Abstract

Introduction The objective of this study was to assess dental service utilization across different Asian immigrant groups and to examine the relationship between acculturation and dental service utilization among Asian immigrants in the U.S. Methods Data were from the 2013 and 2014 National Health Interview Surveys. Multiple logistic regression models were used to examine the association between acculturation and having a dental visit in the previous 12 months, controlling for predisposing, enabling, and need factors. Acculturation was measured by length of stay in the U.S., English language proficiency, and U.S. citizenship. The sample was 2,948 adult Asian immigrants who were dentate. Data were analyzed in 2016. Results Dental service utilization varied across Asian immigrant groups. High English proficiency and longer length of stay were significantly associated with having a dental visit (p<0.05). In the final model, after adding enabling factors—dental insurance and family income levels—length of stay in the U.S. (≥5 years) remained significant, whereas English language proficiency was not a significant correlate of having a dental visit. Conclusions Length of stay in the U.S. is a significant factor affecting dental service utilization among Asian immigrants.

Abstract

We evaluated performance, accuracy, and acceptability parameters of unsupervised oral fluid (OF) HIV self-testing (HIVST) in a general population in western Kenya. In a prospective validation design, we enrolled 240 adults to perform rapid OF HIVST and compared results to staff administered OF and rapid fingerstick tests. All reactive, discrepant, and a proportion of negative results were confirmed with lab ELISA. Twenty participants were video-recorded conducting self-testing. All participants completed a staff administered survey before and after HIVST to assess attitudes towards OF HIVST acceptability. HIV prevalence was 14.6 %. Thirty-six of the 239 HIVSTs were invalid (15.1 %; 95 % CI 11.1–20.1 %), with males twice as likely to have invalid results as females. HIVST sensitivity was 89.7 % (95 % CI 73–98 %) and specificity was 98 % (95 % CI 89–99 %). Although sensitivity was somewhat lower than expected, there is clear interest in, and high acceptability (94 %) of OF HIV self-testing.

Abstract

Background Accuracy of body weight perception is an individual's perception of their body weight in comparison with actual body weight and is associated with weight-related behaviors. Chinese Americans have increased risk for obesity but no studies have examined accuracy of body weight perception. Methods This study was a descriptive and cross-sectional study, which was conducted in a community health center in New York. Study subjects were all Chinese-American adults. Demographic information, accuracy of perception of body weight, anthropometric measures (weight, height, body mass index [BMI], waist circumference [WC], hip circumference [HC], weight to height ratio, weight to hip ratio), fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1C) and obesity-related diseases (hypertension, diabetes, heart disease, and stroke) were assessed. Results A total of 162 Chinese Americans were recruited. 52 subjects (32%) did not perceive body weight correctly: 32 subjects had underestimation and 20 subjects had overestimation of body weight. Significant differences were found among subjects in the three groups of different accuracy of body weight perception in terms of gender (p = 0.003), age (p = 0.003), education years (p = 0.047), WC (p < 0.001), HC (p ≤ 0.001), weight/height ratio (p = 0.001), and BMI (p < 0.001). Accuracy of perception of body weight significantly predicted WC (p < 0.001), HC (p < 0.001), weight to height ratio (p = 0.001), BMI (p < 0.001) and weight (< 0.001) even after controlling for all demographic factors. Discussion and conclusion The study identified that around one-third of Chinese Americans did not perceive their body weight correctly. Intervention studies for obesity management in Chinese Americans should address gender difference, target on older subjects, and focus on educating the normal values and significances of WC, HC and HbA1C among Chinese Americans.

Abstract

Background An Audio Computer-assisted Self Interview (ACASI) version of the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) could reduce barriers to substance use screening and assessment in primary care settings. This study evaluated the diagnostic accuracy of an ACASI ASSIST for identification of unhealthy substance use and substance use disorders (SUD). Methods 399 adult patients were consecutively recruited from an urban safety-net primary care clinic. ACASI ASSIST scores for tobacco, alcohol, marijuana, and cocaine were compared against reference standard measures to assess the instrument's diagnostic accuracy for identifying unhealthy use and SUD, first using empirically-derived optimal cutoffs, and second using the currently recommended ASSIST cutoffs. Results For identifying any unhealthy use, at the empirically-derived cutoffs the ACASI ASSIST had 93.6% sensitivity and 85.8% specificity (AUC = 0.90) for tobacco, 85.9% sensitivity and 60.3% specificity (AUC = 0.73), for alcohol in men, 100% sensitivity and 62.4% specificity (AUC = 0.81) for alcohol in women, 94.6% sensitivity and 81.6% specificity (AUC = 0.88) for marijuana, and 86.1% sensitivity, 84.0% specificity (AUC = 0.85) for cocaine. For SUD, sensitivity ranged from 79% (for alcohol in males), to 100% (for tobacco), and specificity was 83% or higher (AUCs ranged 0.83–0.91). For substances other than tobacco, empirically-derived cutoff scores were lower than the standard cutoffs, and resulted in higher sensitivity and lower specificity for identifying unhealthy substance use. Conclusions The ACASI ASSIST is a valid measure of unhealthy use and SUD for substances that are commonly used by primary care patients, and could facilitate effective and efficient screening for substance use in medical settings.

Abstract

Objectives: To examine innovative models and other research-based interventions that hold potential to assure high-quality care for the growing older adult population living with cancer as one of multiple chronic conditions. Evidence from these care delivery approaches provides a roadmap for the development of future care models. Data Sources: Published peer-reviewed literature, policy analyses, and web-based resources. Conclusion: Available evidence suggests the need for models that engage patients and their family caregivers, focus on patient's functional capacities, emphasize palliative care, and maximize the contributions of all team members. Implications for Nursing Practice: Nurses are uniquely positioned to lead or play a major role in the evolution and implementation of care models targeting older adults with cancer, but must increase their knowledge and skills related to both oncology and geriatrics to maximize their contributions.

Abstract

Background: Obesity disproportionately affects Latina women, but few targeted, technology-assisted interventions that incorporate tailored health information exist for this population. The Veterans Health Administration (VHA) uses an online weight management tool (MOVE!23) which is publicly available, but was not designed for use in non-VHA populations. Methods: We conducted a qualitative study to determine how interactions between the tool and other contextual elements impacted task performance when the target Latina users interacted with MOVE!23. We sought to identify and classify specific facilitators and barriers that might inform design changes to the tool and its context of use, and in turn promote usability. Six English-speaking, adult Latinas were recruited from an inner city primary care clinic and a nursing program at a local university in the United States to engage in a “Think-Aloud” protocol while using MOVE!23. Sessions were recorded, transcribed, and coded to identify interactions between four factors that contribute to usability (Tool, Task, User, Context). Results: Five themes influencing usability were identified: Technical Ability and Technology Preferences; Language Confusion and Ambiguity; Supportive Tool Design and Facilitator Guidance; Relevant Examples; and Personal Experience. Features of the tool, task, and other contextual factors failed to fully support participants at times, impeding task completion. Participants interacted with the tool more readily when its language was familiar and content was personally relevant. When faced with ambiguity and uncertainty, they relied on the tool’s visual cues and examples, actively sought relevant personal experiences, and/or requested facilitator support. Conclusions: The ability of our participants to successfully use the tool was influenced by the interaction of individual characteristics with those of the tool and other contextual factors. We identified both tool-specific and context-related changes that could overcome barriers to the use of MOVE!23 among Latinas. Several general considerations for the design of eHealth tools are noted.

Abstract

Patients with irritable bowel syndrome (IBS) have often associated the worsening of symptoms with specific foods. Research is starting to catch up with what patients have reported about food interaction and their symptoms, and the role of diet is being increasingly recognized for the management of IBS. Clinical guidance for nurse practitioners can be challenging because of limited data and guideline consensus along with the nuances of symptoms associated with IBS subtypes. This article summarizes some of the key themes and dietary recommendations by various gastrointestinal organizations, public health agencies, and dietary associations. By addressing the relevance of diet for symptom alleviation, nurse practitioners are able to better support patients and collaborate with dietitians to improve symptom management.

Abstract

Context Measuring What Matters (MWM) prioritizes quality measures in palliative care practice. Hematologic malignancy patients are less likely to access palliative care, yet little is known about their unique needs. Differences in MWM adherence may highlight opportunities to improve palliative care in hematology. Objectives To assess adherence to MWM measures by palliative care clinicians caring for patients with hematologic malignancies, compared to those with solid tumors. Methods We used the Quality Data Collection Tool to assess completion of MWM measures across nine sites. Results We included data from 678 patients' first visits and various care settings; 64 (9.4%) had a hematologic malignancy, whereas 614 (90.6%) had a solid tumor. Hematology patients were more likely to be seen in a hospital (52 or 81.3% vs. 420 or 68%), whereas solid tumor patients were more frequently seen at home or in clinics (160 or 26% vs. 7 or 10.9%). Of the nine MWM measures we assessed, high adherence (>90%) was seen regardless of tumor type in measures #3 (Pain Treatment), #7 (Spiritual Concerns), #8 (Treatment Preferences), and #9 (Care Consistent With Preferences). Clinicians seeing hematology patients were significantly less likely to meet measures #2 (Screening for Physical Symptoms; 57.8% vs. 84.2%, P < 0.001), and #5 (Discussion of Emotional Needs; 56.3% vs. 70.0%, P = 0.03). Conclusion MWM adherence regarding symptom assessment and meeting emotional needs was lower for patients with hematologic malignancies compared to those with solid tumors. This finding suggests two key areas for quality improvement initiatives in palliative care for patients with hematologic malignancies.

Abstract

Background Few studies have employed standardized alcohol misuse measures to assess relationships with sexual risk and HIV/syphilis infections among Chinese men who have sex with men (MSM). Methods We conducted a cross-sectional study among MSM in Beijing during 2013–2014. An interviewer-administered survey was conducted to collect data on sociodemographics, high-risk behaviors, and alcohol use/misuse patterns (hazardous/binge drinking and risk of alcohol dependence) in the past 3 months using Alcohol Use Disorder Identification Test-Consumption (AUDIT-C). We defined AUDIT-C score ≥4 as recent hazardous drinkers, and drinking ≥6 standard drinks on one occasion as recent binge drinkers. Results Of 3588 participants, 14.4% reported hazardous drinking, 16.8% reported binge drinking. Hazardous and binge drinking are both associated with these factors (p < 0.05): older age, being migrants, living longer in Beijing, township/village origin, being employed, higher income, self-perceived low/no HIV risk, and sex-finding via non-Internet venues. Hazardous (vs non-hazardous) or binge (vs. non-binge) drinkers were more likely to use illicit drugs, use alcohol before sex, have multiple partnerships, pay for sex, and have condomless insertive anal intercourse. MSM who reported binge (AOR, 1.34, 95% CI, 1.02–1.77) or hazardous (AOR, 1.36, 95% CI, 1.02–1.82) drinking were more likely to be HIV-infected. MSM at high risk of current alcohol dependence (AUDIT-C ≥8) were more likely to be HIV- (AOR, 2.37, 95% CI, 1.39–4.04) or syphilis-infected (AOR, 1.96, 95% CI, 1.01–3.86). Conclusions Recent alcohol misuse was associated with increased sexual and HIV/syphilis risks among Chinese MSM, emphasizing the needs of implementing alcohol risk reduction programs in this population.

Abstract

During pregnancy, maternal serum alpha-fetoprotein (MSAFP) is commonly used as a second trimester prenatal screening biomarker for chromosomal and structural birth defects. In the absence of birth defects, abnormal levels of mid-pregnancy MSAFP are associated with adverse pregnancy outcomes including fetal demise and preterm birth. Pregnancies ending in fetal demise or preterm birth often have unusually lower or higher mid-pregnancy MSAFP levels than pregnancies that do not. The same is true for pregnancies with specific conditions that are closely related to fetal demise and preterm birth including preeclampsia, conditions of abnormal placentation (e.g., previa, abruption, accreta), and pregnancies carrying a fetus with intrauterine growth restriction. In this chapter, we review specific studies looking at the relationship between MSAFP and fetal demise or preterm birth. In addition, we will review associations between MSAFP and conditions with close links to fetal demise and preterm birth including preeclampsia, placenta previa, placental abruption, placenta accreta, and intrauterine growth restriction. We also provide a brief review of the pathophysiological literature that underscores these relationships and we suggest next steps with respect to research and clinical use of MSAFP data.

Abstract

Purpose: The primary aimof this study was to assess the feasibility of an exercise counseling intervention for adults of diverse race/ ethnicity with heart failure (HF) and to assess its potential for improving overall physical activity, functional capacity, and HF self-care. Design: This study was a quasi-experimental, prospective, longitudinal cohort design. Methods: Twenty adults were enrolled and completed the 6-minute walk and standardized instruments, followed by exercise counseling using motivational interviewing. Each received an accelerometer, hand weights, and a diary to record self-care behaviors. Participants were followed via phone for 12 weeks to collect step-counts, review symptoms, and plan the following week's step goal. Findings: Results indicate that this interventionwas feasible formost participants and resulted in improvements in physical activity, functional capacity, and self-care behaviors. Conclusion/Clinical Relevance: Brief exercise counseling may be an appropriate option to improve outcomes for stable patients with HF and may be tailored to fit different settings.

Abstract

Background: Schools are a key setting for childhood obesity interventions, yet nurses are not often included in delivering these interventions. The objective of this systematic review and meta-analysis was to examine school-based interventions involving nurses in a role beyond anthropometric measurement for effect on change in body measures. Methods: We performed a systematic review and meta-analysis of these papers. Results: The literature search produced 2412 articles. Eleven met inclusion criteria for the systematic review (4 randomized controlled trail [RCT], 7 quasi-experimental) and 8 for the meta-analysis. None have been included in prior meta-analyses. Four studies restricted eligibility to overweight and/or obese children; 7 included all children regardless of body weight. Random effects meta-analytic models represent data from 6050 (body mass index [BMI]), 5863 (BMIz), and 416 (BMI percentile) children, respectively. Pooled analyses demonstrated statistically significant decreases in BMI (6 studies: -0.48 [95% CI -0.84, -0.12]; I2=91.2%, Q=68.1), BMIz (5 studies: -0.10 [95% CI: -0.15, -0.05]; I2=0, Q=2.3), and BMI percentile (3 studies: -0.41 [95% CI: -0.60, -0.21]; I2=0, Q=2.0). Conclusions: These findings are similar to those of other meta-analyses of school-based interventions and suggest that school nurses can play a key role in implementing sustainable, effective school-based obesity interventions.

Abstract

Context Documentation of the emotional or psychological needs of seriously ill patients receiving specialty palliative care is endorsed by the “Measuring What Matters” project as a quality performance metric and recommended for use by hospice and palliative care programs for program improvement. Objectives The aim of this study was to increase the proportion of inpatient palliative care team encounters in which emotional or psychological needs of patients and family members were documented and to qualitatively enrich the nature of this documentation. Methods This is a mixed-methods retrospective study of 200 patient charts reviewed before and after implementation of a structured note template (SmartPhrase) for palliative care encounters. Patterns of documentation of emotional needs pre- and post-implementation were assessed quantitatively and qualitatively using thematic analysis. Results A total of 158 of 200 pre-intervention charts and 185 of 200 post-intervention charts included at least one note from the palliative care team. Documentation of emotional assessment increased after SmartPhrase implementation (63.9% [101 of 158] vs. 74.6% [138 of 185]; P < 0.03). Qualitative analysis revealed a post-intervention reduction in the use of generic phrases (“emotional support provided”) and an increase in the breadth and depth of emotion-related documentation. Conclusion A structured note template with a prompt for emotional assessment increases the overall quantity and richness of documentation related to patient and family emotions. However, this documentation remains mostly descriptive. Additional prompting for documentation of recommendations to address identified emotional needs, and the use of screening tools for depression and anxiety, when appropriate, may be necessary for clinically meaningful quality improvements in patient care.

Abstract

Recent medical advances have resulted in increased survival of children with complex medical conditions (CMC), but there are no validated methods to measure their care needs. Objectives/methods: To design and test the Nursing-Kids Intensity of Care Survey (N-KICS) tool and describe intensity of nursing care for children with CMC. Results: The psychometric evaluation confirmed an acceptable standard for reliability and validity and feasibility. Intensity scores were highest for nursing care related to infection control, medication administration, nutrition, diaper changes, hygiene, neurological and respiratory support, and standing program. Conclusions: Development of a psychometrically sound measure of nursing intensity will help evaluate and plan nursing care for children with CMC.

Abstract

Objectives To systematically review longitudinal studies examining the association between oral health and cognitive decline. Design Studies published between January 1993 and March 2013 were identified by search of English language publications in PubMed/Medline using relevant Medical Subject Heading terms and title and abstract keywords and from CINAHL using relevant subject headings. After applying eligibility criteria and adding four studies identified from article references, 56 of the 1,412 articles identified remained; 40 were cross-sectional, and 16 were longitudinal; 11 of the latter examined the effect of oral health on change in cognitive health or dementia incidence, five examined the reverse. Setting Sources of information included administrative data, subject evaluations in parent studies, medical and dental records, self-reports, and in-person evaluations. Participants Older adults. Measurements Most studies used subjects whose oral or cognitive status was known, using standard approaches to impute for missing information. The oral health information most frequently studied included number of teeth, periodontal and caries problems, and denture use. Cognition was most frequently evaluated using the Mini-Mental State Examination or according to a diagnosis of dementia. Results Some studies found that oral health measures such as number of teeth and periodontal disease were associated with risk of cognitive decline or incident dementia, whereas others did not find an association. Similarly, cognitive decline was not consistently associated with greater loss of teeth or number of decayed teeth. It is likely that methodological limitations play a major role in explaining the inconsistent findings. Conclusion It is unclear how or whether oral health and cognitive status are related. Additional research is needed in which there is greater agreement on how oral health and cognitive states are assessed to better examine the linkages between these two health outcomes.

Abstract

Background: To date, no investigators have examined electronically recorded self-weighing behavior beyond 9 months or the underlying mechanisms of how self-weighing might impact weight change. Objective: Our aims were to examine electronically recorded self-weighing behavior in a weight-loss study and examine the possible mediating effects of adherence to energy intake and energy expenditure (EE) goals on the association between self-weighing and weight change. Design: This was a secondary analysis of the self-efficacy enhancement arm of the Self Efficacy Lifestyle Focus (SELF) trial, an 18-month randomized clinical trial. Participants/setting: The study was conducted at the University of Pittsburgh (2008-2013). Overweight or obese adults with at least one additional cardiovascular risk factor were eligible. Intervention: Participants in the self-efficacy enhancement arm were given a scale (Carematix, Inc) and instructed to weigh themselves at least 3 days per week or every other day. The scale date- and time-stamped each weighing episode, storing up to 100 readings. Main outcome measures: Weight was assessed every 6 months. Adherence to energy intake and EE goals was calculated on a weekly basis using paper diary data. Statistical analyses performed: Linear mixed modeling and mediation analyses were used. Results: The sample (n=55) was 80% female, 69% non-Hispanic white, mean (standard deviation) age was 55.0 (9.6) years and body mass index (calculated as kg/m2) was 33.1 (3.7). Adherence to self-weighing declined over time (P<0.001). From baseline to 6 months, there was a significant mediation effect of adherence to energy intake (P=0.02) and EE goals (P=0.02) on the association between adherence to self-weighing and percent weight change. Mediation effects were not significant during the second and third 6-month periods of the study. Conclusions: Objectively measured adherence to self-weighing declined over 18 months. During the first 6 months, self-weighing directly impacted weight change and indirectly impacted weight change through changes in energy intake and EE.

Abstract

Background: Preventable harm continues to be one of the leading causes of patient death. Each year about 400,000 patients die from sepsis, hospital acquired infections, venous thromboembolism, and pulmonary embolism. However, as shown in the recent reduction in hospital acquired infections, the number of deaths could be reduced if healthcare providers used evidence-based therapies, which are often included in clinical practice guidelines (CPGs). Purpose: The purpose of this integrative review is to appraise and synthesize the current literature on barriers to and facilitators in the use of clinical practice guidelines (CPGs) by registered nurses. Design: Whittemore and Knafl integrative review methodology was used. Primary quantitative and qualitative studies about the nurses' use of CPGs and published in peer-reviewed journals between January 2000 and August 2015 were included. Methods: The Critical Skills Appraisal Program (CASP) was used to critically appraise the quality of sixteen selected quantitative and qualitative studies. Results: Internal factors were attitudes, perceptions, and knowledge whereas format and usability of CPGs, resources, leadership, and organizational culture were external factors influencing CPG use. Conclusion: Given each barrier and facilitator, interventions and policies can be designed to increase nurses' use of CPGs to deliver more evidence based therapy. In order to improve the use of CPGs and to ensure high quality care for all patients, nurses must actively participate in development, implementation, and maintenance of CPGs.

Abstract

Objectives: To systematically identify, appraise, and summarize research on the effects of behavioral interventions to prevent cognitive decline in community-dwelling older adults using a holistic wellness framework. Design: Systematic review of randomized controlled trials that tested the effectiveness of behavioral interventions within each of the six dimensions of wellness: occupational, social, intellectual, physical, emotional and spiritual. Databases searched included PubMed MEDLINE, EMBASE, CENTRAL, PsycINFO, CINAHL, ALOIS, and The Grey Literature Report through July 1, 2014. Setting: Community. Participants: Individuals aged 60 and older (N = 6,254). Measurements: Consolidated Standards of Reporting Trials Checklist. Results: Eighteen studies met the inclusion criteria. Interventions in the physical dimension of wellness were most common (11 studies); interventions in the spiritual dimension were least common (0 studies). Fifty-nine different measures were used to measure multiple cognitive domains, with memory being the most commonly measured (17 studies) and language being the least commonly measured (5 studies). Fifty percent of the interventions examined in the 18 studies demonstrated statistically significant outcomes on at least one cognitive measure. Interventions in the intellectual dimension that examined cognitively stimulating activities using pen and paper or a computer represented the greatest percentage of statistically significant outcomes. Conclusion: Intellectual and physical interventions were most studied, with varied results. Future research is needed using more-consistent methods to measure cognition. Researchers should include the National Institutes of Health Toolbox Cognition Battery among measurement tools to facilitate effective data harmonization, pooling, and comparison.

Abstract

Objectives Identification of biologic pathways of symptom clusters is necessary to develop precision therapies for distressing symptoms. This review examined extant literature evaluating relationships between biomarkers and symptom clusters in cancer survivors. Data Sources PubMed, CINAHL, Web of Science and Cochrane Library were searched using terms “biological markers” or “biomarkers” and “symptom cluster” or “symptom complex” or “multiple symptoms.” Conclusion Biomarkers related to inflammation (eg, cytokines) were the most studied and showed the most significant relationships with clusters of symptoms. This review suggests that clustering of symptoms related to cancer or cancer therapy is linked to immune/inflammatory pathways. Implications for Nursing Practice Understanding the etiology of symptom clusters may guide future nursing interventions for symptom management.

Abstract

Long tolerated as a rite of passage into adulthood, bullying is now recognized as a major and preventable public health problem. The consequences of bullying—for those who are bullied, the perpetrators of bullying, and the witnesses—include poor physical health, anxiety, depression, increased risk for suicide, poor school performance, and future delinquent and aggressive behavior. Despite ongoing efforts to address bullying at the law, policy, and programmatic levels, there is still much to learn about the consequences of bullying and the effectiveness of various responses. In 2016, the National Academies of Sciences, Engineering, and Medicine published a report entitled Preventing Bullying Through Science, Policy and Practice, which examined the evidence on bullying, its impact, and responses to date. This article summarizes the report’s key findings and recommendations related to bullying prevention.

Abstract

Employers are uniquely situated to assist regulators by monitoring nurses practicing with conditions and restrictions resulting from a discipline order by a regulator. However, attitudes, perceptions, and contextual factors may impact employers' participation, and their education and training needs must be considered. A quality-improvement study was conducted to target these areas and provide direction to regulators in developing education and outreach efforts for employers.

Abstract

Adults with type 1 diabetes (T1D) are at risk for cardiovascular (CV) disease. Managing CV risk is an important prevention strategy. The American Heart Association has defined 7 factors for ideal CV health. The purpose of this 2016 secondary analysis was to assess the prevalence of 6 CV health factors in a sample of adults ≥ 18 (n = 7153) in the T1D Exchange Clinic registry. CV health factors include: hemoglobin A1c (HbA1c) < 7%, BMI < 25 kg/m2, blood pressure < 120/80 mm Hg, total cholesterol < 200 mg/dL, non-smoking, and physical activity ≥ 150 min/week. HbA1c < 7% was substituted for the AHA health factor of fasting blood glucose. Frequencies of each factor were tabulated for the total sample and for each gender. Logistic regression examined variables associated with achievement of each CV health factor. The mean age was 37.14 ± 17 years. Mean HbA1c was 7.9 ± 1.5%, and duration was 19.5 ± 13.5 years. The majority (54%) were working full or part-time. Achievement of CV health factors in the whole sample ranged from 27% (HbA1c < 7%) to 94% nonsmoking. Achievement of some factors varied by gender. Common variables associated with several CV health factors included gender, education, employment, and T1D duration. This young sample exhibited low levels of some CV health factors, especially HbA1c and physical activity. Providers need to routinely assess and advise on management of all CV risk factors to prevent this common diabetes complication.

Abstract

Background Sequential and cell-free DNA (cfDNA) screening are both tests for the common aneuploidies. Although cfDNA has a greater detection rate (DR) for trisomy 21, sequential screening also can identify risk for other aneuploidies. The comparative DR for all chromosomal abnormalities is unknown. Objective To compare sequential and cfDNA screening for detection of fetal chromosomal abnormalities in a general prenatal cohort. Study Design The performance of sequential screening for the detection of chromosome abnormalities in a cohort of patients screened through the California Prenatal Screening Program with estimated due dates between August 2009 and December 2012 was compared with the estimated DRs and false-positive rates (FPRs) of cfDNA screening if used as primary screening in this same cohort. DR and FPR for cfDNA screening were abstracted from the published literature, as were the rates of "no results" in euploid and aneuploid cases. Chromosome abnormalities in the entire cohort were categorized as detectable (trisomies 13, 18, and 21, and sex chromosome aneuploidy), or not detectable (other chromosome abnormalities) by cfDNA screening. DR and FPR were compared for individual and all chromosome abnormalities. DR and FPR for the cohort were compared if "no results" cases were considered "screen negative" or "screen positive" for aneuploidy. DR and FPR rates were compared by use of the Fisher exact test. Results Of 452,901 women who underwent sequential screening during the time period of the study, 2575 (0.57%) had a fetal chromosomal abnormality; 2101 were detected for a DR of 81.6%, and 19,929 euploid fetuses had positive sequential screening for an FPR rate of 4.5%. If no results cases were presumed normal, cfDNA screening would have detected 1820 chromosome abnormalities (70.7%) with an FPR of 0.7%. If no results cases were considered screen positive, 1985 (77.1%) cases would be detected at a total screen positive rate of 3.7%. In either case, the detection rate of sequential screening for all aneuploidies in the cohort was greater than cfDNA (P<.0001). Conclusion For primary population screening, cfDNA provides lower DR than sequential screening if considering detection of all chromosomal abnormalities. Assuming that no results cfDNA cases are high-risk improves cfDNA detection but with a greater FPR. cfDNA should not be adopted as primary screening without further evaluation of the implications for detection of all chromosomal abnormalities and how to best evaluate no results cases.
