Abstract The All-on-Four treatment concept provides patients with an immediately loaded fixed prosthesis supported by 4 implants. This single-center retrospective study evaluated the concept while using the NobelActive implant (Nobel Biocare, Gothenburg, Sweden). Seven hundred eight implants placed in 165 subjects demonstrated a cumulative survival rate of 99.6% (99.3% in maxilla and 100% in the mandible) for up to 29 months of loading. The definitive prosthesis survival rate was 100%.

Although a number of approaches to implant-supported restoration of severely atrophic maxillae and mandibles have been developed, most of these treatments are costly and protracted. An exception is the All-on-Four concept, which uses only 4 implants to support an acrylic, screw-retained provisional prosthesis delivered on the day of implant placement, followed by a definitive prosthesis approximately 4 months later. After the introduction of a new implant design in 2008, a new protocol was developed for provisionally treating patients with severely atrophic jaws using the All-on-Four concept and 3.5-mm-diameter implants. This article describes that protocol and reports on the results of 227 implants after 1 to 3 years of follow-up. The cumulative survival rate was 98.7% at the end of 3 years, with a 100% prosthetic survival rate. Combining the 3.5-mm-diameter NobelActive implants with the All-on-Four concept promises to become a new standard of care for severely compromised patients.

Abstract The aim of this study was to prospectively evaluate treatment outcomes of 1-piece implants (NobelDirect and NobelPerfect, Nobel Biocare AB, Gothenberg, Sweden) in routine private clinical practice. Forty-seven implants placed in 30 subjects demonstrated a cumulative survival rate of 97.9% with stable marginal bone levels after 4 years of loading.

The purpose of the study was to analyze the clinical effect of stereotactic radiosurgery (SRS) (Cyberknife) on hepatocellular carcinoma with portal vein tumor thrombosis (HCC-PVTT). Data from 50 patients with HCC-PVTT who received Cyberknife from August 2013 to April 2016 was collected for efficacy analysis. Moreover, survival correlation was evaluated by Cox proportionalhazards model. The total effective rate in 1–3 months after treatment was 64.00%, including 7 cases in complete remission, 12 cases in partial remission, 13 cases in stable conditions, and 18 cases with enlargement; a 4–24-months follow-up (with an average of 11.58 ± 2.58 months) showed that median survival, 1-year cumulative survival rate, and 2-year cumulative survival rate were, respectively, 11.86 ± 1.79 months, 48.00%, and 20.00%. Moreover, the Cox proportional-hazards model indicates that it was with no correlation between lesion diameter, classification of liver function, pre-operative alphafetoprotein, types of hepatitis, number of tumors, ascites, types of tumor emboli, total dose, and survival rate. SRS is effective for HCC-PVTT and serves as an ideal treatment clinically to help preserve patients’ lives, which is worthy of clinical promotion and application.

Abstract Background: The management of hip fractures is nowadays mainly performed in Orthogeriatric Units, one of whose fundamental tools is the application of geriatric scores. The purpose of this study is to establish the potential usefulness of Barthel Index, Katz Index, Lawton-Brody Index and Physical Red Cross Scale geriatric scores as predictors of survival rate and readmission rate in older patients after hip fracture surgery. Methods: We designed a prospective single-center observational study, including 207 older adults over age 65 who underwent hip fracture surgery in the first half of 2014 and followed up to September 2018. Cumulative survival and readmission rates were analyzed by Kaplan-Meier; group comparison, by Log-Rank and hazard ratio, by Cox regression. Results: We found statistical differences (p<0.001) for cumulative survival rate by every geriatric score analyzed (BI HR=0.98 [0.97,0.99]; KI HR=1.24 [1.13-1.37]; LBI HR= 1.25 [1.16, 1.36]; PCRS HR=1.67 [1.37,2.04]). Furthermore, we could determinate an inflection point for survival estimation by Barthel Index (BI 0-55/60-100*, p<0.001, HR=2.37 [1.59,3.53]), Katz Index (KI A-B*/C-G, p<0.001, HR=2.66 [1.80, 3.93], and Lawton-Brody Index (LBI 0-3/4-8*, p<0.001, HR=3.40 [2.09,5.25]). We reveal a correlation of the Charlson Index (p=0.002) and Katz Index (p=0.041) with number of readmissions for the study period. Conclusions: The geriatric scores analyzed are related to the cumulative survival rate after hip fracture surgery for more than 4 years, independently of other clinical and demographic factors. Katz Index in combination with Charlson Index could also be a potential predictor of the number of readmissions after surgery for hip fracture patients.
