Normative Anthropometric and Physical-Function Scores for Costa Rican Older Adults

INTRODUCTION: The aging population is becoming significantly large in several countries due to improved health conditions and higher life expectancy. For instance, Costa Rican elderly have 17% less mortality at 90 yr. of age than elderly from high-income countries, and in Costa Rica life expectancy is higher for men than for women. In developed countries such as Spain, a large number of sedentary elderly have been found with elevated body fat percentage, which might impact their overall health and quality of life. Although the international scientific literature is extensive, the physical and functional status of Central American elderly is unknown. PURPOSE: The purpose of the study was to construct normative scores for anthropometric, adiposity and upper-arm strength variables in Costa Rican adults aged 60 to 110 yr. METHODS: Participants were 5494 Costa Rican elderly randomly selected from the Costa Rican National Population Census. These participants were assessed to determine their general health status and to obtain anthropometric, adiposity and hand grip strength measures. RESULTS: Nearly 50% of males and females showed an increased risk of metabolic complications (χ2 = 91.6; p ≤ 0.001). A higher percentage of females (64.5%) had abdominal obesity compared to males (18.6%). Males (39.8%) were more pre-obese than females (37.2%) and also type II obesity was more frequent in males (3.8%) than in females (3.5%). Males had higher body weight (4.4%) than females (3.9%), less type I obesity (13.4%) than women (17.5%) and less type III obesity (1.0%) than females (1.5%). Gender specific percentile-based norms (P10th, P25th, P50th, P75th, and P90th) were derived from data collected for each 10-year age groups (60-69, 70-79, 80-89, 90-99, and ≥100). CONCLUSION: This is the first population-based study in Central America reporting normative scores for anthropometric and physical-function variables in older adults

Life Project for Adolescents: A Concept Analysis

It is essential to identify protective factors during adolescence due to its high incidence on risk behaviors. One of these factors is to have a life project that influences adolescent decision-making. The concept of life project has mainly been linked to teen pregnancy, depression and suicide; however, some authors agree that the concept is not clearly defined. Therefore, the objective of this paper is to define the concept of adolescent life project, using the methodology developed by Walker and Avant for concept analysis. The following steps were followed are: select a concept, determining the purpose of analysis, identifying all uses of the concept, determining the defining attributes, identifying a model, a borderline and a contrary cases, identifying history and consequences of the concept, and finally defining empirical referents. After the analysis, the final definition of the concept of adolescent life project includes the set of desires, future plans and actions necessary to accomplish it that influence the adolescent decisions. Knowing the importance of this concept when working with adolescents may guide development more effective interventions

Time periodicity and dynamical stability in two-boson systems

We calculate the period of recurrence of dynamical systems comprising two interacting bosons. A number of theoretical issues related to this problem are discussed, in particular, the conditions for small periodicity. The knowledge gathered in this way is then used to propose a notion of dynamical stability based on the stability of the period. Dynamical simulations show good agreement with the proposed scheme. We also apply the results to the phenomenon known as coherent population trapping and find stability conditions in this specific case.Comment: 7+ pages, 5 figure

A new species of pitviper of the genus Bothrops (Serpentes: Viperidae: Crotalinae) from the Central Andes of South America

We describe a new species of montane pitviper of the genus Bothrops from the Cordillera Oriental of the Central Andes, distributed from southern Peru to central Bolivia. The new species can be distinguished from its congeners by the characteristic combination of a dorsal body color pattern consisting of triangular or subtriangular dark brown dorsal blotches, paired dark brown parallel occipital stripes, a conspicuous dark brown postocular stripe, the presence of canthorostrals in some specimens, prelacunal fused or partially fused with second supralabial, one scale usually separating internasals, rostral trapezoidal, two canthals oval to rounded, similar size or slightly larger than internasals, three or four medial intercanthals, eight to twelve intersupraoculars, intercanthals and intersupraoculars keeled and frequently slightly keeled, supraoculars oval, one to three suboculars, two to three postoculars, loreal subtriangular, two to six prefoveals, subfoveals absent, two or none postfoveals, one or two scales between suboculars and fourth supralabial, seven or eight supralabials, nine or eleven infralabials, 23-25 middorsal scales, 189-195 ventrals in females and 182-190 in males, 48-58 subcaudals in females and 54-63 in males, exceptionally undivided. The new species is apparently restricted to areas within Andean montane forests that are less humid and devoid of large trees.Fil: Timms, J..

UNMASC: Tumor-only variant calling with unmatched normal controls

Despite years of progress, mutation detection in cancer samples continues to require significant manual review as a final step. Expert review is particularly challenging in cases where tumors are sequenced without matched normal control DNA. Attempts have been made to call somatic point mutations without a matched normal sample by removing well-known germline variants, utilizing unmatched normal controls, and constructing decision rules to classify sequencing errors and private germline variants. With budgetary constraints related to computational and sequencing costs, finding the appropriate number of controls is a crucial step to identifying somatic variants. Our approach utilizes public databases for canonical somatic variants as well as germline variants and leverages information gathered about nearby positions in the normal controls. Drawing from our cohort of targeted capture panel sequencing of tumor and normal samples with varying tumortypes and demographics, these served as a benchmark for our tumor-only variant calling pipeline to observe the relationship between our ability to correctly classify variants against a number of unmatched normals. With our benchmarked samples, approximately ten normal controls were needed to maintain 94% sensitivity, 99% specificity and 76% positive predictive value, far outperforming comparable methods. Our approach, called UNMASC, also serves as a supplement to traditional tumor with matched normal variant calling workflows and can potentially extend to other concerns arising from analyzing next generation sequencing data

Microglial Activation in the Retina of a Triple-Transgenic Alzheimer’s Disease Mouse Model (3xTg-AD)

Alzheimer’s disease (AD) is the most common type of dementia in the world. The main biomarkers associated with AD are protein amyloid-β (Aβ) plaques and protein tau neurofibrillary tangles, which are responsible for brain neuroinflammation mediated by microglial cells. Increasing evidence has shown that the retina can also be affected in AD, presenting some molecular and cellular changes in the brain, such as microglia activation. However, there are only a few studies assessing such changes in the retinal microglia in animal models of AD. These studies use retinal sections, which have some limitations. In this study, we performed, for the first time in a triple-transgenic AD mouse model (3xTg-AD), a quantitative morphometric analysis of microglia activation (using the anti-Iba-1 antibody) in retinal whole-mounts, allowing visualization of the entire microglial cell, as well as its localization along the extension of the retina in different layers. Compared to age-matched animals, the retina of 3xTg-AD mice presents a higher number of microglial cells and a thicker microglial cell body area. Moreover, the microglia migrate, reorient, and retract their processes, changing their localization from a parallel to a perpendicular position relative to the retinal surface. These findings demonstrate clear microglia remodeling in the retina of 3xTg-AD mice

ABSTRACT Introduction: chronic noncommunicable  diseases cause high morbidity and mortality worldwide so it requires innovative strategies that impact on self-care, adoption of healthy lifestyles and the diseases treatment. Nowadays, the information and communication technologies compose a resource in order to improve the effectiveness and efficiency of the patient’s programs with chronic diseases, overcome structural limitations and the availability of human resources in the health system. Objective: to evaluate the impact of theinformation and communication technologies to promote healthy lifestyles and adherence to medication, to know the perception of users about the usefulness of the intervention and also their effect on clinical variables. Methods: longitudinal study, in which 90 patients outpatient health institution in Manizales were included to receive text messages, was made. There were chosen over-age-18 men and women, with arterial hypertension diagnosis or diabetes mellitus who owned a cell phone or were with a near carer assistant who would accept receiving text massages in its own mobile. The massages were about their healthy lifestyle, and these were sent between august and december during 29 weeks. 68 subject completed the follow up. At the end of the intervention, acceptance, usefulness and effects on laboratory and clinical parameters were evaluated. Results: it was found that 100% of the patients who confirmed receiving the messages perceived an improvement in self care; showing changes in diet (95.16%) and the amelioration of medication adherence (59%). Besides, the service utility was qualified as excellent. Conclusions: the patient’s perceptions about the use of the information and communication technologies was positive and it could generates changes in areas such as alimentary habits and medication adherence, in promoting healthy lifestyles and management of chronic noncommunicable diseases. However, it requires controlled studies using a standardized long-term monitoring to determine the actual impact on clinical variables and cost-effective. In addition, it should identify the type of population would get greater benefit. MÉD.UIS. 2016;29(2):59-70.Keywords: Diabetes Mellitus. Hypertension. Primary prevention. Text Messaging. Cell Phones.

Identification of CFTR variants in Latino patients with cystic fibrosis from the Dominican Republic and Puerto Rico

BackgroundIn cystic fibrosis (CF), the spectrum and frequency of CFTR variants differ by geography and race/ethnicity. CFTR variants in White patients are wellâ described compared with Latino patients. No studies of CFTR variants have been done in patients with CF in the Dominican Republic or Puerto Rico.MethodsCFTR was sequenced in 61 Dominican Republican patients and 21 Puerto Rican patients with CF and greater than â â â â 60â mmol/L sweat chloride. The spectrum of CFTR variants was identified and the proportion of patients with 0, 1, or 2 CFTR variants identified was determined. The functional effects of identified CFTR variants were investigated using clinical annotation databases and computational prediction tools.ResultsOur study found 10% of Dominican patients had two CFTR variants identified compared with 81% of Puerto Rican patients. No CFTR variants were identified in 69% of Dominican patients and 10% of Puerto Rican patients. In Dominican patients, there were 19 identified CFTR variants, accounting for 25 out of 122 disease alleles (20%). In Puerto Rican patients, there were 16 identified CFTR variants, accounting for 36 out of 42 disease alleles (86%) in Puerto Rican patients. Thirty CFTR variants were identified overall. The most frequent variants for Dominican patients were p.Phe508del and p.Ala559Thr and for Puerto Rican patients were p.Phe508del, p.Arg1066Cys, p.Arg334Trp, and p.I507del.ConclusionsIn this first description of the CFTR variants in patients with CF from the Dominican Republic and Puerto Rico, there was a low detection rate of two CFTR variants after full sequencing with the majority of patients from the Dominican Republic without identified variants.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/153634/1/ppul24549.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/153634/2/ppul24549_am.pd
