RESUMO

BACKGROUND Coronavirus disease 2019 (Covid-19) is an evolving disease with newly generated evidence related to the clinical management of Covid-19 patients. We aimed to compare two online learning schedules for disseminating new cardiopulmonary resuscitation (CPR) guidelines in terms of knowledge gain and acceptability among nurses. METHODS In a prospective randomized controlled study, 61 nurses trained in comprehensive cardiopulmonary life support (CCLS) were randomized to synchronous (n=31) and asynchronous learning groups (n= 30). The enhanced training module on CPR (ETMCPR) prepared by a team of experts was used to impart training to the nurses. Baseline data and pre-intervention knowledge of participants were collected using a structured demographic sheet and knowledge questionnaire (25 items) in a google form. Nurses in the synchronous group were provided training using ETMCPR through a licensed Zoom platform, while the nurses in the asynchronous group had access to the uploaded ETMCPR module in the e-learning platform. At the end of the intervention, the knowledge of the nurses was assessed along with their acceptability to the online learning schedule. RESULTS Both schedules of online learning were effective in improving the knowledge scores of the nurses (11.93 [3.26] v. 21.15 [1.90], p=0.01 and 11.71 [3.12] v. 20.32 [1.71], p=0.01). The mean acceptability scores of nurses in the asynchronous group were statistically lower than in the synchronous group (38.93 [2.50] v. 42.5 [3.08], p=0.007). CONCLUSION Both synchronous and asynchronous schedules of online learning were effective in disseminating updated CPR guidelines; however, nurses in the synchronous group were more satisfied with the learning schedule.

RESUMO

Background: Previous epidemiological studies suggest an association between psoriasis and metabolic syndrome and risk of subclinical atherosclerosis. However, there is a paucity of data in the Indian population on these associations. Objectives: To evaluate the prevalence of metabolic syndrome and subclinical atherosclerosis in patients with chronic plaque psoriasis compared to healthy controls and to correlate the prevalence of metabolic syndrome with severity of psoriasis. Methods: A hospital-based cross-sectional study was performed on 140 patients with chronic plaque psoriasis and 140 controls. Psoriasis was categorized as mild, moderate and severe based on psoriasis area and severity index (<10, 10–14 and ≥15, respectively) and as disease of short (<1 year), intermediate (1–3 years) and long duration (>3 years). In all patients and controls, body mass index was calculated, blood pressure and waist circumference were measured and fasting blood sugar and lipid profi le were estimated. Metabolic syndrome was diagnosed by the presence of 3 or more of the modifi ed National Cholesterol Education Program’s Adult Treatment Panel III criteria. A subset of 30 psoriatic patients and 30 healthy controls were selected by the systematic sampling method for cardiac evaluation including electrocardiography, echocardiography and carotid intima-media thickness measurement. Results: The prevalence of metabolic syndrome was signifi cantly more in psoriatic patients than in controls (39.3% vs. 17.1%, odds ratio = 3.13). Psoriatic patients also had a signifi cantly higher prevalence of hypertension, abdominal obesity and diabetes. There was a signifi cant trend to increase in prevalence of metabolic syndrome, hypertension and type 2 diabetes with increased severity and longer duration of the psoriasis. Patients with psoriasis had signifi cantly higher carotid intima-media thickness (mean 0.61 mm ± 0.01 mm vs. 0.37 mm ± 0.01 mm) than controls. Limitation: This was a hospital-based cross-sectional study with a relatively small sample size. A prospective study with a larger sample would have validated the results further. Conclusion: There is a signifi cantly higher prevalence of metabolic syndrome in psoriasis patients as compared to controls; the prevalence of metabolic syndrome and its components increases with severity and duration of psoriasis. There is a higher prevalence of subclinical atherosclerosis in patients with psoriasis thus increasing the risk of cardiovascular disease. We suggest that patients with moderate to severe psoriasis be screened routinely for metabolic syndrome and cardiovascular disease and encouraged to correct modifi able cardiovascular risk factors.

RESUMO

Recent advances in molecular biology have advanced our understanding of the genetic substrate predisposing to sudden death, especially in monogenic disorders. Numerous ion channels along with membrane structural proteins have been extensively investigated for their role in the genesis of serious ventricular tachyarrhythmias. The complex interplay of various biological pathways culminating in the more prevalent form of sudden death due to coronary artery disease however still remains to be unraveled. The concept of multi-factorial causation of arrhythmias where a second clinical or environmental factor is necessary for expression of an underlying genetic susceptibility to ventricular arrhythmias is a serious possibility. This article briefly outlines the current understanding about the role of genetics in sudden cardiac death.

RESUMO

Surgical or interventional perforation of atretic pulmonary valve as initial palliative procedure has been advocated in patients with pulmonary atresia with an intact ventricular septum. We report two infants with pulmonary atresia and intact ventricular septum, who were treated by radiofrequency perforation and balloon dilatation.

RESUMO

Recognising ventricular origin of a broad QRS tachycardia helps to appropriately identify and manage patients with ventricular tachycardia (VT) in the emergency. Relatively simple clinical and ECG clues help in reaching the correct diagnosis in the majority of patients. Management strategies vary with the clinical diagnosis and an implantable cardioverter defibrillator (ICD) is indicated for chronic prophylactic therapy in patients with coronary artery disease and serious ventricular arrhythmias, especially in those with ventricular dysfunction. The role of this device in patients with stable VT and ejection fractions > 0.35 deserves closer scrutiny. Radiofrequency ablation mostly plays an adjunctive role. Anti-arrhythmic drugs (amiodarone/sotalol and beta-blockers) are required to prevent frequent recurrences. A hybrid approach combining all these therapeutic modalities is often needed. Prognosis in patients with specific VT syndromes such as right ventricular outflow VT, left ventricular fascicular VT and left ventricular outflow VT is excellent with drugs. Radiofrequency ablation is curative in such syndromes.

RESUMO

BACKGROUND: Coronary angiography using 4 F catheters may reduce access-site complications and enable early ambulation, although earlier studies suggested that the quality of images may be an issue of concern. METHODS AND RESULTS: To ascertain the quality of angiographic images and safety of early ambulation, 500 patients were randomized to coronary angiography with either 4 F or 6 F catheters. Procedural characteristics, angiographic quality scores and results of ambulation were analyzed in the two groups. Patients in the 4 F group were mobilized at 2 hours post-procedure while those in the 6 F group were ambulated at 6 hours. There was no procedure-related complication in either group. The procedure was successfully completed in 250 of 252 patients randomized to the 4 F group. In two patients in the 4 F group, sheaths were upgraded to 6 F to complete the procedure, as difficulty was encountered in hooking the coronary ostium with a 4 F Judkin's catheter. Coronary angiographic quality scores in these two groups were comparable. Angiographic scores for the 4 F and 6 F groups for the left coronary artery averaged 4.45+/-0.5 and 4.58+/-0.3 (p>0.1), respectively. The right coronary artery scores averaged 4.30+/-0.4 and 4.35+/-0.2 (p>0.1) in the 4 F and 6 F groups. Angiographic scores for the left ventricular angiogram averaged 4.22+/-0.1 and 4.44+/-0.3 (p>0.1) in the 4 F and 6 F groups, respectively. None of the angiograms were assigned a score of <3.0 (not diagnostic). The total contrast volume consumed in the two groups was also equivalent. There were no groin-related complications in the 4 F group although these patients were ambulated 2 hours after the procedure. CONCLUSIONS: Coronary angiography performed with a 4 F catheter is a safe and reliable procedure. The quality of image obtained with a 4 F catheter is equivalent to that obtained with a 6 F catheter. Early ambulation at 2 hours is feasible without compromising safety.
