Association of aortic stiffness early post myocardial infarction with left ventricular remodelling.

BACKGROUND: Adverse left ventricular (LV) remodelling after myocardial infarction is associated with heart failure. We investigated whether aortic stiffness during acute ST-segment elevation myocardial infarction is associated with LV remodelling at long-term follow-up. METHODS: In 109 patients within 48 h of myocardial infarction post-primary percutaneous coronary intervention and after 2 years, we measured: (a) carotid to femoral pulse wave velocity (PWV), (b) LV global longitudinal strain (GLS) and left atrial strain using speckle-tracking echocardiography, (c) PWV/GLS ratio as a surrogate marker of ventricular-arterial interaction, and (d) LV end-diastolic and end-systolic volumes. A > 15% decrease from the baseline in LV end-systolic volume at 2-year follow-up was considered as a criterion of reverse LV remodelling. RESULTS: Compared with baseline, all patients had reduced PWV, LV end-diastolic and end-systolic volumes while PWV/GLS, GLS and reservoir left atrial strain were improved (p < .05) after 2 years. Baseline values of PWV, GLS, PWV/GLS ratio and reservoir left atrial strain were associated with percentage change of LV end-systolic volume at 2 years (p < .05). Multivariable analysis revealed that lower baseline values of PWV and a less impaired GLS and PWV/GLS were independently associated with reverse LV remodelling at 2 years with a C-statistic of .748, .711 and .787, respectively. CONCLUSION: Aortic stiffness early post-infarction determines LV remodelling after 2 years of the ischemic event despite post successful revascularization.

The Effect of a Ketogenic Diet versus Mediterranean Diet on Clinical and Biochemical Markers of Inflammation in Patients with Obesity and Psoriatic Arthritis: A Randomized Crossover Trial.

The effect of different diet patterns on psoriasis (PSO) and psoriatic arthritis (PSA) is unknown. Τhe aim of our study was to evaluate the effectiveness of a Mediterranean diet (MD) and Ketogenic diet (KD), in patients with PSO and PSA. Twenty-six patients were randomly assigned to start either with MD or KD for a period of 8 weeks. After a 6-week washout interval, the two groups were crossed over to the other type of diet for 8 weeks. At the end of this study, MD and KD resulted in significant reduction in weight (p = 0.002, p < 0.001, respectively), in BMI (p = 0.006, p < 0.001, respectively), in waist circumference (WC) (p = 0.001, p < 0.001, respectively), in total fat mass (p = 0.007, p < 0.001, respectively), and in visceral fat (p = 0.01, p < 0.001, respectively), in comparison with baseline. After KD, patients displayed a significant reduction in the Psoriasis Area and Severity Index (PASI) (p = 0.04), Disease Activity Index of Psoriatic Arthritis (DAPSA) (p = 0.004), interleukin (IL)-6 (p = 0.047), IL-17 (p = 0.042), and IL-23 (p = 0.037), whereas no significant differences were observed in these markers after MD (p > 0.05), compared to baseline. The 22-week MD-KD diet program in patients with PSO and PSA led to beneficial results in markers of inflammation and disease activity, which were mainly attributed to KD.

Effects of Liraglutide, Empagliflozin and Their Combination on Left Atrial Strain and Arterial Function.

Background and Objectives: Glucagon-like peptide-1 receptor agonists (GLP-1RA) and sodium-glucose cotransporter-2 inhibitors (SGLT-2i) are cardioprotective drugs. We investigated their effects on left atrial function, a major determinant of cardiac diastolic dysfunction in type 2 diabetes mellitus. We also explored the association of changes in arterial stiffness with those of the LA strain after treatment. Materials and Methods: A total of 200 patients (59.5 ± 9.1 year old, 151 male) with type 2 diabetes mellitus treated with metformin were randomized to insulin (n = 50 served as controls), liraglutide (n = 50), empagliflozin (n = 50) or their combination (liraglutide + empagliflozin) (n = 50). We measured at baseline and 6 months post-treatment: (a) left atrial and global left ventricular longitudinal strain by speckle tracking echocardiography; (b) pulse wave velocity (PWV) and central systolic blood pressure. Results: At baseline, there was a correlation of the LA reservoir strain with PWV (r = -0.209, p = 0.008), central SBP (r = -0.151, p = 0.030), EF (r = 0.214, p = 0.004) and GLS (r = -0.279, p = 0.009). The LA reservoir change 6 months post-treatment was correlated with the PWV change in all groups (r = -0.242, p = 0.028). The LA reservoir change 6 months post-treatment was correlated with the GLS change in all groups (r = -0.322, p = 0.004). Six months after intervention, patients treated with liraglutide, empagliflozin and their combination improved the left atrial reservoir strain (GLP1RA 30.7 ± 9.3 vs. 33.9 ± 9.7%, p = 0.011, SGLT2i 30 ± 8.3 vs. 32.3 ± 7.3%, p = 0.04, GLP1&SGLT2i 29.1 ± 8.7 vs. 31.3 ± 8.2, p = 0.007) compared to those treated with insulin (33 ± 8.3% vs. 32.8 ± 7.4, p = 0.829). Also, patients treated with liraglutide and the combination liraglutide and empagliflozin had improved left atrial conduction strain (p < 0.05). Empagliflozin or the combination liraglutide and empagliflozin showed a greater decrease of PWV and central and brachial systolic blood pressure than insulin or GLP-1RA. (p < 0.05). Conclusions: Impaired aortic elastic properties are associated with a decreased LA strain in type 2 diabetics. Treatment with liraglutide, empagliflozin and their combination for 6 months showed a greater improvement of left atrial function compared to insulin treatment in parallel with the improvement of arterial and myocardial functions.

Association of hydroxytyrosol enriched olive oil with vascular function in chronic coronary disease.

BACKGROUND: Hydroxytyrosol reduces low-density lipoprotein oxidation, contributing to prevention of atherosclerosis progression. METHODS: In a prospective, crossover, double-blind, placebo-controlled trial, 30 chronic coronary artery syndrome (CCAS) patients were randomized to 4 capsules/day, containing 412.5 mg olive oil with 2.5 mg hydroxytyrosol (OOHT) each one or placebo for 1 month and then were crossed over to the alternate treatment (placebo or OOHT). We measured (a) perfused boundary region (PBR) of the sublingual arterial microvessels (increased PBR indicates reduced glycocalyx thickness), (b) flow-mediated dilation (FMD), (c) Coronary Flow Reserve (CFR) and markers of LV diastolic function by Doppler echocardiography, (d) pulse wave velocity (PWV), and (e) oxidative stress, inflammatory biomarkers and blood lipids at baseline and after treatment. RESULTS: Treatment with OOHT improved PBR, FMD, CFR and PWV compared to baseline (1.8 ± .3 vs. 1.7 ± .4 µm, p = .040, 3.7 ± 2.1 vs. 6.5% ± 2.3%, p < .001, 2.3 ± .4 vs. 2.5 ± .4, p = .030 and 11.1 ± 1.8 vs. 11.8 ± 2.3 m/s, p = .002) while there was no effect after placebo (p = NS). No effect of OOHT treatment was observed on blood pressure. There was a parallel improvement of E' of the mitral annulus and deceleration time of the E wave of mitral inflow after OOHT (p < .05) but not after placebo. Compared to baseline, treatment with OOHT reduced malondialdehyde, a marker of lipid peroxidation, oxidized LDL, triglycerides, PCSK9 and CRP blood levels (p < .05) in contrast to placebo. CONCLUSIONS: Hydroxytyrosol-enriched olive oil may have beneficial effects on endothelial, arterial and LV diastolic function likely by reducing oxidative and inflammatory burden in CCAS, though further studies are needed to confirm this mechanism.

Exclusion from social relations in later life: on the gendered associations of social networks with mental wellbeing.

Objectives: This study addresses the gendered risks of loneliness and depression in later life from a social exclusion perspective. Exclusion from social relations (ESR) in older age is an unwanted situation associated with increased loneliness and depressive symptoms, with gender differences in the perception of solitude, and the evaluation of existing social networks, potentially accounting for the increased susceptibility of older women.Method: Secondary analyses was conducted in a sample of 60,918 participants in the Survey on Health, Aging and Retirement in Europe (SHARE). Older persons' subjective perception of solitude (i.e. solitude satisfaction), and their satisfaction with established relations (i.e. network satisfaction), were examined in gender-stratified regression models, predicting loneliness and depressive symptomatology, controlling for network size, demographics, and health.Results: There was no convincing evidence for significant associations between solitude satisfaction (SoS) and loneliness among older men, nor between network satisfaction (NeS) and loneliness for both genders. Low SoS and low NeS were independently associated with more depressive symptoms and an increased probability of depression, especially among older women. This vulnerability could not be attributed to increased loneliness, as only among older women, low SoS was associated with lower levels of loneliness, and lower levels of loneliness was anaemically associated with more depressive symptoms.Conclusions: The perception of solitude, and the evaluation of social relations, are associated with gendered risks of depression among older persons who are challenged by objective and subjective ESR states.

An intervention to optimise coach-created motivational climates and reduce athlete willingness to dope (CoachMADE): a three-country cluster randomised controlled trial.

OBJECTIVES: Coach-centred antidoping education is scarce. We tested the efficacy of a motivationally informed antidoping intervention for coaches, with their athletes' willingness to dope as the primary outcome. METHODS: We delivered a cluster randomised controlled trial in Australia, the UK and Greece. This study was a parallel group, two-condition, superiority trial. Participants were 130 coaches and 919 athletes. Coaches in the intervention group attended two workshops and received supplementary information to support them in adopting a motivationally supportive communication style when discussing doping-related issues with their athletes. Coaches in the control condition attended a standard antidoping workshop that provided up-to-date information on antidoping issues yet excluded any motivation-related content. Assessments of willingness to dope (primary outcome) and other secondary outcomes were taken at baseline, postintervention (3 months) and at a 2-month follow up. RESULTS: Compared with athletes in the control group, athletes in the intervention group reported greater reductions in willingness to take prohibited substances (effect size g=0.17) and psychological need frustration (g=0.23) at postintervention, and greater increases in antidoping knowledge (g=0.27) at follow-up. Coaches in the intervention group reported at postintervention greater increases in efficacy to create an antidoping culture (g=0.40) and in perceived effectiveness of need supporting behaviours (g=0.45) to deal with doping-related situations. They also reported greater decreases in doping attitudes (g=0.24) and perceived effectiveness of need thwarting behaviours (g=0.35). CONCLUSIONS: Antidoping education programmes should consider incorporating principles of motivation, as these could be beneficial to coaches and their athletes. We offer suggestions to strengthen these programmes, as most of the effects we observed were not sustained at follow-up. TRIAL REGISTRATION NUMBER: This trial has been registered with the Australian New Zealand Clinical Trials Registry (https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=371465&isReview=true).

A survey on the training needs of caregivers in five European countries.

AIM: This survey explored caregivers' perceived training needs in 5 European countries (United Kingdom, Greece, Bulgaria, Poland and Italy). BACKGROUND: Training can enhance the professional capacity of caregivers; however, caregivers' training needs within Europe have not been examined recently. METHODS: A survey conducted in 2015 captured data from 550 caregivers using a convenience sampling strategy, through a structured questionnaire and additional open-ended items and by conducting statistical and content analysis. RESULTS: The results indicated basic nursing skills and specialization, as well as training in psychology-related skills like time management, emotion regulation, communication and advanced health care systems as the emerging training needs. There were some country differences in specific training need areas. CONCLUSIONS: It was concluded that training in basic nursing skills and specialization in nursing specific conditions, in advanced health care systems and in psychology-related skills could add to the professional capacity of European caregivers employed in health and social care. IMPLICATIONS FOR NURSING MANAGEMENT: The findings inform about employed caregivers' training needs in Europe, which may contribute in the provision of quality care and organisational efficiency in health and social care.

Pulse wave velocity to global longitudinal strain ratio in hypertension.

BACKGROUND: Arterial elastance to left ventricular elastance ratio assessed by echocardiography is widely used as a marker of ventricular-arterial coupling. MATERIALS AND METHODS: We investigated whether the ratio of carotid-femoral pulse wave velocity, as a marker of arterial stiffness, to global longitudinal strain, as a marker of left ventricular performance, could be better associated with vascular and cardiac damage than the established arterial elastance/left ventricular elastance index. In 299 newly-diagnosed untreated hypertensives we measured, carotid-femoral pulse wave velocity, and carotid intima-media thickness, coronary-flow reserve, arterial elastance/left ventricular elastance, global longitudinal strain, and markers of left ventricular diastolic function (E/A and E') by echocardiography. RESULTS: Pulse wave velocity-to-global longitudinal strain ratio (PWV/GLS) was lower in hypertensives than controls (-0.61 ± 0.21 vs -0.45 ± 0.11 m/sec%, P < 0.001). Low PWV/GLS values were associated with carotid-intima media thickness > 0.9 mm (P = 0.003), E/A ≤ 0.8 (P = 0.019) and E' ≤ 9 cm/sec (P = 0.002) and coronary-flow reserve < 2.5 (P = 0.017), after adjustment for age, sex and mean arterial pressure. Low PWV/GLS was also associated with increased left ventricular mass and left atrial volume in the univariate (P = 0.003 and 0.038) but not in the multivariate model. In hypertensives, there was no significant association of arterial elastance-to-left ventricular elastance index with carotid intima media thickness, coronary flow reserve, E/A, E', or left atrial volume with the exception of an inverse association with left ventricular mass (P = 0.027). CONCLUSIONS: Pulse wave velocity-to-global longitudinal strain ratio but not the echocardiography-derived arterial elastance-to left ventricular elastance index is related to impaired carotid-intima media thickness, coronary-flow reserve and diastolic function in hypertensives.

Pulse wave analysis using the Mobil-O-Graph, Arteriograph and Complior device: a comparative study.

PURPOSE: Pulse wave velocity (PWV) is a marker of arterial stiffness with major prognostic value. We compared Arteriograph and Complior devices with the Mobil-O-Graph for assessment of PWV and central systolic blood pressure (cSBP). MATERIALS AND METHODS: We studied 316 consecutive subjects (age: 55 ± 14 years). For each individual, we measured PWV and cSBP with Arteriograph, Complior and Mobil-O-Graph and compared the readings. Differences in values among three devices were calculated for each measurement. We used Bland-Altman analysis, intraclass correlation coefficient (ICC) and coefficient of variation (CV). RESULTS: Bland-Altman analysis indicated a mean difference for PWV: i.0.5 m/s (limits of agreement -1.4-2.4) between Complior and Mobil-O-Graph, ii.0.6 m/s (limits of agreement -1.4-2.6) between Arteriograph and Mobil-O-Graph. cSBP mean difference was 3.8 mmHg between Complior and Mobil-O-Graph (limits of agreement -12.5-20.1) and 9.2 mmHg between Arteriograph and Mobil-O-Graph (limits of agreement -7.6-26). ICC for PWV was 0.86 between Arteriograph and Mobil-O-Graph, 0.87 between Complior and Mobil-O-Graph and for cSBP 0.92 and 0.91 respectively. CV for PWV was 9.5% between Arteriograph and Mobil-O-Graph, 8.8% between Complior and Mobil-O-Graph. Respective values for cSBP were 6.8% and 5.1%. CONCLUSION: Our study shows acceptable agreement among the three devices regarding pulse wave analysis markers though Mobil-O-Graph appears to underestimate the values of these markers. Further studies are needed to explore the agreement between the 3 devices in various clinical settings and patient populations.

Effects of 6-month treatment with the glucagon like peptide-1 analogue liraglutide on arterial stiffness, left ventricular myocardial deformation and oxidative stress in subjects with newly diagnosed type 2 diabetes.

BACKGROUND: Incretin-based therapies are used in the treatment of type 2 diabetes mellitus (T2DM) and obesity. We investigated the changes in arterial stiffness and left ventricular (LV) myocardial deformation after 6-month treatment with the GLP-1 analogue liraglutide in subjects with newly diagnosed T2DM. METHODS: We randomized 60 patients with newly diagnosed and treatment-naive T2DM to receive either liraglutide (n = 30) or metformin (n = 30) for 6 months. We measured at baseline and after 6-month treatment: (a) carotid-femoral pulse wave velocity (PWV) (b) LV longitudinal strain (GLS), and strain rate (GLSR), peak twisting (pTw), peak twisting velocity (pTwVel) and peak untwisting velocity (pUtwVel) using speckle tracking echocardiography. LV untwisting was calculated as the percentage difference between peak twisting and untwisting at MVO (%dpTw-UtwMVO), at peak (%dpTw-UtwPEF) and end of early LV diastolic filling (%dpTw-UtwEDF) (c) Flow mediated dilatation (FMD) of the brachial artery and percentage difference of FMD (FMD%) (d) malondialdehyde (MDA), protein carbonyls (PCs) and NT-proBNP. RESULTS: After 6-months treatment, subjects that received liraglutide presented with a reduced PWV (11.8 ± 2.5 vs. 10.3 ± 3.3 m/s), MDA (0.92 [0.45-2.45] vs. 0.68 [0.43-2.08] nM/L) and NT-proBNP (p < 0.05) in parallel with an increase in GLS (- 15.4 ± 3 vs. - 16.6 ± 2.7), GLSR (0.77 ± 0.2 vs. 0.89 ± 0.2), pUtwVel (- 97 ± 49 vs. - 112 ± 52°, p < 0.05), %dpTw-UtwMVO (31 ± 10 vs. 40 ± 14), %dpTw-UtwPEF (43 ± 19 vs. 53 ± 22) and FMD% (8.9 ± 3 vs. 13.2 ± 6, p < 0.01). There were no statistically significant differences of the measured markers in subjects that received metformin except for an improvement in FMD. In all subjects, PCs levels at baseline were negatively related to the difference of GLS (r = - 0.53) post-treatment and the difference of MDA was associated with the difference of PWV (r = 0.52) (p < 0.05 for all associations) after 6-month treatment. CONCLUSIONS: Six-month treatment with liraglutide improves arterial stiffness, LV myocardial strain, LV twisting and untwisting and NT-proBNP by reducing oxidative stress in subjects with newly diagnosed T2DM.

Tree uptake of excess nutrients and herbicides in a maize-olive tree cultivation system.

Due to the extent of non-point source agricultural pollution, protective measures to control agrochemicals from entering aquatic systems are necessary. Measures may include, among others, vegetated buffer strips (VFS), no spray buffer zones, alley crops and agroforestry systems (AFS). The scope of the present work is to examine the pollution abatement potential of a maize-olive (MO) AFS. The efficiency of a combined MO trees system in reducing nutrients and herbicides is tested through soil monitoring in an experimental plot, located in Koropi, Eastern Attica, Greece, in the period May 2015 to November 2015. The monitored pollutants were nitrogen and phosphorus, as well as two herbicides: pendimethalin and nicosulfuron. Soil samples were collected every 3-5 weeks at various soil horizons and distances from the tree row. Pollutant concentrations were determined using liquid chromatography tandem mass spectrometry (LC-MS/MS), ion chromatography (IC) and spectrophotometry techniques. The studied MO tree system exhibited the potential to reduce pollutant migration, with removals ranging 36.8-78.9% for [Formula: see text], 79.3-100% for [Formula: see text], 76.7-100% for [Formula: see text], 79.4-100% for [Formula: see text] and 70-100% for the examined herbicides. The higher removal percentages were observed in the upper soil layers (5-35 cm, below the crops), and where the finer tree roots extend. Thus, the results indicate that planting of trees in cultivated fields can contribute to the reduction of agrochemical pollution of the subsurface soil and in extension of groundwater.

Occurrence and distribution of trifluralin, ethalfluralin, and pendimethalin in soils used for long-term intensive cotton cultivation in central Greece.

In the present study, a soil monitoring program was undertaken in Greek cotton cultivated areas in 2012. Twenty-seven soil samples were collected from the entire Thessaly plain in early summer of 2012, corresponding to approximately three months (current use of pendimethalin), up to one year (for the banned ethalfluralin), and three years (for the also banned trifluralin), after the last dinitroaniline application. Low but not negligible levels of dinitroanilines were detected, ranging from 0.01 to 0.21 µg g-1 d.w. for trifluralin and 0.01-0.048 µg g-1 d.w. for pendimethalin, respectively. Trifluralin was the herbicide most frequently detected (44.4%). The high historic application of trifluralin and its high persistence and accumulation potential is in line with the abundance of the detected residues. The present data indicate that soil samples contain extractable residues of banned trifluralin, but based on the comparison of the theoretical PECplateau for trifluralin (0.277 µg g-1) and the maximum Measured Environmental Concentration, it was concluded that the detected residues should be attributed to previous years' application. The latter suggested the need for continual monitoring of the dinitroaniline family of pesticides, including the banned substances, aiming thus to an improved environmental profile for agricultural areas.

Monocular Depth Estimation: A Thorough Review.

Estimation of depth in two-dimensional images is among the challenging topics in Computer Vision. This is a well-studied but also an ill-posed problem, which has long been the focus of intense research. This paper is an in-depth review of the topic, presenting two aspects, one that considers the mechanisms of human depth perception, and another that includes the various Deep Learning approaches. The methods are presented in a compact and structured way that outlines the topic and categorizes the approaches according to the line of research followed in the recent decade. Although there has been significant advancement in the topic, it was without any connection with human depth perception and the potential benefits from this sector.

Evaluation of cardiovascular risk factors in children aged 6-16 years and their evolution in early adulthood in a 10-year follow-up study.

OBJECTIVE: Obesity and arterial hypertension (AH) in children represent well-recognized risk factors for cardiovascular (CV) events during adult life. We investigated any changes regarding several CV risk (CVR) factors in children after a 10-year follow-up period. METHODS: A cohort of 143 healthy children, elementary/high school students, 6-16 years old, was initially evaluated in 2010-2011 regarding CVR factors [obesity, blood pressure (BP), aortic stiffness (PWV), lipid profile] plus food habits/sports activity. At 10-years follow-up (2020-2021), 63/143 (44%) young adults were re-evaluated. RESULTS: Children with obesity (45%) had increased BP (p < 0.001) and a less favorable LDL-C/triglycerides profile (p = 0.001) compared to overweight/normoweight ones. In a 10-year follow-up, obesity and exercise improved (p < 0.001 and p = 0.005), systolic BP (SBP) (102 ± 13 vs. 118 ± 11 mmHg, p < 0.001) and PWV increased (6.1 ± 1 vs. 7.7 ± 1.1 m/sec, p < 0.001), LDL-C (96 ± 21 vs. 86 ± 24 mg/dl, p = 0.004) and HDL-C + (64 ± 18 vs. 55 ± 10 mg/dl, p < 0.001) decreased, triglycerides increased (62 ± 21 vs. 73 ± 34 mg/dl, p = 0.04), and food approached the western model of nutrition (less fish/fruits). In children/young adults, BMI was associated with age (Beta = 0.47, p < 0.001 and Beta = 0.36, p = 0.004), SBP (Beta = 0.46 and Beta = 0.52, p < 0.001), and LDL-C (Beta = 0.27 and Beta = 0.44, p < 0.001). CONCLUSIONS: In children with obesity, increased BMI and waist circumference were related to SBP and a less favorable lipid profile. At the 10-year re-evaluation, obesity was partially improved, physical activity was increased, and SBP had reached the high-normal levels in a substantial number of young adults, while lipid profile was less favorable (for HDL-C/triglycerides) compared to baseline evaluation. Our results highlight the evolution of CVR factors from childhood to early adulthood.

Mechanisms of Vascular Inflammation and Potential Therapeutic Targets: A Position Paper From the ESH Working Group on Small Arteries.

Inflammatory responses in small vessels play an important role in the development of cardiovascular diseases, including hypertension, stroke, and small vessel disease. This involves various complex molecular processes including oxidative stress, inflammasome activation, immune-mediated responses, and protein misfolding, which together contribute to microvascular damage. In addition, epigenetic factors, including DNA methylation, histone modifications, and microRNAs influence vascular inflammation and injury. These phenomena may be acquired during the aging process or due to environmental factors. Activation of proinflammatory signaling pathways and molecular events induce low-grade and chronic inflammation with consequent cardiovascular damage. Identifying mechanism-specific targets might provide opportunities in the development of novel therapeutic approaches. Monoclonal antibodies targeting inflammatory cytokines and epigenetic drugs, show promise in reducing microvascular inflammation and associated cardiovascular diseases. In this article, we provide a comprehensive discussion of the complex mechanisms underlying microvascular inflammation and offer insights into innovative therapeutic strategies that may ameliorate vascular injury in cardiovascular disease.

Sense-Making of Loneliness and Exclusion From Social Relations Among Older Adults in Sweden.

BACKGROUND AND OBJECTIVES: Loneliness and exclusion from social relations (ESR) are frequently addressed as public health issues for older adults. Public discourses potentially influence how loneliness and ESR are understood in society and experienced by the individual. The aim of this study was to analyze how older adults in different parts of Sweden use the discourses and concepts available to them to describe experiences of ESR and loneliness, and how these descriptions are used to construct a self-identity. RESEARCH DESIGN AND METHODS: Qualitative semi-structured interviews were conducted with 30 individuals (14 men, 16 women) aged 67-87 years and living in Sweden. Emphasis was, in line with perspectives of discursive psychology, on how individuals draw on discourses to make sense of experiences. The empirical material was analyzed through an inductive process where we were open to finding concepts and themes. RESULTS: Most participants emphasized the importance of not being lonely, considered achievable through maintaining an active lifestyle. "Othering" was taking place, where a general image of a "lonely" older adult was referred to when speaking about "others" loneliness. Those who expressed feelings of loneliness related these feelings to loss, being omitted, and other difficult life circumstances. DISCUSSION AND IMPLICATIONS: States of ESR were discussed more comfortably than loneliness, whereas various linguistic resources were used to distance themselves from loneliness. These findings indicate the need for further studies elaborating on how older adults make sense of ESR and loneliness and what implications this has for older adults' well-being and identity making.

The status of organochlorine pesticide contamination in Greek agricultural soils: the ghost of traditional agricultural history.

Inadequate information regarding pesticide contamination in Greek agricultural soils is currently available, while national soil monitoring programs have not been initiated yet. The aim of the present study was to assess the levels, compositions, and distribution of thirty three organochlorine pesticides (OCPs) in Greek agricultural soils, due to the environmental threat posed by these compounds, even after decades from their abrogation from the market. Determination of the organochlorine pesticides was achieved using gas-chromatography-mass spectrometry, following a QuEChERS sample preparation method. A total of 60 soil samples, from two soil horizons (up to 60 cm), were obtained from agricultural lands in Greece throughout 2019-2020. The major findings presented DDTs, γ-HCH, alachlor, and 4,4- DCBP in the examined soil samples, with DDTs being the major compounds with their maximum cumulative concentration (ΣDDTs) reaching 1273.4 µg kg-1 d.w. Compositional profile and diagnostic ratios suggested that the occurrence of DDT residues was due to historical inputs. Most of the samples did not exceed the target values set by the Netherlands and Canadian guidelines for DDTs in soil; however, there was one exception in the case of Aegina Island. Finally, based on the environmental exposure assessment conducted, the vast majority of the analytes presented lower concentrations compared to the predicted environmental concentrations, with an exemption for DDE metabolite where the measured and predicted concentrations were almost equal.

Evaluation of Antibody Kinetics Following COVID-19 Vaccination in Greek SARS-CoV-2 Infected and Naïve Healthcare Workers.

We investigated the antibody kinetics after vaccination against COVID-19 in healthcare workers of a Greek tertiary hospital. Eight hundred and three subjects were included, of whom 758 (94.4%) received the BNT162b2 vaccine (Pfizer-BioNTech), eight (1%) mRNA-1273 (Moderna), 14 (1.7%) ChAdOx1 (Oxford-AstraZeneca) and 23 (2.9%) Ad26.COV2.S (Janssen). Before the second dose, at 2, 6 and 9 months after the second dose and at 2 and 6 months after the third dose, anti-spike IgG were quantified by the chemiluminescence microparticle immunoassay method. One hundred subjects were infected before vaccination (group A), 335 were infected after receiving at least one vaccine dose (group B), while 368 had never been infected (group C). Group A presented a greater number of hospitalizations and reinfections compared to group B (p < 0.05). By multivariate analysis, younger age was associated with an increased risk of reinfection (odds ratio: 0.956, p = 0.004). All subjects showed the highest antibody titers at 2 months after the second and third dose. Group A showed higher antibody titers pre-second dose, which remained elevated 6 months post-second dose compared to groups B and C (p < 0.05). Pre-vaccine infection leads to rapid development of high antibody titer and a slower decline. Vaccination is associated with fewer hospitalizations and fewer reinfections.

Additive prognostic value of longitudinal myocardial deformation to SCORE2 in psoriasis.

Aims: Psoriasis has been associated with increased cardiovascular (CV) risk. We investigated whether markers of CV function and their change after treatment have a prognostic value for adverse outcomes. Methods and results: In a prospective study, at baseline and after 6 months of treatment with biological agents, we assessed in 298 psoriasis patients (i) left ventricular global longitudinal strain (GLS) and (ii) carotid-femoral pulse wave velocity (PWV), to evaluate their prognostic value for major adverse cardiovascular events (MACEs), including coronary artery disease, stroke, hospitalization for heart failure, and all-cause death over a 4-year follow-up period. During follow-up, 26 (8.7%) MACEs were recorded. By univariate analysis, decreasing absolute GLS values [hazard ratio (HR): 0.73, P < 0.001], decreasing GLS change after treatment (HR: 0.53, P = 0.008), and increasing PWV values (HR: 1.16, P = 0.049) were associated with adverse outcomes. Baseline GLS and its change post-treatment remained independent predictors of adverse events after adjusting for several confounders (P < 0.05). The addition of baseline GLS and its absolute change post-treatment to SCORE2 increased Harrell's C from 0.882 to 0.941. By multivariable analysis, for each 1% increase in absolute baseline GLS values, the risk of MACE decreased by 33% and for each 1% absolute increase of GLS post-treatment compared with the baseline value, the risk of MACE decreased by 58%. Conclusion: Global longitudinal strain has an independent and additive prognostic value to SCORE2 for adverse CV events in psoriasis, providing timely decision-making for intensive anti-inflammatory treatment and aggressive modification of risk factors to reduce CV risk.
