RESUMO

Salt stress causes several physiological and biochemical disorders and impairs plant growth. However, adequate fertilization can improve the nutritional status and may reduce significantly the harmful effects caused by salt stress. From this perspective, this study aimed to evaluate the impact of different combinations of nitrogen, phosphorus and potassium fertilization on the antioxidant activity and accumulation of organic and inorganic solutes in West Indian cherry leaves, in the second year of production. The experimental design was in randomized blocks, with treatments distributed in a 10 × 2 factorial arrangement corresponding to ten fertilization combinations (FC) of NPK (FC1: 80-100-100%, FC2:100-100-100%, FC3:120-100-100%, FC4:140-100-100%, FC5:100-80-100%, FC6:100-120-100%, FC7:100-140-100%, FC8:100-100-80%, FC9:100-100-120%, and FC10:100-100-140% of the recommendation) and two levels of electrical conductivity of irrigation water (ECw) (0.6 and 4.0 dS m-1), with three replications. The multivariate analysis showed that irrigation with water of different electrical conductivities (0.6 and 4.0 dS m-1) resulted in different responses concerning the enzyme activity, production of organic compounds, and accumulation of inorganic solutes in the leaves. Under irrigation with low salinity water, there was greater accumulation of K+, soluble carbohydrates, and proline, and lower activity of antioxidative enzymes, especially SOD and APX. Under high salinity water, greater enzyme activity and higher concentrations of Na+ and Cl- were observed. The results indicate that the response of West Indian cherry to salinity was more towards redox homeostasis than osmotic homeostasis through the accumulation of compatible solutes. Fertilization combination FC5 (100-80-100% corresponding to 200, 24 and 80 g plant-1 of NPK) modulates the enzyme activity of SOD and APX attenuating the impacts of salinity, being an efficient combination to preserve redox homeostasis in West Indian cherry plants grown under salt stress.

RESUMO

With the increase in uptake of multi-month antiretroviral therapy dispensing (MMD) for children, little is known about consistency of MMD receipt over time and its association with virological outcomes. This analysis aims to assess the uptake of 3-month MMD among children, consistent receipt of MMD after uptake, and clinical outcomes following transition to MMD in 16 health facilities in Gaza and Inhambane Provinces. This is a secondary analysis involving children <15 years living with HIV with clinical visits during the period from September 2019 to August 2020. Of 4383 children, 82% ever received MMD (at least one pickup of a 3-month MMD supply) during the study period but only 40% received it consistently (defined as MMD at every visit during the study period). Consistent MMD was most common among older children and children without indications of clinical instability. Overall viral load (VL) coverage was 40% (733/1851). Consistent MMD was significantly associated with lower odds of having a VL (0.78, 95% CI: 0.64-0.95). In conclusion, while receipt of a multi-month supply was common particularly during the early days of the COVID-19 pandemic, only a minority of children received consistent MMD; however, there is a need to ensure children with fewer visits still receive timely VL monitoring.

RESUMO

West Indian cherry cultivation has proved to be an important economic activity in northeastern Brazil. However, irrigation with brackish waters limits cultivation, requiring new strategies to minimize the effect of salt stress. In this context, the present study aimed to evaluate the effect of nitrogen (N), phosphorus (P), and potassium (K) combinations on the photosynthetic pigments and quantum yield of West Indian cherry cultivated under salt stress, in the second year of production. The assay was conducted in a protected environment by adopting an experimental design in randomized blocks, with treatments distributed in a 2×10 factorial arrangement referring to two electrical conductivity levels of irrigation water - ECw (0.6 and 4.0 dS m-1) and 10 NPK fertilization combinations - FC (80-100-100; 100-100-100; 120-100-100; 140-100-100; 100-80-100; 100-120-100; 100-140-100; 100-100-80; 100-100-120, and 100-100-140% of the recommendation, in the second year of production), with three replications, each consisting of one plant. Irrigation with the electrical conductivity of 4.0 dS m-1 negatively affected the synthesis of photosynthetic pigments and the photochemical efficiency of the West Indian cherry cv. Flor Branca. The NPK combinations did not attenuate the effects of salt stress on the analyzed variables. However, the combinations referring to 120-100-100%, 140-100-100%, and 100-120-100% of NPK recommendation improved the quantum yield of photosystem II by reducing the initial fluorescence and increasing the maximum fluorescence of the West Indian cherry cv. Flor Branca.

RESUMO

BACKGROUND: The new criteria of Cirrhotic Cardiomyopathy Consortium (CCC) propose the use of left ventricular global longitudinal strain (LV-GLS) for evaluation of systolic function in patients with cirrhosis. The aim of this study was to evaluate LV-GLS and left atrial (LA) strain in association with the severity of liver disease and to assess the characteristics of cirrhotic cardiomyopathy (CCM). METHODS: One hundred and thirty-five cirrhotic patients were included. Standard echocardiography and speckle tracking echocardiography (2D-STE) were performed, and dual X-ray absorptiometry was used to quantify the total and regional fat mass. CCM was defined, based on the criteria of CCC, as having advanced diastolic dysfunction, left ventricular ejection fraction ≤50% and/or a GLS <18%. RESULTS: LV-GLS lower or higher than the absolute mean value (22.7%) was not associated with mortality (logrank, p = 0.96). LV-GLS was higher in patients with Model for end stage liver disease (MELD) score ≥15 compared to MELD score <15 (p = 0.004). MELD score was the only factor independently associated with systolic function (LV-GLS <22.7% vs. ≥22.7%) (Odds Ratio:1.141, p = 0.032). Patients with CCM (n = 11) had higher values of estimated volume of visceral adipose tissue compared with patients without CCM (median: 735 vs. 641 cm3 , p = 0.039). On multivariable Cox regression analysis, MELD score [Hazard Ratio (HR):1.26, p < 0.001] and LA reservoir strain (HR:0.96, p = 0.017) were the only factors independently associated with the outcome. CONCLUSION: In our study, absolute LV-GLS was higher in more severe liver disease, and LA reservoir strain was significantly associated with the outcome in patients with end-stage liver disease.

RESUMO

PURPOSE: Cardiovascular disease is commonly accompanied by renal dysfunction. Multimorbidity in hospitalized patients impacts unfavorably on prognosis and hospital stay. We aimed to illustrate the contemporary burden of cardiorenal morbidity across inpatient cardiology care in Greece. METHODS: The Hellenic Cardiorenal Morbidity Snapshot (HECMOS) used an electronic platform to collect demographic and clinically relevant information about all patients hospitalized on March 3, 2022, in Greece. The participating institutions covered all levels of inpatient cardiology care and most of the country's territories to collect a real-world, nation representative sample. RESULTS: A total of 923 patients (men 68.4%, median age 73 ± 14.8 years) were admitted to 55 different cardiology departments. 57.7% of the participants were aged >70 years. Hypertension was highly prevalent and present in 66% of the cases. History of chronic HF, diabetes mellitus, atrial fibrillation, and chronic kidney disease was present in 38%, 31.8%, 30%, and 26%, respectively. Furthermore, 64.1% of the sample exhibited at least one of these 4 entities. Accordingly, a combination of ≥2 of these morbid conditions was recorded in 38.7%, of ≥3 in 18.2%, whereas 4.3% of the sample combined all 4 in their medical history. The most common combination was the coexistence of heart failure-atrial fibrillation accounting for 20.6% of the sample. Nine of 10 nonelectively admitted patients were hospitalized due to acute HF (39.9%), acute coronary syndrome (33.5%), or tachyarrhythmias (13.2%). CONCLUSION: HECMOS participants carried a remarkable burden of cardio-reno-metabolic disease. HF in conjunction with atrial fibrillation was found to be the most prevalent combination among the studied cardiorenal nexus of morbidities in the whole study population.

RESUMO

Background and Aim: The Goliath chicken is a slow-growing chicken with a high slaughter weight but whose carcass characteristics and meat quality have not yet been documented. This study aimed to evaluate the effect of age at slaughter and sex on the carcass characteristics and technological and sensory meat quality of Goliath chickens raised in southern Benin. Materials and Methods: Data on the carcass characteristics and technological and sensory quality of meat were collected from 80 chickens raised in confinement and divided into two groups. The first group was reared for 12 weeks of age and the second group was for 20 weeks of age. The animals were individually weighed using an electronic balance (Terraillon 5000g) and then slaughtered. The different parts of the chicken carcass was weighed using the same method. Results: The live, hot carcass, cold carcass, wing, thigh, and tail weights of males were significantly greater than those of females (p < 0.01). The wishbone muscle and thigh and tail assembly pH was lower in the 20-week-old chickens than in the 12-week-old chickens. The brightness and red index of the wishbone of the 20-week-old chickens were significantly higher than those of the 12-week-old chickens (p < 0.001). The red index of the wishbone and the yellow index of the thigh and tail assembly of females were lower than those of males. Conclusion: The meat of 20-week-old Goliath chickens was juicier than that of 12-week-old chickens. Thus, the carcass composition of Goliath chickens is better at 20 weeks of age, especially in males.

RESUMO

Regular and long-term monitoring of coastal areas is a prerequisite to avoiding or mitigating the impacts of climate and human-driven hazards. In Africa, where populations and infrastructures are particularly exposed to risk, there is an urgent need to establish coastal monitoring, as observations are generally scarce. Measurement campaigns and very high-resolution satellite imagery are costly, while freely available satellite observations have temporal and spatial resolutions that are not suited to capture the event scale. To address the gap, a network of low-cost, multi-variable, shore-based video camera systems has been installed along the African coasts. Here, we present this network and its principle of sharing data, methods, and results obtained, building toward the implementation of a common integrated coastal management policy between countries. Further, we list new contributions to the understanding of still poorly documented African beaches' evolution, waves, and sea level impacts. This network is a solid platform for the development of inter-disciplinary observations for resources and ecology (such as fisheries, and sargassum landing), erosion and flooding, early warning systems during extreme events, and science-based coastal infrastructure management for sustainable future coasts.

RESUMO

Rare cardiovascular diseases (RCDs) have low incidence but major clinical impact. RCDs' classification includes Class I-systemic circulation, Class II-pulmonary circulation, Class III-cardiomyopathies, Class IV-congenital cardiovascular diseases (CVD), Class V-cardiac tumors and CVD in malignancy, Class VI-cardiac arrhythmogenic disorders, Class VII-CVD in pregnancy, Class VIII-unclassified rare CVD. Cardiovascular Magnetic Resonance (CMR) is useful in the diagnosis/management of RCDs, as it performs angiography, function, perfusion, and tissue characterization in the same examination. Edema expressed as a high signal in STIRT2 or increased T2 mapping is common in acute/active inflammatory states. Diffuse subendocardial fibrosis, expressed as diffuse late gadolinium enhancement (LGE), is characteristic of microvascular disease as in systemic sclerosis, small vessel vasculitis, cardiac amyloidosis, and metabolic disorders. Replacement fibrosis, expressed as LGE, in the inferolateral wall of the left ventricle (LV) is typical of neuromuscular disorders. Patchy LGE with concurrent edema is typical of myocarditis, irrespective of the cause. Cardiac hypertrophy is characteristic in hypertrophic cardiomyopathy (HCM), cardiac amyloidosis (CA) and Anderson-Fabry Disease (AFD), but LGE is located in the IVS, subendocardium and lateral wall in HCM, CA and AFD, respectively. Native T1 mapping is increased in HCM and CA and reduced in AFD. Magnetic resonance angiography provides information on aortopathies, such as Marfan, Turner syndrome and Takayasu vasculitis. LGE in the right ventricle is the typical finding of ARVC, but it may involve LV, leading to the diagnosis of arrhythmogenic cardiomyopathy. Tissue changes in RCDs may be detected only through parametric imaging indices.

RESUMO

The association between population increase and the exploitation of natural resources and climate change influences the demand for food, especially in semi-arid regions, highlighting the need for technologies that could provide cultivated species with better adaptation to agroecosystems. Additionally, developing cultivation technologies that employ waste materials is highly desirable for sustainable development. From this perspective, this study aimed to evaluate whether seed priming with glass waste microparticles used as a silicon source under red light irradiation mitigates the effects of thermal and water stress on seedlings of Moringa oleifera. The experimental design was set up in randomized blocks using a 2 × 2 × 2 factorial arrangement consisting of seed priming (NSP-no seed priming, and SPSi-seed priming with glass microparticles under red light irradiation), soil water replenishment (W50-50%, and W100-100% of crop evapotranspiration-ETc), and temperature change (TC30°-30 °C day/25 °C night and TC40°-40 °C day/35 °C night). Seed priming with glass microparticles under red light irradiation mitigated the effects of thermal and water stress on seedlings of Moringa oleifera seedlings through the homeostasis of gas exchange, leaf water status, osmotic adjustment, and the antioxidant mechanism.

RESUMO

BACKGROUND AND AIM: Insulin resistance (IR) is associated with a higher rate of type 1 diabetes (T1D) complications. We aimed to examine the relationship between estimated glucose disposal rate (eGDR), a readily available marker of IR in clinical practice and early predictor biomarkers of macrovascular and microvascular complications in patients with T1D. DESIGN: A cross-sectional study. METHODS: A total of 165 consecutive patients with T1D free of cardiovascular, eye, and renal complications were included in the study from 2016 to 2020. Participants were characterized as insulin resistant if their eGDR value was ≤ 8 mg/kg/min. Pulse wave velocity (PWV) and global longitudinal strain (GLS) were used as surrogates for subclinical atherosclerosis and left ventricular systolic dysfunction (LVSD), respectively. Four previously standardized tests based on the calculation of heart rate variability (HRV) were used to evaluate subclinical cardiac autonomic neuropathy (CAN). Early nephropathy was assessed by assessing urinary albumin to creatinine ratio (ACR). RESULTS: The population sample (n = 165) included a majority of female patients (63%) and had a median age of 32 years (24-43), median disease duration of 14 years ( ± 9.5-21.5), a median BMI value of 23.7 kg/m2 (21.4-26.6), an HbA1C of 7.2% (6.7-8.2) and median eGDR (lower values indicate higher insulin resistance) of 9.2 mg/kg/min (8.2-9.9), while 21.8% (n = 36) of the participants were characterized as insulin resistant. After adjustment for age, gender, and the duration of diabetes, the presence of IR was significantly associated with higher prevalence of subclinical atherosclerosis (OR:2.59, 95% CI: 1.06-6.30, p = 0.036), CAN (OR:3.07, 95% CI: 1.02-9.32, p = 0.047) and subclinical LVSD (OR: 4.9, 95% CI: 1.94-12.79, p = 0.001). No association was shown with ACR. CONCLUSIONS: In patients with T1D, insulin resistance, as measured by eGDR, correlates well with early CVD predictors and CAN. These associations appear independent of the effects of gender, aging, and disease duration.

RESUMO

Heart failure (HF) patients frequently develop brain deficits that lead to cognitive dysfunction (CD), which may ultimately also affect survival. There is an important interaction between brain and heart that becomes crucial for survival in patients with HF. Our aim was to review the brain/heart interactions in HF and discuss the emerging role of combined brain/heart magnetic resonance imaging (MRI) evaluation. A scoping review of published literature was conducted in the PubMed EMBASE (OVID), Web of Science, Scopus and PsycInfo databases. Keywords for searches included heart failure, brain lesion, brain, cognitive, cognitive dysfunction, magnetic resonance imaging cardiovascular magnetic resonance imaging electroencephalogram, positron emission tomography and echocardiography. CD testing, the most commonly used diagnostic approach, can identify neither subclinical cases nor the pathophysiologic background of CD. A combined brain/heart MRI has the capability of diagnosing brain/heart lesions at an early stage and potentially facilitates treatment. Additionally, valuable information about edema, fibrosis and cardiac remodeling, provided with the use of cardiovascular magnetic resonance, can improve HF risk stratification and treatment modification. However, availability, familiarity with this modality and cost should be taken under consideration before final conclusions can be drawn. Abnormal CD testing in HF patients is a strong motivating factor for applying a combined brain/heart MRI to identify early brain/heart lesions and modify risk stratification accordingly.

RESUMO

BACKGROUND: Human immunodeficiency virus (HIV) is mainly detected in young, otherwise healthy, individuals. Cardiomyopathy and peripheral artery disease affecting these patients appears to be multifactorial. Prompt and potentially more effective implementation of therapeutic measures could be enabled by pre-symptomatic diagnosis of myocardial dysfunction and peripheral artery damage. However, limited data is available to date on this specific topic. Μethods: We investigated the association between global longitudinal strain (GLS), an established index of subclinical left ventricular systolic dysfunction (LVSD) assessed by two-dimensional speckle-tracking echocardiography, and: (a) patient history; (b) demographic and clinical baseline characteristics; (c) carotid intima-media thickness (IMT) and the presence of carotid atherosclerotic plaque(s), measured by ultrasonography; (d) temperature difference (ΔT) along each carotid artery, measured by microwave radiometry; and (e) basic blood panel measurements, including high-sensitivity troponin-T (hsTnT) and NT-proBNP in people living with HIV (PLWH) and no history of cardiovascular disease. RESULTS: We prospectively enrolled 103 consecutive PLWH (95% male, age 47 ± 11 years, anti-retroviral therapy 100%) and 52 age- and sex-matched controls. PLWH had a significantly higher relative wall thickness (0.38 ± 0.08 vs. 0.36 ± 0.04, p = 0.048), and higher rate of LVSD (34% vs. 15.4%, p = 0.015), and carotid artery atherosclerosis (28% vs. 6%, p = 0.001) compared with controls. Among PLWH, LVSD was independently associated with the presence of carotid atherosclerosis (adj. OR:3.09; 95%CI:1.10-8.67, p = 0.032) and BMI (1.15; 1.03-1.29, p = 0.017), while a trend for association between LVSD and left ventricular hypertrophy was also noted (3.12; 0.73-13.33, p = 0.124). No differences were seen in microwave radiometry parameters, NT-proBNP, hs-TnT and c-reactive protein between PLWH with and without LVSD. CONCLUSIONS: Subclinical LVSD and carotid atherosclerosis were significantly more frequent in PLWH compared to a group of healthy individuals, implying a possible link between HIV infection and these two pathological processes. Carotid atherosclerosis and increased adiposity were independently associated with impaired GLS in HIV-infected individuals.

RESUMO

A 30-year-old man with a history of an in-situ melanoma of the forehead was referred for cardiac evaluation because of tachycardia and elevated levels of serum troponin. The transthoracic echocardiogram revealed multiple masses attached to the walls of both ventricles and the right atrium (RA). A large mass was occupying almost one third of the right ventricle (RV), resulting in reduction of the end-diastolic RV volume and tachycardia. A cardiac magnetic resonance imaging confirmed multifocal myocardial infiltration and intracavitary masses and excluded the presence of thrombus in any of the cardiac chambers. Diffuse metastatic involvement in the liver, the spleen, and the brain by computed tomography precluded surgical management. Being BRAF-unmutated, the patient was initially treated with a combination of nivolumab and ipilimumab. One month later, the cardiac metastases in RA and left ventricle were unchanged on echocardiogram, while the tumor in RV was enlarged occupying the majority of the chamber, resulting in further reduction of the cardiac output and tachycardia. The treatment was changed to a combination of dacarbazine and carboplatin, but the patient eventually died two months later. Heart is not a common metastatic site of melanoma and cardiac involvement is usually clinically silent making ante mortem diagnosis difficult. Multimodalidy imaging plays a pivotal role in the diagnostic work up. Cardiac melanoma metastases indicate an advance stage disease with poor prognosis.

RESUMO

Background. Patients with inflammatory joint diseases (IJD) are more likely to develop cardiovascular disease compared with the general population. We hypothesized that cardiovascular magnetic resonance (CMR) could identify cardiac abnormalities in patients with IJD and atypical symptoms unexplained by routine clinical evaluation. Patients-Methods. A total of 51 consecutive patients with IJD (32 with rheumatoid arthritis, 10 with ankylosing spondylitis, and 9 with psoriatic arthritis) and normal clinical, electrocardiographic and echocardiographic workups, were referred for CMR evaluation due to atypical chest pain, shortness of breath, and/or palpitations. Their CMR findings were compared with those of 40 non-IJD controls who were referred for the same reason. All participants were examined using either a 1.5 T or 3.0 T CMR system. For T1/T2 mapping, comparisons were performed separately for each field strength. Results. Biventricular systolic function was similar between groups. In total, 25 (49%) patients with IJD vs. 0 (0%) controls had replacement-type myocardial fibrosis (p < 0.001). The T2 signal ratio, early/late gadolinium enhancement, and extracellular volume fraction were significantly higher in the IJD group. Native T1 mapping was significantly higher in patients with IJD independent of the MRI field strength (p < 0.001 for both). T2 mapping was significantly higher in patients with IJD compared with controls only in those examined using a 1.5 T MR system­52.0 (50.0, 55.0) vs. 37.0 (33.5, 39.5), p < 0.001. Conclusions. In patients with IJD and a mismatch between cardiac symptoms and routine non-invasive evaluation, CMR uniquely identified a significant proportion of patients with myocardial inflammation. A CMR examination should be considered in patients with IJD in similar clinical settings.

RESUMO

There is ongoing controversy regarding the association between loop diuretics (LD), especially in high doses, and adverse clinical outcomes in outpatients with heart failure (HF). We performed a systematic review of the evidence for LD in outpatients with HF. We searched MEDLINE, EMBASE, and Cochrane Clinical Trial Collection to identify controlled studies, evaluating the association between LD and morbidity and mortality in patients with HF. The primary endpoint was all-cause mortality and secondary endpoint HF hospitalizations. Quantitative analysis was performed by generating forest plots and pooling adjusted risk estimates across studies using random effects models. Between-study heterogeneity was assessed through Q and I2 statistics. Twenty-four studies with a total of 96,959 patients were included. No randomized studies were identified. Use of LD was associated with increased all-cause mortality compared with non-use (pooled adjusted risk estimates, 1.18; P = 0.001) and increased HF hospitalization rates (pooled adjusted risk estimates, 1.81; P < 0.001). These associations remained significant after excluding studies that included HF patients at discharge from hospital (pooled adjusted risk estimates, 1.31 and 1.89, respectively; P < 0.001 for both). High-dose LD (median dose 80 mg) were also associated with increased all-cause mortality (pooled adjusted risk estimates, 1.99; P < 0.001) compared with low-dose LD. Again, this association remained significant after excluding studies that included HF patients at discharge from hospital (pooled adjusted risk estimates, 1.33; P < 0.001). Existing evidence indicates that LD, especially in high doses, are associated with increased all-cause mortality and HF hospitalization rates. For this reason, prospective, randomized studies are warranted to clarify whether these associations indicate causality or are merely an epiphenomenon due to disease severity.

RESUMO

Objectives: Optimal regulation of modifiable risk factors has been proposed as the standard of care both for primary and secondary prevention of cardiovascular disease (CVD). The aim of this study was to assess primary and secondary cardiovascular risk management received before admission for an acute coronary event. Methods: Data were analyzed for 185 consecutive hospitalized patients with a diagnosis of acute coronary syndrome (ACS) in the Cardiology department of a University hospital during an annual period (1/7/2019 until 30/6/2020). The study population was divided into two groups, the primary and secondary prevention subgroups, according to previous medical history of cardiovascular disease (CVD). Results: The mean age of the participants was 65.5 ±12.2 years and most patients were male (81.6%). Previous CVD was present in 51 patients (27.9%). Fifty-seven patients (30.8%) had a history of diabetes mellitus (DM) and 97 (52.4%) had a history of dyslipidemia. Hypertension was present in 101 (54.6%) patients. In the secondary prevention group, the LDL-C was on target in only 33.3% of the patients, while 20% patients did not use statins. The use of antiplatelet/anticoagulant agents was 94.5%. Among patients with diabetes, only 20% had been using a GLP-1 receptor agonist or/and an SGLT-2 inhibitor, while the HbA1c was on target in 47.8%. Twenty-five percent of the patients were active smokers. In the primary prevention group, the use of statins was overall low (25.8%) but more frequent in patients with diabetes and those without diabetes at very high-risk for CVD (47.1% and 32.1% respectively). The LDL-C was on target in less than 23.1% of the patients. The use of antiplatelet/anticoagulant agents was low (20.1%), but higher in those with diabetes (52.9%). In the diabetic group, HbA1c was on target in 61.8%. Active smoking was practiced by 46.3% of the patients. Conclusions: Our data show that in a substantial proportion of patients presenting with ACS, previous CVD prevention, both primary and secondary, fails to meet the current recommendations provided by scientific societies.

RESUMO

BACKGROUND: With the number of people living with human immunodeficiency virus (HIV) steadily increasing, cardiovascular disease has emerged as a leading cause of non-HIV related mortality. People living with HIV (PLWH) appear to be at increased risk of coronary artery disease and heart failure (HF), while the underlying mechanism appears to be multifactorial. In the general population, ectopic cardiac adiposity has been highlighted as an important modulator of accelerated coronary artery atherosclerosis, arrhythmogenesis and HF with preserved ejection fraction (HFpEF). Cardiac adiposity is also strongly linked with obesity, especially with visceral adipose tissue accumulation. AIMS: This review aims to summarize the possible role of cardiac fat depositions, assessed by imaging modalities,as potential contributors to the increased cardiac morbidity and mortality seen in PLWH, as well as therapeutic targets in the current ART era. MATERIALS & METHODS: Review of contemporary literature on this topic. DISCUSSION: Despite antiretroviral therapy (ART), PLWH have evidence of persistent, HIV-related systemic inflammation and body fat alterations. Cardiac adiposity can play an additional role in the pathogenesis of cardiovascular disease in the HIV setting. Imaging modalities such as echocardiography, cardiac multidetector computed tomography and cardiac magnetic resonance have demonstrated increased adipose tissue. Studies show that high cardiac fat depots play an additive role in promoting coronary artery atherosclerosis and HFpEF in PLWH. Systemic inflammation due to HIV infection, metabolic adverse effects of ART, adipose alterations in the ageing HIV population, inflammation and immune activation are likely important mechanisms for adipose dysfunction and disproportionately occurrence of ectopic fat depots in the heart among PLWH. CONCLUSIONS: High cardiac adiposity seems to plays an additive role in promoting coronary artery atherosclerosis and HFpEF in PLWH. The underlying mechanisms are multiple and warrant further investigation. Improved understanding of the regulating mechanisms that increase cardiovascular risk in HIV infection may give rise to more tailored therapeutic strategies targeting cardiac fat depots.

RESUMO

AIMS: Prevalence and risk factors of pre-symptomatic left ventricular systolic dysfunction (LVSD) in individuals with type 1 diabetes (T1D) have not been adequately studied. The present cross-sectional study assessed the prevalence of early LVSD in asymptomatic patients with type 1 diabetes and investigated potential risk factors. METHODS: Consecutive patients with T1D, free of cardiovascular disease and significant evident microvascular complications were examined. LVSD was assessed by speckle-tracking echocardiography and calculation of global longitudinal strain (GLS). Abnormal GLS was defined as a value>-18.7%. We looked for possible associations between the presence of LVSD and patient demographic, clinical and laboratory characteristics, as well as with autonomic nervous system (ANS) function and arterial stiffness. RESULTS: We enrolled 155 T1D patients (29.7% men, age 36.7 ±â€¯13.1 years, diabetes duration 19.1 ±â€¯10.0 years, HbA1c 7.5 ±â€¯1.4% [58 ±â€¯15 mmol/mol]). Early LVSD was prevalent in 53 (34.2%) patients. Multivariable analysis identified male gender (OR:4.14; 95% CI:1.39-12.31, p = 0.011), HbA1c (OR:1.59 per 1% increase; 95% CI:1.11-2.28, p = 0.011), glomerular filtration rate (GFR, OR:0.97; 95% CI:0.95-0.99, p = 0.010) and BMI (OR:1.19; 95% CI:1.06-1.34, p = 0.003) as independent predictors of LVSD presence. CONCLUSIONS: Early subclinical LVSD is a common finding in asymptomatic patients with T1D, free of macrovascular and significant microvascular complications. Apart from chronic hyperglycemia, increased adiposity may be implicated in its etiology. Further investigation is warranted to identify patients at high risk for whom early screening is required and to determine possible associations between risk markers identified in the present analysis and long-term outcomes.
