AbstractThe accuracy of theFramingham risk score (FRS) in identifying patients with nonalcoholic fatty liver disease (NAFLD) at higher 10‐year coronary heart disease (CHD) risk remains unknown. We aimed at evaluating both the baseline probability ofCHDas predicted by theFRSand the actual long‐term occurrence ofCHDinNAFLDpatients. This was a longitudinal study of a community‐based cohort. A total of 309NAFLDpatients were followed up for 11.5 ± 4.1 years (total 3554 person‐years). The overall calculated 10‐yearCHDrisk was significantly higher in theNAFLDcohort than the absoluteCHDrisk predicted by theFRSfor persons of the same age and gender (10.9 ± 9.3% vs. 9.9 ± 5.9%, respectively,P < 0.0001), and higher in men than women (12.6 ± 10.3% vs. 9.6 ± 8.1%, respectively,P = 0.006). New onsetCHDoccurred in 34 patients (11% vs. 10.9% predicted at baseline,P = NS), whereas 279 (89%) patients did not developCHD. Using multivariable analysis, theFRSwas the only variable significantly associated with new onsetCHD(OR = 1.13, 95%CI = 1.05–1.21;P = 0.001). AFRScut‐point of 11 in women, and 6 in men had a sensitivity of 80% and 74%, respectively, and a negative predictive value of 97% and 93% respectively.NAFLDpatients have a higher 10‐yearCHDrisk than the general population of the same age and gender. TheFRSaccurately predicts the higher 10‐yearCHDrisk inNAFLDpatients, and helps identify those patients expected to derive the most benefit from early intervention to preventCHDevents.

Abstract Objective: To investigate the association of body mass index (BMI) and BMI change with change in prostate-specific antigen (PSA) level and to assess the possible roles of PSA hemodilution and prostate volume in explaining the obesity and PSA association. Methods: In 1990, a randomly selected cohort of Caucasian men, aged 40 to 79 years, from Olmsted County, Minnesota, completed questionnaires ascertaining demographic characteristics, current medical conditions, and medications biennially, with a subset undergoing blood draws and clinical examinations. Linear mixed models were used to predict annual changes and intercepts of individual changes in BMI, PSA, prostate volume, plasma volume, and PSA mass, adjusting for age in 545 men with at least 2 serial PSA, BMI, and prostate volume measurements. Results: Baseline BMI was inversely associated with the annual percent change in PSA, adjusting for age, baseline PSA, and prostate volume and for the rates of change in BMI and prostate volume (β = −0.003, 95% CI: −0.006 to −0.0003). Baseline obesity was positively associated with mean baseline levels and the rate of change in prostate volume (P = 0.002) and plasma volume (both P &lt; 0.001) but was not associated with either the mean baseline values or the rate of change in PSA mass. Conclusions: Baseline obesity was associated with baseline PSA and prostate volume and with the rate of change in PSA over 15 years of follow-up. Impact: The inverse association of obesity with prostate cancer diagnosis may be at least partly due to detection bias, which is due to larger prostate volumes and PSA hemodilution in obese men.

ABSTRACT Introduction The presence of erectile or ejaculatory dysfunction may indicate physical problems; however, individual perceptions (e.g., sexual satisfaction) may reflect the degree of concern about these changes. Long-term data showing how changes in multiple sexual function domains track together may be useful in understanding the importance of physical declines vs. sexual satisfaction. Aim The aim of this study was to describe changes in sexual function among a population-based sample of aging men. Methods A population-based cohort study using data from the Olmsted County Study of Urinary Symptoms and Health Status among Men. Sexual function was assessed biennially from 1996 to 2004 using a previously validated questionnaire in a random sample of 2,213 men. Main Outcome Measures Changes in erectile function, libido, ejaculatory function, sexual problems, and sexual satisfaction. Results Overall, we observed declines in all of the sexual function domains, ranging from an annual decrease of 0.03 point per year for sexual satisfaction to an annual decrease of 0.23 point per year in erectile function. Moderate correlations were observed among all longitudinal changes in sexual function (range in age-adjusted rs = 0.14–0.43); however, significantly smaller correlations between changes in the functional domains and changes in sexual satisfaction and problem assessment were observed among older men (range in age-adjusted rs = 0.03–0.29). Conclusion Overall, these results demonstrate that longitudinal changes in five sexual function domains change together over time in our community-based cohort. Erectile function, ejaculatory function, and sexual drive decrease over time with greater rates of decline for older men. However, older men may be less likely to perceive these declines as a problem and be dissatisfied. These data may prove helpful to patients and clinicians in understanding and discussing changes in multiple aspects of sexual function.

Objective To investigate 35‐year epidemiological trends in tonsillectomy and adenotonsillectomy. Study Design/Subjects Cross‐sectional survey. Subjects included all patients from birth to age 29 years who had tonsillectomy or adenotonsillectomy from 1970 to 2005. Results Study included 8106 patients (median age 8.0 years; range, 6 months to 29 years; male 3646 patients [45%]). Overall tonsillectomy incidence increased from 126 (95% confidence interval [CI], 111‐140) per 100,000 person‐years in 1970 through 1974 to 153 (95% CI, 139‐166) in 2000 through 2005. A dominant factor, adenotonsillectomy incidence rose sharply from 243 (95% CI, 223‐261) per 100,000 person‐years in 1970 through 1974 to 485 (95% CI, 462‐509) in 2000 through 2005. The indication of upper airway obstruction increased from 12 percent of patients in 1970 to 77 percent in 2005. Conclusions Epidemiological trends in tonsillectomy and adenotonsillectomy have shifted substantially. Overall numbers have increased, and surgical indications have shifted from infection to upper airway obstruction.
