Background. Menopause, a form of reproductive aging, is marked by many hormonal variations which cause imbalance in the oxidative processes resulting in onset of endothelial dysfunction leading to cardiovascular disease (CVD). We aimed to analyze the effect of oxidative stress in an early detection of CVD in all menopausal women both normolipidemic and hyperlipidemic. Methods and Results. Study included 523 menopausal women (265 CVD and 258 non-CVD). They were screened for lipid profile, serum malondialdehyde (MDA), serum LDL carbonyl protein, and serum superoxide dismutase (SOD). Pearson's correlation was observed between MDA and atherogenic index of plasma (AIP) in both normolipidemic (r = 0.650; p < 0.001) and hyperlipidemic (r = 0.207; p < 0.01) CVD group as compared to non-CVD menopausal women. Significant correlation was also observed between LDL carbonyl content and AIP in normolipidemic (r = 0.650; p < 0.001) and hyperlipidemic (r = 0.248; p < 0.01) CVD menopausal women as compared to non-CVD ones. Conclusion. Strong correlation between atherogenic index of plasma and oxidative stress in CVD menopausal women reveals oxidative stress as an effective prognostic tool for an early detection of cardiovascular risk.
Background: Till to date whether adiponectin AdipoQ gene variation (rs 1501299) is associated with cardiovascular disease, still remains controversial. Therefore, we aimed to relate the SNP (rs1501299) of adiponectin gene and oxidative stress in context to CVD in Punjabi women of North West India. Methods: In the present case-control study menopausal women with CVD as cases (n=265) and menopausal women without CVD as controls (n=258) were recruited. Genotyping of rs1501299 single nucleotide polymorphism of adiponectin gene was carried out by RFLP-PCR analysis. Biochemical parameters were analyzed according to the standard procedures. Results: Distribution of homozygous TT genotype of normolipidemic (p=0.001) and hyperlipidemic (p=0.001) women with CVD were significantly higher as compared to women without CVD. rs1501299 T allele carriers with CVD also showed significant (p=0.001) higher frequency distribution as compared to women without CVD. Under recessive model of inheritance TT mutant type homozygotes conferred ̴ 9 fold higher risk [p=0.001; OR= 9.60 (2.92-31.58)] towards CVD susceptibility for MDA>1.50; ̴ 11 fold higher risk [p=0.007; OR= 11.11 (1.49-82.83)] towards CVD for LDL carbonyl protein>15.04 and ̴ 9 fold higher risk [p=0.001; OR= 9.75 (2.30-41.22)] towards CVD susceptibility for SOD≤5.55. Under logistic regression analysis oxidative stress and TT genotype were significantly correlated with CVD. Conclusion: Our study revealed significant association of AdipoQ (rs1501299) gene polymorphism and oxidative stress with cardiovascular disease in Punjabi women of North West India. However, additional studies are required to support these findings. Keywords: AdipoQ gene, Association, Cardiovascular disease, MDA, RFLP-PCR, SOD
Summary Background: COVID-19 is caused by a novel coronavirus, named severe acute respiratory syndrome coronavirus2 (SARS-CoV-2). The foremost predominant complication of SARS-CoV-2 is arterial hypoxemia thereby disturbing lung compliance, requiring mechanical ventilation. The aim of the current research study is to analyze role of ABG as a valuable assessment tool of disease severity in SARS-CoV-2 patients. Methods: 170 arterial blood samples were collected from patients admitted in Intensive Care Unit (ICU) of Sri Guru Ram Das Charitable Hospital, Amritsar. They were analyzed for arterial blood gas using ABG analyzer. Parameters of ABG such as pH, pCo2, HCO3, O2 saturation, ionized calcium (iCa) and calculated ionized calcium (at pH 7.4) was calculated for all the samples. Results: Continuous variables were described as medians with interquartile ranges (IQRs) and categorical variables as percentages and frequencies. Spearman correlation test was done for calculation of correlation between pH and other ABG parameters. Analysis of arterial blood gas revealed significant negative correlation (p<0.05) between pH and pCO2 and significant positive correlation (p<0.05) between pH and HCO3 and between pH and delta ionized calcium. Low levels (98.2%) of ionized calcium were observed while monitoring the ABG findings though weak negative correlation (p<0.05) was observed between pH and iCa. Conclusion: Our study suggests that ABG analysis acts as a momentous indicator for critically ill patients admitted in Intensive Care Unit (ICU). Estimation of iCa in this critical care setting acts as a distinctive biochemical feature of SARS-CoV-2 disease, as an initial assessment tool, for hypocalcemia.

Background: The incidence of cardiovascular complications may increase after menopause. Hypertension (HTN) is one of the most remarkable causes leading to heart disease. The increased prevalence of HTN is associated with aging, causing adverse cardiovascular events in postmenopausal elderly women. Objectives: The present study aimed to compare HTN with the increasing age of elderly postmenopausal women with cardiovascular disease (CVD) and then to find an association between estradiol (E2) levels and the increased prevalence of HTN in these women. Methods: The present cross-sectional study recruited 265 cases of menopausal women suffering from CVD and 258 controls as menopausal women not suffering from CVD. Serum E2 and serum follicle-stimulating hormone (FSH) were estimated by enzyme-linked immunosorbent assay kits. HTN was assessed in accordance with the guidelines of the Joint National Committee (VII) of high blood pressure. Anthropometric measurements such as weight, height, hip circumference, waist circumference (WC), waist-hip ratio, and body mass index (BMI) for all menopausal women were recorded according to the World Health Organization (WHO) (WHO) 2000 protocol. Results: Overall, cases of>45.1 years of the menopausal age group conferred more risk toward CVD as compared to cases of≤45 years of the menopausal age group. A significant positive correlation (P<0.05) was detected for E2 with HTN and obesity profile with increasing age at menopause. Conclusion: High prevalence of HTN irrespective of the early onset of menopause is one of the crucial risk factors for CVD. Our findings revealed a significant positive correlation of HTN with age at menopause>45.1 years, along with increased levels of E2. Women in this age group were observed to be obese.
