Germline ERG haploinsufficiency defines a new syndrome with cytopenia and hematological malignancy predisposition.

The genomics era has facilitated discovery of new genes predisposing to bone marrow failure (BMF) and hematological malignancy (HM). We report the discovery of ERG as a novel autosomal dominant BMF/HM predisposition gene. ERG is a highly constrained transcription factor critical for definitive hematopoiesis, stem cell function and platelet maintenance. ERG colocalizes with other transcription factors including RUNX1 and GATA2 on promoters/enhancers of genes orchestrating hematopoiesis. We identified a rare heterozygous ERG missense variant in 3 thrombocytopenic individuals from one family and 14 additional ERG variants in unrelated individuals with BMF/HM including 2 de novo cases and 3 truncating variants. Phenotypes associated with pathogenic germline ERG variants included cytopenias (thrombocytopenia, neutropenia, pancytopenia) and HMs (acute myeloid leukemia, myelodysplastic syndrome, acute lymphoblastic leukemia) with onset before 40 years. Twenty ERG variants (19 missense, 1 truncating) including 3 missense population variants were functionally characterized. Thirteen potentially pathogenic ETS domain missense variants displayed loss-of-function characteristics disrupting transcriptional transactivation, DNA-binding and/or nuclear localization. Selected variants overexpressed in mouse fetal liver cells failed to drive myeloid differentiation and cytokine-independent growth in culture, and to promote acute erythroleukemia when transplanted into mice, concordant with these variants being loss-of-function. Four individuals displayed somatic genetic rescue by copy neutral loss of heterozygosity. Identification of predisposing germline ERG variants has clinical implications for patient/family diagnosis, counselling, surveillance, and treatment strategies including selection of bone marrow donors or cell/gene therapy.

Novel modes of MPL activation in triple-negative myeloproliferative neoplasms.

The identification of a somatic mutation associated with myeloid malignancy is of diagnostic importance in myeloproliferative neoplasms (MPNs). Individuals with no mutation detected in common screening tests for variants in JAK2, CALR, and MPL are described as 'triple-negative' and pose a diagnostic challenge if there is no other evidence of a clonal disorder. To identify potential drivers that might explain the clinical phenotype, we used an extended sequencing panel to characterise a cohort of 44 previously diagnosed triple-negative MPN patients for canonical mutations in JAK2, MPL and CALR at low variant allele frequency (found in 4/44 patients), less common variants in the JAK-STAT signalling pathway (12 patients), or other variants in recurrently mutated genes from myeloid malignancies (18 patients), including hotspot variants of potential clinical relevance in eight patients. In one patient with thrombocytosis we identified biallelic germline MPL variants. Neither MPL variant was activating in cell proliferation assays, and one of the variants was not expressed on the cell surface, yet co-expression of both variants led to thrombopoietin hypersensitivity. Our results highlight the clinical value of extended sequencing including germline variant analysis and illustrate the need for detailed functional assays to determine whether rare variants in JAK2 or MPL are pathogenic.

Factors Impacting the Decision of an Individual With Lynch Syndrome to Terminate a Health Care Provider Relationship.

Lynch syndrome (LS) is a genetic cancer syndrome that puts affected individuals at a significantly higher risk of developing multiple cancers. Participants (n = 57) were recruited through social media. Data were collected through online surveys and phone interviews; the interview data (n = 55) were analyzed to identify provider terminations and the factors that motivated these decisions. Results indicate that individuals with LS terminated their patient-provider relationships due to lack of provider LS knowledge, poor interactions, or a combination of both factors. Findings from this study suggest a need for better interactions between LS patients and providers and increased knowledge of LS-specific care.

Targeted gene panels identify a high frequency of pathogenic germline variants in patients diagnosed with a hematological malignancy and at least one other independent cancer.

The majority of studies assessing the contribution of pathogenic germline variants (PGVs) to cancer predisposition have focused on patients with single cancers. We analyzed 45 known cancer predisposition genes (CPGs) in germline samples of 202 patients with hematological malignancies (HMs) plus one or more other independent cancer managed at major tertiary medical centers on two different continents. This included 120 patients with therapy-related myeloid neoplasms (t-MNs), where the HM occurred after cytotoxic treatment for a first malignancy, and 82 patients with multiple cancers in which the HM was not preceded by cytotoxic therapy (MC-HM). Using American College of Medical Genetics/Association for Molecular Pathology variant classification guidelines, 13% of patients had PGVs, most frequently identified in CHEK2 (17% of PGVs), BRCA1 (13%), DDX41 (13%), and TP53 (7%). The frequency of PGVs in MC-HM was higher than in t-MN, although not statistically significant (18 vs. 9%; p = 0.085). The frequency of PGVs in lymphoid and myeloid HM patients was similar (19 vs. 17.5%; p > 0.9). Critically, patients with PGVs in BRCA1, BRCA2 or TP53 did not satisfy current clinical phenotypic criteria for germline testing. Our data suggest that a personal history of multiple cancers, one being a HM, should trigger screening for PGVs.

Data models, representation and adequacy-for-purpose.

We critically engage two traditional views of scientific data and outline a novel philosophical view that we call the pragmatic-representational (PR) view of data. On the PR view, data are representations that are the product of a process of inquiry, and they should be evaluated in terms of their adequacy or fitness for particular purposes. Some important implications of the PR view for data assessment, related to misrepresentation, context-sensitivity, and complementary use, are highlighted. The PR view provides insight into the common but little-discussed practices of iteratively reusing and repurposing data, which result in many datasets' having a phylogeny-an origin and complex evolutionary history-that is relevant to their evaluation and future use. We relate these insights to the open-data and data-rescue movements, and highlight several future avenues of research that build on the PR view of data.

Medication management in dialysis: Barriers and strategies.

People with end-stage kidney disease (ESKD) who require chronic dialysis are often reliant on complicated medication regimens to manage their health conditions. Due to the complexities of the advanced kidney disease, underlying comorbidities, and special instructions, medication regimens for patients on dialysis put patients at high risk for medication therapy problems related to safety, effectiveness, appropriateness, and adherence. This article explores the factors that affect optimal medication use for people on dialysis, including the broader drug use system, and offers recommendations around medication reconciliation, medication review, deprescribing, and considering social determinants of health to improve medication management among patients with ESKD.

Assessment of literacy and numeracy skills related to medication labels in patients on chronic in-center hemodialysis.

OBJECTIVES: Patients on hemodialysis have complicated medication regimens requiring the ability to accurately interpret medication information. Literacy and numeracy skills have been shown to differ by the types of materials provided to patients. The aims of this study were to determine prescription and over-the-counter medication label understanding and to assess the prevalence of low health literacy regarding medication labeling among in-center hemodialysis patients. DESIGN, SETTING AND PARTICIPANTS: The Medication Literacy and Numeracy in Dialysis (MedLitD) tool is an assessment of a person's ability to read and understand medication labels. A comparison with the Rapid Estimate of Adult Literacy in Medicine Short Form (REALM-SF), an established literacy tool, was conducted to determine if there were differences in the literacy results from the 2 tools that could be leveraged to target education initiatives for this specialized population. RESULTS: A total of 110 patients receiving hemodialysis from 3 dialysis facilities in the Capital Region of upstate New York were enrolled in the study. Most patients (77%) achieved a maximum REALM-SF score, indicating a high level of literacy proficiency; however, their MedLitD scores varied. Patients who were 65 years and older had lower scores on the MedLitD tool compared with younger patients. Gender, education, and the number of medications did not influence the MedLitD scores. Only 16% of all participants correctly answered the question asking for an indication of the phosphate binder (PB), although the most patients were currently taking PBs. CONCLUSION: A continuum of medication literacy levels exists among patients on hemodialysis. Appropriate evaluation of medication literacy should be done to better inform individualized education and counseling.

Health and lifestyle behaviors in colorectal cancer survivors with and without Lynch syndrome.

Lynch syndrome (LS), a hereditary cancer syndrome, accounts for approximately 3% of colorectal cancers (CRC). Positive health behaviors and surveillance are preventive strategies, but research on whether recommended behavioral guidelines are followed by individuals with LS is limited. Additional health education and promotion could be beneficial to the improved survivorship of CRC survivors. Explore health and lifestyle behaviors in CRC survivors with and without LS. We conducted a case-control study of CRC survivors with and without LS using a mailed questionnaire. Recruitment was conducted via patient registries at The University of Texas MD Anderson Cancer Center (cases n = 33; controls n = 75) and through social media (cases n = 42). CRC survivors with and without LS in our study had substantially lower smoking prevalence (5.5% and 2.7%) compared to national prevalence (18.0%). However, they had higher levels of alcohol consumption (36.8% and 10.3% for male and female LS survivors, respectively, and 35.8% and 22.0% for male and female sporadic survivors, respectively) compared to national prevalence of 13.88% for males and 6.02% for females. Both groups of CRC survivors participate in negative health behaviors that impact survivorship. More research is needed to examine the relationship between personal engagement in preventive behaviors and patient-provider relationships to improve health behaviors and explore strategies for intervention. Additionally, better health education and lifestyle change recommendations would promote and reinforce positive health outcomes in the CRC population and especially in LS survivors.

For Women, Lynch Syndrome Is About More than Colon Cancer.

Lynch syndrome, also known as hereditary nonpolyposis colorectal cancer, has historically been characterized by a predisposition to colorectal cancer; however, for women with Lynch syndrome, the risks for gynecologic cancers pose an equal or greater risk than colorectal cancer. In addition, the gynecologic cancer is often the first cancer that presents in these patients. Also of importance to women with Lynch syndrome is the efficacy of gynecologic cancer screening being significantly lower than colorectal cancer screening, leading to inconsistency in provider recommendations for gynecologic screening and surveillance. We had the chance to listen to women with Lynch syndrome, in their own words, discuss their health care experiences as they relate to gynecologic cancer risk, and identified several important themes. They describe feeling confused about their screening and surveillance options while also being heavily reliant on their health care providers for guidance. In addition, women with Lynch syndrome discuss attempting to balance medical management of Lynch syndrome with their reproductive choices. Finally, they believe that increased awareness by women and their providers about the gynecologic cancer risks associated with Lynch syndrome should be a higher priority. We view the words of these women as a call to action for Lynch syndrome patients, clinicians, researchers, and advocates.

The mutational burden of therapy-related myeloid neoplasms is similar to primary myelodysplastic syndrome but has a distinctive distribution.

Therapy-related myeloid neoplasms (T-MN) are poorly characterized secondary hematological malignancies following chemotherapy/radiotherapy exposure. We compared the clinical and mutational characteristics of T-MN (n = 129) and primary myelodysplastic syndrome (P-MDS, n = 108) patients. Although the somatic mutation frequency was similar between T-MN and P-MDS patients (93% in both groups), the pattern was distinct. TP53 mutations were more frequent in T-MN (29.5 vs. 7%), while spliceosomal complex mutations were more common in P-MDS (56.5 vs. 25.6%). In contrast to P-MDS, the ring sideroblasts (RS) phenotype was not associated with better survival in T-MN, most probably due to genetic association with TP53 mutations. SF3B1 was mutated in 96% of P-MDS with ≥15% RS, but in only 32% T-MN. TP53 mutations were detected in 92% T-MN with ≥15% RS and SF3B1 wild-type cases. Interestingly, T-MN and P-MDS patients with "Very low" or "Low" Revised International Prognostic Scoring System (IPSS-R) showed similar biological and clinical characteristics. In a Cox regression analysis, TP53 mutation was a poor prognostic factor in T-MN, independent of IPSS-R cytogenetics, disease-modifying therapy, and NRAS mutation. Our data have direct implications for T-MN management and provide evidence that, in addition to conventional disease parameters, mutational analysis should be incorporated in T-MN risk stratification.

De novo UBE2A mutations are recurrently acquired during chronic myeloid leukemia progression and interfere with myeloid differentiation pathways.

Despite the advent of tyrosine kinase inhibitors, a proportion of chronic myeloid leukemia patients in chronic phase fail to respond to imatinib or to second-generation inhibitors and progress to blast crisis. Until now, improvements in the understanding of the molecular mechanisms responsible for chronic myeloid leukemia transformation from chronic phase to the aggressive blast crisis remain limited. Here we present a large parallel sequencing analysis of 10 blast crisis samples and of the corresponding autologous chronic phase controls that reveals, for the first time, recurrent mutations affecting the ubiquitin-conjugating enzyme E2A gene (UBE2A, formerly RAD6A). Additional analyses on a cohort of 24 blast crisis, 41 chronic phase as well as 40 acute myeloid leukemia and 38 atypical chronic myeloid leukemia patients at onset confirmed that UBE2A mutations are specifically acquired during chronic myeloid leukemia progression, with a frequency of 16.7% in advanced phases. In vitro studies show that the mutations here described cause a decrease in UBE2A activity, leading to an impairment of myeloid differentiation in chronic myeloid leukemia cells.

Freezing fertility or freezing false hope? A content analysis of social egg freezing in U.S. print media.

In 2012, the American Society for Reproductive Medicine (ASRM) lifted the experimental label on oocyte preservation, but cautioned against women using it to avoid age-related infertility, known as social egg freezing (SEF). In 2014, Facebook and Apple announced that they would offer SEF as a workplace benefit. Within the context of a rapidly growing market for SEF, we were interested in how these two decisions affected media discussions, given that such discourse can strongly influence public perceptions and behaviors. We used a content analysis methodology to code 138 articles published in U.S. newspapers and magazines between 2012 and 2015. Focusing on a financial concern over the cost of SEF and the lack of insurance for SEF, we found that media portrayals of SEF pivot away from the ethical principle of nonmaleficence centered in the ASRM decision to discourage SEF. Instead, they highlight an issue of justice that can be remedied through the offer of SEF as a workplace benefit. Overall, media portrayals of SEF paint a simplistic and rosy picture that more options, especially more reproductive and economic options, automatically enhance women's autonomy.

Integrative genomic analysis reveals cancer-associated mutations at diagnosis of CML in patients with high-risk disease.

Genomic events associated with poor outcome in chronic myeloid leukemia (CML) are poorly understood. We performed whole-exome sequencing, copy-number variation, and/or RNA sequencing for 65 patients to discover mutations at diagnosis and blast crisis (BC). Forty-six patients with chronic-phase disease with the extremes of outcome were studied at diagnosis. Cancer gene variants were detected in 15 (56%) of 27 patients with subsequent BC or poor outcome and in 3 (16%) of 19 optimal responders (P = .007). Frequently mutated genes at diagnosis were ASXL1, IKZF1, and RUNX1 The methyltransferase SETD1B was a novel recurrently mutated gene. A novel class of variant associated with the Philadelphia (Ph) translocation was detected at diagnosis in 11 (24%) of 46 patients comprising fusions and/or rearrangement of genes on the translocated chromosomes, with evidence of fragmentation, inversion, and imperfect sequence reassembly. These were more frequent at diagnosis in patients with poor outcome: 9 (33%) of 27 vs 2 (11%) of 19 optimal responders (P = .07). Thirty-nine patients were tested at BC, and all had cancer gene variants, including ABL1 kinase domain mutations in 58%. However, ABL1 mutations cooccurred with other mutated cancer genes in 89% of cases, and these predated ABL1 mutations in 62% of evaluable patients. Gene fusions not associated with the Ph translocation occurred in 42% of patients at BC and commonly involved fusion partners that were known cancer genes (78%). Genomic analysis revealed numerous relevant variants at diagnosis in patients with poor outcome and all patients at BC. Future refined biomarker testing of specific variants will likely provide prognostic information to facilitate a risk-adapted therapeutic approach.

"How do I say that?": Using communication principles to enhance medication therapy management instruction.

BACKGROUND AND PURPOSE: Medication therapy management (MTM) is a comprehensive, patient-centered approach to improving medication use, reducing the risk of adverse events and improving medication adherence. Given the service delivery model and required outputs of MTM services, communication skills are of utmost importance. The objectives of this study were to identify and describe communication principles and instructional practices to enhance MTM training. EDUCATIONAL ACTIVITY AND SETTING: Drawing on formative assessment data from interviews of both pharmacy educators and alumni, this article identifies and describes communication principles and instructional practices that pharmacy educators can use to enhance MTM training initiatives to develop student communication strategies. FINDINGS: Analysis revealed five key communication challenges of MTM service delivery, two communication principles that pharmacy teachers and learners can use to address those challenges, and a range of specific strategies, derived from communication principles, that students can use when challenges emerge. Implications of the analysis for pharmacy educators and researchers are described. SUMMARY: Proactive communication training provided during MTM advanced pharmacy practice experiences enabled students to apply the principles and instructional strategies to specific patient interactions during the advanced pharmacy practice experiences and in their post-graduation practice settings.

Availability of information on young onset dementia for patients and carers in six European countries.

OBJECTIVES: To identify information available in six European countries (England, France, Germany, Netherlands, Portugal, Sweden) that addresses the specific needs of people with young onset dementia (YOD) and their carers, and identify gaps. METHODS: Search of websites of organisations with potential interest in dementia. Narrative synthesis and comparative analysis. RESULTS: 21 sources of information were identified (Netherlands 6, England 6, France 3, Germany 2, Portugal 2, Sweden 2); 11 were from voluntary sector organisations. Sources dedicated to YOD were limited (4 websites, 4 books); all other YOD information was sub-entries in generic dementia sources, difficult to locate and with limited coverage of relevant topics. Gaps related to implications of living with YOD in Germany, Portugal and Sweden. CONCLUSION: Availability of information varies among countries, some having no dedicated source and incomplete coverage of issues of importance to YOD. PRACTICAL IMPLICATIONS: Information is an important means of supporting carers; their needs change as the condition progresses. A comprehensive resource collating key information is needed so that the issues that differentiate the specific needs of people living with YOD from those of people with dementia in older age are available and easily located.

Experiential Education Builds Student Self-Confidence in Delivering Medication Therapy Management.

To determine the impact of advanced pharmacy practice experiences (APPE) on student self-confidence related to medication therapy management (MTM), fourth-year pharmacy students were surveyed pre/post APPE to: identify exposure to MTM learning opportunities, assess knowledge of the MTM core components, and assess self-confidence performing MTM services. An anonymous electronic questionnaire administered pre/post APPE captured demographics, factors predicted to impact student self-confidence (Grade point average (GPA), work experience, exposure to MTM learning opportunities), MTM knowledge and self-confidence conducting MTM using a 5-point Likert scale (1 = Not at all Confident; 5 = Extremely Confident). Sixty-two students (26% response rate) responded to the pre-APPE questionnaire and n = 44 (18%) to the post-APPE. Over 90% demonstrated MTM knowledge and 68.2% completed MTM learning activities. APPE experiences significantly improved students' overall self-confidence (pre-APPE = 3.27 (0.85 SD), post-APPE = 4.02 (0.88), p < 0.001). Students engaging in MTM learning opportunities had higher self-confidence post-APPE (4.20 (0.71)) vs. those not reporting MTM learning opportunities (3.64 (1.08), p = 0.05). Post-APPE, fewer students reported MTM was patient-centric or anticipated engaging in MTM post-graduation. APPE learning opportunities increased student self-confidence to provide MTM services. However, the reduction in anticipated engagement in MTM post-graduation and reduction in sensing the patient-centric nature of MTM practice, may reveal a gap between practice expectations and reality.

A comparison between Lynch syndrome and sporadic colorectal cancer survivors' satisfaction with their healthcare providers.

This study evaluated provider satisfaction in a sample of colorectal cancer (CRC) survivors with and without Lynch syndrome (LS). Participants were case-case-matched CRC survivors with (n = 75) or without (n = 75) LS (mean age of 55; range: 27-93). Participants completed a mailed questionnaire assessing demographics, clinical characteristics, healthcare utilization, psychosocial variables, and provider satisfaction. LS CRC survivors reported lower provider satisfaction scores on three subscales of the Primary Care Assessment Survey: communication (78.14 vs. 83.96; P < 0.05), interpersonal treatment (78.58 vs. 85.30; P < 0.05), and knowledge of the patient (60.34 vs. 69.86; P < 0.01). Among LS CRC survivors, predictors for mean communication and trust subscale scores were location of treatment and socioeconomic status. Higher mean depression scores also were associated with trust, while social support predicted higher satisfaction with communication. Sporadic CRC survivor satisfaction is driven largely by age (communication, interpersonal treatment) and patient anxiety (communication), while seeing a provider more often was associated with increased satisfaction with knowledge of the patient. LS CRC survivors reported lower levels of provider satisfaction than sporadic CRC survivors. LS survivors who received care at The University of Texas MD Anderson Cancer Center, a comprehensive cancer center (CCC), reported higher satisfaction than those receiving care at other institutions. Depressive symptoms and socioeconomic status may impact provider satisfaction ratings. Exploration of other potential predictors of provider satisfaction should be examined in this population. Additionally, further research is needed to examine the potential impact of provider satisfaction on adherence to medical recommendations in LS CRC survivors, particularly those being treated outside of CCCs.

The Use of Social Media to Recruit Participants With Rare Conditions: Lynch Syndrome as an Example.

BACKGROUND: Social media is increasingly being used as a means of recruiting participants, particularly for investigators whose areas of interest involve rare conditions or hard-to-reach populations. However, much of the literature to date has focused on paid advertisement recruitment. OBJECTIVE: We used Lynch syndrome (LS), a rare hereditary cancer syndrome, as a model to demonstrate the successful partnership between researchers and a Web-based patient education and advocacy organization to facilitate participant recruitment. METHODS: Recruitment was undertaken in partnership with Lynch Syndrome International (LSI), an advocacy organization with a strong social media presence. After LSI published our study information, participants followed up via email or phone call. Following prescreening and consent, interested and eligible participants were then sent a secure survey link. RESULTS: Within 36 hours of a single Facebook post by the site administrators for LSI, over 150 individuals responded via phone or email. Sixty-five individuals were sent the survey link and 57 individuals completed the survey (88% response rate). Of note, these 57 individuals were geographically diverse within the Unites States, representing LS patients from 26 different states. CONCLUSIONS: This approach has several advantages, including recruitment through a trusted source outside of a clinical setting, higher response rates, and cost-effectiveness with a small research team in a relatively short amount of time. Overall, social media recruitment with a trusted online partner can be highly effective in hard-to-reach clinical populations, such as patients with LS. However, this approach requires additional effort for eligibility screening.

Health-related quality of life in colorectal cancer survivors: are there differences between sporadic and hereditary patients?

PURPOSE: To compare health-related quality of life (HRQoL) in colorectal cancer (CRC) survivors with sporadic CRC to those with hereditary cancer, specifically Lynch syndrome (LS). METHODS: Participants completed a mailed self-administered questionnaire that assessed, among other things, demographics, clinical characteristics, and health-related quality of life. Using a case-case design, CRC survivors with LS or sporadic cancer were matched on age, sex, race/ethnicity, cancer stage, geography, and time since diagnosis. Participants were recruited from patient registries at The University of Texas MD Anderson Cancer Center (MD Anderson) (n = 33 LS; n = 75 sporadic) and through social media (n = 42 LS). The final sample included 71 LS and 74 sporadic CRC survivors. RESULTS: For LS patients, the mean FACT-C HRQoL score was 84.8 (11.9) [Median = 86.0; Interquartile Range-17] compared to sporadic patients mean score of 85.8 (16.7) [Median = 92.0; Interquartile Range-21], which indicates high quality of life for both groups. LS patients and sporadic CRC patients had similar HRQoL mean scores across 7 different HRQoL metrics, with no significant differences between groups. Exploratory regression analyses indicate some differences in known predictors of HRQoL by group despite no bivariate differences. CONCLUSIONS: HRQoL is an important component of survivorship in CRC patients. Given the clinical distinctions between LS and sporadic patients, we expected to find significant differences between these patients. However, the patients' experiences/quality of life does not appear to illustrate such a clear dissimilarity within CRC survivors. Given the limited data in this area, larger studies, ideally with data obtained from multiple sites, is needed to better investigate the alignment between clinical determination and patient experience as well as to explore the relationship between HRQOL, treatment regimens, and health outcomes.
