Multifactorial Ethiopathogenic In Eating Disorders

Eating Disorders is a heterogeneous group of syndromes which includes many factors in their develop. The three main syndromes, AN, BN and EDNOS has been defined in last DSM as independent entities. However is well known that a group of patients may change its presentation along time, so also been at first diagnosed of AN, lately will fulfil criteria for BN or EDNOS.

In the other hand, if we compare two patients with the same syndrome, as BN, or AN…

We may easily find big differences in personality, stressors…and in some cases the only common factor is the clinical presentation.

Behind all of this is the fact that syndromic classification drives to empiric treatments that are far the most validated.

But although there is a well known evolution in this disorders, with a not so bad income as one could think initially (in some cases one third could recover without treatment), what may we do with those patients that are resistant for empiric treatments?

And it is our opinion that a deeper knowledge of all the factors that contribute to the syndrome or its presentation, as well as those related to treatments results, should be taken into account.

We have reviewed all knowledge about these issues and we have completed it with our clinical practise using a 50 patients data base, here we will show our results, that are basically that even the same factors interact in different ways in each patient, so it is not just the ingredients but the recipe.

Brief psychotherapy in eating disorders

First time we began to work with eating disorders, we used to hear the chronic course of the illness and the long-term treatment that our patients would need. When you have a team trained in brief psychotherapy, but not in this specific area, it sounds as just the opposite you try to reach with your patients. National guidelines however are full of psycho-educational and cognitive-conduct treatment's models, without any other validated kind of treatment. However, it was our experience that solution focused or problem focused therapy were also two clinical effective approaches to many psychiatric problems. In fact, we had a mature consult, in which as far as two thirds of patients had become, some way chronic. Problem was, as far as we can imagine, if that was a disease's effect or a lack of a deeper intervention, which were wider than those classic. So, we classified our patients in resistant or not resistant, and doing so we add brief therapy to the first group, reevaluating every week each intervention and the course of the illness. By doing so, we found that chronicity was, in same cases, just the result of limited treatments. Here we have analysed some chronic patients with a bad course and the alternatives that let them to recover.

The American Society for Clinical Pathology's 2014 vacancy survey of medical laboratories in the United States

OBJECTIVES

To determine the extent and distribution of workforce shortages within the nation's medical laboratories. Historically, the results of this biennial survey have served as a basis for additional research on laboratory recruitment, retention, education, marketing, certification, and advocacy.

METHODS

The 2014 Vacancy Survey was conducted through collaboration between American Society for Clinical Pathology's Institute of Science, Technology, and Policy in Washington, DC, and the Evaluation, Measurement, and Assessment Department and Board of Certification in Chicago, Illinois. Data were collected via an Internet survey that was distributed to individuals who were able to report on staffing and certifications for their laboratories.

RESULTS

Data reveal increased overall vacancy rates since 2012 for all departments surveyed except cytology and cytogenetics. Also, results show higher anticipated retirement rates for both staff and supervisors. Overall certification rates are highest among laboratory personnel in cytogenetics, hematology/coagulation, and flow cytometry departments and lowest among phlebotomy, specimen processing, and anatomic pathology.

CONCLUSIONS

Factors such as retirement and the improving economy are driving the need for more laboratory professionals. Recruitment of qualified laboratory professionals in the workforce and students in laboratory programs will be the key in fulfilling the higher vacancies revealed from the survey results in 2014.

Highly Electrically Conducting Glass-Graphene Nanoplatelets Hybrid Coatings

Hybrid coatings consisting of a heat resistant Y2O3-Al2O3-SiO2 (YAS) glass containing 2.3 wt % of graphene nanoplatelets (GNPs) were developed by flame spraying homogeneous ceramic powders-GNP granules. Around 40% of the GNPs survived the high spraying temperatures and were distributed along the splat-interfaces, forming a percolated network. These YAS-GNP coatings are potentially interesting in thermal protection systems and electromagnetic interference shields for aerospace applications; therefore silicon carbide (SiC) materials at the forefront of those applications were employed as substrates. Whereas the YAS coatings are nonconductive, the YAS-GNP coatings showed in-plane electrical conductivity (∼10(2) S·m(-1)) for which a low percolation limit (below 3.6 vol %) is inferred. Indentation tests revealed the formation of a highly damaged indentation zone showing multiple shear displacements between adjacent splats probably favored by the graphene sheets location. The indentation radial cracks typically found in brittle glass coatings are not detected in the hybrid coatings that are also more compliant.

TiO2 Fibers: Tunable Polymorphic Phase Transformation and Electrochemical Properties

A series of one-dimensional (1 D) nanoparticle-assembled TiO2 fibers with tunable polymorphs were prepared via a novel and large scale ForceSpinning process of titanium tetraisopropoxide (TTIP)/polyvinylpyrrolidone (PVP) precursor fibers followed with a thermal treatment at various calcination temperatures. The thermal and structural transformations were characterized by thermogravimetric analysis/differential scanning calorimetry, scanning electron microscopy, and X-ray diffraction. The influence of polymorphic phase of the TiO2 fibers on the electrochemical performance in neutral aqueous 1 M Na2SO4 electrolyte was investigated. The polymorphic amorphous/anatase/rutile TiO2 fibers prepared at 450 degrees C achieved a highest capacitance of 21.2 F g(-1) (6.61 mF cm(-2)) at a current density of 200 mA g(-1), for which the improved electronic conductivity and activated pseudocapacitance mechanism may be responsible. This work helps bridge the gap between nanoscience and manufacturing. It also makes polymorphism control of functional materials a potential strategy for further improving supercapacitive output of metal oxides.

Feasibility and safety of biventricular repair in neonates with hypoplastic left heart complex

Hypoplastic left heart syndrome is a spectrum of structural cardiac malformations characterized by variable underdevelopment of the left heart-aorta complex. A minority of patients having a milder degree of left ventricular hypoplasia, described as hypoplastic left heart complex (HLHC), may be selected for biventricular repair. The objective of this study was to assess the outcome of the biventricular approach in HLHC. We evaluated retrospectively 30 neonates diagnosed with HLHC from the "12 de Octubre" University Hospital, following established criteria. We analyzed the echocardiographic data recorded just after birth and at last follow-up after surgery. All patients were operated on in the neonatal period using various surgical techniques. There were no early deaths and only 1 late death after a mean follow-up of 62.9 ± 43.8 months. All patients presented a significant growth of the left ventricular structures, with a Z-score increase of 1.17 ± 1.05 for mitral annulus, 1.72 ± 1.23 for aortic annulus, and 1.33 ± 1.46 for left ventricular end-diastolic diameter. Postoperatively, 18 patients showed a left valvular stenosis, and 17 patients underwent a reoperation and/or an interventional procedure. Freedom from surgery or interventional catheterizations at 1, 3 and 5 years was 53, 49 and 43%, respectively. The 29 current survivors are all in a good functional status. In our experience, we achieved good results from biventricular repair in patients with HLHC, with a significant growth of left heart structures and an excellent clinical status at a medium-term follow-up. Nevertheless, there was a high rate of reoperations and/or interventional catheterizations.

Risk factors associated with preterm delivery after fetoscopic laser ablation for twin-twin transfusion syndrome

OBJECTIVE

Despite improved perinatal survival following fetoscopic laser ablation (FLA) for twin-twin transfusion syndrome (TTTS), prematurity remains an important contributor to perinatal mortality and morbidity. The objective of the study was to identify risk factors for complicated preterm delivery after FLA.

METHODS

Retrospective cohort study of prospectively collected data on maternal/fetal demographics and pre-operative, operative and postoperative variables of 459 patients treated with FLA in three USA fetal centers. Multivariate linear regression was performed to identify significant risk factors associated with preterm delivery, which were cross-validated using the k-fold method. Multivariate logistic regression was performed to identify risk factors for early compared with late preterm delivery based on median gestational age at delivery of 32 weeks.

RESULTS

There were significant differences in case selection and outcomes between the centers. After controlling for the center of surgery, multivariate analysis indicated that a lower maternal age at procedure, a history of previous prematurity, shortened cervical length, use of amnioinfusion, a cannula diameter of 12 French (Fr), lack of a collagen plug placement and iatrogenic preterm premature rupture of membranes (iPPROM) were significantly associated with a lower gestational age at delivery.

CONCLUSIONS

Specific fetal/maternal and operative variables are associated with preterm delivery after FLA for the treatment of TTTS. Further studies to modify some of these variables may decrease the perinatal morbidity after laser therapy.

Identifying sickle cell disease cases using administrative claims

OBJECTIVE

To develop and test the accuracy of administrative claims method for identifying children with sickle cell disease (SCD) to enable quality of care assessments among children enrolled in Medicaid.

METHODS

All administrative claims with an SCD diagnosis were obtained from Michigan Medicaid from 2008 to 2011 for children ≤18 years, representing 1828 individuals. All Medicaid claims were obtained for these children and classified into categories on the basis of SCD care; these classifications were used to develop 37 alternative case definitions for identifying children with SCD. Children with ≥1 SCD claim in 2010 or 2011 were identified as confirmed SCD or not SCD using the gold standard of Michigan newborn screening administrative records. Measures of performance were calculated for each case definition for eligible children in 2010. Further validation of the case definitions was performed among eligible children in 2011.

RESULTS

In 2010, a total of 938 children met eligibility criteria and were linked to newborn screening records; 605 (59%) were confirmed SCD, and 333 (32%) were not SCD. Measures of performance varied among the 37 case definitions, and the 4 best case definitions on the basis of the sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve were validated among 924 children meeting eligibility criteria in 2011. The case definition of at least 3 SCD claims in any position identified children with SCD with the most accuracy, with an area under the ROC curve of 0.91 (95% confidence interval 0.89, 0.93).

CONCLUSIONS

This definition can be used to facilitate a more accurate identification of children with SCD in future studies. Further investigation is necessary to determine whether this method translates to other populations besides Michigan Medicaid-insured children.
