The Role of Adiponectin in the Resolution of Male-Obesity-Associated Secondary Hypogonadism after Metabolic Surgery and Its Impact on Cardiovascular Risk.

Male-obesity-associated secondary hypogonadism (MOSH) is a very prevalent entity that may resolve after marked weight loss. Adiponectin (APN) is an adipokine with anti-inflammatory properties that regulates metabolism. Low-circulating APN is associated with obesity, diabetes, and cardiovascular risk, along with circulating testosterone. We aimed to evaluate APN changes in men with MOSH (low circulating free testosterone (FT) with low or normal gonadotropins) and without it after metabolic surgery. We look for their possible association with cardiovascular risk measured by carotid intima-media thickness (cIMT). We included 60 men (20 submitted to lifestyle modification, 20 to sleeve gastrectomy, and 20 to gastric bypass) evaluated at baseline and 6 months after. The increase in APN at follow-up was reduction in patients with persistent MOSH (n = 10) vs. those without MOSH (n = 30) and MOSH resolution (n = 20), and the former did not achieve a decrease in cIMT. The increase in APN correlated positively with FT (r = 0.320, p = 0.013) and inversely with cIMT (r = -0.283, p = 0.028). FT inversely correlated with cIMT (r = -0.269, p = 0.038). In conclusion, men without MOSH or with MOSH resolution showed a high increase in APN after weight loss with beneficial effects on cIMT. Those without MOSH resolution failed to attain these effects.

Experiencia inicial del tratamiento de la carcinomatosis peritoneal irresecable con PIPAC / Initial Single-center Experience of PIPAC in Patients With Unresectable Peritoneal Metastasis

Introducción: La carcinomatosis peritoneal se asocia a un mal pronóstico y las opciones terapéuticas son limitadas. El desarrollo de la quimioterapia intraperitoneal presurizada en aerosol (PIPAC) ofrece una alternativa de tratamiento paliativo para estos pacientes con una baja tasa de morbimortalidad. Nuestro objetivo es evaluar la implantación y la experiencia inicial de PIPAC para el tratamiento de la carcinomatosis peritoneal irresecable en nuestro centro. Material y métodos: Realizamos un estudio prospectivo incluyendo todos los pacientes a los que se les realizó PIPAC entre enero de 2019 y febrero de 2020 en nuestro hospital. Se recogieron: el origen del tumor primario, el volumen de ascitis, la extensión de la carcinomatosis peritoneal, el régimen de quimioterapia aplicada, el tiempo quirúrgico, las complicaciones postoperatorias, la estancia hospitalaria y la mortalidad. Resultados: Analizamos 9 PIPAC realizadas en 5pacientes con carcinomatosis peritoneal de origen gástrico, ovárico y neoplasia mucinosa apendicular. La tasa de acceso a la cavidad peritoneal fue del 100%. El PCI medio fue 27,6 (24-35). El tiempo quirúrgico medio fue de 93min (70-125). En nuestra serie solo hubo una complicación Clavien-DindoII (1/9 procedimientos). La estancia hospitalaria media fue de 2días (1-4). La mortalidad fue del 0%. Conclusión: La implantación de PIPAC en nuestro centro se ha llevado a cabo con seguridad, pudiendo afirmar que es una técnica reproducible y con una baja tasa de morbimortalidad en nuestra experiencia inicial.

Circulating Zinc and Copper Levels are Associated with Sperm Quality in Obese Men after Metabolic Surgery: A Pilot Study.

(1) Background: Inadequate levels of several trace elements and vitamins may impair spermatogenesis in men. Although weight loss after metabolic surgery normalizes male reproductive hormones, sperm quality seems to not improve. We hypothesized that circulating concentrations of zinc, copper and other trace elements and vitamins might be involved. (2) Methods: We studied 20 men submitted to metabolic surgery at baseline and after two years. Hormone profiles, serum trace elements and vitamins were studied together with sperm analysis. (3) Results: At follow-up, serum testosterone, follicle-stimulating hormone and inhibin B concentrations increased showing a beneficial hormonal response for spermatogenesis. Conversely, serum copper, zinc and ferritin showed a decline after surgery. In total, 33% of men showed zinc deficiency, 27% copper deficiency and 20% iron deficiency, among others. Sperm analysis showed that all revaluated patients had at least one abnormal parameter. Serum zinc concentrations showed a positive correlation with progressive motility (r = 0.577, p = 0.031), and serum ferritin a positive correlation with sperm volume (ρ = 0.535, p = 0.049). Serum copper showed a weak and near significant correlation with motility (r = 0.115, p = 0.051). (4) Conclusions: The lack of improvement in sperm quality in obese men after metabolic surgery may be related to nutrient malabsorption, especially zinc, copper and iron.

Sleeve Gastrectomy and Gastric Bypass Decrease the Carotid Intima-Media Thickness in Obese Men: Association with Weight Loss, Cardiovascular Risk Factors, and Circulating Testosterone.

BACKGROUND: Obesity surgery has shown to decrease the carotid intima-media thickness (IMT), but studies that compare different surgical techniques are scarce, especially in men. OBJECTIVE: To evaluate the changes in IMT in men after laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) and its association with circulating testosterone. SETTING: Academic Hospital. METHODS: We studied 40 men with severe obesity, of whom 20 were submitted to laparoscopic RYGB and 20 to SG. Twenty control men matched for age and degree of obesity were also included. Both patients and controls were evaluated at baseline and 6 months after surgery or conventional treatment with diet and exercise, respectively. RESULTS: The mean carotid IMT decreased after surgery irrespective of the surgical technique whereas no changes were observed in the control men submitted to conventional therapy (Wilks' λ = 0.745, P < 0.001 for the interaction, P < 0.001 for RYGB vs. controls, P = 0.001 for SG vs. controls, P = 0.999 for RYGB vs. SG). The decrease in the carotid IMT correlated with the increase in total testosterone (r = 0.428, P = 0.010) and lost BMI (r = 0.486, P < 0.001). Multivariate linear regression retained only the decrease in BMI (ß = 0.378, P = 0.003) after adjustment (R2 = 0.245, F = 9.229, P = 0.001). CONCLUSION: Both RYGB and SG decrease carotid IMT in men with obesity compared with conventional treatment with diet and exercise.

¿Permiten la citología, el genotipado y la anoscopia de alta resolución establecer un protocolo para la detección precoz del carcinoma epidermoide de canal anal en población de riesgo? / Do cytology, genotyping, and high resolution anoscopy allow to establish a protocol for early detection of squamous cell carcinoma of the anal canal in risk population?

Introducción: El cáncer anal ha experimentado un aumento de incidencia en los últimos años. Está mediado por el VPH y precedido de cambios precancerosos planteando la posibilidad de dirigir los esfuerzos preventivos hacia los grupos de alto riesgo. Sigue siendo controvertida la indicación de cribado y los métodos de detección ideales. Objetivo: Validar las pruebas de cribado implementadas en la actualidad comparadas con la biopsia como "gold standard". Material y Métodos: Estudio transversal con recogida de datos prospectiva, en una cohorte de hombres VIH+ que tienen sexo con hombres, pertenecientes al Hospital Gregorio Marañón e Infanta Leonor en un periodo de 2 años. Resultados: Se seleccionaron 179 pacientes con 286 visitas a la consulta de screening en las que se llevaron a cabo 3 pruebas de cribado en paralelo (citología anal, genotipado del VPH y anoscopia de alta resolución (AAR) con toma de biopsia dirigida sobre zona sospechosa o aleatoria). La sensibilidad y especificidad para la detección de displasia de alto grado y cáncer y su grado de concordancia con la biopsia fue la siguiente: citología 3,23%/94,43% (k: 0,03), genotipado de VPH de alto riesgo 90,32%/27,45% (k: 0,05), AAR 32,26%/87,45 (k: 0, 17) siendo el rendimiento diagnóstico de las tres pruebas muy bajo. Conclusión: La citología presenta un rendimiento diagnóstico muy bajo comparado con el genotipado que representa el mayor. A la luz de nuestros resultados, los protocolos clínicos tal y como vienen desarrollándose en la actualidad deberían de ser abandonados.

Introduction: The incidence of anal cancer has increased in recent years. It is mediated by HPV and preceded by precancerous changes, raising the possibility of directing preventive efforts towards high-risk groups. The indication of screening remains controversial and which methods would be the ideal ones. Objective: To validate the screening tests established actually, comparing it with the biopsy considered as the "gold standard". Materials and Methods: A cross-sectional study was performed, with prospective data collection in a cohort of VIH+ patients, who have male homosexual anal relations, belonging to Gregorio Marañón and Infanta Leonor Hospitals in a period of 2 years. Results: A total of 179 patients were selected with 286 visits to the screening Outpatient Clinic in which 3 parallel screening tests were performed (anal cytology, HPV genotyping and high resolution anoscopy (AAR) with a biopsy directed on a suspicious or random area). The sensitivity and specificity for the detection of high-grade dysplasia and cancer and their degree of agreement with the biopsy was as follows: cytology 3.23%/94.43% (k: 0.03), high HPV genotyping. risk 90.32%/27.45% (k: 0.05), AAR 32.26%/87.45 (k: 0, 17), the diagnostic accuracy of the three tests being very low. Conclusion: Cytology shows a very low diagnostic accuracy compared to the genotype that represents the highest one. In light of our results, clinical protocols as they are currently being developed should be abandoned.

Factores predictivos de mortalidad en la gangrena de Fournier: serie de 59 casos / Predictive factors for mortality in Fournier’ gangrene: A serie of 59 cases

OBJETIVOS: La gangrena de Fournier (GF) es la fascitis necrosante del periné y área genital que presenta una elevada mortalidad. El objetivo es analizar los factores pronósticos de mortalidad, creación de una nueva escala predictiva de mortalidad y compararla con las ya validadas en los pacientes diagnosticados de GF en nuestro Servicio de Urgencias. MÉTODOS: Estudio analítico, retrospectivo entre 1998 y 2012. RESULTADOS: De los 59 casos, 44 sobrevivieron (74%) (S) y 15 fallecieron (26%) (E). Se encontraron diferencias significativas en la vasculopatía periférica (S 5 [11%]; E 6 [40%]; p = 0,023), hemoglobina (S 13; E 11; p = 0,014), hematocrito (S 37; E 31,4; p = 0,009), leucocitos (S 17.400; E 23.800; p = 0,023), urea (S 58; E 102; p < 0,001), creatinina (S 1,1; E 1,9; p = 0,032), potasio (S 3,7; E 4,4; p = 0,012) y fosfatasa alcalina (S 92; E 133; p = 0,014). Escalas predictivas: índice de Charlson (S 1; E 4; p = 0,013), criterios de sepsis grave (S 16 [36%]; E 13 [86%]; p = 0,001), Fournier's gangrene severity index score (FGSIS) (S 4; E 7; p = 0,002) y Uludag Fournier's Gangrene Severity Index (UFGSI) (S 9; E 13; p = 0,004). Los factores predictores independientes fueron la vasculopatía periférica, el potasio sérico y criterios de sepsis grave, creando un modelo con área bajo la curva de 0,850 (0,760-0,973) superior al FGSIS (0,746 [0,601-0,981]) y al UFGSI (0,760 [0,617-0,904]). CONCLUSIONES: La GF presentó una tasa de mortalidad elevada cuyos factores predictores independientes fueron la vasculopatía periférica, el potasio sérico y criterios de sepsis grave, creando un modelo con una capacidad discriminativa superior al resto

AIMS: Fournier's gangrene (FG) is the necrotizing fasciitis of the perineum and genital area and presents a high mortality rate. The aim was to assess prognostic factors for mortality, create a new mortality predictive scale and compare it with previously published scales in patients diagnosed with FG in our Emergency Department. METHODS: Retrospective analysis study between 1998 and 2012. RESULTS: Of the 59 patients, 44 survived (74%) (S) and 15 died (26%) (D). Significant differences were found in peripheral vasculopathy (S 5 [11%]; D 6 [40%]; P = .023), hemoglobin (S 13; D 11; P = .014), hematocrit (S 37; D 31.4; P = .009), white blood cells (S 17,400; D 23,800; P = .023), serum urea (S 58; D 102; P < .001), creatinine (S 1.1; D 1.9; P = .032), potassium (S 3.7; D 4.4; P = .012) and alkaline phosphatase (S 92; D 133; P = .014). Predictive scores: Charlson index (S 1; D 4; P = .013), severe sepsis criteria (S 16 [36%]; D 13 [86%]; P = .001), Fournier's gangrene severity index score (FGSIS) (S 4; D 7; P = .002) and Uludag Fournier's Gangrene Severity Index (UFGSI) (S 9; D 13; P = .004). Independent predictive factors were peripheral vasculopathy, serum potassium and severe sepsis criteria, and a model was created with an area under the ROC curve of 0.850 (0.760-0.973), higher than FGSIS (0.746 [0.601-0.981]) and UFGSI (0.760 [0.617-0.904]). CONCLUSIONS: FG showed a high mortality rate. Independent predictive factors were peripheral vasculopathy, potassium and severe sepsis criteria creating a predictive model that performed better than those previously described

Linfoma no Hodgkin suprarrenal primario / Primary Non Hodgkin´s Lymphoma of the Adrenal Gland

El linfoma no Hodgkin primario de la glándula suprarrenal es una patología muy poco común. Su diagnóstico inicial es difícil siendo este histológico. El linfoma B difuso de células grandes es el tipo histológico más frecuente. Se presenta el caso mujer de 62 años a la que se le realiza tomografía axial computarizada abdominal que muestra una masa de 18 cms dependiente de la glándula suprarrenal y con características de carcinoma. Se realiza exéresis de la tumoración, siendo la anatomía patológica linfoma difuso de célula grande B. Este tipo de linfoma tiene mal pronóstico describiéndose supervivencias medias en torno a los 13 meses. No existe un régimen terapéutico bien definido; aunque el tratamiento más aceptado es el esquema R-CHOP. El papel de la radioterapia y de la exéresis tumoral no está claramente establecido. El linfoma suprarrenal primario debe tenerse en cuenta en el diagnóstico diferencial de pacientes que presentan una masa suprarrenal. Ante la sospecha de esta patología es preferible realizar una biopsia con aguja guiada por prueba de imagen para evitar una intervención quirúrgica innecesaria(AU)

Primary non- Hodgkin`s lymphoma of the adrenal gland is very rare. Its initial diagnosis is difficult and needs to be histological. Diffuse large B- cell lymphoma is the most common histological type. This is the report of a 62 years old woman, who was performed abdominal tomography to disclose a 18 cm tumor in the adrenal gland with carcinoma characteristics. The tumor was removed and the final pathologic diagnosis was diffuse large B-cell lymphoma. This type of lymphoma has poor prognosis since the average survival rates are roughly 13 months. There is no well-defined therapeutic regimen, although the most widely accepted treatment is R-CHOP scheme. The roles of radiotherapy and tumor resection are not clearly established. Primary adrenal lymphoma should be considered in the differential diagnosis of patients presenting with an adrenal mass. When this condition is suspected, then it is advisable to perform a imaging-guided needle biopsy to avoid unnecessary surgery(AU)
