RESUMO
BACKGROUND: Several SGLT2i (sodium-glucose transport protein 2 inhibitors) and GLP1-RA (glucagon-like peptide-1 receptor agonists) reduce cardiovascular events and improve kidney outcomes in patients with type 2 diabetes; however, utilization remains low despite guideline recommendations. METHODS: A randomized, remote implementation trial in the Mass General Brigham network enrolled patients with type 2 diabetes with increased cardiovascular or kidney risk. Patients eligible for, but not prescribed, SGLT2i or GLP1-RA were randomly assigned to simultaneous virtual patient education with concurrent prescription of SGLT2i or GLP1-RA (ie, Simultaneous) or 2 months of virtual education followed by medication prescription (ie, Education-First) delivered by a multidisciplinary team driven by nonlicensed navigators and clinical pharmacists who prescribed SGLT2i or GLP1-RA using a standardized treatment algorithm. The primary outcome was the proportion of patients with prescriptions for either SGLT2i or GLP1-RA by 6 months. RESULTS: Between March 2021 and December 2022, 200 patients were randomized. The mean age was 66.5 years; 36.5% were female, and 22.0% were non-White. Overall, 30.0% had cardiovascular disease, 5.0% had cerebrovascular disease, and 1.5% had both. Mean estimated glomerular filtration rate was 77.9 mL/(minâ§1.73 m2), and mean urine/albumin creatinine ratio was 88.6 mg/g. After 2 months, 69 of 200 (34.5%) patients received a new prescription for either SGLT2i or GLP1-RA: 53.4% of patients in the Simultaneous arm and 8.3% of patients in the Education-First arm (P<0.001). After 6 months, 128 of 200 (64.0%) received a new prescription: 69.8% of patients in the Simultaneous arm and 56.0% of patients in Education-First (P<0.001). Patient self-report of taking SGLT2i or GLP1-RA within 6 months of trial entry was similarly greater in the Simultaneous versus Education-First arm (69 of 116 [59.5%] versus 37 of 84 [44.0%]; P<0.001) Median time to first prescription was 24 (interquartile range [IQR], 13-50) versus 85 days (IQR, 65-106), respectively (P<0.001). CONCLUSIONS: In this randomized trial, a remote, team-based program identifies patients with type 2 diabetes and high cardiovascular or kidney risk, provides virtual education, prescribes SGLT2i or GLP1-RA, and improves guideline-directed medical therapy. These findings support greater utilization of virtual team-based approaches to optimize chronic disease management. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT06046560.

Diabetes is a major risk factor for tendinopathy, and tendon abnormalities are common in diabetic patients. The purpose of the present study was to evaluate the effect of streptozotocin (60 mg/kg)-induced diabetes and insulin therapy on tendon mechanical and cellular properties. Sprague-Dawley rats (n = 40) were divided into the following four groups: nondiabetic (control), 1 wk of diabetes (acute), 10 wk of diabetes (chronic), and 10 wk of diabetes with insulin treatment (insulin). After 10 wk, Achilles tendon and tail fascicle mechanical properties were similar between groups (P > 0.05). Cell density in the Achilles tendon was greater in the chronic group compared with the control and acute groups (control group: 7.8 ± 0.5 cells/100 µm(2), acute group: 8.3 ± 0.4 cells/100 µm(2), chronic group: 10.9 ± 0.9 cells/100 µm(2), and insulin group: 9.2 ± 0.8 cells/100 µm(2), P < 0.05). The density of proliferating cells in the Achilles tendon was greater in the chronic group compared with all other groups (control group: 0.025 ± 0.009 cells/100 µm(2), acute group: 0.019 ± 0.005 cells/100 µm(2), chronic group: 0.067 ± 0.015, and insulin group: 0.004 ± 0.004 cells/100 µm(2), P < 0.05). Patellar tendon collagen content was â¼32% greater in the chronic and acute groups compared with the control or insulin groups (control group: 681 ± 63 µg collagen/mg dry wt, acute group: 938 ± 21 µg collagen/mg dry wt, chronic: 951 ± 52 µg collagen/mg dry wt, and insulin group: 596 ± 84 µg collagen/mg dry wt, P < 0.05). In contrast, patellar tendon hydroxylysyl pyridinoline cross linking and collagen fibril organization were unchanged by diabetes or insulin (P > 0.05). Our findings suggest that 10 wk of streptozotocin-induced diabetes does not alter rat tendon mechanical properties even with an increase in collagen content. Future studies could attempt to further address the mechanisms contributing to the increase in tendon problems noted in diabetic patients, especially since our data suggest that hyperglycemia per se does not alter tendon mechanical properties.

INTRODUCTION: Once-weekly subcutaneous semaglutide, a glucagon-like peptide-1 analog, is approved in the USA as an adjunct to diet and exercise for adults with inadequately controlled type 2 diabetes (T2D) to improve glycemic control and reduce the risk of major adverse cardiovascular events in people with T2D and established cardiovascular disease. The Semaglutide Unabated Sustainability in Treatment of Type 2 Diabetes (SUSTAIN) phase III clinical trial program demonstrated the efficacy and safety of once-weekly subcutaneous semaglutide; however, determining its effectiveness in a real-world setting could support decision-making by clinicians, payers and policy makers in routine clinical practice. RESEARCH DESIGN AND METHODS: SEmaglutide PRAgmatic (SEPRA) is an ongoing open-label, randomized, pragmatic clinical trial designed to compare the effects of once-weekly subcutaneous semaglutide versus standard of care in US health-insured adults with T2D and physician-determined inadequate glycemic control. The primary end point is the proportion of participants achieving glycated hemoglobin (HbA1c) <7.0% at year 1; other key outcomes include glycemic control, weight loss, healthcare utilization, and patient-reported outcomes. Individual-level data will be collected from routine clinical practice and health insurance claims. The last patient last visit is expected by June 2023. RESULTS: Between July 2018 and March 2021, 1278 participants were enrolled from 138 study sites across the USA. At baseline, 54% were male with mean±SD age 57.4±11.1 years and body mass index 35.7±8.0 kg/m2. Mean diabetes duration was 7.4±6.0 years and mean HbA1c was 8.5±1.6%. At baseline, concomitant antidiabetes medications included metformin, sulfonylureas, sodium-glucose co-transporter-2 inhibitors, and dipeptidyl peptidase-4 inhibitors. The majority of participants had hypertension and dyslipidemia. The trial design was self-assessed using the PRagmatic Explanatory Continuum Indicator Summary-2 tool by the study steering group and was scored 4-5 in all domains suggesting a highly pragmatic study. CONCLUSIONS: SEPRA, a highly pragmatic ongoing study, will provide data on the effects of once-weekly subcutaneous semaglutide in a real-world setting when used during routine management of T2D. TRIAL REGISTRATION NUMBER: NCT03596450.

BACKGROUND: Primary immune-deficiency disease (PIDD) is a rare, debilitating disease of the immune system that predisposes the affected individual to infection, autoimmune conditions, and neoplasm. A major component of the cost of treating PIDD is the high price of immunoglobulin drugs, which can be administered via an intravenous (IV) or subcutaneous (SC) route. OBJECTIVE: To compare real-world costs for patients with PIDD who are receiving IV immunoglobulin (IVIG) or SC immunoglobulin (SCIG) treatment, from a US payer perspective, using a large claims database. METHODS: Based on 2011 to 2013 data from the PharMetrics Plus database, a large national healthcare claims database, patients who were newly diagnosed with PIDD were included in the study if they had ≥2 claims for PIDD that were ≥90 days apart, and if they were treatment-naïve for a minimum of 1 year before the study period. Patients who switched the route of immunoglobulin administration were excluded, with the exception of patients who received SCIG who could initially receive ≤2 IV-loading infusions, as directed by treatment guidelines. We used propensity score analysis to match the patients in the SCIG cohort to patients in the IVIG cohort based on age, sex, and all Elixhauser comorbidities. We compared the patient characteristics and direct medical costs (all-cause, PIDD-related, and pharmacy-related) before and after matching, using t-tests for continuous variables, chi-square test for categorical variables, and Wilcoxon rank-sum test for differences in medians. RESULTS: A total of 1639 patients with PIDD (986 who received IVIG and 653 who received SCIG) met all the study inclusion criteria. Compared with the patients who received IVIG, the patients who received SCIG were predominantly female (58% vs 63%, respectively) and significantly younger (mean age, 49.1 vs 40.3 years, respectively). Significantly fewer patients who received SCIG than those receiving IVIG had claims with International Classification of Diseases, Ninth Revision codes for Elixhauser comorbidities, including cardiovascular and pulmonary conditions, diabetes, renal failure, liver disease, cancers, weight loss, fluid and electrolyte disorders, and psychoses (P <.05 for all), and their Charlson Comorbidity Index scores were lower than those receiving IVIG (1.74 vs 3.01, respectively; P ≤.05 for all). After matching the 2 cohorts (N = 553 in each), the 1-year postindex median total PIDD-related costs were significantly lower in the IVIG group than in the SCIG group ($38,064 vs $43,266, respectively; P = .002). CONCLUSIONS: In matched analyses, PIDD-related treatment costs were higher for patients who received SCIG than for those who received IVIG. Furthermore, patients who received SCIG were significantly younger and had significantly less comorbidities than their counterparts who received IVIG, suggesting that patient characteristics that reflect a desire and greater capacity for autonomy may affect physicians' choice of the route of administration for immunoglobulin.
RESUMO
Purpose: For chronic inflammatory demyelinating polyneuropathy (CIDP) patients, each branded intravenous immunoglobulin (IVIG) treatment differs in production processes, virus elimination, formulation, and composition. Given the limited availability of real-world data comparing IVIGs for CIDP, this study evaluated switching patterns between IVIG products in 2 separate retrospective databases. Patients and methods: Two independent analytic teams retrospectively evaluated IVIG treatment-naïve patients with an ICD diagnosis code for CIDP. Study 1 used integrated healthcare claims from IMS LifeLink PharMetrics Plus™ and Study 2 used the Truven MarketScan® Database. All analyses were descriptive, with outcomes assessed during the 2-year post-index period. Results: One-quarter of IVIG patients switched therapies within the 2-year study period. In both studies, switching rates were lowest for IVIG-G (Gamunex®-C) (Study 1: 9.8%, Study 2: 8.9%), followed by IVIG-F (Flebogamma®) (Study 1: 25.0%, Study 2: 18.2%), and highest for IVIG-other (Octagam®/Gammaplex®) (Study 1: 50.0%, Study 2: 33.3%). When patients were switched, most switched to IVIG-G (Study 1: 51.6%, Study 2: 54.3%). Conclusion: The small proportion of CIDP switchers in 2 independent studies suggests that IVIG therapy is generally well tolerated. However, differences existed in switch rates for different IVIG products. The reason for low switching rates could not be assessed in this study; therefore, further studies are required to detect possible relevant differences in effectiveness and tolerability.
RESUMO
PURPOSE: Isometric handgrip (IHG) training lowers systolic and diastolic blood pressure (SBP and DBP, respectively), but the efficacy of IHG training in cardiopulmonary rehabilitation patients is unknown. The purpose of this study was to determine if IHG decreases blood pressure in cardiopulmonary rehabilitation patients. METHODS: Cardiopulmonary rehabilitation program participants (n = 11; 50-80 yr old) were randomized to IHG (n = 6) or control (CON; no treatment; n = 5) groups. IHG participants completed an IHG training program at 30% maximal voluntary contraction, 3 d/wk for 6 wk. Resting SBP, DBP, and heart rate were assessed weekly. RESULTS: Mean regression for SBP following IHG was negative (-1.04 ± 0.80). Mean regression in the CON group was positive (0.50 ± 0.88), but there was no significant difference between groups. Separate analysis of weeks 1 to 7 yielded a negative mean regression (-1.12 ± 0.54) in the IHG group, but positive (1.2 ± 0.60) in the CON group. A Wilcoxon test of these differences yielded significance for SBP (P = .009). In 3 of 6 IHG participants, SBP was lower (mean ± SD: -16 ± 11 mm Hg; P = .12), and in 2 IHG participants, DBP was lower (-9 ± 1 mm Hg; P = .06) compared with baseline. In 2 of 5 CON participants, SBP was not significantly lower (-11 ± 7 mm Hg) and, in 3 of 5 CON participants, DBP was lower (-7 ± 4 mm Hg; P = .04). CONCLUSIONS: Our data suggest that standard IHG training may be inadequate for blood pressure management immediately following a major cardiac or pulmonary event. Future work with a larger cohort and more developed training protocol to determine the efficacy of IHG training in patients with cardiopulmonary disease is warranted.

Non-cystic fibrosis bronchiectasis (NCFBE) is a rare, chronic lung disease characterized by bronchial inflammation and permanent airway dilation. Chronic infections with P. aeruginosa have been linked to higher morbidity and mortality. To understand the impact of P. aeruginosa in NCFBE on health care costs and burden, we assessed healthcare costs and utilization before and after P. aeruginosa diagnosis. Using data from 2007 to 2013 PharMetrics Plus administrative claims, we included patients with ≥2 claims for bronchiectasis and >1 claim for P. aeruginosa; then excluded those with a claim for cystic fibrosis. Patients were indexed at first claim for P. aeruginosa and were required to have >12 months before and after the index P. aeruginosa. The mean differences in utilization and costs were assessed using paired Student's t-tests for statistical significance. Mean total healthcare costs per patient were $36,213 pre-P. aeruginosa diagnosis versus $67,764 post-P. aeruginosa, an increase of 87% (p < 0.0001). Inpatient costs represented the largest proportion of total healthcare costs post-P. aeruginosa (54%) with an increase of four hospitalizations per patient (p < 0.0001). NCFBE patients with evidence of P. aeruginosa incur substantially greater healthcare costs and utilization after P. aeruginosa diagnosis. Future research should explore methods of earlier identification of NCFBE patients with P. aeruginosa, as this may lead to fewer severe exacerbations, thereby resulting in a reduction in hospitalizations and healthcare costs.
RESUMO
Objectives: Little is known about severe chronic obstructive pulmonary disease (COPD) exacerbations among patients with Alpha-1 Antitrypsin Deficiency (AATD). We assessed inpatients with AATD and COPD among a sample of COPD inpatients to ascertain demographic, clinical and economic differences in the course of disease and treatment. Methods: Using data from the 2009 Nationwide Inpatient Sample (NIS), we identified COPD (ICD-9-CM: 491.xx, 492.xx, or 496.xx) patients with AATD (273.4). We compared patient demographics and healthcare outcomes (eg, length of stay, inpatient death, type and number of procedures, and cost of care) between COPD patients with and without alpha-1 antitrypsin deficiency. Frequencies and percentages for patient demographics were compared using bivariate statistics (eg, chi-square test). Recognizing the non-parametric nature of length of stay and cost, we calculated median values and interquartile ranges for these variables for each group of patients. Finally, the risk of inpatient death was estimated using logistic regression. Results: Of 840 242 patients with COPD (10.8% of the NIS sample population), 0.08% (684) had a primary or secondary diagnosis code for AATD. COPD+AATD were younger (56 vs 70, p<0.0001) and as a result, less likely to be covered by Medicare (44% vs 62%, p<0.0001). AATD patients were also more likely to have comorbid non-alcoholic liver disease (7% vs 2%, p<0.0001), depression (17% vs 13%, p=0.0328), and pulmonary circulation disorders (7% vs 4%, p=0.0299). Patients with AATD had a 14% longer length of stay (IRR = 1.14, 95% CI 1.07, 1.21) and a mean cost of $1487 (p=0.0251) more than COPD inpatients without AATD. Conclusions: AATD is associated with increased mean length of stay and cost, as well as higher frequency of comorbid non-alcoholic liver disease, depression, and pulmonary circulation disorders. Future research should assess other differences between AATD and the general COPD population such as natural history of disease, treatment responsiveness and disease progression.
RESUMO
BACKGROUND: Although a number of monoimmunotherapies and targeted therapies are available to treat BRAF+ advanced melanoma, response rates remain relatively low in the range of 22-53% with progression-free survival (PFS) in the range of 4.8-8.8 months. Recently, combination targeted therapies have improved response rates to about 66-69%, PFS to 11.0-12.6 months and overall survival (OS) to 25.1-25.6 months. While combination immunotherapies have improved response rates of 67 compared with 19-29% with monotherapies and improved PFS of 11.7 compared with 4.4-5.8 months with monotherapies, the OS benefit is yet to be established in phase 3 trials. As healthcare costs continue to rise, US payers have a predominant interest in assessing the value of available treatments. Therefore, a cost-benefit model was developed to evaluate the value of treating BRAF+ advanced melanoma with two combination therapies: nivolumab + ipilimumab (N+I) and dabrafenib + trametinib (D+T). SCOPE: The model was used to estimate total costs, total costs by expenditure category, cost per month of PFS and cost per responder for the payer, and societal perspectives of treating advanced melanoma patients with the BRAF V600 mutation using combination targeted therapy (D+T) or combination immunotherapy (N+I). The model followed patients from initiation of treatment to the point of progression or death. Deterministic and probabilistic sensitivity analyses were conducted to evaluate the robustness of the results and to understand the dispersion of simulated results. FINDINGS: Based on a hypothetical payer with one million covered lives, it was expected that fourteen metastatic melanoma patients with the BRAF V600 mutation would be treated each year. Cost-benefit with N+I and D+T was simulated from the payer perspective. The cost per month of PFS for N+I was $22,162, while that for D+T was $17,716 (-$4,446 cost difference); the cost per responder for N+I was $388,746 and that for D+T was $282,429 (-$106,316 cost difference). The cost per month of PFS and per responder from the societal perspective resembled the patterns observed from the payer's perspective: the cost per month of PFS for N+I was $22,843, while that for D+T was $18,283 (-$4,560 cost difference). The cost per responder for N+I was $400,695 and that for D+T was $291,473 (-$109,222 cost difference). The totals of travel and treatment time for N+I and D+T were 58 hours and 3.9 hours per patient, respectively, of which total infusion time for N+I accounted for a majority - 59% - of the 58 hours. Sensitivity analyses indicated that results were most sensitive to model inputs for median PFS, body weight, and drug cost. Moreover, D+T is likely associated with a lower cost per month of PFS and cost per responder than N+I, except at low body weights (less than 57 kg). CONCLUSION: The model presented in this study was used to analyze the clinical and economic benefit of using combination therapies in advanced melanoma patients with the BRAF V600 mutation. This analysis suggests D+T therapy is associated with less patient time and lower costs relative to N+I to gain similar PFS and overall response rate (ORR) benefits.
RESUMO
BACKGROUND: Cancer cachexia is a debilitating condition and results in poor prognosis. The purpose of this study was to assess hospitalization incidence, patient characteristics, and medical cost and burden of cancer cachexia in the US. METHODS: This study used a cross-sectional analysis of the Nationwide Inpatient Sample (NIS) for 2009. Five cancers reported to have the highest cachexia incidence were assessed. The hospitalization incidence related to cachexia was estimated by cancer type, cost and length of stay were compared, and descriptive statistics were reported for each cancer type, as well as differences being compared between patients with and without cachexia. RESULTS: Risk of inpatient death was higher for patients with cachexia in lung cancer (OR = 1.32; CI = 1.20-1.46) and in all cancers combined (OR = 1.76; CI = 1.67-1.85). The presence of cachexia increased length of stay in lung (IRR = 1.05; CI = 1.03-1.08), Kaposi's sarcoma (IRR = 1.47; CI = 1.14-1.89) and all cancers combined (IRR = 1.09; CI = 1.08-1.10). Additionally, cachectic patients in the composite category had a longer hospitalization stay compared to non-cachectic patients (3-9 days for those with cachexia and 2-7 days for those without cachexia). The cost of inpatient stay was significantly higher in cachexic than non-cachexic lung cancer patients ($13,560 vs $13 190; p < 0.0001), as well as cachexic vs non-cachexic cancer patients in general (14 751 vs 13 928; p < 0.0001). CONCLUSIONS: Cachexia increases hospitalization costs and length of stay in several cancer types. Identifying the medical burden associated with cancer cachexia will assist in developing an international consensus for recognition and coding by the medical community and ultimately an effective treatment plans for cancer cachexia.
