Correlation study of socio-demographic factors like gender, age, body mass index and some cardiovascular parameters in hypertensive subjects of Yenagoa, Bayelsa state, Nigeria

Hypertension is defined as a sustained elevated arterial pressure to a level that places the patient at increased risk of organ damage. It is a non-communicable disease which constitutes a public health importance. Its risk factors include advancing age, high salt intake, excessive alcohol consumption and stress. This study was performed to determine the correlation between some socio-demographic factors like gender, age, body mass index (BMI) and some cardiovascular parameters in hypertensive patients of Yenagoa, Bayelsa State, Nigeria. The study was carried out with 400 hypertensive subjects, whose blood pressures were determined using palpatory and auscultatory methods. The gender, age and body mass index of the subjects were also determined. Statistical analysis was done using Z-statistics. We found a significant positive relationship between the age and cardiovascular parameters. Gender and BMI were found to have an insignificant positive correlation with the cardiovascular parameters. The study demonstrated that body mass index, age and gender are closely associated with cardiovascular parameters, though the degree of correlation differed. The risk of hypertension is therefore expected to be higher among the aged and populations who are overweight or obese.

Perception of data quality and electronic health information system acceptance, reliability and satisfaction: A study at tertiary care hospital in Saudi Arabia

Electronic health information systems (EHIS) are considered a backbone for healthcare planning and quality services. This study was designed to explore the acceptance, reliability, and satisfaction of the end users' experience with the hospital electronic health information system. We also investigated the perception of data quality by the users who were directly involved in data entry. We conducted a questionnaire based cross-sectional survey to collect quantitative data from different EHIS users. The questionnaire contained six sections: demographic user information; general HIS assessment; accessibility and availability of computer terminals in the hospital; EHIS and the patient care; user satisfaction with the HIS and perception of data quality. Desktop computers were available throughout the hospital, but the hospital was lacking handheld computers or computers on wheels. Participants of the study were satisfied with the data entry and retrieval process but they were lacking job training related to troubleshooting. EHIS users were not aware and prepared for the downtime of the system and procedures were also not clear to them. Regarding the perception of data quality, most of the participants responded that data is of adequate quality. There is a need for proper technical support and enhance the hospital's networking speed for better response. Laptops and hand-held computers are the need of time for data entry in critical situations and during wards visit. This can also enhance the quality of data, and reduce the chances of data loss.

Evaluation of renal functions tests among Sudanese healthy pregnant women attending antenatal care (ANC) at The National Ribat University Hospital in Khartoum State in 2019

Pregnancy involves remarkable physiological changes and the functional impact of pregnancy on the kidney physiology is widespread involving practically all aspects of kidney functions. The aim of this study was to evaluate the renal functions in Sudanese healthy pregnant ladies during different trimesters. A cross sectional study was carried out during July to October 2019 on Sudanese healthy pregnant ladies attending antenatal care at the National Ribat University Hospital in Khartoum State. The study covered 60 healthy pregnant ladies (20 for each trimester). The purpose of the study was explained to all participants and they were assessed after taking their consent. Blood pressure (BP) and body mass index (BMI) were measured by standard techniques. A sample of five ml venous blood was taken in a suitable blood container for measurement of urea and creatinine using a fully automated Mindray BS-300 Chemistry Analyzer (Mindray Bio-Medical Electronics Co., Ltd., Shenzhen, China). The data was analyzed using SPSS version 25 (IBM SPSS Inc.,Chicago, IL, USA), t-test was used to compare the statistical significant (p value ≤ 0.05 was considered statistical significant). The mean age of participants was 26.6±5.3 years with the range of 18-37 years. The mean BMI was 25.7±3.6 with the range of 18-31. The mean urea in the first, second and third trimester was 13.4, 13.9 and 13.2 mg/dl respectively with no statistically significant variation. The mean creatinine in the first, second and third trimester was 0.6, 0.6 and 0.5 mg/dl respectively with no statistically significant variation. To conclude, there was no significant variation of serum urea and creatinine during three trimesters of pregnancy in healthy pregnant women.

Resting heart rate variability in regular yoga practitioners - A cross-sectional study

Heart rate variability (HRV) is a useful and powerful non-invasive tool for quantitative assessment of cardiac autonomic function. Recent studies have shown that low heart rate variability is an indication of increased risk for cardiac diseases and sudden cardiac death. Yoga has been associated with improved cardio-respiratory performance. Thirty male regular yoga practitioners doing yoga for more than 3 years, age between 25-45 years (yoga group) and 30 male non-yoga practitioners, age-matched (control group) were included. A computerized Niviqure ECG system with HRV software was used for heart rate variability recording. Our results show that frequency-domain parameters like LF power, LF n.u, and LF/HF ratio were significantly lower in yoga group compared to control group. Time-domain parameters like mean RR, NN50, pNN50 were significantly higher in yoga group compared to control group. We conclude that the yoga increases heart rate variability by optimizing the autonomic functions, which is a good indicator of cardiac autonomic activity during rest.

Dyslipidemia is the hallmark of the metabolic syndrome in postmenopausal women

The incidence of cardiovascular diseases (CVD) increases after menopause and may be due to changes in the plasma lipid-lipoprotein levels that occur following menopausal transition. Physiological estrogen withdrawal during menopause plays a major role in abnormal lipid metabolism such as elevated low-density lipoprotein concentration. The aim of this study was to determine the relationship between dyslipidemia and the causative factors of metabolic syndrome in postmenopausal women. In this cross-sectional study, 290 postmenopausal Sudanese women were included. Lipid profiles were measured by spectrophotometer, estrogen hormone determined by ELISA, insulin resistance determined by HOMA-2 calculator and lipid accumulation product was calculated by the following equation (waist circumference in cm X triglyceride concentration in mM). The results revealed that total cholesterol, triglycerides, low-density lipoprotein levels and very low-density lipoprotein levels were significantly higher in the postmenopausal women with metabolic syndrome (MS) in comparison to those without the MS. Elevated total cholesterol levels were seen in 51.7 %, elevated triglycerides were seen in 49.7% and elevated low-density lipoprotein levels were seen in 29.3% whereas reduced high density lipoprotein levels were seen in 16.89% of the postmenopausal women. Total cholesterol, triglycerides and very low-density lipoprotein values showed a significant positive correlation with insulin resistance and lipid accumulation and a significant negative correlation with the estrogen hormone level. In addition, high density lipoproteins showed a significant negative correlation with lipid accumulation levels.

Effect of tea and coffee consumption on the blood pressure, pulse wave velocity and aortic pressures in young healthy individuals

Caffeine present in tea and coffee, the most commonly used beverages, has been implicated to have long term effects on cardiovascular system. The aim of this study was to document the acute and chronic effects of tea and coffee consumption on blood pressure, pulse wave velocity and aortic pressures in young, healthy individuals. This observational study was conducted on 86 healthy MBBS student volunteers of both genders between the age group of 18-27 years. Cardiovascular parameters (heart rate, peripheral blood pressure, central blood pressure, pulse wave velocity, augmentation pressure) were measured using PeriScope. Participants were divided into 3 groups based on their history of consuming tea/coffee/both/none. Data collected was analyzed using SPSS 17.0. ANOVA or Welsh test of equality of means was used for knowing the differences for scale variables. Paired sample t test was used to know the acute effect of coffee consumption among group 1 participants in a before-after design. In regular tea consumers, the bilateral brachial SBP, DBP and MAP were significantly higher than individuals who did not consume tea regularly; similar results in these parameters were also observed in regular coffee drinkers. However the lower limb arterial parameters were not markedly differently in tea/coffee group compared to non-drinkers. In both tea and coffee group, AoSP and AoDP were significantly higher than non-drinkers. Additionally, coffee drinking has acute stimulatory effects on CVS as evident by increase in peripheral and central vascular parameters.
