Characteristics, management, and outcomes of patients with lung cancer admitted to a tertiary care intensive care unit over more than 20 years.

Rationale: The prognosis of patients with lung cancer admitted to the intensive care unit (ICU) is often perceived as poor. We described the characteristics, management, and outcomes of critically ill patients with lung cancer and determined the predictors of mortality.

Methods: We retrospectively studied patients with lung cancer who were admitted to the ICU of a tertiary care hospital between 1999 and 2021 for the reasons other than routine postoperative care.

A Comparison Between the Complications of Laparoscopic and Open Gastrostomy Tube Insertions: A Single-Center Study From Riyadh, Saudi Arabia.

Background and objective Gastrostomy is a procedure that involves placing a feeding tube through the abdominal wall into the stomach to provide nutritional support. There are several modes of gastrostomy tube insertion including laparoscopic-assisted gastrostomy (LAG), percutaneous endoscopic gastrostomy (PEG), and open gastrostomy (OG) procedure, among others. Although it is a widely performed procedure, limited data is available regarding gastrostomy in Saudi Arabia, specifically among the pediatric population.

A data completion method for identifying pollution intrusion in aquifers.

The data completion method combined with the modeling of water flow and solute transport in saturated porous media is used twice to identify the extent of polluted water intrusion from the downstream boundary of an aquifer. The aim of this work is to solve the problem even though data are missing on some of the boundaries, by exploiting the fact that there are over specified data on the other boundaries. Indeed, it is assumed that the flow and the water head are known on the upstream boundary while the pollutant concentrations are known on the downstream boundary.
