]. ROS began in 1994 and consists of nuns, priests, and brothers from across the USA, MAP began in 1997 and consists of community-dwelling older adults from the greater Chicago metropolitan area, and MARS began in 2004 and consists of community-dwelling older African Americans free of dementia. All studies were approved by the Institutional Review Board at Rush University Medical Center.
4 µl of Master mix was mixed with 4 µl of the prepared serum and the entire volume was loaded into the digital PCR plate and run on the Constellation digital PCR system using the following thermocycling conditions: [98 C for 120 s, 40 cycles of {98 C for 10 s, 60 C for 30 s}, 45 C for 30 s].: Amplification thresholds were applied using the Constellation software .

Associations between smoking and vaping prevalence, product use characteristics, and mental health diagnoses in Great Britain: a population survey - BMC MedicineBackground Rates of diseases and death from tobacco smoking are substantially higher among those with a mental health condition (MHC). Vaping can help some people quit smoking, but little is known about vaping among people with MHCs or psychological distress. We assessed the prevalence and characteristics (heaviness, product type) of smoking and/or vaping among those with and without a history of single or multiple MHC diagnoses and with no, moderate or serious psychological distress. Methods Data from 27,437 adults in Great Britain surveyed between 2020 and 2022. Multinomial regressions analysed associations between smoking, vaping and dual use prevalence, smoking/vaping characteristics and (a) history of a single or multiple MHC and (b) moderate or serious psychological distress, adjusted for age, gender, and socioeconomic status. Results Compared with people who had never smoked, those who currently smoked were more likely to report a history of a single (12.5% vs 15.0%, AOR=1.62, 95% CI=1.46–1.81, p|.001) or multiple MHCs (12.8% vs 29.3%, AOR=2.51, 95% CI=2.28–2.75, p|.001). Compared with non-vapers, current vapers were more likely to report a history of a single (13.5% vs 15.5%, AOR=1.28, 95% CI=1.11–1.48, p|.001) or multiple MHCs (15.5% vs 33.4%, AOR=1.66, 95% CI=1.47–1.87, p|.001). Dual users were more likely to report a history of multiple MHCs (36.8%), but not a single MHC than exclusive smokers (27.2%) and exclusive vapers (30.4%) (all p|.05). Similar associations were reported for those with moderate or serious psychological distress. Smoking roll-your-own cigarettes and smoking more heavily, were associated with a history of single or multiple MHCs. There were no associations between vaping characteristics and a history of MHCs. Frequency of vaping, device type and nicotine concentration differed by psychological distress. Conclusions Smoking, vaping and dual use were substantially higher among those with a history of MHC, especially multiple MHC, and ex
