Dietary strategies for cardiovascular health

Apolipoprotein B and Cardiovascular Disease: Biomarker and Potential Therapeutic Target

Apolipoprotein (apo) B, the critical structural protein of the atherogenic lipoproteins, has two major isoforms: apoB48 and apoB100. ApoB48 is found in chylomicrons and chylomicron remnants with one apoB48 molecule per chylomicron particle. Similarly, a single apoB100 molecule is contained per particle of very-low-density lipoprotein (VLDL), intermediate density lipoprotein, LDL and lipoprotein(a). This unique one apoB per particle ratio makes plasma apoB concentration a direct measure of the number of circulating atherogenic lipoproteins. ApoB levels indicate the atherogenic particle concentration independent of the particle cholesterol content, which is variable. While LDL, the major cholesterol-carrying serum lipoprotein, is the primary therapeutic target for management and prevention of atherosclerotic cardiovascular disease, there is strong evidence that apoB is a more accurate indicator of cardiovascular risk than either total cholesterol or LDL cholesterol. This review examines multiple aspects of apoB structure and function, with a focus on the controversy over use of apoB as a therapeutic target in clinical practice. Ongoing coronary artery disease residual risk, despite lipid-lowering treatment, has left patients and clinicians with unsatisfactory options for monitoring cardiovascular health. At the present time, the substitution of apoB for LDL-C in cardiovascular disease prevention guidelines has been deemed unjustified, but discussions continue.

Factors influencing the nutritional behavior of Syrian migrants in Germany - results of a qualitative study

Background

Syrian migrants represent the third-largest group of foreigners in Germany and are therefore potential users of health promotion initiatives, including nutrition programs. It is little known how (healthy) nutrition is understood and implemented by this group and which factors influence their experiences related to food and eating in the host country. Thus, this study aimed to explore the importance of (healthy) nutrition, facilitators, and barriers of a preferred diet; nutritional changes in relation to the country of origin; and how nutrition may change with increasing length of stay.

Methods

Thirty semi-structured qualitative interviews with Syrian migrants (male = 16, female = 14, 18–35 years, length of stay 10–68 months) were conducted in 2018. Seventeen migrants could be followed-up after 12 months and were interviewed in 2019 again and were asked for changes in their nutritional behavior. Interviews were conducted in German, English, or Arabic, transcribed and translated into English if necessary. For analysis, an abbreviated version of the Grounded Theory was used.

Results

We identified six overarching themes that described influencing factors on a favored diet in Germany over the course of stay: (1) managing everyday life; (2) intercultural contact with local residents; (3) social context of cooking and eating; (4) ambiguity toward Arabic food; (5) mistrust toward certain types of food; and (6) influence of postmigration stressors. In general, the importance of nutrition is high among Syrian migrants. However, daily stressors, the lack of practical knowledge of how to cook favored dishes, and food insecurity in the new food environment make it difficult to obtain a preferred diet. With increasing stay, many developed a higher awareness of healthy eating, mainly due to a new independence or influences from the social environment in Germany.

Conclusion

Results highlight the need for health promotion interventions to be more responsive to the specific needs of Syrian migrants, including nutrition. Syrian migrants differ in their capabilities, needs, and aims, and they should be addressed differently by health professionals, social services or migrant specific services. Future research should continue to focus on the living conditions of Syrian migrants and its influence on nutrition.

Multimorbidity Trends in United States Adults, 1988-2014

IMPORTANCE

The simultaneous presence of multiple conditions in one patient (multi-morbidity) is a key challenge facing primary care.

OBJECTIVE

The purpose of this study was to determine the prevalence of multi-morbidity and to document changes in prevalence during the last 25 years.

DESIGN/SETTING

Cross-sectional study using multiple years (1988-2014) of the National Health and Nutrition Examination Survey (NHANES) were analyzed.

SETTING

Multiple years (1988 to 2014) of the National Health and Nutrition Examination Survey (NHANES) from the United States were analyzed.

PARTICIPANTS

Noninstitutionalized adults.

MAIN OUTCOMES AND MEASURES

Number of chronic conditions per individual analyzed by age, race, gender, and socioeconomic factors.

RESULTS

A total of 57,303 individuals were surveyed regarding the presence of multi-morbidity in separate surveys spanning 1988-2014. The overall current prevalence in 2013-2014 of >2 morbidities was 59.6% (95% CI 58.1%-61.1%), 38.5% had 3 or more, and 22.7% had 4 or more morbidities, which was significantly higher than in 1988 (45.7%, 95% CI 43.5%-47.8%, with >2 morbidities). Among individuals with 2 or more morbidities, 54.1% have obesity compared to 41.9% in 1988. Among adults age >65, prevalence was 91.8% for 2 or more morbidities. Whites and Blacks had significantly higher prevalence (59.2% and 60.1%) than Hispanic or "other" race (45.0%, P < .0001). Women (58.4%) had more current multi-morbidities (>2) than men (55.9%, P = .01).

CONCLUSIONS AND RELEVANCE

Multimorbidity is common and has been increasing over the last 25 years. This finding has implications for public health policy and anticipated health costs for the coming years.
