RESUMEN

OBJECTIVES: Many factors are associated with the increase in total and central body adiposity in children, especially eating habits. This has led to an increasing number of studies analysing food patterns, which consider the synergistic effect of food and nutrient intake on the nutritional status. The objective of this study was to identify the dietary patterns of children aged 4-7 years and associate these with different indicators of total and central body adiposity. STUDY DESIGN: Cross-sectional study METHODS: The study consisted of 403 children from a retrospective cohort in Minas Geraes, Brazil. Four indicators of body adiposity were evaluated: body mass index (BMI), waist-to-height ratio (WHtR) and percentages of total and central body fat (assessed by dual-energy X-ray absorptiometry). The dietary habits of the children were evaluated by identifying the dietary patterns using principal component analysis. The adjustment predictor variables were related to the socio-economic characteristics, lifestyle and duration of exclusive breastfeeding. Food patterns were identified by factor analysis. Linear regression was used to estimate the regression coefficient and the confidence interval, considering statistical significance of α = 5%. RESULTS: Five dietary patterns were identified, which explained 42.3% of the data variance: 'Traditional', 'Unhealthy', 'Milk and chocolate', 'Snack' and 'Healthy'. The multiple linear regression model showed that a greater adherence to the 'Traditional' and 'Unhealthy' patterns was related to higher BMI, WHtR, and total and central body adiposity. CONCLUSION: Children with a higher intake of food from the 'Traditional' and 'Unhealthy' patterns showed an increase in total and central body adiposity.

RESUMEN

PurposeTo report the visual and anatomic outcomes in eyes with macular oedema (MO) secondary to central retinal vein occlusion (CRVO) that were switched from either intravitreal bevacizumab or ranibizumab to intravitreal aflibercept.MethodsTwo-center retrospective chart review. Eyes with MO secondary to CRVO that received a minimum of three intravitreal injections of bevacizumab or ranibizumab and were switched to intravitreal aflibercept for persistent or recurrent MO not responding to either bevacizumab and/or ranibizumab.ResultsIn all 42 eyes of 42 patients were included in the study. The median visual acuity before the switch was 20/126, 1 month after the first injection of aflibercept 20/89 (P=0.0191), and at the end of the follow-up 20/100 (P=0.2724). The median CRT before the switch was 536 µm, 1 month after the first injection of aflibercept 293.5 µm (P=0.0038), and at the end of the follow-up 279 µm (P=0.0013 compared to before the switch). The median number of weeks between injections before the switch was 5.6 and after the switch was 7.6 (P<0.0001).ConclusionConverting eyes with refractory MO due to CRVO to aflibercept can result in stabilization of the vision, improved macular anatomy, and extension of the injection interval.

RESUMEN

PURPOSE: To examine the accuracy and predictive ability of B-scan ultrasonography in the post-repair assessment of an open globe injury. METHODS: In all, 965 open globe injuries treated at the Massachusetts Eye and Ear Infirmary between 1 January 2000 and 1 June 2010 were retrospectively reviewed. A total of 427 ultrasound reports on 210 patients were analyzed. Ultrasound reports were examined for the following characteristics: vitreous hemorrhage, vitreous tag, retinal tear, RD (including subcategories total RD, partial RD, closed funnel RD, open funnel RD, and chronic RD), vitreous traction, vitreous debris, serous choroidal detachment, hemorrhagic choroidal detachment, kissing choroidal detachment, dislocated crystalline lens, dislocated intraocular lens (IOL), disrupted crystalline lens, intraocular foreign body (IOFB), intraocular air, irregular posterior globe contour, disorganized posterior intraocular contents, posterior vitreous detachment, choroidal vs retinal detachment, vitreal membranes, and choroidal thickening. The main outcome measure was visual outcome at final follow-up. RESULTS: Among 427 B-scan reports, there were a total of 57 retinal detachments, 19 retinal tears, 18 vitreous traction, 59 serous choroidal detachments, 47 hemorrhagic choroidal detachments, and 10 kissing choroidal detachments. Of patients with multiple studies, 26% developed retinal detachments or retinal tears on subsequent scans. Ultrasound had 100% positive predictive value for diagnosing retinal detachment and IOFB. The diagnoses of retinal detachment, disorganized posterior contents, hemorrhagic choroidal detachment, kissing choroidal detachment, and irregular posterior contour were associated with worse visual acuity at final follow-up. Disorganized posterior contents correlated with particularly poor outcomes. CONCLUSIONS: B-scan ultrasonography is a proven, cost-effective imaging modality in the management of an open globe injury. This tool can offer both diagnostic and prognostic information, useful for both surgical planning and further medical management.

RESUMEN

OBJECTIVES: Breast-conserving therapy (BCT), including postoperative whole breast irradiation (WBI), is generally accepted as the treatment of choice for most patients with early-stage breast cancer. The question whether WBI is mandatory in all patients remains one of the most controversial issues in BCT. To answer this question, a randomized, prospective, multicentre study was launched in January 2001. Primary endpoints of the study were to assess the cumulative incidence of in-breast-recurrences (IBR) and overall survival (OAS) after conservative surgery (BCS) with or without WBI. METHODS: From January 2001 until December 2005, 749 patients with unifocal infiltrating breast cancer up to 25 mm, 0-3 positive axillary lymph nodes, no extensive intraductal component or lymphvascular invasion from 11 centres in Italy, were randomly assigned to BCS+WBI (arm 1:373 patients) or BCS alone (arm 2:376 patients). Treatment arms were well balanced in terms of baseline characteristics. Systemic adjuvant therapy was administered according to the institutional policies. Kaplan-Meier method was used for survival analysis and log-rank test to evaluate the difference between the two arms. RESULTS (Last analysis 31.12.2012): After median follow-up of 108 months, 12 (3.4%) IBR were observed in arm 1 and 16 (4.4%) in arm 2. OAS was 81.4% in arm 1 and 83.7% in arm 2. There was no statistically significant difference regarding IBR and death in the two treatment groups. CONCLUSIONS: These data are promising and suggest that WBI after BCS can be omitted in selected patients with early stage breast cancer without exposing them to an increased risk of local recurrence and death. Longer follow-up is needed to further consolidate these results.

RESUMEN

Bowel obstruction resulting from colorectal and ovarian cancer is a serious and distressing complication of these malignancies. This may be caused by diffuse peritoneal carcinomatosis, bulky masses filling the pelvis and abdomen or postoperative adhesions, and should be carefully worked out by pre-operative imaging. We report the case of a small bowel obstruction and intestinal ischemia caused by a bulky (20x40 cm in diameter) cystic ovarian neoplasm that was found to be a stage IA G2 cystadenocarcinoma, successfully managed by uterus-sparing surgery.

RESUMEN

PURPOSE: We investigated in a single institution series of 124 women with operable breast cancer whether tumor clinicopathological features could predict the 70-gene signature (Mammaprint, MP) results, and whether MP results could help to make decisions for the use of chemotherapy (CT) in patients (pts) with ER positive breast cancer beyond recommendations of international guidelines. RESULTS: Among the 68 ER/PgR positive, HER2 negative tumors, Ki-67 ≥ 20% was the only significant predictor of a high risk-MP among standard clinicopathological features. In candidates for endocrine therapy with undetermined benefit from CT according to international guidelines, MP results would have led to different treatment decisions in 13/46 (28%) and in 20/68 (29%) pts according to NCCN and St. Gallen recommendations, respectively. CONCLUSIONS: Ki-67 independently predicted high risk-MP in ER/PgR positive, HER2 negative tumors. MP results would have led to discordant treatment recommendations in about 30% of cases, generally increasing indication rate for CT. The results of large randomized trials are warranted in order to understand whether we should rely on multigene assays rather than on standard clinicopathological features for treatment decisions.

RESUMEN

The aim of this study was to report epidemiologic data and results of arthroscopic treatment of glenohumeral instability in soccer goalkeepers. We included 12 soccer goalkeepers with a mean age of 28.9 years (range 18-45 years) with acute or recurrent traumatic anterior instability who underwent an arthroscopic anatomic capsulolabral repair with bone anchors. Patients who underwent surgery within 4 weeks of the first episode of dislocation were classified as acute instability. The results were evaluated using the Rowe Scale and analyzed according to stability, range of motion and function. The mean follow-up was 3.8 years. The most common mechanism of injury (90% of the cases) was abduction, external rotation and extension. Associated injuries were present in 57.2% of recurrent cases and 20% of acute cases (p<0.293). Excellent or good results were observed in 80% of the cases of acute instability and in 57.2% of cases in the group with recurrent instability (p<0.586). From a total of 12 soccer goalkeepers who underwent the arthroscopic capsulolabral repair, good or excellent results were obtained in 66.6% of cases of glenohumeral instability. Surgical arthroscopic repair was possible in all cases of acute or recurrent instability based on well-established inclusion criteria, i. e., with well-defined exclusion criteria, such as HAGL lesion and significant glenohumeral bone loss, the arthroscopic capsulolabral repair can be carried out in soccer goalkeepers.

RESUMEN

This cross-sectional prospective study assessed follicular-fluid anti-Müllerian hormone (AMH) concentrations in infertile patients with mild/minimal endometriosis during natural IVF. Thirty-two women participated in the study. Patients were divided into two groups: tubal obstruction without endometriosis (control group) and minimal/mild endometriosis (study group). All patients underwent laparoscopy for assessment of infertility; at the same time, any foci of endometriosis found were cauterized. AMH concentration was measured in the follicular fluid of a single follicle when it achieved pre-ovulatory maturation by ultrasensitive enzyme-linked immunosorbent assay. Likewise, AMH, FSH and inhibin B content in serum was also measured. Age (30 ± 1.3 and 32 ± 0.8 years) and body mass index (22 ± 0.6 and 22 ± 0.5 kg/m(2)), day-3 antral follicle count (11.3 ± 1.7 and 10.7 ± 1.5), serum FSH concentrations (5.4 ± 0.6 and 5.0 ± 0.3 IU/ml) and follicular-fluid AMH concentrations (1.8 ± 0.3 and 1.5 ± 0.1 ng/ml, study and control group, respectively; mean difference 0.33, 95% CI -0.21 to 0.88) were similar in both groups. This study shows that infertile patients with minimal/mild endometriosis have a similar concentration of AMH in the follicular fluid after natural IVF as compared with control subjects.

RESUMEN

Breast conserving therapy (BCT) including postoperative irradiation of the remaining breast tissue is generally accepted as the best treatment for the majority of patients with early-stage breast cancer. The question is whether there is a necessity for irradiating all patients. Between 2001 and 2005, 749 women aged 55-75 years with infiltrating breast carcinoma were randomly assigned to breast conservative surgery, with or without radiotherapy (RT), to evaluate the incidence of in-breast recurrence (IBR). After 5 years of median follow-up, the cumulative incidence of IBR was 2.5% in the surgery-only arm and 0.7% in the surgery plus RT arm. There are no differences in terms of overall survival and distant disease-free survival. The preliminary evaluation suggests that breast irradiation after conservative surgery can be avoided without exposing these patients to an increased risk of distant-disease recurrence. Prolonged follow-up will further clarify the possible risks and late sequelae potentially induced by breast RT.

RESUMEN

Defining the mitochondrial proteome is a prerequisite for fully understanding the organelles function as well as mechanisms underlying mitochondrial pathology. The core functions of mitochondria include oxidative phosphorylation, amino acid metabolism, fatty acid oxidation, and ion homeostasis. In addition to these well-known functions, many crucial properties in cell signaling, cell differentiation and cell death are only now being elucidated, and with them the proteins involved. With the wealth of information arriving from single protein studies and sophisticated genome-wide approaches, MitoP2 was designed and is maintained to consolidate knowledge on mitochondrial proteins in one comprehensive database, thus making all pertinent data readily accessible (http://www.mitop2.de). Although the identification of the human mitochondrial proteome is ultimately the prime objective, integration of other species includes Saccharomyces cerevisiae, mouse, Arabidopsis thaliana, and Neurospora crassa so orthology between these species can be interrogated. Data from genome-wide studies can be individually retrieved and are also processed by a support vector machine (SVM) to generate a score that indicates the likelihood of a candidate protein having a mitochondrial location. Manually validated proteins constitute the reference set of the database that contains over 590 yeast, 920 human, and 1020 mouse entries, and that is used for benchmarking the SVM score. Multiple search options allow for the interrogation of the reference set, candidates, disease related proteins, chromosome locations as well as availability of mouse models. Taken together, MitoP2 is a valuable tool for basic scientists, geneticists, and clinicians who are investigating mitochondrial physiology and dysfunction.

RESUMEN

Even if the overall number of cancer is increasing, the mortality has started to decrease in the Western World. The role of early detection in this decrease is a matter of debate. To assess its impact on mortality it is important to distinguish between diagnosis of cancer in symptomatic patients, and early detection in asymptomatic individuals who may self-refer or who may be offered ad hoc or systematic screening. The policies for early detection and screening vary greatly between European countries, despite many similarities in their cancer burden, and this partly reflects the uncertainties surrounding asymptomatic testing for cancer. A Task Force of European expert, held in Azzate (VA), Italy, established to address these issues, acknowledged the need for more research in the field of individual risk assessment since general statistics are more and more perceived as inadequate to design personal early detection plans. The group also recognised that combinations of early detection and screening will enforce the effectiveness of new treatments in curbing mortality curves, although policies will vary with different cancers.

RESUMEN

DNA repair polymorphisms may represent susceptibility factors affecting DNA integrity, and possibly cancer risk, in human population. In order to elucidate the influence of a few widely studied DNA repair polymorphisms on individual levels of DNA damage and their possible interaction with lifestyle and environmental exposures, 171 subjects from a well-characterized human population enrolled in a previous study on genetic effects of air pollution were genotyped for the XRCC1 Arg280His and Arg399Glu, XRCC3 Thr241Met and ERCC2 Lys751Gln polymorphisms. The association between DNA repair genotype, alone or in combination with metabolic genotype, on the levels of SCE, micronuclei and tail moment values in peripheral lymphocytes was evaluated. A significant influence of the ERCC2 genotype on SCE frequency was observed. Subjects with ERCC2 751 Gln/Gln genotype had significantly higher risk of high (above the median) SCE/cell with respect to Lys/Lys referents (OR 4.55, 95% CI 1.48-13.99). A non-significantly elevated OR was also observed in Gln/Lys heterozygotes, suggesting a gene dosage effect. When subjects were categorized by smoking habits and professional exposure, the variant ERCC2 751 Gln/Gln genotype was associated with elevated SCE rates in non-smokers and in exposed subjects, but not in smokers. The results of this study support the hypothesis that some DNA repair polymorphisms exert a modifying effect on individual levels of DNA damage in healthy subjects, possibly also modulating cancer risk.

RESUMEN

The MitoP2 database (http://www.mitop.de) integrates information on mitochondrial proteins, their molecular functions and associated diseases. The central database features are manually annotated reference proteins localized or functionally associated with mitochondria supplied for yeast, human and mouse. MitoP2 enables (i) the identification of putative orthologous proteins between these species to study evolutionarily conserved functions and pathways; (ii) the integration of data from systematic genome-wide studies such as proteomics and deletion phenotype screening; (iii) the prediction of novel mitochondrial proteins using data integration and the assignment of evidence scores; and (iv) systematic searches that aim to find the genes that underlie common and rare mitochondrial diseases. The data and analysis files are referenced to data sources in PubMed and other online databases and can be easily downloaded. MitoP2 users can explore the relationship between mitochondrial dysfunctions and disease and utilize this information to conduct systems biology approaches on mitochondria.

RESUMEN

BACKGROUND: Tears of the rotator cuff tendons, which surround the joints of the shoulder, are one of the most common causes of pain and disability in the upper extremity. OBJECTIVES: To review the efficacy and safety of common interventions for tears of the rotator cuff in adults. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group specialised trail register (July 2002), the Cochrane Controlled Trials Register (The Cochrane Library issue 2, 2002), MEDLINE (1966 to December 2001), EMBASE (1974 to December 2001), Biological Abstracts (1980 to December 2001), LILACS (1982 to December 2001), CINAHL (November 1982 to December 2001), Science Citation Index and reference lists of articles. We also contacted authors and handsearched conference proceedings focusing on shoulder conditions. SELECTION CRITERIA: Randomised or quasi-randomised clinical trials involving tears of the rotator cuff were the focus of this review. All trials involving conservative interventions or surgery were included (non-steroidal anti-inflammatory drugs, intra-articular or subacromial glucocorticosteroid injection, oral glucocorticosteroid treatment, physiotherapy, and open or arthroscopic surgery). DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed suitability for inclusion, methodological quality and extracted data. Dichotomous data were presented as relative risks (RR) and 95% confidence intervals (CI), using the fixed effects model. MAIN RESULTS: Eight trials involving 455 people were included and 393 patients analysed. Trials were grouped in eight categories of conservative or surgical treatment. The median quality score of all trials combined was 16 out of a possible 24 points, with a range of 12-18. In general, included trials differed on diagnostic criteria for rotator cuff tear, there was no uniformity in reported outcome measures, and data which could be summarised were rarely reported. Only results from two studies comparing open repair to arthroscopic debridement could be pooled. There is weak evidence for the superiority of open repair of rotator cuff tears compared with arthroscopic debridement. REVIEWER'S CONCLUSIONS: There is little evidence to support or refute the efficacy of common interventions for tears of rotator cuff in adults. As well as the need for further well designed clinical trials, uniform methods of defining interventions for rotator cuff tears and validated outcome measures are also essential.

RESUMEN

The aim of the MitoP2 database (http://ihg.gsf.de/mitop2) is to provide a comprehensive list of mitochondrial proteins of yeast and man. Based on the current literature we created an annotated reference set of yeast and human proteins. In addition, data sets relevant to the study of the mitochondrial proteome are integrated and accessible via search tools and links. They include computational predictions of signalling sequences, and summarize results from proteome mapping, mutant screening, expression profiling, protein-protein interaction and cellular sublocalization studies. For each individual approach, specificity and sensitivity for allocating mitochondrial proteins was calculated. By providing the evidence for mitochondrial candidate proteins the MitoP2 database lends itself to the genetic characterization of human mitochondriopathies.

RESUMEN

Gene-environment interactions play an important role in folate metabolism, with a potential impact on human health. Deficiencies in the uptake of key micronutrients and variant genotypes can affect the folic acid cycle, modulating methyl group transfer in key processes and leading to increased cancer risk and Down syndrome incidence. So far, the significance of folate status and metabolic genotypes on baseline levels of DNA damage in normal individuals has not been fully elucidated. In this study, the possible modulation of SCE, micronuclei and tail moment values in peripheral lymphocytes by plasma levels of folic acid, homocysteine and vitamin B12, and by the methylenetetrahydrofolate reductase (MTHFR) C677T and methionine synthase reductase (MTRR) A66G polymorphisms was investigated in 191 healthy subjects. The results obtained show a highly significant (P = 0.001) positive association between plasma levels of vitamin B12 and frequencies of both SCE and high frequency cells (HFC, above 90 degrees percentile) in smokers. No significant effect was observed in non-smokers. Moreover, after correction for age, gender and GSTM1 genotype, a significant association (P = 0.026) between the MTRR 66GG variant genotype and higher micronucleus rates was observed. Tail moment values were not affected by any of the independent variables considered. Overall, the results obtained suggest that both folate status and relevant metabolic genotype can influence background levels of DNA damage in normal subjects. The significant association observed in smokers between plasma vitamin B12 and SCE frequencies may highlight the effect of methylation status on DNA damage and repair, although the role of other, unidentified dietary factors cannot be ruled out. At the same time, micronucleus data indicate that the MTRR 66GG variant may represent another individual trait of relative genomic instability, thus supporting epidemiological data on increased risk of Down syndrome conception in MTRR 66GG subjects.

RESUMEN

The malformative syndrome of double vagina in association with uterus didelphus and kidney agenesis is a rare condition, often asymptomatic: if this condition is accompanied by imperforated obstructed hemivagina, the clinical manifestations depend on the presence of hematocolpos. MRI plays an important role for diagnosis because it allows to characterize the nature of the lesion and to evaluate the anatomical details of the uterine malformation. The authors describe this complex genital malformation and discuss the main US and MRI features.

RESUMEN

The solid residue generated from the sewage treatment receives the denomination of sewage sludge, being also called biosolid. The present work compared the effect of 3 levels of fertilization (sewer sludge, mineral fertilization and proof) in the recovery of areas with 2 levels of soil degradation simulation (removal of 15 cm and 30 cm of soil), plus a proof. In the parcels destined for the biosolid, 40 dry t./ha of aerobic limy stabilized 30% had been used. The content of Ca+Mg, K, V% and CTC in the parcels that received biosolids had its value increased by 11.7%, 28.0%, 8.3% and 6.0% respectively, when compared with the values of the proof at the end of the maize culture. The contents of phosphorus were statistically higher for the Tukey test at 5% of probability in the treatment with biosolid, verifying also the trend of accumulation of phosphorus in the parcels, with the simulated level of degradation of 30 cm. There was a significant increase in carbon content due to the application of biosolids. The production of dry substance was still evaluated, where the biggest productions had been statistically verified in the treatments, being slightly influenced by the different levels of soil degradation, evidencing the great capacity of silt as recovery agent.
