Hidden morbidity of ethanol lock therapy.

AIMS: Long-term central venous catheters are essential in sustaining growth and development in patients with intestinal failure (IF). Several strategies have been developed to prevent and treat catheter-related blood stream infections (CRBSIs), including ethanol lock therapy. We sought to evaluate the efficacy of ethanol lock therapy in our IF population. METHOD: This is a retrospective review of IF patients treated with ethanol lock therapy at a single institution from 2006 to 2013. We evaluated the number of catheter days, rate of CRBSI per 1000 catheter days, rate of central venous catheter (CVC) thrombosis, rate of CVC breakage, total number of CVC replacements, total number of hospital admissions, and total number days in the hospital. RESULT: We identified 19 patients who underwent ethanol lock therapy for CRBSI. There was no difference in CRBSI rate prior to (5.6 per 1000 catheter days) and after (7 per 1000 catheter days) initiation of ethanol lock therapy. The mean rate of thrombosis increased from 0 to 3 per 1000 catheter days with ethanol lock therapy (p < 0.05). In addition, the CVC breakage rate increased from 0 to 13.7 per 1000 catheter days with ethanol lock therapy (p < 0.001). Hospital admissions and catheter-related ER visits increased following the initiation of ethanol lock therapy. CONCLUSIONS: Contrary to other studies, there was no difference in CRBSI rate prior to and after initiation of ethanol lock therapy. Factors in the methodology of ethanol lock therapy may influence the effectiveness of infection prevention associated with ethanol lock therapy, as well as the rate of line breakage, line thrombosis, and the need for line replacement.

Debunking Myths of Gender Informed Care: What Every Pediatric Surgeon Should Know.

As the transgender population in the United States grows, gender-affirming care is becoming increasingly relevant to the practice of pediatric surgery. Medical care for the transgender and gender diverse population is a politically charged topic with significant complexity and opportunities for clarification. It is important for providers to better understand this population's unique health and social needs. This review aims to debunk long-standing myths regarding gender-affirming care and highlight the current therapeutic and legislative landscapes within the scope of pediatric surgical practice. LEVEL OF EVIDENCE: IV.

APSA Members experience bias and discrimination in training and practice.

INTRODUCTION: Bias and discrimination remain pervasive in the medical field and increase the risk of burnout, mental health disorders, and medical errors. The experiences of APSA members with bias and discrimination are unknown, therefore the APSA committee on Diversity, Equity and Inclusion conducted a survey to characterize the prevalence of bias and discrimination. METHODS: 1558 APSA members were sent an anonymous survey, of which 423 (27%) responded. Respondents were asked about their demographics, knowledge of implicit bias, and experience of bias and discrimination within their primary workplace, APSA, and APSA committees. Data were analyzed using Fisher's Exact test, Kruskal-Wallis test, and multivariable logistic regression as appropriate with significance defined as p<0.05. RESULTS: Discrimination was reported across all levels of practice, academic appointments, race, ethnicity, and gender identities. On multivariable analysis, surgical trainees (OR 3.6) as well as Asian American and Pacific Islander (OR 4.8), Black (OR 5.2), Hispanic (OR 8.2) and women (OR 8.7) surgeons were more likely to experience bias and discrimination in the workplace. Community practice surgeons were more likely to experience discrimination within APSA committees (OR 3.6). Members identifying as Asian (OR 0.4), or women (OR 0.6) were less likely to express comfort reporting instances of bias and discrimination. CONCLUSION: Workplace discrimination exists across all training levels, academic appointments, and racial and gender identities. Trainees and racial- and gender-minority surgeons report disproportionately high prevalence of bias and discrimination. Improving reporting mechanisms and implicit bias training are possible initiatives in addressing these findings.

Diversity and demographics of APSA members: Understanding our identity.

INTRODUCTION: There are existing healthcare disparities in pediatric surgery today. Identity and racial incongruity between patients and providers contribute to systemic healthcare inequities and negatively impacts health outcomes of minoritized populations. Understanding the current demographics of the American Pediatric Surgical Association and therefore the cognitive diversity represented will help inform how best to strategically build the organization to optimize disparity solutions and improve patient care. METHODS: 1558 APSA members were sent an anonymous electronic survey. Comparative data was collected from the US Census Bureau and the Association of American Medical Colleges. Results were analyzed using standard statistical tests. RESULTS: Of 423 respondents (response rate 27%), the race and ethnicity composition were 68% non Hispanic White, 12% Asian American and Pacific Islander, 6% Hispanic, 5% multiracial, and 4% Black/African American. Respondents were 35% women, 63% men, and 1% transgender, androgyne, or uncertain. Distribution of sexual identity was 97% heterosexual and 3% LGBTQIA. Religious identity was 50% Christian, 22% Agnostic/Atheist, 11% Jewish, 3% Hindu, and 2% Muslim. 32% of respondents were first-generation Americans. Twenty-four different primary languages were spoken, and 46% of respondents were conversational in a second language. These findings differ in meaningful ways from the overall American population and from the population of matriculants in American medical schools. CONCLUSION: There are substantial differences in the racial, gender, and sexual identity composition of APSA members compared with the overall population in the United States. To achieve excellence in patient care and innovate solutions to existing disparities, representation, particularly in leadership is essential. TYPE OF STUDY: Survey; original research.

The fibronectin synergy site modulates TGF-beta-dependent fibroblast contraction.

Tissue remodeling following injury involves TGF-beta-mediated fibroblast contraction. While these cells are embedded in a fibronectin (FN)-rich matrix, the role of FN-cell interactions in this process is not fully understood. To explore the role of FN matrix presentation, we analyzed the effect of TGF-beta on fibroblasts adhered to FN-coated polyacrylamide gels (PAG). Surprisingly, under these conditions TGF-beta triggered cell rounding/contraction. This was accompanied by increased Rho activation and MLC phosphorylation and was reversed by inhibition of Rho kinase. Although fibroblasts are known to bind to fibronectin's RGD and synergy sites, their relative contribution to cell function is not clear. MLC phosphorylation was reduced and cell contraction was reversed when FN's synergy site was blocked, indicating that contraction requires signals from the synergy site in addition to TGF-beta-mediated Rho activation. Thus, regulating the FN synergy site therapeutically may provide a mechanism for modulating contractile forces during tissue repair.
