Heterogeneous photocatalysis is a potential technique for the removal of organic pollutants from the wastewater. In this article, zinc oxide (ZnO) and samarium oxide (SmO) nanoparticles and ZnO-SmO nanocomposite (ZS) were synthesized by the co-precipitation method.

Influence of natural additives on the properties of a milk-based compostable bioplastic.

The ongoing revolution in the plastic sector is the use of renewable and compostable materials obtained from biomass. However, their mechanical strength and thermal stability are generally not sufficient for practical applications. This study investigates the influence of natural additives on the physical-mechanical properties of a new biobased compostable bioplastic, SP-Milk®, produced from milk scraps.

Functionalized orthopaedic implant as pH electrochemical sensing tool for smart diagnosis of hardware infection.

In the orthopaedic surgery field, the use of medical implants to treat a patient's bone fracture is nowadays a common practice, nevertheless, it is associated with possible cases of infection. The consequent hardware infection can lead to implant failure and systemic infections, with prolonged hospitalization, time-consuming rehabilitation treatments, and extended antibiotic therapy. Hardware infections are strictly related to bacterial adhesion to the implant, leading to infection occurrence and consequent pH decreasing from physiological level to acid pH.

Challenging repair of the left subclavian vein in a pediatric patient.

This is a case involving a 3-year-old child who presented with an iatrogenic left subclavian/innominate vein lesion, leading to severe bleeding and intravascular catheter rupture during its removal. We successfully performed a very challenging and minimally invasive repair of the vein, along with the removal of the catheter entrapped in the innominate vein.

Among the methods for water purification from organic pollutants, photodegradation is certainly a valid technique to decrease such contaminants.

Major vascular reconstructions in thoracic oncological surgery.

The replacement of the superior vena cava and thoracic outlet vessels for thoracic malignancies often becomes necessary for radical oncological surgery. The pulmonary artery can be directly infiltrated by the tumor or affected by metastatic hilar lymph nodes. In some cases, it must be resected and reconstructed to achieve oncological radicality and/or avoid pneumonectomy.

Copper-Enhanced CO Electroreduction in SOECs.

The development of a Co-free and Ni-free electrocatalyst for carbon dioxide electrolysis would be a turning point for the large-scale commercialization of solid-oxide electrolysis cells (CO-SOECs). Indeed, the demand for cobalt and nickel is expected to become critical by 2050 due to automotive electrification. Currently, the reference materials for CO-SOEC electrodes are perovskite oxides containing Mn or Co (anodes) and Ni-YSZ cermets (cathodes).

Surgery-related outcomes from a close-knit surgeons' team in thoracic oncology.

Reducing morbidity, length of hospital stay, and readmission rate are of paramount importance to improve patients' care. In the present paper, we aim to describe our experience in managing major oncologic thoracic surgery in clinical practice. This is a retrospective experience over the last 7 years.

New perspectives in prosthetic reconstruction in chest wall resection.

The extension of chest wall resection for the treatment of primary and secondary tumours is still widely debated. The reconstructive strategy after extensive surgery is challenging as well as chest wall demolition itself. Reconstructive surgery aims to avoid respiratory failure and to guarantee intra-thoracic organs protection.

Characterization of Conductive Carbon Nanotubes/Polymer Composites for Stretchable Sensors and Transducers.

The increasing interest in stretchable conductive composite materials, that can be versatile and suitable for wide-ranging application, has sparked a growing demand for studies of scalable fabrication techniques and specifically tailored geometries. Thanks to the combination of the conductivity and robustness of carbon nanotube (CNT) materials with the viscoelastic properties of polymer films, in particular their stretchability, "surface composites" made of a CNT on polymeric films are a promising way to obtain a low-cost, conductive, elastic, moldable, and patternable material. The use of polymers selected for specific applications, however, requires targeted studies to deeply understand the interface interactions between a CNT and the surface of such polymer films, and in particular the stability and durability of a CNT grafting onto the polymer itself.

Poly(ethylene glycol) Diacrylate Hydrogel with Silver Nanoclusters for Water Pb(II) Ions Filtering.

Poly(ethylene glycol) diacrylate (PEGDA) hydrogels modified with luminescent silver nanoclusters (AgNCs) are synthesized by a photo-crosslinking process. The hybrid material thus obtained is employed to filter Pb(II) polluted water. Under the best conditions, the nanocomposite is able to remove up to 80-90% of lead contaminant, depending on the filter composition.

Long term outcome of complex surgical resection and reconstruction for rare thoracic cancers.

Background: Complex surgical resection and reconstruction for rare thoracic cancers (RTCs) represent a major challenge, given their very low frequency, extreme variability of presentation, multi-modality treatment options and inadequate outcome prediction. We analysed the experience of a tertiary referral centre on a consecutive series of patients with thoracic germ cell tumours, thymomas and sarcomas, with the aim of reporting the long-term outcome by cancer type and complexity of surgical procedures.

Methods: From Jan 2003 to Dec 2018, 768 surgical procedures were performed with curative intent on 644 RTC patients.

Comparison of clinical and oncologic effectiveness between flexible 3-dimensional and bidimensional video-thoracoscopic surgery for lung cancer.

Background: Three-dimensional (3D) vision systems are available for video-assisted thoracic surgery (VATS). It is unclear whether 3D-VATS is superior to bidimensional (2D) VATS systems.

Methods: We analyzed patients who received 3D-VATS ( = 171) or 2D-VATS ( = 228) lobectomy in a single institutional retrospective comparative study of 399 patients with resectable lung cancer conducted from June 2012 to December 2017.

The transmanubrial osteomuscular-sparing approach: a valuable adjunct to the head and neck surgical armamentarium.

Purpose Of Review: To describe and popularize the transmanubrial osteomuscular-sparing approach (TOSA) outside its original thoracic surgical field of application, based on the consideration that it could be of interest for the management of a number of head and neck cases in both elective and emergent scenarios.

Recent Findings: The main advantages of TOSA compared with transclavicular techniques are its superb exposure of anatomic structures located at the level of the cervicothoracic junction, and superior postoperative aesthetic and functional outcomes. Recently, a number of studies have described the association of TOSA with other minimally invasive approaches, such as video-assisted thoracoscopic surgery and robotic hybrid approaches, with the aim of avoiding association of the transmanubrial route with anterior/posterior thoracotomies, or more extended surgeries, such as the trapdoor or hemiclamshell procedures.

Extra-pleural pneumonectomy.

The extra-pleural pneumonectomy (EPP) is a standardised surgical procedure born for pleural tuberculosis and later used in pleural cancer treatment, especially in malignant pleural mesothelioma (MPM). This systematic review aimed to focus on the actual overall EPP role in surgical oncology. The literature search was performed from January 1985 to January 2018 In PubMed, Embase, and Cochrane according to PRISMA protocol.

Lung metastasectomy in adenoid cystic cancer: Is it worth it?

Background And Purpose: Adenoid cystic carcinoma (ACC) of salivary glands is characterized by long-term distant metastasis, most commonly in lungs. No agreement has been reached about the role of surgical treatment of pulmonary lesions. We evaluated the long-term results of lung metastasectomy for ACC in order to identify factors that should be taken into account in selecting patients eligible for surgery and treatment planning.

Pitfalls in oncology: a unique case of thoracic splenosis mimicking malignancy in a patient with resected breast cancer.

Thoracic splenosis (TS) is a condition of autotransplantation of splenic tissue into the pleural cavity after thoraco-abdominal trauma, with diaphragmatic and spleen injury. It is usually asymptomatic and discovered as an incidental finding at imaging performed for other reasons. Its differential diagnosis regards different benign and malignant conditions and should be discerned avoiding invasive procedures.

Baseline C-reactive protein level predicts survival of early-stage lung cancer: evidence from a systematic review and meta-analysis.

Purpose: The prognostic impact of baseline C-reactive protein (CRP) in non-small-cell lung cancer (NSCLC) is debated. To evaluate this issue, we performed a systematic review and meta-analysis to explore the role of CRP value in predicting early-stage NSCLC survival.

Methods: Ten articles on early-stage NSCLC were eligible and included in our study.

Diagnosis and management of typical and atypical lung carcinoids.

An estimated 20% to 30% of all neuroendocrine tumours originate in the bronchial tree and lungs. According to the 2015 World Health Organization categorization, these tumours are separated into four subtypes characterized by increasing biological aggressiveness: typical carcinoid, atypical carcinoid, large-cell neuroendocrine carcinoma and small-cell carcinoma. Although typical and atypical lung carcinoids account for less than 1-5% of all pulmonary malignancies, the incidence of these neoplasms has risen significantly in recent decades.
