    It has been suggested that systolic time intervals (STI) can be used to monitor the cardiac effects of antihypertensive treatments and also to evaluate hypertensive patients. STI changes observed in hypertensives have been ascribed to myocardial disease, although they could be due to the existence of a relationship between STI and blood pressure. A group of 37 subjects (18 normotensives and 19 hypertensives) with no signs of heart failure and left ventricular dysfunction were studied to examine the relationship of STI to blood pressure. Pacing with an external battery pulse generator was performed at the rate of 95 beats/min in order to eliminate differences in heart rate. STI were measured from good quality high speed (100 mm/s) recordings and the average value of 10 consecutive cardiac cycles was used for statistical analysis. Normal subjects showed significantly lower values of pre-ejection period (PEP), electromechanical systole (QS2), and pre-ejection period/left ventricular ejection time ratio (PEP/LVET). Moreover, a significant inverse relationship between diastolic pressure and LVET and significant direct relationships between diastolic pressure and PEP, systolic pressure and PEP, diastolic pressure and PEP/LVET, and between systolic pressure and PEP/LVET were demonstrated. We suggest to consider the relation of STI to blood pressure to provide regression equations to best appreciate and use STI

    Does ergometric stress test induce a procoagulative condition in patients with previous myocardial infarction

    A regularly scheduled physical training program seems to have antithrombotic effects. Moreover, the hemostatic changes occurring in patients with coronary artery disease during acute exercise have not been clearly elucidated. Since stress testing is routinely performed in clinical cardiology, it would be helpful to assess whether patients with coronary artery disease are exposed to acute coronary thrombosis during or soon after sustained physical exercise. This study was designed to evaluate the effect of acute physical exercise (stress test by bicycle ergometer) on blood coagulation in a group of patients with previous myocardial infarction, and to determine whether the antithrombotic therapy commonly administered favorably influences hemostatic equilibrium. Our results suggest that exercise testing is not harmful to patients with previous myocardial infarction in regard to hemostasis and fibrinolysis and that antithrombotic therapy reduces postexercise increase in platelets

    Trends in Net Survival from Vulvar Squamous Cell Carcinoma in Italy (1990–2015)

    Objective: In many Western countries, survival from vulvar squamous cell carcinoma (VSCC) has been stagnating for decades or has increased insufficiently from a clinical perspective. In Italy, previous studies on cancer survival have not taken vulvar cancer into consideration or have pooled patients with vulvar and vaginal cancer. To bridge this knowledge gap, we report the trend in survival from vulvar cancer between 1990 and 2015. (2) Methods: Thirty-eight local cancer registries covering 49% of the national female population contributed the records of 6274 patients. Study endpoints included 1- and 2-year net survival (NS) calculated using the Pohar-Perme estimator and 5-year NS conditional on having survived two years (5|2-year CNS). The significance of survival trends was assessed with the Wald test on the coefficient of the period of diagnosis, entered as a continuous regressor in a Poisson regression model. (3) Results: The median patient age was stable at 76 years. One-year NS decreased from 83.9% in 1990–2001 to 81.9% in 2009–2015 and 2-year NS from 72.2% to 70.5%. Five|2-year CNS increased from 85.7% to 86.7%. These trends were not significant. In the age stratum 70–79 years, a weakly significant decrease in 2-year NS from 71.4% to 65.7% occurred. Multivariate analysis adjusting for age group at diagnosis and geographic area showed an excess risk of death at 5|2-years, of borderline significance, in 2003–2015 versus 1990–2002. (4) Conclusions: One- and 2-year NS and 5|2-year CNS showed no improvements. Current strategies for VSCC control need to be revised both in Italy and at the global level

    Improvement of medication adherence in adolescents and young adults with SLE using web-based education with and without a social media intervention, a pilot study

    Abstract Background Self-management skills, including medication management, are vital to the health of adolescents and young adults with systemic lupus erythematosus (SLE). The purpose of this study was to assess the feasibility and preliminary effects of an online educational program in a cohort of adolescent and young adults with SLE with and without a social media (SM) experience. Methods Adolescents and young adults with SLE participated weekly for 8 sessions on a web-based educational program about SLE created specifically for this project. Subjects were randomized to respond to questions at the end of each weekly module in a journal or on a SM forum with other SLE subjects. Patients were surveyed prior to initiating the study, (T0) and 6 weeks after completion of the sessions (T1). Medication adherence for hydroxychloroquine, utilizing the medication possession ratio (MPR), was compared for the 3 months preceding T0 and for the 3 months following T1. Results Twenty-seven of the 37 subjects (73%) enrolled completed the study, including the two required sets of surveys. Reasons for being lost to follow up included being too busy, forgetting, and/or not seeing email reminders. Medication adherence improved in all subjects (p < 0.001). The percentage of the SM intervention group that was adherent (MPR ≥ 80%) significantly improved from 50% to 92% (p = 0.03), while the control group did not. Secondary outcome measures that improved, only in the SM group, included self-efficacy, sense of agency (SOA), sense of community (SOC), and empowerment. There was a strong correlation between empowerment with SOA and SOC and in turn a strong correlation with SOA and SOC with MPR, providing a possible explanation for why social media participation helped to improve medication adherence. Subjective reporting of medication adherence was not reliably correlated to MPR. Conclusions This pilot study has demonstrated feasibility for the use of an online educational SLE website, recruitment, and measurement of chosen outcome measures. This study provides evidence for a larger multi-site trial which has the potential to address an important service gap by delivering self-management education and peer interactions in a format that is accessible, and engaging to young people with SLE.
