BACKGROUND AND PURPOSE:Nodular goiter is one of the most common benign lesions in thyroid nodule. The main treatment of the disease is still the traditional surgical resection, however there are many problems such as general anesthesia, surgical scar, postoperative thyroid or parathyroid function abnormalities, and high nodules recurrence rate in residual gland. The purpose of this study was to compare the efficacy, safety, and cost-effectiveness of 2 treatment methods, surgery and radiofrequency ablation, for the treatment of benign thyroid nodules.
Background: The aim of the present 24-week multicentre randomized noninferiority trial was to compare the efficacy and safety of two insulin intensification strategies in uncontrolled type 2 diabetes despite optimized basal insulin therapy. Methods: Patients with fasting plasma glucose (FPG) <130 mg/dL and HbA1c 7.0%-10.0% while on insulin glargine were randomized to a basalprandial group (stepwise addition of insulin glulisine) or a premixed insulin group (insulin aspart/insulin aspart protamine 30/70 starting with 6 IU twice daily). The primary endpoint was the change in HbA1c after 24 weeks (noninferiority margin 0.4%). Results: At Week 24, the adjusted mean change from baseline HbA1c was -0.94 ± 0.09% and -1.04 ± 0.09% in basal-prandial and premixed insulin groups, respectively, with a mean difference of -0.09% (95% confidence interval [CI] -0.35, 0.16). A lower rate of hypoglycemia with a similar reduction in HbA1c was observed during stabilization of the total daily insulin dose in the premixed insulin group (Weeks 0-12). After stabilization of the total daily insulin dose, the rate of hypoglycemia and the total daily insulin dose were similar in the two groups. Conclusions: The efficacy and safety of the two intensifying regimens were similar after stabilization of the total daily insulin dose when oral agents were maintained. Starting with a lower total daily insulin dose with a gradual change in the treatment regimen was helpful in reducing the rate of hypoglycemia during initial stabilization of the total daily insulin dose.
The purpose of this study was to investigate risk factors of postoperative pneumonia (POP) after lung cancer surgery. The 417 lung cancer patients who underwent surgical resection in a tertiary referral hospital were included. Clinical, radiological and laboratory data were reviewed retrospectively. Male and female ratio was 267:150 (median age, 65 yr). The incidence of POP was 6.2% (26 of 417) and in-hospital mortality was 27% among those patients. By univariate analysis, age ≥ 70 yr (P < 0.001), male sex (P = 0.002), ever-smoker (P < 0.001), anesthesia time ≥ 4.2 hr (P = 0.043), intraoperative red blood cells (RBC) transfusion (P = 0.004), presence of postoperative complications other than pneumonia (P = 0.020), forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) < 70% (P = 0.002), diffusing capacity of the lung for carbon monoxide < 80% predicted (P = 0.015) and preoperative levels of serum C-reactive protein ≥ 0.15 mg/dL (P = 0.001) were related with risk of POP. Multivariate analysis showed that age ≥ 70 yr (OR = 3.563, P = 0.014), intraoperative RBC transfusion (OR = 4.669, P = 0.033), the presence of postoperative complications other than pneumonia (OR = 3.032, P = 0.046), and FEV1/FVC < 70% (OR = 3.898, P = 0.011) were independent risk factors of POP. In conclusion, patients with advanced age, intraoperative RBC transfusion, postoperative complications other than pneumonia and a decreased FEV1/FVC ratio have a higher risk for pneumonia after lung cancer surgery.
Multivariate analysis using total IEQ and IEQ/g as outcome variables indicated that age older than 2, being male and moderate distension by Liberase injection are major determinants influencing successful islet isolation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
