The risk of incident depression when assessed with the Lifestyle and Well-Being Index.

OBJECTIVES: Novel findings indicate links between unhealthy lifestyles and depression based on active inflammatory processes. Thus, identifying participants with poor habits could reveal differences in trends of incident depression. This study aimed to examine the association between an objective lifestyle assessment, as measured by the Lifestyle and Well-Being Index (LWB-I), and incident depression in healthy participants of a Spanish cohort. STUDY DESIGN: This was a longitudinal analysis of a subsample of 10,063 participants from the Seguimiento Universidad de Navarra cohort study. METHODS: Group comparisons and Cox proportional hazard models were conducted using the LWB-I, which categorizes the sample into groups with healthy and unhealthy lifestyles and well-being. The main outcome was incident depression as well as secondary outcomes. RESULTS: Those classified to the transition category of LWB-I were associated with a hazard ratio of 0.67 (95% confidence interval: 0.52-0.87), and those in the excellent category showed a hazard ratio of 0.44 (95% confidence interval: 0.33-0.58), which in both groups reflects a significantly lower risk of incident depression compared with the group including those classified in the poor LWB-I level. Moreover, the available sensitivity analyses concerning time of depression diagnosis or antidepressant treatment further supported the role of nutrition and physical activity on incident depression. Interestingly, throughout the follow-up, incident depression was inversely related to healthier daily habits as measured by the LWB-I. CONCLUSIONS: A global assessment of lifestyles such as the LWB-I provides valuable insight into the complex relationship between lifestyle factors and their link to depression risk.

Strength of association of classical vascular risk factors in young patients with ischaemic stroke: a case-control study.

INTRODUCTION: Recent studies have reported an increasing incidence of ischaemic stroke among young adults. However, the strength of the association between traditional vascular risk factors has not been fully established. METHODS: We compared 120 patients with a first ischaemic stroke before the age of 55 years admitted to the stroke unit of our centre with 600 healthy non-stroke controls from a population-based cohort study (HERMEX), matched for sex. Risk factors assessed included: hypertension, obesity, auricular fibrillation, current smoking, estimated glomerular filtration rate (eGFR), total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides, high-density lipoprotein cholesterol (HDL-C) and diabetes mellitus. We used logistic regression analysis and calculated population attributable risk. We performed an overall analysis, by sex and aetiological subgroup. RESULTS: Using logistic regression analysis, we found that overall, the significant risk factors were: hypertension (OR: 1.58; 95%CI: 1.01-2.50), atrial fibrillation (OR: 4.77; 95%CI: 1.20-19.00), low eGFR (OR: 4.74; 95%CI: 1.3-21.94) and low HDL-C (OR: 5.20; 95%CI: 3.29-8.21), as well as smoking for males (OR: 1.86; 95%CI: 1.14-3.03). LDL-C showed an inverse association with stroke. The population attributable risk for HDL-C was 37.8% and for hypertension 21.1%. In terms of aetiological subgroups, only low HDL-C was associated with stroke of undetermined aetiology. CONCLUSIONS: Hypertension, auricular fibrillation, low eGFR, and low HDL-C, plus tobacco use in men, are the main risk factors among patients under 55 years of age with a first ischaemic stroke. We believe that it would be of particular interest to further explore the management of low HDL-C levels as part of preventive strategies in young stroke patients.

Cost-consequence analysis of extended loading dose of anti-VEGF treatment in diabetic macular edema patients.

BACKGROUND: The DRCR.net Protocol T clinical trial assessed the comparative efficacy and safety of anti-VEGF treatments including aflibercept, ranibizumab and bevacizumab in diabetic macular edema (DME). Post -hoc analyses showed that after a 12-week induction period, there was still DME resolution in an increasing number of patients through week 24. PURPOSE: To assess clinical and cost consequences of extending the anti-VEGF loading dose from 3 to 6 monthly injections in patients with persistent DME in Spain. METHODS: From a hospital pharmacy perspective, a cost-consequence analysis model was developed to estimate the incremental cost needed to obtain an additional response at month 6. To estimate drug treatment costs, ex-factory prices (€, 2019) were considered for aflibercept, ranibizumab and bevacizumab. Response/nonresponse rates at 3/6 months were obtained from the Protocol T 24-week post hoc analysis (n = 546). Persistent DME was present in 50.8 and 31.6% of the 190 aflibercept-treated patients at month 3 and month 6, respectively. Of the 176 ranibizumab- and 180 bevacizumab-treated patients, 53.2 and 72.9%, respectively, had persistent DME at month 3, and 41.5 and 65.6%, respectively, had persistent DME at month 6. Sensitivity analysis considered the split of bevacizumab vials. RESULTS: Extending the loading dose in nonresponder patients would cost €214,862.57, €208,488.98 and €134,483.16 to obtain 37, 21 and 13 additional aflibercept, ranibizumab and bevacizumab responder patients, respectively. The total number of extended injections (months 3-6) used in patients with persistent DME at month 6 was 180, 219 and 354 for aflibercept, ranibizumab and bevacizumab, respectively. CONCLUSIONS: To extend the anti-VEGF loading dose from 3 to 6 injections necessitates investing €5882.77 (8 injections), €10,091.03 (14 injections) and €10,198.59 (30 injections) per additional responder patient (3-month nonresponders and 6-month responders) to aflibercept, ranibizumab and bevacizumab, respectively. For the total of patients treated, on average €7927.02 (14 injections) per additional responder patient would be needed.

Open angle glaucoma secondary to endogenous cortisone due to pituitary microadenoma in a young patient, a case report. / Glaucoma de ángulo abierto secundario a cortisona endógena por microadenoma hipofisario en un paciente joven, a propósito de un caso.

CASE REPORT: A 31-year-old male was referred for evaluation after being diagnosed with Cushing syndrome secondary to a pituitary microadenoma. He presented with a reduced visual acuity and high intraocular pressure (IOP) of 48mmHg in both eyes. The examination with biomicroscopy showed normal anterior segment, increased cup to disc ratio, and open angle. There was a moderate-advanced involvement in the visual field. The patient was diagnosed with glaucoma secondary to endogenous corticosteroids, and medical treatment was initiated pending the removal of the adenoma. The IOP did not return to normal after the incomplete removal of the adenoma, so a trabeculectomy was performed to control the IOP. As conclusions: In the case of an ocular hypertension with pituitary tumour, secondary glaucoma to endogenous cortisone should be suspected. Early treatment of the tumour is necessary to bring the cortisone and IOP levels back to normal. Late diagnosis or incomplete treatment of these tumours may lead to not obtaining adequate IOP control.

Impact of the 2005 and 2010 Spanish smoking laws on hospital admissions for tobacco-related diseases in Valencia, Spain.

OBJECTIVES: This study aimed to assess the impact of the latest smoke-free legislation on hospital admission rates due to smoking-related diseases in Spain. STUDY DESIGN: A retrospective cohort study was conducted to evaluate changes in hospital admission rates for cardiovascular, respiratory diseases, and smoking-related cancer in Valencia, Spain, during the period 1995-2013. Law 28/2005 and then law 42/2010 prohibited smoking in bars and restaurants as well as playgrounds and access points to schools and hospitals. METHODS: General population data by age and sex were obtained from the National Institute of Statistics census. Data on hospital admissions were obtained from the Minimum Basic Data Set. Diagnoses were codified according to the International Classification of Diseases-9th revision. Data from all hospitals of the Valencian Community from 1995 to 2013 were analysed. Trend analyses in the periods before and after the approval of the 2005 law were conducted using least-squares linear regression models. RESULTS: Adjusted hospital admission rates per 100,000 inhabitants for cardiovascular diseases significantly decreased after the 2005 Law (from 550.0/100,000 in 2005 to 500.5/100,000 in 2007), with a further decrease (to 434.6/100,000) in 2013, after the 2010 Law. Reductions in hospital admissions were seen in men and women, although declining trends were more marked in men. Hospital admission rates for respiratory diseases showed a reduction of a lower magnitude, whereas for smoking-related cancer admissions there was a slight decline only among men. CONCLUSIONS: The Spanish comprehensive smoking ban resulted in a remarkable reduction of the adjusted rate of hospital admissions mainly associated to cardiovascular diseases. The decrease in the number of persons requiring in-patient care is relevant and may be viewed as an improvement of the public's health.

Segmentation of gliomas in 18F-fluorocholine PET/CT. A multiapproach study. / Segmentación de gliomas con PET/TC con 18F-fluorocolina. Estudio multiaproximación.

AIM: Our aim was two-fold, to study the interobserver agreement in tumour segmentation and to search for a reliable methodology to segment gliomas using 18F-fluorocholine PET/CT. METHODS: 25 patients with glioma, from a prospective and non-randomized study (Functional and Metabolic Glioma Analysis), were included.Interobserver variability in tumour segmentation was assessed using fixed thresholds. Different strategies were used to segment the tumours. First, a semi-automatic tumour segmentation was performed, selecting the best SUVmax-% threshold for each lesion. Next we determined a variable SUVmax-% depending on the SUVmax. Finally a segmentation using a fixed SUVmax threshold was performed. To do so, a sampling of 10 regions of interest (ROI of 2.8cm2) located in the normal brain was performed. The upper value of the sample mean SUVmax±3 SD was used as cut-off. All procedures were tested and classified as effective or not for tumour segmentation by two observer's consensus. RESULTS: In the pilot segmentation, the mean±SD of SUVmax, SUVmean and optimal SUVmax-% threshold were: 3.64±1.77, 1.32±0.57 and 21.32±8.39, respectively. Optimal SUVmax-% threshold showed a significant association with the SUVmax (Pearson=-0.653, p=.002). However, the linear regression model for the total sample was not good, that supported the division in two homogeneous groups, defining two formulas for predicting the optimal SUVmax-% threshold. As to the third procedure, the obtained value for the mean SUVmax background+3 SD was 0.33. This value allowed segmenting correctly a significant fraction of tumours, although not all. CONCLUSION: A great interobserver variability in the tumour segmentation was found. None of the methods was able to segment correctly all the gliomas, probably explained by the wide tumour heterogeneity on 18F-fluorocholine PET/CT.

Update on the usefulness of optical coherence tomography in assessing the iridocorneal angle. / Actualización de la utilidad de la tomografía de coherencia óptica para el estudio del ángulo iridocorneal.

The iridocorneal angle, due to its implications in the physiopathology of aqueous humour drainage, is a fundamental structure of the anterior chamber. Anterior segment optical coherence tomography is a rapid and non-invasive technique that obtains images in vivo. The high resolution allows it to analyse the normal anatomy of the angle, any alterations, and the changes that occur after different therapeutic interventions. Anterior segment optical coherence tomography technology has evolved to provide images that allow the identification and quantification of the angular structures in healthy subjects and in glaucoma patients, and especially the trabecular meshwork and the Schlemm's canal. It also enables the angle width to be quantified, with some objective parameters that have been standardised in recent years, such as the trabecular-iris angle, the angle opening distance, and the trabecular-iris area. This technique has multiple uses in the study of the different mechanisms of angle closure, the evaluation of changes after a laser peripheral iridotomy or iridoplasty after cataract surgery, as well as after the implantation of phakic lenses.

Análisis morfométrico e índices corporales del capitán de la sabana / Morphometric analysis and body indexes of the catfish (Eremophilus mutisii)

RESUMEN Con el objetivo de caracterizar la morfometría e índices corporales de Eremophilus mutisii, se usaron treinta y tres peces (27 hembras y 6 machos) provenientes del río Bogotá, específicamente de la región de Suesca. La relación de aspecto de la aleta caudal se determinó mediante el software de análisis de imágenes ImageJ®. Se calculó el índice gonadosomático, hepatosomático y rendimiento en canal para cada pez. Para el análisis de los datos se usaron correlaciones, regresiones y técnicas de análisis multivariado (análisis discriminante canónico). Como resultado del estudio se encontró que el sexo no afecta la forma del cuerpo de los peces. La relación entre la longitud y el peso se ajustó para cada sexo. La relación de aspecto de la aleta caudal presentó un promedio de 1,57 lo que sugiere que la especie presenta hábito sedentario o de natación lenta. El índice gonadosomático de las hembras en maduración (media: 14,43%, rango: 8,84% a 23,22%) aumentó en función del peso corporal y fue mayor que el de los machos (media: 5,32%, rango: 2,31% a 8,29%). Por lo tanto, el rendimiento de la carcasa fue menor en las hembras en maduración. La media del índice hepatosomático para hembras fue 0,86% (rango: 0,43% a 1,88%) y para machos fue 0,63% (rango: 0,39% a 1,09%). En conclusión, Eremophilus mutisii es una especie sedentaria y las hembras se caracterizarán por presentar mayor índice gonadosomático y menor rendimiento en carcasa que los machos.

ABSTRACT With the aim of characterizing the morphometry and body indexes of Eremophilus mutisii, thirty-three fishes (27 females and 6 males) coming from the Bogotá river, specifically of the Suesca region, were used. The aspect ratio of the caudal fin was determined with the aid of the image analysis software ImageJ®. Gonadosomatic and hepatosomatic indexes and carcass yield were determined for each fish. Correlation, regression and multivariate (canonical discriminant analysis) techniques were used for data analysis. Results indicated that sex does not affect the body shape of the fishes. The relationship between length and weight was fitted for each sex. The average aspect ratio of the caudal fin was 1.57, which suggests that the species has sedentary habits or slow swimming. The gonadosomatic index of the maturing females (mean: 14.43 %; range: 8.84 % to 23.22 %) increased as a function of body weight and was greater than in males (mean: 5.32 %; range: 2.31 % to 8.29 %). Therefore, the carcass yield was lower in maturing females than in males. The mean of the hepatosomatic index for females was 0.86 % (range: 0.43 % to 1.88 %) and for males was 0.63 % (range: 0.39 % to 1.09 %). As a conclusion, Eremophilus mutisii is a sedentary fish species, and females exhibit greater gonadosomatic index and lower carcass yield than males.

Total polyphenol intake, polyphenol subtypes and incidence of cardiovascular disease: The SUN cohort study.

BACKGROUND AND AIMS: Polyphenol-rich diets have been associated with reduced risk of cardiovascular disease (CVD). However, few prospective epidemiological studies have examined the relationship between classes of ingested polyphenols and risk of CVD. Our aim was to evaluate the association between polyphenol intake and risk of major cardiovascular events in a prospective Spanish cohort. METHODS AND RESULTS: We included 17,065 university graduates (60.7% women, mean age: 37.2 years, age range: 20-89) followed-up for a mean of 10.1 years. Polyphenol intake was assessed at baseline using a validated semi-quantitative 136-item food frequency questionnaire and matching food consumption data with the Phenol-Explorer database. Cox proportional hazards models were used to estimate the adjusted hazard ratios (HR) and 95% confidence intervals (95% CI) for incident cardiovascular events (myocardial infarction, stroke or cardiovascular death). Cherries, chocolate, coffee, apples, and olives were the major sources of variability in polyphenol intake. Participants with higher flavonoids intake (fifth quintile) had a 47% lower incidence of cardiovascular events compared to those in the lowest quintile (HR: 0.53, 95% CI: 0.29-0.98; P for trend = 0.09) after adjusting for potential confounders. The results were non-significant for other polyphenol types. CONCLUSION: The intake of flavonoids showed an inverse association with risk of cardiovascular events in a prospective cohort of Spanish middle-aged adult university graduates.

[Adverse events related to medication in hospitals from the Valencian Community. EPIDEA Study 2005-2013]. / Eventos adversos relacionados con la medicación en los hospitales de la Comunidad Valenciana. Estudio EPIDEA 2005-2013.

OBJECTIVE: To determine the prevalence of Adverse Events related to Medication (AEM) in hospitals of the Valencian Community in the 2005-2013 study period, and to describe the associated risk factors and their impact. METHODS: This study is based on data and methodology of the Study of Prevalence of Adverse Events in hospitals (EPIDEA), since its inception in 2005 until 2013. AEM produced in each year were analyzed. RESULTS: We identified 344 AEM that occurred in 337 patients, among 35,103 patients studied, giving a prevalence of patients with AEM of 0.96% (IC95% 0.89-1.07). The most prevalent intrinsic risk factors for AEM were hypertension, diabetes and cancer. The most prevalent extrinsic risk factors were peripheral venous catheter, urinary catheter and central venous catheter. Therapeutic groups most frequently involved were systemic antibiotics, cardiovascular drugs and antineoplastics. The 61.17% of AEM was classified as moderate, followed by 27.18% as mild and 11.65% as severe. The 33.99% of EAM caused increase of the patient's stay and 39.90% of EAM caused the re-entry of patient. The 58.5% of AEM were avoidable. Mild AEM were avoidable in 46.3%, moderate AEM were avoidable in 60.3% and severe AEM were in 75% (p = 0.013). CONCLUSIONS: The prevalence of patients with AEM in hospitals of the Community of Valencia for the period 2005- 2013 was 0.96%. More than half of AEM were preventable, and preventability increases significantly with the severity of the event.

Cost of myopic patients with and without myopic choroidal neovascularisation. / Costes en pacientes miopes magnos con y sin neovascularización coroidea miópica.

OBJECTIVE: To study the costs associated with high myopia (HM) with choroidal neovascularisation (mCNV) or without mCNV. METHODS: Observational, retrospective, cross-sectional, and multicentre study (HM and mCNV) conducted on adult patients. Annualised medical direct cost (MDC) from the perspective of the National Health System, the non-medical direct cost (nMDC) from the patient perspective, and productivity losses were calculated. RESULTS: A total of 137 mCNV and 48 HM patients were included (mean age [SD]: 55.1 [2.8] vs. 54.7 [13.8]; P=.2), with 80% women in both groups. The observation time (months) ranged from 17.9 (9.6) right eye (RE) and 20.0 (9.7), left eye (LE) in mCNV and 47.1 (21.5) RE/45.5 (20.7) LE in MM. A higher percentage of emergency room visits was observed in mCNV vs. HM patients (41.7 vs. 25%; P=.06) and retinal specialists (91.2 vs. 77.1%; P=.01). The MDC was higher in mCNV: € 1,985 (95% CI: 1772-2198) vs. € 356 (251-480) HM, P<.001. The nMDC was also higher in mCNV: € 256 (11-524) vs. €19 (11-26) HM, P>.4. The number of affected eyes, the follow-up time, and the mCNV were factors associated with direct costs. The impact on work productivity was higher in mCNV (quite/very concerned): 27.7 vs. 10.4% HM. The mCNV showed a significant association with activity impairment (OR: 3.47, 95% CI: 10.101-1.195). CONCLUSIONS: mCNV involves higher medical costs than HM. In addition, mCNV patients have a greater need of care and assistive devices, and greater impact of the disease in their work productivity.

Long-term outcomes of phakic patients with diabetic macular oedema treated with intravitreal fluocinolone acetonide (FAc) implants.

PURPOSE: Diabetic macular oedema (DMO) is a leading cause of blindness in working-age adults. Slow-release, nonbioerodible fluocinolone acetonide (FAc) implants have shown efficacy in the treatment of DMO; however, the National Institute for Health and Care Excellence recommends that FAc should be used in patients with chronic DMO considered insufficiently responsive to other available therapies only if the eye to be treated is pseudophakic. The goal of this analysis was to examine treatment outcomes in phakic patients who received 0.2 µg/day FAc implant. METHODS: This analysis of the phase 3 FAME (Fluocinolone Acetonide in Diabetic Macular Edema) data examines the safety and efficacy of FAc implants in patients who underwent cataract extraction before (cataract before implant (CBI) group) or after (cataract after implant (CAI) group) receiving the implant. The data were further examined by DMO duration. RESULTS: Best corrected visual acuity (BCVA) after 36 months was comparable in the CAI and CBI groups. Both the percentage of patients gaining ≥ 3 lines of vision and mean change in BCVA letter score were numerically greater in the CAI group. In addition, most patients who underwent cataract surgery experienced a net gain in BCVA from presurgery baseline as well as from original study baseline. CONCLUSIONS: These data support the use of 0.2 µg/day FAc implants in phakic as well as in pseudophakic patients. These findings will serve as a pilot for design of future studies to evaluate the potential protective effect of FAc implants before cataract surgery in patients with DMO and cataract.

[New perspectives in the approach to diabetic macular edema. Aflibercept therapy]. / Nuevas perspectivas en el abordaje del edema macular diabético. Tratamiento con aflibercept.

The VISTA and VIVID trials were conducted to compare the safety and efficacy of two intravitreal injection (IVI) regimens of aflibercept versus macular laser photocoagulation for the treatment of diabetic macular edema (DME). These double-masked, phase III clinical trials randomized (461/402) patients with DME to receive either 2mg aflibercept IVI every 4 weeks (2q4) or 2mg aflibercept IVI every 8 weeks (2q8) after 5 initial monthly doses vs macular laser photocoagularion. The primary efficacy endpoint was the mean change in best corrected visual acuity (BCVA) from baseline to week 52. Secondary efficacy endpoints were the change in central retinal thickness (CRT), the proportion of patients who gained ≥10 amd ≥15 Early Treatment Diabetic Retinopathy Study (ETDRS) letters, and the change in the National Eye Institute Visual Function Questionnaire (NEI VFQ-25) in near and distance vision. The mean BCVA gains in the 2q4 and 2q8 groups versus the laser group were 12.5 and 10.7 versus 0.2 letters (p<0.0001) in VISTA, and 10.5 and 10.7 versus 1.2 letters (p<0.0001) in VIVID. The proportions of patients gaining ≥ 15 letters and the proportion of patients with an improvement of > 2 levels in the severity of diabetic retinopathy was significant in the treatment groups versus the laser group. Mean reductions in CRT in the 2q4 and 2q8 groups vs the laser group were 185.9 and 183.1 versus 73.3 µm (p<0.0001) in VISTA, and 195.0 and 192.4 versus 66.2 µm (p<0.0001) in VIVID. The incidences of ocular and nonocular adverse events were similar in all groups. In conclusion, IIV aflibercept demonstrated statistically significant superiority in improvement in BCVA and reduction in DME over laser, with similar efficacy in the 2q4 and 2q8 groups in VISTA and VIVID.

Development of type 2 diabetes mellitus thirty-one years after Billroth II in a patient asking for diabetes surgery.

INTRODUCTION: Diabetes surgery in obese and slim patients seems to be a superior alternative to the current medical treatment. Gastric bypass is an alternative treatment for diabetes. Nevertheless, there are still doubts whether diabetes can recur if you gain weight or if the effects are maintained over time. Other questions refer to the type of surgery to make the bypass limb length or reservoir size for the resolution of the Diabetes Mellitus. PRESENTATION OF CASE: Male patient 69-year-old came to us in order to perform tailored One Anastomosis Gastric Bypass (BAGUA) to treat his type 2 diabetes mellitus and metabolic syndrome. He has a history of peptic ulcer treated with subtotal gastrectomy and Billroth II reconstruction 49 years ago. He currently is not obese and developed diabetes 31 years after surgery. DISCUSSION: Globally there are no reports of patients with normal BMI that after performing gastric bypass developed diabetes mellitus. There are cases where obese diabetic patients after gastric bypass improve or remits the T2DM, but it relapses due to insufficient weight loss or gain it. The patient with gastric bypass Billroth II type, should not developed diabetes. He is normal weight and not had weight gain that could be linked to the development of diabetes. CONCLUSIONS: The results generated by bariatric surgery are encouraging, but still do not clarify the precise way how surgery produces rapid improvement of systemic metabolism as in diabetes, but in our patient, the effect was quite different because the gastric bypass had no protective effect against diabetes.

INTRODUCCIÓN: La cirugía de la diabetes en pacientes obesos y delgados parece ser una alternativa superior al tratamiento médico actual. El bypass gástrico es un tratamiento alternativo al tratamiento médico actual. Sin embargo, todavía hay dudas sobre si la diabetes puede reaparecer si hay aumento de peso o si se mantienen los efectos en el tiempo. Otras preguntas se refieren al tipo de cirugía para hacer la longitud del remanente gástrico o el tamaño del reservorio para la resolución de la Diabetes Mellitus. Presentación del caso: Paciente masculino de 69 años de edad, vino a nosotros con el fin de realizar el bypass gástrico de una anastomosis a medida (BAGUA) para tratar su diabetes mellitus tipo 2 y el síndrome metabólico. Tiene antecedentes de úlcera péptica tratado con gastrectomía subtotal y reconstrucción tipo Billroth II hace 49 años. Actualmente él no es obeso y desarrolló diabetes 31 años después de la cirugía. DISCUSIÓN: A nivel mundial no hay reportes de pacientes con IMC normal que después de realizar un bypass gástrico desarrollaron diabetes mellitus. Hay casos en que los pacientes diabéticos obesos después del bypass gástrico mejoran o remite la DMT2, pero reaparece debido a la pérdida de peso insuficiente o reganancia de él. El paciente con un bypass gástrico tipo Billroth II, no debió desarrollar diabetes. Él tiene peso normal y no ha aumentado de peso que podría estar relacionado con el desarrollo de diabetes. CONCLUSIÓN: Los resultados generados por la cirugía bariátrica son alentadores, pero aún no aclaran la forma precisa cómo la cirugía produce una rápida mejoría del metabolismo sistémico como la diabetes, pero en nuestro paciente, el efecto fue muy diferente debido a que el bypass gástrico no tuvo un efecto protector contra la diabetes.

Changes of body composition in patients with BMI 23-50 after tailored one anastomosis gastric bypass (BAGUA): influence of diabetes and metabolic syndrome.

BACKGROUND: The use of bariatric surgery to treat diabetes mellitus (DM) requires procedures developed for morbid obese in patients with normal and over-weight. Therefore, we started tailoring one anastomosis gastric bypass (BAGUA) adapted to each patient. This study analyzes changes in body composition (BC) of patients with BMI 23-50 after BAGUA as well as influence of DM and MS. METHODS: We studied 79 (37 diabetic and 42 non-diabetic) patients (BMI 23-50) who completed all evaluation appointment (preoperative, 10 days, 1, 3, 6, and 12 months) after tailored BAGUA for obesity, diabetes, or diabesity. Patients were classified according to BMI (23-29, 30-34, 35-50) and bearing or not diabetes. Variables are components of BC as well as DM and MS. RESULTS: Preoperatively, mean values of weight varied 37 kg (78-115 kg), muscle mass (MM) 8 kg (54-62 kg), while fat mass (FM) 30 kg (22-53 kg). Basal metabolism (BM) was higher in diabetic. After surgery, percentage (%) of excess weight loss (%EWL) ranged from 76 % (BMI 35-50) to 128 % (BMI 23-29), FM 56 % (BMI 23-29) to 65 % (BMI 35-50), without differences bearing DM. MM 12 % (non-diabetics BMI 30-34) to 17 % (diabetics BMI 35-50) and visceral fat (VF) 50 % (diabetics BMI 30-34) to 56 % (non-diabetics BMI 35-50). CONCLUSIONS: After tailored BAGUA, MM maintains steady while FM is highly reduced and variable. BM is reduced in all groups. Diabetics lose less weight and VF but more MM than non-diabetic patients. Preoperative presence of MS influences the changes in BC.

Super obese behave different from simple and morbid obese patients in the changes of body composition after tailored one anastomosis gastric bypass (BAGUA).

INTRODUCTION: Super obese patients behave different from simple and morbid obese patients when they reach final changes of body composition (BC) after bariatric surgery. This has led us to tailor One Anastomosis Gastric Bypass (BAGUA) to achieve better results in this group of patients. PATIENTS AND METHODS: We studied 83 (37 diabetic and 46 nondiabetic BMI 30 and up) patients who completed all evaluation appointment (preoperative, 10 days, 1, 3, 6 and 12 months) after tailored BAGUA for diabesity. We used the Tanita body composition analyzer BC-420 MA by the method of single frequency impedance to analyze the evolution of BC in patients classified by BMI 30 - 34,9, 35 - 50, and >50. RESULTS: While preoperative excess weight presented dramatic decreases after tailored BAGUA in all the groups, super obese have different final BC. Diabetics retained more fat mass and visceral fat, where super obese have double (14 kg) that simple obese patients (6 kg), they lost more muscle mass, and have higher basal metabolism. The final BC is altered in all parameters if diabetes is added. CONCLUSIONS: The reduction of the preoperative excess weight is motivated largely by the tailored effect of BAGUA. Patients BMI 30-50 behaved homogeneous in BC after surgery while patients BMI >50 behave different. Super obese lose less weight, retained more fat mass, visceral fat, bone mass, and total water. This effect should be treated by more aggressive surgery by measuring the entire small intestine to make a proper exclusion (tailored) to achieve homogeneous effects.

Introducción: Los pacientes súper obesos se comportan de manera distinta a los pacientes con obesidad simple y obesidad mórbida cuando alcanzan los cambios finales de la composición corporal (CC) tras la cirugía bariátrica. Esto nos condujo a individualizar la anastomosis única de derivación gástrica (BAGUA) para conseguir mejores resultados en estos pacientes. Pacientes y métodos: Estudiamos a 83 pacientes (37 diabéticos y 46 no diabéticos, con IMC ≥30) que completaron todos las visitas de evaluación (preoperatorio, 10 días, 1, 3, 6 y 12 meses) tras la cirugía personalizada BAGUA para la obesidad. Empleamos el analizador de la composición corporal Tanita CC-420 MA mediante el método de impedancia de un única frecuencia para analizar la evolución de la CC en pacientes clasificados por el IMC 30 - 34,9, 35 - 50, y > 50. Resultados: Mientras que el exceso de peso preoperatorio mostró unas reducciones drásticas tras la cirugía BAGUA personalizada en todos los grupos, los súper obesos tuvieron una CC final diferente. Los diabéticos retuvieron más masa grasa y grasa visceral, mientras que los súper obesos mostraban el doble (14 kg) que los pacientes con obesidad simple (6 kg), perdieron más masa muscular y tuvieron un mayor metabolismo basal. La CC final se altera en todos sus parámetros si se añade la diabetes. Conclusiones: La reducción del exceso de peso preoperatorio está motivada en gran medida por el efecto de la cirugía BAGUA personalizada. Los pacientes con un IMC entre 30-50 se comportan de forma homogénea en la CC tras la cirugía mientras que los pacientes con un IMC > 50 se comportan diferentemente. Los súper obsesos pierden menos peso, retienen más masa grasa, grasa visceral, masa ósea y agua total. Este efecto debería tratarse con una cirugía más agresiva midiendo todo el intestino delgado para realizar una exclusión adecuada (personalizada) para conseguir unos efectos homogéneos.

Analysis of stroke care resources in Spain in 2012: have we benefitted from the Spanish Health System's stroke care strategy?

INTRODUCTION: The Spanish Health System's stroke care strategy (EISNS) is a consensus statement that was drawn up by various government bodies and scientific societies with the aim of improving quality throughout the care process and ensuring equality among regions. Our objective is to analyse existing healthcare resources and establish whether they have met EISNS targets. MATERIAL AND METHODS: The survey on available resources was conducted by a committee of neurologists representing each of Spain's regions; the same committee also conducted the survey of 2008. The items included were the number of stroke units (SU), their resources (monitoring, neurologists on call 24h/7d, nurse ratio, protocols), SU bed ratio/100,000 inhabitants, diagnostic resources (cardiac and cerebral arterial ultrasound, advanced neuroimaging), performing iv thrombolysis, neurovascular interventional radiology (neuro VIR), surgery for malignant middle cerebral artery (MCA) infarctions and telemedicine availability. RESULTS: We included data from 136 hospitals and found 45 Stroke Units distributed unequally among regions. The ratio of SU beds to residents ranged from 1/74,000 to 1/1,037,000 inhabitants; only the regions of Cantabria and Navarre met the target. Neurologists performed 3,237 intravenous thrombolysis procedures in 83 hospitals; thrombolysis procedures compared to the total of ischaemic strokes yielded percentages ranging from 0.3 to 33.7%. Hospitals without SUs showed varying levels of available resources. Neuro VIR is performed in every region except La Rioja, and VIR is only available on a 24h/7 d basis in 17 cities. Surgery for malignant MCA infarction is performed in 46 hospitals, and 5 have telemedicine. CONCLUSION: Stroke care has improved in terms of numbers of participating hospitals, the increased use of intravenous thrombolysis and endovascular procedures, and surgery for malignant MCA infarction. Implementation of SUs and telemedicine remain insufficient. The availability of diagnostic resources is good in most SUs and irregular in other hospitals. Regional governments should strive to ensure better care and territorial equality, which would achieve the EISNS objectives.

Can we improve the birth weight prediction? The effect of normal BMI using a multivariate model.

OBJECTIVE: The construction of a predictive model that improves the estimation of the fetal weight (EFW). STUDY DESIGN: a comparative, descriptive study. One hundred forty pregnant women were recruited at two-stage sample in health department in Spain. They were classified in four groups depending on the pre-gestational BMI. Fetal weight at term was estimated by ultrasound at 33-35 weeks (EFW40w) by one gynecologist. A regression model was created with the variables that reacted to the newborn's weight, symphysis-fundal height (SFH), EFW40w, gestational age (GA), ferritin level and cigarettes smoked. RESULTS: A multivariate model was created for the NW group to estimate the fetal weight (EFWme), resulting in R2=0.727 (p<0.001). The differences of the averages obtained between EFW40w and EFWme, with the newborn's weight were significant (p<0.001). EFWme underestimates birth weight by 0.07 g (mean error 0.53%), and EFW40w overestimates it by 300.89 g (mean error 10.12%). In order to evaluate the predictive model and verify the predictions we used the Bland-Altman analysis. The average error in estimating the birth weight with EFWme was 1.94% underestimating the result, whereas the ultrasound error overestimated the result 10.93%. CONCLUSION: The multivariate model created for the NW group improves the accuracy of the ultrasound.

Objectivo: construir un modelo predictivo que mejore la estimación del peso del recién nacido (PFE). Material y Métodos: Estudio observacional dónde 140 gestantes fueron estudiadas mediante un muestreo bietápico en un Departamento de Salud en España. Fueron clasificadas en cuatro grupos dependiendo del IMC pregestacional materno. El peso proyectado al nacer fue estimado por la ecografía realizada entre las 33-35 semanas de gestación (PP40s). Se construyó un modelo de regresión con las variables que se reaccionaban con el peso al nacer, altura uterina (AU), PP40s, edad gestacional (EG), nivel de ferritina y cigarillos consumidos. Resultados: Se construyó un modelo multivariante para el grupo Normo-peso para estimar el peso al nacer (PFm) obteniendo una R2=0,727 (p.

EFECTO DE LA INCLUSIÓN DE DIFERENTES FUENTES DE LÍPIDOS SOBRE PARÁMETROS PRODUCTIVOS Y COMPOSICIÓN PROXIMAL DEL FILETE DE TILAPIA NILÓTICA -Oreochromis niloticus- CULTIVADA EN JAULAS FLOTANTES / EFFECT OF THE INCLUSION OF DIFFERENT LIPID SOURCES ON GROWTH PERFORMANCE AND PROXIMATE COMPOSITION OF NILE TILAPIA FILLET -Oreochromis niloticus- REARED IN FLOATING CAGES

Para evaluar el efecto de la inclusión de diferentes fuentes de lípidos sobre el comportamiento productivo y la composición proximal del filete de tilapia nilótica Oreo-chromis niloticus, se formularon cuatro dietas con aceite de pescado (AP), aceite de palma (APL), semilla de chía (SC) o semilla de lino (SL). El experimento fue realizado durante 45 días en la represa de Betania (Huila, Colombia), en 20 jaulas flotantes, cada una con 504 peces con peso promedio de 557±16,87 g, distribuidos bajo un diseño experimental completamente al azar. Adicionalmente se llevó a cabo un estudio de presupuestos parciales, con el fin de verificar el margen bruto de ingreso parcial (MBIP) obtenido con las diferentes dietas. Se observaron diferencias significativas (P < 0,05) en el factor de conversión alimenticia (FCA) entre AP (1,19) y SL (1,54) y en la tasa de eficiencia proteica (TEP) para AP (3,64) al comparar con las demás dietas. Por su parte, la dieta que contenía SC generó el menor MBIP, seguido de SL, APL y AP. En la composición proximal de los filetes, únicamente se observaron diferencias significativas (P < 0,05) en el contenido de proteína cruda entre AP (18,23%) al compararlo con SL (19,17%). En conclusión, es posible utilizar AP, APL, SC o SL como fuentes de lípidos en las dietas, sin afectar la sobrevivencia, biomasa final, ganancia diaria de peso, consumo aparente de alimento, tasa específica de crecimiento e índice viscerosomático.

In order to evaluate the effect of inclusion of different lipid sources on growth performance and proximate composition of Nile tilapia Oreochromis niloticus fillet, four diets were manufactured with: fish oil (FO), palm oil (PO), chia seeds (CS) or flaxseeds (FS). The experiment was conducted for 45 days at Betania reservoir (Huila), in 20 floating completely randomized experimental design. In Addition, an economical partial budget analysis was run to establish the partial gross marginal income (PGMI) obtained with the different diets. Significant differences (P < 0,05) were observed in feed conversion ratio (FCR) between FO (1,19) and FS (1,54) and protein efficiency ratio (PER) among FO (3,64) and the other diets. The CS diet generated the lower IGMP followed by FS, PO and FO. In fillet proximal composition there were significant differences (P < 0,05) only in crude protein content, between FO (18,23%) compared with FS (19,17%). In conclusion it is possible to use FO, PO, CS or FS as lipids sources in the diet without affecting survival, final biomass, daily live weight gain, apparent food intake, specific growth rate and viscerosomatic index. cages, each one with 504 fish with mean live weight of 557 ± 16,87 g, distributed in a completely randomized experimental design.
