Fossil group origins - VI. Global X-ray scaling relations of fossil galaxy clusters
We present the first pointed X-ray observations of 10 candidate fossil galaxy
groups and clusters. With these Suzaku observations, we determine global
temperatures and bolometric X-ray luminosities of the intracluster medium (ICM)
out to for six systems in our sample. The remaining four systems show
signs of significant contamination from non-ICM sources. For the six objects
with successfully determined properties, we measure global
temperatures in the range ,
bolometric X-ray luminosities of , and estimate masses,
as derived from , of .
Fossil cluster scaling relations are constructed for a sample that combines our
Suzaku observed fossils with fossils in the literature. Using measurements of
global X-ray luminosity, temperature, optical luminosity, and velocity
dispersion, scaling relations for the fossil sample are then compared with a
control sample of non-fossil systems. We find the fits of our fossil cluster
scaling relations are consistent with the relations for normal groups and
clusters, indicating fossil clusters have global ICM X-ray properties similar
to those of comparable mass non-fossil systems.Comment: 17 pages, 7 figures, 8 tables. Accepted for publication in MNRA
Una disfagia con chispa
An 81-year-old woman is admitted to Neurosurgery with a severe subarachnoid haemorrhage. She develops mixed dysphagia related to neurological sequelae and the presence of a tracheostomy.
An endoscopic study is performed for the placement of a gastrostomy feeding tube showing oesophageal food impactation of a dense material occupying at least half the length of the oesophagus. Poor lung performance made unfeasible the extraction of this material.
Removal of the tracheostomy recovered swallowing in our patient and we started her on oral Coca-Cola™ 330 ml daily. A new endoscopic study performed after 4 days showed a normal mucosa of the oesophagus and stomach and de disappearance of the impacted bolus. The patient was discharged eating a normal diet 6 days later.Mujer de 81 años, hipertensa, que ingresa en Neurocirugía por una hemorragia subaracnoidea grave. Desarrolla disfagia en relación con sus secuelas neurológicas y la presencia de una traqueostomía.
La endoscopia alta, realizada para la colocación de una sonda de gastrostomía para alimentación enteral, muestra la presencia de un bolo impactado extenso en el esófago que impide al paso del endoscopio al estómago. No se puede extraer por desaturación de la paciente.
La retirada de la traqueostomía logra recuperar la deglución. La paciente recibe 30 ml diarios de Coca-Cola™ por vía oral y, al cuarto día, una nueva endoscopia muestra normalidad de la mucosa esofágica y gástrica y desaparición del bolo impactado
Cancer Impacts Prognosis on Mortality in Patients with Acute Heart Failure: Analysis of the EPICTER Study
Introduction: Heart failure (HF) and cancer are currently the leading causes of death
worldwide, with an increasing incidence with age. Little is known about the treatment received and
the prognosis of patients with acute HF and a prior cancer diagnosis. Objective: to determine the
clinical characteristics, palliative treatment received, and prognostic impact of patients with acute HF
and a history of solid tumor. Methods: The EPICTER study (“Epidemiological survey of advanced
heart failure”) is a cross-sectional, multicenter project that consecutively collected patients admitted
for acute HF in 74 Spanish hospitals. Patients were classified into two groups according to whether
they met criteria for acute HF with and without solid cancer, and the groups were subsequently
compared. A multivariable logistic regression analysis was conducted, using the forward stepwise
method. A Kaplan–Meier survival analysis was performed to evaluate the impact of solid tumor
on prognosis in patients with acute HF. Results: A total of 3127 patients were included, of which
394 patients (13%) had a prior diagnosis of some type of solid cancer. Patients with a history of cancer
presented a greater frequency of weight loss at admission: 18% vs. 12% (p = 0.030). In the cancer
group, functional impairment was noted more frequently: 43% vs. 35%, p = 0.039). Patients with a
history of solid cancer more frequently presented with acute HF with preserved ejection fractiono
(65% vs. 58%, p = 0.048) than reduced or mildly reduced. In-hospital and 6-month follow-up mortality
was 31% (110/357) in patients with solid cancer vs. 26% (637/2466), p = 0.046. Conclusion: Our investigation demonstrates that in-hospital mortality and mortality during 6-month follow-up in
patients with acute HF were higher in those subjects with a history of concomitant solid tumor cancer

Usefulness of Serial Multiorgan Point-of-Care Ultrasound in Acute Heart Failure: Results from a Prospective Observational Cohort.
Background and Objectives: Acute heart failure (AHF) is a common disease and a cause
of high morbidity and mortality, constituting a major health problem. The main purpose of this
study was to determine the impact of multiorgan ultrasound in identifying pulmonary hypertension
(PH), a major prognostic factor in patients admitted due to AHF, and assess whether there are
significant changes in the venous excess ultrasonography (VE US) score or femoral vein Doppler at
discharge. Materials and Methods: Patients were evaluated with a standard protocol of lung ultrasound,
echocardiography, inferior vena cava (IVC) and hepatic, portal, intra-renal and femoral vein Doppler
flow patterns at admission and on the day of discharge. Results: Thirty patients were enrolled during
November 2021. The mean age was seventy-nine years (Standard Deviation–SD 13.4). Seven patients
(23.3%) had a worsening renal function during hospitalization. Regarding ultrasound findings,
VE US score was calculated at admission and at discharge, unexpectedly remaining unchanged or
even worsened (21 patients, 70.0%). The area under the curve for the lung score was 83.9% (p = 0.008),
obtaining a cutoff value of 10 that showed a sensitivity of 82.6% and a specificity of 71.4% in the
identification of intermediate and high PH. It was possible to monitor significant changes between
both exams on the lung score (16.5 vs. 9.3; p < 0.001), improvement in the hepatic vein Doppler
pattern (2.4 vs. 2.1; p = 0.002), improvement in portal vein Doppler pattern (1.7 vs. 1.4; p = 0.023),
without significant changes in the intra-renal vein Doppler pattern (1.70 vs. 1.57; p = 0.293), VE US
score (1.3 vs. 1.1; p = 0.501), femoral vein Doppler pattern (2.4 vs. 2.1; p = 0.161) and IVC collapsibility
(2.0 vs. 2.1; p = 0.420). Conclusions: Our study results suggest that performing serial multiorgan
Point-of-Care ultrasound can help us to better identify high and intermediate probability of PH
patients with AHF. Currently proposed multi-organ, venous Doppler scanning protocols, such as the
VE US score, should be further studied before expanding its use in AHF patients.post-print2977 K
Interleukin-6 Could Be a Potential Prognostic Factor in Ambulatory Elderly Patients with Stable Heart Failure: Results from a Pilot Study
Introduction: Inflammation is a fundamental phenomenon in heart failure, but the prognostic or therapeutic role of markers such as interleukin-6 (IL-6) has not yet been clarified. The objective of this study is to describe the clinical profile of patients with elevated IL-6 and determine if they have worse clinical outcomes. Methods: A retrospective c.ohort observational study including 78 patients with heart failure followed up at the Heart Failure Outpatient Clinic of the Internal Medicine Department. IL-6 was determined in all patients, who were then assigned into two groups according to IL-6 level (normal or high). Clinical and prognostic data were collected to determine the differences in both groups. Results: The average age was 79 years, 60% female. A total of 53.8% of the patients had elevated IL-6 (group 2). Patients with elevated IL-6 presented more frequently with anemia mellitus (64.3% vs. 41.7%; p = 0.046), atrial fibrillation (83.3% vs. 61.9% p = 0.036), dyslipidemia (76.2% vs. 58.2%; p = 0.03), higher creatinine levels (1.35 mg/dL vs. 1.08 mg/dL; p = 0.024), lower glomerular filtration rate (43.6 mL/min/m2 vs. 59.9 mL/min/m2; p = 0.007), and anemia 25% vs. 52.4% p = 0.014. The factors independently associated with the increase in IL-6 were anemia 3.513 (1.163–10.607) and renal failure 0.963 (0.936–0.991), p < 0.05. Mortality was higher in the group with elevated IL-6 levels (16% vs. 2%; p = 0.044) with a log-rank p = 0.027 in the Kaplan–Meier curve. Conclusion: Patients with heart failure and elevated IL-6 most often have atrial fibrillation, diabetes mellitus, dyslipidemia, anemia, and renal failure. In addition, mortality was higher and a tendency of higher hospital admission was observed in stable HF patients with elevated IL-6
Trends and Clinical Impact of Gastrointestinal Endoscopic Procedures on Acute Heart Failure in Spain (2002–2017)
Introduction: Heart failure decompensation can be triggered by many factors, including anemia. In cases of iron deficiency anemia or iron deficiency without anemia, endoscopic studies are recommended to rule out the presence of gastrointestinal neoplasms or other associated bleeding lesions. Objectives: The aims of this study were to (i) examine trends in the incidence, clinical characteristics, and in-hospital outcomes of patients hospitalized with heart failure from 2002 to 2017 who underwent esophagogastroduodenoscopy (EGD) and/or colonoscopy, and to (ii) identify factors associated with in-hospital mortality (IHM) among patients with heart failure who underwent an EGD and/or a colonoscopy. Methods: We conducted an observational retrospective epidemiological study using the Spanish National Hospital Discharge Database (SNHDD) between 2002 and 2017. We included hospitalizations of patients with a primary discharge diagnosis of heart failure. Cases were reviewed if there was an ICD-9-CM or ICD-10 procedure code for EGD or colonoscopy in any procedure field. Multivariable logistic regression models were constructed to identify predictors of IHM among HF patients who underwent an EGD or colonoscopy. Results: A total of 51,187 (1.32%) non-surgical patients hospitalized with heart failure underwent an EGD and another 72,076 (1.85%) patients had a colonoscopy during their admission. IHM was significantly higher in those who underwent an EGD than in those who underwent a red blood cell transfusion (OR 1.10; 95%CI 1.04–1.12). However, the use of colonoscopy seems to decrease the probability of IHM (OR 0.45; 95%CI 0.41–0.49). In patients who underwent a colonoscopy, older age seems to increase the probability of IHM. However, EGD was associated with a lower mortality (OR 0.60; 95% CI 0.55–0.64). Conclusion: In our study, a decrease in the number of gastroscopies was observed in relation to colonoscopy in patients with heart failure. The significant ageing of the hospitalized HF population seen over the course of the study could have contributed to this. Both procedures seemed to be associated with lower in-hospital mortality, but in the case of colonoscopy, the risk of in-hospital mortality was higher in elderly patients with heart failure and associated neoplasms. Colonoscopy and EGD seemed not to increase IHM in patients with heart failure
Sex Differences in the Incidence and Outcomes of Acute Myocardial Infarction in Spain, 2016–2018: A Matched-Pair Analysis
(1) Background: Our aim was to analyze the incidence, procedures, and in-hospital outcomes of myocardial infarction (MI) in Spain (2016–2018) according to sex.
(2) Methods: We estimated the incidence of an ST elevation myocardial infarction (STEMI) and non-ST elevation myocardial infarction (NSTEMI) according to sex using the Spanish National Hospital Discharge Database. A matched-pair analysis was used.
(3) Results: MI was coded in 156,826 patients aged ≥18 years (111,842 men and 44,984 women). Men showed higher incidence rates (205.0 vs. 77.8 per 100,000; p < 0.001; IRR = 2.81(95%CI:2.78–2.84)). After matching, the use of coronary artery by-pass grafting (CABG) (1.0% vs. 0.7%; p < 0.001) and percutaneous coronary intervention (PCI) (57.8% vs. 52.3%; p < 0.001) was higher among men with an STEMI, whereas the in-hospital mortality (IHM) remained higher among women (11.2% vs. 10.1%; p < 0.001). Likewise, CABG (1.9% vs. 3.3%; p < 0.001) and PCI (33.8% vs. 41.9%; p < 0.001) were less often used among women with an NSTEMI, but no sex-related differences were found in IHM. After adjusting for confounders, IHM was more than twofold higher for both men and women with an STEMI than those with an NSTEMI. Women with an STEMI had a 21% higher mortality risk than men (OR = 1.21(95%CI:1.13–1.29).
(4) Conclusion: Men had higher incidence rates of MI than women. Women underwent invasive procedures less often and had a higher IHM when admitted for an STEMI
Registro fotográfico de tres especies de felinos (Carnivora: Felidae) simpátricos en el Parque Nacional Machalilla, costa del Ecuador
The Machalilla National Park (PNM) located in the Tumbes-Chocó-Magdalena hotspot in western Ecuador, contains high levels of biodiversity and endemism; however, it presents a constant loss and degradation of its habitat due to anthropogenic activity. In this work, the presence of wild cats within the protected area of the PNM was determined. 60 trap cameras were located within the 56,184 ha of the PNM land area, between the months of October 2018 and February 2019. During this period, the presence of three species of wild cats was detected: ocelot (Leopardus pardalis), margay (Leopardus wiedii) and yaguarundí (Herpailurus yagouaroundi). This note presents a particular case in which the presence of the three feline species was reported coinciding in one of the trap chambersEl Parque Nacional Machalilla (PNM) ubicado en el hotspot Tumbes-Chocó-Magdalena al oeste de Ecuador, contiene altos niveles de biodiversidad y endemismo; sin embargo, presenta una constante pérdida y degradación de su hábitat debido a la actividad antrópica.

Incidence and Outcomes of Hemorrhagic Stroke among Adults in Spain (2016–2018) According to Sex: A Retrospective, Cohort, Observational, Propensity Score Matched Study
(1) Background: We aim to analyze sex differences in the incidence, clinical characteristics and in-hospital outcomes of hemorrhagic stroke (HS) in Spain (2016–2018) using the National Hospital Discharge Database.
(2) Methods: Retrospective, cohort, observational study. We estimated the incidence of HS in men and women. We analyzed comorbidity, treatments, procedures, and hospital outcomes. We matched each woman with a man by age, type of HS and medical conditions using propensity score matching.
(3) Results: HS was coded in 57,227 patients aged ≥18 years (44.3% women). Overall, men showed higher incidence rates (57.3/105 vs. 43.0/105; p < 0.001; IRR = 1.60; 95% CI: 1.38–1.83). Women suffered more subarachnoid hemorrhages (25.2% vs. 14.6%), whereas men more often had intracerebral hemorrhages (55.7% vs. 54.1%). In-hospital mortality (IHM) was higher for intracerebral hemorrhage in both men and women. Women underwent decompressive craniectomy less often than men (5.0% vs. 6.2%; p < 0.001). After matching, IHM among women was higher (29.0% vs. 23.7%; p < 0.001). Increments in age, comorbidity and use of anticoagulants and antiplatelet agents prior to hospitalization were associated were higher IHM, and decompressive craniectomy was associated with lower IHM in both sexes. After multivariable adjustment, women had higher IHM (OR = 1.23; 95% CI: 1.18–1.28).
(4) Conclusion: Men had higher incidence rates of HS than women. Women less often underwent decompressive craniectomy. IHM was higher among women admitted for HS than among men
Chronic Obstructive Pulmonary Disease in Elderly Patients with Acute and Advanced Heart Failure: Palliative Care Needs—Analysis of the EPICTER Study
Introduction: There are studies that evaluate the association between chronic obstructive pulmonary disease (COPD) and heart failure (HF) but there is little evidence regarding the prognosis of this comorbidity in older patients admitted for acute HF. In addition, little attention has been given to the extracardiac and extrapulmonary symptoms presented by patients with HF and COPD in more advanced stages. The aim of this study was to evaluate the prognostic impact of COPD on mortality in elderly patients with acute and advanced HF and the clinical manifestations and management from a palliative point of view. Methods: The EPICTER study (Epidemiological survey of advanced heart failure) is a cross-sectional, multicenter project that consecutively collected patients admitted for HF in 74 Spanish hospitals. Demographic, clinical, treatment, organ-dependent terminal criteria (NYHA III-IV, LVEF <20%, intractable angina, HF despite optimal treatment), and general terminal criteria (estimated survival <6 months, patient/family acceptance of palliative approach, and one of the following: evidence of HF progression, multiple Emergency Room visits or admissions in the last six months, 10% weight loss in the last six months, and functional impairment) were collected. Terminal HF was considered if the patient met at least one organ-dependent criterion and all the general criteria. Both groups (HF with COPD and without COPD) were compared. A Kaplan-Meier survival analysis was performed to evaluate the presence of COPD on the vital prognosis of patients with HF. Results: A total of 3100 patients were included of which 812 had COPD. In the COPD group, dyspnea and anxiety were more frequently observed (86.2% vs. 75.3%, p = 0.001 and 35.4% vs. 31.2%, p = 0.043, respectively). In patients with a history of COPD, presentation of HF was in the form of acute pulmonary edema (21% vs. 14.4% in patients without COPD, p = 0.0001). Patients with COPD more frequently suffered from advanced HF (28.9% vs. 19.4%; p < 0.001). Consultation with the hospital palliative care service during admission was more frequent when patients with HF presented with associated COPD (94% vs. 6.8%; p = 0.036). In-hospital and six-month follow-up mortality was 36.5% in patients with COPD vs. 30.7% in patients without COPD, p = 0.005. The mean number of hospital admissions during follow-up was higher in patients with HF and COPD than in those with isolated HF (0.63 +/- 0.98 vs. 0.51 +/- 0.84; p < 0.002). Survival analysis showed that patients with a history of COPD had fewer survival days during follow-up than those without COPD (log Rank chi-squared 4.895 and p = 0.027). Conclusions: patients with HF and COPD had more severe symptoms (dyspnea and anxiety) and also a worse prognosis than patients without COPD. However, the prognosis of patients admitted to our setting is poor and many patients with HF and COPD may not receive the assessment and palliative care support they need. Palliative care is necessary in chronic non-oncologic diseases, especially in multipathologic and symptom-intensive patients. This is a clinical care aspect to be improved and evaluated in future research studies
