BACKGROUND: Evidence suggests that prenatal insult may play a role in the etiology of psychotic disorders. Minor physical anomalies (MPA) are an indicator of abnormal fetal development and are elevated in individuals at genetic and behavioral risk for psychosis. Yet, there has been little empirical research on the relationships between MPAs and other neurobiological risk indicators. We hypothesized that the frequency of MPAs (an external marker of prenatal central nervous system [CNS] disruption) would be associated with two other biomarkers suggestive of disruptions in fetal neurodevelopment: movement abnormalities (an indicator of striatal abnormalities) and heightened cortisol secretion (an indicator of hypothalamic-pituitary-adrenal [HPA]/hippocampal function). METHODS: Participants with schizotypal personality disorder (SPD; n = 39) and both normal (n = 47) and other personality disorders (n = 28) control subjects were administered structured diagnostic interviews and assessed for MPAs, movement abnormalities, and salivary cortisol. RESULTS: Schizotypal personality disorder participants showed significantly greater MPAs and movement abnormalities and higher cortisol than both the normal and other personality disorders groups. Hierarchical linear regression analyses revealed that higher rates of MPAs were linked with greater movement abnormalities and salivary cortisol. CONCLUSIONS: The findings suggest that MPAs serve as a marker of neurodevelopmental abnormalities that affect striatal and hippocampal regions. 相似文献

Background and objectivesResearch suggests a relationship between intolerance of uncertainty (IU) and obsessive-compulsive disorder (OCD), though this has been limited to self-report measures of OCD symptoms. The current investigation examined the relationship between IU and multiple symptom domains of OCD using self-report and in vivo assessments of OC symptoms.MethodsFive separate studies are presented in which undergraduate students (N = 603) were administered a self-report measure of IU and tasks related to either ordering and arranging, checking, washing, contamination avoidance, or neutralization.ResultsIntolerance of uncertainty was found to be significantly related to each self-report measure of the OCD symptom domains (ps < .01). Further, IU was predictive of performance on all in vivo tasks (ps < .05) except one concerning neutralizing/harm-related obsessions.LimitationsThis study relied on an unselected sample and was correlational in design.ConclusionsThe current study demonstrates that IU is related to multiple OC symptom dimensions. Future experimental research is warranted to evaluate the causal role of IU in OCD. 相似文献

The development of a group A streptococcal (GAS) vaccine has focused on the M protein, a major virulence factor. Antibodies against the amino terminal domain of the M protein are generally protective but only provide type-specific immunity. J14, a 29-mer peptide sequence which contains a conserved epitope from the C-repeat region of the M protein, offers the possibility of a vaccine which will elicit protective opsonic antibodies against multiple GAS strains. In this study we have shown that antibodies raised against J14 are capable of opsonising 37 GAS isolates representing different emm types derived from a region in which GAS infection is endemic. We also demonstrate that J14 antisera is capable of opsonising GAS isolates containing J14 homologues but not J14-specific sequences, further increasing the strain coverage of this vaccine candidate. Isolates with three C-repeats were opsonised more efficiently than isolates with two repeats. Opsonisation of a strain with only a single C-repeat was dramatically lower than other strains tested. The number of C-repeats present in the M protein of individual isolates therefore appears to be the critical factor in determining bactericidal capacity of J14 antisera. The reduced opsonic capacity of sera against this strain was shown to correlate with a reduced capacity to bind J14 antisera, as demonstrated by immunofluorescence microscopy and FACS analysis. In vivo challenge experiments also confirmed the protective efficacy of immunisation with J14 peptide. 相似文献

Purpose: To report the HLA profile of VKH patients from India. Method: Forty-one patients and 50 controls were studied. Phenotyping using a lymphocytotoxicity assay was done for HLA-A and -B. DNA-based sequence-specific low resolution typing was done for HLA-DR and -DQ loci. Results: HLA-A9 was over-represented in the patient population (p = 0.01), whereas HLA-A11 (p = 0.03) and HLA-DRB1*13 (p = 0.007) were found to be underrepresented. The frequency of HLA-DRB1*04 was 14.6% and 10% in the patient population and controls, respectively. The HLA-DQ frequencies did not differ significantly between patients and controls. Conclusion: Unlike that reported in most populations, we did not find a significant association between HLA-DRB1*04 and our patient population. 相似文献

ObjectivesThis study aimed to identify the prevalence and risk factors for occupational burnout in community pharmacists.MethodsCommunity pharmacists were solicited through a professional network e-mail Listserv to complete an anonymous, electronic survey on burnout. The survey included the Maslach Burnout Inventory–Human Services Survey (MBI-HSS) and a work-factors–based questionnaire. The MBI-HSS assessed burnout on the basis of feelings of emotional exhaustion, depersonalization, and reduced personal accomplishment. The additional questionnaire was used to evaluate risk factors for burnout by collecting information on pharmacist demographics, position characteristics, and pharmacy store characteristics. Logistic regression was performed to identify the risk factors associated with burnout.ResultsA total of 412 community pharmacists responded to the survey (7.4% response rate), of whom 411 were included in the final analysis. Overall, 308 (74.9%) of responding community pharmacists experienced burnout in at least 1 of the 3 subscales of the MBI-HSS. Most of the pharmacists experienced burnout owing to emotional exhaustion (68.9%), followed by depersonalization (50.4%) and reduced personal accomplishment (30.7%). The significant risk factors for burnout included shorter years of experience, practicing primarily in a chain pharmacy, and a lack of resources for burnout or resiliency.ConclusionThere is a high degree of burnout in community pharmacists (74.9%). Future research is warranted to examine optimal strategies to prevent burnout and promote resiliency in the profession. 相似文献
