Effects of a short Cardiovascular Rehabilitation program in Hypertensive subjects: A Pilot Study
Published on: 2nd May, 2017
OCLC Number/Unique Identifier: 7286350945
Systemic arterial hypertension (SAH) is considered an important risk factor for the development of cardiovascular diseases. The aim of the present study was to verify the effects of a short cardiovascular rehabilitation program (CR) in hypertensive subjects. The clinical pilot study involved a sample composed of 11 hypertensive subjects. It was evaluated the weight, height, body mass index (BMI), waist and hip circumference, waist hip ratio, systolic blood pressure (SBP), diastolic blood pressure (DBP) and six-minute walk test (6-MWT) before and after CR. CR was performed twice a week for 60 minutes. The results shown that after CR occurred a reduction of waist circumference (99.86±8.7 to 95.2±8.6 cm, p=0.0002) and hip circumference (110.18±14.75 to 105.00±12.7 cm p=0.01) values. About the mean distance walked in the 6-MWT there was an increase after the CR program (335.9±123.5 m to 554.56±87.9 m, p=0.000). In conclusion, the results suggest that a short CR is an effective for the treatment of hypertensive subjects. After 16 CR sessions, functional and musculoskeletal capacity was improved, evaluated by 6-MWT. Furthermore, the short CR program decreased waist and hip circumferences, being an important option for these subjects. Although. There were no changes in baseline blood pressure levels.
Chondrogenic re-differentiation potential of chondrocytes after monolayer culture: Comparison between osteoarthritis and young adult patients
Published on: 27th March, 2019
OCLC Number/Unique Identifier: 8049578277
Purpose: Monolayer passage of chondrocytes results in dramatic phenotypic changes. This “de-differentiation” is expected to restore the chondrogenic properties such as “re-differentiation” in autologous chondrocyte implantation (ACI). The purpose of this study was to compare the chondrogenic re-differentiation potential of chondrocytes, from osteoarthritis (OA) patients and young adult patients, after monolayer culture.
Methods: Chondrocytes from five old patients with knee OA (OAC) and five young patients with recurrent shoulder dislocation (non-OAC) were used. The chondrocytes from passages 1 to 3 were analyzed for the expression of cell surface markers (CD73, CD90, CD105, and CD44) by flow cytometric analysis. Chondrocytes of passage 4 were cultured as pellets for re-differentiation and evaluated histologically. Real-time PCR were performed to measure the chondrogenic related genes transcriptional levels.
Results: OAC and non-OAC had comparable positive ratios for CD44, CD73, CD90, and CD105. The expression of CD105 was upregulated from passage 1 to passage 3 in OAC, and it increased at the same level as in non-OAC during passage 2 and 3. The expression of COL2 decreased from passage 1 to passage 3 in both the groups. There were no statistical differences in the Bern Scores between OAC and non-OAC.
Conclusion: The chondrocytes from OA patients and young adult patients had chondrogenic re-differentiation potential. The changes in cell surface markers and chondrogenic related genes showed similarity for both the groups. Our findings suggest that OAC can become the cell source for ACI.
Head impact exposure comparison between male and female amateur rugby league participants measured with an instrumented patch
Published on: 29th April, 2019
OCLC Number/Unique Identifier: 8163924025
Background: Epidemiological studies report that females experience greater rates of concussion when compared with males. Biomechanical factors may result in greater post-impact head velocities and accelerations for a given force for females when compared with males.
Purpose: To quantify the magnitude, frequency, duration and distribution of impacts to the head and body in rugby league match activities for females versus males.
Design: Prospective descriptive epidemiological study.
Methods: 21 female and 35 male amateur rugby league players wore wireless impact measuring devices (X2Biosystems; xPatch) behind their right ear over the mastoid process during match participation across a single season. All impact data were collected and downloaded for further analysis.
Results: Male amateur rugby league players experienced more head impacts than female amateur rugby league players (470 ±208 vs. 184 ±18; t(12)=-3.7; p=0.0028; d=1.94) per-match over the duration of the study. Male amateur rugby league players recorded a higher median resultant Peak Linear Acceleration (PLA(g)) (15.4 vs. 14.6 g; F(824,834)=51.6; p<0.0001; t(1658)=-3.3; p=0.0012; d=0.10) but a lower median resultant Peak Rotational Acceleration (PRA(rad/s2) (2,802.3 vs. 2,886.3 rad/s2; F(831,827)=3.1; p<0.0001; t(1658)=5.7; p<0.0001; d=0.13) when compared with female amateur rugby league players
Conclusion: Females recorded lower median values for PLA(g) and Head Impact Telemetry severity profile (HITSP) for all positional groups but had a higher PRA(rad/s2) for Hit-up Forwards (HUF) and Outside Backs (OSB’s) when compared with male HUF and OSB’s. Females also recorded more impacts to the side of the head (48% vs. 42%) and had a higher 95th percentile resultant PRA(rad/s2) (12,015 vs. 9,523 rad/s2) to the top of the head when compared with male rugby league players.
The effect of a European-based exercise program upon the health-related physical fitness of individuals with intellectual disabilities: The alive and kicking perspective
Published on: 24th December, 2019
OCLC Number/Unique Identifier: 8505524065
The present study examined the effect of the European-Based ‘Alive and Kicking’ exercise program on the health-related physical fitness of individuals with (Experimental Group: EG) and without (Control Group: CG) (Intellectual Disability: ID). The Self-Determination Theory: SDT, guided both the 6-month preparatory phase and the 9-month exercise program, which was conducted in five separate European countries (Cyprus, France, Greece, Portugal and Spain). The total sample (n = 200, 54% males and 46% females) comprised of 168 individuals with ID (age: 26.54 years, + 7.78) and 32 individuals without ID (age: 25.81 years, + 8.73) respectively. The statistical analyses revealed that the ID group’s performance (EG) improved significantly in a range of health-related physical fitness variables (sit & reach, pushups, sit ups, long jump, ½ mile walk/ run). In turn, the participants from the CG improved mainly in muscular endurance (sit ups and pushups). The results are discussed in accordance with SDT and the dairies kept from the staff involved (coaches and psychologists) during the 9–month intervention. The present findings, although subjective to certain limitations, are encouraging, given the large-scale, real-world nature of the research design, and provide evidence supporting the integration of theoretical strategies enhancing motivation into traditional coaching programs for individuals with ID.
An observational study of the occurrence of anxiety, depression and self-reported quality of life 2 years after myocardial infarction
Published on: 17th October, 2018
OCLC Number/Unique Identifier: 7893782705
Background: Patients with myocardial infarction (MI) often experience anxiety, depression and poor quality of life (QoL) compared with a normative population. Mood disturbances and QoL have been extensively investigated, but only a few studies have examined the long-term effects of MI on these complex phenomena.
Aims: To examine the levels and associated predictors of anxiety, depression, and QoL in patients 2 years after MI.
Methods: This was a single center, observational study of patients with MI (n=377, 22% women, median age 66 years). Two years after MI (2012-2014), the patients were asked to answer the Hospital Anxiety and Depression Scale (HADS) and EuroQol 5-dimension (EQ-5D-3L) questionnaires.
Results: Most patients experienced neither anxiety (87%, 95% confidence interval [CI]: 83-90%) nor depression (94%, 95% CI: 92-97%) 2 years post-MI. Elderly patients experienced more depression than younger patients (p=0.003) and women had higher anxiety levels than men (p=0.009).
Most patients had “no problems” with any of the EQ-5D-3L dimensions (72-98%), but 48% (95% CI: 43%-53%) self-reported at least “some problems” with pain/discomfort. In a multiple logistic regression model (EQ-5D-3L) higher age (p<0.001) and female sex (p<0.001) were associated with more pain/discomfort. Female sex (p=0.047) and prior MI (p=0.038) were associated with anxiety/depression. History of heart failure was associated with worse mobility (p=0.005) and problems with usual activities (p=0.006). The median total health status of the patients (EQ-VAS) was 78 (95% CI: 75-80)
The effect of anemia on serum hepcidin levels in patients with heart failure
Published on: 17th October, 2019
OCLC Number/Unique Identifier: 8303641326
Background: Anemia is an accelerating problem among patients with heart failure (HF) and its presence is associated with more symptoms. In this study, we investigated whether anemia in heart failure was related to hepcidin concentration.
Methods: 50 patients with heart failure and 20 healthy subjects with no history of a chronic illness including heart failure as control group, were included in the study. Heart failure was verified by echocardiography in each subject and patients were defined as ones with reduced ejection fraction (HFrEF) if EF ≤ 40% and with preserved ejection fraction (HFpEF) if EF 40% - 50%. Blood samples were taken from all patients after 10-12 hours fasting. Anemia assessment was performed according to World Health Organization (WHO) criterias.
Results: There was a positive correlation between hepcidin concentration and urea, ferritin, hemoglobin, hematocrite, C-reactive protein (p < 0,05). Hepcidin concentrations of anemic heart failure patients were significantly lower than the non-anemic heart failure patients (p < 0,05).
Conclusion: We found that serum hepcidin concentration in anemic patients with heart failure was lower than in heart failure patients without anemia. We believe that iron defiency occurs as a result of inflammatory process in heart failure and therefore hepcidin concentrations decrease as a response. However, long-term follow up studies are needed.
Hemoptysis after subclavian vein puncture for pacemaker implantation: A case report
Published on: 15th November, 2019
OCLC Number/Unique Identifier: 8330425842
Background: Subclavian venous access for pacemaker lead insertion is a common procedure and is normally considered safe in the hands of an expert. However, subclavian venepuncture is not without complications, starting from mild subcutaneous hematoma to pneumothorax. We here present a case of hemoptysis occurring after difficult subclavian vein puncture, which subsequently improved on conservative management only.
Case Summary: A 65-year-old gentleman, post aortic valve replacement had persistent high-grade AV block and was taken up for a dual chamber pacemaker implantation. Immediately following venous access, he had a bout of hemoptysis, which recovered on its own. Post procedure chest x-ray was suggestive of alveolar hemorrhage which cleared gradually in next three-four days.
Discussion: Post subclavian venepuncture hemoptysis is known; but it is a rare complication, arising either because of lung parenchyma injury or arterial injury. This is mostly benign and improves on conservative management only; however rarely it may be massive and life threatening where transcatheter arterial embolization may be required.
Clinical relevance linked to echocardiography diagnosis in Bland, White and Garland syndrome
Published on: 6th March, 2020
OCLC Number/Unique Identifier: 8560715071
Introduction: Bland, White and Garland syndrome is a coronary anomaly with high mortality without treatment. Its clinical presentation is varied which makes epidemiological documentation difficult. Echocardiography is a useful non-invasive tool for diagnosis.
Objective: To determine the echocardiographic variables that lead to the diagnosis of Bland, White and Garland syndrome and their clinical relevance.
Material: Observational, prospective and cross-sectional study in 31 patients of the “William Soler” Pediatric Cardiocenter, from 2005 to 2018. To check the association of echocardiographic variables with the diagnosis of Bland, White and Garland syndrome, an effectiveness study was carried out that included the analysis of the incidence of echocardiographic variables that lead to the diagnosis of this entity. The clinical relevance was estimated according to the minimum importance limit. The statistical validation of the research results adopted a significance level of less than 5% (p < 0.05).
Results: The variables that facilitate the echocardiographic diagnosis of Bland, White and Garland syndrome were the echocardiographic visualization of the anomalous connection and the reversed flow in the anomalous left coronary artery. These echocardiographic measures have clinical relevance according to the quantification of risk estimators (incidence) the echocardiographic visualization of the anomalous connection, RR 39.00 and the reversed flow in the anomalous coronary artery, RR 26.31. LIM´s calculation value amounted to 6.31 and coincided with the risk estimators (incidence).
Conclusion: The echocardiographic visualization of the anomalous origin of the left coronary artery from the pulmonary arterial trunk and the detection of the local intracoronary reversed flow instituted as factors to be considered for the effective diagnosis of the disease. The documentation of the diagnostic aspects of the syndrome through echocardiography contains high statistical value and clinical relevance.
Effects of highest dose of sacubitril/valsartan association compared to lower doses on mortality and ventricular arrhythmias
Published on: 24th April, 2020
OCLC Number/Unique Identifier: 8588720714
Background: Sudden cardiac death is a major healthcare issue in reduced ejection fraction heart failure (HFrEF) patients. Recently, the new association of sacubitril/valsartan showed a reduction of both ventricular arrhythmias (VA) and mortality even at low dose compared to enalapril in HF patients. The purpose of our study was to assess whether the highest dose of sacubitril/valsartan compared to lower doses may improve the rate of death and VA in a population of patients with HFrEF and with an implantable cardiac defibrillator (ICD).
Methods: 104 HF patients with reduced EF under sacubitril/valsartan with an ICD were divided in 2 groups: the first one with the lower doses of sacubitril/valsartan (24/26 mg or 49 mg/51 mg twice daily) and the second with the maximal dose (97mg/103mg twice daily). The primary outcome was a composite of death or appropriate ICD therapy for VA.
Results: After a median follow-up of 14 months, 39 patients were treated with lower doses and 65 patients with the highest dose. Patients from the lower doses group were older (70 [60-80] vs. 66 [60-70]; p = 0,03), more symptomatic at initiation (NYHA 3: 44% vs. 19%; p < 0,01) and more often in atrial fibrillation (31% vs. 12%; p = 0,04). The primary composite endpoint occurred in 14 patients (36%) in the low doses group versus 7 patients (11%) in high dose group (p < 0,01). This difference was particularly observed in the subgroup of patients with ischemic cardiomyopathy. In a multivariable analysis, the higher dose was independently associated with the primary outcome with an HR = 2,934 [IC 95% 1,147 – 7,504]; p = 0,03. Kaplan-Meier curve showed an early effect of the highest dose of sacubitril/valsartan association.
Conclusion: Patients with HFrEF under the highest dose of sacubitril/valsartan showed better clinical outcomes with a decrease of both mortality or appropriated ICD therapies related to ventricular arrhythmias.
Our experience with single patch repair of complete atrioventricular septal defects
Published on: 2nd May, 2020
OCLC Number/Unique Identifier: 8588716552
Background: Various surgical methods have been utilized in the management of complete atrioventricular septal defects (CAVSD). Early intervention and achievement of a competent left atrioventricular valve are the key factors for successful treatment.
Methods: A total of 66 patients with complete atrioventricular septal defect have been operated in a tertiary care center. Patient group consisted of 28 males and 38 females with an average age of 6.2 ± 3.3 months. Ventricular and atrial defects were repaired generally with single-patch technique using autogenous pericardium.
Results: Preoperative catheterization and angiography was performed in 41 patients. Single patch and modified single patch techniques were preferred in 57 and 9 patients respectively. The average duration for respiratory support, intensive care unit stay and discharge from hospital were 36 ± 49.3 hours, 4.1 ± 1.9 days, and 10.1 ± 3.3 days respectively. In the left atrioventricular valve mild, moderate and severe regurgitation were detected in 44 (66.6%), 17 (25.7%) and 2 (3%) patients postoperatively. No regurgitation was determined in 3 patients (4.5%). Two cases ended up with mortality (3%).
Conclusion: Single patch repair technique can provide satisfactory surgical outcomes in patients with complete atrioventricular septal defect.
Prognosis of peripartum cardiomyopathy in sub-Saharan Africa (Burkina Faso South-West PPCM register)
Published on: 19th May, 2020
OCLC Number/Unique Identifier: 8605481207
Peripartum cardiomyopathy is one of the curable cardiomyopathy. It’s a severe and frequent disease arising among women of childbearing age. Its evolution in the long-term among some patients leads to chronic heart failure. Our study aims to determine from a prospective cohort, the factors associated with the non-recovery of myocardial function upon 12 months of diagnosis. Sociodemographic, clinical and echocardiographic data were collected at the time of diagnosis and then in months 3, 6 and 12. The outcome was the non-recovery of myocardial function at one year, defined by a left ventricular ejection fraction (LVEF) below 50%. 60 patients were analyzed after 12 months of follow-up. Mortality was about 13.3% and recovery rate of myocardial function reached 42.3%. After logistic regression, delay diagnosis and observance were the factors related to non- recovery of myocardial function.
Long-term results for post-interventional systemic heparinization following angioplasty of peripheral vessels
Published on: 15th June, 2020
OCLC Number/Unique Identifier: 8612480354
Objective: The long-term outcome of percutaneous transluminal angioplasties is mainly determined by restenoses, either by progression of the underlying disease or by intimal hyperplasia. Pharmacological substances on the one hand and the implantation of stents on the other have been developed with the intention of preventing precisely this complication. While patients are treated after PTA of peripheral vessels with different low-molecular-weight heparins, the indication for stent implantation is determined individually rather by experience. The aim of this study was to determine gender-specific risk factors of long-term outcome after percutaneous transluminal angioplasty (PTA) of peripheral vessels with or without stentimplantation.
Methods: In the present study, we examined the long-term results of percutaneous transluminal angioplasty (PTA) of peripheral vessels. Between 2007 and 2017, in total, 3,276 patients underwent PTA with or without stent implantation in our clinic. All patients were treated postinterventionally for 48 hours with 25,000 IU heparin (Unfractionated Heparin (UFH), heparinsodium-Braun, 25,000 I.E./5 ml, 2 ml/h) monitored by the partial thromboplastin time and subsequently underwent a control investigation every 6 months. The endpoint of the study was determination of symptomatic stenosis larger than 50% that required reintervention.
Results: 239 (68.2% with mean age 68.02 years) male patients and 111 female patients (31.71% with mean age 62.92 years) were evaluated with complete follow-up. A total of 470 PTAs were performed on male patients and 213 on female patients in multiple interventions. The majority of patients at the time of treatment were in stage IIb according to the classification of Fontaine (81.6% of male patients and 68% of females). In our sample, peripheral arterial disease stage III and IV according to Fontaine classification occurred twice as frequently in female patients as in male patients (stage III in 12.6% in female versus 6.1% in male, and stage IV in 18% in female versus 8.9% in males). In both groups, the femoral superficialis artery was most frequently dilated (64 cases, 30% in female and 155 cases, 32.9% in male), followed by the iliacal communis artery (46 cases in female and 99 cases in male, both with 21.5%). A balloon angioplasty of the tibialis anterior and posterior arteries was performed twice as frequently in female patients as in male patients (28 cases with 13.1% of tibialis ant. artery in female versus 32 cases with 6.8% in male patients, and in 17 cases with 7.9% of tibialis post. artery in female versus 16 cases with 3.4% in male patients). In this study, without consideration of gender, patency rates of 79% after 2.5 years, 67% after 5 years, 49% after 7.5 years and 37% after 10 years were determined for PTA without stent implantation. Between the 7th and 10th year in follow-up, the cumulative patency rates for stent implantation was 49%, whereas it was 31% for PTA alone. The results of this study show that the stent assisted PTA`s of comm. artery and external iliacal artery are significantly independent of risk factors better than the femoral vessels, and these in female patients better than in male patients. Male patients do not benefit significantly from stent implantation in the long term. As the COXI and II regression analyses show, gender-linked results are most evident for renal insufficiency and diabetes mellitus, and less pronounced also for the number of open lower leg vessels.
Conclusion: Under consideration of gender and risk factors, while male patients with diabetes mellitus, renal insufficiency and/or poor run-off did not benefit from stent implantation in the long-term, female patients with similar risk factors showed higher patency rates after stent therapy. In addition, the long-term results after PTA of femoral superficialis artery and poplitea artery are significantly worse than PTA of the pelvic vessels in both genders.
Femoral venous closure: A single-centre retrospective analysis in real world all comers with MynxGrip® vascular closure device
Published on: 18th June, 2020
OCLC Number/Unique Identifier: 8628667812
Background: Vascular closure devices (VCD) are routinely used to achieve haemostasis following percutaneous arterial procedures. The extravascular polyethylene-glycol based MynxGrip® device (Cardinal Health) received FDA approval for use in the closure of femoral veins, but so far limited data is available on its use, especially with concomitant use of anticoagulants.
Method: This is a retrospective analysis of data from a single-centre on the effectiveness and complication rates following the use of the MynxGrip® device for femoral venous closure in patients undergoing diagnostic/interventional (temporary pacing during balloon aortic valvuloplasty, or electrophysiology) procedures utilising 5-7F sheaths.
Results: 85 patients (mean age 74 years) underwent femoral venous closure with the MynxGrip® device. 51.8% were male. The rate of concomitant anticoagulant or antiplatelet use was 52.9%. Device deployment was 100% successful with full haemostasis in all cases. There were no major vascular complications (bleeding, thrombosis, or infections). There was one case of a minor small venous hematoma which did not require treatment. The mean length of stay was less than 1 day (67.1% patients discharged the same day) and overnight stay only indicated by interventional procedure.
Conclusion: These data support safety and efficacy of the MynxGrip® device for femoral venous closure with same-day discharge, even with concomitant aggressive antiplatelet and anticoagulant use. It has the potential for use in other large bore venous access sites.
Antibiotic induced changes to mitochondria result in potential contributions to carcinogenesis, heart pathologies, other medical conditions and ecosystem risks
Published on: 2nd October, 2020
OCLC Number/Unique Identifier: 8689024240
With the discovery by Calghatgi (2013) that three common antibiotics (Abs) increased mitochondrial reactive oxygen (ROS) and lipid peroxide (LP) and depleted their natural absorbant glutathione led me to investigate further the potential impacts of these genotoxic substances on carcinogenesis. The range of impacts on mitochondria and cellular DNA varied by antibiotic to those consistent with known prior contributions to carcinogenesis. Specific cancers probably increased by these changes were HCC, RCC (KCC), CRC, cancer of the esophagus. Tumor suppressor gene mutations resulting from LP were noteworthy in this regard and mutations induced in CRC were consistent with those found in carcinogenesis of CRC. In addition depression of short chain fatty acids in microbiomes were found which depress the immune system increasing risk of all cancers. Many cancers were increased according to epidemiological studies linking Abs with elevated odds ratios, with one concern in particular, fatal breast cancer. The impact of loss of functionality of the mitochondria was also linked to depression of the citric acid cycle and therefore ATP which deflected metabolism to glycolysis, the Warburg mechanism also increasing risk of all cancers, favoured by cancer cells. In conclusion, some portion of many cancer types are probably increased in likelihood by number, type and frequency of Abs treatment and chronic residue exposure which varies from individual to individual. This led me to propose a three pronged carcinogenesis mechanism for Abs. 1. Cancer critical mutations 2. Immune depression 3. loss of mitochondrial functionality leading to Warburg effects. Damage to mitochondria were also noted by common pesticides tested in China and cancer associations were also found for many pesticides supporting a similar contributory etiology. Heart health concerns were raised by these findings because of the myriad mitochondria in the heart and because of long term reliability needs. Studies suggesting hearts were affected by Abs and pesticide exposure were presented. Because of their geographical ubiquitousness and the huge range of diseases associated with mitochondrial dysfunction, antibiotics and pesticides and bacteriocidal biocides are of concern for biodiversity and life in general. I propose research steps to evaluate Abs safety and suggest directions for further research and make suggestions on ways to ameliorate Abs toxicity.
Evidence of woven bone formation in carotid artery plaques
Published on: 5th January, 2021
OCLC Number/Unique Identifier: 8877223434
Objective: Plaque morphology plays an important prognostic role in the occurrence of cerebrovascular events. Echolucent and heterogeneous plaques, in particular, carry an increased risk of subsequent stroke. Depending on the quality of the plaque echogenicity based on B-mode ultrasound examination, carotid plaques divide into a soft lipid-rich plaque and a hard plaque with calcification. The aim of this study was to investigate structural changes in the basement membrane of different carotid artery plaque types.
Patients and methods: Biopsies were taken from 10 male patients (average age; 75 + 1 years) and 7 females (68 + 3 years). The study population included patients suffering from a filiform stenosis of the carotid artery, 8 patients with acute cerebrovascular events and 9 with asymptomatic stenosis. Scanning electron and polarised light microscopic investigations were carried out on explanted plaques to determine the morphology of calcified areas in vascular lesions.
Results: By means of scanning electron microscopy, multiple foci of local calcification were identified. The endothelial layer was partially desquamated from the basement membrane and showed island-like formations. Polarised light microscopy allows us to distinguish between soft plaques with transparent structure and hard plaques with woven bone formation.
Conclusion: The major finding of our study is the presence of woven bone tissue in hard plaques of carotid arteries, which may result from pathological strains or mechanical overloading of the collagen fibers. These data suggest a certain parallel with sclerosis of human aortic valves due to their similar morphological characteristics.
An unusual presentation of atrioventricular nodal reentrant tachycardia
Published on: 12th February, 2021
OCLC Number/Unique Identifier: 8958459896
Introduction: Atrioventricular nodal reentrant tachycardia (AVNRT) is the most frequent supraventricular tachycardia, commonly manifesting as autolimited paroxysmal episodes of rapid regular palpitations that exceed 150 beats per minute (bpm), dizziness and pounding neck sensation.
Case presentation: We present a case of a male patient, 70 years old, with ischemic heart disease and slow-fast AVNRT treated with radiofrequency catheter ablation (RFCA) in March 2019, with regular 6-months follow-ups. He was readmitted in our department in November 2020 for rest dyspnea and incessant fluttering sensation in the neck, without palpitations. The event electrocardiogram (ECG) was initially interpreted by general cardiologist as accelerated junctional rhythm, 75 bpm. Due to the persistence of symptoms and ECG findings, a differential diagnosis between reentry and focal automaticity was imposed. The response to vagal maneuvers and Holter ECG monitoring characteristics provided valuable information. We suspected recurrent slow ventricular rate typical AVNRT, which was confirmed by electrophysiological study and we successfully performed the RFCA of the slow intranodal pathway.
Conclusion: AV nodal reentry tachycardia may have an unusual presentation, occurring in elder male patients with structural heart disease. Antiarrhythmic drugs can promote reentry in this kind of patients. In cases of slow ventricular rate, vagal maneuvers and Holter ECG monitoring can help with the differential diagnosis. The arrhythmia can be successfully treated with RFCA with special caution regarding the risk of AV block.
Abdominal obesity in predicting myocardial infarction risk. Waist-to-Hip Ratio: The metric that confused cardiology worldwide for a long time
Published on: 24th March, 2021
OCLC Number/Unique Identifier: 8980361078
Important differences has been found in assessing the effects of obesity on cardiovascular disease (CVD) risk [1]. Interestingly, accurate estimation of the body composition (BC) is highly relevant from a public health perspective [2], and it has the importance of being essential in establishing the impact of adiposity on increased myocardial infarction (MI) risk. However, in non-randomized studies, baseline differences of BC between groups to be compared may introduce bias in results.
pVAD-assisted left main DK-Crush Bifurcation PCI Post-ViV TAVR
Published on: 16th April, 2021
OCLC Number/Unique Identifier: 9026739529
We describe successful percutaneous coronary intervention (PCI) of significantly diseased ostial left main (LM) and distal LM bifurcation (Medina 1,1,1) in a patient with a reduced left ventricular ejection fraction and a recent valve-in-valve balloon-expandable TAVR using the DK-Crush technique with the support of a percutaneous left ventricular assist device.
A Short Synthesis Concerning Biological Effects and Equivalent Doses in Radiotherapy
Published on: 15th April, 2017
The limits of classical equivalent computation based on time, dose, and fractionation (TDF) and linear quadratic models have been known for a long time. Medical physicists and physicians are required to provide fast and reliable interpretations regarding the delivered doses or any future prescriptions relating to treatment changes. In this letter, we propose an outline related to the different models usable for equivalent and biological doses that are likely to be the most appropriate. The used methodology is based on: the linear-quadratic-linear model of Astrahan, the repopulation effects of Dale, and the prediction of multi-fractionated treatments of Thames.
Assessment of the effect of cigarette smoking on the different denture base material
Published on: 13th August, 2019
OCLC Number/Unique Identifier: 8235041431
Background: The present study was conducted to assess effect of cigarette smoking on different denture base material.
Materials & Methods: The present study was conducted in the department of Prosthodontics. A total of sixty wax specimens in the shape of circular discs were prepared. These were divided into two groups. Group I (30) specimens were heat‑cured denture base materials and group II (30) specimens were flexible denture base materials. Both specimens were further divided into four subgroups of 15 each. Subgroup I was heat‑cured denture base material specimens (control group), subgroup II was flexible denture base material specimens (control group), subgroup III was heat‑cured denture base material specimens exposed to cigarette smoking (study group) and subgroup IV was flexible denture base material specimens exposed to cigarette smoking (study group). The initial (IRa) and final (FRa) surface roughness was measured before and after smoking test of the specimens.
Results: It was observed that in group I, mean IR (µm) value was 0.182 and FR value was 0.572. In group II, mean IR (µm) value was 0.265 and FR value was 0.831. In group III, mean IR (µm) value was 0.195 and FR value was 1.892. In group IV, mean IR (µm) value was 0.291 and FR value was 1.892. The difference was significant (P< 0.05).
Conclusion: The surface roughness of the specimens fabricated from the flexible denture base material was found to be more compared to heat‑cured denture base specimens after exposure to cigarette smoke. There is need to educate the patients regarding cleanliness of denture to avoid infection in the oral cavity.
The outcome of Acute Kidney Injury in patients with severe Malaria
Published on: 8th November, 2017
OCLC Number/Unique Identifier: 7317600169
Background: Acute kidney injury (AKI) is a frequent and serious clinical complication in patients with severe malaria. The purpose of this study was to assess the incidence of AKI in a large population of hospitalized patients with a primary admission diagnosis of malaria, and to investigate the robustness of the KDIGO criteria for predicting the need for dialysis, length of hospital stay and hospital mortality.
Results: We studied 695 consecutive patients admitted with primary diagnoses of malaria, in a 6 months period. AKI occurred in 86 (12.4%) patients (Stage 1 in 30.2%, Stage 2 in 23.3% and Stage 3 in 46.5%), and 19 (22.1%) patients required hemodialysis. No patient in the no-AKI or AKI Stage 1 groups (admission or maximum AKI Stage) required hemodialysis, and the requirement of hemodialysis was higher in patients with AKI Stage 2 (23.1%) and Stage 3 (42.4%). The length of hospital stay was longer (7.3±7.4 days vs 5.1±3.0 days; t=4.996, p<0.0001), and mortality was higher in patients who developed AKI than in those who did not (22,5% vs 2,5%; χ2=79.52; p<0.0001). Patients with AKI Stage 1, 2 and 3 had significantly higher hospital mortality (11%, 23% and 30%, respectively), compared with 2.5% for patients without AKI [odds ratio 5.2 (1.40-19.11, p=0.0331), 13.2 (4.24-41.06, p=0.0002), and 16.9 (7.26-36.65, p<0.0001)], respectively.
Conclusion: In a relatively large cohort of patients with falciparum malaria infection, the KDIGO criteria identified 12.4% with a diagnosis of AKI. The KDIGO classification was robust in this population for predicting the need for dialysis, length of hospital stay and hospital mortality. The results support the utilization of the KDIGO criteria in diagnosis and to predicting outcomes for patients with malarial AKI.

I submitted an editorial titled, 'Edible vaccines to combat Infectious Bursal Disease of poultry' for publication in ABB. After submitting the manuscript; the services rendered by the management and technical personnel to handle and process the manuscript were marvelous. Plagiarism report was shared with me with complements before reviewers' comments, All steps including article processing and service charges were well taken care of keeping in view the author's interest/preference. All together, it was an encouraging and wonderful experience working with ABB personnel.
