Biological effects of COVID-19 on lung cancer: Can we drive our decisions.

COVID-19 infection caused by SARS-CoV-2 is considered catastrophic because it affects multiple organs, particularly those of the respiratory tract. Although the consequences of this infection are not fully clear, it causes damage to the lungs, the cardiovascular and nervous systems, and other organs, subsequently inducing organ failure. In particular, the effects of SARS-CoV-2-induced inflammation on cancer cells and the tumor microenvironment need to be investigated.

Comparative Analysis of Free-Circulating and Vesicle-Associated Plasma microRNAs of Healthy Controls and Early-Stage Lung Cancer Patients.

In recent years, circulating extracellular miRNAs have emerged as a useful tool for the molecular characterization and study of tumors' biological functions. However, the high heterogeneity in sample processing, isolation of circulating fraction, RNA extraction, and sequencing hamper the reproducibility and the introduction of these biomarkers in clinical practice. In this paper, we compare the content and the performance of miRNA sequencing in plasma-derived samples processed with different isolation protocols.

Extra Virgin Olive Oil (EVOO), a Mediterranean Diet Component, in the Management of Muscle Mass and Function Preservation.

Aging results in a progressive decline in skeletal muscle mass, strength and function, a condition known as sarcopenia. This pathological condition is due to multifactorial processes including physical inactivity, inflammation, oxidative stress, hormonal changes, and nutritional intake. Physical therapy remains the standard approach to treat sarcopenia, although some interventions based on dietary supplementation are in clinical development.

Phenotypic, functional, and metabolic heterogeneity of immune cells infiltrating non-small cell lung cancer.

Lung cancer is the leading cancer in the world, accounting for 1.2 million of new cases annually, being responsible for 17.8% of all cancer deaths.

Management of Preschool Wheezing: Guideline from the Emilia-Romagna Asthma (ERA) Study Group.

Preschool wheezing should be considered an umbrella term for distinctive diseases with different observable and measurable phenotypes. Despite many efforts, there is a large gap in knowledge regarding management of preschool wheezing. In order to fill this lack of knowledge, the aim of these guidelines was to define management of wheezing disorders in preschool children (aged up to 5 years).

Second Surgery for Recurrent Malignant Pleural Mesothelioma after Multimodality Treatment: A Systematic Review.

Malignant pleural mesothelioma (MPM) is an aggressive asbestos-related tumour with poor prognosis. To date, a multimodality treatment, including chemotherapy and surgery, with or without radiotherapy, is the gold standard therapy for selected patients with epithelioid and early-stage MPM. In this setting, the goal of surgery is to achieve the macroscopic complete resection, obtained by either extrapleural pneumonectomy or pleurectomy/decortication.

The role of Ivor Lewis esophagectomy in the treatment of achalasia with megaesophagus: A case report.

Introduction: Achalasia with megaesophagus is a pathology characterized by widespread and irregular dilation of the esophageal lumen. In most cases, this dilation is caused by contraction and subsequent failed relaxation of the lower esophageal sphincter (LES). It may be associated with a partial or complete slowing of the esophageal peristalsis.

Cancer Stem Cells (CSCs), Circulating Tumor Cells (CTCs) and Their Interplay with Cancer Associated Fibroblasts (CAFs): A New World of Targets and Treatments.

The importance of defining new molecules to fight cancer is of significant interest to the scientific community. In particular, it has been shown that cancer stem cells (CSCs) are a small subpopulation of cells within tumors with capabilities of self-renewal, differentiation, and tumorigenicity; on the other side, circulating tumor cells (CTCs) seem to split away from the primary tumor and appear in the circulatory system as singular units or clusters. It is becoming more and more important to discover new biomarkers related to these populations of cells in combination to define the network among them and the tumor microenvironment.

The Influence of Cancer Stem Cells on the Risk of Relapse in Adenocarcinoma and Squamous Cell Carcinoma of the Lung: A Prospective Cohort Study.

Purpose: Lung cancer relapse may be associated with the presence of a small population of cancer stem cells (CSCs) with unlimited proliferative potential. Our study assessed the relationship between CSCs and the relapse rate in patients harboring adenocarcinoma (ADL) and squamous cell carcinoma of the lung (SCCL).

Experimental Design: This is an observational prospective cohort study (NCT04634630) assessing the influence of CSC frequency on relapse rate after major lung resection in 35 patients harboring early (I-II) (n = 21) and locally advanced (IIIA) (n = 14) ADL and SCCL.

The importance of diaphragmatic surgery, chemical pleurodesis and postoperative hormonal therapy in preventing recurrence in catamenial pneumothorax: a retrospective cohort study.

Background: Catamenial pneumothorax (CP) is defined as a recurrent, spontaneous pneumothorax occurring within a day before or 72 h after the onset of menstruation. Most first episodes go undiagnosed and treated as primary spontaneous pneumothorax, and only after recurrence is the clinical suspicion of CP raised. No gold-standard management approach exists, especially in terms of managing diaphragmatic involvement.

Surgical results of non-small cell lung cancer involving the heart and great vessels.

Background: The surgical treatment of advanced non-small-cell-lung-cancer (NSCLC) invading mediastinal organs and great vessels is still controversial. The aim of this multicentre study is to analyse oncological outcomes, surgical outcomes and prognostic factors of patients with NSCLC involving heart and great vessels.

Methods: 362 patients treated surgically for locally advanced T4-NCSLC between 1990 and 2020 were retrospectively reviewed.

Totally thoracoscopic versus standard VATS lobectomies: perioperative differences.

Background: Minimally invasive surgery is considered the gold standard approach for early stage lung cancer. Techniques range from a standard three-port approach to uniportal lobectomies, with no technique emerging as superior thus far. We retrospectively compared the pain outcomes of a standard approach using a utility incision with a totally thoracoscopic technique.

Dissecting Tumor Growth: The Role of Cancer Stem Cells in Drug Resistance and Recurrence.

Emerging evidence suggests that a small subpopulation of cancer stem cells (CSCs) is responsible for initiation, progression, and metastasis cascade in tumors. CSCs share characteristics with normal stem cells, i.e.

A radiomics model combined with XGBoost may improve the accuracy of distinguishing between mediastinal cysts and tumors: a multicenter validation analysis.

Background: Mediastinal cysts (MCs) can be misdiagnosed as mediastinal tumors (MTs) such as thymomas on the basis of radiological examinations, including computerized tomography (CT) and magnetic resonance imaging (MRI). Our study aimed to determine the utility of a radiomics model combined with eXtreme Gradient Boosting (XGBoost) for diagnosing anterior mediastinal masses.

Methods: Patients with anterior mediastinal lesions admitted to Shanghai Pulmonary Hospital between October 2014 and January 2018 were enrolled in the study.

Primary and secondary cardiac tumors: clinical presentation, diagnosis, surgical treatment, and results.

Cardiac tumours are some of the rarest primary tumours, while cardiac metastasis are more common yet still relatively rare. Seventy five percent of primary cardiac tumours are benign tumours. Cardiac tumours present with a range of obstructive, embolic, arrhythmic or systemic symptoms, and in many cases may present asymptomatically.

A large and late mediastinal metastasis from a uterine smooth muscle tumour of uncertain malignant potential: A case report.

Introduction: Smooth muscle tumours of uncertain malignant potential (STUMP) are mesenchymal uterine tumours with a malignant potential found somewhere between that of benign leiomyomas and leiomyosarcomas. Only three cases of STUMP pulmonary metastasis exist in the literature.

Case Presentation: We report the case of a 63 year-old female patient presenting with dysphonia secondary to recurrent laryngeal nerve paralysis due to an enormous mediastinal STUMP metastasis, 14 years after having undergone a total hysterectomy with bilateral salpingo-oophorectomy.

Long term results of surgery for NSCLC and aortic invasion. A multicenter retrospective cohort study.

Background: Aortic invasion from non-small cell lung cancers (NSCLC) is a relative contraindication to surgery for oncological and technical reasons. Only a few studies have been published showing good results. Our aim was to evaluate short and long-term results of surgery for T4 NSCLC with aortic resection.

A Review on P300 in Obsessive-Compulsive Disorder.

Neuropsychological studies indicate the presence of cognitive changes in patients with obsessive-compulsive disorder (OCD). Indeed, OCD may be included among the dysfunctions of the frontal lobes and their connections with the limbic system, associative cortex, and basal ganglia. P300 is a positive component of the human event-related potential (ERP); it is associated with processes of encoding, identification, and categorization constituting, as a whole, the superior cortical function of information processing.

Management of Children with Acute Asthma Attack: A RAND/UCLA Appropriateness Approach.

Bronchial asthma is the most frequent chronic disease in children and affects up to 20% of the pediatric population, depending on the geographical area. Asthma symptoms vary over time and in intensity, and acute asthma attack can resolve spontaneously or in response to therapy. The aim of this project was to define the care pathway for pediatric patients who come to the primary care pediatrician or Emergency Room with acute asthmatic access.

Deepening the Knowledge of Rearrangements in Non-Small Cell Lung Cancer: Diagnosis, Treatment, Resistance and Concomitant Alterations.

rearrangements are reported in about 1-2% of non-squamous non-small-cell lung cancer (NSCLC). After efficacy of crizotinib was demonstrated, identification of translocations in advanced disease became fundamental to give patients the chance of specific and effective treatment. Different methods are available for detection of rearrangements, and probably the real prevalence of rearrangements is higher than that reported in literature, as our capacity to detect gene rearrangements is improving.

Molecular Mechanisms and Cellular Contribution from Lung Fibrosis to Lung Cancer Development.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fibrosing interstitial lung disease (ILD) of unknown aetiology, with a median survival of 2-4 years from the time of diagnosis. Although IPF has unknown aetiology by definition, there have been identified several risks factors increasing the probability of the onset and progression of the disease in IPF patients such as cigarette smoking and environmental risk factors associated with domestic and occupational exposure. Among them, cigarette smoking together with concomitant emphysema might predispose IPF patients to lung cancer (LC), mostly to non-small cell lung cancer (NSCLC), increasing the risk of lung cancer development.

Impact of COVID-19 pandemic on the neuropsychiatric status of Wilson's disease.

We have read with interest the Letter to the Editor by Drs. Zhuang and Zhong, who presented the clinical data of 68 patients with Wilson's disease (WD) who were admitted to the hospital before and during the coronavirus disease 2019 (COVID-19) pandemic, and appreciated their findings on hepatic and some extrahepatic manifestations. Nevertheless, given the strong impact of the pandemic on patients with neurological and psychiatric disorders, we would have expected a worsening of the psychiatric and/or neurological impairments in these patients.
