Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

3D Electrical Impedance Tomography of Regional Ventilation During Jet Ventilation: A Pilot Study

Laryngoscope Investigative Otolaryngology, Volume 11, Issue 4, August 2026.
ABSTRACT Objectives Low‐frequency jet ventilation (LFJV) is commonly used in laryngotracheal surgery when intubation is not feasible. However, limited understanding of regional ventilation and distal airway pressures raises safety concerns and restricts broader adoption.

Increased visceral tissue perfusion with heated, humidified carbon dioxide insufflation during open abdominal surgery in a rodent model. [PDF]

PLoS ONE, 2018
Tissue perfusion during surgery is important in reducing surgical site infections and promoting healing. This study aimed to determine if insufflation of the open abdomen with heated, humidified (HH) carbon dioxide (CO2) increased visceral tissue ...

Robotic‐Assisted Epiphrenic and Mid‐Oesophageal Diverticulectomy: A Tertiary Centre Experience

The International Journal of Medical Robotics and Computer Assisted Surgery, Volume 22, Issue 4, August 2026.
ABSTRACT Background Surgical management of oesophageal pulsion diverticula is advised when symptoms significantly impair quality of life. Robotics can aid in transhiatal dissection in diverticulectomy, but available evidence is limited. Methods A retrospective chart review of all consecutive robotic‐assisted oesophageal diverticulectomies with Heller ...

Carbon Dioxide versus Air Insufflation in Gastric Endoscopic Submucosal Dissection: A Systematic Review and Meta-Analysis of Randomized Controlled Trials [PDF]

Clinical Endoscopy, 2017
Background/Aims Endoscopic submucosal dissection (ESD) with air insufflation is commonly used for the staging and treatment of early gastric carcinoma. However, carbon dioxide (CO2) use has been shown to cause less post-procedural pain and fewer adverse ...

Preoperative Computed Tomography Colonography‐Angiography for Vascular Mapping to Guide and Standardize D3 Lymphadenectomy in Right‐Sided and Transverse Colon Cancer

Annals of Gastroenterological Surgery, Volume 10, Issue 4, Page 1120-1132, July 2026.
This study utilized high‐resolution CT colonography‐angiography to systematically classify vascular branching patterns in 591 patients. We defined four reproducible anatomical patterns each for right hemicolectomy and transverse colectomy, demonstrating that an independent‐origin middle colic artery consistently predicts shorter dissection distances ...

Carbon Dioxide versus Room Air for Colonoscopy: a Single Center Study [PDF]

Afro-Egyptian Journal of Infectious and Endemic Diseases
Background and study aim: Abdominal pain and bloating sensations can occur after colonoscopy. Theoretically, a faster rate of absorption is expected to reduce abdominal pain and bloating when using carbon dioxide (CO2).
