Thyroid function, adipokines and mitokines in metabolic dysfunction-associated steatohepatitis: A multi-centre biopsy-based observational study.

BACKGROUND AND AIMS: Thyroid axis is currently under investigation as a therapeutic target in metabolic dysfunction-associated steatotic liver disease (MASLD). Thyroid function was examined herein in the full spectrum of disease. METHODS: Subjects were recruited and had liver biopsies in two Gastroenterology-Hepatology Clinics (Greece and Australia) and one Bariatric-Metabolic Surgery Clinic (Italy). The main working sample was n = 677 subjects with MASLD after excluding subjects with abnormal free thyroxine levels. Participants were classified according to thyroid-stimulating hormone (TSH) standard criteria: Subclinical hyperthyroidism (<0.4 uIU/mL); Euthyroidism with relatively low (0.4 to <2.5 uIU/mL); euthyroidism with relatively high (2.5-4.0 uIU/mL); subclinical hypothyroidism (>4 uIU/mL). RESULTS: TSH as a continuous variable was positively associated with significant fibrosis (F ≥ 2), metabolic dysfunction-associated steatohepatitis (MASH) and at-risk MASH. Subclinical hypothyroidism was associated with fibrosis F ≥ 2 (odds ratio [OR] = 3.47, 95% confident interval [CI] [1.50, 8.05], p = .02), MASH (OR = 3.44, 95% CI [1.48, 7.98] p = .001) and at-risk MASH (OR = 3.88, 95% CI [1.76, 8.55], p = .001), before and after controlling for adiposity, central obesity, and insulin resistance. When leptin, adiponectin, or growth differentiation factor-15 were examined as moderators, significance was lost. Sex-specific analysis revealed a strong association between TSH and the presence of significant fibrosis among women, eliminated only when adipokines/mitokines were adjusted for. Restricted cubic spline analysis revealed associations between TSH and liver outcomes (p-values < .01) with inflection points for fibrosis F ≥ 2 being 2.49, for MASH being 2.67 and for at-risk MASH being 6.96. CONCLUSIONS: These observations provide support for studies on the administration of thyroid hormone in MASLD therapeutics for subclinical hypothyroidism and liver-specific thyroid receptor agonists for subjects across the TSH continuum.

The role of skeletal muscle mass on cardiovascular disease risk: an emerging role on modulating lipid profile.

PURPOSE OF REVIEW: The purpose of this review was to present updated evidence on the role of skeletal muscle mass on cardiometabolic health. RECENT FINDINGS: Increased lean, and especially skeletal, muscle mass has been associated with better cardiometabolic health in various epidemiological studies, even in younger age groups. In addition, the link between skeletal muscle mass and adult lipid profile is of interest. A preliminary analysis using the data from the ATTICA prospective cohort study (2002-2022) supports this association. SUMMARY: Skeletal muscle mass has many metabolic functions (i.e., glucose, insulin and protein metabolism, mitochondrial function, arterial stiffness, inflammation, oxidative stress, brain function, hormone status). Given its associations with the lipid profile and overall cardiometabolic risk, skeletal muscle mass stands among the emerging risk factors for cardiovascular diseases. In addition to only using body mass index or fat distribution, more studies should evaluate lean mass and its prognostic and predictive ability regarding chronic diseases.

Circulating levels of proglucagon-derived peptides are differentially regulated by the glucagon-like peptide-1 agonist liraglutide and the centrally acting naltrexone/bupropion and can predict future weight loss and metabolic improvements: A 6-month long interventional study.

AIM: To investigate the changes of circulating levels of all proglucagon-derived peptides (PGDPs) in individuals with overweight or obesity receiving liraglutide (3 mg) or naltrexone/bupropion (32/360 mg), and to explore the association between induced changes in postprandial PGDP levels and body composition, as well as metabolic variables, after 3 and 6 months on treatment. MATERIALS AND METHODS: Seventeen patients with obesity or with overweight and co-morbidities, but without diabetes, were assigned to receive once-daily oral naltrexone/bupropion 32/360 mg (n = 8) or once-daily subcutaneous liraglutide 3 mg (n = 9). Participants were assessed before treatment initiation and after 3 and 6 months on treatment. At the baseline and 3-month visits, participants underwent a 3-hour mixed meal tolerance test to measure fasting and postprandial levels of PGDPs, C-peptide, hunger and satiety. Clinical and biochemical indices of metabolic function, magnetic resonance-assessed liver steatosis and ultrasound-assessed liver stiffness were measured at each visit. RESULTS: Both medications improved body weight and composition, carbohydrate and lipid metabolism, and liver fat and function. Naltrexone/bupropion produced a weight-independent increase in the levels of proglucagon (P < .001) and decreases in glucagon-like peptide-2 (GLP-2), glucagon and the major proglucagon fragment (P ≤ .01), whereas liraglutide markedly upregulated total glucagon-like peptide-1 (GLP-1) levels in a weight-independent manner (P = .04), and similarly downregulated the major proglucagon fragment, GLP-2 and glucagon (P < .01). PGDP levels at the 3-month visit were positively and independently correlated with improvements in fat mass, glycaemia, lipaemia and liver function, and negatively with reductions in fat-free mass, at both the 3- and 6-month visits. CONCLUSIONS: PGDP levels in response to liraglutide and naltrexone/bupropion are associated with improvements in metabolism. Our study provides support for the administration of the downregulated members of the PGDP family as replacement therapy (e.g. glucagon), in addition to the medications currently in use that induced their downregulation (e.g. GLP-1), and future studies should explore whether the addition of other PGDPs (e.g. GLP-2) could offer additional benefits.

Barriers and facilitators to health care access for people experiencing homelessness in four European countries: an exploratory qualitative study.

BACKGROUND: People experiencing homelessness (PEH) are known to be at higher risk of adverse health outcomes and premature mortality when compared to the housed population and often face significant barriers when attempting to access health services. This study aimed to better understand the specific health care needs of PEH and the barriers and facilitators associated with their timely and equitable access to health services in the European context. METHODS: We conducted an exploratory cross-national qualitative study involving people with lived experience of homelessness and health and social care professionals in Austria, Greece, Spain, and the UK. A total of 69 semi-structured interviews comprising 15 social care professionals, 19 health care professionals, and 35 PEH were completed, transcribed, and analysed thematically. RESULTS: Findings were organised into three overarching themes relating to the research question: (a) Health care needs of PEH, (b) Barriers to health care access, and (c) Facilitators to health care access. Overall, the general health of PEH was depicted as extremely poor, and mainstream health services were portrayed as ill-equipped to respond to the needs of this population. Adopting tailored approaches to care, especially involving trusted professionals in the delivery of care, was identified as a key strategy for overcoming existing barriers. CONCLUSIONS: The results of this study indicate there to be a high degree of consistency in the health care needs of PEH and the barriers and facilitators associated with their access to health care across the various European settings. Homelessness in itself is recognized to represent an essential social determinant of health, with PEH at risk of unequal access to health services. Changes are thus required to facilitate PEH's access to mainstream primary care. This can also be further complemented by investment in 'in-reach' services and other tailored and person-centred forms of health care. TRIAL REGISTRATION: This study was registered retrospectively on June 6, 2022, in the registry of ClinicalTrials.gov under the number NCT05406687.

The association of specific types of vegetables consumption with 10-year type II diabetes risk: Findings from the ATTICA cohort study.

BACKGROUND: The present study aimed to investigate the association between vegetable consumption, in total as well as per type/category, and 10-year type-2 diabetes mellitus (T2DM) incidence. METHODS: The ATTICA study was conducted during 2001-2012 in 3042 apparently healthy adults living in Athens area, Greece. A detailed biochemical, clinical, and lifestyle evaluation was performed; vegetable consumption (total, per type) was evaluated through a validated semi-quantitative food frequency questionnaire. After excluding those with no complete information of diabetes status or those lost at the 10-year follow-up, data from 1485 participants were used for the current analysis. RESULTS: After adjusting for several participants' characteristics, including overall dietary habits, it was observed that participants consuming at least 4 servings/day of vegetables had a 0.42-times lower risk of developing T2DM (hazard ratio [HR] = 0.42; 95% confidence interval [CI] = 0.29-0.61); the benefits of consumption were greater in women (HR = 0.29; 95% CI = 0.16-0.53) compared to men (HR = 0.56; 95% CI = 0.34-0.92). Only 33% of the sample consumed vegetables 4 servings/day. The most significant associations were observed for allium vegetables in women and for red/orange/yellow vegetables, as well as for legumes in men. CONCLUSIONS: The intake of at least 4 servings/day of vegetables was associated with a considerably reduced risk of T2DM, independently of other dietary habits; underlying the need for further elaboration of current dietary recommendations at the population level.

Adherence to a Mediterranean type of diet in the world: a geographical analysis based on a systematic review of 57 studies with 1,125,560 participants.

This systematic review aimed to assess the level and time-trends of adherence to Mediterranean-type diets (MTD) among the general population, globally. According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses, a comprehensive literature search of the MEDLINE and Scopus databases was carried out, until 04/09/2023, based on specific criteria. Fifty-seven studies with 1,125,560 apparently healthy adults from Europe (n = 37), US (n = 8), Asia (n = 8), Australia (n = 4) and Africa (n = 1) were included. Adherence to an MTD was moderate with a significant decline observed in the last decade. European countries, mainly driven by Mediterranean countries, showed higher adherence than other regions. Geographical analysis revealed that adherence to an MTD is related to both geographic location and socioeconomic status throughout the world.

Dietary patterns, caloric restrictions for management of cardiovascular disease and cancer; a brief review.

Cardiovascular disease (CVD) and cancers are overall still identified as the two most prevalent non-communicable diseases globally. Their prevention and potential reversal (in particular CVD risk) was seen effective with the modification of dietary intake that was applied in several different populations. Although the findings from epidemiological studies provide support that adhering to dietary patterns such as the Mediterranean diet can reduce incidence and prevalence of CVD and some forms of cancer, the mechanistic aspects of disease modulation associated with both diseases can be seen in dietary management. Several studies have already explored the potential modes of action of certain nutrients in well controlled large clinical trials. However, the clinical trials designed to determine the effects of adhering to a particular diet are relatively hard to conduct and these studies are faced with several obstacles particularly in the populations that are identified with a high risk of CVD or different cancers. Therefore, it is important to understand potential underlying and shared mechanisms of action and to explore how healthy dietary patterns may modulate the occurrence, initiation, and progression of such diseases. The aim of this review is to summarise and conceptualize the current understanding relating to healthy dietary patterns, and briefly discuss the opportunities that epigenetic research may bring and how it may assist to further interpret epidemiological and clinical evidence.

Quality of plant-based diets in relation to 10-year cardiovascular disease risk: the ATTICA cohort study.

PURPOSE: We prospectively evaluated the association between quality of plant-based diets and 10-year first fatal/non-fatal cardiovascular disease (CVD) incidence. METHODS: ATTICA study was conducted in the greater metropolitan Athens area, Greece, during 2001-2002 studying men and women (aged > 18 years old) free of CVD at baseline. Follow-up CVD assessment (2011-2012) was achieved in n = 2,020 participants (n = 317 cases). Dietary assessment was based on a validated semi-quantitative paper-based food frequency questionnaire. Overall, healthful, and unhealthful plant-based dietary indices (PDI, hPDI and uPDI) were calculated through a standard published procedure. The association between plant-based indices and CVD outcome has been evaluated via Cox regression analysis. RESULTS: The CVD event rate was 15.7% (n = 317) with a median follow-up time of 8.41 years. The highest (3rd PDI tertile) vs. lowest (1st tertile) adherence to plant-based pattern-irrespective to healthfulness of food products consumed-was inversely associated with CVD (hazard ratio (HR) 0.56; 95% confidence interval (95% CI) 0.14, 2.25) yet the CI was wide. Ranking from 1st to 2nd and 3rd hPDI tertile the CVD event rate was 6.4%, 10.5% and 16.2%, respectively (p = 0.003). Multi-variable adjusted analysis revealed that participants assigned in 2nd and 3rd hPDI tertile had 47% (HR 0.53; 95% CI 0.25-1.08) and 68% (HR 0.32; 95% CI 0.16-0.63) lower risk to develop CVD compared with their 1st tertile counterparts. Conversely, a positive association between uPDI and CVD risk was revealed in dose-response analysis (HR(per 5 units increase in uPDI) 1.34; 95% CI 0.95-2.37)). CONCLUSIONS: Quality of plant-based diets is important and needs to be considered, as not all plant-source foods have beneficial cardiovascular effects.

Meat consumption, depressive symptomatology and cardiovascular disease incidence in apparently healthy men and women: highlights from the ATTICA cohort study (2002-2012).

Objectives: To evaluate the association of meat consumption with prevalent depressive symptomatology and cardiovascular disease (CVD) incidence in apparently healthy individuals.Methods: ATTICA study was conducted during 2001-2012 including n = 1514 men and n = 1528 women (aged >18 years old) from the greater Athens area, Greece. At baseline, depressive symptomatology through Zung Self-Rating Depression Scale (range 20-80) and meat consumption (total meat, red, white and processed meat) through validated semi-quantitative food frequency questionnaire were assessed. Follow-up (2011-2012) was achieved in n = 2020 participants (n = 317 cases); n = 845 participants with complete psychological metrics were used for the primary analysis.Results: Ranking from 1st to 3rd total meat consumption (low to high) tertiles, participants assigned in 2nd tertile had the lowest depressive-symptomatology scoring (p<0.001). This trend was retained in multiadjusted logistic regression analysis; participants reporting moderate total and red meat consumption had ∼20% lower likelihood to be depressed (i.e. Zung scale<45) compared with their 1st tertile counterparts (Odds Ratio (OR)total meat 0.82, 95% Confidence Interval (95%CI) (0.60, 0.97) and ORred meat 0.79 95%CI (0.45, 0.96)). Non-linear associations were revealed; 2-3 serving/week total meat and 1-2 servings/week red meat presented the lowest odds of depressive symptomatology (all ps<0.05). These U-shape trends seemed to attenuate the aggravating effect of depressive symptomatology on CVD hard endpoints. All aforementioned associations were more evident in women (all ps for sex-related interaction<0.05).Discussion: The present findings generate the hypothesis that moderate total meat consumption and notably, red meat may be more beneficial to prevent depressed mood and in turn hard CVD endpoints.

Digital Health Interventions for Weight Management in Children and Adolescents: Systematic Review and Meta-analysis.

BACKGROUND: Recent meta-analyses suggest the use of technology-based interventions as a treatment option for obesity in adulthood. Similar meta-analytic approaches for children are scarce. OBJECTIVE: The aim of this meta-analysis is to examine the effect of technology-based interventions on overweight and obesity treatment in children and adolescents. METHODS: A systematic literature search was performed using MEDLINE (PubMed), Scopus, and Cochrane Library for randomized clinical trials to identify interventional studies published between January 2000 and February 2021. RESULTS: In total, 9 manuscripts from 8 clinical trials of 582 children or adolescents were considered eligible. BMI, BMI z-score, and other BMI-related baseline metrics during and after intervention were considered as primary outcomes. In 7 of 8 studies, a technology-based intervention was applied in addition to conventional care. Of the 8 studies, 6 studies were conducted in the United States, 1 in Australia, and 1 in northwestern Europe. In total, 5 studies included adolescents, whereas the rest addressed children aged 9 to 12 years. Intervention duration ranged from 3 to 24 months. Significant differences between groups in BMI metric changes were reported by 5 of the 8 studies. Pooled analysis revealed an overall significant decrease in BMI metrics in the intervention group (standardized mean difference -0.61, 95% CI -1.10 to -0.13; P=.01). Subgroup analysis revealed that significance was lost in case of no parental involvement (standardized mean difference -0.36, 95% CI -0.83 to 0.11; P=.14). The small number of clinical trials found, the varying study quality, and the study heterogeneity are some limitations of this review. CONCLUSIONS: The studies reported herein describe functional and acceptable technology-based approaches, in addition to conventional treatments, to enhance weight loss in young populations.

The association between serum uric acid levels and 10-year cardiovascular disease incidence: results from the ATTICA prospective study.

Limited data suggests possible gender-specific association between serum uric acid (SUA) and cardiovascular disease (CVD) incidence. The aim of the present analysis was to evaluate the association between SUA levels and 10-year CVD incidence (2002-2012) in the ATTICA study participants. Overall, 1687 apparently healthy volunteers, with SUA measurements, residing in the greater metropolitan Athens area (Greece), were included. Multivariable Cox-regression models were used to estimate the hazard ratios for SUA in relation to 10-year CVD incidence. Receiver operating curve analysis was conducted to detect optimal SUA cut-off values. Participants in the 2nd and 3rd SUA tertile had 29 and 73% higher 10-year CVD incidence compared with those in the 1st tertile (p < 0.001). In gender-specific analysis, only in women SUA was independently associated with CVD incidence; women in the 3rd SUA tertile had 79% greater 10-year CVD event risk compared to their 1st tertile counterparts. Obese in the 3rd SUA tertile had 2-times higher CVD incidence compared to those in the 1st tertile. Similar findings were observed in metabolically healthy (vs. unhealthy) and metabolically healthy obese. SUA thresholds best predicting 10-year CVD incidence was 5.05 and 4.15 mg/dL (0.30 and 0.25 mmol/L) in men and women, respectively. In conclusion, increased SUA levels were independently related to 10-year CVD event rate in women, obese and metabolically healthy individuals. SUA could predict 10-year CVD incidence even at low levels. Further studies are warranted to identify SUA cut-off values that may improve the detection of individuals at higher CVD risk in clinical practice.

The validity of technology-based dietary assessment methods in childhood and adolescence: a systematic review.

Technology-based dietary assessment has promising benefits on improving accuracy and reducing cost of dietary data collection. The validity of technology-based tools in children/adolescents was examined. A systematic literature search was performed to identify studies published till September 2019. In total, 26 studies with 29 validation-related estimations were selected; 13 web-based 24-hdietary recalls (image assisted; n = 12, drop-down food list; n = 13), 4 mobile applications and 3 web-based dietary records (image based; n = 2 and image assisted; n = 1, drop-down food list; n = 3) and 6 web-based food frequency questionnaires (FFQs) (image assisted; n = 3). Fourteen studies were addressed to adolescents, ten studies to children (principally 9-11 years old) and two studies to mixed study samples. Validation was mostly performed through 24-h dietary recalls and dietary records while in some cases objective methods were used. Image-assisted 24-h dietary recalls presented good level of agreement with paper-based methods, yet principally in adolescents. Mobile-application dietary records with image-based facilities and drop-down food lists were found to accurately record dietary intake even when compared with objective methods. FFQs, mainly examined in adolescents, had good level of agreement with the "gold standard" dietary records method. The validity of technology-based methods could be supported yet various technical/methodological issues need better clarification.

The impact of socioeconomic and environmental determinants on Mediterranean diet adherence: a municipal-level spatial analysis in Athens metropolitan area, Greece.

The aim of this study was to identify the geographical variability, the socio-economic and the environmental determinants of adherence to the Mediterranean diet in a general population sample. Level of adherence to the Mediterranean diet was estimated by the ATTICA epidemiological study for 2,749 participants, while socio-economic, demographic, and environmental characteristics were provided by official national and international databases. Higher adherence to the Mediterranean diet was detected in areas with a greater proportion of females and older people, with lower unemployment rate and immigrant population, as well as, in areas covered at a greater extent by green and with higher frequency of supermarkets and street markets. The present findings provide evidence for policy makers to better understand how layers of influence intersect to shape individuals' eating habits, while they may also contribute in identifying areas of emerging interventions needed.

Feeding the preterm infant: an overview of the evidence.

Feeding from own mother's milk is not always an option for preterm infants, and choosing between alternative means of feeding should be made in light of their effect on infants' health. In this work, we aimed to present evidence regarding feeding pre-term infants with human milk, either own mother's or donor milk (DM), and the potential effects on growth and other health related outcomes. Exclusive breastfeeding (BF) remains the optimal option, whereas feeding with DM as a sole diet or supplemental to maternal milk confers immunological advantages and fewer rates of necrotising enterocolitis against preterm formula feeding, yet the latter results in greater growth velocity. Literature gaps in the use of DM, practical suggestions for choosing suitable feeding means (i.e. continuous support of BF, adequate education regarding feeding preterm infants, including DM), and future perspectives on the potential effects of dietary manipulations of the maternal diet, are also discussed.

Dairy products, surrogate markers, and cardiovascular disease; a sex-specific analysis from the ATTICA prospective study.

BACKGROUND AND AIMS: Dairy products are a very diverse food group with multiple effects on the cardiac health of men and women. The aim of this work was to evaluate the sex-specific association between dairy products (total and subtypes) and 10-year first fatal/nonfatal cardiovascular disease (CVD) incidence. METHODS AND RESULTS: In 2001-2002, n = 1514 men and n = 1528 women (>18 years old) from greater Athens area, Greece, were enrolled. Dietary assessment was based on a validated semi-quantitative food frequency questionnaire. Dairy product consumption was examined in relation to 10-year CVD incidence. Follow-up (2011-2012) was achieved in n = 2020 participants (n = 317 CVD cases). Ranking from lowest (<1 serving/day) to highest (>2 servings/day) total dairy intake, CVD incidence in men was 17.8%, 15.0%, and 10.9% (p = 0.41), while in women it was 14%, 6.0%, and 5.7% (p = 0.02). Multiadjusted analysis revealed that total dairy intake protected against CVD only in women [Hazard Ratio (HR) = 0.48 and 95% Confidence Interval (95% CI) (0.23, 0.90)], irrespective of the fat content. Further analysis revealed that only fermented products (yogurt and cheese), protected against CVD. For per 200 g/day yogurt consumption, CVD risk was 20%-30% lower with this claim being more evident in women, while for per 30 g/day cheese intake, about 5% lower risk was observed particularly in men. As for butter, nonsignificant associations were highlighted. These associations were mainly retained in the case of hepatic steatosis, insulin resistance, and systemic inflammation. CONCLUSIONS: This work provides incentives for researchers to elucidate the diversity of ingredients and mechanisms through which dairy products exert their effect on cardiac health separately for men and women.

Sex-Related Differences of the Effect of Lipoproteins and Apolipoproteins on 10-Year Cardiovascular Disease Risk; Insights from the ATTICA Study (2002-2012).

The sex-specific effect of lipid-related biomarkers on 10-year first fatal/non fatal cardiovascular disease (CVD) incidence was evaluated. ATTICA study was conducted during 2001-2012. n = 1514 men and n = 1528 women (>18 years) from greater Athens area, Greece were recruited. Follow-up (2011-2012) was achieved in n = 2020 participants. Baseline lipid profile was measured. Overall CVD event was 15.5% (n = 317) (19.7% in men and 11.7% in women, p < 0.001). High density lipoprotein cholesterol (HDL-C) and triglycerides (TAG) were independently associated with CVD in women; per 10 mg/dL HDL-C increase, hazard ratio (HR) = 0.73, 95% confidence interval (95% CI) (0.53, 1.00); and per 10 mg/dL TAG increase, HR = 1.10, 95% CI (1.00, 1.21). Apolipoprotein A1 (ApoA1) (per 10 mg/dL increase, HR = 0.90, 95% CI (0.81, 0.99)) was inversely associated with CVD in women, while a positive association with apolipoprotein B100 (ApoB100) was observed only in men (per 10 mg/dL increase, HR = 1.10, 95% CI (1.00, 1.21)). Non-HDL-C was associated with CVD in the total sample (HR = 1.10, 95% CI (1.00, 1.21)) and in women (HR = 1.10, 95% CI (1.00, 1.21)); a steep increase in HR was observed for values >185 mg/dL in the total sample and in men, while in women, a raise in CVD risk was observed from lower values (>145 mg/dL). As for non-HDL-C/HDL-C and TC/HDL-C ratios, similar trends were observed. Beyond the common cholesterol-adjusted risk scores, reclassifying total CVD risk according to other lipid markers may contribute to early CVD prevention. Biomarkers such as HDL-C, non-HDL-C, and TAG should be more closely monitored in women.

The role of lipoprotein (a) in primary and secondary cardiovascular disease prevention: a systematic review of epidemiological studies.

PURPOSE OF REVIEW: Lipoprotein (a) [Lp(a)] is highly suggested as an emerging risk factor in cardiovascular disease (CVD) prevention. However, there remains controversy regarding the shape of Lp(a) risk curve and the extent to which Lp(a) confers risk for CVD, independently of conventional lipid markers. This systematic review outlines the current state of knowledge regarding the role of Lp(a) in primary and secondary CVD prevention. RECENT FINDINGS: Searches resulted in the selection of n = 19 studies. In the context of primary CVD prevention, n = 9 cohorts, n = 2 case-cohorts, and n = 2 retrospective studies were identified, the majority of which suggested a significant positive association between Lp(a) and CVD onset. In terms of secondary CVD prevention, n = 5 cohorts and n = 1 case-cohort were considered as eligible highlighting from a positive to a neutral association between Lp(a) and CVD progression. SUMMARY: A positive association between Lp(a) and CVD seems to be supported by a large body of evidence yet it is comparatively moderate in magnitude and differentiates according to study population and the examined endpoints. This fact along with the lack of a definitive functional mechanism limits the potential connotation of Lp(a) in daily clinical practice.

The effects of the Mediterranean diet on rheumatoid arthritis prevention and treatment: a systematic review of human prospective studies.

Rheumatoid arthritis is a progressive autoimmune disease characterised by severely swollen and painful joints. To compliment pharmacotherapy, people living with rheumatoid arthritis often turn to dietary interventions such as the Mediterranean diet. The aim of the present systematic review is to discuss the effects of the Mediterranean diet on the management and prevention of rheumatoid arthritis in human prospective studies. Four studies met the inclusion criteria, including two intervention studies reporting improvement in the pain visual analogue scale (p < 0.05) and a decrease in the health assessment questionnaire for rheumatoid arthritis score (p < 0.05) in the Mediterranean diet groups. Only one study reported a reduction in the 28 joint count disease activity score for rheumatoid arthritis for the Mediterranean diet group (p < 0.05). This review has identified beneficial effects of the Mediterranean diet in reducing pain and increasing physical function in people living with rheumatoid arthritis. However, there is currently insufficient evidence to support widespread recommendation of the Mediterranean diet for prevention of rheumatoid arthritis.

Daily distribution of free healthy school meals or food-voucher intervention? Perceptions and attitudes of parents and educators.

AIMS: To qualitatively evaluate the optimal intervention (food-voucher approach vs. free daily meal distribution), aimed at reducing food insecurity and promoting healthy eating among students attending public schools in socioeconomically disadvantaged areas. METHODS: We randomly assigned 34 schools to one of the two interventions: students in 17 schools received a daily lunch-box and parents in the other 17 schools received a food voucher of equal value once a month. All students were offered the opportunity to participate. We conducted 30 focus groups in all participating schools (17 in the meal distribution and 13 in the food voucher schools). Eligible participants included parents (n = 106), educators (n = 66) and school principals (n = 34). We qualitatively evaluated their perceptions and attitudes towards the program. RESULTS: Important differences were observed between the two approaches, with more favourable perceptions being reported for the meal distribution approach. More specifically, social stigmatization was minimized in the meal distribution approach, through the participation of all students, compared with the food-voucher participants who reported feelings of embarrassment and fear of stigmatization. Secondly, the meal distribution approach alleviated child food insecurity through the provision of the daily meal, while the food-voucher intervention helped manage household food insecurity, as vouchers were mainly used for purchasing food for family meals. Furthermore, the educational and experiential nature of the meal distribution approach intensified healthy eating promotion, while the food-voucher intervention was efficient mainly for conscious parents regarding healthy eating. CONCLUSIONS: The meal distribution intervention was considered more effective than the food-voucher one. Hence, for interventions aiming at tackling food insecurity of children and adolescents, public health focus could be oriented towards school-based in kind food assistance.

Depressive symptomatology in relation to 10-year (2004-2014) acute coronary syndrome incidence; the moderating role of diet and financial status.

BACKGROUND: The association between depression status and 10-year cardiovascular disease (CVD) incidence among acute coronary syndrome (ACS) patients, in relation to nutritional and financial status, was evaluated. METHODS: From October 2003 to September 2004, a sample of 2172 consecutive ACS patients from 6 Greek hospitals was enrolled. In 2013-14, the 10-year follow-up was performed. Depressive symptoms were evaluated using the validated CES-D score (range 0-60). Adherence to Mediterranean diet was assessed through MedDietScore (range 0-55) and financial status was determined by the annual income. RESULTS: Ranking from the 1st to 3rd CES-D tertile, recurrent fatal/non fatal ACS rates were 33%, 37% and 42%, respectively (p=0.006). Multiple logistic regression models revealed an adverse association of severe depression status (i.e. 3rd tertile) compared to no depression (i.e. 1st tertile) [odds ratio (OR)=1.31, 95% confidence interval (95% CI) 1.01, 1.69]. When controlling for financial status, the relationship between depression and ACS prognosis remained marginally significant; while subgroup analysis revealed that only patients with low/moderate income were negatively affected [OR=1.36, 95% CI 0.98, 1.88]. Further stratified analysis, by MedDietScore group, was applied; the above association remained significant only in patients with low compliance to this dietary pattern [OR=1.68, 95% CI 1.10, 2.18]. CONCLUSIONS: ACS coexisting with severe depression status seems to result in adverse disease outcomes while financial status and Mediterranean diet are proposed as potential moderators. Public health programs should focus on vulnerable groups and minimize depressive symptoms through appropriate medical treatment and lifestyle interventions, so as to ameliorate the disease prognosis in clinical and community levels.
