    Family relationships during leisure time in adolescence have the potential to promote positive development, particularly in terms of autonomy. However, the scientific literature that links specifically positive family leisure to the development of adolescent autonomy is scarce, and lower when analyzing the role of frustration in leisure time. Grounded in Self-Determination Theory (SDT) this article examines the potential relationship between positive frustration in family leisure time and the promotion of adolescent autonomy. For that purpose, the manuscript addresses four objectives to be discussed consecutively: (1) to delimit the concept of adolescent autonomy and point out the difficulty of parental support; (2) to explore positive frustration, a concept aligned with Csikszentmihalyi’s theory of flow, as a construct that can promote socio-emotional development in adolescence; (3) to describe the components of family leisure; and (4) to understand how the experience of optimal frustration may be linked to the development of adolescent autonomy during family leisure time. From this central question, several additional inquiries emerge: the interplay of frustration and failure in adolescence, the importance of parents and adolescents spending quality time together, the enjoyment in structured family leisure time, the autonomy-supportive parenting in leisure time activities in relation to daily activities, the need to strengthen adolescent bonds developed in infancy, and the complexity of paternal and maternal autonomy granting

    Tumor growth is a surface phenomenon of the molecular beam epitaxy universality class in which diffusion at the surface is the determining factor. This Letter reports experiments performed in mice showing that these dynamics can, however, be changed. By stimulating the immune response, we induced strong neutrophilia around the tumor. The neutrophils hindered cell surface diffusion so much that they induced new dynamics compatible with the slower quenched-disorder Edwards-Wilkinson universality class. Important clinical effects were also seen, including remarkably high tumor necrosis (around 80%-90% of the tumor), a general increase in survival time [the death ratio in the control group is 15.76 times higher than in the treated group (equivalent to a Cox's model hazard ratio of 0.85; 95% confidence interval 0.76-0.95, p=0.004)], and even the total elimination of some tumors

    MCP-1 (monocyte chemoattractant protein-1) is a proinflammatory cytokine involved in chemotaxis of monocytes. In several diseases, such as acute coronary syndromes and heart failure, elevated MCP-1 levels have been associated with poor outcomes. Little is known about MCP-1 in cirrhosis. AIM: To investigate the relationship between MCP-1 and outcome in decompensated cirrhosis. METHODS: Prospective study of 218 patients discharged from hospital after an admission for complications of cirrhosis. Urine and plasma levels of MCP-1 and other urine proinflammatroy biomarkers: osteopontin(OPN), trefoil-factor3 and liver-fatty-acid-binding protein were measured at admission. Urine non-inflammatory mediators cystatin-C, β2microglobulin and albumin were measured as control biomarkers. The relationship between these biomarkers and the 3-month hospital readmission, complications of cirrhosis, and mortality were assessed. RESULTS: 69 patients(32%) had at least one readmission during the 3-month period of follow-up and 30 patients died(14%). Urine MCP-1 and OPN levels, were associated with 3-month probability of readmission (0.85 (0.27-2.1) and 2003 (705-4586) ug/g creat vs 0.47 (0.2-1.1) and 1188 (512-2958) ug/g creat, in patients with and without readmission, respectively; p<0.05; median (IQR)). Furthermore, urine levels of MCP-1 were significantly associated with mortality (1.01 (1-3.6) vs 0.5 (0.2-1.1) μg/g creat, in dead and alive patients at 3 months; p<0.05). Patients with higher levels of urine MCP-1 (above percentile 75th) had higher probability of development of hepatic encephalopathy, bacterial infections or AKI. Urine MCP-1 was an independent predictive factor of hospital readmission and combined end-point of readmission or dead at 3 months. Plasma levels of MCP-1 did not correlated with outcomes. CONCLUSION: Urine, but not plasma, MCP-1 levels are associated with hospital readmission, development of complications of cirrhosis, and mortality. These results suggest that in cirrhosis there is an inflammatory response that is associated with poor outcomes

    Not everything helps the same for everyone: relevance of extracurricular activities for academic achievement

    Abstract Participation in organized Extracurricular Activities has contributed to improve academic achievement. However, this does not happen in the same way; it depends on sex, age, or parental educational level. Our objective is to know the importance of these factor interactions’ in the explanation of academic achievement. The sample consisted of 1148 adolescents, aged between 12 and 18 years, 52% of whom were female. Participants completed the Extracurricular Activities questionnaire, and academic and sociodemographic data were collected. The results show that differences in academic achievement depend on the adolescent stage. In early adolescence, girls improve in academic achievement, as well as with better parental education, reading of books and activity duration. On the contrary, in the middle and late adolescence, academic achievement improves with not participating in collective sports and reduced activity breadth, although parental educational level follows the same trend as in the early adolescence. These results reinforce the evolutionary hypothesis of specialization in the choice of activities throughout adolescence. In this sense, some proposals for schools that advocate for greater integration of curricular and non-curricular elements are discussed

    This work reports the possible cure of a 56-year-old patient with advanced hepatocarcinoma. Intense peritumoral neutrophilia was achieved by administering granulocyte colonystimulating factor (G-CSF), an experimental treatment based on the theory of universal tumour dynamics. After the first 8-week cycle of treatment, the patient’s α-fetoprotein (AFP) levels were reduced to normal and his general condition improved sufficiently to allow him to return to work. Following a second cycle of treatment, administered because of doubt regarding the tumoral or inflammatory nature of the now smaller liver mass, the patient’s AFP levels remained normal and he continued to enjoy good general health

    The Universal Dynamics of Tumor Growth

    Scaling techniques were used to analyze the fractal nature of colonies of 15 cell lines growing in vitro as well as of 16 types of tumor developing in vivo. All cell colonies were found to exhibit exactly the same growth dynamics—which correspond to the molecular beam epitaxy (MBE) universality class. MBE dynamics are characterized by 1), a linear growth rate, 2), the constraint of cell proliferation to the colony/tumor border, and 3), surface diffusion of cells at the growing edge. These characteristics were experimentally verified in the studied colonies. That these should show MBE dynamics is in strong contrast with the currently established concept of tumor growth: the kinetics of this type of proliferation rules out exponential or Gompertzian growth. Rather, a clear linear growth regime is followed. The importance of new cell movements—cell diffusion at the tumor border—lies in the fact that tumor growth must be conceived as a competition for space between the tumor and the host, and not for nutrients or other factors. Strong experimental evidence is presented for 16 types of tumor, the growth of which cell surface diffusion may be the main mechanism responsible in vivo. These results explain most of the clinical and biological features of colonies and tumors, offer new theoretical frameworks, and challenge the wisdom of some current clinical strategies

    Noncirrhotic portal hypertension in HIV-infected patients: unique clinical and pathological findings

    No full text
    Background: Liver disease of unknown cause in HIV-infected persons is rare but increasingly being reported. Noncirrhotic portal hypertension is the main feature in a subset of these patients, in whom gastrointestinal bleeding is the most frequent and potentially life-threatening clinical presentation. Methods: We describe the epidemiological, clinical and histological features of 12 HIV-positive individuals presenting with noncirrhotic portal hypertension. Results: An interpretable liver biopsy was available in 11, and cirrhosis was absent in all patients. Three patients had nodular regenerative hyperplasia of the liver, whereas eight showed morphological features previously described as ‘hepatoportal sclerosis’. In four of the later group, a distinctive lesion was noted characterized by massive absence of portal veins along with focal fibrous obliteration of small portal veins. All patients had been treated with didanosine for long periods and inflammatory and thrombotic processes hypothetically triggered by this purine analogue in the hepatic microvasculature might result in this form of obliterative portal venopathy. Conclusion: Noncirrhotic portal hypertension is a rare but unique entity presenting in HIV-positive individuals generally with prior prolonged exposure to didanosine, which shows an obliteration of portal veins as the most distinctive histological finding in the liver
