Vaccine hesitancy and refusal among parents: An international ID-IRI survey.

INTRODUCTION: Although vaccines are the safest and most effective means to prevent and control infectious diseases, the increasing rate of vaccine hesitancy and refusal (VHR) has become a worldwide concern. We aimed to find opinions of parents on vaccinating their children and contribute to available literature in order to support the fight against vaccine refusal by investigating the reasons for VHR on a global scale. METHODOLOGY: In this international cross-sectional multicenter study conducted by the Infectious Diseases International Research Initiative (ID-IRI), a questionnaire consisting of 20 questions was used to determine parents' attitudes towards vaccination of their children. RESULTS: Four thousand and twenty-nine (4,029) parents were included in the study and 2,863 (78.1%) were females. The overall VHR rate of the parents was found to be 13.7%. Nineteen-point three percent (19.3%) of the parents did not fully comply with the vaccination programs. The VHR rate was higher in high-income (HI) countries. Our study has shown that parents with disabled children and immunocompromised children, with low education levels, and those who use social media networks as sources of information for childhood immunizations had higher VHR rates (p < 0.05 for all). CONCLUSIONS: Seemingly all factors leading to VHR are related to training of the community and the sources of training. Thus, it is necessary to develop strategies at a global level and provide reliable knowledge to combat VHR.

Bronchial Culture Growth From the Donor and Recipient as Predictive Factors in the Detection of Primary Graft Dysfunction and Pneumonia After Lung Transplant.

OBJECTIVES: In this study, our aim was to investigate whether bacterial culture growth from donors and recipients is related to early posttransplant complications and to analyze its role in primary graft dysfunction and posttransplant pneumonia in lung transplant recipients. MATERIALS AND METHODS: This retrospective cohort study included patients diagnosed with end-stage lung disease who received a lung transplant for treatment. We examined relationships between donor bronchial lavage, pretransplant recipient sputum, and recipient posttransplant serial bronchial lavage culture results, as well as the development of both primary graft dysfunction and pneumonia after lung transplant during the early posttransplant period. RESULTS: Our study included 77 patients with median age of 48 years (25%-75% IQR, 34-56 years) and who were mostly men (79.2%; n = 61). Donor culture positivity was 62.3% (n = 48), and the positivity of sputum culture from patients before transplant was 20.8% (n = 16). Compared with that shown in those without versus those with primary graft dysfunction, there were significantly more positive sputum cultures from patients before transplant (P = .003). Recipients with donor culture growth had a longer duration of invasive mechanical ventilation (median of 4 days [IQR, 2-13 days] vs 1 day [IQR, 1-2 days]; P = .001, respectively) than those without. Multivariate logistic analysis identified both donor culture positivity (odds ratio: 3.391; 95% CI, 1.12-20.46; P = .0028) and sputum culture positivity in pretransplant recipient candidates (odds ratio: 6.494; 95% CI, 1.80-36.27; P = .004) as independent predictors of primary graft dysfunction. CONCLUSIONS: Bacterial growth shown in donor bronchial lavage and sputum culture positivity in patients before transplant were found to be independent predictors of primary graft dysfunction in the early posttransplant period. Organism growth in both the donor and the recipient during the pretransplant period are important determinants for the development of primary graft dysfunction.

Infection profile of patients with extracorporeal membrane oxygenation in paediatric cardiac surgery ICU.

AIM: We investigated the risk of increased nosocomial infections and the associated pathogens in patients who underwent paediatric cardiovascular surgery and were put on extracorporeal membrane oxygenation support. We studied the duration of extracorporeal membrane oxygenation use and other variables that may be associated with increased nosocomial infection risk. METHODS: Patients who were treated with an extracorporeal membrane oxygenation in paediatric cardiovascular surgery ICU between 2010 and 2020 were included in this retrospective study. We analysed the site of infection and microbiological profile of infections occurring in these patients according to CDC and National Healthcare Safety Network criteria. RESULTS: The onset of infection development in patients after extracorporeal membrane oxygenation was found to be median 8 (3-15, 25-75 IQR) days in the whole group, and median 11 (3-16, 25-75 IQR) days in those who developed infection without being put on extracorporeal membrane oxygenation. When patients were divided into those with and without infection, duration of ICU was found to be 19 (16-28, IQR 25-75) days in patients with infection vs. 8 (2-16, IQR 25-75; p: <0.001) days in patients without infection. Duration of extracorporeal membrane oxygenation support was found to be 14 (10-25, IQR 25-75) days in patients with infection versus 5 (2-10, IQR 25-75; p: <0.001) days in patients without infection and total hospital stay was 26 (18-33, IQR 25-75) days in patients with infection versus 8 (2-23, IQR 25-75) days in those without infection. A total of 24 patients out of the 70 patients experienced 32 infectious episodes during extracorporeal membrane oxygenation support. Culture-positive infections were detected at a single site in 19 patients, and multiple sites in 5 patients. CONCLUSION: We propose that prolonged extracorporeal membrane oxygenation support is associated with an increased risk of infection. Although extracorporeal membrane oxygenation is a life-saving treatment method, prolonged extracorporeal membrane oxygenation may increase the development of infectious complications and the associated mortality and morbidity of the patient.

Revascularization strategies in patients with infective endocarditis-related ST-elevation myocardial infarction: The STEMI-ENDO Registry.

OBJECTIVE: Infective endocarditis (IE)-related ST elevation myocardial infarction (STEMI) is extremely rare. A clear clinical consensus is lacking regarding the management of this emergency. In this study, we aimed to describe the clinical outcomes of treatment strategies in this patient population. METHODS: The study population comprised 19 retrospectively evaluated patients (nine women; mean age 52±11.8 years) with a diagnosis of IE-related STEMI. Transesophageal echocardiography detected vegetation in all the patients. The study population was divided into two groups on the basis of in-hospital mortality. RESULTS: Major clinical manifestations included dyspnea (89.5%), fever (78.9%), and chest pain (63.2%). Catheter-based coronary angiography was performed in all the patients. The causative agent was isolated in all the cases, and Staphylococcus aureus was identified in seven (36.8%). The most common infarction was in the left anterior descending artery (n=12 [63.2%]). The treatment strategy consisted of mechanical thrombectomy (n=1), valve replacement following stent implantation (n=5), direct balloon angioplasty (n=4), valve replacement along with coronary artery bypass grafting (CABG; n=6), and medical follow-up (n=3). Moreover, thrombolysis in myocardial infarction III flow was significantly higher in the survival group (100% vs. 0%, p<0.001). All these patients preferred CABG or stent implantation for revascularization. CONCLUSION: The current data suggest that a revascularization strategy with stent implantation or revascularization with CABG has a lower mortality rate in patients with IE-related STEMI.

Profiles of multidrug-resistant organisms among patients with bacteremia in intensive care units: an international ID-IRI survey.

Evaluating trends in antibiotic resistance is a requisite. The study aimed to analyze the profile of multidrug-resistant organisms (MDROs) among hospitalized patients with bacteremia in intensive care units (ICUs) in a large geographical area. This is a 1-month cross-sectional survey for blood-borne pathogens in 57 ICUs from 24 countries with different income levels: lower-middle-income (LMI), upper-middle-income (UMI), and high-income (HI) countries. Multidrug-resistant (MDR), extensively drug-resistant (XDR), or pan-drug-resistant isolates were searched. Logistic regression analysis determined resistance predictors among MDROs. Community-acquired infections were comparable to hospital-acquired infections particularly in LMI (94/202; 46.5% vs 108/202; 53.5%). Although MDR (65.1%; 502/771) and XDR (4.9%; 38/771) were common, no pan-drug-resistant isolate was recovered. In total, 32.1% of MDR were Klebsiella pneumoniae, and 55.3% of XDR were Acinetobacter baumannii. The highest MDR and XDR rates were in UMI and LMI, respectively, with no XDR revealed from HI. Predictors of MDR acquisition were male gender (OR, 12.11; 95% CI, 3.025-15.585) and the hospital-acquired origin of bacteremia (OR, 2.643; 95%CI, 1.462-3.894), and XDR acquisition was due to bacteremia in UMI (OR, 3.344; 95%CI, 1.189-5.626) and admission to medical-surgical ICUs (OR, 1.481; 95% CI, 1.076-2.037). We confirm the urgent need to expand stewardship activities to community settings especially in LMI, with more paid attention to the drugs with a higher potential for resistance. Empowering microbiology laboratories and reports to direct prescribing decisions should be prioritized. Supporting stewardship in ICUs, the mixed medical-surgical ones in particular, is warranted.

The cost of one unit blood transfusion components and cost-effectiveness analysis results of transfusion improvement program.

BACKGROUND: This study aims to analyze the cost of the entire transfusion process in Turkey including evaluation of the cost of transfusion from the perspective of hospital management and determination of savings achieved with the transfusion improvement program. METHODS: Invoices, labor, material costs were calculated with micro-costing method, while general production expenses were calculated with gross costing method between January 2018 and December 2019. Unit costs for each blood product were calculated separately by collecting unit acquisition costs, material costs, labor costs, and general production expenses and, then, distributed into six different blood products as follows: erythrocyte suspension, fresh frozen plasma, pooled platelet, apheresis platelet, cryoprecipitate, fresh whole blood. The total costs for 2018 and 2019 were calculated and the savings achieved were estimated. The Turkish Lira was converted into the United States Dollar ($) currency using the purchasing power parity. RESULTS: In 2018/2019, the blood component transfusion cost was $240.90/251.18 for erythrocyte suspension, $120.00/128.67 for fresh frozen plasma, $313.50/322.19 for pooled platelet, $314.24/325.73 for apheresis platelet, $104.95/113.99 for cryoprecipitate, and $189.91/209.09 for fresh whole blood. The total transfusion cost was $6,224,208.33 in 2108 and $5,308,148.43 in 2019. As a result of the transfusion improvement program launched in 2019, the amount of blood components decreased by 23.24%, compared to the previous year, and a saving of $916,059.9 was achieved. CONCLUSION: The transfusion is a burden for both the hospital management systems and the country's economy. To accurately calculate and manage this economic burden is important for sustainable healthcare services.

Evaluation of extensively drug-resistant gram-negative bacteremia among solid-organ transplant recipients: a multicenter study

Background/aim: The aim of this study is to evaluate the distribution, sources, clinical features, and mortality rates of bacteremia due to evaluation of extensively drug-resistant (XDR) gram negative among solid-organ transplant (SOT) recipients. Materials and methods: A retrospective study of SOT recipients with bacteremia due to XDR gram-negative pathogens in 11 centers between 2016 and 2018 was conducted. Patients' records were evaluated. Results: Of 171 bacteremia that occurred in 164 SOT recipients, 93 (56.7%) were liver, 46 (28%) kidney, 14 (8.5%) heart, and 11 (6.7%) lung recipients. Bacteremia episodes were recorded in the first year in 63.7% of the patients (n = 109), early-onset bacteremia was recorded in 45% (n = 77) of the episodes. In multivariate analysis, catheter-associated bacteremia was an independent risk factor for 7-day mortality (p = 0.037), and early-onset bacteremia was found as an independent risk factor for 30-day mortality (p = 0.017). Conclusion: Difficult-to-treat infections due to XDR bacteria in SOT recipients shadow the success of transplantation. Central venous catheters seem to be the main risk factor. Judicious use of medical devices is of pivotal importance.

COVID-19 presenting with diarrhea in a heart transplant patient.

A 55-year-old man who underwent bicaval orthotopic heart transplantation nine months earlier presented with complaints of diarrhea and oliguria. Laboratory findings showed pancytopenia and an elevated creatinine level. Cyclosporine and mycophenolate mofetil were discontinued, and the patient received only everolimus. As he was immunosuppressed and had atypical symptoms during the COVID-19 pandemic, reverse transcriptase-polymerase chain reaction testing was performed, which yielded a positive result. Treatment with hydroxychloroquine and favipiravir were initiated. Although the patient suffered from acute renal failure, his condition showed an improvement after hydration plus a five-day antiviral treatment and, then, treatment was stopped. His COVID-19 test was negative after 10 days of follow-up and treatment, and he was discharged with cyclosporin and mycophenolate mofetil.

Lung Transplantation for Cystic Fibrosis in Turkey: First Report.

OBJECTIVES: Lung transplant is the most important treatment approach that improves the life expectancy and quality of life for patients with cystic fibrosis with end-stage lung disease. In this study, we retros-pectively analyzed patients with cystic fibrosis who were referred to our lung transplant program in Turkey. MATERIALS AND METHODS: We evaluated 14 patients with cystic fibrosis who were referred to our lung transplant clinic between December 2016 and December 2019. The characteristics of the patients at the time of referral to our lung transplant clinic, survival, and lung transplant results were recorded. RESULTS: Four patients died on the wait list, 3 patients were not eligible for lung transplant, and lung transplant was performed in 7 patients. The mean age of all patients was 22.8 years (range, 11-41 years), and the mean age for patients who underwent lung transplant was 27.5 years (range, 21-41 years). The mean time of suitable donor offer or survival life was 140 days in the patients who were referred for lung transplant. The 1-year mortality rate was 28.6% (2 of 7 patients) after lung transplant. One patient died of chronic lung allograft dysfunction at the 25th month after lung transplant. Four patients were alive without any problems. CONCLUSIONS: Lung transplant is the final treatment method for patients with cystic fibrosis with terminal period lung disease. To provide the best benefit, patients should be evaluated for transplant early. Cystic fibrosis care clinics and lung transplant clinics should work in coordination in order to increase the number of lung transplants and improve outcomes.

Consensus Report on Diagnosis, Treatment and Prevention of Infective Endocarditis by Turkish Society of Cardiovascular Surgery (TSCVS), Turkish Society of Clinical Microbiology and Infectious Diseases (KLIMIK), Turkish Society of Cardiology (TSC), Turkish Society of Nuclear Medicine (TSNM), Turkish Society of Radiology (TSR), Turkish Dental Association (TDA) and Federation of Turkish Pathology Societies (TURKPATH) Cardiovascular System Study Group.

Infective endocarditis (IE) is rare, but associated with significant morbidity and mortality rates. Estimates of the incidence of IE in Turkey are compromised by the absence of population-based prospective studies. Due to the frequent presence of predisposing cardiac conditions and higher rates of nosocomial bacteremia in highrisk groups, the incidence of IE is expected to be higher in Turkey. Additionally, while IE generally affects older people in developed countries, it still affects young people in Turkey. In order to reduce the mortality and morbidity, it is critical to diagnose the IE to determine the causative agent and to start treatment rapidly. However, most of the patients cannot be diagnosed in their first visits, about half of them can be diagnosed after three months, and the disease often goes unnoticed. In patients diagnosed with IE, the rate of identification of causative organisms is significantly lower in Turkey than in developed countries. Furthermore, most of the centers do not perform some essential microbiological diagnostic tests as a routine practice. Some antimicrobials that are recommended as the first-line of treatment for IE, particularly antistaphylococcal penicillins, are not available in Turkey. These problems necessitate reviewing the epidemiological, laboratory, and clinical characteristics of IE in our country, as well as the current information about its diagnosis, treatment, and prevention together with local data. Physicians can follow patients with IE in many specialties. Diagnosis and treatment processes of IE should be standardized at every stage so that management of IE, a setting in which many physicians are involved, can always be in line with current recommendations. Study Group for Infective Endocarditis and Other Cardiovascular Infections of the Turkish Society of Clinical Microbiology and Infectious Diseases has called for collaboration of the relevant specialist organizations to establish a consensus report on the diagnosis, treatment, and prevention of IE in the light of current information and local data in Turkey.
