- Diversity in the genetic profile between individuals and specific ethnic groups affects nutrient requirements, metabolism and response to nutritional and dietary interventions. Indeed, individuals respond differently to lifestyle interventions (diet, physical activity, smoking, etc.). The sequencing of the human genome and subsequent increased knowledge regarding human genetic variation is contributing to the emergence of personalized nutrition. These advances in genetic science are raising numerous questions regarding the mode that precision nutrition can contribute solutions to emerging problems in public health, by reducing the risk and prevalence of nutrition-related diseases. Current views on personalized nutrition encompass omics technologies (nutrigenomics, transcriptomics, epigenomics, foodomics, metabolomics, metagenomics, etc.), functional food development and challenges related to legal and ethical aspects, application in clinical practice, and population scope, in terms of guidelines and epidemiological factors. In this context, precision nutrition can be considered as occurring at three levels: (1) conventional nutrition based on general guidelines for population groups by age, gender and social determinants; (2) individualized nutrition that adds phenotypic information about the person's current nutritional status (e.g. anthropometry, biochemical and metabolic analysis, physical activity, among others), and (3) genotype-directed nutrition based on rare or common gene variation. Research and appropriate translation into medical practice and dietary recommendations must be based on a solid foundation of knowledge derived from studies on nutrigenetics and nutrigenomics. A scientific society, such as the International Society of Nutrigenetics/Nutrigenomics (ISNN), internationally devoted to the study of nutrigenetics/nutrigenomics, can indeed serve the commendable roles of (1) promoting science and favoring scientific communication and (2) permanently working as a 'clearing house' to prevent disqualifying logical jumps, correct or stop unwarranted claims, and prevent the creation of unwarranted expectations in patients and in the general public. In this statement, we are focusing on the scientific aspects of disciplines covering nutrigenetics and nutrigenomics issues. Genetic screening and the ethical, legal, social and economic aspects will be dealt with in subsequent statements of the Society.

- Nutrigenetics considers the influence of individual genetic variation on differences in response to dietary components, nutrient requirements and predisposition to disease. Nutrigenomics involves the study of interactions between the genome and diet, including how nutrients affect the transcription and translation process plus subsequent proteomic and metabolomic changes, and also differences in response to dietary factors based on the individual genetic makeup. Personalized characteristics such as age, gender, physical activity, physiological state and social status, and special conditions such as pregnancy and risk of disease can inform dietary advice that more closely meets individual needs. Precision nutrition has a promising future in treating the individual according to their phenotype and genetic characteristics, aimed at both the treatment and prevention of disease. However, many aspects are still in progress and remain as challenges for the future of nutrition. The integration of the human genotype and microbiome needs to be better understood. Further advances in data interpretation tools are also necessary, so that information obtained through newer tests and technologies can be properly transferred to consumers. Indeed, precision nutrition will integrate genetic data with phenotypical, social, cultural and personal preferences and lifestyles matters to provide a more individual nutrition, but considering public health perspectives, where ethical, legal and policy aspects need to be defined and implemented.

Tidskriftsartikel (refereegranskat)abstract
- Background: The risks of thromboembolic and hemorrhagic events in patients with atrial fibrillation both increase with age; therefore, net clinical benefit analyses of anticoagulant treatments in the elderly population are crucial to guide treatment. We evaluated the 1-year clinical outcomes with non-vitamin-K antagonist and vitamin K antagonist oral anticoagulants (NOACs vs VKAs) in elderly (≥75 years) patients with atrial fibrillation in a prospective registry setting. Methods: Data on 3825 elderly patients were pooled from the PREFER in AF and PREFER in AF PROLONGATION registries. The primary outcome was the incidence of the net composite endpoint, including major bleeding and ischemic cardiovascular events on NOACs (n = 1556) compared with VKAs (n = 2269). Results: The rates of the net composite endpoint were 6.6%/year with NOACs vs 9.1%/year with VKAs (odds ratio [OR] 0.71; 95% confidence interval [CI], 0.51-0.99; P =.042). NOAC therapy was associated with a lower rate of major bleeding compared with VKA use (OR 0.58; 95% CI, 0.38-0.90; P =.013). Ischemic events were nominally reduced too (OR 0.71; 95% CI, 0.51-1.00; P =.050). Major bleeding with NOACs was numerically lower in higher-risk patients with low body mass index (BMI; OR 0.50; 95% CI, 0.22-1.12; P =.07) or with age ≥85 years (OR 0.44; 95% CI, 0.13-1.49; P =.17). Conclusions: Our real-world data indicate that, compared with VKAs, NOAC use is associated with a better net clinical benefit in elderly patients with atrial fibrillation, primarily due to lower rates of major bleeding. Major bleeding with NOACs was numerically lower also in higher-risk patients with low BMI or age ≥85 years.

- Studies evaluating the relationship between platelet indices and cardiovascular (CV) outcomes yielded conflicting results. We assessed the incidence of adverse events according to baseline quintiles of platelet indices in the prospective cohort of the Malmö Diet and Cancer Study. A total of 30,314 individuals (age 57 ± 8 years) were followed for a median of 16 years (468,490 person-years). Outcome measures included all-cause death, CV death, myocardial infarction (MI), and ischemic stroke. The fifth quintile of platelet count (> 274.6 × 109/L) was associated with higher incidence of all-cause death (hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.09-1.32, p < 0.001), CV death (HR 1.19, 95% CI 1.00-1.42; p = 0.044), MI (HR 1.32, 95% CI 1.12-1.54; p = 0.001), and ischemic stroke (HR 1.27, 95% CI 1.08-1.50, p = 0.004) compared with the first quintile (≤ 185 × 109/L), and also associated with a lower survival, regardless of previous history of MI (p for interaction = 0.58) or stroke (p for interaction = 0.42). In the highest quintile, history of stroke had a higher risk of CV death (HR 3.18, 95% CI 1.54-6.54) compared with no previous stroke (HR 1.12, 95% CI 0.96-1.31). The risk of MI and stroke was greatest in the fifth quintile, regardless of previous MI or previous stroke, respectively. The risk of all adverse events was similar across different quintiles of mean platelet volume. In conclusion, elevated platelet count is associated with higher mortality and risk of CV events, regardless of previous MI and stroke. Platelet count may thus be a useful marker for further stratification of CV risk, and especially of death.

- Background Risk factors included in the cardiovascular (CHA2DS2‐VASc) score, currently used for atrial fibrillation (AF), may predispose to cardiovascular events whether or not AF is present. The aim was to explore the predictive role of CHA2DS2‐VASc score on cardiovascular outcomes in diabetic patients without AF. Methods We accessed individual data from 610 diabetic patients without AF at baseline included in the prospective cohort of the Malmö Diet and Cancer study. Main outcome measure was the occurrence of cardiovascular events (stroke, coronary events) and death. Mean follow‐up was 14.5 ± 5 years (8845 person/years). Results The CHA2DS2‐VASc score significantly predicted the risk of all outcome measures. There was a significant increase in stroke, coronary events, and death risk by each point of CHA2DS2‐VASc score elevation [stroke: adjusted hazard ratio (aHR) 1.43, 95% CI 1.14‐1.79, P = 0.001; coronary events: aHR 1.55, 95% CI 1.34‐1.80, P < 0.0001; death: aHR 1.94, 95% CI 1.71‐2.21, P < 0.0001]. A CHA2DS2‐VASc score ≥4 was associated with higher incidence of ischemic stroke (aHR 1.47, 95% CI 1.18‐1.82; P = 0.001), coronary events (aHR 1.32; 95% CI 1.11‐1.58; P = 0.002), and death (aHR 1.36; 95% CI 1.20‐1.54; P < 0.001). Conclusions In this population‐based study on diabetic patients without AF, the CHA2DS2‐VASc score was an independent predictor of ischemic stroke, coronary events, and overall mortality. Regardless of the AF status, the CHA2DS2‐VASc score might represent a rapid and user‐friendly tool for clinical assessment of diabetic patients at higher cardiovascular risk.

- AIMS: The CHA2DS2VASc score is used to evaluate the risk of thromboembolic events in patients with non-valvular atrial fibrillation. We assessed the prognostic yield of CHA2DS2VASc for new-onset atrial fibrillation, cardiovascular morbidity and mortality in a non-atrial fibrillation population.METHODS: We analysed a population-based cohort of 22,179 middle-aged individuals with (n = 3542) and without (n = 18,367) a history of atrial fibrillation; we grouped the population into five CHA2DS2VASc strata (0-1-2-3-≥4), and compared the risk of major adverse cerebro-cardiovascular events and mortality. Furthermore, we analysed the annual incidence of atrial fibrillation across different CHA2DS2VASc strata.RESULTS: Over a median follow-up of 15 years, 1572 patients (6.9%) had ischaemic strokes, 2162 (9.5%) coronary events and 5899 (26%) died. The cumulative incidence of ischaemic stroke in CHA2DS2VASc ≥ 4 subjects without atrial fibrillation was similar to patients with atrial fibrillation and CHA2DS2VASc 2, with a 10-year crude incidence rate of 0.91 (95% confidence interval (CI) 0.68-1.19) and 1.13 (95% CI 0.93-1.36) ischaemic strokes per 100 patient-years, respectively. CHA2DS2VASc in a non-atrial fibrillation population showed higher predictive accuracy for ischaemic stroke compared with an atrial fibrillation population (area under the curve 0.60 vs. 0.56; P = 0.001). In multivariable Cox regression analysis, CHA2DS2VASc ≥ 2 was an independent predictor of all-cause death (adjusted hazard ratio (aHR) 2.58; 95% CI 2.42-2.76), cardiovascular death (aHR 3.40; 95% CI 2.98-3.89), ischaemic stroke (aHR 2.20; 95% CI 1.92-2.53) and coronary events (aHR 1.83; 95% CI 1.63-2.04). The cumulative incidence of atrial fibrillation was greater with increasing CHA2DS2VASc strata, with an absolute annual incidence of more than 2% per year if CHA2DS2VASc ≥ 4.CONCLUSION: The CHA2DS2VASc score is a sensitive tool for predicting new-onset atrial fibrillation and adverse outcomes in subjects both with and without atrial fibrillation.

- OBJECTIVE(S):: We explored incidence, predictors, and long-term prognosis of hospital admissions attributed to reflex syncope and orthostatic hypotension. METHODS:: We analyzed a cohort of 32?628 individuals (68.2% men; age, 45.6?±?7.4 years) without prevalent cardiovascular disease over a follow-up period of 26.6?±?7.5 years. RESULTS:: One thousand and fourteen persons (3.1%, 1.2 per 1000 person-years) had at least 1 hospitalization for orthostatic hypotension (n?=?462, 1.42%) or syncope (n?=?632, 1.94%). Orthostatic hypotension-related hospitalizations were predicted by age [per 1-year increase, hazard ratio 1.14, 95% confidence interval (CI): 1.12–1.16], smoking (hazard ratio 1.35, 95% CI: 1.12–1.64), diabetes (hazard ratio 1.50, 95% CI: 1.00–2.25), baseline orthostatic hypotension (hazard ratio 1.45, 95% CI: 1.05–1.98), in particular, by SBP fall at least 30?mmHg (hazard ratio 3.93, 95% CI: 2.14–7.23), whereas syncope hospitalizations by age (per 1-year increase, hazard ratio 1.09, 95% CI: 1.07–1.11), smoking (hazard ratio 1.27, 95% CI: 1.08–1.49), and hypertension (hazard ratio 1.42, 95% CI: 1.20–1.69). Both syncope-hospitalized and orthostatic hypotension hospitalized patients had higher burden of hospital admissions for other reasons such as cardiovascular, pulmonary, renal disease, or diabetes. During the follow-up, 10?727 (32.9%) died, with 419 deaths preceded by syncope/orthostatic hypotension hospitalization. After adjustment for traditional risk factors, syncope-hospitalization predicted all-cause mortality (hazard ratio 1.16, 95% CI: 1.02–1.31), whereas orthostatic hypotension hospitalization predicted cardiovascular mortality (hazard ratio 1.13, 95% CI: 1.07–1.19). CONCLUSION:: Hospital admissions due to syncope and orthostatic hypotension occur in ≈3% of older individuals and increase with age and comorbidities. Admissions due to syncope are associated with prevalent hypertension, whereas those due to orthostatic hypotension overlap with diabetes and previously identified orthostatic hypotension. Syncope-related admissions predict higher all-cause mortality, whereas orthostatic hypotension-related admissions herald increased cardiovascular mortality.

- Orthostatic hypotension (OH) is a common cardiovascular disorder, with or without signs of underlying neurodegenerative disease. OH is diagnosed on the basis of an orthostatic challenge and implies a persistent systolic/diastolic blood pressure decrease of at least 20/10 mm Hg upon standing. Its prevalence is age dependent, ranging from 5% in patients <50 years of age to 30% in those >70 years of age. OH may complicate treatment of hypertension, heart failure, and coronary heart disease; cause disabling symptoms, faints, and traumatic injuries; and substantially reduce quality of life. Despite being largely asymptomatic or with minimal symptoms, the presence of OH independently increases mortality and the incidence of myocardial infarction, stroke, heart failure, and atrial fibrillation. In this review, we outline the etiology and prevalence of OH in the general population, summarize its relationship with morbidity and mortality, propose a diagnostic and therapeutic algorithm, and delineate current challenges and future perspectives.

- Introduction: Cardiac syncope heralds significantly higher mortality compared with syncope due to noncardiac causes or unknown etiology, commonly considered a benign event. A few epidemiologic studies have examined the outcome of noncardiac/unexplained syncope comparing individuals with and without syncope, but with controversial results. We performed a systematic review and meta-analysis to clarify whether history of noncardiac/unexplained syncope is associated with increased all-cause mortality in the general population. Methods and Results: Our systematic review of the literature published between January 1, 1966, and March 31, 2018 sought prospective, observational, cohort studies reporting summary-level outcome data about all-cause mortality in subjects with history of noncardiac/unexplained syncope compared with syncope-free participants. Adjusted hazard ratios were pooled through inverse variance random-effect meta-analysis to compute the summary effect size. Meta-regression models were performed to explore the effect of age, cardiovascular risk factors, or other potential confounders on the measured effect size. We identified four studies including 287 382 individuals (51.6% men; age, 64 ± 12 years): 38 843 with history of noncardiac/unexplained syncope and 248 539 without history of syncope. The average follow-up was 4.4 years. History of noncardiac/unexplained syncope was associated with higher all-cause mortality (pooled adjusted hazard ratio = 1.13; 95% confidence interval, 1.05 to 1.23). Meta-regression analysis showed a stronger positive relationship proportional to aging and increasing prevalence of diabetes and hypertension. Conclusions: This study-level meta-analysis showed that among older, diabetic and/or hypertensive individuals, history of noncardiac/unexplained syncope, even in the absence of an obvious cardiac etiology, is associated with higher all-cause mortality.
