RICORS2040 : The need for collaborative research in chronic kidney disease

Chronic kidney disease (CKD) is a silent and poorly known killer. The current concept of CKD is relatively young and uptake by the public, physicians and health authorities is not widespread. Physicians still confuse CKD with chronic kidney insufficiency or failure. For the wider public and health authorities, CKD evokes kidney replacement therapy (KRT). In Spain, the prevalence of KRT is 0.13%. Thus health authorities may consider CKD a non-issue: very few persons eventually need KRT and, for those in whom kidneys fail, the problem is 'solved' by dialysis or kidney transplantation. However, KRT is the tip of the iceberg in the burden of CKD. The main burden of CKD is accelerated ageing and premature death. The cut-off points for kidney function and kidney damage indexes that define CKD also mark an increased risk for all-cause premature death. CKD is the most prevalent risk factor for lethal coronavirus disease 2019 (COVID-19) and the factor that most increases the risk of death in COVID-19, after old age. Men and women undergoing KRT still have an annual mortality that is 10- to 100-fold higher than similar-age peers, and life expectancy is shortened by ~40 years for young persons on dialysis and by 15 years for young persons with a functioning kidney graft. CKD is expected to become the fifth greatest global cause of death by 2040 and the second greatest cause of death in Spain before the end of the century, a time when one in four Spaniards will have CKD. However, by 2022, CKD will become the only top-15 global predicted cause of death that is not supported by a dedicated well-funded Centres for Biomedical Research (CIBER) network structure in Spain. Realizing the underestimation of the CKD burden of disease by health authorities, the Decade of the Kidney initiative for 2020-2030 was launched by the American Association of Kidney Patients and the European Kidney Health Alliance. Leading Spanish kidney researchers grouped in the kidney collaborative research network Red de Investigación Renal have now applied for the Redes de Investigación Cooperativa Orientadas a Resultados en Salud (RICORS) call for collaborative research in Spain with the support of the Spanish Society of Nephrology, Federación Nacional de Asociaciones para la Lucha Contra las Enfermedades del Riñón and ONT: RICORS2040 aims to prevent the dire predictions for the global 2040 burden of CKD from becoming true

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

A língua franca da ciência The international language of science

São feitas considerações sobre a adoção da língua inglesa para publicações científicas cuja temática focalize problemas nosológicos da América Latina. Questiona-se o fato de com essa atitude se objetiva maior visibilidade do artigo e internacionalidade do periódico. Conclui-se que, no nosso ambiente, o ideal seria considerar três "línguas francas" para atingir aquelas finalidades, ou seja, o inglês, o português e o espanhol.<br>There is a trend, with a view to achieving greater scientific visibility and international projection, that favors the adoption of the English language in Brazilian journals dealing with nosological problems. This argument is here questioned. Latin America is a large continent with characteristic health problems. Thus it is to be recommended that scientific public health journals should accept for publication papers written in the three main language: English, Portuguese and Spanish

A crucial RNA-binding lysine residue in the Nab3 RRM domain undergoes SET1 and SET3-responsive methylation

The Nrd1-Nab3-Sen1 (NNS) complex integrates molecular cues to direct termination of noncoding transcription in budding yeast. NNS is positively regulated by histone methylation as well as through Nrd1 binding to the initiating form of RNA PolII. These cues collaborate with Nrd1 and Nab3 binding to target RNA sequences in nascent transcripts through their RRM RNA recognition motifs. In this study, we identify nine lysine residues distributed amongst Nrd1, Nab3 and Sen1 that are methylated, suggesting novel molecular inputs for NNS regulation. We identify mono-methylation of one these residues (Nab3-K363me1) as being partly dependent on the H3K4 methyltransferase, Set1, a known regulator of NNS function. Moreover, the accumulation of Nab3-K363me1 is essentially abolished in strains lacking SET3, a SET domain containing protein that is positively regulated by H3K4 methylation. Nab3-K363 resides within its RRM and physically contacts target RNA. Mutation of Nab3-K363 to arginine (Nab3-K363R) decreases RNA binding of the Nab3 RRM in vitro and causes transcription termination defects and slow growth. These findings identify SET3 as a potential contextual regulator of Nab3 function through its role in methylation of Nab3-K363. Consistent with this hypothesis, we report that SET3 exhibits genetic activation of NAB3 that is observed in a sensitized context

Urinary tract cancer survival in Europe 1999-2007: Results of the population-based study EUROCARE-5

Background This work presents relative survival estimates regarding urinary tract tumours among adult patients (age 65 15 years) diagnosed in Europe. It reports on survival estimates of cases diagnosed in 2000-2007, and on survival time trends from 1999-2001 to 2005-2007. Methods Data on 677,340 adult urinary tract tumour patients, (429,154 cases of invasive and non-invasive bladder and 248,186 cases of invasive kidney cancers) diagnosed between 2000 and 2007 were provided by 86 population-based cancer registries from 29 European countries. The complete approach was used to estimate survival in 2000-2007; the period approach was used to estimate survival over time. Results The age-standardised 5-year relative survival for patients with kidney tumours diagnosed in Europe during 2000-2007 was 60%. The best prognosis was observed in Southern and Central Europe and prognosis improved in all regions along the time period. For invasive and non-invasive patients with bladder tumours combined the age-standardised 5-year relative survival in Europe was 68%. The best prognosis was observed in Southern and Northern Europe. However, in Scotland and The Netherlands the relative survival was significantly lower, although the survival estimates for these two countries were based on invasive tumours only. Conclusions Differences in registration practices affect comparisons of survival values between European countries, especially in patients with urinary bladder cancers. The between-country variation in survival is influenced by the varying use of diagnostic investigation in urinary tract tumours. Further data on stage at diagnosis can help to elucidate the influence of diagnostic intensity or early diagnosis on the survival patterns
