[PMID: 39670016 PMCID: PMC11632432 DOI: 10.21037/tlcr-24-448] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2024] [Accepted: 08/20/2024] [Indexed: 12/14/2024]
Abstract
Background Despite the decrease of morbidity rate of non-small cell lung cancer (NSCLC) in recent years, it is still a cancer with poor prognosis. Lung cancers (LCs) are usually diagnosed at a late stage of the disease due to non-specific clinical symptoms. Proper regulation of carnitine levels is important in the context of development and increased risk of cancer cells proliferation. The expression profiles and clinical value of SLC family members in LC remain largely unexplored. The aim of the study was the assessment of SLC22A16, SLC22A5 and SLC6A14 mRNA expression level among patients suffering from NSCLC. The obtained results were compared with the clinical and the pathological features of NSCLC patients. Methods Through reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and bioinformatics studies, the evaluation of carnitine transporting genes (SLC22A16, SLC22A5 and SLC6A14) mRNA levels was performed in order to elucidate their connection to clinical features of patients and influence on overall survival (OS). Results The analysis showed a significant difference for the SLC22A5 gene of NSCLC patients and for SLC6A14 and SLC22A5 genes in LUSC patients in terms of sex (P=0.002, P=0.02 and P=0.001, respectively) and in terms of tobacco smoking (P=0.04). Analysis also revealed a significant negative correlation for SLC22A5 and SLC22A16 genes expression level in the lung adenocarcinoma (LUAD) subtype with standardized uptake value (SUV) (r=-0.40, P=0.02 and r=-0.43, P=0.04). The significant downregulation of gene expression compared to normal adjacent tissue was observed for SLC22A5 in lung squamous cell carcinoma (LUSC) and for SLC6A14 in both LUAD and LUSC subtypes. The effect of the SLC22A5, SLC22A16 and SLC6A14 gene expression at the time of diagnosis on the OS time of LC patients revealed that lower expression correlated with a shorter 5 years OS (all P values <0.01). The effects were distinct after division for LUAD and LUSC subtypes. Conclusions The expression levels of genes encoding carnitine transporters are diverse, hinting at a potentially altered carnitine metabolism in LC patients. Notably, this variance is not uniform and exhibits specificity across LC subtypes, with marked distinctions between LUAD and LUSC. The correlation between gene expression levels and OS of patients underlines the prognostic significance of SLC genes within these cancer subtypes.

Effect of mowing versus abandonment of mesic grasslands in Central Europe on biomass use for biogas production: Implications for semi-natural ecosystem conservation. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2024; 368:122132. [PMID: 39128343 DOI: 10.1016/j.jenvman.2024.122132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/11/2024] [Revised: 08/06/2024] [Accepted: 08/06/2024] [Indexed: 08/13/2024]
Abstract
The economic management of lignocellulosic biomass from semi-natural grasslands is now a challenge across Europe. The abandonment of mowing these grasslands leads to the gradual degradation of these ecosystems. This study investigates how chemical and biological factors affect the suitability of biomass from abandoned grasslands for biogas production. We sampled 30 mown and 30 abandoned grassland sites in the Sudetes Mountains (Poland and Czechia). The cover contribution of short herbs was found to be significantly higher in mown grasslands (p < 0.001), while that of tall herbs was more prevalent in abandoned grasslands (p < 0.01). The specific biogas yield (SBY, NL kg-1 volatile solids) is negatively affected by an increased percentage of herbs in the biomass of mown and abandoned grasslands. This is due to the inhibitory effect of herbs on biodegradation, the increase in lignin content and the decrease in cellulose. This study highlights the importance of individual plant species in assessing grassland biomass for area biogas yield (ABY, m3 ha-1) and provides new insights into a field that has not yet been extensively investigated. In mown grasslands, ABY was most positively correlated with grass species (Arrhenatherum elatius, Trisetum flavescens and Festuca pratensis). In abandoned grasslands, the ABY was most correlated with herbaceous species (Galium aparine, Urtica dioica and Chaerophyllum aromaticum) and grasses (A. elatius and Elymus repens). Mown grasslands had significantly higher species richness (p < 0.001) compared to abandoned grasslands, but the number of species sampled did not correlate with SBY and ABY. This study contributes to the development of a sustainable bio-economy by highlighting the need for efficient use of grassland biomass. This approach helps protect semi-natural ecosystems and facilitates sustainable management of renewable resources.

Abstract
In lung cancer patients, two complementary abnormalities were found that can cause disruption of the mitochondrial network: increased fusion and impaired fission, manifested by reduced levels of FIS1, a mitochondrial division regulator, and increased expression of MFN1, a mitochondrial fusion mediator. Immunoexpression studies of MFN1 and FIS1 proteins were performed in serum samples obtained from 47 patients with non-small cell lung cancer (NSCLC) and 21 controls. In the NSCLC patients, the immunoexpression of the MFN1 protein was significantly higher, and the FIS1 protein level was significantly lower than in the control group (p < 0.01; p < 0.001; UMW test). Patients with early, operable lung cancer had significantly lower levels of MFN1 immunoexpression compared to patients with advanced, metastatic lung cancer (p < 0.05; UMW test). This suggests that early stages of the disease are characterized by greater fragmentation of damaged mitochondria and apoptosis. In contrast, lower FIS1 protein levels were associated with a worse prognosis. Increased mitochondrial fusion in the blood of lung cancer patients may suggest an increase in protective and repair mechanisms. This opens up questions about why these mechanisms fail in the context of existing advanced cancer disease and is a starting point for further research into why protective mechanisms fail in lung cancer patients.

Two-Dimensional Plasma Soft X-ray Radiation Imaging System: Optimization of Amplification Stage Based on Gas Electron Multiplier Technology. SENSORS (BASEL, SWITZERLAND) 2024; 24:5113. [PMID: 39204809 PMCID: PMC11359351 DOI: 10.3390/s24165113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/20/2024] [Revised: 07/17/2024] [Accepted: 07/22/2024] [Indexed: 09/04/2024]
Abstract
The objective of the proposed research is to develop plasma soft X-ray (SXR) radiation imaging that includes spectral information in addition to standard SXR tomography for the purpose of studying, for example, tungsten transport and its interplay with magnetohydrodynamics (MHD) in tokamak plasmas in an ITER-relevant approach. The SXR radiation provides valuable information about both aspects, particularly when measured with high spatial and temporal resolution and when tomographic reconstructions are performed. The spectral data will facilitate the tracking of both light and high-Z impurities. This approach is pertinent to both the advancement of a detailed understanding of physics and the real-time control of plasma, thereby preventing radiative collapses. The significance of this development lies in its ability to provide three-dimensional plasma tomography, a capability that extends beyond the scope of conventional tomography. The utilization of two-dimensional imaging capabilities inherent to Gas Electron Multiplier (GEM) detectors in a toroidal view, in conjunction with the conventional poloidal tomography, allows for the acquisition of three-dimensional information, which should facilitate the study of, for instance, the interplay between impurities and MHD activities. Furthermore, this provides a valuable opportunity to investigate the azimuthal asymmetry of tokamak plasmas, a topic that has rarely been researched. The insights gained from this research could prove invaluable in understanding other toroidal magnetically confined plasmas, such as stellarators, where comprehensive three-dimensional measurements are essential. To illustrate, by attempting to gain access to anisotropic radiation triggered by magnetic reconnection or massive gas injections, such diagnostics will provide the community with enhanced experimental tools to understand runaway electrons (energy distribution and spatial localization) and magnetic reconnection (spatial localization, speed…). This work forms part of the optimization studies of a detecting unit proposed for use in such a diagnostic system, based on GEM technology. The detector is currently under development with the objective of achieving the best spatial resolution feasible with this technology (down to approximately 100 µm). The diagnostic design focuses on the monitoring of photons within the 2-15 keV range. The findings of the optimization studies conducted on the amplification stage of the detector, particularly with regard to the geometrical configuration of the GEM foils, are presented herein. The impact of hole shape and spacing in the amplifying foils on the detector parameters, including the spatial size of the avalanches and the electron gain/multiplication, has been subjected to comprehensive numerical analysis through the utilization of Degrad (v. 3.13) and Garfield++ (v. bd8abc76) software. The results obtained led to the identification of two configurations as the most optimal geometrical configurations of the amplifying foil for the three-foil GEM system for the designed detector. The first configuration comprises cylindrical holes with a diameter of 70 μm, while the second configuration comprises biconical holes with diameters of 70/50/70 μm. Both configurations had a hole spacing of 120 μm.

Abstract
A thorough study of the exosomal proteomic cargo may enable the identification of proteins that play an important role in cancer development. The aim of this study was to compare the protein profiles of the serum exosomes derived from non-small lung cancer (NSCLC) patients and healthy volunteers (control) using the high-performance liquid chromatography coupled to mass spectrometry (HPLC-MS) method to identify potentially new diagnostic and/or prognostic protein biomarkers. Proteins exclusively identified in NSCLC and control groups were analyzed using several bioinformatic tools and platforms (FunRich, Vesiclepedia, STRING, and TIMER2.0) to find key protein hubs involved in NSCLC progression and the acquisition of metastatic potential. This analysis revealed 150 NSCLC proteins, which are significantly involved in osmoregulation, cell-cell adhesion, cell motility, and differentiation. Among them, 3 proteins: Interleukin-34 (IL-34), HLA class II histocompatibility antigen, DM alpha chain (HLA-DMA), and HLA class II histocompatibility antigen, DO beta chain (HLA-DOB) were shown to be significantly involved in the cancer-associated fibroblasts (CAFs) and tumor-associated macrophages (TAMs) infiltration processes. Additionally, detected proteins were analyzed according to the presence of lymph node metastasis, showing that differences in frequency of detection of protein FAM166B, killer cell immunoglobulin-like receptor 2DL1, and olfactory receptor 52R1 correlate with the N feature according to the TNM Classification of Malignant Tumors. These results prove their involvement in NSCLC lymph node spread and metastasis. However, this study requires further investigation.

Abstract
The C-C motif ligand 20 (CCL20) is a chemokine that specifically binds to the chemokine receptor 6 (CCR6) and the CCL20/CCR6 axis has been implicated in the non-small lung cancer (NSCLC) development and progression. Its expression is regulated by mutual interactions of non-coding RNAs (ncRNAs). This goals of presented study was to evaluate the expression level of CCR6/CCL20 mRNA in NSCLC tissue comparative to selected ncRNAs: miR-150, linc00673. The expression level of the studied ncRNAs was also assessed in serum extracellular vesicles (EVs). Thirty patients (n = 30) were enrolled as the study cohort. Total RNA was isolated from tumor tissue, adjacent macroscopically unchanged tissue and serum EVs. The expression level of studied genes and ncRNAs were estimated based on the qPCR method. Higher expression level of CCL20 mRNA but lower expression level of CCR6 mRNA were observed in tumor in comparison to control tissue. Relative to the smoking status, higher CCL20 (p < 0.05) and CCR6 mRNA (p > 0.05) expression levels were observed in current smokers than in never smokers. In serum EVs the expression level of miR-150 has a negative correlation with AJCC tumor staging, whereas the expression level of linc00673 positively correlated (p > 0.05). The lower expression level of miR-150 and higher expression level of linc00673 in serum EVs were observed in NSCLC patients with lymph nodes metastases (p > 0.05). Regarding the histopathological type, significantly lower expression level of miR-150 and higher expression level of linc00673 were observed in the serum EVs of patients with AC compared to patient with SCC. Our findings revealed that smoking significantly changed the expression level of CCL20 mRNA in NSCLC tissue. Changes in expression levels of miR-150 and linc00673 in the serum EVs of NSCLC patients in relation to presence of lymph node metastases and the stage of cancer development may serve as a non-invasive molecular biomarkers of tumor progression. Furthermore, expression levels of miR-150 and linc00673 may serve as non-intrusive diagnostic biomarkers differentiating adenocarcinoma from squamous cell carcinoma.

Abstract
Lung cancer is one of the most common neoplasms globally, with about 2.2 million new cases and 1.8 million deaths annually. Although the most important factor in reducing lung cancer risk is lifestyle change, most patients favour the use of supplements, for example, rather than quitting smoking or following a healthy diet. To better understand the efficacy of such interventions, a systematic review was performed of data from randomized controlled trials concerning the influence of beta-carotene supplementation on lung cancer risk in subjects with no lung cancer before the intervention. The search corpus comprised a number of databases and eight studies involving 167,141 participants, published by November 2021. The findings indicate that beta-carotene supplementation was associated with an increased risk of lung cancer (RR = 1.16, 95% CI = 1.06-1.26). This effect was even more noticeable among smokers and asbestos workers (RR = 1.21, 95% CI = 1.08-1.35) and non-medics (RR = 1.18, 95% CI = 1.07-1.29). A meta-regression found no relationship between the beta-carotene supplementation dose and the size of the negative effect associated with lung cancer risk. Our findings indicate that beta-carotene supplementation has no effect on lung cancer risk. Moreover, when used as the primary chemoprevention, beta-carotene may, in fact, increase the risk of lung cancer.

Abstract
Background One of serious problems in the management of health care units is rational management of financial resources allocated by the government for health care. This management is significantly influenced by the valuation tariff of health care services, including surgical procedures. The assessment of the cost-effectiveness of a particular service has a key role in the selection of procedures performed in a given health care unit. The aim of the study is to assess the costs of lobectomy via thoracotomy and video-assisted thoracoscopic surgery (VATS) in terms of the impact on the overall hospitalization cost and the answer to the question whether differences in hospitalization costs depending on the access are large enough to justify different valuation tariffs for surgery via traditional and minimally invasive access. Methods This is a retrospective analysis of data on the costs of treatment of patients who underwent lobectomy via traditional access or VATS due to non-small cell lung cancer. Data concerning valuation of the procedure and hospitalization were compared with general costs of hospital treatment of these patients. Results The study has proven that duration of the procedure (VATS: 145 min, thoracotomy: 143 min) and total value of hospitalization costs depending on the type of access (VATS: €2,235, thoracotomy: €1,500) were similar-the differences did not show statistical significance (P=0.96 and 0.05118). In contrast, the average time of patient stay in the hospital after surgery and the average cost of surgery were significantly different (3.69 for VATS vs. 5.71 days for thoracotomy with P=0.0000084 and €1,705 for VATS and €682 for thoracotomy with P=0.0114). Conclusions The total cost of patient hospitalization after lobectomy via VATS is similar to the cost of hospitalization after thoracotomy. Similar costs of both treatments with well-known benefits of VATS including shorter hospitalization and better quality of life of the patient speak in favor of a wider use of minimally invasive access with a good effect in the form of economical use of financial resources.

Abstract
Duodenal perforation is a rare and severe acute surgical condition which commonly follows the complications of endoscopic and laparoscopic procedures. Small degree of damage in this mechanism and an early diagnosis allow for an effective primary management. The most difficult surgical challenge is an effective management of retroperitoneal duodenal perforation together with coexisting pathological changes of its wall. In this work we present a case of duodenal necrosis with excessive necrosis of a fragment of its wall due to perinephric abscess, with an effective method of management of a defect in an isolated free small intestinal loop in association with gastroduodenal passage exclusion.

Abstract
The paper reports on the optimization process of the soft X-ray pulse height analyzer installed on the Wendelstein 7-X (W7-X) stellarator. It is a 3-channel system that records X-ray spectra in the range from 0.6 to 19.6 keV. X-ray spectra, with a temporal and spatial resolution of 100 ms and 2.5 cm (depending on selected slit sizes), respectively, are line integrated along a line-of-sight that crosses near to the plasma center. In the second W7-X operation phase with a carbon test divertor unit, light impurities, e.g., carbon and oxygen, were observed as well as mid- to high-Z elements, e.g., sulfur, chlorine, chromium, manganese, iron, and nickel. In addition, X-ray lines from several tracer elements have been observed after the laser blow-off injection of different impurities, e.g., silicon, titanium, and iron, and during discharges with prefill or a gas puff of neon or argon. These measurements were achieved by optimizing light absorber-foil selection, which defines the detected energy range, and remotely controlled pinhole size, which defines photon flux. The identification of X-ray lines was confirmed by other spectroscopic diagnostics, e.g., by the High-Efficiency XUV Overview Spectrometer, HEXOS, and high-resolution X-ray imaging spectrometer, HR-XIS.

Abstract
The vast biodiversity of the microbial world and how little is known about it, has already been revealed by extensive metagenomics analyses. Our rudimentary knowledge of microbes stems from difficulties concerning their isolation and culture in laboratory conditions, which is necessary for describing their phenotype, among other things, for biotechnological purposes. An important component of the understudied ecosystems is methanogens, archaea producing a potent greenhouse-effect gas methane. Therefore, we created PhyMet2 , the first database that combines descriptions of methanogens and their culturing conditions with genetic information. The database contains a set of utilities that facilitate interactive data browsing, data comparison, phylogeny exploration and searching for sequence homologues. The most unique feature of the database is the web server MethanoGram, which can be used to significantly reduce the time and cost of searching for the optimal culturing conditions of methanogens by predicting them based on 16S RNA sequences. The database will aid many researchers in exploring the world of methanogens and their applications in biotechnological processes. PhyMet2 with the MethanoGram predictor is available at http://metanogen.biotech.uni.wroc.pl.

Abstract
Background Assessment of serum extracellular matrix (ECM) metalloproteinase MMP-2 and tissue inhibitor of matrix metalloproteinase TIMP-2 concentrations in non-small cell lung carcinoma (NSCLC) patients considering TNM staging. Assessment of the prognostic value of MMP-2 and TIMP-2 concentrations in NSCLC patients. Methods The study group consisted of 81 NSCLC patients (24 females and 57 males) aged 46 to 86 years (mean age of 67±8.2 years). The control group comprised 39 randomly selected patients (20 females and 19 males) aged 27 to 73 years (mean age of 47±15.0 years) in whom primary lung cancer was excluded and who were operated on for a calculus of the gallbladder without cholecystitis. Blood serum MMP-2 and TIMP-2 concentrations were determined using an enzyme-linked immunosorbent assay (ELISA)-based test. Results Statistically significantly higher mean MMP-2 and TIMP-2 concentrations were found in NSCLC patients compared to those in the control group (P<0.001). Statistically significant differences in MMP-2 and TIMP-2 concentrations between patients with T1 and T2 tumour and patients with T3 and T4 tumour, as well as between the group without metastases (N0) and the group with metastases to lymph nodes were demonstrated. Moreover, a significant fall in mean MMP-2 and TIMP-2 concentrations was observed in the postoperative compared to preoperative period (P<0.001). Conclusions Serum MMP-2 and TIMP-2 concentrations in NSCLC patients correlated with the tumour size and presence of metastases to lymph nodes and thus may serve as an auxiliary parameter indicating probability of a more advanced stage of lung cancer.

Abstract
Background: Esophageal perforation is a life-threatening condition of a complex etiology. No clear guidelines are available regarding the management of this condition. In this study, we review publications related to esophageal perforation, and analyze patients treated for this condition at our Department of Thoracic, General and Oncological Surgery. Objective: The objective of the study was to retrospectively assess and analyze management methods for esophageal perforations of different etiologies. All patients were treated in the Department of Thoracic, General and Oncological Surgery in years 2009-2015. Patients with perforations resulting from post-operational leaks within surgical anastomoses were excluded from the study. Material, methods, results: The analysis involved a total of 16 cases of esophageal ruptures. All cases were treated in years 2009-2015. Patients with perforations resulting from postoperative leaks within surgical anastomoses following elective surgeries for either oncological or non-oncological causes were excluded. The most common reason for esophageal rupture was iatrogenic injury (7 cases, 44%). Other causes included Boerhaave syndrome (5 cases, 31.2%), blunt trauma (2 cases, 12.5%), abscess perforation (1 case, 6.2%), and ulcer perforation (1 case, 6.2%). Ten patients underwent surgery, and the rest underwent esophageal prosthesis placement, of whom 2 cases required drainage of the mediastinum and pleural cavity. The mortality rate in the study group was 9/16 cases (56.2%). Conclusions: Esophageal perforation poses a significant interdisciplinary challenge regarding diagnostic workup, selection of treatment methods, and management of potential postoperative complications. This retrospective study was conducted in a single center. Although the analyzed period was long, we found only 16 cases. In spite of a variety of etiologies present, we found several statistically significant results of potential clinical value. 1. Most perforations that are not diagnosed within 48 hours affected the lower part of the esophagus and presented with unclear symptoms and imaging findings 2. Delaying diagnosis and treatment beyond 24 hours was associated with a higher mortality rate.

Abstract
Introduction Resection of manubrium or body of the sternum is associated with a necessity of chest wall reconstruction. Large sternal defects require the use of different types of implants to ensure acceptable esthetic effect for the patient and chest stabilization. Aim The purpose of this case report is to present a novel method of reconstruction of manubrium removed due to renal cancer metastasis to the sternum. Case We present the case of a patient, who had underwent right nephrectomy for clear cell kidney cancer, diagnosed with a metastatic tumor in the sternum resulting in destruction of manubrium. The patient undergone tumor resection with primary reconstruction with an individual prosthesis. Sternal defect was filled with a personalized, computed tomography scan-based 3D-milled implant made of polyethylene. Results Sternal reconstruction was uneventful. The patient endured surgery well, and has been under surveillance in outpatient clinic, without any respiration disorders, implant movement or local recurrence. Conclusion Custom-designed sternal implants created by 3D technique constitute an interesting alternative for previous methods of filling defects after resection of a tumor in this location.

Enhancing biogas plant production using pig manure and corn silage by adding wheat straw processed with liquid hot water and steam explosion. BIOTECHNOLOGY FOR BIOFUELS 2017; 10:259. [PMID: 29151888 PMCID: PMC5679381 DOI: 10.1186/s13068-017-0922-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/15/2017] [Accepted: 10/03/2017] [Indexed: 05/03/2023]
Abstract
BACKGROUND Pig manure utilization and valorization is an important topic with tightening regulations focused on ecological and safety issues. By itself pig manure is a poor substrate for biogas production because of its excessive nitrogen content relative to available organic carbon. Such substrate is alkaline, and methanogenesis can be suppressed, and so additional substrates with high organic carbon must be added. The most promising is straw, which is available from adjacent biogas plant cultures. However, the abundant lignocellulosic biomass of wheat straw undergoes slow decomposition, and only a fraction of the chemical energy can be converted into biogas; thus economical methods for pretreatment increasing bioavailability are sought. RESULTS A method was investigated to increase the methane yield in a full-scale plant for co-fermenting pig manure with corn silage, which was the default substrate in the original source reactors. Increased lignocellulosic bioavailability of wheat straw was achieved by combining liquid hot water (LHW) and steam explosion (SE). According to FT-IR analysis, the treatment resulted in hemicellulose hydrolysis, partial cellulose depolymerization, and lignin bond destruction. Low-mass polysaccharides (0.6 × 103 g mol-1) had significantly higher concentration in the leachate of LHW-SE wheat straw than raw wheat straw. The methanogenic potential was evaluated using inoculum from two different biogas plants to study the influence of microorganism consortia. The yield was 24-34% higher after the pretreatment process. In a full-scale biogas plant, the optimal conditions were ~ 165 °C, ~ 2.33 MPa, and 10 min in LHW and ~ 65 °C and ~ 0.1 MPa for SE. The processes did not generate detectable inhibitors according to GC-MS analysis, such as furfural and 5-hydroxymethylfurfural. CONCLUSIONS The LHW-SE combined pretreatment process increases the bioavailability of carbohydrates from wheat straw. The LHW-SE treated wheat straw gave similar biogas yields to corn silage, thus enables at least partial replacement of corn silage and is good for diversification of substrates. Surprisingly, microorganisms consortia from other biogas plant fed with other substrates may have higher efficiency in utilization of tested substrate. Thus, methanogenic consortia may be considered in the process of optimization at industrial scale. The efficiency was calculated, and the LHW-SE may be profitable at full industrial scale and further optimization is proposed.

Abstract
Wendelstein 7-X, a superconducting optimized stellarator built in Greifswald/Germany, started its first plasmas with the last closed flux surface (LCFS) defined by 5 uncooled graphite limiters in December 2015. At the end of the 10 weeks long experimental campaign (OP1.1) more than 20 independent diagnostic systems were in operation, allowing detailed studies of many interesting plasma phenomena. For example, fast neutral gas manometers supported by video cameras (including one fast-frame camera with frame rates of tens of kHz) as well as visible cameras with different interference filters, with field of views covering all ten half-modules of the stellarator, discovered a MARFE-like radiation zone on the inboard side of machine module 4. This structure is presumably triggered by an inadvertent plasma-wall interaction in module 4 resulting in a high impurity influx that terminates some discharges by radiation cooling. The main plasma parameters achieved in OP1.1 exceeded predicted values in discharges of a length reaching 6 s. Although OP1.1 is characterized by short pulses, many of the diagnostics are already designed for quasi-steady state operation of 30 min discharges heated at 10 MW of ECRH. An overview of diagnostic performance for OP1.1 is given, including some highlights from the physics campaigns.

Abstract
BACKGROUND AND AIMS Prolonged air leaks (PAL) are a common problem after pulmonary resection. PAL can be a source of significant complications. One of the treatment options is chemical pleurodesis. MATERIAL AND METHODS The efficiency of three methods of treatment of PAL after lung resection was evaluated. In Iodine_ group aqueous iodine solution (lat.Tinctura Jodi) was applied intrapleurally (30 patients); in Doxycycline_group (34 patients) 200 mg of Doxycyclin was given and in Drainage_group 35 patients were applied Lidocaine solution only. RESULTS The group investigated was similar with regard to age [F = 0.04, P = 0.96] and the amount of air leakage (approx. 462 mL/min). The shortest drainage time and hospital stay was observed in the Iodine_group [10.57, P < 0.001]. However, this therapy was connected with strongly perceptible chest pain (P < 0.0001]). The number of case of pneumothorax recurrence was low and it was the same was seen in other methods of treatment [F = 0.87, P = 0.42]. Allergic reactions were not observed. The number of episodes of tachycardia, hypotension, dyspnea, pneumonia, subcutaneus empyema, fluid collection, emphysema, pneumothorax recurrence and number of re-thoracotomies were statistically similar in all three methods of treatment. CONCLUSION Iodine pleurodesis can be considered as one of possible treatment methods of PAL after lung resection as it showed favorable results compared with Doxycycline pleurodesis or drainage alone regarding duration of air leakage, hospitalization and pneumothorax recurrence with only slightly increased pleural pain.

Abstract
UNLABELLED The cholecystectomy procedure is the most routinely performed intervention in general surgery. The current international gold standard is via the laparoscopic approach. It is a safe, minimally-invasive procedure; however, it is associated with complications in 1% of cases. The aim of the study was to analyze patient feedback, by means of a survey, to determine how much knowledge patients possessed about their disease state and proposed surgical intervention, based primarily on information contained within the informed consent form developed by the Association of Polish Surgeons. MATERIAL AND METHODS This study involved the participation of 51 patients who underwent laparoscopic cholecystectomy, indicated by a diagnosis of gallstones, in the years 2014 and 2015. RESULTS Despite having signed the informed consent form, there was considerable variation among the responses given to the survey by the 51 patients in this study. Some patients' responses were tangential to the questions asked; many patients did not respond to any of the sub points. CONCLUSIONS Given that this study is based on a small sample size of patients, it must be presumed that the process by which the patient declares his or her informed consent requires further consideration with respect to the means by which it is obtained. The authors of this study thus recommend that multimedia resources be harnessed as part of the process of obtaining the informed consent of patients prior to surgical intervention.
