Polyvictimization and Psychiatric Sequelae Associated with Female Genital Mutilation/Cutting (FGM/C)

Female Genital mutilation/cutting (FGM/C) is associated with enduring psychiatric complications. In this study, we investigate the rates of co-morbid abuses and polyvictimization experienced by survivors of FGM/C. This is a sub-analysis of a cohort study examining the patient population at the EMPOWER Center for Survivors of Sex Trafficking and Sexual Violence in New York City. A retrospective chart-review of electronic medical records was conducted for all consenting adult patients who had FGM/C and had an intake visit between January 16, 2014 and March 6, 2020. Of the 80 participants, ages ranged from 20 to 62 years with a mean of 37.4 (SD?=?9.1) years. In addition to FGM/C, participants were victims of physical abuse (43; 53.8%), emotional abuse (35; 43.8%), sexual abuse (35; 43.8%), forced marriage (20; 25%), child marriage (13; 16.3%), and sex trafficking (1; 1.4%). There was a high degree of polyvictimization, with 41 (51.2%) experiencing 3 or more of the aforementioned abuses. Having FGM/C on or after age 13 or having a higher total abuse score was also found to be strong predictors of depression and PTSD. The high rates of polyvictimization among survivors of FGM/C are associated with development of depression and PTSD. Despite co-morbid abuses, patients still attribute substantial psychiatric symptoms to their FGM/C. Health care providers should understand the high risk of polyvictimization when caring for this patient population.

     

Intervention for arch obstruction after the Norwood procedure: Prevalence,associated factors,and practice variability

Objective

Arch obstruction after the Norwood procedure is common and contributes to mortality. We determined the prevalence, associated factors, and practice variability of arch reintervention and assessed whether arch reintervention is associated with mortality.

The MMPI and premenstrual syndrome: profile fluctuations between best and worst times during the menstrual cycle

The MMPI was administered during the patient-perceived best time of the menstrual cycle and during the patient-perceived worst time of the cycle in order to examine the stability of MMPI profile configurations. Subjects were 214 women who were referred to two metropolitan outpatient premenstrual syndrome (PMS) clinics for moderate to severe premenstrual complaints. This sample was selected from 1,849 intake files after screening by strict selection criteria for PMS. The results indicate that there are wide fluctuations in profile patterns between the best and worst times of the menstrual cycle for a large number of patients. Caution in using the MMPI is strongly advised.     

Pertussis toxin inhibits alpha 2-adrenoceptor-mediated inhibition of adenylate cyclase without affecting muscarinic regulation of [Ca2+]i or inositol phosphate generation in SH-SY5Y human neuroblastoma cells

The present study reports the differential effects of pertussis toxin on muscarinic regulation of intracellular Ca2+ and inositol phosphate generation and alpha 2-adrenoceptor-mediated inhibition of cAMP formation in SH-SY5Y human neuroblastoma cells. Carbachol caused a biphasic increase in intracellular Ca2+ (release of internal stores and Ca2+ entry) and a dose-dependent increase in inositol phosphate formation. Pertussis toxin pretreatment did not affect either of these components of the signal transduction pathway but did completely reverse the alpha 2-adrenoceptor-mediated inhibition of forskolin-stimulated cAMP formation. These data indicate that muscarinic regulation of inositol phosphate generation occurs via a pertussis toxin-insensitive G-protein and that Ca2+ entry in these cells may not occur via a G-protein.     

The First‐Episode Psychosis Outcome Study: premorbid and baseline characteristics of an epidemiological cohort of 661 first‐episode psychosis patients

Aims: Studies conducted in first‐episode psychosis (FEP) samples avoid many biases. However, very few studies are based on epidemiological cohorts treated in specialized FEP services. The aim of this file audit study was to examine premorbid and baseline characteristics of a large epidemiological sample of FEP. Methods: File audit study of all patients admitted to the Early Psychosis Prevention and Intervention Centre between 1998 and 2000 using a specialized questionnaire. Results: There were 661 patient files included in the study. Premorbid evaluation revealed high rates of substance use disorder (74.1%), history of psychiatric disorder (47.5%), past traumatic events (82.7%) suicide attempts (14.3%) and family history of psychiatric illness (55.6%). Baseline characteristics revealed high intensity of illness (mean CGI 5.5), high prevalence of lack of insight (62%) and high rate of comorbidity (70%). Conclusion: High rates of traumatic events or episodes of mental illness before treatment for FEP must be considered when designing treatment approaches because a too narrow focus on positive psychotic symptoms will inevitably lead to incomplete treatment. Additionally, early intervention programmes need sufficient range of resources to address the multiple challenges presented by FEP patients such as high severity of illness, comorbidities and functional impairment. Finally, observation of an important degree of functional impairment despite short duration of untreated psychosis suggests that while early detection of FEP is a necessary step in early intervention, it may not be sufficient to improve functional recovery in psychosis and that efforts aimed at identifying people during the prodromal phase of psychotic disorders should be pursued.     

Baclofen-induced disinhibition in area CA1 of rat hippocampus is resistant to extracellular Ba

The mechanism of disinhibition produced by (±)-baclofen was studied using intracellular recording in area CA1 of rat hippocampal slices. Baclofen reversibly depressed monosynaptic IPSPs evoked by direct activation of interneurons in the presence of the excitatory amino acid receptor antagonists 6,7-dinitroquinoxaline-2,3-dione (DNQX) andd,l-2amino-5-phosphonovalerate (APV). Ba²⁺ prevented baclofen-induced hyperpolarization of pyramidal neurons but not depression of monosynaptic IPSPs by baclofen. Baclofen reversibly depressed monosynaptic IPSPs when applied close to the recording site, but was ineffective when applied close to the stimulating site in stratum radiatum. These results suggest that baclofen disinhibits pyramidal neurons in area CA1 of the rat hippocampus by activating receptors on the terminals of inhibitory neurons that are coupled to a Ba²⁺-insensitive effector mechanism.
