    Abstract We report that decreased expression of miR-30c in tumor compared to adjacent tissue is sex-dependent in colorectal cancer (CRC) patients. High expression of miR-30c was associated with better survival in the whole cohort. When the cohort was split into male and female subcohorts, decreased miR-30c expression in tumor compared to adjacent tissue was observed only in males. Expression of miR-30c was decreased in CRC tumor tissue in male patients with nodes involvement compared to those without metastases in nodes and this difference was not observe in females. Next dependency of miR-30c expression on oestrogen receptor beta (ERbeta) mRNA levels in tumor was tested. In males with low expression of ERbeta, we observed a significant decrease in miR-30c levels in patients with nodes involvement compared to those without nodes involvement. This difference was not observed in males with high ERbeta mRNA levels and in females. Accordingly, males with low expression of ERbeta and high expression of miR-30c showed a better survival that those with low expression ERbeta and low expression of miR-30c. It is possible to conclude that whole cohort survival dependence on miR-30c is mostly generated by a subcohort of males with low expression of ERbeta mRNA in tumor tissue.

    Abstract Extensive drug treatment for coronavirus disease 2019 (COVID-19) includes low molecular weight heparin (LMWH). At therapeutic doses of LMWH, there is an increased risk of bleeding complications. Spontaneous, non-traumatic bleeding into the retroperitoneum is a life-threatening condition that can progress very rapidly. We describe a complication of COVID-19 bronchopneumonia treatment in which a patient developed a shock condition caused by non-traumatic bleeding into the retroperitoneum and abdominal wall due to LMWH overdose. The patient was operated on under difficult conditions - in biosafety level 3 (BSL-3). This case is exceptionally fascinating and informative. Nowadays, it is essential to point out possible complications associated with the treatment of COVID-19. Based on this report, we emphasize the need for careful LMWH dosing and quick and accurate diagnosis. Surgeons should maintain a higher index of suspicion for spontaneous bleeding in non-specific abdominal pain patients with COVID-19 or patients receiving therapeutic doses of LMWH.

    Abstract The incidence of colorectal cancer (CRC) shows a sex-dependent difference in humans. The aim of this study was to analyze estrogen receptor beta mRNA (ERbeta) expression in patients with CRC with respect to their gender and clinicopathological features. Since cancer progression is accompanied by tumor vascularization, VEGF-A (vascular endothelial growth factor A) transcription was analyzed along with ERbeta mRNA. ERbeta mRNA was also correlated with the expression of clock genes, which are known to influence the cell cycle. ERbeta mRNA expression in females with CRC showed an inverse association with increasing tumor staging that was not observed in males. Lower levels of ERbeta mRNA were observed in females with a higher clinical stage compared with those with earlier-stage tumors. ERbeta mRNA expression showed a significant positive correlation with mRNA of clock genes period 2 and cryptochrome 2 in healthy but not in cancerous tissue in males. Expression of VEGF-A mRNA showed a negative correlation with ERbeta mRNA after splitting of the cohort according to gender and nodus involvement. We propose that gender differences in ERbeta mRNA expression in tumors during the early stages of CRC can partially explain the lower occurrence of CRC in females compared with males.

    Abstract Aortodecubital fistula is a pathologic communication between aorta and a decubitus ulcer. It is very rarely encountered vascular condition in abdominal aortic aneurysms (AAA), with difficult diagnostics and high mortality. Patients often present with systemic and local infection and are at risk for hemorrhage. We present a paraplegic patient with fistulous communication between an inflamed abdominal aortic aneurysm and a sacral decubitus ulcer, leading to intermittent bleeding episodes and finally to exsanguination. While extremely rare, this case emphasizes the need for early, accurate diagnosis and salvage intervention when possible.

    Abstract Colorectal cancer (CRC) exhibits differences in its features depending on the location of the tumor. The role of the circadian system in carcinogenesis is accepted, and many studies report different clock gene expression in tumors compared to healthy tissue. However, little attention is given to the changes in clock genes in tumors arising from various locations across the colon and rectum. The aim of our study was to investigate the expression of the clock genes cry1 and cry2 in human CRC tissue and tissue adjacent to colorectal tumors in a cohort of 64 patients by real time PCR. Expression of cry1 in the entire patient cohort was higher in tumors compared to adjacent tissues in the right-sided colon but not in the left-sided colorectum. Difference in cry1 expression between tumor and adjacent tissue in the right-sided colon was preserved in women and a trend was observed in men. Higher expression of cry1 in the right-sided colon tumor tissue was associated with worse survival in women and the expression of cry1 in the left-sided colorectum was significantly higher in the adjacent tissue compared to tumor in men but not in women. Expression of cry2 was lower in the tumor than in adjacent tissue in both the right and left-sided colorectum. This trend was generally preserved, but the difference reached significance level only in the male left-sided colon, and cry2 expression in the tumor tissue significantly correlated with location of the tumor in men with grade 2 cancer. Finally, we detected significant correlation between tumor location and cry1 expression in the adjacent tissue and the combined results establish that tumor influence on adjacent tissue is dependent on tumor location. Changed clock gene expression should therefore be considered in specific CRC patient sub-groups.

    Abstract Mediastinal pancreatic pseudocysts are rarely encountered complications of pancreatic diseases. Pseudocysts most often expand into surrounding structures, just rarely into the mediastinum. Usually, they present with abdominal pain, and the symptoms correlate with the location of the pseudocysts. We describe a case of a pancreatic pseudocyst that penetrated the thoracic cavity through the diaphragm and set up a communication with the bronchial tree developing an episode of massive hemoptysis. This case is of particular interest because just a few similar cases were published before. Based on this report, we emphasize the need for early accurate diagnosis; surgeons should maintain a higher index of suspicion for mediastinal pancreatic pseudocyst in patients with chronic pancreatitis.

    Abstract miRNAs are small regulatory RNA molecules involved in posttranscriptional gene silencing. Their biosynthesis results in the formation of duplex consisting of a leading and a passenger strand of mature miRNA. The leading strand exhibits the main activity but recent findings indicate a certain role of the passenger strand as well. Deregulated levels of miRNA were found in many types of cancers including colorectal cancer. miR-21 and miR-16 were indicated as possible markers of colorectal cancer, however, small attention to gender differences in their expression was paid so far. Therefore, the aim of our study was to investigate the expression of miR-21-5p, miR-21-3p, miR-16-5p and miR-16-3p in human colorectal cancer tissue and compare it to the adjacent tissues taken during surgery in men and women separately. Our results showed an up-regulation of all measured miRNAs in tumor tissue compared to adjacent tissues. As expected, tumors and adjacent tissues exhibited a significantly higher expression of leading miRNAs compared to passenger strand of miR-21 and miR-16. The expression of leading and passenger strand of miR-21 and miR-16 positively correlated exhibiting the highest correlation coefficient in the distal tissue. The expression pattern showed gender-dependent differences, with higher levels of miRNA in men than in women. Our findings indicate a gender-related expression pattern of miRNA, which should be considered as an important factor in generating new prognostic or diagnostic biomarkers.

    Abstract Background: In primary hyperparathyreosis, US and scintigraphy are the most usual preoperative localization methods for detection of parathyroid adenomas or hyperplasia.
    Results: 88 (80 female) patients were detected. Unilateral neck exploration was performed in 43 patients (48.9 %) and bilateral exploration in 45 patients (51.1 %). The cure rate was 97.6 %. None case of parathyroid hyperplasia was detected, there were 2 cases of duplex adenoma. For left/right and quadrant localization, sensitivity of US was 71.05 % and 55.07 %, of scintigraphy 95.77 % and 88.71 %, and in concordant imaging 97.67 % and 96.77 %. Analogically, PPV was: US 91.53 % and 76.00 %, scintigraphy 87.18 % and 74.32 %, concordant imaging 93.33 %and 81.08 %. Only US sensitivity was significantly lower, all other differences showed no statistical significance.
    Conclusion: Our data showed low sensitivity but a high positive predictive value of ultrasonography and a high diagnostic value of scintigraphy. Sensitivity and the positive predictive value of concordant localization showed no significant difference, compared to scintigraphy. The routine need for concordance for parathyroid adenoma localization appears dubious, however, its value for prediction of multiglandular disease remains important for protocols that do not apply peroperative localization (Tab. 2, Ref. 35).

    Abstract Introduction: The Enhanced Recovery After Cardiac Surgery protocol is the most recent addition to cardiac treatment. In this paper, we aimed to test the safety and viability of this protocol in our hospital to improve our standard of care.
    Methods: This study was conducted as an experimental study with a historical control at the Maritime Heart Center, Halifax, Nova Scotia, Canada. In order to quantify the success of this protocol, we measured the postoperative Length of Hospital Stay and three intensive care unit variables: time to extubation, time to ambulation, and opioid consumption. In the study, 100 patients were in the Enhanced Recovery After Cardiac Surgery group, and 103 patients were used as historic controls-selected by strenuous chart review and selection criteria.
    Results: The primary outcome (Length of Hospital Stay) was reduced from a mean of 8.88 ± 3.50 days in the control group to a mean of 5.13 ± 1.34 days in the Enhanced Recovery After Cardiac Surgery group (
    Conclusion: Enhanced Recovery After Cardiac Surgery protocols were seamlessly integrated into selected cardiac surgical patients, contingent on a high level of interprofessional communication and collaboration.
