Prevalence and impact on prognosis of right-bundle branch block in patients with acute heart failure: Findings from the RICA registry.

Objectives: This work aims to determine the prevalence, characteristics, and impact on prognosis of right bundle branch block (RBBB) in a cohort of acute heart failure (AHF) patients.

Methods: We prospectively analyzed 3,638 AHF patients included in the RICA registry (National Heart Failure Registry of the Spanish Internal Medicine Society). We independently analyzed the relationship between baseline and clinical characteristics and the presence of RBBB as well as the potential impact of RBBB on 1-year all-cause mortality and a composite endpoint of 90-day post-discharge hospitalization or death.

Preoperative fasting for the infusion of "yerba mate": a randomized clinical trial with ultrasound evaluation of gastric contents.

Background: The traditional infusion of "yerba mate" is widely consumed in South America and exported to countries around the world. Although generally considered a "clear fluid", there is no data to date on the gastric emptying time of yerba mate and safe preoperative fasting intervals. The objective of this study was to evaluate the gastric emptying time of a standardized infusion of yerba mate using bedside ultrasound and compare it with the time confirm of hot and cold tea.

Frontotemporal Dementias in Latin America: History, Epidemiology, Genetics, and Clinical Research.

The historical development, frequency, and impact of frontotemporal dementia (FTD) are less clear in Latin America than in high-income countries. Although there is a growing number of dementia studies in Latin America, little is known collectively about FTD prevalence studies by country, clinical heterogeneity, risk factors, and genetics in Latin American countries. A systematic review was completed, aimed at identifying the frequency, clinical heterogeneity, and genetics studies of FTD in Latin American populations.

Tobacco Use and the Kidney: A Review of Public Policies and Studies on Kidney Disease Progression.

Clinical Background: Cigarette smoking is one of the leading causes of preventable deaths, including cardiovascular diseases and cancer. However, the effects of tobacco use on chronic kidney disease (CKD) are less widespread. Epidemiology: Smoking tobacco is associated with proteinuria and attenuation of glomerular filtration rate in the general population of different ethnicities.

Endovascular treatment of coronary subclavian steal syndrome: a case series highlighting the diagnostic usefulness of a multimodality imaging approach.

Background: Coronary subclavian steal syndrome (CSSS) is an uncommon complication observed in patients after coronary artery bypass surgery with left internal mammary artery (LIMA) grafts. It is defined as coronary ischaemia due to reversal flow from the LIMA to the left subclavian artery (SA) when a proximal left SA stenosis is present. In practice, the entire clinical spectrum of ischaemic heart disease, ranging from asymptomatic patients to acute myocardial infarction, may be encountered.

Incidental Findings Suggestive of COVID-19 Pneumonia in Oncologic Patients Undergoing F-FDG PET/CT Studies: Association Between Metabolic and Structural Lung Changes.

Although the novel coronavirus disease 2019 (COVID-19) can present as nonspecific clinical forms, subclinical cases represent an important route of transmission and a significant source of mortality, mainly in high-risk subpopulations such as cancer patients. A deeper knowledge of the metabolic shift in cells infected with severe acute respiratory syndrome coronavirus 2 could provide new insights about its pathogenic and host response and help to diagnose pulmonary involvement. We explored the potential added diagnostic value of F-FDG PET/CT scans in asymptomatic cancer patients with suspected COVID-19 pneumonia by investigating the association between metabolic and structural changes in the lung parenchyma.

Spinal cord compression due to a solitary, bulky plasmacytoma of posterior mediastinum.

Solitary plasmacytoma is a rare clonal plasma cell tumor, representing 2-5% of plasma cell disorders. The standard treatment is local radiotherapy. However, in some cases, its use is limited by the size and/or location of the mass.

Creation of a pioneering interdisciplinary genital dermatology unit for Hispanic men: First 269 patients.

The role of circumcision in partially protecting against sexually transmitted infections (STIs) and other dermatoses has been documented. Neonatal circumcision is not routinely practiced in South America. Although it is logical to assume that male genital dermatoses are more prevalent in Hispanic men, they are underrepresented in the existing literature.

2021 Update of the International Council for Standardization in Haematology Recommendations for Laboratory Measurement of Direct Oral Anticoagulants.

In 2018, the International Council for Standardization in Haematology (ICSH) published a consensus document providing guidance for laboratories on measuring direct oral anticoagulants (DOACs). Since that publication, several significant changes related to DOACs have occurred, including the approval of a new DOAC by the Food and Drug Administration, betrixaban, and a specific DOAC reversal agent intended for use when the reversal of anticoagulation with apixaban or rivaroxaban is needed due to life-threatening or uncontrolled bleeding, andexanet alfa. In addition, this ICSH Working Party recognized areas where additional information was warranted, including patient population considerations and updates in point-of-care testing.

[Pellagra: an ancient disease in a modern world].

Introduction: pellagra is a systemic disease due to deficiency of vitamin B3 or tryptophan, its precursor. Vitamin B3 is needed for several metabolic processes, cell signaling, and DNA repair. It is characterized by a classic tetrad of dermatitis, diarrhea, dementia, and death.

Treatment of relapsed and refractory multiple myeloma: recommendations from the International Myeloma Working Group.

This Policy Review presents the International Myeloma Working Group's clinical practice recommendations for the treatment of relapsed and refractory multiple myeloma. Based on the results of phase 2 and phase 3 trials, these recommendations are proposed for the treatment of patients with relapsed and refractory disease who have received one previous line of therapy, and for patients with relapsed and refractory multiple myeloma who have received two or more previous lines of therapy. These recommendations integrate the issue of drug access in both low-income and middle-income countries and in high-income countries to help guide real-world practice and thus improve patient outcomes.

The aim of this survey-based study was to provide a general overview of plastic surgery training in this region.

Clinical relevance of incidental focal breast uptake on fluorine-18 fluorodeoxyglucose PET/computed tomography studies: an experience in a high-load center of Spain.

Aim: We aimed to determine the frequency and clinical significance of breast incidental uptake (BIU) detected through fluorine-18 fluorodeoxyglucose (18F-FDG) PET/computed tomography (CT) in a single, high-load center.

Patients And Methods: In this retrospective study, we analyzed a total of 13 763 PET/CT studies performed from January 2017 to January 2020. After excluding 3148 scans, the maximum standardized uptake value (SUVmax) and maximum diameter (cm) of each BIU were measured.

Causes of death in hospitalized patients in internal medicine departments with heart failure according to ejection fraction. RICA registry.

Introduction: There are few data in the Spanish population about the causes of death in patients admitted to internal medicine departments for heart failure. Their study according to left ventricular ejection fraction (reduced: rEF, mid-range: mEF, and preserved: pEF) could improve the knowledge of patients and their prognosis.

Methods: Prospective multicentre cohort study of 4144 patients admitted with heart failure to internal medicine departments.

Assessment of extra-parenchymal lung involvement in asymptomatic cancer patients with COVID-19 pneumonia detected on F-FDG PET-CT studies.

Background: Lung involvement in patients with coronavirus disease 2019 (COVID-19) undergoing PET-CT has been previously reported. However, FDG uptake outside lung parenchyma was poorly characterized in detail. We evaluated the extra-parenchymal lung involvement in asymptomatic cancer patients with COVID-19 pneumonia through F-FDG PET-CT.

Epidemiology of heart failure with preserved ejection fraction: Results from the RICA Registry.

Introduction And Objectives: There is great interest in better characterizing patients with heart failure (HF) with preserved ejection fraction (HF-PEF). The objective of this study is to determine the prevalence, progression over time and to describe the clinical and epidemiological characteristics of patients with HF-PEF.

Methods: From the National Registry of Heart Failure (RICA, prospective multicentre cohort study) we analysed patients consecutively admitted for HF in Internal Medicine wards over a period of 11 years (2008-2018).

Incidental and simultaneous finding of pulmonary thrombus and COVID-19 pneumonia in a cancer patient derived to F-FDG PET/CT. New pathophysiological insights from hybrid imaging.

Cancer patients require a careful clinical follow-up during the coronavirus disease 2019 (COVID-19) pandemic. Although hybrid fluorine-18 Fluorodeoxyglucose (F-FDG) positron emission tomography-computed tomography (PET/CT) is not routinely used in the management of COVID-19 patients, it could play a complementary role of other laboratory and radiological data in selected cases. We describe an asymptomatic cancer patient derived to F-FDGPET/CT with simultaneous findings of COVID-19 pneumonia and pulmonary thrombus, discussing its possible mechanisms and prognostic implications.

Multisystemic fusariosis with fulminant evolution.

This report presents the case of a 13-year-old female patient with history of acute myeloid leukemia, who, after a bone marrow transplant, began to vomit and experienced rapidly progressive deterioration of consciousness, in addition to disseminated erythematous-violaceous macules, and some blisters with hemorrhagic content inside.

Ambulatory blood pressure monitoring over 24 h: A Latin American Society of Hypertension position paper-accessibility, clinical use and cost effectiveness of ABPM in Latin America in year 2020.

Accurate office blood pressure measurement remains crucial in the diagnosis and management of hypertension worldwide, including Latin America (LA). Office blood pressure (OBP) measurement is still the leading technique in LA for screening and diagnosis of hypertension, monitoring of treatment, and long-term follow-up. Despite this, due to the increasing awareness of the limitations affecting OBP and to the accumulating evidence on the importance of ambulatory BP monitoring (ABPM), as a complement of OBP in the clinical approach to the hypertensive patient, a progressively greater attention has been paid worldwide to the information on daytime and nighttime BP patterns offered by 24-h ABPM in the diagnostic, prognostic, and therapeutic management of hypertension.

Recommendations for home blood pressure monitoring in Latin American countries: A Latin American Society of Hypertension position paper.

Out-of-office blood pressure (BP) monitoring appears to be a very useful approach to hypertension management insofar it allows to obtain multiple measurements in the usual environment of each individual, allows the detection of hypertension phenotypes, such as white-coat and masked hypertension, and appears to have superior prognostic value than the conventional office BP measurements. Out-of-office BP can be obtained through either home or ambulatory monitoring, which provide complementary and not identical information. Home BP monitoring yields BP values self-measured in subjects' usual living environment; it is an essential method for the evaluation of almost all untreated and treated subjects with suspected or diagnosed hypertension, best if combined with telemonitoring facilities, also allowing long-term monitoring.
