Lipid Profile in Postmenopausal Diabetic Female.

Background and Aims: Postmenopausal diabetic female are at increased risk of cardiovascular disease. The objective of this study was to study their lipid profile and prevalence of dyslipidemia and assess relation of control of lipid components with various risk factors.&#x0D; Methods: A cross sectional prospective study conducted at Shahid Gangalal National Heart Centre from 15th July 2020 to 14th October 2020 including 109 postmenopausal diabetic female. Detailed history along with clinical examination were conducted. Fasting lipid profile and other relevant investigations were obtained.&#x0D; Results: Mean age of participants was 63.48±9.26 years. Mean age of menopause was 48.59±1.88 years. A total of 37 (33.9%) were hypertensive, 17 (15.6%) were smoker, 67 (61.5%) were physically inactive. A total of 91 (83.5%) were non-vegetarian. Thirty eight (34.9%) had their blood sugar controlled with hemoglobin A1c of &lt;7%. The mean total cholesterol and high density lipoprotein were 5.21±0.97 mmol/l and 1.02±0.13 mmol/l. Similarly mean triglyceride and low density lipoprotein were 2.24±0.75 mmol/l and 3.04±0.12 mmol/l. Dyslipidemia was present in 82.6%. Significant correlation of control of blood sugar with total cholesterol control status (R=0.28, P=0.01), low density lipoprotein control status (R=0.38, P=0.01), high density lipoprotein control status (R=0.36, P=0.04) and triglyceride control status (R=0.30, P=0.04) were seen.&#x0D; Conclusion: Dyslipidemia was common in post menopausal diabetic female. Blood sugar control status showed significant correlation with lipid profile parameters. A good sugar control and evaluation for lipid abnormalities is recommended in postmenopausal diabetic female.</jats:p

Thermodynamic cycles and their application in protein targets

A key part of drug design and development is the optimization of molecular interactions between an engineered drug candidate and its binding target. Thermodynamic characterization provides information about the balance of energetic forces driving binding interactions and is essential for understanding and optimizing molecular interactions. Comprehensive thermodynamic evaluation is vital in the drug development process to speed drug development towards an optimal energetic interaction profile while retaining good pharmacological properties. Practical thermodynamic approaches, such as enthalpic optimization, thermodynamic optimization plots and the enthalpic efficiency index, have now been developed to provide proven utility in design process. Improved throughput in calorimetric methods remains essential for even greater integration of thermodynamics into drug design

Receptor thermodynamics of ligand–receptor or ligand–enzyme association

Experimental techniques that directly assess the thermodynamics of ligand–receptor or ligand–enzyme association, such as isothermal titration calorimetry, have been improved in recent years and can provide thermodynamic details of the binding process. Parallel to the continuous increase in computational power, several classes of computational methods have been developed that can be used to get a more detail insight into the mode and affinity of compounds (drug) to their target (off). Such methods are affiliated with a qualitative and/or quantitative assessment of binding free energies, and differently trade off speed versus physical accuracy. With the current wealth of available three-dimensional structures of proteins and their complexes with ligands, structure-based drug design studies can be used to identify the key ligand interactions and free energy calculations, and can quantify the thermodynamics of binding between ligand and the target of interest

Cardiovascular risk factors and clinical pattern in young Nepalese population with acute coronary syndrome presenting to a tertiary care center of Nepal

Background and objectives: Cardiovascular disease is a major health problem reaching epidemic proportions. Although Acute Coronary Syndrome (ACS) is an uncommon entity in the young, it constitutes a rising burden in the socioeconomic status of the country because of its impact on the economically productive age group. Early identification and control of the cardiovascular risk factors helps to prevent cases of Myocardial Infarction (MI) in young resulting in reduced health burden. Therefore, we aimed to assess clinical pattern and the prevalence of cardiovascular risk factors in the young and economically productive population of an underdeveloped country to lower the socioeconomic burden.Methods: A total of 60 patients presenting at the cardiology department of Manmohan Cardiothoracic Vascular and Transplant Center were included in our study after fulfilling the inclusion criteria. ACS was diagnosed by cardiac enzymes, electrocardiography, and echocardiography and coronary intervention was done in the cardiac catheterization room. Patients were followed up at 1 and 3-months and reassessed clinically and by echocardiography.Results: Mean age of presentation was 38.55 + 4.98 (SD) years. Over three-fourth of the patients were male (80%) and nearly three-quarter experienced ST-elevated MI (73%). Smoking was the most prevalent risk factor (67%), followed by dyslipidemia (40%), diabetes (32%), hypertension (30%), and obesity (13%). Most of the patients presented with single-vessel disease (65%), followed by double-vessel disease (18%), triple-vessel disease (12%), left main disease (3%), and minor coronary artery disease (2%).&nbsp;Conclusions: ACS in underdeveloped country is more common in male and single-vessel disease is the most common clinical pattern of ACS and smoking the most prevalent risk factor.</p
