Gender inequalities across ethnicities in primary care cancer referrals: scoping review protocol.

BACKGROUND: Early cancer diagnosis is associated with improved mortality and morbidity; however, studies indicate that women and individuals from ethnic minorities experience longer times to diagnosis and worse prognosis compared to their counterparts for various cancers. In countries with a gatekeeper healthcare system, such as UK, most suspected cancer referrals are initiated in primary care. AIM: To understand the extent of evidence available on the relationship between primary care cancer referral pathways and cancer outcomes in relation to gender across different ethnic groups. This will identify research gaps and enable development of strategies to ease potential inequalities in cancer diagnosis. DESIGN & SETTING: A scoping review based on the Joanna Briggs Institute methodology. PRISMA-ScR will be used. METHOD: Electronic databases and private collections of the team members will be searched for studies. Two independent reviewers will carry out the study selection and data extraction. Based on participants, concept and context framework, this review will consider studies after year 2000 that explored the relationship between gender, across various ethnic groups, and cancer outcomes following primary care cancer referral in countries with gatekeeper healthcare systems (UK, New Zealand, Sweden, Australia, Canada, Denmark, Ireland and Norway). Results will be presented as a narrative analysis. CONCLUSION: The results are expected to provide an overview of the discrepancies in primary care cancer referrals based on gender across ethnic groups, which will be crucial to define an appropriate range of strategies to ease any inequalities in primary healthcare cancer diagnosis.

Patterns of neurological adverse events among a retrospective cohort of patients receiving immune checkpoint inhibitors.

Aim: Neurological adverse events (NAEs) are infrequent immune checkpoint inhibitor (ICI) outcomes poorly characterized in extant research, complicating their clinical management. Methods: This study characterized the frequency, severity, patterning and timing of NAEs using a large retrospective registry, including all patients who received at least one dose of an ICI from 2/1/2011-4/7/2022 within our health network. Results: Among 3137 patients, there were 54 NAEs (1.72% any grade; 0.8% grade 3-4). Most NAEs were peripheral (57.4%) versus central (42.6%). Melanoma and renal cell carcinoma were significantly associated with NAEs. Conclusion: The incidence of NAEs was rare though higher than many prior case estimates; the timing was consistent with other AEs. NAEs frequently occurred in tumor types known to favor brain metastases.

Immune checkpoint inhibitors are new drugs for cancer. They boost your body's defenses to fight cancer cells. These drugs can be used alone or with other cancer treatments. Most people are okay with these medicines, but some might have problems in different parts of the body. This can be tricky to figure out. Rarely, there can be issues in the brain or nerves. These side effects are rare, happening in about 2 in every 100 people who use the drugs. They are more common in certain cancers like melanoma and kidney cancer. As doctors learn more about these side effects, they can better predict, treat, and prevent them.

Type 3 secretion system induced leukotriene B4 synthesis by leukocytes is actively inhibited by Yersinia pestis to evade early immune recognition.

Subverting the host immune response to inhibit inflammation is a key virulence strategy of Yersinia pestis. The inflammatory cascade is tightly controlled via the sequential action of lipid and protein mediators of inflammation. Because delayed inflammation is essential for Y. pestis to cause lethal infection, defining the Y. pestis mechanisms to manipulate the inflammatory cascade is necessary to understand this pathogen's virulence. While previous studies have established that Y. pestis actively inhibits the expression of host proteins that mediate inflammation, there is currently a gap in our understanding of the inflammatory lipid mediator response during plague. Here we used the murine model to define the kinetics of the synthesis of leukotriene B4 (LTB4), a pro-inflammatory lipid chemoattractant and immune cell activator, within the lungs during pneumonic plague. Furthermore, we demonstrated that exogenous administration of LTB4 prior to infection limited bacterial proliferation, suggesting that the absence of LTB4 synthesis during plague contributes to Y. pestis immune evasion. Using primary leukocytes from mice and humans further revealed that Y. pestis actively inhibits the synthesis of LTB4. Finally, using Y. pestis mutants in the Ysc type 3 secretion system (T3SS) and Yersinia outer protein (Yop) effectors, we demonstrate that leukocytes recognize the T3SS to initiate the rapid synthesis of LTB4. However, several Yop effectors secreted through the T3SS effectively inhibit this host response. Together, these data demonstrate that Y. pestis actively inhibits the synthesis of the inflammatory lipid LTB4 contributing to the delay in the inflammatory cascade required for rapid recruitment of leukocytes to sites of infection.

Cardiovascular health assessment in routine cancer follow-up in community settings: survivor risk awareness and perspectives.

BACKGROUND: Guidelines recommend cardiovascular risk assessment and counseling for cancer survivors. For effective implementation, it is critical to understand survivor cardiovascular health (CVH) profiles and perspectives in community settings. We aimed to (1) Assess survivor CVH profiles, (2) compare self-reported and EHR-based categorization of CVH factors, and (3) describe perceptions regarding addressing CVH during oncology encounters. METHODS: This cross-sectional analysis utilized data from an ongoing NCI Community Oncology Research Program trial of an EHR heart health tool for cancer survivors (WF-1804CD). Survivors presenting for routine care after potentially curative treatment recruited from 8 oncology practices completed a pre-visit survey, including American Heart Association Simple 7 CVH factors (classified as ideal, intermediate, or poor). Medical record abstraction ascertained CVD risk factors and cancer characteristics. Likert-type questions assessed desired discussion during oncology care. RESULTS: Of 502 enrolled survivors (95.6% female; mean time since diagnosis = 4.2 years), most had breast cancer (79.7%). Many survivors had common cardiovascular comorbidities, including high cholesterol (48.3%), hypertension or high BP (47.8%) obesity (33.1%), and diabetes (20.5%); 30.5% of survivors received high cardiotoxicity potential cancer treatment. Less than half had ideal/non-missing levels for physical activity (48.0%), BMI (18.9%), cholesterol (17.9%), blood pressure (14.1%), healthy diet (11.0%), and glucose/ HbA1c (6.0%). While > 50% of survivors had concordant EHR-self-report categorization for smoking, BMI, and blood pressure; cholesterol, glucose, and A1C were unknown by survivors and/or missing in the EHR for most. Most survivors agreed oncology providers should talk about heart health (78.9%). CONCLUSIONS: Tools to promote CVH discussion can fill gaps in CVH knowledge and are likely to be well-received by survivors in community settings.

Microneedle array delivery of Yersinia pestis recapitulates bubonic plague.

Fleas transmit Yersinia pestis directly within the dermis of mammals to cause bubonic plague. Syringe-mediated inoculation is widely used to recapitulate bubonic plague and study Y. pestis pathogenesis. However, intradermal needle inoculation is tedious, error prone, and poses a significant safety risk for laboratorians. Microneedle arrays (MNAs) are micron-scale polymeric structures that deliver materials to the dermis, while minimizing the risk of needle sticks. We demonstrated that MNA inoculation is a viable strategy to recapitulate bubonic plague and study bacterial virulence by defining the parameters needed to establish a lethal infection in the mouse model and characterizing the course of infection using live-animal optical imaging. Using MNAs, we also demonstrated that Y. pestis must overcome calprotectin-mediated zinc restriction within the dermis and dermal delivery of an attenuated mutant has vaccine potential. Together, these data demonstrate that MNAs are a safe alternative to study Y. pestis pathogenesis in the laboratory.

The role of funded partnerships in working towards decreasing COVID-19 vaccination disparities, United States, March 2021-December 2022.

During the COVID-19 vaccination rollout from March 2021- December 2022, the Centers for Disease Control and Prevention funded 110 primary and 1051 subrecipient partners at the national, state, local, and community-based level to improve COVID-19 vaccination access, confidence, demand, delivery, and equity in the United States. The partners implemented evidence-based strategies among racial and ethnic minority populations, rural populations, older adults, people with disabilities, people with chronic illness, people experiencing homelessness, and other groups disproportionately impacted by COVID-19. CDC also expanded existing partnerships with healthcare professional societies and other core public health partners, as well as developed innovative partnerships with organizations new to vaccination, including museums and libraries. Partners brought COVID-19 vaccine education into farm fields, local fairs, churches, community centers, barber and beauty shops, and, when possible, partnered with local healthcare providers to administer COVID-19 vaccines. Inclusive, hyper-localized outreach through partnerships with community-based organizations, faith-based organizations, vaccination providers, and local health departments was critical to increasing COVID-19 vaccine access and building a broad network of trusted messengers that promoted vaccine confidence. Data from monthly and quarterly REDCap reports and monthly partner calls showed that through these partnerships, more than 295,000 community-level spokespersons were trained as trusted messengers and more than 2.1 million COVID-19 vaccinations were administered at new or existing vaccination sites. More than 535,035 healthcare personnel were reached through outreach strategies. Quality improvement interventions were implemented in healthcare systems, long-term care settings, and community health centers resulting in changes to the clinical workflow to incorporate COVID-19 vaccine assessments, recommendations, and administration or referrals into routine office visits. Funded partners' activities improved COVID-19 vaccine access and addressed community concerns among racial and ethnic minority groups, as well as among people with barriers to vaccination due to chronic illness or disability, older age, lower income, or other factors.

An audit of the maternal medicine clinic: Cancer and pregnancy.

AIMS: To explore the incidence and complexity of women presenting for maternity care who require concurrent cancer care, and to report the birth outcomes of these women. MATERIALS AND METHODS: A retrospective audit of women attending a 'high risk' maternal medicine clinic at an Australian tertiary maternity hospital between 1 October 2021 and 30 April 2023 was conducted. The inclusion criteria were a diagnosis of cancer and a concurrent pregnancy, or a diagnosis of cancer prior to the current pregnancy. Clinic lists and coding data were screened via the electronic medical record to identify potential subjects. Data were collected from the individual maternity and neonatal records. RESULTS: Forty of 705 (5.7%) women attending the maternal medicine clinic met the inclusion criteria, of which ten had a new diagnosis of cancer in pregnancy and 30 presented for maternity care after a previous diagnosis of cancer. Cancer therapy during pregnancy included surgery and chemotherapy. Most pregnancies (92.5%) resulted in term deliveries (≥37 weeks gestation). Four neonates were preterm, and one was small-for-gestational-age. Caesarean section delivery and post-partum haemorrhage were more common than expected, but the rate of other adverse pregnancy outcomes was consistent with the background population. Over half of neonates required neonatal intensive care unit / special care nursery admission but the indications for admission were common, self-limiting conditions, and the length of stay was short (mean <5.0 days). CONCLUSIONS: Approximately 6% of women attending the maternal medicine clinic had a current or previous diagnosis of cancer. Most pregnancies resulted in term deliveries and neonatal outcomes were excellent.

What does competently delivered neuropsychological assessment feedback look like? Development and validation of a competency evaluation tool.

Objective: Neuropsychological assessment (NP) feedback helps patients and caregivers understand assessment results to maximise their utility and impact in everyday life. Yet feedback practices are inconsistent and there are no evidence-based guidelines for how feedback should be most effectively delivered. The aim of our study was to develop a psychometrically sound feedback competency checklist, the Psychology Competency Assessment Tool - Feedback (PsyCET-F), for use in research, training, and clinical settings. Method: The Delphi method of expert consensus was used to establish checklist items that clearly described competencies important for NP feedback. To examine the inter-rater reliability of the checklist, two experienced neuropsychologists rated the competencies demonstrated by trainee neuropsychologists across four feedback sessions. Results: After two Delphi rounds, consensus was reached on the 20-item checklist. Consensus was defined as at least 80% agreement amongst the panel of 20 experts. Four item categories resulted from the Delphi: (a) Opening the Session; (b) Applying Specific Feedback Techniques; (c) Engagement, Collaboration, and Alliance; and (d) Structuring and Ending the Session. Inter-rater reliability was moderate (κW = 0.79, p <.001, 80.52% agreement) when using a simple coding system, coded as Beginner, Intermediate, Competent, and Skilful; and strong (κW = 0.82, p <.001) when competency level was coded using an 8-point, detailed coding method. Conclusions: The PsyCET-F is psychometrically sound and fit-for-purpose for measuring competencies in giving NP feedback. It can be used in the training of clinicians to develop effective feedback skills. International benchmarking and usability testing will be conducted in a future study.

Collaborative depression care sensitive to the needs of underserved patients with cancer: Feasibility, acceptability and outcomes.

PURPOSE: A single-arm trial evaluated the feasibility, acceptability, and outcomes of COPE-D, a collaborative care intervention for underserved cancer patients with depression. METHODS: Bilingual (Spanish and English) care managers provided counseling and/or medication management in consultation with physicians. Outcomes were treatment improvement (≥ 5-point reduction in PHQ-9), treatment response (≥ 50% reduction in PHQ-9), suicidal ideation resolution, and changes in depression (PHQ-9), anxiety (GAD-2), sleep disturbance (PSQI), global mental and physical health (PROMIS), social isolation (PROMIS), and qualitative feedback. RESULTS: 193 patients consented to participate. 165 initiated and 141 completed treatment, with 65% and 56% achieving treatment improvement and response, respectively. Outcomes did not differ by ethnicity (31% Hispanic), cancer stage (71% stages III-IV), income, or education. Suicidal ideation, depression, anxiety, sleep disturbance, and social isolation also improved. Qualitative feedback was largely positive. CONCLUSION: COPE-D improved depression and quality of life among underserved patients, with acceptable retention rates.

Adapting Connect for Health pediatric weight management program for telehealth in response to the COVID-19 pandemic.

BACKGROUND: To address the evolving needs and context changes due to the COVID-19 pandemic, we adapted Connect for Health, an evidence-based, primary care, pediatric weight management intervention. The objective of this study is to describe the planned adaptation process to ensure continued and equitable program uptake during the pandemic. METHODS: Guided by adaptation frameworks, we identified the core functions and forms of Connect for Health and then adapted the intervention in response to a changing healthcare context. We engaged stakeholders and surveyed parents of children with a BMI ≥ 85th percentile and pediatric clinicians and examined their experiences using telehealth for pediatric weight management and needs and preferences. Using multivariable logistic regression, we examined the preferences of parents with limited English proficiency regarding key aspects of pediatric weight management. RESULTS: We surveyed 200 parents and 43% had a primary language of Spanish. Parents wanted care to be a combination of in-person and virtual visits (80%). We found that parents with limited English proficiency had a higher odds ratio of affirming in-person visits are better than virtual visits for ensuring their child's health concern can be taken care of (OR: 2.91; 95% CI: 1.36, 6.21), feeling comfortable when discussing personal information (OR: 3.91; 95% CI: 1.82, 8.43), talking about healthy behaviors and setting goals (OR: 3.09; 95% CI: 1.39, 6.90), and talking about mental health and overall well-being (OR: 4.02; 95% CI: 1.83, 8.87) than parents without limited English proficiency. We surveyed 75 clinicians and 60% felt telehealth was a useful tool to provide care for pediatric weight management. Clinicians felt virtual visits did not pose barriers to all aspects of care. Informed by the surveys and stakeholder input, we made clinician- and family-level adaptations while retaining the program's function. CONCLUSIONS: By engaging stakeholders and adapting the program for telehealth, we optimized the reach and fit of Connect for Health to ensure its continued uptake. We have provided a real-world example of how clinical innovations can evolve and how to systematically plan adaptations in response to changing healthcare contexts.

Microwave imaging for monitoring breast cancer treatment: A pilot study.

BACKGROUND: Microwave imaging has been proposed for medical applications, creating maps related to water content of tissues. Breast imaging has emerged as a key application because the signals can be coupled directly into the breast and experience limited attenuation in fatty tissues. While the literature contains reports of tumor detection with microwave approaches, there is limited exploration of treatment monitoring. PURPOSE: This study aims to detect treatment-related changes in breast tissue with a low-resolution microwave scanner. METHODS: Microwave scans of 15 patients undergoing treatment for early-stage breast cancer are collected at up to 4 time points: after surgery (baseline), 6 weeks after accelerated partial breast radiation, as well as 1 and 2 years post-treatment. Both the treated and untreated breast are scanned at each time point. The microwave scanner consists of planar transmit and receive arrays and uses signals from 0.1 to 10 GHz. The average microwave frequency properties (permittivity) are calculated for each scan to enable quantitative comparison. Baseline and 6-week results are analyzed with a two-way ANOVA with blocking. RESULTS: Consistent properties are observed for the untreated breast over time, similar to a previous study. Comparison of the scans of the treated and untreated breast suggests increased properties related to treatment, particularly at baseline and 6-weeks following radiotherapy. Analysis of the average properties of the scans with ANOVA indicates statistically significant differences ( p < 0.05 $p < 0.05$ ) in the treated and untreated breast at these time points. CONCLUSIONS: Microwave imaging has the potential to track treatment-related changes in breast tissues.

Incidence of 'Low-Risk but Not No-Risk' Features of Cancer Prior to High-Risk Feature Occurrence: An Observational Cohort Study in Primary Care.

Diagnosing cancer may be expedited by decreasing referral risk threshold. Clinical Practice Research Datalink participants (≥40 years) had a positive predictive value (PPV) ≥3% feature for breast, lung, colorectal, oesophagogastric, pancreatic, renal, bladder, prostatic, ovarian, endometrial or laryngeal cancer in 2016. The numbers of participants with features representing a 1-1.99% or 2-2.99% PPV for same cancer in the previous year were reported, alongside the time difference between meeting the ≥3% criteria and the lower threshold criteria. A total of 8616 participants had a PPV ≥3% feature, of whom 365 (4.2%) and 1147 (13.3%), respectively, met 2-2.99% and 1-1.99% criteria in the preceding year. The median time difference was 131 days (Interquartile Range (IQR) 27 to 256) for the 2-2.99% band and 179 days (IQR 58 to 289) for the 1-1.99% band. Results were heterogeneous across cancer sites. For some cancers, participants may progress from presenting lower- to higher-risk features before meeting urgent referral criteria; however, this was not usually the case. The details of specific features across multiple cancer sites will allow for a tailored approach to future reductions in referral thresholds, potentially improving the efficiency of urgent cancer referrals for the benefit both of individuals and the National Health Service (NHS).

Droplet Tn-Seq identifies the primary secretion mechanism for yersiniabactin in Yersinia pestis.

Nutritional immunity includes sequestration of transition metals from invading pathogens. Yersinia pestis overcomes nutritional immunity by secreting yersiniabactin to acquire iron and zinc during infection. While the mechanisms for yersiniabactin synthesis and import are well-defined, those responsible for yersiniabactin secretion are unknown. Identification of this mechanism has been difficult because conventional mutagenesis approaches are unable to inhibit trans-complementation by secreted factors between mutants. To overcome this obstacle, we utilized a technique called droplet Tn-seq (dTn-seq), which uses microfluidics to isolate individual transposon mutants in oil droplets, eliminating trans-complementation between bacteria. Using this approach, we first demonstrated the applicability of dTn-seq to identify genes with secreted functions. We then applied dTn-seq to identify an AcrAB efflux system as required for growth in metal-limited conditions. Finally, we showed this efflux system is the primary yersiniabactin secretion mechanism and required for virulence during bubonic and pneumonic plague. Together, these studies have revealed the yersiniabactin secretion mechanism that has eluded researchers for over 30 years and identified a potential therapeutic target for bacteria that use yersiniabactin for metal acquisition.

Individual variation in preference behavior in sailfin fish refines the neurotranscriptomic pathway for mate preference.

Social interactions can drive distinct gene expression profiles which may vary by social context. Here we use female sailfin molly fish (Poecilia latipinna) to identify genomic profiles associated with preference behavior in distinct social contexts: male interactions (mate choice) versus female interactions (shoaling partner preference). We measured the behavior of 15 females interacting in a non-contact environment with either two males or two females for 30 min followed by whole-brain transcriptomic profiling by RNA sequencing. We profiled females that exhibited high levels of social affiliation and great variation in preference behavior to identify an order of magnitude more differentially expressed genes associated with behavioral variation than by differences in social context. Using a linear model (limma), we took advantage of the individual variation in preference behavior to identify unique gene sets that exhibited distinct correlational patterns of expression with preference behavior in each social context. By combining limma and weighted gene co-expression network analyses (WGCNA) approaches we identified a refined set of 401 genes robustly associated with mate preference that is independent of shoaling partner preference or general social affiliation. While our refined gene set confirmed neural plasticity pathways involvement in moderating female preference behavior, we also identified a significant proportion of discovered that our preference-associated genes were enriched for 'immune system' gene ontology categories. We hypothesize that the association between mate preference and transcriptomic immune function is driven by the less well-known role of these genes in neural plasticity which is likely involved in higher-order learning and processing during mate choice decisions.

WHAM-A Prospective Study of Weight and Body Composition After Risk-Reducing Bilateral Salpingo-oophorectomy.

CONTEXT: Body weight and composition may change over the natural menopause transition. Whether surgical menopause has similar effects, and the impact of hormone replacement therapy (HRT), are unknown. Understanding the metabolic effects of surgical menopause will inform clinical care. OBJECTIVE: To prospectively measure weight and body composition over 24 months following surgical menopause compared with a similar comparison group who retained their ovaries. METHODS: Prospective observational study of weight change from baseline to 24 months in 95 premenopausal women at elevated risk of ovarian cancer planning risk-reducing salpingo-oophorectomy (RRSO) and 99 comparators who retained their ovaries. Change in body composition from baseline to 24 months was also assessed by dual-energy x-ray absorptiometry in a subgroup of 54 women who underwent RRSO and 81 comparators who retained their ovaries. In the subgroup, weight, fat mass, lean mass, and abdominal fat measures were compared between groups. RESULTS: At 24 months both groups had gained weight (RRSO 2760 ± 4860 g vs comparators 1620 ± 4540 g) with no difference between groups (mean difference 730 g; 95% CI 920 g to 2380 g; P = .383). In the body composition subgroup, there was no difference in weight between groups at 24 months (mean difference 944 g; 95% CI -1120 g to 2614 g; P = .431). RRSO women may have gained slightly more abdominal visceral adipose tissue (mean difference 99.0 g; 95% CI 8.8 g to 189.2 g; P = .032) but there were no other differences in body composition. There were also no differences in weight or body composition between HRT users and nonusers at 24 months. CONCLUSION: 24 months after RRSO, there was no difference in body weight compared with women who retained their ovaries. RRSO women gained more abdominal visceral adipose tissue than comparators, but there were no other differences in body composition. Use of HRT following RRSO had no effect on these outcomes.

Interviews with Indigenous Maori with type 1 diabetes using open-source automated insulin delivery in the CREATE randomised trial.

Purpose: Open-source automated insulin delivery (AID) is used by thousands of people with type 1 diabetes (T1D), but has unknown generalisability to marginalised ethnic groups. This study explored experiences of Indigenous Maori participants in the CREATE trial with use of an open-source AID system to identify enablers/barriers to health equity. Methods: The CREATE randomised trial compared open-source AID (OpenAPS algorithm on an Android phone with a Bluetooth-connected pump) to sensor-augmented pump therapy. Kaupapa Maori Research methodology was used in this sub-study. Ten semi-structured interviews with Maori participants (5 children, 5 adults) and whanau (extended family) were completed. Interviews were recorded and transcribed, and data were analysed thematically. NVivo was used for descriptive and pattern coding. Results: Enablers/barriers to equity aligned with four themes: access (to diabetes technologies), training/support, operation (of open-source AID), and outcomes. Participants described a sense of empowerment, and improved quality of life, wellbeing, and glycaemia. Parents felt reassured by the system's ability to control glucose, and children were granted greater independence. Participants were able to use the open-source AID system with ease to suit whanau needs, and technical problems were manageable with healthcare professional support. All participants identified structures in the health system precluding equitable utilisation of diabetes technologies for Maori. Conclusion: Maori experienced open-source AID positively, and aspired to use this therapy; however, structural and socio-economic barriers to equity were identified. This research proposes strength-based solutions which should be considered in the redesign of diabetes services to improve health outcomes for Maori with T1D.Trial Registration: The CREATE trial, encompassing this qualitative sub-study, was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12620000034932p) on the 20th January 2020. Supplementary Information: The online version contains supplementary material available at 10.1007/s40200-023-01215-3.

Tobacco use and cancer-related symptom burden: Analysis of the US Population Assessment of Tobacco and Health Study.

BACKGROUND: Understanding the relationship between tobacco use and symptom burden may inform tobacco treatment interventions tailored to the needs of individuals with cancer. METHODS: The study included 1409 adult cancer survivors from Wave 5 of the US Food and Drug Administration Population Assessment of Tobacco and Health (PATH) Study. A multivariate analysis of variance controlling for age, sex, and race/ethnicity assessed the association of cigarette smoking and vaping on cancer-related symptom burden (fatigue, pain, emotional problems) and quality of life (QoL). Generalized linear mixed models controlling for the same factors were used to assess associations among symptom burden, QoL, and quit-smoking intentions, quit-smoking likelihood, and past 12-month smoking quit attempts. RESULTS: Weighted rates of current cigarette smoking and vaping were 14.21% and 2.88%, respectively. Current smoking was associated with greater fatigue (p < .0001; partial η 2  = .02), pain (p < .0001; partial η 2  = .08), emotional problems (p < .0001; partial η 2  = .02), and worse QoL (p < .0001; partial η 2  = .08). Current vaping was associated with greater fatigue (p = .001; partial η 2  = .008), pain (p = .009; partial η 2  = .005), and emotional problems (p = .04; partial η 2  = .003), but not worse QoL (p = .17). Higher cancer symptom burden was not associated with reduced interest in quitting, likelihood of quitting, or odds of past year quit attempts (p > .05 for each). CONCLUSIONS: Among adults with cancer, current smoking and vaping were associated with greater symptom burden. Survivors' interest in and intentions to quit smoking were not related to symptom burden. Future research should examine the role of tobacco cessation in improving symptom burden and QoL.

Folate Supplementation in Women with Pre-Existing Diabetes.

Folate supplementation in the periconceptual period is the standard of care for the prevention of neural tube defects. To support dietary folate intake, some countries have introduced mandatory folic acid fortification of food products. Robust evidence supports the additional use of a low-dose folic acid supplement (0.4 mg/day) in all women from 2-3 months preconception until the end of the 12th week of gestation. For women with pre-existing diabetes, high-dose folic acid supplementation (5 mg/day) is recommended in some, but not all international guidelines. The recommendation is made based on consensus opinion and reflects the increased risk of neural tube defects in pregnant women with pre-existing diabetes. However, there is limited evidence to clarify the high-risk groups that benefit from high-dose folic acid versus those that do not. There are also some data to suggest that high-dose folic acid may be harmful to mothers and offspring, although this issue remains controversial. This narrative review explores the evidence that supports the recommendation for women with pre-existing diabetes to take high-dose folic acid in the periconceptual period. It explores the potential benefits of high-dose supplemental folate beyond the prevention of neural tube defects, and also the potential adverse impacts of high-dose folate use. These topics are considered with a specific focus on the issues that are pertinent to women with pre-existing diabetes. Based on the available evidence, a pragmatic approach to the use of folic acid supplements in women with pre-existing diabetes during the periconception period is suggested. The need for comprehensive preconception care that optimises glycaemic control and addresses other modifiable risk factors before pregnancy is emphasized.

Perception and Counseling for Cardiac Health in Breast Cancer Survivors.

Context: Breast cancer survivors have increased cardiovascular disease (CVD) risk compared to those without cancer history. CVD is the leading cause of death for breast cancer survivors. Objective: To assess current CVD risk counseling practices and risk perception in breast cancer survivors. Study design and analysis: Interviews conducted with breast cancer survivors. Analysis of categorical data by frequency and quantitative variables by mean and standard deviation. Inductive qualitative analysis performed using NVIVO. Setting: Academic Family Medicine Outpatient Practices Population studied: Breast cancer survivors with an identified primary care provider. Intervention/instrument: Interviews on CVD risk behaviors, risk perception, challenges with risk reduction, and previous history of risk counseling. Outcome measures: Self-reported history of CVD, risk perception, and risk behaviors. Results: The average age of participants (n=19) was 57 with 57% being white and 32% African American. Of interviewed women, 89.5% reported a personal history and 89.5% reported a family history of CVD. Only 52.6% had previously reported receipt of CVD counseling. Primary care providers most commonly provided the counseling (72.7%), however it was additionally provided by oncology (27.3%). Among breast cancer survivors, 31.6% perceived they were at increased CVD risk and 47.5% were unsure of their relative CVD risk compared to women their age. Factors affecting perceived CVD risk included family history, cancer treatments, cardiovascular diagnoses, and lifestyle factors. Video (78.9%) and text messaging (68.4%) were the most highly reported mechanisms through which breast cancer survivors requested to receive additional information and counseling on CVD risk and risk reduction. Commonly reported barriers to adopting risk reduction strategies (such as increasing physical activity) included time, resources, physical limitations, and competing responsibilities. Barriers specific to survivorship status include concerns for immune status during COVID, physical limitations associated with cancer treatment, and psychosocial aspects of cancer survivorship. Conclusions: These data suggest improving the frequency and content of CVD risk reduction counseling is needed. Strategies should identify the best methods for providing CVD counseling, and should address general barriers as well as unique challenges faced by cancer survivors.
