The Use of Social Media to Promote Lab Medicine to Students, Patients, and the General Public.

Background: The clinical laboratory provides critical information by which medical decisions are made. However, few understand the effort and support required to deliver high-quality results. This has led to unfavorable federal legislation that threatens the ability of laboratorians to be innovative and advance the field.

Physical Activity in Public Parks of High and Low Socioeconomic Status in Colombia Using Observational Methods.

Background: Public parks are an important resource for the promotion of physical activity (PA). This is the first study in Colombia and the fourth in Latin America to describe the characteristics of park users and their levels of PA using objective measures.

Methods: A systematic observation assessed sex, age, and the level of PA of users of 10 parks in an intermediate-size city in Colombia, classified in low (5 parks) and high (5 parks) socioeconomic status (SES).

Individual and Environmental Correlates to Quality of Life in Park Users in Colombia.

To explore individual and environmental correlates to quality of life (QoL) in park users in Colombia. A cross-sectional study with face-to-face interviews was conducted with 1392 park users from ten parks in Colombia. The survey included sociodemographic questions, health condition assessed with EuroQuol-5-Dimensions-5-Levels; in addition, questions about accessibility to the parks and perceptions about quality of infrastructure and green areas were asked.

Limits of Resolution and Sensitivity of Proton Detected MAS Solid-State NMR Experiments at 111 kHz in Deuterated and Protonated Proteins.

MAS solid-state NMR is capable of determining structures of protonated solid proteins using proton-detected experiments. These experiments are performed at MAS rotation frequency of around 110 kHz, employing 0.5 mg of material.

[Reliability of a questionnaire for measuring physical activity and sedentary behavior in children from preschool to fourth grade].

Introduction: International recommendations for physical activity and time spent in sedentary behaviors for children in their early years require the availability of measuring instruments with psychometric properties that allow for the assessment of population dynamics and interventions to improve health.

Objective: To evaluate the reliability of a questionnaire to measure physical activity and sedentary behaviors in children from preschool to fourth grade.

Materials And Methods: One hundred and eight parents answered the questionnaire.

Effect of high-voltage electrical stimulation on the albumin and histamine serum concentrations, edema, and pain in acute joint inflammation of rats.

Background: The mechanism by which high-voltage electrical stimulation (HVPC) acts on edema reduction is unknown.

Objective: To assess the effect of HVPC with negative polarity (-) applied to the ankle of rats with acute joint inflammation.

Method: Sixty-four rats were divided into four groups (n=16): inflamed+HVPC(-), 0.

Results from Colombia's 2014 Report Card on Physical Activity for Children and Youth.

Background: Physical activity (PA) is central to the global agenda for the prevention on noncommunicable diseases (NCDs). Although 80% of NCDs occur in low-to-middle-income countries, the evidence on PA comes mainly from high-income countries. In this context, the report card for Colombia is an advocacy tool to help in the translation of evidence into concrete actions.

[Associated factors to availability and use of electronic media in children from preschool to 4th grade].

Introduction: The increased availability of electronic media has changed the behavior in children and young people by encouraging sedentary lifestile, with health effects from a very young age.

Objective: To characterize the availability and use of electronic media and its associated factors in children from preschool through 4 th grade.

Materials And Methods: A cross-sectional study with cluster sampling was carried out.

Effect of walking and resting after three cryotherapy modalities on the recovery of sensory and motor nerve conduction velocity in healthy subjects.

Background: Different cryotherapy modalities have distinct effects on sensory and motor nerve conduction parameters. However, it is unclear how these parameters change during the post-cooling period and how the exercise carried out in this period would influence the recovery of nerve conduction velocity (NCV).

Objectives: To compare the effects of three cryotherapy modalities on post-cooling NCV and to analyze the effect of walking on the recovery of sensory and motor NCV.

Effect of high-voltage pulsed current plus conventional treatment on acute ankle sprain.

Background: The effectiveness of high-voltage pulsed current (HVPC) treatments in humans as a means of controlling edema and post-traumatic pain has not yet been established.

Objective: To analyze the effects of HVPC plus conventional treatment on lateral ankle sprains.

Methods: This was a randomized, controlled, double-blind clinical trial with three intervention groups: CG (control group with conventional treatment); HVPC(-) group (conventional treatment plus negative polarity HVPC); HVPC+ group (conventional treatment plus positive polarity HVPC).

Motor and sensory nerve conduction are affected differently by ice pack, ice massage, and cold water immersion.

Background: It is well known that reducing tissue temperature changes sensory and motor nerve conduction. However, few studies have compared the effect of different cold modalities on nerve conduction parameters.

Objective: The purpose of this study was to compare the effects of ice pack, ice massage, and cold water immersion on the conduction parameters of the sural (sensorial) and tibial motor nerves.

Reliability of superficial peroneal, sural, and medial plantar nerve conduction studies: analysis of statistical methods.

Unlabelled: The reliability of medial plantar, sural, and superficial peroneal nerve conduction studies (NCS) has not been widely studied. These nerves are usually involved in distal sensory neuropathies and their serial study is relevant in the clinical setting.

Purpose: To determine the inter- and intrarater reliability of superficial peroneal, sural, and medial plantar NCS in healthy participants.

[Reliability and convergent construct validity of the abridged development scale and a Spanish translation of the Neurosensory Motor Development Assessment].

Introduction: Motor development is the acquisition and evolution of motor skills; its evaluation allows detection of abnormalities and permits a suitable opportunity for bringing them to medical attention. Several instruments have been designed to characterize motor development in early childhood, among them the Neurosensory Motor Development Assessment test. In Colombia, studies on the psychometric properties have not been published on any of these tests.
