Polysubstance Use among Maryland High School Students: Variations across County-Level School Districts

BACKGROUND

Polysubstance use is a highly prevalent public health issue, particularly among adolescents, and decisions on prevention programming and policies are often made at the local level. While there is a growing literature examining patterns of polysubstance use among adolescents, little is known about differences in those patterns across geographic regions.

METHODS

Using a large, representative sample of high school students from the state of Maryland (n = 41,091) from the 2018 Maryland Youth Risk Behavior Survey, we conducted a latent class analysis (LCA) of adolescent substance use along nine binary indicators, including past 30-day combustible tobacco, e-cigarette, alcohol, and cannabis use, as well as lifetime use of prescription opioids, cocaine, heroin, methamphetamine, and injection drug use. Measurement invariance across counties was examined using the Multiple Indicators and Multiple Causes (MIMIC) procedure.

RESULTS

The results of the LCA show three classes of adolescent substance use for the total sample: (1) low substance use, (2) commonly used substances (i.e., e-cigarette, alcohol, and cannabis use), and (3) polysubstance use. The results from the MIMIC procedure demonstrated geographic differences in students' endorsement of specific indicators and their class membership.

CONCLUSIONS

These differences demonstrate the need for an examination of local trends in adolescent polysubstance use to inform multi-tiered prevention programming and policy.

Disparities in Medical School Clerkship Grades Associated with Sex, Race, and Ethnicity: A Person-Centered Approach

PURPOSE

To determine whether students' self-reported race/ethnicity and sex were associated with grades earned in 7 core clerkships. A person-centered approach was used to group students based on observed clerkship grade patterns. Predictors of group membership and predictive bias by race/ethnicity and sex were investigated.

METHOD

Using data from 6 medical student cohorts at Johns Hopkins University School of Medicine (JHUSOM), latent class analysis was used to classify students based on clerkship grades. Multinomial logistic regression was employed to investigate if preclerkship measures and student demographic characteristics predicted clerkship performance-level groups. Marginal effects for United States Medical Licensing Exam (USMLE) Step 1 scores were obtained to assess the predictive validity of the test on group membership by race/ethnicity and sex. Predictive bias was examined by comparing multinomial logistic regression prediction errors across racial/ethnic groups.

RESULTS

Three clerkship performance-level groups emerged from the data: low, middle, and high. Significant predictors of group membership were race/ethnicity, sex, and USMLE Step 1 scores. Black or African American students were more likely (odds ratio [OR] = 4.26) to be low performers than White students. Black or African American (OR = 0.08) and Asian students (OR = 0.41) were less likely to be high performers than White students. Female students (OR = 2.51) were more likely to be high performers than male students. Patterns of prediction errors observed across racial/ethnic groups showed predictive bias when using USMLE Step 1 scores to predict clerkship performance-level groups.

CONCLUSIONS

Disparities in clerkship grades associated with race/ethnicity were found among JHUSOM students, which persisted after controlling for USMLE Step 1 scores, sex, and other preclerkship performance measures. Differential predictive validity of USMLE Step 1 exam scores and systematic error predictions by race/ethnicity show predictive bias when using USMLE Step 1 scores to predict clerkship performance across racial/ethnic groups.

Neurodevelopmental and behavioral outcomes of very preterm infants: latent profile analysis in the Environmental influences on Child Health Outcomes (ECHO) Program

BACKGROUND

Very preterm infants are at high risk for neurodevelopmental impairments. We used a child-centered approach (latent profile analysis [LPA]) to describe 2-year neurobehavioral profiles for very preterm infants based on cognitive, motor, and behavioral outcomes. We hypothesized that distinct outcome profiles would differ in the severity and co-occurrence of neurodevelopmental and behavioral impairment.

METHODS

We studied children born <33 weeks' gestation from the Environmental influences on Child Health Outcomes Program with at least one neurobehavioral assessment at age 2 (Bayley Scales of Infant and Toddler Development, Child Behavior Checklist, Modified Checklist for Autism in Toddlers, cerebral palsy diagnosis). We applied LPA to identify subgroups of children with different patterns of outcomes.

RESULTS

In 2036 children (52% male; 48% female), we found four distinct neurobehavioral profiles. Most children (~85%) were categorized into one of two profiles characterized by no/mild neurodevelopmental delay and a low prevalence of behavioral problems. Fewer children (~15%) fell into one of two profiles characterized by severe neurodevelopmental impairments. One profile consisted of children (5%) with co-occurring neurodevelopmental impairment and behavioral problems.

CONCLUSION

Child-centered approaches provide a comprehensive, parsimonious description of neurodevelopment following preterm birth and can be useful for clinical and research purposes.

IMPACT

Most research on outcomes for children born very preterm have reported rates of impairment in single domains. Child-centered approaches describe profiles of children with unique combinations of cognitive, motor, and behavioral strengths and weaknesses. We capitalized on data from the nationwide Environmental influences on Child Health Outcomes Program to examine these profiles in a large sample of children born <33 weeks gestational age. We found four distinct neurobehavioral profiles consisting of different combinations of cognitive, motor, and behavioral characteristics. This information could aid in the development of clinical interventions that target different profiles of children with unique developmental needs.

Prevention and promotion effects of Self Help Plus: secondary analysis of cluster randomised controlled trial data among South Sudanese refugee women in Uganda

INTRODUCTION

Evidence-based and scalable prevention and promotion focused mental health and psychosocial support interventions are needed for conflict-affected populations in humanitarian settings. This study retrospectively assessed whether participation in Self Help Plus (SH+) versus enhanced usual care (EUC) resulted in reduced incidence of probable mental disorder and increased positive mental health and well-being post-intervention among South Sudanese refugee women in Uganda.

METHODS

This study used secondary data from treatment-oriented pilot (n=50) and fully-powered cluster randomised controlled trials (cRCT)s (n=694) of SH+ versus EUC. Data from baseline and post-intervention assessments were combined. A composite latent indicator for mental health problems was generated using mental health and well-being measures included in both cRCTs. In order to assess incidence, a binary variable approximating probable mental disorder was created to exclude those with probable mental disorder from the analysis sample and as the primary prevention outcome. The promotive effects of SH+ relative to EUC were examined in the same sample by assessing subjective well-being and psychological flexibility scale scores.

RESULTS

A single factor for mental health problems was identified with all factor loadings >0.30 and acceptable internal consistency (α=0.70). We excluded 161 women who met criteria for probable mental disorder at baseline. Among those with at least moderate psychological distress but without probable mental disorder at baseline and with follow-up data (n=538), the incidence of probable mental disorder at post-intervention was lower among those who participated in SH+ relative to EUC (Risk ratio =0.16, 95% CI: 0.05 to 0.53). Participation in SH+ versus EUC was also associated with increased subjective well-being (β=2.62, 95% CI: 1.63 to 3.60) and psychological flexibility (β=4.55, 95% CI: 2.92 to 6.18) at post-intervention assessment.

CONCLUSIONS

These results support the use and further testing of SH+ as a selective and indicated prevention and promotion focused psychosocial intervention in humanitarian settings.

Latent Class Analysis of Prenatal Substance Exposure and Child Behavioral Outcomes

OBJECTIVES

To predict behavioral disruptions in middle childhood, we identified latent classes of prenatal substance use.

STUDY DESIGN

As part of the Environmental influences on Child Health Outcomes Program, we harmonized prenatal substance use data and child behavior outcomes from 2195 women and their 6- to 11-year-old children across 10 cohorts in the US and used latent class-adjusted regression models to predict parent-rated child behavior.

RESULTS

Three latent classes fit the data: low use (90.5%; n = 1986), primarily using no substances; licit use (6.6%; n = 145), mainly using nicotine with a moderate likelihood of using alcohol and marijuana; and illicit use (2.9%; n = 64), predominantly using illicit substances along with a moderate likelihood of using licit substances. Children exposed to primarily licit substances in utero had greater levels of externalizing behavior than children exposed to low or no substances (P = .001, d = .64). Children exposed to illicit substances in utero showed small but significant elevations in internalizing behavior than children exposed to low or no substances (P < .001, d = .16).

CONCLUSIONS

The differences in prenatal polysubstance use may increase risk for specific childhood problem behaviors; however, child outcomes appeared comparably adverse for both licit and illicit polysubstance exposure. We highlight the need for similar multicohort, large-scale studies to examine childhood outcomes based on prenatal substance use profiles.

Assessment of Psychosocial and Neonatal Risk Factors for Trajectories of Behavioral Dysregulation Among Young Children From 18 to 72 Months of Age

Importance

Emotional and behavioral dysregulation during early childhood are associated with severe psychiatric, behavioral, and cognitive disorders through adulthood. Identifying the earliest antecedents of persisting emotional and behavioral dysregulation can inform risk detection practices and targeted interventions to promote adaptive developmental trajectories among at-risk children.

Objective

To characterize children's emotional and behavioral regulation trajectories and examine risk factors associated with persisting dysregulation across early childhood.

Design, Setting, and Participants

This cohort study examined data from 20 United States cohorts participating in Environmental influences on Child Health Outcomes, which included 3934 mother-child pairs (singleton births) from 1990 to 2019. Statistical analysis was performed from January to August 2022.

Exposures

Standardized self-reports and medical data ascertained maternal, child, and environmental characteristics, including prenatal substance exposures, preterm birth, and multiple psychosocial adversities.

Main Outcomes and Measures

Child Behavior Checklist caregiver reports at 18 to 72 months of age, with Dysregulation Profile (CBCL-DP = sum of anxiety/depression, attention, and aggression).

Results

The sample included 3934 mother-child pairs studied at 18 to 72 months. Among the mothers, 718 (18.7%) were Hispanic, 275 (7.2%) were non-Hispanic Asian, 1220 (31.8%) were non-Hispanic Black, 1412 (36.9%) were non-Hispanic White; 3501 (89.7%) were at least 21 years of age at delivery. Among the children, 2093 (53.2%) were male, 1178 of 2143 with Psychosocial Adversity Index [PAI] data (55.0%) experienced multiple psychosocial adversities, 1148 (29.2%) were exposed prenatally to at least 1 psychoactive substance, and 3066 (80.2%) were term-born (≥37 weeks' gestation). Growth mixture modeling characterized a 3-class CBCL-DP trajectory model: high and increasing (2.3% [n = 89]), borderline and stable (12.3% [n = 479]), and low and decreasing (85.6% [n = 3366]). Children in high and borderline dysregulation trajectories had more prevalent maternal psychological challenges (29.4%-50.0%). Multinomial logistic regression analyses indicated that children born preterm were more likely to be in the high dysregulation trajectory (adjusted odds ratio [aOR], 2.76; 95% CI, 2.08-3.65; P < .001) or borderline dysregulation trajectory (aOR, 1.36; 95% CI, 1.06-1.76; P = .02) vs low dysregulation trajectory. High vs low dysregulation trajectories were less prevalent for girls compared with boys (aOR, 0.60; 95% CI, 0.36-1.01; P = .05) and children with lower PAI (aOR, 1.94; 95% CI, 1.51-2.49; P < .001). Combined increases in PAI and prenatal substance exposures were associated with increased odds of high vs borderline dysregulation (aOR, 1.28; 95% CI, 1.08-1.53; P = .006) and decreased odds of low vs high dysregulation (aOR, 0.77; 95% CI, 0.64-0.92; P = .005).

Conclusions and Relevance

In this cohort study of behavioral dysregulation trajectories, associations were found with early risk factors. These findings may inform screening and diagnostic practices for addressing observed precursors of persisting dysregulation as they emerge among at-risk children.

Prenatal Antidepressant Exposures and Autism Spectrum Disorder or Traits: A Retrospective, Multi-Cohort Study

Prenatal antidepressant exposure has been associated with increased risk for neurodevelopmental disorders in childhood, including autism spectrum disorder (ASD). The current study utilized multi-cohort data from the Environmental influences on Child Health Outcomes (ECHO) program (N = 3129) to test for this association, and determine whether the association remained after adjusting for maternal prenatal depression and other potential confounders. Antidepressants and a subset of selective serotonin reuptake inhibitors (SSRIs) were examined in relation to binary (e.g., diagnostic) and continuous measures of ASD and ASD related traits (e.g., social difficulties, behavior problems) in children 1.5 to 12 years of age. Child sex was tested as an effect modifier. While prenatal antidepressant exposure was associated with ASD related traits in univariate analyses, these associations were statistically non-significant in models that adjusted for prenatal maternal depression and other maternal and child characteristics. Sex assigned at birth was not an effect modifier for the prenatal antidepressant and child ASD relationship. Overall, we found no association between prenatal antidepressant exposures and ASD diagnoses or traits. Discontinuation of antidepressants in pregnancy does not appear to be warranted on the basis of increased risk for offspring ASD.

Co-Occurring Mental Health Symptoms in Urban Adolescents: Comorbidity Profiles and Correlates

OBJECTIVE

To identify subgroups of urban youth based on their self- and teacher-reported mental health symptoms, and to explore characteristics of these subgroups.

METHODS

Cross-sectional data from 426 eighth-grade students (Mage = 13.22 years; 70.1% Black/African American; 58.7% female) across 20 Baltimore City public schools were analyzed using latent profile analysis and latent regressions. Variables for latent profile analysis included self-reported symptoms (i.e., anxiety, depression, trauma, interpersonal issues, social problems, and behavioral dysfunction) and teacher-reported symptoms (i.e., externalizing, internalizing, and problems in social and emotional competence). Regressions used profile membership to predict trauma exposure, coping mechanisms, and substance use.

RESULTS

A 3-profile solution was found from the latent profile analysis. The profile with high student- and teacher-reported symptoms had more trauma exposures, greater use of maladaptive coping mechanisms, and higher substance use.

CONCLUSIONS

The current study may help in the identification of urban youth who are at risk of developing multiple co-occurring psychological disorders to target for prevention efforts.

A call to create evidence-based mental health promotion interventions for youth that are equitable across ethnic/racial subgroups: Advocates 4-ALL Youth

Background

Adolescents from historically racial and ethnic minoritized and low-income communities have higher rates of early-life and chronic difficulties with anxiety and depression compared to non-Hispanic White youth. With mental health distress exacerbated during and in the wake of the COVID-19 pandemic, there is a need for accessible, equitable evidence-based programs that promote psychological well-being, strengthen one's ability to adapt to adversity, and build self-efficacy prior to adolescence.

Methods

An evidenced-based resiliency-focused health coaching intervention was adapted using a health equity implementation framework to meet the needs of a Title I elementary school in rural Alabama (AL) that serves over 80% Black and Hispanic students. To ensure that the program met local community needs while maintaining core program educational activities, all adaptations were documented utilizing a standard coding system.

Results

Leveraging an existing academic-community partnership with Auburn University and a local AL school district, a new program, Advocates 4-All Youth (ALLY), was created. Three major adaptations were required: (1) the use of local community volunteers (ALLYs) to deliver the program versus health coaches, (2) the modification of program materials to meet the challenge of varying levels of general and health-related literacy, and (3) the integration of the Empower Action Model to target protective factors in a culturally-tailored delivery to ensure key program outcomes are found equitable for all students.

Conclusion

With continued increases in youth mental health distress, there is a need for the development of universal primary prevention interventions to promote mental well-being and to strengthen protective factors among youth from historically disadvantaged backgrounds. ALLY was created to meet these needs and may be an effective strategy if deemed efficacious in improving program outcomes.

Immunologic profiling in schizophrenia and rheumatoid arthritis

The negative relationship between schizophrenia (SCZ) and rheumatoid arthritis (RA) has been observed for 85 years, but the mechanisms driving this association are unknown. This study analyzed differences in profiles of cytokines (IL-1β, IL-Ra, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12p70, IFNγ, TNFα), selected genes (HLA-DRB1, IL1RN, HP2), and antibodies related to gluten sensitivity (AGA-IgG, AGA-IgA), celiac disease (tTG), and systemic autoimmunity (ANA, anti-CCP, RF) in 40 subjects with SCZ, 40 with RA, and 40 healthy controls (HC). HLA-DRB1*04:01 alleles were enriched in persons with SCZ and RA compared with HC, and the HP2/HP2 genotype was 2-fold more prevalent in AGA/tTG-positive versus negative SCZ patients. Patients with SCZ demonstrated 52.5% positivity for any of the antibodies tested, compared to 90% of RA patients and 30% of HC. Cluster analysis of the cytokines revealed three clusters: one associated with SCZ marked by high levels of IL-1Ra, one associated with HC, and one associated with both SCZ and RA marked by elevated levels of IFNγ, TNFα, and IL-6. These analyses suggest that stratification of SCZ patients by cytokine profile may identify unique SCZ subgroups and enable the use of currently available cytokine-targeted treatment strategies.

Predictors of suicidal ideation trajectories in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study

A better understanding of suicidal ideation (SI), including patterns of SI, may help elucidate links between depression, SI, and suicidal behavior. This study sought to identify trajectories of SI in a large, community-based clinical trial of participants with major depressive disorder (MDD) and to investigate the relationships between these trajectories and predictors of interest, including anxiety and anhedonia. A longitudinal latent class analysis was conducted in 3923 participants enrolled in Level 1 of the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study of citalopram for the treatment of MDD. An unconditional latent class analysis was conducted using SI at study weeks 0, 2, 4, 6, and 9 as the indicators. A multinomial regression was then conducted with SI trajectory as the outcome and anhedonia, severity of depressive symptoms, atypical depression, anxiety, history of suicide attempt, history of substance abuse, history of trauma, and other covariates as the predictors. Four SI trajectories were identified: 1) variable SI; 2) little-to-no SI; 3) persistent SI; and 4) improving SI. Compared to the little-to-no SI trajectory, those with more severe anhedonia were more likely to experience persistent SI, while those with more severe anxiety were more likely to experience improving SI. Factors that distinguish SI trajectories, such as anxiety and anhedonia, may be critical targets for intervention or profiles for prognosis.

Characteristics of the autism spectrum disorder gastrointestinal and related behaviors inventory in children

Gastrointestinal (GI) symptoms are one of the prevalent co‐occurring issues in autism spectrum disorder (ASD), though the range of symptom frequency estimates varies dramatically across studies, which can limit the further research of GI issues in ASD as well as potential treatment strategies. The wide range of prevalence estimates is partly due to the lack of standardized, validated measures of GI symptoms among people with ASD. The goal of this study was to (1) develop a measure, which included non‐verbal and mealtime behaviors, to assess for GI symptoms and (2) evaluate its psychometric characteristics. This was accomplished by drawing on two existing tools, Autism Treatment Network Gastrointestinal Inventory and the Brief Autism Mealtime Behavior Inventory, and deriving new items, to create the “ASD Gastrointestinal and Related Behaviors Inventory” (ASD‐GIRBI). The ASD‐GIRBI was piloted in an online registry of families with a child with ASD. A psychometric analysis was carried out in a sample of 334 children aged 6–17 years with ASD, resulting in a 36‐item tool. The Cronbach's alpha for the overall scale was 0.88. Exploratory factor analysis identified a seven‐factor model (1. Bowel movement pain; 2. Aggressive or disruptive during mealtimes; 3. Particular with foods; 4. Abdominal pain and upset stomach; 5. Refusing food; 6. Constipation and encopresis; 7. Motor or other behaviors). Following validation in an independent sample with clinical evaluation of GI symptoms, this tool will be helpful for both research and clinical purposes.

Gastrointestinal (GI) symptoms are common in children with autism spectrum disorder (ASD), yet assessing these symptoms remains challenging. This study developed a parent‐report, 36‐item questionnaire to measure GI symptoms in children with ASD. The tool included questions about food, mealtimes, GI symptoms, bowel habits, and behavior. This questionnaire may help researchers and clinicians assess GI symptoms among children with ASD.

Measuring sexual violence stigma in humanitarian contexts: assessment of scale psychometric properties and validity with female sexual violence survivors from Somalia and Syria

BACKGROUND

Valid measures of sexual violence stigma that can be readily incorporated into program monitoring and evaluation systems are needed to strengthen gender-based violence (GBV) services in humanitarian emergencies. This study sought to assess the psychometric properties, construct validity, and measurement invariance of sexual violence stigma scales among female Somali GBV survivors in Kenya and Syrian GBV survivors in Jordan to identify an abbreviated scale that could be used across humanitarian contexts.

METHODS

We administered measures of sexual violence stigma to 209 female survivors of sexual violence aged 15 and older in Kenya and Jordan. Exploratory factor analysis was used to assess the underlying latent structure, and Item Response Theory was used to estimate item difficulty and discrimination parameters to guide efforts to shorten the scales. Differential item functioning (DIF) by site was assessed using Multiple Indicators, Multiple Causes models. Construct validity of the sexual violence stigma scales was assessed by estimating correlations with functional impairment, depression, and disability.

RESULTS

The sexual violence stigma measure exhibited distinct factor structures among Somali and Syrian GBV survivors. Among Somali survivors, a two-factor model with separate felt (10 items) and enacted (4 items) stigma constructs was identified, with scales for both domains exhibiting good internal consistency (Cronbach's alpha = 0.93 and 0.88, respectively). In Jordan, a single factor solution was uncovered for a 15-item stigma scale with good internal consistency (alpha = 0.86). The shortened core sexual stigma scale consisting of the 4 items that did not exhibit DIF had a Cronbach's alpha of 0.82 in Kenya and 0.81 in Jordan. The felt stigma scale in Kenya, the full stigma scale in Jordan, and abbreviated core stigma scales in both countries were meaningfully correlated with depression, while correlations with functional impairment were weaker and inconsistent across scales.

CONCLUSIONS

An abbreviated core set of invariant perceived and internalized sexual violence stigma items demonstrated evidence of construct validity in two diverse settings. The ability of this measure to be efficiently administered as a part of routine program monitoring and evaluation activities, with the potential addition of items from a measurement bank to improve contextual relevance, can facilitate improvements in the delivery and quality of gender-based violence programs in humanitarian emergencies.

Confirming Profiles of Comorbid Psychological Symptoms in Urban Youth: Exploring Gender Differences and Trait Mindfulness

Prior work has identified the need for replication of psychological research; however, validation efforts are rare. The purpose of the current study was to confirm latent profiles of comorbid psychological symptoms in an urban adolescent sample and examine differences in gender and trait mindfulness across these profiles. Cross-sectional data from 201 eighth grade students (63% female; M_age = 13.24; 86% Black) across nine Baltimore City public middle schools were analyzed. Confirmatory latent profile analyses showed that the previously-identified 3-profile solution with boundary constraints was the best fit for the data, and significant sex and trait mindfulness differences were identified. The current study supports the need for future replication studies using this methodology to improve theory and targeted interventions.

Exploring the evidence for epigenetic regulation of environmental influences on child health across generations

Environmental exposures, psychosocial stressors and nutrition are all potentially important influences that may impact health outcomes directly or via interactions with the genome or epigenome over generations. While there have been clear successes in large-scale human genetic studies in recent decades, there is still a substantial amount of missing heritability to be elucidated for complex childhood disorders. Mounting evidence, primarily in animals, suggests environmental exposures may generate or perpetuate altered health outcomes across one or more generations. One putative mechanism for these environmental health effects is via altered epigenetic regulation. This review highlights the current epidemiologic literature and supporting animal studies that describe intergenerational and transgenerational health effects of environmental exposures. Both maternal and paternal exposures and transmission patterns are considered, with attention paid to the attendant ethical, legal and social implications.

Florida's Opioid Crackdown and Mortality From Drug Overdose, Motor Vehicle Crashes, and Suicide: A Bayesian Interrupted Time-Series Analysis

In 2011, Florida established a prescription drug monitoring program and adopted new regulations for independent pain-management clinics. We examined the association of those reforms with drug overdose deaths and other injury fatalities. Florida's postreform monthly mortality rates-for drug-involved deaths, motor vehicle crashes, and suicide by means other than poisoning-were compared with a counterfactual estimate of what those rates would have been absent reform. The counterfactual was estimated using a Bayesian structural time-series model based on mortality trends in similar states. By December 2013, drug overdose deaths were down 17% (95% credible interval: -21, -12), motor vehicle crash deaths were down 9% (95% credible interval: -14, -4), and suicide deaths were unchanged compared with what would be expected in the absence of reform. Florida's opioid prescribing reform substantially reduced drug overdose deaths. Reforms may also have reduced motor vehicle crash deaths but were not associated with a change in suicides. More research is needed to understand these patterns. Bayesian structural time-series modeling is a promising new approach to interrupted time-series studies.

A randomized controlled trial of a trauma-informed school prevention program for urban youth: Rationale, design, and methods

INTRODUCTION

Youth in disadvantaged urban areas are frequently exposed to chronic stress and trauma, including housing instability, neighborhood violence, and other poverty-related adversities. These exposures increase risk for emotional, behavioral, and academic problems and ultimately, school dropout. Schools are a promising setting in which to address these issues; however, there are few universal, trauma-informed school-based interventions for urban youth.

METHODS/DESIGN

Project POWER (Promoting Options for Wellness and Emotion Regulation) is a randomized controlled trial testing the impact of RAP Club, a trauma-informed intervention for eighth graders that includes mindfulness as a core component. Students in 32 urban public schools (n = 800) are randomly assigned to either RAP Club or a health education active control group. We assess student emotional, behavioral, and academic outcomes using self-report surveys and teacher ratings at baseline, post-intervention, and 4-month follow up. Focus groups and interviews with students, teachers, and principals address program feasibility, acceptability, and fidelity, as well as perceived program impacts. Students complete an additional self-report survey in ninth grade. Schools provide students' academic and disciplinary data for their seventh, eighth, and ninth grade years. In addition, data on program costs are collected to conduct an economic analysis of the intervention and active control programs.

DISCUSSION

Notable study features include program co-leadership by young adults from the community and building capacity of school personnel for continued program delivery. In addition to testing program impact, we will identify factors related to successful program implementation to inform future program use and dissemination.

P1748 Left atrial diastolic and systolic functions modulate the response to the standardised Valsalva maneuver in normal subjects

Background

Although the Valsalva maneuver (VM) is being advocated by current guidelines to identify with echocardiography patients with increased left ventricular (LV) filling pressures using a decrease in mitral E/A velocity &gt; 0.5 as cutoff, there are limited published data for both patients and the normal response to the maneuver in healthy subjects.

Purpose

To assess LV and left atrial (LA) physiology during a standardized VM (VMs) in normal subjects.

Methods

The VMs was performed in 50 healthy subjects (M:F 38:12; age 40 ± 12 y.; HR 70 ± 11 bpm; BSA 1.81 ± 11 m2), instructed to forcefully exhale for 20 seconds without an initial deep breath into a tube connected to a sphygmomanometer, maintaining a 25-35 mmHg pressure. The VM was repeated 2 times at 5 minute intervals to record sequentially in the apical 4-chamber view: 1. LV and LA volumes; 2. Transmitral flow velocities. LA diastolic reservoir function (LAres) was calculated as: (maximum – minimum volume) / minimum volume x 100. Results. During the VMs, in all subjects LV indexed end-diastolic (-14 ± 7 ml/m2, -31 ± 15 %) and end-systolic (-6 ± 4 ml/m2, -31 ± 18 %) volumes, and stroke volume index (-9 ± 5 ml/m2, -30 ± 15 %) decreased similarly with unchanged LV ejection fraction %, and LA maximum and minimum volume indices both decreased (respectively -8 ± 6 ml/m2, -3 ± 3 ml/m2;-32 ± 25 %) with high variability. Mitral peak E velocity also decreased (-22 ± 13 cm/s, -27 ± 14 %) in all subjects, whereas peak A velocity change varied, such that a "pseudo-abnormal" decrease of E/A &gt; 0.5 was seen in 18 subjects (37 %). At baseline, this subgroup had lower heart rate (66 ± 11 vs 73 ± 10 bpm, p= .026), higher LAres (193 ± 67 vs 145 ± 47 %, p= .006), lower peak A velocity (50 ± 12 vs 58 ± 12 cm/s, p= .04) and higher E/A (1.8±.6 vs 1.4±.3, p= .004). During VMs, LV and LA volumes decreased similarly in all subjects, but increase in heart rate was higher (12 ± 8 vs 6 ± 5 bpm, p= .023), and peak A wave increased instead of decreasing (20 ± 20 % vs -8 ± 18 %, p&lt; .001) in the subjects with "pseudo-abnormal" decrease of E/A. During VMs, decrease in E/A was mainly determined (regression analysis, r: .76, p= .029) by baseline LAres (B= -.71) and change in LAres during VMs (B= -.47), whereas an increase in peak A velocity (r: .46, p= .031) was mainly determined by degree of HR increase (B= .41) and baseline LV EF (B= .3).

Conclusions

During VMs, a "pseudo-abnormal" decrease of the E/A velocity ratio is present in almost 40 % of normal subjects, and is determined by the interplay of the baseline diastolic compliance and the increase in systolic function of the LA during VM. These results may influence the accuracy of the VMs in the detection of increased LV filling pressures in patients.

Teacher Mental Health Literacy is Associated with Student Literacy in the Adolescent Depression Awareness Program

The Adolescent Depression Awareness Program, developed by psychiatrists and psychiatric nurses at the Johns Hopkins University School of Medicine, is a depression literacy program delivered to high school students by teachers. This mode of delivery represents an effective and sustainable way to increase awareness of mental health, reduce stigma, improve early detection, and facilitate help-seeking behavior among adolescents. The present study explores the depression literacy and stigma of teachers and their students. Survey responses of 66 teachers and 6679 high school students about depression literacy and stigma pre- and post-education intervention were analyzed using a multilevel model fit in Mplus. Teacher depression literacy was significantly associated with student depression literacy [β = 0.199, SE = 0.095, p = 0.035, 95% CI (0.044, 0.355)] at the post-assessment, but was not associated with student stigma. Teacher stigma was not significantly related to student depression literacy or stigma in the post-assessment. These findings highlight the importance of optimizing teacher depression literacy in order to maximize student depression literacy while also diminishing concerns about the transmission of stigmatized beliefs from teachers to students.

Longitudinal depressive and anxiety symptoms of adult injury patients in Kenya and their risk factors

Background: Injuries account for a significant proportion of the health and economic burden for populations in low- and middle-income countries. However, little is known about psychological distress trajectories amongst injury survivors in low- and middle-income countries.Methods: Adult injury patients (n = 644) admitted to Kenyatta National Hospital in Nairobi, Kenya, were enrolled and interviewed in the hospital, and at 1, 2-3, and 4-7 months after hospital discharge through phone to assess depressive and anxiety symptoms and level of disability. Growth mixture modeling was applied to identify latent trajectories of depressive and anxiety symptoms.Results: Elevated depressive and moderate-level anxiety symptoms (13%) and low depressive and anxiety symptoms (87%) trajectories were found between hospitalization and up to seven months after hospital discharge. Being female, prior trauma experience, longer hospitalization, worse self-rated health status while in the hospital, and lack of monetary assistance during hospitalization were associated with the elevated symptoms trajectory. The higher symptoms trajectory associated with higher disability levels after hospital discharge and significantly lower proportion of resuming daily activities and work.Conclusion: The persistence of elevated depressive symptoms and associated reduced functioning several months after physical injury underscores the importance of identifying populations at risk for preventive and early interventions.Implications for RehabilitationHealth providers following up with injury survivors should screen for depressive and anxiety symptomsSpecial attention to women and people with a potential traumatic exposure historyIncorporation of evidence-based culturally adapted psychosocial interventions in rehabilitation and outpatient clinics.

Trauma Exposure, Posttraumatic Stress Disorder Symptoms Trajectory, and Disability Level Among Hospitalized Injury Survivors in Kenya

Potentially traumatic events (PTEs) have been consistently associated with posttraumatic stress disorder (PTSD). However, the extent of association and attribution to subsequent disability has varied, with limited studies conducted in urban low-income contexts. This longitudinal study estimated the trajectory of PTSD symptoms up to 7 months after hospitalization and the associated disability level among adult patients who had been hospitalized due to injury. Adult injury patients (N = 476) admitted to Kenyatta National Hospital in Nairobi, Kenya, were interviewed in person in the hospital, and via phone at 1, 2-3, and 4-7 months after hospital discharge. Using latent growth curve modeling, two trajectories of PTSD symptoms emerged: (a) persistently elevated PTSD symptoms (9.2%), and (b) low PTSD symptoms (90.8%). Number of PTEs experienced remained moderately associated with the elevated trajectory after controlling for in-hospital depressive symptoms. Having previously witnessed killings or serious injuries, AOR = 2.32, 95% CI [1.07, 5.05]; being female, AOR = 4.74, 95% CI [4.53, 4.96]; elevated depressive symptoms during hospitalization, AOR = 2.96, 95% CI [1.28, 6.83]; and having no household savings/assets, AOR = 1.28, 95% CI [1.13, 1.44], were associated with the elevated PTSD symptoms trajectory class after controlling for other risk factors. Latent membership in the elevated PTSD trajectory was associated with a significantly higher level of disability several months after hospital discharge, p < .001, after controlling for injury and demographic characteristics. These results underline the associations among in-hospital depressive symptoms, witnessing atrocities, and poverty, and an elevated PTSD symptoms trajectory.

The Synergistic Impact of Sexual Stigma and Psychosocial Well-Being on HIV Testing: A Mixed-Methods Study Among Nigerian Men who have Sex with Men

Although sexual stigma has been linked to decreased HIV testing among men who have sex with men (MSM), mechanisms for this association are unclear. We evaluated the role of psychosocial well-being in connecting sexual stigma and HIV testing using an explanatory sequential mixed methods analysis of 25 qualitative and 1480 quantitative interviews with MSM enrolled in a prospective cohort study in Nigeria from March/2013-February/2016. Utilizing structural equation modeling, we found a synergistic negative association between sexual stigma and suicidal ideation on HIV testing. Qualitatively, prior stigma experiences often generated psychological distress and perceptions of feeling unsafe, which decreased willingness to seek services at general health facilities. MSM reported feeling safe at the MSM-friendly study clinic but still described a need for psychosocial support services. Addressing stigma and unmet mental health needs among Nigerian MSM has the potential to improve HIV testing uptake.

Critical Issues in the Inclusion of Genetic and Epigenetic Information in Prevention and Intervention Trials

Human genetic research in the past decade has generated a wealth of data from the genome-wide association scan era, much of which is catalogued and freely available. These data will typically test the relationship between a single nucleotide variant or polymorphism (SNP) and some outcome, disease, or trait. Ongoing investigations will yield a similar wealth of data regarding epigenetic phenomena. These data will typically test the relationship between DNA methylation at a single genomic location/region and some outcome. Most of these findings will be the result of cross-sectional investigations typically using ascertained cases and controls. Consequently, most methodological consideration focuses on methods appropriate for simple case-control comparisons. It is expected that a growing number of investigators with longitudinal experimental prevention or intervention cohorts will also measure genetic and epigenetic indicators as part of their investigations, harvesting the wealth of information generated by the genome-wide association study (GWAS) era to allow for targeted hypothesis testing in the next generation of prevention and intervention trials. Herein, we discuss appropriate quality control and statistical modelling of genetic, polygenic, and epigenetic measures in longitudinal models. We specifically discuss quality control, population stratification, genotype imputation, pathway approaches, and proper modelling of an interaction between a specific genetic variant and an environment variable (GxE interaction).

The Association of School Climate, Depression Literacy, and Mental Health Stigma Among High School Students

BACKGROUND

Although school climate is linked with youth educational, socioemotional, behavioral, and health outcomes, there has been limited research on the association between school climate and mental health education efforts. We explored whether school climate was associated with students' depression literacy and mental health stigma beliefs.

METHODS

Data were combined from 2 studies: the Maryland Safe Supportive Schools Project and a randomized controlled trial of the Adolescent Depression Awareness Program. Five high schools participated in both studies, allowing examination of depression literacy and stigma measures from 500 9th and 10th graders. Multilevel models examined the relationship between school-level school climate characteristics and student-level depression literacy and mental health stigma scores.

RESULTS

Overall school climate was positively associated with depression literacy (odds ratio [OR] = 2.78, p < .001) and negatively associated with stigma (Est. = -3.822, p = .001). Subscales of engagement (OR = 5.30, p < .001) and environment were positively associated with depression literacy (OR = 2.01, p < .001) and negatively associated with stigma (Est. = -6.610, p < .001), (Est. = -2.742, p < .001).

CONCLUSIONS

Positive school climate was associated with greater odds of depression literacy and endorsement of fewer stigmatizing beliefs among students. Our findings raise awareness regarding aspects of the school environment that may facilitate or inhibit students' recognition of depression and subsequent treatment-seeking.

The dynamic epigenome and its implications for behavioral interventions: a role for epigenetics to inform disorder prevention and health promotion

The emerging field of behavioral epigenetics is producing a growing body of evidence that early life experience and social exposure can alter the way by which genes are marked with DNA methylation. We hypothesize that changes in DNA methylation as well as other epigenetic markers could generate stable phenotypes. Early life adversity appears to result in altered DNA methylation of genes in the brain and peripheral tissues, and these changes are associated with adverse phenotypic changes. Although the data are still sparse, early epigenetic studies have provided a proof of principle that experiences and the environment leave marks on genes, and thus suggest molecular and physical mechanisms for the epidemiological concept of gene-environment interaction. The main attraction of DNA methylation for type I (TI) translational prevention science is the fact that, different from genetic changes that are inherited from our ancestors, DNA methylation is potentially preventable and reversible and, therefore, there is a prospect of epigenetically targeted interventions. In addition, DNA methylation markers might provide an objective tool for assessing effects of early adverse experience on individual risks as well as providing objective measures of progress of an intervention. In spite of this great potential promise of the emerging field of social and translational epigenetics, many practical challenges remain that must be addressed before behavioral epigenetics could become translational epigenetics.

Video Gaming in a Hyperconnected World: A Cross-sectional Study of Heavy Gaming, Problematic Gaming Symptoms, and Online Socializing in Adolescents

AIMS

Examining online social interactions along with patterns of video gaming behaviors and game addiction symptoms has the potential to enrich our understanding of disorders related to excessive video game play.

METHODS

We performed latent class analysis in a sample of 9733 adolescents based on heavy use of games, social networking and instant messaging, and game addiction symptoms. We used latent class regression to determine associations between classes, psychosocial well-being and friendship quality.

RESULTS

We identified two types of heavy gaming classes that differed in probability of online social interaction. Classes with more online social interaction reported fewer problematic gaming symptoms than those with less online social interaction. Most adolescents estimated to be in heavy gaming classes had more depressive symptoms than normative classes. Male non-social gamers had more social anxiety. Female social gamers had less social anxiety and loneliness, but lower self-esteem. Friendship quality attenuated depression in some male social gamers, but strengthened associations with loneliness in some male non-social gamers.

CONCLUSIONS

In adolescents, symptoms of video game addiction depend not only on video game play but also on concurrent levels of online communication, and those who are very socially active online report fewer symptoms of game addiction.

ADHD and Suicidal Ideation: The Roles of Emotion Regulation and Depressive Symptoms Among College Students

OBJECTIVE

ADHD appears to increase risk for both depression and suicidal ideation, while ADHD and depression are also associated with emotion regulation deficits. Thus, we evaluated the degree to which depression mediated the association between ADHD and suicidal ideation, as well as the degree to which emotion regulation deficits moderated the association ADHD shared with depression and suicidal ideation in a nonclinical sample.

METHOD

Participants were undergraduate psychology students (N = 627; age: M = 20.23, SD = 1.40; 60% female; 47% European American) who completed an online assessment.

RESULTS

Results indicated that ADHD indirectly increased suicidal ideation through depression. Emotion regulation deficits of accepting negative emotions, emotional awareness, and goal-oriented behavior moderated the indirect effect of ADHD on suicidal ideation.

CONCLUSION

Depression appears to play an important mediating role in suicidal ideation for college students with ADHD, and specific emotion regulation deficits appear to amplify the effects of ADHD on depression and suicidal ideation.

Smoking quit success genotype score predicts quit success and distinct patterns of developmental involvement with common addictive substances

Genotype scores that predict relevant clinical outcomes may detect other disease features and help direct prevention efforts. We report data that validate a previously established v1.0 smoking cessation quit success genotype score and describe striking differences in the score in individuals who display differing developmental trajectories of use of common addictive substances. In a cessation study, v1.0 genotype scores predicted ability to quit with P=0.00056 and area under receiver-operating characteristic curve 0.66. About 43% vs 13% quit in the upper vs lower genotype score terciles. Latent class growth analyses of a developmentally assessed sample identified three latent classes based on substance use. Higher v1.0 scores were associated with (a) higher probabilities of participant membership in a latent class that displayed low use of common addictive substances during adolescence (P=0.0004) and (b) lower probabilities of membership in a class that reported escalating use (P=0.001). These results indicate that: (a) we have identified genetic predictors of smoking cessation success, (b) genetic influences on quit success overlap with those that influence the rate at which addictive substance use is taken up during adolescence and (c) individuals at genetic risk for both escalating use of addictive substances and poor abilities to quit may provide especially urgent focus for prevention efforts.

Objectively measured physical activity levels of Venetian adults

AIM

Venice, Italy, provides a unique environment to study physical activity as there are no automobiles, and walking is the most common means of transportation. The purpose of the present investigation was to objectively assess the physical activity (PA) levels of residents in Venice, Italy, using an accelerometer.

METHODS

Twenty-seven Venetians (12 men and 15 women, 48 ± 16 yr, 169.4 ± 6.6 cm, 71.7 ± 11.1 kg) had worn an accelerometer (Lifecorder Ex) for 7 consecutive days in order to determine daily number of steps, time spent in light (LPA), moderate (MPA), or vigorous intensity (VPA) and moderate to vigorous intensity (MVPA) as well as energy expenditure associated with PA (PAEE). The time for all PA and MVPA lasting at least 1 minute, 3 minutes, 5 minutes and 10 minutes were also assessed.

RESULTS

The PAEE, number of steps, LPA, MPA, VPA and MVPA averaged over 7 days of week were 1575 ± 524 kJ∙day⁻¹, 11920 ± 3667 steps∙day⁻¹, 77 ± 23 min∙day 43 ± 19 min∙day⁻¹, and 45 ± 21 min∙day⁻¹. The time for MVPA lasting >10 min was 0.3 ± 0.9 min∙day⁻¹.

CONCLUSION

The amount and intensity of PA in Venetian adults is substantially higher than in most other populations previously evaluated, particularly American adults. The effects of the highly active Venetian lifestyle on important health outcomes remain unclear, but warrant further investigation.

Extracorporeal lithotripsy in ureteral stones: Our experience with Dornier HM3, EDAP LT02, Piezolith 2300 lithotripters

We present our experience with three different lithotriptors: Dornier HM3, EDAP LT02 and Piezolith 2300. Materials and methods: 1876 patients with ureteral stones were treated between 1 January 1988 and 1 January 1996. The above 3 lithotriptors were used. In 925 patients the stones were located in the upper ureter, in 182 in the middle ureter and in 769 in the pelvic ureter. Auxiliary procedures were performed in 37% of patients. A DJ stent was used to catheterise 299 (16%) patients and a nephrostomy was performed in 19 (1%). Catheterisation was carried out in 247 (13.1%) ureters to localise the stones, plus 83 (4.4%) push ups and 52 (2.7%) Dormia baskets. Results: one treatment was sufficient in 1395 (74.3%) patients, 2 treatments in 335 (29.1%), 3 in 114 (6%), 4 in 21 (1.1%), 5 in 10 (0.5%) and 6 in 1 (0.05%). Patients were considered stone-free when they had negative X-ray and sonography two months after treatment; stones smaller than 3 mm, capable of being spontaneously eliminated without retrograde dilatation, were considered as fragments. The results were 1475 (78.6%) stone-free patients, 246 (13.1%) with fragments and 117 (6.2%) failures. 38 patients failed to appear at follow-up. Complications: complications were considered as hyperpyrexia and colics. There was very little hematuria, which regressed spontaneously in any case within the first 24 hours. Conclusion: side effects were few and required no treatment, so in our experience lithotripsy is the first choice treatment for ureteral stones. Particular attention, however, must be paid to the size of the stone in predicting the number of treatments.

Reversal of clinical resistance to LHRH analogue in metastatic prostate cancer by the pineal hormone melatonin: efficacy of LHRH analogue plus melatonin in patients progressing on LHRH analogue alone

OBJECTIVE

Experimental and preliminary clinical studies have suggested that the pineal hormone melatonin (MLT) may stimulate hormone receptor expression on both normal and cancer cells. Moreover, MLT has appeared to inhibit the growth of some cancer cell lines, including prostate cancer, either by exerting a direct cytostatic action, or by decreasing the endogenous production of some tumor growth factors, such as prolactin (PRL) and insulin-like growth factor-1 (IGF-1). On this basis, a study was carried out to evaluate the clinical efficacy of a neuroendocrine combination consisting of the LHRH analogue triptorelin plus MLT in metastatic prostate cancer progressing on triptorelin alone.

MATERIAL AND METHODS

The study including 14 consecutive metastatic prostate cancer patients with poor clinical conditions (median age: 70.5 years; median PS: 50%), refractory or resistant to a previous therapy with the LHRH analogue triptorelin alone. Triptorelin was injected i.m. at 3.75 mg every 28 days, and MLT was given orally at 20 mg/day in the evening every day until progression, starting 7 days prior to triptorelin.

RESULTS AND CONCLUSIONS

A decrease in PSA serum levels greater than 50% was obtained in 8/14 (57%) patients. Moreover, PSA mean concentrations significantly decreased on therapy of triptorelin plus MLT. In addition, a normalization of platelet number was obtained in 3/5 patients with persistent thrombocytopenia prior to study. Mean serum levels of both PRL and IGF-1 significantly decreased on therapy. Finally, a survival longer than 1 year was achieved in 9/14 (64%) patients. This preliminary study would suggest that the concomitant administration of the pineal hormone MLT may overcome the clinical resistance to LHRH analogues and improve the clinical conditions in metastatic prostatic cancer patients.

[Prognostic predictive factors of the clinical response to immunotherapy with subcutaneous interleukin-2, in patients with metastatic renal carcinoma: analysis of 60 cases]

The intravenous immunotherapy with high-dose interleukin-2 (IL-2) would constitute one of the most effective treatments of metastatic renal cell carcinoma (RCC). More recently, IL-2 subcutaneous therapy has also appeared active, either alone or in association with interferon, with results comparable to those found with the intravenous route of injection, but with a lower toxicity. On this basis, we have designed a protocol of treatment with low-dose IL-2 alone given subcutaneously as a first or a second line therapy in metastatic RCC. The study included 60 consecutive patients (pts) (M/F: 39/21, median age 56 years, range 26/74). IL-2 was given at a dose of 3 millions IU twice/day for 5 days/week, for 6 weeks, corresponding to one cycle. In non progressed pts a second cycle was repeated after a 28-day rest period. Dominant metastasis sites were, as follows: soft tissues: 8; bone: 11; lung: 29; liver: 3; liver plus lung: 7; adrenal: 2. The minimum follow-up was 18 months and the median follow-up was 34 months (range 18-48). A complete response (CR) was achieved in 2/60 (3%) pts. A partial response (PR) was obtained in 15/60 (25%). Therefore, tumor objective rate (CR + PR) was 17/60 (28%). The median duration of response was 13 months (4-33).(ABSTRACT TRUNCATED AT 250 WORDS)

[Terazosin in the treatment of benign prostatic hypertrophy]

Benign prostatic hypertrophy provokes clinical manifestations correlated on one hand to a static obstructive component, due to the increase in glandular size, and on the other hand to a dynamic component, controlled by the alpha adrenergic autonomic system which gives the smooth muscular tonus of the prostatic adenoma. The alpha adrenergic receptor block reduces the dynamic component, improves the clinical and urodynamic parameters determined by the infra-bladder obstruction in patients with BPH. The selective alpha 1, long acting antagonists especially, such as terazosin, offer a safe and efficient therapy for selected patients suffering from BPH. They also have the indisputable benefit of mono-administration. In this study the basic concepts of BPH treatment with terazosin are discussed.

Neurogenic urinary dysfunction in AIDS patients

From May 1992 to December 1993 (17 months), 18 patients with AIDS, 15 male and 3 female, age range from 25 to 50, were found to have severe voiding disorders related to neurogenic bladder dysfunction. All patients underwent neurologic, urologic and immunologic evaluation and were staged as AIDS-IVB. The neurological evaluation demonstrated: cryptococcal abscess of the brain in 1 patient, progressive and diffuse leukoencephalopathy in 3 patients, AIDS Dementia Complex in 3 patients and no neurologic abnormalities in 11 patients. The urodynamic tests demonstrated: detrusor areflexia in 5 patients, detrusor hyperreflexia with external sphincter dyssynergia in 5 patients, detrusor hyperreflexia with external sphincter dyssynergia and vesico-ureferai reflux in 1 patient, detrusor hyperreflexia without dyssynergia in 7 patients.

[Andrological complications after pancystoprostatovesiculectomy surgery: utility of the bulbocavernosus reflex]

The technique for radical cystoprostatectomy was modified to avoid injury to the branches of pelvic plexus that innervate the corpora cavernosa (monolateral neurovascular bundle preservation or "Nerve sparing technique"). The studies of Walsh and coll. demonstrated that the branches of pelvic plexus that innervate the corpora cavernosa are situated between the rectum and urethra and penetrate the urogenital diaphragm near to the muscular wall of the urethra. Injuries to the pelvic plexus can occur during 1) division of posterior pedicle of bladder (the seminal vesicle can be used as a landmark intraoperatively to avoid injury to pelvic plexus), 2) during apical dissection of prostate with transection of the urethra. The return of sexual function postoperatively is related to preservation of autonomic innervation; the excision of the neurovascular bundle on one side may prevent impotence in 68% patients. Our study was undertaken to identify the cause of impotence in men undergoing radical cystoprostatectomy with "Nerve sparing technique" using bulbo cavernous reflex. Our results suggest that bulbo cavernosus reflex may not be a sensitive clinical tool to establish a diagnosis of neurogenic erectile dysfunction after pelvic surgery. The Authors examine the recent neuro-uro-physiological diagnostic methods for the study of neurogenic erectile dysfunction.

Trattamento con laser infrarosso endouretrale delle prostatiti croniche abatteriche riacutizzate

The Authors present a new infrared laser device with endourethral atraumatic optic fiber capable of effectively treating patients with newly acute chronic prostatitis. Cost-benefit ratio is excellent and the method is minimally invasive.

Le basi anatomiche della prevenzione dei danni neurogeni in corso di chirurgia radicale pelvica nella donna

Radical pelvic surgery in women is considerably handicapped by serious neurogenic complications, commonly due to lesions in the inferior hypogastric plexus or its branches, which cannot be easily identified in the female pelvic cavity. The pelvic cavities of 42 adult female cadavers were studied and the relations between the nervous structures and the cardinal and utero-sacral ligaments were analysed. The possibility of identifying and recognising in vivo anatomical findings of the pelvic plexus is the fulcrum of nerve sparing pelvic surgery.

[Intracavitary echography with a 12.5 MHz microprobe: a new study method in the pathology of the urinary tract]

Endoluminal sonography performed with 12.5 MHz miniature transducer-containing catheters with diameter of 6 or 9 Fr., is a new technique for the study of urinary tract. We studied: U.S. scan of 10 corpes and 10 operatory specimens (bladders and kidneys) with anatomic measurement in vitro. U.S. scan of 20 patients "in vivo" with pathologies involving bladder and upper urinary tract. We studied the normal anatomy of bladder and ureter by U.S. and we detected the structures beyond the ureteral lumen as: vessels, lymph nodes, muscle. Our indications for the utility of this new U.S. technique are: Detection and staging of superficial T.C.C. of the bladder. Detection of dangerous vessels near the U.P.F before endopielotomy. Excretory tract minus (endoluminal ultrasound is helpful in differentiating such pelvic filling defects as blood clots, no opaque stones and transitional cell carcinoma).

[Pathology of urologic importance associated with acquired immunodeficiency syndrome]

Infection by the HIV virus affects the urogenital system in a minor percentage of cases in comparison to other organs such as the lungs, the central nervous system and the haemolymphopoietic system. In recent years however, with the continued spread of the disease also urologists find themselves dealing with the various urogenital pathologies that are presented in seropositive or fully-blown Aids patients. The Authors present their experience and describe the problems correlated to the dealing with acquired immune deficiency syndrome patients that are affected with urogenital pathologies.

Kidney and Ureteral Disease during HIV Infection

Infection by Hiv virus affects the urogenital system in a minor percentage of cases in comparison to other organs such as the lungs, the central nervous system and the haemolymphopoietic system. In recent years however, with the continued spread of the disease, also urologists find themselves dealing with various urogenital pathologies that are presented in seropositive or fully-blown Aids patients. The Authors present their experience and describe the problems correlated to dealing with acquired immunodeficiency syndrome patients that are affected with urological pathologies.

The use of echo-doppler in the study of renal damage sustained during percutaneous manoeuvres and extracorporeal lithotriptic treatments

The echo-doppler is a non-invasive diagnostic method that makes evaluation of the morphology and the renal intraparenchymal vessel flow possible. Due to the development and spread of percutaneous methods and to the large number of patients who undergo extracorporeal lithotripsy, the renal parenchyma suffers traumas of which neither the short no long term consequences are yet fully understood. We calculated the Resistive Index using echo-doppler in 10 pts. who underwnt extracorporeal lithotripsy and we looked for the possible presence of arteriovenous fistulae in 10 pts. who underwent percutaneous manoeuvres (nephrostomy, litholapaxy and endopyelotomy). The results showed an increased R.I. in all patients at the end of the treatment, and in only one patient was this elevated R.I. maintained at the follow-up after 30 days. Arteriovenous fistulae were not found in any of the other patients.

Semi conductor lasers in the treatment of benign prostate pathologies

Treatment of benign prostate pathology often has no effect on the symptomatology of the patient. For this reason we used an infrared laser ray, of which the biophysical effects on tissue are well noted: stimulation of lymphatic drainage, pain reduction, microcirculation, trophism and tissue elasticity increase. The laser was used on the prostate via an endorectal probe that gave compactness and orthogonality to the ray that is transmitted along 5 optic fibres. Between January 1991 and January 1992 we treated, following a rigorous enforcement of the requirements of the inclusion protocol, 80 patients with ages ranging from 25 to 77 years. Of these 40 suffered from abacterial chronic prostatitis (ACP), and 40 from early symptomatic benign prostatic hypertrophy (BPH) with a prostate diameter of < 4 cm. The preliminary results (with a 3 month follow-up) were satisfactory especially regarding the subjective symptomatology: BPH 75%; ACP 85%. The advantages of this method are: good results in selected cases (follow-up still limited), complete harmlessness, high tolerability, possibility of repeating the treatment, excellent cost-benefit ratio. The limitations are: exclusion from the protocol of neurologic bladders, bladder stones, median lobe of the prostate and the progressive loss of efficiency with the growth of the prostatic diameter.

[Recurrence of acute lymphoid leukemia in the bladder: a rare cause of bilateral hydronephrosis]

While the invasion of the bladder by neoplastic cells during acute lymphatic leukaemia in children has been reported by various authors, the leukaemic invasion of the bladder in adults is extremely rare. We report a case of recurrence of A.L.L. in the bladder presenting colicky symptomatology and obstruction of the excretory tracts.

[Traumatic injuries++ of the external genitalia: a case of avulsion of the penile skin]

The Authors report their recent experience about a penis trauma with a subtotal organ skinning. After the literature analysis, the AA. explain the case, with a particular attention to the surgical repairing technique. The surgical outcomes are discussed and it is re-marked the necessity of a precise diagnostic approach and follow up, also to prevent possible unerectional chains.

[Penile metastasis of prostatic carcinoma: a case report]

Penile metastases are uncommon lesions: most often secondary to a primary pelvic cancer (prostate, bladder and rectum) they have a unfavourable prognosis. The appearance of disseminations is still controversial and there is not an efficacious therapy. Priapism may be present or not. The Authors report their experience on a penile metastasis secondary to prostatic cancer and about the evolution of this pathology. A review of the Literature is done.
