Article Synopsis
  • Minimally invasive techniques, including robotic and laparoscopic surgery, are gaining traction in hepatobiliary surgery due to improved short-term outcomes compared to traditional open surgery.
  • These methods are associated with reduced blood loss, shorter hospital stays, and similar oncologic results, making them a viable option for various liver-related surgeries.
  • While robotic surgery shows advantages like less bleeding and a shorter learning curve, further research is needed on its cost-effectiveness and the development of specialized training programs.

Sustainable cities are crucial in establishing effective waste management systems and minimizing environmental pollution. For cities to be sustainable, different aspects need to be considered, such as technological development, clean energy usage, and energy efficiency. However, taking the most important actions is essential because of the very high cost that will arise, and this situation causes countries to have budget deficit problems.

Navigational bronchoscopy is increasingly used to target peripheral pulmonary nodules using electromagnetic navigational platforms (ENB), fluoroscopic navigation, or robotic-assisted bronchoscopy. The selection of equipment largely depends on the availability of technology, expertise, and the characteristics of the nodule and patient. Radial EBUS (r-EBUS) is often combined with these techniques for real-time confirmation of the nodule location.

Hospitals need to identify issues of greater importance on waste management because the implementation of many different strategies may lead to an unconscious increase in costs. Accordingly, the purpose of this study is to define the most effective waste management strategies in the service industry. For this purpose, a novel fuzzy decision-making model is proposed that has two different stages.

This article presents a comparative analysis of the determinants of hydropower for European economies using Golden Cut oriented Quantum Spherical fuzzy modelling and causality analysis in 24 European countries over the period 2001-2020. The indicators chosen for the analysis are inflation, population, GDP per capita, CO2 and hydropower consumption. The analysis shows that the selected groups of countries are characterised by an inverse relationship between GDP per capita and hydropower consumption, suggesting a bi-directional causal relationship, which also confirms the novelty of this paper.

Xanthogranulomatous cholecystitis (XGC) and gallbladder carcinoma (GBC) are rare diseases with several similarities. This study aimed to evaluate the utility of the systemic immune inflammatory index (SII), a novel index that more accurately depicts inflammatory and immunological balance, in distinguishing between XGC and GBC. This retrospective study included 33 XGC, 22 GBC patients diagnosed according to histopathological findings and 33 age-sex-matched healthy controls at Hacettepe University Faculty of Medicine, General Surgery Department.

Background: : Measurement of tissue characteristics such as the longitudinal relaxation time (T1) provides complementary information to the volumetric and surface based structural analyses. We aimed to investigate T1 relaxation time characteristics in healthy aging via an exploratory design in the whole brain. The data processing pipeline was designed to minimize errors related to aging effects such as atrophy.

Background: Resection of metastatic hepatic tumors of breast cancer may result in the acceleration of hepatic and extrahepatic tumor progression due to the microenvironmental circulation of chemokines. This study aimed to investigate the effect of hepatectomy on a large panel of chemokines, liver regeneration, and myeloid cell levels in an experimental breast cancer model.

Methods: The 4T1 breast cancer cells were inoculated, and 30% to 40% hepatectomy was performed.

Article Synopsis
  • Current medical guidelines recommend specific procedural volumes for interventional pulmonology fellows to gain competency in electromagnetic navigational bronchoscopy (ENB), emphasizing the importance of structured training.
  • A multicenter study involving 26 fellows showed that the median number of ENB procedures required to reach competency is 4, but it can range from 2 to 15, indicating substantial variability.
  • The study identified six periprocedural complications, mostly occurring before fellows achieved competency, and highlighted the value of virtual assessments for determining competency, although further research is needed.

Immunosuppressive therapy is a double-edged sword and causes a risk for some complications, such as opportunistic infections and posttransplant lymphoproliferative disease. The most likely risk factors for posttransplant lymphoproliferative disease are Epstein-Barr virus serology mismatch, prolonged and high viral load for Epstein-Barr virus, higher doses of immunosuppressive therapy, and cytomegalovirus infection. Transplant recipients who are seropositive for Epstein-Barr virus show a lower risk for posttransplant lymphoproliferative disease than seronegative recipients.
