[Clinical effect of simultaneous implantation and maxillary sinus floor elevation with or without bone graft].

PURPOSE: To investigate the difference of osteogenic effect and stability of maxillary sinus implants 6 months after maxillary sinus elevation with or without bone grafting. METHODS: A total of 150 patients with maxillary sinus floor lift and simultaneous implantation in Lishui People's Hospital from December 2019 to December 2021 were divided into group A (internal maxillary sinus lift + bone grafting) and group B (internal lift without bone grafting). Preoperative and postoperative CBCT data and implant stability of all patients were measured and analyzed to compare whether there were differences in clinical efficacy between the two groups. SPSS 25.0 software package was used for data analysis. RESULTS: A total of 199 implants were implanted, the implant retention rate was 97.6% in group A and 95.7% in group B one year after surgery, with no significant difference between the two groups(P＞0.05). There was no significant difference in residual bone height(RBH) and gray scale value (HU) between the two groups before and 6 months after operation (P＞0.05). There was no significant difference in ISQ value between the two groups during operation and 6 months after operation(P＞0.05). CONCLUSIONS: In cases with the remaining alveolar bone height of 3～8 mm and the planned lifting height of 3～4 mm, maxillary sinus floor lifting procedure achieved good clinical results in both groups with or without bone grafting, which indicated that bone grafting had little effect on retention rate and stability of the implants.

Comparative efficacy of different eating patterns in the management of type 2 diabetes and prediabetes: An arm-based Bayesian network meta-analysis.

AIMS/INTRODUCTION: Diet therapy is a vital approach to manage type 2 diabetes and prediabetes. However, the comparative efficacy of different eating patterns is not clear enough. We aimed to compare the efficacy of various eating patterns for glycemic control, anthropometrics, and serum lipid profiles in the management of type 2 diabetes and prediabetes. MATERIALS AND METHODS: We conducted a network meta-analysis using arm-based Bayesian methods and random effect models, and drew the conclusions using the partially contextualized framework. We searched twelve databases and yielded 9,534 related references, where 107 studies were eligible, comprising 8,909 participants. RESULTS: Eleven diets were evaluated for 14 outcomes. Caloric restriction was ranked as the best pattern for weight loss (SUCRA 86.8%) and waist circumference (82.2%), low-carbohydrate diets for body mass index (81.6%), and high-density lipoprotein (84.0%), and low-glycemic-index diets for total cholesterol (87.5%) and low-density lipoprotein (86.6%). Other interventions showed some superiorities, but were imprecise due to insufficient participants and needed further investigation. The attrition rates of interventions were similar. Meta-regression suggested that macronutrients, energy intake, and weight may modify outcomes differently. The evidence was of moderate-to-low quality, and 38.2% of the evidence items met the minimal clinically important differences. CONCLUSIONS: The selection and development of dietary strategies for diabetic/prediabetic patients should depend on their holistic conditions, i.e., serum lipid profiles, glucometabolic patterns, weight, and blood pressure. It is recommended to identify the most critical and urgent metabolic indicator to control for one specific patient, and then choose the most appropriate eating pattern accordingly.
