RESUMO
Neural action potentials (APs) are difficult to interpret as signal encoders and/or computational primitives. Their relationships with stimuli and behaviors are obscured by the staggering complexity of nervous systems themselves. We can reduce this complexity by observing that "simpler" neuron-less organisms also transduce stimuli into transient electrical pulses that affect their behaviors. Without a complicated nervous system, APs are often easier to understand as signal/response mechanisms. We review examples of nonneural stimulus transductions in domains of life largely neglected by theoretical neuroscience: bacteria, protozoans, plants, fungi, and neuron-less animals. We report properties of those electrical signals-for example, amplitudes, durations, ionic bases, refractory periods, and, particularly, their ecological purposes. We compare those properties with those of neurons to infer the tasks and selection pressures that neurons satisfy. Throughout the tree of life, nonneural stimulus transductions time behavioral responses to environmental changes. Nonneural organisms represent the presence or absence of a stimulus with the presence or absence of an electrical signal. Their transductions usually exhibit high sensitivity and specificity to a stimulus, but are often slow compared to neurons. Neurons appear to be sacrificing the specificity of their stimulus transductions for sensitivity and speed. We interpret cellular stimulus transductions as a cell's assertion that it detected something important at that moment in time. In particular, we consider neural APs as fast but noisy detection assertions. We infer that a principal goal of nervous systems is to detect extremely weak signals from noisy sensory spikes under enormous time pressure. We discuss neural computation proposals that address this goal by casting neurons as devices that implement online, analog, probabilistic computations with their membrane potentials. Those proposals imply a measurable relationship between afferent neural spiking statistics and efferent neural membrane electrophysiology.
RESUMO
We sought to determine the subspecialty interests of fourth-year medical students (MS4s) matched to Ob/Gyn and evaluate their attitudes towards residency tracking. Matched MS4s completed a survey regarding subspecialization, confidence in that choice, and desire for tracking. A total of 922 MS4s completed the survey. Of these, 474 (51.4%) desired subspecialty training, but were less confident in their choice compared with those desiring generalist careers (60.0/100 vs. 64.9/100, P =0.003). Those seeking subspecialty training were more likely to desire tracking (15.2% vs. 39.5%, P <0.001). In conclusion, 51% of MS4s desired subspecialty training over generalist careers. Almost 40% of these students are interested in tracking.

BACKGROUND: Metabolic syndrome (MetS) is characterised by the presence of at least three of the five following components: insulin resistance, obesity, chronic hypertension, elevated serum triglycerides, and decreased high-density lipoprotein cholesterol concentrations. It is estimated to affect 1 in 3 people around the globe and is reported to affect 46% of surgical patients. For people with MetS who undergo surgery, an emerging body of literature points to significantly poorer postoperative outcomes compared with nonaffected populations. The aim of this study is to review the current evidence on the risks of surgical complications in patients with MetS compared to those without MetS. METHODS: Systematic review and meta-analysis using PRISMA and AMSTAR reporting guidelines. RESULTS: The meta-analysis included 63 studies involving 1 919 347 patients with MetS and 11 248 114 patients without MetS. Compared to individuals without the condition, individuals with MetS were at an increased risk of mortality (OR 1.75 95% CI: 1.36-2.24; P <0.01); all surgical site infection types as well as dehiscence (OR 1.64 95% CI: 1.52-1.77; P <0.01); cardiovascular complications (OR 1.56 95% CI: 1.41-1.73; P <0.01) including myocardial infarction, stroke, cardiac arrest, cardiac arrythmias and deep vein thrombosis; increased length of hospital stay (MD 0.65 95% CI: 0.39-0.9; P <0.01); and hospital readmission (OR 1.55 95% CI: 1.41-1.71; P <0.01). CONCLUSION: MetS is associated with a significantly increased risk of surgical complications including mortality, surgical site infection, cardiovascular complications, increased length of stay, and hospital readmission. Despite these risks and the high prevalence of MetS in surgical populations there is a lack of evidence on interventions for reducing surgical complications in patients with MetS. The authors suggest prioritising interventions across the surgical continuum that include (1) preoperative screening for MetS; (2) surgical prehabilitation; (3) intraoperative monitoring and management; and (4) postoperative rehabilitation and follow-up.

OBJECTIVES: To develop a consensus on evidence-based principles and recommendations for perioperative hypothermia prevention in the Australian context. DESIGN: This study was informed by CAN-IMPLEMENT using the ADAPTE process: (1) formation of a multidisciplinary development team; (2) systematic search process identifying existing guidance for perioperative hypothermia prevention; (3) appraisal using the AGREE II Rigor of Development domain; (4) extraction of recommendations from guidelines meeting a quality threshold using the AGREE-REX tool; (5) review of draft principles and recommendations by multidisciplinary clinicians nationally and (6) subsequent round of discussion, drafting, reflection and revision by the original panel member team. SETTING: Australian perioperative departments. PARTICIPANTS: Registered nurses, anaesthetists, surgeons and anaesthetic allied health practitioners. RESULTS: A total of 23 papers (12 guidelines, 6 evidence summaries, 3 standards, 1 best practice sheet and 1 evidence-based bundle) formed the evidence base. After evidence synthesis and development of draft recommendations, 219 perioperative clinicians provided feedback. Following refinement, three simple principles for perioperative hypothermia prevention were developed with supporting practice recommendations: (1) actively monitor core temperature for all patients at all times; (2) warm actively to keep body temperature above 36°C and patients comfortable and (3) minimise exposure to cold at all stages of perioperative care. CONCLUSION: This consensus process has generated principles and practice recommendations for hypothermia prevention that are ready for implementation with local adaptation. Further evaluation will be undertaken in a large-scale implementation trial across Australian hospitals.

OBJECTIVES: Qualitative studies nested within clinical trials can provide insight into the treatment experience, how this evolves over time and where improved supportive care is required. The purpose of this qualitative study is to describe the lived experiences of men with advanced prostate cancer participating in the TheraP trial; a randomised trial of 177Lu-PSMA-617 compared with cabazitaxel chemotherapy. METHODS: Fifteen men with advanced prostate cancer were recruited from the TheraP clinical trial with interviews conducted at three timepoints during the trial. An interpretative phenomenological approach was used, and interviews analysed using thematic analysis. This research paper reports the results from the mid-point, conclusion and follow up interviews, focusing specifically on participants' experiences of trial participation. RESULTS: Three themes were identified representing the lived experiences of men with advanced prostate cancer participating in the TheraP trial: (1) facing limited options; (2) anticipating outcomes and (3) coping with health changes. CONCLUSIONS: Men who enrol in clinical trial of anti-neoplastic treatments for prostate cancer need targeted psychological and supportive care that includes attention to unique aspects of the experience of having prostate cancer and being in a clinical trial. As part of their trial experience, men with advanced prostate cancer need to be regularly assessed for survivorship needs, fully informed, supported and referred to services for regular care and support across the trajectory of their disease. TRIAL REGISTRATION: NCT03392428. Registered on 8 January 2018 (ANZUP1603).

Earth orbit is a limited natural resource that hosts a vast range of vital space-based systems that support the international community's national, commercial and defence interests. This resource is rapidly becoming depleted with over-crowding in high demand orbital slots and a growing presence of space debris. We propose the Fast Iterative Extraction of Salient targets for Tracking Asynchronously (FIESTA) algorithm as a robust, real-time and reactive approach to optical Space Situational Awareness (SSA) using Event-Based Cameras (EBCs) to detect, localize, and track Resident Space Objects (RSOs) accurately and timely. We address the challenges of the asynchronous nature and high temporal resolution output of the EBC accurately, unsupervised and with few tune-able parameters using concepts established in the neuromorphic and conventional tracking literature. We show this algorithm is capable of highly accurate in-frame RSO velocity estimation and average sub-pixel localization in a simulated test environment to distinguish the capabilities of the EBC and optical setup from the proposed tracking system. This work is a fundamental step toward accurate end-to-end real-time optical event-based SSA, and developing the foundation for robust closed-form tracking evaluated using standardized tracking metrics.
RESUMO
OBJECTIVES: Despite the widely publicised health benefits of participation in bowel cancer screening, only 43.5% of recipients participate in the Australian National Bowel Cancer Screening Program (NBCSP). Through consultation with kit recipients, this study aimed to identify features of home bowel screening kits that could be modified to increase their use. METHOD: Participants (n = 25) were presented with nine different bowel cancer screening kits and asked to identify features of each kit that might prevent or promote their use. Responses were coded using content analysis, and a narrative synthesis is presented summarising preferences relating to each element of the kit. RESULTS: Six modifiable elements were identified: collection tool, collection sheet, specimen container, instruction, packaging and processes. Participant preferences were for collection devices that limited the users' proximity to faecal matter, smaller packaging, simpler processes and step-by-step pictorial instructions. Responses regarding aesthetics, the amount of information included and receiving immediate results were mixed. CONCLUSIONS: Findings provide several consumer-driven recommendations, which are to be tested in future research aimed at improving the acceptability and usability of kits distributed in population bowel cancer screening programs.

Neuromorphic engineering aims to build (autonomous) systems by mimicking biological systems. It is motivated by the observation that biological organisms-from algae to primates-excel in sensing their environment, reacting promptly to their perils and opportunities. Furthermore, they do so more resiliently than our most advanced machines, at a fraction of the power consumption. It follows that the performance of neuromorphic systems should be evaluated in terms of real-time operation, power consumption, and resiliency to real-world perturbations and noise using task-relevant evaluation metrics. Yet, following in the footsteps of conventional machine learning, most neuromorphic benchmarks rely on recorded datasets that foster sensing accuracy as the primary measure for performance. Sensing accuracy is but an arbitrary proxy for the actual system's goal-taking a good decision in a timely manner. Moreover, static datasets hinder our ability to study and compare closed-loop sensing and control strategies that are central to survival for biological organisms. This article makes the case for a renewed focus on closed-loop benchmarks involving real-world tasks. Such benchmarks will be crucial in developing and progressing neuromorphic Intelligence. The shift towards dynamic real-world benchmarking tasks should usher in richer, more resilient, and robust artificially intelligent systems in the future.
RESUMO
BACKGROUND: Partners of men living with prostate cancer (PCa) can experience a variety of unmet needs that are largely unaddressed by health care professionals. There is limited evidence to suggest which approach may be most effective in supporting partners' unmet needs and further research is required to determine how to provide support to caregivers and how technology solutions can be designed. OBJECTIVE: This study aims to explore the experience of partners of men living with PCa and their perceptions of the potential role of information technology in supporting their needs. METHODS: A qualitative descriptive methodology using focus groups and phone interviews was used. Purposive sampling was used to recruit people attending a national conference supported by a national PCa organization. Interview guides were adapted from an existing evidence-based smartphone app for caregivers of people with colorectal cancer. Sessions were audio recorded and transcribed verbatim. A coding framework was developed, and transcripts were coded line by line into the framework. Codes within the framework were grouped into descriptive categories that were then developed into analytical themes. RESULTS: A total of 17 female partners participated in the study, with an average age of 64 (SD 8.5) years. The following two main themes emerged: In the first theme, that is, How technology can be shaped to support female partners of prostate cancer survivors, the content and design of the smartphone app was discussed in addressing female partners' needs. The following four subthemes were developed: getting support from social networks and resources, the lack of relevant information, demystifying future care expectations during and following a PCa diagnosis, and delivering the smartphone app-to whom and from whom. In the second theme, that is, The benefits and barriers of technology, the suitability of smartphone apps as a supportive modality for female partners was described. This included three subthemes: the smartphone app as an appropriate modality for supporting female partners, the future anticipated benefits of using the smartphone app, and concerns for storing and accessing information on the internet. CONCLUSIONS: A smartphone app may be a suitable modality for providing information and peer support to female partners of men living with PCa. There is a need to provide peer support for female partners in future interventions to ensure that female partners' intimacy and daily practical needs are met.
RESUMO
Theory-based, user-informed interventions are needed to increase the low participation rates of population-based faecal occult blood test (FOBT) bowel cancer screening. This study investigated the theoretical fit of the health action process approach (HAPA) for home FOBT screening and measured screening invitees' attitudes towards different intervention strategies. A cross-sectional sample (n = 377), aged 50-74 years, participated in this study. Two scales were created for this study. The process approach to mail-out screening (PAMS) scale measured HAPA constructs, and the user ratings of mail-out screening interventions (UR-MSI) scale measured attitudes towards different intervention strategies. Structural equation modelling was used to assess the fit of PAMS scale responses to the HAPA model, and descriptive statistics were calculated for UR-MSI responses. PAMS results showed acceptable model fit, CFI = .968, RMSEA = .050 and explained 49.9% of the variation in FOBT screening participation. Positive ratings of interventions ranged from 20.47%, an intervention prompting planning to complete the FOBT kit, to 72.25%, an intervention promoting the positive health outcome associated with FOBT screening. Intervention strategies should be combined such that they target all factors specified within the HAPA model. User-informed intervention design should be used to effectively facilitate FOBT uptake in the community.

We report optically detected magnetic resonance (ODMR) measurements of an ensemble of spin-1 negatively charged boron vacancies in hexagonal boron nitride. The photoluminescence decay rates are spin-dependent, with intersystem crossing rates of 1.02 ns-1 and 2.03 ns-1 for the mS = 0 and mS = ±1 states, respectively. Time gating the photoluminescence enhances the ODMR contrast by discriminating between different decay rates. This is particularly effective for detecting the spin of the optically excited state, where a zero-field splitting of |DES| = 2.09 GHz is measured. The magnetic field dependence of the photoluminescence exhibits dips corresponding to the ground (GSLAC) and excited-state (ESLAC) anticrossings and additional anticrossings due to coupling with nearby spin-1/2 parasitic impurities. Comparison to a model suggests that the anticrossings are mediated by the interaction with nuclear spins and allows an estimate of the ratio of the singlet to triplet spin-dependent relaxation rates of κ0/κ1 = 0.34.
RESUMO
The purpose of this systematic review and synthesis of studies reporting qualitative data was to understand the gendered experiences of female partners of prostate cancer survivors to inform psychosocial support for women. We searched Medline, PsycINFO, EMBASE, AMED, CINAHL, Cochrane Database of Systematic Reviews, and Sociological Abstracts for articles on 15 and 16 April 2019, and again on 30 November 2020. English language articles published in peer-reviewed journals were included if they reported solely on findings describing the perspectives of the female partners. Extracted data were analysed using line-by-line coding, organisation of codes into descriptive themes, and development of analytical themes. A theoretical framework was then selected to organise the relationships between issues that were found to be central to the experiences of female partners. Of 4839 articles screened, 14 met inclusion criteria, reporting 13 studies with a total sample of 359 female partners. Ussher and Sandoval's theory to describe the gendered positionings of cancer caregivers accommodated the thematic findings. The overarching theme reflected the substantive psychosocial impact of prostate cancer on female partners. Women's experiences were influenced by self-positioning (as part of a couple; provider of support to their male partner; resilient; and guided by faith and spirituality), being positioned by their partners' response (manager of male partner's psychological distress or strengthened by male partner's positive response) and by their broader contexts (family members and social networks; clinicians and the health system; and cultural values and customs). Findings highlight the need to avoid reductionist approaches to gender. Greater consideration of 'contextualised femininities', or conceptualising the influence of gender roles, relations, and identities within the wider life course contexts of female partners is required in the design and delivery of psychosocial support services.

OBJECTIVES: Nested qualitative studies within clinical trials provide the opportunity to better understand participant experiences of participation and identify areas where improved support is required. The purpose of this qualitative study is to describe the lived experiences of men with advanced prostate cancer participating in the TheraP trial; a randomised trial of 177Lu-PSMA-617 compared with cabazitaxel chemotherapy. METHODS: Fifteen men with advanced prostate cancer were recruited from the TheraP clinical trial and interviewed at three time points during the trial. Interviews were inductively analysed using thematic analysis. This research paper reports the results from the baseline interview at commencement of the trial, focusing specifically on participants' enrolment experiences. RESULTS: Four themes were identified representing the lived experiences of men with advanced prostate cancer deciding to participate in the TheraP trial: (1) hoping to survive; (2) needing to feel informed; (3) choosing to participate and (4) being randomised. The process of deciding to enrol in a clinical trial is filled with indecision, emotional difficulties and focused on a desire to live. CONCLUSIONS: For men with advanced prostate cancer, the experience of deciding to enrol in a clinical trial is principally driven by a desire to survive but interlinked with the need to make an informed decision as participants in this study expressed a preference for allocation to the experimental arm. Men seeking to enrol in clinical trials of new prostate cancer treatments would benefit from improved informational and decision support. TRIAL REGISTRATION NUMBER: NCT03392428, ANZUP1603.
RESUMO
AIMS AND OBJECTIVES: To report patient and family intensive care experiences using the Measuring the Intensive Care Experience (MICE) tool across two intensive care units (ICU). BACKGROUND: The patient and family experience of care is an important indicator for quality improvement of ICUs, yet few studies evaluate both patient and family experiences in relation to overall care quality as well as specifically measuring quality of medical care, nursing care and organisational care as well as overall experience of the quality of intensive care. DESIGN: A cross-sectional survey. METHODS: A 23 item survey was administered to ICU patients and their family members across two ICUs, a regional 189-bed hospital and a metropolitan 227-bed hospital in Queensland, Australia. The response rate was 272 of 394 ICU patients (36.4%). STROBE guidelines were used in reporting this study. RESULTS: Findings indicate a highly positive overall experience of ICU care among patients and families. However, patients reported areas of unmet needs following their stay in ICU broadly related to (1) symptom management, education and information support, and (2) improving the incorporation of patient and family care ICU-related shared decision-making. CONCLUSIONS: Supportive interventions are needed that target improve symptom management and inform and education ICU patients. RELEVANCE TO CLINICAL PRACTICE: The MICE survey facilitated the identification of a range of areas requiring quality improvement. Improving the integration of patients and families into shared decision-making and support is a key aspect for quality improvement.

We demonstrate the use of Stimulated Emission Depletion (STED) spectroscopy to map the electron-optical-phonon sideband of the ground state of the radiative transition of color centers in hexagonal boron nitride emitting at 2.0-2.2 eV, with in-plane linear polarization. The measurements are compared to photoluminescence of excitation (PLE) spectra that maps the electron-optical-phonon sideband of the excited state. The main qualitative difference is a red-shift in the longitudinal optical phonon peak associated with E 1u symmetry at the zone center. We compare our results to theoretical work on different defect species in hBN and find they are consistent with a carbon-based defect.
RESUMO
OBJECTIVE: To develop and test a psychometric instrument for measuring common barriers to completing and returning home bowel cancer screening kits. METHODS: One hundred and ten items were reviewed by an expert panel (n = 15) and presented in an online cross-sectional survey with 427 Australian adults. Exploratory factor analysis was used to identify an optimal factor solution of latent barrier types and aggregated factor scores were examined and compared between demographic groups. RESULTS: Common barriers included having already been screened (32.3%), forgetting about the kit (24.4%), and a lack of planning (21.8%). Barriers reflecting hygiene concerns were also endorsed by over 15% of the sample. Four clear barrier types were evident reflecting disgust, avoidance, lack of autonomy, and physical difficulties. CONCLUSIONS: Findings support calls to apply multi-faceted interventions strategies that address a broad range of barrier types, particularly that which encourage planning, and prompt and facilitate easy stool collection.

OBJECTIVES: To measure rates of detection via screening, perceived self-imposed delays in seeking medical attention, and support seeking in a sample of regional and remote people with a cancer diagnosis and to test whether an association exists between these behaviours and minimising problems and resignation, a need for self-control and reliance and fatalism. Correlations and binary logistic regressions were conducted to test the associations between demographic characteristics, attitudes and behaviours. RESULTS: Females were more likely to have had their cancer detected via screening (OR = 10.02, CI = 3.49-28.78). Younger participants (r = -0.103, p = 0.009) were slightly more likely to seek at least one form of support and online support was sought more often by younger patients (r = -0.269, p < 0.001), females (r = 0.152, p < 0.001), those from higher socio-economic (SES) areas (r = 0.100, p = 0.012), and those with higher education levels (r = 0.247, p < 0.001). Younger (r = -0.161, p < 0.001), and female (r = 0.82, p = 0.013), participants were also slightly more likely to seek support specifically through cancer support groups. No significant relationships between minimising problems and resignation, needs for control and self-reliance or fatalism and detection via screening, support seeking, or perceived self-imposed delays to seeking medical attention were apparent, with the exception that those with higher fatalism (predetermined health) were slightly less likely to report seeking support or information online (OR = 0.79, CI = 0.65-0.95) and slightly more likely to report using Cancer Council's support services (OR = 1.24, CI = 1.02-1.52). CONCLUSIONS: Strategies to improve the accessibility and appropriateness of support available for regional and remote cancer patients should consider interventions that remove barriers to access associated with age, gender, and education as opposed to those which address the attitudinal traits measured here.

OBJECTIVE: To examine the health services experience of patients with cancer from regional and remote Australia using the Australian National Cancer Control Indicators (NCCI) guidelines as an assessment framework. DESIGN: Cross-sectional. SETTING: Queensland non-for-profit cancer accommodation lodges. PARTICIPANTS: Participants were patients with cancer who travelled for treatment from rural and remote Queensland to major urban centres (n=518; age mean=64.6, SD=11.18). OUTCOME MEASURES: Assessments included NCCI patient indicators, quality of life (QoL), psychological distress and unmet supportive care needs. RESULTS: The frequency at which NCCI indicators were met ranged from 37.5% for receiving an assessment and care plan to 97.3% for understanding explanations about diagnosis. Geographical considerations did not impact patient experience, whereas middle school educated participants were more likely than those with senior-level education or higher to receive an assessment and care plan (OR=1.90, 95% CI 1.23 to 2.91) and to report having their views on treatment taken into account (OR=2.22, 95% CI 1.49 to 3.33). Patients with breast or prostate cancer reported better communication and patient involvement and information and services provision (r=p<0.001) compared with those with skin and head and neck cancer. When compared with information and service provision, communication and patient involvement showed stronger positive associations with QoL (z=2.03, p=0.042), psychosocial (z=2.05, p=0.040) and patient care (z=2.00, p=0.046) outcomes. CONCLUSION: The patient care experience varies across the NCCI indicators by sociodemographic and clinical factors that likely reflect healthcare system biases. Perceptions about communication and involvement appear most critical for optimal outcomes and should be a priority action area for cancer control.

OBJECTIVE: To develop contemporary and inclusive prostate cancer survivorship guidelines for the Australian setting. PARTICIPANTS AND METHODS: A four-round iterative policy Delphi was used, with a 47-member expert panel that included leaders from key Australian and New Zealand clinical and community groups and consumers from diverse backgrounds, including LGBTQIA people and those from regional, rural and urban settings. The first three rounds were undertaken using an online survey (94-96% response) followed by a fourth final face-to-face panel meeting. Descriptors for men's current prostate cancer survivorship experience were generated, along with survivorship elements that were assessed for importance and feasibility. From these, survivorship domains were generated for consideration. RESULTS: Six key descriptors for men's current prostate cancer survivorship experience that emerged were: dealing with side effects; challenging; medically focused; uncoordinated; unmet needs; and anxious. In all, 26 survivorship elements were identified within six domains: health promotion and advocacy; shared management; vigilance; personal agency; care coordination; and evidence-based survivorship interventions. Consensus was high for all domains as being essential. All elements were rated high on importance but consensus was mixed for feasibility. Seven priorities were derived for immediate action. CONCLUSION: The policy Delphi allowed a uniquely inclusive expert clinical and community group to develop prostate cancer survivorship domains that extend beyond traditional healthcare parameters. These domains provide guidance for policymakers, clinicians, community and consumers on what is essential for step change in prostate cancer survivorship outcomes.

BACKGROUND: Clinical trials are essential for the advancement of cancer treatments; however, participation by patients is suboptimal. Currently, there is a lack of synthesized qualitative review evidence on the patient experience of trial entry from which to further develop decision support. The aim of this review is to synthesise literature reporting experiences of participants when deciding to enrol in a cancer clinical trial in order to inform practice. METHODS: A systematic review and meta-synthesis of qualitative studies were conducted to describe the experiences of adult cancer patients who decided to enrol in a clinical trial of an anti-cancer treatment. RESULTS: Forty studies met eligibility criteria for inclusion. Three themes were identified representing the overarching domains of experience when deciding to enrol in a cancer trial: 1) need for trial information; (2) trepidation towards participation; and (3) justifying the decision. The process of deciding to enrol in a clinical trial is one marked by uncertainty, emotional distress and driven by the search for a cure. CONCLUSION: Findings from this review show that decision support modelled by shared decision-making and the quality of a shared decision needs to be accompanied by tailored or personalised psychosocial and supportive care. Although the decision process bears similarities to theoretical processes outlined in decision-making frameworks, there are a lack of supportive interventions for cancer patients that are adapted to the clinical trial context. Theory-based interventions are urgently required to support the specific needs of patients deciding whether to participate in cancer trials.
