Structural brain correlates of heart rate variability in a healthy young adult population

There are various devices and applications available in the market that can be used to measure heart rates. These are becoming increasingly popular. Amongst these include the Apple watch, the Xiaomi MI Band and using the Thermal Application (T.A.P.) software (used through a Smartphone). In clinical practice and research, usually the E.C.G. Is used to measure the heart rates, (apart from manually counting the beats by palpation). The study will determine the accuracy of using the available devices in the market (previously mentioned), and also determine if they can be used on patients or subjects while sitting and walking, in clinical practice and researches. Method: It will be a comparative observational study. 50 students, selected as per the inclusion and exclusion criteria from Datta Meghe Institute of Medical Sciences will be the subjects of this study. Their heart rates will be monitored with the three devices, and compared with the readings from an E.C.G. It will be done as per Bruce protocol during walking, and in static sitting. The accuracy of the devices will be determined by analyzing the results acquired. The devices are: Apple watch, Xiaomi MI band, and a smart Phone with Thermal Application (T.A.P.) software installed. The successful completion of the study will determine which of the devices show the most accurate heart rate readings, in what positions of a patient (sitting or walking) it would be acceptable to use these devices (in terms of accuracy) in the case where an E.C.G. is not available, or at a time of urgency. The study will also show if it would be appropriate to use these devices in clinical practice and research studies.

Young Adult Population

In the past, epidemiological studies focused on cavitated stages of caries. The arrival of the International Caries Detection and Assessment System (ICDAS) in 2004 allowed for clinical measurements of the initial stages of enamel caries. However, since the introduction, most studies applying the ICDAS still have studied the diseased population. The objective of this cross-sectional observational study was to describe early enamel caries in a large healthy young adult population and determine the relationship with diet and oral hygiene measures. The study population consisted of 268 healthy participants without frank cavitation. The examinations were done visually and radiographically using ICDAS on all tooth surfaces. In total, 8.6% of the surfaces (occlusal > approximal > smooth) had caries, of which 92.0% were confined to enamel (28.5% ICDAS score 1, 54.0% score 2, 8.6% score 3). Thirteen percent of the occlusal and 63% of the approximal caries were found with radiography. Thus, radiography is quintessential for the diagnosis of approximal enamel lesions. We found a positive correlation between enamel caries (ICDAS 1 to 3) and the consumption of mono- and disaccharides and carbohydrates ( r = 0.226 and r = 0.188, respectively, both P < 0.01), as well as a negative correlation with alcohol consumption ( r = −0.202, P < 0.01). There was also a positive correlation between enamel caries and the energy intake from mono- and disaccharides (sugar kJ, r = 0.206, P < 0.01), which was independent of body mass index. Only 11 participants consumed less than 10% of total energy as sugar kJ, which is the recommended percentage of kJ from free sugar by the World Health Organization. No clear correlation was found with oral hygiene. In conclusion, in this healthy young adult population, caries was found in 97.8% of the subjects, mostly initial enamel caries (ICDAS 1 to 2) in the occlusal surface of molars, and was related with dietary factors.
