    Assessment of lead augmented vector left (aVL on surface electrocardiogram) for confirming atrioventricular nodal reentrant tachycardia
    (Medip Academy, 2024-07) Hamid, M. A.; Ahmed, M.; Islam, A. F. M. R.; Aktar, M. S.; Rahman, A.; Sonali, T. A.
    Background: Atrioventricular nodal reentrant tachycardia (AVNRT) stands as one of the most common forms of paroxysmal supraventricular tachycardia (PSVT), encompassing a wide spectrum of clinical presentations and diagnostic challenges. The aim of this study was to evaluate the assessment of lead aVL (surface ECG) for confirming AVNRT. Methods: This was a prospective observational study and was conducted at the Department of Cardiology and Electrophysiology, National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh during the period from February 2019 to January 2020. Results: In our study 41 patients (66.1%) had AVNRT and 21 patients (33.9%) had AVRT on the final evaluation. Total 33.9% of patients had aVL notch on ECG. Among patients who had AVNRT, 46.3% had an aVL notch and among patients who had AVRT, 9.5% had an aVL notch on ECG. The difference was statistically significant (p=0.004). Among 21 patients who had aVL notch on ECG, 6 (31.6%) male patients had AVNRT, 13 (64.8%) female patients had AVNRT, 1 (50%) male patients had AVRT and 1 (50%) female patient had AVRT. Conclusions: In conclusion, the interpretation of electrocardiographic criteria, including the aVL notch, plays a pivotal role in confirming the diagnosis of AVNRT and guiding therapeutic interventions.

    A Critical Review And Local Audit Of The Prevalence Of Mental Ill-Health In Heart Failure Patients
    (Innovare Academic Sciences Pvt. Ltd., 2020-05) Ahmed, M.; Morrissey, H.; Ball, P. A.
    Objective: To establish if depression results in poor adherence to therapy in patients with heart diseases. Methods: This concept scoping study was conducted in two phases; the first was a systematic review of the literature, and the second part was local data analysis. Statistical analysis was performed using RevMan® V.5.3 (Cochrane Community). Results: Patients who received multidisciplinary collaborative care showed significantly reduced major adverse cardiac outcomes in patients with cardiovascular diseases. They also demonstrated higher rates of self-reported remission of depression. The review also showed endpoint mortality after PCI was associated with patients having depression. Local population data showed that 26% of heart failure patients had mental ill health comorbidity, however, only 12% had a formal diagnosis recorded. Conclusion: Depression is associated with poor cardiac outcomes in patients with coronary artery disease. It is widespread in patients with cardiovascular disease and must be screened for throughout the management plan.

    Genetically Modified Crop vs Hybrid Crops and their Impact on Health and Environment
    (Sciencedomain International, 2022-12) Mahmuda, R.; Mondal, S.; Rahman, A.; Ahmed, M.; Parvin, S.; Ahmed, T.
    Genetically modified crop (GMC) is a technology which includes transferring Deoxyribonucleic acid (DNA) in plant cells. On the other hand, Hybrid Crops are naturally occurring crops but it also involves manmade crosses to have at least 15-20% higher yield potential over high yielding inbred crop varieties using almost the same level of inputs and also can perform better even under unfavourable environments like drought and saline condition. These days, hybrid crops are one of the most commonly consumed foods for humans. In line with this GM crops have high yield potential and adaptive capability under wide range of environments even under fragile ecosystems. There are different aspects of both these types of crops. Human consumption of these crops has been a highly debatable topic in recent times. In this study, a brief discussion on GM crops and hybrid crops will be presented. Additionally, a comparison between them, in terms of health and productivity, will also be discussed.

    A study to assess the quality of sleep among medical students of Mysuru, Karnataka, India
    (Medip Academy, 2023-05) Nair, R. K.; Ahmed, M.
    Background: Every individual requires a period of rest to enhance and empower his/her work ability. Adequate quality of sleep is a prerequisite for optimal functioning of the students� mind and body. Sleep problems are common in the general population. Medical students are one subgroup who are more vulnerable to poor sleep quality owing to multiple factors in their lifestyle. To assess the quality of sleep in a population of medical students of Mysore Medical College and Research Institute, Mysuru and to study the determinants affecting it. Methods: An institution-based cross-sectional study was conducted using convenience sampling among 132 medical students of Mysore Medical College and Research Institute. A pre-designed and pre-tested structured questionnaire developed using the Pittsburgh quality of sleep index (PQSI) Score and Epworth daytime sleepiness scale (EDSS) was used. The data collected was compiled in MS- Excel and analysed using statistical package of social sciences (SPSS)Version 20.0. Results: Out of 132 medical students who were enrolled in the study, 55.3% (73/132) had an abnormal PSQI score. Males had better quality of sleep compared to females. Abnormal PSQI scores were associated with stress, alcohol and smoking. Conclusions: Sleep quality plays a major role in maintaining a medical student抯 physical, mental and working capacity.
