RESUMO
Introdução: As dislipidemias estão entre os fatores de riscos mais importantes para o desenvolvimento de doenças cardiovasculares (DCV), além de estarem relacionadas a outras patologias que predispõem às DCV. Em função da elevada prevalência e da incidência de complicações associadas à cronicidade da doença, as dislipidemias representam elevados custos ao setor da saúde e da previdência social. Diante disso, ressalta-se a importância do Sistema Único de Saúde, representado pela Atenção Primária à Saúde (APS), em prover práticas de prevenção, diagnóstico e acompanhamento dos pacientes dislipidêmicos, a fim de desonerar o sistema financeiro e promover o envelhecimento saudável. Objetivo: Descrever a prevalência de perfil lipídico alterado entre os idosos. Além disso, pretendeu-se caracterizar a amostra quanto aos aspectos sociodemográficos, de saúde e de comportamento, bem como analisar os fatores associados à distribuição do perfil lipídico alterado e às características da amostra. Métodos: Estudo transversal com dados secundários, obtidos de agosto de 2021 a julho de 2022, tendo como população pacientes idosos em acompanhamento na APS do município de Marau (RS). Todos os dados foram coletados dos prontuários eletrônicos da rede de APS e, após dupla digitação e validação dos dados, a amostra foi caracterizada por meio de estatística descritiva. Foi calculada a prevalência de perfil lipídico alterado com intervalo de confiança de 95% (IC95%) e foi verificada sua distribuição conforme as variáveis de exposição, empregando-se o teste do χ2 e admitindo-se erro tipo I de 5%. Resultados: A prevalência de dislipidemia proporcional entre os sexos foi maior no feminino (33%). A cor de pele predominante foi a branca (76,7%). Cerca de 20% dos pacientes apresentavam colesterol total, colesterol HDL-c e triglicerídeos alterados, enquanto cerca de 15% apresentavam o colesterol HDL-c anormal. Constatou-se que os pacientes dislipidêmicos apresentam mais diabetes e hipertensão em relação aos não dislipidêmicos, ocorrendo a sinergia de fatores de risco para as DCV. Conclusões: A caracterização exercida neste estudo serve de base científica para a compreensão da realidade local e, também, para o direcionamento de políticas públicas na atenção primária que atuem de forma efetiva na prevenção e no controle das dislipidemias e demais fatores de risco cardiovascular.
Introduction: Dyslipidemias are among the most important risk factors for the development of cardiovascular diseases (CVD), in addition to being related to other pathologies that predispose to CVD. Because of the high prevalence and incidence of complications associated with the chronicity of the disease, dyslipidemias represent high costs for the health and social security sector. This highlights the importance of the Unified Health System, represented by primary health care (PHC), in providing prevention, diagnosis and follow-up practices for dyslipidemic patients to relieve the financial system and promote healthy aging. Objective: The study aimed to describe the prevalence of altered lipid profile among older people. In addition, we sought to characterize the sample in terms of sociodemographic, health and behavioral aspects, as well as to analyze the factors associated with the distribution of the altered lipid profile and the characteristics of the sample. Methods: We conducted a cross-sectional study with secondary data, from August 2021 to July 2022, with older patients being followed up at the PHC in the city of Marau (RS) as the study population. All data were collected from the electronic medical records of the PHC network, and after double-typing and validation, the sample was characterized using descriptive statistics. The prevalence of altered lipid profile was determined with a 95% confidence interval (95%CI), and its distribution was verified according to the exposure variables, using the chi-square test and a type I error of 5%. Results: The prevalence of proportional dyslipidemia between sexes was higher in females (33%). The predominant skin color was white (76.7%). About 20% of the patients had altered total cholesterol, HDL-C and triglycerides, while about 15% had abnormal HDL-C. It was found that more dyslipidemic patients had diabetes and hypertension than non-dyslipidemic patients, with a synergy of risk factors for CVD. Conclusions: The characterization carried out in this study serves as a scientific basis for understanding the local reality and also for directing public policies in PHC that act effectively in the prevention and control of dyslipidemia and other cardiovascular risk factors.

A Randomized Controlled Trial involving 158 Brazilian medical and nursing students assessed one of three conditions over an 8-week period: 1) a circuit training protocol (CTG); 2) a yoga protocol (YG); or 3) no intervention (CG). The objective was to evaluate the effectiveness of circuit training and yoga protocols in reducing perceived mental stress and examining their effects on serum cortisol levels, as well as on traditional cardiovascular risk factors (CRFs), during an academic semester. Mental stress was measured using self-reported stress questionnaires. For the CTG, comparisons of pre- vs. post-intervention data indicated a reduction in self-reported stress levels on a Brazilian scale (p < 0.001) and an international scale (p < 0.05). Regarding CRFs, there was a reduction in waist circumference (WC) (p < 0.05), systolic blood pressure (SBP) (p < 0.05), and heart rate (HR) (p < 0.001). No changes were observed in diastolic blood pressure (DBP) (p = 0.211) and serum cortisol (SC) (p = 0.423). In the YG, pre- vs. post-intervention data indicated a reduction in self-reported stress levels on the ISSL (p < 0.001), in both resistance and exhaustion stress levels on the PSS scale (p < 0.001), and in SC levels (p < 0.001), WC (p < 0.05), and SBP (p < 0.05); however, HR and DBP did not change (p = 0.168 and p = 0.07, respectively) in this group. No changes were noted in any measures in the CG. The intervention protocols demonstrated that both CTG and YG can positively impact mental or biochemical stress responses, as well as CRFs.

The byproduct of Salvia hispanica (chia) seed oil extraction by cold pressing, also known as expeller, possesses a high nutritional value. It is rich in proteins, fibers, minerals, and has a residual oil content of 7-11%, which is rich in omega 3 linolenic acid (ALA). However, this byproduct has been historically undervalued. Thus, the aim of current work was to study the effects of consuming of a rich in chia expeller diet on a rabbit model of metabolically unhealthy normal weight to validate their use as a functional food. Rabbits were fed different diets for a period of 6 weeks: a standard diet (CD), a high-fat diet (HFD), a rich in expeller CD (Exp-CD) and a rich in expeller HFD (Exp-HFD). The Exp-HFD attenuated the rise in basal glucose, TyG index, triglycerides, cholesterol and non-HDL cholesterol induced by the HFD. Both rich in expeller diets reduced mean arterial blood pressure (MAP) and increase liver and fat ALA levels compared to their respective controls. Furthermore, the angiotensin converting enzyme (ACE) activity was lower in the lungs of animals fed on rich in expeller diets compared to their respective controls. In vitro studies showed that ALA inhibited ACE activity. The evaluation of vascular reactivity revealed that rich in expeller diets improved angiotensin II affinity and reduced contractile response to noradrenaline. In conclusion, the consumption of rich in expeller diets showed beneficial effects in preventing cardiovascular risk factors such as insulin resistance, dyslipidemia and MAP. Therefore, its use as functional ingredient holds significant promise.

BACKGROUND: Most cardiovascular (CV) events stem from modifiable risk factors, but it remains uncertain whether their impact on mortality has decreased in recent years as a result of treatment, particularly in low- and middle-income countries. We evaluated the temporal trends in the population attributable fraction (PAF) of modifiable risk factors to CV mortality in patients undergoing myocardial perfusion imaging (MPI) for suspected coronary artery disease in a large city in Brazil. METHODS: The cohort comprised 25,127 patients without established CV disease undergoing MPI in a referral center in Curitiba, Brazil, from 2010 to 2018. Baseline demographic, clinical and risk factors were prospectively collected. Modifiable risk factors encompassed hypertension, dyslipidemia, diabetes mellitus, sedentary lifestyle, obesity, and smoking. The primary outcome was CV death occurring up to 4 years of follow-up. The PAF of each risk factor was calculated for each triennium using multivariable Cox proportional regression models, adjusting for age, sex and family history of premature coronary disease. RESULTS: Over 9 years, there were 1438 deaths, 444 due to CV causes. In the first triennium, sedentary lifestyle exhibited the highest PAF (49%) for CV death, followed by hypertension (17%), diabetes mellitus (8%) and smoking habit (6%). The PAF for all risk factors combined remained relatively stable thorough the triennia (2010-2012: 57% vs 2013-2015: 64% vs 2016-2018: 47%, p = NS). CONCLUSION: In this large cohort of patients referred to MPI, the PAF of modifiable CV risk factors did not diminish in the last decade, with sedentary lifestyle having the largest contribution for CV mortality. CONDENSED ABSTRACT: This study examinated temporal trends in the impact of modifiable cardiovascular (CV) risk factors on CV and overall mortality in a cohort of 25,127 patients undergoing myocardial perfusion imaging from 2010 to 2018. Sedentary behavior consistently had the greatest impact on both CV and overall mortality, followed by hypertension and diabetes. Smoking had a lesser effect, while obesity showed no independent association with the outcomes. The contributions of these modifiable CV risk factors remained stable over the study period, suggesting that interventions promoting physical activity may be essential in mitigating the burden of CV disease.

BACKGROUND: Walking/run promotes greater post-exercise hypotension (PEH) than resistance exercise (RE) which can be associated nitric oxide production. Then, we investigated if adding walking between RE increases PEH. METHODS: Thirteen hypertensive women (48 ± 1.9 years; 26.8 ± 0.3 kg/m2) performed five experimental sessions: 1-traditional RE with passive interval (PIBS); 2-RE with active interval between sets (AIBS); 3-RE with active interval between exercises (AIEX); 4-aerobic exercise (AE); 5-no exercise. Blood pressure was measured before and immediately after exercise and every 10 min of a 60-min post-exercise recovery period. Plasma nitrite (NO) and malondialdehyde (MDA) were also measured. RESULTS: AIBS, AIEX, and AE sessions promoted systolic PEH (12 ± 1.53; 16 ± 2.13; 18 ± 1.34 mmHg, respectively) and diastolic PEH (8 ± 1.38; 8 ± 0.79; 8 ± 0.58 mmHg). In AIBS, AIEX and AE sessions, significant PEH was noted at 10 or 20 min; in PIBS, PEH was significant only at 40 min. In the PIBS session, NO did not change, but presented higher values after AIBS, AIEX and AE sessions. MDA showed no changes between sessions. CONCLUSIONS: Passive or active intervals in resistance exercise promote PEH in hypertensive women. Active intervals shorten the PEH onset time as additional benefit.

The prevalence and incidence of obesity and the comorbidities linked to it are increasing worldwide. Current therapies for obesity and associated pathologies have proven to cause a broad number of adverse effects, and often, they are overpriced or not affordable for all patients. Among the alternatives currently available, natural bioactive compounds stand out. These are frequently contained in pharmaceutical presentations, nutraceutical products, supplements, or functional foods. The clinical evidence for these molecules is increasingly solid, among which epigallocatechin-3-gallate, ellagic acid, resveratrol, berberine, anthocyanins, probiotics, carotenoids, curcumin, silymarin, hydroxy citric acid, and α-lipoic acid stand out. The molecular mechanisms and signaling pathways of these molecules have been shown to interact with the endocrine, nervous, and gastroenteric systems. They can regulate the expression of multiple genes and proteins involved in starvation-satiety processes, activate the brown adipose tissue, decrease lipogenesis and inflammation, increase lipolysis, and improve insulin sensitivity. This review provides a comprehensive view of nature-based therapeutic options to address the increasing prevalence of obesity. It offers a valuable perspective for future research and subsequent clinical practice, addressing everything from the molecular, genetic, and physiological bases to the clinical study of bioactive compounds.

INTRODUCTION: Hypertension (HTN) represents the primary individual risk factor, contributing significantly to the global burden of cardiovascular diseases (CVD). In our country, epidemiological research has highlighted substantial variations in the prevalence of these risk factors across different populations. However, there is a lack of epidemiological studies assessing exclusive cardiovascular risk factors within vulnerable neighborhoods characterized by extremely limited economic resources, sociocultural challenges, and inadequate healthcare access. METHODS: A multicenter cross-sectional observational study was conducted among individuals residing in economically deprived and marginalized communities, including informal settlements and underprivileged neighborhoods. Simple random sampling of households was employed. Blood pressure measurements, anthropometric assessments, and epidemiological, economic, and sociocultural questionnaires were administered. Results encompass prevalence rates, awareness levels, and blood pressure control across diverse regions. Logistic regression was utilized to identify independent variables influencing primary outcomes. RESULTS: A total of 989 participants were analyzed. The overall prevalence of hypertension was 48.2%. About 82% had a body mass index (BMI) >25. Approximately 45.3% had less than 6 years of formal education. Independent association was established between education levels below 6 years and higher hypertension prevalence. Among hypertensive individuals, 44% were unaware of their condition, with only 17.2% achieving control, correlated with having health insurance and a higher educational background. Merely 24% were receiving combined therapy. CONCLUSION: The prevalence of hypertension within vulnerable neighborhoods is alarmingly high, surpassing rates in other social strata. Knowledge, treatment, and control levels of hypertension are suboptimal, comparable to other populations. Inadequate use of combination therapy was observed. This study underscores the urgent need for targeted interventions addressing cardiovascular risk factors in poor areas to mitigate the burden of CVD.

AIM: To assess the relationship of cardiovascular risk factors (CRFs) with carotid intima media thickness (IMT) in adolescents with a parental history of premature coronary artery disease (PCAD). METHODS: This cross-sectional study included 50 healthy adolescents, aged 14-18 years, both sexes, with a parental history of PCAD, that were compared to 50 controls without this history. Questionnaires regarding information of CRFs were applied. Blood chemistry analyses, included lipid profile, lipoprotein (a), low density lipoprotein (LDL) susceptibility to oxidation, and inflammatory cytokine levels. The IMT was evaluated by ultrasound. RESULTS: The mean age of all participants was 15.9 years. Anthropometric measurements, blood pressure, and lipid profile were similar in both groups. However, the parental history of PCAD group exhibited lower high density lipoprotein cholesterol concentrations, shorter LDL particle oxidation time, and higher lipoprotein (a) levels compared to the control group. IMT was significantly higher in adolescents with a parental history of PCAD compared to controls, (0.53 ± 0.04 mm vs 0.47 ± 0.02 mm, p = 0.001). Among adolescents with a parental history of PCAD, those with ≥ 3 CRFs had significantly higher IMT values (0.56 mm) than those with < 3 CRFs (0.52 mm) and controls (0.48 mm). Multivariable analyses identified that systolic blood pressure and parental history of PCAD explained 26.8% and 16.1% of the variation in IMT. Furthermore, body mass index, LDL-C, ApoB-100, triglycerides and lipoprotein (a) interact with blood pressure levels to explain the IMT values. CONCLUSION: Adolescents with a parental history of PCAD had higher IMT values than the control group, primary explained by systolic blood pressure and the parental inheritance. Adolescents with parental history of PCAD and ≥ 3 CRFs exhibited the highest IMT values. Notably, lipids and systolic blood pressure jointly contribute to explain IMT in these adolescents.

BACKGROUND: Life's Simple 7, a lifestyle and cardiovascular index associated with cognition, has been updated to Life's Essential 8 (LE8) to include sleep. LE8 has been related to cardiovascular outcomes but its association with cognition is unclear. METHODS: In this longitudinal analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), LE8 score was based on health behaviors (diet, physical activity, nicotine exposure, and sleep health) as well as health-related factors (body mass index, blood lipids, blood glucose, and blood pressure). Cognition was assessed in three waves, 4 years apart, using the Consortium to Establish a Registry for Alzheimer's Disease - Word List, semantic and phonemic verbal fluency, the Trail-Making Test B (TMT-B), and a global composite score. We used linear mixed-model analysis, inverse probability weighting, and interaction analysis. RESULTS: At baseline, the mean age of the study cohort was 51.4 ± 8.9 years, 56% were women, and 53% were White. Higher baseline LE8 scores were associated with slower decline in global cognition (ß = 0.001, 95% confidence interval [CI] 0.001, 0.002; p < 0.001), memory (ß = 0.001, 95% CI 0.000, 0.002; p = 0.013), verbal fluency (ß = 0.001, 95% CI 0.000, 0.002; p = 0.003), and TMT-B (ß = 0.004, 95% CI 0.003, 0.005; p < 0.001). This association was mainly driven by LE8 health factors, particularly blood glucose and blood pressure. Age, sex, and race were modifiers of the association between LE8 and global cognitive decline (p < 0.001), suggesting it was more pronounced in older, male, and Black participants. CONCLUSIONS: Higher baseline LE8 scores were associated with slower global and domain-specific cognitive decline during 8 years of follow-up, mainly due to health factors such as blood glucose and blood pressure. Sociodemographic factors were modifiers of this association.

BACKGROUND: Few studies in Latin America have examined the association between cardiovascular risk factors and cognitive impairment (CI) in a nationally representative sample. Therefore, this study aimed to estimate the prevalence of CI in a nationally representative sample of adults aged 60 years or older from Chile and to investigate the association between cardiovascular risk factors and CI. METHODS: Data from the cross-sectional 2016-2017 National Health Survey of Chile, which included 2031 adults (63.7% women) was used. Body mass index, metabolic syndrome (blood pressure, triglycerides, fasting glucose or treatment for diabetics, waist circumference, and HDL cholesterol), risk of cardiovascular disease (history and measured variables, using the Framingham risk score), tobacco use, and physical activity were measured. CI was assessed using the Mini-Mental Status Examination (MMSE). RESULTS: Overall, the prevalence of CI was 12.2% at the national level. Significant differences in CI were observed by age, education level, risk of cardiovascular disease, and smoking. High risk of cardiovascular disease was associated with higher odds of CI (OR: 2.04; 95%CI: 1.20-3.45) compared to low risk. Smoking was significantly associated with a lower likelihood of CI (OR: 0.56; 95%CI: 0.36-0.87) compared to never smoking. Body mass index, metabolic syndrome, and physical activity were not associated with CI. CONCLUSIONS: This study provided additional support for previous findings on the relationship between cognitive decline and an elevated risk of cardiovascular disease. Worse CI was associated with the group with the highest risk of cardiovascular disease, and the presence of lifestyle factors, such as obesity and physical inactivity, exacerbate this relationship, but not being a current smoker.

During the pandemic confinement, the WHO changed the term "social distancing" to "physical distancing", to help people deal with the lack of social contact. As a result, there was an increase in mental health problems, including insomnia and stress, with a negative impact on cardiovascular health. The objective of this research was to identify the association between insomnia and stress and cardiovascular risk (CVR) during the pandemic in a sample of the general population in Mexico; the participants were chosen using the non-probabilistic method. The data were obtained from an online questionnaire about medical histories focused on cardiovascular risk, according to the Official Mexican Standards and Regulations for patients' clinical records, NOM-004-SSA3-2012, along with an index for the severity of insomnia, measured with a seven-item guide, and an instrument to measure stress. The data were analyzed with descriptive statistics for several different variables: sociodemographics, stress, insomnia, and cardiovascular risk. Cardiovascular risk was compared to insomnia and stress variables, which led to statistically significant differences and correlations between the variables. Participants were divided into four groups with respect to CVR, from low to very high CVR. This research demonstrated that women were more susceptible to stress and cardiovascular risk. However, stress was a more major indicator of CVR than insomnia, but in the high and very high CVR groups, insomnia contributed along with stress; coping strategies reduced the risk in the high CVR group but did not function as expected with respect to reducing risk in the very high CVR group. These findings suggest that sleep patterns and mental health alterations present during the pandemic may persist even when the pandemic was declared as having ended and may contribute to increases in cardiovascular risk in the long-term.

BACKGROUND AND OBJECTIVES: It is well known that lipid abnormalities exist in the context of non-alcoholic fatty liver disease (NAFLD). The association between lipoprotein(a) [Lp(a)] levels and NAFLD is poorly understood. The main objective of the present study was to assess the association between Lp(a) levels and NAFLD. METHODS: This systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO CRD42023392526). A literature search was performed to detect studies that evaluated the association between Lp(a) levels, NAFLD and steatohepatitis (NASH). RESULTS: Ten observational studies, including 40,045 patients, were identified and considered eligible for this systematic review. There were 9266 subjects in the NAFLD groups and 30,779 individuals in the respective control groups. Five studies evaluated patients with NAFLD (hepatic steatosis was associated with lower Lp(a) levels in four studies, while the remaining showed opposite results). Two studies evaluating NASH patients showed that Lp(a) levels were not different compared to controls. However, the increment of Lp(a) levels was correlated with liver fibrosis in one of them. In addition, one study analyzed simultaneously patients with NAFLD and NASH, showing a neutral result in NAFLD patients and a positive relationship in NASH patients. Two studies that included patients with the new definition of metabolic-associated fatty liver disease (MAFLD) also showed neutral results. CONCLUSION: Although there could be an association between Lp(a) levels and hepatic steatosis, the results of the studies published to date are contradictory and not definitive.
RESUMO
This review summarizes the impact of gender affirming hormone therapy used in the transgendered population and the classic and emerging risk factors on cardiovascular outcomes and surrogate markers of cardiovascular health. There is a growing body of evidence that people who are transgender and gender diverse are impacted by disparities across a variety of cardiovascular risk factors compared with their peers who are cisgender. Previously, disparities have been reported in cardiovascular morbidity and mortality across this group as a result of a higher prevalence of non-healthy life style. However, recent research suggests that there are additional factors playing a role in this differences: there is the hypothesis that the excess of cardiovascular morbility and mortality has been driven by psychosocial stressors across the lifespan at multiple levels, as structural violence (e.g., discrimination, lack of affordable housing, lack of access to health care, etc.). Lack of information and research in this population is an important limitation; therefore, a multifaceted approach that integrates best practice into research, health promotion and cardiovascular care for this understudied and growing population is clearly needed.
Este artículo resume la literatura existente hasta este momento sobre el impacto de la terapia hormonal para la asignación de género utilizada en la población transgénero, y de los factores de riesgo tradicionales y emergentes, en los desenlaces cardiovasculares o los marcadores subrogados de enfermedad cardiovascular. Actualmente se reconoce la evidencia creciente de que las personas transgénero o con género diverso son víctimas de disparidades en una gran variedad de factores de riesgo cardiovascular comparadas con sus pares cisgénero. Se ha reportado disparidad en morbilidad y mortalidad como resultado de una alta prevalencia en estilos de vida no saludables. Sin embargo, recientemente se ha incorporado la interpretación de que no solo la disparidad en factores de riesgo cardiovascular es lo que incrementa el riesgo en la salud cardiovascular de la población transgénero. Existe la hipótesis de que el exceso en morbilidad y mortalidad cardiovascular está relacionado con estresores psicosociales a lo largo de la vida de este grupo en múltiples niveles, incluyendo violencia estructurada (p. ej., discriminación, falta de acceso a los servicios de salud, falta de vivienda digna, etc.). La falta de información y de investigación en este grupo son limitantes importantes que requieren un abordaje multifacético para mejorar aspectos como la promoción de la salud y el mejor cuidado cardiovascular.

Introducción: Las enfermedades cardiovasculares constituyen la principal causa de morbimortalidad a escala mundial. Otra enfermedad con impacto significativo en los sistemas de salud pública es el VIH/sida. Los pacientes infectados con el virus de la inmunodeficiencia humana, tienen mayor riesgo de desarrollar enfermedades cardiovasculares. Posterior al tratamiento antirretroviral ha disminuido la incidencia de enfermedades oportunistas asociadas al VIH/sida, y se ha elevado la incidencia de enfermedades asociadas al envejecimiento, como la enfermedad cardiovascular. El uso de antirretrovirales inhibidores de la proteasa se asocia a hiperlipidemia y, por consiguiente, al aumento de complicaciones cardiovasculares. Objetivo: Determinar los marcadores lipídicos en pacientes con VIH/sida en tratamiento con inhibidores de la proteasa. Materiales y métodos: Se realizó un estudio observacional, analítico, transversal en los pacientes con VIH/sida de la provincia de Matanzas, durante el período comprendido entre marzo y agosto de 2020, en el Laboratorio Clínico del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández. Resultados: Se evaluaron los marcadores lipídicos como factor de riesgo cardiovascular asociado al tratamiento antirretroviral, siendo los triglicéridos el de mayor incidencia. Conclusiones: Se identificaron los marcadores lipídicos como factores de riesgo cardiovascular, en este caso la hipertrigliceridemia.
Introduction: Cardiovascular diseases are the main risk of morbidity and mortality worldwide. Another disease with significant impact on public health systems is HIV/AIDS. Patients infected with the human immunodeficiency virus have a higher risk of developing cardiovascular diseases. After antiretroviral treatment, the incidence of opportunistic diseases associated with HIV/AIDS has decreased and the incidence of diseases associated with aging such as cardiovascular disease has increased. The use of protease inhibitor antiretroviral drugs is associated with hyperlipidemia and a consequent increase in cardiovascular complications. Objective: To determine lipid markers in patients with HIV/AIDS undergoing treatment with protease inhibitors. Materials and method: An observational, analytical, cross-sectional study was carried out in patients with HIV/AIDS from the province of Matanzas during the period from March to August 2020, in the Clinical Laboratory of the Provincial Teaching Clinical Surgical Hospital Faustino Pérez Hernandez. Results: Lipid markers were evaluated as cardiovascular risk factor associated with antiretroviral treatment, with triglycerides being the one of highest incidence. Conclusions: Lipid markers were identified as cardiovascular risk factors; in this case hypertriglyceridemia.

INTRODUCTION: During adolescence, dairy product intake has shown conflicting associations with metabolic syndrome (MetS) components, which are risk factors for cardiovascular disease (CVD). This study aims to investigate the association between plasma fatty acids (FAs) C15:0, C17:0, and t-C16:1n-7, as biomarkers of dairy intake, with MetS and its components in Mexican adolescents. METHODS: A sample of 311 participants from the Early Life Exposure in Mexico City to Environmental Toxicants (ELEMENT) cohort was included in this cross-sectional analysis. FA concentrations were measured in plasma as a percentage of total FA. We used quantile regression models stratified by sex to evaluate the association between FA quantiles and MetS components, adjusting for age, socioeconomic status (SES), sedentary behavior, BMI z-score, pubertal status, and energy intake. RESULTS: We found significant associations between dairy biomarkers and the median of MetS variables. In females, t-C16:1n-7 was associated with a decrease of 2.97 cm in WC (Q4 vs. Q1; 95% CI: -5.79, -0.16). In males, C15:0 was associated with an increase of 5.84 mm/Hg in SBP (Q4 vs. Q1; CI: 1.82, 9.85). For HDL-C, we observed opposite associations by sex. C15:0 in males was associated with decreased HDL-C (Q3 vs. Q1: ß = -4.23; 95% CI: -7.98, -0.48), while in females, C15:0 and t-C16:1n-7 were associated with increased HDL-C (Q3 vs. Q1: ß = 4.75; 95% CI: 0.68, 8.82 and Q4 vs. Q1: ß = 6.54; 95% CI: 2.01, 11.07), respectively. Additionally, in both sexes, different levels of C15:0, C17:0, and t-C16:1n-7 were associated with increased triglycerides (TG). CONCLUSION: Our results suggest that adolescent dairy intake may be associated in different directions with MetS components and that associations are sex-dependent.

Objective: To analyze the agreement between body mass index (BMI) and waist-to-height Ratio (WHtR) to identify preschool and school children with cardiovascular risk factors (CRFs). Methods: Three-hundred-twenty-one kids were divided into preschool (3-5 years) and school children (6-10 years). BMI was used to classify children as overweight or obese. Abdominal obesity was defined with a WHtR ≥0.50. Fasting blood lipids, glucose and insulin were measured, and the homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. The presence of CRFs and multiple non-waist circumference (non-WC) metabolic syndrome factors (MetS-Factors) [high HOMA-IR, high triglycerides and low high-density lipoprotein cholesterol (HDL-C)] were analyzed. Results: One-hundred-twelve preschool and 209 school children were evaluated. WHtR ≥0.50 classified abdominal obesity in more than half of the preschool children, exceeding those classified with overweight+obesity by BMI (59.5% vs. 9.8%; p<0.001). There was no agreement between WHtR and BMI to identify preschool kids with CRFs and multiple non-WC MetS-Factors (kappa: 0.0 to 0.23, p>0.05). There were similar proportions of school children classified with abdominal obesity by the WHtR and overweight+obesity by the BMI (18.7% vs. 24.9%; p>0.05). There was substantial agreement between WHtR and BMI to identify school children with high total cholesterol values, low-density lipoprotein cholesterol (LDL-C), triglycerides, non-HDL-C, insulin, HOMA-IR, low HDL-C values, and the presence of multiple non-WC MetS-Factors (kappa: 0.616 to 0.857, p<0.001). Conclusion: In preschool children WHtR ≥0.5 disagree with BMI results, but in school kids, it has good agreement with the BMI to classify the children´s nutritional status and to identify those with CRFs.
Objetivo: Analizar el grado de acuerdo entre el índice de masa corporal (IMC) y la relación/cintura estatura (rCE) para identificar niños con factores de riesgo cardiovascular (FRC). Métodos: Estudio transversal analítico con 112 niños preescolares (3-5 años) y 209 escolares (6-10 años). El sobrepeso y la obesidad se clasificaron con el IMC y la obesidad abdominal con la rCE ≥0.50. Se tomaron muestras sanguíneas en ayuno para análisis de glucosa, insulina, lípidos y cálculo del índice HOMA-IR. Se analizó la presencia de FRC y de múltiples factores del síndrome metabólico (Factores-SinMet) diferentes a la cintura [HOMA-IR elevado, triglicéridos elevados y colesterol de alta densidad (HDL-C) bajo]. Resultados: rCE ≥0.50 clasificó con obesidad abdominal a más de la mitad de los niños preescolares, excediendo el número de niños clasificados con sobrepeso+obesidad por IMC (59.5% vs 9.8%; p<0.001). No hubo acuerdo entre el IMC y la rCE para identificar niños preescolares con FRC o múltiples Factores-SinMet diferentes a la cintura (kappa: 0.0 a 0.23, p>0.05). Fueron similares las proporciones de niños escolares clasificados con obesidad abdominal por la rCE o con sobrepeso+obesidad por el IMC (18.7% vs. 24.9%; p>0.05). Hubo acuerdo sustancial entre la rCE y el IMC para identificar niños escolares con valores elevados de colesterol total, colesterol de baja densidad, triglicéridos, colesterol no-HDL, insulina, HOMA-IR, valores bajos de HDL-C y la presencia de múltiples Factores-SinMet diferentes a la cintura (kappa: 0.616 a 0.857, p<0.001). Conclusión: En niños preescolares la aplicación de rCE ≥0.5 no presenta acuerdo con el IMC, pero en escolares presenta un acuerdo sustancial con el IMC en la clasificación del estado nutricional y en la identificación de niños con FRC.

Los informes de laboratorio tienen impacto en las decisiones médicas. El ayuno es un factor preanalítico "controlable" que influye en los distintos parámetros bioquímicos. El objetivo del presente trabajo es poner en discusión la realización en pediatría de análisis clínicos con la indicación de un ayuno fisiológico , analizando resultados obtenidos por diferentes autores y evaluando las diferencias clínicas encontradas según los criterios de calidad establecidos por el laboratorio de Química Clínica. La mayoría de los individuos durante el día se encuentran en estado postprandial. Los resultados del perfil lipídico en ayunas no representan las concentraciones reales promedios de los lípidos plasmáticos de un paciente. El ayuno no sería crítico en la etapa de pesquisa , pero puede ser relevante para establecer un diagnóstico certero o inicio de tratamiento. En el caso de la glucemia si se indica en el control rutinario del paciente, y no hay sospecha de alteraciones en el metabolismo de los hidratos de carbono la glucemia sin ayuno puede ser solicitada comparando la misma con valores de corte adecuado. Las diferentes guías nacionales e internacionales recomiendan que la elección de la métrica para la evaluación, control y seguimiento de pacientes con diagnóstico de diabetes se realicen según el objetivo terapéutico. En los trabajos analizados, observamos que varios parámetros bioquímicos presentaron diferencias estadísticas, aunque las diferencias clínicas no fueron relevantes y permanecieron dentro de los intervalos de referencia. El factor limitante para evaluar parámetros bioquímicos sin ayuno es la falta de valores de referencia adecuados. Hay evidencia suficiente para que tanto el perfil lipídico, la glucemia como el resto de los parámetros bioquímicos del laboratorio de química clínica, sean solicitados con la indicación de un ayuno fisiológico de 2, 4 o 6 horas, dependiendo siempre del motivo de consulta y/o la edad del paciente. Es esencial extender la evaluación a otros analitos en población pediátrica, así como evaluar nuevos puntos de corte para parámetros bioquímicos sin ayuno (AU)
Laboratory reports have an impact on medical decision-making. Fasting is a "controllable" preanalytical factor that influences the different biochemical parameters. The aim of this study is to discuss the performance of clinical analyses in pediatrics with the indication of physiological fasting, analyzing results obtained in different disciplines, and evaluating the clinical differences found according to the quality criteria established by the clinical chemistry laboratory. During the day, most patients are in a postprandial state. Fasting lipid profile results do not represent the actual average plasma lipid concentrations of a patient. Fasting would not be critical in the screening stage, but it may be relevant to establish an accurate diagnosis or initiate treatment. Regarding glycemia, if it is indicated in the routine control of the patient and there is no suspicion of alterations in carbohydrate metabolism, non-fasting glycemia can be requested, comparing it with adequate cut-off values. Different national and international guidelines recommend that the choice of metrics for the evaluation, control, and follow-up of patients with diabetes should be made according to the therapeutic objective. In the studies analyzed, we found that several biochemical parameters presented statistical differences, although the clinical differences were not relevant and remained within the reference range. The limiting factor in the evaluation of biochemical parameters without fasting is the lack of adequate reference values. There is sufficient evidence that the lipid profile, glycemia, and the remaining biochemical parameters of the clinical chemistry laboratory should be requested with the indication of a physiological fast of 2, 4, or 6 hours, always depending on the reason for consultation and/or the patient's age. It is essential to extend the evaluation to other analytes in the pediatric population, as well as to evaluate new cut-off points for biochemical parameters without fasting (AU)
