OBJECTIVE: Smoking as an epidemiological exposure can be quantified in many ways including duration, intensity, pack-years, recency, and age at initiation. However it is not clear which of these are most important for cardiovascular disease (CVD), and how they should be modeled. STUDY DESIGN AND SETTING: Using the Multi-Ethnic Study of Atherosclerosis, Cox models for time to incident CVD adjusted for age, sex, race/ethnicity, education category, and income category were compared which included various characterizations of smoking history...

Hunger is an everyday motivational state, which biases cognition to detect food. Although evidence exists on how hunger affects basic attentional and mnemonic processes, less is known about how motivational drive for food modulates higher cognition. We aimed to investigate the effects of food deprivation on proactive interference resolution, in the presence and absence of food. Normal-weight participants performed a recency probes paradigm providing an experimental block with food and object stimuli as well as a control block with object stimuli only, in a fasted and a sated state...

Previous correlational imaging studies have implicated the dorsolateral prefrontal cortex (DLPFC) in decision making. Using High-Definition Transcranial Direct Current Stimulation (HD-tDCS), the present study directly investigated the causal role of the DLPFC in performing the Iowa Gambling Task (IGT) and the Inter-Temporal Choice (ITC) task. Three experiments were conducted: Experiment 1 (N = 41) to study the left DLPFC, Experiment 2 (N = 49) to study the right DLPFC, and Experiment 3 (N = 20, a subset of those in Experiment 1) to switch the experimental and control conditions...

BACKGROUND: Recency effect suggests that people disproportionately value events from the immediate past when making decisions, but the extent of this impact on surgeons' decisions is unknown. This study evaluates for recency effect in surgeons by examining use of preventative leak testing before and after colorectal operations with anastomotic leaks. MATERIALS AND METHODS: Prospective cohort of adult patients (≥18 y) undergoing elective colorectal operations at Washington State hospitals participating in the Surgical Care and Outcomes Assessment Program (2006-2013)...

BACKGROUND: Alcohol intake may increase the risk of prostate cancer (PCa). Many previous studies harbored important methodological limitations. METHODS: We conducted a population-based case-control study of PCa comprising 1933 cases and 1994 controls in Montreal, Canada. Lifetime alcohol consumption was elicited, by type of beverage, during in-person interviews. Odds ratios (OR) and 95% confidence intervals (CI) assessed the association between alcohol intake and PCa risk, adjusting for potential confounders and considering the subjects' PCa screening history...

The Cognitive Assessment Interview (CAI) is an interview-based instrument to assess cognition considering the impact of cognitive impairment on daily activities. We aimed to explore the associations of the Spanish version of the CAI (CAI-Sp) with a neuropsychological battery and a measure of psychosocial functioning in psychosis. The sample consisted of fifty-six first episode psychosis (FEP) patients and 66 non-FEP patients, who were assessed with a neuropsychological battery, the CAI-Sp and the Short Disability Schedule (DAS-S)...

Proactive interference (PI) severely constrains how many items people can remember. For example, Endress and Potter (2014a) presented participants with sequences of everyday objects at 250ms/picture, followed by a yes/no recognition test. They manipulated PI by either using new images on every trial in the unique condition (thus minimizing PI among items), or by re-using images from a limited pool for all trials in the repeated condition (thus maximizing PI among items). In the low-PI unique condition, the probability of remembering an item was essentially independent of the number of memory items, showing no clear memory limitations; more traditional working memory-like memory limitations appeared only in the high-PI repeated condition...

BACKGROUND: Cross-sectional, biomarker methods to determine HIV infection recency present a promising and cost-effective alternative to the repeated testing of uninfected individuals. We evaluate a viral-based assay that uses a measure of pairwise distances (PwD) to identify HIV infection recency, and compare its performance with two serologic incidence assays, BED and LAg. In addition, we assess whether combination BED plus PwD or LAg plus PwD screening can improve predictive accuracy by reducing the likelihood of a false-recent result...

PURPOSE: To examine whether negative Facebook (FB) experiences were independently associated with depressive symptoms among young adults in a longitudinal family cohort. METHODS: Negative FB experiences were measured by type (e.g., bullying or meanness, unwanted contact, misunderstandings, or any), recency, number of experiences, and severity of upset. Depressive symptoms were assessed using the 10-item Center for Epidemiologic Studies Depression Scale. Generalized estimating equations were used to account for sibling correlation; adjusted models were constructed for each negative FB experience measure accounting for sex, race/ethnicity, social support, adolescent depressive symptoms, parental psychological distress, average monthly income, educational attainment, and employment...

OBJECTIVE: HIV seroconversion biomarkers are being used in cross-sectional studies for HIV incidence-estimation. Bio-Rad Geenius HIV1/2 Supplemental Assay is an immunochromatographic single-use assay that measures antibodies (Ab) against multiple HIV-1/2 antigens. The objective of this study was to determine whether the Geenius assay could additionally be used for recency estimation. DESIGN: This assay was developed for HIV-1/2 confirmation; however, quantitative data acquired gives information on increasing concentration and diversity of antibody responses over time during seroconversion...

Apart from ultrastructural damages in oocytes subjected to cryopreservation procedures, little is known about the status of epigenetic modification and chromatin remodeling in vitrified oocytes. In present study, the expression patterns of eight genes involved in epigenetic modification (HAT1, HDAC1, SUV39H1, DNMT1, and DNMT3b), chromatin remodeling (HMGN3a and SMARCAL1), and transcription (STAT3), were investigated in fresh and vitrified germinal vesicle and metaphase II oocytes and their resulting embryos at 2 to 7 cells, 8 to 16 cells, morula, and blastocyst stages...

This study investigated the relationship between experiential avoidance, coping and the recency and frequency of self-harm, in a community sample (N = 1332, aged 16-69 years). Participants completed online, self-report measures assessing self-harm, momentary affect, experiential avoidance and coping in response to a recent stressor. Participants who had self-harmed reported significantly higher levels of experiential avoidance and avoidance coping, as well as lower levels of approach, reappraisal and emotional regulation coping, than those with no self-harm history...

Liver cancer incidence has been rising rapidly in Western countries. Nonsteroidal anti-inflammatory drugs (NSAIDs) and paracetamol are widely-used analgesics that may modulate the risk of liver cancer, but population-based evidence is limited. We conducted a case-control study (1195 primary liver cancer cases and 4640 matched controls) within the United Kingdom's Clinical Practice Research Datalink to examine the association between the use of prescription NSAIDs and paracetamol and development of liver cancer...

OBJECTIVE: To assess the utility of cost-effective dried blood spot (DBS) field sampling for incidence and drug resistance surveillance of persons at high risk for HIV infection. METHODS: We evaluated DBS collected in 2007-2010 in non-clinical settings by finger-stick from HIV-positive heterosexuals at increased risk of HIV infection (n = 124), men who have sex with men (MSM, n = 110), and persons who inject drugs (PWID, n = 58). Relative proportions of recent-infection findings among risk groups were assessed at avidity index (AI) cutoffs of ≤25%, ≤30%, and ≤35%, corresponding to an infection mean duration of recency (MDR) of 220...

Performance was examined on three variants of the spontaneous object recognition (SOR) task, in 5-month old APPswe/PS1dE9 mice and wild-type littermate controls. A deficit was observed in an object-in-place (OIP) task, in which mice are preexposed to four different objects in specific locations, and then at test two of the objects swap locations (Experiment 2). Typically more exploration is seen of the objects which have switched location, which is taken as evidence of a retrieval-generated priming mechanism...

The contributions of hemispheric-specific electrophysiology (electroencephalogram or EEG) and independent executive functions (inhibitory control, working memory, cognitive flexibility) to episodic memory performance were examined using abstract paintings. Right hemisphere frontotemporal functional connectivity during encoding and retrieval, measured via EEG alpha coherence, statistically predicted performance on recency but not recognition judgments for the abstract paintings. Theta coherence, however, did not predict performance...

The shift from recency to primacy with delay reflects a fundamental observation in the study of memory. As time passes, the accessibility of earlier-learned representations tends to increase relative to the accessibility of later-learned representations. In three experiments involving participants' memory for text materials, we examined whether participants understood that there might be such a shift with retention interval. In marked contrast to their actual performance, participants predicted recency effects at both shorter and longer retention intervals...

Classical explanations for the modality effect-superior short-term serial recall of auditory compared to visual sequences-typically recur to privileged processing of information derived from auditory sources. Here we critically appraise such accounts, and re-evaluate the nature of the canonical empirical phenomena that have motivated them. Three experiments show that the standard account of modality in memory is untenable, since auditory superiority in recency is often accompanied by visual superiority in mid-list serial positions...
