Aims: The aim of this study was to describe, analyze, and compare the survival, functional outcome, and complications of minimally invasive (MI) and non-invasive (NI) lengthening total femoral prostheses.
Patients And Methods: A total of 24 lengthening total femoral prostheses, 11 MI and 13 NI, were implanted between 1991 and 2016. The characteristics, complications, and functional results were recorded. There were ten female patients and ten male patients. Their mean age at the time of surgery was 11 years (2 to 41). The mean follow-up was 13.2 years (seven months to 29.25 years). A survival analysis was performed, and the failures were classified according to the Modified Henderson System.
Results: The overall implant survival was 79% at five, ten, and 20 years for MI prostheses, and 84% at five years and 70% at ten years for NI prostheses. At the final follow-up, 13 prostheses did not require further surgery. The overall complication rate was 46%. The mean revision-free implant survival for MI and NI prostheses was 59 months and 49 months, respectively. There were no statistically significant differences in the overall implant survival, revision-free survival, or the distribution of complications between the two types of prosthesis. Infection rates were also comparable in the groups (9% vs 7%; p = 0.902). The rate of leg-length discrepancy was 54% in MI prostheses and 23% in NI prostheses. In those with a MI prosthesis, there was a smaller mean range of movement of the knee (0° to 62° vs 0° to 83°; p = 0.047), the flexion contracture took a longer mean time to resolve after lengthening (3.3 months vs 1.07 months; p < 0.001) and there was a lower mean Musculoskeletal Tumor Society (MSTS) score (24.7 vs 27; p = 0.295).
Conclusion: The survival and complications of MI and NI lengthening total femoral prostheses are comparable. However, patients with NI prosthesis have more accurate correction of leg-length discrepancy, a better range of movement of the knee and an improved overall function.

The objective of this study was to evaluate the changes in enzymic activity, metabolites, and hematological responses during the first 56-d of arrival of newly received calves, which were qualified at reception as high-risk but diagnosed as clinically healthy. A total of 320 blood samples were taken from 64 crossbred bull calves (average initial body weight = 148.3 ± 1.

Background: Toxoplasma infections are highly prevalent worldwide and can cause serious complications in immunocompromised individuals and lead to congenital infections in neonates. Despite ongoing efforts to develop T. gondii vaccines, none have been developed.

Background: To identify the prognosis of Japanese patients with collecting duct carcinoma (CDC).
Methods: We used a hospital-based cancer registry data in Japan to extract CDC cases that were diagnosed in 2013, histologically confirmed, and determined the first course of treatment. We further investigated treatment modalities and estimated overall survival (OS) by the Kaplan-Meier method.

Objective: To report clinical outcomes of skeletally immature dogs with antebrachial deformities secondary to premature closure of the distal radial physis (PCDRP) treated with angular corrections and distraction osteogenesis using circular external skeletal fixation (CESF).
Study Design: Retrospective multi-institutional case series.
Animals: A total of 12 client-owned dogs with premature distal radial physeal closure.

To evaluate myocardial synchronized exercise and clinical prognosis in patients with heart failure preserved ejection fraction (HFpEF), we utilized two-dimensional speckle tracking (2D-STI) stratified strain imaging. We retrospectively summarized 146 patients diagnosed with HFpEF in our hospital from January 2022 to January 2023. 2D-STI combined with stratified strain imaging was used to measure the overall left ventricular global longitudinal strain (LVGLS), the sub-endocardium, mid-myocardium, sub-epicardium LS of the left ventricle, as well as the basal, intermediate, and apical LS, the peak strain dispersion (PSD) and the transmural pressure difference, the postsystolic shortening (PSS), and early systolic lengthening.
