    Abstract In mass spectrometry (MS)-based metabolomics, there is a great need to combine different analytical separation techniques to cover metabolites of different polarities and apply appropriate multi-platform data processing. Here, we introduce AriumMS (augmented region of interest for untargeted metabolomics mass spectrometry) as a reliable toolbox for multi-platform metabolomics. AriumMS offers augmented data analysis of several separation techniques utilizing a region-of-interest algorithm. To demonstrate the capabilities of AriumMS, five datasets were combined. This includes three newly developed capillary electrophoresis (CE)-Orbitrap MS methods using the recently introduced nanoCEasy CE-MS interface and two hydrophilic interaction liquid chromatography (HILIC)-Orbitrap MS methods. AriumMS provides a novel mid-level data fusion approach for multi-platform data analysis to simplify and speed up multi-platform data processing and evaluation. The key feature of AriumMS lies in the optimized data processing strategy, including parallel processing of datasets and flexible parameterization for processing of individual separation methods with different peak characteristics. As a case study, Saccharomyces cerevisiae (yeast) was treated with a growth inhibitor, and AriumMS successfully differentiated the metabolome based on the augmented multi-platform CE-MS and HILIC-MS investigation. As a result, AriumMS is proposed as a powerful tool to improve the accuracy and selectivity of metabolome analysis through the integration of several HILIC-MS/CE-MS techniques.

    Abstract Management of obesity requires a multidisciplinary approach including physical activity interventions, which have significant impacts on overall health outcomes. Greater levels of lean muscle mass are significantly associated with improved health and reduced risk of comorbidities and should be preserved where possible when undertaking rapid weight loss. This article reports on the physical and functional outcomes achieved during a 12-week intensive multidisciplinary intervention targeting obesity and evaluates correlations between body composition and functional outcomes. We additionally aimed to investigate the test-retest reliability and levels of agreement in body composition measurements using bioimpedance spectroscopy between seated and standing positions. Of the 35 participants included in analysis, significant differences were observed between baseline and post-intervention measures. These included weight loss of 12.6 kg, waist circumference reduction of 10.5 cm, fat mass reduction by 2.9%, muscle mass increase by 1.6%, 54.5 m improvement in the 6-minute walk test and 3.8 rep improvement in the 30-second sit-to-stand test. No significant correlations were observed between physical and functional outcome measures. Excellent test re-test reliability was observed in bioimpedance spectroscopy seated measurements (ICC >.9). Significant differences were observed between seated and standing bioimpedance spectroscopy measurements, however they are regarded as small differences in a clinical setting.

    Abstract N-linked glycosylation is one of the most important post-translational modifications of monoclonal antibodies (mAbs) and is considered to be a critical quality attribute (CQA), as the glycan composition often has immunomodulatory effects. Since terminal galactose residues of mAbs can affect antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytolysis (CDC) activation, serum half-life, and antiviral activity it has to be monitored, controlled and modulated to ensure therapeutic effects. The ability of small noncoding microRNAs (miRNAs) to modulate glycosylation in Chinese hamster ovary (CHO) production cells was recently reported establishing miRNAs as engineering tools for modulation of protein glycosylation. In this study, we report the characterization and validation of miRNAs as engineering tools for increased (mmu-miR-452-5p, mmu-miR-193b-3p) or decreased (mmu-miR-7646-5p, mmu-miR-7243-3p, mmu-miR-1668, mmu-let-7c-1-3p, mmu-miR-7665-3p, mmu-miR-6403) degree of galactosylation. Furthermore, the biological mode of action regulating gene expression of the galactosylation pathway was characterized as well as their influence on bioprocess-related parameters. Most important, stable plasmid-based overexpression of these miRNAs represents a versatile tool for engineering N-linked galactosylation to achieve favorable phenotypes in cell lines for biopharmaceutical production.

    Abstract Purpose: The primary aim of this study was to compare the attendance rates at a group lymphoedema education and same-day individual surveillance appointment between telehealth (TH) and in-person (IP) care for participants following breast cancer (BC) surgery. Secondary aims included evaluating participant satisfaction and costs between the two service models, while also determining the extent of technical issues and clinician satisfaction towards TH.
    Methods: Participants following axillary lymph node dissection surgery attended a group lymphoedema education and same-day 1:1 monitoring session via their preferred mode (TH or IP). Attendance rates, satisfaction and costs were recorded for both cohorts, and technical disruption and clinician satisfaction for the TH cohort.
    Results: Fifty-five individuals participated. All 28 participants who nominated the IP intervention attended, while 22/27 who nominated the TH intervention attended an appointment. Overall reported participant experience was positive with no significant differences between cohorts. All TH appointments were successfully completed. Clinicians reported high satisfaction for delivery of education (median = 4[IQR 4-5]) and individual assessment (median = 4[IQR 3-4]) via TH. Median attendance costs per participant were Australian $39.68 (Q1-Q3 $28.52-$68.64) for TH and Australian $154.26 (Q1-Q3 $81.89-$251.48) for the IP cohort.
    Conclusion: Telehealth-delivered lymphoedema education and assessment for individuals following BC surgery was associated with favourable satisfaction, cost savings and minimal technical issues despite lower attendance than IP care. This study contributes to the growing evidence for TH and its potential applicability to other populations where risk for cancer-related lymphoedema exists.

    Abstract The aim of the two presented studies was to evaluate the factor structure and psychometric properties of the newly developed German Metacognitions Questionnaire for children (MKF-K, Study 1) and the translated German Cognitive Avoidance Questionnaire (CAQ-D, Study 2) for adults. Further, the relevance of both constructs for pathological worrying and other psychopathologically relevant conditions was evaluated. The factor structure of both instruments was examined using explanatory and confirmatory factor analyses. Construct validity was assessed by correlation coefficients with related constructs and hierarchical regression analyses predicting worry and anxiety in a children's sample (Study 1) consisting of 972 participants aged 7-14 years and positive and negative metacognitions, as well as worry and depressive symptoms in an adult sample (Study 2) consisting of 397 participants (mean age 24 years). In addition to psychometric analyses, age effects of metacognitions and the transdiagnostic value of cognitive avoidance were considered. Participants in Study 1 completed the German versions of the Penn State Worry Questionnaire for Children (PSKJ) and Spence Children Anxiety Scale (SCAS-D) in addition to the MKF-K. Participants in Study 2 completed the German versions of the Penn State Worry Questionnaire (PSWQ), Metacognition Questionnaire (MKF-30), Beck Depression Inventory (BDI-V), Response Style Questionnaire (RSQ-D), and the CAQ-D. The fit indices of the factor structure of both measures indicate moderate to good model fits. Results confirm good psychometric properties in general. Both constructs contributed significantly to the prediction of worrying and anxiety independent of the developmental status (Study 1), and negative metacognitions, worrying, and depressive symptoms (Study 2), even after controlling for demographic variables and related constructs. It is concluded that the German MKF-K serves as a reliable and valid instrument for the assessment of different metacognitive beliefs in childhood and the CAQ-D for cognitive avoidance strategies in adulthood. Metacognitions and cognitive avoidance are relevant constructs to at least two highly relevant psychopathological conditions (anxiety and depression) across the lifespan. The studies provide further support for the validity of both constructs for persistent recurring and intrusive thoughts. Furthermore, metacognitions and cognitive avoidance are important transdiagnostic risk factors.

    Abstract The analysis of monoclonal antibodies glycosylation is a crucial quality control attribute of biopharmaceutical drugs. High throughput screening approaches for antibody glycoform analysis are required in various stages of process optimization. Here, we present high throughput screening suitable mass spectrometry‐based workflows for the analysis of intact antibody glycosylation out of cell supernatants. Capillary electrophoresis and liquid chromatography were coupled with quadrupole time‐of‐flight mass spectrometry or Orbitrap mass spectrometry. Both separation methods offer fast separation (10–15 min) and the capability to prevent the separated cell supernatant matrix to enter the mass spectrometry by post‐separation valving. Both mass spectrometry instruments provide comparable results and both are sufficient to determine the glycosylation pattern of the five major glycoforms of the measured antibodies. However, the Orbitrap yields higher sensitivity of 25 μg/mL (CE‐nanoCEasy‐Orbitrap mass spectrometry) and 5 μg/mL (liquid chromatography‐Orbitrap mass spectrometry). Data processing was optimized for a faster processing and easier detection of low abundant glycoforms based on averaged charge‐deconvoluted mass spectra. This approach combines a non‐target glycoform analysis while yielding the same glycosylation pattern as the traditional approach based on extracted ion traces. The presented methods enable the high throughput screening of the glycosylation pattern of antibodies down to low μg/mL‐range out of cell supernatant without any sample preparation.
