CONTEXT: The homeless population is aging. Older homeless adults experience premature development of age-related conditions and an elevated symptom burden. Little is known about symptom experience among older homeless adults. OBJECTIVES: To characterize the experience, understanding, and management of physical, psychological, social (e.g. loneliness), and existential (e.g. regret, loss of dignity) symptoms among older homeless adults. METHODS: We conducted semi-structured interviews from June 2016 through March 2017 with a purposive sample of participants from the HOPE HOME cohort, a longitudinal study of homeless adults ages 50 and older...

Patients receiving cytokine immunotherapy with IFN-α frequently present with neuropsychiatric consequences and cognitive impairments, including a profound depressive-like symptomatology. While the neurobiological substrates of the dysfunction that leads to adverse events in IFN-α-treated patients remains ill-defined, dysfunctions of the hippocampus and prefrontal cortex (PFC) are strong possibilities. To date, hippocampal deficits have been well-characterised; there does however remain a lack of insight into the nature of prefrontal participation...

BACKGROUND: Recovery from stroke-induced aphasia is typically protracted and involves complex functional reorganization. The relative contributions of the lesioned and non-lesioned hemispheres to this process have been examined in several cross-sectional studies but longitudinal studies involving several time-points and large numbers of subjects are scarce. OBJECTIVE: The aim of this study was to address the gaps in the literature by longitudinally studying the evolution of post-stroke lateralization and localization of language-related fMRI activation in the first year after single left hemispheric ischemic stroke...

Past research on emotional clarity (EC), the ability to identify and label one's own emotions, has illustrated an association between EC deficits and poor psychosocial outcomes during the adolescent years. Although past research has connected EC to psychosocial outcomes during adolescence in cross-sectional and longitudinal designs, no studies have traced the trajectory of EC over time to determine the developmental course of the construct during adolescence. Thus, this study investigated how EC developed over five years during adolescence and what factors were associated with the developmental trajectory of emotional clarity...

Heavy cannabis use is associated with a wide array of physical, mental, and functional problems. Therefore, cannabis use disorders (CUDs) may be a major public health concern. Given the adverse health consequences of CUDs, the present study seeks to find possible precursors of CUDs. The current study consisted of 5 waves of data collection from the Harlem Longitudinal Development Study. Among 816 participants, about half are African Americans (52%), and the other half are Puerto Ricans (48%). We used Mplus to obtain the triple trajectories of alcohol use, tobacco use, and depressive symptoms...

Surface ligand modification of colloidal semiconductor nanocrystals has been widely used as a means of controlling photoexcited state generation, relaxation, and coupling to the environment. While progress has been made in understanding how surface ligand modification affects the behavior of excitonic states, less is known about the influence of surface ligand modification on phonon behavior, which impacts relaxation dynamics and transport phenomena. In this work we compare the dynamics of optical and acoustic phonons in CdTe quantum dots (QDs), CdTe/CdSe core/shell QDs capped with octadecylphosphonic acid ligands, and CdTe QDs capped with Se2- to ascertain how ligand exchange from native aliphatic ligands to single-atom Se2- ligands affects phonon behavior...

Introduction : Increased variability in motor function has been observed during the initial stages of cognitive decline. However, the natural variability of postural control, as well as its association with cognitive status and decline, remains unknown. The objective of this pilot study was to characterize the day-to-day variability in postural sway in non-demented older adults. We hypothesized that older adults with a lower cognitive status would have higher day-to-day variability in postural sway. Materials and Methods : A Nintendo Wii balance board (WBB) was used to quantify postural sway in the home twice daily for 30 days in 20 non-demented, community-dwelling older adults: once under a single-task condition and once under a dual-task condition (using a daily word search task administered via a Nook tablet)...

BACKGROUND: Marijuana use during adolescence is associated with neurocognitive deficits and poorer functioning across several domains. It is likely that more states will pass both medical and recreational marijuana legalization laws in the coming elections; therefore, we must begin to look more closely at the longitudinal effects of medical marijuana (MM) advertising on marijuana use among adolescents so that we can better understand effects that this advertising may have on their subsequent marijuana use and related outcomes...

AIM: Cardiovascular disease and mental illness commonly co-occur in later life, but it is unknown how early these associations arise. We aimed to determine the extent to which: (i) childhood mental health is associated with functional and structural cardiovascular risk phenotypes and adiposity in late childhood/adolescence, and (ii) associations between mental health and cardiovascular phenotypes may be explained by differential body mass index. METHODS: This cross-sectional study drew on three longitudinal community-based cohort studies (two enriched for overweight/obesity) in metropolitan Melbourne, Australia, with harmonized follow-up in 2014...

BACKGROUND: Health-related quality of life (HRQoL) is an important outcome in coronary heart disease (CHD). However, variability in HRQoL indicators suggests a need to consider domain coverage. This review applies a globally accepted framework, the International Classification of Functioning, Disability and Health (ICF), to map HRQoL measures that are reliable and valid among people with CHD. METHODS: The Embase, Pubmed and PsycInfo databases were searched, with 10 observational studies comparing HRQOL among 4786 adults with CHD to 50949 controls identified...

AIM: To comparatively investigate the effects of hyperpolypharmacy and potentially inappropriate medications (PIMs) on functional decline in older patients after hospital discharge. METHODS: Our series consisted of 733 patients aged ≥65 consecutively enrolled in a multicenter observational longitudinal study. PIMs were defined on the basis of updated versions of Beers and STOPP criteria. The occurrence of functional decline was defined as the loss of independency in at least 1 basic activity of daily living (BADL) from discharge through 3-month follow-up visit...

OBJECTIVES: We investigated whether global longitudinal strain (GLS) is a better predictor of clinical events after surgery for mitral regurgitation (MR) than conventional parameters. BACKGROUND: The optimal timing for surgery is guided by left ventricular (LV) dimension or left ventricular ejection fraction (LVEF), even though normal LVEF can mask depressed LV systolic function in severe mitral MR. METHODS: From 2006 to 2016, 506 patients (age 58...

BACKGROUND: fMRI blood oxygenation level-dependent (BOLD) signal has been widely used as a surrogate for neural activity. However, interpreting differences in BOLD fMRI based on underlying neuronal activity remains a challenge. Concurrent rsMRI data collection and electrophysiological recording in combination with microiontophoretically injected modulatory chemicals allows for improved understanding of the relationship between resting state BOLD and neuronal activity. NEW METHODS: Simultaneous fMRI, multi-channel intracortical electrophysiology and focal pharmacological manipulation data to be acquired longitudinally in rats for up to 2 months...

Recent studies highlighted the role of mitochondrial dysregulation in cancer, suggesting that the different mitochondrial haplogroups might play a role in tumorigenesis and risk of cancer development. Our aim is to investigate whether any mitochondrial haplogroups carried a significant higher risk of cancer development in a large prospective cohort of North American people. The haplogroup assignment was performed by a combination of sequencing and PCR-RFLP techniques. Our specific outcome of interest was the incidence of any cancer during follow-up period...

The effects of a delayed school start time by one hour were examined at a boarding school in Hong Kong. Two cohorts of high school students (N = 228; 61.8% female) were recruited respectively before and after a school start time changed from 7:30am to 8:30am. Both cross-cohort and within-cohort longitudinal comparisons yielded significant increase in total sleep time. Cross-cohort comparison yielded improvement in sleep quality, insomnia, life satisfaction, and psychological distress. Longitudinal data suggested that the longer the additional sleep time, the better was sleep quality, day-time functioning, and subjective wellbeing...
