Background: Meat consumption is increasingly becoming a larger part of diets worldwide. However, the bioaccumulation of toxic metals from anthropogenic pollution is a potential health risk to human health.
Objective: To measure the daily intake of zinc, chromium, and nickel from cow meat consumption and assess the possible health risks in an urban population in Nigeria.
Methods: Dried meat samples were digested with 3 : 2HNO3 : HClO4 v/v. Zinc, chromium, and nickel concentrations were determined with atomic absorption spectrophotometer. Daily intakes of meat were obtained using a food frequency questionnaire (FFQ).
Results: The estimated daily intakes (EDI) (μg/person/day) ranges were: zinc (10 496-13 459), chromium (310·90-393·73), and nickel (26·72-34·87). Estimated daily intake for zinc was 15-30% of provisional maximum tolerable daily intake (PMTDI) and for nickel it was 8-15% of tolerable daily intake (TDI).
Conclusion: Chromium intakes were above recommended daily intake (RDI). Target hazard quotient (THQ) for nickel and zinc were within WHO/FAO limit. There was no evidence of possible health risk to consumers with regard to zinc and nickel. However, chromium intake should be of utmost concern, while disposal of tanning waste should be checked.

The effects of salt reduction and adequate nutrition intake among older adults with physical frailty remain controversial. Therefore, the present study investigated whether the association between daily salt intake and blood pressure among community-dwelling older adults, including the very old people, based on their physical frailty status. This cross-sectional study used data from the SONIC study, a cohort study on older adults, collected between 2010 and 2012.

Background: Young adults (YAs) are underrepresented in behavioral health and weight loss interventions and express interest in flexible, highly tailored programs. Mobile interventions are a lower-burden, scalable approach to providing behavioral support. Just-in-time-adaptive interventions (JITAI) promise to deliver the "right" support at the "right" time using real-time data from smartphones and sensors.

Thiourea vulcanization accelerators (TVAs) have been detected in various household dust samples, indicating their widespread human exposure. Until now, the occurrence of TVAs in human urine, a suitable matrix for assessing human exposure, has remained unknown. The present study comprehensively examined eight kinds of TVAs in urine samples (n = 277) from participants living in Taizhou, China.

Background: Shared decision-making between clinicians and service users is crucial in mental health care. One significant barrier to achieving this goal is the lack of user-centered services. Integrating digital tools into mental health services holds promise for addressing some of these challenges.
