The benefits of contributing to the citizen science platform iNaturalist as an identifier.

As the number of observations submitted to the citizen science platform iNaturalist continues to grow, it is increasingly important that these observations can be identified to the finest taxonomic level, maximizing their value for biodiversity research. Here, we explore the benefits of acting as an identifier on iNaturalist.

"Out of the blue": A qualitative study exploring the experiences of women and next of kin receiving unexpected results from BRA-STRAP research gene panel testing.

In the genomic era, the availability of gene panel and whole genome/exome sequencing is rapidly increasing. Opportunities for providing former patients with new genetic information are also increasing over time and recontacting former patients with new information is likely to become more common. Breast cancer Refined Analysis of Sequence Tests-Risk And Penetrance (BRA-STRAP) is an Australian study of individuals who had previously undertaken BRCA1 and BRCA2 genetic testing, with no pathogenic variants detected. Using a waiver of consent, stored DNA samples were retested using a breast/ovarian cancer gene panel and clinically significant results returned to the patient (or next of kin, if deceased). This qualitative study aimed to explore patient experiences, opinions, and expectations of recontacting in the Australian hereditary cancer setting. Participants were familial cancer clinic patients (or next of kin) who were notified of a new pathogenic variant identified via BRA-STRAP. In-depth, semi-structured interviews were conducted approximately 6 weeks post-result. Interviews were transcribed verbatim and analyzed using an inductive thematic approach. Thirty participants (all female; average age = 57; range 36-84) were interviewed. Twenty-five were probands, and five were next of kin. Most women reported initial shock upon being recontacted with unexpected news, after having obtained a sense of closure related to their initial genetic testing experiences and cancer diagnosis. For most, this initial distress was short-lived, followed by a process of readjustment, meaning-making and adaptation that was facilitated by perceived clinical and personal utility of the information. Women were overall satisfied with the waiver of consent approach and recontacting process. Results are in line with previous studies suggesting that patients have positive attitudes about recontacting. Women in this study valued new genetic information gained from retesting and were satisfied with the BRA-STRAP recontact model. Practice implications to facilitate readjustment and promote psychosocial adaptation were identified.

The effect of botulinum toxin on ureteral inflammation.

PURPOSE: The impact of onabotulinum toxin type A (BoNT-A) on bladder afferent nerve pathways and chemosensory functions is an active area of investigation. There may be a role for BoNT-A in disorders of the ureter; however, no histologic studies have assessed the effects of BoNT-A on ureteral tissue. Our objective was to develop an animal model of ureteral inflammation and determine the impact of ureteral BoNT-A instillation on known mechanisms of inflammation. METHODS: The safety and feasibility of a novel animal model of ureteral inflammation was assessed. Through open cystotomy, the effect of ureteral BoNT-A instillation on inflammation was determined through H&E, masson's trichrome, Ki-67 stain, and prostaglandin E (PGE) synthase expression, a known marker of pain and inflammation in ureteral tissue. Urothelial microstructure was assessed using electron microscopy and standard histologic techniques. RESULTS: All experiments were carried to completion, and no systemic signs of botulinum toxicity were seen. BoNT-A exposure was associated with a decrease in PGE synthase expression in a dose-dependent fashion. BoNT-A exposure was not found to impact collagen deposition or cell proliferation. Disruption of tight junctions between urothelial cells was observed under conditions of inflammation. CONCLUSION: We describe the feasibility of a novel in vivo model of ureteral inflammation and report the first histologic study of the effects of BoNT-A on the ureter. Preliminary findings show that BoNT-A attenuates ureteral PGE synthase expression under conditions of inflammation. The application of BoNT-A may provide anti-inflammatory and analgesic effects in the context of ureteral disorders.

Gene Therapy for Glaucoma by Ciliary Body Aquaporin 1 Disruption Using CRISPR-Cas9.

Glaucoma is a common cause of blindness, yet current therapeutic options are imperfect. Clinical trials have invariably shown that reduction in intraocular pressure (IOP) regardless of disease subtype prevents visual loss. Reducing ciliary body aqueous humor production can lower IOP, and the adeno-associated virus ShH10 serotype was identified as able to transduce mouse ciliary body epithelium following intravitreal injection. Using ShH10 to deliver a single vector CRISPR-Cas9 system disrupting Aquaporin 1 resulted in reduced IOP in treated eyes (10.4 ± 2.4 mmHg) compared with control (13.2 ± 2.0 mmHg) or non-injected eyes (13.1 ± 2.8 mmHg; p < 0.001; n = 12). Editing in the aquaporin 1 gene could be detected in ciliary body, and no off-target increases in corneal or retinal thickness were identified. In experimental mouse models of corticosteroid and microbead-induced ocular hypertension, IOP could be reduced to prevent ganglion cell loss (32 ± 4 /mm2) compared with untreated eyes (25 ± 5/mm2; p < 0.01). ShH10 could transduce human ciliary body from post-mortem donor eyes in ex vivo culture with indel formation detectable in the Aquaporin 1 locus. Clinical translation of this approach to patients with glaucoma may permit long-term reduction of IOP following a single injection.

Slc6a3-dependent expression of a CAPS-associated Nlrp3 allele results in progressive behavioral abnormalities and neuroinflammation in aging mice.

BACKGROUND: An association between neuroinflammation and age-related neurologic disorders has been established but the molecular mechanisms and cell types involved have not been thoroughly characterized. Activity of the proinflammatory NLRP3 inflammasome is implicated in Alzheimer's and Parkinson's disease and our recent studies in patients suggest that dopaminergic neurons within the degenerating mesencephalon express NLRP3 throughout the progression of PD. Here, we directly test the impact of enhanced inflammasome activity in mesencephalic neurons by characterizing motor function, tissue integrity, and neuroinflammation in aging mice harboring hyperactivating mutations within the endogenous murine Nlrp3 locus, enabled only in cells expressing the dopaminergic neuron-specific Slc6a3 promoter. METHODS: We compared mice harboring inducible alleles encoding the cryopyrin-associated periodic syndrome activating mutations Nlrp3A350V and Nlrp3L351P inserted into the endogenous mouse Nlrp3 locus. Tissue specific expression was driven by breeding these animals with mice expressing Cre recombinase under the control of the dopaminergic neuron-specific Slc6a3 promoter. The experimental mice, designed to express hyperactive NLRP3 only when the endogenous mouse Nlrp3 promotor is active in dopaminergic neurons, were analyzed throughout 18 months of aging using longitudinal motor function assessments. Biochemical and histologic analyses of mesencephalic tissues were conducted in 1- and 18-month-old animals. RESULTS: We observed progressive and significant deficits in motor function in animals expressing Nlrp3L351P, compared with animals expressing Nlrp3WT and Nlrp3A350V. Age-dependent neuroinflammatory changes in the mesencephalon were noted in all animals. Analysis of GFAP-immunoreactive astrocytes in the substantia nigra revealed a significant increase in astrocyte number in animals expressing Nlrp3L351P compared with Nlrp3WT and Nlrp3A350V. Further analysis of Nlrp3L351P striatal tissues indicated genotype specific gliosis, elevated Il1b expression, and both morphologic and gene expression indicators of proinflammatory A1 astrocytes. CONCLUSIONS: Dopaminergic neurons have the potential to accumulate NLRP3 inflammasome activators with age, including reactive oxygen species, dopamine metabolites, and misfolded proteins. Results indicate the Nlrp3 locus is active in dopaminergic neurons in aging mice, and that the hyperactive Nlrp3L351P allele can drive neuroinflammatory changes in association with progressive behavioral deficits. Findings suggest neuronal NLRP3 inflammasome activity may contribute to neuroinflammation observed during normal aging and the progression of neurologic disorders.

Talking across generations: Family communication about BRCA1 and BRCA2 genetic cancer risk.

While family communication about a BRCA1 or BRCA2 (BRCA1/2) pathogenic variant can be a catalyst for the uptake of risk-reducing measures in young adults, disseminating information within families and across generations is complex. This study aimed to explore how young adults and their families communicate about a BRCA1/2 pathogenic variant, from a family systems perspective. In-depth family interviews and questionnaires (N = 67 individuals; 21 families) were completed at four metropolitan and regional genetic clinics in Australia. Data involved thematic analysis and interpretation based on family systems theory, including the use of standardized measures. Six key themes were identified and explored: (1) Responsibility to protect, (2) "It's a woman's problem," (3) Family culture influences communication, (4) Adversarial growth and connection, (5) Key events can be relational turning points, and (6) Health professionals can help. Family identities were solidified through the incorporation of a pathogenic variant in family scripts, while members of the family who held differing views to their families expressed less agreeableness and openness to disseminate information. The collective family's experience and perspective toward a pathogenic variant can influence a young adult's decision-making about genetic testing, risk-management, and family planning. The utilization of family therapy skills in routine practice would be helpful in facilitating communication and the inclusion of standardized measures is beneficial to identify individuals needing ongoing psychological support. Understanding relationship difficulties that arise from family members holding divergent views can offer insight into future research inquiry and areas of further training and clinical support.

Health professional and at-risk BRCA young adult perspectives about information needs: What does Gen Y need to know?

Young adults at risk of a hereditary condition require the provision of accurate information to make an informed decision about genetic testing and risk management options. At-risk young adults' (18- to 40-year olds) preferences for information and resources, and genetic-related health professionals' (GHPs) views on young adults' information needs, are largely unknown in the literature. This study aimed to clarify and compare the information needs of emerging (18- to 25-year olds) and early (26- to 40-year olds) adults. Resource preferences of young adults were also explored. Findings are drawn from two datasets: questionnaires and semi-structured interviews with at-risk young adults from BRCA1 or BRCA2 families (N = 32), and focus groups with GHPs (N = 73) working in Australian familial cancer clinics. Both datasets were analyzed using framework analysis. Emerging adults, particularly those who had not attended a clinic, wanted to know the rationale for genetic testing and basic genetic facts. Early adults were concerned about reproductive issues and cancer risk for future or current children. Information needs reported by young adults but not reported by GHPs include male cancer risk, finding reputable information, understanding test results (e.g., negative), and understanding risk terminology (e.g., lifetime cancer risk). Young adults' satisfaction with current information received was suboptimal, yet uptake of genetic-related resources was generally low. Getting information to this cohort remains a challenge for GHPs. Emerging adults showed a preference to obtain information through technologically-based formats (e.g., websites, social media), whereas early adults used a wider range of formats (e.g., websites, booklets). Awareness of and access to genetic information prior to genetic clinic attendance is needed. A review of the utility of current resources available for at-risk young adults would be helpful.

Family Communication, Risk Perception and Cancer Knowledge of Young Adults from BRCA1/2 Families: a Systematic Review.

Understanding challenges in familial communication of cancer risk has informed genetic service delivery. Parent-child interactions have received considerable attention, but few studies focus on young adulthood experiences within BRCA1/2 families. Young adults are approaching, or at a life stage where awareness of hereditary cancer risk is vital for informed choice of risk management options. This review assesses family communication, risk perception and cancer knowledge held by 18-40 year old individuals who have a parent with a BRCA1/2 gene mutation or carry the gene mutation themselves. Thirteen papers met the inclusion criteria. One utilized a 'mixed methods' methodology and the remaining used a qualitative approach. Findings were synthesized into themes and reported narratively. In general, parents are communicating openly about genetic risk with young adult offspring, but there is evidence that some young adults are withholding information from their parents about their own test results. Risk perception is influenced by a family history of cancer, childbearing plans and health providers' advice. Misconceptions about genetic risk appear to be common and gaps in hereditary cancer knowledge are evident. It is unclear whether incorrect knowledge was passed from parents to offspring. Health providers need to provide developmentally appropriate services for emerging adults (18-25 years old), with particular support in navigating through risk management options.

Responding to Acute Care Needs of Patients With Cancer: Recent Trends Across Continents.

Remarkable progress has been made over the past decade in cancer medicine. Personalized medicine, driven by biomarker predictive factors, novel biotherapy, novel imaging, and molecular targeted therapeutics, has improved outcomes. Cancer is becoming a chronic disease rather than a fatal disease for many patients. However, despite this progress, there is much work to do if patients are to receive continuous high-quality care in the appropriate place, at the appropriate time, and with the right specialized expert oversight. Unfortunately, the rapid expansion of therapeutic options has also generated an ever-increasing burden of emergency care and encroaches into end-of-life palliative care. Emergency presentation is a common consequence of cancer and of cancer treatment complications. It represents an important proportion of new presentations of previously undiagnosed malignancy. In the U.K. alone, 20%-25% of new cancer diagnoses are made following an initial presentation to the hospital emergency department, with a greater proportion in patients older than 70 years. This late presentation accounts for poor survival outcomes and is often associated with poor patient experience and poorly coordinated care. The recent development of acute oncology services in the U.K. aims to improve patient safety, quality of care, and the coordination of care for all patients with cancer who require emergency access to care, irrespective of the place of care and admission route. Furthermore, prompt management coordinated by expert teams and access to protocol-driven pathways have the potential to improve patient experience and drive efficiency when services are fully established. The challenge to leaders of acute oncology services is to develop bespoke models of care, appropriate to local services, but with an opportunity for acute oncology teams to engage cancer care strategies and influence cancer care and delivery in the future. This will aid the integration of highly specialized cancer treatment with high-quality care close to home and help avoid hospital admission.

The role of chest computed tomography (CT) as a surveillance tool in children with high-risk neuroblastoma.

BACKGROUND: Standardization of imaging obtained in children with neuroblastoma is not well established. This study examines chest CT in pediatric patients with high-risk neuroblastoma. PROCEDURE: Medical records and imaging from 88 patients with high-risk neuroblastoma, diagnosed at St. Jude Children's Research Hospital between January, 2002 and December, 2009, were reviewed. Surveillance imaging was conducted through 2013. Ten patients with thoracic disease at diagnosis were excluded. Event free survival (EFS) and overall survival (OS) were estimated. Size specific dose estimates for CT scans of the chest, abdomen, and pelvis were used to estimate absolute organ doses to 23 organs. Organ dosimetry was used to calculate cohort effective dose. RESULTS: The 5 year OS and EFS were 51.9% ± 6.5% and 42.6% ± 6.5%, respectively. Forty-six (58.9%) patients progressed/recurred and 41 (52.6%) died of disease. Eleven patients (14%) developed thoracic disease progression/recurrence identified by chest CT (1 paraspinal mass, 1 pulmonary nodules, and 9 nodal). MIBG (metaiodobenzylguanidine) scans identified thoracic disease in six patients. Five of the 11 had normal chest MIBG scans; three were symptomatic and two were asymptomatic with normal chest MIBG scans but avid bone disease. The estimated radiation dose savings from surveillance without CT chest imaging was 42%, 34% when accounting for modern CT acquisition (2011-2013). CONCLUSIONS: Neuroblastoma progression/recurrence in the chest is rare and often presents with symptoms or is identified using standard non-CT imaging modalities. For patients with non-thoracic high-risk neuroblastoma at diagnosis, omission of surveillance chest CT imaging can save 35-42% of the radiation burden without compromising disease detection.

Global trends in health research and development expenditures--the challenge of making reliable estimates for international comparison.

Better estimates of changes in the level and structure of national, regional, and global expenditures on health research and development (R&D) are needed as an important source of information for advancing countries' health research policies. However, such estimates are difficult to compile and comparison between countries needs careful calibration. We outline the steps that need to be taken to make reliable estimates of trends in countries' expenditures on health R&D, describe that an ideal approach would involve the use of international sets of deflators and exchange rates that are specific to health R&D activities, and explain which methods should be used given the current absence of such health R&D-specific deflators and exchange rates. Finally, we describe what should be the way forward in improving our ability to make reliable estimates of trends in countries' health R&D expenditures.

Combined osteochondral allograft and meniscal allograft transplantation: a survivorship analysis.

INTRODUCTION: The efficacy of meniscal allograft transplantation (MAT) and osteochondral allografting (OCA) as individual treatment modalities for select applications is well established. MAT and OCA are considered symbiotic procedures due to a complementary spectrum of indications and reciprocal contraindications. However, few outcomes of concomitant MAT and OCA have been reported. This study is a retrospective review of patients who received simultaneous MAT and OCA between 1983 and 2011. METHODS: Forty-eight (twenty-nine male: nineteen female) patients with a median age of 35.8 years (15-66) received combined MAT and OCA procedures between 1983 and 2011. Forty-three patients had received previous surgery with a median of 3 procedures (1-11 procedures). The underlying diagnosis was trauma (tibial plateau fracture) in 33 % with osteoarthritis predominating in 54.2 % of cases. Thirty-one patients received a lateral meniscus, 16 received a medial meniscus and one patient received bilateral MAT. The median number of OCAs was two per patient (1-5 grafts), with a median graft area of 15 cm(2) (0.7-41 cm(2)). There were 21 unipolar, 24 bipolar (tibiofemoral) and three multifocal lesions. Thirty-six MATs constituted a compound tibial plateau OCA with native meniscus attached. At follow-up, failure was defined as any procedure resulting in removal or revision of one or more of the grafts. Patients completed the modified Merle d'Aubigné and Postel (18-point) scale, Knee Society Function (KS-F) score, and subjective International Knee Documentation Committee (IKDC) scores. Patient satisfaction was also captured. RESULTS: Twenty-six of 48 patients (54.2 %) required reoperation, but only 11 patients (22.9 %) were noted to have failed (10 MAT and 11 OCA). The mean time to failure was 3.2 years (95 % CI 1.5-4.9 years) and 2.7 years (95 % CI 1.3-4.2 years) for MAT and OCA, respectively. The 5-year survivorship was 78 and 73 % for MAT and OCA respectively, and 69 and 68 % at 10 years. Six of the failures were in the OA cases and one was an OCD lesion where bipolar grafts were utilized. The OCD case underwent a revision OCA and remains intact. The others were converted to knee arthroplasty. One case failed due to early deep infection, ultimately requiring arthrodesis. Of those with grafts still intact, the mean clinical follow-up was 6.8 years (1.7-17.1 years). Statistically significant improvements in all outcome scores were noted between baseline and the latest follow-up. In total, 90 % of those responding would have the surgery again and 78 % were either extremely satisfied or satisfied with the outcome. CONCLUSION: The overall success rate of concomitant MAT and OCA was comparable with reported results for either procedure in isolation. A trend towards  a worse outcome was observed with bipolar tibiofemoral grafts in the setting of OA. Comparatively better results in less advanced, unipolar disease could suggest a benefit to early intervention that might merit a lower treatment threshold for combined MAT and OCA. LEVEL OF EVIDENCE: IV.

Mapping of available health research and development data: what's there, what's missing, and what role is there for a global observatory?

The need to align investments in health research and development (R&D) with public health demands is one of the most pressing global public health challenges. We aim to provide a comprehensive description of available data sources, propose a set of indicators for monitoring the global landscape of health R&D, and present a sample of country indicators on research inputs (investments), processes (clinical trials), and outputs (publications), based on data from international databases. Total global investments in health R&D (both public and private sector) in 2009 reached US$240 billion. Of the US$214 billion invested in high-income countries, 60% of health R&D investments came from the business sector, 30% from the public sector, and about 10% from other sources (including private non-profit organisations). Only about 1% of all health R&D investments were allocated to neglected diseases in 2010. Diseases of relevance to high-income countries were investigated in clinical trials seven-to-eight-times more often than were diseases whose burden lies mainly in low-income and middle-income countries. This report confirms that substantial gaps in the global landscape of health R&D remain, especially for and in low-income and middle-income countries. Too few investments are targeted towards the health needs of these countries. Better data are needed to improve priority setting and coordination for health R&D, ultimately to ensure that resources are allocated to diseases and regions where they are needed the most. The establishment of a global observatory on health R&D, which is being discussed at WHO, could address the absence of a comprehensive and sustainable mechanism for regular global monitoring of health R&D.

Political attitudes bias the mental representation of a presidential candidate's face.

Using a technique known as reverse-correlation image classification, we demonstrated that the face of Mitt Romney as represented in people's minds varies as a function of their attitudes toward Mitt Romney. Our findings provide evidence that attitudes bias how people see something as concrete and well learned as the face of a political candidate during an election. Practically, our findings imply that citizens may not merely interpret political information about a candidate to fit their opinion, but also may construct a political world in which they literally see candidates differently.

An Australian mainstream genetic testing program: Clinicians views about current and future practices.

PURPOSE: Germline genetic testing results can guide treatment decisions for oncology patients and are now offered to many cancer patients. Mainstream testing refers to genetic testing arranged by a non-genetics specialist. This repeated cross-sectional study aimed: (1) to capture clinician views on the existing mainstreaming genetic testing program for ovarian, breast, prostate, and endometrial cancer patients, and (2) to ascertain the interest of clinicians to consider changing practice to adopt mainstream testing. METHODS: Mainstreaming has occurred since 2015 for patients with ovarian and some breast cancer patients, expanding to include prostate cancer patients in 2019, and endometrial cancer patients in 2020. Two web-based surveys were administered within two health districts, covering seven hospitals in NSW. RESULTS: Fifty-four clinicians (70% response rate) participated. Clinicians who had arranged mainstream genetic testing (n = 30) were overall satisfied (76%), viewed the process as time-efficient and accessible for patients, and desired continuation of the program. Of those clinicians yet to engage in the program (n = 24), 88% expressed an interest in learning about mainstream testing. These clinicians identified time constraints, maintenance of current genetic knowledge, and completing the consenting and counseling process as barriers to mainstreaming. Future mainstreaming models are discussed. CONCLUSION: From the clinician's perspective, the mainstreaming program is considered a desirable pathway for germline testing of oncology patients. Access to ongoing education and resources is needed for the ongoing success of the program.

Dissecting cell death pathways in fed-batch bioreactors.

Chinese hamster ovary (CHO) cells are widely used for production of biologics including therapeutic monoclonal antibodies. Cell death in CHO cells is a significant factor in biopharmaceutical production, impacting both product yield and quality. Apoptosis has previously been described as the major form of cell death occurring in CHO cells in bioreactors. However, these studies were undertaken when less was known about non-apoptotic cell death pathways. Here, we report the occurrence of non-apoptotic cell death in an industrial antibody-producing CHO cell line during fed-batch culture. Under standard conditions, crucial markers of apoptosis were not observed despite a decrease in viability towards the end of the culture; only by increasing stress within the system did we observe caspase activation indicative of apoptosis. In contrast, markers of parthanatos and ferroptosis were observed during standard fed-batch culture, indicating that these non-apoptotic cell death pathways contribute to viability loss under these conditions. These findings pave the way for targeting non-conventional cell death pathways to improve viability and biologic production in CHO cells.

Young people in iNaturalist: a blended learning framework for biodiversity monitoring.

Participation in authentic research in the field and online through Community and Citizen Science (CCS) has shown to bring learning benefits to volunteers. In online CCS, available platforms present distinct features, ranging from scaffolding the process of data collection, to supporting data analysis and enabling volunteers to initiate their own studies. What is yet not well understood is how best to design CCS programmes that are educational, inclusive, and accessible by diverse volunteers, including young people and those with limited prior science experiences who are rather few in CCS. In this study, we interviewed 31 young people, aged 7-20 years old, who used iNaturalist, an online biodiversity monitoring platform, and identified how different forms of participation online and in the field facilitated (or inhibited) certain forms of learning, as defined by the Environmental Science Agency framework. Findings revealed that iNaturalist enabled participation of young people including those with limited science experiences and facilitated science learning such as the development of science competence and understanding. A blended learning framework for biodiversity monitoring in CCS is presented as a means to support the development of hybrid, educational, and inclusive CCS programmes for young people.

Proteomic Biomarkers for the Prediction of Transition to Psychosis in Individuals at Clinical High Risk: A Multi-cohort Model Development Study.

Psychosis risk prediction is one of the leading challenges in psychiatry. Previous investigations have suggested that plasma proteomic data may be useful in accurately predicting transition to psychosis in individuals at clinical high risk (CHR). We hypothesized that an a priori-specified proteomic prediction model would have strong predictive accuracy for psychosis risk and aimed to replicate longitudinal associations between plasma proteins and transition to psychosis. This study used plasma samples from participants in 3 CHR cohorts: the North American Prodrome Longitudinal Studies 2 and 3, and the NEURAPRO randomized control trial (total n = 754). Plasma proteomic data were quantified using mass spectrometry. The primary outcome was transition to psychosis over the study follow-up period. Logistic regression models were internally validated, and optimism-corrected performance metrics derived with a bootstrap procedure. In the overall sample of CHR participants (age: 18.5, SD: 3.9; 51.9% male), 20.4% (n = 154) developed psychosis within 4.4 years. The a priori-specified model showed poor risk-prediction accuracy for the development of psychosis (C-statistic: 0.51 [95% CI: 0.50, 0.59], calibration slope: 0.45). At a group level, Complement C8B, C4B, C5, and leucine-rich α-2 glycoprotein 1 (LRG1) were associated with transition to psychosis but did not surpass correction for multiple comparisons. This study did not confirm the findings from a previous proteomic prediction model of transition from CHR to psychosis. Certain complement proteins may be weakly associated with transition at a group level. Previous findings, derived from small samples, should be interpreted with caution.

Implementing Smoking Cessation Interventions for Tobacco Users Within Oncology Settings: A Systematic Review.

Importance: Patients with cancer who continue to smoke tobacco experience greater treatment-related complications, higher risk of secondary cancers, and greater mortality. Despite research to improve smoking cessation care within clinical oncology, implementation of proposed interventions within routine care remains challenging. Objective: To identify and recommend implementation strategies for smoking cessation interventions associated with improved screening, advice-giving, and referral for tobacco users recently diagnosed with cancer, as well as shifting smoking behaviors and attitudes in this patient population. Evidence Review: MEDLINE, CINAHL, Embase, and PsycINFO databases, as well as Google Scholar, were searched for articles published before September 7, 2020, using terms related to cancer, smoking cessation, and implementation science. Outcomes of interest were study characteristics, implementation strategies, and outcome measures (screening, advice, referral, abstinence rates, and attitudes). The Cochrane Risk of Bias Tool for randomized and nonrandomized studies was used to assess bias. The review was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline and Synthesis Without Meta-analysis (SWiM) guideline. Implementation strategies were categorized according to Expert Recommendations for Implementing Change (ERIC) study taxonomy. A systematic analysis was conducted focusing on studies with low or moderate risk of bias due to high heterogeneity in outcome measurement. Findings: In total, 6047 records were screened, yielding 43 articles (10 randomized clinical trials and 33 nonrandomized studies). Four strategies were associated with improved screening, advice-giving, and referral: (1) supporting clinicians, (2) training implementation stakeholders (including clinicians), (3) changing the infrastructure, and (4) developing stakeholder interrelationships. Conclusions and Relevance: In this systematic review, supporting clinicians by providing cessation care through a trained tobacco specialist was identified as important for achieving short-term abstinence and changing attitudes among patients with cancer. Combined with a theoretical framework and stakeholder involvement, these strategies provide the basis for successful implementation of cessation support; this systematic review serves as an illustration of the methodological application and synthesis of implementation studies and other medical conditions more generally.
