Chlamydia and Gonorrhea Testing Patterns Among Women with and Without Serious Mental Illness.

Rates of the sexually transmitted infections (STIs) Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) have risen in women by 13% and 40%, respectively, since 2015. Women with Serious Mental Illness (SMI) are at disproportionate risk for STIs. A retrospective chart review was performed at a safety-net healthcare system in the Southeastern United States (US) from 2014 to 2017. CT/GC positivity rates did not differ between the general and SMI populations (6.6% vs. 6.5% for CT and 1.8% vs. 2.2% for GC, respectively). Emergency Medicine accounted for more positive STI test results in SMI patients than the general population (25.2% vs. 19.1% for CT, 47.8% vs. 35.5% for GC, respectively). SMI patients received large portions of STI care in emergency settings, where follow-up is poor. Point of Care (POC) testing could improve care in this setting, and mental healthcare providers must address sexual health with patients who otherwise may not receive this care.

Use of contraception among US women reporting postpartum depressive symptoms, pregnancy risk assessment monitoring system 2009-2011.

OBJECTIVE: We sought to determine the prevalence of postpartum contraceptive use among women with postpartum depressive symptoms (PDS) and examine the association between PDS and contraceptive method. STUDY DESIGN: We evaluated data from 16,357 postpartum women participating in the 2009-2011 Pregnancy Risk Assessment Monitoring System. PDS was defined as an additive score of ≥10 for three questions on depression, hopelessness, and feeling physically slowed. Contraceptive use was categorized as permanent, long-acting reversible contraception (LARC), user-dependent hormonal, and user-dependent non-hormonal. Logistic regression models compared postpartum contraceptive use and method by PDS status. RESULTS: In total, 12.3% of women with a recent live birth reported PDS. Large percentages of women with (69.4%) and without (76.1%) PDS, used user-dependent or no contraceptive method. There were no associations between PDS and use of any postpartum contraception (adjusted Prevalence Ratio (aPR)=1.00, 95% CI 0.98-1.03) or permanent contraception (aPR=1.05, 95% CI 0.88-1.27). LARC use was elevated, but not significantly, among women with PDS compared to those without (aPR=1.16, 95% CI: 1.00-1.34). CONCLUSIONS: Large percentages of women with and without PDS used user-dependent or no contraception. Since depression may be associated with misuse of user-dependent methods, counseling women about how to use methods more effectively, as well as the effectiveness of non-user dependent methods, may be beneficial. IMPLICATIONS: A large percentage of women with PDS are either not using contraception or using less effective user-dependent methods. Since depression may be associated with misuse of user-dependent contraceptive methods, counseling women about how to use methods more effectively, as well as non-user dependent options, such as LARC, may be beneficial.

The benzodiazepine alprazolam dissociates contextual fear from cued fear in humans as assessed by fear-potentiated startle.

BACKGROUND: The startle reflex is potentiated by aversive states. It has been proposed that phasic startle potentiation to a threat cue and sustained startle potentiation to contextual stimuli reflect distinct processes mediated by different brain structures. The present study tested the hypothesis that alprazolam would reduce the sustained startle potentiation to contextual threats but not the startle potentiation to a threat cue. METHODS: Sixteen healthy subjects received each of four treatments: placebo, .5 mg of alprazolam, 1 mg of alprazolam, and 50 mg of diphenhydramine (Benadryl) in a crossover design. Participants were exposed to three conditions, including one in which predictable aversive shocks were signaled by a cue, a second in which shocks were administered unpredictably, and a third condition in which no shocks were anticipated. Acoustic startle were delivered regularly across conditions. RESULTS: Phasic startle potentiation to the threat cue in the predictable condition was not affected by alprazolam. In contrast, the sustained increase in startle in the predictable and unpredictable conditions was reduced significantly by the high dose of alprazolam. CONCLUSIONS: Startle responses to an explicit threat cue and to an aversive context are psychopharmacologically distinct, suggesting that they may represent functionally dissociable aversive states.

Cortisol and DHEA-S are associated with startle potentiation during aversive conditioning in humans.

RATIONALE: Fear conditioning reliably increases the startle reflex and stress hormones, yet very little is known about the effect of stress hormones on fear-potentiated startle. Cortisol and the sulfate ester of dehydroepiandrosterone (DHEA-S) are involved in stress and anxiety. Evidence suggests that low cortisol/DHEA-S ratio has a buffering effect on stress and anxiety in preclinical and clinical studies, suggesting that there may be a relationship between fear-potentiated startle and cortisol and DHEA-S activity. OBJECTIVE: The aim of the study was to examine whether there is a relationship between cortisol/DHEA-S ratio and fear-potentiated startle. METHODS: Thirty healthy subjects participated in a differential aversive conditioning experiment during which one of two stimuli (CS+) was paired with a shock, and the other was not (CS-). Conditioned responses were assessed with the startle reflex, defined as startle potentiation during CS+ compared to CS-. DHEA-S and cortisol levels were assayed from blood samples collected in both a baseline and an aversive conditioning session. Subjective state anxiety, arousal, and valence were assessed at various times during testing. RESULTS: Fear-potentiated startle was larger in individuals with high compared to low cortisol/DHEA-S ratio. Multiple regression analyses revealed that fear-potentiated startle was positively associated with cortisol and negatively associated with DHEA-S. There was no significant correlation between DHEA-S and cortisol levels. CONCLUSION: These data suggest that cortisol and DHEA-S are involved in fear conditioning.

Hydrocortisone impairs hippocampal-dependent trace eyeblink conditioning in post-traumatic stress disorder.

Trace eyeblink conditioning is a hippocampal-dependent associative learning task that could help evaluate hippocampal function in Post-traumatic stress disorder (PTSD). Since preclinical research has demonstrated that trace eyeblink conditioning can be pharmacologically manipulated by glucocorticoids, this task may shed light on glucocorticoid sensitivity in PTSD. This study assessed baseline and hydrocortisone-mediated changes in trace eyeblink conditioning in patients with PTSD and in healthy controls. A total of 12 patients with PTSD and 12 age- and sex-matched healthy controls participated in a trace eyeblink test 6 h following intravenous administration of 30 mg of hydrocortisone. Spontaneous blink rates were similar between PTSD patients and healthy controls. There was no significant difference in the mean conditioned response between PTSD subjects and healthy controls under placebo conditions. Following hydrocortisone administration, only the PTSD patients demonstrated a significant reduction in conditioned response in contrast to healthy subjects who did not demonstrate any change. Patients with PTSD had increased glucocorticoid sensitivity in the focal brain regions mediating trace eyeblink conditioning.
