An examination of personality expression in everyday life in a Canadian sample of racialized undergraduate students.

OBJECTIVE: There is a growing body of research regarding the situations that are linked to personality expression in daily life. We examined racialized young adults' experiences of racial and ethnic cues, and variables from prior personality expression research. METHOD: We assessed Big Five personality states in racialized undergraduate students (N = 180) in the Greater Toronto Area, Canada using experience sampling methodology. Participants (Mage  = 19.85-years-old; 51% South Asian, 17% East Asian, 11% African, 11% Middle Eastern, 9% Southeast Asian, 8% Black-North American, 5% Caribbean, 3% Afro-Caribbean, 2% Central American, 2% White/European, 1% South American, 1% North African, 1% South and Central American, 1% Afro-European, 3% another) provided five assessments daily over 12 days (Nobservations  = 6980). RESULTS: We observed within-person associations from past personality expression research (e.g., participants exhibited greater conscientiousness when at school). Racial and ethnic cues from previous studies of racial and ethnic identity, stereotyping, discrimination, and prejudice were associated with situational characteristics (e.g., being in a majority White space was associated with being in public), and with Big Five personality states (e.g., racial identity salience was associated with extraversion). CONCLUSION: Results suggest that assessing sociocultural variables beyond the individual provides an opportunity for better understanding personality expression.

Outcomes of a higher calorie inpatient refeeding protocol in Asian adolescents with anorexia nervosa.

OBJECTIVE: This study aims to compare the outcomes of higher calorie refeeding (HCR) and a lower calorie refeeding (LCR) methods among a diverse sample of young Asian adolescents admitted to a tertiary institution in Asia for management of anorexia nervosa (AN). METHOD: This is a retrospective case control study of Asian adolescents who were managed using an inpatient HCR protocol (2016-2017) and an LCR protocol (2010-2014). Baseline characteristics, daily change in percent median body mass index (%mBMI), and rates of refeeding hypophosphatemia were analyzed between groups. RESULTS: A total of 125 adolescents with AN were analyzed with 61 (52%) patients in the HCR group. Mean age was 14.0 years (SD =1.5) and mean presenting %mBMI was 73.2 (SD =6.9) with mean length of stay of 11.9 days (SD = 6.6). Patients in the HCR group had significantly increased rate of change of %mBMI (M = 0.39, SD = 0.31) than patients in the LCR group (M = 0.12, SD = 0.43) (p < .001). There was an increased rate of mild hypophosphatemia in the HCR group (HCR: 46%, LCR: 22%, p = .007) but no difference in rates of moderate hypophosphatemia and no cases of severe hypophosphataemia. Lower presenting %mBMI significantly predicted the phosphate levels (p = .004). DISCUSSION: In a sample of Asian adolescents with AN, use of an HCR protocol was associated with improved rate of inpatient weight gain. There was increased risk of mild hypophosphataemia, but not moderate to severe hypophosphataemia, suggesting that an HCR protocol can be used safely with close monitoring of phosphate levels.

Developmental dysplasia of the hip.

Developmental dysplasia of the hip encompasses a range of hip abnormalities in which the femoral head and acetabulum fail to develop and articulate anatomically. Developmental dysplasia of the hip is a clinically important condition, with a prevalence of 1-2/1000 in unscreened populations and 5-30/1000 in clinically screened populations. The pathology is incongruence between the femoral head and the acetabulum, which can be caused by an abnormally shaped femoral head, acetabulum, or both. This results in a spectrum of different hip abnormalities. The precise aetiology behind developmental dysplasia of the hip is unclear, but there are a number of established risk factors. In the UK, universal clinical examination of newborns and 6-8-week-old babies is performed under the national UK newborn screening programme for developmental dysplasia of the hip (part of the Newborn and Infant Physical Examination). The physical examination of the newborn hip involves initial inspection of the infant for any of the clinical features of developmental dysplasia of the hip, followed by hip stability tests (Barlow's and Ortolani's tests). Hip ultrasound is the gold standard diagnostic and monitoring tool for developmental dysplasia of the hip in newborns and infants under 6 months of age, or until ossification of the femoral head. Some mild cases of developmental dysplasia of the hip (and the immature hip) resolve without requiring intervention; however, there are a number of treatments, both non-operative and operative, that may be used at various stages of this condition.

Clinical features for diagnosis and management of patients with PRDM12 congenital insensitivity to pain.

BACKGROUND: Congenital insensitivity to pain (CIP) is a rare extreme phenotype characterised by an inability to perceive pain present from birth due to lack of, or malfunction of, nociceptors. PRDM12 has recently been identified as a new gene that can cause CIP. The full phenotype and natural history have not yet been reported. METHODS: We have ascertained five adult patients and report their clinical features. RESULTS: Based on our findings, and those of previous patients, we describe the natural history of the PRDM12-CIP disorder, and derive diagnostic and management features to guide the clinical management of patients. CONCLUSIONS: PRDM12-CIP is a distinct and diagnosable disorder, and requires specific clinical management to minimise predictable complications.
