Objectives The literature on health and disease during Ramadan fasting (RF) is widely spread in many journals making it not readily accessible to those interested in the subject. Here, we provide an overview of the research on the interplay of RF with various aspects of well-being published in 2022. Materials and Methods A narrative, nonsystematic review of the international literature from a single major medical online database, PubMed, in one calendar year (2022) was conducted. The search term “Ramadan fasting” was used to retrieve the appropriate records. The relevant literature with substantial data-based content was presented in a concise thematic account, excluding those concerned with diabetes. Results Themes that emerged from the review included the pathophysiology of metabolic changes during RF, nutritional aspects including body composition and energy metabolism, cardiovascular disease and risk factors, renal function and structure, endocrinology (mainly thyroid), neurological disorders, mental health, pregnancy and fetal life, and infections (including COVID). Some miscellaneous clinical themes were identified, such as patients' and professional perspectives. Conclusions In 2022, the medical interest in RF was again widely spread across specialties. Cardiovascular disease and risk factors attract the most interest in terms of original articles and professional guidelines. We hope with this review to present a concise summary of the scholarly work on the subject in this year.

“…On the other, the mechanism of airflow through the nose and sinuses and its effect on the mucosa are overlooked in the pathophysiology of inflammation. Mucociliary transport is known to be directed towards the maxillary sinus ostea and further to the nasopharynx 1,13,14 . At the same time, the role of the airflow direction remains unclear: does it interact with this transport or is it opposite it?…”

We aimed to analyse ostiomeatal complex (OMC) aeration using the computational fluid dynamics (CFD) method of simulation based on human craniofacial computed tomography (CT) scans. The analysis was based on CT images of 2 patients: one with normal nose anatomy and one with nasal septal deviation (NSD). The Reynolds-Average Simulation approach and turbulence model based on linear eddy viscosity supplemented with the two-equation k-$$\omega$$ ω SST model were used for the CFD simulation. As a result, we found differences in airflow velocity through the ostiomeatal complex in patients with a normal nose and those with NSD. In a patient with NSD, the flow is turbulent in contrast to the normal nose (laminar flow). A faster (more intensive) airflow through the OMC was observed in the wider nasal cavity of the patient with NSD than on the narrower side. In addition, we want to emphasise the higher speed of airflow through the apex uncinate process area towards the ostiomeatal complex during exhalation, which, in the presence of secretions in the nose, predisposes to its easier penetration into the sinuses of the anterior group.

ObjectiveThe present study objectived to investigate the influence of Ramadan fasting (RF) on olfactory function.MethodsSixty‐two participants were included in the current prospective study. The odor threshold and identification performances were determined by using the Connecticut Chemosensory Clinical Research Center (CCCRC) test initially (day 0) and on the first and last day (30th) of RF. Body weight (BW)s were measured initially and at the end of the study. The results were analyzed statistically.ResultsThe average of baseline and last‐day BWs were 78.38 ± 12.96 and 78.36 ± 12.39 kg, respectively. No significant difference was determined in terms of BWs (p = .932, p > .05). In the evaluation of CCCRC test outcomes, significant differences were observed in the scores of butanol thresholds (p = .0001), odor identification (p = .0001), food‐related odors identification (p = .0001), and the number of normosmic individuals (p = .0001) at different times (p < .05). The thresholds scores (p = .0001, p = .0001), the identification scores (p = .0001, p = .0001), food‐related odors identification scores (p = .0001, p = .0002), and the number of normomic individuals (p = .001, p = .001) detected on 30th day were significantly higher than on 0th and 1st days; respectively (p < .05). Additionally, the threshold scores (p = .0001), the identification scores (p = .003), food‐related odors identification scores (p = .007), and the number of normosmic individuals (p = .018) detected on day 1 were significantly higher than on day 0 (p < .05).ConclusionThe current study demonstrated that Ramadan fasting enhances the olfactory detection threshold and odor identification scores, significantly improving the identification of food‐related odors. The results may indicate that Ramadan fasting improves olfactory performance.Level of evidenceLevel II.
