Assessment of Risk Factors for Non-communicable Diseases among Young Adults in Kerala, India

Abstract Objectives: To estimate risk factors for non-communicable diseases (NCDs) amongst young adults and to determine the association between NCDs and various risk factors amongst young adults. Materials and Methods: This study was done amongst 150 young adults of Kerala. The data were collected by conducting direct interviews with the use of pre-designed semi-structured questionnaire. Anthropometric and biochemical parameters such as total cholesterol, low-density lipids were collected and analysed using standard methods. Results: Amongst the 150 study participants, 104 (69.4%) were girls and 46 (30.6%) were boys. Amongst these 68 (45.3%) had body mass index (BMI) >23. The study shows that 25.3% and 27.3% of participants had high diastolic blood pressure (DBP) and systolic blood pressure (SBP), respectively. Males had high BP, whereas abdominal adiposity was more amongst females. Physical activity amongst participants was very low. There is a positive correlation between BMI and SBP (r = 0.28, odds ratio [OR] =3.9); BMI and DBP (r = 0.24, OR = 2.9) and waist circumference (WC) with SBP (r = 0.25,); WC and DBP (r = 0.283). The increased BMI (crude odds ratio-3.979; 95% confidence interval-1.490–10.625) has got association with hypertension. Conclusions: There is a high prevalence of risk factors of NCDs amongst the young adult population of Kerala. The findings emphasise the need for interventions to reduce these risk factors amongst these young adults by life cycle approach.

Relation Between Exposure to Tobacco Smoke Assessed by Serum Cotinine Concentration and Questionnaire Method, and Serum Renalase Concentration-the Importance of the Coexistence of Arterial Hypertension and Other Cardiovascular Diseases.

Exposure to tobacco smoke (ETS) is one of the main risk factors for cardiovascular disease (CVD). Renalase is a protein that may play a role in the pathogenesis of CVD. The aim of the study was to assess the relationship between ETS and serum renalase concentration. A group of 109 patients was recruited for this study (49.7 ± 14.7years). In accordance with the questionnaire, patients were divided into the following subgroups: subgroup A- declaring themselves active smokers (n = 36), subgroup B- declaring themselves non-smokers and exposed to environmental tobacco smoke (n = 35), subgroup C- declaring themselves non-smokers and not exposed to environmental tobacco smoke (n = 38). The same patients were divided based on cotinine concentration into the following subgroups: subgroup D- active smokers (n = 42), subgroup E- non-smokers exposed to environmental tobacco smoke (n = 66), and subgroup F- non-smokers not exposed to environmental tobacco smoke (n = 1). Serum cotinine concentration and serum renalase concentration were measured using ELISA tests. Serum renalase concentration was statistically significantly higher in subgroup C than in subgroups A and B and in subgroup E and F than in D. There was a negative correlation between serum cotinine concentration and serum renalase concentration (r = -0.41, p < 0.05). Regression analysis showed that higher BMI, higher diastolic blood pressure, coronary artery disease and higher serum cotinine concentration are independent risk factors of lower serum renalase concentration. The questionnaire method of assessing exposure to tobacco smoke was characterized by high sensitivity, but only moderate specificity, especially in terms of assessing environmental exposure to tobacco smoke. In summary, the study showed an independent relationship between exposure to tobacco smoke and lower serum renalase concentration.

Dyslipidemia in children with chronic kidney disease-findings from the Cardiovascular Comorbidity in Children with Chronic Kidney Disease (4C) study.

Dyslipidemia is an important and modifiable risk factor for CVD in children with CKD. In a cross-sectional study of baseline serum lipid levels in a large prospective cohort study of children with stage 3-5 (predialysis) CKD, frequencies of abnormal lipid levels and types of dyslipidemia were analyzed in the entire cohort and in subpopulations defined by fasting status or by the presence of nephrotic range proteinuria. Associated clinical and laboratory characteristics were determined by multivariable linear regression analysis. A total of 681 patients aged 12.2 ± 3.3years with a mean eGFR of 26.9 ± 11.6ml/min/1.73 m2 were included. Kidney diagnosis was classified as CAKUT in 69%, glomerulopathy in 8.4%, and other disorders in 22.6% of patients. Nephrotic range proteinuria (defined by a urinary albumin/creatinine ratio > 1.1g/g) was present in 26.9%. Dyslipidemia was found in 71.8%, and high triglyceride (TG) levels were the most common abnormality (54.7%). Fasting status (38.9%) had no effect on dyslipidemia status. Except for a significant increase in TG in more advanced CKD, lipid levels and frequencies of dyslipidemia were not significantly different between CKD stages. Hypertriglyceridemia was associated with younger age, lower eGFR, shorter duration of CKD, higher body mass index (BMI-SDS), lower serum albumin, and higher diastolic blood pressure. Dyslipidemia involving all lipid fractions, but mainly TG, is present in the majority of patients with CKD irrespective of CKD stage or fasting status and is significantly associated with other cardiovascular risk factors.

Multidimensional phenotyping to distinguish among distinct obstructive sleep apnea, chronic obstructive pulmonary disease, and overlap syndrome phenotypes

Objective/backgroundChronic obstructive pulmonary disease (COPD), obstructive sleep apnea (OSA) and their comorbid association called Overlap Syndrome (OS) are frequent chronic diseases with high individual and societal burdens. Precise descriptions of the respective symptoms, comorbidities, and medications associated with these three conditions are lacking. We used a multidimensional phenotyping approach to identify relevant phenotypes characterizing these 3 disorders. Patients/methods308 patients with OSA, COPD and OS were prospectively assessed using a combination of body shape measurements and multidimensional questionnaires evaluating sleep, fatigue, depression and respiratory symptoms. Comorbidities and medications were confirmed by physicians. Patients made home blood pressure self-measurements using a connected wearable device to identify undiagnosed or uncontrolled hypertension. ResultsThree distinct relevant phenotypes were identified. OSA patients were round in shape with a balanced waist-to-hip ratio, frequent witnessed apneas, nocturia, daytime sleepiness, depression, and high diastolic blood pressure. COPD patients had a thinner body shape with a high waist-to-hip ratio, complained mainly of fatigue, and exhibited a higher resting heart rate. OS patients were round in shape with a balanced waist-to-hip ratio, reported little sleepiness and depression, but had impaired sleep and the highest rate of cardio-metabolic comorbidities. Diminished fitness-to-drive was most apparent in patients with OSA and OS. Home blood pressure measurements identified undiagnosed hypertension in 80 % of patients and in nearly 80 % of those with hypertension it was uncontrolled by their current medications. ConclusionsOur systematic multidimensional phenotyping approach identified distinct body shapes, symptoms, and comorbidity profiles among patients with OSA, COPD, and OS.

Effects of Heavy Alcohol Use on Nighttime Blood Pressure, Sleep Quality, and Urine Catecholamines

Heavy alcohol drinking habits contribute to the development of hypertension; this is partly due to overactivation of the sympathetic nervous system and the increased release of catecholamines. Recently, heavy alcohol drinking has been linked to poor sleep quality, but the underlying mechanisms remain unclear. We postulated that long-term frequent heavy alcohol use could increase catecholamine levels and cause blood pressure dysregulation at night, altogether influencing sleep quality. Therefore, the purpose of this study is to test the following hypothesis that compared to non-heavy drinkers, heavy drinkers have a higher level of nighttime catecholamines, a higher levels of nighttime blood pressure, and poorer sleep quality. A total of 44 men and postmenopausal women non-smokers, free of major clinical diseases, were included in this study. Heavy drinkers were defined as those having a dried blood spot phosphatidylethanol (PEth, a biomarker to detect heavy alcohol drinking) level ≥ 20 ng/mL. Participants wore an ambulatory blood pressure monitor for 24 hours and catecholamines were measured from urine samples collected in the same 24-hour period. Sleep quality was measured by using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. There were 21 heavy drinkers (mean±SEM for age: 58±1 and BMI: 26.2±0.7 kg/m2) and 23 non-heavy drinkers (age: 58±1 and BMI: 27.5±0.8 kg/m2; P≥0.3 vs. heavy drinkers). Compared to non-heavy drinkers, heavy drinkers had a higher nighttime systolic blood pressure (SBP), higher diastolic blood pressure (DBP), and a lower SBP dipping ratio (heavy drinkers vs. non-heavy drinkers for nighttime SBP: 118±3 vs. 109±2 mmHg, P=0.02; nighttime DBP: 70±2 vs. 65±2 mmHg, P=0.04; and SBP dipping ratio: 10.6±1.4% vs. 14.5±1.6%, P=0.04). No differences were found in nighttime urine catecholamines between heavy drinkers and non-heavy drinkers (P≥0.3). A total of 13 participants had a PSQI score higher than 5, indicating poor sleep quality; however, PSQI scores were similar between heavy and non-heavy drinkers (P=0.8). These findings indicate that heavy drinkers had a higher nighttime blood pressure and are consistent with the observation that heavy drinking is associated with an increased risk of hypertension in mid-life adults. Interestingly, the increase in nighttime blood pressure does not appear to be related to catecholamines and sleep quality in apparently healthy mid-life adults does not appear to be influenced by heavy drinking habits.

Gender Differences in Prevalence and Associated Factors of Dyslipidemia in Initial-Treatment and Drug-Naïve Schizophrenia Patients.

Dyslipidemia is frequently comorbid with schizophrenia (SCZ), and both conditions often demonstrate significant gender differences in their clinical features. This study specifically focuses on investigating the prevalence of dyslipidemia and the factors that contribute to it in initial-treatment and drug-naïve (ITDN) SCZ patients, specifically focusing on gender differences. A total of 224 male ITDN SCZ patients and 424 female ITDN SCZ patients were included in this study. Socio-demographic and general clinical data of the patients were collected, and routine biochemical parameters, such as lipid levels, fasting blood glucose, thyroid function, renal function, and blood cell counts, were measured. Patients were also assessed for psychopathology and disease severity using the Positive and Negative Syndrome Scale (PANSS) and the Clinical Global Impression Scale - Severity of Illness (CGI-SI), respectively. In addition, a lipids score was calculated for assessing the severity of dyslipidemia. The study revealed that the prevalence of dyslipidemia in male patients was 34.02% (83/224), whereas 33.25% (141/424) in females, indicating no statistically significant difference (χ2 = 0.04, p = 0.841). For males, the risk factors for dyslipidemia were high education levels and diastolic blood pressure (DBP), while red blood cell count (RBC) as a protective factor. Additionally, DBP was identified as a risk factor for dyslipidemia score. In females, systolic blood pressure (SBP) was identified as a risk factor for dyslipidemia, while being married and creatinine (CRE) levels were found to be protective factors. Moreover, SBP was revealed as a risk factor for dyslipidemia score. No significant gender differences were observed in the prevalence of dyslipidemia among the ITDN SCZ patients. However, notable gender differences were identified in the factors influencing dyslipidemia and its severity within this group. These findings suggest the necessity of implementing gender-specific interventions to address the potential risk factors associated with dyslipidemia.

The Assessment of Knowledge Regarding Hypertension and Treatment Adherence

Background: Hypertension is a leading global health challenge due to its substantial role in increasing the risk of cardiovascular and renal diseases. Despite its prevalence, there remains a significant gap in the general population's knowledge about hypertension management and the adherence to treatment protocols. Objective: This study aimed to assess the level of knowledge regarding hypertension and the adherence to treatment among patients diagnosed with the condition in a tertiary care setting in Lahore, Pakistan. Methods: A descriptive cross-sectional study was conducted at Jinnah Hospital, Lahore. The study utilized convenient sampling to recruit 135 patients diagnosed with hypertension. Data were collected using a structured questionnaire adapted from Morisky et al. (2008), which included sections on demographic data, knowledge about hypertension, and treatment adherence. The reliability of the scales was confirmed with a Cronbach’s alpha of 0.997 for the knowledge scale and 0.983 for the adherence scale. Data analysis was performed using descriptive statistics and frequency distributions in SPSS version 25. Results: The majority of participants were aged between 31-40 years (75.8%), with a balanced gender distribution (53.3% male, 46.7% female). Educational levels varied, with the majority holding matric qualifications (46.7%). Knowledge about hypertension was moderate, with 45.9% correctly identifying the implications of high diastolic or systolic blood pressure. However, substantial misconceptions persisted regarding the necessity of lifestyle changes alongside medication. Treatment adherence was moderately low, with 45.9% of participants frequently forgetting to take their medication, and a significant portion deliberately skipping doses. Conclusion: The study highlighted a moderate understanding of hypertension and a corresponding moderate to low adherence to treatment protocols among patients. These findings underscore the urgent need for targeted educational interventions to enhance knowledge and improve adherence, ultimately aiming to reduce the burden of hypertension-related complications.

Relationship Between Dietary Intakes and Elevated Diastolic Blood Pressure Among Children: A Cross-Sectional Study Using Wearable Devices.

Elevating systolic blood pressure (SBP) and diastolic blood pressure (DBP) independently influences clinical outcomes and adverse cardiovascular events. Blood pressure can be affected by modifiable (such as diets and physical activities) and non-modifiable factors (such as age and gender). Elevated blood pressure (EBP or formerly prehypertension) during childhood is associated with hypertension incidence in later adulthood. This cross- sectional study investigated modifiable risk factors for blood pressure among children (aged 3-12). We employed wearable devices to monitor the blood pressure of 45 preschool and primary school children and analyze this data with secondary blood pressure data of their parents from electronic medical records. EBP phenotypes in children (offspring) were not related to their parent's blood pressure phenotypes (P = 0.15 and 0.19 for SBP). Consumption of high saturated fat (P = 0.032), copper (P = 0.026), and vitamin B12 (P = 0.032) was associated with a significant increase in DBP. Daily sodium intakes between normal and DBP hypertensive groups were not significantly different (P = 0.75). This study indicates that dietary intakes of high saturated fat, copper, and vitamin B12, but not parental blood pressure statuses, determine high diastolic blood pressure among children regardless of daily sodium intake. Early dietary consumption behavioral adaptation should be considered to prevent further hypertension in adulthood.

Association between maternal cardiometabolic markers and fetal growth in non-complicated pregnancies: a secondary analysis of the PRINCESA cohort.

The objective of this study was to evaluate the association of maternal cardiometabolic markers trajectories (glucose, triglycerides (TG), total cholesterol, systolic blood pressure (SBP) and diastolic blood pressure (DBP)) with estimated fetal weight trajectories and birth weight in Mexican pregnant women without medical complications. Cardiometabolic marker trajectories were characterized using group-based trajectory models. Mixed-effect and linear regression models were estimated to assess the association of maternal trajectories with estimated fetal weight and birth weight. The final sample comprised 606 mother-child dyads. Two trajectory groups of maternal cardiometabolic risk indicators during pregnancy were identified (high and low). Fetuses from women with higher values of TG had higher weight gain during pregnancy ( = 24.00g; 95%CI: 12.9, 35.3), were heavier at the sixth month ( =48.24g; 95%CI: 7.2, 89.7) and had higher birth weight ( = 89.08g; 95%CI: 20.8, 157.4) than fetuses in the low values trajectory. Fetuses from mothers with high SBP and DBP had less weight in the sixth month of pregnancy ( = - 42.4g; 95%CI: - 82.7, - 2.1 and = - 50.35g; 95%CI: - 94.2, - 6.4), and a higher DBP trajectory was associated with lower birth weight ( = - 101.48g; 95%CI: - 176.5, - 26.4). In conclusion, a longitudinal exposition to high values of TG and BP was associated with potentially adverse effects on fetal growth. These findings support the potential modulation of children's phenotype by maternal cardiometabolic conditions in pregnancies without medical complications.

Parental recovered acute kidney injury causes prenatal renal dysfunction and fetal growth restriction with sexually dimorphic implications for adult offspring.

Introduction: Acute kidney injury (AKI) is rapidly increasing in global incidence and a healthcare burden. Prior maternal AKI diagnosis correlates with later pregnancy complications. As pregnancy influences developmental programming, we hypothesized that recovered parental AKI results in poor pregnancy outcomes, impaired fetal growth, and adult offspring disease. Methods: Using a well-characterized model of rhabdomyolysis-induced acute kidney injury (RIAKI), a form of AKI commonly observed in young people, we confirmed functional renal recovery by assessing glomerular filtration rate (GFR) 2weeks following RIAKI. We bred sham and recovered RIAKI sires and dams in timed, matched matings for gestational day (GD) 16.5 and offspring (birth-12weeks, 6months) study. Results: Despite a normal GFR pre-pregnancy, recovered RIAKI dams at GD16.5 had impaired renal function, resulting in reduced fetoplacental ratios and offspring survival. Pregnant RIAKI dams also had albuminuria and less renal megalin in the proximal tubule brush border than shams, with renal subcapsular fibrosis and higher diastolic blood pressure. Growth-restricted offspring had a reduced GFR as older adults, with evidence of metabolic inefficiency in male offspring; this correlated with reduced renal AngII levels in female offspring from recovered RIAKI pairings. However, the blood pressures of 6-month-old offspring were unaffected by parental RIAKI. Conclusions: Our mouse model demonstrated a causal relationship among RIAKI, gestational risk, and developmental programming of the adult-onset offspring GFR and metabolic dysregulation despite parental recovery.

Abstract P215: Activity Behaviors and Cardiometabolic Health Outcomes in People Living With HIV

Introduction: Physical activity (PA) and sedentary behavior (SB) are independently associated with cardiometabolic health; data on activity behaviors and cardiometabolic health among people living with HIV (PWH) are limited. Hypothesis: Activity behaviors would differ by age and that not meeting PA Guidelines would be associated with an increased risk of cardiometabolic diseases among PWH. Methods: Using NHANES 2007-08 through 2017-18, PWH (n=125; age 44.3 yrs) were characterized as emerging (18-29 yrs), early (30-44 yrs) and middle (45-59 yrs) adulthood. Achieving Guidelines (≥150 min/wk) was derived from self-reported PA across three domains. SB was reported as time spent sitting. Chronic conditions were high cholesterol, obesity, hypertension, and chronic kidney disease. Prevalence estimates of joint high SB (≥8 h/day) and inactivity (&lt;10 min/wk) were calculated, and regression models were used to estimate differences in behaviors by age and investigate the association between achieving Guidelines and chronic conditions. Results: PWH reported 395.8 min/day of SB with 37.5% spending over 8 h/day sitting. There was no significant difference in SB across lifestage. A total of 67.2% achieved Guidelines although 14% were jointly inactive and highly sedentary. Compared with early adult PWH, middle adult PWH spent more time performing transport-related PA (β= 102.7 min/wk, p =0.009) and less time performing leisure-time PA (β= -211 min/wk, p =0.044) ( Figure ). Compared with PWH meeting Guidelines , those that did not meet Guidelines had higher diastolic blood pressure (β= 6.1 mmHg [CI: 2.6, 9.6]) and higher odds of obesity (OR=2.5[CI: 1.0, 6.4]). Conclusions: Domain-specific differences occurred in transportation and leisure time PA among PWH - a high-risk group for cardiovascular disease. Not meeting the Guidelines resulted in greater odds of obesity and higher diastolic blood pressure. Future research should incorporate device-based measures of movement to understand its relation to chronic disease in PWH.

Association of Blood Pressure With Brain White Matter Microstructural Integrity Assessed With MRI Diffusion Tensor Imaging in Healthy Young Adults.

High blood pressure (BP) in middle-aged and older adults is associated with a brain white matter (WM) microstructural abnormality. However, little evidence is available in healthy young adults. We investigated the associations between high BP and WM microstructural integrity in young adults. This study included 1015 healthy young adults (542 women, 22-37 years) from the Human Connectome Project. Brachial systolic and diastolic BP were measured using a semiautomatic or manual sphygmomanometer. Diffusion-weighted magnetic resonance imaging was acquired to obtain diffusion tensor imaging metrics of free water (FW) content, FW-corrected WM fractional anisotropy, axial diffusivity, radial diffusivity, and mean diffusivity. Using whole-brain voxel-wise linear regression models and ANCOVA, we examined associations of BP and hypertension stage with diffusion tensor imaging metrics after adjusting for age, sex, education, body mass index, smoking status, alcohol consumption history, and differences in the b value used for diffusion magnetic resonance imaging. Systolic and diastolic BP of the sample (mean±SD) were 122.8±13.0 and 76.0±9.9 mm Hg, respectively. Associations of BP with diffusion tensor imaging metrics revealed regional heterogeneity for FW-corrected fractional anisotropy. High BP and high hypertension stage were associated with higher FW and lower FW-corrected axial diffusivity, FW-corrected radial diffusivity, and FW-corrected mean diffusivity. Moreover, associations of high diastolic BP and hypertension stage with high FW were found only in men not in women. High BP in young adults is associated with altered brain WM microstructural integrity, suggesting that high BP may have damaging effects on brain WM microstructural integrity in early adulthood, particularly in men.

Associations between arterial health and sexual function in women aged 60-64 years.

Female sexual dysfunction is very common, but its determinants remain under-investigated. Vasculogenic impairments are suggested to be related to female sexual dysfunction, but previous literature regarding the association is scarce. This study aims to study the association between arterial health and female sexual function in women in their 60s. The sample for this cross-sectional study comprised 117 women (aged 60-64 years) who participated in the Finnish Retirement and Aging study. Arterial health was measured according to the participants' pulse wave velocity, ankle-brachial index, blood pressure, and pulse pressure. Sexual function was measured using the Female Sexual Function Index, which resulted in a total score and six sub-scores. Associations were examined using multivariable regression analyses, which were adjusted for age, relationship happiness, systemic menopausal hormone therapy and/or local estrogen, smoking, alcohol risk use, body mass index, and depressive symptoms. Higher diastolic blood pressure was associated with a higher total Female Sexual Function Index score (β = 0.24, 95% confidence interval [CI] 0.07-0.41) and with higher desire (β = 0.02, 95% CI 0.01-0.04), arousal (β = 0.04, 95% CI 0.01-0.08), lubrication (β = 0.04, 95% CI 0.002-0.08), satisfaction (β = 0.03, 95% CI 0.003-0.05), and pain (β = 0.06, 95% CI 0.02-0.10) sub-scores. Also, higher ankle-brachial index was associated with higher satisfaction sub-score (β = 2.10, 95% CI 0.44-3.73) and lower pulse pressure was associated with higher orgasm sub-score (β = 0.03, 95% CI 0.0002-0.06). Other associations between ankle-brachial index and Female Sexual Function Index scores were statistically insignificant, but considering the magnitude the findings may imply clinical significance. Systolic blood pressure and pulse wave velocity were not associated with sexual function. This study suggested a plausible association between higher diastolic blood pressure and female sexual function, but considering clinical significance our findings suggest an association between higher ankle-brachial index and good sexual function in women in their 60s.

A new sports garment with elastomeric technology optimizes physiological, mechanical, and psychological acute responses to pushing upper-limb resistance exercises.

This study aimed to compare the mechanical (lifting velocity and maximum number of repetitions), physiological (muscular activation, lactate, heart rate, and blood pressure), and psychological (rating of perceived exertion) responses to upper-body pushing exercises performed wearing a sports elastomeric garment or a placebo garment. Nineteen physically active young adults randomly completed two training sessions that differed only in the sports garment used (elastomeric technology or placebo). In each session, subjects performed one set of seated shoulder presses and another set of push-ups until muscular failure. The dependent variables were measured immediately after finishing the set of each exercise. Compared to the placebo garment, the elastomeric garment allowed participants to obtain greater muscular activation in the pectoralis major (push-ups: p = 0.04, d = 0.49; seated shoulder press: p < 0.01, d = 0.64), triceps brachialis (push-ups, p < 0.01, d = 0.77; seated shoulder press: p < 0.01, d = 0.65), and anterior deltoid (push-ups: p < 0.01, d = 0.72; seated shoulder press: p < 0.01, d = 0.83) muscles. Similarly, participants performed more repetitions (push-ups: p < 0.01; d = 0.94; seated shoulder press: p = 0.03, d = 0.23), with higher movement velocity (all p ≤ 0.04, all d ≥ 0.47), and lower perceived exertion in the first repetition (push-ups: p < 0.01, d = 0.61; seated shoulder press: p = 0.05; d = 0.76) wearing the elastomeric garment compared to placebo. There were no between-garment differences in most cardiovascular variables (all p ≥ 0.10). Higher diastolic blood pressure was only found after the seated shoulder press wearing the elastomeric garment compared to the placebo (p = 0.04; d = 0.49). Finally, significantly lower blood lactate levels were achieved in the push-ups performed wearing the elastomeric garment (p < 0.01; d = 0.91), but no significant differences were observed in the seated shoulder press (p = 0.08). Overall, the findings of this study suggest that elastomeric technology integrated into a sports garment provides an ergogenic effect on mechanical, physiological, and psychological variables during the execution of pushing upper-limb resistance exercises.

Differences in the clinical and hormonal presentation of patients with familial and sporadic primary aldosteronism.

To compare the clinical and hormonal characteristics of patients with familial hyperaldosteronism (FH) and sporadic primary aldosteronism (PA). A systematic review of the literature was performed for the identification of FH patients. The SPAIN-ALDO registry cohort of patients with no suspicion of FH was chosen as the comparator group (sporadic group). A total of 360 FH (246 FH type I, 73 type II, 29 type III, and 12 type IV) cases and 830 sporadic PA patients were included. Patients with FH-I were younger than sporadic cases, and women were more commonly affected (P = 0.003). In addition, the plasma aldosterone concentration (PAC) was lower, plasma renin activity (PRA) higher, and hypokalemia (P < 0.001) less frequent than in sporadic cases. Except for a younger age (P < 0.001) and higher diastolic blood pressure (P = 0.006), the clinical and hormonal profiles of FH-II and sporadic cases were similar. FH-III had a distinct phenotype, with higher PAC and higher frequency of hypokalemia (P < 0.001), and presented 45 years before sporadic cases. Nevertheless, the clinical and hormonal phenotypes of FH-IV and sporadic cases were similar, with the former being younger and having lower serum potassium levels. In addition to being younger and having a family history of PA, FH-I and III share other typical characteristics. In this regard, FH-I is characterized by a low prevalence of hypokalemia and FH-III by a severe aldosterone excess causing hypokalemia in more than 85% of patients. The clinical and hormonal phenotype of type II and IV is similar to the sporadic cases.

Household food insecurity is associated with greater autonomic dysfunction testing score in Latinos with type 2 diabetes.

We examined household food insecurity (HFI) and autonomic nervous system (ANS) function in a subset of low-income Latinos with type 2 diabetes with data from a stress management trial. InclusionLatino or Hispanic, Spanish speaking, age less than 18 years, ambulatory status, type 2 diabetes more than 6 months, A1c less than 7.0%. ExclusionPain or dysfunction in hands (e.g., arthritis) precluding handgrip testing; medical or psychiatric instability. HFI was assessed with the 6-item U.S. household food security survey module; with responses to > = 1 question considered HFI. An ANS dysfunction index was calculated from xix autonomic function tests which were scored 0 = normal or 1 = abnormal based on normative cutoffs and then summed. Autonomic function tests were: 1) 24-hour heart rate variability as reflected in standard deviation of the normal-to-normal (SDNN) heart rate acquired with 3-channel, 7-lead ambulatory electrocardiogram (Holter) monitors; 2) difference between the highest diastolic blood pressure (DBP) during sustained handgrip and the average DBP at rest; 3) difference between baseline supine and the minimal BP after standing up; and, from 24-hour urine specimens 4) cortisol, 5) normetanephrine, and, 6) metanephrine. Thirty-five individuals participated, 23 (65.7%) of them were women, age mean = 61.6 (standard deviation = 11.2) years, HbA1c mean = 8.5% (standard deviation = 1.6) and 20 participants (57.1%) used insulin. Twenty-two participants (62.9%) reported HFI and 25 (71.4%) had one or more abnormal ANS measure. Independent t-tests showed that participants with HFI had a higher ANS dysfunction index (mean = 1.5, standard deviation = 0.9) than patients who were food secure (mean = 0.7, standard deviation = 0.8), p = 0.02. Controlling for financial strain did not change significance. Total ANS index was not related to glycemia, insulin use or other socioeconomic indicators. In this sample, HFI was associated with ANS dysfunction. Policies to improve food access and affordability may benefit health outcomes for Latinos with diabetes.

Association between vitamin D status and cardiometabolic risk factors in adults with type 2 diabetes in Shenzhen, China.

Evidence of vitamin D status and cardiometabolic health in adults with type 2 diabetes mellitus (T2DM) is still limited. This study aimed to investigate the association between vitamin D status and cardiometabolic risk factors among adults with T2DM in Shenzhen, China. This cross-sectional study included 164 adults (aged ≥18 years) with T2DM who were hospitalized at Peking University Shenzhen Hospital from March 1, 2023, to May 31, 2023. Serum 25-hydroxyvitamin D [25(OH)D] concentration, the active marker of vitamin D, and three major cardiometabolic risk factors including blood pressure (BP), glucose metabolism-related indicators, and blood lipid profiles were collected. Vitamin D deficiency (VDD) was defined as 25(OH)D < 20 ng/mL. Correlation, Regression, and Logistic analysis were applied to verify the association among serum 25(OH)D concentration, VDD, and 11 cardiometabolic risk factors. Median 25(OH)D concentration was 21.78 [interquartile range (IQR)=17.51-28.05] ng/mL. The prevalence of VDD was 40.24%. Serum 25(OH)D concentration was significantly negatively correlated with diastolic BP (DBP) and glycated hemoglobin A1c (HbA1c) rather than systolic BP, plasma glucose, plasma C-peptide, and blood lipid profiles among adults with T2DM in both correlation and linear regression analysis. Furthermore, the adjusted odd ratio for poor DBP control (≥90 mmHg) of T2DM patients with VDD was 3.164 (95% confidence interval=1.303, 7.683; P=0.011) compared to those without VDD. In China, VDD was highly prevalent among adults with T2DM and associated with greater cardiovascular risk factors, especially with increased chances of uncontrolled DBP. These findings suggest that vitamin D levels should be monitored in T2DM patients, especially those with high DBP.

Identification of a gene network driving the attenuated response to lipopolysaccharide of monocytes from hypertensive coronary artery disease patients.

The impact of cardiovascular disease (CVD) risk factors, encompassing various biological determinants and unhealthy lifestyles, on the functional dynamics of circulating monocytes-a pivotal cell type in CVD pathophysiology remains elusive. In this study, we aimed to elucidate the influence of CVD risk factors on monocyte transcriptional responses to an infectious stimulus. We conducted a comparative analysis of monocyte gene expression profiles from the CTMM - CIRCULATING CELLS Cohort of coronary artery disease (CAD) patients, at baseline and after lipopolysaccharide (LPS) stimulation. Gene co-expression analysis was used to identify gene modules and their correlations with CVD risk factors, while pivotal transcription factors controlling the hub genes in these modules were identified by regulatory network analyses. The identified gene module was subjected to a drug repurposing screen, utilizing the LINCS L1000 database. Monocyte responsiveness to LPS showed a highly significant, negative correlation with blood pressure levels (ρ< -0.4; P<10-80). We identified a ZNF12/ZBTB43-driven gene module closely linked to diastolic blood pressure, suggesting that monocyte responses to infectious stimuli, such as LPS, are attenuated in CAD patients with elevated diastolic blood pressure. This attenuation appears associated with a dampening of the LPS-induced suppression of oxidative phosphorylation. Finally, we identified the serine-threonine inhibitor MW-STK33-97 as a drug candidate capable of reversing this aberrant LPS response. Monocyte responses to infectious stimuli may be hampered in CAD patients with high diastolic blood pressure and this attenuated inflammatory response may be reversed by the serine-threonine inhibitor MW-STK33-97. Whether the identified gene module is a mere indicator of, or causal factor in diastolic blood pressure and the associated dampened LPS responses remains to be determined.

Incorporating longitudinal history of risk factors into atherosclerotic cardiovascular disease risk prediction using deep learning

It is increasingly clear that longitudinal risk factor levels and trajectories are related to risk for atherosclerotic cardiovascular disease (ASCVD) above and beyond single measures. Currently used in clinical care, the Pooled Cohort Equations (PCE) are based on regression methods that predict ASCVD risk based on cross-sectional risk factor levels. Deep learning (DL) models have been developed to incorporate longitudinal data for risk prediction but its benefit for ASCVD risk prediction relative to the traditional Pooled Cohort Equations (PCE) remain unknown. Our study included 15,565 participants from four cardiovascular disease cohorts free of baseline ASCVD who were followed for adjudicated ASCVD. Ten-year ASCVD risk was calculated in the training set using our benchmark, the PCE, and a longitudinal DL model, Dynamic-DeepHit. Predictors included those incorporated in the PCE: sex, race, age, total cholesterol, high density lipid cholesterol, systolic and diastolic blood pressure, diabetes, hypertension treatment and smoking. The discrimination and calibration performance of the two models were evaluated in an overall hold-out testing dataset. Of the 15,565 participants in our dataset, 2170 (13.9%) developed ASCVD. The performance of the longitudinal DL model that incorporated 8 years of longitudinal risk factor data improved upon that of the PCE [AUROC: 0.815 (CI 0.782–0.844) vs 0.792 (CI 0.760–0.825)] and the net reclassification index was 0.385. The brier score for the DL model was 0.0514 compared with 0.0542 in the PCE. Incorporating longitudinal risk factors in ASCVD risk prediction using DL can improve model discrimination and calibration.

Early Prognostic Instrumental and Laboratory Biomarkers in Post-MI.

Post-myocardial infarction (MI) changes have been frequently reported in the literature and are associated with determining the prognosis. The aim of this study is to find a prognosis marker for the favorability of determination of the medium-term outcomes in patients with acute MI. MI patients' prognosis is poorly understood and requires further elaboration. A single center, cross-sectional cohort study involved 211 patients' medical history with acute MI, for the period 2014-2019, had been evaluated retrospectively for 76 parameters. The data was collected from the Republic Rehabilitation Mordovian Hospital. The described measurement units were used in the local laboratories to describe the values. The descriptive values were expressed in the mean average and standard deviation. For statistical analysis, descriptive statistics, t-test independent by groups and dependent by numerical variables for repeated analysis for the same patients, multinomial logistic regression, Pearson's correlation coefficient, ROC analysis, and for clarification purposes, diagrams and bar figures were used. For performing the statistical analysis, the SPSS program, version 28 was used. Descriptive statistics showed a proportion of men to females 7:3. The mean age of the MI patients was 61.50 years (Std. Dev. ± 10.68), and the mean height of the sample was 171.00 cm (Std. Dev. ± 7.20). The mean body weight of the sample is 83.62 kg (Std. Dev. ± 12.35), and the body mass index (BMI) is 29.02 kg/m2 (Std. Dev. ± 5.07). The total hospitalization days are 14.79 (Std. Dev. ± 3.41). The mean heart rate (HR) beat per minute (bpm) was 79.03 (Std. Dev. ± 15.63), and the mean blood pressure was 138.53/84.09 mmHg (Std. Dev. ± 28.66/12.79). On the complete blood count (CBC), the mean level of the hemoglobin (Hb) 136.33 g/l (Std. Dev. ± 15.29), the mean level of the leukocytes (WBC) 8.76 /μl (Std. Dev. ± 2.77), the mean level of the red blood cells (RBC) 4.55 /μl (Std. Dev. ± 0.52), the mean level of the relative value of the lymphocytes 24.46 % (Std. Dev. ± 9.015), and the mean level of the thrombocytes 207.87 /μl (Std. Dev. ± 64.035). The mean erythrocytes segmentation rate (ESR) is 18.99 mm/hr (Std. Dev. ± 12.16). The regression analysis demonstrated that the dependent variable, complication, in particular, pericarditis, and the independent factor, concomitant disease, in particular, chronic heart failure, has a significant regression coefficient of 29.101 at p <0.05. Furthermore, the dependent variable, complication, in particular, pneumonitis, and the independent factor, concomitant disease, particularly, arrhythmia, have a significant regression coefficient of 21.937 at p <0.05. An elevated level of CPK-MB/LDH/Troponin I is linked to the development of arrhythmia. Patients with other medical conditions experience high diastolic blood pressure and an enlargement of the right ventricle. The early complication observed after MI is the formation of a left ventricular aneurysm. Complications arise due to low levels of potassium and calcium. Chronic Kidney Disease (CKD) contributes to the End-Diastolic Size (EDS) of the Left Ventricle (LV), Troponin I, and creatine phosphokinase-MB (CPK-MB). Advanced CKD patients have a hypertrophic left ventricle and persistently elevated post-myocardial Infarction (MI) cardiac biomarkers (CPKMB/ LDH/Troponin I) due to impaired kidney detoxification. Therefore, prolonged elevation of MI biomarkers can be an indicative of severe MI or kidney function impairment due to the chronic mild elevation in the MI biomarkers. Pericarditis development is related to the pre-existence of chronic heart failure. Moreover, pneumonitis development is related to the pre-existence of arrhythmia. Others: Hypertensive patients do not exhibit a significant increase in calcium levels, indicating that it is not a reliable biomarker in this patient population. Additionally, gender plays a crucial role in the development of ischemic heart disease, including myocardial infarction.
