RESUMEN
Background Acoustic radiation force impulse (ARFI) is a non-invasive alternative to a liver biopsy for the evaluation of liver fibrosis (LF). Purpose To investigate the potential usefulness of acoustic radiation force impulse ARFI for detecting LF in overweight and obese children Material and Methods A cross-sectional study was conducted in 148 schoolchildren. A diagnosis of non-alcoholic fatty liver disease (NAFLD) and LF was based on ultrasound (US) and ARFI shear wave velocity (SWV). Results The laboratory parameters were normal in all the children. NAFLD was observed in 50 children (33.8%). The median SWV was 1.18 ± 0.28 m/s. Differences between ARFI categories and hepatic steatosis grades were observed (χ2 = 43.38, P = 0.0005). No fibrosis or insignificant fibrosis (SWV ≤ 1.60 m/s) was detected in 137 children (92.5%), and significant fibrosis (SWV > 1.60 m/s) in 11 children (7.5%), nine of whom had normal US or mild steatosis. Conclusion The present study is the first to evaluate the utility of the ARFI technique for detecting LF in overweight and obese children. The results of the study suggest that children with normal laboratory parameters such as normal liver ultrasound or mild steatosis may present with significant LF.

OBJECTIVE: The aim of this study was to determine the possible relationship between the Sp1 polymorphism of gene COL1A1 and bone metabolism disorder in individuals with epilepsy. METHODS: To this end, we carried out an observational cross-sectional study on 64 patients in monotherapy with an antiepileptic drug. The patients were classified on the basis of the presence of the 's' allele of the COL1A1 Sp1 polymorphism. RESULTS: In the patients with SS, the standardized bone mineral density (sBMD) in the left femoral neck was 1024.9±206.1 mg/cm, whereas in the patients with Ss or ss, the density was significantly lower, 917±141.4 mg/cm (P=0.027), as was the femoral t-score (0.72±1.67 vs. -0.29±1.15, P=0.01). The values in the lumbar spine were equally greater in those with SS: 1219.1±236.3 versus 1090.5±142.7 mg/cm for the sBMD (P=0.018) and 0.67±1.98 versus -0.34±1.16 for the lumbar t-score (P=0.023). The bone biomarkers showed no significant differences nor did the 25-OH vitamin D and parathormone values. In the patient group treated with valproic acid (VPA), the densitometric values were significantly lower in the Ss or ss patients compared with SS homozygotes: 887.1±142.6 versus 1120.6±198.2 mg/cm for femoral sBMD (P=0.02), 990±98.1 versus 1417±251.2 mg/cm for lumbar sBMD (P=0.001). Of the patients who were carriers of the 's' allele and who were treated with VPA, 86% achieved osteopenia values. CONCLUSION: In our study, the presence of the 's' allele of the COL1A1 Sp1 polymorphism in individuals with epilepsy was related to lower bone BMD (lumbar and femoral). This relationship seemed to be further apparent in the patients undergoing treatment with VPA.

BACKGROUND AND OBJECTIVES: Postoperative seroma after axillary lymphadenectomy leads to an increased use of resources and an impaired quality of life of patients. This randomized clinical trial was designed to assess the value of a hemostatic and sealing agent for decreasing seroma occurrence after axillary lymphadenectomy. METHODS: A prospective, randomized, blind study was conducted on 91 axillary lymphadenectomies distributed into a control group (n = 47) and a test group in which a collagen sponge coated with human coagulation factors was used (n = 44). Primary end-points were number of days before removal of axillary drainage, axillary drainage output, and occurrence of seroma, wound infection, haematoma, or wound dehiscence, within 8 weeks of surgery. Bivariate and multivariate analyses on seroma occurrence were performed. RESULTS: Seroma occurred in 29 patients (31.86%). A significant direct relationship (P = 0.002) was only noted between use of the hemostatic and sealing agent and nonoccurrence of seroma. In the multivariate study, the only variable found to be significantly related to seroma occurrence was use of the above agent (P = 0.046; odds ratio: 3.365 [95%CI: 1.024-11.060]). CONCLUSIONS: Use of a collagen sponge coated with human coagulation factors following axillary lymphadenectomy was associated to a lower incidence of postoperative seroma. J. Surg.

BACKGROUND: To determine the toxicity of aqueous dilutions of a universal self-priming dental adhesive (DA) and comparing these with those elicited by exposure to ionizing radiation (IR), Zoledronic acid (Z) treatment and the synergic effects of the combined treatment with IR+Z. MATERIAL AND METHODS: The genotoxic effect of DA was determined by the increase in the frequency of micronuclei in cytokinesis-blocked in cultured human lymphocytes before and after exposure to 2Gy of X-rays. The cytotoxic effect was studied by using the MTT cell viability test in normal prostate cell lines (PNT2) after exposure to different X-ray doses (0Gy-20Gy). The cell lines divided into different groups and treated with different test substances: DA in presence of O2, DA in absence of O2, Z-treated and control. RESULTS: An in vitro dose-dependent and time-dependent cytotoxic effect of DA, Z and IR on PNT2 cells (p>0.001) was demonstrated. DA without-O2, following the recommendations of manufacturers, had a more pronounced effect of increasing cell death than DA with-O2 (p<0.001). In the genotoxicity assay, DA at 25% of its original concentration significantly increased chromosome damage (p<0.001). The samples studied were found to be toxic, and the samples photo-polymerized in absence of O2 showed a bigger cytotoxic effect comparable to the additive toxic effect showed by the combined treatment of IR+Z. CONCLUSIONS: Additional effort should be carried out to develop adhesives, which would reduce the release of hazardous substances; since toxic effects are similar to that reported by other agents whose clinical use is controlled by the health authorities.

BACKGROUND: Galactography is the technique of choice for investigating pathological nipple discharge. However, there is no standardized interpretation system for this procedure. PURPOSE: To evaluate radiological and histological correlation using a Galactogram Imaging Classification System (GICS). MATERIAL AND METHODS: We retrospectively studied all galactograms obtained in 62 women with pathological nipple discharge who subsequently had biopsy at our institution between 1999 and 2007. The GICS proposes five categories for galactographic findings: GICS 1: negative; GICS 2: benign; GICS 3: probably benign; GICS 4: suspect for malignancy; GICS 5: highly suspect for malignancy. RESULTS: The galactographic findings were classified as follows: GICS 2: 25.8% (16/62); GICS 3: 30.6% (19/62); GICS 4: 25.8% (16/62); and GICS 5: 17.7% (11/62). A good correlation was observed between histological diagnosis and GICS categories (P < 0.05). All the cases diagnosed with carcinoma (n = 11) were classified in GICS category 5. CONCLUSION: The present study shows a good correlation between GICS categories and histological diagnosis.

PURPOSE: To compare examination adequacy and patient discomfort during retrograde urethrography (RUG) performed by using the conventional balloon method versus those of RUG and voiding cystourethrography (VCUG) performed with the clamp method of using drip infusion for the administration of contrast material. MATERIALS AND METHODS: This prospective study was approved by the institutional review board; written informed consent was obtained from all patients. Eighty men (mean age, 64.3 years +/- 16 [standard deviation]; range, 18-85 years) suspected of having urethral stenosis were randomly distributed into two groups for urethrography: a control group (n = 36) and a clamp group (n = 44). In 11 of the 36 patients in the control group, the conventional balloon method could not be used, so these patients were transferred to the clamp group. Drip infusion was used to administer contrast material for RUG, and, except in cases where a suprapubic catheter was used (n = 8), for VCUG. The pain levels reported by patients were recorded by using a verbal descriptor scale (VDS) and a visual analogue scale (VAS). RESULTS: In the control group, RUG was successfully performed in 69% of patients (25 of 36), and mean pain levels recorded on inflation of the balloon were distressing according to the VDS and 4.8 +/- 1.4 (range, 2.3-7.5) according to the VAS. In the clamp group, RUG was successfully performed in all cases; in 69% of patients in this group (38 of 55), the pain level recorded at external compression was no pain according to the VDS and 0 according to the VAS, while mean values in the remaining 31% of patients (17 of 55) were mild pain on the VDS and 0.6 +/- 0.3 (range, 0.3-1.2) on the VAS. Bladder filling for VCUG was achieved with drip infusion in 96% of patients (69 of 72) in an average time of 11 minutes. CONCLUSION: The conventional balloon method of performing RUG is painful and, in some cases, not effective. The clamp method is a simple, well-tolerated procedure that allowed diagnostic evaluation in all cases. Drip infusion enables RUG and VCUG to be performed without the need for syringes or bladder catheters, thus increasing patient comfort.

BACKGROUND: The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life. OBJECTIVES: The aim of this project is to determine, assess and identify the real impact of breastfeeding support networks in Murcia (Spain). METHODS: After searching unsuccessfully for a validated questionnaire, a specific one was developed and validated for measuring the impact of formal and informal support networks through five dimensions: satisfaction, consultation, experience, problems and support. The questionnaire was provided to 500 mothers with experience in breastfeeding, who brought their children to baby paediatricians between 2 June and 27 November 2014. Upon completion of the survey and fieldwork, a detailed statistical analysis was conducted. RESULTS: The degree of satisfaction perceived by the users of the services of support breastfeeding networks is remarkable. In addition, mothers who clarified their doubts and discussed their problems with health professionals and/or breastfeeding support networks were more likely to breastfeed for a longer duration compared to those who did not (p=0.005). Furthermore, mothers who sought support in breastfeeding are more likely to breastfeed for more than 6 months (p<0.0005). CONCLUSION: Based on this information, we conclude that breastfeeding support networks have a positive influence in the duration of a women's decision to breastfeed.

BACKGROUND: overweight and obesity have been increasing, and university students are an important target for prevention programs. Previous studies have reported differences in the diagnosis between different anthropometric methods, so some students can be misclassified depending on the method used. OBJECTIVE: to evaluate the efficacy of different anthropometric methods to detect those university students in a probable status of overweight, including a comparison with a new proposed method, the normalized weight-adjusted index (NWAI). METHODS: different anthropometric methods (waist circumference, waist-hip ratio, waist-height ratio, body mass index, conicity index, bioimpedance and Brozek, Siri and Heath-Carter equations) were calculated for 505 university students. By k-means cluster analysis, students with higher values according to variables involved in overweight were identified. Parameters of accuracy were calculated by operating characteristic curves. RESULTS: NWAI showed significant correlations with the most used methods. Prevalence of students with body fat excess varied from 5.9% to 48.4% for women and from 8.5% to 49.0% for men depending of the method employed, being demonstrated a great variability between the different methodologies. Body mass index for women and waist circumference for men resulted to be the most accurate methods to detect a probable situation of excess of body fat or cardiovascular risk associated. NWAI resulted also a good alternative for overweight classification. CONCLUSIONS: differences between anthropometric methods for overweight and cardiovascular disease risk classification were confirmed. Classical cut-off point may misdiagnose overweight or health risk in Spanish university students depending of the method employed.

Gross Motor Function Classification System has discriminative purposes but does not assess short-term therapy goals. Locomotion Stages (LS) classify postural body functions and independent activity components. Assessing the relation between Gross Motor Function Classification System level and Locomotion Stages will make us understand if clinical assessment can explain and predict motor environmental performance in cerebral palsy. A total of 462 children were assessed with both scales. High reliability and strong negative correlation (-0.908) for Gross Motor Function Classification System and Locomotion Stages at any age was found. Sensitivity was 83%, and specificity and positive predictive value were 100% within the same age range. Regression analysis showed detailed probabilities for the realization of the Gross Motor Function Classification System depending on the Locomotion Stages and the age group. Postural body function measure with Locomotion Stages is reliable, sensitive, and specific for gross motor function and able to predict environmental performance.

OBJECTIVE: to understand the episiotomy rate and its relationship with various clinical variables. METHOD: a descriptive, cross-sectional, analytic study of 12,093 births in a tertiary hospital. VARIABLES: Parity, gestational age, start of labor, use of epidural analgesia, oxytocin usage, position during fetal explusion, weight of neonate, and completion of birth. The analysis was performed with SPSS 19.0. RESULTS: the global percentage of episiotomies was 50%. The clinical variables that presented a significant association were primiparity (RR=2.98), gestational age >41 weeks (RR=1.2), augmented or induced labor (RR=1.33), epidural analgesia use (RR=1,95), oxytocin use (RR=1.58), lithotomy position during fetal expulsion (RR=6.4), and instrumentation (RR=1.84). Furthermore, maternal age ≥35 years (RR=0.85) and neonatal weight <2500 g (RR=0.8) were associated with a lower incidence of episiotomy. CONCLUSIONS: episiotomy is dependent on obstetric interventions performed during labor. If we wish to reduce the episiotomy rate, it will be necessary to bear in mind these risk factors when establishing policies for reducing this procedure.

OBJECTIVES: To describe the differences in obstetrical results and women's childbirth satisfaction across 2 different models of maternity care (biomedical model and humanised birth). SETTING: 2 university hospitals in south-eastern Spain from April to October 2013. DESIGN: A correlational descriptive study. PARTICIPANTS: A convenience sample of 406 women participated in the study, 204 of the biomedical model and 202 of the humanised model. RESULTS: The differences in obstetrical results were (biomedical model/humanised model): onset of labour (spontaneous 66/137, augmentation 70/1, p=0.0005), pain relief (epidural 172/132, no pain relief 9/40, p=0.0005), mode of delivery (normal vaginal 140/165, instrumental 48/23, p=0.004), length of labour (0-4â hours 69/93, >4â hours 133/108, p=0.011), condition of perineum (intact perineum or tear 94/178, episiotomy 100/24, p=0.0005). The total questionnaire score (100) gave a mean (M) of 78.33 and SD of 8.46 in the biomedical model of care and an M of 82.01 and SD of 7.97 in the humanised model of care (p=0.0005). In the analysis of the results per items, statistical differences were found in 8 of the 9 subscales. The highest scores were reached in the humanised model of maternity care. CONCLUSIONS: The humanised model of maternity care offers better obstetrical outcomes and women's satisfaction scores during the labour, birth and immediate postnatal period than does the biomedical model.

Melanoma is one of the most frequently metastasizing malignant neoplasias. This study examines an experimental model of pulmonary metastasis and the B16F10 cell subline, highly metastatic in the lung. Antimetastatic effects of the flavonoids tangeretin, rutin, and diosmin were analyzed, and at the same time an analysis of the metastatic activity of ethanol was performed, considered to be necessary because it is used as a vehicle for administering the flavonoids. Lentini's model, which complements the macroscopic evaluation of nodule numbers by using a stereoscopic microscope and image analysis at the microscopic level, was used. The greatest reduction in the number of metastatic nodules (52%) was obtained with diosmin; similarly, the percentages of implantation, growth index, and invasion index (79.40, 67.44, and 45.23%, respectively), were all compared with those of the ethanol group, considered to be an effective control group. Rutin- and tangeretin-treated groups also showed reductions of the same index compared with the ethanol group. It would seem that structural factors would better explain these results and the antimetastatic activity of each flavonoid and the respective metabolites.

INTRODUCTION: Melanoma is one of the neoplasias that most frequently metastasize, especially in the lung, where represents a challenge in oncology since current treatment is ineffective, and mortality is high. MATERIAL AND METHODS: Swiss mice (n = 52) were inoculated with 0.5 x 106 B16F10 cell lines and, later, given an oral administration of grape-seed extract, red wine or ethanol. Metastatic nodules on the lung surface were counted and, after processing for microscopy, five sections were selected for image analysis and the invasion index was calculated. RESULTS: Macroscopic analysis showed that grape-seed extract and red wine reduced the number of metastatic nodules by 26.07 and 20.81%, respectively, compared with a control group treated with ethanol. Microscopically, the reduction in the invasion index was 31.65 for grape-seed extract and 17.57% for red wine. CONCLUSION: Ethanol administration significantly increased pulmonary metastasis while grape-seed extract and red wine led to their reduction.

OBJECTIVES: To analyse factors associated to "failure" in patients under antibiotic (AB) treatment at a third level hospital. PATIENTS AND METHODS: All patients receiving an AB treatment along April 2012 were prospectively observed and factors associated to failure were analyzed. Failure was defined as clinical or microbiological failure, relapse or death. Statistically significance was established as p<0.05. RESULTS: 602 of 1,265 admitted patients during the study month included an AB in their medical prescriptions, being 178 considered as prophylactic AB prescriptions, 342 empirical treatments and 82 directed treatments as empiric treatments. Ceftriaxone and levofloxacin were the most used AB; choice of empirical and directed treatments were in line with protocols in 71% (242 of 342 cases) and 67% (55 of 82), respectively. Of all the patients receiving antibiotics for therapy (n=424), 402 had infection criteria (in 22 cases antibiotic treatment was deemed unnecessary since the patient showed no infectious process). Of these, 292 (72%) showed a good evolution, while the others were considered as failed therapies, either because of microbiological persistence in 49 (12.8%), relapse in 31 (7.71%) and death in en 30 (7.46%). Factors associated to "failure" were Charlson score ≥3 (OR 3.35; 95%CI 1.602-7.009); empirical and/or directed treatment not in keeping with the protocol (OR 5.68; 95%CI 2.898-11.217); and infection by ESBL and/or ciprofloxacin resistant E. coli (OR 4.43; 95%CI 1.492-13.184). CONCLUSIONS: A high rate of AB prescriptions in admitted patients correspond to empirical infection treatment, being ceftriaxone and levofloxacin the most used AB. Inadequate empirical and/or directed treatment is associated to clinical or microbiological failure and death.

OBJECTIVES: get to know, analyze and describe the current situation of the Delivery and Birth Plans in our context, comparing the delivery and birth process between women who presented a Delivery and Birth Plan and those who did not. METHOD: quantitative and cross-sectional, observational, descriptive and comparative cohort study, carried out over two years. All women who gave birth during the study period were selected, including 9303 women in the study. RESULTS: 132 Delivery and Birth Plans were presented during the first year of study and 108 during the second. Among the variables analyzed, a significant difference was found in "skin to skin contact", "choice of dilation and delivery posture", "use of enema", "intake of foods or fluids", "eutocic deliveries", "late clamping of the umbilical cord" and "perineal shaving". CONCLUSIONS: the Delivery and Birth Plans positively influence the delivery process and its outcome. Health policies are needed to increase the number of Delivery and Birth Plans in our hospitals.

BACKGROUND: the hypothesis of this study is that there are not enough validated questionnaires that measure the impact of networks to support breastfeeding for the Spanish speaking population. OBJECTIVE: For this reason, we ask as a general objective of this study, to develop and validate (in terms of content and construct) a quantitative instrument of measure. METHOD: We evaluated the content validity, subjecting the survey to a breastfeeding expert's opinion in the Region of Murcia. The pilot test was conducted between the months of March and April 2014. Surveys were carried out directly by users who attended the breast-feeding support group "Lactando". For construction validity, a factor analysis was conducted, which determined the different dimensions that the survey could measure. A description of each of the items on the statistics was conducted. Through principal component analysis, the total variance explained was obtained, determining the factors that define the elements. RESULTS: Through factor analysis, the questionnaire has a high internal consistency for its five components (satisfaction, consultations, experience, problems and support), obtaining values from 0.942 to 0.632. And a high percentage of total variance explained (11,157% - 5,093%). CONCLUSION: This study has served to create a relevant and valid in terms of content and construction, instrument, capable of measuring the impact of networks of support for breastfeeding through 5 dimensions.
Antecedentes: partimos de la hipótesis de que no existen suficientes cuestionarios validados que midan el impacto de las redes de apoyo a la lactancia materna para población hispano hablante. Objetivo: Por ese motivo, nos planteamos como objetivo general de este trabajo, elaborar y validar (a nivel de contenido y constructo) un instrumento de medida cuantitativa. Método: Se evaluó la validez de contenido sometiendo el cuestionario a un juicio de expertos en lactancia materna de la Región de Murcia. La prueba piloto se llevó a cabo entre los meses de marzo y abril de 2014. Las encuestas fueron realizadas directamente por las usuarias que acudían al grupo de apoyo a la lactancia "Lactando". Para la validez de constructo se realizó un análisis factorial con el que se determinaron las distintas dimensiones que el cuestionario podría medir. Se realizó una estadística descriptiva de cada uno de los ítems. A través del análisis de componentes principales, se obtuvo la varianza total explicada, determinando así, los factores con los elementos que los definían. Resultados: A través del análisis factorial, el cuestionario obtuvo una alta consistencia interna para sus cinco componentes (satisfacción, consultas, experiencia, problemas y apoyo), consiguiendo valores de 0,942 a 0,632. Y un porcentaje de varianza total explicada elevado (11,157% - 5,093%). Conclusión: Este estudio ha servido para crear un instrumento pertinente y válido a nivel de contenido y de constructo, capaz de medir el impacto de las redes de apoyo a la lactancia a través de 5 dimensiones.

OBJETIVO: Staphylococcus aureus resistente a meticilina (MRSA) y las enterobacterias productoras de betalactamasas (ESBL-E) pueden complicar el tratamiento de las infecciones del pie del diabético (DFIs). El objetivo de este estudio fue determinar los factores de riesgo de las infecciones por estos microorganismos en el pie del diabético. MATERIAL Y MÉTODOS: Estudio observacional prospectivo de 167 pacientes consecutivos con infecciones del pie del diabético. El diagnóstico y gravedad de las infecciones se basó en la guía de la Infectious Disease Society of America (IDSA). Para identificar los factores de riesgo de las infecciones por MRSA y (ESBL-E) se llevó a cabo mediante un estudio multivariante. RESULTADOS: S. aureus fue el microorganismo más aislado (n= 82; 37,9 %) seguido por Escherichia coli (n= 40; 18,5%). El 57,3% de S. aureus fueron MRSA y el 70% de Klebsiella pneumoniae y el 25% de E. coli eran productores ESBL, respetivamente. Los factores de riesgo independientes de las infecciones por MRSA fueron las úlceras profundas [OR 8,563; IC 95% (1,068-4,727)], uso previo de fluoroquinolonas [OR 2,78; IC 95% (1,156-6,685)] y la vasculopatía periférica [OR 2,47; IC 95% (1.068-4.727)], mientras que para las infecciones por (ESBL-E) lo fueron osteomielitis [OR 6,351; 95% IC 95% (1,609-25,068)] y el uso previo de cefalosporinas [OR 5,824; IC 95% (1,517-22,361)]. CONCLUSIONES: MRSA y ESBL-E han adquirido una gran relevancia clínica en las DFIs. La disponibilidad de sus factores de riesgo es muy conveniente para elegir el tratamiento empírico en las formas graves
PURPOSE: Methicillin-resistant Staphylococcus aureus (MRSA) and extended-spectrum Beta-lactamase-producing Enterobacterales (ESBL-E) may complicate the treatment of diabetic foot infections (DFIs). The aim of this study was to determine the risk factors for these pathogens in DFIs. MATERIAL AND METHODS: This was a prospective observational study of 167 consecutive adult patients with DFIs. The diagnosis and severity of DFIs were based on the Infectious Disease Society of America (IDSA) classification system. Multivariate analyses were performed in order to identify risk factors for MRSA and ESBL-E infections. RESULTS: S. aureus was the most isolated pathogen (n=82, 37.9 %) followed by Escherichia coli (n= 40, 18.5%). MRSA accounted for 57.3% of all S. aureus and 70% of Klebsiella pneumoniae and 25% of E. coli were ESBL producers, respectively. Deep ulcer [OR 8,563; 95% CI (1,068-4,727)], previous use of fluoroquinolones [OR 2,78; 95% CI (1,156-6,685)] and peripheral vasculopathy [OR 2,47; 95% CI (1.068-4.727)] were the independent predictors for MRSA infections; and osteomyelitis [OR 6,351; 95% CI (1,609-25,068)] and previous use of cephalosporins [OR 5,824; 95% CI (1,517-22,361)] for ESBL-E infections. CONCLUSIONS: MRSA and ESBL-E have adquired a great clinical relevance in DFIs. The availability of their risk factors is very convenient to choose the empirical treatment in severe forms

BACKGROUND AND OBJECTIVE: The hypoparathyroidism is one of the most important complications in the patients submitted to thyroid surgery. The aim is to analyze across a multivariate statistical analysis the risks factors for the development of transient and permanent hypoparathyroidism following the multinodular goiter (MG) surgery. PATIENTS AND METHOD: Between 1970 and 1999, 672 thyroidectomies by MG were reviewed. It was considered transient hypoparathyroidism when the calcemia was minor of 7.5 mg/dl or when being minors of 8.5 mg/dl the patient was presenting symptomatology for the hipocalcemia. The hypoparathyroidsm was considered permanent when the calcemia was minor of 8.5 mg/dl to the year of the surgery. RESULTS: The hypoparathyroidism appeared in 75 patients (11.2%), 20 with symptomatology (3%), persisting like permanent 6 cases (0.9%). The risk factors for the development of this were the hyperthyroidism (p = 0.0370), and the surgical technique (p < 0.00001) (unilateral versus bilateral surgery), persisting in the multivariate analysis both variables. With respect to the permanent hypoparathyroidism, the risk factor was the toxic MG (p = 0.0109), persisting as independent risk factor in the multivariate analysis (RR = 2.3). CONCLUSIONS: The principal risk factor of permanent hypoparathyroidism in the MG surgery is the presence of hyperthyroidism.

Background: overweight and obesity have been increasing, and university students are an important target for prevention programs. Previous studies have reported differences in the diagnosis between different anthropometric methods, so some students can be misclassified depending on the method used. Objective: to evaluate the efficacy of different anthropometric methods to detect those university students in a probable status of overweight, including a comparison with a new proposed method, the normalized weight-adjusted index (NWAI). Methods: different anthropometric methods (waist circumference, waist-hip ratio, waist-height ratio, body mass index, conicity index, bioimpedance and Brozek, Siri and Heath-Carter equations) were calculated for 505 university students. By k-means cluster analysis, students with higher values according to variables involved in overweight were identified. Parameters of accuracy were calculated by operating characteristic curves. Results: NWAI showed significant correlations with the most used methods. Prevalence of students with body fat excess varied from 5.9% to 48.4% for women and from 8.5% to 49.0% for men depending of the method employed, being demonstrated a great variability between the different methodologies. Body mass index for women and waist circumference for men resulted to be the most accurate methods to detect a probable situation of excess of body fat or cardiovascular risk associated. NWAI resulted also a good alternative for overweight classification. Conclusions: differences between anthropometric methods for overweight and cardiovascular disease risk classification were confirmed. Classical cut-off point may misdiagnose overweight or health risk in Spanish university students depending of the method employed
Introducción: el sobrepeso y la obesidad han ido en aumento, y los estudiantes universitarios son un objetivo importante para los programas de prevención. Estudios previos demuestran diferencias en el diagnóstico según el método antropométrico utilizado. Objetivo: evaluar la eficacia de diferentes métodos antropométricos para detectar a los estudiantes universitarios en un probable estado de sobrepeso y comparar con un nuevo método, el índice normalizado ajustado al peso (INAP). Metodología: se utilizaron diferentes métodos antropométricos (circunferencia de cintura, cociente cintura cadera, relación cintura-altura, índice de masa corporal, índice de conicidad, bioimpedancia y ecuaciones de Brozek, Siri y Heath-Carter) para 505 estudiantes universitarios. Se identificaron los estudiantes con valores más altos de acuerdo a las variables involucradas en el sobrepeso y se calculó la precisión de los distintos métodos antropométricos. Resultados: el INAP mostró correlaciones significativas con los métodos más utilizados. La prevalencia de estudiantes con exceso de grasa corporal varió para las mujeres del 29,4% al 78,1% y para los varones del 12,0% al 54,0% dependiendo del método empleado. El índice de masa corporal para las mujeres y la circunferencia de cintura para los hombres fueron los métodos más precisos para detectar un probable exceso de grasa corporal o riesgo cardiovascular asociado. El INAP resultó una buena alternativa para la clasificación de sobrepeso. Conclusiones: se confirmaron las diferencias entre los métodos antropométricos para el sobrepeso y la estimación de riesgo cardiovascular. Los puntos de corte clásicos pueden diagnosticar erróneamente sobrepeso o riesgo para la salud en estudiantes universitarios españoles dependiendo del método empleado
