Metabolic Syndrome and Heart Transplantation: An Underestimated Risk Factor?

Metabolic Syndrome (MetS), a multifactorial condition that increases the risk of cardio-vascular events, is frequent in Heart-transplant (HTx) candidates and worsens with immunosuppressive therapy. The aim of the study was to analyze the impact of MetS on long-term outcome of HTx patients. Since 2007, 349 HTx patients were enrolled. MetS was diagnosed if patients met revised NCEP-ATP III criteria before HTx, at 1, 5 and 10 years of follow-up. MetS was present in 35% of patients pre-HTx and 47% at 1 year follow-up. Five-year survival in patients with both pre-HTx (65% vs. 78%, p < 0.01) and 1 year follow-up MetS (78% vs 89%, p < 0.01) was worst. At the univariate analysis, risk factors for mortality were pre-HTx MetS (HR 1.86, p < 0.01), hypertension (HR 2.46, p < 0.01), hypertriglyceridemia (HR 1.50, p=0.03), chronic renal failure (HR 2.95, p < 0.01), MetS and diabetes at 1 year follow-up (HR 2.00, p < 0.01; HR 2.02, p < 0.01, respectively). MetS at 1 year follow-up determined a higher risk to develop Coronary allograft vasculopathy at 5 and 10 year follow-up (25% vs 14% and 44% vs 25%, p < 0.01). MetS is an important risk factor for both mortality and morbidity post-HTx, suggesting the need for a strict monitoring of metabolic disorders with a careful nutritional follow-up in HTx patients.

Breast cancer deaths attributable to alcohol consumption: Italy, 2015-2019.

A study was conducted to assess the fraction of female breast cancer (BC) deaths attributable to alcohol consumption in Italy. National mortality data for the period 2015-2019 were used along with national estimates of women from the general population exposed to moderate (11-20 gr/day) or heavy (>20 gr/day) alcohol consumption. From 2015 to 2019, 2918 (4.6%) out of 63,428 BC| deaths were attributable to alcohol consumption, including 1269 deaths (2.0%) caused by moderate consumption. Study findings could help stakeholders to prioritize programs aimed at reducing alcohol consumption, and to improve ways to effectively communicate alcohol-related health risks, including moderate consumption.

A Web Tool to Help Counter the Spread of Misinformation and Fake News: Pre-Post Study Among Medical Students to Increase Digital Health Literacy.

BACKGROUND: The COVID-19 pandemic was accompanied by the spread of uncontrolled health information and fake news, which also quickly became an infodemic. Emergency communication is a challenge for public health institutions to engage the public during disease outbreaks. Health professionals need a high level of digital health literacy (DHL) to cope with difficulties; therefore, efforts should be made to address this issue starting from undergraduate medical students. OBJECTIVE: The aim of this study was to investigate the DHL skills of Italian medical students and the effectiveness of an informatics course offered by the University of Florence (Italy). This course focuses on assessing the quality of medical information using the "dottoremaeveroche" (DMEVC) web resource offered by the Italian National Federation of Orders of Surgeons and Dentists, and on health information management. METHODS: A pre-post study was conducted at the University of Florence between November and December 2020. First-year medical students participated in a web-based survey before and after attending the informatics course. The DHL level was self-assessed using the eHealth Literacy Scale for Italy (IT-eHEALS) tool and questions about the features and quality of the resources. All responses were rated on a 5-point Likert scale. Change in the perception of skills was assessed using the Wilcoxon test. RESULTS: A total of 341 students participated in the survey at the beginning of the informatics course (women: n=211, 61.9%; mean age 19.8, SD 2.0) and 217 of them (64.2%) completed the survey at the end of the course. At the first assessment, the DHL level was moderate, with a mean total score of the IT-eHEALS of 2.9 (SD 0.9). Students felt confident about finding health-related information on the internet (mean score of 3.4, SD 1.1), whereas they doubted the usefulness of the information they received (mean score of 2.0, SD 1.0). All scores improved significantly in the second assessment. The overall mean score of the IT-eHEALS significantly increased (P<.001) to 4.2 (SD 0.6). The item with the highest score related to recognizing the quality of health information (mean score of 4.5, SD 0.7), whereas confidence in the practical application of the information received remained the lowest (mean of 3.7, SD 1.1) despite improvement. Almost all students (94.5%) valued the DMEVC as an educational tool. CONCLUSIONS: The DMEVC tool was effective in improving medical students' DHL skills. Effective tools and resources such as the DMEVC website should be used in public health communication to facilitate access to validated evidence and understanding of health recommendations.

Red blood distribution width and heart transplantation: any predictive role on patient outcome?

BACKGROUND: Red blood cell distribution width (RDW) has been emerging as a strong predictor of mortality among patients with cardiovascular disease. The aim of this study was to verify if RDW is able to predict survival after heart transplantation (HTx). METHODS: Two hundred and eighteen recipients who underwent HTx between 2000 and 2013 were classified into three groups according to the pre-HTx RDW tertile values (14.6 and 16.4%), and their outcomes were compared. Mean follow-up was 6.6 ±â€Š4.2 years. RESULTS: RDW correlated with other markers of chronic pathological conditions, such as the Index for Mortality Prediction after Cardiac Transplantation (IMPACT) score (P = 0.002) and Charlson Comorbidity Index (P < 0.001), and with creatinine levels (P = 0.007), previous cardiac surgery (P < 0.001), diabetes mellitus (P = 0.02), haemoglobin value (P = 0.004), pulmonary capillary wedge and central venous pressures (P = 0.019 and 0.01, respectively), systolic and mean pulmonary artery pressures (P = 0.002 and 0.014, respectively). The rate of 30-day mortality from the lowest to the highest RDW tertile was 1.4, 4 and 9% (P = 0.02), respectively.Long-term mortality correlated at multivariate analysis with recipient age [hazard ratio 1.06, 95% confidence interval (95% CI) 1.02-1.09], donor age (hazard ratio 1.02, 95% CI 1.0-1.04) and RDW (hazard ratio 1.13, 95% CI 1.04-1.23). The survival probability at 4, 8 and 12 years was 90, 84 and 74% for recipients with RDW less than 14.6%, while it was 72, 60 and 42% for recipients with RDW more than 16.4% (hazard ratio 3.29, 95% CI 1.74-6.24). No differences were found between causes of death. CONCLUSION: RDW correlated with survival in HTx recipients. This marker of blood cell size may represent a surrogate of disease and a helpful tool in the risk-assessment process.
