ABSTRACT
In 2020, the COVID-19 pandemic followed a two-wave pattern in most countries. Hospital admission for COVID-19 in one wave or another could have affected mortality, especially among the older persons. The objective of this study was to evaluate whether the admission of older patients during the different waves, before SARS-CoV-2 vaccination was available, was associated with a different mortality. We compared the mortality rates of patients hospitalized during 2020 before (first wave) and after (second wave) July 7, 2020, included in the SEMI-COVID-19 Registry, a large, multicenter, retrospective cohort of patients admitted to 126 Spanish hospitals for COVID-19. A multivariate logistic regression analysis was performed to control for changes in either the patient or disease profile. As of December 26, 2022, 22,494 patients had been included (17,784 from the first wave and 4710 from the second one). Overall mortality was 20.4% in the first wave and 17.2% in the second wave (risk difference (RD) - 3.2%; 95% confidence interval (95% CI) - 4.4 to - 2.0). Only patients aged 70 and older (10,973 patients: 8571 in the first wave and 2386 in the second wave) had a significant reduction in mortality (RD - 7.6%; 95% CI - 9.7 to - 5.5) (unadjusted relative risk reduction: 21.6%). After adjusting for age, comorbidities, variables related to the severity of the disease, and treatment received, admission during the second wave remained a protective factor. In Spain, patients aged 70 years and older admitted during the second wave of the COVID-19 pandemic had a significantly lower risk of mortality, except in severely dependent persons in need of corticosteroid treatment. This effect is independent of patient characteristics, disease severity, or treatment received. This suggests a protective effect of a better standard of care, greater clinical expertise, or a lesser degree of healthcare system overload.

INTRODUCTION: SARS-CoV-2 is a highly contagious virus, and despite professionals' best efforts, nosocomial COVID-19 (NC) infections have been reported. This work aimed to describe differences in symptoms and outcomes between patients with NC and community-acquired COVID-19 (CAC) and to identify risk factors for severe outcomes among NC patients. METHODS: This is a nationwide, retrospective, multicenter, observational study that analyzed patients hospitalized with confirmed COVID-19 in 150 Spanish hospitals (SEMI-COVID-19 Registry) from March 1, 2020, to April 30, 2021. NC was defined as patients admitted for non-COVID-19 diseases with a positive SARS-CoV-2 test on the fifth day of hospitalization or later. The primary outcome was 30-day in-hospital mortality (IHM). The secondary outcome was other COVID-19-related complications. A multivariable logistic regression analysis was performed. RESULTS: Of the 23,219 patients hospitalized with COVID-19, 1,104 (4.8%) were NC. Compared to CAC patients, NC patients were older (median 76 vs. 69 years; p < 0.001), had more comorbidities (median Charlson Comorbidity Index 5 vs. 3; p < 0.001), were less symptomatic (p < 0.001), and had normal chest X-rays more frequently (30.8% vs. 12.5%, p < 0.001). After adjusting for sex, age, dependence, COVID-19 wave, and comorbidities, NC was associated with lower risk of moderate/severe acute respiratory distress syndrome (ARDS) (adjusted odds ratio [aOR]: 0.72; 95% confidence interval [CI]: 0.59-0.87; p < 0.001) and higher risk of acute heart failure (aOR: 1.40; 1.12-1.72; p = 0.003), sepsis (aOR: 1.73; 1.33-2.54; p < 0.001), and readmission (aOR: 1.35; 1.03-1.83; p = 0.028). NC was associated with a higher case fatality rate (39.1% vs. 19.2%) in all age groups. IHM was significantly higher among NC patients (aOR: 2.07; 1.81-2.68; p < 0.001). Risk factors for increased IHM in NC patients were age, moderate/severe dependence, malignancy, dyspnea, moderate/severe ARDS, multiple organ dysfunction syndrome, and shock; odynophagia was associated with lower IHM. CONCLUSIONS: NC is associated with greater mortality and complications compared to CAC. Hospital strategies to prevent NC must be strengthened.

Introduction: Smoking can play a key role in SARS-CoV-2 infection and in the course of the disease. Previous studies have conflicting or inconclusive results on the prevalence of smoking and the severity of the coronavirus disease (COVID-19). Methods: Observational, multicenter, retrospective cohort study of 14,260 patients admitted for COVID-19 in Spanish hospitals between February and September 2020. Their clinical characteristics were recorded and the patients were classified into a smoking group (active or former smokers) or a non-smoking group (never smokers). The patients were followed up to one month after discharge. Differences between groups were analysed. A multivariate logistic regression and Kapplan Meier curves analysed the relationship between smoking and in-hospital mortality. Results: The median age was 68.6 (55.8-79.1) years, with 57.7% of males. Smoking patients were older (69.9 (59.6-78.0 years)), more frequently male (80.3%) and with higher Charlson index (4 (2-6)) than non-smoking patients. Smoking patients presented a worse evolution, with a higher rate of admission to the intensive care unit (ICU) (10.4 vs. 8.1%), higher in-hospital mortality (22.5 vs. 16.4%) and readmission at one month (5.8 vs. 4.0%) than in non-smoking patients. After multivariate analysis, smoking remained associated with these events. Conclusions: Active or past smoking is an independent predictor of poor prognosis in patients with COVID-19. It is associated with higher ICU admissions and in-hospital mortality.
Introducción: El tabaquismo puede tener un papel importante en la infección por SARS-CoV-2 y en el curso de la enfermedad. Los estudios previos muestran resultados contradictorios o no concluyentes sobre la prevalencia de fumar y la severidad en la enfermedad por coronavirus (COVID-19). Material y métodos: Estudio de cohortes observacional, multicéntrico y retrospectivo de 14.260 pacientes que ingresaron por COVID-19 en hospitales españoles desde febrero a septiembre de 2020. Se registraron sus características clínicas y se clasificaron en el grupo con tabaquismo si tabaquismo activo o previo o en el grupo sin tabaquismo si nunca habían fumado. Se realizó un seguimiento hasta un mes después del alta. Se analizaron las diferencias entre grupos. La relación entre tabaquismo y mortalidad intrahospitalaria se valoró mediante una regresión logística multivariante y curvas de Kapplan Meier. Resultados: La mediana de edad fue 68,6 (55,879,1) años, con un 57,7% de varones. El grupo con tabaquismo presentó mayor edad (69,9 (59,678,0 años)), predominio masculino (80,3%) y mayor índice de Charlson (4 (2−6)). La evolución fue peor en estos pacientes, con una mayor tasa de ingreso en UCI (10,4 vs 8,1%), mayor mortalidad intrahospitalaria (22,5 vs 16,4%) y reingreso al mes (5,8 vs 4,0%) que el grupo sin tabaquismo. Tras el análisis multivariante, el tabaquismo permanecía asociado a estos eventos. Conclusiones: El tabaquismo de forma activa o pasada es un factor predictor independiente de mal pronóstico en los pacientes con COVID-19, estando asociada a mayor probabilidad de ingreso en UCI y a mayor mortalidad intrahospitalaria.
ABSTRACT
Objetivo: Conocer las comorbilidades de los pacientes hospitalizados con COVID-19 e identificar cuales se asocian a mayor severidad y/o mortalidad intrahospitalaria. Métodos: Estudio de cohortes retrospectivo en el que se incluyeron todos los pacientes ingresados con COVID-19 desde 1 de marzo del 2020 hasta el 31 mayo de 2020. Se realizó un análisis descriptivo de las comorbilidades y se vio cuales se asocian a una mayor mortalidad intrahospitalaria y/o severidad de la enfermedad mediante un modelo de regresión logística binaria. Resultados: Un total de 336 pacientes fueron incluidos en el estudio de los cuales 52 (15,5%) fallecieron durante el ingreso. Un 58% eran varones, la edad media fue 66 años y el índice Charlson fue de 1. En el análisis multivariante se identificaron como comorbilidades asociadas a mortalidad la edad > 65 años (OR 2,65; p 0,021), el sexo masculino (OR 3,26; p 0,004), la enfermedad cardiovascular ateroesclerótica (OR 2,11; p<0,040) y no ateroesclerótica (OR 6,40; p<0,001) y la neoplasia (OR 5,09; p<0,001). Se asociaron a mayor severidad de la COVID-19 la edad> 65 años (OR 1,87; p 0,033), el sexo masculino (OR 2,86; p <0,001), la obesidad (OR 1,82; p 0,034) y SAOS (OR 5,26; p 0,006). Conclusiones: La enfermedad cardiovascular previa y la neoplasia se asocian a mortalidad intrahospitalaria mientras que la obesidad y el SAOS se asocian a severidad de la enfermedad en pacientes hospitalizados con COVID-19. La edad >65 años y el sexo masculino se asocian a una mayor severidad y mortalidad intrahospitalaria. (AU)
Objective: To evaluate the comorbidities in hospitalized patients with COVID-19 and identify which ones are associated with severe COVID-19 disease and/or in-hospital mortality. Methods: A retrospective cohort study was performed. All patients admitted with confirmed COVID-19 from March 1, 2020 to May 31, 2020 were included. A descriptive analysis of comorbidities was made. We evaluated what comorbidities are associated with in-hospital mortality and/or severe COVID-19 disease using a binary logistic regression model. Results: A total of 336 patients were included in the study: 52 (15,5%) died during hospitalization. Mean age was 66 + 14 years, 58% were men and the Charlson Comorbidity Index was 1. In multivariate analysis, age >65 years (HR 2,65; p 0,021), male sex (HR 3,26; p 0,004), atherosclerotic cardiovascular disease (HR 2,11; p 0,040), non-atherosclerotic cardiovascular disease (HR 6,40; p<0,001) and malignancy (HR 5,09; p< 0,001), were identified as comorbidities associated with in hospital-mortality. Age >65 years (HR 1,87; p 0,033), male sex (HR 2,86; p<0,001), obesity (HR 1,82; p 0,034) and obstructive sleep apnea (HR 5,26; p 0,006) were associated with severe COVID-19 disease. Conclusions: Previous cardiovascular disease and malignancy are risk factors of in-hospital mortality while obesity and obstructive sleep apnea are associated with severe COVID-19 disease in hospitalized patients. Age >65 years and male sex are associated with both. (AU)

(1) Background: This work aims to analyze clinical outcomes according to ethnic groups in patients hospitalized for COVID-19 in Spain. (2) Methods: This nationwide, retrospective, multicenter, observational study analyzed hospitalized patients with confirmed COVID-19 in 150 Spanish hospitals (SEMI-COVID-19 Registry) from 1 March 2020 to 31 December 2021. Clinical outcomes were assessed according to ethnicity (Latin Americans, Sub-Saharan Africans, Asians, North Africans, Europeans). The outcomes were in-hospital mortality (IHM), intensive care unit (ICU) admission, and the use of invasive mechanical ventilation (IMV). Associations between ethnic groups and clinical outcomes adjusted for patient characteristics and baseline Charlson Comorbidity Index values and wave were evaluated using logistic regression. (3) Results: Of 23,953 patients (median age 69.5 years, 42.9% women), 7.0% were Latin American, 1.2% were North African, 0.5% were Asian, 0.5% were Sub-Saharan African, and 89.7% were European. Ethnic minority patients were significantly younger than European patients (median (IQR) age 49.1 (40.5−58.9) to 57.1 (44.1−67.1) vs. 71.5 (59.5−81.4) years, p < 0.001). The unadjusted IHM was higher in European (21.6%) versus North African (11.4%), Asian (10.9%), Latin American (7.1%), and Sub-Saharan African (3.2%) patients. After further adjustment, the IHM was lower in Sub-Saharan African (OR 0.28 (0.10−0.79), p = 0.017) versus European patients, while ICU admission rates were higher in Latin American and North African versus European patients (OR (95%CI) 1.37 (1.17−1.60), p < 0.001) and (OR (95%CI) 1.74 (1.26−2.41), p < 0.001). Moreover, Latin American patients were 39% more likely than European patients to use IMV (OR (95%CI) 1.43 (1.21−1.71), p < 0.001). (4) Conclusion: The adjusted IHM was similar in all groups except for Sub-Saharan Africans, who had lower IHM. Latin American patients were admitted to the ICU and required IMV more often.

The prognosis of a patient with COVID-19 pneumonia is uncertain. Our objective was to establish a predictive model of disease progression to facilitate early decision-making. A retrospective study was performed of patients admitted with COVID-19 pneumonia, classified as severe (admission to the intensive care unit, mechanic invasive ventilation, or death) or non-severe. A predictive model based on clinical, laboratory, and radiological parameters was built. The probability of progression to severe disease was estimated by logistic regression analysis. Calibration and discrimination (receiver operating characteristics curves and AUC) were assessed to determine model performance. During the study period 1152 patients presented with SARS-CoV-2 infection, of whom 229 (19.9%) were admitted for pneumonia. During hospitalization, 51 (22.3%) progressed to severe disease, of whom 26 required ICU care (11.4); 17 (7.4%) underwent invasive mechanical ventilation, and 32 (14%) died of any cause. Five predictors determined within 24 h of admission were identified: Diabetes, Age, Lymphocyte count, SaO2, and pH (DALSH score). The prediction model showed a good clinical performance, including discrimination (AUC 0.87 CI 0.81, 0.92) and calibration (Brier score = 0.11). In total, 0%, 12%, and 50% of patients with severity risk scores ≤ 5%, 6-25%, and > 25% exhibited disease progression, respectively. A risk score based on five factors predicts disease progression and facilitates early decision-making according to prognosis.

OBJETIVO: Conocer las características clínicas y epidemiológicas de los pacientes con enfermedad pulmonar obstructiva crónica (EPOC) y aislamiento de especies de Aspergillus en muestra respiratoria e identificar factores que nos ayuden a diferenciar entre colonización e infección. MÉTODOS: Estudio de cohortes retrospectivo en el que se incluyeron todos los pacientes con EPOC y aislamiento de Aspergillus spp. en muestra respiratoria durante un periodo de 12 años. Se asignaron los pacientes a 2 categorías: colonización y aspergilosis pulmonar (AP), que incluye las diferentes formas de presentación clínica. Se aplicó un modelo de regresión logística binaria para identificar los factores predictores de desarrollo de AP. RESULTADOS: Un total de 123 pacientes fueron incluidos en el estudio: 48 (39%) colonizados y 75 (61%) con AP: 68 con AP invasiva probable y 7 con AP crónica. No hubo correlación entre el riesgo de AP y los estadios espirométricos de la clasificación GOLD. Se identificaron como factores predictores independientes de AP en pacientes con EPOC la oxigenoterapia domiciliaria (OR: 4,39; IC 95%: 1,60-12,01; p = 0,004), las bronquiectasias (OR: 3,61; IC 95%: 1,40-9,30; p = 0,008), la hospitalización en los 3 meses previos al ingreso (OR: 3,12; IC 95%: 1,24-7,87; p = 0,016) y la terapia antifúngica frente a Candida spp. en el mes previo (OR: 3,18; IC 95%: 1,16-8,73; p = 0,024). CONCLUSIONES: La oxigenoterapia continua domiciliaria, las bronquiectasias, la hospitalización en los 3 meses previos al ingreso y la utilización de terapia antifúngica frente a Candida spp. en el mes previo se asocian a mayor riesgo de AP en pacientes con EPOC
OBJECTIVE: To explore the clinical and epidemiological characteristics of chronic obstructive pulmonary disease (COPD) patients with Aspergillus spp. isolation from respiratory samples, and to identify which factors may help us to distinguish between colonisation and infection. METHODS: A retrospective cohort study was performed. All patients with COPD and respiratory isolation of Aspergillus spp. over a 12-year period were included. Patients were assigned to 2 categories: colonisation and pulmonary aspergillosis (PA), which includes the different clinical forms of aspergillosis. A binary logistic regression model was performed to identify the predictive factors of PA. RESULTS: A total of 123 patients were included in the study: 48 (39.0%) with colonisation and 75 (61.0%) with PA: 68 with probable invasive pulmonary aspergillosis and 7 with chronic pulmonary aspergillosis. Spirometric stages of the GOLD classification were not correlated with a higher risk of PA. Four independent predictive factors of PA in COPD patients were identified: home oxygen therapy (OR: 4.39; 95% CI: 1.60-12.01; P = .004), bronchiectasis (OR: 3.61; 95% CI: 1.40-9.30; P = .008), hospital admission in the previous three months (OR: 3.12; 95% CI: 1.24-7.87; P = .016) and antifungal therapy against Candida spp. in the previous month (OR: 3.18; 95% CI: 1.16-8.73; P = .024). CONCLUSIONS: Continuous home oxygen therapy, bronchiectasis, hospital admission in the previous three months and administration of antifungal medication against Candida spp. in the previous month were associated with a higher risk of pulmonary aspergillosis in patients with COPD

INTRODUCTION: Primary lymphoma of the bladder represents 0.2% of all bladder malignancies. Secondary involvement of the bladder by malignant lymphoma occurs in 10% to 50% of cases. Most lymphomas of the bladder are non-Hodgkin's lymphomas of the B-cell type, with preponderance among women. The impact of positron emission tomography (PET) on tumor staging has recently become very important due to its use in the study of diagnosis extension and individual therapy design. CASE PRESENTATION: We report the case of a 79-year-old Caucasian man with intermittent haematuria as the presenting symptom of non-Hodgkin's lymphoma of the bladder. He was first diagnosed with primary lymphoma of the bladder using the current staging method, but a positron emission tomography study subsequently revealed that he instead had a secondary involvement of the bladder. CONCLUSION: The staging of non-Hodgkin's lymphomas, which is useful in order to plan accurate therapy, has been changing since the introduction of positron emission tomography scanning. Primary lymphomas of the bladder, although very rare, may be even more uncommon when this imaging technique is used to assess the extension of the disease. Although the interpretation of this technique has some limitations that should be taken into account, the extensive use of positron emission tomography should nonetheless help improve the diagnosis of this disease.

Hereditary hemorrhagic telangiectasia (HHT) of Rendu-Osler-Weber disease is a multi system vascular dysplasia characterized by the presence of multiple telangiectasias, mainly affecting mucosal tissue and arterial-venous connections. It commonly affects lungs, liver and central nervous system. Bleeding is the most common symptom and its treatment can be surgical or pharmacological. We herein review the systemic therapy that attempts to minimize bleeding as well as blood transfusion therapy. Blood therapy and fibrinolytic treatment especially aminocaproic acid and tranexamic acid are discussed. Danazol, hormone therapy and other less common drugs used in the treatment of HHT are also reviewed.
