These findings reveal a critical role of CRTC1 in the hippocampus during associative memory, and provide evidence that CRTC1 deregulation underlies memory deficits during neurodegeneration.
We have studied the use of coercive medical measures (forced medication, isolation, and mechanical restraint) in mentally ill inmates within two secure psychiatric hospitals (SPH) and three regular prisons (RP) in Spain. Variables related to adopted coercive measures were analyzed, such as type of measure, causes of indication, opinion of patient inmate, opinion of medical staff, and more frequent morbidity. A total of 209 patients (108 from SPH and 101 from RP) were studied. Isolation (41.35%) was the most frequent coercive measure, followed by mechanical restraint (33.17%) and forced medication (25.48%). The type of center has some influence; specifically in RP there is less risk of isolation and restraint than in SPH. Not having had any previous imprisonment reduces isolation and restraint risk while increases the risk of forced medication, as well as previous admissions to psychiatric inpatient units does. Finally, the fact of having lived with a partner before imprisonment reduces the risk of forced medication and communication with the family decreases the risk of isolation. Patients subjected to a coercive measure exhibited a pronounced psychopathology and most of them had been subjected to such measures on previous occasions. The mere fact of external assessment of compliance with human rights slows down the incidence of coercive measures.
Statement of the problem : Stressful life events have been shown to have great influence on the onset or recurrence of psychotic symptoms [1]. Increased stressful life events [2], perceived stress [3], and higher cortisol levels [4,5] have been described in subjects with a first psychotic episode. The main aim of our study was to explore the relationship between stress measures and cortisol levels in subjects with early psychoses. Methods : We included 85 subjects, aged between 18 and 35 years, who attended the Early Psychosis Program from Reus (Tarragona, Spain). All subjects were assessed at baseline using a structured clinical interview (Schedules for Clinical Assessment in Neuropsychiatry) to obtain a clinical diagnosis. We stratified the sample into three groups: Group 1, first episode of psychosis (FEP, N = 36); Group 2, critical period (CP, defined as a psychotic disorder >1 year of duration of illness, N=35); and Group 3, ultra high risk (UHR, subjects with prodromal psychotic symptoms, N=14). Perceived stress was assessed with perceived stress scale (PSS). Stressful life events during the previous 6 months were assessed with the Holmes Rahe Social Readjustment Scale. A fasting morning blood sample (9 h) was obtained to determine total cortisol in plasma. SPSS v.17.0 was used for the statistical analyses. Spearman correlations were used to explore the association between continuous variables. Wilcoxon test was used to compare continuous variables between diagnostic groups. A p-value <0.05 was considered significant. Results : In all subjects, stressful life events were positively associated with perceived stress (r=0.244, p=0.033) but not with plasma cortisol levels. In the stratified analysis by diagnoses, no significant differences in stressful life events were found between all three groups. Subjects at risk for psychosis (UHR) reported greater scores in PSS (30.6±11.7) than other groups (FEP: 27.0±0.1; CP: 20.9), this result being statistically significant (p=0.003). Those subjects from the critical period group showed increased plasma cortisol (20.7±4.8) when compared to UHR (18.9±6.4) and FEP (18.12±4.5) groups. Conclusion : UHR subjects report greater levels of perceived stress when compared to those subjects with a psychotic disorder. Stressful life events and perceived stress are associated but not with plasma cortisol levels
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
