BACKGROUND: Inflammatory bowel diseases (IBD) are severe medical conditions with adverse impact on the quality of life of both children and their caregivers. IBD are associated with many limitations in personal and interpersonal functioning, and it also restricts the patients' ability to use the full potential (extent) of their capabilities. With the progress and humanization in society, the issue of patients' needs became an important topic; however, the psychosocial functioning and quality of life of adolescents suffering from IBD and their caregivers have been understudied...

PURPOSE: We compared 1-year outcomes of 1 + pro re nata (PRN) versus 3 + PRN of intravitreal aflibercept injection (IAI) for age-related macular degeneration (AMD). METHODS: Forty-two eyes with naïve AMD received 3 + PRN IAI treatment and 47 eyes with naïve AMD received 1 + PRN IAI treatment. Visual acuity (VA), central retinal thickness (CRT), and central choroidal thickness (CCT) and number of administered IAIs during 12 months were compared. RESULTS: VAs improved, and CRTs reduced significantly at any given month from baseline in both groups (p < 0...

A recent alarming rise of neurodegenerative diseases in the developed world is one of the major medical issues affecting older adults. In this review, we provide information about the associations of physical activity (PA) with major age-related neurodegenerative diseases and syndromes, including Alzheimer's disease, vascular dementia, and mild cognitive impairment. We also provide evidence of PA's role in reducing the risks of these diseases and helping to improve cognitive outcomes in older adults. Finally, we describe some potential mechanisms by which this protective effect occurs, providing guidelines for future research...

: Background/Study Context: Previous studies found that older adults tend to remember more positive than negative information (i.e., positivity bias), leading to an age-related positivity effect. However, the extent to which factors of arousal and contextual information influence the positivity bias in older adults remains to be determined. METHODS: In this study, 27 Chinese younger adults (20.00 ± 1.75 years) and 33 Chinese older adults (70.76 ± 5.49) learned pictures with negative, positive, and neutral valences...

: Background/Study Context: Previous research (Hess et al., 2013, Psychology and Aging, 28, 853-863) suggested that age-based positivity effects in memory were attenuated with social stimuli. This research examined the degree to which this generalized across arousal levels associated with social images. Variations in approach and avoidance responses to individual images were also examined, along with age differences in their relationship to memory performance. METHODS: In Experiment 1, young (22-43 years) and older (65-85 years) adults recalled positive and negative social scenes that were high or low in arousal...

: Background/Study Context: The age-related differences in divided attention and attentional control have been associated with several negative outcomes later in life. However, numerous questions remain unanswered regarding the nature of these age differences and the role of attentional control abilities in dual-tasking. The aim of this study was to evaluate the sources for age differences in dual-tasking and more specifically: (1) whether they occur because of differences in attentional control skills, or (2) whether the age-related decrement in dual-tasking is due to a general resource reduction that would affect the ability to complete any demanding task...

Views on aging have been shown to predict the occurrence of events related to physical health in previous studies. Extending these findings, we investigated the relation between aging-related future self-views and life events in a longitudinal study across a range of different life domains. Participants (N = 593, age range 30-80 years at t1) completed a survey at 2 measurement occasions that were separated by a 4-year interval (t1: 2009, t2: 2013), providing information on domain-specific future self-views as well as on life events that had occurred in the respective domains in-between the 2 measurement occasions...

Episodic memory, future thinking, and memory for scenes have all been proposed to rely on the hippocampus, and evidence suggests that these all decline in healthy aging. Despite this age-related memory decline, studies examining the effects of context reinstatement on episodic memory have demonstrated that reinstating elements of the encoding context of an event leads to better memory retrieval in both younger and older adults. The current study was designed to test whether more familiar, real-world contexts, such as locations that participants visited often, would improve the detail richness and vividness of memory for scenes, autobiographical events, and imagination of future events in young and older adults...

: Literature suggests that pain perception diminishes in old age. The most recent review used search strategies conducted over a decade ago and concluded that study findings were equivocal. The aim of this systematic review, with meta-analysis, was to determine age-related changes in pain sensitivity in healthy pain-free adults, children and adolescents. A search of PubMed, Science Direct, and PsycINFO identified studies that compared pain sensitivity response to noxious stimuli at different time points in the lifespan of healthy individuals...

With aging, there is progressive loss of tissue homeostasis and functional reserve, leading to an impaired response to stress and an increased risk of morbidity and mortality. A key mediator of the cellular response to damage and stress is the transcription factor NF-κB. We demonstrated previously that NF-κB transcriptional activity is upregulated in tissues from both natural aged mice and in a mouse model of a human progeroid syndrome caused by defective repair of DNA damage (ERCC1-deficient mice). We also demonstrated that genetic reduction in the level of the NF-κB subunit p65(RelA) in the Ercc1(-/∆) progeroid mouse model of accelerated aging delayed the onset of age-related pathology including muscle wasting, osteoporosis, and intervertebral disk degeneration...

Age-related hearing loss (ARHL) is postulated to affect dementia. Our study aims to investigate the relationship between ARHL and the prevalence, and 10-year incidence of dementia in the Taiwan National Health Insurance Research Database (NHIRD). We selected patients diagnosed with ARHL from the NHIRD. A comparison cohort comprising of patients without ARHL was frequency-matched by age, sex, and co-morbidities, and the occurrence of dementia was evaluated in both cohorts. The ARHL cohort consisted of 4108 patients with ARHL and the control cohort consisted of 4013 frequency-matched patients without ARHL...

OBJECTIVE: The enteric nervous system (ENS) undergoes neuronal loss and degenerative changes with age. The cause of this neurodegeneration is poorly understood. Muscularis macrophages residing in close proximity to enteric ganglia maintain neuromuscular function via direct crosstalk with enteric neurons and have been implicated in the pathogenesis of GI motility disorders like gastroparesis and postoperative ileus. The aim of this study was to assess whether ageing causes alterations in macrophage phenotype that contributes to age-related degeneration of the ENS...

During heat stress, blunted increases in skin sympathetic nervous system activity (SSNA) and reductions in end-organ vascular responsiveness contribute to the age-related reduction in reflex cutaneous vasodilation. In older adults, folic acid supplementation improves the cutaneous vascular conductance (CVC) response to passive heating; however, the influence of folic acid supplementation on SSNA:CVC transduction is unknown. Fourteen older adults (66±1yrs, 8M/6F) ingested folic acid (5mg·day(-1)) or placebo for 6 weeks in a randomized, double-blind, crossover design...

Predicting age-specific metabolism is important for evaluating age-related drug and chemical sensitivity. Multiple cytochrome P450s (CYP) and carboxylesterase (CES) enzymes are responsible for human pyrethroid metabolism. Complete ontogeny data for each enzyme is needed to support in vitro to in vivo extrapolation (IVIVE). This study was designed to determine age-dependent human hepatic CYP2C8 expression, for which only limited ontogeny data are available, and to further define CYP1A2 ontogeny. CYP2C8 and 1A2 protein levels were measured by quantitative Western blotting using liver microsomal samples prepared from 222 subjects with ages ranging from 8 weeks gestation to 18 years after birth...

Corneal endothelial cells (CECs) are essential for maintaining corneal stromal hydration and ensuring its transparency, which is necessary for normal vision. Dysfunction of CECs leads to stromal decompensation, loss of transparency and corneal blindness. Corneal endothelium has low proliferative potential compared to surface epithelial cells leading to poor regeneration of CEC following injury or age related decline in cellular density. The mechanisms which control proliferation and differentiation of neural crest derived CEC progenitors are yet to be clearly elucidated...

Variants of the CFH gene, encoding complement factor H (CFH), show strong association with age-related macular degeneration (AMD), a major cause of blindness. Here, we used murine models of AMD to examine the contribution of CFH to disease etiology. Cfh deletion protected the mice from the pathogenic subretinal accumulation of mononuclear phagocytes (MP) that characterize AMD and showed accelerated resolution of inflammation. MP persistence arose secondary to binding of CFH to CD11b, which obstructed the homeostatic elimination of MPs from the subretinal space mediated by thrombospsondin-1 (TSP-1) activation of CD47...

We aimed to evaluate the effects of acute heat stress (HS) and age on the redox state in broilers aged 21 and 42 days. We evaluated the expression of genes related to antioxidant capacity, the production of hydrogen peroxide (H2O2), and the activity of antioxidant enzymes in the liver, as well as oxidative stress markers in the liver and plasma. The experiment had a completely randomized factorial design with two thermal environments (thermoneutral and HS, 38°C for 24 h) and two ages (21 and 42 days). Twenty-one-day-old animals exposed to HS showed the highest thioredoxin reductase 1 (TrxR1) (P<0...
