Risk Factors and Characteristics of Candidemia After Cardiac Surgery in Pediatric Patients in Central Israel.

BACKGROUND: Candidemia is a serious complication in pediatric patients with congenital heart defects (CHD) after cardiac surgery. Information about the epidemiology, clinical characteristics and risk factors for candidemia in this vulnerable population remains limited. METHODS: This retrospective case-control study was conducted in 2 pediatric intensive care units between 2004 and 2019. All patients <18 years old who developed candidemia following cardiac surgery were included. Each case was matched with 2 control patients based on age and date of surgery. Multivariable logistic regression analysis was conducted to determine the risk factors for postoperative candidemia. RESULTS: Thirty-five candidemia cases were identified and matched to 70 control cases. The incidence of candidemia was 6.3 episodes per 1000 admissions. The median age for candidemia cases was 4 months. The attributable mortality was 28.5%. The predominant (54%) pathogens isolated were non- albicans Candida species, of which C. parapsilosis isolates demonstrated high resistance to fluconazole (70%). Independent risk factors associated with candidemia included cumulative antibiotic exposure for ≥4 days [OR: -4.3; 95% confidence interval (CI): 1.3-14.6; P = 0.02], the need for total parenteral nutrition or peritoneal dialysis (OR: -6.1; 95% CI: 2-18.8; P = 0.001), male sex (OR: 6.2; 95% CI: 1.9-20.3; P = 0.002) and delayed sternal closure≥2 days (OR: -3.2; 95% CI: 1-11.2; P = 0.05). CONCLUSIONS: Postoperative candidemia in children with CHD is an uncommon but severe complication. Our study revealed an unexpectedly high frequency of fluconazole-resistant C. parapsilosis as the main cause of non- albicans candidemia. In addition to confirming previously recognized risk factors, our results reveal new potential risk factors such as delayed sternal closure and male sex.

Monitoring of Enterovirus D68 Outbreak in Israel by a Parallel Clinical and Wastewater Based Surveillance.

Enterovirus D68 (EVD68) was recently identified as an important cause of respiratory illness and acute flaccid myelitis (AFM), mostly in children. Here, we examined 472 pediatric patients diagnosed with severe respiratory illness and screened for EVD68 between April and October 2021. In parallel, samples collected from a wastewater treatment plant (WWTP) covering the residential area of the hospitalized patients were also tested for EVD68. Of the 472 clinical samples evaluated, 33 (7%) patients were positive for EVD68 RNA. All wastewater samples were positive for EVD68, with varying viral genome copy loads. Calculated EVD68 genome copies increased from the end of May until July 2021 and dramatically decreased at the beginning of August. A similar trend was observed in both clinical and wastewater samples during the period tested. Sequence analysis of EVD68-positive samples indicated that all samples originated from the same branch of subclade B3. This study is the first to use wastewater-based epidemiology (WBE) to monitor EVD68 dynamics by quantitative detection and shows a clear correlation with clinically diagnosed cases. These findings highlight the potential of WBE as an important tool for continuous surveillance of EVD68 and other enteroviruses.

Rapid Detection of Carbapenemase-producing Enterobacteriaceae From Blood Culture Bottles of Known CPE Carriers: Real-world Experience.

We used a rapid antigen test for the detection of carbapenemases directly from positive blood culture bottles of pediatric hemato-oncologic patients, known carriers of carbapenemase-producing enterobacteriaceae. Resistance mechanism was detected within 15 minutes of observing Gram-negative bacilli from a positive bottle, leading to treatment modification. This simple-to-use, inexpensive assay shortens the interval between empiric to tailored antimicrobial therapy.

The "combined team" transition clinic model in endocrinology results in high adherence rates and patient satisfaction.

Background A structured transition process for young adults with chronic medical conditions from pediatric to adult clinics is strongly promoted. However, the most appropriate transition model has not yet been determined. This study evaluated the effect of a "combined team" Endocrinology Transition Clinic model, including a joint meeting with the patient and pediatric and adult endocrinologists, regarding medical treatment, adherence to follow-up and patient satisfaction with the process. Methods Clinical and demographic data of patients admitted to the Endocrinology Transition Clinic were collected. The clinical impact of the transition meeting was evaluated based on treatment modifications and patient adherence to follow-up. Patient satisfaction was evaluated using a questionnaire. Results From September 2014 through November 2018, 107 patients attended the Endocrinology Transition Clinic, 85.0% were females, mean age 19.7 ± 2.2 years (range 16-29), 97.2% were unmarried. The most common endocrine disorders were obesity (41.1%), Hashimoto's thyroiditis (41.1%) and ovarian hyperandrogenism (38.3%). The Transition Clinic visit modified treatment and/or evaluation for 48 (44.8%) patients. Adherence to follow-up in the adult clinic was 82.9% and was not associated with gender (p = 0.366), ethnicity (p = 0.725), age at transition (p = 0.479) or obesity (p = 0.375). Overall satisfaction reported by 65/85 patients was high (86.8%), although higher among patients who were adherent to follow-up (89.4% vs. 65.6%, p = 0.006). Conclusions The "combined team" transition model in endocrinology requires relatively few resources and has considerable clinical impact, high adherence to follow-up and high patient satisfaction rate. Implementing this model at the interface of pediatric and adult endocrinology units, and possibly in other medical fields, is feasible and efficient.
