Understanding and managing uncertainty and variability for wastewater monitoring beyond the pandemic : lessons learned from the United Kingdom national COVID-19 surveillance programmes
The COVID-19 pandemic has put unprecedented pressure on public health resources around the world. From adversity, opportunities have arisen to measure the state and dynamics of human disease at a scale not seen before. In the United Kingdom, the evidence that wastewater could be used to monitor the SARS-CoV-2 virus prompted the development of National wastewater surveillance programmes. The scale and pace of this work has proven to be unique in monitoring of virus dynamics at a national level, demonstrating the importance of wastewater-based epidemiology (WBE) for public health protection. Beyond COVID-19, it can provide additional value for monitoring and informing on a range of biological and chemical markers of human health. A discussion of measurement uncertainty associated with surveillance of wastewater, focusing on lessons-learned from the UK programmes monitoring COVID-19 is presented, showing that sources of uncertainty impacting measurement quality and interpretation of data for public health decision-making, are varied and complex. While some factors remain poorly understood, we present approaches taken by the UK programmes to manage and mitigate the more tractable sources of uncertainty. This work provides a platform to integrate uncertainty management into WBE activities as part of global One Health initiatives beyond the pandemic

Prognostic impact of KMT2E transcript levels on outcome of patients with acute promyelocytic leukaemia treated with all-trans retinoic acid and anthracycline-based chemotherapy: An International Consortium on Acute Promyelocytic Leukaemia study
The KMT2E (MLL5) gene encodes a histone methyltransferase implicated in the positive control of genes related to haematopoiesis. Its close relationship with retinoic acid-induced granulopoiesis suggests that the deregulated expression of KMT2E might lead acute promyelocytic leukaemia (APL) blasts to become less susceptible to the conventional treatment protocols. Here, we assessed the impact of KMT2E expression on the prognosis of 121 APL patients treated with ATRA and anthracycline-based chemotherapy. Univariate analysis showed that complete remission (P聽=聽0路006), 2-year overall survival (OS) (P聽=聽0路005) and 2-year disease-free survival (DFS) rates (P聽=聽0路037) were significantly lower in patients with low KMT2E expression; additionally, the 2-year cumulative incidence of relapse was higher in patients with low KMT2E expression (P聽=聽0路04). Multivariate analysis revealed that low KMT2E expression was independently associated with lower remission rate (odds ratio [OR]: 7路18, 95% confidence interval [CI]: 1路71-30路1; P聽=聽0路007) and shorter OS (hazard ratio [HR]: 0路27, 95% CI: 0路08-0路87; P聽=聽0路029). Evaluated as a continuous variable, KMT2E expression retained association with poor remission rate (OR: 10路3, 95% CI: 2路49-43路2; P聽=聽0路001) and shorter survival (HR: 0路17, 95% IC: 0路05-0路53; P聽=聽0路002), while the association with DFS was of marginal significance (HR: 1路01; 95% CI: 0路99-1路02; P聽=聽0路06). In summary, low KMT2E expression may predict poor outcome in APL patients

High 螖np73/TAp73 ratio is associated with poor prognosis in acute promyelocytic leukemia
The TP73 gene transcript is alternatively spliced and translated into the transcriptionally active (TAp73) or inactive (螖Np73) isoforms, with opposite effects on the expression of p53 target genes and on apoptosis induction. The imbalance between 螖Np73 and TAp73 may contribute to tumorigenesis and resistance to chemotherapy in human cancers, including hematologic malignancies. In acute promyelocytic leukemia (APL), both isoforms are expressed, but their relevance in determining response to therapy and contribution to leukemogenesis remains unknown. Here, we provide the first evidence that a higher 螖Np73/TAp73 RNA expression ratio is associated with lower survival, lower disease-free survival, and higher risk of relapse in patients with APL homogeneously treated with all-trans retinoic acid and anthracycline-based chemotherapy, according to the International Consortium on Acute Promyelocytic Leukemia (IC-APL) study. Cox proportional hazards modeling showed that a high 螖Np73/TAp73 ratio was independently associated with shorter overall survival (hazard ratio, 4.47; 95% confidence interval, 1.64-12.2; P = .0035). Our data support the hypothesis that the 螖Np73/TAp73 ratio is an important determinant of clinical response in APL and may offer a therapeutic target for enhancing chemosensitivity in blast cells
