Alternative to sun exposure (the primary\u0000source of vitamin D), vitamin D can also be obtained from food (e.g., fish,\u0000eggs, and meat) and supplements. However, vitamin D intake among Aboriginal and\u0000Torres Strait Islander peoples is currently unknown. We aimed to provide the\u0000first quantification of vitamin D intake using nationally representative data\u0000from Aboriginal and Torres Strait Islander peoples. Methods: We used food\u0000consumption data collected in the 2012-2013 National Aboriginal and Torres\u0000Strait Islander Nutrition and Physical Activity Survey (n = 4,109) and vitamin\u0000D food composition data to quantify mean absolute vitamin D intake by sex, age\u0000group, and remoteness of location. Differences in mean vitamin D intake between\u0000sexes and between remoteness of location were assessed using the 95% confidence\u0000interval (95% CI). Results: The mean (standard deviation (SD)) vitamin D intake\u0000among Aboriginal and Torres Strait Islander peoples was 2.9 (3.0) {mu}g/day.\u0000Males had a statistically significantly higher mean (SD) [95% CI] vitamin D\u0000intake (3.2 (3.1) [3.0-3.4] {mu}g/day) than females (2.6 (2.7) [2.4-2.7]\u0000{mu}g/day).

Existing ways of determining chronotypes, such as Dim Light\u0000Melatonin Onset (DLMO) or the Morningness-Eveningness Questionnaire (MEQ), are\u0000limited by being discrete in time and time-intensive to update, rarely\u0000capturing real-world variability over time. Chronotyping users based on living\u0000schedules, as in daily planner apps, might augment existing methods by\u0000assessing chronotype and social jet lag continuously and at scale. Developing\u0000this functionality would require a novel tool to translate between digital\u0000schedules and chronotypes. Here we use a supervised binary classifier to assess\u0000the feasibility of this approach. Methods: In this study, 1,460 registered\u0000users from the Owaves app opted in to filled out the MEQ survey. Of those, 142\u0000met the eligibility criteria for data analysis. We used multimodal app data to\u0000assess the classification of individuals identified as morning and evening\u0000types from MEQ data, basing the classifier on app time series data. This\u0000includes daily timing for 8 main lifestyle activity categories (exercise,\u0000sleep, social interactions, meal times, relaxation, work, play, and\u0000miscellaneous) as defined in the app. Results: The novel chronotyping tool was\u0000able to predict the morningness and eveningness of its users with an ROC AUC of\u00000.70. Conclusion: Our findings support the feasibility of chronotype\u0000classification from multimodal, real-world app data. We highlight challenges to\u0000applying binary labels to complex, multimodal behaviors.

This study determined the effects of\u0000cement dust exposure on the weight and blood glucose levels of people residing\u0000or working around a cement company in Sokoto, Nigeria. Demographic information\u0000was obtained using questionnaires from 72 participants, which included age,\u0000gender, educational level, exposure hours, occupation, and lifestyle. The blood\u0000glucose levels and body mass index (BMI) were measured using a Fine Test\u0000glucometer and a mechanical scale, respectively. The results showed that most\u0000of the people living or working around the cement company were middle-aged men\u0000(31-40; 42.06%) with a primary (33.33%) or secondary (45.83%) school education.\u0000It showed that 30 (41.69%) of the participants were overweight while 5 (6.94%)\u0000were obese.

However, concerns are growing regarding the potential\u0000toxicities of induced ripening, emphasizing the need for scientific\u0000investigation. Samples of artificially and naturally ripened mangoes were\u0000analyzed for proximate composition using standard protocols. Cytogenotoxicity\u0000was then assessed using the Allium cepa L. toxicity test. Twenty (20)A. cepa\u0000(onion) bulbs were used, with 5 ripened naturally, 5 with wood ash, 5 with\u0000herbaceous ash, and 5 with rice chips, all grown over tap water for five days.\u0000The root tips of the bulbs were assayed and examined for chromosomal\u0000aberrations.
