Background: Cambodian Americans have high rates of cardiometabolic and psychiatric disorders and disadvantaged social determinants of health (SDOH). These factors can make it challenging to resolve drug therapy problems (DTPs) and improve medication-related outcomes. This manuscript reports planned analyses from a randomized controlled trial in which participants were randomized to one of 3 treatment arms: (1) community health worker (CHW)-delivered lifestyle intervention called Eat, Walk, sleep (EWS), (2) EWS plus pharmacist/CHW-delivered medication therapy management (EWS + MTM), or (3) social services (SS: control).
Objectives: We compared the 3 arms on changes in self-reported medication adherence, barriers, and beliefs. Within the EWS + MTM arm only, we assessed the impact of EWS + MTM on DTP resolution and examined predictors of DTP resolution.
Methods: Cambodian Americans at the age of 35-75 years at high risk of developing diabetes and meeting the criteria for likely depression (N = 188) were randomized (EWS, n = 67; EWS + MTM, n = 63; SS, n = 50; control). For all participants, self-reported surveys were collected at baseline, 12 months, and 15 months. DTPs were assessed on the same schedule but only for participants in the EWS + MTM.
Results: All 3 groups reported a significant decrease in barriers to taking medications. Compared with the other arms, the EWS + MTM arm reported a decrease in forgetting to take medications at 15 months. In the EWS + MTM arm, mean DTPs per patient was 6.57 and 84% of DTPs were resolved. SDOH predictors of DTP resolution included years of education (odds ratio [OR] 0.94, P = 0.016), ability to write English (OR 0.73, P = 0.015), difficulty communicating with provider (OR 1.39, P < 0.001), private insurance (OR 1.99, P = 0.030), disability (OR 0.51, P = 0.008), and years living under Pol Pot (OR 0.66, P = 0.045). Medication barriers at baseline predicted DTP resolution (OR 0.79, P = 0.019) such that each additional barrier was associated with a 21% reduction (1-0.79) in the odds of having a resolution.
Conclusion: CHWs can reduce medications barriers and help pharmacists reduce DTPs in disadvantaged populations.

Background And Purpose: The aim of this study was to assess the intracerebral hemorrhage (ICH) burden in 204 countries and territories worldwide from 1990 to 2021, disaggregated by sex, age, and sociodemographic index (SDI) at the global, regional, and country levels.
Methods: Data from the 2021 Global Burden of Disease Study (GBD) were used to calculate age-standardized prevalence (ASPR), incidence (ASIR), death (ASDR), and disability-adjusted life year (DALY) rates for ICH. The estimated annual percentage change (EAPC) was used to assess time patterns.
Multifunctional nanocellulose hybrid films: From packaging to photovoltaics.

This study aimed to develop eco-friendly multifunctional nanocellulose (NC) hybrid films with tailored properties for versatile applications including packaging and photovoltaics. Hybrid films composed by cellulose nanocrystals (CNC) and carboxymethylated cellulose nanofibrils (CNF) were produced at various mass ratio (CNC - 100:0 to 0:100). Montmorillonite clay (MTM) was incorporated (50 % by mass) into the CNC:CNF films.

The effects of guanidinium hydrochloride (GdmCl) on two intrinsically disordered proteins (IDPs) are investigated using simulations of the self-organized polymer-IDP (SOP-IDP) model. The impact of GdmCl is taken into account using the molecular transfer model (MTM). We show that due to the dramatic reduction in the stiffness of the highly charged Prothymosin-α (ProTα) with increasing concentration of GdmCl ([GdmCl]), the radius of gyration () decreases sharply until about 1.

Materials with red room-temperature phosphorescence (RTP) derived from sustainable sources are crucial but rarely reported. Here, we produced red RTP materials from lignin. Lignin was covalently modified with Upy (1-(6-isocyanatohexyl)-3-(6-methyl-4-oxo-1,4-dihydropyrimidin-2-yl) urea) to obtain Lig-Upy.
