- Bentonite clay is the soil that undergoes high volume changes (swelling) when its moisture content increases. The soil swelling may cause structural damage leading to damage to structural members like cracking in reinforced foundations and borders, curbs swelling, and eventually produces deformation indoors and on floors. In this study, Bentonite clay with expansive characteristics was used and mixed with various amounts of Pulverized waste glass PWG (0%, 5%, 10%, and 15%). Two types of PWG were prepared: fine glass (passing sieve No. 200) and coarse glass (passing sieve No. 2 mm). Laboratory experiments were performed on Bentonite specimens blended with different amounts of PWG. The results showed that the addition of 15% by Bentonite weight of 2 mm of PWG reduces the Atterberg limits considerably. Moreover, a noticeable reduction was observed in the Bentonite samples’ free swell and swelling pressure after being treated with different amounts of PWG. The observed advantages of adding the PWG to Bentonite clay soil by decreasing the volume changes and enhancing the overall properties of Bentonite clay reflect the suitability of using PGW as a good soil stabilizer. Besides reducing the impact of waste glass on the environment due to its non-biodegradable nature.

- Objectives Treatment-free remission (TFR) has emerged as a treatment goal in chronic myeloid leukemia in the chronic phase (CML-CP). Attempts to increase proportion of patients achieving TFR include combination of tyrosine kinase inhibitors (TKI) and other drugs. Interferon-alpha in addition to TKI has shown promising efficacy but with dose-dependent toxicity and discontinuations. NordCML007 was initiated to study the efficacy and safety of low dose pegylated IFN-alpha (PegIFN-alpha) in combination with dasatinib (DAS) in CML-CP. Methods Forty patients with newly diagnosed CML-CP were given DAS upfront. After month 3 (M3) 15 mu g/wk of PegIFN-alpha was added and increased to 25 mu g/wk from M7 until M15. DAS treatment was continued and adverse events and BCR-ABL1 qRT-PCR values were reported yearly after M24. Results from M1 to M18 have previously been published, and here we present long-term data. Results After 5 years of follow-up, there were no suspected unexpected serious adverse reactions, no increase in serosal effusions, no disease progressions and no CML-related deaths. Rates of MR3.0 (MMR), MR4.0 and MR4.5 were 84.6%, 64.1% and 51.3% respectively at M60, and 95% of patients reached MMR at some point during the study. Conclusion Initial addition of PegIFN-alpha to DAS shows good long-term efficacy without increased toxicity.

- Tyrosine kinase inhibitor (TKI) discontinuation in chronic myeloid leukemia (CML) has become part of routine care for patients with a sustained deep molecular response (DMR). Approximately 50% experience a molecular relapse upon TKI cessation. Most of them quickly regain DMR upon TKI resumption. Whether these patients can achieve a second treatment-free remission (TFR) remains unclear. DAstop2 (ClinicalTrials.gov ID: NCT03573596) is a prospective study including patients with a failed first TFR attempt re-treated with any TKI for ≥ one year. Upon entering the study, patients received the TKI dasatinib for additional two years. Patients with sustained DMR for ≥1 year qualified for a second TKI stop. Ninety-four patients were included between Oct 2017-Dec 2021. At the time of data analysis, 62 patients had attempted a 2nd stop. After a median follow-up of 27 months from 2nd stop, TFR rates were 61, 56 and 46% at 6, 12 and 24 months respectively. No progression to advanced stage disease was seen and 87% had re-achieved MR4 within a median of 3 months from TKI re-initiation. In summary, we show that a 2nd TFR attempt after dasatinib treatment is safe, feasible and TFR rates seem in the range of those reported in trials of a first TKI stop.

- We randomised 46 newly diagnosed patients with chronic myeloid leukaemia (median age 56) to receive dasatinib 100mg QD or imatinib 400mg QD and report outcome as an intention-to-treat analysis with 36months follow-up. Early cytogenetic and molecular responses were superior in the dasatinib group, with a tendency that imatinib patients caught up with time. For instance, MR3.0 was reached at 3months in 36% vs. 8% (P=0.02), at 12months in 81% vs. 46% (P=0.02) and at 18months in 73% vs. 65% (n.s.) of the patients in the two groups. In contrast, MR4.5 was consistently superior in the dasatinib group at all time points from 6months onwards, reaching 61% vs. 21% (P<0.05) at 36months. Sixty-four vs. 71% of the patients in the dasatinib and imatinib arms, respectively, remained on assigned drug. Dasatinib dose was frequently reduced, but with maintained excellent effect. One imatinib patient progressed to blastic phase, but no CML-related deaths occurred. In conclusion, our data compare favourably with those of the dasatinib registration study, DASISION. The fast and deep molecular responses induced by dasatinib compared with imatinib may be exploited to increase the proportion of patients who can achieve a treatment-free remission after treatment discontinuation.
