RESUMO

SUMMARY: Nationwide abortion restrictions resulting from the Dobbs v. Jackson Women's Health Organization (2022) decision have generated confusion and uncertainty among healthcare professionals, with concerns for liability impacting clinical decision-making and outcomes. The impact on pediatric surgery can be seen in prenatal counseling for fetal anomaly cases, counseling for fetal intervention, and recommendations for pregnant children and adolescents who seek termination. It is essential that all physicians and healthcare team members understand the legal implications on their clinical practices, engage with resources and organizations which can help navigate these circumstances, and consider advocating for patients and themselves. Pediatric surgeons must consider the impact of these changing laws on their ability to provide comprehensive and ethical care and counseling to all patients.

RESUMO

BACKGROUND: The ripple effect of the Supreme Court ruling in Dobbs v. Jackson Women's Health Organization has impacted physicians and patients across numerous medical specialties. In pediatric surgery, the patient population ranges from fetus to the pregnant patient. There is a gap in the knowledge of pediatric surgeons regarding abortion laws and access. This project aims to bridge the gap by creating access to reliable resources which may be used to optimize patient care and support physicians. METHODS: We collaborated with the Reproductive Health Coalition, co-founded by the American Medical Women's Association and Doctors for America, to curate a list of resources beneficial to pediatric surgeons. RESULTS: We created a web-based toolkit with the purpose of providing easily accessible and reliable information on reproductive rights in the United States. We identified up-to-date resources on state-by-state abortion laws, legal resources, patient-centered information on obtaining abortion care, and resources for physicians interested in getting involved in advocacy. CONCLUSION: Pediatric surgery rests at a critical juncture with respect to reproductive rights in the United States. Our toolkit enables users to understand the current climate and identify next steps to advocate for patients and physicians amidst a formidable legal environment. LEVEL OF EVIDENCE: Level V.

RESUMO

Tumor budding (TB) is a powerful prognostic factor in colorectal cancer (CRC). An internationally standardized method for its assessment (International Tumor Budding Consensus Conference [ITBCC] method) has been adopted by most CRC pathology protocols. This method requires that TB counts are reported by field area (0.785 mm 2 ) rather than objective lens and a normalization factor is applied for this purpose. However, the validity of this approach is yet to be tested. We sought to validate the ITBCC method with a particular emphasis on normalization as a tool for standardization. In a cohort of 365 stage I-III CRC, both normalized and non-normalized TB were significantly associated with disease-specific survival and recurrence-free survival ( P <0.0001). Examining both 0.95 and 0.785 mm 2 field areas in a subset of patients (n=200), we found that normalization markedly overcorrects TB counts: Counts obtained in a 0.95 mm 2 hotspot field were reduced by an average of 17.5% following normalization compared with only 3.8% when counts were performed in an actual 0.785 mm 2 field. This resulted in 45 (11.3%) cases being downgraded using ITBCC grading criteria following normalization, compared with only 5 cases (1.3%, P =0.0007) downgraded when a true 0.785 mm 2 field was examined. In summary, the prognostic value of TB was retained regardless of whether TB counts in a 0.95 mm 2 field were normalized. Normalization resulted in overcorrecting TB counts with consequent downgrading of most borderline cases. This has implications for risk stratification and adjuvant treatment decisions, and suggests the need to re-evaluate the role of normalization in TB assessment.

RESUMO

OBJECTIVES: To conduct a qualitative study, guided by the principles of community-based participatory research, with the following objectives: (1) to provide a conceptual framework describing the drivers of son preference; (2) to understand experiences of son preference among Punjabi-Canadians and (3) with this understanding, identify and co-design an appropriate educational tool. DESIGN, SETTING, PARTICIPANTS, METHODS: Qualitative study consisting of four bilingual (Punjabi and English) focus group discussions with 11 mothers, 4 fathers and 17 grandmothers in Toronto and Brampton, Canada. Participants were queried about experiences and perspectives related to reproductive decision-making, gender equity and son preference, and for appropriate approaches to reducing inequities. Transcripts were simultaneously translated and written in English and thematic analysis was conducted. An infoposter was identified as a feasible educational tool and was co-designed by researchers and community partners. RESULTS: Participants identified patrilocality (ie, married sons reside with parents, married daughters with in-laws) and patrilineality (ie, sons inherit assets, daughters' husband receives a dowry) as structural precursors to proximal drivers (ie, old-age security) of son preference. Mothers' and grandmothers' value to their families depended strongly on having a son but did not guarantee security. Pressures (ie, internalised discrimination, reproductive coercion) to conceive a son were common after the birth of at least one daughter in the absence of sons. Participants did not know anyone who had a sex selective abortion in Canada; however, traditional sex selection methods (eg, herbal medicines) were mentioned. Our co-designed infoposter entitled 'Truths About Son Preference' addressed three misconceptions identified in discussions. CONCLUSION: This study may be useful to health and social care providers in providing structurally competent and culturally humble counselling and care, particularly after the birth of daughters in the absence of sons. Community engagement is necessary for future intervention development.

RESUMO

BACKGROUND: The objective of this study was to determine the influence of race/ethnicity and socioeconomic status (SES) on breast cancer outcomes. METHODS: A retrospective analysis was performed of Non-Hispanic Black (NHB), Non-Hispanic White (NHW), and Hispanic patients with non-metastatic breast cancer in the SEER cancer registry between 2007 and 2016. RESULTS: A total of 382,975 patients were identified. On multivariate analysis, NHB (OR 1.18, 95%CI: 1.15-1.20) and Hispanic (OR 1.20, 95%CI: 1.17-1.22) patients were more likely to present with higher stage disease than NHW patients. There was an increased likelihood of not undergoing breast-reconstruction for NHB (OR 1.07, 95%CI: 1.03-1.11) and Hispanic patients (OR 1.60, 95%CI 1.54-1.66). NHB patients had increased hazard for all-cause mortality (HR: 1.13, 95%CI 1.10-1.16). All-cause mortality increased across SES categories (lower SES: HR 1.33, 95%CI 1.30-1.37, middle SES: HR 1.20, 95%CI 1.17-1.23). CONCLUSIONS: This population-based analysis confirms worse disease presentation, access to surgical therapy, and survival across racial, ethnic, and socioeconomic factors. These disparities were compounded across worsening SES and insurance coverage.

RESUMO

BACKGROUND: Asian Canadians have experienced increased cases of racialized discrimination after the first emergence of SARS-CoV-2 in China. This study examined how the COVID-19 pandemic has affected Asian Canadians' sense of safety and belonging in their Canadian (i.e., geographical) communities. METHODS: We applied a qualitative description study design in which semistructured interviews were conducted from Mar. 23 to May 27, 2021. Purposive and snowball sampling methods were used to recruit Asian Canadians diverse in region, gender and age. Interviews were conducted through Zoom videoconference or telephone, and independent qualitative thematic analysis in duplicate was used to derive primary themes and subthemes. RESULTS: Thirty-two Asian Canadians (median age 35 [interquartile range 24-46] yr, 56% female, 44% East Asian) participated in the study. We identified 5 predominant themes associated with how the COVID-19 pandemic affected the participants' sense of security and belonging to their communities: relation between socioeconomic status (SES) and exposure to discrimination (i.e., how SES insulates or exposes individuals to increased discrimination); politics, media and the COVID-19 pandemic (i.e., the key role that politicians and media played in enabling spread of discrimination against and fear of Asian people); effect of discrimination on mental and social health (i.e., people's ability to interact and form meaningful relationships with others); coping with the impact of discrimination (i.e., the way people appraise and move forward in identity-threatening situations); and implications for sense of safety and sense of belonging (i.e., people feeling unable to safely use public spaces in person, including the need to remain alert in anticipation of harm, leading to distress and exhaustion). INTERPRETATION: During the COVID-19 pandemic, Asian Canadians in our study felt unsafe owing to the uncertain, unexpected and unpredictable nature of discrimination, but also felt a strong sense of belonging to Canadian society and felt well connected to their Asian Canadian communities. Future work should seek to explore the influence of social media on treatment of and attitudes toward Asian Canadians.

RESUMO

Tumor budding (TB) and poorly differentiated clusters (PDCs) are powerful prognostic factors in colorectal cancer (CRC). Despite their morphologic and biological overlap, TB and PDC are assessed separately and are distinguished by an arbitrary cutoff for cell cluster size. This cutoff can be challenging to apply in practice and its biological significance remains unclear. We developed a novel scoring system that incorporates TB and PDC into a single parameter ("Combined Score"; CS), eliminating the need for such cutoffs and allowing the prognostic value of PDC to be captured alongside TB. In a cohort of 481 stage I-III CRC resections, CS was significantly associated with American Joint Committee on Cancer (AJCC) stage, T-stage, N-stage, histologic grade, tumor deposits, lymphovascular invasion, and perineural invasion ( P <0.0001). In addition, CS was significantly associated with decreased 5-year recurrence-free survival, overall survival, and disease-specific survival ( P <0.0001). TB and PDC showed similar associations with oncologic outcomes, with hazard ratios consistently lower than for CS. The association between CS and oncologic outcomes remained significant in subgroup analyses stratified by AJCC stage, anatomic location (rectum/colon) and neoadjuvant therapy status. On multivariable analysis, CS retained its significant association with oncologic outcomes ( P =0.0002, 0.005, and 0.009) for recurrence-free survival, disease-specific survival, and overall survival, respectively. In conclusion, CS provides powerful risk stratification in CRC which is at least equivalent to that of TB and PDC assessed individually. If validated elsewhere, CS has practical advantages and a biological rationale that may make it an attractive alternative to assessing these features separately.

RESUMO

Venous invasion (VI) is a powerful yet underreported prognostic factor in colorectal cancer (CRC). Its detection can be improved with an elastin stain. We evaluated the impact of routine elastin staining on VI detection in resected CRC and its relationship with oncologic outcomes. Pathology reports from the year before (n=145) and the year following (n=128) the implementation of routine elastin staining at our institution were reviewed for established prognostic factors, including VI. A second review, using elastin stains, documented the presence/absence, location, number, and size of VI foci. The relationship between VI and oncologic outcomes was evaluated for original and review assessments. VI detection rates increased from 21% to 45% following implementation of routine elastin staining (odds ratio [OR]=3.1; 95% confidence interval [CI]: 1.8-5.3; P<0.0001). The second review revealed a lower VI miss rate postimplementation than preimplementation (22% vs. 48%, respectively; P=0.007); this difference was even greater for extramural VI-positive cases (9% vs. 38%, respectively; P=0.0003). Missed VI cases postimplementation had fewer VI foci per missed case (P=0.02) and a trend towards less extramural VI than those missed preimplementation. VI assessed with an elastin stain was significantly associated with recurrence-free survival (P=0.003), and cancer-specific survival (P=0.01) in contrast to VI assessed on hematoxylin and eosin alone (P=0.053 and 0.1, respectively). The association between VI and hematogenous metastasis was far stronger for elastin-detected VI (OR=11.5; 95% CI: 3.4-37.1; P<0.0001) than for hematoxylin and eosin-detected VI (OR=3.7; 95% CI: 1.4-9.9; P=0.01). Routine elastin staining enhances VI detection and its ability to stratify risk in CRC and should be considered for evaluation of CRC resection specimens.

RESUMO

OBJECTIVE: To assess the prevalence, magnitude, and disclosure status of industry funding in editorial boards of surgery journals. SUMMARY OF BACKGROUND DATA: Financial COI can bias research. Although authors seeking to publish in peer-reviewed surgery journals are required to provide COI disclosures, editorial board members' COI disclosures are generally not disclosed to readers. METHODS: We present a cross-sectional analysis of industry funding to editorial board members of high-impact surgery journals. We reviewed top US-based surgery journals by impact factor to determine the presence of financial COI in members of each journal's editorial board. The prevalence and magnitude of COI was determined using 2018 industry reported payments found in the Centers for Medicare and Medicaid Services Open Payments database. Journal websites were also reviewed looking for the presence of editorial board disclosure statements. RESULTS: A total of 1002 names of editorial board members from the top 10 high-impact American surgery journals were identified. Of 688 individual physicians based in the USA, 452 (65.7%) were found to have received industry payments in 2018, totaling $21,916,503 with a median funding amount per physician of $1253 (interquartile range $156-$10,769). Funding levels varied by surgical specialty and journal. Editorial board disclosure information was found in only 3.3% of physicians. CONCLUSIONS: Industry funding to editorial board members of high impact surgery journals is prevalent and underreported. Mechanisms of disclosure for COI are needed at the editorial board level to provide readers full transparency. This would acknowledge this COI of editorial board members, and thereby attempt to potentially further reduce the risk of bias in editorial decisions.

RESUMO

AIM OF THE STUDY: Appendiceal carcinoid (neuroendocrine tumor or NET) is a rare neuroendocrine neoplasm often found incidentally following appendectomy for appendicitis. Surgery for appendicitis is currently under scrutiny and children are increasingly managed conservatively with antibiotics alone. Herein, we aimed to review our experience with the management of appendiceal carcinoids at our institution. METHODS: Following ethical approval, we reviewed the charts of all patients who underwent appendectomy for appendicitis at our institution between 2000 and 2018. The pathology registry was consulted to identify children diagnosed with appendiceal carcinoid. Outcome measures included incidence, demographics, and management. MAIN RESULTS: During the study period, 32 children (23 female) had an appendiceal carcinoid confirmed at pathology. Of these, 13 were initially treated with appendectomy (total of 5,059 appendectomies: 0.3% incidence). The other 19 had an appendectomy elsewhere by an adult general surgeon and were referred to our institution for further management. Overall, the mean age at diagnosis was 13 ± 2.7 years and all patient had a preoperative diagnosis of appendicitis, none of suspected carcinoid. Most children (75%) had acute non-perforated appendicitis. The overall mean size of the lesion was 1 ± 0.9 cm, with a > 2 cm lesion in 3 patients. Following diagnosis, 12 children (38%) underwent an ileocolic resection, due to carcinoid size, invasiveness, and margin clearance. CONCLUSIONS: In our cohort, the incidence of appendiceal carcinoid among children with appendicitis is very low. Most carcinoids are small, located at the tip, associated with non-perforated appendicitis, and present in girls. Most were treated with appendectomy alone, with more extensive surgery performed in one third of children.

RESUMO

Anticoagulation is used to prevent thromboembolism; inferior vena cava filters are an alternative in patients with contraindications to anticoagulation. Although it is safe and effective, there are recognized complications related to inferior vena cava filter placement. We describe the case of a young man with congenital solitary left pelvic kidney who required unique filter placement to suit the anatomy and surgical removal after entrapment of the filter-snare complex in the left internal iliac vein. Patients may also acquire solitary pelvic kidneys after renal transplantation. This anatomy poses unique challenges to venous filter placement and requires tailored management.

RESUMO

OBJECTIVES: To examine whether son-biased male to female (M:F) ratios at birth among linguistically different subgroups of Indian immigrants vary according to duration of residence in Canada. METHODS: We analyzed a retrospective cohort of 46 834 live births to Indian-born mothers who gave birth in Canada between 1993 and 2014. The M:F ratio at birth was calculated according to the sex of previous live births and stratified by (1) time since immigration to Canada (<10 and ≥10 years) and (2) mother tongue (Punjabi, Gujarati, Hindi, and other). We estimated adjusted odds ratios (aORs) using multivariate logistic regression to assess the probability of having a male newborn with 5-year increases in duration of residence in Canada for each language group. ORs were adjusted for married status, knowledge of English/French, maternal education at arrival and age and neighbourhood income at delivery. RESULTS: Among all Indian immigrant women with two previous daughters, M:F ratios were higher than expected (1.92, 95% CI 1.73-2.12), particularly among those whose mother tongue was Punjabi (n = 25 287) (2.40, 95% CI 2.11-2.72) and Hindi (n = 7752) (1.63, 95% CI 1.05-2.52). M:F ratios did not diminish with longer duration in Canada (Punjabi 5-year aOR 1.03, 95% CI 0.81-1.31; Hindi 5-year aOR 0.94, 95% CI 0.42-2.17). CONCLUSION: Among the Punjabi and Hindi women with two previous daughters, longer duration of residence did not attenuate son-biased M:F ratios at the third birth. Gender equity promotion may focus on Punjabi- and Hindi-speaking Indian immigrant women regardless of how long they have lived in Canada.

RESUMO

We examined the hypothesis that the factor V Leiden (FVL) and G20101A prothrombin gene mutations are commonly associated with hip osteonecrosis. We prospectively evaluated 244 consecutively referred adults with osteonecrosis (ON), 161 idiopathic and 83 secondary. Cases (n = 244) did not differ from 104 normal controls by race. Of the 244 patients, 23 (9.4%) were FVL heterozygotes versus 2 of 104 controls (1.9%), P = .013, risk ratio (RR) = 4.90, 95% confidence interval (CI) 1.18 to 20.4. Of the 161 patients with idiopathic ON, 15 (9.3%) were FVL heterozygotes versus 2 of 104 normal controls (1.9%), P = .017, RR = 4.84, 95% CI 1.13 to 20.8. Of the 83 patients with secondary ON, 8 (9.6%) FVL heterozygotes versus 2 of 104 normal controls (1.9%), P = .024, RR = 5.01, 95% CI 1.09 to 23.0. Prothrombin gene heterozygosity in normal controls (2.9%) did not differ from ON cases (3.4%), P = 1.0. The thrombophilic FVL mutation is commonly associated with and may be pathoetiologic for hip osteonecrosis.
