Role of , , and in determining the prognosis of patients with lung adenocarcinoma.

Background: Non-small cell lung cancer (NSCLC) accounts for about 85% of lung cancers, and is the leading cause of tumor-related death. Lung adenocarcinoma (LUAD) is the most prevalent subtype of NSCLC. Although significant progress of LUAD treatment has been made under multimodal strategies, the prognosis of advanced LUAD is still poor due to recurrence and metastasis.

[Non-Intubated Video-assisted Thoracoscopic Surgery (niVATS)].

Non-intubated minimally invasive lung surgery garnered renewed interest during the past decade and many centers across the country successfully implemented the technique for minor procedures like pleurodesis or wedge resection. Anatomical lung resection under spontaneous breathing still is considered as challenging, and as existing data to support it is conflicting and confusing, the approach remains limited to few dedicated outfits. We seek to present the historical perspective, critically report potential advantages and limitations of the technique and hand out a guideline that might prove to be helpful in building up a dedicated program.

Long-Term Outcome of Chest Wall and Diaphragm Repair with Biological Materials.

Introduction:  Chest wall and/or diaphragm reconstruction aims to preserve, restore, or improve respiratory function; conserve anatomical cavities; and upkeep postural and upper extremity support. This can be achieved by utilizing a wide range of different grafts made of synthetic, biological, autologous, or bioartificial materials. We aim to review our experience with decellularized bovine pericardium as graft in the past decade.

Management and outcome of obstructive airway complications after lung transplantation - a 12-year retrospective cohort study.

Comparison of uniportal robotic-assisted thoracic surgery pulmonary anatomic resections with multiport robotic-assisted thoracic surgery: a multicenter study of the European experience.

Background: Robotic-assisted thoracic surgery (RATS) has seen increasing interest in the last few years, with most procedures primarily being performed in the conventional multiport manner. Our team has developed a new approach that has the potential to convert surgeons from uniportal video-assisted thoracic surgery (VATS) or open surgery to robotic-assisted surgery, uniportal-RATS (U-RATS). We aimed to evaluate the outcomes of one single incision, uniportal robotic-assisted thoracic surgery (U-RATS) against standard multiport RATS (M-RATS) with regards to safety, feasibility, surgical technique, immediate oncological result, postoperative recovery, and 30-day follow-up morbidity and mortality.

Surgical management of large tracheoesophageal fistula in infants after button battery ingestion.

Objectives: In recent years, an increase in severe and even fatal outcomes related to oesophageal or airway button battery (BB) ingestion by infants and small children has been reported. Extensive tissue necrosis caused by lodged BB can lead to major complications, including tracheoesophageal fistula (TEF). In these instances, best treatment remains controversial.

Uniportal video-assisted thoracic surgery basal segmentectomy: a single-center retrospective cohort study.

Background: Uniportal video-assisted thoracic surgery (VATS) basal segmentectomy is technically challenging and requires a deep understanding of the segmental anatomy of the lung. This report describes the uniportal VATS segmentectomy of basal segments using a single-direction approach.

Methods: A total of 49 patients who underwent uniportal VATS basal segmentectomy between April 2019 and April 2021 were included in this retrospective study.

Surgical Lung Biopsy for Interstitial Lung Disease: A Two Center Propensity Score Matching Analysis.

Background: Surgical lung biopsy (SLB) is recommended for patients with nonclassified interstitial lung disease (nILD) if high resolution computed tomography and/or transbronchial lung biopsy did not achieve a definitive diagnosis. Current literature suggests better patient tolerability and less postoperative complications if surgery is performed under spontaneous ventilation.

Objectives: We conducted a propensity score matching (PSM) analysis of our nILD patients undergoing SLB under spontaneous ventilation or general anesthesia to investigate postprocedural AE-ILD, 30-/90-day mortality and perioperative variables in two academic high-volume centers (Hannover, Heidelberg).

The strategy of non-intubated spontaneous ventilation anesthesia for upper tracheal surgery: a retrospective case series study.

Background: Upper tracheal surgery is used to treat patients who with tracheal tumors or tracheal stenosis. The non-intubated spontaneous ventilation anesthesia (NSVA) may have advantages over endotracheal intubation and surgical cross-field intubation in upper tracheal surgery. This study aimed to illustrate and assess the feasibility of NSVA strategy for upper tracheal surgery.

Role of Pre-Operative Brain Imaging in Patients with NSCLC Stage I: A Retrospective, Multicenter Analysis.

Lung cancer is the worldwide leading oncological cause of death in both genders combined and accounts for around 40-50% of brain metastases in general. In early-stage lung cancer, the incidence of brain metastases is around 3%. Since the early detection of asymptomatic cerebral metastases is of prognostic value, the aim of this study was to analyze the incidence of brain metastases in early-stage lung cancer and identify possible risk factors.

[Case Series Report: Management of Anesthesia in Children Undergoing Complex Surgery of Tracheoesophageal Fistula after Ingestion of Button Batteries].

Button battery ingestions in children increased in recent years and may lead to life-threatening complications, especially if the battery is impacted in the esophagus. The pH close to the negative pole of the battery can rise in a very alkalotic range (pH > 10) leading to severe tissue damage. Therefore, in this case series report, the clinical courses of four children with button battery ingestion leading to tracheoesophageal fistulas are presented.

Surgical treatment of non-cystic fibrosis bronchiectasis in Central Europe.

Background: Bronchiectasis is a mostly irreversible bronchial dilatation induced by the destruction of elastic and muscular fibers of the bronchial wall. Surgical treatment is usually reserved for focal disease, and whenever complications, like hemoptysis or secondary aspergilloma, arise. In this study, we report our experience and outcomes in surgical bronchiectasis management between 2016 and 2020.

α1-Antitrypsin attenuates acute rejection of orthotopic murine lung allografts.

Background: α1-Antitrypsin (AAT) is an acute phase glycoprotein, a multifunctional protein with proteinase inhibitory, anti-inflammatory and cytoprotective properties. Both preclinical and clinical experiences show that the therapy with plasma purified AAT is beneficial for a broad spectrum of inflammatory conditions. The potential effects of AAT therapy have recently been highlighted in lung transplantation (LuTx) as well.

Analysis of pH and electrolytes in blood and ruminal fluid, including kidney function tests, in sheep undergoing long-term surgical procedures.

Background: The physiology of sheep as small ruminants is remarkably different from monogastric animals especially regarding the forestomach system. Using sheep for surgical procedures during scientific research thereby presents an exceptional setting for the anaesthetist. Long-term anaesthesia generally demands deprivation of food to reduce the risk of bloat in sheep.

Monitoring excimer laser-guided cardiac lead extractions by uniportal video-assisted thoracoscopy: A single center experience.

Background: Though laser guided extractions of cardiac implantable electronic devices leads have become a routine procedure, the severe complications are associated with a high mortality. Here, we report our single center experience using uniportal video-assisted thoracoscopy for laser lead extraction and compare it to stand-alone laser lead extraction.

Methods: The intraoperative data and postoperative clinical outcomes of patients undergoing laser lead extraction with concomitant thoracoscopy ( = 28) or without ( = 43) in our institution were analyzed retrospectively.

Impact of sarcopenia in advanced and metastatic soft tissue sarcoma.

Introduction: Advanced or metastatic soft tissue sarcoma (a/mSTS) is associated with a dismal prognosis. Patient counseling on treatment aggressiveness is pivotal to avoid over- or undertreatment. Recently, evaluation of body composition markers like the skeletal muscle index (SMI) became focus of interest in a variety of cancers.

Rhinovirus-induced Human Lung Tissue Responses Mimic Chronic Obstructive Pulmonary Disease and Asthma Gene Signatures.

Human rhinovirus (RV) is a major risk factor for chronic obstructive pulmonary disease (COPD) and asthma exacerbations. The exploration of RV pathogenesis has been hampered by a lack of disease-relevant model systems. We performed a detailed characterization of host responses to RV infection in human lung tissue and investigated whether these responses are disease relevant for patients with COPD and asthma.

[Multidisciplinary Management of Non-cystic-fibrosis Bronchiectasis - State of the Art].

Bronchiectasis is a mostly irreversible bronchial dilatation induced by a destruction of elastic and muscular fibers of the bronchial wall. Radiological criteria of bronchiectasis are met, when the inner diameter of the bronchial wall surpasses the outer diameter of the accompanying pulmonary artery. Its incidence increases with age, even though it often lacks true clinical signs of disease.

Developing a minimally-invasive anaesthesiological approach to non-intubated uniportal video-assisted thoracoscopic surgery in minor and major thoracic surgery.

Background: Non-intubated uniportal video-assisted thoracoscopic surgery (niVATS) is a novel approach to major and minor lung resection. It benefits from a holistic anesthesiological concept with adequate pain relief and sedation in a minimal-invasive setup allowing thoracic procedures under spontaneous breathing. At present no anesthesiological gold standard for niVATS exists.

To better diagnose LC and to predict drug treatment responses we evaluated 228 articles encompassing 16,697 patients and 12,582 healthy controls. Based on the criteria of ≥3 independent studies and a sensitivity and specificity of >0.

Multiparametric MRI for organ quality assessment in a porcine Ex-Vivo lung perfusion system.

Introduction: Ex-vivo lung perfusion (EVLP) is an emerging technique promising an expansion of the donor pool and improvements in the outcome after lung transplantation. Reliable biomarkers for local assessment of organ function in the EVLP system are intensely sought after. This study aims to evaluate the feasibility of multiparametric functional magnetic resonance imaging (fMRI) in an EVLP system in a porcine aspiration model.

Surgical teaching at the Medical School Otto-von-Guericke University of Magdeburg - basic conceptual description.

Teaching in surgery, one of the classical big clinical and main disciplines beside internal medicine, needs to be also associated with great attention in regard to a valuable final result at the end of the study of human medicine. In particular, surgery is not only the subject to a large number of lectures it also represents one third (four months) of the compulsory internship (practical year - in German, "Praktisches Jahr") at the end of the study of medicine. Therefore, medical teaching of students should be always part of serious and steady attempts to optimize course und contents as a component of guiding activities focussing onto the substantial improvement of the study of medicine.
