- The main objective of the MCL3 study was to improve outcome for patients not in CR before transplant by adding (90)Y-ibritumomab-tiuxetan (Zevalin) to the high-dose regimen. 160 consecutive, untreated stage II-IV MCL patients < 66 years received rituximab (R)- maxi-CHOP alternating with R-high-dose Ara-C (6 cycles total), followed by high-dose BEAM or BEAC and autologous stem cell transplantation 2005-2009. Zevalin (0.4 mCi/kg) was given to responders in only CRu/PR prior to high-dose therapy. The overall response rate (ORR) pre-transplant was 97%. After a median follow-up of 4.4 years the outcome did not differ from that of the historic control, the MCL2 trial with the same treatment except for Zevalin. Overall (OS), event free (EFS), and progression-free survival (PFS) at 4 years were 78, 62 and 71%, respectively. For patients in CRu/PR before transplant who received Zevalin duration of response was shorter than in the CR group. Inferior PFS, EFS- and OS were predicted by PET-positivity pre-transplant and detectable minimal residual disease (MRD) before and after transplant. In conclusion, a positive PET prior to transplant and MRD are strong predictors of outcome. Late intensification with Zevalin may be too late to improve the outcome of patients not in CR before transplant.

- The purpose of the present study was to investigate the association between smoking and the development of bladder cancer. The study population consisted of 429,906 persons participating in the European Prospective Investigation into Cancer and Nutrition (EPIC), 633 of whom developed bladder cancer during the follow-up period. An increased risk of bladder cancer was found for both current- (incidence rate ratio 3.96, 95% confidence interval: 3.07-5.09) and ex- (2.25, 1.74-2.91) smokers, compared to never-smokers. A positive association with intensity (per 5 cigarettes) was found among current-smokers (1.18, 1.09-1.28). Associations (per 5 years) were observed for duration (1.14, 1.08-1.21), later age at start (0.75, 0.66-0.85) and longer time since quitting (0.92, 0.86-0.98). Exposure to environmental tobacco smoke (ETS) during childhood increased the risk of bladder cancer (1.38, 1.00-1.90), whereas for ETS exposure as adult no effect was detected. The present study confirms the strong association between smoking and bladder cancer. The indication of a higher risk of bladder cancer for those who start smoking at a young age and for those exposed to ETS during childhood adds to the body of evidence suggesting that children are more sensitive to carcinogens than adults.

- Background Randomized trials of venetoclax plus anti-CD20 antibodies as first-line treatment in fit patients (i.e., those with a low burden of coexisting conditions) with advanced chronic lymphocytic leukemia (CLL) have been lacking. Methods In a phase 3, open-label trial, we randomly assigned, in a 1:1:1:1 ratio, fit patients with CLL who did not have TP53 aberrations to receive six cycles of chemoimmunotherapy (fludarabine-cyclophosphamide-rituximab or bendamustine-rituximab) or 12 cycles of venetoclax-rituximab, venetoclax-obinutuzumab, or venetoclax-obinutuzumab-ibrutinib. Ibrutinib was discontinued after two consecutive measurements of undetectable minimal residual disease or could be extended. The primary end points were undetectable minimal residual disease (sensitivity,

- Introduction: Recycling of domestic waste and a number of employees in the recycling industry is expected to increase. This study aims to quantify current exposure levels of inhalable dust, endotoxin, and microorganisms and to identify determinants of exposure among recycling workers. Methods: This cross-sectional study included 170 full-shift measurements from 88 production workers and 14 administrative workers from 12 recycling companies in Denmark. The companies recycle domestic waste (sorting, shredding, and extracting materials from waste). We collected inhalable dust with personal samplers that were analysed for endotoxin (n = 170) and microorganisms (n = 101). Exposure levels of inhalable dust, endotoxin, and microorganisms and potential determinants of exposure were explored by mixed-effects models. Results: The production workers were 7-fold or higher exposed to inhalable dust, endotoxin, bacteria, and fungi than the administrative workers. Among production workers recycling domestic waste, the geometric mean exposure level was 0.6 mg/m3 for inhalable dust, 10.7 endotoxin unit (EU)/m3 for endotoxin, 1.6 × 104 colony forming units (CFU)/m³ of bacteria, 4.4 × 104 CFU/m³ of fungi (25 °C), and 1.0 × 103 CFU/m³ of fungi (37 °C). Workers handling paper or cardboard had higher exposure levels than workers handling other waste fractions. The temperature did not affect exposure levels, although there was a tendency toward increased exposure to bacteria and fungi with higher temperatures. For inhalable dust and endotoxin, exposure levels during outdoor work were low compared to indoor work. For bacteria and fungi, indoor ventilation decreased exposure. The work task, waste fraction, temperature, location, mechanical ventilation, and the company size explained around half of the variance of levels of inhalable dust, endotoxin, bacteria, and fungi. Conclusion: The production workers of the Danish recycling industry participating in this study had higher exposure levels of inhalable dust, endotoxin, bacteria, and fungi than the administrative workers. Exposure levels of inhalable dust and endotoxin among recycling workers in Denmark were generally below established or suggested occupational exposure limits (OEL). However, 43% to 58% of the individual measurements of bacteria and fungi were above the suggested OEL. The waste fraction was the most influential determinant for exposure, and the highest exposure levels were seen during handling paper or cardboard. Future studies should examine the relationship between exposure levels and health effects among workers recycling domestic waste.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The human papillomavirus (HPV) is a risk factor for a subgroup of head and neck cancers (HNC). HPV-positive and HPV-negative HNC patients encompass heterogeneous groups regarding risk factors, sociodemographic and clinical characteristics, which may influence health-related quality of life (HRQL) differently. Since this has been sparsely studied, our study investigated the association between HPV status and HRQL in HNC survivors in Denmark. Materials and methods: This cross-sectional study included 179 recurrence-free oropharyngeal and oral cavity squamous cell carcinoma (OSCC) survivors. HRQL was assessed on the EORTC QLQ-C30 and QLQ-H&N35 questionnaires. Linear and logistic regression models were adjusted for sociodemographic, clinical and lifestyle factors. Results: Most unadjusted results showed better HRQL among HPV-positive (n = 119) compared to HPV-negative (n = 60) OSCC survivors (average 18 months since diagnosis). After adjustments, the HPV-positive survivors reported higher role functioning (mean difference [MD] 9.2, 95% confidence interval [CI] 0.1 to –18.4), and fewer problems with speech (MD −9.0, 95% CI −18.0 to −0.1), sexuality (MD −21.9, 95% CI −38.0 to −5.9) and opening mouth (MD −13.7, 95% CI −26.6 to −0.8) compared to HPV-negative survivors. Conclusion: Our findings support that HPV-positive OSCC survivors experience better HRQL than HPV-negative survivors. However, results indicate that sociodemographic, clinical and lifestyle factors explain most of the association between HPV status and HRQL. Findings suggest increased focus on the HPV-negative OSCC survivors with deteriorated HRQL in rehabilitation programs and future research to investigate the long-term effects of treatment among HPV-positive OSCC survivors who may develop symptoms later in survivorship.

- Gold nanoparticles (Au NPs) and gold-based nanomaterials combine unique properties relevant for medicine, imaging, optics, sensing, catalysis, and energy conversion. While the Turkevich-Frens and Brust-Schiffrin methods remain the state-of-the-art colloidal syntheses of Au NPs, there is a need for more sustainable and tractable synthetic strategies leading to new model systems. In particular, stabilizers are almost systematically used in colloidal syntheses, but they can be detrimental for fundamental and applied studies. Here, a surfactant-free synthesis of size-controlled colloidal Au NPs stable for months is achieved by the simple reduction of HAuCl4 at room temperature in alkaline solutions of low-viscosity mono-alcohols such as ethanol or methanol and water, without the need for any other additives. Palladium (Pd) and bimetallic AuxPdy NPs, nanocomposites and multimetallic samples, are also obtained and are readily active (electro)catalysts. The multiple benefits over the state-of-the-art syntheses that this simple synthesis bears for fundamental and applied research are highlighted.

Different or the same? exploring the physicochemical properties and molecular mobility of celecoxib amorphous forms
- 2024

Ingår i: International Journal of Pharmaceutics. - 0378-5173. ; 661

Tidskriftsartikel (refereegranskat)abstract
- The influence of different preparation methods on the physicochemical properties of amorphous solid forms have gained considerable attention, especially with recent publications on pharmaceutical polyamorphism. In the present study, we have investigated the possible occurrence of polyamorphism in the drug celecoxib (CEL) by investigating the thermal behavior, morphology, structure, molecular mobility and physical stability of amorphous CEL obtained by quench-cooling (QC), ball milling (BM) and spray drying (SD). Similar glass transition temperatures but different recrystallization behaviors were observed for CEL-QC, CEL-BM and CEL-SD using modulated differential scanning calorimetry analysis. A correlation between the different recrystallization behaviors of the three CEL amorphous forms and the respective distinct powder morphologies, was also found. Molecular dynamics simulations however, reveal that CEL presents similar molecular conformational distributions when subjected to QC and SD. Moreover, the obtained molecular conformational distributions of CEL are different from the ones found in its crystal structure and also from the ones found in the lowest-energy structure obtained by quantum mechanical calculations. The type and strength of CEL hydrogen bond interactions found in CEL-QC and CEL-SD systems are almost identical, though different from the ones presented in the crystal structure. Pair distribution function analyses and isothermal microcalorimetry show similar local structures and structural relaxation times, respectively, for CEL-QC, CEL-BM and CEL-SD. The present work shows that not only similar physicochemical properties (glass transition temperature, and structural relaxation time), but also similar molecular conformational distributions were observed for all prepared CEL amorphous systems. Hence, despite their different recrystallization behaviors, the three amorphous forms of CEL did not show any signs of polyamorphism.

- Purpose: Multidisciplinary team (MDT) meetings integrate complex information and base recommendations for clinical management on interdisciplinary and multiprofessional deci-sion-making. To support high-quality decision-making and define key performance indica-tors, we aimed to determine completeness of case information and contributions to MDT case discussions in cancer care. Methods: In a prospective observational study design, based on three MDTs, we applied the Metric for Observation of Decision-Making (MODe) tool to assess the quality of case presentation and team members’ contributions to case discussions. The MDTs handled patients with brain tumors, soft tissue sarcomas and hepatobiliary cancers. The results were correlated to patient and team characteristics and to MDT leadership skills. Results: Data were collected from 349 case discussions during 32 MDT meetings. Information on radiology received the highest scores, followed by case history and information on histopathology. Patient-related information was less frequently mentioned and gen-erally received low scores. Contributions to the case discussions were predominantly by the chair, surgeons, and oncologists with limited contributions from nurses. Leadership skills showed a positive correlation with case presentations scores and failure to reach a treatment recommendation correlated with lower case discussion scores. Conclusion: Considerable resources are spent on MDT meetings in cancer care, which motivate initiatives to ensure high-quality and efficient decision-making processes. We identify unbalanced contributions from team members during MDT meetings, demonstrate limited provision of patient-related information and show that leadership skills may posi-tively influence the quality of the case presentations. We suggest that MDTs should consider and develop these aspects to ensure high-quality MDT-based case management and decision-making.
