Plant protein substitution for animal protein and its association with cardiovascular risk factors and inflammatory biomarkers in elderly men: A substitution analysis

BACKGROUND: Substituting different types of protein intake may be associated with cardiovascular risk factors and inflammatory biomarkers. However, there are few studies conducted on elders and the findings are contradictory. OBJECTIVE: We decided to examine the association of substituting plant protein for animal protein with cardiovascular risk factors and inflammatory biomarkers among elderly men. METHOD: The current cross-sectional study included 357 elderly men chosen from health centres in southern Tehran, Iran. They provide written consent to be included in the study. We used a validated and reliable food frequency questionnaire (FFQ) to assess dietary intake. All biochemical factors like lipid profile, fasting blood sugar (FBS), high sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL6), tumor necrosis factor-α (TNF-α) were measured. Waist circumference (WC) and blood pressure (BP) were also assessed. The substitution analysis by STATA was used to examine the aforementioned association. RESULTS: Substituting animal protein with plant protein had significant beneficial association with WC (OR: –4.28; 95% CI: –8.51, –0.62; Ptrend = 0.047) and LDL/HDL (OR: –0.26; 95% CI: –0.48, –0.05; Ptrend = 0.018). CONCLUSION: In elderly men, substituting animal protein with plant protein had favorable association with some of cardiovascular risk factors including WC and LDL/HDL but there was no significant association for inflammatory biomarkers.

Sex-specific relationships of inflammatory biomarkers with blood pressure in older adults.

Emerging evidence indicates an association between blood pressure and inflammation, yet this relationship remains unclear in older adults, despite the elevated prevalence of hypertension. We investigated the association between blood pressure, high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and white blood cell (WBC) count in a cohort of 3571 older adults aged 65 and above, and 587 middle-aged participants (55-59years old). In women aged 65 and above, the relationship between inflammatory markers and blood pressure was consistent, with hs-CRP and WBC emerging as predictors of high blood pressure. For hs-CRP, the adjusted odds ratio (OR) was 1.5 (95% CI, 1.07 to 2.10, P = 0.02), and for WBC, the adjusted OR was 1.41 (95% CI, 1.02 to 1.94, P = 0.04), comparing the highest to the lowest quartiles. In men, only the WBC count was significantly associated with an increased OR for high BP (adjusted OR 1.49, 95% CI, 1.09 to 2.02, P = 0.01) across quartiles. Across the entire study population, in a fully adjusted model, all inflammatory markers were modestly associated with blood pressure levels, while the effect of being over 65years was the most significant predictor of high blood pressure (OR 1.84, 95% CI, 1.50 to 2.25, P < 0.001). The link between key inflammation markers and blood pressure in older adults varies by sex and biomarker type and may differ from the relationship observed in younger individuals. These relationships are likely to be affected by factors linked to age.

Joint association of TyG index and high sensitivity C-reactive protein with cardiovascular disease: a national cohort study

BackgroundBoth the triglyceride-glucose (TyG) index, as a surrogate marker of insulin resistance, and systemic inflammation are predictors of cardiovascular diseases; however, little is known about the coexposures and relative contributions of TyG index and inflammation to cardiovascular diseases. Using the nationally representative data from the China Health and Retirement Longitudinal Study (CHARLS), we conducted longitudinal analyses to evaluate the joint and mutual associations of the TyG index and high-sensitivity C-reactive protein (hsCRP) with cardiovascular events in middle-aged and older Chinese population.MethodsThis study comprised 8 658 participants aged at least 45 years from the CHARLS 2011 who are free of cardiovascular diseases at baseline. The TyG index was calculated as Ln [fasting triglyceride (mg/dL) × fasting glucose (mg/dL)/2]. Cardiovascular events were defined as the presence of physician-diagnosed heart disease and/or stroke followed until 2018.We performed adjusted Cox proportional hazards regression and mediation analyses.ResultsThe mean age of the participants was 58.6 ± 9.0 years, and 3988 (46.1%) were females. During a maximum follow-up of 7.0 years, 2606 (30.1%) people developed cardiovascular diseases, including 2012 (23.2%) cases of heart diseases and 848 (9.8%) cases of stroke. Compared with people with a lower TyG index (< 8.6 [median level]) and hsCRP < 1 mg/L, those concurrently with a higher TyG and hsCRP had the highest risk of overall cardiovascular disease (adjusted hazard ratio [aHR], 1.300; 95% CI 1.155–1.462), coronary heart disease (aHR, 1.294; 95% CI 1.130–1.481) and stroke (aHR, 1.333; 95% CI 1.093–1.628), which were predominant among those aged 70 years or below. High hsCRP significantly mediated 13.4% of the association between the TyG index and cardiovascular disease, while TyG simultaneously mediated 7.9% of the association between hsCRP and cardiovascular risk.ConclusionsThe findings highlight the coexposure effects and mutual mediation between the TyG index and hsCRP on cardiovascular diseases. Joint assessments of the TyG index and hsCRP should be underlined for the residual risk stratification and primary prevention of cardiovascular diseases, especially for middle-aged adults.

The ketogenic diet and MetSyn in Parkinson’s disease – Symptoms, biomarkers, depression and anxiety: A case study

The use of therapeutic carbohydrate restriction (TCR) in the form of a ketogenic diet (KD) in neurodegenerative disorders such as Parkinson’s disease (PD) is increasing as an alternative treatment for primary and secondary symptoms. There exists a gap in the literature on symptoms of PD in the setting of metabolic syndrome (MetSyn) and possible comorbid impact on symptoms, biomarkers of health, cardiac risk, depression and anxiety. This case report documents a 24-week KD intervention for a 53-year-old man with multiple comorbid diagnoses, PD (Hoehn-Yahr stage IIa) with a history of morbid obesity with increased waist circumference, prediabetes, hyperinsulinaemia and significantly impaired mobility with chronic back pain, anxiety disorder and depression. Baseline cardiac risk ratios (CRR = triglycerides/HDL) were calculated and compared. The KD approach involved a well-formulated, ketogenic diet (fats 70%; protein 25%; carbohydrates 5% according to total daily energy intake for 24 weeks). Baseline, 12-week and 24-week biomarkers and scores on scales were compared. Clinically significant results were found when baseline biomarker results and scales were compared with 12-week results. Positive trends were seen for all variables at 24 weeks. Improvements in health biomarkers, including HbA1C, high sensitivity C-reactive protein (hs-CRP), triglycerides, fasting insulin, weight loss, waist circumference and cardiac risk were observed at 12 and 24 weeks. Some improvements in scores on an anxiety scale were seen. Based on our findings, KD is safe and effective for improving health biomarkers and symptoms of MetSyn, depression, anxiety and symptoms of PD. Future clinical trial studies for more generalisable results are needed.

Noninvasive cardiac-specific biomarkers for the diagnosis and prevention of vascular stenosis in cardiovascular disorder.

The most frequent lesion in the blood vessels feeding the myocardium is vascular stenosis, a condition that develops slowly but can prove to be deadly in a long run. Non-invasive biomarkers could play a significant role in timely diagnosis, detection and management for vascular stenosis events associated with cardiovascular disorders. The study aimed to investigate high sensitivity troponin I (hs-TnI), cardiac troponin I (c-TnI) and high sensitivity C-reactive protein (hs-CRP) that may be used solely or in combination in detecting the extent of vascular stenosis in CVD patients. 274 patients with dyspnea/orthopnea complaints visiting the cardiologists were enrolled in this study. Angiographic study was conducted on the enrolled patients to examine the extent of stenosis in the five prominent vessels (LDA, LCX, PDA/PLV, RCA, and OM) connected to the myocardium. Samples from all the cases suspected to be having coronary artery stenosis were collected, and subjected to biochemical evaluation of certain cardiac inflammatory biomarkers (c-TnI, hsTn-I and hs-CRP) to check their sensitivity with the level of vascular stenosis. The extent of mild and culprit stenosis was detected during angiographic examination and the same was reported in the form significant (≥50% stenosis in the vessels) and non-significant (<50% stenosis in the vessels) Carotid Stenosis. Ethical Clearance for the study was provided by Dr. Ram Manohar Lohia Institute of Medical Sciences Institutional Ethical Committee. Informed consent was obtained from all the participants enrolled in the study. We observed that 85% of the total population enrolled in this study was suffering from hypertension followed by 62.40% detected with sporadic episodes of chest pain. Most of the subjects (42% of the total population) had stenosis in their LAD followed by 38% who had stenosis in their RCA. Almost 23% patients were reported to have stenosis in their LCX followed by OM (18% patients), PDA/PLV (13%) and only 10% patients had blockage problem in their diagonal. 24% of the subjects were found to have stenosis in a single vessel and hence were categorized in the Single Vessel Disease (SVD) group while 76% were having stenosis in two or more than two arteries (Multiple Vessel Disease). hs-TnI level was found to be correlated with the levels of stenosis and was higher in the MVD group as compared to the SVD group. hs-TnI could be used as a novel marker as it shows prominence in detecting the level of stenosis quite earlier as compared to c-TnI which gets detected only after a long duration in the CVD patients admitted for angiography. hs- CRP gets readily detected as inflammation marker in these patients and hence could be used in combination with hs-TnI to detect the risk of developing coronary artery disease.

Porphyromonas gingivalis Infection is Associated with Increased Vascular Inflammation in Patients with and Without Coronary Artery Disease

Vascular inflammation is a critical measure of risk for major adverse cardiac events in patients with and without known coronary artery disease. It is recognized that patients with poor oral hygiene tend to have an increased prevalence of coronary artery disease and myocardial infarction. Porphyromonas gingivalis (PG) is the keystone pathogen leading to periodontal disease. Despite evidence suggesting a link between active PG infection and coronary artery disease, there is limited data investigating whether PG can contribute to increased markers of vascular inflammation in patients with coronary artery disease. In this study, we studied 112 consecutive patients who presented at a community preventive cardiology clinic who consented to be assessed for the presence of PG. Subjects were enrolled in a mouth along assessment with measures of vascular inflammation, which was part of their routine clinical care. The average age of patients was 70.4 ± 8.5 years with 48.6% of the patients positive for PG and 20.5% with a history of coronary artery disease (CAD). The distribution of PG positivity was 48.3% and 34.8% in patients without and with a history of CAD, respectively. Patients with CAD have significantly greater levels of high sensitivity C-reactive protein (hsCRP_ (1.3 ± 0.3 vs. 3.2 ± 1.1 mg/dL, p = 0.04) and MPO (245.1 ± 19.4 vs. 371.4 ± 39.1 pmol/L, p = 0.003). Patients without a history of CAD, only Myeloperoxidase (MPO) was significantly increased. Statin use was significantly greater in those patients with a history of CAD. Interestingly, statin use tended to be greater in PG+ patients (71% vs. 62%) regardless of CAD status. The data from this early study demonstrate a link between active PG infection and increase in markers of vascular inflammation, especially in patients with established CAD. The findings suggest PG as a marker of cardiovascular risk, especially in patients with residual inflammatory risk.

The association between depressive symptoms and high-sensitivity C-reactive protein: Is body mass index a moderator?

ObjectiveDepression and obesity are highly comorbid conditions with shared biological mechanisms. It remains unclear how depressive symptoms and body mass index (BMI) interact in relation to inflammation. This cross-sectional study investigated the independent associations of depressive symptoms and BMI with high sensitivity C-reactive protein (hs-CRP), as well as the moderating role of BMI on the depressive symptoms-hs-CRP association. MethodsParticipants (n = 8827) from the 2015–2018 National Health and Nutrition Examination Surveys were aged ≥20 with a BMI ≥18.5 kg/m2, completed the Depression Screener, and had hs-CRP data. Multivariable linear regression was used to analyze hs-CRP in relation to depressive symptoms and BMI. An interaction term was included to examine whether the depressive symptoms-hs-CRP relationship differs depending on BMI. ResultsThere was a slight, albeit non-significant, increase in hs-CRP levels with each one-point increase in depressive symptoms (aCoef.Estm. = 0.01, 95% CI = −0.05, 0.06, p = 0.754). Participants with overweight (aCoef.Estm. = 1.07, 95% CI = 0.61, 1.53, p < 0.001) or obese (aCoef.Estm. = 3.51, 95% CI = 3.04, 3.98, p < 0.001) BMIs had higher mean hs-CRP levels than those with a healthy BMI. There were no significant interactions between depressive symptoms and overweight (aCoef.Estm. = 0.04, 95% CI = −0.04, 0.13, p = 0.278) or obese (aCoef.Estm. = 0.11, 95% CI = −0.01, 0.22, p = 0.066) BMI indicating a lack of difference in the depressive symptoms-hs-CRP association across participants in the healthy versus overweight and obese ranges. ConclusionsThis study suggests that BMI might not act as a moderator in the association between depressive symptoms and hs-CRP. Results should be replicated in larger samples. Further research is warranted to understand underlying mechanisms.

High Sensitivity C-Reactive Protein as an Independent Risk Factor for Preeclampsia with Severe Features

Background: One of the most dangerous complications of pregnancy and a major contributor to maternal and perinatal morbidity and death is preeclampsia. The goal of the current study was to measure the level of inflammation in severe preeclampsia by measuring serum high-sensitive C-reactive protein (hs-CRP) and establishing a relationship between hs-CRP and blood pressure. Objective: The aim of this study is to evaluate the impact high sensitivity C-reactive protein as an independent risk factor for preeclampsia with severe features. Methods: The cross-sectional study was carried out in the Department of Obstetrics &amp; Gynecology of Dhaka Medical College Hospital, Dhaka, from July 2022 to June 2023. A total of 200 patients were enrolled and analyzed in this study. The questionnaire was pretested, corrected and finalized. Data were collected by face-to-face interview and analyzed by appropriate computer based programmed software Statistical Package for the Social Sciences (SPSS), version 24. Results: In this study, majority 95 (47.5%) of the patients were in 21 – 30 years age group and 60 (30.00%) patients were in &gt;30 years age group, Mean±SD of age was 27.12 ± 4.12 years. Most of the patients 150 (75.00%) were housewife and 50 (25.00%) patients were service holder. About 55 (27.5) patients were completed their graduation, 50 (25.00%) were completed higher secondary and 20 (10) were illiterate, most of the patients 145 (72.5%) came from rural area and 55(27.5) patients came from urban area. Nullipara was found in 75 (37.5%) patients and multigravida was found in most of the patients 110 (55.00%). Antenatal care was found irregular in 105 (52.5%) patients. Preterm pregnancy was found in majority 145 (72.5%) of the patients. Systolic and diastolic blood pressure were found higher and hsCRP was also found higher in PE with severe features. APGAR score was found less in 65 (32.5%) neonate at birth and APGAR score was found good in 55 (27.5%) neonate at 5 minutes. Average birth weight was found in 75 (37.5%) neonates, LBW was found in 85 (42.5) neonates and very LBW was found in 40 (20.00%) neonates of PE with severe features patients. Intrauterine growth retardation and prematurity were found in 75 (37.5%) and 20 (10.00%) neonates, admission to NICU was needed for 45 (22.5%) neonates, birth asphyxia was found in 15 (7.5%) neonates and stillbirth was occured in 35 (17.5%) cases. Conclusion: An exaggerated systemic inflammatory response, which may produce reactive oxygen species and worsen endothelial dysfunction, is present in preeclampsia. Clinical signs of hypertension and proteinuria in preeclampsia result from this. Preeclampsia-related maternal mortality and systemic complications may be reduced with early identification. hsCRP may therefore be a valuable gauge of preeclampsia severity.

Brief Report: Relationship Between Adiposity and Biomarkers of Aging and Frailty Among Adults Aging With HIV.

This study examined the relationships among adiposity, handgrip, physical function, inflammation (ie, senescence-associated secretory phenotype chemokines as biomarkers of aging and frailty), and sex hormones in aging people with HIV. This cross-sectional exploratory study included 150 people with HIV aged ≥40 years (67.3% of participants were male). Our measures included (1) body mass index and waist circumference as measures of adiposity; (2) handgrip as a measure of muscle strength; (3) short physical performance battery as a measure of physical function; (4) interleukin-6, tumor necrosis factor alpha receptor II, high sensitivity C-reactive protein, C-X-C motif chemokine 10, and C-X3-C motif chemokine ligand 1 also known as fractalkine as senescence-associated secretory phenotype chemokines; and (5) free testosterone, estradiol, sex hormone-binding globulin, and dehydroepiandrosterone as sex hormones. Quantile regression analyses were used to identify relationships among inflammatory markers and hormones with age, adiposity, handgrip, and physical function. Overall, 74% (n = 111) of participants were classified as overweight or obese and 53.3% (n = 80) presented with abdominal obesity. After controlling for age and sex, body mass index was positively associated with estradiol (β = 0.043, P < 0.01), and waist circumference was positively associated with high sensitivity C-reactive protein (β = 2.151, P < 0.01). After controlling for sex, age was positively associated with C-X-C motif chemokine 10 (β = 0.024, P = 0.03) and tumor necrosis factor alpha receptor II (β = 2.205, P = 0.01). After controlling for age and sex, short physical performance battery was negatively associated with dehydroepiandrosterone (β = -0.004, P = 0.01); no statistically significant associations were observed for handgrip. Adiposity levels and aging were associated with inflammation (ie, C-X-C motif chemokine 10, tumor necrosis factor alpha receptor II, and high sensitivity C-reactive protein) among people with HIV aged 40 years and older.

PULMONARY ARTERIAL HYPERTENSION ASSOCIATED WITH CONGENITAL HEART DISEASE: RATIONALE FOR MANAGEMENT ALGORITHM BASED ON A LITERATURE REVIEW

The substantial progress achieved in cardiology and paediatric cardiac surgery has led to a considerable increase of life expectancy of patients with congenital heart disease (CHD), and at the same time to growing number of adult patients developing pulmonary arterial hypertension (PAH) associated with congenital heart defects. Nowadays guidelines were developed and updated for PAH, but no expert recommendations exist for effective management of PAH associated with CHD. Thus, it is important to develop an algorithm for managing these patients, based on international standards and a comprehensive understanding of prognostic markers of worsening the course of pulmonary arterial hypertension (PAH), considering local cardiac tertiary hospitals' capabilities.&#x0D; The aim. To highlight the pathophysiology and clinical characteristics of PAH-CHD patients, identify prognostic markers for its onset and progression, and develop a management algorithm for patients.&#x0D; Results. The article presents the pathophysiology of PAH-CHD, the mechanisms of right ventricle adaptation to pressure overload, which determine the functional abilities of patients and prognosis, PAH formation, and progression after defects correction. The accurate identification of stages in PAH-CHD (volume overload, mixed, stage of pulmonary vascular disease) is essential for the timely determination of surgical intervention, selecting conservative treatment strategies, and predicting the outcomes of surgical defect correction. The type of defect, its size, and the volume of blood flow through the defect influence the onset and progression of PH-CHD. We review the pathophysiology and clinical features of PAH-CHD, as well as the reasons for the late diagnosis of heart failure at the stage of severe decompensation and irreversible remodelling of the lung vessels when diuretic therapy is not effective enough and inotropic support, circulatory mechanical support and heart / lung complex transplantation are required. The necessity of developing new scales for stratifying the risk of PAH-CHD is justified considering the particularities of the disease course and cardiac hemodynamic in different anatomical types of the defects. Based on this literature review, at the Municipal Enterprise «Dnipropetrovsk Regional Clinical Center for Diagnostics and Treatment» of the Dnipropetrovsk Regional Council» the algorithm for managing patients with PAH-CHD was devised and implemented into clinical practice.&#x0D; Conclusions. PAH is a common complication of CHD. The prevalence of PAH-CHD is substantial and it can manifest and progress even in patients with previously corrected heart defects. To effectively manage patients with PAH-CHD, an algorithm has been devised and implemented in clinical practice. It includes factors that have demonstrated associations with poor prognosis which are more than two hospitalizations for HF in the last year, pulmonary vascular resistance (PVR) (or index of PVR), mean pressure in the pulmonary artery, pulmonary capillary wedge pressure, left ventricular ejection fraction, heart failure with a reduced ejection fraction, right ventricle heart failure, NYHA FC, high risk of atrial fibrillation or flutter, 6-minute walking test distance, NTproBNP, highly sensitive C-reactive protein, B-lines on lung ultrasound, glomerular filtration rate, haemoglobin, platelet count, sodium, Model for End-Stage Liver Disease scale.

The relationship between a series of inflammatory markers on the risk of heart failure in different gender groups: Analysis from NHANES 2015-2018.

A better understanding of the level-grade inflammation for the development and worsening of heart failure (HF) in different gender groups is an unmet need. We performed an updated analysis on the impact of a series of systemic inflammation markers on HF. This compensatory cross-sectional study enrolled participants from the National Health and Nutrition Examination Survey (NHANES) 2015-2018. HF was based on the self-reported questions. Univariate and multivariate logistic regression were used to investigate the association between systemic immune-inflammation index (SII), high sensitivity C-reactive protein (hs-CRP), lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and HF. For patients of different genders, P for trend was used to analyze potential linear trend relationships and the restricted cubic splines (RCS) were used to describe non-linear relationships. The additive interaction was evaluated by the relative excess risk due to interaction (RERI), attributable proportion (AP), and the synergy index (SI). The multiplicative interaction was evaluated by odds ratio (OR) and 95% confidence interval (CI) of product-term. A total of 5,830 participants from the NHANES database were divided into two groups: the HF group (n = 210) and the non-HF group (n = 5620). After gender stratification, hs-CRP (OR: 1.01, 95% CI: 1.00-1.03), SII (OR: 1.00, 95% CI: 1.00-1.01), NLR (OR: 1.22, 95% CI: 1.11-1.35) and LMR (OR: 0.79, 95% CI: 0.65-0.93) were independent meaningful factors for HF in males, there was no non-linear relationship between the three factors (SII, NLR, hs-CRP, all P for non-linear > 0.05) and the prevalence of HF, but we detected a non-linear relationship between LMR and the prevalence of HF in males (P for non-linear < 0.05). An additive interaction of hs-CRP and NLR on the risk of HF in males (RERI (OR): 0.67, 95% CI: 0.12-1.34; AP (OR): 0.14, 95% CI: 0.02-0.24; SI (OR): 1.22, 95% CI: 1.03-1.44). In summary, hs-CRP, NLR, and LMR are superior meaningful markers for HF in males. SII may be a meaningful systemic inflammation warning marker for HF, which needs to be discriminated against with caution. Only detected a non-linear relationship between LMR and the prevalence of HF in males. NLR and hs-CRP may have an additive interaction in the prevalence of male HF patients. The outcome compensated for previous studies that still needed more studies for validation.

Association of FoxP3&lt;sup&gt;+&lt;/sup&gt; T regulatory lymphocytes with epicardial adipose tissue thickness in patients with coronary heart disease

Background. Increase ofthe epicardial adipose tissue (EAT) thickness isassociated with development of inflammation and cardiovascular complications, however, there is no data on the relationship between EAT thickening and the number of immunosuppressive regulatory T lymphocytes.The aim. To study the number of circulating T regulatory lymphocytes and nuclear translocation ofthe FoxP3 transcription factor in patients with stable coronary heart disease (CHD) depending on the epicardial adipose tissue thickness.Materials and methods. We examined 30 patients with chronic stable CHD. The EAT thickness was measured by echocardiography. Patients were divided into groups depending on the presence and absence of EAT thickening above 5 mm (groups 1 and 2, respectively). Imaging flow cytometry was used to determine the number of T regulatory lymphocytes and the level of FoxP3 nuclear translocation. The concentration of cytokines and high sensitivity C-reactive protein (hsCRP) was determined using enzyme-linked immunosorbent assay in blood serum.Results. Anthropometric indicators of obesity and the severity of atherosclerosis were comparable between groups. In group 2, there was an increase in low-density lipoprotein cholesterol concentration (p = 0.043), ratio of low-density lipoprotein cholesterol tohigh-density lipoprotein cholesterol (p = 0.017) and the concentration ofhsCRP (p = 0.044) andIL-1β (p = 0.005), adecrease in the number and relative count of Tregulatory lymphocytes (p = 0.020 andp = 0.026, respectively), aswellas thenumber of cells withFoxP3 nuclear translocation (p = 0.018) compared togroup1. According tomultiple logistic regression, the concentration ofhsCRP, IL-1β and T regulatory lymphocytes relative count in total were the predictors of EAT thickening (accuracy 80 %; sensitivity 75 %; specificity 84,6 %; AUC = 0.89).Conclusions. Thickening of epicardial adipose tissue inpatients withcoronary heart disease is associated with a decrease in the number of T regulatory lymphocytes andFoxP3 nuclear translocation inthem in presence of comparable anthropometric parameters of obesity and the severity of coronary atherosclerosis.

Abstract 3435: History of breastfeeding in relation to circulating inflammatory biomarkers

Abstract Background: History of breastfeeding has been associated with reduced risk of various chronic diseases in which chronic inflammation is involved in disease etiology, including cardiovascular disease, type II diabetes, breast cancer, and ovarian cancer. However, few studies have investigated the long-term impact of breastfeeding on systemic inflammation. Thus, we aimed to examine the associations between breastfeeding history and circulating inflammatory biomarkers at midlife. Methods: We conducted a cross-sectional analysis including 3,448 parous women with plasma inflammatory biomarkers in the Nurses’ Health Study and Nurses’ Health Study II. We examined self-reported history of ever breastfeeding (ever vs. never) and lifetime total duration of breastfeeding (never, &amp;lt; 6 months, 7-11 months, 12+ months) prior to the time of blood draw. We calculated the geometric means of eight inflammatory biomarkers [i.e., high sensitivity C-reactive protein (hsCRP), interleukin-6 (IL6], sIL6Rα, IL8, IL10, sIL2-receptor-α(Rα), soluble tumor necrosis factor α receptor 2 (sTNFR2), B-cell activating factor (BAFF), C-X-C motif chemokine ligand 13 (CXCL13)] by self-reported history of breastfeeding status adjusted for age, body mass index (BMI), smoking status, duration of oral contraceptive use, parity, proinflammatory diet, analgesic use, menopausal status, and cohort. Tests for trend were calculated using the median value of each lifetime breastfeeding duration category and modeling as a continuous variable. We also conducted stratified analyses by menopausal status and BMI (&amp;lt; 25kg/m2 vs. ≥ 25kg/m2) at blood draw. Results: Overall, we did not observe statistically significant differences in circulating inflammatory biomarker levels by history of breastfeeding among parous women. When stratifying by menopausal status at blood draw, total breastfeeding duration was inversely associated with sTNFR2 levels among premenopausal women (P-trend = 0.03) but not among postmenopausal women. Plasma IL8 levels were suggestively inversely associated with breastfeeding duration among postmenopausal women (P-trend = 0.07) but not among premenopausal women. Among women with BMI ≥ 25 kg/m2, plasma BAFF levels were lower in parous women who ever breastfed compared to those who never breastfed [1382.5 (95%CI = 1242.0 - 1539.0) pg/ml vs. 1611.9 (95%CI = 1424.9 - 1823.4) pg/ml; p = 0.03], and suggestively inversely associated with total breastfeeding duration (p-trend = 0.07) but no statistically significant association was observed in women with BMI &amp;lt; 25kg/m2. IL10 was inversely associated with total breastfeeding duration among women with BMI ≥25 kg/m2 (P-trend = 0.007), but not in women with BMI &amp;lt; 25kg/m2. Conclusion: Overall, history of breastfeeding was not associated with inflammatory biomarkers at mid-life, however the association may vary by menopausal status and BMI.

Dietary intake of vitamin D in adult outpatients with different degrees of obesity coming from an urban community

The aim of the present study was to investigate in-depth the dietary intake of vitamin D of subjects with different BMI in relation to serum vitamin D status. The survey covered 264 individuals, aged 19 to 60 years. Vitamin D deficiency was found in 33.3% of the participants and 40.2% showed evidence of insufficient vitamin D intake. It was established that the daily average dietary intake of vitamin D among the whole group of subjects was 6.6 μg/day (women – 5.6 μg/day, men – 10.4 μg/day). We found significant correlations between daily average dietary intake of vitamin D and weight, % body fat, fat mass, visceral fat (in women), muscle and fat-free mass, and height-adjusted indices: fat mass index and fat-free mass index, total body water and some metabolic variables (basal insulin and high sensitivity C-reactive protein). The survey revealed that the dietary intake of vitamin D of the respondents was insufficient.

Evaluation of Interleukin 4, High Sensitivity C-Reactive Protein and Activity of Alanine Transaminase Among Cooks in Nnewi

Soot arises from burning wood, oils, tires, and other hydrocarbon or organic compounds. Soot is widespread and has a massive detrimental effect on human health, climate, and air quality. The serum levels of Interleukin 4, High sensitivity C-reactive protein, and alanine transaminase activity were evaluated. This cross–sectional study recruited 90 participants consisting of 45 participants exposed to soot (test group) and 45 participants not exposed to soot (control group). The Faculty of Health Sciences and Technology Ethics Committee at Nnamdi Azikiwe University granted ethical approval, and participants’ informed consent was acquired. Interleukin 4 and high sensitivity C-reactive protein levels were determined using the Sandwich ELISA method while the activity of alanine transaminase was determined using the spectrophotometric method. Questionnaires were used to obtain the socio-demographic data of the participants and the body mass index (BMI) was calculated using weight (kg)/height2 (m2). Independent t-test and Pearson’s correlation coefficient were used for statistical analysis and significance was set at p&lt;0.05. The results showed that the mean serum activity of alanine transaminase (9.30 ± 0.28) was significantly lower in the participants exposed to soot compared with the control (9.48 ± 0.37) (p&lt;0.05). However, there was no significant difference in the mean serum levels of Interleukin 4 and high sensitivity C-reactive protein of participants exposed to soot compared with the control (p&gt;0.05). Hence, exposure to soot through the use of firewood did not predispose cooks to systemic inflammation, or cardiovascular and hepatic dysfunctions.&#x0D; Keywords: Soot, alanine transaminase, Interleukin 4, high sensitivity C-reactive protein, inflammation

Lack of Immune Resilience Negatively Affects Physical Resilience: Results From the InCHIANTI Follow-Up Study.

There is consistent evidence that immune response declines with aging, with wide interindividual variability and a still unclear relationship with the development of frailty. To address this question, we assessed the role of immune resilience (capacity to restore immune functions), operationalized as the neutrophil-to-lymphocytes ratio (NL-ratio) and monocytes-to-lymphocytes ratio (ML-ratio), in the pathway that from robust status shifts to pre-frailty and frailty, and finally to death. The InCHIANTI study enrolled representative samples from the registry lists of 2 towns in Tuscany, Italy. Baseline data were collected in 1998, with follow-up visits every 3 years. The 1453 participants enrolled were assessed and followed for lifestyle, clinical condition, physical performance, clinical, and physiological measures. For the purpose of this analysis, we used only 1022 subjects aged 65 or older at baseline. Participants in the 3 highest deciles of distribution for NL-ratio (>2.44) were more likely to experience a transition from robust to pre-frail, and to overt frailty status. Moreover, NL-ratio (tenth decile > 3.53) and ML-ratio (tenth decile > 2.02) were both predictors of mortality. These results were independent of chronological age, sex, comorbidities, and chronic low-grade inflammation assessed by high sensitivity C-reactive protein measurement. The 2 leucocytes-derived ratios, NL-ratio and ML-ratio, represent markers of immune resilience and predict changes in physical resilience and mortality. These biomarkers are inexpensive because they are based on data routinely collected in clinical practice and can be used to assess the risk of frailty progression and mortality.

Estimation of Pro-Inflammatory Markers In Night Shift Healthcare Workers And Identify Risk Factors Associated With It

Shift labor, with hours outside of the regular diurnal work cycle, is used to facilitate round-the-clock emergency healthcare services. This impacts the circadian rhythm, which can potentially activate the pro-inflammatory responses of the immune system. This study aimed to find out the levels of pro-inflammatory markers in night shift healthcare workers and find risk factors associated with their increase. 303 participants (doctors, nurses, technicians, health care aids) were recruited with 169 participants nightshift and 134 dayshift workers. Pro-inflammatory markers Highly Sensitive C-Reactive Protein (hsCRP) and Total Leukocyte Count (TLC)] were estimated. Factors were compared by t test, Wilcoxon Rank Sum test and Chi square test. Risk factors for hsCRP elevation were identified by logistic regression analysis. Pro-inflammatory markers like hsCRP and TLC were significantly increased in night shift health workers in comparison to the day shift workers (hsCRP 0.30± 0.33 mg/dl vs 0.10± 0.09 mg/dl, TLC 8181.06± 1181.53 /cu mm vs 7473.80± 1018.81 /cu mm) respectively. Multivariate logistic regression analysis showed night shift work (OR 48.20 95% CI (4.99-465.61), age (OR 1.13 95% CI (1.01-1.26)) and BMI (OR 1.18 95% CI (1.06-1.32)) as independent predictors of elevated hsCRP after adjusting for other risk factors. Hence, night-shift work is an independent risk factor for a rise in pro-inflammatory markers. These findings might aid health care workers and policymakers strategize methods to tackle the challenges through providing support programs, counselling sessions to avoid ailments and deliver health services in a better way.
