Post-Traumatic Left Subclavian Artery Pseudoaneurysm Secondary to Clavicular Fracture: A Case Report and Literature Review.

Subclavian artery pseudoaneurysms are rare but potentially life-threatening vascular injuries frequently associated with trauma such as clavicle fractures. In this paper we describe the case of a 49-year-old male who developed a post-traumatic pseudoaneurysm of the subclavian artery after a bicycle accident. The diagnosis was delayed due to non-specific symptoms and an initially missed aneurysm on computed tomography imaging.

Natural Deep Eutectic Solvents Combined with Supercritical Carbon Dioxide for the Extraction of Curcuminoids from Turmeric.

Background: Curcuminoids, the bioactive compounds found in turmeric, exhibit potent antioxidant, anti-inflammatory, and neuroprotective properties. This study aims to enhance the extraction of curcuminoids from turmeric using environmentally friendly solvents supercritical CO (scCO) combined with natural deep eutectic solvents (NADESs) in one process, and to evaluate the resulting biological activity.

Methods: A Box-Behnken statistical design was applied to optimize scCO extraction conditions-pressure, CO volume, and temperature-to maximize curcuminoid yield.

Surgical Treatment and Targeted Therapy for a Large Metastatic Malignant Peripheral Nerve Sheath Tumor: A Case Report and Literature Review.

Neurofibromatosis type 1 (NF1) significantly increases the risk of malignant peripheral nerve sheath tumors (MPNST), a rare and aggressive malignancy for which treatment is clinically challenging. This paper presents the case of a 24-year-old male with an NF1 who developed MPNST with lung metastases. Due to the limited effectiveness of systemic therapy in the treatment of MPNST, the patient underwent radical surgical resection and radiotherapy.

Parallel Wire Approach for Recanalisation of Chronic Total Coronary Occlusions in a Large Contemporary Multi-Center Registry.

Background: The parallel wire technique (PW) is a classic part of the antegrade strategy to open chronic total coronary occlusions (CTO).

Aims: With modern wires and dual-lumen catheters (DLC) the approach has evolved, but this progress had not been evaluated in a contemporary registry of CTO interventions.

Method: This analysis is based on 26,589 CTO procedures performed by 36 operators with > 50 procedures annually between 2015 and 2022.

The Influence of the Parameters of the Skew Rolling Process for Bimetallic Elements on the Mechanical Properties and Structure of Materials.

This paper presents selected results of theoretical and experimental research into the manufacture of axisymmetric bimetallic components using three-tool skew rolling technology. In the tests, it was assumed that the outer layer would be a material intended for heat treatment. However, low-carbon steel was used for the core.

Analysis of Primary Graft Dysfunction (PGD) Risk Factors in Lung Transplantation (LuTx) Patients.

Background: Primary graft dysfunction (PGD) is a form of acute lung injury (ALI) that occurs within 72 h after lung transplantation (LuTx) and is the most common early complication of the procedure. PGD is diagnosed and graded based on the ratio of the partial pressure of arterial oxygen to the fraction of inspired oxygen and chest X-ray results. PGD grade 3 increases recipient mortality and the chance of chronic lung allograft dysfunction (CLAD).

Consultations for Poland Syndrome: The Essentials for a Thoracic Surgeon.

Poland syndrome (PS) is a rare congenital musculoskeletal entity occurring in approximately 1 in 30,000 newborns that manifests with variable symbrachydactyly, ipsilateral costochondral deformities, an absence of pectoral muscles, and breast underdevelopment. These have potential impacts on social, somatic, and psychological functionality, often leading affected individuals to seek expert opinions on corrective surgery. Due to phenotypic variability, strict management guidelines are lacking, with treatment decisions often based on the specialist's personal experience rather than published evidence.

A Rare Case of Primary Pulmonary Diffuse Large B-Cell Lymphoma Transformed from Marginal Zone Mucosa-Associated Lymphoid Tissue Lymphoma.

Primary pulmonary lymphoma is a rare neoplasm characterized by the proliferation of lymphoid tissue affecting the lungs. The most common subtype is marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT). Rarely, a MALT lymphoma transforms into a diffuse large B-cell lymphoma (DLBCL).

Gait Analysis in Patients with Symptomatic Pes Planovalgus Following Subtalar Arthroereisis with the Talus Screw.

Background: Pes planovalgus is one of the most common pediatric skeletal deformities. There have been no studies to analyze in detail the spatiotemporal variables of gait following arthroereisis.

Purpose Of The Study: The purpose of our study was to assess gait parameters in patients with symptomatic flexible flatfoot following treatment with the talus screw.

Evaluation of the effects of postoperative pleural empyema on survival rates of patients after pneumonectomy due to non-small cell lung cancer.

Introduction: Postpneumonectomy empyema (PPE) is a severe and often fatal complication of pneumonectomy, but some benefits of PPE were reported in patients who underwent either lobe or an entire lung resection due to lung cancer.

Aim: To compare the survival outcomes of patients with non-small-cell lung carcinoma (NSCLC), who developed PPE after pneumonectomy with uneventful recoveries available in our center's database.

Material And Methods: Outcomes of 928 pneumonectomies performed due to NSCLC between 1995 and 2009 were evaluated.

Exposing hypersensitivity in quantum chaotic dynamics.

We study hypersensitivity to initial-state perturbation in the unitary dynamics of a multiqubit system. We use the quantum state metric, introduced by Girolami and Anza [Phys. Rev.

A comprehensive calibration of integrated magnetron sputtering and plasma enhanced chemical vapor deposition for rare-earth doped thin films.

Unlabelled: A new integrated deposition system taking advantage of magnetron sputtering and electron cyclotron-plasma enhanced chemical vapour deposition (IMS ECR-PECVD) is presented that mitigates the drawbacks of each fabrication system. This tailor-made system provides users with highly homogeneous and pure thin films with less undesired hydrogen and well-controlled rare-earth concentration compared to existing methods of rare-earth doping, such as metalorganic powders, sputtering, and ion implantation. We established the first comprehensive report on the deposition parameters of argon flow and sputtering power to achieve desired rare-earth concentrations in a wide composition range of terbium (Tb) doped-silicon oxide (Tb:SiO) matrices including silicon-rich ( < 2), oxygen-rich ( > 2), and stoichiometric silicon oxide ( = 2).

Hydrogen Sulfide Adsorption from Natural Gas Using Silver-Modified 13X Molecular Sieve.

The removal of hydrogen sulfide from natural gas and other gases such as biogas, refinery gases, and coal gas is required because it is toxic and corrosive, even in traces. Zeolites are widely used in the removal of HS from the abovementioned gases. In this work, we prepared an Ag-exchanged 13X molecular sieve by using different concentrations of AgNO to increase its adsorption properties.

An MR spectroscopy study of temporal areas excluding primary auditory cortex and frontal regions in subjective bilateral and unilateral tinnitus.

Previous studies indicate changes in neurotransmission along the auditory pathway in subjective tinnitus. Most authors, however, investigated brain regions including the primary auditory cortex, whose physiology can be affected by concurrent hearing deficits. In the present MR spectroscopy study we assumed increased levels of glutamate and glutamine (Glx), and other Central Nervous System metabolites in the temporal lobe outside the primary auditory cortex, in a region involved in conscious auditory perception and memory.

Examination of resistance of various methods of pulmonary vessel occlusion to hydrostatic pressure.

Objective: The aim of this study was to compare pressure resistance of the most common methods of vessel occlusion during thoracic surgical procedures: ligations, clips, and vascular endostaplers.

Methods: Pulmonary vessels were obtained during routine thoracic surgeries. A ball-tipped cannula was inserted through an opening in the side wall and secured with a linen ligature from slipping out.

Comparison of peripheral blood saturation with brain oxygenation in patients undergoing thoracic surgery.

Introduction: Near-infrared spectroscopy (NIRS) is a non-invasive method of regional tissue oxygenation measurement. Intraoperative use of NIRS to monitor brain oxygenation (BO) during surgery might be beneficial to identify cerebral desaturations.

Aim: To compare peripheral blood saturation (SpO) with BO measurements and evaluate the utility of BO in thoracic surgery.

Classification of Daily Body Weight Gains in Beef Calves Using Decision Trees, Artificial Neural Networks, and Logistic Regression.

The aim of the present study was to compare the predictive performance of decision trees, artificial neural networks, and logistic regression used for the classification of daily body weight gains in beef calves. A total of 680 pure-breed Simmental and 373 Limousin cows from the largest farm in the West Pomeranian Province, whose calves were fattened between 2014 and 2016, were included in the study. Pre-weaning daily body weight gains were divided into two categories: A-equal to or lower than the weighted mean for each breed and sex and B-higher than the mean.
