[Ab] Abstract:BACKGROUND: Exposure to environmental phenols including parabens, bisphenols (BPs), oxybenzone/benzophenone-3 (BP-3) and triclosan (TCS) is ubiquitous. Due to evidence of their estrogenic activity, they have been considered as chemicals of concern. The exposure of the Norwegian population to these compounds is presently unknown. AIMS: To measure urinary levels of twelve different environmental phenols including four emerging bisphenols: S, F, B and AF (abbreviated as BPS, BPF, BPB and BPAF, respectively) in a healthy Norwegian population. We have calculated short-term variability, estimated daily intakes and investigated important determinants of exposure. METHODS: Urine samples were collected from mothers (n = 48) and their children (n = 56) during spring/summer 2012 in two counties in Norway. RESULTS: Six environmental phenols namely methyl, ethyl and propyl paraben, BPA, BP-3 and TCS were detected in almost 100% of the urine samples. Among the emerging bisphenols, BPS was detected most frequently in the urine samples (42-48%) followed by BPF (4-15%). Parabens were positively and significantly correlated to each other in both mothers and children. Levels of parabens and BP-3 were higher in mothers compared to children. All mothers and children had lower estimated daily intakes (back calculated from the urinary concentrations) of parabens and BPA than the respective acceptable and tolerable daily intakes (ADIs and TDIs) established by the European Food Safety Authority (EFSA). Observed intraclass correlation coefficients (ICCs) indicated moderate to high reliability of spot urine measurements for all the environmental phenols (ICCs: 0.70-0.97). Use of hair products, deodorants, face and hand creams were significantly associated with higher urinary levels of parabens. CONCLUSIONS: Occurrence of environmental phenols in healthy Norwegian women and children is abundant. Among emerging bisphenols, there is widespread exposure to BPS. A single spot urine sample can be used for estimating short-term exposures of environmental phenols. Urinary levels of parabens were associated with use of PCPs.

[Ab] Abstract:BACKGROUND: Operating theatre services can be heavily relied upon during mass casualty disaster events, which require nurses to have adequate training and education of hospital disaster management plans to respond appropriately. The evidence-base of disaster preparedness in the acute setting is limited, particularly with regard to operating theatre nurses. OBJECTIVES: Explore operating theatre nurse's disaster knowledge of their role in a mass casualty event, and identify the preferred mode of disaster education and training to improve disaster preparedness. DESIGN: A cross-sectional research design was employed with data collected using a survey tool. SETTINGS: The research was undertaken on operating theatre nurses in a tertiary hospital in Victoria, Australia. PARTICIPANTS: The participants in this research included 53 operating theatre nurses, 51 Registered Nurses and 2 Enrolled Nurses. METHODS: The survey was based on a disaster questionnaire for emergency department nurses from South Australia, exploring knowledge and preparedness for disaster response in the acute setting, and altered to be specific and relevant to the operating theatre environment and broadened to focus on the training needs of perioperative nurses. RESULTS: The survey of 53 operating theatre nurses identified that few had previous disaster experience (19.9%). The majority of respondents were aware of their disaster management policy (Code Brown policy) (94.1%), of reporting lines, and appropriate triage (80.4%). However, a significant number of nurses (50.9%) stated that in the event of a disaster they would "call work to see if [they needed] additional assistance" compared with 43.4% of respondents "wait to be contacted by a manager/floor coordinator" as was policy. Finally, disaster nursing general knowledge amongst staff was poor; a mean of 1.79 (SD = 1.20) correct answers out of a possible 7. CONCLUSIONS: This study highlights that disaster education and training methods for disasters be specific to the role required by nurses and all staff during a disaster activation; training drills are preferred although face-to-face education is practical.

[Ab] Abstract:OBJECTIVE: this study explores women's experiences of the first two months after obstetric anal sphincter injury (OASIS) during childbirth with a focus on problematic recovery. METHODS: this qualitative study used inductive qualitative content analysis to investigate open-ended responses from 1248 women. The data consists of short and comprehensive written responses to open-ended questions focusing on recovery in the national quality register, the Perineal Laceration Register, two months after OASIS at childbirth. RESULTS: the theme 'A worse nightmare than expected' illustrated women's experiences of their life situation. Pain was a constant reminder of the trauma, and the women had to face physical and psychological limitations as well as crushed expectations of family life. Furthermore, navigating healthcare services for help added further stress to an already stressful situation. CONCLUSIONS: we found that women with problematic recovery two months after OASIS experienced their situation as a worse nightmare than expected. Extensive pain resulted in physical and psychological limitations, and crushed expectations of family life. Improved patient information for women with OASIS regarding pain, psychological and personal aspects, sexual function, and subsequent pregnancy delivery is needed. Also, there is a need for clear organizational structures and information to guide help-seeking women to needed care.

[Ti] Title:Is it about me? Time-course of self-relevance and valence effects on the perception of neutral faces with direct and averted gaze.

[Ab] Abstract:Most face processing research has investigated how we perceive faces presented by themselves, but we view faces everyday within a rich social context. Recent ERP research has demonstrated that context cues, including self-relevance and valence, impact electrocortical and emotional responses to neutral faces. However, the time-course of these effects is still unclear, and it is unknown whether these effects interact with the face gaze direction, a cue that inherently contains self-referential information and triggers emotional responses. We primed direct and averted gaze neutral faces (gaze manipulation) with contextual sentences that contained positive or negative opinions (valence manipulation) about the participants or someone else (self-relevance manipulation). In each trial, participants rated how positive or negative, and how affectively aroused, the face made them feel. Eye-tracking ensured sentence reading and face fixation while ERPs were recorded to face presentations. Faces put into self-relevant contexts were more arousing than those in other-relevant contexts, and elicited ERP differences from 150-750 ms post-face, encompassing EPN and LPP components. Self-relevance interacted with valence at both the behavioural and ERP level starting 150 ms post-face. Finally, faces put into positive, self-referential contexts elicited different N170 ERP amplitudes depending on gaze direction. Behaviourally, direct gaze elicited more positive valence ratings than averted gaze during positive, self-referential contexts. Thus, self-relevance and valence contextual cues impact visual perception of neutral faces and interact with gaze direction during the earliest stages of face processing. The results highlight the importance of studying face processing within contexts mimicking the complexities of real world interactions.

[Ab] Abstract:Purpose: Dietary factors are one of the main causes of urolithiasis. However, little research has evaluated dietary factors related to urolithiasis in Korea. We investigated the various dietary risk factors for urinary stone formation in Korean people. Materials and Methods: We conducted a prospective case-control pilot study. A total of 27 patients newly diagnosed with urolithiasis and 20 applicants without urolithiasis were designated as the patients and the control group, respectively. A face-to-face survey was carried out using a food-frequency questionnaire. After adjustment for physical activity level and total energy intake, multivariate logistic regression models were applied to search for risk factors for urolithiasis. Results: There were no significant differences between the two groups in gender, age, body mass index, family history, or total energy intake. The physical activity level of the control group was significantly higher than that of the patients (p=0.012). The results of the multivariate logistic regression model demonstrated that intake of carbohydrate (odds ratio [OR], 1.055; 95% confidence interval [CI], 1.012-1.099), protein (OR, 1.101; 95% CI, 1.001-1.211), and cereals (OR, 1.012; 95% CI, 1.002-1.023) could increase the risk for urolithiasis. Conclusions: A higher intake of carbohydrate, protein, and cereal may increase the risk of urinary stone formation among Korean people.

[Ab] Abstract:Monolayer transition metal dichalcogenides (TMDs) have become essential two-dimensional materials for their perspectives in engineering next-generation electronics. For related applications, the controlled growth of large-area uniform monolayer TMDs is crucial, while it remains challenging. Herein, we report the direct synthesis of 6-inch uniform monolayer molybdenum disulfide on the solid soda-lime glass, through a designed face-to-face metal-precursor supply route in a facile chemical vapor deposition process. We find that the highly uniform monolayer film, with the composite domains possessing an edge length larger than 400 m, can be achieved within a quite short time of 8 min. This highly efficient growth is proven to be facilitated by sodium catalysts that are homogenously distributed in glass, according to our experimental facts and density functional theory calculations. This work provides insights into the batch production of highly uniform TMD films on the functional glass substrate with the advantages of low cost, easily transferrable, and compatible with direct applications.

[Ab] Abstract:Quinones, which are ubiquitous in nature, can act as sustainable and green electrode materials but face dissolution in organic electrolytes, resulting in fast fading of capacity and short cycle life. We report that quinone electrodes, especially calix[4]quinone (C4Q) in rechargeable metal zinc batteries coupled with a cation-selective membrane using an aqueous electrolyte, exhibit a high capacity of 335 mA h g with an energy efficiency of 93% at 20 mA g and a long life of 1000 cycles with a capacity retention of 87% at 500 mA g . The pouch zinc batteries with a respective depth of discharge of 89% (C4Q) and 49% (zinc anode) can deliver an energy density of 220 Wh kg by mass of both a C4Q cathode and a theoretical Zn anode. We also develop an electrostatic potential computing method to demonstrate that carbonyl groups are active centers of electrochemistry. Moreover, the structural evolution and dissolution behavior of active materials during discharge and charge processes are investigated by operando spectral techniques such as IR, Raman, and ultraviolet-visible spectroscopies. Our results show that batteries using quinone cathodes and metal anodes in aqueous electrolyte are reliable approaches for mass energy storage.

[Ti] Title:The left frontal cortex supports reserve in aging by enhancing functional network efficiency.

[Ab] Abstract:BACKGROUND: Recent evidence derived from functional magnetic resonance imaging (fMRI) studies suggests that functional hubs (i.e., highly connected brain regions) are important for mental health. We found recently that global connectivity of a hub in the left frontal cortex (LFC connectivity) is associated with relatively preserved memory abilities and higher levels of protective factors (education, IQ) in normal aging and Alzheimer's disease. These results suggest that LFC connectivity supports reserve capacity, alleviating memory decline. An open question, however, is why LFC connectivity is beneficial and supports memory function in the face of neurodegeneration. We hypothesized that higher LFC connectivity is associated with enhanced efficiency in connected major networks involved in episodic memory. We further hypothesized that higher LFC-related network efficiency predicts higher memory abilities. METHODS: We assessed fMRI during a face-name association learning task performed by 26 healthy, cognitively normal elderly participants. Using beta-series correlation analysis, we computed task-related LFC connectivity to key memory networks, including the default mode network (DMN) and dorsal attention network (DAN). Network efficiency within the DMN and DAN was estimated by the graph theoretical small-worldness statistic. We applied linear regression analyses to test the association between LFC connectivity with the DMN/DAN and small-worldness of these networks. Mediation analysis was applied to test LFC connectivity to the DMN and DAN as a mediator of the association between education and higher DMN and DAN small-worldness. Last, we tested network small-worldness as a predictor of memory performance. RESULTS: We found that higher LFC connectivity to the DMN and DAN during successful memory encoding and recognition was associated with higher small-worldness of those networks. Higher task-related LFC connectivity mediated the association between education and higher small-worldness in the DMN and DAN. Further, higher small-worldness of these networks predicted better performance in the memory task. CONCLUSIONS: The present results suggest that higher education-related LFC connectivity to key memory networks during a memory task is associated with higher network efficiency and thus enhanced reserve of memory abilities in aging.

[Ab] Abstract:BACKGROUND: More and more concerns have been arisen about the ability of new medical graduates to meet the demands of today's practice environment. In this study, we wanted to develop a valid, reliable and standardized assessment tool for evaluating the basic microsurgical skills of residents in a microsurgery laboratory, to get them well prepared before entering the surgical realm of ophthalmology. METHODS: Twenty-three experts who have teaching experience reviewed the assessment scale. Constructive comments were incorporated to ensure face and content validity. Twenty-one attendings from different specialties then graded eight corneal rupture suturing videos with the scale to investigate interrater reliability. Fourteen of them graded the same videos 3 months later to investigate intrarater reliability (repeatability). RESULTS: A total of 280 assessment scales were completed. All the ICC values of interrater reliability were greater than 0.8 with 75% data greater than 0.9 (range 0.860-0.976). All the ICC values of intrarater reliability (repeatability) were also greater than 0.8 with 63% data greater than 0.9 (range 0.833-0.954). CONCLUSIONS: The assessment scale we developed is valid and reliable. This tool could be useful to ensure that junior residents achieve a certain level of microsurgical technique in a laboratory environment before training in the operation room. Hopefully, this tool will provide a structured template for other residency programs to assess their residents for basic microsurgical skills.

[Ab] Abstract:Previously, we have shown that people who have had one eye surgically removed early in life during visual development have enhanced sound localization [1] and lack visual dominance, commonly observed in binocular and monocular (eye-patched) viewing controls [2]. Despite these changes, people with one eye integrate auditory and visual components of multisensory events optimally [3]. The current study investigates how people with one eye perceive the McGurk effect, an audiovisual illusion where a new syllable is perceived when visual lip movements do not match the corresponding sound [4]. We compared individuals with one eye to binocular and monocular viewing controls and found that they have a significantly smaller McGurk effect compared to binocular controls. Additionally, monocular controls tended to perceive the McGurk effect less often than binocular controls suggesting a small transient modulation of the McGurk effect. These results suggest altered weighting of the auditory and visual modalities with both short and long-term monocular viewing. These results indicate the presence of permanent adaptive perceptual accommodations in people who have lost one eye early in life that may serve to mitigate the loss of binocularity during early brain development.
