Ignacio Sanz-Martín,Jae-Kook Cha,윤성욱,Ignacio Sanz-Sánchez,정의웅 대한치주과학회 2019 Journal of Periodontal & Implant Science Vol.49 No.2

The primary aim of this systematic review was to assess the evidence on periodontal disease progression after treatment in patients receiving supportive periodontal therapy (SPT) and to identify predictors of clinical attachment level (CAL) loss. A protocol was developed to answer the following focused question: In adult patients treated for periodontitis, what is the disease progression in terms of CAL loss after surgical or non-surgical treatment? Randomized controlled clinical trials, prospective cohort studies, and longitudinal observational human studies with a minimum of 5 years of follow-up after surgical or non-surgical treatment that reported CAL and probing depth changes were selected. Seventeen publications reporting data from 14 investigations were included. Data from 964 patients with a follow-up range of 5–15 years was evaluated. When the CAL at the latest follow-up was compared to the CAL after active periodontal therapy, 10 of the included studies reported an overall mean CAL loss of ≤0.5 mm, 3 studies reported a mean CAL loss of 0.5–1 mm, and 4 studies reported a mean CAL loss of >1 mm. Based on 7 publications, the percentage of sites showing a CAL loss of ≥2 mm varied from 3% to 20%, and a high percentage of sites with CAL loss was associated with poor oral hygiene, smoking, and poor compliance with SPT. The outcomes after periodontal therapy remained stable over time. Disease progression occurred in a reduced number of sites and patients, mostly associated with poor oral hygiene, poor compliance with SPT, and smoking.

Study Design: Case-control study. Purpose: Analyze association between imaging factors related to the failure of conservative treatment in isolated subaxial cervical facet fractures. Overview of Literature: Facet fracture (F1, F2, and F3 AOSpine) may be stable or unstable depending on clinical and imaging variables, which are not well established. As a result, differences in fracture management lead to differences in surgical or conservative indications, and there is no evidence to predict conservative treatment failure. Methods: Patients were categorized into two groups: six patients (16.2%) with conservative treatment failure (defined as the appearance of neurological symptoms, listhesis >3.5 mm, kyphotic deformation >11°, and/or non-union), and 31 patients (83.7%) with successful conservative management (defined as complete consolidation confirmed by computed tomography [CT] at the 6-month follow-up). All participants were fitted with rigid collars of the Miami type, and standardized follow-up was performed until consolidation or failure. CT and magnetic resonance imaging (MRI) was used to examine imaging characteristics. Sagittal balance parameters were assessed using CT, and signs of acute disc injury, prevertebral edema, facet synovitis, and interspinous hyperintense signal were assessed using MRI. Results: Thirty-seven patients were diagnosed with unilateral cervical facet fractures between 2009 and 2020. In this sample, acute disc injury had a significative association to failure of conservative treatment in F2 and F3 AOSpine facet fractures, 100% of the failure group presented with traumatic disc injury compared to 9.7% of the successful group, for the other variables: prevertebral edema, 83.7% vs. 41.9%; facet synovitis, 100% vs. 77.4%; and interspinous hyperintensity, 71.4% vs. 38.7%, respectively. With conservative management, all F1 fractures healed successfully. Conservative treatment failed in 20% of F2 fractures and 50% of F3 fractures, respectively. In terms of cervical sagittal balance parameters, there were no significant differences between groups. Conclusions: Conservative management was successful in all F1 fractures. In F2 and F3 types, there was a significant association between acute disc injury and conservative treatment failure.

"Do they see me as a Professional?”: Narratives of an Early Childhood Teacher in the Context of COVID-19 Pandemic

Figueroa-Céspedes Ignacio(Figueroa-Céspedes Ignacio),Guerra Paula(Guerra Paula) The Pacific Early Childhood Education Research Ass 2024 Asia-Pacific journal of research in early childhoo Vol.18 No.1

This article analyses the experience of a Chilean early childhood (EC) teacher in the context of the COVID-19 pandemic. Part of a broader qualitative and narrative research, this article is a case study based on her professional experience during the pandemic. The results reveal four phases in the process: (1) initial confusion, (2) proposal, (3) disappointment and action, (4) balance and dialogue. The narrative shows a series of situations experienced by the EC teacher in her relationship with the children’s families, where identity negotiation emerged linked to the revalidation of her professional role. In addition, developing teaching and collaborative skills to respond to emergency situations is highlighted. Based on this experience, the need to elicit cultural changes that articulate care and pedagogical fields in EC education in Chile is analysed.

Pulmonary Embolism from Cement Augmentation of the Vertebral Body

Jose Manuel Fernando Ignacio,Katrina Hannah Dizon Ignacio 대한척추외과학회 2018 Asian Spine Journal Vol.12 No.2

Pulmonary cement embolism (PCE) can follow cement augmentation procedures for spine fractures due to osteoporosis, traumatic injuries, and painful metastatic lesions. PCE is underreported and it is likely that many cases remain undiagnosed. Risk factors for PCE have been identified, which can help alert clinicians to patients likely to develop the condition, and there are recommended techniques to reduce its incidence. Most patients with PCE are asymptomatic or only develop transient symptoms, although a few may exhibit florid cardiorespiratory manifestations which can ultimately be fatal. Diagnosis is mainly by radiographic means, commonly using simple radiographs and computed tomography scans of the chest with ancillary tests that assess the patient’s cardiorespiratory condition. Management depends on the location and size of the emboli as well as the patient’s symptomatology. The aim of this review is to raise awareness of the not uncommon complications of PCE following vertebral cement augmentation and the possibility of serious sequelae. Recommendations for the diagnosis and management of PCE are presented, based on the most recent literature.

Autonomous Constitutional Bodies as new limits to Mexican presidentialism — A constitutional and political debate —

Ignacio Garcia Marin,Ana Cristina González Rincon 세계헌법학회한국학회 2021 世界憲法硏究 Vol.27 No.1

This research discusses the role that Autonomous Constitutional Bodies (OCAs in Spanish) play within presidentialism in the Mexican political system. We start briefly from the evolution of the liberal state, the classic triad on the separation and division of powers and its recent evolution in Mexico until the transition to democracy in 2000. Later, it will be analyzed from a constitutional and political view, one of the main Mexican constitutional innovations that paved this path with the creation of the OCAs, which facilitated the loss of constitutional powers of the head of State and the end of imperial presidentialism. To facilitate understanding the OCAs and their legal configuration, it will be focused on the Mexican ombudsperson, which is called the National Human Rights Commission (CNDH in Spanish), which well exemplifies the limits of these institutions but also their capacity to modernize and democratize the Mexican State.

La antiguedad clasica como fuente y contexto en El esclavo en grillos de oro de Bances Candamo

( Ignacio Lopez Calvo ) 한국스페인어문학회 2006 스페인어문학 Vol.0 No.41

La antiguedad clasica sirve de trasfondo a la comedia El esclavo en grillos de oro en donde el dramaturgo aurisecular Francisco Bances Candamo(1662-1704)refleja sus inquietudes politicas. Con la presentacion de los enredos politicos del imperio romano, el dramaturgo asturiano consigue que el lector-espectador tome conciencia de la sombra amenazadora que acosa a la monarquia de Carlos II el Hechizado (1661-1700), dada la ausencia de heredero. La critica ha mencionado varios tratados destinados a la educacion de principes. Sin embargo, no se ha mencionado nunca un texto que parece haber tenido tambien mucha influencia en su obra: la Oracion a Nicocles, rey de Chipre, de Isocrates. En El esclavo en grillos de oro, ademas del esperado panegirico al rey, encontramos una osadia que acabaria costando muy cara a su autor. Como Isocrates, Bances Candamo tratade educar al rey para el buen gobierno e incluso se atreve a volver a mencionar el tema tabu de la sucesion. Al instar indirectamente al rey a que buscara un heredero para Espana, y al criticar a los allegados al emperador romano, la corte lo considero una afrenta tanto al rey como al privado de Carlos II. De hecho, tras ser herido en el pecho por un espectador que vio en El esclavo en grillos de oro un ataque al Conde de Oropesa, privado del rey, Bances Candamo se vio obligado, como se menciono anteriormente, a dejar su cargo y huir de Madrid por un tiempo.

Scaling Echocardiographic Cardiac Dimensions to Body Size: A Bayesian Analysis in Healthy Men and Women

Ignacio Iglesias-Garriz,David Alonso,Carmen Garrote,Victoria Casares,Javier Vara,Jose Maria De la Torre,Miguel A. Rodriguez,Felipe Fernandez-Vazquez 한국심초음파학회 2020 Journal of Cardiovascular Imaging (J Cardiovasc Im Vol.28 No.1

BACKGROUND: Proper scaling of cardiac dimensions is of paramount importance in making correct decisions in clinical cardiology. The usual normalization of cardiac dimensions to overall body size assumes an isometric relationship. We sought to investigate these relationships to obtain the best allometric coefficient (AC) for scaling. METHODS: Ninety-seven healthy volunteers were included. The dimensions to be scaled were the left atrial volume, the end-diastolic and end-systolic left ventricular volumes, and the diameter of the tricuspid annulus. A Bayesian statistical analysis was applied with isometric coefficients as priors. RESULTS: The linear correlations between cardiac dimensions and body size were modest, ranging from 0.12 (-0.10–0.32) for the left atrial volume and height to 0.70 (0.58–0.80) for the end-diastolic volume and height. The ACs varied across the different cardiac dimensions and body size measurements. For the best linear relationships, the isometric coefficients were outside the 95% highest density interval of the posterior distribution for the left atrial volume-weight (AC: 0.7; 0.4–0.9) and end-diastolic volume-height (AC: 2.3; 1.7–2.9), whereas they were different from 1 for the left atrial volume-weight, end-diastolic volume, and diameter of the tricuspid annulus-body surface area (AC: 0.6; 0.3–0.8). Not scaling the cardiac dimensions to their corresponding ACs can lead to important errors in size estimations of cardiac structure. CONCLUSIONS: The ACs found in this study are somewhat different from the corresponding isometric coefficients and often different from 1. This finding should be considered when normalizing cardiac structures to body size when making clinical decisions.
