Relationship between fat-free mass and metabolic syndrome in obese females.

OBJECTIVE: A greater fat-free mass (FFM) could be negatively or positively associated with metabolic syndrome (MS). The objective of this work was to evaluate the relationship of FFM with MS, through three determinations; absolute FFM, relative to body weight FFM% and relative to squared height (FFMi). PATIENTS AND METHODS: We conducted a cross-sectional study on 1,008 obese Caucasian females. Fat-free mass index (FFMi) was calculated by dividing FFM by squared height [FFM (kg)/height (m2)]. Fat-free mass percentage (FFM%) was calculated (absolute FFM/body weight) x100. RESULTS: The odds ratio adjusted by age of having MS per tertiles were significantly higher in tertile 3 of FFM (OR=1.74, 95% CI=1.26-2.41; p=0.01) and FFMi (OR=3.38, 95% CI=2.42-3.72; p=0.001) and tertile 2 of FFM (OR=1.45, 95% CI=1.08-1.94; p=0.02) and FFMi (OR=2.37, 95% CI=1.75-3.20; p=0.01) compared with its reference (tertile-1). In contrast, odds ratio adjusted by age of having MS per tertiles were significantly lower in tertile-3 of FFM% (OR=0.29, 95% CI=0.20-0.41; p=0.01) and tertile- 2 of FFM% (OR=0.68, 95% CI=0.51-0.91; p=0.01) compared with its reference (tertile-1). CONCLUSIONS: The prevalence of MS relative to FFM varies depending on the method used to represent it.

Tratamiento a distancia de la insuficiencia cardiaca mediante el algoritmo HeartLogic. Registro RE-HEART / Remote heart failure management using the HeartLogic algorithm. RE-HEART registry

Introducción y objetivos HeartLogic es un algoritmo multiparamétrico incorporado a desfibriladores automáticos implantables (DAI). La alerta asociada predice descompensaciones de insuficiencia cardiaca (IC). Nuestro objetivo es analizar la asociación entre alertas y eventos clínicos bajo un protocolo de seguimiento común en un registro multicéntrico. Métodos Se evaluaron la fase 1 (investigadores ciegos al estado de la alerta) y las fases 2 y 3 (tras la activación de HeartLogic, según práctica local y un protocolo común respectivamente). Resultados Se incluyó a 288 pacientes en 15 centros. En fase 1, tras una media de observación de 10 meses, hubo 73 alertas (0,72 alertas/paciente-año), con 8 hospitalizaciones y 2 visitas a urgencias por IC (0,10 eventos/año-paciente). No hubo hospitalizaciones fuera del periodo de alerta. Las fases activas tuvieron una media de seguimiento de 16 (IC95%, 15-22) meses, con 277 alertas (0,89 alertas/año-paciente); 33 se asociaron con hospitalizaciones o muerte por IC, 46 con descompensaciones menores y 78 con otros eventos. La tasa de alertas inexplicables fue 0,39/año-paciente. Fuera del estado de alerta solo hubo una hospitalización y una descompensación menor. La mayoría de las alertas (el 82% en fase 2 y el 81% en fase 3; p=0,861) se gestionaron a distancia. La mediana de NT-proBNP fue superior en estado de alerta que fuera de él (7.378 frente a 1.210 pg/ml; p <0,001). Conclusiones El índice HeartLogic se asoció con descompensaciones de IC y otros eventos relevantes, con baja tasa de alertas inexplicables. Un protocolo estandarizado permitió detectar y actuar a distancia con seguridad sobre las alertas (AU)

Introduction and objectives HeartLogic is a multiparametric algorithm incorporated into implantable cardioverter-defibrillators (ICD). The associated alerts predict impending heart failure (HF) decompensations. Our objective was to analyze the association between alerts and clinical events and to describe the implementation of a protocol for remote management in a multicenter registry. Methods We evaluated study phase 1 (the investigators were blinded to the alert state) and phases 2 and 3 (after HeartLogic activation, managed as per local practice and with a standardized protocol, respectively). Results We included 288 patients from 15 centers. In phase 1, the median observation period was 10 months and there were 73 alerts (0.72 alerts/patient-y), with 8 hospitalizations and 2 emergency room admissions for HF (0.10 events/patient-y). There were no HF hospitalizations outside the alert period. In the active phases, the median follow-up was 16 (95%CI, 15-22) months and there were 277 alerts (0.89 alerts/patient-y); 33 were associated with HF hospitalizations or HF death (n=6), 46 with minor decompensations, and 78 with other events. The unexplained alert rate was 0.39 alerts/patient-y. Outside the alert state, there was only 1 HF hospitalization and 1 minor HF decompensation. Most alerts (82% in phase 2 and 81% in phase 3; P=.861) were remotely managed. The median NT-proBNP value was higher within than outside the alert state (7378 vs 1210 pg/mL; P <.001). Conclusions The HeartLogic index was frequently associated with HF-related events and other clinically relevant situations, with a low rate of unexplained events. A standardized protocol allowed alerts to be safely and remotely detected and appropriate action to be taken on them (AU)

Correlation of the Phase Angle with Muscle Ultrasound and Quality of Life in Obese Females.

Introduction: Phase angle (PhA) has been suggested to be an indicator of body cell mass and nutritional status. Clinically, the phase angle supposedly reflects body cell mass and cell membrane function, and the higher the phase angle, the better is the cell function. Muscle ultrasound (US) is an emerging nutritional assessment technique. Objective: The aim of this study was to investigate the usefulness and correlation of PhA with muscle US of quadriceps rectus femoris (QRF) in obese female subjects and the relationship with quality of life and physical performance. Material and Methods. In a total of healthy 50 obese female patients, anthropometric data by BIA, muscle mass by ultrasound at the QRF level, analytical determination, blood pressure, and quality of life were measured. Physical performance was assessed, too. Results: In total, 50 female obese patients were included with a mean age of 45.9 ± 2.4 years. The mean body mass index was 32.1 ± 1.6 kg/m2 with a mean weight of 83.5 ± 14.6 kg. Correlation analysis showed a positive correlation of PhA with all US parameters corrected by squared height (anteroposterior muscle thickness, circumference, cross-sectional area, and Echo-intensity). The correlation analysis of biochemical parameters with PhA showed a positive correlation with serum albumin and total protein levels. Physical activity and vitality scores of SF36 were correlated with PhA. Finally, PhA was positive correlated with physical performance, doing push-ups in 30 seconds (r =0.42; p =0.03) and doing squats in 30 seconds (r =0.54; p =0.02), without correlation with the time of 1.5 km walk. Conclusion: PhA was correlated with muscle area, muscle circumference, muscle echo intensity, serum protein, quality of life SF-36, and strength physical performance.

RS9939609 FTO gene variant modified weight loss and insulin resistance after a partial meal-replacement hypocaloric diet.

OBJECTIVE: Some studies have demonstrated that the allele A of FTO rs9939609 is related to both higher waist circumference and body mass index. Subsequently, some designs related biochemical variables and body weight changes with this genetic variant. We decide to analyze the effects of rs9939609 genetic variant of FTO gene on metabolic parameters and weight loss secondary to partial meal replacements hypocaloric diets (pMRHDs) in obese subjects. PATIENTS AND METHODS: This was a non-randomized, single-treatment study with a formula-diet in 44 obese subjects. The patients received nutritional education and a pMRHDs with two intakes of normocaloric hyperproteic formula during 12 weeks. Anthropometric parameters and biochemical profiles were measured at basal time and after 12 weeks. The variant of FTO gene rs9939609 was determined. RESULTS: Genotype distribution (n=44) was (16 TT (36.4%), 17 TA (38.6%) and 11 AA (25.0%)). After the pMRHD, body weight, body mass index (BMI), fat mass, waist circumference, serum leptin levels and systolic blood pressure improved in both genotypes without statistical differences in both branches. After dietary intervention with pMRHD, subjects with A allele showed a significant improvement in total cholesterol levels (TT vs. TA+AA) (-3.8±1.4 md/dL vs. -12.6±1.7 mg/dl: p=0.01), LDL-cholesterol (-0.2±1.5 md/dL vs. -10.5±1.9 mg/dl: p=0.02), insulin levels (-1.9±0.2 mU/L vs. -3.8±0.3 mU/L: p=0.02) and HOMA-IR (-0.6±0.2 units vs. -1.1±0.1 units: p=0.01). CONCLUSIONS: Our data suggest that the genetic variant (rs9939609) of FTO gene showed better improvement of LDL-cholesterol, insulin and HOMA-IR in subjects with A allele.

Prospective comparison among three intrarectal anesthetic treatments combined with periprostatic nerve block during transrectal ultrasonography-guided prostate biopsy.

BACKGROUND: Recent trends in prostate biopsy analgesia suggest a combination anesthetic to provide better pain relief than periprostatic nerve block (PPNB) alone. This study aimed to demonstrate the efficacy and safety of three intrarectal local anesthesia (IRLA) combined with PPNB in patients undergoing transrectal ultrasonography (TRUS)-guided prostate biopsy. METHODS: In this prospective, randomized study, 120 prostate biopsy patients were equally divided into four IRLA groups: group 1 (placebo) received simple lubrication; group 2 received 2% lidocaine gel; group 3 received 100 mg indomethacin suppository and group 4 received 5% prilocaine/lidocaine (EMLA) cream. PPNB with 2% lidocaine was applied in all groups. A ten-point visual analog scale evaluated both pain associated with the probe insertion and pain associated with prostate sampling. Adverse effects or complications due to anesthesia during and after the procedure were documented. RESULTS: Compared with group 1, groups 3 and 4 had significantly lower pain scores at both probe insertion and prostate sampling while group 2 showed no significant differences at both pain scores. Moreover, group 4 showed significantly lower pain scores at probe insertion compared to group 3, while no significant difference was observed at prostate sampling. Mild complications were observed in all groups with no significant difference in the incidence of complications between groups. CONCLUSION: Intrarectal application of EMLA cream is a more efficient pain reduction than either 2% lidocaine gel or 100 mg indomethacin suppository when applied combined with PPNB. This combination represents an effective option of pain relief for patients undergoing TRUS-guided prostate biopsy.

[Multidisciplinary meeting on application techniques for restitution of synovial fluid in patients with knee arthritis: update]. / Reunión multidisciplinaria sobre técnicas de aplicación para la restitución de fluido sinovial en pacientes con artritis de rodilla: puesta al día.

In the degradation of articular cartilage, functional limitation and pain cardinal signs of osteoarthritis underlies, as a central factor, the quantitative and qualitative alteration of hyaluronic acid, the main component of synovial fluid and cartilage, in a pathophysiological process influenced by a wide variety of risk factors whose impact complicates the disease and radically reduces the quality of life of the patient. Conventional pharmacological management for osteoarthritis is often insufficient. Fortunately, in our days, there are viscosupplements capable of improving, replacing and promoting the endogenous production of degraded hyaluronic acid in osteoarthritis. The use of these compounds requires the adherence to a set of specific techniques, designed for the correct intra-articular infiltration of the viscosupplement without the need to inflict an additional traumatic load on the patient; these techniques with special reference to the patient affected by knee osteoarthritis (gonarthritis) are described in this article, which also highlights the criteria for choosing the ideal viscosupplement, the one most similar to hyaluronic acid native in healthy young people, and one whose therapeutic use reports greater clinical benefits in the short and long term.

En la degradación del cartílago articular, la limitación funcional y el dolor se asocian a la alteración cuantitativa y cualitativa del ácido hialurónico en un proceso fisiopatológico sobre el que influye una amplia variedad de factores cuyo impacto agrava la enfermedad y disminuye la calidad de vida del paciente. El manejo farmacológico convencional para la osteoartritis es a menudo insuficiente. Por fortuna, en el mundo actual se cuenta con viscosuplementos capaces de mejorar, restituir y promover la producción endógena del ácido hialurónico degradado en los cuadros de osteoartritis. El uso de estos compuestos exige el apego a un conjunto de técnicas específicas, diseñadas para la correcta infiltración intraarticular del viscosuplemento sin necesidad de infligir una carga traumática adicional al paciente; estas técnicas con referencia especial al paciente afectado por la osteoartritis de rodilla (gonartritis) se describen en el presente artículo, en el que además se destacan los criterios para la elección del viscosuplemento idóneo, el más semejante al ácido hialurónico nativo de personas jóvenes y sanas y aquel cuyo uso terapéutico reporta mayores beneficios clínicos a corto y a largo plazo.

Surgical treatment of large incisional hernias with intraperitoneal composite mesh: a cohort study.

PURPOSE: Patients with large incisional hernias have significant morbidity and their management is a challenge for the surgical team because of the large abdominal wall involvement. The choice of surgical technique is still controversial. The purpose of this study is to analyze the predictive factors for recurrence after intraperitoneal mesh repair in patients with large incisional hernias. METHODS: A retrospective cohort observational study with a prospectively collected database was performed in the Hospital Clinico San Carlos (Madrid, Spain). All consecutive patients operated on from January 2009 to December 2014 with incisional hernia of 10 or more centimeters in its transverse diameter were included. An intraperitoneal repair with a composite mesh fixed with discontinuous absorbable suture and fibrin sealant was performed. Demographic data, comorbidities, and early and long term outcomes were analyzed. The primary outcome was the presence of recurrence. RESULTS: One hundred and twenty patients were included. Mean age was 63.3 years (SD 12.9) and sex ratio was 1.4:1. Seventy-two patients (60%) were ASA III-IV. Forty-five patients (37.5%) had recurrent ventral hernias. Mean defect size was 14.7 cm (SD 3.21) of width. Overall postoperative morbidity rate was 25%. Median hospital stay was 6 days (IQR 4-8). Recurrence rate was 8.3%, after a median follow-up of 16 months (IQR 10-25). Multivariate analysis showed significant association between ASA III-IV, use of Composix Kugel™ mesh, superficial surgical site infection, and the presence of recurrence. CONCLUSIONS: The recurrence rate after intraperitoneal mesh repair in patients with large incisional hernias might be associated with ASA III-IV, use of Composix Kugel™ mesh, and superficial surgical site infection.

Robot-assisted laparoscopic partial nephrectomy with hydrodissection. / Nefrectomía parcial laparoscópica asistida por robot con hidrodisección.

INTRODUCTION: Nephron-sparing surgery is reporting satisfactory oncological results, with improved quality of life. The laparoscopic approach is technically complex and requires advanced skills; however, the use of robotic systems facilitates the transition to this procedure. With improved strategies for diagnosis and follow-up, as well as ablative technologies, the role of partial nephrectomy continuous to evolve. The use of water-jet technology to dissect and resect organs helps create anatomical planes in a relatively blood-free field, which improves vision and does not cause heat damage. MATERIAL AND METHODS: We present the case of a patient with an incidental diagnosis of a complex right renal cyst managed with robot-assisted laparoscopic partial nephrectomy using hydrodissection for tumour resection. RESULTS: The surgery was performed with 2 robotic arms. Four ports were routinely placed, the colon was mobilised, and the tumour was dissected. Tumour delimitation was performed with laparoscopic ultrasound, and the renal artery was clamped. We then performed the tumour resection assisted by a laparoscopic water-jet applicator, operated by the assistant through an auxiliary port. The renal parenchyma was reconstructed in 2 planes, without knots, and the arterial clamp was withdrawn at 23minutes. The resection margins were negative. CONCLUSIONS: The use of water-jet technology to assist with the renal tumour resection during minimally invasive nephron-sparing surgery facilitates the dissection, making it more fluid and atraumatic. Simultaneously, the technique provides a clean surgical field, which improves visibility. This procedure can help decrease ischaemia times, thereby positively affecting the patient's evolution without compromising the oncological results.

Surgical technique for en bloc transurethral resection of bladder tumour with a Hybrid Knife(®). / Técnica quirúrgica de la resección transuretral de tumor vesical en bloque con Hybrid Knife(®).

BACKGROUND: Bladder cancer is the second most common malignancy of the urinary tract and the 9th worldwide. Latin American has an incidence of 5.6 per 100,000 inhabitants per year. Seventy-five percent of newly diagnosed cases are nonmuscle invasive bladder cancer, and 25% of cases present as muscle invasive. The mainstay of treatment for nonmuscle invasive bladder cancer is loop transurethral resection. In 2013, the group led by Dr Mundhenk of the University Hospital of Tübingen, Germany, was the first to describe the Hybrid Knife(®) equipment for performing en bloc bladder tumour resection, with favourable functional and oncological results. OBJECTIVE: To describe the surgical technique of en bloc bladder tumour resection with a Hybrid Knife(®) as an alternative treatment for nonmuscle invasive bladder tumours. MATERIAL AND METHODS: A male patient was diagnosed by urotomography and urethrocystoscopy with a bladder tumour measuring 2×1cm on the floor. En bloc transurethral resection of the bladder tumour was performed with a Hybrid Knife(®). RESULTS: Surgery was performed for 35min, with 70 watts for cutting and 50 watts for coagulation, resecting and evacuating en bloc the bladder tumour, which macroscopically included the muscle layer of the bladder. There were no complications. CONCLUSION: The technique of en bloc bladder tumour resection with Hybrid Knife(®) is an effective alternative to bipolar loop transurethral resection. Resection with a Hybrid Knife(®) is a procedure with little bleeding and good surgical vision and minimises the risk of bladder perforation and tumour implants. The procedure facilitates determining the positivity of the neoplastic process, vascular infiltration and bladder muscle invasion in the histopathology study.

Effects of a High-Protein/Low-Carbohydrate versus a Standard Hypocaloric Diet on Weight and Cardiovascular Risk Factors during 9 Months: Role of a Genetic Variation in the Cannabinoid Receptor Gene (CNR1) (G1359A Polymorphism).

OBJECTIVE: We decided to investigate the role of this polymorphism on cardiovascular risk factors and weight loss secondary to a high-protein/low-carbohydrate vs. a standard hypocaloric diet (1,000 kcal/day) over a period of 9 months. MATERIAL AND METHODS: A nutritional evaluation was performed at the beginning and at the end of a 9-month period in which subjects received 1 of 2 diets (diet HP: high protein/low carbohydrate vs. S: standard diet). RESULTS: One hundred and four patients (54.7%) had the genotype G1359G and 86 (45.3%) patients had G1359A (77 patients, 25.8%) or A1359A (9 patients, 3.7%) (A-allele-carriers). In subjects with both genotypes, the body mass index, weight, fat mass, waist circumference and systolic blood pressures decreased with both diets. After the diet type HP and in subjects with both genotypes, the glucose, leptin, total cholesterol, LDL-cholesterol, insulin and HOMA-R levels decreased. After diet S and in all subjects, the total cholesterol, LDL cholesterol and leptin levels decreased, too. CONCLUSION: Our interventional study didn't show a relationship between the rs1049353 CNR-1 polymorphism and body weight response after two different hypocaloric (low carbohydrate/high protein vs. standard) diets over a period of 9 months. However, a low-carbohydrate/high-protein diet for 9 months improved glucose metabolism in subjects with both genotypes.
