Abstract Background South Africa has the largest population of human immunodeficiency virus (HIV) infected patients on antiretroviral therapy (ART) realising the benefits of increased life expectancy. However, this population may be susceptible to cardiovascular disease (CVD) development, due to the chronic consequences of a lifestyle-related combination of risk factors, HIV infection and ART. We predicted a 10-year cardiovascular mortality risk in an HIV-infected population on long-term ART, based on their observed metabolic risk factor profile. Methods We extracted data from hospital medical charts for 384 randomly selected HIV-infected patients aged ≥ 30 years. We defined metabolic syndrome (MetS) subcomponents using the International Diabetes Federation definition. A validated non-laboratory-based model for predicting a 10-year CVD mortality risk was applied and categorised into five levels, with the thresholds ranging from very low-risk (< 5%) to very high-risk scores (> 30%). Results Among the 384 patients, with a mean (± standard deviation) age of 42.90 ± 8.20 years, the proportion of patients that were overweight/obese was 53.3%, where 50.9% had low high-density lipoprotein (HDL) cholesterol and 21 (17.5%) had metabolic syndrome. A total of 144 patients with complete data allowed a definitive prediction of a 10-year CVD mortality risk. 52% (95% CI 44–60) of the patients were stratified to very low risk (< 5%) compared to 8% (95% CI 4–13) that were at a very high risk (> 30%) of 10-year CVD mortality. The CVD risk grows with increasing age (years), 57.82 ± 6.27 among very high risk and 37.52 ± 4.50; p < 0.001 in very low risk patients. Adjusting for age and analysing CVD risk mortality as a continuous risk score, increasing duration of HIV infection (p = 0.002) and ART (p = 0.007) were significantly associated with increased predicted 10 year CVD mortality risk. However, there was no association between these factors and categorised CVD mortality risk as per recommended scoring thresholds. Conclusions Approximately 1 in 10 HIV-infected patients is at very high risk of predicted 10-year CVD mortality in our study population. Like uninfected individuals, our study found increased age as a major predictor of 10-year mortality risk and high prevalence of metabolic syndrome. Additional CVD mortality risk due to the duration of HIV infection and ART was seen in our population, further studies in larger and more representative study samples are encouraged. It recommends an urgent need for early planning, prevention and management of metabolic risk factors in HIV populations, at the point of ART initiation.

Introduction: The most important way to reduce CVD-related mortality is to apply appropriate treatment according to the risk status of the patients. For this purpose, the SCORE risk model is used in Europe. In addition to these risk models, some anthropometric measurements are known to be associated with CVD risk and risk factors. Objectives: This study aimed to investigate the association of these anthropometric measurements, especially neck circumference (NC), with the SCORE risk chart. Methods: This was planned as a cross-sectional study. The study population were classified according to their SCORE risk values. The relationship of NC and other anthropometric measurements with the total cardiovascular risk indicated by the SCORE risk was investigated. Results: A total of 232 patients were included in the study. The patients participating in the study were analysed in four groups according to the SCORE ten-year total cardiovascular mortality risk. As a result, the NC was statistically significantly lower among the SCORE low and moderate risk group than all other SCORE risk groups (low-high and very high 36(3)–38(4) (IQR) p: 0.026, 36(3)–39(4) (IQR) p < 0.001, 36(3)–40(4) (IQR) p < 0.001), (moderate-high and very high 38(4) vs. 39(4) (IQR) p: 0.02, 38(4) vs. 40(4) (IQR) p < 0.001, 39(4) vs. 40(4) (IQR) p > 0.05). NC was found to have the strongest correlation with SCORE than the other anthropometric measurements. Conclusions: Neck circumference correlates strongly with the SCORE risk model which shows the ten-year cardiovascular mortality risk and can be used in clinical practice to predict CVD risk.

Abstract Background Infective endocarditis (IE) is diagnosed in 7–8% of streptococcal bloodstream infections (BSIs), yet it is unclear when to perform transthoracic (TTE) and transoesophageal echocardiography (TOE) according to different streptococcal species. The aim of this sub-study was to propose a flowchart for the use of echocardiography in streptococcal BSIs. Methods In a population-based setup, we investigated all patients admitted with streptococcal BSIs and crosslinked data with nationwide registries to identify comorbidities and concomitant hospitalization with IE. Streptococcal species were divided in four groups based on the crude risk of being diagnosed with IE (low-risk < 3%, moderate-risk 3–10%, high-risk 10–30% and very high-risk > 30%). Based on number of positive blood culture (BC) bottles and IE risk factors (prosthetic valve, previous IE, native valve disease, and cardiac device), we further stratified cases according to probability of concomitant IE diagnosis to create a flowchart suggesting TTE plus TOE (IE > 10%), TTE (IE 3–10%), or “wait & see” (IE < 3%). Results We included 6393 cases with streptococcal BSIs (mean age 68.1 years [SD 16.2], 52.8% men). BSIs with low-risk streptococci (S. pneumoniae, S. pyogenes, S. intermedius) are not initially recommended echocardiography, unless they have ≥3 positive BC bottles and an IE risk factor. Moderate-risk streptococci (S. agalactiae, S. anginosus, S. constellatus, S. dysgalactiae, S. salivarius, S. thermophilus) are guided to “wait & see” strategy if they neither have a risk factor nor ≥3 positive BC bottles, while a TTE is recommended if they have either ≥3 positive BC bottles or a risk factor. Further, a TTE and TOE are recommended if they present with both. High-risk streptococci (S. mitis/oralis, S. parasanguinis, G. adiacens) are directed to a TTE if they neither have a risk factor nor ≥3 positive BC bottles, but to TTE and TOE if they have either ≥3 positive BC bottles or a risk factor. Very high-risk streptococci (S. gordonii, S. gallolyticus, S. mutans, S. sanguinis) are guided directly to TTE and TOE due to a high baseline IE prevalence. Conclusion In addition to the clinical picture, this flowchart based on streptococcal species, number of positive blood culture bottles, and risk factors, can help guide the use of echocardiography in streptococcal bloodstream infections. Since echocardiography results are not available the findings should be confirmed prospectively with the use of systematic echocardiography.

Background: Metabolomics has provided new insights into mechanistic knowledge of CVD. However, this approach has limited use for studying arterial disease in high-risk women with and without HIV infection. Methods: Using liquid chromatography-tandem mass spectrometry, we profiled plasma levels of 114 cationic polar and 211 nonpolar lipid metabolites among 411 women (72% HIV+; 60% Black and 31% Hispanic) aged 35-50 from the Women’s Interagency HIV Study. Carotid arterial distensibility, a direct measure of carotid stiffness, was calculated from ultrasound measurements of the right common carotid artery diameter at systole and diastole and brachial artery pulse pressure measured. We performed partial least squares discriminant analysis (PLS-DA) to identify metabolite clusters associated with carotid stiffness (lowest vs. the other 3 quartiles of distensibility index). We used multivariate linear regression models to examine associations of individual metabolites with the distensibility index. Results: PLS-DA identified two major metabolite clusters associated with carotid stiffness. In the lipid metabolite cluster, triacylglycerols (TAGs 52:3, 52:4, 54:4), diacylglycerols (DAGs 36:2, 36:3) and sphingomyelins (16:1, 18:1, 18:2) were associated with decreased distensibility, while lysophosphatidylcholines (18:2, 20:5) were associated with increased distensibility. In the cationic polar metabolite cluster, urate, C4-OH carnitine, C5-DC carnitine, pseudouridine and 1-methyladenosine were associated with decreased distensibility. The associations of TAGs 52:3, 52:4, 54:4 and DAG 36:3 with carotid stiffness remained significant after further adjustment for conventional CVD risk factors ( Table ). No interaction by HIV infection was found. Conclusions: Among women with or at risk of HIV infection from predominantly race-ethnic minority groups, plasma TAGs and DAG of higher carbon number and double bond content are associated with carotid stiffness independent of conventional CVD risk factors.

Background: Coronary vascular disease (CVD) risk estimation tools are a simple means of identifying those at high risk in a community and hence a potentially cost-effective strategy for CVD prevention in resource-poor countries. The WHO /ISH risk prediction charts provide approximate estimates of cardiovascular disease risk in people who do not have established coronary heart disease, stroke or other atherosclerotic disease.Methods: A total of 280 subjects between 40 to 70 years of age were included in this cross sectional study. Eligible households was selected randomly (every 5th household) for the interview using systematic random sampling. Age, gender, smoking status, systolic blood pressure, presence or absence of diabetes and total serum cholesterol were used to compute the total CVD risk using WHO/ISH CVD risk prediction chart. The chart stratify an individual into low (<10%), moderate (10% to <20%), high (20% to <30%), and very high (>30%) risk groups.Results: Moderate and high CVD risk were 12.14% and 7.5% respectively. Of total study participants, 2.5% had very high risk (>40%). High risk (binge drinking) alcohol drinkers (p=0.04) and abdominal obesity (p=0.0001) were significantly associated with higher CVD risk. Higher prevalence of behavioral risk factors was also reported in our study population.Conclusions: A large proportion of the population is at moderate and high cardiovascular risk. Risk stratification and identification of individuals with a high risk for CHD who could potentially benefit from intensive primary prevention efforts are critically important in reducing the burden of CVD in India.

Background: Metabolic syndrome is a group of metabolic abnormalities in which the chance of developing cardiovascular disease, diabetes mellitus, chronic kidney disease are high. Aim: It aims at studying the lipid abnormalities in metabolic syndrome patients. Methods: Total of 100 metabolic syndrome patients were selected for study over a period of 1year. These patients were selected based on the criteria for metabolic syndrome as established by National Cholesterol Education Program (NCEP) adult Treatment Panel III (ATP III). Demographic data were taken and biochemical parameters were estimated by standard guideline. Results: Total cholesterol is significantly higher in very high risk (272.1 ± 8.591) compared to high risk (241.2 ± 3.901) and moderate risk (231.5 ± 4.498). TGL is significantly higher in very high risk (263.9 ± 13.70) compared to high risk (202.1 ± 6.531) and moderate risk (183.7 ± 7.650). HDL is almost same in very high risk (43.09 ± 1.533), high risk (40.44 ± 0.996) and moderate risk (42.53 ± 1.088). LDL is significantly higher in very high risk (177.9 ± 4.255) and high risk (169.4 ± 3.190) compared to moderate risk (155.7 ± 3.098). VLDL is significantly higher in very high risk (52.78 ± 2.739) compared to high risk (40.43 ± 1.306) and moderate risk (36.73 ± 1.530). CHO: HDL is significantly higher in very high risk (6.648 ± 0.366) compared to moderate risk (5.560 ± 0.207). High risk (6.060 ± 0.156) is not significantly different from very high risk and moderate risk. Thus, TC, TGL, LDL, VLDL, and CHO: HDL is significant as p value < 0.05 while HDL did not have any significance as p value > 0.05. Conclusion: In this study, high prevalence of dyslipidaemia is seen. So, timely diagnosis and treatment will help in detecting dyslipidaemia patients in future.

<b>Objectives: </b>To evaluate temporal prevalence trend, cardiometabolic risk factors, and the risk of atherosclerotic cardiovascular disease (ASCVD) and all-cause mortality (ACM) in incident young- and usual-onset type 2 diabetes. <p><b>Research Design and Methods: </b>From the UK primary care database, 370,854 people with new diagnosis of type 2 diabetes from 2000 to 2017 were identified. Analyses were conducted by age groups (18-39, 40-49, 50-59, 60-69, 70-79 years) and high/low risk status without history of ASCVD at diagnosis - ≥ two of current smoking, high SBP, high LDL-C or chronic kidney disease were classified as high-risk. </p> <p><b>Results:</b> Proportion of people aged <50 years at diagnosis increased during 2000-2010 and then stabilised. The incidence rates of ASCVD and ACM declined in people aged ≥50 years, but did not decrease in people <50 years. Compared to people aged ≥50 years, those aged 18-39 years at diagnosis had higher obesity (71% obese), higher HbA1c (8.6%), 71% had high LDL-C, while only 18% were on cardio-protective therapy. Although 2% in this age group had ASCVD at diagnosis, 23% were identified as high-risk. In the 18-39 years group, the adjusted average years to ASCVD /ACM in high-risk individuals (years (95% CI): 9.1 (8.2–10.0) /9.3 (8.1–10.4)) were similar to those with low-risk (years (95% CI): 10.0 (9.5 – 10.5) /10.5 (9.7–11.2)). However, individuals ≥50 years with high-risk were likely to experience an ASCVD event 1.5 - 2 years earlier and death 1.1 – 1.5 years earlier compared to low-risk groups (p<0.01). </p> <p><b>Conclusions: </b>Unlike usual-onset,<b> </b>young-onset type 2 diabetes have similar cardiovascular and mortality risk irrespective of their cardiometabolic risk factor status at diagnosis. The guidelines on the management of young-onset type 2 diabetes for intensive risk-factor management and cardioprotective therapies need to be urgently re-evaluated through prospective studies.<b> </b></p>

Abstract Background Haemolytic Uraemic Syndrome (HUS) is a serious complication of Shiga toxin-producing Escherichia coli (STEC) infection and the key reason why intensive health protection against STEC is required. However, although many potential risk factors have been identified, accurate estimation of risk of HUS from STEC remains challenging. Therefore, we aimed to develop a practical composite score to promptly estimate the risk of developing HUS from STEC. Methods This was a retrospective cohort study where data for all confirmed STEC infections in Ireland during 2013–15 were subjected to statistical analysis with respect to predicting HUS. Multivariable logistic regression was used to develop a composite risk score, segregating risk of HUS into ‘very low risk’ (0–0.4%), ‘low risk’ (0.5–0.9%), ‘medium risk’ (1.0–4.4%), ‘high risk’ (4.5–9.9%) and ‘very high risk’ (10.0% and over). Results There were 1397 STEC notifications with complete information regarding HUS, of whom 5.1% developed HUS. Young age, vomiting, bloody diarrhoea, Shiga toxin 2, infection during April to November, and infection in Eastern and North-Eastern regions of Ireland, were all statistically significant independent predictors of HUS. Demonstration of a risk gradient provided internal validity to the risk score: 0.2% in the cohort with ‘very low risk’ (1/430), 1.1% with ‘low risk’ (2/182), 2.3% with ‘medium risk’ (8/345), 3.1% with ‘high risk’ (3/98) and 22.2% with ‘very high risk’ (43/194) scores, respectively, developed HUS. Conclusion We have developed a composite risk score which may be of practical value, once externally validated, in prompt estimation of risk of HUS from STEC infection.

Abstract Background Turkey is among the top countries in Europe in coronary mortality in the 45-74 age range. The highest death due to disorders of the circulatory system (50.8%) that is Amasya province. Objective Determine related factors and to compare with actual and perceived cardiovascular disease (CVD) risks of men aged 40-65 living in Amasya. Methods The sample size of cross-sectional and analytical study consisted of 400 people who met the inclusion criteria. Actual CVD risks of men were calculated using HeartScore. Age, systolic blood pressure, total cholesterol measured by blood taken from the capillary and smoking status were used to calculate CVD risk. Actual CVD risk in next decade has been calculated as low, medium, high or very high. Perceived CVD risk in next decade were identified by participants as low, medium, high and very high responses. They also questioned why evaluation of perceived risk. Results It was determined whereas 8.3% of the males had high, 52.5% had a very high level of CVD risk. The main variables affecting actual CVD risk; diastolic blood pressure, BMI and physical activity. 13.3% of males perceived CVD risks at high and 8% at very high. The main variables affecting perceived CVD risk; age and DM. It was found that 48% and 23.8% of males perceived CVD risks lower and higher than actual CVD risk while 28.2% were accurate. Those who perceived CVD risk at a moderate, high and very high think that this is caused by diseases that increase the risk of CVD and smoking. Conclusions Approximately 1/2 men has very high risk of CVD. It was determined that 1/2 men perceived risks are lower with false optimism and couldn’t accurately identify risks of people older and with diabetes. Key messages It can be ensured that develop risk reducing behaviors and individuals with high risk of CVD can raise their awareness. The risk perceptions of males in the very high-risk group from the past to the present are important because they affect their actual risks and risk-reducing behaviors.

ABSTRACT Innate immune factors in mucosal secretions may influence human immunodeficiency virus type 1 (HIV-1) transmission. This study examined the levels of three such factors, genital tract lactoferrin [Lf], secretory leukocyte protease inhibitor [SLPI], and RANTES, in women at risk for acquiring HIV infection, as well as cofactors that may be associated with their presence. Women at high risk for HIV infection meeting established criteria (n = 62) and low-risk controls (n = 33) underwent cervicovaginal lavage (CVL), and the CVL fluid samples were assayed for Lf and SLPI. Subsets of 26 and 10 samples, respectively, were assayed for RANTES. Coexisting sexually transmitted infections and vaginoses were also assessed, and detailed behavioral information was collected. Lf levels were higher in high-risk (mean, 204 ng/ml) versus low-risk (mean, 160 ng/ml, P = 0.007) women, but SLPI levels did not differ, and RANTES levels were higher in only the highest-risk subset. Lf was positively associated only with the presence of leukocytes in the CVL fluid (P < 0.0001). SLPI levels were lower in women with bacterial vaginosis [BV] than in those without BV (P = 0.04). Treatment of BV reduced RANTES levels (P = 0.05). The influence, if any, of these three cofactors on HIV transmission in women cannot be determined from this study. The higher Lf concentrations observed in high-risk women were strongly associated with the presence of leukocytes, suggesting a leukocyte source and consistent with greater genital tract inflammation in the high-risk group. Reduced SLPI levels during BV infection are consistent with an increased risk of HIV infection, which has been associated with BV. However, the increased RANTES levels in a higher-risk subset of high-risk women were reduced after BV treatment.
