The aim of the study was to identify how diversity is conveyed by the University to the Society. A content analysis of diversity-related news items in the University’s Institutional Newspaper Journal of the Pablo de Olavide University (DUPO) (626 news items out of 3,186 published between 2016 and 2019, a full rector’s term) was conducted. Heterogeneity in diversity was identified: gender, functional, cultural, sexual, religious and age, with gender and functional or disability diversity being predominant. Dissemination of diversity was linked to the fields of social sciences, humanities and sport. Communicators were government teams, with a slightly larger role for women. In conclusion, the institutional communication of diversity carried out from the most common official communication channel of the university analysed is the majority compared to the actions of professors and researchers, and a heterogeneous conception of diversity was found, linking it to issues of gender, inequalities and violence.Universidad Pablo de Olavide de Sevilla.

Autologous and Allogeneic Stem Cell Transplantation for Treatment of Crohn’s Fistulae
Up to 20% of patients with Crohn’s disease (CD) may have perianal fistula disease. Classically, surgery has played an important role; in recent years, medical treatment has taken a leading role. Immunosuppressants and biological trea tments have proven beneficial in many patients, but still, the percentage of patients who do not respond remains significant. In this scenario, cell therapy is envisaged as an effective alternative to surgery. The promising preclinical and clinical data that we review below suggest that cell therapy could represent a major advance in the clinical management of this difficult problem
Staphylococcus epidermidis strains isolated from breast milk of women suffering infectious mastitis: potential virulence traits and resistance to antibiotics
<p>Abstract</p> <p>Background</p> <p>Although <it>Staphylococcus aureus </it>is considered the main etiological agent of infectious mastitis, recent studies have suggested that coagulase-negative staphylococci (CNS) may also play an important role in such infections. The aims of this work were to isolate staphylococci from milk of women with lactational mastitis, to select and characterize the CNS isolates, and to compare such properties with those displayed by CNS strains isolated from milk of healthy women.</p> <p>Results</p> <p>The milk of 30 women was collected and bacterial growth was noted in 27 of them, of which <it>Staphylococcus epidermidis </it>was isolated from 26 patients and <it>S. aureus </it>from 8. Among the 270 staphylococcal isolates recovered from milk of women with mastitis, 200 were identified as <it>Staphylococcus epidermidis </it>by phenotypic assays, species-specific PCR and PCR sequencing. They were typified by pulsed field gel electrophoresis (PFGE) genotyping. The PFGE profiles of the <it>S. epidermidis </it>strains were compared with those of 105 isolates from milk of healthy women. A representative of the 76 different PFGE profiles was selected to study the incidence of virulence factors and antibiotic resistance. The number of strains that contained the biofilm-related <it>ica</it>D gene and that showed resistance to oxacillin, erythromycin, clindamycin and mupirocin was significantly higher among the strains isolated from mastitic milk.</p> <p>Conclusion</p> <p><it>S. epidermidis </it>may be a frequent but largely underrated cause of infectious mastitis in lactating women. The resistance to diverse antibiotics and a higher ability to form biofilms found among the strains isolated from milk of women suffering mastitis may explain the chronic and/or recurrent nature of this infectious condition.</p
Comparing outcomes of robotic versus open mesorectal excision for rectal cancer
Background: The outcomes of robot-assisted mesorectal excision for rectal cancer, compared with open resection, have not been
fully characterized.
Methods: A retrospective analysis of pathologic, short-term, and long-term outcomes in patients with rectal adenocarcinoma who
underwent total or tumour-specific mesorectal excision at a high-volume cancer centre between 2008 and 2017 was conducted.
Outcomes after robotic and open surgery were compared on an intention-to-treat basis.
Results: Out of 1048 resections performed, 1018 patients were reviewed, with 638 who underwent robotic surgery and 380 open
surgery. Robotic surgery was converted to the open approach in 17 (2.7 per cent) patients. Patients who underwent robotic
surgery were younger (median 54 (range 22–91) years versus median 58 (range 18–97) years; P < 0.001), had higher tumours
(median 80 (range 0–150) mm from the anal verge versus median 70 (0–150) mm; P ¼ 0.001), and were less likely to have received
neoadjuvant therapy (64 per cent versus 73 per cent; P ¼ 0.003). For patients who underwent a robotic total mesorectal excision,
the operating time was longer (median 283.5 (range 117–712) min versus median 249 (range 70–661) min; P < 0.001). However, the
rate of complications was lower (29 per cent versus 45 per cent; P < 0.001) and length of hospital stay was shorter (median 5 (range
1–32) days versus median 7 (range 0–137) days; P < 0.001). Median follow-up of survivors was 2.9 years. The proportion of patients
with a positive circumferential resection margin did not differ between the groups, nor did the rate of local recurrence (robotic
versus open: 3.7 per cent, 95 per cent c.i. 1.9 to 5.6 versus 2.8 per cent, 95 per cent c.i. 1.0 to 4.6; P ¼ 0.400), systemic recurrence (ro-
botic versus open: 11.7 per cent, 95 per cent c.i. 8.5 to 14.8 versus 13.0 per cent, 95 per cent c.i. 9.2 to 16.5; P ¼ 0.300), or overall sur-
vival (robotic versus open: 97.8 per cent, 95 per cent c.i. 96.3 to 99.3 versus 93.5 per cent, 95 per cent c.i. 90.8 to 96.2; P ¼ 0.050). The
same results were documented in a subanalysis of 370 matched patients, including 185 who underwent robotic surgery and 185
open surgery, for the overall incidence of any postoperative complications, overall survival, disease-free survival, local recur-
rence, and systemic recurrence.
Conclusion: In patients with rectal cancer who are candidates for curative resection, robotic mesorectal excision is associated with
lower complication rates, shorter length of stay, and equivalent oncologic outcomes, compared with open mesorectal excisio
European guidelines from the EHTG and ESCP for Lynch syndrome: an updated third edition of the Mallorca guidelines based on gene and gender
Background: Lynch syndrome is the most common genetic predisposition for hereditary cancer but remains underdiagnosed.
Large prospective observational studies have recently increased understanding of the effectiveness of colonoscopic
surveillance and the heterogeneity of cancer risk between genotypes. The need for gene- and gender-specific guidelines has been
acknowledged.
Methods: The European Hereditary Tumour Group (EHTG) and European Society of Coloproctology (ESCP) developed a multidiscipli nary working group consisting of surgeons, clinical and molecular geneticists, pathologists, epidemiologists, gastroenterologists, and
patient representation to conduct a graded evidence review. The previous Mallorca guideline format was used to revise the clinical
guidance. Consensus for the guidance statements was acquired by three Delphi voting rounds.
Results: Recommendations for clinical and molecular identification of Lynch syndrome, surgical and endoscopic management of
Lynch syndrome-associated colorectal cancer, and preventive measures for cancer were produced. The emphasis was on surgical
and gastroenterological aspects of the cancer spectrum. Manchester consensus guidelines for gynaecological management were en dorsed. Executive and layperson summaries were provided.
Conclusion: The recommendations from the EHTG and ESCP for identification of patients with Lynch syndrome, colorectal surveil lance, surgical management of colorectal cancer, lifestyle and chemoprevention in Lynch syndrome that reached a consensus (at
least 80 per cent) are presented
Evaluation of the potential of total proanthocyanidin content in feces as an intake biomarker.
Due to the health benefits associated with proanthocyanidins (PAs), it is useful to identify dietary PA biomarkers that can be determined by simple methods. Since increased levels of circulating PA metabolites are associated with increased fecal PA content, this study explores the spectrophotometric measurement of fecal PA content and its use as a biomarker of PA intake. To this end, fecal PA content was measured using an adaptation of Porter’s spectrophotometric method in samples from a preclinical study and an observational study. In the former, excretion of 250–400 mg PA polymer equivalents/100 g feces was observed during supplementation and the day after, together with a significant association (p < 0.05) between PA intake and the excretion of both intact PAs and some PA metabolites, i.e., (+)-catechin, (−)-epicatechin and syringic acid. No relationship between intake and excretion was found in the observational study, either for the entire group (mean excretion of 240 ± 226 mg PA polymer equivalents/100 g feces) or after stratification into tertiles of consumption. In conclusion, the spectrophotometric determination of total PA content in feces proved to be a valid compliance marker in a preclinical study, but it was not associated with PA intake in free-living subjects. The potential of total PA excretion in observational studies, determined in fecal samples collected the day before dietary recall or in several fecal samples from the same subject, remains to be elucidated, as does a complete validation of the method proposed here.post-print552 K
Enhancing the hydrogen transfer catalytic activity of hybrid carbon nanotube-based NHC–iridium catalysts by increasing the oxidation degree of the nanosupport
CVD-grown multiwalled carbon nanotubes were purified by applying four different treatments with increasing oxidation severity. The growing severity of the treatment results in progressive oxygen functionalization of the surface along with introduction of an increasing quantity of defects on the carbon nanotube walls. Iridium-N-heterocyclic carbene complexes were covalently anchored to those oxidized surfaces through their surface carboxylic acids via acetyl linkers. The carbon nanotube-based iridium-NHC hybrid materials developed are active in the hydrogen-transfer reduction of cyclohexanone to cyclohexanol with 2-propanol/KOH as hydrogen source but with rather different activity. The catalytic activity of the hybrid catalysts is strongly influenced by the type and amount of oxygenated functionalization resulting from the treatment applied to the support, being the most active and the most oxidized material.The authors thank the Spanish Ministry of Economy and Competitiveness (MINECO/FEDER) (Projects Consolider Ingenio 2010 CSD2009-00050 and CTQ2013-42532-P) and the Diputación General de Aragón (FSE-E07 and FSE-E69) for their financial support.
