Caregivers' Perspective and Burden of the End-of-Life Phase of Patients with Glioblastoma: A Multicenter Retrospective Study.

Background: Glioblastoma is the most common aggressive primary brain tumor in adults. Changes in cognition, personality, and behavior of patients as well as side effects of treatments cause unique challenges for providing care and may impact caregiver burden in different ways.

Methods: This retrospective study included 45 patients with a diagnosis of glioblastoma treated between January 2022 and June 2023 in 2 neurosurgical departments.

New Trend in Craniovertebral Junction Surgical Strategy: Technical Note for the Treatment of Hangman's Fractures Through a Minimally Invasive Approach.

Introduction: The reduction, stabilization, and maintenance of alignment are the main goals in the surgical treatment of unstable hangman's fractures. The choice of the surgical strategy remains poorly standardized; anterior and/or posterior fusion could be performed; and none of the available clinical studies in the literature have shown significant differences in outcomes or complication rates. Vertebral anatomy, age, comorbidities, patient factors, and surgical experience may guide the treatment choice.

Pedicle Screw Placement Aided by C-Arm Fluoroscopy: A "Nevermore without" Technology to Pursue Optimal Spine Fixation.

The surgical technique and the intraoperative technology that support spinal pedicle screw placement have consistently evolved over the past decades to decrease the misplacement rate of pedicle screws. We retrospectively evaluated our case series by analyzing the period 2016-2020. Patients undergoing pedicle screw fixation for cervical, thoracic, or lumbar spine degenerative diseases have been included.

Metabolic impact of high lipid low dextrose parenteral nutrition.

Background: Parenteral nutrition (PN) containing 100% soybean oil lipids and high amounts of dextrose may lead to liver dysfunction and hyperglycemia. Mixed lipids have less pro-inflammatory components, so higher doses may be given to decrease the amount of dextrose provided. The purpose of this study is to provide a descriptive analysis of patients who received PN with high mixed lipid and low dextrose content versus PN with lower 100% soybean oil lipid and high dextrose content.

High lipid, low dextrose parenteral nutrition allows patient to achieve nutritional autonomy: A case report.

Introduction: Prolonged use of parenteral nutrition can eventually lead to liver abnormalities. Causative factors include decreased enteral stimulation, high intakes of intravenous dextrose, proinflammatory 100 % soybean oil-based lipids, and increased burden on liver through 24-h infusions. We present a case report of a patient who received parenteral nutrition modifications to address liver dysfunction.

Resistant starch improves cardiometabolic disease outcomes: A narrative review of randomized trials.

Healthy dietary patterns with adequate fiber improve cardiometabolic (CM) outcomes and attenuate disease progression. Resistant starch (RS) is a fermentable fiber that affects CM outcomes; however, studies are heterogeneous and inconsistent. Thus, the purpose of this narrative review is to assess the impact of RS intake by type and amount on CM outcomes while considering subject characteristics and trial duration.

Evaluation of adequacy of levo-thyroxine dosage in patients with differentiated thyroid carcinoma: correlation between morning and afternoon TSH determination.

Purpose: The aim of this study was to judge the reliability of evaluating thyroid-stimulating hormone (TSH) and free thyroxine (f-T4) in the morning and afternoon in differentiated thyroid carcinoma (DTC) patients.

Methods: We evaluated 153 DTC patients, aged 61 ± 13 years, in active follow-up in our center after primary treatments and under stabilized levo-thyroxine (L-T4) posology. In each patient, morning and afternoon examinations were performed 1-3 months apart.

Malignant teratoma in Klippel-Feil syndrome: a case report and review of the literature.

Introduction: Klippel-Feil syndrome is characterized by a congenital fusion of cervical vertebrae. Intracranial teratomas are nongerminomatous germ cell tumors and they account for 0.3 to 0.

Penetrating head injury by a stone: case report and review of the literature.

Traumatic intracranial penetration of foreign objects of non-missile intracranial nature rarely occurs. Haemorrhages, major vascular injury and contusions can be causes of death in early stage, epileptic seizures and infections are possible complications in later stages. Complete excision of the foreign body should be performed.

PACAP and VIP affect NF1 expression in rat malignant peripheral nerve sheath tumor (MPNST) cells.

In our previous study we have identified PACAP, VIP and their receptors in rat malignant peripheral nerve sheath tumor (MPNST) cells, thus showing anti-apoptotic roles. Recently it has been shown that the tumor suppressor neurofibromin, encoded by the Neurofibromatosis type I (NF1) gene, promotes MPNST cells sensitivity to apoptosis after serum withdrawal. In the present study we investigated whether PACAP or VIP negatively regulate NF1 expression under normal or serum-dependent pro-apoptotic culture conditions.

Five-level one-piece laminoplasty for extensive tumors of the lumbar spine.

The authors describe the surgical method and results of nonexpansive one-piece multivel laminoplasty of the whole lumbar spine, for microsurgical resection of extensive spinal tumors. This technique allows a very comfortable approach to the dura and intradural content, as well as a perfect replacement of the posterior spinal arch with supporting elements and an optimal reconstruction of the spinal anatomy. A nonexpansive whole lumbar one-piece laminoplasty was performed for resection of extensive multilevel lumbar tumors.

[Effect of heat treatment on the structure of a Cu-Zn-Al-Ni system dental alloy].

This article characterizes the structural phases present in the copper-based metallic alloy system "Cu-Zn-Al-Ni" developed for dental use, and relates those phases to other properties. The characterization was obtained after casting (using the lost wax process), and after heat treatment. In order to obtain better corrosion resistance by changing the microstructure, the castings were submitted to 30, 45 and 60 minutes of heat treatment at the following temperatures: 750 degrees C, 800 degrees C, and 850 degrees C.
