Testosterone-to-estradiol ratio and platelet thromboxane release in ischemic heart disease: the EVA project

Background Data on the interplay between sexual hormones balance, platelet function and clinical outcomes of adults with ischemic heart disease (IHD) are still lacking. Objective To assess the association between the Testosterone (T)-to-Estradiol (E2) Ratio (T/E2) and platelet activation biomarkers in IHD and its predictive value on adverse outcomes. Methods The EVA study is a prospective observational study of consecutive hospitalized adults with IHD undergoing coronary angiography and/or percutaneous coronary interventions. Serum T/E2 ratios E2, levels of thromboxane B-2 (TxB(2)) and nitrates (NO), were measured at admission and major adverse events, including all-cause mortality, were collected during a long-term follow-up. Results Among 509 adults with IHD (mean age 67 +/- 11 years, 30% females), males were older with a more adverse cluster of cardiovascular risk factors than females. Acute coronary syndrome and non-obstructive coronary artery disease were more prevalent in females versus males. The lower sex-specific T/E2 ratios identified adults with the highest level of serum TxB(2) and the lowest NO levels. During a median follow-up of 23.7 months, the lower sex-specific T/E2 was associated with higher all-cause mortality (HR 3.49; 95% CI 1.24-9.80; p = 0.018). In in vitro, platelets incubated with T/E2 ratios comparable to those measured in vivo in the lowest quartile showed increased platelet activation as indicated by higher levels of aggregation and TxB(2) production. Conclusion Among adults with IHD, higher T/E2 ratio was associated with a lower long-term risk of fatal events. The effect of sex hormones on the platelet thromboxane release may partially explain such finding

A machine-learning based bio-psycho-social model for the prediction of non-obstructive and obstructive coronary artery disease

Background: Mechanisms of myocardial ischemia in obstructive and non-obstructive coronary artery disease (CAD), and the interplay between clinical, functional, biological and psycho-social features, are still far to be fully elucidated. Objectives: To develop a machine-learning (ML) model for the supervised prediction of obstructive versus non-obstructive CAD. Methods: From the EVA study, we analysed adults hospitalized for IHD undergoing conventional coronary angiography (CCA). Non-obstructive CAD was defined by a stenosis < 50% in one or more vessels. Baseline clinical and psycho-socio-cultural characteristics were used for computing a Rockwood and Mitnitski frailty index, and a gender score according to GENESIS-PRAXY methodology. Serum concentration of inflammatory cytokines was measured with a multiplex flow cytometry assay. Through an XGBoost classifier combined with an explainable artificial intelligence tool (SHAP), we identified the most influential features in discriminating obstructive versus non-obstructive CAD. Results: Among the overall EVA cohort (n = 509), 311 individuals (mean age 67 ± 11 years, 38% females; 67% obstructive CAD) with complete data were analysed. The ML-based model (83% accuracy and 87% precision) showed that while obstructive CAD was associated with higher frailty index, older age and a cytokine signature characterized by IL-1β, IL-12p70 and IL-33, non-obstructive CAD was associated with a higher gender score (i.e., social characteristics traditionally ascribed to women) and with a cytokine signature characterized by IL-18, IL-8, IL-23. Conclusions: Integrating clinical, biological, and psycho-social features, we have optimized a sex- and gender-unbiased model that discriminates obstructive and non-obstructive CAD. Further mechanistic studies will shed light on the biological plausibility of these associations. Clinical trial registration: NCT02737982

The Sex-Specific Detrimental Effect of Diabetes and Gender-Related Factors on Pre-admission Medication Adherence Among Patients Hospitalized for Ischemic Heart Disease: Insights From EVA Study

Background: Sex and gender-related factors have been under-investigated as relevant determinants of health outcomes across non-communicable chronic diseases. Poor medication adherence results in adverse clinical outcomes and sex differences have been reported among patients at high cardiovascular risk, such as diabetics. The effect of diabetes and gender-related factors on medication adherence among women and men at high risk for ischemic heart disease (IHD) has not yet been fully investigated.Aim: To explore the role of sex, gender-related factors, and diabetes in pre-admission medication adherence among patients hospitalized for IHD.Materials and Methods: Data were obtained from the Endocrine Vascular disease Approach (EVA) (ClinicalTrials.gov Identifier: NCT02737982), a prospective cohort of patients admitted for IHD. We selected patients with baseline information regarding the presence of diabetes, cardiovascular risk factors, and gender-related variables (i.e., gender identity, gender role, gender relations, institutionalized gender). Our primary outcome was the proportion of pre-admission medication adherence defined through a self-reported questionnaire. We performed a sex-stratified analysis of clinical and gender-related factors associated with pre-admission medication adherence.Results: Two-hundred eighty patients admitted for IHD (35% women, mean age 70), were included. Around one-fourth of the patients were low-adherent to therapy before hospitalization, regardless of sex. Low-adherent patients were more likely diabetic (40%) and employed (40%). Sex-stratified analysis showed that low-adherent men were more likely to be employed (58 vs. 33%) and not primary earners (73 vs. 54%), with more masculine traits of personality, as compared with medium-high adherent men. Interestingly, women reporting medication low-adherence were similar for clinical and gender-related factors to those with medium-high adherence, except for diabetes (42 vs. 20%, p = 0.004). In a multivariate adjusted model only employed status was associated with poor medication adherence (OR 0.55, 95%CI 0.31–0.97). However, in the sex-stratified analysis, diabetes was independently associated with medication adherence only in women (OR 0.36; 95%CI 0.13–0.96), whereas a higher masculine BSRI was the only factor associated with medication adherence in men (OR 0.59, 95%CI 0.35–0.99).Conclusion: Pre-admission medication adherence is common in patients hospitalized for IHD, regardless of sex. However, patient-related factors such as diabetes, employment, and personality traits are associated with adherence in a sex-specific manner

Monkeypox Outbreak 2022: Clinical and Virological Features of 30 Patients at the Sexually Transmitted Diseases Centre of Sant' Orsola Hospital, Bologna, Northeastern Italy

Monkeypox infection is a zoonosis first described in humans in 1970 in Congo. While previously manifesting in small, confined outbreaks, the disease is rapidly spreading globally. The aim of this study was to investigate microbiological samples (skin, rectal, and oropharyngeal swab samples and plasma and urine samples) that can help in adequate diagnostic, therapeutic, and prognostic management. We present 30 laboratory-confirmed monkeypox patients with peculiar clinical and virological features admitted to the Sexually Transmitted Diseases Centre of Sant' Orsola Hospital, University of Bologna, in the period between 20 June and 10 August 2022. Demographic, anamnestic, and clinical data were obtained, and microbiological samples were collected and analyzed by real-time PCR to detect the presence of monkeypox virus (MPXV) DNA. All monkeypox patients were adult men who have sex with men (MSM) (mean age, 37.5 years). Nonskin samples were collected from 29 patients during the acute phase of the infection. The detection rates of MPXV DNA in plasma, urine, and oropharyngeal swab samples (82.3%, 64.7%, and 75.0%, respectively) were highest in samples collected 4 to 6 days after symptom onset. The presence of MPXV in plasma and urine samples was analyzed 11 to 38 days after symptom onset to monitor viral shedding duration. Interestingly, MPXV DNA was detected in a urine sample collected on day 21 in one patient. Prolonged positivity in urine after the clinical recovery suggests a potential source of infection by contamination of wastewater and sewage and transmission to possible animal reservoirs and highlights the need for further investigations on nonskin samples to extend and more adequately standardize the patient isolation period.Monkeypox infection is a zoonosis first described in humans in 1970 in Congo.

High focused Evaluation of Atherosclerotic risk profile in Retinal Thrombosis: Vascular events Incidence, Sex involvement and Interventional outcomes assessed by Ophthalmologists and internists Network – HEART VISION study protocol

Background and objectives: Retinal vein occlusion (RVO), one of the most relevant causes of vision loss, still represents an open issue in ophthalmology and vascular medicine. Its epidemiology and management approach have not been clearly characterized yet, with several grey zones requiring investigation. Significance of RVO on cardiovascular prognosis is also unclear. “High focused Evaluation of Atherosclerotic risk profile in Retinal Thrombosis: Vascular events Incidence, Sex involvement and Interventional outcomes assessed by Ophthalmologists and internists Network” (HEART VISION) is a longitudinal, prospective, multi-center study which aims at determining the epidemiology, potentially modifiable risk factors and the determinants of RVO in an Italian-based cohort. Methods: Enrollment of all the eligible patients presenting to recruiting centers (i.e. ophthalmology emergency room and thrombosis centers) with suspect of RVO. At baseline, all patients will undergo an opthalmologic evaluation and further investigations about cardiovascular co-morbidities and risk factors. Recruited patients will be followed for a 2-year period. Outcome measures: Data about adverse cardiovascular events and eye-related outcomes will be recorded. Discussion: HEART VISION will present data on prevalence and will inform on the prognosis of RVO in an Italian-based cohort. Characterization and prospective evaluation of these patients will be useful in developing novel strategies for management of RVO and their cardiovascular-related risk factors. Ethics and dissemination: This study protocol (n. 1.0, 01.07.2014) was approved by the Sapienza-University of Rome, Ethics Board (Protocol No. 1076/14). This study will be performed in accordance with the Declaration of Helsinki. Dissemination plans include presentations at scientific conferences and publication in scientific journals.

Anti-Obesity and Anti-Inflammatory Effects of Novel Carvacrol Derivatives on 3T3-L1 and WJ-MSCs Cells

(1) Background: Obesity, a complex metabolic disease resulting from an imbalance between food consumption and energy expenditure, leads to an increase in adipocytes and chronic inflammatory conditions. The aim of this paper was to synthesize a small series of carvacrol derivatives (CD1-3) that are able to reduce both adipogenesis and the inflammatory status often associated with the progression of the obesity disease. (2) Methods: The synthesis of CD1-3 was performed using classical procedures in a solution phase. Biological studies were performed on three cell lines: 3T3-L1, WJ-MSCs, and THP-1. The anti-adipogenic properties of CD1-3 were evaluated using western blotting and densitometric analysis by assessing the expression of obesity-related proteins, such as ChREBP. The anti-inflammatory effect was estimated by measuring the reduction in TNF-α expression in CD1-3-treated THP-1 cells. (3) Results: CD1-3—obtained through a direct linkage between the carboxylic moiety of anti-inflammatory drugs (Ibuprofen, Flurbiprofen, and Naproxen) and the hydroxyl group of carvacrol—have an inhibitory effect on the accumulation of lipids in both 3T3-L1 and WJ-MSCs cell cultures and an anti-inflammatory effect by reducing TNF- α levels in THP-1 cells. (4) Conclusions: Considering the physicochemical properties, stability, and biological data, the CD3 derivative—obtained by a direct linkage between carvacrol and naproxen—resulted in the best candidate, displaying anti-obesity and anti-inflammatory effects in vitro.</jats:p
