If It Looks Like a Duck and Quacks Like a Duck: Evaluating the Validity of Borderline Personality Disorder in Adolescents
Authors: Sharp Carla , Kalpakci Allison 
Published: July 2016

Abstract

Background:
The validity of borderline personality disorder (BPD) has been a topic of much controversy in psychiatry. Over the last two decades, a wealth of empirical work has challenged long-held concerns regarding the validity of adolescent BPD. However, this research has been conducted within a traditional approach to psychiatric nosology.

Objective:
In this article, we aim to evaluate the validity of adolescent BPD as guided by both the Robins and Guze criteria for the validity of psychiatric constructs and the new National Institute of Mental Health Research Domain Criteria (NIMH RDoC).

Method:
We used the five principles of the Robins and Guze approach to evaluate selected research from our own and other groups regarding the validity of adolescent BPD. These principles include clinical description studies, laboratory studies, studies that delimitate the disorder from other related syndromes, follow-up studies, and family studies.

Results:
Within the Robins and Guze criteria framework, evidence to date supports the validity of adolescent BPD to some extent. However, limitations of the research about the construct validity of adolescent BPD have also been identified, most notably regarding the delimitation of adolescent BPD from other disorders as well as a lack of longitudinal and family studies.

Conclusions:
Given these limitations and the limitations of the Robins and Guze approach to psychiatric nosology, we recommend exploring the potential of the National Institute of Mental Health Research Domain Criteria as a complement to previous work.
African Anti-Colonialism and the <em>Ultramarinos</em> of the <em>Casa dos Estudantes do Império</em>
Authors: Reza Alexandra 
Published: July 2016

In this article, I examine the "space between" occupied by students at the Casa dos Estudantes do Império, a crucial nexus for independence campaigns in Lusophone Africa. Drawing on readings of the Casa’s journal, Mensagem, I argue that the students saw political affiliation as a constant movement between formulations of "home" and "the world." I situate this dilaectical approach in the context of Portuguese fascism, paying particular attention to the political poetry published in Mensagem, and analyzing the ways in which members of the Casa imagined their relationship to other African anti-colonial movements.
Noise reduction in centrifugal pump as turbine: influence of leaning blade or tongue
Authors: Dai Cui , Dong Liang , Xia Bin , Kong Fan Yu 
Published: June 2016

To reduce the interior/exterior flow-induced noise in centrifugal pump as turbine (PAT), based on the relation between in-phase hydrodynamic action and radiated noise, the angle formula in ideal condition by individually leaning blade was proposed. Considering the joint leaning effect, the formulas associated with parallel- and counter-leaning blade and tongue were presented. The corresponding active noise reduction approaches were put forward without losing hydraulic performance. For noise simulation, the numerical method for interior noise and finite element model for casing structure were checked, with good agreements achieved. The boundary element method (BEM) and finite element method (FEM) were used to investigate the interior/exterior noise characteristics of PATs by varying the shapes of blade or tongue. Researches show that the interior noise due to casing source can reflect joint action of multiple sources. It is feasible to predict the interior noise induced only by casing source through BEM. The leaned blade can keep PAT’s original performance, the leaned tongue can significantly improve the efficiency overall operating range with an increase from 0.67 % to 1.81 %, and the combined counter-leaning blade and tongue can increase the efficiency in larger flow rates. They can all reduce sound pressure level (SPL) at fundamental frequency and total sound energy, and the noise reduction effect under joint action is best.
Study of measured indoor low-frequency noise levels resulting from outdoor noise sources, using a simplified physical model as well as empirical and FEM calculations
Authors: Saliunas Darius , Volkovas Vitalijus , Janusevicius Tomas 
Published: June 2016

The paper presents an investigation simulating transformations of an acoustic field at low frequencies indoors, when the sound source is outdoors. The investigation was performed using a simplified and 5-times-smaller physical model. The paper presents measured spatial sound pressure level (SPL) distribution at 1/3 octave bands as well as at discrete frequencies (at various room modes). Measurements inside the physical model (at a total of 2,565 points) confirm that when exposed to outdoor broadband noise, low-frequency sound pressure levels at 1/3 octave bands inside the room can differ by more than 30 dB, while at discrete frequencies measured SPL can vary by 50 dB or more. Below the calculated lowest room mode, due to resonant vibrations of physical model walls, large differences in sound pressure levels inside the model (up to 20.7 dB at 100 Hz 1/3 octave band and up to 32.4 dB at discrete Hz frequencies) were found. The investigation also includes analysis of levels in the corners of physical models compared to average sound pressure levels in the whole model space or some cross-sections, which shows that sound pressure levels in corners can be up to 10 dB lower. Calculation of the indoor average sound pressure level at low frequencies according to empirical formulas specified in standard ISO 12354-3 showed conformity between measurement and calculation results only in a part of the investigated range of frequency bands. Calculations using FEM at discrete frequencies gave more adequate results of sound pressure levels and their spatial distribution. FEM calculations proved that calculation of the average sound pressure level from measurements at points every 25 cm (every 5 cm in the physical model) can produce results close to the average of the sound pressure level of the room if it were measured at every possible position.

Authors: Barreto Hernández Alix , Velasco Luz Adriana 
Published: July 2016

Con el fin de crear una colección de microalgas bentónicas marinas del Caribe colombiano, algunas cepas fueron aisladas y cultivadas bajo diferentes condiciones de temperatura. A partir de muestras de perifiton de placas de PVC colocadas en el intermareal rocoso de Taganga, Santa Marta (Colombia), se evaluó el tipo y número de microalgas aisladas, así como la densidad y la constante de crecimiento relativo (K) de tres de las cepas aisladas bajo tres temperaturas de cultivo (20, 25 y 28 °C). Se mantuvieron condiciones constantes de medio de cultivo F/2 de Guillard, iluminación artificial (1500 lux) y valores iniciales de salinidad de 30‰ y pH de 7,0. Se logró el aislamiento de cinco cepas de microalgas a una temperatura de 20 °C (Cylindrotheca closterium, Komvophoron crassum, Tetraselmis sp. y 2 morfotipos de la familia Bacillariaceae); a 25 y 28 °C ninguna cepa fue obtenida. En la diatomea identificada como Bacillariaceae morfotipo 1, los valores mayores de densidad celular (96,3 x 105 cel.ml-1) y K (1,03 div. día-1), se obtuvieron a temperaturas de 20 y 25 °C, mientras que a 28 °C fue imposible obtener su crecimiento. Contrariamente, en las microalgas Cylindrotheca closterium y Tetraselmis sp., los valores mayores de densidad (2,6 y 7,7 x 105 cel.ml-1, respectivamente) se obtuvieron en el tratamiento de 25 °C, mientras que los mayores valores de K ocurrieron a 28 °C (0,64 y 0,60 div. d-1, respectivamente). Este estudio permitió iniciar un cepario de microalgas bentónicas del Caribe colombiano, así como determinar las temperaturas más apropiadas para el aislamiento microalgal (20 °C) y para la producción de células de Bacillariaceae morfotipo 1, Cylindrotheca closterium y Tetraselmis sp. (25 °C).

Los análisis espaciales han impulsado el desarrollo de modelos que permiten predecir la distribución espacial de las especies. Con estas técnicas se estima la distribución geográfica potencial, con la representación de áreas de ocurrencia de las especies, a partir de la asociación entre los registros de presencia y las variables ambientales del sitio. El objetivo de este estudio fue evaluar la eficiencia de dos modelos, el GARP y el MaxEnt, para predecir la distribución potencial de las principales especies de Lutzomyia, en un área endémica de leishmaniasis en Venezuela. Se utilizaron 190 puntos georreferenciados en el Estado Mérida Venezuela con presencia de flebotominos. Estos puntos se dividen en 67 puntos con presencia de Lutzomyia youngi, 51 de Lutzomyia gomezi, 40 de Lutzomyia ovallesi y 32 de Lutzomyia walkeri. Las variables bioclimáticas fueron tomadas de la base de datos del Worldclim para la zona 23. Los resultados muestran que ambos modelos presentaron un buen desempeño y sus rangos de distribución son consistentes entre sí. Aunque el GARP predice una mayor distribución potencial para Lutzomyia youngi y Lutzomyia gomezi, el MaxEnt genera predicciones más ajustadas de probabilidades de ocurrencia, determinadas por las variables bioclimáticas que caracterizan la distribución potencial de cada especie. Se recomienda en mayor grado el uso del MaxEnt, porque presenta una proyección de la distribución más acorde a la contribución de las variables bioclimáticas ya que aporta datos importantes para entender la dinámica de distribución de las especies de Lutzomyia y el riesgo de transmisión de leishmaniasis en el estado Mérida, Venezuela, información relevante para los entes de control.

El fitoplancton es uno de los principales productores primarios en los sistemas acuáticos; sin embargo, en los ríos, gran parte de la comunidad de microalgas se encuentran adheridas a las rocas, lo que ayuda a conformar el perifiton. Con el fin de conocer la composición de microalgas epilíticas en el río Gaira (Sierra Nevada de Santa Marta), se establecieron dos estaciones de estudio (tramo alto y tramo medio), en cada estación se realizó un raspado de un área de 6 cm2 en 10 rocas de tamaño similar (20 cm de diámetro aproximadamente). Se determinaron 55 morfoespecies, de las cuales 49 pertenecian a la clase Bacillariophyceae, tres a Chlorophyceae y dos a Cyanophyceae. Los géneros registrados son típicos de sistemas con buen estado ecológico de las aguas.

Published: June 2016

ABSTRACT: This work aimed to study the influence of metals on the temporal dynamics of cyanobacteria community in Carpina Dam (7° 53′ 22′' S and 35° 20′ 34′' W). Samples were collected from Raw Water Pumping Station at the Water Treatment Station Feira Nova in the city of Feira Nova (Pernambuco, Brazil), from January 2011 to December 2013. The concentration of metals in water (aluminum, antimony, barium, lead, copper, chromium, cadmium, iron, manganese) was determined by atomic absorption spectroscopy in the laboratory. For the identification and counting of cyanobacteria, an inverted optical microscope and Sedgewick‐Rafter counting chambers were used. Principal Component Analysis (PCA) was used for recognition of cluster patterns between the studied points. There were variations in abiotic and biotic components in the different years of study. The metals iron, aluminum, barium and manganese had the greatest influence on the temporal dynamics of cyanobacteria in the reservoir.

Published: July 2016

Background
There is a growing body of evidence relating to how information and communication technology (ICT) can be used to support people with physical health conditions. Less is known regarding mental health, and in particular, mood disorder.

Objective
To conduct a metasynthesis of all qualitative studies exploring the use of ICTs by people with mood disorder.

Methods
Searches were run in eight electronic databases using a systematic search strategy. Qualitative and mixed-method studies published in English between 2007 and 2014 were included. Thematic synthesis was used to interpret and synthesis the results of the included studies.

Results
Thirty-four studies were included in the synthesis. The methodological design of the studies was qualitative or mixed-methods. A global assessment of study quality identified 22 studies as strong and 12 weak with most having a typology of findings either at topical or thematic survey levels of data transformation. A typology of ICT use by people with mood disorder was created as a result of synthesis.

Conclusions
The systematic review and metasynthesis clearly identified a gap in the research literature as no studies were identified, which specifically researched how people with mood disorder use mobile ICT. Further qualitative research is recommended to understand the meaning this type of technology holds for people. Such research might provide valuable information on how people use mobile technology in their lives in general and also, more specifically, how they are being used to help with their mood disorders.
Clinical Prediction Rules That Don't Hold Up—Where to Go From Here?
Authors: Stanton Tasha R. 
Published: July 2016

Clinical prediction rules (CPRs) are created to help guide clinical decision making. To do this, they use the presence or absence of certain factors that have been shown to meaningfully predict a patient's prognosis, diagnosis, or response to treatment. While representing a seminal methodological step forward in individualized care, one of the main drawbacks of CPRs continues to be validation studies that do not support the initially derived CPR. This is particularly important because validation of CPRs in an independent patient population prior to clinical implementation is essential. Why is it quite common for existing CPRs to fall down at the validation stage? And what does this mean for research that aims to individualize treatment?

Published: June 2016

AbstractThis paper investigates the influence of rotational and travel speed on the structure and mechanical properties of different regions of friction stir welded dissimilar AA5251–AA5083 joints. It was observed that increasing rotational speed from 800 to 1 250 rpm, at a fixed travel speed, increased the grain size from 6.31 μm to 10.64 μm. This stemmed from higher heat input which is generated at higher rotational speed. Furthermore, it was discovered that at 1 000 rpm, 115 mm min−1 and also 1 250 rpm, 85 mm min−1, defect-free welds were produced. The results of tensile testing revealed that the best consistent tensile strength was produced at 1 000 rpm rotational speed and 115 mm min−1 travel speed with an average value of about 200 MPa. Further, the results clearly showed that the hardness values gradually increase from the 5251 aluminum side to the 5083 aluminum side.
Biplanar x-ray fluoroscopy for sacroiliac joint fusion
Authors: Vanaclocha-Vanaclocha Vicente , Verdú-López Francisco , Sáiz-Sapena Nieves , Herrera Juan Manuel , Rivera-Paz Marlon 
Published: July 2016

Chronic pain originating from the sacroiliac joint (SI) can cause severe dysfunction. Although many patients respond to conservative management with NSAIDs, some do need further treatment in the form of SI joint fusion (SIJF). To achieve safe and successful SIJF, intraoperative x-ray fluoroscopy is mandatory to avoid serious damages to nearby vascular and neural structures. Each step of the procedure has to be confirmed by anteroposterior (AP) and lateral projections. With a single-arm x-ray, the arch has to be moved back and forth for the AP and lateral projections, and this lengthens the procedure. To achieve the same results in less time, the authors introduced simultaneous biplanar fluoroscopy with 2 x-ray arches. After the patient is positioned prone with the legs spread apart in the so-called Da Vinci position, one x-ray arch for the lateral projection is placed at a right angle to the patient, and a second x-ray machine is placed with its arch between the legs of the patient. This allows simultaneous AP and lateral x-ray projections and, in the authors' hands, markedly speeds up the procedure. Biplanar fluoroscopy allows excellent AP and lateral projections to be made quickly at any time during the surgical procedure. This is particularly useful in cases of bilateral SI joint fusion if both sides are done at the same time.The video can be found here: https://youtu.be/TX5gz8c765M.
Nonrandom spatial clustering of spontaneous anterior fossa cerebrospinal fluid fistulas and predilection for the posterior cribriform plate
Authors: Murray Richard D. , Friedlander Rachel , Hanz Samuel , Singh Harminder , Anand Vijay K. , Schwartz Theodore H. 
Published: July 2016

OBJECTIVEThe anterior skull base is a common site for the spontaneous development of meningoceles, encephaloceles, and meningoencephaloceles that can lead to cerebrospinal fluid (CSF) fistula formation, particularly in association with idiopathic intracranial hypertension. In some circumstances the lesions are difficult to localize. Whether all sites in the anterior skull base are equally prone to fistula formation or whether they are distributed randomly throughout the anterior skull base is unknown, although the anterior cribriform plate has been proposed as the most frequent location. The purpose of this study was to identify sites of predilection in order to provide assistance for clinicians in finding occult leaks and increase the understanding of the etiology of this pathology.METHODSThe authors performed a retrospective review of a prospectively acquired surgical database of all endonasal endoscopic surgeries performed at Weill Cornell Medical College by the senior authors. Spontaneous CSF fistulas of the anterior skull base were identified. The anatomical sites of the defects were located on radiographic images and normalized to a theoretical 4 × 2 grid representing the anterior midline skull base. Data from the left and right skull base were combined to increase statistical power. This grid was then used to analyze the distribution of defects. Frequency analysis was performed by means of a chi-square test, with a subsequent Monte Carlo simulation to further strengthen the statistical support of the conclusions.RESULTSNineteen cases of spontaneous CSF fistulas were identified. Frequency analysis using chi-square indicated a nonrandom distribution of sites (p = 0.035). Monte Carlo simulation supported this conclusion (p = 0.034). Seventy-four percent of cases occurred in the cribriform plate (p = 0.086). Moreover, 37% of all defects occurred in the posterior third of the cribriform plate.CONCLUSIONSAnterior skull base spontaneous CSF leaks are distributed in a nonrandom fashion. The most likely site of origin of the spontaneous CSF leaks of the anterior midline skull base is the cribriform plate, particularly the posterior third of the plate, likely because of the lack of significant thick bony buttressing. Clinicians searching for occult spontaneous leaks of the anterior skull base should examine the cribriform plate, especially the posterior third with particularly close scrutiny.

OBJECTIVEThe purpose of the present study was to investigate the epigenetic and prognostic roles of an H3K4 methyltransferase (mixed lineage leukemia 4 [MLL4]) and H3K27 demethylase (ubiquitously transcribed tetratricopeptide repeat gene on X chromosome [UTX]) in progression-free survival (PFS) and overall survival (OS) of patients with glioblastoma (GBM) who were treated with radiotherapy, chemotherapy, or both after resection. In addition, the authors examined methylation at the promoter of the O-6-methylguanine-DNA methyltransferase (MGMT) gene and other prognostic factors predicting length of PFS and OS in these patients.METHODSThe medical records of 76 patients having a new diagnosis of histologically ascertained GBM in the period of January 2002 to December 2013 at the authors' institution were retrospectively reviewed. Immunohistochemical staining for MLL4 and UTX was performed on archived paraffin-embedded tissues obtained by biopsy or resection. The methylation status of the MGMT promoter in these tissues was determined by methylation-specific PCR analysis.RESULTSDuring the follow-up period (mean length 18.1 months, range 4.1–43.5 months), 68 (89.5%) of the patients died. The MGMT promoter was methylated in 49 patients (64.5%) and unmethylated in 27 (35.5%). The immunoreactivity pattern of UTX was identical to that of MLL4; increased expression of these 2 proteins was observed in samples from 34 patients (44.7%) and decreased expression in 42 patients (55.3%). The mean length of PFS was 9.2 months (95% CI 6.8–11.6 months). Extent of surgery, recursive partitioning analysis (RPA) class, and methylation status of the MGMT promoter were all associated with increased PFS in the multivariate analysis of factors predicting PFS. The mean length of OS was 18.6 months (95% CI 14.3–22.9 months). Patient age (p = 0.004), WHO performance status score (p = 0.019), extent of surgery (p = 0.007), RPA class (p = 0.036), methylation status of the MGMT promoter (p = 0.010), and increased expression of UTX-MLL4 (p = 0.001) were significantly associated with increased OS in multivariate analysis. Interestingly, in patients with an unmethylated MGMT promoter, immunoreactivity of UTX-MLL4 was not associated with changes in OS (p = 0.350). However, in the patients with a methylated MGMT promoter, increased UTX-MLL4 expression was strongly associated with increased OS (p < 0.001).CONCLUSIONSThe results of this study suggest that increased expression of UTX-MLL4 positively influences the outcome of patients with GBM having a methylated MGMT promoter. Therefore, UTX-MLL4 immunoreactivity could be a useful predictor of the response to conventional treatment with radiotherapy or chemotherapy among GBM patients whose tumors have a methylated MGMT promoter.
