Francis Daniels Moore: one of the brightest minds in the surgical field.

Francis Daniels Moore was a pioneer ahead of his time who made numerous landmark contributions to the field of surgery, including the understanding of metabolic physiology during surgery, liver and kidney transplant, and the famous Study on Surgical Services of the United States (SOSSUS) report of 1975 that served for decades as a guideline for development of surgical residencies. He was the epitome of what a physician should be, a compassionate and dedicated surgeon, innovative scientist, and a medical professional dedicated to quality medical education across all specialties

An Unusual Case of a Gastric Xanthoma: A Case Report.

Gastric xanthomas are rare tumor-like lesions, most commonly occurring in the antral region. We set out to describe a patient with a history of Barrett\u27s esophagus status post two radiofrequency ablations (RFAs) and an endoscopic mucosal resection (EMR) who developed a gastric xanthoma just below the Z-line with recurrent esophageal metaplasia. Histopathological confirmation of xanthomas are needed to rule out malignancy. While gastric xanthomas themselves are benign conditions, regular follow-up is recommended if there is a high index of suspicion of malignancy or alarming symptoms develop

Impact of COVID-19 on a Free Clinic Patient Population

The Robert R. Frank Student Run Free Clinic at WSUSOM, surveyed patients to determine the impact of the COVID-19 pandemic on its patient population. The study examined any challenges faced in food, financial status, transportation, and healthcare. A Qualtrics survey was administered with ethnicity, age, and gender as controls, while testing patient responses to social factors using the Likert scale. The survey was targeted to a portion of the clinic’s patient pool (n=33) over a span of three months and responses were analyzed using SPSS 26 regression analysis, ANOVA, and paired sample T-tests. Significant responses were across demographics, categories of impact, and pre/post COVID-19. Results show that access to fresh foods was severely impacted by COVID-19 (t = -3.19, p\u3c 0.05). Linear regression models show a correlation between difficulty accessing healthcare and medications, before and after COVID-19, indicating that the pandemic may have exacerbated pre-existing barriers to treatment (correlation = 0.810). Financial status has been the most affected with many patients indicating changes in employment or income status. 55% of the participants noted a greater use of savings or retirement money to make ends meet. A moderate correlation (0.471) was found between the use of public transportation prior to the pandemic and transportation barriers during the pandemic. We have decided to compile resources to address the needs based on the study results. Future research includes a longitudinal, follow-up survey to gauge any changes. Limitations include the study sample size and participation bias among the patient population

Quantification and Localization of Mast Cells in Periapical Lesions

Background: Periapical lesions occur in response to chronic irritation in periapical tissue, generally resulting from an infected root canal. Specific etiological agents of induction, participating cell population and growth factors associated with maintenance and resolution of periapical lesions are incompletely understood. Among the cells found in periapical lesions, mast cells have been implicated in the inflammatory mechanism. Aim: Quantifications and the possible role played by mast cells in the periapical granuloma and radicular cyst. Hence, this study is to emphasize the presence (localization) and quantification of mast cells in periapical granuloma and radicular cyst. Materials and Methods: A total of 30 cases and out of which 15 of periapical granuloma and 15 radicular cyst, each along with the case details from the previously diagnosed cases in the department of oral pathology were selected for the study. The gender distribution showed male 8 (53.3%) and females 7 (46.7%) in periapical granuloma cases and male 10 (66.7%) and females 5 (33.3%) in radicular cyst cases. The statistical analysis used was unpaired t‑test.Results: Mean mast cell count in periapical granuloma subepithelial and deeper connective tissue, was 12.40 (0.99%) and 7.13 (0.83%), respectively. The mean mast cell counts in subepithelial and deeper connective tissue of radicular cyst were 17.64 (1.59%) and 12.06 (1.33%) respectively, which was statistically significant. No statistical significant difference was noted among males and females.Conclusion: Mast cells were more in number in radicular cyst. Based on the concept that mast cells play a critical role in the induction of inflammation, it is logical to use therapeutic agents to alter mast cell function and secretion, to thwart inflammation at its earliest phases. These findings may suggest the possible role of mast cells in the pathogenesis of periapical lesions. Keywords: Mast cells, Periapical granuloma, Radicular cyst, Toluidine blu

Functional characterisation of substrate-binding proteins to address nutrient uptake in marine picocyanobacteria.

Marine cyanobacteria are key primary producers, contributing significantly to the microbial food web and biogeochemical cycles by releasing and importing many essential nutrients cycled through the environment. A subgroup of these, the picocyanobacteria (Synechococcus and Prochlorococcus), have colonised almost all marine ecosystems, covering a range of distinct light and temperature conditions, and nutrient profiles. The intra-clade diversities displayed by this monophyletic branch of cyanobacteria is indicative of their success across a broad range of environments. Part of this diversity is due to nutrient acquisition mechanisms, such as the use of high-affinity ATP-binding cassette (ABC) transporters to competitively acquire nutrients, particularly in oligotrophic (nutrient scarce) marine environments. The specificity of nutrient uptake in ABC transporters is primarily determined by the peripheral substrate-binding protein (SBP), a receptor protein that mediates ligand recognition and initiates translocation into the cell. The recent availability of large numbers of sequenced picocyanobacterial genomes indicates both Synechococcus and Prochlorococcus apportion >50% of their transport capacity to ABC transport systems. However, the low degree of sequence homology among the SBP family limits the reliability of functional assignments using sequence annotation and prediction tools. This review highlights the use of known SBP structural representatives for the uptake of key nutrient classes by cyanobacteria to compare with predicted SBP functionalities within sequenced marine picocyanobacteria genomes. This review shows the broad range of conserved biochemical functions of picocyanobacteria and the range of novel and hypothetical ABC transport systems that require further functional characterisation

Stent vs. Stent-less Ileal Conduits After Radical Cystectomies: Is There Difference In Early Postoperative Outcomes?

Placing ureteral stents at the ureteroileal anastomosis for radical cystectomy with ileal conduit (RCIC) diversion has long been common practice, which has recently been called into question. In this study, we aim to investigate the difference in 30-day outcomes between patients who did and did not receive ureteral stents after RCIC.https://jdc.jefferson.edu/urologyfposters/1003/thumbnail.jp

Imaging fetal anatomy.

Due to advancements in ultrasound techniques, the focus of antenatal ultrasound screening is moving towards the first trimester of pregnancy. The early first trimester however remains in part, a 'black box', due to the size of the developing embryo and the limitations of contemporary scanning techniques. Therefore there is a need for images of early anatomical developmental to improve our understanding of this area. By using new imaging techniques, we can not only obtain better images to further our knowledge of early embryonic development, but clear images of embryonic and fetal development can also be used in training for e.g. sonographers and fetal surgeons, or to educate parents expecting a child with a fetal anomaly. The aim of this review is to provide an overview of the past, present and future techniques used to capture images of the developing human embryo and fetus and provide the reader newest insights in upcoming and promising imaging techniques. The reader is taken from the earliest drawings of da Vinci, along the advancements in the fields of in utero ultrasound and MR imaging techniques towards high-resolution ex utero imaging using Micro-CT and ultra-high field MRI. Finally, a future perspective is given about the use of artificial intelligence in ultrasound and new potential imaging techniques such as synchrotron radiation-based CT to increase our knowledge regarding human development

The dilemma of arranged marriages in people with epilepsy. An expert group appraisal

INTRODUCTION: Matrimony remains a challenging psychosocial problem confronting people with epilepsy (PWE). People with epilepsy are less likely to marry; however, their marital prospects are most seriously compromised in arranged marriages. AIMS: The aim of this study was to document marital prospects and outcomes in PWE going through arranged marriage and to propose optimal practices for counseling PWE contemplating arranged marriage. METHODS: A MEDLINE search and literature review were conducted, followed by a cross-disciplinary meeting of experts to generate consensus. RESULTS: People with epilepsy experience high levels of felt and enacted stigma in arranged marriages, but the repercussions are heavily biased against women. Hiding epilepsy is common during marital negotiations but may be associated with poor medication adherence, reduced physician visits, and poor marital outcome. Although divorce rates are generally insubstantial in PWE, divorce rates appear to be higher in PWE undergoing arranged marriages. In these marriages, hiding epilepsy during marital negotiations is a risk factor for divorce. CONCLUSIONS: In communities in which arranged marriages are common, physicians caring for PWE are best-equipped to counsel them about their marital prospects. Marital plans and aspirations should be discussed with the family of the person with epilepsy in a timely and proactive manner. The benefits of disclosing epilepsy during marital negotiations should be underscored
