Longitudinal findings of a U.S. preventive evidence-based family intervention tested among youth in Ecuador: Familias Unidas.

Interventions that address adolescent conduct problems are essential for decreasing negative risk behaviors and promoting positive protective factors among youth. Although interventions have been developed and tested in the United States, preventive evidence-based interventions (EBIs) are less available in Latin American countries such as Ecuador. Therefore, the purpose of this study was to evaluate the efficacy of an evidence-based, parent-centered intervention, Familias Unidas, in preventing/reducing conduct problems, across time, among youth in Guayaquil, Ecuador. Ecuadorian youth (ages 12 through 14) and their respective primary caregiver were recruited from two public schools and randomized to either Familias Unidas or Community Practice. A series of latent growth models were run to test for differences between Familias Unidas and Community Practice on conduct disorder symptoms across three timepoints covering 6 months. Ecuadorian mental health professionals were trained to deliver the evidence-based intervention. Findings indicate no direct relationship between condition and average change in conduct problems at 6 months post baseline. However, indirect effects favoring Familias Unidas over Community Practice were found through improvements in family functioning. Findings highlight that Familias Unidas was efficacious in an international setting and indicate the viability of successfully delivering preventive EBIs in Ecuador.

Perceived discrimination and posttraumatic stress disorder among Venezuelan migrants in Colombia and the United States: The moderating effect of gender.

OBJECTIVES: The primary aim of this study was to examine the association between perceived discrimination and posttraumatic stress disorder (PTSD) outcomes among recently arrived Venezuelan parents in Florida and Colombia. The secondary aim was to determine whether, given the existence of an association between perceived discrimination and PTSD, this association may have been moderated by gender or by country of relocation. This is the first study to examine perceived discrimination and PTSD in Venezuelan migrants. METHOD: In October 2017, 647 Venezuelan migrant parents (62% female, average age 33) participated in an online survey in the United States (primarily Florida) and Colombia (Bogotá). The survey was cross-sectional and assessed mental health outcomes, perceived discrimination, and participant demographics. RESULTS: There was a significant positive association between discrimination and PTSD outcomes when controlling for age, college completion, marital status, and recency of arrival (ß = .25, p < .001). Further, this relationship was moderated by gender, with the relationships of discrimination with PTSD symptom severity (ß = .26, p < .001) and likelihood of a positive PTSD screen (OR = 1.07, 95% confidence interval [1.04, 1.09], p < .001) both reaching significance for women but not for men. CONCLUSIONS: Perceived discrimination is an important factor when considering mental health outcomes among Venezuelans in the United States and in Colombia. Further, our findings suggest the presence of gender differences in the relationship between discrimination and PTSD. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Assessing Community Readiness for Preventing Youth Substance Use in Colombia: A Latent Profile Analysis.

The growing use of evidence-based preventive interventions for youth substance use in Latin American countries has prompted governments, researchers, and practitioners to ask if communities are ready for implementing these interventions, especially in light of the elevated costs and long-term commitment necessary for successful implementation. This study explores the construct validity of a measure of community readiness for prevention, using confirmatory factor and latent profile analyses of 7 measures theorized to be indicators of community readiness for implementing preventive interventions for youth substance use. Data were obtained from 211 community leaders in 16 communities in Colombia. Results indicate that community readiness can be represented as a unidimensional construct with multiple profiles of varying levels of readiness. Findings suggest community readiness can be measured adequately as a latent construct and that its indicators can be used diagnostically to assess areas where readiness could be improved for better implementation of evidence-based preventive interventions.

Understanding of for whom, under what conditions and how the compulsory licensing of pharmaceuticals works in Brazil and Thailand: A realist synthesis.

When pharmaceuticals are not fully available mainly due to the high cost of medicines, a government can issue compulsory licensing (CL). It is well documented that Brazil and Thailand have notably attempted CL. A realist review was undertaken to understand the identical social interventions in comparative settings, and to draw practical implications for attempting CL relevant for middle-income countries in the era of high-cost medicines. CL is not only a politically well-devised measure to achieve universal health coverage, but also a tentative commitment, which is determined both at the country level and at the global level. At the country level, political will, with catalytic roles of civil activism, is important in order to guarantee the right to health. Through this will, the governments can achieve universal health coverage. In addition, electoral systems, political leaders, and a constitution are necessary to attempt CL. In addition, CL should operate along with other policy instruments, including a comprehensive essential medicines list, CL-friendly phrasing in patent law, and a competent pharmaceutical industry. At the global level, the balance of power between the WTO regime and the global justice movement is critical. This provides global-level context that can either encourage or prevent CL.

Relationship of rheumatoid arthritis and coronary artery disease in the Korean population: a nationwide cross-sectional study

Abstract Background: Rheumatoid arthritis (RA) is known to be associated with coronary artery diseases (CAD). Previous studies of the association between RA and CAD were reported mainly in non-Asian groups. We aimed to examine the prevalence of RA and the relationship between RA and CAD in South Korea. Methods: We conducted a nationwide cross-sectional study by using the Korea National Health and Nutrition Examination Survey, which collected data for four years between 2008 and 2012. A total of 25,828 eligible participants were included. To balance the distribution of baseline characteristics, we used propensity scorematching. A multivariable logistic regression model was employed and we calculated the odds ratios (ORs) and 95% confidence intervals (CI) for the odds of the participants with RA on CAD prevalence. Results: The prevalence of RA in Korea from 2008 to 2012 was 0.6% and RA was predominant among elderly women. The prevalence of CAD in patients with RA was significantly higher than in general population. After propensity score-matching to balance the confounding factors, RA was significantly associated with CAD (OR 2.97, 95% CI 1.15-7.68, P= 0.02). Conclusions: The prevalence of RA in South Korea was comparable to the worldwide data, and the presence of CAD in RA patients was more than two-fold.

A new feruloyl glyceride from the roots of Asian rice (Oryza sativa)

Abstract Oryza sativa L., Poaceae, is the most important staple food in the world and provides food for more than half of the world's population. The roots of O. sativa have been used as a traditional medicine in Korea. As part of our continuing efforts to explore structurally new compounds from Korean natural resources, two feruloyl glycerides, 2-O-(E)-feruloyl glyceride (1) and 2-O-(Z)-feruloyl glyceride (2), which is a new compound, together with one known flavonoid, 8-hydroxyacacetin (3), were isolated from the ethanolic extract of the roots of O. sativa using an LC/MS-guided isolation method. The chemical structure of compound 2 was elucidated based on comprehensive 1D and 2D NMR spectroscopic experiments and HR-ESIMS. This study represents the first report of feruloyl glycerides (1-2) identified in O. sativa. In addition, the identification of compound 3 is reported from Asian rice (O. sativa) for the first time. The cytotoxic activities of the isolates 1-3 were evaluated by determining their inhibitory effects on A2780 human ovarian carcinoma cells.

Short-Term Effects on Family Communication and Adolescent Conduct Problems: Familias Unidas in Ecuador.

Familias Unidas, a Hispanic/Latino-specific, parent-centered intervention, found to be efficacious in improving family functioning and reducing externalizing behaviors among youth in the USA, was recently adapted and tested for use in Ecuador. This study examined the short-term efficacy of Familias Unidas in Ecuador on parent-adolescent communication, parental monitoring of peers, and youth conduct problems. Two hundred thirty-nine youths (ages 12-14 years) and their primary care givers were randomized to either Familias Unidas or Community Practice and assessed pre- and post-intervention. There was a significant difference between Familias Unidas and Community Practice in conduct problems at 3 months (standardized ß = -.101, p = .001, effect size = .262). A significant indirect intervention effect was also detected, indicating that Familias Unidas predicted conduct problems at 3 months through parent-adolescent communication at 3 months (standardized ß = -.036, p = .016, CI 95% [-.066, -.007], effect size = .265). Familias Unidas was efficacious in reducing conduct problems through improved parent-adolescent communication, relative to Community Practice. Future assessments will determine whether Familias Unidas also has an impact on substance use and sexual risk behaviors at later time points, as demonstrated in past Familias Unidas trials. The short-term effects of the intervention, family engagement, and facilitator skill in the Ecuadorian adaptation of Familias Unidas are promising. This study implies that an intervention developed for Hispanics/Latinos in the USA and culturally adapted and implemented for use by Hispanics/Latinos in a Latin American country can be efficacious in improving family functioning and reducing youth conduct problems.

Chronic active EBV infection: the experience of the Samsung Medical Center in South Korea / Infección crónica activa por virus de Epstein-Barr: experiencia del Centro Médico Samsung en Corea del Sur

Abstract Background: Chronic active EBV infection (CAEBV) of T-cell or NK-cell type is an EBV+ polyclonal, oligoclonal or often monoclonal lymphoproliferative disorder (LPD) recognized as representing the spectrum of EBV-associated T-cell and NK-cell LPD with different clinical presentations; one systemic and two cutaneous disorders including hydroa vacciniforme-like T-cell LPD and mosquito bite hypersensitivity. The systemic form of the disease is characterized by fever, persistent hepatitis, hepatosplenomegaly and lymphadenopathy, which shows varying degrees of clinical severity depending on the immune response of the host and the EBV viral load. Case reports: We described the clinicopathological findings of two children with CAEBV with a brief review of the literature. Conclusions: Recognition of the disease is important for adequate management of the patient. EBV analysis should be included in the principal diagnostic tests for febrile children.

Relationships among the Y balance test, Berg Balance Scale, and lower limb strength in middle-aged and older females.

BACKGROUND: Older females have less dynamic postural control and muscle strength than do middle-aged females. Aging-related strength losses may limit balancing performance. OBJECTIVE: The purpose of this study was to investigate the ability of the Y Balance Test (YBT) and lower limb strength to discriminate between females in 2 age groups, the relationship between YBT distance and the Berg Balance Scale (BBS), and the degree to which performance on YBT distance is related to lower limb strength in middle-aged and older females. METHOD: The 40 healthy, independently active females were divided into 2 groups: older and middle-aged. The participants underwent measurements of YBT distance using the YBT, maximal muscular strength of the lower limbs using a handheld dynamometer, and the BBS. RESULTS: The YBT distance in 3 directions and lower limb muscle strength for both lower limbs were significantly lower in the older adults than in the middle-aged group. A moderate correlation but insignificant correlation was found between the YBT composite distance and the BBS score. In the older females, YBT distance was significantly positively correlated with strength of the knee flexor and hip abductor. In the middle-aged group, YBT distance was significantly positively correlated with strength of the knee flexor and hip extensor. CONCLUSIONS: Performance on the YBT was influenced by the strength of lower limb. We suggested that YBT can be used to alternative as a measurement of dynamic balance. Proper training programs for older people could include not only strengthening exercises but also YBT performance to improve balance.

Differential expression of immunologic proteins in gingiva after socket preservation in mini pigs.

UNLABELLED: During healing following tooth extraction, inflammation and the immune response within the extraction socket are related to bone resorption. OBJECTIVE: We sought to identify how the alloplastic material used for socket preservation affects the immune responses and osteoclastic activity within extraction sockets. MATERIAL AND METHODS: Using a porcine model, we extracted teeth and grafted biphasic calcium phosphate into the extraction sockets. We then performed a peptide analysis with samples of gingival tissue from adjacent to the sockets and compared the extraction only (EO) and extraction with socket preservation (SP) groups. We also used real-time polymerase chain reaction (PCR) to evaluate the expression level of immunoglobulins, chemokines and other factors related to osteoclastogenesis. Differences between the groups were analyzed for statistical significance using paired t tests. RESULTS: Levels of IgM, IgG and IGL expression were higher in the EO group than in the SP group 1 week post-extraction, as were the levels of CCL3, CCL5, CXCL2, IFN-γ and TNF-α expression (p < 0.05). In addition, receptor activator of nuclear factor kappa-B ligand (RANKL) was also significantly upregulated in the EO group (p < 0.05), as were IL-1ß, IL-6 and IL-8 (p < 0.05). CONCLUSIONS: These results suggest that the beneficial effect of socket preservation can be explained by suppression of immune responses and inflammation.

The repetitive component of the A genome of peanut (Arachis hypogaea) and its role in remodelling intergenic sequence space since its evolutionary divergence from the B genome.

BACKGROUND AND AIMS: Peanut (Arachis hypogaea) is an allotetraploid (AABB-type genome) of recent origin, with a genome of about 2·8 Gb and a high repetitive content. This study reports an analysis of the repetitive component of the peanut A genome using bacterial artificial chromosome (BAC) clones from A. duranensis, the most probable A genome donor, and the probable consequences of the activity of these elements since the divergence of the peanut A and B genomes. METHODS: The repetitive content of the A genome was analysed by using A. duranensis BAC clones as probes for fluorescence in situ hybridization (BAC-FISH), and by sequencing and characterization of 12 genomic regions. For the analysis of the evolutionary dynamics, two A genome regions are compared with their B genome homeologues. KEY RESULTS: BAC-FISH using 27 A. duranensis BAC clones as probes gave dispersed and repetitive DNA characteristic signals, predominantly in interstitial regions of the peanut A chromosomes. The sequences of 14 BAC clones showed complete and truncated copies of ten abundant long terminal repeat (LTR) retrotransposons, characterized here. Almost all dateable transposition events occurred <3·5 million years ago, the estimated date of the divergence of A and B genomes. The most abundant retrotransposon is Feral, apparently parasitic on the retrotransposon FIDEL, followed by Pipa, also non-autonomous and probably parasitic on a retrotransposon we named Pipoka. The comparison of the A and B genome homeologous regions showed conserved segments of high sequence identity, punctuated by predominantly indel regions without significant similarity. CONCLUSIONS: A substantial proportion of the highly repetitive component of the peanut A genome appears to be accounted for by relatively few LTR retrotransposons and their truncated copies or solo LTRs. The most abundant of the retrotransposons are non-autonomous. The activity of these retrotransposons has been a very significant driver of genome evolution since the evolutionary divergence of the A and B genomes.
