One of the most common complications after cardiac surgery with cardiopulmonary bypass (CBP) is delirium. The purpose of this study was to prospectively investigate the risk of developing postoperative delirium in a group of elderly patients using a multivariate assessment of preoperative and intraoperative risk factors. A total of 149 elderly patients were included. Thirty patients (20%) developed post-operative delirium. Preoperative procalcitonin (PCT) above the reference range (>0.05 ng/mL) was recorded more often in patients who postoperatively developed delirium than in the non-delirium group (50% vs. 27%, p = 0.019). After surgery, PCT was significantly higher in the delirium than the non-delirium group: ICU admission after surgery: 0.08 ng/mL vs. 0.05 ng/mL p = 0.011), and for consecutive days (day 1: 0.59 ng/mL vs. 0.25 ng/mL, p = 0.003; day 2: 1.21 ng/mL vs. 0.36 ng/mL, p = 0.006; day 3: 0.76 ng/mL vs. 0.34 ng/mL, p = 0.001). Patients with delirium were older (74 vs. 69 years, p = 0.038), more often had impaired daily functioning (47% vs. 28%, p = 0.041), depressive symptoms (40% vs. 17%, p = 0.005), and anemia (43% vs. 19%, p = 0.006). In a multivariable logistic regression model, preoperative procalcitonin (odds ratio (OR) = 3.05), depressive symptoms (OR = 5.02), age (OR = 1.14), impaired daily functioning (OR = 0.76) along with CPB time (OR = 1.04) were significant predictors of postoperative delirium.

Abstract Background One of the most common complications after cardiac surgery is delirium. Determining the origin of this complication from possible pathomechanisms is difficult. The activation of an inflammatory response during surgery has been suggested as one possible mechanism of delirium. The usefulness of the inflammatory marker procalcitonin (PCT) as a predictor of delirium after cardiac surgery with cardiopulmonary bypass (CBP) has not yet been investigated. Methods The purpose of this study was to prospectively investigate the risk of developing postoperative delirium in a group of elderly patients using a multivariate assessment of preoperative (PCT, comorbidities, functional decline, depression) and intraoperative risk factors. 149 elderly patients were included. Delirium was assessed using the Confusion Assessment Method for the ICU. Results Thirty patients (20%) developed post-operative delirium: hypoactive in 50%, hyperactive in 33%, mixed in 17%. Preoperative PCT above the reference range (> 0.05 ng/mL) was recorded more often in patients who postoperatively developed delirium than in the non-delirium group (50% vs. 27%, p=0.019). After surgery, PCT was significantly higher in the delirium than the non-delirium group: ICU admission after surgery: 0.08 ng/mL, IQR 0.03-0.15 vs. 0.05 ng/mL, IQR 0.02-0.09, p=0.011), and for consecutive days (day 1: 0.59 ng/mL, IQR 0.25-1.55 vs. 0.25 ng/mL, IQR 0.14-0.54, p=0.003; day 2: 1.21 ng/mL, IQR 0.24-3.29 vs. 0.36 ng/mL, IQR 0.16-0.76, p=0.006; day 3: 0.76 ng/mL, IQR 0.48-2.34 vs. 0.34 ng/mL, IQR 0.14-0.66, p=0.001). Patients with delirium were older (74 years, IQR 70 – 76 vs. 69 years, IQR 67 – 74; p=0.038) and more often had functional decline (47% vs. 28%, p=0.041). There was no difference in comorbidities with the exception of anaemia (43% vs. 19%, p=0.006). Depression was detected in 40% of patients with delirium and in 17% without delirium (p=0.005). In a multivariable logistic regression model of preoperative procalcitonin (OR= 3.05; IQR 1.02-9.19), depression (OR=5.02, IQR 1.67-15.10), age (OR=1.14; IQR 1.02-1.26), functional decline (OR=0.76; IQR 0.63-0.91) along with CPB time (OR=1.04; IQR 1.02-1.06) were significant predictors of postoperative delirium. Conclusion A preoperative PCT test and assessment of functional decline and depression may help identify patients at risk for developing delirium after cardiac surgery.

<b><i>Introduction:</i></b> In patients with atrial fibrillation (AF) at risk for stroke, dabigatran 150 mg twice a day (DE150) is superior to warfarin for stroke prevention. However, there is paucity of data with respect to bleeding risk at this dose in elderly patients (≥75 years). We aimed to evaluate the safety of DE150 in comparison to warfarin in a real-world population with AF and low bleeding risk (HAS-BLED score ≤2). <b><i>Methods:</i></b> In this prospective observational study, 754 consecutive patients with AF and HAS-BLED score ≤2 were included. We compared outcome of elderly patients (age ≥75 tears) to younger patients (age &#x3c;75 years). The primary end point was the combined incidence of all-cause mortality, stroke, systemic emboli, and major bleeding event during a mean follow-up of 1 year. <b><i>Results:</i></b> There were 230 (30%) elderly patients, 151 patients were treated with warfarin, and 79 were treated with DE150. Fifty-two patients experienced the primary endpoint during the 1-year follow-up. Among the elderly, at 1-year of follow-up, the cumulative event rate of the combined endpoint in the DE150 and warfarin was 8.9 and 15.9% respectively (<i>p</i> = 0.14). After adjustment for age and gender, patients who were treated with DE150 had a nonsignificant difference in the risk for the combined end point as patients treated with warfarin both among the elderly and among the younger population (HR 0.58, 95% C.I = 0.25–1.39 and HR = 1.12, 95% C.I 0.62–2.00, respectively [<i>p</i> for age-group-by-treatment interaction = 0.83). <b><i>Conclusions:</i></b> Our results suggest that Dabigatran 150 mg twice a day can be safely used among elderly AF patients with low bleeding risk.

Abstract Background Postoperative delirium (POD) is a relevant and underdiagnosed complication after cardiac surgery that is associated with increased intensive care unit (ICU) and hospital length of stay (LOS). The aim of this subgroup study was to compare the frequency of tested POD versus the coded International Statistical Classification of Diseases and Related Health Problems (ICD) diagnosis of POD and to evaluate the influence of POD on LOS in ICU and hospital. Methods 254 elective cardiac surgery patients (mean age, 70.5 ± 6.4 years) at the University Hospital Bonn between September 2018 and October 2019 were evaluated. The endpoint tested POD was considered positive, if one of the tests Confusion Assessment Method for ICU (CAM-ICU) or Confusion Assessment Method (CAM), 4 'A's Test (4AT) or Delirium Observation Scale (DOS) was positive on one day. Results POD occurred in 127 patients (50.0%). LOS in ICU and hospital were significantly different based on presence (ICU 165.0 ± 362.7 h; Hospital 26.5 ± 26.1 days) or absence (ICU 64.5 ± 79.4 h; Hospital 14.6 ± 6.7 days) of POD (p < 0.001). The multiple linear regression showed POD as an independent predictor for a prolonged LOS in ICU (48%; 95%CI 31–67%) and in hospital (64%; 95%CI 27–110%) (p < 0.001). The frequency of POD in the study participants that was coded with the ICD F05.0 and F05.8 by hospital staff was considerably lower than tests revealed by the study personnel. Conclusion Approximately 50% of elderly patients who underwent cardiac surgery developed POD, which is associated with an increased ICU and hospital LOS. Furthermore, POD is highly underdiagnosed in clinical routine.

Purpose: To analyze spread of odontogenic infections in the elderly, especially the prevalence and characteristic multidetectorcomputed tomography (MDCT) findings.Materials and methods: Ninety-seven patients with odontogenic infection who underwent 64-row MDCT were evaluated inthis study. The study patients comprised 31 elderly patients (60 years) and 66 adults (< 60 years). Age, gender, location ofcausal tooth, and spread of odontogenic infections with MDCT were analyzed.Results: The elderly patients (74.2%) had higher ratio with female compared to the adults (57.6%). The buccal space (93.5%)was the most common spread of odontogenic infections for the elderly patients, followed by the masticator space (54.8%) andsubmandibular space (45.2%), whereas the buccal space (97.0%) was the most common spread of odontogenic infections for theadults, followed by submandibular space (65.2%) and masticator space (51.5%). Logistic multivariate regression analysis forodontogenic infections in the elderly demonstrated that the gender (odds ratio = 3.462, P = .024) and submandibular space (oddsratio = 0.168, P = .013) were significant variable.Conclusions: The study showed the prevalence and characteristic MDCT findings of spread of odontogenic infections in theelderly.
