RESUMO

Boswellia sacra oleo gum resin (Burseraceae) commonly known as frankincense is traditionally used in many countries for its beneficial effect on male fertility. This study explores its effect on the male reproductive system after a 60-day repeated administration at two different doses to rats (in vivo) and on human Leydig cells (in vitro). The methanolic extract of B. sacra was analyzed for the presence of various constituents by preliminary phytochemical analysis and gas chromatography-mass spectrometry (GC-MS) while quantitative analysis of boswellic acids was done by high-performance liquid chromatography (HPLC). Administration of B. sacra extract to rats elevated the serum testosterone levels with an associated reduction in serum levels of FSH and LH. An increase in the activity of antioxidant enzymes, superoxide dismutase and catalase, was seen. A dose-dependent increase in the sperm count and sperm motility was also observed. The in vivo results were supported by changes in the expression of the Bcl-2 gene and caspase-3 gene in human Leydig cells in vitro. The results of this study support the traditional use of B. sacra to increase male fertility.

RESUMO

BACKGROUND & OBJECTIVES: Acute myocardial infarction (AMI) is characterized by irreparable and irreversible loss of cardiac myocytes. Despite major advances in the management of AMI, a large number of patients are left with reduced left ventricular ejection fraction (LVEF), which is a major determinant of short and long term morbidity and mortality. A review of 33 randomized control trials has shown varying improvement in left ventricular (LV) function in patients receiving stem cells compared to standard medical therapy. Most trials had small sample size and were underpowered. This phase III prospective, open labelled, randomized multicenteric trial was undertaken to evaluate the efficacy in improving the LVEF over a period of six months, after injecting a predefined dose of 5-10 × 10 [8] autologous mononuclear cells (MNC) by intra-coronary route, in patients, one to three weeks post ST elevation AMI, in addition to the standard medical therapy. METHODS: In this phase III prospective, multicentric trial 250 patients with AMI were included and randomized into stem cell therapy (SCT) and non SCT groups. All patients were followed up for six months. Patients with AMI having left ventricular ejection fraction (LVEF) of 20-50 per cent were included and were randomized to receive intracoronary stem cell infusion after successfully completing percutaneous coronary intervention (PCI). RESULTS: On intention-to-treat analysis the infusion of MNCs had no positive impact on LVEF improvement of ≥ 5 per cent. The improvement in LVEF after six months was 5.17 ± 8.90 per cent in non SCT group and 4.82 ± 10.32 per cent in SCT group. The adverse effects were comparable in both the groups. On post hoc analysis it was noted that the cell dose had a positive impact when infused in the dose of ≥ 5 X 10 [8] (n=71). This benefit was noted upto three weeks post AMI. There were 38 trial deviates in the SCT group which was a limitation of the study. INTERPRETATION & CONCLUSIONS: Infusion of stem cells was found to have no benefit in ST elevation AMI. However, the procedure was safe. A possible benefit was seen when the predefined cell dose was administered which was noted upto three weeks post AMI, but this was not significant and needs confirmation by larger trials.

RESUMO

Objectives: Retro walking or backward walking expends greater energy and places less stress on joints compared with forward walking at a similar speed. This study conducted in obese young men was primarily aimed at comparing the effects of backward walking with forward walking on adiponectin levels. The secondary aim was to describe the effects of concomitant factors, namely C-reactive protein, body mass index (BMI), waist to height ratio, and waist to hip ratio, on adiponectin levels in obese young men. Methods: In this randomized comparative study, 102 participants underwent either retro walking or forward walking treadmill training four times a week for 12 weeks before and after which adiponectin, C-reactive protein, BMI, waist to height ratio, and waist to hip ratio were measured. Comparison of the measured values before and after intervention and between the groups was done, and the influence of C-reactive protein, BMI, waist to height ratio, and waist to hip ratio on adiponectin levels was determined. Results: Adiponectin levels were significantly increased (p < 0.001) and C-reactive protein, BMI, waist to height ratio, and waist to hip ratio were significantly decreased (p ≤ 0.001) post-intervention. The participants who underwent retro walking training showed a significantly higher change in C-reactive protein levels, BMI, and waist to hip ratio compared to the forward walking group (p < 0.001). Adiponectin levels were influenced by BMI (p < 0.001). Conclusion: Retro walking training leads to a greater increase in adiponectin and reduction in C-reactive protein, BMI, waist to height ratio, and waist to hip ratio compared to forward walking, and adiponectin levels are influenced by BMI. Retro walking treadmill training can be preferentially used to decrease cardiovascular risk factors.

RESUMO

Background and Aims: Retro walking has been shown to acquire a greater metabolic cost, placing a higher cardiopulmonary demand on the body, when compared with forward walking at a similar speed. The aim of this study was to compare the effect of retro walking with that of forward walking on C-reactive protein (CRP) levels, body mass index (BMI) and blood pressure (BP) and to understand the influence of independent factors namely systolic blood pressure (SBP), diastolic blood pressure (DBP) and BMI on CRP in untrained overweight and obese young adults. Methods: This was a randomised controlled trial whereby 106 participants underwent either retro walking (n = 53) or forward walking (n = 53) treadmill training four times a week for 12 weeks before and after which CRP, BMI, and BP levels were measured. Comparison of the measured values before and after intervention and between the groups was done and influence of BMI and BP on CRP levels was determined. Results: Both groups recorded a significant decrease (p < 0.001) in CRP, BMI, and BP levels postintervention. The participants who underwent retro walking training showed a significantly (p < 0.001) higher decrease in all the outcomes as compared with the forward walking group. C-reactive protein levels were seen to be influenced by BMI and DBP. Conclusion: Retro-walking training leads to greater decrease in CRP, BMI, and BP when compared with forward walking, and CRP levels are influenced by BMI and DBP. Retro walking treadmill training can be used preferentially to bring about reduction in cardiovascular risk factors.

RESUMO

AIMS: There is increasing evidence of the role direction-dependent conduction plays in the arrhythmogenic interaction between ectopic triggers and abnormal atrial substrates. We thus sought to characterize direction-dependent conduction in chronically stretched atria. METHODS AND RESULTS: Twenty-four patients with chronic atrial stretch due to mitral stenosis and 24 reference patients with left-sided accessory pathways were studied. Multipolar catheters placed at the lateral right atrium, crista terminalis, and coronary sinus (CS) characterized direction-dependent conduction along linear catheters and across the crista terminalis. Bi-atrial electroanatomic maps were created in both sinus rhythm and an alternative wavefront direction by pacing from the distal CS. This allowed an assessment of conduction velocities, electrogram, and voltage characteristics during wavefronts propagating in different directions.  While differing wavefront directions caused changes in both chronic atrial stretch and reference patients (P< 0.001 for all), these direction-dependent changes were greater in chronic atrial stretch compared with reference patients, who exhibited greater slowing in conduction velocities (P= 0.09), prolongation of bi-atrial activation time (P= 0.04), increase in number (P< 0.001) and length (P< 0.001) of lines of conduction block, increase in fractionated electrograms (P< 0.001), and decrease in voltage (P= 0.08) during left-to-right compared with right-to-left atrial activation. These direction-dependent changes were associated with a greater propensity for chronically stretched atria to develop atrial fibrillation (P= 0.02). CONCLUSIONS: Atrial remodelling in chronic atrial stretch exacerbates physiological direction-dependent conduction characteristics. Our data suggest that the greater direction-dependent conduction seen in patients with chronic atrial stretch may promote arrhythmogenesis due to ectopic triggers from the left atrium.

RESUMO

Frankincense (Boswellia sacra Fluck.,) is traditionally used in the treatment of altered male fertile potential in several countries. This study evaluated the cytoprotective action of B. sacra oleo gum resin extract against cyclophosphamide (CP) induced testicular toxicity in rats (in-vivo) and lipopolysaccharide (LPS) induced cytotoxicity in human Leydig cells (in-vitro). The methanolic extract of B. sacra was standardized for the presence of different boswellic acids using high-performance liquid chromatography (HPLC) and volatile constituents in the extract were detected by gas chromatography-mass spectrometry (GC-MS). Two doses of B. sacra extract were used in the in-vivo study. The HPLC analysis showed that extract contains about 36% w/w of total boswellic acids and GC-MS analysis revealed the presence of another 71 different constituents. Administration of B. sacra extract to rats increased serum testosterone levels, antioxidant enzyme activities, and sperm count with improved sperm quality in a dose-dependent manner, when compared to CP treated animals. Boswellia sacra extract also protected the human Leydig cells against LPS-induced damage and increased the expression of the Bcl-2 gene along with a decrease in caspase-3 gene expression. The results of this study show that B. sacra extract has a protective effect on the male reproductive system.

RESUMO

BACKGROUND & OBJECTIVES: Methylenetetrahydrofolate reductase (MTHFR) is a critical enzyme in folate metabolism and involved in DNA synthesis, DNA repair and DNA methylation. The two common functional polymorphisms of MTHFR, 677 C-->T and 1298 A-->C have shown to impact several diseases including cancer. This case-control study was undertaken to analyse the association of the MTHFR gene polymorphisms 677 C-->T and 1298 A-->C and risk of colorectal cancer (CRC). METHODS: One hundred patients with a confirmed histopathologic diagnosis of CRC and 86 age and gender matched controls with no history of cancer were taken for this study. DNA was isolated from peripheral blood samples and the genotypes were determined by PCR-RFLP. The risk association was estimated by compounding odds ratio (OR) with 95 per cent confidence interval (CI). RESULTS: Genotype frequency of MTHFR 677 CC, CT and TT were 76.7, 22.1 and 1.16 per cent in controls, and 74, 25 and 1.0 per cent among patients. The 'T' allele frequency was 12.21 and 13.5 per cent in controls and patients respectively. The genotype frequency of MTHFR 1298 AA, AC, and CC were 25.6, 58.1 and 16.3 per cent for controls and 22, 70 and 8 per cent for patents respectively. The 'C' allele frequency for 1298 A-->C was 43.0 and 45.3 per cent respectively for controls and patients. The OR for 677 CT was 1.18 (95% CI 0.59-2.32, P = 0.642), OR for 1298 AC was 1.68 (95% CI 0.92-3.08, P = 0.092) and OR for 1298 CC was 0.45 (95% CI 0.18-1.12, P = 0.081). The OR for the combined heterozygous state (677 CT and 1298 AC) was 1.18 (95% CI 0.52-2.64, P =0.697). INTERPRETATION & CONCLUSION: The frequency of the MTHFR 677 TT genotype is rare as compared to 1298 CC genotype in the population studied. There was no association between 677 C-->T and 1298 A-->C polymorphisms and risk of CRC either individually or in combination. The homozygous state for 1298 A-->C polymorphism appears to slightly lower risk of CRC. This needs to be confirmed with a larger sample size.

RESUMO

AIMS: To characterize the atrial remodelling in mitral stenosis (MS). METHODS AND RESULTS: Twenty-four patients with severe MS undergoing commissurotomy and 24 controls were studied. Electrophysiological evaluation was performed in 12 patients in each group by positioning multi-electrode catheters in both atria to determine the following: effective refractory period (ERP) at 10 sites at 600 and 450 ms; conduction time; conduction delay at the crista terminalis (CT); and vulnerability for atrial fibrillation (AF). P-wave duration (PWD) was determined on the surface ECG. In the remaining 12 patients in each group, electroanatomic maps of both atria were created to determine conduction velocity and identify regions of low voltage and electrical silence. Patients with MS had larger left atria (LA) (P < 0.0001); prolonged PWD (P = 0.0007); prolonged ERP in both LA (P < 0.0001) and right atria (RA) (P < 0.0001); reduced conduction velocity in the LA (P = 0.009) and RA (P < 0.0001); greater number (P < 0.0001) and duration (P< 0.0001) of bipoles along the CT with delayed conduction; lower atrial voltage in the LA (P < 0.0001) and RA (P < 0.0001); and more frequent electrical scar (P = 0.001) compared with controls. Five of twelve with MS and none of the controls developed AF with extra-stimulus (P = 0.02). CONCLUSION: Atrial remodelling in MS is characterized by LA enlargement, loss of myocardium, and scarring associated with widespread and site-specific conduction abnormalities and no change or an increase in ERP. These abnormalities were associated with a heightened inducibility of AF.

RESUMO

Remethylation of homocysteine to methionine is dependent on an adequate supply of one or more of the B vitamins like folate, vitamin B(12) and vitamin B(6). Plasma total homocysteine (tHcy) is also influenced by genetic factors such as polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene. MTHFR is a flavo enzyme and a key player in folate metabolism and changes in its activity could modify the susceptibility to Acute Lymphoblastic Leukemia (ALL). In this case - control study we have examined the effect of riboflavin status as measured by erythrocyte glutathione reductase activation coefficient (EGRAC) on homocysteine levels along with vitamin B(12) and folate in pediatric ALL. Folate and B(12) levels were significantly lower among cases as compared to controls while EGRAC and tHcy did not differ significantly among the groups. The multivariate regression analysis revealed that in the ALL group EGRAC significantly influences tHcy levels suggesting that riboflavin availability may be a predictor of tHcy levels in patients with ALL. This finding may have implications for tHcy lowering therapy.

RESUMO

Folate and cobalamin (Vitamin B(12)) are two essential micronutrients involved in one-carbon metabolism, which affects heart disease, neural tube defects and cancer. Methylenetetrahydrofolate reductase, the key enzyme involved in one carbon metabolism produces methyl tetrahydrofolate from methylene tetrahydrofolate, which in turn donates methyl group to homocysteine to generate methionine. There exist two common low function polymorphic variants of the methylenetetrahydrofolate reductase gene involving nucleotides 677 C→T and 1298 A→C, which are associated with hyperhomocysteinemia. These polymorphisms are also linked with increased risk for certain cancers such as breast cancer and at the same time providing a protective effect on colorectal cancer. In this case control study, we have evaluated levels of folic acid, vitamin B(12) and homocysteine in patients with colorectal cancer. Folate and homocysteine levels did not differ significantly between the two groups; however an increasing trend was noticed with increase in homocysteine levels. Vitamin B(12) levels were increased in cases compared to control group.

RESUMO

BACKGROUND: There is widespread concern about radiation doses imparted to patients during cardiology procedures in the medical community. The current study intends to audit and optimize radiation dose to patients undergoing coronary angiography (CA) performed using two dedicated cardiovascular machines. MATERIALS AND METHODS: One hundred and forty nine patients who underwent CA are reported in this study. Dose auditing was done by implementing dose reduction strategies using spectral filters and by evaluating work practices of operators involved in performing CA. STATISTICAL ANALYSIS: A Student's 't' test was used to analyze the statistical significance. RESULTS AND CONCLUSION: The radiation dose imparted to patients was measured using dose area product (DAP) meter. The mean DAP values during CA before optimization was 55.86 Gy cm2 and after optimization was 27.71 Gy cm2. No ill-effects of radiation were reported for patients who underwent CA. Use of copper filtration may be recommended for procedures performed using cardiovascular machines.

RESUMO

BACKGROUND AND AIM OF THE STUDY: Patients with aortic stenosis (AS) exhibit increased platelet aggregability, and thrombus formation has been documented on calcific and severely stenosed valves. Isolated porcine and canine aortic valves (AV) release nitric oxide (NO) and prostacyclin, which exert local antithrombotic effects; to date, this has not been studied in humans. In the present study the possible interaction of AV tissue with platelet aggregation was examined, using fragments of AV obtained from patients with AS and aortic regurgitation (AR). METHODS: Fragments of AV tissue, excised from patients undergoing AV replacement, were co-incubated with blood samples obtained from normal subjects. The direct effects of valve tissue from patients with AS (n = 14) or with predominant AR (n = 13) on ADP-induced platelet aggregation and intraplatelet cGMP and cAMP content were compared. RESULTS: In whole blood, non-calcified AV fragments from AR patients inhibited platelet aggregation by 57 +/- 6% (p < 0.01); in platelet-rich plasma results were analogous. In order to determine whether this anti-aggregatory effect could be attributed to the valvular release of NO or prostacyclin, intraplatelet cGMP and cAMP formation was assessed, respectively. While there were no significant changes in cGMP content, cAMP increased by 26 +/- 4% (p < 0.02). Both, anti-aggregatory and cAMP-stimulating effects were similar to those produced by 10 nM prostaglandin E1, a prostacyclin mimetic. Fragments from stenotic valves did not inhibit aggregation and did not affect cGMP or cAMP. Furthermore, fragments from heavily calcified regions potentiated aggregation and, in some cases, induced spontaneous aggregation. CONCLUSION: Minimally calcified aortic valves (i.e., AR) and, therefore, presumably also normal valves, exert anti-aggregatory effects, most likely via prostacyclin release. AS is associated with a loss of this effect, thus potentially contributing to thrombotic risk.

RESUMO

The over-the-wire double balloon technique (DBT) of balloon mitral valvuloplasty (BMV) has been decreasingly used in recent years because of its relative complexity and potential for left ventricular perforation. We attempted to make over-the-wire BMV simpler and safer by developing: (a) a single balloon technique (SBT) using a rapidly inflating, over-the-wire, cylindrical balloon having abrupt distal taper and short blunt tip to prevent left ventricular perforation, and (b) an alternative jugular approach to reduce technical difficulty in patients with cardiac anatomic distortion. SBT-BMV was evaluated over seven years in 1,407 consecutive patients (femoral approach: 1,277 patients, jugular approach: 130 patients), and compared with 954 patients who underwent DBT-BMV earlier at the same center. Results of SBT-BMV were comparable to those of DBT-BMV: optimal outcomes (91.0% versus 87.8%), fluoroscopy time (12.4 +/- 6.8 minutes versus 17.6 +/- 7.2 minutes), significant right heart oxygen step-up (4.8% versus 10.7%), and major complication rates (3.7% versus 5.6%) were significantly better with SBT-BMV; whereas mean post-BMV mitral valve area (1.92 +/- 0.31 cm2 versus 2.03 +/- 0.42 cm2), and post-BMV hemodynamic parameters were inferior with SBT-BMV. Balloon-related left ventricular perforation did not occur in SBT-BMV. Fluoroscopy time in jugular approach SBT-BMV (9.0 +/- 4.2 minutes) was significantly lower than in the femoral approach SBT-BMV (12.4 +/- 6.8 minutes) despite cardiac anatomic distortion. SBT-BMV reduced procedural costs considerably. SBT-BMV was effective, safe, technically simple and economical; it was comparable to, and overcame several limitations of DBT-BMV.

RESUMO

BACKGROUND: Cardiac resynchronization therapy has emerged as a new therapeutic modality for patients with congestive cardiac failure and associated intraventricular conduction delay. The purpose of this study was to find out what proportion of Indian patients with congestive heart failure may be candidates for cardiac resynchronization therapy based on electrocardiographic characteristics. METHODS AND RESULTS: One hundred twenty-one consecutive patients with congestive cardiac failure due to various etiologies whose left ventricular ejection fraction was less than 40% were included in the study. Standard 12-lead electrocardiogram was recorded in all the patients, and various parameters (rhythm, conduction, QRS axis, chamber enlargement, chamber hypertrophy, and the presence of Q waves) were analyzed. The study population comprised 82 male (67.8%) and 39 female (32.2%) patients with a mean age of 53 +/- 13 years. Thirty-nine patients (32.2%) had NYHA class I-II symptoms, and 82 (67.8%) had NYHA class III-IV symptoms. The mean QRS duration was 111 +/- 27 ms. Bundle branch block was seen in 43 patients (35.5%), of whom 30 (24.8%) had left bundle branch block, and 13 (10.7%) had right bundle branch block. Of the 30 patients who had left bundle branch block, 19 (15.7%) had a QRS duration of between 120 and 149 ms, and 11 (9%) had a QRS duration > or = 150 ms. In the latter group, 7 patients (5.8%) were in NYHA classes III and IV. As the clinical severity of heart failure increased, the mean QRS duration also increased, but this increment was not statistically significant. CONCLUSIONS: Based on our data, it can be estimated that of the patients with heart failure who attend a tertiary care center, 2 5% of patients present with left bundle branch block. If we use the criteria for NYHA class III and IV congestive cardiac failure with QRS duration of > or = 150 ms in patients with left bundle branch block, 6% of patients are likely to need cardiac resynchronization therapy.

RESUMO

BACKGROUND: This study was undertaken to determine the prevalence of coronary artery disease in patients with rheumatic heart disease undergoing valve surgery. METHODS AND RESULTS: Consecutive patients with rheumatic heart disease (n=376) who were above the age of 40 years, and scheduled for valve surgery underwent diagnostic coronary angiogram to delineate coronary arteries. The patients were divided into three groups based on valve involvement (mitral valve, aortic valve, and combined aortic and mitral valve). Significant coronary artery disease was considered to be present if one or more coronaries showed 50% or more luminal stenosis. There were 287 (76.3%) males and 89 (23.7%) females. The mean age of the study population was 51.2+/-8.2 years. Eighty-nine (23.8%) patients had typical chest pain, 116 (30.6%) patients had atypical chest pain and 171 (45.5%) patients had no chest pain. Hypertension was noted in 88 (23.4%) patients, 65 (17.3%) patients had diabetes, 98 (26.1%) patients were smoker, and 66 (17.6%) patients had dyslipidemia, and 15 (4.0%) patients gave past history of myocardial infarction. Of the total 376 patients, 46 (12.2%) patients were found to have significant coronary artery disease. In patients with mitral vale disease the prevalence was 13.5% (13/96), while it was 15.3% (19/124) in patients with aortic valve disease and 9% (14/156) in those with combined mitral and aortic valve disease. CONCLUSIONS: Our results suggest that the overall prevalence of coronary artery disease in a group of patients with rheumatic heart disease undergoing valve surgery in the current era is 12.2%. This prevalence is much lower than the figures reported earlier in the Western literature.

RESUMO

Post Thoracotomy Pain Syndrome (PTPS) is defined as pain that occurs or persists in the area of the thoracotomy incision for at least 2 months following the initial procedure.  The true incidence of PTPS is hard to define as literature reports a wide range of occurrence from 5% to 90%.  Thoracotomy is associated with a high risk of severe chronic postoperative pain.  Presenting symptoms include both neuropathic pain in the area of the incision, as well as myofascial pain commonly in the ipsilateral scapula and shoulder.  Pain management can be challenging in these patients.  Multiple treatments have been described including conservative treatments with oral nonsteroidal anti-inflammatory drugs (NSAIDs); topically applied, peripherally acting drugs; neuromodulating agents; physical therapy; transcutaneous electrical nerve stimulation as well as more invasive treatments including intercostal nerve blocks, trigger point steroid injections, epidural steroid injections, radiofrequency nerve ablation, cryoablation, and one case report of spinal cord stimulation.  Unfortunately, a portion of these patients will have persistent pain in spite of multiple treatment modalities, and in some cases will experience worsening of pain. This case report describes the novel utility and complete resolution of symptoms with spinal cord stimulation (SCS) in treatment of a patient with persistent PTPS. In the operating room, a percutaneous octet electrode lead was placed using sterile technique under fluoroscopic guidance and loss-of-resistance technique.  The octet electrode lead was subsequently advanced with the aid of fluoroscopy to the level of the T3 superior endplate just right of midline.  The patient's pain distribution was captured optimally with stimulation at this level.  With the assistance of a neurosurgeon, the lead was anchored, tunneled, and connected to a generator, which was implanted over the right iliac crest.  The patient tolerated the procedure well with no complications. We report the successful use of SCS as well as complete resolution of symptoms at 4 months follow-up, in a patient with persistent PTPS, which was resistant to other modalities. In conclusion, studies designed to evaluate the effectiveness of SCS for PTPS may be warranted.
