Colloidal quantum dot-polymer hybrid light emitting diodes (QLEDs) that exhibit external quantum efficiencies >12% for all three primary colors (21% from green) have been demonstrated. These high efficiencies result in part from a positive aging effect reported here for the first time, where positive aging means the efficiency of the QLED increased with time. We have achieved 470 h operational life time (T90) at 2550 nits for red QLEDs. At longer times, negative aging phenomena lead to lower luminance and limit the lifetime of the QLEDs...

To understand the epidemiological variation in bacteremia characteristics among differently aged populations, adults with community-onset bacteremia during a 6-year period were studied in a retrospective cohort. A total of 2,349 bacteremic patients were stratified into four age categories: young adults (18-44 years old; 196 patients, 8.3%), adults (45-64; 707, 30.1%), the elderly (65-84; 1,098, 46.7%), and the oldest old (≥ 85; 348, 14.8%). Age-related trends in critical illness (a Pitt bacteremia score ≥ 4) at bacteremia onset, antibiotic-resistant pathogens (ESBL-producing Escherichia coli, Klebsiella species, and Proteus mirabilis [EKP]; methicillin-resistant Staphylococcus aureus [MRSA]; and levofloxacin non-susceptible EKP), inappropriate empirical antibiotic therapy (EAT), and 4-week mortality rate were observed...

Purpose: Regular physical activity is a key component of healthy aging, but few older adults meet physical activity guidelines. Poor aging expectations can contribute to this lack of activity, since negative stereotypes about the aging process can be internalized and affect physical performance. Although prior cross-sectional studies have shown that physical activity and aging expectations are associated, less is known about this association longitudinally, particularly among traditionally underrepresented groups...

Dementia worry, an anxiety-related response to the possibility of developing dementia, represents an important yet underexplored health concern for an aging population. Such a construct is likely impacted by stereotypes concerning aging, including biased associations of aging with inevitable cognitive decline. The present article explores the impact of mixed positive and negative aging stereotype messages on levels of dementia worry. The Fear of Alzheimer's Disease Scale (FADS) was used to measure impact of priming with different proportions of positive and negative aging stereotype words...

Chromosome 22q11.2 deletion syndrome (22q11DS) is a neurodevelopmental disorder associated with a broad phenotype of clinical, cognitive and psychiatric features. Due to the very high prevalence of schizophrenia (30-40%), the investigation of psychotic symptoms in the syndrome is promising to reveal biomarkers for the development of psychosis, also in the general population. Since schizophrenia is seen as a disorder of the dynamic interactions between brain networks, we here investigated brain dynamics, assessed by the variability of blood oxygenation level dependent (BOLD) signals, in patients with psychotic symptoms...

Robust data on hepatitis C virus (HCV) population prevalence are essential to inform national HCV services. In 2016, we undertook a survey to estimate HCV prevalence among the adult population in Ireland. We used anonymised residual sera available at the National Virus Reference Laboratory. We selected a random sample comprising persons ≥ 18 years with probability proportional to the general population age-sex distribution. Anti-HCV and HCV Ag were determined using the Architect anti-HCV and HCV Ag assays...

Very few studies have investigated mental health in sub-Saharan Africa (SSA). Using data from Malawi, this article provides a first picture of the demography of depression and anxiety (DA) among mature adults (aged 45 or older) in a low-income country with high HIV prevalence. DA are more frequent among women than men, and individuals affected by one are often affected by the other. DA are associated with adverse outcomes, such as poorer nutrition intake and reduced work efforts. DA also increase substantially with age, and mature adults can expect to spend a substantial fraction of their remaining lifetime-for instance, 52 % for a 55-year-old woman-affected by DA...

Objective Supraventricular arrhythmias are commonly detected in patients with anti-mitochondrial antibody M2 (AMA-M2)-associated myopathy. However, the prevalence of supraventricular arrhythmias in unselected AMA-M2-positive patients and the impact of AMA-M2 on supraventricular arrhythmias have yet to be fully investigated. Methods We analyzed 384 patients (116 men; age, 60 [48-69] years), who underwent AMA-M2 testing following the detection of elevated hepatobiliary enzymes. Supraventricular arrhythmias involving atrial fibrillation, atrial flutter, atrial tachycardia, sick sinus syndrome, and atrial standstill were confirmed by a 12-lead electrocardiogram, 24-hour ambulatory monitoring, and physician-assigned diagnoses within the three years before and two years after the AMA-M2 test...

Previous studies have examined the independent roles of positive age stereotypes (PAS) and negative age stereotypes (NAS) in successful aging. This study aimed to examine the joint effect of PAS and NAS on the well-being of Chinese older adults, and to further examine whether this effect was moderated by flexible goal adjustment (FGA). Using a cross-sectional design, 279 Chinese older adults (age range 60‒97 years) completed measures related to age stereotypes, FGA, and well-being. The results showed that PAS interacted with NAS to predict well-being...

BACKGROUND: Recent technological advances incorporated in high resolution manometry have justifiably heightened interest in manometric evaluation of the pharynx. Despite this interest, from both physiologic and clinical perspective there remain a number of unanswered questions regarding the magnitude of variability of pharyngeal pressure phenomena. Therefore, the aim of the present study was to characterize in healthy individuals the inter-subject and recording-site specific variability of pharyngeal peristaltic pressure phenomena...

Images of sexually active women beyond the age of 50 are lacking in popular culture and in particular on television. Dominant sexual scripts depict older women as generally asexual. The television program Hot in Cleveland features unpartnered midlife and older women as main characters. In this article, based on analysis of four seasons of Hot in Cleveland, we look closely at portrayals of sexual activity to see whether they underscore dominant sexual scripts mocking older women's sexual interest, position aging as sexual decline, or reinforce the narrative of "successful" aging/aging as progress...
