Acute decompensated heart failure (ADHF) is one of the leading causes for hospitalization and mortality. Identifying high risk patients is essential to ensure proper management. Sequential Organ Function Assessment Score (SOFA) is considered an excellent score to predict short-term mortality in sepsis and other life-threatening conditions. To assess the capability of SOFA score in predicting short-term mortality in ADHF. We retrospectively identified patients with first hospitalization with primary diagnosis of ADHF between the years (2008–2018). The SOFA score was calculated for all patients. A total 3232 patients were included in the study. The SOFA score was significantly associated with in-hospital mortality and 30-day mortality. The odds ratios for 1-point increase in the SOFA score were 1.86 (95% CI 1.68–1.96) and 1.627 (95% CI 1.523–1.737) respectively. The SOFA Score demonstrated a good predictive accuracy. The areas under the curve of receiver operating characteristic curves for in-hospital mortality and 30-day mortality were 0.765 (95% CI 0.733–0.798) and 0.706 (95% CI 0.676–0.736) respectively. SOFA score is associated with increased risk of short-term mortality in ADHF. SOFA can be used as a complementary risk score to screen high risk patients who need strict monitoring.

Summary Although many case reports and observational studies have reported a correlation between iron deficiency anaemia (IDA) and thrombotic events, the mechanism for this is poorly understood. To evaluate this, we examined the change in coagulability in patients receiving treatment for IDA. Adult patients with IDA were recruited for this study and treated with intravenous iron. The change in coagulability was assessed by thrombin generation using the calibrated automated thrombogram method. The change in factor VIII (FVIII) activity was later examined as a possible link. Forty‐eight participants received intravenous iron and were included in this study. After treatment with intravenous iron, endogenous thrombin potential and peak height decreased in IDA patients by a mean of 122·4 nmol/l/min (95% confidence interval [CI]: 17·9–227, P = 0·023) and 51·9 (95% CI: 26·6–77·2, P < 0·001) respectively. Time to peak (peak time) increased by a mean of 23·6 s (95% CI: 5·4–41·9, P = 0·012). FVIII activity was reduced by a mean of 9·6% (95% CI: 2·54–16·7, P = 0·009). In conclusion, treating IDA reduces the blood's coagulability, as evidenced by the change in thrombin generation and FVIII activity levels. No correlation was found between the degree of iron deficiency correction and thrombogram parameters.

Background Although regulatory changes towards correcting the underrepresentation of women in randomized controlled trials (RCTs) occurred (National Institutes of Health 1994), concerns exist about whether an improvement is taking place. In this systematic review and meta-analysis, we aimed to assess the inclusion rates of women in recent RCTs and to explore the potential barriers for the enrollment of women. Methods RCTs published in 2017 examining any type of intervention in adults were searched in PubMed and Cochrane Library. The following predefined medical fields were included: cardiovascular diseases, neoplasms, endocrine system diseases, respiratory tract diseases, bacterial and fungal infections, viral diseases, digestive system diseases, and immune system diseases. Studies were screened independently by two reviewers, and an equal number of studies was randomly selected per calendric month. The primary outcome was the enrollment rate of women, calculated as the number of randomized women patients divided by the total number of randomized patients. Rates were weighted by their inverse variance; statistical significance was tested using general linear models (GLM). Results Out of 398 RCTs assessed for eligibility, 300 RCTs were included. The enrollment rate of women in all the examined fields was lower than 50%, except for immune system diseases [median enrollment rate of 68% (IQR 46 to 81)]. The overall median enrollment rate of women was 41% (IQR 27 to 54). The median enrollment rate of women decreased with older age of the trials’ participants [mean age of trials’ participants ≤ 45 years: 47% (IQR 30–64), 46–55 years: 46% (IQR 33–58), 56–62 years: 38% (IQR 27–50), ≥ 63 years: 33% (IQR 20–46), p < 0.001]. Methodological quality characteristics showed no significant association with the enrollment rates of women. Out of the 300 included RCTs, eleven did not report on the number of included women. There was no significant difference between these studies and the studies included in the analysis. Conclusions Women are being inadequately represented, in the selected medical fields analyzed in our study, in recent RCTs. Older age is a potential barrier for the enrollment of women in clinical trials. Low inclusion rates of elderly women might create a lack of crucial knowledge in the adverse effects and the benefit/risk profile of any given treatment. Factors that might hinder the participation of women should be sought and addressed in the design of the study.
