Abstract
BACKGROUND & AIMS Limited prospective studies have examined the association between legumes consumption and mortality, whereas scarce, if at all, previous studies have evaluated such associations taking into consideration specific grain legumes. We aimed to investigate the association between total legumes consumption and grain legumes species (dry beans, chickpeas, lentils, and fresh peas) with all-cause, cardiovascular disease (CVD), cancer and other-cause mortality among elderly Mediterranean individuals at high CVD risk. METHODS We prospectively assessed 7216 participants from the PREvención con DIeta MEDiterránea study. Dietary intake was assessed at baseline and yearly during follow-up by using a validated food frequency questionnaire. RESULTS During a median follow-up of 6.0 years, 425 total deaths, 103 CVD deaths, 169 cancer deaths and 153 due to other-causes deaths occurred. Hazard ratios (HRs) [95% confidence interval (CI)] of CVD mortality were 1.52 (1.02-2.89) (P-trend = 0.034) and 2.23 (1.32-3.78) (P-trend = 0.002) for the 3rd tertile of total legumes and dry beans consumption, respectively, compared with the 1st tertile. When comparing extreme tertiles, higher total legumes and lentils consumption was associated with 49% (HR: 0.51; 95% CI: 0.31-0.84; P-trend = 0.009) and 37% (HR: 0.63; 95% CI: 0.40-0.98; P-trend = 0.049) lower risk of cancer mortality. Similar associations were observed for CVD death in males and for cancer death in males, obese and diabetic participants. CONCLUSIONS These findings support the benefits of legumes consumption for cancer mortality prevention which may be counterbalanced by their higher risk for CVD mortality.

Abstract
BACKGROUND Heart failure (HF) is a major problem in developed countries. However, its relationship with obesity remains unclear, especially in low-risk populations. The objective of the study was to analyze the relationship between obesity and HF in a low-risk Mediterranean population. HYPOTHESIS Obesity is an independent predictor for HF. METHODS A prospective community-based population cohort study with 10 years' follow-up was conducted at 2 healthcare centers in the city of Barcelona, Spain. From a registered population of 35 275, the study included 932 randomly selected patients without HF, age 35-84 years. Obesity was defined as body mass index (BMI) ≥30 and HF according to European Society of Cardiology guidelines, confirmed by echocardiography. Cox proportional hazards regression was used to examine the association between obesity and heart failure. RESULTS The difference in HF incidence between obese subjects (4.7%) and nonobese subjects (1.6%) was 3.1% (95% confidence interval [CI]: 0.7-5.5). In the unadjusted model, incident HF was significantly associated with BMI: the hazard ratio [HR] was 1.09 for every 1 kg/m² increase (95% CI: 1.05-1.14) and 3.01 for BMI ≥30 (95% CI: 1.34-6.77). After adjusting for age, sex, hypertension, ischemic heart disease, and diabetes mellitus, the results were similar: HR 1.06 (95% CI: 1.01-1.10) and HR 2.45 for BMI ≥30 (95% CI: 1.02-5.61). Overweight was not associated with HF in any of the models. The population-attributable risk of HF due to obesity was 43.0% (95% CI: 13.9-74.9). CONCLUSIONS High rate differences, HRs, and attributable risk indicate that obesity is an important risk factor for incident HF.

Abstract
Misreporting characterized by the reporting of implausible energy intakes may undermine the valid estimation of diet-disease relations, but the methods to best identify and account for misreporting are unknown. The present study compared how alternate approaches affected associations between selected dietary factors and body mass index (BMI) by using data from the European Prospective Investigation Into Cancer and Nutrition-Spain. A total of 24,332 women and 15,061 men 29-65 years of age recruited from 1992 to 1996 for whom measured height and weight and validated diet history data were available were included. Misreporters were identified on the basis of disparities between reported energy intakes and estimated requirements calculated using the original Goldberg method and 2 alternatives: one that substituted basal metabolic rate equations that are more valid at higher BMIs and another that used doubly labeled water-predicted total energy expenditure equations. Compared with results obtained using the original method, underreporting was considerably lower and overreporting higher with alternative methods, which were highly concordant. Accounting for misreporters with all methods yielded diet-BMI relations that were more consistent with expectations; alternative methods often strengthened associations. For example, among women, multivariable-adjusted differences in BMI for the highest versus lowest vegetable intake tertile (β = 0.37 (standard error, 0.07)) were neutral after adjusting with the original method (β = 0.01 (standard error, 07)) and negative using the predicted total energy expenditure method with stringent cutoffs (β = -0.15 (standard error, 0.07)). Alternative methods may yield more valid associations between diet and obesity-related outcomes.

Abstract
To study if antibiotic treatment of outpatients had triggered Clostridium difficile infections (CDI), prescription numbers were compared with CDI-affected patient numbers. A strong correlation was observed for ciprofloxacin (R=0.917), suggesting that increased use of ciprofloxacin by outpatients contributed to increased numbers of CDI. These findings deserve further investigation as they may have an impact on future decisions regarding antibiotic prescribing.

Abstract
Findings on the association of alcohol consumption and oxidation of low-density lipoprotein (LDL), which is thought to play a crucial role in the generation of atherosclerotic lesion, are inconsistent. The aim of the present study was to investigate the association of total alcohol consumption and type of alcoholic beverage with circulating plasma LDL oxidation. This cross-sectional study included data of circulating oxidized LDL (ox-LDL) from a subpopulation of 587 men and women enrolled in a population-based survey conducted in 2000 in Girona (Spain). Multivariate analysis was performed to describe the independent association of alcohol consumption and ox-LDL. Increasing alcohol consumption was associated with high in vivo ox-LDL levels in the present population. The consumption of 10 g of alcohol was associated with an increase of 2.40 U/L of ox-LDL (p = 0.002). Adjustment for dietary variables, leisure-time physical activity, educational level, smoking, LDL-cholesterol, high-density lipoprotein-cholesterol, glycemia, triglycerides, diabetes, body mass index, waist circumference, and systolic and diastolic blood pressures only slightly modified this association (p = 0.003). In this full adjusted model the consumption of 10 g of alcohol per day was associated with an increase of 2.11 U/L of ox-LDL. Consumption of wine (ml/day) was associated with increasing ox-LDL levels (p = 0.029), however, attenuated after controlling for alcohol. No significant relationship of ox-LDL with alcohol-independent consumption of wine, beer, and spirits was observed. Alcohol consumption was independently and directly associated with circulating ox-LDL in the present population.

Abstract
The aim of the present study was to evaluate whether olive oils high in phenolic compounds influence the oxidative/antioxidative status in humans. Healthy men (n = 12) participated in a double-blind, randomized, crossover study in which 3 olive oils with low (LPC), moderate (MPC), and high (HPC) phenolic content were given as raw doses (25 mL/d) for 4 consecutive days preceded by 10-d washout periods. Volunteers followed a strict very low-antioxidant diet the 3 d before and during the intervention periods. Short-term consumption of olive oils decreased plasma oxidized LDL (oxLDL), 8-oxo-dG in mitochondrial DNA and urine, malondialdehyde in urine (P < 0.05 for linear trend), and increased HDL cholesterol and glutathione peroxidase activity (P < 0.05 for linear trend), in a dose-dependent manner with the phenolic content of the olive oil administered. At d 4, oxLDL after MPC and HPC, and 8-oxo-dG after HPC administration (25 mL, respectively), were reduced when the men were in the postprandial state (P < 0.05). Phenolic compounds in plasma increased dose dependently during this stage with the phenolic content of the olive oils at 1, 2, 4, and 6 h, respectively (P < 0.01). Their concentrations increased in plasma and urine samples in a dose-dependent manner after short-term consumption of the olive oils (P < 0.01). In conclusion, the olive oil phenolic content modulated the oxidative/antioxidative status of healthy men who consumed a very low-antioxidant diet.

Abstract
An 8-year-old boy with a 21/2 year history of portal hypertension and repeated bleedings from esophageal varices, was referred for treatment. The 3.5-cm-long occlusion of the portal vein was passed and the channel created was stabilized with a balloon-expandable stent; a portosystemic stent-shunt was also created. The portosystemic shunt closed spontaneously within 1 month, while the recanalized segment of the portal vein remained open. The pressure gradient between the intrahepatic and extrahepatic portal vein branches dropped from 17 mmHg to 0 mmHg. The pressure in the portal vein dropped from 30 mmHg to 17 mmHg and the bleedings stopped. The next dilation of the stent was performed 12 months later due to an increased pressure gradient; the gastroesophageal varices disappeared completely. Further dilation of the stent was planned after 2, 4, and 6 years.

Abstract
Because previous PCR-based methodologies for detection of minimal residual disease (MRD) in leukemia patients have been too cumbersome to allow for widespread clinical usefulness, we have employed a real-time quantitative PCR (RQ-PCR) system to develop an MRD assay for t(12;21). We initially determined the expression of the different alternatively spliced TEL-AML1 mRNAs found in t(12;21) breakpoint variants I and II. We then optimized PCR primers for the RQ-PCR system and, using the t(12;21)+ REH cell line in spiking experiments, found a linear detection of TEL-AML1 over at least five logs. Moreover, 1 malignant cell in a background of 1,000,000 normal cells could be detected. The expression of the GAPDH, ABL, and beta(2)-microglobulin (beta2M) housekeeping genes were then compared in normal donors and in leukemic patients, and the very stably expressed beta2M was selected as an internal reference gene, allowing us to compensate for variation in RNA quality and day-to-day variation. In 12 samples from t(12;21)-positive patients at diagnosis, the levels of the TEL-AML1 fusion transcripts were found to vary up to 14-fold after normalization to beta2M. Interestingly, in samples obtained from seven patients at diagnosis, during induction chemotherapy, or relapse, the level of TEL-AML1 in peripheral blood (PB) and bone marrow (BM) was found to differ only by threefold, suggesting that MRD may be evaluated in PB samples in most patients. We conclude that this assay could set new standards for t(12;21) MRD detection with its accuracy, its high throughput, and its short turnover time for samples.

Abstract
UNLABELLED The combination of weight discordance and prematurity implies a high perinatal morbidity and mortality for the affected twins. Several pathomechanisms may be responsible for the weight difference in twins including a different genetic growth potential in dizygotic twins, placenta insufficiency in one twin, and chronic feto-fetal transfusion (CFFT). Little is known about neonatal morbidity and mortality of discordant twins. Therefore, a retrospective, case-controlled study on preterm discordant twins up to 34 weeks gestation was carried out. Twenty-seven (27,3%) of 99 twin pairs born in our clinic had a birth weight difference of more than 20%. The control group consisted of 27 non-discordant twins matched for gestational age. Discordant twins showed a significantly higher mortality (19%) than the control twins (2%). Severe intracranial haemorrhage (ICH) and persistent ductus arteriosus Botalli (PDA) were found more often in discordant twins than in the control group. The increased mortality and morbidity of discordant twins compared with concordant twins matched for gestational age indicates that the increased morbidity and mortality of preterm weight discordant twins is not only due to prematurity, but is also related to the discordance itself. Thirteen (48.1%) of the weight discordant twin pairs fulfilled the criteria for CFFT. Twins with CFFT differed significantly from controls with respect to the incidence of mortality and the rate of severe ICH, PDA, and the necessity of postnatal cardiopulmonary resuscitation. By contrast, no significant differences were found between discordant twins without CFFT and controls. Thus, CFFT appears to be a major contributing factor for increased mortality and morbidity of weight discordant twins. Intra-twin pair analysis revealed a higher rate of postnatal hypoglycaemia in the smaller twins only, probably caused by insufficient glycogen storage due to intra-uterine malnutrition. Mortality was the same for both the larger and the smaller twins. It may be concluded that neonatal outcome of smaller twins who have survived intra-uterine malnutrition is the same as in larger twins. Intra-twin pair analysis in twins with CFFT revealed no significant differences except for a higher rate of ICH grade 2-4 in the larger twins which might be explained by hypervolaemia of the recipient. CONCLUSION Morbidity and mortality of weight discordant twins are increased. CFFT appears to be a major contributing factor for the increased mortality and morbidity. Postnatal mortality was the same in acceptor and donor; however, the acceptor had a higher postnatal morbidity.

Abstract
A standardized in-house reference extract from the pollen of Parthenium hysterophorus, which is responsible for the high incidence of allergic rhinitis in India, was generated and examined by skin test, radio-allergosorbent test inhibition and isoelectric focusing. Parthenium reference allergen discs and positive reference serum were also generated. These reference reagents could not only be used for the quantitation of Parthenium-specific IgE in the sera of rhinitis patients but also for the evaluation of allergenic activity (relative potency and lot-to-lot variation) of different batches of Parthenium pollen.

Abstract
In order to explore idiotypic, anti-idiotypic, and anti-anti-idiotypic responses to allergens, BALB/c mice were immunized with affinity-purified human idiotypic antibodies directed against a highly purified shrimp allergen. This resulted in the production of anti-idiotypic antibodies which were quantitated by using rabbit idiotypic antibodies raised against the same purified allergen. The mouse anti-idiotypic antibodies recognized shrimp-specific human idiotypic antibodies of the IgE isotype from 18 of 20 individuals, and IgG antibodies from 14 of 20 shrimp-sensitive patients. Immunization of BALB/c mice with affinity-purified, allergen-specific anti-idiotypic antibodies induced anti-allergen IgE and IgG responses in the absence of the allergen. This paper thus presents evidence that anti-idiotypic antibodies raised against allergen-specific idiotypic antibodies may substitute for the original allergen in the induction of allergen-specific idiotypic antibodies. The demonstration of shared idiotopes on IgG and IgE antibodies in the sera of shrimp-sensitive patients supports the use of allergen-specific anti-idiotypic antibodies as surrogate allergens.
