- Cross-cultural adaptation and validation of the European Portuguese version of the heartland forgiveness scalePublication . Ikedo, Fabio; Castro, Luisa; Fráguas, Sofia; Rego, Francisca; Nunes, RuiBackground Forgiveness is linked with well-being, and social and health research has focused on the role and aspects of forgiveness that has been recently suggested as a phenomenon of public health importance. The Heartland Forgiveness Scale (HFS) was developed gathering three subscales to assess the forgiveness of others, forgiveness of self, and forgiveness of situation. The present study aimed to adapt the HFS into European Portuguese, and investigate its reliability and validity. Methods Translation and cross-cultural adaptation were conducted using a multistep forward-back translation process. Internal consistency was assessed by Cronbach’s alpha. Confirmatory factor analysis was conducted to verify that the factor structure is the same as in the original HFS. The short version of the Ruminative Response Scale (RRS) and the Satisfaction with Life Scale (SWLS) were used to examine convergent validity. Results A sample of 222 university students, selected through convenience sampling, was used to access the validity of the European Portuguese version of the HFS (EPHFS). Cronbach’s alpha for the European Portuguese HFS subscales were 0.777, 0.814 and 0.816 for Self, Others and Situation, respectively, indicating acceptable reliability. The 3-factor model of the original HFS was replicated in confirmatory factor analysis. As expected by evidence in the literature, positive and statistically significant correlations were found between SWLS and HFS and subscales. RRS showed negative and statistically significant correlations with HFS and subscales. Conclusions The European Portuguese version of the HFS presented acceptable internal consistency, construct validity and confirmed the three-factor structure of the original HFS.
- Impact of age, gender and body mass index on the efficacy of tranexamic acid in total knee arthroplastyPublication . Viegas, Rui; Kumar, Abhishek; Carvalho, Maria M.; Vide, João; Fontes, Ana Paula; Sousa, João P.Background: Tranexamic acid (TXA) is effective and safe in decreasing blood loss and transfusion rate in total knee arthroplasty (TKA). Few studies focused on the role of patients’ characteristics on the efficacy of TXA in TKA. The purpose of this study was to conduct a retrospective analysis to investigate if age, gender and BMI influence the efficacy of TXA in reducing perioperative blood loss in TKA. Methods: We did an observational study including 366 consecutive patients undergoing TKA in Hospital Particular do Algarve between January 2011 and April 2019 which were divided in two groups: intraoperative administration of intravenous TXA (TXA Group) and no administration of TXA (Control Group). The perioperative blood loss between groups and their relation with age, gender and BMI was compared. Results: Of the 366 patients, 225 (61%) received TXA. In both groups, age did not correlate to the blood loss. Women in the TXA group had less perioperative blood loss than in the control group. No such difference was found for men. The normal weight group showed no difference in perioperative blood loss with or without TXA administration. However, there was a statistically significant difference in the overweight and obese groups. The mean perioperative blood loss was higher in the control group (854±342 ml) than in the TXA group (720±335 ml). Conclusions: TXA administration is efficient in controlling TKA associated hemorrhage in overweight and obese individuals and in women but it doesn’t have that effect in normal weight patients or in men.
