Pneumomediastinum as a complication of SARS-CoV-2 pneumonia

The incidence of pneumomediastinum in hospitalised patients diagnosed with SARS-CoV-2 pneumonia is by no means negligible, much higher compared to the general population. The pathophysiology of pneumomediastinum in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia is explained by the increase in alveolar-interstitial pressure gradient (dry coughing spells, respiratory work, barotrauma from ventilatory support) in the context of particularly "fragile" lungs due to diffuse alveolar-interstitial damage from infectious-inflammatory origin, all of which significantly increases the risk of alveolar wall rupture. The more severe the SARS-CoV-2 pneumonia, the more likely it is that pneumomediastinum will occur. The development of pneumomediastinum in patients with SARS-CoV-2 pneumonia is associated with higher frequencies of death, intensive care unit (ICU) admission and tracheostomy and longer hospital and ICU lengths of stay. In most cases, pneumomediastinum in SARS-CoV-2 pneumonia is a benign and self-limiting process that resolves with conservative treatment. © 2022 Sociedad Madrinela de Neumologia y Cirugia Toracica.

Severe SARS-CoV-2 pneumonia and pneumomediastinum and/or pneumothorax: a prospective observational study in an intermediate respiratory care unit

Introduction: The occurrence of pneumomediastinum (PNMMD) or pneumothorax (PNMTX) was evaluated in patients with severe SARS-CoV-2 pneumonia. Method(s): This is a prospective observational descriptive study that was carried out on patients admitted to the IRCU of a COVID-19 monographic hospital in Madrid from 14/01/2021 to 27/09/2021. All of them had a diagnosis of severe SARS-CoV-2 pneumonia and required NIRS (HFNC, CPAP, BPAP). The incidences of PNMMD and PNMTX, total and according to NIRS, and their impact on the probability of IMV and death were studied. Result(s): (tables 1 and 2) 4.3% (56/1306) developed PNMMD or PNMTX, 3.8% (50) PNMMD, 1.6% (21) PNMTX, and 1.1% (15) PNMMD+PNMTX. 16.1% of patients with PNMMD or PNMTX had HFNC alone (vs 41.7% without PNMMD or PNMTX;p<0.001) and 83.9% CPAP (vs 57.5%;p<0.001). There was a probability of needing IMV of 64.3% among patients with PNMMD or PNMTX (vs 21.0%;p<0.001), and a mortality of 33.9% (vs 10.5%;p<0.001). Conclusion(s): In patients admitted to the IRCU for severe SARS-CoV-2 pneumonia who required NIRS, incidences of 3.8% for PNMMD and 1.6% for PNMTX were observed. LDH was a risk factor for developing PNMMD or PNMTX (median 438 vs 395;p=0.013), and PNMMD (median 438 vs 395;p=0.014). The majority of patients with PNMMD or PNMTX had CPAP as the NIRS device, much more frequently than patients without PNMTX or PNMMD. However, the pressures used in CPAP were even lower in patients with PNMMD or PNMTX (median 8 vs 10;p=0.031). The probabilities of IMV and mortality among patients with PNMMD or PNMTX were 64.3% and 33.9%, respectively, higher than in patients without PNMMD or PNMTX, 21.0% and 10.5%.

Clinical Findings and Outcomes from 1306 Patients with Covid-19 Pneumonia in an Intermediate Respiratory Care Unit: A Prospective, Observational Study

Background: An intermediate respiratory care unit (IRCU) may be a valuable tool for optimizing patient care, allowing to implement standardized algorithm management to decrease clinical failure and mortality. We aimed to describe the practice of noninvasive respiratory strategies (NRS) in a novel facility fully dedicated to COVID-19 and to establish outcomes of these patients Methods: Prospective, observational study performed at one hospital in Spain. We included consecutive patients admitted to IRCU due to COVID-19 requiring NRS between December 2020 and September 2021. Data collected included mode and usage of NRS, endotracheal intubation and mortality to day 30. A multivariable Cox proportional hazards method was used to assess risk factors associated with clinical failure and mortality Findings: 1306 patients with COVID-19 were included. Of them, 64.6% were men and mean age was 54.7 years. During IRCU stay, 345 patients presented a clinical failure, (89.6% intubated;14.5% died). Cox model showed a higher clinical failure in IRCU when time between symptoms onset and hospitalization < 10 days (HR 1.59;95% CI 1.24-2.03;p<0.001) and PaO2/FiO2 <100 (HR 1.59;95% CI 1.27-1.98;p<0.001). Conversely, these variables were not associated with an increased mortality to day 30 Interpretation: IRCU may be a useful option for the multidisciplinary management of COVID-19 patients requiring NRS;thus, reducing ICU overcharge. Men gender, gas-exchange and blood chemistry at admission are associated with worse clinical outcomes, while older age, gas-exchange and blood chemistry are associated with 30-day mortality.

Usefulness of the early combination of non-invasive respiratory therapies in patients with COVID-19

Aim: To determine the effect of the early combination of high flow nasal cannula (HFNC) plus continuous positive airway pressure (CPAP) regarding endotracheal intubation (ETI) and 30-day mortality in patients with SARS-CoV-2 pneumonia. Method(s): Observational study of patients admitted to the intermediate respiratory care unit (IRCU) who received HFNC+CPAP. Two groups were formed according to the time of starting the combined therapy: Early HFNC+CPAP (first 24 h - EHC) and Late HFNC+CPAP (after 24 h - LHC). A multivariate analysis was performed to establish the strength of the association with ETI and 30-day mortality. Result(s): 780 patients were included (502 male, mean age 56.5 +/- 12.9 years). Table 1 shows the baseline characteristics. 273 patients were subjected to ETI, 32.9% in the EHC group vs 38.9% in the LHC group (p 0.05). 30day mortality was 8.2% in the EHC vs 15.5% LHC (p 0.02). Table 2 shows the multivariate analysis. Conclusion(s): The combination of HFNC+CPAP, especially in the first 24 hours after IRCU admission, is a useful tool in the management of SARS-CoV-2 pneumonia.

Clinical characteristics and respiratory care of hospitalized patients according to vaccination status of COVID 19

Although protection of vaccines against COVID-19 has been reported, very little is known about the clinical characteristics of hospitalized vaccinated patients. Method(s): This single-center cohort study of 1888 COVID-19 patients hospitalized at the "Enfermera Isabel Zendal" Emergencies Hospital, Madrid (Spain) was performed between July and September, 2021. It compared the results of 1327 unvaccinated patients to 209 fully vaccinated and 352 partially vaccinated. Vaccines administered were: BNT162b2, ChAdOx1 nCoV-19, mRNA-1273, Ad26.COV2.S. Finding(s): Hospitalized patients' median age was 41 years (IQR 33.0-50.0) for the unvaccinated and 61.0 years (IQR 53.0-67.0) for the fully vaccinated ones. The main comorbidities were obesity, hypertension and diabetes mellitus. The fully vaccinated patients obtained higher C-reactive protein values (median 48.9 mg/l [IQR 21.7-102.9]) and significantly lower for ferritin (median 367.0 ng/ml [IQR 182.0-731.0]) and lactate dehydrogenase (median 269.0 units/l [IQR 218.5-330.5]) values. 266 unvaccinated patients required noninvasive respiratory care, as did 51 partially vaccinated and 30 fully vaccinated patients;78 of the unvaccinated patients also needed invasive respiratory care, as did 16 partially vaccinated and 11 fully vaccinated patients. The fully vaccinated patients were 84% less likely to be admitted to hospital, and protection for those aged <50 years. Interpretation(s): Once hospitalized, the vaccinated patients displayed more protection against requiring respiratory care than the unvaccinated ones, despite being older and having more comorbidities. No differences appeared for the four studied vaccine types.

Pandemia COVID-19: impacto y reacción rápida de la Urología COVID-19 Pandemic: Impact and rapid reaction of Urology

La pandemia COVID-19 causada por el virus SARS-CoV-2 ha ocasionado decenas de miles de muertos en España y logrado colapsar los hospitales de la red sanitaria en la Comunidad de Madrid, debido en gran parte a su particular tendencia a causar neumonías graves con necesidad de soporte ventilatorio. Este hecho ha ocasionado el colapso de nuestro centro, llegando a tener una ocupación del 130% de sus camas por enfermos COVID-19, y causando por tanto el cese absoluto de actividad del servicio de urología, la práctica desaparición de la docencia de los residentes y la incorporación de buena parte de la plantilla de urología al grupo de personal médico que atiende a estos pacientes. Para la recuperación de esta elevada cantidad de actividad suspendida será necesaria una priorización de la patología en base a criterios puramente clínicos, para la cual se proponen tablas que recogen la relevancia de cada patología dentro de cada área de la urología. Herramientas brindadas por la tecnología como la formación online o los simuladores quirúrgicos podrán ser útiles para la necesaria restitución de la formación de residentes.

A participatory tool for assessing land footprint in city-region food systems-A case study from Metropolitan Copenhagen

The ongoing COVID-19 pandemic has exposed the fragility of current food systems to feed populations around the world. Particularly in urban centers, consumers have been confronted with this vulnerability, highlighting reliance on just-in-time logistics, imports and distant primary production. Urban food demand, regional food supply, land use change, and transport strategies are considered key factors for reestablishing resilient landscapes as part of a sustainable food system. Improving the sustainability of food systems in such circumstances entails working on the interrelations between food supply and demand, rural and urban food commodity production sites, and groups of involved actors and consumers. Of special significance is the agricultural land in close proximity to urban centers. Calling for more holistic approaches in the sense of inclusiveness, food security, citizen involvement and ecological principles, this article describes the use of a new decision support tool, the Metropolitan Foodscape Planner (MFP). The MFP features up-to-date European datasets to assess the potential of current agricultural land use to provide food resources (with special attention to both plant- and animal-based products) and meet the demand of city dwellers, and help to empower citizens, innovators, companies, public authorities and other stakeholders of regional food systems to build a more regionalized food supply network. The tool was tested in the context of the food system of the Copenhagen City Region in two collaborative workshops, namely one workshop with stakeholders of the Copenhagen City Region representing food consultancies, local planning authorities and researchers, and one in-person workshop masterclass with MSc students from the University of Copenhagen. Workshop participants used the tool to learn about the impacts of the current food system at the regional and international level with regard to the demand-supply paradigm of city-regions. The ultimate goal was to develop a participatory mapping exercise and test three food system scenarios for a more regionalized and sustainable food system and, therefore, with increased resilience to crises. Results from this implementation also demonstrated the potential of the tool to identify food production sites at local level that are potentially able to feed the city region in a more sustainable, nutritious and way.

Novel teaching resources for the European Open Platform for Prescribing Education (EurOP2E) - a nominal group technique study

Introduction: The European Open Platform for Prescribing Education (EurOP2E) aims to improve and harmonize European clinical pharmacology and therapeutics education by facilitating international collaboration and sharing open educational resources. The COVID-19 pandemic has forced teachers to switch to online teaching, highlighting the need for high-quality online teaching materials. Objectives: The goal of this study was to establish the resources needed to sustain prescribing education during the pandemic and thereafter. Methods: A nominal group technique study was conducted with prescribing teachers from several European countries and combined with thematic analysis. Results: In four meetings, 20 teachers from 15 countries ranked 35 teaching materials. Ten themes were identified: prescribing scenarios;interactivity & gamification;re-usable materials;online case discussions;practical aspects of prescribing;teaching the teacher;knowledge multimedia;topical issues;personalized & evidence-based prescribing;and essential formularies. Conclusion: By making teaching materials related to the learning outcomes of CPT, format of teaching and resource and faculty development openly available, EurOP2E will help to make high-quality prescribing education available to all. The role of the platform will range from facilitating collaboration to educating the teachers and/or providing ready-touse teaching materials.

PREDICTING FACTORS OF PROLONGED MECHANICAL VENTILATION AFTER ENDOVASCULAR TREATMENT IN LARGE VESSEL OCCLUSION STROKE

Background and aims: Intensive Care Units(ICUs) are a necessary resource for many patients with large vessel occlusion stroke(LVOS) after endovascular treatment(EVT). However, ICUs have a limited availability of beds and ventilators, situation that has been worsened by the current Covid-19 pandemic. We analyze predicting factors for prolonged mechanical ventilation(PMV) after EVT in patients with LVOS. Methods: Retrospective study of patients admitted to our stroke center from 2012-2019 for LVOS who were treated with EVT. We identified patients that required PMV(defined as >24h intubation with admission in ICU) after EVT, and evaluated the association with clinical and radiological factors on admission. Results: N=438. 236(53.9%) women. Mean age 69(DE 14.6). 411(93.8%) anterior circulation stroke, 27(6.2%) posterior. 82(19%) required general anesthesia and intraprocedural intubation, and 47 of them(10.7%) required PMV. Median length of stay(LOS) in ICU: 3 days(1-7). 12/47(25.5%) had prolonged LOS for another reason (6 neurological worsening, 4 hemodynamic instability, 1 respiratory infection, 1 no available beds at Stroke Unit). 19/47(44%) died and 22/47(52.4%) were functionally dependent at three months. Factors associated to a higher risk of PMV after EVT were: basilar occlusion (OR=12.3, IC95%[5.3-28.4],p<0,001);ASPECTS ≤7 (OR=3, IC95%[1.4-6.1],p=0,003) and NIHSS ≥18 (OR=2.8, IC95%[1.3- 5.8],p=0,006). Patients with PMV had a higher risk of mortality (OR=6.5, IC95%[3.3-12.8],p<0,001) and functional dependence (OR=5.1, IC95%[2.4-1],p<0,001) at three months. Conclusions: In our study, patients with basilar occlusion, high NIHSS and lower ASPECTS had higher probability of requiring PMV after EVT, which also led to worse outcome. These are aspects to consider in scenarios with limited availability of ICU beds.

IMPROVING ACCESS TO INPATIENT AMBULATORY CARDIAC MONITORING FOR ACUTE STROKE PATIENTS DURING THE COVID-19 PANDEMIC

Introduction Ambulatory cardiac monitoring (ACM) identifies atrial fibrillation (AF) in 10.7% of patients with ischaemic stroke and no prior history of the condition. Prior to the Covid-19 pandemic, there was limited access to inpatient ACM. During the pandemic the stroke unit was provided with rapid access to inpatient ACM. Aims 1. To examine the number of inpatient and outpatient ACM performed during the pandemic and the number of these which positively identified AF. 2. to measure the mean waiting time for the ACM. Methods The records of patients in the six months prior to (n=118) and the five months during the pandemic (n=354) were analysed. Results The proportion of ACM performed as an inpatient increased from 21% to 59% during the pandemic. Inpatient rapid access ACM identified AF in 6% of patients (vs. 0% previously) and all were anticoagu-lated within 14 days of their stroke. Waiting times for inpatient ACM decreased from a mean of 17 to 4 days during the pandemic. Discussion There was a significant shift in clinical practice and diagnostic access to inpatient ACM during the pandemic, resulting in a greater proportion of tests, increased identification of AF and early anticoagulation, leading to improved patient care and potentially preventing further ischaemic events.

Intergenerational leisure and family reconciliation

Scientific literature suggests the contribution to family reconciliation as a motivation for leisure shared by grandparents and grandchildren. However, there are some discrepant results. The study aimed to examine the need for family reconciliation as a practical motivation for grandparents’ and grandchildren’s shared leisure, and its linkage with its frequency, the geographical residential area, and the cohabitation of both generations in the same home. A questionnaire was administered to 357 grandparents of children aged 6 to 12 years residing in northern Spain, and a descriptive study and inferential analysis of the data were performed. The results placed the need for family reconciliation in an intermediate position, below the motivations of entertainment and emotional motivations, but above those related to co-learning and the absence of other people to perform such activities. The need for family reconciliation is associated with the frequency of shared practice, but not with the geographical residential area or the fact that both generations cohabitate at the same address. The possible exceptionality of the current situation, within the framework of COVID-19, which may have produced significant alterations in the grandparent-grandchildren relationship, is discussed, with the consequent need to continue this line of inquiry. © 2021 Universidad de Almeria.

MEASURING PARTICIPATION: A COMPARATIVE STUDY of CITIZEN ENGAGEMENT PROCESSES in URBAN PLANNING

While there is a growing practice of engagement processes in urban planning, with diverse strategies and actions, there are still many questions regarding the evaluation;the gap being how to conclude that a process has been successful or not, and in what terms. In this context, this paper analyses a series of international reference models over the last fifty years, including levels of participation (Arnstein, UN-Habitat, IAP2), key performance indicators (IISD), evaluation guidelines (IOPD) and quality standards and indicators for community engagement (NSfCE, OGP, UNICEF). Based on this analysis, the research proposes an evaluative framework specific for citizen engagement in urban design and planning processes. The framework includes consists of six standards, with quantitative and qualitative indicators to consider both a process's outputs as its outcomes. The standards are: Scope (level of engagement, process planning and structure), inclusion (diversity and quantity of stakeholders by gender, age, stake-holder type and others), mechanisms (typology, diversity and outreach), communication, building capacity (raising awareness and understanding), and impact (contribution to the urban plan). The research applies the framework to conduct a comparative study among cases of engagement processes in municipal-scale urban planning in the Basque Country, Navarre and Cantabria, in the north of Spain. Six case studies include small- and medium-sized towns and cities with a wide range in scale, from 4,000 to 350,000 people, and both pre-COVID and during- COVID experiences. Results reveal tendencies, common benefits and challenges. Conclusions allow for a better understanding of the matter and expect to be useful and transferable to future urban planning-related engagement processes in order to overcome initial preconceptions, avoid false expectations, and better design and undertake them to increase their social impact and contribution to the urban plans they are framed within. © 2021 WITPress.
