Objective.To assess the prevalence of and risk factors for carbapenem-resistantKlebsiella pneumoniae(CRKP) carriage among patients in post-acute-care facilities (PACFs) in Israel.Design, Setting, and Patients.A cross-sectional prevalence survey was conducted in 12 PACFs. Rectal swab samples were obtained from 1,144 patients in 33 wards. Risk factors for CRKP carriage were assessed among the cohort. Next, a nested, matched case-control study was conducted to define individual risk factors for colonization. Finally, the cohort of patients with a history of CRKP carriage was characterized to determine risk factors for continuous carriage.Results.The prevalence of rectal carriage of CRKP among 1,004 patients without a history of CRKP carriage was 12.0%. Independent risk factors for CRKP carriage were prolonged length of stay (odds ratio [OR], 1.001;P< .001), sharing a room with a known carrier (OR, 3.09;P= .02), and increased prevalence of known carriers on the ward (OR, 1.02;P= .013). A policy of screening for carriage on admission was protective (OR, 0.41;P= .03). Risk factors identified in the nested case-control study were antibiotic exposure during the prior 3 months (OR, 1.66;P= .03) and colonization with other resistant pathogens (OR, 1.64;P= .03). Among 140 patients with a history of CRKP carriage, 47% were colonized. Independent risk factors for continued CRKP carriage were antibiotic exposure during the prior 3 months (OR, 3.05;P= .04), receipt of amoxicillin-clavulanate (OR, 4.18;P= .007), and screening within 90 days of the first culture growing CRKP (OR, 2.9;P= .012).Conclusions.We found a large reservoir of CRKP in PACFs. Infection-control polices and antibiotic exposure were associated with patient colonization.

The aims of the present research are to investigate the possible predictors of pancreatic cancer, in particular smoking status, alcohol consumption, hypercholesterolemia, and diabetes mellitus, in patients with histologically confirmed pancreatic carcinoma and to examine the synergism between risk factors. A case-control study (80 patients and 392 controls) was conducted at the Teaching Hospital “Agostino Gemelli” in Rome. A conditional logistic regression was used for the statistical analysis and results were presented as odds ratio (OR) and 95% confidence intervals (95% CI). We also investigated the possible interactions between risk factors and calculated the synergism index (SI). The multivariate analysis revealed that hypercholesterolemia and alcohol consumption resulted in important risk factors for pancreatic cancer even after the adjustment for all variables (OR: 5.05, 95% CI: 2.94–8.66; OR: 2.25, 95% CI: 1.30–3.89, resp.). Interestingly, important synergistic interactions between risk factors were found, especially between ever smoking status and alcohol consumptions (SI = 17.61) as well as alcohol consumption and diabetes (SI = 17.77). In conclusion, the study confirms that hypercholesterolemia and alcohol consumption represent significant and independent risk factors for pancreatic cancer. Moreover, there is evidence of synergistic interaction between diabetes and lifestyle factors (drinking alcohol and eating fatty foods).

AbstractVenous thromboembolism (VTE) is a serious complication in paediatric oncology patients. To identify the incidence, risk factors and recurrence rate of VTE in paediatric oncology patients, an observational, retrospective cohort study of all consecutive children (≤18 years) with malignancies, treated at the Emma Children's Hospital Academic Medical Centre between January 1989 and December 2013, was done. A matched case–control study in children with lymphomas was performed, to identify thrombotic risk factors. Cumulative recurrence-free survival after first VTE was estimated by the Kaplan–Meier method. Of the 2,183 children included (male: female = 1.4:1.0; median age, 6.6 years) with cancer, 78 patients developed VTE (3.6%; 95% confidence interval [CI], 2.8–4.4). The incidence increased from 0.8% (4/478, 95% CI, 0.0–1.6) between 1989 and 1993 to 10.4% (44/423, 95% CI, 7.6–13.4) between 2009 and 2013. Independent risk factors for VTE were age ≥ 12 years, acute lymphoblastic leukaemia (ALL) and lymphoma. The case–control study in lymphoma patients showed a trend for increased VTE incidence in stage IV lymphoma. Twelve (15.4%) patients developed recurrent thrombosis, 7 patients while on therapeutic or prophylactic anticoagulation. The cumulative recurrence-free survival after first VTE was 88.5, 87.1 and 80.6% after 1, 5 and 10 years, respectively. In conclusion, we demonstrated an increasing incidence of VTE in children with malignancies, with age ≥ 12 years, ALL and lymphoma as independent risk factors. The elevated recurrence rate underlines the importance of full anticoagulant therapy and might warrant prophylactic anticoagulation after first VTE during cancer treatment.

Background. Difficult peripheral intravenous cannulation (DPIVC) is associated with serious complications related to vascular access. These complications might be avoided if the risk factors were identified previously, enabling the detection of potentially difficult situations at an early stage. The aim of this study is to consider these risk factors, to determine the influence of the hospital setting, to examine the association between DPIVC and the different techniques of catheter insertion and to analyse the importance of the clinician’s experience in this context. Methods. Case-control study following a previously published protocol, conducted in 48 units of eight public hospitals in Spain. Adult patients requiring a peripheral intravenous cannula were prospectively included in the study population during their hospital stay. Over a period of 11 months, for consecutive eligible patients, nurses in each participating unit recorded data on their assessment of the vascular access performed and the technique used. Variables related to these medical personnel were also recorded. One of the researchers reviewed the patients’ clinical history to compile the relevant health variables and to characterise the healthcare process. The statistical analysis included association tests among the main study variables. The risk factors were analysed using bivariate logistic regression. The variables found to be statistically significant were included in a multivariate logistic regression model incorporating each of the healthcare environments identified. Results. The study population was composed of 2662 patients, of whom 221 (8.3%) presented with DPIVC. A previous history of difficulty, the presence of non-palpable veins, acute upper limb alterations and punctures in the ante-cubital fossa were found to be independent risk factors for DPIVC. Differences were found in the frequency of occurrence of DPIVC and in some risk factors, according to the healthcare context. The variables related to the characteristics of the hospital personnel did not influence the study event. Conclusion: The present study identifies four independent risk factors for DPIVC that can be incorporated into algorithms aimed at preventing its occurrence and facilitating the referral of patients to vascular access specialist teams.

A retrospective case–case control study was conducted, including 60 cases with daptomycin-nonsusceptible vancomycin-resistant enterococci (DNS-VRE) matched to cases with daptomycin-susceptible VRE and to uninfected controls (1:1:3 ratio). Immunosuppression, presence of comorbid conditions, and prior exposure to antimicrobials were independent predictors of DNS-VRE, although prior daptomycin exposure occurred rarely. In summary, a case–case control study identified independent risk factors for the isolation of DNS-VRE: immunosuppression, multiple comorbid conditions, and prior exposures to cephalosporines and metronidazole.

Abstract Background: Multiple organ dysfunction syndrome (MODS) with secondary hemophagocytic lymphohistiocytosis (SHLH) causes significant mortality, while continuous renal replacement therapy (CRRT) is commonly conducted. The objective is to identify the predictor factors associated with poor outcomes in pediatric patients with SHLH -associated MODS who received CRRT. Methods: A multicenter prospective nested case-control study in four PICUs of tertiary university children’s hospital in Shanghai from September 2013 to August 2018.We prospectively studied 52 SHLH-associated MODS pediatric patients receiving CRRT. Results: Overall PICU mortality rate was 46.15%(24/52). Less respiratory (28.6% vs. 87.5%, P <0.001) or cardiovascular dysfunction (25% vs. 83.3%, P <0.001) caused in survivors at CRRT initiation, as well as reduced demands of mechanical ventilation and vasoactive agents (28.6% vs. 87.5%,17.9 % vs. 66.7 %, both P <0.001). Non-survivors had higher levels of serum lactate dehydrogenase (1404.5 (713.25, 2793) vs. 982.7 (692, 1461) (U/L), P = 0.037), lactic acid (1.9 (1.3, 4.53) (mmol/L) vs. 1.65 (0.8, 2.45) , P=0.034), triglyceride (2.88 (1.94, 5.08) (mmol/L) vs. 2.41 (1.63, 3.32), P=0.032) and IL-6 (28.66 (17.77, 113.63) (pg/ml) vs.0.98 (0.1, 4.63) P=0.000). More than 3 organ dysfunction (Odd ratio [ OR ] : 3.464; 95% confidence interval [ CI ] [1.018-11.788], P = 0.047), and the serum IL-6 level higher than 13.12 pg/mL ( OR :1.388; 95% CI [1.058-1.821], P = 0.018 ) were two independent risk factors for mortality. Conclusions: The number of organ dysfunction and IL-6 levels at CRRT initiation are the independent risk factors for mortality in SHLH-associated MODS patients.
