Delirium is known to be underdiagnosed and underdocumented. Delirium detection in retrospective studies occurs mostly by clinician diagnosis or nursing documentation. This study aims to assess the effectiveness of natural language processing-confusion assessment method (NLP-CAM) algorithm when compared to conventional modalities of delirium detection. A multicenter retrospective study analyzed 4351 COVID-19 hospitalized patient records to identify delirium occurrence utilizing three different delirium detection modalities namely clinician diagnosis, nursing documentation, and the NLP-CAM algorithm. Delirium detection by any of the 3 methods is considered positive for delirium occurrence as a comparison. NLP-CAM captured 80% of overall delirium, followed by clinician diagnosis at 55%, and nursing flowsheet documentation at 43%. Increase in age, Charlson comorbidity score, and length of hospitalization had increased delirium detection odds regardless of the detection method. Artificial intelligence-based NLP-CAM algorithm, compared to conventional methods, improved delirium detection from electronic health records and holds promise in delirium diagnostics.

Abstract Aim To appraise the current evidence on the efficacy and safety of lamotrigine (LAM) in the treatment of pediatric mood disorders (PMD) (i.e., Major Depressive disorder [MDD], bipolar disorder [BD]). Methods Major databases were searched for randomized controlled trials (RCTs), open‐label trials, and observational studies reporting on pediatric (age < 18 years) patients treated with LAM for mood disorders. Results A total of 3061 abstracts were screened and seven articles were selected for inclusion. Seven studies (319 BD and 43 MDD patients), including one RCT ( n = 173), three prospective ( n = 105), and three retrospective ( n = 84) studies, met the study criteria with a study duration range from 8 to 60.9 weeks. The mean age of this pooled data is 14.6 ± 2.0 years. LAM daily dosage varied from 12.5 to 391.3 mg/day among the studies. In an important finding, the RCT reported favorable outcomes with LAM (HR = 0.46; p = 0.02) in 13‐ to 17‐year‐old age group as compared with 10‐ to 12‐year‐old age group (HR = 0.93; p = 0.88). In addition, time to occurrence of a bipolar event trended toward favoring LAM over placebo. All the studies identified LAM as an effective and safe drug in PMDs especially, BDs. Overall, LAM was well tolerated with no major significant side effects and no cases of Stevens–Johnson syndrome. Conclusions Most studies suggested that LAM was safe and effective in pediatric patients with mood disorders. However, the data regarding the therapeutic range for LAM are lacking. Based on the data, there is inconsistent evidence to make conclusive recommendations on therapeutic LAM dosage for mood improvement in the pediatric population. Further studies including larger sample sizes are required to address this relevant clinical question.

AbstractObjectivesThe assessment of physical function is fundamental in the management of patients with idiopathic inflammatory myopathies (IIMs). We aimed to investigate the physical function of patients with IIMs compared with those with non-IIM autoimmune rheumatic diseases (AIRDs) utilizing Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function (PF) data obtained in the COVAD study, an international self-reported e-survey assessing the safety of COVID-19 vaccines in AIRDs.MethodsDemographics, AIRD diagnosis, disease activity, and PROMIS PF short form-10a data were extracted from the COVAD database. PROMIS PF-10a scores were compared between disease categories and stratified by disease activity. Factors affecting PROMIS PF-10a scores other than disease activity were identified by multivariable regression analysis in patients with inactive disease.ResultsA total of 1057 IIM patients, 3635 non-IIM AIRD patients and 3981 healthy controls (HCs) responded to the COVAD e-survey from April to August 2021. Using a binomial regression model, the predicted mean of PROMIS PF-10a scores was significantly lower in IIM patients compared with non-IIM AIRD patients or HCs [36.3 (95% CI 35.5, 37.1) vs 41.3 (95% CI 40.2, 42.5) vs 46.2 (95% CI 45.8, 46.6), P &lt; 0.001], irrespective of disease activity. The independent factors for lower PROMIS PF-10a scores in patients with inactive disease were older age, female, longer disease duration, and a diagnosis of inclusion body myositis or polymyositis.ConclusionPhysical function is significantly impaired in IIMs compared with non-IIM AIRDs or HCs, even in patients with inactive disease. Our study highlights a critical need for better strategies to minimize functional disability in patients with IIMs.

Age at depressive onset (AAO) corresponds to unique symptomatology and clinical outcomes. Integration of genome-wide association study (GWAS) results with additional “omic” measures to evaluate AAO has not been reported and may reveal novel markers of susceptibility and/or resistance to major depressive disorder (MDD). To address this gap, we integrated genomics with metabolomics using data-driven network analysis to characterize and differentiate MDD based on AAO. This study first performed two GWAS for AAO as a continuous trait in (a) 486 adults from the Pharmacogenomic Research Network-Antidepressant Medication Pharmacogenomic Study (PGRN-AMPS), and (b) 295 adults from the Combining Medications to Enhance Depression Outcomes (CO-MED) study. Variants from top signals were integrated with 153 p180-assayed metabolites to establish multi-omics network characterizations of early (<age 18) and adult-onset depression. The most significant variant (p = 8.77 × 10−8) localized to an intron of SAMD3. In silico functional annotation of top signals (p < 1 × 10−5) demonstrated gene expression enrichment in the brain and during embryonic development. Network analysis identified differential associations between four variants (in/near INTU, FAT1, CNTN6, and TM9SF2) and plasma metabolites (phosphatidylcholines, carnitines, biogenic amines, and amino acids) in early- compared with adult-onset MDD. Multi-omics integration identified differential biosignatures of early- and adult-onset MDD. These biosignatures call for future studies to follow participants from childhood through adulthood and collect repeated -omics and neuroimaging measures to validate and deeply characterize the biomarkers of susceptibility and/or resistance to MDD development.

Abstract Purpose The aim of the study was to appraise the current evidence on the optimal serum level for lamotrigine (LAM) in the treatment of mood disorders (major depressive disorder, bipolar disorder). Methods Major databases were searched for randomized controlled trials, open-label trials, and observational studies reporting serum LAM levels in adult patients treated with LAM for mood disorders. Results A total of 814 abstracts were screened and 24 articles were selected for full-text review. Seven studies (226 bipolar disorder and 17 major depressive disorder patients) including 1 randomized controlled trial (n = 43), 3 prospective (n = 53), and 3 retrospective (n = 147) studies met the study criteria with a study duration range from 6 to 96 weeks. Lamotrigine daily dosage varied from 25 to 425 mg/d among the studies. Studies reported inconsistent findings between LAM concentration and efficacy. Three studies did not identify a relationship between LAM levels and a significant improvement in mood symptoms. Two studies (n = 99) reported higher response rates with LAM serum levels of greater than 3.25 μg/mL and 1 study (n = 25) reported a wide therapeutic window of 5 to 11 μg/mL. Overall, LAM was well tolerated with no major significant adverse effects. Conclusions Most studies showed a minimum LAM threshold level of 3 μg/mL in patients with mood disorders; however, the data are inconsistent regarding the therapeutic range for LAM. Based on the pooled data, there is inconsistent evidence to make conclusive recommendations on therapeutic LAM serum levels for mood improvement. Further studies including larger sample sizes are required to address this relevant clinical question.

Introduction: In the absence of high-quality evidence for Coronavirus disease-2019 (COVID-19), supportive care is advocated during this pandemic. We aim to develop a consensus statement from global experts for pharmacological management, based on the pathophysiology of COVID-19. Material and Methods: We used a modified Delphi methodology in three steps: 1) Formulation of the steering committee and questionnaire; 2) Delphi methodology and selection of experts; 3) Final meeting of the steering committee and analysis, discussion, preparation, and presentation of captured data. Results: 34 (73·9%) experts accepted the invitation for the study. We conducted two rounds of Delphi and consensus (>70% votes) was achieved on 11 out of 24 statements after the end of round two. Conclusion: This global consensus suggests that “Anti-viral therapy should be administered in the early infection phase of COVID-19 followed by low dose steroid therapy in pulmonary phase. Prophylactic dose anticoagulation should be used in hospitalized, mild to moderate COVID-19 patients. We make no suggestions for the use of immune modulation therapy”.

Abstract Purpose: The safety and preliminary efficacy of MEDI1873, an agonistic IgG1 fusion protein targeting glucocorticoid-induced TNF receptor–related protein (GITR), were evaluated in an open-label, first-in-human, phase I, dose escalation study in previously treated patients with advanced solid tumors. Patients and Methods: Two single-patient cohorts at 1.5 and 3 mg i.v. were followed by 3+3 dose escalation in six cohorts at 7.5, 25, 75, 250, 500, and 750 mg, all every 2 weeks, for up to 52 weeks. Primary endpoints were safety and tolerability, dose-limiting toxicities (DLT), and MTD. Secondary endpoints included antitumor activity, pharmacokinetics, immunogenicity, and pharmacodynamics. Results: Forty patients received MEDI1873. Three experienced DLTs: grade 3 worsening tumor pain (250 mg); grade 3 nausea, vomiting, and headache (500 mg); and grade 3 non-ST segment elevation myocardial infarction (750 mg). An MTD was not reached and treatment was well tolerated up to 500 mg. Most common treatment-related adverse events were headache (25%), infusion-related reaction (17.5%), and decreased appetite (17.5%). MEDI1873 exposure was dose proportional. Antidrug–antibody incidence was low. MEDI1873 increased peripheral CD4+ effector memory T-cell proliferation as well as cytokines associated with effector T-cell activation at dose levels ≥75 mg. The best response was stable disease (SD) in 17 patients (42.5%), including 1 unconfirmed partial response. Eight patients (20.0%) had SD ≥24 weeks. Conclusions: MEDI1873 showed acceptable safety up to 500 mg i.v. every 2 weeks with pharmacodynamics activity, and prolonged SD in some patients. However, further development is not planned because of lack of demonstrated tumor response.

Abstract Hydrogen sulfide (H2S), the third gasotransmitter, has recently attracted a lot of attention for its cytoprotective action and role in angiogenesis. Dysregulation of the major enzymes which produces H2S namely, cystathionine beta synthase (CBS), cystathionine gamma lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3-MST) have also been implicated in a large number of pathological conditions that range from neurological disorders to cardiovascular diseases. Surprisingly, studies on the role of these enzymes in cancer is scarce, especially, that of CBS. Relapse with a drug resistant and aggressive phenotype is a common occurrence in ovarian cancer with an overall 5-year survival of approximately 30%. Here we report that, CBS, a key enzyme required for sulphur amino acid metabolism, plays a critical role in promoting ovarian cancer growth, metastasis and drug resistance. Overexpression of CBS was observed in a majority of ovarian cancer cell lines utilized in our study compared to normal ovarian surface epithelial cells. Silencing CBS in A2780 cells using siRNA or a CBS-specific inhibitor, aminooxyacetic acid reduced proliferation of ovarian cancer cells by dramatically reducing total glutathione levels, H2S levels and thereby enhancing oxidative stress. Downregulation of CBS reduced activation of NF-kB and upregulated p53 protein levels thereby inactivating the antioxidant network of the cells. A deeper insight into the intracellular localization of CBS by confocal fluorescence microscopy demonstrated a mitochondria specific distribution and silencing CBS caused mitochondrial superoxide accumulation that resulted in decreased mitochondrial respiration, reduced ATP production and increased ADP-to-ATP ratio. Furthermore, silencing CBS, augmented the activity of cisplatin in vitro in A2780 cells and in vivo in an orthotopic model of advanced ovarian cancer. Nanoliposomal delivery of CBS siRNA significantly reduced the number of tumor nodules in a chemoresistant orthotopic mouse model of ovarian cancer. To our knowledge, this is the first study demonstrating the importance of CBS in ovarian cancer progression and drug resistance and therefore is a viable target for future anti-cancer therapies.
