Prospective pathways to depressive symptoms and disordered eating in adolescence: A 7-year longitudinal cohort study
Eating pathology and depressive symptoms increase during adolescence, yet predictive pathways remain predominantly unexplored, despite their implications for prevention. The present study aimed to identify shared risk factors for eating pathology and depressive symptoms by evaluating an adapted Dual-Pathway Model of disordered eating, which postulated that higher BMI would predict disordered eating and depressive symptoms via pathways between body dissatisfaction, later BMI, depressive symptoms, and visible indicators of puberty (breast development for girls, height for boys). The participants were 8,915 children (49% girls) from the Avon Longitudinal Study of Parents and Children, a population-based cohort study of British children, who were assessed at different intervals between the age of 7 to 14 years. Path analyses revealed that, for girls, childhood BMI exerted indirect effects on disordered eating via body dissatisfaction, depressive symptoms, and more advanced breast development, with indirect pathways identified to depressive symptoms via earlier depressive symptoms and more advanced breast development. For boys, childhood BMI had indirect effects on disordered eating via later BMI and body dissatisfaction, while only earlier depressive symptoms were found to have an independent and direct effect on adolescent depressive symptoms. This study reveals shared and independent risk factors for eating pathology and depressive symptoms in adolescence and suggests targets for preventative interventions, including higher BMI, body dissatisfaction, and depressive symptoms, in addition to advanced breast development, for girls
Emotional Abilities in Children with Oppositional Defiant Disorder (ODD): Impairments in Perspective-Taking and Understanding Mixed Emotions are Associated with High Callous-Unemotional Traits
Most studies of emotion abilities in disruptive children focus on emotion expression recognition. This study compared 74 children aged 4-8 years with ODD to 45 comparison children (33 healthy; 12 with an anxiety disorder) on behaviourally assessed measures of emotion perception, emotion perspective-taking, knowledge of emotions causes and understanding ambivalent emotions and on parent-reported cognitive and affective empathy. Adjusting for child's sex, age and expressive language ODD children showed a paucity in attributing causes to emotions but no other deficits relative to the comparison groups. ODD boys with high levels of callous-unemotional traits (CU) (n = 22) showed deficits relative to low CU ODD boys (n = 25) in emotion perspective-taking and in understanding ambivalent emotions. Low CU ODD boys did not differ from the healthy typically developing boys (n = 12). Impairments in emotion perceptive-taking and understanding mixed emotions in ODD boys are associated with the presence of a high level of CU
"Me, I'm Living It": The Primary Health Care Experiences of Women who use Drugs in Vancouverâs Downtown Eastside: Summary of Findings from the VANDU Women's Clinic Action Research for Empowerment Study
First paragraph: Preventing and reducing the harmful consequences of drug use has been identified as a key priority in Canada at all levels of government. Initiatives to reduce barriers to care for marginalized women who use drugs are currently underway. However, despite the significant national and international attention paid to the health and social conditions of women in Vancouver's Downtown Eastside (DTES), women who use drugs in this community report persistent health inequities and barriers to accessing a wide range of services, including primary health care, harm reduction services, mental health care, and addictions treatment. These inequities and barriers to care result from a complex interplay of social, political and economic factors. In order to provide effective, empowering, compassionate, and respectful care for women who use drugs it is crucial to understand how these factors influence health and well-being
The Integration of the Program Evaluation Standards into an Evaluation Toolkit for a Transformative Model of Care for Mental Health Service Delivery
Background: Stepped Care 2.0 (SC2.0) is a transformative model of mental health service delivery. This model was created by Stepped Care Solutions (SCS), a not-for-profit consultancy that collaborates with governments, public service organizations, and other institutions that wish to redesign their mental health and addictions systems of care. The SC2.0 model is based on 10 foundational principles and 9 core components that can be flexibly adapted to an organizationâs or communityâs needs. The model supports groups to reorganize and deliver mental health care in an evidence-informed, person-centric way. SCS partnered with evaluators from the Centre for Health Evaluation and Outcome Sciences (CHĂOS) to create a toolkit that provides evaluation guidance. The toolkit includes a theory of change, guidance on selecting evaluation questions and designs, and an evaluation matrix including suggested process and outcome metrics, all of which can be tailored to each unique implementation of the SC2.0 model. The objective of this resource is to support organizations and communities to conduct high-quality evaluations for the purpose of continuous improvement (a core component of the model of care) and to assess the modelâs impact.
Purpose: The purpose of this paper is to discuss the integration of the program evaluation standards (PES) into an evaluation toolkit for SC2.0.
Setting: In this paper, we describe the toolkit development, focusing on how the PES were embedded in the process and tools. We explore how the integration of the PES into the toolkit supports evaluators to enhance the quality of their evaluation planning, execution, and meta-evaluation.

Sustained virological response after treatment with direct antiviral agents in individuals with HIV and hepatitis C co-infection.
INTRODUCTION
Randomized trials and observational studies have consistently reported rates of sustained virological response (SVR), equivalent to hepatitis C virus (HCV) cure, as high as 95% following treatment with direct-acting antiviral (DAA) treatment in individuals with HIV and HCV co-infection. However, large studies assessing whether SVR rates differ according to demographic and clinical strata are lacking. Additionally, the SVR rates reported in the literature were typically computed in non-random samples of individuals with available post-DAA HCV-RNA measures. Here, we aimed to estimate the probability of SVR after DAA treatment initiation in persons with HIV and HCV co-infection overall and by demographic and clinical characteristics with and without adjustment for missing HCV-RNA testing.
METHODS
We included adults with HIV-HCV co-infection who received DAA treatment between 2014 and 2020 in HepCAUSAL, an international collaboration of cohorts from Europe and North America. We estimated the proportions of DAA recipients who had documented SVR (defined as an undetectable HCV-RNA at least 12 weeks after the end of DAA treatment) overall and by strata defined by age, sex, presence of cirrhosis, calendar period, mode of HIV acquisition, CD4 cell count and HCV genotype at DAA treatment. We then compared these rates with those obtained using the parametric g-formula to impute SVR status for individuals with no SVR assessment.
RESULTS AND DISCUSSION
A total of 4527 individuals who initiated DAA treatment (88% males, median [IQR] age 56 [50, 62] years) were included. Of the total of 642 (14%) individuals had no HCV-RNA test on or after 12 weeks after the end of treatment. The overall observed and g-formula imputed SVR rates were 93% (95% CI 93, 94) and 94% (95% CI 92, 95), respectively. SVR estimates were similarly high across all strata. A substantial proportion of individuals who received DAA treatment were never assessed for SVR post-DAA and strategies for more systematic routine HCV-RNA testing should be considered.
CONCLUSIONS
Our estimates with and without adjustment for missing HCV-RNA testing indicate SVR rates of approximately 95%, like those reported in clinical trials
17-a-estradiol late in life extends lifespan in aging UM-HET3 male mice; nicotinamide riboside and three other drugs do not affect lifespan in either sex.
In genetically heterogeneous mice produced by the CByB6F1 x C3D2F1 cross, the non-feminizing estrogen, 17-α-estradiol (17aE2), extended median male lifespan by 19% (p \u3c 0.0001, log-rank test) and 11% (p = 0.007) when fed at 14.4 ppm starting at 16 and 20 months, respectively. 90th percentile lifespans were extended 7% (p = 0.004, Wang-Allison test) and 5% (p = 0.17). Body weights were reduced about 20% after starting the 17aE2 diets. Four other interventions were tested in males and females: nicotinamide riboside, candesartan cilexetil, geranylgeranylacetone, and MIF098. Despite some data suggesting that nicotinamide riboside would be effective, neither it nor the other three increased lifespans significantly at the doses tested. The 17aE2 results confirm and extend our original reports, with very similar results when started at 16 months compared with mice started at 10 months of age in a prior study. The consistently large lifespan benefit in males, even when treatment is started late in life, may provide information on sex-specific aspects of aging
Vascular endothelial growth factor-A165b is protective and restores endothelial glycocalyx in diabetic nephropathy
Diabetic nephropathy is the leading cause of ESRD in high-income countries and a growing problem across the world. Vascular endothelial growth factor-A (VEGF-A) is thought to be a critical mediator of vascular dysfunction in diabetic nephropathy, yet VEGF-A knockout and overexpression of angiogenic VEGF-A isoforms each worsen diabetic nephropathy. We examined the vasculoprotective effects of the VEGF-A isoform VEGF-A165b in diabetic nephropathy. Renal expression of VEGF-A165b mRNA was upregulated in diabetic individuals with well preserved kidney function, but not in those with progressive disease. Reproducing this VEGF-A165b upregulation in mouse podocytes in vivo prevented functional and histologic abnormalities in diabetic nephropathy. Biweekly systemic injections of recombinant human VEGF-A165b reduced features of diabetic nephropathy when initiated during early or advanced nephropathy in a model of type 1 diabetes and when initiated during early nephropathy in a model of type 2 diabetes. VEGF-A165b normalized glomerular permeability through phosphorylation of VEGF receptor 2 in glomerular endothelial cells, and reversed diabetes-induced damage to the glomerular endothelial glycocalyx. VEGF-A165b also improved the permeability function of isolated diabetic human glomeruli. These results show that VEGF-A165b acts via the endothelium to protect blood vessels and ameliorate diabetic nephropathy
