INTRODUCTION: According to the guidelines for preoperative assessment of lung resection candidates, patients with normal forced expiratory volume in 1 s (FEV1) and diffusing capacity of the lung for carbon monoxide (DLCO) are at low risk for post-operative pulmonary complications (PPC). However, PPC affect hospital length of stay and related healthcare costs. We aimed to assess risk of PPC for lung resection candidates with normal FEV1 and DLCO (>80% predicted) and identify factors associated with PPC. METHODS: 398 patients were prospectively studied at two centres between 2017 and 2021. PPC were recorded from the first 30 post-operative days. Subgroups of patients with and without PPC were compared and factors with significant difference were analysed by uni- and multivariate logistic regression. RESULTS: 188 subjects had normal FEV1 and DLCO. Of these, 17 patients (9%) developed PPC. Patients with PPC had significantly lower pressure of end-tidal carbon dioxide (PETCO2 ) at rest (27.7 versus 29.9; p=0.033) and higher ventilatory efficiency (V'E/V'CO2 ) slope (31.1 versus 28; p=0.016) compared to those without PPC. Multivariate models showed association between resting PETCO2 (OR 0.872; p=0.035) and V'E/V'CO2 slope (OR 1.116; p=0.03) and PPC. In both models, thoracotomy was strongly associated with PPC (OR 6.419; p=0.005 and OR 5.884; p=0.007, respectively). Peak oxygen consumption failed to predict PPC (p=0.917). CONCLUSIONS: Resting PETCO2 adds incremental information for risk prediction of PPC in patients with normal FEV1 and DLCO. We propose resting PETCO2 be an additional parameter to FEV1 and DLCO for preoperative risk stratification.

TACSTD2 encodes a transmembrane glycoprotein Trop2 commonly overexpressed in carcinomas. While the Trop2 protein was discovered already in 1981 and first antibody-drug conjugate targeting Trop2 were recently approved for cancer therapy, the physiological role of Trop2 is still not fully understood. In this article, we show that TACSTD2/Trop2 expression is evolutionarily conserved in lungs of various vertebrates. By analysis of publicly available transcriptomic data we demonstrate that TACSTD2 level consistently increases in lungs infected with miscellaneous, but mainly viral pathogens. Single cell and subpopulation based transcriptomic data revealed that the major source of TACSTD2 transcript are lung epithelial cells and their progenitors and that TACSTD2 is induced directly in lung epithelial cells following infection. Increase in TACSTD2 expression may represent a mechanism to maintain/restore epithelial barrier function and contribute to regeneration process in infected/damaged lungs.

Autoimmune pancreatitis is a rare form of chronic pancreatitis. The first descriptions of the disease date back to the 1990s. Etiology is multifactorial, with the use of genetic, environmental and complex immunological mechanisms. It is classified into two subtypes. Type 1 is part of a group of diseases called IgG4-related disease. Clinically is autoimmune pancreatitis manifested by icterus and abdominal discomfort. It can rarely present as acute pancreatitis. There is also a completely asymptomatic form of the disease. The diagnosis is based on abnormalities in histology, imaging methods, serology, the involvement of other organs in relation to IgG4-related disease, and a significant positive response to corticosteroid therapy. Differential diagnosis between the focal form of autoimmune pancreatitis and pancreatic cancer can be complicated, with endosonography playing an important role. In the treatment, we use corticosteroids and other immunosuppressants including biological therapy. Patients with the asymptomatic disease should also be treated to prevent late complications and exocrine and endocrine insufficiency. In addition to drug treatment, endoscopic and/or surgical treatment may be necessary. Even after recovery, the disease can relapse. The relationship between autoimmune pancreatitis and malignancies has not been clearly confirmed. The goal of this review is to provide a comprehensive look at autoimmune pancreatitis and translate latest scientific knowledge into clinical practice.

BACKGROUND: Antimicrobial coatings of central venous catheters (CVC) have the potential to reduce the risk of infectious complications. The aim of this study was to examine the efficacy of a catheter with a non-leaching antimicrobial coating against catheter colonization and bloodstream infections (BSI). METHODS: The study was conducted in two centers using a prospective, randomized, double-blind and controlled design (680 intensive care patients; a protective CVC (Certofix® protect) or a standard CVC (Certofix®). Primary objectives were the rates of catheter colonization and BSI in the two groups. Other baseline demographics, APACHE II score, insertion site, location of CVC placement (ICU or theatre), indwelling time and length of ICU stay were comparable for both groups. RESULTS: While the rate of catheter colonization between the coated and uncoated CVC (17.4% vs. 18.7%, P=0.7477) and the rate of microbiologically confirmed catheter associated infections were similar (1.4% vs. 1.9%, P=0.7521), the coated CVC showed a significantly lower incidence of BSI (2.0% vs. 6.5%, P=0.0081) and a significantly lower mean incidence of BSI per 1000 catheter days (3.2 vs. 8.3, P=0.0356). CONCLUSION: The non-leaching antibacterial coating of the protective catheter was effective in reducing the incidence of BSI but not the rate of catheter colonization. However, the incidence of BSI is a better surrogate marker for the risk of developing clinical signs of infection suggesting that use of the non-leaching protective catheter is effective in this regard.

Úvod: Metabolický syndrom patří mezi závažný celosvětový společenský problém. V České republice trpí tímto onemocněním více než 30 % dospělé populace. Role rekurentní akutní pankreatitidy v indukci pankreatitidy chronické, ve shodě s mechanistickou definicí chronické pankreatitidy, byla jednoznačně potvrzena. Existuje však řada faktorů, které mohou přispět k rozvoji chronické pankreatitidy. Prvním cílem studie bylo zjistit, zda metabolický syndrom může mít vliv na rozvoj chronické pankreatitidy. Druhou otázku jsme si položili, zda i jedna prodělaná ataka pankreatitidy akutní, může být vyvolávající faktor pankreatitidy chronické. Metody: Na základě retrospektivně získaných dat celkem od 264 osob, které jsou dispenzarizovány s diagnózou chronické pankreatitidy ve 4 centrech, byl získán soubor celkem 59 osob (22,3 %) s chronickou pankreatitidou diagnostikovanou do 36 měsíců od prvé ataky pankreatitidy akutní. Vyloučena byla etiologie pankreatitidy geneticky indukované a pankreatitidy autoimunitní. Ze získaného souboru 59 osob byla provedena diagnostika metabolického syndromu na základě splnění kritérií tzv. harmonizované definice z roku 2009 (obezita, arteriální hypertenze, hypertriglyceridémie, diabetes mellitus 2. typu a snížená hladina HDL cholesterolu). Výsledky: Při porovnání nálezů jednotlivých komponent metabolického syndromu u osob s chronickou pankreatitidou po 1. atace akutní pankreatitidy s metabolickým syndromem a u osob s chronickou pankreatitidou po 1. atace akutní pankreatitidy bez metabolického syndromu, byl nalezen statisticky významný rozdíl v zastoupení obezity (82,5 % v.s. 28,5 %), hypertriglyceridémie (82,3 % v.s. 17,8 %) a arteriální hypertenze (70,5 % v.s. 21,4 %). Interval, během kterého došlo ke vzniku chronické pankreatitidy po akutní pankreatitidě, u osob s metabolickým syndromem činila průměrná doba 12 měsíců (10–14 měsíců), zatímco u skupiny bez přítomnosti metabolického syndromu byl časový interval delší, činil 20 měsíců (16–29 měsíců). Závěr: Naše výsledky ukazují, že i jedna ataka akutní pankreatitidy (bez ohledu na etiologii), může být vyvolávajícím faktorem pankreatitidy chronické. Přítomnost metabolického syndromu může akcelerovat rozvoj chronické pankreatitidy po prodělané pankreatitidě akutní.
Background: Metabolic syndrome is a serious societal problem worldwide. In the Czech Republic more than 30% of the adult population are sufferers. The role of recurrent acute pancreatitis in the induction of chronic pancreatitis, following the so‑called „mechanistic definition“ of chronic pancreatitis, has been unequivocally confirmed. However, there are a number of factors that may contribute to the development of chronic pancreatitis. The first aim of the study was to determine whether the metabolic syndrome may affect the development of chronic pancreatitis. The second question we asked ourselves was whether even one acute attack of pancreatitis could be an inductive factor in chronic pancreatitis. Methods: Based on data obtained retrospectively from a total of 264 people diagnosed with chronic pancreatitis in 4 centers, a total of 59 people (22.3%) diagnosed within 36 months of a first attack of acute pancreatitis was obtained. Etiologies of either genetically induced pancreatitis or autoimmune pancreatitis were excluded. Diagnostics to identify the presence of metabolic syndrome were run on the 59 persons so obtained using the criteria from the so‑called "harmonized" definition of 2009 (obesity, arterial hypertension, hypertriglyceridemia, type 2 diabetes mellitus and a decreased level of HDL cholesterol). Results: Comparing the findings of the individual components of metabolic syndrome in persons with chronic pancreatitis after a 1st attack of acute pancreatitis with the metabolic syndrome and in persons with chronic pancreatitis after the 1st attack of acute pancreatitis but without metabolic syndrome, a statistically significant difference in obesity was found (82.5% vs. 28.5%), hypertriglyceridemia (82.3% vs 17.8%) and arterial hypertension (70.5% vs 21.4%). The interval during which chronic pancreatitis occurred after acute pancreatitis averaged 12 months (10–14 months) in subjects with metabolic syndrome, whereas in the group without metabolic syndrome the interval was longer, 20 months (16–29 months). Conclusion: Our results show that even one attack of acute pancreatitis (regardless of etiology) can be an inductive factor in chronic pancreatitis. The presence of metabolic syndrome can accelerate the development of chronic pancreatitis after one has had acute pancreatitis.
Identification of changes of phospholipid (PL) composition occurring during colorectal cancer (CRC) development may help us to better understand their roles in CRC cells. Here, we used LC-MS/MS-based PL profiling of cell lines derived from normal colon mucosa, or isolated at distinct stages of CRC development, in order to study alterations of PL species potentially linked with cell transformation. We found that a detailed evaluation of phosphatidylinositol (PI) and phosphatidylserine (PS) classes allowed us to cluster the studied epithelial cell lines according to their origin: i) cells originally derived from normal colon tissue (NCM460, FHC); ii) cell lines derived from colon adenoma or less advanced differentiating adenocarcinoma cells (AA/C1, HT-29); or, iii) cells obtained by in vitro transformation of adenoma cells and advanced colon adenocarcinoma cells (HCT-116, AA/C1/SB10, SW480, SW620). Although we tentatively identified several PS and PI species contributing to cell line clustering, full PI and PS profiles appeared to be a key to the successful cell line discrimination. In parallel, we compared PL composition of primary epithelial (EpCAM-positive) cells, isolated from tumor and adjacent non-tumor tissues of colon cancer patients, with PL profiles of cell lines derived from normal colon mucosa (NCM460) and from colon adenocarcinoma (HCT-116, SW480) cells, respectively. In general, higher total levels of all PL classes were observed in tumor cells. The overall PL profiles of the cell lines, when compared with the respective patient-derived cells, exhibited similarities. Nevertheless, there were also some notable differences in levels of individual PL species. This indicated that epithelial cell lines, derived either from normal colon tissue or from CRC cells, could be employed as models for functional lipidomic analyses of colon cells, albeit with some caution. The biological significance of the observed PL deregulation, or their potential links with specific CRC stages, deserve further investigation.

Aim of this pilot study was to assess blood perfusion of bowel in resection lines by means of the infrared thermal imaging in order to choose the best place for anastomosis. The paper brings a first experience with infrared thermal imaging used in colorectal surgery operation from initial observation of the patient with T3 adenomatous carcinoma with no lymph node metastasis. The obtained infrared images show a clear boundary between parts of the intestine with blood perfusion and without it. The proposed position of resection of colon identified by infrared camera is in accordance with routinely designated position. Infrared thermal imaging seems to be a complimentary diagnostic method to see the perfusion in colorectal surgery.

INTRODUCTION: This study aimed to investigate the possible benefits of a complete cytoreduction in patients with advanced ovarian cancer and concomitant rectal invasion. Furthermore, we evaluated the morbidity associated with radical surgery. MATERIAL AND METHODS: A retrospective analysis examined 35 women who underwent radical surgery in the form of modified posterior pelvic exenteration. Descriptive statistics, Kaplan-Meier survival curves and log-rank test were used for statistical estimations. Surgical complications were analyzed using the Clavien-Dindo classification. RESULTS: The analysis of survival in relation to residual disease assessed according to Sugarbaker confirmed an optimistic prognosis in patients with optimal debulking with a mean disease-free survival period of 33.6 months in R0 patients, 19.6 months in R1 patients, and 14.3 months in R2 patients. A statistically significant difference in disease-free survival (p = 0.023) was observed between the R0 (without residual disease) and R1+2 (with residual disease) groups. Surgical complications occurred in 83% of patients, with early postoperative complications being most frequent (65.7%). While grade III-IV complications occurred in 37.7% of all patients, no cases of surgery-associated mortality occurred. CONCLUSIONS: Modified posterior pelvic exenteration is a highly effective method for achieving optimal debulking in cases of advanced ovarian cancer with the direct invasion of the rectum. Modified posterior pelvic exenteration does not delay the beginning of complementary chemotherapy. However, it is necessary to take into account surgery-related morbidity. As modified posterior pelvic exenteration represents an extremely invasive technique, the surgical plan and perioperative care should be personalized to address the individual medical and surgical conditions of each patient.
