Project description:ImportanceVariant reclassification is an important component of hereditary cancer genetic testing; however, there are few published data quantifying the prevalence of reclassification.ObjectiveRetrospective cohort study of individuals who had genetic testing from 2006 through 2016 at a single commercial laboratory.Design, setting, and participantsA retrospective cohort of individuals who had genetic testing between 2006 and 2016 at a single commercial laboratory was assessed. Variants were classified as benign, likely benign, variant of uncertain significance, likely pathogenic, or pathogenic. Retrospective chart reviews were conducted for patients from the University of Texas Southwestern (UTSW) Medical Center.ExposuresHereditary cancer genetic testing.Main outcomes and measuresFrequency of and time to amended reports; frequency and types of variant reclassification.ResultsFrom 2006 through 2018, 1.45 million individuals (median [interquartile range] age at testing, 49 years [40.69-58.31 years], 95.6% women) had genetic testing, and 56.6% (n = 821 724) had a personal history of cancer. A total of 1.67 million initial tests were reported and 59 955 amended reports were issued due to variant reclassification. Overall, 6.4% (2868 of 44 777) of unique variants were reclassified. Reclassification to a different clinical category was rare among unique variants initially classified as pathogenic or likely pathogenic (0.7%, 61 of 9112) or benign or likely benign (0.2%, 15 of 8995). However, 7.7% (2048 of 26 670) of unique variants of uncertain significance were reclassified: 91.2% (1867 of 2048) were downgraded to benign or likely benign (median time to amended report, 1.17 years), 8.7% (178 of 2048) were upgraded to pathogenic or likely pathogenic variants (median time to amended report, 1.86 years). Because most variants were observed in more than 1 individual, 24.9% (46 890 of 184 327) of all reported variants of uncertain significance were reclassified.Conclusions and relevanceFollowing hereditary cancer genetic testing at a single commercial laboratory, 24.9% of variants of uncertain significance were reclassified, which included both downgrades and upgrades. Further research is needed to assess generalizability of the findings for other laboratories, as well as the clinical consequences of the reclassification as a component of a genetic testing program.

Project description:The Family Perceptions of Physician-Family Caregiver Communication scale (FPPFC) was developed to assess quality of physician-family end-of-life communication in nursing homes. However, its validity has been tested only in the USA and the Netherlands. The aim of this paper is to evaluate the FPPFC construct validity and its reliability, as well as the psychometric characteristics of the items comprising the scale. Data were collected in cross-sectional study in Belgium, Finland, Italy, the Netherlands and Poland. The factorial structure was tested in confirmatory factor analysis. Item parameters were obtained using an item response theory model. Participants were 737 relatives of nursing home residents who died up to 3 months prior to the study. In general, the FPPFC scale proved to be a unidimensional and reliable measure of the perceived quality of physician-family communication in nursing home settings in all five countries. Nevertheless, we found unsatisfactory fit to the data with a confirmatory model. An item that referred to advance care planning performed less well in Poland and Italy than in the Northern European countries. In the item analysis, we found that with no loss of reliability and with increased coherency of the item content across countries, the full 7-item version can be shortened to a 4-item version, which may be more appropriate for international studies. Therefore, we recommend use of the brief 4-item FPPFC version by nursing home managers and professionals as an evaluation tool, and by researchers for their studies as these four items confer the same meaning across countries.Supplementary informationThe online version contains supplementary material available at 10.1007/s10433-022-00742-x.

Project description:ObjectiveThis research explored health sciences librarians' perceptions of intergenerational communication in the workplace.MethodsThe authors developed and sent a survey to health sciences librarians through email discussion lists from August 2018 to September 2018. A chi-square test was performed to determine whether one's length of employment as a librarian was associated with belief that age and/or generation impacts communication in the workplace.ResultsA total of 150 respondents from 5 countries completed the survey. There was no significant association between length of employment as a librarian and respondents' belief that age and/or generation impacts communication in the workplace. However, regardless of length of employment, most respondents indicated that generational differences do have an impact on communication in the workplace. Also, most respondents expressed interest in institutional initiatives to foster intergenerational communication.ConclusionThe authors found that health sciences librarians believe that differences among generations impact communication in the workplace. Librarians, managers, and library organizations should consider providing training and other opportunities for health sciences librarians to improve their intergenerational communication skills.

Project description:To describe the study methods, baseline characteristics and burden of study procedures of an intervention designed to reduce family stress symptoms through early support from the palliative care team. Length of stay of ?8days was the trigger for early palliative care involvement.Cluster-randomized trial with children as the unit of randomization. Up to 3 family members per child were recruited. Family stress symptoms were recorded at baseline, discharge from the ICU, and 3months post-enrollment. Questionnaire burden was assessed on a 1-10 point scale at each time point and open-ended comments were analyzed to describe the participants' experience in the study.380 family members of 220 children (control=115 children and 204 family members; intervention=105 children and 176 family members) were recruited, which represented 50% of all eligible families. Most family participants were parents (86% control; 92% intervention) and female (66% both groups). Retention rates were high through the 3-month follow-up: 93% and 90% for the control and intervention groups respectively. Questionnaire burden was very low: mean (sd) scores were 1.1 (1.6), 0.7 (1.5), and 0.9 (1.6) for the baseline, discharge and follow-up questionnaires, respectively. Comments suggest that participation was beneficial by promoting reflection and self-awareness about stress, coping and resilience, and feeling cared for because the intervention and questionnaires focused on their own well-being.The participants' comments regarding the focus on them as the point of intervention reflects the value of conducting research with family members of seriously ill children during ICU stays.

Project description:This research uses grounded theory to assess the driving needs of 29 older car drivers using four data collection techniques (two waves of focus groups, an interview and a driver diary). Findings suggest that older drivers view themselves as having better driving skills and attitude towards driving compared to when they were younger and compared to other drivers. In addition, they have a good ability to adapt to their changing physiology. Nevertheless, they report difficulty in assessing their own driving ability and cite they would like help to increase self-awareness about the driving task. In addition, the participants report having increasing difficulty in not having enough time to read, compute and comprehend road signs, maintaining a constant speed at the speed-limit, increased tiredness and fatigue and increased sensitivity to glare. The findings suggest given an iterative, qualitative methodology where driving issues are focused upon, older drivers can become more self-aware of their driving limitations and discuss these aspects in the context of ageing physiology.

Project description:ImportanceIncentivizing research participation is controversial and variably regulated because of uncertainty regarding whether financial incentives serve as undue inducements by diminishing peoples' sensitivity to research risks or unjust inducements by preferentially increasing enrollment among underserved individuals.ObjectiveTo determine whether incentives improve enrollment in real randomized clinical trials (RCTs) or serve as undue or unjust inducements.Design, setting, and participantsTwo RCTs of incentives that were embedded in 2 parent RCTs, 1 comparing smoking cessation interventions (conducted at smoking cessation clinics in 2 health systems) and 1 evaluating an ambulation intervention (conducted across wards of the Hospital of the University of Pennsylvania) included all persons eligible for the parent trials who did not have prior knowledge of the incentives trials. Recruitment occurred from September 2017 to August 2019 for the smoking trial and January 2018 through May 2019 for the ambulation trial; data were analyzed from January 2020 to July 2020.InterventionsPatients were randomly assigned to incentives of $0, $200, or $500 for participating in the smoking cessation trial and $0, $100, or $300 for the ambulation trial.Main outcomes and measuresThe primary outcome of each incentive trial was the proportion of people assigned to each recruitment strategy that consented to participate. Each trial was powered to test the hypotheses that incentives served neither as undue inducements (based on the interaction between incentive size and perceived research risk, as measured using a 10-point scale, on the primary outcome), nor unjust inducements (based on the interaction between incentive size and participants' self-reported income). Noninferiority methods were used to test whether the data were compatible with these 2 effects of incentives and superiority methods to compare the primary and other secondary outcomes.ResultsThere were a total of 654 participants (327 women [50.0%]; mean [SD] age, 50.6 [12.1] years; 394 Black/African American [60.2%], 214 White [32.7%], and 24 multiracial individuals [3.7%]) in the smoking trial, and 642 participants (364 women [56.7%]; mean [SD] age, 46.7 [15.6] years; 224 Black/African American [34.9%], 335 White [52.2%], and 5 multiracial individuals [0.8%]) in the ambulation trial. Incentives significantly increased consent rates among those in the smoking trial in 47 of 216 (21.8%), 78 of 217 (35.9%), and 104 of 221 (47.1%) in the $0, $200, and $500 groups, respectively (adjusted odds ratio [aOR] for each increase in incentive, 1.70; 95% CI, 1.34-2.17; P < .001). Incentives did not increase consent among those in the ambulation trial: 98 of 216 (45.4%), 102 of 212 (48.1%), and 92 of 214 (43.0%) in the $0, $100, and $300 groups, respectively (aOR, 0.88; 95% CI, 0.64-1.22; P = .45). In neither trial was there evidence of undue or unjust inducement (upper confidence limits of ORs for undue inducement, 1.15 and 0.99; P < .001 showing noninferiority; upper confidence limits of ORs for unjust inducement, 1.21 and 1.26; P = .01 and P < .001, respectively). There were no significant effects of incentive size on the secondary outcomes in either trial, including time spent reviewing the risk sections of consent forms, perceived research risks, trial understanding, perceived coercion, or therapeutic misconceptions.Conclusions and relevanceIn these 2 randomized clinical trials, financial incentives increased trial enrollment in 1 of 2 trials and did not produce undue or unjust inducement or other unintended consequences in either trial.Trial registrationClinicalTrials.gov Identifier: NCT02697799.

Project description:Migraine is a common neurological disorder which affects 15-20% of the population; it has a high socioeconomic impact through treatment and loss of productivity. Current forms of diagnosis are primarily clinical and can be difficult owing to comorbidity and symptom overlap with other neurological disorders. As such, there is a need for better diagnostic tools in the form of genetic testing. Migraine is a complex disorder, encompassing various subtypes, and has a large genetic component. Genetic studies conducted on rare monogenic subtypes, including familial hemiplegic migraine, have led to insights into its pathogenesis via identification of causal mutations in three genes (CACNA1A, ATP1A2 and SCN1A) that are involved in transport of ions at synapses and glutamatergic transmission. Study of familial migraine with aura pedigrees has also revealed other causal genes for monogenic forms of migraine. With respect to the more common polygenic form of migraine, large genome-wide association studies have increased our understanding of the genes, pathways and mechanisms involved in susceptibility, which are largely involved in neuronal and vascular functions. Given the preponderance of female migraineurs (3:1), there is evidence to suggest that hormonal or X-linked components can also contribute to migraine, and the role of genetic variants in mitochondrial DNA in migraine has been another avenue of exploration. Epigenetic studies of migraine have shown links between hormonal variation and alterations in DNA methylation and gene expression. While there is an abundance of preliminary studies identifying many potentially causative migraine genes and pathways, more comprehensive genomic and functional analysis to better understand mechanisms may aid in better diagnostic and treatment outcomes.

Project description:Genetic mutation of the coproporphyrinogen oxidase (CPOX) gene causes either hereditary coproporphyria (HCP) or harderoporphyria. HCP, a rare hepatic porphyria, causes acute attacks after puberty and rarely accompanies cutaneous symptoms. In contrast, harderoporphyria is an erythropoietic porphyria that represents photosensitivity and hemolytic anemia from the neonatal period. In patients with harderoporphyria, the p.Lys404Glu mutation is found in the homozygous or compound heterozygous state with another mutation, and a marked increase in harderoporphyrin is observed. This report describes a neonate with symptoms of erythropoietic harderoporphyria (photosensitivity of the skin, hemolytic anemia, and jaundice). However, the pattern of porphyrin metabolites of feces was consistent with that of typical HCP, not of harderoporphyria. We found a heterozygous, novel, four-base pair deletion in exon 7 of the CPOX gene, although other mutations including the p.Lys404Glu mutation in CPOX were not found. By unknown etiology, our patient had accompanying adrenocortical insufficiency and 46, XY disorders of sex development. Based on genetic mutation of the CPOX gene and information from a previous similar case report, we consider that neonatal-onset HCP is a variant of HCP.

Project description:BackgroundAntimicrobial resistance (AMR) threatens our ability to treat and prevent infectious diseases worldwide. A significant driver of AMR is antimicrobial use (AMU) in human and veterinary medicine. Therefore, education and awareness of AMR among antimicrobial prescribers is critical. Human and animal health professionals play important roles in the AMR issue, both as contributors to the emergence of AMR, and as potential developers and implementers of effective solutions. Studies have shown that engaging stakeholders prior to developing communication materials can increase relevance, awareness, and dissemination of research findings and communication materials. As future antimicrobial prescribers, medical and veterinary students' perspectives on AMR, as well as their preferences for future communication materials, are important. The first objective of this study was to explore medical and veterinary student perceptions and understanding of factors associated with emergence and spread of AMR. The second objective was to identify key messages, knowledge translation and transfer (KTT) methods, and dissemination strategies for communication of AMR information to these groups.MethodsBeginning in November 2018, focus groups were conducted with medical and veterinary students in Ontario, Canada. A semi-structured format, using standardized open-ended questions and follow-up probing questions was followed. Thematic analysis was used to identify and analyze patterns within the data.ResultsAnalyses showed that students believed AMR to be an important global issue and identified AMU in food-producing animals and human medicine as the main drivers of AMR. Students also highlighted the need to address society's reliance on antimicrobials and the importance of collaboration between different sectors to effectively reduce the emergence and transmission of AMR. When assessing different communication materials, students felt that although infographics provide easily digestible information, other KTT materials such as fact sheets are better at providing more information without overwhelming the target audiences (e.g., professional or general public).ConclusionOverall, the study participants felt that AMR is an important issue and emphasized the need to develop different KTT tools for different audiences. This research will help inform the development of future communication materials, and support development of AMR-KTT tools tailored to the needs of different student and professional groups.

Project description:BACKGROUND:The majority of patients desire all available prognostic information, but some physicians hesitate to discuss prognosis. The objective of the current study was to examine outcomes of prognostic disclosure among the parents of children with cancer. METHODS:The authors surveyed 353 parents of children with newly diagnosed cancer at 2 tertiary cancer centers, and each child's oncologist. Using multivariable logistic regression, the authors assessed associations between parental report of elements of prognosis discussions with the oncologist (quality of information/communication and prognostic disclosure) and potential consequences of these discussions (trust, hope, peace of mind, prognostic understanding, depression, and anxiety). Analyses were stratified by oncologist-reported prognosis. RESULTS:Prognostic disclosure was not found to be associated with increased parental anxiety, depression, or decreased hope. Among the parents of children with less favorable prognoses (<75% chance of cure), the receipt of high-quality information from the oncologist was associated with greater peace of mind (odds ratio [OR], 5.23; 95% confidence interval [95% CI], 1.81-15.16) and communication-related hope (OR, 2.54; 95% CI, 1.00-6.40). High-quality oncologist communication style was associated with greater trust in the physician (OR, 2.45; 95% CI, 1.09-5.48) and hope (OR, 3.01; 95% CI, 1.26-7.19). Accurate prognostic understanding was less common among the parents of children with less favorable prognoses (OR, 0.39; 95% CI, 0.17-0.88). Receipt of high-quality information, high-quality communication, and prognostic disclosure were not found to be significantly associated with more accurate prognostic understanding. CONCLUSIONS:The results of the current study demonstrate no evidence that disclosure is associated with anxiety, depression, or decreased hope. Communication processes may increase peace of mind, trust, and hope. It remains unclear how best to enhance prognostic understanding. Cancer 2018;124:1232-41. © 2017 American Cancer Society.
