Daratumumab infusion reaction rates pre- and post-addition of montelukast to pre-medications

Daratumumab, a CD38-directed monoclonal antibody indicated for multiple myeloma treatment in adult patients, is associated with a high incidence of infusion-related reactions (IRRs). Due to CD38 receptor presence in the lungs, many reactions present similarly to asthma or allergic rhinitis. Montelukast, a leukotriene receptor antagonist, has been hypothesized to reduce daratumumab IRRs due to its efficacy in treating allergic rhinitis and asthma and the presence of leukotriene receptors in the lungs. Recently published data reported daratumumab can be safely administered via rapid rate protocol that reduces infusion time from 195 min to 90 min after completion of two doses. This retrospective, observational cohort study examined 73 patients who received daratumumab in the outpatient setting between December 2015 and April 2020. Patients were included if they were 18 years or older, had an International Classification of Disease (ICD)-10 diagnosis code for multiple myeloma, and received daratumumab intravenously. The primary outcome was a comparison of IRRs between those who did and did not receive montelukast. Secondary outcomes included IRR symptoms, rescue medications utilized for IRRs, and rapid rate administration outcomes. Montelukast use was associated with a lower rate of IRRs (44.4% vs. 65.2%, p = 0.044). Pulmonary IRR symptoms were more common in those who did not receive montelukast. Rapid rate administration of daratumumab did not lead to any IRRs. Adding montelukast as a pre-medication for daratumumab infusions led to a reduction in IRRs, and rapid rate administration was found to be safe after completion of two full doses of daratumumab.

A Retrospective Analysis of Psychiatric Presurgical Evaluation of Children and Adolescents Evaluated for Epilepsy Surgery in a Comprehensive Epilepsy Care Unit of Mumbai

Background Epilepsy being one of the most prevalent neurological diseases in children is associated with psychopathology and academic concerns. Epilepsy surgery is considered for refractory epilepsy at some centers in India and hence this study was undertaken to find out prevalence and type of psychopathology in children and adolescents with refractory epilepsy before epilepsy surgery. Methods All data were analyzed from the records of patients undergoing preepilepsy surgery protocol workup in comprehensive center of epilepsy care at a general municipal hospital in Mumbai. A record of 150 children and adolescents in the age group of 3 to 18 years over a period of 10 years was taken and all details of demographics, epilepsy, and psychopathology were recorded. Results The mean age for our sample was 11.4 ± 3.4 years and a male preponderance was seen. Majority (80%) of the children were pursuing education. The duration of seizure disorder was approximately 4.41 + 2.36 years and complex partial seizures were seen commonly in 50% of the children. Both magnetic resonance imaging (MRI) and video electroencephalography (VEEG) findings revealed right sided lateralization followed by left in majority of the patients. Psychopathology was seen in 70 (46%) patients with mental retardation, hyperkinetic disorders affecting attention and activity and oppositional defiant disorder, and unspecified mental disorder due to underlying brain damage being the type of International Classification of Disease-10th Revision (ICD-10) disorders seen. Patients with psychopathology showed a left-sided predominance on their MRI and VEEG findings for laterality of the epileptogenic focus as compared with right side. Conclusion Refractory seizures and associated psychopathology impact family life, friendships, and academics and worsen prognosis and quality of life. Screening for psychopathology in children with epilepsy would therefore lead to better outcomes especially prior to epilepsy surgery.

Frailty and In-Hospital Mortality Risk Using EHR Nursing Data

Purpose The purpose of this study was to evaluate four definitions of a Frailty Risk Score (FRS) derived from EHR data that includes combinations of biopsychosocial risk factors using nursing flowsheet data or International Classification of Disease, 10th revision (ICD-10) codes and blood biomarkers and its predictive properties for in-hospital mortality in adults ≥50 years admitted to medical-surgical units. Methods In this retrospective observational study and secondary analysis of an EHR dataset, survival analysis and Cox regression models were performed with sociodemographic and clinical covariates. Integrated area under the ROC curve (iAUC) across follow-up time based on Cox modeling was estimated. Results The 46,645 patients averaged 1.5 hospitalizations (SD = 1.1) over the study period and 63.3% were emergent admissions. The average age was 70.4 years (SD = 11.4), 55.3% were female, 73.0% were non-Hispanic White (73.0%), mean comorbidity score was 3.9 (SD = 2.9), 80.5% were taking 1.5 high risk medications, and 42% recorded polypharmacy. The best performing FRS-NF-26-LABS included nursing flowsheet data and blood biomarkers (Adj. HR = 1.30, 95% CI [1.28, 1.33]), with good accuracy (iAUC = .794); the reduced model with age, sex, and FRS only demonstrated similar accuracy. The poorest performance was the ICD-10 code-based FRS. Conclusion The FRS captures information about the patient that increases risk for in-hospital mortality not accounted for by other factors. Identification of frailty enables providers to enhance various aspects of care, including increased monitoring, applying more intensive, individualized resources, and initiating more informed discussions about treatments and discharge planning.

Early Dental Caries and Their Associated International Classifications of Disease Morbidity: A 16-Year Population Study

Objective: The study objective was to examine the relationship between dental caries diagnosed before the age of four and ICD diseases over a 16-year period. Methods: The sample of approximately 33,531 (48% female) individuals having a total of 2,864,790 physician diagnoses over 16 years comprised a the cohort two groups, one with (2.7% of the sample) and one without dental caries (dependent variable) that were under the age of four years in the first two years of the sample data. Categories of dental caries and associated gingivitis and periodontal disease were based on the International Classification of Disease (ICD Version 9) diagnostic codes 521-523. The sample was described. Odds ratios comparing those with and without dental caries and the main ICD classes were calculated. Additionally, the ratio of each ICD diagnosis frequency comparing the cohort groups were calculated and represented the diagnoses assigned over the first 15 physician visits. Results: Males had proportionally more dental caries diagnosed. Diagnoses were made predominantly by general practitioners. Within the dental caries cohort group, associated ICD diagnoses were over-represented in both odds ratios and within individual ICD diagnoses on the first diagnosis and over the first 15 diagnoses in time. Conclusion: Dental caries diagnosed in very young children before the age of four are associated with multi-morbidity over subsequent years. Sex differences and patterns of associated morbidity may contribute to a better understanding of early life vulnerability to dental caries and their sequelae.

ZUSAMMENFASSUNGNach jahrzehnteübergreifender Diskussion über die nosologische Einordnung unkontrollierbaren exzessiven Sexualverhaltens, ist die Einführung der Diagnose des zwanghaften Sexualverhaltens für die kommende Ausgabe der International Classification of Disease (ICD-11) geplant. Auch wenn die Zuordnung zur Kategorie der Impulskontrollstörungen etwas widersprüchlich erscheint, ist nach unserem Erachten ein notwendiger Schritt erfolgt. Mit einer kommenden eigenständigen Kategorie wird es möglich sein, zwanghaftes Sexualverhalten diagnostisch zu klassifizieren, welches häufig klinisch relevantes Leid verursacht. Im vorliegenden Artikel stellen wir die Definition des zwanghaften Sexualverhaltens vor sowie Prävalenzschätzungen und zeigen eine mögliche Ätiologie auf. Weiterhin werden die Diagnostik und Grundlagen einer möglichen Psychotherapie und Pharmakotherapie vorgestellt.

106. Risk Classification to Differentiate Autoimmune from Viral Encephalitis

Background Autoimmune encephalitis is an urgent treatable etiology that needs to be differentiated from viral encephalitis. Prompt recognition and therapy is of utmost importance. Methods We performed a retrospective cohort of encephalitis cases in 16 hospitals in Houston, Texas, between January 2005 and December 2019. Results A total of 1,310 adult (age ≥18 years) inpatient hospital admissions were identified by the presence of an encephalitis-related discharge diagnosis per the International Classification of Disease 9th edition codes. Of these, only 279 cases met the 2013 International Encephalitis Consortium criteria for probable encephalitis. A laboratory confirmed diagnosis of autoimmune encephalitis or viral encephalitis was identified in 36 (12.9%) and 88 (31.5%) cases, respectively. There were 155 cases (55.5%) that had no identifiable cause and were considered idiopathic. As compared to viral encephalitis, patients with autoimmune encephalitis were more likely to be younger (< 60 years old), have a subacute (6-30 days) or chronic ( >30 days) presentation, have seizures, and have psychiatric and/or memory complaints (P< 0.001). Furthermore, patients with autoimmune encephalitis were less likely to be febrile and to lack inflammatory cerebrospinal fluid (CSF) (defined as white blood cells < 50 per microliter or protein < 50 milligrams per deciliter) [See Table 1]. In the multivariable logistic regression model, subacute/chronic presentation, psychiatric and/or memory complaints, and lack of inflammatory CSF were significantly associated with autoimmune encephalitis. Using these 3 variables, patients were classified into 3 risk categories for autoimmune encephalitis: low risk (0-1 variables); 0%; intermediate risk (2 variables); 16%; and high risk (3 variables); 83% (P value < 0.001). Conclusion Adults with encephalitis can be accurately stratified for the risk of having autoimmune encephalitis using clinical variables available upon presentation.

Narrow Specificity of Pessimistic Attribution Style and other Attribution Styles in Clinically Diagnosed Anxiety Disorders: A Systematic Review

Objective: Research has established that cognitive vulnerability has a role in mood disorder. Researchers have taken a keen interest in exploring the role of pessimistic attribution style (PAS) found in depression, expecting that it can also explain comorbid disorders to depression. The objectives of this systematic review are to explore the narrow specificity of PAS, and to search for other attribution style, if any, in anxiety disorders. Method: PubMed, Research4Life and APA PsycArticles® databases were searched for relevant articles recorded up to May 18, 2021. All published empirical articles, systematic review or meta-analysis, which included at least any of the anxiety disorders diagnosed using Diagnostic and Statistical Manual (DSM, APA) or International Classification of Disease (ICD, WHO) in the context of attribution bias, were included. Title, abstract and methodology of the publications were screened for potential selection. Risk of bias in the reviewed articles was assessed using the GRADE system. Result: Total 628 records were screened, out of which 19 were found eligible for inclusion. Result suggests narrow specificity of PAS has limited evidence and studies lack a rigorous methodology to establish it. Conclusion: There is indication that various attribution biases can be present in different anxiety disorders including those reported in depression.

Diagnosed or prescribed only? A national analysis of initial evaluation and management of insomnia among older adult Medicare beneficiaries

Study Objectives To describe initial insomnia-related encounters among a national sample of Medicare beneficiaries, and to identify older adults at risk for potentially inappropriate prescription insomnia medication usage. Methods Our data source was a random 5% sample of Medicare administrative claims data (2006-2013). Insomnia was operationalized as International Classification of Disease, Ninth Revision, Clinical Modification diagnostic codes. Insomnia medications included FDA-approved insomnia-related medication classes and drugs. Logistic regression was employed to identify predictors of being “prescribed only” (i.e., being prescribed an insomnia medication without a corresponding insomnia diagnosis). Results A total of N=60,362 beneficiaries received either an insomnia diagnosis or a prescription for an insomnia medication as their first sleep-related encounter during the study period. Of these, 55.1% (n=33,245) were prescribed only, whereas 44.9% (n=27,117) received a concurrent insomnia diagnosis. In a fully adjusted regression model, younger age (odds ratio (OR) 0.98; 95% confidence interval (CI) 0.98, 0.99), male sex (OR 1.15; 95% CI 1.11, 1.20), and several comorbid conditions (i.e., dementia [OR 1.21; 95% CI 1.15, 1.27] and anemia [OR 1.17; 95% CI 1.13, 1.22]) were positively associated with being prescribed only. Conversely, black individuals (OR 0.83; 95% CI 0.78, 0.89) and those of “other” race (OR 0.89; 95% CI 0.84, 0.94) were less likely to be prescribed only. Individuals who received care from a board-certified sleep medicine provider (BCSMP) were less likely to be prescribed only (OR 0.27; 95% CI 0.16, 0.46). Conclusions Fewer than half of Medicare beneficiaries prescribed insomnia medications ever received a formal sleep-related diagnosis.
