Traumatic brain injury and co-occurring problems in prison populations: a systematic review.

Background: A growing body of epidemiological research suggests high rates of traumatic brain injury (TBI) in prisoners. The aim of this review is to systematically explore the literature surrounding the rates of TBI and their co-occurrences in a prison population.
Methods: Six electronic databases were systematically searched for articles published between 1980 and 2014. Studies were screened for inclusion based on predetermined criteria by two researchers who independently performed data extraction. Study quality was appraised based on a modified quality assessment tool.
Results: Twenty six studies were included in this review. Quality assessment ranged from 20% (poor) to 80% (good) with an overall average of 60%. Twenty four papers included TBI prevalence rates, which ranged from 5.69%-88%. Seventeen studies explored co-occurring factors including rates of aggression (n=7), substance abuse (n=9), anxiety and depression (n=5), neurocognitive deficits (n=4), and psychiatric conditions (n=3).
Conclusions: The high degree of variation in TBI rates may be attributed to the inconsistent way in which TBI was measured with only seven studies using valid and reliable screening tools. Additionally, gaps in the literature surrounding personality outcomes in prisoners with TBI, female prisoners with TBI, and qualitative outcomes were found.

Prevalence and Diagnostic Approach to Sleep Apnea in Hemodialysis Patients: A Population Study.

BACKGROUND: Previous observations found a high prevalence of obstructive sleep apnea (OSA) in the hemodialysis population, but the best diagnostic approach remains undefined. We assessed OSA prevalence and performance of available screening tools to propose a specific diagnostic algorithm. METHODS: 104 patients from 6 Swiss hemodialysis centers underwent polygraphy and completed 3 OSA screening scores: STOP-BANG, Berlin's Questionnaire, and Adjusted Neck Circumference. The OSA predictors were identified on a derivation population and used to develop the diagnostic algorithm, which was validated on an independent population. RESULTS: We found 56% OSA prevalence (AHI ≥ 15/h), which was largely underdiagnosed. Screening scores showed poor performance for OSA screening (ROC areas 0.538 [SE 0.093] to 0.655 [SE 0.083]). Age, neck circumference, and time on renal replacement therapy were the best predictors of OSA and were used to develop a screening algorithm, with higher discriminatory performance than classical screening tools (ROC area 0.831 [0.066]). CONCLUSIONS: Our study confirms the high OSA prevalence and highlights the low diagnosis rate of this treatable cardiovascular risk factor in the hemodialysis population. Considering the poor performance of OSA screening tools, we propose and validate a specific algorithm to identify hemodialysis patients at risk for OSA for whom further sleep investigations should be considered.

The relationship between stem-form, stand-closure and site -conditions : the influence of environmental conditions on tree allometry and forest structure in west-central Alberta

Changes in the configuration of a tree stern result insignificant differences in its total volume and in the proportion of that volume that is merchantable timber. Tree allometry, as represented by stem-fo~, is the result of the vertical force of gravity and the horizontal force of wind. The effect of wind force is demonstrated in the relationship between stem-form, standclosure and site-conditions. An increase in wind force on the individual tree due to a decrease in stand density should produce a more tapered tree. The density of the stand is determined by the conditions that the trees are growing under. The ability of the tree to respond to increased wind force may also be a function of these conditions . This stem-form/stand-closure/site-conditions relationship was examined using a pre-existing database from westcentral Alberta. This database consisted of environmental, vegetation, soils and timber data covering a wide range of sites. There were 653 sample trees with 82 variables that formed the basis of the analysis. There were eight tree species consisting of Pinus contorta, Picea mariana, Picea engelmannii x glauca, Abies lasiocarpa, Larix laricina, Populus tremuloides, Betula papyrifera and Populus balsamifera plus a comprehensive all-species data set. As the actual conformation of the stern is very individual, stem-fo~was represented by the diameter at breast height to total height r~tio. The four stand-closure variables, crown closure, total basal area, total volume and total number of stems were reduced to total basal area and total number of stems utilizing a bivariate correlation matrix by species. Site-conditions were subdivided into macro, meso and micro variables and reduced in number 3 using cross-tabulations, bivariate correlation and principal components analysis as screening tools. The stem-fo~/stand-closure relationship was examined using bivariate correlation coefficients for stem-fo~ with total number of stems and stem-fo~ with total basal area. The stem-fo~/site-conditions and the stand-closure/site- conditions relationships were examined using multiple correlation coefficients. The stem-form/stand-closure/site-conditions relationship was examined using multiple correlation coefficients in separate analyses for both total number of stems and total basal area. An increase in stand-closure produced a decrease in stem-form for both total number of stems and total basal area for most species. There was a significant relationship between stem-form and site-conditions and between stand-closure and site-conditions for both total number of stems and total basal area for most species. There was a significant relationship between the stemform and site-conditions, including the stand-closure, for most species; total number of stems was involved independently of the site-conditions in the prediction of stem-form and total basal area was not. Larix laricina and Betula papyrifera were the exceptions to the trends observed with most species. The influence of both stand-closure (total number of stems in particular) and site-conditions (elevation in particular) suggest that forest management practices should include these- ecological parameters in determining appropriate restocking levels.

Dépistage du décrochage scolaire à l’aide d’informations administratives ou auto-rapportées

Les adolescents qui décrochent de l’école secondaire arrivent difficilement à s’intégrer dans une économie axée sur le savoir et éprouvent plusieurs problèmes d’ajustement à l’adolescence et à l’âge adulte. Pour prévenir le décrochage scolaire, une étape cruciale consiste à dépister efficacement les élèves les plus à risque. Deux formes de dépistage axées sur des données peuvent être utilisées en milieu scolaire: une forme utilisant des informations auto-rapportées par les élèves à partir de questionnaires, et une autre fondée sur des informations administratives consignées au dossier des élèves. Toutefois, à notre connaissance, l’efficacité de ces différentes modalités n’a jamais été comparée directement. De plus, il est possible que l’efficacité relative de ces outils de dépistage soit différente selon le sexe de l’élève. Cette étude vise à comparer différents outils de dépistage pour prédire le décrochage scolaire, en tenant compte de l’effet modérateur du sexe. Les outils utilisés seront a) un questionnaire auto-rapporté validé (Archambault et Janosz, 2009) et b) un outil conçu à l’aide de données administratives, créé par une commission scolaire du Québec. La comparaison de ces outils est effectuée en termes de qualités psychométriques et d’aspect pratique pour le milieu scolaire. Pour ce faire, un échantillon de 1557 élèves (50% de garçons), âgé entre 14 et 18 ans est utilisé. Les résultats indiquent que l’indice administratif possède une capacité discriminante adéquate, mais inférieure à celle de l’indice auto-rapportée, jugée excellente. L’effet modérateur du sexe n’a pas été confirmé. Les avantages et inconvénients respectifs de ces deux modes de dépistage sont discutés.

Perfil neuropsicológico de personas adultas con VIH/SIDA

Los déficit neurológicos en el virus de inmunodeficiencia humana VIH, específicamente las alteraciones en el funcionamiento cognitivo, han estado presentes desde el inicio de su propagación y han sido una de las principales manifestaciones a lo largo de todas las etapas del virus. No obstante, gracias a los avances de la terapia antirretroviral se ha dado un aumento de la expectativa de vida de los pacientes, dándose de la misma manera un incremento en los déficits anteriormente mencionados. El objetivo del presente estudio es describir el perfil neuropsicológico de los pacientes con VIH y establecer si existen relaciones entre las funciones que se encuentren deterioradas, el tiempo de diagnóstico y la terapia antiretroviral. Para esto se llevo a cabo un estudio descriptivo de tipo exploratorio con el fin de medir las características de las funciones neuropsicológicas en un grupo de 24 pacientes pertenecientes al programa especial B24 del Hospital Universitario Mayor y Hospital de Barrios Unidos MÉDERI en Bogotá, Colombia. Para esto, se utilizó un protocolo de pruebas neuropsicológicas: Mini Mental StateExamination (MMSE), WAIS-III (sub-pruebas dígitos, letras y números, aritmética y semejanzas), Curva de aprendizaje auditivo verbal de Rey (RAVLT), WMS-III (sub-pruebas de recobro de historias y Localización), TMT A y B, Set Test de Isaacs, Figura Compleja de Rey y Test de Stroop. Dentro de los resultados se encontró que la medida de edad fue de 50 con un total de 19 hombres y 5 mujeres. Las funciones con mayor predominio de deterioro fueron la atención sostenida y alternante, la memoria declarativa, las funciones ejecutivas (específicamente en el control inhibitorio) y la velocidad de procesamiento, los pacientes presentan un rango de deterioro cognitivo leve (GDS 3). Se concluyó que el perfil de deterioro es mixto y que es necesario ampliar la muestra para obtener resultados más precisos en cuanto a las diferencias de acuerdo al tiempo de diagnóstico y la terapia antiretroviral.

Caracterización del perfil nutricional de pacientes pediátricos hospitalizados en la Clínica Infantil Colsubsidio

Introducción: La desnutrición intrahospitalaria es variable en los estudios publicados. Tiene impacto en el curso tórpido de la enfermedad, en la prolongación de la estancia hospitalaria y en los altos costos subsecuentes. No existen estudios realizados en Colombia en relación al estado nutricional del paciente pediátrico hospitalizado. Por este motivo se decidió caracterizar el perfil nutricional de pacientes pediátricos hospitalizados en la Clínica Infantil Colsubsidio Materiales y métodos: Se desarrolló un estudio transversal en pacientes pediátricos hospitalizados en un periodo entre Junio 2014 – Marzo 2015. Se realizó descripción de las variables y análisis univariado. Resultados: Se analizaron 320 pacientes: 50% niños y 50% niñas. Edad promedio: 4.6 años, predominio del grupo de los lactantes. Media de estancia hospitalaria: 4,6 días. Baja ingesta, ayuno, dolor de moderada intensidad y factor de estrés grado I fueron las variables más frecuentemente relacionadas con desnutrición. Al ingreso a hospitalización el 57.5 % se encontraron eutróficos, el 17.19% con desnutrición crónica, el 8.44% con desnutrición aguda y el 16.88% con aumento anormal de peso. Al egreso, los eutróficos disminuyeron a 56.25 %, la desnutrición crónica y el aumento anormal de peso se mantuvieron igual y la desnutrición aguda aumento al 10%. Conclusión: Los hallazgos de este estudio están en concordancia con los hallazgos descritos en la literatura. El mayor compromiso nutricional se asoció a patologías respiratorias y gastrointestinales y a mayor estancia hospitalaria.

Knowledge and skills of professional carers working with older people with depression

Objectives: The current study was designed to evaluate the knowledge, skills and self-efficacy of care providers from the perspective of professionals working in the aged-care industry.

Method: Participants were 21 professional carers, 10 General Practitioners and 7 aged-care managers. Focus groups, which involved the completion of a semi-structured interview related to knowledge, recognition, confidence, referral procedures and use of screening tools for the detection of depression, were conducted.

Results: The results showed that all groups of respondents recognised significant gap in the knowledge and awareness of depression among professional care staff working with older people in both the community and residential care-settings. Skills in the detection and monitoring of depression and the self-efficacy of these care staff were also seen to be a problem.

Discussion: The implications of these findings in terms of training programmes for professional carers working in the aged health care sector are discussed.

A literature review of the application of the geriatric depression scale, depression anxiety stress scales and post-traumatic stress disorder checklist to community nursing cohorts

Aims and objectives. To explore through literature review the appropriateness of three common tools for use by community nurses to screen war veteran and war widow(er) clients for depression, anxiety and post-traumatic stress disorder.

Background. War veterans and, to a lesser extent, war widow(er)s, are prone to mental health challenges, especially depression, anxiety and post-traumatic stress disorder. Community nurses do not accurately identify such people with depression and related disorders although they are well positioned to do so. The use of valid and reliable self-report tools is one method of improving nurses' identification of people with actual or potential mental health difficulties for referral to a general practitioner or mental health practitioner for diagnostic assessment and treatment. The Geriatric Depression Scale, Depression Anxiety Stress Scales and Post-traumatic Stress Disorder Checklist are frequently recommended for mental health screening but the appropriateness of using the tools for screening war veteran and war widow(er) community nursing clients who are often aged and have functional impairment, is unknown.

Design. Systematic review.

Conclusions. Current literature informs that the Geriatric Depression Scale accurately predicts a diagnosis of depression in community nursing cohorts. The three Depression Anxiety Stress Scales subscales of depression, anxiety and stress are valid; however, no studies were identified that compared the performance of the Depression Anxiety Stress Scales in predicting diagnoses of depression or anxiety. The Post-traumatic Stress Disorder Checklist predicts post-traumatic stress disorder in community cohorts although no studies meeting the selection criteria included male participants.

Relevance to clinical practice. This review provides recommendations for the use of the Geriatric Depression Scale, Depression Anxiety Stress Scales and The Post-traumatic Stress Disorder Checklist based on examination of the published evidence for the application of these screening tools in samples approximated to community nursing cohorts. Findings and recommendations would guide community nurses, managers and health planners in the selection of mental health screening tools to promote holistic community nursing care.

Recurrent events counted in evaluations of predictive accuracy

Objectives: To describe an alternate approach for the calculation of sensitivity and specificity when analyzing the accuracy of screening tools, which can be used when standard calculations may be inappropriate. Sensitivity^ER (ER denoting event rate) is the number of events correctly predicted, divided by the total number of events. Specificity^ER is the amount of time that study participants are predicted to be event negative, divided by the total amount of participant observed time. Variance estimates for these statistics are constructed by bootstrap resampling, taking into account event dependence.

Methods: Standard and alternate approaches for calculating sensitivity and specificity were applied to hospital falls risk screening tool data. In this application, the outcome of interest was a recurrent event, there were multiple applications of the screening tool, delays in screening tool  completion, and patients' follow-up durations were unequal.

Results: Application of sensitivity^ER and specificity^ER to this data not only provided a clearer description of the screening tool's overall accuracy, but also allowed examination of accuracy over time, accuracy in predicting specific event numbers, and evaluation of the added value that screening tool reapplications may have.

Conclusion: Sensitivity^ER and specificity^ER provide a valuable approach to screening tool evaluation in the clinical setting.

Women's views and outcomes of an educational intervention designed to enhance psychosocial support for women during pregnancy

Background: Identification of psychosocial issues in pregnant women by screening is difficult because of the lack of accuracy of screening tools, women's reluctance to disclose sensitive issues, and health care practitioner's reluctance to ask. This paper evaluates if a health professional education program, a new (ANEW) approach, improves pregnant women's ratings of care and practitioner's listening skills and comfort to disclose psychosocial issues.

Methods: Midwives and doctors from Mercy Hospital for Women, Melbourne, Australia, were trained from August to December 2002. English-speaking women (< 20 wks' gestation) were recruited at their first visit and mailed a survey at 30 weeks (early 2002) before and after (2003) the ANEW educational intervention. Follow-up was by postal reminder at 2 weeks and telephone reminder 2 weeks later.

Results: Twenty-one midwives and 5 doctors were trained. Of the eligible women, 78.2 percent (584/747) participated in a pre-ANEW survey and 73.3 percent (481/657) in a post-ANEW survey. After ANEW, women were more likely to report that midwives asked questions that helped them to talk about psychosocial problems (OR 1.45, CI 1.09–1.98) and that they would feel comfortable to discuss a range of psychosocial issues if they were experiencing them (coping after birth for midwives [OR 1.51, CI 1.10–2.08] and feeling depressed [OR 1.49, 1.16–1.93]; and concerns relating to sex [OR 1.35, CI 1.03–1.77] or their relationships [OR 1.36, CI 1.00–1.85] for doctors).

Conclusions: The ANEW program evaluation suggests trends of better communication by health professionals for pregnant women and should be evaluated using rigorous methods in other settings.

An evaluation of a national program to implement the cornell scale for depression in dementia into routine practice in aged care facilities

Background: Screening tools have been recommended for use in aged care to improve the detection and treatment of depression. This study aimed to evaluate the impact of a program for the routine implementation of the Cornell Scale for Depression in Dementia in Australian facilities, to determine whether use of the instrument by nurses led to further monitoring of depressive symptoms, medical referral, and changes in treatments prescribed for depression.
Methods: A file review was completed for 412 participants out of a total of 867 older people (47.5%) who resided in ten aged care facilities. The review examined Cornell Scale assessment data, medication charts, medical history, nursing progress notes, and resident care plans. Nursing staff who administered the Cornell Scale to each participant were also interviewed, and ten facilitymanagers took part in an interview to determine barriers to the effective implementation of the instrument.
Results: The Cornell Scale had been administered to 46.8% of the sample in the previous 12 months, with 25% of these participants scoring 9–13 and 27% scoring 14 and above. Less than one third of the residents with high scores were monitored by the staff following the assessment. Only 18% of residents with high scores were referred for further assessment of depression, while 10% received a treatment change.
Conclusions: The absence of a protocol for responding to high Cornell Scale scores limited the potential of this program to result in widespread improved treatment of depressed older people. The use of the Cornell Scale by aged care nurses with limited training raised concern.

Recruitment into diabetes prevention programs : what is the impact of errors in self-reported measures of obesity?

Background
Error in self-reported measures of obesity has been frequently described, but the effect of self-reported error on recruitment into diabetes prevention programs is not well established. The aim of this study was to examine the effect of using self-reported obesity data from the Finnish diabetes risk score (FINDRISC) on recruitment into the Greater Green Triangle Diabetes Prevention Project (GGT DPP).

Methods
The GGT DPP was a structured group-based lifestyle modification program delivered in primary health care settings in South-Eastern Australia. Between 2004–05, 850 FINDRISC forms were collected during recruitment for the GGT DPP. Eligible individuals, at moderate to high risk of developing diabetes, were invited to undertake baseline tests, including anthropometric measurements performed by specially trained nurses. In addition to errors in calculating total risk scores, accuracy of self-reported data (height, weight, waist circumference (WC) and Body Mass Index (BMI)) from FINDRISCs was compared with baseline data, with impact on participation eligibility presented.

Results
Overall, calculation errors impacted on eligibility in 18 cases (2.1%). Of n = 279 GGT DPP participants with measured data, errors (total score calculation, BMI or WC) in self-report were found in n = 90 (32.3%). These errors were equally likely to result in under- or over-reported risk. Under-reporting was more common in those reporting lower risk scores (Spearman-rho = −0.226, p-value < 0.001). However, underestimation resulted in only 6% of individuals at high risk of diabetes being incorrectly categorised as moderate or low risk of diabetes.

Conclusions
Overall FINDRISC was found to be an effective tool to screen and recruit participants at moderate to high risk of diabetes, accurately categorising levels of overweight and obesity using self-report data. The results could be generalisable to other diabetes prevention programs using screening tools which include self-reported levels of obesity.

Psychiatric disorders and unmet needs in Australian police cells

To determine the prevalence of current psychiatric disorders and unmet needs in a sample of police cell detainees in Victoria. A cross-sectional descriptive study was conducted, including data linkage with the Victoria Police database and the Victorian Psychiatric Case Register. In Melbourne, Australia, 150 detainees were recruited from two busy metropolitan police stations. Outcome measures included estimated rates of psychiatric disorders, using the Structured Clinical Interview for DSM-IV-TR, and individual needs, using the Camberwell Assessment of Need – Forensic Version. One quarter (n = 32, 25.4%) of detainees had a prior admission to a psychiatric hospital, and three quarters met current criteria for a diagnosable mental disorder. The most common disorders were substance dependence (n = 81, 54%) and mood disorders (n = 60, 40%). A third met diagnostic criteria for both a mental illness and a substance use disorder. The odds of being classified with mood (OR = 10.1), anxiety (OR = 2.2), psychotic (OR = 15.4) and substance use disorders (OR = 26.3) were all significantly higher in the current sample as compared with the general population. Detainees with a mental illness identified significantly more needs and significantly more unmet needs (e.g. psychological distress) than those who did not rate as having a current mental illness. There remains a pressing need to evaluate standardized screening tools for mental illnesses in police cells to provide timely access to assessment and treatment services. The need for functional interagency collaborations are highlighted and discussed.

Prioritizing climate change adaptation options for iconic marine species

© 2015, Springer Science+Business Media Dordrecht. Adaptation options in response to climate impact scenarios for marine mammals and seabirds were developed based on the IPCC vulnerability framework. Under this framework, vulnerability to the physical effects of climate change can be reduced by adaptation options that reduce exposure of individuals, reduce the sensitivity of individuals, and increase the adaptive capacity of individual/species to cope with climate change. We evaluated options in each vulnerability category with three screening tools collectively forming an approach we term sequential adaptation prioritization for species. These tools were designed to evaluate (i) technical aspects (cost-benefit-risk, CBR), (ii) institutional barriers, and (iii) potential social acceptability. The CBR tool identified which adaptation options were high cost and low benefit, might be discarded, and which were high benefit and low cost, might be rapidly implemented (depending on risk). Low cost and low benefit options might not be pursued, while those that are high cost, but high benefit deserve further attention. Even with technical merit, adaptation options can fail because of institutional problems with implementation. The second evaluation tool, based on the conceptual framework on barriers to effective climate adaptation, identifies where barriers may exist, and leads to strategies for overcoming them. Finally, adaptation options may not be acceptable to society at large, or resisted by vocal opponents or groups. The social acceptability tool identifies potentially contested options, which may be useful to managers charged with implementing adaptation options. Social acceptability, as scored by experts, differed from acceptability scored by the public, indicating the need to involve the public in assessing this aspect. Scores from each tool for each scenario can be combined to rank the suite of adaptation options. This approach provides useful tools to assist conservation managers in selecting from a wide range of adaptation strategies; the methodology is also applicable to other conservation sectors.
