Expectativas y percepciones de la madre respecto a su recién-nacido: aplicación del inventario de percepción neonatal de broussard

OBJECTIVES: To evaluate Broussard's Neonatal Perception Inventory (BPNI), an instrument to measure the mother's perception and expectations regarding her newborn infant at immediate postpartum and one month afterwards in primiparous and multiparous women. METHODS: Prospective cohort of 27 multiparous and 29 primiparous mothers of healthy newborn infants. In the second day postpartum, mothers were asked about the difficulties they thought that babies would offer regarding specific behaviors: crying, spitting, feeding, elimination, sleeping and predictability. Answers were rated in a 5-point scale. Next, mothers were questioned about their own babies regarding the same items. After 30 days, the mothers were questioned again about her perception of most babies and their own baby regarding the same items. The results were analyzed by repeated measures ANOVA considering the following main effects: time, group (primiparous and mul-tiparous), and subjects (mother's baby and most babies). RESULTS: Following birth, mothers expected their babies to have fewer difficulties in the daily activities than the ma-jority of the babies. These expectations were confirmed one month later for all items. There were no differences between primiparous and multiparous mothers. CONCLUSIONS: The Broussard's Neonatal Perception In-ventory was well understood and accepted by mothers and showed consistent results in this study. It can be used as a screening psychological tool to assess bonding between mothers and infants.OBJETIVOS: Analizar el Inventario de Percepción Neonatal de Broussard (BNPI - un instrumento que detecta las percepciones y expectativas maternas respecto a los hijos) enseguida al parto (T1) y con un mes de vida (T2), en puér-peras multíparas y primíparas. MÉTODOS: Coorte prospectiva con 27 multíparas y 29 primíparas madres de neonatos a término sanos. Se preguntó a la madre en T1 la dificultad que ella esperaba que la mayoría de los bebés tuviera respecto a llorar, alimentarse, regurgitar o vomitar, evacuar, dormir y tener una rutina. Las respuestas fueron marcadas en una escala de 5 puntos. Enseguida, se repitieron las preguntas respecto a su hijo recién-nacido. En T2, se preguntaba a la madre la dificultad que ella creía que la mayoría de los bebés y su propio hijo presentaban respecto a los mismos requisitos. El análisis estadístico utilizó ANOVA para medidas repetidas, teniendo en cuenta los siguientes efectos principales: tiempo (T1 y T2), grupo (primíparas y multíparas) y categoría (su bebé y la mayoría de los bebés). RESULTADOS: Enseguida al parto, las madres esperaban que sus hijos tuvieran menos dificultad en las actividades evaluadas que la mayoría de los bebés. Esta expectativa se confirmó con 30 días de vida para todos los comportamientos. No hubo diferencias entre primíparas y multíparas. CONCLUSIONES: El BNPI fue bien atendido y aceptado por las madres, mostrando resultados consistentes en este estudio. El instrumento puede ser útil para seleccionar pares madre-bebé con dificultades en el establecimiento de vínculo.OBJETIVOS: Analisar o Inventário de Percepção Neonatal de Broussard, um instrumento que detecta as percepções e expectativas maternas com respeito aos filhos logo após o parto (Tempo 1) e com um mês de vida (Tempo 2), em puérperas multíparas e primíparas. MÉTODOS: Coorte prospectiva com 27 multíparas e 29 primíparas mães de neonatos a termo saudáveis.

Empleo de la fotografía en la diagnosis de un paisaje de interés cultural, la vega de Granada

La fotografía del paisaje es un instrumento de análisis fundamental para la diagnosis de los territorios. Todo paisaje cuenta con valores objetivos y otros subjetivos vinculados a su percepción, entre los que se encuentra los de carácter cultural, que si además cuentan con valor patrimonial lo hacen merecedor de protección específica por su interés. La fotografía es una herramienta adecuada para el análisis de los elementos de cualificación patrimonial del paisaje, del estado de los conflictos que les afectan, y para el descubrimiento de las oportunidades para su preservación. Las series de fotografías aéreas aportan importantes datos sobre la evolución de los usos en el territorio, de las zonas límites de contacto y de la permanencia o desaparición de los elementos de valor en la caracterización cultural. Siendo necesarias las comprensiones territorial, integral, transversal y escalar de estos paisajes culturales de interés, en los agrarios que aún conservan su funcionalidad debe considerarse también su dinámica cambiante. La Vega de Granada es un ejemplo de paisaje agrario de interés cultural dinámico inmerso en una aglomeración urbana, razón de ser y origen de la misma, soporte de su sociedad e historia, cuyo valor patrimonial es reivindicado cada vez con mayor fuerza a la vez que su preservación es más precaria, acosado por el avance indiscriminado de usos no agrarios que lo han fragmentado y devaluado de manera significativa en las últimas décadas. En el estudio de este paisaje resulta fundamental desde el punto de vista metodológico el empleo de fotografías que hacen comprender la evolución producida, siendo especialmente útil su empleo en la comprensión de los nuevos conflictos producidos desde el último tercio del siglo XX.The landscape photography is a fundamental tool of analysis in order to diagnose territories. Every landscape has its objective and subjective values linked to perception. Amongst them, it is relevant to remember that if the cultural one involves a heritage value, then the landscape is worth of a specific protection. Thus, the photography is an adequate tool for the analysis of the heritage elements in the landscape, of the state of the conflicts that affect them and in order to find the opportunities to its preservation. The series of aerial photographs provide important information about the evolution of the uses in the territory, their borders of connection and the continuity or disappearance of the values in the cultural qualification. It is necessary an approach in a territorial, comprehensive, cross-cutting and pluri-scale way to these cultural landscapes of interest. In the agrarian ones which still conserve its functionalities, it must also be considered its dynamic reality. The Vega of Granada is an example of a dynamic agrarian landscape of cultural interest in the midst of urban agglomerations. This condition is in its origin, in its raison d’être and in the explanation of its society and its history. That is why the heritage value is more every day reclaimed while its preservation is every time more uncertain because of the indiscriminate progress of the non-agrarian uses which have significantly fragmented and devaluated the landscape during these last decades. In the methodology of this landscape study has been essential the use of photographs in order to understand the evolution, and it has been particularly useful to figure out the new conflicts originated in the last third of the 20th Century

International scientific research on venture capital: a bibliometric and mapping analysis from the period 1978–2020

The aim of this study is to explore the relevance of scientific production on venture capital using bibliometric and mapping tools.We performed a search in Scopus, involving any document published between 1978 and 2020. We used bibliometric indicators to explore documents production, dispersion, distribution, time of duplication, and annual growth, as Price’s law of scientific literature growth, Lotka’s law, the transient index, and the Bradford model. We also calculated the participation index of the different countries and institutions. Finally, we explored the co-occurrence and thematic networks for the most frequently used terms in venture capital research through bibliometric mapping.A total of 1,230 original articles were collected from the timeframe 1978–2020. The model confirms that Price’s law is not fulfilled. Scientific production was better adjusted to linear growth (r = 0.9290) than exponential (r = 0.9161). Literature on venture capital research has increased its growth in the last 43 years at a rate of 7.9% per year, with a production that doubles its size every 9.1 years. The transience index was 79.91%, which indicates that most of the scientific production is due to a lot of authors with a small number of publications on the research topic. Bradford´s law shows that the scientific production in this area is widely distributed in multiple journals, and Lotka’s law indicates that the author’s distribution is heavily concentrated on small producers. The United States of America (USA) and the University of Pennsylvania present the highest production, contributing 31.22% and 1.63% of the total production of research on venture capital.The venture capital task has undergone a linear growth, with a very high rate of transience, which indicates the presence of numerous authors who sporadically publish on this topic. No evidence of a saturation point was observed in the scientific production analyzed, which makes it possible to conclude that the research in venture capital will continue to be in demand by the scientific community.The aim of this study is to explore the relevance of scientific production on venture capital using bibliometric and mapping tools.We performed a search in Scopus, involving any document published between 1978 and 2020.

Comparison of zebrafish and mice knockouts for Megalencephalic Leukoencephalopathy proteins indicates that GlialCAM/MLC1 forms a functional unit

Background: Megalencephalic Leukoencephalopathy with subcortical Cysts (MLC) is a rare type of leukodystrophy characterized by astrocyte and myelin vacuolization, epilepsy and early-onset macrocephaly. MLC is caused by mutations in MLC1 or GLIALCAM, coding for two membrane proteins with an unknown function that form a complex specifically expressed in astrocytes at cell-cell junctions. Recent studies in Mlc1-/- or Glialcam-/- mice and mlc1-/- zebrafish have shown that MLC1 regulates glial surface levels of GlialCAM in vivo and that GlialCAM is also required for MLC1 expression and localization at cell-cell junctions. Methods: we have generated and analysed glialcama-/- zebrafish. We also generated zebrafish glialcama-/- mlc1-/- and mice double KO for both genes and performed magnetic resonance imaging, histological studies and biochemical analyses. Results: glialcama-/- shows megalencephaly and increased fluid accumulation. In both zebrafish and mice, this phenotype is not aggravated by additional elimination of mlc1. Unlike mice, mlc1 protein expression and localization are unaltered in glialcama-/- zebrafish, possibly because there is an up-regulation of mlc1 mRNA. In line with these results, MLC1 overexpressed in Glialcam-/- mouse primary astrocytes is located at cell-cell junctions. Conclusions: this work indicates that the two proteins involved in the pathogenesis of MLC, GlialCAM and MLC1, form a functional unit, and thus, that loss-of-function mutations in these genes cause leukodystrophy through a common pathway

Disrupting MLC1 and GlialCAM and ClC-2interactions in leukodystrophy entails glial chloridechannel dysfunction

Defects in the astrocytic membrane protein MLC1, the adhesion molecule GlialCAM or the chloride channel ClC-2 underlie human leukoencephalopathies. Whereas GlialCAM binds ClC-2 and MLC1, and modifies ClC-2 currents in vitro, no functional connections between MLC1 and ClC-2 are known. Here we investigate this by generating loss-of-function Glialcam and Mlc1 mouse models manifesting myelin vacuolization. We find that ClC-2 is unnecessary for MLC1 and GlialCAM localization in brain, whereas GlialCAM is important for targeting MLC1 and ClC-2 to specialized glial domains in vivo and for modifying ClC-2's biophysical properties specifically in oligodendrocytes (OLs), the cells chiefly affected by vacuolization. Unexpectedly, MLC1 is crucial for proper localization of GlialCAM and ClC-2, and for changing ClC-2 currents. Our data unmask an unforeseen functional relationship between MLC1 and ClC-2 in vivo, which is probably mediated by GlialCAM, and suggest that ClC-2 participates in the pathogenesis of megalencephalic leukoencephalopathy with subcortical cysts

Lithium carbonate in amyotrophic lateral sclerosis patients homozygous for the C-allele at SNP rs12608932 in UNC13A: protocol for a confirmatory, randomized, group-sequential, event-driven, double-blind, placebo-controlled trial

BackgroundGiven the large genetic heterogeneity in amyotrophic lateral sclerosis (ALS), it seems likely that genetic subgroups may benefit differently from treatment. An exploratory meta-analysis identified that patients homozygous for the C-allele at SNP rs12608932, a single nucleotide polymorphism in the gene UNC13A, had a statistically significant survival benefit when treated with lithium carbonate. We aim to confirm the efficacy of lithium carbonate on the time to death or respiratory insufficiency in patients with ALS homozygous for the C-allele at SNP rs12608932 in UNC13A. MethodsA randomized, group-sequential, event-driven, double-blind, placebo-controlled trial will be conducted in 15 sites across Europe and Australia. Patients will be genotyped for UNC13A; those homozygous for the C-allele at SNP rs12608932 will be eligible. Patients must have a diagnosis of ALS according to the revised El Escorial criteria, and a TRICALS risk-profile score between -6.0 and -2.0. An expected number of 1200 patients will be screened in order to enroll a target sample size of 171 patients. Patients will be randomly allocated in a 2:1 ratio to lithium carbonate or matching placebo, and treated for a maximum duration of 24 months. The primary endpoint is the time to death or respiratory insufficiency, whichever occurs first. Key secondary endpoints include functional decline, respiratory function, quality of life, tolerability, and safety. An interim analysis for futility and efficacy will be conducted after the occurrence of 41 events. DiscussionLithium carbonate has been proven to be safe and well-tolerated in patients with ALS. Given the favorable safety profile, the potential benefits are considered to outweigh the burden and risks associated with study participation. This study may provide conclusive evidence about the life-prolonging potential of lithium carbonate in a genetic ALS subgroup

Screening and diagnostic breast MRI: how do they impact surgical treatment? Insights from the MIPA study

Objectives: To report mastectomy and reoperation rates in women who had breast MRI for screening (S-MRI subgroup) or diagnostic (D-MRI subgroup) purposes, using multivariable analysis for investigating the role of MRI referral/nonreferral and other covariates in driving surgical outcomes. Methods: The MIPA observational study enrolled women aged 18–80 years with newly diagnosed breast cancer destined to have surgery as the primary treatment, in 27 centres worldwide. Mastectomy and reoperation rates were compared using non-parametric tests and multivariable analysis. Results: A total of 5828 patients entered analysis, 2763 (47.4%) did not undergo MRI (noMRI subgroup) and 3065 underwent MRI (52.6%); of the latter, 2441/3065 (79.7%) underwent MRI with preoperative intent (P-MRI subgroup), 510/3065 (16.6%) D-MRI, and 114/3065 S-MRI (3.7%). The reoperation rate was 10.5% for S-MRI, 8.2% for D-MRI, and 8.5% for P-MRI, while it was 11.7% for noMRI (p ≤ 0.023 for comparisons with D-MRI and P-MRI). The overall mastectomy rate (first-line mastectomy plus conversions from conserving surgery to mastectomy) was 39.5% for S-MRI, 36.2% for P-MRI, 24.1% for D-MRI, and 18.0% for noMRI. At multivariable analysis, using noMRI as reference, the odds ratios for overall mastectomy were 2.4 (p < 0.001) for S-MRI, 1.0 (p = 0.957) for D-MRI, and 1.9 (p < 0.001) for P-MRI. Conclusions: Patients from the D-MRI subgroup had the lowest overall mastectomy rate (24.1%) among MRI subgroups and the lowest reoperation rate (8.2%) together with P-MRI (8.5%). This analysis offers an insight into how the initial indication for MRI affects the subsequent surgical treatment of breast cancer. Key Points: • Of 3065 breast MRI examinations, 79.7% were performed with preoperative intent (P-MRI), 16.6% were diagnostic (D-MRI), and 3.7% were screening (S-MRI) examinations. • The D-MRI subgroup had the lowest mastectomy rate (24.1%) among MRI subgroups and the lowest reoperation rate (8.2%) together with P-MRI (8.5%). • The S-MRI subgroup had the highest mastectomy rate (39.5%) which aligns with higher-than-average risk in this subgroup, with a reoperation rate (10.5%) not significantly different to that of all other subgroups

Colocalized Structural and Functional Changes in the Cortex of Patients with Trigeminal Neuropathic Pain

Background: Recent data suggests that in chronic pain there are changes in gray matter consistent with decreased brain volume, indicating that the disease process may produce morphological changes in the brains of those affected. However, no study has evaluated cortical thickness in relation to specific functional changes in evoked pain. In this study we sought to investigate structural (gray matter thickness) and functional (blood oxygenation dependent level – BOLD) changes in cortical regions of precisely matched patients with chronic trigeminal neuropathic pain (TNP) affecting the right maxillary (V2) division of the trigeminal nerve. The model has a number of advantages including the evaluation of specific changes that can be mapped to known somatotopic anatomy. Methodology/Principal Findings: Cortical regions were chosen based on sensory (Somatosensory cortex (SI and SII), motor (MI) and posterior insula), or emotional (DLPFC, Frontal, Anterior Insula, Cingulate) processing of pain. Both structural and functional (to brush-induced allodynia) scans were obtained and averaged from two different imaging sessions separated by 2–6 months in all patients. Age and gender-matched healthy controls were also scanned twice for cortical thickness measurement. Changes in cortical thickness of TNP patients were frequently colocalized and correlated with functional allodynic activations, and included both cortical thickening and thinning in sensorimotor regions, and predominantly thinning in emotional regions. Conclusions: Overall, such patterns of cortical thickness suggest a dynamic functionally-driven plasticity of the brain. These structural changes, which correlated with the pain duration, age-at-onset, pain intensity and cortical activity, may be specific targets for evaluating therapeutic interventions
