Background: We aimed to examine the efficacy of intravenous vitamin C (IV-VC) in the treatment of hospitalized patients with moderate or severe COVID-19.

Method: We conducted a single-center and retrospective study including patients with COVID-19 diagnosis who were hospitalized. Patients were categorized into three groups as those who received low-dose (LDVC group, 2 g/day, n = 183) or high-dose IV-VC (HDVC group, 25 g/day, n = 41) and who did not receive IV-VC (control group, n = 46).

Objectives: To analyse impact of segmentectomy on oncological outcomes of different peripheral early-stage lung adenocarcinoma patterns.

Methods: Retrospective multicentre study including patients who underwent either lobectomy or segmentectomy in 6 European centres from 2015 to 2021, for ≤2 cm pathological peripheral lung adenocarcinoma. Overall and disease-free survivals were assessed by cox-regression and lung cancer-specific survival by competing regression analyses to adjust for patient- and tumour-related factors both in the entire dataset and the in aggressive adenocarcinoma patterns dataset.

Article Synopsis
  • Pulmonary endarterectomy is a surgical option for chronic thromboembolic pulmonary hypertension (CTEPH) that can potentially cure the condition, and this study looked at factors influencing patient outcomes post-surgery.
  • The study analyzed data from 834 patients who underwent surgery between March 2014 and January 2024, revealing a 7.8% in-hospital mortality rate and highlighting that older patients (≥70 years) had a significantly higher mortality rate compared to younger patients (<70 years).
  • Key predictors of mortality included age, length of ICU stay, the Charlson Comorbidity Index, and six-minute walk distance, with the findings indicating that while elderly patients faced higher risks, the surgery could still lead

As our tertiary-level trauma center is close to an industrial zone and associated international port, industrial injuries are seen more often than is expected in routine practice. The aim of this study was to present the demographic data, treatment options, and changes in work-life of patients with foot and ankle injuries due to a forklift accident, and to determine the factors affecting the clinical outcome. The study was conducted in our university hospital and included patients who presented with a foot and ankle injury resulting from a forklift accident.

Objective: Macroscopic complete resection (MCR) is the recommended surgical strategy in malignant pleural mesothelioma. Our objective was to analyze whether MCR influences survival in malignant pleural mesothelioma.

Methods: Between 2002 and 2016, 154 patients underwent pleurectomy decortication (n = 90), extrapleural pneumonectomy (n = 42), or exploratory/diagnostic procedures (n = 22) in a single institution.

Objective: To understand the dynamic relations among tobacco withdrawal symptoms to inform the development of effective smoking cessation treatments. Dynamical system models from control engineering are introduced and utilized to evaluate complex treatment effects. We demonstrate how dynamical models can be used to examine how distinct withdrawal-related processes are related over time and how treatment influences these relations.

OBJECTIVE The semisitting position of a patient confers numerous advantages in various neurosurgical procedures, but venous air embolism is one of the associated complications of this position. To date, no prospective studies of the relationship between the degree of head elevation and the rate and severity of venous air embolism for patients undergoing a procedure in this position have been performed. In this study, the authors compared changes in the severity of venous air embolism according to the degree of head elevation (30° or 45°) in patients undergoing an elective cranial neurosurgical procedure in the semisitting position.

Rural residents can be exposed to agricultural pesticides through the proximity of their homes to crop fields. Previously, we developed a method to create historical crop maps using a geographic information system. The aim of the present study was to determine whether crop maps are useful for predicting levels of crop herbicides in carpet dust samples from residences.

The temporalis muscle flap is a useful flap for the reconstruction of oral ablative defects. A complication of its use that was overlooked was the crater-like defect created when the muscle is stripped from its attachment on the temporal fossa. The cold-cure acrylic we use is Palacos R-40 with Gentamicin (Heraeus Kulzer GmbH).

The 1H NMR chemical shifts and NOEs of hydroxy protons in Lewis X trisaccharide, beta-D-Galp-(1-->4)[alpha-L-Fucp-(1-->3)]-beta-D-GlcpNAc, and Lewis Y tetrasaccharide, alpha-L-Fucp-(1-->2)-beta-D-Galp-(1-->4)[alpha-L-Fucp-(1-->3)]-beta-D-GlcpNAc, were obtained for 85% H2O/15% (CD3)2CO solutions. The OH-4 signal of Galp in Lewis X and OH-3, OH-4 signals of Galp, and OH-2 signal of Fucp linked to Galp in Lewis Y had chemical shifts which indicate reduced hydration due to their proximity to the hydrophobic face of the Fucp unit linked to GlcpNAc. The inter-residue NOEs involving the exchangeable NH and OH protons confirmed the stacking interaction between the Fucp linked to the GlcpNAc and the Galp residues in Lewis X and Lewis Y.
