Disentangling the effects of PTSD from Gulf War Illness in male veterans via a systems-wide analysis of immune cell, cytokine, and symptom measures.

BACKGROUND: One-third of veterans returning from the 1990-1991 Gulf War reported a myriad of symptoms including cognitive dysfunction, skin rashes, musculoskeletal discomfort, and fatigue. This symptom cluster is now referred to as Gulf War Illness (GWI). As the underlying mechanisms of GWI have yet to be fully elucidated, diagnosis and treatment are based on symptomatic presentation. One confounding factor tied to the illness is the high presence of post-traumatic stress disorder (PTSD). Previous research efforts have demonstrated that both GWI and PTSD are associated with immunological dysfunction. As such, this research endeavor aimed to provide insight into the complex relationship between GWI symptoms, cytokine presence, and immune cell populations to pinpoint the impact of PTSD on these measures in GWI. METHODS: Symptom measures were gathered through the Multidimensional fatigue inventory (MFI) and 36-item short form health survey (SF-36) scales and biological measures were obtained through cytokine & cytometry analysis. Subgrouping was conducted using Davidson Trauma Scale scores and the Structured Clinical Interview for Diagnostic and statistical manual of mental disorders (DSM)-5, into GWI with high probability of PTSD symptoms (GWIH) and GWI with low probability of PTSD symptoms (GWIL). Data was analyzed using Analysis of variance (ANOVA) statistical analysis along with correlation graph analysis. We mapped correlations between immune cells and cytokine signaling measures, hormones and GWI symptom measures to identify patterns in regulation between the GWIH, GWIL, and healthy control groups. RESULTS: GWI with comorbid PTSD symptoms resulted in poorer health outcomes compared with both Healthy control (HC) and the GWIL subgroup. Significant differences were found in basophil levels of GWI compared with HC at peak exercise regardless of PTSD symptom comorbidity (ANOVA F = 4.7, P = 0.01,) indicating its potential usage as a biomarker for general GWI from control. While the unique identification of GWI with PTSD symptoms was less clear, the GWIL subgroup was found to be delineated from both GWIH and HC on measures of IL-15 across an exercise challenge (ANOVA F > 3.75, P < 0.03). Additional differences in natural killer (NK) cell numbers and function highlight IL-15 as a potential biomarker of GWI in the absence of PTSD symptoms. CONCLUSION: We conclude that disentangling GWI and PTSD by defining trauma-based subgroups may aid in the identification of unique GWI biosignatures that can help to improve diagnosis and target treatment of GWI more effectively.

Symmetric Breast Surgery: Balancing Procedures versus Prophylactic Mastectomy and Immediate Reconstruction.

BACKGROUND: Various techniques for management of the contralateral breast exist in patients with unilateral breast cancer, including contralateral prophylactic mastectomy with immediate breast reconstruction (PMIBR), and symmetrization techniques including augmentation, reduction, or mastopexy. The purpose of this prospective cohort study was to evaluate and compare complications and patient-reported satisfaction of patients with contralateral PMIBR versus having symmetrization procedures. METHODS: A 7-year, single-institution, prospectively maintained database was reviewed. Patient-reported BREAST-Q scores were obtained at baseline, 3 months, and 12 months prospectively. Postoperative complications, oncologic outcomes, and BREAST-Q scores were compared. RESULTS: A total of 249 patients were included, 93 (37%) of whom underwent contralateral PMIBR and 156 (63%) of whom underwent contralateral symmetrization. The patients who underwent PMIBR were younger and had less comorbidities compared with patients with symmetrization. Rates of major and minor complications were similar, apart from higher rates of minor wound dehiscence in the PMIBR group. When comparing mean change at 12-month follow-up to preoperative results, there was a significant decrease in physical well-being of the chest in the symmetrization compared with the PMIBR group (2.94 versus -5.69; P = 0.042). There were no significant differences in mean breast satisfaction and psychosocial well-being, and nonsignificant decreases in sexual well-being between groups. CONCLUSIONS: Patients with unilateral breast cancer who underwent immediate contralateral breast management, with either contralateral PMIBR or symmetrization techniques, demonstrated similar profiles of major complications and good overall satisfaction except for one physical well-being domain. Management of the contralateral breast with symmetrization may provide similar outcomes compared with PMIBR, which often is considered not necessary in patients without specific indications. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Surgical and patient-reported outcomes following double incision and free nipple grafting for female to male gender affirmation: does obesity make a difference?

BACKGROUND: The efficacy of chest wall contouring in alleviating symptoms of gender dysphoria in transmale and nonbinary patients is well established. As the popularity and indications for these procedures continue to increase, more surgeons are performing these surgeries on obese patients. The aim of this study was to investigate the association of obesity on postoperative and patient-reported outcomes. METHODS: A retrospective chart review was performed for 97 consecutive masculinizing mastectomies by a single surgeon using the double incision and free nipple graft technique (DIFNG). Surgical outcomes were collected using electronic records and patient-reported outcomes using BODY-Q questionnaires. RESULTS: DIFNG mastectomies were performed in 97 patients from 2016 to 2019, of which 43(44%) were obese and 54(56%) were non-obese. The average follow-up time was 62(12 - 112) months in obese patients and 61(10 - 127) months in non-obese patients. There was no difference in minor and major complication rates between non-obese and obese patients [minor: 4(7%) vs 5(12%), p = 0.19) and major: 0(0%) vs 1(2%), p = 0.46]. BODY-Q data was available for 33(77%) of obese and 43(80%) of non-obese patients. There was no difference in scores for each module of the BODY-Q between obese and non-obese patients (p>0.05). CONCLUSION: Chest wall contouring using the DIFNG technique continues to be safe and effective for the management of gender dysphoria in transmale and nonbinary patients. Considering that obese patients have comparable surgical and patient-reported outcomes as non-obese patients, it is our practice to routinely offer the DIFNG technique to healthy obese patients with BMI's between 30 and 40.
