Objectives: We aimed to analyse the trends of interpersonal violence (IV) in Latin America (LA) between 1990 and 2019 for females and males at a national level., Study Design: Cross-sectional descriptive study., Methods: Following the 2019 Global Burden of Disease study we report IV mortality, premature mortality, years lived with disability and disability-adjusted life-years (DALYs) in LA by sex. To estimate the DALYs trends, we conducted a Joinpoint regression analysis., Results: Across all LA countries, IV burden was higher among males. Most of the IV burden was attributable to premature death, with a higher percentage in men than women. The burden of IV was most pronounced within the 15 to 39 age-groups in the majority of countries. Physical violence (PV) by firearm was the main cause of IV in LA, followed by PV by other means. Women in LA experienced at least twice as many sexual violence DALYs as men. IV in LA exhibited heterogeneous trends, with certain countries witnessing a significant decline in the IV DALYs rate, while others displayed a significant increase., Conclusions: Our results show the great heterogeneity of IV burden present in the region as the trends varied from one country to another. Policing and criminal justice institutions in LA have failed to reduce crime and violence. Thus, tailored preventive measures and public policies that account for the specific context and geographical areas where this phenomenon is prevalent are urgently needed., (Copyright © 2024 The Royal Society for Public Health.

Introduction: Morphologic features of the mandible are influenced by the genes of each individual. Mandible size is important to orthodontists because the mandible is the mechanism by which the lower face influences facial esthetics and dental function. To date, no biological marker has been identified that indicates eventual mandible size. This study aimed to correlate the expression of DLX5, DLX6, EDN1, HAND2, PRRX1, and MSX1 to mandible size., Methods: Fifty-nine orthodontic patients aged >6 years who had available cephalometric radiographs were studied. Patients were classified on the basis of condylion-to-gnathion measurements. Messenger RNA was isolated from saliva and subjected to real-time quantitative polymerase chain reaction., Results: Threshold cycle values for subjects with small mandibles (>1 standard deviation [SD] from the mean) had the least expression of DLX6 and MSX1. Threshold cycle values for subjects with large mandibles (>1 SD) had less expression of DLX6 and MSX1 than subjects within 1 SD but more than those with small mandibles., Conclusions: DLX6 and MSX1 are related to mandible development and size. This finding could be used to improve treatment planning for medical and dental professionals seeking to understand the impact of genetics on bone growth., (Copyright © 2022 American Association of Orthodontists.

Importance: Injuries have been a major cause of premature mortality and short-term and long-term disability in Mexico., Objective: To report the findings from the Global Burden of Disease 2019 study on injuries in Mexico at a national and subnational scale from 1990 to 2019., Methods: Following the 2019 Global Burden of Disease study we examined injury mortality, premature mortality, years lived with disability and disability-adjusted life-years according to 14 subcategories. We calculated the Pearson correlation coefficient between the injury burden and the socio-demographic index., Results: While the number of deaths from injuries increased significantly, the changes in the age-standardized mortality rates trended towards declines. Interpersonal violence, road injuries, falls and self-harm accounted for 8 of every 10 deaths from injury in 2019. Injury mortality and the disability-adjusted life-years rates decreased nationally and in most states in the period as a whole, but have increased since 2007. The injury burden was higher for men in all age groups. Interpersonal violence caused the highest disability-adjusted life-years rate in males and road injuries in females. The socio-demographic index increased in all states, while the injury age-standardized disability-adjusted life-years rates between 1990 and 2019 decreased, but there was no statistical association between both indicators., Discussion and Conclusions: This study represents a comprehensive review of injury burden of disease in Mexico. The injury burden decreased, but improved heterogeneously among states. To further reduce the injury burden of disease, it's necessary for federal, state and local governments to prioritize safety promotion and injury prevention programs, infrastructure improvements, legislation, and enforcement at a national and subnational level. Mexico's injury prevention efforts should also be tailored for specific age groups, such as males aged 20-49 years or females in the younger and older age groups, and high-burden areas., Competing Interests: Declarations of Competing Interest None declared by the authors., (Copyright © 2021.

Objectives: Colombia is considered one of the most violent countries in the world even though homicide mortality has decreased since 2002. Mexico's homicide rate has tripled since 2008, after a period of decreasing mortality; this fact has been compared with Colombia in the 1990s and defined as a 'Colombianization' of violence in Mexico. We analyzed and compared the trend and impact of homicide mortality in Colombia and Mexico between 1998 and 2015., Study Design: Cross-sectional descriptive study., Methods: We calculated the standardized mortality rates and the years of life lost using data from the National Institute of Statistics and Geography in Mexico and the National Management Department of Statistics in Colombia. We used the joinpoint regression analysis to identify significant changes in the mortality trend., Results: During the 1990s, Colombia reached the highest homicide mortality rates in the world, but these rates have since decreased significantly. In Mexico, homicide mortality had a decreasing trend from 1998 to 2007; however, since 2008, the rate grew significantly, and although mortality tended to decrease after reaching its peak in 2011, a slight upturn was observed in 2015., Conclusions: We found that the trend in mortality in both countries has had certain similarities, such as the increase in mortality after the implementation of antidrug policies and the subsequent decrease; however, the political processes, the level of mortality reached, its impact on life expectancy, and its distribution by gender are dissimilar. We consider speaking of a 'Colombianization' of violence in Mexico to be inaccurate., (Copyright © 2018 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.)
