A percepção de adolescentes e de pais sobre decisão e autonomia

This study attempted to investigate decisional autonomy in Turkish adolescents from 12 to 18 years. The Perspectives on Adolescent Decision Making (PADM) questionnaire was administered to 372 middle class adolescents who attend middle and high schools and to their parents. The PADM assess if adolescents decide for themselves, or parents impose restrictions or adolescents and parents have arguments about the topic. MANOVA analyzes were used. Results showed that affirmative answers increased with age. From adolescent and parents' perspectives adolescent decisional autonomy grows with age, parental control decreases, conflicts between them tended to decrease, on the perspective of parents. There was minor gender differences: girls have higher level of decisional autonomy; boys experience more conflict. Adolescents' decisional autonomy expectations tended to be higher than those of parents. Fathers' and mothers' perspectives on decisional autonomy were very similar. The results support the new family model proposed by Kaðýtçýbaþý.Estudo objetivou investigar autonomia de decisão de adolescentes turcos de 12-18 anos de idade. Questionário PADM (Perspectivas na Tomada de Decisões por Adolescentes) foi administrado a 372 adolescentes de classe média, alunos de ensino fundamental e médio e a seus pais. O PADM verifica se adolescentes decidem por si mesmos ou se os pais impõem restrições, também se discutem o assunto. Foram usadas análises MANOVA. Os resultados mostraram que respostas afirmativas aumentam com a idade. Na perspectiva de pais e adolescentes a autonomia para tomada de decisões aumenta com a idade, o controle parental diminui, conflitos tendem a diminuir. Houve pequena diferença de gênero: meninas têm maior nível de autonomia decisional, meninos experimentam mais conflitos. As expectativas de autonomia decisional dos adolescentes tendem a ser maiores que as dos pais. Perspectivas de pais e mães sobre autonomia foram bastante similares; os resultados suportam o modelo de família proposto por Kaðýtçýbaþý

Significance of Metastatic Lymph Node Ratio on Stimulated Thyroglobulin Levels in Papillary Thyroid Carcinoma after Prophylactic Unilateral Central Neck Dissection

Background: Prognostic significance of metastatic central lymph node ratio (CLNR) in papillary thyroid carcinoma (PTC) remains unknown. Because postsurgical detectable stimulated thyroglobulin (DsTg) after radioiodine ablation may imply persistent or recurrent disease, we evaluated the association between CLNR and rate of DsTg in patients with PTC who underwent unilateral prophylactic central neck dissection. Methods: To be eligible for analysis, the prophylactic central neck dissection specimen had to contain ≥3 central lymph nodes (CLNs) with ≥1 harboring metastasis. Of 129 specimens, 51 (39.5%) were eligible. CLNR was calculated as follows: (number of metastatic CLNs/number of CLNs retrieved) × 100. They were categorized into group 1 (CLNR 66.67%) (n = 22). Postablation sTg level was measured 6 months after radioiodine ablation. A multivariate analysis was conducted to identify factors for postablation DsTg. Results: Young age, palpable neck swelling, large tumor size, advanced tumor, node, metastasis system (TNM) stage, and large number of metastatic CLNs were significantly associated with high CLNR (Ppublished_or_final_versionSpringer Open Choice, 21 Feb 201

Exploración vocacional en adolescentes: evaluación de una intervención en clase

Analisa-se o impacto de uma intervenção psicológica na exploração e tomada de decisão vocacional em adolescentes portugueses. Em contexto curricular e de classe, desenvolveram-se actividades de exploração do meio e do Eu com 39 alunos e 43 alunas do 9o ano, entre 13 e 17 anos (M=14,4, DP=0,95). Em um design pré/pós-teste, aplicaram-se o Career Exploration Survey (CES) e o Career Decision Difficulties Questionnaire (CDDQ). Os resultados do teste do sinal evidenciaram ganhos significativos (p<0,01) nas dimensões de exploração e diminuição significativa da falta de informação profissional (p<0,01) e do total das dificuldades de decisão (p<0,05). Observou-se um padrão de correlações negativas (ró de Spearman) entre as duas medidas vocacionais, evidenciando uma relação entre a informação explorada na intervenção e a diminuição das dificuldades de decisão por falta de motivação. Em geral, os resultados suportam a importância do papel da exploração da carreira na diminuição das dificuldades de tomada de decisão.This study analyses the impact of a psychological intervention to promote vocational exploration and decisionmaking in Portuguese adolescents. Activities to foster exploration of self and environment were developed in a classroom program with 39 boys and 43 girls, all 9th grade students, between 13 and 17 years of age (M=14,4, SD=0.95). Following a pre/post-test design, the Career Exploration Survey (CES), and the Career Decision Difficulties Questionnaire (CDDQ) were administered. Results of sign-test showed significant increments (p<0.01) in all of the exploration dimensions, significant reduction of lack of occupational information (p<0.01) and of the total of career decision-making difficulties (p<0.05). Negative correlations (Spearman’s rho) between the two career measures was observed, evidencing a relationship between information explored during intervention and decreased difficulty with decision-making due to lack of motivation. In general, results support the importance of career exploration on diminishing decision-making difficulties.Evalúa-se el impacto de una intervención psicológica que fomenta la exploración y la decisión vocacional en adolescentes portugueses.

Transmitted antiretroviral drug resistance mutations in newlydiagnosed HIV-1 positive patients in Turkey

Introduction: The objective of this study was to determine the transmitted drug resistance mutations (TDRMs) in newly diagnosed HIV-1 positive patients in Turkey. Materials and Methods: The study was carried out between 2009 and 2014 and antiretroviral naïve 774 HIV-1 infected patients from 19 Infectious Diseases and Clinical Microbiology Departments in Turkey were included; gender: 664 (86%) male, median age: 37 (range; 1–77), median CD4+T-cell: 360 (range; 1–1320) count/mm3, median HIV-RNA load: 2.10+E6 (range; 4.2+E2–7.41+E8) IU/mL. HIV-1 drug resistance mutations were detected by population based sequencing of the reverse transcriptase (codon 41–238) and protease (codon 1–99) domains of pol gene of HIV-1, and analyzed according to the criteria by the World Health Organization 2009 list of surveillance drug resistance mutations [1]. Results: The patients had TDRMs to NRTIs (K65R, M184V), NNRTIs (K101E, K103N/S, G190A/E/S, Y181I/C, Y188H/L) and PIs (M46L, I54V, L76V, V82L/T, N83D, I84V, L90M). The prevalence of overall TDRMs was 6.7% (52/774). Resistance mutations were found to be 0.7% (6/774), 4.1% (32/774) and 2.1% (17/774) to NRTIs, NNRTIs and PIs drug groups, respectively. Three patients had NRTIs+NNRTs resistance mutations (M184V+K103N) as multi-class drug resistance. However, thymidine analogue resistance mutations (TAMs) determined two distinct genotypic profiles in the HIV-1 reverse transcriptase: TAM1: M41L, L210W and T215Y, and TAM2: D67N, K70R, K219E/Q, and T215F. The prevalence of TAM1 and TAM2 were 7.7% (60/774) and 4.3% (34/774), respectively. Conclusions: The TDRMs prevalence of antiretroviral naïve HIV-1 infected patients may be suggested current situation of Turkey. These long-term and large-scale results show that the resistance testing must be an integral part of the management of HIV infection in Turkey

Mitochondrial physiology

As the knowledge base and importance of mitochondrial physiology to evolution, health and disease expands, the necessity for harmonizing the terminology concerning mitochondrial respiratory states and rates has become increasingly apparent. The chemiosmotic theory establishes the mechanism of energy transformation and coupling in oxidative phosphorylation. The unifying concept of the protonmotive force provides the framework for developing a consistent theoretical foundation of mitochondrial physiology and bioenergetics. We follow the latest SI guidelines and those of the International Union of Pure and Applied Chemistry (IUPAC) on terminology in physical chemistry, extended by considerations of open systems and thermodynamics of irreversible processes. The concept-driven constructive terminology incorporates the meaning of each quantity and aligns concepts and symbols with the nomenclature of classical bioenergetics. We endeavour to provide a balanced view of mitochondrial respiratory control and a critical discussion on reporting data of mitochondrial respiration in terms of metabolic flows and fluxes. Uniform standards for evaluation of respiratory states and rates will ultimately contribute to reproducibility between laboratories and thus support the development of data repositories of mitochondrial respiratory function in species, tissues, and cells. Clarity of concept and consistency of nomenclature facilitate effective transdisciplinary communication, education, and ultimately further discovery

Effect of laser welding parameters on fusion zone morphological, mechanical and microstructural characteristics of AISI 304 stainless steel

WOS: 000262184000021Nowadays, the Nd:YAG laser has been a promising key tool for joining thin components. In this research, mechanical and microstructural properties of laser welded thin austenitic stainless steel sheets were investigated with experimental investigations, as a function of laser welding parameters. Butt welded joints were made using a Nd:YAG laser in the pulsed wave mode. The appropriate laser welding parameters were found in order to obtain quality and strong weld seam. The pulsed laser seam welding process is controlled by a variety of parameters. We focus on the effects of the several processing parameters on mechanical and microstructural characteristics of joint and weld quality. The aim of this research was to evaluate the influence of these processing parameters on joint strength and microstructure. And also we examined the weldability of stainless steels in butt joint Configuration by a pulsed Nd:YAG laser beam

Usefulness of the Autologous Serum Test for the Diagnosis of Chronic Idiopathic Urticaria

Background: The majority of chronic urticaria cases are chronic idiopathic urticaria (CIU) with no specific identifiable etiology. The role of autoantibodies in such cases remains controversial. Objective: This study determined the positivity rate of autologous serum tests in CIU patients. Methods: This study was performed on 30 patients with CIU and 30 individuals without any systemic or dermatologic disease. After the volar parts of right and left forearms were cleansed, 0.05 ml serum physiologic and 0.05 ml autologous serum were injected intradermally on the right forearm 5 cm apart from each other, resulting in the formation of small papules; meanwhile, 0.05 ml histamine alone was injected to the left forearm. The test results were evaluated after 30 minutes as positive in positive cases. Results: The autologous serum test produced significant and non-significant results in patients with CIU and controls, respectively. The positivity rates of the autologous serum test in the CIU and control groups were 53.3% and 26.6%, respectively. There was no relationship between autologous serum test positivity and sex in either group. In male patients with CIU, positive results ranged widely with age, while in female patients, positive results were mainly observed at younger ages with a narrow age range. Conclusion: The autologous serum test is a useful test in the diagnosis and treatment of CIU as well as the selection of immunotherapy, especially in patients refractory to classic therapy
