Association Of Metabolomic Biomarkers With Sleeve Gastrectomy Weight Loss Outcomes, Wendy Miller, Kathryn Ziegler, Stewart Graham, Michael Maddens, Matthew Sims

Articles

Background: Factors influencing weight loss variability following sleeve gastrectomy (SG) are not well understood. We evaluated the correlation of metabolomic biomarkers with weight loss outcomes. Methods: This prospective study evaluated the metabolomic profile of feces and serum prior to SG and three months post-SG, along with weight loss outcomes at three months post-SG (N=45). Serum and fecal samples were quantitatively profiled using a combination of 1H NMR and DI-LC-MS/MS (AbsoluteIDQ P180 kit (Biocrates, Innsbruck)). Results: Percent total weight loss (%TWL) for the lowest versus the highest weight loss tertiles (T1 vs T3) was 11.1 + 0.8% and 17.0 + 1.3%, …

Childhood Medulloblastoma, Naureen Mushtaq, Shahzadi Resham, Muhammad Shahzad Shamim, Bilal Mazhar Qureshi, Quratulain Riaz, Eric Bouffet

Section of Haematology/Oncology

Medulloblastoma is the most common malignant brain tumour in children and is a major cause of mortality and morbidity, particularly in low- and middle-income countries. It has been risk-stratified on the basis of clinical (age, metastasis and extent of resection) and histological subtypes (classic, desmoplastic and anaplastic). However, recently medulloblastoma has been sub-grouped by using a variety of different genomic approaches, such as gene expression profiling, micro-ribonucleic acid profiling and methylation array into 4 groups, namely Wingless, Sonic hedgehog, Group 3 and Group 4. This new sub-grouping has important therapeutic and prognostic implications. After acute leukaemia, brain tumour is the …

Pyloric Stenosis Leading To Sinus Venous Thrombosis; A Case Report, Amber Wright, Andrew J. Weaver, Daniel Beals

Marshall Journal of Medicine

Pyloric stenosis is typically diagnosed early and repaired after resuscitation and electrolyte correction in a timely manner. Delay in diagnosis or presentation of patient can lead to significant morbidity and even mortality. Here we present a case of pyloric stenosis leading to dehydration severe enough to lead to venous sinus thrombosis. This case highlights the importance of early detection of pyloric stenosis with timely correction of fluid status and electrolytes. Venous sinus thrombosis is a serious complication associated with our patient’s pyloric stenosis that has not yet been reported in literature.

Faculty, Staff and Student Publications

Maternal and pediatric delivery outcomes may vary in patients who underwent open fetal myelomeningocele repair and elected to deliver at the fetal center where their fetal intervention was performed versus at the referring physician’s hospital. A prospective cohort study of 88 patients were evaluated following in utero open fetal myelomeningocele repair at a single fetal center between the years 2011–2019. Exclusion criteria included patients that delivered within two weeks of the procedure (n = 6), or if a patient was lost to follow-up (n = 1). Of 82 patients meeting inclusion criteria, 36 (44%) patients were delivered at …

Section of General Surgery

Introduction: Surgical site infections (SSIs) account for 14-16% of nosocomial infections and are one of the major causes of increased morbidity, hospital stay, cost of care, and even mortality. Hypothermia as a risk factor for SSI is debated but there is lack of conclusive evidence. The present study explores the association of hypothermia with SSI.
Methodology: This is a prospective cohort study conducted on adult patients who underwent elective laparotomy. Patients were divided into two cohorts, the Hypothermia Cohort and the Normothermia Cohort, based upon episodes of hypothermia of <36⁰C in the perioperative period. SSI was diagnosed based upon …

Section of Otolaryngology, Head & Neck Surgery

Introduction: In squamous cell carcinoma (SCC) of the oral cavity, there is always a risk of occult metastasis to neck nodes in the clinically and radiologically negative neck (N0). Therefore, elective neck dissection (END) has ever been under discussion since the beginning of their routine use for the management of neck for oral carcinomas. The purpose of the current study is to identify the percentage of occult nodal metastasis to neck levels I-V in the cases of oral carcinoma who were treated for the N0 with END.

Bioactivating A Bone Substitute Accelerates Graft Incorporation In A Murine Model Of Vertical Ridge Augmentation, Jinlong Chen, Xue Yuan, Zhijun Li, Daniel J Bahat, Jill A Helms

Department of Orthopaedic Surgery Faculty Papers

OBJECTIVE: Compared to autologous bone grafts, allogeneic bone grafts integrate slowly, which can adversely affect clinical outcomes. Here, our goal was to understand the molecular mechanisms underlying graft incorporation, and then test clinically feasible methods to accelerate this process.

METHODS: Wild-type and transgenic Wnt "reporter" mice were used in a vertical ridge augmentation procedure. The surgery consisted of tunneling procedure to elevate the maxillary edentulous ridge periosteum, followed by the insertion of bone graft. Micro-computed tomographic imaging, and molecular/cellular analyses were used to follow the bone graft over time. Sclerostin null mice, and mice carrying an activated form of β-catenin …
