Background: Previous studies have examined the relation between attention problems (APs) obtained with the Child Behavior Checklist (CBCL) and attention deficit hyperactivity disorder (ADHD) assessed with the Diagnostic and Statistical Manual of Mental Disorders (DSM). We will examine this relation across sex using multi-informant data.
Methods: Parents of 12538 twins, aged 7, 10, and 12 years, and teachers of twins, aged 10 years, completed the questionnaires. The mothers of a sample of 283 boys and 291 girls who scored either low or high on longitudinal maternal CBCL-AP were interviewed.
Results: Children with a low AP score obtained a negative ADHD diagnosis in 96% of cases. Children with a high AP score obtained a positive diagnosis in 36% (girls) and 59% (boys) of cases. The association between paternal and maternal AP ratings and ADHD was the same, whereas the association between teacher AP ratings and ADHD was low.
Conclusions: The association between AP and ADHD is higher in boys than girls, possibly because of a bias toward the male manifestation of ADHD.

Background: Subjective Cognitive Complaints (SCCs) can often precede mild cognitive impairment and dementia longitudinally. While increasingly considered an early prodromal stage of dementia, SCCs can also be a symptom of depression. Previous research found that SCCs in the absence of cognitive impairment, controlling for symptoms of depression, were moderately heritable and genetically associated with memory.

Background: DNA methylation (DNAm) age measures, or 'epigenetic clocks', surpass chronological age in their ability to predict age-related morbidities and mortality. The Louisville Twin Study (LTS) presents an opportunity to clarify the role of early life environmental exposures and development in biological and cognitive aging in midlife. We expect that second-generation DNAm age measures trained to predict age related outcomes and death, independent of chronological age, will be sensitive to cognitive ability in midlife.

Background: Previous genome-wide association studies (GWAS) have established association between genetic variants and pulmonary function across various ethnics, whereas such associations are scarcely reported in Chinese adults. Therefore, we conducted an GWAS to explore relationships between genetic variants and pulmonary function among middle-aged Chinese dizygotic twins and further validated the top variants using data from the UK Biobank (UKB).
Methods: In the discovery phase, 139 dizygotic twin pairs were drawn from the Qingdao Twin Registry.

Background & Aims: Suboptimal diets increase morbidity and mortality risk. Epigenetic clocks are algorithms that can assess health and lifespan, even at a young age, before clinical manifestations of diseases. We investigated the association between dietary patterns and biological aging in young adult twins.

Alkaptonuria is a rare inherited disease resulting from a genetic variant leading to homogentisic acid accumulation in body tissues, causing a broad spectrum of symptoms. Our case involves a Caucasian male diagnosed in his 70s, who shares a constellation of symptoms and the diagnosis with his monozygotic twin brother. The symptoms include early-onset arthropathy, tendinopathy, osteopenia, discolouration of the auricular regions and fingers, scleral discolouration, secondary glaucoma, proteinuria, calcification of the mitral valve and black urethral and prostate stones.
