Building Bridges to Overcome Widening Gaps: Challenges in Addressing the Need for Professional Preparation of Infant-Toddler Practitioners in Higher Education

As the professional qualifications for those working with infants, toddlers, and their families continue to expand, institutes of higher education (IHEs) play an increasingly vital role in training the infant/toddler workforce. However, IHEs face numerous programming and pedagogical issues that make meeting the needs of these professionals difficult. These issues are further complicated by persistent challenges within early care and education. In this paper, we examine these issues in detail and discuss the Collaborative for Understanding the Pedagogy of Infant/toddler Development (CUPID), a cross-institution partnership working to enhance the quality of infant/toddler professional preparation in higher education

Prevalence and psychosocial risk factors of depression in a group of older adults in Bogota

prevalencia se ha descrito entre 1,2 a 12% en mayores que viven en comunidad. Objetivo: estimar la prevalencia de depresión en un muestra de adultos mayores de Bogotá y describir los factores de riesgo psicosocial asociados. Material y métodos: se realizó un estudio de corte transversal observacional-descriptivo, en 889 adultos mayores autónomos. La depresión fue evaluada con el test de depresión geriátrica Yesavage y los factores de riesgo con la sección de acontecimientos vitales del cuestionario Predict. Resultados: el 74% de la muestra estuvo constituida por mujeres, la media de edad fue de 72,51 (DS 9,4) años y la escolaridad promedio en años fue de 7,50 (DS 5,64). Así mismo, se estimó una prevalencia de depresión del 18,6%, siendo mayor en mujeres (20%) y (18%) en sujetos entre 70 y 79 años, los adultos con baja escolaridad sumaron un 43%, y el 22% lo constituyeron personas dependientes económicamente. Por otra parte, se encontró relación entre la depresión y cinco de los factores de riesgo psicosocial conocidos como acontecimientos vitales adversos: insomnio, vivir solo, padecer enfermedades crónicas, haber sufrido una crisis económica, y la muerte de un familiar o amigo cercano en el último año. Conclusión: la prevalencia de depresión en un grupo de personas mayores de la comunidad en Bogotá es más alta que lo descrito previamente en Colombia y por la Organización Mundial de la Salud (OMS). Programas que reduzcan la soledad en la vejez y protejan a la mujer y a los mayores con menos escolaridad podrían mitigar esta condición.Introduction: depression is one of the most prevalent diseases in the elderly. In Colombia, the prevalence of depression in this population ranges from 1,2 to 12%. Objective: to estimate the prevalence of depression in a group of independent elderly subjects in Bogota and describe the psychosocial risk factors associated with it. Material and methods: a cross-observational and descriptive study was done. The sample was constituted of 889 autonomous elderly subjects of Bogota city. Depression was assessed by applying the Test of Geriatric Depression-Yesavage-. Besides, the psychosocial risk factors were measured through the life events section, which is part of the Predict Questionnaire. Results: 74% of the sample was made up of women, the mean age was 72,51 years old (DS.9,4) and the average of education was of 7.50 years (DS.5,64). Besides, it was found a prevalence of depression of 18,6%. This prevalence was higher in the women (20%) and elderly between 70 and 79 years old (18%), adults with low education with 43% or 22% in economically dependent people. A relationship between depression and five psychosocial risk factors, known as adverse life events-insomnia, living alone, suffering a chronic disease or economic crisis or the death of the couple, a close friend or a relative. Conclusion: results showed a higher prevalence of depression in this sample in comparison to the findings yielded in previous studies developed in Colombia and the WHO. Programs that help to reduce the long lines protect women and older with less schooling ageing could mitigate the condition

The quality of maternal secure-base scripts predicts children's secure-base behavior at home in three sociocultural groups

The secure-base phenomenon is central to the Bowlby/Ainsworth theory of attachment and is also central to the assessment of attachment across the lifespan. The present study tested whether mothers’ knowledge about the secure-base phenomenon, as assessed using a recently designed wordlist prompt measure for eliciting attachment-relevant stories, would predict their children’s securebase behavior, as assessed by observers in the home and summarized with the Attachment Q-set (AQS). In each of three sociocultural groups (from Colombia, Portugal, and the US), scores characterizing the quality of maternal secure-base narratives elicited using the word-list prompt procedure were internally consistent, as indicated by tests of cross-story reliability, and they were positively and significantly associated with the child’s security score from the AQS for each subsample. The correlation in the combined sample was r(129) = .33, p < .001. Subsequent analyses with the combined sample evaluated the AQS item-correlates of the secure-base script score. These analyses showed that mothers whose stories indicate that they have access to and use a positive secure-base script in their story production have children who treat them as a “secure base” at home. These results suggest that a core feature of adult attachment models, in each of the three sociocultural groups studied, is access to a secure-base script. Additional results from the study indicate that cross-language translations of the maternal narratives can receive valid, reliable scores even when evaluated by non-native speakers

Generation and integrated analysis of advanced patient-derived orthoxenograft models (PDOX) for the rational assessment of targeted therapies in endometrial cancer

Clinical management of endometrial cancer (EC) is handicapped by the limited availability of second line treatments and bona fide molecular biomarkers to predict recurrence. These limitations have hampered the treatment of these patients, whose survival rates have not improved over the last four decades. The advent of coordinated studies such as The Cancer Genome Atlas Uterine Corpus Endometrial Carcinoma (TCGA_UCEC) has partially solved this issue, but the lack of proper experimental systems still represents a bottleneck that precludes translational studies from successful clinical testing in EC patients. Within this context, the first study reporting the generation of a collection of endometrioid-EC-patient-derived orthoxenograft (PDOX) mouse models is presented that is believed to overcome these experimental constraints and pave the way toward state-of-the-art precision medicine in EC. The collection of primary tumors and derived PDOXs is characterized through an integrative approach based on transcriptomics, mutational profiles, and morphological analysis; and it is demonstrated that EC tumors engrafted in the mouse uterus retain the main molecular and morphological features from analogous tumor donors. Finally, the molecular properties of these tumors are harnessed to assess the therapeutic potential of trastuzumab, a human epidermal growth factor receptor 2 (HER2) inhibitor with growing interest in EC, using patient-derived organotypic multicellular tumor spheroids and in vivo experiments

A factorial randomized controlled trial to evaluate the effect of micronutrients supplementation and regular aerobic exercise on maternal endothelium-dependent vasodilatation and oxidative stress of the newborn

<p>Abstract</p> <p>Background</p> <p>Many studies have suggested a relationship between metabolic abnormalities and impaired fetal growth with the development of non-transmissible chronic diseases in the adulthood. Moreover, it has been proposed that maternal factors such as endothelial function and oxidative stress are key mechanisms of both fetal metabolic alterations and subsequent development of non-transmissible chronic diseases. The objective of this project is to evaluate the effect of micronutrient supplementation and regular aerobic exercise on endothelium-dependent vasodilation maternal and stress oxidative of the newborn.</p> <p>Methods and design</p> <p>320 pregnant women attending to usual prenatal care in Cali, Colombia will be included in a factorial randomized controlled trial. Women will be assigned to the following intervention groups: <it>1. Control group: </it>usual prenatal care (PC) and placebo (maltodextrine). <it>2.

Repositioning of the global epicentre of non-optimal cholesterol

High blood cholesterol is typically considered a feature of wealthy western countries(1,2). However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world(3) and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health(4,5). However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol-which is a marker of cardiovascular riskchanged from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million-4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.Peer reviewe

MoCA and MMSE scores in patients with mild cognitive impairment and dementia in a memory clinic in Bogotá

Introducción. Diferentes pruebas neuropsicológicas permiten explorar las funciones cognitivas del adulto mayor, en un tiempo corto. En Colombia se dispone de pocos estudios sobre puntuaciones y puntos de corte para el MMSE y para el MoCA en relación al diagnóstico de deterioro cognitivo. Objetivo. Describir la distribución de las puntuaciones del MMSE y el MoCA y los puntos de corte con mejor discriminación, para el diagnóstico de deterioro cognitivo leve y demencia, en una muestra de pacientes de Bogotá. Material y métodos. Se evaluaron 248 pacientes por un equipo multidisciplinario, que consultaron a la Clínica de Memoria del HIUSJ entre 2009-2012, siguiendo un protocolo establecido. Se identificaron las puntuaciones del MoCA y MMSE, que permitieron obtener el mayor porcentaje de pacientes correctamente clasificados. Resultados. En el 70% de los pacientes con DCL y en el 69 % de los sujetos normales, se encontraron puntuaciones del MMSE inferiores o iguales a 28. En 91% de pacientes con DCL y 84% de los sujetos normales, se presentaron puntuaciones del MoCA inferiores o iguales a 25. Los pacientes con cualquier tipo de demencia, presentaron puntuaciones del MMSE inferiores o iguales a 27 e inferiores o iguales a 24 en el MoCA. Conclusión. Según el presente estudio, el tamizaje de funciones cognitivas, utilizando el MoCA, clasifica de manera más acertada que el MMSE, a los sujetos con deterioro cognitivo. Creemos que en atención primaria, estos puntos deIntroduction. Some cognitive tests allow the evaluation of cognitive functions on the elderly in a short period of time. There are few studies in Colombia about cut-off point for the MMSE and the MoCA test. Objectives. To describe the distribution on scores on MMSE and MoCA test and the cut-off point with a better discrimination criteria for the diagnosis of mild cognitive impairment and dementia, in a sample of patients from Bogotá. Materials and Methods. Two hundred forty eight patients were included in this study, being evaluated by a multidisciplinary team that followed an established protocol, on patients who attended to the Memory Clinic of HIUSJ between 2009-2012. MoCA test and MMSE scores that allow higher percentages of correctly classified patients were identified. Results. Seventy percent of patients with mild cognitive impairment and 69% of normal individuals had scores on MMSE below or equal to 28. Ninety-one percent of patients with MCI and 89% of normal patients, had scores below or equal to 25. Patients with any type of dementia had scores on MMSE below or equal to 27 and below or equal to 24 in MoCA test. Conclusion. According to the study, the screening of cognitive functions, using MoCA test, is more accurate than MMSE in patients with cognitive decline. The cut-off points, identified in our study, can be considered useful until now in primary attention, in patients with a high level of education

Modulation of the Biocatalytic Properties of a Novel Lipase from Psychrophilic Serratia sp. (USBA-GBX-513) by Different Immobilization Strategies

In this work, the effect of different immobilization procedures on the properties of a lipase obtained from the extremophilic microorganism Serratia sp. USBA-GBX-513, which was isolated from Paramo soils of Los Nevados National Natural Park (Colombia), is reported. Different Shepharose beads were used: octyl-(OC), octyl-glyoxyl-(OC-GLX), cyanogen bromide (BrCN)-, and Q-Sepharose. The performance of the different immobilized extremophile lipase from Serratia (ESL) was compared with that of the lipase B from Candida antarctica (CALB). In all immobilization tests, hyperactivation of ESL was observed. The highest hyperactivation (10.3) was obtained by immobilization on the OC support. Subsequently, the thermal stability at pH 5, 7, and 9 and the stability in the presence of 50% (v/v) acetonitrile, 50% dioxane, and 50% tetrahydrofuran solvents at pH 7 and 40 °C were evaluated. ESL immobilized on octyl-Sepharose was the most stable biocatalyst at 90 °C and pH 9, while the most stable preparation at pH 5 was ESL immobilized on OC-GLX-Sepharose supports. Finally, in the presence of 50% (v/v) tetrahydrofuran (THF) or dioxane at 40 °C, ESL immobilized on OC-Sepharose was the most stable biocatalyst, while the immobilized preparation of ESL on Q-Sepharose was the most stable one in 40% (v/v) acetonitrile
