Developing bilateral and spatial concepts in primary school-aged children: An empirical evaluation of the Anker Bilateral Spatial System

Background: Visual-spatial and visual-motor perceptual difficulties contribute to school-aged learning problems. Hence, a need exists to address children’s visual-spatial and visual-motor perceptual difficulties as early as possible in the child’s school career. Thus, this study reports on the evaluation of the Anker Bilateral Spatial System’s (ABSS) effectiveness in remediating primary school children’s perceptual difficulties. Method: Thirty-one children (17 boys and 14 girls) aged 6 to 12 years who had been identified by their classroom teacher as having observable visual-spatial and visual-motor perceptual difficulties participated in a 10-week pre/posttest intervention study. The study’s pre/posttest assessments included the Developmental Test of Visual-Motor Integration (VMI), the Spatial Awareness Skills Program Test (SASP), and two subscales of the School Function Assessment (SFA). Results: Paired t-test statistics were calculated on the pre/post intervention scores. Paired t-test statistics calculated (p = .05) that significant change had occurred in the writing speed (t = -3.978, p \u3c .001). Conclusion: Given that the study’s Year 1 students made progress in more areas of remediation than did any other year level, it is evident that the ABSS is particularly effective with this year grou

Community Violence Exposure and Positive Youth Development in Urban Youth

Youth in urban environments are exposed to community violence, yet some do well and continue on a positive developmental trajectory. This study investigated the relationships between lifetime community violence exposure (including total, hearing about, witnessing, and victimization), family functioning, and positive youth development (PYD) among 110 urban youth ages 10-16 years (54% female) using a paper and pen self-report survey. This cross-sectional study was part of an interdisciplinary community-based participatory research effort in West/Southwest Philadelphia. Almost 97% of the sample reported some type of community violence exposure. Controlling for presence of mother in the home and presence of father in the home, separate linear regression models for PYD by each type of community violence exposure indicated that gender and family functioning were significantly associated with PYD. None of the types of community violence exposure were significant in the models. Significant interactions between gender and presence of mother in the home and gender and family functioning helped better explain these relationships for some of the types of community violence exposure. Presence of mother was associated with higher PYD for girls, but not for boys. Boys with poor family functioning had lower PYD than girls with poor family functioning. This study helps to better delineate relationships between CVE and PYD by adding new knowledge to the literature on the role of family functioning. Points of intervention should focus on families, with attention to parental figures in the home and overall family functioning

Journey Towards Recovery Following Physical Trauma

Convalescence and recovery following illness are of central importance to nursing. These themes have been explored increasingly in the literature. The focus, however, has been primarily on the process of integrating chronic illness into one’s life. Recovery from physical injury is rarely addressed. A body of work focusing on physical trauma demonstrates that recovery is often not complete after injuries that have not been viewed as disabling. To illuminate understanding of recovery following physical trauma, the purpose of our 1997 study was to describe more thoroughly the nature of recovery. A total of 63 adults, in a convenience sample, who survived serious physical trauma, were interviewed 2·5 years after injury using an open-ended semistructured interview guide. Three themes were identified: event, fallout, and moving-on. These themes provided the organizing structure for exploring the journey to recovery. This journey, as disclosed by the seriously injured, does not necessarily correspond with the views of most trauma clinicians. Traumatic events create a line of demarcation, separating lives into before and after. The event becomes the starting point of a journey to resume one’s life. The event itself is more than the trauma; it is the perceptual and contextual experience that needs to be incorporated into a person’s essence. Fallout from the injury is multifaceted and includes physical, psychological, social, and spiritual dimensions. Moving-on in this journey is nonlinear as survivors recognize their lives are forever different. The survivors’ accounts suggest that nurses should carefully consider the question, ‘What is successful recovery?

Verbal De-escalation of the Agitated Patient: Consensus Statement of the American Association for Emergency Psychiatry Project BETA De-escalation Workgroup

Agitation is an acute behavioral emergency requiring immediate intervention. Traditional methods of treating agitated patients, ie, routine restraints and involuntary medication, have been replaced with a much greater emphasis on a noncoercive approach. Experienced practitioners have found that if such interventions are undertaken with genuine commitment, successful outcomes can occur far more often than previously thought possible. In the new paradigm, a 3-step approach is used. First, the patient is verbally engaged; then a collaborative relationship is established; and, finally, the patient is verbally de-escalated out of the agitated state. Verbal de-escalation is usually the key to engaging the patient and helping him become an active partner in his evaluation and treatment; although, we also recognize that in some cases nonverbal approaches, such as voluntary medication and environment planning, are also important. When working with an agitated patient, there are 4 main objectives: (1) ensure the safety of the patient, staff, and others in the area; (2) help the patient manage his emotions and distress and maintain or regain control of his behavior; (3) avoid the use of restraint when at all possible; and (4) avoid coercive interventions that escalate agitation. The authors detail the proper foundations for appropriate training for de-escalation and provide intervention guidelines, using the “10 domains of de-escalation.

An Alpha-Catulin Homologue Controls Neuromuscular Function through Localization of the Dystrophin Complex and BK Channels in Caenorhabditis elegans

The large conductance, voltage- and calcium-dependent potassium (BK) channel serves as a major negative feedback regulator of calcium-mediated physiological processes and has been implicated in muscle dysfunction and neurological disorders. In addition to membrane depolarization, activation of the BK channel requires a rise in cytosolic calcium. Localization of the BK channel near calcium channels is therefore critical for its function. In a genetic screen designed to isolate novel regulators of the Caenorhabditis elegans BK channel, SLO-1, we identified ctn-1, which encodes an α-catulin homologue with homology to the cytoskeletal proteins α-catenin and vinculin. ctn-1 mutants resemble slo-1 loss-of-function mutants, as well as mutants with a compromised dystrophin complex. We determined that CTN-1 uses two distinct mechanisms to localize SLO-1 in muscles and neurons. In muscles, CTN-1 utilizes the dystrophin complex to localize SLO-1 channels near L-type calcium channels. In neurons, CTN-1 is involved in localizing SLO-1 to a specific domain independent of the dystrophin complex. Our results demonstrate that CTN-1 ensures the localization of SLO-1 within calcium nanodomains, thereby playing a crucial role in muscles and neurons

Military veteran mortality following a survived suicide attempt

<p>Abstract</p> <p>Background</p> <p>Suicide is a global public health problem. Recently in the U.S., much attention has been given to preventing suicide and other premature mortality in veterans returning from Iraq and Afghanistan. A strong predictor of suicide is a past suicide attempt, and suicide attempters have multiple physical and mental comorbidities that put them at risk for additional causes of death. We examined mortality among U.S. military veterans after hospitalization for attempted suicide.</p> <p>Methods</p> <p>A retrospective cohort study was conducted with all military veterans receiving inpatient treatment during 1993-1998 at United States Veterans Affairs (VA) medical facilities following a suicide attempt. Deaths occurring during 1993-2002, the most recent available year at the time, were identified through VA Beneficiary and Records Locator System data and National Death Index data. Mortality data for the general U.S. adult population were also obtained from the National Center for Health Statistics. Comparisons within the veteran cohort, between genders, and against the U.S. population were conducted with descriptive statistics and standardized mortality ratios. The actuarial method was used estimate the proportion of veterans in the cohort we expect would have survived through 2002 had they experienced the same rate of death that occurred over the study period in the U.S. population having the age and sex characteristics.</p> <p>Results</p> <p>During 1993-1998, 10,163 veterans were treated and discharged at a VA medical center after a suicide attempt (mean age = 44 years; 91% male). There was a high prevalence of diagnosed alcohol disorder or abuse (31.8%), drug dependence or abuse (21.8%), psychoses (21.2%), depression (18.5%), and hypertension (14.2%). A total of 1,836 (18.1%) veterans died during follow up (2,941.4/100,000 person years). The cumulative survival probability after 10 years was 78.0% (95% CI = 72.9, 83.1). Hence the 10-year cumulative mortality risk was 22.0%, which was 3.0 times greater than expected. The leading causes overall were heart disease (20.2%), suicide (13.1%), and unintentional injury (12.7%). Whereas suicide was the ninth leading cause of death in the U.S. population overall (1.8%) during the study period, suicide was the leading and second leading cause among women (25.0%) and men (12.7%) in the cohort, respectively.</p> <p>Conclusions</p> <p>Veterans who have attempted suicide face elevated risks of all-cause mortality with suicide being prominent. This represents an important population for prevention activities.</p

Gardnerella subgroup dominant microbiomes are associated with divergent cervicovaginal immune responses in a longitudinal cohort of Kenyan women

Most cervicovaginal microbiome-immunology studies to date have relied on 16S rDNA microbial profiling which does not resolve the molecular subgroups of Gardnerella, believed to be central to the pathogenesis of bacterial vaginosis (BV) and subsequent risk of HIV acquisition. Here we used the cpn60 universal target which in addition to other microbial taxa, resolves four Gardnerella subgroups, for cervicovaginal microbial profiling in a longitudinal cohort of Kenyan women to examine associations with cellular and soluble markers of inflammation and HIV susceptibility. Participants (N = 41) were sampled, contributing 362 samples for microbiome analysis. All non-Lactobacillus dominant microbial communities were associated with high pro-inflammatory cytokine levels. Divergent associations were observed among different Gardnerella subgroup dominated communities with respect to the chemokine IP-10. Specifically, Gardnerella subgroup A dominant and polymicrobial communities were associated with reduced concentrations of IP-10 in adjusted linear mixed models (p&lt;0.0001), compared to microbial communities dominated by Lactobacillus (non-iners) species. However, these associations did not translate to significant differences in the proportion or absolute number of CCR5, HLA-DR and CD38 expressed on cervical CD4+ T- cells. These findings suggest that some associations between Gardnerella subgroup dominant microbiomes and mucosal immunity differ and are relevant for the study of BV-pathogenesis and understanding the mechanisms of BV-associated HIV risk
