Health-Related Quality of Life for Eating Disorders questionnaire version-2 was responsive 1-year after initial assessment

OBJECTIVES: To assess the responsiveness of the Health-Related Quality of Life for Eating Disorders questionnaire version-2 (HeRQoLEDv2) and present the psychometric characteristics of a new binge domain. STUDY DESIGN AND SETTING: Patients with an eating disorder completed the HeRQoLEDv2, the Eating Attitudes Test-26, Short Form Health Survey-12, and two items from the Eating Disorder Inventory-2, at baseline and after 1 year. At the second assessment, patients completed the HeRQoLEDv2, as part of the battery of tests, along with health transitional questions. Validity and reliability analyses of the new binge domain were performed. Responsiveness was evaluated using distributional and anchor-based approaches, comparison of mean changes, mean change correlations, the minimal detectable change (MDC) at the individual and group level, and the minimal important difference (MID). RESULTS: Items in the binge domain loaded above 0.40. Cronbach alpha was 0.82. Regarding responsiveness, the mean changes detected by the HeRQoLEDv2 correlated above 0.30 with the criterion measures. Patients who reported improvement showed significant changes, and effect sizes above 0.30. The MDC(90%ind) was larger than the MID. CONCLUSION: The HeRQoLEDv2 includes the new binge domain. It responded to change at the group level. Further research regarding the MID is needed.     

Arylesterase activity and antioxidant status depend on PON1-Q192R and PON1-L55M polymorphisms in subjects with increased risk of cardiovascular disease consuming walnut-enriched meat

Human paraoxonase (PON1) exists in 2 major polymorphic forms and has been shown to protect LDL and HDL against oxidation. The aim of this study was to assess the differences between subjects at increased risk of cardiovascular disease (CVD), taking into account the effects of PON1-Q192R and PON1-L55M polymorphisms on 1) basal serum arylesterase activity, lipid peroxidation (LPO), and LDL-cholesterol (LDL-C), HDL-C, total cholesterol (TC), and oxidized-LDL (ox-LDL) concentrations; 2) the relations between arylesterase activity and lipid variables; and 3) the effect of walnut-enriched meat (WM) consumption on arylesterase activity and lipid variables. Twenty-three Caucasians at increased risk of CVD were randomly assigned to diet order groups in a crossover, nonblinded, placebo-controlled trial, consisting of two 5-wk experimental periods [WM and control meat (CM)]. Significant PON1-L55M x PON1-Q192R interactions affected basal serum HDL-C (P = 0.019), LDL-C (P = 0.028) and TC (P = 0.022) and tended to affect arylesterase activity (P = 0.083). Basal arylesterase activity was positively correlated with basal HDL-C (r = 0.53; P < 0.05) and TC (r = 0.43; P < 0.05) and negatively correlated with LPO (r = -0.70; P < 0.01) and the ox-LDL:LDL ratio (r = -0.63; P < 0.01). WM decreased arylesterase activity in PON1-55M carriers (P = 0.012) but not in PON1-L55 individuals, and decreased LPO concentrations in PON1-192R carriers (P = 0.031) but not in PON1-Q192 subjects. To conclude, serum TC, HDL-C, and LDL-C concentrations and arylesterase activity depend on the interaction of PON1-L55M and PON1-Q192R polymorphisms. However, the PON1-Q192R polymorphism is more closely related to antioxidant status. Both polymorphisms modulate the effect of WM consumption on CVD biomarkers.     

Internal migration in Spain in the 20th century: a new focus for the study of social inequalities in health

Objective

Catalonia and the Basque Country received substantial immigration quotas from the rest of Spain during the twentieth century. This study aimed to analyze inequalities in health by birthplace (the population born in the same region or other autonomous regions) in these two geographical areas.

Methods

We conducted a cross-sectional study in the non-institutionalized population aged 50 to 79 years, with data from the health surveys of Catalonia 2006 (n = 5,483) and the Basque Country 2007 (n = 3,424). We used log-binomial models to estimate the prevalence ratios (PR) of poor self-rated health by birthplace, stratified by sex and social class, and successively adjusted for age, social class and educational attainment.

Results

Immigrants from other autonomous regions had poorer self-rated health than the native-born population, both in the Basque Country (age-adjusted PR in men 1.30, 95% CI 1.11-1.54; women 1.42, 95% CI 1.25-1.62,) and in Catalonia (PR in men 1.41, 95% CI 1.26-1.62; PR in women 1.25, 95% CI 1.16-1.35). PRs were reduced but remained significant after adjustment for social class and educational attainment and stratification by manual or non-manual social class.

Conclusions

In both communities there are health inequalities that are detrimental to the immigrant population from the rest of Spain, which constitutes approximately half of the population in the studied age cohorts. Future studies should explore the persistence of these inequalities in other health indicators and their reproduction in second generations, and identify entry points for preventive policies.     

MRI and ultrasonography in Morton's neuroma: Diagnostic accuracy and correlation

Background:

The diagnosis of Morton''s neuroma is based primarily on clinical findings. Ultrasonography (US) and magnetic resonance image (MRI) studies are considered complementary diagnostic techniques. The aim of this study was to establish the correlation and sensitivity of both techniques used to diagnose Morton''s neuroma.

Materials and Methods:

Thirty seven patients (43 intermetatarsal spaces) with Morton''s neuroma operated were retrospectively reviewed. In all cases MRI or ultrasound was performed to complement clinical diagnosis of Morton''s neuroma. In all cases, a histopathological examination confirmed the diagnosis. Estimates of sensitivity were made and correlation (kappa statistics) was assessed for both techniques.

Results:

Twenty seven women and 10 men participated with a mean age of 60 years. Double lesions presented in six patients. The second intermetatarsal space was affected in 10 patients and the third in 33 patients. An MRI was performed in 41 cases and a US in 23 cases. In 21 patients, both an MRI and a US were performed. With regard to the 41 MRIs performed, 34 were positive for Morton''s neuroma and 7 were negative. MRI sensitivity was 82.9% [95% confidence interval (CI): 0.679–0.929]. Thirteen out of 23 US performed were positive and 10 US were negative. US sensitivity was 56.5% (95% CI: 0.345–0.768). Relative to the 21 patients on whom both techniques were carried out, the agreement between both techniques was poor (kappa statistics 0.31).

Conclusion:

Although ancillary studies may be required to confirm the clinical diagnosis in some cases, they are probably not necessary for the diagnosis of Morton''s neuroma. MRI had a higher sensitivity than US and should be considered the technique of choice in those cases. However, a negative result does not exclude the diagnosis (false negative 17%).     

Switch arterial paliativo como primer tiempo hacia Fontan en pacientes con fisiología univentricular y estenosis subaórtica

Introduction and objectives

There are several techniques for the palliative treatment of patients with single-ventricle physiology, ventriculoarterial discordance and subaortic stenosis. The Fontan procedure relies on optimal initial palliation to avoid the development of subaortic stenosis (as well as ventricular hypertrophy and diastolic dysfunction).

Methods

We present seven patients with single-ventricle physiology, transposition of the great arteries and subaortic stenosis, with low systemic output and high pulmonary flow, aged 21 to 383 days (median, 75) and weighing between 3.4 and 9.6 kg (median, 4.2). All were treated with a palliative arterial switch, thus «switching» their subaortic stenosis to subpulmonary stenosis. Six patients also underwent aortic arch surgery, 4 an atrial septectomy, and 1 a subaortic membrane resection.

Results

One patient died after surgery, another developed recoarctation, which was treated with an angioplasty, 3 patients reached the Glenn stage and 2 the Fontan stage. All had good ventricular function.

Conclusions

A palliative switch is an effective initial treatment for single-ventricle physiology with transposition of the great arteries and subaortic stenosis. This complex initial technique produces good results and allows the patient to progress to the Glenn or Fontan stage.Full English text available from:www.revespcardiol.org/en
