Incidence of and Risk Factors for Contrast-Induced Nephropathy After Cardiac Catheterization in Japanese Patients

Objectives: Differences in the mechanisms of subtrochanteric and diaphyseal atypical femoral fractures (AFFs) have been speculated in studies that have analyzed differences in the patients’ backgrounds. However, the etiologies of each type of AFF have not been investigated in detail. Therefore, this study aimed to investigate the nature and etiologies of the risk factors for diaphyseal AFFs. Materials and Methods: Eighty consecutive Japanese patients with 91 diaphyseal AFFs (the AFF group) and 110 age-matched female patients with osteoporosis (the non-AFF control group) were included. Their clinical data were compared and the factors affecting AFFs were investigated. Furthermore, the etiologies of the risk factors for diaphyseal AFFs were examined. Results: Multivariate analysis revealed that femoral serrated changes, bisphosphonate or denosumab usage, and lateral and anterior femoral curvatures were the risk factors for diaphyseal AFFs (p<0.0011, p=0.0137, and p<0.0001, respectively). Multivariate analyses also revealed that serrated changes and low serum 25(OH)D levels affected the lateral curvature (p=0.0088 and 0.0205, respectively), while serrated changes affected the anterior curvature (p=0.0006); each significantly affected the femoral curvature. In addition, a high serum calcium (Ca) level, lateral femoral curvature, and anterior femoral curvature were the predictors of serrated changes (p=0.0146, 0.0002, and 0.0098, respectively). Conclusion: The risk factors for diaphyseal AFFs were bone resorption inhibitor usage, a strong femoral curvature, and serrated changes. A low serum 25(OH)D level and serrated changes are the risk factors for lateral curvature, while a high serum Ca level is a risk factor for serrated changes.

AbstractThe purpose of this study was to report the incidence of elevated intraocular pressure (IOP) after intravitreal injection (IVI) of anti-vascular endothelial growth factor (VEGF) in Japanese patients with age-related macular degeneration (AMD). A retrospective study of chart review of patients who underwent ≥ 10 intravitreal anti-VEGF injections between April 2009 and December 2019 was conducted. Elevated IOP was defined as IOP ≥ 25 mmHg at one visit. Cases with elevated IOP resulting from IVI were identified. Furthermore, the association between elevated IOP and some parameters, as the risk factors that influence elevated IOP, was investigated. A total of 402 eyes of 370 patients were included in this study. Twenty-eight eyes of 26 patients (7.0%) were identified as cases with elevated IOP after IVI. The mean time of elevation after baseline was 50.6 ± 26.5 months. History of glaucoma (p = 0.021; odds ratio, 5.85), treatment modality (p = 0.019; odds ratio, 6.32), and total number of injections (p = 0.003; odds ratio, 1.03) were significantly associated with elevated IOP. A late complication of elevated IOP is associated with IVI in patients with AMD. Particularly, history of glaucoma and treat and extend regimen with frequent injections were found to be risk factors of elevated IOP.

IntroductionType 1 diabetes (T1D) is associated with higher fracture risk. However, few studies have investigated the relationship between severe hypoglycemia and fracture risk in patients with T1D, and the results are controversial. Besides, none has investigated the risk factors for fracture in Asian patients with T1D. The aim of the present study was to investigate the prevalence of bone fracture and its relationship between severe hypoglycemia and other risk factors in Japanese patients with T1D.Research design and methodsThe single-center cross-sectional study enrolled 388 Japanese patients with T1D (mean age, 45.2 years; women, 60.4%; mean duration of diabetes, 16.6 years) between October 2019 and April 2020. The occurrence and circumstances of any fracture after the diagnosis of T1D were identified using a self-administered questionnaire. The main outcomes were any anatomic site of fracture and fall-related fracture. Severe hypoglycemia was defined as an episode of hypoglycemia that required the assistance of others to achieve recovery.ResultsA total of 92 fractures occurred in 64 patients, and 59 fractures (64%) were fall-related. Only one participant experienced fracture within the 10 years following their diagnosis of diabetes. In logistic regression analysis, the multivariate-adjusted ORs (95% CIs) of a history of severe hypoglycemia were 2.11 (1.11 to 4.09) for any fracture and 1.91 (0.93 to 4.02) for fall-related fracture. Fourteen of 18 participants with multiple episodes of any type of fracture had a history of severe hypoglycemia (p<0.001 vs no fracture).ConclusionsWe have shown that a history of severe hypoglycemia is significantly associated with a higher risk of bone fracture in Japanese patients with T1D.
