Social participation and mild cognitive impairment in low- and middle-income countries.
Social participation may theoretically decrease risk for mild cognitive impairment (MCI). However, to date, no study has specifically investigated the association between social participation and MCI in LMICs, while the mediating role of loneliness is unknown. Thus, we investigated this association in a sample of adults aged ≥50 years from six low- and middle-income countries (LMICs; China, Ghana, India, Mexico, Russia, South Africa) using nationally representative datasets. ⋯ Loneliness only explained 3.0% of the association. Greater levels of social participation were associated with a reduced odds for MCI, and this was not largely explained by loneliness. It may be prudent to implement interventions in LMICs to increase levels of social participation to aid in the prevention of MCI and ultimately dementia.

Who owned the gun in firearm suicides of men, women, and youth in five US states?
One way to reduce firearm suicide is to keep household guns away from a person at risk for suicide. To learn who owned (and presumably controlled access to) the guns used in suicide and which broad gun type they were, we examined National Violent Death Reporting System (NVDRS) data from 2015 to 2017 for five US states that supplied information on gun owner in over 80% of firearm suicides (AK, IA, NH, UT, WI). For adult males, 88% used their own gun; for women, 52% used their own gun and 32% used their partner's gun; for youth ages 18-20, 42% used their own gun, 43% used a family member's, and 8% used a friend's; for children, 19% used their own gun (usually a long gun) and 79% used a family member's gun. ⋯ Storing firearms-or a critical component-away from home or having someone else control the locks may be safer. Five NVDRS states provided useful data on who owned the gun used in firearm suicides. More NVDRS states should follow suit.

Meta AnalysisHow effective are digital technology-based interventions at promoting colorectal cancer screening uptake in average-risk populations? A systematic review and meta-analysis of randomized controlled trials.
Despite the global prevalence of colorectal cancer (CRC) and efforts in screening advocacy, screening uptake remains relatively low. Considering the greater accessibility and popularity of telemedicine in behaviour change interventions, this meta-analysis seeks to examine the usefulness of digital interventions in promoting CRC screening uptake as compared to existing non-digital strategies. A systematic search on five databases identified articles published before September 2022. ⋯ Meanwhile, the tailored educational intervention subtype failed to achieve statistical significance in promoting screening uptake, bearing in mind the significant heterogeneity across studies (I2 = 88.6%). Digital decision-making aids significantly improved CRC screening uptake compared to tailored digital educational interventions and usual care. However, as all included studies were conducted in Western settings, its role in augmenting existing CRC screening promotion strategies especially among Asians should be further evaluated.

The association between vacant housing demolition and safety and health in Baltimore, MD.
We measured the association between vacant housing demolitions and changes in crime and emergency department (ED) visits in Baltimore, MD. We included 646 block groups in Baltimore, 224 of which experienced at least one demolition from 2012 to 2019. The exposure was the number of demolitions completed in a block group during the previous quarter. ⋯ Demolitions were associated with a small decrease in total ED visits (difference = -0.068 per 1000 people from the previous quarter to the current quarter, 95% CI -0.119, -0.018) but no significant change in crime. For each demolition, the rate of total child ED visits was 0.452 lower compared to the previous quarter (95% CI -0.777, -0.127). Demolitions were associated with small decreases in adult injury-related ED visits in the short term.

Trends in HPV- and non-HPV-associated vulvar cancer incidence, United States, 2001-2017.
Vulvar cancer incidence has been rising in recent years, possibly due to increasing exposure to human papillomavirus (HPV). We assessed incidence rates of HPV-associated and non-HPV-associated vulvar cancers diagnosed from 2001 to 2017 in the United States (US). Using population-based cancer registry data covering 99% of the US population, incidence rates were calculated and stratified by age, race/ethnicity, stage, geographic region, and histology. ⋯ HPV-associated vulvar cancer incidence increased overall and among women aged over 50 years while remaining stable among women younger than 50 years. The overall incidence for non-HPV-associated cancers was stable. Continued surveillance of HPV-associated cancers will allow us to monitor future trends as HPV vaccination coverage increases in the US.
