Design and implementation of community consultation for research conducted under exception from informed consent regulations for the PreVent and the PreVent 2 trials: Changes over time and during the COVID-19 pandemic.

INTRODUCTION: Emergency clinical research has played an important role in improving outcomes for acutely ill patients. This is due in part to regulatory measures that allow Exception From Informed Consent (EFIC) trials. The Food and Drug Administration (FDA) requires sponsor-investigators to engage in community consultation and public disclosure activities prior to initiating an Exception From Informed Consent trial. Various approaches to community consultation and public disclosure have been described and adapted to local contexts and Institutional Review Board (IRB) interpretations. The COVID-19 pandemic has precluded the ability to engage local communities through direct, in-person public venues, requiring research teams to find alternative ways to inform communities about emergency research. METHODS: The PreVent and PreVent 2 studies were two Exception From Informed Consent trials of emergency endotracheal intubation, conducted in one geographic location for the PreVent Study and in two geographic locations for the PreVent 2 Study. During the period of the two studies, there was a substantial shift in the methodological approach spanning across the periods before and after the pandemic from telephone, to in-person, to virtual settings. RESULTS: During the 10 years of implementation of Exception From Informed Consent activities for the two PreVent trials, there was overall favorable public support for the concept of Exception From Informed Consent trials and for the importance of emergency clinical research. Community concerns were few and also did not differ much by method of contact. Attendance was higher with the implementation of virtual technology to reach members of the community, and overall feedback was more positive compared with telephone contacts or in-person events. However, the proportion of survey responses received after completion of the remote, live event was substantially lower, with a greater proportion of respondents having higher education levels. This suggests less active engagement after completion of the synchronous activity and potentially higher selection bias among respondents. Importantly, we found that engagement with local community leaders was a key component to develop appropriate plans to connect with the public. CONCLUSION: The PreVent experience illustrated operational advantages and disadvantages to community consultation conducted primarily by telephone, in-person events, or online activities. Approaches to enhance community acceptance included partnering with community leaders to optimize the communication strategies and trust building with the involvement of Institutional Review Board representatives during community meetings. Researchers might need to pivot from in-person planning to virtual techniques while maintaining the ability to engage with the public with two-way communication approaches. Due to less active engagement, and potential for selection bias in the responders, further research is needed to address the costs and benefits of virtual community consultation and public disclosure activities compared to in-person events.

At-Home Saliva Sampling in Healthy Adults Using CandyCollect, a Lollipop-Inspired Device.

Respiratory infections are common in children, and there is a need for user-friendly collection methods. Here, we performed the first human subjects study using the CandyCollect device, a lollipop-inspired saliva collection device .We showed that the CandyCollect device can be used to collect salivary bacteria from healthy adults using Streptococcus mutans and Staphylococcus aureus as proof-of-concept commensal bacteria. We enrolled healthy adults in a nationwide (USA) remote study in which participants were sent study packages containing CandyCollect devices and traditional commercially available oral swabs and spit tubes. Participants sampled themselves at home, completed usability and user preference surveys, and mailed the samples back to our laboratory for analysis by qPCR. Our results showed that for participants in which a given bacterium (S. mutans or S. aureus) was detected in one or both of the commercially available methods (oral swab and/or spit tubes), CandyCollect devices had a 100% concordance with the positive result (n = 14 participants). Furthermore, the CandyCollect device was ranked the highest preference sampling method among the three sampling methods by 26 participants surveyed (combining survey results across two enrollment groups). We also showed that the CandyCollect device has a shelf life of up to 1 year at room temperature, a storage period that is convenient for clinics or patients to keep the CandyCollect device and use it any time. Taken together, we have demonstrated that the CandyCollect is a user-friendly saliva collection tool that has the potential to be incorporated into diagnostic assays in clinic visits and telemedicine.

'Maybe what I do know is wrong ': Reframing educator roles and professional development for teaching Indigenous health.

Settler colonisation continues to cause much damage across the globe. It has particularly impacted negatively on Indigenous peoples' health and wellbeing causing great inequity. Health professional education is a critical vehicle to assist in addressing this; however, non-Indigenous educators often feel unprepared and lack skill in this regard. In this qualitative study, 20 non-Indigenous nursing, physiotherapy and occupational therapy educators in Australia were interviewed about their experiences and perspectives of teaching Indigenous health. Findings from the inductive thematic analysis suggest educators require skill development to: identify their discomfort in teaching cultural safety; contextualise the sources of this discomfort and; reflect on how this understanding can improve their teaching. Additionally, educators require professional training to become practitioners of cultural humility and to be facilitators and colearners (rather than experts) of the Aboriginal-led curriculum. Of relevance to this is educator training in how to decentre non-Indigenous needs and perspectives. Educators can also renew their teaching practices by understanding what a dominant settler paradigm is, identifying if this is problematically present in their teaching and knowing how to remedy this. Crucial to improved cultural safety teaching is institutional support, which includes Indigenous leadership, institutional commitment, relevant policies, and well-designed professional development.

When I say Situation.

In this latest contribution to the 'When I say … ' series, Vass and Adams explore the pervasive impact of colonisation as an under-recognised and poorly addressed context of medical education.

homeRNA: A Self-Sampling Kit for the Collection of Peripheral Blood and Stabilization of RNA.

Gene expression analysis (e.g., targeted gene panels and transcriptomics) from whole blood can elucidate mechanisms of the immune function and aid in the discovery of biomarkers. Conventional venipuncture offers only a small snapshot of our broad immune landscape as immune responses may occur outside of the time and location parameters available for conventional venipuncture. A self-operated method that enables flexible sampling of liquid whole blood coupled with immediate stabilization of cellular RNA is instrumental in facilitating capture and preservation of acute or transient immune fluxes. To this end, we developed homeRNA, a kit for self-collection of peripheral blood (∼0.5 mL) and immediate stabilization of cellular RNA, using the Tasso-SST blood collection device with a specially designed stabilizer tube containing RNAlater. To assess the feasibility of homeRNA for self-collection and stabilization of whole blood RNA, we conducted a pilot study (n = 47 participants) in which we sent homeRNA to participants aged 21-69, located across 10 US states (94% successful blood collections, n = 61/65). Among participants who successfully collected blood, 93% reported no or minimal pain/discomfort using the kit (n = 39/42), and 79% reported very easy/somewhat easy stabilization protocol (n = 33/42). Total RNA yield from the stabilized samples ranged between 0.20 and 5.99 µg (mean = 1.51 µg), and all but one RNA integrity number values were above 7.0 (mean = 8.1), indicating limited RNA degradation. The results from this study demonstrate the self-collection and RNA stabilization of whole blood with homeRNA by participants themselves in their own home.

Educator perceptions on teaching Indigenous health: Racism, privilege and self-reflexivity.

INTRODUCTION: General practitioners (GPs) and family medicine clinicians should respond to Indigenous peoples' health needs. However, medical graduates feel underprepared for this work. The foundational elements of racism, white privilege and cultural self-reflexivity remain conspicuously absent from medical education in general practice programmes, despite inclusion in curriculum frameworks. This study explored the perception and experiences of Australian GP educators in teaching this content. METHODS: We undertook a qualitative study that gathered data through semi-structured interviews with GP educators (n = 12) at a medical school in Victoria, Australia. We utilised the Reflection learning domain of the Aboriginal and Torres Strait Islander Health Curriculum Framework to shape interview questions on racism, white privilege and cultural self-reflexivity. Data were analysed from constructivist and Critical Indigenous Theory paradigms to formulate key themes. RESULTS: General practitioner educators were challenged by Reflection content, struggled to articulate a refined pedagogy for provision of anti-racist, self-reflexive learning and felt poorly qualified to teach Indigenous health, articulating preference for delegation of teaching to Indigenous peoples. They simultaneously stated the importance of inclusion of Reflection teaching in general practice, alongside expressing beliefs that appeared to devalue its perceived relevance. Students were perceived as being either disinterested or incapable of Reflection learning, or conversely, more engaged than previous generations with these topics. DISCUSSION: The results call into question how skilled are GP educators to teach elements of Indigenous health education such as racism, white privilege and cultural self-reflexivity. Unskilled educators can reinforce colonialism in curricula, including through minimisation of content. Stronger anti-racist pedagogy is urgently required in medical education. Vital to this is active research on educator preparedness, evidence-based teaching models and accountable curriculum accreditation.

"Connection to Culture Is Like a Massive Lifeline": Yarning With Aboriginal Young People About Culture and Social and Emotional Wellbeing.

Culture is an important social and emotional wellbeing factor for Aboriginal peoples in Australia, particularly regarding recovery from colonization. However, little is understood about how culture and wellbeing interact for young urban Aboriginal people. This study used Yarning methods to explore experiences and perceptions of culture and wellbeing for young urban Aboriginal people in Narrm, Australia. Findings indicate that culture is experienced as connection, and that perceived connection or disconnection has an essential influence on the wellbeing of young people. Through sharing young people stories, a range of factors, including colonization, relationships, cultural knowledge, community support, and agency, were identified as affecting perceptions of connectedness, and therefore on wellbeing. Youth were able to develop strategies to increase connection and provided illuminating advice and suggestions for improving connection for future generations. This study thus contributes to efforts to improved understanding of Aboriginal perspectives about social and emotional wellbeing and culture.

Roadmap to recovery: Reporting on a research taskforce supporting Indigenous responses to COVID-19 in Australia.

In April 2020 a Group of Eight Taskforce was convened, consisting of over 100 researchers, to provide independent, research-based recommendations to the Commonwealth Government on a "Roadmap to Recovery" from COVID-19. The report covered issues ranging from pandemic control and relaxation of social distancing measures, to well-being and special considerations for vulnerable populations. Our work focused on the critical needs of Aboriginal and Torres Strait Islander communities; this paper presents an overview of our recommendations to the Roadmap report. In addressing the global challenges posed by pandemics for citizens around the world, Indigenous people are recognised as highly vulnerable. At the time of writing Australia's First Nations Peoples have been largely spared from COVID-19 in comparison to other Indigenous populations globally. Our recommendations emphasise self-determination and equitable needs-based funding to support Indigenous communities to recover from COVID-19, addressing persistent overcrowded housing, and a focus on workforce, especially for regional and remote communities. These latter two issues have been highlighted as major issues of risk for Indigenous communities in Australia It remains to be seen how governments across Australia take up these recommendations to support Indigenous peoples' health and healing journey through yet another, potentially catastrophic, health crisis.

Outcomes after Thrombectomy in Belfast: Mothership and Drip-and-Ship in the Real World.

BACKGROUND: Mechanical thrombectomy has revolutionised the treatment of acute ischaemic stroke due to large vessel occlusion. It is well recognised that patients are more likely to benefit when reperfusion happens quickly, however, there is uncertainty as to how best to deliver this service. OBJECTIVES: To compare outcomes of patients in Northern -Ireland who underwent thrombectomy via direct admission to the single endovascular centre (mothership [MS]) with those transferred from primary stroke centres (drip-and-ship [DS]). METHODS: Analysis was conducted on the records of all patients who underwent thrombectomy from January 2014 to December 2017 inclusive. The primary outcome measure was 3 months functional independence (modified Rankin Score [mRS] 0-2). Secondary outcome measures were full recovery (mRS 0) at 3 months, symptomatic intracranial haemorrhage (sICH) rates and mortality rates. RESULTS: Two hundred fourteen patients underwent thrombectomy (MS 124, DS 90). Patients in the MS group were older (median 73 vs. 70 years, p = 0.026), but there was no significant difference in baseline National Institutes of Health Stroke Scale (median 15 MS vs. 16.5 DS, p = 0.162) or thrombolysis rates (41.9% MS vs. 54.4% DS, p = 0.070) between the groups. Time from stroke onset to arrival at thrombectomy centre was shorter in the MS group (median 71 vs. 218 min, p < 0.001) but door to groin puncture time was shorter in the DS group (median 30 vs. 60 min, p < 0.001). There was no significant difference in 3 months functional independence (51.6% MS vs. 62.2% DS, p = 0.123), or in the secondary outcome measures of full recovery (21.8% MS vs. 12.2% DS, p = 0.071), sICH (MS 0.8%, DS 4.4%, p = 0.082) and mortality (MS 24.2%, DS 20.0%, p = 0.468). CONCLUSIONS: Our analysis showed similar outcomes after thrombectomy in the MS and DS groups. For patients potentially eligible for thrombectomy, rapid access to the endovascular centre is essential to optimise both the number of patients treated and the outcomes achieved.

Strengthening Aboriginal and Torres Strait Islander health policy: lessons from a case study of food and nutrition.

OBJECTIVE: To examine key factors influencing the prioritisation of food and nutrition in Aboriginal and Torres Strait Islander health policy during 1996-2015. DESIGN: A qualitative policy analysis case study was undertaken, combining document analysis with thematic analysis of key informant interviews. SETTING: Australia. PARTICIPANTS: Key actors involved in Aboriginal and Torres Strait Islander health policy between 1996 and 2015 (n 38). RESULTS: Prioritisation of food and nutrition in policy reduced over time. Several factors which may have impeded the prioritisation of nutrition were identified. These included lack of cohesion among the community of nutritionists, Aboriginal and Torres Strait Islander leaders and civil society actors advocating for nutrition; the absence of an institutional home for nutrition policy; and lack of consensus and a compelling policy narrative about how priority nutrition issues should be addressed. Political factors including ideology, dismantling of public health nutrition governance structures and missing the opportunities presented by 'policy windows' were also viewed as barriers to nutrition policy change. Finally, the complexity and multifaceted nature of nutrition as a policy problem and perceived lack of evidence-based solutions may also have constrained its prioritisation in Aboriginal and Torres Strait Islander health policy. CONCLUSIONS: Future advocacy should focus on embedding nutrition within holistic approaches to health and building a collective voice through advocacy coalitions with Aboriginal and Torres Strait Islander leadership. Strategic communication and seizing political opportunities may be as important as evidence for raising the priority of Aboriginal and Torres Strait Islander health issues.

Not just a policy; this is for real. An affirmative action policy to encourage Aboriginal and Torres Strait Islander peoples to seek employment in the health workforce.

Delivery of culturally safe healthcare is critical to ensuring access to high-quality care for indigenous people. A key component of this is for Aboriginal and Torres Strait Islander people to be participants in the health workforce. The proportion of indigenous people in the health workforce should at least equate to the proportion in the population served. We describe the development and implementation of a successful affirmative action employment policy at Monash Health, one of Australia's largest Academic Health Centres, and provide perspective on its adoption.

Indigenous Health Curriculum and Health Professional Learners: A Systematic Review.

Background: Globally, an estimated 370 million Indigenous peoples reside in more than 70 countries with these people commonly experiencing health care access inequity. Purpose: This systematic review aimed to examine the impact of Indigenous health care curriculum on entry-level health professional learners in preparation to deliver equitable health care. Methods: Seventeen articles were identified and analyzed for: context; study design; study measures, teaching and learning delivery mode, content and duration; positive and negative learner reactions; learning gained and article quality was assessed using the Medical Education Research Study Quality Instrument. Results: Most included studies described face-to-face delivery along with blended learning combining a placement in an Indigenous setting, stand-alone placements and digital learning. Descriptions of learning gained covered five domains: remembering, understanding, self-knowledge, perspective and application relating mostly to cultural awareness. Factors contributing to positive learner reactions included attitude, environment, educator skill, pedagogy and opportunities. Factors contributing to negative learner reactions included attitude and environment. Conclusions: There is a need to further explore how health professional graduates are prepared to work in Indigenous health and the appropriate measures to do this. There is opportunity to learn more about Indigenous health teaching and learning across learning domains, in mainstream clinical placements and in digital learning.

Superiority of 68Ga-DOTATATE over 18F-FDG and anatomic imaging in the detection of succinate dehydrogenase mutation (SDHx )-related pheochromocytoma and paraganglioma in the pediatric population.

PURPOSE: To evaluate and compare diagnostic performance of 68Ga-DOTA(0)-Tyr(3)-octreotate (68Ga-DOTATATE) with 18F-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography-computed tomography (PET/CT) and anatomic imaging using computed tomography and/or magnetic resonance (CT/MR) imaging in detection of SDHx-related pheochromocytomas and paragangliomas (PPGLs) in pediatric patients. METHODS: Nine pediatric patients (5:4, girls:boys; 14.6 ± 2.0 years) with an SDHx-related mutation (SDHB:SDHA:SDHD, n = 7:1:1) were included in this retrospective study. At the time of initial diagnosis, 7/9 patients had metastatic disease. They underwent CT/MR imaging along with PET/CT using 68Ga-DOTATATE (n = 9), 18F-FDG (n = 8), and positron emission tomography-magnetic resonance imaging (PET/MR) using 18F-FDG (n = 1). In this manuscript, 18F-FDG PET/CT refers to both 18F-FDG PET/CT and 18F-FDG PET/MR. The per-lesion, per-region, and per-patient detection rates were compared and calculated for each of the imaging modalities. A composite of all functional and anatomic imaging studies served as the imaging comparator. RESULTS: Eight out of nine patients were positive for PPGLs on the imaging studies that demonstrated 107 lesions in 22 anatomic regions on the imaging comparator. The per-lesion detection rates for 68Ga-DOTATATE PET/CT, 18F-FDG PET/CT, and CT/MR imaging were 93.5% (95%CI, 87.0% to 97.3%); 79.4% (95%CI, 70.5% to 86.6%); and 73.8% (95%CI, 64.5% to 81.9%), respectively. The per-lesion detection rate for 68Ga-DOTATATE PET/CT was significantly higher than that of 18F-FDG PET/CT (p = 0.001) or CT/MR imaging (p < 0.001). In all of the anatomic regions except abdomen, the per-lesion detection rates for 68Ga-DOTATATE PET/CT was found to be equal or superior to 18F-FDG PET/CT, and CT/MR imaging. The per-region detection rate was 100% (95%CI, 84.6% to 100%) for 68Ga-DOTATATE PET/CT and 90.9% (95%CI, 70.8% to 98.9%) for both 18F-FDG PET/CT and CT/MR imaging. The per-patient detection rates for 68Ga-DOTATATE PET/CT, 18FDG PET/CT, and CT/MR imaging were all 100% (95%CI, 63.1% to 100%). CONCLUSION: Our preliminary study demonstrates the superiority of 68Ga-DOTATATE PET/CT in localization of SDHx-related PPGLs in pediatric population compared to 18F-FDG PET/CT and CT/MR imaging with the exception of abdominal (excluding adrenal and liver) lesions, and suggests that it might be considered as a first-line imaging modality in pediatric patients with SDHx-related PPGLs.

Continued Tumor Reduction of Metastatic Pheochromocytoma/Paraganglioma Harboring Succinate Dehydrogenase Subunit B Mutations with Cyclical Chemotherapy.

Patients harboring germline mutations in the succinate dehydrogenase complex subunit B (SDHB) gene present with pheochromocytomas and paragangliomas (PPGL) that are more likely malignant and clinically aggressive. The combination chemotherapy cyclophosphamide, vincristine, and dacarbazine (CVD) was retrospectively evaluated in patients with SDHB-associated metastatic PPGL.Query Twelve metastatic PPGL patients harboring SDHB mutations/polymorphisms with undetectable SDHB immunostaining were treated with CVD. CVD therapy consisted of 750 mg/m2 cyclophosphamide with 1.4 mg/m2 vincristine on day 1 and 600 mg/m2 dacarbazine on days 1 and 2, every 21-28 days. Treatment outcome was determined by RECIST criteria as well as determination of response duration and progression-free and overall survivals. A median of 20.5 cycles (range 4-41) was administered. All patients had tumor reduction (12-100% by RECIST). Complete response was seen in two patients, while partial response was observed in 8. The median number of cycles to response was 5.5. Median duration of response was 478 days, with progression-free and overall survivals of 930 and 1190 days, respectively. Serial [18F]-fluorodeoxyglucose positron emission tomography and computed tomography imaging demonstrated continued incremental reduction in maximal standardized uptake values (SUVmax) values in 26/30 lesions. During treatment administration, the median SUV decreased from > 25 to < 6, indicating the efficacy of chemotherapy over a prolonged period of time. Prolonged therapy results in continued incremental tumor reduction, and is consistent with persistent drug sensitivity. CVD chemotherapy is recommended to be considered part of the initial management in patients with metastatic SDHB-related PPGL.

Transformative effects of Aboriginal health placements for medical, nursing, and allied health students: A systematic review.

The aim of the present systematic review was to investigate whether placements in Aboriginal health affect the self-perceived skill in working in Aboriginal health settings and career aspirations of health students, and in particular, aspects of the placement that had the greatest impact. The Embase, Cinahl, ProQuest, Scopus, Informit, Ovid MEDLINE, PsychINFO, and PubMed databases were searched in April/May 2016. Placements of at least 1 week duration in an Aboriginal health setting involving Australian students of medical, nursing, dentistry, or allied health disciplines, with outcomes relating to changes in students' knowledge, attitudes, and/or career aspirations, were included. The search retrieved 1351 papers. Fourteen studies were eligible for inclusion in this review. Narrative synthesis found that work placements in Aboriginal health increased understanding and awareness of Aboriginal culture, promoted deeper understanding of Aboriginal health determinant complexity, increased awareness of everyday racism toward Aboriginal Australians, and enhanced desire to work in Aboriginal health. There is a need for improved teaching and learning scholarship to understand whether placements improve students' skill working with Aboriginal people in health care or increase the likelihood of future employment in these settings.

Are patients with hormonally functional phaeochromocytoma and paraganglioma initially receiving a proper adrenoceptor blockade? A retrospective cohort study.

OBJECTIVE: Pharmacological treatment is mandatory in patients with hormonally functional phaeochromocytoma and paraganglioma (PHAEO/PGL). We evaluated if patients initially diagnosed with hormonally functional PHAEO/PGL by various medical subspecialties received proper adrenoceptor blockade, and analysed factors predicting the prescription of adequate treatment. METHODS: In a retrospective cohort study, we reviewed data from patients initially diagnosed with hormonally functional PHAEO/PGL outside the National Institutes of Health and Cedars-Sinai Medical Center, who were referred to these institutions between January 2001 and April 2015. Logistic regression was used to assess factors associated with proper adrenoceptor blockade. RESULTS: A total of 381 patients were included. Adequate pharmacological treatment was prescribed to 69·3%, of which 93·1% received α-adrenoceptor blockers. Regarding patients who were inappropriately treated, 53% did not receive any medication. Independent predictors of the prescription of a proper blockade were the diagnosis by endocrinologists [odds ratio (OR) 4·14; 95% confidence interval (CI), 2·51-6·85; P < 0·001], the presence of high blood pressure (OR 5·94; 95% CI, 3·11-11·33; P < 0·001) and the evidence of metastasis (OR 5·96; 95% CI, 1·93-18·46; P = 0·002). CONCLUSIONS: Although most patients received adequate pharmacological treatment, almost one-third were either not treated or received inappropriate medications. The diagnosis by endocrinologists, the presence of high blood pressure and the evidence of metastatic disease were identified as independent predictors of a proper blockade. These results highlight the need to educate physicians about the importance of starting adequate adrenoceptor blockade in all patients with hormonally functional PHAEO/PGL.

PET/CT comparing (68)Ga-DOTATATE and other radiopharmaceuticals and in comparison with CT/MRI for the localization of sporadic metastatic pheochromocytoma and paraganglioma.

PURPOSE: Pheochromocytomas/paragangliomas (PPGLs) and their metastases are tumors that predominantly express somatostatin receptor 2 (SSR2). (68)Ga-DOTA(0)-Tyr(3)-octreotate ((68)Ga-DOTATATE) is a PET radiopharmaceutical with both high and selective affinity for SSRs. The purpose of this study was to evaluate the utility of (68)Ga-DOTATATE in comparison with other specific and nonspecific radiopharmaceuticals recommended in the current guidelines for the localization of metastatic sporadic PPGL by PET/CT. METHODS: This prospective study included 22 patients (15 men, 7 women; aged 50.0 ± 13.9 years) with confirmed metastatic PPGL, a negative family history for PPGL, and negative genetic testing, who underwent (68)Ga-DOTATATE, (18)F-fluoro-2-deoxy-D-glucose ((18)F-FDG) PET/CT, and CT/MRI. Only 12 patients underwent an additional (18)F-fluorodihydroxyphenylalanine ((18)F-FDOPA) PET/CT scan and only 11 patients underwent an additional (18)F-fluorodopamine ((18)F-FDA) PET/CT scan. The rates of detection of metastatic lesions were compared among all the imaging studies. A composite of all functional and anatomical imaging studies served as the imaging comparator. RESULTS: (68)Ga-DOTATATE PET/CT showed a lesion-based detection rate of 97.6 % (95 % confidence interval, CI, 95.8 - 98.7 %). (18)F-FDG PET/CT, (18)F-FDOPA PET/CT, (18)F-FDA PET/CT, and CT/MRI showed detection rates of 49.2 % (CI 44.5 - 53.6 %; p < 0.01), 74.8 % (CI 69.0 - 79.9 %); p < 0.01), 77.7 % (CI 71.5 - 82.8 %; p < 0.01), and 81.6 % (CI 77.8 - 84.8 %; p < 0.01), respectively. CONCLUSION: The results of this study demonstrate the superiority of (68)Ga-DOTATATE PET/CT in the localization of sporadic metastatic PPGLs compared to all other functional and anatomical imaging modalities, and suggest modification of future guidelines towards this new imaging modality.

Applying to subspecialty fellowship: clarifying the confusion and conflicts!

Of graduating obstetrics and gynecology residents, 40% apply for fellowship training and this percentage is likely to increase. The fellowship interview process creates a substantial financial burden on candidates as well as significant challenges in scheduling the multiple interviews for residents, residency programs, and fellowship programs. Coverage with relatively short lead time is needed for some resident rotations, multiple residents may request time off during overlapping time periods, and applicants may not be able to interview based on conflicting interview dates or the inability to find coverage from other residents for their clinical responsibilities. To address these issues, we propose that each subspecialty fellowship within obstetrics and gynecology be allocated a specified and limited time period to schedule their interviews with minimal overlap between subspecialties. Furthermore, programs in close geographic areas should attempt to coordinate their interview dates. This will allow residents to plan their residency rotation schedules far in advance to minimize the impact on rotations that are less amenable to time away from their associated clinical duties, and decrease the numbers of residents needing time off for interviews during any one time period. In addition, a series of formal discussions should take place between subspecialties related to these issues as well as within subspecialties to facilitate coordination.

CHARACTERISTICS AND OUTCOMES OF METASTATIC SDHB AND SPORADIC PHEOCHROMOCYTOMA/PARAGANGLIOMA: AN NATIONAL INSTITUTES OF HEALTH STUDY.

OBJECTIVE: Overall about 10 to 20% of pheochromocytomas/paragangliomas (PHEOs/PGLs) are metastatic, with higher metastatic potential observed in succinate dehydrogenase subunit B/fumarate hydratase (SDHB/FH)-related tumors. Due to the improved availability of biochemical and genetic testing and the frequent use of anatomical/functional imaging, there is currently a higher detection rate of metastatic PHEO/PGL. METHODS: A retrospective analysis of 132 patients (27 children, 105 adults) with metastatic PHEO/PGL diagnosed and treated from 2000 to 2014 was conducted. RESULTS: Seventy-seven (58%) males and 55 (42%) females were included; 39 (30%) have died, with no sex preference. Seventy-three (55%) patients had SDHB mutations; 59 (45%) patients had apparently sporadic tumors (AST). SDHB patients had an average age at primary tumor diagnosis of 31 ± 16 years compared to 40 ± 15 years in AST patients (P<.001). The average metastatic interval (MI) decreased with increasing age in both SDHB and AST patients (P = .013 for both). Only 16% of all primary tumors were smaller than 4.5 cm. Eleven percent of patients had biochemically silent disease, more with SDHB. Of SDHB patients, 23% had metastatic tumors at first diagnosis, compared to 15% of AST patients. Five- and 10-year survival rates were significantly better for metastatic AST than SDHB patients (P = .01). Overall survival was significantly different between children and adults (P = .037); this was mostly attributed to the SDHB patients, in whom children had statistically significantly longer survival than adults (P = .006). The deceased patients all died due to the PHEO/PGL and mainly had noradrenergic phenotypes. CONCLUSION: In children, metastatic PHEOs/PGLs are mainly due to SDHB mutations; in adults they are equally distributed between in SDHB mutations and AST, with better 5- and 10-year survival rates for ASTs. In SDHB patients, children survive longer than adults. Primary metastatic tumors, most presenting as noradrenergic PGLs, are larger than 4.5 cm in >80% of patients. The frequency of metastatic tumors from primary AST increases with age, including a decreased MI compared to SDHB tumors. These results support several recommendations that are summarized in the Discussion.
