Abstract
OBJECTIVE The aim was to reveal the morphological features of the lungs in post-COVID-19 syndrome. PATIENTS AND METHODS Materials and methods: The material of the study was autopsy material - fragments of the lung tissue from 96 deceased (59 men and 37 women). During the lifetime, all patients had in anamnesis COVID-19 of varying severity, and after the treatment of this infection, they had various manifestations of respiratory failure until death. The average duration of the post-COVID-19 period was 148.6±9.5 days. Based on the severity of COVID-19 in anamnesis, all cases were divided into three groups. Group 1 included 39 cases with mild COVID-19 in anamnesis. Group 2 included 24 cases with moderate severity of COVID-19 in an-amnesis. Group 3 included 33 cases with severe COVID-19 in anamnesis. Histological, histochemical, morphometric and statistical research methods were used. RESULTS Results: Morphological features of the lungs in post-COVID-19 syndrome were the presence of pneumosclerosis; focal-diffuse immune cells infiltration; emphysematous and atelectatic changes; degenerative-desquamatic changes in the alveolar epithelium; metaplastic changes of connective tissue; dystrophic calcification; dystrophic, metaplastic and dysplastic changes in the epithelial layer of bronchial tree; hemodynamic disorders. Pneumosclerosis, focal-diffuse immune cells infiltration, alterative changes in the alveolar epithelium, emphysematous and atelectatic changes, hemodynamic disorders increased with an increase the severity of COVID-19. Metaplastic changes of connective tissue, dystrophic calcification, dystrophic, metaplastic and dysplastic changes in epithelial layer of bronchial tree did not depend on the severity of the infection. CONCLUSION Conclusions: The changes identified by the authors help to explain pulmonary manifestations of post-COVID-19 syndrome. They should be the basis for the oncological alertness formation among doctors, the development of rehabilitation and treatment measures for such category of patients.

Abstract
Objective We systematically review the molecular mechanism of the interaction between lung cancer (LC) and tuberculosis (TB), and put forward the existing problems in order to provide suggestions for early intervention and future research direction. Background TB and LC are two global public health problems affecting human health. LC is the main cause of cancer-related death worldwide and TB is one of the leading causes of death among infectious diseases, especially in resource-poor areas. Previous studies have suggested that a history of TB may be associated with an increased risk of LC. With the improvement of LC treatment, the occurrence of pulmonary tuberculosis in the course of LC treatment is also frequently reported recently. Methods The molecular immunological mechanisms of interaction between LC and TB, and related epidemiological literature are reviewed. The research progress and problems to be solved are summarized. Conclusions Chronic inflammation, immune abnormalities, scar formation, gene mutations and drug effects caused by TB may be associated with the occurrence of LC induced by abnormalities in various molecular pathways. LC and decreased immunity during treatment may also increase the risk of latent TB activation or new TB infection through immune pathways. Data on dual burden areas of TB and LC are still lacking, and more clinical studies are needed to elucidate the association.

Fourier Transform Infrared Polarization Contrast Imaging Recognizes Proteins Degradation in Lungs upon Metastasis from Breast Cancer. Cancers (Basel) 2021; 13:cancers13020162. [PMID: 33418894 PMCID: PMC7825053 DOI: 10.3390/cancers13020162] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 12/18/2020] [Accepted: 01/01/2021] [Indexed: 01/19/2023] Open
Abstract
Simple Summary Several lung extracellular matrix (ECM) proteins are involved in the formation of a metastatic niche in pulmonary metastasis and they accompany the cancer progression. Its gradual remodeling does not induce compositional changes of its components, but it is related to the re-distribution of individual proteins, their cross-linking and spatial arrangement within the tissue. The combination of FTIR and FTIR polarization contrast (PCI) imaging, as rapid, non-destructive, and label-free techniques, allows for the determination of protein alternations occurring in lungs that are affected by breast cancer metastasis. Both have the potential to characterize biochemical changes of the metastatic target, can determine phenotypes of tissue structures, and deliver a novel spectroscopic marker panel for the recognition of metastasis environment. Abstract The current understanding of mechanisms underlying the formation of metastatic tumors has required multi-parametric methods. The tissue micro-environment in secondary organs is not easily evaluated due to complex interpretation with existing tools. Here, we demonstrate the detection of structural modifications in proteins using emerging Fourier Transform Infrared (FTIR) imaging combined with light polarization. We investigated lungs affected by breast cancer metastasis in the orthotopic murine model from the pre-metastatic phase, through early micro-metastasis, up to an advanced phase, in which solid tumors are developed in lung parenchyma. The two IR-light polarization techniques revealed, for the first time, the orientational ordering of proteins upon the progression of pulmonary metastasis of breast cancer. Their distribution was complemented by detailed histological examination. Polarized contrast imaging recognised tissue structures of lungs and showed deformations in protein scaffolds induced by inflammatory infiltration, fibrosis, and tumor growth. This effect was recognised by not only changes in absorbance of the spectral bands but also by the band shifts and the appearance of new signals. Therefore, we proposed this approach as a useful tool for evaluation of progressive and irreversible molecular changes that occur sequentially in the metastatic process.
