Ubiquitin-related processes and innate immunity in C. elegans.

Innate immunity is an evolutionary ancient defence strategy that serves to eliminate infectious agents while maintaining host health. It involves a complex network of sensors, signaling proteins and immune effectors that detect the danger, then relay and execute the immune programme. Post-translational modifications relying on conserved ubiquitin and ubiquitin-like proteins are an integral part of the system. Studies using invertebrate models of infection, such as the nematode Caenorhabditis elegans, have greatly contributed to our understanding of how ubiquitin-related processes act in immune sensing, regulate immune signaling pathways, and participate to host defence responses. This review highlights the interest of working with a genetically tractable model organism and illustrates how C. elegans has been used to identify ubiquitin-dependent immune mechanisms, discover novel ubiquitin-based resistance strategies that mediate pathogen clearance, and unravel the role of ubiquitin-related processes in tolerance, preserving host fitness during pathogen attack. Special emphasis is placed on processes that are conserved in mammals.

Variables Associated With the Subjective Experience of Coercive Measures in Psychiatric Inpatients: A Systematic Review.

OBJECTIVE: This systematic review presents evidence regarding factors that may influence the patient's subjective experience of an episode of mechanical restraint, seclusion, or forced administration of medication. METHOD: Two authors searched CINAHL, PubMed, SCOPUS, Web of Science, and Psych-Info, considering published studies between 1 January 1992 and 1 February 2016. Based on the inclusion criteria and methodological quality, 34 studies were selected, reporting a total sample of 1,869 participants. RESULTS: The results showed that the provision of information, contact and interaction with staff, and adequate communication with professionals are factors that influence the subjective experience of these measures. Humane treatment, respect, and staff support are also associated with a better experience, and debriefing is an important procedure/technique to reduce the emotional impact of these measures. Likewise, the quality of the working and physical environment and some individual and treatment variables were related to the experience of these measures. There are different results in relation to the most frequently associated experiences and, despite some data that indicate positive experiences, the evidence shows such experiences to be predominantly negative and frequently with adverse consequences. It seems that patients find forced medication and seclusion to be more tolerable than mechanical restraint and combined measures. CONCLUSIONS: It appears that the role of the staff and the environmental conditions, which are potentially modifiable, affect the subjective experience of these measures. There was considerable heterogeneity among studies in terms of coercive measures experienced by participants and study designs.

Effectiveness of a Multimodal Intervention Program for Restraint Prevention in an Acute Spanish Psychiatric Ward.

BACKGROUND: International recommendations have called to implement strategies to reduce the use of coercion in psychiatric settings. However, in Spain there is a lack of research about intervention programs to reduce mechanical restraint in acute psychiatric units. OBJECTIVE: The aim of this study was to evaluate the effectiveness of a multimodal intervention program based on the principles of six core strategies to reduce the frequency of use of mechanical restraint in an acute psychiatric ward. DESIGN: The design was a retrospective analysis of the frequency and duration of episodes of mechanical restraint prior to the intervention program (2012) and during the intervention program (2013) in one acute psychiatric ward. The intervention was governed by four strategies: (1) leadership and organizational changes, (2) registration and monitoring of risk patients, (3) staff training, and (4) involving patients in the treatment program. RESULTS: There was a significant difference between the mean number of monthly episodes of mechanical restraint per 1,000 patient days, pre-intervention (18.54 ± 8.78) compared with postintervention (8.53 ± 7.00; p = .005). We found the probability that mechanical restraint would occur in a hospital admission decreased after performing the intervention (odds ratio = .587; confidence interval = 0.411-0.838; p = .003) after adjusting for confounding variables. The total percentage of restrained patients fell from 15.07% to 9.74%. CONCLUSIONS: The main implication of the study is to support the effectiveness of specific intervention programs based on different measures to reduce mechanical restraint and without contemplating all the strategies that are considered effective.

The therapeutic relationship from the perspective of patients and nurses in the first days of admission: A cross-sectional study in acute mental health units.

The therapeutic relationship (TR) is essential in mental health nursing care and plays a fundamental role in the understanding and treatment of the patient's health status. Despite being a bidirectional construct, limited evidence is available to shed light on this issue in mental health units and even less so in the first days of admission. This study aimed to examine the association and differences between nurses' and patients' perspectives on the establishment of the therapeutic relationship in acute mental health units during the first days of hospitalization. A cross-sectional study was carried out in 12 Spanish mental health units. Data were collected from patients and nurses using the Working Alliance Inventory-Short (WAI-S) questionnaire. A total of 234 cases were analysed, including 234 patients and 58 nurses. The results showed a positive association between nurses' and patients' perspectives on the therapeutic relationship, but also revealed significant differences on each WAI-S dimension. Nurses assigned higher scores compared to patients on the perception of the quality of the therapeutic relationship. The dimensions with the greatest weight from the patients' perspective regarding the quality of the therapeutic relationship were the perception of greater agreement on goals and tasks among nurses. This study demonstrates the importance of establishing shared goals and tasks with nurses from the first days of hospitalization to improve the quality of the therapeutic relationship as perceived by patients. These findings underline the need to consider the different perspectives of both parties to promote a high-quality therapeutic relationship.

Title: L'immunité entraînée - Une stratégie émergente contre l'antibiorésistance. Abstract: Les étudiants de Polytech Nice Sophia (PNS) en Génie Biologique 5A ont exploré trois projets prometteurs. L'équipe pédagogique qui les a encadrés est composée de Cercina ONESTO et Nicole ARRIGHI, enseignants-chercheurs à PNS, et du trinome Céline PISIBON, Imène KROSSA et Juan GARCIA-SANCHEZ, doctorants et post-doctorants du Centre Méditerranéen de Médecine Moléculaire de Nice. Dès le début du cursus d'ingénieur, les étudiants suivent un cours d'introduction à la recherche. Plus ils avancent dans le cursus, plus ils se perfectionnent dans l'analyse de l'actualité scientifique de leur spécialité. Dans la mineure Pharmacologie et Biotechnologies, ils cernent les limites d'un traitement, puis ils réfléchissent en équipes à une nouvelle piste thérapeutique. Ainsi, ils anticipent l'innovation en santé, l'imaginent et la créent pour devenir les ingénieurs en santé de demain.

Characteristics of psychiatric hospitalizations with multiple mechanical restraint episodes versus hospitalization with a single mechanical restraint episode.

We investigated the characteristics of multiple episodes of mechanical restraint versus a single episode in a psychiatric ward of a public general hospital. The following characteristics were associated with multiple restraints: young age, length of hospital stay, not being readmitted within 30 days from previous discharge, and admission in the previous year before the implementation of an intervention program to reduce mechanical restraint. The study suggests that both organizational factors and patients' disturbed behaviour are associated with the risk of being mechanically restrained several times.

Effects of a Regulatory Protocol for Mechanical Restraint and Coercion in a Spanish Psychiatric Ward.

PURPOSE: There is still limited information on what type of measures are most efficient to reduce coercion. The aim of this study was to determine if the introduction of a new regulatory protocol in a specific psychiatric ward in Andalusia (Spain) contributed to reducing the use of mechanical restraint. DESIGN AND METHODS: The study included a comparison of two time periods: 2005 (one year before the implementation of the new regulatory protocol) and 2012, in all hospitalized patients (N=1,094). The study also analyzes with logistic regression the variables related to a shorter duration of mechanical restraint. FINDINGS: Mechanical restraint rate per year was reduced, not significantly, from 18.2% to 15.1%. The average duration of each mechanical restraint episode was significantly reduced from 27.91 to 15.33 hr. The following variables have been associated with a shorter period of coercion: being female and the year of restraint (2012). PRACTICE IMPLICATIONS: Specific plans are required, including different interventions, in order to achieve marked reduction in the use of coercive measures.
