Objective: This study aimed to peruse the alteration of the position of the optic strut (OS) according to the anterior clinoid process (ACP) pneumatization.
Methods: This retrospective study conducted on cone-beam computed tomography images of 400 patients with a mean age of 36.49±15.91 years.
Results: Anterior clinoid process length, width, and angle were measured as 10.56±2.42 mm, 5.46±1.31 mm, and 42.56±14.68 degrees, respectively. The tip of ACP was measured as 6.60±1.50 mm away from the posterior rim of OS. In the 631 sides (78.87%) did not have ACP pneumatization. In the cases with ACP pneumatization, three different configurations were identified as follows: Type 1 in 71 sides (8.87%), Type 2 in 56 sides (7%), and Type 3 in 42 sides (5.23%). Relative to ACP, the location of OS was determined as follows: Type A in 29 sides (3.64%), Type B in 105 sides (13.12%), Type C in 344 sides (43%), Type D in 289 sides (36.12%), and Type E in 33 sides (4.12%). The spread of data related to the attachment site of OS according to the presence or absence of ACP pneumatization showed that the location of OS was affected by ACP pneumatization ( P <0.001). In ACPs with pneumatization, the frequency of OS position relative to ACP was found as follows: Type A in none of sides (0%), Type B in 8 sides (7.6%), Type C in 53 sides (15.4%), Type D in 88 sides (30.4%), and Type E in 20 sides (60.6%).
Conclusions: The main finding of this study was that the location of OS relative to ACP was affected by ACP pneumatization. In ACPs with pneumatization, OS was located more posteriorly compared with ACPs without pneumatization.

Aim: Complete mesocolic excision (CME) is an oncologically driven technique for treating right colon cancer. While laparoscopic CME is technically demanding and has been associated with more complications, the robotic approach might reduce morbidity. The aim of this study was to assess the safety of stepwise implementation of robotic CME.

Background: Vertebrogenic pain is a documented source of anterior column chronic low back pain (CLBP) that stems from damaged vertebral endplates. Nociceptive signals are transmitted by the basivertebral nerve (BVN) and endplate damage is observed as Type 1 or Type 2 Modic changes (MC) on magnetic resonance imaging (MRI). The clinical impact and safety of intraosseous radiofrequency ablation of the BVN (BVNA) for the treatment of vertebrogenic pain has been demonstrated in three prospective clinical trials (two randomized and one single-arm study).

The pore structure of shale is a key factor affecting the occurrence and flow of shale gas, and fractal dimensions can be used to quantitatively describe the complexity of the shale pore structure. In this study, the Leping Formation shale in the Junlian block of the southern Sichuan Basin was investigated. The pore structure characteristics of this shale were examined via low-pressure CO adsorption (LP-COA) and low-temperature N adsorption (LT-NA) methods via field emission scanning electron microscopy (FE-SEM), shale geochemistry, and mineral composition analysis.

Background And Aims: Accumulating evidence indicates that reducing high blood pressure (BP) prevents dementia and mild cognitive impairment (MCI). Furthermore, although diabetes is a risk factor for dementia and MCI, there is uncertainty of the effect of intensive glucose control on these endpoints. This study aimed to determine the effects of BP-lowering (vs placebo) and intensive glucose-lowering (vs standard control) treatments according to baseline cognition and other characteristics on dementia and cognitive decline (CD) in people with type 2 diabetes mellitus (T2DM).

This is a novel case of idiopathic chylopericardium and chylothorax in a young male who had no significant medical history. He first presented with dyspnea due to idiopathic chylopericardium, which was refractory to medical and surgical treatments, including a medium-chain triglyceride diet, octreotide, and video-assisted pericardial window. The chylopericardium persisted and progressed to concomitant left-sided chylothorax.
