Applicability of VICTORION-1 PREVENT Criteria to the US Population

Abstract Background VICTORION-1 PREVENT (V-1P) is an ongoing randomized clinical trial comparing inclisiran sodium 300mg every six months with placebo for primary prevention in patients with high cardiovascular (CV) risk. Purpose We evaluated the generalizability of V-1P trial enrollment criteria to the US population to understand the demographic and CV health characteristics of the trial target population. Methods We included data from the National Health and Nutrition Examination Survey (N=25,531, 2015-March 2020), a nationally representative sample of the US population. Enrollment criteria similar to V-1P were applied. Nonpregnant adults 40-79 years with low-density lipoprotein cholesterol (LDL-C) of 70-189 mg/dL were included. 10-year risk for CV disease was determined using the American Heart Association race-free 10-year PREVENT risk equations. Individuals with 10-year risk >20% or 7.5%-19.9% with two risk enhancing factors at baseline were included. Risk enhancing factors included elevated high sensitivity C-reactive protein (≥2 mg/L), inflammatory arthritis, estimated glomerular filtration rate <60 ml/min/1.73 m2, metabolic syndrome, or early family history of CV disease. Patients with history of atherosclerotic CV disease or liver disease were excluded. Estimates of demographics and health characteristics were nationally representative using survey weights. Results Among US adults, 21,576,506 (standard error [SE]: ±1,258,255) meet eligibility criteria for V-1P (weighted estimate). This represents 8.8% of all US adults or 15.1% of US adults 30-79 years. The V-1P eligible population had a mean age of 65.3 years (SE: ±0.5 years), and 55.0% (SE: ±2.5%) were female. Compared with the US adult population (≥18 years), V-1P eligible population had a higher mean body mass index (32.6 ± 0.3 kg/m2 vs 29.5 ± 0.2 kg/m2) and higher rates of obesity (61.0% ± 2.1% vs 40.0% ± 1.1%) (Table). V-1P eligible population also had higher mean systolic blood pressure (133.9 ± 1.0 mmHg vs 121.7 ± 0.3 mmHg), similar mean diastolic blood pressure (72.6 ± 0.8 mmHg vs 71.8 ± 0.2 mmHg), and higher rates of hypertension (85.8% ± 2.0% vs 45.9% ± 1.1%). Mean hemoglobin A1c percent (6.3 ± 0.1 vs 5.7 ± 0.02), fasting blood sugar (127.7 ± 1.9 mg/dL vs 109.2 ± 0.6 mg/dL), and diabetes rates (39.7% ± 2.6% vs 13.1% ± 0.7%) were higher in the V-1P eligible population. Mean low-density lipoprotein cholesterol (115.8 ± 1.5 mg/dL vs 110.2 ± 0.8 mg/dL) and fasting triglycerides (137.6 ± 5.0 mg/dL vs 110.4 ± 1.7 mg/dL) were higher, while mean high-density lipoprotein cholesterol was lower (49.9 ± 0.8 mg/dL vs 54.8 ± 0.4 mg/dL). The distribution of key CV risk factors is shown in the Figure. Conclusion V-1P enrollment criteria apply to many patients. These patients have significant cardiometabolic risk factor burden, and effective preventive therapies could have substantial health impact.

Active Choice Nudge to Increase Screening for Primary Aldosteronism in At-Risk Patients.

Primary aldosteronism (PA) is the most common cause of secondary hypertension, yet screening remains startlingly infrequent. We describe: 1) PA screening practices in a large, diverse health system, 2) the development of a computable phenotype for PA screening, and 3) the design and pilot deployment of an electronic health record (EHR)-based active choice nudge to recommend PA screening. A multidisciplinary team developed a multi-pronged intervention to improve PA screening informed by guidelines, expertise, and multivariable analyses of factors associated with screening. The intervention included EHR-based tools to automatically identify screen-eligible patients, an active choice nudge recommending screening for these patients, and screening result interpretation. The intervention was piloted across two primary care practices for seven months. Screening frequencies were compared to clinics not receiving the intervention. The baseline frequency of screening of eligible patients within one year was 1.4%. Higher mean systolic blood pressure (OR=1.4; p<0.001), more antihypertensive medications (OR=1.3; p=0.002), lower minimum serum potassium (OR=2.0; p=0.001), specialist care (OR=3.0; p<0.001), and Black race (OR=1.5; p=0.001) were associated with a higher likelihood of screening. The refined computable phenotype identified a subcohort with a higher frequency of positive screening (8.6% versus 4.1%; p=0.03). In a pilot study of an active choice nudge, a greater proportion of eligible patients were screened in the intervention clinics (16.4%) than in the non-intervention clinics (1.8%; p<0.001). PA screening rates are low. This pilot study suggests an EHR-based nudge leveraging a precise computable phenotype can dramatically increase appropriate PA screening.

The Impact of Smoking on Arterial Stiffness in Young Adults: A Prospective Analysis.

Arterial stiffness is a crucial factor in the pathogenesis of cardiovascular disease, often associated with aging. However, the impact of smoking on arterial stiffness is frequently underestimated. This study aims to investigate the intricate relationship between smoking and arterial stiffness to advance our understanding of and therapeutic approaches to cardiovascular health. A prospective analysis was conducted from January to July 2024, focusing on arterial stiffness parameters in a cohort of students from the Carol Davila University of Medicine and Pharmacy. Participants were categorized as smokers or non-smokers based on self-reported smoking status. The study endpoints included correlations between high pulse wave velocity, elevated peripheral and central systolic blood pressure, increased peripheral and central pulse pressure, and smoking status. These markers were assessed using an arteriograph device measuring the time difference between the initial forward pulse wave and the reflected pulse wave in the brachial artery to indirectly estimate the PWV using oscillometric pulsations. Our investigation, involving 102 young individuals aged 20 to 26 (69 females, 33 males), revealed that smokers exhibited significantly higher average values of arterial stiffness indicators compared to non-smokers. Current smokers had higher mean systolic blood pressure (130.65 vs. 123.05 mmHg), higher mean peripheral pulse pressure (53.19 vs. 45.64 mmHg), higher mean central pulse pressure (33.66 vs. 29.69 mmHg), and higher mean pulse wave velocity (5.27 vs. 5.03 m/s). The utilization of arterial stiffness markers as predictive tools offers opportunities for personalized treatment strategies, potentially enhancing cardiovascular health outcomes.

Abstract P158: Frailty and Sex are associated with Discordant Blood Pressure Measures among Very Old Adults: Results from the Atherosclerosis Risk in Communities (ARIC) Study

Background: Home blood pressure monitoring (HBPM) is increasingly used as a more accessible alternative to office blood pressure (BP). However, agreement between office and home BP among very old adults has not been characterized. Objective: To identify clinical factors related to discordance between office and home BP among very old adults. Methods: ARIC participants underwent 3 office BP measures, using an Omron HEM907XL after a 5-minute rest with a 60-second pause interval (2023). In addition, using Omron Series 10 BP7450, participants measured BP three times at home in the morning and evening after a 5-minute rest with a 60-second pause interval over an 8-day period. We subtracted mean home systolic BP (SBP) from mean office SBP to determine discordance and characterized it via Bland-Altman plots. We used adjusted linear regression to determine whether age, sex, obesity, diabetes, frailty, or hypertension medications, were associated with discordance. Results: Among 776 participants (59.3% female; mean age 84.1±3.9 [SD] years), we observed no difference between office and home SBP; however, bias increased with higher mean SBP ( Figure, Panel 1 ). Compared to home, office SBP was significantly lower among the oldest, male, and frail participants, and higher among female and robust participants ( Figure, Panel 2 ). Conclusion: In this population of very old adults, office and HBPM generated similar estimates of resting SBP. Nevertheless, resting SBP, sex, and frailty may result in discordant measures that could influence treatment decisions. Comprehensive BP monitoring, including office and HBPM, may be necessary for accurate hypertension diagnosis and management in these subgroups of very old adults.

Early Detection of Renal Complication in Children With Sickle Cell Disease: A Single Center Prospective Study.

This observational cross-sectional study aimed to identify predictors of renal complications in pediatric patients with sickle cell disease (SCD) at King Salman Armed Forces Hospital, Tabuk, Saudi Arabia, over six months from February 2023 to July 2023. The study evaluated microalbuminuria as an early indicator of renal injury and explored its correlations with clinical and laboratory parameters and abdominal ultrasound (US) findings. Included were pediatric patients aged 1 to 14 years with confirmed SCD, excluding those with acute infections or pre-existing renal diseases. Data from 100 patients' electronic medical records were analyzed using IBM SPSS Statistics for Windows, Version 26 (Released 2019; IBM Corp., Armonk, New York, United States), with a significance set at p ≤ 0.05. The mean age was 7.6 ± 3.3 years, with 51 males and 49 females; 11 were diagnosed with Hb-S-beta thalassemia. Hydroxyurea (HU) compliance was high, with only four non-compliant patients, though all took folic acid. Among 42 tested for albuminuria, all had negative results (<30 mg/g creatinine). A significant association was found between SCD diagnosis and kidney, ureter, and bladder (KUB) US results (p=0.008), with abnormal KUB findings more prevalent in the Hb-S-beta thalassemia group. Patients with abnormal KUB results had significantly lower mean weight (p=0.024). Additionally, Hb-S-beta thalassemia patients had lower mean weight than hemoglobin SS (HGSS) patients (p=0.04). Though not statistically significant, Hb-S-beta thalassemia patients had higher mean systolic blood pressure (p=0.053). Significant associations were identified between SCD diagnosis type and renal US results, with lower body weight emerging as a potential predictor of renal complications. High HU compliance and its impact on renal outcomes warrant further investigation. Routine monitoring of microalbuminuria and KUB US may aid early detection of renal complications in pediatric SCD patients. Further studies with larger sample sizes are recommended to validate these findings and develop comprehensive renal protective strategies.

Association of retinal image-based, deep learning cardiac BioAge with telomere length and cardiovascular biomarkers.

Our retinal image-based deep learning (DL) cardiac biological age (BioAge) model could facilitate fast, accurate, noninvasive screening for cardiovascular disease (CVD) in novel community settings and thus improve outcome with those with limited access to health care services. This study aimed to determine whether the results issued by our DL cardiac BioAge model are consistent with the known trends of CVD risk and the biomarker leukocyte telomere length (LTL), in a cohort of individuals from the UK Biobank. A cross-sectional cohort study was conducted using those individuals in the UK Biobank who had LTL data. These individuals were divided by sex, ranked by LTL, and then grouped into deciles. The retinal images were then presented to the DL model, and individual's cardiac BioAge was determined. Individuals within each LTL decile were then ranked by cardiac BioAge, and the mean of the CVD risk biomarkers in the top and bottom quartiles was compared. The relationship between an individual's cardiac BioAge, the CVD biomarkers, and LTL was determined using traditional correlation statistics. The DL cardiac BioAge model was able to accurately stratify individuals by the traditional CVD risk biomarkers, and for both males and females, those issued with a cardiac BioAge in the top quartile of their chronological peer group had a significantly higher mean systolic blood pressure, hemoglobin A 1c , and 10-year Pooled Cohort Equation CVD risk scores compared with those individuals in the bottom quartile (p<0.001). Cardiac BioAge was associated with LTL shortening for both males and females (males: -0.22, r2 = 0.04; females: -0.18, r2 = 0.03). In this cross-sectional cohort study, increasing CVD risk whether assessed by traditional biomarkers, CVD risk scoring, or our DL cardiac BioAge, CVD risk model, was inversely related to LTL. At a population level, our data support the growing body of evidence that suggests LTL shortening is a surrogate marker for increasing CVD risk and that this risk can be captured by our novel DL cardiac BioAge model.

Exploring the Relationship Between Serum Phosphate Levels and Carotid Intima-Media Thickness in Chronic Kidney Disease Patients: A Correlational Analysis.

Background Compelling observational data suggestthat heightened levels of fasting blood phosphate are linked to a higher likelihood of cardiovascular disease, spanning across both the general populace and individuals grappling with chronic kidney disease (CKD). This study aimed to explore the possible correlation between carotid intima-media thickness (CIMT) and blood phosphate levels among those afflicted with chronic renal dysfunction. Objective The primary goal of this study is to determine the potential association between blood phosphate levels and CIMT in patients with CKD. Methodology In the department of nephrology, prospective research was conducted among patients who had a history of CKD. Atotal of 30 patients were included, with 20 males and 10 females. Every case had a thorough physical examination and history. Every patient underwent a laboratory evaluation, which included measurements of the CIMT and renal function testing. At a distance of 1 cm from the carotid bulb, the CIMTwas measured using B-mode ultrasonography. After compilation, the data were examined. Results The majority of the patients, according to this study, were male and over 50 years old. The Stage II patients in the study had a higher mean systolic blood pressure; however, the difference was not statistically significant. Patients with Stage V (D) disease exhibited higher diastolic blood pressure, but not statistically significant. An increase in the mean serum creatinine level that was statistically significant was linked to Stage V (D) renal disease. A higher mean blood urea was linked to Stage V (D) sickness; however, this relationship was not statistically significant. There was no statistical difference in the mean serum calcium levelsbetween the different stages of renal disease. Higher mean blood phosphate levels were linked to Stage III renal disease, but not in a statistically meaningful way. Although it was higher in Stage IV kidney disease, the mean CIMT was not statistically significant between the stages of renal illness. Conclusions Although a positive correlation was shown, a direct relationship between serum phosphate levels was not established by this investigation. The severity of renal disease has been demonstrated to correlate with elevated serum phosphate levels.

The Role of Blood Pressure Control in Prevention of Hematoma After Blepharoplasty.

Hematoma formation after blepharoplasty is serious and potentially vision-threatening, with hypertension being the primary risk factor. The aim of this paper is to assess perioperative blood pressure trends and rates of complication in patients undergoing a strict blood pressure protocol designed to keep perioperative systolic blood pressure below 120 mmHg. A retrospective chart review was performed of 32 patients undergoing face lift with conomitant blepharoplasty from January 2015 to July 2018. For each patient blood pressure readings obtained before, during, and after surgery were reviewed. Two-sample one-tail T-tests were performed, and p values less than 0.05 were considered statistically significant. The mean systolic blood pressure (SBP) for all patients was highest intraoperatively. Patients with known hypertension had higher mean SBPs than patients without hypertension across all phases of care, with a statistically significant difference in immediate preoperative SBP (p=0.05). Males had a higher average blood pressure immediately postoperatively (p=0.05). A previous diagnosis of hypertension in females was associated with a higher immediate preoperative SBP (p=0.07) as well as age over 65 (p=0.07). The overall rate of complications was 37.5%. No patients experienced hematoma. This study demonstrated that keeping blood pressure below 120 mmHg after surgery was an effective method of preventing hematoma after blepharoplasty, even in patients concurrently on anti-coagulative medications. Special attention to blood pressure control should be shown to patients with known risk factors such as a previous diagnosis of hypertension, male sex, or age greater than 65.

Sex-specific associations between the environmental exposures and low-grade inflammation and increased blood pressure in young, healthy subjects

Long-term exposures to environmental factors including airborne as well as noise pollutants, are associated with cardiovascular risk. However, the influence of environmental pollution on the young population is controversial. Accordingly, we aimed to investigate the relationships between long-term exposures to different environmental factors and major cardiovascular and inflammatory parameters and biomarkers in young, healthy subjects. Representative sample of permanent residents of two cities differing in air and noise pollution levels, aged 15–21 years, were recruited. Krakow and Lublin, both located in southern Poland, were chosen in relation to their similarities in demographic and geopolitical characteristics, but differences in air pollution (higher in Krakow) and noise parameters (higher in Lublin). A total of 576 subjects were studied: 292 in Krakow and 284 in Lublin. All subjects underwent health questionnaire, blood pressure measurements and biomarker determinations. Inflammatory biomarkers, such as CRP, hs-CRP, fibrinogen as well as homocysteine were all significantly higher in subjects living in Krakow as opposed to subjects living in Lublin (for hsCRP: 0.52 (0.32–0.98) mg/l vs. 0.35 (0.22–0.67) mg/l; p < 0.001). Increased inflammatory biomarker levels were observed in Krakow in both male and female young adults. Interestingly, significant differences were observed in blood pressure between male and female subjects. Males from Krakow had significantly higher mean systolic blood pressure (127.7 ± 10.4 mm/Hg vs. 122.4 ± 13.0 mm/Hg; p = 0.001), pulse pressure (58.7 ± 8.9 mm/Hg vs. 51.4 ± 12.3 mm/Hg; p < 0.001) and lower heart rate (p < 0.001) as compared to males living in Lublin. This was not observed in young adult females. Long-term exposure to environmental factors related to the place of residence can significantly influence inflammatory and cardiovascular parameters, even in young individuals. Interestingly, among otherwise healthy young adults, blood pressure differences exhibited significant variations based on biological sex.

Association Between Hypertensive Disorders of Pregnancy and Interval Neurocognitive Decline: An Analysis of the Hispanic Community Health Study/Study of Latinos.

To evaluate whether hypertensive disorders of pregnancy, including gestational hypertension, preeclampsia, and eclampsia, are associated with cognitive decline later in life among U.S. Hispanic/Latina individuals. The HCHS/SOL (Hispanic Community Health Study/Study of Latinos) is a prospective population-based study of Hispanic/Latino individuals aged 18-74 years from four U.S. communities. This analysis included parous individuals aged 45 years or older who participated in the HCHS/SOL clinic study visit 1 (2008-2011) neurocognitive assessment and subsequently completed a repeat neurocognitive assessment as part of the Study of Latinos-Investigation of Neurocognitive Aging ancillary study visit 2 (2015-2018). Hypertensive disorders of pregnancy were assessed retrospectively by self-report of any gestational hypertension, preeclampsia, or eclampsia. Cognitive functioning was measured at both study visits with the Brief Spanish-English Verbal Learning Test, Digit Symbol Substitution, and Word Fluency. A regression-based approach was used to define cognitive decline at visit 2 as a function of cognition at visit 1 after adjustment for age, education, and follow-up time. Linear regression models were used to determine whether hypertensive disorders of pregnancy or their component diagnoses were associated with standardized cognitive decline after adjustment for sociodemographic characteristics, clinical and behavioral risk factors, and follow-up time. Among 3,554 individuals included in analysis, the mean age was 56.2 years, and 467 of individuals (13.4%) reported at least one hypertensive disorder of pregnancy. Individuals with hypertensive disorders of pregnancy compared with those without were more likely to have higher mean systolic blood pressure, fasting glucose, and body mass index. After an average of 7 years of follow-up, in fully adjusted models, gestational hypertension was associated with a 0.17-SD relative decline in Digit Symbol Substitution scores (95% CI, -0.31 to -0.04) but not other cognitive domains (Brief Spanish-English Verbal Learning Test or Word Fluency). Neither preeclampsia nor eclampsia was associated with neurocognitive differences. The presence of preeclampsia or eclampsia was not associated with interval neurocognitive decline. In this cohort of U.S. Hispanic/Latina individuals, gestational hypertension alone was associated with decreased processing speed and executive functioning later in life.

Exploring the association between PLGF and pregnancy outcomes

Introduction and Aim: Pregnancy demands vigilant fetal monitoring, yet traditional methods have limitations, leading to research on biomarkers like placental growth factor (PLGF) to enhance predictive accuracy for adverse outcomes. This investigation focuses on assessing the relationship between PLGF levels and pregnancy outcomes in women with suspected preeclampsia. Materials and Methods: A simple longitudinal design was employed, following pregnant women with suspected preeclampsia from enrollment until delivery. The study included 160 subjects, and their characteristics were recorded at admission. PLGF levels were measured, and pregnancy outcomes were assessed. Results: Among the study population, the distribution of pregnancies showed that 45.62% were in the first pregnancy, 40% in the second pregnancy, 11.85% in the third pregnancy, and 2.5% in the fifth pregnancy. The highest PLGF levels were observed in the fifth pregnancy group.Analysis revealed that subjects with NICU admission had a lower mean PLGF value compared to those without NICU admission. Among subjects with low PLGF levels, the mean baby weight was lower by approximately 5.3% when match up to those with normal PLGF levels.Regarding blood pressure, subjects with decreased PLGF levels had a higher mean systolic blood pressure in contrast to those with normal PLGF levels. Conclusion: Lower PLGF levels were associated with NICU admission, lower baby weight, and higher systolic blood pressure in women with suspected preeclampsia. These findings suggest that PLGF levels may have implications for pregnancy outcomes. Additional investigation with expanded sample sizes is necessary to authenticate these discoveries and look into the clinical relevance of PLGF in understanding and addressing preeclampsia.

Comparing Effectiveness and Safety of Intravenous Atropine with Topical Tetracaine in Preventing and Relieving Oculocardiac Reflex in Patients Undergoing Strabismus Surgery: A Randomized Clinical Trial

Abstract Background: Oculocardiac reflex (OCR) is one of the serious complications following surgical therapeutic procedures for strabismus. Various medications have been tested to prevent or mitigate this complication. We aimed to compare the effect of intravenous atropine and topical tetracaine on the incidence and severity of OCR in strabismus surgery. Materials and Methods: In this triple-blind randomized clinical trial study, 120 patients who were candidates for strabismus surgery were randomly assigned to receive intravenous atropine, topical tetracaine, or artificial tears as the control. The incidence of OCR and its severity along with the changes in hemodynamic conditions were compared across the groups. Results: The incidence rate of OCR in the groups receiving atropine, tetracaine, and the control was found to be 17.5%, 25.0%, and 32.5% in the releasing phase without any difference, respectively (P = 0.303); however, it was 2.5%, 7.5%, and 25.0%, respectively, in the cutting phase, indicating a lower rate in the group receiving tetracaine (P = 0.004). Similarly, there was no difference in the severity of OCR across the three study groups in the releasing phase (P = 0.666); however, in the cutting phase, OCR was revealed to be milder in the group receiving atropine as compared to other groups (P = 0.033). Prescribing atropine led to higher mean systolic blood pressure and mean arterial pressure during surgery. Conclusion: The injection of atropine can effectively reduce the incidence of OCR during strabismus surgery and reduce its severity if this reflex occurs.

Cardiometabolic risk profile of young and old adults with diabetes: Pooled, cross-sectional analysis of 42 national health surveys

AimsTo compare levels of cardiometabolic risk factors in young and old adults with diabetes. MethodsPooled analysis of 42 STEPS Surveys (n = 133,717). Diabetes was defined as self-reported diagnosis or fasting plasma glucose ≥ 126 mg/dl. There were two age groups: < 40 and ≥ 40 years. We summarized the mean levels of four cardiometabolic risk factors by country, sex and age group. ResultsIn 11 (men) and seven countries (women), the mean BMI seemed higher in young versus old adults; largest difference was found in men in Qatar (∼6 kg/m2). For waist circumference, such pattern was observed in two (men) and in three (women) countries; largest difference in men in Tuvalu (∼7 cm). Regarding systolic blood pressure, in one country (Myanmar) the mean was higher in young men with ∼8 mmHg difference. Women in the oldest group always had higher mean systolic blood pressure. For total cholesterol, in 13 (men) and five (women) countries the mean was higher in young adults (difference was always <1 mmol/l). ConclusionsLevels of cardiometabolic risk factors in young versus old adults with diabetes were heterogenous across 42 countries and depended on the risk factor. This calls to monitor cardiometabolic risk factors in young adults with diabetes.

Echocardiographic Assessment of the Left Ventricle in Young Prehypertensive Nigerians.

Prehypertension is associated with an increased risk of cardiovascular morbidity and mortality. This risk could partly be explained by the early compromise in left ventricular (LV) structure and function. This study investigated the LV geometry and function in young black prehypertensive subjects. This cross-sectional descriptive study was conducted at the Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria. Echocardiography-derived LV geometry and function were assessed using standardized methods. Prehypertensive subjects had higher mean systolic blood pressure (BP) (130.78 ± 3.57 mmHg vs 111.42 ± 3.54 mmHg, P<0.001), diastolic BP (79.32 ± 4.13 mmHg vs 66.39 ± 4.42 mmHg, P<0.001), body mass index (BMI) (26.24 ± 3.45 kg/m2 vs 22.20 ± 2.21 kg/m2, P<0.001), waist circumference (WC) (86.93 ± 8.73 cm vs 76.73 ± 6.66 cm, P<0.001), fasting blood glucose (FBG) (93.84 ± 7.28 mg/dl vs 90.08 ± 6.26 mg/dl, P<0.001), and dyslipidemia (21.5% vs 6%. P<0.001) compared to normotensive subjects. LV mass index (LVMI) was greater in prehypertensive subjects compared to normotensive subjects {male (106.84 ± 12.34 g/m2 vs 76.07 ± 10.25 g/m2, P<0.001); female (92.06 ± 8.80 g/m2 vs 66.53 ± 7.21 g/m2, P<0.001)}, with abnormal LV geometry recorded in 17.5%. Linear regression analysis showed that waist circumference, systolic BP, serum creatinine level, and urea level were determinants of LVMI. The prevalence of LV diastolic dysfunction was higher in prehypertensive subjects than in normotensive subjects (14.5% vs. 0.5%, P<0.001), with systolic BP {odds ratio (OR) 0.928, confidence interval (CI) 0.834 - 0.969; P=0.016)} and diastolic BP (OR 0.832, CI 0.722 - 0.958; P=0.011) being independent predictors. This study showed that prehypertension in young Black subjects was associated with altered LV geometry and impaired diastolic function, and these changes demonstrated linear progression with increasing systolic BP.

Evaluation of Blood Pressure in Children Treated with Ceftriaxone: A Case-Control Study

Background: In children, high blood pressure can develop into hypertension and its consequences during puberty and adulthood. High blood pressure in children is often secondary to other causes, including renal diseases. Nephrolithiasis is one of the causes of secondary hypertension. The extensive use of cephalosporins in hospitals, particularly ceftriaxone, can result in nephrolithiasis. Therefore, the purpose of this study was to assess the relationship between ceftriaxone treatment and elevated blood pressure in children. Method: The research was conducted as a case-control study over an 18-month period from 2018 to 2019. In this study, blood pressure was measured in 111 children aged 3-13 years who were hospitalized at Amir Kabir Hospital in Arak and received ceftriaxone for at least 48 hours. As a control group, 111 children who did not receive ceftriaxone had their blood pressure measured. The blood pressure levels and percentiles of children in the two groups were then compared. Result: In the case and control groups, the mean age was 5.1±1.61 and 6.04±2.4 years, and the mean height was 109.17±10.71 and 114.86±12.95 cm, respectively. A slightly higher mean systolic blood pressure percentile was observed in the case group (65.59±18.17) than in the control group (65.28±14.51) (P=0.112), and the mean diastolic blood pressure percentile was also slightly higher in the case group (58.89±18.88) than in the control group (54.85±19.28) (P=0.317). The difference in diastolic blood pressure was greater than in systolic blood pressure. However, these detected differences were slight and not statistically significant. Conclusion: This study showed no association between blood pressure levels and ceftriaxone treatment in children older than three years who received the medicine for at least 48 hours. However, additional research is suggested, focusing on the effects of the medicine at higher doses and over a longer period of time following administration.

Association of blood pressure variability and CT-based Leiden score in hypertension patients.

Blood pressure variability (BPV) obtained from ambulatory blood pressure monitoring (ABPM) has been demonstrated to accurately predict the risk of cerebrovascular events and death in hypertension patients, however, the association between BPV and the severity of coronary atherosclerotic plaque remains unclear. Patients with hypertension combined with suspected coronary artery disease (CAD) were collected, who underwent both ABPM and coronary computed tomographic angiography (CCTA) from December 2017 to March 2022. Patients were divided into three groups according to the Leiden score: low-risk group (Leiden score <5), medium-risk group (Leiden score 5-20), and high-risk group (Leiden score >20). The clinical characteristics of patients were collected and analyzed. Univariate Pearson correlation and multivariate Logistics regression were used to determine the association between BPV and the severity of coronary atherosclerotic plaque. A total of 783 patients were included, with the average age of (62.85 ± 10.17) years and 523 males. Patients in the high-risk group had higher mean systolic blood pressure (SBP), nighttime mean SBP and SBP variability (P < 0.05). Leiden score with low risk was associated with 24 h-SBP variability (r = 0.35, P = 0.006) and 24 h-diastolic blood pressure (DBP) loading (r = -0.18, P = 0.027). Leiden score with medium and high risk was associated with nighttime mean SBP (r = 0.23, P = 0.005), 24 h-SBP variability (r = 0.32, P = 0.003), and the decrease of nighttime SBP (r = 0.24, P = 0.019). Multivariate Logistic analysis showed that smoking [odds ratio (OR) = 1.014, 95% confidential interval (CI): 1.0-1.07, P = 0.03], diabetes (OR = 1.43, 95% CI: 1.10-2.26, P = 0.01) and 24 h-SBP variability (OR = 1.35, 95% CI: 1.01-2.46, P = 0.01) were independently associated with Leiden score with medium and high risk. Larger SBP variability in hypertensive patients indicates the higher Leiden score and consequently the more serious coronary atherosclerotic plaque. Monitoring SBP variability has certain significance for predicting the severity of coronary atherosclerotic plaque and preventing its progression.

Androgenetic Alopecia: Traditional Cardiovascular Risk Factors, Metabolic Syndrome, and Component Traits among Nigerian Adults

ABSTRACT Background: Androgenetic alopecia (AGA) has been linked to cardiovascular diseases (CVDs) and metabolic syndrome (MetS). Works on AGA, cardiovascular risk factors (CVRFs) and MetS are rare among Nigerians. Aim: This study set out to determine the relationship among CVRFs, MetS, and AGA. Subjects and Methods: This is a cross-sectional study done among adults who were 18 years and above in selected communities in Ogbomoso on 260 consenting AGA participants as well as 260 age controls without AGA. They were matched for age and sex using a multistage sampling method. Anthropometric measurements, fasting blood glucose, and lipid profile samples were collected. MetS was diagnosed using International Diabetes Federation criteria. Data were analyzed using IBM SPSS version 20. Ethical approval was gotten before commencement of the study (LTH/OGB/EC/2017/162). Result: Metabolic syndrome in AGA was higher than in controls (8.08% vs. 7.69%, p = 0.742). AGA was significantly associated with elevated mean systolic blood pressure (SBP) (p = 0.008), low High Density Lipoprotein (HDL-c) (p &lt; 0.001), alcohol intake (p &lt; 0.001), dyslipidaemia (p = 0.002), and sedentary lifestyle (p = 0.010). The correlates of AGA severity in male and female gender are age (p &lt; 0.001 and 0.009 respectively), SBP (p = 0.024) and abdominal obesity (p = 0.027) in male gender. Conclusion: AGA in Nigerians is associated with dyslipidaemia, alcohol intake, and sedentary lifestyle. AGA severity is related to age, higher mean SBP, abdominal obesity and low HDL-c in male and age, and Body mass index in females. Nigerians with AGA should be screened for dyslipidaemia and counseled against the use of alcohol and sedentary lifestyle.

P172 Metabolic disorders with non-alcoholic fatty liver disease in people with inflammatory bowel disease

Abstract Background Globally rising rates of obesity and consequent metabolic diseases have been reflected in the inflammatory bowel disease (IBD) population. Non-alcohol fatty liver disease (NAFLD) is a common liver disorder associated with obesity, that occurs more frequently in people with IBD. Methods A prospective single-centre cohort study. In total, we recruited 203 patients from our IBD service in a tertiary academic hospital. 7 participants were excluded due to later diagnosed non-NAFLD liver disease. Following informed consent, participants underwent a fibroscan for liver stiffness (LSM) and controlled attenuation parameter (CAP) measurement, and blood tests for HbA1c and fasting lipids. Basic demographics, past medical history, exercise measured on the Godin-Shepard Leisure Time Physical Activity Questionnaire, physical functioning on SF-36 Questionnaire, blood pressure, CAP and LSM were recorded. T-test and Fishers exact test were used to test for statistical significance as appropriate. Results Of the 196 IBD patients included, 34.7% (n=68/196) had a healthy BMI, 34.7% (n=68/196) were overweight (BMI≥25-29.9), and 30.6% (n=60/196) were obese (BMI≥30). Overall, 16.3% (n=32) had a CAP score &amp;gt;294dB/m consistent with NAFLD, and 2.55% (n=5) had a LSM &amp;gt;8.1kPa consistent with fibrosis. When compared to those without NAFLD, those with NAFLD had higher BMIs, 26.9 vs 32.3 p&amp;lt;0.05. They also had a much higher incidence of diabetes 28.1% vs 0% p=0.0001, higher overall rates of abnormal HbA1C (≥6%), 21.9% (n=7/32) vs 6.4% (n=10/156) p=0.0121, and higher rates of abnormal HbA1c without a diagnosis of diabetes 13% (n=3/23) vs 6.45% (n=10/155) p=0.4043. Additionally, they had non-significant higher mean systolic blood pressure and higher rates of diagnosed hypertension. Compared to those without NAFLD, the NAFLD cohort had higher rates of diagnosed hypercholesterolaemia 34.4% (n=11/32) vs 15.3% (n25/163) p=0.022 and there were higher rates of elevated total cholesterol (&amp;gt;5mmol/L) in those not previously diagnosed with hypercholesterolaemia, 42.9% (n=9/21) vs 31.8% (n=47/148) p=0.3292. Participants with NAFLD also had lower exercise scores 17 vs 24.9 p=0.03543, and lower scores for physical functioning 71.9 vs 83.2 p=0.00676. Of particular note, they had more than double the 10-year risk of myocardial infarction or death determined by the Framingham risk scores for hard coronary heart disease, 2.48% vs 5.75%, p=0.00012. Conclusion Our study shows that people with concurrent NAFLD and IBD have a significant cardiovascular risk profile. With increased awareness of this, metabolic syndrome conditions should be screened for and treatment initiated where appropriate, to decrease cardiovascular related mortality in this cohort.

Meta-analysis of TSH suppression therapy and the risk of cardiovascular events after thyroid cancer surgery.

To investigate the relationship between TSH suppression therapy and cardiovascular events in patients with thyroid cancer after surgery. Pub Med, Web of Science, and Embase databases were retrieved to collect studies related to the risk of cardiovascular events in patients treated with TSH suppression after thyroid cancer surgery. RevMan statistical software was used for meta-analysis. A total of 14 studies were included. The mean heart rate of patients after thyroid cancer surgery was higher than that of the control group (SMD=2.59, 95% CI: -0.37,.54), and the risk of atrial fibrillation was increased compared with the control group (RR = 1.52, 95%CI, 1.28-1.81; I = 63%). Ejection fraction and left ventricular end-diastolic diameter were not significantly different between the two groups, ejection fraction SMD = -0.10, 95% CI: -3.73, 3.52, left ventricular end-diastolic diameter SMD = -0.09, 95% CI: - 1.29, 1.11. Patients with TSH suppression after thyroid cancer had higher mean systolic blood pressure than controls (SMD = 1.97, 95% CI: -1.09, 5.03) and mean diastolic blood pressure (SMD = 1.85, 95% CI: -0.15, 3.85). Meta-analysis concluded that TSH suppression therapy after thyroid cancer surgery increases the risk of atrial fibrillation in patients. In addition, the heart rate, systolic blood pressure and diastolic blood pressure are higher than those in the control group, and there is no significant difference in ejection fraction and left ventricular end-diastolic diameter.
