Estudio evaluativo-comparativo acerca de una intervención grupal a madres con hijos prematuros del Hospital San josé, en relación al vínculo temprano materno-infantil, desde la teoría del apego.

Tesis (Licenciado en Psicología)La presente investigación tuvo por finalidad diseñar e implementar una intervención dirigida a madres de recién nacidos prematuros. El objetivo de la investigación es la contribución a través de la intervención del fortalecimiento del vínculo de la pareja madre-bebé. La población se constituyó con madres -entre 16 y 35 años-que durante el segundo semestre del 2003 dieron a luz a sus hijos de manera prematura. Para fines de nuestra investigación se escogió una muestra de diez madres del Hospital San José, las que en primera instancia atravesaron por un proceso de evaluación que constó de la aplicación de instrumentos de diversa índole entrevista de despistaje (PERI), entrevista de fantasías, Pauta de apego en adultos (P.8.1. Posteriormente, se dividió la muestra en un grupo control y uno experimental. Este último fue escogido para participar en el taller diseñado por las investigadoras, cuyo objetivo principal consistió en entregarles herramientas a las madres para que pudiesen establecer un apego más seguro y confiable con sus hijos, impartiendo contenidos -madre suficientemente buena, bebé imaginario y real, mentalización, sintonía afectiva, reverie, etc. y generando un ambiente de contención donde tuviesen la oportunidad de desplegar sus ansiedades y temores. La metodología empleada para evaluar a ambos grupos una vez terminada la intervención, consistió en la observación de las díadas en su ambiente natural. Dicho procedimiento se llevó a cabo una vez a la semana durante un mes, con una duración de una hora por visita -de acuerdo al modelo propuesto por la clínica Tavistock, Londres-. Posteriormente, se sistematizó lo observado en una pauta de perfil de la observación del vínculo madre-bebé. Esta pauta fue utilizada para poder comparar a ambos grupos después de haber realizado la intervención. Los resultados confirman la efectividad de la realización de una intervención temprana en díadas, generando aportes en el establecimiento de un apego más seguro en la pareja madre-bebé.The objective of this study is to design and implement an intervention aimed at mothers with prematura new-bom babies. Moreover, this intervention will contribute to strengthen the link between the mother and her child. The group studied was constituted by mothers between the ages of 16 and 35 years, who had given birth to a prematura child during the last six months of the year 2003. For the purposes of this study, a test-group of ten mothers from the Hospital San José was chosen. These mothers underwent, in the first instance, a period of evaluation where diverse tools were applied, such as interviews to make sure that there were no pathologies associated (PERI), fantasy interviews and a Parental Bonding lnstrument (PBI). The samples were then divided into two groups, a control group and an experimental group. This latter group was chosen to participate in the workshop designad by the research team. The main objective of this workshop was to provide the mothers with tools to furthen strengthen their relation with the new-bom child. This could be done using the following tools: explaining to the mothers the concepts of sufficiently good mother, imaginad baby and real baby, mentalization, affective syntony, reverie, etc., as well as by generating an atmosphere of contension where the mothers could express their anxieties and fears. The methodology used to evaluate both groups once finalised the intervention was to observe the interaction between mothers and their newbom babies in their natural environment. Such a procedure took place once a week during one month. The duration of the visit was of one hour, using the time-frame proposed by the Tavistock Clinic in London. Further to this, the observations were recordad in a profile guideline of the mother-baby link. These guidelines were used to analyse and compare both groups after the intervention had taken place. The results confirm the effectiveness of carrying out this intervention at an early stage with mothers and their newbom babies in order to contribute to the strengthening and securing of mother-child ties

Effect of viral storm in patients admitted to intensive care units with severe COVID-19 in Spain: a multicentre, prospective, cohort study

Background: The contribution of the virus to the pathogenesis of severe COVID-19 is still unclear. We aimed to evaluate associations between viral RNA load in plasma and host response, complications, and deaths in critically ill patients with COVID-19. Methods: We did a prospective cohort study across 23 hospitals in Spain. We included patients aged 18 years or older with laboratory-confirmed SARS-CoV-2 infection who were admitted to an intensive care unit between March 16, 2020, and Feb 27, 2021. RNA of the SARS-CoV-2 nucleocapsid region 1 (N1) was quantified in plasma samples collected from patients in the first 48 h following admission, using digital PCR. Patients were grouped on the basis of N1 quantity: VIR-N1-Zero ([removed]2747 N1 copies per mL). The primary outcome was all-cause death within 90 days after admission. We evaluated odds ratios (ORs) for the primary outcome between groups using a logistic regression analysis. Findings: 1068 patients met the inclusion criteria, of whom 117 had insufficient plasma samples and 115 had key information missing. 836 patients were included in the analysis, of whom 403 (48%) were in the VIR-N1-Low group, 283 (34%) were in the VIR-N1-Storm group, and 150 (18%) were in the VIR-N1-Zero group. Overall, patients in the VIR-N1-Storm group had the most severe disease: 266 (94%) of 283 patients received invasive mechanical ventilation (IMV), 116 (41%) developed acute kidney injury, 180 (65%) had secondary infections, and 148 (52%) died within 90 days. Patients in the VIR-N1-Zero group had the least severe disease: 81 (54%) of 150 received IMV, 34 (23%) developed acute kidney injury, 47 (32%) had secondary infections, and 26 (17%) died within 90 days (OR for death 0·30, 95% CI 0·16–0·55; p<0·0001, compared with the VIR-N1-Storm group). 106 (26%) of 403 patients in the VIR-N1-Low group died within 90 days (OR for death 0·39, 95% CI 0·26–0·57; p[removed]11 página

The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients

Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV
