A network analysis of Hurricane Maria-related traumatic stress and substance use among Puerto Rican youth

Youth exposed to natural disasters are at risk of developing trauma-related symptoms as well as engaging in substance use. Although previous research has established associations between disaster-related stressors and substance use in youth, less has focused on how symptoms of posttraumatic stress disorder (PTSD) may underpin this association. The current study used network analysis to identify specific PTSD symptoms associated with substance use following a natural disaster. Participants were 91,732 youths (Grades 3-12) from across Puerto Rico who completed a needs assessment 5-9 months after Hurricane Maria made landfall in September 2017. We examined associations between PTSD symptoms and substance use, identified clusters of symptoms and bridges between them, and explored age- and binary gender-related differences in associations between specific PTSD symptoms and substance use. Analyses identified two symptom communities: (a) arousal and reactivity, negative alterations in cognition and mood, and substance use, and (b) avoidance and intrusion. Broader findings suggested that substance use was most strongly associated with PTSD-related irritability and angry outbursts among youths. Surrounding nodes explained only 4.1% of the variance in substance use, but this was higher among youths who reported not having a supportive adult, R2 = 8.5; friend, R2 = 7.9; or teacher/counselor, R2 = 7.7, in their life. The bridge symptoms of sleep disruption and physiological reactivity were identified as potentially critical intervention targets for disrupting PTSD symptom networks after a natural disaster. Implications for triaged mental health care following natural disasters and directions for future research are discussed.

Evidence-Based Assessment of Substance Use Disorder

The current review describes updated information on the evidence-based assessment of substance use disorder. We offer an overview of the state of the science for substance-related assessment targets, instruments (screening, diagnosis, outcome and treatment monitoring, and psychosocial functioning and wellbeing) and processes (relational and technical) as well as recommendations for each of these three components. We encourage assessors to reflect on their own biases, beliefs, and values, including how those relate to people that use substances, and to view the individual as a whole person. It is important to consider a person's profile of symptoms and functioning inclusive of strengths, comorbidities, and social and cultural determinants. Collaborating with the patient to select the assessment target that best fits their goals and integration of assessment information in a holistic manner is critical. We conclude by providing recommendations for assessment targets, instruments, and processes as well as recommendations for comprehensive substance use disorder assessment, and describe future directions for research.

Intervention and Implementation Characteristics to Enhance Father Engagement: A Systematic Review of Parenting Interventions

In recent years, the prevalence rates of children's mental health disorders have increased with current estimates identifying that as many as 15-20% of children meet criteria for a mental health disorder. Unfortunately, the same robust parenting interventions which have long targeted some of the most common and the most treatable child concerns (e.g., externalizing, disruptive behavior, and aggression) have also shown consistently low rates of father engagement. This persistent issue of engagement comes in the wake of an increasingly large body of literature which highlights the unique positive contributions fathers make to children and families when they are engaged in parenting interventions. As the role fathers play in families shifts to become more inclusive of childcare responsibilities and less narrowly defined by financial contributions, it becomes increasingly important to understand how best to engage fathers in interventions that aim to enhance parenting efficacy and family outcomes such as coparenting. The current review examined intervention (e.g., format and setting) and implementation characteristics (e.g., training and agency-level changes) associated with father engagement. Particular attention is paid to studies which described father-specific engagement strategies (e.g., inviting fathers directly, father-only groups, and adapting intervention to incorporate father preferences). A total of 26 articles met inclusion criteria after screening and full-text review. Results indicate that father engagement (i.e., initiating treatment) remains low with 58% of studies either not reporting father engagement or having engagement rates below 50%. More than two-thirds of studies did not include specific father engagement strategies. Those that did focused on changes to treatment format (e.g., including recreational activities), physical treatment setting (e.g., in-home and school), and reducing the number of sessions required for father participation as the most common father-specific engagement strategies. Some studies reported efforts to target racially and ethnically diverse fathers, but review results indicated most participants identified as Non-Hispanic White. Interventions were largely standard behavioral parent training programs (e.g., PCIT and PMT) with few exceptions (e.g., COACHES and cultural adaptations), and very few agencies or programs are systematically making adjustments (e.g., extended clinic hours and changes to treatment format) to engage fathers. Recommendations for future directions of research are discussed including the impact of differential motivation on initial father engagement in treatment, the importance of continuing to support diverse groups of fathers, and the potential for telehealth to address barriers to father engagement.

Culturally Responsive Telepsychology & mHealth Interventions for Racial-Ethnic Minoritized Youth: Research Gaps and Future Directions

Telepsychology and mHealth (TPmH) services for youth and their families have become increasingly prevalent in recent years. However, significant limitations in theory, research, and policy introduce questions about the effectiveness of such interventions, particularly for racial-ethnic minoritized youth and their families, who already contend with inequities in mental health treatment access and outcomes. Although TPmH have the potential to reduce barriers to mental health services in ways that may benefit racial-ethnic minoritized youth and their families, the mental health field must first grapple with limitations in culturally responsive TPmH work to avoid perpetuating existing mental health inequities. As such, this article begins by briefly reviewing extant literature on (1) TPmH for youth, (2) culturally adapted or culturally responsive evidence-based interventions for racial-ethnic minoritized youth and families, and (3) the intersection of TPmH and culturally responsive interventions. Informed by the gaps identified by this review, we provide recommendations for future directions in culturally responsive TPmH for racial-ethnic minoritized youth and families. These recommendations have been organized into four overarching categories: (1) conceptual and theoretical recommendations, (2) research priorities, (3) practice and policy recommendations, and (4) engagement and access recommendations. These recommendations offer novel ideas for researchers, clinicians, funding agencies, policy-makers, and other key stakeholders and are intended to facilitate equity in TPmH for racial-ethnic minoritized youth and their families.

Lay Health Workers Engaging Latino Fathers: A qualitative study

Behavioral Parent Training programs (BPTs) are evidence-based interventions that have been shown to be effective when implemented in various contexts and with different racial/ethnic minority families. Despite evidence showing their effectiveness within the Latinx community, disparities in access to BPTs still persist. In addition, fathers continue to show low rates of attendance and engagement despite evidence suggesting positive outcomes for the youth and family when fathers are involved in BPT treatment. Lay health workers (LHWs), community members without specialized metal health training that often live in the communities they serve, have been identified as engagement specialists that are uniquely positioned to reduce racial/ethnic disparities in access to services. The current study utilized a qualitative approach to examine this workforce's perspectives on engaging Latino fathers in parenting services in children's mental health. Qualitative themes revealed that LHWs have generally positive attitudes towards engaging Latino fathers in parenting interventions (i.e., benefits to parent-child relationship) despite experiencing barriers to engagement (e.g., culturally defined gender roles, fathers being less likely to ask for help). Themes also elucidate various engagement strategies that LHWs use to engage fathers in treatment (e.g., adapting treatment setting). Considerations for future LHW trainings and workforce development are discussed with a focus on how to incorporate cultural values in the use of father-engagement strategies.

Association between ethnicity and hypertension in Northern Colombia in 2015

Background

Studies in the United States have shown a genetic predisposition to hypertension in individuals of African descent. However, studies on the associations between ethnic groups and hypertension in Latin America are lacking and the limited results have been inconsistent. The objective of this study is to determine whether Afro-Colombian ethnicity increases the risk of hypertension.

Methods

This study is a secondary data analysis of a cross sectional study from five provinces in Northern Colombia. Randomly selected individuals (N = 2613; age-range 18–74 years) enrolled in a health care insurance company underwent physical examinations and completed questionnaires regarding ethnicity, lifestyle, and other risk factors. Hypertension in these patients was determined. Unadjusted and adjusted logistic regression analysis were calculated to determine the association between ethnicity and hypertension.

Results

No association between Afro-Colombian ethnicity and hypertension was found (odds ratio [OR], 0.85; 95% confidence interval [CI], 0.66–1.09). As expected, people with a body mass index (BMI) of 30 or higher were at a greater risk of having hypertension (OR, 3.12; 95% CI, 2.35–4.16) compared with those with a normal BMI.

Conclusions

Findings from this study suggest no independent association between Afro-Colombian ethnicity and hypertension. Further research should focus on genotyping or socioeconomic factors such as income level.

Combating the Conspiracy of Silence: Clinician Recommendations for Talking About Racism-Related Events With Youth of Color

Graphic videos of race-based violence, including police brutality toward Black people and anti-Asian hate crimes, have exploded over the past year. While documentation of these horrific acts has brought visibility to the pervasiveness of racial discrimination, it has also resulted in youth of color being exposed to racial stressors more than ever before across numerous social media and news platforms.^1-3 Beyond the significant race-related stress already experienced by youth in school contexts,⁴ this increased exposure to racism via media is concerning, as both direct and vicarious exposure to racial discrimination can compromise psychological well-being of youth and cause trauma-like symptoms, such as intrusive thoughts, vigilance, and depression.^3,5.

"Todo Se Hace de Corazón:" An Examination of Role and Identity Among Latina Promotoras de Salud

Promotoras de salud are community health workers that mostly help the underserved members of Latinx communities. They seek to reduce health disparities through community engagement and work that is voluntary or mostly unpaid. While there is evidence that promotoras aid in prevention, follow-up care, and treatment adherence, little is known about promotoras themselves, specifically, the impact that fulfilling their roles has on their views of themselves and their service identities. Fourteen Spanish-speaking, Latina promotoras were interviewed individually about their experiences and their motivation for the role. Four themes emerged from the content analysis of the participant responses: "Uno Nace Siendo Promotora:" One is Born Being a Promotora, "Poner Esa Semillita:" To Plant a Seed by Sharing Knowledge, "Es un Regalo Ser Promotora:" It is a Gift to be a Promotora, and "Se Hace por Amor pero también Hay Necesidad:" A Labor of Love but there are Needs too. The findings show that assuming and enacting the promotora role had positive benefits, both personal and professional, despite the often-limited recognition they received. The findings have multiple implications for the development of health and prevention programs, particularly for those that involve promotoras de salud.

How do Lay Health Worker Engage Caregivers? A Qualitative Study to Enhance Equity in Evidence-Based Parenting Programs

Engaging caregivers in their children's mental health treatment is critical for delivering high quality, evidence-based care, particularly for young children with externalizing behaviors. Lay health workers (LHWs), including peer providers and promotoras de salud, have been identified as important workforces in addressing structural and stigma-related barriers to engagement in mental health services. Importantly, research has suggested that LHWs may be integral in efforts to address engagement disparities in evidence-based behavioral parent training programs (BPTs) for Latinx caregivers. The purpose of the study was to understand how different LHW workforces engage caregivers within their usual services, in order to inform strategies that improve access to and engagement in BPTs. Qualitative interviews were conducted with two different LHW workforces: volunteer LHWs (i.e., promotoras de salud) (n = 14), who were part of a community-embedded network, and paid LHWs (i.e., parent support partners, home visitors) (n = 9) embedded within children's mental health agencies. Participants were predominately Latinx (79%) and female (96%). Qualitative analyses revealed three primary themes related to engagement strategies used by LHWs to address barriers to care: 1.) Building Trust, 2.) Empowerment, 3.) Increasing Access. Although the majority of themes and sub-themes were consistent across the two LHW workforces, agency-embedded LHWs often discussed having the means to provide resources through their organizations, whereas community-embedded LHWs discussed acting as a bridge to services by providing information and conducting outreach. Findings have implications for partnering with different workforces of LHWs to increase equity in access to BPTs.

Universal Teacher-Child Interaction Training in Early Special Education: A Pilot Cluster-Randomized Control Trial

Using a pilot matched-pairs cluster-randomized control trial, we evaluated the acceptability and preliminary outcomes of universal Teacher-Child Interaction Training (TCIT-U) with students with disabilities in early special education programs. Twelve classrooms (clusters) were paired by age and type and then randomly assigned within pairs to either TCIT-U (81 students, 20 teachers) or wait-list control (63 students, 16 teachers) with services as usual. We analyzed the effects of TCIT-U on (a) teachers' skills acquisition via masked observational coding and (b) students' behavior and developmental functioning via teacher questionnaires. For child-directed interaction skills, teachers receiving TCIT-U exhibited significantly greater increases in behavior descriptions and labeled praise than teachers who did not receive TCIT-U at posttreatment and follow-up. No significant group differences were observed in use of teacher-directed interaction skills. Qualitative data from teachers expanded on these findings, suggesting that teachers found child-directed interaction skills more acceptable than teacher-directed interaction skills. Teachers receiving TCIT-U reported small but significant improvements in student behavior problems and socioemotional functioning at posttreatment and follow-up, as compared to wait-list students. We discuss considerations for future implementation and tailoring of TCIT for young students with disabilities, which may have positive impacts on future cohorts of students beyond teachers' initial training.

Osborne-Cotterill Lesion a Forgotten Injury: Review Article and Case Report

Osborne-Cotterill lesion is an osteochondral fracture located in the posterolateral margin of the humeral capitellum, which may be associated with a defect of the radial head after an elbow dislocation. This lesion causes instability by affecting the lateral ulnar collateral ligament over its capitellar insertion, which is associated with a residual capsular laxity, thereby leading to poor coverage of the radial head, and hence resulting in frequent dislocations. We present a 54-year-old patient, a physician who underwent trauma of the left elbow after falling from a bike and suffered a posterior dislocation fracture of the elbow. The patient subsequently presented episodes of instability, and additional work-up studies diagnosed the occurrence of Osborne-Cotterill lesion. An open reduction and internal fixation of the bony lesion was performed, with reinsertion of the lateral ligamentous complex. Three months after surgery, the patient was asymptomatic, having a flexion of 130º and extension of 0º, and resumed his daily activities without any limitation. Currently, the patient remains asymptomatic 2 years after the procedure. Elbow instability includes a large spectrum of pathological conditions that affect the biomechanics of the joint. The Osborne-Cotterill lesion is one among these conditions. It is a pathology that is often forgotten and easily overlooked. Undoubtedly, this lesion requires surgical intervention.

Unilateral Open-lip Schizencephaly with Tonsillar Herniation in a Preterm Infant

Schizencephaly is a rare type of neuronal migration disorder characterized by the presence of a cerebral hemispheric cleft that extends from lateral ventricles to the cortical surface of the brain. We report a rare case of prenatally diagnosed unilateral schizencephaly in a late preterm infant who manifested with rapidly progressive hydrocephalus with massive enlargement of posterior cerebrospinal fluid spaces with tonsillar herniation that was successfully treated with placement of a ventriculoperitoneal shunt.

Ethnic minority community therapists' acculturation and reported adaptations to children's evidence-based practices

OBJECTIVE

This study examined associations between ethnic minority therapists' reports of acculturation and adaptations made to multiple evidence-based practices (EBPs) in children's community mental health services. Multilevel modeling was used to analyze therapist- and practice-level predictors of Augmenting and Reducing/Reordering adaptations, the two subscales of the Adaptations to Evidence-Based Practices Scale (AES; Lau et al., 2017).

METHOD

An online survey was completed by 235 therapists (86% women, M_age = 34.82 years, 68.1% Hispanic/Latino) as part of a larger study examining EBP sustainment in Los Angeles County, California. Acculturation was measured through therapist reports of cultural identity and language use using the Abbreviated Multidimensional Acculturation Scale (Zea, Asner-Self, Birman, & Buki, 2003).

RESULTS

Analyses showed that the effect of Heritage Cultural Identity on Augmenting adaptations was moderated by Heritage Language Use. There was a significant interaction between Heritage and United States Cultural Identity dimensions in predicting Reducing/Reordering adaptations. Therapists who reported higher levels of Heritage Cultural Identity and lower levels of United States Cultural Identity reported the fewest Reducing/Reordering adaptations, whereas therapists who reported higher levels of affiliation with both their Heritage Culture and United States Culture reported making the most Reducing/Reordering adaptations. Language acculturation and other cultural factors such as Ethnicity and Generational Status did not predict either adaptation type. Therapists who reported more favorable perceptions of the EBP reported making fewer Reducing/Reordering adaptations.

CONCLUSION

Findings suggest that cultural identity is linked to the likelihood that ethnic minority therapists may adapt EBPs. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Qualitative Reports of How and When Therapists Adapt Children's Evidence-Based Practices during Community Implementation

This study analyzed qualitative therapist reports of adaptations to the delivery of multiple evidence-based practices (EBPs) within the context of a system-driven reform of children's community mental health services to understand how therapists adapt EBPs as well as contexts of these adaptations to identify when these adaptations are made. The study sought to complement and expand upon previous quantitative survey findings of two categories of Augmenting and Reducing/Reordering adaptations to EBPs. Data included interviews from 60 therapists (88.3% female, 61.7% Latina/o, 80.0% unlicensed) across 20 program sites in 11 mental health agencies that served racial/ethnically diverse children. Interviews were coded to identify themes surrounding the types of adaptations made and the contexts for these adaptations. The majority of therapists' qualitative descriptions of adaptations converged with the 2 broad categories in the Augmenting and Reducing/Reordering Framework, with therapists describing augmenting (e.g., modifying presentation, lengthening or extending pacing) most often, and reducing/reordering adaptations were discussed less frequently. Child and family characteristics were most frequently cited as indications prompting adaptations; however, the specific characteristics motivating adaptations differed by type. Therapists reporting using augmenting adaptations in the context of a wide range of client characteristics, whereas reducing/reordering adaptations occurred more specifically as a function of clinical presentation, family and caregiver functioning, and emergent life events. Therapists described making adaptations to improve the fit of multiple EBPs for the clients they served. Findings could have implications for implementation efforts with diverse clients served in community settings.

Community Therapist Reports of Client Engagement Challenges During the Implementation of Multiple EBPs in Children's Mental Health

This study investigated therapist reports of client engagement challenges in delivering evidence-based practices (EBPs), within the context of a large-scale implementation of multiple practices in children's mental health services. Data were drawn from an online survey of 668 therapists (88% female, 35.0% Non-Hispanic White). The majority of therapists (75.4%) endorsed at least one client engagement challenge during their implementation of an EBP with an identified client over the previous two months. Two types of EBP client engagement challenges with distinct correlates but similar overall frequencies could be readily differentiated - Expressed Client Concerns and Limited Client Engagement in therapy activities. Limited Client Engagement were more commonly reported for clients with externalizing problems and by therapists with higher emotional exhaustion and negative perceptions of the specific EBP being delivered, whereas Hispanic/Latino therapists were less likely to report Limited Client Engagement. In contrast, Expressed Client Concerns were more commonly reported by therapists with positive general attitudes towards EBPs, and among therapists delivering a parent training EBP. Limited Client Engagement but not Expressed Concerns were linked with therapists' self-reported ability to carry out the EBP with the target client. Findings suggest that client engagement challenges are frequent during the delivery of EBPs, but may impact implementation differently based on whether they relate to challenges in engaging clients in therapy activities versus addressing concerns raised by clients.

Un caso de desorden del desarrollo sexual en un canino mestizo

The disorders of sex development can occur in different domestic animals, but they are not very common. They are classified as sex chromosomic disorders, gonadal sex development disorders andphenotypic sex disorders and have different subcategories. The aim of this study was to describe the phenotypic, chromosomal and anatomical traits of the reproductive organs of a canine patient 3-year-old, apparently female with disorder of sexual development, which presented a protuberance into the vagina with bleeding andpus, which anamnesis male behavior report. A general examination was performed by systems, ventral abdominal ultrasound,latero-lateral radiography, blood count and karyotype whit R-replicative bands. After the evaluation found an enlarged clitoris (pseudopene) with urethral opening that showed resistance to placing a catheter. Radiography showed a structure similar to penis bone and the ultrasonography a structure consistent with the cervix in a female and a structure similar to gonadal tissue in the side. The karyotype was typical of a male, compatible with a male pseudo-hermaphrodite, which classifies the individual as XY with a phenotypic disorder of sex development (78, XY) according to the new classification. With the diagnostic tools found in Colombia is possible to make an appropriate differential diagnosis. But nevertheless, lack of availability of specific diagnostic tests such as FISH and serological measurements.

Nanowires and nanoribbons formed by methylphosphonic acid

The production and physical properties of nanowires and nanoribbons formed by methylphosphonic acid (MPA)--CH3PO(OH)2--were investigated. These structures are formed on an aluminum coated substrate when immersed in an ethanolic solution of MPA for several days. A careful investigation of the growth conditions resulted in a narrow window of solution concentrations and temperatures for the successful development of nanowires and nanoribbons. Several different techniques were employed to characterize these nanostructures: (1) Photoluminescence experiments showed a strong emission at 2.3 eV (green), which is visible to the naked eye; (2) X-ray diffraction experiments indicated a significant cristalinity, in agreement with atomic force microscopy (AFM) and transmission electron microscopy (TEM) morphology images, which show organized nano-scale wires and ribbons, (furthermore, AFM-Phase and TEM images also suggest that nanoribbons are formed by well-aligned nanowires); (3) Conductive-AFM experiments revealed an intermediary conductivity for these structures (10(-1)/Ohm x m), which is similar to some intrinsic semiconductors and; (4) finally, Infrared, Raman, and X-Ray Photoelectron Spectroscopies produced information about the contents, structure, and composition of both wires and ribbons.

Pleasurable auditory hallucinations

OBJECTIVE

The focus in auditory hallucination (AH) research is usually on the negative impact of the experience itself. There are practically no studies on whether voices can be perceived as pleasurable. The aim of the present study was to assess the frequency of voices as a pleasurable experience in a psychotic patient population.

METHOD

A total of 160 patients with AHs (89 schizophrenia and 17 other psychoses) were assessed with the psychotic symptom rating scale (PSYRATS) for AHs, including an added item on whether the experience was pleasurable.

RESULTS

Twenty-eight patients (26%) reported the voices as a pleasurable experience and 10 of them did so frequently. Pleasurable hallucinations showed negative associations with amount and intensity of distress, degree of negative content and loudness. Positive associations were apparent with chronicity and perceived control over the voices.

CONCLUSION

Pleasurable hallucinations can be detected in a substantial proportion of patients, and cross validated with existing instruments.

[Evaluation of auditory hallucinations: the PSYRATS scale]

INTRODUCTION

Translate and adapt the PSYRATS scale for evaluation of auditory hallucinations to Spanish and study the psychometric behavior.

METHOD

After being translated into Spanish, the scale was applied to a sample of 80 patients. All had a history of auditory hallucinations, 71 with Schizophrenia and 9 with schizoaffective disorder according to DSM-IV diagnostic criteria. Demographic and clinical data were collected by a semi-structured interview, tape recording the sessions for every patient. For the reliability study, 27 patients of the sample were evaluated independently by the first four auhors of this paper. For the study of concurrent validity the results of this scale were compared with those of the Krawiecka scale in 60 patients of the sample.

RESULTS

In the Spanish version, the 11 items were conserved with slight modifications in two of them. The scale showed high reliability with coefficients in the 11 items higher than 0.85. The concurrent validity showed high association between the hallucination item of the Krawiecka scale and the PSYRATS. In the factorial analysis four factors that explained 62% of the variance were obtained.

CONCLUSIONS

The Spanish version of the PSYRATS (for hallucinations) is, to our knowledge, the first scale adapted to Spanish for the study of auditory hallucinations, showing excellent psychometric properties.

The role of discriminant analysis in the refinement of customer satisfaction assessment

OBJECTIVE

To test discriminant analysis as a method of turning the information of a routine customer satisfaction survey (CSS) into a more accurate decision-making tool.

METHODS

A 7-question, 10-multiple choice, self-applied questionnaire was used to study a sample of patients seen in two outpatient care units in Valparaíso, Chile, one of primary care (n=100) and the other of secondary care (n=249). Two cutting points were considered in the dependent variable (final satisfaction score): satisfied versus unsatisfied, and very satisfied versus all others. Results were compared with empirical measures (proportion of satisfied individuals, proportion of unsatisfied individuals and size of the median).

RESULTS

The response rate was very high, over 97.0% in both units. A new variable, medical attention, was revealed, as explaining satisfaction at the primary care unit. The proportion of the total variability explained by the model was very high (over 99.4%) in both units, when comparing satisfied with unsatisfied customers. In the analysis of very satisfied versus all other customers, significant relationship was identified only in the case of the primary care unit, which explained a small proportion of the variability (41.9%).

CONCLUSIONS

Discriminant analysis identified relationships not revealed by the previous analysis. It provided information about the proportion of the variability explained by the model. It identified non-significant relationships suggested by empirical analysis (e.g. the case of the relation very satisfied versus others in the secondary care unit). It measured the contribution of each independent variable to the explanation of the variation of the dependent one.

Healthcare security on the front line against domestic violence and stalking affecting the workplace

Domestic violence and stalking affect the health and safety of employees in the workplace. Security and EAP staff, says the author, can give healthcare facilities the edge in front-line deterrence. The article discusses definitions, key factors to consider, and how to go about dealing with these problems.

Hospitals present a complex security challenge

Healthcare violence is increasing while funding is shrinking. The author discusses the various security issues involved, the concept of funneling, and the role security directors should play in this environment.

Security and human resource professionals fight violence in the workplace

The author focuses on how security and human resources must work together to fight violence. He provides specific actions they can take to protect employees from violent people and violent actions. With the help of training, security technology, and prevention awareness, all employees can become active participants in the reduction of violence.

Plasma renin activity in chagasic patients with and without congestive heart failure

Chagasic patients with advanced heart disease have fluid retention-dependent symptoms. Since fluid retention is mostly dependent on the renin-angiotensin-aldosterone system, chagasic patients with congestion related symptoms should have activation of the renin-angiotensin-aldosterone system. The purpose of this investigation was to determine the plasma renin activity baseline values of chagasic patients with and without congestive heart failure. Twenty-eight patients with positive serology for Chagas' disease were studied. Nineteen patients were asymptomatic (functional class I New York Heart Association) and nine were symptomatic (functional classes II-IV). Cardiac catheterization and ventricular cineangiography were performed on 20 patients. The symptomatic patients had significantly higher plasma renin activity levels (4.11 +/- 1.03 ng/ml/h) than the asymptomatic patients (1.08 +/- 0.11 ng/ml/h, P < 0.001) and the normal sedentary controls (1.65 +/- 0.22 ng/ml/h, P < 0.05, mean +/- S.E.). The plasma renin activity baseline values of the asymptomatic and symptomatic patients correlated directly with the baseline heart rate (r = 0.77, P < 0.0001). The symptomatic patients had larger ventricular volumes, moderately depressed ejection fractions and increased left ventricular end-diastolic pressures. The plasma renin activity baseline values also correlated directly with the left ventricular diastolic pressures (r = 0.70, P < 0.0006) and with the left ventricular diastolic (r = 0.66, P < 0.001) and systolic volumes (r = 0.67, P < 0.001). These results indicate that chagasic patients with fluid retention-dependent symptoms and hemodynamic evidence of left ventricular systolic dysfunction have activation of the renin-angiotensin-aldosterone system.

Contribution of tumor necrosis factor-alpha and glucocorticoid in hydrazine sulfate-mediated protection against endotoxin lethality

Hydrazine sulfate pretreatment has previously been shown in our laboratory to protect normal mice against endotoxin and D-galactosamine-sensitized mice against both exogenous tumor necrosis factor (TNF) and endotoxin. An intact pituitary is required for manifestation of the protective effects. Further, we have demonstrated that hydrazine sulfate pretreatment specifically modulates the TNF response to lipopolysaccharide (LPS) in mouse macrophages in vitro. This in vivo study was performed to test whether a reduced TNF response and/or increased glucocorticoid response may contribute to hydrazine sulfate protection against LPS-induced lethality in vivo. The results presented here establish that hydrazine sulfate pretreatment selectively attenuates circulating TNF levels following LPS challenge. Moreover, adrenalectomy abrogates hydrazine sulfate protection but does not prevent hydrazine sulfate attenuation of circulating TNF levels in response to LPS. Hydrazine sulfate-mediated protection is, however, restored permissively by corticosterone. Thus, the mechanism by which hydrazine sulfate protects against LPS lethality in adrenalectomized mice includes TNF modulation in response to endotoxin, as well as a pivotal requirement for glucocorticoid.

Differential medication of child versus adult postoperative patients: the effect of nurses' assumptions

We examined nurses' assumptions concerning children and analgesia that have been hypothesized to explain the differential medication of postoperative child and adult patients. One hundred fourteen nurses from various pediatric and adult inpatient units of a large, urban teaching hospital were included in the study. A questionnaire consisting of four vignettes describing two hypothetical postoperative situations involving a child and adult patient, questions concerning choice of analgesic and assessment of pain for the hypothetical patients, and questions concerning the nurses' assumptions about children and analgesia was distributed to each nurse. The findings illustrate a pattern of differential medication of hypothetical child relative to hypothetical adult postoperative patients. The belief that children feel less pain than adults and concern about respiratory depression were associated with nurses' analgesia decisions.

Effects of maternal distraction versus reassurance on children's reactions to injections

Manipulated experimentally mothers' verbal behavior during a routine intramuscular injection in order to help clarify the role of nonprocedural talk (distraction) and parental reassurance on children's reaction to the injection. 42 child-mother dyads were recruited from a general pediatric primary care clinic and were randomly assigned to a parental reassurance, parental nonprocedural talk (distraction) or minimal-treatment control group. Children in the maternal distraction condition exhibited significantly less distress during the immunization injection than those in the reassurance and control conditions. Specifically, children in the maternal distraction group exhibited less crying than children in the other two groups. Children in the reassurance and control groups did not differ from each other in terms of behavioral distress. The present findings serve further to bolster the evidence for the efficacy of maternal distraction as a way to ameliorate child distress during invasive medical procedures.

Endogenous and exogenous glucocorticoids have different roles in modulating endotoxin lethality in D-galactosamine-sensitized mice

Endotoxin sensitivity and dexamethasone protection have been assessed in mice that were adrenalectomized and also treated with D-galactosamine at the time of endotoxin challenge. Our data establish that adrenalectomy did not detectably alter the magnitude of the increased sensitivity induced by D-galactosamine alone. Furthermore, protection provided by acute exogenous glucocorticoid treatment was still demonstrable in these mice and was not influenced by chronic experimentally induced glucocorticoid deficiency. Our data confirm that the adrenalectomized mouse model of endotoxin lethality is characterized by increased sensitivity to endotoxin and establish that the magnitude of this sensitizing effect is more than 100-fold. We also show for the first time that adrenalectomy causes an appreciable kinetic shift in the endotoxic crisis and that dexamethasone, given at the time of endotoxin challenge, will significantly reverse the increased sensitivity to lethality. Our results indicate that the protective effects of corticosteroids may involve important chronic as well as acute responses. In particular, we conclude that endogenous glucocorticoid need not always increase host resistance to endotoxin, nor does such a circumstance eliminate the possibility for exogenous glucocorticoid-mediated protective effects.

Impact of Children's Sickle Cell History on Nurse and Physician Ratings of Pain and Medication Decisions

The process of assessing and treating recurrent and unpredictable pain in children with sickle cell disease (SCD) is complex. A conceptual model is presented to aid in understanding the influence of mediating factors such as professional knowledge, attitudes and beliefs about pain, and learning history on the interpretation of objective data and resulting treatment decision. One aspect of this model, the effect of disease history on pain assessment and treatment decisions, is tested in an experimental study of SCD pain in children. Results suggest that nurses, but not pediatric residents, provide lower doses of narcotic analgesics to children with histories of frequent, as opposed to occasional, hospitalization for pain, although they do not differ in their ratings of the pain of children with these histories. Neither professional experience and training nor reported attitudes and beliefs about pain in children are related to this pattern of decision making. Results are discussed in terms of the aversive impact of repeated exposure to a noxious stimulus (pain behaviors) on caregiver interpretation of pain cues.

Effects of parent presence on children's reactions to injections: behavioral, physiological, and subjective aspects

Observed 47 children ranging in age from 13 months to 7 years 9 months receiving injections as part of a regular visit to a pediatric clinic. Twenty-three children were randomly assigned to a condition with parent (mainly mothers) present and 24 to a condition with parent absent. During the medical procedure, the child's reactions were observed via videotape (for later behavioral coding) and physiological recording (to measure heart rates). Following the injection, data were collected on the child's preference of condition (either parent present or parent absent) for future injections. Older children (but not younger ones) showed significantly more behavioral distress when the parent was present. However, the oldest children's preference of condition for future injections was overwhelmingly that of parent present (86%).

Metacyclic neutralizing effect of monoclonal antibody 10D8 directed to the 35- and 50-kilodalton surface glycoconjugates of Trypanosoma cruzi

It was shown in this work that the infectivity of metacyclic forms of Trypanosoma cruzi was affected upon interaction with the monoclonal antibody (10D8), which reacts with a carbohydrate epitope of the 35- and 50-kilodalton (kDa) surface glycoconjugates. The invasion of Vero cells by metacyclic forms of strains Tulahuen and G was inhibited 50 to 67% in the presence of 10D8 (10 micrograms/ml), whereas a nonrelated monoclonal antibody to Plasmodium berghei had no such effect. In mice that were inoculated with metacyclic forms preincubated with 10D8 or that had passively received 10D8 before challenge with metacyclic forms, a considerable decrease in the parasitemia levels was observed. The 35- and 50-kDa antigens were detectable by the galactose oxidase and sodium boro[3H]hydride procedure but not by surface iodination or metabolic labeling with [35S]methionine, suggesting that they may be of glycolipid nature. The finding that the 35- and 50-kDa antigens are major bands recognized by sera of mice immunized with killed metacyclic forms and protected against acute infection, in addition to the results with 10D8, indicate that these glycoconjugates may play an important role in the metacyclic form-host cell association that initiates T. cruzi infection.

[Bleeding esophageal varices: evaluation of medical and emergency surgical treatment]

The results of medical and emergency surgical treatment of 55 patients with bleeding esophageal varices were studied. Eighteen patients died (32.7%). Mortality relates to the severity of the liver disease and the number of blood transfusions required. There was a high incidence of recurrent hemorrhage. We recommend definitive porto-sistemic shunt after the bleeding episode has been controled.
