Avaluació i predicció del risc de reincidencia en agressors sexuals

En el marc de la intervenció penitenciària amb agressors sexuals, té una especial rellevància la predicció de risc del seu comportament futur, atenent les greus repercussions que poden arribar a tenir les reincidències, tant per a les possibles víctimes com des de la perspectiva de l’impacte mediàtic i pànic moral que generen. En el context internacional, gran part de l’esforç investigador en aquesta matèria ha anat adreçat a l’estandardització de protocols per avaluar el risc de reincidència d’aquests subjectes i orientar la presa de decisions envers ells i la seva vida fora del règim penitenciari. Un dels instruments més novedosos per a la predicció del risc d’agressió sexual és el Sexual Violence Risc – 20 (SVR-20) desenvolupat per un equip d’investigadors canadencs. El treball que aquí es presenta s’inscriu en el marc de l’aplicació pràctica d’aquests procediments predictius al nostre país. L’objectiu principal és aplicar l’SVR-20, de manera retrospectiva, a una mostra d’agressors sexuals per avaluar la capacitat predictiva d’aquest instrument i, així, poder anticipar la possible reincidència dels subjectes. Per aconseguir aquest objectiu, la puntuació total del SVR-20 ha estat correlacionada amb la reincidència veritable, considerant el tractament com una variable a tenir en compte. La regressió logística ha estat utilitzada per examinar el calibratge del model. Aquesta anàlisi avalua el grau de correspondència entre les probabilitats predites (de reincidència) i la reincidència esdevinguda. L’SVR-20 prediu correctament el 55% dels no-reincidents i el 16% dels reincidents. Podem afirmar que aquest model prediu molt millor la reincidència que la no-reincidència. A més, la predicció millora quan hi incloem la variable de tractament. Aquest estudi és el primer a Catalunya que avalua la validesa predictiva d’un instrument d’avaluació del risc de violència sexual. Futures recerques haurien de centrar-se a estimar un punt de tall per a l’SVR-20 que permeti classificar els subjectes de risc de reincidència dels subjectes segurs.

Drug Misuse in Dublin, July 1982

In this report for the Medico Social Research Board the author provides an overview of the drug problem in Dublin's inner city. On 12-14 July 1982 the author visited the Sean Mac Dermott street area of the inner city, the Eastern Health Board, Coolmine Community, Jervis Street Drug Advisory and Treatment Centre and the Garda drug squad. From these interviews, the author concludes that Dublin's inner city has a serious problem with drug use, in particular the injecting of heroin. Heroin addicts steal on a regular basis to fund their habit, and frequently inject themselves in public spaces of local authority flat complexes. Despite the best efforts of the support services (Social workers, doctors, Gardai and clergy) there is a high prevalence of injecting heroin use. There has also been abuse of prescription services. Addicts frequently seek opiates from a small number of doctors who are willing to prescribe. Drug education is severely lacking or inappropriate, according to the author, and the Garda drug squad is severely over stretched. While cannabis use is said to be prevalent in Dublin's two universities, drug use has been most problematic in the deprived parts of the city. The author presents the drug epidemic, which has developed over the last two years, in moral terms, and wonders if Christian society, in particular the Catholic Church, and the health authorities can do anything to stop the crisis from worsening. Recommendations include; conducting epidemiological surveys to determine the true extent of the problem, cross disciplinary co-operation, greater drug awareness through education, and more rehabilitation units.This resource was contributed by The National Documentation Centre on Drug Use.

ASIST training helping to tackle suicide

Work to help communities prevent suicide has taken a further step forward with over 50 ASIST Trainers from across Northern Ireland completing the new ASIST 11 upgrader trainer course.The Applied Suicide Intervention Skills Training (ASIST) enables people in a position of trust to recognise risk and learn how to intervene to prevent the immediate risk of suicide.The Public Health Agency (PHA) funded the upgrading training as part of their ongoing commitment to supporting quality training for a range of individuals, communities and organisations.Madeline Heaney, the PHA's strategic lead for Suicide Prevention, explained: "This programme enables people who have been trained to become more willing, ready and able to help those at risk of suicide, which can be vital in a crisis situation.�"We want to empower people who are in position of responsibility and care to know what to do if they find themselves in a situation where someone is at risk of taking their own lives."�ASIST has been delivered in Northern Ireland since 2003 and the course is designed for all caregivers or any person in a position of trust, making it useful for a range of people. The training is suitable for mental health professionals, nurses, doctors, pharmacists, teachers, counsellors, youth workers, police and prison staff, school support staff, clergy, community volunteers and the general public.This most recent training, which ASIST Trainers must complete, builds on previous editions and offers advances that help meet current challenges and provides new opportunities in helping to reduce suicides within communities.The intensive Trainer Upgrade was held in Derry/ Londonderry.More information on looking after your mental health and the support which is available across Northern Ireland can be found at www.mindingyourhead.info��You can also talk to your GP for advice.If you or someone you know is in distress or despair, call Lifeline on 0808 808 8000. This is a confidential service, where trained counsellors will listen and help immediately on the phone and follow up with other support if necessary. The helpline is available 24 hours a day, seven days a week. You can also access the Lifeline website at www.lifelinehelpline.info

(.)VO(2) and EMG activity kinetics during moderate and severe constant work rate exercise in trained cyclists.

The purpose of this study was to compare O(2) uptake ((.)VO(2)) and muscle electromyography activity kinetics during moderate and severe exercise to test the hypothesis of progressive recruitment of fast-twitch fibers in the explanation of the VO(2) slow component. After an incremental test to exhaustion, 7 trained cyclists (mean +/- SD, 61.4 +/- 4.2 ml x min(-1) x kg(- 1)) performed several square-wave transitions for 6 min at moderate and severe intensities on a bicycle ergometer. The (.)VO(2) response and the electrical activity (i.e., median power frequency, MDF) of the quadriceps vastus lateralis and vastus medialis of both lower limbs were measured continuously during exercise. After 2 to 3 min of exercise onset, MDF values increased similarly during moderate and severe exercise for almost all muscles whereas a (.)VO(2) slow component occurred during severe exercise. There was no relationship between the increase of MDF values and the magnitude of the (.)VO(2) slow component during the severe exercise. These results suggest that the origin of the slow component may not be due to the progressive recruitment of fast-twitch fibers.

Dynamic responses of oxygen uptake at the onset and end of moderate and heavy exercise in trained subjects.

Inconsistencies about dynamic asymmetry between the on- and off-transient responses in VO2 are found in the literature. Therefore the purpose of this study was to examine VO2 on- and off-transients during moderate- and heavy-intensity cycling exercise in trained subjects. Ten men underwent an initial incremental test for the estimation of ventilatory threshold (VT) and, on different days, two bouts of square-wave exercise at moderate (<VT) and heavy (>VT) intensities. VO2 kinetics in exercise and recovery were better described by a single exponential model (<VT), or by a double exponential with two time delays (>VT). For moderate exercise, we found a symmetry of VO2 kinetics between the on- and off-transients (i.e., fundamental component), consistent with a system manifesting linear control dynamics. For heavy exercise, a slow component superimposed on the fundamental phase was expressed in both the exercise and recovery, with similar parameter estimates. But the on-transient values of the time constant were appreciably faster than the associated off-transient, and independent of the work rate imposed (<VT and >VT). Our results do not support a dynamically linear system model of VO2 during cycling exercise in the heavy-intensity domain.

Open access press vs traditional university presses on Amazon

This study is a comparison AU Press with three other traditional (non-open access) Canadian university presses. The analysis is based on actual physical book sales on Amazon.com and Amazon.ca. Statistical methods include the sampling of the sales ranking of randomly selected books from each press. Results suggest that there is no significant difference in the ranking of printed books sold by AU Press in comparison with traditional university presses. However, AU Press, can demonstrate a significantly larger readership for its books as evidenced by thousands of downloads of the open electronic versions.

Optimization of treatment with interferon beta in multiple sclerosis. Usefulness of automatic system application criteria

Background. A software based tool has been developed (Optem) to allow automatize the recommendations of the Canadian Multiple Sclerosis Working Group for optimizing MS treatment in order to avoid subjective interpretation. METHODS: Treatment Optimization Recommendations (TORs) were applied to our database of patients treated with IFN beta1a IM. Patient data were assessed during year 1 for disease activity, and patients were assigned to 2 groups according to TOR: "change treatment" (CH) and "no change treatment" (NCH). These assessments were then compared to observed clinical outcomes for disease activity over the following years. RESULTS: We have data on 55 patients. The "change treatment" status was assigned to 22 patients, and "no change treatment" to 33 patients. The estimated sensitivity and specificity according to last visit status were 73.9% and 84.4%. During the following years, the Relapse Rate was always higher in the "change treatment" group than in the "no change treatment" group (5 y; CH: 0.7, NCH: 0.07; p < 0.001, 12 m - last visit; CH: 0.536, NCH: 0.34). We obtained the same results with the EDSS (4 y; CH: 3.53, NCH: 2.55, annual progression rate in 12 m - last visit; CH: 0.29, NCH: 0.13). CONCLUSION: Applying TOR at the first year of therapy allowed accurate prediction of continued disease activity in relapses and disability progression.
