Microtubule-severing enzymes - katanin, spastin, fidgetin - are related AAA-ATPases that cut microtubules into shorter filaments. These proteins, also called severases, are involved in a wide range of cellular processes including cell division, neuronal development, and tissue morphogenesis. Paradoxically, severases can amplify the microtubule cytoskeleton and not just destroy it. Recent work on spastin and katanin has partially resolved this paradox by showing that these enzymes are strong promoters of microtubule growth. Here, we review recent structural and biophysical advances in understanding the molecular mechanisms of severing and growth promotion that provide insight into how severing enzymes shape microtubule networks.
To assess whether optimised oral care including subglottic suction could reduce microaspiration in comparison with a routine oral care.

An open prospective study comparing optimized»versus a routine oral care procedure in two randomised crossover consecutive periods of oneday each. Optimised oral care consisted of suction via the subglottic suction port before and after a 10 seconds chlorhexidine oral care, compared with no use of the port during routine care.

Single-centre inclusion of critically ill patients ventilated for ≥48hours with a subglottic suction endotracheal tube, no curare, Ramsay score not <3, and semi-quantitative assessments of tracheal secretions ≥ ++.

Amylase being a relevant surrogate for oropharyngeal content, microaspirations were defined by tracheal/oral amylase ratio.

21 patients (11 and 10 with routine and optimised care in the first day respectively) with no baseline difference in risk of microaspiration. Neither difference in tracheal amylase amount or in tracheal/oral amylase ratio (1.5% (0.7%-16%) and 2.3% (0.6%-6%), p=0.37) was observed indicating that microaspirations were not significantly decreased after optimized versus routine oral care.

Suctioning by the subglottic port of endotracheal tubes may not decrease the risk of microaspiration during oral care of ventilated patients.

To assess the possibility of differentiating pulmonary carcinoids from hamartomas and typical from atypical carcinoids by means of
F-FDG PET/CT.

We retrospectively reviewed 139 patients with pathologically proven pulmonary carcinoids and hamartomas who underwent
F-FDG PET/CT before surgical resection. Receiver operating characteristics curves were calculated to determine the potential of SUVmax to discriminate between pulmonary carcinoids and hamartomas, typical and atypical carcinoids. #link# The correlation between SUVmax and tumor size was analyzed by Spearman correlation analysis.

SUVmax was significantly higher in pulmonary carcinoids than in hamartomas (p<0.001), and also higher in atypical carcinoids than in typical carcinoids (p = 0.034). With a SUVmax of 2.0 as a cutoff, the sensitivity, specificity, positive predictive value, and negative predictive value for
F-FDG PET/CT to differentiate pulmonary carcinoids from hamartomas were 85.3%, 82.9%, 61.7%, and 94.6%, respectively. The cutoff value of SUVmax for differentiating atypical carcinoids from typical carcinoids was 4.1. The area under the receiver operating characteristics curve of SUVmax was 0.900 for carcinoids and hamartomas, and 0.722 for typical and atypical carcinoids. SUVmax was correlated with maximum tumor size in pulmonary carcinoids (r = 0.658, p <0.001) and in pulmonary hamartomas (r = 0.672, p <0.001).

F-FDG PET/CT might be a useful tool in the differential diagnosis of carcinoids and hamartomas, and can also distinguish atypical from typical carcinoids. This may facilitate improved selection of patients for surgical resection and radiological follow-up.

To provide updated information on the effect of clinical history on diagnostic image interpretation and to provide study methodology and design recommendations for future studies assessing the effect of clinical history on diagnostic image performance.

A literature search of Medline, Embase, Scopus, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases was conducted from database inception to July 21, 2020. Studies comparing diagnostic imaging performance with and without clinical history, using observers reading images under both conditions that used an independent reference standard were included.

Twenty-two studies met the inclusion criteria, with 15 showing clinical history improved diagnostic performance. One study reported a decrease in diagnostic performance with clinical history and the remaining six studies found no significant change in performance. Two studies used the free response paradigm with both reporting clinical history increased location sensitivity, decreased specificity and had no overall change in diagnostic performance. selleck products of included cases was largely unreported and a balanced reading design was not used in 19 studies.

Most published studies found that clinical history improved diagnostic performance. More recent studies accounting for abnormality location and multiple abnormalities showed an increase in false positives and no significant change in overall diagnostic performance with clinical history.

The aim of this study was to assess the potential benefit of a high-fat meal for preparation of patients before lymphangiography of the thoracic and abdominal lymphatic vessels by a heavily T2-weighted 3D magnetic resonance sequence at 3T.

A heavily T2-weighted 3D Fast-Spin-Echo sequence was applied twice for lymphangiography in 15 healthy volunteers. One examination was performed following overnight fasting and the second examination was conducted 3 hours after a drinking of 200 ml of cream and a solid meal. The effect of a high-fat meal on the visualization of different segments of the thoracic and abdominal lymphatic vessels was analyzed by scoring of the image quality.

Evaluation of the summarized score of all four segments of the thoracic duct showed significantly improved general visualization of the lymphatic system in the postprandial examination when compared to the results obtained after overnight fasting (mean ± SD 4.5 ± 1.7 vs. 5.9 ± 1.8, p = 0.007*). Regarding different segments of the lymphatic system significant differences between pre and post cream lymphangiographies were found in the cervical segment (p = 0.012*), the inferior thoracic segment (p = 0.003*) and the abdominal segment (p = 0.035*). In contrast, the visualization of the superior thoracic segment was not significantly improved by high fat meal preparation of the subjects (p = 0.388).

A high-fat meal 3 hours prior to T2-weighted MR-lymphangiography improves the visualization of the main lymphatic thoracic and abdominal vessels, particularly the abdominal and cervical part as well as the inferior segment of the thoracic duct.

B cells infiltrating most established tumors have been associated with a dual role Some studies have associated antibodies produced by tumor-associated B cells with the promotion of regulatory activities on myeloid cells, and also with direct immunosuppression through the production of IL-10, IL-35 or TGF-β. link3 In contrast, recent studies in multiple human malignancies identify B cell responses with delayed malignant progression and coordinated T cell protective responses. This includes the elusive role of Tertiary Lymphoid Structures identified in many human tumors, where the function of B cells remains unknown. Here, we discuss emerging data on the dual role of B cell responses in the pathophysiology of human cancer, providing a perspective on future directions and possible novel interventions to restore the coordinated action of both branches of the adaptive immune response, with the goal of maximizing immunotherapeutic effectiveness.
To conduct a systematic review of published evidence on clozapine prescribing disparities across racial and ethnic categories, estimate the size of these disparities, and assess possible causes to inform future monitoring and intervention.

Electronic databases (MEDLINE, Embase, PsycINFO, Web of Science) were searched for directly relevant studies. Three independent reviewers selected studies (1) of US samples; (2) directly addressed ethnic and/or racial disparities in prescribing of antipsychotic medications; (3) identified specific ethnic and/or racial groups (e.g. White, Blacks, Hispanics, non-Hispanic etc.); (4) reported clozapine prescription rates and (5) reported relevant covariates (i.e. gender, age, co-morbidities etc.).

16 studies met our eligibility criteria. All studies reported clozapine underutilization in ethnic and racial minority patients when compared to their white counterparts. These findings remained consistent despite different time periods, designs, data set types, and after controlling for relevant covariates such as length of hospital stay, institutional setting, and disease severity.

The reasons for underutilization of clozapine in minority patients remain unclear. Various contributors can be categorized as clinician-related factors (e.g. prescriber lack of experience), patient-related factors (e.g. distrust or suspicion of clinician), and institution-related factors (e.g. state operated facilities). Direct examination of these factors can help inform efforts to reduce clozapine prescription disparities.

This study aims to find the prevalence of medication non-compliance among schizophrenia inpatients and to compare the relative risks of medication non-compliance with cannabis use disorders (CUDs) versus without CUDs. In addition, this study also examines the odds of medication non-compliance in schizophrenia inpatients with CUDs.

This is a retrospective cross-sectional analysis of the nationwide inpatient sample. This sample includes 1,030,949 inpatients (age 18 to 65years) from 2010 to 2014 with primary ICD-9 diagnoses of schizophrenia and other psychotic disorders, that were further sub grouped based on medication non-compliance. CUDs were recognized using the ICD-9 codes.

The prevalence of medication non-compliance was 26% among schizophrenia inpatients. Multivariable analysis revealed that CUD comorbidity was a significant risk factor for medication non-compliance among schizophrenia patients when unadjusted (OR 1.49, 95%CI 1.469-1.503), and association remained significant even after adjusting for covariates (adjusted OR 1.
