Best practices during COVID-19 pandemic in solid organ transplant programs in Spain.

Clinical management of transplant patients abruptly changed during the first months of COVID-19 pandemic (March to May 2020). The new situation led to very significant challenges, such as new forms of relationship between healthcare providers and patients and other professionals, design of protocols to prevent disease transmission and treatment of infected patients, management of waiting lists and of transplant programs during state/city lockdown, relevant reduction of medical training and educational activities, halt or delays of ongoing research, etc. The two main objectives of the current report are: 1) to promote a project of best practices in transplantation taking advantage of the knowledge and experience acquired by professionals during the evolving situation of the COVID-19 pandemic, both in performing their usual care activity, as well as in the adjustments taken to adapt to the clinical context, and 2) to create a document that collects these best practices, thus allowing the creation of a useful compendium for the exchange of knowledge between different Transplant Units. The scientific committee and expert panel finally standardized 30 best practices, including for the pretransplant period (n = 9), peritransplant period (n = 7), postransplant period (n = 8) and training and communication (n = 6). Many aspects of hospitals and units networking, telematic approaches, patient care, value-based medicine, hospitalization, and outpatient visit strategies, training for novelties and communication skills were covered. Massive vaccination has greatly improved the outcomes of the pandemic, with a decrease in severe cases requiring intensive care and a reduction in mortality. However, suboptimal responses to vaccines have been observed in transplant recipients, and health care strategic plans are necessary in these vulnerable populations. The best practices contained in this expert panel report may aid to their broader implementation.

Cord Blood SARS-CoV-2 IgG Antibodies and Their Association With Maternal Immunity and Neonatal Outcomes

Passive transplacental immunity is crucial for neonatal protection from infections. Data on the correlation between neonatal immunity to SARS-CoV-2 and protection from adverse outcomes is scarce. This work aimed to describe neonatal seropositivity in the context of maternal SARS-CoV-2 infection, seropositivity, and neonatal outcomes. This retrospective nested case-control study enrolled high-risk pregnant women with a SARS-CoV-2 RT-PCR positive test who gave birth at the Instituto Nacional de Perinatología in Mexico City and their term neonates. Anti-SARS-CoV-2 IgG antibodies in maternal and cord blood samples were detected using a chemiluminescent assay. In total, 63 mother-neonate dyads (mean gestational age 38.4 weeks) were included. Transplacental transfer of SARS-CoV-2 IgG occurred in 76% of neonates from seropositive mothers. A positive association between maternal IgG levels and Cycle threshold (Ct) values of RT-qPCR test for SARS-CoV-2 with neonatal IgG levels was observed. Regarding neonatal outcomes, most seropositive neonates did not require any mechanical ventilation, and none developed any respiratory morbidity (either in the COVID-19 positive or negative groups) compared to 7 seronegative neonates. Furthermore, the odds of neonatal respiratory morbidity exhibited a tendency to decrease when neonatal IgG levels increase. These results add further evidence suggesting passive IgG transfer importance.

Manejo de la inmunosupresión en pacientes trasplantados de riñón con COVID19. Estudio multicéntrico nacional derivado del registro COVID de la S.E.N Management of immunosuppressive therapy in kidney transplant recipients with COVID19. A multicentre national study derived form the S.E.N. COVID registry

Introducción: La infección por SARS CoV2 ha impactado de forma importante en los pacientes con trasplante renal causando una elevada mortalidad en los primeros meses de la pandemia. La reducción intencionada de la inmunosupresión se ha postulado como uno de los pilares en el manejo de la infección ante la falta de un tratamiento antiviral dirigido. Ésta se ha modificado de acuerdo con la situación clínica de los pacientes y su efecto sobre la función renal o los anticuerpos anti-HLA a medio plazo no ha sido evaluado. Objetivos: Evaluar los cambios de inmunosupresión realizados durante la infección por SARS-CoV2, así como la función renal y los anticuerpos anti-HLA de los pacientes trasplantados de riñón a los 6 meses del diagnóstico de COVID19. Material y métodos: Estudio retrospectivo, multicéntrico nacional (30 centros) de pacientes trasplantados de riñón con COVID19 desde el 01/02/20 al 31/12/20. Se recogieron las variables de la historia clínica y se incluyeron en una base de datos anonimizada. Se utilizó el programa estadístico SPSS para el análisis de resultados. Resultados: Se incluyeron 615 trasplantados renales con COVID19 (62.6% varones), con una edad media de 57.5 años. El tratamiento inmunosupresor predominante antes del COVID19 era la triple terapia con prednisona, tacrolimus y ácido micofenólico (54.6%) seguido de los regímenes con inbidores m-TOR (18.6%). Tras el diagnóstico de la infección se suspendió el ácido micofenólico en el 73.8% de los pacientes, el inhibidor m-TOR en el 41.4%, tacrolimus en el 10.5% y ciclosporina A en el 10%. A su vez, el 26.9% recibieron dexametasona y al 50.9% se les inició o aumentó la dosis de prednisona basal. La creatinina media antes del diagnóstico de COVID19, en el momento del diagnóstico y a los 6 meses fue de: 1,7±0,8;2.1±1.2 y 1,8±1 mg/dl respectivamente (p<0,001). Al 56.9% de los pacientes (N=350) se les monitorizó los anticuerpos anti-HLA. El 94% (N=329) no presentaron cambios en los anti-HLA, mientras que el 6% (N=21) los positivizaron. De entre los pacientes con anticuerpos donante-específicos post-COVID19 (N=9), a 7 pacientes (3,1%) se les había suspendido un inmunosupresor (en cinco de ellos se suspendió ácido micofenólico y en 2 tacrolimus), a 1 paciente los 2 inmunosupresores (3,4%) y al otro paciente no se le había modificado la inmunosupresión (1,1%), siendo estas diferencias no significativas. Conclusiones: El manejo de la inmunosupresión tras el diagnóstico de COVID19 se basó fundamentalmente en la suspensión de ácido micofenólico con reducciones o suspensiones muy discretas de inhibidores de calcineurina. Este manejo de la inmunosupresión no influyó en la función renal ni en cambios de los anticuerpos anti-HLA a los 6 meses del diagnóstico.

[Prognostic impact of prior cardiopathy in patients hospitalized with COVID-19 pneumonia]. / Repercusión pronóstica de cardiopatía previa en pacientes hospitalizados con neumonía por COVID-19.

Objective: From the onset of COVID-19 pandemic, the presence of previous cardiopathy was thought to be related with a worse prognosis of the disease. We aimed to analyse that theoretical adverse impact in a large cohort of patients. Method: We selected 1065 patients admitted for SARS-CoV-2 pneumonia between March and June 2020, divided in three groups according to (1) absence of cardiopathy, (2) presence of valvular heart disease or ischemic heart disease, or (3) presence of heart failure. We analysed the differences between groups regarding the need for admission in intensive care unit for mechanical ventilation or mortality during admission, or mortality during admission or in the next 6 months. Results: The factors that were associated with a worse prognosis both in acute phase and in the next 6 months were age, male gender, obesity and oncologic disease. The presence of previous cardiopathy did not have an adverse prognostic impact neither initially nor in the short term, in our study. Conclusions: We did not obtain significative association of the presence of cardiopathy with a worse medical evolution, neither in acute phase nor in the short term, of patients admitted for SARS-CoV-2 pneumonia.

Objetivo: Desde el inicio de la pandemia por enfermedad por coronavirus 2019 (COVID-19) se relacionó la presencia de cardiopatía previa con un peor pronóstico de la enfermedad. Nuestro objetivo fue analizar esa posible repercusión desfavorable en una cohorte amplia de pacientes. Método: Se incluyeron 1,065 pacientes ingresados con neumonía por coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2) entre marzo y junio de 2020, divididos en tres grupos, según no tuvieran cardiopatía previa (grupo 1), presentaran cardiopatía valvular o isquémica (grupo 2) o tuvieran insuficiencia cardiaca (grupo 3). Se analizaron las diferencias entre los grupos en cuanto a necesidad de ingreso en unidad de cuidados intensivos para ventilación mecánica o mortalidad durante el ingreso, o mortalidad durante el ingreso o a los seis meses. Resultados: Los factores que se asociaron con un peor pronóstico inicial y a los seis meses fueron la edad, el sexo masculino, la obesidad y la presencia de patología oncológica, sin que la presencia de cardiopatía supusiera una influencia pronóstica negativa inicial ni a corto plazo en nuestro trabajo. Conclusiones: No obtuvimos asociación significativa de la presencia de cardiopatía por si sola con una peor evolución en fase aguda ni a corto plazo de pacientes ingresados con neumonía por SARS-CoV-2.

Breakthrough Infections Following mRNA SARS-CoV-2 Vaccination in Kidney Transplant Recipients.

BACKGROUND: The clinical effectiveness of coronavirus disease 2019 (COVID-19) vaccination in kidney transplant (KT) recipients is lower than in the general population. METHODS: From April to October 2021, 481 KT recipients with COVID-19, included in the Spanish Society of Nephrology COVID-19 Registry, were analyzed. Data regarding vaccination status and vaccine type were collected, and outcomes of unvaccinated or partially vaccinated patients (n = 130) were compared with fully vaccinated patients (n = 351). RESULTS: Clinical picture was similar and survival analysis showed no differences between groups: 21.7% of fully vaccinated patients and 20.8% of unvaccinated or partially vaccinated died (P = 0.776). In multivariable analysis, age and pneumonia were independent risk factors for death, whereas vaccination status was not related to mortality. These results remained similar when we excluded patients with partial vaccination, as well as when we analyzed exclusively hospitalized patients. Patients vaccinated with mRNA-1273 (n = 213) showed a significantly lower mortality than those who received the BNT162b2 vaccine (n = 121) (hazard ratio: 0.52; 95% confidence interval, 0.31-0.85; P = 0.010). CONCLUSIONS: COVID-19 severity in KT patients has remained high and has not improved despite receiving 2 doses of the mRNA vaccine. The mRNA-1273 vaccine shows higher clinical effectiveness than BNT162b2 in KT recipients with breakthrough infections. Confirmation of these data will require further research taking into account the new variants and the administration of successive vaccine doses.

An Assessment of Environmental Knowledge in a Highly Biodiverse Mountainous Region of Mexico

The environmental knowledge of inhabitants residing in a highly biodiverse mountainous region of western Mexico with an important economic forestry sector was investigated. Indices of environmental knowledge, by average and through a factor analysis, were developed and characterized using survey data collected in 2018 and 2021. These indices showed high levels of correlation, and followed similar patterns of distributions. Ordinary least squares and quantile regressions were used to examine social, economic, demographic, and perceptions as determinant factors of the generated indices. Age and education were repeatedly found as important factors influencing environmental knowledge, while income and gender were consistently not significant factors. Furthermore, environmental knowledge was related to quality of life. The index developed by factor analysis generated more significantly stable parameter results across percentiles of environmental knowledge. The indices were recommended for monitoring environmental knowledge in long term studies.

Outpatient prescription patterns of COVID-19 drugs in the metropolitan area of Mexico City.

BACKGROUND: We aimed to describe the use of drugs with apparent efficacy in ambulatory patients with confirmed COVID-19 and the relationship of Google Trends searches with prescriptions and the total number of COVID-19 cases in Mexico City. METHODS: Between March 2020 and February 2021, we surveyed 350 patients confirmed to have COVID-19 across 3 hospitals in Mexico City for their ambulatory prescriptions. We analysed the correlation between prescription patterns of 4 drugs with apparent efficacy against COVID-19, Google Trends searches for these drugs, and the overall number of confirmed COVID-19 cases in Mexico City. RESULTS: We included 350 patients, of whom 59% were women with a median age of 38 years (interquartile range, 29-51), and 72% had a bachelor's degree or higher. There were ambulatory medical prescriptions in 172 (49%) patients, and self-prescriptions were reported in 99 (28%) patients. The prescription rate was high for hydroxychloroquine/azithromycin (19%) and dexamethasone (25%). There was a decrease in the prescription of hydroxychloroquine (P < 0.001) and a strong positive correlation between hydroxychloroquine (r = 0.66; 95% confidence interval, 0.11-0.90; P = 0.02) prescription and online searches for hydroxychloroquine. There was a strong positive correlation between online searches for azithromycin, dexamethasone, ivermectin, and vitamin D and the number of confirmed COVID-19 cases. CONCLUSIONS: During the COVID-19 pandemic, there was a high proportion of prescriptions for hydroxychloroquine/azithromycin and dexamethasone despite their unproven efficacy. Analysis of Google Trends showed a strong correlation between the overall number of confirmed COVID-19 cases and searches for such drugs, suggesting a higher rate of prescriptions. Analysis of online searches could thus help to actively survey public health behaviours in the future.

Inhaled bronchodilators use and clinical course of adult inpatients with Covid-19 pneumonia in Spain: A retrospective cohort study.

BACKGROUND: In the current coronavirus health crisis, inhaled bronchodilators(IB) have been suggested as a possible treatment for patients hospitalized. Patients with evidence of Covid-19 pneumonia worldwide have been prescribed these medications as part of therapy for the disease, an indication for which this medications could be ineffective taken on account the pathophysiology and mechanisms of disease progression. OBJECTIVE: The main objective was to evaluate whether there is an association between IB use and length of stay. Primary end points were the number of days that a patient stayed in the hospital and death as a final event in a time to event analysis. Pneumonia severity, oxygen requirement, involved drugs, comorbidity, historical or current respiratory diagnoses and other drugs prescribed to treat coronavirus pneumonia were also evaluated. METHODS: A descriptive, observational, cross-sectional study was performed in this tertiary hospital in Madrid (Spain). Data were obtained regarding patients hospitalized with Covid-19, excluding those who were intubated. The primary and secondary outcomes such as duration of hospitalization and death were compared in patients who received IB with those in patients who did not. RESULTS: 327 patients were evaluated, mean age was 64.4 ± 15.8 years. Median length of hospitalization stay was 10 days. Of them 292 (89.3%) overcame the disease, the remaining 35 died. Patients who had received IB did not have less mortality rate (odds ratio 0.839; 95% CI: 0.401 to 1.752) and less hospitalization period when compared with patients who did not received IB (odds ratio 1.280; 95% CI: 0.813 to 2.027). There was no significant association between IB use and recovery or death. Hypertension and diabetes were the most common comorbidities. The prevalence of chronic respiratory disease in our cohort was low (21.1%). Anticholinergics were the IB more frequently prescribed for Covid-19 pneumonia. Better response in patients treated with inhaled corticosteroids was not observed. CONCLUSION: Off-label indication of inhaled-bronchodilators for Covid-19 patients are common in admitted patients. Taken on account our results, the use of IB for coronavirus pneumonia apparently is not associated with a significantly patient's improvement. Our study confirms the hypothesis that inhaled bronchodilators do not improve clinical outcomes or reduce the risk of Covid-19 mortality. This could be due to the fact that the virus mainly affects the lung parenchyma and the pulmonary vasculature and probably not the airway. More researches are necessary in order to fill the gap in evidence for this new indication.

T cell-mediated response to SARS-CoV-2 in liver transplant recipients with prior COVID-19.

Whether immunosuppression impairs severe acute respiratory syndrome coronavirus 2-specific T cell-mediated immunity (SARS-CoV-2-CMI) after liver transplantation (LT) remains unknown. We included 31 LT recipients in whom SARS-CoV-2-CMI was assessed by intracellular cytokine staining (ICS) and interferon (IFN)-γ FluoroSpot assay after a median of 103 days from COVID-19 diagnosis. Serum SARS-CoV-2 IgG antibodies were measured by ELISA. A control group of nontransplant immunocompetent patients were matched (1:1 ratio) by age and time from diagnosis. Post-transplant SARS-CoV-2-CMI was detected by ICS in 90.3% (28/31) of recipients, with higher proportions for IFN-γ-producing CD4+ than CD8+ responses (93.5% versus 83.9%). Positive spike-specific and nucleoprotein-specific responses were found by FluoroSpot in 86.7% (26/30) of recipients each, whereas membrane protein-specific response was present in 83.3% (25/30). An inverse correlation was observed between the number of spike-specific IFN-γ-producing SFUs and time from diagnosis (Spearman's rho: -0.418; p value = .024). Two recipients (6.5%) failed to mount either T cell-mediated or IgG responses. There were no significant differences between LT recipients and nontransplant patients in the magnitude of responses by FluoroSpot to any of the antigens. Most LT recipients mount detectable-but declining over time-SARS-CoV-2-CMI after a median of 3 months from COVID-19, with no meaningful differences with immunocompetent patients.

Decreased quality of life and spirometric alterations even after mild-moderate COVID-19.

BACKGROUND: The follow-up of recovered COVID-19 patients is still limited. We aimed to evaluate the changes in quality-of-life (QOL) and spirometric alterations in the convalescent phase of 115 patients with at least 30 days post-COVID-19. METHODS: We included patients with confirmed COVID-19 infection, available past medical records and at least 30 days after the onset of symptoms. All patients were asked to rate their general health condition before and after COVID-19 using the EQ-5D-5L standardized questionary and perform a spirometry at evaluation. RESULTS: In this study, that included 70%(81/115) of patients with mild or moderate COVID-19; there was a severe decrease in QOL up to 56%(64/115). Alterations in usual activities and anxiety/depression were present in 59% of patients with a severe decrease in QOL. The persistence of symptoms was present in 63%(72/115). Restrictive lung impairment was the most common spirometric alteration in 17%(20/115), of whom 65%(13/20) had mild COVID-19. CONCLUSIONS: Spirometric alterations are presented even in mild COVID-19, and more remarkably, there is a high rate of alterations in quality of life after the recovery of this disease.

Economic Consequences of Coronavirus Disease (COVID-19) on Fisheries in the Eastern Mediterranean (Cyprus)

Fisheries are among the sectors hardest-hit by the coronavirus pandemic (COVID-19) crisis due to the sudden decrease in the demand for seafood. This study employs demand-driven and supply-driven input-output models to conduct an economy-wide assessment of the contraction of the fisheries activities in Cyprus, as well as a questionnaire survey to reveal fishermen’s perceptions of COVID-19 crisis impacts. The results at the macroeconomic level reveal that the contraction in the economic output of the fisheries sector does not have any significant impact on the wider economy due to the small size of the sector. However, the COVID-19 crisis has major negative effects on fishermen’s income and the livelihoods of fishers’households. The average gross margin of the interviewed fishermen for March 2020, i.e., the month where a national quarantine and lockdown was imposed, was four times less the average monthly gross margin for the winter period (December 2019–February 2020) and 2.5 times less compared to the average monthly gross margin of 2019. The recessionary impacts of the COVID-19 crisis in conjunction with the chronic challenges that fisheries are currently facing in Cyprus, negatively affect the viability of the sector.

El surgimiento de infecciones originadas por el SARS-CoV-2 en el humano ha desencadenado una serie de conflictos de salud, económicos y sociales en el entorno mundial. El área odontológica debe poseer todo el conocimiento necesario acerca de esta pandemia debido a que, como profesionales de la salud y responsables de la condición bucal de la sociedad, es de vital importancia disminuir el riesgo que presentan las enfermedades crónicas no transmisibles, cáncer, obesidad y otras, así como de los adultos mayores para que no generen un problema de salud severo y que además puedan ser asociadas con la presencia del COVID-19. Es importante conocer cuáles son las pautas por considerar en la práctica odontológica para una atención odontológica oportuna y eficaz manteniendo la bioseguridad del personal de salud. Por lo tanto, se genera esta guía de atención odontológica basada en la evidencia científica publicada para el conocimiento y dominio del profesional de salud oral (AU) The emergence of human infections caused by SRAS-CoV-2 has triggered a series of health, economic and social conflicts in the global environment. The dental area must have all the necessary knowledge about this pandemic because, as a health professional and responsible for the oral condition of society, it is vitally important to reduce the risk of chronic non-communicable diseases, cancer, obesity and others, as well as older adults so that they do not generate a health problem and that may also be associated with the presence of COVID-19. It is important to know the problems of the guidelines to consider in dental practice for effective dental care and biosafety of health personnel. Therefore, this dental care guide is generated based on published scientific evidence for the knowledge and domain of the oral health professional (AU)

[Recommendations on management of the SARS-CoV-2 coronavirus pandemic (Covid-19) in kidney transplant patients]. / Recomendaciones en el manejo de la pandemia por coronavirus SARS-CoV-2 (Covid-19) en pacientes con trasplante renal.

The SARS-CoV-2 (Covid-19) coronavirus pandemic is evolving very quickly and means a special risk for both immunosuppressed and comorbid patients. Knowledge about this growing infection is also increasing although many uncertainties remain, especially in the kidney transplant population. This manuscript presents a proposal for action with general and specific recommendations to protect and prevent infection in this vulnerable population such as kidney transplant recipients.
