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%.

Objective: At present, the association of body mass index (BMI) with the prognosis of liver cirrhosis is controversial. Our retrospective study aimed to evaluate the impact of BMI on the outcome of liver cirrhosis.Methods: In the first part, long-term death was evaluated in 436 patients with cirrhosis and without malignancy from our prospectively established single-center database. In the second part, in-hospital death was evaluated in 379 patients with cirrhosis and with acute gastrointestinal bleeding (AGIB) from our retrospective multicenter study. BMI was calculated and categorized as underweight (BMI <18.5 kg/m2), normal weight (18.5 ≤ BMI < 23.0 kg/m2), and overweight/obese (BMI ≥ 23.0 kg/m2).Results: In the first part, Kaplan–Meier curve analyses demonstrated a significantly higher cumulative survival rate in the overweight/obese group than the normal weight group (p = 0.047). Cox regression analyses demonstrated that overweight/obesity was significantly associated with decreased long-term mortality compared with the normal weight group [hazard ratio (HR) = 0.635; 95% CI: 0.405–0.998; p = 0.049] but not an independent predictor after adjusting for age, gender, and Child–Pugh score (HR = 0.758; 95%CI: 0.479–1.199; p = 0.236). In the second part, Kaplan–Meier curve analyses demonstrated no significant difference in the cumulative survival rate between the overweight/obese and the normal weight groups (p = 0.094). Cox regression analyses also demonstrated that overweight/obesity was not significantly associated with in-hospital mortality compared with normal weight group (HR = 0.349; 95%CI: 0.096-1.269; p = 0.110). In both of the two parts, the Kaplan–Meier curve analyses demonstrated no significant difference in the cumulative survival rate between underweight and normal weight groups.Conclusion: Overweight/obesity is modestly associated with long-term survival in patients with cirrhosis but not an independent prognostic predictor. There is little effect of overweight/obesity on the short-term survival of patients with cirrhosis and with AGIB.

Objective To compare continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) with regard to long-term maintenance of access. Design Retrospective study of a four to six-year time period at one center. Patients One hundred and twenty-two CAPD patients between December 1988 and December 1992, and 172 HD patients between May 1986 and December 1992. Main Outcome Measure Cumulative survival rate of peritoneal catheters and arteriovenous fistulas (AVF) was the main outcome measure. Variables affecting the survival rate including sex, age, presence or absence of diabetes, and type of AVF (autogenous or prosthetic graft) were assessed. The causes of peritoneal catheter failures were analyzed. Results The cumulative survival rate of all peritoneal catheters was significantly longer than the AVF survival rate (84% vs 74% at one year; 73% vs 61% at two years; and 63% vs 48% at three years) (p = 0.029). There were no differences in peritoneal catheter survival according to sex, age, or diabetes. Compared with A VF survival, peritoneal catheter survival was significantly longer in male (p = 0.0492), elderly (p = 0.0082), and diabetic (p = 0.0022) patients. Prosthetic graft and old age were risk factors for AVF survival. Of all peritoneal catheter failures, infectious complications were responsible for 75% (33/44) and mechanical complications for 25% (11/44). Peritonitis was the leading infectious complication (21/33) and outflow obstruction was the leading mechanical complication (9/11). Conclusion In terms of long-term maintenance of access, CAPD is superior to HD, especially in the elderly or diabetics. Prevention and proper management of peritonitis may prolong the peritoneal catheter survival.

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.
