The effect of the COVID-19 pandemic on pediatric emergency admissions and tendency towards prescribing antibiotics

Aim: To determine the changes in the diagnoses of patients admitted to pediatric emergency department due to infection and the change in the tendency towards prescribing antibiotics during the COVID-19 pandemic. Methods: Age, gender and the diagnoses of and the antibiotics prescribed for patients under the age of 18 who admitted to the pediatric emergency department on two separate days before and during the pandemic period were compared retrospectively. Results: It was found that the admissions to the pediatric emergency department decreased by 83% during the pandemic period compared to the pre-pandemic period. Upper respiratory tract infection (URTI) was diagnosed in 61.6% of the patients during the pre-pandemic period compared to 32.6% of the patients during the pandemic periods, indicating a statistically significant difference between the groups (p<0.001). The percentage of patients diagnosed with paranasal infection in the pandemic period was also significantly lower than in the pre-pandemic period. On the other hand, the percentages of patients diagnosed with urinary infection and diagnoses other than infection in the pandemic period were significantly higher than in the pre-pandemic period. Additionally, the percentage of patients who were prescribed amoxicillin-clavulanic acid (CAM) was significantly higher, whereas the percentage of patients who were prescribed Clarithromycin was significantly lower in the pandemic period than in the pre-pandemic period. Furthermore, it was determined that Oseltamivir was not prescribed during the pandemic period. Conclusions: Quarantines imposed due to the COVID-19 pandemic and the use of masks have reduced the incidence of upper and lower respiratory tract infections. In parallel, it was determined that the percentage of patients presented to the pediatric emergency department with the diagnosis of non-infectious diagnoses has increased. This result has been attributed to the use of masks and the attention paid to the hygiene, which caused a decrease in the incidence of infectious diseases, influenza in particular

Predictive performance of CT for adverse outcomes among COVID-19 suspected patients: a two-center retrospective study

The aim of the study was to compare the performance of various computed tomography (CT) reporting tools, including zonal CT visual score (ZCVS), the number of involved lobes, and Radiological Society of North America (RSNA) categorization in predicting adverse outcomes among patients hospitalized due to the lower respiratory symptoms during the coronavirus disease 2019 (COVID-19) pandemic. A total of 405 patients admitted with severe respiratory symptoms who underwent a chest CT were enrolled. The primary adverse outcome was intensive care unit (ICU) admission of patients. Predictive performances of reporting tools were compared using the area under the receiver operating characteristic curves (AUC ROC). Among the 405 patients, 39 (9.63%) required ICU support during their hospital stay. At least two or more observers reported a typical and indeterminate COVID-19 pneumonia CT pattern according to RSNA categorization in 70% (285/405) of patients. Among these, 63% (179/285) had a positive polymerase chain reaction (PCR test for the SARS-CoV-2 virus. The median number of lobes involved according to CT was higher in patients who required ICU support (median interquartile range [IQR], 5[3; 5] vs. 3[0; 5]). The median ZCVS score was higher among the patients that subsequently required ICU support (median [IQR], 4[0; 12] vs. 13[5.75; 24]). The bootstrap comparisons of AUC ROC showed significant differences between reporting tools, and the ZCVS was found to be superior (AUC ROC, 71-75%). The ZCVS score at the first admission showed a linear and significant association with adverse outcomes among patients with the lower respiratory tract symptoms during the COVID-19 pandemic

MixInYeast: A Multicenter Study on Mixed Yeast Infections

Invasive candidiasis remains one of the most prevalent systemic mycoses, and several studies have documented the presence of mixed yeast (MY) infections. Here, we describe the epidemiology, clinical, and microbiological characteristics of MY infections causing invasive candidiasis in a multicenter prospective study. Thirty-four centers from 14 countries participated. Samples were collected in each center between April to September 2018, and they were sent to a reference center to confirm identification by sequencing methods and to perform antifungal susceptibility testing, according to the European Committee on Antimicrobial Susceptibility Testing (EUCAST). A total of 6895 yeast cultures were identified and MY occurred in 150 cases (2.2%). Europe accounted for the highest number of centers, with an overall MY rate of 4.2% (118 out of 2840 yeast cultures). Of 122 MY cases, the most frequent combinations were Candida albicans/C. glabrata (42, 34.4%), C. albicans/C. parapsilosis (17, 14%), and C. glabrata/C. tropicalis (8, 6.5%). All Candida isolates were susceptible to amphotericin B, 6.4% were fluconazole-resistant, and two isolates (1.6%) were echinocandin-resistant. Accurate identification of the species involved in MY infections is essential to guide treatment decisions

Self-reported antibiotic stewardship and infection control measures from 57 intensive care units: An international ID-IRI survey

We explored the self-reported antibiotic stewardship (AS), and infection prevention and control (IPC) activities in intensive care units (ICUs) of different income settings. A cross-sectional study was conducted using an online questionnaire to collect data about IPC and AS measures in participating ICUs. The study participants were Infectious Diseases-International Research Initiative (IDI-IR) members, committed as per their institutional agreement form. We analyzed responses from 57 ICUs in 24 countries (Lower-middle income (LMI), n = 13; Upper-middle income (UMI), n = 33; High-income (HI), n = 11). This represented (similar to 5%) of centers represented in the ID-IRI. Surveillance programs were implemented in (76.9%-90.9%) of ICUs with fewer contact precaution measures in LMI ones (p = 0.02); (LMI:69.2%, UMI:97%, HI:100%). Participation in regional antimicrobial resistance programs was more significantly applied in HI (p = 0.02) (LMI:38.4%,UMI:81.8%,HI:72.2%). AS programs are implemented in 77.2% of institutions with AS champions in 66.7%. Infectious diseases physicians and microbiologists are members of many AS teams (59%&50%) respectively. Unqualified healthcare professionals(42.1%), and deficient incentives(28.1%) are the main barriers to implementing AS. We underscore the existing differences in IPC and AS programs' implementation, team composition, and faced barriers. Continuous collaboration and sharing best practices on APM is needed. The role of regional and international organizations should be encouraged. Global support for capacity building of healthcare practitioners is warranted.

An adult onset Still's disease mimicking pneumonia.

Adult onset Still's disease is a rare systemic inflammatory disease of unknown origin. It is common to involve liver and spleen, and less often lungs. A 24-year-old man presenting with spiking fever, pulmonary infiltrations, and pleural effusion on the right side mimicking pneumonia. All serologic tests of infectious causes, antinuclear antibody, and rheumatoid factor were negative. He was diagnosed as Adult onset Still's disease according to the criteria of Yamaguchi. Adult onset Still's disease is considering in the differential diagnosis pneumonia that is unresponsive to antimicrobial treatment, negative cultures and serologically diagnostic laboratory tests, and high-level serum ferritin

In vitro activities of colistin combined with imipenem, tigecycline or cefoperazone-sulbactam against multidrug-resistant Acinetobacter baumannii blood-stream isolates

Acinetobacter baumannii has emerged as one of the most important nosocomial pathogens and multi-drug resistant (MDR) isolates are of great concern worldwide. The aim of the present study was to investigate the in vitro synergistic activity of colistin in combination with other antibiotics against MDR A. baumannii blood stream isolates. A total of 54 non-duplicate, MDR A. baumannii isolates from blood culture specimens obtained between June 2011 and July 2012 were included in the study. In vitro synergistic activity of colistin in combination with imipenem, tigecycline or cefoperazone-sulbactam against study isolates was investigated by Etest superimposing method and the fractional inhibitory concentration (FIC) index was calculated for each antibiotic combination. The most frequent synergistic effect of colistin was found in combination with tigecycline in only 7 isolates (13.0%). All three antibiotics were found to have synergistic effect with colistin in four isolates (7.4%). Of isolates, 46 (85.2%) showed additive effect of colistin in combination with cefoperazone-sulbactam or tigecycline, 45 (83.3%) with imipenem. We found synergistic activity of colistin with other study antibiotics in only a small number of isolates. Although Etest method is a practical method to investigate the synergistic activity, in case of choosing empirical treatment, colistin in combination with another antibiotic may be preferred.

Antibiotic use and Influencing Factors Among Hospitalized Patients with COVID-19: A Multicenter Point-Prevalence Study from Turkey

Background: Broad-spectrum empirical antimicrobials arc frequently prescribed for patients with coronavirus disease 2019 (COVID-19) despite the lack of evidence for bacterial coinfection. Aims: We aimed to cross-sectionally determine the frequency of antibiotics use, type of antibiotics prescribed, and the factors influencing antibiotics use in hospitalized patients with COVID-19 confirmed by polymerase chain reaction. Study Design: The study was a national, multicenter, retrospective. and single-day point prevalence study. Methods: This was a national, multicenter, retrospective, and single-day point-prevalence study, conducted in the 24-h period between 00:00 and 24:00 on November 18, 2020, during the start of the second COVID-19 peak in Turkey. Results: A total of 1500 patients hospitalized with a diagnosis of COVID-19 were included in the study. The mean age +/- standard deviation of the patients was 65.0 +/- 15.5, and 56.2% (n = 843) of these patients were men. Of these hospitalized patients, 11.9% (n = 178) were undergoing invasive mechanical ventilation or ECMO. It was observed that 1118 (74.5%) patients were receiving antibiotics, of which 416 (372%) were prescribed a combination of antibiotics. In total, 71.2% of the patients had neither a clinical diagnosis nor microbiological evidence for prescribing antibiotics. In the multivariate logistic regression analysis, hospitalization in a state hospital (p 0.001), requiring any supplemental oxygen (p = 0.005). presence of moderate/diffuse lung involvement (p 0.001), C-reactive protein >10 ULT coefficient (p 0.001), lymphocyte count 800 (p = 0.007), and clinical diagnosis and/or confirmation by culture (p 0.001) were found to be independent factors associated with increased antibiotic use. Conclusion: The necessity of empirical antibiotics use in patients with COVID-19 should be reconsidered according to their clinical, imaging, and laboratory findings

A novel id-iri score: development and internal validation of the multivariable community acquired sepsis clinical risk prediction model

El-Sokkary, Rehab/0000-0002-8135-7671; Uysal, Serhat/0000-0002-4294-5999WOS: 000520706000011PubMed: 31823148We aimed to develop a scoring system for predicting in-hospital mortality of community-acquired (CA) sepsis patients. This was a prospective, observational multicenter study performed to analyze CA sepsis among adult patients through ID-IRI (Infectious Diseases International Research Initiative) at 32 centers in 10 countries between December 1, 2015, and May 15, 2016. After baseline evaluation, we used univariate analysis at the second and logistic regression analysis at the third phase. in this prospective observational study, data of 373 cases with CA sepsis or septic shock were submitted from 32 referral centers in 10 countries. the median age was 68 (51-77) years, and 174 (46,6%) of the patients were females. the median hospitalization time of the patients was 15 (10-21) days. Overall mortality rate due to CA sepsis was 17.7% (n = 66). the possible predictors which have strong correlation and the variables that cause collinearity are acute oliguria, altered consciousness, persistent hypotension, fever, serum creatinine, age, and serum total protein. CAS (%) is a new scoring system and works in accordance with the parameters in third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). the system has yielded successful results in terms of predicting mortality in CA sepsis patients
