Associations between Otitis media, taste sensitivity and adiposity: Two studies across childhood

The influence of NaCl on the dynamic perception of the pungency sensation elicited by Sichuan pepper oleoresins

A cross-modal interaction may exist between the perception of saltiness and the pungency elicited by Sichuan pepper oleoresin (Spo). Thirty-one hypersensitive panelists were selected to participate in this study. Spo solutions dissolved in different NaCl concentrations, ranging from 1.25 g/L to 167.9 g/L, were used as the test samples. The rated difference from control, the generalized labeled magnitude scale (gLMS), and the time-intensity (TI) method were used to determine the detection threshold (DT), the recognition threshold (RT), the intensity, and the dynamic perception of pungent sensation. The results revealed that the pungency thresholds increased significantly (p < 0.01) in the solution with a high NaCl (167.9 g/L) concentration. Furthermore, high NaCl solutions suppressed the pungency intensity at all Spo concentrations except for 0.02 g Spo/L in water (p < 0.05). The TI and principal component analysis (PCA) results showed that an increase in the Spo concentration prolonged the duration of the pungency sensation. However, the maximum intensity, the time to reach maximum intensity, the decay time of perception, and the end time of perception of the Spo solutions ranging from 2.13 g/L to 4.69 g/L were significantly reduced at medium (42.95 g/L) and high NaCl concentrations. Since the salty and pungency sensations exhibited by NaCl and Spo are common flavor combinations in food products and dishes, studying the influence of saltiness on the dynamic perception of pungent sensation not only aids the development of oral cleaners during pungency evaluation but also presents significant theoretical and practical value in creating pungent food and cuisine based on consumer preferences.

Otitis Media and Obesity-An Unusual Relationship in Children

Otitis media (OM) represents a public health matter, being the main cause of preventable hearing loss in pediatric patients. Besides well-established risk factors for developing OM, such as craniofacial abnormalities, prematurity, low birth weight, or tobacco exposure, there is evidence that obesity could be associated with a high incidence of OM. Our aim is to perform a literature review on the state of current published research on the relationship between OM and obesity and to discuss the interconnectivity between these two entities. We conducted an electronic search in PubMed and EMBASE databases. Out of 176 references, 15 articles were included in our study. Our findings suggest that obesity and overweight might be risk factors for developing OM, and vice versa. The main mechanisms for developing OM in obese patients include alteration in cytokine profile, increased gastroesophageal reflux, and/or fat accumulation. Conversely, ear infections exposure might increase the risk of obesity, mostly by taste changes through middle ear cavity inflammation.
