Among the youths referred to our Psychiatric Inpatient Emergency Service, we
focused on bipolar disorder (BD), to explore predictive elements for the outcome.
Fifty-one patients (30 males, 21 females, age range 8-18 years, mean age 14.2 ±
3.1 years) received a diagnosis of BD, according to historical information,
prolonged observations, and a structured clinical interview (K-SADS-PL).
Twenty-seven patients (52.9%) were responders at the end of hospitalization
according to CGI-I 1 or 2 and 50% decrease of both Brief Psychiatric Rating Scale
(BPRS) and Young Mania Rating Scale (YMRS). Responders received a longer
hospitalization. Non responders were more severe at baseline, had higher scores
at BPRS (namely positive symptoms), and were more aggressive.
Environmental/social stressors and comorbidities were frequent, but they did not
affect the outcome. In summary, BD in emergency settings may represent a subtype
with clinical and therapeutic peculiarities, and specific challenges for mental
health services
Psychoanalysis for a new humanism: Embodied testimony, connectedness, memory and forgiveness for a “persistence of the human”
No full textIn proposing a refounding of psychoanalysis within a humanist perspective, the author suggests a comparison between Elie
Wiesel’s discussion of concepts such as witnessing, testimony, and memory as redemption, and Sandor Ferenczi’s idea of
the therapist as “benevolent and useful witness,” who, thanks to his/her true empathic and committed participation, in
contrast to Freud’s neutrality, enables the patient to achieve real awareness of the split parts within him- or herself, as well
as an integration of the fragmentation due to trauma. Against “indifference,” the practice of connectedness, responsibility,
memory, love, and forgiveness as true elaboration of trauma and “going beyond” are proposed as tools towards a
“persistence of the human” in a world of increasing dehumanization
The relaxed Dirichlet energy of mappings into a manifold
No full textLet Y be a smooth 1-connected compact oriented manifold without boundary,
such that its 2-homology group has no torsion. We characterize in any dimension n the weak
W^(1,2)(Bn, Y) lower semicontinuous envelope of the Dirichlet integral of Sobolev maps in
W^(1,2)(Bn, Y)
Maps of bounded variation with values into a manifold: total variation and relaxed energy
No full textRelaxation results for a class of functionals with linear growth defined on manifold constrained mappings
No full textIn this paper we study the lower semicontinuous envelope of a class of functionals with linear growth
defined on mappings from the n-dimensional ball into R^N that are constrained to take values into a
smooth submanifold Y of R^N
Weak and strong density results for the Dirichlet energy
No full textLet Y be a smooth oriented Riemannian manifold which is compact, connected, without
boundary and with second homology group without torsion. In this paper we characterize the sequential
weak closure of smooth graphs in Bn ×Y with equibounded Dirichlet energies, Bn being
the unit ball in Rn. More precisely, weak limits of graphs of smooth maps uk : Bn \to Y with
equibounded Dirichlet integral give rise to elements of the space cart^(2,1)(Bn ×Y).
In this paper we prove that every element T in cart^(2,1)(Bn×Y) is the weak limit of a sequence {uk}
of smooth graphs with equibounded Dirichlet energies. Moreover, in dimension n = 2, we show
that the sequence {uk} can be chosen in such a way that the energy of uk converges to the energy
of T
Graphs of W^(1,1)-maps with values into S^1: relaxed energies, minimal connections and lifting
No full textThe aim of this paper is to link the analytic results of Brezis et al., Demengel and
Ignat relative to W^(1,1)-mappings from B^n into S^1 to the measure-theoretical
geometric results in our previous work. The paper also contains a few remarks about
mappings in W^(1,p) with values in S^2
Laminarina e zolfo nel contenimento dell'oidio del melo in Trentino
No full textNegli anni 2022 e 2023 è stata condotta in Trentino una sperimentazione di campo per valutare la laminarina, induttore di resistenza nelle piante, nel contenimento dell’oidio del melo. Le prove sono state realizzate in un meleto della cv Gala con un disegno sperimentale a blocchi randomizzati. La laminarina (Vacciplant®), applicata con un intervallo di tempo tra 7 e 10 giorni, è stata confrontata con zolfo (Thiopron®) e la sua miscela con zolfo. Tutte le tesi sono state confrontate tra loro e con una strategia di difesa standard basata su fungicidi di sintesi attualmente registrati su melo. In entrambi gli anni di prova, al rilievo finale, la tesi testimone non trattata mostrava la quasi totalità delle foglie colpite (>90%) con valori elevati di gravità (57% nel 2022, 78% nel 2023). La laminarina in miscela con zolfo, similarmente alla tesi standard chimica, ha sempre garantito i migliori valori di efficacia (46% diffusione e 11% gravità nel 2022, 35% e 10% nel 2023). L’impiego in fitoiatria della laminarina quale induttore di resistenza, potrebbe contribuire a differenziare l’approccio alla difesa antioidica del melo. Sarà necessario raccogliere ulteriori evidenze sperimentali per ottimizzarne l’utilizzo in pieno campoIn 2022 and 2023 a field trial was carried out to evaluate laminarin, a natural elicitor of the plant defence, against apple powdery mildew. The trial was settled in an apple orchard of Gala cultivar. The experiment design was a randomized block with five treatments; laminarin (Vacciplant®) with timing of 7-10 days, and sulfur (Thiopron®) both used alone, their tank mixture, a synthetic fungicides-based protection strategy and an untreated. At the end of experiments, the untreated suffered heavy damages on leaves by powdery mildew with incidence values higher than 90% in both years and severity of 57% in 2022 and 78% in 2023 respectively. The mixture of laminarin and sulfur scored the higher protection results in a similar way to chemical products. Laminarin as elicitor in inducing resistance in plants could contribuite to realize a different type of approach in crop protection. It will be necessary to acquire more evidence to better understand their utilization in the fiel
The Dirichlet energy of mappings from B^3 into a manifold: density results and gap phenomenon
No full textWeak limits of graphs of smooth maps u_k:B^n\to Y with equibounded Dirichlet integral give rise to elements of the space cart^{2,1}(B^n x Y). We assume that the 2-homology group of Y has no torsion and that the Hurewicz homomorphism p_2(Y)\to H_2(Y,Q) is injective. Then, in dimension n=3, we prove that every element T in
cart^{2,1}(B^3 x Y), which has no singular vertical
part, can be approximated weakly in the sense of currents by a sequence of smooth graphs {u_k} with Dirichlet energies
converging to the energy of T. We also show that the
injectivity hypothesis on the Hurewicz map cannot be removed. We finally show that a similar topological obstruction on the target manifold holds for the approximation problem of the area

On sequences of maps into a manifold with equibounded W1/2-energies
No full textAbstractWe characterize weak limits of sequences of smooth functions from Bn into suitable manifolds Y with equibounded W1/2-energies, the relaxed W1/2-energy and we prove strong density of smooth maps. We then obtain the weak sequential density of smooth maps in W1/2(Bn,Y) and a criterion for strong density of smooth maps
