School of Psychology

Introduction: Young adulthood (ages 18–25) is a high-risk period for loneliness, particularly during educational transitions. Loneliness has negative consequences for mental health, physical health, and educational achievement. Psychologists conceptualize loneliness as emerging from a discrepancy between expected and experienced social connection, but this has been under-explored during young adulthood. Method: Drawing on thematic analysis of eight focus groups with 21 young adults in the UK, this paper explores the differences between retrospective expectations and experience of social connection during the transition into university and the implications for loneliness. Results: Whilst social expectations, experiences, and preferences vary considerably, young adults' perception …

Early Detection Of Amniotic Fluid Embolism Leading To Extracorporeal Membrane Oxygenation Prior To Cardiac Arrest, Enad Haddad, Hamza Muhammadzai, Shayan Iqbal Khan, Angad Bedi, Rajesh Patel

Abington Jefferson Health Papers

Amniotic fluid embolism is a life-threatening peripartum condition with high morbidity and mortality rates. It is defined as the passage of fetal material into the maternal circulation which elicits a multisystem reaction that can lead to disseminated intravascular coagulopathy and severe hemodynamic instability. Despite established diagnostic criteria for amniotic fluid embolism, its identification relies heavily on clinical judgment, and early diagnosis is key to patient survival. In several cases, early utilization of extracorporeal membrane oxygenation support has provided a salvage approach to correct cardiopulmonary collapse. Herein, we present a case of successful application of venoarterial extracorporeal membrane oxygenation in a …

Oxidized Phospholipid And Transcriptomic Signatures Of Thc-Related Vaping Associated Lung Injury, Tomeka L Suber, Zeyu Xiong, Janet S Lee, Et Al.

2020-Current year OA Pubs

E-cigarette/vaping-associated lung injury (EVALI) is strongly associated with vitamin E acetate and often occurs with concomitant tetrahydrocannabinol (THC) use. To uncover pathways associated with EVALI, we examined cytokines, transcriptomic signatures, and lipidomic profiles in bronchoalveolar lavage fluid (BALF) from THC-EVALI patients. At a single center, we prospectively enrolled mechanically ventilated patients with EVALI from THC-containing products (N = 4) and patients with non-vaping acute lung injury and airway controls (N = 5). BALF samples were analyzed by Luminex multiplex assay, RNA sequencing, and mass spectrometry. After treating BEAS-2B lung epithelial cells with vaping and non-vaping BALF, LDH release was quantified. …

Carboxyl Ester Lipase Hybrid 1 (Cel-Hyb1) Haplotypes Confer Varying Risk For Chronic Pancreatitis, Gergő Berke, Xunjun K Xiao, Mark E Lowe, Et Al.

2020-Current year OA Pubs

The CEL-HYB1 hybrid allele of the carboxyl ester lipase (CEL) gene and its pseudogene (CELP) has been associated with chronic pancreatitis (CP). Recent work indicated that amino acid positions 488 and 548 in CEL-HYB1 determined pathogenicity. Haplotype Thr488-Ile548 was associated with CP while haplotypes Thr488-Thr548 and Ile488-Thr548 were benign. However, functional analysis revealed that Thr488 is the primary determinant of CEL-HYB1 misfolding and associated endoplasmic reticulum (ER) stress. To address this contradiction, we analyzed a cohort from Hungary and found significantly increased CEL-HYB1 carrier frequency in CP cases (9/319, 2.8%) versus controls (5/618, 0.8%), yielding an odds ratio of 3.6 …
