RESUMO
BACKGROUND: The long-standing underrepresentation of women in leadership positions in medicine is well-known, but poorly documented globally. There is some evidence of the gender gap in academia, medical society leadership, or specific problems in some specialties. However, there are no investigations analyzing all medical specialties together and reporting the glass ceiling from a 360º perspective that includes positions in academia, research, professional organizations, and clinical activity. Additionally, the majority of studies have a US perspective, and we wonder if the perspective of a European country might be different. The WOmen in MEDicine in Spain (WOMEDS) project ( https://womeds.es ) aims to describe and characterize, in a systematic and detailed way, the gender bias in the medical profession in Spain in order to monitor its evolution over time and contribute to prioritizing gender policies. METHODS: We retrieved data for the calendar years 2019-2021 from several sources and selected surveys. We built four groups of indicators to describe leadership positions in the medical profession: (i) leadership in healthcare according to specialty and region; (ii) leadership in scientific and professional bodies; (iii) academic career; and (iv) leadership in clinical research activity. As a summary measure, we reported the women ratios, calculated as the percentage of women in specific top positions divided by the percentage of women in the relevant population. RESULTS: We found gender inequity in leadership positions in all four settings. During the observed period, only 27.6% of the heads of departments in hospitals were women compared to 61.1% of women in medical staff. Ten of the 46 medical societies grouped in the Spanish Federation of Medical Societies (FACME) (21.7%) had a women president at some point during the study period, and only 4 annual congresses had ratios of women speakers higher than 1. Women were over-represented in the lower positions and underrepresented in the top academic ones. Only 26% and 27%, respectively, of the heads of departments and deans were women. The applications for public funding for research projects are led by women only in 45% of the cases, and the budget granted to women in public calls was 24.3% lower than that of men. CONCLUSION: In all the areas analyzed, the leadership positions are still mostly occupied by men despite the feminization of medicine in Spain. The severe gender inequity found calls for urgent interventions within a defined time horizon. Such measures must concern all levels, from national or regional regulation to changes in organizational culture or incentives in specific organizations.
RESUMEN EN ESPAÑOL: ANTECEDENTES: La prolongada infrarrepresentación de las mujeres en los puestos de liderazgo en medicina es bien conocida, pero está poco documentada de forma global. Hay evidencia sobre la brecha de género en la universidad, en el liderazgo en sociedades médicas o en determinadas especialidades. Sin embargo, no hay investigaciones que analicen el techo de cristal de cada una de las especialidades médicas desde una perspectiva 360º que incluya el liderazgo en la universidad, en la investigación con fondos públicos, en la representación en sociedades científicas y colegios profesionales y en la actividad clínica. Además, la mayoría de los estudios tienen una perspectiva estadounidense y nos preguntamos si la perspectiva de un país europeo podría ser diferente. El proyecto Mujeres en Medicina en España (WOMEDS) ( https://womeds.es ) tiene como objetivo describir y caracterizar de forma sistemática y detallada sesgo de género en la profesión médica en España, para monitorizar su evolución en el tiempo y contribuir a priorizar las políticas de género. MéTODOS: Construimos cuatro grupos de indicadores sobre liderazgo de mujeres médicos: (i) en la asistencia sanitaria; (ii) en las organizaciones científicas y profesionales; (iii) carrera académica, y; and (iv) l en la investigación basándonos en datos públicos y resultados de encuestas propias s referidas a los años 20192021. Como medida de análisis, calculamos los ratios de mujeres, definidos como el porcentaje de mujeres en puestos altos específicos dividido por el porcentaje de mujeres en la población relevante. RESULTADOS: Encontramos un sesgo de género en los cuatro ámbitos. Durante el periodo observado, solo el 27.6% de los jefes de servicio de los hospitales eran mujeres, frente al 61.1% de mujeres en la plantilla. Diez de las 46 sociedades médicas agrupadas en la Federación de Asociaciones Científico Médicas Españolas (FACME) (21.7%) tuvieron una mujer como presidente en algún momento del periodo de estudio y sólo 4 congresos anuales tenían ratios de mujeres ponentes superiores a 1. Las mujeres estaban sobrerepresentadas en los cargos inferiores e infrarrepresentadas en los cargos académicos superiores. Sólo el 26% y el 27%, respectivamente, de los jefes de departamento y decanos eran mujeres. La solicitud de proyectos de investigación con financiación pública fue liderada por mujeres en un 45% de los casos y la financiación media de los proyectos concedidos a las mujeres fue un 24.3% inferior a la de los hombres. CONCLUSIóN: En todos los ámbitos analizados, las posiciones de liderazgo siguen siendo mayoritariamente ocupada por varones a pesar de la feminización de la medicina. Para cambiar esto, será necesario tomar medidas, tanto regulatorias -a nivel nacional y nacional regional como promover cambios en la cultura organizativa o en los incentivos en organizaciones concretas.

BACKGROUND: the ideal clinical profile of patients or fistula features for fistula laser closure (FiLaC®) technique remain to be established. The aim of this study was to analyze clinical outcomes and the safety profile of FiLaC® in search for an ideal setting for this technique. METHODS: a retrospective observational study was performed from a prospective database including all consecutive patients who underwent surgery for anal fistula (AF) with FiLaC® in the coloproctology unit of a tertiary referral center, between October 2015 and December 2021. The FiLaC® procedure was offered to AF patients who were considered to be at risk of fecal incontinence. Fistulas were described according to Parks' classification and categorized as complex or simple according to the American Gastroenterological Association (AGA) guidelines. Healing was defined by the closure of the internal and external openings for at least six months. Predictive factors of AF healing were investigated. RESULTS: a total of 36 patients were included, with a mean age of 48 ± 13.9 years. Twenty patients (55.6 %) were male and 13 patients (36 %) had Crohn's disease (CD). Fourteen patients (38.8 %) had a complex fistula. The primary and secondary healing rates were 55.6 % and 91.7 %, respectively, during a median follow-up time of 12 months (IQR 7-29). No fecal continence impairment was registered in any case. The proportion of patients with primary healing was significantly higher in CD patients (76.9 % vs 43.5 %, p = 0.048). CONCLUSIONS: FiLaC® is a sphincter-preserving procedure with an excellent safety profile and reasonable success rate despite of the strict patient selection. This technique may be attractive for patients with CD due to its higher primary healing rate.

Introduction: The SARS-CoV-2 pandemic has affected training opportunities for healthcare professionals partly because face to face courses were cancelled. This study analyzes the results of participation and satisfaction of the AEC Virtual Classroom sessions during the first year. Methods: The AEC Virtual Classroom includes a combined format of weekly Webinar broadcast live that can be viewed on a delayed basis in a virtual platform. In this study, the results in its first year are evaluated considering the number of live participants, the delayed views and the global reach; as well as the results of the satisfaction survey in each of the sessions (0-10). Results: From 16/04/2020 to 15/04/2021, 50 sessions of the Virtual Classroom AEC were held. The average scope of the sessions was 509 ± 288 views with a range between 196 and 149. At the times of highest incidence of cases during the pandemic, a decrease in live participants was observed 275 ± 135 vs. 391 ± 233 (p = 0.032). The mean score on the format was 8.46 ± 0.31/10. The best-scored sessions were those of the subject related to coloproctology with a statistically significant difference in the mean score 8.79 ± 0.42 vs. 8.39 ± 0.27 (p = 0.035). 90% of users considered the sessions useful. 97.2% of respondents believe that the sessions should be maintained after the pandemic. Conclusions: The AEC Virtual Classroom has a very good results in the first year, proving to be a useful surgical teaching tool that will foreseeably survive once the pandemic is over.
RESUMO
BACKGROUND: There is still debate regarding the principal role and ideal timing of perioperative chemotherapy (CTx) for patients with upfront resectable colorectal liver metastases (CRLM). This study assesses long-term oncological outcomes in patients receiving neoadjuvant CTx only versus those receiving neoadjuvant combined with adjuvant therapy (perioperative CTx). METHODS: International multicentre retrospective analysis of patients with CRLM undergoing liver resection between 2010 and 2015. Characteristics and outcomes were compared before and after propensity score matching (PSM). Primary endpoints were long-term oncological outcomes, such as recurrence-free survival (RFS) and overall survival (OS). Furthermore, stratification by the tumour burden score (TBS) was applied. RESULTS: Of 967 patients undergoing hepatectomy, 252 were analysed, with a median follow-up of 45 months. The unmatched comparison revealed a bias towards patients with neoadjuvant CTx presenting with more high-risk patients (p = 0.045) and experiencing increased postoperative complications ≥Clavien-Dindo III (20.9% vs. 8%, p = 0.003). Multivariable analysis showed that perioperative CTx was associated with significantly improved RFS (hazard ratio [HR] 0.579, 95% confidence interval [CI] 0.420-0.800, p = 0.001) and OS (HR 0.579, 95% CI 0.403-0.834, p = 0.003). After PSM (n = 180 patients), the two groups were comparable regarding baseline characteristics. The perioperative CTx group presented with a significantly prolonged RFS (HR 0.53, 95% CI 0.37-0.76, p = 0.007) and OS (HR 0.58, 95% CI 0.38-0.87, p = 0.010) in both low and high TBS patients. CONCLUSIONS: When patients after resection of CRLM are able to tolerate additional postoperative CTx, a perioperative strategy demonstrates increased RFS and OS in comparison with neoadjuvant CTx only in both low and high-risk situations.

BACKGROUND: Pancreatic consistency is one of the most widely accepted risk factors of clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreatectoduodenectomy (PD). The present study aims to identify preoperative characteristics from the preoperative computed tomography (CT) associated with an increased risk. METHODS: Retrospective observational cohort study of patients who underwent PD surgery (January 2010-2019) were enrolled. All patients with available preoperative imaging were included; 103 met the inclusion criteria. Several parameters were measured on preoperative abdominal CT: retrorenal adipose tissue; abdominal perimeter; total adipose tissue, visceral and subcutaneous; skeletal muscle mass; main pancreatic duct (MPD) diameter; pancreatic thickness; remnant pancreatic volume; pancreatic attenuation (pancreas-to-spleen ratio). Primary endpoints were the association of radiological variables with soft pancreatic consistency and POPF development. All variables possibly associated with POPF and soft pancreas were subsequently included into a multivariable logistic regression model. RESULTS: Soft pancreas consistency was found in 43 patients (41.7%) and CR-POPF was higher (51.2% vs. 18%, p < 0.001). Multivariable analysis identified MPD ≤ 3 mm (OR = 7.2, 95%CI 2.3-23, p = 0.001), a remnant pancreatic volume ≥ 20 cm3 (OR = 6.4, 95%CI 2-21, p = 0.041), pancreas-to-spleen < 0.8 (OR = 3.2, 95%CI 1.2-8.4, p = 0.039), and retrorenal adipose tissue ≥ 12 cm3 (OR = 5.3, 95%CI 1.8-15.7, p = 0.013). Multivariable analysis showed MPD ≤ 3 mm (OR = 8.25, 95%CI 2.2-30.8, p = 0.002) and total adipose tissue ≥ 190 cm3 (OR = 3.2, 95%CI 1.1-9.1, p = 0.0027) were independent predictors of CR-POPF. CONCLUSION: The preoperative assessment of MPD, remnant pancreatic volume, pancreas-to-spleen ratio, total adipose tissue, and retrorenal adipose tissue are associated with soft pancreas texture and the risk of CR-POPF.

Introduction: The pandemic produced by SARS-CoV-2 has obliged us to set up the tele-assistance to offer a continuity of care. This implies an innovation, being the degree of satisfaction of patients unknown. Methods: A telephonic survey was conducted with the validated in the Spanish tool Telehealth Usability Questionnaire (Telehealth Usability Questionnaire; rating from 1-7) of all candidate patients assisted consecutively in the Coloproctology Unit. We included demographic variables, education level, job status, diagnosis and consultation type. A descriptive study was done. The relationship between the willingness of consultation model in the future (telemedicine vs traditional) and the categorical variables was analysed through the chi-squared test. Results: A total of 115 patients were included. The average age was 59.9 years, being 60% women. The average score in each of the survey items was higher than 6 in all the questions but 1. 26.1% of the surveyed patients confessed being advocated to tele-assistance in the future. The only factors related to greater willingness to tele-assistance were male gender (37% vs 18.8%; P = .03) and a higher academic preparation level in favour of higher technical studies (35.9%) and university studies (32.4%) opposite to the rest (P = .043). The rest of variables studied, job status, labour regimen, diagnostic group and consultation type did not show any relationship. Conclusions: A vast majority of patients answered favourably to almost all the items of the survey. However, only 26.1% of them would choose a model of tele-assistance without restrictions.

BACKGROUND: Distal pancreatectomy with celiac axis resection (DP-CAR) is a surgical procedure with high morbidity and mortality performed in patients with locally advanced pancreatic cancer. Preoperative embolization of hepatic artery (PHAE) has been postulated as a technical option to increase resection rate. OBJECTIVE: comparison of morbidity and mortality at 90 days, operative time, hospital stay and survival between patients that performed DP-CAR with and without PHAE. METHODS: Observational retrospective multicentre study. INCLUSION CRITERIA: patient operated in Spanish centers with DP-CAR for pancreatic cancer from April 2004 until 23 June 2018. Preoperative (PHAE, neodjuvant treatment), intraoperative (operative time and blood loss) and postoperative data (morbidity, hospital stay, R0 and survival) were studied. Complications were measured with Clavien classification at 90 days. Specific pancreatic complications were measured using ISGPS classifications. Data were analyzed using R version 3.1.3 (http://www.r-project.org). Level of significance was set at 0.05. RESULTS: 41 patients were studied. 26 patients were not embolized (NO-PHAE group) and 15 patients received PHAE. Preoperative BMI and percentage of neoadjuvant chemotherapy were the only preoperative variables different between both groups. The operative time in the PHAE group was shorter (343 min) than in the non-PHAE group (411 min) (p < 0.06). Major morbidity (Clavien > IIIa) and mortality at 90 days were higher in the PHAE group than in the non-PHAE group (60% vs 23% and 26.6% vs 11.6% respectively) (p < 0.004). No statistical difference in overall survival was observed between both groups (p = 0.14). CONCLUSION: In our study PHAE is not related with less postoperative morbidity. Even more, major morbidity (Clavien III-IV) and mortality was higher in PHAE group.

BACKGROUND: Adequate fluid resuscitation is paramount in the management of acute pancreatitis (AP). The aim of this study is to assess benefits and harms of fluid therapy protocols in patients with AP. METHODS: MEDLINE, Embase, Science Citation Index and clinical trial registries were searched for randomised clinical trials published before May 2020, assessing types of fluids, routes and rates of administration. RESULTS: A total 15 trials (1073 participants) were included. Age ranged from 38 to 73 years; follow-up period ranged from 0.5 to 6 months. Ringer lactate (RL) showed a reduced number of severe adverse events (SAE) when compared to normal saline (NS) (OR 0.48; 95%CI 0.29-0.81, p = 0.006); additionally, NS showed reduced SAE (RR 0.38; 95%IC 0.27-0.54, p < 0.001) and organ failure (RR 0.30; 95%CI 0.21-0.44, p < 0.001) in comparison with hydroxyethyl starch (HES). High fluid rate fluid infusion showed increased mortality (OR 2.88; 95%CI 1.41-5.88, p = 0.004), increased number of SAE (RR 1.42; 95%CI 1.04-1.93, p = 0.030) and higher incidence of sepsis (RR 2.80; 95%CI 1.51-5.19, p = 0.001) compared to moderate fluid rate infusion. CONCLUSIONS: In patients with AP, RL should be preferred over NS and HES should not be recommended. Based on low-certainty evidence, moderate-rate fluid infusion should be preferred over high-rate infusion.

BACKGROUND: There is still uncertainty regarding the role of perioperative chemotherapy (CTx) in patients with resectable colorectal liver metastases (CRLM), especially in those with a low-risk of recurrence. METHODS: Multicentre retrospective analysis of patients with CRLM undergoing liver resection between 2010-2015. Patients were divided into two groups according to whether they received perioperative CTx or not and were compared using propensity score matching (PSM) analysis. Then, they were stratified according to prognostic risk scores, including: Clinical Risk Score (CRS), Tumour Burden Score (TBS) and Genetic And Morphological Evaluation (GAME) score. RESULTS: The study included 967 patients with a median follow-up of 68 months. After PSM analysis, patients with perioperative CTx presented prolonged overall survival (OS) in comparison with the surgery alone group (82.8 vs 52.5 months, p = 0.017). On multivariable analysis perioperative CTx was an independent predictor of increased OS (HR 0.705, 95%CI 0.705-0.516, p = 0.029). The benefits of perioperative CTx on survival were confirmed in patients with CRS and TBS scores ≤2 (p = 0.022 and p = 0.020, respectively) and in patients with a GAME score ≤1 (p = 0.006). CONCLUSION: Perioperative CTx demonstrated an increase in OS in patients with CRLM. Patients with a low-risk of recurrence seem to benefit from systemic treatment.

BACKGROUND: Various parameters have been considered for predicting survival in pancreatic ductal adenocarcinoma. Information about western population is missing. The aim of this study is to assess the association between Glucose transporter type 1 (GLUT-1) expression and prognosis for patients with PDAC submitted for surgical resection in a European cohort. METHODS: Retrospective analysis of PDAC specimens after pancreatoduodenectomy assessing GLUT-1 expression according to intensity (weak vs strong) and extension (low if < 80% cells were stained, high if > 80%) was performed. Statistical analysis was performed using the exact Fisher test, Student t test or the Mann-Whitney U test. Survival was analysed using the Kaplan-Meier method and compared with the Log-rank test. The differences were considered significant at a two-sided p value of < 0.05. All statistical analyses were performed using SPSS® 23.0 for Windows (SPSS Inc., Chicago, IL, USA). RESULTS: Our study consisted of 39 patients of which 58.9% presented with weak and 41.1% with strong intensity. The median extension was 90%: 28.2% cases presented with a low extension and 71.8% with a high extension. No significant differences related to intensity were found. The high-extension group showed a higher percentage of T3 PDAC (92.9% vs 63.6%, p = 0.042) and LNR20 (35.7% vs 0%, p = 0.037) as well as shorter disease-free survival (17.58 vs 54.46 months; p = 0.048). CONCLUSIONS: Our findings suggest that GLUT-1 could be related to higher aggressivity in PDAC and could be used as a prognostic marker, identifying patients with a worse response to current therapies who could benefit from more aggressive treatments.

INTRODUCTION: The prognosis of pancreatic ductal adenocarcinoma has been associated with several factors. The aim of the present study was to correlate tumor-related factors and pathological findings with disease-free survival (DFS) and overall survival (OS) in patients undergoing pancreaticoduodenectomy. MATERIAL AND METHODS: From a prospectively maintained database, we reviewed 89 pancreatic ductal adenocarcinomas in patients who underwent pancreaticoduodenectomy from 2010 to 2014. The impact of histopathologic or tumor-related data, including a lymph node ratio greater than 15% (LNR15), on survival was analyzed. RESULTS: Univariate analysis of DFS and OS showed that vascular resection, pT, pN, LNR15, microvascular, lymphatic, and perineural invasion, and R1 resection influenced survival. Only LNR15, perineural invasion and R1 resection were independent predictors for both DFS (HR 6.39, p = 0.011; HR 8.53, p = 0.003; HR 9.68, p = 0.002, respectively) and OS (HR 4.21, p = 0.039; HR 5.41, p = 0.020; HR 4.41, p = 0.036, respectively). CONCLUSIONS: This study demonstrates that LNR15, perineural invasion and R1 resection are independently associated with DFS and OS.

OBJECTIVE: To compare the rates of R0 resection in pancreatoduodenectomy (PD) for pancreatic and periampullary malignant tumors by means of standard (ST-PD) versus artery-first approach (AFA-PD). BACKGROUND: Standardized histological examination of PD specimens has shown that most pancreatic resections thought to be R0 resections are R1. "Artery-first approach" is a surgical technique characterized by meticulous dissection of arterial planes and clearing of retropancreatic tissue in an attempt to achieve a higher rate of R0. To date, studies comparing AFA-PD versus ST-PD are retrospective cohort or case-control studies. METHODS: A multicenter, randomized, controlled trial was conducted in 10 University Hospitals (NCT02803814, ClinicalTrials.gov). Eligible patients were those who presented with pancreatic head adenocarcinoma and periampullary tumors (ampulloma, distal cholangiocarcinoma, duodenal adenocarcinoma). Assignment to each group (ST-PD or AFA-PD) was randomized by blocks and stratified by centers. The primary end-point was the rate of tumor-free resection margins (R0); secondary end-points were postoperative complications and mortality. RESULTS: One hundred seventy-nine patients were assessed for eligibility and 176 randomized. After exclusions, the final analysis included 75 ST-PD and 78 AFA-PD. R0 resection rates were 77.3% (95% CI: 68.4-87.4) with ST-PD and 67.9% (95% CI: 58.3-79.1) with AFA-PD, P=0.194. There were no significant differences in postoperative complication rates, overall 73.3% versus 67.9%, and perioperative mortality 4% versus 6.4%. CONCLUSIONS: Despite theoretical oncological advantages associated with AFA-PD and evidence coming from low-level studies, this multicenter, randomized, controlled trial has found no difference neither in R0 resection rates nor in postoperative complications in patients undergoing ST-PD versus AFA-PD for pancreatic head adenocarcinoma and other periampullary tumors.

Introduction: Management of asymptomatic Meckel's diverticulum (MD) incidentally discovered in adults remains controversial. The aim of this study was to determine if incidental diverticula should be removed. Materials and methods: We reviewed a consecutive series of patients surgically managed from January 1994 to December 2016. Patients were divided into two groups according to symptomatic or asymptomatic diverticula, and characteristics were compared. Results: The study included 66 patients: 30 in the symptomatic group (45%) and 36 in the incidental group (55%). We found 12 females (18.2%), and the ratio male:female was higher in the symptomatic group (14:1 vs. 2.6:1). Patients in the symptomatic group were significantly younger: 41.7 ± 18.1 vs. 54.7 ± 19.8 years (p = .007). MD in the symptomatic group tended to be longer (3.8 ± 1.9 vs. 2.6 ± 0.9 cm; p = .003). A MD-associated malignancy was present in three patients (4.5%), all neuroendocrine tumours. Major postoperative complications occurred in 6.6% of symptomatic patients and 0% within the incidental group, without specific morbidity related to prophylactic surgery. No mortality was observed. Conclusion: Resection of incidentally found Meckel's diverticulum can be made because of benefits outweigh the risks in this high-risk area for cancer.

BACKGROUND & AIMS: Chronic hepatitis C (CHC) is a major cause of cirrhosis and hepatocellular carcinoma and angiogenesis is closely related to the pathogenesis and progression of different chronic liver diseases (CLD). Thus, the intrahepatic expression of angiopoietins 1 and 2 (Ang1 and Ang2), as relevant mediators of pathological angiogenesis in several CLD, was investigated. In addition, the differential influence of structural and non-structural genomic regions of HCV on the expression of angiopoietins and the possible signalling involved were studied. METHODS: Ang1 and Ang2 expression was evaluated by western blotting and enzyme-linked immunosorbent assay (ELISA) in liver homogenates of CHC patients (n=47) and uninfected subjects (n=8). Their association with disease progression (according to METAVIR classification) was assessed by Spearman's correlation. Statistical differences among the expression of angiopoietins at different CHC stages were calculated by Mann-Whitney U-test. Finally, the in vitro expression of Angiopoietins in HCV replicons (complete or non-structural subgenomic) and the main signalling pathways involved were also examined. RESULTS: Ang2 levels were significantly higher in the liver of CHC patients compared to controls and significantly correlated with inflammation and fibrosis. Accordingly, an increased expression of Ang2 was found in all HCV replicons tested. Interestingly, the inhibition of MEK and PI3K signalling pathways exerted differential effects on Ang2 expression concerning to the genomic region of HCV. CONCLUSIONS: Hepatitis C virus induces Ang2 expression in hepatocytes through different signalling routes which may lead to the disregulation of vascular homeostasis in the liver. Thus, pharmacologic intervention on Ang2 signalling might constitute an important therapeutic tool.

Transhiatal herniation of the pancreas is an extremely rare condition, with only a few more than ten cases reported. Most patients are symptomatic at initial presentation and multi-detector computed tomography allows a detailed visualization of the anatomy and size of the diaphragmatic defect.

Severe acute pancreatitis occurs in around 20% of patients and is associated with mortality rates between 8-40%. Abdominal compartment syndrome is a fatal complication that is associated with new organ failure or acute worsening of existing organ failure and has an associated mortality of around 60%. Intra-abdominal pressure measurements are recommended in patients with risk factors for intra-abdominal hypertension or abdominal compartment syndrome. Management should be based on a step-up method and surgical intervention may be indicated when conservative treatment fails.
