ABSTRACT

Implicit statistical learning of a sequence of information is determined by several factors, including the number of repetitions of the sequence and the distance between each repetition. In the present study, we used a Hebbian version of the lexical decision task in which participants must decide whether the items presented in the center of a computer screen are words or non-words. Unbeknownst to the participants, a sequence of three words is presented and repeated in the same order several times (30 times). For each group of participants, we manipulated the distance between each repetition of the triplet of words by inserting the same number of filler items (i.e., on average, 4, 7, 10, 20, 30 or 60). Our results show that learning of the sequence is still possible at large distances (60 filler items apart) and that the learning rate best fit a power law. Furthermore, the processing speed of the words in the repeated triplet is differentially affected by the distance between repetitions. These data thus provide novel constraints for current models of implicit statistical learning.

ABSTRACT

INTRODUCTION: Recent research suggests that body contouring surgeries may reduce benzodiazepine (BNZ) use in patients with anxiety or depressive disorders. This study explores whether similar benefits occur in women with lipedema-a chronic adipose disorder causing pain, limited mobility, and psychological distress-who are often prescribed BNZ.

MATERIALS AND METHODS: We conducted a retrospective observational study on 100 adult female patients with Stage I-III lipedema undergoing tumescent or water-assisted liposuction between 2019 and 2024. All participants were on stable BNZ therapy for at least six months before surgery. The primary outcome was BNZ usage at six months postoperatively. Secondary outcomes included anxiety (GAD-7), pain (VAS), sleep quality (PSQI), and body image (BODY-Q) and assessed pre- and post-surgery using validated instruments.

DISCUSSION: At six months, 77% of patients reduced or discontinued BNZ (32% stopped entirely), with average daily dosage decreasing from 3.2 ± 1.1 to 1.4 ± 1.2 mg (p < 0.001). Statistically significant improvements were also observed in anxiety, pain, sleep quality, and body image (all p < 0.001). Reductions in BNZ use correlated with improvements in pain (r = 0.56), anxiety (r = 0.47), and body image (r = – 0.52). Only minor complications occurred (8%), and no major adverse events were reported.

CONCLUSION: Liposuction for lipedema not only improves physical symptoms but also supports psychological recovery, reducing dependence on benzodiazepines. These findings highlight the potential of surgical treatment as part of an integrated approach to managing chronic conditions with both somatic and mental health components. Further research is needed to confirm long-term effects and underlying mechanisms.

ABSTRACT

We present a new set of English property norms for 260 object concepts based on the standardized Snodgrass and Vanderwart (1980) picture set. For each object, 100 participants provided a basic-level label (dog), a superordinate category (animal), and three features (bark, tail, fur), yielding a dataset of 78,000 features. Our norms differ from other datasets in four important ways: they (1) probe basic-level information, (2) separate taxonomic and feature information, (3) use open-ended responses for natural descriptions, and (4) include a larger number of responses per object (100 vs. ~ 30 participants in other norms). We analyzed feature statistics such as frequency, distinctiveness, and co-occurrence, and contrasted our norms with those of McRae et al. (2005), CSLB (Devereux et al., 2014), and Hovhannisyan et al. (2021). Compared to picture-based norms, our data-derived from black-and-white line drawings-elicited more diverse features and aligned more closely with language-based norms, particularly CSLB. We assessed the generalizability of our norms using an object-property congruency task, where 144 participants judged whether properties (basic level, superordinate, and features) were related to objects. Objects were shown in three picture formats with increasing ecological validity: (1) colored line drawings, (2) realistic photographs, and (3) realistic photographs of objects in scenes. We then contrasted these data with those of Antal & de Almeida (2024) employing the original line-drawing set. Agreement rates for object-property pairs remained high across picture formats and property types. Bayesian inference revealed minimal variability in congruency judgments across picture formats, with responses tightly clustered around zero. Results show that our norms are generalizable to realistic visual stimuli. Norms are available at https://osf.io/c6brw/overview .

ABSTRACT

BACKGROUND: Trust in the medical profession is important for patient engagement, treatment adherence, and effective healthcare relationships; thus, a culturally appropriate patient-reported instrument for measuring this construct in Malaysia is needed. This study aimed to translate and culturally adapt the 11-item Trust in the Medical Profession scale (TIMP) into Malay and evaluate its psychometric properties in a Malaysian sample.

METHODS: A cross-sectional psychometric study was conducted among 376 Malaysian adults with prior COVID-19 care experience. Content validity was evaluated by a six-expert panel. Reliability was assessed using Cronbach’s alpha and McDonald’s omega. Structural validity was examined using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Convergent validity was evaluated through correlations with related constructs, namely the Skala Kepuasan Interaksi Perubatan (SKIP), the Malay Patient Measure of Safety-10 (M-PMOS-10), and the Malay version of the Multidimensional Scale of Perceived Social Support (MSPSS-M).

RESULTS: The mean TIMP score was 3.02 (SD = 0.94) on a 5-point scale. Content validity was strong (I-CVI = 0.83-1.00; S-CVI/Ave = 0.97; mean κ = 0.97). Reliability was excellent (α = 0.94, 95% CI [0.93, 0.95]; ω = 0.94, 95% CI [0.93, 0.95]). EFA supported one factor (KMO = 0.963; Bartlett’s χ²(55) = 2611.91, p < .001; first eigenvalue = 6.84, 62.1% variance) with loadings from 0.75 to 0.80. The one-factor CFA fit the data well (χ²(44) = 73.52, p = .003; CFI = 0.989; TLI = 0.986; RMSEA = 0.042 [90% CI 0.024-0.059]; SRMR = 0.023), with CR = 0.944 and AVE = 0.585. Convergent validity was supported by positive correlations with SKIP (r = .62, p < .001), M-PMOS-10 (r = .68, p < .001), and MSPSS-M (r = .16, p = .002).

CONCLUSIONS: The Malay TIMP demonstrated strong psychometric properties in this sample and provides initial evidence for assessing trust in the medical profession among Malay-speaking Malaysian adults. Further validation in broader community and clinical samples is warranted.

ABSTRACT

PURPOSE: We performed updated subgroup analyses of the EMERALD study to investigate efficacy, safety, and quality of life (QoL) in patients treated with eribulin (E) vs. either docetaxel (DTX) or paclitaxel (PTX).

METHODS: Patients with HER2+ locally advanced/metastatic breast cancer (LABC/MBC) were randomized to receive E or taxane (T) (physician’s choice of DTX or PTX; declared in advance at registration) in 21-day cycles, each combined with trastuzumab + pertuzumab. Survival outcomes, treatment patterns, antitumor efficacy, safety, and QoL were examined.

RESULTS: The intention-to-treat (and safety) populations comprised 224 (224) patients who received E, 186 (184) who received DTX, and 36 (34) who received PTX. Baseline characteristics were balanced. Progression-free survival (E vs. DTX: 14.0 vs. 13.1 months; hazard ratio [HR], 0.94 [95% CI, 0.74-1.21]; E vs. PTX: 14.1 vs. 10.8 months; HR, 1.00 [95% CI, 0.58-1.73]) and overall survival (E vs. DTX: not reached [NR] vs. NR; E vs. PTX: 75.5 months vs. NR) were similar among the subgroups. Although the incidences of adverse events (AEs) were generally similar, peripheral sensory neuropathy was more frequent with PTX and less frequent with DTX, compared with E. Neutropenia tended to be more frequent with E. Median time to QoL deterioration was longer with E vs. DTX (7.8 vs. 4.7 months) and E vs. PTX (6.1 vs. 3.9 months).

CONCLUSIONS: This trial revealed comparable efficacy of E vs. either DTX or PTX, when combined with dual HER2 blockade as first-line treatment for HER2+ LABC/MBC. AEs were generally similar between the E and T subgroups. QoL was maintained for longer in the E subgroups vs. T subgroups.

ABSTRACT

IL-1 antagonists have emerged as an effective treatment for refractory or GC-dependent recurrent pericarditis (RP). This study aims to describe long-term efficacy and safety of anakinra in anakinra-treated RP patients and retrospectively explore the effect of early anakinra initiation and the risk of recurrence upon tapering. This is a retrospective study, based on medical records. The main outcome was any recurrence (“flare”) after anakinra initiation. Twenty patients (14 males, 6 females) were included with a median (IQR) disease duration of 48 (24) months, and 4 (2) recurrences prior to anakinra initiation. The median (IQR) age at pericarditis onset was 50 (31) years. Sixteen were on GC (mean (SD) prednisolone dose 17.7 (12.3) mg). Anakinra was initiated after a median (IQR) time of 11.5 (11.5) months from the first episode of acute pericarditis. Nineteen achieved remission on anakinra. Twelve achieved GC withdrawal while 4 remained on low-dose prednisolone (mean [SD] dose 3 mg [1]). Nine patients proceeded to tapering of anakinra after a median (IQR) of 8 (16) months on standard dosage and 7 patients remained on extended-interval administration at the end of the follow-up period. Flares occurred in 3/9 patients with a history of ≤ 3 pericarditis recurrences before anakinra initiation versus 4/11 with > 3 recurrences [exploratory univariable OR 1.14, (CI 0.13-11.13)] and in 2/5 patients treated early (< 6 months following diagnosis) versus 5/15 in the late-treated group (≥ 6 months) [exploratory univariable OR 0.76 (CI 0.06-11.94)]. Annualized recurrence rates were lower after anakinra initiation [median (IQR) recurrences 0 (0.26) versus 5.33 (4.68)]. In exploratory logistic regression analyses, neither early/late anakinra initiation, number of pre-anakinra recurrences, nor tapering was significantly associated with the outcome. The analyses’ findings should be interpreted with caution, given the limited sample size, the wide confidence intervals and the potential lack of statistical power to detect existing associations. In this cohort of RP patients, anakinra was associated with favorable clinical outcomes, allowing for GC sparing and achieving lower recurrence rates after initiation compared with the pre-treatment period. The sustained disease control observed supports its long-term use, either at full dose or with careful tapering. Exploratory comparisons for potential existing associations with flares were limited by small sample size. To determine the ideal treatment duration and tapering strategies, larger prospective controlled studies are required.

ABSTRACT

BACKGROUND: Epidemiological and clinical characteristics of primary pancreatic lymphoma (PPL) have been rarely reported in the literature. This study aimed to characterize the epidemiological features of PPL and develop robust nomograms for predicting patient survival outcomes.

METHODS: Patients diagnosed with PPL were extracted from the Surveillance, Epidemiology, and End Results (SEER) database for the period 1983-2015. Incidence rates of PPL were calculated for 1975-2018, and temporal trends were assessed using Joinpoint regression analysis. Cox proportional hazards regression models were applied to identify independent prognostic factors for overall survival (OS) and disease-specific survival (DSS). Nomograms were constructed based on independent clinicopathological factors to predict the probability of survival in PPL patients.

RESULTS: A total of 867 PPL patients were identified between 1983 and 2015, with a mean age at diagnosis of 65.7 years and a male-to-female ratio of 1.5:1. The overall age-adjusted incidence of PPL from 1975 to 2018 was 0.44 per 1,000,000 population, exhibiting a statistically significant increasing trend with an annual percentage change (APC) of 2.33 (95% confidence interval [CI]: 0.88-3.80, P < 0.05). Multivariate Cox regression analysis revealed that age, sex, marital status, pathological subtype, Ann Arbor stage, surgical intervention, and chemotherapy were independent prognostic factors for both OS and DSS (all P < 0.05). Nomograms were developed to predict 1-, 5-, and 10-year OS and DSS, and the predictive performance and calibration of these models were validated using the concordance index (C-index) and calibration curves, respectively.

CONCLUSION: PPL is an extremely rare malignancy, yet its incidence has increased steadily over the past four decades. The constructed nomograms can accurately predict 1-, 5-, and 10-year OS and DSS in PPL patients and effectively stratify patients into high-risk and low-risk groups, thus facilitating clinical decision-making.

ABSTRACT

Emotion detection from social media is crucial for understanding human emotions across languages. However, for low-resourced languages such as Amharic, the lack of annotated data makes this task challenging. Additionally, most current models use black-box methods that obscure whether predictions rely on linguistically meaningful cues. To address these gaps, this study proposes a multi-label emotion classification model for Amharic by fine-tuning AfroXLMR. To enhance transparency, we integrate explainable artificial intelligence (XAI) into the framework. We compiled and annotated a new dataset of 22,000 unique social media comments across eight emotion categories for training, validation, and testing. The data was split into 80% for training, 10% for validation, and 10% for testing. The proposed model achieved a recall of 87% and a Hamming loss of 0.08. To interpret its predictions, we applied Local Interpretable Model-agnostic Explanations (LIME). We also evaluated the model against several state-of-the-art baselines, including XLM-R base, mBART, BiLSTM, LSTM, CNN, and AfriBERTa. The results show that our approach outperformed each baseline, achieving F1-score improvements of 5% over XLM-R base, 3% over mBART, 5% over BiLSTM, 7% over LSTM, 9% over CNN, and 2% over AfriBERTa. Bootstrapped statistical significance testing confirms that these improvements are robust and not attributable to random variation. In conclusion, the fine-tuned AfroXLMR model demonstrates promising performance in Amharic multi-label emotion classification. Building on this success, next steps could involve exploring more advanced fine-tuning strategies and expanding our datasets to strengthen both performance and the model’s ability to generalize across diverse Amharic contexts.

ABSTRACT

BACKGROUND: Muscular dystrophy (MD) is a progressive neuromuscular disorder characterized by muscle degeneration, leading to fatigue, reduced endurance, and impaired functional capacity. Evidence regarding the role of therapeutic exercises in late-onset muscular dystrophies (LOMD) remains limited and inconclusive.

METHODS: A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted in accordance with PRISMA guidelines. Electronic databases including MEDLINE, Scopus, and Web of Science were searched from inception to September 2025. Eligible studies evaluated the effects of therapeutic exercises on fatigue, exercise tolerance, and aerobic capacity in individuals with LOMD. Data extraction and risk of bias assessment were performed independently by two reviewers. Meta-analysis was conducted using a random-effects model.

RESULTS: Eight RCTs involving 501 participants were included. Meta-analysis demonstrated small, statistically non-significant effects of therapeutic exercises on fatigue (SMD = -0.20; 95% CI: -0.72 to 0.33; p = 0.46), exercise tolerance (SMD = 0.16, 95% CI: -0.06 to 0.38; p = 0.15), and aerobic power (SMD = 0.12; 95% CI: -0.24 to 0.48; p = 0.51). Heterogeneity ranged from low to high across outcomes.

CONCLUSION: Therapeutic exercises appears to be a safe adjunct intervention and may provide small, although statistically non-significant, improvements in fatigue, exercise tolerance, and aerobic capacity in individuals with LOMD. While the findings suggest potential clinical benefits, the limited number of high-quality trials and heterogeneity warrant cautious interpretation. Further large-scale, well-designed RCTs are required to establish definitive evidence.
