Background: Metabolic and bariatric surgery (MBS) leads to beneficial and sustained outcomes. However, many patients evidence weight recurrence and psychosocial functioning may be associated with weight recurrence. The Minnesota Multiphasic Personality Inventory - 3 (MMPI-3) is validated for use in presurgical MBS evaluations and likely has clinical utility in understanding weight recurrence and other aspects of postoperative functioning.

Objective: The objective of the current investigation is to understand how postoperative psychosocial functioning relates to weight recurrence and other behaviors and constructs 6 years after MBS.

Setting: Cleveland Clinic Bariatric and Metabolic Institute.

Methods: A sample of 163 participants consented to take a battery of self-report measures related to psychological functioning, eating behaviors, adherence, alcohol misuse, and quality of life along with their postoperative weight. MMPI-3 scale scores were prorated from the Minnesota Multiphasic Personality Inventory - 2 - Restructured Form (MMPI-2-RF) or scored from the Minnesota Multiphasic Personality Inventory - 2 - Restructured Form - Expanded (MMPI-2-RF-EX).

Results: Weight recurrence was quite variable in this sample. Postoperative MMPI-3 scales related to emotional/internalizing dysfunction were modestly associated with higher weight recurrence. Postoperative MMPI-3 scale scores also demonstrated associations with other postoperative outcomes including measures of eating behaviors, adherence, alcohol misuse, and quality of life.

Conclusions: Postoperative psychosocial functioning as assessed by the MMPI-3 was associated with weight recurrence and a number of other problematic psychological outcomes beyond weight recurrence.

Background: Fulminant myocarditis (FM) is a potentially lethal disease with a wide spectrum of clinical presentation, thus making the diagnosis hard to depict. In cases where acute circulatory failure occurs venoarterial (VA) extracorporeal membrane oxygenation (ECMO) support is a valid management strategy, especially in the pediatric and adult patients. This study aims to report the results of VA ECMO for FM in our Institution.

Background: Neuroblastoma (NB) is a highly heterogeneous and common pediatric malignancy with a poor prognosis. Ferroptosis, an iron-dependent cell death pathway, may play a crucial role in NB tumor progression and immune response. This study aimed to investigate ferroptosis in NB to identify potential therapeutic targets and develop predictive models for prognosis and recurrence.

Pheochromocytoma is a catecholamine-secreting tumor that arises from the medullary chromaffin cells but can rarely be extra-adrenal in origin. We present a case of a 16-year-old female patient with uncontrolled hypertension, despite being on lisinopril and metoprolol, and associated left-sided chest pain, recurrent headaches, and an unintentional weight loss of 10 pounds in one month. Laboratory work-up showed a markedly elevated plasma metanephrine level of 4463.

Introduction: Existing research suggests an association between smoking and the incidence of recurrent aphthous stomatitis (RAS); however, the causal relationship remains ambiguous. We employed Mendelian randomization (MR) to clarify the potential causal association between smoking and the risk of developing RAS.

Methods: We utilized genome-wide association study (GWAS) sequencing data related to smoking from the Finnish database as instrumental variables (IVs) and GWAS data for RAS from the UK Biobank (UKB) as the outcome to perform a two-sample MR analysis.
