RESUMO
BACKGROUND AND OBJECTIVES: Available information about infection after spine instrumentation (IASI) and its management are scarce. We aimed to analyse DAIR (debridement, antibiotics and implant retention) prognosis and evaluate effectiveness of short antibiotic courses on early forms. METHODS: Multicentre retrospective study of patients with IASI managed surgically (January 2010-December 2016). Risk factors for failure were analysed by multivariate Cox regression and differences between short and long antibiotic treatment were evaluated with a propensity score-matched analysis. RESULTS: Of the 411 IASI cases, 300 (73%) presented in the first month after surgery, 48 in the second month, 22 in the third and 41 thereafter. Infections within the first 2 months (early cases) occurred mainly to older patients, with local inflammatory signs and predominance of Enterobacteriaceae, unlike those in the later periods. When managed with DAIR, prognosis of early cases was better than later ones (failure rate 10.4% versus 26.1%, respectively; P = 0.02). Risk factors for DAIR failure in early cases were female sex, Charlson Score, large fusions (>6 levels) and polymicrobial infections (adjusted HRs of 2.4, 1.3, 2.6 and 2.26, respectively). Propensity score matching proved shorter courses of antibiotics (4-6 weeks) as effective as longer courses (failure rates 11.4% and 10.5%, respectively; P = 0.870). CONCLUSIONS: IASIs within the first 2 months could be managed effectively with DAIR and shorter antibiotic courses. Clinicians should be cautious when faced with patients with comorbidities, large fusions and/or polymicrobial infections.

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant disease associated with neurological complications, including cerebral abscesses (CA). They tend to be unique, supratentorial and lobar. While the surgical intervention is a rule of thumb when treating and diagnosing the etiology of these lesions, this is not always possible due to dangerous or inaccessible locations. We report the case of a patient solely treated with empiric antibiotics without stereotaxic intervention and satisfactory results. CASE PRESENTATION: We present the case of a 21-year-old patient with a right thalamic abscess due to HHT and pulmonary arteriovenous malformations, previously embolized, treated solely with antibiotics. At first, we contemplated the possibility of a stereotaxic biopsy, but the high-risk location and the fact that our patient received a previous full course of antibiotic treatment (in another center), made us discard this intervention because of the low diagnostic yield. We started an empiric antibiotic regime. We followed up very closely the clinical and radiological evaluation the next weeks, adjusting our antibiotic treatment when necessary. The results were favorable from both the radiological and clinical aspects and 6 months after the diagnosis the images show its almost complete disappearance. CONCLUSION: Carefully tailored antibiotic-only regime and vigilance of its adverse effects and close radiological following is a good treatment approach when surgery is not an option.

BACKGROUND: Determination of the humoral response to Clostridioides difficile (CD) toxins could be of great value in the management of patients with CD infection (CDI). METHODS: A prospective study was conducted on the clinical characteristics and humoral response in patients with CDI. Determination of ELISA IgG CD anti-toxin B (tgcBiomics, Germany) was performed. The following dilutions were planned for each patient, 1:100, 1: 200, 1: 400, 1: 800: 1: 1600. A significant concentration of antibody was considered to be present in each dilution if an optical density 0.2 units higher than the negative control of the technique was evident. RESULTS: Eighty-five patients were included during the study period, November 2018-February 2020. The median age was 73 years (interquartile range: 62.5-85 years), with female predominance (45 patients, 52.9%). Thirty-nine patients (45.9%) had a severe infection. Seven patients (8.2%) had suffered an episode of CDI in the previous three months. Seventeen patients (20%) had one or more recurrent episodes during the three-month follow-up: No patient died during admission or required surgery for severe-complicated infection. The incidence of recurrence in patients with no antibody detected at 1:400 dilution was 25.4% (16 patients) while it was 4.3% (one patient) in patients with antibody present at that dilution (p = 0.03). Liver cirrhosis was associated with higher humoral response against CD. CONCLUSIONS: Antibodies IgG CD anti-toxin B detection at a dilution of 1:400, using a B ELISA technique, effectively identified patients at increased risk of recurrence. This information could help assist in the management of patients.

INTRODUCTION: liver enzyme elevation has been reported in SARS-CoV-2 disease (COVID-19) in heterogeneous cohorts, mainly from China. Comprehensive reports from other countries are needed. In this study, we dissect the pattern, evolution, and predictive value of such abnormalities in a cohort from Madrid, Spain. METHODS: a retrospective study with a prospective 14-day follow-up of 373 patients with confirmed COVID-19 in five Madrid hospitals, including 50 outpatients. A COVID-19 severe course was defined as the need for mechanical ventilation. RESULTS: a total of 33.1 % of hospitalized patients showed baseline AST elevation and 28.5 % showed ALT elevation, compared with 12 % and 8 % of outpatients (p ≤ 0.001). Baseline AST, ALT and GGT levels correlated with LDH and C-reactive protein (CRP) levels (r ≤ 0.598, p < 0.005). AST elevation was associated with other severity markers such as male sex, lymphopenia, and pneumonia on X-Ray (p < 0.05 for all). ALP and bilirubin levels were rarely increased. Patients with elevated baseline AST showed a progressive normalization of this enzyme and an increase in ALT and GGT levels. Patients with normal baseline AST showed a flattened evolution pattern with levels within the range. Patients with a severe course of COVID-19 more frequently showed elevated baseline AST than those with a milder evolution (54.2 % vs. 25.4 %, p < 0.001). Age, AST and CRP were independent risk factors for a severe course of COVID-19. CONCLUSION: mild liver enzyme elevation is associated with COVID-19 severity. Baseline AST is an independent predictor of severe COVID-19 course, and tends to normalize over time. ALT and GGT show a late elevation.

BACKGROUND: Novel coronavirus disease 2019 (COVID-19) emerged in Wuhan and rapidly spread, affecting >10 million cases worldwide. Caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and primarily manifesting as an acute respiratory failure with interstitial and alveolar pneumonia, it can also affect multiple organs. Kidney involvement was underestimated in early reports and its role remains controversial. The aim of this study was to analyse the role of kidney damage in COVID-19 outcome. METHODS: This is a prospective cohort study of 1603 consecutive patients admitted in a University Reference Hospital in the heart of the European outbreak. RESULTS: Median age was 64 years, 40.4% were female, 15.2% presented diabetes mellitus, 35.7% hypertension and 20.3% obesity. On admission, the prevalence of elevated serum creatinine (sCr), proteinuria, leucocyturia and haematuria were 21.0, 37.8, 31.8 and 45.6%, respectively. In total, 43.5% of those with an elevated sCr had previous chronic kidney disease (CKD) and 11.4% of those with normal sCr developed an in-hospital acute kidney injury (AKI); 17 patients needed acute haemodialysis; and 197 patients died during hospitalization. Cox proportional hazard regression confirmed that elevated baseline sCr [hazard ratio (95% confidence interval) 2.40 (1.79-3.22)], previous CKD [1.59 (1.06-2.37)], haematuria [1 + 1.68 (0.92-3.06), 2-3 + 2.69 (1.49-4.87)] and in-hospital AKI [1.50 (0.92-2.44)] were independent risk factors for in-hospital death after adjusting for age, sex and comorbidity. CONCLUSION: The prevalence of acute and chronic kidney disease on admission and in-hospital AKI is higher than previously reported in Wuhan, and is associated with high in-hospital mortality. We should increase our awareness towards kidney involvement and design specific strategies for management of COVID-19 in these patients.

BACKGROUND: There is limited knowledge about specific risk factors for Clostridium difficile infection (CDI). METHOD: A retrospective study comparing cases of CDI in solid organ transplant (SOT) recipients with controls (SOT recipients who did not present CDI). RESULTS: Thirty patients with SOT from 1340 transplantation recipients had at least 1 episode of CDI (2.23%). The accumulated incidence was 3.06% in liver transplantation, 2.78% in lung transplantation, 2.36% in kidney transplantation, and 0.33% in heart transplantation. Seven (23%) cases occurred during the first 2 months. Fifteen (50%) cases were community acquired. Colonoscopy was performed in 6 (20%) cases, but pseudomembranes were observed in only 1 (16%) case. Independent variables found to be related to CDI were previous treatment with proton pump inhibitors (PPIs; odds ratio [OR] 5.5; 95% confidence interval [CI] 1.2-32.0), immunosuppressive regimen including mycophenolate (OR 5.2; 95%CI 1.1-18), hospitalization during the previous 3 months (OR 5.1; 95%CI 1.1-17), and antibiotic treatment during the previous month (OR 6.7; 95%CI 1.4-23). Five (16.7%) patients did not respond to the initial treatment. Recurrences were noted in 6 (20%) patients. CONCLUSIONS: Liver transplant recipients presented the highest incidence. Risk factors for CDI were previous treatment with PPIs, immunosuppressive regimen containing mycophenolate, prior hospitalization, and prior antibiotic treatment.

A 59-year-old Caucasian male presented with progressive dyspnea, arthralgias and fever for three days. A diastolic regurgitation murmur was detected in the aortic area. A transesophageal echocardiograph showed several vegetations and severe aortic regurgitation. Blood cultures yielded Neisseria gonorrhoeae beta-lactamase negative. The patient had not noticed any urogenital discomfort or urethral discharge. The patient successfully underwent surgery for septal abscess debridement. The patient received ceftriaxone 2 g bid for eight weeks and the clinical follow-up was uneventful. The review of the literature revealed a total of the 38 additional cases reported between 1980 and the present. The majority of the patients were young, male and with native valve involvement. There has been a clear tendency for left-sided valve involvement (especially in the aortic valve). All valve cultures were reported negative despite, in most cases, the marked tissue destruction. Polymerase chain reaction was performed in two patients and positive results were shown in both. Cultures of exudates from other locations were negative in most cases. One striking fact is the high proportion of patients who underwent surgery (72 %). Information regarding antibiotic sensitivity was available in 28 cases, with penicillin resistance reported in six patients (21 %) and intermediate sensitivity in four patients (14 %). Resistance to ciprofloxacin was reported in two cases (7 %). A rapid increase and distribution of isolates resistant to third generation cephalosporins have been recently detected. The mortality is high, particularly taking into account that most were young patients who had not presented previous heart disease.

Background: Recurrent acute cholangitis (RAC) is a relatively uncommon entity that presents significant management difficulties. We present the case of a patient with RAC in whom the number of episodes was reduced after a novel therapeutic procedure. Case report: A 93-year-old male who in June 2019 was admitted for chills without fever, shivering, epigastric abdominal pain and moderate jaundice. Both abdominal ultrasound and CT scan showed intrahepatic and extrahepatic duct dilatation up to the papilla with no evidence of mass at that level. Endoscopic retrograde cholangiopancreatography (ERCP) was performed and abundant biliary sludge was removed. E. coli was identified as the cause of several of the episodes. Some isolates were shown to produce extended spectrum beta-lactamase (ESBL). Papillotomy was performed and plastic prosthesis and later a metallic prosthesis were implanted. Several months later a surgical bypass of the biliary tract was performed due to persistent episodes of cholangitis. When the chronic suppressive antibiotic treatment subsequently instituted to prevent new episodes of cholangitis failed, it was decided to perform a fecal microbiota transplant from a healthy donor and to suspend the chronic suppressive treatment. Since then, she has not presented new episodes of RAC for more than 10 months of clinical follow-up. BLEE-producing E. coli in the gastrointestinal tract could not be eradicated. Comment: Chronic colonization of the biliary tract by certain enterobacteria such as E. coli has been identified as a relevant pathogenic factor in cases of RAC. FMT may be a promising tool to improve the clinical course of patients with RAC.
RESUMO
INTRODUCTION: The evaluation of staging and activity of invasive fungal infection (IFI) is used to adjust the type and duration of antifungal therapy (AT). Typically anatomy-based imaging is used. Positron emission tomography/CT with 18F-fluorodeoxyglucose (18F-FDG PET/CT) not only evaluates more than one body area in one session, but adds functional information to the anatomic data provided by usual imaging techniques and can potentially improve staging of IFI and monitoring of the response to therapy. Our objective is to analyse the impact of the systematic use of 18F-FDG PET/CT in IFI diagnostic and therapeutic management. METHODS AND ANALYSIS: Multicentre prospective cohort study of IFI with performance of systematic 18F-FDG PET/CT at diagnosis and follow-up that will be carried out in 14 Spanish tertiary hospitals. It is planned to include 224 patients with IFI over a 2-year study period. Findings and changes in management before and after 18F-FDG PET/CT will be compared. Additionally, the association of initial quantitative 18F-FDG PET/CT parameters with response to therapy will be evaluated.The primary endpoint is to compare the yield of 18F-FDG PET/CT with standard management without 18F-FDG PET/CT in IFI at initial assessment (staging) and in monitoring the response to treatment.The impact of the results of 18F-FDG PET/CT on the diagnostic-therapeutic management of patients with IFI (added value), as well as the prognostic ability of different quantification parameters of 18F-FDG PET/CT will be secondary endpoints. ETHICS AND DISSEMINATION: The Clinical Research Ethics Committee of Puerta de Hierro-Majadahonda University Hospital approved the protocol of the study at the primary site. We plan to publish the results in high-impact journals. TRIAL REGISTRATION NUMBER: NCT05688592.

Coagulase-negative staphylococci (CoNS) are currently considered typical microorganisms causing infective endocarditis (IE) in patients with prosthetic valves. The objective was to determine variables associated with IE in patients with CoNS bacteremia. We performed an analysis of the clinical characteristics of patients with CoNS bacteremia admitted to a university hospital in Madrid (Spain) from 2021 to December 2022 according to the occurrence of IE. This study is an evaluation of a bacteremia registry. During the study period, 106 patients with CoNS bacteremia were detected. In 85 patients an echocardiogram was performed during hospital admission to rule out IE. Among them, 12 episodes were detected that met IE criteria (14.2%). Of the 6 patients with heart valve prostheses, 5 patients (83.3%) had IE (p < 0.001). Patients with IE more frequently had positive blood cultures more than 12 h after the first draw (58.3% versus 13.4%; p < 0.001). There was a tendency to associate community-acquired bacteremia and to that all blood culture bottles obtained were positive with an increased risk of IE (p = 0.091 and p = 0,057, respectively). Attributable mortality to infection was higher in patients with IE relative to all other patients (16.7% vs. 0%; p = 0.033). The multivariable analysis included having valve prosthesis and persistent bacteremia for more than 12 h. Both were independently associated with IE: valve prosthesis OR 38.6 (95% CI 5.8-258; p < 0.001) and persistent bacteremia OR 2.6 (95% CI 1.1-6.8; p = 0.046). In conclusion, a high percentage of cases of CoNS bacteremia may be due to IE. Some of the variables related to a higher risk of IE, such as having a valvular prosthesis or presenting positive blood cultures for more than 12 h, should lead to rule out or confirm the presence of IE by performing echocardiography.

BACKGROUND: Little is known about the incidence of influenza among admissions to the cardiac intensive care unit (C-ICU), accuracy of clinical suspicion, and influenza vaccination uptake. We evaluated the incidence of influenza at C-ICU admission during the influenza season, potential underdiagnosis, and vaccination uptake. METHODS: Prospective study at five C-ICUs during the 2017-2020 influenza seasons. A nasopharyngeal swab was collected at admission from patients who consented (n = 788). Testing was with Xpert®XpressFlu/RSV. RESULTS: Influenza was detected in 43 patients (5.5%) (40 FluA; 3 FluB) and clinically suspected in 27 (62.8%). Compared to patients without influenza, patients with influenza more frequently had heart failure (37.2% vs 22.8%, P = 0.031), previous contact with relatives with influenza-like illnesses (23.3% vs 12.5%, P = 0.042), antimicrobial use (67.4% vs 23.2%, P <0.01), and need for mechanical ventilation (25.6% vs 14.5%, P = 0.048). Patients received oseltamivir promptly. We found no differences in mortality (11.6% vs 5.2%, P = 0.076). Patients with influenza more frequently had myocarditis (9.3% vs 0.9%, P <0.01) and pericarditis (7.0% vs 0.8%, P = 0.01). Overall, 43.0% of patients (339/788) were vaccinated (51.9% of those with a clear indication [303/584]). CONCLUSION: Influenza seems to be a frequently underdiagnosed underlying condition in admissions to the C-ICU. Influenza should be screened for at C-ICU admission during influenza epidemics.

Infection after spinal instrumentation (IASI) by Cutibacterium spp. is being more frequently reported. The aim of this study was to analyse the incidence, risk factors, clinical characteristics, and outcome of a Cutibacterium spp. IASI (CG) compared with non-Cutibacterium IASI (NCG) infections, with an additional focus on the role of rifampin in the treatment. All patients from a multicentre, retrospective, observational study with a confirmed IASI between January 2010 and December 2016 were divided into two groups: (CG and NCG) IASI. Baseline, medical, surgical, infection treatment, and follow-up data were compared for both groups. In total, 411 patients were included: 27 CG and 384 NCG. The CG patients were significantly younger. They had a longer median time to diagnosis (23 vs. 13 days) (p = 0.025), although 55.6% debuted within the first month after surgery. Cutibacterium patients were more likely to have the implant removed (29.6% vs. 12.8%; p = 0.014) and received shorter antibiotic regimens (p = 0.014). In 33% of Cutibacterium cases, rifampin was added to the baseline therapy. None of the 27 infections resulted in treatment failure during follow-up regardless of rifampin use. Cutibacterium spp. is associated with a younger age and may cause both early and late IASIs. In our experience, the use of rifampin to improve the outcome in the treatment of a Cutibacterium spp. IASI is not relevant since, in our series, none of the cases had therapeutic failure regardless of the use of rifampin.
RESUMO
Introduction: Whole-body autopsies may be crucial to understand coronavirus disease 2019 (COVID-19) pathophysiology. We aimed to analyze pathological findings in a large series of full-body autopsies, with a special focus on superinfections. Methods: This was a prospective multicenter study that included 70 COVID-19 autopsies performed between April 2020 and February 2021. Epidemiological, clinical and pathological information was collected using a standardized case report form. Results: Median (IQR) age was 70 (range 63.75-74.25) years and 76% of cases were males. Most patients (90%,) had at least one comorbidity prior to COVID-19 diagnosis, with vascular risk factors being the most frequent. Infectious complications were developed by 65.71% of the patients during their follow-up. Mechanical ventilation was required in most patients (75.71%) and was mainly invasive. In multivariate analyses, length of hospital stay and invasive mechanical ventilation were significantly associated with infections (p = 0.036 and p = 0.013, respectively). Necropsy findings revealed diffuse alveolar damage in the lungs, left ventricular hypertrophy in the heart, liver steatosis and pre-infection arteriosclerosis in the heart and kidneys. Conclusion: Our study confirms the main necropsy histopathological findings attributed to COVID-19 in a large patient series, while underlining the importance of both comorbid conditions and superinfections in the pathology.
RESUMO
BACKGROUND: Postoperative infections in patients undergoing craniotomy constitute significant complications associated with increased hospital stay and patient morbidity and mortality. Knowing the aetiology of surgical infections after craniotomy may contribute to improving antibiotic prophylaxis and empirical treatment. METHOD: Information relating to surgical infections in patients undergoing craniotomy was obtained from a series of annual surveys on prevalence of infections in Spanish hospitals (EPINE) during the period 1999-2006. The study protocol collected relevant clinical information on patients with infection. Presence of infection was determined according to the Centres for Disease Control infection criteria. RESULTS: During the time period considered, 107 cases of surgical infections in patients undergoing craniotomy were diagnosed. Forty patients were women (37%) and 67 were male (63%). The mean age was 51.7 years (median 55, range 6-86 years). The duration of the intervention was over 180minutes in 49 patients (45.8%).Thirty-eight patients (35.5%) underwent emergency surgery. Seventy-eight patients (73%) received surgical prophylaxis. Thirty-eight patients (35.5%) had superficial infection of the surgical wound, 38 patients (35.5%) had deep wound infection (including bone flap) and 31 patients (29%), postoperative infections of organ or space (meningitis, subdural empyema or brain abscess). The most common aetiology corresponded to staphylococci (50%), mainly S. aureus (one third of them methicillin-resistant), Pseudomonas aeruginosa (11%), Enterobacter spp (10%) and Acinetobacter baumannii (9%). CONCLUSION: Empirical treatment of these infections should include a glycopeptide such as vancomycin and a beta-lactam with coverage against non-fermenting gram-negative bacilli.

BACKGROUND AND OBJECTIVES: To compare the ability of qSOFA, NEWS2, SOFA, LODS, SIRS, APACHE-II and SAPS-II scores. MATERIAL AND METHODS: Analysis of in-hospital mortality of 203 patients admitted to the ICU because of sepsis. The scores were compared according to their application. Discrimination was evaluated with AUC-ROC curve and performance with the Akaike's (AIC) and Bayesian information criterion (BIC). RESULTS: In-hospital mortality was 31.53%. NEWS2 showed better mortality discrimination ability and better performance considering the AIC/BIC criterion for mortality tan qSOFA (AUC-ROC=.615 and .536; P=.039). SOFA presented higher performance and AUC-ROC tan LODS (.776 vs .693; P=.01) and both showed higher discrimination ability than SIRS (AUC-ROC=.521; P<.003). Finally, SAPS-II was able to predict mortality with better performance than APACHE-II and presented higher discrimination capacity but without statistical significance compared (AUROC=.738 for SAPS-II and AUROC=.673 for APACHE-II; P=.08). CONCLUSION: NEWS2 is a better predictor of mortality than qSOFA and its implementation for the early recognition of the septic patient or the patient with higher risk in the emergency and hospitalization wards should be addressed. In addition, given that SOFA and SAPS-II showed better performance and are simpler than LODS and APACHE-II, respectively, both should be considered the scores of choice in this setting.

BACKGROUND: Healthcare workers (HCWs) have been a critical and vulnerable population during SARS-CoV-2 pandemic. The aim of this study was to determine the overall seroprevalence and to evaluate occupational risk factors among HCWs in one of the countries most affected by this pandemic. METHODS: We conducted a seroprevalence study for SARS-CoV-2 in a tertiary hospital in Madrid (Spain) between 24 April and 8 May 2020. A total of 4894 HCWs were invited for serologic testing. Serum samples were tested for SARS-CoV-2 IgM and IgG antibodies using Enzyme Immunoassay (ELISA) and Electro-Chemiluminescence Immunoassay (ECLIA) techniques. We calculated odds ratios to assess association between demographic and occupational characteristics with SARS-CoV-2 seroconversion. RESULTS: We processed 4324 serum samples. Overall, seroprevalence was of 16.6% (95% CI: 15.5-17.7). We found statistically significant differences in SARS-CoV-2 seroprevalence by type of employee, professional category, department and type of activity performed during the pandemic period, while no differences were identified between the personnel working in the COVID-19 wards compared to those working in non-COVID-19 wards. We confirmed 268 (26.7%) infections among 1005 hospital staff members tested by PCR. 60.5% of HCWs infected by SARS-CoV-2, assessed either by PCR or serology, could be considered asymptomatic or paucisymptomatic. CONCLUSIONS: HCWs have an increased risk of SARS-CoV-2 infection but COVID-19 patient exposure was not a determining factor. Universal mask wearing should be mandatory in healthcare settings given the important number of asymptomatic and paucisymptomatic cases.

Severely ill COVID-19 patients are at high risk of nosocomial infections. The aim of the study was to describe the characteristics of candidemia during the pre-pandemic period (January 2019−February 2020) compared to the pandemic period (March 2020−September 2021). Antifungal susceptibilities were assessed using the EUCAST E.Def 7.3.2 broth dilution method. Fluconazole-resistant C. parapsilosis isolates (FRCP) were studied for sequencing of the ERG11 gene. The incidence of candidemia and C. parapsilosis bloodstream infection increased significantly in the pandemic period (p = 0.021). ICU admission, mechanical ventilation, parenteral nutrition and corticosteroids administration were more frequent in patients with candidemia who had been admitted due to COVID-19. Fifteen cases of FRCP fungemia were detected. The first case was recorded 10 months before the pandemic in a patient transferred from another hospital. The incidence of FRCP in patients admitted for COVID-19 was 1.34 and 0.16 in all other patients (p < 0.001). ICU admission, previous Candida spp. colonization, arterial catheter use, parenteral nutrition and renal function replacement therapy were more frequent in patients with candidemia due to FRCP. All FRCP isolates showed the Y132F mutation. In conclusion, the incidence of candidemia experienced an increase during the COVID-19 pandemic and FRCP fungemia was more frequent in patients admitted due to COVID-19.
RESUMO
INTRODUCTION: Knowledge of the microbiology of surgical infections after abdominal surgery can be of use when prescribing effective empirical antibiotic treatments. METHOD: Analysis of surgical infections after abdominal surgery in patients enrolled in the Prevalence of Infections in Spanish Hospitals (EPINE) corresponding to the years 1999-2006. RESULTS: During the period of the study, 2,280 patients who were subjected to upper or lower abdominal tract surgery were diagnosed with an infection at the surgical site (SSI). Eight hundred and eighty three patients (37%) had an operation of the upper abdominal tract (gastric, hepatobiliary, and pancreatic surgery) and 1,447 patients (63%) lower abdominal tract surgery (appendectomy and colon surgery). A total of 2,617 bacterial species were isolated in the 2,280 patients included in the analysis. The most frequent microorganisms isolated were, Escherichia coli (28%), Enterococcus spp. (15%), Streptococcus spp. (8%), Pseudomonas aeruginosa (7%), and Staphylococcus aureus (5%, resistant to methicillin 2%). In the surgical infections after upper abdominal tract procedures, there were a higher proportion of isolations of staphylococci, Klebsiella pneumoniae, Enterobacter spp., Acinetobacter spp. and Candida albicans and less Escherichia coli, Bacteroides fragilis and Clostridium spp. CONCLUSION: The microbiology of SSI produced after upper abdominal tract surgery did not show any significant differences compared to those of the lower tract. However, more cases of SSI were detected due to staphylococci, Klebsiella pneumoniae, Enterobacter spp., Acinetobacter spp. and Candida albicans and less caused by Escherichia coli, Bacteroides fragilis and Clostridium spp.

ABSTRACT: Spain is one of the European countries most largely affected by COVID-19, being Madrid the epicenter. A good knowledge of the main features of hospitalized patients during the complete lockdown should improve the management of new COVID-19 surges.All patients hospitalized at one large tertiary hospital in Madrid for suspected COVID-19 pneumonia from March 1 to May 31 were retrospectively identified.A total of 1752 patients were admitted with suspected pneumonia due to SARS-CoV-2 infection during the 3-month study period. The peak of daily admissions (nâ=â84) was reached on March 24, whereas the maximal cumulative number of hospitalized patients (nâ=â626) occurred on March 30. Overall, 85.3% had a positive PCR test for SARS-CoV-2 at least once during admission. Their median age was 65 (54-77) and 59.9% were male. The median length of hospitalization was of 7 (4-13) days. Roughly 6.5% were admitted at the intensive care unit.Death occurred in 242 (13.8%). Overall, 75% of deaths occurred in patients older than 75 years-old. It was 38.2% in patients hospitalized older than 80 years-old versus 2.2% in patients younger than 60 years-old (pâ<â0.001). Up to 94 (38.8%) of deceased patients had been transferred from nursing homes. The median Charlson co-morbidity score was 6 in deceased patients.The in-hospital mortality rate during the first wave of COVID-19 in Madrid was 14%. It was largely driven by older age, the presence of underlying chronic conditions (≥2) and living at nursing homes.

BACKGROUND: There is limited knowledge about risk factors for Clostridioides difficile infection (CDI) and recurrent CDI in solid organ transplant (SOT) recipients. METHODS: A case-control study of CDI in SOT recipients compared with controls (SOT recipients who did not present CDI). RESULTS: Sixty-seven patients from 1089 SOT recipients (6.2%) suffered at least one episode of CDI. The mean age was 55 ± 12 years and 20 cases (69%) were men. The accumulated incidence was 8% in liver transplantation, 6.2% in lung transplantation, 5.4% in heart transplantation, and 4.7% in kidney transplantation. Twenty-nine cases (43.3%) were diagnosed during the first 3 months after SOT. Forty-one cases (61.2%) were hospital acquired. Thirty-one patients with CDI presented with mild-moderate infection (46.3%), 30 patients with severe infection (44.8%), and 6 patients with severe-complicated disease (9%). Independent variables found to be related with CDI were hospitalization in the previous 3 months (odds ratio: 2.99; [95% confidence interval 1.21-7.37]) and the use of quinolones in the previous month (odds ratio: 3.71 [95% confidence interval 1.16-11.8]). Eleven patients (16.4%) had at least one recurrence of CDI. Previous treatment with amoxicillin-clavulanate, severe-complicated index episode, and high serum creatinine were associated with recurrent CDI in the univariant analysis CONCLUSIONS: Liver transplant recipients presented the highest incidence of CDI among SOT recipients. Risk factors for CDI were hospitalization in the previous 3 months and the use of quinolones in the previous month.
