Gender and Age Distribution of Thyroid Nodules using Imaging Diagnostic and Management Modalities in Albania; Our data

Purpose: The purpose of this study was to evaluate gender and age distribution and the importance of imaging modalities in the evaluation and management of thyroid nodular disease in Albania nowadays. Material and method: The study analyzed the results of 310 patients (N=257 women; N=53 men), assessed at U. O. Clinic, American Hospital and Hygiea Hospital, Tirana, Albania during one year period; May 2015 – May 2016. The average age in the sample was 45.6 years. Thyroid nodules were found in 221 cases (185 females and 36 males). The patients had a standard ultrasound (US) of the thyroid; scintigraphy (SC) and ultrasound-guide fine needle aspiration biopsy (US-FNAB) when indicated. Results: The study shows that nodular disease of the thyroid was found in 84 % of women patients, and in 16 % of men patients. The largest presence of nodules was at the age group of 41-49 years. Moreover, this survey showed that ultrasound can help to distinguish nodules that are definitely benign and those with suspicious features that may require further investigation under FNAB. Some statistically significant connections were found between ultrasound characteristics and FNAB. Conclusion: Females were vast majority of patients as in regards of gender with 84 % of total sample population in the study of 310 subjects. And group age of 41-49 years old were more affected. Ultrasound and other imaging modalities are reliable methods for diagnosis and management of thyroid nodules, including patients' selection to undergo through FNAB. SC was indicated to evaluate the functional features of a nodule, especially in the presence of a low TSH value. In Albania these modalities are now used by many trained medical staff thus offering quality medical service to our patients over all.

An analysis of the Spanish high capacity road network criticality

The analysis of complex networks has been carried out in different fields using an ample variety of method and concepts. Recently, in the general literature of regional economics, the concepts of resilience, connectivity, vulnerability and criticality have been gaining their momentum. The aim of this paper is to provide an analytical framework, using well-known accessibility indicators, in order to calculate the critical links or road sections of the Spanish high-capacity road network. Our analysis will be based on approximately four hundred sections that will be classified in five different groups according to their criticality degree in the whole network. Our analysis will be complemented with the comparison of the results obtained in five different scenarios, namely the average criticality using the effects on the whole country, Madrid, Barcelona, Valencia and Pontevedra. Furthermore, the paper will also analyze what kind of intrinsic characteristics of the sections favor or not the links’ criticality using a method based on a classification and regression tree. This analysis is crucial to understand other important concepts that are recently being studied in network and spatial economics, like, for example, resilience and vulnerability. It is concluded that the number of relations or routes, being a trunk or not, the road density and the time to Madrid capital play an important role in the criticality of the roads section in the high capacity road network.Depto. de GeografíaFac. de Geografía e HistoriaTRUEpu
