Long-term Retrospective Study on Cumulative Survival Rate of Implants with Guided Bone Regeneration

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.

Term Maintenance

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.
