RESUMEN
OBJECTIVE: Identify depression symptoms during active late-life depression (LLD) that predict conversion to dementia. METHODS: The authors followed a cohort of 290 participants from the Neurocognitive Outcomes of Depression in the Elderly study. All participants were actively depressed and cognitively normal at enrollment. Depression symptom factors were derived from prior factor analysis: anhedonia and sadness, suicidality and guilt, appetite and weight loss, sleep disturbance, and anxiety and tension. Cox regression analysis modeled time to Alzheimer disease (AD) and non-AD dementia onset on depression symptom factors, along with age, education, sex, and race. Significant dementia predictors were tested for interaction with age at depression onset. RESULTS: Higher scores on the appetite and weight loss symptom factor were associated with an increased hazard of both AD and non-AD dementia. This factor was moderated by age at first depression onset, such that higher scores were associated with higher risk of non-AD dementia when depression first occurred earlier in life. Other depression symptom factors and overall depression severity were not related to risk of AD or non-AD dementia. CONCLUSION: Results suggest greater appetite/weight loss symptoms in active episodes of LLD are associated with increased likelihood of AD and non-AD dementia, but possibly via different pathways moderated by age at first depression onset. Results may help clinicians identify individuals with LLD at higher risk of developing AD and non-AD dementia and design interventions that reduce this risk.

Self-concept is a critical indicator of quality of life but few studies have examined this subject in children with Down syndrome (DS). In this study, we propose a novel methodology to assess the self-concept of children with DS by analyzing their responses towards two dolls, one with a "typically developing" (TD) appearance and one with the phenotypic features of DS. Fifty-four children with DS participated in play sessions with both dolls and were then interviewed to assess doll preference, resemblance, and attribution of positive qualities. We observed that children with DS: (i) exhibited a preference for the TD doll regardless of age, gender, IQ or self-awareness; (ii) attributed more positive qualities to the TD doll than the DS doll; and (iii) believed that they resembled the TD doll, rather than the more phenotypically accurate representation of themselves. Older participants were more likely to exhibit self-recognition by this technique. These findings contribute to current understandings of how people with DS view themselves and their disability.

A foreign body in the upper aerodigestive tract can be life-threatening. It is especially challenging for surgeons and anesthesiologists working in a limited shared workspace. A case is presented of an 83-year-old woman with end-stage dementia afflicted with oral fixation as defined as overeating or putting objects in the mouth other than food. She appeared asymptomatic although she had altered baseline mentation and was found to have ingested a large foreign object. This case provides an opportunity to discuss the unique challenges of performing anesthesia on patients undergoing the extraction of a large upper aerodigestive tract foreign body, complicated by end-stage dementia.
