Abstract Background: Extensively drug-resistant Acinetobacter baumannii (XDRAB) has strong ability to acquire drug resistance genes, which are then rapidly cloned and transmitted, leading to worldwide spread posing a significant treatment challenge. Currently, limited drugs are available for the treatment of XDRAB infection, and their clinical effects are not clear; therefore, the specific factors that affect the treatment response and patient outcome require further exploration. The aim of this was to clarify effective treatment methods during XDRAB infection and the factors affecting patient prognosis according to a retrospective review of cases at our hospital.Methods: Hospital-acquired XDRAB pneumonia cases clinically diagnosed at Guangzhou First Municipal People’s Hospital from January 2016 to December 2017 were selected, and their clinical features, treatment, and prognosis were retrospectively analysed.Results: Forty-eight patients met the diagnostic criteria of hospital-acquired pneumonia caused by XDRAB in the study period, 20 of whom survived and 28 of whom died for an overall mortality rate of 58.3%. There was no significant difference in anti-A. baumannii activity according to the type of antibiotic administered or their combinations between the patients that survived and those that died from the infection. The use of antibacterial drugs during infection did not effectively improve the clinical outcome. Advanced age, multiple organ failure, and disease severity (APACHE score) were significantly negatively correlated with bacterial clearance, whereas effective airway management (tracheotomy and sputum suction during infection) had a positive impact on bacterial clearance. In multivariate analysis, age [odds ratio (OR) 1.1, 95% confidence interval (CI) 1.0–1.3] and APACHE score (OR 1.5, 95% CI 1.1–2.0) were independent risk factors affecting prognosis. Tracheotomy during infection (OR 0.0, 95% CI 0.0–0.55) was a protective factor contributing to survival.Conclusion: XDRAB hospital-acquired pneumonia has a high mortality rate. Advanced age and severe disease are independent risk factors that affect patient prognosis. The use and type of antibacterial drugs for treatment do not appear to substantially affect the prognosis during XDRAB infection. Overall, timely and effective airway management is the key to improving the prognosis of patients with hospital-acquired XDRAB infection.

Hospital acquired pneumonia (HAP) is common and often associated with high mortality in children aged five or less. We sought to evaluate the risk factors and outcome of HAP in such children. We compared demographic, clinical, and laboratory characteristics in children <5 years using a case control design during the period of August 2013 and December 2017, where children with HAP were constituted as cases (n = 281) and twice as many randomly selected children without HAP were constituted as controls (n = 562). HAP was defined as a child developing a new episode of pneumonia both clinically and radiologically after at least 48 h of hospitalization. A total of 4101 children were treated during the study period. The mortality was significantly higher among the cases than the controls (8% vs. 4%, p = 0.014). In multivariate logistic regression analysis, after adjusting for potential confounders, it was found that persistent diarrhea (95% CI = 1.32–5.79; p = 0.007), severe acute malnutrition (95% CI = 1.46–3.27; p < 0.001), bacteremia (95% CI = 1.16–3.49; p = 0.013), and prolonged hospitalization of >5 days (95% CI = 3.01–8.02; p < 0.001) were identified as independent risk factors for HAP. Early identification of these risk factors and their prompt management may help to reduce HAP-related fatal consequences, especially in resource limited settings.

Abstract Background Extremely drug-resistant (XDR) Acinetobacter baumannii （A. baumannii）has been of a great concern. The relationship between XDR and patient outcomes remains unclear. We investigated the clinical features, risk factors, and outcomes of Hospital-acquired pneumonia (HAP)caused by XDR A. baumannii. Methods A multicenter retrospective case-control study was performed to determine factors associated with XDR A. baumannii pneumonia from 5 teaching hospitals in Guangzhou, China. Results 76 patients were enrolled in the study. XDR A. baumannii pneumonia patients were tend to be smoker (11.9% vs 3.9%, P = 0.130) and older (76.5±11.2 vs 70.3±16.4, P = 0.007) and had more comorbid diseases including chronic obstructive pulmonary disease (COPD) (48.7% vs 21.1%, P = 0.001) and renal failure (21.1% vs 3.9%, P = 0.002) and had higher APACHE II score (65.8% vs 47.4%, P = 0.033). Invasive procedures including insertion of urinary catheter, nasogastric tube, central venous/arterial catheter, bronchoscopy and mechanical ventilation along with using β-lactam/β-lactamase inhibitor and carbapenem were also risk factors for XDR A. baumannii pneumonia. Multivariate analysis showed the APACHE II score >=20 (OR, 2.1; 95% CI: 1.1–4.1, P = 0.023), COPD (OR, 9.6; 95% CI: 2.0–45.5, P = 0.004), central venous/arterial catheter placement (OR,11.5; 95% CI: 1.1-117.8, P = 0.040), low albumin levels (OR, 1.2; 95% CI: 1.1-1.4, P = 0.001) and using β-lactam/β-lactamase inhibitor (OR,15.9; 95% CI: 2.7-94.2, P = 0.002) were independent risk factors for XDR A. baumannii pneumonia. Compared with the non-XDR A. baumannii patients, the XDR A. baumannii pneumonia increased length of mechanical ventilation (11.1±12.3 vs 5.1±5.6, P = 0.000), hospital stay (42.2±24.3 vs 34.8±18.0, P = 0.036) and ICU (Intensive Care Unit) stay (27.5±19.0 vs 20.0±20.5, P = 0.020), but it did not increase in-hospital mortality (47.4% vs 32.9%, P = 0.137). Conclusions XDR A. baumannii pneumonia was strongly related to systemic illnesses, invasive procedure, low albumin levels and the APACHE II score and increasing the length of mechanical ventilation and hospital stay. But it did not increase in-hospital mortality.

This study investigates the prognostic value of immune cell subsets in assessing the risk of death in patients with sepsis. This retrospective study collected 169 patients from March 2020 to February 2021 at our hospital. Baseline data were collected from patients. The absolute values (Abs) and percentages (%) of immune cell subsets for lymphocytes, T cells, CD4+ cells, CD8+, B cells, NK cells, and NKT cells were measured using flow Cytometry. Among the included patients, 43 patients were in the nonsurvivor group and 126 patients were in the survivor group. The age of patients in the nonsurvivor survivor was higher than that of survivor group patients ( P = .020). SOFA, APACHE II, C-reactive protein, and procalcitonin were higher in the nonsurvivor group than in the survivor group (all P values < .05). Multivariate regression analysis showed that lymphocytes (%) and SOFA were independent risk factors affecting patients’ prognosis. Lymphocytes (%) have the highest area under the receiver operating characteristic (ROC) curve (0.812). The model area under the ROC curve for immune cell subsets was 0.800, with a sensitivity of 72.09%, and specificity of 79.27% ( z = 7.796, P <  .001). Analysis of patient prognosis by immune cell subsets diagnostic showed statistically significant differences in the grouping of cut-off values for all 5 indicators (all P < .05). The lymphocytes (%) and SOFA score are independent risk factors affecting the prognosis of patients. A moderate predictive power for mortality in sepsis patients by immune cell subsets model.

Pressure injuries remain a serious health complication for patients and nursing staff. Evidence from the past decade has not been analysed through narrative synthesis yet. PubMed, Embase, CINAHL Complete, Web of Science, Cochrane Library, and other reviews/sources were screened. Risk of bias was evaluated using a slightly modified QUIPS tool. Risk factor domains were used to assign (non)statistically independent risk factors. Hence, 67 studies with 679,660 patients were included. In low to moderate risk of bias studies, non-blanchable erythema reliably predicted pressure injury stage 2. Factors influencing mechanical boundary conditions, e.g., higher interface pressure or BMI < 18.5, as well as factors affecting interindividual susceptibility (male sex, older age, anemia, hypoalbuminemia, diabetes, hypotension, low physical activity, existing pressure injuries) and treatment-related aspects, such as length of stay in intensive care units, were identified as possible risk factors for pressure injury development. Health care professionals’ evidence-based knowledge of above-mentioned risk factors is vital to ensure optimal prevention and/or treatment. Openly accessible risk factors, e.g., sex, age, BMI, pre-existing diabetes, and non-blanchable erythema, can serve as yellow flags for pressure injury development. Close communication concerning further risk factors, e.g., anemia, hypoalbuminemia, or low physical activity, may optimize prevention and/or treatment. Further high-quality evidence is warranted.

Introduction: We aimed to determine risk factors for nephrotoxicity and factors affecting mortality in patients who received colistin. Methodology: Critical patients who received colistin were enrolled. Pregnancy, age < 18 years, basal creatinine level > 2 mg/dL, colistin use for < 48 hours, and previous renal replacement therapy were exclusion criteria. KDIGO stages were determined according to creatinine levels. Patients were grouped as those with no acute kidney injury (Group N0) and those with acute kidney injury (Group N). Their demographic data, APACHE II and SOFA scores, treatments, and laboratory results were recorded. Results: A total of 91 patients were included: 27 in Group N0 and 64 in Group N. Demographic data were similar between groups; however, higher admission APACHE-II scores (OR:1.179, 95% CI:1.033-1.346, p = 0.015) and need for vasopressors (OR:5.486, 95% CI:1.522–19.769, p = 0.009) were found to be independent risk factors for nephrotoxicity. Higher APACHE II scores (OR:1.253, %95 CI:1.093-1.437, p = 0.001), presence of coronary artery disease (OR:7.720, % 95 CI: 1.613-36.956, p = 0.011), need for vasopressors (OR: 4.587, % 95 CI: 1.224 – 17.241, p = 0.024), hypoalbuminemia (OR: 4.721, % 95 CI: 1.088 – 20.469, p = 0.038), and higher direct bilirubin levels (OR: 1.806, % 95 CI: 1.055 – 3.092, p = 0.031) were independent risk factors for mortality. Conclusion: When use of colistin is considered in ICU patients, presence of modifiable risk factors for nephrotoxicity such as hypoalbuminemia, nephrotoxic drug administration, and presence of shock should be determined and managed to prevent nephrotoxicity.
