Abstract Funding Acknowledgements Type of funding sources: Private grant(s) and/or Sponsorship. Main funding source(s): Medilab SARL Backgroung Given the expected epidemic rise of coronary heart disease (CHD) in healthcare system and the potential severity of disease, CHD remains underestimated in women. Early identification of risk factors (RFs) will be important for their health promotion. Purpose The aim of this study is to evaluate the RFs for CHD among Lebanese women aged 40 years and above. Methods A case-control study was carried out in 6 hospitals in the regions of Beirut and Mount-Lebanon, from December 2018 to December 2019 with a total of 1500 patients. Anthropometric and laboratory data were collected from the medical records of patients and structured questionnaire were used. Results CHD was positively associated with hyperlipidemia (aOR 2.852, 95% CI: 2.021–4.023), hypertension (2.715, 1.598–4.614), family history of CHD (2.645, 1.925–3.634), smoking (1.888, 1.393–2.558) and interestingly presence of joint pain (1.513, 1.107–2.068). While, residence in Mount-Lebanon seemed negatively associated with CHD (0.669, 0.467–0.959), as well as adherence to Mediterranean diet (0.964, 0.938–0.992) and physical activity (0.491, 0.259–0.930 and 0.718, 0.530–0.972, for high and moderate activity, respectively). Conclusion In our study, most of RFs associated with CHD in women are modifiable and preventable, highlighting the need of lifestyle interventions and appropriate control strategies and measures.

Background HIV-positive patients have an estimated twofold increased risk of acute myocardial infarction and coronary heart disease (CHD). While traditional cardiovascular risk factors and the effects of HIV and chronic inflammation all play a role, the contribution of long-term exposure to antiretroviral (ARV) agents is becoming clear. Methods: We performed a retrospective case–control study of HIV-positive patients seen from January 1996 to December 2009 to evaluate the impact of HIV suppression and exposure to specific ARVs on the incidence of CHD. Results: Cases (n = 68) were HIV-positive with evidence of CHD. Two age- and sex-matched HIV-positive controls (n = 136) without a diagnosis of CHD were assigned for each case. The cumulative incidence of CHD in the period covered by the study was 3.8%, with an incidence of 8.5 cases per 1000 patient-years of follow up. Cases had an increased likelihood of having hypertension (odds ratio (OR): 6.62, P < 0.001), a family history of CHD (OR: 5.82, P < 0.001), lower high-density lipoprotein levels (OR: 0.28, P = 0.025) and higher Framingham risk scores compared with controls. Following adjustment for traditional cardiovascular risk factors, the presence of CHD was significantly associated with the current use of abacavir (OR: 2.10, P = 0.03). Protease inhibitor therapy, HIV viral load and duration of known HIV infection were not predictive of CHD in our patient population. Conclusions: Our data add to the evidence that abacavir use is associated with CHD in HIV-positive patients in Australia.

IntroductionDementia is a group of disabling disorders that can be devastating for persons living with it and for their families. Data-informed decision-making strategies to identify individuals at high risk of dementia are essential to facilitate large-scale prevention and early intervention. This population-based case–control study aims to develop and validate a clinical algorithm for predicting dementia diagnosis, based on the cognitive footprint in personal and medical history.Methods and analysisWe will use territory-wide electronic health records from the Clinical Data Analysis and Reporting System (CDARS) in Hong Kong between 1 January 2001 and 31 December 2018. All individuals who were at least 65 years old by the end of 2018 will be identified from CDARS. A random sample of control individuals who did not receive any diagnosis of dementia will be matched with those who did receive such a diagnosis by age, gender and index date with 1:1 ratio. Exposure to potential protective/risk factors will be included in both conventional logistic regression and machine-learning models. Established risk factors of interest will include diabetes mellitus, midlife hypertension, midlife obesity, depression, head injuries and low education. Exploratory risk factors will include vascular disease, infectious disease and medication. The prediction accuracy of several state-of-the-art machine-learning algorithms will be compared.Ethics and disseminationThis study was approved by Institutional Review Board of The University of Hong Kong/Hospital Authority Hong Kong West Cluster (UW 18-225). Patients’ records are anonymised to protect privacy. Study results will be disseminated through peer-reviewed publications. Codes of the resulted dementia risk prediction algorithm will be made publicly available at the website of the Tools to Inform Policy: Chinese Communities’ Action in Response to Dementia project (https://www.tip-card.hku.hk/).

AbstractDuring the development of atherosclerotic lesion, s-RNYs (small RNAs of about 24/34 nucleotides) are derived by the processing of long Ro-associated non-coding RNAs (RNYs) in macrophages. The levels of serum s-RNYs have been found significantly upregulated in patients with coronary heart disease (CHD) compared to age-matched CHD-free individuals. The present study aimed to examine the predictive value of serum s-RNYs for CHD events in the general male population. Within the frame of nested-case–control study, the GENES study, we measured the absolute expression of a RNY-derived small RNA, the s-RNY1-5p, in the serum of individuals (without CHD at baseline) who encountered a CHD event within 12 years of follow-up (n = 30) (Cases) and compared them to individuals who remained event-free (Controls) (n = 30). The expression of s-RNY1-5p in serum was significantly upregulated in Cases compared to Controls (p = 0.027). The proportion of CHD event-free was significantly higher among individuals with serum s-RNY1-5p below the median value (631 molecules/mL). In a multivariable model adjusted for age, smoking, hypertension, diabetes and dyslipidemia, the risk of CHD events increased more than fourfold in individuals with serum s-RNY1-5p above the median value (HR, 4.36; 95% CI 1.22–15.60). A positive association with CHD events was also observed when considering s-RNY1-5p as a continuous variable (p = 0.022). Based on our results, we conclude that serum s-RNY1-5p is an independent predictor of CHD events in a general male population and might be a relevant biomarker for early detection of cardiovascular diseases.

BACKGROUND: Oxidative stress and chronic inflammation are among the leading causes of coronary heart disease (CHD). Studies investigated the relationship between dietary antioxidants and the risk/odds of CHD, and contradictory results have been reported. Dietary antioxidant index (DAI) is a novel and reliable nutritional tool that examines the diet’s overall antioxidant capacity. Its validity was examined using serum total antioxidant capacity and malondialdehyde. OBJECTIVE: This study aimed to investigate the relationship between DAI score and odds of CHD. METHODS: In this incidence case-control study, 320 individuals with a definitive diagnosis of CHD and 320 participants without CHD or related risk factors attending the same hospitals/polyclinics were selected as the case and control groups. We estimated the DAI by summing up six standardized intakes of major dietary antioxidants, including manganese, vitamin E, A, C, selenium, and zinc. RESULTS: Modeling DAI categorized according to the median (–0.38), in multi-adjusted model showed a significant protective association with the odd of CHD (OR = 0.72; 95%CI:0.51–0.99, p-value = 0.05). Also, modeling DAI as a continuous variable in multi-adjusted models (OR = 0.94;95%CI:0.90–0.95; p-value = 0.01) showed significant results. CONCLUSION: Using the DAI to investigate the relationship between dietary antioxidants and CHD can show more realistic results than a single study of antioxidants.
