Characterizing Cognitive Dispersion and its Correlates Across the Adult Lifespan in MIDUS.

Objectives: Although research has shown that higher levels of within-person variability across cognitive tasks (dispersion) are associated with cognitive decline in clinical samples, little is known about dispersion in comparatively younger, non-clinical, and national samples. A better understanding of dispersion is needed to elucidate for whom and under what circumstances dispersion can be used as a reliable indicator of cognitive health.

Method: We used data from the Midlife in the United States Study (MIDUS; n = 2,229; Mage = 56 years, range = 33-83; 56% female) to: (a) characterize dispersion and its cross-sectional correlates in a non-clinical, adult lifespan sample and (b) examine changes in dispersion over time to determine for whom changes in dispersion may reflect better or worse cognitive aging.

Age and anxiety symptoms jointly moderated the curvilinear changes in trial-level ERN following repeated errors on a Go/No-Go task during early adolescence.

The ability to detect and monitor errors enables us to maintain optimal performance across tasks. One neurophysiological index of error monitoring is the error-related negativity (ERN), a fronto-central negative deflection peaking between 0 and 150 ms following an erroneous response. While the developmental literature has illustrated age-related differences in the ERN and its association with anxiety, the literature has mainly focused on the between-person differences of the ERN.

Campus Sexual Assault: A Qualitative Review and Meta-Synthesis of Students' Experiences of Campus Prevention Initiatives.

Sexual violence is a worldwide issue that impacts many individuals, often with serious and long-lasting effects. Students represent a high-risk group for sexual violence on campuses. As a result, various government initiatives have called for Universities and Colleges to develop policies and sexual violence prevention initiatives.

Phase I study of allogeneic monocyte-derived inflammatory dendritic cells in combination with pembrolizumab.

PD-1 checkpoint inhibition has revolutionized the care of cancer. A small portion of patients with stage IV cancer achieve durable control. But, early progression is common and dramatic control is achieved for only a minority.

Modern Methods for Unraveling Cell- and Circuit-Level Mechanisms of Neurophysiological Biomarkers in Psychiatry.

Methods for studying the mammalian brain in vivo have advanced dramatically in the past two decades. State-of-the-art optical and electrophysiological techniques allow direct recordings of the functional dynamics of thousands of neurons across distributed brain circuits with single-cell resolution. With transgenic tools, specific neuron types, pathways, and/or neurotransmitters can be targeted in user-determined brain areas for precise measurement and manipulation.

An expanding repertoire of circuit mechanisms for visual prediction errors.

Cortical responses to stimuli vary dependingon context and expectation. Adding insight into this process, Furutachi et al. recently demonstrated that higher-order thalamic input to visual cortex cooperates with interneurons to augment responses to unexpected stimuli, consistent with a body of literature implicating top-down modulation and local inhibition in predictive processing.

Discrimination based on gender identity and decision-making regarding HIV/STI-protected sex, a cross-sectional study among trans and non-binary people in Germany.

Background: Trans and non-binary people are often discriminated against. Discrimination has a negative impact on health and may affect sexual health and behavior. We explored the relationship between discrimination based on gender identity and the perceived ability to make decisions about their sex life to feel as protected as desired from HIV and sexually transmitted infections (STI) among trans and non-binary people in Germany.

Hearing Loss in Children with 22q11.2 Deletion Syndrome.

Objectives: Hearing loss is considered common in children with 22q11.2 deletion syndrome (22q11.2DS), with a few prior studies reporting a 32%-78% prevalence; mild-moderate conductive hearing loss has been reported most commonly.

Responsiveness and Reliability of a Sipping Device to Measure Motivation in Normal-Weight Individuals and Bariatric Surgery Patients.

There is an urgent need to measure the motivation to taste a sweet fluid in order to determine the influence of sweet tastes on the potential choices and consumption of beverages in patients with obesity. Current methods utilize either survey instruments or arbitrary operant tasks. The sipometer enables the participant to utilize an actual ingestive behavioral response to measure motivation during access to beverages on either ad libitum (AL) or progressive time ratio (PR) schedules.

Factors affecting academic motivation in undergraduate nursing students: A scoping review.

Aim: The aim of this scoping review was to discover literature identifying factors influencing academic motivation in undergraduate nursing students.

Background: Nursing students have a heavy academic workload, so self-motivated learning is important for them to succeed in the nursing program. There is a plethora of factors that influence the degree and type of motivation in nursing students.

When and how perceived control buffers against cognitive declines: A moderated mediation analysis.

Although perceived control is a well-established predictor of cognitive aging, less is known about how and under what developmental circumstances these beliefs about personal influence may protect against cognitive declines. Our study examined light physical activity (LPA) as an unexplored mechanism that may link changes in two facets of perceived control (personal mastery, perceived constraints) to longitudinal trajectories of cognitive functioning. We also examined whether mediated pathways were moderated by age (i.

The parasitic lifestyle of an archaeal symbiont.

DPANN archaea are a diverse group of microorganisms characterised by small cells and reduced genomes. To date, all cultivated DPANN archaea are ectosymbionts that require direct cell contact with an archaeal host species for growth and survival. However, these interactions and their impact on the host species are poorly understood.

The discovery of indazapyroxamet: a novel 3-pyridinyl insecticide targeting piercing/sucking insects.

In recent years, the registrations for a number of commercial insecticides utilized for piercing/sucking insects have been cancelled or restricted. To meet this growing need for new hemipteran controlling agrochemicals, we discovered a 2-(pyridin-3-yl)-thiazole compound, with limited insecticidal activity against cotton/melon aphid (Aphis gossypii). The 2-(pyridin-3-yl)-thiazole moiety offered us a basis to pursue the bicyclic 2-(pyridin-3-yl)-2H-indazole carboxamides.

Dynamic stereomutation of vinylcyclopropanes with metalloradicals.

The ever increasing demands for greater sustainability and lower energy usage in chemical processes call for fundamentally new approaches and reactivity principles. In this context, the pronounced prevalence of odd-oxidation states in less precious metals bears untapped potential for fundamentally distinct reactivity modes via metalloradical catalysis. Contrary to the well-established reactivity paradigm that organic free radicals, upon addition to a vinylcyclopropane, lead to rapid ring opening under strain release-a transformation that serves widely as a mechanistic probe (radical clock) for the intermediacy of radicals-we herein show that a metal-based radical, that is, a Ni metalloradical, triggers reversible cis/trans isomerization instead of opening.

'Follow the science': Popular trust in scientific experts during the coronavirus pandemic.

The coronavirus pandemic increased the role played by scientific advisers in counselling governments and citizens on issues around public health. This raises questions about how citizens evaluate scientists, and in particular the grounds on which they trust them. Previous studies have identified various factors associated with trust in scientists, although few have systematically explored a range of judgements and their relative effects.

The Effect of Contrast Rationing on the Development of Acute Kidney Injury During the Global Contrast Shortage.

Background: In April of 2022, the COVID-19 pandemic resulted in a global shortage of intravenous contrast media (ICM), which led our health care system to implement rationing measures.

Study Objectives: We set out to determine if the reduction in ICM use was associated with a change in the incidence of acute kidney injury (AKI).

Methods: We conducted a multicenter retrospective cohort analysis to compare the incidence of AKI in patients who presented before and after ICM rationing.

Psychotherapy on an Acute Psychiatric Ward: Preliminary Findings From a Controlled Study.

This study investigated the efficacy of psychotherapy during hospitalization on an acute psychiatric ward. A controlled trial was conducted to assess the effects of Metacognitive Reflection and Insight Therapy (MERIT) upon metacognition and psychiatric symptoms. Data from 40 inpatient women were analysed.

Frequency of deployed emergency donor panel use prior to implementation of the low titre group O whole blood program.

Introduction: The US military has frequently used a 'walking blood bank', formally known as an 'emergency donor panel' (EDP) to obtain warm fresh whole blood (WFWB) which is then immediately transfused into the casualty. We describe the frequency of EDP activation by the US military.

Methods: We analysed data from 2007 to 2015 within the Department of Defense Trauma Registry for US, Coalition and US contractor casualties that received at least 1 unit of blood product within the first 24 hours and described the frequency of WFWB use.

The four seasons of pancreatitis - Etiology of acute pancreatitis during the course of the year.

Background/objectives: Whether seasonality is a factor that influences the incidence of acute pancreatitis (AP) is an under-investigated area. If seasonal incidence peaks can be detected, specifically with regard to biliary pancreatitis, has so far been answered in contradictory ways in the literature.

Methods: All AP cases from two tertiary German referral centers were identified between 2016 and 2022 based on ICD-10 discharge codes.

Expression of gemcitabine metabolizing enzymes and stromal components reveal complexities of preclinical pancreatic cancer models for therapeutic testing.

Background: Pancreatic ductal adenocarcinoma (PDAC) poorly responds to antineoplastic agents. Discrepancies between preclinical success and clinical failure of compounds has been a continuous challenge and major obstacle in PDAC research.

Aim: To investigate the association of the tumor microenvironment (TME) composition and gemcitabine metabolizing enzyme (GME) expression in vitro and several in vivo models.

A Recovery-Oriented Approach: Application of Metacognitive Reflection and Insight Therapy (MERIT) for Youth with Clinical High Risk (CHR) for Psychosis.

Clinical High Risk for psychosis (CHR) refers to a phase of heightened risk for developing overt psychosis. CHR often emerges during adolescence or early adulthood. CHR has been identified as a group to target for intervention, with the hope that early intervention can both stave off prolonged suffering and intervene before mental health challenges become part of an individual's identity.

Selective lipid recruitment by an archaeal DPANN symbiont from its host.

The symbiont Ca. Nanohaloarchaeum antarcticus is obligately dependent on its host Halorubrum lacusprofundi for lipids and other metabolites due to its lack of certain biosynthetic genes. However, it remains unclear which specific lipids or metabolites are acquired from its host, and how the host responds to infection.

Long-Term Second Malignancies in Prostate Cancer Patients Treated With Low-Dose-Rate Brachytherapy and Radical Prostatectomy.

Purpose: Second malignancy is a rare but potentially lethal event after prostate brachytherapy, but data remain scarce on its long-term risk. The objective of this study is to estimate the number of pelvic second malignancies following brachytherapy compared to radical prostatectomy (RP).

Materials And Methods: We retrospectively reviewed patients treated with low-dose I brachytherapy and RP in British Columbia from 1999 to 2010.
