RESUMO
INTRODUCTION: The aim of the present study is to analyze the clinical-radiological outcomes of patients undergoing knee prosthesis revision surgery using constrained condylar prosthesis (LCCK; Zimmer-Biomet). MATERIAL AND METHODS: Retrospective study of 89 patients operated on between the years 2008 and 2020 with a minimum of 2 years of follow-up. Clinical outcomes were evaluated using the WOMAC Index score and KOOS scales. Radiological results (radiolucent lines, osteolysis, and cortical hypertrophy) were evaluated by two independent observers. Implant survival was analyzed using the Kaplan-Meier method. RESULTS: At the end of follow-up, a mean WOMAC Index score of 78.67 and KOOS score of 68.8 were obtained. Radiolucent lines (both non-progressive and progressive) were detected in 83.3% of the patients in the sample. Areas of osteolysis > 5 mm around the components were present in 6.75%. Cortical hypertrophy was seen around the femoral stem in 20.3% of cases, around the tibial stem in 20.3% and around both components in 6.76%. No statistically significant relationship was found between the presence of radiolucent lines, osteolysis or cortical hypertrophy with functional results. Implant survival was 88.1% at 13 years. CONCLUSION: The present study shows high survival of LCCK prosthesis in revision surgery. The progressive radiolucencies, were associated with worst clinical outcome.

Identity fusion is a visceral feeling of oneness with a group, known to strongly motivate extreme pro-group behaviour. However, the evidence on its causes is currently limited, primarily due to the prevalence of cross-sectional research. To address this gap, this study analysed the evolution of fusion in response to a massive collective ritual, Korrika-a race in support of the Basque language-, over three time periods: before (n = 748) and immediately following participation (n = 402), and 7 weeks thereafter (n = 273). Furthermore, we explored the potential mediating roles of two key factors: perceived emotional synchrony, a sense of emotional unity among participants that emerges during collective rituals, and kama muta (moved by love), an unexplored emotion in relation to fusion, which arises from feelings of shared essence. The proportion of fused participants increased significantly after participation and remained stable for at least 7 weeks. Perceived emotional synchrony and kama muta apparently explained the effect of participants' behavioural involvement in the ritual on subsequent fusion, but only among those who were not previously fused with Korrika participants. We conclude that emotional processes during collective rituals play a fundamental role in the construction of identity fusion.

The neo-Durkheimnian model suggests that feedback and emotional communion between participants during a collective gathering (i.e., perceived emotional synchrony: PES) is one of the key mechanisms of collective processes. This shared emotional experience gives rise, in turn, to more intense emotions, this being one of the explanatory models of the positive psychological effects of collective participation. Through a quasi-longitudinal design of three measurement-times (N = 273, 65.9% women; age: 18-70, M = 39.43, SD = 11.64), the most massive social mobilization that is celebrated in favor of the Basque language in the Basque Country (Korrika) was analyzed. Repeated measures and sequential mediation analyzes supported the model. The effect of participation on social integration was mediated by the increase in emotions of enjoyment through PES; the effect on social acceptance, social contribution, and social actualization was mediated by increased kama muta through PES; the effect on collective empowerment was mediated by the increase in self-transcendent emotions through PES; and the effect on remembered well-being was partially mediated by PES. Finally, it was also verified for the first time that the effect of participation on social integration, social acceptance and social actualization was maintained through PES (but not through emotions) for at least 6-7 weeks after the event ended. Also, it is concluded that Kama muta is a relevant emotion during collective gatherings.
RESUMO
Social identity is a factor that is associated with well-being and community participation. Some studies have shown that ethnic identity goes along with empowerment, and that interaction between the two leads to greater indices of well-being and community participation. However, other works suggest a contextual circumstance (i.e., perceiving one's own group as a minority and/or being discriminated) may condition the nature of these relations. By means of a cross-sectional study, we analyzed the relations of social identification (or identity fusion) and collective psychological empowerment with personal well-being, social well-being and community participation in a sample of Basques. A total of 748 Basques participated (63.1% women; age M = 39.28; SD = 12.13). Individuals who were highly identified or fused with Basque speakers and who were highly empowered showed higher indices of well-being (both personal and social) and of community participation than non-fused individuals with low empowerment. The results also suggest that social identification (or identity fusion) offsets the negative effects of perceiving the group as a linguistic minority. Collective psychological empowerment proved to be an especially relevant factor that needs to continue to be explored.
RESUMO
AIMS: The aim of this study was to identify factors related to a decline in function following a wrist fracture. METHODS: Observational, prospective cohort study done in five public hospitals of the Basque Health Service. We recruited adults aged 65 or older with a wrist fracture due to a fall who attended the emergency department (ED) of one of these hospitals. Sociodemographic and clinical data were collected, along with information about health-related quality of life (HRQoL) and functionality. RESULTS: A decline in function 6 months after the fracture was more likely among women (OR=3.409; 95% CI=1.920-6.053), patients receiving institutional help before the fracture (OR=5.717; 95% CI=1.644-19.883), patients who developed fracture-related complications within 6 months of the fall (OR=5.015; 95% CI=1.377-18.268), patients who visited an ED within 6 months of the fall (OR=1.646; 95% CI=1.058-2.561), patients with a displaced fracture (OR=1.595; 95% CI=1.106-2.300), and patients who broke the dominant hand (OR=1.464; 95% CI=1.019-2.103). Better baseline HRQoL and function were associated with smaller declines in function 6 months after the fall. Eighteen months after the fall, decline in function was more likely among women (OR=2.172; 95% CI=1.138-4.144) and patients visiting an ED because of fracture-related complications (OR=1.722; 95% CI=1.113-2.663). Better HRQoL and dependency level at baseline were associated with less decline in function 18 months after the fracture. DISCUSSION: Two different models identified several parameters related to declines in upper extremity function 6 and 18 months after the fracture. CONCLUSIONS: These results can help develop preventive actions needed to avoid or reduce the consequences of these falls.

OBJETIVO: Valorar y revisar en nuestra serie la incidencia de los diferentes tipos de hipospadias, así como el porcentaje de complicaciones sufridas mediante el empleo de diferentes técnicas y materiales. MÉTODOS: 130 pacientes afectos de hipospadias e intervenidos quirúrgicamente durante los últimos 6 años. Sección de Urología Pediátrica. RESULTADOS: H. Glandares (13). H. BalanoPrepuciales (56). H. Peneano Distales (42). H. Peneano Medios (9). H. Peneano Proximales (2). H. Penoescrotales (8).Con respecto a las técnicas empleadas: Meatotomía Mickulitz (6). MAGPI (24). Mathieu (77). Crawford (5). Onlay (7). Duckett (3). Retik (4). Duplay (1). Denis-Brown (2). Transposición penoescrotal (1). Con respecto a las principales complicaciones: Fístulas (20). Hematomas (4). Estenosis Meato Uretral (4). Infección (3). Megauretra (3). Necrosis Cutánea (1). CONCLUSIONES: Realizamos la intervención aproximadamente hacia los 18 meses de edad, teniendo un porcentaje de complicaciones, en cuanto a fistulización cercano al 15 por ciento, comparable al de otras series de la literatura, aunque desde que utilizamos material reabsorbible monofilamento, el número de fistulizaciones se ha visto reducido notablemente, del 20 por ciento acerca del 5 por ciento, y aunque influyen otros factores, creemos que la menor reacción de cuerpo extraño sobre el tejido es responsable en gran medida de este descenso (AU)
