Background Although the diagnosis of Borderline Personality Disorder (BPD) during adolescence has been questioned, many recent studies have confirmed its validity. However, some clinical manifestations of BPD could be identifiable in adolescents with other pathologies, such as Attention-Deficit/Hyperactivity Disorder (ADHD). The objective of the present study is to examine the capacity of the self-report Borderline Personality Features Scale Children-11 (BPFSC-11) to discriminate between BPD and ADHD adolescents. Methods One hundred and forty-five participants were grouped based on their diagnosis: 58 with BPD, 58 with ADHD, and 29 healthy volunteers as a control group. Between-group differences and the ROC curve were performed to test if the total score for the BPFSC-11 and/or its factors can significantly discriminate between BPD and other adolescent groups. Results The results show that the total BPFSC-11 score has good discriminant capacity among adolescents diagnosed with BPD, ADHD and healthy volunteers. However, different patterns of discriminative capacity were observed between the three groups for emotional dysregulation and impulsivity/recklessness factors. Conclusions Our results support the hypothesis that the BPFSC-11 is an adequate instrument for discriminating between BPD and ADHD in adolescents, who can present significant psychopathological overlap. Tools to identify BPD in adolescence, as well as for better differential diagnosis, would improve the possibility of offering specific treatments targeting these populations.

Microplastics have become one of the most important environmental problems in recent years. These pollutants come from everyday human activities, both industrial and domestic, and if not properly managed, can end up in the environment, with negative consequences for the ecosystem. One of the most important pathways for these microplastics to enter the environment are the discharges from wastewater treatment plants. Although a high removal of microplastics can be achieved with conventional treatments, these are not specifically designed for the removal of this pollutants, therefore large amounts of them are discharged together with the treated wastewater. The use of advanced treatments such as intermittent sand filtration can enable higher removal of microplastics from the water line, reducing pollution in natural water bodies, improving the water quality and allowing reuse of the treated water as a by-product with a low operating and investment costs. To understand and analyse the performance of this advanced treatment in removing microplastics, three laboratory-scale filters, filled with three different substrates -silica sand, two halves of sand and coke, and coke- were tested. Synthetic wastewater with a known amount of polypropylene microplastics and real wastewater from the secondary settler were used to study the efficiency of the filters. The samples were analysed before and after treatment in order to quantify the microplastics existing, classify them according to their morphology and identify the most abundant plastic polymers in the case of the real wastewater samples. This provided a preliminary analysis of the efficiency of this technology, the behaviour of different substrates in the removal of microplastics, the removal mechanisms depending on their morphology and their feasibility as a full-scale plant in a real, small wastewater treatment plant.

En Argentina, la obesidad en adultos es una problemática con una prevalencia media de 25,4%. En la relación entre COVID-19 y obesidad, se observa mayor prevalencia de sobrepeso/obesidad y enfermedad severa entre los pacientes con COVID-19. Por ello, el objetivo del estudio fue conocer las características clínicas y epidemiológicas en pacientes con diagnóstico de obesidad sobrevivientes a la infección por SARS-CoV-2. MÉTODOS: Se realizó un estudio observacional descriptivo y analítico de corte transversal. Se aplicó una encuesta autoadministrada. RESULTADOS: La mediana de edad fue 41 años, y hubo un 69,9% de mujeres. Los síntomas de presentación más prevalentes fueron astenia (86,7%), anosmia (64,5%) y tos (64%). Con respecto a los síntomas persistentes luego de las 12 semanas del diagnóstico, los más prevalentes fueron astenia (52,9%), trastornos de sueño (32,4%) y falta de concentración/memoria (31,7%). Hubo mayor riesgo en mujeres (OR: 2,86; IC95%: 2,23-3,67) con obesidad (OR: 1,58; IC95%: 1,16-2,16). La enfermedad grave en obesos fue casi el triple comparado con no obesos (15,7% vs. 5,4%; p
