Longitudinal survey of humoral and cellular response to SARS-CoV-2 infection in children.

Background: Data regarding humoral and cellular response against SARS-CoV-2 in children are scarce. We analysed seroconversion rate, decrease of anti-RBD IgG antibodies over time and T-cell response in paediatric patients who suffered COVID-19.

Methods: Longitudinal study of paediatric patients COVID-19 diagnosed by positive molecular assay in nasopharyngeal swabs.

Clinical practice guidelines for transsexual, transgender and gender diverse minors.

Some people, including minors, have a gender identity that does not correspond to the sex assigned at birth. They are known as trans* people, which is an umbrella term that encompasses transgender, transsexual, and other identities not conforming to the assigned gender. Healthcare units for trans* minors require multidisciplinary working, undertaken by personnel expert in gender identity, enabling, when requested, interventions for the minor and their social-familial environment, in an individualized and flexible way during the gender affirmation path.

Exercise-Induced Hyponatremia: An Assessment of the International Hydration Recommendations Followed During the Gran Trail De Peñalara and Vitoria-Gasteiz Ironman Competitions.

Introduction: Hyponatremia often occurs during the practice of endurance sports. We evaluated the impact on hyponatremia of the hydration recommendations of the Third International Exercise-Associated Hyponatremia Consensus Development Conference 2015 (3IE-AHCD) during the 2017 marathon (GTP) and the triathlon (VGI).

Methods: Prospective study of GTP and VGI athletes participating in four information sessions in the months prior to the events, to explain that hydration should only be according to their level of thirst, per the recommendations of the 3IE-AHCD.

[Psychosocial assessment in transgender adolescents].

Objectives: To evaluate the psychosocial status of the patients who attend a paediatric endocrinology clinic due to gender incongruity (GI), and to establish the impact on this after one-year of cross hormonal therapy (CHT).

Material And Methods: An analytical and prospective study conducted on adolescents between 14 and 18 years old with GI, and who attended the Endocrinology clinic during 2018-2019. The sample included 23 transgender cases (16 male and 7 female cases) and 30 cisgender controls.

[Exercise as medicine in chronic diseases during childhood and adolescence].

Physical activity (PA) and exercise improve the overall quality of life, as well as prevent the onset of diseases in healthy children and adolescents, and as an aid to treat prevalent chronic diseases in childhood. PA and exercise are like medicine, but sedentary lifestyle and inactivity cause disease. In this article, the existing scientific evidence in this field is reviewed and recommendations for professionals involved in child health are updated.
