Objective. To evaluate the usefulness of the Frailty Index (FI) as a prognostic indicator of adverse outcomes in geriatric trauma patients,. Design. Prospective cohort study. Setting and participants. Geriatric (aged 65 and over) trauma patients admitted to inpatient units at a Level 1 trauma center in Arizona were enrolled. Patients were excluded if they were intubated/nonresponsive with no family members present or transferred from another institution (eg, skilled nursing facility). The following categories of data were collected: (a) patient demographics, (b) type and mechanism of injury, (c) vital signs (eg, Glasgow coma scale score, systolic blood pressure, heart rate, body temperature), (d) need for operative intervention, (e) in-hospital complications, (f) hospital and intensive care unit (ICU) lengths of stay, and (g) discharge disposition. Patients or, in the case of nonresponsive patients, their closest relative, responded to the 50-item Frailty Index questionnaire, which includes questions regarding age, comorbid conditions, medications, activities of daily living (ADLs), social activities, mood, and nutrition. FI score ranges from 0 (non-frail) to 1 (frail), with an FI of 0.25 or more indicative of frailty based on established guidelines. Patients were categorized as frail or non-frail according to their FI scores and were followed during the course of their hospitalization. Main outcome measure. The primary outcome measure was in-hospital complications. In-hospital complications included myocardial infarction, cardiopulmonary arrest, pneumonia, pulmonary embolism, sepsis, urinary tract infection, deep venous thrombosis, disseminated intravascular coagulation, renal insufficiency, and reoperation. The secondary outcome measure was adverse discharge disposition, which was defined as death during the course of hospitalization or discharge to a skilled nursing facility. Main results. The sample consisted of 250 patients with a mean age of 77.9 years. Among these, 44.0% were considered frail. Patients with frailty were more likely to have a higher Injury Severity Score (P = 0.04) and a higher mean FI (P = 0.01) than those without frailty. There were no statistically significant differences with respect to age (P = 0.21), mechanism of injury (P = 0.09), systolic blood pressure (P = 0.30), or Glasgow Coma Scale score (P = 0.91) between the groups. Patients with frailty were more likely to develop in-hospital complications (37.3% vs 21.4%, P = 0.001) than those without frailty. Among these complications, pneumonia and urinary tract infection were the most common. There were no differences in the rate of reoperation (P = 0.54) between the 2 groups. An FI of 0.25 or higher was associated with the development of in-hospital complications (P = 0.001) even after adjusting for age, systolic blood pressure, heart rate, and Injury Severity Score. Frail patients had longer hospital length of stay (P = 0.01) and ICU length of stay (P = 0.01), and were more likely to have adverse discharge disposition (37.3% vs. 12.9%, P = 0.001). All patients who died during the course of hospitalization (n = 5) were considered frail. Frailty was also found to be a predictor of adverse discharge disposition (P = 0.001) after adjustment for age, male sex, Injury Severity Score, and mechanism of injury. Conclusion. The FI is effective in identifying geriatric trauma patients, who are vulnerable to poor health outcomes

OBJECTIVE: To explore the characteristics, motivations, ideologies, experience and perspectives of experienced medical humanitarian workers. DESIGN: We applied a qualitative descriptive approach and conducted in-depth semistructured interviews, containing open-ended questions with directing probes, with 44 experienced international medical aid workers from a wide range of humanitarian organisations. Interviews were coded and analysed, and themes were developed. SETTING: International non-governmental organisations (INGOs) and United Nations (UN). RESULTS: 61% of participants were female; mean age was 41.8 years with an average of 11.8 years of humanitarian work experience with diverse major INGOs. Significant core themes included: population's rights to assistance, altruism and solidarity as motives; self-identification with the mission and directives of INGOs; shared personal and professional morals fostering collegiality; accountability towards beneficiaries in areas of programme planning and funding; burnout and emotional burdens; uncertainties in job safety and security; and uneasiness over changing humanitarian principles with increasing professionalisation of aid and shrinking humanitarian access. While dissatisfied with overall aid operations, participants were generally satisfied with their work and believed that they were well-received by, and had strong relationships with, intended beneficiaries. CONCLUSIONS: Despite regular use of language and ideology of rights, solidarity and concepts of accountability, tension exists between the philosophy and practical incorporation of accountability into operations. To maintain a humanitarian corps and improve aid worker retention, strategies are needed regarding management of psychosocial stresses, proactively addressing militarisation and neo-humanitarianism, and nurturing individuals' and organisations' growth with emphasis on humanitarian principles and ethical practices, and a culture of internal debate, reflection and reform.

BACKGROUND: Childhood obesity remains a prominent public health problem. Walkable built environments may prevent excess weight gain. OBJECTIVES: We examined the association of walkable built environment characteristics with body mass index (BMI) z-score among a large sample of children and adolescents. METHODS: We used geocoded residential address data from electronic health records of 49,770 children and adolescents 4 to < 19 years of age seen at the 14 pediatric practices of Harvard Vanguard Medical Associates from August 2011 through August 2012. We used eight geographic information system (GIS) variables to characterize walkable built environments. Outcomes were BMI z-score at the most recent visit and BMI z-score change from the earliest available (2008-2011) to the most recent (2011-2012) visit. Multivariable models were adjusted for child age, sex, race/ethnicity, and neighborhood median household income. RESULTS: In multivariable cross-sectional models, living in closer proximity to recreational open space was associated with lower BMI z-score. For example, children who lived in closest proximity (quartile 1) to the nearest recreational open space had a lower BMI z-score (beta = -0.06; 95% CI: -0.08, -0.03) compared with those living farthest away (quartile 4; reference). Living in neighborhoods with fewer recreational open spaces and less residential density, traffic density, sidewalk completeness, and intersection density were associated with higher cross-sectional BMI z-score and with an increase in BMI z-score over time. CONCLUSIONS: Overall, built environment characteristics that may increase walkability were associated with lower BMI z-scores in a large sample of children. Modifying existing built environments to make them more walkable may reduce childhood obesity.

A comparative trial using a repeated-measures design was designed to evaluate the feasibility and outcomes of the Family-Centered Function-Focused-Care (Fam-FFC) intervention, which is intended to promote functional recovery in hospitalized older adults. A family-centered resource nurse and a facility champion implemented a three-component intervention (environmental assessment and modification, staff education, individual and family education and partnership in care planning with follow-up after hospitalization for an acute illness). Control units were exposed to function-focused-care education only. Ninety-seven dyads of medical patients aged 65 and older and family caregivers (FCGs) were recruited from three medical units of a community teaching hospital. Fifty-three percent of patients were female, 89% were white, 51% were married, and 40% were widowed, and they had a mean age of 80.8 +/- 7.5. Seventy-eight percent of FCGs were married, 34% were daughters, 31% were female spouses or partners, and 38% were aged 46 to 65. Patient outcomes included functional outcomes (activities of daily living (ADLs), walking performance, gait, balance) and delirium severity and duration. FCG outcomes included preparedness for caregiving, anxiety, depression, role strain, and mutuality. The intervention group demonstrated less severity and shorter duration of delirium and better ADL and walking performance but not better gait and balance performance than the control group. FCGs who participated in Fam-FFC showed a significant increase in preparedness for caregiving and a decrease in anxiety and depression from admission to 2 months after discharge but no significant differences in strain or quality of the relationship with the care recipient from FCGs in the control group. Fam-FFC is feasible and has the potential to improve outcomes for hospitalized older adults and their caregivers.

BACKGROUND: Persons with a mental health diagnosis have high rates of tobacco use and face numerous barriers to cessation including high levels of nicotine dependence, low rates of tobacco treatment referrals from mental health providers, and limited availability of tobacco treatment targeted to their needs. This manuscript describes the rationale and methods of a clinical trial with the following aims: 1) Compare the reach and efficacy of a proactive telephone-based tobacco cessation program for Veterans Health Administration (VHA) mental health clinic patients to VHA usual care and 2) Model longitudinal associations between baseline patient characteristics and long-term abstinence. METHODS/DESIGN: We will use the electronic medical record to identify patients across four VHA healthcare facilities who have a clinical reminder code indicating current tobacco use in the past six months and who have had a mental health clinic visit in the past 12 months. We will send each patient an introductory letter and baseline survey. Survey respondents (N = 3840) will be randomized in a 1:1 fashion to intervention or control. Control participants will receive VHA usual care. Intervention participants will receive proactive motivational telephone outreach to offer tobacco treatment. Intervention participants interested in treatment will receive eight weeks of nicotine replacement therapy plus eight sessions of specialized telephone counseling over two months, followed by monthly maintenance counseling for four months. We will conduct telephone surveys with participants at six and 12 months to assess study outcomes. We will collect a mailed saliva sample from patients reporting 7-day abstinence on the telephone surveys. The primary outcome will be cotinine-validated abstinence at 12-month follow-up. DISCUSSION: Mental health patients are a high-risk smoking population with significant barriers to cessation. This study will evaluate the efficacy of a program that proactively reaches out to smokers with a mental health treatment history to engage them into telephone cessation counseling targeted to the needs of mental health patients. TRIAL REGISTRATION: Clinicaltrials.gov: NCT01737281 (registered November 5, 2012).

SUMMARY Alzheimer's disease (AD) has high economic impact and places significant burden on patients, caregivers, providers and healthcare delivery systems, fostering the need for an evaluation of alternative approaches to healthcare delivery for dementia. Collaborative care models are team-based, multicomponent interventions that provide a pragmatic strategy to deliver integrated healthcare to patients and families across a wide range of populations and clinical settings. Healthcare reform and national plans for AD goals to integrate quality care, health promotion and preventive services, and reduce the impact of disease on patients and families reinforcing the need for a system-level evaluation of how to best meet the needs of patients and families. We review collaborative care models for AD and offer evidence for improved patient- and family-centered outcomes, quality indicators of care and potential cost savings.

OBJECTIVE: To evaluate whether genetic correction using the genetic variants prostate-specific antigen (PSA)-single nucleotide polymorphisms (SNPs) could reduce potentially unnecessary and/or delayed biopsies in African-American men. SUBJECTS AND METHODS: We compared the genotypes of four PSA-SNPs between 964 Caucasian and 363 African-American men without known prostate cancer (PCa). We adjusted the PSA values based on an individual's PSA-SNP carrier status, and calculated the percentage of men that would meet commonly used PSA thresholds for biopsy (>/=2.5 or >/=4.0 ng/mL) before and after genetic correction. Potentially unnecessary and delayed biopsies were defined as those men who were below and above the biopsy threshold after genetic correction, respectively. RESULTS: Overall, 349 (96.1%) and 354 (97.5%) African-American men had measured PSA levels <2.5 and <4.0 ng/mL. Genetic correction in African-American men did not avoid any potentially unnecessary biopsies, but resulted in a significant (P < 0.001) reduction in potentially delayed biopsies by 2.5% and 3.9%, based on the biopsy threshold level. CONCLUSIONS: There are significant differences in the influence of the PSA-SNPs between African-American and Caucasian men without known PCa, as genetic correction resulted in an increased proportion of African-American men crossing the threshold for biopsy. These results raise the question of whether genetic differences in PSA might contribute to delayed PCa diagnosis in African-American men.

Large cell neuroendocrine carcinoma of the prostate (LCNEC), de novo in particular, is an extremely rare entity that has only been described in the literature in case reports. Historically, the majority of the cases of LCNEC reported in the literature represent typical prostatic adenocarcinomas that transformed after long standing androgen deprivation therapy (ADT). These cases were admixed with histological areas of usual adenocarcinoma and showed hybrid features of both neuroendocrine and usual adenocarcinoma. Here we present a case of an LCNEC without admixed areas of usual prostatic adenocarcinoma arising de novo in a patient without prior history of hormonal therapy. The tumor also shows morphologic evidence of neuroendocrine differentiation; composed of large sheets and nests of cells with moderate amphophilic cytoplasm with peripheral palisading, and vesicular clumpy chromatin with prominent nucleoli. The carcinoma's prostatic origin is indicated by positive immunohistochemical staining for PSA, PAP, PSMA, racemase, and Nkx3.1. Diffusely positive staining for chromogranin and synaptophysin, as well as the presence of secretory granules in the cytoplasm of the tumor cells demonstrated by electron microscopy supports the NE differentiation. NE prostate cancer usually does not express AR and is refractory to ADT therapy while AR and ERG are positive in this case. In summary, we report a de novo LCNEC of the prostate with review of literature, in particular, clinical implications.
