Prevalence, goals of care and long-term outcomes of patients with life-limiting illness referred to a tertiary ICU
OBJECTIVE: To describe the prevalence, characteristics, long-term outcomes and goals-of-care discussions of patients with objective indicators of life-limiting illnesses (LLIs) referred to the intensive care unit. DESIGN, SETTING AND PATIENTS: A prospective, observational, cohort study of all adult inpatients referred to the ICU by the medical emergency team or by direct referral, during the period 30 August 2012 to 1 February 2013, at a tertiary teaching hospital in Australia. MAIN OUTCOME MEASURES: Mortality, LLIs, discharge destination and documentation on goals of care in medical record. RESULTS: A total of 649 of 1024 patients referred to the ICU had an LLI, and only 34.4% of these patients had goals of care documented. Overall, 49.2% were admitted to the ICU, 48.4% were discharged home, and the 1-year mortality was 35.1%. The most common LLI criteria were heart disease (52.2%), chronic obstructive pulmonary disease (24.8%) and frailty (23.7%). The highest 1-year mortality was associated with pre-hospital residence in a nursing home (64.9%), dementia (63.3%), cancer (60.8%) and frailty (50.6%). Analysis of patients by clinical trajectory showed that 1-year mortality was significantly higher for patients with cancer (59.6%), combined organ failure and frailty (47.3%), frailty (43.8%) and organ failure (23.6%), compared with patients with no LLI (P < 0.0001). CONCLUSIONS: A high proportion of patients referred to the ICU have an LLI, and this is associated with prolonged hospital length of stay and a high 1-year mortality, and only one-quarter have documented discussions on goals of care. Patients with cancer-related and frailty-related LLIs have the worst survival trajectories

Dynamical inversion of the energy landscape promotes non-equilibrium self-assembly of binary mixtures
When driven out of equilibrium, many diverse systems can form complex spatial and dynamical patterns, even in the absence of attractive interactions. Using kinetic Monte Carlo simulations, we investigate the phase behavior of a binary system of particles of dissimilar size confined between semiflexible planar surfaces, in which the nanoconfinement introduces a non-local coupling between particles, which we model as an activation energy barrier to diffusion that decreases with the local fraction of the larger particle. The system autonomously reaches a cyclical non-equilibrium state characterized by the formation and dissolution of metastable micelle-like clusters with the small particles in the core and the large ones in the surrounding corona. The power spectrum of the fluctuations in the aggregation number exhibits 1/
noise reminiscent of self-organized critical systems. We suggest that the dynamical metastability of the micellar structures arises from an inversion of the energy landscape, in which the relaxation dynamics of one of the species induces a metastable phase for the other species

Herbal Medicines for the Treatment of Active Ulcerative Colitis: A Systematic Review and Meta-Analysis.
Herbal medicines are used by patients with IBD despite limited evidence. We present a systematic review and meta-analysis of randomized controlled trials (RCTs) investigating treatment with herbal medicines in active ulcerative colitis (UC). A search query designed by a library informationist was used to identify potential articles for inclusion. Articles were screened and data were extracted by at least two investigators. Outcomes of interest included clinical response, clinical remission, endoscopic response, endoscopic remission, and safety. We identified 28 RCTs for 18 herbs. In pooled analyses, when compared with placebo, clinical response rates were significantly higher for Indigo naturalis (IN) (RR 3.70, 95% CI 1.97-6.95), but not for Curcuma longa (CL) (RR 1.60, 95% CI 0.99-2.58) or Andrographis paniculata (AP) (RR 0.95, 95% CI 0.71-1.26). There was a significantly higher rate of clinical remission for CL (RR 2.58, 95% CI 1.18-5.63), but not for AP (RR 1.31, 95% CI 0.86-2.01). Higher rates of endoscopic response (RR 1.56, 95% CI 1.08-2.26) and remission (RR 19.37, 95% CI 2.71-138.42) were significant for CL. CL has evidence supporting its use as an adjuvant therapy in active UC. Research with larger scale and well-designed RCTs, manufacturing regulations, and education are needed

Healthy families: study protocol for a randomized controlled trial of a screening, brief intervention, and referral to treatment intervention for caregivers to reduce secondhand smoke exposure among pediatric emergency patients
Background: Involuntary exposure to secondhand smoke (SHSe) is an important cause of morbidity in children who present to the pediatric emergency department (PED) and urgent care (UC). SHSe interventions delivered in the PED and UC would benefit both the smoker and child, but there have been no large trials testing the efficacy of such interventions. The Healthy Families program is the first randomized controlled trial to test whether a screening, brief intervention, and referral to treatment (SBIRT) intervention delivered in the PED and UC will be effective in decreasing SHSe in children and increasing cessation in smokers. Methods/design: This trial uses a randomized, two-group design in which caregiver-smokers of children 0-17 years old are recruited from the PED and UC. Eligible caregiver-smokers are randomized to either the: 1) SBIRT Condition with face-to-face, tailored counseling that focuses on the child's illness, the importance of reducing child SHSe, caregiver smoking cessation, and the option to receive nicotine replacement therapy; or 2) Healthy Habits Control Condition which includes face-to-face, tailored attention control "5-2-1-0" counseling that focuses on improving the child's health. Dyadic assessments are conducted in-person at baseline, and via email, phone, or in-person at 6-weeks and 6-months. The primary outcomes are biochemically-verified, 7-day point prevalence and prolonged smoking abstinence. Secondary outcomes are cigarettes smoked per week, 24 h quit attempts, and biochemically validated child SHSe at each time point. The costs of this intervention will also be analyzed. Discussion: This study will test an innovative, multilevel intervention designed to reduce child SHSe and increase smoking cessation in caregivers. If effective and routinely used, this SBIRT model could reach at least one million smokers a year in the U.S., resulting in significant reductions in caregivers' tobacco use, SHSe-related pediatric illness, and healthcare costs in this population of children.National Institutes of Health, National Institute for Child Health and Human Development [R01HD083354]open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
