- AIMS: This study assessed radiotherapy combined with capecitabine and oxaliplatin in patients with primary, inextirpable colorectal adenocarcinoma. PATIENTS AND METHODS: Forty-nine patients entered the trial. Two cycles of XELOX (capecitabine 1000mg/m(2) bid d1-14+oxaliplatin 130mg/m(2) d1, q3w) were followed by radiotherapy (50.4Gy), combined with capecitabine 825mg/m(2) bid every radiotherapy day and oxaliplatin 60mg/m(2) once weekly. The primary end-point was objective response. RESULTS: Forty-seven patients were evaluable. Twenty-nine (62% [95% CI: 46-75%]) achieved complete or partial response. Thirty-eight (81%) went through surgery of whom 37 (97%) had an R0 resection and five (13%) had a pathological complete response. Seventy-eight percent were alive and estimated local progression rate was 11% at 2 years. The most common grade 3+ toxicity during chemoradiotherapy was diarrhoea (24%). CONCLUSIONS: XELOX-RT was feasible and showed promising efficacy when treating patients with primary inextirpable colorectal cancer, establishing high local control rate.

- Antimicrobial resistance (AMR) is a major threat to global health. Understanding the emergence, evolution, and transmission of individual antibiotic resistance genes (ARGs) is essential to develop sustainable strategies combatting this threat. Here, we use metagenomic sequencing to analyse ARGs in 757 sewage samples from 243 cities in 101 countries, collected from 2016 to 2019. We find regional patterns in resistomes, and these differ between subsets corresponding to drug classes and are partly driven by taxonomic variation. The genetic environments of 49 common ARGs are highly diverse, with most common ARGs carried by multiple distinct genomic contexts globally and sometimes on plasmids. Analysis of flanking sequence revealed ARG-specific patterns of dispersal limitation and global transmission. Our data furthermore suggest certain geographies are more prone to transmission events and should receive additional attention.

- The effects of extracts from five cultivars of strawberries on the proliferation of colon cancer cells HT29 and breast cancer cells MCF-7 were investigated, and possible correlations with the levels of several antioxidants were analyzed. In addition, the effects of organic cultivation compared to conventional cultivation on the content of antioxidants in the strawberries and strawberry extracts on the cancer cell proliferation were investigated. The ratio of ascorbate to dehydroascorbate was significantly higher in the organically cultivated strawberries. The strawberry extracts decreased the proliferation of both HT29 cells and MCF-7 cells in a dose-dependent way. The inhibitory effect for the highest concentration of the extracts was in the range of 41-63% (average 53%) inhibition compared to controls for the HT29 cells and 26-56% (average 43%) for MCF-7 cells. The extracts from organically grown strawberries had a higher antiproliferative activity for both cell types at the highest concentration than the conventionally grown, and this might indicate a higher content of secondary metabolites with anticarcinogenic properties in the organically grown strawberries. For HT29 cells, there was a negative correlation at the highest extract concentration between the content of ascorbate or vitamin C and cancer cell proliferation, whereas for MCF-7 cells, a high ratio of ascorbate to dehydroascorbate correlated with a higher inhibition of cell proliferation at the second highest concentration. The significance of the effect of ascorbate on cancer cell proliferation might lie in a synergistic action with other compounds.
