Previous research has shown a robust association between different childhood and adolescent vulnerabilities and youth offending. However, these investigations have primarily focused on youths from high-income Western countries. Consequently, the generalizability of these findings to better inform global justice policies remains uncertain. This study aimed to address this gap by examining the relationship between individual, familial, and contextual vulnerabilities and criminal versatility during young adulthood, accounting for sociodemographic factors and cross-national differences. Data were derived from a diverse sample of 4,182 young adults (67% female; mean age = 18.96; SD  = 0.81) residing in 10 countries across 5 continents who participated in the International Study of Pro/Antisocial Behavior in Young Adults . The Psychosocial and Family Vulnerability Questionnaire and the Adverse Childhood Experiences questionnaire were used to assess social and family adversity, and past-year criminal diversity was measured with the Criminal Variety Index. Results indicate that child maltreatment, substance abuse, and delinquent peers are global risk factors for criminal variety. Moreover, they are independent across males and females and among youths living in countries that are ranked differently on the Human Development Index (HDI). In addition, some childhood vulnerabilities showed different predictive ability across sexes (e.g., school failure), and across countries ranked differently on the HDI (e.g., family dysfunction). These findings suggest that certain childhood factors contribute to criminal behavior through transcultural mechanisms. Moreover, they highlight the importance of developing evidence-based policies that focus on transcultural risk factors to globally prevent criminal behavior., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interests with respect to the authorship and/or publication of this article.

Cardiovascular complications represent a significant health concern for individuals with diabetes mellitus. The relationship between diabetes and cardiovascular diseases is complex and multifaceted, involving a variety of pathophysiological mechanisms. This study aimed to investigate the potential role of the cardiothoracic ratio as a prognostic tool for cardiovascular disorders in patients with diabetes. A retrospective case-control study of 530 adult patients referred to a tertiary care hospital in Saudi Arabia was conducted. Medical records, including chest X-rays, were analyzed to determine the cardiothoracic ratio. Patients diagnosed with diabetes who experienced cardiac disorders had significantly higher cardiothoracic ratios compared to patients with diabetes alone and controls. HbA1c was significantly elevated among patients with diabetes and cardiovascular disorders (mean = 71.5 ± 25.43 mmol/mol) compared to the other patients. There was a significant positive correlation between the duration of diabetes and the cardiothoracic ratio (r = 0.64, P < 0.001). Furthermore, the cardiothoracic ratio above 0.51 was a good discriminator of cardiovascular disorders in patients with diabetes, with an area under the curve of 0.737, sensitivity of 97.1%, and specificity of 87.2%. This study provided comprehensive evidence supporting the association between cardiothoracic ratio and subsequent cardiovascular adverse outcomes in patients with diabetes. We recommend adopting the cardiothoracic ratio as a valuable prognostic tool for risk stratification among people with diabetes., Competing Interests: The authors declare no conflict of interest., (© 2024 The Author(s).)

Intracardiac lymphomas are exceedingly rare accounting for only 1% of all primary cardiac tumours. Historically, due to their insidious development and non-specific clinical presentation, the diagnosis has been challenging with most cases being confirmed on post-mortem examination. Our case report details the experience of a previously fit and active woman in her 60s who presented with gradual onset exertional dyspnoea. Through a series of multimodal imaging tools (including echocardiogram, cardiac MRI, CT and positron emission tomography-CT) and biopsy, we confirmed the diagnosis of intracardiac diffuse large B-cell lymphoma. Our patient was managed with chemotherapy and went on to demonstrate excellent radiological response with near-complete resolution of the intracardiac mass. Subjectively, our patient reported significant improvement in exercise tolerance within weeks of commencing treatment., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Aim: To explore if novel non-invasive diagnostic technologies identify early small nerve fibre and retinal neurovascular pathology in prediabetes., Methods: Participants with normoglycaemia, prediabetes or type 2 diabetes underwent an exploratory cross-sectional analysis with optical coherence tomography angiography (OCT-A), handheld electroretinography (ERG), corneal confocal microscopy (CCM) and evaluation of electrochemical skin conductance (ESC)., Results: Seventy-five participants with normoglycaemia (n = 20), prediabetes (n = 29) and type 2 diabetes (n = 26) were studied. Compared with normoglycaemia, mean peak ERG amplitudes of retinal responses at low (16-Td·s: 4.05 μV, 95% confidence interval [95% CI] 0.96-7.13) and high (32-Td·s: 5·20 μV, 95% CI 1.54-8.86) retinal illuminance were lower in prediabetes, as were OCT-A parafoveal vessel densities in superficial (0.051 pixels/mm 2 , 95% CI 0.005-0.095) and deep (0.048 pixels/mm 2 , 95% CI 0.003-0.093) retinal layers. There were no differences in CCM or ESC measurements between these two groups. Correlations between HbA 1c and peak ERG amplitude at 32-Td·s (r = -0.256, p = 0.028), implicit time at 32-Td·s (r = 0.422, p < 0.001) and 16-Td·s (r = 0.327, p = 0.005), OCT parafoveal vessel density in the superficial (r = -0.238, p = 0.049) and deep (r = -0.3, p = 0.017) retinal layers, corneal nerve fibre length (CNFL) (r = -0.293, p = 0.017), and ESC-hands (r = -0.244, p = 0.035) were observed. HOMA-IR was a predictor of CNFD (β = -0.94, 95% CI -1.66 to -0.21, p = 0.012) and CNBD (β = -5.02, 95% CI -10.01 to -0.05, p = 0.048)., Conclusions: The glucose threshold for the diagnosis of diabetes is based on emergent retinopathy on fundus examination. We show that both abnormal retinal neurovascular structure (OCT-A) and function (ERG) may precede retinopathy in prediabetes, which require confirmation in larger, adequately powered studies., (© 2022 The Authors.

Background: Adverse Childhood Experiences (ACEs) have been associated with a greater risk of later criminal offending. However, existing research in this area has been primarily conducted in Western developed countries and cross-cultural studies are rare., Objectives: This study examined the relationship between ACEs and criminal behaviors in young adults living in 10 countries located across five continents, after accounting for sex, age, and cross-national differences., Participants and Setting: In total, 3797 young adults aged between 18 and 20 years (M = 18.97; DP = 0.81) were assessed locally in community settings within the 10 countries., Method: The ACE Questionnaire was used to assess maltreatment and household dysfunction during childhood and a subset of questions derived from the Deviant Behavior Variety Scale (DBVS) was used to determine past-year criminal variety pertaining to 10 acts considered crime across participating countries., Results: Physical and sexual abuse, physical neglect, and household substance abuse were related to criminal variety, globally, and independently across sexes and countries ranked differently in the United Nations Human Development Index (HDI). In addition, three out of five experiences of household dysfunction were related to criminal variety, but subsequent analyses indicate that some forms of household dysfunction only hold statistical significance among males or females, or in countries ranking lower in the HDI., Conclusions: This research strengthens the finding that there are cross-cultural mechanisms perpetuating the cycle of violence. It also indicates that forms of household dysfunction have an impact on criminal behavior that is shaped by gender and the country's levels of social well-being., (Copyright © 2022 Elsevier Ltd.

Aims/hypothesis: This study explored the impact of ethnicity on time-to-clinic, time-to-treatment and rates of vision loss in people referred to hospital with diabetic eye disease., Methods: A survival analysis was performed on all referrals from an inner-city diabetic eye screening programme to a tertiary hospital eye service between 1 October 2013 and 31 December 2017. Exclusion criteria were failure to attend hospital, distance visual acuity in both eyes too low to quantify with the Early Treatment Diabetic Retinopathy Study (ETDRS) letter chart and treatment received prior to referral. Demographic and screening grade data were collected at the point of referral. Small-area statistics and census data were used to calculate indices of multiple deprivation. The main outcome measures were time taken from the date of referral for an individual to achieve the following: (1) attend the first hospital clinic appointment; (2) receive the first macular laser, intravitreal anti-vascular endothelial growth factor injection or pan-retinal photocoagulation treatment, in either eye; and (3) lose at least ten ETDRS letters of distance visual acuity, in either eye., Results: Of 2062 referrals, 1676 individuals were included. Mean age (± SD) was 57.6 ± 14.7 years, with 52% male sex and 86% with type 2 diabetes. The ethnicity profile was 52% Black, 30% White, 10% Asian and 9% mixed/other, with similar disease severity at the time of referral. Time-to-clinic was significantly longer for Asian people than for Black people (p = 0.03) or White people (p = 0.001). Time-to-treatment was significantly longer for Black people than for White people (p = 0.02). Social deprivation did not significantly influence time-to-treatment. There were no significant differences in the rates of vision loss between ethnic groups., Conclusions/interpretation: Black people wait longer for hospital eye treatment compared with their White counterparts. The reasons for this delay in treatment warrant further investigation.
