Mentalization in young patients undergoing opioid agonist treatment: Implications for clinical management

Background: Mentalization is the ability to use internal mental states to manage and understand one's own and others' behavior. Inefficient mentalization has been associated to poor neuropsychological outcomes, including substance use disorder (SUD) and addiction. However, studies primarily investigating mentalization in SUD are lacking. Methods: Using the Reflective Functioning Questionnaire (RFQ), the Measurements in the Addictions for Triage and Evaluation, version 2.1 (MATE-IT-2.1), and the Mini International Neuropsychiatric Interview, 7th edition (MINI-7), an outpatient assessment investigated inefficient mentalization (i.e., 'hypo-mentalization' or 'uncertainty': concrete thinking with poor attribution of mental states; 'hyper-mentalization' or 'certainty': rigid and biased attribution of mental states) and socio-demographic and clinical characteristics, including SUD-related symptoms and any other psychiatric comorbidity, among opioid addiction (OA) patients in Opioid Agonist Treatment (OAT). Results: Thirty-seven consecutive OA patients in OAT (female, 45.9 %; age, M ± SD, 24.3 ± 3.55) were recruited. Patients' mentalization differed from normative data, in terms of higher uncertainty and lower certainty scores. Also, higher uncertainty score was found among younger patients and in those with the most severe SUD in terms of craving and need for care. Finally, lower certainty score was found in those with a more severe substance abuse, previous contacts with pediatric mental-health services, and receiving a therapeutic community support. Conclusions: OA patients with inefficient mentalization present with a higher burden in terms of SUD severity, comorbidities, psychosocial disabilities, and service use, with important public health implications. Interventions targeting mentalization may have positive repercussions in preventing SUD, mitigating its severity, and containing its healthcare and social costs

Effect of Finishing Systems on Surface Roughness and Gloss of Full-Body Bulk-Fill Resin Composites

Background: In this study, we assess the effect produced on roughness and gloss of full-body bulk-fill materials by different finishing and polishing systems. Methods: Four full-body bulk-fill materials were tested: SonicFill2 (SF), Filtek Bulk Fill Posterior Restorative (FB), Tetric EvoCeram bulk-fill (EC), and Fill-Up! (FU). Sixty discs per material (2 mm in thickness and 7 mm in diameter) were obtained and randomly assigned (n = 15) to four finishing and polishing methods: Sof-Lex Spiral Wheels (SW), HiLusterPLUS (HL), Astropol (AP), and Opti1Step (OS). Surface roughness and gloss were then measured. Results: For roughness, material and surface treatment were significant factors (p < 0.001) with SF = FB = EC < FU and AP < SW < HL = OS. Material and surface treatment had a significant effect also on gloss (p < 0.001), with SF > FB = EC > FU and SW > AP > HL > OS. Conclusions: The tested combinations of bulk-fill and polishing systems provided clinically acceptable results with regard to roughness, while the outcome was poor for gloss. Multistep finishing/polishing systems were able to produce smoother surfaces on full-body bulk-fill materials compared to simplified ones

European Multicenter Study of ET-COVID-19

International audienceBackground and Purpose: Acute ischemic stroke and large vessel occlusion can be concurrent with the coronavirus disease 2019 (COVID-19) infection. Outcomes after mechanical thrombectomy (MT) for large vessel occlusion in patients with COVID-19 are substantially unknown. Our aim was to study early outcomes after MT in patients with COVID-19. Methods: Multicenter, European, cohort study involving 34 stroke centers in France, Italy, Spain, and Belgium. Data were collected between March 1, 2020 and May 5, 2020. Consecutive laboratory-confirmed COVID-19 cases with large vessel occlusion, who were treated with MT, were included. Primary investigated outcome: 30-day mortality. Secondary outcomes: early neurological improvement (National Institutes of Health Stroke Scale improvement ≥8 points or 24 hours National Institutes of Health Stroke Scale 0–1), successful reperfusion (modified Thrombolysis in Cerebral Infarction grade ≥2b), and symptomatic intracranial hemorrhage. Results: We evaluated 93 patients with COVID-19 with large vessel occlusion who underwent MT (median age, 71 years [interquartile range, 59–79]; 63 men [67.7%]). Median pretreatment National Institutes of Health Stroke Scale and Alberta Stroke Program Early CT Score were 17 (interquartile range, 11–21) and 8 (interquartile range, 7–9), respectively. Anterior circulation acute ischemic stroke represented 93.5% of cases. The rate modified Thrombolysis in Cerebral Infarction 2b to 3 was 79.6% (74 patients [95% CI, 71.3–87.8]). Thirty-day mortality was 29% (27 patients [95% CI, 20–39.4]). Early neurological improvement was 19.5% (17 patients [95% CI, 11.8–29.5]), and symptomatic intracranial hemorrhage was 5.4% (5 patients [95% CI, 1.7–12.1]). Patients who died at 30 days exhibited significantly lower lymphocyte count, higher levels of aspartate, and LDH (lactate dehydrogenase). After adjustment for age, initial National Institutes of Health Stroke Scale, Alberta Stroke Program Early CT Score, and successful reperfusion, these biological markers remained associated with increased odds of 30-day mortality (adjusted odds ratio of 2.70 [95% CI, 1.21–5.98] per SD-log decrease in lymphocyte count, 2.66 [95% CI, 1.22–5.77] per SD-log increase in aspartate, and 4.30 [95% CI, 1.43–12.91] per SD-log increase in LDH). Conclusions: The 29% rate of 30-day mortality after MT among patients with COVID-19 is not negligible. Abnormalities of lymphocyte count, LDH and aspartate may depict a patient’s profiles with poorer outcomes after MT. Registration: URL: https://www.clinicaltrials.gov . Unique identifier: NCT04406090
