Question: Context: To investigate the recent incidence of T1D in a US Midwestern county to determine whether this increase has been sustained and compare it with the incidence of celiac disease (CD) and also investigate the prevalence of CD, an associated autoimmune disease, within the cohort.', 'A broad search strategy was used to identify all incident cases of T1D in Olmsted County, Minnesota, between January 1, 1994, and December 31, 2010, using the Rochester Epidemiology Project. Diagnosis and residency status were confirmed through the medical record. Incidence rates were directly standardized to the 2010 US population. Poisson regression was used to test for a change in incidence rate. Clinical charts were reviewed to confirm case status.', 'There were 233 incident cases of T1D. Directly adjusting for age and sex with respect to the 2010 US white population, the overall annual incidence of T1D was 9.2 (95% CI, 8.0-10.4) per 100,000 people per year among all ages and 19.9 (95% CI, 16.6-23.2) per 100,000 people per year for those younger than 20 years. There was no significant increase in the incidence of T1D over time (P=.45). Despite the overall stability in annual incidence, there was an initial increasing trend followed by a plateau. Of the 109 patients with T1D (47%) tested for CD, 12% (13) had biopsy-proven CD.
Answer: The incidence of T1D has stopped increasing in Olmsted County, Minnesota, in the most recent decade. Further studies are needed to confirm this finding and explore reasons for this plateau.

Answer: Is incidence of Type 1 Diabetes Increasing in a Population-Based Cohort in Olmsted County , Minnesota , USA?


Question: Context: To develop a method for quick identification of sun-dried and sulfur-fumigated Cimicifugae Rhizoma by Fourier transform infrared spectroscopy (FTIR).', 'The alcoholic and aqueous extracts of sun-dried and sulfur-fumigated Cimicifugae Rhizoma were analyzed and compared by FTIR combined with second derivative infrared spectroscopy.', 'FTIR spectra showed that there were some differences in the positions of infrared absorption peaks and the relative intensities in the alcoholic and aqueous extracts of sun-dried and sulfur-fumigated Cimicifugae Rhizoma, and the second derivative IR spectra clearly enhanced the spectral resolution of their differences. FTIR spectra showed that the new absorption peaks of Cimicifugae Rhizoma appeared and a part of original absorption peaks disappeared after sulfur-fumigation in aqueous extracts, while a lot of new absorption peaks appeared and the intensities of almost all absorption peaks significantly decreased after sulfur-fumigation in alcoholic extracts. Second derivative IR spectra showed that both sun-dried and sulfur-fumigated Cimicifugae Rhizoma extracted by water differed significantly from each other ranging from about 3 950 to 3 940 cm(-1), 3 850 to 3 800 cm(-1), 1 800 to 1 750 cm(-1), as well as from 1 400 to 1 350 cm(-1); Differences also existed between sun-dried and sulfur-fumigated Cimicifugae Rhizoma extracted by ethanol ranging from about 3 980 to 3 960 cm(-1), 3 850 to 3 800 cm(-1), and 1 500 to 1 460 cm(-1).
Answer: The FTIR method combined with the second derivative IR spectrum can be used to analyze and distinguish sun-dried and sulfur-fumigated Cimicifugae Rhizoma quickly and accurately. The developed method provides an efficient approach for the quality control of Chinese herbal medicines with its simplicity and strong specificity.

Answer: Do [ Quick identification and discrimination of sun-dried and sulfur-fumigated cimicifugae rhizoma by Fourier transform infrared spectroscopy ]?


Question: Context: Nondiagnostic fine-needle aspiration biopsy (ND-FNAB) of the thyroid leads to unnecessary thyroidectomy. The aims of this study were as follows: (1) to determine the risk of malignancy in ND-FNABs, and (2) to evaluate factors that may identify patients at risk for a ND-FNAB.', 'A total of 241 patients who underwent FNAB and thyroidectomy were evaluated for factors associated with a ND-FNAB.', 'A total of 215 women and 26 men underwent FNAB and thyroidectomy. ND-FNAs occurred in 51 of 241 (21%) patients. Ultrasound guidance did not reduce the likelihood of a ND biopsy. Patients with nodules greater than 3 cm had more ND-FNAs. Twenty-one of 51 with a ND biopsy underwent a repeat FNAB. Repeat FNAB was ND in 29% of patients. There was malignant disease in 7 of 51 (14%) with a ND-FNAB. Patient age, sex, thyroid function, gland size, multiple nodules, and final pathology were not related to a ND-FNAB (P > .05).
Answer: Most patients with a ND-FNAB have benign disease and low-risk patients with a ND-FNAB on repeat FNA warrant a more conservative approach.

Answer:
Are nondiagnostic thyroid fine-needle aspiration biopsies no longer a dilemma?
