RESUMO
The study of the microbiota and the microbiome, and specifically the intestinal one, has determined great interest due to the possible association of their alterations with numerous diseases. These include entities as diverse as Crohn's disease, autism, diabetes, cancer or situations as prevalent today as obesity. In view of this situation, different recommendations have been performed regarding the use of probiotics, prebiotics, and postbiotics as modulators of the microbiota and the microbiome, seeking both preventive and therapeutic effects, and faecal material transfer (FMT) is proposed as an alternative. The latter has emerged as the only proven beneficial intervention on the intestinal microbiome, specifically in the treatment of recurrent colitis associated with Clostridioides difficile (R-CDI). In the rest of the entities, the lowering of laboratory costs has favored the study of the microbiome, which is resolved by delivering reports with catalogs of microorganisms, metabolites or supposed biomarkers without consensus on their composition associated with healthy or diseased microbiota and the disease. There is still insufficient evidence in any disease for interventions on the microbiome beyond FMT and R-CDI. Multi- and multi-disciplinary work with extensive research and the application of artificial intelligence in this field may shed light on the questions raised currently. Ethical issues must also be resolved in light of possible interventions within the umbrella of personalized medicine.
RESUMO
This document is the result of the deliberations of the Committee on Emerging Pathogens and COVID-19 of the Illustrious Official College of Physicians of Madrid (ICOMEM) regarding the current situation of tuberculosis, particularly in Spain. We have reviewed aspects such as the evolution of its incidence, the populations currently most exposed and the health care circuits for the care of these patients in Spain. We have also discussed latent tuberculosis, the reality of extrapulmonary disease in the XXI century and the means available in daily practice for the diagnosis of both latent and active forms. The contribution of molecular biology, which has changed the perspective of this disease, was another topic of discussion. The paper tries to put into perspective both the classical drugs and their resistance figures and the availability and indications of the new ones. In addition, the reality of direct observation in the administration of antituberculosis drugs has been discussed. All this revolution is making it possible to shorten the treatment time for tuberculosis, a subject that has also been reviewed. If everything is done well, the risk of relapse of tuberculosis is small but it exists. On the other hand, many special situations have been discussed in this paper, such as tuberculosis in pediatric age and tuberculosis as a cause for concern in surgery and intensive care. The status of the BCG vaccine and its present indications as well as the future of new vaccines to achieve the old dream of eradicating this disease have been discussed. Finally, the ethical and medicolegal implications of this disease are not a minor issue and our situation in this regard has been reviewed.

Sexually Transmitted Infections (STI) are a major public health problem. The problems inherent to their diagnosis, treatment and prevention have to do not only with their nature, but also with organizational issues and overlapping competencies of the different health authorities in Spain. The real situation of STI in Spain, at present, is poorly known. For this reason, the Scientific Committee on COVID and Emerging Pathogens of the Illustrious Official College of Physicians of Madrid (ICOMEM) has formulated a series of questions on this subject which were distributed, not only among the members of the Committee, but also among experts outside it. The central health authorities provide very high and increasing figures for gonococcal infection, syphilis, Chlamydia trachomatis infection and lymphogranuloma venereum (LGV). Both HIV infection and Monkeypox are two important STI caused by viruses in our environment, to which it should be added, mainly, Herpes simplex virus (HSV) and Human papillomavirus (HPV) infections. Emerging microorganisms such as Mycoplasma genitalium pose not only pathogenic challenges but also therapeutic problems, as in the case of N. gonohrroeae. The pathways that patients with suspected STI follow until they are adequately diagnosed and treated are not well known in Spain. Experts understand that this problem is fundamentally managed in public health institutions, and that Primary Care and Hospital Emergency Services, together with some institutions that deal monographically with this problem, are the recipients of most of these patients. One of the most serious difficulties of STI lies in the availability of the microbiological tests necessary for their diagnosis, particularly in this era of outsourcing of microbiology services. Added to this is the increased cost of implementing the latest generation of molecular techniques and the difficulties of transporting samples. It is clear that STI are not diseases to which the entire population is equally exposed and it is necessary to have a better knowledge of the risk groups where to focus the necessary interventions adapted to their characteristics. It should not be forgotten that STI are also a problem in the pediatric age group and that their presence can be a marker of sexual abuse with all that this implies in terms of health care and medicolegal activity. Finally, STI are infections that are associated with a high cost of care for which we have very little information. The possibility of expanding the automatic performance of laboratory tests for STI surveillance through laboratory routines is encountering ethical and legal problems that are not always easy to solve. Spain has created a ministerial area of specific attention to STI and there are plans to improve the diagnosis, treatment and prevention of these problems, but we still lack the necessary evidence on their impact. We cannot forget that these are diseases that transcend the individual and constitute a Public Health problem.

The SARS-CoV-2 (COVID-19) pandemic requires an analysis in the field of oncological surgery, both on the risk of infection, with very relevant clinical consequences, and on the need to generate plans to minimize the impact on possible restrictions on health resources. The AEC is making a proposal for the management of patients with hepatopancreatobiliary (HPB) malignancies in the different pandemic scenarios in order to offer the maximum benefit to patients, minimising the risks of COVID-19 infection, and optimising the healthcare resources available at any time. This requires the coordination of the different treatment options between the departments involved in the management of these patients: medical oncology, radiotherapy oncology, surgery, anaesthesia, radiology, endoscopy department and intensive care. The goal is offer effective treatments, adapted to the available resources, without compromising patients and healthcare professionals safety.

BACKGROUND: Chemotherapy-associated liver injury (CALI) is a matter of concern for hepatobiliary surgeons as it can entail postoperative liver failure after an extensive hepatectomy. Recent studies have taken special interest in liver function parameters which can correlate with CALI to decrease this adverse event. Therefore, the current study investigates the usefulness of splenic volume as a biomarker of CALI through a portal hypertension mechanism, in patients with colorectal liver metastases (CRLM). STUDY DESIGN: We carried out a study in patients with CRLM operated on between 2009 and 2014 in our center. All samples of healthy liver were graded for non-alcoholic fatty liver disease (NAFLD) and sinusoidal obstructive syndrome. Computarized tomography scans for spleen volumetry were analyzed for each patient at CRLM diagnosis, after neoadjuvant chemotherapy, 1 and 6 months after resection. RESULTS: A group of 65 consecutive patients with CRLM of large bowel adenocarcinoma submitted to liver resection were included. Patients receiving neoadjuvant chemotherapy had a greater spleen volume increase than those who did not receive treatment (p = 0.053), finding a statistically significant spleen growth in patients with NAFLD (p = 0.036). There was no correlation between spleen enlargement and postoperative complications or average stay. However, survival was decreased in patients with spleen growth and CALI. CONCLUSIONS: Patients who receive neoadjuvant chemotherapy for liver metastasis surgery have a greater splenic volume increase, which correlates with NAFLD and a lower survival.

The hepatocellular carcinoma (HCC) is the fifth most frequent tumor in the world, and the third cause of death related to cancer. Histological samples obtained from diseased liver likely to have HCC are currently prescribed in selected patients in whose imaging studies and tumor markers are not sufficient for the diagnosis. In recent years, a risk of tumoral seeding along needle tract of FNAC to obtain histological samples has been reported. We present a case of tumor implantation of HCC cells in the needle tract, a year and four months after a percutaneous fine needle aspiration cytology (FNAC).

AIM: The aim of the present study is to evaluate the prognostic influence of loss of heterozygosity on 2p, 3p, 5q, 17p and 18q, and c-myc overexpression on surgically treated sporadic colorectal carcinoma. METHODS: Tumor and non-tumor tissue samples from 153 patients were analyzed. Fifty-one percent of patients were male, and mean age in the series was 67 years. Tumors were located in the proximal colon in 37 cases, in the distal bowel in 37, and in the rectum in 79 patients. c-myc overexpression was studied by means of Northern blot analysis, and loss of heterozygosity through microsatellite analysis. RESULTS: c-myc overexpression was detected in 25% of cases, and loss of heterozygosity in at least one of the studied regions in 48%. There was no association between clinical and pathologic features, and genetic alterations. The disease-free interval was significantly shorter for patients with both genetic alterations; the presence of both events was an independent prognostic factor for poor outcome in the multivariate analysis (RR: 4.34, p < 0.0001). CONCLUSIONS: The presence of both loss of heterozygosity and overexpression of the c-myc oncogene separates a subset of colorectal carcinoma patients who have a shorter disease-free interval after curative-intent surgery.
