ABSTRACT
AIM: The present study compared the safety, efficacy, and tolerability of the new fixed-dose combination (FDC) of telmisartan 40 mg + bisoprolol 5 mg (TBP) tablets with the existing comparator FDC telmisartan 40 mg + metoprolol succinate ER 50 mg (TMS) tablets in patients with stage 1 and stage 2 hypertension. METHODOLOGY: The multicentric, double-blind, parallel-group, comparative, prospective, phase-III clinical study involved 264 subjects with stage 1 and stage 2 hypertension from 10 centres across India. The selected subjects were randomized into two groups: group A received the TMS and group B received the new FDC TBP. The primary endpoint was the mean change in seated systolic blood pressure (SeSBP) and seated diastolic blood pressure (SeDBP) from baseline to week 12 in both the control and study arms. The secondary endpoint was achieving the target of SeSBP <140 mmHg and SeDBP <90 mmHg from baseline to week 12 in both groups. Safety and tolerability parameters were evaluated in both groups based on adverse effects (AEs) reported by the patients and the physician. RESULTS: Both treatment groups exhibited a reduction in BP after 2 weeks of treatment, which was sustained until 12 weeks. The mean change in SeSBP and SeDBP at weeks 2, 6, and 12 compared to the previous visit showed statistical significance (p < 0.001) in all cases for both groups A and B. The mean changes in SeSBP and SeDBP from baseline to study end were numerically higher in group B than in group A. The mean difference in SeSBP from baseline to study end was significantly higher in group B compared to group A (p = 0.029). By week 12, 88.28 % and 89.84 % of subjects in group B achieved SeSBP <140 mmHg and SeDBP <90 mmHg respectively, while 86.71 % and 91.40 % of subjects in group A achieved the same targets. Reported AEs were mostly mild to moderate in both treatment groups, and no serious AEs or deaths were reported. Tolerability was rated as 'excellent' by 93.75 % of subjects in group B and 91.40 % of subjects in group A. CONCLUSION: Both the new FDC TBP and the existing comparator TMS combination therapy have comparable efficacy, tolerability, and safety for the management of stage 1 and stage 2 hypertension.

Background: Despite significant advances in neonatal care, neonatal sepsis remains a major contributor to mortality, morbidity, and protracted hospitalization. The development of early possible diagnostic indicators for newborn sepsis is critical. Since calprotectin participates in major biological processes, it could be a diagnostic marker for infection/inflammation. This study aimed to estimate serum calprotectin in neonates with clinical sepsis. In addition, we compared serum calprotectin with standard sepsis markers and serum procalcitonin to evaluate its diagnostic accuracy. Methods: A hospital-based cross-sectional diagnostic study of neonates identified with clinical sepsis using standard criteria was carried out. We compared estimated serum calprotectin levels to serum procalcitonin levels and conventional sepsis markers (leucocyte count, blood culture, immature to total neutrophil ratio, and C- reactive protein). We used SPSS version 25 to analyze the data. To examine diagnostic accuracy and determine a cut-off value for serum calprotectin, we used the receiver operating characteristics (ROC) curve. Results: Of the 83 subjects included, 36.5% (30/83) had blood culture positive status, the median value of serum calprotectin being 0.93 ng/ml (0.67 to 1.3). Respiratory, cardiovascular, and gastrointestinal instabilities were present in 67.5% (56/83), 59% (49/83), and 50.1% (42/83) cases, respectively. The median values of serum calprotectin, procalcitonin, TLC, and I/T ratio between neonates withpositive blood culturesand negative culturesdid not differ significantly.. On ROC, calprotectin was not predictive for blood culture positivity (sensitivity: 50%; specificity: 44% at 0.83 ng/ml of serum calprotectin) and C-reactive protein (CRP) levels (sensitivity: 57%; specificity: 67% at serum calprotectin levels of 0.89 ng/ml). However, compared with serum procalcitonin, serum calprotectin at 1.2 ng/ml had sensitivity and specificity of 60% and 73%, respectively. Conclusions: Serum calprotectin did not show a distinct advantage over the existing sepsis markers. Serum calprotectin level at 1.2 ng/ml had a sensitivity and specificity of 60% and 73%, respectively, compared to serum procalcitonin in detecting neonatal sepsis.

Background: The adoption of remote classes for students has been in vogue since the onset of the pandemic. Schools reopened in a phased manner after the second wave of coronavirus disease 2019 (COVID-19) in India. Reverting to the regular face-to-face teaching for students became a challenge to the teachers and students, especially at times when there was an impending third wave on the way. The study aimed to assess the presence of symptoms of depression, anxiety, and stress in teachers who attended reopened schools in the scenario of face-to-face classes. In addition, we studied the association of psychological symptoms with teachers' age groups, gender, school boards, and school institution type. Methods: A cross-sectional study was conducted between October to December 2021 after schools had reopened. Data was collected using Google Form questionnaires in 124 schoolteachers. The Depression, Anxiety, and Stress Scale - 21 Items (DASS-21) questionnaire assessed the psychological symptoms. Results: Of 124 schoolteachers, 108(87.1%) were female, 112 (90.3%) were from private institutions, and 70(56.5%) were from Central Board of Secondary Education (CBSE) school boards. The prevalence of depression, anxiety, and stress in teachers was 30.6%, 45.2%, and 20.2%, respectively. Nearly 80% of the female teachers expressed depression, anxiety, and stress symptoms. Amongst all the age groups, symptoms were higher in 40-49 group. We found anxiety to be statistically significant when compared with gender (p-0.042). We found no statistically significant differences concerning age groups, school boards, or school institutions with any psychological symptoms. Conclusions: The prevalence of psychological symptoms was high among schoolteachers after schools reopened for regular face-to-face teaching. Gender was associated with anxiety in teachers. We agree that identifying teachers' symptoms and providing adequate psychological counseling/support would improve their mental health status and thereby the quality of teaching to students.

COVID appropriate behavioral measures need to be followed once school reopens. School teachers being in the forefront could substantiate the feasibility of suggested safety measures. This study aimed to assess teachers' perceptions towards COVID appropriate behaviors for children with school reopening and compare their mean scores between public versus private schools and across school boards. We conducted an observational school-based study of teachers over two months. Perceptions were scored using a five-point Likert symmetric agree to disagree scale. Results were expressed as proportions and analyzed using an independent sample t-test. Of the 547 teachers surveyed, most (> 90%) agreed to the suggested social distancing and hygiene measures. There was a significant difference in perception scores between private versus public schools and across boards regarding i) reducing the academic syllabus, ii) adopting a cloud-based system to integrate online-offline learning, and iii) conducting meetings online. In addition, measures such as i) teaching classes on alternate days with a limited number of children, ii) arranging benches/desks to maintain six feet distance between students, iii) dealing with psychological stress by counselors, and iv) arrangement with local hospitals for medical services were significant statistically across school boards. To conclude, most schoolteachers agreed with the need for social distancing and hygiene measures for children. There was a significant difference in perceptions between public versus private schools and across boards regarding academic syllabus, integration of online-offline student learning, number of children per class, the timing of classes, student seating arrangement, and medical/psychological guidance availability.
ABSTRACT
Introducción: La velocidad de la onda de pulso y la rigidez arterial se considera estándar de oro para evaluar daño a órganos diana que haya surgido subclinicamente. La disfunción endotelial es directamente proporcional al desarrollo de la aterosclerosis preclínica. Estos marcadores sustitutos mencionados anteriormente son relativamente más altos en pacientes con hipertensión no controlada o resistente. El objetivo fue evaluar si la rigidez arterial y la velocidad de la onda del pulso también son marcadores sustitutos del desarrollo de la aterosclerosis preclínica en pacientes con hipertensión resistente. Métodos y materiales: Se incluyeron en el estudio un total de 160 pacientes con hipertensión resistente de Croacia e India. La presión arterial central y otros valores clínicos se evaluaron utilizando un dispositivo no invasivo. Resultados: Las estadísticas del grupo se hicieron con perspectiva de género, los valores de la presión arterial sistólica (PA-S), la presión arterial diastólica (PA-D), la presión arterial media (PAM), la presión central sistólica (PC-S) ,la presión central diastólica ( PC-D), la presión de pulso central (cPP) y la velocidad de la onda de pulso (VOP) han sido descritas. Los valores de PA-S en hombres / mujeres fueron 147.26 ±22.12/ 144.10 ± 21.29; los valores de PA-D en hombres/mujeres fueron 94.98 ± 13.36 / 88.57 ± 12.25 respectivamente. Conclusiones: con los resultados obtenidos se puede concluir que la rigidez arterial es un marcador independiente que es directamente proporcional a la disfunción endotelial y al desarrollo de aterosclerosis preclínica.
Introduction: Pulse wave velocity and arterial stiffness are considered a gold standard for evaluating target organ damage that has arisen subclinically. Endothelial dysfunction is directly proportional to the development of preclinical atherosclerosis. These surrogate markers mentioned above are relatively higher in patients with uncontrolled or resistant hypertension. The objective was to assess whether arterial stiffness and pulse wave velocity are also surrogate markers for the development of preclinical atherosclerosis in patients with resistant hypertension. Methods and materials: A total of 160 patients with resistant hypertension from Croatia and India were included in the study. Central blood pressure and other clinical values were evaluated using a non-invasive device. Results: The statistics of the group were made with gender perspective, the values of the systolic blood pressure (PA-S), the diastolic blood pressure (PA-D), the mean arterial pressure (MAP), the central systolic pressure (PC-S), central diastolic pressure (PC-D), central pulse pressure (cPP) and pulse wave velocity (VOP) have been described.The PA-S values in men / women were 147.26 ± 22.12 / 144.10 ± 21.29; PA-D values in men / women were 94.98 ± 13.36/88.57 ± 12.25 respectively. Conclusions: with the results obtained, it can be concluded that arterial stiffness is an independent marker that is directly proportional to endothelial dysfunction and the development of preclinical atherosclerosis.

BACKGROUND: Andersen-Tawil syndrome (ATS) is a rare familial periodic paralysis that typically also affects the heart and skeletal system. Ventricular arrhythmias (VAs) are profound and difficult to control, but minimally symptomatic. In this report, we describe an atypical phenotype of ATS in two related families. We also report our experience with phenytoin sodium for the control of resistant VAs in these patients. METHODS AND RESULTS: Between 2014 and 2018, seven siblings were diagnosed with ATS on the basis of cardiac arrhythmias and genetic evaluation. Heterozygous mutation with c.431G > C (p.G144A) in exon 2 of KCNJ2 gene was observed in all patients. Characteristic cardiac manifestations were noted in all patients but periodic paralysis or objective neurological involvement was distinctly absent. Phenytoin was considered for control of symptomatic VA in three patients. Intake of oral phenytoin (5 mg/kg/day) for 1 month completely suppressed VA (<1% in 24-h Holter monitoring) in two patients, and significantly in the third (8% per 24 h) patient. Phenytoin was well-tolerated in all three patients. CONCLUSIONS: We describe a cardiac-predominant phenotype in ATS. ATS should be suspected in patients with typical cardiac manifestations even in the absence of periodic paralysis. Our initial experience with short-term use of phenytoin for control of resistant VAs is encouraging.

Nanjegowda CK, Kamath SP, Kamath P, Shah TD, Kulkarni V, Lashkari HP, Baliga BS. Comparison of diastolic function in children with transfusion dependent beta thalassemia major by tissue and conventional doppler imaging indices and its correlation with serum ferritin levels. Turk J Pediatr 2019; 61: 250-259. Regular blood transfusions for children with beta thalassemia major (ß- TM) results in iron overload cardiomyopathy/cardiac failure. Mortality in these children is most often because of heart failure. We compared Tissue Doppler Imaging (TDI) and conventional pulse wave Doppler (PWD) indices in evaluating diastolic function in chronically transfused ß-TM children and correlated the Doppler indices with mean serum ferritin levels. This was a prospective cross-sectional study conducted at tertiary teaching hospital. ß-TM children aged 3 to 18 years were enrolled as per inclusion criteria. PWD parameters at the mitral inflow (E, A, E/A and DT) and TDI parameters at the medial mitral annulus (E'and E/E') were used for estimation of diastolic dysfunction. Of the 66 children with thalassemia, the mean age was 10.2±3.77yrs and 60.6% were boys. The E/E' ratio estimated diastolic dysfunction (34/66, 51.5%) greater than four times that assessed by E/A ratio indices (8/66, 12.1%) in the subjects. Association of serum ferritin levels with E/E' ratio by chi square test was significant statistically (P=0.027), however was not significant with E/A ratio. By Mann Whitney test, the median serum ferritin levels (ng/ml) were higher [4034.50, (IQR-2084-5340.25) in those with diastolic dysfunction (abnormal E/E'), when compared to those with normal E/E'[2037.50(1510.75- 3572.25)], with their difference being significant (p=0.011), however serum ferritin levels were not significant with E/A ratio and DT. E/E' parameter had a sensitivity and specificity of 76.5% and 53.1% respectively at a mean serum ferritin cutoff level of 2076 ng/mL by ROC analysis. In conclusion, TDI is a more reliable modality for diagnosing early diastolic dysfunction when compared to PWD. Threshold level of serum ferritin greater than 2076 ng/mL is associated with increased incidence of diastolic dysfunction.

BACKGROUND: Purkinje fiber-mediated arrhythmias in the setting of acute myocardial infarction are poorly responsive to conventional antiarrhythmic therapy, increases overall mortality and often requires radiofrequency ablation (RFA) for control. In this study, we report the use of intravenous Fosphenytoin for the control of arrhythmic storm in patients with acute myocardial infarction. METHODS AND RESULTS: Six patients with acute myocardial infarction (5 AW/1 LW) and Purkinje-triggered ventricular arrhythmias refractory to conventional antiarrhythmics were treated with intravenous Fosphenytoin before considering RFA. Arrhythmia control was obtained in all patients after the initial bolus dose. Breakthrough episodes were seen in 5/6 within 24-36 hours of the initial bolus, necessitating a second bolus. Complete arrhythmia control was obtained in all patients within 72 hours and 5/6 patients were successfully discharged from the hospital. One patient succumbed to sepsis in hospital while another patient succumbed to Sub Dural Hematoma after 3 months. CONCLUSIONS: Intravenous Fosphenytoin should be considered before RFA for control of Purkinje fiber-mediated refractory arrhythmias in acute myocardial infarction patients.

BACKGROUND: Cardiac Resynchronization therapy (CRT) remains largely under-used in developing countries owing to the high cost of therapy. In this pilot study, we explore 'optimized' Left Ventricle Only Pacing (LVOP) as a cost effective alternative to cardiac resynchronization therapy in selected patients with heart failure. HYPOTHESIS: In economically poorer patients with heart failure, left bundle branch block (LBBB) and intact AV node conduction, synchronization can be obtained using a dual chamber pacemaker (leads in right atrium and Left ventricle) with the help of 2D strain imaging. METHODS AND RESULTS: 4 patients underwent LVOP for symptomatic heart failure. Post procedure 'optimization' was done using 12 lead electrocardiography and 2D- Strain imaging. Difference between Time to Peak longitudinal strain and Aortic valve Closure (Diff TPL-AC) was calculated for each segment at different AV delays and the AV delay with the smallest Diff TPL-AC was programmed. The mean AV delay that resulted in electrical and mechanical synchrony was 150 ms. After a mean follow up of 6 months, all patients had improved by at least 1 NYHA class. The mean reduction in QRS duration post procedure was -54.5 ± 22.82 ms and the mean improvement in EF was 7 ± 2.75%. CONCLUSION: Optimized LVOP using 2D strain and ECG can be a cost-effective alternative to CRT in patients with LBBB, heart failure and normal AV node conduction.
ABSTRACT
BACKGROUND AND OBJECTIVES: We analyzed Lead II in patients undergoing an Oral Flecainide Challenge test (FCT), to identify any pointers that could predict a positive FCT and thereby help in recognition of latent BS. METHODS: The following parameters in lead II were retrospectively analyzed from the pre-test ECG in 62 patients undergoing FCT for suspected BS: The presence or absence of S waves, S wave amplitude, duration and upslope duration; J point parameters- Early repolarization, QRS notch, and QRS Slur; ST segment parameters-lack of isoelectric ST segment, ST duration and QT interval. RESULTS: 48 had positive FCT (Group-1) while 14 were negative for FCT(Group-2). Lack of an isoelectric ST segment (50% vs 14.29%, p = 0.018) and slurring of QRS (33.33% vs 0%, p = 0.014) was more common in Group-1 than Group-2. Group-1 had shorter ST segment duration (median 81.5 (IQR 64-103.5) vs 110 (IQR 90-132), p = 0.002) and shorter ST: QT ratio (median 0.28 (IQR 0.22-0.35) vs 0.23 (0.18-0.27), p = 0.007). QRS notch/depressed J point (87.5%), QRS slur (100%), and lack of isoelectric ST segment (92.31%) had high sensitivity for predicting an inducible Type 1 Brugada pattern. Combining two parameters- ST: QT ratio<0.24 and lack of isoelectric ST segment-considerably improved the specificity (73.3%), and the positive predictive value of the test to 76%. The results remained accurate when validated in a small prospective cohort. CONCLUSION: Shortened ST segment in Lead II, lack of isoelectric ST segment, slurred QRS and ST/QT ratio <0.24 are predictive of underlying Brugada pattern in baseline ECG.
ABSTRACT
BACKGROUND: There is a substantial reduction in cardiovascular related morbidity and mortality in the general population attributed to improved treatment of cardiac risk factors and disease, the same magnitude of benefit has not been observed in those with diabetes mellitus. The aim of the present study was to evaluate factors associated with the cardiac outcome at 1 year after coronary angiogram in patients with type 2 diabetes mellitus and to compare the outcomes with nondiabetics. METHODS: A retrospective cohort study was carried out in subjects who underwent coronary angiogram for an evaluation of CAD, with follow-up data available for period of 12 months. The data consisted of 208 type 2 diabetic and 75 non-diabetic patients. Clinical, anthropometric and other biochemical risk factors of the study participants were recorded. Univariate and multivariate cox proportional hazard regression analyses were performed to evaluate the relation between the cardiovascular risk factors and major adverse cardiac events (MACE). RESULTS: At 1 year, MACE was observed in 50 (24.04%) type 2 diabetic subjects, which included non-fatal myocardial infarction 24 (11.54%), target vessel revascularization 15 (7.21%) and death 11 (5.29%). The area under the curve for insulin in predicting MACE was found to be 0.81 (95% CI 0.73-0.88) with sensitivity and specificity of 88% (95% CI 0.71-0.96) and 74% (95% CI 0.65-0.81) respectively. After adjustment for potential confounders hyperinsulinemia (>20 µIU/ml) was significantly associated with MACE [adjusted hazard ratio (HR): 3.03, 95% CI 1.41-6.54, p = 0.005]. Interestingly, the MACE rate in type 2 diabetics with insulin levels <20 µIU/ml (10.2%) and non-diabetics (12%) (p = 0.676) appears to be same. CONCLUSIONS: In addition to severity of the CAD at the baseline, basal hyperinsulinemia beyond a threshold strongly predicts adverse cardiac events at 1 year in type 2 diabetes mellitus. Those below the threshold, appears to be having a risk equivalent to non-diabetics.
ABSTRACT
AIMS: To develop a risk score, for identifying severe and complex CAD in patients with type 2 diabetes mellitus. METHODS: In this cross sectional study, 179 patients with type 2 diabetes mellitus undergoing coronary angiogram for the evaluation of suspected coronary artery disease (CAD) were recruited at a tertiary-care hospital. Patients were divided into developmental (n=124) and validation (n=55) cohorts. Biochemical and anthropometric parameters were analysed. Predictors of severe and complex CAD (SYNTAX Score>22) were identified by multiple logistic regression analysis. RESULTS: Insulin resistance>3.4 (OR: 21.26, 95% CI: 5.71-79.09), duration of diabetes>5years (OR: 13.50, 95% CI: 3.13-58.25), total cholesterol/HDL-C ratio>5 (OR: 2.75, 95% CI: 0.66-11.55) and waist circumference>96cm (OR: 5.08, 95% CI: 1.27-20.42) were independent predictors of severe and complex CAD, and Manipal Diabetes Coronary Artery Severity Score was developed. CONCLUSIONS: The prediction of severe and complex CAD was achieved with this simple score, and thus enabling effective identification of patients beforehand, who are not likely to be suitable for angioplasty.

AIM: The aim of our study was to compare the angiographic changes in 53 nondiabetic patients, 54 type 2 diabetic patients of less than 5 years of duration, 41 patients with 5-10 years of diabetes, and 27 with more than 10 years of diabetic duration. METHODS: In this cross-sectional study, 175 patients, who underwent coronary angiogram for the evaluation of the coronary artery disease (CAD), were recruited. Based on the angiographic findings, syntax score, vessel score, and coronary collaterals grading were analyzed. The biochemical analysis was done by using the auto analyzer. RESULTS: A significant increase in the mean syntax score (p=0.019), vessel score (p=0.007), and coronary collateral grade (p=0.008) was observed in the patients with 5-10 years of diabetes when compared to those with less than 5 years of diabetic duration. There was no significant difference in the mean syntax score (p=0.979), vessel score (p=0.299), and collateral grade (p=0.842) between the patients with 5-10 years and more than 10 years of diabetes. The difference in the mean syntax score (p=0.791), vessel score (p=0.098), and collateral grade (p=0.661) between the nondiabetic and the patients with less than 5 years of diabetes was not significant. CONCLUSION: A significant structural change in the coronary arteries was found among the patients with 5-10 years of diabetes.

BACKGROUND: Type 2 diabetes mellitus is an important risk factor in the development of coronary artery disease (CAD) and is often associated with severe disease. However, this risk is not uniform, some patients remain free of CAD even after many years of treatment for diabetes. The present study was aimed to identify the factors that are associated with a favorable CAD profile. METHODS: A case-control study of 76 patients with type 2 diabetes mellitus who were on treatment for more than 10 years duration and undergoing a coronary angiogram for the evaluation of clinically suspected CAD at a tertiary care hospital were recruited for the study. The presence and absence of significant CAD was determined after a coronary angiogram. Clinical history, and anthropometric and biochemical parameters were analyzed. Insulin resistance was determined by the Homeostasis Model Assessment. Multiple logistic regressions were done to find out the factors associated for a favorable CAD profile. RESULTS: The difference in HOMA-IR (2.37 ± 0.69 VS 3.77 ± 1.64, p < 0.001) and urine microalbumin (24.15 ± 32.16 VS 82.72 ± 117.70, p = 0.004) were found to be statistically significant among those who did not have CAD when compared to those who had CAD. The difference in lipid profile, HbA1C, fasting blood sugar, BMI, waist hip ratio, waist and hip circumference was not significant. The adjusted odds ratio for insulin resistance less than 2.5 (OR 9.09, 95 % CI 1.91-41.83, p = 0.005), females (OR 7.91, 95% CI 1.55-40.38, p = 0.013) and microalbumin <20 mg/l (OR 4.57, 95% CI 1.17-17.85, p = 0.029) were independently associated with normal coronaries. The adjusted odds ratio for lipid profile, BMI, blood pressure and HbA1C were not significant. CONCLUSIONS: HOMA-IR less than 2.5, microalbuminuria less than 20 mg/l and females are the factors appear to be associated with no apparent CAD.

BACKGROUND: Insulin resistance (IR) has known to be associated with coronary artery disease (CAD), but the assessment of severity of the CAD based on IR in type 2 diabetes mellitus has not been established in detail. AIMS: The aim of our study was to establish the correlation between IR and the severity of CAD in type 2 diabetes mellitus. MATERIALS AND METHODS: In a cross-sectional study design, 61 consecutive patients with type 2 diabetes mellitus who underwent coronary angiogram for the evaluation of CAD were recruited. Fasting blood glucose, fasting insulin levels, systolic blood pressure and total cholesterol/high density lipoprotein-cholesterol ratio were determined. Homeostasis model assessment-IR (HOMA-IR) was correlated with severity of CAD, which was measured by modified Gensini Score. RESULTS: There was a significant correlation between log HOMA-IR and severity of CAD (r = 0.303, P = 0.009) in diabetic patients. Correlation of the Gensini Score with other known risk factors was not significant. CONCLUSIONS: The results of our study indicate that we might able to predict the severity of CAD by measure of IR.
