Covid-19 pandemic: from carnival masks to surgical masks.

Given the high transmissibility of SARS-CoV-2, COVID-19 pandemic has a huge impact on our health system. Even in developed countries, strategic resources soon become insufficient. Although people over 60 and with comorbidities are at greater risk of developing severe forms, younger people may also require precious and scarce care. Hence, the World Health Organization recommend tests - PCR and serological tests - for detecting infected people on a large scale. The most common symptoms are fever, fatigue, dry cough, anorexia, myalgia, and dyspnea, with tomographic pulmonary findings being frequent even in asymptomatic cases. The Brazilian Society of Nephrology has published guidelines for the management of hypertensive, diabetic, dialysis, and transplant patients. In its alerts, care and precautions in dialysis units are also being detailed, both for the health team and for the patients. Although important renal manifestations are not yet evident in the admission of positive cases, recent studies with renal patients and performed in nephrology services are listed here. This pandemic lead us to learn from its progress in order to face new challenges in dialysis clinics, transplant services, and intensive care services.

Countermeasures against COVID-19: how to navigate medical practice through a nascent, evolving evidence base - a European multicentre mixed methods study.

OBJECTIVES: In a previously published Delphi exercise the European Pediatric Dialysis Working Group (EPDWG) reported widely variable counteractive responses to COVID-19 during the first week of statutory public curfews in 12 European countries with case loads of 4-680 infected patients per million. To better understand these wide variations, we assessed different factors affecting countermeasure implementation rates and applied the capability, opportunity, motivation model of behaviour to describe their determinants. DESIGN: We undertook this international mixed methods study of increased depth and breadth to obtain more complete data and to better understand the resulting complex evidence. SETTING: This study was conducted in 14 paediatric nephrology centres across 12 European countries during the COVID-19 pandemic. PARTICIPANTS: The 14 participants were paediatric nephrologists and EPDWG members from 12 European centres. MAIN OUTCOME MEASURES: 52 countermeasures clustered into eight response domains (access control, patient testing, personnel testing, personal protective equipment policy, patient cohorting, personnel cohorting, suspension of routine care, remote work) were categorised by implementation status, drivers (expert opinion, hospital regulations) and resource dependency. Governmental strictness and media attitude were independently assessed for each country and correlated with relevant countermeasure implementation factors. RESULTS: Implementation rates varied widely among response domains (median 49.5%, range 20%-71%) and centres (median 46%, range 31%-62%). Case loads were insufficient to explain response rate variability. Increasing case loads resulted in shifts from expert opinion-based to hospital regulation-based decisions to implement additional countermeasures despite increased resource dependency. Higher governmental strictness and positive media attitude towards countermeasure implementation were associated with higher implementation rates. CONCLUSIONS: COVID-19 countermeasure implementation by paediatric tertiary care centres did not reflect case loads but rather reflected heterogeneity of local rules and of perceived resources. These data highlight the need of ongoing reassessment of current practices, facilitating rapid change in 'institutional behavior' in response to emerging evidence of countermeasure efficacy.

[Impact of the COVID-19 pandemic on Spanish Nephrology Services]. / Impacto de la pandemia COVID-19 en los servicios de Nefrología españoles.

The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, has required a rapid and drastic transformation of hospitals, and consequently also of Spanish Nephrology Units, to respond to the critical situation. The Spanish Society of Nephrology conducted a survey directed to the Heads of Nephrology Departments in Spain that addressed the reorganisation of Nephrology departments and activity during the peak of COVID-19 pandemic. The survey has been focused on the integration of nephrologists in COVID-19 teams, nephrology inpatient care activities (elective admissions, kidney biopsies), the performance of elective surgeries such as vascular accesses or implantation of peritoneal catheters, the suspension of kidney transplantation programmes and the transformation of nephrology outpatient clinics. This work details the adaptation and transformation of nephrology services during the COVID-19 pandemic in Spain. During this period, elective admissions to Nephrology Services, elective surgeries and biopsies were suspended, and the kidney transplant programme was scaled back by more than 75%. It is worth noting that outpatient nephrology consultations were carried out largely by telephone. In conclusion, the pandemic has clearly impacted clinical activity in Spanish Nephrology departments, reducing elective activity and kidney transplants, and modifying activity in outpatient clinics. A restructuring and implementation plan in Nephrology focused on telemedicine and/or virtual medicine would seem to be both necessary and very useful in the near future.
