Background: Standard 24-h antibiotic prophylaxis (AP) is widely employed to minimize the risk of infection complications (ICs) within 30 days following a radical cystectomy (RC). However, a considerable variety of prophylaxis protocols do not prevent a high ICs rate after surgery (37–67%). Therefore, antibiotic's type and its duration are still controversial for AP.(Objective: To compare standard 24-h AP with a prolonged 120-h regimen in a multicenter randomized clinical trial. Methods: Patients were randomized in a 1:1 ratio to standard 24-h AP regimen (Group A) versus the prolonged meropenem AP 120-h (Group B). The primary endpoint was an event rate defined as the frequency of ICs within 30 days. The secondary endpoint were biomarker's analysis and antibiotic re-administration rate (ArAR). Results: A total of 92 patients were enrolled. The Clavien-Dindo complications rate did not differ between the groups (p = 0.065), however the overall complication rate was higher in Group A (63.0% vs. 34.8%, p = 0.007). The infection complication rate was 2.75 times higher in the standard antibiotic prophylaxis group: 47.8% compared to 17.4% cases in Group B (p = 0.002). The new prolonged antibiotic regimen decreased the risk of ICs (OR 0.23; 95% CI 0.08–.598; p = 0.003). The event-free survival for ICs of clinical interest in group A was 7.00 days and in group B was 9.00 days (HR = 0.447; 0.191–1.050, p = 0.065). The ArAR was higher in Group A -47.8%, while in Group B it was only in 17.4% of the cases. The incidence of bacteriuria before RC was the same between groups (p = 0.666), however, after stent removal the risk of a positive culture was lower in group B (RR = 0.64; 95% CI 0.37–1.08; p = 0.05). Conclusions: The administration AP over 120-h appears to be safe and feasible, demonstrating a reduction in the total number of complications and ArAR.

Abstract Objective To identify risk factors for infection complications in patients with gastrointestinal diffuse large B-cell lymphoma (GI-DLBCL) and nodal DLBCL (N-DLBCL) during treatment, respectively. Methods Total 51 GI-DLBCL patients and 80 N-DLBCL patients were included after retrieving clinical data from a single medical center in the past ten years. Logistic regression analysis was utilized to analyze patients’ data, including baseline demographics, treatments and laboratory values, to determine independent risk factors of infection in these patients. Results Total 28 of 51 patients (54.9%) in the GI-DLBCL group and 52 of 80 patients (65%) in the N-DLBCL group were observed infection events during treatment. A multivariate logistic regression model revealed that Ann-arbor stage IV (P = 0.034; odds ratio [OR]: 10.635; 95% confidence interval [CI]: 1.152-142.712), extra-nodal lesions ≥ 2 (P = 0.041; OR: 23.116; 95%CI: 1.144-466.949) and high serum lactate dehydrogenase (LDH) at the time of diagnosis (LDH > 252U/L; P = 0.033; OR: 6.058; 95%CI: 1.159–31.659) were independent risk factors for the development of infection in patients with GI-DLBCL after systemic treatment. In the N-DLBCL group, high serum C-reactive protein (CRP) (P = 0.027; OR: 1.104; 95%CI: 1.011–1.204) and a low platelet count (P = 0.041; OR: 0.991; 95%CI: 0.982-1.000) at routine blood tests just before infection occurred were identified as significant risk factors related to infection events during treatment. Conclusions Discordant independent risk factors induced infection may be present during the treatment in patients with GI-DLBCL and N-DLBCL. Close monitoring these risk factors is likely an effective strategy to prevent microbial infections in these patients.

A retrospective cohort study was conducted to assess differences in efficacy and tolerability between a busulfan AUC target of 16.4 mg × Hr/L per day (FluBu4K) and a conventional RIC regimen (FluBu2). Adult patients with a diagnosis of AML or MDS who received fludarabine + busulfan conditioning with or without antithymocyte globulin between 2015 and 2018 were included. The primary outcome was relapse free survival. Overall, 74 patients received conditioning with either FluBu4K or FluBu2. At 18 months, relapse-free survival was not significantly different, at 63.9% with FluBu4k compared to 57.5% with FluBu2 (p = 0.49). There was a statistically significant difference in the cumulative incidence of relapse at 18 months in favor of the FluBu4K regimen, at 12.0% vs 32.5% (p = 0.047). The results of this study indicate that for select patients, there may be benefit in choosing targeted FluBu4K over FluBu2. Adverse effects other than mucositis were not significantly different.

The number of patients with end-stage renal disease (ESRD) treated with hemodialysis (HD) increases annually globally. One of the main factors determining the quality of their lives is the type of vascular access used. Tunnel catheters have entered the medical practice since 1987. Regardless of the recommendations for their use in up to 10% of hemodialysis patients, their relative share has risen in the last two decades two to three times in the countries of Europe, and in the USA and Canada, they represent over 40% of the access for hemodialysis treatment. The current literature review aims to present the main complication in their use—catheter-related infections. The different types of infectious complications, their pathogenesis, their laboratory diagnostics, and practical guidelines for the behavior of each of them are examined. [ABSTRACT FROM AUTHOR]

The article presents the spectrum of microflora in patients with urolithiasis in various biological fluids: blood, urine naturally collected, and the nephrostomy tube fluid. It was found that the most common bacteria were E. coli and Enterococcus. Resistance of bacteria to antibiotics was also analyzed. The high level of antibiotic resistance was revealed which made the treatment of such patients very difficult.

Surgical site infections remain a major complication of arthroplasty, spinal stabilization or other orthopedic surgeries. The pathogenesis of these complications is related to use orthopedic implants. This retrospective study investigated the microbiological etiology of implant-associated infection after orthopedic surgery over a 3-year period (2010-2012). The antibiotic resistance profiles of 1350 clinical microbial isolates were determined. The biofilm forming capacity of 394 staphylococcal strains was tested. Statistical analysis was performed using Z-criterion. From a results of the microbiological culture, Staphylococcus aureus and Staphylococcus epidermidis were isolated in 49,9% of cases, followed by: Enterococcus faecalis - 6,4%, Pseudomonas aeruginosa - 5,9%, Acinetobacter spp - 5,1% and members of the family Enterobacteriaceae - 4.1%. MRSA amounted to 23,9% and MRSE - 56,6% (p

Background: Postoperative infection delays postoperative adjuvant therapy and can lead to poor prognosis in gastric cancer patients. Therefore, accurately identifying patients at high risk of postoperative infection in patients with gastric cancer is critical. We therefore conducted a study to analyze the impact of postoperative infection complications on long-term prognosis., Methods: From January 2014 to December 2017, we retrospectively collected the data of 571 patients with gastric cancer admitted to the Affiliated People's Hospital of Ningbo University. The patients were divided into an infection group (n=81) and control group (n=490) according to whether the patients experienced postoperative infection. The clinical characteristics of the 2 groups were compared, and the risk factors of postoperative infection complications in patients with gastric cancer were analyzed. Finally, the prediction model of postoperative infection complications was established., Results: There were significant differences in age, diabetes, preoperative anemia, preoperative albumin, preoperative gastrointestinal obstruction, and surgical methods between the 2 groups (P<0.05). Compared with that in the control group, the mortality rate of patients in the infection group at 5 years after surgery was significantly increased (39.51% vs. 26.12%; P=0.013). Multivariate logistics regression analysis showed that age >65 years, preoperative anemia, albumin <30 g/L, and gastrointestinal obstruction were risk factors of postoperative infection in patients with gastric cancer (P<0.05). The data set was randomly divided into a training set and validation set; the sample size of the training set was 286 while the sample size of the validation set was 285. In terms of the predictive model's value in predicting postoperative infection in patients with gastric cancer, the area under the curve of the receiver operating characteristic (ROC) curve in the training set was 0.788 (95% confidence interval: 0.711-0.864), and the area under the curve of the ROC curve in the validation set was 0.779 (95% confidence interval: 0.703-0.855). In the validation set, the model was evaluated with the Hosmer-Lemeshow goodness-of-fit test, resulting in a chi-squared value of 5.589 and a P value of 0.693., Conclusions: The present model can effectively identify patient as high risk of postoperative infection., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jgo.amegroups.com/article/view/10.21037/jgo-23-231/coif).

Many assume antibiotics are a simple solution to infectious complications, which is not always the case. Clinicians must explain the downstream effects of traumatic injuries and ICU care to families in detail so they can see how each bump in the road will affect the patient. [ABSTRACT FROM AUTHOR]

Background: Deep Neck Infections (DNIs) spread along fascial planes and involve neck spaces. Recently, their incidence has decreased due to the introduction of antibiotics; nevertheless, complications related to DNIs are often life-threatening., Objective: The purpose of this article is focused on the identification of predisposing factors of these complications, as well as on the development of a reliable therapeutic algorithm., Methods: Sixty patients with DNIs were enrolled from 2006 to 2019 for a retrospective study. The exclusion criteria for the present study were cellulitis, small abscesses responding to empiric or specific antibiotic therapy, or involvement of only one deep neck space. During the analysis, the following parameters of interest have been evaluated: gender, age, site of origin, pathways of spread, comorbidities, clinical features, bacteriology data, type of surgical approach required, complications, duration of hospitalization and mortality rate. On admission, microbial swab analysis was performed., Results: Diabetes Mellitus (DM), Chronic Obstructive Pulmonary Disease (COPD), iron deficiency anemia and the involvement of multiple spaces have been associated with a significantly higher risk of developing complications. Most of our patients had polymicrobial infections. All patients underwent surgical drainage. The complication rate had occurred in 56.6% of patients, while death in 18.3%., Conclusion: DNIs represent a medical and surgical emergency with potentially serious complications; thus, avoidance of diagnostic delay is mandatory. Our preliminary data suggest the importance of evaluating the extent of infections because the involvement of multiple spaces requires timely surgery due to the higher risk of complications and mortality., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

We have compared the clinical and laboratory features as well as treatment complications observed in 6 patients with iatrogenic acute myelogenous leukemia (I-AML) with those of 26 patients with idiopathic acute myelogenous leukemia (AML). I-AML patients were significantly younger and their disease appeared less virulent on admission than in the AML patients. Following identical chemotherapy, hemorrhagic complications and the need for platelet support were found to be similar for both groups. Major infections, including systemic candidiases and Gram-negative septicemias, occurred 3 times more frequently among I-AML than AML patients. More marked suppression and delayed regeneration of the bone marrow also occurred in I-AML patients. These observations and other factors, such as post-splenectomy state and inherent immune deficiency among surgically staged lymphoma patients as well as radiation induced immunologic impairment, may have contributed to the increased propensity to develop infection observed in this group of patients. Five of the 6 I-AML and 17 of the 26 AML patients achieved remission. We attribute the satisfactory outcome in our I-AML patients to treatment in a protective environment and availability of facilities for hematologic supportive care. [ABSTRACT FROM AUTHOR]

Chronic kidney disease (CKD) constitutes a major health problem and one of the leading causes of death worldwide. Patients with CKD have impaired immune functions that predispose them to an increased risk of infections, as well as virus-associated cancers and a diminished vaccine response. In this study, we aimed to identify clinical and laboratory parameters associated with in-hospital mortality in patients evaluated in the department of emergency (ER) and admitted with the diagnosis of severe acute respiratory syndrome (SARS) caused by coronavirus disease 2019 (COVID-19) at the Baptist Hospital of Nicaragua (BHN). There were 37 patients with CKD, mean age 58.3 ± 14.1 years, admitted to BHN due to COVID-19, and among them, 24 (65.7%) were males (p = 0.016). During hospitalization, 23 patients with CKD (62.1%) died of complications associated with COVID-19 disease, which was a higher proportion (odds ratio (OR) 5.6, confidence interval (CI) 2.1–15.7, p = 0.001) compared to a group of 70 patients (64.8% males, mean age 57.5 ± 13.7 years) without CKD admitted during the same period in whom 28.5% died of COVID-19. In the entire cohort, the majority of patients presented with bilateral pneumonia, and the most common symptoms at admission were dyspnea, cough, and fever. Serum levels of D-dimer, ferritin and procalcitonin were significantly higher in patients with CKD compared with those without CKD. Multivariate analysis revealed that CKD, age (>60 years), and hypoxia measured in the ER were factors associated with increased in-hospital mortality. Among patients with CKD but not in those without CKD (OR 36.8, CI 1.5–88.3, p = 0.026), an increased monocytes-to-lymphocyte ratio (MLR) was associated with higher mortality and remained statistically significant after adjusting for confounders. The MLR measured in the ER may be useful for predicting in-hospital mortality in patients with CKD and COVID-19 and could contribute to early risk stratification in this group.

Introduction: The majority of patients with CLL will suffer from infections during their disease, accounting for approximately 60% of deaths in CLL. Patients are predisposed to infection due to immune defects related to the primary disease, and as a result of therapy. The range of infectious complications has evolved alongside therapeutic advances in the treatment of CLL. More recently several novel therapeutic compounds have been introduced in CLL, whose unique safety profiles will probably have an impact on the prophylaxis and management of infections in these patients. Areas covered: This review describes the pathogenesis of infections due to intrinsic CLL or therapy-related immunosuppression, and elightens the importance of proactive and reactive infection management as a key focus of patient care. Infections related to conventional chemotherapy, immunochemotherapy with monoclonal antibodies, target therapies with B-cell receptor pathway inhibitors and Bcl-2 antagonists are reviewed. Expert commentary: Despite the importance of infection management and prevention in high-risk patients, there are only limited infection risk-assessment guidelines that can be easily used in clinical practice to guide more appropriate infection prophylaxis and its management. Here we provide an overview of suggested prophylaxis management of infection, and include key prophylactic interventions that we feel should be performed in CLL patients routinely.
