- BACKGROUND: The Power of Food Scale (PFS) was developed to assess the psychological impact of today's food-abundant environments. OBJECTIVE: To evaluate the structure of the PFS in diverse populations of obese and nonobese individuals. DESIGN: Data were obtained from obese adults in a clinical trial for a weight management drug (n=1741), and overweight, obese and normal weight adults in a Web-based survey (n=1275). Exploratory and confirmatory factor analyses were used to investigate the PFS structure using the clinical data. The model developed was then tested using the Web-based data. Relationships between PFS domains and body mass index (BMI) were examined. Logistic regression was used in the Web-based survey to evaluate the association between obesity status and PFS scores. RESULTS: Clinical data indicated that the scale was best represented by a 15-item version with three subscale domains and an aggregate domain (average of three domains); this was confirmed with data from the Web-based survey (Comparative Fit Index: 0.95 and 0.94 for the clinical and Web-based studies, respectively). Cronbach's alpha for both data sets was high, ranging from 0.81 to 0.91. The relationships between BMI and each domain were weak (and approximately linear). A full category increase in PFS domain score (range 1-5) increased the odds of being obese 1.6-2.3 times. CONCLUSIONS: The 15-item PFS is best represented by three domains and an aggregate domain. The PFS may provide a useful tool to evaluate the effects of obesity treatments on feelings of being controlled by food in an obesogenic food environment.

- BACKGROUND: The 21-item Three-Factor Eating Questionnaire (TFEQ-R21) is a scale that measures three domains of eating behavior: cognitive restraint (CR), uncontrolled eating (UE) and emotional eating (EE). OBJECTIVES: To assess the factor structure and reliability of TFEQ-R21 (and if necessary, refine the structure) in diverse populations of obese and non-obese individuals. DESIGN: Data were obtained from obese adults in a United States/Canadian clinical trial (n=1741), and overweight, obese and normal weight adults in a US web-based survey (n=1275). Confirmatory factor analyses were employed to investigate the structure of TFEQ-R21 using baseline data from the clinical trial. The model was refined to obtain adequate fit and internal consistency. The refined model was then tested using the web-based data. Relationships between TFEQ domains and body mass index (BMI) were examined in both populations. RESULTS: Clinical data indicated that TFEQ-R21 needed refinement. Three items were removed from the CR domain, producing the revised version TFEQ-R18V2 (Comparative Fit Index (CFI)=0.91). Testing TFEQ-R18V2 in the web-based sample supported the revised structure (CFI=0.96; Cronbach's coefficient alpha of 0.78-0.94). Associations with BMI were small. In the clinical study, the CR domain showed a significant and negative association with BMI. On the basis of the web-based survey, it was shown that the relationship between BMI and CR is population-dependent (obese versus non-obese, healthy versus diabetics). CONCLUSIONS: In two independent datasets, the TFEQ-R18V2 showed robust factor structure and good reliability. It may provide a useful tool for characterizing UE, CR and EE.

- To describe the contemporary features of coagulase-negative staphylococcal (CoNS) prosthetic valve endocarditis (PVE).Observational study of prospectively collected data from a multinational cohort of patients with infective endocarditis. Patients with CoNS PVE were compared to patients with Staphylococcus aureus and viridans streptococcal (VGS) PVE.The International Collaboration on Endocarditis-Prospective Cohort Study (ICE-PCS) is a contemporary cohort of patients with infective endocarditis from 61 centres in 28 countries.Adult patients in the ICE-PCS with definite PVE and no history of injecting drug use from June 2000 to August 2005 were included.None.Heart failure, intracardiac abscess, death.CoNS caused 16% (n = 86) of 537 cases of definite non-injecting drug use-associated PVE. Nearly one-half (n = 33/69, 48%) of patients with CoNS PVE presented between 60 days and 365 days of valve implantation. The rate of intracardiac abscess was significantly higher in patients with CoNS PVE (38%) than in patients with either S aureus (23%, p = 0.03) or VGS (20%, p = 0.05) PVE. The rate of abscess was particularly high in early (50%) and intermediate (52%) CoNS PVE. In-hospital mortality was 24% for CoNS PVE, 36% for S aureus PVE (p = 0.09) and 9.1% for VGS PVE (p = 0.08). Meticillin resistance was present in 68% of CoNS strains.Nearly one-half of CoNS PVE cases occur between 60 days and 365 days of prosthetic valve implantation. CoNS PVE is associated with a high rate of meticillin resistance and significant valvular complications.

- OBJECTIVE: To assess the (i) the overlap between voiding, storage, and postmicturition symptoms; and (ii) the relative effect of bother and implications for treatment seeking within these symptom groups, using data from the EpiLUTS study. SUBJECTS AND METHODS: This cross-sectional population-representative survey was conducted via the Internet in the USA, the UK and Sweden. Participants were asked to rate the frequency and symptom-specific bother of individual LUTS. Descriptive statistics were used to examine differences in International Continence Society LUTS subgroups. Logistc regressions were used with treatment seeking as the dependent variable and the bother of individual symptoms as predictors. RESULTS: The survey response rate was 59%. The sample included 30,000 participants (14,139 men and 15,861 women); 71% of men and 75% of women reported at least one LUTS, and about half reported LUTS from more than one symptom group. Rates of bother were greatest for those who reported multiple storage, voiding and postmicturition LUTS (men 83%, women 89%). Less than a third of participants with LUTS from all three groups reported seeking treatment. Consistent correlates of treatment seeking across genders included bother due to weak stream, incomplete emptying, perceived daytime frequency, nocturia and urgency. There were also significant associations for several types of incontinence, most commonly stress incontinence in women and leaking during sexual activity in men. Despite high rates of symptom overlap and symptom-specific bother, few participants sought treatment for LUTS. CONCLUSION: Common conditions such as BPH and OAB are treatable, and clinicians should proactively ask patients about urinary symptoms. Given the many types of LUTS that patients experience, it is imperative that clinicians assess all LUTS to ensure that appropriate treatments are prescribed.

- Enterococcal prosthetic valve infective endocarditis (PVE) is an incompletely understood disease. In the present study, patients with enterococcal PVE were compared to patients with enterococcal native valve endocarditis (NVE) and other types of PVE to determine differences in basic clinical characteristics and outcomes using a large multicenter, international database of patients with definite endocarditis. Forty-five of 159 (29%) cases of definite enterococcal endocarditis were PVE. Patients with enterococcal PVE were demographically similar to patients with enterococcal NVE but had more intracardiac abscesses (20% vs. 6%; p=0.009), fewer valve vegetations (51% vs. 79%; p<0.001), and fewer cases of new valvular regurgitation (12% vs. 45%; p=0.01). Patients with either enterococcal PVE or NVE were elderly (median age, 73 vs. 69; p=0.06). Rates of in-hospital mortality, surgical intervention, heart failure, peripheral embolization, and stroke were similar in both groups. Patients with enterococcal PVE were also demographically similar to patients with other types of PVE, but mortality may be lower (14% vs. 26%; p=0.08). Notably, 93% of patients with enterococcal PVE came from European centers, as compared with only 79% of patients with enterococcal NVE (p=0.03). Thus, patients with enterococcal PVE have higher rates of myocardial abscess formation and lower rates of new regurgitation compared to patients with enterococcal NVE, but there are no differences between the groups with regard to surgical or mortality rates. In contrast, though patients with enterococcal PVE and patients with other types of PVE share similar characteristics, mortality is higher in the latter group. Importantly, the prevalence of enterococcal PVE was higher in the European centers in this study.

- The purpose of this investigation was to study the influence of diabetes mellitus (DM) on outcomes of infective endocarditis (IE). Outcomes were compared between 150 diabetic and 905 non-diabetic patients with IE from the International Collaboration on Endocarditis Merged Database. Compared to non-diabetic patients, diabetic patients were older (median age 63 vs 57 y, p<0.001), were more often female (42.0% vs 31.9%, p=0.01), more often had comorbidities (41.5% vs 26.7%, p<0.001), and were more likely to be dialysis dependent (12.7% vs 4.0%, p<0.001). S. aureus was isolated more often (30.7% vs 21.7%, p=0.02), and microorganisms from the viridans Streptococcus group less often (16.7% vs 28.2%, p = 0.001) in the diabetic group. There was no difference with respect to the presence of congestive heart failure, embolism, intra-cardiac abscess, new valvular regurgitation, or valvular vegetation. Diabetic patients underwent surgical intervention less frequently (32.0% vs 44.9%, p = 0.003), and had higher overall in-hospital mortality (30.3% vs 18.6%, p = 0.001). On multivariable analysis, DM was an independent predictor of mortality (odds ratio (OR) = 1.71, 95% confidence interval (CI) 1.08-2.70), especially in male patients, as diabetic males had higher mortality than non-diabetic males (OR 2.18, CI 1.08-4.35). DM is an independent predictor of in-hospital mortality among patients hospitalized with IE.

- PURPOSE: To describe clinical features and outcomes of enterococcal left-sided native valve endocarditis and to compare it to endocarditis caused by other pathogens. SUBJECTS AND METHODS: Patients in the International Collaboration on Endocarditis-Merged Database were included if they had left-sided native valve endocarditis. Demographic characteristics, clinical features, and outcomes were analyzed. Multivariable analysis evaluated enterococcus as a predictor of mortality. RESULTS: Of 1285 patients with left-sided native valve endocarditis, 107 had enterococcal endocarditis. Enterococcal endocarditis was most frequently seen in elderly men, frequently involved the aortic valve, tended to produce heart failure rather than embolic events, and had relatively low short-term mortality. Compared to patients with non-enterococcal endocarditis, patients with enterococcal endocarditis had similar rates of nosocomial acquisition, heart failure, embolization, surgery, and mortality. Compared to patients with streptococcal endocarditis, patients with enterococcal endocarditis were more likely to be nosocomially acquired (9 of 59 [15%] vs 2 of 400 [1%]; P <.0001) and have heart failure (49 of 107 [46%] vs 234 of 666 [35%]; P = 0.03). Compared to patients with S. aureus endocarditis, patients with enterococcal endocarditis were less likely to embolize (28 of 107 [26%] vs 155 of 314 [49%]; P <.0001) and less likely to die (12 of 107 [11%] vs 83 of 313 [27%]; P = 0.001). Multivariable analysis of all patients with left-sided native valve endocarditis showed that enterococcal endocarditis was associated with lower mortality (odds ratio [OR] 0.49; 95% confidence interval [CI] 0.24 to 0.97). CONCLUSIONS: Enterococcal native valve endocarditis has a distinctive clinical picture with a good prognosis.
