TRANSITION IN ENDOCRINOLOGY: Hypogonadism in adolescence.

Puberty is a remarkable developmental process with the activation of the hypothalamic-pituitary-gonadal axis culminating in reproductive capacity. It is accompanied by cognitive, psychological, emotional, and sociocultural changes. There is wide variation in the timing of pubertal onset, and this process is affected by genetic and environmental influences. Disrupted puberty (delayed or absent) leading to hypogonadism may be caused by congenital or acquired etiologies and can have significant impact on both physical and psychosocial well-being. While adolescence is a time of growing autonomy and independence, it is also a time of vulnerability and thus, the impact of hypogonadism can have lasting effects. This review highlights the various forms of hypogonadism in adolescence and the clinical challenges in differentiating normal variants of puberty from pathological states. In addition, hormonal treatment, concerns regarding fertility, emotional support, and effective transition to adult care are discussed.

Stability and consistency of coping in adolescence: A longitudinal study

This study analyzed stability and consistency of coping among adolescents. The objectives were twofold: a) to analyze temporal stability and cross-situational consistency of coping responses after a 17- month interval, taking into account gender, age and type of stressor. b) To analyze the relative weight of contextual versus dispositional factors in predicting future coping. A cohort of 341 adolescents (51% girls and 49% boys aged between 12 and 16) were assessed twice by means of the Coping Responses Inventory - Youth. The results indicated that the coping responses were quite stable over time at the group level, but with important within-subject differences. Girls showed slightly more stability than boys. Among the girls, Avoidance coping showed as much stability as consistency and Approach coping showed more stability than consistency. Among the boys, Avoidance coping showed more stability than consistency, and Approach coping showed both low stability and low consistency. Among the boys, the coping used at Time 1 barely predicted that used at Time 2; in contrast, among the girls, the type of coping used in the past, especially Avoidance coping, predicted the coping that would be used in the future.

Author Rights vs Self-Archiving in Spanish Scientific Journals

The paper analyzes publishers" copyright policies and self-archiving conditions of Spanish scientific journals. Data are extracted from the directory DULCINEA that contains information of 1318 Spanish journals, of which 775 (61%) allow some form of self-archiving to be about 60% of the post-print version and allowing them 87% of the deposit of the version of record. In 72% of journals the deposit can be performed immediately after publication and in 16% after article acceptance. 72% of the journals are freely available without charge to the user this figure raises up to 86% if free access after an embargo is considered. Only 18% of the journals use Creative Commons licenses. The adoption of different open access journals model in Spain is favorable, however there is still a high percentage of journals (39%) that do not provide any information about authors and publishers rights and that difficult or inhibits reuse of published articles.

Positive Self-Image in Tournaments

This article analyzes the implications of worker overestimation of productivity for firms in which incentives take the form of tournaments. Each worker overestimates his productivity but is aware of the bias in his opponent's self-assessment. The manager of the firm, on the other hand, correctly assesses workers' productivities and self-beliefs when setting tournament prizes. The article shows that, under a variety of circumstances, firms can benefit from worker positive self-image. The article also shows that worker positive self-image can improve welfare in tournaments. In contrast, workers' utility declines due to their own misguided choices.

Listening to parents: The role of symptom perception in pediatric palliative home care.

OBJECTIVE: This study analyzes symptom perception by parents and healthcare professionals and the quality of symptom management in a pediatric palliative home care setting and identifies which factors contribute to a high quality of palliative and end-of-life care for children. METHODS: In this retrospective, cross-sectional study, parents were surveyed at the earliest three months after their child's death. All children were cared for by a specialized home pediatric palliative care team that provides a 24/7 medical on-call service. Questionnaires assessed symptom prevalence and intensity during the child's last month of life as perceived by parents, symptom perception, and treatment by medical staff. The responses were correlated with essential palliative care outcome measures (e.g., satisfaction with the care provided, quality-of-life of affected children and parents, and peacefulness of the dying phase). RESULTS: Thirty-eight parent dyads participated (return rate 84%; 35% oncological disorders). According to parental report, dyspnea (61%) and pain (58%) were the dominant symptoms with an overall high symptom load (83%). Pain, agitation, and seizures could be treated more successfully than other symptoms. Successful symptom perception was achieved in most cases and predicted the quality of symptom treatment (R 2, 0.612). Concordant assessment of symptom severity between parents and healthcare professionals (HCPs) improved the satisfaction with the care provided (p = 0.037) as well as the parental quality-of-life (p = 0.041). Even in cases with unsuccessful symptom control, parents were very satisfied with the SHPPC team's care (median 10; numeric rating scale 0-10) and rated the child's death as highly peaceful (median 9). Significance of the results: The quality and the concordance of symptom perception between parents and HCPs essentially influence parental quality-of-life as well as parental satisfaction and constitute a predictive factor for the quality of symptom treatment and palliative care.

Fourier self-deconvolution in coherent anti-Stokes Raman scattering spectrum analysis

Coherent anti-Stokes Raman scattering (CARS) microscopy is rapidly developing into a unique microscopic tool in biophysics, biology and the material sciences. The nonlinear nature of CARS spectroscopy complicates the analysis of the received spectra. There were developed mathematical methods for signal processing and for calculations spectra. Fourier self-deconvolution is a special high pass FFT filter which synthetically narrows the effective trace bandwidth features. As Fourier self-deconvolution can effectively reduce the noise, which may be at a higher spatial frequency than the peaks, without losing peak resolution. The idea of the work is to experiment the possibility of using wavelet decomposition in spectroscopic for background and noise removal, and Fourier transformation for linenarrowing.

Physical activity in adolescence - with special reference to cardiovascular health

Liikunta ja sydän- ja verisuoniterveys nuorilla Aikuisiällä ilmenevien sydän- ja verisuonisairauksien kehitys alkaa lapsuudessa. Vähäinen liikunta lisää vaaraa sairastua sydän- ja verisuonisairauksiin sekä vaikuttaa haitallisesti näiden sairauksien riskitekijöihin läpi elämän. Tämän tutkimuksen tavoitteena oli tutkia nuorten liikuntaa ja sen yhteyttä sydän- ja verisuoniterveyteen. Sydän- ja verisuoniterveyttä tutkittiin riskitekijöiden sekä valtimon laajentumiskyvyn avulla. Tutkittavat koostuivat nuorista, jotka osallistuivat pitkäaikaisen sepelvaltimotaudin ehkäisytutkimuksen (STRIP) 13-vuotistutkimuskäynnille ja jotka raportoivat vapaa-ajan liikuntatottumuksensa (n=560). Liikunnan lisäksi nuorten pituus, paino, verenpaine ja olkavaltimon laajentumiskyky mitattiin sekä analysoitiin laboratorionäytteitä (otettiin verinäyte) ja selvitettiin ruoankäyttöä. Vähäinen vapaa-ajan liikunta oli yleistä etenkin tytöillä. Vapaa-ajallaan vähän liikkuvat pojat viettivät enemmän aikaa televisio- ja tietokoneruudun ääressä kuin vapaa-ajallaan paljon liikkuvat pojat. Äidin, toisin kuin isän, vapaa-ajan liikunta ja paino olivat yhteydessä lapsen vapaa-ajan liikuntaan. Vähän liikkuvat tytöt olivat olleet jo kahden vuoden iästä saakka useammin ylipainoisia kuin runsaammin liikkuvat ikätoverinsa. Sydän- ja verisuonisairauksien riskitekijöiden kasautuminen oli tavallisempaa vähän kuin paljon liikkuvilla nuorilla. Vähän liikkuvilla pojilla oli lisäksi huonompi olkavaltimon laajentumiskyky kuin paljon liikkuvilla pojilla. Tämä on tärkeä löydös, koska valtimon laajentumiskyky kuvannee sydän- ja verisuoniterveyttä jo ennen rakenteellisten muutosten ilmaantumista. Useat nuoret, etenkin tytöt, liikkuivat vähän vapaa-ajallaan. Vähäisellä vapaa-ajan liikunnalla oli haitallinen yhteys sydän- ja verisuonisairauksien riskitekijöihin sekä valtimon laajentumiskykyyn. Nuorten kannustaminen liikunnalliseen elämäntapaan on erittäin tärkeää sydän- ja verisuoniterveyden edistämiseksi sekä nuoren että kansanterveyden kannalta.

Un estudio transversal sobre la percepción de la vitalidad etnolingüística en jóvenes y adultos de Catalunya = A cross-sectional study on ethnolinguistic vitality perception in young and adulthood people from Catalonia

El estudio utiliza un diseño transversal en el campo de la percepción de la vitalidad etnolingüística. Es el primero que compara la percepción de la vitalidad etnolingüística, así como los factores asociados, entre adultos jóvenes y adultos, en relación con los grupos castellanohablantes y catalanohablantes de la Comunidad Autónoma de Cataluña. Para ello, se aplicó el 'Cuestionario de vitalidad etnolingüística subjetiva' (CVS) a una muestra de 527 participantes, 268 jóvenes y 259 adultos, de los cuales se seleccionó una submuestra de individuos que tenían el catalán como lengua materna y se identificaban como catalanes (n=301). En ambas muestras se aduce una tendencia a descriminar favorablemente la vitalidad percibida por el grupo catalán, aspecto que se acentúa significativa en el grupo de jóvenes estudiados en relación al grupo de edad de los adultos. Se discuten los resultados según las repercusiones teóricas y pragmáticas de los estudios realizados en el ámbito de la comunicación intergrupal

The role of self-knowledge in aristotelian friendship

This paper discusses the capital role that friendship plays in moral self-knowledge within Aristotelian Ethics. It focuses on the different ways in which a friend may shed light on the understanding of our behavior. Great attention is paid to the accounts of certain commentators (especially, of Richard Kraut and Anthony Kenny) on this subject. The paper tries to provide a conciliatory interpretation between views on self-knowledge that are, only in appearance, irreconcilable.
