Mehdi Basaki — Tue, 26 Nov 2024 06:26:51 +0000

Introduction: Infectious diseases continue to significantly affect global human health. Conducting infection diagnostic tests can be difficult due to limited resources, time limitations, or the inadequacy of current diagnostic techniques. There is a growing interest in developing diagnostic methods through the analysis of exhaled air, as breath sampling is non-invasive, safe, and convenient. Volatile organic compounds (VOCs) present in exhaled air provide insights into the metabolic and biophysical processes associated with various diseases. This review highlights recent advancements in breath-based diagnosis for respiratory infections, including those caused by the influenza virus, SARS-CoV-2, Mycobacterium tuberculosis, Pseudomonas aeruginosa, and Aspergillus fumigatus. Furthermore, this review also examines the contemporary viewpoint on diagnosing two significant infections: Helicobacter pylori and malaria.

Conclusion: Certain volatile organic compounds (VOCs) linked to respiratory conditions are specifically and often associated with multiple infectious diseases, indicating that breath analysis could be a valuable approach for creating diagnostic tools. However, existing challenges encompass the absence of standardized protocols for collecting and analyzing breath samples, as well as a deficiency in validation studies. Additional research is essential to broaden the use of breath analysis in clinical practice.

Malihe Hasanzadeh, Roya Safarkar — Tue, 26 Nov 2024 06:32:37 +0000

Introduction: Ulcerative colitis, also known as intestinal colitis, is a relatively common and chronic condition characterized by inflammation of the large intestine. This disorder falls under the category of inflammatory bowel diseases and shares notable similarities with Crohn's disease The large intestine is responsible for extracting nutrients from undigested food while expelling waste through the rectum or anus in the form of feces Humans are almost identical in their genetic sequence, but small differences in our DNA lead to tremendous phenotypic diversity among the human population. The various types of microbial communities and their genetic material (the microbiome) present in the human body play a crucial role in health and disease. Numerous studies have established a link between ulcerative colitis and the human microbiome.

Conclusion: Changes in the microbiome's diversity can be one of the reasons for the development of ulcerative colitis. Investigating the relationship between the microbiome and ulcerative colitis can suggest new treatment methods such as stool transplantation.
