Aims: DEPPAS ("Dispositivo Electrónico Personal y Portable en Salud" or Personal, Portable Electronic Health Device in English) is a portable device in form of a bracelet that allows storing electronic health records of older adults experiencing chronic illnesses. The device seeks to support the vital sustainability of older adults by storing critical health information when electronic or paper records have been lost as a consequence of a disaster. Older adults are particularly vulnerable to experience negative consequences in this context.

A bump: what to do next? Ultrasound imaging of superficial soft-tissue palpable lesions.

J Ultrasound

September 2020

Department of Dermatology, Institute for Diagnostic Imaging and Research of the Skin and Soft Tissues Clinic, University of Chile and Pontifical Catholic University of Chile, Santiago, Chile.

Soft-tissue palpable lesions are common in clinical practice, and ultrasound (US) represents the first imaging option in the evaluation of a patient with a soft-tissue swelling. A full and systematic US assessment is necessary, however. This includes grayscale, color- and power-Doppler, spectral-Doppler, and possibly elastography facilities, as well as a trained operator.

Awareness of mental events as mere representations rather than as accurate depictions of reality, also known as dereification, is one of the key features of mindfulness meditation. Dereification is juxtaposed to subjective realism, the process of being lost or totally immersed in the contents of one's mind. Excessive subjective realism is a hallmark of several psychiatric disorders.

Context: Despite a growing interest in service-user involvement in mental health services, the interaction between health institutions and local groups is only beginning to receive attention, particularly in global south settings.

Objective: Looking at a participatory initiative in Chile, this study explores how, under unfavourable administrative conditions, health organizations approach and work with communities.

Methods: We interviewed policy-makers (5), local professionals (10), service users and community representatives (6) linked to a concrete participatory initiative.

Background Pharmacists-led medication reviews (MRs) are claimed to be effective for the control of cardiovascular diseases; however, the evidence in the literature is conflicting. The main objective of this meta-analysis was to analyze the impact of pharmacist-led MRs on cardiovascular disease risk factors overall and in different ambulatory settings while exploring the effects of different components of MRs. Methods and Results Searches were conducted in PubMed, Web of Science, Embase, the Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library Central Register of Controlled Trials database.

Precession modulation of the South Pacific westerly wind belt over the past million years.

Proc Natl Acad Sci U S A

November 2019

Royal Netherlands Institute for Sea Research (NIOZ), Ocean Systems (TX), Utrecht University, 1790 AB, Den Burg, Texel, The Netherlands.

The southern westerly wind belt (SWW) interacts with the Antarctic Circumpolar Current and strongly impacts the Southern Ocean carbon budget, and Antarctic ice-sheet dynamics across glacial-interglacial cycles. We investigated precipitation-driven sediment input changes to the Southeast Pacific off the southern margin of the Atacama Desert over the past one million years, revealing strong precession (19/23-ka) cycles. Our simulations with 2 ocean-atmosphere general circulation models suggest that observed cyclic rainfall changes are linked to meridional shifts in water vapor transport from the tropical Pacific toward the southern Atacama Desert.

Background: Odanacatib, a cathepsin K inhibitor, reduces bone resorption while maintaining bone formation. Previous work has shown that odanacatib increases bone mineral density in postmenopausal women with low bone mass. We aimed to investigate the efficacy and safety of odanacatib to reduce fracture risk in postmenopausal women with osteoporosis.

Article Synopsis
  • The study aimed to create and validate the first evidence-based guidelines for minimally invasive pancreas resection (MIPR) ahead of a key meeting in Miami in 2019.
  • Despite promising results from early adopters, there were no existing guidelines for clinical practice in this rapidly developing field.
  • Using rigorous methodologies, the study reviewed 16,069 titles and included 291 studies to develop 28 recommendations covering various aspects of MIPR, from techniques to patient safety and training.

We present a case of locally advanced pancreatic cancer with duodenal invasion treated with consolidative chemoradiation, where extensive unpredictable interfraction motion was observed. Initially, two attempts were made to treat with volumetric modulated arc therapy technique. However, due to substantial interfractional motion of the pancreatic head mass relative to the regional nodal areas, the patient was eventually replanned and treated with a four-field box technique.

Background: Primary resuscitation fluid to treat hemorrhagic shock remains controversial. Use of hydroxyethyl starches raised concerns of acute kidney injury. Polyethylene-glycolated carboxyhemoglobin, which has carbon monoxide-releasing molecules and oxygen-carrying properties, was hypothesized to sustain cortical renal microcirculatory PO2 after hemorrhagic shock and reduce kidney injury.

Elite athletes are subject to injuries like the Achilles tendon rupture. This injury requires a long recovery process, with no guarantee of returning to the pre-injury level. When a rupture happens during natural life, movement analysis can provide useful insights concerning patterns of rupture to understand and prevent Achilles tendon injuries.

Background: On Dec 1, 2006, Mexico's public health-care insurance scheme, Seguro Popular, implemented the Medical Insurance Century XXI (SMSXXI) programme, to provide insurance to children younger than 5 years without social security. SMSXXI aims to increase access to health services, decrease out-of-pocket health expenses (OOPHE), and reduce health inequities. SMSXXI covers uninsured, primarily low-income, populations who might be most at risk of the financial and health consequences of costly medical interventions.

Relationships with primary caregivers provide the context for early childhood development, and evaluating those relationships during the early years can detect difficulties that may influence future mental health. Video feedback is a valuable intervention tool in early childhood, both for family relationships and child development. An intervention was implemented using this technique, focused on mother-father-child triads that were experiencing difficulties in social-emotional development.

The Response of CH34 to Cadmium Involves Inhibition of the Initiation of Biofilm Formation, Decrease in Intracellular c-di-GMP Levels, and a Novel Metal Regulated Phosphodiesterase.

Front Microbiol

July 2019

Laboratorio de Microbiología Molecular y Biotecnología Ambiental, Departamento de Química and Centro de Biotecnología, Universidad Técnica Federico Santa María, Valparaíso, Chile.

Cadmium is a highly toxic heavy metal for biological systems. CH34 is a model strain to study heavy metal resistance and bioremediation as it is able to deal with high heavy metal concentrations. Biofilm formation by bacteria is mediated by the second messenger -(3'-5')-cyclic dimeric guanosine monophosphate (c-di-GMP).

Mitochondria-associated membranes (MAMs) are central microdomains that fine-tune bioenergetics by the local transfer of calcium from the endoplasmic reticulum to the mitochondrial matrix. Here, we report an unexpected function of the endoplasmic reticulum stress transducer IRE1α as a structural determinant of MAMs that controls mitochondrial calcium uptake. IRE1α deficiency resulted in marked alterations in mitochondrial physiology and energy metabolism under resting conditions.
