Position statement from the Indian Society of Gastroenterology, Cardiological Society of India, Indian Academy of Neurology and Vascular Society of India on gastrointestinal bleeding and endoscopic procedures in patients on antiplatelet and/or anticoagulant therapy. Indian J Gastroenterol 2023; 42:332-346.

Abstract
Antiplatelet and/or anticoagulant agents (collectively known as antithrombotic agents) are used to reduce the risk of thromboembolic events in patients with conditions such as atrial fibrillation, acute coronary syndrome, recurrent stroke prevention, deep vein thrombosis, hypercoagulable states and endoprostheses. Antithrombotic-associated gastrointestinal (GI) bleeding is an increasing burden due to the growing population of advanced age with multiple comorbidities and the expanding indications for the use of antiplatelet agents and anticoagulants. GI bleeding in antithrombotic users is associated with an increase in short-term and long-term mortality. In addition, in recent decades, there has been an exponential increase in the use of diagnostic and therapeutic GI endoscopic procedures. Since endoscopic procedures hold an inherent risk of bleeding that depends on the type of endoscopy and patients' comorbidities, in patients already on antithrombotic therapies, the risk of procedure-related bleeding is further increased. Interrupting or modifying doses of these agents prior to any invasive procedures put these patients at increased risk of thromboembolic events. Although many international GI societies have published guidelines for the management of antithrombotic agents during an event of GI bleeding and during urgent and elective endoscopic procedures, no Indian guidelines exist that cater to Indian gastroenterologists and their patients. In this regard, the Indian Society of Gastroenterology (ISG), in association with the Cardiological Society of India (CSI), Indian Academy of Neurology (IAN) and Vascular Society of India (VSI), have developed a "Guidance Document" for the management of antithrombotic agents during an event of GI bleeding and during urgent and elective endoscopic procedures.

Abstract
A parturient with VACTERL association (vertebral defects, anal atresia, cardiac defects, trachea-oesophageal fistula, renal abnormalities and limb abnormalities) was listed for an elective caesarean section. She had a short neck with reduced cervical extension and flexion. Magnetic resonance imaging of her whole spine was performed which showed failure of cervical spine segmentation and cervical stenosis. Neuraxial blockade could have resulted in unpredictable spread of local anaesthetic due to the low volume of the spinal canal, and could have caused myelopathic changes within the spinal cord due to cerebrospinal fluid pressure changes. A general anaesthetic using a rapid sequence induction was also predicted to be challenging due to her fixed, unstable neck and severe cervical spine stenosis. After a multidisciplinary discussion Including neurosurgeons, we planned for awake tracheal intubation followed by general anaesthesia. However, before the date of her planned delivery, she required an urgent caesarean section due to severe preeclampsia. This was performed under general anaesthesia following uncomplicated awake tracheal intubation.

Clinical relevance of double-arm blood pressure measurement and prevalence of clinically important inter-arm blood pressure differences in Indian Primary Care. J Clin Hypertens (Greenwich) 2022. [PMID: 36468352 DOI: 10.1111/jch.14456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 02/13/2022] [Accepted: 02/17/2022] [Indexed: 12/12/2022]
Abstract
Hypertension guidelines recommend measuring blood pressure (BP) in both arms at least once. However, this is seldom done due to uncertainties regarding measurement procedure and the implications of finding a clinically important inter-arm BP difference (IAD). This study aimed to provide insight into the prevalence of clinically important IADs in a large Indian primary care cohort. A number of 134678 (37% female) unselected Indian primary care participants, mean age 45.2 (SD 11.9) years, had BP measured in both arms using a standardized, triplicate, automated simultaneous measurement method (Microlife WatchBP Office Afib). On average, there were clinically minor differences in right and left arm BP values: systolic BP 134.4 vs. 134.2 mmHg (p<0.01) and diastolic BP 82.7 vs. 82.6 mmHg (p<0.01), respectively. Prevalence of significant mean systolic IAD between 10 and 15 mmHg was 7813 (5.8%). Systolic IAD ≥ 15 mmHg 2980 (2.2%) and diastolic IAD ≥ 10 mmHg 7151 (5.3%). In total, there were 7595 (5.6%) and 8548 (6.3%) participants with BP above the 140/90 mmHg threshold in only the left or right arm, respectively. Prevalence of participants with elevated BP on one arm only was highest in patients with a systolic IAD ≥ 15 mmHg; 19.1% and 13.7%, for left and right arm, respectively. This study shows that a substantial prevalence of IAD exist in Indian primary care patients. BP is above the diagnostic threshold for hypertension in one arm only for 6% of participants. These findings emphasise the importance of undertaking bilateral BP measurement in routine clinical practice. This article is protected by copyright. All rights reserved.

Abstract
In the present study, principal component analysis (PCA) is used to investigate the processes controlling groundwater salinity in the Mewat (Nuh) district, Haryana, India. Twenty groundwater samples were collected from salinity-affected areas in the March-April months of years 2018 and 2019 and were analyzed for chemical variables pH, EC, Ca2+, Mg2+, Na+, K+, [Formula: see text], Cl-, SO42-, [Formula: see text], TDS, and total hardness. Three principal components were selected based on the eigen value, which explains 79.58% and 85.08% of the total variation in the years 2018 and 2019, respectively. The first principal component (PC-1) is identified with salinity, the second principal component (PC-2) with alkalinity, and the third principal component (PC-3) described the pollution. When the yearly comparison was made, the samples collected in 2019 were found to have an increased salinity compared to 2018, which shows an increased vulnerability to the aquifer of Mewat on account of the decline in rainfall recharge. It was also evident that declining recharge also triggered the recharge from other sources; thus, the impact of pollution is more pronounced in 2019 compared to 2018.

Abstract
OBJECTIVE The study aimed to evaluate the impact of the COVID-19 pandemic on levels of anxiety and depressive symptoms in children and adolescents. DESIGN Cross-sectional surveys were carried out on the mental health of children; one survey was conducted before the COVID-19 pandemic and one into the pandemic, 15 months after the school closures and implementation of lockdown and social distancing. Demographic data and COVID-19 pandemic-related data were collected from specific parent-report and self-report questionnaires. PARTICIPANTS Participants included children and adolescents between ages 6 and 16 years, attending a tertiary care hospital without any diagnosed major psychiatric or chronic disorder. ANALYSIS Data were collected at two points (before the COVID-19 pandemic and during it) and compared. Levels of anxiety and depressive symptoms were compared and tested for statistically significant differences between these two points using appropriate statistical tests. Regression models were constructed to predict the factors affecting increased anxiety levels and depressive symptoms in the COVID-19 period. RESULTS 832 and 1255 children/adolescents were included in the study during the pre-COVID-19 and COVID-19 times, respectively. The median age of the participants was 10 years (IQR=4 years). The median (IQR) Spence Children's Anxiety Scale score was 24 (12) at the pre-COVID-19 point and 31 (13) during the COVID-19 pandemic (p<0.001, r=-0.27). 11% and 16% of children reported being depressed at these two-time points, respectively (p=0.004, φc=-0.063). Regression analysis showed that many factors, including the duration of smartphone use, female gender and only child status, were associated with increased anxiety or depression levels. CONCLUSION A large proportion of children had elevated anxiety and depressive symptoms during the pandemic relative to before the pandemic, suggesting a need for measures to engage children in healthy habits to protect children's mental health and continuous monitoring of children during such scenarios.

Serial evaluation of vascular responses after implantation of everolimus-eluting coronary stent by optical coherence tomography. Catheter Cardiovasc Interv 2021; 99:381-390. [PMID: 34061443 DOI: 10.1002/ccd.29794] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 11/13/2020] [Accepted: 05/10/2021] [Indexed: 11/11/2022]
Abstract
AIM To evaluate healing response at strut-level and cross-section level after implanting an ultra-thin strut, everolimus-eluting stent with biodegradable polymer (Tetrilimus) using optical coherence tomography (OCT) at 3 and 6 months. METHODS This was prospective, multi-centre, single-arm, and investigator-initiated study performed at seven Indian sites between January, 2017 and September, 2018. OCT evaluations were performed in 57 patients who underwent Tetrilimus stent implantation. Follow-up OCT was scheduled at 3 months for first 16 patients and at 6 months for 41 patients. Primary outcomes included degree of strut coverage, malapposition and thickness of neointimal hyperplasia (NIH) over covered struts. RESULTS Sixty one Tetrilimus stents were implanted to treat 59 lesions in 57 patients. Paired (baseline and follow-up) OCT data was available for 12 patients and 30 patients at 3 and 6 months, respectively. At 3 months, rapid early healing was indicated by 95.48% covered struts per lesion with very low (0.11 ± 0.06 mm) NIH. At 6 months, NIH accumulation was greater (0.21 ± 0.07 mm) as compared to 3 months. 99.77% of struts per lesion were covered at 6 months. There was a very symmetrical healing as shown by very low eccentricity index. There was no difference in vascular healing between stents with small to moderate size vessels (≤3.00 mm) and large size vessels (>3.00 mm). CONCLUSION Present study demonstrated nearly complete endothelization and low NIH accumulation at 3 and 6 months following implantation of ultra-thin strut everolimus-eluting biodegradable polymer-coated Tetrilimus stent. Moreover, though being an ultra-thin strut stent, there was no difference in vascular healing and eccentricity after implantation of the Tetrilimus stents with smaller and larger diameters.

Abstract
Women are underrepresented in groups of patients seeking hypertension care in India. The present paper reports trends in office and ambulatory blood pressure measurement (OBPM, ABPM) and 24-h heart rate (HR) with sex in 14,977 subjects untreated for hypertension (aged 47.3 ± 13.9 years, males 69.4%) visiting primary care physicians. Results showed that, for systolic blood pressure (SBP), females had lower daytime ABPM (131 ± 16 vs. 133 ± 14 mm Hg, P < .001) but higher nighttime ABPM (122 ± 18 vs. 121 ± 16 mm Hg, P < .001) than males. Females had higher HR than men at daytime (80 ± 11 vs 79 ± 11.5 bpm) and nighttime (71 ± 11 vs 69 ± 11), respectively (all P < .001). Dipping percentages for SBP (7.4 ± 7.3 vs 9.3 ± 7.4%), DBP (10.1 ± 8.6 vs. 12.3 ± 8.9%), and HR (10.7 ± 7.9 vs. 12.8 ± 9.2%) were lower (P < .001) for females than for males, respectively. Females more often had isolated nighttime hypertension as compared to males (14.9%, n = 684% vs 10.6%, n = 1105; P < .001). BP patterns and HR showed clear differences in sex, particularly at nighttime. As females were more often affected by non-dipping and elevated nighttime SBP and HR than males, they should receive ABPM, at least, as frequently as men to document higher risk necessitating treatment.

Abstract
AIMS The aim of this study was to report whether the superiority of the everolimus-eluting stent (EES) vs. the paclitaxel-eluting stent (PES) at one-year follow-up in the Taxus Element versus Xience Prime in a Diabetic Population (TUXEDO)-India trial was sustained at longer-term follow-up. METHODS AND RESULTS One thousand eight hundred and thirty (1,830) patients with diabetes mellitus and coronary artery disease were randomised to EES vs. PES. Follow-up data up to two years were available in 1,701 (92.9%) patients. The primary endpoint was target vessel failure (TVF), defined as the composite of cardiac death, target vessel myocardial infarction (TV-MI), or ischaemia-driven target vessel revascularisation (TVR). Treatment with EES had a lower two-year rate of TVF (4.3% vs. 6.6%, p=0.03). Of the secondary endpoints, EES significantly reduced any MI (1.6% vs. 3.5%, p=0.01), TV-MI (0.7% vs. 3.1%, p=0.0001), ST (0.4% vs. 2.2%, p=0.001), cardiac death or target vessel MI (2.9% vs. 4.8%, p=0.04) and TLR (1.9% vs. 3.7%, p=0.02), compared with PES. Between one year and two years, no significant differences in the clinical outcomes were observed (pinteraction >0.05). CONCLUSIONS In this adequately powered trial, the benefits of EES vs. PES in a diabetic population seen at one year were maintained at two years.

Abstract
IMPORTANCE Prior studies have shown that patients with insulin-treated diabetes mellitus (ITDM) have a higher risk of cardiovascular events. However, this finding is controversial, as other studies have shown that the increased risk of cardiovascular events disappears after risk adjustment. In addition, the choice of a drug-eluting stent (limus- vs taxol-eluting) in ITDM is controversial, with studies showing worse outcomes with an everolimus-eluting stent compared with a paclitaxel-eluting stent. OBJECTIVES To assess the outcomes of patients with ITDM vs non-ITDM who underwent percutaneous coronary intervention and to assess the efficacy and safety of an everolimus-eluting stent vs a paclitaxel-eluting stent based on insulin use status. DESIGN, SETTING, AND PARTICIPANTS A prespecified analysis was conducted of the Taxus Element vs Xience Prime in a Diabetic Population (TUXEDO) clinical trial, which enrolled 1830 patients with ITDM and non-ITDM from June 23, 2011, to March 12, 2014. Patients were randomized 1:1 to receive either a paclitaxel-eluting stent or an everolimus-eluting stent. MAIN OUTCOMES AND MEASURES The primary end point was target vessel failure, defined as the composite of cardiac death, target vessel myocardial infarction, or ischemia-driven target vessel revascularization at 1 year after the intervention. RESULTS Among the 1830 patients (1377 male) in the TUXEDO trial, 747 patients (40.8%) were receiving insulin (ITDM group). Compared with the 1083 patients with non-ITDM, those with ITDM had a significant increase in target vessel failure (42 [5.6%] vs 36 [3.3%]; P = .02), death or myocardial infarction (43 [5.8%] vs 35 [3.2%]; P = .009), death (26 [3.5%] vs 18 [1.7%]; P = .01), and subacute stent thrombosis (8 [1.1%] vs 3 [0.3%]; P = .03). However, in a propensity score-adjusted analysis to account for baseline differences between the 2 groups, the differences in outcomes were no longer significant. In patients with ITDM, everolimus-eluting stents reduced the rate of target vessel failure (13 of 382 [3.4%] vs 29 of 365 [7.9%]; P = .007), major adverse cardiac events (15 of 382 [3.9%] vs 30 of 365 [8.2%]; P = .01), myocardial infarction (5 of 382 [1.3%] vs 16 of 365 [4.4%]; P = .01), stent thrombosis (2 of 382 [0.5%] vs 11 of 365 [3.0%]; P = .009), target lesion revascularization (4 of 382 [1.0%] vs 19 of 365 [5.2%]; P = .001), and target vessel revascularization (4 of 382 [1.0%] vs 19 of 365 [5.2%]; P = .001) when compared with paclitaxel-eluting stents. The results largely trended in the same direction in patients with non-ITDM (P > .05 for the interaction). CONCLUSIONS AND RELEVANCE Patients with ITDM had a significant increase in the risk of cardiovascular events in unadjusted models that was largely attenuated after propensity score adjustment. Everolimus-eluting stents reduced the rate of cardiovascular events, including stent thrombosis, when compared with paclitaxel-eluting stents in patients with ITDM.

Abstract
Kawasaki disease (KD) is an acute, self-limited vasculitis that occurs in young children and was first described by Japanese pediatrician Tomisaku Kawasaki in 1967. Although originally thought to be a rare condition, KD has become the most common cause of acquired heart disease in the pediatric population in developed countries. The majority of patients with KD appear to have a benign prognosis, but a subset of patients with coronary artery aneurysms are at risk for ischemic events and require lifelong treatment. In the 4 decades since the initial recognition of KD, the number of patients reaching adulthood has continued to grow. Adult cardiologists will be increasingly involved in the management of these patients. Currently, there are no established guidelines for the evaluation and treatment of adult patients who have had KD. We report 4 most probable cases of KD missed in childhood and presented as acute coronary syndrome in adulthood.

Abstract
AIM Local anesthetic toxicity remains one of the most dreaded complications of the intravenous regional anesthesia (IVRA) technique. It results from the sudden release of a large amount of local anesthetic (LA) into the systemic circulation. This release can occur when the tourniquet deflates accidentally during the procedure or when it is deflated intentionally at the end of the procedure to terminate the anesthesia. The forearm tourniquet IVRA technique may offer distinct advantages over the conventional upper arm tourniquet IVRA technique. Use of a forearm tourniquet allows the dosage of local anesthetic to be decreased to almost half of what is required with an upper arm tourniquet, and the incidence of tourniquet pain has been reported to be less with forearm tourniquet. In this study, authors assessed the clinical efficacy of administering IVRA with lidocaine plus ketorolac using either a forearm or upper arm tourniquet. METHODS Upper arm IVRA was established using 0.5% lidocaine at a dose of 3 mg/kg with ketorolac at 0.3 mg/kg. Forearm IVRA was established using 0.5 % lidocaine at a dose of 1.5 mg/kg with ketorolac at 0.15 mg/kg. Quality of surgical anesthesia, onset, duration of sensory block and postoperative surgical pain and analgesic use were recorded and assessed. The incidence of local anesthetic toxicity and local complications due to the tourniquet were also recorded. RESULTS Surgical anesthesia was assessed as excellent or good (grade 0/1) in all 20/20 patients who received IVRA using an upper arm tourniquet and in 19/20 patients who received IVRA using a forearm tourniquet (P=1.00). Onset as well as regression of sensory block was similar in both the groups. Post operative VAS scores at 30 min and 60 min were statistically comparable between the two groups, as was the analgesic use in the first 24 h. CONCLUSIONS In conclusion, forearm IVRA provides effective perioperative anesthesia and analgesia. The technique results in a similar clinical profile as upper arm IVRA while using half the dose of both lidocaine and ketorolac.

Abstract
BACKGROUND The Euro Heart Survey on diabetes and heart has demonstrated high prevalence of latent glucose abnormalities in non-diabetic patients with coronary artery disease (CAD) in the European population. The aim of our survey was to assess the prevalence of latent abnormal glucose regulation in adult non-diabetic CAD patients in India. METHODS AND RESULTS Seven centers distributed across India recruited 350 patients. The diagnosis of CAD was done by coronary angiography showing >50% stenosis in any major epicardial coronary artery or its branches. Oral glucose tolerance test (OGTT) and fasting glucose levels were used to characterize glucose metabolism. Venous plasma glucose was measured before (fasting) and 2 hours after ingestion of glucose. Impaired fasting glucose (IFG) was defined as OGTT (0 minute)>or=100 mg/dl but <126 mg/dl and OGTT (2 hours)<140 mg/dl. Impaired glucose tolerance (IGT) was defined as OGTT (0 minute)<126 mg/dl and OGTT (2 hours)>or=140 mg/dl but <200 mg/dl. Of the 350 patients studied, 176 (50.28%) had impaired glucose regulation (IFG-28 [8%]; IGT-148[42.28%]) and 75 (21.42%) had newly detected Diabetes. In all 251 (71.7%) patients with CAD had previously undetected abnormal glucose regulation. CONCLUSION This survey demonstrates the presence of abnormal glucose regulation in almost three quarters of the non-diabetic Indian CAD patients. OGTT should be recommended as routine screening test for detecting latent glucose abnormalities in all CAD patients.

Platelet glycoprotein IIb/IIIa inhibition using eptifibatide with primary coronary stenting for acute myocardial infarction: a 30-day follow-up study. Catheter Cardiovasc Interv 2002; 57:497-503.

Abstract
The results of primary coronary stenting for acute myocardial infarction (AMI) have been reported to improve significantly with the concomitant administration of platelet glycoprotein IIb/IIIa inhibitor abciximab. There are, however, no data available with the use of eptifibatide, a more cost-effective, small-molecule GP IIb/IIIa blocker with a shorter half-life. In a prospective multicenter feasibility and efficacy study, we assigned 55 consecutive patients with AMI being taken up for primary stenting to receive eptifibatide just before the procedure (two boluses of 180 microg/kg 10 min apart and a 24-hr infusion of 2 microg/kg/min). Clinical outcomes were evaluated at 30 days after the procedure. The angiographic patency of the vessel with TIMI flow rates, TIMI myocardial perfusion (TMP) grade, and corrected TIMI frame counts were assessed at the end of procedure and before hospital discharge. At 30 days, the primary endpoint, a composite of death, myocardial infarction, and urgent target vessel revascularization (TVR) was seen in 12.7% of patients. The TIMI 3 and TMP grade 3 flow, which was seen in 93% and 86% of patient, respectively, at the end of the procedure, declined to 86% and 78%, respectively (P < 0.05) before hospital discharge. Corrected TIMI frame counts also decreased from 25.7 +/- 7.2 to 22.9 +/- 6.8 (P < 0.05). There were five (9.1%) instances of subacute thrombosis (SAT) presenting as AMI, needing urgent TVR in all, within 3-5 days of the primary procedure. No excessive bleeding complication, directly attributable to the use of eptifibatide, was observed. The study was terminated prematurely because of an unacceptable SAT rate. Administration of eptifibatide along with primary stenting for AMI is associated with a high TIMI 3 and TMP grade 3 flow acutely. However, these flows decline significantly before hospital discharge and lead to a high rate of SAT. The dosage and duration of infusion of eptifibatide in this setting needs further evaluation.

Abstract
Previously, the enzymes for trehalose synthesis that are present in Escherichia coli were demonstrated in Bradyrhizobium japonicum and B. elkanii. An alternative mechanism recently reported for the synthesis of trehalose from maltooligosaccharides was considered based on the fact that high concentrations of sugars in liquid culture stimulated the accumulation of trehalose. An assay for the synthesis of trehalose from maltooligosaccharides using crude, gel-filtered protein preparations was developed. Analysis of a variety of the Rhizobiaceae indicates that the "maltooligosaccharide mechanism" is present in B. japonicum, B. elkanii, Rhizobium sp. NGR234, Sinorhizobium meliloti, R. tropici A, R. leguminosarum bv viciae, R. I. bv trifolii, and Azorhizobium caulinodans. Synthesis of trehalose from maltooligosaccharide could not be detected in R. tropici B or R. etli.

Abstract
We tested the hypothesis that activation of protein kinase C (PKC) isoforms in pressure-overload heart failure was prevented by angiotensin-converting enzyme (ACE) inhibition, resulting in normalization of cardiac sarcoplasmic reticulum (SR) Ca2+ ATPase (SERCA) 2a and phospholamban protein levels and improvement in intracellular Ca2+ handling. Aortic-banded and control guinea pigs were given ramipril (5 mg. kg-1. day-1) or placebo for 8 wk. Ramipril-treated banded animals had lower left ventricular (LV) and lung weight, improved survival, increased isovolumic LV mechanics, and improved cardiomyocyte Ca2+ transients compared with placebo-treated banded animals. This was associated with maintenance of SERCA2a and phospholamban protein expression. Translocation of PKC-alpha and -epsilon was increased in placebo-treated banded guinea pigs compared with controls and was attenuated significantly by treatment with ramipril. We conclude that ACE inhibition attenuates PKC translocation and prevents downregulation of Ca2+ cycling protein expression in pressure-overload hypertrophy. This represents a mechanism for the beneficial effects of this therapy on LV function and survival in heart failure.

Abstract
Balloon dilatation was performed in two cases of supravalvular aortic stenosis with variable results. There was remarkable reduction in gradient in the patient with membranous obstruction and the benefits are sustained at 18 months follow-up. The patient with hour-glass obstruction had only a partial success with reappearance of obstruction within 1 week. Balloon dilatation may emerge as a viable treatment modality for membranous obstructions. However, a large study is needed to establish the place of this procedure.

Abstract
A plasmid containing transposon Tn3 is immune to further insertions of Tn3. This phenomenon works in cis and is referred to as transposition immunity. We have used the ability of Tn3 to form cointegrates between two plasmids to develop a quantitative assay to detect transposition immunity. Presence of Tn3 on both the plasmids reduces the cointegration frequency to less than 1/100 of parental. Using this assay, we have determined that (i) tnpR is not required for immunity, (ii) only the terminal 38 base pairs of Tn3 need be present to confer immunity, and (iii) other parts of Tn3 appear not to confer immunity.
