Background Deaf American Sign Language (ASL) users face communication and language barriers that limit healthcare communication with their providers. Prior research has not examined preventive ...services with ASL-skilled clinicians. Purpose The goal of this study was to determine whether provider language concordance is associated with improved receipt of preventive services among deaf respondents. Methods This cross-sectional study included 89 deaf respondents aged 50–75 years from the Deaf Health Survey (2008), a Behavioral Risk Factor Surveillance System survey adapted for use with deaf ASL users. Association between the respondent's communication method with the provider (i.e., categorized as either concordant–doctor signs or discordant–other) and preventive services use was assessed using logistic regression adjusting for race, gender, income, health status, health insurance, and education. Analyses were conducted in 2010. Results Deaf respondents who reported having a concordant provider were more likely to report a greater number of preventive services (OR=3.42, 95% CI=1.31, 8.93, p =0.0122) when compared to deaf respondents who reported having a discordant provider even after adjusting for race, gender, income, health status, health insurance, and education. In unadjusted analyses, deaf respondents who reported having a concordant provider were more likely to receive an influenza vaccination in the past year (OR=4.55, p =0.016) when compared to respondents who had a discordant provider. Conclusions Language-concordant patient–provider communication is associated with higher appropriate use of preventive services by deaf ASL users.
Abstract Background Micronutrient intake is critical for fetal development and positive pregnancy outcomes. Little is known about the adequacy of micronutrient intake in pregnant African-American ...women. Objective To describe nutrient sufficiency and top food groups contributing to dietary intake of select micronutrients in low-income pregnant African-American women and determine whether micronutrient intake varies with early pregnancy body mass index (BMI) and/or gestational weight gain. Design Secondary analysis of data collected in a cohort study of pregnant African-American women. Participants/setting A total of 93 women aged 18 to 36 years, <20 weeks pregnant, with early pregnancy BMIs ≥18.5 and <40.0. The study was conducted during 2008 to 2012 with participants from university-affiliated obstetrics clinics in an urban setting in the northeastern United States. Main outcome measures Proportion of women with dietary intakes below Estimated Average Requirement (EAR) or Adequate Intake (AI) for vitamin D, folate, iron, calcium, and choline throughout pregnancy. Top food groups from which women derived these micronutrients was also determined. Statistical analyses performed Descriptive statistics included means, standard deviations, and percentages. Percent of women reaching EAR or AI was calculated. The χ2 test was used to assess micronutrient intake differences based on early pregnancy BMI and gestational weight gain. Results A large percentage of pregnant women did not achieve the EAR or AI from dietary sources alone; EAR for folate (66%), vitamin D (100%), iron (89%), and AI for choline (100%). Mean micronutrient intake varied throughout pregnancy. Top food sources included reduced-fat milk, eggs, and mixed egg dishes, pasta dishes, and ready-to-eat cereal. Conclusions The majority of study participants had dietary micronutrient intake levels below EAR/AI throughout pregnancy. Findings suggest that practitioners should evaluate dietary adequacy in women to avoid deficits in micronutrient intake during pregnancy. Top food sources of these micronutrients can be considered when assisting women in improving dietary intake.
Background Food allergy is an important public health problem because it affects children and adults, can be severe and even life-threatening, and may be increasing in prevalence. Beginning in 2008, ...the National Institute of Allergy and Infectious Diseases, working with other organizations and advocacy groups, led the development of the first clinical guidelines for the diagnosis and management of food allergy. A recent landmark clinical trial and other emerging data suggest that peanut allergy can be prevented through introduction of peanut-containing foods beginning in infancy. Objectives Prompted by these findings, along with 25 professional organizations, federal agencies, and patient advocacy groups, the National Institute of Allergy and Infectious Diseases facilitated development of addendum guidelines to specifically address the prevention of peanut allergy. Results The addendum provides 3 separate guidelines for infants at various risk levels for the development of peanut allergy and is intended for use by a wide variety of health care providers. Topics addressed include the definition of risk categories, appropriate use of testing (specific IgE measurement, skin prick tests, and oral food challenges), and the timing and approaches for introduction of peanut-containing foods in the health care provider's office or at home. The addendum guidelines provide the background, rationale, and strength of evidence for each recommendation. Conclusions Guidelines have been developed for early introduction of peanut-containing foods into the diets of infants at various risk levels for peanut allergy.
Background Although fatty acid intake has been associated with risk of coronary disease events, the association between blood omega-6 and trans fatty acids (FAs) at the time of an acute coronary ...syndrome (ACS) is unknown. Methods The relationship of blood FA composition to ACS was analyzed in 768 incident cases and 768 controls (matched on age, sex, and race). Results Compared to controls, ACS cases' blood cell membrane content of linoleic acid was 13% lower ( P < .0001); arachidonic acid was 3.6% higher ( P < .001); the trans isomer of oleic acid was 13.3% higher ( P < .0001); and the trans-trans isomer of linoleic acid was 13.3% higher ( P = .003). In multivariable analyses, a 1-SD decrease in linoleic acid was associated with >3 times the odds for being a case (odds ratio OR 3.23, 95% confidence interval CI 2.63-4.17). The relationship of arachidonic acid to ACS was U shaped; compared to the first quartile of arachidonic acid, the ORs for case status in the second, third, and fourth quartiles were 0.73 (95% CI 0.47-1.13), 0.65 (95% CI 0.41-1.04), and 2.32 (95% CI 1.39-3.90), respectively. The OR for a 1-SD increase in trans oleic acid was 1.24 (95% CI 1.06-1.45), and for trans-trans linoleic acid, 1.1 (95% CI 0.93-1.30). All associations were independent of membrane omega-3 FA content. Conclusions High blood levels of linoleic acid but low levels of trans oleic acid are inversely associated with ACS. The relationship of arachidonic acid to ACS appears more complex.
Abstract Research dating back to the 1950s reported an association between the consumption of saturated fatty acids (SFAs) and risk of coronary heart disease. Recent epidemiological evidence, ...however, challenges these findings. It is well accepted that the consumption of SFAs increases low-density lipoprotein cholesterol (LDL-C), whereas carbohydrates, monounsaturated fatty acids (MUFAs), and polyunsaturated fatty acids (PUFAs) do not. High-density lipoprotein (HDL)-C increases with SFA intake. Among individuals who are insulin resistant, a low-fat, high-carbohydrate diet typically has an adverse effect on lipid profiles (in addition to decreasing HDL-C, it also increases triglyceride and LDL particle concentrations). Consequently, a moderate fat diet in which unsaturated fatty acids replace SFAs and carbohydrates are not augmented is advised to lower LDL-C; compared with a low-fat diet, a moderate-fat diet will lower triglycerides and increase HDL-C. Now, there is some new evidence that is questioning the health benefits of even MUFAs and PUFAs. In addition, in a few recent studies investigators have also failed to demonstrate expected cardiovascular benefits of marine-derived omega-3 fatty acids. To clarify the clinical pros and cons of dietary fats, the National Lipid Association held a fatty acid symposium at the 2011 National Lipid Association Scientific Sessions. During these sessions, the science regarding the effects of different fatty acid classes on coronary heart disease risk was reviewed.

Abstract Heart disease remains the leading cause of death in the United States despite decades of advancement in its diagnosis and treatment. Because of the limitations of traditional risk ...stratification for heart disease, evaluation of the retinal vasculature has been proposed as an easily and safely measured adjunct to commonly used screening methods. This article provides a comprehensive review of the literature concerning the relationships between retinal microvascular abnormalities and coronary heart disease. We outline details of the most recent large epidemiologic studies and discuss their potential implications for clinical practice. Finally, we propose a change to the current guidelines regarding the screening of “low-risk” women, a group that is often failed by traditional evaluation algorithms.
Abstract Huntington disease is an autosomal-dominant neurodegenerative disorder characterized by behavioral abnormalities, cognitive decline, and involuntary movements that lead to a progressive ...decline in functional capacity, independence, and ultimately death. The pathophysiology of Huntington disease is linked to an expanded trinucleotide repeat of cytosine-adenine-guanine (CAG) in the IT-15 gene on chromosome 4. There is no disease-modifying treatment for Huntington disease, and novel pathophysiological insights and therapeutic strategies are needed. Lipids are vital to the health of the central nervous system, and research in animals and humans has revealed that cholesterol metabolism is disrupted in Huntington disease. This lipid dysregulation has been linked to specific actions of the mutant huntingtin on sterol regulatory element binding proteins that result in lower cholesterol levels in affected areas of the brain with evidence that this depletion is pathologic. Huntington disease is also associated with a pattern of insulin resistance characterized by a catabolic state, resulting in weight loss and a lower body mass index than individuals without Huntington disease. Insulin resistance appears to act as a metabolic stressor attending disease progression. The fish-derived omega-3 fatty acids, eicosapentaenoic acid and docosahexaenoic acid, have been examined in clinical trials of Huntington disease patients. Drugs that combat the dysregulated lipid milieu in Huntington disease may help treat this perplexing and catastrophic genetic disease.
