Canada is in the midst of an ongoing, escalating opioid crisis, with significant impacts on adolescents and young adults. Accordingly, mental health impairment was examined as a risk factor for non-medical prescription opioid use (NMPOU) among high school students. In addition, the moderating effects of the school environment, in terms of the availability of mental health services and substance use policies, were characterized. Self-reported, cross-sectional data were obtained from the COMPASS study, including 61,239 students (grades 9-12) in 121 secondary schools across Canada. Current and lifetime NMPOU were ascertained. Categorical indicators of mental health impairment and school environment were derived. The main analytical strategy encompassed hierarchal multilevel logistic regression, including the addition of interaction terms to characterize the moderation effects. Current and lifetime NMPOU were reported by 5.8% and 7.2% of the students, respectively. After adjusting for confounders, students in the highest quintile of mental health impairment had odds ratios (OR) of 2.60 (95% confidence interval [CI] 2.29-2.95) and 2.96 (95% CI 2.64-3.33) for current and lifetime NMPOU, respectively when compared to students in the lowest quintile of mental health impairment. mTOR inhibitor therapy A significant interaction between mental health impairment and school environment indicated relatively lower risks of NMPOU in students from schools that provide more mental health services and have stricter substance use policies. Mental health impairment increased the risk of NMPOU, but the associations were moderated by the school environment. These findings underscore the importance of mental health services and substance use regulations in schools.The antenna is a key sensory organ in insects. Factors which pattern its epithelium and the spacing of sensillae will play an important role in shaping its contribution to adaptive behavior. The antenna of the grasshopper S. gregaria has three major articulations scape, pedicel, and flagellum. During postembryonic development, the flagellum lengthens as segments (so-called meristal annuli) are added at each molt. However, the five most apical annuli do not subdivide; thus, their epithelial domains must already be defined during embryogenesis. We investigated epithelial compartmentalization and its relationship to the developing primordial nervous system of the antenna by simultaneous immunolabeling against the epithelial cell surface molecule Lachesin, against neuron-specific horseradish peroxidase, and against the mitosis marker phospho-histone 3. We found that Lachesin is initially expressed in a highly ordered pattern of "rings" and a "sock" in the apical antennal epithelium of the early embryo. These expression domains appear in a stereotypic order and prefigure later articulations. Proliferative cells segregate into these developing domains and pioneer- and sensory-cell precursors were molecularly identified. Our study allows pioneer neurons, guidepost cells, and the earliest sensory cell clusters of the primordial nervous system to be allocated to their respective epithelial domain. As the apical-most five domains remain stable through subsequent development, lengthening of the flagellum must originate from more basal regions and is likely to be under the control of factors homologous to those which regulate boundary and joint formation in the antenna of Drosophila.The original article has been corrected.AIMS To investigate whether intravitreal conbercept injection affects contralateral untreated eyes in bilateral diabetic macular edema (DME) patients. METHODS In this retrospective study, 15 patients (30 eyes) with type 2 diabetes were followed after bilateral DME diagnosis in the Department of Ophthalmology, Peking Union Medical College Hospital from 2015 to 2018. Patients underwent examinations including best corrected visual acuity (BCVA), slit-lamp microscopy, indirect ophthalmoscope, color fundus photography, fundus fluorescein angiography, optical coherence tomography, and glycated hemoglobin (HbA1c). Each patient received conbercept (0.5 mg) intravitreally in the severe eye. Nonparametric Wilcoxon signed-rank tests and Pearson's correlation coefficient were used to assess changes in BCVA and central retinal thickness (CRT) and relations between BCVA changes in treated and untreated eyes, respectively. RESULTS The mean follow-up time was 10.60 ± 2.29 months, and the mean injection number of 15 treated eyes was 9.13 ± 0.68. HbA1c remained below 10% during treatment with no significant changes between the initial and final visits (7.81 ± 1.17 vs 7.62 ± 1.19%) (P = 0.576). In untreated eyes, CRT significantly decreased from the initial to final visits (368.93 ± 125.45 vs 306.27 ± 89.70 μm) (P = 0.028). In untreated eyes, BCVA showed no significant difference between the initial and final visits (0.38 ± 0.30 vs 0.40 ± 0.30 logMAR) (P = 0.937), but BCVA changes in treated and untreated eyes were positively correlated (r = 0.527, P = 0.044). CONCLUSIONS Intravitreal conbercept injection results in decreased CRT and increased BCVA in untreated eyes, which is consistent with the changes in treated eyes for patients with bilateral DME.In decapods, dopamine, octopamine, serotonin, and histamine function as locally released/hormonally delivered modulators of physiology/behavior. Although the functional roles played by amines in decapods have been examined extensively, little is known about the identity/diversity of their amine receptors. Recently, a Homarus americanus mixed nervous system transcriptome was used to identify putative neuronal amine receptors in this species. While many receptors were identified, some were fragmentary, and no evidence of splice/other variants was found. Here, the previously predicted proteins were used to search brain- and eyestalk ganglia-specific transcriptomes to assess/compare amine receptor complements in these portions of the lobster nervous system. All previously identified receptors were reidentified from the brain and/or eyestalk ganglia transcriptomes, i.e., dopamine alpha-1, beta-1, and alpha-2 (Homam-DAα2R) receptors, octopamine alpha (Homam-OctαR), beta-1, beta-2, beta-3, beta-4, and octopamine-tyramine (Homam-OTR-I) receptors, serotonin type-1A, type-1B (Homam-5HTR1B), type-2B, and type-7 receptors; and histamine type-1 (Homam-HA1R), type-2, type-3, and type-4 receptors. For many previously partial proteins, full-length receptors were deduced from brain and/or eyestalk ganglia transcripts, i.e., Homam-DAα2R, Homam-OctαR, Homam-OTR-I, and Homam-5HTR1B. In addition, novel dopamine/ecdysteroid, octopamine alpha-2, and OTR receptors were discovered, the latter, Homam-OTR-II, being a putative paralog of Homam-OTR-I. Finally, evidence for splice/other variants was found for many receptors, including evidence for some being assembly-specific, e.g., a brain-specific Homam-OTR-I variant and an eyestalk ganglia-specific Homam-HA1R variant. To increase confidence in the transcriptome-derived sequences, a subset of receptors was cloned using RT-PCR. These data complement/augment those reported previously, providing a more complete picture of amine receptor complement/diversity in the lobster nervous system.PURPOSE In hepatobiliary surgery, preoperative three-dimensional reconstruction based on CT or MRI can be provided externally or by local, semi-automatic software. We analyzed the time expense and quality of external versus local three-dimensional reconstructions. METHODS Three first-year residents reconstructed data from 20 patients with liver pathologies using a local, semi-automatic, server-based program. Initially, five randomly selected patient datasets were segmented, with the visualization of an established external company available for comparison at all times (learning phase). The other fifteen cases were compared with the external datasets after completing local reconstruction (control phase). Total time expense/case and for specific manual and semi-automated reconstruction steps were recorded. Segmentation quality was analyzed by testing the equivalence for liver and tumor volumes, portal vein sectors, and hepatic vein territories. RESULTS The median total reconstruction time was reduced from 2.5 h (learning phase) to 1.5 h (control phase) (- 42%; p  less then  0.001). Comparing the total and detailed liver volumes (sectors and territories) as well as the tumor volumes in the control phase equivalence was proven. In addition, a highly significant correlation between the external and local analysis was obtained over all analyzed segments with a very high ICC (median [IQR] 0.98 [0.97; 0.99]; p  less then  0.01). CONCLUSION Local, semi-automatic reconstruction performed by inexperienced residents was feasible with an expert level time expense and the quality of the three-dimensional images was comparable with those from an external provider.Previous studies have demonstrated the efficacy of metacognitive training (MCT) in schizophrenia. However, the underlying mechanisms related to therapeutic effect of MCT remain unknown. The present study explored the treatment effects of MCT on brain regional neural activity using regional homogeneity (ReHo) and whether these regions' activities could predict individual treatment response in schizophrenia. Forty-one patients with schizophrenia and 20 healthy controls were scanned using resting-state functional magnetic resonance imaging. Patients were randomly divided into drug therapy (DT) and drug plus psychotherapy (DPP) groups. The DT group received only olanzapine treatment, whereas the DPP group received olanzapine and MCT for 8 weeks. The results revealed that ReHo in the right precuneus, left superior medial prefrontal cortex (MPFC), right parahippocampal gyrus and left rectus was significantly increased in the DPP group after 8 weeks of treatment. Patients in the DT group showed significantly increased ReHo in the left ventral MPFC/anterior cingulate cortex (ACC), left superior MPFC/middle frontal gyrus (MFG), left precuneus, right rectus and left MFG, and significantly decreased ReHo in the bilateral cerebellum VIII and left inferior occipital gyrus (IOG) after treatment. Support vector regression analyses showed that high ReHo levels at baseline in the right precuneus and left superior MPFC could predict symptomatic improvement of Positive and Negative Syndrome Scale (PANSS) after 8 weeks of DPP treatment. Moreover, high ReHo levels at baseline and alterations of ReHo in the left ventral MPFC/ACC could predict symptomatic improvement of PANSS after 8 weeks of DT treatment. This study suggests that MCT is associated with the modulation of ReHo in schizophrenia. ReHo in the right precuneus and left superior MPFC may predict individual therapeutic response for MCT in patients with schizophrenia.PURPOSE Research has elucidated the impact of post-exercise carbohydrate nutrition and environmental conditions on muscle glycogen re-synthesis. However, research has minimally considered the implications of glycogen recovery in females and has mostly focused on commercial sport nutrition products. The purpose of this study was to determine the effects of varied mixed macronutrient feedings on glycogen recovery and subsequent exercise performance in both sexes. METHODS Males (n = 8) and females (n = 8) participated in a crossover study. Subjects completed a 90-min cycling glycogen depletion trial, then rested for 4 h. Two carbohydrate feedings (1.6 g kg-1) of either sport supplements or potato-based products were delivered at 0 and 2 h post-exercise. Muscle biopsies (glycogen) and blood samples (glucose, insulin) were collected during the recovery. Afterwards, subjects completed a 20 km cycling time trial. RESULTS There was no difference between sexes or trials for glycogen recovery rates (male 7.9 ± 2.7, female 8.
