Objective: To determine the seroprevalence of Helicobacter.pylori antibodies in asymptomatic healthy population.
Methods: Convenient sampling was done in asymptomatic healthy individuals accompanying the patients who had no previous history of epigastric pain. Venous blood was collected from individuals and sera separated. Enzyme-linked immunosorbent assay (ELISA) was used to determine H. pylori IgG antibodies in all sera.
Results: A total of 396 samples were collected. H. pylori antibodies were found in 201 (51%) individuals. A 46% seroprevalence was found in subjects 15-20 years of age, which gradually increased with age and reached to .61% in subjects up to 50 years of age. Subjects > 40 years had higher antibody response than those < 40 years. There was no significant association between presence of H. pylori antibodies and dietary habits and sources of drinking water. H. pylori antibodies in female smokers were found in 9% and in non smoking females were 91% but no such difference was found in male smokers or non-smokers.
Conclusion: Infection with H. pylori is prevalent in the healthy individuals of Makkah, Saudi Arabia. Infection is acquired in the early age and reaches up to 61% as the age advances. A nation wide epidemiological study is warranted to determine the seroprevalence of H. pylori in Saudi Arabia.

Background: Ethics is based on moral principles that should be the foundation for every healthcare decision, however, ethical concepts can often be challenging to define in specific clinical scenarios. There are several instances where a practising clinician often finds it difficult to make a proper decision despite maintaining integrity and professionalism. The objective of the present study was to explore the ethical dilemma faced by orthodontists practicing in Saudi Arabia concerning orthodontic treatment.

Background: Ultrasonographic optic nerve sheath diameter (ONSD) is a satisfactory noninvasive intracranial pressure (ICP) monitoring test. Our aim was to evaluate ONSD as an objective screening tool to predict and diagnose ICP changes early in sepsis-associated encephalopathy (SAE).
Methods: Our prospective observational study was conducted on patients with sepsis, and after intensive care unit (ICU) admission, the time to diagnose SAE was recorded, and patients were divided into a non-SAE group including conscious patients with sepsis and a SAE group including patients with sepsis with acute onset of disturbed conscious level.

The hydrothermal synthesis is presented of copper-doped carbon dots (Cu-CDs) from citric acid, urea, and copper chloride, resulting in blue-fluorescent particles with stable emission at 438 nm when excited at 340 nm. Through comprehensive spectroscopic and microscopic characterization (FTIR, XPS, UV, and HRTEM), the Cu-CDs demonstrated remarkable stability across varying pH levels, ionic strengths, temperatures, and UV exposure. Notably, Cu-CDs exhibit ultra-sensitive and selective detection of hexavalent chromium [Cr(VI)] ions in aqueous environments driven by fluorescence quenching.
