A Comparison of Patients' and Neurologists' Assessments of their Teleneurology Encounter: A Cross-Sectional Analysis.

Background and Objectives: To better understand patients' and neurologists' assessments of their experiences regarding effectiveness of teleneurology encounters. Methods: Following an audio-video telehealth visit, neurologists asked patients to participate in a survey-based research study about the encounter, and then, the neurologists also recorded their own evaluations. Data were analyzed using standard quantitative and qualitative techniques for dichotomous and ordered-category survey responses in this cross-sectional analysis. Results: The study included unique encounters between 187 patients and 11 general neurologists. The mean patient age was 49 ± 17.5 years. Two thirds of the patients (66.8%, 125/187) were female. One third (33.2%; 62) were patients new to the NYU Langone Health neurology practices. The most common patient chief complaints were headache (69/187, 36.9%), focal and generalized numbness or tingling (21, 11.2%), memory difficulty (15, 8%), spine-related symptoms (12, 6.4%), and vertigo (11, 5.9%). Most patients (94.7%, 177/187) reported that the teleneurology encounter satisfied their needs. Patients and their neurologists agreed that the experience was effective in 91% (162/178) of encounters, regardless of whether the visit was for a new or established patient visit. Discussion: More than 90% of new and established patients and their neurologists agreed that teleneurology encounters were effective despite some limitations of the examination, the occasional need for patient assistance, and technical difficulties. Our results provide further evidence to justify and to expand the clinical use of teleneurology.

Neurologists' Evaluations of Experience and Effectiveness of Teleneurology Encounters.

Background and Objectives: To better understand neurologists' assessments of the experiences and effectiveness of teleneurology encounters. Methods: After completing an audio-video telehealth visit with verbally consenting patients, neurologists recorded their evaluations of the encounter. Data were analyzed using standard quantitative and qualitative techniques. Results: The study included unique encounters between 187 patients and 11 neurologists. The mean patient age was 49 ± 17.5 years. Two thirds of patients (66.8%, 125/187) were female. One third of patients (33.2%; 62) were new patients. The most common patient complaints were headache (69/187, 36.9%), focal and generalized numbness or tingling (21, 11.2%), memory difficulty (15, 8%), spine-related symptoms (12, 6.4%), and vertigo (11, 5.9%). Neurologists reported that they completed a virtual examination that provided enough information for medical decision-making in 94.9% of encounters (169/178, 9 missing responses). Fourteen of 25 examination elements important for medical decision-making could be performed sufficiently during virtual encounters. Examination assistance was needed for 16.4% (30/183) of patients, who were, on average, 17.3 years older than those who did not require assistance (62.9 years vs. 45.6 years, p = 0.0002). In 19.1% (34/178) of encounters, neurologists learned clinically relevant information from seeing patients in their homes. Neurologists' assessments of the effectiveness of encounters were not related to the presence (97.2%, 35/36 effective) or absence (95%, 134/141 effective) of technical difficulties (p = 0.5729) in 177 encounters (10 missing responses). Discussion: Neurologists reported that nearly 95% of teleneurology encounters were effective despite limitations of the virtual examination, occasional need for patient assistance, and technical difficulties.

Meaningful response criteria for myelodysplastic syndromes.

Standardizing response criteria for myelodysplastic syndromes (MDS), a clinically and biologically heterogeneous group of disorders, has been historically challenging. The International Working Group (IWG) response criteria, first proposed in 2000 and modified in 2006 and 2018, represent the best effort by a group of international experts to define a set of clinically meaningful end-points in MDS. These criteria have been adopted in many MDS clinical trials, allowing for comparisons of response across trials. However, clinical experience has also revealed some limitations of these criteria, and most of the end-points proposed by the IWG require further validation. In this review, we present a critical analysis of the current MDS response criteria from both a practical standpoint and based on currently available clinical trial data. Potential areas for improvement in the criteria are highlighted, which may be considered in future iterations of the response criteria.

Incidence and prevalence of psoriatic arthritis in patients with psoriasis stratified by psoriasis disease severity: Retrospective analysis of an electronic health records database in the United States.

BACKGROUND: Among patients in the United States with psoriasis (PsO), limited data exist on the incidence and prevalence of psoriatic arthritis (PsA) based on disease severity. OBJECTIVE: To assess the incidence, prevalence, and predictors of PsA among patients with PsO stratified by PsO severity using treatment type. METHODS: Incidence of PsA per 100 PsO patient-years (PY) and prevalence were assessed using the Optum electronic health records database. Incidence was assessed from PsO diagnosis and 1 year after PsO diagnosis overall and stratified by mutually exclusive treatment classes as a severity surrogate. RESULTS: The overall incidence of PsA was 2.9 (95% CI, 2.9-3.0) events per 100 PY. The incidence (95% CI) by severity surrogate was 2.1 (2.1-2.1), 9.9 (9.5-10.4), and 17.6 (16.9-18.3) events per 100 PY for patients with mild, moderate, and severe PsO as determined by receiving nonsystemics, nonbiologic systemic therapy, and biologics, respectively. When excluding patients diagnosed with PsA 1 year after PsO diagnosis, overall incidence was lower (1.7 [95% CI, 1.6-1.7] events per 100 PY), with similar trends for treatment-severity surrogates. LIMITATIONS: Results may not be generalizable to a wider population. CONCLUSION: The risk of developing PsA increased with disease severity and was highest in patients with the most severe PsO.

Lipoxin B4 Enhances Human Memory B Cell Antibody Production via Upregulating Cyclooxygenase-2 Expression.

Vaccination has been the most effective way to prevent or reduce infectious diseases; examples include the eradication of smallpox and attenuation of tetanus and measles. However, there is a large segment of the population that responds poorly to vaccines, in part because they are immunocompromised because of disease, age, or pharmacologic therapy and are unable to generate long-term protection. Specialized proresolving mediators are endogenously produced lipids that have potent proresolving and anti-inflammatory activities. Lipoxin B4 (LXB4) is a member of the lipoxin family, with its proresolving effects shown in allergic airway inflammation. However, its effects on the adaptive immune system, especially on human B cells, are not known. In this study, we investigated the effects of LXB4 on human B cells using cells from healthy donors and donors vaccinated against influenza virus in vitro. LXB4 promoted IgG Ab production in memory B cells and also increased the number of IgG-secreting B cells. LXB4 enhanced expression of two key transcription factors involved in plasma cell differentiation, BLIMP1 and XBP1. Interestingly, LXB4 increased expression of cyclooxygenase-2 (COX2), an enzyme that is required for efficient B cell Ab production. The effects of LXB4 are at least partially COX2-dependent as COX2 inhibitors attenuated LXB4-stimulated BLIMP1 and Xpb-1 expression as well as IgG production. Thus, our study reveals for the first time, to our knowledge, that LXB4 boosts memory B cell activation through COX2 and suggests that LXB4 can serve as a new vaccine adjuvant.

Specialized proresolving mediators (SPMs) inhibit human B-cell IgE production.

Specialized proresolving mediators (SPMs) constitute a recently recognized class of bioactive molecules thatpromote the resolution of inflammation. We recently reported that the SPMs resolvin D1 (RvD1) and 17-hydroxydocosahexaenoic acid (17-HDHA) promote the differentiation of IgG-secreting B cells and enhance antibody-mediated immune responses. However, there is an important knowledge gap regarding whether or not SPMs regulate human B-cell IgE production, which is the key effector in diseases such as asthma and allergy. Therefore, we investigated whether a panel of diverse SPMs influences B-cell IgE production. An important finding was that 17-HDHA and RvD1 inhibit IgE production by human B cells and suppress the differentiation of naïve B cells into IgE-secreting cells by specifically blocking epsilon germline transcript. This effect is specific to human IgE, as the SPMs do not inhibit production of IgM and IgG and did not suppress other IL-4-upregulated genes. 17-HDHA and RvD1 act by stabilizing the transcriptional repressor B-cell lymphoma 6, which competes with STAT6 for binding at the epsilon germline transcript promoter. Overall, these new findings demonstrate that certain SPMs inhibit the differentiation of IgE-producing B cells, without being broadly immune suppressive, representing a novel class of potential therapeutics for IgE-driven diseases such as asthma and allergy.

The specialized proresolving mediator 17-HDHA enhances the antibody-mediated immune response against influenza virus: a new class of adjuvant?

Influenza viruses remain a critical global health concern. More efficacious vaccines are needed to protect against influenza virus, yet few adjuvants are approved for routine use. Specialized proresolving mediators (SPMs) are powerful endogenous bioactive regulators of inflammation, with great clinical translational properties. In this study, we investigated the ability of the SPM 17-HDHA to enhance the adaptive immune response using an OVA immunization model and a preclinical influenza vaccination mouse model. Our findings revealed that mice immunized with OVA plus 17-HDHA or with H1N1-derived HA protein plus 17-HDHA increased Ag-specific Ab titers. 17-HDHA increased the number of Ab-secreting cells in vitro and the number of HA-specific Ab-secreting cells present in the bone marrow. Importantly, the 17-HDHA-mediated increased Ab production was more protective against live pH1N1 influenza infection in mice. To our knowledge, this is the first report on the biological effects of ω-3-derived SPMs on the humoral immune response. These findings illustrate a previously unknown biological link between proresolution signals and the adaptive immune system. Furthermore, this work has important implications for the understanding of B cell biology, as well as the development of new potential vaccine adjuvants.

Macrophages clear refrigerator storage-damaged red blood cells and subsequently secrete cytokines in vivo, but not in vitro, in a murine model.

BACKGROUND: In mice, refrigerator-stored red blood cells (RBCs) are cleared by extravascular hemolysis and induce cytokine production. To enhance understanding of this phenomenon, we sought to model it in vitro. STUDY DESIGN AND METHODS: Ingestion of refrigerator-stored murine RBCs and subsequent cytokine production were studied using J774A.1 mouse macrophage cells and primary murine splenic macrophages. Wild-type and Ccl2-GFP reporter mice were used for RBC clearance in vivo. RESULTS: Although J774A.1 cells and primary macrophages preferentially ingested refrigerator-stored RBCs in vitro, compared to freshly isolated RBCs, neither produced increased cytokines after erythrophagocytosis. In contrast, phagocytosis of refrigerator-stored RBCs in vivo induced increases in circulating monocyte chemoattractant protein-1 (MCP-1) and keratinocyte chemoattractant (KC) and correspondingly increased mRNA levels in mouse spleen and liver. In the spleen, these were predominantly expressed by CD11b+ cells. Using Ccl2-GFP reporter mice, the predominant splenic population responsible for MCP-1 mRNA production was tissue-resident macrophages (i.e., CD45+, CD11b+, F4/80+, Ly6c+, and CD11c(low) cells). CONCLUSION: J774A.1 cells and primary macrophages selectively ingested refrigerator-stored RBCs by phagocytosis. Although cytokine expression was not enhanced, this approach could be used to identify the relevant receptor-ligand combination(s). In contrast, cytokine levels increased after phagocytosis of refrigerator-stored RBCs in vivo. These were primarily cleared in the liver and spleen, which demonstrated increased MCP-1 and KC mRNA expression. Finally, in mouse spleen, tissue-resident macrophages were predominantly involved in MCP-1 mRNA production. The differences between cytokine production in vitro and in vivo are not yet well understood.

Prognostic Understanding, Goals of Care, and Quality of Life in Hospitalized Patients with Leukemia or Multiple Myeloma.

Background: Prior studies reveal a lack of illness understanding and prognostic awareness among patients with hematological malignancies. We evaluated prognostic awareness and illness understanding among patients with acute leukemia and multiple myeloma (MM) and measured patient-hematologist discordance. Methods: We prospectively enrolled patients with acute leukemia and MM at Mount Sinai Hospital or Yale New Haven Hospital between August 2015 and February 2020. Patients were administered a survey assessing prognostic awareness, goals of care (GOC), and quality of life. Hematologists completed a similar survey for each patient. We assessed discordance across the cohort of patients and hematologists using the likelihood-ratio chi-square test and within patient-hematologist pairs using the kappa (κ) statistic. Results: We enrolled 185 patients (137 with leukemia and 48 with MM) and 29 hematologists. Among patients, 137 (74%) self-identified as White, 27 (15%) as Black, and 21 (11%) as Hispanic. Across the entire cohort, patients were significantly more optimistic about treatment goals compared with hematologists (p = 0.027). Within patient-hematologist pairs, hematologists were significantly more optimistic than patients with respect to line of treatment (κ = 0.03). For both leukemia and MM cohorts, patients were significantly more likely to respond "don't know" or deferring to a faith-based response with 88 (64%) and 34 (71%), respectively, compared with only 28 (20%) and 11 (23%) of hematologists, respectively. Conclusions: We observed significant discordance regarding prognosis and GOC among patients with hematological malignancies and their hematologists. These data support future interventions to improve prognostic understanding among this patient population to facilitate informed treatment choices.

Patient perspectives on BCMA-targeted therapies for multiple myeloma: a survey conducted in a patient advocacy group.

Background: Advances in multiple myeloma (MM) treatment have shifted the therapeutic landscape. Understanding patients' perspectives can assist physicians in helping patients make informed decisions. This study aimed to understand the patient decision-making process and gain insights into patient perspectives on B-cell maturation antigen (BCMA)-targeted therapies for MM. Methods: An 18-question survey was completed by patients with MM enrolled in HealthTree® Cure Hub, an online portal helping patients with plasma cell dyscrasias navigate their disease. Results: From October 28, 2022, to January 12, 2023, 325 patients with MM participated in the survey. The mean age (standard deviation) of the respondents was 66 (8) years; 54% were female and 90% were White. Among 218 patients with complete clinical records in the database, the median (min, max) lines of therapy (LOT) was 2 (1,16). Among 61 (28%) patients who had received ≥4 LOTs, 55 (90%) were triple-class exposed. Of the 290 patients who responded to the question about openness to new therapies, 76 (26%) were open to trying a new therapy immediately and 125 (43%) wanted more information on safety and efficacy. Most respondents reported likely or very likely to try a BCMA CAR T-cell therapy (60%) or a bispecific antibody (74%) and some needed more information to decide (16% for CAR T-cell therapy and 13% for bispecific antibody). The most requested information included efficacy, side effects (SEs), eligibility, and administration process for both CAR T-cell and bispecific therapies. When 2 therapies with the same efficacy and duration of response were offered, 69% of respondents would prefer the therapy with a lower risk of severe SEs but requires continuous dosing with no treatment-free interval, and 31% preferred a therapy given once followed by a treatment-free interval but with a potentially higher risk of severe SEs. To receive an effective therapy, the top acceptable trade-offs included frequent monitoring of SEs and initiating a new therapy in a hospital setting, and the least acceptable compromise was caregiver burden. Conclusions: This study found a high level of openness in patients with MM to try BCMA-targeted therapies. Information on efficacy, safety, availability, and eligibility may assist patients on decision-making.

Panel Interview of ONcology practices with Emergent Experience of teclistamab in the Real world: the TecPIONEER Study.

OBJECTIVE: To understand clinicians' current teclistamab step-up dosing (SUD) model and how they envision future administration models, as well as perceived barriers and facilitators to these models in day-to-day clinical practice. METHODS: Interviews of clinicians with RW experience administering teclistamab, with a subsequent roundtable discussion to discuss interview findings. Topics of interest included managing adverse events (AE), and handling logistics of SUD and transition of care (ToC). RESULTS: 20 clinicians representing 19 practices participated. Of 14 practices administering inpatient teclistamab SUD, 12 (86%) utilized a single admission. A day 1-3-5 dosing schedule with a 7-day length of stay was planned in 10/14 (71%). The remaining 5 practices employed outpatient or hybrid SUD. SUD models depended on cellular therapy experience, patient volume, and monitoring capabilities. Clinicians desired to administer SUD outpatient for convenience and reduced healthcare resource use. 11% of practices reported using tocilizumab for cytokine release syndrome (CRS) prophylaxis, whilst it was uniformly used to treat grade 2+ CRS. Corticosteroids were the preferred treatment for neurotoxicity. Infection prophylaxis with intravenous immunoglobulin was reported by 89% of practices. Patient- and institution-level factors affected decision-making of transitioning patients back to referring sites after SUD. CONCLUSION: The results consolidated practice-based experiences and indicated diverse RW SUD models and patient management strategies in practices with familiarity with teclistamab AE management and ToC protocols. Inpatient SUD is common, with expectations that approaches will evolve toward outpatient or community-based administration. Further research is needed to investigate outcomes of different care models and AE management strategies.

Multiple myeloma is a blood cancer that forms in plasma cells. Teclistamab is a new treatment for patients with multiple myeloma who have received prior treatment but for whom their multiple myeloma has come back or stopped responding to treatment multiple times. Because teclistamab works differently than other existing multiple myeloma treatments, there is a need to understand how oncologists who have experience with teclistamab are managing their patients in order to inform best practices for use by more healthcare providers. We interviewed oncologists that treat patients with multiple myeloma to understand their experiences with teclistamab, including how they manage initial dosing (step-up dosing) processes, treat adverse events, and transition patients to outpatient or external clinics for continued care. Most practices were administering step-up dosing of teclistamab in an inpatient setting soon after teclistamab became a treatment option, with a high level of desire to move the initial dosing to an outpatient setting in the near future. Those that were already administering step-up dosing in an outpatient setting had models unique to their practice. Oncologists described numerous processes for monitoring and managing adverse events of the treatment, including treating patients with preventative medications and regularly monitoring vital signs throughout step-up dosing. Oncologists expected that their teclistamab administration processes will likely evolve over time as they gain more familiarity with the treatment, and will need to consider patient-level factors to administer step-up dosing in an outpatient setting.

Chronic hepatitis B and HIV coinfection.

Hepatitis B virus (HBV) infection is common among people with HIV owing to shared modes of viral transmission. Compared with individuals with HBV infection alone, people with HIV/HBV coinfection experience an accelerated progression of liver disease, including increased risks for hepatocellular carcinoma, liver-related mortality, and all-cause mortality. Therefore, HBV screening and appropriate treatment are crucial for people with HIV. This article reviews the epidemiology, natural history, and management of HIV/HBV coinfection, as well as recommendations for prevention of HBV infection among people with HIV.

Burden of illness associated with overweight and obesity in patients hospitalized with COVID-19 in the United States: analysis of the premier healthcare database from April 1, 2020 to October 31, 2020.

BACKGROUND: SARS-CoV-2 (COVID-19) continues to be a major public health issue. Obesity is a major risk factor for disease severity and mortality associated with COVID-19. OBJECTIVE: This study sought to estimate the healthcare resource use and cost outcomes in patients hospitalized with COVID-19 in the United States (US) according to body mass index (BMI) class. METHODS: Retrospective cross-sectional study analyzing data from the Premier Healthcare COVID-19 database for hospital length-of-stay (LOS), intensive care unit (ICU) admission, ICU LOS, invasive mechanical ventilator use, invasive mechanical ventilator use duration, in-hospital mortality, and total hospital costs from hospital charge data. RESULTS: After adjustment for patient age, gender, and race, patients with COVID-19 and overweight or obesity had longer durations for mean hospital LOS (normal BMI = 7.4 days, class 3 obesity = 9.4 days, p < .0001) and ICU LOS (normal BMI = 6.1 days, class 3 obesity = 9.5 days, p < .0001) than patients with normal weight. Patients with normal BMI had fewer days on invasive mechanical ventilation compared to patients with overweight and obesity classes 1-3 (6.7 days vs. 7.8, 10.1, 11.5, and 12.4, respectively, p < .0001). The predicted probability of in-hospital mortality was nearly twice that of patients with class 3 obesity compared to patients with normal BMI (15.0 vs 8.1%, p < .0001). Mean (standard deviation) total hospital costs for a patient with class 3 obesity is estimated at $26,545 ($24,433-$28,839), 1.5 times greater than the mean for a patient with a normal BMI at $17,588 ($16,298-$18,981). CONCLUSIONS: Increasing levels of BMI class, from overweight to obesity class 3, are significantly associated with higher levels of healthcare resource utilization and costs in adult patients hospitalized with COVID-19 in the US. Effective treatment of overweight and obesity are needed to reduce the burden of illness associated with COVID-19.

The COVID-19 pandemic has caused many people to be seriously ill. People who are overweight are more likely to get sicker from COVID-19 infection and to require hospitalization.In our study, we compared patients who have normal weight to people who have overweight or obesity to understand how excess weight affects their experiences with COVID-19. We looked at: (1) how overweight and obesity is related to how long patients with COVID-19 stay in the hospital, (2) if they stayed in the intensive care unit (ICU) and how long they spent there, (3) whether they needed help breathing with the use of a ventilator and how long they needed a ventilator, (4) if they died during their hospital stay, and (5) how much their hospital stay cost.We found that people who have overweight or obesity stayed in the hospital longer, were more likely to need to stay in the ICU, and were in the ICU longer. They were also more likely to need help breathing with the use of a ventilator and needed that help for a longer time. People who have overweight or obesity died during their hospital stay more often than people with a normal BMI. The costs associated with people who have overweight or obesity were higher than people who have a normal BMI.Overall, this study shows that having overweight or obesity is a significant risk factor for poor outcomes from COVID-19 infection. Treatment for obesity and overweight is needed to help improve outcomes from future pandemics.

The Relative Value of Anti-Obesity Medications Compared to Similar Therapies.

Purpose: To demonstrate a need for improved health insurance coverage for anti-obesity medications (AOMs) by comparing clinical and economic benefits of obesity treatments to covered medications for selected therapeutic areas. Methods: Using a grey literature search, we identified and prioritized therapeutic areas and treatment analogues for comparison to obesity. A targeted literature review identified clinical and economic outcomes research across the therapeutic area analogues. Associated comorbidities, clinical evidence, indirect costs (ie, absenteeism and productivity loss), and direct medical costs were evaluated to determine the relative value of treating obesity. Results: Four therapeutic areas/treatment analogues were selected for comparison to obesity: smoking cessation (varenicline), daytime sleepiness (modafinil), migraines (erenumab), and fibromyalgia (pregabalin). Obesity was associated with 17 comorbidities, more than migraine (9), smoking (8), daytime sleepiness (5), and fibromyalgia (2). Economic burden was greatest for obesity, followed by smoking, with yearly indirect and direct medical costs totaling $676 and $345 billion, respectively. AOMs resulted in cost savings of $2586 in direct medical costs per patient per year (PPPY), greater than that for varenicline at $930 PPPY, modafinil at $1045 PPPY, and erenumab at $468 PPPY; pregabalin utilization increased costs by $924 PPPY. AOMs were covered by 10-16% of United States health insurance plans, compared to 45-59% for the four comparators. Conclusion: Compared to four therapeutic analogues, obesity represented the highest economic burden and was associated with more comorbidities. AOMs provide greater cost savings compared to selected analogues. However, AOMs have limited formulary coverage. Improved coverage of AOMs may increase access to these treatments and may help address the clinical and economic burden associated with obesity and its comorbidities.

Development of an Assessment Tool for Completion by Patients with Overweight or Obesity.

INTRODUCTION: Discussions of weight-management strategies between patients and healthcare providers can yield positive outcomes for people with overweight or obesity. Nonetheless, people with overweight or obesity encounter communication challenges and other barriers to pursuing effective weight-management strategies with their healthcare providers. The aim of this study was to develop a new self-completed assessment tool to initiate and facilitate conversations related to weight management between patients and healthcare providers. METHODS: Developing the assessment tool involved a series of steps and draft versions of the tool, based on feedback from key opinion leaders in the field of obesity (N = 4) and input from people with overweight or obesity (N = 18). Three iterative rounds of qualitative interviews were conducted in the USA. A targeted review of prior qualitative research was conducted to identify common and important impacts of obesity on patients' functioning. Standard qualitative analytical methods were used to identify concepts of importance in a concept elicitation exercise during the interviews and were evaluated for potential inclusion in the tool. Potential problems with the tool were flagged during cognitive debriefing of the draft tool. RESULTS: During 18 individual interviews, participants referenced the impact of their weight on their lives, including health and comorbidities, physical function, emotional/mental functioning, social life, and physical appearance. Over the course of the tool's development, 24 common and important impacts of obesity on patients' functioning were reduced to a final set of eight concepts in the final tool that were deemed important and relevant to both patients and key opinion leaders. CONCLUSIONS: The assessment tool is a five-item, self-completed measure expected to foster patient self-advocacy for individuals with overweight or obesity by giving them an opportunity to define their weight-management goals and discuss these, along with various medical interventions, with a healthcare provider.

Considerations for Drug Development in Myelodysplastic Syndromes.

Myelodysplastic syndromes (MDS) have historically been challenging diseases for drug development due to their biology, preclinical modeling, and the affected patient population. In April 2022, the FDA convened a panel of regulators and academic experts in MDS to discuss approaches to improve MDS drug development. The panel reviewed challenges in MDS clinical trial design and endpoints and outlined considerations for future trial design in MDS to facilitate drug development to meaningfully meet patient needs. Challenges for defining clinical benefit in patients with MDS include cumbersome response criteria, standardized transfusion thresholds, and application and validation of patient reported outcome instruments. Clinical trials should reflect the biology of disease evolution, the advanced age of patients with MDS, and how patients are treated in real-world settings to maximize the likelihood of identifying active drugs. In patients with lower-risk disease, response criteria for anemic patients should be based on baseline transfusion dependency, improvement in symptoms, and quality of life. For higher-risk patients with MDS, trials should include guidance to prevent dose reductions or delays that could limit efficacy, specify minimal durations of treatment (in the absence of toxicity or progression), and have endpoints focused on overall survival and durable responses. MDS trials should be designed from the outset to allow the practicable application of new therapies in this high-needs population, with drugs that can be administered and tolerated in community settings, and with endpoints that meaningfully improve patients' lives over existing therapies.

Clinical and Cost Benefits of Anti-Obesity Medication for US Veterans Participating in the MOVE! Weight Management Program.

Abstract This study investigated the clinical and economic impact of anti-obesity medications (AOMs; orlistat, liraglutide, phentermine/topiramate extended-release [ER], naltrexone ER/bupropion ER) among United States Veterans with obesity participating in Motivating Overweight/Obese Veterans Everywhere! (MOVE!), a government-initiated weight management program. The study population was identified from electronic medical records of the Veterans Health Administration (2010-2020). Clinical indices of obesity and health care resource utilization and costs were evaluated at 6, 12, and 24 months after the initial dispensing of an AOM in the AOM+MOVE! cohort (N = 3732, mean age 57 years, 79% male) or on the corresponding date of an inpatient or outpatient encounter in the MOVE! cohort (N = 7883, mean age 58 years, 81% male). At 6 months postindex, the AOM+MOVE! cohort had better cardiometabolic indices (eg, systolic blood pressure, diastolic blood pressure, total cholesterol, low-density lipoprotein cholesterol, hemoglobin A1c) than the MOVE! cohort, with the trends persisting at 12 and 24 months. The AOM+MOVE! cohort was significantly more likely than the MOVE! cohort to have weight decreases of 5%-10%, 10%-15%, and >15% and lower body mass index at 6, 12, and 24 months. The AOM+MOVE! cohort also had fewer inpatient and emergency department visits than the MOVE! cohort, which was associated with lower mean total medical costs including inpatient costs. These results suggest that combining AOM treatment with the MOVE! program could yield long-term cost savings for the Veterans Affairs network and meaningful clinical improvements for Veterans with obesity.

Comparison of Clinical Manifestations in Rheumatoid Arthritis vs. Spondyloarthritis: A Systematic Literature Review.

INTRODUCTION: Misclassification of spondyloarthritis (SpA) as rheumatoid arthritis (RA) may lead to delayed SpA diagnosis and suboptimal therapeutic outcomes. Here, we evaluate the literature on clinical manifestations in patients with SpA and RA, particularly seronegative RA, to understand the potential overlap, distinctions, and most reliable approaches to accurate diagnosis. METHODS: In this systematic literature review, conducted according to PRISMA guidelines, we searched key biomedical databases for English-language publications of original research articles (up to July 23, 2020) and rheumatology conference abstracts (January 1, 2018-July 31, 2020) reporting key SpA clinical presentations in patients with SpA or RA. Publications were assessed for eligibility by two independent reviewers; discrepancies were resolved by a third. Studies were evaluated for publication quality using the Downs and Black checklist. RESULTS: Of 4712 records retrieved, 79 met the inclusion criteria and were included in the analysis. Of these, 54 included study populations with SpA and RA, and 25 with seropositive and/or seronegative RA. Entheseal abnormalities were more frequently reported among patients with SpA than RA and with seronegative vs. seropositive RA. Psoriasis, nail psoriasis, and dactylitis were exclusively seen in SpA vs. RA. In most publications (70 of 79), advanced imaging techniques allowed for more accurate distinction between SpA and RA. Overlapping clinical characteristics occur in SpA and RA, including inflammation and destruction of joints, pain, diminished functional ability, and increased risk for comorbidities. However, of 54 studies comparing SpA and RA populations, only seven concluded that no distinction can be made based on the SpA manifestations and outcomes examined. CONCLUSIONS: Typical SpA-related clinical symptoms and signs were observed in patients with RA, suggesting that misclassification could occur. Availability of advanced imaging modalities may allow for more prompt and comprehensive evaluation of peripheral manifestations in SpA and RA, reducing misclassification and delayed diagnosis.

Spondyloarthritis (SpA) is a group of chronic, inflammatory diseases that includes axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA), in addition to other peripheral forms of SpA. AxSpA primarily affects the spine and can cause chronic back pain. PsA occurs in patients with the skin condition psoriasis and patients often experience symptoms including joint pain, stiffness, and swelling. Quick and accurate diagnosis of SpA is necessary to prevent joint damage and physical limitations. Rheumatoid arthritis (RA) is characterized by pain, swelling, and stiffness in multiple joints, and delayed diagnosis and treatment can have lasting effects. However, many patients with SpA and RA who initially seek medical care often experience delayed diagnoses. This study evaluated the literature on symptoms in patients with SpA and RA, particularly patients with RA without antibodies typically associated with the disease, to understand the potential overlap, differences, and most reliable ways to accurately diagnose patients. Data from 79 records were included in the analysis, 54 of which included study populations with SpA and RA. Skin and nail psoriasis, as well as swelling of the fingers and toes, was only seen in patients with SpA. Most studies showed that enhanced imaging allowed for distinguishing between SpA and RA. This study showed that typical signs and symptoms of SpA, including inflammation and joint pain, could also be seen in patients with RA, which suggests that challenges exist for accurately identifying SpA. This highlights the importance of advanced imaging to diagnose and treat patients with SpA in a timely manner.

Economic outcomes of antiobesity medication use among adults in the United States: A retrospective cohort study.

BACKGROUND: Obesity prevalence exceeds 40% in the US adult population, posing a substantial burden on the health care system. Antiobesity medication (AOM) is recommended for obesity management. However, little evidence exists estimating the economic impact of AOMs on health care costs over time. OBJECTIVE: To estimate the impact of AOMs indicated for long-term therapy on shortterm direct medical costs, by obesity class, in a commercially insured population. METHODS: For this retrospective cohort study, we used the IBM MarketScan Commercial Claims and Encounters Database to capture health care utilization between January 1, 2015, and December 31, 2019. Adults aged 18-63 years with a body mass index greater than or equal to 30 kg/m2 were categorized into 2 cohorts based on new AOM usage at cohort entry. New AOM users were taking 1 of 4 AOMs currently approved by the US Food and Drug Administration for long-term therapy, with greater than 112 days supply of medicine within 12 months after treatment initiation. AOM nonusers were those not taking an AOM indicated for long-term therapy during the baseline or follow-up period. We used difference-in-differences estimation to calculate the change in average annual total health care costs and cost of medications (excluding AOMs) over a 2-year follow-up period using inverse probability of treatment-weighted estimates. RESULTS: The study population included 219,971 patients, 1,405 AOM users and 218,566 AOM nonusers. Over 2 years, patients on treatment were more than twice as likely to be classified into a lower obesity class than AOM nonusers. Although the average yearly direct cost of care increased for both treatment groups in the first year of follow-up, by year 2, costs for untreated patients continued to rise while costs for patients on therapy remained stable or declined. The difference-in-differences of medication cost (excluding AOMs) and total health care cost (excluding AOMs) across all 3 obesity classes in year 2 ranged from $1,321 to $1,952 and $1,323 to $2,766, respectively, indicating a cost savings. Total cost of care, inclusive of AOMs, followed a similar trend. CONCLUSIONS: Use of AOMs is associated with the odds of moving to a lower obesity class and a general stabilization or reduction in health care costs in year 2 of follow-up. When considering change in health care costs over time, use of AOMs may be an effective strategy to mitigate the rising health care costs associated with obesity.

Effect of Bacteriocin-Like Inhibitory Substance (BLIS) from Enterococcus faecium DB1 on Cariogenic Streptococcus mutans Biofilm Formation.

The aim of the study was to investigate the effect of bacteriocin-like inhibitory substance (BLIS) from Enterococcus faecium DB1 on cariogenic Streptococcus mutans biofilm. Crystal violet staining, fluorescence, and scanning electron microscopy analyses demonstrated that the BLIS from Enterococcus faecium DB1 (DB1 BLIS) inhibited S. mutans biofilm. When DB1 BLIS was co-incubated with S. mutans, biofilm formation by S. mutans was significantly reduced (p<0.05). DB1 BLIS also destroyed the preformed biofilm of S. mutans. In addition, DB1 BLIS decreased the viability of S. mutans biofilm cells during the development of biofilm formation and in the preformed biofilm. DB1 BLIS significantly decreased the growth of S. mutans planktonic cells. Furthermore, S. mutans biofilm on the surface of saliva-coated hydroxyapatite discs was reduced by DB1 BLIS. Taken together, DB1 BLIS might be useful as a preventive and therapeutic agent against dental caries caused by S. mutans.
