ABSTRACT

BACKGROUND: Chest X-ray (CXR) remains the standard imaging modality in postoperative care after non-cardiac thoracic surgery. Lung ultrasound (LUS) showed promising results in CXR reduction. The aim of this review was to identify areas where the evaluation of LUS videos by artificial intelligence could improve the implementation of LUS in thoracic surgery. METHODS: A literature review of the replacement of the CXR by LUS after thoracic surgery and the evaluation of LUS videos by artificial intelligence after thoracic surgery was conducted in Medline. RESULTS: Here, eight out of 10 reviewed studies evaluating LUS in CXR reduction showed that LUS can reduce CXR without a negative impact on patient outcome after thoracic surgery. No studies on the evaluation of LUS signs by artificial intelligence after thoracic surgery were found. CONCLUSION: LUS can reduce CXR after thoracic surgery. We presume that artificial intelligence could help increase the LUS accuracy, objectify the LUS findings, shorten the learning curve, and decrease the number of inconclusive results. To confirm this assumption, clinical trials are necessary. This research is funded by the Slovak Research and Development Agency, grant number APVV 20-0232.

ABSTRACT

OBJECTIVES: This study is aimed to determine the location and distribution of pulmonary embolism (PE) and presence of signs potentially indicative of right heart overload on computed tomography pulmonary angiography (CTPA) in COVID-19 and non-COVID-19 patients. We also evaluated the extent and severity of COVID-19-associated lung changes in relation to PE. METHODS: The total number of 1,698 patients with CTPA included in the study were divided into 2 groups according to their COVID-19 status and each group was divided into 2 subgroups based on their PE status. These groups and subgroups were compared in terms of location of PE, diameter of pulmonary artery, right heart strain, ground-glass opacities (GGO), consolidations and other imaging features. RESULTS: In COVID-19 patients, there was a significant predominance of PE in peripheral branches of pulmonary artery (p < 0.001). There was an increased right-to-left ratio of ventricular diameters in cases with PE (p = 0.032 in patients with COVID-19 and p < 0.001 in non-COVID-19 patients). There was no association between the extent and severity of the disease and distribution of PE. CONCLUSION: COVID-19 is associated with a higher incidence of peripheral location of PE and presence of GGO. There were signs indicative of right heart overload in cases with PE regardless of COVID-19 (Tab. 3, Fig. 1, Ref. 29) Keywords: COVID-19, computed tomography, CTPA, pneumonia, pulmonary embolism.

ABSTRACT

OBJECTIVES: The current retrospective study focused on evaluation of the relationship between pulmonary embolism during COVID-19 pandemic and demographic, presenting symptoms, comorbidities and laboratory results in patients who underwent CT angiography of the pulmonary arteries. METHODS: The study enrolled all adult patients with suspected acute pulmonary embolism (PE) who underwent computed tomography pulmonary angiography (CTPA) between March 1, 2020, and April 30, 2022, during the SARS-CoV-2 pandemic. 1698 CTPAs were reviewed and various data were collected. Based on examination results, patients were divided into 4 groups: a group with positive PE and a group with negative PE for both COVID-19 and non-COVID-19 patients. RESULTS: When comparing different predictors of COVID-19 patients and non-COVID-19 patients we noticed lower probability of PE in female gender (OR 0.77, 95% CI: 0.60-1.00, p = 0.052) and in chronic obstructive pulmonary disease (COPD) patients (OR 0.6, 95% CI: 0.38-0.90, p = 0.017). Higher probability of PE was in cases of older age (OR 1.02, 95% CI: 1.01-1.02, p < 0.001), increased heart rate (OR 1.01, 95% CI: 1.01-1.02, p < 0.001) and increased D-dimer levels (OR 1.03, 95% CI: 1.02-1.04, p < 0.001). CONCLUSION: Considering predictors of PE there was a significantly lower risk of PE in the female gender and COPD, and a higher risk with increasing age, heart rate, and D-dimer levels.

ABSTRACT

Lung carcinoma is the "top killer" of all malignancies in the world. Early diagnosis of lung carcinoma significantly improves patient survival. Screening with biomarkers from peripheral blood could detect more patients at an early stage of the disease. MicroRNAs (miRNAs) could be a possible biomarker. These are 21-23 nucleotide long single-stranded RNA molecules playing an important role in the post-transcriptional regulation of gene activity. Individual miRNAs have the potential to regulate genes responsible for cell proliferation, differentiation, apoptosis, regulate cell cycle in cooperation with pro-oncogenes and tumor suppressor genes. In our study, we determined miRNA expression levels in individual samples of lung carcinoma patients and in a healthy control group. We used the reverse transcription method followed by qRT-PCR. The expression levels of the investigated miRNAs were evaluated in the QIAGEN GeneGlobe Data center software. We demonstrated the significance of miR-126 and let-7g as biomarkers of lung carcinoma in all clinical stages studied. We also observed significantly increased expression of miR-143 and miR-145 at the distant metastasis stage, and significantly decreased expression of miR-133a in the N2 disease group of lung carcinoma patients (N2 disease represents disease with metastases in the ipsilateral mediastinal and/or subcarinal lymph nodes or node). The investigated miRNAs showed no clear potential for detecting potentially resectable (N0-N1), locally advanced (N2) and distant organ metastatic (M1) lung carcinoma.

ABSTRACT

BACKGROUND: Risk for developing papillary thyroid carcinoma (PTC), the most common endocrine malignancy, is thought to be mediated by lifestyle, environmental exposures and genetic factors. Recent progress in the genome-wide association studies of thyroid cancer leads to the identification of several genetic variants conferring risk to this malignancy across different ethnicities. METHODS AND RESULTS: We set out to elucidate the impact of selected single nucleotide polymorphisms (SNPs) on papillary thyroid carcinoma risk and to evaluate the interactions of these genetic variants with associated diseases for the first time in the Slovak population. Six SNPs (rs966423, rs2439302, rs965513, rs116909374, rs1537424 and rs944289) were genotyped in 86 patients with PTC and 99 healthy control subjects. The association analysis and multivariable modelling of PTC risk by the genetic factors, supplemented with a rigorous statistical validation, were performed. One of the six SNPs rs966423 (DIRC3, OR=1.51, p=0.03) was significantly associated with PTC. Next two SNPs rs965513 (PTCSC2, OR=1.34) and rs116909374 (MBIP, OR=0.44) showed a suggestive association. Haplotype TTC (SNPs located on chromosome 14q13) showed a suggestive association with PTC (p=0.07, OR=1.55). In the PTC group, significant associations were observed between rs966423 (DIRC3) and ischemic heart diseases (p=0.009), rs965513 (PTCSC2) and diabetes mellitus (p=0.04) and haplotype 14q13 and musculoskeletal diseases. Next three associations rs966423 (DIRC3) and arterial hypertension; rs116909374 (MBIP) and other benign diseases; rs1537424 (MBIP) and disorder lipid metabolism, rs965513 (PTCSC2) and anti-Tg (thyroglobulin antibody) showed suggestive associations. CONCLUSION: These results indicate that germline variants not only predispose to PTC, but may also be related to other risk factors, including associated diseases. However, these associations were only moderate, and further multi-ethnic studies are required to evaluate the usefulness of these germline variants in the clinical stratification of PTC patients (Tab. 8, Ref. 37).

ABSTRACT

INTRODUCTION: Lung cancer is the leading cause of cancer-related deaths worldwide. For this reason, huge efforts are being invested in discovering suitable blood biomarkers that would allow early diagnosis and treatment. One of the possible promising candidates for this role are microRNA molecules (miRNAs). The aim of the study was to identify individual blood miRNAs that could be used as potential biomarkers for early diagnosis of lung cancer. METHODS: This prospective study analyzed blood samples of 60 patients with early-stage lung cancer, and blood samples of 60 healthy individuals. All study patients with lung cancer had undergone radical pulmonary resection at the University Hospital Ostrava within the study period (2015-2017). Definitive diagnosis of lung cancer was confirmed by histopathology examination of the resected pulmonary specimen. We investigated relative expressions in selected 13 blood miRNAs; the examined miRNAs were miR-126, miR-155, miR-221, miR-21, miR-143, miR-145, miR-133a, let-7a, miR-146a, miR-31, miR-182, let-7g and miR-19b. RESULTS: The outcome of this study showed that the levels of the majority of the tested circulating miRNA in lung cancer patients are significantly altered. The most significant serum miRNA biomarkers for the early detection of lung cancer are as follows: miR-143, let-7g, miR-126, let-7a, and miR-145 (miR-143 and miR-145 have oncogene functions, while miR-126, let-7g and let-7a have suppressor functions). CONCLUSIONS: We have demonstrated the excellent diagnostic value of several miRNAs (miR-126, miR-143, miR-145, let-7a and let7g). These have an estimated sensitivity and specificity of 75-85% and 0.90-0.93 AUC. However, these individual miRNA biomarkers require further validation in larger prospective cohorts.

ABSTRACT

Diffuse pulmonary meningotheliomatosis (DPM) is reported as a diffuse parenchymal lung disease characterized by disseminating small asymptomatic nodules. These lesions are often detected incidentally as microscopic findings in lung specimens or autopsies examined by a pathologist. We report a case of a 60-year-old male asymptomatic patient presenting with multiple bilateral pulmonary nodules on high-resolution computed tomography and diagnosed by videothoracoscopic surgery. Differential diagnosis of patients presenting with diffuse indeterminate nodules is very important. Definitive diagnosis of DPM requires histopathology and most often videothoracoscopic lung biopsy.

ABSTRACT

The global pandemic of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is having a tremendous impact on the global economy, health care systems and the lives of almost all people in the world. The Central European country of Slovakia reached one of the highest daily mortality rates per 100,000 inhabitants in the first 3 months of 2021, despite implementing strong prophylactic measures, lockdowns and repeated nationwide antigen testing. The present study reports a comparison of the performance of the Standard Q COVID-19 antigen test (SD Biosensor) with three commercial RT-qPCR kits (vDetect COVID-19-MultiplexDX, gb SARS-CoV-2 Multiplex-GENERI BIOTECH Ltd. and Genvinset COVID-19 [E]-BDR Diagnostics) in the detection of infected individuals among employees of the Martin University Hospital in Slovakia. Health care providers, such as doctors and nurses, are classified as "critical infrastructure", and there is no doubt about the huge impact that incorrect results could have on patients. Out of 1231 samples, 14 were evaluated as positive for SARS-CoV-2 antigen presence, and all of them were confirmed by RT-qPCR kit 1 and kit 2. As another 26 samples had a signal in the E gene, these 40 samples were re-isolated and subsequently re-analysed using the three kits, which detected the virus in 22, 23 and 12 cases, respectively. The results point to a divergence not only between antigen and RT-qPCR tests, but also within the "gold standard" RT-qPCR testing. Performance analysis of the diagnostic antigen test showed the positive predictive value (PPV) to be 100% and negative predictive value (NPV) to be 98.10%, indicating that 1.90% of individuals with a negative result were, in fact, positive. If these data are extrapolated to the national level, where the mean daily number of antigen tests was 250,000 in April 2021, it points to over 4700 people per day being misinterpreted and posing a risk of virus shedding. While mean Ct values of the samples that were both antigen and RT-qPCR positive were about 20 (kit 1: 20.47 and 20.16 for Sarbeco E and RdRP, kit 2: 19.37 and 19.99 for Sarbeco E and RdRP and kit 3: 17.47 for ORF1b/RdRP), mean Ct values of the samples that were antigen-negative but RT-qPCR-positive were about 30 (kit 1: 30.67 and 30.00 for Sarbeco E and RdRP, kit 2: 29.86 and 31.01 for Sarbeco E and RdRP and kit 3: 27.47 for ORF1b/RdRP). It confirms the advantage of antigen test in detecting the most infectious individuals with a higher viral load. However, the reporting of Ct values is still a matter of ongoing debates and should not be conducted without normalisation to standardised controls of known concentration.

ABSTRACT

Epitheloid haemangiothelioma is extremely rare malignant tumour of vascular origin. Mediastinal location of this neoplasm with large veins involving is not common. We report a case of epitheloid haemangiothelioma in superior vena cava treated by radical resection and superior vena cava replacement with polytetrafluoroethylene prosthetic graft. There is a certain risk of neurological injury during the cross-clamping of superior vena cava in patient with incompletely obstructed veins. Venovenous shunt is a useful surgical strategy in this type of lesion without necessity of cardiopulmonary bypass use.

ABSTRACT

Targeting metabolomic pathways is a promising strategy for cancer treatment. Alterations in the metabolomic state have also an epigenetic impact, making the metabolomic studies even more interesting. We explored metabolomic changes in the blood plasma of patients with primary and secondary lung cancer and tried to explore their origin. We also applied a discrimination algorithm to the data. In the study, blood samples from 132 patients with primary lung cancer, 47 with secondary lung cancer, and 77 subjectively healthy subjects without any cancer history were used. The samples were measured by NMR spectroscopy. PCA and PLS-DA analyses did not distinguish between patients with primary and secondary lung tumors. Accordingly, no significantly changed levels of plasmatic metabolites were found between these groups. When comparing with healthy controls, significantly increased glucose, citrate, acetate, 3-hydroxybutyrate, and creatinine balanced with decreased pyruvate, lactate, alanine, tyrosine, and tryptophan were found as a common feature of both groups. Metabolomic analysis of blood plasma showed considerable proximity of patients with primary and secondary lung cancer. The changes observed can be partially explained as cancer-derived and also as changes showing ischemic nature. Random Forrest discrimination based on the relative concentration of metabolites in blood plasma performed very promising with AUC of 0.95 against controls; however noticeable parts of differencing metabolites are overlapping with those observed after ischemic injury in other studies.

ABSTRACT

BACKGROUND: Roentgenography remains the standard imaging modality after thoracic surgery. Trials from intensive medicine proved a high accuracy of ultrasound examination in the diagnosis of various conditions. The assumption was that ultrasound examination could reduce the number of roentgenograms after thoracic surgery. METHODS: This prospective study compared ultrasound examinations performed by thoracic surgeons with roentgenograms in the diagnosis of pneumothorax and pleural effusion after noncardiac thoracic surgery. Patients received 2 ultrasound scans, the first on the day of surgery and the second before chest tube removal. RESULTS: A total of 297 patients underwent 545 examinations; 336 ultrasound scans (61.6%) showed neither pneumothorax nor pleural effusion. Pneumothorax was detected on 69 roentgenograms and 51 ultrasound scans. Both modalities showed positive results in 32 cases and negative results in 395 cases (Cohen's κ, 53.4%). Ultrasound missed 37 clinically irrelevant pneumothoraces. Roentgenograms missed 19 pneumothoraces; 15 of them were clinically irrelevant. Sensitivity and specificity were 59.4% and 95.9% in the first examination and 50.0% and 94.8% in the second examination, respectively. Pleural effusion was detected on 169 roentgenograms and 117 ultrasound scans. Both modalities showed positive results in 88 cases and negative results in 336 cases (Cohen's κ, 49.6%). Ultrasound scans missed 81 pleural effusions; except for 5 cases, the clinical decisions would not have changed. Roentgenograms missed 29 clinically irrelevant pleural effusions. Sensitivity and specificity were 44.4% and 92.6% in the first examination and 60.9% and 91.3% in the second examination, respectively. CONCLUSIONS: Given high specificities, a large share of results without pneumothorax and pleural effusion, and mismatch analysis, we could reduce the number of roentgenograms by 61.6% by using ultrasound as a primary imaging modality.

ABSTRACT

INTRODUCTION: Scapulothoracic articulation has several bursae which allow a sliding movement of the scapulothoracic joint. The two major anatomical bursae are the supraserratus bursa and infraserratus bursa. PRESENTATION OF CASE: It was a case of a 59 year-old female patient with a professional load and a clinical finding of bilateral subscapular resistances of the thorax. The finding of bilateral collections in the intermuscular spaces between external intercostal muscles and heads of serratus anterior muscle was verified by magnetic resonance. CONCLUSION: Due to progressively increasing bilateral findings an open surgical resection was implemented, with good result.

ABSTRACT

OBJECTIVES: Descending necrotizing mediastinitis (DNM) is a severe potentially fatal disease of the mediastinum which spreads downwards from oropharyngeal region. Mortality varies from 11 to 40%. There is agreement on the importance of early diagnosis, aggressive surgical treatment and the need for a multidisciplinary approach. DESIGN: Retrospective study of series of patient treated for DNM regarding multidisciplinary approach and surgical treatment. PATIENTS AND METHODS: Sixteen patients that were surgically treated for DNM from 2008 to 2017 at our hospital were consecutively enrolled in observational descriptive study. RESULTS: Twelve patients had disease localised above tracheal bifurcation level. Nine of them underwent transcervical drainage, three patients underwent more extensive treatment. Four patients with disease spread below the treacheal bifurcation level were treated with transcervical drainage in combination with posterolateral thoracotomy or videothoracoscopy. Three patients underwent videothoracoscopy - two of them as primary surgical treatment with need of one reoperation - contralateral videothoracoscopy. The third patient was initially treated with a transcervical approach and videothoracoscopy was indicated as a reoperation because of the progression of the disease. One patient died (mortality 6.25%). CONCLUSION: In management of descending necrotizing mediastinitis, early diagnosis, aggressive surgical treatment and use of broad-spectrum antibiotics and nowadays also multidisciplinary approach are crucial. Transcervical drainage combined with posterolateral thoracotomy or videothoracoscopy were used with good results.

ABSTRACT

BACKGROUND: Apoptosis plays an important role in the development and homeostasis of multicellular organisms and its deregulation may result in many serious diseases, including cancer. Now it is clear that some oncogenic mutations disrupt apoptosis, leading to tumour initiation, progression or metastasis. Here, expression of apoptotic genes in context of drug resistance was investigated. METHODS: We examined total of 102 samples from leukemic patients (n = 60) and patients with solid tumours (n = 42). We used RT-PCR to determine the levels of mRNA expression and the in vitro chemoresistance of leukemic cells was evaluated using the MTT assay. RESULTS: We found statistically significant increase in mRNA expression of all investigated proteins (p53, BAX, Bcl-2 and Bcl-XL) between the leukemia samples and leukocytes from healthy volunteers. We did not find any significant difference in mRNA levels among the solid tumour samples. Notably, we showed a significant positive correlation in both leukemic and solid tumour patient groups between p53 and BAX mRNA. We found that the highest values for the Bcl-2/BAX ratio were in solid tumours in comparison to leukemic cells or normal leukocytes. Moreover, we assessed the impact of p53 and BAX mRNA levels on the sensitivity of the leukemic cells to selected cytostatics. CONCLUSIONS: Elevated levels of p53 and BAX mRNA may indicate cellular response to possible changes in genomic DNA integrity associated with malignant transformation. We suggest that the BAX gene is regulated by the p53 protein but the initiation of apoptosis through the transcription activation of BAX is blocked by the high levels of Bcl-2. Given that the apoptosis resistance mechanisms are different among oncological patients as well as stages of identical malignancy cases, personalized and specific combination therapy is proposed to be more effective in clinical application.

ABSTRACT

BACKGROUND: Primary malignant or metastatic sternal tumors are uncommon. A subtotal or total sternectomy can offer a radical form of treatment. The issue is to restore the structural integrity of the chest wall. CASE PRESENTATION: We report the implantation of an individualized 3D-printed titanium sternum in a patient with a sternal tumor. CONCLUSIONS: We believe that tridimensional print technologies may also change the strategy of chest wall reconstruction.

ABSTRACT

The authors present a case report of severe descending necrotizing mediastinitis (DNM) etiologically of unrecognized traumatic endotracheal intubation with hypopharynx-esophageal junction perforation. Patient was treated inadequately for seven days in local hospital what was the cause of sepsis progression into the septic shock with multiorgan dysfunction syndrome. Patient was transferred to specialized hospital and was immediately operated in general anaesthesia - combined transcervical approach and lateral thoracotomy was used for mediastinal drainage and debridement. Combination of appropriate conventional and surgical therapy led to reversing of the unfavorable situation.

ABSTRACT

Dihydropyrimidine dehydrogenase (DPD) acts as the first-step enzyme catabolizing pyrimidines in vivo. DPYD gene mutations interfere with the breakdown of uracil and thymine. Genetic variations of DPYD can cause an enzyme deficiency state, which results in severe toxicity or other adverse side effects such as DNA damage or RNA damage caused by imbalance of the nucleotide pool. Our case-control study investigates the possible association between seven DPYD gene polymophisms (rs1801267, rs72547602, rs1801160, rs3918290, rs1801159, rs1801158, rs1801265) and risk of colorectal cancer (CRC). The association analysis for DPD was performed on 273 CRC patients and 187 healthy controls. There is significant allele association of SNP rs1801160 with colorectal cancer (p = 0.003, OR = 3.264, 95% CI = 1.425-7.475) in present analysis. Haplotype analysis of four DPYD polymorphisms showed significant difference in the distribution "IISt" haplotype between cases and controls. In comparison to the most common haplotype (VISt), the "IISt" haplotype was associated with increased risk for CRC (p = 0.038, OR = 2.733, 95% CI = 1.019-7.326). The present study suggests that the SNP rs1801160 and the "IISt" haplotype in the DPYD gene may also have a role in colorectal cancer risk.

ABSTRACT

Synchronous multiple primary lung cancer (SMPLC) means tumours present at the same time, which are separate and have different histology. We present the case of a 66-year-old patient with a combination of small-cell lung carcinoma (SCLC) with adenocarcinoma in the same lobe with metastasis of SCLC in the mediastinal lymph node. This is a rare case. We performed a standard left upper video-assisted thoracoscopic lobectomy with mediastinal lymphadenectomy and adjuvant therapy targeted to SCLC was administered. Despite advances in imaging methods and diagnostic procedures in pneumology a diagnosis of SMPLC is often discovered only intraoperatively or accidentally during the histological examination. Actually, no guidelines exist for the treatment protocol of such cases. Multiple methods of management of SMPLC, mainly complete anatomical resection with lymphadenectomy combined with chemotherapy or radiotherapy should be adopted according to the histologic types, staging and molecular testing of the tumours. These rare cases of SMPLC require individual treatment and multidisciplinary approach.

ABSTRACT

The authors describe a case of a 36-year-old patient who had six months' pain of the thoracic spine and left chest. A soft slowly growing resistance was present on the dorso-lateral side of the left chest wall, in the range of the seventh to ninth rib. According to the medical history, the patient did not have any prior trauma and malignancy. A well-defined tumor of the left chest wall with calcifications, which grew to the seventh and eighth intercostal space, was present on computed tomography (CT) and magnetic resonance (MR) scans. The patient underwent resection of the tumor with the chest wall and reconstruction with polypropylene mesh. Histologically, it was a venous hemangioma, one of very rare tumors of the chest wall.

ABSTRACT

INTRODUCTION: Superior vena cava syndrome (SVCS) is obstruction of blood flow through the SVC. It is a medical emergency and most often manifests in patients with a malignant disease process within the thorax. A patient with SVCS requires immediate diagnostic evaluation and therapy. PRESENTATION OF CASE: A 33-years-old woman presented with complaints of dyspnoea and chest pain. Computer tomography revealed a large mass in the anterior mediastinum. This mass compressed surrounding structures. Stenting was indicated for early symptoms of SVCS. The diagnosis of Hodgkin's lymphoma (HL) was confirmed with biopsy. The patient's stage II HL has been subsequently treated with six cycles of chemotherapy with doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD), followed by radiotherapy. Presently she is doing well. DISCUSSION: Although lymphomas are a common cause of SVCS but almost always SVCS is caused by non-Hodgkin's lymphoma (NHL). HL despite its common presentation with mediastinal lymphadenopathy rarely causes SVCS. CONCLUSION: Lymphomas are a common cause of SVCS in young age. HL may present as SVCS. Pathological confirmation of diagnosis should be done before initiating therapy while dealing with a case of SVCS. SVC stenting is effective and has few complications in patients with SVCS.
