Programmatic Costs of the Telehealth Ostomy Self-Management Training: An Application of Time-Driven Activity-Based Costing

OBJECTIVES

Programmatic cost assessment of novel clinical interventions can inform their widespread dissemination and implementation. This study aimed to determine the programmatic costs of a telehealth Ostomy Self-Management Training (OSMT) intervention for cancer survivors using Time-Driven Activity-Based Costing (TDABC) methodology.

METHODS

We demonstrated a step-by-step application of TDABC based on a process map with core OSMT intervention activities and associated procedures and determined resource use and costs, per unit procedure. We also assessed per-patient costs from a payer perspective and provided estimates of total hours and costs by personnel, activity, and procedure.

RESULTS

The per-patient cost of the OSMT was $1758. Personnel time accounted for 91% of the total cost. Site supervisor and information technology technician time were the most expensive personnel resources. Telehealth technical and communication equipment accounted for 8% of the total cost. Intervention coordination and monitoring efforts represented most of the total time cost (62%), followed by the intervention delivery (35%). The procedures with the highest cost were communication via phone or virtual meetings (24%), email exchanges (18%), and telehealth session delivery (18%).

CONCLUSIONS

Future efforts to replicate, disseminate, and implement the OSMT intervention should anticipate funding for nonclinical components of the intervention, including coordination and monitoring, and consider how these activities can be performed most efficiently. For institutions without established telemedicine programs, selection of videoconferencing platforms and adequate staffing for participant technical support should be considered. Our step-by-step application of TDABC serves as a case study demonstrating how interventionists can gather data on resource use and costs of intervention activities concurrently with their collection of trial data.

The role of staffing and classroom characteristics on preschool teachers' use of one-to-one intervention with children with autism

LAY ABSTRACT

For preschool children with autism, individual (one-to-one) behavioral interventions are among the best-tested treatments. However, they are rarely used in special education preschools. We observed formally and informally delivered one-to-one behavioral interventions use by classroom staff (n = 51) in 12 classrooms across three special education preschools for children with autism, aged 3-6 years, in a major US city. We estimated the associations between one-to-one intervention use and classroom characteristics including staff-student ratio, professional role composition, and frequency of challenging child behaviors. As a whole, the factors we examined were considerably important for both formally and informally delivered one-to-one interventions. The number of individually assigned personal care aides in the classroom was negatively associated with the use of formally delivered one-to-one intervention. Classroom challenging behavior was positively associated with use of formally delivered one-to-one interventions. Interventionist's professional roles and the number of children in the class were most important for the use of informally delivered interventions. Staff training, clarifying professional roles, setting performance expectations for personal care aides and other classroom team members, and reducing class size may represent promising implementation targets. Findings suggest caution around task-shifting policies that transfer clinical functions from more highly trained to less highly trained staff.

A pragmatic method for costing implementation strategies using time-driven activity-based costing

BACKGROUND

Implementation strategies increase the adoption of evidence-based practices, but they require resources. Although information about implementation costs is critical for decision-makers with budget constraints, cost information is not typically reported in the literature. This is at least partly due to a need for clearly defined, standardized costing methods that can be integrated into implementation effectiveness evaluation efforts.

METHODS

We present a pragmatic approach to systematically estimating detailed, specific resource use and costs of implementation strategies that combine time-driven activity-based costing (TDABC), a business accounting method based on process mapping and known for its practicality, with a leading implementation science framework developed by Proctor and colleagues, which guides specification and reporting of implementation strategies. We illustrate the application of this method using a case study with synthetic data.

RESULTS

This step-by-step method produces a clear map of the implementation process by specifying the names, actions, actors, and temporality of each implementation strategy; determining the frequency and duration of each action associated with individual strategies; and assigning a dollar value to the resources that each action consumes. The method provides transparent and granular cost estimation, allowing a cost comparison of different implementation strategies. The resulting data allow researchers and stakeholders to understand how specific components of an implementation strategy influence its overall cost.

CONCLUSION

TDABC can serve as a pragmatic method for estimating resource use and costs associated with distinct implementation strategies and their individual components. Our use of the Proctor framework for the process mapping stage of the TDABC provides a way to incorporate cost estimation into implementation evaluation and may reduce the burden associated with economic evaluations in implementation science.

Victimization and Perpetration of Violence Involving Persons With Mood and Other Psychiatric Disorders and Their Relatives

OBJECTIVE

This study aimed to examine the rate at which persons with psychiatric disorders were victims of violence by reference relatives and the extent to which victimization and perpetration co-occurred in this population.

METHODS

A total of 523 adults with a psychiatric disorder completed an online survey. Chi-square and Fisher's exact tests were computed.

RESULTS

Since first diagnosis, 25% and 26% of respondents reported having been a victim of violence by reference relatives and having committed violence toward reference relatives, respectively. Thirteen percent of respondents reported having been a victim of violence by reference relatives, and 12% reported having committed violence toward reference relatives in the past 6 months. Victimization and perpetration often co-occurred.

CONCLUSIONS

The risk of victimization and perpetration of family violence among persons with psychiatric disorders should be acknowledged. Assessing for risk of perpetrating family violence and intervening in such cases should entail assessing for and/or addressing victimization, and vice versa.

Examination of Three Concentrated Black Raspberry Juices for Authenticity

Gradient elution, paper, and thin layer chromatography were used to detect adulteration in black raspberry juice concentrates. Results show that a combination of gradient elution chromatography plus thin layer chromatography of the anthocyanin isolates provide definite indications of the purity of concentrated fruit juices.

Trajectories of Evidence Based Treatment for School Children with Autism: What's the Right Level for the Implementation?

Evidence-based practices (EBP) for children with autism are under-used in special-education schools. No research compared child-level versus teacher-level influences on EBP use, which could guide implementation strategies. We derived longitudinal profiles of EBP receipt by children (N = 234) in 69 autism-support classrooms, over an academic year. We compared overall impacts of child-level and teacher-level factors on profile membership. Most children received little EBP throughout the year; however substantial subgroups received increasing, and decreasing, doses of EBP. Child-level and teacher-level factors contributed about equally to profile membership. Children's autism symptoms and verbal ability, teachers' EBP skills, training/experience, classroom support, class size, and implementation leadership climate predicted profile membership. Early identification of treatment profiles could facilitate targeted implementation strategies increasing EBP use.

Brief Report: Service Use and Associated Expenditures Among Adolescents with Autism Spectrum Disorder Transitioning to Adulthood

This study compared Medicaid service utilization and expenditures among adolescents with autism spectrum disorder (ASD) to adolescents with intellectual disability (ID) as they aged into adulthood. Medicaid Analytic eXtract (MAX) data was used to identify a national cohort. Winsorization was utilized to control for expenditure outliers. A greater proportion of adolescents with ASD utilized most services. Decreases in the use of key services, including psychiatric outpatient services, were observed for both groups. Changes in medical services, such as increases in inpatient and long term care services, among the ASD cohort suggest medical needs of adolescents with ASD change as they age. Information remains lacking on changing ASD symptom presentation during the transition to adolescence.

Transition-Age Medicaid Coverage for Adolescents With Autism and Adolescents With Intellectual Disability

Although the majority of adolescents with autism spectrum disorder (ASD) rely on healthcare coverage through Medicaid during their transition into adulthood, little is known about their continuing eligibility. This study used Medicaid Analytic Extract (MAX) data to examine Medicaid coverage in a national sample using a cohort of adolescents with ASD ( n = 4,179) and a like-aged cohort with intellectual disability (ID, n = 21,844) over 5 years using survival analysis and Cox regression models. More than 1 in 4 adolescents with ASD lost coverage and fewer than half subsequently regained it. They were more likely to disenroll than adolescents with ID. Similarities in overall patterns among the 2 groups suggest that the experience of adolescents with ASD was characteristic of more general aspects of behavioral health coverage and indicate the need for programmatic reforms.

Adverse events in veterans affairs inpatient psychiatric units: Staff perspectives on contributing and protective factors

OBJECTIVES

This study sought to identify risk factors and protective factors in hospital-based mental health settings in the Veterans Health Administration (VHA), with the goal of informing interventions to improve care of persons with serious mental illness.

METHODS

Twenty key informants from a stratified sample of 7 VHA inpatient psychiatric units were interviewed to gain their insights on causes of patient safety events and the factors that constrain or facilitate patient safety efforts.

RESULTS

Respondents identified threats to patient safety at the system-, provider-, and patient-levels. Protective factors that, when in place, made patient safety events less likely to occur included: promoting a culture of safety; advocating for patient-centeredness; and engaging administrators and organizational leadership to champion these changes.

CONCLUSIONS

Findings highlight the impact of systems-level policies and procedures on safety in inpatient mental health care. Engaging all stakeholders, including patients, in patient safety efforts and establishing a culture of safety will help improve the quality of inpatient psychiatric care. Successful implementation of changes require the knowledge of local experts most closely involved in patient care, as well as support and buy-in from organizational leadership.

When Too Much Is Enough: Pediatric Cyproheptadine Overdose with Confirmatory Level

Cyproheptadine is an H-1 antihistamine with anticholinergic and antiserotonergic effects. Cyproheptadine’s most common use has been in the management cold-induced urticaria. It is often used in primary care for its side effect of appetite stimulation. Recently there has been increasing interest in its use in the treatment of drug-induced serotonin syndrome. Cyproheptadine overdose is uncommonly reported in the medical literature. We report the rare case of a pediatric cyproheptadine overdose with a confirmatory cyproheptadine level.

A mixed methods study of individual and organizational factors that affect implementation of interventions for children with autism in public schools

Background

The significant lifelong impairments associated with autism spectrum disorder (ASD), combined with the growing number of children diagnosed with ASD, have created urgency in improving school-based quality of care. Although many interventions have shown efficacy in university-based research, few have been effectively implemented and sustained in schools, the primary setting in which children with ASD receive services. Individual- and organizational-level factors have been shown to predict the implementation of evidence-based interventions (EBIs) for the prevention and treatment of other mental disorders in schools, and may be potential targets for implementation strategies in the successful use of autism EBIs in schools. The purpose of this study is to examine the individual- and organizational-level factors associated with the implementation of EBIs for children with ASD in public schools.

Methods

We will apply the Domitrovich and colleagues (2008) framework that examines the influence of contextual factors (i.e., individual- and organizational-level factors) on intervention implementation in schools. We utilize mixed methods to quantitatively test whether the factors identified in the Domitrovich and colleagues (2008) framework are associated with the implementation of autism EBIs, and use qualitative methods to provide a more comprehensive understanding of the factors associated with successful implementation and sustainment of these interventions with the goal of tailoring implementation strategies.

Discussion

The results of this study will provide an in-depth understanding of individual- and organizational-level factors that influence the successful implementation of EBIs for children with ASD in public schools. These data will inform potential implementation targets and tailoring of strategies that will help schools overcome barriers to implementation and ultimately improve the services and outcomes for children with ASD.

Predictors of community therapists' use of therapy techniques in a large public mental health system

IMPORTANCE

Few studies have examined the effects of individual and organizational characteristics on the use of evidence-based practices in mental health care. Improved understanding of these factors could guide future implementation efforts to ensure effective adoption, implementation, and sustainment of evidence-based practices.

OBJECTIVE

To estimate the relative contribution of individual and organizational factors on therapist self-reported use of cognitive-behavioral, family, and psychodynamic therapy techniques within the context of a large-scale effort to increase use of evidence-based practices in an urban public mental health system serving youth and families.

DESIGN, SETTING, AND PARTICIPANTS

In this observational, cross-sectional study of 23 organizations, data were collected from March 1 through July 25, 2013. We used purposive sampling to recruit the 29 largest child-serving agencies, which together serve approximately 80% of youth receiving publically funded mental health care. The final sample included 19 agencies with 23 sites, 130 therapists, 36 supervisors, and 22 executive administrators.

MAIN OUTCOMES AND MEASURES

Therapist self-reported use of cognitive-behavioral, family, and psychodynamic therapy techniques, as measured by the Therapist Procedures Checklist-Family Revised.

RESULTS

Individual factors accounted for the following percentages of the overall variation: cognitive-behavioral therapy techniques, 16%; family therapy techniques, 7%; and psychodynamic therapy techniques, 20%. Organizational factors accounted for the following percentages of the overall variation: cognitive-behavioral therapy techniques, 23%; family therapy techniques, 19%; and psychodynamic therapy techniques, 7%. Older therapists and therapists with more open attitudes were more likely to endorse use of cognitive-behavioral therapy techniques, as were those in organizations that had spent fewer years participating in evidence-based practice initiatives, had more resistant cultures, and had more functional climates. Women were more likely to endorse use of family therapy techniques, as were those in organizations employing more fee-for-service staff and with more stressful climates. Therapists with more divergent attitudes and less knowledge about evidence-based practices were more likely to use psychodynamic therapy techniques.

CONCLUSIONS AND RELEVANCE

This study suggests that individual and organizational factors are important in explaining therapist behavior and use of evidence-based practices, but the relative importance varies by therapeutic technique.

Are inner context factors related to implementation outcomes in cognitive-behavioral therapy for youth anxiety?

Among the challenges facing the mental health field are the dissemination and implementation of evidence-based practices. The present study investigated the relationships between inner context variables (i.e., adopter characteristics and individual perceptions of intra-organizational factors) and two implementation outcomes-independently rated therapist fidelity on a performance-based role-play (i.e., adherence and skill) and self-reported penetration of cognitive behavioral therapy for youth anxiety following training. A significant relationship was found between inner context variables and fidelity. Specifically, adopter characteristics were associated with adherence and skill; individual perceptions of intra-organizational factors were associated with adherence. Inner context variables were not associated with penetration. Future directions are discussed.

The role of frataxin in fission yeast iron metabolism: implications for Friedreich's ataxia

BACKGROUND

The neurodegenerative disease Friedreich's ataxia is the result of frataxin deficiency. Frataxin is a mitochondrial protein involved in iron-sulfur cluster (Fe-S) cofactor biogenesis, but its functional role in this pathway is debated. This is due to the interconnectivity of iron metabolic and oxidative stress response pathways that make distinguishing primary effects of frataxin deficiency challenging. Since Fe-S cluster assembly is conserved, frataxin overexpression phenotypes in a simple eukaryotic organism will provide additional insight into frataxin function.

METHODS

The Schizosaccharomyces pombe frataxin homologue (fxn1) was overexpressed from a plasmid under a thiamine repressible promoter. The S. pombe transformants were characterized at several expression strengths for cellular growth, mitochondrial organization, iron levels, oxidative stress, and activities of Fe-S cluster containing enzymes.

RESULTS

Observed phenotypes were dependent on the amount of Fxn1 overexpression. High Fxn1 overexpression severely inhibited S. pombe growth, impaired mitochondrial membrane integrity and cellular respiration, and led to Fxn1 aggregation. Cellular iron accumulation was observed at moderate Fxn1 overexpression but was most pronounced at high levels of Fxn1. All levels of Fxn1 overexpression up-regulated oxidative stress defense and mitochondrial Fe-S cluster containing enzyme activities.

CONCLUSIONS

Despite the presence of oxidative stress and accumulated iron, activation of Fe-S cluster enzymes was common to all levels of Fxn1 overexpression; therefore, Fxn1 may regulate the efficiency of Fe-S cluster biogenesis in S. pombe.

GENERAL SIGNIFICANCE

We provide evidence that suggests that dysregulated Fe-S cluster biogenesis is a primary effect of both frataxin overexpression and deficiency as in Friedreich's ataxia.

Policy to implementation: evidence-based practice in community mental health--study protocol

Background

Evidence-based treatments (EBTs) are not widely available in community mental health settings. In response to the call for implementation of evidence-based treatments in the United States, states and counties have mandated behavioral health reform through policies and other initiatives. Evaluations of the impact of these policies on implementation are rare. A systems transformation about to occur in Philadelphia, Pennsylvania, offers an important opportunity to prospectively study implementation in response to a policy mandate.

Methods/design

Using a prospective sequential mixed-methods design, with observations at multiple points in time, we will investigate the responses of staff from 30 community mental health clinics to a policy from the Department of Behavioral Health encouraging and incentivizing providers to implement evidence-based treatments to treat youth with mental health problems. Study participants will be 30 executive directors, 30 clinical directors, and 240 therapists. Data will be collected prior to the policy implementation, and then at two and four years following policy implementation. Quantitative data will include measures of intervention implementation and potential moderators of implementation (i.e., organizational- and leader-level variables) and will be collected from executive directors, clinical directors, and therapists. Measures include self-reported therapist fidelity to evidence-based treatment techniques as measured by the Therapist Procedures Checklist-Revised, organizational variables as measured by the Organizational Social Context Measurement System and the Implementation Climate Assessment, leader variables as measured by the Multifactor Leadership Questionnaire, attitudes towards EBTs as measured by the Evidence-Based Practice Attitude Scale, and knowledge of EBTs as measured by the Knowledge of Evidence- Based Services Questionnaire. Qualitative data will include semi-structured interviews with a subset of the sample to assess the implementation experience of high-, average-, and low-performing agencies. Mixed methods will be integrated through comparing and contrasting results from the two methods for each of the primary hypotheses in this study.

Discussion

Findings from the proposed research will inform both future policy mandates around implementation and the support required for the success of these policies, with the ultimate goal of improving the quality of treatment provided to youth in the public sector.

Analysis and validation of putative substances involved in fatal poisonings

Each year, poison control centers throughout the United States respond to over 4 million calls for help in treating individuals exposed to toxic substances. Although most cases develop no or minimal clinical effects, a small proportion of patients who receive medical care for overdoses with poison center consultation expire. When such cases are investigated by a medical examiner, the postmortem toxicology results may show substances other than those considered in the consultation with the poison center. We sought to determine the characteristics of discordance in fatal cases between the toxic substances reported to a regional poison control center and postmortem toxicology results. We conducted a retrospective study of the New Jersey regional poison control center records of all fatal cases between the years 1986 and 2006. Substances reported as putative agents to the poison center were compared to the postmortem toxicology results obtained by the medical examiner. The frequencies and characteristics surrounding discordance were examined. Of the 708 fatal cases reported to our poison center within the study period, complete postmortem toxicological evaluations were available for 206 (29.0%). Comparison of putative agents between information obtained by history and at postmortem evaluation showed discordance in 41 (19.9%). In a substantial number of fatal cases receiving poison center consultation, substances were found at the time of postmortem examination that were not considered in the poison center consultation. The reasons for this discordance may include a lack of thorough history-taking or a cognitive bias to the substances initially reported.

Disruption of PF4/H multimolecular complex formation with a minimally anticoagulant heparin (ODSH)

Recent studies have shown that ultra-large complexes (ULCs) of platelet factor 4 (PF4) and heparin (H) play an essential role in the pathogenesis of heparin-induced thrombocytopenia (HIT), an immune-mediated disorder caused by PF4/H antibodies. Because antigenic PF4/H ULCs assemble through non-specific electrostatic interactions, we reasoned that disruption of charge-based interactions can modulate the immune response to antigen. We tested a minimally anticoagulant compound (2-O, 3-O desulfated heparin, ODSH) with preserved charge to disrupt PF4/H complex formation and immunogenicity. We show that ODSH disrupts complexes when added to pre-formed PF4/H ULCs and prevents ULC formation when incubated simultaneously with PF4 and UFH. In other studies, we show that excess ODSH reduces HIT antibody (Ab) binding in immunoassays and that PF4/ODSH complexes do not cross-react with HIT Abs. When ODSH and unfractionated heparin (UFH) are mixed at equimolar concentrations, we show that there is a negligible effect on amount of protamine required for heparin neutralisation and reduced immunogenicity of PF4/UFH in the presence of ODSH. Taken together, these studies suggest that ODSH can be used concurrently with UFH to disrupt PF4/H charge interactions and provides a novel strategy to reduce antibody mediated complications in HIT.

Get screened: a pragmatic randomized controlled trial to increase mammography and colorectal cancer screening in a large, safety net practice

Background

Most randomized controlled trials of interventions designed to promote cancer screening, particularly those targeting poor and minority patients, enroll selected patients. Relatively little is known about the benefits of these interventions among unselected patients.

Methods/Design

"Get Screened" is an American Cancer Society-sponsored randomized controlled trial designed to promote mammography and colorectal cancer screening in a primary care practice serving low-income patients. Eligible patients who are past due for mammography or colorectal cancer screening are entered into a tracking registry and randomly assigned to early or delayed intervention. This 6-month intervention is multimodal, involving patient prompts, clinician prompts, and outreach. At the time of the patient visit, eligible patients receive a low-literacy patient education tool. At the same time, clinicians receive a prompt to remind them to order the test and, when appropriate, a tool designed to simplify colorectal cancer screening decision-making. Patient outreach consists of personalized letters, automated telephone reminders, assistance with scheduling, and linkage of uninsured patients to the local National Breast and Cervical Cancer Early Detection program. Interventions are repeated for patients who fail to respond to early interventions. We will compare rates of screening between randomized groups, as well as planned secondary analyses of minority patients and uninsured patients. Data from the pilot phase show that this multimodal intervention triples rates of cancer screening (adjusted odds ratio 3.63; 95% CI 2.35 - 5.61).

Discussion

This study protocol is designed to assess a multimodal approach to promotion of breast and colorectal cancer screening among underserved patients. We hypothesize that a multimodal approach will significantly improve cancer screening rates.

Methadone and buprenorphine toxicity in children

Recent years have seen very large increases in the prescribing of methadone and buprenorphine formulations for treatment of opioid addiction as well as the increasing utilization of methadone for the treatment of chronic pain. Coincident with the rise in the prescribing of these drugs has been a substantial increase in pediatric opioid toxicities and adverse events. This review will address the current state of methadone- and buprenorphine-related adverse events in children in the United States. We will also discuss treatment of opioid toxicity in pediatric populations and make recommendations aimed at reducing these occurrences.

Separation of mycobacterial soluble antigens by isoelectric focusing

Ion-exchange chromatography and gel filtration have been reported to yield partial separation of mycobacterial antigens. These procedures were used in combination with isoelectric focusing in an attempt to purify antigens of Mycobacterium tuberculosis strain H37Ra. The fractionating action of isoelectric focusing is dependent upon differences in the isoelectric points of the proteins to be separated. Culture filtrate of M. tuberculosis H37Ra was chromatographed on Sephadex G-200. This resulted in two widely separated peaks. The first peak, presumably containing high-molecular-weight substances, was then fractionated on a diethylaminoethyl Sephadex anion-exchange column. Three peaks were collected, and each was subjected to isoelectric focusing. Each peak was further separated into two or more fractions. The serological reactivity of each fraction was determined by immunodiffusion and immunoelectrophoresis. Sensitized guinea pigs were also skin-tested with the fractions. Two of the fractions contained only a single precipitinogen. One fraction contained two precipitinogens. A fourth fraction contained three precipitinogens and was also the only fraction to display sensitin activity. Four of the fractions were inactive either as precipitinogens or sensitins. The results suggest that the methods described are useful for the separation of mycobacterial antigens.

Effects of a yoga breath intervention alone and in combination with an exposure therapy for post-traumatic stress disorder and depression in survivors of the 2004 South-East Asia tsunami

OBJECTIVE

This study evaluated the effect of a yoga breath program alone and followed by a trauma reduction exposure technique on post-traumatic stress disorder and depression in survivors of the 2004 Asian tsunami.

METHOD

In this non-randomized study, 183 tsunami survivors who scored 50 or above on the Post-traumatic Checklist-17 (PCL-17) were assigned by camps to one of three groups: yoga breath intervention, yoga breath intervention followed by 3-8 h of trauma reduction exposure technique or 6-week wait list. Measures for post-traumatic stress disorder (PCL-17) and depression (BDI-21) were performed at baseline and at 6, 12 and 24 weeks. Data were analyzed using anova and mixed effects regression.

RESULTS

The effect of treatment vs. control was significant at 6 weeks (F(2,178) = 279.616, P < 0.001): mean PCL-17 declined by 42.5 +/- 10.0 SD with yoga breath, 39.2 +/- 17.2 with Yoga breath + exposure and 4.6 +/- 13.2 in the control.

CONCLUSION

Yoga breath-based interventions may help relieve psychological distress following mass disasters.

Perinatal status and help-seeking for intimate partner violence

BACKGROUND

Although there has been much research examining the relationship between pregnancy and abuse, this study is one of the few to investigate whether perinatal status (defined as pregnancy or early postpartum) impacts the help seeking of abused women.

METHODS

We retrospectively reviewed 3 years of prosecutor administrative records, police incident reports, and hospital medical records for a countywide population of adult females (n = 964) assaulted by an intimate partner in 2000. Perinatal and nonperinatal victims were compared using chi-square and a series of logistic regression models, controlling for all demographic and incident-related factors.

RESULTS

Compared with women across the county, abused women were twice as likely to become pregnant (p < 0.001). Perinatal status did not change the rate of help seeking from police (OR 1.1, p = 0.67) or emergency departments (ED) (OR 1.1, p = 0.94), but it did change the pattern of help seeking with higher ED use in the 6 months prior to the assault (p < 0.01) and a trend toward seeking help with fewer injuries (p = 0.10).

CONCLUSIONS

Abused women are more likely to become pregnant. Perinatal status impacts how victims seek help from criminal justice agencies and EDs.

"One end has nothing to do with the other:" patient attitudes regarding help seeking intention for depression in gynecologic and obstetric settings

Many women rely on their obstetrician/gynecologist (OB/GYN) as their primary contact with the health care delivery system. There have been few studies exploring patient views on getting help for depression from these providers. The purpose of this study is to assess help seeking intention for depression and identify beliefs which moderate this intention. Telephone interviews of women following a routine gynecologic visit or in the immediate postpartum period (regarding prenatal care) were used to assess intention to seek help from their providers in a case of depression. For women who lacked this intention, related beliefs were elicited with the open ended question "why not?" Among the 225 women in the study more than half receiving gynecologic care (59%) and nearly a third of women who received prenatal care (29%; p < 0.001) stated they would not seek help from their OB/GYN for depression. Report that a prenatal provider had mentioned depression was associated with help seeking intention for depression but was not independent of confounding variables. Beliefs among women who lacked help seeking intention clustered into two attitude themes: 1) an OB/GYN is the wrong doctor for depression care and 2) OB/GYN is not a good setting for depression care. Many women have attitudes which reduce their intention to seek help for depression from their OB/GYN. Interventions aiming to increase delivery of depression care in these settings should consider these beliefs in their design.

The impact of coercion on services from the perspective of mental health care consumers with co-occurring disorders

OBJECTIVE

Disengagement from services by people with serious mental illnesses continues to be a major challenge for the mental health system. Assertive community treatment combined with Housing First services is an intervention targeted toward consumers whom the system has failed to engage. The processes involved in engaging and maintaining consumers in mental health services play an important role but remain an understudied aspect of the intervention. This study examined the social interaction between consumers and case managers from the perspective of consumers.

METHODS

Seventy service contacts between unique consumer-case manager dyads were sampled. Consumers with co-occurring serious mental illness and substance use disorders completed interviews after each service contact. They provided information on sociodemographic characteristics, service contact characteristics, consumer-provider relationship, utilization of coercive strategies, perceived coercion, and service contact evaluation. Multivariate regression analyses examined the association of consumer-provider relationship and perceived coercion with service contact evaluation.

RESULTS

Consumer-provider relationship was negatively associated with perceived coercion (effect size=.08). Perceived coercion was negatively associated with service contact evaluation (effect size=.34). Perceived coercion was positively associated with time in the program (effect size=.17) and negatively associated with length of the service contact (effect size=.14). Effect sizes ranging from .08 to .34 are typically considered small to medium.

CONCLUSIONS

Findings demonstrate that for consumers, a positive response to service contacts indicated that they did not feel coerced. With consumers whose connection to services is tenuous, an immediate positive response to service contacts may be vital to maintain engagement. Research is needed to identify supportive case manager strategies that facilitate relationship building.

RAS function and protein kinase cascades

This paper reviews recent progress in understanding the function of RAS in three systems: the budding yeast (Saccharomyces cerevisiae), the fission yeast (Schizosaccharomyces pombe) and Xenopus laevis oocytes. One of the functions of RAS in S. cerevisiae is the stimulation of adenylate cyclase. This leads to the activation of the cAMP-dependent protein kinases--a function that has probably not been conserved in evolution. The immediate function of RAS in S. pombe is not known, but it may lead to the activation of a protein kinase cascade. This cascade has likely been conserved in evolution and linkage between it and RAS can be demonstrated in cell-free extracts from Xenopus oocytes. The Xenopus cell-free system provides a means to test specific hypotheses about RAS function and to isolate targets of RAS.

Severe botulism after focal injection of botulinum toxin

We report a 34-year-old woman who developed clinical botulism after the cosmetic use of an unapproved botulinum toxin type A. Electrophysiologic findings demonstrated complete denervation with complete electrical silence. She had a lengthy recovery but was able to ambulate by discharge.

Identification of potential CSF biomarkers in ALS

BACKGROUND

The clinical diagnosis of ALS is based entirely on clinical features. Identification of biomarkers for ALS would be important for diagnosis and might also provide clues to pathogenesis.

OBJECTIVE

To determine if there is a specific protein profile in the CSF that distinguishes patients with ALS from those with purely motor peripheral neuropathy (PN) and healthy control subjects.

METHODS

CSF obtained from patients with ALS, disease controls (patients with other neurologic disorders), and normal controls were analyzed using the surface-enhanced laser desorption/ionization time-of-flight mass spectrometry proteomics technique. Biomarker sensitivity and specificity was calculated with receiver operating characteristic curve methodology. ALS biomarkers were purified and sequence identified by mass spectrometry-directed peptide sequencing.

RESULTS

In initial proteomic discovery studies, three protein species (4.8-, 6.7-, and 13.4-kDa) that were significantly lower in concentration in the CSF from patients with ALS (n = 36) than in normal controls (n = 21) were identified. A combination of three protein species (the "three-protein" model) correctly identified patients with ALS with 95% accuracy, 91% sensitivity, and 97% specificity from the controls. Independent validation studies using separate cohorts of ALS (n = 13), healthy control (n = 25), and PN (n = 7) subjects confirmed the ability of the three CSF protein species to separate patients with ALS from other diseases. Protein sequence analysis identified the 13.4-kDa protein species as cystatin C and the 4.8-kDa protein species as a peptic fragment of the neurosecretory protein VGF.

CONCLUSION

Additional application of a "three-protein" biomarker model to current diagnostic criteria may provide an objective biomarker pattern to help identify patients with ALS.

Long-term risk for depressive symptoms after a medical diagnosis

BACKGROUND

This study examines the risk of development of significant depressive symptoms after a new diagnosis of cancer, diabetes, hypertension, heart disease, arthritis, chronic lung disease, or stroke.

METHODS

The study used 5 biennial waves (1992-2000) of the Health and Retirement Study to follow a sample of 8387 adults (aged 51 to 61 years and without significant depressive symptoms in 1992) from 1994 to 2000. Time-dependent Cox regression models estimated adjusted hazard ratios (HRs) for an episode of significant depressive symptoms after a new diagnosis for each of the 7 medical conditions.

RESULTS

Within 2 years of initial diagnosis, subjects with cancer had the highest hazard of depressive symptoms (HR, 3.55; 95% confidence interval [CI], 2.79-4.52), followed by subjects with chronic lung disease (HR, 2.21; 95% CI, 1.64-2.79) and heart disease (HR, 1.45; 95% CI, 1.09-1.93). The hazard for depressive symptoms for most of these diseases decreased over time; however, subjects with heart disease continued to have a higher risk for depressive symptoms even 2 to 4 years and 4 to 8 years after diagnosis, and a significantly higher hazard for depressive symptoms developed for persons with arthritis 2 to 4 years after diagnosis (HR, 1.46; 95% CI, 1.11-1.92).

CONCLUSION

The findings identify several high-risk patient groups who might benefit from depression screening and monitoring to improve health outcomes in this vulnerable population facing new medical illnesses.

Rapid Cyanide Detection Using the Cyantesmo® Kit

BACKGROUND

Sources of cyanide exposure are many, including combustion of plastic and vinyl, such as in a house fire, laboratory or industrial exposures including exposure in the electroplating industry both of printed circuit boards and in jewelry work. Rapid and definitive diagnosis of cyanide poisoning is unavailable in the emergency department setting. It is desirable to make a definitive diagnosis in order to prevent potential complications of empiric treatment of presumptive cyanide poisoning from the cyanide antidote kit currently approved by the US Food and Drug Administration (FDA). We investigated a technique to detect cyanide currently utilized by water treatment facilities to determine if it can be applied to rapidly detect concentrations of cyanide in the clinically important range.

METHODS

Varying standardized dilutions of KCN ranging from 0.25 microg/mL to 30 microg/mL were acidified with a drop of sulphuric acid in a closed system under a ventilation hood. Cyantesmo test strips were placed into the test tubes above the fluid level where liberated HCN gas interacted with the test strip to effect a color change. Color changes were compared to negative controls and to each other.

RESULTS

The test strips demonstrated an incrementally increasing deep blue color change over a progressively longer portion of the test strip in less than 5 minutes for each concentration of KCN including 1, 3, 10, and 30 microg/mL. The concentrations of 0.25, 0.5, and 0.75 required more than 2 hours to begin demonstration of any color change.

CONCLUSION

The Cyantesmo test strips accurately and rapidly detected, in a semi-quantifiable manner, concentrations of CN greater than 1 microg/mL contained in each test sample. Future work to validate this test in blood and in clinical specimens is planned.
