Multicenter StudyIn-Hospital Mortality and Long-Term Survival of Patients With Acute Intoxication Admitted to the ICU.
To assess in-hospital and long-term mortality of Dutch ICU patients admitted with an acute intoxication. ⋯ Overall, the mortality 2 years after ICU admission is relatively low compared with other ICU admissions. The first 3 months after ICU admission there is a difference in mortality between the subgroups, not thereafter. Still, the difference between the in-hospital mortality and the mortality after 2 years is substantial.

Atrial fibrillation (AF) is more likely to develop in patients with chronic kidney disease (CKD) than in individuals with normal renal function, and patients with CKD are more likely to suffer ischemic stroke (IS)/thromboembolism (TE). To our knowledge, no prior study has considered the impact of estimated glomerular filtration rate (eGFR) on bleeding. We investigated the relationship of eGFR to IS/TE, mortality, and bleeding in an AF population unrestricted by age or comorbidity. ⋯ Incidence rates of IS/TE, mortality, and bleeding increased with reducing eGFR across the whole range of renal function. OAC use was associated with a lower incidence of IS/TE and mortality at 1 year compared with individuals not receiving anticoagulants in all categories of renal function as measured by eGFR. The NCB balancing IS against serious bleeding was positive in favor of OAC use among patients with renal impairment.

Comparative Study
A Comparison of Health-Related Quality of Life in Idiopathic Pulmonary Fibrosis and Chronic Hypersensitivity Pneumonitis.
Patients with interstitial lung disease (ILD) have poor health-related quality of life (HRQL). However, whether HRQL differs among different subtypes of ILD is unclear. The aim of this study was to determine whether HRQL was different among patients with idiopathic pulmonary fibrosis (IPF) and chronic hypersensitivity pneumonitis (CHP). ⋯ HRQL is worse in CHP compared with IPF. HRQL differences between ILD subtypes are explained in part by differences in sex, dyspnea, and fatigue.

Hyperinflation refers to a nonspecific increase in absolute lung volumes and has a poor prognosis in COPD. The relative contribution of increased airways resistance and increased parenchymal compliance to hyperinflation of each absolute lung volume is poorly understood. We hypothesized that increased residual volume (RV) and RV/total lung capacity (TLC) would be associated with reduced airway lumen dimensions, whereas increased functional residual capacity (FRC), TLC, and reduced inspiratory capacity (IC)/TLC would be associated with emphysema on CT scan. We examined whether clinical characteristics differed accordingly. ⋯ Gas trapping and hyperexpansion on plethysmography were associated with distinct differences in lung structure and clinical characteristics. Absolute lung volumes should not be considered equivalent in their estimation of hyperinflation and provide insight into the extent of airway and parenchymal abnormalities in COPD.

Longitudinal and Prognostic Evaluation of Mild Traumatic Brain Injury: a 1H-MRS Study.
In the majority of patients with mild traumatic brain injury (mTBI), brain tissue impairment is undetectable by computed tomography and/or structural magnetic resonance imaging. Even in confirmed cases of head injury, conventional neuroimaging methods lack sensitivity in predicting neuropsychological outcomes of patients. The objectives of this study were to (1) cross-sectionally determine deviations in the neurometabolic profile of patients with mTBI from healthy controls at different stages of mTBI using tightly controlled examination windows, and (2) determine associations between acute neurometabolic markers of mTBI and chronic neurocognitive performance. ⋯ Measurements in the thalamus and centrum semiovale (CSV) emerged as the most indicative of injury and were used to predict neurocognitive outcome. The major findings of this study are (1) decreases in Cho/Cre (choline-to-creatine ratio) measured in the thalamus (p=0.042) and CSV (p=0.017) at the late subacute stage of mTBI; (2) positive associations of early subacute Cre measurements in the CSV with chronic ANAM scores measuring performance in delayed (r=0.497, p=0.019) and immediate (r=0.391, p=0.072) code substitution. These findings show that metabolic measurements in the thalamus and CSV can potentially serve as diagnostic and prognostic markers of mTBI.
