RESUMO

BACKGROUND: Cardiovascular conditions are considered risk factors for poor outcomes associated with COVID-19. However, the effect of the COVID-19 pandemic on the mortality of patients with congenital heart disease (CHD) is unclear. Our study aims to examine the trends in mortality risk of CHD patients during the COVID-19 pandemic. METHODS: This is a retrospective cohort study from the Pediatric Cardiac Care Consortium, a US-based registry of interventions for CHD. We included patients having US residence and direct identifiers; death events were captured by matching with the National Death Index. The observation window (2017-2022) was divided into pre-COVID-19 and COVID-19 era defined around the national onset of COVID-19 disease in 2020. Stratified Cox model was used to assess all-cause mortality between the pre- and the COVID-19 era. RESULTS: Among 45,130 patients with CHD (median age in 2017: 23.3 years, IQR: 19.0-28.4), 503 deaths occurred during the pandemic with 44 deaths (8.7%) attributed to COVID-19 (COVID-19 mortality rate of 0.09%). The overall risk of death for patients with all types of CHD during the pandemic was significantly higher compared to the pre-COVID-19 era (aHR 1.28, 95%CI: 1.08-1.53), with a differential trend towards increased risk in patients with two-ventricle (aHR 1.44, 95% CI: 1.19-1.76) vs unchanged risk for those with single ventricle CHD (aHR = 0.83, 95% CI: 0.57-1.21). Adjusted subgroup analysis revealed a higher risk of death during the pandemic for CHD patients with male and chromosomal abnormalities. The excess deaths during the pandemic were attributed to COVID-19 itself rather than CHD or cardiovascular conditions. CONCLUSION: In this large CHD cohort study, there was a higher risk of death among CHD patients with male and chromosomal abnormalities. A differential trend towards higher risk for those with two vs. unchanged risk for single ventricle CHD was presented. The excess mortality was attributed to the COVID-19 itself and not to conditions potentially related to deferral of care. These results justify targeted protective measures towards the CHD population and may provide guidance for public health and medical care response in future epidemics.

RESUMO

BACKGROUND: The Fontan operation is used to palliate single ventricle congenital heart defects (CHD) but poses significant morbidity and mortality risks. We present the design, planned analyses, and rationale for a long-term Fontan cohort study aiming to examine the association of patient characteristics at the time of Fontan with post-Fontan morbidity and mortality. METHODS AND RESULTS: We used the Pediatric Cardiac Care Consortium (PCCC), a US-based, multicenter registry of pediatric cardiac surgeries to identify patients who underwent the Fontan procedure for single ventricle CHD between 1 and 21 years of age. The primary outcomes are in-hospital Fontan failure (death or takedown) and post-discharge mortality through 2022. A total of 1461 (males 62.1%) patients met eligibility criteria and were included in the analytical cohort. The median age at Fontan evaluation was 3.1 years (IQR: 2.4-4.3). While 95 patients experienced in-hospital Fontan failure (78 deaths and 17 Fontan takedown), 1366 (93.5%) survived to discharge with Fontan physiology and formed the long-term analysis cohort. Over a median follow-up of 21.2 years (IQR: 18.4-24.5) 184 post-discharge deaths occurred. Thirty-year post Fontan survival was 75.0% (95% CI: 72.3%-77.8%) for all Fontan types with higher rates for current techniques such as lateral tunnel and extracardiac conduit 77.1% (95% CI: 73.5-80.8). CONCLUSION: The PCCC Fontan study aims to identify predictors for post-Fontan morbidity and mortality, enabling risk- stratification and informing surveillance practices. Additionally, the study may guide therapeutic interventions aiming to optimize hemodynamics and enhance Fontan longevity for individual patients.

RESUMO

Flatfoot deformity consists of collapse of the medial arch, forefoot abduction, increased talonavicular uncoverage, and hindfoot valgus. Although numerous soft tissue and bony procedures have been proposed to correct each plane of deformity, there is a lack of objective data in the literature quantifying the amount of structural correction. The purpose of this study was to quantify the multiplanar deformity correction of the lateral column lengthening osteotomy (Evans) on hindfoot alignment through objective, reproducible, radiographic measurements. We retrospectively reviewed 45 Evans calcaneal osteotomy procedures in 24 female (53%) and 21 male (47%) feet performed on 40 patients (5 bilateral). The mean follow-up was 53 weeks (range, 32-116). The mean age at the time of surgery was 35 years (range, 11-73). Statistically significant improvement in radiographic alignment was found in the calcaneal inclination angle, tibial-calcaneal angle, tibial-calcaneal position, and the anteroposterior talo-first metatarsal angle (p < .0001 for all). Although a direct correlation between graft size and degree of angular correction was not observed, it should be noted the calcaneal graft size (mean, 11.8 mm) and the amount of hindfoot valgus correction (mean, 12.6°) appear to be clinically related. The results of this study support that the Evans calcaneal osteotomy corrects the hindfoot alignment in 3 planes as evidenced by our multiplanar radiographic measurements.

RESUMO

OBJECTIVE: To evaluate long-term transplant-free survival and causes of death in the trisomy 21 (T21) population after surgery for congenital heart disease (CHD) in comparison with patients who are euploidic. STUDY DESIGN: This is a retrospective cohort study from the Pediatric Cardiac Care Consortium, enriched with prospectively collected data from the National Death Index and the Organ Procurement and Transplantation Network for patients with sufficient direct identifiers. Kaplan-Meier survival plots were generated and multivariable Cox proportional hazards models were used to examine risk factors for mortality between patients with T21 and 1:1 matched patients with comparable CHD who are euploidic. RESULTS: A long-term survival analysis was completed for 3376 patients with T21 (75 155 person-years) who met inclusion criteria. The 30-year survival rate for patients with T21 ranged from 92.1% for ventricular septal defect to 65.3% for complex common atrioventricular canal. Of these, 2185 patients with T21 were successfully matched with a patient who was euploidic. After a median follow-up of 22.86 years (IQR, 19.45-27.14 years), 213 deaths occurred in the T21 group (9.7%) compared with 123 (5.6%) in the euploidic comparators. After adjustment for age, sex, era, CHD complexity, and initial palliation, the hazard ratio of CHD-related mortality was 1.34 times higher in patients with T21 (95% CI, 0.92-1.97; P = .127). CONCLUSIONS: CHD-related mortality for patients with T21 after cardiac surgical intervention is comparable with euploidic comparators. Children with T21 require lifelong surveillance for co-occurring conditions associated with their chromosomal abnormality.

RESUMO

Inadequate diet is the leading risk factor for morbidity and mortality worldwide. However, approaches to identifying inadequate diets in clinical practice remain inconsistent, and dietary interventions (on both individual and public health policy levels) frequently focus on facilitating 'healthy choices', with limited emphasis on structural constraints. We examine the ethical implications of introducing a routine question in the medical history about ability to access food. Not collecting data on food security means that clinicians are unable to identify people who may benefit from support on an individual level, unable to consider relevant dietary risk factors for disease and disease progression and unable to monitor population trends and inequalities in dietary access in order to design effective policy interventions. We argue that the current lack of routine screening for food insecurity is inconsistent with our approach to other health behaviours (eg, smoking and alcohol use), as well as with doctors' frequent informal role as gatekeepers to the food aid system, and recent calls for governmental action on food insecurity and health inequalities from individual clinicians and professional bodies. Potential ethical barriers to asking patients about food security are addressed, including concerns about stigma, limiting autonomy, fair resource allocation, unclear professional remits and clinicians' ability to offer effective interventions. We suggest that there is an ethical imperative for doctors to ask patients about their ability to access healthy food. Gathering this data provides a valuable first step in re-framing the social determinants of health as modifiable risks, rather than inevitable inequities.

RESUMO

BACKGROUND: The significance of DNA mismatch repair (MMR) deficiency in ampullary cancers (ACs) has not been established. METHODS: In total, 127 ACs with invasive carcinomas measuring ≥3 mmthat had adequate tissue were analyzed immunohistochemically. RESULTS: MMR loss was detected in 18% of ACs (higher than in colorectal cancers). Twelve tumors with MLH1-PMS2 loss were negative for BRAF V600E mutation, suggesting a Lynch syndrome association. MMR-deficient tumors (n = 23), comparedwith MMR-intact tumors (n = 104), showed a striking male predominance (male:female ratio, 4.7). Although the deficient tumors had slightly larger invasion size (2.7 vs 2.1 cm), they also had more expansile growth and less invasiveness, including less perineural invasion, and they ultimately had lower tumor (T) classification and less lymph node metastasis (30% vs 53%; P = .04). More important, patients who had MMR-deficient tumors had better clinical outcomes, with a 5-year overall survival rate of 68% versus 45% (P = .03), which was even more pronounced in those who had higher Tclassification (5-year overall survival, 69% vs 34%; P = .04). MMR deficiencyhad a statistically significant association with medullary phenotype, pushing-border invasion, and tumor-infiltrating immune cells, and it occurred more frequently in ampullary-duodenal type tumors. Programed cell death-ligand 1 (PD-L1) levels analyzed in the 22 MMR-deficient ACs revealed that all medullary carcinomas were positive. Nonmedullary MMR-deficient carcinomas expressed PD-L1 in 33% of tumors cells according to the criteria for a combined positive score ≥1, but all were negative according to the tumor proportion score≥1 method. CONCLUSIONS: In ACs, MMR deficiency is even more frequent (18%) than in colon cancer and often has a Lynch-suggestive profile, thus routine testing is warranted. Male gender, pushing-border infiltration, ampullary-duodenal origin, medullary histology, and tumor-related inflammation have a significantly higher association with MMR deficiency. MMR-deficient tumors have less aggressive behavior. PD-L1 expression is common in medullary-phenotype ACs, thus immunotherapy should be considered at least for this group.

RESUMO

Impetigo, scabies, cellulitis and abscesses are common in Australian Aboriginal children. These conditions adversely affect wellbeing and are associated with serious long term sequelae, including invasive infection and post-infectious complications, such as acute post-streptococcal glomerulonephritis and acute rheumatic fever, which occurs at the highest documented rates in the world in remote Aboriginal communities. Observational research in remote communities in northern Australia has demonstrated a high concurrent burden of scabies and impetigo and their post-infectious complications. Few data are available for other Australian states, especially for urban Aboriginal children; however, nationwide hospital data indicate that the disparity between Aboriginal and non-Aboriginal children in skin infection prevalence also exists in urban settings. The Australian National Healthy Skin Guideline summarises evidence-based treatment of impetigo, scabies and fungal infections in high burden settings such as remote Aboriginal communities. It recommends systemic antibiotics for children with impetigo, and either topical permethrin or oral ivermectin (second line) for the individual and their contacts as equally efficacious treatments for scabies. ß-Lactams are the treatment of choice and trimethoprim-sulfamethoxazole and clindamycin are effective alternatives for treatment of paediatric cellulitis. Abscesses require incision and drainage and a 5-day course of trimethoprim-sulfamethoxazole or clindamycin. Addressing normalisation of skin infections and the social determinants of skin health are key challenges for the clinician. Research is underway on community-wide skin health programs and the role for mass drug administration which will guide future management of these common, treatable diseases.

RESUMO

Delayed regenerate healing after distraction osteogenesis can be a challenging problem for patients and surgeons alike. In the present study, we retrospectively reviewed the data from a cohort of patients with delayed regenerate healing during gradual lengthening treatment of brachymetatarsia. Additionally, we present a novel technique developed by 1 of us (B.M.L.) for the management of delayed regenerate healing. We hypothesized that application of intramedullary metatarsal fixation would safely and effectively promote healing of poor quality, atrophic regenerate during bone lengthening in brachymetatarsia correction. We formulated a study to retrospectively review the data from a cohort of patients with delayed regenerate healing after gradual lengthening for brachymetatarsia. All patients underwent temporary placement of intramedullary fixation after identification of delayed regenerate healing. Patient-related variables and objective measurements were assessed. We identified 10 patients with 13 metatarsals treated with intramedullary fixation for delayed regenerate healing. All 10 patients were female, with 6 (46.2%) right metatarsals and 7 (53.8%) left metatarsals treated. No complications developed with the use of this technique. All subjects progressed to successful consolidation of the regenerate bone at a mean of 44.5 ± 30.2 days after placement of intramedullary metatarsal fixation. No regenerate fracture or reoperations were noted. In conclusion, intramedullary metatarsal fixation is a safe and effective method for managing delayed regenerate healing encountered during distraction osteogenesis correction of brachymetatarsia.

RESUMO

Literature on non-ampullary-duodenal carcinomas is limited. We analyzed 47 resected non-ampullary-duodenal carcinomas. Histologically, 78% were tubular-type adenocarcinomas mostly gastro-pancreatobiliary type and only 19% pure intestinal. Immunohistochemistry (n=38) revealed commonness of 'gastro-pancreatobiliary markers' (CK7 55, MUC1 50, MUC5AC 50, and MUC6 34%), whereas 'intestinal markers' were relatively less common (MUC2 36, CK20 42, and CDX2 44%). Squamous and mucinous differentiation were rare (in five each); previously, unrecognized adenocarcinoma patterns were noted (three microcystic/vacuolated, two cribriform, one of comedo-like, oncocytic papillary, and goblet-cell-carcinoid-like). An adenoma component common in ampullary-duodenal cancers was noted in only about a third. Most had plaque-like or ulcerating growth. Mismatch repair protein alterations were detected in 13% (all with plaque-like growth and pushing-border infiltration). When compared with ampullary (n=355) and pancreatic ductal (n=227) carcinomas, non-ampullary-duodenal carcinomas had intermediary pathologic features with mean invasive size of 2.9 cm (vs 1.9, and 3.3) and 59% nodal metastasis (vs 45, and 77%). Its survival (3-, 5-year rates of 57 and 57%) was similar to that of ampullary-duodenal carcinomas (59 and 52%; P=0.78), but was significantly better than the ampullary ductal (41 and 29%, P<0.001) and pancreatic (28 and 18%, P<0.001) carcinomas. In conclusion, non-ampullary-duodenal carcinomas are more histologically heterogeneous than previously appreciated. Their morphologic versatility (commonly showing gastro-pancreatobiliary lineage and hitherto unrecognized patterns), frequent plaque-like growth minus an adenoma component, and frequent expression of gastro-pancreatobiliary markers suggest that many non-ampullary-duodenal carcinomas may arise from Brunner glands or gastric metaplasia or heterotopic pancreatobiliary epithelium. The clinical behavior of non-ampullary-duodenal carcinoma is closer to that of ampullary-duodenal subset of ampullary carcinomas, but is significantly better than that of ampullary ductal and pancreatic cancers. The frequency of mismatch repair protein alterations suggest that routine testing should be considered, especially in the non-ampullary-duodenal carcinomas with plaque-like growth and pushing-border infiltration.

RESUMO

Distal common bile duct carcinoma is a poorly characterized entity for reasons such as variable terminology and difficulty in determining site of origin of intrapancreatic lesions. We compared clinicopathologic features of pancreatobiliary-type adenocarcinomas within the pancreas, but arising from the distal common bile duct, with those of pancreatic and ampullary origin. Upon careful review of 1017 pancreatoduodenectomy specimens with primary adenocarcinoma, 52 (5%) qualified as intrapancreatic distal common bile duct carcinoma. Five associated with an intraductal papillary neoplasm were excluded; the remaining 47 were compared to 109 pancreatic ductal adenocarcinomas and 133 ampullary carcinomas. Distal common bile duct carcinoma patients had a younger median age (58 years) than pancreatic ductal adenocarcinoma patients (65 years) and ampullary carcinoma patients (68 years). Distal common bile duct carcinoma was intermediate between pancreatic ductal adenocarcinoma and ampullary carcinoma with regard to tumor size and rates of node metastases and margin positivity. Median survival was better than for pancreatic ductal adenocarcinoma (P=0.0010) but worse than for ampullary carcinoma (P=0.0006). Distal common bile duct carcinoma often formed an even band around the common bile duct and commonly showed intraglandular neutrophil-rich debris and a small tubular pattern. Poor prognostic indicators included node metastasis (P=0.0010), lymphovascular invasion (P=0.0299), and margin positivity (P=0.0069). Categorizing the tumors based on size also had prognostic relevance (P=0.0096), unlike categorization based on anatomic structures invaded. Primary distal common bile duct carcinoma is seen in younger patients than pancreatic ductal adenocarcinoma or ampullary carcinoma. Its prognosis is significantly better than pancreatic ductal adenocarcinoma and worse than ampullary carcinoma, at least partly because of differences in clinical presentation. Use of size-based criteria for staging appears to improve its prognostic relevance. Invasive pancreatobiliary-type distal common bile duct carcinomas are uncommon in the West and have substantial clinicopathologic differences from carcinomas arising from the pancreas and ampulla.

RESUMO

High-grade versions of appendiceal goblet cell carcinoids ('adenocarcinoma ex-goblet cell carcinoids') are poorly characterized. We herein document 77 examples. Tumors occurred predominantly in females (74%), mean age 55 years (29-84), most with disseminated abdominal (77% peritoneal, 58% gynecologic tract involvement) and stage IV (65%) disease. Many presented to gynecologic oncologists, and nine had a working diagnosis of ovarian carcinoma. Metastases to liver (n=3) and lung (n=1) were uncommon and none arose in adenomatous lesions. Tumors had various histologic patterns, in variable combinations, most of which were fairly specific, making them recognizable as appendiceal in origin, even at metastatic sites: I: Ordinary goblet cell carcinoid/crypt pattern (rounded, non-luminal acini with well-oriented goblet cells), in variable amounts in all cases. II: Poorly cohesive goblet cell pattern (diffusely infiltrative cords/single files of signet ring-like/goblet cells). III: Poorly cohesive non-mucinous cell (diffuse-infiltrative growth of non-mucinous cells). IV: Microglandular (rosette-like glandular) pattern without goblet cells. V: Mixed 'other' carcinoma foci (including ordinary intestinal/mucinous). VI: goblet cell carcinoid pattern with high-grade morphology (marked nuclear atypia). VII: Solid sheet-like pattern punctuated by goblet cells/microglandular units. Ordinary nested/trabecular ('carcinoid pattern') was very uncommon. In total, 33(52%) died of disease, with median overall survival 38 months and 5-year survival 32%. On multivariate analysis perineural invasion and younger age (<55) were independently associated with worse outcome while lymph-vascular invasion, stage, and nodal status trended toward, but failed to reach, statistical significance. Worse behavior in younger patients combined with female predilection and ovarian-affinity raise the possibility of hormone-assisted tumor progression. In conclusion, 'adenocarcinoma ex-goblet cell carcinoid' is an appendix-specific, high-grade malignant neoplasm with distinctive morphology that is recognizable at metastatic sites and recapitulates crypt cells (appendiceal crypt cell adenocarcinoma). Unlike intestinal-type adenocarcinoma, it occurs predominantly in women, is disguised as gynecologic malignancy, and spreads along peritoneal surfaces with only rare hematogenous metastasis. It appears to be significantly more aggressive than appendiceal mucinous neoplasms.

RESUMO

BACKGROUND: Most studies have failed to identify any prognostic value of the current T-stage protocol for pancreatic ductal adenocarcinoma (PDAC) by the American Joint Committee on Cancer and the Union for International Cancer Control unless some grouping was performed. METHODS: To document the parameters included in this T-stage protocol, 223 consecutive pancreatoduodenectomy specimens with PDAC were processed by a uniform grossing protocol. RESULTS: Peripancreatic soft tissue (PST) involvement, the main pT3 parameter, was found to be inapplicable and irreproducible due to lack of a true capsule in the pancreas and variability in the amount and distribution of adipose tissue. Furthermore, 91 % of the cases showed carcinoma in the adipose tissue, presumably representing the PST, and thus were classified as pT3. An additional 4.5 % were qualified as pT3 due to extension into adjacent sites. The T-stage defined as such was not found to have any correlation with survival (p = 0.4). A revised T-stage protocol was devised that defined pT1 as 2 cm or smaller, pT2 as >2-4 cm, and pT3 as larger than 4 cm. This revised protocol was tested in 757 consecutive PDACs. The median and 3-year survival rates of this size-based protocol were 26, 18, 13 months, and 40 %, 26 %, 20 %, respectively (p < 0.0001). The association between higher T-stage and shorter survival persisted in N0 cases and in multivariate modeling. Analysis of the Surveillance, Epidemiology, and End Results database also confirmed the survival differences (p < 0.0001). CONCLUSIONS: This study showed that resected PDACs are already spread to various surfaces of the pancreas, leaving only about 4 % of PDACs to truly qualify as pT1/T2, and that the current T-stage protocol does not have any prognostic correlation. In contrast, as shown previously in many studies, size is an important prognosticator, and a size-based T-stage protocol is more applicable and has prognostic value in PDAC.

RESUMO

BACKGROUND: The transition shock or Imposter Phenomena sometimes associated with moving from student to Registered Nurse can lead to feelings of self-doubt and insecurity especially with the increased expectations and responsibilities that registration brings. AIM: The aim of this study was to examine the extent at which imposter phenomenon is evident in four final year nursing student cohorts in Australia, New Zealand and the UK. DESIGN: A survey design. SETTINGS: The study took place at four higher education institutes - two metropolitan campuses and two regional campuses between October 2014 - February 2015 in Australia, New Zealand and the UK. A sample of 223 final year nursing students undertaking nationally accredited nursing programmes were approached. RESULTS: Each cohort exhibited mild to moderate feelings of Imposter Phenomena. A positive weak correlation between imposter phenomena and preparedness for practice was found. The New Zealand cohort scored higher than both the Australian and UK cohorts on both feelings of imposterism and preparedness for practice. CONCLUSIONS: Nursing students possess internalized feelings which suggest their performance and competence once qualified could be compromised. There is some speculation that the respective curriculums may have some bearing on preparing students for registration and beyond. It is recommended that educational programmes designed for this student cohort should be mindful of this internal conflict and potential external hostility.

RESUMO

BACKGROUND: The current tumor-node-metastasis staging system for the pancreas does not incorporate the number of lymph nodes (LNs) with metastasis. METHODS: Among 1649 pancreaticoduodenectomies, 227 stringently defined pancreatic ductal adenocarcinomas (PDACs) that had undergone a specific approach of LN harvesting were analyzed for the prognostic value of LN substaging protocols used for other gastrointestinal (GI) organs. RESULTS: The median number of LNs harvested was 18, and the median number of LNs with metastasis was 3. Lymph node metastasis was detected in 175 cases (77 %). The number of LNs involved correlated significantly with clinical outcome. When cases were substaged with the protocol already in use for the upper GI organs (N0: no metastasis, N1: metastasis to 1-2 LNs; N2: metastasis to ≥3 LNs), the median overall survival times were 35, 21, and 18 months, and the respective 3-year survival rates were 46, 34, and 20 % (p = 0.004). Analysis of the Surveillance, Epidemiology and End Results (SEER) database also confirmed the survival differences between these substages (median overall survival times of 23, 15, and 14 months and respective 3-year survival rates of 37, 22, and 18 %; p < 0.0001). The substaging protocol for the lower GI organs (N0: no metastasis; N1: metastasis to 1-3 LNs; N2: metastasis to ≥4 LNs) also was significant, with median overall survival times of 35, 21, 18 months and respective 3-year survival rates of 46, 26, and 23 %; p = 0.009). The association between higher N stage and shorter survival persisted with multivariate modeling for both protocols, although the prognostic value of the upper GI protocol appeared to be slightly stronger according to the Akaike Information Criterion method. CONCLUSION: In conclusion, with proper LN harvesting, the LN metastasis rate in PDACs is very high (77 %). Substaging of LN metastasis has significant prognostic value and needs to be considered in the N staging of PDACs. The protocol already in use for other upper GI tract organs, which currently also is proven significant for ampulla, would be preferable, although the lower GI tract protocol also is applicable.

RESUMO

BACKGROUND: Current nodal staging (N-staging) of ampullary carcinoma in the TNM staging system distinguishes between node-negative (N0) and node-positive (N1) disease but does not consider the metastatic lymph node (LN) number. METHODS: Overall, 313 patients who underwent pancreatoduodenectomy for ampullary adenocarcinoma were categorized as N0, N1 (1-2 metastatic LNs), or N2 (≥3 metastatic LNs), as proposed by Kang et al. Clinicopathological features and overall survival (OS) of the three groups were compared. RESULTS: The median number of LNs examined was 11, and LN metastasis was present in 142 cases (45 %). When LN-positive cases were re-classified according to the proposed staging system, 82 were N1 (26 %) and 60 were N2 (19 %). There was a significant correlation between proposed N-stage and lymphovascular invasion, perineural invasion, increased tumor size (each p < 0.001), and surgical margin positivity (p = 0.001). The median OS in LN-negative cases was significantly longer than that in LN-positive cases (107.5 vs. 32 months; p < 0.001). Patients with N1 and N2 disease had median survivals of 40 and 24.5 months, respectively (p < 0.0001). In addition, 1-, 3-, and 5-year survivals were 88, 76, 62 %, respectively, for N0; 90, 55, 31.5 %, respectively, for N1; and 68, 34, 30 %, respectively for N2 (p < 0.001). Even with multivariate modeling, the association between higher proposed N stage and shorter survival persisted (hazard ratio 1.6 for N1 and 1.9 for N2; p = 0.018). CONCLUSIONS: Classification of nodal status in ampullary carcinomas based on the number of metastatic LNs has a significant prognostic value. A revised N-staging classification system should be incorporated into the TNM staging of ampullary cancers.

RESUMO

OBJECTIVE: To compare academic outcomes between children with orofacial cleft (OFC) and children without major birth defects. DESIGN AND SETTING: In 2007-2008, we mailed questionnaires to a random sample of mothers of school-aged children with OFC and mothers of children without major birth defects (comparison group). The questionnaire included Likert-scale, closed-ended, and open-ended questions from validated instruments. We conducted bivariate and multivariable analyses on parent-reported educational outcomes and bivariate analyses on parent-reported presence of related medical conditions between children with isolated OFC and unaffected children. PATIENTS/PARTICIPANTS: A random sample of 504 parents of children with OFCs born 1996-2002 (age 5-12 years) were identified by the North Carolina Birth Defects Monitoring Program. A random sample of 504 parents of children without birth defects born 1996-2002 was selected from North Carolina birth certificates. Of the 289 (28.7%) respondents, we analyzed 112 children with isolated OFC and 138 unaffected children. MAIN OUTCOME MEASURES: Letter grades, school days missed, and grade retention. RESULTS: Parents of children with isolated OFC reported more developmental disabilities and hearing and speech problems among their children than comparison parents. Children with isolated OFC were more likely to receive lower grades and miss more school days than unaffected children. Because of the low response rate, results should be interpreted cautiously. CONCLUSION: Children with isolated OFC may have poorer academic outcomes during elementary school than their unaffected peers. Future studies are needed to confirm these results and determine whether these differences persist in later grades.

RESUMO

BACKGROUND: Loss of fertility has been reported as an important concern of reproductive age women diagnosed with cancer. The Furthering Understanding of Cancer, Health, and Survivorship In Adult (FUCHSIA) Women's Study examines how cancer treatment affects the fertility of cancer survivors who were diagnosed during their reproductive years. In this paper we discuss the process of developing and pilot testing the FUCHSIA computer assisted telephone interview (CATI). METHODS: The CATI was developed in several phases and pilot tested twice to evaluate several aspects of the instrument including question sequencing, understandability of the questions, and women's comfort with certain questions. Participants were recruited from cancer and infertility support groups and study team contacts. RESULTS: Fifty-two women were recruited and participated in the first pilot. The participants had a mean age of 31.5 years, 17.3% had cancer, and 38.5% experienced a period of infertility. Twenty-four women participated in the second pilot with similar representation. CONCLUSIONS: The collection of detailed information on reproductive outcomes with the CATI may improve the understanding of how cancer treatment during the reproductive years affects female fertility. The pilot studies provided important information to improve the CATI before the full study. Our comprehensive recruitment strategy allowed us to interview a diverse group of women to ensure that questions and answer choices were easily interpreted, check complicated skip patterns and the flow of questions, and evaluate the length of the interview. This experience can be used to help inform others in what steps can be useful for developing telephone interviews for research studies.

RESUMO

BACKGROUND: The goal of this study was to describe in-hospital and long-term mortality after single-stage repair of truncus arteriosus communis (TAC) and explore factors associated with these outcomes. METHODS: This was a cohort study of consecutive patients undergoing single-stage TAC repair between 1982 and 2011 reported to the Pediatric Cardiac Care Consortium registry. In-hospital mortality was obtained for the entire cohort from registry records. Long-term mortality was obtained for patients with available identifiers by matching with the National Death Index through 2020. Kaplan-Meier survival estimates were created for up to 30 years after discharge. Cox regression models estimated hazard ratios for the associations with potential risk factors. RESULTS: A total of 647 patients (51% male) underwent single-stage TAC repair at a median age of 18 days; 53% had type I TAC, 13% had interrupted aortic arch, and 10% underwent concomitant truncal valve surgery. Of these, 486 (75%) patients survived to hospital discharge. After discharge, 215 patients had identifiers for tracking long-term outcomes; 30-year survival was 78%. Concomitant truncal valve surgery at the index procedure was associated with increased in-hospital and 30-year mortality. Concomitant interrupted aortic arch repair was not associated with increased in-hospital or 30-year mortality. CONCLUSIONS: Concomitant truncal valve surgery but not interrupted aortic arch was associated with higher in-hospital and long-term mortality. Careful consideration of the need and timing for truncal valve intervention may improve TAC outcomes.
