Consensus document of the Spanish Society of Paediatric Infectious Diseases (SEIP) and the Spanish Society of Paediatric Intensive Care (SECIP) for the diagnosis and treatment of central venous catheter-related infections in paediatric care.

Intravascular devices are essential for the diagnostic and therapeutic approach to multiple diseases in paediatrics, and central venous catheters (CVCs) are especially important. One of the most frequent complications is the infection of these devices, which is associated with a high morbidity and mortality. These infections are highly complex, requiring the use of substantial resources, both for their diagnosis and treatment, and affect vulnerable paediatric patients admitted to high-complexity units more frequently. There is less evidence on their management in paediatric patients compared to adults, and no consensus documents on the subject have been published in Spain. The objective of this document, developed jointly by the Spanish Society of Paediatric Infectious Diseases (SEIP) and the Spanish Society of Paediatric Intensive Care (SECIP), is to provide consensus recommendations based on the greatest degree of evidence available to optimize the diagnosis and treatment of catheter-related bloodstream infections (CRBSIs). This document focuses on non-neonatal paediatric patients with CRBSIs and does not address the prevention of these infections.

"Catheter replacement in catheter-associated urinary tract infection: current state of evidence ".

PURPOSE: Catheter associated urinary tract infection (CAUTI) is the most common healthcare associated infection. A significant knowledge gap exists regarding the necessity of catheter replacement as part of CAUTI treatment. Current guidelines recommend replacement for faster recovery and to prevent recurrences, but adherence is low. In this systematic review, we aimed to assess the available evidence regarding catheter replacement for CAUTI. MATERIALS AND METHODS: Eligible studies investigated the effect of catheter replacement in CAUTI on clinical outcomes and/or recurrence rates, irrespective of catheter type or setting. We searched electronic literature databases from inception to October 15th, 2023. Information was extracted regarding setting, eligibility criteria, definition of CAUTI, timing of replacement, and outcomes. RESULTS: Of the 257 identified studies, four were considered relevant and included. Two were randomized controlled trials (RCT) and two were observational studies. One RCT showed higher rates of clinical recovery and lower recurrence rates in the replacement group, while results of the other RCT favoured retainment, with a lower recurrence rate in the retainment group, although longer antimicrobial treatment in this group. Two observational studies were inconclusive. CONCLUSIONS: Current guidelines rely heavily on recommendations from a single study, emphasizing the need for further research. The burden of catheter replacement, including patient discomfort and resource impact, warrants careful consideration. A randomized trial is essential to provide more evidence on the effect of catheter replacement on clinical outcomes including CAUTI recurrence.

Salvage strategy for long-term central venous catheter-associated Staphylococcus aureus infections in children: a multi-centre retrospective study in France.

OBJECTIVES: Catheter removal is recommended in adults with Staphylococcus aureus central-line-associated bloodstream infection (CLABSI) but is controversial in children with long-term central venous catheters (LTCVC). We evaluated the occurrence of catheter salvage strategy (CSS) in children with S. aureus LTCVC-associated CLABSI and assessed determinants of CSS failure. METHODS: We retrospectively included children (<18 years) with an LTCVC and hospitalized with S. aureus CLABSI in eight French tertiary-care hospitals (2010-2018). CSS was defined as an LTCVC left in place ≥72 h after initiating empiric antibiotic treatment for suspected bacteraemia. Characteristics of patients were reviewed, and multi-variable logistic regression was performed to identify factors associated with CSS failure (i.e., persistence, recurrence or complications of bacteraemia). RESULTS: We included 273 episodes of S. aureus LTCVC-associated CLABSI. CSS was chosen in 194 out of 273 (71%) cases and failed in 74 of them (38%). The main type of CSS failure was the persistence of bacteraemia (39 of 74 cases, 53%). Factors independently associated with CSS failure were: history of catheter infection (adjusted odds ratio (aOR) 3.18, 95% confidence interval (CI) 1.38-7.36), CLABSI occurring on an implantable venous access device (aOR 7.61, 95% CI 1.98-29.20) when compared with tunnelled-cuffed CVC, polymicrobial CLABSI (aOR 3.45, 95% CI 1.25-9.50), and severe sepsis at the initial stage of infection (aOR 4.46, 95% CI 1.18-16.82). CONCLUSIONS: CSS was frequently chosen in children with S. aureus LTCVC-associated CLABSI, and failure occurred in one-third of cases. The identified risk factors may help clinicians identify children at risk for CSS failure.

Teaching-Learning Programs to Prevent and Control Infections Related to Long-Term Central Venous Access Device in Cancer Patients: A Systematic Review.

OBJECTIVES: To evaluate the effectiveness of teaching-learning programs for cancer patients and/or their caregivers or family in preventing and controlling infections associated with long-term central venous access devices. DATA SOURCES: This systematic review used the CINAHL, Cochrane Library, EMBASE, LILACS, and MEDLINE via PubMed portal, Scopus, and Web of Science. Google Scholar was used for the gray literature search. The included studies were analyzed, and the obtained data were qualitatively synthesized. The risk of bias was assessed using Cochrane tools: RoB 2 and ROBINS-I. The certainty of the evidence was evaluated using the GRADE. The review protocol was registered in PROSPERO (CRD42021267530). CONCLUSION: The teaching-learning programs were implemented through theoretical-practical and theoretical dimensions in five and two studies, respectively. The risk of bias in the studies was low, moderate, severe, and high in one, three, two, and one of them, respectively. The certainty was very low. Teaching-learning programs on central venous access devices care for cancer patients and/or their caregivers or families could be effective in reducing infection rates. IMPLICATIONS FOR NURSING PRACTICE: This systematic review addressed the teaching-learning programs for preventing and controlling infections associated with long-term central venous access devices. We identified that the most programs were effective in reducing the infection rates. The results may influence the clinical practice of oncology nurses, and consequently, the educational strategies and methods provided not only to these patients but for caregivers and families.

Life on the line - Incidence and management of central venous catheter complications in intestinal failure.

BACKGROUND & AIMS: Loss of venous access is threatening for patients with intestinal failure (IF) under long-term parenteral nutrition (PN). We aimed to identify the incidence of central venous catheter (CVC) complications, compare different devices, and analyze interventional recanalizing procedures to restore the patency of occluded CVCs. METHODS: For this retrospective cohort study, patient data from a prospective IF database spanning 16 years was analyzed at a tertiary referral center. Catheter dwell times (CDTs) were distinguished by Kaplan-Meier survival analysis and subgroup analyses were performed for different CVC types (tunneled/port catheters). Specific complications (occlusion, catheter-related infection (CRI), displacement, and material defect) were analyzed. Explantation rates and CDTs were compared. RESULTS: Overall, 193 CVCs in 77 patients with IF under PN could be enrolled (62.524 "CVC-days"). Broviac type "B" was found to be significantly superior to type "A" regarding occlusion, CRI, and material defects (log-rank test: p = 0.05; p = 0.026; p = 0.005 respectively). Port catheters were displaying the highest incidence of CRI (2.13 events/1000 catheter days). Interventional catheter recanalization was performed 91 times and significantly increased the CDT from a median of 131 days (IQR: 62; 258) to 389 days (IQR: 262; 731) (Mann-Whitney-U-test: p= <0.001) without increasing complications. CONCLUSIONS: Different complication rates and CDT were seen depending on CVC type. Tunneled catheters were significantly superior concerning CRI. Interventional catheter recanalization is a viable alternative to fibrinolytics to restore CVC patency, but long-term patency data is scarce.

A meta-analysis of risk factors for a Dacron-cuffed catheter related infection in hemodialysis.

OBJECTIVE: To provide theoretical basis for prevention of a Dacron-cuffed catheter related infection (CRI), the risk factors of CRI in hemodialysis patients were systematically evaluated. METHODS: Eight databases, including PubMed, Cochrane library, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Database (CBM), Wanfang Database and Chinese Scientific Journal Database (VIP), were searched to screen out literatures related to the risk factors of long-term indwelling a Dacron-cuffed CRI in hemodialysis. Meta-analysis of risk factors for a Dacron-cuffed CRI in hemodialysis and publication bias test were performed using RevMan 5.4 software. RESULTS: After screening, 13 literatures involving a Dacron-cuffed CRI were included, with a total of 625 patients, and the infection rate was 11.7%. The combined OR value and 95% confidence interval (CI) of all factors were: Combined with Diabetes (1.94, 1.51 ~ 2.50), Hb (1.82, 1.35 ~ 2.44), age (2.38, 1.06 ~ 5.34), catheter indwelling time (1.79, 1.21 ~ 2.66), serum albumin (2.26, 1.25 ~ 4.08), catheter indwelling site (3.29, 1.74 ~ 6.23) and the number of tube placement (5.40, 2.65 ~ 11.02). CONCLUSIONS: The main risk factors for a Dacron-cuffed CRI in hemodialysis were combined with diabetes, hemoglobin level, age, catheter indwelling time, serum albumin level, femoral vein catheter indwelling and catheterization times. In other words, hemodialysis patients are at higher risk of CRI if they have diabetes, or if they have a lower hemoglobin level, or if they are older, or if they have a longer duration of catheterization, or if they have a lower serum albumin level, or if they have a femoral vein catheter, or if they have more catheters.

Risk factors and prediction model construction for peripherally inserted central catheter-related infections.

Objective: To establish a predictive modeling for the risk of bloodstream infection associated with peripherally inserted central catheter (PICC). Methods: Patients receiving PICC treatment in Shenzhen People's Hospital from June 2020 to December 2020 were retrospectively enrolled and divided into the infection group and the non-infection group according to the presence and absence of PICC-related infections. Then, relevant clinical information of patients was collected and the predictors of PICC-related infection were screened by the least absolute shrinkage and selection operator regression (LASSO) model. Besides, multivariate logistic regression was used to analyze the influencing factors of PICC-related infection, A nomogram was constructed based on the results of the multivariate analysis. Ultimately, a receiver operating characteristic (ROC) curve was plotted to analyze the application value of influencing factors to predict PICC-related infections. Results: A total of 505 patients were included, including 75 patients with PICC-related infections (14.85%). The main pathogen was gram-positive cocci. The predictors screened by LASSO included age >60 years, catheter movement, catheter maintenance cycle, insertion technique, immune function, complications, and body temperature ≥37.2 °C before PICC placement. Multivariate logistic regression analysis showed that independent risk factors of infections related to PICC included age >60 years [odds ratio (OR) = 1.722; 95% confidence interval (CI) = 1.312-3.579; P = 0.006], catheter movement (OR = 1.313; 95% CI = 1.119-3.240; P = 0.014), catheter maintenance cycle >7 days (OR = 2.199; 95% CI = 1.677-4.653; P = 0.000), direct insertion (OR = 1.036; 95% CI = 1.019-2.743; P = 0.000), poor immune function (OR = 2.322; 95% CI = 2.012-4.579; P = 0.000), complications (OR = 1.611; 95% CI = 1.133-3.454; P = 0.019), and body temperature ≥37.2 °C before PICC placement (OR = 1.713; 95% CI = 1.172-3.654; P = 0.012). Besides, the area under the ROC curve was 0.889. Conclusion: PICC-related infections are associated with factors such as age >60 years, catheter movement, catheter maintenance cycle, insertion technique, immune function, complications, and body temperature ≥37.2 °C before PICC placement. Additionally, the LASSO model is moderately predictive for predicting the occurrence of PICC-related infections.

Surgical outcomes of very-early-onset ulcerative colitis: retrospective comparative study with older pediatric patients.

PURPOSE: The study compares the surgical outcomes of very-early-onset ulcerative colitis (VEO-UC), which is a rare disease diagnosed in pediatric patients < 6 years, with those of older pediatric patients with ulcerative colitis (UC). METHODS: A retrospective observational study of 57 pediatric patients with UC was conducted at a single center. The study compared surgical complications and postoperative growth between the two groups. RESULTS: Out of the 57 patients, 6 had VEO-UC, and 5 of them underwent total colectomy. Compared with the surgical cases of older patients with UC (n = 6), the rate of postoperative complications in patients with VEO-UC (n = 5) was not significantly different, except for high-output ileostomy (80% vs. 0% at 3 weeks postoperatively, p = 0.02). The rate of postoperative central venous catheter (CVC) placement at > 90 days was higher in patients with VEO-UC (100% vs. 17%, p = 0.02). The median change in the Z-score of height before and 2 years after colectomy was not significantly different between VEO-UC and older patients (1.1 vs. 0.3, p = 0.13). CONCLUSION: With regard to complications and outcomes, total colectomy for VEO-UC patients and that for older pediatric UC patients is comparable. However, high-output ileostomy and the long duration of CVC placement may pose management challenges.

The accuracy of fully-automated algorithms for the surveillance of central venous catheter-related bloodstream infection in hospitalised patients.

BACKGROUND: Continuous surveillance for healthcare-associated infections such as central venous catheter-related bloodstream infections (CVC-BSI) is crucial for prevention. However, traditional surveillance methods are resource-intensive and prone to bias. This study aimed to develop and validate fully-automated surveillance algorithms for CVC-BSI. METHODS: Two algorithms were developed using electronic health record data from 1000 admissions with a positive blood culture (BCx) at Karolinska University Hospital from 2017: (1) Combining microbiological findings in BCx and CVC cultures with BSI symptoms; (2) Only using microbiological findings. These algorithms were validated in 5170 potential CVC-BSI-episodes from all admissions in 2018-2019, and results extrapolated to all potential CVC-BSI-episodes within this period (n = 181,354). The reference standard was manual record review according to ECDC's definition of microbiologically confirmed CVC-BSI (CRI3-CVC). RESULTS: In the potential CVC-BSI-episodes, 51 fulfilled ECDC's definition and the algorithms identified 47 and 49 episodes as CVC-BSI, respectively. Both algorithms performed well in assessing CVC-BSI. Overall, algorithm 2 performed slightly better with in the total period a sensitivity of 0.880 (95%-CI 0.783-0.959), specificity of 1.000 (95%-CI 0.999-1.000), PPV of 0.918 (95%-CI 0.833-0.981) and NPV of 1.000 (95%-CI 0.999-1.000). Incidence according to the reference and algorithm 2 was 0.33 and 0.31 per 1000 in-patient hospital-days, respectively. CONCLUSIONS: Both fully-automated surveillance algorithms for CVC-BSI performed well and could effectively replace manual surveillance. The simpler algorithm, using only microbiology data, is suitable when BCx testing adheres to recommendations, otherwise the algorithm using symptom data might be required. Further validation in other settings is necessary to assess the algorithms' generalisability.

Sodium bicarbonate is a potential alternative to classic heparin as a lock solution for non-tunneled dialysis catheters: a result from the prospective randomized BicarbLock trial.

OBJECTIVE: Temporary vascular access is mandatory for acute hemodialysis. Heparin lock solution is the standard of care worldwide. Many lock solutions were studied in terms of thrombosis and catheter-related infection prevention, but none replaced heparin as a standard measure. Our main aim is to investigate the effectiveness of sodium bicarbonate (NaHCO3), a ubiquitous and cheap option as a catheter lock solution, in comparison with traditionally used heparin in non-tunneled hemodialysis catheters. METHODS: We conducted our prospective study between March 2021 and March 2022. Our study included 441 patients > 18 years old who needed either femoral or jugular non-tunneled dialysis catheters. Patients were assigned to either heparin (5000 IU/ml) or 8.4% sodium bicarbonate on a consecutive basis. Basic characteristics and information regarding catheters, dialysis sessions, and complications were recorded. We divided patients according to the catheter insertion site as well as the lock solution. RESULTS: We analyzed 426 patients divided into four groups: jugular heparin (n = 113), jugular bicarbonate (n = 113), femoral heparin (n = 113), and femoral bicarbonate (n = 100). Basal characteristics were similar for all groups. The mean time to last effective dialysis in our institution was 10.7 ± 12.1 days for heparin vs 11.5 ± 10.8 days for the bicarbonate group. 25 (5.9%) patients had some kind of blood flow problems (13 in the heparin and 12 in the bicarbonate group). There was no significant difference in terms of catheter malfunction among groups (p = 0.50). Out of these 25 cases, only 12 (7 in heparin and 5 in the bicarbonate arm) had catheter dysfunction (p = 0.386). Sixty-four patients (28%) with jugular catheters were discharged with patent catheters and continued their dialysis in other facilities. CONCLUSION: Sodium bicarbonate is as effective as classic unfractionated heparin in preventing catheter lumen thrombosis with a comparable incidence of catheter-related complications. Furthermore, it is a cost-effective option that can be used confidently, especially when heparin is contraindicated. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04772209 (26.02.2021).

Central venous catheter (CVC) salvage in case of central line-associated bloodstream infection (CLABSI): A monocentric prospective study in patients on long-term home parenteral nutrition (HPN).

BACKGROUND & AIMS: CLABSI is a major complication in HPN and frequently leads to central venous catheter (CVC) removal. We developed a salvaging attitude in long term HPN patients due to the necessity of venous preservation. The main objective of this study is to determine the prognosis of CLABSI. METHODS: We followed-up for three months, in an approved HPN centre, a cohort of 250 adult patients receiving HPN with CLABSI from 2018 to 2020. CLABSI was defined by a blood culture growth differential [peripheral blood] - [CVC blood] ≥ 2h. A therapeutic approach to conserve CVC was established according to the department's protocol. The primary endpoint was conservation of CVC with negative CVC and peripheral blood cultures at 3 months without complications. RESULTS: Data from 30 CLABSIs were collected for 22 HPN patients. The incidence rate of CLABSIs was 0.28 infections/1000 catheter days. Sixteen CVCs were removed immediately, with causes due to the type of germ (staphylococcus aureus: n = 6, candida parapsilosis: n = 4, klebsiella: n = 2), chronic colonization (n = 4) or initial complications (n = 4). Among the 14 non-removed CVC, 11 were maintained at 3 months with blood cultures on CVC and peripheral negative for 9 (80%) of them. 3 CVC were removed during the 3 months follow-up (non-CVC-related sepsis n = 2, and resistant pseudomonas aeruginosa n = 1). CONCLUSION: The incidence rate of CLABSIs in an expert HPN centre remains low. In case of CLABSIs, according to specific protocol, approximately 50% of CVC were removed immediately (essentially due to bacteriological characteristics). In case of CLABSIs and without initial complication, 80% of CVCs can be maintained at 3 months. These results justify a conservative attitude according to standardized protocol.

Short-Course Versus Prolonged-Course Antimicrobial Therapy in Adults With Catheter-Related Septic Thrombosis: A Propensity-Weighted Retrospective Study.

Background: Optimal duration of antimicrobial therapy (AT) for catheter-related septic deep venous thrombosis (DVT) is unknown. We aimed to compare the outcomes of patients receiving short-course AT (≤21 days) versus prolonged-course AT (>21 days). Methods: This was a monocentric retrospective study comparing adults with catheter-related septic DVT from 2015 to 2020 treated with short- or prolonged-course AT. A propensity score-weighted analysis was used to mitigate potential bias. The primary outcome was a composite of all-cause mortality or recurrent bloodstream infection 30 days after AT discontinuation. Results: Of 172 patients with catheter-related septic DVT, 104 were treated with prolonged-course AT and 68 with short-course AT. In the propensity score analysis, we found no significant difference in 30-day all-cause mortality or relapse between the 2 groups (inverse probability of treatment weighted hazard ratio [wHR], 2.16 [95% confidence interval {CI}, .68-6.88]; P = .192). No differences in 90-day all-cause mortality and 90-day relapse were observed between the treatment groups (wHR, 1.01 [95% CI, .49-2.05], P = .987 and 1.13 [95% CI, .08-15.62], P = .928, respectively). Conclusions: A 21-day AT could be an effective and safe option to treat catheter-related septic DVT. Further randomized studies are needed to establish the optimal duration of AT for patients with catheter-related septic DVT.

Evaluating the Potential of a New Low-Profile Urinary Catheter in Preventing Catheter-Associated Urinary Tract Infections: A Prospective Randomized Blinded Clinical Trial.

Aim: To investigate the efficacy of a new low-profile catheter on incidence of the catheter-associated urinary tract infections (CAUTI) in comatose patients admitted to the intensive care unit. Background: Catheter-induced urothelial injury is a key component in the development of urinary tract infections in catheterized patients. Methods: In this prospective randomized blinded clinical trial, 80 patients requiring indwelling urinary catheterization were equally randomized to either the standard Foley catheter (control) or the low-profile catheter (experimental) group. The signs of urinary tract infection for comatose patients were considered (ie, ≥105 of colony-forming unit/milliliter of urine, hematuria, serum leukocytes, and body temperature) and recorded at baseline and on days 3 and 5 after catheterization. The analysis of covariance was applied by the SPSS-20 software at a 95% confidence level. Results: An increasing proportion of patients with elevated urinary colony counts were seen in the Foley catheter group compared with the low-profile catheter group (12.5% vs 5%). However, there were no between-group differences in the urinary colony counts and body temperature after controlling for antibiotic doses and fluid intake. Patients in the low-profile catheter group had significantly lower rates of hematuria and serum leukocytes than those in the Foley catheter group. Conclusion: A newly designed low-profile urinary catheter has demonstrated a trend toward reducing the incidence of CAUTI in patients with indwelling urinary catheters. Further studies with larger sample sizes and follow-up are needed to confirm the benefits.

Microbiota of long-term indwelling hemodialysis catheters during renal transplantation perioperative period: a cross-sectional metagenomic microbial community analysis.

Background: Catheter-related infection (CRI) is a major complication in patients undergoing hemodialysis. The lack of high-throughput research on catheter-related microbiota makes it difficult to predict the occurrence of CRI. Thus, this study aimed to delineate the microbial structure and diversity landscape of hemodialysis catheter tips among patients during the perioperative period of kidney transplantation (KTx) and provide insights into predicting the occurrence of CRI.Methods: Forty patients at the Department of Transplantation undergoing hemodialysis catheter removal were prospectively included. Samples, including catheter tip, catheter outlet skin swab, catheter blood, peripheral blood, oropharynx swab, and midstream urine, from the separate pre- and post-KTx groups were collected and analyzed using metagenomic next-generation sequencing (mNGS). All the catheter tips and blood samples were cultured conventionally.Results: The positive detection rates for bacteria using mNGS and traditional culture were 97.09% (200/206) and 2.65% (3/113), respectively. Low antibiotic-sensitivity biofilms with colonized bacteria were detected at the catheter tip. In asymptomatic patients, no statistically significant difference was observed in the catheter tip microbial composition and diversity between the pre- and post-KTx group. The catheter tip microbial composition and diversity were associated with fasting blood glucose levels. Microorganisms at the catheter tip most likely originated from catheter outlet skin and peripheral blood.Conclusions: The long-term colonization microbiota at the catheter tip is in a relatively stable state and is not readily influenced by KTx. It does not act as the source of infection in all CRIs, but could reflect hematogenous infection to some extent.

Comparison of complications after closure of totally implantable venous access devices with non-absorbable suture and n-butyl-2-cyanoacrylate (NBCA) skin adhesive: Propensity score matching analysis.

PURPOSE: This study aimed to compare the complication rates of non-absorbable suture (NAS) and n-butyl-2-cyanoacrylate (NBCA) skin adhesive for skin closure during totally implantable venous access devices (TIVADs) implantation. METHODS: Between March 2020 and February 2021, 586 consecutive patients who underwent TIVAD implantation were retrospectively analyzed. Two groups of patients suture with NAS (n = 299) or NBCA (n = 287) were followed up for 18 months to compare the occurrence of infection, thrombosis, and non-thrombotic malfunction. A total of 364 cases were extracted using propensity score matching in a 1:1 ratio. Mean TIVADs maintenance days were analyzed using Kaplan-Meier survival analysis. RESULTS: Nineteen cases of complications occurred (0.294/1000 catheter-days) in the NAS group and 17 cases (0.210/1000 catheter-days) in the NBCA group. The difference in the complication rates between the two groups was not statistically significant (p = 0.725) after propensity score matching. Mean TIVADs maintenance days were 627.3 days in NAS group and 697.6 days in NBCA group. There was no statistically significant difference in the number of TIVADs maintenance days between the two groups (p = 0.081). CONCLUSION: In TIVADs implantation, skin closure using NBCA showed no difference in the occurrence of infectious complications compared with conventional non-absorbable skin suture.

A Rare Presentation of Perivalvular Abscess and Infective Valve Endocarditis as Multiple Cerebral Septic Emboli Mimicking Ischemic Stroke.

The perivalvular cardiac abscess is a severe condition associated with infective endocarditis, leading to significant morbidity and mortality if not diagnosed and managed promptly. Neurological complications, particularly stroke, can occur due to embolic events resulting from cardiac abscesses. A 63-year-old female with end-stage renal disease and multiple comorbidities presented with altered mental status. Imaging revealed acute ischemic infarcts in the frontotemporal lobes, suggesting the embolic phenomenon. Blood cultures grew Enterococcus faecalis, and an echocardiogram showed severe aortic valve destruction with perivalvular abscess. Cardiac abscesses can cause severe complications, including tissue destruction, valve damage, and embolic events. Echocardiography is crucial for diagnosis, detecting vegetation, and assessing associated complications. Transthoracic echocardiography is reliable but has limitations, whereas transesophageal echocardiography is highly sensitive. Prompt antibiotic therapy and surgical intervention are crucial for treatment. Early initiation of appropriate antibiotic therapy and surgical intervention is crucial for positive outcomes. The choice of treatment should be individualized based on the patient's specific condition and the medical team's expertise.

Granuloma formation after repeated episodes of peritoneal dialysis catheter-related infection, a case report.

BACKGROUND: Peritoneal catheter related infection is one of the main complications and the major cause of technical failure of peritoneal dialysis (PD) treatment. However, PD catheter tunnel infection can be difficult to diagnosis and resolve. We presented a rare case in which a granuloma formation after repeated episodes of peritoneal dialysis catheter-related infection. CASE PRESENTATION: A 53-year-old female patient with kidney failure due to chronic glomerulonephritis treated with peritoneal dialysis for 7 years. The patient had repeated exit-site and tunnel inflammation, and repeated suboptimal courses of antibiotics. She switched to hemodialysis after 6 years in a local hospital without the peritoneal dialysis catheter being removed. The patient complained of an abdominal wall mass that lasted for several months. She was admitted to the Department of surgery to undergo mass resection. The resected tissue of the abdominal wall mass was sent for pathological examination. The result showed foreign body granuloma with necrosis and abscess formation. After the surgery, the infection did not recur. CONCLUSIONS: The following key points can be learned from this case: 1. It is important to strengthen patient follow-up. 2.The PD catheter should be removed as early as possible in patients who do not need long-term PD, especially in patients with a history of exit-site and tunnel infections. 3. For patients presenting abnormal subcutaneous mass, attention should be paid to the possibility of the granuloma formation of infected Dacron cuffs of the PD catheter. If catheter infection occurs repeatedly, catheter removal and debridement should be considered.

Characteristics and Treatment of Gordonia spp. Bacteremia, France.

Systemic Gordonia spp. infections are rare and occur mostly among immunocompromised patients. We analyzed 10 cases of Gordonia bacteremia diagnosed in 3 tertiary care centers in France to assess risk factors, treatment, and clinical outcomes. Most patients were cured within 10 days by using ß-lactam antimicrobial therapy and removing central catheters.

Impact of the insertion site of central venous catheters on central venous catheter-related bloodstream infections in patients with cancer: results from a large prospective registry.

PURPOSE: Overall, insertion of central venous catheter (CVC) into femoral veins (FV) has been shown to be associated with a higher risk of infection compared with subclavian and internal jugular (IJV/SCV) CVC, but no data are available on the impact of the FV insertion site on the CVC-related bloodstream infections (CRBSI) risk in patients with cancer. The objective of the study is to compare CRBSI rates and incidences of FV with those of internal jugular and subclavian vein (IJV/SCV CVC) as observed in the prospective SECRECY registry. METHODS: SECRECY is an ongoing observational, prospective, clinical CRBSI registry active in six departments of hematology/oncology in Germany. Each case of FV CVC was matched at a ratio of 1:1 to a case with IJV/SCV CVC. The propensity score was estimated using a multivariable logistic regression model adjusting for age, sex, cancer type, and duration of indwelling catheter. RESULTS: Of 4268 CVCs included in this analysis, 52 (1.2%) were inserted into the FV and 4216 (98.8%) into the IJV/SCV. 52 cases of FV CVC were matched with 52 IJV/SCV CVC. There was no significant difference in the CRBSI rate (3.8% vs. 9.6%), the CRBSI incidence (5.7 vs. 14.2/1000 CVC days), and the median CVC time (5.5 vs. 5 days) between the FV and the IJV/SCV group. CONCLUSION: Based on this data, inserting FV CVCs in patients with cancer does, at least in the short-term, not appear to be associated with an increased risk of CRBSI as compared to IJV/SCV CVC.

Compliance assessment regarding the PVC management on normal wards of a university hospital.

Objective: The risk of peripheral venous catheter (PVC) infections in inpatients is often underestimated, even if it is lower than that for central venous catheters. Guidelines for the prevention of PVC-associated infections describe the evidence-based management of PVCs. The aims of this study were the development of standardized methods for compliance assessment regarding PVC management and the evaluation of self-reported knowledge and implementations among healthcare providers regarding PVC care. Method: We developed a checklist based on the recommendation of the Commission of Hospital Hygiene and Infection Prevention at the Robert Koch Institute (KRINKO) Berlin for the standardized evaluation of PVC management. The following parameters were collected and evaluated: condition of the puncture site, condition of the bandage, presence of an extension set, presence of a plug, and documentation. The checklist was applied in 14 normal wards in 2019. After feedback of the ward staff on the results, it was applied again in 2020 in the same wards. For retrospective data analysis, we used a newly developed PVC-quality index. After the second evaluation in 2020, we carried out an anonymous survey among the healthcare providers. Results: The evaluation of 627 indwelling PVCs showed a significant increase in compliance related to the presence of an extension set (p=0.049) and documentation (p<0.001) in the 2nd year. The quality index increased in 12 out of 14 wards. The participants of the survey were aware of the in-house standard "Prevention of vascular catheter-associated infections", with a mean score of 4.98 on a Likert scale (1=not aware, 7=completely aware). The main barrier to implementation of the preventive measures was the time factor. Survey participants were more aware of PVC placement than PVC care. Conclusion: The PVC quality index is a valuable tool for the assessment of compliance regarding PVC management in daily practice. Feedback from the ward staff on the results of compliance assessment improves PVC management, but the outcome is very heterogeneous.
