BioSin UFMG Club: Engaging a multilevel and multidisciplinary community in synthetic biology.

Learning synthetic biology is often seen as a far distant possibility, restricted to those who have the privilege of an academic career. We propose a student-centered discussion group around synthetic biology, aimed at people from high school onwards with different backgrounds to interact and learn about synthetic biology. We developed a 14-week long program with three modules: "Leveling," "Introducing," and "Discussion.

Antigenicity and adhesiveness of a Plasmodium vivax VIR-E protein from Brazilian isolates.

Background: Plasmodium vivax, the major cause of malaria in Latin America, has a large subtelomeric multigene family called vir. In the P. vivax genome, about 20% of its sequences are vir genes.

The effect of oral contraceptive use on cortisol reactivity to the Trier Social Stress Test: A meta-analysis.

Background: Some research suggests that oral contraceptive pills (OCPs) blunt the cortisol stress response, thus OCP users are often excluded from stress research. The current study examined changes in salivary cortisol among females taking OCPs and naturally cycling (NC) females after exposure to the Trier Social Stress Test (TSST).

Methods: The literature search included the terms "oral contraceptives" OR "oral contraception" OR "birth control" OR "birth control pill" AND "Trier Social Stress Test" OR "TSST" AND "cortisol" OR "salivary cortisol.

Comprehensive meta-analysis of resilience interventions.

Background/rationale: There is no current consensus on operational definitions of resilience. Instead, researchers often debate the optimal approach to understanding resilience, while continuing to explore ways to enhance and/or promote its qualities in various populations. The goal of the current meta-analysis is to substantiate existing evidence examining the promotion of resilience through various interventions.

Plasmodium vivax AMA1: Implications of distinct haplotypes for immune response.

In Brazil, Plasmodium vivax infection accounts for around 80% of malaria cases. This infection has a substantial impact on the productivity of the local population as the course of the disease is usually prolonged and the development of acquired immunity in endemic areas takes several years. The recent emergence of drug-resistant strains has intensified research on alternative control methods such as vaccines.

Technical note: A comparison of methods to determine pH in silages.

The techniques used to assess pH in silages vary greatly. The aim of this study was to evaluate the effects of water-to-sample ratio, extraction procedure, and standing time on pH determination. Silage samples (n = 20 for each silage) were chosen to represent diverse crops (corn, elephant grass, sugarcane, and forage peanut) to have a varied ensilability index and thus a wide range in final pH.

The efficacy of stress reappraisal interventions on stress responsivity: A meta-analysis and systematic review of existing evidence.

Background: The beliefs we hold about stress play an important role in coping with stressors. Various theoretical frameworks of stress point to the efficacy of reframing stress-related information through brief reappraisal interventions in order to promote adaptive coping.

Purpose: The goal of the current meta-analysis and systematic review is to substantiate the efficacy of reappraisal interventions on stress responsivity compared to control conditions.

Background/rationale: The carbon dioxide (CO) challenge has been reliably used in laboratory settings as a panicogen in clinical populations. However, the magnitude of these effects on healthy and non-clinical control populations are not clear. The aim of this meta-analysis and systematic review is to provide quantitative estimates of those effects.

Controversies in the Use of Lipid Injectable Emulsion in Hospitalized Patients.

Soybean oil-based lipid injectable emulsion (SO-based ILE) is an 18-carbon, ω-6 macronutrient providing a concentrated source of calories, which can be administered in or with parenteral nutrition to patients unable to tolerate or consume adequate enteral nutrition. Beyond the provision of energy, SO-based ILE provides linoleic and linolenic acid, 2 essential fatty acids necessary for the prevention of essential fatty acid deficiency. However, SO-based ILE with its high levels of ω-6 fatty acids, long-chain triglycerides, phospholipid emulsifiers, and glycerin has been associated with worsening clinical outcomes, including increase of infections, lengthier intensive care and hospital stay, and prolonged mechanical ventilation.

'Who's Covering This Patient?' Developing a First-Contact Provider (FCP) Designation in an Electronic Health Record.

Background: Safe and efficient inpatient care depends on accurate identification of the licensed independent practitioner (LIP) primarily responsible for each admitted patient. The inability to do so has far-reaching consequences, including poor communication among care teams, delays in patient care (including critical result reporting), and significant threats to patient safety.

Methods: At the University of Chicago Medical Center, an 800-bed academic hospital, a new Epic feature, called First-Contact Provider (FCP), was developed to identify the responsible LIP for each inpatient.

Parenteral nutrition (PN) is a high-alert medication with a complex drug use process. Key steps in the process include the review of each PN prescription followed by the preparation of the formulation. The preparation step includes compounding the PN or activating a standardized commercially available PN product.

Standardized Competencies for Parenteral Nutrition Prescribing: The American Society for Parenteral and Enteral Nutrition Model.

Parenteral nutrition (PN) provision is complex, as it is a high-alert medication and prone to a variety of potential errors. With changes in clinical practice models and recent federal rulings, the number of PN prescribers may be increasing. Safe prescribing of this therapy requires that competency for prescribers from all disciplines be demonstrated using a standardized process.

Total nutrient admixtures (3-in-1): pros vs cons for adults.

Total nutrient admixture (TNA) is a complete parenteral nutrition (PN) formulation composed of all macronutrients, including dextrose, amino acids, and intravenous fat emulsions (IVFE), in one bag. The TNA may be safely administered to the patient, with all components aseptically compounded and minimal administration manipulation required, lending itself to decreases in risks of catheter contamination and patient infections. The TNA is compatible and stable at recommended concentrations, and since the IVFE is in the TNA, it is infused at slower rates, allowing for better fat clearance.
