RESUMEN
Objectives: Recently, desert dust in Europe has been recognized as a cardiovascular health problem. In Spain, desert dust inflows in recent years have been associated with worsening air quality. The present study examines whether desert dust events are related to the incidence of acute coronary syndrome (ACS) in patients under 55 years of age. Methods: Data from 2416 consecutive patients admitted to a tertiary hospital due to ACS were prospectively analyzed. A case-crossover time-stratified design using Poisson conditional regression models was applied to estimate the impact of desert dust events involving particulate matter concentrations of an aerodynamic diameter <10 µm (PM10) on the incidence of ACS in patients under 55 years of age. Results: Desert dust intrusion on days 0 to 5 before ACS onset showed no significant association with the incidence of ACS in patients under 55 years of age. The incidence rate ratios of PM10 concentrations 1, 2, 3, 3, 4, and 5 days before ACS onset (for changes of 10 µg/m3) were 1.02 (95% CI 0.97-1.1; p = 0.41), 1.01 (95% CI 0.96-1.07; p = 0.66), 0.99 (95% CI 0.94-1.05; p = 0.78), 0.96 (95% CI 0.9-1.02; p = 0.18), and 0.97 (95% CI 0.91-1.04; p = 0.41). Conclusions: Our findings suggest that desert dust is unlikely to be related to the incidence of ACS in patients under 55 years of age.
RESUMEN
(1) Introduction: Dilated cardiomyopathy (DCM) mainly affects young individuals and is the main indication of heart transplantation. The variant c.77T>C (p.Val26Ala) of the gene coding for emerin (EMD) in chromosome Xq28 has been catalogued as a pathogenic variant for the development of DCM, exhibiting an X-linked inheritance pattern. (2) Methods: A retrospective study was conducted covering the period 2015-2023 in patients with DCM of genetic origin. The primary endpoint was patient age at onset of the first composite major cardiac event, in the form of a first episode of heart failure, malignant ventricular arrhythmia, or end-stage heart failure, according to the presence of truncating variant in titin gene (TTNtv) versus the p.Val26Ala mutation in the EMD protein. (3) Results: A total of 31 and 22 patients were included in the EMD group and TTNtv group, respectively. The primary endpoint was significantly higher in the EMD group, with a hazard ratio of 4.16 (95% confidence interval: 1.83-9.46; p = 0.001). At 55 years of age, all the patients in the EMD group had already presented heart failure, nine presented malignant ventricular arrhythmia (29%), and 13 required heart transplantation (42%). (4) Conclusions: DCM secondary to the c.77T>C (p.Val26Ala) mutation in the EMD gene is associated to an increased risk of major cardiac events compared to patients with DCM due to TTNtv, with a large proportion of transplanted patients in the fifth decade of life.
RESUMEN
Background. Oxidative stress has been involved in the pathogenesis of rheumatoid arthritis (RA). The serum malondialdehyde (MDA) level is a reliable biomarker of oxidative stress status. In the present work, we aimed to analyze how a comprehensive characterization of the disease characteristics in RA, including a lipid profile, insulin resistance, and subclinical atherosclerosis, relates to serum MDA levels. Methods. In a cross-sectional study that included 430 RA patients, serum MDA levels were evaluated. Multivariable analysis was performed to examine the relationship of MDA with disease activity scores and disease characteristics, including subclinical carotid atherosclerosis, a comprehensive lipid molecule profile, and indices of insulin resistance and beta cell function indices. Results. The erythrocyte sedimentation rate (ESR) showed a significant and positive relationship with MDA. However, this did not occur for other acute phase reactants such as C-reactive protein or interleukin-6. Although the DAS28-ESR score (Disease Activity Score in 28 joints) had a positive and significant association with MDA serum levels, other disease activity scores that do not use the erythrocyte sedimentation rate in their formula did not show a significant relationship with MDA. Other disease characteristics, such as disease duration and the existence of rheumatoid factor and antibodies against citrullinated protein, were not related to serum MDA levels. This also occurred for lipid profiles, insulin resistance indices, and subclinical carotid atherosclerosis, for which no associations with circulating MDA were found. Conclusions. The disease characteristics are not related to circulating MDA levels in patients with RA.
RESUMEN
Severe alcoholic hepatitis is the most lethal complication in alcohol dependent patients. The concurrence of infections in these patients is very frequent. Both produce a systemic inflammatory response syndrome (SIRS), secondary to intense release of inflammatory cytokines, which can complicate the diagnosis. In our study, Interleukin (IL)-6 and IL-10 levels are higher in patients with SIRS (p<0.001 and p = 0.033, respectively). IL-4, IL-6, Interferon-gamma (IFNγ), Tumor necrosis factor alpha (TNFα) and IL-17 levels correlate with liver function, as estimated by MELD-Na (p = 0.018, p = 0.008, p = 0.009, p = 0.016 and p = 0.006, respectively). Malondialdehyde (MDA), a product of lipid peroxidation and marker of cell damage, also correlates with liver function (p = 0.002), but not with SIRS or infections. Only elevated IL-6 correlates independently with the presence of infections (RR=1.023 IC 95% 1.000-1.047), so it may be useful for the correct diagnosis in these patients. Values greater than 30 pg/mL have a sensitivity: 86.7% and specificity: 94.7% for the diagnosis of infections.

OBJECTIVES: To analyze whether urinary catheterization in a hospital emergency department (ED) affects short-term prognosis in patients with acute heart failure (AHF). MATERIAL AND METHODS: We prospectively recorded baseline and other clinical data in a consecutive cohort of ED patients treated for AHF. Crude and adjusted associations were calculated between catheterization and a primary composite outcome (30-day readmission for AHF and/or death) and secondary outcomes (in-hospital mortality, urinary tract infection [UTI], and duration of hospital stay.). RESULTS: Nine hundred ninety-one patients were admitted for AHF. The mean (SD) age was 66 (10.5) years; 71% were women. Catheterization was required for 29.2% in the ED. The primary composite outcome was observed in 7.7% of the patients who were not catheterized and 12.8% of the catheterized patients (P = .02). In-hospital mortality occurred in 5.9% and 9.7% of non-catheterized and catheterized patients, respectively (P = .04), and UTIs occurred in 19.1% and 26.6% (P = .01). Twelve of the non-catheterized patients (1.7%) were readmitted for AHF (vs 11 (3.8%) of the catheterized patients (P = .06), and there were no differences between the groups in hospital stay (11 vs 10.9 days, P = .78). In the adjusted analysis of associations between catheterization and the primary outcome the odds and hazard ratios (OR and HR, respectively) were OR, 1.7 (95% CI, 1.1-2.7) (P = .02) and HR, 1.6 (95% CI, 1.1-2.5) (P = .03). For secondary outcomes, significant associations emerged between catheterization and UTIs (OR, 1.8 [95% CI, 1.1-2.2]; P = .008) and readmission for AHF (OR, 2.9 [95% CI, 1.2-7.3]; P = .02). CONCLUSION: Routine insertion of a urinary catheter in patients with AHF in the ED is associated with worse 30-day clinical outcomes.
OBJETIVO: Analizar si el sondaje vesical (SV) rutinario en un servicio de urgencias hospitalario (SUH) de pacientes diagnosticados de insuficiencia cardiaca aguda (ICA) está asociado con la evolución a corto plazo. METODO: Se recogieron prospectivamente datos basales y clínicos de una cohorte de pacientes consecutivos que ingresaron por ICA. Se analizó la asociación cruda y ajustada del SV con el evento combinado de muerte o reingreso por insuficiencia cardiaca a 30 días (objetivo primario), así como mortalidad intrahospitalaria, infección del tracto urinario (ITU) y estancia hospitalaria (objetivos secundarios). RESULTADOS: Se incluyeron 991 pacientes hospitalizados por ICA, la edad media fue de 66 años (DE 10,5) y el 71% fueron mujeres. Un 29,2% de los pacientes requirieron SV en el SUH. El evento combinado fue del 7,7% para el grupo no SV y 12,8% para grupo SV (p = 0,02); mortalidad intrahospitalaria fue del 5,9% en el grupo no SV y 9,7% en el grupo SV (p = 0,04); se diagnosticó ITU en el 19,1% de pacientes en el grupo no SV y en el 26,6% en el grupo SV (p = 0,01). A 30 días, 12 pacientes (1,7%) reingresaron por insuficiencia cardiaca en el grupo no SV versus 11 (3,8%) pacientes en el grupo SV (p = 0,06). No hubo diferencias en la estancia hospitalaria (11 versus 10,9 días); p = 0,78). En el análisis ajustado, el SV se asoció con el objetivo primario; [OR = 1,7 (IC 95%: 1,1-2,7; p = 0,02); HR = 1,6 (IC 95%: 1,1-2,5; p = 0,03)]; con la ITU (OR = 1,8; IC 95%: 1,12,2; p = 0,008) y con el reingreso por insuficiencia cardiaca (OR = 2,9; IC 95%: 1,2-7,3; p = 0,02). CONCLUSIONES: La inserción rutinaria del SV en el SUH en pacientes con ICA se asoció a peores resultados clínicos a los 30 días.

Systemic sclerosis (SSc) is a chronic disease characterized by vasculopathy with the involvement of dysfunctional microcirculatory vessels. Features of the disease include progressive fibrosis of the skin and internal organs and systemic inflammation characterized by the presence of circulating autoantibodies and proinflammatory cytokines. Furthermore, macrovascular disease and atherosclerosis are more common in patients with SSc than in the general population. Oxidative stress plays a crucial role in the development of several processes, including endothelial dysfunction, cancer, inflammation, and atherogenesis. Malondialdehyde (MDA) is a well-established marker of oxidative stress. In this work, we have analyzed the relationship between serum MDA levels and clinical, laboratory, and vascular characteristics in a well-characterized cohort of 53 patients with SSc. A multivariable analysis was performed to study the relationship between circulating MDA and disease characteristics in patients with SSc. Cardiovascular assessment was also performed, including ultrasonography of the carotid and aorta, and echocardiography. MDA showed a significant and positive relationship with the serum levels of lipid profile molecules such as total cholesterol (ß coefficient = 0.006 (95% CI: 0.0004 to 0.01), nmol/mL, p = 0.037) and LDL cholesterol (ß coefficient = 0.008 (95% CI: 0.001 to 0.01) nmol/mL, p = 0.017). On the contrary, most manifestations of the disease, including skin, lung, and joint involvement, as well as the presence of digital ulcers, were not related to MDA. However, high MDA levels were significantly and independently associated with lower ventricular ejection fraction after adjustment for covariates (ß coefficient = -0.04 (95% CI: -0.06 to -0.02), nmol/mL, p = 0.001). In conclusion, serum MDA levels were related to higher levels of total and LDL cholesterol and a lower left ventricular ejection fraction in patients with SSc. MDA could serve as a potential biomarker of dyslipidemia and heart failure in SSc.
RESUMEN
AIMS: Chronic obstructive pulmonary disease (COPD) is an important comorbidity in heart failure. The MIMO trial showed that patients with acute cardiogenic pulmonary edema (ACPE) treated with midazolam had fewer serious adverse events than those treated with morphine. In this post hoc analysis, we examined whether the presence/ absence of COPD modifies the reduced risk of midazolam over morphine. METHODS: Patients >18 years old clinically diagnosed with ACPE and with dyspnea and anxiety were randomized (1:1) at emergency department arrival to receive either intravenous midazolam or morphine. In this post hoc analysis, we calculated the relative risk (RR) of serious adverse events in patients with and without COPD. Calculating the CochranMantel-Haenszel interaction test, we evaluated if COPD modified the reduced risk of serious adverse events in the midazolam arm compared to morphine. RESULTS: Overall, 25 (22.5%) of the 111 patients randomized had a history of COPD. Patients with COPD were more commonly men with a history of previous episodes of heart failure, than participants without COPD. In the COPD group, the RR for the incidence of serious adverse events in the midazolam versus morphine arm was 0.36 (95%CI, 0.1-1.46). In the group without COPD, the RR was 0.44 (95%CI, 0.22-0.91). The presence of COPD did not modify the reduced risk of serious adverse events in the midazolam arm compared to morphine (p for interaction =0.79). CONCLUSIONS: The reduced risk of serious adverse events in the midazolam group compared with morphine is similar in patients with and without COPD.
RESUMEN
AIMS: The main objective of this study is to determine whether exposure to Saharan dust causes airway inflammation and oxidative stress in patients with stable chronic heart failure (HF) and a left ventricular ejection fraction of less than 40%. METHODS: A longitudinal study design is used, involving the inclusion of 40 patients with stable chronic HF and a left ventricular ejection fraction of less than 40%. Four sputum samplings will be taken from each patient, with one sampling taken each week over four consecutive weeks. The sputum samples will be used to analyze the degree of inflammation and oxidative stress. Air quality monitoring stations will be used to analyze the particulate matter (PM) exposure of each patient. The intrusion of desert dust will be identified using meteorological models. There will be 160 scheduled samplings in 40 patients with chronic HF. Mixed regression models will be used to assess the influence of the concentrations of PM (from the episodes of desert dust) upon the airway inflammation and oxidative stress markers. CONCLUSION: The results of this study will test the hypothesis that exposure to high concentrations of Saharan dust affects the normal function of the respiratory epithelium due to the imbalance between the production of free radicals and antioxidant enzymes, thus causing increased pulmonary inflammation and oxidative stress in patients with HF that in turn may facilitate decompensations of their background disease condition.
RESUMEN
Malondialdehyde (MDA) is a marker of oxidative stress and antioxidant status. Oxidative stress has been observed to be increased in systemic lupus erythematosus (SLE). Some studies have shown that MDA is upregulated in SLE compared to controls. However, the literature lacks reports regarding the relationship of MDA to disease manifestations. This is relevant since SLE is a multisystemic disease which may affect virtually any organ in the body. In this study, we set out to analyze how MDA serum levels are associated with disease expression in a large series of SLE patients who were fully characterized in clinical and laboratory terms. A total of 284 patients with SLE were recruited. Serum levels of MDA, and the activity (SLEDAI), severity (Katz) and damage index (SLICC-DI) scores, full lipid profile, and carotid subclinical atherosclerosis were assessed. In addition, a full characterization of the complement system was performed in SLE patients' samples. Multivariable linear regression analysis was executed to study the relationship between clinical and laboratory disease characteristics and MDA. A statistically significant negative relationship was found between disease duration and MDA. In contrast, the presence of anti-nucleosome antibodies was positively associated with MDA. Regarding the SLICC-DI areas, both the musculoskeletal domain and the cutaneous domain were significantly related to higher serum MDA values. Furthermore, after adjustment for confounding factors, lower levels of the classical complement pathway, which denotes activation, were associated with higher serum levels of MDA. In conclusion, cumulative musculoskeletal and skin damage in SLE patients is associated with superior serum levels of MDA. In addition, activation of the complement system is also related to higher circulating MDA levels.

In recent years, the terms sarcopenia, sarcopenic obesity, and osteosarcopenic obesity (OSO) were coined to define a situation in elderly people strongly associated with frailty and increased mortality. Possibly, a complex interplay of several hormones and cytokines are involved in its development. Ongoing research detected that OSO may occur at any age and in several conditions. The prevalence of OSO in alcoholism was poorly analyzed. The aim of this study was to analyze the prevalence of OSO in alcoholism and its relationship with proinflammatory cytokines and/or common complications of alcoholism, such as cirrhosis, cancer, or vascular disease. We included 115 patients with alcoholic use disorder. Body composition analysis was performed by double X-ray absorptiometry. Handgrip strength was recorded using a dynamometer. We assessed liver function according to Child's classification, and determined serum levels of proinflammatory cytokines (TNF-α, IL-6, IL-8), routine laboratory variables, and vitamin D. People with alcoholic use disorder showed a high prevalence of OSO, especially regarding OSO obesity (60%), OSO osteopenia (55.65%), and OSO lean mass (60.17%). OSO handgrip was closely, independently, related to the presence of vascular calcification (χ2 = 17.00; p < 0.001). OSO handgrip was related to several proinflammatory cytokines and vitamin D. Vitamin D deficiency kept a close correlation with OSO handgrip (rho = -0.54, p < 0.001). Therefore, among people with alcohol use disorder, OSO prevalence was high. OSO handgrip is related to serum proinflammatory cytokine levels supporting the possible pathogenetic role of these cytokines on OSO development. Vitamin D deficiency is related to OSO handgrip suggesting its pathogenetic involvement in sarcopenia in patients with alcohol use disorder. The close association between OSO handgrip and vascular calcification is clinically relevant and suggests that OSO handgrip may constitute a prognostic tool in these patients.

Introducción. El factor neurotrófico derivado del cerebro(BDNF) es una neurotrofina que se ha relacionado con la hipótesis del neurodesarrollo de la esquizofrenia. Varios estudios confirman que los niveles de BDNF en el primer episodio psicótico (PEP) son más bajos que en los controles sanos. Sin embargo, los datos al respecto de la evolución de los niveles tras un PEP y el valor pronóstico de dichos niveles son controvertidos. Método. Se compararon los niveles séricos de BDNF al ingreso de 28 pacientes hospitalizados con PEP con 28controles sanos. También se midió el BDNF al momento del alta, a los tres, seis, nueve y doce meses. Los niveles de BDNF se presentan en ng/ml. Se buscó correlación con la sintomatología psicótica medida con la Escala de Síndrome Positivo y Negativo (PANSS) y se evaluó en valor pronóstico de los niveles basales para predecir mala funcionalidad (medida por la Evaluación Global del Funcionamiento) y/o recaída, así como el diagnóstico ulterior de un trastorno psicótico crónico. Resultados. Al ingreso, los niveles de BDNF de los pacientes fueron significativamente más bajos que los niveles de los controles sanos (18,52±4,51 vs. 26,55±3,22, p<0,001). Al altalos niveles de PEP aumentaron hasta niveles de los controles sanos (25,95±3,96 vs. 26,55±3,22, p=0,539). En las siguientes determinaciones, los niveles de BDNF en PEP disminuyeron, alcanzando los valores de ingreso y siendo significativamente más bajos que los controles sanos y los niveles al alta(pacientes: tres meses: 19,68±3,88; seis meses: 19,02±4,13;nueve meses: 17,64±5,24; doce meses:17,51±3,45 vs. controles sanos: 26,55±3,22, todos p<0,001). Se encontró una correlación negativa entre el BDNF al ingreso y las puntuaciones de la subescala de síntomas negativos de la PANSS con una tendencia hacia la significación (r=-0,303, p=0,093). ...

Introduction. The brain-derived neurotrophic factor(BDNF) is a neurotrophin that has been linked to the schizophrenia neurodevelopmental hypothesis. Several studiesconfirm that the BDNF levels in first-episode psychosis (FEP)are lower than in healthy controls (HC). However, data aboutevolution of BDNF levels after a FEP and about the prognostic value of these levels are controversial. Method. Serum BDNF levels at admission of 28 inpatients with FEP were compared with 28 HC. BDNF was also measured at discharge, three, six, nine and twelve months. BDNF levels are presented in ng/ml. We looked for correlation of BDNF levels with the psychotic symptomatology measuredwith the Positive and Negative Syndrome Scale (PANSS) andalso the prognostic value of basal levels was evaluated topredict poor functionality (measured by the Global Assessment of Functioning) and/or relapse, as well as the subsequent diagnosis of a chronic psychotic disorder. Results. At admission, patients BDNF levels were significantly lower than HC levels (18.52±4.51 vs. 26.55±3.22,p<0.001). At discharge FEP levels increase until HC levels(25.95±3.96 vs. 26.55±3.22, p=0,539). Upon the following determinations, BDNF FEP levels decreased, reaching the admission values, and being significantly lower than the HC andthe levels at discharge (patients: three months: 19.68±3.88;six months: 19.02±4.13; nine months: 17.64±5.24; twelve months: 17.51±3.45 vs. HC: 26.55±3.22, all p<0.001). A negative correlation was found between admission BDNF levels and the PANSS negative symptoms subscale score with a trend towards significance (r=-0.303, p=0.093). BDNF levels at admission of patients with por functionality and/orrelapse at 12 months were lower than BDNF levels of patients with goof functionality and without relapse, this difference had a trend towards significance. (15.38±4.72 vs.19.57±4.06; p=0.071). (AU)

Objective: Heavy alcohol consumption causes several organic complications, including vessel wall calcification. Vascular damage may be involved in the development of brain atrophy and cognitive impairment. Recently, sclerostin (whose levels may be altered in alcoholics) has emerged as a major vascular risk factor. The objective of the present study is to analyze the prevalence of vascular calcifications in alcoholics, and the relationships of these lesions with brain atrophy, as well as the role of sclerostin on these alterations. Patients and methods: A total of 299 heavy drinkers and 32 controls were included. Patients underwent cranial computed tomography, and several indices related to brain atrophy were calculated. In addition, patients and controls underwent plain radiography and were evaluated for the presence or absence of vascular calcium deposits, cardiovascular risk factors, liver function, alcohol intake, serum sclerostin, and routine laboratory variables. Results: A total of 145 (48.47%) patients showed vascular calcium deposits, a proportion significantly higher than that observed in controls (χ2 = 16.31; p < 0.001). Vascular calcium deposits were associated with age (t = 6.57; p < 0.001), hypertension (t = 5.49; p < 0.001), daily ethanol ingestion (Z = 2.18; p = 0.029), duration of alcohol consumption (Z = 3.03; p = 0.002), obesity (χ2 = 4.65; p = 0.031), total cholesterol (Z = 2.04; p = 0.041), triglycerides (Z = 2.05; p = 0.04), and sclerostin levels (Z = 2.64; p = 0.008). Calcium deposits were significantly related to Bifrontal index (Z = 2.20; p = 0.028) and Evans index (Z = 2.25; p = 0.025). Serum sclerostin levels were related to subcortical brain atrophy, assessed by cella media index (Z = 2.43; p = 0.015) and Huckmann index (ρ = 0.204; p = 0.024). Logistic regression analyses disclosed that sclerostin was the only variable independently related to brain atrophy assessed by altered cella media index. Sclerostin was also related to the presence of vascular calcifications, although this relationship was displaced by age if this variable was also included. Conclusion: Prevalence of vascular calcification in alcoholics is very high. Vascular calcium deposits are related to brain atrophy. Serum sclerostin is strongly related to brain shrinkage and also shows a significant relationship with vascular calcifications, only displaced by advanced age.
RESUMEN
OBJECTIVES: The midazolam vs morphine (MIMO) trial showed that patients treated with midazolam had fewer serious adverse events than those treated with morphine. In many patients with acute pulmonary edema, the left ventricular ejection fraction (LVEF) is preserved, at 50% or higher. We aimed to determine whether left ventricular (LV) systolic dysfunction (D), defined by an LVEF of less than 50%, modifies the protective effect of midazolam vs morphine. MATERIAL AND METHODS: The MIMO trial randomized 111 patients with acute pulmonary edema to receive intravenous midazolam in 1-mg doses to a maximum of 3 mg (n = 55) or morphine in 2- to 4-mg doses to a maximum of 8 mg (n= 56). We calculated the relative risk (RR) for a serious adverse event in patients with and without systolic LVD. RESULTS: LVEF was preserved in 84 (75.7%) of the patients with acute pulmonary edema. In patients with systolic LVD, 4 patients (26.9%) in the midazolam arm vs 6 (50%) in the morphine arm developed serious adverse events (RR, 0.53; 95% CI, 0.2-1.4). In patients without systolic LVD, 6 patients (15%) in the midazolam arm vs 18 (40.9%) in the morphine arm experienced such events (RR, 0.37; 95% CI, 0.16-0.83). The presence of systolic LVD did not modify the protective effect of midazolam on serious adverse effects (P=.57). CONCLUSION: The effect of midazolam vs morphine in protecting against the development of serious adverse events or death is similar in patients with and without systolic LVD.
OBJETIVO: El ensayo clínico MIMO demostró que los pacientes con edema agudo de pulmón (EAP) tratados con midazolam tenían menos eventos adversos graves (EAG) que los tratados con morfina. Muchos pacientes con EAP tienen fracción de eyección del ventrículo izquierdo (FEVI) preservada ($ 50%). El objetivo fue conocer si la disfunción sistólica ventricular izquierda (DSVI) (fracción eyección ventrículo izquierdo 50%) modifica el efecto protector del midazolam frente a la morfina. METODO: El estudio MIMO asignó al azar 111 pacientes con EAP a tratamiento con midazolam (dosis de 1 mg intravenosa, hasta una dosis máxima de 3 mg, n = 55) o morfina (dosis de 2-4 mg, hasta una dosis máxima de 8 mg, n = 56). Se calculó el riesgo relativo (RR) de padecer un EAG en pacientes con y sin DSVI. RESULTADOS: La FEVI preservada estuvo presente en 84 (75,7%) pacientes con EAP. En el grupo con DSVI, 4 pacientes (26,9%) en el brazo midazolam frente a 6 (50%) en el brazo morfina presentaron EAG (RR = 0,53; IC 95: 0,2-1,4). En el grupo sin DSVI 6 pacientes (15%) del brazo midazolam frente a 18 (40,9%) del brazo morfina presentaron EAG (RR = 0,37; IC 95: 0,16-0,83). La DSVI no modificó el efecto protector del midazolam en la aparición de EAG con respecto a la morfina (p = 0,57). CONCLUSIONES: En pacientes con EAP el efecto protector del midazolam sobre la morfina en la aparición de EAG y EAG o muerte fue similar en pacientes con y sin DSVI.

BACKGROUND AND IMPORTANCE: The MIMO clinical trial showed that patients with acute cardiogenic pulmonary edema (ACPE) treated with midazolam had fewer serious adverse events than those treated with morphine. Atrial fibrillation (AF) is a common comorbidity in heart failure and affects patient's outcome. OBJECTIVE: The primary endpoint of this substudy is to know if AF modified the reduced risk of serious adverse events in the midazolam arm compared to morphine. The first secondary endpoint is to know if AF modified the reduced risk of serious adverse events or death at 30 days in the midazolam arm. The second secondary objective of this substudy is to analyze whether AF modified the reduced risk of midazolam against morphine on the total number of serious adverse events per patient. DESIGN: We conducted a secondary analysis of the MIMO trial. Patients more than 18 years old clinically diagnosed with ACPE and with dyspnea and anxiety were randomized (1:1) at emergency department arrival to receive either intravenous midazolam or morphine. OUTCOME MEASURES AND ANALYSIS: In this post hoc analysis, we calculated the relative risk (RR) of serious adverse events in patients with and without AF. Calculating the Cochran-Mantel-Haenszel interaction test, we evaluated if AF modified the reduced risk of serious adverse events in the midazolam arm compared to morphine. MAIN RESULTS: One hundred eleven patients (median = 78.9 years; IQR, 72.3-83.7; women, 52.2%) were randomized in the MIMO trial, 55 to receive midazolam and 56 to morphine. All randomized patients received the assigned drug and there were no losses to follow-up. Forty-four patients (39.6%) had AF. In the AF group, the RR for the incidence of serious adverse events in the midazolam versus morphine arm was 0.42 (95% CI, 0.14-1.3). In the group without AF, the RR was 0.46 (95% CI, 0.21-1). The presence of AF did not modify the reduced risk of serious adverse events in the midazolam arm compared with morphine ( P for interaction = 0.88). CONCLUSION: This post hoc analysis of the MIMO trial suggests that the reduced risk of serious adverse events in the midazolam group compared to morphine is similar in patients with and without AF.

Myostatin acts as a negative regulator of muscle growth. Its effect on fat mass is subject to debate. Among alcoholics, there is a high prevalence of muscle atrophy, and increased fat deposition has been also described in these patients. Myostatin could be involved in these alterations, but its relationships with body composition have been scarcely studied in alcoholic patients. To analyze the behavior of myostatin among alcoholics and its relationship with alcohol intake, liver function, and body composition. We investigated serum myostatin in 59 male patients and 18 controls. Patients were all heavy drinkers admitted with organic complications related to excessive ethanol ingestion. Densitometry analysis was used to assess body composition in 46 patients. Handgrip was assessed in 51 patients. Patients showed lower myostatin values than controls (Z = 3.80; p < 0.001). There was a significant relationship between myostatin and fat at the right leg (ρ = 0.32; p = 0.028), left leg (ρ = 0.32; p = 0.028), trunk (ρ = 0.31, p = 0.038), total fat proport ion (ρ = 0.33, p = 0.026), and gynecoid fat distribution (ρ = 0.40, p = 0.006) but not with lean mass (total lean ρ = 0.07; p = 0.63; trunk lean ρ = 0.03; p = 0.85; lower limbs ρ = 0.08; p = 0.58; upper limbs ρ = 0.04 p = 0.82; android ρ = 0.02; p = 0.88, or gynoid lean mass ρ = 0.20; p = 0.19). In total, 80.43% of patients showed at least one criterion of osteosarcopenic adiposity (OSA). Myostatin was related to OSA obesity. We also observed higher myostatin values among patients with body mass index > 30 kg/m2. Serum myostatin was lower among excessive drinkers, and it was related to increased fat deposition among these patients but not to lean mass, handgrip, or bone mineral density.

Objetivo. El ensayo clínico MIMO demostró que los pacientes con edema agudo de pulmón (EAP) tratados con midazolam tenían menos eventos adversos graves (EAG) que los tratados con morfina. Muchos pacientes con EAP tienen fracción de eyección del ventrículo izquierdo (FEVI) preservada ($ 50%). El objetivo fue conocer si la disfunción sistólica ventricular izquierda (DSVI) (fracción eyección ventrículo izquierdo < 50%) modifica el efecto protector del midazolam frente a la morfina.Método. El estudio MIMO asignó al azar 111 pacientes con EAP a tratamiento con midazolam (dosis de 1 mg intravenosa, hasta una dosis máxima de 3 mg, n = 55) o morfina (dosis de 2-4 mg, hasta una dosis máxima de 8 mg, n = 56). Se calculó el riesgo relativo (RR) de padecer un EAG en pacientes con y sin DSVI.Resultado. La FEVI preservada estuvo presente en 84 (75,7%) pacientes con EAP. En el grupo con DSVI, 4 pacientes (26,9%) en el brazo midazolam frente a 6 (50%) en el brazo morfina presentaron EAG (RR = 0,53; IC 95: 0,2-1,4). En el grupo sin DSVI 6 pacientes (15%) del brazo midazolam frente a 18 (40,9%) del brazo morfina presentaron EAG (RR = 0,37; IC 95: 0,16-0,83). La DSVI no modificó el efecto protector del midazolam en la aparición de EAG con respecto a la morfina (p = 0,57)Conclusiones. En pacientes con EAP el efecto protector del midazolam sobre la morfina en la aparición de EAG y EAG o muerte fue similar en pacientes con y sin DSVI. (AU)
Background and objective. The midazolam vs morphine (MIMO) trial showed that patients treated with midazolam had fewer serious adverse events than those treated with morphine. In many patients with acute pulmonary edema, the left ventricular ejection fraction (LVEF) is preserved, at 50% or higher. We aimed to determine whether left ventricular (LV) systolic dysfunction (D), defined by an LVEF of less than 50%, modifies the protective effect of midazolam vs morphine. Methods. The MIMO trial randomized 111 patients with acute pulmonary edema to receive intravenous midazolam in 1-mg doses to a maximum of 3 mg (n = 55) or morphine in 2- to 4-mg doses to a maximum of 8 mg (n= 56). We calculated the relative risk (RR) for a serious adverse event in patients with and without systolic LVD. Results. LVEF was preserved in 84 (75.7%) of the patients with acute pulmonary edema. In patients with systolic LVD, 4 patients (26.9%) in the midazolam arm vs 6 (50%) in the morphine arm developed serious adverse events (RR, 0.53; 95% CI, 0.2-1.4). In patients without systolic LVD, 6 patients (15%) in the midazolam arm vs 18 (40.9%) in the morphine arm experienced such events (RR, 0.37; 95% CI, 0.16-0.83). The presence of systolic LVD did not modify the protective effect of midazolam on serious adverse effects (P=.57). Conclusions. The effect of midazolam vs morphine in protecting against the development of serious adverse eventsor death is similar in patients with and without systolic LVD. (AU)

OBJECTIVE: The s100b inflammatory protein is involved in schizophrenia pathophysiology. We aim at studying the evolution of the s100b serum levels in acutely relapsed paranoid schizophrenia patients at three different time points (admission, discharge and 3 months after hospital discharge 3MAHD). METHODS: Twenty-three paranoid schizophrenia inpatients meeting DSM-IV criteria participated in the research. Twenty-three healthy subjects matched by age, gender and season acted as the control group. Psychopathology was measured with the Positive and Negative Syndrome Scale (PANSS). Serum s100b levels were determined at 12:00 and 24:00 h with an enzyme-linked immunoassay kit. RESULTS: Patients had significant higher serum s100b levels at admission and discharge (12:00 h) than the group of healthy subjects. At admission and discharge, s100b serum levels at 24 h had decreased compared to the 24:00 h s100b levels of the healthy subjects. At 3MAHD patients and healthy subjects had similar levels of serum s100b protein. Positive and negative PANSS scores decreased significantly between admission and discharge. Positive and negative PANSS scores decreased between discharge and 3MAHD, but these changes had no statistical significance. CONCLUSIONS: Our study confirms that the acute inflammatory response produced in acutely relapsed patients is reversed after 3 month of hospital discharge. The variations of serum s100b concentrations when the patients suffer from an acute relapse may be a useful predictor of disease evolution.
