Depression in cancer patients: a critical review
Cancer patients experience several stressors and emotional upheavals. Fear of death, interruption of life plans, changes in body image and self-esteem, changes in social role and lifestyle are all important issues to be faced. Moreover, Depressive Disorders may impact the course of the disease and compliance. The cost and prevalence, the impairment caused, and the diagnostic and therapeutic uncertainty surrounding depressive symptoms among cancer patients make these conditions a priority for research. In this article we discuss recent data, focusing on detection of Depressive Disorders, biological correlates, treatments and unmet needs of depressed cancer patients
Cognitive Behavioral Therapy in Movement Disorders. A Review
In addition to motor symptoms, patients with movement disorders often complain of psychiatric disturbances, including mood, anxiety, and impulse-control disorders and psychosis. These abnormalities are often misdiagnosed and left untreated, thus resulting in a worse prognosis and lower quality of life. Besides the use of standard pharmacological treatments, psychiatric abnormalities can be treated by means of nonpharmacological approaches. These approaches include various types of psychological therapies, the most widely used being cognitive behavioral therapy (CBT). We reviewed all articles, conducted until 2014, that contained primary data derived from clinical trials and case reports on the effect of CBT in the most common movement disorders. One randomized, controlled study and several uncontrolled studies on the efficacy of CBT in Parkinson's disease (PD) have shown a short-term benefit of depression and anxiety. In Tourette's syndrome (TS), CBT has been assessed in a number of large controlled clinical trials that have demonstrated an improvement in psychiatric disturbances and tics. There are no controlled studies on the efficacy of CBT in other types of movement disorders, such as dystonia, Huntington's disease, and essential tremor. Only a limited number of studies have evaluated the efficacy of CBT in the management of psychiatric disorders in movement disorders. The evidence available suggests that CBT is useful in TS and probably useful in PD. We recommend the planning of randomized, controlled clinical trials to investigate the effects of CBT and group CBT in the treatment of psychiatric disturbances in movement disorders
Free will, neuroscience, and choice: towards a decisional capacity model for insanity defense evaluations
Il libero arbitrio è stato spesso considerato una tematica centrale nella dottrina della responsabilità criminale. Ciononostante,
il concetto stesso di libero arbitrio presenta intrinseche problematiche nella sua definizione teorica e applicazione pratica in un contesto clinico/
forense ed è intensamente dibattuto. Nello specifico, l’esistenza stessa del libero arbitrio è stata recentemente posta in discussione anche
sulla base di alcune evidenze sperimentali neuroscientifiche. Questo dibattito ha implicazioni significative in quei campi in cui l’associazione
tra libertà di scelta è comportamento costituisce il focus di interesse, quali la psichiatria forense. Esiste inoltre una sorta di conflittualità
tra la centralità e concezione teorica del libero arbitrio (free will) e il suo status e applicazione pratica. Questo problema ha bisogno di
essere affrontato, specialmente all’interno della psichiatria forense, dal momento che risulta rilevante per l’effettiva valutazione dell’infermità
di mente. Nel presente articolo cercheremo di rendere operativo il concetto del “libero arbitrio” utilizzando il modello a quattro dimensioni
utilizzato per la capacità decisionale, che può essere impiegato nella valutazione forense dell’infermità di mente. Descriveremo i
suoi vantaggi e applicazioni per guidare la valutazione dell’infermità di mente. Mentre il libero arbitrio è spesso considerato problematico
dal punto di vista delle neuroscienze, questo modello, a nostro avviso, è compatibile con le neuroscienze; inoltre, le valutazioni che utilizzino
questo modello possono anche essere arricchite e rafforzate dalle scoperte neuro scientifiche, per esempio riguardo il controllo inibitorioFree will has often been considered central to criminal responsibility. Yet, the concept of free will is also difficult to define and
operationalize, and, moreover, it is intensely debated. In particular, the very existence of free will has been denied based on recent neuroscience
findings. This debate has significant implications on those fields in which the link between free will and behaviour is the main focus
of interest, such as forensic psychiatry. In fact, a tension is often experienced between the centrality of the notion of free will on the one hand,
and its controversial status on the other. This tension needs to be addressed, especially in forensic psychiatry, since it is relevant for actual assessments
of legal insanity. In the present paper we will try to operationalize “free will” using a fourpartite decision-making capacity model,
which can be used in forensic assessment of insanity. We will describe its advantages and application to guide mental insanity assessments.
Whereas free will is often considered problematic from a neuroscience perspective, this model, we argue, is compatible with neuroscience;
moreover, evaluations using this model can also be informed and strengthened by neuroscientific findings, for example regarding inhibitory
control
What every psychiatrist should know about PANDAS: a review
The term Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus infections (PANDAS) was coined by Swedo et al. in 1998 to describe a subset of childhood obsessive-compulsive disorders (OCD) and tic disorders triggered by group-A beta-hemolytic Streptococcus pyogenes infection. Like adult OCD, PANDAS is associated with basal ganglia dysfunction. Other putative pathogenetic mechanisms of PANDAS include molecular mimicry and autoimmune-mediated altered neuronal signaling, involving calcium-calmodulin dependent protein (CaM) kinase II activity. Nonetheless the contrasting results from numerous studies provide no consensus on whether PANDAS should be considered as a specific nosological entity or simply a useful research framework. Herein we discuss available data that could provide insight into pathophysiology of adult OCD, or might explain cases of treatment-resistance. We also review the latest research findings on diagnostic and treatment
The admission experience survey italian version (I-AES). a factor analytic study on a sample of 156 acute psychiatric in-patients
Coercive treatments are often regarded as an inevitable and yet highly debated feature of psychiatric care. Perceived coercion is often reported by patients involuntarily committed as well as their voluntary counterparts. The Admission Experience Survey (AES) is a reliable tool for measuring perceived coercion in mental hospital admission. We developed the Italian AES (I-AES) through translation back-translation and administered it to 156 acutely hospitalized patients (48% women, 69% voluntarily committed) in two university hospitals in Rome (Policlinico Umberto I, Sant'Andrea Hospital). A principal component analysis (PCA) with equamax rotation was conducted. The I-AES showed good internal consistency (Cronbach's alpha = 0.90); Guttmann split-half relia- bility coefficient was 0.90. AES total score significantly differed between voluntary and involuntary committed patients (5.08 ± 4.1 vs. 8.1 ± 4.9, p < .05). PCA disclosed a three-factor solution explaining 59.3 of the variance. Some discrepancies were found between the factor structure of the I-AES and the original version. I- AES total score was positively associated with numbers of previous involuntarily hospitalization (r = 0.20, p < .05) and psychiatric symptoms' severity (r = 0.22, p < .02). I-AES and its proposed new factor structure proved to be reliable to assess perceived coercion in mental hospital admission. Consequently, it may represent a helpful instrument for the study and reduction of patients' levels of perceived coercion

Aripiprazole Augmentation in Patients with Resistant Obsessive Compulsive Disorder: a Pilot Study
Background: Antipsychotic augmentation is an effective treatment intervention for Obsessive Compulsive Disorder (OCD) patients resistant to Selective Serotonin Reuptake Inhibitors (SSRI) agents. This pilot study was conducted to evaluate the effectiveness and tolerability of Aripiprazole for the augmentation of standard treatments in patients with resistant OCD. Methods: Twenty patients diagnosed with OCD according to DSM-IV TR criteria and having a history of resistance to standard pharmacological treatment were included in the study. Aripiprazole was added to ongoing SSRI or clomipramine treatment with a starting dose of 5 mg/day and titrated up to a maximum of 20 mg/day (mean dose 12.62 mg ± 4.25). Efficacy was assessed with the Yale-Brown obsessive compulsive scale (Y-BOCS) and the Clinical Global Improvement-severity scale (CGI-S) at baseline and at week 12 of Aripiprazole augmentation. Side effects were monitored by the Udvalg for Kliniske Undersogelser (UKU) side effect rating scale. Results: All 20 subjects enrolled in our study completed the full 12-week course of treatment. A significant improvement over the 12-week study period was observed (paired t-test for mean Y-BOCS total score at week 12 as compared with baseline - all patients: t = 13.146, d.f. = 19, p= 0.0001). Aripiprazole was generally well tolerated and no changes were observed in vital signs. The most commonly observed side effects after the introduction of the augmenting agent included: akathysia, nausea/vomiting, hyperkinesia, tension/inner unrest, tremors, asthenia/lassitude/increased fatiguability. Conclusions: Although results of this pilot study are preliminary and require confirmation in randomized controlled trials, our experience suggested that Aripiprazole is effective and well-tolerated as an augmenting agent in patients with treatment resistant OCD. © Delle Chiaie et al
Neutron - mirror neutron mixing and neutron stars
The oscillation of neutrons into mirror neutrons , their mass
degenerate partners from dark mirror sector, can have interesting implications
for neutron stars: an ordinary neutron star could gradually transform into a
mixed star consisting in part of mirror dark matter. Mixed stars can be
detectable as twin partners of ordinary neutron stars: namely, there can exist
compact stars with the same masses but having different radii. For a given
equation of state (identical between the ordinary and mirror components), the
mass and radius of a mixed star depend on the proportion between the ordinary
and mirror components in its interior which in turn depends on its age. If proportion between two fractions can be reached asymptotically in
time, then the maximum mass of such "maximally mixed stars" should be
times smaller than that of ordinary neutron star while the stars exceeding a
critical mass value should collapse in black holes
after certain time. We evaluate the evolution time and discuss the implications
of transition for the pulsar observations as well as for the
gravitational waves from the neutron star mergers and associated
electromagnetic signals.Comment: 18 pages, 6 figure
