Open Trial of Trauma-Focused Psychodynamic Psychotherapy for Posttraumatic Stress Disorder Among LGBTQ Individuals.

OBJECTIVE: Lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals report higher rates of exposure to traumatic events and posttraumatic stress disorder (PTSD) compared with heterosexual and cisgender individuals. No treatment outcomes research has focused on PTSD in the LGBTQ population. Trauma-focused psychodynamic psychotherapy (TFPP) is a brief, manualized, attachment- and affect-focused psychotherapy for PTSD. TFPP explicitly incorporates broad identity-related and societal factors into its conceptualization of trauma and its consequences, which may be especially helpful for LGBTQ patients with minority stress who seek affirmative care. METHODS: Fourteen LGBTQ patients with PTSD, assessed with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), received 24 sessions of twice-weekly (12 weeks) TFPP via teletherapy provided by supervised early-career therapists inexperienced in the modality. Sessions were videotaped to monitor therapists' treatment adherence. Patients were assessed at baseline, week 5, termination (week 12), and 3 months posttreatment for PTSD symptoms (assessed with the CAPS-5) and secondary outcomes. RESULTS: TFPP was well tolerated by patients, with 12 (86%) completing the intervention. CAPS-5-measured PTSD symptoms, including dissociation, significantly improved during treatment (mean decrease=-21.8, d=-1.98), and treatment gains were maintained at follow-up. Most patients experienced PTSD clinical response (N=10, 71%) or diagnostic remission (N=7, 50%). Patients generally experienced significant, concomitant improvements in complex PTSD symptoms, general anxiety, depression, and psychosocial functioning. Adherence to the intervention among therapists was high, with 93% of rated sessions meeting adherence standards. CONCLUSIONS: TFPP shows promise in the treatment of PTSD among sexual and gender minority patients seeking LGBTQ-affirmative PTSD care.

Intravenous Ketamine Exacerbating Symptoms of Acute Stress Disorder: A Case Report and Systematized Review of Existing Literature.

BACKGROUND: Ketamine is an anesthetic and analgesic known for its psychotomimetic properties, such as dissociation and altered perception. Acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) are characterized by unwanted memories, intrusive thoughts, and dissociative flashbacks following an acute traumatic event. It is unknown how analgesic ketamine affects the symptomatology of ASD when administered to patients in the posttraumatic period. OBJECTIVE AND METHODS: In this article, we present the case of a 26-year-old man who sustained gunshot wounds and developed worsened ASD after receiving analgesic ketamine. We also present a review of the current literature on peritraumatic ketamine and its subsequent effect on ASD and PTSD. RESULTS: In 2 out of 3 articles examining ketamine and ASD, ketamine was associated with worsened symptomatology of ASD. There were 6 articles examining ketamine and PTSD. In 1 of 6 articles, ketamine was associated with increased incidence and/or severity of PTSD, and in 2 of 6, it was associated with decreased incidence and/or severity of PTSD. There was no relationship between ketamine and subsequent PTSD in 3 of 6 articles. CONCLUSION: We conclude that ketamine's psychotomimetic properties may exacerbate the dissociative and perceptual symptoms of ASD, but its long-term effects on PTSD are still unclear. In patients with preexisting ASD, the potential risks and benefits of using analgesic ketamine must be weighed carefully.

Omission and Commission in Morally Injurious Experiences Among COVID-19 Health Care Professionals.

Objective: To produce a qualitative description of the impact of moral injury on medical providers during the COVID-19 pandemic.Methods: A convergent mixed-methods study design was used to explore experiences of health care workers during the first 12 months of the COVID-19 pandemic. Participants completed the Moral Injury Symptom Scale-HP (MISS-HP) and a 60-minute interview, in which they described their work experiences from March 2020 through January 2021. The study was conducted between May 2021 and August 2021.Results: Eight physicians and 6 nurses were interviewed. Most participants (71%) worked in the emergency department, while 29% worked in the medical intensive care unit (MICU). MISS-HP scores were 49 on average and ranged from 29 to 73. Among the demographic groups, MICU participants scored the highest (56) and men scored the lowest (40). There were no significant differences in scores between any demographic group. The analysis of interview data showed how omissions and commissions in one's professional duties created internal conflicts, which were inextricably linked to a deeper sense of feelings of guilt and blame around experiences of betraying or being betrayed and an inability to uphold one's moral values.Conclusions: The pandemic upended a previously reliable and imperceptible experience of a background of safety, in which the provision of both material resources and human presence was expected without question. Future directions generated from this study might examine the role of dependency on leadership structures and relationships with self and others that create the conditions for moral injury.Prim Care Companion CNS Disord 2024;26(1):23m03651.

Obesity promotes breast epithelium DNA damage in women carrying a germline mutation in BRCA1 or BRCA2.

Obesity, defined as a body mass index (BMI) ≥ 30, is an established risk factor for breast cancer among women in the general population after menopause. Whether elevated BMI is a risk factor for women with a germline mutation in BRCA1 or BRCA2 is less clear because of inconsistent findings from epidemiological studies and a lack of mechanistic studies in this population. Here, we show that DNA damage in normal breast epithelia of women carrying a BRCA mutation is positively correlated with BMI and with biomarkers of metabolic dysfunction. In addition, RNA sequencing showed obesity-associated alterations to the breast adipose microenvironment of BRCA mutation carriers, including activation of estrogen biosynthesis, which affected neighboring breast epithelial cells. In breast tissue explants cultured from women carrying a BRCA mutation, we found that blockade of estrogen biosynthesis or estrogen receptor activity decreased DNA damage. Additional obesity-associated factors, including leptin and insulin, increased DNA damage in human BRCA heterozygous epithelial cells, and inhibiting the signaling of these factors with a leptin-neutralizing antibody or PI3K inhibitor, respectively, decreased DNA damage. Furthermore, we show that increased adiposity was associated with mammary gland DNA damage and increased penetrance of mammary tumors in Brca1+/- mice. Overall, our results provide mechanistic evidence in support of a link between elevated BMI and breast cancer development in BRCA mutation carriers. This suggests that maintaining a lower body weight or pharmacologically targeting estrogen or metabolic dysfunction may reduce the risk of breast cancer in this population.
