Effects of Variable Ventilation on Gas Exchange in an Experimental Model of Capnoperitoneum: A Randomized Crossover Study.

Background: The rapid advancement of minimally invasive surgical techniques has made laparoscopy a preferred alternative because it reduces postoperative complications. However, inflating the peritoneum with CO2 causes a cranial shift of the diaphragm decreasing lung volume and impairing gas exchange. Additionally, CO2 absorption increases blood CO2 levels, further complicating mechanical ventilation when the lung function is already compromised.

Prevalence and clinicopathological characteristics of de novo metastatic cancer at a major radiotherapy centre in West Africa: a cross-sectional study.

Background: Cancer is a major public health challenge in West Africa, with a significant proportion of cancer-related deaths attributed to distant metastasis. De novo metastatic cancer (DnMC), where metastasis is detected at diagnosis, presents considerable therapeutic challenges, particularly in limited-resource settings where novel treatments are often unavailable and/or unaffordable.

Aim: To determine the prevalence, incidence and clinicopathological characteristics of patients diagnosed with DnMC at a major radiotherapy center in West Africa.

Optic nerve glioma successfully treated with definitive intensity-modulated radiotherapy in a limited-resource setting: a case report.

Optic nerve gliomas (ONG) are benign central nervous system tumours and the most common tumours of the optic nerve in children, often occurring before age 20. These tumours are slow-growing and can be treated with surgery and/or radiation therapy. Surgical resection is, however, associated with significant morbidity and loss of vision in the affected eye.

Surgery and minimally invasive treatments for uterine fibroids.

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects of surgery and minimally invasive treatments for uterine fibroids.

Dissociative episodes and concurrent heart rate in patients with PTSD - An ecological momentary assessment.

Dissociative symptoms are a frequent complication in posttraumatic stress disorders affecting about a third of all PTSD patients. While theoretical models predict a physiological hypoarousal during posttraumatic dissociations, empirical evidence is lacking. We addressed this by studying spontaneously occurring dissociative symptoms and related heart rate changes in an ecological momentary assessment.
