Introduction Adenomatous polyps are pivotal to the development of colorectal cancer. The risk of colorectal carcinogenesis can be reduced through polypectomy and close surveillance of the disease. Early-stage polyps can be detected and removed endoscopically, therefore, reducing the incidence of carcinoma. The identification of CSC in colon polyps allows for assessment of their potential malignancy. Therefore, it is very relevant to study the prognostic significance of the prevalence of stem cells in colorectal polyps in early detection and prevention of cancer. Method Previously pathologically evaluated adenomatous tumors (60M, 40F) at Azerbaijan Medical University were reevaluated in Meram Medical Faculty Pathology Department. Hematoxylin-Eosin-stained slides were examined and cases with and without dysplasia were determined. New sections were taken from paraffin blocs. Prominin-1 staining was performed immunohistochemically on these sections. read more Stained slides were examined by an image analysis system. Prominin-1-positive cells were automatically counted with the same image analysis system. The cases that developed malignancy after polypectomy were determined. The relationship between CD133 expression of dysplasia and malignancy was statistically analyzed. Results Statistically significant prominin-1 expression was detected in cases with dysplasia and malignancy. Conclusion The investigation of prominin-1 expression in colorectal polyps may be important to determine malignancy development.Introduction Injuries of the carotid artery constitute a rare group of injuries. This study presents results of the treatment of 44 patients with iatrogenic carotid artery injuries for over 20 years. The patients were treated by the team of doctors of the Department of Vascular, General and Transplant Surgery in Wroclaw in the years 1997-2017 (Head of the Department Prof. Klemens Skóra, MD, and Prof. Piotr Szyber, MD, PhD - material used with permission). Aim Aims of the analysis are to estimate the frequency of different forms of iatrogenic injuries to the common and internal carotid artery, to evaluate the results of treatment, to assess the most effective surgical method depending on the type of injury, and develop an effective preoperative, intraoperative and postoperative regimen. Discussion and results The frequency of various carotid artery injuries (blunt, acute, traffic) was constant between years, but the number of iatrogenic injuries definitely increased over time. The prognosis for patients with carotid artery injury, especially when combined with multi-organ trauma, is the gravest. Significantly better treatment results were achieved with both acute and iatrogenic injuries. This is mainly due to easier and quicker diagnosis and better conditions for assisting patients. Conclusions In iatrogenic injuries, a well-designed surgical scheme, i.e. primarily the administration of UTH and placing a temporary flow drain by the first operating team, reduces the risk of neurological complications. Introduction Pediatric inflammatory multisystem syndrome - temporally associated with SARS-CoV-2 (PIMS-TS) is a new disease, the first cases of which were observed in the spring of 2020. It affects children who have been infected with SARS-CoV-2 virus (severe acute respiratory syndrome coronavirus 2) and children who have been in direct contact with patients suffering from COVID-19 (coronavirus disease 2019). The disease is characterized by a wide spectrum of symptoms and the development of generalized inflammation of different organs and systems. One of the numerous symptoms may be severe abdominal pain. Aim The aim of this study was to review the available literature and analyze the results of patients treated at the Department of Pediatric Surgery, Traumatology and Urology in Poznań in whom PIMS-TS imitated acute surgical abdominal disease. Materials and methods material for the study was collected on the basis of medical records of patients treated at the Department of Pediatric Surgery, Traumatology and Urology of the Poznań University of Medical Sciences in the period between March 2020 and February 2021. Results TDuring this period, seven patients met the PIMS-TS criteria and three children were qualified for surgical treatment. Only one patient had an acute surgical cause of abdominal pain. Discussions The guidelines of the expert group at the Polish Pediatric Society and the National Consultant in the field of Pediatrics indicate the need to exclude acute surgical abdominal disease as a criterion for the diagnosis of PIMS-TS syndrome. In patients with acute abdominal pain, imaging and laboratory tests are sometimes diagnostically inconclusive, therefore exploratory laparoscopy is worth considering in order to differentiate PIMS-TS from acute surgical abdominal disease.Introduction There are many natural approaches that may improve the nutritional status in malnourished patients. Increased consumption of natural food is a more physiological, attractive, and available form of nutritional therapy of patients than medical nutrition. However, in specific clinical situations, oral nutritional supplements (ONS) may constitute a good support of nutritional management in malnourished cancer patients. Selecting proper ONS and their appropriate use may reduce the risk and progression of malnutrition and significantly affect oncological patient's treatment as well as decrease the rate of postoperative complications. Oral nutritional supplements should be the first nutritional choice to prevent and correct nutritional disorders in oncological surgery patients, especially during the pandemic, with the connected inability to visit patients. Despite this, many specialists recommend improperly adjusted preparations, and they do not consider all ailments and diseases of the patient. If ONS are overused or used inappropriately, they can cause many clinical disorders. Aim This paper aimed to help explain and understand the general recommendations on the proper administration of ONS, their benefits, and difficulties connected with their use in clinical practice. Introduction The COVID-19 pandemic is an exceptional situation which has rigorously affected surgical education and training worldwide. This current situation has carved innovative ways like online teaching to counter the challenges of the pandemic faced by a surgical resident. However, online teaching is not complimentary to bedside teaching which is a traditional practice. Therefore, we designed this study to assess the residents' perceptive towards online learning as a mode of education which is extensively implemented during the COVID-19 pandemic at our centre. Methods This study was a cross-sectional survey. An online Google survey was circulated among junior residents in the department of General Surgery. This survey included residents' demographic profile, effect on working hours, their perception with online teaching, and effect on their surgical training during the COVID 19 pandemic. Results A total of 95 junior residents participated in this study. Surgical training and teaching was rigorously affected according to most of them and they also believe they have lost crucial training time in their tenure as a surgical resident. A majority found the communication with the faculty during online teaching adequate; however, the main drawback of online classes was the lack of clinical exposure and practical experience. Only 4.2% preferred 100% online teaching in future. Conclusion COVID-19 pandemic has affected surgical training much more as compared to other medical fields. However, we believe online education is still a potential instrument during the COVID-19 pandemic. Online learning platforms can be used in future as a supplement to time-honoured classroom teaching and didactic lectures.Introduction Colorectal cancer (CRC), despite intensive research on the improvement of diagnosis and treatment, is still the second most deadly cancer in Poland in terms of mortality. One of the factors predisposing to a higher risk of CRC may be the individual differences in the effectiveness of proteins responsible for the metabolism of xenobiotics - it seems that the removal of potentially harmful exogenous substances significantly reduces the risk of carcinogenesis. Aim In this work, we analyzed the effect of polymorphisms of genes responsible for metabolizing xenobiotics on the risk of CRC - rs72554606 polymorphism of N AT 1 gene, rs1799930 polymorphism of N AT 2 gene and rs1799814 polymorphism of CYP1A1 gene, as well as the level of expression of these genes. Conclusions The results indicate that the GC genotype for N AT 1 and the GA genotype for CYP1A1 may increase the risk of CRC, and in those already diagnosed with colorectal cancer, the expression level of NAT1 is significantly lower than in the control. We believe that these factors may have potential prognostic and diagnostic significance in the treatment of CRC.Within the cytoplasm of mammalian cells is a protein called cyclic GMP-AMP synthase (cGAS), which acts to defend against infection and other threats to the host. cGAS operates in this manner through its ability to detect a molecular occurrence that should not exist in healthy cells - the existence of DNA in the cytosol. Upon DNA binding, cGAS synthesizes cyclic GMP-AMP (cGAMP), a cyclic dinucleotide that activates the endoplasmic reticulum-localized protein stimulator of interferon genes (STING). STING-mediated signaling culminates in host defensive responses typified by inflammatory cytokine and interferon expression, and the induction of autophagy. Studies over the past several years have established a consensus in the field of the enzymatic activities of cGAS in vitro, as it relates to DNA-induced production of cGAMP. However, much additional work is needed to understand the regulation of cGAS functions within cells, where multiple sources of DNA can create a problem of self and non-self discrimination. In this review, we provide an overview of how the cGAS-STING pathway mediates innate immune responses during infection and other cellular stresses. We then highlight recent progress in the understanding of the increasingly diverse ways in which this DNA-sensing machinery is regulated inside cells, including how cGAS remains inactive to host-derived DNA under conditions of homeostasis.

To investigate independent factors for the efficacy and safety of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of diffuse malignant peritoneal mesothelioma (DMPM).

The clinical database of 110 DMPM patients treated with CRS + HIPEC at our hospital was retrospectively analyzed. Independent prognostic factors were screened using univariate and multivariate analyses and the safety of the perioperative period was evaluated based on adverse events.

Among the 110 patients with DMPM, 34 (30.9%) had a peritoneal cancer index (PCI) < 20 and 76 (69.1%) had PCI ≥20; 59 (53.6%) patients achieved completeness of cytoreduction (CC) 0/1 and 51 (46.4%) cases achieved CC 2/3. At the median follow-up of 43.3 (95%CI 37.3-49.4) months, 48 (43.6%) patients were still alive and 62 (56.4%) patients died. The median overall survival was 32.6 months. Serious adverse events (SAEs) occurred in 41 patients (37.3%) and the perioperative mortality rate was 2.7%. Univariate analysis identified nine prognostic factors Karnofsky performance status score, perioperative tumor markers, PCI, red blood cell infusion, pathological type, vascular tumor emboli, lymphatic metastasis, Ki-67 index, and perioperative SAEs (all
