Conditional release: A less restrictive alternative to hospitalization?

Objective: This study examined conditional release - that is, involuntary outpatient commitment orders upon release from hospitalization - as a least restrictive alternative to psychiatric hospitalization in Victoria, Australia. Methods: Records were obtained from the Victorian Psychiatric Case Register for patients who experienced psychiatric hospitalization: between 1990 and 2000 a total of 8,879 patients were given conditional release and 16,094 were not. Results: Compared with the group that was hospitalized but did not receive a conditional release, the group that received a conditional release was more likely to have more prior hospitalizations of greater than average duration. Patients with schizophrenia were more likely to be given conditional release. Patients given conditional release experienced a care pattern involving briefer inpatient episodes (8.3 fewer days per episode), more inpatient days, and longer duration of restrictive care - that is, combined inpatient and conditional release periods (5.1 more days per month in care). Conclusions: For patients at risk of long-term hospitalization, conditional release may help to shorten inpatient episodes by providing a least restrictive alternative to continued hospitalization. However, patients who were given conditional release doubled the amount of days they spent under restrictive care, compared with the amount of time they previously spent in the hospital before entering a period of combined inpatient and conditional release commitment. Additional oversight may have led to more frequent hospitalization. This consequence raises new questions regarding the possible benefits of such extended oversight and new challenges for release planning using conditional release as a least restrictive method of care.

Effect of conditional release from hospitalization on mortality risk

Objectives: This study considered the protective value provided by conditional release. It assessed the contribution of conditional release to mortality risk among patients with mental disorders severe enough to require psychiatric hospitalization during a mental health treatment span of 13.5 years in Victoria, Australia. Methods: Death records were obtained from the Australian National Death Index for a sample of 24,973 Victorian Psychiatric Case Register patients with a history of psychiatric hospitalizations: 8,879 had experienced at least one conditional release during community care intervals and 16,094 had not. Risk of death was assessed with standardized mortality ratios of the general population of Victoria. Relative risk of death among patients with and without past experience of conditional release was computed with risk and odds ratios. The contribution of conditional release to mortality, taking into account use of community care services, age, gender, inpatient experience, and diagnosis, as well as other controls, was assessed with logistic regression. Results: Patients who had been hospitalized showed higher mortality risk than the general population. Sixteen percent ( 4,034) died. Patients exposed to conditional release, however, had a 14 percent reduction in probability of noninjury-related death and a 24 percent reduction per day on orders in the probability of death from injury compared with those not offered such oversight throughout their mental health treatment, all other factors taken into account. Conclusions: Conditional release can offer protective oversight for those considered dangerous to self or others and appears to reduce mortality risk among those with disorders severe enough to require psychiatric hospitalization.

Factors in the selection of patients for conditional release from their first psychiatric hospitalization

Objective: This study examined a sample of patients in Victoria, Australia, to identify factors in selection for conditional release from an initial hospitalization that occurred within 30 days of entry into the mental health system. Methods: Data were from the Victorian Psychiatric Case Register. All patients first hospitalized and conditionally released between 1990 and 2000 were identified (N = 8,879), and three comparison groups were created. Two groups were hospitalized within 30 days of entering the system: those who were given conditional release and those who were not. A third group was conditionally released from a hospitalization that occurred after or extended beyond 30 days after system entry. Logistic regression identified characteristics that distinguished the first group. Ordinary least-squares regression was used to evaluate the contribution of conditional release early in treatment to reducing inpatient episodes, inpatient days, days per episode, and inpatient days per 30 days in the system. Results: Conditional release early in treatment was used for 11 percent of the sample, or more than a third of those who were eligible for this intervention. Factors significantly associated with selection for early conditional release were those related to a better prognosis ( initial hospitalization at a later age and having greater than an 11th grade education), a lower likelihood of a diagnosis of dementia or schizophrenia, involuntary status at first inpatient admission, and greater community involvement ( being employed and being married). When the analyses controlled for these factors, use of conditional release early in treatment was significantly associated with a reduction in use of subsequent inpatient care.

Avaluació de necessitats i disseny de la intervenció per a la reintegració social dels delinqüents sexuals d’alt risc

Aquest treball recull les necessitats per la reintegració que presenten els delinqüents sexuals a les presons catalanes i com es poden abordar aquestes mitjançant un model que ha donat bons resultats a altres països: Circles of Support and Accountability (CoSA a partir d'ara). L'objectiu és conèixer com funcionen els Cercles de Suport i Responsabilitat i quins són els requisits necessaris per adaptar aquest model als serveis penitenciaris de Catalunya. Amb aquesta finalitat s'ha fet una anàlisi quantitativa dels principals trets de la població penitenciària catalana, s'ha revisat la bibliografia sobre el model CoSA i s'ha fet observació de camp en la seva aplicació al Regne Unit. També s'ha comptat amb les opinions d'experts i professionals de Catalunya i s'han fet entrevistes a una petita mostra de delinqüents sexuals en règim de semillibertat. Tot i que a Catalunya hi ha programes a les presons per potenciar la rehabilitació dels delinqüents sexuals, la investigació destaca l’important paper del suport social i del manteniment dels canvis del tractament en el medi comunitari com elements clau per la reducció de la reincidència. El model Cercles optimitza l'efecte d'aquests processos i alhora ofereix un model de supervisió que concilia l'objectiu de protecció pública amb la reintegració del delinqüent. De l'estudi de la població penitenciària es conclou que hi ha una part d'interns que es podrien beneficiar d'aquest programa i que el reconeixen com una font important de suport davant les importants dificultats que troben en el procés de retorn a la llibertat. Es proposa un programa CerclesCat adaptat a la realitat del sistema penitenciari català i es descriu el procés d'implementació.

Evaluación de necesidades y diseño de la intervención para la reintegración social de los delincuentes sexuales de alto riesgo

Este trabajo recoge las necesidades para la reintegración que presentan los delincuentes sexuales de las prisiones catalanas y cómo se pueden abordar éstas mediante un modelo que ha dado buenos resultados en otros países: Circles of Support and Accountability (CoSA a partir de ahora). El objetivo es conocer cómo funcionan los Círculos de Apoyo y Responsabilidad y cuáles son los requisitos necesarios para adaptar este modelo a los servicios penitenciarios de Cataluña. Con este fin se ha hecho un análisis cuantitativo de los principales rasgos de la población penitenciaria catalana, se ha revisado la bibliografía sobre el modelo CoSA y se ha hecho observación de campo en su aplicación en el Reino Unido. También se ha contado con las opiniones de expertos y profesionales de Cataluña y se han realizado entrevistas a una pequeña muestra de delincuentes sexuales en régimen de semilibertad. Aunque en Cataluña hay programas en las prisiones para potenciar la rehabilitación de los delincuentes sexuales, la investigación destaca el importante papel del apoyo social y del mantenimiento de los cambios del tratamiento en el medio comunitario como elementos clave para la reducción de la reincidencia. El modelo de Círculos optimiza el efecto de estos procesos, y muestra un modelo de supervisión que concilia el objetivo de protección pública con la reintegración del delincuente. Del estudio de la población penitenciaria se concluye que hay una parte de internos que podrían beneficiarse de este programa y que lo reconocen como una fuente importante de apoyo ante las importantes dificultades que encuentran en el proceso de retorno a la libertad. Se propone un programa CerclesCat adaptado a la realidad del sistema penitenciario catalán y se describe el proceso de implementación.

La llibertat condicional a Catalunya

La recerca analitza quines són les claus actuals de l’ús dela LCa Catalunya. Per fer-ho, primer de tot explica quina és la realitat de les polítiques criminals i d’execució penal practicades a Catalunya i a Espanya i les compara amb altres realitats europees. Els resultats d’aquesta primera part fonamenten la conveniència de fer augmentar de manera significativa la seva aplicació i com aquest augment repercutiria positivament en la millora de les taxes de reincidència, en el desistiment del delicte i en la reinserció social de les persones encarcerades. En la segona part de l’estudi s’analitza el perfil de les persones que arriben a la LC però també de les que no hi arriben, tot i complir algunes de les condicions objectives per fer-ho. De l’estudi d’aquests perfils s’analitzen les similituds i diferències en les característiques dels penats i es fan propostes de millora en la classificació de grau penitenciari i la possibilitat de progressió sense que augmenti el risc teòric de reincidència ni el de recursos a assignar, tot i que sí resulti necessari pensar i fer-ne una redistribució dels actualment existents. La tercera part de l’estudi es dedica a analitzar els obstacles que té l’Administració per poder fer propostes de millora per augmentar la seva implementació. Entre les dificultats analitzades es comenten: el model d’aplicació espanyol sobre la LC, la satisfacció de la responsabilitat civil, els estrangers que es troben en situació administrativa irregular a Espanya, els retards en la concessió dels permisos ordinaris i les progressions de grau i el seguiment i control de la LC. L’estudi ha fet servir metodologies quantitatives i qualitatives simultàniament. La informació obtinguda es triangula i s’assenyalen aquells punts on el consens és més global i aquells punts més controvertits on els resultats no permeten extreure’n conclusions fefaents. En la part quantitativa s’han analitzat utilitzant diferents tècniques estadístiques 3.340 casos que es trobaven l’any 2012 en LC, 3r grau i 2n grau. En la part qualitativa, s’ha fet anàlisi de casos, entrevistes en profunditat, grups focals, tècnica Delphi i recull bibliogràfic i de legislació comparada. La recerca acaba proposant 23 propostes de millora agrupades en 6 blocs d’intervenció.

La libertad condicional en Cataluña

La investigación analiza cuáles son las claves actuales del uso de la libertad condicional (LC) en Cataluña. Para hacerlo, primero explica cuáles son las realidades de las políticas criminales y de ejecución penal practicadas en Cataluña y España y las compara con otras realidades europeas. Los resultados de esta primera parte fundamentan la conveniencia de aumentar de manera significativa su aplicación y cómo este aumento repercutiría positivamente en la mejora de las tasas de reincidencia, en el desistimiento del delito y en la reinserción social de las personas encarceladas. En la segunda parte del estudio se analiza el perfil de las personas que llegan a LC, pero también de las que no llegan, a pesar de cumplir algunas de las condiciones objetivas para hacerlo. Del estudio de estos perfiles se analizan las similitudes y diferencias en las características de los penados y se hacen propuestas de mejora en la clasificación de grado penitenciario y la posibilidad de progresión sin que aumente el riesgo teórico de reincidencia ni el de recursos a asignar, aunque sí hacer una redistribución de los actualmente existentes. La tercera parte del estudio analiza los obstáculos que tiene la Administración para poder hacer propuestas de mejora para aumentar la aplicación de la LC. Entre las dificultades analizadas se comentan: el modelo de aplicación español sobre la LC, la satisfacción de la responsabilidad civil, los extranjeros que se encuentran en situación administrativa irregular en España, los retrasos en la concesión de los permisos ordinarios y las progresiones de grado y el seguimiento y control de la LC. El estudio ha utilizado metodologías cuantitativas y cualitativas simultáneamente. La información obtenida se triangula y se señalan aquellos puntos donde el consenso es más global y aquellos puntos más controvertidos donde los resultados no permiten extraer conclusiones fehacientes. En la parte cuantitativa se han analizado 3.340 casos que se encontraban en 2012 en LC, 3 º grado y 2 º grado utilizando diferentes técnicas estadísticas. En la parte cualitativa, se han hecho análisis de casos, entrevistas en profundidad, grupos focales, técnica Delphi y recopilación bibliográfica y de legislación comparada. La investigación termina proponiendo 23 propuestas de mejora agrupadas en 6 bloques de intervención.

La métrique de la juste peine : une analyse des décisions de justice prises par les acteurs judiciaires et le public

La thèse délaisse l’étude des biais, des erreurs et des influences externes qui modulent les décisions de justice et formule l’hypothèse que les individus, confrontés à un dilemme normatif (quelle serait la juste peine?), manifestent un souci de justice qu’il est pertinent d’analyser en lui-même. Les résultats de cette thèse indiquent qu’une proportion appréciable des choix et des jugements des citoyens et des acteurs judiciaires interrogés témoignent, en raison de leur cohérence interne et de leur modération, d’un souci manifeste de justice. Les données de la thèse s’appuient sur un sondage sentenciel dans lequel on demandait à des répondants du public (n=297), mais aussi à un échantillon d’acteurs judiciaires (n=235), de prendre des décisions de détermination pénale dans trois histoires de cas bien détaillées. La thèse s’intéresse à la détermination de la juste peine, laquelle incorpore trois prises de décision distinctes. Le premier chapitre de la thèse s’attarde à la qualité des échelles individuelles de sévérité des peines qui peuvent être infligées pour sanctionner un délinquant reconnu coupable d’actes criminels. Les résultats indiquent que les citoyens, tous comme les acteurs judiciaires, n’utilisent pas la même métrique pour statuer sur la sévérité des peines, mais que certains d’entre eux, font usage d’une métrique pénale plus cohérente et plus raisonnable que d’autres. Un test décisif pour jauger de la valeur d’une métrique est son aptitude à établir des équivalences pénales entre les peines de prison, de probation, de travaux communautaires et d’amendes. Le deuxième chapitre s’attarde à la qualité des choix sentenciels des citoyens et des acteurs judiciaires. Deux critères sont utilisés pour distinguer les sentences les plus justes : 1) le critère de proportionnalité ou de cohérence interne (les sentences données sont-elles toujours proportionnelles à la gravité de l’infraction commise ?); 2) le critère de modération ou de cohérence externe (la sentence donnée peut-elle rallier le plus grand nombre de points de vue?). Les deux critères sont importants parce qu’ils contribuent tous deux à réduire la marge d’incertitude du dilemme sentenciel. Le troisième chapitre prend acte que toute sentence fera possiblement l’objet d’un aménagement subséquent. Les formes les plus manifestes d’aménagement pénal sont régies par l’octroi d’une libération conditionnelle qui écourte la durée de peine qui sera purgée en prison. Certains acteurs judiciaires choisiront de tenir compte de cette libération anticipée en gonflant leur sentence, alors que d’autres se refuseront à le faire. Le dernier chapitre s’attarde aux raisons qui motivent leurs choix.

Conditional BDNF release under pathological conditions improves Huntington's disease pathology by delaying neuronal dysfunction

Background Brain-Derived Neurotrophic Factor (BDNF) is the main candidate for neuroprotective therapy for Huntington's disease (HD), but its conditional administration is one of its most challenging problems. Results Here we used transgenic mice that over-express BDNF under the control of the Glial Fibrillary Acidic Protein (GFAP) promoter (pGFAP-BDNF mice) to test whether up-regulation and release of BDNF, dependent on astrogliosis, could be protective in HD. Thus, we cross-mated pGFAP-BDNF mice with R6/2 mice to generate a double-mutant mouse with mutant huntingtin protein and with a conditional over-expression of BDNF, only under pathological conditions. In these R6/2:pGFAP-BDNF animals, the decrease in striatal BDNF levels induced by mutant huntingtin was prevented in comparison to R6/2 animals at 12 weeks of age. The recovery of the neurotrophin levels in R6/2:pGFAP-BDNF mice correlated with an improvement in several motor coordination tasks and with a significant delay in anxiety and clasping alterations. Therefore, we next examined a possible improvement in cortico-striatal connectivity in R62:pGFAP-BDNF mice. Interestingly, we found that the over-expression of BDNF prevented the decrease of cortico-striatal presynaptic (VGLUT1) and postsynaptic (PSD-95) markers in the R6/2:pGFAP-BDNF striatum. Electrophysiological studies also showed that basal synaptic transmission and synaptic fatigue both improved in R6/2:pGAP-BDNF mice. Conclusions These results indicate that the conditional administration of BDNF under the GFAP promoter could become a therapeutic strategy for HD due to its positive effects on synaptic plasticity.

In vivo conditional Pax4 overexpression in mature islet β-cells prevents stress-induced hyperglycemia in mice.

OBJECTIVE To establish the role of the transcription factor Pax4 in pancreatic islet expansion and survival in response to physiological stress and its impact on glucose metabolism, we generated transgenic mice conditionally and selectively overexpressing Pax4 or a diabetes-linked mutant variant (Pax4R129 W) in β-cells. RESEARCH DESIGN AND METHODS Glucose homeostasis and β-cell death and proliferation were assessed in Pax4- or Pax4R129 W-overexpressing transgenic animals challenged with or without streptozotocin. Isolated transgenic islets were also exposed to cytokines, and apoptosis was evaluated by DNA fragmentation or cytochrome C release. The expression profiles of proliferation and apoptotic genes and β-cell markers were studied by immunohistochemistry and quantitative RT-PCR. RESULTS Pax4 but not Pax4R129 W protected animals against streptozotocin-induced hyperglycemia and isolated islets from cytokine-mediated β-cell apoptosis. Cytochrome C release was abrogated in Pax4 islets treated with cytokines. Interleukin-1β transcript levels were suppressed in Pax4 islets, whereas they were increased along with NOS2 in Pax4R129 W islets. Bcl-2, Cdk4, and c-myc expression levels were increased in Pax4 islets while MafA, insulin, and GLUT2 transcript levels were suppressed in both animal models. Long-term Pax4 expression promoted proliferation of a Pdx1-positive cell subpopulation while impeding insulin secretion. Suppression of Pax4 rescued this defect with a concomitant increase in pancreatic insulin content. CONCLUSIONS Pax4 protects adult islets from stress-induced apoptosis by suppressing selective nuclear factor-κB target genes while increasing Bcl-2 levels. Furthermore, it promotes dedifferentiation and proliferation of β-cells through MafA repression, with a concomitant increase in Cdk4 and c-myc expression.

Conditional symmetric instability in sting-jet storms

Sting jets are transient mesoscale jets of air that descend from the tip of the cloud head towards the top of the boundary layer in severe extratropical cyclones and can lead to damaging surface wind gusts. This recently identified jet is distinct from the well-documented jets associated with the cold and warm conveyor belts. One mechanism proposed for their development is the release of conditional symmetric instability (CSI). Here the spatial distribution and temporal evolution of several CSI diagnostics in four severe storms are analysed. A sting jet has been identified in three of these storms; for comparison, we also analysed one storm that did not have a sting jet, even though it hadmany of the apparent features of sting-jet storms. The sting-jet storms are distinct from the non-sting-jet storms by having much greater andmore extensive conditional instability (CI) and CSI. CSI is released by ascending air parcels in the cloud head in two of the sting-jet storms and by descending air parcels in the other sting-jet storm. By contrast, only weak CI to ascending air parcels is present at the cloud-head tip in the non-sting-jet storm. CSI released by descending air parcels, as diagnosed by decaying downdraught slantwise convective available potential energy (DSCAPE), is collocated with the sting jets in all three sting-jet storms and has a localisedmaximum in two of them. Consistent evolutions of saturated moist potential vorticity are found.We conclude that CSI release has a role in the generation of the sting jet, that the sting jet may be driven by the release of instability to both ascending and descending parcels, and that DSCAPE could be used as a discriminating diagnostic for the sting jet based on these four case-studies.

Conditional transgenic expression of fibroblast growth factor 9 in the adult mouse heart reduces heart failure mortality after myocardial infarction

BACKGROUND: Fibroblast growth factor 9 (FGF9) is secreted from bone marrow cells, which have been shown to improve systolic function after myocardial infarction (MI) in a clinical trial. FGF9 promotes cardiac vascularization during embryonic development but is only weakly expressed in the adult heart. METHODS AND RESULTS: We used a tetracycline-responsive binary transgene system based on the α-myosin heavy chain promoter to test whether conditional expression of FGF9 in the adult myocardium supports adaptation after MI. In sham-operated mice, transgenic FGF9 stimulated left ventricular hypertrophy with microvessel expansion and preserved systolic and diastolic function. After coronary artery ligation, transgenic FGF9 enhanced hypertrophy of the noninfarcted left ventricular myocardium with increased microvessel density, reduced interstitial fibrosis, attenuated fetal gene expression, and improved systolic function. Heart failure mortality after MI was markedly reduced by transgenic FGF9, whereas rupture rates were not affected. Adenoviral FGF9 gene transfer after MI similarly promoted left ventricular hypertrophy with improved systolic function and reduced heart failure mortality. Mechanistically, FGF9 stimulated proliferation and network formation of endothelial cells but induced no direct hypertrophic effects in neonatal or adult rat cardiomyocytes in vitro. FGF9-stimulated endothelial cell supernatants, however, induced cardiomyocyte hypertrophy via paracrine release of bone morphogenetic protein 6. In accord with this observation, expression of bone morphogenetic protein 6 and phosphorylation of its downstream targets SMAD1/5 were increased in the myocardium of FGF9 transgenic mice. CONCLUSIONS: Conditional expression of FGF9 promotes myocardial vascularization and hypertrophy with enhanced systolic function and reduced heart failure mortality after MI. These observations suggest a previously unrecognized therapeutic potential for FGF9 after MI.

Analysis and manipulation of the structure of odor plumes from a piezo-electric release system and measurements of upwind flight of male Almond Moths, Cadra cautella, to pheromone plumes

We investigated the plume structure of a piezo-electric sprayer system, set up to release ethanol in a wind tunnel, using a fast response mini-photoionizaton detector. We recorded the plume structure of four different piezo-sprayer configurations: the sprayer alone; with a 1.6-mm steel mesh shield; with a 3.2-mm steel mesh shield; and with a 5 cm circular upwind baffle. We measured a 12 × 12-mm core at the center of the plume, and both a horizontal and vertical cross-section of the plume, all at 100-, 200-, and 400-mm downwind of the odor source. Significant differences in plume structure were found among all configurations in terms of conditional relative mean concentration, intermittency, ratio of peak concentration to conditional mean concentration, and cross-sectional area of the plume. We then measured the flight responses of the almond moth, Cadra cautella, to odor plumes generated with the sprayer alone, and with the upwind baffle piezo-sprayer configuration, releasing a 13:1 ratio of (9Z,12E)-tetradecadienyl acetate and (Z)-9-tetradecenyl acetate diluted in ethanol at release rates of 1, 10, 100, and 1,000 pg/min. For each configuration, differences in pheromone release rate resulted in significant differences in the proportions of moths performing oriented flight and landing behaviors. Additionally, there were apparent differences in the moths’ behaviors between the two sprayer configurations, although this requires confirmation with further experiments. This study provides evidence that both pheromone concentration and plume structure affect moth orientation behavior and demonstrates that care is needed when setting up experiments that use a piezo-electric release system to ensure the optimal conditions for behavioral observations.
