  • * A retrospective evaluation of 16 patients from January 2017 to January 2024 revealed significant differences in 30-day mortality rates between elective and emergency OSCs, with independent mortality factors including cardiac shock and low hematocrit levels.
  • * The average ICU stay was 8.7 days, with a mean hospital stay of 17.3 days and a 5-year overall survival rate of 43.75%, indicating that further research is needed to understand the implications of using EVAR beyond established guidelines.

Objectives: Minimally invasive anatomic segmentectomy for the resection of pulmonary nodules has significantly increased in the last few years. Nevertheless, there is limited evidence on the safety and feasibility of robotic segmentectomy compared to video-assisted thoracic surgery. This study aimed to compare the real-world early outcomes of robotic and video-thoracoscopic surgery in anatomic segmentectomy.

Article Synopsis
  • The study aimed to identify the electrical characteristics of nonrecurrent inferior laryngeal nerves (NRILNs) during thyroid surgeries using intraoperative neuromonitoring (IONM) and look for associated vascular anomalies.
  • Out of 7865 thyroidectomy patients, 42 had NRILNs, with most cases detected through specific EMG signs and difficulties identifying the recurrent laryngeal nerve.
  • The findings showed a 0.53% prevalence of NRILNs, with a significant percentage having vascular anomalies, and suggest early detection methods during surgery to reduce the risk of nerve injury.

Article Synopsis
  • Testing the biocompatibility of dental materials is crucial and this study focused on four specific materials: Mineral Trioxide Aggregate, Biodentine, Harvard BioCal-CAP, and Oxford ActiveCal PC.
  • The evaluation used zebrafish embryos and larvae to assess survivability, hatching rates, and apoptosis through various toxicity tests.
  • Results indicated that higher concentrations of these materials negatively affected survival and hatching, with Biodentine and Oxford ActiveCal PC showing better biocompatibility than Mineral Trioxide Aggregate.

Development of the multilayered cerebral cortex relies on precise orchestration of neurogenesis, neuronal migration, and differentiation, processes tightly regulated by microtubule dynamics. Mutations in tubulin superfamily genes have been associated with tubulinopathies, encompassing a spectrum of cortical malformations including microcephaly and lissencephaly. Here, we focus on γ-tubulin, a pivotal regulator of microtubule nucleation encoded by TUBG1.

Objective: The aim of this study is to evaluate the relationship between semen parameters, complete blood count, and hormone levels on the day of spermiogram.

Methods: Semen parameters of 230 patients who were examined for full blood count test and hormone levels on the day of spermiogram were included in the study. Patients were grouped according to the total motile sperm count (TMSC), semen parameters, hemogram, and hormone levels were compared between groups.

Background: Adrenal gland injury (AGI) associated with trauma is an uncommon and often overlooked condition. This study aimed to evaluate the frequency of AGI in individuals with severe trauma injuries and investigate the outcomes of patients with AGI.

Methods: All patients admitted to a tertiary trauma referral center under the trauma protocol who had a computed tomography (CT) scan between January 2012 and January 2023 were analyzed retrospectively.

Background: The funnel technique, the hybrid assembly of a thoracic and abdominal aortic endograft, is advantageous for frail patients where efficient oversizing is not possible for infrarenal wide aortic necks over 34 mm. We sought to determine the advantages and disadvantages of the Funnel-endovascular aneurysm repair (EVAR) technique using 60 mm length thoracic endograft.

Methods: This retrospective study included 22 patients, all frail with high comorbidities, who were operated on with the Funnel technique using the 60 mm Lifetech Ankura thoracic endograft, in 7 urgent and 15 elective cases from January 2018.

The aortic valve (AV) is crucial for cardiovascular (CV) hemodynamic, impacting cardiac output (CO) and left ventricular volumetric flow rate (LVQ). Its nonlinear behavior challenges standard LVQ prediction methods as well as CO one. This study presents a novel approach for modeling the AV in the CV system, offering an improved method for estimating crucial parameters like LVQ across various AV conditions, including aortic stenosis (AS).

To investigate whether there is a difference in mean diffusivity (MD) and fractional anisotropy (FA) values in the auditory pathways of neurofibromatosis type 1 patients with and without focal areas of abnormal signal intensity (FASI) compared to healthy controls by using diffusion tensor imaging (DTI). Patients were classified as group 1 with focal areas of abnormal signal intensity in the brainstem, group 2 without focal areas of abnormal signal intensity, and healthy control group 3 according to the MRI findings. Mean diffusivity and fractional anisotropy values of lateral lemniscus, inferior colliculus, corpus geniculatum mediale, Heschl gyrus, and brainstem were compared between groups.

Background: The primary surgical approach for removing adrenal masses is minimally invasive adrenalectomy. Recognition of anatomical landmarks during surgery is critical for minimizing complications. Artificial intelligence-based tools can be utilized to create real-time navigation systems during laparoscopic and robotic right adrenalectomy.

Introduction: Huntington's disease (HD) is known as a neurodegenerative disease with movement disorder and cognitive impairment; autonomic involvement is also becoming common in some recent studies. The aim of this study is to demonstrate the presence of cardiac autonomic involvement in HD patients.

Method: Time and frequency domain parameters obtained from the 24-h Holter ECG(hECG) were compared between 20 HD patients and 20 healthy control subjects.

Background: Intraoperative neural monitoring (IONM) has been utilized for a variety of thyroid pathologies, including papillary thyroid carcinoma (PTC). Remnant thyroid tissue following total thyroidectomy (TT) in patients with PTC is associated with increased recurrence. The aim of this study is to investigate whether the use of IONM in PTC surgery has an impact on the completeness of thyroidectomy.

Tumor necrosis factor-α (TNF-α) is a ligand that induces both intrinsic and extrinsic apoptotic pathways in HeLa cells by modulating complex gene regulatory mechanisms. However, the full spectrum of TNF-α-modulated epitranscriptomic mA marks is unknown. We employed a genomewide approach to examine the extent of mA RNA modifications under TNF-α-modulated apoptotic conditions in HeLa cells.

The hybrid mock circulatory loop (hMCL) serves as a crucial hemodynamic simulation tool, offering exceptional flexibility, controllability, and reproducibility for investigating the mechanisms underlying cardiovascular diseases (CVD) in a controlled environment, circumventing the limitations of live organism studies. This paper introduces a novel design and control strategy for hMCL, introducing a novel left ventricle volume-elastance (LVVE) equation that unifies the autoregulation of the Frank-Starling mechanism (FSM) with left ventricle contractility (LVC). LVVE establishes a dynamic link between left ventricular volume (LVV) and LVC, inherently satisfying the regulatory relationship between left ventricular pressure (LVP) and LVV through a mathematical equation.

Aim: Blunt traumatic thoracic aortic injury (BTAI) is a highly fatal surgical emergency and is treated with endovascular procedures. We aimed to analyze and report the early and midterm outcomes of surgeon-modified fenestrated stent-grafts (SMFSG) compared with other conventional endovascular methods in patients with BTAI repaired with zone 2 endovascular surgery.

Materials And Methods: Before and after the study was performed, from January 2015 to January 2020 for a period in which conventional endovascular treatments were used and from January 2020 to January 2023 for the second period in which the SMFSG technique was used.
