Annals of General Psychiatry , 2011, DOI: 10.1186/1744-859x-10-4
Abstract: A retrospective study on chemical restraint was performed in the 11-bed psychiatric ward of the General Hospital of Arta, in northwestern Greece. All admissions over a 2-year-period (from March 2008 to March 2010) were examined.Chemical restraint was applied in 33 cases (10.5% of total admissions). From a total of 82 injections, 22 involved a benzodiazepine and/or levomepromazine, whereas 60 injections involved an antipsychotic agent, almost exclusively haloperidol (96.7% of cases), usually in combination with a benzodiazepine (61.7% of cases). In 36.4% of cases the patient was further subjected to restraint or seclusion.In our unit, clinicians prefer the combined antipsychotic/benzodiazepine regimen for the management of patients' acute agitation and violent behaviour. Conventional antipsychotics are administrated almost exclusively and in a significant proportion of cases further coercive measures are applied. Studies on the practice of chemical restraint should be regularly performed in clinical settings.Coercive measures are commonly used in psychiatric treatment for the management of behaviour in patients who are disturbed, although the need for alternatives has been widely recognised [1]. Most authors focus on seclusion and physical restraint, whereas chemical (pharmaceutical) restraint or rapid tranquilisation has gained little attention in the recent literature. We have previously reported on the practice of restraint and seclusion in Greece [2] and the patients and families attitudes towards coercive measures [3]. Here, we report on the practice of chemical restraint in a psychiatric ward within a general hospital.A total of 314 admissions in the 11-bed psychiatric ward of the General Hospital of Arta in northwestern Greece from a 2-year-period (March 2008 to March 2010) were examined retrospectively. Rapid tranquilisation (defined as emergency intramuscular drug administration for the management of patients' acute agitation and violent behaviour) was appli

Abstract: Objectives. Treatment of psychotic disorders is impended by high rates of disengagement from mental health services and poor adherence to antipsychotic medication. This study examined the engagement rates of psychotic patients with a community mental health service during a 5-year period. Methods. The Mobile Mental Health Unit of Ioannina and Thesprotia (MMHU I-T) delivers services in remote, rural, mountainous areas using the resources of the primary care system. Clinical and demographic information for patients with a diagnosis of schizophrenia and related psychoses was obtained from the medical records of our unit. Results. A total of 74 psychotic patients initially engaged in treatment with our unit. In half of cases treatment was home-based. With the exclusion of patients who died or discharged, engagement rates were 67.2%. Statistical analysis was performed for 64 patients, and no differences were found between engaged and disengaged patients regarding clinical and demographic parameters. All engaged patients regularly refilled their antipsychotic prescriptions. Conclusion. Engagement rates in our study were comparable to previous research, involving urban settings and shorter follow-up duration. Community mental health teams may ensure treatment continuation for psychotic patients in deprived, remote areas. This is important for low-income countries, affected by economic crisis, such as Greece. 1. Introduction Schizophrenia and related disorders are chronic and disabling and have a major impact on the person, the family, and the society in general. Continuity of care is considered essential in the effective management of such long-term disorders by service users, clinicians, and health care policy makers [1]. Previous studies have suggested that continuity of care is positively associated with health outcomes among persons with severe mental illness [2]. More recently, continuity of care was linked to better social functioning of people with chronic psychotic disorders [3]. However, despite the availability of effective pharmacological and psychosocial treatments for the management of psychotic disorders, treatment is impended by high rates of disengagement from mental health services and poor adherence to antipsychotic medication. Treatment discontinuation has severe consequences for the patients, such as relapse, hospitalization, homelessness, suicide, and violence [4, 5]. This may be particularly the case of psychotic patients living in poor and deprived remote rural areas who may not receive appropriate mental health care. Evidence from

On a conjecture regarding the upper graph box dimension of bounded subsets of the real line
Vaios Laschos,Giorgos Kelgiannhs
Mathematics , 2012,
Abstract: Let X \subset R be a bounded set; we introduce a formula that calculates the upper graph box dimension of X (i.e.the supremum of the upper box dimension of the graph over all uniformly continuous functions defined on X). We demonstrate the strength of the formula by calculating the upper graph box dimension for some sets and by giving an "one line" proof, alternative to the one given in [1], of the fact that if X has finitely many isolated points then its upper graph box dimension is equal to the upper box dimension plus one. Furthermore we construct a collection of sets X with infinitely many isolated points, having upper box dimension a taking values from zero to one while their graph box dimension takes any value in [max{2a,1},a + 1], answering this way, negatively to a conjecture posed in [1].
Relations between $\mathcal{L}^p$- and Pointwise Convergence of Families of Functions Indexed by the Unit Interval
Vaios Laschos,Christian M?nch
Mathematics , 2012,
Abstract: We construct a variety of mappings of the unit interval into $\mathcal{L}^p([0,1])$ to generalize classical examples of $\mathcal{L}^p$-convergence of sequences of functions with simultaneous pointwise divergence. By establishing relations between the regularity of the functions in the image of the mappings and the topology of $[0,1]$, we obtain examples which are $\mathcal{L}^p$-continuous but exhibit discontinuity in a pointwise sense to different degrees. We conclude by proving an Egorov-type theorem, namely that if almost every function in the image is continuous, then we can remove a set of arbitrarily small measure from the index set $[0,1]$ and establish pointwise limits for all functions in the remaining image.
Large deviations for empirical measures generated by Gibbs measures with singular energy functionals
Paul Dupuis,Vaios Laschos,Kavita Ramanan
Mathematics , 2015,
Abstract: We establish large deviation principles (LDPs) for empirical measures associated with a sequence of Gibbs distributions on $n$-particle configurations, each of which is defined in terms of an inverse temperature $\beta_n$ and an energy functional that is the sum of a (possibly singular) interaction and confining potential. Under fairly general assumptions on the potentials, we establish LDPs both with speeds $\beta_n/n \rightarrow \infty$, in which case the rate function is expressed in terms of a functional involving the potentials, and with the speed $\beta_n =n$, when the rate function contains an additional entropic term. Such LDPs are motivated by questions arising in random matrix theory, sampling and simulated annealing. Our approach, which uses the weak convergence methods developed in "A weak convergence approach to the theory of large deviations", establishes large deviation principles with respect to stronger, Wasserstein-type topologies, thus resolving an open question in "First order global asymptotics for Calogero-Sutherland gases". It also provides a common framework for the analysis of LDPs with all speeds, and includes cases not covered due to technical reasons in previous works.
Wasserstein gradient flows from large deviations of thermodynamic limits
Manh Hong Duong,Vaios Laschos,Michiel Renger
Mathematics , 2012,
Abstract: We study the Fokker-Planck equation as the hydrodynamic limit of a stochastic particle system on one hand and as a Wasserstein gradient flow on the other. We write the rate functional, that characterizes the large deviations from the hydrodynamic limit, in a way that the free energy appears explicitly. Next we use this formulation via the contraction principle to prove that the discreet time rate functional is asymptotically equivalent in the Gamma-convergence sense to the functional derived from the Wasserstein gradient discretization scheme.

Abstract: background and objectives: attention-deficit/hyperactivity disorder (adhd) symptoms and other mental health problems appear early in life and proper treatment is essential for a positive long-term outcome. the present study examines the level of agreement, and potential gender differences, between parents' and teachers' reports of adhd symptoms and other mental health problems in 305 greek children aged between 6-9 years. methods: parents and teachers of 147 boys and 158 girls attending the first three grades of 10 primary schools in the wider area of northern greece completed the strength and difficulties questionnaire (sdq- goodman, 1997) and the child attention profile (cap- barkley, 1990). results: the level of agreement between parents' and teachers' reports was low to moderate for the sdq (0.16-0.34) and satisfactory for the cap (0.60-0.66). parents reported more hyperactivity, emotional, and conduct problems than teachers according to sdq and more overactivity and attention-deficit with hyperactivity according to cap. gender differences in ratings were found as well, since boys were reported as being more hyperactive according to sdq and as having more overactivity and attention-deficit with hyperactivity according to cap than girls. conclusions: findings are discussed in terms of the importance of using multiple informants to gather data on disruptive behaviour through rating scales.
