Comparison of Vitamin D3 Supplementation Doses of 1,000, 2,000, 4,000 and 8,000 IU in Young Healthy Individuals.

Background/aim: Low levels of vitamin D are a widespread global issue. This study aimed to determine the optimal vitamin D3 supplementation dose for healthy young adults by comparing the effectiveness of gradually increasing cholecalciferol doses over two years.

Patients And Methods: Thirty-five volunteers participated in a two-season pilot study conducted from October to April to avoid sunlight-induced vitamin D3 synthesis.

The Behavior of Nasopharynx Malignancies: a Retrospective Study in a Ten-Year Sample.

Objectives: Malignant tumors of the nasopharynx make up 3% of malignancies in the ENT area. The most common nasopharyngeal malignancy is nasopharyngeal carcinoma (NPC), followed by lymphomas. Other nasopharyngeal tumors are very rare.

Newborn Hearing Screening - An Implementation Analysis.

Background/aim: Hearing impairment affects a small but significant percentage of newborns (0.1-0.4%).

The impact of obesity, age, and gender on plasmatic levels of selected glycoprotein biomarkers and miRNA-499 in OSA patients.

Background: The current obstructive sleep apnea (OSA) diagnostic uses polysomnography or limited polygraphy and requires specialized personnel and technical equipment. Glycoprotein biomarkers and microRNAs are being explored as a possible new method for screening. We aimed to evaluate whether certain biomarkers and microRNA, previously identified as related to OSA, could be influenced by factors such as gender, age, and obesity level in patients with OSA.

A Case Study of Vitamin D Supplementation Therapy and Acute Respiratory Tract Infection.

Background: Low serum concentrations of 25-hydroxyvitamin D correlate with higher susceptibility to acute respiratory tract infections (ARTIs). The case study presented here aims at sheding light on the correlation between vitamin D levels, the vitamin D supplement dose, and the incidence of ARTIs.

Case Report: A 23-year-old female patient with a vitamin D insufficiency was able to successfully increase her vitamin D levels from 45.
