Insertion depth of left-sided double-lumen endobroncheal tube: A new predictive formula.

Background: In the field of thoracic anesthesia, it is well-established practice that the insertion depth of left-sided double-lumen tube (LDLT) is achieved after checking its position via fiberoptic bronchoscopy (FOB). Several studies have shown positive correlation between body height (BH) and the optimal insertion depth of a LDLT. Each of these studies has developed a formula for proper insertion depth of the LDLT.

The Use of Antifibrotic Recombinant nAG Protein in a Rat Liver Fibrosis Model.

Objectives: The "nAG" protein is the key protein mediating the regeneration of amputated limbs in salamanders. The senior author (MMA) developed the original hypothesis that since "nAG" is a "regenerative" protein, it must be also an "antifibrotic' protein. The antifibrotic properties were later confirmed in a rabbit skin hypertrophic scar model as well as in a rat spinal cord injury model.

Appearance of Population, Intervention, Comparison, and Outcome as research question in the title of articles of three different anesthesia journals: A pilot study.

Background: It is well known in the evidence-based medicine practice that framing the research question is the most important and crucial part of the research integrity. Population, Intervention, Comparison, and Outcome (PICO) is a specialized framework used by most researchers to formulate a research question and to facilitate literature review. The aim of this study is to investigate the representation of the PICO frame in the title of published articles in three different anesthesia journals.

Effect of drinking Arabian Qahwa on fractional exhaled nitric oxide levels in healthy nonsmoking Saudi adults.

Objectives: Fractional exhaled nitric oxide (FENO) is an emerging marker of inflammation in respiratory diseases. However, it is affected by a number of confounding factors. We aimed to study the effect of drinking Arabian Qahwa on FENO in non-smoking Saudi healthy adults.
