zygomatic branch of the facial nerve are considered abnormal muscle responses (AMRs) and can be used to monitor the success of decompression in microvascular decompression (MVD) surgery. The aim of this study was to compare the long-term outcome of MVD surgery in which the AMR disappeared to the outcome of surgery in which the AMR persisted. From 2005 to 2009, 131 patients with hemifacial spasm received MVD surgery with intraoperative monitoring of AMR. At 1 week postsurgery, spasms had resolved in 82% of cases in the AMR-disappearance group and 46% of cases in the persistent-AMR group, mild spasms were present in 10% of cases in the AMR-disappearance group and 31% of cases in the persistent-AMR group, and moderate were present spasms in 8% of cases in the AMR-disappearance group and 23% of cases in the persistent-AMR group (P spasms had resolved in 92% of cases in the AMR-disappearance group and 84% of cases in the persistent-AMR group, mild spasms were present in 6% of cases in the AMR-disappearance group and 8% of cases in the persistent-AMR group, and moderate spasms were present in 3% of cases in the AMR-disappearance group and 8% of the cases in the persistent-AMR group (P = 0.56). These results indicate that the long-term outcome of MVD surgery in which the AMR persisted was no different to that of MVD surgery in which the AMR disappeared.

    Two concepts, positive health and cardiovascular health, have emerged recently from the respective fields of positive psychology and preventive cardiology. These parallel constructs are converging to foster positive cardiovascular health and a growing collaboration between psychologists and cardiovascular scientists to achieve significant improvements in both individual and population cardiovascular health. We explore these 2 concepts and note close similarities in the measures that define them, the health states that they aim to produce, and their intended long-term clinical and public health outcomes. We especially examine subjective health assets, such as optimism, that are a core focus of positive psychology, but have largely been neglected in preventive cardiology. We identify research to date on positive cardiovascular health, discuss its strengths and limitations thus far, and outline directions for further engagement of cardiovascular scientists with colleagues in positive psychology to advance this new field.

    Cardiovascular diseases are uncommon among trained athletes. Their occurrences mostly depend on the individual's age and fitness levels. Adequate understanding of the cardiovascular adaptations undergone by the competitive athletes' heart is of paramount importance in order to differentiate them from serious cardiovascular conditions. Diagnosing these abnormalities early may prevent rare but devastating potential complications associated with athletic activities and defines appropriate activity restrictions to minimize the risk of sudden cardiac death. This article will review concerns related to competitive athlete's cardiovascular adaptations and diseases, in light of specific recommendations presented in the 36th Bethesda Conference guidelines.

    Full Text Available The increased incidence of cardiovascular diseases (CVDs has stimulated research for substances that could improve cardiovascular health. Among them, resveratrol (RES, a polyphenolic compound notably present in grapes and red wine, has been involved in the “French paradox”. RES is known for its antioxidant and anti-inflammatory properties and for its ability to upregulate endothelial NO synthase (eNOS. RES was able to scavenge •OH/O2•− and peroxyl radicals, which can limit the lipid peroxidation processes. Moreover, in bovine aortic endothelial cells (BAEC under glucose-induced oxidative stress, RES restored the activity of dimethylargininedimethylaminohydrolase (DDAH, an enzyme that degrades an endogenous inhibitor of eNOS named asymmetric dimethylarginine (ADMA. Thus, RES could improve •NO availability and decrease the endothelial dysfunction observed in diabetes. Preclinical studies have made it possible to identify molecular targets (SIRT-1, AMPK, Nrf2, NFκB…; however, there are limited human clinical trials, and difficulties in the interpretation of results arise from the use of high-dose RES supplements in research studies, whereas low RES concentrations are present in red wine. The discussions on potential beneficial effects of RES in CVDs (atherosclerosis, hypertension, stroke, myocardial infarction, heart failure should compare the results of preclinical studies with those of clinical trials.

    The term chronic kidney disease-mineral bone disorder has been coined recently to highlight that the disturbed mineral and bone metabolism is a major contributor to vascular calcification and finally cardiovascular disease. This syndrome is characterized by clinical, biochemical and/or histological findings, i.e. i) biochemical alterations in the homeostasis of calcium, phosphate and their key player parathyroid hormone (PTH), Fibroblast growth factor-23 (FGF-23), klotho and vitamin-D, ii) the occurrence of vascular and/or soft tissue calcification, and iii) an abnormal bone structure and/or turnover. Apart from the combined and synergistic action of "traditional" and uremia-related risk factors, promoters and inhibitors of calcification have to be considered as well. This review will focus on the disturbed mineral metabolism as the triggering force behind distortion of vascular integrity and cardiovascular malfunction in CKD patients.

    T wave alternans (TWA) is the variation of the T-wave in electrocardiogram that is observed between periodic beats. TWA is one of the important precursors used to diagnose sudden cardiac death (SCD). Several clinical studies have tried to determine the significance of using TWA analysis to detect abnormalities that may lead to Ventricular Arrhythmias, as well as establish metrics to perform risk stratification for cardiovascular patients with prior cardiac episodes. The statistical significance of TWA in predicting ventricular arrhythmias has been established in patients across several diagnoses. Studies have also shown the significance of the predictive value of TWA analysis in post myocardial infarction patients, risk of SCD, congestive heart failure, ischemic cardiomyopathy, and Chagas disease.

    Abnormal protein aggregation or amyloid is the major cause ofmany neurodegenerative disorders. The present review focuses on the correlation between sequence and structure features of proteins related to the diseases and abnormal protein aggregation. Recent progress has improved our knowledge on understand-ing the mechanism of amyloid formation. We suggest a nucleation model for ordered protein aggregation, which can also explain pathogenesis mechanisms of these neurodegenerative diseases in vivo.

    Background and objective Atypical 'cardiac' chest pain (ACCP) is not usually caused by myocardial ischaemia. Current noninvasive investigations for these symptoms are not yet as accurate as invasive coronary angiography. The latest 64-row multi-detector computed tomography (MDCT) technology is non-invasive, has high specificity and negative predictive values for the detection of significant coronary disease. Our aim was to investigate if this modality can provide more information in the assessment of outpatients with ACCP in addition to established cardiovascular risk scores. Methods Seventy consecutive patients presenting to the outpatient clinic with ACCP underwent 64-row MDCT scan of the coronary arteries. They were categorized into low, medium or high risk groups based upon the Framingham and PROCAM scores. We defined a clinically abnormal MDCT scan as coronary stenosis =50% or calcium score >400 Agatston. Results Fifty-three (75.7%) patients did not have clinically abnormal scans. Framingham score classified 43 patients as low-risk while PROCAM classified 59 patients as low-risk. MDCT scans were abnormal for 18.6% and 22.0% of the respective low-risk group of patients. For patients with medium-to-high risk, 33.3% and 36.4% of Framingham and PROCAM patient groups respectively had abnormal MDCT scans. Conclusion MDCT adds valuable information in the assessment of patients with ACCP by identifying a significant proportion of patients categorized as low-risk to have underlying significant coronary stenosis and coronary calcification by established cardiovascular risk scores.

    Objectives Furthering our understanding of the relationship between amyloidosis (Aβ), neurodegeneration (ND), and cognition is imperative for early identification and early intervention of Alzheimer’s disease (AD). However, the subtle cognitive decline differentially associated with each biomarker-defined stage of preclinical AD has yet to be fully characterized. Recent work indicates that different components of memory performance (free and cued recall) may be differentially specific to memory decline in prodromal AD. We sought to examine the relationship between free and cued recall paradigms, in addition to global composites of memory, executive functioning, and processing speed in relation to stages of preclinical AD. Methods A total of 260 clinically normal (CN) older adults (CDR=0) from the Harvard Aging Brain study were grouped according to preclinical AD stages including Stage 0 (Aβ−/ND−), Stage 1 (Aβ+/ND−), Stage 2 (Aβ+/ND+), and suspected non-Alzheimer’s associated pathology (SNAP; Aβ−/ND+). General linear models controlling for age, sex, and education were used to assess for stage-based performance differences on cognitive composites of executive functioning, processing speed, and memory in addition to free and cued delayed recall on the Selective Reminding Test (SRT) and Memory Capacity Test (MCT). Results Global memory performance differed between preclinical stages with Stage 2 performing worse compared with Stage 0. When examining free and cued paradigms by memory test, only the MCT (and not the SRT) revealed group differences. More specifically, Stage 1 was associated with decrements in free recall compared with Stage 0 while Stage 2 was associated with decrements in both free and cued recall. There was a trend for the SNAP group to perform worse on free recall compared with Stage 0. Finally, there was no association between preclinical stage and global composites of executive functioning or processing speed. Conclusions Clinically

    2012-02-01

    Recent reports from needle exchange programmes and other public health initiatives have suggested growing use of anabolic steroids (AS) in the UK and other countries. Data indicate that AS use is not confined to body-builders or high-level sportsmen. Use has spread to professionals working in emergency services, casual fitness enthusiasts and subelite sportsmen and women. Although the precise health consequences of AS use is largely undefined, AS use represents a growing public health concern. Data regarding the consequences of AS use on cardiovascular health are limited to case studies and a modest number of small cohort studies. Numerous case studies have linked AS use with a variety of cardiovascular disease (CVD) events or endpoints, including myocardial infarction, stroke and death. Large-scale epidemiological studies to support these links are absent. Consequently, the impact of AS use upon known CVD risk factors has been studied in relatively small, case-series studies. Data relating AS use to elevated blood pressure, altered lipid profiles and ECG abnormalities have been reported, but are often limited in scope, and other studies have often produced equivocal outcomes. The use of AS has been linked to the appearance of concentric left ventricular hypertrophy as well as endothelial dysfunction but the data again remains controversial. The mechanisms responsible for the negative effect of AS on cardiovascular health are poorly understood, especially in humans. Possibilities include direct effects on myocytes and endothelial cells, reduced intracellular Ca2+ levels, increased release of apoptogenic factors, as well as increased collagen crosslinks between myocytes. New data relating AS use to cardiovascular health risks are emerging, as novel technologies are developed (especially in non-invasive imaging) that can assess physiological structure and function. Continued efforts to fully document the cardiovascular health consequences of AS use is important to

    Rho kinases (ROCKs) are the first and the best-characterized effectors of the small G-protein RhoA. In addition to their effect on actin organization, or through this effect, ROCKs have been found to regulate a wide range of fundamental cell functions such as contraction, motility, proliferation, and apoptosis. Abnormal activation of the RhoA/ROCK pathway has been observed in major cardiovascular disorders such as atherosclerosis, restenosis, hypertension, pulmonary hypertension, and cardiac hypertrophy. This review, based on recent molecular, cellular, and animal studies, focuses on the current understanding of ROCK signaling and its roles in cardiovascular physiology and pathophysiology.

    BACKGROUND:Correlations between the structural abnormalities of chromosome 1pter in nasopharyngeal carcinoma(NPC) and its tumorigenesis and clinical significance are still unclear. OBJECTIVE: To investigate the correlations between the structural abnormalities of chromosome 1pter in NPC and the tumorigenesis of NPC. DESIGN:A retrospective study was performed to the control group according to the diagnosis. SETTING and PARTICIPANTS: The experiment was collected and completed in Reaearch Department of Sun Yat-Sen Cancer Center.Biopsy specimens from the nasopharynx of 65 cases of pathologically confirmed primary NPC without any therapy in the Sun Yat-Sen Univrsity Cancer Center were collected between the year 1998 and 2000 to survey. INTERVENTION: After the purification of cancerous cells from NPC biopsies with many noncancerous lymphocytes, interphase fluorescent in situ hybridization(FISH) and PCR-LOH/MI analysis of the somatic alterations of chromosomes 1pter in 65 cases of NPC biopsies were performed by using 1pter-related probe, TelVysion 1p, and telomere-linked microsatellite polymorphism site, D1S243,respectively. MAIN TOUCOME MEASURES: The abnormalities such as chromosome deletion, amplification and microsatellite instabilities(MI) and their clinical implications were examined and investigated. RESULTS:The somatic alterations of chromosome 1pter of NPC were detected in 20 of 65 cases with NPC, 8 of which showed allelic deletion,7 amplification and 5 both simultaneously.In available 44 patients with clinical stages, 2 of the 4 NPC cases in the early clinical stage were proved to be aberrations in chromosome 1pter, whereas 30.0% (12/40) of NPC patients in advanced clinical stage showed somatic structural aberrations of chromosome 1pter(χ 2=0.0655,P >0.05).PCR-LOH/MI analysis indicated that, out of the matched 31 NPC biopsies,16 had detectable aberrations, including 13 microsatellite instability(MI),2 homozygous deletion(HD) and 1 loss of heterozygosity

    Coronary heart disease (CHD) represents a major global health burden. However, despite the well-known influence that dietary habits exert over the progression of this disease, there are no well-established and scientifically sound dietary approaches to prevent the onset of clinical outcomes in secondary prevention. The objective of the CORonary Diet Intervention with Olive oil and cardiovascular PREVention study (CORDIOPREV study, clinical trials number NCT00924937) is to compare the ability of a Mediterranean diet rich in virgin olive oil versus a low-fat diet to influence the composite incidence of cardiovascular events after 7 years in subjects with documented CHD at baseline. For this purpose, we enrolled 1,002 coronary patients from Spain. Baseline assessment (2009-2012) included detailed interviews and measurements to assess dietary, social, and biological variables. Results of baseline characteristics: The CORDIOPREV study in Spain describes a population with a high body mass index (37.2% overweight and 56.3% obesity) and with a median of low-density lipoprotein cholesterol of 88.5 mg/dL (70.6% of the patients having oil as compared with a low-fat diet on the incidence of CHD recurrence in a long-term follow-up study.

    Full Text Available Homeobox genes are essential for both the development of the blood and lymphatic vascular systems, as well as for their maintenance in the adult. Homeobox genes comprise an important family of transcription factors, which are characterised by a well conserved DNA binding motif; the homeodomain. The specificity of the homeodomain allows the transcription factor to bind to the promoter regions of batteries of target genes and thereby regulates their expression. Target genes identified for homeodomain proteins have been shown to control fundamental cell processes such as proliferation, differentiation and apoptosis. We and others have reported that homeobox genes are expressed in the placental vasculature, but our knowledge of their downstream target genes is limited. This review highlights the importance of studying the cellular and molecular mechanisms by which homeobox genes and their downstream targets may regulate important vascular cellular processes such as proliferation, migration, and endothelial tube formation, which are essential for placental vasculogenesis and angiogenesis. A better understanding of the molecular targets of homeobox genes may lead to new therapies for aberrant angiogenesis associated with clinically important pregnancy pathologies, including fetal growth restriction and preeclampsia.

    Severe psoriasis has been associated with increase cardiovascular mortality, due to a higher prevalence of traditional cardiovascular risk factors and premature atherosclerosis, as a consequence of its systemic inflammation. Recently, it has been estimated that severe psoriasis may confer an increased 6.2% on long-term risk of cardiovascular disease based on Framingham Risk Score, which can have practical implications in the treatment of cardiovascular risk factors and primary prevention of cardiovascular disease, as treatment guidelines account for the risk of cardiovascular disease in treatment goals. The aim of this study was to analyze the influence of the attributable risk of severe psoriasis on long-term risk of cardiovascular disease and its implication on the correct treatment of cardiovascular risk factors and primary prevention of cardiovascular disease on a real-world cohort of patients. One hundred severe psoriasis patients without psoriatic arthritis or previous cardiovascular disease were evaluated and it was found that more than half of the patients were reclassified to a higher cardiovascular risk category with important clinical implications on the correct management of their cardiovascular risk factors and primary prevention of cardiovascular disease, as a considerable proportion of patients with hypertension, hypercholesterolemia and coronary heart disease equivalent risk were not being correctly managed.

    Introduction. Secure airway for proper ventilation during anesthesia is one important component of a successful surgery. Endotracheal intubation is one of the most important methods in this context. Intubation method and used medication are considerably important in attenuating complications. This research aimed to investigate the impact of two different doses of dexmedetomidine in mitigating cardiovascular responses to endotracheal intubation in candidate cases supporting voluntary operation. Methods. The current research contained 90 cases in the range of 18 and 50 old, with ASA I,II supporting voluntary operation, who were randomly classified into three teams, each group consisting of 30 cases. The first set (A) got 0.5 μg/ kg dexmedetomidine, the second set (B) got 1 μg/ kg dexmedetomidine and the third set (C) got an equal volume of saline as placebo, 600 seconds earlier the initiation of anesthesia. Hemodynamic parameters were recorded at baseline (T0), then after the injection and the earlier initiation of anesthesia (T1), after the induction of anesthesia and before the endotracheal intubation (T2), promptly after tracheal intubation, 180, and 300 after endotracheal intubation (T4, T5). Data was analyzed and p endotracheal intubation compared to group C. There were no significant differences in hemodynamic factors among group A, B. Conclusion. Dexmedetomidine effectively and significantly attenuates cardiovascular and hemodynamic responses during endotracheal intubation. In addition, different doses of dexmedetomidine did not cause any significant distinct result in mitigating cardiovascular responses.

    Hair shaft disorders may lead to brittleness and uncombable hair. In general the hair feels dry and lusterless. Hair shaft abnormalities may occur as localized or generalized disorders. Genetic predisposition or exogenous factors are able to produce and maintain hair shaft abnormalities. In addition to an extensive history and physical examination the most important diagnostic examination to analyze a hair shaft problem is light microscopy. Therapy of hair shaft disorders should focus to the cause. In addition, minimizing traumatic influences to hair shafts, such as dry hair with an electric dryer, permanent waves and dyes is important. A short hair style is more suitable for such patients with hair shaft disorders.

    Full Text Available Chromosomal abnormalities are among the most common genetic causes of spermatogenic disruptions. Carriers of chromosomal abnormalities are at increased risk of infertility, miscarriage or birth of a child with unbalanced karyotype due to the production of unbalanced gametes. The natural selection against chromosomally abnormal sperm usually prevents fertilization with sperm barring in cases of serious chromosomal abnormalities. However, assisted reproductive technologies in general and intracytoplasmic sperm injection in particular, enable the transmission of chromosomal abnormalities to the progeny. Therefore, cytogenetic studies are important in patients with male factor infertility before assisted reproduction treatment. The purpose of the current study was to investigate the types and frequencies of chromosomal abnormalities in 724 patients with infertility and to estimate the risk of chromosomal abnormalities detection in subgroups of patients depending on the severity of spermatogenic disruption, aiming at identifying groups of patients in need of cytogenetic studies. Karyotype analysis was performed in 724 blood samples of men attending infertility clinic. Chromosomal preparation was performed by standard techniques. At least 20 GTG-banded metaphase plates with the resolution from 450 to 750 bands per haploid set were analysed in each case. When chromosomal mosaicism was suspected, this number was increased to 50. Abnormal karyotypes were observed in 48 (6.6% patients, including 67% of autosomal abnormalities and 33% of gonosomal abnormalities. Autosomal abnormalities were represented by structural rearrangements. Reciprocal translocations were the most common type of structural chromosomal abnormalities in the studied group, detected with the frequency of 2.6% (n = 19, followed by Robertsonian translocation, observed with the frequency of 1.2% (n = 9. The frequency of inversions was 0.6% (n = 4. Gonosomal abnormalities included 14 cases

    Introducción: Es importante evaluar el papel de los alimentos tipo «snacks» sobre el apetito. El objetivo de este trabajo fue evaluar la respuesta en términos de saciedad y el efecto sobre factores de riesgo cardiovascular de dos galletas diferentes. Material y Métodos: Se randomizaron 38 pacientes: grupo I (galleta enriquecida en FOS, n=19) y grupo II (galleta control, n=19). Antes de la intervención nutricional y tras un mes, a los pacientes se les valoró la saciedad con un test de prueba con 5 galletas. Resultados: Tras el test de prueba, el area bajo la curva del test de saciedad fue mayor con la galleta saciante que con la galleta control, detectándose el mismo resultado con el test trás 1 mes de ingerir las galletas. Analizando los diferentes tiempos, el score de saciedad mostró una puntuación superior en los tiempos 20 y 40 minutos frente al valor basal (tiempo 0) tras la ingesta de la galleta saciante, comparado con la galleta control. Los valores de saciedad en los tiempos (20 minutos y 40 minutos) fueron superiores que los que presentó la galleta control. Este resultado fue similar, al realizar el test tras 1 mes tomando la galleta saciante. Los resultados fueron similares al utilizar una escala visual de saciedad de 100 mm con 5 cuestiones. No se detectaron efectos sobre los factores de riesgo cardiovascular tras la intervención nutricional, ni sobre la ingesta dietética global. Conclusion: La galleta enriquecida en FOS produce mayores niveles de saciedad que la galleta control. Sin embargo no existieron efectos sobre los factores de riesgo cardiovascular ni la ingesta dietética global.

    The chronic inflammatory nature of psoriasis is also thought to predispose patients to other diseases with an inflammatory component, the most notable being cardiovascular and metabolic (cardiometabolite) disorders. This concept is supported by studies showing that psoriasis is associated with cardiovascular risk factors like diabetes, obesity, hypertension, dyslipidemia, smoking and diseases including MI. Given the increased prevalence of cardiovascular co morbidities in patients, dermatolog...

    Cardiovascular diseases are mainly caused by atherosclerosis, the development of which is highly dependent on our Western lifestyle. Slowing this pathology depends on the reduction of risk factors such as hypercholesterolemia, high blood pressure, smoking, lack of physical activity, excess weight and diabetes. Drug treatment exists and is very effective, but too often they treat the immediate abnormality such as diabetes, high blood pressure and hypercholesterolemia and not the underlying causes: poor eating habits, lack of physical activity and excess weight. These have a negative impact on endothelial function, oxidative stress, and can trigger inflammation, arrythmias and thrombosis. Cardiovascular prevention must therefore target sedentary lifestyle, excess weight, and favor low-calorie, low-salt food and Mediterranean diet. The way this diet works begins to be understood and goes beyond simple cardiovascular prevention. Therapeutic education holds a growing and complementary role in the Public Health system which should call upon the strengths of all healthcare professionals.

    Full Text Available Chronic hepatitis C virus (HCV infection is a systemic disease that leads to increased risks of cirrhosis and its complications, as well as extrahepatic disturbances, including immune-related disorders and metabolic alterations such as insulin resistance and steatosis. Recent accumulating evidence suggests that HCV infection can increase cardiovascular risk, and that viral eradication can improve cardiovascular outcomes in the clinical setting. These data are strengthened by evidence identifying potential mechanisms (indirectly linking HCV infection to vascular damage. However, the high prevalence of both HCV infection and cardiovascular alterations, as well as the presence of contrasting results not identifying any association between HCV infection and cardiovascular dysfunction, provides uncertainty about a direct association of HCV infection with cardiovascular risk. Further studies are needed to clarify definitively the role of HCV infection in cardiovascular alterations, as well as the impact of viral eradication on cardiovascular outcomes. These features are now more attractive, considering the availability of new, safe, and very effective interferon-free antiviral agents for the treatment of HCV infection. This review aims to discuss carefully available data on the relationship between HCV infection and cardiovascular risk.
