RESUMO

The rates and patterns of somatic mutation in normal tissues are largely unknown outside of humans1-7. Comparative analyses can shed light on the diversity of mutagenesis across species, and on long-standing hypotheses about the evolution of somatic mutation rates and their role in cancer and ageing. Here we performed whole-genome sequencing of 208 intestinal crypts from 56 individuals to study the landscape of somatic mutation across 16 mammalian species. We found that somatic mutagenesis was dominated by seemingly endogenous mutational processes in all species, including 5-methylcytosine deamination and oxidative damage. With some differences, mutational signatures in other species resembled those described in humans8, although the relative contribution of each signature varied across species. Notably, the somatic mutation rate per year varied greatly across species and exhibited a strong inverse relationship with species lifespan, with no other life-history trait studied showing a comparable association. Despite widely different life histories among the species we examined-including variation of around 30-fold in lifespan and around 40,000-fold in body mass-the somatic mutation burden at the end of lifespan varied only by a factor of around 3. These data unveil common mutational processes across mammals, and suggest that somatic mutation rates are evolutionarily constrained and may be a contributing factor in ageing.

RESUMO

The mountain chicken frog (Leptodactylus fallax) is a critically endangered species highly reliant on ex situ conservation programs. In captivity, cholelithiasis has been reported during clinical examinations using diagnostic imaging and observed during postmortem examinations. Some individuals have presented with nonspecific clinical signs potentially associated with this condition, but little is known about its clinical relevance. A retrospective evaluation of ultrasonographic (n = 139) and radiographic (n = 156) images and histopathology samples (n = 32) obtained between 2014 and 2020 from 133 individuals was performed. An ultrasound scoring system was developed to evaluate changes in the gallbladder, with 38% (53/139) of the images showing abnormal contents. Gallbladder distension appeared associated with these findings (generalized estimating equation model, P < 0.001). In contrast, radiography proved to have low overall sensitivity (48%) when compared to ultrasonography for identifying abnormal gallbladder contents. A weak level of agreement (Cohen's kappa = 0.535) was observed between the imaging modalities. Histologically, cholecystitis was present in 86% (12/14) of the individuals, thickening of the gallbladder wall in 71% (10/14), and intrahepatic cholangitis in 90% (18/20). There was no evidence of cholestasis in any of the affected individuals. A significant difference was observed in the hepatic melanomacrophage density between animals with and without cholelithiasis (Welch two-sample t test, P < 0.001). This study provides an overview on the use of diagnostic imaging modalities to evaluate cholelithiasis and proposes a convenient ultrasound score to standardize monitoring of the condition in L. fallax. It is also the first systematic review of histopathological changes associated with cholelithiasis in this species.

RESUMO

There is evidence that zoo visitor presence can influence the behaviour and, in some cases, adrenal response of zoo animals, and can sometimes compromise animal welfare. In some laboratory studies, significantly more primate births have been reported on weekends, when fewer people are working there, compared with weekdays when staffing levels are at their highest. Here, we investigate whether there is evidence of a "weekend effect" on births in zoo animals as a result of visitor numbers. Unlike laboratories, zoos are typically busier with visitors on weekends than on weekdays, although staffing levels remain fairly consistent across days of the week. If zoo animal parturition is sensitive to human presence, then fewer births would be expected on weekends compared with weekdays. We tested this using birth data and visitor numbers on the entrance gate from zoo records across 16 species representing artiodactyls, perissodactyls, carnivores and primates at four British zoos, to see whether there is an association between mean daily birth rates and average visitor numbers. We predict that, if there is a visitor effect, daily births should be lower on weekends than weekdays and should correlate with mean daily visitor numbers. Results showed that births for all 16 species were randomly distributed through the week, and there was no significant decline in births on weekends. We conclude that the "weekend effect", if such a thing exists, does not appear to be a feature of zoo births, suggesting that elevated weekend visitor numbers are not sufficiently stressful to trigger delayed parturition.

RESUMO

PURPOSE: Clinical trials in oncology evaluating the effects of patient-reported outcomes (PRO) collection have found that monitoring of symptoms with PROs is associated with improved clinical care through reduced acute care utilization and decreased patient symptom burden. This educational review will evaluate strategies for systematic PRO integration into everyday oncology clinical practice. METHODS: We outline key considerations for using PROs in clinical practice, highlighting evidence from published studies. We also discuss the benefits and challenges of PRO implementation in oncology. RESULTS: Implementing PRO collection in clinical practice can improve care delivery and facilitate patient-centered clinical research. Considerations for using PROs in clinical practice include choice of instrument, method of delivery, and frequency of query. Challenges with implementing systematic PRO collection include the costs and resources needed for implementation, impact on clinical workflow, and controlling/monitoring physician burnout. CONCLUSIONS: While challenges exist in terms of financial resources and staff participation/burnout, patient-reported outcomes in clinical practice provide a number of benefits, including symptom monitoring, clinical research, and potential real-time personalized clinical-decision support.

RESUMO

This study sought to investigate the feasibility and acceptability of a flexible psychotherapeutic approach - the Method of Levels (MOL) - in an acute mental health inpatient setting. A multi methods approach was used. The feasibility of implementation was investigated by examining the referral rate and the attendance patterns of participants. The acceptability of MOL was explored using a thematic analysis of participant interviews and by recording attendance patterns of participants. Inpatient staff consistently referred patients and the majority of eligible people accepted invitations for therapy. Thematic analysis of peoples' experiences of the therapy generated themes that described participants' experiences of MOL in contrast to routine NHS care, having spent meaningful time with the therapist, and having gained something from the session. The referral rate and uptake of MOL therapy indicates that the resource was appropriate for the setting and acceptable to most participants. Qualitative analyses indicated that participants were comfortable with the therapists' approach, felt understood, and there was a meaningful quality to their interaction. Participants also valued the opportunity to reflect and generate new perspectives of their difficulties. Further research is required to determine the effectiveness of the approach and its translational value beyond this pilot investigation.

RESUMO

Background: This study examined receipt of guideline-concordant care (GCC) according to evidence-based treatment guidelines and quality measures and specific types of treatment among older women with breast cancer. Patients and Methods: A total of 142,433 patients aged ≥66 years diagnosed with stage I-III breast cancer between 2007 and 2011 were identified in the SEER-Medicare linked database. Algorithms considering cancer characteristics and the appropriate course of care as per guidelines versus actual care received determined receipt of GCC. Multivariable logistic regression estimated the likelihood of GCC and specific types of treatment for women aged ≥75 versus 66 to 74 years. Results: Overall, 39.7% of patients received GCC. Patients diagnosed at stage II or III, with certain preexisting conditions, and of nonwhite race were less likely to receive GCC. Patients with hormone-negative tumors, higher grade tumors, and greater access to oncology care resources were more likely to receive GCC. Patients aged ≥75 years were approximately 40% less likely to receive GCC or adjuvant endocrine therapy, 78% less likely to have any surgery, 61% less likely to have chemotherapy, and about half as likely to have radiation therapy than those aged 66 to 74 years. Conclusions: Fewer than half of older women with breast cancer received GCC, with the lowest rates observed among the oldest age groups, racial/ethnic minorities, and women with later-stage cancers. However, patients with more aggressive tumor characteristics and greater access to oncology resources were more likely to receive GCC. Considering that older women have the highest incidence of breast cancer and that many are diagnosed at stages requiring more aggressive treatment, efforts to increase rates of earlier stage diagnosis and the development of less toxic treatments could help improve GCC and survival while preserving quality of life.

RESUMO

PURPOSE: While the use of electronic patient-reported outcomes (ePROs) in routine clinical practice is increasing, barriers to patient engagement limit adoption. Studies have focused on technology access as a key barrier, yet other characteristics may also confound readiness to use ePROs including patients' confidence in using technology and confidence in asking clinicians questions. METHODS: To assess readiness to use ePROs, adult patients from six US-based health systems who started a new oncology treatment or underwent a cancer-directed surgery were invited to complete a survey that assessed access to and confidence in the use of technology, ease of asking clinicians questions about health, and symptom management self-efficacy. Multivariable ordinal logistic regression models were fit to assess the association between technology confidence, ease of asking questions, and symptom management self-efficacy. RESULTS: We contacted 3,212 individuals, and 1,043 (33%) responded. The median age was 63 years, 68% were female, and 75% reported having access to patient portals. Over 80% had two or more electronic devices. Most patients reported high technology confidence, higher ease of asking clinicians questions, and high symptom management self-efficacy (n = 692; 66%). Patients with high technology confidence also reported higher ease of asking nurses about their health (adjusted odds ratio [AOR], 4.58 [95% CI, 2.36 to 8.87]; P ≤ .001). Those who reported higher ease of asking nurses questions were more likely to report higher confidence in managing symptoms (AOR, 30.54 [95% CI, 12.91 to 72.30]; P ≤ .001). CONCLUSION: Patient readiness to use ePROs likely depends on multiple factors, including technology and communication confidence, and symptom management self-efficacy. Future studies should assess interventions to address these factors.

RESUMO

Background: Electronic patient-reported outcome (ePRO)-based symptom management improves cancer patients' outcomes. However, implementation of ePROs is challenging, requiring technical resources for integration into clinical systems, substantial buy-in from clinicians and patients, novel workflows to support between-visit symptom management, and institutional investment. Methods: The SIMPRO Research Consortium developed eSyM, an electronic health record-integrated, ePRO-based symptom management program for medical oncology and surgery patients and deployed it at six cancer centers between August 2019 and April 2022 in a type II hybrid effectiveness-implementation cluster randomized stepped-wedge study. Sites documented implementation strategies monthly using REDCap, itemized them using the Expert Recommendations for Implementation Change (ERIC) list and mapped their target barriers using the Consolidated Framework for Implementation Research (CFIR) to inform eSyM program enhancement, facilitate inter-consortium knowledge sharing and guide future deployment efforts. Results: We documented 226 implementation strategies: 35 'foundational' strategies were applied consortium-wide by the coordinating center and 191 other strategies were developed by individual sites. We consolidated these 191 site-developed strategies into 64 unique strategies (i.e., removed duplicates) and classified the remainder as either 'universal', consistently used by multiple sites (N=29), or 'adaptive', used only by individual sites (N=35). Universal strategies were perceived as having the highest impact; they addressed eSyM clinical preparation, training, engagement of patients/clinicians, and program evaluation. Across all documented SIMPRO strategies, 44 of the 73 ERIC strategies were addressed and all 5 CFIR barriers were addressed. Conclusion: Methodical collection of theory-based implementation strategies fostered the identification of universal, high-impact strategies that facilitated adoption of a novel care-delivery intervention by patients, clinicians, and institutions. Attention to the high-impact strategies identified in this project could support implementation of ePROs as a component of routine cancer care at other institutions.

RESUMO

BACKGROUND: Optimal methods for deploying electronic patient-reported outcomes (ePROs) to manage symptoms in routine oncologic practice remain uncertain. The eSyM symptom management program asks chemotherapy and surgery patients to self-report 12 symptoms regularly. Feedback from nurses and patients led to changing the recall period from the past 7 days to the past 24 hours. METHODS: Using questionnaires submitted during the 16-weeks surrounding the recall period change, we assessed the likelihood of reporting a severe, or a moderate-severe, symptom across all 12 symptoms and separately for the 5 most prevalent symptoms. Interrupted time series analyses modeled the effects of the change using generalized linear mixed-effects models. Surgery and chemotherapy cohorts were analyzed separately. Study-wide effects were estimated using a meta-analysis method. RESULTS: In total, 1,692 patients from 6 institutions submitted 7,823 eSyM assessments during the 16-weeks surrounding the recall period change. Shortening the recall period was associated with lower odds of severe symptom reporting in the surgery cohort (OR 0.65; 95% CI 0.46 to 0.93; p = .02) and lower odds of moderate-severe symptom reporting in the chemotherapy cohort (OR 0.83, 95% CI 0.71 to 0.97; p = .02). Among the most prevalent symptoms, 24-hour recall was associated with lower rate of reporting post-operative constipation, but no differences in reporting rates for other symptoms. CONCLUSION: A shorter recall period was associated with a reduction in the proportion of patients reporting moderate-severe symptoms. The optimal recall period may vary depending on whether ePROs are collected for active symptom management, as a clinical trial endpoint, or another purpose. (Clinicaltrails.gov (NCT03850912).

RESUMO

INTRODUCTION: The role of internal mammary nodal irradiation (IMNI) as a component of regional nodal radiotherapy is a controversial issue in breast radiation oncology with conflicting results presented in recent landmark trials. We thus created a meta-analysis of available data to better ascertain the potential benefit of IMNI. We hypothesize that with the increased power available within a meta-analysis, IMNI will prove to improve overall survival (OS) in breast cancer. METHODS: Literature search was conducted for prospective studies comparing IMNI to no IMNI. Primary endpoint was OS and secondary endpoints included local recurrence, regional recurrence, disease-free survival (DFS), breast cancer mortality (BCM), distant metastasis-free survival (DMFS), grade 2+ skin toxicity, cardiac events, and pneumonitis events. Subgroup analyses were performed for tumor location (medial/central vs. lateral), and nodal status (pN+ vs. pN0). Fixed-effect model was used if there was no heterogeneity, random-effects model otherwise. RESULTS: Four studies with a total of 5258 patients (IMNI: n=2592; control: n=2666) were included in the study. Pooled results showed IMNI significantly improved OS for all-comers (hazard ratio [HR]=0.89; 95% CI 0.81-0.97; P =0.008), as well as subgroups of pN+ with medial/central tumor location (HR=0.84; 95% CI 0.73-0.96; P =0.01) and pN+ with lateral tumor location (HR=0.87; 95% CI 0.77-0.99; P =0.04). There was no significant difference in OS for subgroups of pN0 and medial/central tumor location. There was no difference in local recurrence, but regional recurrence was significantly improved ( P =0.04). Endpoints of DFS (HR 0.91, 95% CI 0.84-0.99 P =0.03), BCM (HR 0.87, 95% CI 0.77-0.98, P =0.03), and DMFS (HR=0.87; 95% CI, 0.78-0.98; P =0.02) were all improved with IMNI. Grade 2+ skin toxicity, cardiac events and pneumonitis events were not significantly different between patient in the IMNI and no IMNI groups. CONCLUSION: Inclusion of IMN irradiation improves OS, DFS, BCM, and DMFS in breast cancer. Largest effect on OS was noted in the subgroup of patients with pN+ and medial/central tumor location.

RESUMO

BACKGROUND: Patient and public involvement (PPI) in healthcare professional education is important, yet publications often provide insufficient detail about the types of involvement patients undertake and the level of autonomy that they have. This study details the factors that promote or hinder PPI within a university healthcare professional education setting and the types of activities members conducted. METHODS: PPI activities were described and mapped against a framework for PPI in healthcare professional education. Semi-structured interviews with PPI group members explored the motivators, enablers and barriers that influence involvement. FINDINGS: The framework highlighted that the PPI group were involved in a range of activities, yet they received limited training for their role and were infrequently involved in planning the activities. When interviewed, PPI members did not consider that these factors were the important promoters or barriers to involvement, instead emphasising five themes: (1) their individual characteristics, (2) factors relating to the university organisation, (3) relationships between themselves, faculty and students, (4) time in their role and (5) evidence of their impact. DISCUSSION AND CONCLUSION: Supporting PPI members whilst working, rather than provision of formal training was considered most empowering for group members. This was mediated through having enough time in their role to develop supportive relationships with faculty, which in turn promoted self-confidence and increased autonomy. This should be considered when making PPI appointments. Small changes in processes during education planning can make it easier for PPI members to bring their own agenda forward and promote equity during education decision making.

RESUMO

BACKGROUND: The prospective surveillance model (PSM) is an evidence-based rehabilitation care delivery model that facilitates functional screening and intervention for individuals undergoing cancer treatment. While PSM is empirically validated and feasible in practice, implementation into cancer care delivery has languished. The purpose of this manuscript is to characterize the barriers and facilitators to implementing PSM in a breast cancer center and to share policy and process outcomes that have sustained the model in practice. METHODS: The PSM implementation was undertaken as a quality improvement initiative of our cancer center. We retrospectively assessed barriers to implementation and define those according to the Consolidated Framework for Implementation Research (CFIR). Implementation strategies are defined based on the Expert Recommendations for Implementation Change (ERIC) taxonomy. Breast center policy changes and stakeholder-reported process improvement outcomes at the clinic and system level are described. RESULTS: PSM implementation facilitation was driven primarily by adapting the model to align with the cancer center workflow, engaging interdisciplinary stakeholders as program champions, enhancing knowledge and awareness among cancer care providers, and changing infrastructure to support the model. System and clinic-level policy and process changes included the development of clinical pathways, EHR order sets and automated referrals, new staffing models, and adapted clinical workflows. CONCLUSION: Our report provides insight on implementing the PSM at a single institution in a cancer care delivery setting. Successful implementation strategies addressed individual, clinic, and system-level barriers and facilitated process and policy changes that have enabled PSM sustainment. Improving integration of rehabilitation services into oncology care has significant implications for survivorship care by enhancing proactive management of functional morbidity. IMPLICATIONS FOR CANCER SURVIVORS: Improving integration of rehabilitation services into oncology care has significant implications for survivorship care by enhancing proactive management of functional morbidity.

RESUMO

Introduction: Adverse childhood experiences (ACEs) are associated with increased cancer risk. ACEs may affect this risk in a variety of ways, including cancer screening compliance. ACEs can contribute to mistrust in the medical profession, inhibit patient-provider relationships and cause at-risk individuals to miss critical access points to preventive services. Protective factors may play an important role in mitigating ACE-related consequences by supporting resiliency. Purpose: This study assesses the associations between ACEs, protective factors, patient-provider relationships, stage of cancer at diagnosis, and cancer screening behaviors for West Virginia (WV) cervical cancer survivors. Methods: WV cervical cancer survivors diagnosed between 2000 and 2020 were mailed a survey which included questions on demographic information and cancer screening behaviors, alongside three scales to measure depth of patient-provider relationships, ACEs, and protective factors. Results: Ninety participants completed the survey. ACEs were associated with weaker patient-provider relationships (p < .01) and fewer protective factors (p < .01). More protective factors were associated with stronger patient-provider relationships (p < .01), earlier stage of cancer at diagnosis (p < .05) and positive cancer screening behaviors. Positive cancer screening behaviors were associated with deeper patient-provider relationships (p < .05). A statistically significant model (p = .004) using ACE and resilience scores was able to account for 13% of the explained variability in depth of patient-provider relationships. Implications: These findings suggest an important interplay between ACEs, protective factors, and patient-provider relationships on cancer screening behaviors. Future studies should consider these variables in different populations. In addition, interventions focused on enhancing patient-provider relationships and supporting acquisition of protective factors should be considered.

RESUMO

Objective: Adequate physician-patient communication about cancer recurrence is vital to quality of life and to informed decision-making related to survivorship care. The current study was guided by a cognitive-affective framework to examine communication with family and physicians about breast cancer recurrence risk. Methods: A survey of recently-diagnosed, early-stage breast cancer patients in Appalachia investigated physician-patient and familial communication about breast cancer recurrence risk. Results: Over 30% of participants reported not talking to family or physicians about breast cancer recurrence risk. Younger patients reported more conversations, and speaking with physicians was associated with greater perception risk factors associated with recurrence risk. Greater worry about recurrence was associated with more communication with family and plans to talk to family, physicians, and friends about recurrence risk in the future. Conclusion: Additional supports for patients and physicians are needed to improve understanding of breast cancer recurrence risk and risk factors for recurrence. Innovation: Family communication about breast cancer recurrence risk is understudied. The combination of physician and family communication adds novelty to our analysis.

RESUMO

BACKGROUND/OBJECTIVE: Cavity shave margins (CSMs) decrease rate of positive margins and need for re-excision. Recurrence data following breast-conserving surgery (BCS) are not always available in large cancer registries. We sought to define our recurrence and survival data in BCS with routine excision of CSMs. METHODS: A single institution, 10-year retrospective review of breast cancer patients who underwent BCS with routine CSMs was conducted. Cavity shave margin technique was standard. Cox proportional hazard analyses and the Kaplan-Meier method were used to estimate recurrence and survival. RESULTS: Breast-conserving surgery with CSM was performed in 839 patients. Re-excision rate to achieve negative margins was 8.5%. Fifty-two patients (75%) underwent margin re-excision vs 18 patients (25%) underwent salvage mastectomy. Positive margin rate stratified by tumor histology was highest for invasive lobular carcinoma followed by mixed invasive ductal carcinoma (IDC) and ductal carcinoma in situ (DCIS), followed by pure DCIS and lowest for IDC. Length of follow-up was (4.7 ± 2.6, years). Overall recurrence rate (locoregional and systemic) was 4.3%: highest in patients with negative lumpectomy margin but positive CSM (L-S+ = 15%) followed by positive lumpectomy and CSMs (L+S+ = 14%), followed by patients with positive lumpectomy margin but negative CSMs (L+S- = 13%) and lowest for negative lumpectomy and CSM (L-S- = 5%), (P = .0008). There was no difference in 5-year breast cancer-specific survival between the 4 subgroups: 96% for L-S-, 86.7% L-S+, 94.7% L+S+ and 90% L+S- (P = .094). CONCLUSIONS: Recurrence following BCS with CSMs can be stratified based on both lumpectomy and cavity shave margin positivity. Routine excision of CSMs allows identification of these patient subsets.

RESUMO

Cancer survivorship is complex and varies by individual, disease type, geographic area, and socioeconomic resources. As cancer treatments and survival improves, the survivorship population continues to grow. Communication between oncologists, patients, health care providers, patient advocates, and other stakeholders is critical to improved outcomes in cancer survivors. Important areas of study relate to improving the quality of life in survivors and include health promotion, psychosocial distress, and financial toxicity of cancer treatment. As survivorship begins at diagnosis, cancer programs must incorporate survivorship treatment goals into the care plan initially to positively effect the quality of life and improve health outcomes.

RESUMO

Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory disorder of the arterial wall muscular layer which can lead to arterial stenosis, occlusion, and dissection. Clinical presentations of FMD vary depending on the arterial territories involved, often leading to diagnostic challenges. This case report describes an exceptionally unusual presentation of FMD, not previously described, affecting a previously fit and well 37-year-old female presenting with bilateral renal infarction, sequential vertebral artery dissections, mesenteric ischaemia, and the requirement for continued renal replacement. This report highlights how unusual presentations of FMD can mask the underlying diagnosis. Early consideration of FMD in a differential diagnosis can guide an effective management strategy, including appropriate imaging and multi-speciality involvement.

RESUMO

BACKGROUND: Many cancer patients experience high symptom burden. Healthcare in the USA is reactive, not proactive, and doctor-patient communication is often suboptimal. As a result, symptomatic patients may suffer between clinic visits. In research settings, systematic assessment of electronic patient-reported outcomes (ePROs), coupled with clinical responses to severe symptoms, has eased this symptom burden, improved health-related quality of life, reduced acute care needs, and extended survival. Implementing ePRO-based symptom management programs in routine care is challenging. To study methods to overcome the implementation gap and improve symptom control for cancer patients, the National Cancer Institute created the Cancer-Moonshot funded Improving the Management of symPtoms during And following Cancer Treatment (IMPACT) Consortium. METHODS: Symptom Management IMplementation of Patient Reported Outcomes in Oncology (SIMPRO) is one of three research centers that make up the IMPACT Consortium. SIMPRO, a multi-disciplinary team of investigators from six US health systems, seeks to develop, test, and integrate an electronic symptom management program (eSyM) for medical oncology and surgery patients into the Epic electronic health record (EHR) system and associated patient portal. eSyM supports real-time symptom tracking for patients, automated clinician alerts for severe symptoms, and specialized reports to facilitate population management. To rigorously evaluate its impact, eSyM is deployed through a pragmatic stepped wedge cluster-randomized trial. The primary study outcome is the occurrence of an emergency department treat-and-release event within 30 days of starting chemotherapy or being discharged following surgery. Secondary outcomes include hospitalization rates, chemotherapy use (time to initiation and duration of therapy), and patient quality of life and satisfaction. As a type II hybrid effectiveness-implementation study, facilitators and barriers to implementation are assessed throughout the project. DISCUSSION: Creating and deploying eSyM requires collaboration between dozens of staff across diverse health systems, dedicated engagement of patient advocates, and robust support from Epic. This trial will evaluate eSyM in routine care settings across academic and community-based healthcare systems serving patients in rural and metropolitan locations. This trial's pragmatic design will promote generalizable results about the uptake, acceptability, and impact of an EHR-integrated, ePRO-based symptom management program.

RESUMO

Bluetongue virus (BTV) and African horse sickness virus (AHSV) cause economically important diseases that are currently exotic to the United Kingdom (UK), but have significant potential for introduction and onward transmission. Given the susceptibility of animals kept in zoo collections to vector-borne diseases, a qualitative risk assessment for the introduction of BTV and AHSV to ZSL London Zoo was performed. Risk pathways for each virus were identified and assessed using published literature, animal import data and outputs from epidemiological models. Direct imports of infected animals, as well as wind-borne infected Culicoides, were considered as routes of incursion. The proximity of ongoing disease events in mainland Europe and proven capability of transmission to the UK places ZSL London Zoo at higher risk of BTV release and exposure (estimated as low to medium) than AHSV (estimated as very low to low). The recent long-range expansion of AHSV into Thailand from southern Africa highlights the need for vector competence studies of Palearctic Culicoides for AHSV to assess the risk of transmission in this region.

RESUMO

Atypical ductal hyperplasia (ADH) and atypical lobular hyperplasia (ALH) of the breast are premalignant lesions. Although the literature on ADH and ALH as a whole is well-developed, research on ADH and ALH incidentally discovered during breast reduction is less robust. METHODS: In this study, 355 patients undergoing bilateral reduction mammoplasty at West Virginia University were retrospectively reviewed. A variety of demographic and clinicopathologic variables were collected for each patient, and the incidence of atypical hyperplasia was calculated. Four patients (1.13%) were found to have atypical hyperplasia, three ALH, and one ADH, which is within the range reported in the literature. For patients incidentally found to have atypical hyperplasia, an in-depth analysis of postoperative management was performed. RESULTS: Of the four patients with atypical hyperplasia, three were referred to a cancer center, and one patient followed only with plastic surgery. The three patients who were referred to a cancer center saw a breast surgeon, whereas the patient followed only by plastic surgery did not. None of the four patients received anti-estrogen therapy, but each patient who followed with a cancer center was offered treatment and declined. CONCLUSIONS: As a relatively uncommon finding with complex management guidelines, atypical hyperplasia discovered on breast reduction should be referred to a cancer center for long-term follow-up and management when possible. Further research is needed to assess if the management of atypical hyperplasia discovered incidentally after routine reduction should mimic treatment of atypical hyperplasia found after biopsy for suspicion of malignancy.
