Longitudinal changes of angiogenic factors as a potential predictive tool in women with suspected preeclampsia.

OBJECTIVES: To investigate whether longitudinal changes of angiogenic factors (AF) sFlt-1, PlGF, and the sFlt-1/PlGF ratio, measured following identification of symptoms of preeclampsia (PE), could provide complementary information to the isolated measurements used in current clinical practice. STUDY DESIGN: Retrospective observational study. Sixty women with suspected PE and two AF results measured before gestational week (GW) 34 were included. Daily variation (DV) of AF was calculated from delta values and days elapsed between measurements. Through ROC analysis, the predictive performance of DV for PE-related events was estimated. Kaplan-Meier survival curves resulting from applying cutoff values were assessed. RESULTS: The sFlt-1, PlGF, and sFlt-1/PlGF ratio baseline levels showed significant differences between women without PE and women who developed early-onset PE (P < 0.001). DV of sFlt-1 and sFlt-1/PlGF ratio increased according to the severity of PE, showing significant differences in both pairs of groups compared (p < 0.001), so they were selected as potential predictors. Higher AUC values resulting from ROC analysis were 0.78 for early-onset PE, 0.88 for early-onset severe PE, 0.79 for occurrence of adverse maternal outcomes, and 0.89 for delivery before 37 GW, with sensitivity and specificity values higher than 0.71 and 0.80, respectively. The Kaplan-Meier analysis yielded significantly different curves (log-rank < 0.05), with shorter time-to-delivery as DV increased. CONCLUSION: Our results support the existence of a correlation between a progressive PlGF and sFlt-1 imbalance and a more aggressive clinical course of PE, detectable from the finding of PE symptoms. Its monitoring could be a useful predictive tool in women with suspected PE.

Main applications of point-of-care ultrasound in palliative care.

Combined with a physical examination, clinical ultrasound offers a valuable complement that can help guide clinical decision-making. In various medical and surgical specialties, it is increasingly used for diagnostic and therapeutic purposes. Due to recent technological advances, smaller and more affordable ultrasound machines are now being developed for use in home hospice care. The purpose of this paper is to describe how clinical ultrasound may be applied in Palliative Care, where it can be a valuable tool to assist the clinician in making better clinical decisions and to assist in accurately guiding palliative procedures. Furthermore, it can be used to identify unnecessary hospitalizations and prevent them from occurring. Training programs with specific objectives are necessary to implement clinical ultrasound in Palliative Care, as well as defining learning curves and promoting alliances with scientific societies that recognize the teaching, care and research trajectory for accreditation of competencies.

Pancreas fat content, insulin homeostasis and circulating endothelial microparticles in male essential hypertensive patients.

The pancreas fat content has been poorly investigated in essential hypertension. The authors aim to relate pancreas and liver fat content with parameters measuring insulin resistance, beta-cell function and also with markers of endothelial dysfunction and platelet or endothelial cell destruction. The authors studied a group of 40 male hypertensive patients with well-controlled blood pressure, maintaining a stable weight, and having not changed their medication during the last year. Pancreas fat content was correlated with HOMA-IR (r = .616, p < .001), HOMA-S (r = -.439, p < .005), beta cell function parameter (r = .457, p < .005), and QUICKI (r = .412, p < .01), whereas liver fat was not patients in the highest quartile of pancreas fat content had more circulating endothelial microparticles than patients in the other quartiles (median 129 [94.3-200] vs. 60.9 [49.4-88.8], p = .002). However, patients in the highest quartile of the pancreas fat content distribution did not differ from the lowest in hyperemic response after ischemia nor circulating platelet microparticles count. Liver fat content was not related to any of the parameters studied. In a multivariate stepwise binary logistic regression analysis (Wald Method) circulating endothelial microparticles remain significantly associated with pancreas fat content after adjusting for confounding factors, such as tobacco, diabetes mellitus, hypercholesterolemia, or metabolic syndrome. Our results reflect that in essential hypertension, pancreas fat content is superior to liver fat to study beta-cell functionality and insulin resistance. Moreover, the authors described for the first time that pancreas fat content is related to endothelial cell destruction. Further studies are needed to confirm this point.

Prognostic Significance of Lung and Cava Vein Ultrasound in Elderly Patients Admitted for Acute Heart Failure: PROFUND-IC Registry Analysis.

Introduction: Heart failure is an extremely prevalent disease in the elderly population of the world. Most patients present signs and symptoms of decompensation of the disease due to worsening congestion. This congestion has been clinically assessed through clinical signs and symptoms and complementary imaging tests, such as chest radiography. Recently, pulmonary and inferior vena cava ultrasound has been shown to be useful in assessing congestion but its prognostic significance in elderly patients has been less well evaluated. Objectives: This study aims to compare the clinical and radiological characteristics and predictive values for mortality in patients admitted for heart failure through the determination of B lines by lung ultrasound and the degree of collapsibility of the inferior vena cava (IVC). Secondarily, the study aims to assess the prediction of 30-day mortality based on the diameter of the IVC by means of the ROC curve. Methods: This is an observational cohort study based on data collected in the PROFUND-IC study, a nationwide multicentric registry of patients admitted with decompensated heart failure. Data were collected from these patients between October 2020 and April 2022. Results: A total of 482 patients were entered into the PROFUND-IC registry between October 2020 and April 2022. Bedside clinical ultrasound was performed during admission in 301 patients (64.3%). The number of patients with more than 6 B-lines on lung ultrasound amounted to 194 (66%). Statistically significant differences in 30-day mortality (22.1% vs. 9.2%; p = 0.01) were found in these patients. The sum of patients with IVC collapsibility of less than 50% amounted to 195 (67%). Regarding prognostic value, collapsibility data were significant for the number of admissions in the last year (12.5% vs. 5.5%; p = 0.04), in-hospital mortality (10.1% vs. 3.3%, p = 0.04) and 30-day mortality (22.6% vs. 8.1%; p < 0.01), but not for readmissions. Regarding the prognostic value of IVC diameter for 30-day mortality, the area under the ROC curve (AUC) was 0.73, with a p < 0.01. The curve cut-off point with the highest sensitivity (70%) and specificity (70.3%) was for an IVC value of 22.5 mm. In the logistic regression analysis, we observed that the variable most associated with patient survival at 30 days was the presence of a collapsible inferior vena cava, with more than 50% OR 0.359 (CI 0.139−0.926; p = 0.034). Conclusions: The subgroups of patients analyzed with more than six B lines per field and IVC collapsibility less than or equal to 50%, as measured by clinical ultrasound, had higher 30-day mortality rates than patients who did not fall into these subgroups. IVC diameter may be a good independent predictor of 30-day mortality in patients with decompensated heart failure. Comparing both ultrasound variables, it seems that in our population, the assessment of the inferior vena cava may be more associated with short-term prognosis than the pulmonary congestion variables assessed by B lines.

PostCOVID effect on endothelial function in hypertensive patients: A new research opportunity.

SARS-CoV-2 is causing devastation both in human lives and economic resources. When the world seems to start overcoming the pandemics scourge, the threat of long-term complications of COVID-19 is rising. Reports show that some of these long-term effects may contribute to the main cause of morbimortality worldwide: the vascular diseases. Given the evidence of damage in the endothelial cells due to SARS-CoV-2 and that endothelial dysfunction precedes the development of arteriosclerosis, the authors propose to measure endothelial function around 6-12 months after acute disease in hypertensive patients, especially if they have other cardiovascular risk factors or overt vascular disease. The methods the authors propose are cost-effective and can be made available to any hypertension unit. These methods could be the "in vivo" assessment of endothelial function by flow mediated vasodilatation after ischemia by Laser-Doppler flowmetry and the measurement of plasma free circulating DNA and microparticles of endothelial origin.

Basal insulin analogues in people with diabetes and chronic kidney disease.

BACKGROUND: Diabetic kidney disease is the leading cause of chronic kidney disease (CKD) and end-stage kidney disease (ESKD) worldwide. ESKD has a high prevalence in patients with diabetes mellitus (DM). CKD increases the chances of hypoglycaemia by different mechanisms, causes insulin resistance and a decrease in insulin metabolism. Both the "Kidney Disease: Improving Global Outcomes" (KDIGO) and "American Diabetes Association" (ADA) guidelines recommend the use of insulin as part of treatment, but the type of basal insulin is not specified. METHODS: We reviewed the literature to determine whether first- and second-generation basal insulins are effective and safe in CKD patients. We reviewed specific pivotal studies conducted by pharmaceutical laboratories, as well as independent studies. CONCLUSIONS: Basal insulins are safe and effective in patients with CKD and diabetes mellitus but we do not have specific studies. Given that CKD is one of the main complications of type 2 DM, and insulin specific treatment in the final stages, the absence of studies is striking. Real-life data are also important since trials such as pivotal studies do not fully represent actual patients. Treatment should be individualized until we have specific trials in this type of population.

Cerebrovascular Disease and Statins.

Elevated low-density lipoprotein-cholesterol (LDL-C) is a causal factor for the development of atherosclerotic cardiovascular disease (ASCVD); accordingly, LDL-C lowering is associated with a decreased risk of progression of atherosclerotic plaques and development of complications. Currently, statins play a central role in any ASCVD management and prevention strategies, in relation to their lipid-lowering action and potentially to pleiotropic effects. After coronary artery disease, stroke is the most frequent cause of ASCVD mortality and the leading cause of acquired disability, a major public health problem. There is often a tendency to aggregate all types of stroke (atherothrombotic, cardioembolic, and haemorrhagic), which have, however, different causes and pathophysiology, what may lead to bias when interpreting the results of the studies. Survivors of a first atherothrombotic ischemic stroke are at high risk for coronary events, recurrent stroke, and vascular death. Although epidemiological studies show a weak relationship between cholesterol levels and cerebrovascular disease as a whole compared with other ASCVD types, statin intervention studies have demonstrated a decrease in the risk of stroke in patients with atherosclerosis of other territories and a decrease in all cardiovascular events in patients who have had a stroke. The Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) trial demonstrated the benefit of high doses of atorvastatin in the secondary prevention of ischemic stroke. In this review, we discuss the evidence, use and recommendations of statins in the primary and secondary prevention of stroke, and their role in other scenarios such as the acute phase of ischemic stroke, cerebral hemorrhage, cardioembolic stroke, small vessel disease, and cognitive impairment.

Prediction Accuracy of Serial Lung Ultrasound in COVID-19 Hospitalized Patients (Pred-Echovid Study).

The value of serial lung ultrasound (LUS) in patients with COVID-19 is not well defined. In this multicenter prospective observational study, we aimed to assess the prognostic accuracy of serial LUS in patients admitted to hospital due to COVID-19. The serial LUS protocol included two examinations (0-48 h and 72-96 h after admission) using a 10-zones sequence, and a 0 to 5 severity score. Primary combined endpoint was death or the need for invasive mechanical ventilation. Calibration (Hosmer-Lemeshow test and calibration curves), and discrimination power (area under the ROC curve) of both ultrasound exams (SCORE1 and 2), and their difference (DIFFERENTIAL-SCORE) were performed. A total of 469 patients (54.2% women, median age 60 years) were included. The primary endpoint occurred in 51 patients (10.9%). Probability risk tertiles of SCORE1 and SCORE2 (0-11 points, 12-24 points, and ≥25 points) obtained a high calibration. SCORE-2 showed a higher discrimination power than SCORE-1 (AUC 0.72 (0.58-0.85) vs. 0.61 (0.52-0.7)). The DIFFERENTIAL-SCORE showed a higher discrimination power than SCORE-1 and SCORE-2 (AUC 0.78 (0.66-0.9)). An algorithm for clinical decision-making is proposed. Serial lung ultrasound performing two examinations during the first days of hospitalization is an accurate strategy for predicting clinical deterioration of patients with COVID-19.

[Sugar and cardiovascular disease]. / Azúcar y enfermedades cardiovasculares.

Cardiovascular diseases are the leading cause of death in the Spanish population and may be a relationship between the prevalence of these and excessive sugar consumption. In recent years, researchers have focused on the properties of these nutrients. Although there are many studies examining this association, the results are not unanimous. In any case there is sufficient basis for designing public health strategies in order to reduce the consumption of sugary drinks as part of a healthy lifestyle. Therefore, the question we address is: sugar intake in abundant amounts, is associated with a higher risk of cardiovascular disease? We use as the focus of the discussion SAFO analysis model.

Las enfermedades cardiovasculares constituyen la principal causa de muerte en la población española y podría existir una relación entre la prevalencia de las mismas y el consumo excesivo de azúcar. En estos últimos años, los investigadores se han centrado en las propiedades de estos nutrientes. Aunque existen muchos estudios que analizan dicha asociación, los resultados no son unánimes. En cualquier caso, existe fundamento suficiente para diseñar estrategias de salud pública de cara a reducir el consumo de bebidas azucaradas, como parte de un estilo de vida saludable. Por lo tanto, la cuestión que abordamos es: ¿la ingesta de azúcar, en cuantía abundante, se asocia un mayor riesgo de padecer enfermedad cardiovascular? Para ello utilizamos como eje de la discusión el modelo de análisis DAFO.
