Explaining racial/ethnic dietary patter ns in relation to type 2 diabetes: An analysis of NHAN ES 2007-2012
Nowlin, S. Y., Cleland, C. M., Vadiveloo, M., Parekh, N., Melkus, G. D. E., & Hagan, H. (2016). Ethnicity and Disease, 26(4), 529-536. 10.18865/ed.26.4.529
Abstract
Objective: The purpose of this article is to examine sociodemographic and health behavior factors associated with dietary intake as measured by the healthy eating index (HEI-2010) for persons with and without diabetes (T2D). Design: A secondary data analysis of three NHANES data cycles spanning 2007-2012. Multiple linear regression assessed racial/ ethnic differences in HEI-2010 scores in those without T2D, with T2D, and with undiagnosed T2D. Participants: The sample included nonpregnant adults aged ≥20 years who had two days of reliable dietary recall data. Outcome Measures: Total scores for the HEI-2010. Results: For those without T2D, there was a significant association between race/ ethnicity and HEI score, with non-Hispanic Blacks achieving significantly lower scores than their non-Hispanic White counterparts. Differences in HEI-2010 score were also associated with age, sex, smoking status and time spent in the United States. Racial/ ethnic differences in dietary patterns were present, but not significant in those with undiagnosed or diagnosed T2D. Conclusions: Racial/ethnic disparities in dietary patterns are present in individuals without T2D, but differences are not statistically significant in those with undiagnosed or diagnosed T2D. Non-Hispanic Blacks without T2D received significantly lower HEI-2010 scores than non-Hispanic Whites. Further research is necessary to determine whether or not similarities in dietary intake across racial/ethnic groups with T2D will be reflected in diabetes-related health outcomes in this population.
Exploring longitudinal shifts in international nurse migration to the United States between 2003 and 2013 through a random effects panel data analysis
Squires, A., Ojemeni, M. T., & Jones, S. (2016). Human Resources for Health, 14. 10.1186/s12960-016-0118-7
Abstract
Background: No study has examined the longitudinal trends in National Council Licensure Exam for Registered Nurse (NCLEX-RN) applicants and pass rates among internationally-educated nurses (IENs) seeking to work in the United States, nor has any analysis explored the impact of specific events on these trends, including changes to the NCLEX-RN exam, the role of the economic crisis, or the passing of the WHO Code on the International Recruitment of Health Personnel. This study seeks to understand the impact of the three aforementioned factors that may be influencing current and future IEN recruitment patterns in the United States. Methods: In this random effects panel data analysis, we analyzed 11 years (2003-2013) of annual IEN applicant numbers and pass rates for registered nurse credentialing. Data were obtained from publicly available reports on exam pass rates. With the global economic crisis and NCLEX-RN changes in 2008 coupled with the WHO Code passage in 2010, we sought to compare if (1) the number of applicants changed significantly after those 2 years and (2) if pass rates changed following exam modifications implemented in 2008 and 2011. Results: A total of 177 countries were eligible for inclusion in this analysis, representing findings from 200,453 IEN applicants to the United States between 2003 and 2013. The majority of applicants were from the Philippines (58 %) and India (11 %), with these two countries combined representing 69 % of the total. Candidates from Sub-Saharan African countries totalled 7133 (3 % of all applications) over the study period, with half of these coming from Nigeria alone. No significant changes were found in the number of candidates following the 2008 economic crisis or the 2010 WHO Code, although pass rates decreased significantly following the 2008 exam modifications and the WHO Code implementation. Conclusion: This study suggests that, while the WHO Code has had an influence on overall IEN migration dynamics to the United States by decreasing candidate numbers, in most cases, the WHO Code was not the single cause of these fluctuations. Indeed, the impact of the NCLEX-RN exam changes appears to exert a larger influence.
Factors Associated with HPV Vaccination among Cambodian American Teenagers
Lee, H., Kim, M., Kiang, P., Shi, L., Tan, K., Chea, P., Peou, S., & Grigg-Saito, D. C. (2016). Public Health Nursing, 33(6), 493-501. 10.1111/phn.12294
Abstract
Objectives: Parents have general influence over their children's health and health behavior. However, given the dearth of specific literature regarding knowledge level and social and cultural factors influencing HPV vaccination behaviors among Cambodian American (CA) parent, it is difficult to develop an effective, evidence-based public health HPV vaccination program. Therefore, the objectives of this study were to determine the HPV vaccine uptakes among CA teenagers and to examine factors influencing HPV vaccine uptakes. Design and Sample: A descriptive, cross-sectional survey design and a combination of network and targeted sampling methods were used. Results: CA mothers (n = 130) completed a health survey through face-to-face interviews in either English or Khmer language. Girls vaccination rates were 29% while that of boys was 16%. Awareness and knowledge of HPV among CA mothers was very low, and many believed that their daughters, who speak English and were educated in the U.S., had more knowledge about health than they did. Logistic regression analysis showed that CA girls had significantly higher odds of vaccination when their mothers possessed a higher level of English reading ability and had greater awareness and knowledge of HPV. Conclusions: The strikingly low rates of HPV vaccination among CA girls and boys underscore the need to improve vaccination outreach, education, and uptake. The findings can be used to develop targeted public health HPV vaccination programs for CAs, which will reduce cervical cancer disparities.
Factors associated with resident influenza vaccination in a national sample of nursing homes
Travers, J. L., Stone, P. W., Bjarnadottir, R. I., Pogorzelska-Maziarz, M., Castle, N. G., & Herzig, C. T. (2016). American Journal of Infection Control, 44(9), 1055-1057. 10.1016/j.ajic.2016.01.019
Abstract
Influenza vaccination remains the cornerstone of influenza prevention, yet national goals for nursing home residents and staff vaccination have not been met. Few studies have examined associations between facility and resident characteristics; employee processes, such as staff vaccination policies; and resident influenza vaccination. In this national survey of nursing homes, employee processes were not associated with resident influenza vaccination; however, various facility and resident characteristics were.
Family caregivers of patients with frontotemporal dementia: An integrative review
Caceres, B. A., Frank, M. O., Jun, J., Martelly, M. T., Sadarangani, T., & De Sales, P. C. (2016). International Journal of Nursing Studies, 55, 71-84. 10.1016/j.ijnurstu.2015.10.016
Abstract
Objectives: The purpose of this integrative review is to: (1) identify the characteristics of family caregivers of patients with frontotemporal dementia, (2) explore the impact of providing care on family caregivers' health and well-being, and (3) identify coping strategies used by family caregivers. Background: Frontotemporal dementia is thought to be the second most common form of dementia after Alzheimer's disease. Family caregivers of patients with frontotemporal dementia face unique challenges due to its early onset, behavioral symptoms, and slow progression of decline. However, there is a dearth of research evaluating the health and wellbeing of family caregivers of patients with frontotemporal dementia. Design and data sources: An integrative review was conducted using the Whittemore and Knafl methodology. An electronic search of the literature was conducted using four electronic databases: PubMed, Embase, CINAHL, and Web of Science. The Crowe Critical Appraisal tool was used to evaluate the quality of the selected articles. Results: Findings of 11 articles informed this integrative review. Family caregivers of patients with frontotemporal dementia identify behavioral disturbances as most troubling. Spouses and female caregivers experience greater caregiver burden, distress, increased rates of depression, as well as decreased sleep related to behavior disturbances. Though less explored, providing care to those with behavioral disturbances may also impact caregiver physical health. Additionally, female caregivers are most likely to employ coping strategies, most commonly, adaptation and reframing. Effective interventions to reduce family caregiver burden are poorly understood but family caregivers suggest education and internet-based support groups are most helpful. Conclusions: Family caregivers of patients with frontotemporal dementia experience significant distress, which impacts their health and wellbeing. It is important for healthcare providers who care for patients with frontotemporal dementia to recognize the unique needs of family caregivers. Future research should focus on examining interventions and strategies to reduce caregiver burden.
Feasibility and acceptability of an audio computer-assisted self-interview version of the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) in primary care patients
Spear, S. E., Shedlin, M., Gilberti, B., Fiellin, M., & McNeely, J. (2016). Substance Abuse, 37(2), 299-305. 10.1080/08897077.2015.1062460
Abstract
Background: This study explores the feasibility and acceptability of a computer self-administered approach to substance use screening from the perspective of primary care patients. Methods: Forty-eight patients from a large safety net hospital in New York City completed an audio computer-assisted self-interview (ACASI) version of the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) and a qualitative interview to assess feasibility and acceptability, comprehension, comfort with screening questions, and preferences for screening mode (interviewer or computer). Qualitative data analysis organized the participants' feedback into major themes. Results: Participants overwhelmingly reported being comfortable with the ACASI ASSIST. Mean administration time was 5.2 minutes (range: 1.6–14.8 minutes). The major themes from the qualitative interviews were (1) ACASI ASSIST is feasible and acceptable to patients, (2) Social stigma around substance use is a barrier to patient disclosure, and (3) ACASI screening should not preclude personal interaction with providers. Conclusions: The ACASI ASSIST is an appropriate and feasible approach to substance use screening in primary care. Because of the highly sensitive nature of substance use, screening tools must explain the purpose of screening, assure patients that their privacy is protected, and inform patients of the opportunity to discuss their screening results with their provider.
Feeling Heard and Understood: A Patient-Reported Quality Measure for the Inpatient Palliative Care Setting
Gramling, R., Stanek, S., Ladwig, S., Gajary-Coots, E., Cimino, J., Anderson, W., Norton, S. A., Aslakson, R. A., Ast, K., Elk, R., Garner, K. K., Grudzen, C., Kamal, A. H., Lamba, S., Leblanc, T. W., Rhodes, R. L., Roeland, E., Schulman-Green, D., & Unroe, K. T. (2016). Journal of Pain and Symptom Management, 51(2), 150-154. 10.1016/j.jpainsymman.2015.10.018
Abstract
Context As endorsed by the palliative care "Measuring What Matters" initiative, capturing patients' direct assessment of their care is essential for ongoing quality reporting and improvement. Fostering an environment where seriously ill patients feel heard and understood is of crucial importance to modern health care. Objectives To describe the development and performance of a self-report field measure for seriously ill patients to report how well they feel heard and understood in the hospital environment. Methods As part of a larger ongoing cohort study of inpatient palliative care, we developed and administered the following point-of-care item: "Over the past two days, how much have you felt heard and understood by the doctors, nurses and hospital staff?" (completely, quite a bit, moderately, slightly, not at all). Participants completed the measure before and the day after palliative care consultation. For the postconsultation version, we changed the time frame from "past two days" to "today." Results One hundred sixty patients with advanced cancer completed the preconsultation assessment, and 87% of them completed the postconsultation version. Responses encompassed full use of the ordinal scale, did not exhibit ceiling or floor effects, and showed improvement from preassessment to postassessment. The item was quick to administer and easy for patients to complete. Conclusion The "Heard & Understood" item is a promising self-report quality measure for the inpatient palliative care setting.

First trimester pregnancy-associated plasma protein-A and birth weight
Baer, R. J., Lyell, D. J., Norton, M. E., Currier, R. J., & Jelliffe-Pawlowski, L. L. (2016). European Journal of Obstetrics and Gynecology and Reproductive Biology, 198, 1-6. 10.1016/j.ejogrb.2015.12.019
Abstract
Objective To evaluate first trimester pregnancy-associated plasma protein-A (PAPP-A) and birth weight percentile. Study design Included were women who underwent first trimester prenatal screening through the California Prenatal Screening Program with expected dates of delivery between August 2009 and December 2010, linked birth certificate and hospital discharge records, known birth weight, and no chromosomal abnormality (n = 134.105). PAPP-A results were reported as multiples of the median. The frequency of small or large for gestational age (SGA, ≤10%; LGA, ≥90%) versus appropriately grown for gestational age birth was examined by PAPP-A percentile. Patterns were studied by gestational age at delivery. Relative risks (RRs) and their 95% confidence intervals were adjusted for race/ethnicity. Results Women with PAPP-A ≤10th percentile and an infant born after 32 weeks were increasingly more likely to have an SGA infant ( adj RRs 1.5-4.6) as the PAPP-A percentile declined, and were increasingly less like to have an LGA infant born at term ( adj RRs 0.5-0.7) compared to women with PAPP-A measurement >10th to <90th percentile. PAPP-A ≥90th percentile was protective for SGA among infants born after 32 weeks gestation ( adj RRs 0.3-0.7) and was associated with LGA among infants born at term ( adj RRs 1.2-8.2). Conclusion Women with PAPP-A ≤10th percentile are more likely to have an SGA infant at all gestational ages. PAPP-A ≥90th percentile is protective against SGA and is associated with an increased risk of LGA for infants born after 32 weeks gestation.
From the closest observers of patient care: A thematic analysis of online narrative reviews of hospitals
Bardach, N. S., Lyndon, A., Asteria-Peñaloza, R., Goldman, L. E., Lin, G. A., & Dudley, R. A. (2016). BMJ Quality and Safety, 25(11), 889-897. 10.1136/bmjqs-2015-004515
Abstract
Objective: Patient-centred care has become a priority in many countries. It is unknown whether current tools capture aspects of care patients and their surrogates consider important. We investigated whether online narrative reviews from patients and surrogates reflect domains in the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) and we described additional potential domains. Design: We used thematic analysis to assess online narrative reviews for reference to HCAHPS domains and salient non-HCAHPS domains and compared results by reviewer type (patient vs surrogate). Setting: We identified hospitals for review from the American Hospital Association database using a stratified random sampling approach. This approach ensured inclusion of reviews of a diverse set of hospitals. We searched online in February 2013 for narrative reviews from any source for each hospital. Participants: We included up to two narrative reviews for each hospital. Exclusions: Outpatient or emergency department reviews, reviews from self-identified hospital employees, or reviews of <10 words. Results: 50.0% (n=122) of reviews (N=244) were from patients and 38.1% (n=93) from friends or family members. Only 57.0% (n=139) of reviews mentioned any HCAHPS domain. Additional salient domains were: Financing, including unexpected out-of-pocket costs and difficult interactions with billing departments; system-centred care; and perceptions of safety. These domains were mentioned in 51.2% (n=125) of reviews. Friends and family members commented on perceptions of safety more frequently than patients. Conclusions: A substantial proportion of consumer reviews do not mention HCAHPS domains. Surrogates appear to observe care differently than patients, particularly around safety.
Gene Expression Profiling of Evening Fatigue in Women Undergoing Chemotherapy for Breast Cancer
Kober, K. M., Dunn, L., Mastick, J., Cooper, B., Langford, D., Melisko, M., Venook, A., Chen, L. M., Wright, F., Hammer, M., Schmidt, B. L., Levine, J., Miaskowski, C., & Aouizerat, B. E. (2016). Biological Research for Nursing, 18(4), 370-385. 10.1177/1099800416629209
Abstract
Moderate-to-severe fatigue occurs in up to 94% of oncology patients undergoing active treatment. Current interventions for fatigue are not efficacious. A major impediment to the development of effective treatments is a lack of understanding of the fundamental mechanisms underlying fatigue. In the current study, differences in phenotypic characteristics and gene expression profiles were evaluated in a sample of breast cancer patients undergoing chemotherapy (CTX) who reported low (n = 19) and high (n = 25) levels of evening fatigue. Compared to the low group, patients in the high evening fatigue group reported lower functional status scores, higher comorbidity scores, and fewer prior cancer treatments. One gene was identified as upregulated and 11 as downregulated in the high evening fatigue group. Gene set analysis found 24 downregulated and 94 simultaneously up- and downregulated pathways between the two fatigue groups. Transcript origin analysis found that differential expression (DE) originated primarily from monocytes and dendritic cell types. Query of public data sources found 18 gene expression experiments with similar DE profiles. Our analyses revealed that inflammation, neurotransmitter regulation, and energy metabolism are likely mechanisms associated with evening fatigue severity; that CTX may contribute to fatigue seen in oncology patients; and that the patterns of gene expression may be shared with other models of fatigue (e.g., physical exercise and pathogen-induced sickness behavior). These results suggest that the mechanisms that underlie fatigue in oncology patients are multifactorial.
Gestational dating by metabolic profile at birth: A California cohort study
Jelliffe-Pawlowski, L. L., Norton, M. E., Baer, R. J., Santos, N., & Rutherford, G. W. (2016). American Journal of Obstetrics and Gynecology, 214(4), 511.e1-511.e13. 10.1016/j.ajog.2015.11.029
Abstract
Background Accurate gestational dating is a critical component of obstetric and newborn care. In the absence of early ultrasound, many clinicians rely on less accurate measures, such as last menstrual period or symphysis-fundal height during pregnancy, or Dubowitz scoring or the Ballard (or New Ballard) method at birth. These measures often underestimate or overestimate gestational age and can lead to misclassification of babies as born preterm, which has both short- and long-term clinical care and public health implications. Objective We sought to evaluate whether metabolic markers in newborns measured as part of routine screening for treatable inborn errors of metabolism can be used to develop a population-level metabolic gestational dating algorithm that is robust despite intrauterine growth restriction and can be used when fetal ultrasound dating is not available. We focused specifically on the ability of these markers to differentiate preterm births (PTBs) (<37 weeks) from term births and to assign a specific gestational age in the PTB group. Study Design We evaluated a cohort of 729,503 singleton newborns with a California birth in 2005 through 2011 who had routine newborn metabolic screening and fetal ultrasound dating at 11-20 weeks' gestation. Using training and testing subsets (divided in a ratio of 3:1) we evaluated the association among PTB, target newborn characteristics, acylcarnitines, amino acids, thyroid-stimulating hormone, 17-hydroxyprogesterone, and galactose-1-phosphate-uridyl-transferase. We used multivariate backward stepwise regression to test for associations and linear discriminate analyses to create a linear function for PTB and to assign a specific week of gestation. We used sensitivity, specificity, and positive predictive value to evaluate the performance of linear functions. Results Along with birthweight and infant age at test, we included 35 of the 51 metabolic markers measured in the final multivariate model comparing PTBs and term births. Using a linear discriminate analyses-derived linear function, we were able to sort PTBs and term births accurately with sensitivities and specificities of ≥95% in both the training and testing subsets. Assignment of a specific week of gestation in those identified as PTBs resulted in the correct assignment of week ±2 weeks in 89.8% of all newborns in the training and 91.7% of those in the testing subset. When PTB rates were modeled using the metabolic dating algorithm compared to fetal ultrasound, PTB rates were 7.15% vs 6.11% in the training subset and 7.31% vs 6.25% in the testing subset. Conclusion When considered in combination with birthweight and hours of age at test, metabolic profile evaluated within 8 days of birth appears to be a useful measure of PTB and, among those born preterm, of specific week of gestation ±2 weeks. Dating by metabolic profile may be useful in instances where there is no fetal ultrasound due to lack of availability or late entry into care.

Hartford Gerontological Nursing Leaders: From Funding Initiative to National Organization
Failed generating bibliography.
Abstract
Abstract
In 2000, the John A. Hartford Foundation established the Building Academic Geriatric Nursing Capacity Program initiative, acknowledging nursing's key role in the care of the growing population of older adults. This program has supported 249 nurse scientists with pre- and postdoctoral awards. As a result of the program's success, several Building Academic Geriatric Nursing Capacity Program awardees formed an alumni organization to continue to advance the quality care of older adults. This group of Building Academic Geriatric Nursing Capacity Program awardees joined others receiving support from the John A. Hartford Foundation nursing initiatives to grow a formal organization, the Hartford Gerontological Nursing Leaders (HGNL). The purpose of this article is to present the development, accomplishments, and challenges of the HGNL, informing other professional nursing organizations that are experiencing similar accomplishments and challenges. This article also demonstrates the power of a funding initiative to grow an organization dedicated to impact gerontological health and health care through research, practice, education, and policy.

High Prevalence of Medication Discrepancies Between Home Health Referrals and Centers for Medicare and Medicaid Services Home Health Certification and Plan of Care and Their Potential to Affect Safety of Vulnerable Elderly Adults
Brody, A. A., Gibson, B., Tresner-Kirsch, D., Kramer, H., Thraen, I., Coarr, M. E., & Rupper, R. (2016). Journal of the American Geriatrics Society, 64(11), e166-e170. 10.1111/jgs.14457
Abstract
Objectives: To describe the prevalence of discrepancies between medication lists that referring providers and home healthcare (HH) nurses create. Design: The active medication list from the hospital at time of HH initiation was compared with the HH agency's plan of care medication list. An electronic algorithm was developed to compare the two lists for discrepancies. Setting: Single large hospital and HH agency in the western United States. Participants: Individuals referred for HH from the hospital in 2012 (N = 770, 96.3% male, median age 71). Measurements: Prevalence was calculated for discrepancies, including medications missing from one list or the other and differences in dose, frequency, or route for medications contained on both lists. Results: Participants had multiple medical problems (median 16 active problems) and were taking a median of 15 medications (range 1–93). Every participant had at least one discrepancy; 90.1% of HH lists were missing at least one medication that the referring provider had prescribed, 92.1% of HH lists contained medications not on the referring provider's list, 89.8% contained medication naming errors. 71.0% contained dosing discrepancies, and 76.3% contained frequency discrepancies. Conclusion: Discrepancies between HH and referring provider lists are common. Future work is needed to address possible safety and care coordination implications of discrepancies in this highly complex population.

Hospitals Known for Nursing Excellence Associated with Better Hospital Experience for Patients
Stimpfel, A. W., Sloane, D. M., McHugh, M. D., & Aiken, L. H. (2016). Health Services Research, 51(3), 1120-1134. 10.1111/1475-6773.12357
Abstract
Objective To examine the relationship between Magnet recognition, an indicator of nursing excellence, and patients' experience with their hospitalization reported in the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey. Data Sources This secondary analysis includes cross-sectional data from the 2010 HCAHPS survey, the American Hospital Association, and the American Nurses Credentialing Center. Study Design We conducted a retrospective observational study. Data Collection Using common hospital identifiers, we created a matched set of 212 Magnet hospitals and 212 non-Magnet hospitals. Principal Findings Patients in Magnet hospitals gave their hospitals higher overall ratings, were more likely to recommend their hospital, and reported more positive care experiences with nurse communication. Conclusions Magnet recognition is associated with better patient care experiences, which may positively enhance reimbursement for hospitals.
How Factor Analysis Results May Change Due to Country Context
Brzyski, P., Kózka, M., Squires, A., & Brzostek, T. (2016). Journal of Nursing Scholarship, 48(6), 598-607. 10.1111/jnu.12249
Abstract
Purpose: To present how factor analysis results of a Practice Environment Scale of the Nursing Work Index (PES-NWI) translation changed due to country context. Design: Validity and reliability analysis of a cross-culturally adapted, Polish translation of the PES-NWI came from a cross-sectional, national survey that included 2,605 registered nurses working in surgical (50.4%) and medical (49.6%) units of 30 Polish hospitals. Methods: Exploratory factor analysis (EFA) using the principal component analysis (PCA) method with varimax rotation and confirmatory factor analysis (CFA) was used to examine factor structure of the instrument in the Polish context. Zero-order and partial Pearson correlation coefficients were used to establish the range of variance shared by the dimensions of the Polish version. The Cronbach's alpha coefficient determined internal consistency reliability. The internal consistency of the scale was also tested based on Kline's criterion. Findings: The PCA conducted in the sample of Polish nurses extracted six factors, explaining together 56% of the total variance. The varimax rotation, however, restricted results to five factors, explaining 52.7% of the total variance and generating a factor structure closer to that based on previous studies. The CFA model, based on a PCA solution with five nonorthogonal factors, fitted data better than the theoretically driven model. Conclusions: Dimensions of the PES-NWI nurses’ work environments remain conceptually consistent in Poland, but load differently. Health system or nursing profession factors related to the country context are potential explanations for these differences. Clinical Relevance: When using a translation of the Practice Environment Scale of the Nursing Work Index-Revised to examine the influences of work environment quality on nursing and patient outcomes, it is important to consider contextual differences when using results to inform policy.
Human leucocyte antigen class I and II imputation in a multiracial population
Kuniholm, M. H., Xie, X., Anastos, K., Xue, X., Reimers, L., French, A. L., Gange, S. J., Kassaye, S. G., Kovacs, A., Wang, T., Aouizerat, B. E., & Strickler, H. D. (2016). International Journal of Immunogenetics, 43(6), 369-375. 10.1111/iji.12292
Abstract
Human leucocyte antigen (HLA) genes play a central role in response to pathogens and in autoimmunity. Research to understand the effects of HLA genes on health has been limited because HLA genotyping protocols are labour intensive and expensive. Recently, algorithms to impute HLA genotype data using genome-wide association study (GWAS) data have been published. However, imputation accuracy for most of these algorithms was based primarily on training data sets of European ancestry individuals. We considered performance of two HLA-dedicated imputation algorithms – SNP2HLA and HIBAG – in a multiracial population of n = 1587 women with HLA genotyping data by gold standard methods. We first compared accuracy – defined as the percentage of correctly predicted alleles – of HLA-B and HLA-C imputation using SNP2HLA and HIBAG using a breakdown of the data set into an 80% training group and a 20% testing group. Estimates of accuracy for HIBAG were either the same or better than those for SNP2HLA. We then conducted a more thorough test of HIBAG imputation accuracy using five independent 10-fold cross-validation procedures with delineation of ancestry groups using ancestry informative markers. Overall accuracy for HIBAG was 89%. Accuracy by HLA gene was 93% for HLA-A, 84% for HLA-B, 94% for HLA-C, 83% for HLA-DQA1, 91% for HLA-DQB1 and 88% for HLA-DRB1. Accuracy was highest in the African ancestry group (the largest group) and lowest in the Hispanic group (the smallest group). Despite suboptimal imputation accuracy for some HLA gene/ancestry group combinations, the HIBAG algorithm has the advantage of providing posterior estimates of accuracy which enable the investigator to analyse subsets of the population with high predicted (e.g. >95%) imputation accuracy.
I disegni di ricerca con metodo misto: Un approccio metodologico innovative per la ricerca infermieristica
Paturzo, M., Colaceci, S., Clari, M., Mottola, A., Alvaro, R., Dickson, V. V., & Vellone, E. (2016). Assistenza Infermieristica E Ricerca, 35(2), 82-86. 10.1702/2310.24838
Abstract
The mixed method research designs (MM) combine qualitative and quantitative approaches in the research process, in a single study or series of studies. Their use can provide a wider understanding of multifaceted phenomena. This article presents a general overview of the structure and design of MM to spread this approach in the Italian nursing research community. The MM designs most commonly used in the nursing field are the convergent parallel design, the sequential explanatory design, the exploratory sequential design and the embedded design. For each method a research example is presented. The use of MM can be an added value to improve clinical practices as, through the integration of qualitative and quantitative methods, researchers can better assess complex phenomena typical of nursing.
