Introduction: In May 2014, the US Department of Health and Human Services prohibited insurance discrimination of transgender individuals. Despite this, insurance plans often lack explicit guidelines on gender transition-related care and coverage of surgical procedures is extremely varied. We evaluated the evolution of insurance coverage of gender-affirming care following the 2014 legislative change., Methods: Insurance providers were selected based on company market share. We conducted a Web-based search and telephone interviews to identify the corresponding policies related to gender-affirming health care. We compared policy changes made before and after the 2014 US Department of Health and Human Services decision., Results: Of the 92 insurers surveyed, 7% did not have a policy, and 315 policy revisions were documented. After the legislation, a significantly higher proportion of policy revisions were related to coverage of services (36% vs 11%, P < 0.0001), removal of existing criteria significantly decreased (23% vs 49%, P = 0.0044), and addition of criteria unrelated to international standards sharply increased (32% vs 2%, P = 0.0002). This resulted in reduced coverage of facial feminization, hair transplantation, laryngochondroplasty, and voice modification surgery. However, nipple reconstruction experienced increased coverage. The percentage of revisions to add preauthorization criteria to meet international standards (49% vs 45%, P = 0.6714) or to change terminology (37% vs 27%, P = 0.1055) were similar before and after the legislation., Conclusions: After the transformative legislation in 2014, an increasing number of insurance companies established gender transition-related policies. As more patients seek gender-affirming care, insurers deviate from international guidelines and create additional benchmarks that may act as barriers to care., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background: In microvascular breast reconstruction, the internal mammary and thoracodorsal vessels are commonly used recipients. However, these vessels are sometimes compromised or unavailable. We hypothesize that a transverse infraclavicular (TIC) incision may provide efficient and reliable exposure to perform free flap anastomosis to the thoracoacromial (TAC) vessels for breast reconstruction., Methods: The authors present their results from a cadaveric feasibility study and a retrospective case series of 4 consecutive breast reconstruction patients in which the TIC-TAC approach was used., Results: The cadaveric dissection demonstrated a 5.5-cm pedicle length and a 3.75-mm diameter on the left side. On the right, the pedicle measured 5 cm in length and 4 mm in diameter. The dissection time was 10 minutes on the left side and 13 minutes on the right side. Five free flap breast reconstructions were performed in 4 patients using the TIC approach to the TAC artery which served as the primary recipient. The average pedicle length was 6.25 cm with a diameter of 3.55 mm. The pedicle was isolated and delivered through the infraclavicular incision in an average of 16.3 minutes on the left (n = 2) and 12.6 minutes on the right (n = 3). There were no complications, such as flap compromise or reoperation., Conclusions: The TIC-TAC approach is feasible for microvascular breast reconstruction and can be considered for use by microvascular breast surgeons.

Clinical detection of free flap failure lacks sensitivity. Failure is likely accompanied by altered gene expression; however, a genomic approach that identifies potential biomarkers and therapeutic targets has not been described. This study identifies genetic RNA expression alterations via microarray in a free flap failure animal model. A free tissue transfer rat model based on the inferior epigastric vessels was utilized. After microscopic anastomosis, the vein was occluded and RNA extracted from flap tissue of failure and control groups. Gene expression of 3 experimental and control group samples was assessed with the Affymetrix GeneChip Rat 230 v2.0 microarray. Quantitative reverse transcription polymerase chain reaction was performed on RNA of genes identified on an additional 6 experimental and 7 control group flaps. Eight hundred ninety of 28,000 genes had greater than 2-fold expression differences between experimental and controls. Student t test and 2-way analysis of variance filtering with equal variance identified 53 genes with statistically significant differences. Hierarchical clustering by gene ontology identified 4 genes with likely involvement in failure pathogenesis: RT1 class II, locus Bb, secreted frizzled-related protein 1, platelet/endothelial cell adhesion molecule, and Claudin 5. Validation performed by quantitative reverse transcription polymerase chain reaction revealed statistically significant expression alterations in locus Bb, platelet/endothelial cell adhesion molecule, and Claudin 5 of the failure group. Utilizing expression thresholds for test positivity, venous occlusion was predicted with 100% sensitivity and 86% specificity. Three highly sensitive and specific novel genes predictive of flap failure from venous occlusion were identified with altered expression in an animal model.

Repair of large complex abdominal hernias with significant loss of domain requires component separation in combination with either a synthetic or biologic interpositional material. We previously described an algorithm for complex abdominal hernia repair, which incorporates Alloderm as an interpositional material and selective use of prolene mesh as an overlay. We now report recurrent laxity in a series of patients who were repaired with interpositional Alloderm alone without prolene mesh overlay. We reviewed all patients who underwent repair of massive ventral hernias and identified 7 patients who presented with abdominal wall laxity following component separation with interpositional Alloderm alone. All patients developed laxity within 12 months and required a secondary procedure. At the time of re-exploration, severe attenuation in the Alloderm was noted. The segment was excised, the edges closed primarily, and prolene mesh was placed as an onlay. Although Alloderm has been reported to be an effective biologic material for abdominal hernia reconstruction, we have noted significant laxity requiring secondary intervention.
