Rainfall is a risk factor for sporadic cases of Legionella pneumophila Pneumonia

It is not known whether rainfall increases the risk of sporadic cases of Legionella pneumonia. We sought to test this hypothesis in a prospective observational cohort study of non-immunosuppressed adults hospitalized for community-acquired pneumonia (1995-2011). Cases with Legionella pneumonia were compared with those with non-Legionella pneumonia. Using daily rainfall data obtained from the regional meteorological service we examined patterns of rainfall over the days prior to admission in each study group. Of 4168 patients, 231 (5.5%) had Legionella pneumonia. The diagnosis was based on one or more of the following: sputum (41 cases), antigenuria (206) and serology (98). Daily rainfall average was 0.556 liters/m2 in the Legionella pneumonia group vs. 0.328 liters/m2 for non-Legionella pneumonia cases (p = 0.04). A ROC curve was plotted to compare the incidence of Legionella pneumonia and the weighted median rainfall. The cut-off point was 0.42 (AUC 0.54). Patients who were admitted to hospital with a prior weighted median rainfall higher than 0.42 were more likely to have Legionella pneumonia (OR 1.35; 95% CI 1.02-1.78; p = .03). Spearman Rho correlations revealed a relationship between Legionella pneumonia and rainfall average during each two-week reporting period (0.14; p = 0.003). No relationship was found between rainfall average and non-Legionella pneumonia cases (−0.06; p = 0.24). As a conclusion, rainfall is a significant risk factor for sporadic Legionella pneumonia. Physicians should carefully consider Legionella pneumonia when selecting diagnostic tests and antimicrobial therapy for patients presenting with CAP after periods of rainfall

Streptococcus suis infection and malignancy in man, Spain

Streptococcus suis is an emerging zoonotic agent. Human infection is associated with occupational exposure to swine. Affected persons are usually, but not always, healthy (1,2). Immunosuppressive conditions can predispose persons to S. suis infection, and cancer has classically been associated as a risk factor for S. suis infection (1,2). Nevertheless, the actual number of reported cases is low (27). We describe a severe case of S. suis infection in a man who had not been exposed to swine but for whom disseminated cancer was diagnosed 5 months after the infection

Delayed Cerebral Vasculopathy in Pneumococcal Meningitis: Epidemiology and Clinical Outcome. A Cohort Study

Background: To describe the prevalence, clinical characteristics, impact of systemic steroids exposure and outcomes of delayed cerebral vasculopathy (DCV) in a cohort of adult patients with pneumococcal meningitis (PM). Methods: Observational retrospective multicenter study including all episodes of PM from January 2002 to December 2015. DCV was defined as proven/probable/possible based upon clinical criteria and pathological-radiological findings. DCV-patients and non-DCV-patients were compared by univariate analysis. Results: 162 PM episodes were included. Seventeen (10.5%) DCV-patients were identified (15 possible, 2 probable). At admission, DCV-patients had a longer duration of symptoms (>2 days in 58% vs. 25.5% (p 0.04)), more coma (52.9% vs. 21.4% (p 0.03)), lower median CSF WBC-count (243 cells/uL vs. 2673 cells/uL (p 0.001)) and a higher proportion of positive CSF Gram stain (94.1% vs. 71% (p 0.07)). Median length of stay was 49 vs. 15 days (p 0.001), ICU admission was 85.7% vs. 49.5% (p 0.01) and unfavorable outcome was found in 70.6% vs. 23.8% (p 0.001). DCV appeared 1-8 days after having completed adjunctive dexamethasone treatment (median 2,5, IQR = 1.5-5). Conclusions: One tenth of the PM developed DCV. DCV-patients had a longer duration of illness, were more severely ill, had a higher bacterial load at admission and had a more complicated course. Less than one third of cases recovered without disabilities. The role of corticosteroids in DCV remains to be established. (c) 2020 The Author(s).

Antibiotic treatment versus no treatment for asymptomatic bacteriuria in kidney transplant recipients: a multicenter randomized trial

Background: whether antibiotic treatment of asymptomatic bacteriuria (AB) can prevent acute graft pyelonephritis (AGP) in kidney transplant (KT) recipients has not been elucidated. Methods: in this multicenter, open-label, nonblinded, prospective, noninferiority, randomized controlled trial, we compared antibiotic treatment with no treatment for AB in KT recipients in the first year after transplantation when urinary catheters had been removed. The primary endpoint was the occurrence of AGP. Secondary endpoints included bacteremic AGP, cystitis, susceptibility of urine isolates, graft rejection, graft function, graft loss, opportunistic infections, need for hospitalization, and mortality. Results: we enrolled 205 KT recipients between 2013 and 2015. AB occurred in 41 (42.3%) and 46 (50.5%) patients in the treatment and no treatment groups, respectively. There were no differences in the primary endpoint in the intention-to-treat population (12.2% [5 of 41] in the treatment group vs 8.7% [4 of 46] in the no treatment group; risk ratio, 1.40; 95% confidence interval, 0.40-4.87) or the per-protocol population (13.8% [4 of 29] in the treatment group vs 6.7% [3 of 45] in the no treatment group; risk ratio, 2.07, 95% confidence interval, 0.50-8.58). No differences were found in secondary endpoints, except for antibiotic susceptibility. Fosfomycin (P = .030), amoxicillin-clavulanic (P < .001) resistance, and extended-spectrum β-lactamase production (P = .044) were more common in KT recipients receiving antibiotic treatment for AB. Conclusions: antibiotic treatment of AB was not useful to prevent AGP in KT recipients and may increase antibiotic resistance. However, our findings should be regarded with caution, due to the small sample size analyzed

Proposta d'integració de les competències informàtiques i informacionals (CI2) als estudis de grau i postgrau de la UB

Document elaborat per el grup de treball de Formació d'usuaris del CRAI amb la col·laboració del departament de Biblioteconomia i Documentació, el Servei d'Atenció a l'Estudiant de la UB i la Unitat de Serveis als Usuaris de l'Àrea de Tecnologies.El canvi de paradigma en la docència universitària impulsat per els Acords de Bolonya porta implícita, entre d'altres, la formació en competències informàtiques i informacionals als alumnes de Grau, Postgrau i Doctorat de les universitats. El personal bibliotecari del CRAI de la UB és expert en aquest tipus de formació ja que per una banda es tracta d'habilitats bàsiques en el desenvolupament de la seva professió i per l'altra compta amb molts anys d'experiència acumulada oferint i realitzant sessions de formació per als usuaris de la UB. És a partir del reconeixement d'aquestes condicions del personal de les biblioteques del CRAI que, d'acord amb el vicerectorat de Docència i Convergència Europea de la UB, es va crear un grup de treball, en el qual hi ha participat també el departament de Biblioteconomia i Documentació, el Servei d'Atenció a l'Estudiant (SAE) i la Unitat de Serveis als Usuaris de l'Àrea de Tecnologies, amb l'encàrrec d'elaborar una proposta per implementar la formació en competències informàtiques i informacionals als graus, postgraus i doctorats de la UB. La finalitat: dotar als usuaris de les habilitats necessàries per a la cerca, obtenció, avaluació, processament i comunicació de la informació en qualsevol suport i aconseguir un millor coneixement i per tant una millor utilització dels recursos d¿informació que s'ofereixen des de les biblioteques del CRAI de la UB
