Social decision making in binge drinking: An exploration through moral dilemmas.

The continuum hypothesis proposes that binge drinking and severe alcohol use disorder (SAUD) share qualitatively similar cognitive and emotional impairments. In SAUD, these deficits have a demonstrated impact on social decision making, resulting in a utilitarian bias. Namely, when confronted with moral dilemmas, patients with SAUD tend to focus on the consequences of their actions rather than on social norms. However, social decision-making abilities remain unexplored in binge drinking. We offered the first insights on the generalization of the continuum hypothesis to social decision making, through a multinomial processing tree model applied to moral dilemmas, the "CNI model" of moral decision making. We compared 35 binge drinkers (20 females) and 36 light drinkers (21 females) on a battery of 48 moral dilemmas involving interpersonal relations from the CNI model, through multinomial modeling analyses. In each dilemma, participants were asked if they would perform the described action, generating individual scores for sensitivity to consequences, sensitivity to norms, and inaction tendency. The statistical model related to the CNI approach fits the data well. Binge drinkers and controls did not differ regarding their sensitivity to consequences nor their sensitivity to moral norms, and both groups displayed an equal inaction tendency in response to moral dilemmas. We provided insights to better understand the specific (socio)cognitive domains impaired in subclinical populations with alcohol use disorder. We showed preserved social decision making in binge drinking, which suggests that the continuum hypothesis documented for classical neurocognitive functions does not extend to complex social abilities.

Non-surgical treatment of residual periodontal pockets using sodium hypochlorite/amino acid gel and cross-linked hyaluronic acid—a 9-month pilot randomized controlled clinical trial

ObjectivesThis pilot randomized controlled clinical trial compares the clinical outcome obtained in persistent periodontal pockets during 9-month follow-up of supportive periodontal step 4 treatment performed by either combining subgingival instrumentation with adjunctively used sodium hypochlorite/amino acid gel and crosslinked hyaluronic acid (xHyA) or subgingival instrumentation alone.Materials and methodsStudy protocol is registered under NCT06438354 at Clinicaltrials.gov. Patients seeking further therapy after completed step 2 non-surgical periodontal treatment underwent either repeated subgingival instrumentation with adjunctive application of sodium hypochlorite/amino acid gel and crosslinked hyaluronic acid (group A) or repeated subgingival instrumentation alone (group B). One calibrated investigator performed the treatment sequence in both groups accordingly. Subgingival instrumentation of the residual pockets was carried out under local anaesthesia using hand- and ultrasonic instruments, as well as air polishing in both groups. Patients were instructed to continue oral hygiene without any restriction. At 3-month re-evaluation treatment was repeated accordingly at sites with persistent 5 mm probing depth and BoP + . Clinical attachment level (CAL), pocket probing depth (PPD), gingival recession (GR), and bleeding on probing (BoP) were recorded at baseline (T1), 3- (T2) and 9-month (T3) post-op, with CAL as a primary outcome measure.ResultsIn total 52 patients (20 females and 32 males, mean age 58.4 ± 2.4 years) presenting with 1448 sites which required further periodontal treatment were enrolled. Both groups exhibited homogeneity in terms of age, gender, smoking habit, initial number of sites, and BOP. At 9-month evaluation, PD reduction and CAL gain showed significant differences between the test and control group, favouring the adjunctive treatment. GR tended to exhibit more recovery in the test group compared to the control group. Although BOP frequency effectively reduced in both groups, there was no statistically significant difference between the two groups.ConclusionWithin the limits of the study, the present data indicates that, during subgingival instrumentation of persistent pockets, the adjunctive usage of sodium hypochlorite/amino acid gel and xHyA sufficiently improves the clinical outcomes. The continuous improvement of CAL in association with the GR scores observed in group A, indicates that sites subjected to adjunctive treatment may indicate a tendency for a regenerative response to treatment within the 9-month follow-up period.

A shared temporal window of integration across cognitive control and reinforcement learning paradigms: A correlational study.

Cognitive control refers to the ability to override prepotent response tendencies to achieve goal-directed behavior. On the other hand, reinforcement learning refers to the learning of actions through feedback and reward. Although cognitive control and reinforcement learning are often viewed as opposing forces in driving behavior, recent theories have emphasized possible similarities in their underling processes. With this study, we aimed to investigate whether a similar time window of integration could be observed during the learning of control on the one hand, and the learning rate in reinforcement learning paradigms on the other. To this end, we performed a correlational analysis on a large public dataset (n = 522) including data from two reinforcement learning tasks, i.e., a probabilistic selection task and a probabilistic Wisconsin Card Sorting Task (WCST), and data from a classic conflict task (i.e., the Stroop task). Results showed expected correlations between the time scale of control indices and learning rate in the probabilistic WCST. Moreover, the learning-rate parameters of the two reinforcement learning tasks did not correlate with each other. Together, these findings suggest a reliance on a shared learning mechanism between these two traditionally distinct domains, while at the same time emphasizing that value updating processes can still be very task-specific. We speculate that updating processes in the Stroop and WCST may be more related because both tasks require task-specific updating of stimulus features (e.g., color, word meaning, pattern, shape), as opposed to stimulus identity.

Validation of the dispositional adult hyperfocus questionnaire (AHQ-D)

Hyperfocus (HF), or intense, deep concentration on a task, has gained significant research attention in recent years, particularly in regard to clinical populations such as Attention-Deficit/Hyperactivity Disorder (ADHD). The present work aims to provide validation of the 12-item dispositional adult hyperfocus questionnaire (AHQ-D) as a quantitative metric of HF in adults. We preregistered the study design and hypotheses. We administered the AHQ-D and several additional questionnaires to 347 adults (mean ± SD age: 33 ± 11 years; 47% female). Exploratory factor analysis revealed high factor loadings (0.57–0.81) on a single HF factor; item response theory analysis suggested that the questionnaire items had high discrimination and covered a wide range of responses; and we report strong internal consistency metrics (Cronbach’s alpha 0.93, mean split-half reliability 0.93). Replicating our previous work, HF was positively correlated with Conners’ Adult ADHD Rating Scale (CAARS) scores (r(345) = 0.53), suggesting that HF may be related to ADHD traits (though in this sample we did not specifically recruit individuals with ADHD). The AHQ-D demonstrated the hypothesized convergent validity; HF on the AHQ-D was positively correlated with HF measured using a different HF scale (r(344) = 0.69), as well as flow (r(345) = 0.12) and mind wandering (r(345) = 0.39) scores. AHQ-D HF scores showed a weak negative correlation with grit (r(345) = − 0.29). Though there was a weak negative correlation between HF and social desirability response tendency (r(345) = − 0.24), suggesting that those who care more about what others think may report less HF, there was no relationship between HF and extrasensory perception beliefs (r(345) = 0.01), suggesting that participants were not simply biased in their response tendencies. Taken together, we demonstrate strong scale metrics for the AHQ-D, the expected convergent validity, and a general lack of response bias, in addition to replicating our previous association of HF with ADHD traits. We suggest that the AHQ-D can be confidently used in future work as a valid way to measure HF in adults.

Impact of state and trait emotion regulation on daily emotional exhaustion among Korean school counsellors.

School counsellors in South Korea face significant emotional exhaustion due to their challenging occupational environment. Previous studies have shown that cognitive reappraisal (CR) reduces emotional exhaustion, whereas expressive suppression (ES) increases it. However, these findings predominantly rely on trait questionnaires within cross-sectional approaches, overlooking the dynamic nature of emotion regulation (ER) strategy selection. Individuals may choose strategies that deviate from their general tendencies based on situational demands. There is limited empirical knowledge regarding the interaction between trait and state regulation strategies and their influence on exhaustion. Utilizing the strategy-situation fit hypothesis, this study examines the context-specific effects of ER strategies, considering both situational contexts and individual response tendencies. A multilevel analysis was performed to examine the influence of state and trait ER strategies on daily emotional exhaustion. A daily diary study was conducted for 5days with 111 Korean school counsellors. Daily CR was associated with lower daily exhaustion and daily ES predicted higher daily exhaustion. Contrastingly, none of the trait ER strategies had an impact on daily exhaustion, but the trait level of both strategies significantly moderated the relationship between daily CR and exhaustion. The positive impact of daily CR was more pronounced in school counsellors who often utilized suppression strategies, and this impact was also evident in trait reappraisal. Re-evaluating daily emotions instead of suppressing them may assist in coping with emotional exhaustion caused by work. The effectiveness of these strategies may vary based on an individual's inclination to regulate emotions as state and trait. ER may aid in implementing preventive interventions for school counsellors experiencing emotional exhaustion.

Personal control and cognitive flexibility: Does uncontrollability reduce flexible shifting of attention?

Acting and learning in unpredictable and volatile environments requires cognitive flexibility. However, the ability to flexibly adapt to the changing task environment can be reduced when people experience uncontrollability due to exposure to action – outcome non-contingency. In this research, we propose that flexible shifting of attention is affected by experiences of uncontrollability. In two studies, a lack of control was experimentally induced and subsequently cognitive flexibility was assessed either with a Wisconsin Card Sorting Task (Study 1) or a cognitive set-shifting paradigm (Study 2). Results showed a reduced tendency to flexibly shift attention and to overcome dominant response tendencies amongst participants who experienced uncontrollability. Modulation of the stability-flexibility balance by situationally induced experiences of uncontrollability is discussed.

"My baby is ready to learn"-The role of infant pointing in redirecting maternal responses to be more informative.

Caregivers may perceive pointing as an indication of infants' readiness to learn, thereby increasing their tendency to label objects regardless of the infant's gesture type and context. This was investigated in this study by tracking 35 infants at home at the ages of 11 and 13months and observing their interactions with their mothers during object manipulation. We focused on four types of communicative gestures: typical giving gestures, gestures contingent on exploration, gestures contingent on play, and pointing. We analyzed maternal response tendencies, including affirmation, naming, discourse, and pretense. The results revealed that when infants reached the age of 13months, they tripled their pointing production; in turn, the maternal response changed entirely, with naming becoming the preferred response to all types of gestures. Furthermore, when infants were 13months old and offered an object contingent on play acts, mothers increased their pretense acts sevenfold. Based on the most informative responses to infants among those examined, we argue that an increase in the number of pointing gestures may gradually be associated with the establishment of the maternal perception that an infant is ready to learn and a subsequent increase in naming and pretense production by the mother.

Approach-Avoidance Training: Exploring the Role of Action Identification Processes

Approach-Avoidance Training (AAT) aims to modify evaluations and behaviors towards specific stimuli through repetitive engagement in approach and avoidance behaviors. The current research investigates whether training conditions that promote action identification at the level of approach-avoidance movements, rather than at the level of behavioral actions effecting these movements, are more effective in changing evaluative reactions towards fictitious social groups. In two experiments (total N = 411), participants directed a computerized manikin, symbolizing the self, towards one group and away from another. Following the training, participants liked the approached group more than the avoided group in both explicit and indirect attitude measures. These changes in liking were not influenced by training conditions that enabled consistent key presses throughout the task (facilitating action identification at the motoric level) and those that necessitated alternating key presses (promoting action identification at the approach-avoidance level). Furthermore, changes in liking were unrelated to changes in AA-related response tendencies as assessed with a separate response task. It is concluded that the manikin task utilized for AAT is robust against task variants that facilitate action identification at the motor level, especially when the training instructions are clear about which stimuli should be approached and avoided. Insights for the practical application of AAT are discussed.

Are we afraid of the woods? – An investigation of the implicit and explicit fear reactions to forests

The beneficial effects of nature exposure have been repeatedly documented and encourage frequent and regular contact with nature and especially highlight forests. However, in human history, forests have also been associated with negative emotions such as fear and were seen as dangerous environments. While existing literature could demonstrate that natural environments can evoke fear, the focus was on the explicit perception. Given that research has shown the significance of additional implicit processes in fear-related behaviour, we aim to explore the presence of an implicit fear response to forests. Therefore, in an online study, we investigated the explicit and implicit fear reactions to forests by a Northern German sample of N = 256. Using three explicit measurements, we investigated fear and danger perception on a semantic and visual level of the stimulus category "forest" compared to the human-made urban green space "park" and the urban setting "house". Additionally, we assessed the unconscious response tendencies towards the forest within three implicit tasks: Subliminal Priming Procedure (SPP), Affect Misattribution Procedure (AMP) and Approach-Avoidance Task (AAT). Within the analyzed sample, the subliminally presented word forest evoked a stronger positive valence response compared to park (SPP). In contrast to houses, the forest showed a stronger approach and weaker avoidance tendency (AAT). At the same time, both the three explicit and one implicit measurement (AMP) showed a stronger fear perception of forests compared to parks or houses. Considering the increasingly utilised beneficial effects of nature in interventions, these findings should be acknowledged when implementing nature exposure in interventions and treatments.

Development of CNN-based sub-sonic speed vehicle body frame micro damage assessment technology using guided wave spectrogram images

Due to advancements in diagnostic technology, sub-sonic speed trains are subjected to significant fatigue stress on their bodies. This phenomenon can be considered a menace, leading to significant accidents on railways due to the tiny size of defects on the train bodies. In this research, a deep learning approach is employed to identify the initial damage status. The goal is to develop an evaluation technique for verifying an initial wall-thinning crack using frequency spectrogram images. The wall-thinning effects of 6.3 mm thick aluminum AL-2024 T6 plates, primarily used in frames and bodies, are confirmed through the frequency responses of guided waves. To verify the effects of wall thinning, both higher-order harmonic frequencies of guided waves and nonlinear ultrasonic techniques are simultaneously used. To identify the tendency of frequency response, frequency spectrogram images, illustrated by short-time Fourier transforming analysis, are chosen. For training the detection system using the Region-based Convolutional Neural Network (R-CNN), spectrogram images are generated for wall-thinning steps with an increment of 0.2 mm (3% of the total thickness). The ResNet-50 is employed in the convolutional layer of the R-CNN engine to address the issue of gradient vanishing. The results of this research indicate that the depth of wall thinning in the plates can be identified. Based on the R-CNN training set, the initial wall-thinning failure can be verified with reliable accuracy.

Reducing problematic pornography use with imaginal retraining-A randomized controlled trial.

Problematic pornography use (PPU) can be a manifestation of compulsive sexual behavior disorder (CSBD). Studies investigating PPU confirm approach-avoidance tendencies in response to pornographic stimuli in this population. This study show indications of the significance of the efficacy of imaginal retraining, a variant of approach bias modification, as an intervention for PPU. A total of 274participants (86.5% male; mean age = 30.65, SD = 10.13) with self-reported PPU were randomized to imaginal retraining (instruction video) or a waitlist control group. Assessments were conducted online at baseline and after the six-week intervention period. The primary outcome was a reduction in problematic pornography use. Compulsive sexual behavior, sexual desire, depressiveness, and satisfaction with the intervention served as secondary outcomes. Retention was low (51.7%), but comparable between groups. The retraining was performed at least once a week (the per-protocol [PP] criterion) by 51.4% of participants. The PP analyses of 111 participants showed a significant reduction in problematic pornography use (primary outcome) in the intervention compared to the control group. The intention-to-treat analyses (ITT), however, did not corroborate this result. Despite low adherence, participants rated their satisfaction with the intervention positively. Imaginal retraining can function as a low-threshold self-help intervention for PPU to overcome help-seeking barriers and may reduce PPU in a subgroup of users. Low adherence limits the results of this trial. Given the need for low-threshold interventions for PPU and/or CSBD, further research should focus on increasing adherence and should evaluate retraining for clinical groups. Modifications to augment efficacy are suggested.

Subthalamic control of impulsive actions: insights from deep brain stimulation in Parkinson's disease.

Control of actions allows adaptive, goal-directed behaviour. The basal ganglia, including the subthalamic nucleus, are thought to play a central role in dynamically controlling actions through recurrent negative feedback loops with the cerebral cortex. Here, we summarize recent translational studies that used deep brain stimulation to record neural activity from and apply electrical stimulation to the subthalamic nucleus in people with Parkinson's disease. These studies have elucidated spatial, spectral and temporal features of the neural mechanisms underlying the controlled delay of actions in cortico-subthalamic networks and demonstrated their causal effects on behaviour in distinct processing windows. While these mechanisms have been conceptualized as control signals for suppressing impulsive response tendencies in conflict tasks and as decision threshold adjustments in value-based and perceptual decisions, we propose a common framework linking decision-making, cognition and movement. Within this framework subthalamic deep brain stimulation can lead to suboptimal choices by reducing the time that patients take for deliberation before committing to an action. However, clinical studies have consistently shown that the occurrence of impulse control disorders is reduced, not increased, after subthalamic deep brain stimulation surgery. This apparent contradiction can be reconciled when recognizing the multifaceted nature of impulsivity, its underlying mechanisms and modulation by treatment. While subthalamic deep brain stimulation renders patients susceptible to making decisions without proper forethought, this can be disentangled from effects related to dopamine comprising sensitivity to benefits vs. costs, reward delay aversion and learning from outcomes. Alterations in these dopamine-mediated mechanisms are thought to underlie the development of impulse control disorders, and can be relatively spared with reduced dopaminergic medication after subthalamic deep brain stimulation. Together, results from studies using deep brain stimulation as an experimental tool have improved our understanding of action control in the human brain and have important implications for treatment of patients with Neurological disorders.

Lupus progression deteriorates oogenesis quality in MRL/lpr mice.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by the activation of the immune response against self antigens. Numerous reproductive complications, including reduced birth rate and complications for the mother and the fetus during pregnancy, have been observed in women with SLE. In the present study, we aimed to investigate the effect of SLE development on oocyte meiosis in lupus-prone mice. Lupus-prone MRL/lpr mice were used for the experiments: disease-free (4weeks of age) and sick (20weeks of age, virgin and postpartum). The immune response was monitored by flow cytometry, ELISpot, ELISA, and histology. Oocytes were analyzed by fluorescence microscopy based on chromatin, tubulin, and actin structures. The lupus-prone MRL/lpr mice developed age-dependent symptoms of SLE with increased levels of various autoantibodies, proteinuria, and renal infiltrates and a tendency for the immune response to worsen with changes in cell populations and the cytokine profile. The number and quality of oocytes were also affected, and the successful pregnancy rate of MRL/lpr mice was limited to only 60%. Isolated oocytes showed severe structural changes in all studied groups. Systemic alterations in immune homeostasis in SLE affect the quality of developing oocytes, which is evident from a young age. The data obtained is in line with the trend of reduced fertility in lupus-prone MRL/lpr mice. The phenomenon can be explained by changes in the microenvironment of the relevant organs and close connection between ovulation and inflammatory processes.

Evaluating ChatGPT's effectiveness and tendencies in Japanese internal medicine.

ChatGPT, a large-scale language model, is a notable example of AI's potential in health care. However, its effectiveness in clinical settings, especially when compared to human physicians, is not fully understood. This study evaluates ChatGPT's capabilities and limitations in answering questions for Japanese internal medicine specialists, aiming to clarify its accuracy and tendencies in both correct and incorrect responses. We utilized ChatGPT's answers on four sets of self-training questions for internal medicine specialists in Japan from 2020 to 2023. We ran three trials for each set to evaluate its overall accuracy and performance on nonimage questions. Subsequently, we categorized the questions into two groups: those ChatGPT consistently answered correctly (Confirmed Correct Answer, CCA) and those it consistently answered incorrectly (Confirmed Incorrect Answer, CIA). For these groups, we calculated the average accuracy rates and 95% confidence intervals based on the actual performance of internal medicine physicians on each question and analyzed the statistical significance between the two groups. This process was then similarly applied to the subset of nonimage CCA and CIA questions. ChatGPT's overall accuracy rate was 59.05%, increasing to 65.76% for nonimage questions. 24.87% of the questions had answers that varied between correct and incorrect in the three trials. Despite surpassing the passing threshold for nonimage questions, ChatGPT's accuracy was lower than that of human specialists. There was a significant variance in accuracy between CCA and CIA groups, with ChatGPT mirroring human physician patterns in responding to different question types. This study underscores ChatGPT's potential utility and limitations in internal medicine. While effective in some aspects, its dependence on question type and context suggests that it should supplement, not replace, professional medical judgment. Further research is needed to integrate Artificial Intelligence tools like ChatGPT more effectively into specialized medical practices.

251 Effects of feeding increasing levels of dimethylglycine (DMG) on growth performance, livability, and carcass characteristics of commercial finishing pigs

Abstract This study aimed to evaluate the impact of increasing dietary levels of 78% sodium dimethylglycine (DMG) on growth performance, livability, and carcass characteristics of commercial finishing pigs. A total of 1,115 mixed-sex finishing pigs [initial body weight (BW) = 70.1 ± 1.8 kg] were housed in pens with 25 to 27 pigs per pen. Pens within block were assigned randomly to one of four dietary treatments containing 0 (Control), 0.25 (DMG_0.25), 0.5 (DMG_0.5) or 1.0 (DMG_1.0) g DMG/kg of feed with 11 replicates per treatment. This experiment extended over an 8-wk period until pigs were harvested at 125.4 ± 0.8 kg of BW. Data were analyzed using the MIXED procedure of SAS, and preplanned orthogonal contrasts were conducted to evaluate pairwise comparisons as well as linear and quadratic effects related to the increased levels of DMG. While no linear effect was observed, there was a tendency for a quadratic response in closeout feed efficiency (G/F; P = 0.08) and the percentage of pigs with morbidity (P = 0.06), with the most favorable responses found in pigs fed DMG_0.25 (Table 1). Pairwise comparisons between Control and DMG_0.25 treatments suggest that pigs receiving DMG_0.25 showed a 6% increase in closeout average daily gain (ADG; 1.01 vs. 0.95 kg/d; P = 0.02) and a 4% increase in closeout G/F (0.337 vs. 0.324; P = 0.05) compared with those fed Control diet. Furthermore, DMG supplemented at 0.25 g/kg tended to be associated with decreased mortality (P = 0.08), reduced morbidity (P = 0.09) and more pigs sold to the primary market (P = 0.10) compared with Control. In contrast, dietary supplementation of greater concentrations of DMG at 0.5 and 1.0 g/kg were not different compared with Control (P > 0.10). Carcass characteristics, including hot carcass weight, carcass yield, fat depth, loin depth, and fat-free carcass lean, were not different among treatments. The findings of this study suggest dietary supplementation of DMG at 0.25 g/kg of feed enhanced growth performance and livability in finishing pigs. However, feeding greater concentrations of DMG, up to 1.0 g/kg of feed, did not produce different outcomes compared with Control. These results indicate the potential benefits of DMG at specific inclusion rate in optimizing the production and health of finishing pigs.

Why is Chemistry Education? Exploring the Motivation of Student Choices

Learning motivation is critical to educational success, influencing students' engagement, persistence, and overall performance. Despite its importance, motivation determines students' choices for future careers and struggles in participating in learning activities. The aim was to characterize students' chemistry learning motivation in detail using the Academic Motivation Scale - Chemistry (AMS-Chemistry). This study employs a descriptive qualitative research design. The qualitative approach allows an in-depth exploration of personal experiences and perceptions of learning motivation in chemistry education. The AMS-Chemistry instrument consists of 28 statement items that measure aspects of amotivation, three types of extrinsic motivation, and three types of intrinsic motivation. The results show that the motivation profile to learn Chemistry in Chemistry Education students using the AMS-Chemistry instrument on the amotivation subscale tends to disagree (55,46%). On intrinsic motivation, the to know subscale tends to agree (65,80%) strongly, the to accomplish subscale has a high score on strongly agree (48,85%) responses, and the to experience subscale tends to respond strongly agree (35,34%). Extrinsic motivation includes the external regulation subscale tending to strongly agree (55,17%) and the introjected regulation subscale having a high score on strongly agree (62,36%) responses. The identified regulation subscale has a strongly agree (68,97%) response tendency.

Personality assessment in nursing home residents with mental and physical multimorbidity: two informant perspectives.

In older patients with mental and physical multimorbidity (MPM), personality assessment is highly complex. Our aim was to examine personality traits in this population using the Hetero-Anamnestic Personality questionnaire (HAP),and to compare the premorbid perspective of patients' relatives (HAP) with the present-time perspective of nursing staff (HAP-t). Cross-sectional. Dutch gerontopsychiatric nursing home (GP-NH) units. Totally, 142 GP-NH residents with MPM (excluding dementia). NH norm data of the HAP were used to identify clinically relevant premorbid traits. Linear mixed models estimated the differences between HAP and HAP-t trait scores (0-10). Agreement was quantified by intraclass correlation coefficients (ICCs). All HAP-HAP-t analyses were corrected for response tendency (RT) scores (-10-10). 78.4% of the patients had at least one premorbid maladaptive trait, and 62.2% had two or more. Most prevalent were: "disorderly" (30.3%), "unpredictable/impulsive" (29.1%) and "vulnerable" (27.3%) behavior. The RT of relatives appeared significantly more positive than that of nursing staff (+1.8, 95% CI 0.6-2.9, p = 0.002). After RT correction, the traits "vulnerable", "perfectionist" and "unpredictable/impulsive" behavior scored higher on the HAP than HAP-t (respectively +1.2, 95% CI 0.6-1.7, p < 0.001; +2.1, 95% CI 1.3-2.8, p < 0.001; +0.6, 95% CI 0.1-1.1, p = 0.013), while "rigid" behavior scored lower (-0.7, 95% CI -1.3 to -0.03, p = 0.042). Adjusted ICCs ranged from 0.15 to 0.58. Our study shows high percentages of premorbid maladaptive personality traits, which calls for attention on personality assessment in MPM NH residents. Results also indicate that the HAP and HAP-t questionnaires should not be used interchangeably for this patient group in clinical practice.

Constituents of stable commensal microbiota imply diverse colonic epithelial cell reactivity in patients with ulcerative colitis

BackgroundDespite extensive research on microbiome alterations in ulcerative colitis (UC), the role of the constituent stable microbiota remains unclear.ResultsThis study, employing 16S rRNA-gene sequencing, uncovers a persistent microbial imbalance in both active and quiescent UC patients compared to healthy controls. Using co-occurrence and differential abundance analysis, the study highlights microbial constituents, featuring Phocaeicola, Collinsella, Roseburia, Holdemanella, and Bacteroides, that are not affected during the course of UC. Co-cultivation experiments, utilizing commensal Escherichia coli and Phocaeicola vulgatus, were conducted with intestinal epithelial organoids derived from active UC patients and controls. These experiments reveal a tendency for a differential response in tight junction formation and maintenance in colonic epithelial cells, without inducing pathogen recognition and stress responses, offering further insights into the roles of these microorganisms in UC pathogenesis. These experiments also uncover high variation in patients’ response to the same bacteria, which indicate the need for more comprehensive, stratified analyses with an expanded sample size.ConclusionThis study reveals that a substantial part of the gut microbiota remains stable throughout progression of UC. Functional experiments suggest that members of core microbiota – Escherichia coli and Phocaeicola vulgatus – potentially differentially regulate the expression of tight junction gene in the colonic epithelium of UC patients and healthy individuals.

Serum proteomic profiling of precancerous gastric lesions and early gastric cancer reveals signatures associated with systemic inflammatory response and metaplastic differentiation.

The noninvasive detection technique using serum for large-scale screening is useful for the early diagnosis of gastric cancer (GC). Herein, we employed liquid chromatography mass spectrometry to determine the serum proteome signatures and related pathways in individuals with gastric precancerous (pre-GC) lesions and GC and explore the effect of Helicobacter pylori (H. pylori) infection. Differentially expressed proteins in GC and pre-GC compared with non-atrophic gastritis (NAG) group were identified. APOA4, a protein associated with metaplastic differentiation, and COMP, an extracellular matrix protein, were increased in the serum of patients with pre-GC lesions and GC. In addition, several inflammation-associated proteins, such as component C3, were decreased in the GC and pre-GC groups, which highlight a tendency for the inflammatory response to converge at the gastric lesion site during the GC cascade. Moreover, the abundance of proteins associated with oxidant detoxification was higher in the GC group compared with that in the NAG group, and these proteins were also increased in the serum of the H. pylori-positive GC group compared with that in the H. pylori-negative GC patients, reflecting the importance of oxidative stress pathways in H. pylori infection. Collectively, the findings of this study highlight pathways that play important roles in GC progression, and may provide potential diagnostic biomarkers for the detection of pre-GC lesions.

Resilience and Rights: Responding to Crime through a Human Rights Lens

Recently, a well-deserved attention was brought to the intersection between crime response and resilience as a human right. The paper explores the resilience concept within the domain of human rights, spotting the light on critical tendencies in crime and responses and reviewing the ‘human rights’ and ‘resilience’ perspectives. Shaping the principles and approaches of both, it implies that resilience and human rights perspectives should be applied simultaneously in criminal justice. The source provides an in-depth legal research analysis that helps to better understand the value and implications of such an approach. Overall, the notion defends the holistic and rights-centred approaches to crime processing.
