Prevalence and Co-Occurrence of Different Types of Body Dysmorphic Disorder Among Men Having Sex with Men
2020
Body dysmorphic disorder (BDD) is a relatively common psychiatric condition of which the prevalence has not been fully investigated in the non-clinical population, and in particular among men having sex with men (MSM). MSM have proven to be more inclined to develop body dissatisfaction and body image disorders compared to non-MSM. Our study investigates the prevalence of BDD and the prevalence and co-occurrence of muscle dysmorphia (MD) and penile dysmorphic disorder (PDD) in a sample of 261 Italian MSM recruited online. From our data, gathered through self-report measures, the prevalence of BDD, MD, and PDD in our populations was 5.4%, 8.8%, and 4.2%, respectively. Compared to their elders…
Adaptive modes of rumination: the role of subjective anger.
2015
Rumination has been demonstrated to have negative consequences on affect, behaviour, and physiological markers. Recent studies, however, suggest that distinct "modes" of anger-associated rumination may lead to several positive consequences. Previous research primarily used recall procedures of anger episodes to elicit anger. By contrast, the present study focused on the effect of subjective anger on the process of rumination and tested its effects in a "staged" social interaction where a confederate provoked participants. Subsequently, participants engaged in rumination about the anger-eliciting event either in an abstract-distanced or a concrete-immersed rumination mode. Results showed an …
The effects of instrumental reminiscence on resilience and coping in elderly
2014
A B S T R A C T Objectives: Aging, as a stage of development is marked by major changes to which the subject must adapt. Instrumental reminiscence is based on recalling times one coped with stressful circumstances, and analyzing what it took to adapt in those situations. The purpose of the present study was to analyze the effectiveness of an instrumental reminiscent program to enhance adaptive capacity (problemfocused coping and emotion-focused) and resilience in older adults. Method: Thirty participants noninstitutionalized conducted a pre and post assessment on a treatment consisting of the Mini-Mental State Examination (MMSE), Brief Resilient Coping Scale and Stress Coping Questionnaire …
Manifestation and ultrastructural typing of amyloid deposits in the heart
1983
Using light and electron microscopy, 65 cases of amyloid deposits in the heart were examined. Five different groups were distinguished: I. isolated atrial amyloidosis, II. senile cardiac amyloidosis, III. cardiac amyloid accompanying chronic infections and tumors, IV. cardiac amyloid accompanying plasma cell dyscrasia, V. idiopathic cardiac amyloidosis. Seen structurally, no principal differences in the precise localization of the amyloid deposits were found in any of the groups investigated. Amyloid is always deposited in the vicinity of cells with myocytic cell differentiation (i.e. the heart muscle cells, non-striated muscle cells of the vessels), whereby the relevant basement membranes …
Use of Internet in an italian clinical sample
2012
This study is aimed at evaluating Internet use in a psychiatric population. We used the UADI questionnaire to investigate the degree of addictive Internet use in our sample of patients affected by various psychiatric disorders. Several psychological and psychopathological variables related to internet use, have been assessed through the five dimensions of the UADI: dissociation (DIS), Impact on real life (IMP), Experimentation (EXP), Dependence (DEP), Escape (ESC).
Processing of auditory stimuli during tonic and phasic periods of REM sleep as revealed by event-related brain potentials
1996
The brain has been reported to be more preoccupied with dreams during phasic than during tonic REM sleep. Whether these periods also differ in terms of the processing of external stimuli was examined. Event-related brain potentials (ERPs) to a frequent standard tone of 1000 Hz (P = 97%) and infrequent deviant tones of 1100 and 2000 Hz (P = 1.5% for each) were recorded (n = 13) during wakefulness and nocturnal sleep. An ERP wave (called REM-P3) resembling a waking P3 wave was larger for the 2000 Hz deviant during tonic than during phasic REM sleep. Also the P210 wave was larger during tonic than during phasic REM sleep. A reliable mismatch negativity component appeared only in wakefulness. I…
Sensitivity and specificity of the mood disorder questionnaire and the bipolar spectrum diagnostic scale in Argentinean patients with mood disorders
2010
Abstract Objective To assess the sensitivity and specificity of two self-report instruments for detection of bipolarity in a sample of Argentinean patients. Method Spanish versions of the MDQ and the BSDS were administered over four months at 11 sites in Argentina. Diagnoses were made using DSM-IV criteria and the MINI. The study sample consisted of patients diagnosed with Bipolar Disorder (BD) Types I, II, or NOS. BDNOS diagnoses were made using extended guidelines for bipolar spectrum symptoms. Unipolar patients were used as a control group. Of 493 patients screened, 354 completed evaluation by MDQ and MINI, and 363 by BSDS and MINI. Results Specificity of MDQ was 0.97 and BSDS was 0.81. …
Attentional capture by emotional scenes across episodes in bipolar disorder: Evidence from a free-viewing task
2015
We examined whether the initial orienting, subsequent engagement, and overall allocation of attention are determined exogenously (i.e. by the affective valence of the stimulus) or endogenously (i.e. by the participant's mood) in the manic, depressive and euthymic episodes of bipolar disorder (BD). Participants were asked to compare the affective valence of two pictures (happy/threatening/neutral [emotional] vs. neutral [control]) while their eye movements were recorded in a free-viewing task. Results revealed that the initial orienting was exogenously captured by emotional images relative to control images. Importantly, engagement and overall allocation were endogenously captured by threate…
Factors associated with poor functional outcome in bipolar disorder: sociodemographic, clinical, and neurocognitive variables.
2018
Objective: The current investigation aimed at studying the sociodemographic, clinical, and neuropsychological variables related to functional outcome in a sample of euthymic patients with bipolar disorder(BD) presenting moderate-severe levels of functional impairment. Methods: Two-hundred and thirty-nine participants with BD disorders and with Functioning Assessment Short Test(FAST) scores equal or above 18 were administered a clinical and diagnostic interview, and the administration of mood measure scales and a comprehensive neuropsychological battery. Analyses involved preliminary Pearson bivariate correlations to identify sociodemographic and clinical variables associated with the FAST t…
Both rare and de novo copy number variants are prevalent in agenesis of the corpus callosum but not in cerebellar hypoplasia or polymicrogyria.
2013
Agenesis of the corpus callosum (ACC), cerebellar hypoplasia (CBLH), and polymicrogyria (PMG) are severe congenital brain malformations with largely undiscovered causes. We conducted a large-scale chromosomal copy number variation (CNV) discovery effort in 255 ACC, 220 CBLH, and 147 PMG patients, and 2,349 controls. Compared to controls, significantly more ACC, but unexpectedly not CBLH or PMG patients, had rare genic CNVs over one megabase (p = 1.48×10−3; odds ratio [OR] = 3.19; 95% confidence interval [CI] = 1.89–5.39). Rare genic CNVs were those that impacted at least one gene in less than 1% of the combined population of patients and controls. Compared to controls, significantly more AC…
