Background: Transcarotid and trans-subclavian access routes are increasingly used as alternative approaches for transcatheter aortic valve implantation (TAVI) when transfemoral access is not suitable. However, concerns remain about the risk of periprocedural stroke and long-term outcomes following transcarotid/trans-subclavian TAVI.
Aims: The present study sought to compare early and long-term outcomes of transcarotid/trans-subclavian TAVI versus transfemoral TAVI after propensity-score matching.
Methods: The 260 patients who underwent TAVI through a transfemoral (n=220), transcarotid (n=32) or trans-subclavian (n=8) approach at our institution over a 4-year period were identified. A 1:1 matching based on propensity score was performed, and led to a study population of 80 patients (40 transfemoral and 40 transcarotid/trans-subclavian). Primary endpoints were early complications; secondary endpoints were long-term outcomes.
Results: There were no differences in the baseline characteristics of the two groups. At 30 days after TAVI there were no significant differences between transfemoral and transcarotid/trans-subclavian TAVI in terms of death rates (5% vs 5%, respectively; P=1.00) and stroke rates (5% vs 2.5%, respectively; P=1.00). After a median follow-up of 21 months, the risk of death (P=0.95), stroke (P=0.82) and myocardial infarction (P=0.16) did not differ between the two groups.
Conclusions: After propensity-score matching, no significant differences in early and long-term outcomes were observed between transfemoral and transcarotid/trans-subclavian TAVI. These findings should encourage heart teams to consider a transcarotid or trans-subclavian approach when transfemoral access is unavailable.

This study compares and investigates the efficacy of 2 different surgical methods for early stage femoral head necrosis and analyze the factors affecting surgical outcomes and long-term femoral head survival. A retrospective analysis was conducted on the clinical data of 48 patients (52 hips) with femoral head necrosis who underwent either the Super-Path or Watson-Jones approach from January 1, 2016, to January 1, 2024. Harris scores at multiple time points before and after surgery were compared using repeated-measures analysis of variance (ANOVA), and a COX proportional hazards model was used to analyze risk factors.

Background: Digital technologies for type 2 diabetes mellitus (T2DM) care hold great potential to improve patients' health in the long term. Only a subset of telemedicine offerings are digital interventions that meet the criteria for prescribable digitale Gesundheitsanwendung (digital health apps; DiGAs) in Germany. Digital treatments further provide vast amounts of patient data that are important to generate evidence.

Background: Transgender and gender diverse (TGD) people seek gender-affirming care at any age to manage gender identities or expressions that differ from their birth gender. Gender-affirming hormone treatment (GAHT) and gender-affirming surgery may alter reproductive function and/or anatomy, limiting future reproductive options to varying degrees, if individuals desire to either give birth or become a biological parent.
Objective And Rationale: TGD people increasingly pursue help for their reproductive questions, including fertility, fertility preservation, active desire for children, and future options.

Case: We report a case of coccygeal dislocation complicated by defecatory dysfunction and discuss its treatment and mechanisms. A 58-year-old man was presented with coccygeal pain and defecatory dysfunction after sustaining an injury from a 1-m fall. Following diagnosis, a combined approach involving surgical treatment and physiotherapy was adopted, resulting in early symptom improvement and favorable long-term outcomes.
