Staphylococcus aureus; Mortality; Virology Staphylococcus aureus; Mortalidad; Virología Staphylococcus aureus; Mortalitat; Virologia Background and objective Community-acquired pneumonia (CAP) is a frequent cause of hospitalisation. Several factors, such as pandemics, vaccines and globalisation may lead to changes in epidemiology, clinical presentation, and outcomes of CAP, which oblige to a constant actualisation. We performed this study to analyse how these factors have evolved over a 10-year period. Materials and methods Patients diagnosed with CAP for two 1-year periods that were 10 years apart (2007–2008 and 2017–2018) were included. We compared microbiological information, clinical data and evolutive outcomes in the two periods. A mortality analysis was performed. Results 1043 patients were included: 452 during the first period (2007- 2008), and 591 during the second period (2017–2018). Bacterial aetiology did not change during the 10-year period, besides a slight increase in Staphylococcus aureus (0.9% vs 2.9%, p = 0.026). There was a decline in the proportion of bacteraemia in the second period (14.8% vs 9.6%, p = 0.012). The incidence of complicated pleural effusion and septic shock declined too (6.4% vs 3.6%, p = 0.04 and 15.5% vs 6.3%, p

Modulation of the immune system to prevent lung injury is being widely used against the new coronavirus disease (COVID-19). The primary endpoint was mortality at 7 days after tocilizumab administration. Secondary endpoints were admission to the intensive care unit, development of ARDS and respiratory insufficiency among others.We report the preliminary results from the Vall d'Hebron cohort study at Vall d'Hebron University Hospital, in Barcelona (Spain), including all consecutive patients who had a confirmed SARS-CoV-2 infection and who were treated with tocilizumab until March 25th.82 patients with COVID-19 received at least one dose of tocilizumab. The mean (± SD) age was 59.1 (19.8) years, 63% were male, 22% were of non-Spanish ancestry, and the median (IQR) age-adjusted Charlson index at baseline was 3 (1-4) points. Respiratory failure and ARDS developed in 62 (75.6%) and 45 (54.9%) patients, respectively. Median time from symptom onset to ARDS development was 8 (5-11) days. Mortality at 7 days was 26.8%. Hazard ratio for mortality was 3.3; 95% CI, 1.3-8.5 (age-adjusted hazard ratio for mortality 2.1; 95% CI, 0.8-5.8) if tocilizumab was administered after the onset of ARDS.Early administration of tocilizumab in patients needing oxygen supplementation may be critical to patient recovery. Our preliminary data could inform bedside decisions until more data regarding the precise timing in of initiation of the treatment with tocilizumab.Los tratamientos inmunomoduladores para la prevención del daño pulmonar están siendo ampliamente estudiados contra la COVID-19. El objetivo primario es evaluar la mortalidad a los 7 días después de la administración de tocilizumab. El objetivo secundario es el ingreso en UCI, el desarrollo de distrés respiratorio agudo e insuficiencia respiratoria aguda entre otros.Informamos sobre los resultados preliminares de la cohorte del Hospital Universitario Vall d’Hebron en Barcelona (España), que incluye todos los pacientes consecutivos con infección confirmada por SARS-CoV-2 y que recibieron tratamiento con tocilizumab hasta el 25 de marzo 2020.Ochenta y dos pacientes con COVID-19 recibieron al menos una dosis de tocilizumab. La edad media (±DE) fue de 59,1 (±19,8) años, el 63% eran hombres, 22% correspondía a paciente nacidos fuera de España, y la mediana (RIC) del índice de Charlson ajustado por edad en el momento basal fue de 3 (1-4) puntos. Sesenta y dos pacientes (75,6%) y 45 pacientes (54,9%) desarrollaron insuficiencia respiratoria y distrés respiratorio agudo respectivamente. La mediana de tiempo desde el inicio de los síntomas hasta el desarrollo de ditrés fue de 8 días (5-11). La mortalidad a los 7 días fue del 26,8% La hazard ratio de mortalidad fue del 3,3; IC 95% 1,3-8,5 (la hazard ratio de mortalidad ajustada por edad fue de 2,1; IC 95% 0,8-5,8) si el tocilizumab se administraba después del inicio del distrés respiratorio.La administración precoz de tocilizumab en pacientes con suplementos de oxígeno podría ser crítica para la recuperación de los pacientes. Nuestros datos podrían ayudar a tomar decisiones clínicas hasta que se disponga de más información sobre el momento adecuado para iniciar el tratamiento con tocilizumab.

We report a case of a liver transplant performed in a patient with a history of SARS-CoV-2 infection who presented with a positive polymerase chain reaction test for SARS-CoV-2 on the day of transplant. The transplant procedure was performed without complications, and the patient did not develop symptoms after the initiation of immunosuppression. We also reviewed the literature for similar cases. The emergence of SARS-CoV-2 has forced the medical community to continuously adapt protocols to the current situation. Prudence is needed in immuno- compromised patients, and clinical experience is being built day by day. Thus, a positive polymerase chain reaction test for SARS-CoV-2 in a recipient should not always prevent a liver transplant.

Purpose We aim to assess risk factors related to early readmission in previous hospitalized patients with COVID-19. Methods We analyzed a retrospective cohort of patients with laboratory-confirmed COVID-19 admitted to Vall d’Hebron University Hospital, Barcelona, Spain. Early readmission was defined as the need for hospitalization within a period of 60 days after discharge. A descriptive analysis of the readmission was performed, including hospitalization outcome. We also performed a multivariate logistic regression to define risk factors for readmission Results A total of 629 patients were followed up during 60 days with a readmission cumulative incidence of 5.4% (34 out of 629) and an incidence rate of 0.034 person-years. Main reasons for readmission were respiratory worsening (13, 38.2%), decompensation of previous disease (12, 35.3%) or infectious complications (6, 17.6%). Median time to readmission was 12 days (interquartile range 7–33 days). Prior diagnosis of heart failure (OR 4.09; 95% CI 1.35–12.46; p = 0.013), length of stay during index admission greater than 13 days (OR 2.72; 95% CI 1.21–6.12; p = 0.015), treatment with corticosteroids (OR 2.39; 95% CI 1.01–5.70; p = 0.049) and developing pulmonary thromboembolism (OR 11.59; 95% CI 2.89–46.48; p = 0.001) were the risk factors statistically associated with early readmission. Conclusion Readmission cumulative incidence was 5.4%. Those patients with prior diagnosis of heart failure, length of stay greater than 13 days, treated with corticosteroids or who developed pulmonary thromboembolism might benefit from close monitoring after being discharged.

In the absence of specific guidelines, those applied to these individuals are general prophylaxis guidelines. Cefazolin is the most widely used agent and is replaced by clindamycin or a glycopeptide in beta-lactam allergies. A personalized antibiotic scheme may be considered when colonization by a multidrug-resistant microorganism (MDRO) is suspected. Particularly in methicillin-resistant Staphylococcus aureus (MRSA) colonization or a high prevalence of MRSA-caused PJIs a glycopeptide with cefazolin is recommended. Strategies such as cutaneous decolonization of MDROs, mainly MRSA, or preoperative asymptomatic bacteriuria treatment have also been addressed with debatable results. Some areas of research are early detection protocols in MDRO colonizations by polymerase-chain-reaction (PCR), the use of alternative antimicrobial prophylaxis, and antibiotic-impregnated bone cement in HHA. Given that published evidence addressing PJI prophylactic strategies in PFFs requiring HHA is scarce, PJIs can be reduced by combining different prevention strategies after identifying individuals who will benefit from personalized prophylaxis.

Introduction: Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) are prevalent nosocomial infections with a worrisomely increasing prevalence of multidrug-resistant causative organisms, including those with resistance to carbapenems. The addition of relebactam, a β-lactamase inhibitor, to imipenem treatment restores the antimicrobial activity against the most of multidrug-resistant Gram-negative bacteria, including some carrying β‐lactamase enzyme-type carbapenemases. Areas covered: The aim of this article is to summarize the current evidence regarding imipenem/relebactam for the treatment of HAP/VAP. The authors discuss its chemistry, pharmacokinetics/pharmacodynamics, microbiology, tolerance and clinical efficacy. The results of clinical trials have demonstrated an efficacy of imipenem/relebactam similar to that of its comparator for the treatment of patients with HAP/VAP. Different studies have also shown its good safety profile, which is better than that of the combination of other β‐lactams with other antibiotics. Expert opinion: This drug should be incorporated as a new therapeutic option for the treatment of patients with HAP/VAP, especially as an alternative treatment in patients with confirmed infections caused by multidrug-resistant Gram-negatives.
