Compulsive Hoarding Symptoms and the Role of Mindfulness Skills During Social Distancing for the COVID-19 Pandemic: An Exploratory Survey
People reporting compulsive hoarding symptoms (CHS) have lower mindfulness skills than those without such symptoms. Mindfulness skills can have the role of a protective buffer against stressful periods. The quarantine imposed to contain the COVID-19 spread had a negative impact on daily habits and healthy behaviors (including social interactions). An increased attachment to objects might be one of the under-recognized psychological consequences of these difficult times, yet no study focused on CHS. Through an online survey in men who were on quarantine during the pandemic, this exploratory survey examined the prevalence of men reporting CHS during this period and explored the role of mindfulness skills on CHS controlling for anxious-depressive/stress symptoms. Forty-three men from the general population completed the Obsessive Compulsive Inventory-Revised (OCI-R), Cognitive and Affective Mindfulness Scale-Revised (CAMS-R) and Depression Anxiety Stress Scales-21 (DASS-21). Twenty-eight percent reported CHS. No differences on the scores of the questionnaires emerged between men with and without CHS, except on CAMS-R Attention scores. In a logistic regression analysis lower CAMS-R Attention scores predicted CHS (β = −0.34, p = 0.03). This is the first, yet preliminary investigation on CHS during quarantine. The prevalence of CHS appears higher than the rates (4%) reported in the last years before the COVID-19 outbreak. Perhaps people showed more intense hoarding tendencies during quarantine/social distancing, and this pattern should be monitored. Larger samples, longitudinal designs and clinician-rated instruments are needed to support or not our findings
A Pilot Study of Gender Differences in Sexual Arousal of Patients With OCD: The Moderator Roles of Attachment and Contamination Symptoms
Sexual arousal is often impaired in patients with obsessive–compulsive disorder (OCD).
However, little is known about the factors related to this impairment: no study focused on
the role of gender-based effects of attachment styles and contamination symptoms. The
Dual Control Model assumes three processes driving sexual arousal: sexual excitation
(SE), sexual inhibition (SI) due to threat of performance failure, and SI due to threat
of performance consequences (e.g., getting contaminated with sexually transmitted
diseases). In a group of OCD patients, we hypothesized that (a) women report lower SE
and higher SI thanmen; (b) patients with insecure (both anxious and avoidant) attachment
styles show lower SE and higher SI; (c) attachment styles moderate the relation between
gender and sexual arousal (respectively, for women, higher attachment anxiety, and for
men higher attachment avoidance were related to impaired sexual arousal (higher SE and
SI) controlling for OCD severity); and (d) contamination symptoms moderate the relation
between gender and sexual impairment (women with contamination symptoms show
impaired sexual arousal). Seventy-two OCD patients (37.50% women) completed the
Obsessive–Compulsive Inventory-Revised, Attachment Styles Questionnaire and Sexual
Inhibition/Sexual Excitation Scales. In contrast with our hypotheses, women reported
higher SE and lower SI due to threat of performance consequences than men. Patients
with higher attachment avoidance (discomfort with intimacy) but also confidence in self
and others had higher SE. Women with attachment avoidance (i.e., discomfort with
intimacy) had lower SE, while women with attachment anxiety (i.e., preoccupations
with relationships) had higher SI due to negative performance consequences. Women
with contamination symptoms had higher SI due to performance failure but lower SI
due to performance consequences. The present preliminary findings suggest that sexual
arousal impairment should be evaluated during the assessment of OCD patients, and
gender-based effects of attachment styles and contamination symptoms should be
considered during personalized treatment planning
Prevalence of psychiatric disorders in thyroid diseased patients.
Several studies have underlined the high prevalence of psychiatric symptoms and disorders in thyroid diseases. The aim of this study was to evaluate the prevalence of psychiatric disorders in 93 inpatients affected by different thyroid diseases during their lifetimes, by means of a standardized instrument, i.e., the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-III-Revised, Upjohn Version (SCID-UP-R). The results showed higher rates of panic disorder, simple phobia, obsessive-compulsive disorder, major depressive disorder, bipolar disorder and cyclothymia in thyroid patients than in the general population. These findings would suggest that the co-occurrence of psychiatric and thyroid diseases may be the result of common biochemical abnormalities
Socio-demographic and clinical characterization of patients with obsessive-compulsive tic-related disorder (OCTD) : An Italian multicenter study
© Copyright by Pacini Editore SrlIn the DSM-5 a new "tic-related" specifier for obsessive compulsive disorder (OCD) has been introduced, highlighting the importance of an accurate characterization of patients suffering from obsessive-compulsive tic-related disorder ("OCTD"). In order to characterize OCTD from a socio-demographic and clinical perspective, the present multicenter study was carried out. The sample consists of 266 patients, divided in two groups with lifetime diagnoses of OCD and OCTD, respectively. OCTD vs OCD patients showed a significant male prevalence (68.5% vs 48.5%; p < .001), a higher rate of psychiatric comorbidities (69.4 vs 50%; p < .001) - mainly with neurodevelopmental disorders (24 vs 0%; p < .001), a lower education level and professional status (middle school diploma: 25 vs 7.6%; full-Time job 44.4 vs 58%; p < .001). Moreover, OCTD vs OCD patients showed significantly earlier age of OCD and psychiatric comorbidity onsets (16.1 ± 10.8 vs 22.1 ± 9.5 years; p < .001, and 18.3 ± 12.8 vs 25.6 ± 9.4: p < .001, respectively). Patients with OCTD patients were treated mainly with antipsychotic and with a low rate of benzodiazepine (74.2 vs 38.2% and 20.2 vs 31.3%, respectively; p < .001). Finally, OCTD vs OCD patients showed higher rates of partial treatment response (58.1 vs 38%; p < .001), lower rates of current remission (35.5 vs 54.8%; p < .001) and higher rates of suicidal ideation (63.2 vs 41.7%; p < .001) and attempts (28.9 vs 8.3%; p < .001). Patients with OCTD report several unfavorable socio-demographic and clinical characteristics compared to OCD patients without a history of tic. Additional studies on larger sample are needed to further characterize OCTD patients from clinical and therapeutic perspectives.Peer reviewedFinal Published versio
Executive function abnormalities in pathological gamblers
Background: Pathological gambling (PG) is an impulse control disorder characterized by persistent and maladaptive gambling behaviors with disruptive consequences for familial, occupational and social functions. The pathophysiology of PG is still unclear, but it is hypothesized that it might include environmental factors coupled with a genetic vulnerability and dysfunctions of different neurotransmitters and selected brain areas. Our study aimed to evaluate a group of patients suffering from PG by means of some neuropsychological tests in order to explore the brain areas related to the disorder. Methods: Twenty outpatients (15 men, 5 women), with a diagnosis of PG according to DSM-IV criteria, were included in the study and evaluated with a battery of neuropsychological tests: the Wisconsin Card Sorting Test (WCST), the Wechsler Memory Scale revised (WMS-R) and the Verbal Associative Fluency Test (FAS). The results obtained in the patients were compared with normative values of matched healthy control subjects. Results: The PG patients showed alterations at the WCST only, in particular they had a great difficulty in finding alternative methods of problem-solving and showed a decrease, rather than an increase, in efficiency, as they progressed through the consecutive phases of the test. The mean scores of the other tests were within the normal range. Conclusion: Our findings showed that patients affected by PG, in spite of normal intellectual, linguistic and visual-spatial abilities, had abnormalities emerging from the WCST, in particular they could not learn from their mistakes and look for alternative solutions. Our results would seem to confirm an altered functioning of the prefrontal areas which might provoke a sort of cognitive "rigidity" that might predispose to the development of impulsive and/or compulsive behaviors, such as those typical of PG. © 2008 Marazziti et al; licensee BioMed Central Ltd
Effect of Valproate and Antidepressant Drugs on Clozapine Metabolism in Patients With Psychotic Mood Disorders
BACKGROUND:
The aim of the present study was to appraise retrospectively the influence of valproate (VPA) and antidepressants (ADs) on the steady-state plasma concentrations of clozapine (CLZ), the prototype of various second-generation antipsychotics, norclozapine (NCLZ, its main metabolite), and their ratio (NCLZ:CLZ).
METHODS:
Sixty-seven psychotic patients with a prevalent diagnosis of bipolar disorder were studied. We then analyzed data altogether and subdivided them into 4 groups, according to pharmacological treatments: #1 CLZ (n = 21), #2 CLZ plus ADs (n = 13), #3 CLZ plus VPA (n = 16), and #4 CLZ plus ADs plus VPA (n = 17).
RESULTS:
First, significant positive between CLZ and NCLZ plasma levels (in nanograms/milliliter) and the drug daily dosages (in milligrams/kilogram of body weight) (n = 67) were observed (Spearman: rCLZ = 0.49; rNCLZ = 0.61; P < 0.001). We then normalized by given doses CLZ and NCLZ plasma levels, natural log transformed them, and performed analysis of variance factor analyses followed by pairwise comparisons, performed on the 4 groups and the 3 CLZ parameters. We identified significant drug effects on (1) CLZ plasma levels, significantly higher in group #2 versus group #1, and (2) NCLZ:CLZ ratio, lower in group #2 versus groups #1 and #3. Significant drug × gender interactions were observed in group #3, showing higher NCLZ levels and NCLZ:CLZ ratios in men compared with women.
CONCLUSIONS:
Despite its inherent limitations, this observational study confirms the significant increase in plasma CLZ concentrations and reduction in NCLZ:CLZ ratio when this drug was coadministered with ADs (group #2), an effect apparently counteracted by VPA (group #4). The drug × gender interactions in patients taking both CLZ and VPA (group #3) warrant further prospective study
Atm reactivation reverses ataxia telangiectasia phenotypes in vivo
Hereditary deficiencies in DNA damage signaling are invariably associated with cancer predisposition, immunodeficiency, radiation sensitivity, gonadal abnormalities, premature aging, and tissue degeneration. ATM kinase has been established as a central player in DNA double-strand break repair and its deficiency causes ataxia telangiectasia, a rare, multi-system disease with no cure. So ATM represents a highly attractive target for the development of novel types of gene therapy or transplantation strategies. Atm tamoxifen-inducible mouse models were generated to explore whether Atm reconstitution is able to restore Atm function in an Atm-deficient background. Body weight, immunodeficiency, spermatogenesis, and radioresistance were recovered in transgenic mice within 1 month from Atm induction. Notably, life span was doubled after Atm restoration, mice were protected from thymoma and no cerebellar defects were observed. Atm signaling was functional after DNA damage in vivo and in vitro. In summary, we propose a new Atm mouse model to investigate novel therapeutic strategies for ATM activation in ataxia telangiectasia disease
Novel Pharmacological Targets of Post-Traumatic Stress Disorders
Post-traumatic stress disorder (PTSD) is a psychopathological condition with a heteroge-
neous clinical picture that is complex and challenging to treat. Its multifaceted pathophysiology
still remains an unresolved question and certainly contributes to this issue. The pharmacological
treatment of PTSD is mainly empirical and centered on the serotonergic system. Since the therapeutic
response to prescribed drugs targeting single symptoms is generally inconsistent, there is an urgent
need for novel pathogenetic hypotheses, including different mediators and pathways. This paper was
conceived as a narrative review with the aim of debating the current pharmacological treatment of
PTSD and further highlighting prospective targets for future drugs. The authors accessed some of the
main databases of scientific literature available and selected all the papers that fulfilled the purpose of
the present work. The results showed that most of the current pharmacological treatments for PTSD
are symptom-based and show only partial benefits; this largely reflects the limited knowledge of its
neurobiology. Growing, albeit limited, data suggests that the hypothalamic-pituitary-adrenal axis,
opioids, glutamate, cannabinoids, oxytocin, neuropeptide Y, and microRNA may play a role in the
development of PTSD and could be targeted for novel treatments. Indeed, recent research indicates
that examining different pathways might result in the development of novel and more efficient drugs
Serotonin transporter (SERT) and translocator protein (TSPO) expression in the obese ob/ob mouse
Background: An ever growing body of evidences is emerging concerning metabolism hormones, neurotransmitters or stress-related biomarkers as effective modulators of eating behavior and body weight in mammals. The present study sought at examining the density and affinity of two proteins related to neurotransmission and cell metabolism, the serotonin transporter SERT and the cholesterol import-benzodiazepine site TSPO (translocator protein), in a rodent leptin-lacking mutant, the obese ob/ob mouse. Binding studies were thus carried out in brain or peripheral tissues, blood platelets (SERT) and kidneys (TSPO), of ob/ob and WT mice supplied with a standard diet, using the selective radiochemical ligands [(3)H]-paroxetine and [(3)H]-PK11195. Results: We observed comparable SERT number or affinity in brain and platelets of ob/ob and WT mice, whilst a significantly higher [(3)H]-PK11195 density was reported in the brain of ob/ob animals. TSPO binding parameters were similar in the kidneys of all tested mice. By [(3)H]-PK11195 autoradiography of coronal hypothalamic-hippocampal sections, an increased TSPO signal was detected in the dentate gyrus (hippocampus) and choroids plexus of ob/ob mice, without appreciable changes in the cortex or hypothalamic-thalamic regions. Conclusions: These findings show that TSPO expression is up-regulated in cerebral regions of ob/ob leptin-deficient mice, suggesting a role of the translocator protein in leptin-dependent CNS trophism and metabolism. Unchanged SERT in mutant mice is discussed herein in the context of previous literature as the forerunner to a deeper biochemical investigation
