Outcomes of glenohumeral dysplasia after brachial plexus birth injury using the Sup-ER orthosis.

We investigated the efficacy of the supination-external rotation ('Sup-ER') orthosis, designed as a non-operative treatment to maintain normal anatomical growth of the shoulder, on the progression of glenohumeral dysplasia in patients with brachial plexus birth injuries. The Sup-ER orthosis was fabricated for 20 infants diagnosed with glenohumeral dysplasia after brachial plexus birth injuries and its success in correcting glenohumeral dysplasia was confirmed by objective calculations of the alpha angle on serial ultrasound findings and improvement in Active Movement Scale scores. Of the 20 patients, 14 had successful resolution of glenohumeral dysplasia, confirmed by shoulder abduction, shoulder flexion, external rotation and supination, Active Movement Scale scores and improving alpha angle measurements. Failure to rectify glenohumeral dysplasia, evidenced by worsening ultrasound findings and Active Movement Scale scores, necessitated a change to operative management in six patients.Level of evidence: IV.

COVID-19, economic threat and identity status: Stability and change in prejudice against Chinese people within the Canadian population.

Objectives: Previous studies found a general increase in prejudice against Chinese people during the first months of the pandemic. The present study aims to consider inter-individual heterogeneity in stability and change regarding prejudice involving Chinese people during the pandemic. The first objective is to identify and describe different trajectories of prejudice over a seven-month period during the pandemic. The second and third objectives are to test the association between trajectory group membership and antecedent variables such as: socio-demographic factors (i.e., age, gender, political affiliation) and two psychological mechanisms, namely economic threat and global citizenship identification. Methods: A representative Canadian sample (N = 3,617) according to age, gender and province of residence, was recruited for a 10-wave survey starting from April 2020 to December 2020. First, a group-based modeling approach was used to identify trajectories of prejudice. Second, a multinomial logistic regression model was used to test associations between membership in trajectories and antecedents. Results: Four trajectories were identified. The first three trajectories have a low (71.4% of the sample), high (18.5%) or very high (5.3%) level of prejudice against Chinese people which is relatively stable over time. The fourth trajectory (4.9%) reports low levels of prejudice in favor of Chinese people which become more positive throughout 2020. Regarding socio-demographic factors: gender is not associated with trajectory group membership, younger people are more likely to follow the trajectory in favor of Chinese people and conservatives are more likely to follow the highest trajectories against Chinese people. Regarding some psychological mechanisms: personal but not collective economic threat is associated with the trajectory in favor of Chinese people. Finally, the highest levels of prejudice are found when the strategy of identification is more local rather than global. Conclusion: The present study shows that Canadians differ in terms of both their level and change in prejudice against Chinese people throughout the pandemic with some socio-demographic groups being more likely than others to be associated with prejudice. The results also suggest that a promising way to tackle the major social issue of prejudice is to highlight a vision of the world where individuals are all "global citizens" facing the same challenge.

Perfil de la personalidad en sujetos internados en una unidad psiquiátrica Penitenciaria / Personality profile in patients hospitalized at a prison psychiatric unit

Presentamos los Perfiles de Personalidad obtenidos mediante la administración del MMPI-2 a dos muestras (mujeres-varones) de pacientes internados en unidades psiquiátricas carcelarias de la ciudad de Buenos Aires. Se comparan ambos perfiles entre sí y con muestras de población general. Se analizan las escalas básicas, de contenidos y suplementarias.Los perfiles de la población psiquiátrica penitenciaria presentan diferencias estadísticas significativas con las muestras de población general.

Personality profiles in psychiatric prision inmatesData on samples of prision inmates (females-males) gathered administering MMPI-2 are presented. Females and males profiles are compared as well as their personality profiles with those corresponding to a general population sample.Statistical significant differences between prision inmates profiles and general population ones were found.
