Gastric Plication and Sleeve Gastrectomy in an Experimental Model of Obesity: New Insights into Weight Loss, Intake and Metabolic Results.

AIM: Laparoscopic gastric plication (LGP) is a bariatric surgical technique based on the anatomical principles of laparoscopic sleeve gastrectomy (LSG), but its effects on the metabolic profile are still uncertain. The aim of our study is to compare the changes in weight, metabolic parameters and gastric histology following intervention by gastric plication (GP) and sleeve gastrectomy (SG) in an experimental model of obesity. METHODS: To conduct the study, 32 8-week-old male Sprague-Dawley rats (Charles River®) were fattened by means of a cafeteria diet and randomly assigned to the following experimental groups: group 1: GP (n = 12); group 2: SG (n = 12) and group 3: sham (n = 8). RESULTS: Unlike the SG group, the GP group attained the weight of the sham group at the end of the experiment (week 16). The GP group continued to eat more cafeteria diet than the SG group. In addition, the SG group achieved better glycaemic control than the GP group. Significantly higher plasma ghrelin levels were observed at week 16 in the GP group than in the SG group (2.29 ± 0.5 vs 1.07 ± 0.4, p < 0.05), which also occurred for the glucagon plasmatic levels (62.71 ± 36.2 vs 24.63 ± 9.3, p < 0.05). CONCLUSIONS: GP is not as effective as SG and cannot be considered a metabolic surgery due to observed hormonal variations. The animals subjected to a GP continued to have a high appetite for the cafeteria diet unlike the animals submitted to an SG. Hormonal mechanisms possibly related to glucagon and ghrelin may be involved in this metabolic response.

Effect of genistein added to bull semen after thawing on pronuclear and sperm quality.

The aim of this research was to study the effect of different genistein treatments on bull sperm after thawing on pronuclear formation after in vitro fertilization (IVF) and on different sperm quality variables. Three experiments were performed. In Experiment 1, three treatments (Control, sperm incubation for 1h at 37 °C with or without genistein) and two sperm concentrations during IVF (1 or 3 × 10(6)sperm/mL) were evaluated to study the influence of genistein on pronuclear formation (PNF). Sperm incubation for 1h before IVF reduced PNF regardless of sperm concentration. However, after sperm incubation and with 3 × 10(6)sperm/mL in IVF, the genistein treatment group had greater fertilization rates than the untreated group. In Experiment 2, six treatments plus the control group were performed to study the effect of genistein (presence or not) and incubation conditions (30 min at 37 °C, 1h at 27 °C or at 37 °C) on PNF using 3 × 10(6)sperm/mL for IVF. When incubation time was reduced to 30 min, PNF rate from the genistein treatment group was no different from either the control group or in the group in which incubation occurred for 1h at 27 °C. In Experiment 3, the effect of several genistein treatments (control; genistein treatment for 30 min of incubation at 37 °C; genistein treatment for 1h of incubation at 27 °C) on sperm motility, viability and DNA fragmentation were evaluated. Genistein did not improve sperm motility and, depending on the experimental group or time, it either reduced or had no effect on sperm motility. Genistein treatment did not improve sperm viability after 5h of incubation. However, genistein treatment for 1h at 27 °C decreased sperm DNA fragmentation compared with the control group after 5h of sperm incubation. In conclusion, the treatment of bull sperm with genistein for 1h at 27 °C could decrease sperm DNA fragmentation, although PNF rate after IVF and sperm motility were reduced.

Prevalence of asthma and severity of allergic rhinitis comparing 2 perennial allergens: house dust mites and Parietaria judaica pollen.

BACKGROUND: Allergic rhinitis (AR) is an increasingly prevalent worldwide disease that has a considerable impact on quality of life and health care costs. Asthma and AR may be part of the same disease, with AR leading to an increased risk of asthma. OBJECTIVES: To assess the prevalence of asthma in patients with AR due to house dust mites (HDMs) or Parietaria judaica and analyze the characteristics of asthma and AR in each group. METHODS: Cross-sectional, multicenter study with recording of demographic and clinical characteristics. All patients had AR confirmed by symptoms and a positive skin prick test to HDMs or P judaica. They were classified according to the severity and frequency ofAR following the Allergic Rhinitis and its Impact on Asthma (ARIA) and modified ARIA criteria and according to the severity of asthma following the Global Initiative for Asthma criteria. RESULTS: We studied 395 patients (226 in the HDM group and 169 in the Pjudaica group) with a mean (SD) age of 43 (15.3) years. Using the modified ARIA criteria, we detected more severe and persistent AR in the P judaica group than in the HDM group (44.5% vs 24.8%, P < .001). Nevertheless, there were no statistically significant differences between the groups in terms of the severity or prevalence (50% in HDM vs 47.9% in P judaica, P = .685) of asthma. CONCLUSION: AR due to P judaica pollen, which behaves like a perennial allergen, is associated with the same prevalence of asthma and with more severe rhinitis than AR due to HDMs.

Prevalence of Asthma and Severity of Allergic Rhinitis Comparing 2 Perennial Allergens: House Dust Mites and Parietaria judaica Pollen

Antecedentes: La rinitis alérgica (RA) es una enfermedad de prevalencia creciente en todo el mundo, con un importante impacto en la calidad de vida, generando un elevado coste sanitario. La rinitis y el asma pueden ser consideradas como parte de una misma enfermedad y por tanto, la RA puede conducir a un incremento del riesgo de desarrollar asma. Objetivos: Evaluar la prevalencia de asma en pacientes con RA por ácaros del polvo doméstico (APD) y en pacientes con RA por Parietaria judaica y evaluar las características de la rinitis y del asma en cada grupo. Métodos: Estudio multicéntrico, transversal. Se registraron las características demográficas y clínicas de todos los pacientes. Todos los pacientes tenían RA confirmada por síntomas y pruebas positivas a APD o a Parietaria judaica. Los pacientes se clasificaron según la gravedad y la frecuencia de la rinitis siguiendo los criterios del ARIA y ARIA modificada y la gravedad del asma según los criterios de la GINA. Resultados: Se incluyeron un total de 395 pacientes, 226 en el grupo de APD y 169 en el grupo de la Parietaria judaica, con una media de edad de 43±15,3 años. La clasificación ARIA modificada nos permitió detectar que el grupo de Parietaria presentaba una rinitis más persistente y grave comparado con el grupo de APD (44,5% versus 24,8%, p<0,001). Sin embargo, no se obtuvieron diferencias estadísticamente significativas entre la gravedad y la prevalencia (50% en APD vs 47,9% en Parietaria, p=0,685) del asma en los dos grupos. Conclusiones: La RA por polen de Parietaria judaica, que se comporta como un alérgeno perenne, puede causar la misma prevalencia de asma y una rinitis más grave que APD (AU)

Beneficial effect of melatonin on blastocyst in vitro production from heat-stressed bovine oocytes.

Melatonin may play an important role in protecting gametes and embryos from the potential harmful effects of oxidative stress. In this study, we first examined two different heat stress (HS) treatments for in vitro oocyte maturation (Experiment 1: 38.5 vs 41.0°C, during the first 20 h; Experiment 2: 38.5 vs 41.5°C, during the entire period) on bovine oocyte maturation and embryo development. Second, we tested different melatonin concentrations added to the maturation and culture medium (Experiment 3: 0, 10(-12) , 10(-9) , 10(-4)  m; Experiment 4: 0, 10(-3)  m), both with and without HS (38.5 or 41.5°C, respectively). In Experiment 1, the HS treatment resulted in a lower maturation rate and number of cells/blastocyst (C/B) and a higher blastocyst rate than that in the control group. In Experiment 2, oocytes/embryos from heat-stressed oocytes (HSO) had a lower maturation, cleavage and blastocyst rates, as well as a lower C/B compared with the control. In Experiment 3, in HSO groups, 10(-4)  m melatonin resulted in an increased blastocyst rate compared with 0 m melatonin, with a similar blastocyst rate to the non-HSO without melatonin. Melatonin did not have any effect in embryos from non-HSO groups compared with the control. In Experiment 4, 10(-3)  m melatonin produced lower cleavage and blastocyst rates in HSO and lower blastocyst rate in non-HSO when compared to melatonin-untreated oocytes/embryos. In conclusion, 10(-4)  m melatonin was found to alleviate bovine oocytes from the harmful effects of HS.

Development and validation of a new Spanish instrument to measure health-related quality of life in patients with allergic rhinitis: the ESPRINT questionnaire.

OBJECTIVES: To develop and validate an instrument to measure health-related quality of life (HRQOL) specific to patients with allergic rhinitis (AR) and primarily for use in Spanish and Spanish-speaking populations. METHODS: An initial item pool was generated from literature review, focus groups with AR patients, and consultations with clinical experts. Item reduction was performed using clinimetric and psychometric approaches after administration of the item pool to 400 AR patients. The resulting instrument's internal consistency, test-retest (2-4 weeks) reliability, known groups and convergent validity, and sensitivity to change were tested in a longitudinal, observational, multicenter study in 210 AR patients who also completed the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ). RESULTS: The new questionnaire took a mean (SD) of 7.1 (5.4) minutes to answer. Floor and ceiling effects were less than 15% on all dimensions. Cronbach's alpha values and intraclass correlation coefficient values for six of the sevendimensions and the overall score exceeded 0.70. Statistically significant differences (P < 0.01) were observed on all ESPRINT-28 dimensions and the overall score between patients with mild (mean overall score 1.97, SD 0.99), moderate (mean overall score 2.78, SD 0.88), and severe AR (mean overall score 3.89, SD 0.87). Patients with persistent AR had worse scores (P < 0.05) on all dimensions than patients with intermittent AR. Correlations between the ESPRINT-28 and the RQLQ were generally as expected. Effect sizes for score changes between the two study visits ranged from 0.96 to 1.76 for individual dimensions and the overall score. CONCLUSIONS: This new, Spanish-developed instrument to measure HRQOL in AR patients has shown good reliability, validity, and sensitivity to change. It has also proved easy to use and administer.

Effectiveness of virosomal subunit influenza vaccine in preventing influenza-related illnesses and its social and economic consequences in children aged 3-14 years: a prospective cohort study.

To evaluate the effectiveness of a virosomal subunit influenza vaccine in preventing influenza-related illnesses and its social and economic consequences in children aged 3-14 years, a prospective cohort study was carried out during the 2004-2005 influenza season in 11 private pediatric clinics in the Barcelona metropolitan area. One dose of a virosomal subunit inactivated influenza vaccine (Inflexal V Berna) was given during September and October 2004 to healthy children aged 3-14 years attended in 5 of the 11 clinics. Who comprised the vaccinated cohort (n=966). The non-vaccinated cohort (n=985) was comprised of children attended in the other six clinics. Informed consent was obtained from all parents. The follow up was performed between 1 November 2004 and 31 March 2005. Using a self-administered questionnaire, information was collected from parents or guardians on any type of acute, febrile respiratory illness suffered by their children during the study period, including antibiotic use, and absence from school or work-loss of parents as a result of the illness. RT-PCR (influenza A+B+C) was carried out on pharyngeal and nasal samples obtained from children attended by pediatricians during this period in these clinics with the following symptoms: fever> or =38.5 degrees lasting at least 72h, cough or sore throat (influenza-like illness). Adjusted vaccination effectiveness was 58.6% (95% CI 49.2-66.3) in preventing acute febrile respiratory illnesses, 75.1% (95% CI 61.0-84.1) in preventing cases of influenza-like illnesses and 88.4% (95% CI 49.2-97.3) in preventing laboratory-confirmed cases of influenza A. The adjusted vaccination effectiveness in reducing antibiotic use (18.6%, 95% CI -4.2 to 3.64), absence from school (57.8%, 95% CI 47.9-65.9) and work-loss of parents (33.3%, 95% CI 8.9-51.2) in children affected by an acute febrile respiratory illness was somewhat lower. Vaccination of children aged 3-14 years in pediatric practices with one dose of virosomal subunit inactivated influenza vaccine has the potential to considerably reduce the health and social burdens caused by influenza-related illnesses.

[Bronchial asthma in the 2d and 3d year of life]. / Asma bronquial en el segundo y tercer año de le vida.

In studying age of onset in our cases of extrinsic asthma, we found that symptomatology occurred in 50% of our patients before the age of 3, and in 45.2% between the first and third year of life. We are therefore concerned about children coming to our service after a long period of illness, since difficulty of recuperation correlates with the duration of asthma. When the onset of asthma is between the first and third years, the child is not yet familiar with his own body's function, and learns how to live as an asthmatic with decreased lung capacity in the intercritic period. As noted by Shepherd, the retention of mucus in a child's lungs will impair the respiratory function more than it does in the adult, since the lesion of an immature structure may hinder its normal development. It is therefore important at this age to maintain respiratory function. 242 children aged between 1 and 3 were studied, who suffered from obstructive respiratory syndromes whose etiology was determined by clinical history and immunoallergic parameters, both "in vivo" and "in vitro". The correlation between the RAST and skin test values by planimetry was also studied. 4 groups were distinguished according to the Foucard score: Group I: consisted of children with a clinical history suggestive of extrinsic allergic asthma due to house dust/mites, with positive skin tests and RAST positive 3-4. Group IIa: also suggestive of extrinsic allergic asthma, with positive clinical history, positive skin test and RAST O. Group IIb: with a positive clinical history, positive skin test and RAST 1-2. Group III: consisted of children with obstructive bronchitis, and uncertain clinical history, negative skin and inhalant tests and RAST O. Group IV: consisted of children with extrinsic asthma due to moulds, with a suggestive clinical history, positive skin tests and RAST 1-2-3-4. Diagnostic methods and therapy in the different groups are discussed. There is a high incidence of onset between the 2nd and 3rd year of age (45%). In the pediatric allergic service the incidence of onset in this age group is only 7.8%. Early diagnosis is essential to avoid damage to lung function in the intercritic period. Difficulty of diagnosis: in the 2nd year we found 38.4% positive and 15.5% suggestive results, totalling 53.9%; and in the 3rd year we found 45.7% positive and 6.2% suggestive results, totalling 51.9%, giving us a more than 50% possibility of extrinsic allergic asthma as the diagnosis.
