A Scoping Review of Quality-of-Life Assessments Employed in Abdominal Wall Reconstruction

INTRODUCTION

Surgeons use several quality-of-life instruments to track outcomes following abdominal wall reconstruction (AWR); however, there is no universally agreed upon instrument. We review the instruments used in AWR and report their utilization trends within the literature.

METHODS

This scoping review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for Scoping Reviews guidelines using the PubMed, Embase, Web of Science, ClinicalTrials.gov, and Cochrane databases. All published articles in the English language that employed a quality-of-life assessment for abdominal wall hernia repair were included. Studies which focused solely on aesthetic abdominoplasty, autologous breast reconstruction, rectus diastasis, pediatric patients, inguinal hernia, or femoral hernias were excluded.

RESULTS

Six hernia-specific tools and six generic health tools were identified. The Hernia-Related Quality-of-Life Survey and Carolinas Comfort Scale are the most common hernia-specific tools, while the Short-Form 36 (SF-36) is the most common generic health tool. Notably, the SF-36 is also the most widely used tool for AWR outcomes overall. Each tool captures a unique set of patient outcomes which ranges from abdominal wall functionality to mental health.

CONCLUSIONS

The outcomes of AWR have been widely studied with several different assessments proposed and used over the past few decades. These instruments allow for patient assessment of pain, quality of life, functional status, and mental health. Commonly used tools include the Hernia-Related Quality-of-Life Survey, Carolinas Comfort Scale, and SF-36. Due to the large heterogeneity of available instruments, future work may seek to determine or develop a standardized instrument for characterizing AWR outcomes.

United States Health Policies on Gender-Affirming Care in 2022

BACKGROUND

Within the United States, access to gender-affirming operations covered by health insurance has increased dramatically over the past decade. However, the perpetually changing landscape and inconsistencies of individual state health policies governing private and public insurance coverage present a lack of clarity for reconstructive surgeons and other physicians attempting to provide gender-affirming care. This work systematically reviewed the current U.S. health policies for both private insurance and Medicaid on a state-by-state basis.

METHODS

Individual state health policies in effect as of August of 2022 on gender-affirming care were reviewed using the LexisNexis legal database, state legislature publications, and Medicaid manuals. Primary outcomes were categorization of policies as protective, restrictive, or unclear for each state. Secondary outcomes included analyses of demographics covered by current health policies and geographic differences.

RESULTS

Protective state-level health policies related to gender-affirming care were present in approximately half of the nation for both private insurance (49.0%) and Medicaid (52.9%). Explicitly restrictive policies were found in 5.9% and 17.6% of states for private insurance and Medicaid, respectively. Regionally, the Northeast and West had the highest rates of protective policies, whereas the Midwest and South had the highest rates of restrictive policies on gender-affirming care.

CONCLUSIONS

State-level health policies on gender-affirming care vary significantly across the United States with regional associations. Clarity in the current and evolving state-specific health policies governing gender-affirming care is essential for surgeons and physicians caring for transgender and gender-diverse individuals.

Long-term outcomes of sphincter pharyngoplasty in patients with cleft palate

OBJECTIVE

The purpose of this study was to evaluate long-term outcomes of sphincter pharyngoplasties, including speech outcomes, revision surgeries, and postoperative incidence of obstructive sleep apnea (OSA).

DESIGN

Retrospective matched-cohort study SETTING: Two craniofacial centers in Los Angeles, CA PATIENTS: Patients (n = 166) with cleft lip and palate (CLP) or isolated cleft palate (iCP) who underwent sphincter pharyngoplasty from 1992 to 2022 were identified. An age- and diagnosis-matched control group of 67 patients with CLP/iCP without velopharyngeal insufficiency (VPI) was also identified.

INTERVENTIONS

The pharyngoplasty group underwent sphincter pharyngoplasty, whereas the non-VPI group had no history of VPI surgery or sphincter pharyngoplasty.

MAIN OUTCOME MEASURES

Postoperative speech outcomes, revision surgeries, and incidence of OSA were evaluated. Multivariable regression was used to evaluate independent predictors of OSA.

RESULTS

Among the patients in the pharyngoplasty cohort, 63.9% demonstrated improved and sustained speech outcomes after a single pharyngoplasty, with a median postoperative follow-up of 8.8 years (interquartile range [IQR], 3.6-12.0 years). One-third of the patients who underwent pharyngoplasty required a revision surgery, with a median time to primary revision of 3.9 years (IQR, 1.9-7.0 years). OSA rates increased significantly among the pharyngoplasty cohort, from 3% before surgery to 14.5% after surgery (p < 0.001). The average time from sphincter pharyngoplasty to OSA diagnosis was 4.4 ± 2.4 years. Multivariable analysis results indicated that sphincter pharyngoplasty surgery was independently associated with a fourfold increase in OSA (p = 0.03).

CONCLUSIONS

Although sphincter pharyngoplasty remains successful in improving long-term speech outcomes, persistent OSA is a sequela that should be monitored beyond the immediate postoperative period.

Duration of Feminizing Hormone Therapy on Facial Fat Volumes

BACKGROUND

Gender-affirming feminizing hormone therapy induces body fat redistribution. However, the amount and timing of facial fat changes in response to feminizing hormone therapy are unknown, albeit relevant to counseling and surgical planning for facial gender-affirming surgery. In this work, we assessed the influence of feminizing hormone therapy duration on malar and temporal fat volume.

METHODS

Malar and temporal fat volumes were compared using computed tomography in transfeminine patients (age 20-29 years, body mass index [BMI] 18.5-24.9) treated with feminizing hormone therapy for <2 years versus ≥2 years. Patients with prior surgical or non-surgical facial soft-tissue interventions were excluded. Multivariable linear regressions evaluated the contribution of hormone therapy duration to malar and temporal fat volumes.

RESULTS

45 patients were included with 30 patients (66.7%) treated with feminizing hormone therapy for ≥2 years and 15 patients (33.3%) treated for <2 years (median[interquartile range, IQR]: 44.5[33.5-65.6] vs. 15.0[11.0-18.0] months, p<0.001). Patients treated with hormone therapy for ≥2 years demonstrated a 1.6-fold greater malar fat volume (5.5[4.2-6.3] vs. 3.4[2.3-4.2] cm 3,p<0.001) and 1.4-fold greater temporal fat volume (2.8[2.4-3.6] cm 3 vs. 2.0[1.7-2.4] cm 3, p=0.01) compared to those treated for <2 years. When accounting for other contributory variables such as BMI, skull size, and total soft-tissue depth in multivariable linear regression models, hormone therapy duration ≥2 years independently predicted higher malar (β=0.51, p<0.001) and temporal (β=0.32, p=0.02) fat volumes.

CONCLUSIONS

Feminizing hormone therapy increases malar and temporal fat volumes by approximately 2 cm 3 and 0.8 cm 3 for each area, respectively, after 2 years of treatment.

Association of Parental Status and Gender With Burden of Multidisciplinary Tumor Boards Among Oncology Physicians

Importance

Tumor boards are integral to the care of patients with cancer. However, data investigating the burden of tumor boards on physicians are limited.

Objective

To investigate what physician-related and tumor board-related factors are associated with higher tumor board burden among oncology physicians.

Design, Setting, and Participants

Tumor board burden was assessed by a cross-sectional convenience survey posted on social media and by email to Cedars-Sinai Medical Center cancer physicians between March 3 and April 3, 2022. Tumor board start times were independently collected by email from 22 top cancer centers.

Main Outcomes and Measures

Tumor board burden was measured on a 4-point scale (1, not at all burdensome; 2, slightly burdensome; 3, moderately burdensome; and 4, very burdensome). Univariable and multivariable probabilistic index (PI) models were performed.

Results

Surveys were completed by 111 physicians (median age, 42 years [IQR, 36-50 years]; 58 women [52.3%]; 60 non-Hispanic White [54.1%]). On multivariable analysis, factors associated with higher probability of tumor board burden included radiology or pathology specialty (PI, 0.68; 95% CI, 0.54-0.79; P = .02), attending 3 or more hours per week of tumor boards (PI, 0.68; 95% CI, 0.58-0.76; P < .001), and having 2 or more children (PI, 0.65; 95% CI, 0.52-0.77; P = .03). Early or late tumor boards (before 8 am or at 5 pm or after) were considered very burdensome by 33 respondents (29.7%). Parents frequently reported a negative burden on childcare (43 of 77 [55.8%]) and family dynamics (49 of 77 [63.6%]). On multivariable analysis, a higher level of burden from early or late tumor boards was independently associated with identifying as a woman (PI, 0.69; 95% CI, 0.57-0.78; P = .003) and having children (PI, 0.75; 95% CI, 0.62-0.84; P < .001). Independent assessment of 358 tumor boards from 22 institutions revealed the most common start time was before 8 am (88 [24.6%]).

Conclusions and Relevance

This survey study of tumor board burden suggests that identifying as a woman or parent was independently associated with a higher level of burden from early or late tumor boards. The burden of early or late tumor boards on childcare and family dynamics was commonly reported by parents. Having 2 or more children, attending 3 or more hours per week of tumor boards, and radiology or pathology specialty were associated with a significantly higher tumor board burden overall. Future strategies should aim to decrease the disparate burden on parents and women.

Association of Parental Status and Gender with Burden of Multidisciplinary Tumor Boards

PURPOSE/OBJECTIVE(S)

Tumor boards are an integral part of the management of patients with cancer. However, there is limited data investigating the burden of tumor boards on physicians. Our objective was to determine what physician-related, and tumor board-related factors associate with higher burden.

MATERIALS/METHODS

Tumor board start times were collected by email from 22 National Cancer Institute-designated cancer centers and/or U.S. World and News Report Top 40 hospitals for cancer. Tumor board burden was assessed by a cross-sectional convenience survey posted on social media and by email to Cedars-Sinai Medical Center cancer physicians between March 3, 2022, and April 3, 2022. Tumor board burden was measured on a 4-point scale (1, not at all; 2, slightly; 3, moderately; 4, very burdensome). Univariable and multivariable analyses were performed using a probabilistic index model.

RESULTS

The timing of 392 tumor boards was collected from 22 institutions. The most common tumor board start time was at or before 0730 (24.6%). Surveys were completed by 111 physicians, of which 52.3% identified as women and 42.3% as men. Reported specialties were radiation oncology (39.6%), medical oncology (18.0%), surgery (15.3%), radiology (12.6%), and pathology (9.9%). On average, 41.4% attended ≥3 hours/week total of tumor boards and 1-2 hours/week of early/late tumor boards (defined as starting before 0800 or 1700 or after). Overall, 37.8% reported tumor boards were at least moderately burdensome. On multivariable analysis, radiology/pathology specialty (probability 0.68; 95% confidence interval [CI], 0.54-0.79; p = 0.015), attending ≥3 hours/week of tumor boards (probability 0.68; 95% CI, 0.58-0.76; p<.001), and having ≥2 children (probability 0.65; 95% CI, 0.52-0.77; p = 0.029), were associated with higher burden. Early/late tumor boards were frequently considered burdensome (20.7% moderately, 29.7% very burdensome). On multivariable analysis, identifying as a woman (probability 0.69; 95% CI, 0.57-0.78; p = 0.003) and having children (probability 0.75; 95% CI, 0.62-0.84; p<.001) remained associated with a higher level of burden from early/late tumor boards. Further, parents frequently reported that early/late tumor boards negatively affected childcare (55.8%), feeding and/or sleep logistics (33.8%), and overall family dynamics (63.7%).

CONCLUSION

Identifying as a woman and having children were associated with a higher level of burden from early/late tumor boards. The negative impact of early/late tumor boards on overall family dynamics, including children feeding, sleeping, and childcare logistics, was commonly reported by parents. Having ≥2 children, attending ≥3 hours/week of tumor boards, and radiology/pathology specialty were associated with a higher level of burden overall. Future strategies should aim to decrease burden, particularly the disparate impact on parents and women.

Convergence of Calcium Channel Regulation and Mechanotransduction in Skeletal Regenerative Biomaterial Design

Cells are known to perceive their microenvironment through extracellular and intracellular mechanical signals. Upon sensing mechanical stimuli, cells can initiate various downstream signaling pathways that are vital to regulating proliferation, growth, and homeostasis. One such physiologic activity modulated by mechanical stimuli is osteogenic differentiation. The process of osteogenic mechanotransduction is regulated by numerous calcium ion channels-including channels coupled to cilia, mechanosensitive and voltage-sensitive channels, and channels associated with the endoplasmic reticulum. Evidence suggests these channels are implicated in osteogenic pathways such as the YAP/TAZ and canonical Wnt pathways. This review aims to describe the involvement of calcium channels in regulating osteogenic differentiation in response to mechanical loading and characterize the fashion in which those channels directly or indirectly mediate this process. The mechanotransduction pathway is a promising target for the development of regenerative materials for clinical applications due to its independence from exogenous growth factor supplementation. As such, also described are examples of osteogenic biomaterial strategies that involve the discussed calcium ion channels, calcium-dependent cellular structures, or calcium ion-regulating cellular features. Understanding the distinct ways calcium channels and signaling regulate these processes may uncover potential targets for advancing biomaterials with regenerative osteogenic capabilities.
