Comparisons of School-Day Glycemia in Different Settings for Children with Type 1 Diabetes Using Continuous Glucose Monitoring

Objective. Using continuous glucose monitoring (CGM), we examined patterns in glycemia during school hours for children with type 1 diabetes, exploring diferences between school and nonschool time. Methods. We conducted a retrospective analysis of CGM metrics in children 7-12 years (n = 217, diabetes duration 3.5 +/- 2.5 years, hemoglobin A1c 7.5 +/- 0.8%). Metrics were obtained for weekday school hours (8 AM to 3 PM) during four weeks in fall 2019. Two comparison settings included weekend (fall 2019) and weekday (spring 2020) data when children had transitioned to virtual school due to COVID-19. We used multilevel mixed models to examine factors associated with time in range (TIR) and compare glycemia between in-school, weekends, and virtual school. Results. Tough CGM metrics were clinically similar across settings, TIR was statistically higher, and time above range (TAR), mean glucose, and standard deviation (SD) were lower, for weekends and virtual school (p < 0.001). Hour and setting exhibited a signifcant interaction for several metrics (p < 0.001). TIR in-school improved from a mean of 40.9% at the start of the school day to 58.0% later in school, with a corresponding decrease in TAR. TIR decreased on weekends (60.8 to 50.7%) and virtual school (62.2 to 47.8%) during the same interval. Mean glucose exhibited a similar pattern, though there was little change in SD. Younger age (p = 0.006), lower hemoglobin A1c (p < 0.001), and insulin pump use (p = 0.02) were associated with higher TIR in-school. Conclusion. Although TIR was higher for weekends and virtual school, glycemic metrics improve while in-school, possibly related to benefcial school day routines.

Efficacy and Safety of Front-Line Venetoclax and Rituximab (VenR) for the Treatment of Young Patients with Chronic Lymphocytic Leukemia and an Unfavorable Biologic Profile. Preliminary Results of the Gimema Study ‘Veritas‘

Fixed-duration treatment with venetoclax (Ven), a highly selective Bcl-2 inhibitor combined with an anti-CD20 monoclonal antibody, showed high efficacy inducing high rates of deep responses with undetectable minimal residual disease (uMRD) in patients with previously treated and untreated chronic lymphocytic leukemia (CLL). The efficacy and safety of the Ven and rituximab (VenR) combination have been investigated in a multicenter, prospective study of the GIMEMA group that included young patients with previously untreated CLL (LLC 1518, VERITAS, NCT03455517). The primary endpoint of this study was the CR rate assessed according to the iwCLL criteria. Inclusion criteria were: treatment requirement per iwCLL criteria, age ≤65 years, cumulative Illness rating scale score ≤6, creatinine clearance ≥30 mL/min, and an unfavorable biologic profile with IGHV unmutated and or TP53 disruption. Treatment consisted of the Ven dose ramp-up (from 20 to 400 mg daily, during 5-weeks) followed by Ven 400 mg daily, combined with R for six 28-day courses (375 mg/m2, course 1;500 mg/m2, courses 2-6). Patients continued with Ven single agent, 400 mg daily, until month 13. Tumor lysis syndrome (TLS) prophylaxis measures included hydration, allopurinol, or rasburicase. All patients received Pneumocystis Jirovecii prophylaxis. G-CSF was given in patients with recurrent and severe granulocytopenia. Adverse events (AEs) were graded according to the CTCAE criteria v.5, TLS events were classified according to Howard's criteria. Response was assessed at months 7 and 15 and included clinical examination, PB evaluation, BM aspirate, BM biopsy, and CT scan. MRD was checked centrally in the PB and BM by a 6/4-color flow-cytometry assay with a sensitivity of at least 10-4 according to the internationally standardized European Research Initiative on CLL. Quantitative MRD results assessed by flow-cytometry were categorized as uMRD (uMRD4;<10-4), intermediate MRD, or high MRD (≥10-2). MRD was further evaluated by allele-specific oligonucleotide PCR with a sensitivity up to 10-5 in the PB and BM of patients who showed uMRD4 by flow-cytometry. During the follow-up, MRD was monitored every 6 months. Between October 2018 and May 2020, 77 patients with CLL were included in this study. Two patients were off study before the start of treatment (withdrawal of consent, 1;Covid-19 infection, 1) and were not included in the analysis. The median age was 53.5 years (range 38-65). Binet stage B/C was present in 84% of patients, increased beta-2 microglobulin in 41%. Seventy-one (96%) of patients were IGHV unmutated, while 3 (4%) were IGHV mutated and showed TP53 mutation (Table 1). At the data cutoff of June 30, 2020, 65 (87%) patients completed the ramp-up phase. The planned 400 mg dose of Ven was reached within 5 weeks in 78.5% of patients. Response was assessed in 34 patients at the end of the VenR combination therapy. A response was achieved by 32 (94%) patients. Responses included 20 (59%) CRs, 1 CRi (3%) and 11 (32%) PRs due to residual enlarged nodes (median maximum size, 1.9 cm). Treatment failure due to toxicity was recorded in 2 (6%) patients. Overall, a response with uMRD4 by flow-cytometry in the PB was observed in 26 (76.5%) cases, and in the PB and BM, in 17 (50.0%). The rates of patients with CR and uMRD4 by flow-cytometry in the PB, and both in the PB and BM, were 44%, and 35%, respectively (Table 2). No detectable disease by PCR, both in the PB and BM, was observed in 4 (12%) patients. With a median follow-up of 4.5 months from the start of therapy, no patient has progressed or died. Fifty-three percent of patients were hospitalized during the first seven days of the Ven ramp-up phase. A transient laboratory TLS was observed in 3 patients. Treatment was discontinued after the first dose of Ven in 1 patient with evidence of laboratory TLS associated with severe neurologic toxicity due to the concomitant administration of fentanyl. Selected grade ≥3 AEs included neutropenia in 10 patients (ramp-up phase, 5) and neutropenic fever in 4. Gra e ≥3 infection was recorded in 3 patients and was the reason for treatment discontinuation in 1 who developed COVID-19 pneumonia. In conclusion, the preliminary results of this study demonstrate the high efficacy of the front-line VenR combination, which resulted in a high proportion of CRs and responses with uMRD4 in young patients with CLL and an unfavorable biologic profile.

Give more data, awareness and control to individual citizens, and they will help COVID-19 containment

The rapid dynamics of COVID-19 calls for quick and effective tracking of virus transmission chains and early detection of outbreaks, especially in the “phase 2” of the pandemic, when lockdown and other restriction measures are progressively withdrawn, in order to avoid or minimize contagion resurgence. For this purpose, contact-tracing apps are being proposed for large scale adoption by many countries. A centralized approach, where data sensed by the app are all sent to a nation-wide server, raises concerns about citizens’ privacy and needlessly strong digital surveillance, thus alerting us to the need to minimize personal data collection and avoiding location tracking. We advocate the conceptual advantage of a decentralized approach, where both contact and location data are collected exclusively in individual citizens’ “personal data stores”, to be shared separately and selectively (e.g., with a backend system, but possibly also with other citizens), voluntarily, only when the citizen has tested positive for COVID-19, and with a privacy preserving level of granularity. This approach better protects the personal sphere of citizens and affords multiple benefits: It allows for detailed information gathering for infected people in a privacy-preserving fashion;and, in turn this enables both contact tracing, and, the early detection of outbreak hotspots on more finely-granulated geographic scale. The decentralized approach is also scalable to large populations, in that only the data of positive patients need be handled at a central level. Our recommendation is two-fold. First to extend existing decentralized architectures with a light touch, in order to manage the collection of location data locally on the device, and allowthe user to share spatio-temporal aggregates-if and when they want and for specific aims-with health authorities, for instance. Second, we favour a longerterm pursuit of realizing a Personal Data Store vision, giving users the opportunity to contribute to collective good in the measure they want, enhancing self-awareness, and cultivating collective efforts for rebuilding society. © 2020, University of Skovde.
