Neurocognitive impairment, employment, and social status in radiotherapy-treated adult survivors of childhood brain tumors
Background. Little is known of the cognitive functions, employment, and social status in adult survivors of childhood brain tumor (BT). We aimed to determine the long-term neurocognitive profile of radiotherapy-treated adult survivors of childhood BT and the relationship between cognitive functions and employment and social status. Methods. Neurocognitive profiles of survivors were assessed in a Finnish national cohort of 71 radiotherapy-treated survivors of childhood BT (median follow-up time: 21 years [range: 5-33 years]) using a cross-sectional design. Neurocognitive outcomes were compared to control (n = 45) and normative values. Tumor- and treatment-related data were collected from the patient files. Information on employment and social status was gathered. Results. Survivors' (median age: 27 years [range: 16-43 years]) median verbal and performance intelligence quotient (IQ) was 90 (range: 49-121) and 87 (range: 43-119), respectively. The cognitive domains with the greatest impairment were executive functions (median z score, 3.5 SD [range: -25.0 to 1.3 SD]), and processing speed and attention (median z score, -2.5 SD [range: -24.9 to 0.5 SD]). Executive functions were associated with employment, educational level, living independently, having an intimate relationship, and having a driving license. Processing speed and attention were related to educational level, living independently, having an intimate relationship, and having a driving license. Performance IQ was associated with educational level and employment status. Working memory was associated with educational level and living independently. Conclusions. Radiotherapy-treated adult survivors of childhood BT experience significant neurocognitive impairment, which is associated with difficulties related to employment and social status.Peer reviewe
Effect of Inhaled Xenon on Cardiac Function in Comatose Survivors of Out-of-Hospital Cardiac Arrest—A Substudy of the Xenon in Combination With Hypothermia After Cardiac Arrest Trial
OBJECTIVES: This explorative substudy aimed at determining the effect ofinhaled xenon on left ventricular function by echocardiography in comatose survivorsof out-of-hospital cardiac arrest.DESIGN: A randomized two-group single-blinded phase 2 clinical drug trial.SETTING: A multipurpose ICU in two university hospitals.PATIENTS: Of the 110 randomized comatose survivors after out-of-hospital cardiacarrest with a shockable rhythm in the xenon in combination with hypothermiaafter cardiac arrest trial, 38 patients (24–76 yr old) with complete echocardiographywere included in this study.INTERVENTIONS: Patients were randomized to receive either inhaled xenoncombined with hypothermia (33 C) for 24 hours or hypothermia treatment alone.Echocardiography was performed at hospital admission and 24 4 hours afterhypothermia.MEASUREMENTS AND MAIN RESULTS: Left ventricular ejection fraction,myocardial longitudinal systolic strain, and diastolic function were analyzedblinded to treatment. There were 17 xenon and 21 control patients in whom echocardiographywas completed. Clinical characteristics did not differ significantlybetween the groups. At admission, ejection fraction was similar in xenon and controlpatients (39% 10% vs 38% 11%; p = 0.711) but higher in xenon thancontrol patients after hypothermia (50% 10% vs 42% 10%; p = 0.014).Global longitudinal systolic strain was similar in xenon and control patients atadmission (–9.0% 3.8% vs –8.1% 3.6%; p = 0.555) but better in xenonthan control patients after hypothermia (–14.4.0% 4.0% vs –10.5% 4.0%;p = 0.006). In patients with coronary artery disease, longitudinal strain improved inthe nonischemic myocardial segments in xenon patients. There were no changesin diastolic function between the groups.</p

Inhaled Xenon Attenuates Myocardial Damage in Comatose Survivors of Out-of-Hospital Cardiac Arrest The Xe-Hypotheca Trial
Marjaana Tiainen on Xe-HYPOTHECA Study Grp -työryhmän jäsen.BACKGROUND The authors previously reported that inhaled xenon combined with hypothermia attenuates brain white matter injury in comatose survivors of out-of-hospital cardiac arrest (OHCA). OBJECTIVES A pre-defined secondary objective was to assess the effect of inhaled xenon on myocardial ischemic damage in the same study population. METHODS A total of 110 comatose patients who had experienced OHCA from a cardiac cause were randomized to receive either inhaled xenon (40% end-tidal concentration) combined with hypothermia (33 degrees C) for 24 h (n = 55; xenon group) or hypothermia treatment alone (n = 55; control group). Troponin-T levels were measured at hospital admission, and at 24 h, 48 h, and 72 h post-cardiac arrest. All available cases were analyzed for troponin-T release. RESULTS Troponin-T measurements were available from 54 xenon patients and 54 control patients. The baseline characteristics did not differ significantly between the groups. After adjustments for age, sex, study site, primary coronary percutaneous intervention (PCI), and norepinephrine dose, the mean +/- SD post-arrival incremental change of the ln-transformed troponin-T at 72 h was 0.79 +/- 1.54 in the xenon group and 1.56 +/- 1.38 in the control group (adjusted mean difference -0.66; 95% confidence interval: -1.16 to -0.16; p = 0.01). The effect of xenon on the change in the troponin-T values did not differ in patients with or without PCI or in those with a diagnosis of ST-segment elevation myocardial infarction (group by PCI or ST-segment elevation myocardial infarction interaction effect; p = 0.86 and p = 0.71, respectively). CONCLUSIONS Among comatose survivors of OHCA, in comparison with hypothermia alone, inhaled xenon combined with hypothermia suggested a less severe myocardial injury as demonstrated by the significantly reduced release of troponin-T.

Radiation-induced accelerated aging of the brain vasculature in young adult survivors of childhood brain tumors
Background. Cranial radiotherapy may damage the cerebral vasculature. The aim of this study was to understand the prevalence and risk factors of cerebrovascular disease (CVD) and white matter hyperintensities (WMHs) in childhood brain tumors (CBT) survivors treated with radiotherapy. Methods. Seventy CBT survivors who received radiotherapy were enrolled in a cross-sectional study at a median 20 years after radiotherapy cessation. The prevalence of and risk factors for CVD were investigated using MRI, MRA, and laboratory testing. Tumors, their treatment, and stroke-related data were retrieved from patients' files. Results. Forty-four individuals (63%) had CVD at a median age of 27 years (range, 16-43 years). The prevalence rates at 20 years for CVD, small-vessel disease, and large-vessel disease were 52%, 38%, and 16%, respectively. Ischemic infarcts were diagnosed in 6 survivors, and cerebral hemorrhage in 2. Lacunar infarcts were present in 7, periventricular or deep WMHs in 34 (49%), and mineralizing microangiopathy in 21 (30%) survivors. Multiple pathologies were detected in 44% of the participants, and most lesions were located in a high-dose radiation area. Higher blood pressure was associated with CVD and a presence of WMHs. Higher cholesterol levels increased the risk of ischemic infarcts and WMHs, and lower levels of high-density lipoprotein and higher waist circumference increased the risk of lacunar infarcts. Conclusions. Treating CBTs with radiotherapy increases the risk of early CVD and WMHs in young adult survivors. These results suggest an urgent need for investigating CVD prevention in CBT patients.Peer reviewe
