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 ...

This is an executive summary made by a group of experts named Latin American Academy for the study of Lipids (ALALIP). In the current clinical guidelines, atherogenic dyslipidemia (AD) is a poorly recognized entity. Due to the frequent lipid alterations associated with AD in Latin America (LA), we organized a group of experts named (ALALIP) to generate a document in order to analyze their prevalence and to offer practical recommendations. Methodology: using the Delphi methodology, we conducted a comprehensive ...

In 2012, the Colombian Government reduced employer payroll contributions from 29.5 to 16.0 percent. Two years later, the informality rate had diminished by about 4.0 percentage points. This paper attempts to estimate how much of this reduction was due to the tax reform, isolating the impact of other macroeconomic variables. A natural approach to performing this task is to apply a difference-in-differences methodology using a household survey panel. Since the Colombian survey does not have a panel ...

Estimation of conventional Taylor rules for Brazil, Chile, Colombia and Peru shows that central banks increase their repo rate in response to increases in the output gap and, except in Peru, to deviations of inflation expectations from target. Using a Markov-Switching methodology, it is found that, in the presence of external shocks, Chile, Colombia and Peru temporarily abandoned their conventional reaction function. The Taylor Rule is expanded and variables are included related to exchange rate ...

El grado de profundización financiera en Colombia, medido por la relación entre el crédito al sector privado y el PIB, se ubicaba a finales de 2003 por debajo de los niveles que tenía treinta años atrás. Esos niveles son extremadamente bajos en comparación con los de economías desarrolladas y con los de economías en desarrollo exitosas. Este trabajo analiza los vínculos entre dicho indicador de profundización, los flujos externos de capital y la regulación financiera en Colombia, entre 1974 y 2003. ...

Low bone mineral density (BMD) in HIV-infected individuals has been documented in an increasing number of studies. However, it is not clear whether it is the infection itself or the treatment that causes bone impairment. Microindentation measures bone material strength (Bone Material Strength index) directly. We recruited 85 patients, 50 infected with HIV and 35 controls. Median Bone Material Strength index was 84.5 (interquartile range 83-87) in HIV-infected patients and 90 (88.5-93) in controls (P < ...

Reconstruction of bile ducts damaged remains a vexing medical problem. Surgeons have few options when it comes to a long segment reconstruction of the bile duct. Biological scaffolds of decellularized biliary origin may offer an approach to support the replace of bile ducts. Our objective was to obtain an extracellular matrix scaffold derived from porcine extrahepatic bile ducts (dECM-BD) and to analyze its biological and biochemical properties. The efficiency of the tailored perfusion decellularization ...

Large oil accumulation discoveries in the last decade in the pre-salt rock succession off the Brazilian coast aroused renewed interest in carbonate reservoirs, prompting several studies aiming at unravelling the conditions of formation of these rocks. Despite that, there are still many gaps in the knowledge concerning environmental conditions of the deposition of the pre-salt carbonates of Santos Basin, located at the southeastern Brazilian margin. In this study, we present and discuss a new suite ...

Consumers dislike sharing data with fintechs but better access to data can improve loan market outcomes. We study how the California Consumer Privacy Act (CCPA), which grants users control over and mitigates concerns about sharing data, affects bank and fintech lending. Difference-in-differences estimations show that the CCPA increases mortgage applications to fintechs relative to banks in California. Further evidence suggests that applicants' greater willingness to share data improves fintechs' ...

Hepatitis A virus (HAV) is a significant waterborne human pathogen. Of the global supply of potable water, Brazil retains 13%, of which 75% resides in the Amazon Basin. Although hepatitis A morbidity has declined progressively in Brazil as a whole, it remains high in the Amazon region. We used nested and real-time reverse-transcription polymerase chain reaction (RT–PCR) to detect and quantify the viral load in water samples from the Amazon Basin.

In the past two decades, a large body of evidence has established a causative role for the beta-amyloid peptide (Abeta) in Alzheimer's disease (AD). However, recent debate has focused on whether amyloid fibrils or soluble oligomers of Abeta are the main neurotoxic species that contribute to neurodegeneration and dementia. Considerable early evidence has indicated that amyloid fibrils are toxic, but some recent studies support the notion that Abeta oligomers are the primary neurotoxins. While this ...
