Attachment styles of children in an inpatient ward of a psychiatric hospital

The aim of this study was to investigate the attachment styles of children between the ages of six and twelve years of age who were admitted as inpatients in a children’s ward of a psychiatric hospital. Attachment theory (Bowlby, 1997, 1998) proposes that children develop certain attachment styles towards their primary caregivers from birth through to three years of age, after which the styles remain relatively constant as can be seen through attachment behaviours later on in life. These attachment styles can be secure, insecure-ambivalent / anxious or insecure-avoidant (Ainsworth, Blehar, Waters&Wall, 1978). Green and Goldwyn (2002) also refer to a fourth category that was established through later research on attachment, named disorganised attachment. Psychiatric hospitalisation of a child implies the assumption of psychopathology and through institutionalisation, he or she is literally separated from the primary caregivers and inevitably placed in unfamiliar surroundings with strangers, making it an ideal setting to investigate attachment features. The researcher worked from the supposition that the mere fact of hospitalisation and implied pathology would thus point to insecure attachment styles in these children. A qualitative research design was implemented to gather information regarding the children’s attachment styles. Two projective techniques were used, namely the Children’s Apperception Test and the Picture Test of Separation and Individuation. Analysis of the information consisted of a first- and second-order process of thematic content analysis. The results yielded thirteen categories of experience. An extensive description of each category was provided, and the categories were then related to theory. The results obtained support previous research findings that found that institutionalised children tend to show more insecure attachment styles. The results from this study also indicated that these insecure attachment styles tend to be predominantly insecure-avoidant or insecure-disorganised.Dissertation (MA(Psychology))--University of Pretoria, 2007.Psychologyunrestricte

The role of diet and other environmental factors in the causation of gastric cancer in Iran—A population based study

Despite a declining trend in the incidence of gastric cancer (GC), it is still a major global public health concern of the 21st century. The rates of GC reported from Ardabil Province, Iran, are among the highest in the world. To investigate risk factors for GC in Ardabil, we undertook a population-based case-control study. The study aimed to recruit all Ardabil residents newly diagnosed with GC in the time period of 2004–2005, and 2 controls per case. Participants were interviewed using a structured questionnaire. Ten milliliters of blood was collected for blood grouping and investigating the presence of IgG antibodies against Helicobacter pylori. During the study period, 217 people with GC and 394 controls were recruited. In multivariate analysis, diet and Helicobacter pylori infection (OR 5 2.41; 95% CI: 1.35–4.32) were found to be the factors that were most strongly related to GC. High intake of Allium vegetables (OR 5 0.35) and fruit, especially citrus fruit (OR 5 0.31) and consumption of fresh fish (OR 5 0.37) were significantly protective. On the other hand, consumption of red meat (OR 5 3.40) and dairy products (OR 5 2.28) were positively associated with the risk of GC. People who had a preference for higher salt intake (OR 5 3.10) and drinking strong and hot tea (OR 5 2.64 and 2.85, respectively) were at higher risk. In conclusion, Helicobacter pylori infection as measured by serum IgG as well as the consumption of red meat and dairy products increases the risk of GC in Ardabil, while the intake of fresh fruit and fresh fish decrease the risk

Medidas de protección en violencia contra la mujer y el grupo familiar en los juzgados de familia de Lima-2017

La presente investigación tiene como propósito establecer si las medidas de protección son idóneas o no, con el fin de propiciar una protección efectiva a las mujeres e integrantes del grupo familiar que son víctimas de violencia, bajo el marco normativo de la ley N° 30364, por tal razón se entrevista, a los(as) jueces y a los(as) encargados de dar trámite a los procesos de violencia contra la mujer y los integrantes del grupo familiar en los juzgados de familia de Lima; es desarrollada mediante el método de estudio fenomenológico, pues este diseño tiene como centro de indagación las experiencias de los participantes, quienes vendrían a ser los jueces y encargados de dar trámite a los referidos procesos. Además, se tiene en consideración, que las medidas de protección se han emitido considerando la propia afirmación del agresor de haber ejercido violencia en sus diversas modalidades, de la incapacidad médico legal descrito en el certificado médico legal, de los protocolos de pericia psicológica, informes psicológicos, así como otros aspectos tales como los resultados de riesgo de la ficha de valoración de riesgo, las visitas sociales, así como tener un trato especial a las víctimas que son personas vulnerables; sin embargo existen situaciones en las que no se pueden dictar medidas correspondientes pues únicamente se cuenta con los hechos denunciados; en razón de que, no obran las evaluaciones practicadas que apoyen a la buena emisión de medidas de protección. Además, es necesario precisar que los institutos de medicina legal no entregan inmediata ni oportunamente los certificados correspondientes, no siendo las medidas actuadas idóneas para proteger a la víctima de violencia familiar. Por otro lado, se considera que las medidas de protección no se pueden dictar inmediatamente en razón del amplio deber procesal de los juzgados de familia y la no incorporación de un personal a partir de la ampliación de su competencia. Entonces, en razón de todo lo expuesto, existe la necesidad de recomendar la implementación de un protocolo que permita la protección inmediata y adecuada de las mujeres e integrantes del grupo familiar que son víctimas de violencia

Signal enhancement on gold nanoparticle-based lateral flow tests using cellulose nanofibers

Lateral flow paper-based biosensors merge as powerful tools in point-of-care diagnostics since they are cheap, portable, robust, selective, fast and easy to use. However, the sensitivity of this type of biosensors is not always as high as required, often not permitting a clear quantification. To improve the colorimetric response of standard lateral flow strips (LFs), we have applied a new enhancement strategy that increases the sensitivity of LFs based on the use of cellulose nanofibers (CNF). CNF penetrate inside the pores of LFs nitrocellulose paper, compacting the pore size only in the test line, particularly near the surface of the strip. This modification retains the bioreceptors (antibodies) close to the surface of the strips, and thus further increasing the density of selectively attached gold nanoparticles (AuNPs) in the top part of the membrane, in the test line area, only when the sample is positive. This effect boosts in average a 36.6% the sensitivity of the LFs. The optical measurements of the LFs were carried out with a mobile phone camera whose imaging resolution was improved by attaching microscopic lens on the camera objective. The characterization of CNF into paper and their effect was analyzed using atomic force microscope (AFM) and scanning electron microscope (SEM) imaging techniques

Amino Acids and IGF1 Regulation of Fish Muscle Growth Revealed by Transcriptome and microRNAome Integrative Analyses of Pacu (Piaractus mesopotamicus) Myotubes

Amino acids (AA) and IGF1 have been demonstrated to play essential roles in protein synthesis and fish muscle growth. The myoblast cell culture is useful for studying muscle regulation, and omics data have contributed enormously to understanding its molecular biology. However, to our knowledge, no study has performed the large-scale sequencing of fish-cultured muscle cells stimulated with pro-growth signals. In this work, we obtained the transcriptome and microRNAome of pacu (Piaractus mesopotamicus)-cultured myotubes treated with AA or IGF1. We identified 1228 and 534 genes differentially expressed by AA and IGF1. An enrichment analysis showed that AA treatment induced chromosomal changes, mitosis, and muscle differentiation, while IGF1 modulated IGF/PI3K signaling, metabolic alteration, and matrix structure. In addition, potential molecular markers were similarly modulated by both treatments. Muscle-miRNAs (miR-1, -133, -206 and -499) were up-regulated, especially in AA samples, and we identified molecular networks with omics integration. Two pairs of genes and miRNAs demonstrated a high-level relationship, and involvement in myogenesis and muscle growth: marcksb and miR-29b in AA, and mmp14b and miR-338-5p in IGF1. Our work helps to elucidate fish muscle physiology and metabolism, highlights potential molecular markers, and creates a perspective for improvements in aquaculture and in in vitro meat production

Identification of dietary patterns in urban population of Argentina: study on diet-obesity relation in population-based prevalence study

BACKGROUND/OBJECTIVES: In Argentina, obesity prevalence rose from 14.6% in 2005 to 20.8% in 2013. Although the number of studies on noncommunicable diseases and dietary patterns as a unique dietary exposure measure has increased, information on this topic remains scarce in developing countries. This is the first population-based study investigating the association between diet and obesity using a dietary pattern approach in Argentina. We aimed (a) to identify current dietary patterns of the population of Córdoba city, (b) to investigate its association with obesity prevalence, and (c) to identify and describe dietary patterns from the subgroup of people with obesity. SUBJECTS/METHODS: The Córdoba Obesity and Diet Study (CODIES) was conducted in Córdoba city by using a random sample of n = 4,327 subjects between 2005 and 2012. Empirically derived dietary patterns were identified through principal component factor analysis. A multiple logistic regression analysis was used to investigate the association of dietary patterns with obesity. RESULTS: Four dietary patterns were identified, called “Starchy-Sugar”, “Prudent”, “Western”, and “Sugary drinks”. High scores for the “Western” pattern (with strongest factor loading on meats/eggs, processed meats, and alcohol) showed a positive association with obesity (OR: 1.33, 95% CI: 1.06-1.67, for third versus first tertile of factor score). “Meats/Cheeses” and “Snacks/Alcohol” patterns emerged in people with obesity. CONCLUSIONS: The findings suggest that high adherence to the “Western” pattern promoted obesity in this urban population. In addition, people with obesity showed characteristic dietary patterns that differ from those identified in the overall population.publishedVersionFil: Pou, Sonia Alejandra.
