Group climate, cohesion and curative climate. A study on the common factors in group process and their relation with members attachment dimensions
Authors: Gullo Salvatore , Lo Coco Gianluca , Di Fratello Carla , Giannone Francesca , Mannino Giuseppe , Burlingame Gary 
Published: December 2015

This study examined the relationships among group process measured by the Group Climate Questionnaire, the Cohesion to the Therapist Scale and Cohesion to the Group Scale, and the Curative Climate Instrument to explore higher order factors that explained the group relationship, in a sample of 91 female university students attending 6 interpersonal growth groups. Furthermore, the study examined how group memberâ€™s attachment dimensions, anxiety and avoidance, were associated to his/her perception of group relationship. We found that a three-factor model consisting ofÂ positive bond, positive work, and negative relationship, approached conventional standards of model fit. Moreover, the results of the study also supported a model with three latent second-order constructs (bond, work, and negative relationship) and two structural perspectives as first-order factors (member-group and member-leader). Contrary to the hypothesis, the theoretical model on the associations between individualâ€™s attachment dimensions and group process did not fit well to the data. The results of the current study further supported the cross-cultural validation of a model with both quality and structure dimensions of group relationship. Implications for group process research are discussed.

ABSTRACTThis study reports on a case that forces re-examination of merits and demerits of anterior cervical fusion. A 79-year-old male was brought to the emergency room (ER) of our hospital after he fell and struck the occipital region of his head following excessive alcohol consumption. Four years prior, he had undergone anterior cervical discectomy and fusion of C5/6 and a magnetic resonance imaging (MRI) performed 3 years after this surgery indicated that he was suffering from degeneration of C6/7 intervertebral discs. After arriving at the ER, he presented motor impairment at level C7 and lower of manual muscle testing grade 1 as well as moderate loss of physical sensation from the trunk and peripheries of both upper limbs to the peripheries of both lower limbs (Frankel B). Cervical computed tomography (CT) indicated anterior dislocation of C6/7, and MRI indicated severe spinal cord edema. We performed manipulative reduction of C6/7 with the patient under general anesthesia. Next, we performed laminectomy on C5-T1 and posterior fusion on C6/7. Postoperative CT indicated that cervical alignment had improved, and MRI indicated that the spinal cord edema observed prior to surgery had been mitigated. Three months after surgery, motor function and sensory impairment of the lower limbs had improved, and the patient was ambulatory upon discharge from the hospital (Frankel D). In the present case, although C5 and 6 were rigidly fused, degeneration of the C6/7 intervertebral disc occurred and stability was compromised. As a result, even slight trauma placed a severe dynamic burden on the facet joint of C6/7, which led to dislocation.

Published: December 2015

ABSTRACT
Background: Mini-mental state examination (MMSE) scale measures cognition using specific elements that can be isolated, defined, and subsequently measured. This study was conducted with the aim to analyze the factorial structure of MMSE in a largely, illiterate, elderly population in India and to reduce the number of variables to a few meaningful and interpretable combinations. Methodology: Principal component analysis (PCA) was performed post-hoc on the data generated by a research project conducted to estimate the prevalence of dementia in four geographically defined habitations in Himachal Pradesh state of India. Results: Questions on orientation and registration account for high percentage of cumulative variance in comparison to other questions. Discussion: The PCA conducted on the data derived from a largely, illiterate population reveals that the most important components to consider for the estimation of cognitive impairment in illiterate Indian population are temporal orientation, spatial orientation, and immediate memory.

ABSTRACT
Background: Radiosurgery is an alternative to surgical resection of arteriovenous malformation (AVM). Very few studies have addressed the concern of radiation injury to the brain and its attendant adverse effects on cognitive function. Materials and Methods: This prospective study included all patients who underwent gamma knife radiosurgery (GKRS) at our institute for cerebral AVM between 2006 and December 2008 (n = 34). All patients underwent neuropsychological evaluation before the procedure. Neuropsychological evaluation was repeated in eighteen patients 2 years following GKRS. Clinical outcome, AVM obliteration, and factors influencing outcome were analyzed in these eighteen patients. Results: Before GKRS, more than 50% had significant impairment of neuropsychological functions compared to normal population norms. 66.6% achieved the excellent radiosurgical outcome. At 2 years follow-up, patients showed varied improvement in neuropsychological function in various categories. Pretherapeutic median value for percentage perseverative responses was 26.5 and at follow-up, it reduced to 18.2 (P = 0.039). Set shifting improved in 11 patients (61.1%), remained same in 5 patients (27.7%), and deteriorated in two patients (11.1%). Patients with a higher Spetzler-Martin grade AVM demonstrated a significantly more favorable shift in follow-up test values for set shifting function (P = 0.021). Patients with postradiation imaging changes had lesser tendency to improve in neuropsychological performance at follow-up. Conclusions: GKRS has no clinically harmful effect on cognitive and neuropsychological functioning in patients with brain AVM. On the contrary, there is an improvement in majority of patients at 2 years following radiosurgery when nidus is obliterated.
The dilemma of complicated shunt valves: How to identify patients with posthemorrhagic hydrocephalus after aneurysmatic subarachnoid hemorrhage who will benefit from a simple valve?

Published: December 2015

ABSTRACT
Background: Sophisticated shunt valves provide the possibility of pressure adjustment and antisiphon control but have a higher probability of valve dysfunction especially in a posthemorrhagic setting. The aim of the present study is to analyze the clinical outcome of patients with shunt dependent posthemorrhagic hydrocephalus after aneurysmatic subarachnoid hemorrhage (SAH) in order to identify patients who would benefit from a simple differential pressure valve. Methods: From 2000 to 2013, 547 patients with aneurysmatic SAH were treated at our institution, 114 underwent ventricular shunt placement (21.1%). 47 patients with available pre- and post-operative computed tomography scans, and an available follow-up of minimum 6 months were included. In order to measure the survival time which a nonprogrammable differential pressure valve would have had in an individual patient we defined the initial equalized shunt survival time (IESS). IESS is the time until surgical revisions of fixed differential pressure or flow-regulated valves for the treatment of over- or under-drainage as well as re-programming of adjustable valves due to over- or under-drainage. Results: Twenty patients were treated with fixed differential pressure valves, 15 patients were treated with flow-regulated valves, and 12 underwent ventriculoperitoneal (VP) shunt placement with differential pressure valves assisted by a gravitational unit. Patients who reacted with remarkable changes of the ventricular width after the insertion of external ventricular drainage (EVD), before shunt placement, showed a significantly longer IESS. Conclusions: Decline of the ventricular width after EVD placement was a predictor for successful VP shunt therapy in the later course of disease. Possibly, this could allow identifying patients who benefit from a simple differential pressure valve or a flow-regulated valve, and thus could possibly avoid valve-associated complications of a programmable valve in the later course of disease.

Authors: Rehman F. , Ajmal M. 
Published: December 2015

Abstract
Introduction: Malunion is the most frequent complication of fracture distal radius. Fracture malunion has been shown to associate with altered morphometric anatomy of distal radioulnar joint. Objective: This study aims to identify normal radiographic morphometry reference values and variations according to age and sex of distal radioulnar joint. This study was also carried out to determine the radiological correlation between normal and malunited distal radius in patient with unilateral malunited fracture to find out the effect of malunited fractured distal end of radius on the morphometric parameters of distal radioulnar joint. Materials and Methods: After twelve weeks of injury x-ray of injured wrist was compared with the radiograph of the contra lateral normal wrist for the difference in radial length, radial inclination, ulnar variance and palmar tilt. Results: Results of this study showed that there were signiicant difference in distal radius parameters between genders for both groups except for the difference in palmer tilt i.e. since value of P< 0.0001 so there is significant difference between two group 1% level of significant suggesting that with 99% confidence, there is significant difference between mean of normal male and female right wrist parameters of both age group except for palmer tilt. Similarly there were variations in all parameter measurements for those x-ray films showing severe malunion and signiicant differences were noted for all parameters distal radius between normal and malunited wrist in both age groups i.e. since value of P< 0.0001 so there is significant difference between two group 1% level of signiicant suggesting that with 99% conidence, there is signiicant difference for all parameters between mean of normal and malunion group. Conclusion: These results can be used in treatment of the malunited distal radius for correction of deformity at the wrist and achieving the best possible anatomical reduction in the young active patient and at minimizing the intervention in the low demand elderly patient with multiple comorbidities. These data also can be used for clinical research in the designing of wrist implants.
Unilateral incomplete bifid ureter: a case report
Authors: Kumar V. , Remya V. 
Published: December 2015

Abstract
Introduction: There are many congenital anomalies of ureter has been described in various literatures. This kind of anomaly is takes special importance because they remain asymptomatic or clinically present as pyelonephritis or urinary lithiasis. Even information of this kind of variation is very useful for radiological diagnosis. Case Report: We have observed a right sided incomplete bifid ureter during dissection done for under graduates in our institution. The renal pelvis and ureter up to the pelvic brim was double and they were fused at the level of pelvic brim to form a single ureter. It finally opens into left lateral angle of the base of the urinary bladder by a single opening. Discussion: Normally ureter is a long tubular structure measuring 25 -30 cm extending from renal pelvis to base of the urinary bladder, having thick muscular wall and a narrow lumen. Developmental variations like early splitting of ureteral bud can lead to such kind of anomaly. The incidence of bifid ureter is 0.5-3.0%. Thus early diagnosis of such asymptomatic conditions will prevent future complications and aid successful treatment.
PPAR γ agonist pioglitazone partially reverses hyperglycemia but improves semen quality and testicular histomorphometrics in alloxan-induced diabetic rats
Authors: Akinola O. , Sanusi S. , Ajayi T. , Olajide T. 
Published: December 2015

Abstract
Introduction: Chronic hyperglycaemia is associated with subfertility and infertility in male diabetic subjects, possible as a result of perturbed testicular antioxidant defence system. Recent evidence however shows that some testicular cells produce insulin and this raises the possibility of a role for this hormone in spermatogenesis. Moreover, isoforms of the nuclear peroxisome proliferator activated receptor (PPAR) have been detected in testicular tissue, suggesting a role for insulin sensitization in testicular function. Materials and Methods: In this study, we report the ameliorative effects of the PPAR γ agonist pioglitazone on testicular morphologic aberrations and impaired semen profile induced by diabetes in rats treated with intraperitoneal alloxan (150 mg/kg). Diabetic rats were randomly assigned to receive oral pioglitazone at 10 or 30 mg/kg once daily for 6 weeks. Weekly blood glucose measurement using the glucometer showed weak effect of pioglitazone on hyperglycaemia in our model. Results: Nonetheless, findings from caudal epididymal sperm analysis showed significantly high sperm density in the pioglitazone-treated rats at the two doses tested (P < 0.05 compared with diabetic controls). Moreover, pioglitazone at 10 mg/kg improved sperm motility and lowered the percentages of deformed and dead sperm cells in the treated diabetic rats. Haematoxylin and eosin (H&E) sections of the testes showed signiicantly reduced seminiferous tubule diameter and lumen size, as well as diminished height of the germinal epithelium in the untreated diabetic rats, but not in rats on pioglitazone intervention. Furthermore, Gordon and Sweet section of the testes showed thickened interstitial compartment only in the untreated diabetic group. Meanwhile, interstitial cells of Leydig appeared undisturbed in testicular sections of all the groups, while intratesticular testosterone levels measured by the enzyme immunoassay technique were not significantly different between the treated and control rats (P > 0.05). These findings show that increased sensitization of testicular cells to insulin signalling mediated by the PPAR γ agonist pioglitazone restores testicular histomorphometry and improves semen quality in diabetic rats, despite the weak effect of this drug on blood glucose. Conclusion: This suggests a role for insulin sensitizers and improved insulin signalling in the amelioration of testicular lesions and regulation of spermatogenesis in the diabetic state; and lends support for insulin at promoting testicular functions.

Authors: Leao S. , Queiroz A. , Souto M. , Almeida R. , Maciel D. , Rodrigues T. 
Published: December 2015

Abstract
Introduction: The ductus arteriosus is a blood vessel which connects the pulmonary artery to the aortic arch. This binding occurs opposite to the origin of left subclavian artery. The pulmonary trunk is an artery that carries deoxygenated blood from the right ventricle to the lungs. Objective: Make a morphometric study on the aorta and pulmonary artery beyond ductus arteriosus in a population of individuals between 9-26 weeks of gestation, constituting a database that can assist interventional surgeons for closure of the ductus arteriosus. Methods: It was measured weight, vertex-rump, vertex-heel lengths, head and chest circumferences, and anatomical measures concerning the ductus arteriosus of 44 human fetuses with gestational ages ranging from nine to 26 weeks. Inferential analysis was performed by Student's t test and Pearson's correlation (R) and the significance level was 0.05. Results: It was observed that, among the 44 fetuses, 22.72% had gestational age between nine and 14 weeks; 61.36% had between 15-20 weeks; and 15.90% had between 21-26 weeks of gestation. Regards morphological parameters, there are significant statistical differences for some parameters, such as diameter of the aorta+ pulmonary trunk (p < 0.0001); diameter of the aorta (p: 0.01); diameter of the pulmonary trunk (p: 0.007); diameter of the ductus base at the aorta (p < 0.0001). Conclusion: It is known that the earlier the correction of patent ductus arteriosus, increased patient survival. Therefore, it is necessary to develop instruments that allow the approach in extremely preterm infants with improved modes of treatment.

Published: December 2015

Abstract
Introduction: Microbiopsies of the M.adductor magnus, which is an important locomotor muscle were taken to study the effects of six weeks of moderate aerobic treadmill training and their reversibility after a training pause of nine weeks in a group of seven Foxhound-Boxer-Ingelheim Labrador crossbreds. Materials and Methods: To study changes of myofibre morphometry standard morphometric methods were applied using light and transmission electron micrographs. Results: The capillary density was higher in trained condition than in untrained condition and after the end of training. In contrast, the capillaries per iber as well as the capillary-to-iber ratio, the distance between neighboring capillaries and the capillary supply area showed no significant change. Smaller myofibre diameters were found in muscles of dogs in trained condition when compared to the untrained condition but not when compared to myofibres nine weeks after the end of training. Training led to increases in the volume fraction of mitochondria within myofibres and an increase of the surface density of cristae within the mitochondria. The ratio of the surface density to the volume fraction of the mitochondria increased in response to training. Except for the decrease in myofibre diameter, all of the reported changes were reversible and measurements nine weeks after cessation of training did not differ from measurements before training started. Conclusion: The results of this study emphasize the ability of dogs to rapidly and flexibly adjust locomotor muscles to changing exercise regimes by up-and down regulation of the number and inner structure of the mitochondria while the capillary network remains stable.

<p>The production of new digital cartography and ortophotos for the monuments of the Alhambra and Generalife is part of the SIALH project, which aims for the development of the Information System of the Alhambra. Map production in the area of the Alhambra is a challenge due to various factors such as the heritage value of the elements to be represented, the complex topography of the territory under study and the requirements of precision and detail exceeding the usual standards in cartography. The need for a multiscale cartography which must support both local-scale projects (up to 1:5000) and detailed planimetric surveys also<br />constitutes a challenge. The methodology employed combines aerial (LiDAR, digital photogrammetry) and ground sensors (laser scanning) to ensure maximum precision while emphasizing the role of data model as a key element for ensuring the multi-scale information and its usability in projects of very different scales.</p>

<p>The Museum of Casal De' Pazzi (Rome) is built since about ten years on a Pleistocene floor consisting in the ancient riverbed of the Aniene river, at about 200.000 bp. Since its opening, it has been characterized by a strong narrative approach, and communication effort. The digital project realized by the Italian CNR (Institut for Technology applied to Cultural Heritage) implies three applications: a flood simulation, to show the water refilling of the ancient riverbed; a<br />movie in computer-graphic, to be shown to the public, explaining neanderthal man and ancient elephant's life, and an edu-game, for children's learning, the Plei-stostation, implemented by touch-screen interaction dynamics.</p>

Evidently, it would be desirable that all these new elements could be accessed using any mobile device.<br />In this paper we study the main graphical languages to create 3D virtual museums and the process to adapt it to mobile devices. Specifically, we focus on the following technologies: Flash, VRML and X3D. We also explain the initial process to migrate the Virtual Museum of Iberian Art developed in a previous work in order to be renderized using a Samsung Galaxy Tab 10.1 with Android as operative system.</p>
Análisis dinámico de trayectorias laborales a través del concepto de flexiguridad
Authors: Alonso Dominguez Angel 
Published: December 2015

El artículo realiza un análisis dinámico para conocer si el mercado laboral español responde a las características de los mercados de trabajo transicionales, desde un enfoque de flexiguridad. A través de la Muestra Continua de Vidas Laborales se estudian las trayectorias de los trabajadores españoles durante el período 2007-2010, que abarca el final de la expansión de la economía española y el comienzo de la actual crisis de empleo. De la conjunción del tema elegido, el enfoque y la base de datos utilizada, resulta una perspectiva novedosa en nuestro país. Se ofrece evidencia empírica de la evolución de los episodios de empleo y paro, del grado de rotación del mercado laboral español y de las dificultades de determinados colectivos para realizar transiciones en y hacia el empleo. Los resultados muestran un mercado de trabajo en el que a) las transiciones se encuentran bloqueadas, y b) existe una alta inseguridad laboral.
