Urology Journal , 2013,
Abstract: PURPOSE: To evaluate the efficacy of needle biopsy for diagnosing Wilmstumor (WT) before chemotherapy. MATERIALS AND METHODS:We reviewed our institutional experience with Tru-Cut biopsy of pediatric renal masses in patients who subsequently underwent nephrectomy. We compared biopsy pathology with nephrectomy specimens to determine if biopsy accurately predicted final pathology. RESULTS: Seven children underwent Tru-Cut renal mass biopsy followed by surgical resection. In 4 patients, the final biopsy pathology was definitively read as WT and in 3 subjects, the pathology was read as WT versus hyperplastic nephrogenic rest. In all 7 patients, the nephrectomy pathology confirmed a diagnosis of WT. There were no complications after biopsy, and no patients have had local or regional recurrence.CONCLUSION: In our experience, pre-therapy Tru-Cut biopsy safely provides an adequate specimen for pathologic review in diagnosing WT.
Dysplastic lesions of the cervix evolution after conservative excision

Jurnalul de Chirurgie , 2012,
Abstract: This study analyzes the evolution of dysplastic lesions after conservative excision treatment (Large Loop Excision Transformation Zone – LLETZ and conization). METHODS: We performed an observational study on a group of 332 patients, diagnosed and treated for cervical dysplasia at Cuza Vod ” Obstetrics and Gynecology Clinic Hospital Suceava between 2006 and 2011. RESULTS: High grade cervical squamous intraepithelial lesion (HSIL) accounted for 88 patients (26.5%), low grade cervical squamous intraepithelial lesion (LSIL) for 92 patients (27.71%), atypical squamous cells of undetermined significance (ASC-US) for 69 patients (20.78%) and squamous cell carcinoma accounted for 5 patients (1.5%) of Pap smears. Statistical results showed high frequency of reduced intraepithelial neoplasia (CIN 1) in the age of 40 years (53%). Type correlation with histopathological diagnosis of HPV infection showed increased percentage of HPV-HR infection from 58% in B, 80% in CIN 1, CIN 2 and 92% to 100% in CIN 3, CIS and CCS. CONCLUSIONS: Histopathological diagnosis of CIN 1 indicating a manifestation of HPV infection, lesion which rarely progress to cancer. On contrary the CIN 2 and CIN 3 lesions have to be treated as potentially malignant.
Importancia de la nutrición en enfermos con encefalopatía hepática

Nutrición Hospitalaria , 2012,
Abstract: protein calorie malnutrition is frequently a complication in the chronic liver disease patient and is considered to be a negative prognostic factor. anorexia and several other endocrine metabolic complications produce an hypermetabolic state that needs more caloric intake. hepatic encephalopathy is one of the developments possible in patients with descompensated cirrhosis. the wellknown role of ammonia in the pathogenesis of hepatic encephalopathy has determined a restriction in dietary protein along many decades. nevertheless, there is no evidence about a low protein diet being better in the outcome of hepatic encephalopathy, it worsens, moreover, the nutritional status and helps in the development of many nutritional related complications. this article reviews the use of oral branched-chain amino acids and proteins of different sources, probiotics, synbiotics, antioxidants, oral l-ornithine l-aspartate and acetyl-l-carnitine in patients with hepatic encephalopathy.
Importancia de la nutrición en enfermos con encefalopatía hepática Importance of nutritional support in patients with hepatic encephalopathy

Abstract: La desnutrición es una complicación frecuente que influye negativamente en el pronóstico del enfermo con cirrosis hepática. La disminución de la ingesta junto con la aparición de diversas alteraciones endocrino-metabólicas condicionan un estado hipercatabólico que precisa de un mayor aporte energético. Una de las complicaciones que puede aparecer en la fase de cirrosis descompensada es la encefalopatía hepática. El reconocido papel del amonio en la patogenia de la encefalopatía hepática ha condicionado durante muchos a os una restricción en el aporte de proteínas de estos enfermos. Sin embargo, no existe evidencia de que una dieta baja en proteínas mejore el curso de la encefalopatía hepática y sí de que empeore el estado nutricional y favorezca la aparición de distintas complicaciones relacionadas con la desnutrición. En este trabajo, se revisa el uso de aminoácidos ramificados y de proteínas de diferente origen, probióticos y simbióticos, antioxidantes, L-Ornitina-L-Aspartato, acetil-L-carnitina en enfermos con encefalopatía hepática.

Biomolecular nonlinear dynamic mechanisms as a foundation for human traits of information processing machine
Nicholas G. Rambaidi
Discrete Dynamics in Nature and Society , 2001, DOI: 10.1155/s1026022601000310
Abstract: A pseudo-biological paradigm in information processing launched by McCulloch and Pitts in the early 1940s has been advanced during the last decades. Different attempts were made based on these developments to design operational information processing devices capable of solving problems of high computational complexity.
An instrument to measure job satisfaction of nursing home administrators
Nicholas G Castle
BMC Medical Research Methodology , 2006, DOI: 10.1186/1471-2288-6-47
Abstract: The NHA-JSQ subscales were developed from pilot survey activities with 93 administrators, content analysis, and a research panel. The resulting survey was sent to 1,000 nursing home administrators. Factor analyses were used to determine the psychometric properties of the instrument.Of the 1,000 surveys mailed, 721 usable surveys were returned (72 percent response rate). The factor analyses show that the items were representative of six underlying factors (i.e., coworkers, work demands, work content, work load, work skills, and rewards).The NHA-JSQ represents a short, psychometrically sound job satisfaction instrument for use in nursing homes.Job satisfaction is defined as "the favorableness or unfavorableness with which employees view their work" [1]. Some recent research would suggest that job satisfaction of employees within an organization is related to an organization's ability to change [2]. Since a consistent theme in the literature for the past 20 years (or more) has been the inability of some nursing homes to change in a meaningful way, especially in the area of quality of care [3], in this context improving job satisfaction may be important in improving some aspects of the industry.Job satisfaction of nursing home administrators (NHAs) may be especially important, because administrators can have a pervasive influence on facility performance and quality of care [4]. Castle [5], for example, has shown a positive association between NHA turnover and the resident outcomes of catheterization, restraint use, pressure ulcers, psychoactive medications, and quality of care deficiencies. Smith, Shortell, and Saxberg describe NHAs as "the critical variable affecting quality of care" [6]. Singh and Schwab [7] have examined the organizational destabilization that can occur when NHAs turnover [7]. Resident satisfaction would also appear to be influenced by NHAs [8]. Given the importance of NHAs and their potential impact on quality, a valid and reliable instrument to ass

Moments of a length function on the boundary of a hyperbolic manifold
Nicholas G. Vlamis
Mathematics , 2013, DOI: 10.2140/agt.2015.15.1909
Abstract: In this paper we will study the statistics of the unit geodesic flow normal to the boundary of a hyperbolic manifold with non-empty totally geodesic boundary. Viewing the time it takes this flow to hit the boundary as a random variable, we derive a formula for its moments in terms of the orthospectrum. The first moment gives the average time for the normal flow acting on the boundary to again reach the boundary, which we connect to Bridgeman's identity (in the surface case), and the zeroth moment recovers Basmajian's identity. Furthermore, we are able to give explicit formulae for the first moment in the surface case as well as for manifolds of odd dimension. In dimension two, the summation terms are dilogarithms. In dimension three, we are able to find the moment generating function for this length function.
